Upon acquisition of a security, the Bank determines the appropriate impairment model that is applicable. If the security is a beneficial interest in securitized financial assets, the Bank uses the beneficial interests in securitized financial assets impairment model. If the security is not a beneficial interest in securitized financial assets, the Bank uses the debt and equity securities impairment model. The Bank conducts periodic reviews to evaluate each security to determine whether an other-than-temporary impairment has occurred. The Bank does not have any securities that have been classified as other-than-temporarily-impaired at September 30, 2013 or December 31, 2012.

At September 30, 2013 and December 31, 2012, the significant categories of temporarily impaired securities and management’s evaluation of those securities are as follows:

State and municipal securities: At September 30, 2013, three investments in obligations of state and municipal securities had unrealized losses. The Bank believes the unrealized losses on those investments were caused by the interest rate environment and does not relate to the underlying credit quality of the issuers. Because the Bank has the intent and ability to hold those investments for a time necessary to recover their amortized cost bases, which may be until maturity, the Bank does not consider those investments to be other-than-temporarily impaired at September 30, 2013.

Mortgage-backed securities: At September 30, 2013, eighteen investments in residential mortgage-backed securities had unrealized losses. This impairment is believed to be caused by the current interest rate environment. The contractual cash flows of those investments are guaranteed or issued by an agency of the U.S. Government. Because the decline in market value is attributable to the current interest rate environment and not credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not deem those investments to be other-than-temporarily impaired at September 30, 2013.
