The gross unrealized losses areattributed to overall wider credit spreads for state and municipal securities, wider credit spreads for specific issuers, adverse changes in market benchmark interest rates, or a combination thereof, all as compared to those prevailing when the investment securities were acquired.

Overall, for the investment securities in gross unrealized loss positions identified above, (i) the Company does not intend to sell the investment securities, (ii) it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and (iii) the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairment during thesix months endedJune 30, 2013 or the year ended December 31, 2012.
