Upon acquisition of a security, Cornerstone determines the appropriate impairment model that is applicable. If the security is a beneficial interest in securitized financial assets, Cornerstone uses the beneficial interests in securitized financial assets impairment model. If the security is not a beneficial interest in securitized financial assets, Cornerstone uses the debt and equity securities impairment model. Cornerstone conducts periodic reviews to evaluate each security to determine whether an other-than-temporary impairment has occurred. Cornerstone does not have any securities that have been classified as other-than-temporarily impaired at December 31, 2014.
 
At December 31, 2014, the significant categories of temporarily impaired securities, and management’s evaluation of those securities are as follows:
 
Mortgage-backed securities: At December 31, 2014, twelve 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 Cornerstone does not intend to sell the investments and it is not more likely than not that Cornerstone will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, Cornerstone does not deem those investments to be other-than-temporarily impaired at December 31, 2014.
