The Board has not yet determined on which committees the Directors-elect will serve in 2027. The Bank expects to compensate the Directors-elect under the 2027 Director Compensation Policy.

Pursuant to the Applicable Regulations, the Bank's member directors, including Member Directors-elect, serve as officers or directors of Bank members. The Bank is a cooperative and conducts business primarily with its members, which are required to own capital stock in the Bank as a prerequisite to transacting certain business with the Bank. Subject to the Act and the Applicable Regulations, the Bank may conduct business with members whose officers or directors serve on the Board, including:

• extending credit in the ordinary course of business to such members, on market terms that are no more favorable to such members than the terms of comparable transactions with other members;

• purchasing short- and long-term investments, at market rates, from such members or their affiliates;

• entering into interest-rate-exchange agreements on market terms with affiliates of such members as counterparties; and

• providing affordable housing benefits in conjunction with such members, or affiliates of such members, on terms and conditions that are no more favorable to such members than the terms and conditions of comparable transactions with other members.

All of the foregoing transactions are made in the ordinary course of the Bank's business and are subject to the same Bank policies as transactions with the Bank's members, housing associates, and third parties generally. For further information, see Item 13 - Certain Relationships and Related Transactions, and Director Independence of the 2025 Annual Report.
