• Securities Available-for-Sale

        The following tables present amortized cost, gross unrealized gains and losses and carrying value, which is the estimated fair value, of securities available-for-sale as of the dates indicated. The private label collateralized mortgage obligations were acquired in the FDIC-assisted acquisition of Affinity in August 2009 and are covered by a FDIC loss sharing agreement. Other securities primarily consist of equity securities and an investment in overnight money market funds at a financial institution. See Note 10, Fair Value Measurements, for information on fair value measurements and methodology.

        Mortgage-backed securities have contractual terms to maturity and require periodic payments to reduce principal. In addition, expected maturities may differ from contractual maturities because obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

        The following table presents the contractual maturity distribution of our available-for-sale securities portfolio based on amortized cost and carrying value as of the date indicated:

        At March 31, 2012, the estimated fair value of debt securities and residential mortgage-backed debt securities issued by the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation was approximately $1.1 billion.

        As of March 31, 2012, securities available-for-sale with an estimated fair value of $72.0 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements.

        The following tables present, for those securities that were in a gross unrealized loss position, the carrying values and the gross unrealized losses on securities by length of time the securities were in an unrealized loss position as of the dates indicated:

        We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at March 31, 2012, and concluded that their losses were a result of the level of market interest rates relative to the types of securities and not a result of the underlying issuers' abilities to repay. Accordingly, we determined that the securities were temporarily impaired. Additionally, we have no plans to sell these securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost. Therefore, we did not recognize the temporary impairment in the consolidated statements of earnings.

• FHLB Stock

        At March 31, 2012, the Company had a $43.9 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. In January 2009, the FHLB announced that it suspended excess FHLB stock redemptions and dividend payments. Since this announcement, the FHLB has declared and paid cash dividends in 2010, 2011and 2012, though at rates less than those paid in the past, and repurchased certain amounts of our excess stock at carrying value. We evaluated the carrying value of our FHLB stock investment at March 31, 2012, and determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, the actions being taken by the FHLB to address its regulatory situation, repurchase activity of excess stock by the FHLB, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.
