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 debt securities at December 31, 2018 are summarized as follows:

In 2018, we had a net securities loss of $0.1 million. There was a net loss of $1.3 million realized on sales and calls of AFS securities, consisting of a pre-tax gain of $0.3 million and a pre-tax loss of $1.6 million. This net loss included a loss of $0.4 million from the sale of CTBI’s CRA investment funds in the first quarter of 2018. Also included in securities gains and losses for 2018 was an unrealized gain of $1.2 million from equity securities, discussed below, in the fourth quarter of 2018. There was a net gain of $0.1 million realized in 2017 and a net gain of $0.5 million realized in 2016.

Equity Securities at Fair Value

In 2008, Visa distributed 9,918 shares of Visa Class B restricted stock to CTBI which, upon resolution of certain pending legal matters, will become unrestricted and convertible into Visa Class A shares. Following this distribution, significant concern existed about the ultimate realizable value of these shares, and because CTBI did not have a basis in the stock, the shares were previously not recorded as an asset on CTBI’s balance sheet. In recent years, the concern over the realizable value has stabilized, and in late 2017 and 2018, several sales of Visa Class B shares have occurred. While not traded in observable markets, these sales were reported by several financial institutions in various SEC 8-K and 10-K filings. In 2018, FASB issued a technical correction to its guidance regarding equity securities, ASC 321-10-35-2, allowing an entity to subsequently elect to record an equity security without a readily determinable fair value. In 2018, CTBI made the election permitted by ASC 321-10-35-2 to record its Visa Class B shares at fair value. On December 31, 2018, CTBI recorded a $1.2 million gain on the recognition of the fair value of 9,918 Visa Class B shares held in its portfolio.

The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $258.8 million at December 31, 2018 and $225.7 million at December 31, 2017.

The amortized cost of securities sold under agreements to repurchase amounted to $289.1 million at December 31, 2018 and $296.4 million at December 31, 2017.

CTBI evaluates its investment portfolio on a quarterly basis for impairment. The analysis performed as of December 31, 2018 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 December 31, 2018 was 75.7% compared to 69.5% as of December 31, 2017. 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, 2018 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, 2018.

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 December 31, 2018, 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 December 31, 2018, 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 December 31, 2018, 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.

Other Debt Securities

The unrealized losses in other debt securities 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 December 31, 2018, 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.

CRA Investment Funds

In 2017, CTBI’s CRA investment funds consisted 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 December 31, 2017.
