Regulatory Capital Requirements under Banking Regulations [Abstract] |
Regulatory Capital | Regulatory Capital Horizon and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies and are assigned to a capital category. Failure to meet the minimum regulatory capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators, which if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective actions, the Company and Bank must meet specific capital guidelines involving quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and Bank’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 and the Bank to maintain minimum amounts and ratios of total and Tier I capital to risk-weighted assets, and of Tier I capital to average assets, or leverage ratio. For December 31, 2023 and 2022, Basel III rules require the Company and 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. To be categorized as well capitalized, the Company and Bank must maintain minimum Total risk-based, Tier I risk-based, common equity Tier I risk-based and Tier I leverage ratios as set forth in the table below. As of December 31, 2023 and December 31, 2022, the Bank met all capital adequacy requirements to be considered well capitalized. There have been no conditions or events since the year ending December 31, 2023 that management believes have changed the Bank’s classification as well capitalized. There is no threshold for well-capitalized status for bank holding companies. Horizon and the Bank’s actual and required capital ratios as of December 31, 2023 and 2022 were as follows:
| Actual |  | Required for Capital Adequacy Purposes(1) |  | Required For Capital Adequacy Purposes with Capital Buffer(1) |  | Well Capitalized Under Prompt Corrective Action Provisions(1)
| Amount |  | Ratio |  | Amount |  | Ratio |  | Amount |  | Ratio |  | Amount |  | Ratio
