The following table states the name of issuers, and the aggregate amortized cost and fair value of the securities of such issuer (includes available-for-sale and held-to-maturity securities), in which the aggregate amortized cost of such securities exceeds 10% of stockholders’ equity. This information excludes 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.
