Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BUSINESS AND BASIS OF PRESENTATION Prudential Financial, Inc. (“Prudential Financial”) and its subsidiaries (collectively, “Prudential” or the “Company” or “PFI”) provide a wide range of insurance, investment management, and other financial products and services to both individual and institutional customers throughout the United States and in many other countries. Principal products and services provided include life insurance, annuities, retirement-related services, mutual funds and investment management. The Company’s principal operations are comprised of four divisions: the U.S. Retirement Solutions and Investment Management division, the U.S. Individual Life and Group Insurance division, the International Insurance division and the Closed Block division. The Closed Block division is accounted for as a divested business that is reported separately from the divested businesses that are included in the Company’s Corporate and Other operations. The Company’s Corporate and Other operations include corporate items and initiatives that are not allocated to business segments and businesses that have been or will be divested, excluding the Closed Block division. 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. The Unaudited Interim Consolidated Financial Statements include the accounts of Prudential Financial, entities over which the Company exercises control, including majority-owned subsidiaries and variable interest entities (“VIEs”) in which the Company is considered the primary beneficiary. See Note 5 for more information on the Company’s consolidated variable interest entities. 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, 2016 . The Company’s Gibraltar Life Insurance Company, Ltd. (“Gibraltar Life”) consolidated operations use a November 30 fiscal year end for purposes of inclusion in the Company’s Consolidated Financial Statements. The Company’s unaudited interim consolidated balance sheet data as of March 31, 2017 , include the assets and liabilities of Gibraltar Life as of February 28, 2017. The Company’s unaudited interim consolidated income statement data include Gibraltar Life’s results of operations for the three months ended February 28, 2017 and February 29, 2016, respectively. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs (“DAC”) and related amortization; value of business acquired (“VOBA”) and its amortization; amortization of deferred sales inducements (“DSI”); measurement of goodwill and any related impairment; valuation of investments including derivatives and the recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; pension and other postretirement benefits; provision for income taxes and valuation of deferred tax assets; and accruals for contingent liabilities, including estimates for losses in connection with unresolved legal and regulatory matters. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Significant Accounting Policies

Significant Accounting Policies and Pronouncements	3 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies and Pronouncements	SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”) to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASU. ASU listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASU not listed below were assessed and determined to be either not applicable or not material. ASU adopted during the three months ended March 31, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-09 , Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payments Accounting This ASU simplifies and improves employee share-based payment accounting. The areas updated include income tax consequences, a policy election related to forfeitures, classification of awards as either equity or liability, and classification of operating and financing activity on the statement of cash flows. January 1, 2017 using various transition methods as prescribed by the ASU. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU issued but not yet adopted as of March 31, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2014-09 , Revenue from Contracts with Customers (Topic 606) The ASU is based on the core principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, and assets recognized from the costs to obtain or fulfill a contract with a customer. Revenue recognition for insurance contracts and financial instruments are explicitly scoped out of the standard. January 1, 2018 using one of two retrospective application methods (early adoption permitted beginning January 1, 2017). The Company plans to adopt the standard on January 1, 2018 using the modified retrospective application. Given that insurance contracts and financial instruments are explicitly scoped out of the standard, the Company’s assessment has focused on the Asset Management segment. Based on the assessment completed to date, the Company does not expect the adoption of the ASU to have a significant impact on the Asset Management segment’s results of operations. ASU 2016-01 , Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities The ASU revises an entity’s accounting related to the recognition and measurement of certain equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. The standard also amends certain disclosure requirements associated with the fair value of financial instruments. January 1, 2018 using the modified retrospective method. The amendments are to be applied prospectively as they relate to equity investments without readily determinable fair value. The Company’s equity investments, except for those accounted for using the equity method, will generally be carried on the Consolidated Statements of Financial Position at fair value with changes in fair value reported in current earnings. The Company is continuing to assess additional impacts of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-02 , Leases (Topic 842) This ASU ensures that assets and liabilities from all outstanding lease contracts are recognized on the balance sheet (with limited exception). The ASU substantially changes a Lessee’s accounting for leases and requires the recording on balance sheet of a “right-of-use” asset and liability to make lease payments for most leases. A Lessee will continue to recognize expense in its income statement in a manner similar to the requirements under the current lease accounting standard. For Lessors, the standard modifies classification criteria and accounting for sales-type and direct financing leases and requires a Lessor to derecognize the carrying value of the leased asset that is considered to have been transferred to a Lessee and record a lease receivable and residual asset (“receivable and residual” approach). The standard also eliminates the real estate specific provisions of the current standard (i.e., sale-leaseback). January 1, 2019 using the modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-13 , Financial Instruments-Credit Losses (Topic326): Measurement of Credit Losses on Financial Instruments This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current OTTI standard for available-for-sale debt securities to require the use of an allowance rather than a direct write down of the investment, and replaces existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method, however prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an OTTI was recognized prior to the date of adoption. Early adoption is permitted beginning January 1, 2019. The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-15 , Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force) This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows. January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-18 , Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued this ASU to address diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities in the Statement of Cash Flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. January 1, 2018 using the retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2017-01 , Business Combinations (Topic 805): Clarifying the Definition of a Business In January 2017, the FASB issued this ASU to provide a more robust framework to use in determining when a set of assets and activities (“set”) is a business and to address stakeholder feedback that the definition of a business in current GAAP is applied too broadly. The primary amendments in the ASU provide a screen to exclude transactions where substantially all the fair value of the transferred set is concentrated in a single asset, or group of similar assets, from being evaluated as a business. January 1, 2018 using the prospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. It is expected that our general account real estate acquisitions will no longer be accounted for as business combinations. ASU 2017-05 , Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets In February 2017, the FASB issued this ASU to clarify the scope and application of ASC 610-20 which provides guidance on accounting for the derecognition of a nonfinancial asset or an in substance nonfinancial asset that is not a business. The ASU defines an in substance nonfinancial asset and requires the application of certain recognition and measurement principles in the new revenue recognition standard when an entity derecognizes nonfinancial assets and in substance nonfinancial assets, and the counterparty is not a customer.

Gross unrealized losses are primarily attributable to general credit spread widening, increases in interest rates and foreign currency exchange rate movements. As of March 31, 2017 , the Company did not intend to sell these securities, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost basis.

As of December 31, 2016 , $9 million of the gross unrealized losses on equity securities represented declines in value of 20% or more, $8 million of which had been in a gross unrealized loss position for less than six months.

Variable Interest Entities

Variable Interest Entities	3 Months Ended

Variable Interest Entity, Measure of Activity [Abstract]
Variable Interest Entities	VARIABLE INTEREST ENTITIES In the normal course of its activities, the Company enters into relationships with various special-purpose entities and other entities that are deemed to be variable interest entities (“VIEs”). A VIE is an entity that either (1) has equity investors that lack certain essential characteristics of a controlling financial interest (including the ability to control activities of the entity, the obligation to absorb the entity’s expected losses and the right to receive the entity’s expected residual returns) or (2) lacks sufficient equity to finance its own activities without financial support provided by other entities, which in turn would be expected to absorb at least some of the expected losses of the VIE. The Company is the primary beneficiary if the Company has (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the entity and (2) the obligation to absorb losses of the entity that could be potentially significant to the VIE or the right to receive benefits from the entity that could be potentially significant. If the Company determines that it is the VIE’s primary beneficiary, it consolidates the VIE. Consolidated Variable Interest Entities The Company is the investment manager of certain asset-backed investment vehicles commonly referred to as collateralized loan obligations (“CLOs”) and certain other vehicles for which the Company earns fee income for investment management services, including real estate funds and certain investment structures in which the Company’s asset management business invests with other co-investors in investment funds referred to as feeder funds. The Company may sell or syndicate investments through these vehicles, principally as part of the strategic investing activity of the Company’s asset management businesses. Additionally, the Company may invest in securities issued by these vehicles. CLOs raise capital by issuing debt securities, and use the proceeds to purchase investments, typically interest-bearing financial instruments. The Company has analyzed these relationships and determined that for certain CLOs and other investment structures it is the primary beneficiary and consolidates these entities. This analysis includes a review of (1) the Company’s rights and responsibilities as investment manager and (2) variable interests (if any) held by the Company. The assets of these VIEs are restricted and must be used first to settle liabilities of the VIE. The Company is not required to provide, and has not provided, material financial or other support to any of these VIEs. Additionally, the Company is the primary beneficiary of certain VIEs in which the Company has invested, as part of its investment activities, but for which it is not the investment manager. These include structured investments issued by a VIE that manages yen-denominated investments coupled with cross-currency coupon swap agreements thereby creating synthetic dual currency investments. The Company’s involvement in the structuring of these investments combined with its economic interest indicates that the Company is the primary beneficiary. The Company has not provided material financial support or other support that was not contractually required to these VIEs. The table below reflects the carrying amount and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported. The liabilities primarily comprise obligations under debt instruments issued by the VIEs that are non-recourse to the Company. The creditors of these VIEs do not have recourse to the Company in excess of the assets contained within the VIEs. Consolidated VIEs for which the Company is the Investment Manager(1) Other Consolidated VIEs March 31, December 31, March 31, December 31, (in millions) Fixed maturities, available-for-sale $ 71 $ 65 $ 276 $ 269 Fixed maturities, held-to-maturity 84 81 820 783 Trading account assets supporting insurance liabilities 0 0 9 9 Other trading account assets 2,293 2,140 0 0 Commercial mortgage and other loans 509 503 0 0 Other long-term investments 1,154 1,083 95 114 Cash and cash equivalents 202 618 0 1 Accrued investment income 10 10 4 4 Other assets 485 424 0 1 Total assets of consolidated VIEs $ 4,808 $ 4,924 $ 1,204 $ 1,181 Notes issued by consolidated VIEs(2) $ 2,179 $ 2,150 $ 0 $ 0 Other liabilities 462 611 6 7 Total liabilities of consolidated VIEs $ 2,641 $ 2,761 $ 6 $ 7 __________ (1) Total assets of consolidated VIEs reflects $1,450 million and $1,386 million as of March 31, 2017 and December 31, 2016 , respectively, related to VIEs whose beneficial interests are wholly-owned by consolidated subsidiaries. (2) Recourse is limited to the assets of the respective VIE and does not extend to the general credit of Prudential Financial . As of March 31, 2017 and December 31, 2016 , the maturities of these obligations were greater than five years. Unconsolidated Variable Interest Entities The Company has determined that it is not the primary beneficiary of certain VIEs for which it is the investment manager. These VIEs consist primarily of CLOs and investment funds for which the Company has determined that it is not the primary beneficiary as it does not have both (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the entity and (2) the obligation to absorb losses of the entity that could be potentially significant to the VIE or the right to receive benefits from the entity that could be potentially significant. The Company’s maximum exposure to loss resulting from its relationship with unconsolidated VIEs for which it is the investment manager is limited to its investment in the VIEs, which was $622 million and $515 million at March 31, 2017 and December 31, 2016 , respectively. These investments are reflected in “Fixed maturities, available-for-sale,” “Other trading account assets, at fair value” and “Other long-term investments.” There are no liabilities associated with these unconsolidated VIEs on the Company’s Unaudited Interim Consolidated Statements of Financial Position. In the normal course of its activities, the Company will invest in joint ventures and limited partnerships. These ventures include hedge funds, private equity funds and real estate-related funds and may or may not be VIEs. The Company’s maximum exposure to loss on these investments, both VIEs and non-VIEs, is limited to the amount of its investment. The Company has determined that it is not required to consolidate these entities because either: (1) it does not control them or (2) it does not have the obligation to absorb losses of the entities that could be potentially significant to the entities or the right to receive benefits from the entities that could be potentially significant. The Company classifies these investments as “Other long-term investments” and its maximum exposure to loss associated with these entities was $8,138 million and $8,010 million as of March 31, 2017 and December 31, 2016 , respectively. In addition, in the normal course of its activities, the Company will invest in structured investments including VIEs for which it is not the investment manager. These structured investments typically invest in fixed income investments and are managed by third parties and include asset-backed securities, commercial mortgage-backed securities and residential mortgage-backed securities. The Company’s maximum exposure to loss on these structured investments, both VIEs and non-VIEs, is limited to the amount of its investment. See Note 4 for details regarding the carrying amounts and classification of these assets. The Company has not provided material financial or other support that was not contractually required to these structures. The Company has determined that it is not the primary beneficiary of these structures due to the fact that it does not control these entities.

Closed Block

Closed Block Disclosure [Abstract]
Closed Block	CLOSED BLOCK On December 18, 2001, the date of demutualization, Prudential Insurance established a closed block for certain in force participating insurance policies and annuity products, along with corresponding assets used for the payment of benefits and policyholders’ dividends on these products, (collectively the “Closed Block”), and ceased offering these participating products. The recorded assets and liabilities were allocated to the Closed Block at their historical carrying amounts. The Closed Block forms the principal component of the Closed Block division. The policies included in the Closed Block are specified individual life insurance policies and individual annuity contracts that were in force on the date of demutualization and for which Prudential Insurance is currently paying or expects to pay experience-based policy dividends. Assets have been allocated to the Closed Block in an amount that has been determined to produce cash flows which, together with revenues from policies included in the Closed Block, are expected to be sufficient to support obligations and liabilities relating to these policies, including provision for payment of benefits, certain expenses and taxes and to provide for continuation of the policyholder dividend scales in effect in 2000, assuming experience underlying such scales continues. To the extent that, over time, cash flows from the assets allocated to the Closed Block and claims and other experience related to the Closed Block are, in the aggregate, more or less favorable than what was assumed when the Closed Block was established, total dividends paid to Closed Block policyholders may be greater than or less than the total dividends that would have been paid to these policyholders if the policyholder dividend scales in effect in 2000 had been continued. Any cash flows in excess of amounts assumed will be available for distribution over time to Closed Block policyholders and will not be available to stockholders. If the Closed Block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from Prudential Insurance’s assets outside of the Closed Block. The Closed Block will continue in effect as long as any policy in the Closed Block remains in force unless, with the consent of the New Jersey insurance regulator, it is terminated earlier. The excess of Closed Block liabilities over Closed Block assets at the date of the demutualization (adjusted to eliminate the impact of related amounts in AOCI) represented the estimated maximum future earnings at that date from the Closed Block expected to result from operations attributed to the Closed Block after income taxes. In establishing the Closed Block, the Company developed an actuarial calculation of the timing of such maximum future earnings. If actual cumulative earnings of the Closed Block from inception through the end of any given period are greater than the expected cumulative earnings, only the expected earnings will be recognized in income. Any excess of actual cumulative earnings over expected cumulative earnings will represent undistributed accumulated earnings attributable to policyholders, which are recorded as a policyholder dividend obligation. The policyholder dividend obligation represents amounts to be paid to Closed Block policyholders as an additional policyholder dividend unless otherwise offset by future Closed Block performance that is less favorable than originally expected. If the actual cumulative earnings of the Closed Block from its inception through the end of any given period are less than the expected cumulative earnings of the Closed Block, the Company will recognize only the actual earnings in income. However, the Company may reduce policyholder dividend scales, which would be intended to increase future actual earnings until the actual cumulative earnings equaled the expected cumulative earnings. As of March 31, 2017 and December 31, 2016 , the Company recognized a policyholder dividend obligation of $1,746 million and $1,647 million , respectively, to Closed Block policyholders for the excess of actual cumulative earnings over the expected cumulative earnings. Additionally, accumulated net unrealized investment gains that have arisen subsequent to the establishment of the Closed Block have been reflected as a policyholder dividend obligation of $3,048 million and $3,011 million at March 31, 2017 and December 31, 2016 , respectively, to be paid to Closed Block policyholders unless offset by future experience, with a corresponding amount reported in AOCI. Closed Block liabilities and assets designated to the Closed Block, as well as maximum future earnings to be recognized from Closed Block liabilities and Closed Block assets, are as follows: March 31, December 31, (in millions) Closed Block liabilities Future policy benefits $ 49,091 $ 49,281 Policyholders’ dividends payable 962 932 Policyholders’ dividend obligation 4,794 4,658 Policyholders’ account balances 5,183 5,204 Other Closed Block liabilities 5,347 4,262 Total Closed Block liabilities 65,377 64,337 Closed Block assets Fixed maturities, available-for-sale, at fair value 39,886 38,696 Other trading account assets, at fair value 307 283 Equity securities, available-for-sale, at fair value 2,565 2,572 Commercial mortgage and other loans 9,491 9,437 Policy loans 4,607 4,660 Other long-term investments 3,083 3,020 Short-term investments 579 837 Total investments 60,518 59,505 Cash and cash equivalents 1,194 1,310 Accrued investment income 510 491 Other Closed Block assets 346 206 Total Closed Block assets 62,568 61,512 Excess of reported Closed Block liabilities over Closed Block assets 2,809 2,825 Portion of above representing accumulated other comprehensive income: Net unrealized investment gains (losses) 3,029 2,990 Allocated to policyholder dividend obligation (3,048 ) (3,011 ) Future earnings to be recognized from Closed Block assets and Closed Block liabilities $ 2,790 $ 2,804 Information regarding the policyholder dividend obligation is as follows: Three Months Ended (in millions) Balance, January 1 $ 4,658 Impact from earnings allocable to policyholder dividend obligation 99 Change in net unrealized investment gains (losses) allocated to policyholder dividend obligation 37 Balance, March 31 $ 4,794 Closed Block revenues and benefits and expenses are as follows for the periods indicated: Three Months Ended 2017 2016 (in millions) Revenues Premiums $ 605 $ 622 Net investment income 650 618 Realized investment gains (losses), net 273 (98 ) Other income (loss) 34 (7 ) Total Closed Block revenues 1,562 1,135 Benefits and Expenses Policyholders’ benefits 789 807 Interest credited to policyholders’ account balances 33 33 Dividends to policyholders 593 247 General and administrative expenses 97 103 Total Closed Block benefits and expenses 1,512 1,190 Closed Block revenues, net of Closed Block benefits and expenses, before income taxes 50 (55 ) Income tax expense (benefit) 37 (66 ) Closed Block revenues, net of Closed Block benefits and expenses and income taxes $ 13 $ 11

Stockholders' Equity Note [Abstract]
Equity	EQUITY The changes in the number of shares of Common Stock issued, held in treasury and outstanding, are as follows for the periods indicated: Common Stock Issued Held In Treasury Outstanding (in millions) Balance, December 31, 2016 660.1 230.5 429.6 Common Stock issued 0.0 0.0 0.0 Common Stock acquired 0.0 2.9 (2.9 ) Stock-based compensation programs(1) 0.0 (2.6 ) 2.6 Balance, March 31, 2017 660.1 230.8 429.3 __________ (1) Represents net shares issued from treasury pursuant to the Company’s stock-based compensation program. In December 2016 , Prudential Financial’s Board of Directors authorized the Company to repurchase at management’s discretion up to $1.25 billion of its outstanding Common Stock during the period from January 1, 2017 through December 31, 2017. As of March 31, 2017 , 2.9 million shares of the Company’s Common Stock were repurchased under this authorization at a total cost of $312 million . The timing and amount of share repurchases are determined by management based upon market conditions and other considerations, and repurchases may be effected in the open market, through derivative, accelerated repurchase and other negotiated transactions and through prearranged trading plans complying with Rule 10b5-1(c) under the Securities Exchange Act of 1934 (the “Exchange Act”). Numerous factors could affect the timing and amount of any future repurchases under the share repurchase authorization, including increased capital needs of the Company due to changes in regulatory capital requirements, opportunities for growth and acquisitions, and the effect of adverse market conditions on the segments. Class B Stock From December 18, 2001, the date of demutualization, through December 31, 2014, the Company organized its principal operations into the Financial Services Businesses and the Closed Block Business, and had two classes of common stock outstanding. The Common Stock, which is publicly traded (NYSE: PRU), reflected the performance of the Financial Services Businesses, while the Class B Stock, which was issued through a private placement and did not trade on any exchange, reflected the performance of the Closed Block Business. On January 2, 2015, pursuant to a Share Repurchase Agreement entered into on December 1, 2014, between the Company and the holders of the Class B Stock, the Company repurchased and canceled all of the shares of the Class B Stock for an aggregate cash purchase price of $651 million , resulting in the elimination of the Class B Stock held in treasury, a $484 million decrease in “Retained earnings” and a $167 million decrease in “Additional paid-in capital.” In accordance with the terms of the Share Repurchase Agreement, the holders of the Class B Stock subsequently exercised their right to dispute the calculation of the purchase price. This dispute was resolved during the first quarter of 2016, resulting in an increase to the cash purchase price of $119 million , bringing the total aggregate purchase price to $770 million . The increase to the cash purchase price resulted in a corresponding decrease in “Retained earnings.” Accumulated Other Comprehensive Income (Loss) The balance of and changes in each component of “Accumulated other comprehensive income (loss) attributable to Prudential Financial, Inc.” for the three months ended March 31, 2017 and 2016 , are as follows: Accumulated Other Comprehensive Income (Loss) Attributable to Prudential Financial, Inc.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE A reconciliation of the numerators and denominators of the basic and diluted per share computations of Common Stock based on the consolidated earnings of Prudential Financial for the periods indicated, is as follows: Three Months Ended March 31, 2017 2016 Income Weighted Per Share Income Weighted Per Share (in millions, except per share amounts) Basic earnings per share Net income (loss) $ 1,372 $ 1,369 Less: Income (loss) attributable to noncontrolling interests 3 33 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards 17 15 Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,352 429.9 $ 3.14 $ 1,321 445.3 $ 2.97 Effect of dilutive securities and compensation programs Add: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Basic $ 17 $ 15 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Diluted 16 14 Stock options 2.5 1.4 Deferred and long-term compensation programs 0.9 0.9 Exchangeable Surplus Notes 4 5.8 4 5.6 Diluted earnings per share Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,357 439.1 $ 3.09 $ 1,326 453.2 $ 2.93 Unvested share-based payment awards that contain nonforfeitable rights to dividends are participating securities and included in the computation of earnings per share pursuant to the two-class method. Under this method, earnings attributable to Prudential Financial are allocated between Common Stock and the participating awards, as if the awards were a second class of stock. During periods of net income available to holders of Common Stock, the calculation of earnings per share excludes the income attributable to participating securities in the numerator and the dilutive impact of these securities from the denominator. In the event of a net loss available to holders of Common Stock, undistributed earnings are not allocated to participating securities and the denominator excludes the dilutive impact of these securities as they do not share in the losses of the Company. Undistributed earnings allocated to participating unvested share-based payment awards for the three months ended March 31, 2017 and 2016 , as applicable, were based on 5.3 million and 5.1 million of such awards, respectively, weighted for the period they were outstanding. Stock options and shares related to deferred and long-term compensation programs that are considered antidilutive are excluded from the computation of diluted earnings per share. Stock options are considered antidilutive based on application of the treasury stock method or in the event of a net loss available to holders of Common Stock. Shares related to deferred and long-term compensation programs are considered antidilutive in the event of a net loss available to holders of Common Stock. For the periods indicated, the number of stock options and shares related to deferred and long-term compensation programs that were considered antidilutive and were excluded from the computation of diluted earnings per share, weighted for the portion of the period they were outstanding, are as follows: Three Months Ended March 31, 2017 2016 Shares Exercise Price Shares Exercise Price (in millions, except per share amounts, based on weighted average) Antidilutive stock options based on application of the treasury stock method 0.2 $ 110.45 3.9 $ 83.25 Antidilutive stock options due to net loss available to holders of Common Stock 0.0 0.0 Antidilutive shares based on application of the treasury stock method 0.5 0.0 Antidilutive shares due to net loss available to holders of Common Stock 0.0 0.0 Total antidilutive stock options and shares 0.7 3.9 In September 2009, the Company issued $500 million of surplus notes with an interest rate of 5.36% per annum which are exchangeable at the option of the note holders for shares of Common Stock. The initial exchange rate for the surplus notes was 10.1235 shares of Common Stock per each $1,000 principal amount of surplus notes, which represents an initial exchange price per share of Common Stock of $98.78 ; however, the exchange rate is subject to customary anti-dilution adjustments. In calculating diluted earnings per share under the if-converted method, the potential shares that would be issued assuming a hypothetical exchange, weighted for the period the notes are outstanding, are added to the denominator, and interest expense, net of tax, is added to the numerator, if the overall effect is dilutive.

Prudential Financial and certain subsidiaries have access to other sources of liquidity, including: membership in the Federal Home Loan Banks, commercial paper programs, and a put option agreement. The Company also maintains syndicated, unsecured committed credit facilities as an alternative source of liquidity. At March 31, 2017 , no amounts were drawn on the credit facilities. Long-term Debt The table below presents the Company’s long-term debt as of the dates indicated: March 31, 2017 December 31, 2016 (in millions) Fixed-rate notes: Surplus notes $ 840 $ 840 Surplus notes subject to set-off arrangements(4) 4,503 4,403 Senior notes 9,235 9,236 Mortgage debt(1) 161 177 Floating-rate notes: Surplus notes 499 499 Surplus notes subject to set-off arrangements(4) 1,456 1,456 Senior notes(2) 914 1,063 Mortgage debt(3) 425 409 Junior subordinated notes 5,819 5,817 Subtotal 23,852 23,900 Less: assets under set-off arrangements(4) 5,959 5,859 Total long-term debt(5) $ 17,893 $ 18,041 __________ (1) Includes $66 million and $82 million of debt denominated in foreign currency at March 31, 2017 and December 31, 2016 , respectively. (2) Includes $56 million and $55 million of debt denominated in foreign currency at March 31, 2017 and December 31, 2016 , respectively. (3) Includes $221 million of debt denominated in foreign currency at March 31, 2017 and December 31, 2016 . (4) The surplus notes have corresponding assets where rights to set-off exist, thereby reducing the amount of surplus notes included in long-term debt. (5) Includes Prudential Financial debt of $15,390 million and $15,389 million at March 31, 2017 and December 31, 2016 , respectively. At March 31, 2017 and December 31, 2016 , the Company was in compliance with all debt covenants related to the borrowings in the table above. Surplus Notes During the first quarter of 2017 , the Company established a new $1.0 billion captive financing facility to finance non-economic reserves required under Guideline AXXX. Similar to the Company’s other captive financing facilities, a captive reinsurance subsidiary issues surplus notes under the facility in exchange for credit-linked notes issued by a special-purpose affiliate that are held to support non-economic reserves. The credit-linked notes are redeemable for cash upon the occurrence of a liquidity stress event affecting the captive and external counterparties have agreed to fund these payments. As of March 31, 2017 , $100 million of surplus notes were outstanding under the facility and no credit-linked note payments have been required. Because valid rights of set-off exist, interest and principal payments on the surplus notes and on the credit-linked notes are settled on a net basis, and the surplus notes are reflected in the Company’s total consolidated borrowings on a net basis. Senior Notes Medium-Term Notes. Prudential Financial maintains a medium-term notes program under its shelf registration statement with an authorized issuance capacity of $20.0 billion . As of March 31, 2017 , the outstanding balance of the Company’s medium-term notes was $9.6 billion . Retail Medium-Term Notes. Prudential Financial also maintains a retail medium-term notes program, including the InterNotes ® program, under its shelf registration statement with an authorized issuance capacity of $5.0 billion . As of March 31, 2017 , the outstanding balance of retail notes was $460 million . Mortgage Debt. As of March 31, 2017 , the Company’s subsidiaries had mortgage debt of $659 million that has recourse only to real estate property held for investment by those subsidiaries. The aggregate amount remains unchanged from December 31, 2016, as a prepayment of $41 million was offset by new borrowings of $40 million .

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS Pension and Other Postretirement Plans The Company has funded and non-funded non-contributory defined benefit pension plans (“Pension Benefits”), which cover substantially all of its employees. For some employees, benefits are based on final average earnings and length of service, while benefits for other employees are based on an account balance that takes into consideration age, service and earnings during their career. The Company provides certain health care and life insurance benefits for its retired employees, their beneficiaries and covered dependents (“Other Postretirement Benefits”). The health care plan is contributory; the life insurance plan is non-contributory. Substantially all of the Company’s U.S. employees may become eligible to receive other postretirement benefits if they retire after age 55 with at least 10 years of service or under certain circumstances after age 50 with at least 20 years of continuous service.

Segment Information

Segment Information	3 Months Ended
	Mar. 31, 2017
Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION Segments The Company’s principal operations are comprised of four divisions, which together encompass seven segments, and its Corporate and Other operations. The U.S. Retirement Solutions and Investment Management division consists of the Individual Annuities, Retirement and Asset Management segments. The U.S. Individual Life and Group Insurance division consists of the Individual Life and Group Insurance segments. The International Insurance division consists of the International Insurance segment. The Closed Block division consists of the Closed Block segment. The Closed Block division is accounted for as a divested business that is reported separately from the divested businesses that are included in Corporate and Other operations. Our Corporate and Other operations include corporate items and initiatives that are not allocated to business segments and businesses that have been or will be divested. Adjusted Operating Income The Company analyzes the operating performance of each segment using “adjusted operating income.” Adjusted operating income does not equate to “Income (loss) before income taxes and equity in earnings of operating joint ventures” or “Net income (loss)” as determined in accordance with U.S. GAAP but is the measure of segment profit or loss used by the Company’s chief operating decision maker to evaluate segment performance and allocate resources, and consistent with authoritative guidance, is the measure of segment performance presented below. Adjusted operating income is calculated by adjusting each segment’s “Income (loss) before income taxes and equity in earnings of operating joint ventures” for the following items, which are described in greater detail below: • realized investment gains (losses), net, and related charges and adjustments; • net investment gains (losses) on trading account assets supporting insurance liabilities and changes in experience-rated contractholder liabilities due to asset value changes; • the contribution to income (loss) of divested businesses that have been or will be sold or exited, including businesses that have been placed in wind down status, but that did not qualify for “discontinued operations” accounting treatment under U.S. GAAP; and • equity in earnings of operating joint ventures and earnings attributable to noncontrolling interests. These items are important to an understanding of overall results of operations. Adjusted operating income is not a substitute for income determined in accordance with U.S. GAAP, and the Company’s definition of adjusted operating income may differ from that used by other companies. However, the Company believes that the presentation of adjusted operating income as measured for management purposes enhances the understanding of results of operations by highlighting the results from ongoing operations and the underlying profitability factors of its businesses. Realized investment gains (losses), net, and related charges and adjustments Realized investment gains (losses), net Adjusted operating income excludes “Realized investment gains (losses), net,” except for certain items described below. Significant activity excluded from adjusted operating income includes impairments and credit-related gains (losses) from sales of securities, the timing of which depends largely on market credit cycles and can vary considerably across periods, and interest rate-related gains (losses) from sales of securities, which are largely subject to the Company’s discretion and influenced by market opportunities, as well as the Company’s tax and capital profile. Additionally, adjusted operating income generally excludes realized investment gains and losses from products that contain embedded derivatives, and from associated derivative portfolios that are part of an asset liability management program related to the risk of those products. However, the effectiveness of the hedging program will ultimately be reflected in adjusted operating income over time. Trends in the underlying profitability of the Company’s businesses can be more clearly identified without the fluctuating effects of these transactions. The following table sets forth the significant components of “Realized investment gains (losses), net” that are included in adjusted operating income and, as a result, are reflected as adjustments to “Realized investment gains (losses), net” for purposes of calculating adjusted operating income: Three Months Ended 2017 2016 (in millions) Net gains (losses) from(1): Terminated hedges of foreign currency earnings $ 1 $ 36 Current period yield adjustments $ 121 $ 127 Principal source of earnings $ (8 ) $ 10 __________ (1) In addition to the items in the table above, “Realized investment gains (losses), net, and related charges and adjustments” also includes an adjustment to reflect “Realized investment gains (losses), net” related to divested businesses as results of “Divested businesses,” discussed below. Terminated Hedges of Foreign Currency Earnings. The amounts shown in the table above primarily reflect the impact of an intercompany arrangement between Corporate and Other operations and the International Insurance segment, pursuant to which non-U.S. dollar-denominated earnings for a particular year, including its interim reporting periods, are translated at fixed currency exchange rates. The fixed rates are determined in connection with a currency hedging program designed to mitigate the risk that unfavorable rate changes will reduce the segment’s U.S. dollar-equivalent earnings. Pursuant to this program, the Company’s Corporate and Other operations may execute forward currency contracts with third parties to sell the net exposure of projected earnings from the hedged currency in exchange for U.S. dollars at a specified exchange rate. The maturities of these contracts correspond with the future periods in which the identified non-U.S. dollar-denominated earnings are expected to be generated. These contracts do not qualify for hedge accounting under U.S. GAAP, so the resulting profits or losses are recorded in “Realized investment gains (losses), net.” When the contracts are terminated in the same period that the expected earnings emerge, the resulting positive or negative cash flow effect is included in adjusted operating income. Current Period Yield Adjustments. The Company uses interest rate and currency swaps and other derivatives to manage interest and currency exchange rate exposures arising from mismatches between assets and liabilities, including duration mismatches. For derivative contracts that do not qualify for hedge accounting treatment, the periodic swap settlements, as well as certain other derivative related yield adjustments are recorded in “Realized investment gains (losses), net,” and are included in adjusted operating income to reflect the after-hedge yield of the underlying instruments. In certain instances, when these derivative contracts are terminated or offset before their final maturity, the resulting realized gains or losses are recognized in adjusted operating income over periods that generally approximate the expected terms of the derivatives or underlying instruments in order for adjusted operating income to reflect the after-hedge yield of the underlying instruments. Included in the amounts shown in the table above are gains on certain derivative contracts that were terminated or offset before their final maturity of $14 million and $12 million for the three months ended March 31, 2017 and 2016 , respectively. As of March 31, 2017 , there was a $136 million deferred net gain related to certain derivative contracts that were terminated or offset before their final maturity, primarily in the International Insurance segment. Also included in the amounts shown in the table above are fees related to synthetic Guaranteed Investment Contracts (“GICs”) of $40 million and $39 million for the three months ended March 31, 2017 and 2016 , respectively. Synthetic GICs are accounted for as derivatives under U.S. GAAP and, therefore, these fees are recorded in “Realized investment gains (losses), net.” See Note 14 for additional information on synthetic GICs. Principal Source of Earnings. The Company conducts certain activities for which realized investment gains (losses) are a principal source of earnings for its businesses and therefore included in adjusted operating income, particularly within the Company’s Asset Management segment. For example, Asset Management’s strategic investing business makes investments for sale or syndication to other investors or for placement or co-investment in the Company’s managed funds and structured products. The realized investment gains (losses) associated with the sale of these strategic investments, as well as the majority of derivative results, are a principal activity for this business and included in adjusted operating income. In addition, the realized investment gains (losses) associated with loans originated by the Company’s commercial mortgage operations, as well as related derivative results and retained mortgage servicing rights, are a principal activity for this business and included in adjusted operating income. Other items reflected as adjustments to Realized investment gains (losses), net The following table sets forth certain other items excluded from adjusted operating income and reflected as an adjustment to “Realized investment gains (losses), net” for purposes of calculating adjusted operating income: Three Months Ended 2017 2016 (in millions) Net gains (losses) from: Other trading account assets $ 33 $ (22 ) Foreign currency exchange movements $ (127 ) $ (321 ) Other activities $ 1 $ 3 Other Trading Account Assets. The Company has certain investments in its general account portfolios that are classified as trading. These trading investments are carried at fair value and included in “Other trading account assets, at fair value” on the Company’s Unaudited Interim Consolidated Statements of Financial Position. Realized and unrealized gains (losses) for these investments are recorded in “Other income.” Consistent with the exclusion of realized investment gains (losses) with respect to other investments managed on a consistent basis, the net gains or losses on these investments are excluded from adjusted operating income. Foreign Currency Exchange Movements. The Company has certain assets and liabilities for which, under U.S. GAAP, the changes in value, including those associated with changes in foreign currency exchange rates during the period, are recorded in “Other income.” To the extent the foreign currency exposure on these assets and liabilities is economically hedged or considered part of the Company’s capital funding strategies for its international subsidiaries, the change in value included in “Other income” is excluded from adjusted operating income. Other Activities. The Company excludes certain other items from adjusted operating income that are consistent with similar adjustments described above. Related charges Charges that relate to realized investment gains (losses) are also excluded from adjusted operating income, and include the following: • The portion of the amortization of DAC, VOBA, unearned revenue reserves and DSI for certain products that is related to net realized investment gains (losses). • Policyholder dividends and interest credited to policyholders’ account balances that relate to certain life policies that pass back certain realized investment gains (losses) to the policyholder, and reserves for future policy benefits for certain policies that are affected by net realized investment gains (losses). • Market value adjustments paid or received upon a contractholder’s surrender of certain of the Company’s annuity products as these amounts mitigate the net realized investment gains or losses incurred upon the disposition of the underlying invested assets. Investment gains (losses) on trading account assets supporting insurance liabilities and changes in experience-rated contractholder liabilities due to asset value changes Certain products included in the Retirement and International Insurance segments are experience-rated in that investment results associated with these products are expected to ultimately accrue to contractholders. The majority of investments supporting these experience-rated products are classified as trading and are carried at fair value, with realized and unrealized gains (losses) reported in “Other income.” To a lesser extent, these experience-rated products are also supported by derivatives and commercial mortgage and other loans. The derivatives are carried at fair value, with realized and unrealized gains (losses) reported in “Realized investment gains (losses), net.” The commercial mortgage and other loans are carried at unpaid principal, net of unamortized discounts and an allowance for losses, with gains (losses) on sales and changes in the valuation allowance for commercial mortgage and other loans reported in “Realized investment gains (losses), net.” Adjusted operating income excludes net investment gains (losses) on trading account assets supporting insurance liabilities, which is consistent with the exclusion of realized investment gains (losses) with respect to other investments supporting insurance liabilities managed on a consistent basis. In addition, to be consistent with the historical treatment of charges related to realized investment gains (losses) on investments, adjusted operating income also excludes the change in contractholder liabilities due to asset value changes in the pool of investments (including changes in the fair value of commercial mortgage and other loans) supporting these experience-rated contracts, which are reflected in “Interest credited to policyholders’ account balances.” These adjustments are in addition to the exclusion from adjusted operating income of net investment gains (losses) on the related derivatives and commercial mortgage and other loans through “Realized investment gains (losses), net, and related charges and adjustments,” as discussed above. The result of this approach is that adjusted operating income for these products includes net fee revenue and interest spread the Company earns on these experience-rated contracts, and excludes changes in fair value of the pool of investments, both realized and unrealized, that are expected to ultimately accrue to the contractholders. Divested businesses The contribution to income (loss) of divested businesses that have been or will be sold or exited, including businesses that have been placed in wind down, but that did not qualify for “discontinued operations” accounting treatment under U.S. GAAP, are excluded from adjusted operating income as the results of divested businesses are not considered relevant to understanding the Company’s ongoing operating results. Equity in earnings of operating joint ventures and earnings attributable to noncontrolling interests Equity in earnings of operating joint ventures, on a pre-tax basis, are included in adjusted operating income as these results are a principal source of earnings. These earnings are reflected on a U.S. GAAP basis on an after-tax basis as a separate line on the Company’s Unaudited Interim Consolidated Statements of Operations. Earnings attributable to noncontrolling interests are excluded from adjusted operating income. Earnings attributable to noncontrolling interests represents the portion of earnings from consolidated entities that relates to the equity interests of minority investors, and are reflected on a U.S. GAAP basis as a separate line on the Company’s Unaudited Interim Consolidated Statements of Operations.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company uses a full year projected effective tax rate approach to calculate taxes at interim periods. In addition, certain items impacting total income tax expense are recorded in the periods in which they occur. The projected effective tax rate is the ratio of projected “Total income tax expense” divided by projected “Income before income taxes and equity in earnings of operating joint ventures.” Taxes attributable to operating joint ventures are recorded within “Equity in earnings of operating joint ventures, net of taxes.” Our income tax provision, on a consolidated basis, amounted to an income tax expense of $395 million , or 22.7% of income (loss) before income taxes and equity in earnings of operating joint ventures, in the first quarter of 2017, compared to $368 million , or 21.2% of income (loss) before income taxes and equity in earnings of operating joint ventures in the first quarter of 2016. The Company’s current and prior effective tax rates differed from the U.S. statutory rate of 35% primarily due to non-taxable investment income, tax credits, and foreign earnings taxed at lower rates than the U.S. statutory rate. In addition, the first quarter of 2017 also includes a $21 million tax benefit, as a result of the Company’s adoption of ASU 2016-09 regarding employee share-based payments. Under prior guidance, such tax benefits related to employee share-based payments would have been reported in “Additional paid-in capital.” See Note 2 for additional information.

Fair Value of Assets and Liabil

Fair Value of Assets and Liabilities	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	FAIR VALUE OF ASSETS AND LIABILITIES Fair Value Measurement —Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative fair value guidance establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows: Level 1—Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities. The Company’s Level 1 assets and liabilities primarily include certain cash equivalents and short-term investments, equity securities and derivative contracts that trade on an active exchange market. Level 2—Fair value is based on significant inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, and other market observable inputs. The Company’s Level 2 assets and liabilities include: fixed maturities (corporate public and private bonds, most government securities, certain asset-backed and mortgage-backed securities, etc.), certain equity securities (mutual funds, which do not trade in active markets because they are not publicly available), certain commercial mortgage loans, short-term investments and certain cash equivalents (primarily commercial paper), and certain OTC derivatives. Level 3—Fair value is based on at least one significant unobservable input for the asset or liability. The assets and liabilities in this category may require significant judgment or estimation in determining the fair value. The Company’s Level 3 assets and liabilities primarily include: certain private fixed maturities and equity securities, certain manually priced public equity securities and fixed maturities, certain highly structured OTC derivative contracts, certain commercial mortgage loans, certain consolidated real estate funds for which the Company is the general partner and embedded derivatives resulting from certain products with guaranteed benefits.

(2) Excludes notes with fair value of $1,556 million and $1,456 million as of March 31, 2017 and December 31, 2016 , respectively, which have been offset with the associated payables under a netting agreement. (3) Includes credit-tranched securities collateralized by sub-prime mortgages, auto loans, credit cards, education loans and other asset types. (4) Includes “Trading account assets supporting insurance liabilities” and “Other trading account assets.” (5) Level 1 represents cash equivalents and short term investments. All other amounts primarily represent derivative assets. (6) Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company’s Unaudited Interim Consolidated Statements of Financial Position. (7) As of March 31, 2017 , the net embedded derivative liability position of $7.6 billion includes $1.3 billion of embedded derivatives in an asset position and $8.9 billion of embedded derivatives in a liability position. As of December 31, 2016 , the net embedded derivative liability position of $8.2 billion includes $1.2 billion of embedded derivatives in an asset position and $9.4 billion of embedded derivatives in a liability position. The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below. Fixed Maturity Securities —The fair values of the Company’s public fixed maturity securities are generally based on prices obtained from independent pricing services. Prices for each security are generally sourced from multiple pricing vendors, and a vendor hierarchy is maintained by asset type based on historical pricing experience and vendor expertise. The Company ultimately uses the price from the pricing service highest in the vendor hierarchy based on the respective asset type. The pricing hierarchy is updated for new financial products and recent pricing experience with various vendors. Consistent with the fair value hierarchy described above, securities with validated quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. Typical inputs used by these pricing services include but are not limited to, reported trades, benchmark yields, issuer spreads, bids, offers, and/or estimated cash flow, prepayment speeds and default rates. If the pricing information received from third-party pricing services is deemed not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process with the pricing service or classify the securities as Level 3. If the pricing service updates the price to be more consistent with the presented market observations, the security remains within Level 2. Internally-developed valuations or indicative broker quotes are also used to determine fair value in circumstances where vendor pricing is not available, or where the Company ultimately concludes that pricing information received from the independent pricing services is not reflective of market activity. If the Company concludes the values from both pricing services and brokers are not reflective of market activity, it may override the information with an internally-developed valuation. As of March 31, 2017 and December 31, 2016 , overrides on a net basis were not material. Pricing service overrides, internally-developed valuations and indicative broker quotes are generally included in Level 3 in the fair value hierarchy. The Company conducts several specific price monitoring activities. Daily analyses identify price changes over predetermined thresholds defined at the financial instrument level. Various pricing integrity reports are reviewed on a daily and monthly basis to determine if pricing is reflective of market activity or if it would warrant any adjustments. Other procedures performed include, but are not limited to, reviews of third-party pricing services methodologies, reviews of pricing trends and back testing. The fair value of private fixed maturities, which are comprised of investments in private placement securities, originated by internal private asset managers, are primarily determined using discounted cash flow models. These models primarily use observable inputs that include Treasury or similar base rates plus estimated credit spreads to value each security. The credit spreads are obtained through a survey of private market intermediaries who are active in both primary and secondary transactions, and consider, among other factors, the credit quality and industry sector of the issuer and the reduced liquidity associated with private placements. Since most private placements are valued using standard market observable inputs and inputs derived from, or corroborated by, market observable data including observed prices and spreads for similar publicly-traded or privately-traded issues, they have been reflected within Level 2. For certain private fixed maturities, the discounted cash flow model may incorporate significant unobservable inputs, which reflect the Company’s own assumptions about the inputs that market participants would use in pricing the asset. To the extent management determines that such unobservable inputs are significant to the price of a security, a Level 3 classification is made. Trading Account Assets —Trading account assets consist primarily of fixed maturity securities, equity securities and derivatives whose fair values are determined consistent with similar instruments described above under “Fixed Maturity Securities” and below under “Equity Securities” and “Derivative Instruments.” Equity Securities —Equity securities consist principally of investments in common and preferred stock of publicly-traded companies, perpetual preferred stock, privately-traded securities, as well as mutual fund shares. The fair values of most publicly- traded equity securities are based on quoted market prices in active markets for identical assets and are classified within Level 1 in the fair value hierarchy. Estimated fair values for most privately traded equity securities are determined using discounted cash flow, earnings multiple and other valuation models that require a substantial level of judgment around inputs and therefore are classified within Level 3. The fair values of mutual fund shares that transact regularly (but do not trade in active markets because they are not publicly available) are based on transaction prices of identical fund shares and are classified within Level 2 in the fair value hierarchy. The fair values of perpetual preferred stock are based on inputs obtained from independent pricing services that are primarily based on indicative broker quotes. As a result, the fair values of perpetual preferred stock are classified as Level 3. Commercial Mortgage and Other Loans —The fair value of loans held and accounted for using the fair value option is determined utilizing pricing indicators from the whole loan market, where investors are committed to purchase these loans at a predetermined price, which is considered the principal exit market for these loans. The Company evaluates the valuation inputs used for these assets, including the existence of predetermined exit prices, the terms of the loans, prevailing interest rates and credit risk, and deems the primary pricing inputs are Level 2 inputs in the fair value hierarchy. Other Long-Term Investments —Other long-term investments shown in the hierarchy table include limited partnerships which are consolidated because the Company is either deemed to exercise control or considered the primary beneficiary of a variable interest entity. These entities are primarily investment companies and follow specialized industry accounting whereby their assets are carried at fair value. The investments held by these entities include various feeder fund investments in underlying master funds (whose underlying holdings generally include public fixed maturities, equity securities and mutual funds), as well as wholly-owned real estate held within other investment funds. For the unconsolidated fund investments, where the Company has elected the fair value option, the fair value is primarily determined by the fund managers and is measured at net asset value (“NAV”) as a practical expedient. Other long-term investments excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measure at NAV per share (or its equivalent). At March 31, 2017 and December 31, 2016 , the fair values of such investments were $1,771 million and $1,579 million , respectively. Other Assets —Other assets reflected in Level 3 include reinsurance recoverables which are carried at fair value and relate to the reinsurance of the Company’s living benefit guarantees on certain variable annuity contracts. The methods and assumptions used to estimate the fair value are consistent with those described in “Future Policy Benefits.” Derivative Instruments —Derivatives are recorded at fair value either as assets, within “Other trading account assets,” or “Other long-term investments,” or as liabilities, within “Other liabilities,” except for embedded derivatives which are recorded with the associated host contract. The fair values of derivative contracts can be affected by changes in interest rates, foreign exchange rates, commodity prices, credit spreads, market volatility, expected returns, non-performance risk (“NPR”), liquidity and other factors. For derivative positions included within Level 3 of the fair value hierarchy, liquidity valuation adjustments are made to reflect the cost of exiting significant risk positions, and consider the bid-ask spread, maturity, complexity and other specific attributes of the underlying derivative position. The Company’s exchange-traded futures and options include Treasury futures, Eurodollar futures, commodity futures, Eurodollar options and commodity options. Exchange-traded futures and options are valued using quoted prices in active markets and are classified within Level 1 in the fair value hierarchy. The majority of the Company’s derivative positions are traded in the OTC derivative market and are classified within Level 2 in the fair value hierarchy. OTC derivatives classified within Level 2 are valued using models that utilize actively quoted or observable market input values from external market data providers, third-party pricing vendors and/or recent trading activity. The Company’s policy is to use mid-market pricing in determining its best estimate of fair value. The fair values of most OTC derivatives, including interest rate and cross-currency swaps, currency forward contracts, commodity swaps, commodity forward contracts, single name credit default swaps, loan commitments held for sale and “to be announced” (“TBA”) forward contracts on highly rated mortgage-backed securities issued by U.S. government sponsored entities are determined using discounted cash flow models. The fair values of European style option contracts are determined using Black-Scholes option pricing models. These models’ key inputs include the contractual terms of the respective contract, along with significant observable inputs, including interest rates, currency rates, credit spreads, equity prices, index dividend yields, NPR, volatility and other factors. The Company’s cleared interest rate swaps and credit derivatives linked to an index are valued using models that utilize actively quoted or observable market inputs, including Overnight Indexed Swap discount rates, obtained from external market data providers, third-party pricing vendors and/or recent trading activity. These derivatives are classified as Level 2 in the fair value hierarchy. The vast majority of the Company’s derivative agreements are with highly rated major international financial institutions. To reflect the market’s perception of its own and the counterparty’s NPR, the Company incorporates additional spreads over London Inter-Bank Offered Rate (“LIBOR”) into the discount rate used in determining the fair value of OTC derivative assets and liabilities that are not otherwise collateralized. Derivatives classified as Level 3 include look-back equity options and other structured products. These derivatives are valued based upon models, such as Monte Carlo simulation models and other techniques that utilize significant unobservable inputs. Level 3 methodologies are validated through periodic comparison of the Company’s fair values to external broker-dealer values. Cash Equivalents and Short-Term Investments —Cash equivalents and short-term investments include money market instruments, commercial paper and other highly liquid debt instruments. Certain money market instruments are valued using unadjusted quoted prices in active markets that are accessible for identical assets and are primarily classified as Level 1. The remaining instruments in this category are generally fair valued based on market observable inputs and these investments have primarily been classified within Level 2. Separate Account Assets —Separate account assets shown in the hierarchy table include fixed maturity securities, treasuries, equity securities and mutual funds for which values are determined consistent with similar instruments described above under “Fixed Maturity Securities,” and “Equity Securities.” Separate account assets included in the fair value hierarchy, excludes investments in entities that calculate net asset value per share (or its equivalent). Such investments excluded from the fair value hierarchy, include real estate, hedge funds and other invested assets. At March 31, 2017 and December 31, 2016 , the fair value of such investments were $25,543 million and $25,619 million , respectively. Notes issued by Consolidated VIEs —These notes are based on the fair values of corresponding bank loan collateral. Since the notes are valued based on reference collateral, they are classified as Level 3. See Note 5 and “Fair Value Option” below for additional information. Other Liabilities —Other liabilities include certain derivative instruments, including embedded derivatives associated with certain “Policyholders’ account balances.” The fair values are primarily determined consistent with similar derivative instruments described above under “Derivative Instruments.” Future Policy Benefits —The liability for future policy benefits is related to guarantees primarily associated with the living benefit features of certain variable annuity contracts offered by the Company’s Individual Annuities segment, including guaranteed minimum accumulation benefits, guaranteed minimum withdrawal benefits and guaranteed minimum income and withdrawal benefits, accounted for as embedded derivatives. The fair values of these liabilities are calculated as the present value of future expected benefit payments to customers less the present value of future expected rider fees attributable to the embedded derivative feature. This methodology could result in either a liability or contra-liability balance, given changing capital market conditions and various actuarial assumptions. Since there is no observable active market for the transfer of these obligations, the valuations are calculated using internally-developed models with option pricing techniques. The models are based on a risk neutral valuation framework and incorporate premiums for risks inherent in valuation techniques, inputs, and the general uncertainty around the timing and amount of future cash flows. The determination of these risk premiums requires the use of management’s judgment. The significant inputs to the valuation models for these embedded derivatives include capital market assumptions, such as interest rate levels and volatility assumptions, the Company’s market-perceived NPR, as well as actuarially determined assumptions, including contractholder behavior, such as lapse rates, benefit utilization rates, withdrawal rates, and mortality rates. Since many of these assumptions are unobservable and are considered to be significant inputs to the liability valuation, the liability included in future policy benefits has been reflected within Level 3 in the fair value hierarchy . Capital market inputs and actual policyholders’ account values are updated each quarter based on capital market conditions as of the end of the quarter, including interest rates, equity markets and volatility. In the risk neutral valuation, the initial swap curve drives the total return used to grow the policyholders’ account values. The Company’s discount rate assumption is based on the LIBOR swap curve adjusted for an additional spread relative to LIBOR to reflect NPR. Actuarial assumptions, including contractholder behavior and mortality, are reviewed at least annually, and updated based upon emerging experience, future expectations and other data, including any observable market data. These assumptions are generally updated annually unless a material change that the Company feels is indicative of a long-term trend is observed in an interim period. Transfers between Levels 1 and 2 —Transfers between levels are made to reflect changes in observability of inputs and market activity. Transfers into or out of any level are generally reported as the value as of the beginning of the quarter in which the transfers occur for any such assets still held at the end of the quarter. Periodically there are transfers between Level 1 and Level 2 for assets held in the Company’s Separate Account. The fair value of foreign common stock held in the Company’s Separate Account may reflect differences in market levels between the close of foreign trading markets and the close of U.S. trading markets for the respective day. Dependent on the existence of such a timing difference, the assets may move between Level 1 and Level 2. During the three months ended March 31, 2017 , $46 million were transferred from Level 1 to Level 2 and $57 million were transferred from Level 2 to Level 1. During the three months ended March 31, 2016 , $254 million were transferred from Level 1 to Level 2 and $18 million were transferred from Level 2 to Level 1.

Quantitative Information Regarding Internally-Priced Level 3 Assets and Liabilities —The tables below present quantitative information on significant internally-priced Level 3 assets and liabilities (see narrative below for quantitative information for separate account assets). As of March 31, 2017 Fair Value Valuation Techniques Unobservable Inputs Minimum Maximum Weighted Average Impact of Increase in Input on Fair Value(1) (in millions) Assets: Corporate securities(2) $ 1,916 Discounted cash flow Discount rate 0.66% - 20% 5.96% Decrease Liquidation Liquidation value 15.93% - 16.10% 16.02% Increase Liabilities: Future policy benefits(4) $ 7,640 Discounted cash flow Lapse rate(5) 0% - 13% Decrease NPR spread(6) 0.19% - 1.42% Decrease Utilization rate(7) 52% - 96% Increase Withdrawal rate See table footnote (8) below.

Mortality rate(9) 0% - 14% Decrease Equity volatility curve 16% - 25% Increase __________ (1) Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table. (2) Includes assets classified as fixed maturities available-for-sale, trading account assets supporting insurance liabilities and other trading account assets. (3) Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments. (4) Future policy benefits primarily represent general account liabilities for the living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (5) Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. (6) To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of individual living benefit contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. (7) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (8) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions vary based on the age of the contractholder, the tax status of the contract and the d

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS Types of Derivative Instruments and Derivative Strategies Interest Rate Contracts Interest rate swaps, options and futures are used by the Company to reduce risks from changes in interest rates, manage interest rate exposures arising from mismatches between assets and liabilities (including duration mismatches) and to hedge against changes in the value of assets it owns or anticipates acquiring or selling. Swaps may be attributed to specific assets or liabilities or may be used on a portfolio basis. Under interest rate swaps, the Company agrees with counterparties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed upon notional principal amount. The Company also uses swaptions, interest rate caps and interest rate floors to manage interest rate risk. A swaption is an option to enter into a swap at a future date. The Company pays a premium for purchased swaptions and receives a premium for written swaptions. In an interest rate cap, the buyer receives payments at the end of each period in which the interest rate exceeds the agreed strike price. Similarly, in an interest rate floor, the buyer receives payments at the end of each period in which the interest rate is below the agreed strike price. Swaptions and interest rate caps and floors are included in interest rate options. In exchange-traded interest rate futures transactions, the Company purchases or sells a specified number of contracts, the values of which are determined by the values of underlying referenced investments, and posts variation margin on a daily basis in an amount equal to the difference in the daily market values of those contracts. The Company enters into exchange-traded futures with regulated futures commission’s merchants who are members of a trading exchange. Equity Contracts Equity index options are contracts which will settle in cash based on differentials in the underlying indices at the time of exercise and the strike price. The Company uses combinations of purchases and sales of equity index options to hedge the effects of adverse changes in equity indices within a predetermined range. Total return swaps are contracts whereby the Company agrees with counterparties to exchange, at specified intervals, the difference between the return on an asset (or market index) and LIBOR plus an associated funding spread based on a notional amount. The Company generally uses total return swaps to hedge the effect of adverse changes in equity indices. Foreign Exchange Contracts Currency derivatives, including currency futures, options, forwards and swaps, are contracts used by the Company to reduce risks from changes in currency exchange rates with respect to investments denominated in foreign currencies that the Company either holds or intends to acquire or sell, and to hedge the currency risk associated with net investments in foreign operations and anticipated earnings of its foreign operations. Under currency forwards, the Company agrees with counterparties to deliver a specified amount of an identified currency at a specified future date. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. As noted above, the Company uses currency forwards to mitigate the impact of changes in currency exchange rates on U.S. dollar equivalent earnings generated by certain of its non-U.S. businesses, primarily its international insurance and investment operations. The Company executes forward sales of the hedged currency in exchange for U.S. dollars at a specified exchange rate. The maturities of these forwards correspond with the future periods in which the non-U.S. dollar-denominated earnings are expected to be generated. These earnings hedges do not qualify for hedge accounting. Under currency swaps, the Company agrees with counterparties to exchange, at specified intervals, the difference between one currency and another at an exchange rate and calculated by reference to an agreed principal amount and corresponding currency interest rate. Generally, the principal amount of each currency is exchanged at the beginning and termination of the currency swap by each party. Credit Contracts The Company writes credit default swaps for which it receives a premium to insure credit risk. These are used by the Company to enhance the return on the Company’s investment portfolio by creating credit exposure similar to an investment in public fixed maturity cash instruments. With these derivatives the Company sells credit protection on a single name reference, or certain index reference, and in return receives a quarterly premium. This premium or credit spread generally corresponds to the difference between the yield on the referenced names (or an index’s referenced names) public fixed maturity cash instruments and swap rates, at the time the agreement is executed. If there is an event of default by the referenced name or one of the referenced names in the index, as defined by the agreement, then the Company is obligated to pay the referenced amount of the contract to the counterparty and receive in return the referenced defaulted security or similar security or (in the case of a credit default index) pay the referenced amount less the auction recovery rate. See credit derivatives written section for further discussion of guarantees. In addition to selling credit protection, the Company has purchased credit protection using credit derivatives in order to hedge specific credit exposures in the Company’s investment portfolio. Other Contracts TBAs. The Company uses TBA forward contracts to gain exposure to the investment risk and return of mortgage-backed securities. TBA transactions can help the Company enhance the return on its investment portfolio, and can provide a more liquid and cost effective method of achieving these goals than purchasing or selling individual mortgage-backed pools. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at a specified future date. Additionally, pursuant to the Company’s mortgage dollar roll program, TBAs or mortgage-backed securities are transferred to counterparties with a corresponding agreement to repurchase them at a future date. These transactions do not qualify as secured borrowings and are accounted for as derivatives. Loan Commitments. In its mortgage operations, the Company enters into commitments to fund commercial mortgage loans at specified interest rates and other applicable terms within specified periods of time. These commitments are legally binding agreements to extend credit to a counterparty. Loan commitments for loans that will be held for sale are recognized as derivatives and recorded at fair value. The determination of the fair value of loan commitments accounted for as derivatives considers various factors including, among others, terms of the related loan, the intended exit strategy for the loans based upon either securitization valuation models or investor purchase commitments, prevailing interest rates, origination income or expense, and the value of service rights. Loan commitments that relate to the origination of mortgage loans that will be held for investment are not accounted for as derivatives and accordingly are not recognized in the Company’s financial statements. See Note 15 for additional information. Embedded Derivatives. The Company sells variable annuity products, which may include guaranteed benefit features that are accounted for as embedded derivatives. These embedded derivatives are marked to market through “Realized investment gains (losses), net” based on the change in value of the underlying contractual guarantees, which are determined using valuation models. The Company maintains a portfolio of derivative instruments that is intended to offset certain risks related to the above products’ features. The derivatives may include, but are not limited to equity options, total return swaps, interest rate swaptions, caps, floors and other instruments. Synthetic Guarantees. The Company sells synthetic GICs, through both full service and investment-only sales channels, to investment vehicles primarily used by qualified defined contribution pension plans. The synthetic GICs are issued in respect of assets that are owned by the trustees of such plans, who invest the assets according to the contract terms agreed to with the Company. The contracts establish participant balances and credit interest thereon. The participant balances are supported by the underlying assets. In connection with certain participant-initiated withdrawals, the contract guarantees that after all underlying assets are liquidated, any remaining participant balances will be paid by the Company. Under U.S. GAAP, these contracts are accounted for as derivatives and recorded at fair value. Primary Risks Managed by Derivatives The table below provides a summary of the gross notional amount and fair value of derivatives contracts by the primary underlying, excluding embedded derivatives and associated reinsurance recoverables. Many derivative instruments contain multiple underlyings. The fair value amounts below represent the gross fair value of derivative contracts prior to taking into account the netting effects of master netting agreements, cash collateral and NPR. This netting impact results in total derivative assets of $1,147 million and $1,367 million as of March 31, 2017 and December 31, 2016 , respectively, and total derivative liabilities of $203 million and $345 million as of March 31, 2017 and December 31, 2016 , respectively, reflected in the Unaudited Interim Consolidated Statements of Financial Position. Based on notional amounts, most of the Company’s derivatives do not qualify for hedge accounting as follows: i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income, ii) derivatives that are utilized as macro hedges of the Company’s exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules, and iii) synthetic GICs, which are product standalone derivatives, do not qualify as hedging instruments under hedge accounting rules.

For information regarding the rights of offset associated with the derivative assets and liabilities in the table above, see “—Counterparty Credit Risk” below. For securities purchased under agreements to resell and securities sold under agreements to repurchase, the Company monitors the value of the securities and maintains collateral, as appropriate, to protect against credit exposure. Where the Company has entered into repurchase and resale agreements with the same counterparty, in the event of default, the Company would generally be permitted to exercise rights of offset. For additional information on the Company’s accounting policy for securities repurchase and resale agreements, see Note 2 to the Company’s Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2016 . Cash Flow, Fair Value and Net Investment Hedges The primary derivative instruments used by the Company in its fair value, cash flow and net investment hedge accounting relationships are interest rate swaps, currency swaps and currency forwards. These instruments are only designated for hedge accounting in instances where the appropriate criteria are met. The Company does not use futures, options, credit, equity or embedded derivatives in any of its fair value, cash flow or net investment hedge accounting relationships. The following table provides the financial statement classification and impact of derivatives used in qualifying and non-qualifying hedge relationships, excluding the offset of the hedged item in an effective hedge relationship.

For the three months ended March 31, 2017 and 2016 , the ineffective portion of derivatives accounted for using hedge accounting was not material to the Company’s results of operations. Also, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging. In addition, there were no instances in which the Company discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge. Presented below is a rollforward of current period cash flow hedges in AOCI before taxes: (in millions) Balance, December 31, 2016 $ 1,316 Net deferred gains (losses) on cash flow hedges from January 1 to March 31, 2017 (138 ) Amount reclassified into current period earnings (60 ) Balance, March 31, 2017 $ 1,118 Using March 31, 2017 values, it is estimated that a pre-tax gain of approximately $170 million will be reclassified from AOCI to earnings during the subsequent twelve months ending March 31, 2018 , offset by amounts pertaining to the hedged items. As of March 31, 2017 , the Company does not have any qualifying cash flow hedges of forecasted transactions other than those related to the variability of the payment or receipt of interest or foreign currency amounts on existing financial instruments. The maximum length of time for which these variable cash flows are hedged is 40 years . Income amounts deferred in AOCI as a result of cash flow hedges are included in “Net unrealized investment gains (losses)” in the Unaudited Interim Consolidated Statements of Comprehensive Income. For effective net investment hedges, the amounts, before applicable taxes, recorded in the cumulative translation adjustment account within AOCI were $533 million and $536 million as of March 31, 2017 and December 31, 2016 , respectively. Credit Derivatives Credit derivatives, where the Company has written credit protection on a single name reference, had outstanding notional amounts of $109 million and $ 112 million as of March 31, 2017 and December 31, 2016 , respectively. These credit derivatives are reported at fair value as an asset of $1 million and an asset of less than $1 million as of March 31, 2017 and December 31, 2016 , respectively. As of March 31, 2017 , these credit derivatives’ notionals had the following NAIC ratings: $ 48 million in NAIC 1; $ 48 million in NAIC 2; $5 million in NAIC 3; $1 million in NAIC 4; $3 million in NAIC 5; and $4 million in NAIC 6. The Company has also written credit protection on certain index references with notional amounts of $50 million reported at fair value as a liability of less than $1 million as of both March 31, 2017 and December 31, 2016 . As of March 31, 2017 , these credit derivatives’ notional amounts of $ 50 million had a NAIC rating of NAIC 1. NAIC designations are based on the lowest rated single name reference included in the index. The Company’s maximum amount at risk under these credit derivatives equals the aforementioned notional amounts and assumes the value of the underlying referenced securities become worthless. These single name credit derivatives have maturities of less than 4 years , while the credit protection on the index references have maturities of less than 30 years . This excludes a credit derivative related to surplus notes issued by a subsidiary of Prudential Insurance as further disclosed below. The Company entered into a credit derivative that will require the Company to make certain payments in the event of deterioration in the value of the surplus notes issued by a subsidiary of Prudential Insurance. The notional amount of this credit derivative was $500 million and was reported at fair value as of March 31, 2017 and December 31, 2016 as a liability of $7 million and $17 million , respectively, and has a maturity date of December 14, 2047. No collateral was pledged in either period. In addition to writing credit protection, the Company has purchased credit protection using credit derivatives in order to hedge specific credit exposures in the Company’s investment portfolio. As of March 31, 2017 and December 31, 2016 , the Company had $223 million and $256 million of outstanding notional amounts reported at fair value as a liability of $8 million for both periods. Counterparty Credit Risk The Company is exposed to credit-related losses in the event of non-performance by counterparties to financial derivative transactions. The Company manages credit risk by entering into derivative transactions with highly rated major international financial institutions and other creditworthy counterparties, and by obtaining collateral, such as cash and securities, when appropriate. Additionally, limits are set on single party credit exposures which are subject to periodic management review. The credit exposure of the Company’s OTC derivative transactions is represented by the contracts with a positive fair value at the reporting date. To reduce credit exposures, the Company seeks to: enter into OTC derivative transactions pursuant to master agreements that provide for a netting of payments and receipts with a single counterparty, and enter into agreements that allow the use of credit support annexes, some of which are bilateral rating-sensitive agreements that require collateral postings at established threshold levels. Cleared derivatives are transactions between the Company and a counterparty where the transactions are cleared through a clearinghouse, such that each derivative counterparty is only exposed to the default of the clearinghouse. These cleared transactions require initial and daily variation margin collateral postings and include certain interest rate swaps and credit default swaps entered into on, or after, June 10, 2013, related to guidelines under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”). The Company also enters into exchange-traded futures and certain options transactions through regulated exchanges and these transactions are settled on a daily basis, thereby reducing credit risk exposure in the event of non-performance by counterparties to such financial instruments. Under fair value measurements, the Company incorporates the market’s perception of its own and the counterparty’s NPR in determining the fair value of the portion of its OTC derivative assets and liabilities that are uncollateralized. Credit spreads are applied to the derivative fair values on a net basis by counterparty. To reflect the Company’s own credit spread, a proxy based on relevant debt spreads is applied to OTC derivative net liability positions. Similarly, the Company’s counterparty’s credit spread is applied to OTC derivative net asset positions. A majority of the Company’s derivative agreements have zero thresholds which require full collateralization by the party in a liability position. The Company also has derivative agreements with non-zero thresholds; if the Company’s credit rating were to fall below a certain level, the counterparties to the derivative instruments in a net liability position may request full collateralization. In addition, certain of the Company’s derivative agreements with counterparties contain credit-risk related contingent features; if the Company’s credit rating were to fall below a certain level, the counterparties to the derivative instruments could request termination at the then fair value of the derivative resulting in settlement. As of March 31, 2017 , there were no net liability derivative positions with non-zero thresholds and/or downgrading of credit ratings; as such all derivatives have been appropriately collateralized by the Company or the counterparty in accordance with the terms of the derivative agreements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Guarantees, Contingent Liabilities and Litigation and Regulatory Matters	COMMITMENTS AND GUARANTEES, CONTINGENT LIABILITIES AND LITIGATION AND REGULATORY MATTERS Commitments and Guarantees Commercial Mortgage Loan Commitments March 31, December 31, (in millions) Total outstanding mortgage loan commitments $ 2,240 $ 1,984 Portion of commitment where prearrangement to sell to investor exists $ 438 $ 454 In connection with the Company’s commercial mortgage operations, it originates commercial mortgage loans. Commitments for loans that will be held for sale are recognized as derivatives and recorded at fair value. In certain of these transactions, the Company pre-arranges that it will sell the loan to an investor, including to government sponsored entities as discussed below, after the Company funds the loan. Commitments to Purchase Investments (excluding Commercial Mortgage Loans) March 31, December 31, (in millions) Expected to be funded from the general account and other operations outside the separate accounts $ 5,433 $ 6,002 Expected to be funded from separate accounts $ 594 $ 374 The Company has other commitments to purchase or fund investments, some of which are contingent upon events or circumstances not under the Company’s control, including those at the discretion of the Company’s counterparties. The Company anticipates a portion of these commitments will ultimately be funded from its separate accounts. Indemnification of Securities Lending Transactions March 31, December 31, (in millions) Indemnification provided to certain securities lending clients $ 5,816 $ 5,352 Fair value of related collateral associated with above indemnifications $ 5,943 $ 5,465 Accrued liability associated with guarantee $ 0 $ 0 In the normal course of business, the Company may facilitate securities lending transactions on behalf of certain client accounts (collectively, “the accounts”) for which the Company is also the investment advisor and/or the asset manager. In certain of these arrangements, the Company has provided an indemnification to the accounts to hold them harmless against losses caused by counterparty (i.e., borrower) defaults associated with the securities lending activity facilitated by the Company. Collateral is provided by the counterparty to the accounts at the inception of the loan equal to or greater than 102% of the fair value of the loaned securities and the collateral is maintained daily at 102% or greater of the fair value of the loaned securities. The Company is only at risk if the counterparty to the securities lending transaction defaults and the value of the collateral held is less than the value of the securities loaned to such counterparty. The Company believes the possibility of any payments under these indemnities is remote. Credit Derivatives Written As discussed further in Note 14, the Company writes credit derivatives under which the Company is obligated to pay the counterparty the referenced amount of the contract and receive in return the defaulted security or similar security. Guarantees of Asset Values March 31, December 31, (in millions) Guaranteed value of third parties’ assets $ 77,535 $ 77,197 Fair value of collateral supporting these assets $ 78,181 $ 77,760 Asset associated with guarantee, carried at fair value $ 5 $ 5 Certain contracts underwritten by the Retirement segment include guarantees related to financial assets owned by the guaranteed party. These contracts are accounted for as derivatives and carried at fair value. The collateral supporting these guarantees is not reflected on the Unaudited Interim Consolidated Statements of Financial Position. Indemnification of Serviced Mortgage Loans March 31, December 31, (in millions) Maximum exposure under indemnification agreements for mortgage loans serviced by the Company $ 1,414 $ 1,371 First-loss exposure portion of above $ 428 $ 416 Accrued liability associated with guarantees $ 14 $ 13 As part of the commercial mortgage activities of the Company’s Asset Management segment, the Company provides commercial mortgage origination, underwriting and servicing for certain government sponsored entities, such as Fannie Mae and Freddie Mac. The Company has agreed to indemnify the government sponsored entities for a portion of the credit risk associated with certain of the mortgages it services through a delegated authority arrangement. Under these arrangements, the Company originates multi-family mortgages for sale to the government sponsored entities based on underwriting standards they specify, and makes payments to them for a specified percentage share of losses they incur on certain loans serviced by the Company. The Company’s percentage share of losses incurred generally varies from 2% to 20% of the loan balance, and is typically based on a first-loss exposure for a stated percentage of the loan balance, plus a shared exposure with the government sponsored entity for any losses in excess of the stated first-loss percentage, subject to a contractually specified maximum percentage. The Company determines the liability related to this exposure using historical loss experience, and the size and remaining life of the asset. The Company services $11,643 million and $11,445 million of mortgages subject to these loss-sharing arrangements as of March 31, 2017 and December 31, 2016 , respectively, all of which are collateralized by first priority liens on the underlying multi-family residential properties. As of March 31, 2017 , these mortgages had a weighted-average debt service coverage ratio of 1.86 times and a weighted-average loan-to-value ratio of 59% . As of December 31, 2016 , these mortgages had a weighted-average debt service coverage ratio of 1.82 times and a weighted-average loan-to-value ratio of 59% . The Company had no losses related to indemnifications that were settled for the three months ended March 31, 2017 and 2016 , respectively. Other Guarantees March 31, December 31, (in millions) Other guarantees where amount can be determined $ 38 $ 58 Accrued liability for other guarantees and indemnifications $ 3 $ 3 The Company is also subject to other financial guarantees and indemnity arrangements. The Company has provided indemnities and guarantees related to acquisitions, dispositions, investments and other transactions that are triggered by, among other things, breaches of representations, warranties or covenants provided by the Company. These obligations are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential obligation is subject to contractual limitations, while in other cases such limitations are not specified or applicable. Included above are $31 million and $51 million as of March 31, 2017 and December 31, 2016 , respectively, of yield maintenance guarantees related to certain investments the Company sold. The Company does not expect to make any payments on these guarantees and is not carrying any liabilities associated with these guarantees. Since certain of these obligations are not subject to limitations, it is not possible to determine the maximum potential amount due under these guarantees. The accrued liabilities identified above do not include retained liabilities associated with sold businesses. Contingent Liabilities On an ongoing basis, the Company’s internal supervisory and control functions review the quality of sales, marketing and other customer interface procedures and practices and may recommend modifications or enhancements. From time to time, this review process results in the discovery of product administration, servicing or other errors, including errors relating to the timing or amount of payments or contract values due to customers or other parties. In certain cases, if appropriate, the Company may offer customers or other parties remediation and may incur charges, including the cost of such remediation, administrative costs and regulatory fines. The Company is subject to the laws and regulations of states and other jurisdictions concerning the identification, reporting and escheatment of unclaimed or abandoned funds, and is subject to audit and examination for compliance with these requirements. For additional discussion of these matters, see “ — Litigation and Regulatory Matters” below. It is possible that the results of operations or the cash flow of the Company in a particular quarterly or annual period could be materially affected as a result of payments in connection with the matters discussed above or other matters depending, in part, upon the results of operations or cash flow for such period. Management believes, however, that ultimate payments in connection with these matters, after consideration of applicable reserves and rights to indemnification, should not have a material adverse effect on the Company’s financial position. Litigation and Regulatory Matters The Company is subject to legal and regulatory actions in the ordinary course of its businesses. Pending legal and regulatory actions include proceedings relating to aspects of the Company’s businesses and operations that are specific to it and proceedings that are typical of the businesses in which it operates, including in both cases businesses that have been either divested or placed in wind-down status. Some of these proceedings have been brought on behalf of various alleged classes of complainants. In certain of these matters, the plaintiffs are seeking large and/or indeterminate amounts, including punitive or exemplary damages. The outcome of litigation or a regulatory matter, and the amount or range of potential loss at any particular time, is often inherently uncertain. The Company establishes accruals for litigation and regulatory matters when it is probable that a loss has been incurred and the amount of that loss can be reasonably estimated. For litigation and regulatory matters where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if material, is disclosed, including matters discussed below. The Company estimates that as of March 31, 2017 , the aggregate range of reasonably possible losses in excess of accruals established for those litigation and regulatory matters for which such an estimate currently can be made is less than $250 million . Any estimate is not an indication of expected loss, if any, or the Company’s maximum possible loss exposure on such matters. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly and annual basis and updates its accruals, disclosures and estimates of reasonably possible loss based on such reviews. The following discussion of litigation and regulatory matters provides an update of those matters discussed in Note 23 to the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 , and should be read in conjunction with the complete descriptions provided in the Form 10-K. Wells Fargo MyTerm Sales Alex Perea, individually and on behalf of all others similarly situated v. The Prudential Insurance Company of America, et al. In February 2017, the Amended Complaint was withdrawn with prejudice. Huffman v. The Prudential Insurance Company of America In February 2017, all parties filed motions for summary judgment. Rosen v. PRIAC, et al. In March 2017, Plaintiff filed a voluntary notice of dismissal with prejudice as to Ferguson Enterprises, Inc. and Capital Partners, LLC d/b/a Captrust Financial Advisors. Residential Mortgage-Backed Securities Trustee Litigation PICA et al. v. Citibank N.A. —In April 2017, Citibank filed a motion for summary judgment in the federal court action. PICA et al. v. Deutsche Bank, et al. —In February 2017, the Court issued a decision regarding Defendants’ motion to dismiss the amended complaint: (i) sustaining Plaintiffs’ breach of contract claims concerning the failure to remedy known servicing violations as to all sixty-two trusts at issue; (ii) sustaining Plaintiffs’ breach of contract claims concerning the failure to enforce seller representation and warranty claims as to forty-one trusts, and dismissing such claims as to the remaining twenty-one trusts; (iii) dismissing Plaintiffs’ claim for breach of fiduciary duty; and (iv) dismissing Plaintiffs’ claim for breach of duty to avoid conflicts of interest. PICA et al. v. HSBC, et al. —In January 2017, Plaintiffs filed a motion seeking class certification and appointing class representatives and class counsel. PICA et al. v. Wells Fargo Bank, et al .—In March 2017, the federal court issued an order concerning Defendant’s motion to dismiss as to the Indenture trusts: (i) sustaining plaintiffs’ breach of contract claims; plaintiffs’ claims for violations of the Trust Indenture Act of 1939; and plaintiffs’ claims for breach of the duty to avoid conflicts of interest; and (ii) dismissing plaintiffs’ claims for breach of fiduciary duty as duplicative of the sustained contract claims. Prudential Investment Portfolios 2, f/k/a Dryden Core Investment Fund, o/b/o Prudential Core Short-Term Bond Fund and Prudential Core Taxable Money Market Fund v. Bank of America Corporation, et al. In February 2017, the Court issued an order holding that antitrust claims cannot be asserted against entities affiliated with a bank that participated in the setting of LIBOR, if they were not involved in the setting of LIBOR. Combined with the Court’s December 2016 ruling, the Funds’ New Jersey antitrust claims were dismissed for lack of personal jurisdiction, while their antitrust claims continue in the New York and North Carolina actions. Summary The Company’s litigation and regulatory matters are subject to many uncertainties, and given their complexity and scope, their outcome cannot be predicted. It is possible that the Company’s results of operations or cash flow in a particular quarterly or annual period could be materially affected by an ultimate unfavorable resolution of pending litigation and regulatory matters depending, in part, upon the results of operations or cash flow for such period. In light of the unpredictability of the Company’s litigation and regulatory matters, it is also possible that in certain cases an ultimate unfavorable resolution of one or more pending litigation or regulatory matters could have a material adverse effect on the Company’s financial position. Management believes, however, that, based on information currently known to it, the ultimate outcome of all pending litigation and regulatory matters, after consideration of applicable reserves and rights to indemnification, is not likely to have a material adverse effect on the Company’s financial position.

Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BUSINESS AND BASIS OF PRESENTATION Prudential Financial, Inc. (“Prudential Financial”) and its subsidiaries (collectively, “Prudential” or the “Company” or “PFI”) provide a wide range of insurance, investment management, and other financial products and services to both individual and institutional customers throughout the United States and in many other countries. Principal products and services provided include life insurance, annuities, retirement-related services, mutual funds and investment management. The Company’s principal operations are comprised of four divisions: the U.S. Retirement Solutions and Investment Management division, the U.S. Individual Life and Group Insurance division, the International Insurance division and the Closed Block division. The Closed Block division is accounted for as a divested business that is reported separately from the divested businesses that are included in the Company’s Corporate and Other operations. The Company’s Corporate and Other operations include corporate items and initiatives that are not allocated to business segments and businesses that have been or will be divested, excluding the Closed Block division. 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. The Unaudited Interim Consolidated Financial Statements include the accounts of Prudential Financial, entities over which the Company exercises control, including majority-owned subsidiaries and variable interest entities (“VIEs”) in which the Company is considered the primary beneficiary. See Note 5 for more information on the Company’s consolidated variable interest entities. 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, 2016 . The Company’s Gibraltar Life Insurance Company, Ltd. (“Gibraltar Life”) consolidated operations use a November 30 fiscal year end for purposes of inclusion in the Company’s Consolidated Financial Statements. The Company’s unaudited interim consolidated balance sheet data as of March 31, 2017 , include the assets and liabilities of Gibraltar Life as of February 28, 2017. The Company’s unaudited interim consolidated income statement data include Gibraltar Life’s results of operations for the three months ended February 28, 2017 and February 29, 2016, respectively. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs (“DAC”) and related amortization; value of business acquired (“VOBA”) and its amortization; amortization of deferred sales inducements (“DSI”); measurement of goodwill and any related impairment; valuation of investments including derivatives and the recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; pension and other postretirement benefits; provision for income taxes and valuation of deferred tax assets; and accruals for contingent liabilities, including estimates for losses in connection with unresolved legal and regulatory matters. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Adoption of New Accounting Pronouncements	ASU adopted during the three months ended March 31, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-09 , Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payments Accounting This ASU simplifies and improves employee share-based payment accounting. The areas updated include income tax consequences, a policy election related to forfeitures, classification of awards as either equity or liability, and classification of operating and financing activity on the statement of cash flows. January 1, 2017 using various transition methods as prescribed by the ASU. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
Future Adoption Of New Accounting Pronouncements	ASU issued but not yet adopted as of March 31, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2014-09 , Revenue from Contracts with Customers (Topic 606) The ASU is based on the core principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, and assets recognized from the costs to obtain or fulfill a contract with a customer. Revenue recognition for insurance contracts and financial instruments are explicitly scoped out of the standard. January 1, 2018 using one of two retrospective application methods (early adoption permitted beginning January 1, 2017). The Company plans to adopt the standard on January 1, 2018 using the modified retrospective application. Given that insurance contracts and financial instruments are explicitly scoped out of the standard, the Company’s assessment has focused on the Asset Management segment. Based on the assessment completed to date, the Company does not expect the adoption of the ASU to have a significant impact on the Asset Management segment’s results of operations. ASU 2016-01 , Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities The ASU revises an entity’s accounting related to the recognition and measurement of certain equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. The standard also amends certain disclosure requirements associated with the fair value of financial instruments. January 1, 2018 using the modified retrospective method. The amendments are to be applied prospectively as they relate to equity investments without readily determinable fair value. The Company’s equity investments, except for those accounted for using the equity method, will generally be carried on the Consolidated Statements of Financial Position at fair value with changes in fair value reported in current earnings. The Company is continuing to assess additional impacts of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-02 , Leases (Topic 842) This ASU ensures that assets and liabilities from all outstanding lease contracts are recognized on the balance sheet (with limited exception). The ASU substantially changes a Lessee’s accounting for leases and requires the recording on balance sheet of a “right-of-use” asset and liability to make lease payments for most leases. A Lessee will continue to recognize expense in its income statement in a manner similar to the requirements under the current lease accounting standard. For Lessors, the standard modifies classification criteria and accounting for sales-type and direct financing leases and requires a Lessor to derecognize the carrying value of the leased asset that is considered to have been transferred to a Lessee and record a lease receivable and residual asset (“receivable and residual” approach). The standard also eliminates the real estate specific provisions of the current standard (i.e., sale-leaseback). January 1, 2019 using the modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-13 , Financial Instruments-Credit Losses (Topic326): Measurement of Credit Losses on Financial Instruments This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current OTTI standard for available-for-sale debt securities to require the use of an allowance rather than a direct write down of the investment, and replaces existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method, however prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an OTTI was recognized prior to the date of adoption. Early adoption is permitted beginning January 1, 2019. The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-15 , Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force) This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows. January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-18 , Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued this ASU to address diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities in the Statement of Cash Flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. January 1, 2018 using the retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2017-01 , Business Combinations (Topic 805): Clarifying the Definition of a Business In January 2017, the FASB issued this ASU to provide a more robust framework to use in determining when a set of assets and activities (“set”) is a business and to address stakeholder feedback that the definition of a business in current GAAP is applied too broadly. The primary amendments in the ASU provide a screen to exclude transactions where substantially all the fair value of the transferred set is concentrated in a single asset, or group of similar assets, from being evaluated as a business. January 1, 2018 using the prospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. It is expected that our general account real estate acquisitions will no longer be accounted for as business combinations. ASU 2017-05 , Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets In February 2017, the FASB issued this ASU to clarify the scope and application of ASC 610-20 which provides guidance on accounting for the derecognition of a nonfinancial asset or an in substance nonfinancial asset that is not a business. The ASU defines an in substance nonfinancial asset and requires the application of certain recognition and measurement principles in the new revenue recognition standard when an entity derecognizes nonfinancial assets and in substance nonfinancial assets, and the counterparty is not a customer. January 1, 2018 using the full or modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2017-08 , Receivables -Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. January 1, 2019 using the modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

See below for additional information related to internally-developed valuation for significant items in the above table. (2) Represents unadjusted prices from independent pricing services and independent indicative broker quotes where pricing inputs are not readily available. (3) Includes assets classified as fixed maturities available-for-sale, trading account assets supporting insurance liabilities and other trading account assets. (4) Includes credit-tranched securities collateralized by sub-prime mortgages, auto loans, credit cards, education loans and other asset types.
Fair Value Inputs, Assets, Quantitative Information	The tables below present quantitative information on significant internally-priced Level 3 assets and liabilities (see narrative below for quantitative information for separate account assets). As of March 31, 2017 Fair Value Valuation Techniques Unobservable Inputs Minimum Maximum Weighted Average Impact of Increase in Input on Fair Value(1) (in millions) Assets: Corporate securities(2) $ 1,916 Discounted cash flow Discount rate 0.66% - 20% 5.96% Decrease Liquidation Liquidation value 15.93% - 16.10% 16.02% Increase Liabilities: Future policy benefits(4) $ 7,640 Discounted cash flow Lapse rate(5) 0% - 13% Decrease NPR spread(6) 0.19% - 1.42% Decrease Utilization rate(7) 52% - 96% Increase Withdrawal rate See table footnote (8) below.

Mortality rate(9) 0% - 14% Decrease Equity volatility curve 16% - 25% Increase __________ (1) Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table. (2) Includes assets classified as fixed maturities available-for-sale, trading account assets supporting insurance liabilities and other trading account assets. (3) Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments. (4) Future policy benefits primarily represent general account liabilities for the living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (5) Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. (6) To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of individual living benefit contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. (7) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (8) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of March 31, 2017 and December 31, 2016 , the minimum withdrawal rate assumption is 78% and the maximum withdrawal rate assumption may be greater than 100% . The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%. (9) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0% . Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

Fair Value Measurements, Nonrecurring	The following table represents information for assets measured at fair value on a nonrecurring basis. The fair value measurement is nonrecurring as these assets are measured at fair value only when there is evidence of impairment. Assets included in the table are those that were impaired, and therefore measured at fair value, during the respective reporting periods and that are still held as of the reporting date. The estimated fair values for these amounts were determined using significant unobservable inputs (Level 3).

(2) Mortgage servicing rights are revalued based on internal models which utilize inputs. The fair value for mortgage servicing rights is determined using a discounted cash flow model incorporating assumptions for servicing revenues, adjusted for expected prepayments, delinquency rates, escrow deposit income and estimated loan servicing expenses. (3) For cost method impairments, the methodologies utilized are primarily discounted cash flow and, where appropriate, valuations provided by the general partners taking into consideration investment-related expenses.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Schedule of Derivative Instruments in Statement of Financial Position, Fair Value	The table below provides a summary of the gross notional amount and fair value of derivatives contracts by the primary underlying, excluding embedded derivatives and associated reinsurance recoverables. Many derivative instruments contain multiple underlyings. The fair value amounts below represent the gross fair value of derivative contracts prior to taking into account the netting effects of master netting agreements, cash collateral and NPR. This netting impact results in total derivative assets of $1,147 million and $1,367 million as of March 31, 2017 and December 31, 2016 , respectively, and total derivative liabilities of $203 million and $345 million as of March 31, 2017 and December 31, 2016 , respectively, reflected in the Unaudited Interim Consolidated Statements of Financial Position. Based on notional amounts, most of the Company’s derivatives do not qualify for hedge accounting as follows: i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income, ii) derivatives that are utilized as macro hedges of the Company’s exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules, and iii) synthetic GICs, which are product standalone derivatives, do not qualify as hedging instruments under hedge accounting rules.
