### Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholder of MarketAxess Corporation

#### Opinion on the Financial Statements

We have audited the accompanying statement of financial condition of MarketAxess Corporation (the "Company") as of December 31, 2022, and the related statements of operations, changes in shareholder's equity and cash flows for the year then ended, including the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

#### Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as, evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

### Supplemental Information

The accompanying Supplementary Schedule I - Computation of Net Capital Under Rule 15c3-1 of the Securities and Exchange Commission, Supplementary Schedule II - Computation for Determination of Reserve Requirements Under Rule 15c3-3 of the Securities and Exchange Commission and Supplementary Schedule III - Information Relating to Possession or Control Requirements Under Rule 1503-3 of the Securities and Exchange Commission as of December 31, 2022 (collectively, the "supplemental information") has been subjected to audit procedures performed in conjunction with the audit of the Company's financial statements. The supplemental information is the responsibility of the Company's management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with

#### 1. Organization and Principal Business Activity

Institutional investor and broker-dealer firms use the Company's patented trading technology, accessing global liquidity on its platforms in 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. Through its Open Trading® protocols, the Company executes bond trades between and among institutional investor and broker-dealer clients in the leading all-to-all anonymous trading environment for corporate bonds. The Company also offers a number of trading-related products and services, including: Composite+TM pricing and other market data products to assist clients with trading decisions; auto-execution and other execution services for clients requiring specialized workflow solutions; connectivity solutions that facilitate straight-through processing; and technology services to optimize trading environments. The Company is a wholly-owned subsidiary of MarketAxess Holdings Inc. (the "Parent"), which is a publicly traded company listed on the NASDAQ Global Select Market under the symbol MKTX.

The Company's former subsidiary, LiquidityEdge UK Ltd., was formally liquidated in 2022.

The Company is a broker-dealer registered with the U.S. Securities and Exchange Commission ("SEC") and is a member of the Financial Industry Regulatory Authority ("FINRA").

#### 2. Significant Accounting Policies

#### *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, at Fair Value*

Investments are recorded in the Statement of Financial Condition on the trade date. Investments are carried at fair value, with realized and unrealized gains or losses included in investment gains/(losses) in the Statement of Operations.

#### *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 and trading securities. All other financial instruments are short-term in nature and the carrying amounts reported on the Statement 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 tradedate receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade-date basis.

{11}------------------------------------------------

#### *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 Statement of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses. The allowance for credit losses, the provision for credit losses and write-offs against the allowance for credit losses were immaterial for the year ended December 31, 2022.

#### *Depreciation and Amortization*

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

#### *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 balance sheet and are amortized over the period of the hosting service contract, which range 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.

#### *Revenue Recognition*

The Company's classification of revenues in the Statement of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has three 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.

{12}------------------------------------------------

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. government bonds matched principal trades, commissions are invoiced and recorded on a monthly basis. The following table presents commission revenue by fee type for the year ended December 31, 2022:

#### Commission revenue by fee type

| Variable transaction fees                            |                   |
|------------------------------------------------------|-------------------|
| Disclosed trading                                    | \$<br>278,645,802 |
| Open Trading -<br>matched principal trading          | 134,650,972       |
| U.S. government bonds -<br>matched principal trading | 16,977,674        |
| Total variable transaction fees                      | 430,274,448       |
| Distribution fees and unused minimum fees            | 123,185,587       |
| Total commissions                                    | \$<br>553,460,035 |

*Information Services* – Information services includes data licensed to the Company's broker-dealer clients, institutional investor clients and data-only subscribers. 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 for the year ended December 31, 2022:

#### Information services revenue by timing of recognition

| Services transferred over time          | \$<br>15,329,016 |
|-----------------------------------------|------------------|
| Services transferred at a point in time | 542,228          |
| Total information services revenues     | \$<br>15,871,244 |

*Other Revenues*– Other revenues primarily includes revenue from telecommunications line charges to broker-dealer clients, revenues received for services provided to affiliates and realized and unrealized gains or losses on trading securities.

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:

|                        |    |                   | Payments received<br>in advance of<br>services to be |    | Revenue recognized<br>for services<br>performed during the |    |                   |  |
|------------------------|----|-------------------|------------------------------------------------------|----|------------------------------------------------------------|----|-------------------|--|
|                        |    | December 31, 2021 | performed                                            |    | period                                                     |    | December 31, 2022 |  |
| Total deferred revenue | \$ | 3,526,548         | \$<br>10,256,742                                     | \$ | (10,663,396)                                               | \$ | 3,119,894         |  |

The majority of the Company's 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 \$30,309,431 as of December 31, 2022. The Company expects to recognize revenue associated with the remaining performance obligations over the next 55 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 Statement of Operations over the requisite service period, which is typically the vesting period, with an offsetting liability to the Parent. Forfeitures are recognized as they occur.

{13}------------------------------------------------

#### *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 Statement 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.

The Company files federal and combined state and local income tax returns with its Parent and U.S. affiliates. Pursuant to a tax sharing agreement between the Company and the Parent, income tax expense recorded by the Company is determined on a separate company basis.

#### *Goodwill and Intangible Assets*

The Company operates as a single reporting unit. 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 customer relationships, 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.

#### *Use of Estimates*

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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.

#### *Credit Risk*

The Company acts as a matched principal counterparty in connection with the Open Trading transactions that it executes between clients. The Company acts as an intermediary in these transactions by serving as counterparty to both the buyer and the seller in trades. 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.

The Company is exposed to credit and performance risks in its role as a matched principal trading counterparty to its Open Trading clients executing bond trades on its platforms, including the risk that counterparties that owe the Company money or securities will not perform their obligations. These parties may default on their obligations 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 the Company's risk. Where the unmatched position or failure to deliver is prolonged, there may also be regulatory capital charges required to be taken by the Company. There can be no assurance that the policies and procedures the Company uses to manage this credit risk will effectively mitigate the credit risk exposure.

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

#### 3. Net Capital and Customer Protection Requirements

Pursuant to Rule 15c3-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act'), the Company is required to maintain minimum net capital, as defined, equal to the greater of \$1,000,000 or 2% of aggregate debit items, as defined. As of December 31, 2022, the Company had net capital of \$317,871,428 which exceeded its required net capital of \$3,723,291 by \$314,148,137.

The Company is required to segregate funds in a special reserve bank account for the benefit of customers pursuant to Rule 15c3- 3 of the Exchange Act. As of December 31, 2022, the Company had a balance of \$50,947,193 in its special reserve bank account.

{14}------------------------------------------------

#### 4. Fair Value Financial Instruments

The following table summarizes the valuation of the Company's assets measured at fair value as categorized based on the hierarchy described in Note 2:

The Company or the Parent files U.S. federal, state, and local income tax returns. During the year ended December 31, 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 Parent 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 Parent cannot estimate when the examinations will conclude or the impact such examinations will have on the Company's Financial Statements, if any. Generally, other than the New York City and New York State audits, the Parent is no longer subject to tax examinations by tax authorities for years prior to 2019.

A reconciliation of the Company's unrecognized tax benefits is as follows:

| Balance at December 31, 2021                                  | \$<br>15,088,101 |
|---------------------------------------------------------------|------------------|
| Increases based on tax positions related to prior periods     | 159,606          |
| Decreases related to cash settlements with taxing authorities | (5,413,106)      |
| Balance at December 31, 2022                                  | \$<br>9,834,601  |

As of December 31, 2022, the Company recorded \$9,834,601 of unrecognized tax benefits which, if recognized, would affect the Company's effective tax rate. Due to the uncertainty related to the timing and potential outcome of the audits, the Company cannot reasonably estimate the amount of the unrecognized tax benefit that could be adjusted in the next 12 months. During the year ended December 31, 2022, the Company recognized \$5,758,219 in penalties and interest. The Company had \$7,930,900 accrued for the payment of interest and penalties at December 31, 2022.

#### 10. Stock-based Compensation Plans

Certain of the Company's employees participate in the Parent's stock incentive 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 Parent. Stock compensation expense related to restricted stock units, performance stock units and stock options was \$13,382,449 and is included in employee compensation and benefits in the Statement of Operations.

#### *Stock Options*

The exercise price of each option granted is equal to the market price of the Parent's common stock on the date of grant. Generally, option grants have provided for vesting over a three or five-year period. Options generally expire in six or ten years from the date of grant. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model ("Black-Scholes"). The determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Parent's stock price as well as assumptions regarding a number of highly complex and subjective variables, including the expected stock price volatility over the term of the awards, the risk-free interest rate, the expected dividend yield rate and the expected term. Expected volatilities are based on historical volatility of the Parent's stock. The risk-free interest rate is based on U.S. Treasury securities with a maturity value approximating the expected term of the option. The dividend yield rate is based on the expected annual dividends to be paid divided by the expected stock price. The expected term represents the period of time that options granted are expected to be outstanding based on actual and projected employee stock option exercise behavior.

{19}------------------------------------------------

The weighted-average fair value for options granted during 2022 was \$104.96. The following table represents the assumptions used for Black-Scholes to determine the per share weighted-average fair value for options granted for the year ended December 31, 2022:

| Expected life (years)   | 5.0   |
|-------------------------|-------|
| Risk-free interest rate | 1.5%  |
| Expected volatility     | 32.6% |
| Expected dividend yield | 0.7%  |

The following table reports stock option activity for the year ended December 31, 2022 and the intrinsic value as of December 31, 2022:

The intrinsic value is the amount by which the closing price of the Parent's common stock on December 31, 2022 of \$278.89 or the price on the day of exercise exceeds the exercise price of the stock options multiplied by the number of shares. As of December 31, 2022, there was \$845,998 of total unrecognized compensation cost related to non-vested stock options. That cost is expected to be recognized over a weighted-average period of 1.6 years.

#### *Service-Based Restricted Stock and Restricted Stock Unit Awards*

The Company's annual compensation program includes share-based compensation awards as a component of certain employees' total compensation. These awards are generally subject to annual vesting requirements over a three-year period beginning at the date of grant, which occurs in the first quarter of each year. Accordingly, the expense is generally amortized over the stated vesting period. In addition, the Parent grants shared-based compensation awards to certain of the Company's employees in conjunction with certain new hires and for retention purposes. These awards generally vest over a three-year period and expense is recognized over the requisite service period.

#### *Performance Equity Awards*

The Parent grants performance equity awards to certain executives and senior managers of the firm as a component of their total compensation and in conjunction with new hires and for retention purposes. Annual performance equity awards generally vest over a three-year period and contain both performance- and service-based elements. The Parent has also granted awards with a five-year vesting period with performance- and service-based elements.

In January 2020 and 2021, annual performance equity awards were granted with three-year performance periods, whereby the final amount that vests will be determined based on the level of achievement by the Parent of certain predetermined metrics, including pre-tax adjusted operating margin and market share for the following three fiscal years, including the year of grant. The final awarded pay-out for the awards granted in 2020 was certified at 98.7% in January 2023. The final awarded pay-out for the awards granted in 2021 will range from zero to 200%. Subject to the grantee's continued service, any performance equity awarded to a participant will vest on the three-year anniversary of the grant date. Compensation expense for the three-year performance shares is measured at the grant date and expensed over the requisite service period with performance target achievement assessed at the end of each reporting period.

{20}------------------------------------------------

In January 2022, annual performance equity awards were granted with three-year performance periods, whereby the final amount that vests will be determined based on the level of achievement by the Parent of certain predetermined metrics, including pre-tax adjusted operating margin, U.S. credit market share, and revenue growth excluding U.S. credit for the following three fiscal years, including the year of grant. The final awarded pay-out for the awards granted in 2022 will range from zero to 200%. Subject to the grantee's continued service, any performance equity awarded to a participant will vest on the three-year anniversary of the grant date. Compensation expense for the three-year performance shares is measured at the grant date and expensed over the requisite service period with performance target achievement assessed at the end of each reporting period.

In March 2022, the new Chief Information Officer received a performance equity award of 3,986 target shares. The award is substantially similar to the annual bonus performance equity awards granted in January 2022. The award will fully vest on March 1, 2025 after certification of the performance criteria, subject to continued employment by the Chief Information Officer through such date.

The following table reports the Company's performance payout estimates for three-year performance period awards at December 31, 2022, as well as the target and maximum share payouts for each award date granted:

| 2022             |          |        |         |

As of December 31, 2022, there was \$18,150,198 of total unrecognized compensation expense related to non-vested restricted stock and performance shares. That cost is expected to be recognized over a weighted-average period of 1.7 years.

#### *Employee Stock Purchase Plan*

The Parent previously maintained the MarketAxess Holdings Inc. 2015 Employee Stock Purchase Plan (the "Prior ESPP"), a nonqualified employee stock purchase plan for non-executive employees. Under the plan, participants were granted the right to purchase shares of the Parent's common stock based on the fair market value on the last day of the six-month offering period. On the purchase date, the Parent granted to the participants a number of restricted stock units equal to 20% of the aggregate shares purchased by the participant. These matching restricted stock units vested over a one-year period. The Parent issued 483 matching restricted stock units in connection with the plan for the year ended December 31, 2022. In January 2022, the Parent's Compensation & Talent Committee terminated the Prior ESPP with an effective date of February 28, 2022.

In June 2022, the Parent's stockholders approved the MarketAxess Holdings Inc. 2022 Employee Stock Purchase Plan (the "ESPP") pursuant to which a total of 121,221 shares of the Parent's common stock will be made available for purchase by employees. The ESPP is intended to qualify as an "employee stock purchase plan" meeting the requirements of Section 423 of the Internal Revenue Code. The ESPP was adopted by the Parent's Board of Directors in April 2022 and approved by the Parent's stockholders in June 2022. 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. Purchase dates occur on the first trading day on or after February 15 and August 15 of each year and 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 first offering period under the ESPP began on August 16, 2022.

{21}------------------------------------------------

#### 11. Borrowings, Commitments and Contingencies

#### *Collateralized Agreement*

In connection with its self-clearing operations, the Company has entered into an agreement (the "Collateralized Agreement") with its settlement bank to provide loans to the subsidiary in amounts up to an aggregate of \$200,000,000 on an uncommitted basis. Borrowings under the Collateralized Agreement are collateralized by securities pledged by the Company to the settlement bank, subject to applicable haircuts and concentration limits. Borrowings under the Collateralized Agreement 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 Secured Overnight Financing Rate ("SOFR"), plus 1.00%. The Company did not incur any interest expense on borrowings under the Collateralized Agreement during the year ended December 31, 2022.

#### 12. Retirement and Deferred Compensation Plans

The Parent offers the Company's employees the opportunity to participate in a defined contribution 401(k) plan (the "401(k) Plan"). Participation in the 401(k) Plan is available to all full-time employees of the Company. The Company made \$3,767,247 in matching contributions to the 401(k) Plan for the year ended December 31, 2022.

The Parent offers a non-qualified deferred cash incentive plan to certain officers and other employees. Under the plan, eligible employees may defer up to 100% of their annual cash incentive pay. The Parent has elected to fund its deferred compensation obligations through a rabbi trust. The rabbi trust is subject to creditor claims in the event of insolvency, but such assets are not available for general corporate purposes. Assets held in the rabbi trust are invested in mutual funds, as selected by the participants, which are designated as trading securities and carried at fair value. As of December 31, 2022, the fair value of the mutual fund investments and deferred compensation obligation was \$4,038,869. Changes in the fair value of securities held in the rabbi trust are recognized as trading gains and losses and included in other revenues and offsetting increases or decreases in the deferred compensation obligation are recorded in employee compensation and benefits. For the year ended December 31, 2022, the trading losses were \$1,063,457 with the offsetting impact included in employee compensation and benefits.
