[1] Amounts represent the impact of legally enforceable master netting agreements or other legally enforceable arrangements between the Bank and its derivative counterparties that allow the Bank to offset positive and negative positions as well as any cash collateral held or placed with those same counterparties.
[2] Any overcollateralization or any excess variation margin associated with daily settled contracts at an individual clearinghouse/clearing member or bilateral counterparty level is not included in the determination of the net unsecured amount.
[3] collateral pledged by member counterparties and securities received or pledged as a result of the initial margin requirements imposed upon the Bank and its bilateral counterparties. The amount of non-cash collateral for uncleared derivatives included in the determination of the net amount is limited to the amount needed to secure the Bank's or the counterparties' uncleared exposure. At June 30, 2026 and December 31, 2025, the Bank had pledged excess non-cash collateral with fair values of $119,421,000 and $171,809,000, respectively, and the Bank had received excess non-cash collateral with fair values of $86,709,000 and $138,604,000, respectively, from its bilateral counterparties.
[4] Consists of securities pledged by the Bank. In addition to the amount needed to secure the counterparties' exposure to the Bank, the Bank had pledged securities with aggregate fair values of $168,374,000 and $303,499,000 at June 30, 2026 and December 31, 2025, respectively, to further secure its cleared derivatives, which is a result of the initial margin requirements imposed upon the Bank.
