A MessAge froM the office of the chAirMAn
The Chicago Board Options Exchange® (CBOE®) began Fiscal Year (FY) 2006 
aggressively with a major organizational change that will significantly affect all 
aspects of CBOE’s business going forward. On January 1, 2006, the Exchange 
initiated the process of converting from a membership organization to a for-profit 
business model, a move approved by the CBOE Board of Directors in September 
2005. In a rapidly changing business environment, it is our belief that adopting  
a new, more agile business model will give CBOE an important competitive edge 
in meeting the demands of an ever-changing marketplace. In many respects,  
the decision to initiate this landmark transformation was the most important  
development in Fiscal Year 2005.   

CBOE’s conversion to a for-profit model ultimately will impact every area of our 
business, from how we make strategic decisions to how we conduct day-to-day 
operations. It is a change, not only to the organization itself, but also to our orga-
nizational philosophy. The move will enable us to better focus CBOE’s resources 
and to operate more efficiently, while reaffirming the goal of maximizing value for 
owners as well as for customers.  

The initial groundwork has already been laid. Changes to CBOE’s revamped 
corporate model include a streamlined infrastructure and a scaled-down operating 
budget as part of the overall mission to create greater strategic flexibility. As
we venture on, there is still much more work to be done; we are continuing to 
examine all phases of our operation, looking for greater efficiencies and striving 
to create an even better CBOE. 

As we progress with this change to our organization, the Exchange remains 
steadfast in its commitment to continue to develop innovative products, to deliver 
quality service and to enhance our trading technology. Indeed, we believe a 
for-profit model will serve to sharpen our focus on these tenets and improve our 
ability to deliver them.   

We look forward to a bright future where CBOE’s diverse mix of products will 
continue to provide all facets of our customer base with versatile and efficient 
risk management products.

The remainder of this report highlights the significant developments, milestones, 
and achievements at CBOE during Fiscal Year 2005.

record VoluMe And increAsing 
MArket shAre
Fiscal Year 2005 (January 1 to December 31, 2005) 
was arguably the most successful in CBOE’s distin-
guished 32-year history. Trading volume at the  
Exchange soared to all-time record heights and market 
share increased, fortifying CBOE’s bottom line and 
positioning the Exchange financially to initiate the 
important transformation of its business model. 

In a fiercely competitive industry, where market 
share gains and losses are measured by the  
slimmest of margins, CBOE increased its market 
share of total industry volume to 31%. While its 
nearest competitors experienced market share 
declines on the year, CBOE maintained its leadership 
position within the U.S. options industry in 2005.

Trading volume rose to 468.2 million contracts in  
FY 2005 and shattered numerous records. This 
volume total represented the busiest year in CBOE’s 
history for the second consecutive year and was 
a 30% increase over 2004’s record total of 361.1 
million contracts. For the year, average daily volume 
weighed in at nearly 1.9 million contracts.           

Trading in equity options at CBOE totaled 275.6  
million contracts in FY 2005, a rise of 23% over 
2004’s total of 224.3 million, and fell just shy of 
CBOE’s all-time high of 278 million total contracts 
traded in 2000. FY 2005 was the second consecutive 
year that equity options volume posted a gain of at 
least 20%, and since 2002, equity option volume  
has surged 59% at CBOE. 

Trading in options on broad- and sector-based 
indexes and exchange-traded funds (ETFs) experi-
enced explosive growth in FY 2005 with total volume 
reaching 192.5 million contracts, a new record for 
annual index option volume at CBOE, and a jump of 
41% over 2004’s total of 136.7 million contracts. 

Several of CBOE’s index and ETF options logged 
record annual volume in 2005, including options on 
the Nasdaq-100 Index® (NDX®), up 80% over 2004 
to 6.3 million contracts; options on the iShares  
Russell 2000 Index Fund (IWM), up 229% to 16.2 
million; and options on the Russell 2000® Index 
(RUT), up 22% to 1.1 million. 

Options on the S&P 500® Index (SPXSM), CBOE’s 
most actively-traded index product, also experienced 
a record year in 2005 as volume soared to 71.8  
million contracts, surpassing 2004, the previous 
high, by 45%. This record trading in CBOE’s premier 
index product resulted, in part, from the growing 
popularity and increased use of the CBOE S&P 
500 BuyWrite Index (BXMSM) strategy. The BXM is a 
benchmark index that measures the performance of 
a theoretical portfolio that sells covered SPX options 
each third Friday of the month against a portfolio of 
stocks in the S&P 500 Index.     

In addition to the dozens of individual product volume 
records set, the top ten busiest single trading days 
in CBOE history all occurred in 2005, including April 
15, CBOE’s busiest day in 32 years, when over 3.9 
million contracts traded.*

seAt Prices reAch new All-tiMe highs
Rising seat prices during FY 2005 highlighted the 
increasing value of CBOE membership. After the 
first transaction of the year, when a seat sold for 
$299,000 on January 6, 2005, CBOE seat prices  
began a rapid year-long ascent, rising nearly 200%. 
On July 18th, a seat was bought for $755,000, 
eclipsing the three-quarter of a million dollar mark 
for the first time since March 1998. Seat prices 
would continue to set new record levels for the  
remainder of the year, culminating with the year’s  
final seat transaction on December 20th for 
$875,000,** the highest price ever paid for a  
seat at CBOE.

 *CBOE is already setting new volume records in 2006. As of the writing of 
this report, volume at CBOE on Thursday, March 16, 2006 was 5,642,589 
contracts, a new record for the busiest single trading day in the Exchange’s 
33-year history, and the busiest day for any U.S. options exchange. March 
2006 was the busiest month in CBOE history. Its record volume of 55 million 
contracts, an increase of 46% over March 2005, surpassed the previous 
monthly record of 53.9 million contracts from January 2006.

  **CBOE seat prices continue to climb in 2006. A CBOE seat, or membership,  

was bought on February 7, 2006, for the first time ever at a price of 
$1,000,000. On Friday, March 24, 2006, a CBOE seat sold for an all-time  
high of $1,150,000. Twelve CBOE seats were bought for at least one million 
dollars during the first quarter of 2006.

More new Product “firsts” froM cBoe
CBOE, as it has done throughout its history, 
remained at the forefront of new product  
development in FY 2005. In an effort to attract  
business and broaden CBOE’s appeal to an  
expanding universe of customers, several  
innovative investment tools were introduced  
to the marketplace last year.

In total, 293 products were added at CBOE last  
year, including options on 272 individual equities, 
15 cash-settled indexes, and six exchange-traded 
funds. At the end of 2005, the CBOE product line 
included options on 1,766 individual equities, 56 
broad- and sector-based indexes, 61 exchange-
traded funds, four interest rate products and one 
structured product.

State-of-the-art technology combined with the largest pool of 
liquidity providers in the industry make CBOE the world’s most 
dynamic options marketplace.

Other significant new products created and 
launched by CBOE in FY 2005 included Mini-S&P 
500 Index options (XSPSM) which, as a smaller-sized 
version of CBOE’s highly popular S&P 500 Index 
option contract, are especially attractive to retail 
investors; and “WeeklysSM,” short-term options with a 
one-week life from launch to expiration, which provide 
cost-efficient ways to trade around specific news or 
events. Initial Weeklys contracts are based on the 
S&P 500 Index and on the S&P 100® Index, and 
CBOE is currently studying other potential products 
to be offered as Weeklys.

Among the most significant products launched in 
FY 2005 were options on the immensely popular 
SPDRs Exchange-Traded Fund, based on Standard 
& Poor’s® Depositary Receipts (SPY). SPY options 
are now among the most actively-traded products in 
the industry. During FY 2005, CBOE was the leading 
marketplace for SPY options, trading 16.2 million 
contracts and generating a 38% market share from 
a field of primarily screen-based exchanges – a 
testament to CBOE’s large pool of well-capitalized 
market makers and their ability to compete  
effectively with CBOE’s highly-efficient HybridSM 
Trading System.

cBoe exPAnds its PoPulAr Buy-write index coMPlex
The CBOE S&P 500 BuyWrite Index (BXMSM), created by CBOE in 2002, was  
the first benchmark for measuring the performance of covered-call writing. While 
this buy-write strategy is not new, the BXM, for the first time, provided investors 
with a tool to measure the performance of this type of strategy.  

Fueling the interest in the buy-write strategy is a case study done in 2004 on 
BXM by Ibbotson Associates. The study, commissioned by CBOE, found that the 
BXM had the best risk-adjusted performance of the major domestic and interna-
tional equity-based indexes over the 16-year period analyzed. The Ibbotson case 
study has been distributed to tens of thousands of financial advisors and bankers, 
and was a major catalyst in generating awareness of the BXM.

Recognizing growing customer demand for additional quantifiable performance 
measures of the buy-write strategy, in March 2005, CBOE and Dow Jones  
announced the creation of the CBOE DJIA BuyWrite Index (BXDSM), based on  
the Dow Jones Industrial Average; and in September 2005, CBOE and the  
Nasdaq Stock Market®  launched the CBOE NASDAQ-100 BuyWrite Index 
(BXNSM), based on the technology-laden Nasdaq-100 Index.® 

Since the publication of the Ibbotson case study, more than $20 billion has been 
raised for 40 new buy-write funds that use the BXM strategy and at least eight 
major brokerage firms and banks have been granted licenses to offer investment 
products based on one or more of the CBOE buy-write indexes. All three CBOE 
buy-write licenses are now generating licensing revenue for CBOE and its 
index partners.    

cBoe futures exchAnge concludes successful first full yeAr 
Launched on March 26, 2004, the CBOE Futures ExchangeSM (CFESM) is a wholly-
owned subsidiary of CBOE that offers all-electronic trading of futures. At the end 
of CFE’s first full year of trading, volume for 2005 totaled 177,046 contracts, an 
increase of 101% over the 88,194 contracts traded in 2004.

Through the end of 2005, CFE offered futures on 25 products, including the 
CBOE Volatility Index® (VIX®), CBOE DJIA® Volatility Index, CBOE S&P 500  
Three-Month Variance, CBOE China Index, full- and mini-size Russell 1000®  
Indexes, mini-Russell 2000® Index, twelve PowerPacks® sector indexes and, 
most recently, six “Gas At The PumpSM” futures. Gas At The Pump futures, 
launched on October 28, 2005, are designed to track the retail price for regular 
gasoline that consumers pay at the pump throughout different regions of the U.S. 

The launch of futures on the CBOE Volatility Index was a landmark CBOE 
achievement, giving investors, for the first time ever, a viable instrument for  
trading market volatility as an asset class. Until CFE launched VIX futures, the 
CBOE Volatility Index was a benchmark index only – with no way for investors

to trade it. First introduced by CBOE in 1993, VIX 
quickly became the benchmark index of market 
volatility and investor sentiment. Since then, VIX 
has been widely quoted and closely followed and 
is often referred to by industry observers as the 
market’s “fear gauge.” 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. 

To date, futures on the VIX have been CFE’s most 
successful contract, generating 73% of CFE’s  
volume in FY 2005. Not only did trading in VIX  
futures fuel growth at CFE, but it played a role in  
driving volume in CBOE’s SPX options to unprec-
edented heights in 2005, as hedging transactions 
between VIX futures and SPX options is a common 
strategy with volatility traders. 

As a complement to VIX futures, options on VIX  
began trading at CBOE in February 2006. Through 
the first several weeks of trading, average daily 
volume was approximately 10,000 contracts, 
while open interest soared to more than 200,000 
contracts. The marketplace has been quick to 

embrace VIX options, making them not only one of 
the most successful new product launches in CBOE 
history, but one of CBOE’s most recognized products 
as well. With increasing popularity among investors 
and steadily building liquidity, VIX options show even 
greater promise for the future.

OneChicago, the joint venture exchange owned 
by the Chicago Board Options Exchange, Chicago 
Mercantile Exchange Inc. and the Chicago Board 
of Trade, and powered by the CBOEdirect ® trade 
engine, offers all-electronic trading of single stock 
futures and narrow-based indexes. 

At year’s end, OneChicago listed 208 futures on 
single stocks, including futures on DIAMONDS,®  
as well as four OneChicago Select Indexes, a  
series of custom-designed narrow-based security 
index features.  

Trading volume at OneChicago at the close of 2005 
totaled more than 5.5 million contracts traded, an 
increase of 188% over the previous year.

The Hybrid Trading System was 
designed with flexibility in mind 
so that adaptations can be made 
quickly as the dynamics of the 
marketplace change.

cBoe hyBrid: A unique MArket Model
Major progressive changes were made to CBOE’s 
Hybrid Trading System during FY 2005, resulting  
in the expansion of remote trading, additional  
product trading capabilities, greater efficiencies  
and faster access.  

The CBOE Hybrid Trading System combines the best 
features of screen-based trading and floor-based 
markets. The ability afforded by the Hybrid Trading 
System for individual traders to stream live quotes 
and to post quotes with size allows the Exchange to 
better showcase the quality of markets at CBOE. The 
Hybrid offers customers greater liquidity and instan-
taneous point-and-click order execution, while still 
preserving the benefits of trading through open outcry. 
Some customers, especially when trading large or 
complex orders, prefer open outcry, where trades 
can be negotiated in an auction format among a 
deep pool of liquidity providers.

In an increasingly electronic world, the numbers 
validate CBOE’s decision to integrate the open outcry 
component into development of a unique Hybrid 
market model. Ninety-two percent of the orders 
traded on CBOE’s Hybrid Trading System are 

executed electronically, accounting for 55% of the 
volume in those classes, while the remaining 8%  
of Hybrid orders and 45% of the volume are handled 
through the open outcry method of trading. This 
dichotomy illustrates the effective synergies of 
floor- and screen-based trading in CBOE’s Hybrid 
trading world. 

The conversion of all 1,700+ equity classes to 
CBOE’s Hybrid Trading System was completed in 
January, and by the close of 2005, many of the major 
index classes were trading on the Hybrid as well.

Leading the new technological modifications  
added to the Hybrid in 2005 were enhancements  
to facilitate spread order capabilities, which enable  
seamless trading of complex or “multi-legged” 
orders electronically. 

The Hybrid Trading System was designed with 
flexibility in mind so that adaptations can be made 
quickly as the dynamics of the marketplace  
change. As a result, CBOE will be able to continue 
to satisfy the preferences of customers for different 
trading venues.

The competing market maker system coupled with the Hybrid 
trading environment has resulted in CBOE’s quotes being the 
national best market more than 95% of the time.

As part of the evolution of CBOE’s Hybrid Trading System, a new membership 
designation, Remote Market Maker (RMM), was adopted on April 26, 2005. 
The RMM program allows individual market makers or member organizations to 
engage in market making by streaming quotes and trading electronically at CBOE 
from any location, greatly expanding CBOE’s universe of liquidity providers. Over fifty 
firms, including many new to CBOE, are participating in the RMM program. By 
year’s end, RMMs occupied 197 memberships and accounted for nearly 20% of 
daily trading volume in Hybrid classes.

strongly supported by CBOE, has been an important 
issue under consideration by Congress during its 
discussions regarding reauthorization of the futures 
industry regulator, the Commodity Futures Trading 
Commission (CFTC). Reauthorization is scheduled 
every five years as part of the Congressional review 
of the “Commodity Exchange Act.” CBOE’s active 
participation in this process played a significant part 
in having a parity in portfolio margining provision 
included in the legislation, which is currently pending 
on Capitol Hill. In addition, CBOE and the New York 
Stock Exchange have submitted rule filings to the 
Securities and Exchange Commission to expand 
portfolio margining to other products. CBOE’s active 
participation in the legislative process, its ongoing 
efforts to closely monitor legislation affecting our 
customers, and the education of lawmakers regard-
ing the potential impact of legislation on the options 
industry are very important priorities to the Exchange.

reMote trAding site coMPleted
FY 2005 also saw CBOE finish the development 
of its all-electronic, and physically remote disaster 
recovery site. In the event that CBOE’s building and 
trading floor become disabled, this back-up trading  
facility will provide CBOE with the capability to  
resume trading electronically on a next-day basis.  
Testing between the Exchange and member firms 
was completed in the fourth quarter of 2005 and the 
site became operational early in 2006. In the first 
phase of implementation, CBOE’s exclusively listed 
index products have been readied, while subsequent 
phases will prepare additional products for trading 
via the site.

cBoe links with chinA’s MArkets
In an effort to expand CBOE’s reach globally, the 
Exchange was pleased to enter into Memoranda of 
Understanding (MOUs) with five Chinese stock and 
derivatives exchanges – the Shanghai and Shen-
zhen Stock Exchanges, the Dalian and Zhengzhou 
Commodity Exchanges and the Shanghai Futures 
Exchange – during FY 2005. These links with 
China’s emerging markets will lay the foundation for 
collaborative efforts between the CBOE and Chinese 
marketplaces, facilitate the development of channels 
of communication, and foster continuing relationships 
between the exchanges for the respective benefits  
of the financial services industry in the U.S. and  
the People’s Republic of China. In the months and 
years to come, the MOUs will enable CBOE and our 
Asian counterparts to work jointly to share ideas,  
exchange resources and explore potential new  
product development.

Portfolio MArgining AdVocAted
Throughout 2005, CBOE worked closely with the 
U.S. Securities Market Coalition, which represents 
the six U.S. options exchanges, to advocate for parity 
in portfolio margining for stock options and single 
stock futures. Parity in portfolio margining, which is

A Vision for the future
Fiscal Year 2006 will be a pivotal year for CBOE. Through the challenges and 
change that await in the new year, so too, does opportunity. As competition 
continues to intensify, not only among existing options exchanges, but from the 
looming threat of new market entrants, CBOE is poised to remain the industry 
leader. CBOE’s Hybrid Trading System has proven to be a robust and highly- 
efficient market model, carving a unique niche into a crowded marketplace, and 
moving forward, the Exchange will keep refining the system. With the conversion 
to a new for-profit business model, and the strategic optionality it provides, CBOE 
will have the agility to pursue new initiatives, while maintaining the flexibility to 
meet whatever challenges the future may hold. One thing that will not change, 
however, is CBOE’s mission to continue bringing innovative investment products, 
cutting-edge technology and unparalleled customer service to the world’s most 
dynamic options marketplace.   

Through the challenges and  
change that await in the new

005 finAnciAl suMMAry
The year 2005 represents the first calendar year financial reporting period for  
the Exchange. Prior to 2005, the Exchange reported on a June 30 fiscal year-end 
basis. The process of changing our fiscal year-end included the transition step of 
reporting results for a six month period ended December 31, 2004 (prior period). 
These results are presented for comparative purposes. 

The Exchange experienced a successful financial year in 2005 due to record 
trading volume of 1.85 million contracts per day. In the prior period, the Exchange 
averaged 1.4 million contracts per day. The Exchange earned net income of $10.9 
million versus $1.2 million in the prior period. 

The significant growth (32%) in 2005 trading volume versus the prior period was 
the main reason current year revenues were $25.2 million (14%) higher than 
the prior period on an annualized basis. Fee reductions and fee caps saved our 
customers and members $31.6 million in 2005 versus $12.0 million in the prior 
period annualized.

Expenses were $10.2 million higher than the prior period annualized, mainly due 
to employee costs ($8.4 million) and royalty fees ($4.0 million). Employee costs 
were higher in 2005 mainly due to year-end bonus awards and merit increases. 
Bonus awards were not paid in the six month period ended December 31, 2004. 
Royalty fees increased in 2005 due to significant trading volume growth in 
certain licensed products.

Capital spending in 2005 amounted to approximately $21.0 million. Investments 
were primarily in the Systems Division related to the Hybrid Trading System and 
other trading floor enhancements. In addition, the Exchange contributed $0.8  
million in capital to OneChicago, LLC in 2005.  

In 2005 the Exchange sold 69 (45%) of our National Stock Exchange (NSX)  
certificates of proprietary membership to NSX for $5.0 million. See financial  
statements Note 2 for details of the Termination of Rights Agreement with NSX. 

The Exchange purchased 69 Chicago Board of Trade exercise right privileges in 
2005 for a total amount of $6.9 million. See financial statements Note 9 for details 
of the purchase of Chicago Board of Trade exercise right privileges.

Retained earnings increased to $120.0 million and total members’ equity at  
December 31, 2005 was $140.9 million. At year’s end, the Exchange was  
debt-free with working capital of $59.9 million.

Chicago Board Options Exchange, Incorporated and Subsidiaries 
For the year ended December 31, 2005 and the six month period ended December 31, 2004

.  suMMAry  of  significAnt  Accounting  Policies
nature of Business – The Chicago Board Options Exchange, Incorporated and Subsidiaries (“the Exchange”) is a registered securities 
exchange, subject to oversight by the Securities and Exchange Commission. The Exchange’s principal business is providing a marketplace 
for trading equity and index options. 

Basis of Presentation – During 2004 the Exchange changed its year-end from June 30 to December 31. Accordingly, the accompanying 
financial statements reflect the calendar year ended December 31, 2005 and the six month period ended December 31, 2004. The consoli-
dated financial statements include the accounts and results of operations of 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 cost which approximates their fair market value 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 the Exchange’s share of distributable revenue receivable from OPRA. 

investments in Affiliates – Investments in affiliates represent investments in OCC, OneChicago, LLC (“ONE”) and The National Stock 
Exchange (“NSX”). The investment in OCC (20% of its outstanding stock) is carried at cost because of the Exchange’s inability to exercise 
significant influence. The Exchange accounts for the investments in NSX (55% of its total certificates of proprietary membership) and ONE 
(approximately 40% of its outstanding stock) under the equity method due to the lack of effective control over the operating and financing 
activities of each affiliate. 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 an impairment, the Exchange 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. 

data Processing software & software development work in Progress – Data processing software and software development work in  
progress 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 the Exchange for which services have not been provided.   

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.

The Exchange and NSX executed a Termination of Rights Agreement (TORA) on September 27, 2004. Pursuant to the TORA, NSX will  
purchase 153 (94%) of the NSX certificates of proprietary membership currently owned by the Exchange. Certificates of proprietary  
membership will be surrendered by CBOE and NSX will pay the Exchange 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. The present 
value of the sale price is $10.7 million. The Exchange will ultimately retain nine certificates of proprietary membership (10% of the total  
outstanding certificates of proprietary membership). After the sale of 153 certificates, the Exchange 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. The Exchange’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, the Exchange exercised its first put right under the TORA. On this date,  
the Exchange surrendered an additional 21 certificates of proprietary membership and NSX paid CBOE $1.5 million. The Exchange’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.

The Exchange, the Chicago Mercantile Exchange Holdings, Inc. and the Board of Trade of the City of Chicago, Inc. are partners in ONE,  
a joint venture created to trade single stock futures. Certain ONE employees also have minority interests in the joint venture. ONE is a  
for-profit entity with its own management and board of directors, and is separately organized as a regulated exchange. The Exchange  
contributed $0.8 million in capital to ONE during 2005. The Exchange had a receivable due from ONE of $0.9 million at December 31, 
2005. At December 31, 2005, the Exchange’s investment in ONE was $0.1 million after deducting our equity in ONE operating losses.

impairment charge for nsx – As is necessary under APB 18, which requires an adjustment to the carrying value of an asset when there  
is a decline (other than temporary) in the value of an asset that causes its current fair market value to be less than the carrying amount,  
the Exchange determined in the year ended December 31, 2005 that the value of its equity investment in NSX was impaired by $2.4  
million and consequently lowered the value of its investment to reflect the estimated fair market value of its ownership interest in NSX. The 
fair market value of the investment was based on the sale price for 153 (94% of its current investment) of the NSX certificates of proprietary 
membership it currently owns (see note 6). Management believes this sale price is a basis for approximating the fair value of its  
investment in NSX.

impairment charge for investment in derivatech, inc. – The Exchange executed a stock purchase agreement with Derivatech, Inc. on 
February 12, 1997 for the purpose of acquiring The Options Toolbox software education code. Since that time, the investment was  
carried at the cost of $315 thousand on the Exchange’s balance sheet. An impairment review concluded it was prudent to recognize the  
full impairment of the asset in 2005.

.  relAted  PArties
The Exchange collected transaction and other fees of $191.2 million by drawing on accounts of the Exchange’s members held at OCC. 
The amount collected during 2005 included $42.1 million of marketing fees (see note 8). The Exchange had a receivable due from OCC of 
$15.2 million at December 31, 2005.

The Exchange incurred rebillable expenses on behalf of NSX, for expenses such as employee costs, computer equipment and office space 
of $3.8 million during 2005. The Exchange had a receivable from NSX of $931 thousand at December 31, 2005.

OPRA is a committee administered jointly by the six options exchanges and is authorized by the Securities and Exchange Commission 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 distrib-
uted to the Exchange was $16.7 million during 2005. The Exchange had a receivable from OPRA of $4.4 million at December 31, 2005.

The Exchange incurred administrative expenses of $3,600 for its affiliate, the Chicago Board Options Exchange Political Action Committee 
(the “Committee”), during 2005. 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 the Exchange, and to contribute funds to the election campaigns of candidates for federal offices. 

.  leAses
The Exchange leases office space with lease terms remaining from seventeen months to twenty-five months as of December 31, 2005.  
Rent expenses related to leases for the year ended December 31, 2005 were $802 thousand. Future minimum lease payments under these 
noncancellable operating leases are as follows at December 31, 2005 (in thousands):

5.  eMPloyee  Benefits
Eligible employees participate in the Chicago Board Options Exchange SMART Plan (the “SMART Plan”). The SMART Plan is a defined  
contribution plan, which is qualified under Internal Revenue Code Section 401(k). The Exchange contributed $4.3 million to the SMART 
Plan for the year ended December 31, 2005.

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

The Exchange 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 the 
Exchange. Contributions to the trust are based on reserve levels established by Section 419(a) of the Internal Revenue Code. During the 
year ended December 31, 2005, the Exchange contributed $5.6 million to the trust. 

.  coMMitMents  And  contingencies
In September 2000, the Exchange reached an agreement in principle to settle a consolidated civil class action lawsuit filed against the 
Exchange and other U.S. options exchanges and certain market maker firms. The Exchange 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 Exchange and other settling parties reached a revised settlement that resolved certain disputes concerning the 
interpretation of certain provisions of the original settlement agreement. On February 8, 2006, the U.S. District Court preliminarily approved 
the revised settlement. Final approval is pending. As a result of the revised settlement, CBOE’s settlement amount was reduced to $9.3  
million. On February 22, 2006 CBOE received a refund of $7.1 million, including accrued interest. If final approval is denied, the settling 
parties will revert to their positions regarding the original settlement.

The Exchange is currently a party to various legal proceedings. Litigation is subject to many uncertainties, and the outcome of individual 
litigated matters is not predictable with assurance. After discussions with counsel, it is the opinion of management that the outcome of such 
matters will not have a material adverse impact on the consolidated financial position, results of operations or cash flows in the Exchange. 

.  incoMe  tAxes 
A reconciliation of the statutory federal income tax rate to the effective income tax rate, for the year ended December 31, 2005 is as follows: 

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

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

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 Exchange 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 the Exchange, to limit the number of members able to have access to the Exchange, and to provide the Exchange 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 consolidated statements of income and retained earnings.

0.  deferred  reVenue
Effective October 1, 2004, the Exchange instituted a fixed transaction fee program. Under the plan, Designated Primary Market Makers 
(DPMs) and electronic DPMs (e-DPMs) may 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 
unearned income. This amount was amortized and recorded as transaction revenues monthly during 2005. Prepayments for the 2006 fixed 
fee program were received in 2006.

In December 2005, the Exchange collected $7.9 million representing annual regulatory fees amortized over the twelve-month period of  
July 2005 through June 2006. The amount included in unearned income as of December 31, 2005 totaled $3.9 million.

.  suBsequent  eVents
On February 3, 2006, ONE issued a capital call to the owners of ONE for a total amount of $2.7 million. On February 10, 2006, the 
Exchange paid $1.1 million to ONE, representing the Exchange’s share of the capital call. 

On March 15, 2006, Interactive Brokers Group LLC (IB) made a significant equity investment in ONE. IB is an electronic broker-dealer. 

On February 22, 2006 the Exchange and HedgeStreet Inc. announced a strategic alliance for the joint development of new products,  
sharing of technology services, and marketing and support of HedgeStreet’s products. Launched in 2004, HedgeStreet is a CFTC  
regulated exchange, a designated contract market, and a registered derivatives clearing organization. CBOE also made an equity  
investment in HedgeStreet.

To the Board of Directors and Members of the Chicago Board Options Exchange, Incorporated and Subsidiaries:

We have audited the accompanying consolidated balance sheets of the Chicago Board Options Exchange, Incorporated and subsidiaries 
(the “Exchange”) as of December 31, 2005 and 2004, and the related consolidated statements of income and retained earnings and of 
cash flows for the year ended December 31, 2005 and for the six months ended December 31, 2004. 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 auditing standards generally accepted in the United States of America. 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 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 manage-
ment, as well as evaluating the overall financial statement presentation. We believe that our audit provides 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 and its 
subsidiaries as of December 31, 2005 and 2004, and the results of its operations and its cash flows for the year ended December 31, 2005 
and for the six months ended December 31, 2004, in conformity with accounting principles generally accepted in the United States  
of America.
