Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation RiverSource Life Insurance Company is a stock life insurance company with one wholly owned stock life insurance company subsidiary, RiverSource Life Insurance Co. of New York (“RiverSource Life of NY”). RiverSource Life Insurance Company is a wholly owned subsidiary of Ameriprise Financial, Inc. (“Ameriprise Financial”). • RiverSource Life Insurance Company is domiciled in Minnesota and holds Certificates of Authority in American Samoa, the District of Columbia and all states except New York. RiverSource Life Insurance Company issues insurance and annuity products. • RiverSource Life of NY is domiciled and holds a Certificate of Authority in New York. RiverSource Life of NY issues insurance and annuity products. RiverSource Life Insurance Company also wholly owns RiverSource Tax Advantaged Investments, Inc. (“RTA”). RTA is a stock company domiciled in Delaware and is a limited partner in affordable housing partnership investments. The accompanying Consolidated Financial Statements include the accounts of RiverSource Life Insurance Company and companies in which it directly or indirectly has a controlling financial interest (collectively, the “Company”). All intercompany transactions and balances have been eliminated in consolidation. In 2017 , the Company recorded the following out-of-period corrections: • a $12 million out-of-period correction related to a variable annuity model assumption that decreased amortization of deferred acquisition costs (“DAC”) by $8 million and decreased benefits, claims, losses and settlement expenses by $4 million . • a $20 million decrease to income tax provision for a reversal of a tax reserve. The impact of these out-of-period corrections was not material to prior period financial statements. The accompanying Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) which vary in certain respects from reporting practices prescribed or permitted by state insurance regulatory authorities as described in Note 15. The Company evaluated events or transactions that may have occurred after the balance sheet date for potential recognition or disclosure through the date the financial statements were issued. No subsequent events or transactions were identified. The Company’s principal products are variable deferred annuities, universal life (“UL”) insurance, including indexed universal life (“IUL”) and variable universal life (“VUL”) insurance, which are issued primarily to individuals. Waiver of premium and accidental death benefit riders are generally available with UL products, in addition to other benefit riders. Variable annuity contract purchasers can choose to add optional benefit riders to their contracts, such as guaranteed minimum death benefit (“GMDB”), guaranteed minimum withdrawal benefit (“GMWB”) and guaranteed minimum accumulation benefit (“GMAB”) riders. The Company also offers immediate annuities, fixed deferred annuities, and traditional life and disability income (“DI”) insurance. The Company issues only non-participating life insurance policies which do not pay dividends to policyholders and contractholders. Nearly all of the Company’s business is sold through the retail channel of Ameriprise Financial Services, LLC (“AFS”) (previously Ameriprise Financial Services, Inc. until January 2020), a subsidiary of Ameriprise Financial. RiverSource Distributors, Inc., a subsidiary of Ameriprise Financial, serves as the principal underwriter and distributor of variable annuity and life insurance products issued by the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Principles of Consolidation A variable interest entity (“VIE”) is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest (including substantive voting rights, the obligation to absorb the entity’s losses, or the rights to receive the entity’s returns) or has equity investors that do not provide sufficient financial resources for the entity to support its activities. Voting interest entities (“VOEs”) are those entities that do not qualify as a VIE. The Company consolidates VOEs in which it holds a greater than 50% voting interest. The Company generally accounts for entities using the equity method when it holds a greater than 20% but less than 50% voting interest or when the Company exercises significant influence over the entity. All other investments that are not reported at fair value as trading or Available-for-Sale securities are accounted for under the cost method when the Company owns less than a 20% voting interest and does not exercise significant influence. A VIE is consolidated by the reporting entity that determines it has both: • the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and • the obligation to absorb potentially significant losses or the right to receive potentially significant benefits to the VIE. All VIEs are assessed for consolidation under this framework. When evaluating entities for consolidation, the Company considers its contractual rights in determining whether it has the power to direct the activities of the VIE that most significantly impact the VIEs economic performance. In determining whether the Company has this power, it considers whether it is acting in a role that enables it to direct the activities that most significantly impact the economic performance of an entity or if it is acting in an agent role. In determining whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the Company considers an analysis of its rights to receive benefits such as investment returns and its obligation to absorb losses associated with any investment in the VIE in conjunction with other qualitative factors. Management and incentive fees that are at market and commensurate with the level of services provided, and where the Company does not hold other interests in the VIE that would absorb more than an insignificant amount of the VIE’s expected losses or receive more than an insignificant amount of the VIE’s expected residual returns, are not considered a variable interest and are excluded from the analysis. The consolidation guidance has a scope exception for reporting entities with interests in registered money market funds which do not have an explicit support agreement. Amounts Based on Estimates and Assumptions Accounting estimates are an integral part of the Consolidated Financial Statements. In part, they are based upon assumptions concerning future events. Among the more significant are those that relate to investment securities valuation and recognition of other-than-temporary impairments, DAC and the corresponding recognition of DAC amortization, valuation of derivative instruments and hedging activities, litigation reserves, future policy benefits and claims reserves and income taxes and the recognition of deferred tax assets and liabilities. These accounting estimates reflect the best judgment of management and actual results could differ. Investments Available-for-Sale Securities Available -for-Sale securities are carried at fair value with unrealized gains (losses) recorded in accumulated other comprehensive income (“AOCI”), net of impacts to DAC, deferred sales inducement costs (“DSIC”), unearned revenue, benefit reserves, reinsurance recoverables and income taxes. Gains and losses are recognized on a trade date basis in the Consolidated Statements of Income upon disposition of the securities. When the fair value of an investment is less than its amortized cost, the Company assesses whether or not: (i) it has the intent to sell the security (made a decision to sell) or (ii) it is more likely than not that the Company will be required to sell the security before its anticipated recovery. If either of these conditions exist, an other-than-temporary impairment is considered to have occurred and the Company recognizes an other-than-temporary impairment for the difference between the investment’s amortized cost and its fair value through earnings. For securities that do not meet the above criteria and the Company does not expect to recover a security’s amortized cost, the security is also considered other-than-temporarily impaired. For these securities, the Company separates the total impairment into the credit loss component and the amount of the loss related to other factors. The amount of the total other-than-temporary impairment related to credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to other factors is recognized in other comprehensive income (“OCI”), net of impacts to DAC, DSIC, unearned revenue, benefit reserves, reinsurance recoverables and income taxes. For Available-for-Sale securities that have recognized an other-than-temporary impairment through earnings, the difference between the amortized cost and the cash flows expected to be collected is accreted as interest income if through subsequent evaluation there is a sustained increase in the cash flow expected. Subsequent increases and decreases in the fair value of Available-for-Sale securities are included in OCI. The Company provides a supplemental disclosure on the face of its Consolidated Statements of Income that presents: (i) total other-than-temporary impairment losses recognized during the period and (ii) the portion of other-than-temporary impairment losses recognized in OCI. The sum of these amounts represents the credit-related portion of other-than-temporary impairments that were recognized in earnings during the period. The portion of other-than-temporary losses recognized in OCI includes: (i) the portion of other-than-temporary impairment losses related to factors other than credit recognized during the period and (ii) reclassifications of other-than-temporary impairment losses previously determined to be related to factors other than credit that are determined to be credit-related in the current period. The amount presented on the Consolidated Statements of Income as the portion of other-than-temporary losses recognized in OCI excludes subsequent increases and decreases in the fair value of these securities. For all securities that are considered temporarily impaired, the Company does not intend to sell these securities (has not made a decision to sell) and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. The Company believes that it will collect all principal and interest due on all investments that have amortized cost in excess of fair value that are considered only temporarily impaired. Factors the Company considers in determining whether declines in the fair value of fixed maturity securities are other-than-temporary include: (i) the extent to which the market value is below amortized cost; (ii) the duration of time in which there has been a significant decline in value; (iii) fundamental analysis of the liquidity, business prospects and overall financial condition of the issuer; and (iv) market events that could impact credit ratings, economic and business climate, litigation and government actions, and similar external business factors. In order to determine the amount of the credit loss component for corporate debt securities considered other-than-temporarily impaired, a best estimate of the present value of cash flows expected to be collected discounted at the security’s effective interest rate is compared to the amortized cost basis of the security. The significant inputs to cash flow projections consider potential debt restructuring terms, projected cash flows available to pay creditors and the Company’s position in the debtor’s overall capital structure. For structured investments (e.g., residential mortgage backed securities, commercial mortgage backed securities and asset backed securities), the Company also considers factors such as overall deal structure and its position within the structure, quality of underlying collateral, delinquencies and defaults, loss severities, recoveries, prepayments and cumulative loss projections in assessing potential other-than-temporary impairments of these investments. Based upon these factors, securities that have indicators of potential other-than-temporary impairment are subject to detailed review by management. Securities for which declines are considered temporary continue to be monitored by management until management determines there is no current risk of an other-than-temporary impairment. Other Investments Other investments primarily reflect the Company’s interests in affordable housing partnerships and syndicated loans. Affordable housing partnerships are accounted for under the equity method. Financing Receivables Mortgage Loans and Syndicated Loans Mortgage loans, net reflect the Company’s interest in commercial mortgage loans less the related allowance for loan losses. Syndicated loans represent the Company’s investment in below investment grade loan syndications. Mortgage loans and syndicated loans are stated at amortized cost, net of allowances for loan losses. Interest income is accrued on the unpaid principal balances of the loans as earned. Policy Loans Policy loans include life insurance policy and annuity loans and are reported at the unpaid principal balance, plus accrued interest. When originated, policy loan balances do not exceed the cash surrender value of the underlying products. As there is minimal risk of loss related to these loans, the Company does not record an allowance for loan losses for policy loans. Deposit Receivable For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability related to insurance risk in accordance with applicable accounting standards. If the Company determines that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, the Company records the agreement using the deposit method of accounting. Deposits made are included in other receivables. As amounts are received, consistent with the underlying contracts, the deposit receivable is adjusted. The deposit receivable is accreted using the interest method and the accretion is reported in other revenues. See Note 7 for additional information on the deposit receivable. Nonaccrual Loans Generally , loans are evaluated for or placed on nonaccrual status when either the collection of interest or principal has become 90 days past due or is otherwise considered doubtful of collection. When a loan is placed on nonaccrual status, unpaid accrued interest is reversed. Interest payments received on loans on nonaccrual status are generally applied to principal unless the remaining principal balance has been determined to be fully collectible. Commercial mortgage loans are evaluated for impairment when the loan is considered for nonaccrual status, restructured or foreclosure proceedings are initiated on the property. If it is determined that the fair value is less than the current loan balance, it is written down to fair value less estimated selling costs. Foreclosed property is recorded as real estate owned in other investments. Allowance for Loan Losses Management determines the adequacy of the allowance for loan losses based on the overall loan portfolio composition, recent and historical loss experience, and other pertinent factors, including when applicable, internal risk ratings, loan-to-value (“LTV”) ratios, FICO scores of the borrower, debt service coverage and occupancy rates, along with current economic and market conditions. This evaluation is inherently subjective as it requires estimates, which may be susceptible to significant change. The Company determines the amount of the allowance based on management’s assessment of relative risk characteristics of the loan portfolio. The allowance is recorded for homogeneous loan categories on a pool basis, based on an analysis of product mix and risk characteristics of the portfolio, including geographic concentration, bankruptcy experiences, and historical losses, adjusted for current trends and market conditions. While the Company attributes portions of the allowance to specific loan pools as part of the allowance estimation process, the entire allowance is available to absorb losses inherent in the total loan portfolio. The allowance is increased through provisions charged to net realized investment gains (losses) and reduced/increased by net charge-offs/recoveries. Impaired Loans The Company considers a loan to be impaired when, based on current information and events, it is probable the Company will not be able to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans may also include loans that have been modified in troubled debt restructurings as a concession to borrowers experiencing financial difficulties. Management evaluates for impairment all restructured loans and loans with higher impairment risk factors. Factors used by the Company to determine whether all amounts due on commercial mortgage loans will be collected, include but are not limited to, the financial condition of the borrower, performance of the underlying properties, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on property type and geographic location. The impairment recognized is measured as the excess of the loan’s recorded investment over: (i) the present value of its expected principal and interest payments discounted at the loan’s effective interest rate, (ii) the fair value of collateral or (iii) the loan’s observable market price. Restructured Loans A loan is classified as a restructured loan when the Company makes certain concessionary modifications to contractual terms for borrowers experiencing financial difficulties. When the interest rate, minimum payments, and/or due dates have been modified in an attempt to make the loan more affordable to a borrower experiencing financial difficulties, the modification is considered a troubled debt restructuring. Generally, performance prior to the restructuring or significant events that coincide with the restructuring are considered in assessing whether the borrower can meet the new terms which may result in the loan being returned to accrual status at the time of the restructuring or after a performance period. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains on nonaccrual status. Cash and Cash Equivalents Cash equivalents include highly liquid investments with original or remaining maturities at the time of purchase of 90 days or less. Reinsurance The Company cedes insurance risk to other insurers under reinsurance agreements. The Company evaluates the financial condition of its reinsurers prior to entering into new reinsurance contracts and on a periodic basis during the contract term. Reinsurance premiums paid and benefits received are accounted for consistently with the basis used in accounting for the policies from which risk is reinsured and consistently with the terms of the reinsurance contracts. Reinsurance premiums for traditional life, long term care (“LTC”) and DI, net of the change in any prepaid reinsurance asset, are reported as a reduction of premiums. UL and VUL reinsurance premiums are reported as a reduction of policy and contract charges. In addition, for UL and VUL insurance policies, the net cost of reinsurance ceded, which represents the discounted amount of the expected cash flows between the reinsurer and the Company, is classified as an asset or contra asset and amortized over the estimated life of the policies in proportion to the estimated gross profits (“EGPs”) and is subject to retrospective adjustment in a manner similar to retrospective adjustment of DAC. The assumptions used to project the expected cash flows are consistent with those used for DAC valuation for the same contracts. Changes in the net cost of reinsurance are reflected as a component of policy and contract charges. Reinsurance recoveries are reported as components of benefits, claims, losses and settlement expenses. Insurance liabilities are reported before the effects of reinsurance. Policyholder account balances, future policy benefits and claims recoverable under reinsurance contracts are recorded as reinsurance recoverables. The Company also assumes life insurance and fixed annuity risk from other insurers in limited circumstances. Reinsurance premiums received and benefits paid are accounted for consistently with the basis used in accounting for the policies from which risk is reinsured and consistently with the terms of the reinsurance contracts. Liabilities for assumed business are recorded within policyholder account balances, future policy benefits and claims. See Note 9 for additional information on reinsurance. Land , Buildings, Equipment and Software Land , buildings, equipment and internally developed or purchased software are carried at cost less accumulated depreciation or amortization and are reflected within other assets. The Company uses the straight-line method of depreciation and amortization over periods ranging from three to 39 years . As of December 31, 2019 and 2018 , land, buildings, equipment and software were $129 million and $135 million , respectively, net of accumulated depreciation of $189 million and $174 million , respectively. Depreciation and amortization expense for the years ended December 31, 2019 , 2018 and 2017 was $16 million , $15 million and $15 million , respectively. Derivative Instruments and Hedging Activities Freestanding derivative instruments are recorded at fair value and are reflected in other assets or other liabilities. The Company’s policy is to not offset fair value amounts recognized for derivatives and collateral arrangements executed with the same counterparty under the same master netting arrangement. The accounting for changes in the fair value of a derivative instrument depends on its intended use and the resulting hedge designation, if any. The Company primarily uses derivatives as economic hedges that are not designated as accounting hedges or do not qualify for hedge accounting treatment. The Company occasionally designates derivatives as (i) hedges of changes in the fair value of assets, liabilities, or firm commitments (“fair value hedges”) or (ii) hedges of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedges”). Derivative instruments that are entered into for hedging purposes are designated as such at the time the Company enters into the contract. For all derivative instruments that are designated for hedging activities, the Company documents all of the hedging relationships between the hedge instruments and the hedged items at the inception of the relationships. Management also documents its risk management objectives and strategies for entering into the hedge transactions. The Company assesses, at inception and on a quarterly basis, whether derivatives designated as hedges are highly effective in offsetting the fair value or cash flows of hedged items. If it is determined that a derivative is no longer highly effective as a hedge, the Company will discontinue the application of hedge accounting . For derivative instruments that do not qualify for hedge accounting or are not designated as accounting hedges, changes in fair value are recognized in current period earnings. Changes in fair value of derivatives are presented in the Consolidated Statements of Income based on the nature and use of the instrument. Changes in fair value of derivatives used as economic hedges are presented in the Consolidated Statements of Income with the corresponding change in the hedged asset or liability. For derivative instruments that qualify as fair value hedges, changes in the fair value of the derivatives, as well as changes in the fair value of the hedged assets, liabilities or firm commitments, are recognized on a net basis in current period earnings. The carrying value of the hedged item is adjusted for the change in fair value from the designated hedged risk. If a fair value hedge designation is removed or the hedge is terminated prior to maturity, previous adjustments to the carrying value of the hedged item are recognized into earnings over the remaining life of the hedged item. For derivative instruments that qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instruments is reported in AOCI and reclassified into earnings when the hedged item or transaction impacts earnings. The amount that is reclassified into earnings is presented in the Consolidated Statements of Income with the hedged instrument or transaction impact. Any ineffective portion of the gain or loss is reported in current period earnings as a component of net investment income. If a hedge designation is removed or a hedge is terminated prior to maturity, the amount previously recorded in AOCI is reclassified to earnings over the period that the hedged item impacts earnings. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related amounts previously recorded in AOCI are recognized in earnings immediately. The equity component of indexed annuities and IUL obligations are considered embedded derivatives. Additionally, certain annuities contain GMAB and GMWB provisions. The GMAB and the non-life contingent benefits associated with GMWB provisions are also considered embedded derivatives. See Note 13 for information regarding the Company’s fair value measurement of derivative instruments and Note 17 for the impact of derivatives on the Consolidated Statements of Income. Deferred Acquisition Costs The Company incurs costs in connection with acquiring new and renewal insurance and annuity businesses. The portion of these costs which are incremental and direct to the acquisition of a new or renewal insurance policy or annuity contract are deferred. Significant costs capitalized include sales based compensation related to the acquisition of new and renewal insurance policies and annuity contracts, medical inspection costs for successful sales, and a portion of employee compensation and benefit costs based upon the amount of time spent on successful sales. Sales based compensation paid to AFS advisors and employees and third-party distributors is capitalized. Employee compensation and benefits costs which are capitalized relate primarily to sales efforts, underwriting and processing. All other costs which are not incremental direct costs of acquiring an insurance policy or annuity contract are expensed as incurred. The DAC associated with insurance policies or annuity contracts that are significantly modified or internally replaced with another contract are accounted for as contract terminations. These transactions are anticipated in establishing amortization periods and other valuation assumptions. The Company monitors other DAC amortization assumptions, such as persistency, mortality, morbidity, interest margin, variable annuity benefit utilization and maintenance expense levels each quarter and, when assessed independently, each could impact the Company’s DAC balances. The analysis of DAC balances and the corresponding amortization is a dynamic process that considers all relevant factors and assumptions described previously. Unless the Company’s management identifies a significant deviation over the course of the quarterly monitoring, management reviews and updates these DAC amortization assumptions annually in the third quarter of each year. Non-Traditional Long-Duration Products For non-traditional long-duration products (including variable and fixed deferred annuity contracts, UL and VUL insurance products), DAC are amortized based on projections of EGPs over amortization periods equal to the approximate life of the business. EGPs vary based on persistency rates (assumptions at which contractholders and policyholders are expected to surrender, make withdrawals from and make deposits to their contracts), mortality levels, client asset value growth rates (based on equity and bond market performance), variable annuity benefit utilization and interest margins (the spread between earned rates on invested assets and rates credited to contractholder and policyholder accounts) and are management’s best estimates. Management regularly monitors financial market conditions and actual contractholder and policyholder behavior experience and compares them to its assumptions. These assumptions are updated whenever it appears that earlier estimates should be revised. When assumptions are changed, the percentage of EGPs used to amortize DAC might also change. A change in the required amortization percentage is applied retrospectively; an increase in amortization percentage will result in a decrease in the DAC balance and an increase in DAC amortization expense, while a decrease in amortization percentage will result in an increase in the DAC balance and a decrease in DAC amortization expense. The impact on results of operations of changing assumptions can be either positive or negative in any particular period and is reflected in the period in which such changes are made. At each balance sheet date, the DAC balance is adjusted for the effect that would result from the realization of unrealized gains (losses) on securities impacting EGPs, with the related change recognized through AOCI. The client asset value growth rates are the rates at which variable annuity and VUL insurance contract values invested in separate accounts are assumed to appreciate in the future. The rates used vary by equity and fixed income investments. Management reviews and, where appropriate, adjusts its assumptions with respect to client asset value growth rates on a regular basis. The Company typically uses a five-year mean reversion process as a guideline in setting near-term equity fund growth rates based on a long-term view of financial market performance as well as recent actual performance. The suggested near-term equity fund growth rate is reviewed quarterly to ensure consistency with management’s assessment of anticipated equity market performance. DAC amortization expense recorded in a period when client asset value growth rates exceed management’s near-term estimate will typically be less than in a period when growth rates fall short of management’s near-term estimate. Traditional Long-Duration Products For traditional long-duration products (including traditional life and DI insurance products), DAC are generally amortized as a percentage of premiums over amortization periods equal to the premium paying period. The assumptions made in calculating the DAC balance and DAC amortization expense are consistent with those used in determining the liabilities. For traditional life and DI insurance products, the assumptions provide for adverse deviations in experience and are revised only if management concludes experience will be so adverse that DAC are not recoverable. If management concludes that DAC are not recoverable, DAC are reduced to the amount that is recoverable based on best estimate assumptions and there is a corresponding expense recorded in the Consolidated Statements of Income. Deferred Sales Inducement Costs Sales inducement costs consist of bonus interest credits and premium credits added to certain annuity contract and insurance policy values. These benefits are capitalized to the extent they are incremental to amounts that would be credited on similar contracts without the applicable feature. The amounts capitalized are amortized using the same methodology and assumptions used to amortize DAC. DSIC is recorded in other assets and amortization of DSIC is recorded in benefits, claims, losses and settlement expenses. Separate Account Assets and Liabilities Separate account assets represent funds held for the benefit of and separate account liabilities represent the obligation to the variable annuity contractholders and variable life insurance policyholders who have a contractual right to receive the benefits of their contract or policy and bear the related investment risk. Gains and losses on separate account assets accrue directly to the contractholder or policyholder and are not reported in the Company’s Consolidated Statements of Income. Separate account assets are recorded at fair value and separate account liabilities are equal to the assets recognized. Policyholder Account Balances, Future Policy Benefits and Claims The Company establishes reserves to cover the risks associated with non-traditional and traditional long-duration products. Non-traditional long-duration products include variable annuity contracts, fixed annuity contracts and UL and VUL policies. Traditional long-duration products include term life, whole life, DI and LTC insurance products. Guarantees accounted for as insurance liabilities include GMDB, gain gross-up (“GGU”), guaranteed minimum income benefit (“GMIB”) and the life contingent benefits associated with GMWB. In addition, UL and VUL policies with product features that result in profits followed by losses are accounted for as insurance liabilities. Guarantees accounted for as embedded derivatives include GMAB and the non-life contingent benefits associated with GMWB. In addition, the portion of indexed annuities and IUL policies allocated to the indexed account is accounted for as an embedded derivative. Changes in future policy benefits and claims are reflected in earnings in the period adjustments are made. Where applicable, benefit amounts expected to be recoverable from reinsurance companies who share in the risk are separately recorded as reinsurance recoverables. Non-Traditional Long-Duration Products The liabilities for non-traditional long-duration products include fixed account values on variable and fixed annuities and UL and VUL policies, liabilities for guaranteed benefits associated with variable annuities and embedded derivatives for variable annuities, indexed annuities and IUL products. Liabilities for fixed account values on variable and fixed deferred annuities and UL and VUL policies are equal to accumulation values, which are the cumulative gross deposits and credited interest less withdrawals and various charges. A portion of the Company’s UL and VUL policies have product features that result in profits followed by losses from the insurance component of the contract. These profits followed by losses can be generated by the cost structure of the product or secondary guarantees in the contract. The secondary guarantee ensures that, subject to specified conditions, the policy will not terminate and will continue to provide a death benefit even if there is insufficient policy value to cover the monthly deductions and charges. The liability for these future losses is determined by estimating the death benefits in excess of account value and recognizing the excess over the estimated life based on expected assessments (e.g. cost of insurance charges, contractual administrative charges, similar fees and investment margin). See Note 11 for information regarding the liability for contracts with secondary guarantees. Liabilities for indexed annuity products and indexed accounts of IUL products are equal to the accumulation of host contract values covering guaranteed benefits and the fair value of embedded equity options. The GMDB and GGU liability is determined by estimating the expected value of death benefits in excess of the projected contract accumulation value and recognizing the excess over the estimated life based on expected assessments (e.g., mortality and expense fees, contractual administrative charges and similar fees). If elected by the contract owner and after a stipulated waiting period from contract issuance, a GM

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements [Text Block]	Recent Accounting Pronouncements Adoption of New Accounting Standards Leases - Recognition of Lease Assets and Liabilities on Balance Sheet In February 2016, the Financial Accounting Standards Board (“FASB”) updated the accounting standards for leases. The update was issued to increase transparency and comparability for the accounting of lease transactions. The standard requires most lease transactions for lessees to be recorded on the balance sheet as lease assets and lease liabilities and both quantitative and qualitative disclosures about leasing arrangements. The standard was effective for interim and annual periods beginning after December 15, 2018. Entities had the option to adopt the standard using a modified retrospective approach at either the beginning of the earliest period presented or as of the date of adoption. The Company adopted the standard using a modified retrospective approach as of January 1, 2019. The Company also elected the package of practical expedients permitted under the transition guidance within the accounting standard that allows entities to carryforward their historical lease classification and to not reassess contracts for embedded leases among other things. The adoption did not have a material impact on the Company’s consolidated financial condition or results of operations. Income Statement – Reporting Comprehensive Income – Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB updated the accounting standards related to the presentation of tax effects stranded in AOCI. The update allows a reclassification from AOCI to retained earnings for tax effects stranded in AOCI resulting from the Tax Act. The election of the update was optional. The update was effective for fiscal years beginning after December 15, 2018. Entities could record the impacts either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company adopted the standard on January 1, 2019 and elected not to reclassify the stranded tax effects in AOCI. Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities In August 2017, the FASB updated the accounting standards to amend the hedge accounting recognition and presentation requirements. The objectives of the update are to better align the financial reporting of hedging relationships to the economic results of an entity’s risk management activities and simplify the application of the hedge accounting guidance. The update also adds new disclosures and amends existing disclosure requirements. The standard was effective for interim and annual periods beginning after December 15, 2018, and was required to be applied on a modified retrospective basis. The Company adopted the standard on January 1, 2019. The adoption did not have an impact on the Company’s consolidated financial condition or results of operations. Receivables - Nonrefundable Fees and Other Costs - Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB updated the accounting standards to shorten the amortization period for certain purchased callable debt securities held at a premium. Under previous guidance, premiums were generally amortized over the contractual life of the security. The amendments require the premium to be amortized to the earliest call date. The update applies to securities with explicit, non-contingent call features that are callable at fixed prices and on preset dates. The standard was effective for interim and annual periods beginning after December 15, 2018, and was required to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company adopted the standard on January 1, 2019. The adoption did not have a material impact on the Company’s consolidated financial condition or results of operations. Revenue from Contracts with Customers In May 2014, the FASB updated the accounting standards for revenue from contracts with customers. The update provides a five step revenue recognition model for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are in the scope of other standards). The standard also updates the accounting for certain costs associated with obtaining and fulfilling a customer contract and requires disclosure of quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenues and cash flows arising from contracts with customers. The standard was effective for interim and annual periods beginning after December 15, 2017. The standard was permitted to be applied retrospectively for all periods presented or retrospectively with a cumulative-effect adjustment at the date of adoption. The Company adopted the revenue recognition guidance on a retrospective basis on January 1, 2018. The update does not apply to revenue associated with the manufacturing of insurance and annuity products or financial instruments as these revenues are in the scope of other standards. Therefore, the update did not have an impact on these revenues. The Company’s implementation efforts included the identification of revenue within the guidance and the review of the customer contracts to determine the Company’s performance obligation and the associated timing of each performance obligation. The adoption of the standard resulted in the reclassification of certain revenues within total revenues. See Note 4 for new disclosures on revenue from contracts with customers. Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB updated the accounting standards on the recognition and measurement of financial instruments. The update requires entities to carry marketable equity securities, excluding investments in securities that qualify for the equity method of accounting, at fair value with changes in fair value reflected in net income each reporting period. The update affects other aspects of accounting for equity instruments, as well as the accounting for financial liabilities utilizing the fair value option. The update eliminates the requirement to disclose the methods and assumptions used to estimate the fair value of financial assets or liabilities held at cost on the balance sheet and requires entities to use the exit price notion when measuring the fair value of these financial instruments. The standard was effective for interim and annual periods beginning after December 15, 2017. The Company adopted the standard on January 1, 2018 using a modified retrospective approach. The adoption of the standard did not have a material impact on the Company’s consolidated financial condition or results of operations. Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB updated the accounting standards related to disclosures for fair value measurements. The update eliminates the following disclosures: 1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) the policy of timing of transfers between levels of the fair value hierarchy, and 3) the valuation processes for Level 3 fair value measurements. The new disclosures include changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements of instruments held at the end of the reporting period and the range and weighted average used to develop significant unobservable inputs and how the weighted average was calculated. The new disclosures are required on a prospective basis; all other provisions should be applied retrospectively. The update is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted for the entire standard or only the provisions to eliminate or modify disclosure requirements. The Company early adopted the provisions of the standard to eliminate or modify disclosure requirements in the fourth quarter of 2018. The update does not have an impact on the Company’s consolidated financial condition or results of operations. Future Adoption of New Accounting Standards Income Taxes – Simplifying the Accounting for Income Taxes In December 2019, the FASB updated the accounting standards to simplify the accounting for income taxes. The update eliminates certain exceptions to accounting principles related to intraperiod tax allocation (prospective basis), deferred tax liabilities related to outside basis differences (modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption) and year-to-date losses in interim periods (prospective basis). The update also amends existing guidance related to situations when an entity receives a step-up in the tax basis of goodwill (prospective basis), allocation of income tax expense when members of a consolidated tax filing group issue separate financial statements (retrospective basis for all periods presented), interim recognition of enactment of tax laws or rate changes (prospective basis) and franchise taxes and other taxes partially based on income (retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption). The standard is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The method of adoption is noted parenthetically after each amendment above. The Company is currently evaluating the impact of the standard on its consolidated financial condition or results of operations. Financial Services – Insurance – Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the FASB updated the accounting standard related to long-duration insurance contracts. The guidance revises key elements of the measurement models and disclosure requirements for long-duration insurance contracts issued by insurers and reinsurers. The guidance establishes a significant new category of benefit features called market risk benefits that protect the contractholder from other-than-nominal capital market risk and expose the insurer to that risk. Insurers will have to measure market risk benefits at fair value. Market risk benefits include variable annuity guaranteed benefits (i.e. guaranteed minimum death, withdrawal, withdrawal for life, accumulation and income benefits). The portion of the change in fair value attributable to a change in the instrument-specific credit risk of market risk benefits in a liability position will be recorded in OCI. Significant changes also relate to the measurement of the liability for future policy benefits for nonparticipating traditional long-duration insurance contracts and immediate annuities with a life contingent feature include the following: • Insurers will be required to review and update the cash flow assumptions used to measure the liability for future policy benefits rather than using assumptions locked in at contract inception. The review of assumptions to measure the liability for all future policy benefits will be required annually at the same time each year, or more frequently if suggested by experience. The effect of updating assumptions will be measured on a retrospective catch-up basis and presented separate from the ongoing policyholder benefit expense in the statement of operations in the period the update is made. This new unlocking process will be required for the Company’s term and whole life insurance, disability income, long term care insurance and immediate annuities with a life contingent feature. • The discount rate used to measure the liability for future policy benefits will be standardized. The current requirement to use a discount rate reflecting expected investment yields will change to an upper-medium grade (low credit risk) fixed income corporate instrument yield (generally interpreted as an “A” rating) reflecting the duration characteristics of the liability. Entities will be required to update the discount rate at each reporting date with the effect of discount rate changes reflected in OCI. • The current premium deficiency test is being replaced with a net premium ratio cap of 100%. If the net premium ratio (i.e. the ratio of the present value of total expected benefits and related expenses to the present value of total expected premiums) exceeds 100%, insurers are required to recognize a loss in the statement of operations in the period. Contracts from different issue years will no longer be permitted to be grouped to determine contracts in a loss position. In addition, the update requires DAC and DSIC relating to all long-duration contracts and most investment contracts to be amortized on a straight-line basis over the expected life of the contract independent of profit emergence. Under the new guidance, interest will not accrue to the deferred balance and DAC and DSIC will not be subject to an impairment test. The update requires significant additional disclosures, including disaggregated rollforwards of the liability for future policy benefits, policyholder account balances, market risk benefits, DAC and DSIC, as well as qualitative and quantitative information about expected cash flows, estimates and assumptions. The update is effective for interim and annual periods beginning after December 15, 2021. The standard should be applied to the liability for future policy benefits and DAC and DSIC on a modified retrospective basis and applied to market risk benefits on a retrospective basis with the option to apply full retrospective transition if certain criteria are met. Early adoption is permitted. The Company is currently evaluating the impact of the standard on its consolidated financial condition, results of operations and disclosures. Intangibles – Goodwill and Other – Internal-Use Software – Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2018, the FASB updated the accounting standards related to customer’s accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is a service contract. The update requires implementation costs for a CCA to be evaluated for capitalization using the same approach as implementation costs associated with internal-use software. The update also addresses presentation, measurement and impairment of capitalized implementation costs in a CCA that is a service contract. The update requires new disclosures on the nature of hosting arrangements that are service contracts, significant judgements made when applying the guidance and quantitative disclosures, including amounts capitalized, amortized and impaired. The update is effective for interim and annual periods beginning after December 15, 2019, and can be applied either prospectively or retrospectively. The Company adopted the standard using a prospective approach on January 1, 2020. The adoption did not have an impact on the Company’s consolidated financial condition or results of operations. Financial Instruments – Credit Losses – Measurement of Credit Losses on Financial Instruments In June 2016, the FASB updated the accounting standards related to accounting for credit losses on certain types of financial instruments. The update replaces the current incurred loss model for estimating credit losses with a new model that requires an entity to estimate the credit losses expected over the life of the asset. Generally, the initial estimate of the expected credit losses and subsequent changes in the estimate will be reported in current period earnings and recorded through an allowance for credit losses on the balance sheet. The current credit loss model for Available-for-Sale debt securities does not change; however, the credit loss calculation and subsequent recoveries are required to be recorded through an allowance. The standard is effective for interim and annual periods beginning after December 15, 2019. A modified retrospective cumulative adjustment to retained earnings should be recorded as of the first reporting period in which the guidance is effective for loans, receivables, and other financial instruments subject to the new expected credit loss model. Prospective adoption is required for establishing an allowance related to Available-for-Sale debt securities, certain beneficial interests, and financial assets purchased with a more-than-insignificant amount of credit deterioration since origination. The Company adopted the standard on January 1, 2020. The adoption of this update did not have a material impact on the Company’s consolidated financial condition or results of operations.

The following discussion describes the nature, timing, and uncertainty of revenues and cash flows arising from the Company’s contracts with customers. Policy and contract charges The Company earns revenue for providing distribution-related services to affiliated and unaffiliated mutual funds that are available as underlying investments in its variable annuity and variable life insurance products. The performance obligation is satisfied at the time the mutual fund is distributed. Revenue is recognized over the time the mutual fund is held in the variable product and is generally earned based on a fixed rate applied, as a percentage, to the net asset value of the fund. The revenue is not recognized at the time of sale because it is variably constrained due to factors outside the Company’s control, including market volatility and how long the fund(s) remain in the insurance policy or annuity contract. The revenue will not be recognized until it is probable that a significant reversal will not occur. These fees are accrued and collected on a monthly basis. Other revenues Administrative fees The Company earns revenue for providing customer support, contract servicing and administrative services for affiliated and unaffiliated mutual funds that are available as underlying instruments in its variable annuity and variable life insurance products. The transfer agent and administration revenue is earned daily based on a fixed rate applied, as a percentage, to assets under management. These performance obligations are considered a series of distinct services that are substantially the same and are satisfied each day over the contract term. These fees are accrued and collected on a monthly basis. Other fees The Company earns revenue for providing affiliated and unaffiliated partners an opportunity to educate the financial advisors of its affiliate, AFS, that sell the Company's products as well as product and marketing personnel to support the offer, sale and servicing of funds within the Company's variable annuity and variable life insurance products. These payments allow the parties to train and support the advisors, explain the features of their products, and distribute marketing and educational materials. The affiliated revenue is earned based on a rate, updated at least annually, which is applied, as a percentage, to the market value of assets invested. The unaffiliated revenue is earned based on a fixed rate applied, as a percentage, to the market value of assets invested. These performance obligations are considered a series of distinct services that are substantially the same and are satisfied each day over the contract term. These fees are accrued and collected on a monthly basis. Receivables Receivables for revenue from contracts with customers are recognized when the performance obligation is satisfied and the Company has an unconditional right to the revenue. Receivables related to revenues from contracts with customers were $55 million and $49 million as of December 31, 2019 and 2018 , respectively.

Variable Interest Entity, Nonconsolidated, Carrying Amount, Assets and Liabilities, Net [Abstract]
Variable Interest Entities [Text Block]	Variable Interest Entities The Company is a limited partner in affordable housing partnerships that qualify for government-sponsored low income housing tax credit programs and partnerships that invest in multi-family residential properties that were originally developed with an affordable housing component. The Company has determined it is not the primary beneficiary and therefore does not consolidate these partnerships. A majority of the limited partnerships are VIEs. The Company’s maximum exposure to loss as a result of its investment in the VIEs is limited to the carrying value. The carrying value is reflected in other investments and was $270 million $352 million as of December 31, 2019 and 2018 , respectively. The Company had a $15 million and $43 million liability recorded as of December 31, 2019 and 2018 , respectively, related to original purchase commitments not yet remitted to the VIEs. The Company has not provided any additional support and is not contractually obligated to provide additional support to the VIEs beyond the funding commitments. The Company invests in structured investments which are considered VIEs for which it is not generally the sponsor. These structured investments typically invest in fixed income instruments and are primarily managed by third parties and include asset backed securities, commercial and residential mortgage backed securities. The Company classifies these investments as Available-for-Sale securities. The Company has determined that it is not the primary beneficiary of these structures due to the lack of power to direct the activities that most significantly impact the economic performance, size of the Company’s investment in the entities and position in the capital structure of these entities. The Company’s maximum exposure to loss as a result of its investment in these structured investments is limited to its amortized cost. The Company has no

Amount includes unrealized gains and losses on impaired securities subsequent to the initial impairment measurement date. These amounts are included in gross unrealized gains and losses as of the end of the period. As of December 31, 2019 and 2018 , investment securities with a fair value of $1.9 billion and $1.4 billion , respectively, were pledged to meet contractual obligations under derivative contracts and short-term borrowings, of which $576 million and $405 million , respectively, may be sold, pledged or rehypothecated by the counterparty. As of December 31, 2019 and 2018 , fixed maturity securities comprised approximately 83% and 84% , respectively, of the Company’s total investments. Rating agency designations are based on the availability of ratings from Nationally Recognized Statistical Rating Organizations (“NRSROs”), including Moody’s Investors Service (“Moody’s”), Standard & Poor’s Ratings Services (“S&P”) and Fitch Ratings Ltd. (“Fitch”). The Company uses the median of available ratings from Moody’s, S&P and Fitch, or if fewer than three ratings are available, the lower rating is used. When ratings from Moody’s, S&P and Fitch are unavailable, the Company may utilize ratings from other NRSROs or rate the securities internally. As of December 31, 2019 and 2018 , approximately $615 million and $706 million , respectively, of securities were internally rated by CMIA, an affiliate of the Company, using criteria similar to those used by NRSROs. A summary of fixed maturity securities by rating was as follows: Ratings December 31, 2019 December 31, 2018 Amortized Cost Fair Percent of Amortized Fair Percent of (in millions, except percentages) AAA $ 6,771 $ 6,950 33 % $ 6,602 $ 6,499 30 % AA 1,176 1,374 7 1,310 1,455 7 A 2,695 3,157 15 2,550 2,776 13 BBB 7,709 8,626 41 9,745 9,945 46 Below investment grade 760 795 4 892 853 4 Total fixed maturities $ 19,111 $ 20,902 100 % $ 21,099 $ 21,528 100 % As of December 31, 2019 and 2018 , approximately 39% and 34% , respectively, of securities rated AAA were GNMA, FNMA and FHLMC mortgage backed securities.

Receivables [Abstract]
Financing Receivables	Financing Receivables The Company’s financing receivables include commercial mortgage loans, syndicated loans, policy loans and the deposit receivable. Syndicated loans are reflected in other investments. The deposit receivable is reflected in other receivables. Allowance for Loan Losses Policy loans do not exceed the cash surrender value of the policy at origination. As there is minimal risk of loss related to policy loans, the Company does not record an allowance for loan losses for policy loans. The Company does not have an allowance for loan losses for the deposit receivable as the receivable is supported by a trust and there is minimal risk of loss. The following table presents a rollforward of the allowance for loan losses for the years ended and the ending balance of the allowance for loan losses by impairment method: December 31, 2019 2018 2017 (in millions) Beginning balance $ 20 $ 22 $ 25 Charge-offs — (2 ) (3 ) Ending balance $ 20 $ 20 $ 22 Individually evaluated for impairment $ — $ — $ — Collectively evaluated for impairment 20 20 22 The recorded investment in financing receivables by impairment method was as follows: December 31, 2019 2018 (in millions) Individually evaluated for impairment $ 15 $ 19 Collectively evaluated for impairment 3,052 2,943 Total $ 3,067 $ 2,962 As of December 31, 2019 and 2018 , the Company’s recorded investment in financing receivables individually evaluated for impairment for which there was no related allowance for loan losses was $15 million and $20 million , respectively. During the years ended December 31, 2019 , 2018 and 2017 , the Company purchased $121 million , $137 million and $156 million , respectively, and sold $43 million , $44 million and $259 million , respectively, of loans. The loans purchased consisted of syndicated loans. The loans sold during 2019 and 2018 consisted of syndicated loans. The loans sold during 2017 primarily consisted of residential mortgage loans. See below for additional discussion on the sales of these loans. Credit Quality Information Nonperforming loans were $9 million and nil as of December 31, 2019 and 2018 , respectively. All other loans were considered to be performing. Commercial Mortgage Loans The Company reviews the credit worthiness of the borrower and the performance of the underlying properties in order to determine the risk of loss on commercial mortgage loans. Based on this review, the commercial mortgage loans are assigned an internal risk rating, which management updates as necessary. Commercial mortgage loans which management has assigned its highest risk rating were less than 1% of total commercial mortgage loans as of both December 31, 2019 and 2018 . Loans with the highest risk rating represent distressed loans which the Company has identified as impaired or expects to become delinquent or enter into foreclosure within the next six months. In addition, the Company reviews the concentrations of credit risk by region and property type. Concentrations of credit risk of commercial mortgage loans by U.S. region were as follows: Loans Percentage December 31, 2019 December 31, December 31, 2019 December 31, (in millions) South Atlantic $ 705 $ 699 26 % 27 % Pacific 792 766 30 30 Mountain 237 224 9 9 West North Central 207 203 8 8 East North Central 232 208 9 8 Middle Atlantic 167 171 6 7 West South Central 169 139 6 5 New England 47 54 2 2 East South Central 116 99 4 4 2,672 2,563 100 % 100 % Less: allowance for loan losses 17 16 Total $ 2,655 $ 2,547 Concentrations of credit risk of commercial mortgage loans by property type were as follows: Loans Percentage December 31, 2019 December 31, December 31, 2019 December 31, (in millions) Retail $ 891 $ 854 33 % 33 % Office 404 408 15 16 Apartments 660 583 25 23 Industrial 404 423 15 16 Mixed use 66 45 3 2 Hotel 51 43 2 2 Other 196 207 7 8 2,672 2,563 100 % 100 % Less: allowance for loan losses 17 16 Total $ 2,655 $ 2,547 Residential Mortgage Loans During the year ended December 31, 2017, the Company sold $249 million of residential mortgage loans and recorded a loss of $4 million . Syndicated Loans The recorded investment in syndicated loans as of December 31, 2019 and 2018 was $395 million and $399 million , respectively. The Company’s syndicated loan portfolio is diversified across industries and issuers. The primary credit indicator for syndicated loans is whether the loans are performing in accordance with the contractual terms of the syndication. Total nonperforming syndicated loans as of December 31, 2019 and 2018 were $9 million and nil , respectively. Troubled Debt Restructurings The recorded investment in restructured loans was not material as of both December 31, 2019 and 2018 . Troubled debt restructurings did not have a material impact to the Company’s allowance for loan losses or income recognized for the years ended December 31, 2019 , 2018 and 2017 . There are no commitments to lend additional funds to borrowers whose loans have been restructured. Deposit Receivable The deposit receivable was $1.5 billion as of December 31, 2019 . In the first quarter of 2019 , the Company reinsured approximately $1.7 billion of fixed annuity polices sold through third parties, which is approximately 20% of in force fixed annuity account balances. The arrangement contains investment guidelines and a trust to meet the Company’s risk management objectives. The transaction was effective as of January 1, 2019

Deferred Charges, Insurers [Abstract]
Deferred Acquisition Costs and Deferred Sales Inducement Costs [Text Block]	Deferred Acquisition Costs and Deferred Sales Inducement Costs In the third quarter of the year, management updates market-related inputs and implements model changes related to the living benefit valuation. In addition, management conducts its annual review of life insurance and annuity valuation assumptions relative to current experience and management expectations including modeling changes. These aforementioned changes are collectively referred to as unlocking. The impact of unlocking to DAC for the year ended December 31, 2019 primarily reflected updates to interest rate assumptions, partially offset by a favorable impact from lower surrenders on annuity contracts with a withdrawal benefit. The impact of unlocking to DAC for the year ended December 31, 2018 primarily reflected updated mortality assumptions on UL and VUL insurance products and lower surrender rate assumptions on variable annuities, partially offset by an unfavorable impact from updates to assumptions on utilization of guaranteed withdrawal benefits. The impact of unlocking to DAC for the year ended December 31, 2017 primarily reflected improved persistency and mortality on UL and VUL insurance products and a correction related to a variable annuity model assumption partially offset by updates to market-related inputs to the living benefit valuation. The balances of and changes in DAC were as follows: 2019 2018 2017 (in millions) Balance at January 1 $ 2,742 $ 2,639 $ 2,611 Capitalization of acquisition costs 239 254 242 Amortization, excluding the impact of valuation assumptions review (119 ) (288 ) (219 ) Amortization, impact of valuation assumptions review (14 ) 33 12 Impact of change in net unrealized (gains) losses on securities (175 ) 104 (7 ) Balance at December 31 $ 2,673 $ 2,742 $ 2,639 The balances of and changes in DSIC, which is included in other assets, were as follows: 2019 2018 2017 (in millions) Balance at January 1 $ 249 $ 273 $ 301 Capitalization of sales inducement costs 1 2 4 Amortization, excluding the impact of valuation assumptions review (15 ) (42 ) (37 ) Amortization, impact of valuation assumptions review — — (1 ) Impact of change in net unrealized (gains) losses on securities (19 ) 16 6 Balance at December 31 $ 216 $ 249 $ 273

Reinsurance

Reinsurance Disclosures [Abstract]
Reinsurance [Text Block]	Reinsurance The Company reinsures a portion of the insurance risks associated with its traditional life, DI and LTC insurance products through reinsurance agreements with unaffiliated reinsurance companies. Reinsurance contracts do not relieve the Company from its primary obligation to policyholders. The Company generally reinsures 90% of the death benefit liability for new term life insurance policies beginning in 2001 (RiverSource Life of NY began in 2002) and new individual UL and VUL insurance policies beginning in 2002 (2003 for RiverSource Life of NY). Policies issued prior to these dates are not subject to these same reinsurance levels. However , for IUL policies issued after September 1, 2013 and VUL policies issued after January 1, 2014, the Company generally reinsures 50% of the death benefit liability. Similarly, the Company reinsures 50% of the death benefit and morbidity liabilities related to its UL product with LTC benefits. The maximum amount of life insurance risk the Company will retain is $10 million on a single life and $10 million on any flexible premium survivorship life policy; however, reinsurance agreements are in place such that retaining more than $1.5 million of insurance risk on a single life or a flexible premium survivorship life policy is very unusual. Risk on UL and VUL policies is reinsured on a yearly renewable term basis. Risk on most term life policies starting in 2001 (2002 for RiverSource Life of NY) is reinsured on a coinsurance basis, a type of reinsurance in which the reinsurer participates proportionally in all material risks and premiums associated with a policy. The Company also has life insurance and fixed annuity risk previously assumed under reinsurance arrangements with unaffiliated insurance companies. For existing LTC policies, the Company has continued ceding 50% of the risk on a coinsurance basis to subsidiaries of Genworth Financial, Inc. (“Genworth”) and retains the remaining risk. For RiverSource Life of NY, this reinsurance arrangement applies for 1996 and later issues only. Under these agreements, the Company has the right, but never the obligation, to recapture some, or all, of the risk ceded to Genworth. Generally , the Company retains at most $5,000 per month of risk per life on DI policies sold on policy forms introduced in most states starting in 2007 (2010 for RiverSource Life of NY) and reinsures the remainder of the risk on a coinsurance basis with unaffiliated reinsurance companies. The Company retains all risk for new claims on DI contracts sold on other policy forms introduced prior to 2007 (2010 for RiverSource Life of NY). The Company also retains all risk on accidental death benefit claims and substantially all risk associated with waiver of premium provisions. As of both December 31, 2019 and 2018 , traditional life and UL insurance policies in force were $195.1 billion , of which $142.8 billion and $142.4 billion as of December 31, 2019 and 2018 were reinsured at the respective year ends. The effect of reinsurance on premiums for traditional long-duration products was as follows: Years Ended December 31, 2019 2018 2017 (in millions) Direct premiums $ 621 $ 621 $ 637 Reinsurance ceded (224 ) (225 ) (227 ) Net premiums $ 397 $ 396 $ 410 Policy and contract charges are presented on the Consolidated Statements of Income net of $132 million , $126 million and $114 million of reinsurance ceded for non-traditional long-duration products for the years ended December 31, 2019 , 2018 and 2017 , respectively. The amount of claims recovered through reinsurance on all contracts was $377 million , $331 million and $298 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Reinsurance recoverables include approximately $2.5 billion related to LTC risk ceded to Genworth as of both December 31, 2019 and 2018 . Policyholder account balances, future policy benefits and claims include $466 million and $484 million related to previously assumed reinsurance arrangements as of December 31, 2019 and 2018 , respectively.

(2) Includes the fair value of GMAB embedded derivatives that was a net asset as of both December 31, 2019 and 2018 reported as a contra liability. Fixed Annuities Fixed annuities include deferred, payout and indexed annuity contracts. Deferred contracts offer a guaranteed minimum rate of interest and security of the principal invested. Payout contracts guarantee a fixed income payment for life or the term of the contract. Liabilities for fixed annuities in a benefit or payout status are based on future estimated payments using established industry mortality tables and interest rates, ranging from 2.71% to 9.38% as of December 31, 2019 , depending on year of issue, with an average rate of approximately 3.83% . The Company generally invests the proceeds from the annuity contracts in fixed rate securities. The Company’s equity indexed annuity (“EIA”) product is a single premium fixed deferred annuity. The Company discontinued new sales of EIAs in 2007. The contract was issued with an initial term of seven years and interest earnings are linked to the performance of the S&P 500 ® Index. This annuity has a minimum interest rate guarantee of 3% on 90% of the initial premium, adjusted for any surrenders. The Company generally invests the proceeds from the annuity contracts in fixed rate securities and hedges the equity risk with derivative instruments. The Company’s fixed index annuity product is a fixed annuity that includes an indexed account. The rate of interest credited above the minimum guarantee for funds allocated to the indexed account is linked to the performance of the specific index for the indexed account (subject to a cap). The Company offers S&P 500 ® Index and MSCI ® EAFE Index account options. Both options offer two crediting durations, one-year and two-year. The contractholder may allocate all or a portion of the policy value to a fixed or indexed account. The portion of the policy allocated to the indexed account is accounted for as an embedded derivative. The Company hedges the interest credited rate including equity and interest rate risk related to the indexed account with derivative instruments. The contractholder can choose to add a GMWB for life rider for an additional fee. See Note 17 for additional information regarding the Company’s derivative instruments used to hedge the risk related to indexed annuities. Variable Annuities Purchasers of variable annuities can select from a variety of investment options and can elect to allocate a portion to a fixed account. A vast majority of the premiums received for variable annuity contracts are held in separate accounts where the assets are held for the exclusive benefit of those contractholders. Most of the variable annuity contracts currently issued by the Company contain one or more guaranteed benefits, including GMWB, GMAB, GMDB and GGU provisions. The Company previously offered contracts with GMIB provisions. See Notes 2 and 11 for additional information regarding the Company’s variable annuity guarantees. The Company does not currently hedge its risk under the GGU and GMIB provisions. See Notes 13 and 17 for additional information regarding the Company’s derivative instruments used to hedge risks related to GMWB, GMAB and GMDB provisions. Insurance Liabilities UL/VUL is the largest group of insurance policies written by the Company. Purchasers of UL accumulate cash value that increases by a fixed interest rate. Purchasers of VUL can select from a variety of investment options and can elect to allocate a portion to a fixed account or a separate account. A vast majority of the premiums received for VUL policies are held in separate accounts where the assets are held for the exclusive benefit of those policyholders. IUL is a UL policy that includes an indexed account. The rate of credited interest above the minimum guarantee for funds allocated to the indexed account is linked to the performance of the specific index for the indexed account (subject to a cap and floor). The Company offers an S&P 500 ® Index account option and a blended multi-index account option comprised of the S&P 500 Index, the MSCI ® EAFE Index and the MSCI EM Index. Both options offer two crediting durations, one-year and two-year. The policyholder may allocate all or a portion of the policy value to a fixed or any available indexed account. The portion of the policy allocated to the indexed account is accounted for as an embedded derivative at fair value. The Company hedges the interest credited rate including equity and interest rate risk related to the indexed account with derivative instruments. See Note 17 for additional information regarding the Company’s derivative instruments used to hedge the risk related to IUL. The Company also offers term life insurance as well as DI products. The Company no longer offers standalone LTC products and whole life insurance but has in force policies from prior years. Insurance liabilities include accumulation values, incurred but not reported claims, obligations for anticipated future claims and unpaid reported claims. The liability for estimates of benefits that will become payable on future claims on term life, whole life and DI policies is based on the net level premium and LTC policies is based on a gross premium valuation reflecting management’s current best estimate assumptions. Both include the anticipated interest rates earned on assets supporting the liability. Anticipated interest rates for term and whole life ranged from 3% to 10% as of December 31, 2019 . Anticipated interest rates for DI policies ranged from 3.5% to 7.5% as of December 31, 2019 and for LTC policies ranged from 5.8% to 6.8% as of December 31, 2019 . The liability for unpaid reported claims on DI and LTC policies includes an estimate of the present value of obligations for continuing benefit payments. The discount rates used to calculate present values are based on average interest rates earned on assets supporting the liability for unpaid amounts and were 4.5% and 6.0% for DI and LTC claims, respectively, as of December 31, 2019 . Portions of the Company’s UL and VUL policies have product features that result in profits followed by losses from the insurance component of the policy. These profits followed by losses can be generated by the cost structure of the product or secondary guarantees in the policy. The secondary guarantee ensures that, subject to specified conditions, the policy will not terminate and will continue to provide a death benefit even if there is insufficient policy value to cover the monthly deductions and charges. Separate Account Liabilities Separate account liabilities consisted of the following: December 31, 2019 2018 (in millions) Variable annuity $ 74,965 $ 66,913 VUL insurance 7,429 6,451 Other insurance 31 29 Total $ 82,425 $ 73,393

Insurance [Abstract]
Variable Annuity and Insurance Guarantees [Text Block]	Variable Annuity and Insurance Guarantees The majority of the variable annuity contracts offered by the Company contain GMDB provisions. The Company also offers variable annuities with GGU, GMWB and GMAB provisions. The Company previously offered contracts containing GMIB provisions. See Notes 2 and 10 for additional information regarding the Company’s variable annuity guarantees. The GMDB and GGU provisions provide a specified minimum return upon death of the contractholder. The death benefit payable is the greater of (i) the contract value less any purchase payment credits subject to recapture less a pro-rata portion of any rider fees, or (ii) the GMDB provisions specified in the contract. The Company has the following primary GMDB provisions: • Return of premium – provides purchase payments minus adjusted partial surrenders. • Reset – provides that the value resets to the account value every sixth contract anniversary minus adjusted partial surrenders. This provision was often provided in combination with the return of premium provision and is no longer offered. • Ratchet – provides that the value ratchets up to the maximum account value at specified anniversary intervals, plus subsequent purchase payments less adjusted partial surrenders. The variable annuity contracts with GMWB riders typically have account values that are based on an underlying portfolio of mutual funds, the values of which fluctuate based on fund performance. At issue the guaranteed amount is equal to the amount deposited but the guarantee may be increased annually to the account value (a “step-up”) in the case of favorable market performance or by a benefit credit if the contract includes this provision. The Company has GMWB riders in force, which contain one or more of the following provisions: • Withdrawals at a specified rate per year until the amount withdrawn is equal to the guaranteed amount. • Withdrawals at a specified rate per year for the life of the contractholder (“GMWB for life”). • Withdrawals at a specified rate per year for joint contractholders while either is alive. • Withdrawals based on performance of the contract. • Withdrawals based on the age withdrawals begin. • Credits are applied annually for a specified number of years to increase the guaranteed amount as long as withdrawals have not been taken. Variable annuity contractholders age 79 or younger at contract issue can also obtain a principal-back guarantee by purchasing the optional GMAB rider for an additional charge. The GMAB rider guarantees that, regardless of market performance at the end of the 10 -year waiting period, the contract value will be no less than the original investment or a specified percentage of the highest anniversary value, adjusted for withdrawals. If the contract value is less than the guarantee at the end of the 10 -year period, a lump sum will be added to the contract value to make the contract value equal to the guarantee value. Certain UL policies offered by the Company provide secondary guarantee benefits. The secondary guarantee ensures that, subject to specified conditions, the policy will not terminate and will continue to provide a death benefit even if there is insufficient policy value to cover the monthly deductions and charges. The following table provides information related to variable annuity guarantees for which the Company has established additional liabilities: Variable Annuity Guarantees by Benefit Type (1) December 31, 2019 December 31, 2018 Total Contract Net Weighted Average Attained Age Total Contract Net Weighted Average Attained Age (in millions, except age) GMDB: Return of premium $ 62,909 $ 60,967 $ 5 67 $ 55,810 $ 53,872 $ 417 67 Five/six-year reset 7,983 5,263 7 67 7,670 4,941 112 67 One-year ratchet 5,935 5,600 7 70 5,560 5,210 417 70 Five-year ratchet 1,396 1,340 — 66 1,307 1,251 23 66 Other 1,192 1,174 65 73 1,033 1,014 148 72 Total — GMDB $ 79,415 $ 74,344 $ 84 67 $ 71,380 $ 66,288 $ 1,117 67 GGU death benefit $ 1,115 $ 1,063 $ 133 71 $ 992 $ 940 $ 112 70 GMIB $ 186 $ 172 $ 6 70 $ 180 $ 164 $ 12 69 GMWB: GMWB $ 1,999 $ 1,993 $ 1 73 $ 1,990 $ 1,984 $ 3 72 GMWB for life 46,799 46,691 272 68 40,966 40,876 742 68 Total — GMWB $ 48,798 $ 48,684 $ 273 68 $ 42,956 $ 42,860 $ 745 68 GMAB $ 2,528 $ 2,524 $ — 60 $ 2,456 $ 2,450 $ 24 59 (1) Individual variable annuity contracts may have more than one guarantee and therefore may be included in more than one benefit type. Variable annuity contracts for which the death benefit equals the account value are not shown in this table. The net amount at risk for GMDB, GGU and GMAB is defined as the current guaranteed benefit amount in excess of the current contract value. The net amount at risk for GMIB is defined as the greater of the present value of the minimum guaranteed annuity payments less the current contract value or zero. The net amount at risk for GMWB is defined as the greater of the present value of the minimum guaranteed withdrawal payments less the current contract value or zero.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; that is, an exit price. The exit price assumes the asset or liability is not exchanged subject to a forced liquidation or distressed sale. Valuation Hierarchy The Company categorizes its fair value measurements according to a three-level hierarchy. The hierarchy prioritizes the inputs used by the Company’s valuation techniques. A level is assigned to each fair value measurement based on the lowest level input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are defined as follows: Level 1 Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date. Level 2 Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities. Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. The following tables present the balances of assets and liabilities measured at fair value on a recurring basis: December 31, 2019 Level 1 Level 2 Level 3 Total (in millions) Assets Available-for-Sale securities: Corporate debt securities $ — $ 10,787 $ 735 $ 11,522 Residential mortgage backed securities — 3,091 17 3,108 Commercial mortgage backed securities — 3,618 — 3,618 State and municipal obligations — 1,306 — 1,306 Asset backed securities — 691 389 1,080 Foreign government bonds and obligations — 267 — 267 U.S. government and agency obligations 1 — — 1 Total Available-for-Sale securities: 1 19,760 1,141 20,902 Cash equivalents — 1,256 — 1,256 Other assets: Interest rate derivative contracts — 1,451 — 1,451 Equity derivative contracts 162 2,650 — 2,812 Foreign exchange derivative contracts 1 15 — 16 Credit derivative contracts — 4 — 4 Total other assets 163 4,120 — 4,283 Separate account assets at net asset value (“NAV”) 82,425 (1) Total assets at fair value $ 164 $ 25,136 $ 1,141 $ 108,866 Liabilities Policyholder account balances, future policy benefits and claims: Indexed annuity embedded derivatives $ — $ 3 $ 43 $ 46 IUL embedded derivatives — — 881 881 GMWB and GMAB embedded derivatives — — 763 763 (2) Total policyholder account balances, future policy benefits and claims — 3 1,687 1,690 (3) Other liabilities: Interest rate derivative contracts — 418 — 418 Equity derivative contracts 36 3,018 — 3,054 Foreign exchange derivative contracts 1 5 — 6 Total other liabilities 37 3,441 — 3,478 Total liabilities at fair value $ 37 $ 3,444 $ 1,687 $ 5,168 December 31, 2018 Level 1 Level 2 Level 3 Total (in millions) Assets Available-for-Sale securities: Corporate debt securities $ — $ 11,520 $ 871 $ 12,391 Residential mortgage backed securities — 2,807 64 2,871 Commercial mortgage backed securities — 3,652 — 3,652 State and municipal obligations — 1,283 — 1,283 Asset backed securities — 671 374 1,045 Foreign government bonds and obligations — 285 — 285 U.S. government and agency obligations 1 — — 1 Total Available-for-Sale securities: 1 20,218 1,309 21,528 Cash equivalents — 1,000 — 1,000 Other assets: Interest rate derivative contracts — 789 — 789 Equity derivative contracts 189 1,515 — 1,704 Foreign exchange derivative contracts — 54 — 54 Total other assets 189 2,358 — 2,547 Separate account assets at NAV 73,393 (1) Total assets at fair value $ 190 $ 23,576 $ 1,309 $ 98,468 Liabilities Policyholder account balances, future policy benefits and claims: Indexed annuity embedded derivatives $ — $ 3 $ 14 $ 17 IUL embedded derivatives — — 628 628 GMWB and GMAB embedded derivatives — — 328 328 (4) Total policyholder account balances, future policy benefits and claims — 3 970 973 (5) Other liabilities: Interest rate derivative contracts — 422 — 422 Equity derivative contracts 77 1,901 — 1,978 Foreign exchange derivative contracts 2 32 — 34 Credit derivative contracts — 18 — 18 Total other liabilities 79 2,373 — 2,452 Total liabilities at fair value $ 79 $ 2,376 $ 970 $ 3,425 (1) Amounts are comprised of certain financial instruments that are measured at fair value using the NAV per share (or its equivalent) as a practical expedient and have not been classified in the fair value hierarchy.

Securities transferred from Level 3 primarily represent securities with fair values that are now obtained from a third-party pricing service with observable inputs. Securities transferred to Level 3 represent securities with fair values that are now based on a single non-binding broker quote. The following tables provide a summary of the significant unobservable inputs used in the fair value measurements developed by the Company or reasonably available to the Company of Level 3 assets and liabilities: December 31, 2019 Fair Value Valuation Technique Unobservable Input Range Weighted Average (in millions) Corporate debt securities $ 735 Discounted cash flow Yield/spread to U.S. Treasuries 0.8% - 2.8% 1.3 % Asset backed securities $ 389 Discounted cash flow Annual default rate 3.5% Loss severity 25.0% Yield/spread to swap rates 120 bps - 170 bps 123 bps IUL embedded derivatives $ 881 Discounted cash flow Nonperformance risk (1) 65 bps Indexed annuity embedded derivatives $ 43 Discounted cash flow Surrender rate 0.0% - 50.0% Nonperformance risk (1) 65 bps GMWB and GMAB embedded derivatives $ 763 Discounted cash flow Utilization of guaranteed withdrawals (2) 0.0% - 36.0% Surrender rate 0.1% - 73.5% Market volatility (3) 3.7% - 15.9% Nonperformance risk (1) 65 bps December 31, 2018 Fair Value Valuation Technique Unobservable Input Range Weighted Average (in millions) Corporate debt securities (private placements) $ 871 Discounted cash flow Yield/spread to U.S. Treasuries 1.0 % - 3.6% 1.5 % Asset backed securities $ 374 Discounted cash flow Annual default rate 2.5% Loss severity 25.0% Yield/spread to swap rates 85 bps - 115 bps 87 bps IUL embedded derivatives $ 628 Discounted cash flow Nonperformance risk (1) 119 bps Indexed annuity embedded derivatives $ 14 Discounted cash flow Surrender rate 0.0% - 50.0% Nonperformance risk (1) 119 bps GMWB and GMAB embedded derivatives $ 328 Discounted cash flow Utilization of guaranteed withdrawals (2) 0.0 % - 36.0% Surrender rate 0.1 % - 73.4% Market volatility (3) 4.0 % - 16.1% Nonperformance risk (1) 119 bps (1) The nonperformance risk is the spread added to the observable interest rates used in the valuation of the embedded derivatives. (2) The utilization of guaranteed withdrawals represents the percentage of contractholders that will begin withdrawing in any given year. (3) Market volatility is implied volatility of fund of funds and managed volatility funds. Level 3 measurements not included in the table above are obtained from non-binding broker quotes where unobservable inputs utilized in the fair value calculation are not reasonably available to the Company. Uncertainty of Fair Value Measurements Significant increases (decreases) in the yield/spread to U.S. Treasuries used in the fair value measurement of Level 3 corporate debt securities in isolation would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the annual default rate used in the fair value measurement of Level 3 asset backed securities in isolation, generally, would have resulted in a significantly lower (higher) fair value measurement and significant increases (decreases) in loss severity in isolation would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the yield/spread to swap rates in isolation would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in nonperformance risk used in the fair value measurement of the IUL embedded derivatives in isolation would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in nonperformance risk and surrender rate used in the fair value measurement of the indexed annuity embedded derivatives in isolation would have resulted in a significantly lower (higher) liability value. Significant increases (decreases) in utilization and volatility used in the fair value measurement of the GMWB and GMAB embedded derivatives in isolation would have resulted in a significantly higher (lower) liability value. Significant increases (decreases) in nonperformance risk and surrender rate used in the fair value measurement of the GMWB and GMAB embedded derivatives in isolation would have resulted in a significantly lower (higher) liability value. Utilization of guaranteed withdrawals and surrender rates vary with the type of rider, the duration of the policy, the age of the contractholder, the distribution channel and whether the value of the guaranteed benefit exceeds the contract accumulation value. Determination of Fair Value The Company uses valuation techniques consistent with the market and income approaches to measure the fair value of its assets and liabilities. The Company’s market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Company’s income approach uses valuation techniques to convert future projected cash flows to a single discounted present value amount. When applying either approach, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. The following is a description of the valuation techniques used to measure fair value and the general classification of these instruments pursuant to the fair value hierarchy. Assets Cash Equivalents Cash equivalents include highly liquid investments with original or remaining maturities at the time of purchase of 90 days or less. The Company’s cash equivalents are classified as Level 2 and measured at amortized cost, which is a reasonable estimate of fair value because of the short time between the purchase of the instrument and its expected realization. Available-for-Sale Securities When available, the fair value of securities is based on quoted prices in active markets. If quoted prices are not available, fair values are obtained from third-party pricing services, non-binding broker quotes, or other model-based valuation techniques. Level 1 securities primarily include U.S. Treasuries. Level 2 securities primarily include corporate bonds, residential mortgage backed securities, commercial mortgage backed securities, state and municipal obligations, asset backed securities and foreign government securities. The fair value of these Level 2 securities is based on a market approach with prices obtained from third-party pricing services. Observable inputs used to value these securities can include, but are not limited to, reported trades, benchmark yields, issuer spreads and non-binding broker quotes. Level 3 securities primarily include certain corporate bonds, non-agency residential mortgage backed securities and affiliated and unaffiliated asset backed securities. The fair value of corporate bonds, non-agency residential mortgage backed securities and unaffiliated asset backed securities classified as Level 3 is typically based on a single non-binding broker quote. The underlying inputs used for some of the non-binding broker quotes are not readily available to the Company. The Company’s privately placed corporate bonds are typically based on a single non-binding broker quote. The fair value of affiliated asset backed securities is determined using a discounted cash flow model. Inputs used to determine the expected cash flows include assumptions about discount rates and default, prepayment and recovery rates of the underlying assets. Given the significance of the unobservable inputs to this fair value measurement, the fair value of the investment in the affiliated asset backed securities is classified as Level 3. In consideration of the above, management is responsible for the fair values recorded on the financial statements. Prices received from third-party pricing services are subjected to exception reporting that identifies investments with significant daily price movements as well as no movements. The Company reviews the exception reporting and resolves the exceptions through reaffirmation of the price or recording an appropriate fair value estimate. The Company also performs subsequent transaction testing. The Company performs annual due diligence of third-party pricing services. The Company’s due diligence procedures include assessing the vendor’s valuation qualifications, control environment, analysis of asset-class specific valuation methodologies, and understanding of sources of market observable assumptions and unobservable assumptions, if any, employed in the valuation methodology. The Company also considers the results of its exception reporting controls and any resulting price challenges that arise. Separate Account Assets The fair value of assets held by separate accounts is determined by the NAV of the funds in which those separate accounts are invested. The NAV is used as a practical expedient for fair value and represents the exit price for the separate account. Separate account assets are excluded from classification in the fair value hierarchy. Other Assets Derivatives that are measured using quoted prices in active markets, such as derivatives that are exchange-traded, are classified as Level 1 measurements. The variation margin on futures contracts is also classified as Level 1. The fair value of derivatives that are traded in less active over-the-counter (“OTC”) markets is generally measured using pricing models with market observable inputs such as interest rates and equity index levels. These measurements are classified as Level 2 within the fair value hierarchy and include swaps and the majority of options. The counterparties’ nonperformance risk associated with uncollateralized derivative assets was immaterial as of December 31, 2019 and 2018 . See Notes 16 and 17 for further information on the credit risk of derivative instruments and related collateral. Liabilities Policyholder Account Balances, Future Policy Benefits and Claims There is no active market for the transfer of the Company’s embedded derivatives attributable to the provisions of certain variable annuity riders, index annuity and IUL products. The Company values the embedded derivatives attributable to the provisions of certain variable annuity riders using internal valuation models. These models calculate fair value as the present value of future expected benefit payments less the present value of future expected rider fees attributable to the embedded derivative feature. The projected cash flows used by these models include observable capital market assumptions and incorporate significant unobservable inputs related to implied volatility as well as contractholder behavior assumptions that include margins for risk, all of which the Company believes an exit market participant would expect. The fair value also reflects a current estimate of the Company’s nonperformance risk specific to these embedded derivatives. Given the significant unobservable inputs to this valuation, these measurements are classified as Level 3. The embedded derivatives attributable to these provisions are recorded in policyholder account balances, future policy benefits and claims. The Company uses various Black-Scholes calculations to determine the fair value of the embedded derivatives associated with the provisions of its fixed index annuity and IUL products. The Company uses a discounted cash flow model to determine the fair value of the embedded derivatives associated with the provisions of its equity index annuity product. The projected cash flows generated by this model are based on significant observable inputs related to interest rates, volatilities and equity index levels and, therefore, are classified as Level 2. The fair value of fixed index annuity and IUL embedded derivatives includes significant observable interest rates, volatilities and equity index levels and the significant unobservable estimate of the Company’s nonperformance risk. Given the significance of the nonperformance risk assumption to the fair value, the fixed index annuity and IUL embedded derivatives are classified as Level 3. The embedded derivatives attributable to these provisions are recorded in policyholder account balances, future policy benefits and claims. Other Liabilities Derivatives that are measured using quoted prices in active markets, such as derivatives that are exchange-traded, are classified as Level 1 measurements. The variation margin on futures contracts is also classified as Level 1. The fair value of derivatives that are traded in less active OTC markets is generally measured using pricing models with market observable inputs such as interest rates and equity index levels. These measurements are classified as Level 2 within the fair value hierarchy and include swaps and the majority of options. The Company’s nonperformance risk associated with uncollateralized derivative liabilities was immaterial as of December 31, 2019 and 2018 . See Notes 16 and 17 for further information on the credit risk of derivative instruments and related collateral. Fair Value on a Nonrecurring Basis The Company assesses its investment in affordable housing partnerships for OTTI. The investments that are determined to be OTTI are written down to their fair value. The Company uses a discounted cash flow model to measure the fair value of these investments. Inputs to the discounted cash flow model are estimates of future net operating losses and tax credits available to the Company and discount rates based on market condition and the financial strength of the syndicator (general partner).

Insurance [Abstract]
Regulatory Requirements [Text Block]	Regulatory Requirements 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. The Company has met its minimum RBC requirements. 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 Insurance Company 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. The permitted practice allowed RiverSource Life Insurance Company 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 Insurance Company 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 and other distributions that insurers may make without providing prior notification to state regulators. For RiverSource Life Insurance Company, 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 Insurance Company’s primary regulator, and are subject to potential disapproval. RiverSource Life Insurance Company’s statutory unassigned surplus aggregated $326 million and $642 million as of December 31, 2019 and 2018 , respectively. In addition, dividends or distributions whose fair market value, together with that of other dividends or distributions 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 was $2.9 billion and $3.3 billion as of December 31, 2019 and 2018 , respectively. Statutory net gain from operations and net income (loss) for RiverSource Life Insurance Company are summarized as follows: Years Ended December 31, 2019 2018 2017 (in millions) Statutory net gain from operations $ 1,505 $ 1,686 $ 958 Statutory net income (loss) 786 1,628 222 Government debt securities of $4 million as of both December 31, 2019 and 2018

Offsetting [Abstract]
Offsetting Assets and Liabilities [Text Block]	Offsetting Assets and Liabilities Certain financial instruments and derivative instruments are eligible for offset in the Consolidated Balance Sheets. The Company’s derivative instruments and repurchase agreements are subject to master netting and collateral arrangements and qualify for offset. A master netting arrangement with a counterparty creates a right of offset for amounts due to and from that same counterparty that is enforceable in the event of a default or bankruptcy. The Company’s policy is to recognize amounts subject to master netting arrangements on a gross basis in the Consolidated Balance Sheets. The following tables present the gross and net information about the Company’s assets subject to master netting arrangements: December 31, 2019 Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Amounts of Assets Presented in the Consolidated Balance Sheets Gross Amounts Not Offset in the Consolidated Balance Sheets Net Amount Financial Instruments (1) Cash Collateral Securities Collateral (in millions) Derivatives: OTC $ 4,181 $ — $ 4,181 $ (2,886 ) $ (1,214 ) $ (73 ) $ 8 OTC cleared 21 — 21 (21 ) — — — Exchange-traded 81 — 81 (5 ) — — 76 Total derivatives $ 4,283 $ — $ 4,283 $ (2,912 ) $ (1,214 ) $ (73 ) $ 84 December 31, 2018 Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Amounts of Assets Presented in the Consolidated Balance Sheets Gross Amounts Not Offset in the Consolidated Balance Sheets Net Amount Financial Instruments (1) Cash Collateral Securities Collateral (in millions) Derivatives: OTC $ 2,499 $ — $ 2,499 $ (2,066 ) $ (390 ) $ (26 ) $ 17 OTC cleared 34 — 34 (23 ) — — 11 Exchange-traded 14 — 14 (1 ) — — 13 Total derivatives $ 2,547 $ — $ 2,547 $ (2,090 ) $ (390 ) $ (26 ) $ 41 (1) Represents the amount of assets that could be offset by liabilities with the same counterparty under master netting or similar arrangements that management elects not to offset on the Consolidated Balance Sheets. The following tables present the gross and net information about the Company’s liabilities subject to master netting arrangements: December 31, 2019 Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheets Amounts of Liabilities Presented in the Consolidated Balance Sheets Gross Amounts Not Offset in the Consolidated Balance Sheets Net Amount Financial Instruments (1) Cash Collateral Securities Collateral (in millions) Derivatives: OTC $ 3,426 $ — $ 3,426 $ (2,886 ) $ — $ (540 ) $ — OTC cleared 41 — 41 (21 ) — — 20 Exchange-traded 11 — 11 (5 ) — — 6 Total derivatives $ 3,478 $ — $ 3,478 $ (2,912 ) $ — $ (540 ) $ 26 December 31, 2018 Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheets Amounts of Liabilities Presented in the Consolidated Balance Sheets Gross Amounts Not Offset in the Consolidated Balance Sheets Net Amount Financial Instruments (1) Cash Collateral Securities Collateral (in millions) Derivatives: OTC $ 2,419 $ — $ 2,419 $ (2,066 ) $ (24 ) $ (328 ) $ 1 OTC cleared 23 — 23 (23 ) — — — Exchange-traded 10 — 10 (1 ) — — 9 Total derivatives 2,452 — 2,452 (2,090 ) (24 ) (328 ) 10 Repurchase agreements 50 — 50 — — (50 ) — Total $ 2,502 $ — $ 2,502 $ (2,090 ) $ (24 ) $ (378 ) $ 10 ( 1) Represents the amount of liabilities that could be offset by assets with the same counterparty under master netting or similar arrangements that management elects not to offset on the Consolidated Balance Sheets. In the tables above, the amount of assets or liabilities presented are offset first by financial instruments that have the right of offset under master netting or similar arrangements, then any remaining amount is reduced by the amount of cash and securities collateral. The actual collateral may be greater than amounts presented in the tables. When the fair value of collateral accepted by the Company is less than the amount due to the Company, there is a risk of loss if the counterparty fails to perform or provide additional collateral. To mitigate this risk, the Company monitors collateral values regularly and requires additional collateral when necessary. When the value of collateral pledged by the Company declines, it may be required to post additional collateral. Freestanding derivative instruments are reflected in other assets and other liabilities. Cash collateral pledged by the Company is reflected in other assets and cash collateral accepted by the Company is reflected in other liabilities. Repurchase agreements are reflected in short-term borrowings. See Note 17 for additional disclosures related to the Company’s derivative instruments and Note 12 for additional disclosures related to the Company’s repurchase agreements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities [Text Block]	Derivatives and Hedging Activities Derivative instruments enable the Company to manage its exposure to various market risks. The value of such instruments is derived from an underlying variable or multiple variables, including equity and interest rate indices or prices. The Company primarily enters into derivative agreements for risk management purposes related to the Company’s products and operations. Certain of the Company’s freestanding derivative instruments are subject to master netting arrangements. The Company’s policy on the recognition of derivatives on the Consolidated Balance Sheets is to not offset fair value amounts recognized for derivatives and collateral arrangements executed with the same counterparty under the same master netting arrangement. See Note 16 for additional information regarding the estimated fair value of the Company’s freestanding derivatives after considering the effect of master netting arrangements and collateral. The Company uses derivatives as economic hedges and accounting hedges. The following table presents the notional value and gross fair value of derivative instruments, including embedded derivatives: December 31, 2019 December 31, 2018 Notional Gross Fair Value Notional Gross Fair Value Assets (1) Liabilities (2) Assets (1) Liabilities (2) (in millions) Derivatives not designated as hedging instruments Interest rate contracts $ 57,950 $ 1,451 $ 418 $ 57,185 $ 789 $ 422 Equity contracts 60,596 2,812 3,054 51,463 1,704 1,978 Credit contracts 1,386 4 — 1,206 — 18 Foreign exchange contracts 3,251 16 6 4,747 54 34 Total non-designated hedges 123,183 4,283 3,478 114,601 2,547 2,452 Embedded derivatives GMWB and GMAB (3) N/A — 763 N/A — 328 IUL N/A — 881 N/A — 628 Indexed annuities N/A — 46 N/A — 17 Total embedded derivatives N/A — 1,690 N/A — 973 Total derivatives $ 123,183 $ 4,283 $ 5,168 $ 114,601 $ 2,547 $ 3,425 N/A Not applicable. (1) The fair value of freestanding derivative assets is included in Other assets on the Consolidated Balance Sheets. (2) The fair value of freestanding derivative liabilities is included in Other liabilities on the Consolidated Balance Sheets. The fair value of GMWB and GMAB, IUL, and indexed annuity embedded derivatives is included in Policyholder account balances, future policy benefits and claims on the Consolidated Balance Sheets. (3) The fair value of the GMWB and GMAB embedded derivatives as of December 31, 2019 included $981 million of individual contracts in a liability position and $218 million of individual contracts in an asset position. The fair value of the GMWB and GMAB embedded derivatives as of December 31, 2018 included $646 million of individual contracts in a liability position and $318 million of individual contracts in an asset position. See Note 13 for additional information regarding the Company’s fair value measurement of derivative instruments. As of December 31, 2019 and 2018 , investment securities with a fair value of $84 million and $28 million , respectively, were received as collateral to meet contractual obligations under derivative contracts, of which $84 million and $28 million , respectively, may be sold, pledged or rehypothecated by the Company. As of both December 31, 2019 and 2018 , the Company had sold, pledged, or rehypothecated none of these securities. In addition, as of both December 31, 2019 and 2018 , non-cash collateral accepted was held in separate custodial accounts and was not included in the Company’s Consolidated Balance Sheets. The following table presents a summary of the impact of derivatives not designated as hedging instruments, including embedded derivatives, on the Consolidated Statements of Income: Interest Credited to Fixed Accounts Benefits, Claims, Losses and Settlement Expenses (in millions) Year Ended December 31, 2019 Interest rate contracts $ — $ 1,100 Equity contracts 117 (1,501 ) Credit contracts — (73 ) Foreign exchange contracts — (30 ) GMWB and GMAB embedded derivatives — (435 ) IUL embedded derivatives (140 ) — Indexed annuities embedded derivatives (8 ) — Total gain (loss) $ (31 ) $ (939 ) Year Ended December 31, 2018 Interest rate contracts $ — $ (312 ) Equity contracts (49 ) 306 Credit contracts — 7 Foreign exchange contracts — 1 Other contracts — (4 ) GMWB and GMAB embedded derivatives — (377 ) IUL embedded derivatives 63 — Indexed annuities embedded derivatives 3 — Total gain (loss) $ 17 $ (379 ) Year Ended December 31, 2017 Interest rate contracts $ — $ 3 Equity contracts 75 (1,006 ) Credit contracts — (22 ) Foreign exchange contracts — (23 ) Other contracts — (2 ) GMWB and GMAB embedded derivatives — 663 IUL embedded derivatives (45 ) — Total gain (loss) $ 30 $ (387 ) The Company holds derivative instruments that either do not qualify or are not designated for hedge accounting treatment. These derivative instruments are used as economic hedges of equity, interest rate, credit and foreign currency exchange rate risk related to various products and transactions of the Company. Certain annuity contracts contain GMWB or GMAB provisions, which guarantee the right to make limited partial withdrawals each contract year regardless of the volatility inherent in the underlying investments or guarantee a minimum accumulation value of consideration received at the beginning of the contract period, after a specified holding period, respectively. The GMAB and non-life contingent GMWB provisions are considered embedded derivatives, which are bifurcated from their host contracts for valuation purposes and reported on the Consolidated Balance Sheets at fair value with changes in fair value reported in earnings. The Company economically hedges the exposure related to GMAB and non-life contingent GMWB provisions using options (equity index, interest rate swaptions, etc.), swaps (interest rate, total return, etc.) and futures. The deferred premium associated with certain of the above options and swaptions is paid or received semi-annually over the life of the contract or at maturity. The following is a summary of the payments the Company is scheduled to make and receive for these options and swaptions as of December 31, 2019 : Premiums Premiums (in millions) 2020 $ 214 $ 133 2021 152 112 2022 204 198 2023 126 58 2024 70 10 2025-2029 351 7 Total $ 1,117 $ 518 Actual timing and payment amounts may differ due to future settlements, modifications or exercises of the contracts prior to the full premium being paid or received. The Company has a macro hedge program to provide protection against the statutory tail scenario risk arising from variable annuity reserves on its statutory surplus and to cover some of the residual risks not covered by other hedging activities. As a means of economically hedging these risks, the Company may use a combination of futures, options, swaps and swaptions. Certain of the macro hedge derivatives may contain settlement provisions linked to both equity returns and interest rates. The Company’s macro hedge derivatives that contain settlement provisions linked to both equity returns and interest rates, if any, are shown in other contracts in the tables above. Indexed annuity and IUL products have returns tied to the performance of equity markets. As a result of fluctuations in equity markets, the obligation incurred by the Company related to indexed annuity and IUL products will positively or negatively impact earnings over the life of these products. The equity component of indexed annuity and IUL product obligations are considered embedded derivatives, which are bifurcated from their host contracts for valuation purposes and reported on the Consolidated Balance Sheets at fair value with changes in fair value reported in earnings. As a means of economically hedging its obligations under the provisions of these products, the Company enters into index options and futures contracts. Cash Flow Hedges During the year ended December 31, 2019 , the Company held no derivatives that were designated as cash flow hedges. During the years ended December 31, 2019 and 2018 , no hedge relationships were discontinued due to forecasted transactions no longer being expected to occur according to the original hedge strategy. For the years ended December 31, 2019 , 2018 and 2017 , amounts recognized in earnings on derivative transactions that were ineffective were not material. See Note 18 for a summary of net unrealized gains (losses) included in AOCI related to previously designated cash flow hedges. Credit Risk Credit risk associated with the Company’s derivatives is the risk that a derivative counterparty will not perform in accordance with the terms of the applicable derivative contract. To mitigate such risk, the Company has established guidelines and oversight of credit risk through a comprehensive enterprise risk management program that includes members of senior management. Key components of this program are to require preapproval of counterparties and the use of master netting and collateral arrangements whenever practical. See Note 16 for additional information on the Company’s credit exposure related to derivative assets. Certain of the Company’s derivative contracts contain provisions that adjust the level of collateral the Company is required to post based on the Company’s financial strength rating (or based on the debt rating of the Company’s parent, Ameriprise Financial). Additionally, certain of the Company’s derivative contracts contain provisions that allow the counterparty to terminate the contract if the Company does not maintain a specific financial strength rating or Ameriprise Financial’s debt does not maintain a specific credit rating (generally an investment grade rating). If these termination provisions were to be triggered, the Company’s counterparty could require immediate settlement of any net liability position. As of December 31, 2019 and 2018 , the aggregate fair value of derivative contracts in a net liability position containing such credit contingent provisions was $189 million and $91 million , respectively. The aggregate fair value of assets posted as collateral for such instruments as of December 31, 2019 and 2018 was $189 million and $90 million , respectively. If the credit contingent provisions of derivative contracts in a net liability position as of December 31, 2019 and 2018 were triggered, the aggregate fair value of additional assets that would be required to be posted as collateral or needed to settle the instruments immediately would have been nil and $1 million , respectively.

Income Taxes	Income Taxes The components of income tax provision were as follows: Years Ended December 31, 2019 2018 2017 (in millions) Current income tax Federal $ 210 $ 35 $ 158 State 8 3 1 Total current income tax 218 38 159 Deferred income tax Federal (271 ) (1 ) 103 State (7 ) (2 ) (2 ) Total deferred income tax (278 ) (3 ) 101 Total income tax provision $ (60 ) $ 35 $ 260 On December 22, 2017, the Tax Act was signed into law. The provision for income taxes for the year ended December 31, 2017 included an expense of $140 million due to the enactment of the Tax Act. The $140 million expense included a $136 million expense for the remeasurement of deferred tax assets and liabilities to the Tax Act’s statutory rate of 21% and a $4 million expense for the remeasurement of tax contingencies, specifically state tax contingencies and interest accrued for tax contingencies. In 2018, the Company finalized its accounting related to the Tax Act and determined no adjustments were necessary. The principal reasons that the aggregate income tax provision is different from that computed by using the U.S. statutory rates of 21% for 2019 and 2018 and 35% for 2017 were as follows: Years Ended December 31, 2019 2018 2017 Tax at U.S. statutory rate 21.0 % 21.0 % 35.0 % Changes in taxes resulting from: Low income housing tax credits (15.3 ) (8.5 ) (7.4 ) Foreign tax credit, net of addback (9.5 ) (2.8 ) (2.7 ) Dividend received deduction (7.6 ) (4.2 ) (12.9 ) Audit adjustments (1.4 ) — — Uncertain tax positions 1.8 — — Impact of Tax Act — (1.1 ) 14.0 Taxes applicable to prior years — (1.1 ) — Other, net (0.4 ) 0.4 — Income tax provision (11.4 )% 3.7 % 26.0 % The decrease in the Company’s effective tax rate for the year ended December 31, 2019 compared to 2018 is primarily due to the lower pre-tax income relative to tax preferred items. The decrease in the Company’s effective tax rate for the year ended December 31, 2018 compared to 2017 was primarily the result of the decrease in the federal statutory rate and a $140 million expense in 2017 due to provisions of the Tax Act and an increase in low income housing credits, partially offset by lower levels of the dividends received deduction. Deferred income tax assets and liabilities result from temporary differences between the assets and liabilities measured for GAAP reporting versus income tax return purposes. Deferred income tax assets and liabilities are measured at the statutory rate of 21% as of both December 31, 2019 and 2018 . The significant components of the Company’s deferred income tax assets and liabilities, which are included net within other assets or other liabilities on the Consolidated Balance Sheets, were as follows: December 31, 2019 2018 (in millions) Deferred income tax assets Liabilities for policyholder account balances, future policy benefits and claims $ 940 $ 705 Investment related 210 144 Other 12 14 Gross deferred income tax assets 1,162 863 Less: valuation allowance 11 11 Total deferred income tax assets 1,151 852 Deferred income tax liabilities Deferred acquisition costs 446 423 Net unrealized gains on Available-for-Sale securities 182 37 Deferred sales inducement costs 50 53 Other 13 12 Gross deferred income tax liabilities 691 525 Net deferred income tax assets $ 460 $ 327 Included in the Company’s deferred income tax assets are tax benefits primarily related to state net operating losses of $9 million , net of federal benefit, which will expire beginning December 31, 2020 . Based on analysis of the Company’s tax position, management believes it is more likely than not that the Company will not realize certain state net operating losses of $9 million and state deferred tax assets of $2 million ; therefore, a valuation allowance of $11 million has been established. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits was as follows: 2019 2018 2017 (in millions) Balance at January 1 $ 19 $ 14 $ 59 Additions based on tax positions related to the current year 1 5 5 Additions for tax positions of prior years 34 1 — Reductions for tax positions of prior years (4 ) (1 ) (50 ) Audit settlements (11 ) — — Balance at December 31 $ 39 $ 19 $ 14 If recognized, approximately $17 million , $8 million and $5 million , net of federal tax benefits, of unrecognized tax benefits as of December 31, 2019 , 2018 and 2017 , respectively, would affect the effective tax rate. It is reasonably possible that the total amount of unrecognized tax benefits will change in the next 12 months. The Company estimates that the total amount of gross unrecognized tax benefits may decrease by approximately $30 million in the next 12 months primarily due to Internal Revenue Service (“IRS”) settlements and state exams. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. The Company recognized a net increase of $1 million in interest and penalties for the year ended December 31, 2019 , a net decrease of nil , and $1 million in interest and penalties for the years ended December 31, 2018 and 2017 , respectively. The Company had a payable of $2 million and $1 million related to accrued interest and penalties as of December 31, 2019 and 2018 , respectively. The Company files income tax returns as part of its inclusion in the consolidated federal income tax returns of Ameriprise Financial in the U.S. federal jurisdiction and various state jurisdictions. In the third quarter of 2019, the federal statutes of limitation closed for the 2014 and 2015 tax years. Ameriprise Financial’s tax returns for 2014 and 2015 are effectively settled except for one issue which was claimed on amended returns filed in the second quarter of 2019. The IRS is currently auditing Ameriprise Financial’s U.S. income tax returns for 2016 and 2017. Ameriprise Financial’s or the Company’s state income tax returns are currently under examination by various jurisdictions for years ranging from 2009 through 2017.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Guarantees and Contingencies [Text Block]	Commitments, Guarantees and Contingencies Commitments The following table presents the Company’s funding commitments as of December 31: 2019 2018 (in millions) Commercial mortgage loans $ 59 $ 50 Affordable housing and other real estate partnerships 22 59 Total funding commitments $ 81 $ 109 Guarantees The Company’s annuity and life products all have minimum interest rate guarantees in their fixed accounts. As of December 31, 2019 , these guarantees range from 1% to 5% . Contingencies Insurance companies have been the subject of increasing regulatory, legislative and judicial scrutiny. Numerous state and federal regulatory agencies have commenced examinations and other inquiries of insurance companies regarding sales and marketing practices (including sales to older consumers and disclosure practices), claims handling, and unclaimed property and escheatment practices and procedures. The Company has cooperated and will continue to cooperate with the applicable regulators. The Company is involved in the normal course of business in a number of other legal and arbitration proceedings concerning matters arising in connection with the conduct of its business activities. The Company believes that it is not a party to, nor are any of its properties the subject of, any pending legal, arbitration or regulatory investigation, examination or proceeding that is likely to have a material adverse effect on its consolidated financial condition, results of operations or liquidity. Notwithstanding the foregoing, it is possible that the outcome of any current or future legal, arbitration or regulatory proceeding could have a material impact on results of operations in any particular reporting period as the proceedings are resolved. Uncertain economic conditions, heightened and sustained volatility in the financial markets and significant financial reform legislation may increase the likelihood that clients and other persons or regulators may present or threaten legal claims or that regulators increase the scope or frequency of examinations of the Company or the insurance industry generally. Guaranty Fund Assessments RiverSource Life Insurance Company and RiverSource Life of NY are required by law to be a member of the guaranty fund association in every state where they are licensed to do business. In the event of insolvency of one or more unaffiliated insurance companies, the Company could be adversely affected by the requirement to pay assessments to the guaranty fund associations. The Company projects its cost of future guaranty fund assessments based on estimates of insurance company insolvencies provided by the National Organization of Life and Health Insurance Guaranty Associations (“NOLHGA”) and the amount of its premiums written relative to the industry-wide premium in each state. The Company accrues the estimated cost of future guaranty fund assessments when it is considered probable that an assessment will be imposed, the event obligating the Company to pay the assessment has occurred and the amount of the assessment can be reasonably estimated. The Company has a liability for estimated guaranty fund assessments and a related premium tax asset. As of both December 31, 2019 and 2018 , the estimated liability was $12 million . As of December 31, 2019 and 2018 , the related premium tax asset was $10 million and $11 million , respectively. The expected period over which guaranty fund assessments will be made and the related tax credits recovered is not known.

Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	Principles of Consolidation A variable interest entity (“VIE”) is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest (including substantive voting rights, the obligation to absorb the entity’s losses, or the rights to receive the entity’s returns) or has equity investors that do not provide sufficient financial resources for the entity to support its activities. Voting interest entities (“VOEs”) are those entities that do not qualify as a VIE. The Company consolidates VOEs in which it holds a greater than 50% voting interest. The Company generally accounts for entities using the equity method when it holds a greater than 20% but less than 50% voting interest or when the Company exercises significant influence over the entity. All other investments that are not reported at fair value as trading or Available-for-Sale securities are accounted for under the cost method when the Company owns less than a 20% voting interest and does not exercise significant influence. A VIE is consolidated by the reporting entity that determines it has both: • the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and • the obligation to absorb potentially significant losses or the right to receive potentially significant benefits to the VIE. All VIEs are assessed for consolidation under this framework. When evaluating entities for consolidation, the Company considers its contractual rights in determining whether it has the power to direct the activities of the VIE that most significantly impact the VIEs economic performance. In determining whether the Company has this power, it considers whether it is acting in a role that enables it to direct the activities that most significantly impact the economic performance of an entity or if it is acting in an agent role. In determining whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the Company considers an analysis of its rights to receive benefits such as investment returns and its obligation to absorb losses associated with any investment in the VIE in conjunction with other qualitative factors. Management and incentive fees that are at market and commensurate with the level of services provided, and where the Company does not hold other interests in the VIE that would absorb more than an insignificant amount of the VIE’s expected losses or receive more than an insignificant amount of the VIE’s expected residual returns, are not considered a variable interest and are excluded from the analysis. The consolidation guidance has a scope exception for reporting entities with interests in registered money market funds which do not have an explicit support agreement.
Amounts Based on Estimates and Assumptions [Policy Text Block]	Amounts Based on Estimates and Assumptions Accounting estimates are an integral part of the Consolidated Financial Statements. In part, they are based upon assumptions concerning future events. Among the more significant are those that relate to investment securities valuation and recognition of other-than-temporary impairments, DAC and the corresponding recognition of DAC amortization, valuation of derivative instruments and hedging activities, litigation reserves, future policy benefits and claims reserves and income taxes and the recognition of deferred tax assets and liabilities. These accounting estimates reflect the best judgment of management and actual results could differ.
Investments [Policy Text Block]	Investments Available-for-Sale Securities Available -for-Sale securities are carried at fair value with unrealized gains (losses) recorded in accumulated other comprehensive income (“AOCI”), net of impacts to DAC, deferred sales inducement costs (“DSIC”), unearned revenue, benefit reserves, reinsurance recoverables and income taxes. Gains and losses are recognized on a trade date basis in the Consolidated Statements of Income upon disposition of the securities. When the fair value of an investment is less than its amortized cost, the Company assesses whether or not: (i) it has the intent to sell the security (made a decision to sell) or (ii) it is more likely than not that the Company will be required to sell the security before its anticipated recovery. If either of these conditions exist, an other-than-temporary impairment is considered to have occurred and the Company recognizes an other-than-temporary impairment for the difference between the investment’s amortized cost and its fair value through earnings. For securities that do not meet the above criteria and the Company does not expect to recover a security’s amortized cost, the security is also considered other-than-temporarily impaired. For these securities, the Company separates the total impairment into the credit loss component and the amount of the loss related to other factors. The amount of the total other-than-temporary impairment related to credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to other factors is recognized in other comprehensive income (“OCI”), net of impacts to DAC, DSIC, unearned revenue, benefit reserves, reinsurance recoverables and income taxes. For Available-for-Sale securities that have recognized an other-than-temporary impairment through earnings, the difference between the amortized cost and the cash flows expected to be collected is accreted as interest income if through subsequent evaluation there is a sustained increase in the cash flow expected. Subsequent increases and decreases in the fair value of Available-for-Sale securities are included in OCI. The Company provides a supplemental disclosure on the face of its Consolidated Statements of Income that presents: (i) total other-than-temporary impairment losses recognized during the period and (ii) the portion of other-than-temporary impairment losses recognized in OCI. The sum of these amounts represents the credit-related portion of other-than-temporary impairments that were recognized in earnings during the period. The portion of other-than-temporary losses recognized in OCI includes: (i) the portion of other-than-temporary impairment losses related to factors other than credit recognized during the period and (ii) reclassifications of other-than-temporary impairment losses previously determined to be related to factors other than credit that are determined to be credit-related in the current period. The amount presented on the Consolidated Statements of Income as the portion of other-than-temporary losses recognized in OCI excludes subsequent increases and decreases in the fair value of these securities. For all securities that are considered temporarily impaired, the Company does not intend to sell these securities (has not made a decision to sell) and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. The Company believes that it will collect all principal and interest due on all investments that have amortized cost in excess of fair value that are considered only temporarily impaired. Factors the Company considers in determining whether declines in the fair value of fixed maturity securities are other-than-temporary include: (i) the extent to which the market value is below amortized cost; (ii) the duration of time in which there has been a significant decline in value; (iii) fundamental analysis of the liquidity, business prospects and overall financial condition of the issuer; and (iv) market events that could impact credit ratings, economic and business climate, litigation and government actions, and similar external business factors. In order to determine the amount of the credit loss component for corporate debt securities considered other-than-temporarily impaired, a best estimate of the present value of cash flows expected to be collected discounted at the security’s effective interest rate is compared to the amortized cost basis of the security. The significant inputs to cash flow projections consider potential debt restructuring terms, projected cash flows available to pay creditors and the Company’s position in the debtor’s overall capital structure. For structured investments (e.g., residential mortgage backed securities, commercial mortgage backed securities and asset backed securities), the Company also considers factors such as overall deal structure and its position within the structure, quality of underlying collateral, delinquencies and defaults, loss severities, recoveries, prepayments and cumulative loss projections in assessing potential other-than-temporary impairments of these investments. Based upon these factors, securities that have indicators of potential other-than-temporary impairment are subject to detailed review by management. Securities for which declines are considered temporary continue to be monitored by management until management determines there is no current risk of an other-than-temporary impairment. Other Investments Other
Financing Receivables [Policy Text Block]	Financing Receivables Mortgage Loans and Syndicated Loans Mortgage loans, net reflect the Company’s interest in commercial mortgage loans less the related allowance for loan losses. Syndicated loans represent the Company’s investment in below investment grade loan syndications. Mortgage loans and syndicated loans are stated at amortized cost, net of allowances for loan losses. Interest income is accrued on the unpaid principal balances of the loans as earned. Policy Loans Policy loans include life insurance policy and annuity loans and are reported at the unpaid principal balance, plus accrued interest. When originated, policy loan balances do not exceed the cash surrender value of the underlying products. As there is minimal risk of loss related to these loans, the Company does not record an allowance for loan losses for policy loans. Deposit Receivable For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability related to insurance risk in accordance with applicable accounting standards. If the Company determines that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, the Company records the agreement using the deposit method of accounting. Deposits made are included in other receivables. As amounts are received, consistent with the underlying contracts, the deposit receivable is adjusted. The deposit receivable is accreted using the interest method and the accretion is reported in other revenues. See Note 7 for additional information on the deposit receivable. Nonaccrual Loans Generally , loans are evaluated for or placed on nonaccrual status when either the collection of interest or principal has become 90 days past due or is otherwise considered doubtful of collection. When a loan is placed on nonaccrual status, unpaid accrued interest is reversed. Interest payments received on loans on nonaccrual status are generally applied to principal unless the remaining principal balance has been determined to be fully collectible. Commercial mortgage loans are evaluated for impairment when the loan is considered for nonaccrual status, restructured or foreclosure proceedings are initiated on the property. If it is determined that the fair value is less than the current loan balance, it is written down to fair value less estimated selling costs. Foreclosed property is recorded as real estate owned in other investments. Allowance for Loan Losses Management determines the adequacy of the allowance for loan losses based on the overall loan portfolio composition, recent and historical loss experience, and other pertinent factors, including when applicable, internal risk ratings, loan-to-value (“LTV”) ratios, FICO scores of the borrower, debt service coverage and occupancy rates, along with current economic and market conditions. This evaluation is inherently subjective as it requires estimates, which may be susceptible to significant change. The Company determines the amount of the allowance based on management’s assessment of relative risk characteristics of the loan portfolio. The allowance is recorded for homogeneous loan categories on a pool basis, based on an analysis of product mix and risk characteristics of the portfolio, including geographic concentration, bankruptcy experiences, and historical losses, adjusted for current trends and market conditions. While the Company attributes portions of the allowance to specific loan pools as part of the allowance estimation process, the entire allowance is available to absorb losses inherent in the total loan portfolio. The allowance is increased through provisions charged to net realized investment gains (losses) and reduced/increased by net charge-offs/recoveries. Impaired Loans The Company considers a loan to be impaired when, based on current information and events, it is probable the Company will not be able to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans may also include loans that have been modified in troubled debt restructurings as a concession to borrowers experiencing financial difficulties. Management evaluates for impairment all restructured loans and loans with higher impairment risk factors. Factors used by the Company to determine whether all amounts due on commercial mortgage loans will be collected, include but are not limited to, the financial condition of the borrower, performance of the underlying properties, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on property type and geographic location. The impairment recognized is measured as the excess of the loan’s recorded investment over: (i) the present value of its expected principal and interest payments discounted at the loan’s effective interest rate, (ii) the fair value of collateral or (iii) the loan’s observable market price. Restructured Loans
Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents Cash equivalents include highly liquid investments with original or remaining maturities at the time of purchase of 90 days or less.
Reinsurance [Policy Text Block]	Reinsurance The Company cedes insurance risk to other insurers under reinsurance agreements. The Company evaluates the financial condition of its reinsurers prior to entering into new reinsurance contracts and on a periodic basis during the contract term. Reinsurance premiums paid and benefits received are accounted for consistently with the basis used in accounting for the policies from which risk is reinsured and consistently with the terms of the reinsurance contracts. Reinsurance premiums for traditional life, long term care (“LTC”) and DI, net of the change in any prepaid reinsurance asset, are reported as a reduction of premiums. UL and VUL reinsurance premiums are reported as a reduction of policy and contract charges. In addition, for UL and VUL insurance policies, the net cost of reinsurance ceded, which represents the discounted amount of the expected cash flows between the reinsurer and the Company, is classified as an asset or contra asset and amortized over the estimated life of the policies in proportion to the estimated gross profits (“EGPs”) and is subject to retrospective adjustment in a manner similar to retrospective adjustment of DAC. The assumptions used to project the expected cash flows are consistent with those used for DAC valuation for the same contracts. Changes in the net cost of reinsurance are reflected as a component of policy and contract charges. Reinsurance recoveries are reported as components of benefits, claims, losses and settlement expenses. Insurance liabilities are reported before the effects of reinsurance. Policyholder account balances, future policy benefits and claims recoverable under reinsurance contracts are recorded as reinsurance recoverables. The Company also assumes life insurance and fixed annuity risk from other insurers in limited circumstances. Reinsurance premiums received and benefits paid are accounted for consistently with the basis used in accounting for the policies from which risk is reinsured and consistently with the terms of the reinsurance contracts. Liabilities for assumed business are recorded within policyholder account balances, future policy benefits and claims. See Note 9 for additional information on reinsurance.
Land, Buildings, Equipment and Software [Policy Text Block]	Land , Buildings, Equipment and Software Land , buildings, equipment and internally developed or purchased software are carried at cost less accumulated depreciation or amortization and are reflected within other assets. The Company uses the straight-line method of depreciation and amortization over periods ranging from three to 39 years . As of December 31, 2019 and 2018 , land, buildings, equipment and software were $129 million and $135 million , respectively, net of accumulated depreciation of $189 million and $174 million , respectively. Depreciation and amortization expense for the years ended December 31, 2019 , 2018 and 2017 was $16 million , $15 million and $15 million , respectively.
Derivative Instruments and Hedging Activities [Policy Text Block]	Derivative Instruments and Hedging Activities Freestanding derivative instruments are recorded at fair value and are reflected in other assets or other liabilities. The Company’s policy is to not offset fair value amounts recognized for derivatives and collateral arrangements executed with the same counterparty under the same master netting arrangement. The accounting for changes in the fair value of a derivative instrument depends on its intended use and the resulting hedge designation, if any. The Company primarily uses derivatives as economic hedges that are not designated as accounting hedges or do not qualify for hedge accounting treatment. The Company occasionally designates derivatives as (i) hedges of changes in the fair value of assets, liabilities, or firm commitments (“fair value hedges”) or (ii) hedges of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedges”). Derivative instruments that are entered into for hedging purposes are designated as such at the time the Company enters into the contract. For all derivative instruments that are designated for hedging activities, the Company documents all of the hedging relationships between the hedge instruments and the hedged items at the inception of the relationships. Management also documents its risk management objectives and strategies for entering into the hedge transactions. The Company assesses, at inception and on a quarterly basis, whether derivatives designated as hedges are highly effective in offsetting the fair value or cash flows of hedged items. If it is determined that a derivative is no longer highly effective as a hedge, the Company will discontinue the application of hedge accounting . For derivative instruments that do not qualify for hedge accounting or are not designated as accounting hedges, changes in fair value are recognized in current period earnings. Changes in fair value of derivatives are presented in the Consolidated Statements of Income based on the nature and use of the instrument. Changes in fair value of derivatives used as economic hedges are presented in the Consolidated Statements of Income with the corresponding change in the hedged asset or liability. For derivative instruments that qualify as fair value hedges, changes in the fair value of the derivatives, as well as changes in the fair value of the hedged assets, liabilities or firm commitments, are recognized on a net basis in current period earnings. The carrying value of the hedged item is adjusted for the change in fair value from the designated hedged risk. If a fair value hedge designation is removed or the hedge is terminated prior to maturity, previous adjustments to the carrying value of the hedged item are recognized into earnings over the remaining life of the hedged item. For derivative instruments that qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instruments is reported in AOCI and reclassified into earnings when the hedged item or transaction impacts earnings. The amount that is reclassified into earnings is presented in the Consolidated Statements of Income with the hedged instrument or transaction impact. Any ineffective portion of the gain or loss is reported in current period earnings as a component of net investment income. If a hedge designation is removed or a hedge is terminated prior to maturity, the amount previously recorded in AOCI is reclassified to earnings over the period that the hedged item impacts earnings. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related amounts previously recorded in AOCI are recognized in earnings immediately. The equity component of indexed annuities and IUL obligations are considered embedded derivatives. Additionally, certain annuities contain GMAB and GMWB provisions. The GMAB and the non-life contingent benefits associated with GMWB provisions are also considered embedded derivatives. See Note 13 for information regarding the Company’s fair value measurement of derivative instruments and Note 17 for the impact of derivatives on the Consolidated Statements of Income.
Deferred Acquisition Costs [Policy Text Block]	Deferred Acquisition Costs The Company incurs costs in connection with acquiring new and renewal insurance and annuity businesses. The portion of these costs which are incremental and direct to the acquisition of a new or renewal insurance policy or annuity contract are deferred. Significant costs capitalized include sales based compensation related to the acquisition of new and renewal insurance policies and annuity contracts, medical inspection costs for successful sales, and a portion of employee compensation and benefit costs based upon the amount of time spent on successful sales. Sales based compensation paid to AFS advisors and employees and third-party distributors is capitalized. Employee compensation and benefits costs which are capitalized relate primarily to sales efforts, underwriting and processing. All other costs which are not incremental direct costs of acquiring an insurance policy or annuity contract are expensed as incurred. The DAC associated with insurance policies or annuity contracts that are significantly modified or internally replaced with another contract are accounted for as contract terminations. These transactions are anticipated in establishing amortization periods and other valuation assumptions. The Company monitors other DAC amortization assumptions, such as persistency, mortality, morbidity, interest margin, variable annuity benefit utilization and maintenance expense levels each quarter and, when assessed independently, each could impact the Company’s DAC balances. The analysis of DAC balances and the corresponding amortization is a dynamic process that considers all relevant factors and assumptions described previously. Unless the Company’s management identifies a significant deviation over the course of the quarterly monitoring, management reviews and updates these DAC amortization assumptions annually in the third quarter of each year. Non-Traditional Long-Duration Products For non-traditional long-duration products (including variable and fixed deferred annuity contracts, UL and VUL insurance products), DAC are amortized based on projections of EGPs over amortization periods equal to the approximate life of the business. EGPs vary based on persistency rates (assumptions at which contractholders and policyholders are expected to surrender, make withdrawals from and make deposits to their contracts), mortality levels, client asset value growth rates (based on equity and bond market performance), variable annuity benefit utilization and interest margins (the spread between earned rates on invested assets and rates credited to contractholder and policyholder accounts) and are management’s best estimates. Management regularly monitors financial market conditions and actual contractholder and policyholder behavior experience and compares them to its assumptions. These assumptions are updated whenever it appears that earlier estimates should be revised. When assumptions are changed, the percentage of EGPs used to amortize DAC might also change. A change in the required amortization percentage is applied retrospectively; an increase in amortization percentage will result in a decrease in the DAC balance and an increase in DAC amortization expense, while a decrease in amortization percentage will result in an increase in the DAC balance and a decrease in DAC amortization expense. The impact on results of operations of changing assumptions can be either positive or negative in any particular period and is reflected in the period in which such changes are made. At each balance sheet date, the DAC balance is adjusted for the effect that would result from the realization of unrealized gains (losses) on securities impacting EGPs, with the related change recognized through AOCI. The client asset value growth rates are the rates at which variable annuity and VUL insurance contract values invested in separate accounts are assumed to appreciate in the future. The rates used vary by equity and fixed income investments. Management reviews and, where appropriate, adjusts its assumptions with respect to client asset value growth rates on a regular basis. The Company typically uses a five-year mean reversion process as a guideline in setting near-term equity fund growth rates based on a long-term view of financial market performance as well as recent actual performance. The suggested near-term equity fund growth rate is reviewed quarterly to ensure consistency with management’s assessment of anticipated equity market performance. DAC amortization expense recorded in a period when client asset value growth rates exceed management’s near-term estimate will typically be less than in a period when growth rates fall short of management’s near-term estimate. Traditional Long-Duration Products For traditional long-duration products (including traditional life and DI insurance products), DAC are generally amortized as a percentage of premiums over amortization periods equal to the premium paying period. The assumptions made in calculating the DAC balance and DAC amortization expense are consistent with those used in determining the liabilities. For traditional life and DI insurance products, the assumptions provide for adverse deviations in experience and are revised only if management concludes experience will be so adverse that DAC are not recoverable. If management concludes that DAC are not recoverable, DAC are reduced to the amount that is recoverable based on best estimate assumptions and there is a corresponding expense recorded in the Consolidated Statements of Income.
Deferred Sales Inducement Costs [Policy Text Block]	Deferred Sales Inducement Costs Sales inducement costs consist of bonus interest credits and premium credits added to certain annuity contract and insurance policy values. These benefits are capitalized to the extent they are incremental to amounts that would be credited on similar contracts without the applicable feature. The amounts capitalized are amortized using the same methodology and assumptions used to amortize DAC. DSIC is recorded in other assets and amortization of DSIC is recorded in benefits, claims, losses and settlement expenses.
Separate Account Assets and Liabilities [Policy Text Block]	Separate Account Assets and Liabilities Separate account assets represent funds held for the benefit of and separate account liabilities represent the obligation to the variable annuity contractholders and variable life insurance policyholders who have a contractual right to receive the benefits of their contract or policy and bear the related investment risk. Gains and losses on separate account assets accrue directly to the contractholder or policyholder and are not reported in the Company’s Consolidated Statements of Income. Separate account assets are recorded at fair value and separate account liabilities are equal to the assets recognized.
Policyholder Account Balances, Future Policy Benefits and Claims [Policy Text Block]	Policyholder Account Balances, Future Policy Benefits and Claims The Company establishes reserves to cover the risks associated with non-traditional and traditional long-duration products. Non-traditional long-duration products include variable annuity contracts, fixed annuity contracts and UL and VUL policies. Traditional long-duration products include term life, whole life, DI and LTC insurance products. Guarantees accounted for as insurance liabilities include GMDB, gain gross-up (“GGU”), guaranteed minimum income benefit (“GMIB”) and the life contingent benefits associated with GMWB. In addition, UL and VUL policies with product features that result in profits followed by losses are accounted for as insurance liabilities. Guarantees accounted for as embedded derivatives include GMAB and the non-life contingent benefits associated with GMWB. In addition, the portion of indexed annuities and IUL policies allocated to the indexed account is accounted for as an embedded derivative. Changes in future policy benefits and claims are reflected in earnings in the period adjustments are made. Where applicable, benefit amounts expected to be recoverable from reinsurance companies who share in the risk are separately recorded as reinsurance recoverables. Non-Traditional Long-Duration Products The liabilities for non-traditional long-duration products include fixed account values on variable and fixed annuities and UL and VUL policies, liabilities for guaranteed benefits associated with variable annuities and embedded derivatives for variable annuities, indexed annuities and IUL products. Liabilities for fixed account values on variable and fixed deferred annuities and UL and VUL policies are equal to accumulation values, which are the cumulative gross deposits and credited interest less withdrawals and various charges. A portion of the Company’s UL and VUL policies have product features that result in profits followed by losses from the insurance component of the contract. These profits followed by losses can be generated by the cost structure of the product or secondary guarantees in the contract. The secondary guarantee ensures that, subject to specified conditions, the policy will not terminate and will continue to provide a death benefit even if there is insufficient policy value to cover the monthly deductions and charges. The liability for these future losses is determined by estimating the death benefits in excess of account value and recognizing the excess over the estimated life based on expected assessments (e.g. cost of insurance charges, contractual administrative charges, similar fees and investment margin). See Note 11 for information regarding the liability for contracts with secondary guarantees. Liabilities for indexed annuity products and indexed accounts of IUL products are equal to the accumulation of host contract values covering guaranteed benefits and the fair value of embedded equity options. The GMDB and GGU liability is determined by estimating the expected value of death benefits in excess of the projected contract accumulation value and recognizing the excess over the estimated life based on expected assessments (e.g., mortality and expense fees, contractual administrative charges and similar fees). If elected by the contract owner and after a stipulated waiting period from contract issuance, a GMIB guarantees a minimum lifetime annuity based on a specified rate of contract accumulation value growth and predetermined annuity purchase rates. The GMIB liability is determined each period by estimating the expected value of annuitization benefits in excess of the projected contract accumulation value at the date of annuitization and recognizing the excess over the estimated life based on expected assessments. The liability for the life contingent benefits associated with GMWB provisions is determined by estimating the expected value of benefits that are contingent upon survival after the account value is equal to zero and recognizing the benefits over the estimated life based on expected assessments (e.g., mortality and expense fees, contractual administrative charges and similar fees). In determining the liabilities for GMDB, GGU, GMIB and the life contingent benefits associated with GMWB, the Company projects these benefits and contract assessments using actuarial models to simulate various equity market scenarios. Significant assumptions made in projecting future benefits and assessments relate to customer asset value growth rates, mortality, persistency, benefit utilization and investment margins and are consistent with those used for DAC valuation for the same contracts. As with DAC, unless the Company’s management identifies a significant deviation over the course of quarterly monitoring, management reviews and updates these assumptions annually in the third quarter of each year. See Note 11 for information regarding variable annuity guarantees. Liabilities for fixed annuities in a benefit or payout status utilize assumptions established as of the date the payout phase is initiated. The liabilities are the present value of future estimated payments reduced for mortality (which is based on industry mortality tables with modifications based on the Company’s experience) and discounted with interest rates. Embedded Derivatives The fair value of embedded derivatives related to GMAB and the non-life contingent benefits associated with GMWB provisions fluctuate based on equity, interest rate and credit markets and the estimate of the Company’s nonperformance risk, which can cause these embedded derivatives to be either an asset or a liability. The fair value of embedded derivatives related to indexed annuities and IUL fluctuate based on equity markets and interest rates and the estimate of the Company’s nonperformance risk and is a liability. See Note 13 for information regarding the fair value measurement of embedded derivatives. Traditional Long-Duration Products The liabilities for traditional long-duration products include liabilities for unpaid amounts on reported claims, estimates of benefits payable on claims incurred but not yet reported and estimates of benefits that will become payable on term life, whole life, DI and LTC policies as claims are incurred in the future. Liabilities for unpaid amounts on reported life insurance claims are equal to the death benefits payable under the policies. Liabilities for unpaid amounts on reported DI and LTC claims include any periodic or other benefit amounts due and accrued, along with estimates of the present value of obligations for continuing benefit payments. These unpaid amounts are calculated using anticipated claim continuance rates based on established industry tables, adjusted as appropriate for the Company’s experience. The discount rates used to calculate present values are based on average interest rates earned on assets supporting the liability for unpaid amounts. Liabilities for estimated benefits payable on claims that have been incurred but not yet reported are based on periodic analysis of the actual time lag between when a claim occurs and when it is reported. Liabilities for estimates of benefits that will become payable on future claims on term life, whole life and DI insurance policies are based on the net level premium and LTC policies are based on a gross premium valuation reflecting management’s current best estimate assumptions. Net level premium includes anticipated premium payments, mortality and morbidity rates, policy persistency and interest rates earned on assets supporting the liability. Gross premium valuation includes expected premium rate increases, benefit reductions, morbidity rates, policy persistency and interest rates earned on assets supporting the liability. Anticipated mortality and morbidity rates are based on established industry mortality and morbidity tables, with modifications based on the Company’s experience. Anticipated premium payments and persistency rates vary by policy form, issue age, policy duration and certain other pricing factors. For term life, whole life, DI and LTC policies, the Company utilizes best estimate assumptions as of the date the policy is issued with provisions for the risk of adverse deviation, as appropriate. After the liabilities are initially established, management performs premium deficiency tests using best estimate assumptions without provisions for adverse deviation annually in the third quarter of each year unless management identifies a material deviation over the course of quarterly monitoring. If the liabilities determined based on these best estimate assumptions are greater than the net reserves (i.e., GAAP reserves net of any DAC balance), the existing net reserves are adjusted by first reducing the DAC balance by the amount of the deficiency or to zero through a charge to current period earnings. If the deficiency is more than the DAC balance, then the net reserves are increased by the excess through a charge to current period earnings. If a premium deficiency is recognized, the assumptions as of the date of the loss recognition are locked in and used in subsequent periods. The assumptions for LTC insurance products are management’s best estimate as of the date of loss recognition and thus no longer provide for adverse deviations in experience. See Note 10 for information regarding the liabilities for traditional long-duration products.
Unearned Revenue Liability [Policy Text Block]	Unearned Revenue Liability The Company’s UL and VUL policies require payment of fees or other policyholder assessments in advance for services to be provided in future periods. These charges are deferred as unearned revenue and amortized using EGPs, similar to DAC. The unearned revenue liability is recorded in other liabilities and the amortization is recorded in policy and contract charges.
Income Taxes [Policy Text Block]	Income Taxes The Company qualifies as a life insurance company for federal income tax purposes. As such, the Company is subject to the Internal Revenue Code provisions applicable to life insurance companies. The Company’s taxable income is included in the consolidated federal income tax return of Ameriprise Financial. The Company provides for income taxes on a separate return basis, except that, under an agreement between Ameriprise Financial and the Company, tax benefits are recognized for losses to the extent they can be used in the consolidated return. It is the policy of Ameriprise Financial that it will reimburse its subsidiaries for any tax benefits recorded. The Company’s provision for income taxes represents the net amount of income taxes that the Company expects to pay or to receive from various taxing jurisdictions in connection with its operations. The Company provides for income taxes based on amounts that the Company believes it will ultimately owe taking into account the recognition and measurement for uncertain tax positions. Inherent in the provision for income taxes are estimates and judgments regarding the tax treatment of certain items. In connection with the provision for income taxes, the Consolidated Financial Statements reflect certain amounts related to deferred tax assets and liabilities, which result from temporary differences between the assets and liabilities measured for financial statement purposes versus the assets and liabilities measured for tax return purposes. The Company is required to establish a valuation allowance for any portion of its deferred tax assets that management believes will not be realized. Significant judgment is required in determining if a valuation allowance should be established and the amount of such allowance if required. Factors used in making this determination include estimates relating to the performance of the business. Consideration is given to, among other things in making this determination: (i) future taxable income exclusive of reversing temporary differences and carryforwards; (ii) future reversals of existing taxable temporary differences; (iii) taxable income in prior carryback years; and (iv) tax planning strategies. Management may need to identify and implement appropriate planning strategies to ensure its ability to realize deferred tax assets and reduce the likelihood of the establishment of a valuation allowance with respect to such assets. See Note 19 for additional information on the Company’s valuation allowance.
Revenue Recognition [Policy Text Block]	Revenue Recognition Premiums on traditional life, DI and LTC insurance products and immediate annuities with a life contingent feature are net of reinsurance ceded and are recognized as revenue when due. Interest income is accrued as earned using the effective interest method, which makes an adjustment of the yield for security premiums and discounts on all performing fixed maturity securities classified as Available-for-Sale so that the related security or loan recognizes a constant rate of return on the outstanding balance throughout its term. When actual prepayments differ significantly from originally anticipated prepayments, the retrospective effective yield is recalculated to reflect actual payments to date and updated future payment assumptions and a catch-up adjustment is recorded in the current period. In addition, the new effective yield, which reflects anticipated future payments, is used prospectively. Mortality and expense risk fees are based on a percentage of the fair value of assets held in the Company’s separate accounts and recognized when assessed. Variable annuity guaranteed benefit rider charges, cost of insurance charges on UL and VUL insurance and contract charges (net of reinsurance premiums and cost of reinsurance for UL insurance products) and surrender charges on annuities and UL and VUL insurance are recognized as revenue when assessed. Realized gains and losses on the sale of securities, other than equity method investments, are recognized using the specific identification method, on a trade date basis. Fees received under marketing support and distribution services arrangements are recognized as revenue when earned. See Note 4 for further discussion of accounting policies on revenue from contracts with customers.
