OTTI losses on impaired securities must be fully recognized in earnings if an investor has the intent to sell the debt security or if it is more likely than not that the investor will be required to sell the debt security before recovery of its amortized cost. However, even if an investor does not expect to sell a debt security in an unrealized loss position, the investor must evaluate the expected cash flows to be received and determine if a credit loss has occurred. In the event that a credit loss has occurred, only the amount of impairment associated with the credit loss is recognized in earnings in the Consolidated Statements of Income. Amounts relating to factors other than credit losses are recorded in accumulated other comprehensive loss (“AOCL”) within Stockholders’ Equity. Unrealized losses on available for sale securities, that are deemed to be temporary, are recorded in AOCL, net of tax.
 
The Company reviewed each investment that had an unrealized loss at
March
31,
2017
and
December
31,
2016.
The unrealized losses in securities held-to-maturity at
March
31,
2017
and
December
31,
2016
were caused by illiquidity in the market and movements in interest rates.
 
The unrealized losses in securities available for sale at
March
31,
2017
and
December
31,
2016
were caused by movements in interest rates. It is not anticipated that these securities would be settled at a price that is less than the amortized cost of the Company’s investment. Each of these securities is performing according to its terms and, in the opinion of management, will continue to perform according to its terms. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities’ amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities. Therefore, the Company did
not
consider these investments to be other-than-temporarily impaired at
March
31,
2017
and
December
31,
2016.
 
The Company did
not
sell any securities during the
three
months ended
March
31,
2017
and
2016.
