Swbsidiary Bank The amounts of dividends that BOK Financial's subsidiary bank can declare and the amounts of loans the subsidiary bank carn extend to affiliates are limited by various federal banking regulations and state corporate law. Generally, dividends declared during a calendar year are limited to net profits, as defined, for the year plus retained profits for the preceding two years. The amounts of dividends are further restricted by minimum capital requirements. Regulatory Capital BOK Financial and the subsidiary banks are subject to various capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and additional discretionary actions by regulators that could have a material effect on BOK Financial's operations.

New capital rules were effective for BOK Financial on January 1,2015. Components of these rules will phase in through January 1, 2019. A bank falling below the minimum capital requirements, incuding the capital conservation buffer, would be subject to regulatory restrictions on capital distributions (including but not limited to dividends and share repurchases) and executive bonus payments.
