Business and Basis of Presentat

Business and Basis of Presentation	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	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 June 30, 2017 , include the assets and liabilities of Gibraltar Life as of May 31, 2017. The Company’s unaudited interim consolidated income statement data include Gibraltar Life’s results of operations for the three and six months ended May 31, 2017 and 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. Out of Period Adjustments During the second quarter of 2016, the Company recorded an out of period adjustment resulting in a decrease of $148 million to “Income (loss) before income taxes and equity in earnings of operating joint ventures” for the three-month period ended June 30, 2016. The adjustment reflects a charge to increase reserves, net of a related increase in DAC, for certain universal life products within the Individual Life business. Management evaluated the adjustment and concluded it was not material to the then current quarter or to any previously reported quarterly or annual financial statements. See Note 11 for additional information on the impact of this adjustment to the Company’s operating segments. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Accounting Policies [Abstract]
Significant Accounting Policies and Pronouncements	SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS Accounting for Certain Reinsurance Contracts in our Individual Life business During the second quarter of 2017, the Company recognized a charge of $237 million in the Individual Life segment, reflecting a change in estimate of reinsurance cash flows associated with universal life products as well as a change in method of reflecting these cash flows in the financial statements. Under the previous method of accounting, with the exception of recoveries pertaining to no lapse guarantees, reinsurance cash flows (e.g., premiums and recoveries) were generally recognized as they occurred. Under the new method, the expected reinsurance cash flows are recognized more ratably over the life of the underlying reinsured policies. In conjunction with this change, the way in which reinsurance is reflected in estimated gross profits used for the amortization of unearned revenue reserves, deferred policy acquisition costs and VOBA was also revised. The change represents a change in accounting estimate effected by a change in accounting principle and is included within the Company’s annual reviews and update of assumptions and other refinements. The change in accounting estimate reflected insights gained from revised cashflow modeling enabled by a systems conversion, which prompted the change to a preferable accounting method. This new methodology is viewed as preferable as the Company believes it better reflects the economics of reinsurance transactions by aligning the results of reinsurance activity more closely to the underlying direct insurance activity and by better reflecting the profit pattern of this business for purposes of the amortization of the balances noted above. 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 six months ended June 30, 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 June 30, 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 is explicitly scoped out of the standard. January 1, 2018 using the modified retrospective method. 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.

As of December 31, 2016 , the $1,420 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in the energy, utility and capital goods sectors of the Company’s corporate securities.

For additional information, see Note 5 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Consolidated Variable Interest Entities 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.

(2) Recourse is limited to the assets of the respective VIE and does not extend to the general credit of Prudential Financial . As of June 30, 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. 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 $730 million and $515 million at June 30, 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 classifies these investments as “Other long-term investments” and its maximum exposure to loss associated with these entities was $8,363 million and $8,010 million as of June 30, 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 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.

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 5.8 (5.8 ) Stock-based compensation programs(1) 0.0 (3.2 ) 3.2 Balance, June 30, 2017 660.1 233.1 427.0 __________ (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 June 30, 2017 , 5.8 million shares of the Company’s Common Stock were repurchased under this authorization at a total cost of $625 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 .

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 June 30, 2017 2016 Income Weighted Per Share Income Weighted Per Share (in millions, except per share amounts) Basic earnings per share Net income (loss) $ 496 $ 925 Less: Income (loss) attributable to noncontrolling interests 5 4 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards 6 11 Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 485 428.3 $ 1.13 $ 910 441.1 $ 2.06 Effect of dilutive securities and compensation programs Add: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Basic $ 6 $ 11 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Diluted 7 11 Stock options 2.1 1.8 Deferred and long-term compensation programs 1.0 0.8 Exchangeable Surplus Notes 5 5.8 5 5.6 Diluted earnings per share Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 489 437.2 $ 1.12 $ 915 449.3 $ 2.04 Six Months Ended June 30, 2017 2016 Income Weighted Average Shares Per Share Amount Income Weighted Average Shares Per Share Amount (in millions, except per share amounts) Basic earnings per share Net income (loss) $ 1,868 $ 2,294 Less: Income (loss) attributable to noncontrolling interests 8 37 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards 23 26 Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,837 429.1 $ 4.28 $ 2,231 443.2 $ 5.03 Effect of dilutive securities and compensation programs Add: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Basic $ 23 $ 26 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Diluted 23 25 Stock options 2.2 1.6 Deferred and long-term compensation programs 1.0 0.9 Exchangeable Surplus Notes 9 5.8 9 5.6 Diluted earnings per share Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,846 438.1 $ 4.21 $ 2,241 451.3 $ 4.97 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 and six months ended June 30, 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 June 30, 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 0.4 $ 110.26 3.7 $ 83.56 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 0.0 0.0 Antidilutive shares due to net loss available to holders of Common Stock 0.0 0.0 Total antidilutive stock options and shares 0.4 3.7 Six Months Ended June 30, 2017 2016 Shares Exercise Price Per Share Shares Exercise Price Per Share (in millions, except per share amounts, based on weighted average) Antidilutive stock options based on application of the treasury stock method 0.3 $ 110.32 3.8 $ 83.40 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 0.3 0.0 Antidilutive shares due to net loss available to holders of Common Stock 0.0 0.0 Total antidilutive stock options and shares 0.6 3.8 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.

(2) Includes Prudential Financial debt of $512 million and $535 million at June 30, 2017 and December 31, 2016 , respectively. (3) Excludes the current portion of long-term debt. 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 contingent financing facility in the form of a put option agreement. The Company also maintains syndicated, unsecured committed credit facilities as an alternative source of liquidity. At June 30, 2017 , no amounts were drawn on the credit facilities. For additional information on these alternative sources of liquidity, see Note 14 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In July 2017, the Company amended and restated its $4.0 billion five -year credit facility that has both Prudential Financial and Prudential Funding as borrowers and a syndicate of financial institutions as lenders, extending the term of the facility to July 2022 . Borrowings under the credit facility may be used for general corporate purposes, and the Company expects that it may borrow under the facility from time to time to fund its working capital needs and those of its subsidiaries. In addition, amounts under the credit facility may be drawn in the form of standby letters of credit that can be used to meet the operating needs of the Company and its subsidiaries. The credit facility contains representations and warranties, covenants and events of default that are customary for facilities of this type, and borrowings under the facility are not contingent on the borrowers’ credit ratings nor subject to material adverse change clauses. Borrowings under the facility are conditioned on the continued satisfaction of customary conditions, including the maintenance by the Company of consolidated net worth of at least $20.958 billion , which for this purpose is calculated as U.S. GAAP equity, excluding accumulated other comprehensive income (loss), equity of non-controlling interests and equity attributable to the Closed Block. Long-term Debt The table below presents the Company’s long-term debt as of the dates indicated: June 30, 2017 December 31, 2016 (in millions) Fixed-rate notes: Surplus notes $ 840 $ 840 Surplus notes subject to set-off arrangements(1) 4,503 4,403 Senior notes 9,233 9,236 Mortgage debt(2) 188 177 Floating-rate notes: Surplus notes 499 499 Surplus notes subject to set-off arrangements(1) 1,638 1,456 Senior notes(3) 515 1,063 Mortgage debt(4) 531 409 Junior subordinated notes 5,820 5,817 Subtotal 23,767 23,900 Less: assets under set-off arrangements(1) 6,141 5,859 Total long-term debt(5) $ 17,626 $ 18,041 __________ (1) The surplus notes have corresponding assets where rights to set-off exist, thereby reducing the amount of surplus notes included in long-term debt. (2) Includes $69 million and $82 million of debt denominated in foreign currency at June 30, 2017 and December 31, 2016 , respectively. (3) Includes $56 million and $55 million of debt denominated in foreign currency at June 30, 2017 and December 31, 2016 , respectively. (4) Includes $232 million and $221 million of debt denominated in foreign currency at June 30, 2017 and December 31, 2016 , respectively. (5) Includes Prudential Financial debt of $15,289 million and $15,389 million at June 30, 2017 and December 31, 2016 , respectively. At June 30, 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 June 30, 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 June 30, 2017 , the outstanding balance of the Company’s medium-term notes was $9.5 billion , a decrease of $108 million from December 31, 2016 , due to maturities. 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 June 30, 2017 , the outstanding balance of retail notes was $457 million . Mortgage Debt. As of June 30, 2017 , the Company’s subsidiaries had mortgage debt of $719 million that has recourse only to real estate property held for investment by those subsidiaries. This represents an increase of $60 million from December 31, 2016 , primarily due to new borrowings of $161 million and $12 million from foreign exchange fluctuations, partially offset by $73 million of maturities and $41 million in prepayment activity.

Retirement Benefits [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. Net periodic (benefit) cost included in “General and administrative expenses” includes the following components: Three Months Ended June 30, Pension Benefits Other Postretirement Benefits 2017 2016 2017 2016 (in millions) Components of net periodic (benefit) cost Service cost $ 71 $ 63 $ 5 $ 4 Interest cost 119 124 21 23 Expected return on plan assets (195 ) (188 ) (26 ) (27 ) Amortization of prior service cost (1 ) (2 ) 0 0 Amortization of actuarial (gain) loss, net 48 45 9 11 Settlements 0 1 0 0 Special termination benefits 0 2 0 0 Net periodic (benefit) cost $ 42 $ 45 $ 9 $ 11 Six Months Ended June 30, Pension Benefits Other Postretirement Benefits 2017 2016 2017 2016 (in millions) Components of net periodic (benefit) cost Service cost $ 142 $ 125 $ 10 $ 9 Interest cost 238 249 41 46 Expected return on plan assets (390 ) (377 ) (51 ) (53 ) Amortization of prior service cost (2 ) (3 ) 0 (1 ) Amortization of actuarial (gain) loss, net 96 90 18 21 Settlements 0 2 0 0 Special termination benefits 3 2 0 0 Net periodic (benefit) cost $ 87 $ 88 $ 18 $ 22 During the six months ended June 30, 2017, the Company made cash contributions of $105 million to its pension plans and anticipates making an additional $75 million of cash contributions during the remainder of 2017.

Segment Information

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: • 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. The Company, however, 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. For more information on these reconciling items, see Note 22 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In addition, as discussed in Note 1, the Company recorded an out of period adjustment resulting in a decrease of $148 million to “Income (loss) before income taxes and equity in earnings of operating joint ventures” for the three-month period ended June 30, 2016. The adjustment resulted in a decrease in adjusted operating income before income taxes of $148 million for the Individual Life segment in that period.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company uses a full year projected effective tax rate approach to calculate year-to-date taxes. 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.” The interim period tax (or benefit) is the difference between the year-to-date income tax provision and the amounts reported for the previous interim periods of the fiscal year. Our income tax provision, on a consolidated basis, amounted to an income tax expense of $520 million , or 22.1% of income (loss) before income taxes and equity in earnings of operating joint ventures, in the first six months of 2017, compared to $799 million , or 26.0% of income (loss) before income taxes and equity in earnings of operating joint ventures in the first six months 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 six months of 2017 also includes a $31 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 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. 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. 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. For a discussion of Company’s valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 20 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

(2) Excludes notes with fair value of $1,738 million and $1,456 million as of June 30, 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) 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 measured at net asset value (“NAV”) per share (or its equivalent) as a practical expedient. At June 30, 2017 and December 31, 2016 , the fair values of such investments were $1,857 million and $1,579 million respectively. (7) Separate account assets included in the fair value hierarchy, excludes investments in entities that calculate net asset value per share (or its equivalent) as a practical expedient. Such investments excluded from the fair value hierarchy, include investments in real estate, hedge funds and other invested assets, for which fair value is measured at net asset value per share (or its equivalent). At June 30, 2017 and December 31, 2016 , the fair value of such investments was $25,669 million and $25,619 million , respectively. (8) 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. (9) As of June 30, 2017 , the net embedded derivative liability position of $10.0 billion includes $0.6 billion of embedded derivatives in an asset position and $10.6 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. 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. The following table presents the transfers between Level 1 and Level 2 for dates indicated below: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (in millions) Transferred from Level 1 to Level 2 $ 17 $ 26 $ 63 $ 66 Transferred from Level 2 to Level 1 $ 27 $ 14 $ 83 $ 31 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.

Mortality rate(10) 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) Changes in the fair value of separate account assets are borne by customers and thus are offset by changes in separate account liabilities on the Company’s Unaudited Interim Consolidated Statements of Financial Position. As a result, changes in value associated with these investments are not reflected in the Company’s Unaudited Interim Consolidated Statements of Operations. (5) 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. (6) 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. (7) To reflect non-performance risk (“NPR”), the Company incorporates an additional spread over the London Inter-Bank Offered Rate (“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. (8) 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. (9) 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 June 30, 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%. (10) 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. Interrelationships Between Unobservable Inputs — In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another or multiple inputs. For the discussion of the relationships between unobservable inputs as well as market factors that may affect the range of inputs used in the valuation of Level 3 assets and liabilities, see Note 20 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Changes in Level 3 Assets and Liabilities —The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate. For further information on valuation processes, see Note 20 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS Types of Derivative Instruments and Derivative Strategies The Company utilizes various derivatives instruments and strategies to manage its risk. Commonly used derivative instrument include, but are not necessarily limited to: • Interest rate contracts: swaps, options, swaptions, caps and floors • Equity contracts: options and total return swaps • Foreign exchange contracts: futures, options, forwards and swaps • Credit contracts: single and index reference credit default swaps • Other contracts: to-be-announced forward contracts, loan commitments, embedded derivatives and synthetic guaranteed investment contracts For detailed information on these contracts and the related strategies, see Note 21 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . 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 $1,950 million and $1,367 million as of June 30, 2017 and December 31, 2016 , respectively, and total derivative liabilities of $645 million and $345 million as of June 30, 2017 and December 31, 2016 , respectively, reflected in the Unaudited Interim Consolidated Statements of Financial Position. Primary Underlying/Instrument Type June 30, 2017 December 31, 2016 Gross Fair Value Gross Fair Value Notional Assets Liabilities Notional Assets Liabilities (in millions) Derivatives Designated as Hedge Accounting Instruments: Interest Rate Interest Rate Swaps $ 1,008 $ 16 $ (99 ) $ 1,117 $ 17 $ (111 ) Foreign Currency Foreign Currency Forwards 165 1 (2 ) 167 3 (1 ) Currency/Interest Rate Foreign Currency Swaps 17,295 1,379 (302 ) 14,737 1,956 (54 ) Total Qualifying Hedges $ 18,468 $ 1,396 $ (403 ) $ 16,021 $ 1,976 $ (166 ) Derivatives Not Qualifying as Hedge Accounting Instruments: Interest Rate Interest Rate Swaps $ 170,715 $ 9,156 $ (4,170 ) $ 162,131 $ 8,969 $ (4,274 ) Interest Rate Futures 27,406 2 (36 ) 31,183 55 (1 ) Interest Rate Options 15,176 183 (154 ) 13,290 289 (132 ) Interest Rate Forwards 549 0 (3 ) 321 0 (1 ) Foreign Currency Foreign Currency Forwards 21,954 185 (491 ) 21,042 372 (892 ) Foreign Currency Options 83 0 0 93 0 0 Currency/Interest Rate Foreign Currency Swaps 13,314 1,006 (343 ) 12,336 1,218 (311 ) Credit Credit Default Swaps 845 2 (9 ) 918 1 (25 ) Equity Equity Futures 338 1 0 1,371 0 (5 ) Equity Options 13,933 130 (91 ) 12,020 102 (93 ) Total Return Swaps 15,260 63 (240 ) 18,167 101 (390 ) Commodity Commodity Futures 0 0 0 1 0 0 Synthetic GICs 76,999 4 0 77,197 5 0 Total Non-Qualifying Derivatives $ 356,572 $ 10,732 $ (5,537 ) $ 350,070 $ 11,112 $ (6,124 ) Total Derivatives(1) $ 375,040 $ 12,128 $ (5,940 ) $ 366,091 $ 13,088 $ (6,290 ) __________ (1) Excludes embedded derivatives and associated reinsurance recoverables which contain multiple underlyings. The fair value of these embedded derivatives was a net liability of $10,015 million and $8,252 million as of June 30, 2017 and December 31, 2016 , respectively, primarily included in “Future policy benefits.” 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 guaranteed investment contracts (“GICs”), which are product standalone derivatives, do not qualify as hedging instruments under hedge accounting rules. Offsetting Assets and Liabilities The following table presents recognized derivative instruments (excluding embedded derivatives and associated reinsurance recoverables), and repurchase and reverse repurchase agreements that are offset in the Unaudited Interim Consolidated Statements of Financial Position, and/or are subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in the Unaudited Interim Consolidated Statements of Financial Position.

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 six months ended June 30, 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 June 30, 2017 (539 ) Amount reclassified into current period earnings 3 Balance, June 30, 2017 $ 780 Using June 30, 2017 values, it is estimated that a pre-tax gain of approximately $163 million will be reclassified from AOCI to earnings during the subsequent twelve months ending June 30, 2018 , offset by amounts pertaining to the hedged items. As of June 30, 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 $529 million and $536 million as of June 30, 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 $107 million and $ 112 million as of June 30, 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 June 30, 2017 and December 31, 2016 , respectively. As of June 30, 2017 , the notional amount of these credit derivatives had the following NAIC ratings: $ 36 million in NAIC 1; $ 61 million in NAIC 2; $5 million in NAIC 3; $1 million in NAIC 4; $1 million in NAIC 5; and $3 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 June 30, 2017 and December 31, 2016 . As of June 30, 2017 , the notional amount of these credit derivatives 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 June 30, 2017 and December 31, 2016 as a liability of $2 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 June 30, 2017 and December 31, 2016 , the Company had $188 million and $256 million of outstanding notional amounts reported at fair value as a liability of $6 million and $8 million , respectively. 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 (i) entering into derivative transactions with highly rated major international financial institutions and other creditworthy counterparties governed by master netting agreement as applicable, (ii) trading through a central clearinghouse and over-the-counter (“OTC”), (iii) obtaining collateral, such as cash and securities, when appropriate, and (iv) setting limits on single party credit exposures which are subject to periodic management review. For detailed information on counterparty credit risk, see Counterparty Credit Risk in Note 21 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . 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 June 30, 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 June 30, December 31, (in millions) Total outstanding mortgage loan commitments $ 2,081 $ 1,984 Portion of commitment where prearrangement to sell to investor exists $ 486 $ 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) June 30, December 31, (in millions) Expected to be funded from the general account and other operations outside the separate accounts(1) $ 7,628 $ 7,232 Expected to be funded from separate accounts(1) $ 140 $ 470 __________ (1) The amounts at December 31, 2016 have been revised to correct the previously reported amounts. 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 June 30, December 31, (in millions) Indemnification provided to certain securities lending clients $ 4,707 $ 5,352 Fair value of related collateral associated with above indemnifications $ 4,817 $ 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 June 30, December 31, (in millions) Guaranteed value of third parties’ assets $ 76,999 $ 77,197 Fair value of collateral supporting these assets $ 77,956 $ 77,760 Asset associated with guarantee, carried at fair value $ 4 $ 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 June 30, December 31, (in millions) Maximum exposure under indemnification agreements for mortgage loans serviced by the Company $ 1,439 $ 1,371 First-loss exposure portion of above $ 435 $ 416 Accrued liability associated with guarantees $ 13 $ 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 $11,718 million and $11,445 million of mortgages subject to these loss-sharing arrangements as of June 30, 2017 and December 31, 2016 , respectively, all of which are collateralized by first priority liens on the underlying multi-family residential properties. As of June 30, 2017 , these mortgages had a weighted-average debt service coverage ratio of 1.94 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 six months ended June 30, 2017 and 2016 , respectively. Other Guarantees June 30, December 31, (in millions) Other guarantees where amount can be determined $ 38 $ 58 Accrued liability for other guarantees and indemnifications $ 4 $ 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 June 30, 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 June 30, 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. Prudential of Brazil Labor and Employment Matters Prudential of Brazil (“POB”) sells insurance products to consumers through life planner franchisees (“Life Planners”), who are engaged as independent life insurance brokers and not as employees. When a Life Planner’s contractual relationship with POB is terminated, in many cases the Life Planner commences a labor suit against POB alleging entitlement to employment related benefits. POB is a defendant in numerous such lawsuits in Brazil brought by former Life Planners, and has been subject to regulatory actions challenging the validity of POB's franchise model. POB may also become subject to additional former Life Planner labor suits and regulatory actions in the future. POB has recently modified its franchise model to, among other things, mitigate the labor risk involving Life Planners. 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. Bouder v. PFI In August 2017, the Court issued an order granting preliminary approval of the parties’ class action settlement. 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. In June 2017, the state court issued a decision regarding Defendants’ motion to dismiss the amended complaint: (i) sustaining Plaintiffs’ breach of contract claims concerning Citibank’s pre-Event of Default obligations; (ii) dismissing Plaintiffs’ breach of contract claims concerning Citibank’s post-Event of Default obligations; (iii) sustaining Plaintiffs’ implied covenant of good faith and fair dealing claim; (iv) dismissing Plaintiffs’ claim for breach of fiduciary duty; and (v) dismissing Plaintiffs’ claim for breach of duty to avoid conflicts of interest. In July 2017, Citibank filed an appeal to the Appellate Division of the Supreme Court of New York, First Department, from the June 2017 decision denying, in part, its motion to dismiss. 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. In May 2017, Wells Fargo filed a third-party complaint for contribution against PGIM, Inc., alleging that, in the event the Prudential Plaintiff Funds prevail on their claims for damages against Wells Fargo, PGIM must contribute to the award due to PGIM’s alleged breach of fiduciary duties owed to the Funds in managing the Funds’ RMBS investments. In June 2017, Wells Fargo filed a motion to dismiss the complaint in New York state court. 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.

Significant Accounting Polici23

Significant Accounting Policies and Pronouncements (Policies)	6 Months Ended
	Jun. 30, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Intercompany balances and transactions have been eliminated. 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 June 30, 2017 , include the assets and liabilities of Gibraltar Life as of May 31, 2017. The Company’s unaudited interim consolidated income statement data include Gibraltar Life’s results of operations for the three and six months ended May 31, 2017 and 2016, respectively.
Use of Estimates	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.
Out of Period Adjustments	Out of Period Adjustments During the second quarter of 2016, the Company recorded an out of period adjustment resulting in a decrease of $148 million to “Income (loss) before income taxes and equity in earnings of operating joint ventures” for the three-month period ended June 30, 2016. The adjustment reflects a charge to increase reserves, net of a related increase in DAC, for certain universal life products within the Individual Life business. Management evaluated the adjustment and concluded it was not material to the then current quarter or to any previously reported quarterly or annual financial statements. See Note 11 for additional information on the impact of this adjustment to the Company’s operating segments.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
Accounting for Certain Reinsurance Contracts in our Individual Life business	Accounting for Certain Reinsurance Contracts in our Individual Life business During the second quarter of 2017, the Company recognized a charge of $237 million in the Individual Life segment, reflecting a change in estimate of reinsurance cash flows associated with universal life products as well as a change in method of reflecting these cash flows in the financial statements. Under the previous method of accounting, with the exception of recoveries pertaining to no lapse guarantees, reinsurance cash flows (e.g., premiums and recoveries) were generally recognized as they occurred. Under the new method, the expected reinsurance cash flows are recognized more ratably over the life of the underlying reinsured policies. In conjunction with this change, the way in which reinsurance is reflected in estimated gross profits used for the amortization of unearned revenue reserves, deferred policy acquisition costs and VOBA was also revised. The change represents a change in accounting estimate effected by a change in accounting principle and is included within the Company’s annual reviews and update of assumptions and other refinements. The change in accounting estimate reflected insights gained from revised cashflow modeling enabled by a systems conversion, which prompted the change to a preferable accounting method. This new methodology is viewed as preferable as the Company believes it better reflects the economics of reinsurance transactions by aligning the results of reinsurance activity more closely to the underlying direct insurance activity and by better reflecting the profit pattern of this business for purposes of the amortization of the balances noted above.
Accounting Standards Updates 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 six months ended June 30, 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 June 30, 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 is explicitly scoped out of the standard. January 1, 2018 using the modified retrospective method. 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.

(8) 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. (9) As of June 30, 2017 , the net embedded derivative liability position of $10.0 billion includes $0.6 billion of embedded derivatives in an asset position and $10.6 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.

(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) Changes in the fair value of separate account assets are borne by customers and thus are offset by changes in separate account liabilities on the Company’s Unaudited Interim Consolidated Statements of Financial Position. As a result, changes in value associated with these investments are not reflected in the Company’s Unaudited Interim Consolidated Statements of Operations. (5) 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. (6) 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. (7) To reflect non-performance risk (“NPR”), the Company incorporates an additional spread over the London Inter-Bank Offered Rate (“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. (8) 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. (9) 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 June 30, 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%. (10) 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, Assets Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.

Fair Value, Liabilities Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate. For further information on valuation processes, see Note 20 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

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. (4) Long-lived assets held for sale are valued based on internal estimate utilizing comparable sales and asset specific conditions.
