Security valuation. Investments are stated at value as of the close of the regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. The Fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these techniques are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes significant unobservable inputs when market prices are not readily available or reliable, including the Fund’s own assumptions in determining the fair value of investments. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the values by input classification of the Fund’s investments as of April 30, 2010, by major category type:


			LEVEL 2	LEVEL 3

During the six-month period ended April 30, 2010, there were no significant transfers in/out of Level 1 and Level 2 assets.

In order to value the securities, the Fund uses the following valuation techniques. Equity securities held by the Fund are valued at the last sale price or official closing price on the principal securities exchange on which they trade. In the event there were no sales during the day or closing prices are not available, then securities are valued using the last quoted bid or evaluated price. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing service. Certain securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Certain short-term securities are valued at amortized cost.

Other portfolio securities and assets, where market quotations are not readily available, are valued at fair value, as determined in good faith by the Fund’s Pricing Committee, following procedures established by the Board of Trustees. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of trading on the NYSE. The values of non-U.S. securities, used in computing the net asset value of the Fund’s shares, are generally determined at these times. Significant market events that affect the values of non-U.S. securities may occur after the time when the valuation of the securities is generally determined and the close of the NYSE. During significant market events, these securities will be valued at fair value, as determined in good faith, following procedures established by the Board of Trustees.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation. Dividend income is recorded on the ex-date except for certain foreign dividends where the ex-date may have passed, which are recorded when the Fund becomes aware of the dividends. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful.

Overdrafts. Pursuant to the custodian agreement, the Fund’s custodian may, in its discretion, advance funds to the Fund to make properly authorized payments. When such payments result in an overdraft, the Fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian has a lien, security interest or security


Semiannual report \| Income Securities Trust	27

entitlement in any Fund property, that is not segregated, to the maximum extent permitted by law to the extent of any overdraft.

Expenses. The majority of expenses are directly attributable to an individual fund. Expenses that are not readily attributable to a specific fund are allocated among all funds in an equitable manner, taking into consideration, among other things, the nature and type of expense and the fund’s relative assets. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Stripped securities. Stripped mortgage backed securities are financial instruments that derive their value from other instruments so that one class receives the entire principal from the underlying mortgage assets (PO or principal only), while the other class receives the interest cash flows (IO or interest only). Both PO and IO investments represent an interest in the cash flows of an underlying stripped mortgage backed security. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully receive its initial investment in an IO security. The market value of these securities can be extremely volatile in response to changes in interest rates. In addition, these securities present additional credit risk such that the Fund may not receive all or part of its principal because the counterparty or issuer has defaulted on its obligation.

Federal income taxes. The Fund intends to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

For federal income tax purposes, the Fund has a capital loss carryforward of $17,399,381 available to offset future net realized capital gains. The following table details the capital loss carryforward available as of October 31, 2009.


CAPITAL LOSS CARRYFORWARD EXPIRING AT OCTOBER 31

2012	2013	2014	2015	2016	2017

$2,123,466	$2,443,482	$3,342,775	$1,351,797	$1,367,076	$6,770,785

As of October 31, 2009, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition or disclosure. The Fund’s federal tax return is subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The Fund generally declares and pays dividends quarterly and capital gain distributions, if any, annually.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Material distributions in excess of tax basis earnings and profits, if any, are reported in the Fund’s financial statements as a return of capital.

Capital accounts within financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period. Permanent book-tax differences are primarily attributable to derivative transactions, amortization and accretion on debt securities, defaulted bonds and paydowns.

Statement of cash flows. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows is the amount included in the Fund’s Statement of Assets and Liabilities and represents the cash on hand at its custodian and does not include any short-term investments.

Note 3 — Derivative instruments

The Fund may invest in derivatives, including future contracts and swap contracts, in order to meet its investment objectives. The Fund may use derivatives to manage against enhance gain/income, manage duration, gain exposure to certain securities markets and to manage against anticipated interest rate changes.

The use of derivatives may involve risks different from, or potentially greater than, the risks associated with investing directly in securities. Specifically, derivatives expose a Fund to the risk that the counterparty to an over-the-counter (OTC) derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction. If the counterparty defaults, the Fund will have contractual remedies, but there is no assurance that the counterparty will meet its contractual obligations or the Fund will succeed in enforcing them.

Futures. A future is a contractual agreement to buy or sell a particular commodity, currency, or financial instrument at a pre-determined price in the future. Risks related to the use of futures contracts include possible illiquidity of the future markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values and/or interest rates and potential losses in excess of the fund’s initial investment.

Futures contracts are valued at quoted daily settlement prices established by the exchange on which they trade. Upon entering into a futures contract, the Fund is required to deposit initial margin with the broker in the form of cash or securities. The amount of required margin is generally based on a percentage of the contract value; this amount is the initial margin for the trade. The margin deposit must then be maintained at the established level over the life of the contract. Futures contracts are marked to market daily and an appropriate payable or receivable for the change in value (variation margin) is recorded by the Fund.

During the six months ended April 30, 2010, the Fund used futures contracts to manage duration of the portfolio. The following table summarizes the contracts held at April 30, 2010. The range of futures contracts notional amounts held by the Fund during the six months ended April 30, 2010 was approximately $2.7 to $7.1 million.

U.S. Treasury 10-Year
Note Futures	23	Short	Jun-10	$2,672,966	(38,877)

					($29,552)

Swaps. The Fund may enter into interest rate, credit default, and other forms of swap agreements. Swap agreements are privately negotiated agreements between a Fund and counterparty to exchange cash flows, assets, foreign currencies or market-linked returns at specified intervals. Swaps are marked to market daily based upon values from third party vendors or broker quotations, and the change in value is recorded as an unrealized appreciation/depreciation of swap contracts.

Upfront payments made/received by the Fund are amortized/accreted for financial reporting purposes, with the unamortized/unaccreted portion included in the Statement of Assets and Liabilities. A termination payment by the counterparty or the Fund is recorded as realized gain or loss, as well as, the net periodic payments received or paid by a Fund.


Semiannual report \| Income Securities Trust	29

Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may amount to values that are in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for the swap, that a counterparty may default on its obligation or delay payment under the swap terms. The counterparty may disagree or contest the terms of the swap. Market risks may also accompany the swap, including interest rate risk. The Fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.

Interest rate swaps. Interest rate swaps represent an agreement between a Fund and counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The Fund settles accrued net interest receivable or payable under the swap contracts on a periodic basis.

During the six months ended April 30, 2010, the Fund used interest rate swaps in anticipation of rising interest rates. The following table summarizes the interest rate swap contracts held as of April 30, 2010. During the six months ended April 30, 2010, the Fund invested in interest rate swaps with total notional values as represented below.

Note 4 — Guarantees and indemnifications

Under the Fund’s organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred.

Note 5 — Fees and transactions with affiliates

John Hancock Advisers, LLC (the Adviser) serves as investment adviser for the Fund. The Adviser is indirect wholly owned subsidiary of Manulife Financial Corporation (MFC).

Management fee. The Fund has an investment management contract with the Adviser under which the Fund pays a daily management fee to the Adviser equivalent, on an annual basis, to the sum of (a) 0.650% of the first $150,000,000 of the Fund’s average daily net assets and the value attributable to the credit facility agreement (collectively, managed assets), (b) 0.375% of the next $50,000,000, (c) 0.350% of the next $100,000,000 and (d) 0.300% of the Fund’s average daily managed assets in excess of $300,000,000. The Adviser has a subadvisory agreement with MFC Global Investment Management (U.S.), LLC, an indirect owned subsidiary of MFC and an affiliate of the Adviser. The Fund is not responsible for payment of the subadvisory fees. The investment management fees incurred for the six months ended April 30, 2010 were equivalent to an annual effective rate of 0.55% of the Fund’s managed assets.

Accounting and legal services. Pursuant to the Service Agreement, the Fund reimburses the Adviser for all expenses associated with providing the administrative, financial, legal, accounting and recordkeeping services of the Fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports amongst other services. The accounting and legal services fees incurred for the six months ended April 30, 2010, amounted to an annual rate of 0.02% of the Fund’s average daily net assets.

Trustee expenses. The Trust compensates each Trustee who is not an employee of the Adviser or its affiliates. These Trustees may, for tax purposes, elect to defer receipt of this compensation under the John Hancock Group of Funds Deferred Compensation Plan (the Plan). Deferred amounts are invested in various John Hancock funds and remain in the funds until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting liability are included in the accompanying Statement of Assets and Liabilities.

Note 7 — Leverage

The Fund utilizes a Committed Facility Agreement (CFA) to increase its assets available for investment. When the Fund leverages its assets, the common shareholders bear all fees associated with the facility and have the potential to benefit or be disadvantaged from the use of leverage. The Adviser’s fee is also incurred from the use of leverage. Consequently, the Fund and the Adviser may have differing interests in determining whether to leverage the Fund’s assets. Leverage creates risks which may adversely affect the return for the holders of common shares, including:

• the likelihood of greater volatility of net asset value and market price of common shares

• fluctuations in the interest rate paid for the use of the CFA

• increased operating costs, which may reduce the Fund’s total return

• the potential for a decline in the value of an investment acquired through leverage, while the Fund’s obligations under such leverage remains fixed

• the Fund is more likely to have to sell securities in a volatile market in order to meet asset coverage or other debt compliance requirements

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Fund’s return will be greater than if leverage had not been used, conversely, return would be lower if the cost of the leverage exceeds the income or capital appreciation derived.

Note 8 — Committed facility agreement

Effective June 2, 2009, the Fund entered into a CFA with a subsidiary of BNP Paribas (BNP) that allowed it to borrow up to an initial limit of $58 million and to invest the borrowings in accordance with its investment practices. On December 17, 2009, the Fund entered into an amendment to the CFA, increasing the amount the Fund can borrow under the CFA from $58 million to $90 million. Under the terms of the amendment, the Fund paid an arrangement fee of 0.25% on the increased amount of the committed financing upon execution of the amendment.

Borrowings under the CFA are secured by the assets of the Fund as disclosed in the schedule of investments. Interest charged is at the rate of one month LIBOR (reset daily) plus 0.85%. The Fund also pays a commitment fee of 0.60% per annum on the unused portion of the facility. Commitment and restructuring fees for the six months ended April 30, 2010 amounted to$30,050 and $104,445, respectively, and are included in the interest expense in the Statement of Operations. As of April 30, 2010, the Fund had borrowings of $80,000,000 at an interest rate of 1.13%, which are reflected in the Committed facility agreement payable on the Statement of asset and liabilities. November 1, 2009 to April 30, 2010, the average borrowing under the CFA and the effective average interest rate were $71,906,077 and 1.09%.

If the Fund elects to renew the CFA, a renewal fee of 0.25% of the maximum commitment financing is due to BNP each 540th calendar day. In addition, the Fund may terminate the agreement with 60 days’ notice if the Board of Trustees has determined that the elimination of all indebtedness


32	Income Securities Trust \| Semiannual report

leveraging in the Fund’s investments is in the best interest of the Fund’s shareholders. In certain circumstances, the CFA may automatically terminate, or it may be reduced to a 30-day facility. In addition, upon the occurrence of certain defaults, the lender may terminate the agreement upon 270 days’ notice.

On October 30, 2009, the Fund entered into an agreement with BNP that allows BNP to borrow a portion of the pledged collateral (Lent Securities) in an amount not to exceed the lesser of: (i) outstanding borrowings owed by the Fund to BNP and (ii) thirty three and one third percent of the Fund’s total assets. The Fund can designate any security within the pledged collateral as ineligible to be a Lent Security and can recall any of the Lent Securities. The Fund also has the right to apply and set-off an amount equal to one hundred percent (100%) of the then-current fair market value of such Lent Securities against the current borrowings under the CFA.

Note 9 — Purchase and sale of securities

Purchases and sales of securities, other than short-term securities and U.S. Treasury obligations, aggregated $61,516,439 and $60,071,113, respectively for the six months ended April 30, 2010. Purchases and sales of U.S. Treasury obligations aggregated $63,021,153 and $44,833,965, respectively for the six months ended April 30, 2010.

Investment objective and policy

The Fund is a closed-end diversified management investment company, common shares of which were initially offered to the public on February 14, 1973, and are publicly traded on the NYSE. The Fund’s investment objective is to generate a high level of current income consistent with prudent investment risk. The Fund invests in a diversified portfolio of freely marketable debt securities and may invest an amount not exceeding 20% of its assets in income-producing preferred and common stock. Under normal circumstances, the Fund will invest at least 80% of net assets in income securities. Income securities will consist of the following: (i) marketable corporate debt securities, (ii) governmental obligations and (iii) cash and commercial paper. “Net assets” is defined as net assets plus borrowings for investment purposes. The Fund will notify shareholders at least 60 days prior to any change in this 80% investment policy.

It is contemplated that at least 75% of the value of the Fund’s total assets will be represented by debt securities, which have at the time of purchase a rating within the four highest grades as determined by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation. The Fund intends to engage in short-term trading and may invest in repurchase agreements.

Bylaws and Declaration of Trust

In November 2002, the Board of Trustees adopted several amendments to the Fund’s bylaws, including provisions relating to the calling of a special meeting and requiring advance notice of shareholder proposals or nominees for Trustee. The advance notice provisions in the bylaws require shareholders to notify the Fund in writing of any proposal which they intend to present at an annual meeting of shareholders, including any nominations for Trustee, between 90 and 120 days prior to the first anniversary of the mailing date of the notice from the prior year’s annual meeting of shareholders. The notification must be in the form prescribed by the bylaws. The advance notice provisions provide the Fund and its Trustees with the opportunity to thoughtfully consider and address the matters proposed before the Fund prepares and mails its proxy statement to shareholders. Other amendments set forth the procedures that must be followed in order for a shareholder to call a special meeting of shareholders. Please contact the Secretary of the Fund for additional information about the advance notice requirements or the other amendments to the bylaws.

On August 21, 2003, shareholders approved the amendment of the Fund’s bylaws effective August 26, 2003, to provide for the issuance of preferred shares.

On March 31, 2008, the shareholders approved an amendment to the Fund’s Declaration of Trust to permit the Fund’s Board of Trustees to delegate the authority to declare dividends to a Dividend Committee consisting of officers, employees or agents of the Fund.

Effective September 9, 2008, the Fund’s bylaws were amended with respect to notice requirements for Trustee nominations and other proposals by the Fund’s shareholders. These provisions require the disclosure of the nominating shareholder and the nominee’s investment interests as they relate to the Fund, as well as the name of any other shareholder supporting the nominee for election as a Trustee or the proposal of other business. In order for notice to be proper, such notice must disclose the economic interests of the nominating shareholder and nominee, including his or her holdings of shares in the Fund, the intent upon which those shares were acquired, and any hedging arrangements (including leveraged or short positions) made with respect to the shares of the Fund. Additionally, any material interest that the shareholder has in the business to be brought before the meeting must be disclosed.


34	Income Securities Trust \| Semiannual report

Financial futures contracts and options

The Fund may buy and sell financial futures contracts and options on futures contracts to hedge against the effects of fluctuations in interest rates and other market conditions. The Fund’s ability to hedge successfully will depend on the Adviser’s ability to predict accurately the future direction of interest rate changes and other market factors. There is no assurance that a liquid market for futures and options will always exist. In addition, the Fund could be prevented from opening, or realizing the benefits of closing out a futures or options position because of position limits or limits on daily price fluctuations imposed by an exchange.

The Fund will not engage in transactions in futures contracts and options on futures for speculation, but only for hedging or other permissible risk management purposes. All of the Fund’s futures contracts and options on futures will be traded on a U.S. commodity exchange or board of trade. The Fund will not engage in a transaction in futures or options on futures if, immediately thereafter, the sum of initial margin deposits on existing positions and premiums paid for options on futures would exceed 5% of the Fund’s total assets.

Dividends and distributions

During the six month period ended April 30, 2010, dividends from net investment income totaling $0.57 per share were paid to shareholders. The dates of payments and the amounts per share were as follows:


PAYMENT DATE	DIVIDEND

December 31, 2009	0.2914
March 31, 2010	0.2755
Total	$0.5669

Dividend reinvestment plan

The Fund offers its shareholders a Dividend Reinvestment Plan (the Plan), which offers the opportunity to earn compounded yields. Each shareholder will automatically have all distributions of dividends and capital gains reinvested by Mellon Bank, N.A. as Plan agent (the Plan Agent), unless an election is made to receive cash. Each registered shareholder will receive from the Plan Agent an authorization card to be signed and returned if the shareholder elects to receive distributions from net investment income in cash or elects not to receive capital gains distributions in the form of a shares dividend. Shareholders may also make their election by notifying the Plan Agent by telephone or by visiting the Plan Agent’s Web site at www.melloninvestor.com. Holders of common shares who elect not to participate in the Plan will receive all distributions in cash paid by check mailed directly to the shareholder of record (or if the common shares are held in street or other nominee name, then to the nominee) by the Plan Agent, as dividend disbursing agent. Shareholders whose shares are held in the name of a broker or nominee, or shareholders transferring such an account to a new broker or nominee, should contact the broker or nominee to determine whether and how they may participate in the Plan.

The Plan Agent serves as agent for the holders of common shares in administering the Plan. After the Fund declares a dividend or makes a capital gains distribution, the Plan Agent will, as agent for the participants, receive the cash payment and use it to buy common shares in the open market, on the New York Stock Exchange or elsewhere, for the participants’ accounts. The Fund will not issue any new shares in connection with the Plan. The Plan Agent’s fees for the handling of reinvestment of dividends and other distributions will be paid by the Fund. Each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open market purchases in connection with the reinvestment of distributions. There are no other charges to participants for reinvesting dividends or capital gain distributions.

Participants in the Plan may withdraw from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s Web site at www.melloninvestor.com. Such


Semiannual report \| Income Securities Trust	35

withdrawal will be effective immediately if received prior to a dividend record date; otherwise, it will be effective for all subsequent dividend record dates. When a participant withdraws from the Plan or upon termination of the Plan, as provided below, either a cash payment will be made to the participant for the full value of the common shares credited to the account upon instruction by the participant, or certificates for whole common shares credited to his or her account under the Plan will be issued and a cash payment will be made for any fraction of a common share credited to such account. The Plan Agent maintains each shareholder’s account in the Plan and furnishes monthly written confirmations of all transactions in the accounts, including information needed by the shareholders for personal and tax records. The Plan Agent will hold common shares in the account of each Plan participant in non-certificated form in the name of the participant. Proxy material relating to shareholders’ meetings of the Fund will include those shares purchased as well as shares held pursuant to the Plan. In the case of shareholders such as banks, brokers or nominees, which hold common shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of common shares certified from time to time by the record shareholders as representing the total amount registered in the record shareholder’s name and held for the account of beneficial owners who are participants in the Plan. Shares may be purchased through broker-dealers.

Dividends and capital gains distributions are taxable whether received in cash or reinvested in additional common shares, and the automatic reinvestment of dividends and capital gain distributions will not relieve participants of any U.S. federal income tax that may be payable or required to be withheld on such dividends or distributions. The amount of dividends to be reported on 1099-DIV should be the amount of cash used by the Plan Agent to purchase shares in the open market, including the amount of cash allocated to brokerage commissions paid on such purchases. Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan as applied to any distribution paid subsequent to written notice of the change sent to all shareholders of the Fund at least 90 days before the record date for the dividend or distribution. The Plan may be amended or terminated by the Plan Agent by at least 90 days’ written notice to all shareholders of the Fund. All correspondence or additional information concerning the Plan should be directed to the Plan Agent, Mellon Bank, N.A., c/o Mellon Investor Services, P.O. Box 358015, Pittsburgh, PA 15252-8015 (Telephone:1-800-852-0218).
