Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Business AXA Equitable Holdings, Inc. (“Holdings” and, collectively with its consolidated subsidiaries, the “Company”) is the holding company for a diversified financial services organization. In May 2017, AXA S.A. (“AXA”), a French holding company for the AXA Group, a worldwide leader in life, property and casualty and health insurance and asset management, announced its intention to pursue the sale of a minority stake in Holdings through an initial public offering (the “IPO”). On May 14, 2018 , Holdings completed the IPO in which AXA sold 157,837,500 shares of Holdings common stock to the public. Following the IPO, AXA owns approximately 71.9% of the outstanding common stock of Holdings. The Company conducts operations in four segments: Individual Retirement, Group Retirement, Investment Management and Research, and Protection Solutions. The Company’s management evaluates the performance of each of these segments independently. • The Individual Retirement segment offers a diverse suite of variable annuity products which are primarily sold to affluent and high net worth individuals saving for retirement or seeking retirement income. • The Group Retirement segment offers tax-deferred investment and retirement plans sponsored by educational entities, municipalities and not-for-profit entities as well as small and medium-sized businesses. • The Investment Management and Research segment provides diversified investment management, research and related solutions globally to a broad range of clients through three main client channels—Institutional, Retail and Private Wealth Management—and distributes its institutional research products and solutions through Bernstein Research Services. The Investment Management and Research segment reflects the business of AllianceBernstein Holding L.P. (“AB Holding”), AllianceBernstein L.P. (“ABLP”) and their subsidiaries (collectively, “AB”). • The Protection Solutions segment includes the Company’s life insurance and group employee benefits businesses. The life insurance business offers a variety of variable universal life, indexed universal life and term life products to help affluent and high net worth individuals, as well as small and medium-sized business owners, with their wealth protection, wealth transfer and corporate needs. Our group employee benefits business offers a suite of life, short- and long-term disability, dental and vision insurance products to small and medium-size businesses across the United States. The Company reports certain activities and items that are not included in our segments in Corporate and Other. Corporate and Other includes certain of our financing and investment expenses. It also includes: the AXA Advisors broker-dealer business, closed block of life insurance (the “Closed Block”), run-off variable annuity reinsurance business, run-off group pension business, run-off health business, benefit plans for our employees, certain strategic investments and certain unallocated items, including capital and related investments, interest expense and corporate expense. AB’s results of operations are reflected in the Investment Management and Research segment. Accordingly, Corporate and Other does not include any items applicable to AB. At March 31, 2018 and March 31, 2017 , the Company’s economic interest in AB was 46.5 % and 45.8% , respectively. At March 31, 2018 and March 31, 2017 , respectively, AXA and its subsidiaries’ economic interest in AB was 64.4% and 63.8% . In March 2018, AXA contributed the 0.5% minority interest in AXA Financial, Inc. (“AXA Financial”) to Holdings so that Holdings now owns 100% of AXA Financial. On April 23, 2018, Holdings entered into a Purchase Agreement (the “Purchase Agreement”) with Coliseum Reinsurance Company (“Coliseum”), an affiliate, relating to the purchase and sale of all of the units of limited partnership of ABLP (the “AB Units”) owned by Coliseum. Pursuant to the Purchase Agreement, Holdings purchased from Coliseum 8,160,000 AB Units owned by Coliseum at a purchase price of $26.54 per AB Unit. On April 23, 2018, Holdings entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with AXA Investment Managers S.A., an affiliate, relating to the purchase and sale of all of the issued and outstanding shares of common stock of AXA-IM Holding U.S., Inc. As a result of the transactions contemplated by the Stock Purchase Agreement, Holdings acquired beneficial ownership to the 41,934,582 AB Units owned by AXA-IM Holding U.S., Inc. As a result of these transactions, at April 30, 2018, the Company’s economic interest in AB was approximately 65.0% . The general partner of AB, AllianceBernstein Corporation (the “General Partner”), is a wholly-owned subsidiary of the Company. Because the General Partner has the authority to manage and control the business of AB, AB is consolidated in the Company’s financial statements. See Note 18 to the Notes to Consolidated Financial Statements for additional information on these subsequent events. Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Intercompany balances and transactions have been eliminated. In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The terms “ first quarter 2018 ” and “ first quarter 2017 ” refer to the three months ended March 31, 2018 and 2017 , respectively. The terms “ first three months of 2018 ” and “ first three months of 2017 ” refer to the three months ended March 31, 2018 and 2017 , respectively.

SIGNIFICANT ACCOUNTING POLICIES

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Adoption of New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance that revises the recognition criteria for revenue arising from contracts with customers to provide goods or services, except when those revenue streams are from insurance and investment contracts, leases, rights and obligations that are in the scope of certain financial instruments (i.e., derivative contracts) and guarantees other than product or service warranties, for which existing revenue recognition requirements are not superseded by this guidance. On January 1, 2018, the Company adopted the new revenue recognition guidance on a modified retrospective basis and is providing in its first quarter 2018 reporting the additional disclosures required by the new standard. Adoption of this new guidance did not change the amounts or timing of the Company’s revenue recognition for base investment management and advisory fees, distribution revenues, shareholder servicing revenues, and broker-dealer revenues. However, some performance-based fees and carried-interest distributions that prior to adoption were recognized when no risk of reversal remained, in certain instances under the new standard may be recognized earlier if it is probable that significant reversal will not occur. As a result, on January 1, 2018, the Company recognized a cumulative effect adjustment, net of tax, to increase opening equity attributable to Holdings and the noncontrolling interest by approximately $13 million and $19 million , respectively, reflecting the impact of carried-interest distributions previously received by AB of approximately $78 million , net of revenue sharing payments to investment team members of approximately $43 million , for which it is probable that significant reversal will not occur and for which incremental tax is provided at Holdings. In January 2016, the FASB issued new guidance related to the recognition and measurement of financial assets and financial liabilities. The new guidance primarily affects the accounting for equity investments, financial liabilities under the fair value option, and presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale (“AFS”) debt securities. The new guidance requires equity investments in unconsolidated entities, except those accounted for under the equity method, to be measured at fair value through earnings, thereby eliminating the AFS classification for equity securities with readily determinable fair values for which changes in fair value currently are reported in Accumulated Other Comprehensive Income (Loss) (“AOCI”). On January 1, 2018, the Company adopted the new recognition requirements on a modified retrospective basis for changes in the fair value of AFS equity securities, resulting in no material reclassification adjustment from AOCI to opening retained earnings for the net unrealized gains, net of tax, related to approximately $46 million common stock securities and eliminated their designation as AFS equity securities. The new guidance does not apply to FHLB common stock and prohibits such investments from being classified as equity securities subject to the new guidance. Accordingly, the Company has classified its investment in the FHLB common stock as other invested assets at March 31, 2018. The Company’s investment assets held in the form of equity interests in unconsolidated entities, such as limited partnerships and limited liability companies, including hedge funds, private equity funds, and real estate-related funds, generally are accounted for under the equity method and were not impacted by this new guidance. The Company does not currently report any of its financial liabilities under the fair value option. In March 2017, the FASB issued new guidance on the presentation of net periodic pension and post-retirement benefit costs that requires retrospective disaggregation of the service cost component from the other components of net benefit costs on the income statement. The service cost component is required to be presented with other employee compensation costs in “income from operations,” and the remaining components are to be reported separately outside of income from operations. While this standard did not change how net periodic pension and post-retirement benefit costs are measured, it limits the amount eligible for capitalization on a prospective basis to the service cost component. On January 1, 2018, the Company adopted the change in the income statement presentation utilizing the practical expedient for determining the historical components of net benefit costs, resulting in no material impact to the consolidated financial statements. In addition, no changes to the Company’s capitalization policies with respect to benefit costs resulted from the adoption of the new guidance. In May 2017, the FASB issued guidance on share-based payments. The amendment provides clarity intended to reduce diversity in practice and the cost and complexity of accounting for changes to the terms or conditions of share-based payment awards. The new guidance is effective for interim and annual periods beginning after December 15, 2017 and requires prospective application to awards modified on or after the date of adoption. Adoption of this amendment on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued new guidance to simplify elements of cash flow classification. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The new guidance is effective for interim and annual periods beginning after December 15, 2017 and requires application of a retrospective transition method. Adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Future Adoption of New Accounting Pronouncements In February 2018, the FASB issued new guidance that will permit, but not require, entities to reclassify to retained earnings tax effects “stranded” in AOCI resulting from the change in federal tax rate enacted by the Tax Cuts and Jobs Act (the “Tax Reform Act”) on December 22, 2017. An entity that elects this option must reclassify these stranded tax effects for all items in AOCI, including, but not limited to, AFS securities and employee benefits. Tax effects stranded in AOCI for other reasons, such as prior changes in tax law, may not be reclassified. While the new guidance provides entities the option to reclassify these amounts, new disclosures are required regardless of whether entities elect to do so. The new guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. Election can be made either to apply the new guidance retrospectively to each period in which the effect of the Tax Reform Act is recognized or in the period of adoption. Management currently is evaluating the options provided for adopting this guidance and the potential impacts on the Company’s consolidated financial statements. In August 2017, the FASB issued new guidance on accounting for hedging activities, intended to more closely align the financial statement reporting of hedging relationships to the economic results of an entity’s risk management activities. In addition, the new guidance makes certain targeted modifications to simplify the application of current hedge accounting guidance. The new guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early application permitted. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). All transition requirements and elections should be applied to derivatives positions and hedging relationships existing on the date of adoption. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In March 2017, the FASB issued guidance that requires certain premiums on callable debt securities to be amortized to the earliest call date and is intended to better align interest income recognition with the manner in which market participants price these instruments. The new guidance is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted and is to be applied on a modified retrospective basis. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In June 2016, the FASB issued new guidance related to the accounting for credit losses on financial instruments. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for annual periods beginning after December 15, 2018. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In February 2016, the FASB issued revised guidance to lease accounting that will require lessees to recognize on the balance sheet a “right-of-use” asset and a lease liability for virtually all lease arrangements, including those embedded in other contracts. The new lease accounting model will continue to distinguish between capital and operating leases. The current straight-line pattern for the recognition of rent expense on an operating lease is expected to remain substantially unchanged by the new guidance but instead will be comprised of amortization of the right-of-use asset and interest cost on the related lease obligation, thereby resulting in an income statement presentation similar to a financing arrangement or capital lease. Lessor accounting will remain substantially unchanged from the current model but has been updated to align with certain changes made to the lessee model. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The transition provisions require application on a modified retrospective approach at the beginning of the earliest comparative period presented in the financial statements (that is, January 1, 2017). Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing lease contracts and arrangements. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. Revenue Recognition Investment Management and Service Fees and Related Expenses Reported as Investment management and service fees in the Company’s consolidated statements of income (loss) are investment advisory and service fees, distribution revenues, and institutional research services revenues principally emerging from the Investment Management and Research segment. Also included are investment management and administrative service fees earned by AXA Equitable Funds Management Group, LLC (“AXA Equitable FMG”) and reported in the Retirement and Protection segments as well as certain asset-based fees associated with insurance contracts. Investment management, advisory, and service fees AB provides asset management services by managing customer assets and seeking to deliver returns to investors. Similarly, AXA Equitable FMG provides investment management and administrative services, such as fund accounting and compliance services, to AXA Premier VIP Trust (“VIP Trust”), EQ Advisors Trust (“EQAT”) and 1290 Funds as well as two private investment trusts established in the Cayman Islands, AXA Allocation Funds Trust and AXA Offshore Multimanager Funds Trust (collectively, the “Other AXA Trusts”). The contracts supporting these revenue streams create a distinct, separately identifiable performance obligation for each day the assets are managed for the performance of a series of services that are substantially the same and have the same pattern of transfer to the customer. Accordingly, these investment management, advisory, and administrative service base fees are recorded over time as services are performed and entitle the Company to variable consideration. Base fees, generally calculated as a percentage of assets under management (“AUM”), are recognized as revenue at month-end when the transaction price no longer is variable and the value of the consideration is determined. These fees are not subject to claw back and there is minimal probability that a significant reversal of the revenue recorded will occur. Certain investment advisory contracts of AB, including those associated with hedge funds or other alternative investments, provide for a performance-based fee (including carried interest), in addition to a base advisory fee, calculated either as a percentage of absolute investment results or a percentage of investment results in excess of a stated benchmark over a specified period of time. These performance-based fees are forms of variable consideration and, therefore, are excluded from the transaction price until it becomes probable there will not be significant reversal of the cumulative revenue recognized. At each reporting date, the Company evaluates constraining factors surrounding the variable consideration to determine the extent to which, if any, revenues associated with the performance-based fee can be recognized. Constraining factors impacting the amount of variable consideration included in the transaction price include contractual claw-back provisions, the length of time of the uncertainty, the number and range of possible amounts, the probability of significant fluctuations in fund’s market value, and the level in which the fund’s value exceeds the contractual threshold required to earn such a fee and the materiality of the amount being evaluated. Prior to adoption of the new revenue recognition guidance on January 1, 2018, the Company recognized performance-based fees at the end of the applicable measurement period when no risk of reversal remained, and carried-interest distributions received as deferred revenues until no risk of reversal remained. Sub-advisory and sub-administrative expenses associated with these services are calculated and recorded as the related services are performed in Other operating costs and expense in the consolidated statements of income (loss) as the Company is acting in a principal capacity in these transactions and, as such, reflects these revenues and expenses on a gross basis. Research services Research services revenue principally consists of brokerage transaction charges received by Sanford C. Bernstein & Co. LLC (“SCB LLC”) and Sanford C. Bernstein Limited (“SCBL”) for providing equity research services to institutional clients. Brokerage commissions for trade execution services and related expenses are recorded on a trade-date basis when the performance obligations are satisfied. Generally, the transaction price is agreed upon at the point of each trade and based upon the number of shares traded or the value of the consideration traded. Research revenues are recognized when the transaction price is quantified, collectability is assured, and significant reversal of such revenue is not probable. Distribution services Revenues from distribution services include fees received as partial reimbursement of expenses incurred in connection with the sale of certain AB sponsored mutual funds and the 1290 Funds and for the distribution primarily of EQAT and VIP Trust shares to separate accounts in connection with the sale of variable life and annuity contracts. The amount and timing of revenues recognized from performance of these distribution services often is dependent upon the contractual arrangements with the customer and the specific product sold as further described below. Most open-end management investment companies, such as U.S. funds and the EQAT and VIP Trusts and the 1290 Funds, have adopted a plan under Rule 12b-1 of the Investment Company Act that allows for certain share classes to pay out of assets, distribution and service fees for the distribution and sale of its shares (“12b-1 Fees”). These open-end management investment companies have such agreements with the Company, and the Company has selling and distribution agreements pursuant to which it pays sales commissions to the financial intermediaries that distribute the shares. These agreements may be terminated by either party upon notice (generally 30 days) and do not obligate the financial intermediary to sell any specific amount of shares. The Company records 12b-1 fees monthly based upon a percentage of the net asset value (“NAV”) of the funds. At month-end, the variable consideration of the transaction price is no longer constrained as the NAV can be calculated and the value of consideration is determined. These services are separate and distinct from other asset management services as the customer can benefit from these services independently of other services. The Company accrues the corresponding 12b-1 fees paid to sub-distributors monthly as the expenses are incurred. The Company is acting in a principal capacity in these transactions; as such, these revenues and expenses are recorded on a gross basis in the consolidated statements of income (loss). AB sponsored mutual funds offer back-end load shares in limited instances and charge the investor a contingent deferred sales charge (“CDSC”) if the investment is redeemed within a certain period. The variable consideration for these contracts is contingent upon the timing of the redemption by the investor and the value of the sales proceeds. Due to these constraining factors, the Company excludes the CDSC fee from the transaction price until the investor redeems the investment. Upon redemption, the cash consideration received for these contractual arrangements is recorded as a reduction of unamortized deferred sales commissions. AB’s Luxembourg subsidiary, the management company for most of its non-U.S. funds, earns a management fee which is accrued daily and paid monthly, at an annual rate, based on the average daily net assets of the fund. With respect to certain share classes, the management fee also may contain a component paid to distributors and other financial intermediaries and service providers to cover shareholder servicing and other administrative expenses (also referred to as an “All-in-Fee”). Based on the conclusion that asset management is distinct from distribution, the Company allocates a portion of the investment and advisory fee to distribution revenues for the servicing component based on standalone selling prices. Other revenues Also reported as Investment management and service fees in the Company’s consolidated statements of income (loss) are other revenues from contracts with customers, primarily consisting of shareholder servicing fees, mutual fund reimbursements, and other brokerage income. Shareholder services, including transfer agency, administration, and record-keeping are provided by AB to company-sponsored mutual funds. The consideration for these services is based on a percentage of the NAV of the fund or a fixed-fee based on the number of shareholder accounts being serviced. The revenues are recorded at month-end when the constraining factors involved with determining NAV or the numbers of shareholders’ accounts are resolved. Other income Revenues from contracts with customers reported as Other income in the Company’s consolidated statements of income (loss) primarily consist of advisory account fees and brokerage commissions from the Company’s subsidiary broker-dealer operations and sales commissions from the Company’s general agent for the distribution of non-affiliate insurers’ life insurance and annuity products. These revenues are recognized at month-end when constraining factors, such as AUM and product mix, are resolved and the transaction pricing no longer is variable such that the value of consideration can be determined. Contract assets and liabilities The Company applies the practical expedient for contracts that have an original duration of one year or less. Accordingly, the Company accrues the incremental costs of obtaining a contract when incurred and does not consider the time value of money. At March 31, 2018, there are no material balances of contract assets and contract liabilities; as such, no further disclosures are necessary. Accounting and Consolidation of VIEs A VIE must be consolidated by its primary beneficiary, which generally is defined as the party that has a controlling financial interest in the VIE. The Company is deemed to have a controlling financial interest in a VIE if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE or the right to receive income from the VIE that potentially could be significant to the VIE. For purposes of evaluating (ii) above, fees paid to the Company as a decision maker or service provider are excluded if the fees are compensation for services provided commensurate with the level of effort required to be performed and the arrangement includes only customary terms, conditions or amounts present in arrangements for similar services negotiated at arm’s length. If the Company has a variable interest in an entity that is determined not to be a VIE, the entity then is evaluated for consolidation under the voting interest entity (“VOE”) model. For limited partnerships and similar entities, the Company is deemed to have a controlling financial interest in a VOE, and would be required to consolidate the entity, if the Company owns a majority of the entity’s kick-out rights through voting limited partnership interests and other limited partners do not hold substantive participating rights (or other rights that would indicate that the Company does not control the entity). For entities other than limited partnerships, the Company is deemed to have a controlling financial interest in a VOE if it owns a majority voting interest in the entity. The analysis performed to identify variable interests held, determine whether entities are VIEs or VOEs, and evaluate whether the Company has a controlling financial interest in such entities requires the exercise of judgment and is updated on a continuous basis as circumstances change or new entities are developed. The primary beneficiary evaluation generally is performed qualitatively based on all facts and circumstances, including consideration of economic interests in the VIE held directly and indirectly through related parties and entities under common control, as well as quantitatively, as appropriate. At March 31, 2018 , the Company held approximately $1,137 million of investment assets in the form of equity interests issued by non-corporate legal entities determined under the new guidance to be VIEs, such as limited partnerships and limited liability companies, including hedge funds, private equity funds, and real estate-related funds. As an equity investor, the Company is considered to have a variable interest in each of these VIEs as a result of its participation in the risks and/or rewards these funds were designed to create by their defined portfolio objectives and strategies. Primarily through qualitative assessment, including consideration of related party interests or other financial arrangements, if any, the Company was not identified as primary beneficiary of any of these VIEs, largely due to its inability to direct the activities that most significantly impact their economic performance. Consequently, the Company continues to reflect these equity interests in the consolidated balance sheet as Other equity investments and to apply the equity method of accounting for these positions. The net assets of these non-consolidated VIEs are approximately $163,434 million , and the Company’s maximum exposure to loss from its direct involvement with these VIEs is the carrying value of its investment of $1,137 million at March 31, 2018 . Except for approximately $798 million of unfunded commitments at March 31, 2018 , the Company has no further economic interest in these VIEs in the form of guarantees, derivatives, credit enhancements or similar instruments and obligations. At March 31, 2018 , the Company consolidated one real estate joint venture for which it was identified as primary beneficiary under the VIE model. The consolidated entity is jointly owned by AXA Equitable Life Insurance Company (“AXA Equitable Life”) and AXA France and holds an investment in a real estate venture. Included in the Company’s consolidated balance sheet at March 31, 2018 , are total assets of $36 million related to this VIE, primarily resulting from the consolidated presentation of $36 million of real estate held for production of income. In addition, real estate held for production of income reflects $16 million as related to two non-consolidated joint ventures at March 31, 2018 . Included in the Company’s consolidated balance sheet at March 31, 2018 are assets of $2,447 million , liabilities of $1,219 million and redeemable non-controlling interest of $982 million associated with the consolidation of AB-sponsored investment funds under the VIE model. Also included in the Company’s consolidated balance sheets are assets of $135 million , liabilities of $4 million and redeemable non-controlling interest of $10 million from consolidation of AB-sponsored investment funds under the VOE model. The assets of these consolidated funds are presented within Other invested assets and cash and cash equivalents, and liabilities of these consolidated funds are presented with other liabilities on the face of the Company’s consolidated balance sheet at March 31, 2018 ; ownership interests not held by the Company relating to consolidated VIEs and VOEs are presented either as redeemable or non-redeemable noncontrolling interest, as appropriate. The Company is not required to provide financial support to these company-sponsored investment funds, and only the assets of such funds are available to settle each fund’s own liabilities. As of March 31, 2018 , the net assets of investment products sponsored by AB that are nonconsolidated VIEs are approximately $83.9 billion and the Company’s maximum exposure to loss from its direct involvement with these VIEs is its investment of $8 million at March 31, 2018 . The Company has no further commitments to or economic interest in these VIEs. Impact of the Tax Reform Act On December 22, 2017, President Trump signed into law the Tax Reform Act, a broad overhaul of the U.S. Internal Revenue Code that changes long-standing provisions governing the taxation of U.S. corporations, including life insurance companies. The Tax Reform Act reduces the federal corporate income tax rate to 21% beginning in 2018 and repeals the corporate alternative minimum tax (“AMT”) while keeping existing AMT credits. It also includes changes to the dividends received deduction (“DRD”), insurance reserves and tax DAC, and measures affecting our international operations, such as a one-time transitional tax on some of the accumulated earnings of our foreign subsidiaries (within our Investment Management and Research segment). As a result of the Tax Reform Act, our new effective tax rate is expected to be approximately 19% , driven mainly by the new federal corporate tax rate of 21% and the DRD benefit. We expect the Tax Reform Act to have both positive and negative impacts on our consolidated balance sheet. On the one hand, as a one-time effect, the lower tax rate resulted in a reduction to the value of our deferred tax assets. On the other hand, the Tax Reform Act repeals the corporate AMT and, subject to certain limitations, allows us to use our AMT credits going forward, which will result in a reduction of our tax liability. We expect the tax liability on the earnings of our foreign subsidiaries will decrease going forward. In 2017, we recorded a one-time estimated decrease to net income of $23 million due to the estimated transitional tax on some of the accumulated earnings of these subsidiaries. Overall, we expect the Tax Reform Act to have a net positive economic impact on us. At December 31, 2017, we recorded a provisional estimate of the income tax effects related to Tax Reform. During the period ended March 31, 2018, we have not recorded any changes to this estimate. We continue to evaluate this new and complicated piece of legislation, assess the magnitude of the various impacts and monitor potential regulatory changes related to this reform. Assumption Updates and Model Changes There were no assumption changes in the first quarters of 2018 or 2017. Revision of Prior Period Financial Statements During the first quarter of 2018, management identified an error in its previously issued financial statements related to a misclassification between interest credited and net derivative gains/losses. The impact of this error to the consolidated financial statements for the six months ended June 30, 2017, nine months ended September 30, 2017 and the years ended December 31, 2017 and 2016 was not considered to be material. In order to improve the consistency and comparability of the financial statements, management revised the consolidated statements of income (loss) and statements of cash flows to include the revisions discussed herein. See Note 17 to the Notes to Consolidated Financial Statements for details of the revisions.

The contractual maturities of AFS fixed maturities at March 31, 2018 are shown in the table below. Bonds not due at a single maturity date have been included in the table in the final year of maturity. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The following tables disclose the fair values and gross unrealized losses of the 1,411 issues at March 31, 2018 and the 752 issues at December 31, 2017 of fixed maturities that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position for the specified periods at the dates indicated: Less Than 12 Months 12 Months or Longer Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in millions) March 31, 2018: Fixed Maturity Securities: Public corporate $ 8,539 $ 263 $ 605 $ 35 $ 9,144 $ 298 Private corporate 2,457 63 660 44 3,117 107 U.S. Treasury, government and agency 3,129 81 4,325 425 7,454 506 States and political subdivisions 19 1 — — 19 1 Foreign governments 57 2 70 7 127 9 Residential mortgage-backed 145 2 76 1 221 3 Asset-backed 81 4 1 — 82 4 Redeemable preferred stock 116 2 12 2 128 4 Total $ 14,543 $ 418 $ 5,749 $ 514 $ 20,292 $ 932 December 31, 2017: Fixed Maturity Securities: Public corporate $ 2,123 $ 15 $ 690 $ 18 $ 2,813 $ 33 Private corporate 780 8 641 24 1,421 32 U.S. Treasury, government and agency 2,718 6 4,506 245 7,224 251 States and political subdivisions 20 — — — 20 — Foreign governments 11 — 73 5 84 5 Residential mortgage-backed 62 — 76 1 138 1 Asset-backed 15 1 12 — 27 1 Redeemable preferred stock 10 — 13 1 23 1 Total $ 5,739 $ 30 $ 6,011 $ 294 $ 11,750 $ 324 The Company’s investments in fixed maturity securities do not include concentrations of credit risk of any single issuer greater than 10% of the consolidated equity of the Company, other than securities of the U.S. government, U.S. government agencies, and certain securities guaranteed by the U.S. government. The Company maintains a diversified portfolio of corporate securities across industries and issuers and does not have exposure to any single issuer in excess of 0.5 % of total investments. The largest exposures to a single issuer of corporate securities held at March 31, 2018 and December 31, 2017 were $219 million and $207 million , respectively. Corporate high yield securities, consisting primarily of public high yield bonds, are classified as other than investment grade by the various rating agencies, i.e., a rating below Baa3/BBB- or the National Association of Insurance Commissioners (“NAIC”) designation of 3 (medium grade), 4 or 5 (below investment grade) or 6 (in or near default). At March 31, 2018 and December 31, 2017 , respectively, approximately $1,335 million and $1,372 million , or 3.1 % and 3.0% , of the $43,268 million and $45,068 million aggregate amortized cost of fixed maturities held by the Company were considered to be other than investment grade. These securities had net unrealized losses of $14 million and $5 million at March 31, 2018 and December 31, 2017 , respectively. At March 31, 2018 and December 31, 2017 , respectively, the $514 million and $294 million of gross unrealized losses of twelve months or more were concentrated in corporate and U.S. Treasury, government and agency securities. In accordance with the policy described in Note 2 , the Company concluded that an adjustment to income for OTTI for these securities was not warranted at either March 31, 2018 or 2017 . At March 31, 2018 and December 31, 2017 , the Company did not intend to sell the securities nor will it likely be required to dispose of the securities before the anticipated recovery of their remaining amortized cost basis. The Company does not originate, purchase or warehouse residential mortgages and is not in the mortgage servicing business. At March 31, 2018 , the carrying value of fixed maturities that were non-income producing for the twelve months preceding that date was $3 million . For the three months ended March 31, 2018 and 2017 , investment income is shown net of investment expenses of $19 million and $19 million respectively. At March 31, 2018 and December 31, 2017 , respectively, the fair values of the Company’s trading account securities were $14,919 million and $14,170 million , respectively. Also at March 31, 2018 and December 31, 2017 , trading securities included the General Account’s investment in Separate Accounts, which had carrying values of $49 million and $50 million , respectively. Net unrealized and realized gains (losses) on trading account equity securities are included in Net investment income (loss) in the Consolidated Statements of Income (Loss). The table below shows a breakdown of Net investment income from trading account securities during the three months ended March 31, 2018 and 2017 : Net Investment Income (Loss) from Trading Securities Three Months Ended March 31, 2018 2017 (in millions) Net investment gains (losses) recognized during the period on securities held at the end of the period $ (121 ) $ 87 Net investment gains (losses) recognized on securities sold during the period 1 4 Unrealized and realized gains (losses) on trading securities arising during the period (120 ) 91 Interest and dividend income from trading securities 76 63 Net investment income (loss) from trading securities $ (44 ) $ 154 Mortgage Loans The payment terms of mortgage loans may from time to time be restructured or modified. Mortgage loans on real estate are placed on nonaccrual status once management determines the collection of accrued interest is doubtful. Once mortgage loans on real estate are classified as nonaccrual loans, interest income is recognized under the cash basis of accounting and the resumption of the interest accrual would commence only after all past due interest has been collected or the mortgage loan on real estate has been restructured to where the collection of interest is considered likely. At March 31, 2018 and December 31, 2017 , the carrying values of commercial mortgage loans on real estate that had been classified as nonaccrual loans were $19 million and $19 million , respectively. Valuation Allowances for Mortgage Loans: Allowance for credit losses for mortgage loans for the first quarters of 2018 and 2017 are as follows: Three Months Ended March 31, 2018 2017 (in millions) Allowance for credit losses: Beginning balance, January 1, $ 8 $ 8 Charge-offs — — Recoveries (1 ) — Provision — — Ending balance, March 31, $ 7 $ 8 March 31, Individually Evaluated for Impairment $ 7 $ 8 There were no allowances for credit losses for agricultural mortgage loans for the first quarters of 2018 and 2017 . Real Estate: In March 2018, the Company sold its interest in two consolidated real estate joint ventures to AXA France for a total purchase price of approximately $143 million , which resulted in a pre-tax loss of $0.2 million and the reduction of $203 million of long-term debt on the Company’s balance sheet for the first quarter of 2018. The following tables provide information relating to the loan-to-value and debt service coverage ratios for commercial and agricultural mortgage loans at March 31, 2018 and December 31, 2017 . The values used in these ratio calculations were developed as part of the periodic review of the commercial and agricultural mortgage loan portfolio, which includes an evaluation of the underlying collateral value.

Derivatives and Offsetting Assets and Liabilities The Company uses derivatives as part of its overall asset/liability risk management primarily to reduce exposures to equity market and interest rate risks. Derivative hedging strategies are designed to reduce these risks from an economic perspective and are all executed within the framework of a Derivative Use Plan (“DUP”) approved by applicable states’ insurance law. Derivatives are generally not accounted for using hedge accounting, with the exception of Treasury Inflation-Protected Securities (“TIPS”), which is discussed further below. Operation of these hedging programs is based on models involving numerous estimates and assumptions, including, among others, mortality, lapse, surrender and withdrawal rates, election rates, fund performance, market volatility and interest rates. A wide range of derivative contracts are used in these hedging programs, including exchange traded equity, currency and interest rate futures contracts, total return and/or other equity swaps, interest rate swap and floor contracts, bond and bond-index total return swaps, swaptions, variance swaps and equity options credit and foreign exchange derivatives as well as bond and repo transactions to support the hedging. The derivative contracts are collectively managed in an effort to reduce the economic impact of unfavorable changes in guaranteed benefits’ exposures attributable to movements in capital markets. In addition, as part of our hedging strategy the Company holds static hedge positions to maintain a target asset level for all variable annuity products at or above a CTE98 level under most economic scenarios (CTE is a statistical measure of tail risk which quantifies the total asset requirement to sustain a loss if an event outside a given probability level has occurred. CTE 98 denotes the financial resources a company would need to cover the average of the worst 2% of scenarios). Derivatives utilized to hedge exposure to Variable Annuities with Guarantee Features The Company has issued and continues to offer variable annuity products with variable annuity guaranteed benefits (“GMxB”), including guaranteed minimum living benefits (“GMLBs”) (such as guaranteed minimum income benefits (“GMIBs”), guaranteed minimum withdrawal benefits (“GMWBs”) and guaranteed minimum accumulation benefits (“GMABs” ), and guaranteed minimum death benefits (“GMDBs”) (inclusive of return of premium death benefit guarantees). The risk associated with the GMDB feature is that under-performance of the financial markets could result in GMDB benefits, in the event of death, being higher than what accumulated policyholders’ account balances would support. The risk associated with the GMIB feature is that under-performance of the financial markets could result in the present value of GMIB, in the event of annuitization, being higher than what accumulated policyholders’ account balances would support, taking into account the relationship between current annuity purchase rates and the GMIB guaranteed annuity purchase rates. The risk associated with products that have a GMxB derivative features liability is that under-performance of the financial markets could result in the GMxB derivative features’ benefits being higher than what accumulated policyholders’ account balances would support. For GMxB features, the Company retains certain risks including basis, credit spread and some volatility risk and risk associated with actual versus expected actuarial assumptions for mortality, lapse and surrender, withdrawal and policyholder election rates, among other things. The derivative contracts are managed to correlate with changes in the value of the GMxB features that result from financial markets movements. A portion of exposure to realized equity volatility is hedged using equity options and variance swaps and a portion of exposure to credit risk is hedged using total return swaps on fixed income indices. Additionally, the Company is party to total return swaps for which the reference U.S. Treasury securities are contemporaneously purchased from the market and sold to the swap counterparty. As these transactions result in a transfer of control of the U.S. Treasury securities to the swap counterparty, the Company derecognizes these securities with consequent gain or loss from the sale. The Company has also purchased reinsurance contracts to mitigate the risks associated with GMDB features and the impact of potential market fluctuations on future policyholder elections of GMIB features contained in certain annuity contracts issued by the Company. The Company has implemented static hedge positions to maintain a target asset level for all variable annuities at a CTE98 level under most scenarios, and at a CTE95 level in extreme scenarios. This program was implemented beginning in December 2017. Derivatives used to hedge crediting rate exposure on SCS, SIO, MSO and IUL products/investment options The Company hedges crediting rates in the Structured Capital Strategies (“SCS”) variable annuity, Structured Investment Option in the EQUI-VEST variable annuity series (“SIO”), Market Stabilizer Option (“MSO”) in the variable life insurance products and Indexed Universal Life (“IUL”) insurance products. These products permit the contract owner to participate in the performance of an index, ETF or commodity price movement up to a cap for a set period of time. They also contain a protection feature, in which the Company will absorb, up to a certain percentage, the loss of value in an index, ETF or commodity price, which varies by product segment. In order to support the returns associated with these features, the Company enters into derivative contracts whose payouts, in combination with fixed income investments, emulate those of the index, ETF or commodity price, subject to caps and buffers without any basis risk due to market exposures, thereby substantially reducing any exposure to market-related earnings volatility. Derivatives used for General Account Investment Portfolio The Company maintains a strategy in its General Account investment portfolio to replicate the credit exposure of fixed maturity securities otherwise permissible for investment under its investment guidelines through the sale of credit default swaps (“CDSs”). Under the terms of these swaps, the Company receives quarterly fixed premiums that, together with any initial amount paid or received at trade inception, replicate the credit spread otherwise currently obtainable by purchasing the referenced entity’s bonds of similar maturity. These credit derivatives generally have remaining terms of five years or less and are recorded at fair value with changes in fair value, including the yield component that emerges from initial amounts paid or received, reported in Net investment income (loss). The Company manages its credit exposure taking into consideration both cash and derivatives based positions and selects the reference entities in its replicated credit exposures in a manner consistent with its selection of fixed maturities. In addition, the Company generally transacts the sale of CDSs in single name reference entities of investment grade credit quality and with counterparties subject to collateral posting requirements. If there is an event of default by the reference entity or other such credit event as defined under the terms of the swap contract, the Company is obligated to perform under the credit derivative and, at the counterparty’s option, either pay the referenced amount of the contract less an auction-determined recovery amount or pay the referenced amount of the contract and receive in return the defaulted or similar security of the reference entity for recovery by sale at the contract settlement auction. To date, there have been no events of default or circumstances indicative of deterioration in the credit quality of the named referenced entities to require or suggest that the Company will have to perform under these CDSs. The maximum potential amount of future payments the Company could be required to make under these credit derivatives is limited to the par value of the referenced securities which is the dollar or euro-equivalent of the derivative notional amount. The Standard North American CDS Contract (“SNAC”) or Standard European Corporate Contract (“STEC”) under which the Company executes these CDS sales transactions does not contain recourse provisions for recovery of amounts paid under the credit derivative. The Company purchased 30-year TIPS and other sovereign bonds, inflation linked and non-inflation linked, as General Account investments and enters into asset or cross-currency basis swaps, to result in payment of the given bond’s coupons and principal at maturity in the bond’s specified currency to the swap counterparty in return for fixed dollar amounts. These swaps, when considered in combination with the bonds, together result in a net position that is intended to replicate a dollar-denominated fixed-coupon cash bond with a yield higher than a term-equivalent U.S. Treasury bond. At March 31, 2018 and December 31, 2017 , the Company’s unrealized gains (losses) related to this program were $(88) million and $(86) million , respectively, and reported in AOCI. The Company implemented a strategy to hedge a portion of the credit exposure in its General Account investment portfolio by buying protection through a swap. These are swaps on the “super senior tranche” of the investment grade CDX index. Under the terms of these swaps, the Company pays quarterly fixed premiums that, together with any initial amount paid or received at trade inception, serve as premiums paid to hedge the risk arising from multiple defaults of bonds referenced in the CDX index. These credit derivatives have terms of five years or less and are recorded at fair value with changes in fair value, including the yield component that emerges from initial amounts paid or received, reported in Net derivative gains (losses). In 2016, the Company implemented a program to mitigate its duration gap using total return swaps for which the reference U.S. Treasury securities are sold to the swap counterparty under arrangements economically similar to repurchase agreements. As these transactions result in a transfer of control of the U.S. Treasury securities to the swap counterparty, the Company derecognizes these securities with consequent gain or loss from the sale. Under this program the Company derecognized approximately $3,905 million U.S. Treasury securities for which the Company received proceeds of approximately $3,906 million at inception of the total return swap contract. Under the terms of these swaps, the Company retains ongoing exposure to the total returns of the underlying U.S. Treasury securities in exchange for a financing cost. At March 31, 2018 , the aggregate fair value of U.S. Treasury securities derecognized under this program was approximately $3,673 million . Reported in Other invested assets in the Company’s balance sheet at March 31, 2018 is approximately $16 million , representing the fair value of the total return swap contracts. Derivatives used to hedge currency fluctuations on affiliated loans The Company uses foreign exchange derivatives to reduce exposure to currency fluctuations that may arise from non-U.S.-dollar denominated financial instruments. The Company has currency swap contracts with AXA to hedge foreign exchange exposure from affiliated loans. The tables below present quantitative disclosures about the Company’s derivative instruments, including those embedded in other contracts required to be accounted for as derivative instruments.

The March 31, 2018 values for direct variable annuity contracts in-force on such date with GMDB and GMIB features are presented in the following table. For contracts with the GMDB feature, the net amount at risk in the event of death is the amount by which the GMDB exceed related account values. For contracts with the GMIB feature, the net amount at risk in the event of annuitization is the amount by which the present value of the GMIB benefits exceeds related account values, taking into account the relationship between current annuity purchase rates and the GMIB guaranteed annuity purchase rates. Since variable annuity contracts with GMDB guarantees may also offer GMIB guarantees in the same contract, the GMDB and GMIB amounts listed are not mutually exclusive: Direct Variable Annuity Contract Values Return of Premium Ratchet Roll-Up Combo Total (Dollars in millions) GMDB: Account values invested in: General Account $ 13,848 $ 107 $ 64 $ 194 $ 14,213 Separate Accounts $ 45,136 $ 9,319 $ 3,381 $ 34,668 $ 92,504 Net amount at risk, gross $ 186 $ 117 $ 2,016 $ 16,388 $ 18,707 Net amount at risk, net of amounts reinsured $ 186 $ 111 $ 1,378 $ 16,388 $ 18,063 Average attained age of policyholders 51 67 73 68 55 Percentage of policyholders over age 70 9.7 % 40.9 % 63.7 % 47.4 % 18.3 % Range of contractually specified interest rates N/A N/A 3%-6% 3%-6.5% 3%-6.5% GMIB: Account values invested in: General Account N/A N/A $ 24 $ 285 $ 309 Separate Accounts N/A N/A $ 20,855 $ 39,604 $ 60,459 Net amount at risk, gross N/A N/A $ 883 $ 6,322 $ 7,205 Net amount at risk, net of amounts reinsured N/A N/A $ 268 $ 5,738 $ 6,006 Average attained age of policyholders N/A N/A 70 69 69 Weighted average years remaining until annuitization N/A N/A 1.7 0.7 0.8 Range of contractually specified interest rates N/A N/A 3%-6% 3%-6.5% 3%-6.5% The March 31, 2018 values for assumed variable annuity contracts in force on such date with GMDB and GMIB features are presented in the following table: Assumed Variable Annuity Contract Values Return of Premium Ratchet Roll-Up Combo Total (Dollars in millions) GMDB: Reinsured Account values $ 1,023 $ 5,849 $ 302 $ 1,879 $ 9,053 Net amount at risk assumed $ 7 $ 314 $ 24 $ 321 $ 666 Average attained age of policyholders 67 72 77 75 72 Percentage of policyholders over age 70 41.4 % 60.8 % 76.6 % 74.2 % 61.9 % Range of contractually specified interest rates N/A N/A 3%-10% 5%-10% 3%-10% GMIB: Reinsured Account values $ 978 $ 52 $ 277 $ 1,338 $ 2,645 Net amount at risk assumed $ 2 $ — $ 38 $ 215 $ 255 Average attained age of policyholders 71 74 71 68 70 Percentage of policyholders over age 70 61.6 % 63.7 % 55.9 % 48.1 % 54.2 % Range of contractually specified interest rates (1) N/A N/A 3.3%-6.5% 6%-6% 3.3%-6.5% (1) In general, for policies with the highest contractual interest rate shown ( 10% ), the rate applied only for the first 10 years after issue, which have now elapsed. B) Separate Account Investments by Investment Category Underlying GMDB and GMIB Features The total account values of variable annuity contracts with GMDB and GMIB features include amounts allocated to the guaranteed interest option, which is part of the General Account and variable investment options that invest through Separate Accounts in variable insurance trusts. The following table presents the aggregate fair value of assets, by major investment category, held by Separate Accounts that support variable annuity contracts with GMDB and GMIB guarantees. The investment performance of the assets impacts the related account values and, consequently, the net amount of risk associated with the GMDB and GMIB benefits and guarantees. Because variable annuity contracts offer both GMDB and GMIB features, GMDB and GMIB amounts are not mutually exclusive.

C) Hedging Programs for GMDB, GMIB, GIB and Other Features Beginning in 2003, the Company established a program intended to hedge certain risks associated first with the GMDB feature and, beginning in 2004, with the GMIB feature of the Accumulator series of variable annuity products. The program has also been extended to cover other guaranteed benefits as they have been made available. This program utilizes derivative contracts, such as exchange-traded equity, currency and interest rate futures contracts, total return and/or equity swaps, interest rate swap and floor contracts, swaptions, variance swaps as well as equity options, that collectively are managed in an effort to reduce the economic impact of unfavorable changes in guaranteed benefits’ exposures attributable to movements in the capital markets. At the present time, this program hedges certain economic risks on products sold from 2001 forward, to the extent such risks are not externally reinsured. At March 31, 2018 , the total account value and net amount at risk of the hedged variable annuity contracts were $68,663 million and $17,102 million , respectively, with the GMDB feature and $57,781 million and $ $7,236 million , respectively, with the GMIB and GIB feature. A hedge program is also used to manage certain capital markets risks associated with the products the Company has assumed that have GMDB and GMIB features. At March 31, 2018 , the total account value and net amount at risk of the hedged assumed variable annuity contracts were $9,053 million and $666 million , respectively, with the GMDB feature and $2,645 million and $255 million , respectively, with the GMIB feature. These programs do not qualify for hedge accounting treatment. Therefore, gains (losses) on the derivatives contracts used in these programs, including current period changes in fair value, are recognized in net investment income (loss) in the period in which they occur, and may contribute to income (loss) volatility. D) Variable and Interest-Sensitive Life Insurance Policies - NLG The NLG feature contained in variable and interest-sensitive life insurance policies keeps them in force in situations where the policy value is not sufficient to cover monthly charges then due. The NLG remains in effect so long as the policy meets a contractually specified premium funding test and certain other requirements. The following table summarizes the NLG liabilities reflected in the General Account in Future policy benefits and other policyholders’ liabilities, the related reinsurance reserve ceded, reflected in Amounts due from reinsurers and deferred cost of reinsurance, reflected in Other assets in the Consolidated balance sheets: Direct Liability (1) (in millions) Balance at January 1, 2018 $ 686 Paid Guaranteed Benefits (8 ) Other changes in reserves 26 Balance at March 31, 2018 $ 704 Balance at January 1, 2017 $ 1,307 Other changes in reserves 4 Balance at March 31, 2017 $ 1,311 (1) There were no amounts of reinsurance ceded in any period presented.

Insurance [Abstract]
REINSURANCE AGREEMENTS	REINSURANCE AGREEMENTS Effective February 1, 2018, AXA Equitable Life entered into a coinsurance reinsurance agreement (the “Coinsurance Agreement”) to cede 90% of its single premium deferred annuities (SPDA) products issued between 1978-2001 and its Guaranteed Growth Annuity (GGA) single premium deferred annuity products issued between 2001-2014. As a result of this agreement, AXA Equitable Life transferred securities with a market value of $604 million and cash of $31 million to equal the statutory reserves of approximately $635 million . As the risks transferred by AXA Equitable Life to the reinsurer under the Coinsurance Agreement are not considered insurance risks and therefore do not qualify for reinsurance accounting, AXA Equitable Life applied deposit accounting. Accordingly, AXA Equitable Life recorded the transferred assets of $635 million as a deposit asset recorded in Other assets, net of the ceding commissions paid to the reinsurer.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance established a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value, and identifies three levels of inputs that may be used to measure fair value: Level 1 Unadjusted quoted prices for identical instruments in active markets. Level 1 fair values generally are supported by market transactions that occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar instruments, quoted prices in markets that are not active, and inputs to model-derived valuations that are directly observable or can be corroborated by observable market data. Level 3 Unobservable inputs supported by little or no market activity and often requiring significant management judgment or estimation, such as an entity’s own assumptions about the cash flows or other significant components of value that market participants would use in pricing the asset or liability. The Company uses unadjusted quoted market prices to measure the fair value of instruments that are actively traded in financial markets. In cases where quoted market prices are not available, fair values are measured using present value or other valuation techniques. The fair value determinations are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of the timing and amount of expected future cash flows and the credit standing of counterparties. Such adjustments do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument, nor do they consider the tax impact of the realization of unrealized gains or losses. In many cases, the fair value cannot be substantiated by direct comparison to independent markets, nor can the disclosed value be realized in immediate settlement of the instrument. Management is responsible for the determination of the value of investments carried at fair value and the supporting methodologies and assumptions. Under the terms of various service agreements, the Company often utilizes independent valuation service providers to gather, analyze, and interpret market information and derive fair values based upon relevant methodologies and assumptions for individual securities. These independent valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested. As further described below with respect to specific asset classes, these inputs include, but are not limited to, market prices for recent trades and transactions in comparable securities, benchmark yields, interest rate yield curves, credit spreads, quoted prices for similar securities, and other market-observable information, as applicable. Specific attributes of the security being valued also are considered, including its term, interest rate, credit rating, industry sector, and when applicable, collateral quality and other security- or issuer-specific information. When insufficient market observable information is available upon which to measure fair value, the Company either will request brokers knowledgeable about these securities to provide a non-binding quote or will employ internal valuation models. Fair values received from independent valuation service providers and brokers and those internally modeled or otherwise estimated are assessed for reasonableness. Assets and liabilities measured at fair value on a recurring basis are summarized below. At March 31, 2018 and December 31, 2017 , no assets were required to be measured at fair value on a non-recurring basis. Fair value measurements are required on a non-recurring basis for certain assets, including goodwill and mortgage loans on real estate, only when an OTTI or other event occurs. When such fair value measurements are recorded, they must be classified and disclosed within the fair value hierarchy. The Company recognizes transfers between valuation levels at the beginning of the reporting period. Fair Value Measurements at March 31, 2018 Level 1 Level 2 Level 3 Total (in millions) Assets Investments Fixed maturities, available-for-sale: Public Corporate $ — $ 18,581 $ 135 $ 18,716 Private Corporate — 6,286 1,118 7,404 U.S. Treasury, government and agency — 14,653 — 14,653 States and political subdivisions — 438 39 477 Foreign governments — 419 — 419 Residential mortgage-backed (1) — 627 — 627 Asset-backed (2) — 135 540 675 Redeemable preferred stock 180 333 — 513 Subtotal 180 41,472 1,832 43,484 Other equity investments 13 — 34 47 Trading securities 448 14,427 44 14,919 Other invested assets: Short-term investments — 854 — 854 Assets of consolidated VIEs/VOEs 1,691 291 32 2,014 Swaps — 356 — 356 Credit Default Swaps — 29 — 29 Options — 1,939 — 1,939 Subtotal 1,691 3,469 32 5,192 Cash equivalents 4,894 — — 4,894 Segregated securities — 1,025 — 1,025 GMIB reinsurance contract asset — — 1,734 1,734 Separate Accounts’ assets 118,466 2,845 357 121,668 Total Assets $ 125,692 $ 63,238 $ 4,033 $ 192,963 Liabilities Other invested liabilities GMxB derivative features’ liability $ — $ — $ 3,977 $ 3,977 SCS, SIO, MSO and IUL indexed features’ liability — 1,683 — 1,683 Liabilities of consolidated VIEs/VOEs 1,190 18 — 1,208 Contingent payment arrangements — — 14 14 Total Liabilities $ 1,190 $ 1,701 $ 3,991 $ 6,882 (1) Includes publicly traded agency pass-through securities and collateralized obligations.

At March 31, 2018 and December 31, 2017 , respectively, the fair value of public fixed maturities is approximately $35,131 million and $38,762 million or approximately 18.5% and 20.0% of the Company’s total assets measured at fair value on a recurring basis (excluding GMIB reinsurance contracts and segregated securities measured at fair value on a recurring basis). The fair values of the Company’s public fixed maturity securities are generally based on prices obtained from independent valuation service providers and for which the Company maintains a vendor hierarchy by asset type based on historical pricing experience and vendor expertise. Although each security generally is priced by multiple independent valuation service providers, the Company ultimately uses the price received from the independent valuation service provider highest in the vendor hierarchy based on the respective asset type, with limited exception. To validate reasonableness, prices also are internally reviewed by those with relevant expertise through comparison with directly observed recent market trades. Consistent with the fair value hierarchy, public fixed maturity securities validated in this manner generally are reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. If the pricing information received from independent valuation service providers is not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process in accordance with the terms of the respective independent valuation service provider agreement. If as a result it is determined that the independent valuation service provider is able to reprice the security in a manner agreed as more consistent with current market observations, the security remains within Level 2. Alternatively, a Level 3 classification may result if the pricing information then is sourced from another vendor, non-binding broker quotes, or internally-developed valuations for which the Company’s own assumptions about market-participant inputs would be used in pricing the security. At March 31, 2018 and December 31, 2017 , respectively, the fair value of private fixed maturities is approximately $8,353 million and $8,179 million or approximately 4.4% and 4.2% of the Company’s total assets measured at fair value on a recurring basis. The fair values of the Company’s private fixed maturities are determined from prices obtained from independent valuation service providers. Prices not obtained from an independent valuation service provider are determined by using a discounted cash flow model or a market comparable company valuation technique. In certain cases, these models use observable inputs with a discount rate based upon the average of spread surveys collected from private market intermediaries who are active in both primary and secondary transactions, taking into account, among other factors, the credit quality and industry sector of the issuer and the reduced liquidity associated with private placements. Generally, these securities have been reflected within Level 2. For certain private fixed maturities, the discounted cash flow model or a market comparable company valuation technique may also incorporate unobservable inputs, which reflect the Company’s own assumptions about the inputs market participants would use in pricing the asset. To the extent management determines that such unobservable inputs are significant to the fair value measurement of a security, a Level 3 classification generally is made. As disclosed in Note 3 , at March 31, 2018 and December 31, 2017 , respectively, the net fair value of freestanding derivative positions is approximately 44.8 % and 42.9% of Other invested assets measured at fair value on a recurring basis, with a value of $2,324 million and $2,258 million . The fair values of the Company’s derivative positions are generally based on prices obtained either from independent valuation service providers or derived by applying market inputs from recognized vendors into industry standard pricing models. The majority of these derivative contracts are traded in the OTC derivative market and are classified in Level 2. The fair values of derivative assets and liabilities traded in the OTC market are determined using quantitative models that require use of the contractual terms of the derivative instruments and multiple market inputs, including interest rates, prices, and indices to generate continuous yield or pricing curves, including overnight index swap (“OIS”) curves, and volatility factors, which then are applied to value the positions. The predominance of market inputs is actively quoted and can be validated through external sources or reliably interpolated if less observable. If the pricing information received from independent valuation service providers is not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process in accordance with the terms of the respective independent valuation service provider agreement. If as a result it is determined that the independent valuation service provider is able to reprice the derivative instrument in a manner agreed as more consistent with current market observations, the position remains within Level 2. Alternatively, a Level 3 classification may result if the pricing information then is sourced from another vendor, non-binding broker quotes, or internally-developed valuations for which the Company’s own assumptions about market-participant inputs would be used in pricing the security. At March 31, 2018 and December 31, 2017 , respectively, investments classified as Level 1 comprise approximately 66.1 % and 64.9% of assets measured at fair value on a recurring basis and primarily include redeemable preferred stock, trading securities, cash equivalents and Separate Account assets. Fair value measurements classified as Level 1 include exchange-traded prices of fixed maturities, equity securities and derivative contracts, and net asset values for transacting subscriptions and redemptions of mutual fund shares held by Separate Accounts. Cash equivalents classified as Level 1 include money market accounts, overnight commercial paper and highly liquid debt instruments purchased with an original maturity of three months or less, and are carried at cost as a proxy for fair value measurement due to their short-term nature. At March 31, 2018 and December 31, 2017 , respectively, investments classified as Level 2 comprise approximately 32.7 % and 34.0% of assets measured at fair value on a recurring basis and primarily include U.S. government and agency securities and certain corporate debt securities, such as public and private fixed maturities. As market quotes generally are not readily available or accessible for these securities, their fair value measures are determined utilizing relevant information generated by market transactions involving comparable securities and often are based on model pricing techniques that effectively discount prospective cash flows to present value using appropriate sector-adjusted credit spreads commensurate with the security’s duration, also taking into consideration issuer-specific credit quality and liquidity. Segregated securities classified as Level 2 are U.S. Treasury bills segregated by AB in a special reserve bank custody account for the exclusive benefit of brokerage customers, as required by Rule 15c3-3 of the Exchange Act and for which fair values are based on quoted yields in secondary markets. Observable inputs generally used to measure the fair value of securities classified as Level 2 include benchmark yields, reported secondary trades, issuer spreads, benchmark securities and other reference data. Additional observable inputs are used when available, and as may be appropriate, for certain security types, such as prepayment, default, and collateral information for the purpose of measuring the fair value of mortgage- and asset-backed securities. At March 31, 2018 and December 31, 2017 , respectively, approximately $ 641 million and $875 million of AAA-rated mortgage- and asset-backed securities are classified as Level 2 for which the observability of market inputs to their pricing models is supported by sufficient, albeit more recently contracted, market activity in these sectors. Certain Company products such as the SCS and EQUI-VEST variable annuity product, and in the MSO fund available in some life contracts offer investment options which permit the contract owner to participate in the performance of an index, ETF or commodity price. These investment options, which depending on the product and on the index selected can currently have 1, 3, 5, or 6 year terms, provide for participation in the performance of specified indices, ETF or commodity price movement up to a segment-specific declared maximum rate. Under certain conditions that vary by product, e.g. holding these segments for the full term, these segments also shield policyholders from some or all negative investment performance associated with these indices, ETF or commodity prices. These investment options have defined formulaic liability amounts, and the current values of the option component of these segment reserves are accounted for as Level 2 embedded derivatives. The fair values of these embedded derivatives are based on data obtained from independent valuation service providers. At March 31, 2018 and December 31, 2017 , respectively, investments classified as Level 3 comprise approximately 1.2 % and 1.1% of assets measured at fair value on a recurring basis and primarily include corporate debt securities, such as private fixed maturities. Determinations to classify fair value measures within Level 3 of the valuation hierarchy generally are based upon the significance of the unobservable factors to the overall fair value measurement. Included in the Level 3 classification at March 31, 2018 and December 31, 2017 , respectively, were approximately $ 95 million and $97 million of fixed maturities with indicative pricing obtained from brokers that otherwise could not be corroborated to market observable data. The Company applies various due diligence procedures, as considered appropriate, to validate these non-binding broker quotes for reasonableness, based on its understanding of the markets, including use of internally-developed assumptions about inputs a market participant would use to price the security. In addition, approximately $ 540 million and $598 million of mortgage- and asset-backed securities are classified as Level 3 at March 31, 2018 and December 31, 2017 , respectively. The Company also issues certain benefits on its variable annuity products that are accounted for as derivatives and are also considered Level 3. The GMIBNLG feature allows the policyholder to receive guaranteed minimum lifetime annuity payments based on predetermined annuity purchase rates applied to the contract’s benefit base if and when the contract account value is depleted and the NLG feature is activated. The GMWB feature allows the policyholder to withdraw at minimum, over the life of the contract, an amount based on the contract’s benefit base. The GWBL feature allows the policyholder to withdraw, each year for the life of the contract, a specified annual percentage of an amount based on the contract’s benefit base. The GMAB feature increases the contract account value at the end of a specified period to a GMAB base. The GIB feature provides a lifetime annuity based on predetermined annuity purchase rates if and when the contract account value is depleted. This lifetime annuity is based on predetermined annuity purchase rates applied to a GIB base. Level 3 also includes the GMIB reinsurance contract asset’s which are accounted for as derivative contracts. The GMIB reinsurance contract asset and liabilities’ fair value reflects the present value of reinsurance premiums and recoveries and risk margins over a range of market consistent economic scenarios while GMxB derivative features liability reflects the present value of expected future payments (benefits) less fees, adjusted for risk margins and nonperformance risk, attributable to GMxB derivative features’ liability over a range of market-consistent economic scenarios. The valuations of the GMIB reinsurance contract asset and GMxB derivative features liability incorporate significant non-observable assumptions related to policyholder behavior, risk margins and projections of equity separate account funds. The credit risks of the counterparty and of the Company are considered in determining the fair values of its GMIB reinsurance contract asset and GMxB derivative features liability positions, respectively, after taking into account the effects of collateral arrangements. Incremental adjustment to the swap curve for non-performance risk is made to the fair values of the GMIB reinsurance contract asset and liabilities and GMIBNLG feature to reflect the claims-paying ratings of counterparties and the Company. Equity and fixed income volatilities were modeled to reflect current market volatilities. Due to the unique, long duration of the GMIBNLG feature, adjustments were made to the equity volatilities to remove the illiquidity bias associ ated with the longer tenors and risk margins were applied to the non-capital markets inputs to the GMIBNLG valuations. After giving consideration to collateral arrangements, the Company reduced the fair value of its GMIB reinsurance contract asset by $12 million and $8 million at March 31, 2018 and December 31, 2017 , respectively, to recognize incremental counterparty non-performance risk and reduced the fair value of its GMIB reinsurance contract liabilities by $24 million and $24 million at March 31, 2018 and December 31, 2017 , respectively to recognize its own incremental non-performance risk. Lapse rates are adjusted at the contract level based on a comparison of the actuarially calculated guaranteed values and the current policyholder account value, which include other factors such as considering surrender charges. Generally, lapse rates are assumed to be lower in periods when a surrender charge applies. A dynamic lapse function reduces the base lapse rate when the guaranteed amount is greater than the account value as in the money contracts are less likely to lapse. For valuing the embedded derivative, lapse rates vary throughout the period over which cash flows are projected. Th e Company’s Level 3 liabilities include contingent payment arrangements associated with acquisitions in 2010, 2013, 2014 and 2016 by AB. At each reporting date, AB estimates the fair values of the contingent consideration expected to be paid based upon probability-weighted AUM and revenue projections, using unobservable market data inputs, which are included in Level 3 of the valuation hierarchy. The Company’s Level 3 liabilities also include contingent payment arrangements associated with a Renewal Rights Agreement (the “Renewal Rights Agreement”) that transitions certain group employee benefits policies beginning January 1, 2017 from an insurer exiting such business to MONY Life Insurance Company of America (“MLOA”). The fair value of the contingent payments liability associated with this transaction is measured and adjusted each reporting period through final settlement using projected premiums from these policies, net of potential surrenders and terminations, and applying a risk-adjusted discount factor ( 7.0% at March 31, 2018 ) to the resulting cash flows. As of March 31, 2018 and December 31, 2017 , the Company’s consolidated VIEs/VOEs hold $32 million and $27 million , respectively of investments that are classified as Level 3 primarily consist of corporate bonds that are vendor priced with no ratings available, bank loans, non-agency collateralized mortgage obligations and asset-backed securities. In the first three months of 2018 , AFS fixed maturities with fair values of $16 million were transferred out of Level 3 and into Level 2 principally due to the availability of trading activity or market observable inputs to measure and validate their fair values. In addition, AFS fixed maturities with fair value of $67 million were transferred from Level 2 into the Level 3 classification. These transfers in the aggregate represent approximately 0.5% of total equity at March 31, 2018 . In the first three months of 2017 , $0 million AFS fixed maturities were transferred out of Level 3 and into Level 2 principally due to the availability of trading activity or market observable inputs to measure and validate their fair values. In addition, AFS fixed maturities with fair value of $24 million were transferred from Level 2 into the Level 3 classification. These transfers in the aggregate represent approximately 0.2% of total equity at March 31, 2017 .

The fair value measurements of these Level 3 investments comprise approximately 47.3 % and 44.0% of total assets classified as Level 3 and represent only 0.6 % and 0.5% of total assets measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017 , respectively. These investments primarily consist of certain privately placed debt securities with limited trading activity, including residential mortgage- and asset-backed instruments, and their fair values generally reflect unadjusted prices obtained from independent valuation service providers and indicative, non-binding quotes obtained from third-party broker-dealers recognized as market participants. Significant increases or decreases in the fair value amounts received from these pricing sources may result in the Company’s reporting significantly higher or lower fair value measurements for these Leve

Retirement Benefits [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS AXA Financial and AXA Equitable Life Plans AXA Equitable Life sponsors the AXA Equitable 401(k) Plan, a qualified defined contribution plan for eligible employees and financial professionals. The plan provides for both a company contribution and a discretionary profit-sharing contribution. Expenses associated with this 401(k) Plan were $9 million and $7 million in the three months ended March 31, 2018 and 2017 , respectively. AXA Financial sponsors the MONY Life Retirement Income Security Plan for Employees and AXA Equitable Life sponsors the AXA Equitable Retirement Plan (the “AXA Equitable Life QP”), both of which are frozen qualified defined benefit plans covering eligible employees and financial professionals. These pension plans are non-contributory and their benefits are generally based on a cash balance formula and/or, for certain participants, years of service and average earnings over a specified period in the plans. AXA Financial and AXA Equitable Life also sponsor certain nonqualified defined benefit plans. On March 13, 2018, the Company signed a binding agreement with a third party insurer to purchase two single premium, non-participating group annuity contracts with the intent of settling certain retiree liabilities under the MONY Life Retirement Income Security Plan for Employees and the AXA Equitable QP. Payment of the preliminary contribution amounts for the group annuity contracts was funded from plan assets on March 20, 2018, securing the third party insurer’s irrevocable assumption of certain benefits obligations and commitment to issue the group annuity contracts. The annuity purchase transaction and consequent transfer of approximately $254 million of the plans’ obligations to retirees or 10% of the aggregate pension benefit obligations resulted in a partial settlement of the plans. Following remeasurement of the plans’ assets and obligations on March 20, 2018, as required in the event of an accounting settlement, the Company recognized a pre-tax settlement loss of approximately $100 million , largely attributable to recognition of a pro-rata portion of the plans’ unamortized net actuarial losses accumulated in other comprehensive income. AB AB maintains the Profit Sharing Plan for Employees of AB, a tax-qualified retirement plan for U.S. employees. Employer contributions under this plan are discretionary and generally are limited to the amount deductible for Federal income tax purposes. AB also maintains a qualified, non-contributory, defined benefit retirement plan covering current and former employees who were employed by AB in the United States prior to October 2, 2000 (the “AB Plan”). Benefits under the AB Plan are based on years of credited service and average final base salary. Service and compensation after December 31, 2008 are not taken into account in determining participants’ retirement benefits. In the three months ended March 31, 2018 , a $5 million cash contribution was made by AB to the AB Plan. Based on the funded status of the AB plan at March 31, 2018 , no minimum contribution is required to be made in 2018 under ERISA, as amended by the Pension Act, but management is currently evaluating if it will make contributions for the remainder of 2018 . Funding Policy The Company’s funding policy for its qualified pension plans is to satisfy its funding obligations each year in an amount not less than the minimum required by the ERISA, as amended by the Pension Act, and not greater than the maximum it can deduct for Federal income tax purposes. Components of certain benefit costs for the Company were as follows: Three Months Ended March 31, 2018 2017 (in millions) Net Periodic Pension Expense: (Qualified and Non-qualified Plans) Service cost $ 2 $ 3 Interest cost 25 26 Expected return on assets (45 ) (43 ) Net amortization 29 32 Partial settlement 100 — Total $ 111 $ 18 Net Postretirement Benefits Costs: Service cost $ — $ — Interest cost 4 4 Net amortization 2 2 Total $ 6 $ 6 Net Postemployment Benefits Costs: Service cost $ 1 $ 1 Interest cost — — Net amortization — — Total $ 1 $ 1

There were no open-market purchases during the three months ended March 31, 2018 . The three months ended March 31, 2017 amount reflects open-market purchases of 1.2 million AB Holding Units for $28 million , with the remainder relating to purchases of AB Holding Units from employees to allow them to fulfill statutory tax withholding requirements at the time of distribution of long-term incentive compensation awards. During the three months ended March 31, 2018 and 2017 , AB granted to employees and eligible Directors 1.1 million and 1.1 million restricted Holding awards, respectively. In the three months ended March 31, 2018 and 2017 , AB used AB Holding Units repurchased during the period and newly issued AB Holding Units to fund the restricted AB Holding Unit awards. During the three months ended March 31, 2018 and 2017 , AB Holding issued 0.2 million and 0.3 million , respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of $4 million and $5 million , respectively, received from employees as payment in cash for the exercise price to purchase the equivalent number of newly-issued AB Units.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company participates in certain cost sharing and service agreements with AXA and other non-consolidated affiliates, including technology, professional development and investment management agreements. The costs related to the cost sharing and service agreements are allocated based on methods that management believes are reasonable, including a review of the nature of such costs and the activities performed to support each company. There have been no material changes in these service agreements from those disclosed in the 2017 annual financial statements. In October 2012, AXA Financial issued a note denominated in Euros in the amount of €300 million or $391 million to AXA Belgium S.A. (“AXA Belgium”). This note had an interest rate of Europe Interbank Offered Rate (“EURIBOR”) plus 1.15% and a maturity date of October 23, 2017. Concurrently, AXA Financial entered into a swap with AXA covering the exchange rate on both the interest and principal payments related to this note. The interest rate on the swap was 6-month LIBOR plus 1.475% . In October 2017, the note was extended to March 30, 2018. The extended note has a floating interest rate of 1-month EURIBOR plus 0.06% with a minimum rate of 0% . Concurrently, AXA Financial entered into a swap with AXA covering the exchange rate on both the interest and principal payments related to the extended note until March 30, 2018. Both the loan and the swap were repaid on March 29, 2018. In 2017, Holdings repaid a $56 million 1.39% loan from AXA America Corporate Solutions, Inc. (“AXA CS”) originally made in 2015. In 2017, Holdings received a $100 million and $10 million loan from AXA CS. The loans had interest rates of 1.86% and 1.76% , respectively, and were repaid on their maturity date of February 5, 2018. Holdings formerly held 78.99% of the shares of AXA CS, which holds certain AXA U.S. P&C business. AXA CS and its subsidiaries have been excluded from the historical Consolidated Financial Statements since they were operated independently from the other Holdings subsidiaries. In March 2018, the legal transfer of the AXA CS shares to AXA was executed for $630 million , and is presented as an increase to Total equity attributable to Holdings. To anticipate this transfer, in the fourth quarter of 2017, AXA made a short-term loan of $622 million , 3-month LIBOR plus 0.439% margin to Holdings (the “ $622 Million Loan”). Holdings’ repayment obligation to AXA in respect of this loan was set off against AXA’s payment obligation to Holdings with respect to the transfer of AXA CS shares, and AXA paid Holdings the $8 million balance in cash. In September 2007, AXA received a $700 million 5.40% Senior Unsecured Note from AXA Equitable. The note pays interest semi-annually and was scheduled to mature on September 30, 2012. In March 2011, the maturity date of the note was extended to December 30, 2020 and the interest rate was increased to 5.70% . In January 2018, AXA pre-paid $50 million of the $700 million note. In December 2008, AXA received a $500 million term loan from AXA Financial. In December 2014, AXA repaid $300 million on this term loan to AXA Financial plus accrued interest. This term loan has an interest rate of 5.40% payable semi-annually with a maturity date of December 15, 2020. In January 2018, AXA pre-paid $150 million of the $500 million term loan. In December 2013, Colisée Re issued a $145 million 4.75% Senior Unsecured Note to Holdings. The loan was scheduled to mature on December 19, 2028. This loan was repaid on March 26, 2018. In March 2018, AXA Equitable Life sold its interest in two consolidated real estate joint ventures to AXA France for a total purchase price of approximately $143 million , which resulted in a pre-tax loss of $0.2 million and the reduction of $203 million of long-term debt on the Company’s balance sheet for the first quarter of 2018. In March 2018, AXA contributed the 0.5% noncontrolling interest in AXA Financial to Holdings, reflected as a $66 million capital contribution, resulting in AXA Financial being 100% owned by Holdings.

COMMITMENT AND CONTINGENT LIABI

COMMITMENT AND CONTINGENT LIABILITIES	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENT AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES Litigation Litigation, regulatory and other loss contingencies arise in the ordinary course of the Company’s activities as a diversified financial services firm. The Company is a defendant in a number of litigation matters arising from the conduct of its business. In some of these matters, claimants seek to recover very large or indeterminate amounts, including compensatory, punitive, treble and exemplary damages. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages and other relief. Claimants are not always required to specify the monetary damages they seek or they may be required only to state an amount sufficient to meet a court’s jurisdictional requirements. Moreover, some jurisdictions allow claimants to allege monetary damages that far exceed any reasonably possible verdict. The variability in pleading requirements and past experience demonstrates that the monetary and other relief that may be requested in a lawsuit or claim often bears little relevance to the merits or potential value of a claim. Litigation against the Company includes a variety of claims including, among other things, insurers’ sales practices, alleged agent misconduct, alleged failure to properly supervise agents, contract administration, product design, features and accompanying disclosure, cost of insurance increases, the use of captive reinsurers, payments of death benefits and the reporting and escheatment of unclaimed property, alleged breach of fiduciary duties, alleged mismanagement of client funds and other matters. As with other financial services companies, the Company periodically receives informal and formal requests for information from various state and federal governmental agencies and self-regulatory organizations in connection with inquiries and investigations of the products and practices of the Company or the financial services industry. It is the practice of the Company to cooperate fully in these matters. The outcome of a litigation or regulatory matter is difficult to predict and the amount or range of potential losses associated with these or other loss contingencies requires significant management judgment. It is not possible to predict the ultimate outcome or to provide reasonably possible losses or ranges of losses for all pending regulatory matters, litigation and other loss contingencies. While it is possible that an adverse outcome in certain cases could have a material adverse effect upon the Company’s financial position, based on information currently known, management believes that neither the outcome of pending litigation and regulatory matters, nor potential liabilities associated with other loss contingencies, are likely to have such an effect. However, given the large and indeterminate amounts sought in certain litigation and the inherent unpredictability of all such matters, it is possible that an adverse outcome in certain of the Company’s litigation or regulatory matters, or liabilities arising from other loss contingencies, could, from time to time, have a material adverse effect upon the Company’s results of operations or cash flows in a particular quarterly or annual period. For some matters, the Company is able to estimate a possible range of loss. For such matters in which a loss is probable, an accrual has been made. For matters where the Company, however, believes a loss is reasonably possible, but not probable, no accrual is required. For matters for which an accrual has been made, but there remains a reasonably possible range of loss in excess of the amounts accrued or for matters where no accrual is required, the Company develops an estimate of the unaccrued amounts of the reasonably possible range of losses. As of March 31, 2018 , the Company estimates the aggregate range of reasonably possible losses, in excess of any amounts accrued for these matters as of such date, to be up to approximately $90 million . For other matters, the Company is currently not able to estimate the reasonably possible loss or range of loss. The Company is often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from plaintiffs and other parties, investigation of factual allegations, rulings by a court on motions or appeals, analysis by experts and the progress of settlement discussions. On a quarterly and annual basis, the Company reviews relevant information with respect to litigation and regulatory contingencies and updates the Company’s accruals, disclosures and reasonably possible losses or ranges of loss based on such reviews. In July 2011, a derivative action was filed in the United States District Court for the District of New Jersey entitled Mary Ann Sivolella v. AXA Equitable Life Insurance Company and AXA Equitable Funds Management Group, LLC (“Sivolella Litigation”) and a substantially similar action was filed in January 2013 entitled Sanford et al. v. AXA Equitable FMG (“Sanford Litigation”). These lawsuits were filed on behalf of a total of twelve mutual funds and, among other things, seek recovery under (i) Section 36(b) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), for alleged excessive fees paid to AXA Equitable Life and AXA Equitable FMG for investment management services and administrative services and (ii) a variety of other theories including unjust enrichment. The Sivolella Litigation and the Sanford Litigation were consolidated and a 25 -day trial commenced in January 2016 and concluded in February 2016. In August 2016, the District Court issued its decision in favor of AXA Equitable Life and AXA Equitable FMG, finding that the plaintiffs had failed to meet their burden to demonstrate that AXA Equitable Life and AXA Equitable FMG breached their fiduciary duty in violation of Section 36(b) of the Investment Company Act or show any actual damages. In September 2016, the plaintiffs filed a motion to amend the District Court’s trial opinion and to amend or make new findings of fact and/or conclusions of law. In December 2016, the District Court issued an order denying the motion to amend and plaintiffs filed a notice to appeal the District Court’s decision to the U.S. Court of Appeals for the Third Circuit. We are vigorously defending this matter. In April 2014, a lawsuit was filed in the United States District Court for the Southern District of New York, now entitled Ross v. AXA Equitable Life Insurance Company. The lawsuit is a putative class action on behalf of all persons and entities that, between 2011 and March 11, 2014, directly or indirectly, purchased, renewed or paid premiums on life insurance policies issued by AXA Equitable Life (the “Policies”). The complaint alleges that AXA Equitable Life did not disclose in its New York statutory annual statements or elsewhere that the collateral for certain reinsurance transactions with affiliated reinsurance companies was supported by parental guarantees, an omission that allegedly caused AXA Equitable Life to misrepresent its “financial condition” and “legal reserve system.” The lawsuit seeks recovery under Section 4226 of the New York Insurance Law of all premiums paid by the class for the Policies during the relevant period. In July 2015, the Court granted AXA Equitable Life’s motion to dismiss for lack of subject matter jurisdiction. In April 2015, a second action in the United States District Court for the Southern District of New York was filed on behalf of a putative class of variable annuity holders with “Guaranteed Benefits Insurance Riders,” entitled Calvin W. Yarbrough, on behalf of himself and all others similarly situated v. AXA Equitable Life Insurance Company. The new action covers the same class period, makes substantially the same allegations, and seeks the same relief as the Ross action. In October 2015, the Court, on its own, dismissed the Yarbrough litigation on similar grounds as the Ross litigation. In December 2015, the Second Circuit denied the plaintiffs motion to consolidate their appeals but ordered that the appeals be heard together before a single panel of judges. In February 2017, the Second Circuit affirmed the decisions of the district court in favor of AXA Equitable Life, and that decision is now final because the plaintiffs failed to file a further appeal. In November 2014, a lawsuit was filed in the Superior Court of New Jersey, Camden County entitled Arlene Shuster, on behalf of herself and all others similarly situated v. AXA Equitable Life Insurance Company. This lawsuit is a putative class action on behalf of all AXA Equitable Life variable life insurance policyholders who allocated funds from their policy accounts to investments in AXA Equitable Life’s Separate Accounts, which were subsequently subjected to the volatility management strategy and who suffered injury as a result thereof. The action asserts that AXA Equitable Life breached its variable life insurance contracts by implementing the volatility management strategy. In February 2016, the Court dismissed the complaint. In March 2016, the plaintiff filed a notice of appeal. In April 2018, the Superior Court of New Jersey Appellate Division affirmed the trial court’s decision. In August 2015, another lawsuit was filed in Connecticut Superior Court, Judicial Division of New Haven entitled Richard T. O’Donnell, on behalf of himself and all others similarly situated v. AXA Equitable Life Insurance Company. This lawsuit is a putative class action on behalf of all persons who purchased variable annuities from AXA Equitable Life, which were subsequently subjected to the volatility management strategy and who suffered injury as a result thereof. Plaintiff asserts a claim for breach of contract alleging that AXA Equitable Life implemented the volatility management strategy in violation of applicable law. In November 2015, the Connecticut Federal District Court transferred this action to the United States District Court for the Southern District of New York. In March 2017, the Southern District of New York granted AXA Equitable Life’s motion to dismiss the complaint. In April 2017, the plaintiff filed a notice of appeal. In April 2018, the United States Court of Appeals for the Second Circuit reversed the trial court’s decision with instructions to remand the case to Connecticut state court. We are vigorously defending these matters. In February 2016, a lawsuit was filed in the United States District Court for the Southern District of New York entitled Brach Family Foundation, Inc. v. AXA Equitable Life Insurance Company. This lawsuit is a putative class action brought on behalf of all owners of universal life UL policies subject to AXA Equitable Life’s COI increase. In early 2016, AXA Equitable Life raised COI rates for certain UL policies issued between 2004 and 2007, which had both issue ages 70 and above and a current face value amount of $1 million and above. In March 2018, plaintiff amended its complaint to add two new plaintiffs, including the individual Malcolm Currie. The current complaint alleges the following claims: breach of contract; misrepresentations by AXA in violation of Section 4226 of the New York Insurance Law; violations of New York General Business Law Section 349; violations of the California Unfair Competition Law, and the California Elder Abuse Statute. Plaintiffs seek (a) compensatory damages, costs, and, pre- and post-judgment interest, (b) with respect to their claim concerning Section 4226, a penalty in the amount of premiums paid by the plaintiffs and the putative class, and (c) injunctive relief and attorneys’ fees in connection with their statutory claims. Seven individual actions challenging the COI increase are also pending against AXA Equitable Life in federal or state courts. They contain similar allegations as those in Brach as well as additional allegations for violations of various states’ consumer protection statutes and common law fraud. Pursuant to an October 2017 order, the putative class action and the four individual federal actions are consolidated for the purposes of coordinating pre-trial activities. We are in various stages of motion practice, and are vigorously defending each of these matters. Restructuring The restructuring costs and liabilities associated with the Company’s initiatives were as follows: Three Months Ended March 31, Twelve Months Ended December 31, 2018 2017 (in millions) Severance Balance, beginning of year $ 23 $ 22 Additions 7 17 Cash payments (3 ) (14 ) Other reductions — (2 ) Balance, end of Year $ 27 $ 23 Three Months Ended March 31, Twelve Months Ended December 31, 2018 2017 (in millions) Leases Balance, beginning of year $ 165 $ 170 Expense incurred — 29 Deferred rent 2 10 Payments made (11 ) (48 ) Interest accretion 1 4 Balance, end of year $ 157 $ 165 Obligation under funding agreements As a member of the FHLBNY, AXA Equitable Life has access to collateralized borrowings. It also may issue funding agreements to the FHLBNY. Both the collateralized borrowings and funding agreements would require AXA Equitable Life to pledge qualified mortgage-backed assets and/or government securities as collateral. AXA Equitable Life issues short-term funding agreements to the FHLBNY and uses the funds for asset liability and cash management purposes. AXA Equitable Life issues long-term funding agreements to the FHLBNY and uses the funds for spread lending purposes. For other instruments used for asset liability management purposes see “Derivative and offsetting assets and liabilities” included in Note 3 .

Credit Facilities and Notes All existing credit facilities at December 31, 2017 with AXA or guaranteed by AXA have been terminated prior to the IPO settlement. In February 2018, Holdings entered into the following credit facilities: (i) a $3.9 billion two -year senior unsecured delayed draw term loan agreement; (ii) a $500 million three -year senior unsecured delayed draw term loan agreement; and (iii) a $2.5 billion five -year senior unsecured revolving credit facility with a syndicate of banks. In addition to the credit facilities, Holdings entered into letter of credit facilities with an aggregate principal amount of approximately $1.9 billion , primarily to be used to support our life insurance business reinsured to EQ AZ Life Re following the unwind of the reinsurance provided to AXA Equitable Life by AXA RE Arizona for certain variable annuities with GMxB features (the “GMxB Unwind”). As of March 31, 2018, there were no outstanding balances on these credit facilities. Other Commitments The Company had $812 million (including $262 million with affiliates) and $712 million of commitments under equity financing arrangements to certain limited partnership and existing mortgage loan agreements, respectively, at March 31, 2018.

Segment Reporting [Abstract]
BUSINESS SEGMENT INFORMATION	BUSINESS SEGMENT INFORMATION The Company has four reportable segments: Individual Retirement, Group Retirement, Investment Management and Research and Protection Solutions. The Company changed its segment presentation in the fourth quarter 2017. The segment disclosures are based on the intention to provide the users of the financial statements with a view of the business from the Company’s perspective. As a result, the Company determined that it is more useful for a user of the financial statements to assess the historical performance on the basis which management currently evaluates the business. The reportable segments are based on the nature of the business activities, as they exist as of the initial filing date. These segments reflect the manner by which the Company’s chief operating decision maker views and manages the business. A brief description of these segments follows: • The Individual Retirement segment offers a diverse suite of variable annuity products which are primarily sold to affluent and high net worth individuals saving for retirement or seeking retirement income. • The Group Retirement segment offers tax-deferred investment and retirement plans to be sponsored by educational entities, municipalities and not-for-profit entities as well as small and medium-sized businesses. • The Investment Management and Research segment provides diversified investment management, research and related solutions globally to a broad range of clients through three main client channels- Institutional, Retail and Private Wealth Management-and distributes its institutional research products and solutions through Bernstein Research Services. • The Protection Solutions segment includes our life insurance and group employee benefits businesses. Our life insurance business offers a variety of variable universal life, universal life and term life products to help affluent and high net worth individuals, as well as small and medium-sized business owners, with their wealth protection, wealth transfer and corporate needs. Our group employee benefits business offers a suite of dental, vision, life, and short- and long-term disability and other insurance products to small and medium-size businesses across the United States. Measurement Operating earnings (loss) is the financial measure which primarily focuses on the Company’s segments’ results of operations as well as the underlying profitability of the Company’s core business. By excluding items that can be distortive and unpredictable such as investment gains (losses) and investment income (loss) from derivative instruments, the Company believes operating earnings (loss) by segment enhances the understanding of the Company’s underlying drivers of profitability and trends in the Company’s segments. In the first quarter of 2018, the Company revised its Operating earnings definition as it relates to the treatment of certain elements of the profitability of its variable annuity products with indexed-linked features to align to the treatment of its variable annuity products with GMxB features. In addition, adjustments for variable annuity products with index-linked features previously included within Other adjustments in the calculation of Non-GAAP Operating Earnings are now included with the adjustments for variable annuity products with GMxB features in the broader adjustment category, Variable annuity product features. In order to improve the consistency and comparability of the financial statements, management revised the Notes to the Consolidated Financial Statements for the six months ended June 30, 2017, nine months ended September 30, 2017 and the year ended December 31, 2017 to include the revisions discussed herein. See Note 17 to the Notes to Consolidated Financial Statements for details of the revisions. Operating earnings is calculated by adjusting each segment’s Net income (loss) attributable to Holdings for the following items: • Items related to Variable annuity product features which include certain changes in the fair value of the derivatives and other securities we use to hedge these features and changes in the fair value of the embedded derivatives of our GMxB riders reflected within Variable annuity products’ net derivative results; • Investment (gains) losses, which includes other-than-temporary impairments of securities, sales or disposals of securities/investments, realized capital gains/losses and valuation allowances; • Goodwill impairment, which includes a write-down of goodwill in first quarter of 2017. • Net actuarial (gains) losses, which includes actuarial gains and losses as a result of differences between actual and expected experience on pension plan assets or projected benefit obligation during a given period related to pension, other postretirement benefit obligations and one time settlement of gains and losses; • Other adjustments, which includes restructuring costs related to severance, lease write-offs related to non-recurring restructuring activities and separation costs; and • Income tax expense (benefit) related to the above items and non-recurring tax items, which includes the effect of uncertain tax positions for a given audit period, and permanent differences due to goodwill impairment and the Tax Reform Act. Revenues derived from any customer did not exceed 10% of revenues for the three months ended March 31, 2018 and 2017 . The table below presents operating earnings (loss) by segment and Corporate and Other and a reconciliation to Net income (loss) attributable to Holdings for the three months ended March 31, 2018 and 2017 , respectively: Three Months Ended March 31, 2018 2017 (in millions) Net income (loss) attributable to Holdings $ 168 $ (290 ) Adjustments related to: Variable annuity product features 212 291 Investment (gains) losses (102 ) 24 Goodwill impairment — 369 Net actuarial (gains) losses related to pension and other postretirement benefit obligations 131 34 Other adjustments 90 (21 ) Income tax expense (benefit) related to above adjustments (63 ) (235 ) Non-recurring tax items 28 132 Non-GAAP Operating Earnings $ 464 $ 304 Operating earnings (loss) by segment: Individual Retirement $ 360 $ 202 Group Retirement 76 59 Investment Management and Research 81 32 Protection Solutions 23 39 Corporate and Other (1) (76 ) (28 ) (1) Includes interest expense of $ 44 million and $ 31 million , for the three months ended March 31, 2018 and 2017 , respectively. Segment revenues are a measure of the Company’s revenue by segment as adjusted to exclude certain items. The following table reconciles segment revenues to Total revenues by excluding the following items: • Items related to variable annuity product features, which include certain changes in the fair value of the derivatives and other securities we use to hedge these features and changes in the fair value of the embedded derivatives reflected within the net derivative results of variable annuity product features; • Investment gains (losses), which include other-than-temporary impairments of securities, sales or disposals of securities/investments, realized capital gains/losses, and valuation allowances; and • Other adjustments, which includes the impact of adoption of revenue recognition standard ASC 606. The table below presents segment revenues for the three months ended March 31, 2018 and 2017 : Three Months Ended March 31, 2018 2017 (in millions) Segment revenues: Individual Retirement (1) $ 729 $ 1,019 Group Retirement (1) 238 227 Investment Management and Research (2) 909 743 Protection Solutions (1) 809 789 Corporate and Other (1) 288 340 Adjustments related to: Variable annuity product features (197 ) (287 ) Investment gains (losses) 102 (24 ) Other adjustments to segment revenues (43 ) 23 Total revenues $ 2,835 $ 2,830 (1) Includes investment expenses charged by AB of approximately $ 18 million and $ 17 million for the three months ended March 31, 2018 and 2017 , respectively, for services provided to the Company.

Accounting Changes and Error Corrections [Abstract]
REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS	REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS During the first quarter of 2018, management identified an error in its previously issued financial statements related to a misclassification between interest credited and net derivative gains/losses. The impact of this error to the consolidated financial statements for the six months ended June 30, 2017, nine months ended September 30, 2017 and the years ended December 31, 2017 and 2016 was not considered to be material. In order to improve the consistency and comparability of the financial statements, management revised the consolidated statements of income (loss) and statements of cash flows to include the revisions discussed herein. The following tables present line items for prior period financial statements that have been affected by the revisions. For these items, the tables detail the amounts as previously reported, the impact upon those line items due to the revisions, and the amounts as currently revised within the financial statements.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS In April 2018, Holdings entered into letter agreements with the lenders under each of its credit facilities and letter of credit facilities, and AXA Equitable Life entered into waiver letter agreements with certain of its derivative counterparties, waiving defaults caused by the restatement of certain financial statements. Holdings and AXA Equitable Life each restated their annual financial statements for the year ended December 31, 2016 and Holdings restated its interim financial statements for the nine months ended September 30, 2017 and the six months ended June 30, 2017. All required waivers were received and we do not consider this to have a material impact on our business, results of operations or financial condition. In April 2018, Colisee Re S.A.’s promise to the Delaware Department of Insurance to maintain the minimum RBC level for AXA Corporate Solutions Life Reinsurance Company at the company action level was terminated and replaced with a similar guarantee from Holdings. As a result of the completion of the GMxB Unwind on April 12, 2018, we were released from regulatory letter of credit requirements, and accordingly no longer benefit from the $1.5 billion revolving credit facility with AXA. On April 20, 2018, Holdings: • issued $800 million aggregate principal amount of 3.900% Senior Notes due 2023, $1.5 billion aggregate principal amount of 4.350% Senior Notes due 2028 and $1.5 billion aggregate principal amount of 5.000% Senior Notes due 2048 (together, the “Notes”); • delivered a termination notice, effective April 23, 2018, for its $3.9 billion two -year senior unsecured delayed draw term loan agreement; and • settled certain loans issued to or received from AXA and its affiliates resulting in a net payment to AXA and its affiliates of $2,530 million in principal and $11 million of accrued interest. On April 20, 2018, AXA pre-paid the remaining $650 million of a $700 million note and $50 million of a $500 million term loan and related accrued interest from the Company. On April 23, 2018, Holdings used a portion of the net proceeds from the sale of the Notes, together with available cash, to (i) purchase 100% of the shares of AXA IM Holdings US and (ii) purchase the AB Units held by Coliseum Re. The Company’s $185 million loan to AXA IM Holding US was settled as part of the purchase of AXA IM Holding US, which wholly owns AB units. The remaining net proceeds, together with the $300 million of borrowings drawn on May 4th, 2018 under our three -year term loan agreement, was used to fully repay the outstanding commercial paper program of AXA Financial currently guaranteed by AXA. By the time of the IPO, all the credit facilities Holdings and its subsidiaries previously had with AXA or guaranteed by AXA were terminated. On April 24, 2018, a 459.4752645 -for-1 stock split of the common stock of Holdings was effected. All applicable share data, per share amounts and related information in the consolidated financial statements and notes thereto have been adjusted retroactively to give effect to the stock split. On April 25, 2018, Holdings adopted the AXA Equitable Holdings, Inc. Short-Term Incentive Compensation Plan (the “STIC Plan”). Although the STIC Plan is not a share-based compensation plan, awards payable under the STIC Plan may be paid in cash or in awards granted under the AXA Equitable Holdings, Inc. 2018 Omnibus Incentive Plan (the “Omnibus Plan”), a share-based compensation plan. The Omnibus Plan was adopted by Holdings on May 8, 2018. On May 2, 2018, AB announced that it will establish its corporate headquarters in, and relocate approximately 1,050 jobs currently located in the New York metro area to, Nashville, TN. AB’s Nashville headquarters will house Finance, IT, Operations, Legal, Compliance, Internal Audit, Human Capital, and Sales and Marketing. AB will begin relocating jobs during 2018 and expects this transition to take several years. AB will continue to maintain a principal location in New York City, which will house its Portfolio Management, Sell-Side Research and Trading, and New York-based Private Wealth Management businesses. On May 4, 2018, Holdings borrowed $300 million under the $500 million three -year senior unsecured delayed draw term loan agreement. On May 9, 2018, Holdings amended and restated its Certificate of Incorporation under which the Board of Directors have the authority, without further action by stockholders, to issue up to 200,000,000 shares of preferred stock, par value $1.00 per share, in one or more series. On May 14, 2018, Holdings completed an initial public offering in which AXA sold 157,837,500 shares of Holdings’ common stock to the public. Following the initial public offering, AXA owned 423,750,000 shares of Holdings’ common stock. As of June 12th, there are no longer any amounts outstanding under AXA Financial’s commercial paper program and AXA will no longer provide any related guarantees.

SIGNIFICANT ACCOUNTING POLICI28

SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Intercompany balances and transactions have been eliminated. In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.
Adoption of New Accounting Pronouncements and Future Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance that revises the recognition criteria for revenue arising from contracts with customers to provide goods or services, except when those revenue streams are from insurance and investment contracts, leases, rights and obligations that are in the scope of certain financial instruments (i.e., derivative contracts) and guarantees other than product or service warranties, for which existing revenue recognition requirements are not superseded by this guidance. On January 1, 2018, the Company adopted the new revenue recognition guidance on a modified retrospective basis and is providing in its first quarter 2018 reporting the additional disclosures required by the new standard. Adoption of this new guidance did not change the amounts or timing of the Company’s revenue recognition for base investment management and advisory fees, distribution revenues, shareholder servicing revenues, and broker-dealer revenues. However, some performance-based fees and carried-interest distributions that prior to adoption were recognized when no risk of reversal remained, in certain instances under the new standard may be recognized earlier if it is probable that significant reversal will not occur. As a result, on January 1, 2018, the Company recognized a cumulative effect adjustment, net of tax, to increase opening equity attributable to Holdings and the noncontrolling interest by approximately $13 million and $19 million , respectively, reflecting the impact of carried-interest distributions previously received by AB of approximately $78 million , net of revenue sharing payments to investment team members of approximately $43 million , for which it is probable that significant reversal will not occur and for which incremental tax is provided at Holdings. In January 2016, the FASB issued new guidance related to the recognition and measurement of financial assets and financial liabilities. The new guidance primarily affects the accounting for equity investments, financial liabilities under the fair value option, and presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale (“AFS”) debt securities. The new guidance requires equity investments in unconsolidated entities, except those accounted for under the equity method, to be measured at fair value through earnings, thereby eliminating the AFS classification for equity securities with readily determinable fair values for which changes in fair value currently are reported in Accumulated Other Comprehensive Income (Loss) (“AOCI”). On January 1, 2018, the Company adopted the new recognition requirements on a modified retrospective basis for changes in the fair value of AFS equity securities, resulting in no material reclassification adjustment from AOCI to opening retained earnings for the net unrealized gains, net of tax, related to approximately $46 million common stock securities and eliminated their designation as AFS equity securities. The new guidance does not apply to FHLB common stock and prohibits such investments from being classified as equity securities subject to the new guidance. Accordingly, the Company has classified its investment in the FHLB common stock as other invested assets at March 31, 2018. The Company’s investment assets held in the form of equity interests in unconsolidated entities, such as limited partnerships and limited liability companies, including hedge funds, private equity funds, and real estate-related funds, generally are accounted for under the equity method and were not impacted by this new guidance. The Company does not currently report any of its financial liabilities under the fair value option. In March 2017, the FASB issued new guidance on the presentation of net periodic pension and post-retirement benefit costs that requires retrospective disaggregation of the service cost component from the other components of net benefit costs on the income statement. The service cost component is required to be presented with other employee compensation costs in “income from operations,” and the remaining components are to be reported separately outside of income from operations. While this standard did not change how net periodic pension and post-retirement benefit costs are measured, it limits the amount eligible for capitalization on a prospective basis to the service cost component. On January 1, 2018, the Company adopted the change in the income statement presentation utilizing the practical expedient for determining the historical components of net benefit costs, resulting in no material impact to the consolidated financial statements. In addition, no changes to the Company’s capitalization policies with respect to benefit costs resulted from the adoption of the new guidance. In May 2017, the FASB issued guidance on share-based payments. The amendment provides clarity intended to reduce diversity in practice and the cost and complexity of accounting for changes to the terms or conditions of share-based payment awards. The new guidance is effective for interim and annual periods beginning after December 15, 2017 and requires prospective application to awards modified on or after the date of adoption. Adoption of this amendment on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued new guidance to simplify elements of cash flow classification. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The new guidance is effective for interim and annual periods beginning after December 15, 2017 and requires application of a retrospective transition method. Adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Future Adoption of New Accounting Pronouncements In February 2018, the FASB issued new guidance that will permit, but not require, entities to reclassify to retained earnings tax effects “stranded” in AOCI resulting from the change in federal tax rate enacted by the Tax Cuts and Jobs Act (the “Tax Reform Act”) on December 22, 2017. An entity that elects this option must reclassify these stranded tax effects for all items in AOCI, including, but not limited to, AFS securities and employee benefits. Tax effects stranded in AOCI for other reasons, such as prior changes in tax law, may not be reclassified. While the new guidance provides entities the option to reclassify these amounts, new disclosures are required regardless of whether entities elect to do so. The new guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. Election can be made either to apply the new guidance retrospectively to each period in which the effect of the Tax Reform Act is recognized or in the period of adoption. Management currently is evaluating the options provided for adopting this guidance and the potential impacts on the Company’s consolidated financial statements. In August 2017, the FASB issued new guidance on accounting for hedging activities, intended to more closely align the financial statement reporting of hedging relationships to the economic results of an entity’s risk management activities. In addition, the new guidance makes certain targeted modifications to simplify the application of current hedge accounting guidance. The new guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early application permitted. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). All transition requirements and elections should be applied to derivatives positions and hedging relationships existing on the date of adoption. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In March 2017, the FASB issued guidance that requires certain premiums on callable debt securities to be amortized to the earliest call date and is intended to better align interest income recognition with the manner in which market participants price these instruments. The new guidance is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted and is to be applied on a modified retrospective basis. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In June 2016, the FASB issued new guidance related to the accounting for credit losses on financial instruments. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for annual periods beginning after December 15, 2018. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements. In February 2016, the FASB issued revised guidance to lease accounting that will require lessees to recognize on the balance sheet a “right-of-use” asset and a lease liability for virtually all lease arrangements, including those embedded in other contracts. The new lease accounting model will continue to distinguish between capital and operating leases. The current straight-line pattern for the recognition of rent expense on an operating lease is expected to remain substantially unchanged by the new guidance but instead will be comprised of amortization of the right-of-use asset and interest cost on the related lease obligation, thereby resulting in an income statement presentation similar to a financing arrangement or capital lease. Lessor accounting will remain substantially unchanged from the current model but has been updated to align with certain changes made to the lessee model. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The transition provisions require application on a modified retrospective approach at the beginning of the earliest comparative period presented in the financial statements (that is, January 1, 2017). Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing lease contracts and arrangements. Management currently is evaluating the impact that adoption of this guidance will have on the Company’s consolidated financial statements.
Revenue Recognition	Revenue Recognition Investment Management and Service Fees and Related Expenses Reported as Investment management and service fees in the Company’s consolidated statements of income (loss) are investment advisory and service fees, distribution revenues, and institutional research services revenues principally emerging from the Investment Management and Research segment. Also included are investment management and administrative service fees earned by AXA Equitable Funds Management Group, LLC (“AXA Equitable FMG”) and reported in the Retirement and Protection segments as well as certain asset-based fees associated with insurance contracts. Investment management, advisory, and service fees AB provides asset management services by managing customer assets and seeking to deliver returns to investors. Similarly, AXA Equitable FMG provides investment management and administrative services, such as fund accounting and compliance services, to AXA Premier VIP Trust (“VIP Trust”), EQ Advisors Trust (“EQAT”) and 1290 Funds as well as two private investment trusts established in the Cayman Islands, AXA Allocation Funds Trust and AXA Offshore Multimanager Funds Trust (collectively, the “Other AXA Trusts”). The contracts supporting these revenue streams create a distinct, separately identifiable performance obligation for each day the assets are managed for the performance of a series of services that are substantially the same and have the same pattern of transfer to the customer. Accordingly, these investment management, advisory, and administrative service base fees are recorded over time as services are performed and entitle the Company to variable consideration. Base fees, generally calculated as a percentage of assets under management (“AUM”), are recognized as revenue at month-end when the transaction price no longer is variable and the value of the consideration is determined. These fees are not subject to claw back and there is minimal probability that a significant reversal of the revenue recorded will occur. Certain investment advisory contracts of AB, including those associated with hedge funds or other alternative investments, provide for a performance-based fee (including carried interest), in addition to a base advisory fee, calculated either as a percentage of absolute investment results or a percentage of investment results in excess of a stated benchmark over a specified period of time. These performance-based fees are forms of variable consideration and, therefore, are excluded from the transaction price until it becomes probable there will not be significant reversal of the cumulative revenue recognized. At each reporting date, the Company evaluates constraining factors surrounding the variable consideration to determine the extent to which, if any, revenues associated with the performance-based fee can be recognized. Constraining factors impacting the amount of variable consideration included in the transaction price include contractual claw-back provisions, the length of time of the uncertainty, the number and range of possible amounts, the probability of significant fluctuations in fund’s market value, and the level in which the fund’s value exceeds the contractual threshold required to earn such a fee and the materiality of the amount being evaluated. Prior to adoption of the new revenue recognition guidance on January 1, 2018, the Company recognized performance-based fees at the end of the applicable measurement period when no risk of reversal remained, and carried-interest distributions received as deferred revenues until no risk of reversal remained. Sub-advisory and sub-administrative expenses associated with these services are calculated and recorded as the related services are performed in Other operating costs and expense in the consolidated statements of income (loss) as the Company is acting in a principal capacity in these transactions and, as such, reflects these revenues and expenses on a gross basis. Research services Research services revenue principally consists of brokerage transaction charges received by Sanford C. Bernstein & Co. LLC (“SCB LLC”) and Sanford C. Bernstein Limited (“SCBL”) for providing equity research services to institutional clients. Brokerage commissions for trade execution services and related expenses are recorded on a trade-date basis when the performance obligations are satisfied. Generally, the transaction price is agreed upon at the point of each trade and based upon the number of shares traded or the value of the consideration traded. Research revenues are recognized when the transaction price is quantified, collectability is assured, and significant reversal of such revenue is not probable. Distribution services Revenues from distribution services include fees received as partial reimbursement of expenses incurred in connection with the sale of certain AB sponsored mutual funds and the 1290 Funds and for the distribution primarily of EQAT and VIP Trust shares to separate accounts in connection with the sale of variable life and annuity contracts. The amount and timing of revenues recognized from performance of these distribution services often is dependent upon the contractual arrangements with the customer and the specific product sold as further described below. Most open-end management investment companies, such as U.S. funds and the EQAT and VIP Trusts and the 1290 Funds, have adopted a plan under Rule 12b-1 of the Investment Company Act that allows for certain share classes to pay out of assets, distribution and service fees for the distribution and sale of its shares (“12b-1 Fees”). These open-end management investment companies have such agreements with the Company, and the Company has selling and distribution agreements pursuant to which it pays sales commissions to the financial intermediaries that distribute the shares. These agreements may be terminated by either party upon notice (generally 30 days) and do not obligate the financial intermediary to sell any specific amount of shares. The Company records 12b-1 fees monthly based upon a percentage of the net asset value (“NAV”) of the funds. At month-end, the variable consideration of the transaction price is no longer constrained as the NAV can be calculated and the value of consideration is determined. These services are separate and distinct from other asset management services as the customer can benefit from these services independently of other services. The Company accrues the corresponding 12b-1 fees paid to sub-distributors monthly as the expenses are incurred. The Company is acting in a principal capacity in these transactions; as such, these revenues and expenses are recorded on a gross basis in the consolidated statements of income (loss). AB sponsored mutual funds offer back-end load shares in limited instances and charge the investor a contingent deferred sales charge (“CDSC”) if the investment is redeemed within a certain period. The variable consideration for these contracts is contingent upon the timing of the redemption by the investor and the value of the sales proceeds. Due to these constraining factors, the Company excludes the CDSC fee from the transaction price until the investor redeems the investment. Upon redemption, the cash consideration received for these contractual arrangements is recorded as a reduction of unamortized deferred sales commissions. AB’s Luxembourg subsidiary, the management company for most of its non-U.S. funds, earns a management fee which is accrued daily and paid monthly, at an annual rate, based on the average daily net assets of the fund. With respect to certain share classes, the management fee also may contain a component paid to distributors and other financial intermediaries and service providers to cover shareholder servicing and other administrative expenses (also referred to as an “All-in-Fee”). Based on the conclusion that asset management is distinct from distribution, the Company allocates a portion of the investment and advisory fee to distribution revenues for the servicing component based on standalone selling prices. Other revenues Also reported as Investment management and service fees in the Company’s consolidated statements of income (loss) are other revenues from contracts with customers, primarily consisting of shareholder servicing fees, mutual fund reimbursements, and other brokerage income. Shareholder services, including transfer agency, administration, and record-keeping are provided by AB to company-sponsored mutual funds. The consideration for these services is based on a percentage of the NAV of the fund or a fixed-fee based on the number of shareholder accounts being serviced. The revenues are recorded at month-end when the constraining factors involved with determining NAV or the numbers of shareholders’ accounts are resolved. Other income Revenues from contracts with customers reported as Other income in the Company’s consolidated statements of income (loss) primarily consist of advisory account fees and brokerage commissions from the Company’s subsidiary broker-dealer operations and sales commissions from the Company’s general agent for the distribution of non-affiliate insurers’ life insurance and annuity products. These revenues are recognized at month-end when constraining factors, such as AUM and product mix, are resolved and the transaction pricing no longer is variable such that the value of consideration can be determined. Contract assets and liabilities The Company applies the practical expedient for contracts that have an original duration of one year or less. Accordingly, the Company accrues the incremental costs of obtaining a contract when incurred and does not consider the time value of money. At March 31, 2018, there are no material balances of contract assets and contract liabilities; as such, no further disclosures are necessary.
Accounting and Consolidation of VIEs	Accounting and Consolidation of VIEs A VIE must be consolidated by its primary beneficiary, which generally is defined as the party that has a controlling financial interest in the VIE. The Company is deemed to have a controlling financial interest in a VIE if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE or the right to receive income from the VIE that potentially could be significant to the VIE. For purposes of evaluating (ii) above, fees paid to the Company as a decision maker or service provider are excluded if the fees are compensation for services provided commensurate with the level of effort required to be performed and the arrangement includes only customary terms, conditions or amounts present in arrangements for similar services negotiated at arm’s length. If the Company has a variable interest in an entity that is determined not to be a VIE, the entity then is evaluated for consolidation under the voting interest entity (“VOE”) model. For limited partnerships and similar entities, the Company is deemed to have a controlling financial interest in a VOE, and would be required to consolidate the entity, if the Company owns a majority of the entity’s kick-out rights through voting limited partnership interests and other limited partners do not hold substantive participating rights (or other rights that would indicate that the Company does not control the entity). For entities other than limited partnerships, the Company is deemed to have a controlling financial interest in a VOE if it owns a majority voting interest in the entity. The analysis performed to identify variable interests held, determine whether entities are VIEs or VOEs, and evaluate whether the Company has a controlling financial interest in such entities requires the exercise of judgment and is updated on a continuous basis as circumstances change or new entities are developed. The primary beneficiary evaluation generally is performed qualitatively based on all facts and circumstances, including consideration of economic interests in the VIE held directly and indirectly through related parties and entities under common control, as well as quantitatively, as appropriate.
Revision of Prior Period Financial Statements	Revision of Prior Period Financial Statements During the first quarter of 2018, management identified an error in its previously issued financial statements related to a misclassification between interest credited and net derivative gains/losses. The impact of this error to the consolidated financial statements for the six months ended June 30, 2017, nine months ended September 30, 2017 and the years ended December 31, 2017 and 2016 was not considered to be material. In order to improve the consistency and comparability of the financial statements, management revised the consolidated statements of income (loss) and statements of cash flows to include the revisions discussed herein.
Fair Value Measurement	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance established a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value, and identifies three levels of inputs that may be used to measure fair value: Level 1 Unadjusted quoted prices for identical instruments in active markets. Level 1 fair values generally are supported by market transactions that occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar instruments, quoted prices in markets that are not active, and inputs to model-derived valuations that are directly observable or can be corroborated by observable market data. Level 3 Unobservable inputs supported by little or no market activity and often requiring significant management judgment or estimation, such as an entity’s own assumptions about the cash flows or other significant components of value that market participants would use in pricing the asset or liability. The Company uses unadjusted quoted market prices to measure the fair value of instruments that are actively traded in financial markets. In cases where quoted market prices are not available, fair values are measured using present value or other valuation techniques. The fair value determinations are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of the timing and amount of expected future cash flows and the credit standing of counterparties. Such adjustments do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument, nor do they consider the tax impact of the realization of unrealized gains or losses. In many cases, the fair value cannot be substantiated by direct comparison to independent markets, nor can the disclosed value be realized in immediate settlement of the instrument. Management is responsible for the determination of the value of investments carried at fair value and the supporting methodologies and assumptions. Under the terms of various service agreements, the Company often utilizes independent valuation service providers to gather, analyze, and interpret market information and derive fair values based upon relevant methodologies and assumptions for individual securities. These independent valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested. As further described below with respect to specific asset classes, these inputs include, but are not limited to, market prices for recent trades and transactions in comparable securities, benchmark yields, interest rate yield curves, credit spreads, quoted prices for similar securities, and other market-observable information, as applicable. Specific attributes of the security being valued also are considered, including its term, interest rate, credit rating, industry sector, and when applicable, collateral quality and other security- or issuer-specific information. When insufficient market observable information is available upon which to measure fair value, the Company either will request brokers knowledgeable about these securities to provide a non-binding quote or will employ internal valuation models. Fair values received from independent valuation service providers and brokers and those internally modeled or otherwise estimated are assessed for reasonableness.

Fair Value Disclosures [Abstract]
Assets and Liabilities Measured at Fair Value on Recurring Basis	Assets and liabilities measured at fair value on a recurring basis are summarized below. At March 31, 2018 and December 31, 2017 , no assets were required to be measured at fair value on a non-recurring basis. Fair value measurements are required on a non-recurring basis for certain assets, including goodwill and mortgage loans on real estate, only when an OTTI or other event occurs.
