Minimum capital requirements

Note (12)—Minimum capital requirements:

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

For March 31, 2018 and December 31, 2017 Interim Final Basel III rules require the Bank to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets. Additionally under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. As of March 31, 2018 and December 31, 2017, the Bank and Company met all capital adequacy requirements to which it is subject. Also, as of March 31, 2018, the most recent notification from the Federal Deposit Insurance Corporation (“FDIC”), the Bank was well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.

The table below includes new regulatory capital ratio requirements that became effective on January 1, 2015. Beginning in 2016, an additional conservation buffer was added to the minimum requirements for capital adequacy purposes, subject to a three year phase-in period. As of March 31, 2018 and December 31, 2017, the buffer was 1.88% and 1.25%, respectively. The capital conservative buffer will be fully phased in January 1, 2019 at 2.5 percent.

Actual and required capital amounts and ratios are presented below at period-end:
