2006 Annual Report
Chicago Board Options Exchange

2006 was an historic year for CBOE on many  
levels. The record-setting numbers tell a great 
story — the leading U.S. options exchange in 
volume, a third consecutive year of record volume, 
increased market share and seat prices — but 
numbers don’t tell the whole story at CBOE. 

Accept No Substitute.

CBOE will embark on a new branding campaign in 
2007 in which the Exchange will be communicating to 
the world that CBOE is a vital necessity in the options 
marketplace for which there is no substitute. Additional 
details may be found on page 18 of this Annual Report. 

Accept No Substitute.

Letter from the Office of the Chairman

Several long-term initiatives were set in place during 2006 that not only drove our numbers to all-time highs,  
but also set the stage for CBOE’s future growth. Perhaps most significant was the Exchange’s conversion to a  
for-profit business model. There are many reasons behind CBOE’s decision to engage in this transformation, 
but ultimately, changing our business model will enable the Exchange to position itself most-effectively in a 
rapidly changing business environment. Streamlining the Exchange’s operations, creating new subsidiaries, 
such as the CBOE Stock Exchange (CBSX) and Market Data Express, and forming new alliances, exemplified 
by our collaboration with HedgeStreet, illustrate how CBOE has shifted the focus of its business to increasing 
and maximizing profitability. 

With the launch of CBSX, CBOE now offers options, futures and stocks — all on a single electronic trading 
platform. As the regulatory and competitive landscape continues to shift, the Exchange is extremely well 
positioned for the future as one of a select few exchanges to offer a multi-asset trading platform. Going  
forward, we expect that the Exchange’s members and customers will be able to realize economies of scale  
as they manage their cross-asset trading through a single, unified platform at CBOE. 

Our Hybrid Trading System continues to demonstrate that it is the most unique market model in the industry.  
In a fiercely competitive environment, the twin functionality of Hybrid — allowing for electronic and open 
outcry trading — is one of the many ways CBOE differentiates itself from its rivals. The expansion of the 
Remote Market Maker program furthered the benefits of Hybrid trading by increasing the number of market 
participants and deepening the liquidity at CBOE. 

Looking ahead, we expect that the two landmark regulatory initiatives taking effect in 2007 will have a  
positive impact on CBOE and the financial industry for years to come. The changes to the National Market  
System embodied in Reg NMS have ushered in a new era of competition in the securities industry, creating 
opportunities for new market centers such as the CBOE Stock Exchange. CBOE has long worked as a tireless 
advocate for expanding portfolio margining and the implementation of the new portfolio margining rules is 
expected to be one of the most significant developments to the securities industry in decades. True risk-based 
margining will likely free up tremendous amounts of capital, allowing investors to more appropriately allocate 
assets in their accounts. 

As the world’s premier options marketplace, CBOE remains committed to growing and advancing our industry. 
We embrace our role as industry leader and pledge to continue as the stewards for product innovation, 
investor education and industry advocacy. CBOE is, and will remain, the marketplace for options.

Record Setting Volume and Increasing Market Share

Busiest Year in CBOE History
2006 was a landmark year for CBOE as trading 
activity soared to new heights and dozens of volume 
records were established in exchange-wide volume, 
equity options volume, and index/exchange traded 
fund (ETF) options volume. The busiest day in CBOE 
history occurred on Friday, May 19, 2006 when 
5,816,336 contracts traded, while May 2006 was 
the busiest month in CBOE history as 70,522,508 
contracts traded.* 

In 2006, the busiest twelve months in CBOE’s 33-
year history, volume tallied 674.7 million contracts, 
the third consecutive year of record total annual 
volume. 2006 totals surpassed 2005’s volume of 
468.2 million contracts, the previous high mark, 
by 44%. Average daily volume during 2006 was 
2,688,189 contracts. At year’s end, Exchange open 
interest stood at 226.4 million contracts, 25% above 
the end of 2005. 

Volume on CBOE’s 1,900+ equity options rose 42% 
to 390.7 million contracts in 2006, easily topping 
the 275.6 million contracts traded in 2005, setting a 
new all-time record for total equity options volume in 
a year. The previous record for equity options annual 
volume of 278.9 million contracts was set in 2000. 
The five most actively-traded equity options at  
CBOE in 2006 were: Apple Computer, Inc. (AAPL), 
Google, Inc. (GOOG), Altria Group, Inc. (MO), 
General Motors Corporation (GM), and Microsoft 
Corporation (MSFT). 

2006 marked the sixth consecutive year of volume 
gains in index/ETF options. During 2006, a record 

284.0 million contracts traded, an increase of 48% 
above 2005’s volume of 192.5 million contracts. At  
the end of 2006, CBOE listed options on 28 broad- 
and sector-based indexes and 96 ETFs, as well as 
options on 4 interest rate products. 

Notably, six of CBOE’s index and ETF options 
products set individual annual trading records in 
2006: S&P 500 Index (SPX), up 45% over 2005 
to 104.3 million contracts; S&P 100 Index with 
European style exercise (XEO), up 93% to 3.7 
million; Standard & Poor’s Depositary Receipts/
SPDRs (SPY), up 49% to 24.1 million; Russell 2000 
Index (RUT), up 98% to 2.2 million; iShares Russell 
2000 Index Fund (IWM), up 177% to 44.9 million; 
and Nasdaq-100 Index (NDX), up 22% to 7.8 million.

Rising Market Share 
CBOE was the leading U.S. options exchange in 
2006, handling over one-third of all industry volume. 
CBOE’s market share of 33% was up 2.2 percentage 
points from 2005, widening the margin between the 
Exchange and its nearest competitor. In fact, CBOE 
was one of only two options exchanges to experience  
a market share gain of more than two percentage  
points for the year. Equity options market share rose  
2 percentage points during 2006 to 26%, ETF 
options market share rose 2.3 percentage points 
to 36%, while market share in cash index options 
remained unchanged at 85%.

 *These records have already been broken in 2007. On February 

27, 2007, 6,722,060 contracts traded, a new high for single day 
volume, while in March 2007, 82,963,812 contracts traded, 
making it the busiest month in CBOE history.

over 2005. New all-time records for IWM in

set during 2006.

Pursuing a New Business Model 

Conversion to a For-Profit Business Model
January 2006 began CBOE’s first year of operation 
as a for-profit organization. To set the stage for this 
transition, significant cost-reduction steps were 
taken, including an 11 percent reduction in staff 
and a comprehensive organizational overhaul that 
resulted in the implementation of cost reductions  
and greater operational efficiencies throughout  
the Exchange. 

Demutualization Begins
In September 2006, the CBOE Board of Directors 
announced their intention to initiate the process of 
demutualizing the Exchange, meaning CBOE will 
change its organizational structure from a non-
stock corporation owned by its members into a new 
holding company organized as a stock corporation 
owned by its stockholders. 

CBOE’s new structure will provide the Exchange 
with greater flexibility to respond to the demands 
of a rapidly changing regulatory and business 
environment. In addition, the Exchange will be 
able to pursue opportunities to engage in business 
combinations and joint ventures with other 
organizations, and to access capital markets in 
ways that were not available to CBOE as a non-stock 
membership corporation. 

S-4 Registration Statement Filed with SEC
In February 2007, the Exchange filed an S-4 
Registration Statement with the Securities and 
Exchange Commission (SEC) which details the 
terms of CBOE’s proposed demutualization. In the 
conversion, CBOE will become a wholly-owned 
subsidiary of a new holding company, CBOE 
Holdings, Inc. CBOE memberships existing at the 
time of the demutualization will be converted into 
shares of CBOE Holdings stock. CBOE’s proposed 
demutualization is subject to regulatory approval  
and a vote of the CBOE membership.

Seat Prices Reach New Highs
CBOE seat prices increased 100 percent, climbing 
from the first sale of $875,000 at the beginning of 
January 2006 to a record-breaking $1,775,000* by 
December. A total of 111 seats were bought during 
2006, compared to 104 in 2005. Of the total 111 
seats, 95 were bought for more than $1,000,000. 

CBOE’s seats increased 485% from the beginning 
of 2005 to the end of 2006. This positive trend may 
be attributed to the vibrancy of the overall “exchange 
space” sector.

 *On March 12, 2007, a CBOE seat was sold for a new all-time 

record high of $2,270,000.

Creating Business Opportunities

Shifting the emphasis of CBOE’s corporate business 
model to a for-profit operational mode has driven 
the Exchange to more readily seek new business 
opportunities, whether in the form of offering new 
products and services, or in searching for ways to 
generate additional revenue streams. 

Stock Exchange Created 
At a press conference in New York on July 27, 2006, 
CBOE announced the formation of the CBOE Stock 
Exchange (CBSX). CBOE partnered with Interactive 
Brokers Group, LLC; LaBranche & Co Inc.; 
Susquehanna International Group, LLP; and VDM 
Chicago, LLC in forming CBSX. 

CBSX is designed to extend the benefits of  
CBOE’s successful options market model to the  
stock world by allowing Designated Primary Market 
Makers (DPMs) and multiple, competing Remote 
Market Makers (RMMs) to provide two-sided liquidity 
in all stocks. CBSX is also ECN-like in nature: it is a 
fully electronic market that is Reg NMS-compliant 
and offers a price-time matching algorithm. By 
introducing a unique, yet proven, market model 
to the securities industry, CBSX will provide an 
attractive, alternative, trading destination for  
industry participants. 

CBSX was launched on March 5, 2007 and when  
its rollout is complete, CBSX will list 2,800 of the 
most-actively traded NYSE, NASDAQ, and AMEX  
listed securities. 

New Statistical Service Launched
In July 2006, CBOE also launched Market Data 
Express (MDX), a new statistical service to provide 
the most comprehensive historical trading data in 
the options industry. As a subsidiary of CBOE, MDX 
offers a wide range of historical options information 
on all equity, index and ETF options traded at CBOE 
dating back to 1990. 

Data requests to MDX are fully customizable,  
allowing users to select the market data criteria, 
time frame, and depth of information to be provided, 
and are available on a request or subscription basis. 

Post 10 on the CBOE trading floor, home to the new CBOE Stock Exchange.

Future additions to the service will provide historical 
information dating back 33 years to CBOE’s creation 
of the listed options market in 1973.

Alliance Formed with HedgeStreet
On February 22, 2006, CBOE announced a strategic 
alliance with HedgeStreet, Inc., an all-electronic 
futures exchange. CBOE’s alliance with HedgeStreet 
calls for the joint development of new products, the 
sharing of technology services, and the marketing 
and support of HedgeStreet’s innovative binary 
options and futures products. CBOE looks forward to 
launching a new wave of jointly developed, one-of-a-
kind products, while bringing HedgeStreet’s existing 
products to a broader audience.

HedgeStreet’s binary options are typically short-
term in nature, and are based on the value of the 
underlying instrument, with the payout determined 
by whether the option is in-the-money or not (they 
are sometimes referred to as “yes-no” or “cash-
or-nothing” options). HedgeStreet currently offers 
contracts on commodities such as gasoline, crude  
oil and gold. 

CBOE’s equity investment and alliance with 
HedgeStreet will serve to build momentum for  
binary options and this exciting new breed of  
futures products.

end, open interest stood at nearly 700,000 contracts. 
During May, total volume in VIX options topped one 
million contracts for the month. Unquestionably, VIX 
options have been one of the most successful new 
product launches in CBOE history. 

In May 2006, CBOE began disseminating information 
on the CBOE Russell 2000 Volatility Index. RVX 
tracks the volatility of the Russell 2000 Index  
(RUT), by measuring the implied volatility of near-
term RUT options. RVX was the fourth volatility 
index created by CBOE, joining the VIX, the CBOE 
DJIA Volatility Index (VXD), and the CBOE Nasdaq 
Volatility Index (VXN) in the Exchange’s suite of 
volatility benchmarks. 

New Benchmark Tracks Emerging  
“Exchange Space” Sector
In January 2006, CBOE unveiled the CBOE 
Exchange Index (EXQ), a new index that tracks  
the performance of publicly-traded financial 
exchanges in the U.S. Designed to quantify this 
popular new market, EXQ provides a composite 
measure of this emerging and rapidly growing new 
”exchange space” sector. By the end of the year, six 
different exchanges comprised the index. With the 
benchmark well established, CBOE listed options  
on EXQ in September. 

Options with Weekly and Quarterly Expirations
CBOE introduced new options with Weekly and 
Quarterly expirations to provide added flexibility 
in structuring positions within a portfolio. As their 
names imply, Weeklys are short-term options with 
a life of one week from launch to expiration, while 
Quarterlys have a life of three months. In 2006, 
CBOE listed Weekly options in Mini-SPX Index (XSP) 
and S&P 100 Index with European-style exercise 
(XEO). Quarterly options were listed on five ETFs: 
Nasdaq-100 Index Tracking Stock (QQQQ), Standard 
& Poor’s Depositary Receipts/SPDRs (SPY), 
DIAMONDS Trust, Series 1 (DIA), iShares Russell 
2000 Index Fund (IWM), and Energy Select  
SPDRs (XLE). 

BuyWrite Strategy 
A “BuyWrite,” also known as a covered call, is 
an investment strategy in which an investor buys 

New Products Generate “New” Volume
For more than three decades, innovation has defined 
CBOE’s legacy and has been a key to growing the 
Exchange’s business. Since its inception, CBOE 
has conceived many unique products that have 
shaped the world of risk management. And last year 
was no exception. In 2006, CBOE introduced nine 
breakthrough new products that added more than  
8.5 million contracts to the Exchange’s volume. 

Options on VIX: One of the Most Successful New 
Product Launches in CBOE History
CBOE has been the pioneer and leading authority in 
creating, defining and measuring the volatility space. 
The CBOE Volatility Index, or VIX, has been hailed 
as a revolutionary benchmark since its introduction 
in 1993. For more than a decade, VIX has been 
the preeminent barometer of market volatility and 
investor sentiment. Derived from real-time S&P 
500 Index option prices, VIX is designed to reflect 
investors’ consensus view of expected near-term 
stock market volatility over the next 30 days. VIX 
is closely followed, highly publicized, and is often 
referred to as the market’s “fear gauge.” 

In February 2006, the CBOE Volatility Index attained 
a new status when options on VIX began trading. The 
results were dramatic. VIX options averaged 23,491 
contracts per day in 2006; in just over ten months, 
a total of 5,050,638 contracts traded; and at year’s

OneChicago: 
Growing the Market for Single Stock Futures
OneChicago, the all-electronic exchange that 
relies on CBOEdirect as its trade engine, is a joint 
venture of CBOE, the Chicago Mercantile Exchange 
(CME) and the Chicago Board of Trade (CBOT). 
OneChicago continues to develop the market for the 
trading of single stock futures. Major educational 
and marketing initiatives were undertaken in 2006 
to accelerate the growth of security futures trading. 
The results were positive as a record 7,923,499 
security futures contracts traded at OneChicago 
during 2006, an increase of 43% over 2005’s total 
volume of 5.5 million contracts. Average daily volume 
on the year reached nearly 32,000 contracts per 
day. OneChicago presently lists 482 futures on single 
stocks, five Exchange Traded Funds, and seven 
OneChicago Select Indexes, a series of customer-
designed, narrow-based security index futures. 

In March 2006, Interactive Brokers Group, LLC, a 
leading electronic broker dealer, became an equity 
investor in OneChicago. The addition of IB into the 
OneChicago family of ownership brought additional 
technology and market maker support for single 
stock futures and helped to broaden the exchange’s 
customer base. 

CBOE Recognized as “Exchange of the Year”
In 2006, CBOE received three major awards in 
recognition of its continued industry leadership in 
groundbreaking, new product engineering. In May, 
CBOE was recognized as the “Exchange of the Year, 
North America” by Structured Products magazine; in 
September, Global Finance magazine named CBOE 
the “Best Derivatives Exchange in 2006;” and in 
December, VIX options were awarded the “Most 
Innovative Index Derivative Product” at the Super 
Bowl of Indexing Conference. Each of these awards 
cited CBOE’s “excellence and innovation” in creating 
new products and investor tools, most notably with 
the development of BuyWrite and Volatility indexes. 

a stock or a basket of stocks, and also sells call 
options that correspond to the stock or basket of 
stocks. Independent research has found that, over 
specific periods studied, a BuyWrite had slightly 
higher annualized returns — with significantly less 
volatility — than the corresponding index. 

CBOE now publishes data on five different 
BuyWrites, including the CBOE Russell 2000 
BuyWrite Index (BXR) and the CBOE S&P 500 2% 
OTM (Out-of-the-Money) BuyWrite Index (BXY), both 
of which were introduced last year. During 2006, all 
five CBOE BuyWrites posted increased returns for the 
year. Over the last two years, investors have allocated 
more than 20 billion dollars to forty new investment 
products that utilize BuyWrite Strategies. 

CBOE Futures Exchange: 
The Home of Volatility Futures
The CBOE Futures Exchange (CFE), CBOE’s 
all-electronic futures exchange powered by the 
CBOEdirect electronic trading system, was launched 
in March 2004 and now offers six different contracts, 
including futures on its flagship product, the CBOE 
Volatility Index (VIX), as well as CBOE S&P 500 
3-Month Variance (VT), CBOE DJIA Volatility Index 
(VXD), and the CBOE China Index (CX) futures. Two 
new contracts were listed in 2006: CBOE S&P 500 
12-Month Variance (VA) futures and CBOE S&P 500 
BuyWrite Index (BXM) futures.

Unique Market Model Differentiates CBOE

Hybrid Evolution Continues
During 2006, CBOE’s Hybrid Trading System 
continued to demonstrate why it is the most unique 
market model in the industry. The versatility of 
Hybrid provides a “best of both worlds” trading 
environment, allowing customers to choose how  
their orders are handled — either electronically or  
via open outcry. By year’s end, the majority of 
customers were opting for electronic trading as 
96 percent of all Hybrid orders were handled 
electronically with sub-second execution. However, 
the remaining 4 percent of the orders that were 
conducted in open outcry represented nearly one-
third (29%) of all Exchange volume. 

Ongoing systems upgrades ensure that the 
CBOE Hybrid Trading System continues to offer 
unparalleled trading choice in both types of trading 
venues. In February 2006, CBOE created the Hybrid 
Agency Liaison (HAL), which automated the handling 
of certain types of orders that had previously 
been subject to manual handling. And later in the 
year, CBOE became the first exchange to offer an 
electronic price improvement auction for complex 
(multi-legged) orders in the form of Complex Order 
Auction (COA). 

Growth of Remote Market Making 
CBOE’s Remote Market Maker Program continued 
to expand throughout 2006. The number of Remote 
Market Makers (RMMs) and Electronic Designated 
Primary Market Makers (e-DPMs) — those CBOE 

members or member firms who stream quotes and 
trade electronically from remote locations — totaled 
fifty RMMs and six e-DPMs by the end of the year.  
The volume generated from these new electronic 
members grew substantially: from 6.6 million 
contracts or 35% of all Hyrbid volume during 
December 2005 to 15.0 million contracts and 59% 
in December 2006. The RMM program has been 
successful in expanding the universe of market 
participants at CBOE, while the consolidation of 
off-floor RMM quotes with those of in-crowd market 
participants has resulted in deeper, more liquid 
markets at CBOE. 

Expanding Index Offerings on Hybrid 
All of CBOE’s equity options have been listed on 
Hybrid since the end of 2005, and last year, CBOE 
focused on expanding the number of index and 
Exchange Traded Fund options available for trading 
on Hybrid. During the course of 2006, thirty were 
added, including major indexes such as the Russell 
2000 Index (RUT), CBOE Volatility Index (VIX), 
Jumbo Dow Jones Industrial Average Index (DXL) 
and S&P Small Cap 600 Index (SML). Also added 
were popular ETFs such as iShares Russell 2000 
Index Fund (IWM) and iShares S&P 100 Index Fund 
(OEF). With the additions of Nasdaq-100 Index 
options (NDX) and S&P 100 Index options with 
European-style exercise (XEO) in January 2007, 
121 of CBOE’s 124 index and ETF options are now 
available for trading via Hybrid.

Leading the Industry in Advocacy and Education

The Primary Proponent for Expanded Portfolio 
Margining Rules
In December 2006, the SEC approved amendments 
to CBOE’s rules allowing for expanded portfolio 
margining of customer accounts. For more than five 
years, CBOE was the driving force in moving this 
initiative through Congress, the Commodity Futures 
Trading Commission (CFTC) and the SEC. The new 
rules generally align the amount of margin money 
required in a customer’s account to the risk of the 
portfolio as a whole, whereas current practice is to 
require margin based on set formulas for various 
strategies. The new rules also expand the scope of 
products eligible for portfolio margining to include 
equities, equity options, narrow-based index options, 
certain security futures products (i.e. single stock 
futures and options on single stock futures), and 
unlisted derivatives. 

Other markets around the world already allow for 
similar portfolio margining. Thus, the SEC’s approval  
of the new rules helps to level the playing field and 
will make the U.S. equities markets more competitive 
with our global counterparts. CBOE anticipates the 
new rules, which became effective on April 2, 2007, 
will modernize our marketplace.

CBOE Tabbed to Lead Industry Surveillance
CBOE, along with the American Stock Exchange, 
Boston Stock Exchange, International Securities 
Exchange, NYSE Arca, (formerly the Pacific 
Exchange) and Philadelphia Stock Exchange, formed 
the Options Regulatory Surveillance Authority 
(ORSA) in 2006. ORSA was conceived to enhance 
the effectiveness and efficiency of regulation of the 
national options market system, as well as that of 
each of the individual options markets, by facilitating 
the sharing of resources and information. 

As the developer of the industry’s most advanced 
surveillance technology, CBOE was chosen to lead 
and coordinate the industry’s surveillance efforts for 
tracking possible insider trading infractions. While 
CBOE is conducting the insider trading surveillance 
and investigations on behalf of the ORSA operations, 
the six exchanges share equal authority in regulation, 
and jointly plan, develop, and operate ORSA’s 
regulatory systems and facilities. 

Events like this “VIX and Volatility Trading” seminar exemplify CBOE’s 
commitment to investor education.

The Premier Source for Options Education 
The Options Institute, the educational arm of CBOE, 
is the leading authority for options education. 
Founded in 1985, it continues to play an integral 
role in aiding the tremendous growth of our industry. 
Each year, The Options Institute conducts hundreds 
of classes worldwide, educating thousands of 
investors, brokers, advisors and regulatory personnel. 

For five years running, cboe.com has received a  
“Best of the Web” honor from Forbes.com, and 
for three consecutive years, a “Top Investment 
Websites” designation from the American Association 
of Individual Investors®. Last year, more than 
800,000 unique visitors clicked on cboe.com each 
month for options news and information. 

Some of the most popular features on cboe.com 
are The Options Institute’s online tutorials, courses 
and webcasts. The self-guided tutorials teach the 
basics of options, while the online courses explore 
concepts and strategies. The webcasts offer live 
presentations of options-related topics and enable 
online interaction with the presenter. During 2006, 
enrollment in CBOE’s online courses increased 50% 
to 5,500 participants. 

In 2006, cboe.com’s popular CBOE-TV experienced 
huge viewership gains during its first full year of 
operation. The free web-based streaming video 
service, which provides daily trading insights, market 
recaps, and coverage of events and news from 
CBOE’s trading floor, saw its total audience increase 
by more than 450% to 300,000+ viewers per month.

Communicating a Message

“Accept No Substitute”
Leading brands have a reason to exist. They are  
born from a new way of thinking about problems.  
They create opportunities. They have a story to tell. 
CBOE is such a brand. The Exchange innovates 
and leads. It is nearly impossible to imagine a world 
without options because of what CBOE has done,  
not only since founding the industry in 1973, but  
for what it will continue to accomplish in the months 
and years ahead. 

In 2006, the Exchange developed the framework 
for an extensive branding initiative that will kick-
off during 2007 and illustrate CBOE’s position of 
industry leadership. More specifically, the message 
behind the campaign will communicate to the 
world that CBOE is a vital necessity in the options 
marketplace for which there is no substitute. 
To amplify this message, an extensive print and 
broadcast campaign will run in various financial 
media during the year. The reach of the campaign 
will also be extended through the use of outdoor  
and online advertising. 

The “Accept No Substitute” campaign is scheduled  
to run in a variety of business publications including  
The Wall Street Journal, Barron’s and Forbes. 
Additionally, a thirty-second television commercial 
will air on the CNBC and Bloomberg networks at 
various times throughout 2007.

2006 Financial Summary

CBOE generated record net income of $42.1 million in 2006 versus $10.9 million in the prior year.

Record trading volume of 2.7 million contracts per day in 2006, compared to the prior record of 1.9 million 
contracts per day established in 2005, was the main reason for the strong financial results. 

The significant growth in 2006 trading volume (44%) versus the prior period was the main reason current 
year revenues were $54.9 million (27%) higher than 2005. Fee reductions and fee caps saved our customers 
and members $45.7 million in 2006 versus $31.6 million in 2005. 

Expenses were $2.8 million higher than the prior period mainly due to higher employee costs ($5.1 million), 
outside services ($2.1 million) and royalty fees ($1.6 million). Employee costs were higher in 2006 mainly due  
to higher severance expense ($3.4 million). Outside services increased mainly due to higher legal fees related  
to demutualization and other legal matters. Royalty fees increased in 2006 due to record trading volume in  
certain licensed products.

CBOE received a $7.1 million refund in 2006 as a result of a resettlement of a year 2000 class action 
settlement. In 2000, CBOE paid $16.0 million to settle a class action matter. See financial statements Note 6 
for details. The $7.1 million refund is included as a reduction to other expenses.

Capital spending in 2006 amounted to $28.7 million. Investments were primarily in the Systems Division 
related to increased capacity, Hybrid Trading System enhancements, a new disaster recovery site and other 
trading systems enhancements. 

In 2006, CBOE invested $3.8 million in HedgeStreet, Inc., contributed $1.2 million to OneChicago, LLC due to 
a capital call and purchased one CBOE membership ($1.4 million). 

The Exchange received $3.0 million from the National Stock Exchange (“NSX”) in 2006 related to a 
Termination of Rights Agreement (“TORA”). See financial statements Note 2 for details of the TORA. 

Retained earnings increased to $162.0 million and total members’ equity at December 31, 2006 was  
$183.4 million. At year’s end, the Exchange was debt-free with working capital of $94.1 million.

Chicago Board Options Exchange, Incorporated and Subsidiaries 
For the years ended December 31, 2006 and 2005

1. summary of significant accounting policies 
Nature of Business — The Chicago Board Options Exchange, Incorporated and Subsidiaries (“CBOE”) is a registered securities 
exchange, subject to oversight by the Securities and Exchange Commission (“SEC”). CBOE’s principal business is providing a 
marketplace for trading equity and index options.

Basis of Presentation — The consolidated financial statements include the accounts and results of operations of the Chicago Board 
Options Exchange, Incorporated and its wholly-owned subsidiaries, Chicago Options Exchange Building Corporation, CBOE, LLC and 
CBOE Futures Exchange, LLC. Inter-company balances and transactions are eliminated. 

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States of America requires management to make estimates and assumptions that affect the amounts of assets and liabilities, 
disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses during the reporting period. Actual 
results could differ from those estimates.

Revenue Recognition — Transaction Fees revenue is considered earned upon the execution of the trade and is recognized on a 
trade date basis. In the event members pay for services in a lump-sum payment, revenue is recognized as services are provided. 
Other Member Fees revenue is recognized during the period the service is provided. The Options Price Reporting Authority 
(“OPRA”) income is allocated based upon the market share of the OPRA members and is received quarterly. Estimates of OPRA’s 
quarterly revenue are made and accrued each month. Regulatory Fees are predominately received in the month of December and 
are amortized monthly to coincide with the services rendered during the period July through June.

Cash and Cash Equivalents — Cash and cash equivalents include highly liquid investments with maturities of three months or less 
from the date of purchase.

Investments — All investments are classified as available-for-sale and are reported at fair value with unrealized gains and losses 
reported as a component of other comprehensive income within members’ equity, in accordance with Statement of Financial 
Accounting Standards (“SFAS”), No. 115, Accounting for Certain Investments in Debt and Equity Securities.

Accounts Receivable — Accounts receivable consist primarily of transaction, marketing and other fees receivable from The Options 
Clearing Corporation (“OCC”), and CBOE’s share of distributable revenue receivable from OPRA.

Investments in Affiliates — Investments in affiliates represent investments in OCC, OneChicago, LLC (“OneChicago”), The National 
Stock Exchange (“NSX”) and HedgeStreet, Inc. 

The investment in OCC (20% of its outstanding stock) is carried at cost because of CBOE’s inability to exercise significant influence.

CBOE owns 8,424 shares of Class A stock (4.98% of the total outstanding) and 39,312 shares of Class B stock (100% of the total 
outstanding) of NSX as of December 31, 2006. As of July 1, 2006, CBOE began accounting for the investment in NSX using the 
cost method as NSX reacquired stock from CBOE and sold additional stock to new investors, thereby diluting CBOE’s ownership 
percentage (see Note 2). 

CBOE accounts for the investment in OneChicago (approximately 24% of its outstanding stock) under the equity method due to the 
lack of effective control over operating and financing activities. 

The investment in HedgeStreet, Inc. (17.6% of its capital stock) is carried at cost because of CBOE’s inability to exercise significant 
influence.

Investments in affiliates are reviewed to determine whether any events or changes in circumstances indicate that the investments 
may be other than temporarily impaired. 

In the event of impairment, CBOE would recognize a loss for the difference between the carrying amount and the estimated fair 
value of the equity method investment.

Property and Equipment — Property and equipment are carried at cost, net of accumulated depreciation. Depreciation on building,  
furniture and equipment is provided on the straight-line method. Estimated useful lives are 40 years for the building and five to 
ten years for furniture and equipment. Leasehold improvements are amortized over the lesser of their estimated useful lives or the 
remaining term of the applicable leases.

CBOE’s long-lived assets are subject to impairment testing in accordance with SFAS No. 144 whenever events or changes in 
circumstances indicate that the carrying amount may not be recoverable. CBOE bases its evaluation on such impairment indicators 
as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements, as well 
as other external market conditions or factors that may be present. In the event of an impairment, CBOE recognizes a loss for the 
difference between the carrying amount and the estimated fair value of the asset.

Data Processing Software & Software Development Work in Progress — Data processing software and software development work 
in progress during the application development stage are capitalized in accordance with Statement of Position 98-1 Accounting 
for the Costs of Computer Software Developed or Obtained for Internal Use and are carried at cost. Software development work in 
progress is reclassified to data processing software when the software is ready for its intended use. Data processing software is 
amortized over five years using the straight-line method commencing with the date the software is put in service.

Income Taxes — Income taxes are determined using the liability method, under which deferred tax assets and liabilities are recorded 
based on differences between the financial accounting and tax bases of assets and liabilities.

Deferred Revenue — Deferred revenue represents amounts received by CBOE for which services have not been provided.

Recent Accounting Pronouncements — In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 
No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109, which clarifies the 
accounting for uncertainty in tax positions. FIN 48 seeks to reduce the diversity in accounting practices used in regards to uncertain 
tax positions by prescribing a recognition threshold and measurement criteria for benefits related to income taxes. The provisions of 
FIN 48 are effective for all reporting periods beginning after December 15, 2006. The impact of the adoption of FIN 48 on CBOE’s 
financial position and results of operations is being evaluated.

24  CBOE  2006

notes to consolidated financial statements (continued)

In September 2006, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 157, Fair Value Measurements, 
which establishes a framework for measuring fair value under other accounting pronouncements that require fair value 
measurements and expands disclosures about such measurements. SFAS No. 157 does not require any new fair value 
measurements. Instead, it creates a consistent method of calculating fair value measurements to address non-comparability of 
financial statements containing fair value measurements utilizing different definitions of fair value. SFAS No. 157 is effective for 
financial statements issued for fiscal years beginning after November 15, 2007. It is not anticipated that the adoption of SFAS No. 
157 will have a significant impact on CBOE’s financial position and results of operations.

In September 2006, the FASB issued SFAS No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement 
Plans—an amendment of FASB Statements No. 87, 88, 106, and 132(R) which requires the overfunded or underfunded status 
of a defined benefit postretirement plan to be recognized in the statement of financial position and changes in that funded status 
to be recognized in the year of change in comprehensive income. SFAS No. 158 also requires that plan assets and obligations 
be measured at year-end and requires certain disclosures. CBOE is required to recognize the funded status of a defined benefit 
postretirement medical plan and to make required disclosures as of our fiscal year ending December 31, 2007, however we have 
elected to adopt the provisions of SFAS No. 158 in 2006. 

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities — Including 
an Amendment of FASB Statement No. 115, which permits, at specified election dates, measurement of eligible items at fair value. 
SFAS No. 159 does not require any new fair value measurements. SFAS No. 159 is effective for financial statements issued for fiscal 
years beginning after November 15, 2007. Early adoption is permitted provided that SFAS No. 157 is concurrently adopted. It is not 
anticipated that the adoption of SFAS No. 159 will have a significant impact on CBOE’s financial position and results of operations.

2. investments in affiliates
CBOE and NSX executed a Termination of Rights Agreement (“TORA”), on September 27, 2004. Pursuant to the TORA, NSX 
will purchase 153 (94%) of NSX certificates of proprietary membership currently owned by CBOE. Certificates of proprietary 
membership will be surrendered by CBOE, and NSX will pay CBOE a total of $11 million over a period of four years on the 
anniversary of the initial closing date, subject to NSX minimum working capital levels after deducting the cost of buying the 
certificates. CBOE will ultimately retain nine certificates of proprietary membership (10% of the total outstanding certificates of 
proprietary membership). After the sale of 153 certificates, CBOE will account for its remaining investment in NSX on the cost 
basis. The initial closing transaction was held on January 18, 2005. On this date, CBOE surrendered 69 certificates of proprietary 
membership, and NSX paid $5.0 million to CBOE. CBOE also gave up three of six seats on the NSX Board on the date of the initial 
closing. CBOE’s percentage of ownership of the remaining NSX outstanding certificates of proprietary membership was reduced 
to 54.7% after the initial closing. On March 10, 2006, CBOE exercised its first put right under the TORA. On this date, CBOE 
surrendered an additional 21 certificates of proprietary membership, and NSX paid CBOE $1.5 million. CBOE’s percentage of 
ownership of the remaining NSX outstanding certificates of proprietary membership was reduced to 48.3% after the March 10, 
2006 exercise of its first put right. On June 22, 2006, NSX converted from a membership organization to a stock-based corporation. 
In the demutualization, the certificates of proprietary membership held by CBOE were converted to 8,424 shares (9.96%) of Class 
A voting stock of NSX Holdings, Inc. and 58,968 shares (100%) of Class B non-voting stock of NSX Holdings, Inc. On September 
5, 2006, NSX issued a total of 87,010 Class A voting common stock to six investors. CBOE did not invoke its anti-dilution rights and 
as a result, CBOE’s ownership percentage of Class A voting common stock was reduced to 4.98%. On September 15, 2006, NSX 
exercised a call pursuant to the TORA and purchased 19,656 shares of Class B stock and paid CBOE $1.5 million. At December 
31, 2006, CBOE’s investment in NSX was $3.7 million which consisted of the 8,924 Class A voting shares and 39,312 Class B non-
voting shares. CBOE’s representation on the NSX board has decreased to one representative as a result of the most recent decrease 
in ownership percentage of NSX by CBOE.

CBOE, Interactive Brokers Group LLC (“IBG”), the Chicago Mercantile Exchange Holdings, Inc. and the Board of Trade of the City of 
Chicago, Inc. (the “CBOT”), are partners in OneChicago, a joint venture created to trade single stock futures. Certain OneChicago 
employees also have minority interests in the joint venture. OneChicago is a for-profit entity with its own management and board 
of directors, and is separately organized as a regulated exchange. CBOE accounts for its interest in OneChicago under the equity 
method of accounting. On March 15, 2006, IBG made an investment for a 40% interest in OneChicago. As a result, CBOE’s 
ownership decreased from approximately 40% to 24%. CBOE contributed $1.2 million and $0.8 million in capital to OneChicago 
during the years ended December 31, 2006 and 2005, respectively. At December 31, 2006, CBOE’s investment in OneChicago 
was $4.8 million. CBOE’s investment increased by $4.3 million as a result of IBG’s investment as discussed above. CBOE had a 
receivable due from OneChicago of $0.5 million and $0.9 million at December 31, 2006 and 2005, respectively.

On February 10, 2006, CBOE invested $2.0 million in HedgeStreet, Inc. CBOE holds one of six HedgeStreet, Inc. board seats. On 
December 29, 2006, CBOE invested an additional $1.8 million in HedgeStreet, Inc. for Series D Preferred Stock. CBOE owns a 
total of 17.7% of HedgeStreet Inc. voting common and preferred shares. CBOE had a receivable due from HedgeStreet, Inc. of $0.1 
million at December 31, 2006 for certain service level agreements. 

3. related parties 
CBOE collected transaction and other fees of $298.9 million and $191.2 million by drawing on accounts of CBOE’s members held 
at OCC for the years ended December 31, 2006 and 2005. The amount collected included $96.5 million and $42.1 million of 
marketing fees during the years ended December 31, 2006 and 2005, respectively. CBOE had a receivable due from OCC of $23.0 
million and $15.2 million at December 31, 2006 and 2005, respectively.

CBOE incurred rebillable expenses on behalf of NSX for expenses such as employee costs, computer equipment and office space of 
$2.9 million and $3.8 million during the years ended December 31, 2006 and 2005, respectively. CBOE had a receivable from NSX 
of $0.9 million and $0.9 million at December 31, 2006 and 2005, respectively.

OPRA is a committee administered jointly by the six options exchanges and is authorized by the SEC to provide consolidated options 
information. This information is provided by the exchanges and is sold to outside news services and customers. OPRA’s operating 
income is distributed among the exchanges based on their relative volume of total transactions. Operating income distributed 
to CBOE was $20.0 million and $16.7 million during the years ended December 31, 2006 and 2005, respectively. CBOE had a 
receivable from OPRA of $5.4 million and $4.4 million at December 31, 2006 and 2005, respectively.

25  CBOE  2006

notes to consolidated financial statements (continued)

CBOE incurred administrative expenses of $13,000 and $3,600 for its affiliate, the Chicago Board Options Exchange Political Action 
Committee (the “Committee”), during the years ended December 31, 2006 and 2005, respectively. The Committee is organized 
under the Federal Election Campaign Act as a voluntary, not-for-profit, unincorporated political association. The Committee is 
empowered to solicit and accept voluntary contributions from members and employees of CBOE and to contribute funds to the 
election campaigns of candidates for federal offices.

4. leases 
CBOE leases office space with lease terms remaining from thirteen months to twenty-nine months as of December 31, 2006. 
Rent expenses related to leases for the twelve months ended December 31, 2006 and 2005 were $0.6 million and $0.8 million, 
respectively. Future minimum lease payments under these non-cancellable operating leases are as follows at December 31, 2006 
(in thousands):

5. employee benefits
Eligible employees participate in the Chicago Board Options Exchange SMART Plan (“SMART Plan”). The SMART Plan is a defined 
contribution plan, which is qualified under Internal Revenue Code Section 401(k). CBOE contributed $4.0 million and $4.3 million to 
the SMART Plan for the years ended December 31, 2006 and 2005, respectively.

Eligible employees may participate in the Supplemental Employee Retirement Plan (“SERP”), and Deferred Compensation Plan. The 
SERP and Deferred Compensation Plan are defined contribution plans that are nonqualified by Internal Revenue Code regulations. 
CBOE contributed $1.3 million and $1.3 million to the SERP for the years ended December 31, 2006 and 2005, respectively.

CBOE also has a Voluntary Employees’ Beneficiary Association (“VEBA”). The VEBA is a trust, qualifying under Internal Revenue 
Code Section 501(c)(9), created to provide certain medical, dental, severance, and short-term disability benefits to employees of 
CBOE. Contributions to the trust are based on reserve levels established by Section 419(a) of the Internal Revenue Code. During the 
years ended December 31, 2006 and 2005, CBOE contributed $5.3 million and $5.6 million, respectively, to the trust.

CBOE has a postretirement medical plan for certain current and former members of senior management. SFAS No. 158 changed 
the accounting rules for reporting the funded status of retirement and other postretirement benefits plans. The funded status of 
such plans is required to be recognized on the balance sheet with a corresponding after-tax adjustment to accumulated other 
comprehensive income. Retroactive application of this accounting rule is prohibited. Therefore, 2006 data is presented as required 
by SFAS No. 158 and 2005 data is presented as required under the accounting rules prior to SFAS No. 158. The adoption of 
SFAS No. 158 in 2006 had no effect on the computation of net periodic benefit expense for CBOE’s postretirement benefits. 
The incremental effect of applying SFAS No. 158 on individual line items on CBOE’s consolidated balance sheet as of December 
31, 2006 was as follows: CBOE recorded a $1.3 million liability related to the actuarially computed underfunded status of our 
postretirement medical plan, of which $0.8 million was recorded in other comprehensive loss as a reduction to members’ equity 
and $0.5 million was recorded as a deferred income tax asset. CBOE estimates that postretirement benefits expense for the year 
ended December 31, 2007 will include expense of $0.1 million, resulting from the amortization of its related accumulated actuarial 
expense included in Accumulated Other Comprehensive Loss at December 31, 2006.

6. commitments and contingencies 
The CBOE is currently a party to the following legal proceedings:

Litigation with Respect to the Restructuring Transaction 
On August 23, 2006, the CBOE and its directors were sued in the Court of Chancery of the State of Delaware, New Castle County, 
by the CBOT, CBOT Holdings and two members of the CBOT who purport to represent a class of individuals (“exercise members”), 
who are, or have the right to become, members of the CBOE pursuant to the Exercise Right granted to CBOT members pursuant to 
paragraph (b) of Article Fifth of the CBOE’s certificate of incorporation. Plaintiffs seek a judicial declaration that exercise members 
are entitled to receive the same consideration in the CBOE’s restructuring transaction as all other CBOE members, and plaintiffs 
also seek an injunction to bar CBOE and CBOE’s directors from issuing any stock to CBOE members as part of the restructuring 
transaction, unless exercise members receive the same stock and other consideration as other CBOE members. On October 2, 
2006, the CBOE and the individual director defendants moved to dismiss the complaint on the grounds that the complaint failed to 
present a ripe controversy between the parties, in that the CBOE had not yet made any decisions about the terms of the potential 
restructuring transaction or about the nature or the amount of the consideration that the members of the supposed class will receive 
in connection with that restructuring transaction, and the Court lacked jurisdiction over certain individuals.

On October 17, 2006, CBOT Holdings announced its intention to be acquired by CME Holdings (the “CME/CBOT Transaction”). In 
response to that announcement, the CBOE determined that the proper interpretation of Article Fifth(b) was that, upon the closing 
of the CME/CBOT Transaction, no one would qualify as a CBOT “member” for purposes of Article Fifth(b) or therefore as a person 
eligible to be an exerciser member of the CBOE. The CBOE submitted its interpretation for review and approval by the SEC on 
December 12, 2006, as required because of the CBOE’s status as a national securities exchange, and amended that submission 
on January 16, 2007. On January 4, 2007, plaintiffs filed a second amended complaint that challenged the CBOE’s interpretation 
of Article Fifth(b). On January 11, 2007, plaintiffs submitted a motion for summary judgment on their claims. In addition to 
continuing to assert their claims about the amount of consideration to which exercise members would be entitled as part of the 
CBOE restructuring transaction, plaintiffs sought a declaratory judgment and an injunction to prevent the CBOE from implementing 
the interpretation of Article Fifth(b) that the CBOE had filed with the SEC and a declaration that CBOE’s board breached its fiduciary 
duties by approving that interpretation. On January 16, 2007, the CBOE and the director defendants moved to dismiss the second 
amended complaint to the extent it challenges the CBOE’s interpretation, on the ground that the SEC’s jurisdiction to consider such 

26  CBOE  2006

 
  
 
 
  
 
  
 
 
  
 
 
  
notes to consolidated financial statements (continued)

interpretations of Article Fifth(b) preempts any state law challenge to that interpretation. In this motion, defendants further moved to 
dismiss or stay consideration of plaintiffs’ claims regarding the consideration to which exercise members otherwise would be entitled 
until it is known whether the CME/CBOT Transaction will close before the CBOE’s restructuring transaction on the grounds that such 
claims remain unripe for judicial determination. The court has not decided either defendants’ motion to dismiss or plaintiffs’ motion 
for summary judgment.

Class Action Litigation 
In September 2000, the CBOE reached an agreement in principle to settle a consolidated civil class action lawsuit filed against the 
CBOE and other U.S. options exchanges and certain market maker firms. The CBOE agreed to pay $16.0 million, which has been 
paid in full and held in escrow pending approval of the settlement agreement by the U.S. District Court for the Southern District 
of New York. In October 2005, the CBOE and other settling parties reached a revised settlement that resolved certain disputes 
concerning the interpretation of certain provisions of the original settlement agreement. As a result of the revised settlement, the 
CBOE’s settlement amount was reduced to $9.3 million. In February 2006, the U.S. District Court preliminarily approved the revised 
settlement, and CBOE received a refund on its original settlement amount of $7.1 million, including accrued interest. The district 
court granted final approval to the settlement, and entered final judgment in the case, in December 2006. The deadline to appeal 
the settlement passed on January 12, 2007, and no appeals were filed.

Last Atlantis Litigation 
On November 7, 2005, an amended and consolidated complaint, which we refer to as the “consolidated complaint,” was filed 
on behalf of Last Atlantis Capital LLC, Lola L.L.C., Lulu L.L.C., Goodbuddy Society L.L.C., Friendly Trading L.L.C., Speed Trading, 
LLC, Bryan Rule, Brad Martin and River North Investors LLC in the U.S. District Court for the Northern District of Illinois against 
the CBOE, three other options exchanges and 35 market maker defendant groups (the “Specialist Defendants”). The consolidated 
complaint combined complaints that recently had been filed by Bryan Rule and Brad Martin with an amendment of a previously 
dismissed complaint, which we refer to as the “original complaint,” that originally had been brought by a number of the other 
plaintiffs. The consolidated complaint raised claims for securities fraud, breach of contract, common law fraud, breach of fiduciary 
duty, violations of the Illinois Consumer Fraud and Deceptive Trade Practices Act and tortuous interference with plaintiffs’ business 
and contracts. The previously dismissed original complaint also had brought claims under the antitrust laws, and the dismissal 
of those claims remains subject to appeal. With regard to the CBOE, the consolidated complaint alleged that the CBOE and the 
other exchange defendants knowingly allowed the specialist defendants to discriminate against the plaintiffs’ electronic orders or 
facilitated such discrimination, failed adequately to investigate complaints about such alleged discrimination, allowed the specialist 
defendants to violate CBOE’s Rules and the rules of the SEC, failed to discipline the specialist defendants, falsely represented and 
guaranteed that electronically entered orders would be executed immediately and knowingly or recklessly participated in, assisted 
and concealed a fraudulent scheme by which the defendants supposedly denied the customers the electronic executions to which 
they claim they were entitled. Plaintiffs sought unspecified compensatory damages, related injunctive relief, attorneys’ fees and 
other fees and costs. On September 13, 2006, the Court dismissed the consolidated complaint in its entirety and entered judgment 
in favor of all defendants. On September 29, 2006, plaintiffs filed a motion to reconsider in which they requested that the court 
either amend or vacate the September 13 judgment and allow them to file a further amended consolidated complaint. Plaintiffs 
simultaneously appealed the dismissal of both the consolidated complaint and the original complaint. On March 22, 2007, the Court 
denied plaintiffs’ request to reconsider the dismissal of the claims against CBOE and held that the prior dismissal of those claims, 
with prejudice, would stand. The Court, however, granted plaintiffs’ motion to reconsider the dismissal of the claims against the 
Specialist Defendants and ordered plaintiffs to file another amended complaint asserting only their claims against the Specialist 
Defendants. While the dismissal of the claims against CBOE is ultimately subject to appeal, that appeal cannot proceed until after 
the Court resolves all of the claims against the Specialist Defendants.

Index Options Litigation 
On November 2, 2006, the ISE and its parent company filed a lawsuit in federal court in the Southern District of New York against 
The McGraw-Hill Companies, Inc. (“McGraw-Hill”) and Dow Jones & Co. (“Dow Jones”), the owners, respectively, of the S&P 500 
Index and the DJIA, which are the basis for index options, or “SPX options” and “DJX options,” respectively, that the CBOE trades 
pursuant to exclusive licenses from McGraw-Hill and Dow Jones. The CBOE is not a party in this lawsuit. The ISE seeks a judicial 
declaration that it may list and trade SPX and DJX options without a license and without regard to the CBOE’s exclusive licenses 
to trade options on those indexes, on the ground that any state-law claims based on the unlicensed listing of SPX and DJX options 
allegedly would be preempted by the federal Copyright Act and because McGraw-Hill and Dow Jones supposedly cannot state an 
actionable copyright claim. McGraw-Hill and Dow Jones filed a motion to dismiss this action on December 22, 2006, on the ground 
that there is no federal jurisdiction over this dispute. This motion has not been decided. Consistent with the jurisdictional position of 
McGraw-Hill and Dow Jones, those parties joined with the CBOE to file a state court action in Illinois on November 15, 2006 against 
the ISE and OCC (the “Illinois action”). In the Illinois action, the CBOE and the other plaintiffs seek a judicial declaration that the 
ISE may not list, or offer trading of, SPX or DJX options because of both the proprietary rights of McGraw-Hill and Dow Jones in the 
underlying indexes and the CBOE’s exclusive license rights to trade such options. The Illinois action alleges that the ISE’s threatened 
action would misappropriate the proprietary interests of McGraw-Hill and Dow Jones and the exclusive license rights of the CBOE, 
would interfere with the CBOE’s prospective business relationships with its members firms and customers and would constitute 
unfair competition. On December 12, 2006, the ISE removed the Illinois action to federal court in the Northern District of Illinois. On 
December 15, 2006, the CBOE and the other plaintiffs in the Illinois action moved to remand the matter to the Illinois state court on 
the ground that there is no federal jurisdiction over the claims. The federal court granted the motion to remand the Illinois action to 
state court, where it is now pending. The ISE moved to dismiss the Illinois action on the alternative grounds of inconvenient forum 
and the prior-pending suit it filed in New York. The CBOE and the other plaintiffs are opposing the ISE’s motion and the court is 
scheduled to hear oral argument on May 15, 2007.

Patent Litigation 
On November 22, 2006, the ISE filed an action in federal court in the Southern District of New York claiming that CBOE’s Hybrid 
Trading System infringes ISE’s patent directed towards an automated exchange for trading derivative securities. On January 31, 
2007, the CBOE filed an action in federal court in the Northern District of Illinois seeking a declaratory judgment that the ISE patent 
that is the subject of the action in New York, and two other patents that the ISE had raised in communications with the CBOE, are 
either not infringed and/or not valid and/or not enforceable against the CBOE. The ISE has not yet responded to this complaint.  
On February 5, 2007, the CBOE filed a motion to transfer the matter pending in the Southern District of New York to federal court 
in the Northern District of Illinois. Although briefing on the motion to transfer concluded on February 27, 2007, the venue issue 
remains pending.

27  CBOE  2006

notes to consolidated financial statements (continued)

Other 
As a self-regulatory organization under the jurisdiction of the SEC, and as a designated contract market under the jurisdiction of the 
CFTC, CBOE and CFE are subject to routine reviews and inspections by the SEC and the CFTC. CBOE is also currently a party to 
various other legal proceedings.

It is management’s belief that the expected outcome of any of the legal proceedings to which CBOE is currently a party will not 
have a material impact on the consolidated financial position or results of operations of CBOE; however, litigation is subject to many 
uncertainties, and the outcome of individual litigated matters is not predictable with assurance.

7. marketing fee 
CBOE facilitates the collection and payment of marketing fees assessed on certain trades with payment accepting firms. Funds are 
made available to Designated Primary Market Makers and Preferred Market Makers for order flow marketing. As of December 31, 
2006 and 2005, respectively, amounts held by CBOE on behalf of others included an accounts receivable balance of $8.0 million 
and $3.6 million.

8. income taxes 
A reconciliation of the statutory federal income tax rate to the effective income tax rate, for the years ended December 31, 2006 and 
2005 is as follows:

Statutory federal income tax rate 
State income tax rate, net of federal income tax effect 
Other permanent differences, net 
Effective income tax rate 

2006  
 35.0%  
4.8%  
 1.7%  
   41.5%  

The components of income tax expense for the years ended December 31, 2006 and 2005 are as follows (in thousands):

Current: 
Federal

Total current 
Deferred:

$  20,366

$  23,718

Deferred income taxes arise principally from temporary differences relating to the use of accelerated depreciation methods 
for income tax purposes, capitalization of internally developed software, funding of the VEBA trust, new partner investment in 
OneChicago and undistributed earnings from CBOE’s investment in NSX.

9. deferred revenue
A fixed transaction fee program was in effect for the period October 1, 2004 through December 31, 2006. Under the 2006 
program, Designated Primary Market-Makers (“DPMs”), electronic DPMs (“e-DPMs”), and Remote Market Makers (“RMMs”) could 
elect to pay a fixed annual fee instead of being assessed transaction fees on a per contract basis for their DPM, e-DPM, and RMM 
transactions in equity option classes. Six DPMs participated in the 2006 fixed fee program. The prepayment of the 2006 transaction 
fees totaled $13.5 million during the first quarter of 2006. This amount was amortized and recorded as transaction fees revenue 
each month during 2006. 

Under the 2005 fixed transaction fee program, Designated Primary Market-Makers (DPMs) and electronic DPMs (e-DPMs) could 
elect to pay a fixed annual fee instead of being assessed transaction fees on a per contract basis for their DPM, e-DPM, and Remote 
Market Maker transactions only in equity option classes. Six DPMs participated in the 2005 fixed fee program. The prepayment 
of the 2005 associated transaction fees totaled $10.5 million as of December 31, 2004, was recorded as deferred revenue. This 
amount was amortized and recorded as transaction revenues monthly during 2005. 

In December 2006 and 2005 CBOE collected $8.2 million and $7.9 million, respectively, representing annual regulatory fees 
amortized over the twelve-month period of July through June. The amount included in deferred revenue as of December 31, 2006 
and 2005 totaled $4.1 million and $3.9 million.

10. fair value of financial instruments 
SFAS No. 107, Disclosures About Fair Value of Financial Instruments, requires disclosure of the fair value of certain financial 
instruments. The carrying values of financial instruments included in assets and liabilities are reasonable estimates of their fair value 
due to their short-term nature.

notes to consolidated financial statements (continued)

11. purchase of chicago board of trade (cbot) exercise right privileges
On April 26, 2005, CBOE initiated a purchase offer for a significant number of CBOT exercise right privileges. The exercise 
right privilege is a separately transferable interest representing the exercise right component of a CBOT Full Membership. The 
exercise right refers to the right of all CBOT Full Members to become CBOE members without the need to purchase an Exchange 
membership. In order to utilize the exercise right, the holder of an exercise right privilege must also hold all other rights and 
privileges represented by a CBOT Full Membership (including the interests issued in exchange for CBOT full memberships in the 
corporate restructuring of CBOT implemented effective April 22, 2005). The purchase offer was made in order to give regular 
members of the Exchange a greater interest in and control over CBOE, to limit the number of members able to have access to CBOE, 
and to provide CBOE with more flexibility in managing its affairs. In May and June 2005, a total of 69 exercise right privileges were 
purchased at a price of $100,000 per right. The $6.9 million total purchase price was paid utilizing working capital reserves. This 
amount is reflected net of tax benefits of $2.1 million on the 2005 consolidated statements of income and retained earnings.

In August 2006, one exercise right privilege was purchased at a price of $135,000. This transaction is reflected net of tax benefits 
of $41,000 on the 2006 consolidated statements of income and retained earnings. 

12. subsequent events
The CBOE Stock Exchange, LLC (“CBSX”) was formed as a for-profit entity by five partners, including CBOE. On January 25, 2007, 
the CBSX appointed a Board of Directors and trading operations began on March 5, 2007. CBOE holds four of nine seats on the 
CBSX Board of Directors. CBOE received a 50% share in CBSX in return for non-cash property contributions representing a license 
to use the CBOEdirect trading engine during the term of the company, a license to use the name CBOE Stock Exchange, LLC and 
acronym CBSX in connection with the conduct of CBSX business, and a license to use the business plan and operations manual for 
the conduct of CBSX business, as developed by CBOE, for the term of the company. Other partners invested a total of $25.0 million 
in cash in CBSX. Other partners include Windmill Capital Holdings, LLC, LaBranche & Co., IB Exchange Corp., and SIG Specialists 
Holdings, Inc. 

report of independent registered public accounting firm
To the Board of Directors and Members of Chicago Board Options Exchange, Incorporated 
Chicago, Illinois

We have audited the accompanying consolidated balance sheets of Chicago Board Options Exchange, Incorporated and subsidiaries 
(the “Exchange”) as of December 31, 2006 and 2005, and the related consolidated statements of income and retained earnings 
and of cash flows for the years then ended. These financial statements are the responsibility of the Exchange’s management. Our 
responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing 
audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of 
the Exchange’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, 
on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles 
used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe 
that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Exchange 
as of December 31, 2006 and 2005, and the results of their operations and their cash flows for the years then ended in conformity 
with accounting principles generally accepted in the United States of America.

As discussed in Note 1 to the consolidated financial statements, the Exchange changed its method of accounting for Defined 
Benefit Pension and Other Postretirement Plans in 2006 in order to conform to Statement of Financial Accounting Standards  
No. 158.
