Note 3 – Securities

Securities are classified into held-to-maturity and available-for-sale categories. Held-to-maturity (HTM) securities are those that CTBI has the positive intent and ability to hold to maturity and are reported at amortized cost. Available-for-sale (AFS) securities are those that CTBI may decide to sell if needed for liquidity, asset-liability management or other reasons. Available-for-sale securities are reported at fair value, with unrealized gains or losses included as a separate component of equity, net of tax.

The amortized cost and fair value of securities at March 31, 2017 are summarized as follows:

As of March 31, 2017, there was a loss of $8 thousand realized on the call of an AFS security. As of March 31, 2016, there was a net gain of $68 thousand on sales.

The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $222.0 million at March 31, 2017 and $221.2 million at December 31, 2016.

The amortized cost of securities sold under agreements to repurchase amounted to $304.7 million at March 31, 2017 and $303.5 million at December 31, 2016.

CTBI evaluates its investment portfolio on a quarterly basis for impairment. The analysis performed as of March 31, 2017 indicates that all impairment is considered temporary, market and interest rate driven, and not credit-related. The percentage of total investments with unrealized losses as of March 31, 2017 was 62.6% compared to 65.6% as of December 31, 2016. The following tables provide the amortized cost, gross unrealized losses, and fair market value, aggregated by investment category and length of time the individual securities have been in a continuous unrealized loss position as of March 31, 2017 that are not deemed to be other-than-temporarily impaired. There were no held-to-maturity securities that were deemed to be impaired as of March 31, 2017.

U.S. Treasury and Government Agencies

The unrealized losses in U.S. Treasury and government agencies were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than par which will equal amortized cost at maturity. CTBI does not consider those investments to be other-than-temporarily impaired at March 31, 2017, because CTBI does not intend to sell the investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost, which may be maturity.

State and Political Subdivisions

The unrealized losses in securities of state and political subdivisions were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than par which will equal amortized cost at maturity. CTBI does not consider those investments to be other-than-temporarily impaired at March 31, 2017, because CTBI does not intend to sell the investments before recovery of their amortized cost and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost, which may be maturity.

U.S. Government Sponsored Agency Mortgage-Backed Securities

The unrealized losses in U.S. government sponsored agency mortgage-backed securities were caused by interest rate increases. CTBI expects to recover the amortized cost basis over the term of the securities. CTBI does not consider those investments to be other-than-temporarily impaired at March 31, 2017, because (i) the decline in market value is attributable to changes in interest rates and not credit quality, (ii) CTBI does not intend to sell the investments, and (iii) it is not more likely than not we will be required to sell the investments before recovery of their amortized cost, which may be maturity.

CRA Investment Funds

CTBI’s CRA investment funds consist of investments in fixed income mutual funds ($24.4 million of the total fair value and $718 thousand of the total unrealized losses in common stock investments). The severity of the impairment (fair value is approximately 2.9% less than cost) and the duration of the impairment correlates with the decline in long-term interest rates in 2017. CTBI evaluated the near-term prospects of these funds in relation to the severity and duration of the impairment. Based on that evaluation, CTBI does not consider those investments to be other-than-temporarily impaired at March 31, 2017.

The analysis performed as of December 31, 2016 indicated that all impairment was considered temporary, market and interest rate driven, and not credit-related. The following tables provide the amortized cost, gross unrealized losses, and fair market value, aggregated by investment category and length of time the individual securities have been in a continuous unrealized loss position as of December 31, 2016 that are not deemed to be other-than-temporarily impaired. There were no held-to-maturity securities that were deemed to be impaired as of December 31, 2016.
