[1]	Includes $18.2 billion pledged to secure government and trust deposits, assets sold under agreements to repurchase, credit facilities and loan servicing agreements that the secured parties are not permitted to sell or repledge the collateral, of which $16.9 billion serve as collateral for public funds.

The weighted average yield on debt securities available-for-sale is based on amortized cost; therefore, it does not give effect to changes in fair value.

Securities not due on a single contractual maturity date, such as mortgage-backed securities and collateralized mortgage obligations, are classified in the period of final contractual maturity. The expected maturities of collateralized mortgage obligations, mortgage-backed securities and certain other securities may differ from their contractual maturities because they may be subject to prepayments or may be called by the issuer.

The following table presents the aggregate amortized cost and fair value of debt securities available-for-sale at December 31, 2021 by contractual maturity.

As of December 31, 2021, the portfolio of available-for-sale debt securities reflects gross unrealized losses of approximately $298 million, driven mainly by U.S. Treasury Securities and mortgage-backed securities, which were impacted by increases in the interest rate environment.

The following table states the name of issuers, and the aggregate amortized cost and fair value of the debt securities of such issuer (includes available-for-sale and held-to-maturity debt securities), in which the aggregate amortized cost of such securities exceeds 10% of stockholders’ equity. This information excludes debt securities backed by the full faith and credit of the U.S. Government. Investments in obligations issued by a state of the U.S. and its political subdivisions and agencies, which are payable and secured by the same source of revenue or taxing authority, other than the U.S. Government, are considered securities of a single issuer.
