As of March 31, 2018 and December 31, 2017, the Company's investment securities portfolio contained unrealized losses on agency securities issued or backed by the full faith and credit of the United States government or are generally viewed as having the implied guarantee of the U.S. government, U.S treasury securities, obligations of states and political subdivisions and mortgage backed securities issued by government sponsored entities. For fixed maturity investments management considers whether the present value of cash flows expected to be collected are less than the security's amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company's intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more likely than not that it will not be required to sell the security before recovery of the security's amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. The Company has concluded that any impairment of its investment securities portfolio outlined in the above table is not other than temporary and is the result of interest rate changes, sector credit rating changes, or issuer-specific rating changes that are not expected to result in the non-collection of principal and interest during the period.
