We are subject to extensive federal and state regulation and supervision. Federal and state laws and regulations govern numerous matters affecting us, including changes in the ownership or control of banks and bank holding companies; maintenance of adequate capital and the financial condition of a financial institution; permissible types, amounts and terms of extensions of credit and investments; the manner in which we conduct mortgage banking activities; permissible non-banking activities; the level of reserves against deposits; and restrictions on dividend payments. The FDIC and the banking divisions or departments of states in which we are licensed to do business have the power to issue consent orders to prevent or remedy unsafe or unsound practices or violations of law by banks subject to their regulation, and the Federal Reserve possesses similar powers with respect to bank holding companies. In addition, WTA, a registered investment advisor subsidiary, is subject to regulation under federal and state securities laws and fiduciary laws. These and other restrictions limit the manner in which we may conduct business and obtain financing.
Federal regulations establish minimum capital requirements for insured depository institutions, including minimum risk-based capital and leverage ratios, and define "capital" for calculating these ratios. The minimum capital requirements are: (i) a common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 to risk-based assets capital ratio of 6%; (iii) a total capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. The regulations also establish a "capital conservation buffer" of 2.5%. An institution will be subject to limitations on paying dividends, engaging in share repurchases and paying discretionary bonuses if its capital level falls below the capital conservation buffer amount. The application of these capital requirements could, among other things, require us to maintain higher capital resulting in lower returns on equity, and we may be required to obtain additional capital to comply or result in regulatory actions if we are unable to comply with such requirements.
The laws, rules, regulations, and supervisory guidance and policies applicable to us are subject to regular modification and change. These changes could adversely and materially impact us. Such changes could, among other things, subject us to additional costs, including costs of compliance; limit the types of financial services and products we may offer; and/or increase the ability of non-banks to offer competing financial services and products. Failure to comply with laws, regulations, policies, or supervisory guidance could result in enforcement and other legal actions by federal and state authorities, including criminal and civil penalties, the loss of FDIC insurance, revocation of a banking charter or registration as an investment adviser, other sanctions by regulatory agencies, civil money penalties, and/or reputational damage, which could have a material adverse effect on our business, financial condition, and results of operations.
