Regulatory Restrictions and Capital Adequacy | Regulatory Restrictions and Capital Adequacy The amount of funds available to the parent from its subsidiary bank is limited by restrictions imposed on all depository institutions by banking regulation that restricts and limits the payment of dividends and the ability of depository institutions to engage in transactions, including lending transactions and asset purchases, with affiliates. First Commonwealth and First Commonwealth Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators which, if undertaken, could have a direct material effect on First Commonwealth’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, First Commonwealth and First Commonwealth Bank must meet specific capital guidelines that involve quantitative measures of First Commonwealth’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. First Commonwealth’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Effective January 1, 2015, First Commonwealth became subject to regulatory risk-based capital rules adopted by the federal banking agencies implementing Basel III. The capital rules require First Commonwealth to maintain the following minimum capital levels: •a minimum Tier I capital to risk-weighted assets of at least 6.0%, plus a capital conservation buffer of 2.5%, resulting in a required minimum ratio of 8.5% •a minimum Common Equity Tier 1 to risk weighted assets of at lest 4.5%, plus the capital conservation buffer of 2.5%, resulting in a required minimum ratio of 7%. •a minimum Total Capital to risk weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum of 10.5% •a minimum Leverage ratio, which is Tier 1 capital to adjusted average assets, of 4.0% The capital conservation buffer may only include capital that qualifies as Common Equity Tier 1. The Basel III Rules also permit banking organizations with less than $15.0 billion in assets to retain, through a one-time election, the exclusion of accumulated other comprehensive income from regulatory capital. The Company elected to retain this treatment, which reduces the volatility of regulatory capital levels. During the second quarter of 2018, First Commonwealth Bank, the Company's banking subsidiary, issued $100 million in subordinated debt, which under regulatory rules qualifies as Tier II capital. This subordinated debt issuance increased the total risk-based capital ratio by 160 basis points. As of December 31, 2020 and 2019, First Commonwealth and First Commonwealth Bank met all capital adequacy requirements to which they are subject and were considered well-capitalized under the regulatory rules as set forth in the tables below:
