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 two subsidiaries, including one wholly-owned insurance subsidiary, Pruco Life Insurance Company of New Jersey (“PLNJ”) and one indirect subsidiary formed in 2009 for the purpose of holding certain commercial loan investments. Pruco Life and its subsidiaries are together referred to as the "Company", "we" or "our" and all financial information is shown on a consolidated basis. 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. Through March 31, 2016, the Company reinsured the majority of its variable annuity living benefit guarantees to an affiliated reinsurance company, Pruco Reinsurance, Ltd. ("Pruco Re"). Effective April 1, 2016, the Company recaptured the risks related to its variable annuity living benefit guarantees that were previously reinsured to Pruco Re. In addition, the Company reinsured variable annuity base contracts, along with the living benefit guarantees, to Prudential Annuities Life Assurance Corporation ("PALAC"), excluding the PLNJ business, which was reinsured to Prudential Insurance, in each case under a coinsurance and modified coinsurance agreement. These reinsurance agreements cover new and in force business and exclude business reinsured externally. The product risks related to the reinsured business are being managed in PALAC and Prudential Insurance, as applicable. In addition, the living benefit hedging program related to the reinsured living benefit guarantees is being managed within PALAC and Prudential Insurance, as applicable. These series of transactions are collectively referred to as the "Variable Annuities Recapture". The financial statement impacts of these transactions were as follows: Affected Financial Statement Lines Only Interim Statement of Financial Position Balance as of March 31, 2016 Impacts of Recapture Impacts of Reinsurance Total (in millions) ASSETS Total investments(1) $ 10,702 $ 4,166 $ (7,719 ) $ 7,149 Cash and cash equivalents 496 0 12 508 Deferred policy acquisition costs 4,565 0 (3,449 ) 1,116 Reinsurance recoverables 24,781 (6,312 ) 10,267 28,736 Deferred sales inducements 550 0 (550 ) 0 Other assets 94 0 211 305 Income taxes 0 0 23 23 TOTAL ASSETS 151,859 (2,146 ) (1,205 ) 148,508 LIABILITIES AND EQUITY LIABILITIES Income taxes $ 91 $ 17 $ 0 $ 108 Short-term and long-term debt to affiliates(2) 1,385 0 (1,384 ) 1 Other liabilities 870 0 0 870 TOTAL LIABILITIES 147,554 17 (1,384 ) 146,187 EQUITY Retained earnings(3) 3,337 (2,163 ) 258 1,432 Accumulated other comprehensive income 180 0 (79 ) 101 TOTAL EQUITY 4,305 (2,163 ) 179 2,321 TOTAL LIABILITIES AND EQUITY 151,859 (2,146 ) (1,205 ) 148,508 Significant Non-Cash Transactions (1) The decline in total investments includes non-cash activities of $7.7 billion for asset transfers related to the reinsurance transaction with PALAC and Prudential Insurance, partially offset by $4.2 billion of assets received related to the recapture transaction with Pruco Re. (2) The Company received ceding commissions of $3.6 billion and $0.4 billion from PALAC and Prudential Insurance, respectively, of which $1.1 billion and $0.1 billion were in the form of reassignment of debt to PALAC and Prudential Insurance, respectively. (3) Retained earnings includes dividends of $2.8 billion to Prudential Insurance, and then distributed to Prudential Financial, as part of the Variable Annuities Recapture.

As a result, the Company recognized a loss of $2.1 billion immediately. As part of the Variable Annuities Recapture, the Company transferred invested assets of $7 billion and $0.7 billion to PALAC and Prudential Insurance, respectively, and established reinsurance recoverables of $10.3 billion . In addition, the Company received ceding commissions of $3.6 billion and $0.4 billion from PALAC and Prudential Insurance, respectively, of which $1.1 billion and $0.1 billion were in the form of reassignment of debt to PALAC and Prudential Insurance, respectively. Also, the Company unwound its deferred policy acquisition costs ("DAC") and deferred sales inducements ("DSI") balances related to its variable annuity contracts as of March 31, 2016, which was equivalent to the ceding commission. For the reinsurance of the variable annuity base contracts, the Company recognized a loss of $0.2 billion , which was deferred and will subsequently be amortized through General, administrative and other expenses. For the reinsurance of the living benefit guarantees, the Company recognized a benefit of $2.8 billion immediately since the reinsurance contract is accounted for as a free-standing derivative. The Company paid a dividend of $2.6 billion to Prudential Insurance, which was then distributed to Prudential Financial.

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, 2016 . 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 DAC and related amortization; amortization of DSI; valuation of investments including derivatives and the 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 matters. Revision to Prior Period Consolidated Financial Statements In 2016, the Company identified errors in the calculation of reserves for certain individual life insurance products that impacted several line items within our previously issued consolidated financial statements. Prior period amounts have been revised in the Consolidated Financial Statements and related disclosures to correct these errors. In addition, the Company identified errors in the presentation of certain activity related to the Variable Annuities Recapture that impacted several line items within our previously issued Consolidated Statements of Cash Flows. While these items affect the subtotals of cash flows from operating, investing and financing activities, they have no impact on the net increase (decrease) in cash and cash equivalents for the previous reported periods. Prior period amounts presented have been revised. 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 revisions 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 Accounting for Certain Reinsurance Contracts in our Individual Life business During the second quarter of 2017, the Company recognized a pre-tax charge of $2 million , reflecting a change in estimate of reinsurance cash flows associated with universal life products as well as a change in method of reflecting these cash flows in the financial statements. Under the previous method of accounting, with the exception of recoveries pertaining to no lapse guarantees, reinsurance cash flows (e.g., premiums and recoveries) were generally recognized as they occurred. Under the new method, the expected reinsurance cash flows are recognized more ratably over the life of the underlying reinsured policies. In conjunction with this change, the way in which reinsurance is reflected in estimated gross profits used for the amortization of unearned revenue reserves and DAC was also revised. The change represents a change in accounting estimate effected by a change in accounting principle and is included within the Company’s annual reviews and update of assumptions and other refinements. The change in accounting estimate reflected insights gained from revised cash flow modeling enabled by a systems conversion, which prompted the change to a preferable accounting method. This new methodology is viewed as preferable as the Company believes it better reflects the economics of reinsurance transactions by aligning the results of reinsurance activity more closely to the underlying direct insurance activity and by better reflecting the profit pattern of this business for purposes of the amortization of the balances noted above. The impacts of the pre-tax charge of $2 million in the second quarter of 2017 were as follows: Impact of Change in Accounting for Certain Reinsurance Contracts(1) (in millions) Decrease in Policy charges and fee income $ (236 ) Decrease in Policyholders' benefits 253 Increase in Amortization of deferred policy acquisition costs (19 ) Pre-tax charge to income $ (2 ) (1) The corresponding impacts to the Consolidated Statement of Financial Position were a $284 million increase in "Other liabilities", a $247 million increase in "Reinsurance recoverables", a $48 million decrease in "Policyholders’ account balances", a $19 million decrease in "Deferred policy acquisition costs" and a $6 million decrease in "Future policy benefits". Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASU") to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASU. ASU listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASU not listed below were assessed and determined to be either not applicable or not material. There have been no ASU adopted during the six months ended June 30, 2017 . ASU issued but not yet adopted as of the reporting date June 30, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2014-09, Revenue from Contracts with Customers (Topic 606) The ASU is based on the core principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, and assets recognized from the costs to obtain or fulfill a contract with a customer. Revenue recognition for insurance contracts and financial instruments is explicitly scoped out of the standard. January 1, 2018 using the modified retrospective method. Given that insurance contracts and financial instruments are explicitly scoped out of the standard, the Company does not expect the adoption of the ASU to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-01 , The ASU revises an entity’s accounting related to the classification and measurement of certain equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. The standard also amends certain disclosure requirements associated with the fair value of financial instruments. January 1, 2018 using the modified retrospective method. The amendments are to be applied prospectively as they relate to equity investments without readily determinable fair value. The Company’s equity investments, except for those accounted for using the equity method, will generally be carried on the Consolidated Statements of Financial Position at fair value with changes in fair value reported in current earnings. The Company is continuing to assess additional impacts of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-13 , This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current other-than-temporary impairment standard for available-for-sale debt securities to require the use of an allowance rather than a direct write down of the investment, and replaces existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method, however prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an other-than-temporary-impairment was recognized prior to the date of adoption. Early adoption is permitted beginning January 1, 2019. The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-15 , This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows. January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Update 2016-18 , Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued this ASU to address diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities in the Statement of Cash Flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. January 1, 2018 using the retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. January 1, 2019 using the modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

Income Tax Disclosure [Abstract]
Income Tax	INCOME TAXES The Company uses a full year projected effective tax rate approach to calculate year-to-date taxes. In addition, certain items impacting total income tax expense are recorded in the periods in which they occur. The projected effective tax rate is the ratio of projected “Total income tax expense” divided by projected “Income from operations before income taxes”. Our income tax provision amounted to an income tax benefit of $29.6 million , or (8.2)% of income from operations before income taxes in the first six months of 2017, compared to a benefit of $39.1 million , or (10.9)% of income from operations before income taxes in the first six months of 2016. The Company’s current effective tax rate differed from the U.S. statutory rate of 35% primarily due to non-taxable investment income, tax credits, and domestic production activities deduction while its prior effective tax rate differed primarily due to non-taxable investment income and tax credits.

Fair Value of Assets and Liabil

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	FAIR VALUE OF ASSETS AND LIABILITIES Fair Value Measurement - Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative fair value guidance establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows: Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities. Level 2 – Fair value is based on significant inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, and other market observable inputs. Level 3 – Fair value is based on at least one significant unobservable input for the asset or liability. The assets and liabilities in this category may require significant judgment or estimation in determining the fair value. For a discussion of the Company's valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 . 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) 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. (3) As of June 30, 2017 , the net embedded derivative liability position of $6,425 million includes $467 million of embedded derivatives in an asset position and $6,892 million of embedded derivatives in a liability position. As of December 31, 2016 , the net embedded derivative liability position of $5,041 million includes $1,157 million of embedded derivatives in an asset position and $6,198 million of embedded derivatives in a liability position. (4) Includes credit tranched securities collateralized by sub-prime mortgages, auto loans, credit cards, education loans and other asset types. (5) Other long-term investments excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. At June 30, 2017 and December 31, 2016 , the fair values of such investments were $0.8 million and $0.9 million , respectively. (6) Separate account assets excluded from the fair value hierarchy, include investments in real estate and hedge funds, for which fair value is measured at NAV per share (or its equivalent) as a practical expedient. At June 30, 2017 and December 31, 2016 , the fair values of such investments were $713 million and $566 million , respectively. Transfers between Levels 1 and 2 – Transfers between levels are made to reflect changes in observability of inputs and market activity. Transfers into or out of any level are generally reported as the value as of the beginning of the quarter in which the transfers occur for any such assets still held at the end of the quarter. Periodically there are transfers between Level 1 and Level 2 for assets held in the Company’s Separate Account. During both the three and six months ended June 30, 2017 and 2016 , there were no transfers between Level 1 and Level 2. Quantitative Information Regarding Internally Priced Level 3 Assets and Liabilities – The tables below present quantitative information on significant internally-priced Level 3 assets and liabilities.

Mortality rate(11) 0 % 14 % Decrease Equity volatility curve 16 % 25 % Increase (1) Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table. (2) EBITDA multiples represent multiples of earnings before interest, taxes, depreciation and amortization, and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments. (3) For universal life, lapse rates vary based on funding level and other factors. Rates are set to zero when the no lapse guarantee is fully funded and the cash value is zero. (4) To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company and its affiliates, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. (5) Universal life mortality rates are adjusted based on underwriting information. A mortality improvement assumption is also incorporated into the projection. (6) For universal life, policyholders are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as “X”). The multiples vary by funding level and policy duration. If the resulting premium in any duration is smaller than the minimum annual premium required to maintain the no-lapse guarantee, policyholders are assumed to pay the minimum annual premium. Policyholders are assumed to stop premium payments once the no-lapse guarantee is fully funded. The range shown as of June 30, 2017 excludes multiples for the first duration since all contracts are beyond the first duration. Assumption ranges for prior periods include first duration multiples. (7) Future policy benefits primarily represent general account liabilities for the living benefit guarantees of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (8) Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. (9) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (10) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of June 30, 2017 and December 31, 2016 , the minimum withdrawal assumption rate is 78% and the maximum withdrawal assumption rate may be greater than 100% . The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%. (11) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table. (12) Includes assets classified as fixed maturities, available-for-sale. Interrelationships Between Unobservable Inputs – In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another, or multiple, inputs. For discussion of the relationships between unobservable inputs as well as market factors that may affect the range of inputs used in the valuation of Level 3 assets and liabilities, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 . Changes in Level 3 assets and liabilities – The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on the significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within the valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate. For further information on valuation processes, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 .

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

For both the three and six months ended June 30, 2017 and 2016 , the ineffective portion of derivatives accounted for using hedge accounting was not material to the Company’s results of operations. Also, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging. Presented below is a rollforward of current period cash flow hedges in “Accumulated other comprehensive income (loss)” before taxes: (in thousands) Balance, December 31, 2016 $ 40,931 Net deferred gains (losses) on cash flow hedges from January 1 to June 30, 2017 (21,926 ) Amounts reclassified into current period earnings (787 ) Balance, June 30, 2017 $ 18,218 Using June 30, 2017 values, it is estimated that a pre-tax loss of $5 million will be reclassified from AOCI to earnings during the subsequent twelve months ending June 30, 2018 , offset by amounts pertaining to the hedged items. As of June 30, 2017 , the Company did not have any qualifying cash flow hedges of forecasted transactions other than those related to the variability of the payment or receipt of interest or foreign currency amounts on existing financial instruments. The maximum length of time for which these variable cash flows are hedged is 40 years . Income amounts deferred in AOCI as a result of cash flow hedges are included in “Net unrealized investment gains (losses)” within OCI in the Unaudited Interim Consolidated Statements of Operations and Comprehensive Income (Loss). Credit Derivatives As of June 30, 2017 and December 31, 2016 , the Company has not written credit protection. 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 $3 million reported at fair value as a liability of $0.1 million and $0.3 million as of June 30, 2017 and December 31, 2016 , respectively. Credit Risk The Company is exposed to credit-related losses in the event of non-performance by counterparty to financial derivative transactions. The Company has credit risk exposure to an affiliate, Prudential Global Funding, LLC (“PGF”), related to its OTC derivative transactions. PGF manages credit risk with external counterparties by entering into derivative transactions with highly rated major international financial institutions and other creditworthy counterparties, and by obtaining collateral, such as cash and securities, when appropriate. Additionally, limits are set on single party credit exposures which are subject to periodic management review. Under fair value measurements, the Company incorporates the market’s perception of its own and the counterparty’s non-performance risk in determining the fair value of the portion of its OTC derivative assets and liabilities that are uncollateralized. Credit spreads are applied to the derivative fair values on a net basis by counterparty. To reflect the Company’s own credit spread, a proxy based on relevant debt spreads is applied to OTC derivative net liability positions. Similarly, the Company’s counterparty’s credit spread is applied to OTC derivative net asset positions.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingent Liabilities And Litigation And Regulatory Matters	COMMITMENTS, CONTINGENT LIABILITIES AND LITIGATION AND REGULATORY MATTERS Commitments The Company has made commitments to fund commercial loans. As of June 30, 2017 and December 31, 2016 , the outstanding balances on these commitments were $37 million and $49 million , respectively. The Company also made commitments to purchase or fund investments, mostly private fixed maturities. As of June 30, 2017 and December 31, 2016 , $332 million and $133 million , respectively, of these commitments were outstanding. Contingent Liabilities On an ongoing basis, the Company’s internal supervisory and control functions review the quality of sales, marketing and other customer interface procedures and practices and may recommend modifications or enhancements. From time to time, this review process results in the discovery of product administration, servicing or other errors, including errors relating to the timing or amount of payments or contract values due to customers. In certain cases, if appropriate, the Company may offer customers 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, including matters discussed below. The Company estimates that as of June 30, 2017 , the aggregate range of reasonably possible losses in excess of accruals established for those litigation and regulatory matters for which such an estimate currently can be made is less than $30 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. For a discussion of the Company's litigations and regulatory matters, see Note 11 to the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . 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.

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”), UPARC, 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"), its parent company Prudential Insurance, as well as third parties, and participated in reinsurance with its affiliate Pruco Re through March 31, 2016. The reinsurance agreements provide risk diversification and additional capacity for future growth, limit the maximum net loss potential, manage statutory capital, facilitate its capital market hedging program, and align accounting methodology for the assets and liabilities of living benefit guarantees contained in annuities contracts. See Note 1 for additional information on the change effective April 1, 2016 related to the Variable Annuities Recapture. 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 premiums ceded for universal life 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. See Note 1 for additional information on the change effective April 1, 2016 related to the Variable Annuities Recapture. The Company has also entered into an agreement with UPARC to reinsure a portion of the no-lapse guarantee provision on certain universal life products. 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 6 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, 2017 and December 31, 2016 were as follows: June 30, 2017 December 31, 2016 (in thousands) Reinsurance recoverables $ 31,695,151 $ 28,674,226 Policy loans (89,978 ) (87,112 ) Deferred policy acquisition costs (6,855,073 ) (6,482,889 ) Deferred sales inducements (684,452 ) (615,117 ) Other assets(1) 243,994 226,347 Policyholders’ account balances 4,993,261 4,978,859 Future policy benefits 3,056,354 2,833,327 Other liabilities(2) 379,104 410,376 (1) “Other assets” includes $0.1 million of unaffiliated activity as of both June 30, 2017 and December 31, 2016 .

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.

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 Many 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 option program and a deferred compensation program issued by Prudential Financial. The expense charged to the Company for the stock option program was $0.5 million and $0.4 million for the three months ended June 30, 2017 and 2016 , respectively, and $0.7 million and $0.6 million for the six months ended June 30, 2017 and 2016 , respectively. The expense charged to the Company for the deferred compensation program was $2 million for both the three months ended June 30, 2017 and 2016 , and $5 million and $3 million for the six months ended June 30, 2017 and 2016 , respectively. The Company is charged for its share of employee benefit expenses. These expenses include costs for funded and non-funded contributory and 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 $6 million for both the three months ended June 30, 2017 and 2016 , and $13 million and $12 million for the six months ended June 30, 2017 and 2016 , 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 $7 million for both the three months ended June 30, 2017 and 2016 , and $14 million for both the six months ended June 30, 2017 and 2016 . 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 $3 million and $2 million for the three months ended June 30, 2017 and 2016 , respectively, and $5 million for both the six months ended June 30, 2017 and 2016 . 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, Incorporated (“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 $160 million and $190 million for the three months ended June 30, 2017 and 2016 , respectively, and $315 million and $364 million for the six months ended June 30, 2017 and 2016 , 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 $15 million and $13 million for the three months ended June 30, 2017 and 2016 , respectively, and $32 million and $28 million for the six months ended June 30, 2017 and 2016 , 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 $3,600 million at June 30, 2017 and $3,367 million at December 31, 2016 . Fees related to these COLI policies were $11 million and $10 million for the three months ended June 30, 2017 and 2016 , respectively, and $23 million and $21 million for the six months ended June 30, 2017 and 2016 , respectively. The Company retains the majority of the mortality risk associated with these COLI policies up to $3.5 million .

("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 for both the three months ended June 30, 2017 and 2016 , and $7 million and $9 million for the six months ended June 30, 2017 and 2016 , respectively. These expenses are recorded as “Net investment income” in the Company's Unaudited Interim Consolidated Statements of Operations and Comprehensive Income (Loss).

Prior Period Adjustment [Abstract]
Revision to Prior Year Information	REVISION TO PRIOR YEAR INFORMATION Revisions to 2016 Consolidated Financial Statements In 2016, the Company identified errors in the calculation of reserves for certain individual life insurance products that impacted several line items within our previously issued consolidated financial statements. Prior period amounts have been revised in the Consolidated Financial Statements and related disclosures to correct these errors. In addition, the Company identified errors in the presentation of certain activity related to the Variable Annuities Recapture that impacted several line items within our previously issued Consolidated Statements of Cash Flows. While these items affect the subtotals of cash flows from operating, investing 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 and the related disclosures to correct these errors. Management evaluated these adjustments and concluded they were not material to any previously reported quarterly financial statements. Management assessed the materiality of the misstatements described above on prior period financial statements in accordance with SEC Staff Accounting Bulletin ("SAB") No. 99, Materiality, codified in Accounting Standards Codification ("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 interim consolidated financial statements as of and for the three and six months ended June 30, 2016 , which are presented herein, have been revised. The following are selected line items from the interim consolidated financial statements illustrating the effects of these revisions: Consolidated Statements of Operations and Comprehensive Income (Loss) (UNAUDITED) Three Months Ended June 30, 2016 As Previously Reported Revision As Revised (in thousands) REVENUES Policy charges and fee income $ 41,848 $ 17,083 $ 58,931 TOTAL REVENUES 123,842 17,083 140,925 BENEFITS AND EXPENSES Policyholders' benefits (430,437 ) (42,173 ) (472,610 ) Amortization of deferred policy acquisition costs (29,866 ) 19,524 (10,342 ) TOTAL BENEFITS AND EXPENSES (565,465 ) (22,649 ) (588,114 ) INCOME (LOSS) FROM OPERATIONS BEFORE INCOME TAXES 689,307 39,732 729,039 Income tax expense (benefit) (5,499 ) 10,554 5,055 NET INCOME (LOSS) 694,806 29,178 723,984 COMPREHENSIVE INCOME (LOSS) 755,691 29,178 784,869 (UNAUDITED) Six Months Ended June 30, 2016 As Previously Reported Revision As Revised (in thousands) REVENUES Policy charges and fee income $ 569,255 $ 16,238 $ 585,493 TOTAL REVENUES 916,080 16,238 932,318 BENEFITS AND EXPENSES Policyholders' benefits (331,909 ) (39,971 ) (371,880 ) Amortization of deferred policy acquisition costs 610,687 18,558 629,245 TOTAL BENEFITS AND EXPENSES 596,999 (21,413 ) 575,586 INCOME (LOSS) FROM OPERATIONS BEFORE INCOME TAXES 319,081 37,651 356,732 Income tax expense (benefit) (49,594 ) 10,541 (39,053 ) NET INCOME (LOSS) 368,675 27,110 395,785 COMPREHENSIVE INCOME (LOSS) 544,886 27,110 571,996 Consolidated Statements of Equity (UNAUDITED) Retained Earnings Total Equity As Previously Reported Revision As Revised As Previously Reported Revision As Revised (in thousands) Balance, December 31, 2015 $ 3,663,539 $ (28,392 ) $ 3,635,147 $ 4,510,817 $ (28,392 ) $ 4,482,425 Comprehensive income (loss): Net income (loss) 368,675 27,110 395,785 368,675 27,110 395,785 Total comprehensive income (loss) 544,886 27,110 571,996 Balance, June 30, 2016 1,438,695 (1,282 ) 1,437,413 2,668,274 (1,282 ) 2,666,992 Consolidated Statements of Cash Flows (UNAUDITED) Six Months Ended June 30, 2016 As Previously Reported Revision As Revised (in thousands) CASH FLOWS FROM OPERATING ACTIVITIES: Net income (loss) $ 368,675 $ 27,110 $ 395,785 Policy charges and fee income 78,763 (16,238 ) 62,525 Future policy benefits 659,730 (154,908 ) 504,822 Reinsurance recoverables (326,993 ) 1,434 (325,559 ) Deferred policy acquisition costs 408,155 18,558 426,713 Income taxes (78,531 ) 10,541 (67,990 ) Other, net (181,862 ) (78,333 ) (260,195 ) Cash flows from (used in) operating activities 5,386 (191,836 ) (186,450 ) CASH FLOWS FROM INVESTING ACTIVITIES: Proceeds from the sale/maturity/prepayment of: Fixed maturities, available-for-sale 798,298 40,000 838,298 Cash flows from (used in) investing activities (537,625 ) 40,000 (497,625 ) CASH FLOWS FROM FINANCING ACTIVITIES: Ceded policyholders’ account deposits (584,464 ) (539,144 ) (1,123,608 ) Ceded policyholders’ account withdrawals 32,053 490,659 522,712 Contributed capital 205,000 200,321 405,321 Cash flows from (used in) financing activities 488,765 151,836 640,601

Significant Accounting Polici19

Significant Accounting Policies and Pronouncements (Policies)	6 Months Ended

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, 2016 .
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 DAC and related amortization; amortization of DSI; valuation of investments including derivatives and the 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 matters.
Revision to Prior Period Consolidated Financial Statements	Revision to Prior Period Consolidated Financial Statements In 2016, the Company identified errors in the calculation of reserves for certain individual life insurance products that impacted several line items within our previously issued consolidated financial statements. Prior period amounts have been revised in the Consolidated Financial Statements and related disclosures to correct these errors. In addition, the Company identified errors in the presentation of certain activity related to the Variable Annuities Recapture that impacted several line items within our previously issued Consolidated Statements of Cash Flows. While these items affect the subtotals of cash flows from operating, investing and financing activities, they have no impact on the net increase (decrease) in cash and cash equivalents for the previous reported periods. Prior period amounts presented have been revised. 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 revisions and for comparisons of amounts previously reported to the revised amounts.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
Accounting for Certain Reinsurance Contracts in our Individual Life business	Accounting for Certain Reinsurance Contracts in our Individual Life business During the second quarter of 2017, the Company recognized a pre-tax charge of $2 million , reflecting a change in estimate of reinsurance cash flows associated with universal life products as well as a change in method of reflecting these cash flows in the financial statements. Under the previous method of accounting, with the exception of recoveries pertaining to no lapse guarantees, reinsurance cash flows (e.g., premiums and recoveries) were generally recognized as they occurred. Under the new method, the expected reinsurance cash flows are recognized more ratably over the life of the underlying reinsured policies. In conjunction with this change, the way in which reinsurance is reflected in estimated gross profits used for the amortization of unearned revenue reserves and DAC was also revised. The change represents a change in accounting estimate effected by a change in accounting principle and is included within the Company’s annual reviews and update of assumptions and other refinements. The change in accounting estimate reflected insights gained from revised cash flow modeling enabled by a systems conversion, which prompted the change to a preferable accounting method. This new methodology is viewed as preferable as the Company believes it better reflects the economics of reinsurance transactions by aligning the results of reinsurance activity more closely to the underlying direct insurance activity and by better reflecting the profit pattern of this business for purposes of the amortization of the balances noted above.
Accounting Standard Updates Pronouncements	Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASU") to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASU. ASU listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASU not listed below were assessed and determined to be either not applicable or not material. There have been no ASU adopted during the six months ended June 30, 2017 . ASU issued but not yet adopted as of the reporting date June 30, 2017 Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2014-09, Revenue from Contracts with Customers (Topic 606) The ASU is based on the core principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, and assets recognized from the costs to obtain or fulfill a contract with a customer. Revenue recognition for insurance contracts and financial instruments is explicitly scoped out of the standard. January 1, 2018 using the modified retrospective method. Given that insurance contracts and financial instruments are explicitly scoped out of the standard, the Company does not expect the adoption of the ASU to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-01 , The ASU revises an entity’s accounting related to the classification and measurement of certain equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. The standard also amends certain disclosure requirements associated with the fair value of financial instruments. January 1, 2018 using the modified retrospective method. The amendments are to be applied prospectively as they relate to equity investments without readily determinable fair value. The Company’s equity investments, except for those accounted for using the equity method, will generally be carried on the Consolidated Statements of Financial Position at fair value with changes in fair value reported in current earnings. The Company is continuing to assess additional impacts of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. ASU 2016-13 , This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current other-than-temporary impairment standard for available-for-sale debt securities to require the use of an allowance rather than a direct write down of the investment, and replaces existing standard for purchased credit deteriorated loans and debt securities. January 1, 2020 using the modified retrospective method, however prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an other-than-temporary-impairment was recognized prior to the date of adoption. Early adoption is permitted beginning January 1, 2019. The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Standard Description Effective date and method of adoption Effect on the financial statements or other significant matters ASU 2016-15 , This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows. January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements. Update 2016-18 , Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued this ASU to address diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities in the Statement of Cash Flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories will no longer be presented in the Statement of Cash Flows. January 1, 2018 using the retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. January 1, 2019 using the modified retrospective method (with early adoption permitted). The Company is currently assessing the impact of the ASU on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

(2) 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. (3) As of June 30, 2017 , the net embedded derivative liability position of $6,425 million includes $467 million of embedded derivatives in an asset position and $6,892 million of embedded derivatives in a liability position. As of December 31, 2016 , the net embedded derivative liability position of $5,041 million includes $1,157 million of embedded derivatives in an asset position and $6,198 million of embedded derivatives in a liability position. (4) Includes credit tranched securities collateralized by sub-prime mortgages, auto loans, credit cards, education loans and other asset types. (5) Other long-term investments excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. At June 30, 2017 and December 31, 2016 , the fair values of such investments were $0.8 million and $0.9 million , respectively. (6) Separate account assets excluded from the fair value hierarchy, include investments in real estate and hedge funds, for which fair value is measured at NAV per share (or its equivalent) as a practical expedient. At June 30, 2017 and December 31, 2016 , the fair values of such investments were $713 million and $566 million , respectively.

Mortality rate(11) 0 % 14 % Decrease Equity volatility curve 16 % 25 % Increase (1) Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table. (2) EBITDA multiples represent multiples of earnings before interest, taxes, depreciation and amortization, and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments. (3) For universal life, lapse rates vary based on funding level and other factors. Rates are set to zero when the no lapse guarantee is fully funded and the cash value is zero. (4) To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company and its affiliates, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. (5) Universal life mortality rates are adjusted based on underwriting information. A mortality improvement assumption is also incorporated into the projection. (6) For universal life, policyholders are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as “X”). The multiples vary by funding level and policy duration. If the resulting premium in any duration is smaller than the minimum annual premium required to maintain the no-lapse guarantee, policyholders are assumed to pay the minimum annual premium. Policyholders are assumed to stop premium payments once the no-lapse guarantee is fully funded. The range shown as of June 30, 2017 excludes multiples for the first duration since all contracts are beyond the first duration. Assumption ranges for prior periods include first duration multiples. (7) Future policy benefits primarily represent general account liabilities for the living benefit guarantees of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (8) Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. (9) The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits. (10) The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of June 30, 2017 and December 31, 2016 , the minimum withdrawal assumption rate is 78% and the maximum withdrawal assumption rate may be greater than 100% . The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%. (11) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table. (12) Includes assets classified as fixed maturities, available-for-sale.

Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on the significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within the valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.

Fair Value, Liabilities Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables provide summaries of the changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on the significance of the unobservable inputs in the overall fair value measurement. Transfers into Level 3 are generally the result of unobservable inputs utilized within the valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate. For further information on valuation processes, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 .

Fair Value Disclosure Financial Instruments Not Carried at Fair Value	The table below presents the carrying amount and fair value by fair value hierarchy level of certain financial instruments that are not reported at fair value.
