There were no securities classified as trading at December 31, 2016 or 2015.

Unrealized losses on investment securities result from the cost basis of the security being higher than its current fair value. These differences generally occur because of changes in interest rates since the time of purchase, or because the credit quality of the issuer has deteriorated. We perform a quarterly analysis of each security in our portfolio to determine if impairment exists, and if it does, whether that impairment is other-than-temporary.

At December 31, 2016, all of our MBSs and CMOs held were issued by U.S. government-sponsored entities and agencies, primarily the Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”), institutions which the government has affirmed its commitment to support. As the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and we do not intend to sell these securities and it is not likely that we will be required to sell the securities before their anticipated recovery, we do not consider these securities to be other-than-temporarily impaired at December 31, 2016.

Agency MBSs and Agency CMOs consist of pools of residential mortgages which are guaranteed by FNMA, FHLMC, or Government National Mortgage Association (“GNMA”) with various origination dates and maturities. Agency CMBS consists of bonds backed by commercial real estate which are guaranteed by FNMA and GNMA.

During 2014 and 2013, securities were transferred from available for sale to held to maturity. The amortization of the unamortized net holding loss reported in accumulated other comprehensive income offsets the effect on interest income of the discount for the transferred securities. The remaining unamortized balance of the net losses for the securities transferred from available for sale to held to maturity was $2.17 million or $1.41 million, net of tax at December 31, 2016.
