Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Basis of presentation

The condensed consolidated financial statements of NeoPhotonics Corporation (“NeoPhotonics” or the “Company”) as of March 31, 2013 and December 31, 2012 and for the three months ended March 31, 2013 and 2012, have been prepared in accordance with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, the Company has omitted certain information and notes normally provided in the Company’s annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the interim periods. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. generally accepted accounting principles (“U.S. GAAP”). These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.

Due to rounding, numbers presented in this document may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures.

Consolidation

The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the consolidated accounts of the Company and its majority owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenue and expenses during the reporting period. Significant estimates made by management include: the useful lives of property, plant and equipment and intangible assets as well as future cash flows to be generated by those assets; allowances for doubtful accounts; valuation allowances for deferred tax assets; reserves for excess and obsolete inventories and the valuations and recognition of stock-based compensation, among others. Actual results could differ from these estimates.

Business Combinations—Acquisition Accounting

Under the acquisition method of accounting, the Company allocates the purchase price of acquired companies to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The Company records the excess of purchase price over the aggregate fair values of the tangible and identifiable intangible assets as goodwill. The Company determines the fair values of assets acquired and liabilities assumed. To establish fair value, the Company measures the price that would be received to sell an asset or paid to transfer a liability in an ordinary transaction between market participants. The measurement assumes the highest and best use of the asset by the market participants that would maximize the value of the asset or the group of assets within which the asset would be used at the measurement date, even if the intended use of the asset is different.

The Company estimates the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expenses. The Company estimates the future cash flows to be derived from such assets, and these estimates are used to determine the fair value of the assets. If any of these estimates change, depreciation or amortization expenses could be changed and/or the value of our intangible assets could be impaired.

Acquisition related costs, including finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees are accounted for as expenses in the periods in which the costs are incurred or the services are received.

Note 2. Significant accounting policies

There have been no changes in the Company’s significant accounting policies for the three months ended March 31, 2013, as compared to the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Recent accounting pronouncements

In February 2013, the Financial Accounting Standard Board (“FASB”) issued amendments to the FASB Accounting Standard Codification to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments require new disclosures for items reclassified out of accumulated other comprehensive income (“AOCI”), including (1) changes in AOCI balances by component and (2) significant items reclassified out of AOCI. The guidance does not amend any existing requirements for reporting net income or OCI in the financial statements. The standards update was effective for reporting periods beginning after December 15, 2012, to be applied prospectively. Early adoption is permitted. As this guidance only requires expanded disclosures, the adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.

In March 2013, the FASB issued amendments to the FASB Accounting Standard Codification, which indicates that the entire amount of a cumulative translation adjustment related to an entity’s investment in a foreign entity should be released when there has been a (i) sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity, (ii) loss of a controlling financial interest in an investment in a foreign entity, or (iii) step acquisition for a foreign entity. The amendments are effective prospectively for fiscal years beginning after December 15, 2013. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact to the Company’s consolidated financial statements.

Note 3. Discontinued operations

In the fourth quarter of 2011, the Company initiated a plan to sell a component of its business, Broadband, a subsidiary in China. The Company decided to sell Broadband because the nature of its operations was different than the core technology and strategy of the Company. On January 11, 2012, the Company entered into a purchase agreement with Guangdong Rainbow Electronic Ltd. (Rainbow) to dispose of its 100% equity interest in Broadband for a total cash consideration of RMB 13.0 million ($2.1 million). The transaction closed on March 13, 2012. The Company recognized a gain of $0.6 million on the sale of Broadband, representing the difference between the consideration received and the net assets transferred to Rainbow, net of tax. The gain was included in income from discontinued operations, net of tax in the statement of operations for the three months ended March 31, 2012.

The results of operations associated with Broadband are presented as discontinued operations in the Company’s consolidated statements of operations for the three months ended March 31, 2013 and 2012. Revenue and the components of net income related to the discontinued operations for all periods were as follows (in thousands):

Realized gains and losses on the sale of marketable securities during the three months ended March 31, 2013 and 2012 were immaterial. The Company did not recognize any impairment losses on its marketable securities during the three months ended March 31, 2013 and 2012.

Note 6. Business Combination

Optical Components Business Unit (OCU)

On March 29, 2013 (the “closing date”) the Company acquired certain assets and assumed certain liabilities related to the Optical Components Business Unit (the “OCU”) of Lapis Semiconductor Co., Ltd., a wholly owned subsidiary of Rohm Co., Ltd (“Lapis”) of Japan with the intention of operating the OCU as an ongoing business.

The OCU is a leader in high speed semiconductor and high speed laser and photodetector devices for communications networks. The Company believes the acquisition will expand the Company’s solutions for high speed telecom and datacom applications and strengthen the Company’s customer base in Japan.

The total consideration paid by the Company for the OCU was approximately $35.5 million, consisting of cash of $14.6 million, notes payable of $11.1 million and assumed liabilities of $9.7 million. The cash of $14.6 million includes $2.0 million that was withheld and placed into escrow to cover certain indemnity obligations from the closing date through March 29, 2014. The notes payable of $11.1 million are to be paid in three equal installments on the first, second and third anniversaries of the closing date. Each year an additional amount calculated as 1.5% per year of the unpaid balance of the notes becomes due. Lapis retains a lien on the land and building sold until the third payment is paid. The purchase price consideration and payment of notes payable are denominated in Japanese Yen.

In connection with the acquisition, the Company incurred approximately $3.2 million in acquisition-related costs related primarily to investment banking, legal, accounting and other professional services. The acquisition costs were expensed as incurred and were included in general and administrative expenses in the Company’s consolidated statement of operations in the first quarter of 2013.

The OCU’s results of operations between the closing date of March 29, 2013 and the Company’s quarter end date of March 31, 2013 were immaterial.

Purchase Price Allocation

The Company accounted for its acquisition of the OCU assets and assumed liabilities using the acquisition method of accounting for business combinations. The OCU’s tangible and identifiable intangible assets acquired and liabilities assumed were recorded based upon their estimated fair values as of the closing date of the acquisition. The excess of purchase price over the value of the net assets acquired was recorded as goodwill. The Company’s purchase price allocation is preliminary. The fair values of acquired assets and liabilities may be further adjusted as additional information becomes available during the allocation period. Additional information that may become available subsequently and may result in changes in the values allocated to various assets and liabilities includes, but is not limited to, pension and retirement liabilities, asset retirement obligations, inventory fair value and the working capital adjustments to be agreed with Lapis. Any changes in the values allocated to tangible and identified intangible assets acquired and liabilities assumed during the allocation period may result in material adjustments to goodwill. The following table summarizes the preliminary acquisition accounting and the tangible and intangible assets acquired as of the date of acquisition (in thousands):

The adjustments to measure the assets acquired and liabilities assumed at the preliminary fair value are described below:

Net Tangible Assets

The OCU’s tangible assets acquired and liabilities assumed as of March 29, 2013 were reviewed and adjusted to their preliminary fair value. The Company adjusted the OCU’s historical value of property, plant and equipment to an estimate of depreciated replacement cost, adjusted for economic obsolescence. The Company amortizes property, plant and equipment over estimates lives of 2 to 10 years, and amortizes the expense to cost of goods sold and operating expense. The fair value of inventory acquired was determined using a net realizable value approach based upon the expected sales value of the inventory, less any costs to complete and selling costs along with a reasonable profit margin based on historical and expected results.

Intangible Assets

Developed technology represents products that have reached technological feasibility. The OCU’s current product offerings include high speed semiconductor and high speed laser and photodetector devices for communication networks. The fair value of developed technology intangibles acquired was determined by using a royalty-avoidance method. The share of future revenue relating to current technology was forecasted, using an estimate for obsolescence such that the share declines over time. A royalty rate of two percent was used to calculate royalty savings on that revenue that are avoided since the Company owns the technology and does not need to license it from other parties. The after-tax royalty savings was then discounted to present value using the Company’s discount rate. The Company amortizes the developed technology intangible assets over estimated lives of 4 to 5 years, and amortization expense is recorded to cost of goods sold.

The customer relationships asset represents the value of the ability to sell existing, in-process, and future versions of the technology to the OCU existing customer base. The Company utilized the excess earnings method, estimating future cash flows that will result from existing customers given assumed retention rates, and then discounting those flows to their present value using the Company’s discount rate. The Company amortizes the customer relationships intangible asset over an average estimated life of 6 years, and amortization expense is recorded to operating expenses.

The weighted average amortization period for the total amount of intangible assets acquired is 5.1 years.

Goodwill

Goodwill is the excess of the purchase price over the preliminary fair value of the underlying net tangible and identifiable intangible assets. In accordance with applicable accounting standards, goodwill is not amortized but instead is tested for impairment at least annually or more frequently if certain indicators are present. The Company expects that goodwill of $2.2 million will be deductible for tax purposes.

Pro Forma Financial Information (unaudited)

The unaudited financial information in the table below summarizes the combined results of operations of the Company with the results of OCU prior to the acquisition, on a pro forma basis, as though the companies had been combined as of the beginning of the period presented. The pro forma financial information for the period presented includes the business combination accounting effects on adjustments related to the fair value of acquired inventory and fixed assets, amortization charges from acquired intangible assets and related tax effects of these adjustments, where applicable. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved had the acquisition taken place at the beginning of the period presented, nor does it intend to be a projection of future results.

Notes payable

The Company frequently directs its banking partners to issue notes payable to its suppliers in China in exchange for accounts payable. These banks issue notes to vendors and issue payment to the vendors upon redemption. The Company owes the payable balance to the issuing bank. These notes are unsecured, noninterest bearing and are due approximately six months after issuance.

Notes payable for OCU acquisition

In connection with acquisition of OCU on March 29, 2013, the Company is obligated to pay $11.1 million in three equal installments on the first, second and third anniversaries of the closing date for the purchase of the real estate used by the OCU. The payment is denominated in Japanese Yen. The amount presented in the table is the short-term portion of $3.7 million and the long-term portion of $7.4 million. The obligation bear interest at 1.5% per year and the real property is security for the loan.

Long-term debt

The Company has lending arrangements with several financial institutions, including a loan and security agreement with Comerica Bank in the U.S., which has been amended several times. As of December 31, 2012, the Company’s loan and security agreement in the U.S. included the following components:

•

As of December 31, 2012, $8.0 million was outstanding under the revolving line of credit agreement and $0.0 million was available for borrowing. Borrowings under this facility bear interest at a rate of LIBOR plus 2%.

•

As of December 31, 2012, no amounts were outstanding under the equipment advance line advance and all $7.0 million was available for borrowing. Borrowings under this facility would bear interest at a rate of LIBOR plus 2%.

•

As of December 31, 2012, $14.2 million was outstanding under the acquisition advance and $5.8 million was available for borrowing. The advances bear interest at a rate of LIBOR plus 2%.

On March 21, 2013, the Company amended and restated in its entirety Loan and Security Agreement with the same bank and added East-West Bank as a lender. The components of the available credit facilities as of March 31, 2013 as follows:

•

As of March 31, 2013, $12.0 million was outstanding under the revolving line of credit agreement and $8.0 million was available for borrowing. Amounts are due on or before March 2016 and borrowings under this revolving line of credit include an interest rate option of the Prime rate plus 4.75% or LIBOR plus 2.5%. Until March 31, 2013, the Prime option was used, and in April 2013, the LIBOR option was selected.

•

As of March 31, 2013, $28.0 million was outstanding under the term loan of the credit facility and interest is payable quarterly in arrears; the principal is paid in equal quarterly installments over the term of the loan ending in June 2017. Borrowings under the term loan include an interest rate option of the Prime rate plus 5.0% or LIBOR plus 2.75%. Until March 31, 2013, the Prime option was used, and in April 2013, the LIBOR option was selected.

The Company’s U.S. loan and security agreement requires us to maintain specified financial covenants, including a liquidity ratio, restricts its ability to incur additional debt or to engage in specified transactions and is secured by substantially all of its U.S. assets, other than intellectual property assets. As of March 31, 2013 and December 31, 2012, the Company was in compliance with the covenants contained in this agreement.

In connection with the original loan and security agreement, the Company issued a warrant on December 20, 2007 to Comerica Bank to purchase 4,482 shares of common stock at an exercise price of $29.00 per share. As of March 31, 2013 and 2012, the warrant had not been exercised.

Note 9. Commitments and contingencies

Leases

The Company leases various facilities under noncancelable operating leases. As of March 31, 2013, the future minimum commitments under all operating leases are as follows (in thousands):


2013 (remaining 9 months)	$	1,593
2014		1,385
2015		1,188
2016		666
2017		500
Thereafter		968

	$	6,300

Rent expense under the Company’s operating leases was $0.6 million and $0.5 million for both the three months ended March 31, 2013 and 2012, respectively.

Litigation

From time to time, the Company is subject to various claims and legal proceedings, either asserted or unasserted, that arise in the ordinary course of business. The Company accrues for legal contingencies if the Company can estimate the potential liability and if the Company believes it is more likely than not that the case will be ruled against it. If a legal claim for which the Company did not accrue is resolved against it, the Company would record the expense in the period in which the ruling was made. The Company currently do not believe that the ultimate amount of liability, if any, for any pending claims of any type (alone or combined) will materially affect the Company’s financial position, results of operations or cash flows. The ultimate outcome of any litigation is uncertain, hover, and unfavorable outcomes could have a material negative impact on the Company’s financial condition and operating results. Regardless of outcome, litigation can have an adverse impact on us because of defense costs, negative publicity, diversion of management resources and other factors.

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint in the U.S. District Court for the Northern District of California against Source Photonics, Inc., MRV Communications, Inc., Oplink Communications, Inc. and the Company, or collectively, the co-defendants. In the complaint, Finisar alleged infringement of certain of its U.S. patents arising from the codefendants’ respective manufacture, importation, use, sale of or offer to sell certain optical transceiver products. Finisar sought to recover unspecified damages, up to treble the amount of actual damages, together with attorneys’ fees, interest and costs. Finisar alleged that at least some of the patents asserted are a part of certain digital diagnostic standards for optoelectronics transceivers, and, therefore, are being utilized in such digital diagnostic standards. On March 23, 2010, the Company filed an answer to the complaint and counterclaims, asserting two claims of patent infringement and additional claims asserting that Finisar has violated state and federal competition laws and violated its obligations to license on reasonable and non-discriminatory terms. On May 5, 2010, the court dismissed without prejudice all co-defendants (including the Company) except Source Photonics, Inc., on grounds that such claims should have been asserted in four separate lawsuits, one against each defendant. This dismissal without prejudice does not prevent Finisar from bringing a new similar lawsuit against the Company. The Company and Finisar had agreed to suspend their respective claims for a 90 day period and not to refile the originally asserted claims against each other until one or more specified events occur resulting in the partial or complete resolution of the litigation between Source Photonics and Finisar. On September 10, 2010, Source Photonics and Finisar settled their lawsuit, commencing the suspension period, which ended in December 2010. On January 18, 2011, the Company and Finisar again agreed to suspend their respective claims and not to refile the originally asserted claims against each other until at least 90 days after one or more specified events occur resulting in the partial or complete resolution of litigation involving the same Finisar patents between Oplink Communications, Inc. and Finisar. This tolling period expired on April 30, 2012. On May 3, 2012 the Company and Finisar agreed to further toll their respective claims until the refiling of certain of the previously asserted claims from this dispute. As a result, Finisar is permitted to bring a new lawsuit against the Company if it chooses to do so, and the Company may bring new claims against Finisar upon seven days written notice prior to filing such claims. The Company is currently unable to predict the outcome of this dispute and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Indemnifications

In the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations. As of March 31, 2013, the Company does not have any material indemnification claims that were probable or reasonably possible.

Purchase obligations

The Company has purchase obligations with certain suppliers for the purchase of goods and services entered in the ordinary course of business. As of March 31, 2013, total outstanding purchase obligations were $26.2 million, primarily due within the next 12 months.

Other contingencies

In connection with the Company’s acquisition of Santur that the Company completed in October 2011, the Company may be required to pay up to an additional $7.5 million in cash as further consideration for the business acquisition, contingent upon Santur’s gross profit performance during 2012. The fair value of the contingent consideration is re-measured each reporting period and any changes in the fair value of the contingent consideration are recognized as a gain or loss in the consolidated statements of operations. As of March 31, 2013 and December 31, 2012, the Company estimate the fair value of the contingent consideration was $1.0 million and $1.0 million, respectively. Although the Company believes the fair value of the contingent consideration is in accordance with the terms of the Santur acquisition agreements, the selling parties dispute the final amount to be paid. Any adjustment to the fair value of the contingent consideration may impact the results of operations in the period the adjustment is made.

Note 10. Stockholder’s equity

Common Stock

As of March 31, 2013, the Company had reserved the following shares of authorized but unissued common stock:


	Common Stock
Stock option plans		5,088,612
Stock purchase plan		257,734
Warrants		4,482

		5,350,828

Private Sale of Common Stock

On April 27, 2012, the Company issued and sold approximately 4.97 million shares of its common stock in a private placement transaction at a price of $8.00 per share for proceeds, net of offering costs of approximately $39.6 million. The shares of common stock are restricted from transfer pursuant to a lockup agreement for up to two years, at the end of which the Company is obligated to file one or more registration statements covering the potential resale of the shares of common stock. In connection with the private placement transactions, the Company agreed to use at least $30.0 million of the proceeds received to establish a wholly-owned subsidiary and facility in the Russian Federation for the benefit of the Company’s global organization. The Company has agreed to satisfy the performance obligations by July 31, 2014. In the event the Company has not recorded aggregate revenue from sales of its products in the Russian Federation of at least $26.8 million during the period beginning July 1, 2012 and ending June 30, 2014, then the date to achieve the performance obligations shall be extended from July 31, 2014 to March 31, 2015. If the Company fails to meet these performance obligations by the deadline, the Company will be required to pay $5.0 million.

The private placement transaction was recorded as an equity transaction. Of the common stock, $5.0 million is considered redeemable, as the Company may be required to pay this amount if it is unable to achieve its performance obligations by the date specified. While the Company intends to comply with its performance obligations, it has determined that some of these obligations are contingent upon government approval and maybe outside of the Company’s control. Therefore, the redeemable common stock is classified outside of equity on the Company’s consolidated balance sheet.

Equity Incentive Programs

The Company grants stock options, restricted stock units, stock appreciation units and stock purchase rights pursuant to stockholder and board approved equity incentive plans. These equity incentive plans are described in further detail in Note 12 of Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Cost of goods sold	$	79	$	61
Research and development		174		209
Sales and marketing		78		94
General and administrative		173		174

	$	504	$	538

The weighted-average fair value of options granted was $3.80 and $4.33 per share for the three months ended March 31, 2013 and 2012, respectively. At March 31, 2013, there was $3.1 million of unrecognized stock-based compensation expense that will be recognized over the remaining weighted-average period of 2.41 years.

The Company estimated the fair value of all employee stock options using a Black-Scholes valuation model with the following assumptions:


	Three months ended March 31,
Stock Options	2013			2012
Weighted-average expected term (years)		6.55			6.71
Weighted-average volatility		76	%		71	%
Risk-free interest rate		1.08	%		1.81	%
Expected dividends		0	%		0	%

Expected term. The expected term was estimated using the Company’s historical and expected future exercise behavior.

Volatility. Due to the limited history of the trading of the Company’s common stock since the initial public offering in February 2011, the expected volatility used by the Company is based on the actual volatility of similar entities. In evaluating similarity, factors such as industry, stage of life cycle, size, and financial leverage are taken into consideration. The term over which volatility was measured was commensurate with the expected term.

Risk-free interest rate. The risk-free rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term.

Expected dividends. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model.

The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods.

Stock appreciation units

Stock appreciation units are remeasured each period at fair value. The following table summarizes the expense (credit) recognized for stock appreciation units for the three months ended March 31, 2013 (in thousands):


	Three months ended March 31,
	2013			2012
Cost of goods sold	$	(24	)	$	(5	)
Research and development		(32	)		(9	)
Sales and marketing		(13	)		(4	)
General and administrative		(9	)		(3	)

	$	(78	)	$	(21	)

As of March 31, 2013 and December 31, 2012, the liabilities for the settlement of the stock appreciation units were $0.3 million and $0.4 million, respectively and were included in accrued and other current liabilities on the condensed consolidated balance sheet.

Based on the fair value of the stock appreciation units as of March 31, 2013, the Company had $0.05 million of unrecognized stock-based compensation expense that would be recognized over the remaining weighted-average period of 1.10 years. The Company estimated the fair value of all employee stock appreciation units using a Black-Scholes valuation model with the following assumptions:


	Three months ended March 31,
Stock appreciation units	2013	2012
Weighted-average expected term (years)	2.61	3.39
Weighted-average volatility	63%	69%
Risk-free interest rate	0.20 - 0.46%	0.42 - 1.04%
Expected dividends	0%	0%

Expected term. Vested stock appreciation units first become exercisable upon the expiration of the lock-up period associated with the initial public offering. Therefore, the Company estimated the term of the award based on an average of the weighted-average exercise period and the remaining contractual term.

Employee stock purchase plan (“ESPP”)

The following tables summarize the components of ESPP expense for the three months ended March 31, 2013 and 2012, respectively (in thousands):

The weighted-average fair value of restricted stock units granted was $5.74 and $6.10 per share for the three months ended March 31, 2013 and 2012, respectively. At March 31, 2013, the Company has $3.3 million of unrecognized stock-based compensation expense that will be recognized over the remaining weighted-average period of 1.92 years.

Note 12. Income taxes

The Company’s income tax expense for the three months ended March 31, 2013 is primarily related to income taxes of the Company’s non-U.S. operations. The Company recorded an income tax benefit of $596,000 and $60,000 for the three months ended March 31, 2013 and 2012, respectively.

(in thousands, except percentages)	2013		2012
Income tax benefit	$	596	$	60
Effective tax rate		6%		1%

The Company had an effective tax benefit rate of 6% in the three months ended March 31, 2013, compared with an effective tax benefit rate of 1% in the three months ended March 31, 2012. The Company’s income tax benefit was primarily due to recording a deferred tax asset arising from transaction costs related to the Company’s acquisition of OCU, partially offset by the operating profit realized in the Company’s foreign subsidiaries, and a loss before income taxes during the three months ended March 31, 2013. The Company’s income tax benefit incurred was primarily due to the loss before income taxes realized in the Company’s foreign subsidiaries during the three months ended March 31, 2012.

The Company conducts its business globally. However, operating income is subject to varying rates of tax in the United States, China and Japan. Consequently, the Company’s effective tax rate is dependent upon the geographic distribution of earnings or losses and the tax laws and regulations in each geographical region. The Company expects that its income taxes will vary in relation to the Company’s profitability and the geographic distribution of its profits. Historically, the Company has experienced net losses in the United States and in the short term, the Company expects this trend to continue. One of the Company’s subsidiaries in China generates a cash tax liability. The subsidiary has qualified for a preferential 15% tax rate available for high technology enterprises as opposed to the statutory 25% tax rate.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases using tax rates expected to be in effect during the years in which the basis differences reverse.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of a deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized. Due to historic losses in the U.S., the Company has a full valuation allowance on the U.S. federal and state deferred tax assets.

As of March 31, 2013, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2012.

Business overview

We are a leading designer and manufacturer of photonic integrated circuit, or PIC-based optoelectronic modules and subsystems for bandwidth-intensive, high-speed communications networks.

Our products are designed to enable high-speed transmission rates and efficient allocation of bandwidth over optical networks with high quality and low costs. Our PIC technology utilizes proprietary design elements that provide optical functionality on a silicon or indium phosphide or hybrid chip. PIC devices can integrate many more functional elements than discretely packaged components, enabling increased functionality in a small form factor while reducing packaging and interconnection costs. In addition, the cost advantages of PIC-based components are similar to the economics of semiconductor wafer mass manufacturing, where the marginal cost of producing an incremental chip is much less than that of a discrete component. We further design and produce certain high speed integrated circuits, or ICs, including gallium arsenide or GaAs ICs, that facilitate the high performance operation of optical components and related products.

We have research and development and wafer fabrication facilities in San Jose and Fremont, California which coordinate with our research and development and manufacturing facilities in Shenzhen and Wuhan, China, Tokyo, Japan, and Ottawa, Canada. We utilize proprietary design tools and design-for-manufacturing techniques to align our design process with our precision nanoscale, vertically integrated manufacturing and testing capabilities. We sell our products to the leading network equipment vendors globally, including ADVA AG Optical Networking Ltd., Alcatel-Lucent SA, Ciena Corporation, Cisco Systems, Inc., ECI Telecom Ltd., Telefonaktiebolaget LM Ericsson, FiberHome Technologies Group, Fujitsu Limited, Huawei Technologies Co., Ltd., Juniper Networks, Inc., Mitsubishi Electric Corporation, NEC Corporation, Nokia Siemens Networks B.V. and ZTE Corporation. We refer to these companies as our Tier 1 customers.

On April 27, 2012, we issued and sold approximately 4.97 million shares of our common stock in a private placement transaction at a price of $8.00 per share for gross proceeds of approximately $39.8 million. The shares of common stock are restricted from transfer pursuant to a lockup agreement for up to two years, at the end of which we are obligated to file one or more registration statements covering the potential resale of the shares of common stock. We intend to use a portion of the net proceeds from the sale of the shares of common stock for general corporate purposes and to establish a presence in the Russian Federation. In addition, we intend to establish a production facility in the Russian Federation, in accordance with the terms of a rights agreement entered into in connection with the private placement, for the benefit of the global organization. The expansion into the Russian Federation is targeted for completion by July 31, 2014.

On January 22, 2013, we signed a definitive agreement to acquire the optical semiconductor business unit of LAPIS Semiconductor Co., Ltd. (OCU). OCU is a leading provider of lasers, drivers, and detectors for high speed 100G applications located in Japan. This transaction was closed in March 2013. We believe the acquisition of OCU will serve to enhance our competitive position in 100G products.

In 2012, our revenue growth of 22% over the prior-year was driven primarily by increasing demand for our 40Gbps and 100Gbps speed products, which grew by over 300% over the prior year, as carriers continued to accelerate deployment of high capacity optical transport networks. We operated a sales model that focused on direct alignment with our customers through coordination of our sales, product engineering and manufacturing teams. Our sales and marketing organizations supported our strategy of increasing product penetration with our Tier 1 customers while also serving our broader customer base. We use a direct sales force in the U.S., China, Canada, Israel, Japan, the Russian Federation and the European Union. These individuals worked with our product engineers, and product marketing and sales operations teams, in an integrated approach to address our customers’ current and future needs. We also engaged independent commissioned representatives worldwide to extend our global reach.

For the first three months of fiscal 2013 compared to the same period in fiscal 2012, we continued to experience an increase in demand for our 100Gbps products as carriers continued to accelerate deployment of high capacity optical transport networks. This trend helped revenue from our Speed and Agility products to grow on a year over year basis. In the first quarter of 2013 demand for our Access products also declined relative to the same period in 2012 due to lower in fiber-to-the-home deployments in China and North America. The market for optical communications products remains highly competitive. We expect to continue to experience competition from companies that range from large international companies offering a wide range of products to smaller companies specializing in narrow markets. We anticipate macroeconomic conditions, including the slow recovery in the U.S., European sovereign debt issues, and a potential slowdown in the economic growth rate in China, could impact our results.

Critical accounting policies and estimates

There have been no material changes to our critical accounting policies and estimates during the three months ended March 31, 2013 from those disclosed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2012 Form 10-K.

Results of operations

Revenue

We sell substantially all of our products to original equipment manufacturers, or OEMs. Revenue is recognized upon delivery of our product to the OEM. We price our products based on market and competitive conditions and may periodically reduce the price of our products as market and competitive conditions change and as manufacturing costs are reduced. Our sales transactions to customers are denominated primarily in Chinese Renminbi (“RMB”) or U.S. dollars. For the three months ended March 31, 2013 and 2012, 33% and 46% of our sales were derived from our China-based subsidiaries, respectively. Revenue is driven by the volume of shipments and may be impacted by pricing pressures. We have generated most of our revenue from a limited number of customers. Given the high concentration of network equipment vendors in our industry, our top ten customers represented approximately 91% of our revenue in each of the three months ended March 31, 2013 and 2012.


	Three months ended March 31,
(in thousands)	2013		2012
Total revenue	$	56,063	$	54,223

Total revenue increased by $1.8 million in the three months ended March 31, 2013 compared to the three months ended March 31, 2012, representing a 3% increase. The increase in revenue was primarily attributable to growth in our speed and agility products as carriers increased deployment of 40 Gbps and 100 Gbps telecommunications networks, offset by decrease in demand for transceivers used in legacy networks at data rates at 10Gbps and below.

For the three months ended March 31, 2013, Huawei (27%), Ciena Corporation (22%), Alcatel-Lucent SA (13%) and Cisco (11%) each accounted for 10% or more of our total revenue. For the three months ended March 31, 2012, Huawei (36%), Ciena Corporation (14%) and Alcatel-Lucent SA (11%) each accounted for 10% or more of our total revenue. No other customers accounted for 10% or more of total revenue. We expect that a significant portion of our revenue will continue to be derived from a limited number of customers. As a result, the loss of, or a significant reduction in, orders from Huawei Technologies or any of our other key customers would materially and adversely affect our revenue and results of operations. We expect a significant portion of our sales to be denominated in foreign currencies in the future, and therefore may continue to be affected by changes in foreign exchange rates.

Cost of goods sold and gross margin

Our cost of goods sold consists primarily of the cost to produce wafers and to manufacture and test our products. We have a global set of suppliers to help balance considerations related to product availability, quality and cost. Some of our cost of goods sold are denominated primarily in RMB. Our manufacturing process extends from wafer fabrication through final module and subsystem assembly and test. The cost of our manufacturing, assembly and test processes includes the cost of personnel and the cost of our manufacturing equipment and facilities. Our cost of goods sold is impacted by manufacturing variances such as assembly and test yields and production volume. We typically experience lower yields and higher associated costs on new products. In general, our cost of goods sold associated with a particular product declines over time as a result of decreases in wafer costs associated with the increase in the volume of wafers produced, as well as yield improvements and assembly and test enhancements. Additionally, our cost of goods sold includes stock-based compensation, reserves for excess and obsolete inventory, royalty payments, amortization of certain purchased intangible assets and acquisition-related fair value adjustments, warranty, shipping and allocated facilities costs.

Gross profit as a percentage of total revenue, or gross margin, has been and is expected to continue to be affected by a variety of factors, including the introduction of new products, production volume, production volume compared to sales over time, the mix of products sold, inventory changes, changes in the average selling prices of our products, changes in the cost and volumes of materials purchased from our suppliers, changes in labor costs, changes in overhead costs or requirements, revaluation of stock appreciation unit awards that are impacted by our stock price, and any reserves for excess and obsolete inventories. Our newer and more advanced products typically have higher average selling prices and higher gross margins. Average selling prices by product typically decline as a result of periodic negotiations with our customers and competitive pressures. We strive to increase our gross margin as we seek to manage the costs of our supply chain and increase productivity in our manufacturing processes.

	Three months ended March 31,
	2013			2012
Gross margin		21	%		21	%

Cost of goods sold increased by $1.5 million in the three months ended March 31, 2013 compared to the three months ended March 31, 2012, representing a 4% increase. The slight increase in cost of goods sold for the three months ended March 31, 2013 compared to the same quarter of 2012 was mainly driven by higher sales. Gross margin remained relatively flat for the three months ended March 31, 2013, compared to the three months ended March 31, 2012.

We may experience higher China manufacturing labor cost due to future labor or other laws and regulations in China, and our gross margins and results of operations may be adversely affected.

Operating expenses

Our operating expenses consist of research and development, sales and marketing, general and administrative, amortization of purchased intangible assets, and adjustment to the fair value of contingent consideration. Personnel costs are the most significant component of operating expenses and consist of costs such as salaries, benefits, bonuses, stock-based compensation and, with regard to sales and marketing expense, sales commissions. Our operating expenses are denominated primarily in RMB and U.S. dollars.

Restructuring charges		325		1	%		130		0	%

Total operating expenses	$	22,484		40	%	$	22,947		42	%

Research and development

Research and development expense consists of personnel costs, including stock-based compensation, for our research and development personnel, and product development costs, including engineering services, development software and hardware tools, depreciation of capital equipment and facility costs. We record all research and development expense as incurred.

Research and development expense decreased by $0.8 million in the three months ended March 31, 2013 compared to the three months ended March 31, 2012, representing an 8% decrease. This decrease was primarily due to a $0.5 million lower payroll and employee-related costs in 2013, due to our integration of Santur, and a $0.3 million decrease due to lower material consumption from research and development projects.

We intend to continue to invest in research and development and expect this expense to increase as we grow our business. As a percentage of total revenue, our research and development expense may vary as our revenue changes over time.

Sales and marketing

Sales and marketing expense consists primarily of personnel costs, including stock-based compensation and sales commissions, costs related to sales and marketing programs and services and facility costs.

Sales and marketing expense increased by $0.6 million in the three months ended March 31, 2013 compared to the three months ended March 31, 2012, representing an 19% increases. This increase was primarily due to a $0.3 million increase in additional payroll and employee-related costs to support sales growth and a $0.2 million increase in allowance for doubtful account reserve.

We expect our sales and marketing expense to increase as a result of the acquisition of OCU and as we grow our business, expand our marketing activities, increase the number of sales and marketing professionals and incur employee-related costs accordingly. As a percentage of total revenue, our sales and marketing expense may vary as our revenue changes over time.

General and administrative

General and administrative expense consists primarily of personnel costs, including stock-based compensation, for our finance, legal, human resources and information technology personnel and certain executive officers, as well as professional services costs related to accounting, tax, banking, legal and information technology services, depreciation of capital equipment, facility costs and restructuring charges.

General and administrative expense increased by $1.6 million in the three months ended March 31, 2013 compared to the three months ended March 31, 2012, representing a 22% increase. This was primarily due to a $3.2 million increase in acquisition-related cost for OCU, offset by a $1.0 million decrease in payroll and employee-related costs and a $0.6 million decrease in professional fees.

We expect our general and administrative expense to increase as a result of the acquisition of OCU and as we expand and grow our operations and business. As a percentage of total revenue, our general and administrative expense may vary as our revenue changes over time.

Amortization of purchased intangible assets

We completed a series of business acquisitions in 2005 and 2006 and, more recently, in the fourth quarter of 2011 and in the first quarter of 2013, which included the acquisition of intangible assets. These intangible assets are being amortized over their estimated useful lives. Amortization expense relating to technology and patents and leasehold interests are includes within cost of goods sold, while customer relationships and noncompete agreements are recorded within operating expenses.

Amortization of purchased intangible assets decreased by 9% in the three months ended March 31, 2013 compared to the three months ended March 31, 2012. The decrease was primarily due to lower amortization from fully amortized assets associated with the acquisitions completed in 2005 and 2006. Amortization of purchased intangible related to our acquisition of OCU will be amortized beginning in the second quarter of 2013. Please refer to note 6. Business Combination of our Notes to Condensed Consolidated Financial Statements for details.

Adjustment to the fair value of contingent consideration

In connection with our acquisition of Santur Corporation (“Santur”) in October 2011, we may be required to pay up to an additional $7.5 million in cash as further consideration for the business acquisition, contingent upon Santur’s gross profit performance during 2012. The fair value of the contingent consideration is re-measured each reporting period and any changes in the fair value of the contingent consideration are recognized as a gain or loss in the consolidated statements of operations. During the three months ended March 31, 2013 and 2012, we recorded adjustments to the fair value of the consideration of $0.0 million and $1.9 million, respectively. As of March 31, 2013 and December 31, 2012, the fair value of the contingent consideration was $1.0 million. Although we believe the fair value of the contingent consideration is in accordance with the terms of the Santur acquisition agreements, the selling parties disputes the final amount to be paid. Any adjustments to the fair value of the contingent consideration may impact the result of operations in the period the adjustment is made.

Purchase Price Allocation

We accounted for our acquisition of the OCU assets and assumed liabilities using the acquisition method of accounting for business combinations. The OCU’s tangible and identifiable intangible assets acquired and liabilities assumed were recorded based upon their estimated fair values as of the closing date of the acquisition. The excess of purchase price over the value of the net assets acquired was recorded as goodwill. Our purchase price allocation is preliminary. The fair values of acquired assets and liabilities may be further adjusted as additional information becomes available during the allocation period. Additional information that may become available subsequently and may result in changes in the values allocated to various assets and liabilities includes, but is not limited to, pension and retirement liabilities, asset retirement obligations, inventory fair value, working capital adjustments to be agreed with the Lapis. Any changes in the values allocated to tangible and specifically identified intangible assets acquired and liabilities assumed during the allocation period may result in material adjustments to goodwill. Please refer to Note 6.

Restructuring charges

In the first quarter of 2013, we exited and closed one facility at our headquarters location to align our facilities usage with our current size. As a result, we recorded a restructuring charge related to the facility impairment of approximately $0.3 million including $0.1 million wrote off on deferred rent. As of March 31, 2013, the remaining balance on this restructuring obligation was $0.4 million, which we expect to pay through 2015.

Interest and other expense, net

Interest income consists of income earned on our cash, cash equivalents and short-term investments. Interest expense consists of amounts paid for interest on our short-term and long-term debt borrowings. Other income (expense), net is primarily made up of government subsidies, and foreign currency transaction gains and losses. The functional currency of our subsidiaries in China is the RMB and the foreign currency transaction gains and losses of our subsidiaries in China primarily result from their transactions in U.S. dollars.


	Three months ended March 31,
(in thousands)	2013			2012
Interest income	$	131		$	132
Interest expense		(163	)		(154	)
Other expense, net		(274	)		(275	)

Total	$	(306	)	$	(297	)

Total interest and other expense, net remained relatively flat in the three months ended March 31, 2013 compared to the three months ended March 31, 2012. We expect our interest income to remain relatively modest given the low yields available in the marketplace and lower investable balances. And we expect our interest expense to increase due to additional borrowings. Please refer to note 8. Debt of our Notes to Condensed Consolidated Financial Statements for details.

Income taxes

We conduct our business globally. Therefore, our operating income is subject to varying rates of tax in the United States, China, Japan and other various foreign jurisdictions. Consequently, our effective tax rate is dependent upon the geographic distribution of our earnings or losses and the tax laws and regulations in each geographical region. We expect that our income taxes will vary in relation to our profitability and the geographic distribution of our profits. Historically, we have experienced net losses in the U.S. and in the short term, we expect this trend to continue. In China, one of our subsidiaries has qualified for a preferential 15% tax rate available for high technology enterprises as opposed to the statutory 25% tax rate. The preferential rate applies from 2010 to 2013. The preferential rate applied to 2013 have been approved to remain at 15% through 2014.


	Three months ended March 31,
(in thousands, except percentages)	2013			2012
Income tax benefit	$	596		$	60
Effective tax rate		6	%		1	%

We had an effective tax benefit rate of 6% in the three months ended March 31, 2013, compared with an effective tax benefit rate of 1% in the three months ended March 31, 2012. Our income tax benefit was primarily due to recording a deferred tax asset arising from transaction costs related to our acquisition of OCU, partially offset by the operating profit realized in our foreign subsidiaries, and a consolidated loss before income taxes during the three months ended March 31, 2013. Our income tax benefit incurred was primarily due to the loss before income taxes realized in our foreign subsidiaries during the three months ended March 31, 2012.

Liquidity and capital resources

We have financed our operations through issuances of investment securities and cash generated from operations and from various lending arrangements. At March 31, 2013, our cash and cash equivalents totaled $51.4 million, and our short-term investments totaled $48.4 million. Cash and cash equivalents were held for working capital purposes and were invested primarily in money market funds. We do not enter into investments for trading or speculative purposes.

On April 27, 2012, we issued and sold approximately 4.97 million shares of our common stock in a private placement transaction at a price of $8.00 per share for gross proceeds of approximately $39.8 million. The shares of common stock are restricted from transfer pursuant to a lockup agreement for up to two years, at the end of which we are obligated to file one or more registration statements covering the potential resale of the shares of common stock. We intend to use a portion of the net proceeds from the sale of the shares of common stock for general corporate purposes and to establish a design center in the Russian Federation. In addition, we will establish a production facility in the Russian Federation, in accordance with the terms of a rights agreement entered into in connection with the private placement, for the benefit of the global organization. The expansion into the Russian Federation is targeted for completion by July 31, 2014, and is not expected to have a material impact on our results of operations in 2013.

We believe that our existing cash and cash equivalents, and cash flows from our operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced products, the costs to increase our manufacturing capacity, the continuing market acceptance of our products and acquisitions of businesses and technology. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition would be adversely affected.

A customary business practice in China is for customers to exchange our accounts receivable with notes receivable issued by their bank. From time to time we accept notes receivable from certain of our customers in China. These notes receivable are non-interest bearing and are generally due within six months, and such notes receivable may be redeemed with the issuing bank prior to maturity at a discount. Historically, we have collected on the notes receivable in full at the time of maturity.

Frequently, we also direct our banking partners to issue notes payable to our suppliers in China in exchange for accounts payable. Our Chinese subsidiaries’ banks issue the notes to vendors and issue payment to the vendors upon redemption. We owe the payable balance to the issuing bank. The notes payable are non-interest bearing and are generally due within six months of issuance. As a condition of the notes payable lending arrangements, we are required to keep a compensating balance at the issuing banks that is a percentage of the total notes payable balance until the notes payable are paid by our subsidiaries in China. These balances are classified as restricted cash on our consolidated balance sheets. As of March 31, 2013, our restricted cash totaled $2.1 million.

•

As of December 31, 2012, $14.2 million was outstanding under the acquisition advance and $5.8 million was available for borrowing. The advances bear interest at a rate of LIBOR plus 2%.

On March 21, 2013, we amended and restated in our entirety Loan and Security Agreement with the same bank and added East-West Bank as a lender. The components of the available credit facilities as of March 31, 2013 as follows:

•

Our U.S. loan and security agreement requires us to maintain specified financial covenants, including a liquidity ratio, restricts our ability to incur additional debt or to engage in specified transactions and is secured by substantially all of our U.S. assets, other than intellectual property assets. As of March 31, 2013, we were in compliance with the covenants contained in this agreement.

Our subsidiaries in China have short-term line of credit facilities with several banking institutions. These short-term loans have an original maturity date of one year or less as of March 31, 2013. Amounts requested by us are not guaranteed and are subject to the banks’ funds and currency availability. The short-term loan agreements do not contain financial covenants. As of March 31, 2013, we had no short-term loans outstanding.

The table below sets forth selected cash flow data for the periods presented:

Operating activities

During the three months ended March 31, 2013, net cash provided by operating activities was $2.8 million. Cash provided by operating activities was primarily related to cash payments to our employees and suppliers in excess of cash receipts from customers. We recognized a net loss of $10.5 million during the three months ended March 31, 2013. This net loss incorporated non-cash charges, including depreciation and amortization of $4.6 million, stock-based compensation expenses of $1.2 million, and loss on disposal of property and equipment of $0.1 million. During the three months ended March 31, 2013, there was an increase in accounts payable of $5.1 million, an increase of $3.2 million in acquisition-related costs of OCU, and a decrease of $7.2 million in accounts receivable due to improved collection efforts. These amounts were partially offset by the purchase of inventory of $4.7 million to replenish our inventories in preparation for higher customer demand in future periods, a net decrease in accrued and other liabilities of $1.5 million, and an increase in prepaid expenses and other current assets of $1.3 million during the period.

During the three months ended March 31, 2012, net cash used in operating activities was $1.6 million. Cash used in operating activities was primarily related to cash payments to our employees and suppliers in excess of cash receipts from customers. During the three months ended March 31, 2012, we recognized a net loss of $11.6 million. This net loss incorporated non-cash charges, including depreciation and amortization of $5.4 million, stock-based compensation expenses of $1.1 million, non-cash increases to our asset reserve accounts of $0.7 million, partially offset by $0.8 million gain on sale of Shenzhen Photon Broadband Technology Co., Ltd. (“Broadband”), a China subsidiary. During the three months ended March 31, 2012, there was a decrease of $9.2 million in accounts receivable due to improved collection efforts. These amounts were partially offset by the purchase of inventory of $4.7 million to replenish our inventories in preparation for higher customer demand in future periods, and the net increase in prepaid expenses and other current assets of $1.8 million during the period.

Investing activities

Our investing activities consisted primarily of purchases and sales of investments and capital expenditures.

During the three months ended March 31, 2013, net cash provided by investing activities was $4.7 million. We received $44.6 million for the sale and maturity of investment securities, which was offset by $14.6 million of cash used for the acquisition of OCU, $29.0 million for the purchase of investment securities, and $6.2 million in capital expenditures.

During the three months ended March 31, 2012, net cash provided by investing activities was $7.1 million. We received $20.2 million for the sale and maturity of investment securities and $1.8 million for the sale of Broadband, which was partially offset by $13.0 million of cash used for the purchase of investment securities and $2.0 million of capital expenditures.

Financing activities

Our financing activities consisted primarily of proceeds from the issuance of stock and activity associated with our various lending arrangements.

During the three months ended March 31, 2013, net cash provided from financing activities was $16.3 million. We received $40.0 million in proceeds from bank loans and $4.9 million from the issuance of notes payable, which was offset by $22.2 million used for the repayment of bank loans, and $6.5 million for the repayment of notes payables.

During the three months ended March 31, 2012, net cash used in financing activities was $1.3 million. We used $1.3 million of cash for the repayment of bank loans, and $0.1 million for the repayment of notes payable, net of proceeds.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate fluctuation risk

Our cash equivalents consisted primarily of money market funds and interest and non-interest bearing bank deposits. The main objective of these instruments was safety of principal and liquidity while maximizing return, without significantly increasing risk. Given the short-term nature of our cash equivalents, we do not anticipate any material effect on our portfolio due to fluctuations in interest rates.

We started to invest our excess cash in short-term and long-term marketable securities in 2011 to take advantage of higher yields generated by these investments. As of March 31, 2013, the gross unrealized gains or losses on our investments classified as available-for-sale were primarily due to increases or decreases in the fair value of the marketable securities as a result of changes in market interest rates. We have determined that the gross unrealized gains or losses on the available-for-sale securities at March 31, 2013 are temporary in nature. We may sell these marketable securities investments in the future to fund future operating needs. As a result, we recorded all our marketable securities in short-term investments as of March 31, 2013, regardless of the contractual maturity date of the securities.

We are exposed to market risk due to the possibility of changing interest rates associated with certain outstanding balances under our debt instruments. As of March 31, 2013, we did not have outstanding debt in China. As of March 31, 2013, our U.S. debt was based on floating rates of interest and is subject to fluctuations in interest rates. As of March 31, 2012, the interest rates on all of our outstanding debt in China were fixed at the time of drawdown, and were not subject to fluctuations. As of March 31, 2012, we did not have outstanding debt in U.S. As of March 31, 2013 and 2012, we had not hedged our interest rate risk.

Foreign currency exchange risk

Foreign currency exchange rates are subject to fluctuation and may cause us to recognize transaction gains and losses in our statement of operations. A substantial portion of our business is conducted through our subsidiaries in China whose functional currency is the RMB. To the extent that transactions by our subsidiaries in China are denominated in currencies other than RMB, we bear the risk that fluctuations in the exchange rates of the RMB in relation to other currencies could decrease our revenue and increase our costs and expenses. During the three months ended March 31, 2013 and 2012, we recognized foreign currency transaction losses of $232,000 and $204,000, respectively. We use the U.S. dollar as the reporting currency for our consolidated financial statements. Any significant revaluation of the RMB may materially and adversely affect our results of operations upon translation of our Chinese subsidiaries’ financial statements into U.S. dollars. While we generate a significant of our revenue in RMB, a significant of our operating expenses are in U.S. dollars. Therefore depreciation in RMB against the U.S. dollar would negatively impact our revenue upon translation to the U.S. dollars but the impact on operating expenses would be less. For example, for the three months ended March 31, 2013, a 10% depreciation in RMB against the U.S. dollar would have resulted in a $1.7 million decrease in our revenue and a $0.1 million increase in our net loss for the period. Comparatively, for the three months ended March 31, 2012, a 10% depreciation in RMB against the U.S. dollar would have resulted in a $2.3 million decrease in our revenue and a $0.1 million increase in our net loss for the period.

In connection with the OCU acquisition in the first quarter of 2013, we recorded a notes payable of $11.1 million. The payment is denominated in Japanese Yen. Any currency fluctuations may impact on our results of operations in the period a payment is made.

To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedging transactions may be limited and we may not be able to successfully hedge our exposure. In addition, our currency exchange variations may be magnified by any Chinese exchange control regulations that restrict our ability to convert RMB into another foreign currency.

Inflation risk

Inflationary factors, such as increases in our cost of goods sold and operating expenses, may adversely affect our results of operations. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, an increase in the rate of inflation in the future, particularly in China, may have an adverse affect on our levels of gross profit and operating expenses as a percentage of revenue if the sales prices for our products do not proportionately increase with these increased expenses.

ITEM 4.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2013. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this report, our disclosure controls and procedures were not effective as a result of the material weakness that existed in our internal control over financial reporting.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control over Financial Reporting

As previously reported in our Annual Report on Form 10-K, as of December 31, 2012, our management concluded that we did not maintain effective internal control over financial reporting as of December 31, 2012, because of the material weakness described in our Annual Report on Form 10-K, specifically our internal controls over annual inventory counts did not operate effectively to provide reasonable assurance that all inventory count results were reconciled to our accounting records.

In response to the material weakness identified, in the fiscal quarter ended March 31, 2013, we instituted several new internal controls in order to remediate the weakness:

•

inventory control and annual physical count training program for relevant personnel specifically focusing on material located in the income/receiving areas; and

•

performing more frequent inventory cycle and physical counts at our Fremont and San Jose, California facilities.

We believe these additional internal controls will be effective in remediating the material weakness described above. As we continue to evaluate and work to improve our internal control over financial reporting, management may determine to take additional measures to address the material weakness or determine to modify the remediation plan described above.

Other than the changes described above there was no significant change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation described above that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.

LEGAL PROCEEDINGS

From time to time, we are involved in litigation that we believe is of the type common to companies engaged in our line of business, including commercial disputes and employment issues. As of the date of this Quarterly Report on Form 10-Q, other than as described below, we are not involved in any pending legal proceedings that we believe could have a material adverse effect on our financial condition, results of operations or cash flows. However, as described below, a certain dispute involves a claim by a third party that our activities infringe their intellectual property rights. This and other types of intellectual property rights claims generally involve the demand by a third party that we cease the manufacture, use or sale of the allegedly infringing products, processes or technologies and/or pay substantial damages or royalties for past, present and future use of the allegedly infringing intellectual property. Claims that our products or processes infringe or misappropriate any third-party intellectual property rights (including claims arising through our contractual indemnification of our customers) often involve highly complex, technical issues, the outcome of which is inherently uncertain. Moreover, from time to time, we may pursue litigation to assert our intellectual property rights. Regardless of the merit or resolution of any such litigation, complex intellectual property litigation is generally costly and diverts the efforts and attention of our management and technical personnel which could adversely affect our business.

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint in the U.S. District Court for the Northern District of California against Source Photonics, Inc., MRV Communications, Inc., Oplink Communications, Inc. and us, or collectively, the co-defendants. In the complaint, Finisar alleged infringement of certain of its U.S. patents arising from the codefendants’ respective manufacture, importation, use, sale of or offer to sell certain optical transceiver products. Finisar sought to recover unspecified damages, up to treble the amount of actual damages, together with attorneys’ fees, interest and costs. Finisar alleged that at least some of the patents asserted are a part of certain digital diagnostic standards for optoelectronics transceivers, and, therefore, are being utilized in such digital diagnostic standards. On March 23, 2010, we filed an answer to the complaint and counterclaims, asserting two claims of patent infringement and additional claims asserting that Finisar has violated state and federal competition laws and violated our obligations to license on reasonable and non-discriminatory terms. On May 5, 2010, the court dismissed without prejudice all co-defendants (including us) except Source Photonics, Inc., on grounds that such claims should have been asserted in four separate lawsuits, one against each defendant. This dismissal without prejudice does not prevent Finisar from bringing a new similar lawsuit against us. We and Finisar had agreed to suspend our respective claims for a 90 day period and not to refile the originally asserted claims against each other until one or more specified events occur resulting in the partial or complete resolution of the litigation between Source Photonics and Finisar. On September 10, 2010, Source Photonics and Finisar settled their lawsuit, commencing the suspension period, which ended in December 2010. On January 18, 2011, we and Finisar again agreed to suspend our respective claims and not to refile the originally asserted claims against each other until at least 90 days after one or more specified events occur resulting in the partial or complete resolution of litigation involving the same Finisar patents between Oplink Communications, Inc. and Finisar. This tolling period expired on April 30, 2012. On May 3, 2012 we and Finisar agreed to further toll our respective claims until the refiling of certain of the previously asserted claims from this dispute. As a result, Finisar is permitted to bring a new lawsuit against us if it chooses to do so, and we may bring new claims against Finisar upon seven days written notice prior to filing such claims.

ITEM 1A. RISK FACTORS

The risk factors facing our company have not changed materially from those set forth in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the SEC on March 15, 2013, which risk factors are set forth below, except for those risk factors denoted by an asterisk (*).

Risks related to our business

*We have a history of losses which may continue in the future.

We have a history of losses and we may incur additional losses in future periods. As of March 31, 2013, our accumulated deficit was $258.5 million. We also expect to continue to make significant expenditures related to the development of our business. These include expenditures to hire additional personnel related to the sales, marketing and development of our products and to maintain and expand our manufacturing facilities and research and development operations.

We have entered into lending arrangements that provide for some of the capital necessary to develop our business further and these lending arrangements contain various restrictions and financial covenants, including a covenant not to exceed a maximum ration of funded debt to adjusted EBITDA on a quarterly basis. Significant additional losses in future period could cause us to breach these covenants. A breach of any of these covenants or a failure to pay interest or indebtedness when due under any of these lending arrangements, could result in a variety of material adverse consequences.

Customer demand is difficult to accurately forecast and, as a result, we may be unable to optimally match production with customer demand, which could adversely affect our business and financial results.

We make planning and spending decisions, including determining the levels of business that we will seek and accept, production schedules, and inventory levels, component procurement commitments, personnel needs and other resource requirements, based on our estimates of customer requirements. The short-term nature of commitments by many of our customers and the possibility of unexpected changes in demand for their products reduce our ability to accurately estimate future customer requirements. On occasion, customers may require rapid increases in production, which can strain our resources, cause our manufacturing to be negatively impacted by materials shortages, necessitate higher or more restrictive procurement commitments, increase our manufacturing yield loss and scrapping of excess materials, and reduce our gross margin. We may not have sufficient capacity at any given time to meet the volume demands of our customers, or one or more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. Conversely, a downturn in the markets in which our customers compete can cause, and in the past have caused, our customers to significantly reduce or delay the amount of products ordered from us or to cancel existing orders, leading to lower utilization of our facilities. Because many of our costs and operating expenses are relatively fixed, reduction in customer demand due to market downturns or other reasons would have a material adverse effect on our gross margin, operating income and cash flow. For example, in the fourth quarter of 2012, we experienced an increase in manufacturing costs for one of our high speed products and separately, lower utilization of one of our water fabrication facilities, which adversely affected our gross margin in the fourth quarter of 2012 and first quarter of 2013. We expect these impacts to continue into the second quarter of 2013, which is expected to adversely affect our gross margins for the quarters.

Our products are typically sold pursuant to individual purchase orders or by use of a vendor-managed inventory, or VMI, model, which is a process by which we ship agreed quantities of products to a customer-designated location and those products remain our inventory and we retain the title and risk of loss for those products until the customer takes possession of the products. While our customers generally provide us with their demand forecasts and may give us a promised market share award, they are typically not contractually committed to buy any quantity of products beyond firm purchase orders. Many of our customers may increase, decrease, cancel or delay purchase orders already in place. We have experienced and expect to continue to experience wide fluctuations in demand from customers using VMI, particularly Huawei Technologies, even in instances where we have built and shipped products to the customer-designated locations as VMI. In 2012, there was an increase in the number of our customers utilizing VMI, which may increase our exposure to risks of wide fluctuations in demand from VMI customer locations. If any of our major customers decrease, stop or delay purchasing our products for any reason, our business and results of operations would be harmed. Cancellation or delays of such orders may cause us to incur an adverse effect on our revenues, as well as adversely affect our overall results of operations

We are dependent on Huawei Technologies and our other key customers for a significant portion of our revenue and the loss of, or a significant reduction in orders from, Huawei Technologies or any of our other key customers may reduce our revenue and adversely impact our results of operations.

Historically, we have generated most of our revenue from a limited number of customers. In 2012, our largest customer, Huawei Technologies, represented 35.8% of our total revenue and our top ten customers represented 90.2% of our total revenue. As a result, the loss of, or a significant reduction in orders from Huawei Technologies or any of our other key customers would materially and adversely affect our revenue and results of operations. For instance, in the three months ended September 30, 2011, demand from Huawei Technologies was lower than expected, which adversely affected our revenue for such period. Adverse events affecting our customers could also adversely affect our revenue and results of operations (for instance, in 2009, the filing of a voluntary petition for bankruptcy protection by one of our customers, Nortel Networks Limited, prevented us from timely collection of our accounts receivable from that customer). In addition, network equipment vendors serving the communications networks industry may continue to consolidate, and we may not be able to offset any potential decline in revenue arising from consolidation of our existing customers with revenue from new customers.

We are under continuous pressure to reduce the prices of our products, which may adversely affect our gross margins.

The communications networks industry has been characterized by declining product prices over time. We have reduced the prices of many of our products in the past and we expect to continue to experience pricing pressure for our products in the future, including from our major customers. When seeking to maintain or increase their market share, our competitors may also reduce the prices of their products. In addition, our customers may have the ability or seek to internally develop and manufacture competing products at a lower cost than we would otherwise charge, which would add additional pressure on us to lower our selling prices. If we are unable to offset any future reductions in our average selling prices by increasing our sales volume, reducing our costs and expenses or introducing new products, our gross margin would suffer.

Increasing costs may adversely impact our gross margins.

The rate of increase in our costs and expenses, including as a result of rising labor costs in China, may exceed the rate of increase in our revenue, either of which would materially and adversely affect our business, our results of operations and our financial condition.

We are subject to the cyclical nature of the markets in which we compete and any future downturn may reduce demand for our products and revenue.

The markets in which we compete are tied to the aggregate capital expenditures of service providers as they build out and upgrade their network infrastructure. These markets are highly cyclical and characterized by constant and rapid technological change, price erosion, evolving standards and wide fluctuations in product supply and demand. In the past, including recently to varying degrees in China, the U.S. and Europe, these markets have experienced significant downturns, often connected with, or in anticipation of, the maturation of product cycles—for both manufacturers’ and their customers’ products—or in response to over or under purchasing of inventory by our customers relative to ultimate carrier demand, and with declining general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices.

Our historical results of operations have been subject to substantial fluctuations, and we may experience substantial period-to-period fluctuations in future results of operations. Any future downturn in the markets in which we compete could significantly reduce the demand for our products and therefore may result in a significant reduction in revenue. It may also increase the volatility of the price of our common stock. Our revenue and results of operations may be materially and adversely affected in the future due to changes in demand from individual customers or cyclical changes in the markets utilizing our products.

In addition, the communications networks industry from time to time has experienced and may again experience a pronounced downturn. To respond to a downturn, many service providers may slow their capital expenditures, cancel or delay new developments, reduce their workforces and inventories and take a cautious approach to acquiring new equipment and technologies from original equipment manufacturers, which would have a negative impact on our business. Weakness in the global economy or a future downturn in the communications networks industry may cause our results of operations to fluctuate from quarter-to-quarter and year-to-year, harm our business, and may increase the volatility of the price of our common stock.

It could be discovered that our products contain defects that may cause us to incur significant costs, divert our attention, result in a loss of customers and result in product liability claims.

Our products are complex and undergo quality testing as well as formal qualification, both by our customers and by us. However, defects may occur from time to time. Our customers’ testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios and over varying amounts of time. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing or other unforeseen reasons. As a result, we could incur significant costs to repair or replace defective products under warranty, particularly when such failures occur in installed systems. We have experienced such failures in the past and will continue to face this risk going forward, as our products are widely deployed throughout the world in multiple demanding environments and applications. In addition, we may in certain circumstances honor warranty claims after the warranty has expired or for problems not covered by warranty in order to maintain customer relationships. Any significant product failure could result in lost future sales of the affected product and other products, as well as customer relations problems, litigation and damage to our reputation.

In addition, our products are typically embedded in, or deployed in conjunction with, our customers’ products, which incorporate a variety of components, modules and subsystems and may be expected to interoperate with modules produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages or warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems or loss of customers, all of which would harm our business.

The occurrence of any defects in our products could give rise to liability for damages caused by such defects. They could, moreover, impair our customers’ acceptance of our products. Both could have a material adverse effect on our business and financial condition. Although we carry product liability insurance which covers this risk, this insurance may not adequately cover our costs arising from defects in our products or otherwise.

If spending for communications networks does not continue to grow as expected, our business and financial results may suffer.

Our future success as a provider of modules and subsystems to leading network equipment vendors depends on their continued capital spending on global communications networks. Network traffic has experienced rapid growth driven primarily by bandwidth-intensive content, including mobile video and data services, HD and 3D video, music, social networking, video conferencing and other multimedia. This growth is intensified by the proliferation of fixed and wireless network-attached devices, including smartphones, laptops, netbooks, tablet computers, PCs, e-readers, televisions and gaming devices that are enabling consumers to access content at increasing data rates anytime and anywhere. Our future success depends on continued demand for high-bandwidth, high-speed communications networks and the ability of network equipment vendors to meet this demand. Growth in demand for communications networks is limited by several factors, including an evolving regulatory environment and uncertainty regarding long-term sustainable business models. We cannot be certain that demand for bandwidth-intensive content will continue to grow in the future. If expectations for growth of communications networks and bandwidth consumption are not realized and investment in communications networks does not grow as anticipated, our business could be harmed.

Manufacturing problems could result in delays in product shipments to customers and could adversely affect our revenue, competitive position and reputation.

We may experience delays, disruptions or quality control problems in our manufacturing operations. For instance, we could experience a disruption in our fabrication facilities for our PIC products due to any number of reasons, such as equipment failure, contaminated materials or process deviations, which could adversely impact manufacturing yields or delay product shipments. As a result, we could incur additional costs that would adversely affect our gross margin, and product shipments to our customers could be delayed beyond the shipment schedules requested by our customers, which would negatively affect our revenue, competitive position and reputation.

Additionally, manufacturing yields depend on a number of factors, including the stability and manufacturability of the product design, manufacturing improvements gained over cumulative production volumes, the quality and consistency of component parts and the nature and extent of customization requirements by customers. Capacity constraints, raw materials shortages, logistics issues, labor shortages, the introduction of new product lines, rapid increases in production demands and changes in customer requirements, manufacturing facilities or processes, or those of some third party contract manufacturers and suppliers of raw materials and components have historically caused, and may in the future cause, reduced manufacturing yields, negatively impacting the gross margin on, and our production capacity for, those products. Moreover, an increase in the rejection and rework rate of products during the quality control process before, during or after manufacture would result in our experiencing lower yields, gross margin and production capacity. Our ability to maintain sufficient manufacturing yields is particularly challenging with respect to PICs due to the complexity and required precision of a large number of unique manufacturing process steps. Manufacturing yields for PICs can also suffer if contaminated materials or materials that do not meet highly precise composition requirements are inadvertently utilized. Because a large portion of our PIC manufacturing costs are fixed, PIC manufacturing yields have a substantial effect on our gross margin. Lower than expected manufacturing yields could also delay product shipments and decrease our revenue. It can be hard to cost-effectively increase our production output rapidly, and we can experience yield loss and excess material scrap, which can increase our cost of goods sold and harm our profitability. Also, if we do not have sufficient demand for our PIC-based products our cost of goods sold can increase as the fixed costs of our fabrication facilities are spread over lower production. For example, in the fourth quarter of 2012, we experienced such increased costs with one of our high speed products and one of our wafer fabrication facilities. These higher costs continued in the first quarter of 2013 and are expected to continue through the second quarter of 2013, and could re-occur due to these or other reasons, in the future.

We depend upon outside contract manufacturers for a portion of the manufacturing process for some of our products. Our operations and revenue related to these products could be adversely affected if we encounter problems with this contract manufacturer.

Almost all of our other products are manufactured internally. However we also rely upon contract manufacturer in Malaysia and Japan to produce the finished portion of a few of our products. Our reliance on a contract manufacturer for these products makes us vulnerable to possible capacity constraints and reduced control over delivery schedules, manufacturing yields, manufacturing quality/controls and costs. For instance, recently one of our contract manufacturers has been unable to meet all of our customer demand in a timely fashion. Although we have not experienced any adverse impact from these delays, if these issues continue, they could have a material adverse effect on the revenue from our products. If the contract manufacturer for one of our product were unable or unwilling to manufacture our products in required volumes and at high quality levels or to continue our existing supply arrangement, we would have to identify, qualify and select an acceptable alternative contract manufacturer or move these manufacturing operations to our internal manufacturing facilities. An alternative contract manufacturer may not be available to us when needed or may not be in a position to satisfy our quality or production requirements on commercially reasonable terms, including price. Any significant interruption in manufacturing our products would require us to reduce our supply products to our customers, which in turn would reduce our revenue, harm our relationships with the customers of these products and cause us to forego potential revenue opportunities.

Our revenues and costs may fluctuate over time, making it difficult to predict our future results of operations.

Our revenue, gross margin and results of operations have varied significantly and are likely to continue to vary from quarter to quarter due to a number of factors, many of which are not within our control. For instance, changes in gross margin may result from various factors, such as changes in pricing, changes in our fixed costs, changes in the cost of labor, changes in the mix of our products sold, changes in the amount of product manufactured versus the amount of product sold over time, and charges for excess and obsolete inventory. In addition, during 2012, we established a Russian subsidiary. However we have limited history operating in the Russian Federation, which makes it difficult to evaluate our business and financial prospects there. It is difficult for us to accurately forecast our future revenue and gross margin and plan expenses accordingly and, therefore, it is difficult for us to predict our future results of operations.

We must continually achieve new design wins and enhance existing products or our business and future revenue may be harmed.

The markets for our products are characterized by frequent new product introductions, changes in customer requirements and evolving industry standards, all with an underlying pressure to reduce cost and meet stringent reliability and qualification requirements. Our future performance will depend on our successful development, introduction and market acceptance of new and enhanced products that address these challenges. The anticipated or actual introduction of new and enhanced products by us and by our competitors may cause our customers to defer or cancel orders for our existing products. In addition, the introduction of new products by us or our competitors could result, and in the past, has resulted, in a slowdown in demand for our existing products and could result, and in the past, has resulted, in a write-down in the value of inventory. We have both recently and in the past experienced a slowdown in demand for existing products and delays in new product development, and such delays may occur in the future. To the extent customers defer or cancel orders for our products for any reason or we fail to achieve new design wins, our competitive position would be adversely affected and our ability to grow revenue would be impaired.

Product development delays may result from numerous factors, including:

•

changing product specifications and customer requirements;

•

unanticipated engineering complexities;

•

difficulties in reallocating engineering resources and overcoming resource limitations; and

•

changing market or competitive product requirements.

Furthermore, fast time-to-market with new products can be critical to success in our markets. It is difficult to displace an existing supplier for a particular type of product once a network equipment vendor has chosen a supplier, even if a later-to-market product provides superior performance or cost efficiency. If we are unable to make our new or enhanced products commercially available on a timely basis, we may lose existing and potential customers and our financial results would suffer.

The development of new, technologically-advanced products is a complex and uncertain process requiring frequent innovation, highly-skilled engineering and development personnel and significant capital, as well as the accurate anticipation of technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. Further, we cannot assure you that our new products will gain market acceptance or that we will be able to respond effectively to product introductions by competitors, technological changes or emerging industry standards. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, license these technologies from third parties, or remain competitive in our markets.

Our success will depend on our ability to anticipate and quickly respond to evolving technologies and customer requirements.

The communications networks industry is characterized by substantial investment in new technology and the development of diverse and changing technologies and industry standards. For example, new technologies are required to satisfy the emerging standards for 100Gbps, 400 Gbps and higher data transmission in communications networks.

Our ability to anticipate and respond to evolving technology, industry standards, customer requirements and product offerings, and to develop and introduce new and enhanced products and technologies, will be critical factors in our ability to succeed. If we are unable to anticipate and respond to such changes in the future, our competitive position could be adversely affected. In addition, the introduction of new products by other companies embodying new technologies, or the emergence of new industry standards, could render our existing products uncompetitive from a pricing standpoint, obsolete or otherwise unmarketable.

If our customers do not qualify our products for use, then our results of operations may suffer.

Prior to placing volume purchase orders with us, most of our customers require us to obtain their approval—called qualification in our industry—of our new and existing products, and our customers often audit our manufacturing facilities and perform other vendor evaluations during this process. The qualification process involves product sampling and reliability testing and collaboration with our product management and engineering teams in the design and manufacturing stages. If we are unable to qualify our products with customers, then our revenue would be lower than expected and we may not be able to recover the costs associated with the qualification process which would have an adverse effect on our results of operations.

In addition, due to evolving technological changes in our markets, a customer may cancel or modify a design project before we have qualified our product or begun volume manufacturing of a qualified product. It is unlikely that we would be able to recover the expenses for cancelled or unutilized custom design projects. It is difficult to predict with any certainty whether our customers will delay or terminate product qualification or the frequency with which customers will cancel or modify their projects, but any such delay, cancellation or modification would have a negative effect on our results of operations.

In particular, we have developed new technologies and products that we believe are key components in our customers’ systems for 100Gbps data transmission. There are multiple modulation approaches for these systems and not all are likely to be equally successful. While we are shipping certain products for 100Gbps system designs today, many of our products for these systems are currently being qualified for use by our customers. Our ability to successfully qualify and scale capacity for these new technologies and products is important to our ability to grow our business and market presence. If we are unable to qualify and sell any of these products in volume on time, or at all, our results of operations may be adversely affected.

We face intense competition which could negatively impact our results of operations and market share.

The communications networks industry is highly competitive. Our competitors range from large, international companies offering a wide range of products to smaller companies specializing in niche markets. In addition, we believe that a number of companies have developed or are developing planar lightwave, indium phosphide, or MEMS-based, PIC devices and other products that compete directly with our products. Current and potential competitors may have substantially greater financial, marketing, research and manufacturing resources than we possess, and there can be no assurance that our current and future competitors will not be more successful than us in specific product lines or as a whole.

Some of our competitors have substantially greater name recognition, technical, financial, and marketing resources, and greater manufacturing capacity, as well as better-established relationships with customers, than we do. Some of our competitors have more resources to develop or acquire, and more experience in developing or acquiring, new products and technologies and in creating market awareness for these products and technologies. Some of our competitors may be able to develop new products more quickly than us and may be able to develop products that are more reliable or which provide more functionality than ours. In addition, some of our competitors have the financial resources on business strategy to offer competitive products at below-market pricing levels that could prevent us from competing effectively and result in a loss of sales or market share or cause us to lower prices for our products.

We also face competition from some of our customers who evaluate our capabilities against the merits of manufacturing products internally. Due to the fact that such customers are not seeking to make a profit directly from the manufacture of these products, they may have the ability to manufacture competitive products at a lower cost than we would charge such customers. As a result, these customers may purchase less of our products and there would be additional pressure to lower our selling prices which, accordingly, would negatively impact our revenue and gross margin.

In particular we have developed new technologies and products that we believe are key components in our customers’ systems for 40Gbps and 100Gbps data transmission. The emergence of technologies and products from our competitors and their success in competing against our technologies and products for 40Gbps and 100Gbps data transmission could render our existing products uncompetitive from a pricing standpoint, obsolete or otherwise unmarketable.

Intense competition in our markets could result in aggressive business tactics by our competitors, including aggressively pricing their products or selling older inventory at a discount. If our current or future competitors utilize aggressive business tactics, including those described above, demand for our products could decline, we could experience delays or cancellations of customer orders, or we could be required to reduce our sales prices.

If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve our anticipated level of growth and our business could suffer.

Our success and ability to implement our business strategy depends upon the continued contributions of our senior management team and others, including our technical and operations employees. Our future success depends, in part, on our ability to attract and retain key personnel, including our senior management and others, and on the continued contributions of members of our senior management team and key technical and operations personnel, each of whom would be difficult to replace. The loss of services of members of our senior management team or key personnel or the inability to continue to attract and retain qualified personnel could have a material adverse effect on our business. Competition for highly skilled technical and operations people where we operate is extremely intense, and we continue to face challenges identifying, hiring and retaining qualified personnel in many areas of our business. If we fail to retain our senior management and other key personnel or if we fail to attract additional qualified personnel, our business could suffer.

The communications networks industry has long product development cycles requiring us to incur product development costs without assurances of an acceptable investment return.

The communications networks industry is highly capital-intensive. Large volumes of equipment and support structures are installed with considerable expenditures of funds and other resources, and long investment return period expectations. At the component supplier level, these cycles create considerable, typically multi-year, gaps between the commencement of new product development and volume purchases. Accordingly, we and our competitors often incur significant research and development and sales and marketing costs for products that, at the earliest, will be purchased by our customers long after much of the cost is incurred and, in some cases, may never be purchased due to changes in industry or customer requirements in the interim.

Due to changing industry and customer requirements, we are constantly developing new products, including seeking to further integrate functions on PICs and developing and using new technologies in our products. These development activities can and are expected to necessitate significant investment of capital. Our new products often require a long time to develop because of their complexity and rigorous testing and qualification requirements. Additionally, developing a manufacturing approach with an acceptable cost structure and yield for new products can be expensive and time-consuming. Due to the costs and length of research and development and manufacturing process cycles, we may not recognize revenue from new products until long after such expenditures are incurred, if at all, and our gross margin may decrease if our costs are higher than expected.

While we rely on many suppliers, there are a few which, if they stopped, decreased or delayed shipments to us, it could have an adverse effect on our business and financial results.

We depend on a limited number of suppliers for certain components and materials we have qualified to use in the manufacture of certain of our products. Some of these suppliers could disrupt our business if they stop, decrease or delay shipments or if the components they ship have quality, consistency, or business continuity issues. Some of these components and materials are available only from a sole source, or have been qualified only from a single source, although other sources may exist. For example, we use various types of adhesives that are sourced from various manufacturers, which presently are sole sources for these particular adhesives. Furthermore, there are a limited number of entities from which we could obtain certain other components and materials. We may also face component shortages if we experience increased demand for components beyond what our qualified suppliers can deliver. We have experienced component shortages from certain key suppliers, which has resulted and, if this occurs in the future, may result in an inability to meet customer demand, higher purchasing costs, or both. Although we engage in various actions to mitigate the impact of these shortages, any inability on our part to obtain sufficient quantities of critical components at reasonable costs could adversely affect our ability to meet demand for our products, which could cause our revenue, results of operations, or both to suffer.

Our customers generally restrict our ability to change the component parts in our modules without their approval. For more critical components, such as PICs, lasers and photo detectors, any changes may require repeating the entire qualification process. We typically have not entered into long-term or written agreements with our suppliers to guarantee the supply of the key components used in our products, and, therefore, our suppliers could stop supplying materials and equipment at any time or fail to supply adequate quantities of component parts on a timely basis. It is difficult, costly, time consuming and, on short notice, sometimes impossible for us to identify and qualify new component suppliers. The reliance on a sole supplier, single qualified vendor or limited number of suppliers could result in delivery and quality problems, reduced control over product pricing, reliability and performance and an inability to identify and qualify another supplier in a timely manner. We have in the past had to change suppliers, which has, in some instances, resulted in delays in product development and manufacturing and loss of revenue. Any such delays in the future may limit our ability to respond to changes in customer and market demands. Any supply deficiencies relating to the quality, quantities or timeliness of delivery of components that we use to manufacture our products could adversely affect our ability to fulfill our customer orders and our results of operations.

If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

Our success depends to a significant degree on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. We have applied for patent registrations in the U.S. and in other foreign countries, some of which have been issued. In addition, we have registered the trademark “NeoPhotonics” in the U.S. We cannot guarantee that our pending applications will be approved by the applicable governmental authorities. Moreover, our existing and future patents and trademarks may not be sufficiently broad to protect our proprietary rights or may be held invalid or unenforceable in court. A failure to obtain patents or trademark registrations or a successful challenge to our registrations in the U.S. or other foreign countries may limit our ability to protect the intellectual property rights that these applications and registrations intended to cover.

Policing unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken will prevent the misappropriation, unauthorized use or other infringement of our intellectual property rights. Further, we may not be able to effectively protect our intellectual property rights from misappropriation or other infringement in foreign countries where we have not applied for patent protections, and where effective patent, trademark, trade secret and other intellectual property laws may be unavailable, or may not protect our proprietary rights as fully as U.S. law. Particularly, our U.S. patents do not afford any intellectual property protection in China, Japan, Canada, Malaysia or the Philippines, where we have company operations, or in the Russian Federation, where we intend to expand operations. We seek to secure, to the extent possible, comparable intellectual property protections in China and other areas in which we operate. However, while we have issued patents and pending patent applications in China, portions of our intellectual property portfolio are not yet protected by patents in China. Moreover, the level of protection afforded by patent and other laws in countries such as China and Russia may not be comparable to that afforded in the U.S.

We attempt to protect our intellectual property, including our trade secrets and know-how, through the use of trade secret and other intellectual property laws, and contractual provisions. We enter into confidentiality and invention assignment agreements with our employees and independent consultants. We also use non-disclosure agreements with other third parties who may have access to our proprietary technologies and information. Such measures, however, provide only limited protection, and there can be no assurance that our confidentiality and non-disclosure agreements will not be breached, especially after our employees or those of our third-party contract manufacturers end their employment or engagement, and that our trade secrets will not otherwise become known by competitors or that we will have adequate remedies in the event of unauthorized use or disclosure of proprietary information. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products, otherwise obtain and use our intellectual property, or may independently develop similar or equivalent trade secrets or know-how. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed or misappropriated, our business, results of operations or financial condition could be materially harmed.

In the future, we may need to take legal actions to prevent third parties from infringing upon or misappropriating our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual property rights and determining their validity and scope could result in significant litigation costs and require significant time and attention from our technical and management personnel, which could significantly harm our business. In addition, we may not prevail in such proceedings. An adverse outcome of such proceedings may reduce our competitive advantage or otherwise harm our financial condition and our business.

We may be involved in intellectual property disputes in the future, which could divert management’s attention, cause us to incur significant costs and prevent us from selling or using the challenged technology.

Participants in the markets in which we sell our products have experienced frequent litigation regarding patent and other intellectual property rights. Numerous patents in these industries are held by others, including our competitors. In addition, from time to time, we have been notified that we may be infringing certain patents or other intellectual property rights of others. Regardless of their merit, responding to such claims can be time consuming, divert management’s attention and resources and may cause us to incur significant expenses. In addition, there can be no assurance that third parties will not assert infringement claims against us. While we believe that our products do not infringe in any material respect upon intellectual property rights of other parties and/or meritorious defense would exist with respect to any assertions to the contrary, we cannot be certain that our products would not be found infringing the intellectual property rights of others. Intellectual property claims against us could invalidate our proprietary rights and force us to do one or more of the following:

•

obtain from a third party claiming infringement a license to sell or use the relevant technology, which may not be available on reasonable terms, or at all;

•

stop manufacturing, selling, incorporating or using our products that use the challenged intellectual property;

•

pay substantial monetary damages; or

•

expend significant resources to redesign the products that use the technology and to develop non-infringing technology.

Any of these actions could result in a substantial reduction in our revenue and could result in losses over an extended period of time.

In May 3, 2012, we and Finisar agreed to further toll our respective claims until the refiling of certain of the previously asserted claims from this dispute. As a result, Finisar is permitted to bring a new lawsuit against us if it chooses to do so, and we may bring new claims against Finisar upon seven days written notice prior to filing such claims.

If we are unsuccessful in our defense of the Finisar patent infringement claims, a license to use the allegedly infringing technology may not be available to us at all, and if it is, it may not be available on commercially reasonable terms and therefore may limit or preclude us from competing in the market for optical transceivers in the U.S., which may have a material adverse effect on our results of operations and financial condition, and otherwise materially harm our business.

Although we believe that we would have meritorious defenses to the infringement allegations and intend to defend any new similar lawsuit vigorously, there can be no assurance that we will be successful in our defense. Even if we are successful, we may incur substantial legal fees and other costs in defending the lawsuit. Further, a new lawsuit, if brought by either party, would be likely to divert the efforts and attention of our management and technical personnel, which could harm our business.

If we fail to obtain the right to use the intellectual property rights of others which are necessary to operate our business, and to protect their intellectual property, our business and results of operations will be adversely affected.

From time to time we may choose to or be required to license technology or intellectual property from third parties in connection with the development of our products. We cannot assure you that third-party licenses will be available to us on commercially reasonable terms, if at all. Generally, a license, if granted, would include payments of up-front fees, ongoing royalties or both. These payments or other terms could have a significant adverse impact on our results of operations. The inability to obtain a necessary third-party license required for our product offerings or to develop new products and product enhancements could require us to substitute technology of lower quality or performance standards, or of greater cost, either of which could adversely affect our business. If we are not able to obtain licenses from third parties, if necessary, then we may also be subject to litigation to defend against infringement claims from these third parties. Our competitors may be able to obtain licenses or cross-license their technology on better terms than we can, which could put us at a competitive disadvantage. Also, we typically enter into confidentiality agreements with such third parties in which we agree to protect and maintain their proprietary and confidential information, including requiring our employees to enter into agreements protecting such information. There can be no assurance that the confidentiality agreements will not be breached by any of our employees or that such third parties will not make claims that their proprietary information has been disclosed.

Any potential dispute involving our patents or other intellectual property could also include our customers using our products, which could trigger our indemnification obligations to them and result in substantial expenses to us.

In any potential dispute involving our patents or other intellectual property, our customers could also become the target of litigation. Because we often indemnify our customers for intellectual property claims made against them for products incorporating our technology, any claims against our customers could trigger indemnification obligations in some of our supply agreements, which could result in substantial expenses such as increased legal expenses, damages for past infringement or royalties for future use. While we have not incurred any indemnification expenses to date, any future indemnity claim could adversely affect our relationships with our customers and result in substantial costs to us. Our insurance does not cover intellectual property infringement.

If we fail to adequately manage our long-term growth and expansion requirements, our business and financial results will suffer.

In recent years, we have experienced significant growth through, among other things, internal expansion programs, product development and acquisitions of other businesses and products. Our business has expanded to numerous locations, both foreign and domestic, and as a result become more complex, more demanding of management’s attention and subject to more subject to new laws and regulations. If we fail to comply with new laws and regulations related to the expansion of our business, our business could suffer.

We expect to continue to grow, which could require us to expand our manufacturing operations, including hiring new personnel, purchasing additional equipment, leasing or purchasing additional facilities, developing the management infrastructure and developing our suppliers to manage any such expansion. If we fail to secure these expansion requirements or manage our future growth effectively, our business could suffer.

We have pursued and may continue to pursue acquisitions. Acquisitions could be difficult to integrate, divert the attention of key personnel, disrupt our business, dilute stockholder value and impair our financial results.

As part of our business strategy, we have pursued and intend to continue to pursue acquisitions of complementary businesses, products, services or technologies that we believe could accelerate our ability to compete in our existing markets or allow us to enter new markets. Any of these transactions could be material to our financial condition and results of operations. For instance, in October 2011, we completed the acquisition of Santur, a designer and manufacturer of InP-based PIC products, and in March 2013 we completed the acquisition of the optical semiconductor business unit of LAPIS Semiconductor Co., Ltd. (OCU). If we fail to properly evaluate or integrate acquisitions, we may not achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate.

Acquisitions involve numerous risks, any of which could harm our business, including:

•

difficulties in integrating the operations, technologies, products, existing contracts, accounting and personnel of the target company and realizing the anticipated synergies of the combined businesses;

•

difficulties in realizing our expectations for the financial performance of the target company;

•

difficulties in supporting and transitioning customers, if any, of the target company;

•

Difficulties in managing and integrating different cultures with respect to our international acquisitions;

•

diversion of financial and management resources from existing operations;

•

the incurrence of debt to provide capital for any cash-based acquisitions;

•

the price we pay or other resources that we devote may exceed the value we realize, or the value we could have realized if we had allocated the purchase price or other resources to another opportunity;

•

risks of entering new markets in which we have limited or no experience;

•

potential loss of key employees, customers and strategic alliances from either our current business or the target company’s business;

•

assumption of unanticipated problems or latent liabilities, such as problems with the quality of the target company’s products;

•

exposure to environmental liabilities that have not yet been discovered associated with acquired businesses’ facilities;

•

expenses, distractions and actual or threatened claims or litigation resulting from acquisitions, whether or not they are completed;

•

inability to generate sufficient revenue to offset increased expenses association with any acquisition;

•

in the event of international acquisitions, risks associated with accounting and business practices that are different from applicable U.S. practices and requirements and

•

dilutive effect on our stock as a result of any equity-based acquisitions.

The failure to successfully evaluate and execute acquisitions or otherwise adequately address these risks could materially harm our business and financial results.

Acquisitions also frequently result in the recording of goodwill and other intangible assets which are subject to potential impairments which have occurred in the past and which, were they to occur in the future, could harm our financial results. As a result, if we fail to properly evaluate acquisitions or investments, we may not achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate. The failure to successfully evaluate and execute acquisitions or investments or otherwise adequately address these risks could materially harm our business and financial results.

Failure to realize the anticipated benefits from our acquisition of Santur and of OCU may affect our future results of operations and financial condition.

In connection with our acquisition of Santur and OCU, we have recently integrated Santur’s commercial operations and personnel into our existing infrastructure and intend to similarly integrate OCU’s business. If there are unexpected difficulties in our integration of these, the anticipated benefits of the transaction may not be realized or may take longer to realize than expected. The anticipated benefits of the acquisition could be materially reduced by a number of factors, including the following:

•

the future revenue and gross margins of the acquired products may be materially different from those we originally anticipated;

•

we could incur material unanticipated expenses;

•

the Santur or OCU products may not achieve the performance levels or specifications required by our customers;

•

we could have difficulty integrating and managing Santur’s and OCU’s international business locations in places where we did not previously have a significant or, in some cases, any business presence, including Malaysia, Canada and Japan;

•

claims or lawsuits may arise from the acquisition transaction or from Santur’s or OCU’s previous business operations;

•

we may experience difficulties in managing inventory and other operational processes in Santur’s and OCU’s former facilities that we acquire or lease as a result of the acquisitions;

•

we may experience difficulties in implementing effective internal controls over financial reporting as part of our integration of Santur and OCU, each of which was historically not subject as a stand-alone entity to the internal control requirements of a U.S. public company;

•

potential growth, expected financial results, perceived synergies and anticipated opportunities may not be realized through the ongoing integration of our Santur’s and OCU’s businesses;

•

we may face competition from existing customers as well as new competitors for legacy Santur or OCU products;

•

we could have difficulty implementing and maintaining financial reporting requirements for OCU’s previous business operations, which have not previously been previously audited nor subject to the internal compliance structure of a U.S. public company;

•

we could have difficulty implementing our existing management, production and accounting software and programs for OCU’s previous business operations;

•

we could incur additional costs associated with known and unknown environmental contamination of the real estate acquired from OCU; and

•

we could incur costs associated with new export or compliance issues associated with OCU products.

The occurrence of any or all of these events may have an adverse effect on our business and results of operations.

Natural disasters, terrorist attacks or other catastrophic events could harm our operations and our financial results.

Our worldwide operations could be subject to natural disasters and other business disruptions, which could harm our future revenue and financial condition and increase our costs and expenses. For example, our corporate headquarters and wafer fabrication facility in Silicon Valley, California and our Tokyo, Japan facility are located near major earthquake fault lines, and our manufacturing facilities are located in Shenzhen, China, an area that is susceptible to typhoons. Further, a terrorist attack, including one aimed at energy or communications infrastructure suppliers, could hinder or delay the development and sale of our products. In the event that an earthquake, tsunami, typhoon, terrorist attack or other natural or man-made catastrophe were to destroy any part of our facilities, destroy or disrupt vital infrastructure systems or interrupt our operations or the facilities or operations of our suppliers or customers for any extended period of time, our business, financial condition and results of operations would be materially and adversely affected. We are not insured against many natural disasters, including earthquakes.

Similarly, our worldwide operations could be subject to secondary effects of natural disasters and other business disruptions, which could harm our future revenue and financial condition and increase our costs and expenses. For instance, natural disasters and other business disruptions have created significant secondary effects in the past (such as the 2011 floods in Thailand and the 2011 earthquakes, tsunami and subsequent crisis relating to nuclear power facilities in Japan). Any of these types of events in the future could result in a slowdown of business or inability to manufacture products by our customers or others in the industry that are located in the affected areas; a disruption to the global supply chain for products manufactured in the affected areas that are included in the products either by us or by our customers; a disruption to manufacturing resulting from power shortages or other rationing of inputs to production; an increase in the cost of products that we purchase due to reduced supply; and other unforeseen impacts. These secondary effects could have a material and adverse effect on our business, financial condition, and results of operations.

Rapidly changing standards and regulations could make our products obsolete, which would cause our revenue and results of operations to suffer.

We design our products to conform to regulations established by governments and to standards set by industry standards bodies worldwide, such as The American National Standards Institute, the European Telecommunications Standards Institute, the International Telecommunications Union and the Institute of Electrical and Electronics Engineers, Inc. Various industry organizations are currently considering whether and to what extent to create standards for elements used in 100Gbps systems. Because certain of our products are designed to conform to current specific industry standards, if competing or new standards emerge that are preferred by our customers, we would have to make significant expenditures to develop new products. If our customers adopt new or competing industry standards with which our products are not compatible, or the industry groups adopt standards or governments issue regulations with which our products are not compatible, our existing products would become less desirable to our customers and our revenue and results of operations would suffer.

Failure to realize the anticipated benefits from our planned expansion in the Russian Federation may affect our future results of operations and financial condition.

In connection with our raising capital in an April 2012 private placement of common stock, we have established a wholly-owned subsidiary and company operations in the Russian Federation. The establishment of successful operations in the Russian Federation will require significant capital expenditure in a short amount of time, particularly in 2013 and 2014, and will be in part dependent on the cooperation of the Russian government and other third parties. If there are delays in our efforts to establish operations in the Russian Federation, the anticipated benefits of our Russian expansion may not be realized or may take longer to realize than expected. The anticipated benefits of our Russian expansion could be materially reduced by a number of factors, including the following:

•

the future revenue and gross margins of products produced in the Russian Federation may be materially different from those we originally anticipated;

•

we could incur material unanticipated expenses; and

•

we could have difficulty managing a business in the Russian Federation, where we did not previously have a material business presence.

In addition, in connection with the private placement transaction, we entered into a rights agreement with the sponsoring investor. Pursuant to the rights agreement, we have agreed to use at least $30 million of the proceeds from the private placement to establish a wholly-owned subsidiary and facility in the Russian Federation for the production of certain of our products. Pursuant to the rights agreement, failure to perform certain performance covenants set forth therein by July 31, 2014 (subject to extension to March 31, 2015, as set forth therein), will result in an obligation to pay damages to the investor in the amount of $5.0 million.

In recent years the Russian Federation has undergone substantial political, economic and social change. The business, legal and regulatory infrastructure in the Russian Federation is less well-developed that would generally exist in a more mature free market economy. In addition, the tax, currency and customs legislation within the Russian Federation is subject to varying interpretations and changes, which can occur frequently. The future economic direction of the Russian Federation remains largely dependent upon the effectiveness of economic, financial and monetary measures undertaken by the government, together with tax, legal, regulatory and political developments. Our failure to manage the risks associated with our planned Russian expansion could have a material adverse effect upon our results of operations.

The occurrence of any or all of these events may have an adverse effect on our business, and results of operations and financial condition.

Potential changes in our effective tax rate could negatively affect our future results.

We are subject to income taxes in the U.S., China and other various foreign jurisdictions, and our domestic and international tax liabilities are subject to the allocation of expenses in differing jurisdictions. Our tax rate is affected by changes in the mix of earnings and losses in countries with differing statutory tax rates, certain non-deductible expenses and the valuation of deferred tax assets and liabilities, including our ability to utilize our net operating losses. Increases in our effective tax rate could negatively affect our results of operations.

Our future results of operations may be subject to volatility as a result of exposure to fluctuations in foreign exchange rates, primarily the Chinese Renminbi (RMB)/U.S. dollar exchange rate.

We are exposed to foreign exchange risks. Foreign currency fluctuations may adversely affect our revenue and our costs and expenses, and hence our results of operations. A substantial portion of our business is conducted through our subsidiaries based in China, whose functional currency is the RMB. The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions. Since July 21, 2005, the RMB has no longer been pegged solely to the value of the U.S. dollar. Instead, the RMB is now pegged against a basket of currencies, determined by the People’s Bank of China, against which it can rise or fall by as much as 1.0% each day (which may further widen in the future). This change in policy has resulted in approximately 31% appreciation of the RMB against the U.S. dollar between July 21, 2005 and December 31, 2012. While the international reaction to the RMB revaluation has generally been positive, there remains significant international pressure on the Chinese government to adopt an even more flexible currency policy, which may result in a further and more significant appreciation of the RMB against the U.S. dollar. In the long term, the RMB may appreciate or depreciate significantly in value against the U.S. dollar, depending upon the fluctuation of the basket of currencies against which it is currently valued, or it may be permitted to enter into a full float, which may also result in a significant appreciation or depreciation of the RMB against the U.S. dollar.

Foreign currency exchange rates are subject to fluctuation and may cause us to recognize transaction gains and losses in our statements of operations. To the extent that transactions by our subsidiaries in China are denominated in currencies other than the RMB, we bear the risk that fluctuations in the exchange rates of the RMB in relation to other currencies could decrease our revenue or increase our costs and expenses, therefore having an adverse effect on our future results of operations.

While we generate a significant portion of our revenue in RMB, conversely, a majority of our operating expenses are in U.S. dollars. Therefore, any depreciation in the RMB against the U.S. dollar would adversely impact our revenue upon translation to U.S. dollars, but the positive impact on operating expenses would be less. This would result in an overall adverse effect on our results of operations and financial position. For example, for the year ended December 31, 2012, a 10% depreciation in RMB against the U.S. dollar would have resulted in an $9.9 million decrease in our revenue and a $0.7 million increase in our net loss for the period. Comparatively, for the year ended December 31, 2011, a 10% depreciation in RMB against the U.S. dollar would have resulted in a $11.2 million decrease in our revenue and a $0.7 million decrease in our net loss for the period.

In 2013, we transact in currencies that have had historical volatility, including Japanese Yen and Russian Rubles. Following our acquisition of OCU in 2013, the number and volume of our transactions in Japanese Yen has grown significantly, thus increasing our exposure to potential volatility in this currency. Fluctuations in the exchange rates of these currencies may cause us to recognize additional transaction gains or losses which could impact our results of operations. In the first three months of 2013, for example, the Japanese Yen weakened against the U.S. dollar.

To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedging transactions may be limited and we may not be able to successfully hedge our exposure. In addition, our currency exchange variations may be magnified by Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.

We face a variety of risks associated with international sales and operations, which if not adequately managed could adversely affect our business and financial results.

We currently derive, and expect to continue to derive, a significant portion of our revenue from international sales in various markets. In addition, a major portion of our operations is based in Shenzhen, China as well as our having additional operations in Japan, Canada and a contract manufacturing relationship in Malaysia. We also plan to establish a subsidiary and operations in the Russian Federation. Our international revenue and operations are subject to a number of material risks, including, but not limited to:

•

difficulties in staffing, managing and supporting operations in more than one country;

•

difficulties in enforcing agreements and collecting receivables through foreign legal systems;

•

fewer legal protections for intellectual property in foreign jurisdictions;

•

foreign and U.S. taxation issues and international trade barriers;

•

general economic and political conditions in the markets in which we operate;

•

difficulties in obtaining any necessary governmental authorizations for the export of our products to certain foreign jurisdictions;

•

fluctuations in foreign economies;

•

fluctuations in the value of foreign currencies and interest rates;

•

trade and travel restrictions;

•

outbreaks of avian flu, Severe Acute Respiratory Syndrome, or SARS, H1N1 swine flu or other contagious disease;

•

domestic and international economic or political changes, hostilities and other disruptions in regions where we currently operate or may operate in the future;

•

difficulties and increased expenses in complying with a variety of U.S. and foreign laws, regulations and trade standards, including the Foreign Corrupt Practices Act; and

•

different and changing legal and regulatory requirements in the jurisdictions in which we currently operate or may operate in the future.

Negative developments in any of these areas in China or other countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, difficulties in producing and delivering our products, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business. In addition, although we maintain an anti-corruption compliance program throughout our company, violations of our compliance program may result in criminal or civil sanctions, including material monetary fines, penalties and other costs against us or our employees, and may have a material adverse effect on our business.

In making an investment decision relating to our common stock, you should evaluate our business in light of the risks, expenses and difficulties frequently encountered by companies operating on a global platform, particularly companies in the rapidly changing communications networks industry.

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.

We are subject to export and import control laws, trade regulations and other trade requirements that limit which products we sell and where and to whom we sell our products, especially laser-dependent products (including those we recently acquired in the Santur acquisition). In some cases, it is possible that export licenses would be required from U.S. government agencies for some of our products in accordance with various statutory authorities, including but not limited to the International Traffic in Arms Regulations, the Export Administration Act of 1979, the International Emergency Economic Powers Act of 1977, the Trading with the Enemy Act of 1917 and the Arms Export Control Act of 1976 and various country-specific trade sanctions legislation. In addition, various countries regulate the import of certain technologies and have enacted laws that could limit our ability to distribute our products. We may not be successful in obtaining the necessary export and import licenses. Failure to comply with these and similar laws on a timely basis, or at all, or any limitation on our ability to export or sell our products or to obtain any required licenses would adversely affect our business, financial condition and results of operations.

Changes in our products or changes in export and import laws and implementing regulations may create delays in the introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or import of our products to certain countries altogether. Any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. In such event, our business and results of operations could be adversely affected.

We have identified a material weakness in our internal control over financial reporting which could, if not remediated, result in material misstatements in our financial statements.

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. As disclosed in Item 9A of our Annual Report on Form 10-K for year ended December 31, 2012, our management identified a material weakness in our internal control over financial reporting related to the reconciliation of inventory count results to the Company’s accounting records as of December 31, 2012 primarily in our Fremont, California facility which was a former facility of Santur (a company we acquired in 2011). A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of this material weakness, our management concluded that our internal control over financial reporting was not effective as of December 31, 2012, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—An Integrated Framework. We have developed a remediation plan designed to address this material weakness. If our remedial measures are insufficient to address the material weakness, or if additional material weaknesses in our internal control are discovered or occur in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results. For more information see “Part I. Item 4. Controls and Procedures”.

If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

Preparing our consolidated financial statements involves a number of complex manual and automated processes, which are dependent upon individual data input or review and require significant management judgment. One or more of these elements may result in errors that may not be detected and could result in a material misstatement of our consolidated financial statements. Beginning with the year ended December 31, 2011, we are required to comply with the internal control requirements of the Sarbanes-Oxley Act of 2002. In addition, we may experience difficulties in implementing effective internal controls over financial reporting as part of our integration of Santur and OCU. Santur and OCU have historically been private companies and not subject as stand-alone entities to the internal control requirements of a U.S. public company. We could also experience unanticipated additional operating costs in implementing and managing effective internal controls over financing reporting at the former Santur and OCU facilities and operations, which could adversely affect our financial performance.

If a material misstatement occurs in the future, we may fail to meet our future reporting obligations, we may need to restate our financial results and the price of our common stock may decline. Our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in the implementation, our business and operating results may be harmed and we may fail to meet our financial reporting obligations. Any failure of our internal controls could also adversely affect the results of the periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that is now applicable to us under the rules of the Securities and Exchange Commission, or the SEC. Effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, investors could lose confidence in our reported financial information, and the trading price of our stock could drop significantly.

*Covenants in our credit facilities may limit our flexibility in responding to business opportunities and competitive developments and increase our vulnerability to adverse economic or industry conditions.

We have lending arrangements with several financial institutions, including a new revolving credit and term loan agreement with Comerica Bank and East-West Bank in the U.S. as of March 2013, and our subsidiaries in China have line of credit arrangements. Our U.S. new revolving credit and term loan agreement requires us to maintain certain financial covenants, including a liquidity ratio and a quarterly ratio of funded debt to adjust EBITDA, and restricts our ability to take certain actions such as incurring additional debt, paying dividends, or engaging in certain transactions like mergers and acquisitions, investments and asset sales. These restrictions may limit our flexibility in responding to business opportunities, competitive developments and adverse economic or industry conditions. In addition, our obligations under our U.S. new revolving credit and term loan agreement with Comerica Bank and East-West Bank are secured by substantially all of our assets other than intellectual property assets, which limits our ability to provide collateral for additional financing. A breach of any of these covenants, or a failure to pay interest or indebtedness when due under any of our credit facilities, could result in a variety of adverse consequences, including the acceleration of our indebtedness.

We may be unable to utilize our net operating loss carryforwards to reduce our income taxes, which could adversely affect our future financial results.

As of December 31, 2012, we had net operating loss, or NOL, carryforwards for U.S. federal and state tax purposes of $205.3 million and $144.9 million, respectively. As these net operating losses have not been utilized, a portion began to expire in 2012 and will continue to expire further in the current year. The utilization of the NOL and tax credit carryforwards are subject to a substantial limitation imposed by Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, and similar state provisions. We recorded deferred tax assets, net of valuation allowance, for the NOL carryforwards currently available after considering the existing Section 382 limitation. If we incur an additional limitation under Section 382, then the NOL carryforwards, as disclosed, could be reduced by the impact of any future limitation that would result in existing NOL carryforwards and tax credit carryforwards expiring unutilized.

We incur increased costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives.

We became a public reporting company in February 2011. As a public company, we incur legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and the New York Stock Exchange, imposes additional requirements on public companies, including specific corporate governance practices. For example, the listing requirements of the New York Stock Exchange require that we satisfy certain corporate governance requirements relating to independent directors, audit and compensation committees, distribution of annual and interim reports, stockholder meetings, stockholder approvals, solicitation of proxies, conflicts of interest, stockholder voting rights and codes of conduct. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly. For example, these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantial additional costs to maintain the same or similar coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

We are subject to government regulations that could adversely impact our business.

The Federal Communications Commission, or FCC, has jurisdiction over the entire U.S. telecommunications industry and, as a result, our products and our U.S. customers are subject to FCC rules and regulations. Current and future FCC regulations affecting communications services, our products or our customers’ businesses could negatively affect our business. In addition, international regulatory standards could impair our ability to develop products for international customers in the future. Delays caused by our compliance with regulatory requirements could result in postponements or cancellations of product orders. Further, we may not be successful in obtaining or maintaining any regulatory approvals that may, in the future, be required to operate our business. Any failure to obtain such approvals could harm our business and results of operations.

We may utilize conflict minerals in our production or rely on suppliers who utilize conflict minerals in their production, and the use of such conflict minerals may negatively impact our results of operations.

In August 2012, the U.S. Securities and Exchange Commission adopted its final rule to implement Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act regarding reporting obligations for the use of conflict minerals originating in the Democratic Republic of the Congo and adjoining countries, and beginning on January 1, 2013, we became subject to these reporting obligations. In connection with these requirements, we have been contacted by several customers and suppliers regarding the new conflict mineral rules and reporting obligations and are working with these customers and suppliers to implement any necessary or requested compliance programs. As a result of these new rules, our results in operations may suffer for a variety of reasons, including:

•

difficulty in obtaining supplies that are conflict-free;

•

shipping delays or the cancellation of orders for our products;

•

costs associated with the implementation of the conflict minerals reporting obligations; and

•

reputational damage in the event that we determine our products do incorporate conflict minerals or cannot be verified as not incorporating conflict minerals.

In some instances, we rely on third-party sales representatives to assist in selling our products, and the failure of these representatives to perform as expected could reduce our future revenue.

Although we primarily sell our products through direct sales to systems vendors, we also sell our products to some of our customers through third-party sales representatives. Many of our third-party sales representatives also market and sell competing products from our competitors. Our third-party sales representatives may terminate their relationships with us at any time, or with short notice. Our future performance will also depend, in part, on our ability to attract additional third-party sales representatives that will be able to market and support our products effectively, especially in markets in which we have not previously distributed our products. If our current third-party sales representatives fail to perform as expected, our revenue and results of operations could be harmed.

We are subject to environmental, health and safety laws and regulations, which could subject us to liabilities, increase our costs, or restrict our business or operations in the future.

Our manufacturing operations and our products are subject to a variety of federal, state, local and international environmental, health and safety laws and regulations in each of the jurisdictions in which we operate or sell our products. These laws and regulations govern, among other things, air emissions, wastewater discharges, the handling and disposal of hazardous substances and wastes, soil and groundwater contamination, employee health and safety, and the use of hazardous materials in, and the recycling of, our products. Our failure to comply with present and future environmental, health or safety requirements, or the identification of contamination, could cause us to incur substantial costs, including cleanup costs, monetary fines, civil or criminal penalties, or curtailment of operations. In addition, the enactment of more stringent laws and regulations, or other unanticipated events could restrict our ability to expand our facilities, require us to install costly pollution control equipment or incur other additional expenses, or require us to modify our manufacturing processes or the contents of our products, which could have a material adverse effect on our business, financial condition and results of operations.

Additionally, increasing efforts to control emissions of greenhouse gases, or GHG, may also impact us. Additional climate change or GHG control requirements are under consideration at the federal level in the U.S. and in China. Additional restrictions, limits, taxes, or other controls on GHG emissions could increase our operating costs and, while it is not possible to estimate the specific impact any final GHG regulations will have on our operations, there can be no assurance that these measures will not have significant additional impact on us.

*Our Japan operations are subject to local environmental laws and regulations, and our failure to fully comply with all applicable environmental laws and regulations could negatively affect our operations and our future results.

Following our acquisition of OCU, we now own and operate a semiconductor facility in Japan which is subject to local environmental laws and regulations, including the Japanese Environmental Quality Standards (“JEQS”) and the Water Pollution Control Law (“Water Law”), which includes provisions for periodic monitoring of groundwater quality. The JEQS provides guidelines for specified substances in groundwater, primarily including metals and volatile organic compounds, include some that are either used in our operations or have been used in our facilities in prior years. In addition, the Soil Contamination Countermeasures Law includes regulatory standards for many of the same substances regulated under the Water Law, some that are either used in our operations or have been used in our facilities in prior years. Should any of these regulated materials be detected in local water or soil, we could be subject to local law remedies, which could affect our ability to operate or could negatively affect our results of operations.

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our stockholders.

We believe that our existing cash and cash equivalents, and cash flows from our operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12 months. We operate in an industry, however, that makes our prospects difficult to evaluate. It is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs. If this occurs, we may need additional financing to execute on our current or future business strategies, including to:

•

invest in our research and development efforts, including by hiring additional technical and other personnel;

•

expand our operating or manufacturing infrastructure;

•

acquire complementary businesses, products, services or technologies; or

•

otherwise pursue our strategic plans and respond to competitive pressures.

If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders, including those acquiring shares in our initial public offering. We cannot assure you that additional financing will be available on terms favorable to us, or at all. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our products, or otherwise respond to competitive pressures could be significantly limited.

Risks related to our operations in China

Our business operations conducted in China are critical to our success. A total of $121.2 million, or 49%, of our revenue in 2012 was recognized from customers for whom we shipped products to a location in China. Additionally, a substantial portion of our property, plant and equipment, 59% as of December 31, 2012, is located in China. We expect to make further investments in China in the foreseeable future. Therefore, our business, financial condition, results of operations and prospects are to a significant degree subject to economic, political, legal, and social events and developments in China.

Adverse changes in economic and political policies in China, or Chinese laws or regulations could have a material adverse effect on business conditions and the overall economic growth of China, which could adversely affect our business.

The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. In November 2012 China’s Communist Party announced the selection of a new Politburo Standing Committee, which controls government operations in China, and this recent change in leadership may affect Chinese laws or regulations in a manner that would adversely affect our business as set forth in this risk factor. The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Despite reforms, the government continues to exercise significant control over China’s economic growth by way of the allocation of resources, control over foreign currency-denominated obligations and monetary policy and provision of preferential treatment to particular industries or companies. Moreover, the laws, regulations and legal requirements in China, including the laws that apply to foreign-invested enterprises are relatively new and are subject to frequent changes. The interpretation and enforcement of such laws is uncertain. Any adverse changes to these laws, regulations and legal requirements, including tax laws, or their interpretation or enforcement, or the creation of new laws or regulations relating to our business, could have a material adverse effect on our business.

Furthermore, while China’s economy has experienced rapid growth in the past 20 years, growth has been uneven across different regions, among various economic sectors and over time. China has also in the past and may in the future experience economic downturns due to, for example, government austerity measures, changes in government policies relating to capital spending, limitations placed on the ability of commercial banks to make loans, reduced levels of exports and international trade, inflation, lack of financial liquidity, restrictions on the flow of capital and foreign exchange, stock market volatility and global economic conditions. Any of these developments could contribute to a decline in business and consumer spending in addition to other adverse market conditions, which could adversely affect our business.

Our cost advantage from having our manufacturing and part of our research and development in China may diminish over time due to increasing labor costs, which could materially and adversely affect our operating results.

The labor market in China, particularly in the manufacturing-heavy Southeast region of China where our manufacturing facilities are located, has experienced higher costs due to increased wages. We were required to pay additional employee benefits taxes beginning in late 2010 and were subject to increases in the minimum wage for hourly workers in 2011 and 2012. We are also subject to an increase in the minimum wage in 2013, and expect that we will be subject to further increase in personnel costs on taxes in the future due to market conditions and/or government mandates. If labor costs in China continue to increase, our gross margins and profit margins and results of operations may be adversely affected. In addition, our competitive advantage against competitors with manufacturing in traditionally higher cost countries would be diminished.

The termination, expiration or unavailability of our preferential income tax treatment in China may have a material adverse effect on our operating results.

Prior to January 1, 2008, entities established in China were generally subject to a 30% state and 3% local enterprise income tax rate. In accordance with the China Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, effective through December 31, 2007, our subsidiaries in China enjoyed preferential income tax rates. Effective January 1, 2008, the China Enterprise Income Tax Law, or the EIT law, imposes a single uniform income tax rate of 25% on all Chinese enterprises, including foreign-invested enterprises, and eliminates or modifies most of the tax exemptions, reductions and preferential treatment available under the previous tax laws and regulations. As a result, our subsidiaries in China may be subject to the uniform income tax rate of 25% unless we are able to qualify for preferential status. Currently, we have qualified for a preferential 15% tax rate that is available for new and high technology enterprises. The preferential rate applied to 2012, 2011 and 2010. We realized benefits from this 10% reduction in tax rate of $0.9 million, $0.4 million and $1.7 million for 2012, 2011 and 2010, respectively. The preferential rate has been approved to remain at 15% for 2013 and 2014. In order to retain the preferential rate, we must meet certain operating conditions, satisfy certain product requirements, meet certain headcount requirements and maintain certain levels of research expenditures. The preferential tax rate that we enjoy could be modified or discontinued altogether at any time, which could materially and adversely affect our financial condition and results of operations.

Our subsidiaries in China may be subject to restrictions on dividend payments, on making other payments to us or any other affiliated company, and on borrowing or allocating tax losses among our subsidiaries.

Current Chinese regulations permit our subsidiaries in China to pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations, which are different than U.S. accounting standards and regulations. In addition, our subsidiaries in China are required to set aside at least 10% of their respective accumulated profits each year, if any, to fund their statutory common reserves until such reserves have reached at least 50% of their respective registered capital, as well as to allocate a discretional portion of their after-tax profits to their staff welfare and bonus fund. As of December 31, 2012, our Chinese subsidiaries’ common reserves had not reached this threshold and, accordingly, these entities are required to continue funding such reserves with accumulated net profits. The statutory common reserves are not distributable as cash dividends except in the event of liquidation. In addition, current Chinese regulations prohibit inter-company borrowings or allocation of tax losses among subsidiaries in China. Further, if our subsidiaries in China incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Accordingly, we may not be able to move our capital easily, which could harm our business.

Restrictions on currency exchange may limit our ability to receive and use our revenue and cash effectively.

Because a substantial portion of our revenue is denominated in RMB, any restrictions on currency exchange may limit our ability to use revenue generated in RMB to fund any business activities we may have outside China or to make dividend payments in U.S. dollars. Under relevant Chinese rules and regulations, the RMB is currently convertible under the “current account,” which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and loans, without the prior approval of the State Administration of Foreign Exchange, or SAFE. Currently, our subsidiaries in China may purchase foreign exchange for settlement of “current account transactions,” including the payment of dividends to us, without the approval of SAFE. Although Chinese government regulations now allow greater convertibility of the RMB for current account transactions, significant restrictions remain. For example, foreign exchange transactions under our primary Chinese subsidiary’s capital account, including principal payments in respect of foreign currency-denominated obligations, remain subject to significant foreign exchange controls and the approval of SAFE. These limitations could affect the ability of our subsidiaries in China to obtain foreign exchange for capital expenditures through debt or equity financing, including by means of loans or capital contributions from us. We cannot be certain that Chinese regulatory authorities will not impose more stringent restrictions on the convertibility of the RMB, especially with respect to foreign exchange transactions. If such restrictions are imposed, our ability to adjust our capital structure or engage in foreign exchange transactions may be limited.

In August 2008, SAFE promulgated the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of Payment and Settlement of Foreign Currency Capital of Foreign-invested Enterprises, or Circular 142, a notice regulating the conversion by foreign-invested enterprises or FIE of foreign currency into RMB by restricting how the converted RMB may be used. Circular 142 requires that RMB converted from the foreign currency-dominated capital of a FIE may only be used for purposes within the business scope approved by the applicable government authority and may not be used for equity investments within China unless specifically provided for otherwise. In addition, SAFE strengthened its oversight over the flow and use of RMB funds converted from the foreign currency-dominated capital of a FIE. The use of such RMB may not be changed without approval from SAFE. Violations of Circular 142 may result in severe penalties, including substantial fines set forth in the Foreign Exchange Administration Regulations. As a result of Circular 142, our subsidiaries in China may not be able to convert our capital contributions to them into RMB for equity investments or acquisitions in China.

Uncertainties with respect to China’s legal system could adversely affect the legal protection available to us.

Our operations in China are governed by Chinese laws and regulations. Our subsidiaries in China are generally subject to laws and regulations applicable to foreign investments in China and, in particular, laws applicable to wholly foreign-owned enterprises. China’s legal system is a civil law system based on written statutes. Unlike common law systems, it is a legal system where decided legal cases have limited value as precedents. Since 1979, Chinese legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully-integrated legal system, and recently-enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, because these laws and regulations are relatively new, the interpretation and enforcement of these laws and regulations involve uncertainties, including regional variations within China. For example, we may have to resort to administrative and court proceedings to enforce the legal protection under contracts or law. However, since Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory and contract terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we would receive compared to more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into with our distributors, business partners, customers and suppliers. In addition, protections of intellectual property rights and confidentiality in China may not be as effective as in the U.S. or other countries or regions with more developed legal systems. Furthermore, the legal system in China is based in part on government policies and internal rules (some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until sometime after the violation. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention. All the uncertainties described above could limit the legal protections available to us and could materially and adversely affect our business and operations.

Chinese regulations relating to offshore investment activities by Chinese residents and employee stock options granted by overseas-listed companies may increase our administrative burden, restrict our overseas and cross-border investment activity or otherwise adversely affect the implementation of our acquisition strategy. If our stockholders who are Chinese residents, or our Chinese employees who are granted or exercise stock options, fail to make any required registrations or filings under such regulations, we may be unable to distribute profits and may become subject to liability under Chinese laws.

Chinese foreign exchange regulations require Chinese residents and corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment activities. These regulations apply to our stockholders who are Chinese residents and may apply to any offshore acquisitions that we make in the future. Pursuant to these foreign exchange regulations, Chinese residents who make, or have previously made, direct or indirect investments in offshore companies, will be required to register those investments. In addition, any Chinese resident who is a direct or indirect stockholder of an offshore company is required to file or update the registration with the local branch of SAFE, with respect to that offshore company, any material change involving its round-trip investment, capital variation, such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt investment or creation of any security interest. If any Chinese stockholder fails to make the required SAFE registration or file or update the registration, subsidiaries in China of that offshore parent company may be prohibited from distributing their profits and the proceeds from any reduction in capital, share transfer or liquidation, to their offshore parent company, and the offshore parent company may also be prohibited from injecting additional capital into their subsidiaries in China. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under Chinese laws for evasion of applicable foreign exchange restrictions. We cannot provide any assurances that all of our stockholders who are Chinese residents have made or obtained, or will make or obtain, any applicable registrations or approvals required by these foreign exchange regulations. The failure or inability of our stockholders in China to comply with the required registration procedures may subject us to fines and legal sanctions, restrict our cross-border investment activities, or limit our Chinese subsidiaries’ ability to distribute dividends or obtain foreign-exchange-dominated loans. Moreover, because of the uncertainties in the interpretation and implementation of these foreign exchange regulations, we cannot predict how they will affect our business operations or future strategy. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our results of operations and financial condition. In addition, if we decide to acquire a domestic company in China, we cannot assure you that we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrations required by these foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed Company, or the Stock Option Rule. Under the Stock Option Rule, Chinese residents who are granted stock options by an overseas publicly-listed company are required, through a Chinese agent or Chinese subsidiary of such overseas publicly-listed company, to register with SAFE and complete certain other procedures. We and our Chinese employees who have been granted stock options are subject to the Stock Option Rule. We have completed the process of registering our stock option and appreciation plans with SAFE. On February 20, 2012, SAFE issued the Circular on Relevant Issues concerning Foreign Exchange Administration for Individuals in PRC Participating in Equity Incentive Plan of Overseas-Listed Companies, or Circular 7, which provides detailed procedures for conducting foreign exchange matters related to domestic individuals’ participation in the equity incentive plans of overseas listed companies and supersedes the Stock Option Rule in its entirety. If we or our optionees in China fail to comply with the applicable regulations, we or our optionees in China may be subject to fines and legal sanctions. Several of our employees in China have exercised their stock options prior to our becoming an overseas publicly-listed company. Since there is not yet a clear regulation on how and whether Chinese employees can exercise their stock options granted by overseas private companies, it is unclear whether such exercises were permitted by Chinese laws and it is uncertain how SAFE or other government authorities will interpret or administer such regulations. Therefore, we cannot predict how such exercises will affect our business or operations. For example, we may be subject to more stringent review and approval processes with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may affect our results of operations and financial condition.

We may be obligated to withhold and pay individual income tax in China on behalf of our employees who are subject to individual income tax in China arising from the exercise of stock options. If we fail to withhold or pay such individual income tax in accordance with applicable Chinese regulations, we may be subject to certain sanctions and other penalties and may become subject to liability under Chinese laws.

The State Administration of Taxation has issued several circulars concerning employee stock options. Under these circulars, our Chinese employees (which could include both employees in China and expatriate employees subject to individual income tax in China) who exercise stock options will be subject to individual income tax in China. Our subsidiaries in China have obligations to file documents related to employee stock options with relevant tax authorities and withhold and pay individual income taxes for those employees who exercise their stock options. However, since there was not yet a clear regulation on how and whether Chinese employees could exercise stock options granted by overseas private companies and how Chinese employers shall withhold and pay individual taxes, the relevant tax authority verbally advised us that due to the difficulty in determining the fair market value of our shares as a private company, we did not need to withhold and pay the individual income tax for the exercises until after we completed our initial public offering in February 2011. Thus, we have not withheld or paid the individual income tax for the option exercises through the date of our initial public offering. However, we cannot assure you that the Chinese tax authorities will not act otherwise and request us to pay the individual income tax immediately and impose sanctions on us.

If the Chinese government determines that we failed to obtain approvals of, or registrations with, the requisite Chinese regulatory authority with respect to our current and past import and export of technologies, we could be subject to sanctions, which could adversely affect our business.

China imposes controls on technology import and export. The term “technology import and export” is broadly defined to include, without limitation, the transfer or license of patents, software and know-how, and the provision of services in relation to technology. Depending on the nature of the relevant technology, the import and export of technology to or from China requires either approval by, or registration with, the relevant Chinese governmental authorities.

If we are found to be, or to have been, in violation of Chinese laws or regulations, the relevant regulatory authorities have broad discretion in dealing with such violation, including, but not limited to, issuing a warning, levying fines, restricting us from benefiting from these technologies inside or outside of China, confiscating our earnings generated from the import or export of such technology or even restricting our future export and import of any technology. If the Chinese government determines that our past import and export of technology were inconsistent with, or insufficient for, the proper operation of our business, we could be subject to similar sanctions. Any of these or similar sanctions could cause significant disruption to our business operations or render us unable to conduct a substantial portion of our business operations and may adversely affect our business and result of operations.

China regulation of loans and direct investment by offshore holding companies to China entities may delay or prevent us from using the proceeds we received from our initial public offering to make loans or additional capital contributions to our China subsidiaries.

From time to time, we may make loans or additional capital contributions to our China subsidiaries. Any loans to our China subsidiaries are subject to China regulations and approvals. For example, any loans to our China subsidiaries to finance their activities cannot exceed statutory limits, must be registered with SAFE, or its local counterpart, and must be approved by the relevant government authorities. Any capital contributions to our China subsidiaries must be approved by the Ministry of Commerce of China or its local counterpart. In addition, under Circular 142, our China subsidiaries, as FIEs, may not be able to convert our capital contributions to them into RMB for equity investments or acquisitions in China.

We cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all, with respect to our future loans or capital contributions to our China subsidiaries. If we fail to receive such registrations or approvals, our ability to capitalize our China subsidiaries may be negatively affected, which could materially and adversely affect our liquidity and ability to fund and expand our business.

Dividends paid to us by our Chinese subsidiaries may be subject to Chinese withholding tax.

The EIT Law and the implementation regulations provide that a 10% withholding tax may apply to dividends payable to investors that are “non-resident enterprises,” to the extent such dividends are derived from sources within China and in the absence of any tax treaty that may reduce such withholding tax rate. The comprehensive Double Taxation Arrangement between China and Hong Kong generally reduces the withholding tax on dividends paid from a Chinese company to a Hong Kong company to 5%. Dividends paid to us by our Chinese subsidiaries will be subject to Chinese withholding tax if, as expected, we are considered a “non-resident enterprise” under the EIT Law. If dividends from our Chinese subsidiaries are subject to Chinese withholding tax, our financial condition may be adversely impacted to the extent of such tax.

Our worldwide income may be subject to Chinese tax under the EIT Law.

The EIT Law provides that enterprises established outside of China whose “de facto management bodies” are located in China are considered “resident enterprises” and are generally subject to the uniform 25% enterprise income tax on their worldwide income. Under the implementation regulations for the EIT Law issued by the State Council, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and treasury, and acquisition and disposition of properties and other assets of an enterprise. If we are deemed to be a resident enterprise for Chinese tax purposes, we will be subject to Chinese tax on our worldwide income at the 25% uniform tax rate, which could have an impact on our effective tax rate and an adverse effect on our net income (loss), however, dividends paid to us by our Chinese subsidiaries may not be subject to withholding if we are deemed to be a resident enterprise.

Dividends payable by us to our investors and gains on the sale of our common stock by our foreign investors may be subject to tax under Chinese law.

Under the EIT Law and implementation regulations issued by the State Council, a 10% withholding tax is applicable to dividends payable to investors that are “non-resident enterprises.” Similarly, any gain realized on the transfer of common stock by such investors is also subject to a 10% withholding tax if such gain is regarded as income derived from sources within China. If we are determined to be a “resident enterprise,” dividends and other income we pay on our common stock, or the gain you may realize from the transfer of our common stock, would be treated as income derived from sources within China. If we are required under the EIT Law to withhold tax from dividends payable to investors that are “non-resident enterprises,” or if a gain realized on the transfer of our common stock is subject to withholding, the value of your investment in our common stock may be materially and adversely affected.

Our contractual arrangements with our subsidiaries in China may be subject to audit or challenge by the Chinese tax authorities, and a finding that our subsidiaries in China owe additional taxes could substantially reduce our net income and the value of our stockholders’ investment.

Under the applicable laws and regulations in China, arrangements and transactions among related parties may be subject to audit or challenge by the Chinese tax authorities. We would be subject to adverse tax consequences if the Chinese tax authorities were to determine that the contracts with or between our subsidiaries were not executed on an arm’s length basis, and as a result the Chinese tax authorities could require that our Chinese subsidiaries adjust their taxable income upward for Chinese tax purposes. Such an adjustment could adversely affect us by increasing our tax expenses.

Because a substantial portion of our business is located in China, we may have difficulty maintaining adequate management, legal and financial controls, which we are required to do in order to comply with Section 404 of the Sarbanes-Oxley Act and securities laws, and which could cause a material adverse impact on our consolidated financial statements, the trading price of our common stock and our business.

Chinese companies have historically not adopted a western style of management and financial reporting concepts and practices, which includes strong corporate governance, internal controls and computer, financial and other control systems. Most of our middle and top management staff in China are not educated and trained in the western system, and we may have difficulty hiring new employees in China with experience and expertise relating to accounting principles generally accepted in the U.S. and U.S. public-company reporting requirements. As a result of these factors, we may experience difficulty in maintaining management, legal and financial controls, collecting financial data and preparing financial statements, books of account and corporate records and instituting business practices that meet U.S. public-company reporting requirements. We may, in turn, experience difficulties in maintaining adequate internal controls as required under Section 404 of the Sarbanes-Oxley Act. This may result in material weaknesses in our internal controls which could impact the reliability of our consolidated financial statements and prevent us from complying with SEC rules and regulations and the requirements of the Sarbanes-Oxley Act. Any such material weaknesses or lack of compliance with SEC rules and regulations could result in restatements of our historical consolidated financial statements, cause investors to lose confidence in our reported financial information, have an adverse impact on the trading price of our common stock, adversely affect our ability to access the capital markets and our ability to recruit personnel, lead to the delisting of our securities from the stock exchange on which they are traded. This could lead to litigation claims, thereby diverting management’s attention and resources, and which may lead to the payment of damages to the extent such claims are not resolved in our favor, lead to regulatory proceedings, which may result in sanctions, monetary or otherwise, and have a material adverse effect on our reputation and business.

See also the risk factor “If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.”

The turnover of direct labor in manufacturing industries in China is high, which could adversely affect our production, shipments, and results of operations.

Employee turnover of direct labor in the manufacturing sector in China is high and retention of such personnel is a challenge to companies located in or with operations in China. Although direct labor cost does not represent a high proportion of our overall manufacturing costs, direct labor is required for the manufacture of our products. If our direct labor turnover rates are higher than we expect, or we otherwise fail to adequately manage our direct labor turnover rates, then our results of operations could be adversely affected.

Our subsidiaries in China are subject to Chinese labor laws and regulations. Recently enacted Chinese labor laws may increase our operating costs in China, which could adversely affect our financial results.

China Labor Contract Law, effective January 1, 2008, together with its implementing rules, effective September 18, 2008, provides more protection to Chinese employees. Previously, an employer had discretionary power in deciding the probation period, not to exceed nine months. Additionally, the employment contract could only be terminated for cause. Under the new rules, the probation period varies depending on contract terms and the employment contract can only be terminated during the probation period for cause upon three days’ notice. Additionally, an employer may not be able to terminate a contract during the probation period on the grounds of a material change of circumstances or a mass layoff. The new law also has specific provisions on conditions when an employer has to sign an employment contract with open-ended terms. If an employer fails to enter into an open-ended contract in certain circumstances, the employer must pay the employee twice their monthly wage beginning from the time the employer should have executed an open-ended contract. Additionally an employer must pay severance for nearly all terminations, including when an employer decides not to renew a fixed-term contract.

On January 1, 2008, the Regulations on Paid Annual Leaves of Staff and Workers also took effect, followed by its implementing measures effective September 18, 2008. These regulations provide that employees who have worked consecutively for one year or more are entitled to paid annual leave. An employer must guarantee that employees receive the same wage income during the annual leave period as that for the normal working period. Where an employer cannot arrange annual leave for an employee due to production needs, upon agreement with the employee, the employer must pay daily wages equal to 300% of the employee’s daily salary for each day of annual leave forfeited by such employee.

The Shenzhen municipal government, effective December 2010, issued a measure to require all government agencies, public institutions, and enterprises in Shenzhen to pay a monthly housing fund. The housing fund is designed to enhance the welfare and increase the funds available to Shenzhen employees when buying, building, renovating, or overhauling owner-occupied houses. Employee and employers are required to make equal contributions to the housing fund, which can range between 5% and 20% of the employees’ average salary of the most recent year and we commenced making these contributions in the fourth quarter of 2010.

From time to time, the Chinese government has implemented requirements to increase the minimum wage for employees in China. These requirements have resulted in the past, and may result in the future, in higher employee costs for our personnel in China. Minimum wage rates generally vary by city and province within China and have historically increased as much as 15% on an annual basis. We were required to increase wages to comply with these requirements and it may be necessary for us to increase wages more than the minimum wage adjustment requires due to market conditions or additional government mandates. If labor costs in China continue to increase, our gross margins, profit margins and results of operations may be adversely affected. In addition, our competitive advantage against competitors with personnel costs or manufacturing in traditionally higher cost countries may be diminished. These newly introduced laws and regulations may materially increase the costs of our operations in China.

Adoption of international labor standards may increase our direct labor costs.

International standards of corporate social responsibility include strict requirements on labor work practices and overtime. As global service providers and their network equipment vendors adopt these standards, we have in the past incurred and may be required in the future to incur additional direct labor costs associated with our compliance with these standards.

If any of our subsidiaries in China becomes the subject of a bankruptcy or liquidation procedures, we may lose the ability to use its assets.

Because a substantial portion of our business and revenue are derived from China, if any of our subsidiaries in China goes bankrupt and all or part of its assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all of our operations in China. Any delay, interruption or cessation of all or a part of our operations in China would negatively impact our ability to generate revenue and otherwise adversely affect our business.

We may be exposed to liabilities under the FCPA and Chinese anti-corruption laws, and any determination that we violated these laws could have a material adverse effect on our business.

We are subject to the Foreign Corrupt Practice Act of 1977, or FCPA, and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties by U.S. persons and issuers as defined by the statute, for the purpose of obtaining or retaining business. We have operations, agreements with third parties and we make the majority of our sales in China. China also strictly prohibits bribery of government officials. Our activities in China create the risk of unauthorized payments or offers of payments by our employees, consultants, sales agents or distributors, even though they may not always be subject to our control. It is our policy to implement safeguards to discourage these practices by our employees. However, our existing safeguards and any future improvements may prove to be less than effective, and our employees, consultants, sales agents or distributors may engage in conduct for which we might be held responsible. Violations of the FCPA or Chinese anti-corruption laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, operating results and financial condition. In addition, the U.S. government may seek to hold us liable for successor liability FCPA violations committed by companies in which we invest or that we acquire.

Risks related to ownership of our common stock

Our financial results may vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.

Our quarterly revenue and results of operations have varied in the past and may continue to vary significantly from quarter to quarter. This variability may lead to volatility in our stock price as research analysts and investors respond to these quarterly fluctuations. These fluctuations are due to numerous factors, including:

•

fluctuations in demand for our products;

•

the timing, size and product mix of sales of our products;

•

changes in our pricing and sales policies or the pricing and sales policies of our competitors;

•

our ability to design, manufacture and deliver products to our customers in a timely and cost-effective manner and that meet customer requirements;

•

quality control or yield problems in our manufacturing operations;

•

our ability to timely obtain adequate quantities of the components used in our products;

•

length and variability of the sales cycles of our products;

•

unanticipated increases in costs or expenses; and

•

fluctuations in foreign currency exchange rates.

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect our quarterly and annual results of operations in the future. In addition, a significant amount of our operating expenses is relatively fixed in nature due to our internal manufacturing, research and development, sales and general administrative efforts. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify the adverse impact of such revenue shortfall on our results of operations. Moreover, our results of operations may not meet our announced guidance or the expectations of research analysts or investors, in which case the price of our common stock could decrease significantly. There can be no assurance that we will be able to successfully address these risks.

Our stock price may be volatile.

The market price of our common stock could be subject to wide fluctuations in response to, among other things, the risk factors described in this section of our Quarterly Report on Form 10-Q, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us.

The stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions, such as recessions, sovereign debt or liquidity issues, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

In the past, many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may become the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

If research analysts do not publish research about our business or if they issue unfavorable commentary or downgrade our common stock, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that research analysts publish about us and our business. The price of our common stock could decline if one or more research analysts downgrade our stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business. If one or more of the research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price or trading volume to decline.

The concentration of our capital stock ownership with our principal stockholders, executive officers and directors and their affiliates will limit other stockholders’ ability to influence corporate matters.

As of April 30, 2013, our executive officers and directors, and entities that are affiliated with them, beneficially own an aggregate of approximately 54% of our outstanding common stock. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders. Also, as a result, these stockholders, acting together, may be able to control our management and affairs and matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. Consequently, this concentration of ownership may have the effect of delaying or preventing a change in control, including a merger, consolidation or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if such a change in control would benefit our other stockholders.

We currently do not intend to pay dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We currently do not plan to declare dividends on shares of our common stock in the foreseeable future. In addition, the terms of our U.S. revolving credit and term loan agreement with Comerica Bank and East-West Bank restrict our ability to pay dividends. Consequently, your only opportunity to achieve a return on your investment in our company will be if the market price of our common stock appreciates and you sell your shares at a profit. There is no guarantee that the price of our common stock that will prevail in the market after our initial public offering will ever exceed the price that you pay.

Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:

•

providing for a classified board of directors with staggered, three-year terms;

•

not providing for cumulative voting in the election of directors;

•

authorizing our board of directors to issue, without stockholder approval, preferred stock rights senior to those of common stock;

•

prohibiting stockholder action by written consent;

•

limiting the persons who may call special meetings of stockholders; and

•

requiring advance notification of stockholder nominations and proposals.

In addition, we have been governed by the provisions of Section 203 of the Delaware General Corporate Law since the completion of our initial public offering. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from engaging in certain business combinations without approval of substantially all of our stockholders for a certain period of time.

These and other provisions in our amended and restated certificate of incorporation, our amended and restated bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.
