When securities are sold, the adjusted cost of the specific security sold is used to compute the gain or loss on the sale.
 
The actual maturities of certain securities may differ from the contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. A schedule of the contractual maturities of securities available for sale and securities held to maturity as of June 30, 2019 is presented below:
 
Due in one year or less
 
Due after one year to five years
 
Due after five to ten years
 
Due after ten years

Inclusive in the table above is $18.1 million of callable securities at June 30, 2019.
The carrying value of securities pledged to secure public funds, trust deposits, and for other purposes, as required or permitted by law, was $355.0 million and $361.1 million at June 30, 2019 and December 31, 2018, respectively.
At June 30, 2019 and December 31, 2018, the Company had no investments in obligations of individual states, counties, or municipalities which exceeded 10% of stockholders’ equity.
Other-Than-Temporary Impairment ("OTTI")
The Company continually reviews investment securities for the existence of OTTI, taking into consideration current market conditions, the extent and nature of changes in fair value, issuer rating changes and trends, the credit worthiness of the obligor of the security, volatility of earnings, current analysts’ evaluations, the Company’s intent to sell the security, whether it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery, as well as other qualitative factors. The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment.
The following tables show the gross unrealized losses and fair value of the Company’s investments in an unrealized loss position, which the Company has not deemed to be OTTI, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis. As a result, the Company does not consider these investments to be OTTI and accordingly, there was no OTTI recorded for the six months ended June 30, 2019 and 2018. There was no cumulative credit related component of OTTI as of June 30, 2019 or December 31, 2018. The Company made this determination by reviewing various qualitative and quantitative factors regarding each investment category, such as current market conditions, extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, and current analysts’ evaluations.
As a result of the Company’s review of these qualitative and quantitative factors, the causes of the impairments listed in the table above by category are as follows at June 30, 2019:
•
U.S. Government Agency Securities, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities: These portfolios have contractual terms that generally do not permit the issuer to settle the securities at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality. Additionally, these securities are implicitly guaranteed by the U.S. Government or one of its agencies.
•
Single Issuer Trust Preferred Securities: This portfolio consists of two securities, which are investment grade. The unrealized loss on these securities is attributable to the illiquid nature of the trust preferred market in the current economic environment. Management evaluates various financial metrics for the issuers, including regulatory capital ratios of the issuers.
•
Pooled Trust Preferred Securities: This portfolio consists of one below investment grade security which is performing. The unrealized loss on this security is attributable to the illiquid nature of the trust preferred market in the current economic and regulatory environment. Management evaluates collateral credit and instrument structure, including current and expected deferral and default rates and timing. In addition, discount rates are determined by evaluating comparable spreads observed currently in the market for similar instruments.
