growth of electronic trading; changes in our rate per contract due to shifts in the mix of the products traded, the trading venue and the mix of
customers (whether the customer receives member or non-member fees or participates in one of our various incentive programs) and the
impact of our tiered pricing structure; the ability of our financial safeguards package to adequately protect us from the credit
risk of our
clearing firms; changes in price levels and volatility in the derivatives markets and in underlying fixed income, equity, foreign exchange and
commodities markets; economic, political and market conditions; our ability to accommodate increases in trading volume without failure or
degradation of performance of our systems; our ability to execute our growth strategy and maintain our growth effectively; our ability to

New product volume from derivatives exchanges


23
Copyright Chicago Mercantile Exchange Inc. All rights reserved.
Potential for Competitive Entry and Expansion Constrains Pricing
The threat of groups of large customers shifting trading volumes
to
alternate exchanges disciplines exchange pricing.
Select large customers account for a sizeable share of trading for major CME and CBOT
contracts and can create new exchanges for high volume contracts.
The Commodity Futures Modernization Act of 2000 simplified the regulatory approval
process.
Exchanges have entered and competed to attract liquidity.
Intercontinental Exchange (ICE) was formed by a collection of major dealers in 2000 and
acquired the IPE exchange in 2001.  It is now the second largest
energy futures exchange.
NYSE has stated its intention to expand into futures exchange business.
Exchange and clearing facilities are readily available
Electronic platforms are available from third parties, including LIFFE’s CONNECT platform
and OM’s Click platform.
Clearing services can be organized by a consortium of customers and are available from
such third parties as Eurex Clearing AG, LCH, New York Clearing Corp., OM, Options
Clearing Corp., NYMEX, and The Clearing Corporation.
Both clearing and electronic trading platforms are highly scalable and can be expanded
rapidly.
CME
effectively
doubled
the
size
of
its
clearing
operation
after
taking
on
CBOT’s
clearing
function.
Trading on additional commodities can be readily added to existing trading platforms.

Notes from past comments on fungibility
to the CFTC


26
Copyright Chicago Mercantile Exchange Inc. All rights reserved.
CFTC Roundtable
In 2002 CME participated in a CFTC Roundtable
discussion of fungibility
Through a written statement submitted in August 2002
Through a presentation to the CFTC later that fall
CME’s comments focused on 3 pillars
distinguishing futures exchanges that proscribed
fungibility would undermine
Innovation
Liquidity, open access and price transparency
Financial integrity


27
Copyright Chicago Mercantile Exchange Inc. All rights reserved.
3 Pillars -
Innovation
Diversity of futures contract designs
Securities exist independently and apart from securities exchanges
stock options were standardized by Put and Call Dealers Association
before 1972 introduction of CBOE
BUT …
futures are constructed products
that do not exist apart
from futures exchange –
invoking intellectual property issues
Futures exchanges attempt to add unique value –
products are
rarely generic, e.g.,
agencies, swaps
Innovation key to exchange value proposition and growth
Enforced or proscribed fungibility stifles new product innovation
At worst, it begs question –
why innovate? 


28
Copyright Chicago Mercantile Exchange Inc. All rights reserved.
3 Pillars -
Liquidity
Liquidity and price transparency
Futures only have utility if they offer enhanced liquidity
relative to cash or derivative market solutions
But …
“liquidity as elusive as it is vital”
Successful futures concentrate activity in open, transparent
marketplace, achieving “critical mass”
of liquidity
CME promotes openness and transparency
Price discovery, transparency, open market access and
competition enhanced by centralized liquidity pool


29

Control
Issue is actually about control of bid-offer spread
“The majority of [exchange] shareholders are locals whose
interest is in maintaining the grip of …
open outcry …
[preventing] …
other forms of trading –
such as internalization or
crossing
because of the rules requiring exposure to the floor
[or electronic order book].”
Kevin Davis in CFTC testimony  
Per former SEC Chairman Arthur Levitt …
“Internalization …
substantially reduce[s] the opportunity for
investor orders to interact …
[which] …
may hamper price
competition, interfere with …
public price discovery, and detract
from the depth and stability of the markets”
“Price matching dealers …
take advantage of the public price
discovery process …
but need not contribute to the process of
price discovery”
This creates “disincentives for vigorous price competition, which
could lead to wider bid-asked spreads, less depth, and higher
transaction costs …
all orders could receive poorer executions”

Conclusion
Motivation behind fungibility and common clearing
The proponents of fungibility and common clearing seek “to
internalize their dealings, take the markets upstairs and exploit the
profit from the bid/ask spreads.”
“In doing so, they will no doubt make lots of money, but there will
be two fundamental casualties in their wake.”
Casualties of fungibility
“The first [casualty] will be in the transparency implicit in the
exchange-transaction-process …
Need we revisit the causes of the
Enron debacle?”
“The second casualty will be that of innovation.  Does anyone here
remember the last innovation produced by a utility?”
