Regulatory Capital Requirements [Abstract] |
Summary of Regulatory Capital Requirement | The final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective for Pinnacle Financial on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The minimum capital level requirements applicable to bank holding companies and banks subject to the rules are: (i) a common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6%; (iii) a total capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4% for all institutions. The Basel III rules, also establish a capital conservation buffer of 2.5% (to be phased in over three years) above the regulatory minimum risk-based capital ratios. The phase-in of the capital conservation buffer requirement commenced in January 2016 at 0.625% of risk-weighted assets and increases each year by a like percentage until fully implemented in January 2019. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital. Management believes, as of December 31, 2018, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Financial and Pinnacle Bank must maintain certain total, Tier 1, common equity Tier 1 and Tier 1 leverage capital ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level. The capital conservation buffer is not included in the required ratios of the table presented below. Pinnacle Financial's and Pinnacle Bank's actual capital amounts and ratios are presented in the following table (in thousands):
