Regulatory Requirements [Text Block] | Regulatory Requirements Restrictions on the transfer of funds exist under regulatory requirements applicable to certain of the Company’s subsidiaries. As of December 31, 2020, the aggregate amount of unrestricted net assets was approximately $3.1 billion. The National Association of Insurance Commissioners (“NAIC”) defines Risk-Based Capital (“RBC”) requirements for insurance companies. The RBC requirements are used by the NAIC and state insurance regulators to identify companies that merit regulatory actions designed to protect policyholders. These requirements apply to the Company’s life insurance companies. The Company’s life insurance companies each met their respective minimum RBC requirements. The Company’s life insurance companies are required to prepare statutory financial statements in accordance with the accounting practices prescribed or permitted by the insurance departments of their respective states of domicile, which vary materially from GAAP. Prescribed statutory accounting practices include publications of the NAIC, as well as state laws, regulations and general administrative rules. The more significant differences from GAAP include charging policy acquisition costs to expense as incurred, establishing annuity and insurance reserves using different actuarial methods and assumptions, valuing investments on a different basis and excluding certain assets from the balance sheet by charging them directly to surplus, such as a portion of the net deferred income tax assets. RiverSource Life received approval from the Minnesota Department of Commerce to apply a permitted statutory accounting practice, effective July 1, 2017 through June 30, 2019, for certain derivative instruments used to economically hedge the interest rate exposure of certain variable annuity products that do not qualify for statutory hedge accounting. The permitted practice was intended to mitigate the impact to statutory surplus from the misalignment between variable annuity statutory reserves, which are not carried at fair value, and the fair value of derivatives used to economically hedge the interest rate exposure of non-life contingent living benefit guarantees. The permitted practice allowed RiverSource Life to defer a portion of the change in fair value, net investment income and realized gains or losses generated from designated derivatives to the extent the amounts do not offset the current period interest-rate related change in the variable annuity statutory reserve liability. The deferred amount could be amortized over ten years using the straight-line method with the ability to accelerate amortization at management’s discretion. As of June 30, 2019, RiverSource Life elected to accelerate amortization of the net deferred amount associated with its permitted practice. State insurance statutes contain limitations as to the amount of dividends that insurers may make without providing prior notification to state regulators. For RiverSource Life, payments in excess of unassigned surplus, as determined in accordance with accounting practices prescribed by the State of Minnesota, require advance notice to the Minnesota Department of Commerce, RiverSource Life’s primary regulator, and are subject to potential disapproval. RiverSource Life’s statutory unassigned surplus aggregated $1.3 billion and $326 million as of December 31, 2020 and 2019, respectively. In addition, dividends whose fair market value, together with that of other dividends made within the preceding 12 months, exceed the greater of the previous year’s statutory net gain from operations or 10% of the previous year-end statutory capital and surplus are referred to as “extraordinary dividends.” Extraordinary dividends also require advance notice to the Minnesota Department of Commerce, and are subject to potential disapproval. Statutory capital and surplus for RiverSource Life was $4.8 billion and $2.9 billion as of December 31, 2020 and 2019, respectively. Statutory net gain from operations and net income (loss) are summarized as follows:

Government debt securities of $4 million as of both December 31, 2020 and 2019 held by the Company’s life insurance subsidiaries were on deposit with various states as required by law. Ameriprise Certificate Company (“ACC”) is registered as an investment company under the Investment Company Act of 1940 (the “1940 Act”). ACC markets and sells investment certificates to clients. ACC is subject to various capital requirements under the 1940 Act, laws of the State of Minnesota and understandings with the Securities and Exchange Commission (“SEC”) and the Minnesota Department of Commerce. The terms of the investment certificates issued by ACC and the provisions of the 1940 Act also require the maintenance by ACC of qualified assets. Under the provisions of its certificates and the 1940 Act, ACC was required to have qualified assets (as that term is defined in Section 28(b) of the 1940 Act) in the amount of $6.8 billion and $7.5 billion as of December 31, 2020 and 2019, respectively. ACC had qualified assets of $7.2 billion and $8.0 billion as of December 31, 2020 and 2019, respectively. Threadneedle’s required capital is predominantly based on the requirements specified by its regulator, the Financial Conduct Authority (“FCA”), under its Capital Adequacy Requirements for asset managers. The Company’s broker-dealer subsidiaries are subject to the Uniform Net Capital Rule (Rule 15c3-1) under the Securities Exchange Act of 1934. Rule 15c3-1 provides an “alternative net capital requirement” which American Enterprise Investment Services, Inc. (“AEIS”) and Ameriprise Financial Services, LLC (“AFS”) (significant broker dealers) have elected. Regulations require that minimum net capital, as defined, be equal to the greater of $250 thousand or 2% of aggregate debit items arising from client balances. FINRA may impose certain restrictions, such as restricting withdrawals of equity capital, if a member firm were to fall below a certain threshold or fail to meet minimum net capital requirements. The following table presents the net capital position of both AEIS and AFS:

Ameriprise Trust Company is subject to capital adequacy requirements under the laws of the State of Minnesota as enforced by the Minnesota Department of Commerce. The Company is a savings and loan holding company that is subject to various banking regulations. However, the Company is not currently subject to the risk-based capital requirements of the Federal Reserve Bank because it is substantially engaged in insurance activities. Ameriprise Bank, FSB (“Ameriprise Bank”) is subject to regulation by the Comptroller of Currency (“OCC”) and the Federal Deposit Insurance Corporation in its role as insurer of its deposits.
