Bank of Marin: Regulatory Capital and Risk-Weighted Assets
As of 2Q26, from Call Report Schedule RC-R.
Capital conservation buffer: 6.61% (2Q26), against the 2.50% a bank must hold above each risk-based minimum to pay dividends and discretionary bonuses without limits. The buffer is the smallest of the three cushions over the minimums; here the binding ratio is Total capital. The bank clears the requirement. Filed figure: 6.61% (RCOAH311).

Risk-weighted assets by exposure category, 2Q26
Each category's exposure is filed across the risk-weight columns of Schedule RC-R Part II; its risk-weighted assets are each allocation times its weight. The average risk weight says how much capital a dollar of that exposure consumes.

Peer ratios use the same basis as this bank: the standardized column of Schedule RC-R where served, the filed summary otherwise. Similar banks are the nearest banks by size in the same asset tier.
Source: FFIEC Call Report Schedule RC-R, Parts I and II, as filed. Well capitalized means at least 6.5% CET1, 8% Tier 1, 10% total capital and 5% leverage under the prompt corrective action rules; a community bank leverage ratio filer must instead hold the leverage ratio its framework requires. The same figures are in the API at /api/v1/banks/1436204/regulatory-capital/ and in the Excel workbook. Next: the capital tab, the peer group page, or the full profile.
