Securities [Abstract] |
Securities | 3. Securities Debt securities are classified into HTM and AFS categories. HTM securities are those that CTBI has the positive intent and ability to hold to maturity and are reported at amortized cost. AFS securities are those that CTBI may decide to sell if needed for liquidity, asset-liability management, or other reasons. AFS securities are reported at fair value, with unrealized gains or losses included as a separate component of equity, net of tax. As of December 31, 2022 and December 31, 2021, CTBI had no HTM securities. The amortized cost and fair value of debt securities at December 31, 2022 are summarized as follows: Available-for-Sale

In 2022, we had a net securities loss of $168 thousand. There was a net loss of $81 thousand realized on sales and calls of AFS securities, and an unrealized loss of $87 thousand from the fair value adjustment of equity securities. There was a net loss of $158 thousand realized in 2021 and a net gain of $1.8 million realized in 2020. Equity Securities at Fair Value CTBI made the election permitted by ASC 321-10-35-2 to record its Visa Class B shares at fair value. Equity securities at fair value as of December 31, 2022 were $2.2 million, as a result of an $87 thousand decrease in the fair value in 2022. The fair value of equity securities decreased $218 thousand in 2021. No equity securities were sold during 2022 or 2021. The amortized cost of securities pledged as collateral, to secure public deposits and for other purposes, was $725.0 million at December 31, 2022 and $545.6 million at December 31, 2021. The amortized cost of securities sold under agreements to repurchase amounted to $316.9 million at December 31, 2022 and $314.1 million at December 31, 2021. CTBI evaluates its investment portfolio on a quarterly basis for impairment. The analysis performed as of December 31, 2022 indicates that all impairment is considered temporary, market and interest rate driven, and not credit-related. The percentage of total debt securities with unrealized losses as of December 31, 2022 was 97.4% compared to 72.4% as of December 31, 2021. The following table provides the amortized cost, gross unrealized losses, and fair value, aggregated by investment category and length of time the individual securities have been in a continuous unrealized loss position as of December 31, 2022 that are not deemed to have credit losses. As stated above, CTBI had no HTM securities as of December 31, 2022. Available-for-Sale

U.S. Treasury and Government Agencies The unrealized losses in U.S. Treasury and government agencies were caused by interest rate changes. 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 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. State and Political Subdivisions The unrealized losses in securities of state and political subdivisions were caused by interest rate changes. 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 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. 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 changes. CTBI expects to recover the amortized cost basis over the term of the securities. 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. Asset-Backed Securities The unrealized losses in asset-backed securities were caused by interest rate changes. 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 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.
