| Regulatory Requirements | |
| Description of regulatory requirements on capital adequacy | In addition to the minimum risk-based capital ratio requirements, the Firm is subject to the following buffers in 2019: ● A greater than 2.5% Common Equity Tier 1 capital conservation buffer; ● The Common Equity Tier 1 G-SIB capital surcharge, currently at 3%; and ● Up to a 2.5% Common Equity Tier 1 CCyB, currently set by U.S. banking agencies at zero. |
| Description of possible effects of noncompliance | In 2018 and 2017, each of the buffers was 75% and 50%, respectively, of the fully phased-in 2019 requirement noted above. Failure to maintain the buffers would result in restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. |
