⁽¹⁾ Minimum capital ratios are subject to a capital conservation buffer. In order to avoid limitations on distributions, including dividend payments, and certain discretionary bonus payments to executive officers, an institution must hold a capital conservation buffer above its minimum risk-based capital requirements. This capital conservation buffer is calculated as the lowest of the differences between the actual CET1 ratio, Tier 1 Risk-Based Capital Ratio, and Total Risk-Based Capital ratio and the corresponding minimum ratios. At September 30, 2018, the required minimum capital conservation buffer was 1.875%, and will increase by 0.625% and be fully phased-in on January 1, 2019 at 2.50%. At September 30, 2018, the capital conservation buffers of the Company and IBERIABANK were 4.42% and 3.89%, respectively.
