Regulatory Matters [Abstract] |
Regulatory Matters | 21. Regulatory Matters CTBI’s principal source of funds is dividends received from our banking subsidiary, CTB. Regulations limit the amount of dividends that may be paid by CTB without prior approval. During 2018, approximately $56.1 million plus any 2018 net profits can be paid by CTB without prior regulatory approval. The Federal Reserve Bank adopted quantitative measures which assign risk weightings to assets and off-balance sheet items and also define and set minimum regulatory capital requirements (risk based capital ratios). All banks are required to have a minimum Tier 1 (core capital) leverage ratio of 4% of adjusted quarterly average assets, common equity Tier 1 capital ratio of at least 4.5% of risk-weighted assets, Tier 1 capital of at least 6% of risk-weighted assets, and total capital of at least 8% of risk-weighted assets. Tier 1 capital consists principally of shareholders’ equity including capital-qualifying subordinated debt but excluding unrealized gains and losses on securities available-for-sale, less goodwill and certain other intangibles. Total capital consists of Tier 1 capital plus certain debt instruments and the reserve for credit losses, subject to limitation. Failure to meet certain capital requirements can initiate certain actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial statements. The regulations also define well-capitalized levels of Tier 1 leverage, common equity Tier 1 capital, Tier 1, and total capital as 5%, 6.5%, 8%, and 10%, respectively. We had Tier 1 leverage, common equity Tier 1 capital, Tier 1, and total capital ratios above the well-capitalized levels at December 31, 2017 and 2016. We believe, as of December 31, 2017, CTBI meets all capital adequacy requirements for which it is subject to be defined as well-capitalized under the regulatory framework for prompt corrective action. Under the current Federal Reserve Board’s regulatory framework, certain capital securities offered by wholly owned unconsolidated trust preferred entities of CTBI are included as Tier 1 regulatory capital. On March 1, 2005, the Federal Reserve Board adopted a final rule that allows the continued limited inclusion of trust preferred securities in the Tier 1 capital of bank holding companies (“BHCs”). Under the final rule, trust preferred securities and other restricted core capital elements are subject to stricter quantitative limits. The Board’s final rule limits restricted core capital elements to 25 percent of all core capital elements, net of goodwill less any associated deferred tax liability. Amounts of restricted core capital elements in excess of these limits generally may be included in Tier 2 capital. The final rule provided a five-year transition period, which ended March 31, 2009, for application of the quantitative limits. The requirement for trust preferred securities to include a call option has been eliminated, and standards for the junior subordinated debt underlying trust preferred securities eligible for Tier 1 capital treatment have been clarified. The final rule addresses supervisory concerns, competitive equity considerations, and the accounting for trust preferred securities. The final rule also strengthens the definition of regulatory capital by incorporating longstanding Board policies regarding the acceptable terms of capital instruments included in banking organizations’ Tier 1 or Tier 2 capital. The final rule did not have a material impact on our regulatory ratios. Consolidated Capital Ratios

On July 2, 2013, the Federal Reserve approved final rules that substantially amend the regulatory risk-based capital rules applicable to CTBI and CTB. The FDIC subsequently approved these rules. The final rules implement the “Basel III” regulatory capital reforms and changes required by the Dodd-Frank Act. The rules include new risk-based capital and leverage ratios, which are being phased in from 2015 to 2019, and refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to CTBI and CTB under the final rules are: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The final rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital. The capital conservation buffer began to be phased in on January 1, 2016 at 0.625% of risk-weighted assets and will increase by 0.625% annually until fully implemented in January 2019. An institution is subject to limitations on certain activities including payment of dividends, share repurchases, and discretionary bonuses to executive officers if its capital level is below the total capital plus capital conservation buffer amount. The final rules also implement revisions and clarifications consistent with Basel III regarding the various components of Tier 1 capital, including common equity, unrealized gains and losses (which are not considered a component of Tier 1 capital), as well as certain instruments that will no longer qualify as Tier 1 capital, some of which will be phased out over time. However, the final rules provide that small depository institution holding companies with less than $15 billion in total assets as of December 31, 2009 (which includes CTBI) will be able to permanently include non-qualifying instruments that were issued and included in Tier 1 or Tier 2 capital prior to May 19, 2010 in additional Tier 1 or Tier 2 capital until they redeem such instruments or until the instruments mature. The final rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions, including CTB, if their capital levels begin to show signs of weakness. These revisions took effect January 1, 2015. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 5% (unchanged from previous rules). The final rules set forth certain changes for the calculation of risk-weighted assets, which we were required to utilize beginning January 1, 2015. The standardized approach final rule utilizes an increased number of credit risk exposure categories and risk weights, and also addresses: (i) an alternative standard of creditworthiness consistent with Section 939A of the Dodd-Frank Act; (ii) revisions to recognition of credit risk mitigation; (iii) rules for risk weighting of equity exposures and past due loans; (iv) revised capital treatment for derivatives and repo-style transactions; and (v) disclosure requirements for top-tier banking organizations with $50 billion or more in total assets that are not subject to the “advance approach rules” that apply to banks with greater than $250 billion in consolidated assets. We currently satisfy the well-capitalized and the capital conservation standards, and based on our current capital composition and levels, we anticipate that our capital ratios, on a Basel III basis, will continue to exceed the well-capitalized minimum capital requirements and capital conservation buffer standards.
