Insurance [Abstract]
Regulatory Requirements [Text Block]	Regulatory Requirements The Company’s insurance subsidiaries 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. 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 is 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. As of March 31, 2019 and December 31, 2018, application of this permitted practice resulted in an increase (decrease) to RiverSource Life’s statutory surplus of approximately $(111) million and $92 million, respectively.
