Regulatory Matters And Capital Adequacy [Abstract] |
Regulatory Matters and Capital Adequacy | REGULATORY MATTERS AND CAPITAL ADEQUACY We are supervised and regulated by the Board of Governors of the Federal Reserve and are subject to the Federal Reserve’s requirements for risk-based capital and leverage ratios. Our U.S. bank subsidiary, AENB, is subject to supervision and regulation, including regulatory capital and leverage requirements, by the OCC. Under the risk-based capital guidelines of the Federal Reserve, we are required to maintain minimum ratios of CET1, Tier 1 and Total (Tier 1 plus Tier 2) capital to risk-weighted assets, as well as a minimum Tier 1 leverage ratio (Tier 1 capital to average adjusted on-balance sheet assets). Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional, discretionary actions by regulators, that, if undertaken, could have a direct material effect on our operating activities. As of December 31, 2023 and 2022, we met all capital requirements to which we were subject and maintained regulatory capital ratios in excess of those required to qualify as well capitalized. The following table presents the regulatory capital ratios:

(a)Capital ratios reported using Basel III capital definitions and risk-weighted assets using the Basel III standardized approach. (b)Represents requirements for bank holding companies and banking subsidiaries to be considered “well capitalized” pursuant to regulations issued under the Federal Reserve Regulation Y and the Federal Deposit Insurance Corporation Improvement Act, respectively. There is no CET1 capital ratio or Tier 1 leverage ratio requirement for a bank holding company to be considered “well capitalized.” (c)As defined by the regulations issued by the Federal Reserve and OCC. (d)Represents Basel III minimum capital requirement and applicable regulatory buffers as defined by the federal banking regulators, which includes the stress capital buffer for American Express Company and the capital conservation buffer for American Express National Bank. RESTRICTED NET ASSETS OF SUBSIDIARIES Certain of our subsidiaries are subject to restrictions on the transfer of net assets under debt agreements and regulatory requirements. These restrictions have not had any effect on our shareholder dividend policy and management does not anticipate any impact in the future. Procedures exist to transfer net assets between the Company and its subsidiaries, while ensuring compliance with the various contractual and regulatory constraints. As of December 31, 2023, the aggregate amount of net assets of subsidiaries that are restricted to be transferred was approximately $13.6 billion. BANK HOLDING COMPANY DIVIDEND RESTRICTIONS We are limited in our ability to pay dividends by the Federal Reserve, which could prohibit a dividend that would be considered an unsafe or unsound banking practice. It is the policy of the Federal Reserve that bank holding companies generally should pay dividends on preferred and common stock only out of net income available to common shareholders generated over the past year, and only if prospective earnings retention is consistent with the organization’s current and expected future capital needs, asset quality and overall financial condition. Moreover, bank holding companies are required by statute to be a source of strength to their insured depository institution subsidiaries and should not maintain dividend levels that undermine their ability to do so. On an annual basis, we are required to develop and maintain a capital plan, which includes planned dividends. We may be subject to limitations and restrictions on our dividends, if, among other things, (i) our regulatory capital ratios do not satisfy applicable minimum requirements and buffers or (ii) we are required to resubmit our capital plan. BANK DIVIDEND RESTRICTIONS In the year ended December 31, 2023, AENB paid dividends from retained earnings to its parent of $3.6 billion. AENB is limited in its ability to pay dividends by banking statutes, regulations and supervisory policy. In general, applicable federal and state banking laws prohibit, without first obtaining regulatory approval, insured depository institutions, such as AENB, from making dividend distributions if such distributions are not paid out of available retained earnings or would cause the institution to fail to meet capital adequacy standards. If AENB’s risk-based capital ratios do not satisfy minimum regulatory requirements and applicable buffers, it will face graduated constraints on dividends and other capital distributions. In determining the dividends to pay its parent, AENB must also consider the effects on applicable risk-based capital and leverage ratio requirements, as well as policy statements of the federal regulatory agencies. In addition, AENB’s banking regulators have authority to limit or prohibit the payment of a dividend by AENB under a number of circumstances, including if, in the banking regulator’s opinion, payment of a dividend would constitute an unsafe or unsound banking practice in light of the financial condition of the banking organization.
