Significant Accounting Policies #### 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. #### 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 nsaction -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 nd 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. {11}------------------------------------------------ #### 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 -to- ations and clearing brokers to facilitate the settlement and clearance of matched principal transactions.

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 the expected credit losses in 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 was \$617,924 as of December 31, 2025. The provision for credit losses and write-offs against the allowance for credit losses were \$446,041 and \$291,859, respectively, for the year ended December 31, 2025. #### Furniture, Equipment and Leasehold Improvements Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven 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 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. #### Leases At lease commencement, a right-of-use asset and a lease liability are recognized for all leases with an initial term in excess of 12 months based on the initial present value of the fixed lease payments over the lease term. The lease right-of-use asset also reflects the readily te used to discount the lease payments based on the information available at lease commencement.

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 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.

Service agreement fees from affiliates Service agreement fees from affiliates reflect revenues received for services provided to affiliates. Other Revenues cash, deposits and U.S. treasury investments and other miscellaneous income. #### 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 payable to the Parent. 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 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. {14}------------------------------------------------ ### 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 i 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.
