Investment securities with an aggregate fair value of $56.8 million have had continuous unrealized losses for more than 12 months as of December 31, 2013, with an aggregate unrealized loss of $1.1 million. These 18 investments included mortgage-backed and government agency securities. None of the unrealized losses identified as of December 31, 2013, or December 31, 2012, relate to the marketability of the securities or the issuer’s ability to honor redemption obligations. For all periods presented, BancShares had the ability and intent to retain these securities for a period of time sufficient to recover all unrealized losses. Therefore, none of the securities were deemed to be other than temporarily impaired. Investment securities having an aggregate carrying value of $2.75 billion at December 31, 2013, and $2.35 billion at December 31, 2012, were pledged as collateral to secure public funds on deposit and certain short-term borrowings, and for other purposes as required by law.
