(a)Yield is calculated using the effective yield of each security at the end of the period, weighted based on the market value by security for the securities within each maturity distribution range.

Yield does not consider hedging effects for securities in active hedges. (b)Fair value includes basis adjustments for securities in closed portfolios with active hedges under the portfolio layer method. This includes a $4 million asset and a $72 million liability for agency mortgage-backed residential securities at March 31, 2025, and December 31, 2024, respectively, and a $7 million asset and a $34 million liability for agency mortgage-backed commercial securities at March 31, 2025, and December 31, 2024. These basis adjustments would be allocated to the amortized cost of specific securities within the pool if the hedge was dedesignated. Refer to Note 19 for additional information. (c)Yield is calculated using the effective yield of each security at the end of the period, weighted based on amortized cost by security for the securities within each maturity distribution range. The effective yield considers the contractual coupon and amortized cost and excludes capital gains, capital losses, and the premium or discount on securities transferred from available-for-sale to held-to-maturity.
