Forward-Looking Statements

This report contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by words such as “expects,” “intends,” “anticipates,” “plans,” “believes,” “seeks,” “estimates,” “will,” or words of similar meaning and include, but are not limited to, statements regarding the outlook for our future business and financial performance. Forward-looking statements are based on management’s current expectations and assumptions, which are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. It is routine for our internal projections and expectations to change as the year or each quarter in the year progresses, and therefore it should be clearly understood that the internal projections and beliefs upon which we base our expectations may change prior to the end of each quarter or the year. Although these expectations may change, we are under no obligation to revise or update any forward-looking statements contained in this report. Our company policy is generally to provide our expectations only once per quarter, and not to update that information until the next quarter. Actual future events or results may differ materially from those contained in the projections or forward-looking statements. Factors that could cause or contribute to such differences include those discussed below and elsewhere in this report, particularly in Item 1A., “Risk Factors.”


Item 1.	*Business*

MarketAxess operates one of the leading platforms for the electronic trading of corporate bonds and certain other types of fixed-income securities. Through our platform, 689 active institutional investor client firms (firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006) can access the aggregate liquidity provided by the collective interest of our 25 broker-dealer clients in buying or selling bonds through our platform. Our active institutional investor clients include investment advisers, mutual funds, insurance companies, public and private pension funds, bank portfolios and hedge funds. We also provide data and analytical tools that help our clients make trading decisions and we facilitate the trading process by electronically communicating order information between trading counterparties. Our revenues are primarily generated from the trading of U.S. and European high-grade corporate bonds.

Our multi-dealer trading platform allows our institutional investor clients to simultaneously request competing, executable bids or offers from our broker-dealer clients and execute trades with the broker-dealer of their choice from among those that choose to respond. We offer our broker-dealer clients a solution that enables them to efficiently reach our institutional investor clients for the distribution and trading of bonds. In addition to U.S. high-grade corporate bonds, European high-grade corporate bonds and emerging markets bonds, including both investment-grade and non-investment grade debt, we also offer our clients the ability to trade crossover and high-yield bonds, agency bonds and credit default swaps. Our DealerAxess^® trading service allows dealers to trade fixed-income securities with each other on our platform.

The majority of our revenues are derived from commissions for trades executed on our platform that are billed to our broker-dealer clients on a monthly basis. We also derive revenues from information and user access fees, license fees, investment income and other income. Our expenses consist of employee compensation and benefits, depreciation and amortization, technology and communication expenses, professional and consulting fees, marketing and advertising and other general and administrative expenses.

Traditionally, bond trading has been a manual process, with product and price discovery conducted over the telephone between two or more parties. This traditional process has a number of shortcomings resulting primarily from the lack of a central trading facility for these securities, which creates difficulty matching buyers and sellers for particular issues. In recent years, an increasing number of corporate bond trading participants have utilizede-mail and other electronic means of communication for trading corporate bonds. While this has addressed some of the shortcomings associated with traditional corporate bond trading, we believe that the process is still hindered by limited liquidity, limited price transparency, significant transaction costs, compliance and regulatory challenges, and difficulty in executing numerous trades at one time.

Through our electronic platform, our institutional investor clients can determine prices available for a security, a process called price discovery, as well as trade securities directly with our broker-dealer clients. The price discovery process includes the ability to view indicative prices from the broker-dealer clients’ inventory available on our platform, access to real-time pricing information and analytical tools (includingspread-to-Treasury data, search capabilities and independent credit research) available on our Corporate BondTicker^TM service and the ability to request executable bids and offers simultaneously from up to 19 of our broker-dealer clients during the trade process. On average, institutional investor clients receive several bids or offers from broker-dealer clients in response to trade inquiries. However, some trade inquiries may not receive any bids or offers. Our services relating to trade execution include single and multiple-dealer inquiries; list trading, which is the ability to request bids and offers on multiple bonds at the same time; and swap trading, which is the ability to request an offer to purchase one bond and a bid to sell another bond, in a manner such that the two trades will be executed simultaneously, with payment based on the price differential of the bonds. Once a trade is completed on our platform, the broker-dealer client and institutional investor client may settle the trade with the assistance of our automated post-trade messaging, which facilitates the communication of trade acknowledgment and allocation information between our institutional investor and broker-dealer clients. We are not a party to the actual trades that occur on our platform between institutional investor clients and broker-dealer clients; rather, we serve as an intermediary between broker-dealers and institutional investors, enabling them to meet, agree on a price and then transact with each other.

In June 2006, we introduced our DealerAxess^® service, which allows our broker-dealer clients to transact U.S. corporate and emerging markets bond trades on our platform with other broker-dealer clients. Our broker-dealer clients can execute these trades in a more efficient manner and at lower transaction costs than in the traditional voice-brokered inter-dealer market. Although DealerAxess^® is a completely segregated trading platform, it shares the same core technology as ourclient-to-dealer platform. MarketAxess Corporation, our U.S. subsidiary, acts as intermediary in these transactions between broker-dealer clients by serving as counterparty to the two broker-dealer clients involved.

Our client base includes 25 of the leading broker-dealers in global fixed-income trading and 689 active institutional investor firms (firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006). Our broker-dealer clients accounted for approximately 96% of the underwriting of newly-issued U.S. high-grade corporate bonds and approximately 75% of the underwriting of newly issued European high-grade corporate bonds in 2006. We believe these broker-dealers also represent the principal source of secondary market liquidity in the other markets in which we operate. Secondary market liquidity refers to the ability of market participants to buy or sell a security quickly and in large volume subsequent to the original issuance of the security, without substantially affecting the price of the security. Our broker-dealer clients currently trade fixed-income securities by traditional means including telephone,e-mail and proprietary single-dealer systems in addition to our electronic trading platform and we expect them to continue to do so in the future. We believe that these traditional means of trading remain the manner in which the majority of bonds are traded between institutional investors and broker-dealers. Our volume in U.S. high-grade corporate bonds represented 8.5% of the total U.S. high-grade corporate bond volume, excluding convertible bonds, for 2006 as reported by the National Association of Securities Dealers, Inc. (“NASD”) Trade Reporting and Compliance Engine (“TRACE”), which includes inter-dealer and retail trading as well as trading between institutional investors and broker-dealers. We have not identified a reliable source of data relating to either the total volume ofclient-to-dealer trading or the size of the other markets we serve and therefore are unable to accurately determine the total volume of secondary trading of these bonds or the portion of such trading conducted on our platform.

Results for Calendar Years 2006, 2005 and 2004

Our trading volume, commissions and total revenues remained relatively constant from 2004 to 2005. From 2005 to 2006, our trading volume increased by 13.5%, commissions increased by 6.7% and total revenues increased by 6.1%. Income before taxes declined in both 2005 and 2006 compared to the prior years as a result of higher expenses. Expenses increased between 2005 and 2006 by $7.7 million or 11.5%. Incremental stock compensation expense as a result of the implementation of Statement of Financial Accounting Standards No. 123 (revised 2004) “Share-Based Payment” (“SFAS 123R”), in January of 2006 accounted for $3.2 million of this expense increase. Our summary results for the years ended December 31, 2006, 2005 and 2004 are provided in the following table:


	Year Ended December 31,
	2006		2005		2004

Total trading volume (in billions)	$	339.6	$	299.2	$	298.1
Total commissions (in millions)		71.4		66.9		68.2
Total revenues (in millions)		83.3		78.6		75.8
Income before taxes (in millions)		8.6		11.6		17.3

For the year ended December 31, 2006, 57.5% of our total volume was in U.S. high-grade corporate bonds, 25.8% was in European high-grade corporate bonds and 16.7% was in Other, most of which was emerging markets and agency bonds.

Industry Background

Fixed-income securities are issued by corporations, governments and other entities, and pay a pre-set absolute or relative rate of return. As of December 31, 2006, there were approximately $26.7 trillion of fixed-income securities outstanding in the U.S. market, including $5.4 trillion of U.S. corporate bonds. We are primarily active in six segments of the global fixed-income securities market: U.S. high-grade corporate bonds; European high-grade corporate bonds; emerging markets bonds; crossover and high-yield bonds; agency bonds; and credit default swaps.

U.S. High-Grade Corporate Bond Market

The total amount of U.S. corporate bonds outstanding has grown from $3.0 trillion as of December 31, 1999 to $5.4 trillion as of December 31, 2006. The average daily trading volume of U.S. corporate bonds increased from approximately $17.9 billion in 2002 (the first calendar year for which such data are available) to $22.7 billion in 2006.

The U.S. corporate bond market consists of three broad categories of securities: investment-grade debt (so-called “high-grade”), which typically refers to debt rated BBB− or better by Standard & Poor’s or Baa3 or better by Moody’s Investor Service; debt rated below investment-grade (so-called “high-yield”), which typically refers to debt rated lower than BBB− by Standard & Poor’s or Baa3 by Moody’s Investor Service; and debt convertible into equity (so-called “convertible debt”).

The U.S. high-grade corporate bond market, which represents the largest subset of the U.S. corporate bond market, has undergone significant change over the last several years, which has been driven by a number of factors, including:


	•	Improved price transparency — In 2002, the NASD adopted TRACE reporting, which requires NASD members to report secondary market transactions in certain fixed-income securities to the NASD. Since February 2005, the list of TRACE-eligible bonds has included 23,000 unique securities, representing 99% of the daily trading volume of high-grade bonds.

	•	Introduction of electronic trading platforms — Electronic trading platforms, which are in the early stages of adoption, act as central facilities to bring together buyers and sellers. The actions of participants on these platforms are facilitated by an electronic medium that improves some of the manual processes that might otherwise be required, such as searching for securities with specific characteristics, the coordination of multiple bilateral telephone calls or electronic communications, the sorting and analysis of competing bids


		or offers, and the entry of orders into the trading system after verbal ore-mail trade agreement. As a result, these platforms typically provide a lower-cost and more efficient means of enhanced distribution and trade execution than previously possible.


	•	Introduction of credit derivatives — Credit derivatives provide increased flexibility and liquidity for investors and lenders to diversify their credit exposures. The appeal of these products is apparent in the growth in the total notional amount of outstanding credit default swaps. According to the International Swaps and Derivatives Association, Inc. (‘ISDA’), the total notional amount of credit default swaps outstanding grew from approximately $900 billion at December 31, 2001 to approximately $26 trillion at June 30, 2006.

	•	Growth in the total amount of debt outstanding — The total size of the U.S. high-grade corporate bond market has increased significantly since 1998, when approximately $564 billion gross amount of new bonds were issued. By 2006, the amount of gross corporate issuance had grown to $1,059.9 billion, as illustrated in the chart below:

European High-Grade Corporate Bond Market

The European high-grade corporate bond market consists of a broad range of products, issuers and currencies. We define the European high-grade corporate bond market generally to consist of bonds intended to be distributed to European investors, primarily bonds issued by European corporations, excluding bonds that are issued by a corporation domiciled in an emerging markets country and excluding most government bonds that trade in Europe.

We believe that the European high-grade corporate bond market is impacted by many of the same factors as the U.S. high-grade corporate bond market. In addition, we believe the following factors are unique to the European high-grade corporate bond market:


	•	Adoption of the Euro — The adoption of the Euro as the common currency in most European Union countries has reduced the importance of currency as an investment selection criterion and elevated the importance of the credit risk of particular issuers. As a result, institutional investors have exhibited a greater interest in investing in a broader range of bonds issued by entities domiciled outside of their home countries.

	•	Regulatory environment — Certain European Union countries have eased restrictions that required institutional investors to invest primarily in domestic securities. This has provided European institutional investors with increased flexibility to invest in securities issued by entities domiciled in other countries within the European Union. On November 1, 2007, the Markets in Financial Instruments Directive


		(“MiFID”) comes into effect. MiFID is designed to further harmonize the financial markets of the member states of the European Union and introduces new pre- and post-trade transparency requirements.


	•	Common liquidity pool — The larger capital pool created by the common currency and changes in the regulatory environment have enabled European corporations to offer larger issues, which has resulted in increases in the liquidity and trading volumes of these issues. This has attracted even more institutional investors, who prefer to invest in highly-liquid markets.

Emerging Markets Bond Market

We define the emerging markets bond market generally to include U.S. dollar- or Euro-denominated bonds issued by sovereign entities or corporations domiciled in a developing country. These issuers are typically located in Latin America, Asia, or Central and Eastern Europe. Examples of countries we classify as emerging markets include: Brazil, Colombia, Mexico, Peru, the Philippines, Russia, Turkey and Venezuela.

The institutional investor base for emerging markets bonds has recently expanded to include many crossover investors from the high-yield and high-grade investment areas. Institutional investors have been drawn to emerging markets bonds by their high returns and high growth potential, as well as by a general trend toward positive economic and political reforms and improving economic performance in many emerging markets countries.

Crossover and High-Yield Bond Market

We define the high-yield bond market generally to include all debt rated lower than BBB- by Standard & Poor’s or Baa3 by Moody’s Investor Service. We define the crossover market to include any debt issue rated below investment grade by one agency but investment grade by the other. The total amount of high-yield corporate bonds yearly issuance has grown from $130.9 billion for the year ending December 31, 2003 to approximately $149.1 billion for the year ending December 31, 2006.

The NASD began publicly disseminating real-time price information on approximately 12,000 high-yield corporate bond issues in 2005. Trades in bonds rated BB and lower are subject to immediate dissemination if the trade size is less than $1 million, or greater than $1 million and trades an average of once or more a day. The disseminated set was expanded on February 1, 2005 to include reporting of certain transactions on a delayed basis. The average daily trading volume of high-yield bonds reported by the NASD for the year ended December 31, 2006 was $4.8 billion.

Agency Bond Market

We define the agency bond market to include debt issued by a U.S. government-sponsored agency. The offerings of these agencies are backed by, but not guaranteed by, the U.S. government. Some prominent issuers of agency bonds are the Student Loan Marketing Association (“Sallie Mae”), Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”). The total amount of U.S. agency bonds outstanding has grown from $1.9 trillion as of December 31, 2000 to $2.7 trillion as of December 31, 2006.

The Federal Reserve Bank of New York reported average daily trading volume in federal agency and government sponsored enterprise securities (excluding mortgage-backed securities) for 2006 of $15.6 billion.

Credit Default Swap Market

Credit default swaps (“CDS”) are contracts that transfer an asset’s risk and return from one party to another without transferring ownership of the underlying asset, allowing market participants to obtain credit protection or assume credit exposure associated with a broad range of issuers of fixed-income securities and other debt obligations. They are often designed to hedge other exposures and can be tied to particular events, such as a default, bankruptcy or ratings downgrade. CDS provide increased flexibility and liquidity for investors and lenders to diversify their credit risk. Approximately half of the volume traded in CDS is index products, which give exposure to a defined basket of underlying credit default swaps. The remainder is traded in single-name CDS. The appeal of these products is apparent in the growth in the total notional amount of outstanding CDS, as illustrated in the chart below:

Our Competitive Strengths

Our electronic trading platform provides solutions to some of the shortcomings of traditional bond trading methods. The benefits of our solution are demonstrable throughout the trading cycle:


	•	Pre-trade — gathering real-time and historical pricing information, identifying interested buyers and sellers in a particular security, and obtaining research and analysis;

	•	Trade — single and multiple security trade execution; and

	•	Post-trade — trade detail matching, account allocation and automated audit trail.

We believe that we are well positioned to strengthen our market position in electronic trading in our existing products and to extend our presence into new products and services by capitalizing on our competitive strengths, including:

Significant Trading Volumes with Participation by Leading Broker-Dealers and Institutional Investors

Our electronic trading platform provides access to the liquidity provided through the participation on our platform of 25 of the leading global securities broker-dealers and 689 active institutional investor firms (firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006). We believe these broker-dealers represent the principal source of secondary market liquidity for U.S. high-grade corporate bonds, European high-grade corporate bonds, emerging markets bonds and the other markets in which we operate. Our broker-dealer clients are motivated to continue to utilize our platform due to the presence on the

platform of our large network of institutional investor clients. We believe that if we continue to grow the participation of our broker-dealer and institutional investor clients on our electronic trading platform, the benefits in liquidity on the platform to both broker-dealers and institutional investors will be amplified, further motivating them to use our platform. The growth of our active institutional investor clients for the past five years has been as follows:

Our total trading volume has grown over the past five years as indicated below:

Our volume in U.S. high-grade corporate bonds grew from 6.4% of total U.S. high-grade corporate bond volume, excluding convertible bonds, in 2004 as reported by NASD TRACE, which includes inter-dealer and retail trading as well as trading between institutional investors and broker-dealers, to 8.5% in 2006, as shown in the chart below:

We have not identified a reliable source of data relating to either the total volume ofclient-to-dealer trading or the size of the other markets we serve and therefore we are unable to accurately determine the total volume of secondary trading of these bonds or the portion of such trading conducted on our platform.

Execution Benefits to Clients

Benefits to Institutional Investor Clients

We believe we provide numerous benefits to our institutional investor clients over traditional fixed-income trading methods, including:

Competitive Prices. By enabling institutional investors to simultaneously request bids or offers from our broker-dealer clients, we believe our electronic trading platform creates an environment that motivates our broker-dealer clients to provide competitive prices and gives institutional investors confidence that they are obtaining a competitive price. For typical MarketAxess multi-dealer corporate bond inquiries, the range of competitivespread-to-Treasury responses is, on average, approximately 10 basis points (a basis point is 1/100 of 1% in yield). As an example of the potential cost savings to institutional investors, a one basis point savings on a $1 million face amount trade of a bond with 10 years to maturity translates to aggregate savings of approximately $750.00.

Transparent Pricing on a Range of Securities. The commingled multi-dealer inventory of bonds posted by our broker-dealer clients on our platform consists of a daily average of more than $136 billion in indicative bids and offers. Subject to applicable regulatory requirements, institutional investors can search bonds in inventory based on any combination of issuer, issue, rating, maturity,spread-to-Treasury, size and dealer providing the listing, in a fraction of the time it takes to do so manually. Institutional investor clients can also request executable bids and offers on our electronic trading platform on any debt security in a database of U.S. and European corporate bonds, although there can be no assurance as to the number of broker-dealers who will choose to provide an executable price. Our platform transmits bid and offer requests in real-time to broker-dealer clients, who may respond with executable prices within a time period specified by the investor.

Improved Cost Efficiency. We believe that we provide improved efficiency by reducing the time and labor required to conduct broad product and price discovery. Single-security and multi-security (bid or offer lists)

inquiries can be efficiently conducted with multiple broker-dealers. In addition, our Corporate BondTicker eliminates the need for manually-intensive phone calls ore-mail communication to gather, sort and analyze information concerning historical transaction prices.

Benefits to Broker-Dealer Clients

We also provide substantial benefits to our broker-dealer clients over traditional fixed-income trading methods, including:

Greater Sales Efficiency. We offer our broker-dealer clients broad connectivity with their institutional investor clients. Through this connectivity, our broker-dealer clients are able to efficiently display their indications of interest to buy and sell various securities. We also enable broker-dealers to broaden their distribution by participating in transactions to which they otherwise may not have had access. In addition, the ability to post prices and electronically execute on straightforward trades enables bond sales professionals at broker-dealer firms to focus their efforts on more profitable activities, such as higher value-added trades and more complex transactions.

More Efficient Inventory Management for Broker-Dealers. The posting of inventory to, and the ability to respond to inquiries from, a broad pool of institutional investors, creates an increased opportunity for broker-dealers to identify demand for their inventory, particularly in less liquid securities. As a result, we believe they can achieve enhanced bond inventory turnover, which may limit credit exposure.

Benefits to Both Institutional Investor and Broker-Dealer Clients

We offer additional benefits over traditional fixed-income trading methods that are shared by both institutional investor and broker-dealer clients, including:

Greater Trading Accuracy. Our electronic trading platform includes verification mechanisms at various stages of the execution process which result in greater accuracy in the processing, confirming and clearing of trades between institutional investor and broker-dealer clients. These verification mechanisms are designed to ensure that our broker-dealer and institutional investor clients are sending accurate trade messages by providing multiple opportunities to verify they are trading the correct bond, at theagreed-upon price and size. Our platform assists our institutional investor clients in automating the transmittal of order tickets from the portfolio manager to the trader, and from the trader to back-office personnel. This automation provides more timely execution and a reduction in the likelihood of errors that can result from information being manually entered into different systems.

Efficient Risk Monitoring and Compliance. Institutional investors and their regulators are increasingly focused on ensuring that best execution is achieved for fixed income trades. Our electronic trading platform offers both institutional investors and broker-dealers an automated audit trail for each stage in the trading cycle. This enables compliance personnel to review information relating to trades more easily and with greater reliability. Trade information including time, price andspread-to-Treasury is stored securely and automatically on our electronic trading platform. These data also represent a valuable source of information for our clients’ compliance personnel. Importantly, we believe the automated audit trail, together with the competitive pricing that is a feature of our electronic trading platform, gives fiduciaries the ability to demonstrate that they have achieved best execution on behalf of their clients.

Other Service Offerings

In addition to services directly related to the execution of trades, we offer our clients several other services, including:

Information Services. The information and analytical tools we provide to our clients help them make investment and trading decisions. Our Corporate BondTicker provides access to real-time and historical price, yield and MarketAxess estimatedspread-to-Treasuries for publicly disseminated NASD TRACE-eligible bonds. Corporate BondTicker combines publicly-available TRACE data with the prices for trades executed on our U.S. high-grade electronic trading platform, integrating the two data sources and providing real-time TRACE data with associated analytical tools that are not otherwise available. In addition, Corporate BondTicker provides indicative prices for secondary loans and credit default swaps, through arrangements with certain of our broker-dealer clients,

and independent credit research. Our electronic trading platform allows institutional investors to compile, sort and use information to discover investment opportunities that might have been difficult or impossible to identify using a manual information gathering process or other electronic services.

In November 2006, we added a comprehensive set of reports designed to review and monitor credit trading activity for institutional investor clients. It utilizes extensive TRACE information and has a flexible interface to run and save reports in a variety of formats for both compliance and management reporting. For example, the best execution report provides a view of the savings generated by trading on our electronic trading platform and offers a quantitative measure of the value of price discovery from multiple dealers. The report allows clients to monitor performance against their own best execution policy. Our compliance product provides a printed history of each inquiry submitted through the MarketAxess trading platform.

Straight-Through Processing. Straight-through processing (“STP”) refers to the integration of systems and processes to automate the trade process fromend-to-end — trade execution, confirmation and settlement — without the need for manual intervention. Our electronic trading platform provides broker-dealers and institutional investors with the ability to automate portions of their transaction processing requirements, improving accuracy and efficiency. Through electronic messaging, institutional investors can submit inquiries to, and receive electronic notices of execution from us, in industry standard protocols, complete with all relevant trade details. Institutional investors can download trade messages, allocate trades tosub-accounts on whose behalf the trades were made and send the allocations to broker-dealers for confirmation.

Robust, Scalable Technology Platform

We have developed proprietary technology that is highly secure, fault-tolerant and provides adequate capacity for our current operations, as well as for substantial growth. Our highly scalable systems are designed to accommodate additional volume, products and clients with relatively little modification and low incremental costs.

Proven Innovator with an Experienced Management Team

Since our inception, we have been an innovator in the fixed-income securities markets. Our management team is comprised of executives with an average of more than 20 years’ experience in the securities industry. We have consistently sought to benefit participants in the markets we serve by attempting to replicate the essential features of fixed-income trading, including the existing relationships between broker-dealers and their institutional investor clients, while applying technology to eliminate weaknesses in traditional trading methods. In 2006,Creditmagazine recognized MarketAxess as “Best Multi-dealer Corporate Bond Trading Platform” in Europe.

Some of the innovations we have introduced to electronic trading include:


	•	the first multi-dealer disclosed trading platform for U.S. high-grade corporate bonds;

	•	the first electronic Treasury benchmarking for U.S. high-grade corporate bond trades;

	•	Corporate BondTicker, our information services product, combining NASD TRACE bond data with MarketAxess data and analytical tools;

	•	bid and offer list technology for corporate bond trading, enabling institutional investors to request executable prices for multiple securities simultaneously;

	•	the firstclient-to-dealer trading platform for CDS indices, enablingsame-day confirmation of new and assigned trades through the Depository Trust and Clearing Corporation; and

	•	DealerAxess^®, an innovativedealer-to-dealer electronic trading platform for U.S. high-grade corporate and emerging market bonds.

Our Strategy

Our objective is to provide the leading global electronic trading platform for fixed-income securities, connecting broker-dealers and institutional investors more easily and efficiently, while offering a broad array of services to market participants across the trading cycle. The key elements of our strategy are:

Enhance the Liquidity of Securities Traded on Our Platform and Broaden Our Client Base in Our Existing Markets

We intend to further enhance the liquidity of securities traded on our leading electronic, multi-dealer to client fixed-income platform. Our ability to innovate and efficiently add new functionality and product offerings to the MarketAxess platform will help us deepen our market share with our existing clients, as well as expand our client base, which we believe will in turn lead to even further increases in the liquidity of the securities provided by our broker-dealer clients and available on our platform. We will seek to make our current product offerings on our European electronic trading platform available to our 460 active U.S. institutional investor clients (firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006) and to increase the number of active European institutional investor clients (229 firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006) using our U.S. electronic trading platform, in each case subject to regulatory requirements.

Leverage our Existing Technology and Client Relationships to Expand into New Sectors of the Fixed-Income Securities Market

We intend to leverage our technology, as well as our strong broker-dealer and institutional investor relationships, to deploy our electronic trading platform into additional product segments within the fixed-income securities market. Due in part to our highly scalable systems, we believe we will be able to enter new markets efficiently.

Leverage our Existing Technology and Client Relationships to Expand into New Client Segments

We intend to leverage our technology and client relationships to deploy our electronic trading platform into new client segments. For example, we believe that the launch of CDS index trading on our platform will enable us to increase volumes from our hedge fund clients, as this client segment is an active user of CDS. As another example, in June 2006 we introduced our DealerAxess^® service, which allows our broker-dealer clients to transact U.S. corporate and emerging markets bond trades on our platform with other broker-dealer clients.

Continue to Strengthen and Expand our Trade-Related Service Offerings

We plan to continue building our existing service offerings so that our electronic trading platform is more fully integrated into the workflow of our broker-dealer and institutional investor clients. We also plan to continue to add functionality to enhance the ability of our clients to achieve a fully automated,end-to-end straight-through processing solution (automation from trade initiation to settlement). We are continually considering the introduction of new trading techniques. As an example, we have the technology necessary to offer an anonymous trading protocol that could be exported to other markets and sectors of fixed-income securities if and when client demand for such a product arises.

Expand our Data and Information Services Offerings

We regularly add new content and analytical capabilities to Corporate BondTicker in order to improve the value of the information we provide to our clients. Examples of added content include pricing for syndicated loans and credit derivatives, and independent credit research. We intend to enter into distribution agreements with information and data services companies in order to widen the user base of our data products and to continue adding new content and analytical capabilities. In July 2005, we entered into an agreement with Interactive Data Corporation, through its subsidiary, FT Interactive Data, to promote and market Corporate BondTicker. We expect this and other distribution partnerships to broaden our presence in the marketplace and increase our brand awareness. We intend to seek out additional market leaders in various segments of the securities industry and leverage their existing customer bases and distribution channels to further our data services market penetration.

We introduced compliance reporting tools for our institutional investor clients in November 2006 that assist them in monitoring best execution requirements for fixed income trades.

As the use of our electronic trading platform continues to grow, we believe that the amount and value of our proprietary trading data will also increase, further enhancing the value of our information services offerings to our clients.

Pursue Strategic Alliances and Select Acquisitions

We plan to continue to increase and supplement our internal growth by entering into strategic alliances, or acquiring businesses or technologies, that will enable us to enter new markets, provide new products or services, or otherwise enhance the value of our platform to our clients.

CurrentClient-to-Dealer Markets

U.S. High-Grade Corporate Bonds

Our U.S. high-grade corporate bond business consists of U.S. dollar-denominated investment-grade debt issued by corporations for distribution in the U.S. Institutional investors based in the U.S., as well as institutional investors located in the U.K., Germany, Belgium, Switzerland, Sweden, Norway, Hong Kong and Singapore, have access to U.S. high-grade corporate bond trading on our electronic trading platform. Investment-grade debt typically refers to debt rated BBB− or better by Standard & Poor’s and Baa3 or better by Moody’s Investor Service. We use the terms high-grade debt and investment-grade debt interchangeably in this annual report onForm 10-K. Our trading volume in the U.S. high-grade corporate bond market increased from $10.0 billion in 2001 to $195.4 billion in 2006. The majority of trading in U.S. high-grade corporate bonds is still conducted by telephone.

In the U.S. high-grade corporate bond market, 19 broker-dealers utilize our platform, including 17 of the top 20 broker-dealers as ranked by 2006 new-issue underwriting volume. The 19 broker-dealers who utilize our U.S. high-grade platform are: ABN AMRO, Banc of America Securities, Barclays PLC, Bear Stearns, BNP Paribas, Citigroup Global Markets, Credit Suisse, Deutsche Bank Securities, FTN Financial, Goldman Sachs, HSBC, JPMorgan, Jefferies and Company, Lehman Brothers, Merrill Lynch, Morgan Stanley, The Royal Bank of Scotland, UBS and Wachovia Securities.

Four hundred sixty active institutional investor clients (firms that executed at least one trade through our electronic trading platform between January 2006 and December 2006) utilize our electronic trading platform to trade U.S. high-grade corporate bonds. We offer our institutional investor clients access to a broad inventory of U.S. high-grade corporate bonds, which is provided and updated daily by our broker-dealer clients. Our electronic trading platform is a multi-dealer disclosed counterparty model, which allows institutional investors to view bids and offers from one or more of our broker-dealer clients while permitting each party to know the identity of its counter-party throughout the trading process. By disclosing the counterparties, the inquiry system on which our trading platform is based combines the strength of existing offline client/dealer relationships with the efficiency and transparency of an electronic trading platform. This enables institutional investors to instantly direct trade inquiries and negotiations to their traditional broker-dealer or to any of the overwhelming majority of the world’s leading broker-dealers who provide liquidity in these securities. Institutional investors have access to the commingled inventory of our broker-dealer clients, representing indicative bids and offers. Each line item of inventory represents an indicative bidand/or offer on a particular bond issue by a particular broker-dealer client. Institutional investor clients are not restricted to trading only the bonds posted as inventory, although many of the trades conducted on our platform are made from the posted inventory. To transact in a specific bond that does not appear in inventory, institutional investors can easily search our database and submit an online inquiry to their chosen broker-dealers, who can respond with live, executable prices. In a single inquiry, institutional investors can request bids or offers from up to all 19 of our U.S. broker-dealer clients. While, on average, institutional investor clients receive several bids or offers from broker-dealers in response to trade inquiries, some inquiries may not receive any bids or offers.

European High-Grade Corporate Bonds

The European high-grade corporate bond market consists of a broad range of products, issuers and currencies. We define the European high-grade corporate bond market generally to consist of bonds intended to be distributed to European investors, primarily bonds issued by European corporations, excluding bonds that are issued by a corporation domiciled in an emerging markets country and most government bonds that trade in Europe. Examples include:


	•	bonds issued by European corporations, denominated in any currency;

	•	bonds generally denominated in Euros, U.S. dollars or Pounds Sterling, excluding bonds that are issued by a corporation domiciled in an emerging market;

	•	bonds issued by supra-national organizations (entities that include a number of central banks or government financial authorities, such as the World Bank), agencies and governments located in Europe, generally denominated in Euros, U.S. dollars or Pounds Sterling, provided that such currency is not the currency of the country where the bond was issued; and

	•	floating-rate notes issued by European corporations.

MarketAxess Europe Limited, our wholly-owned U.K. subsidiary, commenced trading operations in August 2001. MarketAxess Europe Limited received Financial Services Authority (“FSA”) regulatory approval and began to offer European secondary trading functionality in U.S. dollar- and Euro-denominated European corporate bonds to our broker-dealer and institutional investor clients in September 2001. In 2003, we added trading in other European high-grade corporate bonds, including bonds issued in Pounds Sterling and floating rate notes. As on our U.S. electronic trading platform, all trading on our European platform is done using a multi-dealer disclosed counterparty model. We offered the first platform in Europe with this capability for corporate bonds.

In the European high-grade credit market, 20 broker-dealers utilize our platform, including 16 of the top 20 broker-dealers as ranked by 2006 new-issue underwriting volume of European corporate bonds. The 20 broker-dealers who utilize our European platform are: ABN AMRO, Banc of America Securities, Barclays PLC, Bear Stearns, BNP Paribas, Citigroup Global Markets, Credit Suisse, Deutsche Bank Securities, Dresdner Bank AG, DZ Bank AG, Goldman Sachs, HSBC, JPMorgan, Lehman Brothers, Merrill Lynch, Morgan Stanley, RBC Capital Markets, The Royal Bank of Scotland, SG Corporate and Investment Banking and UBS.

The 229 active institutional investor clients (firms that executed at least one trade through our European electronic trading platform between January 2006 and December 2006) that utilize our platform for trading European high-grade corporate bonds are based outside of the U.S. On a typical day, institutional investors on our European corporate bond trading platform have access to 18,000 line items of commingled inventory, representing an aggregate of approximately $90 billion of indicative bids and offers. In a single inquiry, institutional investors can request bids or offers from up to six of the broker-dealers who participate on the European platform. While many of the trades conducted on our platform are made from the posted inventory, institutional investor clients are not restricted to trading only the bonds posted as inventory. To transact in a specific bond that does not appear in inventory, institutional investors can easily search our database and submit an online inquiry to their chosen broker-dealers, who can respond with live, executable prices. While, on average, institutional investor clients receive several bids or offers from broker-dealers in response to trade inquiries, some inquiries may not receive any bids or offers. Our 2006 trading volume in the European high-grade corporate bond market was $87.6 billion. We have not identified a reliable source of data relating to the total volume ofclient-to-dealer trading in the European high-grade corporate bond market and, therefore, we are unable to determine the portion of this trading that takes place on our platform. The majority of trading in European high-grade corporate bonds is currently conducted by telephone.

Emerging Markets Bonds

We define the emerging markets bond market generally to include U.S. dollar- or Euro-denominated bonds issued by sovereign entities or corporations domiciled in a developing country. These issuers are typically located in Latin America and Eastern Europe. The emerging markets countries whose bonds were most frequently traded on our platform in 2006 were Brazil, Mexico, Argentina, Russia and Venezuela.

Eighteen of our U.S. broker-dealer clients use our platform to trade emerging markets bonds. Institutional investor clients can direct an inquiry simultaneously to up to eight of these 18 participating broker-dealer clients. While, on average, institutional investor clients receive several bids or offers from broker-dealers in response to trade inquiries, some inquiries may not receive any bids or offers.

We have not identified a reliable source of data relating to the total volume ofclient-to-dealer trading in emerging markets bonds and, therefore, we are unable to determine the portion of this trading that is taking place on our platform. The majority of trading in emerging markets bonds is currently conducted by telephone.

Crossover and High-Yield Bonds

We define the high-yield bond market generally to include all debt rated lower than BBB- by Standard & Poor’s or Baa3 by Moody’s Investor Service. We define the crossover market to include any debt issue rated below investment grade by one agency but investment grade by the other. The total amount of high-yield corporate bonds yearly issuance has grown from $130.9 billion as of December 31, 2003 to approximately $149.1 billion as of December 31, 2006.

Eighteen of our U.S. broker-dealer clients use our platform to trade crossover and high-yield bonds. Institutional investor clients can direct an inquiry simultaneously to up to all 18 of the participating broker-dealer clients.

The average daily trading volume of high-yield bonds reported by the NASD for the year ended December 31, 2006 was $4.8 billion.

Agency Bonds

We define the agency bond market to include debt issued by a U.S. government-sponsored agency. The offerings of these agencies are backed by, but not guaranteed by, the U.S. government. Some prominent issuers of agency bonds are Sallie Mae, Fannie Mae and Freddie Mac. The total amount of U.S. agency bonds outstanding has grown from $1.9 trillion as of December 31, 2000 to $2.7 trillion as of December 31, 2006.

Ten of our U.S. broker-dealer clients use our platform to trade agency bonds. Institutional investor clients can direct an inquiry simultaneously to up to all ten of the participating broker-dealer clients.

Credit Default Swaps

We launched CDS index trading on our platform in September 2005 and added the capacity to trade lists of single-name CDS in November 2006. In addition to the trading features, the index trading platform provides basic STP connectivity to dealers, clients and the Depository Trust & Clearing Corporation’s wholly-owned subsidiary, Deriv/SERV, a full-service provider of automated trade processing solutions in the OTC derivatives market. We also subscribe to Markit Group Limited’s RED service, the industry standard for reference entity and reference obligation identifiers in the credit derivatives market. The Markit RED data will help us achieve straight-through processing for its institutional investor clients from pre-trade through confirmation.

Fourteen of our U.S. broker-dealer clients are live on our platform to trade CDS indices and nine for CDS single-name lists.

CurrentDealer-to-Dealer Markets

U.S. High-Grade Corporate Bonds

In the U.S. high-grade corporate bond market, 19 broker-dealers utilize our DealerAxess^® platform to trade with each other. These dealers include 17 of the top 20 broker-dealers as ranked by 2006 new-issue underwriting volume. DealerAxess^® provides live inter-dealer markets utilizing proprietary cross-matching technology.

Although DealerAxess^® is a completely segregated trading platform, it shares the same core technology as ourclient-to-dealer platform.

The platform provides a documented record of orders and executed trades with reporting that enables broker-dealer clients to track, analyze and evaluate their inter-dealer trading. Straight-through processing is available to reduce manual tasks and lower the number of errors.

We estimate that inter-dealer trading represents approximately 25% of the reported NASD TRACE volume in U.S. high-grade corporate bonds. In 2006, the reported NASD TRACE volume for U.S. high-grade corporate bonds was $2.6 trillion. The majority of inter-dealer trading in U.S. high-grade corporate bonds is currently conducted by telephone through voice brokers.

Trades on DealerAxess^® are conducted with MarketAxess as riskless principal. Trades are cleared and settled by an independent clearing broker.

Emerging Markets Bonds

Twelve of our broker-dealer clients use our DealerAxess^® platform to trade emerging markets bonds with each other. The platform is primarily utilized for transactions in U.S. dollar denominated bonds issued by Latin American governments. Many of the same features available on DealerAxess^® for the trading of U.S. high-grade corporate bonds are available for emerging markets bonds.

We have not identified a reliable source of data relating to the total volume of inter-dealer trading in emerging markets bonds and, therefore, we are unable to determine the portion of this trading that is taking place on our platform. The majority of inter-dealer trading in emerging markets bonds is currently conducted by telephone through voice brokers.

Key Trading Functionalities

We currently offer both disclosed inquiry trading on ourclient-to-dealer platform and an anonymous cross matching style of trading on ourdealer-to-dealer platform. Our DealerAxess^®dealer-to-dealer trading platform provides anonymous live markets with executable bids and offers posted by participating dealers that are matched using proprietary cross-matching technology. The key trading functionalities on ourclient-to-dealer trading platform are detailed below.

Single Inquiry Trading Functionality

We currently offer institutional investors the ability to request bids or offers in a single inquiry from up to 19 of our broker-dealer clients for U.S. high-grade corporate bonds, from up to six of our broker-dealer clients for European high-grade corporate bonds and from up to eight of our broker-dealer clients in emerging markets bonds. Institutional investors can obtain bids or offers on any security posted in inventory or included in the database available on our platform.

ASAP and Holding Bin Trading Functionalities

We provide both ASAP (“as soon as possible”) and Holding Bin trading protocols. In the Holding Bin trading protocols, institutional investor clients set the time when they would like all of the broker-dealers’ prices or spreads returned to them, in order to have the ability to see all executable prices available at the same time. In the ASAP trading protocol, institutional investor clients see each broker-dealer’s price or spread as soon as it is entered by the broker-dealer.

List Trading Functionality

We currently offer institutional investors the ability to request bids or offers on a list of bonds, with the number of different bonds on each list varying between 8 and 25 items depending on the market. This facilitates efficient trading for institutional investors such as mutual funds and hedge funds. Institutional investors are able to have

multiple lists executable throughout the trading day, enabling them to manage their daily cash flows, portfolio duration, and credit and sector exposure.

Swap Trading Functionality

We currently offer institutional investors the ability to request an offer to purchase one bond and a bid to sell another bond, in a manner such that the two trades will be executed simultaneously, with payment based on the price or yield differential of the securities.

Information and Analytical Tools

Corporate BondTicker^tm

Corporate BondTicker provides real-time NASD TRACE data and enhances it with MarketAxess trade data and analytical tools to provide professional market participants with a comprehensive set of corporate bond price information. The data include trade time and sales information, including execution prices, as well as MarketAxess-estimatedspread-to-Treasuries, for trades disseminated by the NASD TRACE system. The data also include actual execution prices andspread-to-Treasury levels for U.S. high-grade corporate bond trades executed on the MarketAxess platform. Corporate BondTicker allows institutional investors to search for and sort bonds based upon specific criteria, such as volume, time/date of transaction, spread change, issuer or security. This search function allows institutional investors to compile information relating to potential securities trades in a fraction of the time that it takes to manually compile this information from disparate sources or other electronic databases, including direct TRACE feeds. In addition, Corporate BondTicker provides independent credit research, as well as indicative prices for secondary markets in loans and credit default swaps.

TRACE facilitates the mandatory reporting ofover-the-counter secondary market transactions in eligible fixed-income securities. All broker-dealers that are NASD member firms have an obligation to report transactions in corporate bonds to TRACE under a set of rules approved by the U.S. Securities and Exchange Commission (“SEC”). The NASD then publicly disseminates a portion of this data, which is available free of charge on a delayed basis through the NASD website or available immediately for a set fee.

Corporate BondTicker is integrated directly into the MarketAxess electronic trading platform and can be seamlessly accessed, either when viewing securities inventory or when launching an inquiry. Corporate BondTicker is also available through the Internet for non-trading professional market participants, including, among others, research analysts and rating agencies, who can log in and access the information via aneasy-to-use browser-based interface.

We provide Corporate BondTicker as an ancillary service to our trading clients and also to other industry participants. We derive revenues from our Corporate BondTicker service by charging for seat licenses per user at our broker-dealer and institutional investor clients, through distribution agreements with other information service providers and through bulk data sales to third parties. Seat license fees from institutional investor clients are waived for clients that transact a sufficient volume of trades through MarketAxess.

Additional analytical capabilities of our information services offerings aim to provide clients with more information about bond prices and market activity, including asset swap spreads, turnover percentage and liquidity ratios. These statistics measure a security’s trading activity relative to its amount outstanding and relative to the overall market, respectively, providing an additional perspective on relative liquidity. In addition, we provide pricing measures to help institutional investors better assess the relative value of a corporate bond, providing more consistent relative pricing information for institutional investors, such as offering spread data versus the interest rate swap curve and versus the U.S. Treasury curve. Users are also able to download a variety of MarketAxess-compiled trade reports containing a comprehensive review of trading activity. Corporate BondTicker is currently the source of corporate bond trading information forThe Wall Street Journal.

quantitative measure of the value of price discovery from multiple dealers. The report allows clients to monitor performance against their own best execution policy. Our compliance product provides a printed history of each inquiry submitted through the MarketAxess trading platform.

My Portfolio

Institutional investors are able to upload their corporate bond portfolio onto our electronic trading platform utilizing the “My Portfolio” trading feature. Institutional investors who utilize “My Portfolio” benefit from the ability to automatically match inventory on our platform to bonds held in their portfolio, allowing them to more efficiently launch an inquiry and transact in these securities. Users of this feature can also directly access Corporate BondTicker to obtain the trading history of the securities in their portfolio.

Straight-Through Processing

Straight-through processing refers to the integration of systems and processes to automate the trade process fromend-to-end — trade execution, confirmation and settlement — without the need for manual intervention. There are two elements of straight-through processing: internal straight-through processing and external straight-through processing. Internal straight-through processing relates to the trade and settlement processes that are internal to an industry participant. For example, in the case of an institutional investor, this includes authorization of orders, placement of orders with broker-dealers, receipt of execution details and allocation of trades. External straight-through processing refers to connecting seamlessly to all external counterparts in the trading and settlement process.

Automation by way of straight-through processing improves the efficiency of the trade cycle. We provide broker-dealers and institutional investors with a range of tools that facilitate straight-through processing, including order upload,easy-to-use online allocation tools and pre- and post-trade messaging features that enable institutional investors to communicate electronically between front- and back-office systems, thereby integrating the order, portfolio management and accounting systems of our broker-dealer and institutional investor clients in real time. Our straight-through processing tools can be customized to meet specific needs of clients. We continue to build industry partnerships to assist our clients in creating connectivity throughout the trade cycle. Through these partnerships, we are increasingly providing solutions that can quickly be deployed within our clients’ trading operations.

Usage of our straight-through processing tools increased significantly during 2006. In our U.S. high-grade corporate bond business between 2005 and 2006, the number of orders uploaded electronically increased from 5,459 to 32,056. The number of online allocations increased from 58,847 to 83,469 and the number of completed trades delivered to institutional investor clients through our post-trade messaging functionality increased from 17.5% to 53.2% of total volume.

Dealer API

We offer Application Program Interface (API) services to our broker-dealer clients for pre-trade, trade negotiation and post-trade services. This allows for straight-through processing, which improves efficiency and reduces errors in processing.

Dependence on Our Broker-Dealer Clients Who Are Also Our Stockholders

Revenues

We have historically earned the majority of our commissions and revenues from nine broker-dealer clients (ABN Amro, BNP Paribas, Banc of America, Bear Stearns, Credit Suisse, Deutsche Bank, JPMorgan, Lehman Brothers and UBS) that were (or whose affiliates were) also our stockholders as of January 1, 2006. Affiliates of most of our broker-dealer clients are also among our institutional investor clients. Information relating to the percentage of our commissions and the percentage of our revenues generated by these nine broker-dealer clients is provided in the chart below:


	Year Ended December 31,
	2006			2005			2004

Percentage of commissions		49.9	%		54.7	%		57.7	%
Percentage of total revenues		46.0	%		49.7	%		53.6	%

As of December 31, 2006, these nine broker-dealer clients owned 10,748,233 shares or 31.6% of our common stock on a diluted basis, assuming conversion of our non-voting common stock and exercise of warrants in exchange for common stock. To the extent that some or all of these broker-dealer clients or their affiliates vote similarly, they are likely to be able to influence decisions requiring approval by our stockholders.

Our broker-dealer clients are not restricted from buying and selling fixed-income securities, directly or through their own proprietary or third-party platforms, with institutional investors. For more information, see “Item 1A.,Risk Factors — Risk Factors That May Affect Future Results — We are dependent on our broker-dealer clients, nine of which were also our stockholders as of January 1, 2006, who are not restricted from buying and selling fixed-income securities, directly or through their own proprietary or third-party platforms, with institutional investors.”

Board of Directors

We currently have nine directors, eight of whom are not our employees. Of the eight non-employee directors, two are employees of entities that are affiliates of broker-dealer clients and stockholders of MarketAxess, although these entities do not have the contractual right to designate members of our Board of Directors.

Other Businesses

Our broker-dealer clients currently trade fixed-income securities by means other than our electronic trading platform and we expect them to continue to do so in the future. Our broker-dealer clients buy and sell fixed-income securities directly with their clients through traditional bond trading methods, including telephone conversations,e-mail messaging and other electronic means of communication, including proprietary, single-dealer systems.

We cannot be assured that such broker-dealers’ primary commitments will not be to one of our competitors. Other companies, including some in which certain of our broker-dealer clients or their affiliates have invested, have developed electronic trading platforms or have announced their intention to explore the development of electronic trading platforms that compete or will compete with us. Furthermore, our broker-dealer clients or their affiliates have made, or may in the future make investments in or enter into agreements with other businesses that directly or indirectly compete with us.

Conflicts of Interest

Information concerning the potential conflicts of interest that may arise as a result of the various roles (broker-dealer client and stockholder) played by certain of our broker-dealer clients, please see “Item 1A.,Risk Factors — Risk Factors That May Affect Future Results — Risks Related to the Potential Conflicts of Interest With Our Broker-Dealer Clients Who Are Also Our Stockholders.”

Sales and Marketing

We promote our products and services using a variety of direct and indirect sales and marketing strategies. Our sales force is organized into four teams: U.S. client sales, European client sales, U.S. dealer relations and European dealer relations. They are responsible for client acquisition activity and for increasing use of our platform by our existing clients. Their goal is to train and support existing and new clients on how to use the system and to educate them as to the benefits of utilizing an electronic fixed-income trading platform. We employ various strategies, including advertising, direct marketing, promotional mailings and participation in industry conferences, to increase awareness of our brand and our electronic trading platform. For example, we have worked withThe Wall Street Journalto establish Corporate BondTicker as the source of information for its daily corporate bond and high-yield tables.

Competition

The electronic trading industry is highly competitive and we expect competition to intensify in the future. We face four main areas of competition:


	•	Telephone — We compete with bond trading business conducted over the telephone between broker-dealers and their institutional investor clients. Institutional investors have historically purchased fixed-income securities by telephoning bond sales professionals at one or more broker-dealers and inquiring about the price and availability of individual bonds. This remains the manner in which the majority of corporate bonds are still traded between institutional investors and broker-dealers.

	•	E-mail — We compete with bond trading business conducted viae-mail between broker-dealers and their institutional investor clients.E-mail provides an efficient means of initiating product and price discovery with a large universe of potential trading partners.

	•	Other electronic trading platforms — There are numerous other electronic trading platforms currently in existence. These include Thomson TradeWeb, a multi-dealer to institutional investor trading platform that has historically focused on government bond trading, and Bloomberg, which provides electronic trading functionality. In 2002, Thomson TradeWeb launched an electronic corporate bond trading platform. In addition, some broker-dealers operate proprietary electronic trading systems that enable institutional investors to trade directly with a broker-dealer over an electronic medium. We believe that we are currently the only platform primarily focused on multi-party disclosed trading of credit products between broker-dealers and institutional investors, though others have or may seek to expand their product offerings to compete in this market. Additionally, as we expand our business into new products, we will likely come into more direct competition with other electronic trading platforms or firms offering traditional services. For instance, our DealerAxess^® platform competes with services offered by voice brokerage firms including BGC Partners L.P., GFI Group Inc., ICAP plc and Tullet Prebon plc.

	•	Market data and information vendors — Several large market data and information providers currently have a data and analytics relationship with virtually every institutional firm. Some of these entities currently offer varying forms of electronic trading of fixed-income securities, mostly on a single-dealer basis. Some of these entities have announced their intention to expand their electronic trading platforms or to develop new platforms. These entities are currently direct competitors to our information services and may in the future become direct competitors to our electronic trading platform.

Competitors, including companies in which some of our broker-dealer clients have invested, have developed electronic trading platforms or have announced their intention to explore the development of electronic trading platforms that compete or will compete with us. Furthermore, our broker-dealer clients have made, or may in the future make investments in or enter into agreements with other businesses that directly or indirectly compete with us.

In general, we compete on the basis of a number of key factors, including:


	•	liquidity provided on the electronic trading platform;

	•	magnitude and frequency of price improvement;


	•	facilitating the quality and speed of execution;

	•	total transaction costs;

	•	technology capabilities, including the ease of use of our electronic trading platform; and

	•	range of products and services offered.

We believe that we compete favorably with respect to these factors. Our trading volume and client acceptance have grown over the past three years and we continue to proactively build technology solutions that serve the needs of the credit markets.

Our competitive position is also enhanced by the familiarity and integration of our broker-dealer and institutional investor clients with our electronic trading platform and other systems. We have focused on the unique aspects of the credit markets we serve in the development of our platform, working closely with our clients to provide a system that is suited to their needs.

Our broker-dealer clients have invested in building application programming interfaces with us for inventory contributions, electronic trading, government bond benchmark pricing and post-trade messaging. We believe that we have successfully built deep roots with our broker-dealer clients, increasing our level of service to them while at the same time increasing their commitment to our services.

Furthermore, approximately 100 of our institutional investor clients have built interfaces to enable them to communicate electronically between our platform and their order, portfolio management and accounting systems. We believe that this increases the commitment of these institutional investor clients to our services.

Many of our current and potential competitors are more established and substantially larger than we are and have substantially greater market presence, as well as greater financial, engineering, technical, marketing and other resources. These competitors may aggressively reduce their pricing to enter into market segments in which we have a leadership position today, potentially subsidizing any losses with profits from trading in other securities. In addition, many of our competitors offer a wider range of services, have broader name recognition and have larger customer bases than we do. Some of them may be able to respond more quickly to new or evolving opportunities, technologies and customer requirements than we can and may be able to undertake more extensive promotional activities.

Any combination of our competitors or our current broker-dealer clients may enter into joint ventures or consortia to provide services similar to those provided by us. Current and new competitors can launch new platforms at a relatively low cost. Others may acquire the capabilities necessary to compete with us through acquisitions. Significant consolidation has occurred in our industry and these firms, as well as others that may undertake such consolidation in the future, are potential competitors of ours.

Technology

The design and quality of our technology are critical to our growth and our ability to execute our business strategy. Our electronic trading platform has been designed with secure, scalable, client-server architecture that makes broad use of distributed computing to achieve speed, reliability and fault tolerance. The platform is built on industry-standard technologies and has been designed to handle multiples of our current trading volume.

All critical server-side components, primarily our networks, application servers and databases, have backup equipment running in case the main equipment fails. This offers fully redundant system capacity to maximize uptime and minimize the potential for loss of transaction data in the event of an internal failure. We also seek to minimize the impact of external failures by automatically recovering connections in the event of a communications failure. The majority of our broker-dealer clients have dedicated high-speed communication lines to our network in order to provide fast data transfer. Our security measures include industry-standard communications encryption.

We have designed our application with aneasy-to-use, Windows-based interface. Through a secure, single sign-on, our clients are able to access our electronic trading platform. We provide users an automatic software update feature that does not require manual intervention.

Intellectual Property

We rely upon a combination of copyright, patent, trade secret and trademark laws, written agreements and common law to protect our proprietary technology, processes and other intellectual property. Our software code, elements of our electronic trading platform, Web site and other proprietary materials are protected by copyright laws. We currently have six patent applications pending, covering certain aspects of our business.

The written agreements upon which we rely to protect our proprietary technology, processes and intellectual property include agreements designed to protect our trade secrets. Examples of these written agreements include third party nondisclosure agreements, employee nondisclosure and inventions assignment agreements, and agreements with customers, contractors and strategic partners. Other written agreements upon which we rely to protect our proprietary technology, processes and intellectual property take many forms and contain provisions related to patent, copyright, trademark or trade secret rights.

We have obtained U.S. federal registration of the MarketAxess^® name and logo, and the same mark and logo have been registered in several foreign jurisdictions. We have pending registrations for the MarketAxess^® name and logo in several other foreign jurisdictions. In addition, we have obtained U.S. federal registration for the marks AutoSpotting^®, BondLink^®, FrontPage^®, Actives^®, DealerAxess^® and associated designs. “Corporate BondTicker” is a trademark we use, but it has not been registered.

In addition to our efforts to register our intellectual property, we believe that factors such as the technological and creative skills of our personnel, new service developments, frequent enhancements and reliability with respect to our services are essential to establishing and maintaining a technology and market leadership position.

Government Regulation

The securities industry and financial markets in the U.S. and elsewhere are subject to extensive regulation. As a matter of public policy, regulatory bodies in the U.S. and the rest of the world are charged with safeguarding the integrity of the securities and other financial markets and with protecting the interests of investors participating in those markets. Our active broker-dealer subsidiaries fall within the scope of their regulations.

Regulation of the U.S. Securities Industry and Broker-Dealers

In the U.S., the SEC is the governmental agency responsible for the administration of the federal securities laws. Our U.S. subsidiary, MarketAxess Corporation, is registered with the SEC as a broker-dealer. It is also a member of the NASD, a self-regulatory organization to which most broker-dealers belong. In addition, MarketAxess Corporation is a member of the Securities Investor Protection Corporation, which provides certain protection for clients’ accounts in the event of a liquidation of a broker-dealer to the extent any such accounts are held by the broker-dealer.

Additionally, MarketAxess Corporation is registered with certain states and the District of Columbia as a broker-dealer. The states and the District of Columbia are responsible for the administration of their respective “blue sky” laws, rules and regulations.

Regulation of theNon-U.S. Securities Industries and Investment Service Providers

The securities industry and financial markets in the U.K., the European Union and elsewhere are subject to extensive regulation. MarketAxess Europe Limited may fall within the scope of those regulations depending upon the extent to which it is characterized as providing a regulated investment service.

Our principal regulator in the U.K. is the FSA. Our U.K. subsidiary, MarketAxess Europe Limited, is registered as an alternative trading system (“ATS”) with the FSA.

The securities industry in the member states of the European Union is regulated by agencies in each member state. European Union measures provide for the mutual recognition of regulatory agencies and of prudential supervision making possible the grant of a single authorization for providers of investment services which, in general, is valid throughout the European Union. As an FSA-approved ATS, MarketAxess Europe Limited receives the benefit of this authorization.

In May 2003, we incorporated a Canadian subsidiary, MarketAxess Canada Limited. It has applied for registration as an ATS under the Securities Act of Ontario and is in the process of seeking approval for membership with the Investment Dealers Association of Canada.

Employees

As of December 31, 2006, we had 176 employees, 143 of whom were based in the U.S. and 33 of whom were based in the U.K. None of our employees are represented by a labor union. We consider our relationships with our employees to be good and have not experienced any interruptions of operations due to labor disagreements.

Item 1A.	*Risk Factors*

Risks Related to the Potential Conflicts of Interest With Our Broker-Dealer Clients
Who Are Also Our Stockholders

We are dependent on our broker-dealer clients, nine of which were also our stockholders as of January 1, 2006, who are not restricted from buying and selling fixed-income securities, directly or through their own proprietary or third-party platforms, with institutional investors.

We rely on our broker-dealer clients to provide product and liquidity on our electronic trading platform by posting bond prices on our platform for bonds in their inventory and responding to institutional investor client inquiries. Although each broker-dealer client is currently a party to an agreement with us, the obligations of each broker-dealer under these agreements are minimal. None of these agreements is exclusive and broker-dealers may terminate such agreementsand/or enter into, and in some cases have entered into, similar agreements with our competitors. For example, some of our broker-dealer clients are also clients of Thomson TradeWeb, a multi-dealer to institutional investor trading platform that operates an online corporate bond trading platform.

Our broker-dealer clients buy and sell fixed-income securities directly with their clients through traditional bond trading methods, including telephone conversations,e-mail messaging and other electronic means of communication. Currently, the preponderance of trading of U.S. high-grade corporate bonds still occurs using traditional bond trading methods. Most of our broker-dealer and institutional investor clients are involved in other ventures, including other electronic trading platforms or other distribution channels, as trading participantsand/or as equity holders, and such ventures or newly created ventures may compete with us and our electronic trading platform now and in the future.

Some of our broker-dealer clients have developed electronic trading networks or have announced their intention to explore the development of electronic trading networks. These competing trading platforms may offer some features that we do not currently offer. Furthermore, our broker-dealer clients have made, and may in the future continue to make, investments in businesses that directly or indirectly compete with us, including, either individually or collectively, organizing or investing in a separate company similar to us for the purpose of competing with us or pursuing corporate opportunities that might be attractive to us. Accordingly, there can be no assurance that such broker-dealers’ primary commitments will not be to one of our competitors.

Any reduction in the use of our electronic trading platform by our broker-dealer clients would reduce the number of different bond issues and the volume of trading in those bond issues on our platform, which could, in turn, reduce the use of our platform by our institutional investor clients. The occurrence of any of the foregoing may have a material adverse effect on our business, financial condition and results of operations.

We derive a significant percentage of our total revenues, and an even greater percentage of our commissions, from broker-dealer clients who are also our stockholders.

We have historically earned a substantial portion of our commissions from the nine broker-dealer clients that were our stockholders as of January 1, 2006. For the year ended December 31, 2006, $35.6 million or 49.9% of our commissions, for the year ended December 31, 2005, $36.6 million or 54.7% of our commissions, and for the year ended December 31, 2004, $39.3 million or 57.7% of our commissions, were generated by these nine broker-dealer clients. None of our broker-dealer clients is contractually or otherwise obligated to continue to use our electronic trading platform. Reduced involvement of these broker-dealer clients due to their lack of a right to designate a member of our Board of Directors or the potential reduction in the level of their equity ownership if these entities should sell shares of our common stock, may cause them to reduce or discontinue their use of our electronic trading platform and other services, which could negatively impact the use of our platform by our institutional investor clients. The loss of, or a significant reduction of, participation on our platform by these broker-dealer clients may have a material adverse effect on our business, financial condition and results of operations.

Several of our broker-dealer clients or their affiliates beneficially own a significant percentage of our outstanding common stock. These broker-dealer clients have strategic interests that differ from those of our other stockholders.

As of January 1, 2006, nine of our broker-dealer clients or their affiliates owned, in the aggregate, a significant percentage of our outstanding common stock. These broker-dealer clients have strategic interests that are different from ours and those of our other stockholders. For example, in their capacity as broker-dealer clients, they would presumably favor lower commissionsand/or commission caps. Furthermore, as stockholders in other consortia that have developed competitive electronic trading networks or have announced their intention to explore the development of competitive electronic trading networks, they may decide to direct some or all of their electronic trading business to one or more of our competitors. While these actions, if taken, would presumably reduce our revenues and our market capitalization and, therefore, the value of their ownership position in us, there can be no assurance that they will not decide to take such actions for their own strategic reasons.

We are not a party to any voting agreement with any of our stockholders and are not aware of any voting agreements among our broker-dealer clients; however, they may enter into a voting agreement in the future or otherwise vote in a similar manner. To the extent that all of these broker-dealer clients or their affiliates vote similarly, they will be able to determine decisions requiring approval by our stockholders. As a result, they or their affiliates may be able to:


	•	control the composition of our Board of Directors through their ability to nominate directors and vote their shares to elect them;

	•	control our management and policies; and

	•	determine the outcome of significant corporate transactions, including changes in control that may be beneficial to other stockholders.

As a result of these factors, we may be less likely to pursue relationships with strategic partners who are not stockholders of ours, which could impede our ability to expand our business and strengthen our competitive position. Furthermore, these factors could also limit stockholder value by preventing a change in control or sale of MarketAxess.

We may be limited in our use of our U.S. net operating loss carryforwards.

As of December 31, 2006, we had U.S. net operating loss carryforwards of $91.6 million, which will begin to expire in 2019. A net operating loss carryforward enables a company to apply net operating losses incurred during a current period against future periods’ profits in order to reduce tax liability in those future periods.

Section 382 of the Internal Revenue Code provides that when a company undergoes an “ownership change,” that company’s use of its net operating losses is limited annually in each subsequent year. An “ownership change” occurs when, as of any testing date, the sum of the increases in ownership of each shareholder that owns five percent or more of the value of a company’s stock compared to that shareholder’s lowest percentage ownership during the preceding three-year period exceeds 50 percentage points. For purposes of this rule, certain shareholders who own less than five percent of a company’s stock are aggregated and treated as a single five-percent shareholder.

In 2000 and 2001, MarketAxess Holdings Inc. and MarketAxess Corporation had an “ownership change.” As a result, net operating loss carryforwards of $39.2 million existing at the date of the ownership change are subject to significant limitations.

The issuance or repurchase of a significant number of shares of stock or purchases or sales of stock by significant shareholders could result in an additional “ownership change.” We may issue a substantial number of shares of our stock in connection with offerings, acquisitions and other transactions in the future, although no assurance can be given that any such offering, acquisition or other transaction will be undertaken, and we expect to repurchase a significant number of shares in connection with our stock repurchase program. In addition, the exercise of outstanding options to purchase shares of our common stock may require us to issue additional shares of our common stock. The extent of the actual future use of our U.S. net operating loss carryforwards is subject to inherent uncertainty because it depends on the amount of otherwise taxable income we may earn. We cannot give any

assurance that we will have sufficient taxable income in future years to use any of our federal net operating loss carryforwards before they would otherwise expire.

Risks Related to Our Business

We face substantial competition that could reduce our market share and harm our financial performance.

The fixed-income securities industry generally, and the electronic financial services markets in which we operate in particular, are highly competitive, and we expect competition to intensify in the future. We will continue to compete with bond trading conducted directly between broker-dealers and their institutional investor clients over the telephone or electronically. In addition, our current and prospective competitors are numerous and include:


	•	other multi-dealer trading companies;

	•	market data and information vendors;

	•	securities and futures exchanges;

	•	inter-dealer brokerage firms;

	•	electronic communications networks;

	•	technology, software, information and media or other companies that have existing commercial relationships with broker-dealers or institutional investors; and

	•	other electronic marketplaces that are not currently in the securities business.

Many of our current and potential competitors are more established and substantially larger than we are, and have substantially greater market presence, as well as greater financial, engineering, technical, marketing and other resources. These competitors may aggressively reduce their pricing to enter into market segments in which we have a leadership position today, potentially subsidizing any losses with profits from trading in other fixed-income or equity securities. In addition, many of our competitors offer a wider range of services, have broader name recognition and have larger customer bases than we do. Some of them may be able to respond more quickly to new or evolving opportunities, technologies and customer requirements than we can and may be able to undertake more extensive promotional activities.

Any combination of our competitors may enter into joint ventures or consortia to provide services similar to those provided by us. Current and new competitors can launch new platforms at a relatively low cost. Others may acquire the capabilities necessary to compete with us through acquisitions. We expect that we will potentially compete with a variety of companies with respect to each product or service we offer. If we are not able to compete successfully in the future, our business, financial condition and results of operations would be adversely affected.

We have experienced losses and may incur losses in the future.

Our losses were $16.8 million from the period of inception through December 31, 2000, $65.1 million for the year ended December 31, 2001 and $36.1 million for the year ended December 31, 2002. For the year ended December 31, 2003, we reported net income of $4.2 million, for the year ended December 31, 2004, we reported net income of $57.6 million, which included $46.1 million in income which was recognized upon our reassessment of the likelihood of realization of a portion of our deferred tax assets, for the year ended December 31, 2005, we reported net income of $8.1 million and for the year ended December 31, 2006, we reported net income of $5.4 million We cannot predict whether we will be able to sustain profitability and we may incur losses in future periods. If we are not able to sustain profitability, our stock price may decline.

Neither the sustainability of our current level of business nor our historical growth can be assured. Even if we do experience growth, we cannot assure you that we will grow profitably.

The use of our electronic trading platform is relatively new. The success of our business strategy depends, in part, on our ability to maintain and expand the network of broker-dealer and institutional investor clients that use our

electronic trading platform. Our business strategy also depends on increasing the use of our platform by these clients. Individuals at broker-dealers or institutional investors may have conflicting interests, which may discourage their use of our platform.

Our growth is also dependent on our ability to diversify our revenue base. We currently derive a majority of our revenues from secondary trading in U.S. high-grade corporate bonds. The percentage of our commissions from such trading remained relatively constant for the years ended December 31, 2006, 2005 and 2004. Our long-term business strategy is dependent on expanding our service offerings and increasing our revenues from other fixed-income products and other sources. We cannot assure you that our efforts will be successful or result in increased revenues or continued profitability.

Our plans to pursue other opportunities for revenue growth are at an early stage, and we cannot assure you that our plans will be successful or that we will actually proceed with them as described.

Because we have a limited operating history, it is difficult to evaluate our business and prospects.

MarketAxess was formed in April 2000 and pilot trading on our electronic trading platform began in October 2000, with the commercial launch of the platform in January 2001. As a result, we have only a limited operating history from which you can evaluate our business and our prospects. We will encounter risks and difficulties frequently experienced by early-stage companies in rapidly evolving industries, such as the electronic financial services industry. These risks and difficulties include, but are not limited to, our ability to:


	•	attract and retain broker-dealers and institutional investors on a cost-effective basis;

	•	expand and enhance reliable and cost-effective product and service offerings to our clients;

	•	respond effectively to competitive pressures;

	•	diversify our sources of revenues;

	•	maintain adequate control of our expenses;

	•	operate, support, expand and develop our operations, website, software, communications and other systems;

	•	manage growth in personnel and operations;

	•	increase awareness of our brand or market positioning;

	•	expand our sales and marketing programs; and

	•	respond to regulatory changes or demands.

If we are unsuccessful in addressing these risks or in executing our business strategy, our business, financial condition and results of operations may suffer.

Decreases in trading volumes in the fixed-income markets generally or on our platform could harm our business and profitability.

We have experienced decreases in overall trading volume in certain periods, and may experience decreases in trading volume in the future. Declines in the overall volume of fixed-income securities trading and in market liquidity generally, as well as declines in interest rate volatility, result in lower revenues from commissions for trades executed on our electronic trading platform and fees generated from related activities.

Likewise, decreases in our share of the segments of the fixed-income trading markets in which we operate, or shifts in trading volume to segments of clients which we have not penetrated, could result in lower trading volume on our platform and, consequently, lower commissions and other revenue. During periods of increased volatility in credit markets, the use of electronic trading platforms by market participants may decrease dramatically as institutional investors may seek to obtain additional information during the trade process through conversations with broker-dealers. In addition, during rapidly moving markets, broker-dealers may be less likely to post prices electronically.

A decline in trading volumes on our platform for any reason may have a material adverse effect on our business, financial condition and results of operations.

We may enter into new fee plans, the impact of which may be difficult to evaluate.

On June 1, 2005, we introduced a new fee plan primarily for secondary market transactions in U.S. high-grade corporate bonds executed on our electronic trading platform. Most of our U.S. high-grade broker-dealer clients signed new two-year agreements in 2005. These agreements are scheduled for renewal at various times between June 2007 and December 2007. In addition, we anticipate that from time to time we will introduce new fee plans for the other market segments in which we operate. Any new fee plan may include different fee structures or provide volume incentives.

We cannot assure you that any new fee plans will result in an increase in the volume of transactions effected on our platform or that our revenues will increase as a result of the implementation of any such plans. Furthermore, resistance to new fee plans by our broker-dealer or institutional investor clients could have a material adverse effect on our business, financial condition and results of operations.

We are exposed to risks resulting from non-performance by counterparties to transactions executed between our broker-dealer clients in which we act as an intermediary in matching back-to back trades.

In June 2006, we began executing riskless principal transactions between our broker-dealer clients through our subsidiary, MarketAxess Corporation. We act as an intermediary in these transactions by serving as counterparty to both the buyer and the seller in matchingback-to-back trades, which are then settled through a third-party clearing organization. Settlement typically occurs within one to three trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded.

We are exposed to credit risk in our role as trading counterparty to our broker-dealer clients executing trades on the DealerAxess^® platform. We are exposed to the risk that third parties that owe us money, securities or other assets will not perform their obligations. These parties may default on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. Adverse movements in the prices of securities that are the subject of these transactions can increase our risk. Where the unmatched position or failure to deliver is prolonged there may also be regulatory capital charges required to be taken by us. The policies and procedures we use to manage this credit risk are new and untested. There can be no assurance that these policies and procedures will effectively mitigate our exposure to credit risk.

If we experience significant fluctuations in our operating results or fail to meet revenues and earnings expectations, our stock price may fall rapidly and without advance notice.

Due to our limited operating history, our evolving business model and the unpredictability of our industry, we may experience significant fluctuations in our operating results. We base our current and future expense levels and our investment plans on estimates of future revenues and future rate of growth. Our expenses and investments are, to a large extent, fixed and we expect that these expenses will increase in the future. We may not be able to adjust our spending quickly enough if our revenues fall short of our expectations.

Our revenues and operating results may also fluctuate due to other factors, including:


	•	our ability to retain existing broker-dealer and institutional investor clients and attract new broker-dealers and institutional investor clients;

	•	our ability to drive an increase in use of our electronic trading platform by new and existing broker-dealer and institutional investor clients;

	•	changes in our pricing policies;

	•	the introduction of new features on our electronic trading platform;

	•	the effectiveness of our sales force;

	•	new product and service introductions by our competitors;


	•	fluctuations in overall market trading volume;

	•	technical difficulties or interruptions in our service;

	•	general economic conditions in our geographic markets;

	•	additional investment in our services or operations; and

	•	regulatory compliance costs.

As a result, our operating results may fluctuate significantly on a quarterly basis, which could result in decreases in our stock price.

We may not be able to introduce enhanced versions of our electronic trading platform, new servicesand/or service enhancements in a timely or acceptable manner, which could harm our competitive position.

Our business environment is characterized by rapid technological change, changing and increasingly sophisticated client demands and evolving industry standards. Our future will depend on our ability to develop and introduce new features to, and new versions of, our electronic trading platform. The success of new features and versions depends on several factors, including the timely completion, introduction and market acceptance of the feature or version. In addition, the market for our electronic trading platform may be limited if prospective clients require customized features or functions that we are unable or unwilling to provide. If we are unable to anticipate and respond to the demand for new services, products and technologies and develop new features and enhanced versions of our electronic trading platform that achieve widespread levels of market acceptance on a timely and cost-effective basis, it could have a material adverse effect on our business, financial condition and results of operations.

As we enter new markets, we may not be able to successfully attract clients and adapt our technology and marketing strategy for use in those markets.

Our strategy includes leveraging our electronic trading platform to enter new markets. We cannot assure you that we will be able to successfully adapt our proprietary software and technology for use in other markets. Even if we do adapt our software and technology, we cannot assure you that we will be able to attract clients and compete successfully in any such new markets. We cannot assure you that our marketing efforts or our pursuit of any of these opportunities will be successful. If these efforts are not successful, we may realize less than expected earnings, which in turn could result in a decrease in the market value of our common stock. Furthermore, these efforts may divert management attention or inefficiently utilize our resources.

Rapid technological changes may render our technology obsolete or decrease the attractiveness of our products and services to our broker-dealer and institutional investor clients.

We must continue to enhance and improve our electronic trading platform. The electronic financial services industry is characterized by increasingly complex systems and infrastructures and new business models. If new industry standards and practices emerge, our existing technology, systems and electronic trading platform may become obsolete or our existing business may be harmed. Our future success will depend on our ability to:


	•	enhance our existing products and services;

	•	developand/or license new products and technologies that address the increasingly sophisticated and varied needs of our broker-dealer and institutional investor clients and prospective clients; and

	•	respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis.

Developing our electronic trading platform and other technology entails significant technical and business risks. We may use new technologies ineffectively or we may fail to adapt our electronic trading platform, information databases and network infrastructure to broker-dealer or institutional investor client requirements or emerging industry standards. For example, our electronic trading platform functionality that allows searches and inquiries on bond pricing and availability is a critical part of our service, and it may becomeout-of-date or

insufficient from our broker-dealer clients’ or institutional investor clients’ perspective and in relation to the inquiry functionality of our competitors’ systems. If we face material delays in introducing new services, products and enhancements, our broker-dealer and institutional investor clients may forego the use of our products and use those of our competitors.

Further, the adoption of new Internet, networking or telecommunications technologies may require us to devote substantial resources to modify and adapt our services. We cannot assure you that we will be able to successfully implement new technologies or adapt our proprietary technology and transaction-processing systems to client requirements or emerging industry standards. We cannot assure you that we will be able to respond in a timely manner to changing market conditions or client requirements.

We depend on third-party suppliers for key products and services.

We rely on a number of third parties to supply elements of our trading, information and other systems, as well as computers and other equipment, and related support and maintenance. We cannot assure you that any of these providers will be able to continue to provide these services in an efficient, cost-effective manner, if at all, or that they will be able to adequately expand their services to meet our needs. If we are unable to make alternative arrangements for the supply of critical products or services in the event of a malfunction of a product or an interruption in or the cessation of service by an existing service provider, our business, financial condition and results of operations could be materially adversely affected.

In particular, we depend on a third-party vendor for our corporate bond reference database. Disruptions in the services provided by that third party to us, including as a result of their inability or unwillingness to continue to license products that are critical to the success of our business, could have a material adverse effect on our business, financial condition and results of operations.

We also rely, and expect in the future to continue to rely, on third parties for various computer and communications systems, such as telephone companies, online service providers, data processors, and software and hardware vendors. Other third parties provide, for instance, our data center, telecommunications access lines and significant computer systems and software licensing, support and maintenance services. Any interruption in these or other third-party services or deterioration in their performance could impair the quality of our service. We cannot be certain of the financial viability of all of the third parties on which we rely.

We license software from third parties, much of which is integral to our electronic trading platform and our business. We also hire contractors to assist in the development, quality assurance testing and maintenance of our electronic trading platform and other systems. Continued access to these licensors and contractors on favorable contract terms or access to alternative software and information technology contractors is important to our operations. Adverse changes in any of these relationships could have a material adverse effect on our business, financial condition and results of operations.

We attempt to negotiate favorable pricing, service, confidentiality and intellectual property ownership or licensing and other terms in our contracts with our service providers. These contracts usually have multi-year terms. However, there is no guarantee that these contracts will not terminate and that we will be able to negotiate successor agreements or agreements with alternate service providers on competitive terms. Further, the existing agreements may bind us for a period of time to terms and technology that become obsolete as our industry and our competitors advance their own operations and contracts.

Our success depends on maintaining the integrity of our electronic trading platform, systems and infrastructure; our computer systems may suffer failures, capacity constraints and business interruptions that could increase our operating costs and cause us to lose clients.

In order to be successful, we must provide reliable, real-time access to our electronic trading platform for our broker-dealer and institutional investor clients. If our electronic trading platform is hampered by slow delivery times, unreliable service or insufficient capacity, our broker-dealer and institutional investor clients may decide to stop using our platform, which would have a material adverse effect on our business, financial condition and results of operations.

As our operations grow in both size and scope, we will need to improve and upgrade our electronic trading platform and infrastructure to accommodate potential increases in order message volume and trading volume, the trading practices of new and existing clients, regulatory changes and the development of new and enhanced trading platform features, functionalities and ancillary products and services. The expansion of our electronic trading platform and infrastructure has required, and will continue to require, substantial financial, operational and technical resources. These resources will typically need to be committed well in advance of any actual increase in trading volumes and order messages. We cannot assure you that our estimates of future trading volumes and order messages will be accurate or that our systems will always be able to accommodate actual trading volumes and order messages without failure or degradation of performance. Furthermore, we use new technologies to upgrade our established systems, and the development of these new technologies also entails technical, financial and business risks. We cannot assure you that we will successfully implement new technologies or adapt our existing electronic trading platform, technology and systems to the requirements of our broker-dealer and institutional investor clients or to emerging industry standards. The inability of our electronic trading platform to accommodate increasing trading volume and order messages would also constrain our ability to expand our business.

We cannot assure you that we will not experience systems failures. Our electronic trading platform, computer and communication systems and other operations are vulnerable to damage, interruption or failure as a result of, among other things:


	•	irregular or heavy use of our electronic trading platform during peak trading times or at times of unusual market volatility;

	•	power or telecommunications failures, hardware failures or software errors;

	•	human error;

	•	computer viruses, acts of vandalism or sabotage (and resulting potential lapses in security), both internal and external;

	•	natural disasters, fires, floods or other acts of God;

	•	acts of war or terrorism or other armed hostility; and

	•	loss of support services from third parties, including those to whom we outsource aspects of our computer infrastructure critical to our business.

In the event that any of our systems, or those of our third-party providers, fail or operate slowly, it may cause any one or more of the following to occur:


	•	unanticipated disruptions in service to our clients;

	•	slower response times or delays in our clients’ trade execution;

	•	incomplete or inaccurate accounting, recording or processing of trades;

	•	financial losses and liabilities to clients;

	•	litigation or other claims against us, including formal complaints to industry regulatory organizations; and

	•	regulatory inquiries, proceedings or sanctions.

Any system failure that causes an interruption in service or decreases the responsiveness of our service, including failures caused by client error or misuse of our systems, could damage our reputation, business and brand name and lead our broker-dealer and institutional investor clients to decrease or cease their use of our electronic trading platform.

In these circumstances, our redundant systems or disaster recovery plans may not be adequate. Similarly, although many of our contracts with our service providers require them to have disaster recovery plans, we cannot be certain that these will be adequate or implemented properly. In addition, our business interruption insurance may not adequately compensate us for losses that may occur.

We also cannot assure you that we have sufficient personnel to properly respond to system problems. We internally support and maintain many of our computer systems and networks, including those underlying our electronic trading platform. Our failure to monitor or maintain these systems and networks or, if necessary, to find a replacement for this technology in a timely and cost-effective manner would have a material adverse effect on our business, financial condition and results of operations.

If our security measures are breached and unauthorized access is obtained to our electronic trading platform, broker-dealers and institutional investors may become hesitant to use, or reduce or stop their use of, our trading platform.

Our electronic trading platform involves the storage and transmission of our clients’ proprietary information. The secure transmission of confidential information over public networks is a critical element of our operations. Security breaches could expose us to a risk of loss of this information, litigation and possible liability. If our security measures are breached as a result of third-party action, employee error, malfeasance or otherwise, and, as a result, someone obtains unauthorized access to trading or other confidential information, our reputation could be damaged, our business may suffer and we could incur significant liability. Because techniques used to obtain unauthorized access or to sabotage computer systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures. If an actual, threatened or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed and could cause broker-dealers and clients to reduce or stop their use of our electronic trading platform. We may be required to expend significant resources to protect against the threat of security breaches or to alleviate problems, including reputational harm and litigation, caused by any breaches. Although we intend to continue to implement industry-standard security measures, we cannot assure you that those measures will be sufficient.

We may not be able to protect our intellectual property rights or technology effectively, which would allow competitors to duplicate or replicate our electronic trading platform. This could adversely affect our ability to compete.

Intellectual property is critical to our success and ability to compete, and if we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology. We rely primarily on a combination of patent, copyright, trademark and trade secret laws in the United States and other jurisdictions, as well as license agreements, third-party non-disclosure and other agreements and other contractual provisions and technical measures to protect our intellectual property rights. We attempt to negotiate beneficial intellectual property ownership provisions in our contracts and also require employees, consultants, advisors and collaborators to enter into confidentiality agreements in order to protect the confidentiality of our proprietary information. We have filed six patent applications covering aspects of our technologyand/or business, but can make no assurances that any such patents will be issued or, if issued, will protect our business and processes from competition. Additionally, laws and our contractual terms may not be sufficient to protect our technology from use or theft by third parties. For instance, a third party might reverse engineer or otherwise obtain and use our technology without our permission and without our knowledge, thereby infringing our rights and allowing competitors to duplicate or replicate our products. Furthermore, we cannot assure you that these protections will be adequate to prevent our competitors from independently developing technologies that are substantially equivalent or superior to our technology.

We may have legal or contractual rights that we could assert against illegal use of our intellectual property rights, but lawsuits claiming infringement or misappropriation are complex and expensive, and the outcome would not be certain. In addition, the laws of some countries in which we now or in the future provide our services may not protect software and intellectual property rights to the same extent as the laws of the United States.

Defending against intellectual property infringement or other claims could be expensive and disruptive to our business. If we are found to infringe the proprietary rights of others, we could be required to redesign our products, pay royalties or enter into license agreements with third parties.

In the technology industry, there is frequent litigation based on allegations of infringement or other violations of intellectual property rights. As the number of participants in our market increases and the number of patents and other intellectual property registrations increases, the possibility of an intellectual property claim against us grows. Although we have never been the subject of a material intellectual property dispute, we cannot assure you that a third party will not assert in the future that our technology or the manner in which we operate our business violates its intellectual property rights. From time to time, in the ordinary course of our business, we may become subject to legal proceedings and claims relating to the intellectual property rights of others, and we expect that third parties may assert intellectual property claims against us, particularly as we expand the complexity and scope of our business, the number of electronic trading platforms increases and the functionality of these platforms further overlaps. Any claims, whether with or without merit, could:


	•	be expensive and time-consuming to defend;

	•	prevent us from operating our business, or portions of our business;

	•	cause us to cease developing, licensing or using all or any part of our electronic trading platform that incorporates the challenged intellectual property;

	•	require us to redesign our products or services, which may not be feasible;

	•	result in significant monetary liability;

	•	divert management’s attention and resources; and

	•	require us to pay royalties or enter into licensing agreements in order to obtain the right to use necessary technologies, which may not be possible on commercially reasonable terms.

We cannot assure you that third parties will not assert infringement claims against us in the future with respect to our electronic trading platform or any of our other current or future products or services or that any such assertion will not require us to cease providing such services or products, try to redesign our products or services, enter into royalty arrangements, if available, or engage in litigation that could be costly to us. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

If we are unable to enter into additional marketing and strategic alliances or if our current strategic alliances are not successful, we may not maintain the current level of trading or generate increased trading on our trading platform.

From time to time, we may enter into strategic alliances that will enable us to enter new markets, provide products or services that we do not currently offer or otherwise enhance the value of our platform to our clients.

Entering into joint ventures and alliances entails risks, including:


	•	difficulties in developing and expanding the business of newly-formed joint ventures;

	•	exercising influence over the activities of joint ventures in which we do not have a controlling interest; and

	•	potential conflicts with or among our joint venture or alliance partners.

We cannot assure you that we will be able to enter into new strategic alliances on terms that are favorable to us, or at all. These arrangements, if entered into, may not generate the expected number of new clients or increased trading volume we are seeking. Unsuccessful joint ventures or alliances could have a material adverse effect on our business, financial condition and results of operations.

If we acquire or invest in other businesses, products or technologies, we may be unable to integrate them with our business, our financial performance may be impaired or we may not realize the anticipated financial and strategic goals for any such transactions.

If appropriate opportunities present themselves, we may acquire or make investments in businesses, products or technologies that we believe are strategic. We may not be able to identify, negotiate or finance any future acquisition or investment successfully. Even if we do succeed in acquiring or investing in a business, product or technology, such acquisitions and investments involve a number of risks, including:


	•	we may find that the acquired company or assets do not further our business strategy, or that we overpaid for the company or assets, or the economic conditions underlying our acquisition decision may change;

	•	we may have difficulty integrating the acquired technologies or products with our existing electronic trading platform, products and services;

	•	we may have difficulty integrating the operations and personnel of the acquired business, or retaining the key personnel of the acquired business;

	•	there may be client confusion if our services overlap with those of the acquired company;

	•	our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically or culturally diverse enterprises;

	•	we may have difficulty maintaining uniform standards, controls, procedures and policies across locations;

	•	an acquisition may result in litigation from terminated employees or third parties; and

	•	we may experience significant problems or liabilities associated with product quality, technology and legal contingencies.

These factors could have a material adverse effect on our business, financial condition, results of operations and cash flows, particularly in the case of a larger acquisition or multiple acquisitions in a short period of time. From time to time, we may enter into negotiations for acquisitions or investments that are not ultimately consummated. Such negotiations could result in significant diversion of management time, as well asout-of-pocket costs.

The consideration paid in connection with an investment or acquisition also affects our financial results. If we were to proceed with one or more significant acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash to consummate any acquisition. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options or other rights, existing stockholders may be diluted and earnings per share may decrease. In addition, acquisitions may result in the incurrence of debt, large one-time write-offs, such as of acquired in-process research and development costs, and restructuring charges. They may also result in goodwill and other intangible assets that are subject to impairment tests, which could result in future impairment charges.

We are dependent on our management team, and the loss of any key member of this team may prevent us from implementing our business plan in a timely manner.

Our success depends largely upon the continued services of our executive officers and other key personnel, particularly Richard M. McVey, Chief Executive Officer and Chairman of our Board of Directors. The terms of Mr. McVey’s employment agreement with us do not require him to continue to work for us and allow him to terminate his employment at any time, subject to certain notice requirements and forfeiture of non-vested equity options and restricted stock. Any loss or interruption of Mr. McVey’s services or that of one or more of our other executive officers or key personnel could result in our inability to manage our operations effectivelyand/or pursue our business strategy.

Because competition for our employees is intense, we may not be able to attract and retain the highly skilled employees we need to support our business.

We strive to provide high-quality services that will allow us to establish and maintain long-term relationships with our broker-dealer and institutional investor clients. Our ability to provide these services and maintain these relationships, as well as our ability to execute our business plan generally, depends in large part upon our employees. We must attract and retain highly qualified personnel. Competition for these personnel is intense, especially for software engineers with extensive experience in designing and developing software and Internet-related services, hardware engineers, technicians, product managers and senior sales executives.

The market for qualified personnel has grown more competitive in recent periods as electronic commerce has experienced growth. Domestic and international labor markets have tightened in concert with the continuing recovery in general economic conditions. Many of the companies with which we compete for experienced personnel have greater resources than we have and are longer established in the marketplace. In addition, in making employment decisions, particularly in the Internet, high-technology and financial services industries, job candidates often consider the total compensation package offered, including the value of the stock- based compensation they are to receive in connection with their employment. Significant volatility in the price of our common stock may adversely affect our ability to attract or retain key employees. The implementation of SFAS 123R relating to the expensing of stock-based compensation may discourage us from granting the size or type of stock-based compensation that job candidates may require to join our company.

We cannot assure you that we will be successful in our efforts to recruit and retain the required personnel. The failure to attract new personnel or to retain and motivate our current personnel may have a material adverse effect on our business, financial condition and results of operations.

Termination of employees may result in additional costs.

We are currently involved in arbitration claims filed against us by two former employees. We believe that both cases are without merit and we intend to vigorously defend them. However, an adverse settlement or judgment related to these or similar types of claims may have an adverse effect on our financial condition or results of operations. Regardless of the outcome of these claims, we may incur significant expense and management time dealing with such claims.

Our business is subject to increasingly extensive government and other regulation and our relationships with our broker-dealer clients may subject us to increasing regulatory scrutiny.

The financial industry is extensively regulated by many governmental agencies and self-regulatory organizations, including the SEC and the NASD. As a matter of public policy, these regulatory bodies are responsible for safeguarding the integrity of the securities and other financial markets and protecting the interests of investors in those markets. These regulatory bodies have broad powers to promulgate and interpret, investigate and sanction non-compliance with their laws, rules and regulations.

Most aspects of our broker-dealer subsidiaries are highly regulated, including:


	•	the way we deal with our clients;

	•	our capital requirements;

	•	our financial and regulatory reporting practices;

	•	required record-keeping and record retention procedures;

	•	the licensing of our employees; and

	•	the conduct of our directors, officers, employees and affiliates.

We cannot assure you that weand/or our directors, officers and employees will be able to fully comply with these laws, rules and regulations. If we fail to comply with any of these laws, rules or regulations, we may be subject to censure, fines,cease-and-desist orders, suspension of our business, suspensions of personnel or other sanctions, including revocation of our membership in the NASD and registration as a broker-dealer.

We have two major operating subsidiaries, MarketAxess Corporation and MarketAxess Europe Limited. MarketAxess Corporation and MarketAxess Europe Limited are subject to U.S. and U.K. regulations as a registered broker-dealer and as an alternative trading system, respectively, which prohibit repayment of borrowings from the Company or affiliates, paying cash dividends, making loans to the Company or affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources, without prior notification to or approval from such subsidiary’s principal regulator.

Changes in laws or regulations or in governmental policies, including the rules relating to the maintenance of specific levels of net capital applicable to our broker-dealer subsidiaries, could have a material adverse effect on our business, financial condition and results of operations. Our industry has been and is subject to continuous regulatory changes and may become subject to new regulations or changes in the interpretation or enforcement of existing regulations, which could require us to incur significant compliance costs or cause the development of affected markets to become impractical. In addition, as we expand our business into new markets, it is likely that we will be subject to additional laws, rules and regulations. We cannot predict the extent to which any future regulatory changes may adversely affect our business and operations.

Our disclosed trading system has not been subjected to regulation as an alternative trading system under Regulation ATS. A determination by the SEC to treat our trading platform as an alternative trading system subject to Regulation ATS would subject us to additional reporting obligations and other limitations on the conduct of our business, many of which could be material. Our anonymousdealer-to-dealer trading service, DealerAxess^®, is regulated as an alternative trading system subject to Regulation ATS.

As an enterprise founded and historically controlled by broker-dealer competitors, we may be subject to ongoing regulatory scrutiny of our business to a degree that is not likely to be experienced by some of our competitors. In November 2000, we received a Civil Investigative Demand from the U.S. Department of Justice in connection with the Antitrust Division’s investigation of electronic bond and other consortia trading systems. After compliance with all information requests, we received notice from the U.S. Department of Justice in 2004 that the investigation was officially closed. As the use of our electronic trading platform grows and represents a greater share of the trading volume of fixed-income securities, the risk that other regulatory investigations could commence in the future increases. Additionally, the involvement of individuals affiliated with certain of our broker-dealer clients on our Board of Directors and as stockholders may subject us to increased regulatory scrutiny of our business. At any time, the outcome of investigations and other regulatory scrutiny could lead to compulsory changes to our business model, conduct or practices, or our relationships with our broker-dealer clients, or additional governmental scrutiny or private lawsuits against us, any of which could materially harm our revenues, impair our ability to provide access to the broadest range of fixed-income securities and impact our ability to grow and compete effectively, particularly as we implement new initiatives designed to enhance our competitive position.

The activities and consequences described above may result in significant distractions to our management and could have a material adverse effect on our business, financial condition and results of operations.

We expect to continue to expand our operations outside of the United States; however, we may face special economic and regulatory challenges that we may not be able to meet.

We operate an electronic trading platform in Europe and we plan to further expand our operations throughout Europe and other regions. There are certain risks inherent in doing business in international markets, particularly in the financial services industry, which is heavily regulated in many jurisdictions outside the United States. These risks include:


	•	less developed technological infrastructures and generally higher costs, which could result in lower client acceptance of our services or clients having difficulty accessing our trading platform;


	•	difficulty in obtaining the necessary regulatory approvals for planned expansion, if at all, and the possibility that any approvals that are obtained may impose restrictions on the operation of our business;

	•	the inability to manage and coordinate the various regulatory requirements of multiple jurisdictions that are constantly evolving and subject to unexpected change;

	•	difficulties in staffing and managing foreign operations;

	•	fluctuations in exchange rates;

	•	reduced or no protection for intellectual property rights;

	•	seasonal reductions in business activity; and

	•	potentially adverse tax consequences.

Our inability to manage these risks effectively could adversely affect our business and limit our ability to expand our international operations, which could have a material adverse effect on our business, financial condition and results of operations.

We cannot predict our future capital needs or our ability to obtain additional financing if we need it.

Our business is dependent upon the availability of adequate funding and regulatory capital under applicable regulatory requirements. Historically, we have satisfied these needs primarily through equity financing from certain of our broker-dealer clients, our acquisition of Trading Edge, Inc., internally generated funds and, most recently, our initial public offering. Although we believe that our available cash resources are sufficient to meet our presently anticipated liquidity needs and capital expenditure requirements for at least the next 12 months, we may in the future need to raise additional funds to, among other things:


	•	support more rapid growth of our business;

	•	develop new or enhanced services and products;

	•	respond to competitive pressures;

	•	acquire complementary companies or technologies;

	•	enter into strategic alliances;

	•	increase the regulatory net capital necessary to support our operations; or

	•	respond to unanticipated capital requirements.

We may not be able to obtain additional financing, if needed, in amounts or on terms acceptable to us, if at all. Our existing investors, including our broker-dealer clients and their affiliates, have no obligation to make further investments in us, and we do not anticipate that they will do so. If sufficient funds are not available or are not available on terms acceptable to us, our ability to fund our expansion, take advantage of acquisition opportunities, develop or enhance our services or products, or otherwise respond to competitive pressures would be significantly limited. These limitations could have a material adverse effect on our business, financial condition and results of operations.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act, the Sarbanes-Oxley Act of 2002 and NASDAQ rules promulgated in response to the Sarbanes-Oxley Act. The requirements of these rules and regulations have increased our legal and financial compliance costs, made some activities more difficult, time-consuming or costly and may place undue strain on our systems and resources. The Securities Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls for financial reporting. In order to maintain and

improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, significant resources and management oversight are required. As a result, management’s attention may be diverted from other business concerns, which could have a material adverse effect on our business, financial condition and results of operations.

These rules and regulations could also make it more difficult for us to attract and retain qualified independent members of our Board of Directors. Additionally, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance. We may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. NASDAQ rules also require that a majority of our Board of Directors and all of certainsub-committees of the Board of Directors consist of independent directors. We cannot assure you that our Board of Directors will continue to include a majority of independent directors to comply with the requirements of these rules.

Compliance with changing laws and regulations relating to corporate governance and public disclosure has resulted, and will continue to result, in the incurrence of additional expenses associated with being a public company.

New and changing laws and regulations, including the Sarbanes-Oxley Act of 2002, impose stricter corporate governance requirements and greater disclosure obligations. They have had the effect of increasing the complexity and cost of our corporate governance compliance, diverting the time and attention of our management from revenue-generating activities to compliance activities and increasing the risk of personal liability for our board members and executive officers involved in our corporate governance process. Our efforts to comply with evolving laws and regulations has resulted in increased general and administrative expenses and increased professional fees. In addition, it may become more difficult and expensive for us to obtain director and officer liability insurance. These laws and regulations may impose obligations that will increase the legal and financial costs required to consummate a business combination and increase the time required to complete a transaction. Furthermore, in order to meet the new corporate governance and disclosure obligations, we have been taking, and will continue to take, steps to improve our controls and procedures and related corporate governance policies and procedures to address compliance issues and correct any deficiencies that we may discover.

While we believe that the procedures and policies that we have in place are effective to address the Sarbanes-Oxley Act of 2002 and other regulatory requirements, the expansion of our operations and the growth of our business may require us to modify and expand our disclosure controls and procedures and related corporate governance policies. Any unanticipated difficulties in preparing for and implementing these and other corporate governance and reporting reforms could result in material delays in compliance or significantly increase our costs. Also, there can be no assurance that we will be able to fully comply with these new laws and regulations. If we fail to prepare for and implement the reforms required by these new laws and regulations on a timely basis, our business, financial condition and results of operations could be negatively impacted, our reputation may be harmed and our stock price may be adversely affected.

We are subject to the risks of litigation and securities laws liability.

Many aspects of our business, and the businesses of our clients, involve substantial risks of liability. Dissatisfied clients may make claims regarding quality of trade execution, improperly settled trades, mismanagement or even fraud against their service providers. We and our clients may become subject to these claims as the result of failures or malfunctions of our electronic trading platform and services provided by us. We could incur significant legal expenses defending claims, even those without merit. An adverse resolution of any lawsuits or claims against us could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Our Industry

If the use of electronic trading platforms does not continue to increase, we will not be able to achieve our business objectives.

The success of our business plan depends on our ability to create an electronic trading platform for a wide range of fixed-income products. Historically, fixed-income securities markets operated through telephone communications between institutional investors and broker-dealers. The utilization of our products and services depends on the acceptance, adoption and growth of electronic means of trading securities. We cannot assure you that the growth and acceptance of electronic means of trading securities will continue.

Economic, political and market factors beyond our control could reduce demand for our services and harm our business, and our profitability could suffer.

The global financial services business is, by its nature, risky and volatile and is directly affected by many national and international factors that are beyond our control. Any one of these factors may cause a substantial decline in the U.S. and global financial services markets, resulting in reduced trading volume. These events could have a material adverse effect on our business, financial condition and results of operations. These factors include:


	•	economic and political conditions in the United States and elsewhere;

	•	adverse market conditions, including unforeseen market closures or other disruptions in trading;

	•	actual or threatened acts of war or terrorism or other armed hostilities;

	•	concerns over inflation and weakening consumer confidence levels;

	•	the availability of cash for investment by mutual funds and other wholesale and retail investors;

	•	the level and volatility of interest and foreign currency exchange rates; and

	•	legislative and regulatory changes.

Any one or more of these factors may contribute to reduced activity and prices in the securities markets generally. Our revenues and profitability are likely to decline significantly during periods of stagnant economic conditions or low trading volume in the U.S. and global financial markets.


Item 1B.	*Unresolved Staff Comments*

None.


Item 2.	*Properties*

Our corporate headquarters and principal U.S. offices are located at 140 Broadway, New York, New York, where we lease the entire 42nd floor, which is 24,000 square feet, and a portion of the 24th floor, which is 5,300 square feet. This lease expires in February 2010. In addition, we lease another 17,000 square feet at 350 Madison Avenue, New York, New York, which we currently sublet. The lease and sublease expire in April 2011. MarketAxess Europe Limited’s headquarters and principal offices are located at 71 Fenchurch Street, London, England, where we lease the entire 9th and 10th floors, which are 4,700 square feet per floor. This lease expires in November 2015.


Item 3.	*Legal Proceedings*

In January 2007, two former employees commenced arbitration proceedings against us before the National Association of Securities Dealers (“NASD”) arising out of the expiration of certain vested and unvested stock options and unvested restricted shares issued to them. The claims made by these two former employees total $4.5 million plus interest.

One former employee has alleged that we wrongfully prevented him from exercising his vested options when he sought to do so and that we wrongfully claimed that such options had expired on the previous day.

The other former employee has alleged that we wrongfully failed to accelerate the vesting of his then unvested options and restricted shares upon his termination and to waive the90-day time period within which he was required to exercise his vested options. This former employee also alleges that he is entitled to a declaration that certain provisions in our 2004 Stock Incentive Plan are invalid and unenforceable under applicable law. He further alleges that he is entitled to a bonus for the approximately five months that he worked for us during 2006.

We believe that both cases are without merit and we intend to vigorously defend them. We are required to answer, move or otherwise respond to both arbitration claims during March 2007. Based on currently available information, we believe that the likelihood of a material loss is not probable. Accordingly, no amounts have been provided in the accompanying financial statements. However, arbitration is subject to inherent uncertainties and unfavorable rulings could occur.


Item 4.	*Submission of Matters to a Vote of Security Holders*

No matters were submitted to security holders for a vote during the fourth quarter of our fiscal year ended December 31, 2006.

(1)		Commissions include commissions from transactions between institutional investor clients and broker-dealer clients as well as transactions between broker-dealer clients.

(2)		Other commissions consist primarily of commissions from the trading of emerging markets, crossover and high-yield, new issue, agency and treasury bonds as well as credit default swap indices.

(3)		Other revenues consist primarily of telecommunications line charges to broker-dealer clients, other miscellaneous revenues and, in 2002, insurance proceeds

(4)		We adopted SFAS 123R using the modified prospective transition method, which requires the application of the accounting standard as of January 1, 2006. In accordance with the modified prospective transition method, our Consolidated Financial Statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123R. Incremental stock-based compensation expense related to employee stock options recognized under SFAS 123R for the year ended December 31, 2006 was $3.2 million.

(5)		Warrant-related expense is the expense associated with the allocation of warrants to purchase shares of our common stock issuable pursuant to a warrant issued to six of our broker-dealer clients at the time they made an equity investment in us. As of December 31, 2006, 2005, 2004, 2003 and 2002, the total number of shares underlying the warrant was 2,379,396, 3,674,400, 5,007,969, 4,778,800 and 3,466,300, respectively. While the warrant was expensed each quarter, this was a non-cash expense that varied with the underlying fair market value of our common stock. The final share allocations under the warrant program occurred on March 1, 2004. Accordingly, we no longer record any expense related to this warrant.

(6)		During the year ended December 31, 2004, we reduced the valuation allowance relating to our deferred tax assets by $46.1 million, from $64.3 million to $18.1 million. Due to the fact that we had achieved multiple quarters of profitability, it became more likely than not that we would be able to utilize our net operating loss carryforwards. We also determined that it was more likely than not that all of the temporary differences relating to the deductibility of certain expenses for book and tax purposes, including the warrant-related expense, would be utilized prior to expiration. We also recognized $2.1 million in tax credits and an additional tax benefit for operating losses of $1.5 million. Without giving effect to the reduction of the valuation allowance, tax credits and the additional benefit for operating losses, our net income for the year ended December 31, 2004 would have been $7.9 million.

(7)		Includes the effect of dividends accrued on our redeemable convertible preferred stock. We have not included dilutive net income (loss) per common share for periods in which we had a net loss, as the effect would have been anti-dilutive. Upon completion of our initial public offering, all outstanding shares of redeemable convertible preferred stock and convertible preferred stock were converted into 14,484,493 shares of common stock and 4,266,310 shares of non-voting common stock.

(8)		Working capital is defined as current assets minus current liabilities. Current assets consist of Cash and cash equivalents, Short-term investments, Securities and cash provided as collateral, Accounts receivable, and Prepaid expenses. Current liabilities consist of Accrued employee compensation, Deferred revenue, and Accounts payable, accrued expenses and other liabilities.

Executive Summary

Our multi-dealer trading platform allows our institutional investor clients to simultaneously request competing, executable bids or offers from our broker-dealer clients and execute trades with the broker-dealer of their choice from among those that choose to respond. We offer our broker-dealer clients a solution that enables them to efficiently reach our institutional investor clients for the distribution and trading of bonds. In addition to U.S. high-grade corporate bonds, European high-grade corporate bonds and emerging markets bonds, including both investment-grade and non-investment grade debt, we also offer our clients the ability to trade crossover and high-yield bonds, agency bonds and credit default swap indices. Our DealerAxess^® trading service allows dealers to trade fixed-income securities with each other on our platform.

We seek to grow and diversify our revenues by capitalizing on our status as the operator of a leading platform for the electronic trading of corporate bonds and certain other types of fixed-income securities. The key elements of our strategy are:


	•	to innovate and efficiently add new functionality and product offerings to the MarketAxess platform that we believe will help to increase our market share with existing clients, as well as expand our client base;

	•	to leverage our technology, as well as our strong broker-dealer and institutional investor relationships, to deploy our electronic trading platform into additional product segments within the fixed-income securities markets;

	•	to leverage our technology and client relationships to deploy our electronic trading platform into new client segments;

	•	to continue building our existing service offerings so that our electronic trading platform is fully integrated into the workflow of our broker-dealer and institutional investor clients and to continue to add functionality


		to allow our clients to achieve a fully automatedend-to-end straight-through processing solution (automation from trade initiation to settlement);


	•	to add new content and analytical capabilities to Corporate BondTicker^tm in order to improve the value of the information we provide to our clients; and

	•	to continue to supplement our internal growth by entering into strategic alliances, or acquiring businesses or technologies that will enable us to enter new markets, provide new products or services, or otherwise enhance the value of our platform to our clients.

History

MarketAxess was formed in April 2000, and pilot trading on our fully disclosed multi-dealer platform began in October 2000. We launched trading on our electronic platform in January 2001 with eight broker- dealer clients. Since that time, our broker-dealer clients have grown to include 25 leading securities firms. Our broker-dealer clients currently are: ABN AMRO, Banc of America Securities, Barclays PLC, Bear Stearns, BNP Paribas, Citigroup Global Markets, Credit Suisse, Deutsche Bank Securities, Dresdner Bank AG, DZ Bank AG, FTN Financial, Goldman Sachs, HSBC, ING Financial Markets, JPMorgan, Jefferies and Company, Lehman Brothers, Merrill Lynch, Morgan Stanley, RBC Capital Markets, The Royal Bank of Scotland, Santander Investment Securities, SG Corporate & Investment Banking, UBS and Wachovia Securities.

In March 2001, we acquired Trading Edge, Inc. (“Trading Edge”), the operator of an anonymous trading platform for U.S. corporate bonds, convertible bonds, municipal bonds and emerging markets bonds. In 2001, we decided to terminate the anonymous convertible and municipal bond trading platforms and currently offer U.S. corporate bond and emerging markets bond trading on a fully disclosed basis only. The technology platform developed by Trading Edge and obtained by us through the acquisition is now the core of our product offerings.

In August 2001, one of our U.K. subsidiaries, MarketAxess Europe Limited, began operations with secondary electronic trading in U.S. dollar-denominated and Euro-denominated corporate bonds.

In February 2002, we reorganized into MarketAxess Holdings Inc., a holding company that operates primarily through two operating subsidiaries, MarketAxess Corporation and MarketAxess Europe Limited. MarketAxess Corporation is registered as a broker-dealer, and MarketAxess Europe Limited is regulated as an alternative trading system, with applicable market regulators in the U.S. and the U.K., respectively. In May 2003, we incorporated a Canadian subsidiary, MarketAxess Canada Limited, which has applied for registration under the Securities Act in Ontario and is in the process of seeking approval for membership with the Investment Dealers Association of Canada.

We launched our information service, Corporate BondTicker, in July 2002. Corporate BondTicker combines NASD TRACE data with MarketAxess data and analytical tools to provide trading professionals, research firms, rating and news agencies, and other market participants with a comprehensive set of corporate bond information.

On November 4, 2004, we completed the initial public offering of our common stock. Specifically, 5,750,000 shares of common stock, including an aggregate of 750,000 shares of common stock covered by an over-allotment option granted by us to the underwriters, were sold at a price to the public of $11.00 per share. The aggregate proceeds to us from the offering were $63.2 million before deducting $4.4 million in underwriting discounts and commissions and an estimated $4.9 million in other expenses incurred in connection with the offering.

In September 2005, we launched electronic credit default swap trading on our platform.

In June 2006, we introduced DealerAxess^®, which allows broker-dealer clients to transact U.S. corporate, emerging markets and high-yield bond trades on our platform with other broker-dealer clients. MarketAxess Corporation acts as intermediary in these transactions by serving as counterparty to the two broker-dealer clients involved.

Critical Factors Affecting Our Industry and Our Company

Economic, Political and Market Factors

The global fixed-income securities industry is risky and volatile and is directly affected by a number of economic, political and market factors that may result in declining trading volume. These factors could have a material adverse effect on our business, financial condition and results of operations. These factors include:


	•	the current interest rate environment, including the volatility of interest rates and investors’ forecasts of future interest rates;

	•	economic and political conditions in the United States, Europe and elsewhere;

	•	the availability of cash for investment by mutual funds and other institutional and retail investors;

	•	the volume of new fixed-income securities being brought to the market;

	•	investors’ assessment of the level of risk attributable to the issuers of corporate bonds;

	•	adverse market conditions, including unforeseen market closures or other disruptions in trading;

	•	concerns over inflation and weakening consumer confidence levels;

	•	the level and volatility of foreign currency exchange rates; and

	•	legislative and regulatory changes.

Any one or more of these factors may contribute to reduced trading activity in the fixed-income securities markets generally. Our revenues and profitability are likely to decline during periods of stagnant economic conditions or low trading volume in the U.S. and global fixed-income securities markets.

Competitive Landscape

The global fixed-income securities industry generally, and the electronic financial services markets in which we engage in particular, are highly competitive, and we expect competition to intensify in the future. We will continue to compete with bond trading conducted directly between broker-dealers and their institutional investor clients over the telephone or electronically. In addition, our current and prospective competitors are numerous and include:


	•	other multi-dealer trading companies;

	•	market data and information vendors;

	•	securities and futures exchanges;

	•	inter-dealer brokerage firms;

	•	electronic communications networks;

	•	technology, software, information and media or other companies that have existing commercial relationships with broker-dealers or institutional investors; and

	•	other electronic marketplaces that are not currently in the securities business.

In general, we compete on the basis of a number of key factors, including:


	•	the liquidity provided on our platform;

	•	the magnitude and frequency of price improvement enabled by our platform;

	•	the quality and speed of execution;


	•	total transaction costs;

	•	technology capabilities, including the ease of use of our trading platform; and

	•	the range of our products and services.

We believe that we compete favorably with respect to these factors. Our trading volume and client acceptance have grown significantly over the past five years and we continue to proactively build technology solutions that serve the needs of the credit markets.

Many of our current and potential competitors are more established and substantially larger than we are, and have a substantially greater market presence, as well as greater financial, engineering, technical, marketing and other resources. These competitors may aggressively reduce their pricing to enter into market segments in which we have a leadership position today, potentially subsidizing any losses with profits from trading in other securities. In addition, many of our competitors offer a wide range of services, have broader name recognition and have larger customer bases. Some of them may be able to respond more quickly to new or evolving opportunities, technologies and customer requirements than we can and may be able to undertake more extensive promotional activities.

Any combination of our competitors or our current broker-dealer clients may enter into joint ventures or consortia to provide services similar to those provided by us. Others may acquire the capabilities necessary to compete with us through acquisitions. Significant consolidation has occurred in our industry and these firms, as well as others that may undertake such consolidation in the future, are potential competitors of ours.

Regulatory Environment

Our industry has been and is subject to continuous regulatory changes and may become subject to new regulations or changes in the interpretation or enforcement of existing regulations, which could require us to incur significant costs.

Our U.S. subsidiary, MarketAxess Corporation, is a registered broker-dealer with the SEC and is a member of the NASD. Our U.K. subsidiary, MarketAxess Europe Limited, is registered as an Alternative Trading System dealer with the FSA in the U.K. Both U.S. and U.K. regulations prohibit repayment of borrowings from these subsidiaries or their affiliates, paying cash dividends, making loans to us or our affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources, without prior notification to or approval from such regulated entity’s principal regulator. MarketAxess Canada Limited, a Canadian subsidiary that we incorporated in May 2003, has applied for registration as an Alternative Trading System dealer under the Securities Act of Ontario and is in the process of seeking approval for membership with the Investment Dealers Association of Canada.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act, the Sarbanes-Oxley Act of 2002 and NASDAQ rules promulgated in response to the Sarbanes-Oxley Act. The requirements of these rules and regulations have increased our legal and financial compliance costs, made some activities more difficult, time-consuming or costly and may also place undue strain on our systems and resources. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, significant resources and management oversight are required.

Rapid Technological Changes

industry standards and practices emerge, our existing technology, systems and electronic trading platform may become obsolete or our existing business may be harmed. Our future success will depend on our ability to:


	•	enhance our existing products and services;

	•	developand/or license new products and technologies that address the increasingly sophisticated and varied needs of our broker-dealer and institutional investor clients and prospective clients; and

	•	respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis.

Trends in Our Business

The majority of our revenues are derived from commissions for transactions executed on our platform between our institutional investor and broker-dealer clients. We believe that there are five key variables that impact the notional value of such transactions on our platform and the amount of commissions earned by us:


	•	the number of institutional investor clients that participate on the platform and their willingness to originate transactions through the platform;

	•	the number of broker-dealer clients on the platform and the competitiveness of the prices they provide to the institutional investor clients;

	•	the number of markets for which we make trading available to our clients;

	•	the overall level of activity in these markets; and

	•	the level of commissions that we collect for trades executed through the platform.

We believe that overall corporate bond market trading volume is affected by various factors including the absolute levels of interest rates, the direction of interest rate movements, the level of new issues of corporate bonds and the volatility of corporate bond spreads versus U.S. Treasury securities. Because a significant percentage of our revenue is tied directly to the volume of securities traded on our platform, it is likely that a general decline in trading volumes, regardless of the cause of such decline, would reduce our revenues and have a significant negative impact on profitability.

We have historically earned a substantial portion of our commissions and overall revenues from broker-dealer clients that are (or whose affiliates are) our stockholders. The percentage of our revenues derived from our broker-clients that are also our stockholders has been declining. For the year ended December 31, 2006, the percentage decreased to 46.0% from 49.7% for the year ended December 31, 2005. Affiliates of most of our broker-dealer clients are also among our institutional investor clients. A table detailing the amount of revenues generated by the nine broker-dealer clients that were also stockholders as of January 1, 2006 (ABN AMRO, Banc of America Securities, Bear Stearns, BNP Paribas, Credit Suisse, Deutsche Bank Securities, JPMorgan, Lehman Brothers and

UBS), and their respective affiliates, as well as the corresponding percentage of total revenues, is provided below for the years ended December 31, 2006, 2005 and 2004:

Commission Revenue Trends

Commissions are generally calculated as a percentage of the notional dollar volume of bonds traded on our platform and vary based on the type, size, yield and maturity of the bond traded. The commission rates are based on a number of factors, including fees charged by inter-dealer brokers in the respective markets, average bid-offer spreads in the products we offer, transaction costs through alternative channels including the telephone and the trading volume executed through our platform by the broker-dealer completing the trade. Under our transaction fee plans, bonds that are more actively traded or that have shorter maturities are generally charged lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions.

U.S. High-Grade Corporate Bonds On June 1, 2005, we introduced a new fee plan primarily for secondary market transactions in U.S. high-grade corporate bonds executed on our institutional client to multi-dealer electronic trading platform. Most of our U.S. high-grade broker-dealer clients signed new two-year agreements in 2005. The agreements incorporate higher fixed monthly fees and lower variable fees for our broker-dealer clients than the previous U.S. high-grade corporate transaction fee plans and incorporate volume incentives to our broker-dealer clients that are designed to increase the volume of transactions effected on our platform. Under the fee plan, we electronically add the variable fee to the spread quoted by the broker-dealer client but do not charge for inquiries that an institutional investor client sends to a single broker-dealer client. The combination of higher fixed and lower variable fees in the plan results in higher revenue to us at lower volume levels but will limit revenue growth in the future for U.S. high-grade corporate bond trading as volume levels increase. For trades on our DealerAxess^®dealer-to-dealer electronic trading platform, we charge a fee to the broker-dealer client involved in the transaction that is based on the size of the transaction and the maturity of the bond traded. Monthly minimum fees apply to certain dealers participating on the DealerAxess^® platform in their first year of trading, which are due to expire in July 2007.

European High-Grade Corporate Bonds For European high-grade corporate bond trades, broker-dealer transaction fees vary based on the type of bond traded. Different fee schedules apply to fixed rate and floating rate bonds. Within the schedule for fixed rate bonds, the fee varies depending on whether the bond is a corporate or a sovereign issue. For corporate bonds, the fee also varies depending on the maturity of the issue. This fee schedule

applies a tiered fee structure, which reduces the fee per trade upon the attainment of certain specified amounts of monthly commissions generated by a particular broker-dealer and does not carry a fixed monthly fee or fee cap.

Other Commissions Commissions for other bond trades generally vary based on the type and the maturity of the bond traded. Factors that we consider when setting commission rates include those charged by inter-dealer brokers in the respective markets, average bid-offer spreads in the products we serve and transaction costs through alternative channels including the telephone. For credit default swap index trades we charge commissions to both broker-dealer and institutional investor clients calculated as a percentage of the notional volume of transactions traded. Broker-dealer clients are able to select between standard fee schedules that contain monthly minimum commissions and, in some cases, monthly fee caps.

We anticipate that some reduction in average fees per million may occur in the future. Consequently, past trends in commissions are not necessarily indicative of future commissions.

Other Revenue Trends

In addition to the commissions discussed above, we earn revenue from certain fees paid by institutional investor and broker-dealer clients, from license fees and from income on investments.

Information and User Access Fees We charge information services fees for Corporate BondTicker to our broker-dealer clients, institutional investor clients and data-only subscribers. The information services fee is a flat monthly fee, based on the level of service. We also generate information services fees from the sale of bulk data to certain institutional investor clients and data-only subscribers. Institutional investor clients trading U.S. high-grade corporate bonds are charged a monthly user access fee for the use of our platform. The fee, billed quarterly, is charged to the client based on the number of the client’s users. To encourage institutional investor clients to execute trades on our U.S. high-grade corporate bond platform, we reduce these information and user access fees for such clients once minimum quarterly trading volumes are attained.

License Fees License fees consist of fees received from broker-dealer clients for access to our trading platform through a non-exclusive and non-transferable license. Broker-dealer clients, other than those that made equity investments in the Company, typically pay an initial license fee, which is due and payable upon execution of the broker-dealer agreement. The initial license fee varies by agreement and at a minimum is generally intended to cover the initialset-up costs incurred to enable a broker-dealer to begin using our electronic trading platform. The license fee is recognized in the first three months of the agreement in the estimated amount of theset-up costs that we incur and the remaining amount is amortized over the initial term of the agreement, which is generally three years. We anticipate that license fees will be a less material source of revenues for us on a going-forward basis.

Investment Income Investment income consists of income earned on our investments. In November 2006, we commenced a $40 million share repurchase program. Investment income will decline as we use our cash to purchase our common stock under the share repurchase program.

Other Other revenues consist of telecommunications line charges to broker-dealer clients and other miscellaneous revenues.

Expense Trends

In the normal course of business, we incur the following expenses:

Employee Compensation and Benefits Employee compensation and benefits is our most significant expense and includes employee salaries, stock compensation costs, other incentive compensation, employee benefits and payroll taxes. Effective January 1, 2006, we adopted SFAS 123R, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees based on estimated fair values.

Depreciation and Amortization Depreciation and amortization expense results from the depreciation of fixed assets, which consist of computer hardware, furniture and fixtures, and the amortization of software, capitalized software development costs and leasehold improvements. We depreciate our fixed assets and amortize our capitalized software development costs on a straight-line basis over a three-year period. We amortize leasehold

improvements on a straight-line basis over the lesser of the life of the improvement or the remaining term of the lease.

Technology and Communications Technology and communications expense consists primarily of costs relating to maintenance on software and hardware, our internal network connections, data center hosting costs and data feeds provided by outside vendors or service providers. The majority of our broker-dealer clients have dedicated high-speed communication lines to our network in order to provide fast data transfer. We charge our broker-dealer clients a monthly fee for these connections, which is recovered against the relevant expenses we incur.

Professional and Consulting Fees Professional and consulting fees consist primarily of accounting fees, legal fees and fees paid to information technology and non-information technology consultants for services provided for the maintenance of our trading platform and information services products.

Warrant-related expense Warrant-related expense is the expense associated with the allocation of shares of our common stock issuable pursuant to warrants issued to six of our broker-dealer clients at the time they made an equity investment in us. The warrant program was put in place in April 2000 and was designed to motivate broker-dealers to trade on our platform. The final share allocations under the warrant program occurred on March 1, 2004. Accordingly, we no longer record any expense related to this program.

Marketing and Advertising Marketing and advertising expense consists primarily of print and other advertising expenses we incur to promote our products and services. This expense also includes costs associated with attending or exhibiting at industry-sponsored seminars, conferences and conventions, and travel and entertainment expenses incurred by our sales force to promote our trading platform and information services.

Moneyline Revenue Share Moneyline revenue share expense consists of expenses incurred pursuant to our agreement with Moneyline Telerate (“Moneyline”), formerly an independent technology and data company, which assisted us in the development of our U.S. high-grade corporate bond and European trading platforms. Pursuant to the agreement, a revenue share was paid quarterly to Moneyline based on a percentage of revenues generated on our U.S. high-grade corporate bond and European trading platforms, after deduction of identified development costs. In the first quarter of 2005, we ceased using the Moneyline technology and have therefore incurred no revenue share expense since that date.

General and Administrative General and administrative expense consists primarily of occupancy and utilities, general travel and entertainment, board of directors expenses, charitable contributions, provision for doubtful accounts, and various state franchise and U.K. value-added taxes.

We anticipate expense growth in the future, primarily due to investment in new products, notably in employee compensation and benefits, professional and consulting fees, and general and administrative expense, but we believe that operating leverage can be achieved by increasing volumes in existing products and adding new products without substantial additions to our infrastructure.

Critical Accounting Policies

This Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States, also referred to as U.S. GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of income and expenses during the reporting periods. We base our estimates and judgments on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates under varying assumptions or conditions. Note 2 of the Notes to our Consolidated Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of our Consolidated Financial Statements.

Use of Estimates

On an ongoing basis, management evaluates its estimates and judgments, particularly as they relate to accounting policies that management believes are critical. That is, these accounting policies are most important to

the portrayal of our financial condition and results of operations and they require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Allowance for Doubtful Accounts

We continually monitor collections and payments from our customers and maintain an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified. Additions to the allowance for doubtful accounts are charged to Bad debt expense, which is included in General and administrative expense in our Consolidated Statements of Operations.

Software Development Costs

In accordance with Statement of PositionNo. 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,” we capitalize certain costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. We capitalize employee compensation and related benefits and third party consulting costs incurred during the preliminary software project stage. Once the product is ready for its intended use, such costs are amortized on a straight-line basis over three years. We review the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Revenue Recognition

The majority of our revenues are derived from commissions for trades executed on its platform that are billed to our broker-dealer clients on a monthly basis. Commissions are generally calculated as a percentage of the notional dollar volume of bonds traded on the platform and vary based on the type and maturity of the bond traded. Under the our transaction fee plans, bonds that are more actively traded or that have shorter maturities are generally charged lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions.

We also derive revenues from information and user access fees, license fees, investment income and other income.

We enter into agreements with our broker-dealer clients pursuant to which we provide access to our platform through a non-exclusive and non-transferable license. Broker-dealer clients, other than those that previously made equity investments in us, generally pay an initial license fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial license fee varies by agreement and at a minimum is intended to cover the initialset-up costs incurred to enable a broker-dealer to begin using our electronic trading platform. Revenue is recognized in the first three months of the agreement in the estimated amount of theset-up costs incurred (50% in the first month, 40% in the second month and 10% in the third month), and the remaining amount is deferred and recognized ratably over the initial term of the agreement, which is generally three years. We anticipate that license fees will be a less material source of revenues on a going-forward basis.

Stock-Based Employee Compensation

Prior to January 1, 2006 we have accounted for stock-based employee compensation plans in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), as permitted by SFAS No. 123. In accordance with APB 25, compensation expense is recognized for stock awards that have intrinsic value on the date of grant. Unearned compensation is amortized and charged to income over the vesting schedule. Our employee option grants usually vest over a three-year period from the date of issuance.

Effective January 1, 2006, we adopted SFAS 123R, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees based on estimated fair values. In accordance with SFAS 123R, non-employee members of the Board of Directors are treated as employees.

SFAS 123R supersedes our previous accounting under APB 25 for periods beginning in fiscal 2006. In March 2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to SFAS 123R. We have applied the provisions of SAB 107 in our adoption of SFAS 123R.

We adopted SFAS 123R using the modified prospective transition method, which requires the application of the accounting standard as of January 1, 2006. In accordance with the modified prospective transition method, our Consolidated Financial Statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123R.

Income Taxes

Income taxes are accounted for using the asset and liability method in accordance with SFAS No. 109, “Accounting for Income Taxes” (“SFAS 109”). Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized against deferred tax assets if it is more likely than not that such assets will not be realized in future years.

Segment Results

As an electronic, multi-dealer to client platform for trading fixed-income securities, our operations constitute a single business segment pursuant to SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” Because of the highly integrated nature of the financial markets in which we compete and the integration of our worldwide business activities, we believe that results by geographic region, products or types of clients are not necessarily meaningful in understanding our business.

Stock Repurchase Program

On October 26, 2006, our Board of Directors authorized a stock repurchase program for up to $40 million of the our common stock. We intend to repurchase the shares in the open market or privately negotiated transactions, at times and prices considered appropriate by us. Shares repurchased under the program will be held in treasury for future use. As of December 31, 2006, we had repurchased 190,500 shares at a purchase price of $2.7 million. Through March 9, 2007, a total of 1,475,756 shares had been repurchased at a cost of $19.4 million.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

Overview

Total revenues increased by $4.8 million or 6.1% to $83.3 million for the year ended December 31, 2006 from $78.6 million for the year ended December 31, 2005. This increase in total revenues was primarily due to increases in total commissions of $4.5 million, investment income of $1.4 million and information and user access fees of $1.0 million, offset in part by a decrease of $2.1 million in license fees.

Total expenses increased by $7.7 million or 11.5% to $74.7 million for the year ended December 31, 2006 from $67.0 million for the year ended December 31, 2005. This increase was primarily due to increases of $6.6 million in employee compensation and benefits, $1.7 million in general and administrative expense, $1.1 million in depreciation and amortization and $0.3 million in technology and communications. These increases were offset by decreases in professional and consulting fees of $1.3 million and in marketing and advertising of $0.8 million. Excluding the impact of the incremental non-cash SFAS 123R stock option expense of $3.2 million, total expenses for the year ended December 31, 2006 increased by $4.5 million or 6.7%, to $71.5 million from $67.0 million for the year ended December 31, 2005.

For the year ended December 31, 2006, Income before taxes, which includes the incremental non-cash impact of SFAS 123R stock option expense, decreased by $3.0 million or 25.6% to $8.6 million compared to Income before taxes of $11.6 million for the year ended December 31, 2005. Net income decreased by $2.7 million or 33.4% to $5.4 million compared to Net income of $8.1 million for the year ended December 31, 2005.

Commissions. Total commissions increased by $4.5 million or 6.7% to $71.4 million for the year ended December 31, 2006 from $66.9 million for 2005. The following table shows the extent to which the increase in commissions for the year ended December 31, 2006 was attributable to transaction volumes, fixed monthly distribution and DealerAxess^® minimum fees as well as the average level of variable transaction fees:

European high-grade	$	175	$	192
Other	$	147	$	150
All Products	$	210	$	224

The U.S. high-grade average fee per million is calculated for each period presented using both the variable transaction fees and the fixed monthly fees paid by our broker-dealer clients.

The average U.S. high-grade fee per million decreased due to the introduction in June 2005 of our new fee plan, which has higher fixed monthly distribution fees and lower transaction fees, resulting in lower average fees per million at higher trading volumes, as well as the shorter maturity of trades executed on the platform. This has been partially offset by the introduction of bond trading between broker-dealer clients through our DealerAxess^® product in June 2006. The fixed monthly U.S. high-grade fixed distribution fees and the DealerAxess^® monthly minimum fees were $32.6 million for the year ended December 31, 2006, compared to $24.6 million for the year ended December 31, 2005.

The decrease in the average European high-grade fee per million from 2005 to 2006 resulted from higher trading volumes in floating-rate notes, which have lower fees per million. The decrease in the average Other fees per million resulted primarily from a change in the mix of business.

Information and User Access Fees. Information and user access fees increased by $1.0 million or 23.5% to $5.5 million for the year ended December 31, 2006 from $4.4 million for the year ended December 31, 2005. This increase was primarily due to an increase in the number of subscribers to our Corporate BondTicker service from 2,942 for the year ended December 31, 2005 to 4,629 for the year ended December 31, 2006.

License Fees. License fees decreased by $2.1 million or 71.0% to $0.9 million for the year ended December 31, 2006 from $3.0 million for the year ended December 31, 2005. This decrease was attributable to a decline in the amortization of previously received license fees. We anticipate that license fees will be a less material source of revenues for us on a going-forward basis.

Investment Income. Investment income increased by $1.4 million or 45.4% to $4.6 million for the year ended December 31, 2006 from $3.2 million for the year ended December��31, 2005. This increase was primarily due to higher Cash and cash equivalents and Securitiesavailable-for-sale balances and a rise in interest rates during the year ended December 31, 2006 as compared to the year ended December 31, 2005.

Other. Other revenues decreased by $0.1 million or 10.5% to $0.9 million for the year ended December 31, 2006 from $1.1 million for the comparable period in 2005.

Employee Compensation and Benefits. Employee compensation and benefits increased by $6.6 million or 18.7% to $42.1 million for the year ended December 31, 2006 from $35.4 million for the year ended December 31 2005. This increase was primarily attributable to incremental stock option compensation costs of $3.2 million due to

the adoption of SFAS 123R effective January 1, 2006, higher salary expense of $2.0 million, employee severance costs of $1.7 million and other stock compensation costs of $0.6 million, offset by a reduction in employee benefits and payroll taxes of $0.5 million and lower incentive compensation costs of $0.4 million. The total number of employees decreased to 176 as of December 31, 2006 from 182 as of December 31, 2005. As a percentage of total revenues, employee compensation and benefits expense increased to 50.5% for the year ended December 31, 2006 from 45.1% for the year ended December 31, 2005.

Depreciation and Amortization. Depreciation and amortization expense increased by $1.1 million or 19.1% to $6.7 million for the year ended December 31, 2006 from $5.6 million for the year ended December 31, 2005. This increase was attributable to increased amortization of capitalized software development costs for our credit default swap and DealerAxessproducts. For the year ended December 31, 2006, we capitalized $4.1 million of software development costs and $2.7 million of computer and related equipment purchases.

Technology and Communications. Technology and communications expense increased by $0.3 million or 4.1% to $7.7 million for the year ended December 31, 2006 from $7.4 million for the year ended December 31, 2005. This increase was attributable to increased cost relating to the purchase of market data.

Professional and Consulting Fees. Professional and consulting fees decreased by $1.3 million or 13.7% to $8.1 million for the year ended December 31, 2006 from $9.4 million for the year ended December 31, 2005. This decrease was primarily due to $0.9 million in recruiting fees and $0.8 million in information technology consulting costs.

Marketing and Advertising. Marketing and advertising expense decreased by $0.8 million or 31.5% to $1.8 million for the year ended December 31, 2006 from $2.6 million for the year ended December 31, 2005. This decrease was primarily due to a reduction in advertising expenditures of $0.7 million.

General and Administrative. General and administrative expense increased by $1.7 million or 26.3% to $8.4 million for the year ended December 31, 2006 from $6.6 million for the comparable period in 2005. This increase was primarily due to increases in franchise and sales taxes of $0.7 million, occupancy costs of $0.6 million, provision for bad debts of $0.2 million and $0.2 million in foreign currency translation losses.

Provision for Income Tax

For the year ended December 31, 2006, we recorded an income tax provision of $3.2 million. The provision consists principally of $1.8 million in federal taxes, $1.1 million in state and local taxes and $0.3 million in foreign taxes. For the year ended December 31, 2005, we recorded an income tax provision of $3.4 million. The provision consists principally of $1.6 million in federal taxes, $1.0 million in state and local taxes and $0.8 million in foreign taxes. For the years ended December 31, 2006 and 2005, with the exception of the payment of certain state and local taxes, the provision for income taxes was a non-cash expense since we had available net operating loss carryforwards and tax credits to offset the cash payment of taxes.

Our consolidated effective tax rate for the year ended December 31, 2006 was 37.0% and for the year ended December 31, 2005 was 29.6%. The 2005 tax provision included a $2.9 million reduction in our valuation allowance against the deferred tax asset. Our consolidated effective tax rate can vary from period to period depending on, among other factors, the geographic and business mix of our earnings.

As of December 31, 2006, we had net operating loss and tax credit carryforwards for income tax purposes of $101.6 million. We have recorded a valuation allowance of $14.8 million against the gross deferred tax assets of $56.6 million arising from the net operating loss carryforwards and temporary differences relating to the deductibility of certain expenses for book and tax purposes. This valuation allowance was deemed appropriate due to available evidence indicating that some of the deferred tax assets might not be realized in future years.

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

Overview

Total revenues increased by $2.8 million or 3.6% to $78.6 million for the year ended December 31, 2005 from $75.8 million for the year ended December 31, 2004. This increase in total revenues was primarily due to an increase in interest income of $2.3 million and information and user access fees of $1.7 million, offset in part by a decrease of $1.3 million in total commissions.

Total expenses increased by $8.5 million or 14.6% to $67.0 million for the year ended December 31, 2005 from $58.5 million for the comparable period in 2004. This increase was primarily due to increases of $4.4 million in professional and consulting fees, $2.4 million in general and administrative expense, $2.3 million in employee compensation and benefits, $2.0 million in technology and communications, and $1.1 million in depreciation and amortization expense, offset by decreases in warrant-related expense and Moneyline revenue share, in each case compared to the comparable period in 2004.

Income before taxes decreased by $5.8 million to $11.6 million compared to Income before taxes of $17.3 million for the year ended December 31, 2004. Net income decreased by $49.4 million to $8.1 million compared to Net income of $57.6 million for the year ended December 31, 2004. This decrease was primarily due to a net income tax benefit of $40.3 million that was recorded for the year ended December 31, 2004 due to the reduction of the valuation allowance against our deferred tax assets.

During the year ended December 31, 2005, we reduced the valuation allowance against the deferred tax assets by $2.9 million to $15.2 million based on management’s assessment of the factors impacting the valuation allowance previously recorded. In addition, we adjusted the income tax rate used for recording the deferred tax assets, resulting in a decrease in the deferred tax assets and an increase in tax expense of $1.8 million. Without giving effect to the adjustment to the income tax rate used for recognizing the deferred tax assets and the reduction in the valuation allowance against the deferred tax assets, our net income for the year ended December 31, 2005 would have been $7.0 million.

Commissions. Total commissions decreased by $1.3 million or 1.8% to $66.9 million for the year ended December 31, 2005 from $68.2 million for the comparable period in 2004. The following table shows the extent to which the decrease in commissions for the year ended December 31, 2005 was attributable to transaction volumes, fixed monthly distribution fees and the average level of variable transaction fees:

Our average fees per million traded for the years ended December 31, 2005 and 2004 were as follows:


	Year Ended December 31,
	2005		2004

Average Fee Per Million Traded
U.S. high-grade	$	257	$	248
European high-grade	$	192	$	198
Other	$	150	$	199
All Products	$	224	$	229

The U.S. high-grade average fee per million is calculated for each period presented using both the variable transaction fees and the fixed monthly fees paid by our broker-dealer clients.

The average U.S. high-grade fee per million increased due to the introduction in June 2005 of our new fee plan, which has higher fixed monthly distribution fees. The fixed monthly U.S. high-grade fixed distribution fees were $24.6 million for the year ended December 31, 2005 compared to $18.5 million for the year ended December 31, 2004.

The decrease in the average European high-grade and Other fees per million resulted primarily from a change in the mix of business.

Information and User Access Fees. Information and user access fees increased by $1.7 million or 63.5% to $4.4 million for the year ended December 31, 2005 from $2.7 million for the year ended December 31, 2004. This increase was primarily due to an increase in the number of subscribers to our Corporate BondTicker service.

License Fees. License fees decreased by $0.2 million or 4.9% to $3.0 million for the year ended December 31, 2005 from $3.1 million for the year ended December 31, 2004. This decrease was due to the addition of three new broker-dealer clients in the year ended December 31, 2005 compared to four new broker-dealer clients added in the year ended December 31, 2004.

Investment Income. Interest income increased by $2.3 million or 258.3% to $3.2 million for the year ended December 31, 2005 from $0.9 million for the comparable period in 2004. This increase was primarily due to higher Cash and cash equivalents and Securitiesavailable-for-sale balances during the year ended December 31, 2005 as compared to the year ended December 31, 2004.

Other. Other revenues increased by $0.2 million or 19.4% to $1.1 million for the year ended December 31, 2005 from $0.9 million for the comparable period in 2004. This increase was primarily due to a financial statement reclassification to recognize as revenue the gross telecommunication line fees paid by broker-dealer clients.

Expenses

Our expenses and percentage of revenues for the years ended December 31, 2005 and 2004, and the resulting dollar and percentage changes, are as follows:

Total expenses	$	66,999			85.3	%		58,481		77.1	%	$	8,518			14.6	%

Employee Compensation and Benefits. Employee compensation and benefits increased by $2.3 million or 6.9% to $35.4 million for the year ended December 31, 2005 from $33.1 million for the year ended December 31 2004. The total number of employees increased to 182 as of December 31, 2005 from 172 as of December 31, 2004. This increase was primarily due to the addition of new employees to support our growth (including the development of credit derivatives trading services) and higher payroll tax contributions relating to employee stock options for staff of MarketAxess Europe, higher staff benefits and lower capitalization of technology development compensation. As a percentage of total revenues, employee compensation and benefits expense increased to 45.1% for the year ended December 31, 2005 from 43.7% for the year ended December 31, 2004.

Depreciation and Amortization. Depreciation and amortization expense increased by $2.2 million or 62.9% to $5.6 million for the year ended December 31, 2005 from $3.5 million for the year ended December 31, 2004. For the year ended December 31, 2005, we capitalized $3.4 million of software development costs and $1.4 million of computer and related equipment purchases. During 2004, we purchased $2.8 million of computer and related equipment for our new disaster recovery facility, which went into production in May 2005, causing our depreciation expense to increase in 2005. In November 2004, we determined that our trading platform software developed by us with input from Moneyline, a stockholder, would be retired by March 31, 2005. Therefore, we accelerated depreciation of this software.

Technology and Communications. Technology and communications expense increased by $1.0 million or 15.6% to $7.4 million for the year ended December 31, 2005 from $6.4 million for the year ended December 31, 2004. This increase was attributable to increased costs relating to the purchase of market data, production telecommunications and software maintenance.

Professional and Consulting Fees. Professional and consulting fees increased by $4.4 million or 90.6% to $9.4 million for the year ended December 31, 2005 from $4.9 million for the year ended December 31, 2004. This increase was primarily due to additional audit and tax, legal, insurance and investor relations expenses associated with being a public company, and increased consulting and recruiting fees.

Marketing and Advertising. Marketing and advertising expense increased by $51 thousand or 2.0% to $2.6 million for the year ended December 31, 2005 from $2.5 million for the year ended December 31, 2004. This increase was primarily due to expenses we incurred for print and other advertising used to promote our electronic trading platform.

Moneyline Revenue Share. Moneyline revenue share expense decreased by $1.3 million or 104.0% to a benefit of $50 thousand from $1.2 million for the year ended December 31, 2005 due to termination of the Moneyline revenue share agreement and reversal of a prior period over-accrual in the first quarter of 2005.

General and Administrative. General and administrative expense increased by $2.4 million or 55.2% to $6.6 million for the year ended December 31, 2005 from $4.3 million for the comparable period in 2004. This increase was due to a number of factors, including increases in rent, board of directors’ costs, travel and entertainment, value-added tax and charitable contributions.

Provision for Income Tax

For the year ended December 31, 2005, we recorded an income tax provision of $3.4 million. The provision consisted principally of $1.6 million in federal taxes, $1.0 million in state and local taxes and $0.8 million in foreign taxes. With the exception of the payment of certain state and local taxes, the provision for income taxes was a non-cash expense since we had available net operating loss carryforwards and tax credits to offset the cash payment of taxes.

For the year ended December 31, 2004, we recorded a net income tax benefit of $40.3 million. The benefit consisted of a reduction in the valuation allowance relating to our deferred tax assets of $46.1 million, the recognition of $2.1 million in tax credits and an additional tax benefit for operating losses of $1.5 million. This was offset with a charge of $9.4 million, which includes federal, state and local and foreign taxes.

Our consolidated effective tax rate for the year ended December 31, 2005 was 29.6%. Our consolidated effective tax rate can vary from period to period depending on, among other factors, the geographic and business mix of our earnings.

As of December 31, 2005, we had net operating loss carryforwards for income tax purposes of $104.1 million. We recorded a valuation allowance of $15.2 million against the gross deferred tax assets of $57.9 million arising from the net operating loss carryforwards and temporary differences relating to the deductibility of certain expenses for book and tax purposes. This valuation allowance was deemed appropriate due to available evidence indicating that some of the deferred tax assets might not be realized in future years.

Quarterly Results of Operations

Our quarterly results have varied significantly as a result of:


	•	changes in trading volume due to market conditions, a decrease in the number of trading days in certain quarters, and seasonality effects caused by slow-downs in trading activity during certain periods;

	•	increases in the number of broker-dealers and institutional investors using our trading platform as well as increased usage by existing clients;

	•	expansion of the products we offer to our clients; and

	•	variance in our expenses.

The following table sets forth certain consolidated quarterly income statement data for the eight quarters ended December 31, 2006. In our opinion, this unaudited information has been prepared on a basis consistent with our annual financial statements and includes all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the unaudited quarterly data. This information should be read in conjunction with our Consolidated Financial Statements and related Notes included in this Annual Report onForm 10-K. The results of operations for any quarter are not necessarily indicative of results that we may achieve for any subsequent periods.

(7)		During the three months ended December 31, 2005, we reduced the valuation allowance by $2.9 million to $15.2 million based on management’s current assessment of the factors impacting the valuation allowance previously recorded. Such factors include management’s expectation of continuing future profitable operations and judgment concerning future utilization of certain net operating losses that are subject to Section 382 limitations prior to their expiration. In addition, we adjusted the income tax rate used for recording the deferred tax assets, resulting in a decrease in the deferred tax assets and an increase in tax expense of $1.8 million. Without giving effect to the adjustment to the income tax rate used for recognizing the deferred tax assets and the reduction in the valuation allowance against the deferred tax assets, our net income for the three months ended December 31, 2005 would have been $1.0 million.

The following tables set forth trading volume and average fee per million traded for the eight quarters ended December 31, 2006.

On a quarterly basis, our commission revenues have fluctuated primarily as a result of changes in the overall volumes in the markets in which we operate as well as our share of those volumes. U.S. high-grade volume in 2006 increased by $17.8 billion or 10.0% when compared to 2005.

European high-grade trading volume increased by $14.3 billion or 19.4% between 2005 and 2006 as a result of increased volume traded by existing clients on the platform.

Other trading volume increased by $8.4 billion or 17.5%, primarily as a result of an increase in the volume of agency bonds traded, partially offset by a decline in new issue transactions.

Liquidity and Capital Resources

Since our inception, we have met our funding requirements through the issuance of our preferred stock, internally generated funds and our initial public offering in November 2004. Cash and cash equivalents, Short-term investments and Securities-available-for-sale totaled $103.4 million at December 31, 2004, $118.1 million at December 31, 2005 and $131.0 million at December 31, 2006. The changes in the balances were the result of operating cash flow. In January 2005, we invested the net proceeds of our initial public offering in commercial paper, municipal bonds and short-term corporate bonds. To limit our exposure to foreign currency fluctuations from MarketAxess Europe Limited and MarketAxess Leasing Limited, our U.K. subsidiaries, we use foreign currency forward contracts in which we sell Pounds Sterling and buy U.S. dollars for forward settlement.

Current assets consists of Cash and cash equivalents, Short-term investments, Securities provided as collateral, Accounts receivable and Prepaid expenses and other assets. Current assets as a percentage of total assets represented 70.4% at December 31, 2004, 73.4% at December 31, 2005 and 75.6% at December 31, 2006. In addition, our current ratio, which is computed by dividing current assets by current liabilities, was 6.1 at December 31, 2004, 7.1 at December 31, 2005 and 8.1 at December 31, 2006. Current liabilities were comprised of Accrued employee compensation, Deferred revenue, Accounts payable and accrued expenses. We have no long-term or short-term debt and do not maintain bank lines of credit.

On October 26, 2006, our Board of Directors authorized a stock repurchase program for up to $40 million of our common stock. Shares repurchased under the program will be held in treasury for future use. As of December 31, 2006, we had repurchased 190,500 shares at a purchase price of $2.7 million. Through March 9, 2007, a total of 1,475,756 shares had been repurchased at a cost of $19.4 million.

Our contingent liabilities and commitments consist of our non-cancelable leases for office space and our foreign exchange forward contracts. As of December 31, 2006, the minimum rentals under our leases, net of sublease income, were as follows:

A standby letter of credit is used as security for a long-term office space lease and is collateralized by U.S. Treasury securities with a fair value of $3.3 million as of December 31, 2006. U.S. Treasury securities are replaced as they mature to continually collateralize the letter of credit.

Operating Activities

Commissions, information and user access fees, and general operating expenses are the key factors that influence our cash flow. At December 31, 2006, we had Cash and cash equivalents of $82.0 million, an increase of $23.8 million or 40.9% compared to $58.2 million at December 31, 2005. For the year ended, December 31, 2005, Cash and cash equivalents decreased by $39.5 million compared to $97.7 million at December 31, 2004.

As of December 31, 2006, Cash and cash equivalents represented 40.1% of our total assets compared to 30.6% and 55.3% at December 31, 2005 and 2004, respectively. The increase in Cash and cash equivalents in 2006 was due primarily to net cash provided by operations. The decrease in Cash and cash equivalents in 2005 was primarily due to investments in Securities-available-for-sale. The increase of Cash and cash equivalents in 2004 was primarily from the net proceeds of our initial public offering.

Net cash provided by operating activities was $17.1 million, $16.9 million and $20.7 million for the years ended December 31, 2006, 2005 and 2004, respectively.

Cash provided by operating activities of $17.1 million for the year ended December 31, 2006 consisted of net income of $5.4 million, adjusted for non-cash charges, primarily consisting of charges of $6.7 million for depreciation and amortization, $6.4 million related to the issuance of stock options and restricted stock, $0.9 million for deferred taxes and a $0.7 million provision for bad debts. These non-cash charges were offset by an increase in cash used for working capital of $3.0 million.

Cash provided by operating activities of $16.9 million for the year ended December 31, 2005 consisted of net income of $8.1 million, adjusted for non-cash charges, primarily consisting of charges of $4.6 million for depreciation and amortization, $1.9 million related to the issuance of stock options and restricted stock and a $3.0 million charge for deferred taxes. These non-cash charges were offset by an increase in cash used for working capital of $1.7 million.

Cash provided by operating activities of $20.7 million for the year ended December 31, 2004 consisted of net income of $57.6 million, adjusted for non-cash charges, primarily consisting of $40.4 million for deferred taxes, $3.5 million for depreciation and amortization and $2.5 million for warrant-related expense. These non-cash charges were offset by an increase in cash used for working capital of $2.8 million.

Investing Activities

For the years ended December 31, 2006 and 2004, net cash provided by investing activities was $4.2 million and $2.5 million, respectively. Net cash used in investing activities was $59.0 million for the year ended December 31, 2005.

Cash provided by investing activities of $4.2 million for the year ended December 31, 2006 consisted of net proceeds of Securities-available-for-sale of $11.0 million, offset by purchases of furniture, equipment and leasehold improvements of $2.7 million and capitalization of software development costs of $4.1 million.

Cash used in investing activities of $59.0 million for the year ended December 31, 2005 consisted of net purchases of Securities-available-for-sale of $60.0 million, purchases of furniture, equipment and leasehold improvements of $1.4 million and capitalization of software development costs of $3.4 million, offset by maturity of short-term investments of $5.8 million.

Cash provided by investing activities of $2.5 million for the year ended December 31, 2004 consisted of net maturities of short-term investments of $9.8 million, offset by purchases of furniture, equipment and leasehold improvements of $3.4 million, capitalization of software development costs of $3.6 million, and maturities of securities provided as collateral of $0.3 million.

Financing Activities

Net cash provided by financing activities was $2.8 million, $2.7 million and $54.2 million for the years ended December 31, 2006, 2005 and 2004, respectively.

Cash provided by financing activities in 2006 was primarily the result of stock option exercises of $3.8 million and $1.7 million from excess tax benefits from share-based compensation, offset by $2.7 million of treasury stock purchased.

Cash provided by financing activities in 2005 consisted primarily of $2.7 million from the issuance of common stock and the exercise of stock options.

Cash provided by financing activities in 2004 primarily consisted of $53.9 million in proceeds from our initial public offering completed in November 2004.

Other Factors Influencing Liquidity and Capital Resources

We are dependent on our broker-dealer clients, nine of which are also our stockholders, who are not restricted from buying and selling fixed-income securities, directly or through their own proprietary or third-party platforms, with institutional investors. None of our broker-dealer clients is contractually or otherwise obligated to continue to use our electronic trading platform. The loss of, or a significant reduction in the use of our electronic platform by, our broker-dealer clients could reduce our cash flows, affect our liquidity and have a material adverse effect on our business, financial condition and results of operations.

We believe that our current resources are adequate to meet our liquidity needs and capital expenditure requirements for at least the next 12 months. However, our future liquidity and capital requirements will depend on a number of factors, including expenses associated with product development and expansion and new business opportunities that are intended to further diversify our revenue stream. We may also acquire or invest in technologies, business ventures or products that are complementary to our business. In the event we require any additional financing, it will take the form of equity or debt financing. Any additional equity offerings may result in dilution to our stockholders. Any debt financings may involve restrictive covenants with respect to dividends, issuances of additional capital and other financial and operational matters related to our business.

We have two major operating subsidiaries, MarketAxess Corporation and MarketAxess Europe Limited. MarketAxess Corporation is a registered broker-dealer in the U.S. and MarketAxess Europe Limited is a registered alternative trading system in the U.K. As such, they are subject to minimum regulatory capital requirements imposed by their respective market regulators that are intended to ensure general financial soundness and liquidity based on certain minimum capital requirements. The U.S. and the U.K. regulations prohibit a registrant from repaying borrowings from its parent or affiliates, paying cash dividends, making loans to its parent or affiliates or otherwise entering into transactions that result in a significant reduction in its regulatory net capital position without prior notification to or approval from its principal regulator. The capital structures of our subsidiaries are designed to provide each with capital and liquidity consistent with its business and regulatory requirements. As of December 31, 2006, MarketAxess Corporation had net capital of $15.0 million, which was $14.0 million in excess of its required minimum net capital of $1.0 million. MarketAxess Europe Limited had financial resources, as defined by the FSA, of $14.9 million, which was $10.5 million in excess of its required financial resources of $4.4 million.

In June 2006, our U.S. subsidiary, MarketAxess Corporation, commenced operating an anonymous matching service for its broker-dealer clients. MarketAxess Corporation executes trades on a riskless principal basis, which are cleared and settled by an independent clearing broker. The securities clearing agreement that MarketAxess Corporation maintains with the independent clearing broker commenced in December 2004. Under the securities clearing agreement, MarketAxess Corporation maintains a collateral deposit with the clearing broker in the form of cash or U.S. government securities. As of December 31, 2006 and December 31, 2005, the collateral deposit included in Securities and cash provided as collateral on the Consolidated Statements of Financial Condition was $0.5 million. MarketAxess Corporation is exposed to credit risk in the event a contra-party does not fulfill its obligation to complete a transaction. Pursuant to the terms of the securities clearing agreement between MarketAxess Corporation and the independent clearing broker, the clearing broker has the right to charge MarketAxess Corporation for losses resulting from a counterparty’s failure to fulfill its contractual obligations. The losses are not capped at a maximum amount and apply to all trades executed through the clearing broker. At December 31, 2006, MarketAxess Corporation recorded no contingent liabilities with regard to this right. In the ordinary course of business, we enter into contracts that contain a variety of representations, warranties and general indemnifications.

Our maximum exposure from any claims under these arrangements is unknown, as this would involve claims that have not yet occurred. However, based on past experience, we expect the risk of loss to be remote.

Effects of Inflation

Because the majority of our assets are liquid in nature, they are not significantly affected by inflation. However, the rate of inflation may affect our expenses, such as employee compensation, office leasing costs and communications expenses, which may not be readily recoverable in the prices of our services. To the extent inflation results in rising interest rates and has other adverse effects on the securities markets, it may adversely affect our financial position and results of operations.

Recent Accounting Pronouncements

In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments” (“SFAS 155”). SFAS 155 is an amendment of SFAS No. 133 and SFAS No. 140. SFAS 155 permits companies to elect, on adeal-by-deal basis, to apply a fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. SFAS 155 is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006. We do not expect SFAS 155 to have a material impact on our Consolidated Financial Statements.

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets” (“SFAS 156”). SFAS 156 amends SFAS No. 140. SFAS 156 requires that all separately recognized servicing assets and servicing liabilities be initially measured at fair value. For subsequent measurements, SFAS 156 permits companies to choose between an amortization method or a fair value measurement method for reporting purposes. SFAS 156 is effective as of the beginning of a company’s first fiscal year that begins after September 15, 2006. We do not expect SFAS 156 to have a material impact on our Consolidated Financial Statements.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 applies to all tax positions accounted for under SFAS 109. A “tax position” includes current or future reductions in taxable income reported or expected to be reported on a tax return. FIN 48 supplements SFAS 109 by defining the confidence level that a tax position must meet in order to be recognized in the financial statements. The interpretation requires that the tax effects of a position be recognized only if it is “more-likely-than-not” (greater than 50% likelihood) to be sustained based solely on its technical merits as of the reporting date. In making this assessment, a company must assume that the taxing authorities will examine the position. We currently use a more stringent “probable” threshold for recognizing uncertain tax positions. FIN 48 is effective as of the beginning of the first fiscal year beginning after December 15, 2006. At adoption, companies must adjust their financial statements to reflect only those tax positions that are more-likely-than-not to be sustained as of the adoption date. The necessary adjustments, if any, should be recorded directly to the beginning balance of retained earnings in the period of adoption and reported as a change in accounting principle. We are currently evaluating the impact of the adoption of FIN 48 on our Consolidated Financial Statements.

requires that public companies utilize a “dual approach” to assess the quantitative effects of financial misstatements. This dual approach includes both an income statement-focused assessment and a balance sheet-focused assessment. The guidance in SAB 108 must be applied to annual financial statements for fiscal years ending after November 15, 2006. Adoption of SAB 108 did not affect our Consolidated Financial Statements.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We do not expect SFAS 157 to have a material impact on our Consolidated Financial Statements.

In February 2007, the FASB issued SFAS No. 159, “Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits companies to elect to measure eligible financial instruments, commitments and certain other arrangements at fair value at specified election dates with changes in fair value recognized in earnings at each subsequent reporting period. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We do not expect SFAS 159 to have a material impact on our Consolidated Financial Statements.


Item 7A.	*Quantitative and Qualitative Disclosures About Market Risk*

Market risk is the risk of the loss resulting from adverse changes in market rates and prices, such as interest rates and foreign currency exchange rates.

Market Risk

As of December 31, 2006, we had a $49.0 million investment in Securitiesavailable-for-sale. Adverse movements, such as a 10% decrease in the securities underlying these positions or a downturn or disruption in the markets for these positions, could result in a substantial loss. In addition, principal gains and losses resulting from theses positions could on occasion have a disproportionate effect, positive or negative, on our financial condition and results of operations for any particular reporting period.

See Item 1A. Risk Factors, “Risks Related to Our Industry —Economic, political and market factors beyond our control could reduce demand for our services and harm our business, and our profitability could suffer.”

Interest Rate Risk

Interest rate risk represents our exposure to interest rate changes with respect to the money market instruments, U.S. Treasury obligations and short-term fixed-income securities in which we invest. As of December 31, 2006, we invested in primarily federal agency issues and municipal securities of $49.0 million. We do not maintain an inventory of bonds that are traded on our platform.

Derivative Risk

Our limited derivative risk stems from our activities in the foreign currency forward contract market. We use this market to mitigate our U.S. dollar versus Pound Sterling exposure that arises from the activities of our U.K. Subsidiaries. As of December 31, 2006, the notional value of our foreign currency forward contracts was $17.4 million. We do not speculate in any derivative instruments.

Credit Risk

We are exposed to credit risk in our role as trading counterparty to our broker-dealer clients executing trades on the DealerAxess^® platform. We are exposed to the risk that third parties that owe us money, securities or other assets will not perform their obligations. These parties may default on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. Adverse movements in the prices of securities that are the subject of these transactions can increase our risk. Where the unmatched position or failure to deliver is prolonged, there may also be regulatory capital charges required to be taken by us. The policies and procedures we use to manage this credit risk are new and untested. There can be no assurance that these policies and procedures will effectively mitigate our exposure to credit risk.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of MarketAxess Holdings Inc. is responsible for establishing and maintaining adequate internal control over financial reporting as defined inRules 13a-15(f) and15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission inInternal Control — Integrated Framework.

Based on our assessment and those criteria, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2006.

Our management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2006 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
MarketAxess Holdings Inc.:

We have completed integrated audits of MarketAxess Holdings Inc.’s 2006 and 2005 consolidated financial statements and of its internal control over financial reporting as of December 31, 2006, and an audit of its December 31, 2004 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of MarketAxess Holdings Inc. and its subsidiaries at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements 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 of financial statements 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, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 10 to the consolidated financial statements, the Company changed the manner in which it accounts for share-based compensation in 2006.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing on page 74, that the Company maintained effective internal control over financial reporting as of December 31, 2006 based on criteria established inInternal Control — Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established inInternal Control — Integrated Frameworkissued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting 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 effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made

only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

1.	Organization and Principal Business Activity

MarketAxess Holdings Inc. (the “Company”) was incorporated in the State of Delaware on April 11, 2000. Through its subsidiaries, the Company operates an electronic trading platform for corporate bonds and certain other types of fixed-income securities, through which the Company’s active institutional investor clients can access the liquidity provided by its broker-dealer clients. The Company’s multi-dealer trading platform allows its institutional investor clients to simultaneously request competitive, executable bids or offers from multiple broker-dealers, and to execute trades with the broker-dealer of their choice. The Company offers its clients the ability to trade U.S. high-grade corporate bonds, European high-grade corporate bonds, credit default swaps, agencies, high yield and emerging markets bonds. The Company’s DealerAxess^® trading service allows dealers to trade fixed-income securities with each other on its platform. The Company also provides data and analytical tools that help its clients make trading decisions and facilitates the trading process by electronically communicating order information between trading counterparties. The Company’s current participating dealers are: ABN AMRO, Banc of America Securities, Barclays PLC, Bear Stearns, BNP Paribas, Citigroup Global Markets, Credit Suisse, Deutsche Bank Securities, Dresdner Bank AG, DZ Bank AG, FTN Financial, Goldman Sachs, HSBC, ING Financial Markets, JPMorgan, Jefferies and Company, Lehman Brothers, Merrill Lynch, Morgan Stanley, RBC Capital Markets, The Royal Bank of Scotland, Santander Investment Securities, SG Corporate & Investment Banking, UBS and Wachovia Securities.

The Company’s stockholder broker-dealer clients as of January 1, 2006 were ABN Amro, Banc of America Securities, Bear Stearns, BNP Paribas, Credit Suisse, Deutsche Bank, JPMorgan, Lehman Brothers and UBS. All of these broker-dealer clients constitute related parties of the Company (together, the “Stockholder Broker-Dealer Clients”). Moneyline Telerate (“Moneyline”) which provided certain software development services to the Company and had a revenue-sharing agreement with the Company, is considered a related party for the fiscal years 2005 and 2004. In February 2005, the Company ceased using the technology platform that was covered under the Moneyline revenue-sharing agreement. See Note 8, “Related Parties.”

The Company’s U.S. subsidiary, MarketAxess Corporation, is a registered broker-dealer with the U.S. Securities and Exchange Commission (“SEC”) and is a member of the National Association of Securities Dealers, Inc. (“NASD”). The Company also has three international subsidiaries: MarketAxess Europe Limited (“MarketAxess Europe”), which is registered as an Alternative Trading System dealer with the Financial Services Authority (“FSA”) in the United Kingdom (“U.K.”); MarketAxess Leasing Limited (collectively with MarketAxess Europe, the “U.K. Subsidiaries”); and MarketAxess Canada Limited, a Canadian subsidiary that the Company incorporated in May 2003. MarketAxess Canada Limited has applied for registration as an Alternative Trading System dealer under the Securities Act of Ontario and is in the process of seeking approval for membership with the Investment Dealers Association of Canada.

On November 4, 2004, the Company completed the initial public offering of its common stock. Specifically, 5,750,000 shares of common stock, including an aggregate of 750,000 shares of common stock covered by an over-allotment option granted by the Company to the underwriters, were sold at a price to the public of $11.00 per share. The aggregate proceeds to the Company from the offering were $63.2 million before deducting $4.4 million in underwriting discounts and commissions and an estimated $4.9 million in other expenses incurred in connection with the offering. Additionally, prior to the closing of the initial public offering, all outstanding shares of redeemable convertible preferred stock and convertible preferred stock were converted into 14,484,493 shares of common stock and 4,266,310 shares of non-voting common stock.

2.	Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries, MarketAxess Corporation, MarketAxess Europe, MarketAxess Leasing Limited and MarketAxess Canada Limited. All intercompany transactions and balances have been eliminated.

Foreign Currency Translation

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the year; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are included as a cumulative translation adjustment to Accumulated other comprehensive loss on the Consolidated Statements of Financial Condition.

Cash and Cash Equivalents

Cash and cash equivalents include cash maintained at U.S. and U.K. banks and in money market funds. The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Securities and Cash Provided as Collateral

Securities provided as collateral consist of U.S. government obligations and cash. Collectively, these amounts are used as collateral for standby letters of credit, as collateral for foreign currency forward contracts to hedge the Company’s net investments in the U.K. Subsidiaries and as collateral for a broker-dealer clearance account.

SecuritiesAvailable-for-Sale

The Company has classified certain of its marketable securities asAvailable-for-sale securities. Unrealized marketable securities gains and losses are reflected as a net amount under the caption of Accumulated other comprehensive loss on the Consolidated Statements of Financial Condition. Realized gains and losses are recorded within the Consolidated Statements of Operations under the caption General and administrative expense. For the purpose of computing realized gains and losses, cost is determined on a specific identification basis.

The Company assesses whether another-than-temporary impairment loss on the investments has occurred due to declines in fair value or other market conditions. Declines in fair values that are considered other than temporary are recorded as charges in the Consolidated Statements of Operations.

Allowance for Doubtful Accounts

The Company continually monitors collections and payments from its customers and maintains an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified. Additions to the allowance for doubtful accounts are charged to Bad debt expense, which is included in General and administrative expense in the Company’s Consolidated Statements of Operations.

The allowance for doubtful accounts was $0.8 million, $0.4 million and $0.3 million as of December 31, 2006, 2005 and 2004, respectively. The provision for bad debts was $0.7 million, $0.4 million and $0.3 million for the years ended December 31, 2006, 2005 and 2004, respectively. Write-offs and other charges against the allowance for doubtful accounts were $0.3 million, $0.2 million and $0 for the years ended December 31, 2006, 2005 and 2004, respectively.

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three years. Leasehold improvements are stated at cost and are amortized using the straight-line method over the lesser of the life of the improvement or the remaining term of the lease.

Software Development Costs

In accordance with Statement of PositionNo. 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,” the Company capitalizes certain costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. The Company capitalizes employee compensation and related benefits and third party consulting costs incurred during the preliminary software project stage. Once the product is ready for its intended use, such costs are amortized on a straight-line basis over three years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Foreign Currency Forward Contracts

The Company follows Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”), and enters into foreign currency forward contracts to hedge its net investment in the U.K. Subsidiaries. Accordingly, gains and losses on these transactions are deferred and included in Accumulated other comprehensive loss on the Consolidated Statements of Financial Condition.

Revenue Recognition

The majority of the Company’s revenues are derived from commissions for trades executed on its platform that are billed to its broker-dealer clients on a monthly basis. Commissions are generally calculated as a percentage of the notional dollar volume of bonds traded on the platform and vary based on the type and maturity of the bond traded. Under the Company’s transaction fee plans, bonds that are more actively traded or that have shorter maturities are generally charged lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions.

The Company also derives revenues from information and user access fees, license fees, investment income and other income.

The Company enters into agreements with its broker-dealer clients pursuant to which the Company provides access to its platform through a non-exclusive and non-transferable license. Broker-dealer clients, other than those that previously made equity investments in the Company, pay an initial license fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial license fee varies by agreement and at a minimum is intended to cover the initialset-up costs incurred to enable a broker-dealer to begin using the Company’s electronic trading platform. Revenue is recognized in the first three months of the agreement in the estimated amount of theset-up costs incurred (50% in the first month, 40% in the second month and 10% in the third month), and the remaining amount is deferred and recognized ratably over the initial term of the agreement, which is generally three years. The Company anticipates that license fees will be a less material source of revenues on a going-forward basis.

Stock-Based Compensation for Employees

Prior to January 1, 2006, the Company accounted for stock-based employee compensation plans in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), as permitted by Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation”

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(“SFAS 123”). In accordance with APB 25, the Company accounted for stock-based awards to employees and directors using the intrinsic value method.

On December 16, 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123 (revised 2004), “Share-Based Payment” (“SFAS 123R”), which is a revision of SFAS 123.

Effective January 1, 2006, the Company adopted SFAS 123R, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees based on estimated fair values. In accordance with SFAS 123R, non-employee members of the Board of Directors are treated as employees. SFAS 123R supersedes the Company’s previous accounting under APB 25 for periods beginning in fiscal 2006. In March 2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to SFAS 123R. The Company has applied the provisions of SAB 107 in its adoption of SFAS 123R.

The Company adopted SFAS 123R using the modified prospective transition method, which requires the application of the accounting standard as of January 1, 2006. In accordance with the modified prospective transition method, the Company’s Consolidated Financial Statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123R.

SFAS 123R requires companies to estimate the fair value of share-based payment awards on the date of grant. Stock-based compensation expense recognized in the Company’s Consolidated Statements of Operations for the year ended December 31, 2006 included compensation expense for share-based payment awards granted prior to, but not yet vested, as of December 31, 2005 based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS 123 and compensation expense for the share-based payment awards granted subsequent to December 31, 2005 based on the grant date fair value estimated in accordance with the provisions of SFAS 123R. As stock-based compensation expense recognized in the Consolidated Statements of Operations for the year ended December 31, 2006 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Company’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred.

Had compensation expense for employee stock-based awards been determined based on the fair value at grant date consistent with SFAS No. 123R, the Company’s Net income for 2005 and 2004 would have been as follows:


	Year Ended December 31,
	2005		2004
	(In thousands, except per share amounts)

Net income
As reported	$	8,142	$	57,587

Basic net income per common share — as reported	$	0.29	$	6.76

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table presents the assumptions used for the Black-Scholes option-pricing model to determine the per share weighted- average fair value for options granted during the years ended December 31, 2005 and 2004:


	Year Ended December 31,
	2005			2004

Weighted-Average Expected Life (years)		3.00			3.00
Weighted-Average Risk-Free Interest Rate		3.63	%		2.74	%
Weighted-Average Expected Volatility		20.72	%		28.25	%

On November 10, 2005, the FASB issued FASB Staff PositionNo. FAS 123R-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.” The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (“APIC pool”) related to the tax effects of employee stock-based compensation, and to determine the subsequent impact on the APIC pool and Consolidated Statements of Cash Flows of awards that are outstanding upon the adoption of SFAS 123R. The Company has used the long-method calculation, pursuant to SFAS 123R, to determine its APIC pool as of December 31, 2005. As of December 31, 2006, the Company has calculated the APIC pool to be $2.5 million.

Prior to the adoption of SFAS 123R, the Company presented all tax benefits resulting from the exercise of stock options as operating cash flows in the Consolidated Statements of Cash Flows. SFAS 123R requires the cash flows resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows. The excess tax benefit for the year ended December 31, 2006 of $1.7 million, classified as a financing cash flow, would have been classified as an operating cash flow if the Company had not adopted SFAS 123R.

Income Taxes

Earnings Per Share

SFAS No. 128, “Earnings Per Share,” requires the presentation of basic and diluted earnings per share (“EPS”) in the Consolidated Statements of Operations. Basic EPS is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS is computed using the same method as basic EPS, but in the denominator, shares of common stock outstanding reflect the potential dilution that could occur if convertible securities or other contracts to issue common stock were converted into or exercised for common stock.

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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments” (“SFAS 155”). SFAS 155 is an amendment of SFAS No. 133 and SFAS No. 140. SFAS 155 permits companies to elect, on adeal-by-deal basis, to apply a fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. SFAS 155 is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006. The Company does not expect SFAS 155 to have a material impact on its Consolidated Financial Statements.

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets” (“SFAS 156”). SFAS 156 amends SFAS No. 140. SFAS 156 requires that all separately recognized servicing assets and servicing liabilities be initially measured at fair value. For subsequent measurements, SFAS 156 permits companies to choose between an amortization method or a fair value measurement method for reporting purposes. SFAS 156 is effective as of the beginning of a company’s first fiscal year that begins after September 15, 2006. The Company does not expect SFAS 156 to have a material impact on its Consolidated Financial Statements.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 applies to all tax positions accounted for under SFAS 109. A “tax position” includes current or future reductions in taxable income reported or expected to be reported on a tax return. FIN 48 supplements SFAS 109 by defining the confidence level that a tax position must meet in order to be recognized in the financial statements. The interpretation requires that the tax effects of a position be recognized only if it is “more-likely-than-not” (greater than 50% likelihood) to be sustained based solely on its technical merits as of the reporting date. In making this assessment, a company must assume that the taxing authorities will examine the position. The Company currently uses a more stringent “probable” threshold for recognizing uncertain tax positions. FIN 48 is effective as of the beginning of the first fiscal year beginning after December 15, 2006. At adoption, companies must adjust their financial statements to reflect only those tax positions that are more-likely-than-not to be sustained as of the adoption date. The necessary adjustments, if any, should be recorded directly to the beginning balance of retained earnings in the period of adoption and reported as a change in accounting principle. The Company is currently evaluating the impact of the adoption of FIN 48 on its Consolidated Financial Statements.

In September 2006, the SEC released Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 requires that public companies utilize a “dual approach” to assess the quantitative effects of financial misstatements. This dual approach includes both an income statement-focused assessment and a balance sheet-focused assessment. The guidance in SAB 108 must be applied to annual financial statements for fiscal years ending after November 15, 2006. Adoption of SAB 108 did not affect the Company’s Consolidated Financial Statements.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. The Company does not expect SFAS 157 to have a material impact on its Consolidated Financial Statements.

In February 2007, the FASB issued SFAS No. 159, “Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits companies to elect to measure eligible financial instruments, commitments and certain other arrangements at fair value at specified election dates, with changes in fair value recognized in earnings at each subsequent reporting period. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company does not expect SFAS 159 to have a material impact on its Consolidated Financial Statements.

The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which the temporary differences become deductible. If it is not more likely than not

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

that some portion or all of the gross deferred income tax assets will be realized in future years, a valuation allowance is recorded.

In 2000 and 2001, MarketAxess Holdings Inc. and MarketAxess Corporation had an ownership change within the meaning of Section 382 of the Internal Revenue Code. As a result, net operating loss carryforwards existing at the date of the ownership change of $39.2 million are subject to significant limitations. The Company recorded a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized. In addition, the Company’s net operating loss and tax credit carryforwards may be subject to additional annual limitations if there is a 50% or greater change in the Company’s ownership, as determined over a rolling three-year period.

During the years ended December 31, 2006, 2005 and 2004, the Company reduced the valuation allowance by $0.5 million, $2.9 million and $46.1 million, respectively, based on management’s current assessment of the factors impacting the valuation allowance previously recorded. Such factors included management’s expectation of continuing future profitable operations and judgment concerning future utilization of certain net operating losses that are subject to Section 382 limitations prior to their expiration. In addition, during 2005 the Company adjusted the income tax rate used for recording the deferred tax assets, resulting in a decrease in the deferred tax assets and an increase in tax expense of $1.7 million.

The rollforward of the valuation allowance is as follows:


	Year Ended December 31,
	2006			2005
	(In thousands)

Valuation allowance at beginning of period	$	15,218		$	18,136
Increase (decrease) to valuation allowance attributable to:
Net operating losses		(330	)		(3,419	)
Temporary differences		97			161
Tax credits		(217	)		340

Valuation allowance at end of period	$	14,768		$	15,218

As discussed in Note 9, during the years ended December 31, 2006 and 2005, several related parties exercised a total of 2,620,802 warrants into 2,620,098 shares of common stock through non-cash exercises, resulting in a benefit for federal income taxes purposes of $7.3 million, which when realized would result in an increase in Additional paid-in capital. Management believes that there is sufficient uncertainty with regard to the ultimate realization of this tax credit and therefore has not recognized the credit in the Consolidated Statements of Financial Condition as of December 31, 2006.

The Company had an agreement with Moneyline to assist in developing the Company’s U.S. high-grade corporate bond and European electronic trading platforms. In consideration of Moneyline’s provision of services under the agreement, the Company paid Moneyline a variable monthly fee. In addition, Moneyline was entitled to share in a portion of the Company’s quarterly net revenues, as defined in the agreement. In May 2004, the Company ceased using the software relating to the legacy U.S. high-grade trading platform developed with the assistance of Moneyline and began using internally-developed software and in February 2005 also migrated the European high-grade trading platform to the internally developed software. The agreement terminated in February 2005.

As of December 31, 2006 and 2005, the Company had loans outstanding to the Chief Executive Officer of $1.4 million and $1.3 million, respectively, which are described in more detail in Footnote 9, “Stockholders’ Equity.” The accrued interest on the loans is recorded in Accounts receivable and the principal amount is recorded as a Receivable for common stock subscribed in Stockholders’ equity on the Consolidated Statements of Financial Condition.


9.	Stockholders’ Equity

Common Stock

As of December 31, 2006 and 2005, the Company had 110,000,000 authorized shares of voting common stock and 10,000,000 authorized shares of non-voting common stock. Voting common stock entitles the holder to one vote per share of common stock held.

Non-voting common stock is convertible on aone-for-one basis into shares of voting common stock at any time subject to a limitation on conversion to the extent such conversion would result in a stockholder, together with its affiliates, owning more than 9.99% of the outstanding shares of common stock. During 2006, a total of 1,275,951 shares of non-voting common stock were converted to voting common stock.

On March 30, 2004, the Company’s Board of Directors authorized, and on November 1, 2004 the Company effectuated, aone-for-three reverse stock split of shares of voting common stock and non-voting common stock to be effective prior to the closing of the Company’s initial public offering. All references in these financial statements to the number of shares of voting common stock and non-voting common stock of the Company, securities convertible or exercisable therefore and per share amounts have been restated for all periods presented to reflect the effect of the common stock reverse stock split.

On October 26, 2006, the Board of Directors of the Company authorized a share repurchase program for up to $40.0 million of the Company’s common stock. The Company intends to repurchase the shares in the open market or through privately negotiated transactions, at times and prices considered appropriate by the Company. Shares

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

repurchased under the program will be held in treasury for future use. During December 2006, 190,500 shares were repurchased at a cost of $2.7 million.

Common Stock Subscribed

In 2001, the Company awarded 289,581 shares to the Company’s Chief Executive Officer at $3.60 per share, which vested over a three-year period. The common stock subscribed was issued in 2001 in exchange for eleven-year promissory notes that bear interest at the applicable federal rate and are collateralized by the subscribed shares.

Warrants

In April 2000, the Board of Directors initiated a warrant program that commenced on February 1, 2001. Under this program, the Company reserved for issuance 5,000,002 shares of common stock. The warrants were issued to holders of Series A, C, E and I redeemable convertible preferred stock (the “Warrant Holders”). The Warrant Holders are entitled to purchase shares of common stock from the Company at an exercise price of $.003 through and including November 30, 2008.

The warrants were issued to the Warrant Holders at the time that they made an equity investment in the Company. The warrant program had two distinct pieces, a U.S. and a European portion, under which the aggregate number of shares underlying the warrant to be allocated in each three-month period was fixed. Allocations under this program commenced on May 1, 2001 for the U.S. portion and on June 1, 2002 for the European portion and were based on each broker-dealer client’s respective commissions as a percentage of the total commissions from the six participating Warrant Holders, calculated on a quarterly basis. The final share allocations under the warrant program occurred on March 1, 2004.

Shares allocated under the warrant program were expensed on a quarterly basis at fair market value in accordance with SFAS 123. The Company determined fair market value of the shares issuable upon exercise of the warrant using the Black-Scholes option-pricing model. To assist management in determining fair market value of the shares issuable, independent valuations of the Company’s common stock were undertaken as of December 31, 2001, December 31, 2002, September 30, 2003 and December 31, 2003. A number of factors were considered in the valuations, including the Company’s current financial condition, its future earning capacity, the market price of publicly quoted corporations in similar lines of business and the values of prior sales of preferred stock.

In March 2001, in connection with the acquisition of Trading Edge, the Company also assumed warrants issued by Trading Edge, which were converted into warrants exercisable to purchase 7,967 shares of the Company’s common stock. During the year ended December 31, 2005, these warrants expired unexercised.

During the year ended December 31, 2005, two Stockholder Broker-Dealer Clients converted 1,325,602 warrants into 1,325,249 shares of common stock through non-cash exercises. During the year ended December 31, 2006, two Stockholder Broker-Dealer Clients converted 1,295,004 warrants into 1,294,849 shares of common stock through non-cash exercises.

10.	Stock-Based Compensation Plans

The Company’s 2000 and 2001 Stock Incentive Plans (the “2000 and 2001 Plans”) provide for the grant of options or restricted stock as incentives and rewards to encourage employees, consultants and non-employee directors to participate in the long-term success of the Company. The 2000 and 2001 Plans provide for the granting of shares of the Company’s common stock at fair value or at a value other than fair value (determined by the Board of Directors or a committee thereof) on the date the option is granted. Generally, option grants have provided for vesting over a three-year period, at a rate of one-third after one year from the grant date and with the remaining two-thirds vesting on an equal monthly basis over the remaining two-year period. Options expire ten years from the date of grant. On November 2, 2004, most of the shares of the Company’s common stock available for grant under the 2000 and 2001 Plans were transferred to the Company’s 2004 Stock Incentive Plan (the “2004 Plan”) and no shares are available for grant under the 2000 and 2001 Plans other than shares that become available as a result of expired, terminated or cancelled awards, or shares that are delivered or exchanged by participants as payment upon the exercise of awards.

In 2004, the Company adopted the 2004 Plan to enable it to offer certain of the Company’s key employees, consultants and non-employee directors equity-based awards in the Company. The terms of the 2004 Plan are substantially the same as those in the 2000 and 2001 Plans, except as follows: the maximum aggregate number of shares available for grant is different; the Compensation Committee of the Board of Directors (the “Committee”) has flexibility to grant stock appreciation rights, performance shares, performance units or other stock-based awards (in addition to stock options and restricted stock); and rights of first refusal and repurchase rights do not apply to awards granted under the 2004 Plan. The Committee is appointed by the Board of Directors, consists of at least two non-employee directors and will administer the 2004 Plan. With respect to the application of the 2004 Plan to non-employee directors, the entire Board of Directors will act as the Committee. The 2004 Plan permits the Company to grant stock options (including incentive stock options to employees), stock appreciation rights, restricted stock, performance shares, performance units and other stock-based awards (including, without limitation, restricted stock units) to certain key employees, consultants and non-employee directors, as determined by the Committee in its sole discretion. Through April 27, 2006, up to 2,400,000 shares of the Company’s common stock, plus 684,802 shares of common stock transferred to the 2004 Plan from the 2000 and 2001 Plans on November 2, 2004, could have been issued under the 2004 Plan (subject to adjustment to reflect certain transactions and events specified in the 2004 Plan). On June 7, 2006, stockholder approval was obtained for an amendment and restatement of the 2004 Plan to, among other things, increase the number of shares authorized for issuance under the 2004 Plan from 3,084,802 to

MARKETAXESS HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

9,754,802 shares. The Board had previously approved the amended and restated 2004 Plan effective April 28, 2006, subject to stockholder approval.

The 2004 Plan provides the Committee with authority and flexibility to determine the terms and conditions of the awards at the time of grant. The 2004 Plan provides the Committee the flexibility to grant awards that are not subject to the deduction limits under Section 162(m) of the Internal Revenue Code.

Total stock-based compensation expense for the years ended December 31, 2006, 2005 and 2004 was as follows:


	Year Ended December 31,

Total stock — based compensation	$	6,432	$	2,507	$	1,903

As discussed in Note 2, the Company adopted SFAS 123R on January 1, 2006. The incremental stock-based compensation expense in 2006 related to the adoption of SFAS 123R was $3.2 million.

As a result of adopting SFAS 123R, the Company’s Net income for the year ended December 31, 2006 was $1.8 million less than if it had continued to account for stock-based compensation under APB 25. Basic EPS for the year ended December 31, 2006 would have been $0.24 if the Company had not adopted SFAS 123R, compared to reported basic EPS for the year of $0.18. Diluted EPS for the year ended December 31, 2006 would have been $0.21 if the Company had not adopted SFAS 123R, compared to reported diluted EPS for the year of $0.15.

The Company records stock-based compensation expense for employees in Employee compensation and benefits and for non-employee directors and consultants in General and administrative expenses in the Consolidated Statements of Operations.

During the third quarter of 2006, the Company identified a difference in U.S. and U.K. accounting treatment for taxes ultimately payable upon the exercise of stock options and vesting of restricted stock for grants to U.K. employees. This difference in accounting was corrected through a reversal of the reserve balance of $0.2 million during the year ended December 31, 2006.

Stock Options

The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton closed-form model (“Black-Scholes”). The Company believes that the use of the Black-Scholes model meets the fair value measurement objectives of SFAS 123R and reflects all substantive characteristics of the instruments being valued. The determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the awards, the risk-free interest rate and the expected term. Expected volatilities are based on historical volatility of the Company’s stock and a peer group. The risk-free interest rate is based on U.S. Treasury securities with a maturity

value approximating the expected term of the option. The expected term represents the period of time that options granted are expected to be outstanding based on actual and projected employee stock option exercise behavior and was increased from four years to five years in May 2006.

The following table represents the assumptions used for the Black-Scholes option-pricing model to determine the per share weighted-average fair value for options granted for the year ended December 31, 2006:

As of December 31, 2006, there was $8.0 million of total unrecognized compensation cost related to non-vested stock options granted under the 2000, 2001 and 2004 Plans. That cost is expected to be recognized over a weighted-average period of 2.0 years.

Restricted Stock

Restricted stock granted under the 2004 Plan generally vests over a period of three years. Certain grants vest after five years, but contain provisions that allow for accelerated vesting over a shorter term if defined performance criteria are met. Compensation expense is measured at the grant date and recognized ratably over the vesting period. The Company considers the likelihood of meeting the performance criteria in determining the amount to expense on a periodic basis.

The following table reports restricted stock activity during the years ended December 31, 2005 and 2006:

11.	Commitments and Contingencies

The Company leases office space and equipment under non-cancelable lease agreements expiring at various dates through 2015. These leases are subject to escalation based on certain costs incurred by the landlord. Minimum rental commitments under such leases, net of sublease income, are as follows:


Year Ended December 31,	Minimum Rentals
	(In thousands)

2007	$	2,501
2008		2,509
2009		2,516
2010		1,375
2011		986
2012 and thereafter		3,578

The rental expense for the years ended December 31, 2006, 2005 and 2004 was $2.7 million, $2.0 million and $1.8 million, respectively, which is included in General and administrative expenses in the Consolidated Statements of Operations. Rental expense has been recorded based on the total minimum lease payments after giving effect to rent abatement and concessions, which are being amortized on a straight-line basis over the life of the lease, and sublease income.

The Company has entered into a sublease agreement on one of its leased properties through the April 2011 lease termination date. Monthly sublease income is $0.1 million. A loss on the sublease was recorded in 2001. The sublease loss accrual at December 31, 2006 and 2005 was $0.9 million and $1.1 million, respectively.

Between May 2002 and May 2005, the Company subleased a portion of a leased space in London. The sublessee exercised its early termination option as provided in the agreement and paid MarketAxess Europe an early termination fee of $0.2 million in May 2005. MarketAxess Europe now occupies the space.

The Company is contingently obligated for standby letters of credit that were issued to landlords for office space. The Company uses a U.S. government obligation as collateral for these standby letters of credit. This collateral is included with Securities and cash provided as collateral on the Consolidated Statements of Financial Condition and had a fair market value as of December 31, 2006 and 2005 of $3.3 million.

In June 2006, MarketAxess Corporation commenced operating an anonymous matching service for its broker-dealer clients. MarketAxess Corporation executes trades on a riskless principal basis, which are cleared and settled by an independent clearing broker. The securities clearing agreement that MarketAxess Corporation maintains with the independent clearing broker commenced in December 2004. Under the securities clearing agreement, MarketAxess Corporation maintains a collateral deposit with the clearing broker in the form of cash or U.S. government securities. As of December 31, 2006 and 2005, the collateral deposit included in Securities and cash provided as collateral on the Consolidated Statements of Financial Condition was $0.5 million. MarketAxess Corporation is exposed to credit risk in the event a contra-party does not fulfill its obligation to complete a transaction. Pursuant to the terms of the securities clearing agreement between MarketAxess Corporation and the independent clearing broker, the clearing broker has the right to charge MarketAxess Corporation for losses resulting from a counterparty’s failure to fulfill its contractual obligations. The losses are not capped at a maximum amount and apply to all trades executed through the clearing broker. At December 31, 2006, MarketAxess Corporation recorded no contingent liabilities with regard to this right.

In the normal course of business, the Company enters into contracts that contain a variety of representations, warranties and general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, based on experience, the Company expects the risk of loss to be remote.

For the year ended December 31, 2006, the Company incurred severance payments related to terminated employees totaling $1.7 million. The severance payments were recorded in Employee compensation and benefits on the Consolidated Statements of Operations. As of December 31, 2006, $1.0 million remained unpaid and was recorded in Accrued employee compensation on the Consolidated Statements of Financial Condition. The Company anticipates that all accrued but unpaid amounts will be disbursed in 2007.

In January 2007, two former employees of the Company commenced arbitration proceedings before the National Association of Securities Dealers (“NASD”) against the Company arising out of the expiration of certain vested and unvested stock options and unvested restricted shares issued to them. The claims made by these two former employees total $4.5 million plus interest.

One former employee has alleged that the Company wrongfully prevented him from exercising his vested options when he sought to do so and that the Company wrongfully claimed that such options had expired on the previous day.

The other former employee has alleged that the Company wrongfully failed to accelerate the vesting of his then unvested options and restricted shares upon his termination and to waive the90-day time period within which he was required to exercise his vested options. This former employee also alleges that he is entitled to a declaration that certain provisions in the Company’s 2004 Stock Incentive Plan are invalid and unenforceable under applicable law. He further alleges that he is entitled to a bonus for the approximately five months that he worked for the Company during 2006.

The Company believes that both cases are without merit and intends to vigorously defend them. The Company is required to answer, move or otherwise respond to both arbitration claims during March 2007. Based on currently available information, management believes that the likelihood of a material loss is not probable. Accordingly, no amounts have been provided in the accompanying financial statements. However, arbitration is subject to inherent uncertainties and unfavorable rulings could occur.


12.	Segment Information

The Company’s operations as an electronic multi-dealer platform for the trading of fixed-income securities constitute a single business segment pursuant to SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” Because of the highly integrated nature of the financial markets in which the Company competes and the integration of the Company’s worldwide business activities, the Company believes that results by geographic region or client sector are not necessarily meaningful in understanding its business.

14.	Accounting for Foreign Currency Forward Contracts and Hedging Activities

The Company enters into foreign currency forward contracts with a non-controlling stockholder to hedge its exposure to variability in foreign currency cash flows resulting from the net investments in its U.K. Subsidiaries. The Company assesses each foreign currency forward contract to ensure that it is highly effective at reducing the exposure being hedged. The Company designates each foreign currency forward contract as a hedge, assesses the risk management objective and strategy, including identification of the hedging instrument, the hedged item and the risk exposure and how effectiveness is to be assessed prospectively and retrospectively. These hedges are for a one-month or three-month period and are used to limit exposure to foreign currency exchange rate fluctuations. Gains or
