The following table presents information about our investment portfolio, showing the gross unrealized gains and losses within each segment of the portfolio.

Unrealized losses on securities shown in the previous tables have not been recognized into income because management has the intent and ability to hold these securities for the foreseeable future. The decline in market value is due to changes in interest rates for debt securities and considered normal market fluctuations for equity securities. Management has also reviewed the issuers’ bond ratings, noting they are of high credit quality.

Trading account securities are marked to market with the change in value reported on the income statement. Gains and losses on available for sale securities are recognized if the security is either deemed to be other than temporarily impaired, or the security is sold. The following table shows gross gains and losses on investment securities for the three months ended March 31 of 2012 and 2011.
