Schedule of compliance with regulatory capital requirements under banking regulations

Certain Basel III requirements are subject to phase-in through 2019, and were applied to this report of actual regulatory ratios. In addition, the Company has declared itself as an “AOCI opt-out” institution, which means the Company is not required to recognize within regulatory capital the impacts of net unrealized gains and losses included within AOCI for available for sale securities, accumulated net gains and losses on cash-flow hedges, net gains and losses on certain defined benefit pension plan assets, and net unrealized gains and losses on securities held to maturity.
