⁽¹⁾	Unrealized gains/(losses) related to available-for-sale securities are reported in accumulated other comprehensive income.

⁽²⁾	Held-to-maturity securities are carried in the consolidated statements of financial condition at amortized cost, and the changes in the value of these securities, other than impairment charges, are not reported on the consolidated financial statements.

For the three months ended March 31, 2013, we received proceeds of $18.2 million from the sale of available-for-sale securities, which resulted in realized gains of $1.0 million. For the three months ended March 31, 2012, we received proceeds of $2.7 million from the sale of available-for-sale securities, which resulted in an immaterial amount of realized gains.

During the three months ended March 31, 2013, unrealized losses, net of deferred tax benefits, of $4.6 million were recorded in accumulated other comprehensive income in the consolidated statements of financial condition. During the three months ended March 31, 2012, unrealized gains, net of deferred taxes, of $4.9 million were recorded in accumulated other comprehensive income in the consolidated statements of financial condition.

The table below summarizes the amortized cost and fair values of debt securities, by contractual maturity (in thousands). Expected maturities may differ significantly from contractual maturities, as issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

At March 31, 2013 and December 31, 2012, securities of $563.1 million and $613.8 million, respectively, were pledged at the Federal Home Loan Bank as collateral for borrowings and letters of credit obtained to secure public deposits.

The gross unrealized losses on our available-for-sale securities of $5.9 million as of March 31, 2013 relate to 58 individual securities.

Certain investments in the available-for-sale portfolio at March 31, 2013, are reported in the consolidated statements of financial condition at an amount less than their amortized cost. The total fair value of these investments at March 31, 2013, was $623.1 million, which was 36.0% of our available-for-sale investment portfolio. The amortized cost basis of these investments was $629.0 million at March 31, 2013. As discussed in more detail below, we conduct periodic reviews of all securities with unrealized losses to assess whether the impairment is other-than-temporary.

Other-Than-Temporary Impairment

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment; recent events specific to the issuer and/or industry to which the issuer belongs; the payment structure of the security; external credit ratings and the failure of the issuer to make scheduled interest or principal payments; the value of underlying collateral; and current market conditions.

If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in earnings. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows. There were no credit-related OTTI charges during the three months ended March 31, 2013.

We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.

We believe the gross unrealized losses related to all other securities of $5.9 million as of March 31, 2013 are attributable to issuer specific credit spreads and changes in market interest rates and asset spreads. We therefore do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.
