During the fourth quarter of 2013, Trustmark reclassified approximately $1.099 billion of securities available for sale to securities held to maturity.  The securities were transferred at fair value, which became the cost basis for the securities held to maturity.  At the date of transfer, the net unrealized holding loss on the available for sale securities totaled approximately $46.6 million ($28.8 million, net of tax).  The net unrealized holding loss is amortized over the remaining life of the securities as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security.  There were no gains or losses recognized as a result of the transfer.  At March 31, 2014, the net unamortized, unrealized loss on the transferred securities included in accumulated other comprehensive loss in the accompanying balance sheet totaled approximately $45.0 million ($27.8 million, net of tax).

During the first quarter of 2014, Trustmark sold its remaining $25.9 million of Collateralized Loan Obligations (CLO) generating a net gain of $389 thousand. These securities were identified as available for sale and had been carried in the asset-backed securities and structured financial products line item in the table shown above.

The unrealized losses shown above are primarily due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality.  Because Trustmark does not intend to sell these securities and it is more likely than not that Trustmark will not be required to sell the investments before recovery of their amortized cost bases, which may be maturity, Trustmark does not consider these investments to be other-than-temporarily impaired at March 31, 2014.  There were no other-than-temporary impairments for the three months ended March 31, 2014 and 2013.

Security Gains and Losses

Gains and losses as a result of calls and dispositions of securities, as well as any associated proceeds, were as follows ($ in thousands):

Contractual Maturities

The amortized cost and estimated fair value of securities available for sale and held to maturity at March 31, 2014, by contractual maturity, are shown below ($ in thousands).  Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
