[1] Represents changes in the fair values of derivatives in cash flow hedging programs, primarily from open contracts in the hedging
of rolling issuance of CO discount notes, and any open contracts in cash flow hedges of anticipatory issuance of CO bonds. Also
includes unamortized gains and losses related to closed cash flow hedges that will be amortized in future periods from AOCI to
Interest expense. For more information, see table “Cash flow hedge gains and losses” in Note 17. Derivatives and Hedging
Activities.
[2] Represents cumulative hedge valuation basis adjustments on fair value hedges of AFS securities under the partial-term hedging
provisions of ASC 815. Amounts represent change in the benchmark rate of the hedged securities. Changes in the benchmark rate
on ASC 815 qualifying fair value hedges are recorded through earnings with an offset to the carrying values of the hedged AFS
securities. Changes in marked-to-market values of AFS securities are recorded to adjust the amortized cost of AFS securities with
an offset in AOCI. In AOCI, the marked-to-market gains and losses are reported separately from ASC 815 valuation changes due
to changes in the benchmark rate.
