RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. 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.

The interim financial information in this report has not been audited. In the opinion of management, all adjustments necessary for fair statement of the consolidated financial position and results of operations for the interim periods have been made. Except for the out-of-period correction described below and the prior period adjustments for the retrospective adoption of the new revenue recognition accounting standard, all adjustments made were of a normal recurring nature.

In the first quarter of 2017, the Company recorded a $20 million decrease to income tax provision related to an out-of-period correction for a reversal of a tax reserve.

The accompanying Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Results of operations reported for interim periods are not necessarily indicative of results for the entire year. These Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on February 22, 2018 (“2017 10-K”).

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.

On January 1, 2018, the Company retrospectively adopted the new accounting standard for revenue recognition. See Note 2 and Note 3 for further information on the new accounting standard and the Company’s revenue from contracts with customers. The impact to the consolidated statements of income for the three months ended March 31, 2017 was a $4 million increase to policy and contract charges and a $4 million decrease to other revenues.

2. Recent Accounting Pronouncements

Adoption of New Accounting Standards

Revenue from Contracts with Customers

In May 2014, the Financial Accounting Standards Board (“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 is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted for interim and annual periods beginning after December 15, 2016. The standard may 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 3 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

8

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

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 is 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.

Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory

In October 2016, the FASB updated the accounting standards related to the recognition of income tax impacts on intra-entity transfers. The update requires entities to recognize the income tax consequences of intra-entity transfers, other than inventory, upon the transfer of the asset. The update requires the selling entity to recognize a current tax expense or benefit and the purchasing entity to recognize a deferred tax asset or liability when the transfer occurs. The standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted the standard on January 1, 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial condition or results of operations.

Future Adoption of New Accounting Standards

Income Statement – Reporting Comprehensive Income

In February 2018, the FASB updated the accounting standards related to the presentation of tax effects stranded in other comprehensive income (“OCI”). The update allows a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for tax effects stranded in AOCI resulting from the legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). The update is optional and entities may elect not to reclassify the stranded tax effects. The update is effective for fiscal years beginning after December 15, 2018. Entities may elect to 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. Early adoption is permitted in any period. The Company is currently evaluating whether it will elect to reclassify the stranded tax effects and the potential impact to the consolidated financial condition.

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 is effective for interim and annual periods beginning after December 15, 2018, and should be applied on a modified retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

Receivables - 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 current guidance, premiums are 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 is effective for interim and annual periods beginning after December 15, 2018, and should 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. Early adoption is permitted. The update is not expected to have a material impact on the Company’s consolidated financial condition or results of operations.

Financial Instruments – Measurement of Credit Losses

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. Early adoption will be permitted for interim and annual periods beginning after December 15, 2018. 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 is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

Leases – Recognition of Lease Assets and Liabilities on Balance Sheet

In February 2016, the FASB updated the accounting standards for leases. The update was issued to increase transparency and

9

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

comparability for the accounting of lease transactions. The standard will require 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 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. The update should be applied at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

3. Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the new accounting standard for revenue from contracts with customers on a retrospective basis.

The following table presents disaggregated revenue from contracts with customers and a reconciliation to total revenues reported on the Consolidated Statements of Income. Revenues related to manufacturing of insurance and annuity products or financial instruments are not in the scope of this standard and are included in the table below under the heading Revenue from other sources. See Note 2 for additional information on the adoption of the new accounting standard.

⁽¹⁾ Revenues not included in the scope of the revenue from contracts with customers standard.

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 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. The transfer agent and administration revenue is earned daily based on a fixed rate applied, as a percentage,

10

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

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, Ameriprise Financial Services, Inc., 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 life 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 $54 million as of both March 31, 2018 and December 31, 2017.

4. 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 $397 million and $408 million as of March 31, 2018 and December 31, 2017, respectively. The Company had an $80 million and a $97 million liability recorded as of March 31, 2018 and December 31, 2017, 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 above mentioned funding commitments.

The Company invests in structured investments which are considered VIEs for which it is not the sponsor. These structured investments typically invest in fixed income instruments and are managed by third parties and include asset backed securities, commercial mortgage backed securities 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 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 carrying value. The Company has no obligation to provide financial or other support to the structured investments beyond its investment nor has the Company provided any support to the structured investments. See Note 5 for additional information on these structured investments.

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 March 31, 2018 and December 31, 2017, investment securities with a fair value of $1.5 billion and $1.6 billion, respectively, were pledged to meet contractual obligations under derivative contracts and short-term borrowings, of which $627 million and $711 million, respectively, may be sold, pledged or rehypothecated by the counterparty.

As of March 31, 2018 and December 31, 2017, 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 March 31, 2018 and December 31, 2017, approximately $863 million and $906 million, respectively, of securities were internally rated by Columbia Management Investment Advisers, LLC, an affiliate of the Company, using criteria similar to those used by NRSROs.

A summary of fixed maturity securities by rating was as follows:

6. Financing Receivables

The Company’s financing receivables include commercial mortgage loans, syndicated loans and policy loans. Syndicated loans are reflected in other investments.

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 following table presents a rollforward of the allowance for loan losses for the three months ended and the ending balance of the allowance for loan losses by impairment method:

Collectively evaluated for impairment	2,987		3,015
Total	$	3,004	$	3,032

As of both March 31, 2018 and December 31, 2017, the Company’s recorded investment in financing receivables individually evaluated for impairment for which there was no related allowance for loan losses was $17 million.

During the three months ended March 31, 2018 and 2017, the Company purchased $25 million and $54 million, respectively, of syndicated loans and sold $3 million and nil, respectively, of syndicated loans.

Credit Quality Information

Nonperforming loans, which are generally loans 90 days or more past due, were $5 million as of both March 31, 2018 and December 31, 2017. 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 nil of total commercial mortgage loans as of both March 31, 2018 and December 31, 2017. 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.

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 both March 31, 2018 and December 31, 2017 were $5 million.

Troubled Debt Restructurings

The recorded investment in restructured loans was not material as of March 31, 2018 and December 31, 2017. The troubled debt restructurings did not have a material impact to the Company’s allowance for loan losses or income recognized for the three months endedMarch 31, 2018 and 2017. There are no commitments to lend additional funds to borrowers whose loans have been restructured.

9. Variable Annuity and Insurance Guarantees

The majority of the variable annuity contracts offered by the Company contain guaranteed minimum death benefit (“GMDB”) provisions. The Company also offers variable annuities with death benefit provisions that gross up the amount payable by a certain percentage of contract earnings, which are referred to as gain gross-up (“GGU”) benefits. In addition, the Company offers contracts with GMWB and GMAB provisions. The Company previously offered contracts containing guaranteed minimum income benefit (“GMIB”) provisions.

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:

⁽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.

11. 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:

The increase (decrease) to pretax income of the Company’s adjustment for nonperformance risk on the fair value of its embedded derivatives was $33 million and $(45) million, net of DAC, DSIC, unearned revenue amortization and the reinsurance accrual for the three months ended March 31, 2018 and 2017, respectively.

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 Company recognizes transfers between levels of the fair value hierarchy as of the beginning of the quarter in which each transfer occurred. For assets and liabilities held at the end of the reporting periods that are measured at fair value on a recurring basis, there were no transfers between Level 1 and Level 2.

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:

⁽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.

Sensitivity of Fair Value Measurements to Changes in Unobservable Inputs

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 result 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 result 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 result 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 result 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 result 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 and non-agency residential

24

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

mortgage backed securities. The fair value of corporate bonds and non-agency residential mortgage 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. In addition to the general pricing controls, the Company reviews the broker prices to ensure that the broker quotes are reasonable and, when available, compares prices of privately issued securities to public issues from the same issuer to ensure that the implicit illiquidity premium applied to the privately placed investment is reasonable considering investment characteristics, maturity, and average life of the investment.

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 March 31, 2018 and December 31, 2017. See Note 13 and Note 14 for further information on the credit risk of derivative instruments and related collateral.

Liabilities

Policyholder Account Balances, Future Policy Benefits and Claims

The Company values the embedded derivatives attributable to the provisions of certain variable annuity riders using internal valuation models. These models calculate fair value by discounting expected cash flows from benefits plus margins for profit, risk and expenses less embedded derivative fees. The projected cash flows used by these models include observable capital market assumptions and incorporate significant unobservable inputs related to contractholder behavior assumptions, implied volatility, and margins for risk, profit and expenses that 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 indexed annuity and IUL products. Significant inputs to the equity indexed annuity calculation include observable 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.

The Company’s Corporate Actuarial Department calculates the fair value of the embedded derivatives on a monthly basis. During this process, control checks are performed to validate the completeness of the data. Actuarial management approves various components of the valuation along with the final results. The change in the fair value of the embedded derivatives is reviewed monthly with senior management. The Level 3 inputs into the valuation are consistent with the pricing assumptions and updated as experience develops. Significant unobservable inputs that reflect policyholder behavior are reviewed quarterly along with other valuation assumptions.

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

March 31, 2018 and December 31, 2017. See Note 13 and Note 14 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 other-than-temporary impairment. The investments that are determined to be other-than-temporarily impaired 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). The balance of affordable housing partnerships measured at fair value on a nonrecurring basis was $157 million and $166 million as of March 31, 2018 and December 31, 2017, respectively, and is classified as Level 3 in the fair value hierarchy.

Policyholder account balances, future policy benefit and claims includes fixed annuities in deferral status, non-life contingent fixed annuities in payout status, indexed annuity host contracts and the fixed portion of a small number of variable annuity contracts classified as investment contracts. See Note 8 for additional information on these liabilities. Short-term borrowings include include repurchase agreement and FHLB borrowings. See Note 10 for further information on short-term borrowings. Other liabilities include future funding commitments to affordable housing partnerships and other real estate partnerships. Separate account liabilities relate to investment contracts.

12. Regulatory 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. 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, 2018, for certain derivative instruments used to economically hedge the interest rate exposure of certain variable annuity products that do not qualify for statutory hedge accounting. The permitted practice is intended to mitigate the impact to statutory surplus from the misalignment between variable annuity statutory reserves, which are not carried at fair value, and the fair value of derivatives used to economically hedge the interest rate exposure of non-life contingent living benefit guarantees. As of March 31, 2017 and December 31, 2017, application of this permitted practice resulted in an increase (decrease) to RiverSource Life Insurance Company’s statutory surplus of approximately $214 million and $(3) million, respectively.

13. 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:

⁽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 14 for additional disclosures related to the Company’s derivative instruments and Note 10 for additional disclosures related to the Company’s repurchase agreements.

14. 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.

The Company’s freestanding derivative instruments are all 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 13 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 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 primarily using futures, options, interest rate swaptions, interest rate swaps, total return swaps and variance swaps.

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 March 31, 2018:

		Premiums Payable		Premiums Receivable
		(in millions)
2018	(1)	$	180	$	76
2019		279		172
2020		199		131

2022		234		198
2023-2026		489		60
Total		$	1,550	$	756

⁽¹⁾ 2018 amounts represent the amounts payable and receivable for the period from April 1, 2018 to December 31, 2018.

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 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 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 three months endedMarch 31, 2018, the Company held no derivatives that were designated as cash flow hedges.

30

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

As of March 31, 2018, the Company expects to reclassify $1 million of deferred losses on derivative instruments from AOCI to earnings during the next 12 months that will be recorded in net investment income. These were originally losses on derivative instruments related to interest rate swaptions. During the three months endedMarch 31, 2018 and 2017, no hedge relationships were discontinued due to forecasted transactions no longer being expected to occur according to the original hedge strategy. For the three months endedMarch 31, 2018 and 2017, amounts recognized in earnings on derivative transactions that were ineffective were not material. See Note 15 for a summary of net unrealized gains (losses) included in AOCI related to previously designated cash flow hedges.

Currently, the longest period of time over which the Company is hedging exposure to the variability in future cash flows is one year and relates to interest credited on forecasted fixed premium product sales.

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 13 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 March 31, 2018 and December 31, 2017, the aggregate fair value of derivative contracts in a net liability position containing such credit contingent provisions was $277 million and $299 million, respectively. The aggregate fair value of assets posted as collateral for such instruments as of March 31, 2018 and December 31, 2017 was $275 million and $296 million, respectively. If the credit contingent provisions of derivative contracts in a net liability position as of March 31, 2018 and December 31, 2017 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 $2 million and $3 million, respectively.

Other comprehensive income (loss) related to net unrealized securities gains (losses) includes three components: (i) unrealized gains (losses) that arose from changes in the market value of securities that were held during the period; (ii) (gains) losses that were previously unrealized, but have been recognized in current period net income due to sales of Available-for-Sale securities and due to the reclassification of noncredit other-than-temporary impairment losses to credit losses; and (iii) other adjustments primarily consisting of changes in insurance and annuity asset and liability balances, such as DAC, DSIC, unearned revenue, benefit reserves and reinsurance recoverables, to reflect the expected impact on their carrying values had the unrealized gains (losses) been realized as of the respective balance sheet dates.

16. Income Taxes

In December of 2017, the Tax Act reduced federal income tax rates from 35% to 21% for tax years after 2017. The Company’s effective tax rate was 8.2% and 6.7% for the three months ended March 31,2018 and 2017, respectively. The effective tax rate for the first quarter of 2018 is lower than the statutory rate as a result of tax preferred items including foreign tax credits, low income housing tax credits and the dividends received deduction. The effective tax rate for the first quarter of 2017 was lower than the statutory rate as a result of tax preferred items including the dividends received deduction and low income housing tax credits, as well as a $20 million benefit related to an out-of-period correction for a reversal of a tax reserve.

Included in the Company’s deferred income tax assets are tax benefits related to state net operating losses of $9 million, net of federal benefit, which will expire beginning December 31, 2018.

TheCompanyisrequiredtoestablishavaluationallowancefor any portionofthedeferred tax assets that management believes will not be realized. Significant judgment is required in determining if a valuationallowanceshouldbeestablished,andthe amount of such allowance if required. Factors used in making this determination includeestimatesrelatingtotheperformanceofthebusiness. Considerationisgivento,amongotherthingsinmakingthisdetermination,(i)futuretaxableincomeexclusiveofreversingtemporarydifferencesandcarryforwards,(ii)futurereversalsofexisting taxable temporary differences, (iii) taxable income in prior carryback years, and (iv) tax planning strategies. Based on analysis of the Company’s tax position, management believes it is more likely than not that the results of future operations and implementation oftaxplanning strategies will not allow the Company to realize certain state deferred tax assets and state net operating losses. Thevaluation allowance for state deferred tax assets and state net operating losses was $11 million as of both March 31, 2018 and December 31, 2017.

As of March 31, 2018 and December 31, 2017, the Company had $15 million and $14 million, respectively, of gross unrecognized tax benefits. If recognized, approximately $5 million, net of federal tax benefits, of unrecognized tax benefits as of both March 31, 2018 and December 31, 2017, would affect the effective tax rate.

32

RIVERSOURCELIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

It is reasonably possible that the total amount of unrecognized tax benefits will change in the next 12 months. Based on the current audit position of the Company, it is estimated that the total amount of gross unrecognized tax benefits may decrease by $9 million to $10 million in the next 12 months primarily due to resolution of audits and statute expirations.

The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. The Company recognized nil and a net increase of $1 million in interest and penalties for the three months endedMarch 31, 2018 and 2017, respectively. As of both March 31, 2018 and December 31, 2017, the Company had a payable of $1 million, related to accrued interest and penalties.

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 first quarter of 2018, the Company received cash settlements for final resolution of the 2008 through 2010 Internal Revenue Service (“IRS”) audits. Ameriprise Financial’s audits are resolved through 2011. Ameriprise Financial’s 2012 and 2013 tax returns are at IRS appeals due to an unagreed issue. The IRS is currently auditing Ameriprise Financial’s U.S. income tax returns for 2014 and 2015. Ameriprise Financial’s or the Company’s state income tax returns are currently under examination by various jurisdictions for years ranging from 2005 through 2015.

17. 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.

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 March 31, 2018 and December 31, 2017, the estimated liability was $14 million, and the related premium tax asset was $12 million. The expected period over which guaranty fund assessments will be made and the related tax credits recovered is not known.

ITEM 2. MANAGEMENT’S NARRATIVE ANALYSIS

Overview

RiverSource Life Insurance Company and its subsidiaries are referred to collectively in this Form 10-Q as the “Company”. The following discussion and management’s narrative analysis of the financial condition and results of operations should be read in conjunction with the “Forward-Looking Statements” that follow, the Consolidated Financial Statements and Notes presented in Item 1 and its Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2018 (“2017 10-K”), as well as any current reports on Form 8-K and other publicly available information.

The Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Management’s narrative analysis is presented pursuant to General Instructions H(2)(a) of Form 10-Q in lieu of Management’s Discussion and Analysis of Financial Condition and Results of Operations.

See Note 1 to the Consolidated Financial Statements for additional information.

A significant portion of the Company’s annuity product sales derive from annuities funding qualified accounts, specifically IRAs. As a provider of products and services to tax-qualified retirement accounts, certain aspects of the Company’s business fall within the compliance oversight of the Departments of Labor and Treasury, particularly regarding the enforcement of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the tax reporting requirements applicable to such accounts. The Department of Labor published regulations in April 2016 that expanded the scope of who is considered an ERISA fiduciary and these regulations focus in large part on investment recommendations made by financial advisors, registered investment advisors, and other investment professionals to retirement investors, as well as how financial advisors are able to discuss IRA rollovers and how financial advisors and affiliates can transact with retirement investors. The first phase of the regulations went into effect on June 9, 2017 and requires financial advisors to make recommendations related to assets held in IRAs and employer sponsored retirement plans in accordance with the following impartial conduct standards: recommendations must be in the best interest of the client, compensation paid for the recommendations must be reasonable and the financial advisor must not make any misleading statements. The Company’s affiliated selling firms adopted policies and procedures designed to comply with the impartial conduct standards and communicated those policies and procedures to their affiliated advisors and staff. The second phase of the regulation pertaining to a new “best interest contract exemption” would put into place a number of additional requirements including entering into a best interest contract with clients, enhanced disclosure of fees and conflicts of interest, limits on differential commissions within a product category, the adoption of policies and procedures to ensure the best interest standard is met, and findings related to platforms that are limited to products that pay third-party payments and/or include proprietary products. The second phase of the regulation is currently scheduled to become effective on July 1, 2019. However, on March 15, 2018 the United States Court of Appeals for the Fifth Circuit issued a decision vacating the Department’s regulations in its entirety. The Fifth Circuit’s decision would be effective as of the date the court files its mandate (currently scheduled for May 7, 2018). Recently, several interested parties have filed a request to intervene and to have the case reheard by the Fifth Circuit en banc. It is not clear whether the Fifth Circuit will grant either of these motions.

In addition, the SEC recently proposed its own fiduciary standard that would apply to recommendations made by financial advisors who work on a commission basis and would apply regardless of the type of account (IRA or non-qualified) an investor holds. Furthermore, several states have either issued their own fiduciary rules or are considering doing so and those rules may extend to certain types of products (e.g. insurance and annuities, financial planning, etc.) or may broadly cover all recommendations made by financial advisors. The Certified Financial Planner Board has issued its own fiduciary standard that applies to financial advisors who hold a Certified Financial Planner designation. In light of the various fiduciary rules and regulations that have been proposed or finalized, the Company continues to exert significant efforts to evaluate and prepare to comply with each rule.

Critical Accounting Estimates

The accounting and reporting policies that the Company uses affect its Consolidated Financial Statements. Certain of the Company’s accounting and reporting policies are critical to an understanding of the Company’s financial condition and results of operations. In some cases, the application of these policies can be significantly affected by the estimates, judgments and assumptions made by management during the preparation of the Consolidated Financial Statements. These accounting policies are discussed in detail in “Management’s Narrative Analysis — Critical Accounting Estimates” in the Company’s 2017 10-K.

Recent Accounting Pronouncements

Overall

Net income increased $44 million or 19% to $279 million for the three months endedMarch 31, 2018 compared to $235 million for the prior year period. Pretax income increased $52 million or 21% to $304 million for the three months endedMarch 31, 2018 compared to $252 million for the prior year period.

The following impacts were significant drivers of the period-over-period change in pretax income:

• The market impact on variable annuity guaranteed benefits (net of hedges and the related deferred sales inducement costs (“DSIC”) and deferred acquisition costs (“DAC”) amortization) was an expense of $5 million for the three months ended March 31, 2018 compared to an expense of $36 million for the prior year period.

• The market impact on indexed universal life benefits (net of hedges and the related DAC amortization, unearned revenue amortization and the reinsurance accrual) was a benefit of $25 million for the three months ended March 31, 2018 compared to nil for the prior year period.

• The impact on DAC, DSIC and reserves for insurance features in non-traditional long-duration contracts from actual versus expected market performance based on the Company’s view of bond and equity performance was a benefit of $6 million (nil for DAC, nil for DSIC and $6 million for insurance features in non-traditional long-duration contracts) for the three months ended March 31, 2018 compared to a benefit of $19 million ($9 million for DAC, $2 million for DSIC and $8 million for insurance features in non-traditional long-duration contracts) for the prior year period.

The Company’s variable annuity account balances increased 3% to $78.7 billion as of March 31, 2018 compared to the prior year period due to market appreciation, partially offset by net outflows of $3.7 billion. Variable annuity net outflows for the first quarter of 2018 were lower than the prior year period driven by a 20% increase in sales, as well as lower lapses.

The Company’s fixed deferred annuity account balances declined 7% to $9.1 billion as of March 31, 2018 compared to the prior year period as older policies continue to lapse and new sales are limited due to low interest rates. Given the current interest rate environment, the Company’s current fixed deferred annuity book is expected to gradually run off and earnings on its fixed deferred annuity business will trend down.

Revenues

Net investment income decreased $13 million or 5% to $258 million for the three months endedMarch 31, 2018 compared to $271 million for the prior year period reflecting a decrease in investment income on fixed maturities primarily due to lower average invested assets and continued low interest rates.

35

RIVERSOURCE LIFE INSURANCE COMPANY

Policy and contract charges increased $23 million or 5% to $510 million for the three months endedMarch 31, 2018 compared to $487 million for the prior year period due to higher average fee rates on variable annuities.

Net realized investment gains were $5 million for the three months endedMarch 31, 2018 compared to $17 million for the prior year period and are related to net realized gains on Available-for-Sale securities due to sales, calls and tenders.

Benefits and Expenses

Benefits, claims, losses and settlement expenses decreased $41 million or 13% to $281 million for the three months endedMarch 31, 2018 compared to $322 million for the prior year period primarily reflecting the following items:

• A $78 million decrease in expense compared to the prior year period from the unhedged nonperformance credit spread risk adjustment on variable annuity guaranteed benefits. As the embedded derivative liability on which the nonperformance credit spread is applied increases (decreases), the impact of the nonperformance credit spread is favorable (unfavorable) to expense. The favorable impact of the nonperformance credit spread was $13 million for the three months endedMarch 31, 2018 compared to an unfavorable impact of $65 million for the prior year period.

• A $37 million increase in expense from other market impacts on variable annuity guaranteed benefits, net of hedges in place to offset those risks and the related DSIC amortization. This increase was the result of an unfavorable $221 million change in the market impact on variable annuity guaranteed living benefits reserves, a favorable $186 million change in the market impact on derivatives hedging the variable annuity guaranteed benefits and an unfavorable $2 million change in the DSIC offset. The main market drivers contributing to these changes are summarized below:

• Equity market impact on the variable annuity guaranteed living benefits liability net of the impact on the corresponding hedge assets resulted in an expense for the three months ended March 31, 2018 compared to a benefit in the prior year period.

• Interest rate impact on the variable annuity guaranteed living benefits liability net of the impact on the corresponding hedge assets resulted in a benefit for the three months ended March 31, 2018 compared to an expense in the prior year period.

• Other unhedged items, including the difference between the assumed and actual underlying separate account investment performance, fixed income credit exposures, transaction costs and various behavioral items, were a net unfavorable impact compared to the prior year period.

Interest credited to fixed accounts decreased $21 million or 13% to $141 million for the three months endedMarch 31, 2018 compared to $162 million for the prior year period primarily due to the market impact on indexed universal life benefits, net of hedges, which was a benefit of $21 million for the three months ended March 31, 2018 compared to nil for the prior year period.

Amortization of DAC increased $18 million or 32% to $75 million for the three months endedMarch 31, 2018 compared to $57 million for the prior year period primarily reflecting the following items:

• The DAC offset to the market impact on variable annuity guaranteed benefits (net of hedges and the related DSIC amortization) was an expense of $4 million for the three months ended March 31, 2018 compared to a benefit of $6 million for the prior year period.

• The DAC offset to the market impact on indexed universal life benefits (net of hedges, unearned revenue amortization and the reinsurance accrual) was an expense of $9 million for the three months ended March 31, 2018 compared to an expense of $1 million for the prior year period.

• The impact on DAC from actual versus expected market performance based on our view of bond and equity performance was nil for the three months ended March 31, 2018 compared to a benefit of $9 million for the prior year period reflecting favorable equity market returns.

• The positive impact on DAC from lower than expected lapses on variable annuities was $7 million.

Income Taxes

The Company’s effective tax rate was 8.2% for the three months endedMarch 31, 2018 compared to 6.7% for the prior year period. See Note 16 to the Consolidated Financial Statements for additional discussion on income taxes.

Market Risk

The Company’s primary market risk exposures are interest rate, equity price and credit risk. Equity price and interest rate fluctuations can have a significant impact on the Company’s results of operations, primarily due to the effects on asset-based fees and expenses, the “spread” income generated on its fixed deferred annuities, fixed insurance and the fixed portion of its variable annuities and variable insurance contracts, the value of DAC and DSIC assets, the value of liabilities for guaranteed benefits associated with its variable annuities and the value of derivatives held to hedge these benefits.

The Company’s earnings from fixed deferred annuities, fixed insurance, and the fixed portion of variable annuities and variable insurance contracts are based upon the spread between rates earned on assets held and the rates at which interest is credited to accounts. The Company primarily invests in fixed rate securities to fund the rate credited to clients. The Company guarantees an interest rate to the holders of these products. Investment assets and client liabilities generally differ as it relates to basis, repricing or maturity characteristics. Rates credited to clients’ accounts generally reset at shorter intervals than the yield on the underlying

36

RIVERSOURCE LIFE INSURANCE COMPANY

investments. Therefore, in an increasing interest rate environment, higher interest rates may be reflected in crediting rates to clients sooner than in rates earned on invested assets, which could result in a reduced spread between the two rates, reduced earned income and a negative impact on pretax income. However, the current low interest rate environment is resulting in interest rates below the level of some of the Company’s liability guaranteed minimum interest rates (“GMIRs”). Hence, a modest rise in interest rates would not necessarily result in changes to all the liability credited rates while projected asset purchases would capture the full increase in interest rates. This dynamic would result in widening spreads under a modestly rising rate scenario given the current relationship between the current level of interest rates and the underlying GMIRs on the business.

As a result of the low interest rate environment, the Company’s current reinvestment yields are generally lower than the current portfolio yield. The Company expects its portfolio income yields to continue to decline in future periods if interest rates remain low. The carrying value and weighted average yield of total non-structured fixed maturity securities and commercial mortgage loans in the Company’s investment portfolio that may generate proceeds to reinvest through March 31, 2020 due to prepayment, maturity or call activity at the option of the issuer, excluding securities with a make-whole provision, were $3.1 billion and 5.3%, respectively, as of March 31, 2018. In addition, residential mortgage-backed securities, which are subject to prepayment risk as a result of the low interest rate environment, totaled $2.9 billion and had a weighted average yield of 3.3% as of March 31, 2018. While these amounts represent investments that could be subject to reinvestment risk, it is also possible that these investments will be used to fund liabilities or may not be prepaid and will remain invested at their current yields. In addition to the interest rate environment, the mix of benefit payments versus product sales as well as the timing and volumes associated with such mix may impact the Company’s investment yield. Furthermore, reinvestment activities and the associated investment yield may also be impacted by corporate strategies implemented at management’s discretion. The average yield for investment purchases during the three months endedMarch 31, 2018 was approximately 4.0%.

The reinvestment of proceeds from maturities, calls and prepayments at rates below the current portfolio yield, which may be below the level of some liability GMIRs, will have a negative impact to future operating results. To mitigate the unfavorable impact that the low interest rate environment has on the Company’s spread income, it assesses reinvestment risk in its investment portfolio and monitors this risk in accordance with its asset/liability management framework. In addition, the Company may reduce the crediting rates on its fixed products when warranted, subject to guaranteed minimums.

In addition to the fixed rate exposures noted above, the Company also has the following variable annuity guarantee benefits: guaranteed minimum withdrawal benefits (“GMWB”), guaranteed minimum accumulation benefits (“GMAB”), guaranteed minimum death benefits (“GMDB”) and guaranteed minimum income benefits (“GMIB”). Each of these benefits guarantees payouts to the annuity holder under certain specific conditions regardless of the performance of the underlying invested assets.

The variable annuity guarantees continue to be managed by utilizing a hedging program which attempts to match the sensitivity of the assets with the sensitivity of the liabilities. This approach works with the premise that matched sensitivities will produce a highly effective hedging result. The Company’s comprehensive hedging program focuses mainly on first order sensitivities of assets and liabilities: Equity Market Level (Delta), Interest Rate Level (Rho) and Volatility (Vega). Additionally, various second order sensitivities are managed. The Company uses various index options across the term structure, interest rate swaps and swaptions, total return swaps and futures to manage the risk exposures. The exposures are measured and monitored daily and adjustments to the hedge portfolio are made as necessary.

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. The Company assesses this residual risk under a range of scenarios in creating and executing the macro hedge program. 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 used contain settlement provisions linked to both equity returns and interest rates; the remaining are interest rate contracts or equity contracts. The macro hedge program could result in additional earnings volatility as changes in the value of the macro hedge derivatives, which are designed to reduce statutory capital volatility, may not be closely aligned to changes in the variable annuity guarantee embedded derivatives.

To evaluate interest rate and equity price risk, the Company performs sensitivity testing which measures the impact on pretax income from the sources listed below for a 12-month period following a hypothetical 100 basis point increase in interest rates or a hypothetical 10% decline in equity prices. The interest rate risk test assumes a sudden 100 basis point parallel shift in the yield curve, with rates then staying at those levels for the next 12 months. The equity price risk test assumes a sudden 10% drop in equity prices, with equity prices then staying at those levels for the next 12 months. In estimating the values of variable annuity riders, indexed annuities, indexed universal life insurance and the associated hedge assets, the Company assumed no change in implied market volatility despite the 10% drop in equity prices.

N/A Not Applicable.

⁽¹⁾  Market impact on DAC and DSIC amortization resulting from lower projected profits.

⁽²⁾  In estimating the impact on DAC and DSIC amortization resulting from lower projected profits, the Company has not changed its assumed equity asset growth rates. This is a significantly more conservative estimate than if the Company assumed management follows its mean reversion guideline and increased near-term rates to recover the drop in equity values over a five-year period. The Company makes this same conservative assumption in estimating the impact from GMDB and GMIB riders and the life contingent benefits associated with GMWB.

⁽³⁾  Market impact on DAC and DSIC amortization related to variable annuity riders is modeled net of hedge impact.

⁽⁴⁾  The market impact of the macro hedge program is modeled net of any related impact to DAC and DSIC amortization.

The above results compare to an estimated negative net impact to pretax income of $399 million related to a 10% equity price decline and an estimated positive net impact to pretax income of $97 million related to a 100 basis point increase in interest rates as of December 31, 2017. The change in interest rate exposure was driven by variable annuity riders primarily due to changes in market rates.

Net impacts shown in the above table from GMWB riders result largely from differences between the liability valuation basis and the hedging basis. Liabilities are valued using fair value accounting principles, with risk margins incorporated in contractholder behavior assumptions and with discount rates increased to reflect a current market estimate of the Company’s risk of nonperformance specific to these liabilities. The Company’s hedging is based on its determination of economic risk, which excludes certain items in the liability

38

RIVERSOURCE LIFE INSURANCE COMPANY

valuation including the nonperformance spread risk.

Actual results could differ materially from those illustrated above as they are based on a number of estimates and assumptions. These include assuming that implied market volatility does not change when equity prices fall by 10%, that management does not increase assumed equity asset growth rates to anticipate recovery of the drop in equity values when valuing DAC, DSIC and the liability values associated with GMDB, GMIB and the life contingent benefits associated with GMWB; and that the 100 basis point increase in interest rates is a parallel shift of the yield curve. Furthermore, the Company has not tried to anticipate changes in client preferences for different types of assets or other changes in client behavior, nor has the Company tried to anticipate actions management might take to increase revenues or reduce expenses in these scenarios.

The selection of a 100 basis point interest rate increase as well as a 10% equity price decline should not be construed as a prediction of future market events. Impacts of larger or smaller changes in interest rates or equity prices may not be proportional to those shown for a 100 basis point increase in interest rates or a 10% decline in equity prices.

Fair Value Measurements

The Company reports certain assets and liabilities at fair value; specifically, separate account assets, derivatives, embedded derivatives, most investments and cash equivalents. Fair value assumes the exchange of assets or liabilities occurs in orderly transactions and is not the result of a forced liquidation or distressed sale. The Company includes actual market prices, or observable inputs, in its fair value measurements to the extent available. Broker quotes are obtained when quotes from pricing services are not available. The Company validates prices obtained from third parties through a variety of means such as: price variance analysis, subsequent sales testing, stale price review, price comparison across pricing vendors and due diligence reviews of vendors. See Note 11 to the Consolidated Financial Statements for additional information on the Company’s fair value measurements.

Fair Value of Liabilities and Nonperformance Risk

Companies are required to measure the fair value of liabilities at the price that would be received to transfer the liability to a market participant (an exit price). Since there is not a market for the Company’s obligations of its variable annuity riders, indexed annuities and indexed universal life insurance, the Company considers the assumptions participants in a hypothetical market would make to reflect an exit price. As a result, the Company adjusts the valuation of variable annuity riders, indexed annuities and indexed universal life insurance by updating certain contractholder assumptions, adding explicit margins to provide for profit, risk and expenses, and adjusting the rates used to discount expected cash flows to reflect a current market estimate of the Company’s nonperformance risk. The nonperformance risk adjustment is based on observable market data adjusted to estimate the risk of the Company not fulfilling these liabilities. Consistent with general market conditions, this estimate resulted in a spread over the LIBOR swap curve as of March 31, 2018. As the Company’s estimate of this spread widens or tightens, the liability will decrease or increase. If this nonperformance credit spread moves to a zero spread over the LIBOR swap curve, the reduction to future net income would be approximately $295 million, net of DAC, DSIC, unearned revenue amortization, the reinsurance accrual and income taxes (calculated at the statutory tax rate of 21%), based on March 31, 2018 credit spreads.

Liquidity and Capital Resources

Liquidity Strategy

The liquidity requirements of the Company are generally met by funds provided by investment income, maturities and periodic repayments of investments, premiums and proceeds from sales of investments, fixed annuity and fixed insurance deposits as well as capital contributions from its parent, Ameriprise Financial, Inc. (“Ameriprise Financial”). Other liquidity sources the Company has established are short-term borrowings and available lines of credit with Ameriprise Financial aggregating $996 million.

The Company enters into short-term borrowings, which may include repurchase agreements and Federal Home Loan Bank (“FHLB”) advances to reduce reinvestment risk. Short-term borrowings allow the Company to receive cash to reinvest in longer-duration assets, while paying back the short-term debt with cash flows generated by the fixed income portfolio. The balance of repurchase agreements as of both March 31, 2018 and December 31, 2017 was $50 million which is collateralized with agency residential mortgage backed securities and commercial mortgage backed securities from the Company’s investment portfolio. RiverSource Life Insurance Company is a member of the FHLB of Des Moines, which provides RiverSource Life Insurance Company access to collateralized borrowings. As of March 31, 2018, the Company had estimated maximum borrowing capacity of $5.8 billion under the FHLB facility, of which $151 million was outstanding and is collateralized with commercial mortgage backed securities.

The primary uses of funds are policy benefits, commissions, other product-related acquisition and sales inducement costs, operating expenses, policy loans, dividends to Ameriprise Financial and investment purchases. The Company routinely reviews its sources and uses of funds in order to meet its ongoing obligations.

In 2009, the Company established an agreement to protect its exposure to Genworth Life Insurance Company (“GLIC”) for its reinsured LTC. In 2016, substantial enhancements to this reinsurance protection agreement were finalized. The terms of these confidential provisions within the agreement have been shared, in the normal course of regular reviews, with the Company’s domiciliary regulator and rating agencies. Management believes that this agreement and offsetting non LTC legacy arrangements with Genworth will enable the Company to recover on all net exposure in the event of an insolvency of GLIC.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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.

The interim financial information in this report has not been audited. In the opinion of management, all adjustments necessary for fair statement of the consolidated financial position and results of operations for the interim periods have been made. Except for the out-of-period correction described below and the prior period adjustments for the retrospective adoption of the new revenue recognition accounting standard, all adjustments made were of a normal recurring nature.

In the first quarter of 2017, the Company recorded a $20 million decrease to income tax provision related to an out-of-period correction for a reversal of a tax reserve.

The accompanying Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Results of operations reported for interim periods are not necessarily indicative of results for the entire year. These Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission on February 22, 2018 (“2017 10-K”).

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.

On January 1, 2018, the Company retrospectively adopted the new accounting standard for revenue recognition. See Note 2 and Note 3 for further information on the new accounting standard and the Company’s revenue from contracts with customers. The impact to the consolidated statements of income for the three months ended March 31, 2017 was a $4 million increase to policy and contract charges and a $4 million decrease to other revenues.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Adoption of New Accounting Standards

Revenue from Contracts with Customers

In May 2014, the Financial Accounting Standards Board (“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 is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted for interim and annual periods beginning after December 15, 2016. The standard may 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 3 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 is 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.

Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory

In October 2016, the FASB updated the accounting standards related to the recognition of income tax impacts on intra-entity transfers. The update requires entities to recognize the income tax consequences of intra-entity transfers, other than inventory, upon the transfer of the asset. The update requires the selling entity to recognize a current tax expense or benefit and the purchasing entity to recognize a deferred tax asset or liability when the transfer occurs. The standard is effective for interim and annual periods beginning after December 15, 2017. The Company adopted the standard on January 1, 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial condition or results of operations.

Future Adoption of New Accounting Standards

Income Statement – Reporting Comprehensive Income

In February 2018, the FASB updated the accounting standards related to the presentation of tax effects stranded in other comprehensive income (“OCI”). The update allows a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for tax effects stranded in AOCI resulting from the legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). The update is optional and entities may elect not to reclassify the stranded tax effects. The update is effective for fiscal years beginning after December 15, 2018. Entities may elect to 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. Early adoption is permitted in any period. The Company is currently evaluating whether it will elect to reclassify the stranded tax effects and the potential impact to the consolidated financial condition.

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 is effective for interim and annual periods beginning after December 15, 2018, and should be applied on a modified retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

Receivables - 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 current guidance, premiums are 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 is effective for interim and annual periods beginning after December 15, 2018, and should 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. Early adoption is permitted. The update is not expected to have a material impact on the Company’s consolidated financial condition or results of operations.

Financial Instruments – Measurement of Credit Losses

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. Early adoption will be permitted for interim and annual periods beginning after December 15, 2018. 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 is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

Leases – Recognition of Lease Assets and Liabilities on Balance Sheet

In February 2016, the FASB updated the accounting standards for leases. The update was issued to increase transparency and comparability for the accounting of lease transactions. The standard will require 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 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. The update should be applied at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of the standard on its consolidated financial condition and results of operations.

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 $397 million and $408 million as of March 31, 2018 and December 31, 2017, respectively. The Company had an $80 million and a $97 million liability recorded as of March 31, 2018 and December 31, 2017, 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 above mentioned funding commitments.

The Company invests in structured investments which are considered VIEs for which it is not the sponsor. These structured investments typically invest in fixed income instruments and are managed by third parties and include asset backed securities, commercial mortgage backed securities 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 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 carrying value. The Company has no obligation to provide financial or other support to the structured investments beyond its investment nor has the Company provided any support to the structured investments. See Note 5 for additional information on these structured investments.

As of March 31, 2018 and December 31, 2017, investment securities with a fair value of $1.5 billion and $1.6 billion, respectively, were pledged to meet contractual obligations under derivative contracts and short-term borrowings, of which $627 million and $711 million, respectively, may be sold, pledged or rehypothecated by the counterparty.

As of March 31, 2018 and December 31, 2017, 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 March 31, 2018 and December 31, 2017, approximately $863 million and $906 million, respectively, of securities were internally rated by Columbia Management Investment Advisers, LLC, an affiliate of the Company, using criteria similar to those used by NRSROs.

A summary of fixed maturity securities by rating was as follows:

Receivables [Abstract]

Financing Receivables [Text Block]

Financing Receivables

The Company’s financing receivables include commercial mortgage loans, syndicated loans and policy loans. Syndicated loans are reflected in other investments.

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 following table presents a rollforward of the allowance for loan losses for the three months ended and the ending balance of the allowance for loan losses by impairment method:

	March 31,
	2018		2017
	(in millions)
Beginning balance	$	22	$	25
Provisions	—		—
Ending balance	$	22	$	25
Individually evaluated for impairment	$	—	$	2
Collectively evaluated for impairment	22		23

The recorded investment in financing receivables by impairment method was as follows:

	March 31, 2018		December 31, 2017
	(in millions)
Individually evaluated for impairment	$	17	$	17
Collectively evaluated for impairment	2,987		3,015
Total	$	3,004	$	3,032

As of both March 31, 2018 and December 31, 2017, the Company’s recorded investment in financing receivables individually evaluated for impairment for which there was no related allowance for loan losses was $17 million.

During the three months ended March 31, 2018 and 2017, the Company purchased $25 million and $54 million, respectively, of syndicated loans and sold $3 million and nil, respectively, of syndicated loans.

Credit Quality Information

Nonperforming loans, which are generally loans 90 days or more past due, were $5 million as of both March 31, 2018 and December 31, 2017. 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 nil of total commercial mortgage loans as of both March 31, 2018 and December 31, 2017. 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
	March 31, 2018		December 31, 2017		March 31, 2018		December 31, 2017

Syndicated Loans

The recorded investment in syndicated loans as of March 31, 2018 and December 31, 2017 was $402 million and $397 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 both March 31, 2018 and December 31, 2017 were $5 million.

Troubled Debt Restructurings

The recorded investment in restructured loans was not material as of March 31, 2018 and December 31, 2017. The troubled debt restructurings did not have a material impact to the Company’s allowance for loan losses or income recognized for the three months endedMarch 31, 2018 and 2017. There are no commitments to lend additional funds to borrowers whose loans have been restructured.

Variable Annuity and Insurance Guarantees

Insurance [Abstract]

Variable Annuity and Insurance Guarantees

Variable Annuity and Insurance Guarantees

The majority of the variable annuity contracts offered by the Company contain guaranteed minimum death benefit (“GMDB”) provisions. The Company also offers variable annuities with death benefit provisions that gross up the amount payable by a certain percentage of contract earnings, which are referred to as gain gross-up (“GGU”) benefits. In addition, the Company offers contracts with GMWB and GMAB provisions. The Company previously offered contracts containing guaranteed minimum income benefit (“GMIB”) provisions.

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:

⁽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 [Table Text Block]

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:

The increase (decrease) to pretax income of the Company’s adjustment for nonperformance risk on the fair value of its embedded derivatives was $33 million and $(45) million, net of DAC, DSIC, unearned revenue amortization and the reinsurance accrual for the three months ended March 31, 2018 and 2017, respectively.

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 Company recognizes transfers between levels of the fair value hierarchy as of the beginning of the quarter in which each transfer occurred. For assets and liabilities held at the end of the reporting periods that are measured at fair value on a recurring basis, there were no transfers between Level 1 and Level 2.

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:

	March 31, 2018

					Surrender rate	0.1	%	-	74.7%
					Market volatility (3)	3.7	%	-	16.1%
					Nonperformance risk (1)	71 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.

Sensitivity of Fair Value Measurements to Changes in Unobservable Inputs

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 result 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 result 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 result 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 result 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 result 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 and non-agency residential mortgage backed securities. The fair value of corporate bonds and non-agency residential mortgage 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. In addition to the general pricing controls, the Company reviews the broker prices to ensure that the broker quotes are reasonable and, when available, compares prices of privately issued securities to public issues from the same issuer to ensure that the implicit illiquidity premium applied to the privately placed investment is reasonable considering investment characteristics, maturity, and average life of the investment.

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 March 31, 2018 and December 31, 2017. See Note 13 and Note 14 for further information on the credit risk of derivative instruments and related collateral.

Liabilities

Policyholder Account Balances, Future Policy Benefits and Claims

The Company values the embedded derivatives attributable to the provisions of certain variable annuity riders using internal valuation models. These models calculate fair value by discounting expected cash flows from benefits plus margins for profit, risk and expenses less embedded derivative fees. The projected cash flows used by these models include observable capital market assumptions and incorporate significant unobservable inputs related to contractholder behavior assumptions, implied volatility, and margins for risk, profit and expenses that 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 indexed annuity and IUL products. Significant inputs to the equity indexed annuity calculation include observable 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.

The Company’s Corporate Actuarial Department calculates the fair value of the embedded derivatives on a monthly basis. During this process, control checks are performed to validate the completeness of the data. Actuarial management approves various components of the valuation along with the final results. The change in the fair value of the embedded derivatives is reviewed monthly with senior management. The Level 3 inputs into the valuation are consistent with the pricing assumptions and updated as experience develops. Significant unobservable inputs that reflect policyholder behavior are reviewed quarterly along with other valuation assumptions.

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 March 31, 2018 and December 31, 2017. See Note 13 and Note 14 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 other-than-temporary impairment. The investments that are determined to be other-than-temporarily impaired 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). The balance of affordable housing partnerships measured at fair value on a nonrecurring basis was $157 million and $166 million as of March 31, 2018 and December 31, 2017, respectively, and is classified as Level 3 in the fair value hierarchy.

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:

⁽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.

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.

The Company’s freestanding derivative instruments are all 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 13 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:

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 primarily using futures, options, interest rate swaptions, interest rate swaps, total return swaps and variance swaps.

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 March 31, 2018:

		Premiums Payable		Premiums Receivable
		(in millions)
2018	(1)	$	180	$	76
2019		279		172
2020		199		131
2021		169		119
2022		234		198
2023-2026		489		60
Total		$	1,550	$	756

⁽¹⁾ 2018 amounts represent the amounts payable and receivable for the period from April 1, 2018 to December 31, 2018.

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 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 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 three months endedMarch 31, 2018, the Company held no derivatives that were designated as cash flow hedges.

As of March 31, 2018, the Company expects to reclassify $1 million of deferred losses on derivative instruments from AOCI to earnings during the next 12 months that will be recorded in net investment income. These were originally losses on derivative instruments related to interest rate swaptions. During the three months endedMarch 31, 2018 and 2017, no hedge relationships were discontinued due to forecasted transactions no longer being expected to occur according to the original hedge strategy. For the three months endedMarch 31, 2018 and 2017, amounts recognized in earnings on derivative transactions that were ineffective were not material. See Note 15 for a summary of net unrealized gains (losses) included in AOCI related to previously designated cash flow hedges.

Currently, the longest period of time over which the Company is hedging exposure to the variability in future cash flows is one year and relates to interest credited on forecasted fixed premium product sales.

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 13 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 March 31, 2018 and December 31, 2017, the aggregate fair value of derivative contracts in a net liability position containing such credit contingent provisions was $277 million and $299 million, respectively. The aggregate fair value of assets posted as collateral for such instruments as of March 31, 2018 and December 31, 2017 was $275 million and $296 million, respectively. If the credit contingent provisions of derivative contracts in a net liability position as of March 31, 2018 and December 31, 2017 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 $2 million and $3 million, respectively.

Income Taxes

Income Taxes

In December of 2017, the Tax Act reduced federal income tax rates from 35% to 21% for tax years after 2017. The Company’s effective tax rate was 8.2% and 6.7% for the three months ended March 31,2018 and 2017, respectively. The effective tax rate for the first quarter of 2018 is lower than the statutory rate as a result of tax preferred items including foreign tax credits, low income housing tax credits and the dividends received deduction. The effective tax rate for the first quarter of 2017 was lower than the statutory rate as a result of tax preferred items including the dividends received deduction and low income housing tax credits, as well as a $20 million benefit related to an out-of-period correction for a reversal of a tax reserve.

Included in the Company’s deferred income tax assets are tax benefits related to state net operating losses of $9 million, net of federal benefit, which will expire beginning December 31, 2018.

TheCompanyisrequiredtoestablishavaluationallowancefor any portionofthedeferred tax assets that management believes will not be realized. Significant judgment is required in determining if a valuationallowanceshouldbeestablished,andthe amount of such allowance if required. Factors used in making this determination includeestimatesrelatingtotheperformanceofthebusiness. Considerationisgivento,amongotherthingsinmakingthisdetermination,(i)futuretaxableincomeexclusiveofreversingtemporarydifferencesandcarryforwards,(ii)futurereversalsofexisting taxable temporary differences, (iii) taxable income in prior carryback years, and (iv) tax planning strategies. Based on analysis of the Company’s tax position, management believes it is more likely than not that the results of future operations and implementation oftaxplanning strategies will not allow the Company to realize certain state deferred tax assets and state net operating losses. Thevaluation allowance for state deferred tax assets and state net operating losses was $11 million as of both March 31, 2018 and December 31, 2017.

As of March 31, 2018 and December 31, 2017, the Company had $15 million and $14 million, respectively, of gross unrecognized tax benefits. If recognized, approximately $5 million, net of federal tax benefits, of unrecognized tax benefits as of both March 31, 2018 and December 31, 2017, 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. Based on the current audit position of the Company, it is estimated that the total amount of gross unrecognized tax benefits may decrease by $9 million to $10 million in the next 12 months primarily due to resolution of audits and statute expirations.

The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. The Company recognized nil and a net increase of $1 million in interest and penalties for the three months endedMarch 31, 2018 and 2017, respectively. As of both March 31, 2018 and December 31, 2017, the Company had a payable of $1 million, related to accrued interest and penalties.

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 first quarter of 2018, the Company received cash settlements for final resolution of the 2008 through 2010 Internal Revenue Service (“IRS”) audits. Ameriprise Financial’s audits are resolved through 2011. Ameriprise Financial’s 2012 and 2013 tax returns are at IRS appeals due to an unagreed issue. The IRS is currently auditing Ameriprise Financial’s U.S. income tax returns for 2014 and 2015. Ameriprise Financial’s or the Company’s state income tax returns are currently under examination by various jurisdictions for years ranging from 2005 through 2015.

Contingencies

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.

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 March 31, 2018 and December 31, 2017, the estimated liability was $14 million, and the related premium tax asset was $12 million. The expected period over which guaranty fund assessments will be made and the related tax credits recovered is not known.

⁽¹⁾ Revenues not included in the scope of the revenue from contracts with customers standard.

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 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. 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, Ameriprise Financial Services, Inc., 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 life 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 $54 million as of both March 31, 2018 and December 31, 2017.

Regulatory Requirements [Text Block]

Regulatory 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. 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, 2018, for certain derivative instruments used to economically hedge the interest rate exposure of certain variable annuity products that do not qualify for statutory hedge accounting. The permitted practice is intended to mitigate the impact to statutory surplus from the misalignment between variable annuity statutory reserves, which are not carried at fair value, and the fair value of derivatives used to economically hedge the interest rate exposure of non-life contingent living benefit guarantees. As of March 31, 2017 and December 31, 2017, application of this permitted practice resulted in an increase (decrease) to RiverSource Life Insurance Company’s statutory surplus of approximately $214 million and $(3) million, respectively.
