SECURITIES

Trading Securities

During 2012 the Company transferred equity securities classified previously as trading to available for sale. The majority of these securities are held solely for the purpose of funding certain executive nonqualified retirement obligations (see Note 15 “Employee Benefit Plans”). The remainder of the portfolio is comprised of equity securities, which consists of a fund whose investment objective is to invest in geographically specific private placement debt securities designed to support underlying economic activities such as community development and affordable housing. The Company realized a gain on trading activities of $285,000 in 2012, which was included in other income.

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 December 31, 2014 is presented below:

Inclusive in the table above is $34.8 million of callable securities at December 31, 2014.

The carrying value of securities pledged to secure public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law, was $340.0 million and $360.1 million at December 31, 2014 and 2013, respectively.

At December 31, 2014 and 2013, the Company had no investments in obligations of individual states, counties, or municipalities, which exceeded 10% of stockholders’ equity.

Other-Than-Temporary Impairment

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, or 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 is 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 the security before the recovery of its amortized cost basis. As a result, the Company does not consider these investments to be OTTI. 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 December 31, 2014:

•

U.S. Government Agency Securities, Agency Mortgage-Backed Securities and Collateralized Mortgage Obligations: This portfolio has 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, one of which is below 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 each of the issuers, including regulatory capital ratios of the issuers.

•

Pooled Trust Preferred Securities: This portfolio consists of two below investment grade securities both of which are performing. The unrealized loss on these securities is attributable to the illiquid nature of the trust preferred market and the significant risk premiums required in the current economic 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.

•

Equity Securities: This portfolio consists of mutual funds and other equity investments. During some periods, the mutual funds in the Company’s investment portfolio may have unrealized losses resulting from market fluctuations as well as the risk premium associated with that particular asset class. For example, emerging market equities tend to trade at a higher risk premium than U.S. government bonds and thus, will fluctuate to a greater degree on both the upside and the downside. In the context of a well-diversified portfolio, however, the correlation amongst the various asset classes represented by the funds serves to minimize downside risk. The Company evaluates each mutual fund in the portfolio regularly and measures performance on both an absolute and relative basis. A reasonable recovery period for positions with an unrealized loss is based on management’s assessment of general economic data, trends within a particular asset class, valuations, earnings forecasts and bond durations.

The following table shows the total OTTI that the Company recorded for the periods indicated:
