Business and Basis of Presentat

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	BUSINESS AND BASIS OF PRESENTATION Pruco Life Insurance Company (“Pruco Life”) is a wholly-owned subsidiary of The Prudential Insurance Company of America (“Prudential Insurance”), which in turn is a direct wholly-owned subsidiary of Prudential Financial, Inc. (“Prudential Financial”). Pruco Life is a stock life insurance company organized in 1971 under the laws of the State of Arizona. It is licensed to sell life insurance and annuities in the District of Columbia, Guam and in all states except New York, and sells such products primarily through affiliated and unaffiliated distributors. Pruco Life has one wholly-owned insurance subsidiary, Pruco Life Insurance Company of New Jersey (“PLNJ”). PLNJ is a stock life insurance company organized in 1982 under the laws of the State of New Jersey. It is licensed to sell life insurance and annuities in New Jersey and New York only. Pruco Life and its subsidiary are together referred to as the "Company", "we" or "our" and all financial information is shown on a consolidated basis. Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Intercompany balances and transactions have been eliminated. In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 . 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; policyholders' account balances related to the fair value of embedded derivative instruments associated with the index-linked features of certain universal life products; valuation of investments including derivatives, measurement of allowance for credit losses, and recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; reinsurance recoverables; 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. COVID-19 Beginning in the first quarter of 2020, the outbreak of the novel coronavirus (“COVID-19”) has resulted in extreme stress and disruption in the global economy and financial markets and has adversely impacted, and may continue to adversely impact, our results of operations, financial condition and cash flows. Due to the highly uncertain nature of these conditions, it is not possible to estimate the ultimate impacts at this time. The risks may have manifested, and may continue to manifest, in our financial statements in the areas of, among others, i) investments: increased risk of loss on our investments due to default or deterioration in credit quality or value; and ii) insurance liabilities and related balances: potential changes to assumptions regarding investment returns, mortality, morbidity and policyholder behavior which are reflected in our insurance liabilities and certain related balances (e.g., DAC, etc.). We cannot predict what impact the COVID-19 pandemic will ultimately have on the global economy, markets or our businesses. Revision to Prior Period Consolidated Financial Statements The Company identified an error in the presentation of certain cash flow activity related to policyholders' account balances that impacted several line items within previously issued Consolidated Statements of Cash Flows. Prior period amounts have been revised in the financial statements to correct this error. Management evaluated these adjustments and concluded they were not material to any previously reported quarterly or annual financial statements. See Note 11 for a more detailed description of the revision and for comparisons of amounts previously reported to the revised amounts. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Accounting Policies [Abstract]
Significant Accounting Policies and Pronouncements	SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of Accounting Standards Updates ("ASUs") to the FASB Accounting Standards Codification ("ASC"). The Company considers the applicability and impact of all ASUs. ASUs listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of June 30, 2020 , and as of the date of this filing. ASUs not listed below were assessed and determined to be either not applicable or not material. Adoption of ASU 2016-13 The Company adopted ASU 2016-13, and related ASUs, effective January 1, 2020 using the modified retrospective method for certain financial assets carried at amortized cost and certain off-balance sheet exposures. The modified retrospective method results in a cumulative effect adjustment to opening retained earnings. The Company adopted the guidance related to fixed maturities, available-for-sale on a prospective basis. This ASU requires the use of a new current expected credit loss (“CECL”) model to account for expected credit losses on certain financial assets reported at amortized cost (e.g., loans held for investment, reinsurance receivables, etc.) and certain off-balance sheet credit exposures (e.g., indemnification of serviced mortgage loans and certain loan commitments). The guidance requires an entity to estimate lifetime credit losses related to such financial assets and credit exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that may affect the collectability of the reported amounts. The standard also modifies the OTTI guidance for fixed maturities, available-for-sale requiring the use of an allowance rather than a direct write-down of the investment. The impacts of this ASU on the Company’s Consolidated Financial Statements primarily include (1) A Cumulative Effect Adjustment Upon Adoption; (2) Changes to the Presentation of the Consolidated Statements of Financial Position and Consolidated Statements of Operations; and (3) Changes to Accounting Policies. Each of these impacts is described below. This section is meant to serve as an update to, and should be read in conjunction with, Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. (1) Cumulative Effect Adjustment Upon Adoption Adoption of the standard resulted in a cumulative effect adjustment to opening retained earnings in the amount of $1.8 million , primarily related to commercial mortgage and other loans. The impact of adoption is not material to the following financial statement line items: deferred policy acquisition costs; reinsurance recoverables; income taxes receivable; future policy benefits; policyholders' account balances; and other liabilities. The prospective adoption of the portions of the standard related to fixed maturities, available-for-sale resulted in no impact to opening retained earnings. (2) Changes to the Presentation of the Consolidated Statements of Financial Position and Consolidated Statements of Operations The allowance for credit losses is presented parenthetically on relevant line items in the Consolidated Statements of Financial Position. In the Consolidated Statements of Operations, realized investment gains (losses), net are presented on one line item and will no longer reflect the breakout of OTTI on fixed maturity securities; OTTI on fixed maturity securities transferred to other comprehensive income (“OCI”); and other realized investment gains (losses), net. The presentation of this detail in prior periods is immaterial. (3) Changes to Accounting Policies This section has been updated to include the following changes in our accounting policies resulting from the adoption of ASU 2016-13. Fixed maturities, available-for-sale Fixed maturities, available-for-sale (“AFS debt securities”) are reported at fair value in the Statements of Financial Position. Interest income, and amortization of premium and accretion of discount are included in “Net investment income” under the effective yield method. For mortgage-backed and asset-backed securities, the effective yield is based on estimated cash flows, including interest rate and prepayment assumptions based on data from widely accepted third-party data sources or internal estimates. In addition to interest rate and prepayment assumptions, cash flow estimates also vary based on other assumptions relating to the underlying collateral, including default rates and changes in value. These assumptions can significantly impact income recognition and the amount of impairments recognized in earnings and OCI. For mortgage-backed and asset-backed securities rated below AA, the effective yield is adjusted prospectively for any changes in the estimated timing and amount of cash flows unless the investment is impaired or purchased with credit deterioration. For impaired mortgage-backed and asset-backed securities rated below AA, the effective yield is adjusted prospectively only if subsequent favorable or adverse changes in expected cash flows are not reflected in the allowance for credit losses. Prior to the adoption of this standard, the effective yield was adjusted prospectively regardless of whether the investment was impaired or not. AFS debt securities with unrealized losses are reviewed quarterly to determine whether the amortized cost basis of the security is recoverable. In evaluating whether the amortized cost basis is recoverable, the Company considers several factors including, but not limited to the extent of the decline and the reasons for the decline in value (credit events, currency or interest-rate related, including general credit spread widening), and the financial condition of the issuer. When an AFS debt security is in an unrealized loss position and (1) the Company has the intent to sell the AFS debt security, or (2) it is more likely than not the Company will be required to sell the AFS debt security before its anticipated recovery, or (3) the Company has deemed the AFS debt security to be uncollectable, the amortized cost basis of the AFS debt security is written down to fair value and any previously recognized allowance is reversed. The impairment is reported in “Realized investment gains (losses), net.” The new cost basis is not adjusted for subsequent increases in estimated fair value. For an AFS debt security in an unrealized loss position that does not meet these conditions, the Company analyzes its ability to recover the amortized cost by comparing the net present value of projected future cash flows (the “net present value”) with the amortized cost of the security. The net present value is calculated by discounting the Company’s best estimate of projected future cash flows at the effective interest rate implicit in the AFS debt security at the date of acquisition. The Company may use the estimated fair value of collateral, if any, as a proxy for the net present value if it believes that the security is dependent on the liquidation of collateral for recovery of its investment. If the net present value is less than the amortized cost of the investment, an allowance for losses is recognized in earnings for the difference between amortized cost and the net present value and is limited to the difference between amortized cost and fair value of the AFS debt security. Any difference between the fair value and the net present value of the debt security at the impairment measurement date remains in “Other comprehensive income (loss).” Changes in the allowance for losses are reported in “Realized investment gains (losses), net.” Prior to the adoption of this standard, any impairments on AFS debt securities were reported as an adjustment to the amortized cost basis of the security. Subsequent to the impairment, the AFS debt security was treated as if it were newly acquired at the date of impairment, and any increases in cash flows expected to be collected were accreted into net investment income over the life of the investment. Commercial mortgage and other loans Commercial mortgage and other loans are reported in the Statements of Financial Position at amortized cost net of the CECL allowance. Additionally, certain off-balance sheet credit exposures (e.g., indemnification of serviced mortgage loans, and certain unfunded mortgage loan commitments where the Company cannot unconditionally cancel the commitment) are also subject to a CECL allowance. The CECL allowance represents the Company’s best estimate of expected credit losses over the remaining life of the assets or off-balance sheet credit exposures. The determination of the allowance considers historical credit loss experience, current conditions, and reasonable and supportable forecasts. The allowance is calculated separately for commercial mortgage loans, agricultural mortgage loans, and other collateralized and uncollateralized loans. For commercial mortgage and agricultural mortgage loans (and related unfunded commitments where the Company cannot unconditionally cancel the commitment), the allowance is calculated using an internally developed CECL model. Key inputs to the CECL model include unpaid principal balances, internal credit ratings, annual expected loss factors, average lives of the loans adjusted for prepayment considerations, current and historical interest rate assumptions, and other factors influencing the Company’s view of the current stage of the economic cycle and future economic conditions. Subjective considerations include a review of whether historical loss experience is representative of current market conditions and the Company’s view of the credit cycle. Model assumptions and factors are reviewed and updated as appropriate. Information about certain key inputs is detailed below. Key factors in determining the internal credit ratings for commercial mortgage and agricultural mortgage loans include loan-to-value and debt-service-coverage ratios. Other factors include amortization, loan term, and estimated market value growth rate and volatility for the property type and region. The loan-to-value ratio compares the carrying amount of the loan to the fair value of the underlying property or properties collateralizing the loan and is commonly expressed as a percentage. Loan-to-value ratios greater than 100% indicate that the carrying amount of the loan exceeds the collateral value. A loan-to-value ratio less than 100% indicates an excess of collateral value over the carrying amount of the loan. The debt-service-coverage ratio is a property’s net operating income as a percentage of its debt service payments. Debt-service-coverage ratios less than 1.0 times indicate that a property’s operations do not generate enough income to cover the loan’s current debt payments. A debt-service-coverage ratio greater than 1.0 times indicates an excess of net operating income over the debt service payments. The values utilized in calculating these ratios are developed as part of the Company’s periodic review of the commercial mortgage and agricultural mortgage loan portfolios, which includes an internal appraisal of the underlying collateral value. The Company’s periodic review also includes a credit re-rating process, whereby the internal credit rating originally assigned at underwriting is updated based on current loan, property and market information using a proprietary credit quality rating system. See Note 3 for additional information related to the loan-to-value ratios and debt-service-coverage ratios related to the Company’s commercial mortgage and agricultural mortgage loan portfolios. Generally, every loan is re-rated at least annually. Annual expected loss rates are based on historical default and loss experience factors. Using average lives, the annual expected loss rates are converted into life-of-loan loss expectations. When individual loans no longer have the credit risk characteristics of the commercial or agricultural mortgage loan pools, they are removed from the pools and are evaluated individually for an allowance. The allowance is determined based on the outstanding loan balance less the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. The CECL allowance on commercial mortgage and other loans can increase or decrease from period to period based on the factors noted above. The change in allowance is reported in “Realized investment gains (losses), net.” As it relates to unfunded commitments that are in scope of this guidance, the CECL allowance is reported in “Other liabilities”, and the change in the allowance is reported in “Realized investment gains (losses), net.” When a commercial mortgage or other loan is deemed to be uncollectible, any allowance is reversed and a direct write-down of the carrying amount of the loan is recorded through "Realized investment gains (losses), net." The carrying amount of the loan is not adjusted for subsequent recoveries in value. The CECL allowance for other collateralized and uncollateralized loans carried at amortized cost is determined based on probability of default and loss given default assumptions by sector, credit quality and average lives of the loans. Additions to or releases of the allowance are reported in “Realized investment gains (losses), net.” Prior to the adoption of this standard, the impairments on commercial mortgage and other loans were collectively reviewed at a portfolio level for impairment based on probable incurred but not specifically identified losses with any such losses reflected in an allowance for credit losses. When a loan was individually identified to be impaired, the loan was individually evaluated for an allowance. Changes in these allowances were reported in “Realized investment gains (losses), net.” Additionally, an allowance for credit losses was not required on unfunded loan commitments. Reinsurance Reinsurance recoverables are reported on the Statements of Financial Position net of the CECL allowance. The CECL allowance considers the credit quality of the reinsurance counterparty and is generally determined based on the probability of default and loss given default assumptions, after considering any applicable collateral arrangements. The CECL allowance does not apply to reinsurance recoverables with affiliated counterparties under common control. Additions to or releases of the allowance are reported in “Policyholders’ benefits.” Prior to the adoption of this standard, an allowance for credit losses for reinsurance recoverables was established only when it was deemed probable that a reinsurer may fail to make payments to us in a timely manner. Other ASUs adopted during the six months ended June 30, 2020 . Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting This ASU provides optional relief for certain contracts impacted by reference rate reform. The standard permits an entity to consider contract modification due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The ASU also temporarily (until December 31, 2022) allows hedge relationships to continue without de-designation upon changes due to reference rate reform. March 12, 2020 to December 31, 2022 using the prospective method. This ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The Company made the election under ASU 2020-04 for all applicable contracts as they converted from the current reference rate to the new reference rate. ASU issued but not yet adopted as of June 30, 2020 — 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 October 2019, the FASB issued ASU 2019-09, Financial Services - Insurance (Topic 944): Effective Date to affirm its decision to defer the effective date of ASU 2018-12 to January 1, 2022 (with early adoption permitted), representing a one year extension from the original effective date of January 1, 2021. As a result of the COVID-19 pandemic, the FASB voted in June 2020 to tentatively defer for an additional one year the current effective date of ASU 2018-12 from January 1, 2022 to January 1, 2023, and to provide transition relief to facilitate the early adoption of the ASU. Subsequently in July 2020, the FASB issued a proposed ASU with a comment deadline of August 24, 2020 to obtain additional feedback on the tentative decisions, which are expected to be finalized during the third quarter of 2020. The transition relief would allow large calendar-year public companies that early adopt ASU 2018-12 to apply the guidance as of January 1, 2021 (and record transition adjustments as of January 1, 2021) in the 2022 financial statements. Companies that do not early adopt ASU 2018-12 would also apply the guidance as of January 1, 2021 (and record transition adjustments as of January 1, 2021) in the 2023 financial statements. ASU 2018-12 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 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 Accumulated Other Comprehensive Income (loss) ("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 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 DAC and other balances Requires DAC and other balances, such as unearned revenue reserves and deferred sales inducements ("DSI"), 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 liability for 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, and record market risk benefit assets and liabilities separately on the Statements of Financial Position. Changes in fair value of market risk benefits are recorded in net income, except for the portion of the change that is attributable to changes in an entity’s non-performance risk ("NPR") which is recognized in OCI. An entity shall adopt the guidance for market risk benefits using the retrospective transition method, which includes a cumulative-effect adjustment on the balance sheet as of the earliest period presented. An entity shall maximize the use of relevant observable information and minimize the use of unobservable information in determining the balance of the market risk benefits upon adoption. 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.

The following table sets forth the fair value and gross unrealized losses on available-for-sale fixed maturity securities without an allowance for credit losses aggregated by investment category and length of time that individual fixed maturity securities had been in a continuous unrealized loss position, as of the date indicated: June 30, 2020 Less Than Twelve Months Twelve Months or More Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in thousands) Fixed maturities, available-for-sale: Foreign government bonds $ 2,119 $ 42 $ 0 $ 0 $ 2,119 $ 42 U.S. public corporate securities 119,249 6,812 4,858 1,164 124,107 7,976 U.S. private corporate securities 85,321 4,514 3,772 287 89,093 4,801 Foreign public corporate securities 10,640 819 5,312 1,943 15,952 2,762 Foreign private corporate securities 148,434 5,474 192,258 26,330 340,692 31,804 Asset-backed securities 47,117 1,087 55,368 1,467 102,485 2,554 Commercial mortgage-backed securities 0 0 0 0 0 0 Residential mortgage-backed securities 83 0 0 0 83 0 Total fixed maturities, available-for-sale $ 412,963 $ 18,748 $ 261,568 $ 31,191 $ 674,531 $ 49,939 The following table sets forth the fair value and gross unrealized losses on fixed maturity securities aggregated by investment category and length of time that individual fixed maturity securities had been in a continuous unrealized loss position, as of the date indicated: December 31, 2019 Less Than Twelve Months Twelve Months or More Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in thousands) Fixed maturities, available-for-sale: Foreign government bonds $ 2,152 $ 1 $ 400 $ 0 $ 2,552 $ 1 U.S. public corporate securities 81,622 984 19,206 1,263 100,828 2,247 U.S. private corporate securities 33,264 780 22,143 226 55,407 1,006 Foreign public corporate securities 3,839 23 9,379 362 13,218 385 Foreign private corporate securities 32,800 921 186,693 18,630 219,493 19,551 Asset-backed securities 32,361 243 55,461 223 87,822 466 Commercial mortgage-backed securities 22,153 163 0 0 22,153 163 Residential mortgage-backed securities 3,049 16 692 8 3,741 24 Total fixed maturities, available-for-sale $ 211,240 $ 3,131 $ 293,974 $ 20,712 $ 505,214 $ 23,843 As of June 30, 2020 , the gross unrealized losses on fixed maturity available-for-sale securities without an allowance were composed of $31.9 million related to “1” highest quality or “2” high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $18.0 million , related to other than high or highest quality securities based on NAIC or equivalent rating. As of June 30, 2020 , the $31.2 million of gross unrealized losses of twelve months or more were concentrated in the Company’s corporate securities within the finance , energy and consumer non-cyclical sectors. As of December 31, 2019 , the gross unrealized losses on fixed maturity securities were composed of $16.0 million related to “1” highest quality or “2” high quality securities based on the NAIC or equivalent rating and $7.8 million related to other than high or highest quality securities based on NAIC or equivalent rating. As of December 31, 2019 , the $20.7 million of gross unrealized losses of twelve months or more were concentrated in the Company's corporate securities within the finance , energy and consumer non-cyclical sectors. In accordance with its policy described in Note 2, the Company concluded that an adjustment to earnings for credit losses related to these fixed maturity securities was not warranted at June 30, 2020 . 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, foreign currency exchange rate movements and the financial condition or near-term prospects of the issuer. As of June 30, 2020 , 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. The following table sets forth the amortized cost and fair value of fixed maturities by contractual maturities, as of the date indicated: June 30, 2020 Amortized Cost Fair Value (in thousands) Fixed maturities, available-for-sale: Due in one year or less $ 238,403 $ 240,471 Due after one year through five years 730,695 744,717 Due after five years through ten years 958,937 998,183 Due after ten years 3,001,873 3,465,247 Asset-backed securities 122,786 120,890 Commercial mortgage-backed securities 437,874 472,524 Residential mortgage-backed securities 59,732 64,290 Total fixed maturities, available-for-sale $ 5,550,300 $ 6,106,322 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 write-downs, impairments and the allowance for credit losses of fixed maturities, for the periods indicated: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 (in thousands) Fixed maturities, available-for-sale: Proceeds from sales(1) $ 5,223 $ 28,231 $ 12,941 $ 53,018 Proceeds from maturities/prepayments 55,968 75,554 137,754 128,429 Gross investment gains from sales and maturities 39 (1,384 ) 592 (435 ) Gross investment losses from sales and maturities (1,663 ) (1,105 ) (1,736 ) (3,075 ) OTTI recognized in earnings(2) N/A 0 N/A (3,163 ) Write-downs recognized in earnings(3) (77 ) N/A (1,022 ) N/A (Addition to) release of allowance for credit losses(4) $ (2,362 ) N/A (4,572 ) N/A (1) Includes $0.1 million and $2.1 million of non-cash related proceeds due to the timing of trade settlements for the six months ended June 30, 2020 and 2019 , respectively. (2) For the three and six months ended June 30, 2019 , amounts exclude 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) For the three and six months ended June 30, 2020 , amounts represent write-downs on securities approaching maturity related to foreign exchange movements and securities actively marketed for sale. (4) Effective January 1, 2020, credit losses on available-for-sale fixed maturity securities are recorded within the “allowance for credit losses.” The following table sets forth the activity in the allowance for credit losses for fixed maturity securities, as of the date indicated: June 30, 2020 U.S. Treasury Securities and Obligations of U.S. States Foreign Government Bonds U.S. and Foreign Corporate Securities Asset-Backed Securities Commercial Mortgage-Backed Securities Residential Mortgage-Backed Securities Total (in thousands) Fixed maturities, available-for-sale: Balance, beginning of year $ 0 $ 0 $ 0 $ 0 $ 0 $ 0 $ 0 Additions to allowance for credit losses not previously recorded 0 0 4,891 0 0 0 4,891 Reductions for securities sold during the period 0 0 (9 ) 0 0 0 (9 ) Addition (reductions) on securities with previous allowance 0 0 (310 ) 0 0 0 (310 ) Balance, end of period $ 0 $ 0 $ 4,572 $ 0 $ 0 $ 0 $ 4,572 See Note 2 for additional information about the Company’s methodology for developing our allowance and expected losses. As of June 30, 2020 , the allowance for credit losses on available-for-sale securities was primarily related to adverse projected cash flows on private corporate securities. The Company did not have any fixed maturity securities purchased with credit deterioration, as of June 30, 2020 . Equity Securities The net change in unrealized gains (losses) from equity securities still held at period end, recorded within “Other income,” was less than $(0.1) million and $(0.5) million during the three months ended June 30, 2020 and 2019 , respectively, and $(0.8) million and $0.2 million during the six months ended June 30, 2020 and 2019 , respectively.

Using June 30, 2020 values, it is estimated that a pre-tax gain of $9 million is expected to be reclassified from AOCI to earnings during the subsequent twelve months ending June 30, 2021 . The exposures the Company is hedging with these qualifying cash flow hedges include the variability of the payment or receipt of interest or foreign currency amounts on existing financial instruments. 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. Credit Derivatives The Company has no exposure from credit derivative positions where it has written credit protection as of June 30, 2020 and December 31, 2019 . The Company has purchased credit protection using credit derivatives in order to hedge specific credit exposures in the Company's investment portfolio. The Company has outstanding notional amounts of $2 million and $0 million reported as of June 30, 2020 and December 31, 2019 , respectively with a fair value of $0 million for both periods. Credit Risk The Company is exposed to losses in the event of non-performance by a counterparty to financial derivative transactions with a positive fair value. The Company manages credit risk by entering into derivative transactions with its affiliate, Prudential Global Funding LLC (“PGF”), related to its over-the-counter ("OTC") derivatives. PGF, in turn, manages its credit risk by: (i) entering into derivative transactions with highly rated major international financial institutions and other creditworthy counterparties governed by master netting agreement, as applicable; (ii) trading through central clearing and 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.

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 the Company's valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 5 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 . Assets and Liabilities by Hierarchy Level – The tables below present the balances of assets and liabilities reported at fair value on a recurring basis, as of the dates indicated.

(2) Includes credit-tranched securities collateralized by syndicated bank loans, sub-prime mortgages, auto loans, credit cards, education loans and other asset types. (3) Other invested assets excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. At June 30, 2020 and December 31, 2019 , the fair values of such investments were $71 million and $75 million , respectively. (4) 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. (5) 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 a corporate owned life insurance fund, for which fair value is measured at NAV per share (or its equivalent). At June 30, 2020 and December 31, 2019 , the fair value of such investments was $4,599 million and $4,762 million , respectively. (6) As of June 30, 2020 , the net embedded derivative liability position of $19,014 million includes $236 million of embedded derivatives in an asset position and $19,250 million of embedded derivatives in a liability position. As of December 31, 2019 , the net embedded derivative liability position of $8,530 million includes $611 million of embedded derivatives in an asset position and $9,141 million of embedded derivatives in a liability position. Quantitative Information Regarding Internally Priced Level 3 Assets and Liabilities – The tables below present quantitative information on significant internally-priced Level 3 assets and liabilities.

(2) Includes assets classified as fixed maturities and available-for-sale. (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) 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 a weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (5) Policyholders’ account balances primarily represent general account liabilities for the index-linked interest credited on certain of the Company’s life 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 a weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (6) 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. (7) 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. (8) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (9) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of June 30, 2020 and December 31, 2019 , the minimum withdrawal rate assumption is 76% and 78% respectively. As of June 30, 2020 and December 31, 2019 the maximum withdrawal rate assumption may be greater than 100% . The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%. (10) 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. Examples of such interrelationships for significant internally-priced Level 3 assets and liabilities are as follows: Corporate Securities – The rate used to discount future cash flows reflects current risk-free rates plus credit and liquidity spread requirements that market participants would use to value an asset. The discount rate may be influenced by many factors, including market cycles, expectations of default, collateral, term, and asset complexity. Each of these factors can influence discount rates, either in isolation, or in response to other factors. During weaker economic cycles, as the expectations of default increases, credit spreads widen, which results in a decrease in fair value. Future Policy Benefits – The Company expects efficient benefit utilization and withdrawal rates to generally be correlated with lapse rates. However, behavior is highly dependent on the facts and circumstances surrounding the individual contractholder, such as their liquidity needs or tax situation, which could drive lapse behavior independent of other contractholder behavior assumptions. To the extent more efficient contractholder behavior results in greater in-the-moneyness at the contract level, lapse rates may decline for those contracts. Similarly, to the extent that increases in equity volatility are correlated with overall declines in the capital markets, lapse rates may decline as contracts become more in-the-money. 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. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company determines its interim tax provision using the annual effective tax rate methodology as required by ASC 740-270. However, the Company has utilized a discrete effective tax rate method to calculate taxes for the six months ended June 30, 2020. The Company has determined that the use of this discrete method is more appropriate than the full year effective tax rate method. The variability inherent in the forecasted pretax income when combined with the forecasted permanent book-tax differences produces a result that a small change in pretax ordinary income will have a very significant impact on the forecasted effective tax rate. As a result, the Company has determined that the forecasted effective tax rate is unreliable. The Company's income tax provision, on a consolidated basis, amounted to an income tax benefit of $(56.5) million , or (108.84)% of income (loss) from operations before income taxes and equity in earnings of operating joint venture, in the first six months of 2020, compared to $(51.5) million , or (60.03)% , in the first six months of 2019. The Company's current and prior effective tax rates differed from the U.S. statutory tax rate of 21% primarily due to non-taxable investment income and tax credits. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted into law. One provision of the CARES Act amends the Tax Cuts and Jobs Act (“TCJA”) and allows companies with net operating losses (“NOLs”) originating in 2018, 2019 or 2020 to carry back those losses for five years. The Company has incorporated into the year-to-date effective tax rate an income tax benefit of $30 million that would result from carrying the estimated 2020 NOL back to tax years that have a 35% tax rate. This amount is an estimate and will change if the amount of, and sources of, 2020 net taxable income are different from forecast.

Reinsurance

Reinsurance Disclosures [Abstract]
Reinsurance	REINSURANCE The Company participates in reinsurance with its affiliates Prudential Life Insurance Company of Taiwan Inc. (“Prudential of Taiwan”), Prudential Arizona Reinsurance Captive Company (“PARCC”), Prudential Arizona Reinsurance Term Company (“PAR Term”), Prudential Arizona Reinsurance Universal Company (“PAR U”), Prudential Universal Reinsurance Company ("PURC"), Prudential Term Reinsurance Company (“Term Re”), PALAC, Gibraltar Universal Life Reinsurance Company ("GUL Re") and Dryden Arizona Reinsurance Term Company (“DART”), its parent company Prudential Insurance, as well as third parties. The reinsurance agreements provide risk diversification and additional capacity for future growth, limit the maximum net loss potential, manage statutory capital, and facilitate the Company's capital market hedging program. Life reinsurance is accomplished through various plans of reinsurance, primarily yearly renewable term and coinsurance. Reinsurance ceded arrangements do not discharge the Company as the primary insurer. Ceded balances would represent a liability of the Company in the event the reinsurers were unable to meet their obligations to the Company under the terms of the reinsurance agreements. The Company believes a material reinsurance liability resulting from such inability of reinsurers to meet their obligations is unlikely. Reserves related to reinsured long-duration contracts are accounted for using assumptions consistent with those used to account for the underlying contracts. Amounts recoverable from reinsurers for long-duration reinsurance arrangements are estimated in a manner consistent with the claim liabilities and policy benefits associated with the reinsured policies. Reinsurance policy charges and fee income ceded for universal life and variable annuity products are accounted for as a reduction of policy charges and fee income. Reinsurance premiums ceded for term insurance products are accounted for as a reduction of premiums. Realized investment gains and losses include the impact of reinsurance agreements, particularly reinsurance agreements involving living benefit guarantees. The Company has entered into reinsurance agreements to transfer the risk related to the living benefit guarantees on variable annuities to PALAC excluding the PLNJ business which was reinsured to Prudential Insurance. These reinsurance agreements are derivatives and have been accounted for in the same manner as embedded derivatives and the changes in the fair value of these derivatives are recognized through “Realized investment gains (losses), net”. See Note 4 for additional information related to the accounting for embedded derivatives. Reinsurance amounts included in the Company’s Unaudited Interim Consolidated Statements of Financial Position as of June 30, 2020 and December 31, 2019 were as follows: June 30, 2020 December 31, 2019 (in thousands) Reinsurance recoverables(1) $ 52,917,099 $ 40,710,159 Policy loans (151,049 ) (142,262 ) Deferred policy acquisition costs (6,779,267 ) (6,989,618 ) Deferred sales inducements (471,999 ) (515,968 ) Other assets(2) 257,709 258,427 Policyholders’ account balances 4,873,043 4,934,544 Future policy benefits(3) 4,697,373 4,209,817 Other liabilities(4) 995,122 884,641 (1) Includes $416.4 million and $156.7 million of unaffiliated activity as of June 30, 2020 and December 31, 2019 , respectively.

PAR U Pruco Life reinsures an amount equal to 70% of all the risks associated with Universal Protector policies having no-lapse guarantees as well as certain of its universal policies, with effective dates prior to January 1, 2011 . Effective July 1, 2012 , PLNJ reinsures an amount equal to 95% of all the risks associated with Universal Protector policies having no-lapse guarantees as well as certain of its universal policies, excluding those policies that are subject to principle-based reserving. On January 2, 2013 , Pruco Life began to assume Guaranteed Universal Life ("GUL") business from Prudential Insurance in connection with the acquisition of The Hartford Life Business. The GUL business assumed from Prudential Insurance was subsequently retroceded to PAR U. PALAC Effective April 1, 2016 , the Company entered into a reinsurance agreement to reinsure its variable annuity base contracts, along with the living benefit guarantees to PALAC, excluding the PLNJ business, which was reinsured to Prudential Insurance. This reinsurance agreement covers new and in force business and excludes business reinsured externally. PURC Pruco Life reinsures an amount equal to 70% of all the risks associated with its Universal Protector policies having no-lapse guarantees as well as certain of its universal policies, with effective dates from January 1, 2011 through December 31, 2013 , with PURC and 95% of all the risks associated with Universal Protector policies having no-lapse guarantees, as well as certain of its universal policies, with effective dates from January 1, 2014 through December 31, 2016 . PARCC Prior to July 1, 2019, the Company reinsured 90% of the risks under its term life insurance policies, with effective dates prior to January 1, 2010 through an automatic coinsurance agreement with PARCC. Effective July 1, 2019, the Company amended the coinsurance agreement to increase the percentage from 90% to 100% of the policy risk amount reinsured , which resulted in an initial transfer of $476 million in premiums and $409 million in expenses ceded with the difference being deferred and subsequently amortized through income. GUL Re Effective January 1, 2017 , Pruco Life entered into an automatic coinsurance agreement with GUL Re to reinsure an amount equal to 95% of all the risks associated with Universal Protector policies having no-lapse guarantees, as well as certain of its universal policies, with effective dates on or after January 1, 2017 through December 31, 2019 , excluding those policies that are subject to principle-based reserving. Effective July 1, 2017 , Pruco Life amended this agreement to include 30% of Universal Protector policies having no-lapse guarantees as well as certain of its universal policies with effective dates prior to January 1, 2014 . PAR Term Prior to July 1, 2019, the Company reinsures 95% of the risks under its term life insurance policies with effective dates January 1, 2010 through December 31, 2013 , through an automatic coinsurance agreement with PAR Term. Effective July 1, 2019, the Company amended the coinsurance agreement to increase the percentage from 95% to 100% of the policy risk amount reinsured , which resulted in an initial transfer of $150 million in premiums and $115 million in expenses ceded with the difference being deferred and subsequently amortized through income. Prudential of Taiwan On January 31, 2001 , Pruco Life transferred all of its assets and liabilities associated with its Taiwanese branch, including its Taiwanese insurance book of business, to Prudential of Taiwan, an affiliated company. The mechanism used to transfer this block of business in Taiwan is referred to as a “full acquisition and assumption” transaction. Under this mechanism, Pruco Life is jointly liable with Prudential of Taiwan for two years from the giving of notice to all obligees for all matured obligations and for two years after the maturity date of not-yet-matured obligations. Prudential of Taiwan is also contractually liable, under indemnification provisions of the transaction, for any liabilities that may be asserted against Pruco Life. The transfer of the insurance related assets and liabilities was accounted for as a long-duration coinsurance transaction under U.S. GAAP. Under this accounting treatment, the insurance related liabilities remain on the books of Pruco Life and an offsetting reinsurance recoverable is established. These assets and liabilities are denominated in U.S. dollars. On August 11, 2020, Prudential International Insurance Holdings, Ltd. (“PIIH”), a subsidiary of Prudential Financial, entered into a Share Purchase Agreement with Taishin Financial Holding Co., Ltd. (the “Buyer”) pursuant to which PIIH has agreed to sell to the Buyer all of the issued and outstanding capital stock of Prudential of Taiwan. Upon closing of the sale, which is subject to regulatory approval and the satisfaction of customary closing conditions, the Buyer will provide Pruco Life a backstop indemnification and Pruco Life will provide a guarantee to stand ready to perform in the event of default by both Prudential of Taiwan and the Buyer. Term Re The Company reinsures 95% of the risks under its term life insurance policies, with effective dates on or after January 1, 2014 through December 31, 2017 , through an automatic coinsurance agreement with Term Re. Prudential Insurance The Company has a yearly renewable term reinsurance agreement with Prudential Insurance and reinsures the majority of all mortality risks not otherwise reinsured. Effective July 1, 2017 , this agreement has been terminated for certain new business, primarily Universal Life insurance policies. As of January 1, 2020, the remaining portions of new business (specifically Term policies) ceased being reinsured by the Company to Prudential Insurance. Effective July 1, 2017 , the Company reinsures a portion of the mortality risk directly to third-party reinsurers and retains all of the non-reinsured portion of the mortality risk. Effective July 1, 2019, this agreement has been recaptured for certain term life insurance policies which are now reinsured to PARCC and PAR Term as noted above. On January 2, 2013 , Pruco Life began to assume GUL business from Prudential Insurance in connection with the acquisition of the Hartford Financial Services Group, Inc. ("Hartford Financial"). The GUL business assumed from Prudential Insurance was subsequently retroceded to PAR U. In May 2018, Hartford Financial sold a group of operating subsidiaries, which includes two of Prudential Insurance's counterparties to these reinsurance arrangements. There is no impact to the terms, rights or obligations of Prudential Insurance, or operation of these reinsurance arrangements, as a result of this change in control of such counterparties. Similarly, there is no impact to the Company's reinsurance arrangements with respect to such GUL business as a result of this change in control. The Company has reinsured a group annuity contract with Prudential Insurance, in consideration for a single premium payment by the Company, providing reinsurance equal to 100% of all payments due under the contract. Effective April 1, 2016, PLNJ entered into a reinsurance agreement to reinsure its variable annuity base contracts, along with the living benefit guarantees to Prudential Insurance. This reinsurance agreement covers new and in force business. DART Effective January 1, 2018 , the Company entered into an automatic coinsurance agreement with DART to reinsure an amount equal to 95% of the risks associated with its term life insurance policies with effective dates on or after January 1, 2018 through December 31, 2019 , excluding those policies that are subject to principle-based reserving. Information regarding significant third-party reinsurance arrangements is described below. Union Hamilton Between April 1, 2015 and December 31, 2016 , the Company, excluding its subsidiary, reinsured approximately 50% of the new business related to “highest daily” living benefits rider guarantees on HDI v.3.0 product, available with Prudential Premier ® Retirement Variable Annuity, to Union Hamilton. This reinsurance remains in force for the duration of the underlying annuity contracts. New sales of HDI v.3.0 subsequent to December 31, 2016 are not covered by this external reinsurance agreement. As of June 30, 2020 , $2.9 billion of HDI v.3.0 account values are reinsured to Union Hamilton.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS The Company has extensive transactions and relationships with Prudential Insurance and other affiliates. Although we seek to ensure that these transactions and relationships are fair and reasonable, it is possible that the terms of these transactions are not the same as those that would result from transactions among unrelated parties. Expense Charges and Allocations The majority of the Company’s expenses are allocations or charges from Prudential Insurance or other affiliates. These expenses can be grouped into general and administrative expenses and agency distribution expenses. The Company’s general and administrative expenses are charged to the Company using allocation methodologies based on business production processes. Management believes that the methodology is reasonable and reflects costs incurred by Prudential Insurance to process transactions on behalf of the Company. The Company operates under service and lease agreements whereby services of officers and employees, supplies, use of equipment and office space are provided by Prudential Insurance. The Company reviews its allocation methodology periodically which it may adjust accordingly. General and administrative expenses include allocations of stock compensation expenses related to a stock-based awards program and a deferred compensation program issued by Prudential Financial. The expense charged to the Company for the stock-based awards program was $0.4 million and $0.6 million for the three months ended June 30, 2020 , and 2019 , respectively, and $0.5 million and $0.7 million for the six months ended June 30, 2020 and 2019 , respectively. The expense charged to the Company for the deferred compensation program was $0.1 million and $1.2 million for the three months ended June 30, 2020 and 2019 , respectively, and $3.0 million and $3.9 million for the six months ended June 30, 2020 and 2019 , respectively. The Company is charged for its share of employee benefit expenses. These expenses include costs for funded and non-funded, non-contributory defined benefit pension plans. Some of these benefits are based on final earnings and length of service while others are based on an account balance, which takes into consideration age, service and earnings during a career. The Company’s share of net expense for the pension plans was $4 million and $5 million for the three months ended June 30, 2020 and 2019 , respectively, and $9 million and $10 million for the six months ended June 30, 2020 and 2019 , respectively. The Company is also charged for its share of the costs associated with welfare plans issued by Prudential Insurance. These expenses include costs related to medical, dental, life insurance and disability. The Company's share of net expense for the welfare plans was $3 million and $6 million for the three months ended June 30, 2020 and 2019 , respectively, and $9 million and $12 million for the six months ended June 30, 2020 and 2019 , respectively. Prudential Insurance sponsors voluntary savings plans for its employee 401(k) plans. The plans provide for salary reduction contributions by employees and matching contributions by the Company of up to 4% of annual salary. The Company’s expense for its share of the voluntary savings plan was $2 million for both the three months ended June 30, 2020 and 2019 , and $4 million and $5 million for the six months ended June 30, 2020 and 2019 , respectively. The Company is charged distribution expenses from Prudential Insurance’s agency network for both its domestic life and annuity products through a transfer pricing agreement, which is intended to reflect a market-based pricing arrangement. The Company pays commissions and certain other fees to Prudential Annuities Distributors, Inc. (“PAD”) in consideration for PAD’s marketing and underwriting of the Company’s annuity products. Commissions and fees are paid by PAD to broker-dealers who sell the Company’s annuity products. Commissions and fees paid by the Company to PAD were $129 million and $197 million for the three months ended June 30, 2020 and 2019 , respectively, and $297 million and $376 million for the six months ended June 30, 2020 and 2019 , respectively. The Company is charged for its share of corporate expenses incurred by Prudential Financial to benefit its businesses, such as advertising, executive oversight, external affairs and philanthropic activity. The Company’s share of corporate expenses was $6 million and $20 million for the three months ended June 30, 2020 and 2019 , respectively, and $25 million and $37 million for the six months ended June 30, 2020 and 2019 , respectively. Corporate-Owned Life Insurance The Company has sold five Corporate-Owned Life Insurance (“COLI”) policies to Prudential Insurance, and one to Prudential Financial. The cash surrender value included in separate accounts for these COLI policies was $4,207 million at June 30, 2020 and $4,339 million at December 31, 2019 . Fees related to these COLI policies were $11 million for both the three months ended June 30, 2020 and 2019 , and $25 million and $24 million for the six months ended June 30, 2020 and 2019 , respectively. The Company retains the majority of the mortality risk associated with these COLI policies up to $3.5 million per individual policy. Affiliated Investment Management Expenses In accordance with an agreement with PGIM, Inc. ("PGIM"), the Company pays investment management expenses to PGIM who acts as investment manager to certain Company general account and separate account assets. Investment management expenses paid to PGIM related to this agreement were $4 million and $3 million for the three months ended June 30, 2020 and 2019 , respectively, and $7 million for both the six months ended June 30, 2020 and 2019 .

Commitments and Contingent Liabilities	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES Commitments The Company has made commitments to fund commercial mortgage loans. As of June 30, 2020 and December 31, 2019 , the outstanding balances on these commitments were $37 million and $26 million , respectively. The above amount includes unfunded commitments that are not unconditionally cancellable. For related credit exposure, there was an allowance for credit losses of $0.0 million as of June 30, 2020 , which is a change of $0.0 million for the three and six months ended June 30, 2020 . The Company also made commitments to purchase or fund investments, mostly private fixed maturities. As of June 30, 2020 and December 31, 2019 , $357 million and $261 million , respectively, of these commitments were outstanding. The above amount includes unfunded commitments that are not unconditionally cancellable. There were no related charges for credit losses for both the three and six months ended June 30, 2020 . Guarantees In July 2017, the Company formed a joint venture with CT Corp to provide life insurance solutions in Indonesia. The Company owns a 49% interest in the joint venture and has entered into a shareholders agreement with CT Corp that sets out their respective rights and obligations with respect to the joint venture. Among other things, the shareholders agreement obligates the Company and CT Corp to provide capital to the joint venture, as necessary to comply with applicable law or to maintain a specified minimum amount of capital in the joint venture. This obligation is not limited to a maximum amount. The Company does not expect to make any payments on this guarantee and is not carrying any liabilities associated with the guarantee. 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 flows 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 flows 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 business. Pending legal and regulatory actions include proceedings specific to the Company and proceedings generally applicable to business practices in the industry in which it operates. The Company is subject to class action lawsuits and other litigation involving a variety of issues and allegations involving sales practices, claims payments and procedures, premium charges, policy servicing and breach of fiduciary duty to customers. The Company is also subject to litigation arising out of its general business activities, such as its investments, contracts, leases and labor and employment relationships, including claims of discrimination and harassment, and could be exposed to claims or litigation concerning certain business or process patents. In addition, the Company, along with other participants in the businesses in which it engages, may be subject from time to time to investigations, examinations and inquiries, in some cases industry-wide, concerning issues or matters upon which such regulators have determined to focus. In some of the Company’s pending legal and regulatory actions, parties are seeking large and/or indeterminate amounts, including punitive or exemplary damages. The outcome of litigation or a regulatory matter, and the amount or range of potential loss at any particular time, is often inherently uncertain. The Company establishes accruals for litigation and regulatory matters when it is probable that a loss has been incurred and the amount of that loss can be reasonably estimated. For litigation and regulatory matters where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established, but the matter, if material, is disclosed. The Company estimates that as of June 30, 2020 , 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 $100 million . This 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 14 to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 , and should be read in conjunction with the complete descriptions provided in the Form 10-K. Behfarin v. Pruco Life In June 2020, the court issued an order: (i) granting plaintiffs’ motion for certification of the settlement class; (ii) approving the proposed nationwide class settlement agreement; (iii) approving the class notice; (iv) awarding attorneys’ fees and costs to plaintiffs and a reduced incentive award to Behfarin; and (v) dismissing the action with prejudice, but maintaining jurisdiction over the settlement. 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 flows 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 flows 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.

Revision to Prior Year Informat

Revision to Prior Year Information	6 Months Ended

Prior Period Adjustment [Abstract]
Revision to Prior Year Information	REVISION TO PRIOR YEAR INFORMATION Revision to 2019 Consolidated Financial Statements The Company identified an error in the presentation of certain cash flow activity related to policyholders' account balances that impacted several line items within previously issued Consolidated Statements of Cash Flows. While these items affect the cash flows from operating and financing activities, they had no impact on the net increase (decrease) in cash and cash equivalents for the previously reported periods. Prior period amounts have been revised in the financial statements to correct this error as shown below. Management assessed the materiality of the misstatement described above on prior period financial statements in accordance with SEC Staff Accounting Bulletin ("SAB") No. 99, Materiality, codified in ASC 250-10, Accounting Changes and Error Corrections ("ASC 250"), and concluded that these misstatements were not material to any prior annual or interim periods. Accordingly, in accordance with ASC 250 (SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements), the consolidated financial statements for the six months ended June 30, 2019, which are presented herein, have been revised. Similarly, impacted prior periods presented within the Quarterly Report on Form 10-Q for the period ended September 30, 2020 and Annual Report on Form 10-K for the year ended December 31, 2020 will be revised. The following are selected line items from the consolidated financial statements illustrating the effects of these revisions: Consolidated Statements of Cash Flows Six Months Ended June 30, 2019 As Previously Reported Revision As Revised (in thousands) CASH FLOWS FROM OPERATING ACTIVITIES: Policy charges and fee income $ (135,809 ) $ 102,924 $ (32,885 ) Cash flows from (used in) operating activities (41,058 ) 102,924 61,866 CASH FLOWS FROM FINANCING ACTIVITIES: Policyholders' account withdrawals (1,712,728 ) (65,099 ) (1,777,827 ) Other, net 0 (37,825 ) (37,825 ) Cash flows from (used in) financing activities 446,736 (102,924 ) 343,812

Significant Accounting Polici_2

Significant Accounting Policies and Pronouncements (Policies)	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Intercompany balances and transactions have been eliminated. In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 .
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; policyholders' account balances related to the fair value of embedded derivative instruments associated with the index-linked features of certain universal life products; valuation of investments including derivatives, measurement of allowance for credit losses, and recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; reinsurance recoverables; 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	Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of Accounting Standards Updates ("ASUs") to the FASB Accounting Standards Codification ("ASC"). The Company considers the applicability and impact of all ASUs. ASUs listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of June 30, 2020 , and as of the date of this filing. ASUs not listed below were assessed and determined to be either not applicable or not material. Adoption of ASU 2016-13 The Company adopted ASU 2016-13, and related ASUs, effective January 1, 2020 using the modified retrospective method for certain financial assets carried at amortized cost and certain off-balance sheet exposures. The modified retrospective method results in a cumulative effect adjustment to opening retained earnings. The Company adopted the guidance related to fixed maturities, available-for-sale on a prospective basis. This ASU requires the use of a new current expected credit loss (“CECL”) model to account for expected credit losses on certain financial assets reported at amortized cost (e.g., loans held for investment, reinsurance receivables, etc.) and certain off-balance sheet credit exposures (e.g., indemnification of serviced mortgage loans and certain loan commitments). The guidance requires an entity to estimate lifetime credit losses related to such financial assets and credit exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that may affect the collectability of the reported amounts. The standard also modifies the OTTI guidance for fixed maturities, available-for-sale requiring the use of an allowance rather than a direct write-down of the investment. The impacts of this ASU on the Company’s Consolidated Financial Statements primarily include (1) A Cumulative Effect Adjustment Upon Adoption; (2) Changes to the Presentation of the Consolidated Statements of Financial Position and Consolidated Statements of Operations; and (3) Changes to Accounting Policies. Each of these impacts is described below. This section is meant to serve as an update to, and should be read in conjunction with, Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. (1) Cumulative Effect Adjustment Upon Adoption Adoption of the standard resulted in a cumulative effect adjustment to opening retained earnings in the amount of $1.8 million , primarily related to commercial mortgage and other loans. The impact of adoption is not material to the following financial statement line items: deferred policy acquisition costs; reinsurance recoverables; income taxes receivable; future policy benefits; policyholders' account balances; and other liabilities. The prospective adoption of the portions of the standard related to fixed maturities, available-for-sale resulted in no impact to opening retained earnings. (2) Changes to the Presentation of the Consolidated Statements of Financial Position and Consolidated Statements of Operations The allowance for credit losses is presented parenthetically on relevant line items in the Consolidated Statements of Financial Position. In the Consolidated Statements of Operations, realized investment gains (losses), net are presented on one line item and will no longer reflect the breakout of OTTI on fixed maturity securities; OTTI on fixed maturity securities transferred to other comprehensive income (“OCI”); and other realized investment gains (losses), net. The presentation of this detail in prior periods is immaterial. (3) Changes to Accounting Policies This section has been updated to include the following changes in our accounting policies resulting from the adoption of ASU 2016-13. Fixed maturities, available-for-sale Fixed maturities, available-for-sale (“AFS debt securities”) are reported at fair value in the Statements of Financial Position. Interest income, and amortization of premium and accretion of discount are included in “Net investment income” under the effective yield method. For mortgage-backed and asset-backed securities, the effective yield is based on estimated cash flows, including interest rate and prepayment assumptions based on data from widely accepted third-party data sources or internal estimates. In addition to interest rate and prepayment assumptions, cash flow estimates also vary based on other assumptions relating to the underlying collateral, including default rates and changes in value. These assumptions can significantly impact income recognition and the amount of impairments recognized in earnings and OCI. For mortgage-backed and asset-backed securities rated below AA, the effective yield is adjusted prospectively for any changes in the estimated timing and amount of cash flows unless the investment is impaired or purchased with credit deterioration. For impaired mortgage-backed and asset-backed securities rated below AA, the effective yield is adjusted prospectively only if subsequent favorable or adverse changes in expected cash flows are not reflected in the allowance for credit losses. Prior to the adoption of this standard, the effective yield was adjusted prospectively regardless of whether the investment was impaired or not. AFS debt securities with unrealized losses are reviewed quarterly to determine whether the amortized cost basis of the security is recoverable. In evaluating whether the amortized cost basis is recoverable, the Company considers several factors including, but not limited to the extent of the decline and the reasons for the decline in value (credit events, currency or interest-rate related, including general credit spread widening), and the financial condition of the issuer. When an AFS debt security is in an unrealized loss position and (1) the Company has the intent to sell the AFS debt security, or (2) it is more likely than not the Company will be required to sell the AFS debt security before its anticipated recovery, or (3) the Company has deemed the AFS debt security to be uncollectable, the amortized cost basis of the AFS debt security is written down to fair value and any previously recognized allowance is reversed. The impairment is reported in “Realized investment gains (losses), net.” The new cost basis is not adjusted for subsequent increases in estimated fair value. For an AFS debt security in an unrealized loss position that does not meet these conditions, the Company analyzes its ability to recover the amortized cost by comparing the net present value of projected future cash flows (the “net present value”) with the amortized cost of the security. The net present value is calculated by discounting the Company’s best estimate of projected future cash flows at the effective interest rate implicit in the AFS debt security at the date of acquisition. The Company may use the estimated fair value of collateral, if any, as a proxy for the net present value if it believes that the security is dependent on the liquidation of collateral for recovery of its investment. If the net present value is less than the amortized cost of the investment, an allowance for losses is recognized in earnings for the difference between amortized cost and the net present value and is limited to the difference between amortized cost and fair value of the AFS debt security. Any difference between the fair value and the net present value of the debt security at the impairment measurement date remains in “Other comprehensive income (loss).” Changes in the allowance for losses are reported in “Realized investment gains (losses), net.” Prior to the adoption of this standard, any impairments on AFS debt securities were reported as an adjustment to the amortized cost basis of the security. Subsequent to the impairment, the AFS debt security was treated as if it were newly acquired at the date of impairment, and any increases in cash flows expected to be collected were accreted into net investment income over the life of the investment. Commercial mortgage and other loans Commercial mortgage and other loans are reported in the Statements of Financial Position at amortized cost net of the CECL allowance. Additionally, certain off-balance sheet credit exposures (e.g., indemnification of serviced mortgage loans, and certain unfunded mortgage loan commitments where the Company cannot unconditionally cancel the commitment) are also subject to a CECL allowance. The CECL allowance represents the Company’s best estimate of expected credit losses over the remaining life of the assets or off-balance sheet credit exposures. The determination of the allowance considers historical credit loss experience, current conditions, and reasonable and supportable forecasts. The allowance is calculated separately for commercial mortgage loans, agricultural mortgage loans, and other collateralized and uncollateralized loans. For commercial mortgage and agricultural mortgage loans (and related unfunded commitments where the Company cannot unconditionally cancel the commitment), the allowance is calculated using an internally developed CECL model. Key inputs to the CECL model include unpaid principal balances, internal credit ratings, annual expected loss factors, average lives of the loans adjusted for prepayment considerations, current and historical interest rate assumptions, and other factors influencing the Company’s view of the current stage of the economic cycle and future economic conditions. Subjective considerations include a review of whether historical loss experience is representative of current market conditions and the Company’s view of the credit cycle. Model assumptions and factors are reviewed and updated as appropriate. Information about certain key inputs is detailed below. Key factors in determining the internal credit ratings for commercial mortgage and agricultural mortgage loans include loan-to-value and debt-service-coverage ratios. Other factors include amortization, loan term, and estimated market value growth rate and volatility for the property type and region. The loan-to-value ratio compares the carrying amount of the loan to the fair value of the underlying property or properties collateralizing the loan and is commonly expressed as a percentage. Loan-to-value ratios greater than 100% indicate that the carrying amount of the loan exceeds the collateral value. A loan-to-value ratio less than 100% indicates an excess of collateral value over the carrying amount of the loan. The debt-service-coverage ratio is a property’s net operating income as a percentage of its debt service payments. Debt-service-coverage ratios less than 1.0 times indicate that a property’s operations do not generate enough income to cover the loan’s current debt payments. A debt-service-coverage ratio greater than 1.0 times indicates an excess of net operating income over the debt service payments. The values utilized in calculating these ratios are developed as part of the Company’s periodic review of the commercial mortgage and agricultural mortgage loan portfolios, which includes an internal appraisal of the underlying collateral value. The Company’s periodic review also includes a credit re-rating process, whereby the internal credit rating originally assigned at underwriting is updated based on current loan, property and market information using a proprietary credit quality rating system. See Note 3 for additional information related to the loan-to-value ratios and debt-service-coverage ratios related to the Company’s commercial mortgage and agricultural mortgage loan portfolios. Generally, every loan is re-rated at least annually. Annual expected loss rates are based on historical default and loss experience factors. Using average lives, the annual expected loss rates are converted into life-of-loan loss expectations. When individual loans no longer have the credit risk characteristics of the commercial or agricultural mortgage loan pools, they are removed from the pools and are evaluated individually for an allowance. The allowance is determined based on the outstanding loan balance less the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. The CECL allowance on commercial mortgage and other loans can increase or decrease from period to period based on the factors noted above. The change in allowance is reported in “Realized investment gains (losses), net.” As it relates to unfunded commitments that are in scope of this guidance, the CECL allowance is reported in “Other liabilities”, and the change in the allowance is reported in “Realized investment gains (losses), net.” When a commercial mortgage or other loan is deemed to be uncollectible, any allowance is reversed and a direct write-down of the carrying amount of the loan is recorded through "Realized investment gains (losses), net." The carrying amount of the loan is not adjusted for subsequent recoveries in value. The CECL allowance for other collateralized and uncollateralized loans carried at amortized cost is determined based on probability of default and loss given default assumptions by sector, credit quality and average lives of the loans. Additions to or releases of the allowance are reported in “Realized investment gains (losses), net.” Prior to the adoption of this standard, the impairments on commercial mortgage and other loans were collectively reviewed at a portfolio level for impairment based on probable incurred but not specifically identified losses with any such losses reflected in an allowance for credit losses. When a loan was individually identified to be impaired, the loan was individually evaluated for an allowance. Changes in these allowances were reported in “Realized investment gains (losses), net.” Additionally, an allowance for credit losses was not required on unfunded loan commitments. Reinsurance Reinsurance recoverables are reported on the Statements of Financial Position net of the CECL allowance. The CECL allowance considers the credit quality of the reinsurance counterparty and is generally determined based on the probability of default and loss given default assumptions, after considering any applicable collateral arrangements. The CECL allowance does not apply to reinsurance recoverables with affiliated counterparties under common control. Additions to or releases of the allowance are reported in “Policyholders’ benefits.” Prior to the adoption of this standard, an allowance for credit losses for reinsurance recoverables was established only when it was deemed probable that a reinsurer may fail to make payments to us in a timely manner. Other ASUs adopted during the six months ended June 30, 2020 . Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting This ASU provides optional relief for certain contracts impacted by reference rate reform. The standard permits an entity to consider contract modification due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The ASU also temporarily (until December 31, 2022) allows hedge relationships to continue without de-designation upon changes due to reference rate reform. March 12, 2020 to December 31, 2022 using the prospective method. This ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. The Company made the election under ASU 2020-04 for all applicable contracts as they converted from the current reference rate to the new reference rate.
Future Adoption Of New Accounting Pronouncements	ASU issued but not yet adopted as of June 30, 2020 — 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 October 2019, the FASB issued ASU 2019-09, Financial Services - Insurance (Topic 944): Effective Date to affirm its decision to defer the effective date of ASU 2018-12 to January 1, 2022 (with early adoption permitted), representing a one year extension from the original effective date of January 1, 2021. As a result of the COVID-19 pandemic, the FASB voted in June 2020 to tentatively defer for an additional one year the current effective date of ASU 2018-12 from January 1, 2022 to January 1, 2023, and to provide transition relief to facilitate the early adoption of the ASU. Subsequently in July 2020, the FASB issued a proposed ASU with a comment deadline of August 24, 2020 to obtain additional feedback on the tentative decisions, which are expected to be finalized during the third quarter of 2020. The transition relief would allow large calendar-year public companies that early adopt ASU 2018-12 to apply the guidance as of January 1, 2021 (and record transition adjustments as of January 1, 2021) in the 2022 financial statements. Companies that do not early adopt ASU 2018-12 would also apply the guidance as of January 1, 2021 (and record transition adjustments as of January 1, 2021) in the 2023 financial statements. ASU 2018-12 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 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 Accumulated Other Comprehensive Income (loss) ("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 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 DAC and other balances Requires DAC and other balances, such as unearned revenue reserves and deferred sales inducements ("DSI"), 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 liability for 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, and record market risk benefit assets and liabilities separately on the Statements of Financial Position. Changes in fair value of market risk benefits are recorded in net income, except for the portion of the change that is attributable to changes in an entity’s non-performance risk ("NPR") which is recognized in OCI. An entity shall adopt the guidance for market risk benefits using the retrospective transition method, which includes a cumulative-effect adjustment on the balance sheet as of the earliest period presented. An entity shall maximize the use of relevant observable information and minimize the use of unobservable information in determining the balance of the market risk benefits upon adoption. 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.

(2) Includes credit-tranched securities collateralized by syndicated bank loans, sub-prime mortgages, auto loans, credit cards, education loans and other asset types. (3) Other invested assets excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. At June 30, 2020 and December 31, 2019 , the fair values of such investments were $71 million and $75 million , respectively. (4) 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. (5) 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 a corporate owned life insurance fund, for which fair value is measured at NAV per share (or its equivalent). At June 30, 2020 and December 31, 2019 , the fair value of such investments was $4,599 million and $4,762 million , respectively. (6) As of June 30, 2020 , the net embedded derivative liability position of $19,014 million includes $236 million of embedded derivatives in an asset position and $19,250 million of embedded derivatives in a liability position. As of December 31, 2019 , the net embedded derivative liability position of $8,530 million includes $611 million of embedded derivatives in an asset position and $9,141 million of embedded derivatives in a liability position.

(2) Includes assets classified as fixed maturities and available-for-sale. (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) 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 a weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (5) Policyholders’ account balances primarily represent general account liabilities for the index-linked interest credited on certain of the Company’s life 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 a weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (6) 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. (7) 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. (8) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (9) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of June 30, 2020 and December 31, 2019 , the minimum withdrawal rate assumption is 76% and 78% respectively. As of June 30, 2020 and December 31, 2019 the maximum withdrawal rate assumption may be greater than 100% . The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%. (10) 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. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.

Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement .
Fair Value, Liabilities 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. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.
