A System institution's regulatory capital ratios are as follows:(1)CET1 capital ratio. A System institution's CET1 capital ratio is the ratio of the System institution's CET1 capital to total risk-weighted assets;(2)Tier 1 capital ratio. A System institution's tier 1 capital ratio is the ratio of the System institution's tier 1 capital to total risk-weighted assets;(3)Total capital ratio. A System institution's total capital ratio is the ratio of the System institution's total (tier 1 and tier 2) capital to total risk-weighted assets; and(4)Tier 1 leverage ratio.(i) A System institution's leverage ratio is the ratio of the institution's tier 1 capital to the institution's average total consolidated assets as reported on the institution's Call Report net of deductions and adjustments from tier 1 capital under §§ 628.22(a), (b) , and (c) and 628.23.(ii) To calculate the measure of URE and URE equivalents described in paragraph (b)(4) of this section, a System institution must adjust URE and URE equivalents to reflect all the deductions and adjustments required under § 628.22(a), (b) , and (c), and must use the denominator of the tier 1 leverage ratio.(5)Permanent capital ratio. A System institution's permanent capital ratio is the ratio of the institution's permanent capital to its total risk-adjusted asset base as reported on the institution's Call Report, calculated in accordance with the regulations in part 615, subpart H, of this chapter.(e)Capital adequacy.(1) Notwithstanding the minimum requirements in this part, a System institution must maintain capital commensurate with the level and nature of all risks to which the System institution is exposed.
