Regulatory Capital

Regulatory Capital

Required Regulatory Capital

The Company is subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by the regulators, which could have a direct material impact on the financial statements. These requirements involve quantitative measures of assets, liabilities and certain off-balance sheet items calculated pursuant to regulatory guidance. The Company's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total, Tier 1 capital and common equity Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets, all as defined in the regulations.

At December 31, 2023 and 2022, the Company and Seacoast Bank, its wholly-owned banking subsidiary, were both considered “well capitalized” based on the applicable U.S. regulatory capital ratio requirements as reflected in the table below:
