NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — Unaudited

1. Organization and Principal Business Activity

MarketAxess Holdings Inc. (the “Company” or “MarketAxess”) 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 other types of fixed-income instruments through which the Company’s 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 and asset-backed and preferred securities. The Company also executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which then settle through a third-party clearing organization. Through its Corporate BondTicker™ service, the Company provides fixed-income market data, analytics and compliance tools that help its clients make trading decisions. In addition, the Company provides FIX (Financial Information eXchange) message management tools, connectivity solutions and ancillary technology services that facilitate the electronic communication of order information between trading counterparties.

For 2011, JPMorgan Chase & Co. (“JPM”) was the Company’s sole stockholder broker-dealer client (the “Stockholder Broker-Dealer Client”). During the first quarter of 2012, JPM sold its shares of the Company’s common stock and is no longer considered a related party. See Note 7, “Related Party” and Note 13, “Share Repurchases.”

2. Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated. These consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. The consolidated financial information as of December 31, 2011 has been derived from audited financial statements not included herein.

These unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) with respect to Form 10-Q and reflect all adjustments that, in the opinion of management, are normal and recurring, and that are necessary for a fair statement of the results for the interim periods presented. In accordance with such rules and regulations, certain disclosures that are normally included in annual financial statements have been omitted. Interim period operating results may not be indicative of the operating results for a full year.

Cash and Cash Equivalents

Cash and cash equivalents includes cash and money market instruments that are primarily maintained at one major global bank. Given this concentration, the Company is exposed to certain credit risk. The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Securities Available-for-Sale

The Company classifies its marketable securities as available-for-sale securities. Unrealized marketable securities gains and losses, net of taxes, are reflected as a net amount under the caption of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Realized gains and losses are recorded in the Consolidated Statements of Operations in other revenues. For the purpose of computing realized gains and losses, cost is determined on a specific identification basis.

8

The Company assesses whether an other-than-temporary impairment loss on the investments has occurred due to declines in fair value or other market conditions. The portion of an other-than-temporary impairment related to credit loss is recorded as a charge in the Consolidated Statements of Operations. The remainder is recognized in accumulated other comprehensive loss if the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security prior to recovery. No charges for other-than-temporary losses were recorded during the three months ended June 30, 2012 and 2011.

Fair Value Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” A three-tiered hierarchy for determining fair value has been established that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as Level 1 (unadjusted quoted prices for identical assets or liabilities in active markets), Level 2 (inputs that are observable in the marketplace other than those inputs classified in Level 1) and Level 3 (inputs that are unobservable in the marketplace). The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of its money market funds, securities available-for-sale portfolio and one foreign currency forward contract.

Allowance for Doubtful Accounts

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. 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.

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven 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

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.

Cash Provided as Collateral

Cash is provided as collateral for electronic bank settlements and broker-dealer clearance accounts. Cash provided as collateral is included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition.

Foreign Currency Translation and Forward Contracts

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the period; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are a component of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Transaction gains and losses are recorded in general and administrative expense in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to hedge its net investment in its U.K. subsidiary. Gains and losses on these transactions are included in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition.

9

Revenue Recognition

The majority of the Company’s revenues are derived from commissions for trades executed on its platform and distribution fees that are billed to its broker-dealer clients on a monthly basis. The Company also derives revenues from technology products and services, information and user access fees, investment income and other income.

Commission revenue. 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. For trades that the Company executes between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, the Company earns the commission through the difference in price between the two back-to-back trades. Fee programs for certain products include distribution fees which are recognized monthly.

Technology products and services. The Company generates revenues from technology software licenses, maintenance and support services (referred to as post-contract technical support or “PCS”) and professional consulting services. Revenue is generally recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection is considered probable. The Company generally sells software licenses and PCS together as part of multiple-element arrangements. The Company also enters into contracts for technology integration consulting services unrelated to any software product.

For arrangements that include multiple elements, generally software licenses and PCS, the Company allocates and defers revenue for the undelivered items based on vendor specific objective evidence (“VSOE”) of the fair value of the undelivered elements and recognizes the difference between the total arrangement fee and the amount deferred for the undelivered items as license revenue. The Company’s VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties or the stated renewal rate for the undelivered elements. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. For PCS, the term is typically one year and revenue is recognized over the duration of the arrangement on a straight-line basis.

Professional consulting services are generally separately priced and are typically not essential to the functionality of the Company’s software products. Revenues from these services are recognized separately from the license fee. Generally, revenue from time-and-materials consulting contracts is recognized as services are performed.

Revenues from contracts for technology integration consulting services are recognized on the percentage-of-completion method. Percentage-of-completion accounting involves calculating the percentage of services provided during the reporting period compared to the total estimated services to be provided over the duration of the contract. If estimates indicate that a contract loss will occur, a loss provision is recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. There were no contract loss provisions recorded as of June 30, 2012 and 2011. Revenues recognized in excess of billings are recorded as unbilled services within other assets. Billings in excess of revenues recognized are recorded as deferred revenues until revenue recognition criteria are met.

Initial set-up fees. 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 may pay an initial set-up fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial set-up fee, if any, varies by agreement. Revenue is recognized over the initial term of the agreement, which is generally two years.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital.

10

Income Taxes

Income taxes are accounted for using the asset and liability method. 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. The Company recognizes interest and penalties related to unrecognized tax benefits in general and administrative expenses in the Consolidated Statements of Operations.

Business Combinations, Goodwill and Intangible Assets

Business acquisitions are accounted for under the purchase method of accounting. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates and asset lives.

An impairment review of goodwill is performed on an annual basis and more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized on a straight-line basis over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average shares outstanding of common stock reflects the dilutive effect 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 U.S. generally accepted accounting principles 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 2011, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and there was no impact on the Company’s Consolidated Financial Statements.

In 2011, the FASB issued new disclosure guidance related to the presentation of the Statement of Comprehensive Income. This guidance eliminates the current option to report other comprehensive income and its components in the Consolidated Statement of Changes in Stockholders’ Equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the Consolidated Statement of Operations has been deferred. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and has presented a separate Statement of Comprehensive Income in the Company’s Consolidated Financial Statements.

The Company enters into foreign currency forward contracts to hedge the exposure to variability in foreign currency cash flows resulting from the net investment in the Company’s U.K. subsidiary. 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 period and are used to limit exposure to foreign currency exchange rate fluctuations. The gross and net fair value liability of $0.2 million as of June 30, 2012 is included in accounts payable and the gross and net fair value asset of $0.2 million as of December 31, 2011 is included in other assets in the Consolidated Statements of Financial Condition. Gains or losses on foreign currency forward contracts designated as hedges are included in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition.

Through December 31, 2010, the tax benefit on a portion of the tax deduction generated on the exercise of warrants in prior years had not yet been recorded. During the first quarter of 2011, the Company recognized the remaining portion of the tax benefit, amounting to $4.2 million, as an increase to additional paid-in-capital due to the expected utilization of the related tax loss carryforwards of $10.4 million.

The Company or one of its subsidiaries files U.S. federal, state and foreign income tax returns. No income tax returns have been audited, with the exception of New York city (through 2003) and state (through 2006) and Connecticut state (through 2003) tax returns. An examination of the Company’s New York state franchise tax returns for 2007 through 2009 is currently underway. The Company cannot estimate when the examination will conclude.

During the first quarter of 2011, the Company reached a settlement for a reimbursement claim on previously paid sales tax amounting to approximately $0.7 million. This amount has been reflected as a reduction of general and administrative expenses in the Consolidated Statements of Operations.

7. Related Party

9. Earnings Per Share

The following table sets forth the computation of basic and diluted earnings per common share.

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(In thousands, except per share amounts)
Net income	$	12,629	$	11,937	$	26,122	$	22,717
Common stock - voting		36,128		34,176		35,702		34,049
Common stock - non-voting		—		2,586		829		2,586
Basic weighted average shares outstanding		36,128		36,762		36,531		36,635
Basic earnings per share	$	0.35	$	0.32	$	0.72	$	0.62
Weighted average shares outstanding		36,128		36,762		36,531		36,635
Effect of dilutive shares:
Stock options and restricted stock		1,312		2,329		1,536		2,376
Warrants		—		399		—		385
Diluted weighted average shares outstanding		37,440		39,490		38,067		39,396
Diluted earnings per share	$	0.34	$	0.30	$	0.69	$	0.58

Stock options and restricted stock totaling zero and 0.3 million shares for the three months ended June 30, 2012 and 2011, respectively, and 0.2 million shares and 0.3 million shares for the six months ended June 30, 2012 and 2011, respectively, were excluded from the computation of diluted earnings per share because their effect would have been antidilutive. The computation of diluted shares can vary among periods due, in part, to the change in the average price of the Company’s common stock.

10. Commitments and Contingencies

The Company leases office space and equipment under non-cancelable lease agreements expiring at various dates through 2022. Office space leases are subject to escalation based on certain costs incurred by the landlord. Minimum rental commitments as of June 30, 2012 under such operating and capital leases were as follows:

	Operating Leases		Capital Leases
	(In thousands)
Remainder of 2012	$	904	$	168
2013		1,791		322
2014		1,757		42
2015		2,016		—
2016		2,029		—
2017 and thereafter		10,166		—
Minimum lease payments		18,663		532
Less amount representing interest		—		31
	$	18,663	$	501

Rental expense was $1.3 million and $1.2 million for the six months ended June 30, 2012 and 2011, respectively, and is included in occupancy expense 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. The Company is contingently obligated for standby letters of credit amounting to $1.7 million that were issued to landlords for office space.

17

In 2008, the Company assigned the lease agreement on a leased property to a third party. The Company is contingently liable should the assignee default on future lease obligations through the November 2015 lease termination date. The aggregate amount of future lease obligations under this arrangement was $1.2 million as of June 30, 2012.

The Company, through two regulated subsidiaries, executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which are then settled through a third-party clearing organization. The Company acts as intermediary on a riskless principal basis in these bond transactions by serving as counterparty to the two clients involved. 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. Under securities clearing agreements with the independent third party, the Company maintains a collateral deposit with the clearing broker in the form of cash. As of June 30, 2012, the amount of the collateral deposit included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition was $0.9 million. The Company is exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction. Pursuant to the terms of the securities clearing agreements between the Company and the independent clearing broker, the clearing broker has the right to charge the Company 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 June 30, 2012, the Company had not recorded any 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.

11. Customer Concentration

During both the six months ended June 30, 2012 and 2011, no single client accounted for more than 10% of total revenue. One client accounted for 13.9% and 15.7% of trading volumes during the six months ended June 30, 2012 and 2011, respectively.

12. Series B Preferred Stock Conversion

In 2008, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with two funds managed by Technology Crossover Ventures (the “Purchasers”), pursuant to which the Company sold to the Purchasers (i) 35,000 shares of the Company’s Series B Preferred Stock, which shares were convertible into an aggregate of 3,500,000 shares of common stock, and (ii) warrants (the “Warrants” and, together with the Series B Preferred Stock, the “Securities”) to purchase an aggregate of 700,000 shares of common stock at an exercise price of $10.00 per share, for an aggregate purchase price of $35.0 million. The net proceeds, after the placement agent fee and legal fees, were $33.5 million. The Warrants were exercisable for cash or on a net exercise basis. The Warrants were to expire on the tenth anniversary of the date they were first issued and were subject to customary anti-dilution adjustments in the event of stock splits, reverse stock splits, stock dividends and similar transactions.

The shares of Series B Preferred Stock were convertible at any time by the holders thereof at a conversion price of $10.00 per share, subject to certain anti-dilution adjustments and also were subject to automatic conversion into shares of common stock if the closing price of the common stock was at least $17.50 on each trading day for a period of 65 consecutive trading days. On January 24, 2011, all of the shares of the Series B Preferred Stock were mandatorily and automatically converted into 3,499,999 shares of common stock. In November 2011, a total of 455,465 shares of common stock were issued upon the exercise of the Warrants on a net exercise basis.

13. Share Repurchases

In October 2011, the Board of Directors authorized a share repurchase program for up to $35.0 million of the Company’s common stock. As of June 30, 2012, the Company repurchased 820,894 shares of common stock at a cost of $25.2 million. Shares repurchased under the program will be held in treasury for future use.

On February 28, 2012, the Company repurchased 1,821,730 shares of the Company’s non-voting common stock from the Stockholder Broker-Dealer Client at a cost of $52.9 million. Shares repurchased from the Stockholder Broker-Dealer Client were cancelled by the Company.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

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 the section captioned Part II, Item 1A, “Risk Factors.”

Executive Overview

MarketAxess operates a leading electronic trading platform that allows investment industry professionals to efficiently trade corporate bonds and other types of fixed-income instruments. Our over 900 active institutional investor clients (firms that executed at least one trade in U.S. or European fixed-income securities through our electronic trading platform between July 2011 and June 2012) include investment advisers, mutual funds, insurance companies, public and private pension funds, bank portfolios, broker-dealers and hedge funds. Our 87 broker-dealer market-maker clients provide liquidity on the platform and include most of the leading broker-dealers in global fixed-income trading. The Company also executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which then settle through a third-party clearing organization. Through our Corporate BondTicker™ service, we provide fixed-income market data, analytics and compliance tools that help our clients make trading decisions. In addition, we provide FIX (Financial Information eXchange) message management tools, connectivity solutions and ancillary technology services that facilitate the electronic communication of order information between trading counterparties. Our revenues are primarily generated from the trading of U.S. 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, asset-backed and preferred securities and credit default swaps.

The majority of our revenues are derived from commissions for trades executed on our platform and distribution fees that are billed to our broker-dealer clients on a monthly basis. We also derive revenues from technology products and services, information and user access 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, occupancy, marketing and advertising and other general and administrative expenses.

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 information, trading and technology services to market participants across the trading cycle. 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, deliver fixed-income securities-related technical services and products, and deploy our electronic trading platform into new client segments;

19

• 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 automated end-to-end straight-through processing solution (automation from trade initiation to settlement);

• to add new content and analytical capabilities to Corporate BondTicker™ 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.

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, among others, credit market conditions, 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, and consolidation or contraction of broker-dealers.

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. Sources of competition for us will continue to include, among others, bond trading conducted directly between broker-dealers and their institutional investor clients over the telephone or electronically and other multi-dealer trading companies. 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 platforms that may compete with us.

In general, we compete on the basis of a number of key factors, including, among others, the liquidity provided on our platform, the magnitude and frequency of price improvement enabled by our platform and the quality and speed of execution. We believe that our ability to grow volumes and revenues will largely depend on our performance with respect to these factors.

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.

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 FINRA. Our U.K. subsidiary, MarketAxess Europe Limited, is registered as a multilateral trading facility dealer with the FSA in the U.K. MarketAxess Canada Limited, a Canadian subsidiary, is registered as an Alternative Trading System dealer under the Securities Act of Ontario and is a member of the Investment Industry Regulatory Organization of Canada. Relevant 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.

20

In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was signed into law. U.S. financial regulators are in the midst of an intense period of rulemaking that is required to implement the provisions of the Dodd-Frank Act, and market participants will need to make strategic decisions in an environment of regulatory uncertainty. Among the most significant aspects of the derivatives section of the Dodd-Frank Act are mandatory clearing of certain derivatives transactions (“swaps”) through regulated central clearing organizations and mandatory trading of those swaps through either regulated exchanges or swap execution facilities, in each case, subject to certain key exceptions. As with other parts of the Dodd-Frank Act, many of the details of the new regulatory regime relating to swaps are left to the regulators to determine through rulemaking. While the U.S. Commodity Futures Trading Commission and SEC have adopted a number of rules that implement certain aspects of the new regulatory regime regarding the swaps market place, no assurance can be given regarding when, or whether, the remaining rules, including, among others, the rules regarding swap execution facilities and security-based swap execution facilities, will be finalized or implemented. Subject to such rulemaking, we currently expect to establish and operate a swap execution facility and/or a security-based swap execution facility.

The proposed Volcker Rule section of the Dodd-Frank Act bans proprietary trading by banks and their affiliates. The Volcker Rule could adversely affect our bank-affiliated broker-dealer clients’ ability to make markets in a variety of fixed-income securities, thereby negatively impacting the level of liquidity and pricing available on our trading platform. We cannot predict the extent to which any future regulatory changes may adversely affect our business and operations.

Similar to the U.S., regulatory bodies in Europe and elsewhere are developing new rules for derivatives trading. For example, the European Parliament and the EU Council of Ministers recently endorsed an agreement that will, among other things, require central clearing of standardized OTC derivatives and the reporting of all derivatives (OTC or otherwise) to trade repositories. However, it is not yet clear whether there will be any requirement in the EU to trade standardized derivative contracts on regulated exchanges or trading platforms.

Rapid Technological Changes

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. Our future success will depend on our ability to enhance our existing products and services, develop and/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. We have received a total of ten patents covering our most significant trading protocols and other aspects of our trading system technology and other patents are pending.

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 and monthly distribution fees. We believe that there are five key variables that impact the notional value of such transactions on our platform and the amount of commissions and distribution fees 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 frequency and competitiveness of the price responses 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.

21

Commission Revenue

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 and transaction costs through alternative channels including the telephone. 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 Bond Commissions. Our U.S. high-grade corporate bond fee plans for fully electronic trades generally incorporate variable transaction fees and distribution fees billed to our broker-dealer clients on a monthly basis. Certain dealers participate in fee programs that do not contain monthly distribution fees and instead incorporate additional per transaction execution fees and minimum monthly fee commitments. Under the fee plans, we electronically add the transaction fee to the spread quoted by the broker-dealer client.

Eurobond Commissions. Similar to the U.S. high-grade plans, our European fee plans generally incorporate monthly distribution fees as well as variable transaction fees. The variable transaction fee varies based on the type of bond traded.

Other Commissions. Commissions for other bond, asset-backed and preferred securities trades generally vary based on the type and the maturity of the instrument traded. We generally operate using standard fee schedules that may include both transaction fees and monthly distribution fees that are charged to the participating dealers.

For trades that we execute between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, we earn our commission through the difference in price between the two back-to-back trades.

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

Other Revenue

In addition to the commissions discussed above, we earn revenue from technology products and services, information services fees paid by institutional investor and broker-dealer clients, income on investments and other income.

Technology Products and Services. Technology products and services include software licenses, maintenance and support services and professional consulting services.

Information and User Access Fees. We charge information services fees for Corporate BondTicker^TM 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 platform, we reduce these information and user access fees for such clients once minimum quarterly trading volumes are attained.

Investment Income. Investment income consists of income earned on our investments.

Other. Other revenues include fees from telecommunications line charges to broker-dealer clients, initial set-up fees and other miscellaneous revenues.

Expenses

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-based compensation costs, other incentive compensation, employee benefits and payroll taxes.

22

Depreciation and Amortization. We depreciate our computer hardware and related software, office hardware and furniture and fixtures and amortize our capitalized software development costs on a straight-line basis over three to seven years. 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. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate a possible impairment.

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.

Occupancy. Occupancy costs consist primarily of office and equipment rent, utilities and commercial rent tax.

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.

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

Expenses may grow in the future, notably in employee compensation and benefits, primarily due to investment in new products and geographic expansion. However, 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 Estimates

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. There were no significant changes to our critical accounting policies and estimates during the three months ended June 30, 2012, as compared to those we disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2011.

Segment Results

As an electronic, multi-dealer platform for trading fixed-income securities, our operations constitute a single business segment. 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.

Results of Operations

Three Months Ended June 30, 2012 Compared to Three Months Ended June 30, 2011

Overview

Total revenues increased by $3.0 million or 6.6% to $48.8 million for the three months ended June 30, 2012, from $45.8 million for the three months ended June 30, 2011. This increase in total revenues was primarily due to an increase in commissions of $3.6 million, offset by a decrease in technology products and services of $0.8 million.

Total expenses increased by $1.7 million or 6.7% to $27.6 million for the three months ended June 30, 2012, from $25.9 million for the three months ended June 30, 2011. This increase was primarily due to higher marketing and advertising costs of $0.5 million, depreciation and amortization of $0.3 million and technology and communication costs of $0.3 million.

Income before taxes increased by $1.3 million or 6.5% to $21.2 million for the three months ended June 30, 2012, from $19.9 million for the three months ended June 30, 2011. Net income increased by $0.7 million or 5.8% to $12.6 million for the three months ended June 30, 2012, from $11.9 million for three months ended June 30, 2011.

Revenues

Our revenues for the three months ended June 30, 2012 and 2011, and the resulting dollar and percentage changes, were as follows:

U.S. high-grade distribution fees were $11.9 million for both the three months ended June 30, 2012 and June 30, 2011.

Due in part to the continuing sovereign debt concerns and the competitive environment in Europe, trading volume in our Eurobond product significantly decreased in 2011 and 2012. Monthly distribution fees paid by most of our European broker-dealer market makers were reduced effective March 1, 2012, but the dealer variable fee schedule remained unchanged. Several additional European broker-dealer market makers remain on the original fee plan and may move to the new fee plan in the future.

The following table shows the extent to which the increase in commissions for the three months ended June 30, 2012 was attributable to changes in transaction volumes, variable transaction fees per million and monthly distribution fees:

For volume reporting purposes, transactions in foreign currencies are converted to U.S. dollars at average monthly rates. The 12.1% increase in U.S. high-grade volume was principally due to an increase in the Company’s estimated market share of total U.S. high-grade corporate bond volume as reported by FINRA TRACE from 11.1% for the three months ended June 30, 2011 to 12.4% for the three months ended June 30, 2012. Estimated FINRA TRACE U.S. high-grade volume was up slightly to $731.4 billion for the three months ended June 30, 2012 from $729.8 billion for the three months ended June 30, 2011. Eurobond volumes decreased by 22.1% for the three months ended June 30, 2012 compared to the three months ended June 30, 2011 due, in part, to unfavorable market conditions in the European region. Other volume increased by 10.1% for the three months ended June 30, 2012 compared to the three months ended June 30, 2011, primarily due to higher emerging markets and high-yield bond volumes.

Our average variable transaction fee per million for the three months ended June 30, 2012 and 2011 was as follows:

	Three Months Ended June 30,
	2012		2011
Average Variable Transaction Fee Per Million
U.S. high-grade—fixed rate	$	208	$	192

Total U.S. high-grade		202		184
Eurobond		74		95
Other		205		182
Total		196		177

The U.S. high-grade average variable transaction fee per million increased from $184 for the three months ended June 30, 2011 to $202 for the three months ended June 30, 2012. The change was primarily due to an increase in the duration of bonds traded. Other average variable transaction fees per million increased from $182 for the three months ended June 30, 2011 to $205 for the three months ended June 30, 2012, primarily due to a larger percentage of Other volume in products that carry higher fees per million, principally emerging markets and high yield bonds.

Technology Products and Services. Technology products and services revenues decreased by $0.8 million or 19.2% to $3.2 million for the three months ended June 30, 2012, from $4.0 million for the three months ended June 30, 2011. The decrease was primarily a result of lower professional service fees.

Information and User Access Fees. Information and user access fees increased by $0.1 million or 4.1% to $1.8 million for the three months ended June 30, 2012, from $1.7 million for the three months ended June 30, 2011.

Investment Income. Investment income was $0.3 million for both the three months ended June 30, 2012 and 2011.

Other. Other revenues increased by $0.2 or 22.1% to $0.9 million for the three months ended June 30, 2012, from $0.7 million for the three months ended June 30, 2011.

Employee Compensation and Benefits. Employee compensation and benefits increased by $0.2 million or 1.3% to $15.3 million for the three months ended June 30, 2012, from $15.1 million for the three months ended June 30, 2011. This increase was primarily attributable to an increase in stock-based compensation expense of $1.3 million, offset by lower incentive compensation of $1.3 million. In conjunction with the June 2011 resignation of the Company’s President, unvested stock options, restricted stock and performance shares were canceled and the previously recorded expense amounting to $1.4 million was reversed.

Depreciation and Amortization. Depreciation and amortization increased by $0.3 million or 20.5% to $2.0 million for the three months ended June 30, 2012, from $1.6 million for the three months ended June 30, 2011. The increase is principally due to higher amortization of software development costs resulting from increased product development. For the three months ended June 30, 2012 and 2011, $0.4 million and $1.0 million, respectively, of leasehold improvements and equipment purchases and $1.3 million and $0.9 million, respectively, of software development costs were capitalized.

Technology and Communications. Technology and communications expenses increased by $0.3 million or 10.7% to $3.0 million for the three months ended June 30, 2012 from $2.7 million for the three months ended June 30, 2011. The increase was primarily attributable to higher market data and telecommunication fees.

Professional and Consulting Fees. Professional and consulting fees increased by $0.2 million or 6.5% to $2.8 million for the three months ended June 30, 2012, from $2.7 million for the three months ended June 30, 2011.

Occupancy. Occupancy costs were up slightly to $0.8 million for the three months ended June 30, 2012 from $0.7 for the three months ended June 30, 2011.

Marketing and Advertising. Marketing and advertising expenses increased by $0.5 million or 38.8% to $1.7 million for the three months ended June 30, 2012, from $1.2 million for the three months ended June 30, 2011. The increase was principally due to higher advertising and public relations costs associated with our credit default swaps trading capabilities.

General and Administrative. General and administrative expenses increased by $0.2 million or 11.5% to $2.0 million for the three months ended June 30, 2012, from $1.8 million for the three months ended June 30, 2011. The increase in general and administrative expenses was primarily attributable to a higher provision for doubtful accounts of $0.2 million.

Provision for Income Tax. For the three months ended June 30, 2012 and 2011, an income tax provision of $8.6 million and $8.0 million, respectively, were recorded. The increase in the tax provision was primarily attributable to the $1.3 million increase in pre-tax income for the period.

Our consolidated effective tax rate for the three months ended June 30, 2012 was 40.4%, compared to 40.0% for the three months ended June 30, 2011. Our consolidated effective tax rate can vary from period to period depending on, among other factors, the geographic and business mix of our earnings and changes in tax legislation and tax rates.

Six Months Ended June 30, 2012 Compared to Six Months Ended June 30, 2011

Overview

Total revenues increased by $10.2 million or 11.4% to $99.6 million for the six months ended June 30, 2012, from $89.4 million for the six months ended June 30, 2011. This increase in total revenues was primarily due to an increase in commissions of $10.7 million, offset by a decrease in technology products and services of $1.0 million.

Total expenses increased by $3.8 million or 7.3% to $55.6 million for the six months ended June 30, 2012, from $51.8 million for the six months ended June 30, 2011. This increase was primarily due to higher general and administrative expense of $1.3 million, marketing and advertising costs of $1.0 million, technology and communication costs of $0.7 million and depreciation and amortization of $0.6 million.

Income before taxes increased by $6.4 million or 17.0% to $43.9 million for the six months ended June 30, 2012, from $37.6 million for the six months ended June 30, 2011. Net income increased by $3.0 million or 15.0% to $26.1 million for the six months ended June 30, 2012, from $22.7 million for six months ended June 30, 2011.

U.S. high-grade distribution fees increased by $1.5 million for the six months ended June 30, 2012 compared to the six months ended June 30, 2011 principally due to the migration of several broker-dealer market makers from an all-variable plan to a plan that incorporates a combination of a monthly distribution fee and variable transaction fees.

Eurobond distribution fees decreased by $1.9 million for the six months ended June 30, 2012 compared to the six months ended June 30, 2011 principally due to the reduction in monthly distribution fees paid by most of our European broker-dealer market makers effective March 1, 2012.

The following table shows the extent to which the increase in commissions for the six months ended June 30, 2012 was attributable to changes in transaction volumes, variable transaction fees per million and monthly distribution fees:

For volume reporting purposes, transactions in foreign currencies are converted to U.S. dollars at average monthly rates. The 13.8% increase in U.S. high-grade volume was principally due to an increase in the Company’s estimated market share of total U.S. high-grade corporate bond volume as reported by FINRA TRACE from 10.4% for the six months ended June 30, 2011 to 11.8% for the six months ended June 30, 2012. Estimated FINRA TRACE U.S. high-grade volume was up slightly to $1.60 trillion for the six months ended June 30, 2012 from $1.59 trillion for the six months ended June 30, 2011. Eurobond volumes decreased by 3.7% for the six months ended June 30, 2012 compared to the six months ended June 30, 2011 due, in part, to unfavorable market conditions in the European region. Other volume increased by 15.5% for the six months ended June 30, 2012 compared to the six months ended June 30, 2011, primarily due to higher emerging markets and high-yield bond volumes.

Our average variable transaction fee per million for the six months ended June 30, 2012 and 2011 was as follows:

	Six Months Ended June 30,
	2012		2011
Average Variable Transaction Fee Per Million
U.S. high-grade—fixed rate	$	201	$	185
U.S. high-grade—floating rate		26		20
Total U.S. high-grade		195		178
Eurobond		69		98
Other		204		179
Total		189		172

29

The U.S. high-grade average variable transaction fee per million increased from $178 for the six months ended June 30, 2011 to $195 for the six months ended June 30, 2012. The change was primarily due to an increase in the duration of bonds traded. The Eurobond average variable transaction fee per million decreased from $98 for the six months ended June 30, 2011 to $69 for the six months ended June 30, 2012. During the first quarter of 2012, the monthly distribution fees paid by most European broker-dealer market makers were reduced. In connection with this change, variable fees for Eurobond credit trading were waived for one-month prior to the implementation of the new distribution fee plan. Other average variable transaction fees per million increased from $179 for the six months ended June 30, 2011 to $204 for the six months ended June 30, 2012, primarily due to a larger percentage of Other volume in products that carry higher fees per million, principally emerging markets and high yield bonds.

Technology Products and Services. Technology products and services revenues decreased by $1.0 million or 13.6% to $6.1 million for the six months ended June 30, 2012, from $7.1 million for the six months ended June 30, 2011. The decrease was primarily a result of lower professional consulting and software license fees.

Information and User Access Fees. Information and user access fees increased by $0.3 million or 7.4% to $3.7 million for the six months ended June 30, 2012, from $3.4 million for the six months ended June 30, 2011.

Investment Income. Investment income was $0.6 million for both the six months ended June 30, 2012 and 2011.

Other. Other revenues increased by $0.2 million or 12.4% to $1.6 million for the six months ended June 30, 2012, from $1.4 million for the six months ended June 30, 2011.

Expenses

Our expenses for the six months ended June 30, 2012 and 2011, and the resulting dollar and percentage changes were as follows:

Total expenses	$	55,612		55.9	%	$	51,829		58.0	%	$	3,783			7.3	%

Employee Compensation and Benefits. Employee compensation and benefits decreased by $0.2 million or 0.7% to $31.1 million for the six months ended June 30, 2012, from $31.4 million for the six months ended June 30, 2011. The decrease was primarily attributable to lower incentive compensation of $1.5 million, offset by an increase in stock-based compensation expense of $1.0 million. In conjunction with the June 2011 resignation of the Company’s President, unvested stock options, restricted stock and performance shares were canceled and the previously recorded expense amounting to $1.4 million was reversed.

Depreciation and Amortization. Depreciation and amortization increased by $0.6 million or 19.6% to $3.8 million for the six months ended June 30, 2012, from $3.2 million for the six months ended June 30, 2011. The increase is principally due to higher amortization of software development costs resulting from increased product development. For the six months ended June 30, 2012 and 2011, $1.0 million and $1.5 million, respectively, of leasehold improvements and equipment purchases and $2.6 million and $1.8 million, respectively, of software development costs were capitalized.

Technology and Communications. Technology and communications expenses increased by $0.7 million or 14.3% to $6.0 million for the six months ended June 30, 2012 from $5.2 million for the six months ended June 30, 2011. The increase was primarily attributable to higher market data and telecommunications fees.

30

Professional and Consulting Fees. Professional and consulting fees increased by $0.3 million or 5.9% to $5.9 million for the six months ended June 30, 2012, from $5.5 million for the six months ended June 30, 2011. The increase was primarily due to costs associated with the registered underwritten secondary public offering of 3,597,333 shares of common stock held by JPM.

Occupancy. Occupancy costs were $1.5 million for both the six months ended June 30, 2012 and 2011.

Marketing and Advertising. Marketing and advertising expenses increased by $1.0 million or 43.1% to $3.2 million for the six months ended June 30, 2012, from $2.2 million for the six months ended June 30, 2011. The increase was principally due to higher advertising and public relations costs associated with our credit default swaps trading capabilities.

General and Administrative. General and administrative expenses increased by $1.3 million or 46.7% to $4.1 million for the six months ended June 30, 2012, from $2.8 million for the six months ended June 30, 2011. During the first quarter of 2011, the Company received a $0.7 million reimbursement of previously paid sales tax. The increase in general and administrative expenses was primarily attributable to the 2011 sales tax credit coupled with a higher provision for doubtful accounts of $0.6 million.

Provision for Income Tax. For the six months ended June 30, 2012 and 2011, an income tax provision of $17.8 million and $14.9 million, respectively, were recorded. The increase in the tax provision was primarily attributable to the $6.4 million increase in pre-tax income for the period.

Our consolidated effective tax rate for the six months ended June 30, 2012 was 40.6%, compared to 39.5% for the six months ended June 30, 2011, primarily due to a decline in income from foreign operations. Our consolidated effective tax rate can vary from period to period depending on, among other factors, the geographic and business mix of our earnings and changes in tax legislation and tax rates.

Liquidity and Capital Resources

During the past three years, we have met our cash needs through cash on hand and internally generated funds. Cash and cash equivalents and securities available-for-sale totaled $188.2 million at June 30, 2012. Other than equipment-related capital lease obligations amounting to $0.5 million as of June 30, 2012, we have no long-term or short-term debt and do not maintain bank lines of credit.

Our cash flows were as follows:

	Six Months Ended June 30,
	2012			2011
	(In thousands)
Net cash provided by operating activities	$	25,895		$	19,409
Net cash provided by (used in) investing activities		15,013			(6,014	)
Net cash (used in) financing activities		(80,465	)		(2,084	)
Effect of exchange rate changes on cash and cash equivalents		(468	)		(537	)
Net (decrease) increase for the period	$	(40,025	)	$	10,774

Free cash flow is defined as cash flow from operating activities less expenditures for furniture, equipment and leasehold improvements and capitalized software development costs. For the 12 months ended June 30, 2012 and 2011, free cash flow was $64.4 million and $55.2 million, respectively. Free cash flow is a non-GAAP financial measure. We believe that this non-GAAP financial measure, when taken into consideration with the corresponding GAAP financial measures, is important in gaining an understanding of the Company’s financial strength and cash flow generation.

Net cash provided by operating activities was $25.9 million for the six months ended June 30, 2012 compared to $19.4 million for the six months ended June 30, 2011. The $6.5 million increase in net cash provided by operating activities was primarily due to an increase in net income of $3.4 million and a decrease in cash used for working capital of $7.6 million, offset by lower non-cash deferred income taxes of $7.2 million. During the six months ended June 30, 2012, annual year-end bonus payments were $18.2 million compared to $16.7 million for the six months ended June 30, 2011. The balance of our unrestricted U.S. net operating loss carryforward was fully utilized during 2011, which will result in an increase in cash paid for income taxes in 2012. During the six months ended June 30, 2012, cash paid for income taxes was $6.9 million compared to $6.0 million for the six months ended June 30, 2011.

31

Net cash provided by investing activities was $15.0 million for the six months ended June 30, 2012 compared to net cash used in investing activities of $6.0 million for the six months ended June 30, 2011. Net proceeds of securities available-for-sale were $18.6 million for the six months ended June 30, 2012 compared to net purchases of $2.7 million for the six months ended June 30, 2011. Capital expenditures were $3.6 million and $3.3 million for the six months ended June 30, 2012 and 2011, respectively.

Net cash used in financing activities was $80.5 million for the six months ended June 30, 2012 compared to net cash provided by financing activities of $2.1 million for the six months ended June 30, 2011. The $78.4 million increase in net cash used in financing activities was principally due to repurchases of the Company’s common stock of $71.1 million, an increase in withholding tax payments on restricted stock vesting and stock option exercises of $15.7 million and an increase of $1.5 million in cash dividends paid in 2012 on common stock, offset by an increase in excess tax benefits from stock-based compensation of $10.7 million.

Past trends of cash flows are not necessarily indicative of future cash flow levels. A decrease in cash flows may have a material adverse effect on our liquidity, business and financial condition.

Other Factors Influencing Liquidity and Capital Resources

We are dependent on our broker-dealer clients, who are not restricted from buying and selling fixed-income securities with institutional investors, either directly or through their own proprietary or third-party platforms. 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 addition, we fully utilized the balance of our unrestricted U.S. net operating loss carryforward during 2011, which will result in an increase in cash paid for income taxes in 2012 and subsequent years. 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, if available at all, may involve restrictive covenants with respect to dividends, issuances of additional capital and other financial and operational matters related to our business.

We have three regulated subsidiaries, MarketAxess Corporation, MarketAxess Europe Limited and MarketAxess Canada Ltd. MarketAxess Corporation is a registered broker-dealer in the U.S., MarketAxess Europe Limited is a registered multilateral trading facility in the U.K. and MarketAxess Canada Ltd. is a registered Alternative Trading System in the Province of Ontario. 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 relevant 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. Subject to rulemaking pursuant to the Dodd-Frank Act, we currently expect to establish and operate a swap execution facility and/or a security-based swap execution facility and we will be required to maintain an additional amount of minimum net capital in connection with such facilities. The following table sets forth the capital requirements, as defined, that the Company’s subsidiaries were required to maintain as of June 30, 2012:

	MarketAxess		MarketAxess		MarketAxess
	Corporation		Europe Limited		Canada Limited
	(In thousands)
Net capital	$	66,293	$	28,001	$	406
Minimum net capital required		1,619		3,212		271
Excess net capital	$	64,674	$	24,789	$	135

32

We execute certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which are then settled through a third-party clearing organization. We act as intermediary on a riskless principal basis in these bond transactions by serving as counterparty to the two clients involved. 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. Under securities clearing agreements with the independent third party, we maintain collateral deposits with the clearing broker in the form of cash. As of June 30, 2012, the amount of the collateral deposits included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition were $0.9 million. We are exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction. Pursuant to the terms of the securities clearing agreements between us and the independent clearing broker, the clearing broker has the right to charge us 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 June 30, 2012, we have not recorded any 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.

We continue to return capital to our shareholders through dividends and share repurchases. In October 2011, the Board of Directors authorized a share repurchase program for up to $35.0 million of the Company’s common stock. As of June 30, 2012, the Company repurchased 820,894 shares of common stock at a cost of $25.2 million. Shares repurchased under the program will be held in treasury for future use.

In October 2009, our Board of Directors approved our first regular quarterly dividend. The quarterly cash dividend was increased to $0.11 per share in the first quarter of 2012. In July 2012, our Board of Directors approved a quarterly cash dividend of $0.11 per share, which will be paid on August 23, 2012 to stockholders of record as of the close of business on August 9, 2012. We expect the total amount payable to be approximately $4.1 million. We expect to continue paying regular cash dividends, although there is no assurance as to such dividends. Any future declaration and payment of dividends will be at the sole discretion of our Board of Directors.

Effects of Inflation

Because the majority of our assets are short-term 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 condition and results of operations.

Contractual Obligations and Commitments

There was no significant change in our contractual obligations and commitments for the six months ended June 30, 2012.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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

Market Risk

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 and revenues. These events could have a material adverse effect on our business, financial condition and results of operations.

As of June 30, 2012, we had a $58.6 million investment in securities available-for-sale. Adverse movements, such as a 10% decrease in the value of these securities or a downturn or disruption in the markets for these securities, could result in a substantial loss. In addition, principal gains and losses resulting from these securities could on occasion have a disproportionate effect, positive or negative, on our financial condition and results of operations for any particular reporting period.

33

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 fixed-income securities in which we invest. As of June 30, 2012, our cash and cash equivalents and securities available-for-sale amounted to $188.2 million and were primarily in money market instruments, U.S. government obligations and municipal securities. 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. subsidiary. As of June 30, 2012, the notional fair value of our foreign currency forward contract was $28.5 million. We do not speculate in any derivative instruments.

Credit Risk

We act as a riskless principal through two of our regulated subsidiaries in certain transactions that we execute between clients. We act as an intermediary in these transactions by serving as counterparty to both the buyer and the seller in matching back-to-back bond 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 clients. 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. There can be no assurance that these policies and procedures will effectively mitigate our credit risk exposure.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. Our management, including the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our “disclosure controls and procedures” as that term is defined in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of June 30, 2012. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective to ensure that information required to be disclosed by MarketAxess in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and to ensure that information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control Over Financial Reporting. There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2012 identified in connection with the evaluation thereof by our management, including the Chief Executive Officer and Chief Financial Officer, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting

Item 1A. Risk Factors

Risks that could have a negative impact on our business, results of operations and financial condition include: the level and intensity of competition in the fixed-income electronic trading industry and the pricing pressures that may result; the variability of our growth rate; the rapidly evolving nature of the electronic financial services industry; the level of trading volume transacted on the MarketAxess platform; potential fluctuations in our operating results, which may cause our stock price to decline; the absolute level and direction of interest rates and the corresponding volatility in the corporate fixed-income market; our ability to develop new products and offerings and the market’s acceptance of those products; our exposure to risk resulting from non-performance by counterparties to transactions executed between our clients in which we act as an intermediary in matching back-to-back trades; our dependence on our broker-dealer clients and institutional investor clients; technology failures, security breaches or rapid technology changes that may harm our business; our ability to enter into strategic alliances and to acquire other businesses and successfully integrate them with our business; extensive government regulation; continuing international expansion that may present economic and regulatory challenges; and our future capital needs and our ability to obtain capital when needed. This list is intended to identify only certain of the principal factors that could have a material adverse impact on our business, results of operations and financial condition. A more detailed description of each of these and other important risk factors can be found under the caption “Risk Factors” in our most recent Form 10-K for the year ended December 31, 2011. There have been no material changes to the risk factors described in such Form 10-K.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

2. Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated. These consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. The consolidated financial information as of December 31, 2011 has been derived from audited financial statements not included herein.

These unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) with respect to Form 10-Q and reflect all adjustments that, in the opinion of management, are normal and recurring, and that are necessary for a fair statement of the results for the interim periods presented. In accordance with such rules and regulations, certain disclosures that are normally included in annual financial statements have been omitted. Interim period operating results may not be indicative of the operating results for a full year.

Cash and Cash Equivalents

Cash and cash equivalents includes cash and money market instruments that are primarily maintained at one major global bank. Given this concentration, the Company is exposed to certain credit risk. The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Securities Available-for-Sale

The Company classifies its marketable securities as available-for-sale securities. Unrealized marketable securities gains and losses, net of taxes, are reflected as a net amount under the caption of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Realized gains and losses are recorded in the Consolidated Statements of Operations in other revenues. For the purpose of computing realized gains and losses, cost is determined on a specific identification basis.

The Company assesses whether an other-than-temporary impairment loss on the investments has occurred due to declines in fair value or other market conditions. The portion of an other-than-temporary impairment related to credit loss is recorded as a charge in the Consolidated Statements of Operations. The remainder is recognized in accumulated other comprehensive loss if the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security prior to recovery. No charges for other-than-temporary losses were recorded during the three months ended June 30, 2012 and 2011.

Fair Value Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” A three-tiered hierarchy for determining fair value has been established that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as Level 1 (unadjusted quoted prices for identical assets or liabilities in active markets), Level 2 (inputs that are observable in the marketplace other than those inputs classified in Level 1) and Level 3 (inputs that are unobservable in the marketplace). The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of its money market funds, securities available-for-sale portfolio and one foreign currency forward contract.

Allowance for Doubtful Accounts

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. 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.

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven 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

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.

Cash Provided as Collateral

Cash is provided as collateral for electronic bank settlements and broker-dealer clearance accounts. Cash provided as collateral is included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition.

Foreign Currency Translation and Forward Contracts

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the period; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are a component of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Transaction gains and losses are recorded in general and administrative expense in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to hedge its net investment in its U.K. subsidiary. Gains and losses on these transactions are included in accumulated other comprehensive loss in 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 and distribution fees that are billed to its broker-dealer clients on a monthly basis. The Company also derives revenues from technology products and services, information and user access fees, investment income and other income.

Commission revenue. 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. For trades that the Company executes between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, the Company earns the commission through the difference in price between the two back-to-back trades. Fee programs for certain products include distribution fees which are recognized monthly.

Technology products and services. The Company generates revenues from technology software licenses, maintenance and support services (referred to as post-contract technical support or “PCS”) and professional consulting services. Revenue is generally recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection is considered probable. The Company generally sells software licenses and PCS together as part of multiple-element arrangements. The Company also enters into contracts for technology integration consulting services unrelated to any software product.

For arrangements that include multiple elements, generally software licenses and PCS, the Company allocates and defers revenue for the undelivered items based on vendor specific objective evidence (“VSOE”) of the fair value of the undelivered elements and recognizes the difference between the total arrangement fee and the amount deferred for the undelivered items as license revenue. The Company’s VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties or the stated renewal rate for the undelivered elements. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. For PCS, the term is typically one year and revenue is recognized over the duration of the arrangement on a straight-line basis.

Professional consulting services are generally separately priced and are typically not essential to the functionality of the Company’s software products. Revenues from these services are recognized separately from the license fee. Generally, revenue from time-and-materials consulting contracts is recognized as services are performed.

Revenues from contracts for technology integration consulting services are recognized on the percentage-of-completion method. Percentage-of-completion accounting involves calculating the percentage of services provided during the reporting period compared to the total estimated services to be provided over the duration of the contract. If estimates indicate that a contract loss will occur, a loss provision is recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. There were no contract loss provisions recorded as of June 30, 2012 and 2011. Revenues recognized in excess of billings are recorded as unbilled services within other assets. Billings in excess of revenues recognized are recorded as deferred revenues until revenue recognition criteria are met.

Initial set-up fees. 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 may pay an initial set-up fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial set-up fee, if any, varies by agreement. Revenue is recognized over the initial term of the agreement, which is generally two years.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital.

Income Taxes

Income taxes are accounted for using the asset and liability method. 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. The Company recognizes interest and penalties related to unrecognized tax benefits in general and administrative expenses in the Consolidated Statements of Operations.

Business Combinations, Goodwill and Intangible Assets

Business acquisitions are accounted for under the purchase method of accounting. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates and asset lives.

An impairment review of goodwill is performed on an annual basis and more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized on a straight-line basis over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average shares outstanding of common stock reflects the dilutive effect 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 U.S. generally accepted accounting principles 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.

In 2011, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and there was no impact on the Company’s Consolidated Financial Statements.

In 2011, the FASB issued new disclosure guidance related to the presentation of the Statement of Comprehensive Income. This guidance eliminates the current option to report other comprehensive income and its components in the Consolidated Statement of Changes in Stockholders’ Equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the Consolidated Statement of Operations has been deferred. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and has presented a separate Statement of Comprehensive Income in the Company’s Consolidated Financial Statements.

Organization and Principal Business Activity

1. Organization and Principal Business Activity

MarketAxess Holdings Inc. (the “Company” or “MarketAxess”) 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 other types of fixed-income instruments through which the Company’s 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 and asset-backed and preferred securities. The Company also executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which then settle through a third-party clearing organization. Through its Corporate BondTicker™ service, the Company provides fixed-income market data, analytics and compliance tools that help its clients make trading decisions. In addition, the Company provides FIX (Financial Information eXchange) message management tools, connectivity solutions and ancillary technology services that facilitate the electronic communication of order information between trading counterparties.

For 2011, JPMorgan Chase & Co. (“JPM”) was the Company’s sole stockholder broker-dealer client (the “Stockholder Broker-Dealer Client”). During the first quarter of 2012, JPM sold its shares of the Company’s common stock and is no longer considered a related party. See Note 7, “Related Party” and Note 13, “Share Repurchases.”

Commitments and Contingencies

10. Commitments and Contingencies

The Company leases office space and equipment under non-cancelable lease agreements expiring at various dates through 2022. Office space leases are subject to escalation based on certain costs incurred by the landlord. Minimum rental commitments as of June 30, 2012 under such operating and capital leases were as follows:

	Operating Leases		Capital Leases
	(In thousands)
Remainder of 2012	$	904	$	168

Minimum lease payments		18,663		532
Less amount representing interest		—		31
	$	18,663	$	501

Rental expense was $1.3 million and $1.2 million for the six months ended June 30, 2012 and 2011, respectively, and is included in occupancy expense 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. The Company is contingently obligated for standby letters of credit amounting to $1.7 million that were issued to landlords for office space.

In 2008, the Company assigned the lease agreement on a leased property to a third party. The Company is contingently liable should the assignee default on future lease obligations through the November 2015 lease termination date. The aggregate amount of future lease obligations under this arrangement was $1.2 million as of June 30, 2012.

The Company, through two regulated subsidiaries, executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which are then settled through a third-party clearing organization. The Company acts as intermediary on a riskless principal basis in these bond transactions by serving as counterparty to the two clients involved. 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. Under securities clearing agreements with the independent third party, the Company maintains a collateral deposit with the clearing broker in the form of cash. As of June 30, 2012, the amount of the collateral deposit included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition was $0.9 million. The Company is exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction. Pursuant to the terms of the securities clearing agreements between the Company and the independent clearing broker, the clearing broker has the right to charge the Company 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 June 30, 2012, the Company had not recorded any 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.

	$	111,256	$	78,265		$	—	$	189,521

Securities classified within Level 2 were valued using a market approach utilizing prices and other relevant information generated by market transactions involving comparable assets. The foreign currency forward contract is classified within Level 2 as the valuation inputs are based on quoted market prices. There were no financial assets classified within Level 3 during 2012 and 2011.

The Company enters into foreign currency forward contracts to hedge the exposure to variability in foreign currency cash flows resulting from the net investment in the Company’s U.K. subsidiary. 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 period and are used to limit exposure to foreign currency exchange rate fluctuations. The gross and net fair value liability of $0.2 million as of June 30, 2012 is included in accounts payable and the gross and net fair value asset of $0.2 million as of December 31, 2011 is included in other assets in the Consolidated Statements of Financial Condition. Gains or losses on foreign currency forward contracts designated as hedges are included in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. A summary of the foreign currency forward contracts is as follows:

Series B Preferred Stock Conversion [Abstract]

Series B Preferred Stock Conversion

12. Series B Preferred Stock Conversion

In 2008, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with two funds managed by Technology Crossover Ventures (the “Purchasers”), pursuant to which the Company sold to the Purchasers (i) 35,000 shares of the Company’s Series B Preferred Stock, which shares were convertible into an aggregate of 3,500,000 shares of common stock, and (ii) warrants (the “Warrants” and, together with the Series B Preferred Stock, the “Securities”) to purchase an aggregate of 700,000 shares of common stock at an exercise price of $10.00 per share, for an aggregate purchase price of $35.0 million. The net proceeds, after the placement agent fee and legal fees, were $33.5 million. The Warrants were exercisable for cash or on a net exercise basis. The Warrants were to expire on the tenth anniversary of the date they were first issued and were subject to customary anti-dilution adjustments in the event of stock splits, reverse stock splits, stock dividends and similar transactions.

The shares of Series B Preferred Stock were convertible at any time by the holders thereof at a conversion price of $10.00 per share, subject to certain anti-dilution adjustments and also were subject to automatic conversion into shares of common stock if the closing price of the common stock was at least $17.50 on each trading day for a period of 65 consecutive trading days. On January 24, 2011, all of the shares of the Series B Preferred Stock were mandatorily and automatically converted into 3,499,999 shares of common stock. In November 2011, a total of 455,465 shares of common stock were issued upon the exercise of the Warrants on a net exercise basis.

The Company records stock-based compensation for employees in employee compensation and benefits and for non-employee directors in general and administrative expenses in the Consolidated Statements of Operations. In conjunction with the June 2011 resignation of the Company’s President, unvested stock options, restricted stock and performance shares were canceled and the previously recorded expense amounting to $1.4 million was reversed.

During the six months ended June 30, 2012, the Company granted to employees a total of 183,988 shares of restricted stock or restricted stock units, performance-based shares with an expected pay-out at target of 44,843 shares of common stock and 375 options to purchase shares of common stock. The fair value of the restricted stock and performance-based share awards was based on a weighted-average grant date fair value per share of $31.03 and $30.64, respectively. Based on the Black-Scholes option pricing model, the weighted-average fair value for each option granted was $11.99 per share. As of June 30, 2012, the total unrecognized compensation costs related to non-vested awards was $15.2 million. That cost is expected to be recognized over a weighted-average period of 2.4 years.

Through December 31, 2010, the tax benefit on a portion of the tax deduction generated on the exercise of warrants in prior years had not yet been recorded. During the first quarter of 2011, the Company recognized the remaining portion of the tax benefit, amounting to $4.2 million, as an increase to additional paid-in-capital due to the expected utilization of the related tax loss carryforwards of $10.4 million.

The Company or one of its subsidiaries files U.S. federal, state and foreign income tax returns. No income tax returns have been audited, with the exception of New York city (through 2003) and state (through 2006) and Connecticut state (through 2003) tax returns. An examination of the Company’s New York state franchise tax returns for 2007 through 2009 is currently underway. The Company cannot estimate when the examination will conclude.

During the first quarter of 2011, the Company reached a settlement for a reimbursement claim on previously paid sales tax amounting to approximately $0.7 million. This amount has been reflected as a reduction of general and administrative expenses in the Consolidated Statements of Operations.

The computation of diluted shares can vary among periods due, in part, to the change in the average price of the Company’s common stock.

These consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. The consolidated financial information as of December 31, 2011 has been derived from audited financial statements not included herein.

These unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) with respect to Form 10-Q and reflect all adjustments that, in the opinion of management, are normal and recurring, and that are necessary for a fair statement of the results for the interim periods presented. In accordance with such rules and regulations, certain disclosures that are normally included in annual financial statements have been omitted. Interim period operating results may not be indicative of the operating results for a full year.

Cash and cash equivalents

Cash and Cash Equivalents

Cash and cash equivalents includes cash and money market instruments that are primarily maintained at one major global bank. Given this concentration, the Company is exposed to certain credit risk. The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Securities available-for-sale

Securities Available-for-Sale

The Company classifies its marketable securities as available-for-sale securities. Unrealized marketable securities gains and losses, net of taxes, are reflected as a net amount under the caption of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Realized gains and losses are recorded in the Consolidated Statements of Operations in other revenues. For the purpose of computing realized gains and losses, cost is determined on a specific identification basis.

The Company assesses whether an other-than-temporary impairment loss on the investments has occurred due to declines in fair value or other market conditions. The portion of an other-than-temporary impairment related to credit loss is recorded as a charge in the Consolidated Statements of Operations. The remainder is recognized in accumulated other comprehensive loss if the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security prior to recovery. No charges for other-than-temporary losses were recorded during the three months ended June 30, 2012 and 2011.

Fair value financial instruments

Fair Value Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” A three-tiered hierarchy for determining fair value has been established that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as Level 1 (unadjusted quoted prices for identical assets or liabilities in active markets), Level 2 (inputs that are observable in the marketplace other than those inputs classified in Level 1) and Level 3 (inputs that are unobservable in the marketplace). The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of its money market funds, securities available-for-sale portfolio and one foreign currency forward contract.

Allowance for doubtful accounts

Allowance for Doubtful Accounts

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. 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.

Depreciation and amortization

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven 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

Software Development Costs

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.

Cash provided as collateral

Cash Provided as Collateral

Cash is provided as collateral for electronic bank settlements and broker-dealer clearance accounts. Cash provided as collateral is included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition.

Foreign currency translation and forward contracts

Foreign Currency Translation and Forward Contracts

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the period; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are a component of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Transaction gains and losses are recorded in general and administrative expense in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to hedge its net investment in its U.K. subsidiary. Gains and losses on these transactions are included in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition.

Revenue recognition

Revenue Recognition

The majority of the Company’s revenues are derived from commissions for trades executed on its platform and distribution fees that are billed to its broker-dealer clients on a monthly basis. The Company also derives revenues from technology products and services, information and user access fees, investment income and other income.

Commission revenue. 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. For trades that the Company executes between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, the Company earns the commission through the difference in price between the two back-to-back trades. Fee programs for certain products include distribution fees which are recognized monthly.

Technology products and services. The Company generates revenues from technology software licenses, maintenance and support services (referred to as post-contract technical support or “PCS”) and professional consulting services. Revenue is generally recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection is considered probable. The Company generally sells software licenses and PCS together as part of multiple-element arrangements. The Company also enters into contracts for technology integration consulting services unrelated to any software product.

For arrangements that include multiple elements, generally software licenses and PCS, the Company allocates and defers revenue for the undelivered items based on vendor specific objective evidence (“VSOE”) of the fair value of the undelivered elements and recognizes the difference between the total arrangement fee and the amount deferred for the undelivered items as license revenue. The Company’s VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties or the stated renewal rate for the undelivered elements. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. For PCS, the term is typically one year and revenue is recognized over the duration of the arrangement on a straight-line basis.

Professional consulting services are generally separately priced and are typically not essential to the functionality of the Company’s software products. Revenues from these services are recognized separately from the license fee. Generally, revenue from time-and-materials consulting contracts is recognized as services are performed.

Revenues from contracts for technology integration consulting services are recognized on the percentage-of-completion method. Percentage-of-completion accounting involves calculating the percentage of services provided during the reporting period compared to the total estimated services to be provided over the duration of the contract. If estimates indicate that a contract loss will occur, a loss provision is recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. There were no contract loss provisions recorded as of June 30, 2012 and 2011. Revenues recognized in excess of billings are recorded as unbilled services within other assets. Billings in excess of revenues recognized are recorded as deferred revenues until revenue recognition criteria are met.

Initial set-up fees. 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 may pay an initial set-up fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial set-up fee, if any, varies by agreement. Revenue is recognized over the initial term of the agreement, which is generally two years.

Stock-based compensation

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital.

Income taxes

Income Taxes

Income taxes are accounted for using the asset and liability method. 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. The Company recognizes interest and penalties related to unrecognized tax benefits in general and administrative expenses in the Consolidated Statements of Operations.

Business combinations, goodwill and intangible assets

Business Combinations, Goodwill and Intangible Assets

Business acquisitions are accounted for under the purchase method of accounting. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates and asset lives.

An impairment review of goodwill is performed on an annual basis and more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized on a straight-line basis over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Earnings per share

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average shares outstanding of common stock reflects the dilutive effect that could occur if convertible securities or other contracts to issue common stock were converted into or exercised for common stock.

Use of estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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

Recent Accounting Pronouncements

In 2011, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and there was no impact on the Company’s Consolidated Financial Statements.

In 2011, the FASB issued new disclosure guidance related to the presentation of the Statement of Comprehensive Income. This guidance eliminates the current option to report other comprehensive income and its components in the Consolidated Statement of Changes in Stockholders’ Equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the Consolidated Statement of Operations has been deferred. This accounting standard is effective for fiscal years beginning on or after December 15, 2011. The Company adopted the new guidance effective January 1, 2012 and has presented a separate Statement of Comprehensive Income in the Company’s Consolidated Financial Statements.
