Regulatory Matters | Regulatory Matters (In Thousands) Renasant Bank is 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 that, if undertaken, could have a direct material effect on Renasant Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Renasant Bank must meet specific capital guidelines that involve quantitative measures of Renasant Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Renasant Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The Federal Reserve, the FDIC and the Office of the Comptroller of the Currency have issued guidelines governing the levels of capital that banks must maintain. Those guidelines specify capital tiers, which include the following classifications:
Capital Tiers | Tier 1 Capital to Average Assets (Leverage) |  | Common Equity Tier 1 to Risk - Weighted Assets |  | Tier 1 Capital to Risk – Weighted Assets |  | Total Capital to Risk – Weighted Assets
Well capitalized | 5% or above |  | 6.5% or above |  | 8% or above |  | 10% or above
Adequately capitalized | 4% or above |  | 4.5% or above |  | 6% or above |  | 8% or above
Undercapitalized | Less than 4% |  | Less than 4.5% |  | Less than 6% |  | Less than 8%
Significantly undercapitalized | Less than 3% |  | Less than 3% |  | Less than 4% |  | Less than 6%
Critically undercapitalized | Tangible Equity / Total Assets less than 2%
The following table provides the capital and risk-based capital and leverage ratios for the Company and for Renasant Bank as of the dates presented:

In July 2013, the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency approved the implementation of the Basel III regulatory capital reforms and issued rules effecting certain changes required by the Dodd-Frank Act (the “Basel III Rules”) that call for broad and comprehensive revision of regulatory capital standards for U.S. banking organizations. Generally, the new Basel III Rules became effective on January 1, 2015, although parts of the Basel III Rules will be phased in through 2019. The Basel III Rules implemented a new common equity Tier 1 minimum capital requirement (“CET1”), and a higher minimum Tier 1 capital requirement, as reflected in the table above, and adjusted other items affecting the calculation of the numerator of a banking organization’s risk-based capital ratios. The new CET1 capital ratio includes common equity as defined under GAAP and does not include any other type of non-common equity under GAAP. Additionally, the Basel III Rules apply limits to a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a specified amount of CET1 capital in addition to the amount necessary to meet its minimum risk-based capital requirements. Further, the Basel III Rules changed the agencies’ general risk-based capital requirements for determining risk-weighted assets, which affect the calculation of the denominator of a banking organization’s risk-based capital ratios. The Basel III Rules have revised the agencies’ rules for calculating risk-weighted assets to enhance risk sensitivity and to incorporate certain international capital standards of the Basel Committee on Banking Supervision set forth in the standardized approach of the “International Convergence of Capital Measurement and Capital Standards: A Revised Framework”. The calculation of risk-weighted assets in the denominator of the Basel III capital ratios has been adjusted to reflect the higher risk nature of certain types of loans. Specifically, as applicable to the Company and Renasant Bank: — Residential mortgages: Replaced the former 50% risk weight for performing residential first-lien mortgages and a 100% risk-weight for all other mortgages with a risk weight of between 35% and 200% determined by the mortgage’s loan-to-value ratio and whether the mortgage falls into one of two categories based on eight criteria that include the term, use of negative amortization and balloon payments, certain rate increases and documented and verified borrower income. — Commercial mortgages: Replaced the former 100% risk weight with a 150% risk weight for certain high volatility commercial real estate acquisition, development and construction loans. — Nonperforming loans: Replaced the former 100% risk weight with a 150% risk weight for loans, other than residential mortgages, that are 90 days past due or on nonaccrual status. The Basel III Rules also introduce a new capital conservation buffer designed to absorb losses during periods of economic stress. The capital conservation buffer is composed entirely of CET1, on top of these minimum risk-weighted asset ratios. In addition, the Final Rules provide for a countercyclical capital buffer applicable only to certain covered institutions. It is not expected that the countercyclical capital buffer will be applicable to the Company or Renasant Bank. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a 4-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019).
