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, 2022. The consolidated financial information as of December 31, 2022 has been derived from audited financial statements not included herein. These unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) 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

The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Investments

The Company determines the appropriate classification of securities at the time of purchase which are recorded in the Consolidated Statements of Financial Condition on the trade date. Securities are classified as available-for-sale or trading. Available-for-sale investments are carried at fair value with unrealized gains or losses reported in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition and realized gains or losses reported in other, net in the Consolidated Statements of Operations. Trading investments include U.S. Treasuries and are carried at fair value, with realized and unrealized gains or losses included in other, net in the Consolidated Statements of Operations.

The Company assesses whether an impairment loss on its available-for-sale debt securities has occurred due to declines in fair value or other market conditions. When the amortized cost basis of an available-for-sale debt security exceeds its fair value, the security is deemed to be impaired. The portion of an impairment related to credit losses is determined by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security and is recorded as a charge in the Consolidated Statements of Operations. The remainder of an impairment 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.

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, trading securities, available-for-sale securities, foreign currency forward contracts and contingent consideration payables associated with acquisitions. All other financial instruments are short-term in nature and the carrying amounts reported on the Consolidated Statements of Financial Condition approximate fair value.

Receivables from and Payables to Broker-dealers, Clearing Organizations and Customers

Receivables from broker-dealers, clearing organizations and customers include amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (“securities failed-to-deliver”) and cash deposits held at clearing organizations and clearing brokers to facilitate the settlement and clearance of matched principal transactions. Payables to broker-dealers, clearing organizations and customers include amounts payable for securities not received by the Company from a seller by the settlement date (“securities failed-to-receive”). Securities failed-to-deliver and securities failed-to-receive for transactions executed on a matched principal basis where the Company serves as a counterparty to both the buyer and the seller are recorded on a settlement date basis. The Company presents its securities failed-to-deliver and securities failed-to-receive balances on a net-by-counterparty basis within receivables from and payables to broker-dealers, clearing organizations and customers. The difference between the Company’s trade-date receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade date basis.

Allowance for Credit Losses

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 credit losses is based on an estimate of the amount of potential credit losses in existing accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific collection issues that have been identified. Account balances are grouped for evaluation based on various risk characteristics, including billing type, legal entity, and geographic region. Additions to the allowance for credit losses are charged to bad debt expense, which is included in general and administrative expense in the Company’s Consolidated Statements of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses.

The allowance for credit losses was $0.4 million and $0.6 million as of June 30, 2023 and December 31, 2022, respectively. The provision for bad debts, write-offs and other charges against the allowance for credit losses were immaterial for the three and six months ended June 30, 2023 and 2022.

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. The Company amortizes leasehold improvements on a straight-line basis 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, including, among other items, employee compensation and related benefits and third-party consulting costs at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. 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.

Cloud Computing Costs

The Company capitalizes certain costs associated with cloud computing arrangements, including, among other items, vendor software development costs billed to us that are part of the application development stage. These costs are recorded as a prepaid asset on the Consolidated Statements of Financial Condition and are amortized over the period of the hosting service contract, which ranges from one to five years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Foreign Currency 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 other, net in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to economically hedge its foreign currency transaction gains and losses. Realized and unrealized gains and losses on these forward contracts are included in other, net in the Consolidated Statements of Operations. The Company records the fair value of the forward contract asset in prepaid expenses and other assets or the fair value of the forward contract liability in accounts payable, accrued expenses and other liabilities in the Consolidated Statements of Financial Condition.

Revenue Recognition

The Company’s classification of revenues in the Consolidated Statements of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has four revenue streams as described below.

Commission Revenue – The Company charges its broker-dealer clients variable transaction fees for trades executed on its platforms and, under certain plans, distribution fees or monthly minimum fees to use the platforms for a particular product area. Variable transaction fees are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on the platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. Bonds that are more actively traded or that have shorter maturities generally generate lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. Under the Company’s disclosed trading transaction fee plans, variable transaction fees, distribution fees and unused monthly fee commitments are invoiced and recorded on a monthly basis.

For Open Trading trades that the Company executes between and among institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller, the Company earns its commission through the difference in price between the two trades. The commission is collected upon settlement of the trade, which typically occurs within one to two trading days after the trade date. For the majority of the Company’s U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis. The following table presents commission revenue by fee type:

Information services – Information services includes data licensed to the Company’s broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. The nature and timing of each performance obligation may vary as these contracts are either subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services that are transferred at a point in time. Revenues for services transferred over time are recognized ratably over the contract period as the Company’s performance obligation is met, whereas revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period. The following table presents information services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022

Total information services revenues	$	11,655	$	9,396	$	22,665	$	19,205

Post-trade services – Post-trade services revenue is generated from regulatory transaction reporting, trade publication and trade matching services. Customers are generally billed monthly in arrears and revenue is recognized in the period transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. The Company also generates one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is completed. The following table presents post-trade services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,

Other revenues – Other revenues primarily includes revenue from telecommunications line charges to broker-dealer clients.

Contract liabilities consist of deferred revenues that the Company records when cash payments are received or due in advance of services to be performed. The revenue recognized from contract liabilities and the remaining balance is shown below:

	December 31, 2022		Payments received in advance of services to be performed		Revenue recognized for services performed during the period			Foreign Currency Translation		June 30, 2023

Total deferred revenue	$	3,990	$	18,250	$	(17,975	)	$	39	$	4,304

The majority of the Company’s information services and post-trade services contracts are short-term in nature with durations of less than one year. For contracts with original durations extending beyond one year, the aggregate amount of the transaction price allocated to remaining performance obligations was $59.3 million as of June 30, 2023. The Company expects to recognize revenue associated with the remaining performance obligations over the next 49 months.

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. Forfeitures are recognized as they occur.

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. Tax benefits for uncertain tax positions are recognized when it is more likely than not that the positions will be sustained upon examination based on their technical merits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statements of Operations. All tax effects related to share-based payments are recorded in the provision for income taxes in the periods during which the awards are exercised or vest.

Business Combinations, Goodwill and Intangible Assets

Business combinations 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 requires judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates, customer attrition rates and asset lives.

The Company operates as a single reporting unit. Following an acquisition, goodwill no longer retains its identification with a particular acquisition, but instead becomes identifiable with the entire reporting unit. As a result, all of the fair value of the Company is available to support the value of goodwill. An impairment review of goodwill is performed on an annual basis, at year-end, or more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives which range from one to 15 years using either a straight-line or accelerated amortization method based on the pattern of economic benefit the Company expects to realize from such assets. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Equity Investments and Consolidation

The Company evaluates equity investments for potential consolidation under the voting-interest or variable-interest models. The Company consolidates investees over which the Company determines it has control under the voting interest model, generally greater than 50% ownership, or for which the Company is the primary beneficiary under the variable-interest model. The Company uses the equity method of accounting when it exercises significant influence over the investee, but does not have operating control, generally between 20% and 50% ownership. Under the equity method of accounting, original investments are recorded at cost in prepaid expenses and other assets on the Consolidated Statements of Financial Condition and adjusted by the Company’s proportionate share of the investees’ undistributed earnings or losses. Equity investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

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 GAAP 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.

3. Regulatory Capital Requirements

One of the Company’s U.S. subsidiaries is registered as a broker-dealer and therefore is subject to the applicable rules and regulations of the SEC and the Financial Industry Regulatory Authority (“FINRA”). These rules contain minimum net capital requirements, as defined in the applicable regulations. Certain of the Company’s foreign subsidiaries are regulated by the Financial Conduct Authority (“FCA”) in the U.K. or other foreign regulators and must maintain financial resources, as defined in the applicable regulations, in excess of the applicable financial resources requirement. As of June 30, 2023, each of the Company’s subsidiaries that are subject to these regulations had net capital or financial resources in excess of their minimum requirements. As of June 30, 2023, the Company’s subsidiaries maintained aggregate net capital and financial resources that were $550.0 million in excess of the required levels of $29.0 million.

The Company’s U.S. broker-dealer subsidiary is required to segregate funds in a special reserve bank account for the benefit of customers pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As of June 30, 2023, the U.S. broker-dealer subsidiary had a balance of $52.0 million in its special reserve bank account. This U.S. broker-dealer subsidiary also maintained net capital that was $330.2 million in excess of the required level of $3.7 million.

Each of the Company’s U.S. and foreign regulated subsidiaries are subject to local regulations which generally limit, or require the prior notification to or approval from such regulated entity’s principal regulator before, the repayment of borrowings from the Company or affiliates, paying cash dividends, making loans to the Company or affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources.

8. Income Taxes

The Company's provision for income taxes includes U.S. federal, state and local, and foreign taxes. The Company’s effective tax rate was 24.2% and 25.3% for the three months ended June 30, 2023 and 2022, respectively, and 24.6% and 26.8% for the six months ended June 30, 2023 and 2022, respectively. During the six months ended June 30, 2022, the Company's provision for income taxes included $3.2 million of expense related to a settlement with New York State to resolve the 2010 to 2014 audits. The Company’s effective tax rate can vary from period to period depending on geographic mix of our earnings, changes in tax legislation and tax rates and the amount and timing of excess tax benefits related to share-based payments, among other factors.

The Company or one of its subsidiaries files U.S. federal, state and foreign income tax returns. The Company is currently under a New York State income tax examination for tax years 2015 through 2017 and a New York City income tax examination for the tax years 2016 through 2018. At this time, the Company cannot estimate when the examinations will conclude or the impact such examinations will have on the Company’s Consolidated Financial Statements, if any. Generally, other than the New York City and New York State audits, the Company is no longer subject to tax examinations by tax authorities for years prior to 2019.

9. Stock-Based Compensation Plans

Equity Incentive Plan

The Company maintains the MarketAxess Holdings Inc. 2020 Equity Incentive Plan (the “2020 Plan”), which provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, or other stock-based awards as incentives to encourage employees, consultants and non-employee directors to participate in the long-term success of the Company. As of June 30, 2023, there were 2,429,781 shares available for grant under the 2020 Plan.

Total stock-based compensation expense was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Employees	$	6,647	$	6,059	$	13,747	$	13,701
Non-employee directors		243		444		631		901
Total stock-based compensation	$	6,890	$	6,503	$	14,378	$	14,602

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

During the six months ended June 30, 2023, the Company granted a total of (i) 72,777 restricted stock units, (ii) 13,908 options to purchase shares of common stock and (iii) performance stock units with an expected pay-out at target of 23,302 shares of common stock. The fair values of the restricted stock units and performance stock units were based on a weighted-average fair value per unit at the grant date of $353.63 and $386.14, respectively. Based on the Black-Scholes option pricing model, the weighted-average fair value for each option granted was $123.47 per share.

Included in the above totals are shares granted in April 2023 to the Company’s Chief Executive Officer in connection with his appointment to the position, consisting of: (i) 2,729 restricted stock units with a grant date fair value of $1.05 million, as determined by the Company’s Compensation and Talent Committee by dividing the award value by the average closing price of the Company’s common stock on the ten trading days leading up to and including the grant date, rounded to the nearest whole number; and (ii) 5,039 target performance stock units with a grant date fair value of $2.45 million, as determined by the Company’s Compensation and Talent Committee using the Monte Carlo method. The restricted stock units vest 25% on each of the third and fourth anniversary of the grant date and 50% on the fifth anniversary of the grant date, subject to continued service through the respective vesting dates. The performance stock units vest 25% on each of the third and fourth anniversaries of the grant date and 50% on the fifth anniversary of the grant date, subject to certification of the performance criteria and continued service through the respective vesting dates.

As of June 30, 2023, the total unrecognized compensation cost related to all non-vested awards was $55.0 million. That cost is expected to be recognized over a weighted-average period of 1.6 years.

Employee Stock Purchase Plan

The Company maintains the MarketAxess Holdings Inc. 2022 Employee Stock Purchase Plan (the “ESPP”). The ESPP has a series of six-month offering periods, with a new offering period beginning on the first trading day on or after February 16 and August 16 of each year. Subject to certain limitations, employees may contribute up to $2,000 of such employee’s total eligible compensation per month towards the purchase of common stock via payroll deductions. Shares are purchased at a 15% discount off the lesser of: (i) the fair market value per share on the first day of each offering period; and (ii) the fair market value per share on the purchase date, but in no event less than par value. The Company issued 1,928 shares of common stock on February 15, 2023 under the ESPP. As of June 30, 2023, there were 119,293 shares available for purchase under the ESPP.

10. Earnings Per Share

The following table sets forth basic and diluted weighted average shares outstanding used to compute earnings per share:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands, except per share amounts)
Basic weighted average shares outstanding		37,485		37,529		37,482		37,456
Dilutive effect of stock options and restricted stock		103		79		135		260
Diluted weighted average shares outstanding		37,588		37,608		37,617		37,716
Basic earnings per share	$	1.60	$	1.78	$	3.56	$	3.52
Diluted earnings per share		1.59		1.78		3.55		3.49

Stock options and restricted stock totaling 240,079 shares and 333,413 shares for the three months ended June 30, 2023 and 2022, respectively, and 209,614 shares and 254,028 shares for the six months ended June 30, 2023 and 2022, 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.

11. Credit Agreements and Short-term Financing

Credit Agreement

On October 15, 2021, the Company entered into a three-year revolving credit facility (the “Credit Agreement”) provided by a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent, which provides aggregate commitments totaling $500.0 million, consisting of a revolving credit facility and a $5.0 million letter of credit sub-limit for standby letters of credit and a $50.0 million sub-limit for swingline loans. The Credit Agreement will mature on October 15, 2024, with the Company's option to request up to two additional 364-day extensions at the discretion of each lender and subject to customary conditions. Subject to satisfaction of certain specified conditions, the Company is permitted to upsize the Credit Agreement by up to $250.0 million in total.

Borrowings under the Credit Agreement bore interest at a rate per annum equal to the base rate or adjusted LIBOR plus an applicable margin that varies with the Company’s consolidated total leverage ratio. On March 28, 2023, the Company entered into a first amendment to the Credit Agreement, which among other things, established customary Secured Overnight Financing Rate (“SOFR”) provisions in lieu of the London Interbank Offered Rate (“LIBOR”) provisions set forth in the Credit Agreement. Following such amendment, borrowings under the Credit Agreement will bear interest at a rate per annum equal to the alternate base rate or the adjusted term SOFR rate, plus an applicable margin that varies with the Company’s consolidated total leverage ratio.

The Credit Agreement requires that the Company satisfy certain covenants, including a requirement to not exceed a maximum consolidated total leverage ratio. As of June 30, 2023, the Company had $0.1 million in letters of credit outstanding and $499.9 million in available borrowing capacity under the Credit Agreement. The Company incurred interest expense under the Credit Agreement of $0.1 million and $0.2 million for the three months ended June 30, 2023 and 2022, respectively, and $0.1 million and $0.3 million for the six months ended June 30, 2023 and 2022, respectively.

Uncommitted Collateralized Agreements

In connection with their self-clearing operations, certain of the Company’s U.S. and U.K. operating subsidiaries maintain agreements with their settlement bank to allow the subsidiaries to borrow in the aggregate of up to $500.0 million on an uncommitted basis, collateralized by eligible securities pledged by the subsidiaries to the settlement bank, subject to certain haircuts. Borrowings under these agreements will bear interest at a base rate per annum equal to the higher of the upper range of the Federal Funds Rate, 0.25% or one-month SOFR, plus 1.00%.

The Company incurred no interest expense on borrowings under such agreements during the three months ended June 30, 2023 and $0.1 million of interest expense during six months ended June 30, 2023. The Company incurred no interest expense on borrowings under such agreements during the three and six months ended June 30, 2022. As of June 30, 2023, the Company had no borrowings outstanding and up to $500.0 million in available uncommitted borrowing capacity under such agreements.

Short-term Financing

Under arrangements with their settlement banks, certain of the Company’s U.S. and U.K. operating subsidiaries may receive overnight financing in the form of bank overdrafts. The Company incurred interest expense on such overnight financing of $0.1 million during each of the three months ended June 30, 2023 and 2022, and $0.1 million and $0.2 million of interest expense during the six months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, the Company had no overdrafts payable outstanding.

12. Leases

The Company has operating leases for corporate offices with initial lease terms ranging from one year to 15 years. Certain leases contain options to extend the initial term at the Company’s discretion. The Company accounts for the option to extend when it is reasonably certain of being exercised. The Company’s lease agreements do not contain any material residual value guarantees, restrictions or covenants.

The following table presents the components of lease expense for the three and six months ended June 30, 2023 and 2022:

		Three Months Ended June 30,					Six Months Ended June 30,
Lease cost:	Classification	2023		2022			2023		2022
		(In thousands)
Operating lease cost	Occupancy	$	2,882	$	3,345		$	5,993	$	6,655
Operating lease cost for subleased/assigned properties	Other, net		—		13			—		469
Variable lease costs	Occupancy		347		4			398		11
Sublease income subleased/assigned properties	Other, net		—		(15	)		—		(405	)
Net lease cost		$	3,229	$	3,347		$	6,391	$	6,730

The Company determines whether an arrangement is, or includes, a lease at contract inception. Operating lease right-of-use assets and liabilities are recognized at commencement date and are initially measured based on the present value of lease payments over the defined lease term. As the Company's leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at the adoption date in determining the present value of lease payments.

The weighted average remaining lease term and weighted average discount rate are as follows:

	As of
Lease Term and Discount Rate	June 30, 2023			December 31, 2022
Weighted average remaining lease term (in years)		10.2			10.6
Weighted average discount rate		5.9	%		5.9	%

The following table presents the maturity of lease liabilities as of June 30, 2023:

	(In thousands)
Remainder of 2023	$	5,551

13. Commitments and Contingencies

Legal

In the normal course of business, the Company and its subsidiaries included in the consolidated financial statements may be involved in various lawsuits, proceedings and regulatory examinations. The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings, if any, utilizing the latest information available. For matters where it is probable that the Company will incur a material loss and the amount can be reasonably estimated, the Company will establish an accrual for the loss. Once established, the accrual will be adjusted to reflect any relevant developments. When a loss contingency is not both probable and estimable, the Company does not establish an accrual.

Based on currently available information, the outcome of the Company’s outstanding matters is not expected to have a material adverse impact on the Company’s financial position. It is not presently possible to determine the ultimate exposure to these matters and there is no assurance that the resolution of the outstanding matters will not significantly exceed any reserves accrued by the Company.

Other

The Company, through certain of its subsidiaries, executes securities transactions between its institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller in trades. The Company’s operating subsidiaries settle such transactions pursuant to their self-clearing operations or through the use of third-party clearing brokers or settlement agents. Settlement typically occurs within one to two trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded. Under both the self-clearing and the third-party clearing models, the Company may be exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction or if there is an error in executing a matched principal transaction. Pursuant to the terms of the securities clearing agreements, each third-party clearing broker has the right to charge the Company for any losses they suffer resulting from a counterparty’s failure on any of the Company’s trades. The Company did not record any liabilities or losses with regard to counterparty failures for the six months ended June 30, 2023 and 2022.

In the normal course of business, the Company enters into contracts that contain a variety of representations, warranties and indemnification provisions. 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 material loss to be remote.

14. Share Repurchase Programs

In January 2021, the Board of Directors authorized a share repurchase program for up to $100.0 million that commenced in April 2021 and was exhausted in January 2022. In January 2022, the Board of Directors authorized a new share repurchase program for up to $150.0 million. There were no shares repurchased in connection with the Company’s share repurchase program during the three and six months ended June 30, 2023. Shares repurchased under each program will be held in treasury for future use.

15. Segment and Geographic Information

The Company operates electronic platforms for the trading of fixed-income securities and provides related data, analytics, compliance tools and post-trade services. The Company considers its operations to constitute a single business segment because of the highly integrated nature of these products and services, the financial markets in which the Company competes and the Company’s worldwide business activities. The Company believes that results by geographic region or client sector are not necessarily meaningful in understanding its business.

For the six months ended June 30, 2023 and 2022, the U.K. was the only individual foreign country in which the Company had a subsidiary that accounted for 10% or more of the total revenues or total long-lived assets. Revenues and long-lived assets are attributed to a geographic area based on the location of the particular subsidiary. Long-lived assets are defined as furniture, equipment, leasehold improvements and capitalized software. Revenues for the three and six months ended June 30, 2023 and 2022 and long-lived assets as of June 30, 2023 and December 31, 2022 were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,

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 undertake no obligation to revise or update any forward-looking statements contained in this report, except to the extent required by applicable law. Our Company’s 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, perhaps 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,” and in our Form 10-K for the year ended December 31, 2022, including in Part I, Item 1A, “Risk Factors” and Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Executive Overview

MarketAxess operates leading electronic trading platforms delivering greater trading efficiency, a diversified pool of liquidity and significant cost savings to our clients across the global fixed-income markets. Over 2,000 institutional investor and broker-dealer firms use our patented trading technology to efficiently trade U.S. high-grade bonds, U.S. high-yield bonds, emerging market debt, Eurobonds, municipal bonds, U.S. government bonds and other fixed-income securities. Our award-winning Open Trading marketplace is widely regarded as the preferred all-to-all trading solution in the global credit markets, creating a unique liquidity pool for a broad range of credit market participants. Drawing on a diverse set of trading protocols, including request-for-quote, live order books, sessions-based trading and portfolio trading solutions, as well as our deep data and analytical resources, we believe that we connect the most robust network of participants through a full trading lifecycle solution that also includes automated trading solutions, intelligent data and index products and a range of post-trade services.

We operate in a large and rapidly growing market that provides us with a significant opportunity for future growth. Many of our largest current product areas, and areas of future growth, have relatively low levels of trading electronification, which further increases the size of our addressable market. Our platforms’ innovative technology solutions are designed to capitalize on this addressable market by increasing the number of potential trading counterparties and providing our clients with a menu of solutions to address the full lifecycle of fixed-income trading. We offer Open Trading and automated trading solutions for most of our products. We believe that Open Trading drives meaningful price improvement for our clients and reduces risk in fixed-income markets by creating a global, diversified pool of liquidity whereby our institutional investor clients, dealer clients and alternative liquidity providers can all interact on an anonymous basis. Institutional investors can also send trading inquiries directly to their traditional broker-dealer counterparties through a disclosed RFQ, while simultaneously accessing additional counterparties through our anonymous Open Trading solutions.

We also provide a number of integrated and actionable data offerings, including Composite+ and Axess All, to assist clients with real-time pricing and trading decisions and transaction cost analysis. We have a range of post-trade services, including straight-through processing, trade matching, trade publication, regulatory transaction reporting and market and reference data across fixed-income and other products.

We derive revenue from commissions for trades executed on our platforms, information services, post-trade services and other revenues. Our expenses consist of employee compensation and benefits, depreciation and amortization, technology and communication expenses, professional and consulting fees, occupancy, marketing and advertising, clearing costs and general and administrative expenses.

Our objective is to provide the leading global electronic trading platforms for fixed-income securities, connecting broker-dealers and institutional investors more easily and efficiently, while offering a broad array of trading information and technology services to market participants across the trading cycle. The key elements of our strategy are discussed in Part I, Item 1. “Business – Our Strategy” of our Form 10-K for the year ended December 31, 2022.

25

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 impact trading volume. These factors could have a material adverse or positive 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, the duration of bonds traded, economic and political conditions in the United States, Europe and elsewhere, and the consolidation or contraction of our broker-dealer and institutional investor clients.

The fixed-income markets experienced challenging operating conditions during the second quarter of 2023 stemming from the regional banking crisis in April and uncertainty around the status of the U.S. debt ceiling negotiations leading into June. The difficult market conditions tempered growth in U.S. credit market volumes, which only increased 42 basis points to $2.3 trillion, up from $2.2 trillion in the second quarter of 2022. We believe the low market volume growth and reduced market volatility in the quarter had a negative impact on our ability to increase U.S. credit volumes traded on our platforms. The continued rise in corporate bond yields and lower years to maturity of bonds traded on our platforms relative to the second quarter of 2022 contributed to a decrease in the duration of U.S. high-grade bonds traded on our platforms, which had a negative effect on our average variable transaction fee per million, principally in U.S. high-grade, relative to the prior year.

The closures of Silicon Valley Bank and Signature Bank in March 2023 created bank-specific and broader financial institution liquidity risk and concerns, which persisted throughout much of the second quarter. Future adverse developments with respect to specific financial institutions or the broader financial services industry may lead to market-wide liquidity shortages, impair the ability of companies to access working capital needs, and create additional market and economic uncertainty.

There has been increased demand for green bonds and other securities linked to environmental, social and governance factors in the fixed-income markets in which we operate. Based on the interest we are receiving from investors, we expect such increased demand to continue.

Because the majority of our assets are short-term in nature, they are not significantly affected by inflation. However, the rate of inflation has, and may continue to affect our expenses, such as employee compensation, technology and communications expenses, which may not be readily recoverable in the prices of our services. To the extent inflation continues to result in rising interest rates or has other adverse effects on the securities markets or the economy, it may adversely affect our financial position and results of operations.

We expect that current cash and investment balances, in combination with cash flows that are generated from operations and the ability to borrow under our Credit Agreement, will be sufficient to meet our liquidity needs and planned capital expenditure requirements for at least the next twelve months. We ended the quarter with a strong balance sheet, no borrowings under our Credit Agreement and with capital significantly in excess of our regulatory requirements.

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 or all-to-all trading platforms. Competitors, including companies in which some of our broker-dealer clients have invested, have developed or acquired electronic trading platforms or have announced their intention to explore the development of electronic platforms or information networks that may compete with us.

We primarily compete on the basis of our client network, the liquidity provided by our dealer, and, to a growing extent, institutional investor clients, the total transaction costs associated with our services, the breadth of products, protocols and services offered, as well as the quality, reliability, security and ease of use of our platforms. 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 enhanced by the unique liquidity provided by our Open Trading functionalities and the familiarity and integration of our broker-dealer and institutional investor clients with our electronic trading platforms and other systems. We have focused on the unique aspects of the credit markets we serve in the development of our platforms, working closely with our clients to provide a system that is suited to their needs.

26

Regulatory Environment

Our business is subject to extensive regulations in the United States and internationally, which may expose us to significant regulatory risk and cause additional legal costs to ensure compliance. The existing legal framework that governs the financial markets is periodically reviewed and amended, resulting in the enactment and enforcement of new laws and regulations that apply to our business. The SEC recently proposed rules that will expand Regulation ATS and Regulation SCI to alternative trading systems (ATS) that trade government securities and amend the SEC rule regarding the definition of an “exchange” to include Communication Protocol Systems, such as our RFQ protocols. Based on these proposed rules, we expect that we will have to operate all of our trading protocols in compliance with Regulation ATS and we could become subject to Regulation SCI for certain parts of our business in the future. The SEC has also adopted final rule amendments that, effective May 2024, will shorten the standard settlement cycle for most broker-dealer securities transactions from two business days after the trade date (T+2) to one business day after the trade date (T+1). The shortening of the settlement cycle will lead to a reduction in the length of exposure to trading counterparties and lower margin requirements for our clearing operations, but it is also expected to increase the operational costs and complexities associated with cross border transactions conducted on our platforms. The impact of any of these reform efforts on us and our operations remains uncertain.

As a result of Brexit, we obtained authorizations from the AFM for our subsidiaries in the Netherlands in 2019. We now provide regulated services to our clients within the E.U. in reliance on the cross-border services passport held by our Dutch subsidiaries. Brexit has led to an ongoing divergence between the U.K. and E.U. financial regulations, which has made it more difficult and costly to comply with the extensive government regulation to which we are subject. The cost and complexity of operating across increasingly divergent regulatory regimes has increased and is likely to continue to increase in the future.

Compliance with regulations may require us to dedicate additional financial and operational resources, which may adversely affect our profitability. However, we believe new regulations may also increase demand for our platforms and we believe we are well positioned to benefit from those regulatory changes that cause market participants to seek electronic trading platforms that meet the various regulatory requirements and help them comply with their regulatory obligations.

For further description of the regulations which govern our business, see Part1, Item I. “Business – Government Regulation” of our Form 10-K for the year ended December 31, 2022.

Technology Environment

We must continue to enhance and improve our electronic trading platforms. 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 existing and prospective broker-dealer and institutional investor clients and respond to technological advances and emerging industry and regulatory standards and practices on a cost-effective and timely basis. We plan to continue to focus on technology infrastructure initiatives and improving our platforms with the goal of further enhancing our leading market position.

As the overall share of electronic trading grows in global credit products, we are experiencing continued demand for, and growth in, our automated trading solutions. For example, in the second quarter of 2023, we launched a pilot of Adaptive Auto-X, a fixed-income client algorithm, which allows clients to build customized trading algorithms and enhanced workflows to handle larger sized trades. We also support a large and growing base of dealer market making algorithms. In the second quarter of 2023, there were 7.4 million dealer algorithmic responses on our platforms, up 30.7% from the second quarter of 2022. Trading volumes in our automated trading protocols rose to $73.1 billion in the second quarter of 2023, up 26.8% from $57.6 billion in the second quarter of 2022.

We experience, and are not immune from, cyber-attacks and attempted data security breaches from time to time. However, MarketAxess has not experienced any material information security breaches in at least the past three years. Cybersecurity incidents could impact revenue and operating income and increase costs. We therefore continue to make investments in our cybersecurity infrastructure and training of employees, which may result in increased costs, to strengthen our cybersecurity measures.

Trends in Our Business

The majority of our revenue is derived from commissions for transactions executed on our platforms between and among our institutional investor and broker-dealer clients and monthly distribution fees. We believe that the following are the key variables that impact the notional value of such transactions on our platforms and the amount of commissions and distribution fees earned by us:

• the number of participants on our platforms and their willingness to use our platforms instead of competitors' platforms or other execution methods;

• the frequency and competitiveness of the price responses by participants on our platforms;

• the number of markets that are available for our clients to trade on our platforms;

• the overall level of activity in these markets;

• the duration of the bonds trading on our platforms; and

• the particular fee plan under which we earn commissions and distribution fees.

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 platforms, 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.

As further described under “— Critical Factors Affecting our Industry and our Company — Economic, Political and Market Factors” and “— Results of Operations — Six Months Ended June 30, 2023 Compared to Six Months Ended June 30, 2022,” our trading volumes and average variable transaction fee per million decreased compared to the six months ended June 30, 2022.

Components of Our Results of Operations

Commission Revenue

Commissions are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on our platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. 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 Open Trading trades that we execute between and among institutional investor and broker-dealer clients on a matched 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 trades. For the majority of U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis.

Credit Commissions. Credit includes U.S. high-grade corporate bonds, high-yield bonds, emerging markets bonds, Eurobonds, municipal bonds and leveraged loans. Our U.S. high-grade corporate bond fee plans generally incorporate variable transaction fees and fixed distribution fees billed to our broker-dealer clients on a monthly basis. Certain broker-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 these fee plans, we electronically add the transaction fee to the spread quoted by the broker-dealer client. The U.S. high-grade transaction fee is generally designated in basis points in yield and, as a result, is subject to fluctuation depending on the duration of the bond traded.

Commissions for high-yield bonds, emerging markets bonds, Eurobonds, municipal bonds and leveraged loans generally vary based on the type of the instrument traded using standard fee schedules. Our high-yield fee plan structure is similar to our U.S. high-grade fee plans. Certain dealers participate in a high-yield fee plan that incorporates a variable transaction fee and a fixed distribution fee, while other dealers participate in a plan that does not contain monthly distribution fees and instead incorporates additional per transaction execution fees and minimum monthly fee commitments.

The average credit fees per million may vary in the future due to changes in yield, years-to-maturity and nominal size of high-grade bonds traded on our platforms and changes in product mix or trading protocols.

Credit distribution fees include any unused monthly fee commitments under our variable fee plans.

Rates Commissions. Rates includes U.S. Treasury, U.S. agency and European government bonds. Commissions for rates products generally vary based on the type of the instrument traded. U.S. Treasury fee plans are typically volume tiered and can vary based on the trading protocol. The average rates fee per million may vary in the future due to changes in product mix or trading protocols.

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

28

Information Services

We generate revenue from data licensed to our broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. These revenues are either for subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services. Revenues for services transferred over time are recognized ratably over the contract period while revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period.

Post-trade Services

We generate revenue from regulatory transaction reporting, trade publication and trade matching services. Customers are generally billed in the current month or monthly in arrears and revenue is recognized in the period that the transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. We also generate one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is complete.

Other Revenue

Other revenue includes revenue generated from telecommunications line charges to broker-dealer clients.

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.

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, which range from one to 15 years, using either a straight-line or accelerated amortization method based on the pattern of economic benefit that we expect to realize from such assets. 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 software and licenses, maintenance on software and hardware, cloud hosting costs, data feeds provided by outside vendors, U.S. government bonds technology platform licensing fees, data center hosting costs and our internal network connections. 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 other consultants for services provided for the maintenance of our trading platforms, information and post-trade services products and other services.

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 branding 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 platforms, information services and post-trade services.

Clearing Costs. Clearing costs consist of fees that we are charged by third-party clearing brokers and depositories for the clearing and settlement of matched principal trades, regulatory reporting fees and variable transaction fees assessed by the provider of our third-party middle office system.

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

Expenses may continue to grow in the future, notably in employee compensation and benefits as we increase headcount to support investment in new products, operational support and geographic expansion, depreciation and amortization due to increased investment in new products and enhancements to our trading platforms, and technology and communication costs. Expenses may also grow due to increased regulatory complexity, acquisitions or the continued effects of inflation.

29

Other Income (Expense)

Interest Income. Interest income consists of interest income earned on our cash and cash equivalents, restricted cash, deposits and investments.

Interest Expense. Interest expense consists of financing charges incurred on short-term borrowings.

Equity in Earnings of Unconsolidated Affiliate. Equity in earnings of unconsolidated affiliate represents the proportionate share of our equity method investee's net income.

Other, Net. Other, net consists of realized and unrealized gains and losses on trading security investments and foreign currency forward contracts, foreign currency transaction gains or losses, investment advisory fees, credit facility administrative fees, gains or losses on revaluations of contingent consideration payable and other miscellaneous revenues and expenses.

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 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. Critical accounting estimates for us include stock-based compensation and contingent consideration payable.

Stock-based compensation

We maintain the 2020 Plan, which provides for the grant of stock options, stock appreciation rights, restricted stock, performance shares, performance units, restricted stock units, performance stock units, or other stock-based awards as incentives to encourage employees, consultants and non-employee directors to participate in our long-term success. We make critical accounting estimates related to performance shares and performance stock units granted under the 2020 Plan.

In 2021, 2022 and 2023, annual performance-based equity awards (the “Performance Equity Awards”) were granted to the executive officers and certain senior managers. Each Performance Equity Award is earned or forfeited based on our level of achievement of certain predetermined metrics, including pre-tax adjusted operating margin and market share for the 2021 awards, and pre-tax adjusted operating margin, U.S. credit market share, and revenue growth excluding U.S. credit for the 2022 and 2023 awards. The vested share pay-out ranges from zero to 200% of the Performance Equity Award target. The number of Performance Equity Awards that vest, if any, will be determined by the level of achievement of the performance metrics during the three-year performance periods, as certified by the Compensation and Talent Committee following the conclusion of the performance period. In addition, participants must provide continued service through the vesting date, subject to death, disability and qualified retirement exceptions. Compensation expense for the Performance Equity Awards is measured using the fair value of our stock at the grant date and estimates of future performance and actual share payouts. Each period, we make estimates of the current expected share payouts and adjust the life-to-date compensation expense recognized since the grant date. As of June 30, 2023, a 10% change in the expected final share payouts would increase or decrease the life-to-date compensation expense by $1.5 million. The estimated final share payouts for the 2021 and 2022 awards as of June 30, 2023 decreased 15.6% compared to December 31, 2022.

Recent Accounting Pronouncements

See Note 2 to the Consolidated Financial Statements for a discussion of recent accounting pronouncements.

Segment Results

We operate electronic platforms for the trading of fixed-income securities and provide related data, analytics, compliance tools and post-trade services. We consider our operations to constitute a single business segment because of the highly integrated nature of these products and services, the financial markets in which we compete and our worldwide business activities. We believe that results by geographic region or client sector are not necessarily meaningful in understanding our business. See Note 15 to the Consolidated Financial Statements for certain geographic information about our business required by GAAP.

For volume reporting purposes, transactions in foreign currencies are converted to U.S. dollars at average monthly rates.

The 1.8% decrease in our U.S. high-grade volume was principally due to a decrease in our estimated market share, partially offset by an increase in estimated market volumes. Estimated U.S. high-grade market volume as reported by FINRA’s Trade Reporting and Compliance Engine (“TRACE”) increased by 5.8% to $1.7 trillion for the three months ended June 30, 2023 compared to the three months ended June 30, 2022. Our estimated market share of total U.S. high-grade corporate bond volume decreased to 20.7% for the three months ended June 30, 2023 from 22.3% for the three months ended June 30, 2022. High-yield and emerging markets volumes decreased by 16.8% and 4.0% respectively, mainly due to decreases in estimated market volumes. Eurobond volumes increased by 30.2%, mainly due to increases in estimated market volumes and our estimated market share. Rates trading volume decreased 32.5%, primarily due to a decrease in our estimated market share.

Our average variable transaction fee per million for the three months ended June 30, 2023 and 2022 was as follows:

Credit average variable transaction fee per million decreased by 5.0% to $157.42 per million for the three months ended June 30, 2023 mainly due to a decrease in the duration of U.S. high-grade bonds traded on our platforms.

Information Services. Information services revenue increased by $2.3 million for the three months ended June 30, 2023 mainly due to net new data contract revenue.

Post-Trade Services. Post-trade services revenue increased by $0.3 million for the three months ended June 30, 2023 principally due to net new contract revenue.

Open Trading credit volume totaled $504.9 billion during the six months ended June 30, 2023, up 9.2%, and Open Trading credit variable transaction fees represented 35.1% and 31.6% of total variable transaction fees for the six months ended June 30, 2023 and 2022, respectively.

Credit fixed distribution fees increased $7.2 million mainly due to new dealers on fixed distribution fee plans and certain dealers moving to plans with higher fixed distribution fees.

For volume reporting purposes, transactions in foreign currencies are converted to U.S. dollars at average monthly rates.

The 6.3% increase in our U.S. high-grade volume was principally due to an increase in overall market volume, offset by lower estimated market share. Estimated U.S. high-grade market volume as reported by TRACE increased by 12.9% to $3.7 trillion for the six months ended June 30, 2023. Our estimated market share of total U.S. high-grade corporate bond volume decreased to 20.3% for the six months ended June 30, 2023 from 21.5% for the six months ended June 30, 2022. High-yield and Eurobond volumes increased by 1.7% and 28.0%, respectively, mainly due to increases in our estimated market share. Emerging markets volumes decreased by 1.4%, mainly due to a decrease in estimated market volumes partially offset by an increase in our estimated market share. Other credit volumes increased 22.3%, driven by higher municipal bonds volume on higher estimated market share. Rates trading volume decreased 17.5%, primarily due to a decrease in our estimated market share.

Credit average variable transaction fee per million decreased by 4.5% to $161.43 per million for the six months ended June 30, 2023 mainly due to a decrease in the duration of U.S. high-grade bonds traded on our platforms.

Information Services. Information services revenue increased by $3.5 million for the six months ended June 30, 2023 mainly due to net new data contract revenue of $4.1 million partially offset by the negative impact of foreign currency fluctuations of $0.6 million.

Post-Trade Services. Post-trade services revenue increased by $0.3 million for the six months ended June 30, 2023 principally due to net new contract revenue of $1.1 million, partially offset by the negative impact of foreign currency fluctuations of $0.8 million.

Expenses

The following table summarizes our expenses for the six months ended June 30, 2023 and 2022:

	Six Months Ended June 30,
	2023		2022		$ Change			% Change

Total expenses	$	211,932	$	195,394	$	16,538			8.5		%

Employee compensation and benefits increased by $7.5 million, primarily due to increases in salaries, taxes and benefits on higher employee headcount of $8.6 million, offset by lower employee incentive compensation of $1.2 million.

Depreciation and amortization increased by $3.1 million, primarily due to higher amortization of software development costs of $2.6 million, higher amortization of production hardware and software of $1.3 million and higher amortization of intangibles of $0.4 million, offset by lower amortization of software licenses of $1.2 million. For the six months ended June 30, 2023 and 2022, $1.3 million and $2.7 million, respectively, of equipment purchases and leasehold improvements and $21.7 million and $18.6 million, respectively, of software development costs were capitalized.

Technology and communications expenses increased by $5.6 million, primarily due to higher software subscription costs of $3.2 million, higher data center hosting costs of $1.5 million and higher cloud hosting costs of $0.9 million.

Professional and consulting fees decreased by $3.4 million, primarily due to lower acquisition-related integration consulting fees of $1.0 million, lower audit and tax fees of $1.0 million, lower recruiting fees of $0.9 million, lower consulting costs related to our self-clearing operations of $0.3 million and lower legal expenses of $0.2 million.

36

Occupancy expenses decreased by $0.3 million, primarily due to lower utilities expenses.

Marketing expenses increased by $1.6 million, primarily due to higher advertising and sales-related travel and entertainment costs.

General and administrative expenses increased by $2.6 million, primarily due to higher media subscription costs of $1.0 million, higher travel and entertainment costs of $0.8 million, higher office-related administration costs of $0.6 million, and higher regulatory fees of $0.3 million.

Other Income (Expense)

Our other income (expense) for the six months ended June 30, 2023 and 2022, and the resulting dollar and percentage changes, were as follows:

	Six Months Ended June 30,
	2023			2022			$ Change			% Change
	($ in thousands)
Interest income	$	9,561		$	313		$	9,248		NM
Interest expense		(183	)		(510	)		327			(64.1	)	%
Equity in earnings of unconsolidated affiliate		454			191			263		NM
Other, net		(3,770	)		7,111			(10,881	)	NM
Total other income (expense)	$	6,062		$	7,105		$	(1,043	)		(14.7	)	%
NM - not meaningful

Interest income increased by $9.2 million due to higher interest rates.

Equity in earnings of unconsolidated affiliate represents the proportionate share of net income of our equity method investee.

Other, net decreased by $10.9 million principally due to higher net foreign exchange transaction losses compared to foreign exchange gains in the prior period. Other, net for the six months ended June 30, 2022 included a gain of $1.6 million related to revaluation of contingent consideration payable.

Provision for Income Taxes

The provision for income taxes and effective tax rate for the six months ended June 30, 2023 and 2022 were as follows:

	Six Months Ended June 30,
	2023			2022			$ Change			% Change
	($ in thousands)
Provision for income taxes	$	43,658		$	48,306		$	(4,648	)		(9.6	)	%
Effective tax rate		24.6	%		26.8	%

During the six months ended June 30, 2022, the Company's provision for income taxes included $3.2 million of expense related to a settlement with New York State to resolve the 2010 to 2014 audits. Our consolidated effective tax rate can vary from period to period depending on the geographic mix of our earnings, changes in tax legislation and tax rates and the amount and timing of excess tax benefits related to share-based payments, among other factors.

37

Liquidity and Capital Resources

During the six months ended June 30, 2023, we have met our funding requirements through cash on hand, internally generated funds and short-term borrowings. Cash and cash equivalents and investments totaled $505.5 million as of June 30, 2023. Our investments generally consist of investment-grade corporate bonds and U.S. Treasury securities. We limit the amounts that can be invested in any single issuer and invest in short- to intermediate-term instruments whose fair values are less sensitive to interest rate changes.

In October 2021, we entered into the Credit Agreement, which provides aggregate commitments totaling $500.0 million, consisting of a revolving credit facility and a $5.0 million letter of credit sub-limit for standby letters of credit and a $50.0 million sub-limit for swingline loans. The Credit Agreement will mature on October 15, 2024, with our option to request up to two additional 364-day extensions at the discretion of each lender and subject to customary conditions. As of June 30, 2023, we had $0.1 million in letters of credit outstanding and $499.9 million in available borrowing capacity under the Credit Agreement. The Credit Agreement requires that we satisfy certain covenants, including a requirement to not exceed a maximum consolidated total leverage ratio. We were in compliance with all applicable covenants at June 30, 2023. See Note 11 to the Consolidated Financial Statements for a discussion of the Credit Agreement.

In connection with their self-clearing operations, certain of our operating subsidiaries maintain agreements with their settlement bank to allow the subsidiaries to borrow in the aggregate of up to $500.0 million on an uncommitted basis, collateralized by eligible securities pledged by the subsidiaries to the settlement bank, subject to certain haircuts. Borrowings under these agreements will bear interest at a base rate per annum equal to the higher of the upper range of the Federal Funds Rate, 0.25% or one-month SOFR, plus 1.00%. As of June 30, 2023, the subsidiaries had no borrowings outstanding and up to $500.0 million in available uncommitted borrowing capacity under such agreements. See Note 11 to the Consolidated Financial Statements for a discussion of these agreements.

Under arrangements with their settlement banks, certain of our operating subsidiaries may receive overnight financing in the form of bank overdrafts. As of June 30, 2023, we had no overdrafts payable outstanding.

As a result of our self-clearing and settlement activities, we are required to finance certain transactions, maintain deposits with various clearing organizations and clearing broker-dealers and maintain a special reserve bank account for the benefit of customers pursuant to Rule 15c3-3 of the Exchange Act. As of June 30, 2023, the aggregate amount of the positions financed, deposits and customer reserve balances associated with our self-clearing and settlement activities was $243.4 million. These requirements can fluctuate based on trading activity, market volatility or other factors which may impact our liquidity or require us to use our capital resources.

Cash Flows for the Six Months Ended June 30, 2023 Compared to the Six Months Ended June 30, 2022

Our cash flows were as follows:

	Six Months Ended June 30,
	2023			2022			$ Change		% Change
	($ in thousands)
Net cash provided by operating activities	$	112,921		$	69,907		$	43,014		61.5		%
Net cash (used in) investing activities		(47,767	)		(55,642	)		7,875		(14.2	)
Net cash (used in) financing activities		(87,670	)		(187,048	)		99,378		(53.1	)
Effect of exchange rate changes on cash and    cash equivalents		7,181			(23,894	)		31,075	NM
Net decrease for the period	$	(15,335	)	$	(196,677	)	$	181,342		(92.2	)	%
NM - not meaningful

The $43.0 million increase in net cash flows provided by operating activities was primarily due to a higher change in net receivables from broker-dealers, clearing organizations and customers associated with our clearing activities of $41.6 million, lower accounts receivable of $10.7 million and higher net income of $1.8 million, offset by lower accounts payable, accrued expenses and other liabilities of $10.9 million.

The $7.9 million decrease in net cash used in investing activities was primarily due to a decrease in cash used for equity method investments of $34.4 million and lower purchases of furniture, equipment and leasehold improvements of $1.4 million, offset by higher net purchases of available-for-sale investments of $24.8 million and higher capitalization of software development costs of $3.2 million.

The $99.4 million decrease in net cash used in financing activities was principally due to lower repurchases of common stock of $87.5 million, lower cash used in the payment of contingent consideration of $13.7 million and higher exercises of stock options of $0.5 million, offset by higher cash dividends of $1.7 million and higher withholding tax payments on restricted stock vesting of $0.7 million.

38

The $31.1 million change in the effect of exchange rate changes on cash and cash equivalents was driven by changes in the cumulative translation adjustment which reflects the weakening of the U.S. dollar during the current period compared to strengthening during the prior year.

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 believe that our current resources are adequate to meet our liquidity needs and requirements, including commitments for capital expenditures, in the short-term (during the next 12 months). However, our future liquidity and capital requirements will depend on a number of factors, including liquidity requirements associated with our self-clearing operations and expenses associated with product development and expansion and new business opportunities that are intended to further diversify our revenue streams. We may also acquire or invest in technologies, business ventures or products that are complementary to our business. In the event we require any additional financing, it will take the form of equity or debt financing. Any additional equity offerings may result in dilution to our stockholders. Any debt financings, 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. In addition, in the long-term (beyond 12 months), we believe our liquidity needs and requirements will be affected by the factors discussed above.

One of our U.S. subsidiaries is registered as a broker-dealer and therefore is subject to the applicable rules and regulations of the SEC and FINRA. These rules contain minimum net capital requirements, as defined in the applicable regulations. Certain of our foreign subsidiaries are regulated by the FCA in the U.K. or other foreign regulators and must maintain financial resources, as defined in the applicable regulations, in excess of the applicable financial resources requirement. As of June 30, 2023, each of our subsidiaries that are subject to these regulations had net capital or financial resources in excess of their minimum requirements. As of June 30, 2023, our subsidiaries maintained aggregate net capital and financial resources that were $550.0 million in excess of the required levels of $29.0 million.

Each of our U.S. and foreign regulated subsidiaries are subject to local regulations which generally limit, or require the prior notification to or approval from such regulated entity’s principal regulator before, the repayment of borrowings from our affiliates, paying cash dividends, making loans to our affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources. As of June 30, 2023, the amount of unrestricted cash held by our non-U.S. subsidiaries was $210.1 million.

We execute securities transactions between our institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller in trades. Our operating subsidiaries settle such transactions pursuant to their self-clearing operations or through the use of third-party clearing brokers or settlement agents. Settlement typically occurs within one to two trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded. Under both the self-clearing and the third-party clearing models, we may be exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction or if there is an error in executing a matched principal transaction. Pursuant to the terms of the securities clearing agreements, each third-party clearing broker has the right to charge us for any losses they suffer resulting from a counterparty’s failure on any of our trades. We did not record any liabilities or losses with regard to counterparty failures for the six months ended June 30, 2023 and 2022. Substantially all of our open securities failed-to-deliver and securities failed-to-receive transactions as of June 30, 2023 have subsequently settled at the contractual amounts.

In the normal course of business, we enter into contracts that contain a variety of representations, warranties and indemnification provisions. Our maximum exposure from any claims under these arrangements is unknown, as this would involve claims that have not yet occurred. However, based on experience, the Company expects the risk of material loss to be remote.

We have operating leases for corporate offices with initial lease terms ranging from one year to 15 years. We have total future contractual rent payments on these leases of $107.6 million, with $11.4 million due within the next 12 months and $96.2 million due beyond 12 months.

We enter into foreign currency forward contracts to economically hedge our exposure to variability in certain foreign currency transaction gains and losses. As of June 30, 2023, the notional value of our foreign currency forward contract outstanding was $62.9 million and the fair value of the asset was $0.6 million.

In January 2021, our Board authorized a share repurchase program for up to $100.0 million that commenced in April 2021 and was exhausted in January 2022. In January 2022, our Board authorized a share repurchase program for up to $150.0 million that commenced in March 2022. Shares repurchased under the program will be held in treasury for future use. As of June 30, 2023, we had $100.0 million of remaining capacity under the program.

In July 2023, our Board of Directors approved a quarterly cash dividend of $0.72 per share payable on August 16, 2023 to stockholders of record as of the close of business on August 2, 2023. Any future declaration and payment of dividends will be at the sole discretion of our Board of Directors.

39

Non-GAAP Financial Measures

In addition to reporting financial results in accordance with GAAP, we use certain non-GAAP financial measures: earnings before interest, taxes, depreciation and amortization (“EBITDA”), EBITDA margin and free cash flow. Starting with the first quarter of 2023, our calculation of EBITDA has been revised to adjust for interest income in addition to interest expense. In prior periods, we only adjusted for interest expense because interest income amounts were insignificant. Prior comparable periods have now been recast to conform to the current presentation. Likewise, starting with the first quarter of 2023, EBITDA margin is calculated by adjusting for interest income in addition to interest expense and prior comparable periods have been recast to conform to the current presentation. We define EBITDA margin as EBITDA divided by revenues. We define free cash flow as cash flow from operating activities excluding the net change in trading investments and net change in securities failed-to-deliver and securities failed-to-receive from broker-dealers, clearing organizations and customers, less expenditures for furniture, equipment and leasehold improvements and capitalized software development costs. We believe these non-GAAP financial measures, when taken into consideration with the corresponding GAAP financial measures, are important in understanding our operating results. EBITDA, EBITDA margin and free cash flow are not measures of financial performance or liquidity under GAAP and therefore should not be considered an alternative to net income or cash flow from operating activities as an indicator of operating performance or liquidity. We believe that that that these non-GAAP financial measures, when taken into consideration with the corresponding GAAP financial measures, provide additional information regarding our operating results because they assist both investors and management in analyzing and evaluating the performance of our business.

The table set forth below presents a reconciliation of our net income to EBITDA and net income margin to EBITDA margin, as defined above, for the three and six months ended June 30, 2023 and 2022:

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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

Market Risk

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, 2023, we had $73.9 million of investments in U.S. Treasuries that were classified as trading securities and $24.7 million of investments in corporate bonds that were classified as available-for-sale. Adverse movements, such as a decrease in the value of these securities or a downturn or disruption in the markets for these securities, could result in a substantial loss. A 10% decrease in the market value of our U.S Treasuries or available-for-sale investments would result in losses of approximately $7.4 million and $2.5 million, respectively. 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.

Interest Rate Risk

Interest rate risk represents our exposure to interest rate changes with respect to our cash and cash equivalents, restricted cash and deposits. As of June 30, 2023, our cash and cash equivalents, restricted cash and deposits amounted to $557.3 million. A hypothetical 100 basis point change in interest rates would increase or decrease our annual interest income by approximately $5.6 million, assuming no change in the amount or composition of our cash and cash equivalents, restricted cash and deposits.

As of June 30, 2023, a hypothetical 100 basis point increase or decrease in interest rates would decrease or increase the fair value of the available-for-sale investment portfolio by approximately $0.3 million, assuming no change in the amount or composition of the investments. The hypothetical unrealized gain (loss) of $0.3 million would be recognized in accumulated other comprehensive loss on the Consolidated Statements of Financial Condition.

A similar hypothetical 100 basis point increase or decrease in interest rates would decrease or increase the fair value of the trading securities portfolio by approximately $1.0 million. The hypothetical unrealized gain (loss) of $1.0 million would be recognized in other, net in the Consolidated Statements of Operations.

We do not maintain an inventory of bonds that are traded on our platform.

Foreign Currency Exchange Rate Risk

We conduct operations in several different countries outside of the U.S., most notably the U.K., and substantial portions of our revenues, expenses, assets and liabilities are generated and denominated in non U.S. dollar currencies. Since our consolidated financial statements are presented in U.S. dollars, we must translate revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Accordingly, increases or decreases in the value of the U.S. dollar against the other currencies will affect our net operating revenues, operating expenses, operating income and the value of balance sheet items denominated in foreign currencies.

During the twelve months ended June 30, 2023, approximately 15.1% of our revenue and 26.2% of our expenses were denominated in currencies other than the U.S. dollar, most notably the British Pound Sterling. Based on actual results over the past year, a hypothetical 10% increase or decrease in the U.S. dollar against all other currencies would have increased or decreased revenue by approximately $11.1 million and operating expenses by approximately $10.7 million.

41

Credit Risk

Through certain of our subsidiaries, we execute securities transactions between our institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller in trades. Our operating subsidiaries settle such transactions pursuant to their self-clearing operations or through the use of third-party clearing brokers or settlement agents. Settlement typically occurs within one to two 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 and performance risks in our role as matched principal trading counterparty to our clients executing bond trades on our platform, including the risk that counterparties that owe us money or securities 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. In connection with Open Trading or other anonymous protocols, we expect that the number of transactions in which we act as a matched principal will increase.

We have policies, procedures and automated controls in place to identify and manage our credit risk. There can be no assurance that these policies, procedures and automated controls will effectively mitigate our credit risk exposure. Some of our risk management procedures are reliant upon the evaluation of information regarding the fixed-income markets, our clients or other relevant matters that are publicly available or otherwise acquired from third party sources. Such information may not be accurate, complete, up-to-date or properly assessed and interpreted by us. If our risk management procedures fail, our business, financial condition and results of operations may be adversely affected. Furthermore, our insurance policies are unlikely to provide coverage for such risks.

Cash and cash equivalents include cash and money market instruments that are primarily maintained at three major global banks. Given this concentration, we are exposed to certain credit risk in relation to our deposits at these banks.

Derivative Risk

Our limited derivative risk stems from our activities in the foreign currency forward contract market. We use this market to economically hedge our foreign exchange gains and losses on the Consolidated Statements of Operations that arise from our U.S. dollar versus British Pound Sterling exposure from the activities of our U.K. subsidiaries. As of June 30, 2023, the fair value of the notional amount of our foreign currency forward contract was $63.5 million. We do not hold derivative instruments for purposes other than economically hedging foreign currency risk.

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 Exchange Act, as of June 30, 2023. 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, 2023 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.

PART II — Other Information

It is not presently possible to determine our ultimate exposure to these matters and there is no assurance that the resolution of the outstanding matters will not significantly exceed any reserves accrued by us. See Note 13 to the Consolidated Financial Statements for a discussion of our commitments and contingencies.

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, 2022. The consolidated financial information as of December 31, 2022 has been derived from audited financial statements not included herein. These unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) 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

The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Investments

The Company determines the appropriate classification of securities at the time of purchase which are recorded in the Consolidated Statements of Financial Condition on the trade date. Securities are classified as available-for-sale or trading. Available-for-sale investments are carried at fair value with unrealized gains or losses reported in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition and realized gains or losses reported in other, net in the Consolidated Statements of Operations. Trading investments include U.S. Treasuries and are carried at fair value, with realized and unrealized gains or losses included in other, net in the Consolidated Statements of Operations.

The Company assesses whether an impairment loss on its available-for-sale debt securities has occurred due to declines in fair value or other market conditions. When the amortized cost basis of an available-for-sale debt security exceeds its fair value, the security is deemed to be impaired. The portion of an impairment related to credit losses is determined by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security and is recorded as a charge in the Consolidated Statements of Operations. The remainder of an impairment 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.

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, trading securities, available-for-sale securities, foreign currency forward contracts and contingent consideration payables associated with acquisitions. All other financial instruments are short-term in nature and the carrying amounts reported on the Consolidated Statements of Financial Condition approximate fair value.

Receivables from and Payables to Broker-dealers, Clearing Organizations and Customers

Receivables from broker-dealers, clearing organizations and customers include amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (“securities failed-to-deliver”) and cash deposits held at clearing organizations and clearing brokers to facilitate the settlement and clearance of matched principal transactions. Payables to broker-dealers, clearing organizations and customers include amounts payable for securities not received by the Company from a seller by the settlement date (“securities failed-to-receive”). Securities failed-to-deliver and securities failed-to-receive for transactions executed on a matched principal basis where the Company serves as a counterparty to both the buyer and the seller are recorded on a settlement date basis. The Company presents its securities failed-to-deliver and securities failed-to-receive balances on a net-by-counterparty basis within receivables from and payables to broker-dealers, clearing organizations and customers. The difference between the Company’s trade-date receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade date basis.

Allowance for Credit Losses

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 credit losses is based on an estimate of the amount of potential credit losses in existing accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific collection issues that have been identified. Account balances are grouped for evaluation based on various risk characteristics, including billing type, legal entity, and geographic region. Additions to the allowance for credit losses are charged to bad debt expense, which is included in general and administrative expense in the Company’s Consolidated Statements of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses.

The allowance for credit losses was $0.4 million and $0.6 million as of June 30, 2023 and December 31, 2022, respectively. The provision for bad debts, write-offs and other charges against the allowance for credit losses were immaterial for the three and six months ended June 30, 2023 and 2022.

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. The Company amortizes leasehold improvements on a straight-line basis 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, including, among other items, employee compensation and related benefits and third-party consulting costs at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. 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.

Cloud Computing Costs

The Company capitalizes certain costs associated with cloud computing arrangements, including, among other items, vendor software development costs billed to us that are part of the application development stage. These costs are recorded as a prepaid asset on the Consolidated Statements of Financial Condition and are amortized over the period of the hosting service contract, which ranges from one to five years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Foreign Currency 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 other, net in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to economically hedge its foreign currency transaction gains and losses. Realized and unrealized gains and losses on these forward contracts are included in other, net in the Consolidated Statements of Operations. The Company records the fair value of the forward contract asset in prepaid expenses and other assets or the fair value of the forward contract liability in accounts payable, accrued expenses and other liabilities in the Consolidated Statements of Financial Condition.

Revenue Recognition

The Company’s classification of revenues in the Consolidated Statements of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has four revenue streams as described below.

Commission Revenue – The Company charges its broker-dealer clients variable transaction fees for trades executed on its platforms and, under certain plans, distribution fees or monthly minimum fees to use the platforms for a particular product area. Variable transaction fees are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on the platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. Bonds that are more actively traded or that have shorter maturities generally generate lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. Under the Company’s disclosed trading transaction fee plans, variable transaction fees, distribution fees and unused monthly fee commitments are invoiced and recorded on a monthly basis.

For Open Trading trades that the Company executes between and among institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller, the Company earns its commission through the difference in price between the two trades. The commission is collected upon settlement of the trade, which typically occurs within one to two trading days after the trade date. For the majority of the Company’s U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis. The following table presents commission revenue by fee type:

	Three Months Ended June 30,				Six Months Ended June 30,

Total commissions	$	158,586	$	163,463	$	340,577	$	329,576

Information services – Information services includes data licensed to the Company’s broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. The nature and timing of each performance obligation may vary as these contracts are either subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services that are transferred at a point in time. Revenues for services transferred over time are recognized ratably over the contract period as the Company’s performance obligation is met, whereas revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period. The following table presents information services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Information services revenue by timing of recognition
Services transferred over time	$	11,487	$	9,223	$	22,146	$	18,708

Total information services revenues	$	11,655	$	9,396	$	22,665	$	19,205

Post-trade services – Post-trade services revenue is generated from regulatory transaction reporting, trade publication and trade matching services. Customers are generally billed monthly in arrears and revenue is recognized in the period transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. The Company also generates one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is completed. The following table presents post-trade services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Post-trade services revenue by timing of recognition
Services transferred over time	$	9,397	$	9,143	$	19,352	$	19,014

Total post-trade services revenues	$	9,415	$	9,144	$	19,395	$	19,056

Other revenues – Other revenues primarily includes revenue from telecommunications line charges to broker-dealer clients.

Contract liabilities consist of deferred revenues that the Company records when cash payments are received or due in advance of services to be performed. The revenue recognized from contract liabilities and the remaining balance is shown below:

	December 31, 2022		Payments received in advance of services to be performed		Revenue recognized for services performed during the period			Foreign Currency Translation		June 30, 2023
	(In thousands)
Information services	$	3,121	$	5,891	$	(6,108	)	$	—	$	2,904
Post-trade services		869		12,359		(11,867	)		39		1,400
Total deferred revenue	$	3,990	$	18,250	$	(17,975	)	$	39	$	4,304

The majority of the Company’s information services and post-trade services contracts are short-term in nature with durations of less than one year. For contracts with original durations extending beyond one year, the aggregate amount of the transaction price allocated to remaining performance obligations was $59.3 million as of June 30, 2023. The Company expects to recognize revenue associated with the remaining performance obligations over the next 49 months.

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. Forfeitures are recognized as they occur.

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. Tax benefits for uncertain tax positions are recognized when it is more likely than not that the positions will be sustained upon examination based on their technical merits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statements of Operations. All tax effects related to share-based payments are recorded in the provision for income taxes in the periods during which the awards are exercised or vest.

Business Combinations, Goodwill and Intangible Assets

Business combinations 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 requires judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates, customer attrition rates and asset lives.

The Company operates as a single reporting unit. Following an acquisition, goodwill no longer retains its identification with a particular acquisition, but instead becomes identifiable with the entire reporting unit. As a result, all of the fair value of the Company is available to support the value of goodwill. An impairment review of goodwill is performed on an annual basis, at year-end, or more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives which range from one to 15 years using either a straight-line or accelerated amortization method based on the pattern of economic benefit the Company expects to realize from such assets. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Equity Investments and Consolidation

The Company evaluates equity investments for potential consolidation under the voting-interest or variable-interest models. The Company consolidates investees over which the Company determines it has control under the voting interest model, generally greater than 50% ownership, or for which the Company is the primary beneficiary under the variable-interest model. The Company uses the equity method of accounting when it exercises significant influence over the investee, but does not have operating control, generally between 20% and 50% ownership. Under the equity method of accounting, original investments are recorded at cost in prepaid expenses and other assets on the Consolidated Statements of Financial Condition and adjusted by the Company’s proportionate share of the investees’ undistributed earnings or losses. Equity investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

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 GAAP 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.

Regulatory Capital Requirements

3. Regulatory Capital Requirements

One of the Company’s U.S. subsidiaries is registered as a broker-dealer and therefore is subject to the applicable rules and regulations of the SEC and the Financial Industry Regulatory Authority (“FINRA”). These rules contain minimum net capital requirements, as defined in the applicable regulations. Certain of the Company’s foreign subsidiaries are regulated by the Financial Conduct Authority (“FCA”) in the U.K. or other foreign regulators and must maintain financial resources, as defined in the applicable regulations, in excess of the applicable financial resources requirement. As of June 30, 2023, each of the Company’s subsidiaries that are subject to these regulations had net capital or financial resources in excess of their minimum requirements. As of June 30, 2023, the Company’s subsidiaries maintained aggregate net capital and financial resources that were $550.0 million in excess of the required levels of $29.0 million.

The Company’s U.S. broker-dealer subsidiary is required to segregate funds in a special reserve bank account for the benefit of customers pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As of June 30, 2023, the U.S. broker-dealer subsidiary had a balance of $52.0 million in its special reserve bank account. This U.S. broker-dealer subsidiary also maintained net capital that was $330.2 million in excess of the required level of $3.7 million.

Each of the Company’s U.S. and foreign regulated subsidiaries are subject to local regulations which generally limit, or require the prior notification to or approval from such regulated entity’s principal regulator before, the repayment of borrowings from the Company or affiliates, paying cash dividends, making loans to the Company or affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources.

Money market funds are included in cash and cash equivalents on the Consolidated Statements of Financial Condition. 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 contracts are classified within Level 2 as the valuation inputs are based on quoted market prices. The mutual funds held in a rabbi trust represent investments associated with the Company’s deferred cash incentive plan.

Liabilities classified within Level 3 reflect contingent consideration payable recognized in connection with acquisitions. During the three months ended June 30, 2023, the Company made final payment on the remaining contingent consideration. The following table summarizes the change in the Company's Level 3 liabilities for the six months ended June 30, 2023:

11. Credit Agreements and Short-term Financing

Credit Agreement

On October 15, 2021, the Company entered into a three-year revolving credit facility (the “Credit Agreement”) provided by a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent, which provides aggregate commitments totaling $500.0 million, consisting of a revolving credit facility and a $5.0 million letter of credit sub-limit for standby letters of credit and a $50.0 million sub-limit for swingline loans. The Credit Agreement will mature on October 15, 2024, with the Company's option to request up to two additional 364-day extensions at the discretion of each lender and subject to customary conditions. Subject to satisfaction of certain specified conditions, the Company is permitted to upsize the Credit Agreement by up to $250.0 million in total.

Borrowings under the Credit Agreement bore interest at a rate per annum equal to the base rate or adjusted LIBOR plus an applicable margin that varies with the Company’s consolidated total leverage ratio. On March 28, 2023, the Company entered into a first amendment to the Credit Agreement, which among other things, established customary Secured Overnight Financing Rate (“SOFR”) provisions in lieu of the London Interbank Offered Rate (“LIBOR”) provisions set forth in the Credit Agreement. Following such amendment, borrowings under the Credit Agreement will bear interest at a rate per annum equal to the alternate base rate or the adjusted term SOFR rate, plus an applicable margin that varies with the Company’s consolidated total leverage ratio.

The Credit Agreement requires that the Company satisfy certain covenants, including a requirement to not exceed a maximum consolidated total leverage ratio. As of June 30, 2023, the Company had $0.1 million in letters of credit outstanding and $499.9 million in available borrowing capacity under the Credit Agreement. The Company incurred interest expense under the Credit Agreement of $0.1 million and $0.2 million for the three months ended June 30, 2023 and 2022, respectively, and $0.1 million and $0.3 million for the six months ended June 30, 2023 and 2022, respectively.

Uncommitted Collateralized Agreements

In connection with their self-clearing operations, certain of the Company’s U.S. and U.K. operating subsidiaries maintain agreements with their settlement bank to allow the subsidiaries to borrow in the aggregate of up to $500.0 million on an uncommitted basis, collateralized by eligible securities pledged by the subsidiaries to the settlement bank, subject to certain haircuts. Borrowings under these agreements will bear interest at a base rate per annum equal to the higher of the upper range of the Federal Funds Rate, 0.25% or one-month SOFR, plus 1.00%.

The Company incurred no interest expense on borrowings under such agreements during the three months ended June 30, 2023 and $0.1 million of interest expense during six months ended June 30, 2023. The Company incurred no interest expense on borrowings under such agreements during the three and six months ended June 30, 2022. As of June 30, 2023, the Company had no borrowings outstanding and up to $500.0 million in available uncommitted borrowing capacity under such agreements.

Short-term Financing

Under arrangements with their settlement banks, certain of the Company’s U.S. and U.K. operating subsidiaries may receive overnight financing in the form of bank overdrafts. The Company incurred interest expense on such overnight financing of $0.1 million during each of the three months ended June 30, 2023 and 2022, and $0.1 million and $0.2 million of interest expense during the six months ended June 30, 2023 and 2022, respectively.

12. Leases

The Company has operating leases for corporate offices with initial lease terms ranging from one year to 15 years. Certain leases contain options to extend the initial term at the Company’s discretion. The Company accounts for the option to extend when it is reasonably certain of being exercised. The Company’s lease agreements do not contain any material residual value guarantees, restrictions or covenants.

The following table presents the components of lease expense for the three and six months ended June 30, 2023 and 2022:

		Three Months Ended June 30,					Six Months Ended June 30,

Net lease cost		$	3,229	$	3,347		$	6,391	$	6,730

The Company determines whether an arrangement is, or includes, a lease at contract inception. Operating lease right-of-use assets and liabilities are recognized at commencement date and are initially measured based on the present value of lease payments over the defined lease term. As the Company's leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at the adoption date in determining the present value of lease payments.

The weighted average remaining lease term and weighted average discount rate are as follows:

	As of
Lease Term and Discount Rate	June 30, 2023			December 31, 2022
Weighted average remaining lease term (in years)		10.2			10.6

Commitments and Contingencies

13. Commitments and Contingencies

Legal

In the normal course of business, the Company and its subsidiaries included in the consolidated financial statements may be involved in various lawsuits, proceedings and regulatory examinations. The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings, if any, utilizing the latest information available. For matters where it is probable that the Company will incur a material loss and the amount can be reasonably estimated, the Company will establish an accrual for the loss. Once established, the accrual will be adjusted to reflect any relevant developments. When a loss contingency is not both probable and estimable, the Company does not establish an accrual.

Based on currently available information, the outcome of the Company’s outstanding matters is not expected to have a material adverse impact on the Company’s financial position. It is not presently possible to determine the ultimate exposure to these matters and there is no assurance that the resolution of the outstanding matters will not significantly exceed any reserves accrued by the Company.

Other

The Company, through certain of its subsidiaries, executes securities transactions between its institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller in trades. The Company’s operating subsidiaries settle such transactions pursuant to their self-clearing operations or through the use of third-party clearing brokers or settlement agents. Settlement typically occurs within one to two trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded. Under both the self-clearing and the third-party clearing models, the Company may be exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction or if there is an error in executing a matched principal transaction. Pursuant to the terms of the securities clearing agreements, each third-party clearing broker has the right to charge the Company for any losses they suffer resulting from a counterparty’s failure on any of the Company’s trades. The Company did not record any liabilities or losses with regard to counterparty failures for the six months ended June 30, 2023 and 2022.

In the normal course of business, the Company enters into contracts that contain a variety of representations, warranties and indemnification provisions. 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 material loss to be remote.

The Company considers its operations to constitute a single business segment because of the highly integrated nature of these products and services, the financial markets in which the Company competes and the Company’s worldwide business activities. The Company believes that results by geographic region or client sector are not necessarily meaningful in understanding its business.

For the six months ended June 30, 2023 and 2022, the U.K. was the only individual foreign country in which the Company had a subsidiary that accounted for 10% or more of the total revenues or total long-lived assets. Revenues and long-lived assets are attributed to a geographic area based on the location of the particular subsidiary. Long-lived assets are defined as furniture, equipment, leasehold improvements and capitalized software. Revenues for the three and six months ended June 30, 2023 and 2022 and long-lived assets as of June 30, 2023 and December 31, 2022 were as follows:

Accounting Policies [Abstract]

Basis of Presentation

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, 2022. The consolidated financial information as of December 31, 2022 has been derived from audited financial statements not included herein. These unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) 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

The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Investments

Investments

The Company determines the appropriate classification of securities at the time of purchase which are recorded in the Consolidated Statements of Financial Condition on the trade date. Securities are classified as available-for-sale or trading. Available-for-sale investments are carried at fair value with unrealized gains or losses reported in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition and realized gains or losses reported in other, net in the Consolidated Statements of Operations. Trading investments include U.S. Treasuries and are carried at fair value, with realized and unrealized gains or losses included in other, net in the Consolidated Statements of Operations.

The Company assesses whether an impairment loss on its available-for-sale debt securities has occurred due to declines in fair value or other market conditions. When the amortized cost basis of an available-for-sale debt security exceeds its fair value, the security is deemed to be impaired. The portion of an impairment related to credit losses is determined by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security and is recorded as a charge in the Consolidated Statements of Operations. The remainder of an impairment 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.

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, trading securities, available-for-sale securities, foreign currency forward contracts and contingent consideration payables associated with acquisitions. All other financial instruments are short-term in nature and the carrying amounts reported on the Consolidated Statements of Financial Condition approximate fair value.

Receivables from and Payables to Broker - dealers, Clearing Organizations and Customers

Receivables from and Payables to Broker-dealers, Clearing Organizations and Customers

Receivables from broker-dealers, clearing organizations and customers include amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (“securities failed-to-deliver”) and cash deposits held at clearing organizations and clearing brokers to facilitate the settlement and clearance of matched principal transactions. Payables to broker-dealers, clearing organizations and customers include amounts payable for securities not received by the Company from a seller by the settlement date (“securities failed-to-receive”). Securities failed-to-deliver and securities failed-to-receive for transactions executed on a matched principal basis where the Company serves as a counterparty to both the buyer and the seller are recorded on a settlement date basis. The Company presents its securities failed-to-deliver and securities failed-to-receive balances on a net-by-counterparty basis within receivables from and payables to broker-dealers, clearing organizations and customers. The difference between the Company’s trade-date receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade date basis.

Allowance for Credit Losses

Allowance for Credit Losses

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 credit losses is based on an estimate of the amount of potential credit losses in existing accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific collection issues that have been identified. Account balances are grouped for evaluation based on various risk characteristics, including billing type, legal entity, and geographic region. Additions to the allowance for credit losses are charged to bad debt expense, which is included in general and administrative expense in the Company’s Consolidated Statements of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses.

The allowance for credit losses was $0.4 million and $0.6 million as of June 30, 2023 and December 31, 2022, respectively. The provision for bad debts, write-offs and other charges against the allowance for credit losses were immaterial for the three and six months ended June 30, 2023 and 2022.

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. The Company amortizes leasehold improvements on a straight-line basis 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, including, among other items, employee compensation and related benefits and third-party consulting costs at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. 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.

Cloud Computing Costs

Cloud Computing Costs

The Company capitalizes certain costs associated with cloud computing arrangements, including, among other items, vendor software development costs billed to us that are part of the application development stage. These costs are recorded as a prepaid asset on the Consolidated Statements of Financial Condition and are amortized over the period of the hosting service contract, which ranges from one to five years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Foreign Currency 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 other, net in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to economically hedge its foreign currency transaction gains and losses. Realized and unrealized gains and losses on these forward contracts are included in other, net in the Consolidated Statements of Operations. The Company records the fair value of the forward contract asset in prepaid expenses and other assets or the fair value of the forward contract liability in accounts payable, accrued expenses and other liabilities in the Consolidated Statements of Financial Condition.

Revenue Recognition

Revenue Recognition

The Company’s classification of revenues in the Consolidated Statements of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has four revenue streams as described below.

Commission Revenue – The Company charges its broker-dealer clients variable transaction fees for trades executed on its platforms and, under certain plans, distribution fees or monthly minimum fees to use the platforms for a particular product area. Variable transaction fees are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on the platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. Bonds that are more actively traded or that have shorter maturities generally generate lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. Under the Company’s disclosed trading transaction fee plans, variable transaction fees, distribution fees and unused monthly fee commitments are invoiced and recorded on a monthly basis.

For Open Trading trades that the Company executes between and among institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller, the Company earns its commission through the difference in price between the two trades. The commission is collected upon settlement of the trade, which typically occurs within one to two trading days after the trade date. For the majority of the Company’s U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis. The following table presents commission revenue by fee type:

	Three Months Ended June 30,				Six Months Ended June 30,

Total commissions	$	158,586	$	163,463	$	340,577	$	329,576

Information services – Information services includes data licensed to the Company’s broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. The nature and timing of each performance obligation may vary as these contracts are either subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services that are transferred at a point in time. Revenues for services transferred over time are recognized ratably over the contract period as the Company’s performance obligation is met, whereas revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period. The following table presents information services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Information services revenue by timing of recognition
Services transferred over time	$	11,487	$	9,223	$	22,146	$	18,708

Total information services revenues	$	11,655	$	9,396	$	22,665	$	19,205

Post-trade services – Post-trade services revenue is generated from regulatory transaction reporting, trade publication and trade matching services. Customers are generally billed monthly in arrears and revenue is recognized in the period transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. The Company also generates one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is completed. The following table presents post-trade services revenue by timing of recognition:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Post-trade services revenue by timing of recognition
Services transferred over time	$	9,397	$	9,143	$	19,352	$	19,014

Total post-trade services revenues	$	9,415	$	9,144	$	19,395	$	19,056

Other revenues – Other revenues primarily includes revenue from telecommunications line charges to broker-dealer clients.

Contract liabilities consist of deferred revenues that the Company records when cash payments are received or due in advance of services to be performed. The revenue recognized from contract liabilities and the remaining balance is shown below:

	December 31, 2022		Payments received in advance of services to be performed		Revenue recognized for services performed during the period			Foreign Currency Translation		June 30, 2023
	(In thousands)
Information services	$	3,121	$	5,891	$	(6,108	)	$	—	$	2,904
Post-trade services		869		12,359		(11,867	)		39		1,400
Total deferred revenue	$	3,990	$	18,250	$	(17,975	)	$	39	$	4,304

The majority of the Company’s information services and post-trade services contracts are short-term in nature with durations of less than one year. For contracts with original durations extending beyond one year, the aggregate amount of the transaction price allocated to remaining performance obligations was $59.3 million as of June 30, 2023. The Company expects to recognize revenue associated with the remaining performance obligations over the next 49 months.

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. Forfeitures are recognized as they occur.

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. Tax benefits for uncertain tax positions are recognized when it is more likely than not that the positions will be sustained upon examination based on their technical merits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statements of Operations. All tax effects related to share-based payments are recorded in the provision for income taxes in the periods during which the awards are exercised or vest.

Business Combinations, Goodwill and Intangible Assets

Business Combinations, Goodwill and Intangible Assets

Business combinations 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 requires judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates, customer attrition rates and asset lives.

The Company operates as a single reporting unit. Following an acquisition, goodwill no longer retains its identification with a particular acquisition, but instead becomes identifiable with the entire reporting unit. As a result, all of the fair value of the Company is available to support the value of goodwill. An impairment review of goodwill is performed on an annual basis, at year-end, or more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives which range from one to 15 years using either a straight-line or accelerated amortization method based on the pattern of economic benefit the Company expects to realize from such assets. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Equity Investments and Consolidation

Equity Investments and Consolidation

The Company evaluates equity investments for potential consolidation under the voting-interest or variable-interest models. The Company consolidates investees over which the Company determines it has control under the voting interest model, generally greater than 50% ownership, or for which the Company is the primary beneficiary under the variable-interest model. The Company uses the equity method of accounting when it exercises significant influence over the investee, but does not have operating control, generally between 20% and 50% ownership. Under the equity method of accounting, original investments are recorded at cost in prepaid expenses and other assets on the Consolidated Statements of Financial Condition and adjusted by the Company’s proportionate share of the investees’ undistributed earnings or losses. Equity investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

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 GAAP 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.
