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
September 30, 2017
and
December 31, 2016.
The unrealized losses in municipal securities held-to-maturity at
September 30, 2017
and
December 31, 2016
were caused by illiquidity in the market and movements in interest rates. The unrealized losses in FNMA securities held-to-maturity at
September 30, 2017
were caused by movements in interest rates. The unrealized losses in securities available for sale at
September 30, 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
September 30, 2017
and
December 31, 2016.
 
Realized gains and losses on the sales of securities are determined using the specific identification method. The Company sold available for sale securities totaling
$112.4
million during the
three
months ended
September 30, 2017.
The Company did
not
sell any available for sale securities during the
three
months ended
September 30, 2016.
The Company sold available for sale securities totaling
$112.4
million and
$64.6
million during the
nine
months ended
September 30, 2017
and
2016,
respectively.
