A substantial part of our working capital may be at risk if a clearing firm defaults on its obligations to our clearing house and its margin and guaranty fund deposits are insufficient to meet its obligations. Additionally, BrokerTec Americas is exposed to the potential risk of loss in the event a counterparty fails to meet its obligations.

Our policies and procedures which are designed to ensure that our clearing firms and other counterparties can satisfy their obligations, including collecting margin and guaranty fund contributions from clearing firms, may not succeed in detecting problems or preventing defaults. The processes for calculating and setting margins and financial safeguards is complex and there is no guarantee that our risk models that are utilized to calculate margin and our financial safeguard procedures will adequately protect us in all circumstances. We have in place various measures intended to enable us to cure any default and maintain liquidity. However, we cannot guarantee that these measures will be sufficient to protect market participants from a default or that we will not be adversely affected in the event of a significant default.

Accounting Policies

Newly Adopted Accounting Policies. In July 2025, the FASB issued an accounting standards update which provides a practical expedient when estimating the amount of expected credit losses on current accounts receivable and current contract assets. This update permits entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the current accounts receivable and current contract assets. Therefore, entities will not need to develop reasonable and supportable forecasts of future economic conditions. The practical expedient must be applied consistently across all current accounts receivable and current contract assets. The company adopted this standard on January 1, 2026, and has elected to apply the practical expedient. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Accounts Receivable. Accounts receivable are comprised of trade receivables and unbilled revenue. All accounts receivable are stated at net realizable value. Exposure to losses on receivables for clearing and transaction fees and other amounts owed by clearing and trading firms is dependent on each firm's financial condition. With respect to clearing firms, our credit loss exposure is mitigated by the memberships that collateralize fees owed to the company. The company retains the right to liquidate exchange memberships to satisfy an outstanding receivable. The allowance for doubtful accounts is calculated based on management's assessment of future expected losses over the life of the receivable, historical trends and the current economic environment within which we operate.
