Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	BUSINESS AND BASIS OF PRESENTATION Prudential Financial, Inc. (“Prudential Financial”) and its subsidiaries (collectively, “Prudential” or the “Company”) 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 five divisions, which together encompass seven segments, and its Corporate and Other operations. The PGIM division is comprised of the PGIM segment, the global investment management businesses of the Company. The U.S. Workplace Solutions division consists of the Retirement and Group Insurance segments. The U.S. Individual Solutions division consists of the Individual Annuities and Individual Life segments. The Company also collectively refers to the U.S. Workplace Solutions division and the U.S. Individual Solutions division as the U.S. Financial Wellness businesses. The International Insurance division is comprised of the International Insurance segment, and the Closed Block division is comprised of the Closed Block segment. The Closed Block division is accounted for as a divested business that is reported separately from the Divested and Run-off Businesses that are included in the Company’s Corporate and Other operations. Divested and Run-off Businesses are comprised of businesses that have been, or will be, sold or exited, including businesses that have been placed in wind down status that do not qualify for “discontinued operations” accounting treatment under generally accepted accounting principles in the United States of America (“U.S. GAAP”). 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 or placed in run-off, excluding the Closed Block division. Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with 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 4 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, 2018 . Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs (“DAC”) and related amortization; value of business acquired (“VOBA”) and its amortization; amortization of deferred sales inducements (“DSI”); measurement of goodwill and any related impairment; valuation of investments including derivatives and the recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; pension and other postretirement benefits; provision for income taxes and valuation of deferred tax assets; and accruals for contingent liabilities, including estimates for losses in connection with unresolved legal and regulatory matters. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Adoption of ASU 2016-02 Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842), using the optional transition method with a cumulative-effect adjustment recorded as of the beginning of the period of adoption. This ASU substantially changes a lessee’s accounting for leases and requires the recording, on balance sheet, using a dual lease accounting model, of a “right-of-use” asset and lease liability. Leases are to be classified as either operating or finance leases. Under the standard, for operating leases, lessees recognize total lease expenses using a straight-line method and finance leases are treated as the purchase of an asset on a financing basis. 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 leveraged lease accounting model for lessors and real estate specific provisions (i.e., those related to sale-leaseback transactions); it does allow, however, a grandfathering of the leveraged lease accounting model for those existing leases that are being accounted for using such model. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the standard which eliminated the need to reassess: (a) whether any existing contracts are, or contain, leases; (b) the lease classification for any existing leases (i.e., all existing lessee arrangements that were classified as operating leases before are now classified as operating leases, and all existing lessee arrangements that were classified as capital leases before are now classified as finance leases); and (c) initial direct costs for any existing leases. The Company did not elect the practical expedient, which may be applied separately, to use hindsight in determining the lease term and in assessing impairment of the Company’s right-of-use assets. Adoption of the standard resulted in the recording of right-of-use assets and lease liabilities related to existing operating leases of approximately $600 million as of January 1, 2019. Adoption of the standard also resulted in additional required disclosures. See Note 7 for additional information. Other ASU adopted during the six months ended June 30, 2019 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters 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 which included cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The impact of the cumulative-effect adjustment to retained earnings was immaterial. ASU 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities This ASU makes targeted changes to the existing hedge accounting model to better portray the economics of an entity’s risk management activities and to simplify the use of hedge accounting. The ASU eliminates separate measurement and recording of hedge ineffectiveness. It requires entities to present the earnings effect of the hedging instrument in the same income statement line item in which the hedged item is reported and also requires expanded disclosures. January 1, 2019 using the modified retrospective method which included cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The impact of the cumulative-effect adjustment to retained earnings and accumulated other comprehensive income (loss) (“AOCI”) related to ineffectiveness of the hedge instruments outstanding at the date of adoption was immaterial. See Note 5 for additional required disclosures. ASU issued but not yet adopted as of June 30, 2019 — ASU 2018-12 ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, was issued by the FASB on August 15, 2018 and is expected to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. In July 2019, the FASB made a tentative decision to defer the effective date of this ASU to January 1, 2022 (with early adoption permitted), representing a one year extension from the original effective date of January 1, 2021. A final decision regarding the effective date is expected in the third quarter of 2019. This ASU will impact, at least to some extent, the accounting and disclosure requirements for all long-duration insurance and investment contracts issued by the Company. Outlined below are four key areas of change, although there are other less significant changes not noted below. In addition to the impacts to the balance sheet upon adoption, the Company also expects an impact to how earnings emerge thereafter. ASU 2018-12 Amended Topic Description Method of adoption Effect on the financial statements or other significant matters Cash flow assumptions used to measure the liability for future policy benefits for non-participating traditional and limited-pay insurance products Requires an entity to review, and if necessary, update the cash flow assumptions used to measure the liability for future policy benefits, for both changes in future assumptions and actual experience, at least annually using a retrospective update method with a cumulative catch-up adjustment recorded in a separate line item in the Consolidated Statements of Operations. An entity may choose one of two adoption methods for the liability for future policy benefits: (1) a modified retrospective transition method whereby the entity will apply the amendments to contracts in force as of the beginning of the earliest period presented on the basis of their existing carrying amounts, adjusted for the removal of any related amounts in AOCI or (2) a full retrospective transition method. The options for method of adoption and the impacts of such methods are under assessment. Discount rate assumption used to measure the liability for future policy benefits for non-participating traditional and limited-pay insurance products Requires discount rate assumptions to be based on an upper-medium grade fixed income instrument yield and will be required to be updated each quarter with the impact recorded through Other Comprehensive Income (“OCI”). As noted above, an entity may choose either a modified retrospective transition method or full retrospective transition method for the liability for future policy benefits. Under either method, for balance sheet remeasurement purposes, the liability for future policy benefits will be remeasured using current discount rates as of the beginning of the earliest period presented with the impact recorded as a cumulative effect adjustment to AOCI. Upon adoption, under either transition method, there will be an adjustment to AOCI as a result of remeasuring in-force contract liabilities using current upper-medium grade fixed income instrument yields. The adjustment upon adoption will largely reflect the difference between the discount rate locked-in at contract inception versus current discount rates at transition. The magnitude of such adjustment is currently being assessed. Amortization of deferred acquisition costs (DAC) and other balances Requires DAC and other balances, such as unearned revenue reserves and deferred sales inducements, to be amortized on a constant level basis over the expected term of the related contract, independent of expected profitability. An entity may apply one of two adoption methods: (1) a modified retrospective transition method whereby the entity will apply the amendments to contracts in force as of the beginning of the earliest period presented on the basis of their existing carrying amounts, adjusted for the removal of any related amounts in AOCI or (2) if an entity chooses a full retrospective transition method for its future policy benefits, as described above, it is required to also use a retrospective transition method for DAC and other balances. The options for method of adoption and the impacts of such methods are under assessment. Under the modified retrospective transition method, the Company would not expect a significant impact to the balance sheet, other than the impact of the removal of any related amounts in AOCI. Market Risk Benefits Requires an entity to measure all market risk benefits (e.g., living benefit and death benefit guarantees associated with variable annuities) at fair value with changes in value attributable to changes in an entity’s non-performance risk (“NPR”) recognized in OCI. An entity will apply a retrospective transition method which will include a cumulative-effect adjustment on the balance sheet as of the earliest period presented. Upon adoption, the Company expects an impact to retained earnings for the difference between the fair value and carrying value of benefits not currently measured at fair value (e.g., guaranteed minimum death benefits on variable annuities) and an impact from reclassifying the cumulative effect of changes in NPR from retained earnings to AOCI. The magnitude of such adjustments is currently being assessed. Other ASU issued but not yet adopted as of June 30, 2019 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-13 , Financial Instruments - Credit Losses (Topic 326): 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 the existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. 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 continuing to develop its expected credit loss models and related systems, processes and controls for assets held on the Consolidated Statement of Financial Position at amortized cost, the most significant of which are the commercial mortgage and other loans. The allowance for credit losses will likely increase when the ASU is adopted to cover expected credit losses over the lifetime of the commercial mortgage and other loans, incorporating reasonable and supportable forecasts and expected changes in future economic conditions. The extent of the impact of adoption of this ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements will depend on various factors including the economic environment and the size and type of the commercial mortgage and other loans held on the date of adoption. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test in current U.S. GAAP, which measures a goodwill impairment by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of the goodwill. Under the ASU, a goodwill impairment should be recorded for the amount by which the carrying amount of a reporting unit exceeds its fair value (capped by the total amount of goodwill allocated to the reporting unit). January 1, 2020 using the prospective method (with early adoption permitted). The Company does not plan to early adopt this ASU. The Company does not expect the adoption of the ASU to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

As of June 30, 2019 and December 31, 2018 , the gross unrealized losses on fixed maturity securities were composed of $1,096 million and $5,391 million , respectively, related to “1” highest quality or “2” high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $512 million and $1,000 million , respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of June 30, 2019 , the $1,319 million of gross unrealized losses of twelve months or more were concentrated in the Company’s corporate securities within the consumer non-cyclical, energy and utility sectors. As of December 31, 2018 , the $3,283 million of gross unrealized losses of twelve months or more were concentrated in U.S. government bonds and in the Company’s corporate securities within the utility, consumer non-cyclical and finance sectors. In accordance with its policy described in Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , the Company concluded that an adjustment to earnings for OTTI for these fixed maturity securities was not warranted at either June 30, 2019 or December 31, 2018 . These conclusions were based on a detailed analysis of the underlying credit and cash flows on each security. Gross unrealized losses are primarily attributable to general credit spread widening, increases in interest rates and foreign currency exchange rate movements. As of June 30, 2019 , the Company did not intend to sell these securities, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost basis.

Actual maturities may differ from contractual maturities, because issuers may have the right to call or prepay obligations. Asset-backed, commercial mortgage-backed and residential mortgage-backed securities are shown separately in the table above, as they do not have a single maturity date. The following table sets forth the sources of fixed maturity proceeds and related investment gains (losses), as well as losses on impairments of fixed maturities, for the periods indicated: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 (in millions) Fixed maturities, available-for-sale: Proceeds from sales(1) $ 6,659 $ 9,489 $ 16,821 $ 19,074 Proceeds from maturities/prepayments 4,704 6,553 9,192 11,779 Gross investment gains from sales and maturities 228 410 711 784 Gross investment losses from sales and maturities (95 ) (187 ) (283 ) (444 ) OTTI recognized in earnings(2) (64 ) (58 ) (99 ) (97 ) Fixed maturities, held-to-maturity: Proceeds from maturities/prepayments(3) $ 23 $ 23 $ 37 $ 59 __________ (1) Includes $332 million and $254 million of non-cash related proceeds due to the timing of trade settlements for the six months ended June 30, 2019 and 2018 , respectively. (2) Excludes the portion of OTTI amounts remaining in OCI, representing any difference between the fair value of the impaired debt security and the net present value of its projected future cash flows at the time of impairment. (3) Includes $2 million and $3 million of non-cash related proceeds due to the timing of trade settlements for the six months ended June 30, 2019 and 2018 , respectively. The following table sets forth a rollforward of pre-tax amounts remaining in OCI related to fixed maturity securities with credit loss impairments recognized in earnings, for the periods indicated: Three Months Ended Six Months Ended 2019 2018 2019 2018 (in millions) Credit loss impairments: Balance, beginning of period $ 149 $ 203 $ 140 $ 319 New credit loss impairments 4 0 20 0 Additional credit loss impairments on securities previously impaired 8 0 8 0 Increases due to the passage of time on previously recorded credit losses 2 4 3 6 Reductions for securities which matured, paid down, prepaid or were sold during the period (20 ) (42 ) (27 ) (155 ) Reductions for securities impaired to fair value during the period(1) 0 0 0 (4 ) Accretion of credit loss impairments previously recognized due to an increase in cash flows expected to be collected (1 ) (2 ) (2 ) (3 ) Balance, end of period $ 142 $ 163 $ 142 $ 163 __________ (1) Represents circumstances where the Company determined in the current period that it intends to sell the security or it is more likely than not that it will be required to sell the security before recovery of the security’s amortized cost. Assets Supporting Experience-Rated Contractholder Liabilities The following table sets forth the composition of “Assets supporting experience-rated contractholder liabilities,” as of the dates indicated: June 30, 2019 December 31, 2018 Amortized Fair Value Amortized Fair Value (in millions) Short-term investments and cash equivalents $ 371 $ 371 $ 215 $ 215 Fixed maturities: Corporate securities 13,257 13,630 13,258 13,119 Commercial mortgage-backed securities 2,239 2,297 2,346 2,324 Residential mortgage-backed securities(1) 1,002 1,014 828 811 Asset-backed securities(2) 1,595 1,626 1,649 1,665 Foreign government bonds 852 870 1,087 1,083 U.S. government authorities and agencies and obligations of U.S. states 351 402 538 577 Total fixed maturities(3) 19,296 19,839 19,706 19,579 Equity securities 1,452 1,633 1,378 1,460 Total assets supporting experience-rated contractholder liabilities(4) $ 21,119 $ 21,843 $ 21,299 $ 21,254 __________ (1) Includes publicly-traded agency pass-through securities and collateralized mortgage obligations. (2) Includes collateralized loan obligations, auto loans, education loans, credit-tranched securities collateralized by sub-prime mortgages and other asset types. Collateralized loan obligations at fair value were $1,025 million and $1,028 million as of June 30, 2019 and December 31, 2018 , respectively, all of which were rated AAA. (3) As a percentage of amortized cost, 93% of the portfolio was considered high or highest quality based on NAIC or equivalent ratings, as of both June 30, 2019 and December 31, 2018 . (4) As a percentage of amortized cost, 78% of the portfolio consisted of public securities as of both June 30, 2019 and December 31, 2018 . The net change in unrealized gains (losses) from assets supporting experience-rated contractholder liabilities still held at period end, recorded within “Other income (loss),” was $300 million and $(198) million during the three months ended June 30, 2019 and 2018 , respectively, and $769 million and $(596) million during the six months ended June 30, 2019 and 2018 , respectively.

Variable Interest Entities	VARIABLE INTEREST ENTITIES In the normal course of its activities, the Company enters into relationships with various special-purpose entities and other entities that are deemed to be variable interest entities (“VIEs”). For additional information, see Note 4 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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. 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 the Company . As of June 30, 2019 and December 31, 2018 , 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 $929 million and $836 million at June 30, 2019 and December 31, 2018 , respectively. These investments are reflected in “Fixed maturities, available-for-sale,” “Fixed maturities, trading,” “Equity securities” and “Other invested assets.” 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 limited partnerships and limited liability companies (“LPs/LLCs”), which 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 invested assets” and its maximum exposure to loss associated with these entities was $10,182 million and $9,841 million as of June 30, 2019 and December 31, 2018 , 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 3 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.

The fair value of these embedded derivatives was a net liability of $13,672 million and $8,959 million as of June 30, 2019 and December 31, 2018 , respectively, primarily included in “Future policy benefits.” (3) Recorded in “Other invested assets” and “Other liabilities” on the Unaudited Interim Consolidated Statements of Financial Position. As of June 30, 2019 , the following amounts were recorded on the Unaudited Interim Consolidated Statements of Financial Position related to the carrying amount of the hedged assets (liabilities) and cumulative basis adjustments included in the carrying amount for fair value hedges. Balance Sheet Line Item in which Hedged Item is Recorded Carrying Amount of the Hedged Assets (Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Liabilities)(1) (in millions) Fixed maturities, available-for-sale, at fair value $ 441 $ 62 Commercial mortgage and other loans $ 24 $ 2 Policyholders’ account balances $ (1,327 ) $ (85 ) Future policy benefits $ (642 ) $ (150 ) ________ (1) There are no fair value hedging adjustments for hedged assets and liabilities for which hedge accounting has been discontinued. Most of the Company’s derivatives do not qualify for hedge accounting for various reasons. For example: (i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income; (ii) derivatives that are utilized as macro hedges of the Company’s exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules; and (iii) synthetic GICs, which are product standalone derivatives, do not qualify as hedging instruments under hedge accounting rules. 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, 2018 . Fair Value, Cash Flow 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, including the offset of the hedged item in fair value hedge relationships.

(2) Presented below is a rollforward of current period cash flow hedges in AOCI before taxes: (in millions) Balance, December 31, 2018 $ 811 Cumulative-effect adjustment from the adoption of ASU 2017-12(1) 9 Amount recorded in AOCI Interest Rate 21 Currency 7 Currency/Interest Rate 341 Total amount recorded in AOCI 369 Amount reclassified from AOCI to income Interest Rate 1 Currency (2 ) Currency/Interest Rate (171 ) Total amount reclassified from AOCI to income (172 ) Balance, June 30, 2019 $ 1,017 _________ (1) See Note 2 for details. The changes in fair value of cash flow hedges are deferred in AOCI and are included in “Net unrealized investment gains (losses)” in the Unaudited Interim Consolidated Statements of Comprehensive Income; these amounts are then reclassified to earnings when the hedged item affects earnings. Using June 30, 2019 values, it is estimated that a pre-tax gain of approximately $251 million is expected to be reclassified from AOCI to earnings during the subsequent twelve months ending June 30, 2020 , offset by amounts pertaining to the hedged items. The exposures the Company is hedging with these qualifying cash flow hedges include the variability of future cash flows from forecasted transactions denominated in foreign currencies, the purchases of invested assets, and the receipt or payment of variable interest on existing financial instruments. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows for forecasted transactions is 5 years . There were no material amounts reclassified from AOCI 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. For effective net investment hedges, the amounts, before applicable taxes, recorded in the cumulative translation adjustment within AOCI were $534 million and $532 million as of June 30, 2019 and December 31, 2018 , respectively. Credit Derivatives Credit derivatives, where the Company has written credit protection on a single name reference, had outstanding notional amounts of $100 million and $ 110 million as of June 30, 2019 and December 31, 2018 , respectively. These credit derivatives are reported at fair value as an asset of $1 million as of both June 30, 2019 and December 31, 2018 . As of June 30, 2019 , the notional amount of these credit derivatives had the following NAIC ratings: $ 36 million in NAIC 1; $ 60 million in NAIC 2; and $4 million in NAIC 3. The Company has also written credit protection on certain index references with notional amounts of $2,984 million and $4,953 million as of June 30, 2019 and December 31, 2018 , respectively. These credit derivatives are reported at fair value as an asset of $100 million and $ 10 million as of June 30, 2019 and December 31, 2018 , respectively. As of June 30, 2019 , the notional amount of these credit derivatives had the following NAIC ratings: $ 51 million in NAIC 1; $1,908 million in NAIC 3; and $1,025 million NAIC 6. 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. The single name credit derivatives have maturities of less than 2 years , while the index references have maturities of less than 43 years . 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, 2019 and December 31, 2018 , the Company had $82 million and $145 million of outstanding notional amounts and reported at fair value as a liability of $0 million and $ 1 million Counterparty Credit Risk The Company is exposed to credit-related losses in the event of non-performance by counterparties to financial derivative transactions with a positive fair value. 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 agreements, as applicable; (ii) trading through central clearing and over-the-counter (“OTC”) parties; (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. Substantially all of the Company’s derivative agreements have zero thresholds which require daily full collateralization by the party in a liability position. In addition, certain of the Company’s derivative agreements contain credit-risk related contingent features; if the credit rating of one of the parties to the derivative agreement is to fall below a certain level, the party with positive fair value could request termination at the then fair value or demand immediate full collateralization from the party whose credit rating fell and is in a net liability position. As of June 30, 2019 , there were no net liability derivative positions with counterparties with credit risk-related contingent features; as such, all derivatives have been appropriately collateralized by the Company or the counterparty in accordance with the terms of the derivative agreements.

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 6 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 .

(6) Separate account assets included in the fair value hierarchy exclude investments in entities that calculate NAV 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. As of June 30, 2019 and December 31, 2018 , the fair value of such investments was $24,508 million and $25,070 million , respectively. (7) 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. (8) As of June 30, 2019 , the net embedded derivative liability position of $12.7 billion includes $0.6 billion of embedded derivatives in an asset position and $13.3 billion of embedded derivatives in a liability position. As of December 31, 2018 , the net embedded derivative liability position of $8.9 billion includes $0.7 billion of embedded derivatives in an asset position and $9.6 billion of embedded derivatives in a liability position.

(2) Includes assets classified as fixed maturities available-for-sale, assets supporting experience-rated contractholder liabilities and fixed maturities trading. (3) Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the Company has determined that market participants would use such multiples when valuing 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) Policyholders’ account balances primarily represent general account liabilities for the index-linked interest credited on certain of the Company’s life and annuity products that 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. (7) Lapse rates for contracts with living benefit guarantees 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 for contracts with index-linked crediting guarantees may be adjusted at the contract level based on the applicability of any surrender charges, product type, and market related factors such as interest rates. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. For any given contract, lapse rates vary throughout the period over which cash flows are projected for the purposes of valuing these embedded derivatives. (8) The spread over the London Inter-Bank Offered Rate (“LIBOR”) swap curve represents the premium added to the proxy for the risk-free rate (LIBOR) to reflect the Company’s estimates of rates that a market participant would use to value the living benefits in both the accumulation and payout phases and index-linked interest crediting guarantees. This spread includes an estimate of NPR, which is the risk that the obligation will not be fulfilled by the Company. NPR is primarily estimated by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. In order to reflect the financial strength ratings of the Company, credit spreads associated with funding agreements, as opposed to credit spread associated with debt, are utilized in developing this estimate because funding agreements, living benefit guarantees, and index-linked interest crediting guarantees are insurance liabilities and are therefore senior to debt. (9) 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. (10) 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, 2019 and December 31, 2018 , 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%. (11) The range reflects the mortality rates for the vast majority of business with living benefits and other contracts, with policyholders ranging from 45 to 90 years old. While the majority of living benefits have a minimum age requirement, certain other contracts do not have an age restriction. This results in contractholders with mortality rates approaching 0% for certain benefits. Mortality rates may vary by product, age, and duration. 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 6 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Changes in Level 3 Assets and Liabilities —The following tables describe 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. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter.

Leases [Abstract]
Operating Leases, Lessee	LEASES The Company occupies leased office space and other facilities in many locations under various long-term leases and has entered into numerous leases covering the long-term use of computers and other equipment. The leases, depending on their specific terms, are classified as either operating or finance with the vast majority of leases falling under the operating classification. The leases in the Company’s portfolio have remaining lease terms from less than one year to 30 years , some of which include options to extend the leases for up to 18 years , and some of which include options to terminate the leases within 8 years . An analysis of all economic and non-economic factors associated with leases containing certain options, including factors such as the existence of cancellation penalties, leasehold improvements made to the underlying assets and location of the underlying assets, is conducted to determine whether those leases are reasonably certain to renew, and, hence, should be included in the lease term that is used to establish the right-of-use assets and lease liabilities for those arrangements. The Company does not have residual guarantees associated with its lessee arrangements, nor are there any restrictions or covenants associated with its lease arrangements. Lessee Supplemental balance sheet information related to leases where the Company is the lessee is included below. Right-of-use assets and lease liabilities are included within “Other assets” and “Other liabilities” respectively.

Short-term lease costs relate to those leases with terms of twelve months or less that do not include an option to purchase the underlying asset that is reasonably certain of exercise. Lessor The Company directly owns real estate properties within its investment portfolio. Such real estate is leased to third-parties, with the Company serving as the lessor. The terms of the leases vary depending on property type (e.g., commercial or residential). In most cases, the lessee has an option to renew the lease contract based on market rates but does not have an option to purchase the property. The terms of the leases may also include provisions for the use of common areas. Such non-lease components are not separately accounted for by the Company, as a result of applying the practical expedient discussed in Note 2.

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 expense (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. The Company’s income tax provision, on a consolidated basis, amounted to an income tax expense of $394 million , or 19.5% of income (loss) before income taxes and equity in earnings of operating joint ventures, in the first six months of 2019, compared to $420 million , or 21.6% , in the first six months of 2018. The Company’s current and prior effective tax rates differed from the U.S. statutory rate of 21% primarily due to non-taxable investment income, tax credits and foreign earnings taxed at higher rates than the U.S. statutory rate. In addition, the first six months of 2018 also includes a $27 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, 2019 2018 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) $ 738 $ 200 Less: Income (loss) attributable to noncontrolling interests 30 3 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards 8 4 Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 700 405.3 $ 1.73 $ 193 419.5 $ 0.46 Effect of dilutive securities and compensation programs Add: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Basic $ 8 $ 4 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Diluted 8 4 Stock options 1.3 1.5 Deferred and long-term compensation programs 1.1 1.1 Exchangeable Surplus Notes 6 6.2 6 5.9 Diluted earnings per share Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 706 413.9 $ 1.71 $ 199 428.0 $ 0.46 Six Months Ended June 30, 2019 2018 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) $ 1,675 $ 1,564 Less: Income (loss) attributable to noncontrolling interests 35 4 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards 18 18 Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,622 407.3 $ 3.98 $ 1,542 420.8 $ 3.66 Effect of dilutive securities and compensation programs Add: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Basic $ 18 $ 18 Less: Dividends and undistributed earnings allocated to participating unvested share-based payment awards—Diluted 18 18 Stock options 1.2 1.7 Deferred and long-term compensation programs 1.1 1.1 Exchangeable Surplus Notes 11 6.2 11 5.9 Diluted earnings per share Net income (loss) attributable to Prudential Financial available to holders of Common Stock $ 1,633 415.8 $ 3.93 $ 1,553 429.5 $ 3.62 Unvested share-based payment awards that contain nonforfeitable rights to dividends are participating securities and included in the computation of earnings per share pursuant to the two-class method. Under this method, earnings attributable to Prudential Financial are allocated between Common Stock and the participating awards, as if the awards were a second class of stock. During periods of net income available to holders of Common Stock, the calculation of earnings per share excludes the income attributable to participating securities in the numerator and the dilutive impact of these securities from the denominator. In the event of a net loss available to holders of Common Stock, undistributed earnings are not allocated to participating securities and the denominator excludes the dilutive impact of these securities as they do not share in the losses of the Company. Undistributed earnings allocated to participating unvested share-based payment awards for the three months ended June 30, 2019 and 2018 , as applicable, were based on 4.5 million and 4.9 million of such awards, respectively, and for the six months ended June 30, 2019 and 2018 , as applicable, were based on 4.6 million and 4.9 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, 2019 2018 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 0.9 $ 105.95 0.8 $ 108.61 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 0.9 0.8 Six Months Ended June 30, 2019 2018 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 1.0 $ 104.57 0.5 $ 108.35 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 1.0 0.5 In September 2009, the Company issued $500 million of surplus notes with an interest rate of 5.36% per annum which were exchangeable at the option of the note holders for shares of Common Stock. As of June 30, 2019 , the exchange rate for the notes was 12.3877 shares of Common Stock per each $1,000 principal amount of surplus notes, which is equivalent to approximately 6.2 million shares and an exchange price per share of Common Stock of $80.73 . 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 the related interest expense, net of tax, is excluded from the numerator, if the overall effect is dilutive. In July 2019, the note holders delivered notice to the Company indicating their intention to exercise the exchange option. In August 2019, as a result of the note holders’ exercise of the exchange option, the Company issued approximately 6.2 million shares of Common Stock at an exchange rate equal to 12.3877 shares of Common Stock per each $1,000 principal amount of surplus notes. The Company’s obligations under the surplus notes are now satisfied.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION Segments The Company’s principal operations are comprised of five divisions, which together encompass seven segments, and its Corporate and Other operations. The PGIM division consists of the PGIM segment. The U.S. Workplace Solutions division consists of the Retirement and Group Insurance segments. The U.S. Individual Solutions division consists of the Individual Annuities and Individual Life segments. The Company also collectively refers to the U.S. Workplace Solutions division and the U.S. Individual Solutions division as the U.S. Financial Wellness businesses. 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 and Run-off Businesses that are included in Corporate and Other operations. Divested and Run-off Businesses are comprised of businesses that have been, or will be, sold or exited, including businesses that have been placed in wind down status that do not qualify for “discontinued operations” accounting treatment under U.S. GAAP. 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 or placed in run-off, excluding the Closed Black division. 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 adjustments; • charges related to realized investment gains (losses), net; • market experience updates; • net investment gains (losses) on assets supporting experience-rated contractholder liabilities and changes in experience-rated contractholder liabilities due to asset value changes; • divested and run-off businesses; 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 21 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The Company has historically recognized the immediate impacts from changes in current market conditions on estimates of profitability in current period adjusted operating income. Beginning with the second quarter of 2019, these impacts are excluded from adjusted operating income which the Company believes enhances the understanding of underlying performance trends. These amounts represent the impact of those changes on DAC and other costs and reserves, primarily resulting from variable annuity and variable and universal life products. Reconciliation of adjusted operating income to net income (loss) The table below reconciles “Adjusted operating income before income taxes” to “Income (loss) before income taxes and equity in earnings of operating joint ventures”: Three Months Ended Six Months Ended 2019 2018 2019 2018 (in millions) Adjusted operating income before income taxes by segment: PGIM $ 264 $ 254 $ 478 $ 486 Total PGIM division 264 254 478 486 Retirement 467 277 718 594 Group Insurance 81 82 134 137 Total U.S. Workplace Solutions division 548 359 852 731 Individual Annuities(1) 462 507 934 1,026 Individual Life (135 ) 43 (30 ) 79 Total U.S. Individual Solutions division 327 550 904 1,105 International Insurance 849 784 1,771 1,640 Total International Insurance division 849 784 1,771 1,640 Corporate and Other operations (335 ) (286 ) (747 ) (580 ) Total Corporate and Other (335 ) (286 ) (747 ) (580 ) Total segment adjusted operating income before income taxes 1,653 1,661 3,258 3,382 Reconciling items: Realized investment gains (losses), net, and related adjustments (548 ) 393 (1,211 ) 480 Charges related to realized investment gains (losses), net (82 ) (116 ) (57 ) (139 ) Market experience updates(2) (208 ) 0 (208 ) 0 Investment gains (losses) on assets supporting experience-rated contractholder liabilities, net 287 (193 ) 741 (596 ) Change in experience-rated contractholder liabilities due to asset value changes (313 ) 85 (716 ) 503 Divested and Run-off businesses: Closed Block division (21 ) (31 ) (40 ) (40 ) Other Divested and Run-off businesses 112 (1,526 ) 286 (1,598 ) Equity in earnings of operating joint ventures and earnings attributable to noncontrolling interests (4 ) (23 ) (37 ) (49 ) Consolidated income (loss) before income taxes and equity in earnings of operating joint ventures $ 876 $ 250 $ 2,016 $ 1,943 __________ (1) Individual Annuities segment results reflect DAC as if the individual annuity business is a stand-alone operation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES Commitments and Guarantees Commercial Mortgage Loan Commitments June 30, December 31, (in millions) Total outstanding mortgage loan commitments $ 2,293 $ 3,299 Portion of commitment where prearrangement to sell to investor exists $ 538 $ 1,490 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 $ 7,133 $ 6,941 Expected to be funded from separate accounts $ 402 $ 147 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 and Securities Repurchase Transactions June 30, December 31, (in millions) Indemnification provided to certain clients for securities lending and securities repurchase transactions(1) $ 6,520 $ 5,399 Fair value of related collateral associated with above indemnifications(1) $ 6,650 $ 5,503 Accrued liability associated with guarantee $ 0 $ 0 __________ (1) As of June 30, 2019 , indemnification provided to certain clients and fair value of related collateral associated with such indemnification include $64 million and $63 million , respectively, related to securities repurchase transactions. In the normal course of business, the Company may facilitate securities lending or securities repurchase transactions on behalf of certain client accounts (collectively, “the accounts”). 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 such transactions facilitated by the Company. In securities lending transactions, collateral is provided by the counterparty to the accounts at the inception of the transaction in an amount at least equal to 102% of the fair value of the loaned securities and the collateral is maintained daily to equal at least 102% of the fair value of the loaned securities. In securities repurchase transactions, collateral is provided by the counterparty to the accounts at the inception of the transaction in an amount at least equal to 95% of the fair value of the securities subject to repurchase and the collateral is maintained daily to equal at least 95% of the fair value of the securities subject to repurchase. The Company is only at risk if the counterparty to the transaction defaults and the value of the collateral held is less than the value of the securities loaned to, or subject to repurchase from, such counterparty. The Company believes the possibility of any payments under these indemnities is remote. Credit Derivatives Written As discussed further in Note 5, 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 $ 80,337 $ 79,215 Fair value of collateral supporting these assets $ 81,338 $ 77,897 Asset (liability) associated with guarantee, carried at fair value $ 1 $ 2 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 $ 1,980 $ 1,828 First-loss exposure portion of above $ 584 $ 543 Accrued liability associated with guarantees $ 18 $ 17 As part of the commercial mortgage activities of the Company’s PGIM 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 serviced $15,560 million and $14,335 million of mortgages subject to these loss-sharing arrangements as of June 30, 2019 and December 31, 2018 , respectively, all of which are collateralized by first priority liens on the underlying multi-family residential properties. As of June 30, 2019 , these mortgages had a weighted-average debt service coverage ratio of 1.89 times and a weighted-average loan-to-value ratio of 61% . As of December 31, 2018 , these mortgages had a weighted average debt service coverage ratio of 1.83 times and a weighted-average loan-to-value ratio of 62% . The Company had no losses related to indemnifications that were settled for both the six months ended June 30, 2019 and 2018 . Other Guarantees June 30, December 31, (in millions) Other guarantees where amount can be determined $ 55 $ 77 Accrued liability for other guarantees and indemnifications $ 0 $ 0 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 $12 million and $13 million as of June 30, 2019 and December 31, 2018 , 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 and its regulators review its operations including, but not limited to, sales and other customer interface procedures and practices, and procedures for meeting obligations to its customers and other parties. These reviews may result in the modification or enhancement of processes or the imposition of other action plans, including concerning management oversight, sales and other customer interface procedures and practices, and the timing or computation of payments to customers and 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 potentially material, is disclosed, including matters discussed below. The Company estimates that as of June 30, 2019 , the aggregate range of reasonably possible losses in excess of accruals established for those litigation and regulatory matters for which such an estimate currently can be made is less than $250 million . Any estimate is not an indication of expected loss, if any, or the Company’s maximum possible loss exposure on such matters. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly and annual basis and updates its accruals, disclosures and estimates of reasonably possible loss based on such reviews. The following discussion of litigation and regulatory matters provides an update of those matters discussed in Note 22 to the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , and should be read in conjunction with the complete descriptions provided in the Form 10-K. Individual Annuities, Individual Life and Group Insurance Huffman v. The Prudential Insurance Company of America In April 2019, the court entered a Final Judgment and Order of Dismissal.

LIBOR Litigation 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 June 2019, the court issued two orders approving stipulations dismissing with prejudice Prudential’s claims against Citigroup Inc., Citibank, N.A., Citigroup Funding Inc., and Citigroup Global Markets Inc. Regulatory Matters Securities Lending and Foreign Tax Reclaim Matter In 2016, the Company self-reported to the SEC and the U.S. Department of Labor (“DOL”), and notified other regulators, that in some cases it failed to maximize securities lending income for the benefit of certain separate account investments due to a long-standing restriction benefiting the Company that limited the availability of loanable securities. The Company has removed the restriction and implemented a remediation plan for the benefit of customers. As part of the Company’s review of this matter, in 2018 it further self-reported to the SEC, and notified other regulators, that in some cases it failed to timely process foreign tax reclaims for the separate account investments. The Company has corrected the foreign tax reclaim process and has implemented a remediation plan for the benefit of customers. The DOL’s review of the securities lending matter is closed. The Company is cooperating with the SEC in its review of the securities lending and foreign tax reclaim matters (which includes a review of the remediation plans) and has entered into discussions with the SEC staff regarding a possible settlement of both matters that would potentially involve charges under the Investment Advisers Act and financial remedies. The Company cannot predict the outcome of the discussions with the SEC regarding these matters. Summary The Company’s litigation and regulatory matters are subject to many uncertainties, and given their complexity and scope, their outcome cannot be predicted. It is possible that the Company’s results of operations or cash flow in a particular quarterly or annual period could be materially affected by an ultimate unfavorable resolution of pending litigation and regulatory matters depending, in part, upon the results of operations or cash flow for such period. In light of the unpredictability of the Company’s litigation and regulatory matters, it is also possible that in certain cases an ultimate unfavorable resolution of one or more pending litigation or regulatory matters could have a material adverse effect on the Company’s financial position. Management believes, however, that, based on information currently known to it, the ultimate outcome of all pending litigation and regulatory matters, after consideration of applicable reserves and rights to indemnification, is not likely to have a material adverse effect on the Company’s financial position.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with 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 4 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, 2018 .
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.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
Adoption of New Accounting Pronouncements	Other ASU adopted during the six months ended June 30, 2019 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters 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 which included cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The impact of the cumulative-effect adjustment to retained earnings was immaterial. ASU 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities This ASU makes targeted changes to the existing hedge accounting model to better portray the economics of an entity’s risk management activities and to simplify the use of hedge accounting. The ASU eliminates separate measurement and recording of hedge ineffectiveness. It requires entities to present the earnings effect of the hedging instrument in the same income statement line item in which the hedged item is reported and also requires expanded disclosures. January 1, 2019 using the modified retrospective method which included cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The impact of the cumulative-effect adjustment to retained earnings and accumulated other comprehensive income (loss) (“AOCI”) related to ineffectiveness of the hedge instruments outstanding at the date of adoption was immaterial. See Note 5 for additional required disclosures. Adoption of ASU 2016-02 Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842), using the optional transition method with a cumulative-effect adjustment recorded as of the beginning of the period of adoption. This ASU substantially changes a lessee’s accounting for leases and requires the recording, on balance sheet, using a dual lease accounting model, of a “right-of-use” asset and lease liability. Leases are to be classified as either operating or finance leases. Under the standard, for operating leases, lessees recognize total lease expenses using a straight-line method and finance leases are treated as the purchase of an asset on a financing basis. 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 leveraged lease accounting model for lessors and real estate specific provisions (i.e., those related to sale-leaseback transactions); it does allow, however, a grandfathering of the leveraged lease accounting model for those existing leases that are being accounted for using such model. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the standard which eliminated the need to reassess: (a) whether any existing contracts are, or contain, leases; (b) the lease classification for any existing leases (i.e., all existing lessee arrangements that were classified as operating leases before are now classified as operating leases, and all existing lessee arrangements that were classified as capital leases before are now classified as finance leases); and (c) initial direct costs for any existing leases. The Company did not elect the practical expedient, which may be applied separately, to use hindsight in determining the lease term and in assessing impairment of the Company’s right-of-use assets. Adoption of the standard resulted in the recording of right-of-use assets and lease liabilities related to existing operating leases of approximately $600 million as of January 1, 2019. Adoption of the standard also resulted in additional required disclosures. See Note 7 for additional information.
Future Adoption Of New Accounting Pronouncements	ASU issued but not yet adopted as of June 30, 2019 — ASU 2018-12 ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, was issued by the FASB on August 15, 2018 and is expected to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. In July 2019, the FASB made a tentative decision to defer the effective date of this ASU to January 1, 2022 (with early adoption permitted), representing a one year extension from the original effective date of January 1, 2021. A final decision regarding the effective date is expected in the third quarter of 2019. This ASU will impact, at least to some extent, the accounting and disclosure requirements for all long-duration insurance and investment contracts issued by the Company. Outlined below are four key areas of change, although there are other less significant changes not noted below. In addition to the impacts to the balance sheet upon adoption, the Company also expects an impact to how earnings emerge thereafter. ASU 2018-12 Amended Topic Description Method of adoption Effect on the financial statements or other significant matters Cash flow assumptions used to measure the liability for future policy benefits for non-participating traditional and limited-pay insurance products Requires an entity to review, and if necessary, update the cash flow assumptions used to measure the liability for future policy benefits, for both changes in future assumptions and actual experience, at least annually using a retrospective update method with a cumulative catch-up adjustment recorded in a separate line item in the Consolidated Statements of Operations. An entity may choose one of two adoption methods for the liability for future policy benefits: (1) a modified retrospective transition method whereby the entity will apply the amendments to contracts in force as of the beginning of the earliest period presented on the basis of their existing carrying amounts, adjusted for the removal of any related amounts in AOCI or (2) a full retrospective transition method. The options for method of adoption and the impacts of such methods are under assessment. Discount rate assumption used to measure the liability for future policy benefits for non-participating traditional and limited-pay insurance products Requires discount rate assumptions to be based on an upper-medium grade fixed income instrument yield and will be required to be updated each quarter with the impact recorded through Other Comprehensive Income (“OCI”). As noted above, an entity may choose either a modified retrospective transition method or full retrospective transition method for the liability for future policy benefits. Under either method, for balance sheet remeasurement purposes, the liability for future policy benefits will be remeasured using current discount rates as of the beginning of the earliest period presented with the impact recorded as a cumulative effect adjustment to AOCI. Upon adoption, under either transition method, there will be an adjustment to AOCI as a result of remeasuring in-force contract liabilities using current upper-medium grade fixed income instrument yields. The adjustment upon adoption will largely reflect the difference between the discount rate locked-in at contract inception versus current discount rates at transition. The magnitude of such adjustment is currently being assessed. Amortization of deferred acquisition costs (DAC) and other balances Requires DAC and other balances, such as unearned revenue reserves and deferred sales inducements, to be amortized on a constant level basis over the expected term of the related contract, independent of expected profitability. An entity may apply one of two adoption methods: (1) a modified retrospective transition method whereby the entity will apply the amendments to contracts in force as of the beginning of the earliest period presented on the basis of their existing carrying amounts, adjusted for the removal of any related amounts in AOCI or (2) if an entity chooses a full retrospective transition method for its future policy benefits, as described above, it is required to also use a retrospective transition method for DAC and other balances. The options for method of adoption and the impacts of such methods are under assessment. Under the modified retrospective transition method, the Company would not expect a significant impact to the balance sheet, other than the impact of the removal of any related amounts in AOCI. Market Risk Benefits Requires an entity to measure all market risk benefits (e.g., living benefit and death benefit guarantees associated with variable annuities) at fair value with changes in value attributable to changes in an entity’s non-performance risk (“NPR”) recognized in OCI. An entity will apply a retrospective transition method which will include a cumulative-effect adjustment on the balance sheet as of the earliest period presented. Upon adoption, the Company expects an impact to retained earnings for the difference between the fair value and carrying value of benefits not currently measured at fair value (e.g., guaranteed minimum death benefits on variable annuities) and an impact from reclassifying the cumulative effect of changes in NPR from retained earnings to AOCI. The magnitude of such adjustments is currently being assessed. Other ASU issued but not yet adopted as of June 30, 2019 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-13 , Financial Instruments - Credit Losses (Topic 326): 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 the existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. 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 continuing to develop its expected credit loss models and related systems, processes and controls for assets held on the Consolidated Statement of Financial Position at amortized cost, the most significant of which are the commercial mortgage and other loans. The allowance for credit losses will likely increase when the ASU is adopted to cover expected credit losses over the lifetime of the commercial mortgage and other loans, incorporating reasonable and supportable forecasts and expected changes in future economic conditions. The extent of the impact of adoption of this ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements will depend on various factors including the economic environment and the size and type of the commercial mortgage and other loans held on the date of adoption. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test in current U.S. GAAP, which measures a goodwill impairment by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of the goodwill. Under the ASU, a goodwill impairment should be recorded for the amount by which the carrying amount of a reporting unit exceeds its fair value (capped by the total amount of goodwill allocated to the reporting unit). January 1, 2020 using the prospective method (with early adoption permitted). The Company does not plan to early adopt this ASU. The Company does not expect the adoption of the ASU to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

Mortality rate(11) 0% - 15% Decrease Equity volatility curve 18% - 22% Increase __________ (1) Conversely, the impact of a decrease in input would have the opposite impact on fair value as that presented in the table. (2) Includes assets classified as fixed maturities available-for-sale, assets supporting experience-rated contractholder liabilities and fixed maturities trading. (3) Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the Company has determined that market participants would use such multiples when valuing 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) Policyholders’ account balances primarily represent general account liabilities for the index-linked interest credited on certain of the Company’s life and annuity products that 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. (7) Lapse rates for contracts with living benefit guarantees 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 for contracts with index-linked crediting guarantees may be adjusted at the contract level based on the applicability of any surrender charges, product type, and market related factors such as interest rates. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. For any given contract, lapse rates vary throughout the period over which cash flows are projected for the purposes of valuing these embedded derivatives. (8) The spread over the London Inter-Bank Offered Rate (“LIBOR”) swap curve represents the premium added to the proxy for the risk-free rate (LIBOR) to reflect the Company’s estimates of rates that a market participant would use to value the living benefits in both the accumulation and payout phases and index-linked interest crediting guarantees. This spread includes an estimate of NPR, which is the risk that the obligation will not be fulfilled by the Company. NPR is primarily estimated by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. In order to reflect the financial strength ratings of the Company, credit spreads associated with funding agreements, as opposed to credit spread associated with debt, are utilized in developing this estimate because funding agreements, living benefit guarantees, and index-linked interest crediting guarantees are insurance liabilities and are therefore senior to debt. (9) 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. (10) 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, 2019 and December 31, 2018 , 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%. (11) The range reflects the mortality rates for the vast majority of business with living benefits and other contracts, with policyholders ranging from 45 to 90 years old. While the majority of living benefits have a minimum age requirement, certain other contracts do not have an age restriction. This results in contractholders with mortality rates approaching 0% for certain benefits. Mortality rates may vary by product, age, and duration. 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 describe 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. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter.

Fair Value Measurements, Nonrecurring	The following tables represent 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 a triggering event (e.g., an evidence of impairment). Assets included in the table are those that were impaired 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). Three Months Ended Six Months Ended 2019 2018 2019 2018 (in millions) Realized investment gains (losses) net: Commercial mortgage loans(1) $ 0 $ (13 ) $ 0 $ (13 ) Mortgage servicing rights(2) $ (1 ) $ 2 $ (2 ) $ 4 June 30, 2019 December 31, 2018 (in millions) Carrying value after measurement as of period end: Commercial mortgage loans(1) $ 14 $ 47 Mortgage servicing rights(2) $ 66 $ 73 __________ (1) Commercial mortgage loans are valued based on discounted cash flows utilizing market rates or the fair value of the underlying real estate collateral. (2) Mortgage servicing rights are valued using a discounted cash flow model. The model incorporates assumptions for servicing revenues, which are adjusted for expected prepayments, delinquency rates, escrow deposit income and estimated loan servicing expenses. The discount rates incorporated into the model are determined based on the estimated returns a market participant would require for this business including a liquidity and risk premium. This estimate includes available relevant data from any active market sales of mortgage servicing rights.
