FORWARD LOOKING STATEMENTS

Certain of the statements included in this Quarterly Report on Form 10-Q, including but not limited to those in Management’s Discussion and Analysis of Financial Condition and Results of Operations, constitute forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Words such as “expects,” “believes,” “anticipates,” “includes,” “plans,” “assumes,” “estimates,” “projects,” “intends,” “should,” “will,” “shall” or variations of such words are generally part of forward-looking statements. Forward-looking statements are made based on management’s current expectations and beliefs concerning future developments and their potential effects upon Pruco Life Insurance Company and its subsidiaries. There can be no assurance that future developments affecting Pruco Life Insurance Company and its subsidiaries will be those anticipated by management. These forward-looking statements are not a guarantee of future performance and involve risks and uncertainties, and there are certain important factors that could cause actual results to differ, possibly materially, from expectations or estimates reflected in such forward-looking statements, including, among others: (1) losses on investments or financial contracts due to deterioration in credit quality or value, or counterparty default; (2) losses on insurance products due to mortality experience or policyholder behavior experience that differs significantly from our expectations when we price our products; (3) changes in interest rates and equity prices that may (a) adversely impact the profitability of our products, the value of separate accounts supporting these products or the value of assets we manage, (b) result in losses on derivatives we use to hedge risk or increase collateral posting requirements and (c) limit opportunities to invest at appropriate returns; (4) guarantees within certain of our products, in particular our variable annuities, which are market sensitive and may decrease our earnings or increase the volatility of our results of operations or financial position; (5) liquidity needs resulting from (a) derivative collateral market exposure, (b) asset/liability mismatches, (c) the lack of available funding in the financial markets or (d) unexpected cash demands due to severe mortality calamity or lapse events; (6) financial or customer losses, or regulatory and legal actions, due to inadequate or failed processes or systems, human error or misconduct, and external events, such as (a) disruption of our systems and data, (b) an information security breach, (c) a failure to protect the privacy of sensitive data or (d) reliance on third-parties, including to distribute our products; (7) changes in the regulatory landscape, including related to (a) regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (b) changes in tax laws, (c) fiduciary rule developments, (d) state insurance laws and developments regarding group-wide supervision, capital and reserves, and (e) privacy and cybersecurity regulation; (8) technological changes which may adversely impact companies in our investment portfolio or cause insurance experience to deviate from our assumptions; (9) ratings downgrades; (10) market conditions that may adversely affect the sales or persistency of our products; (11) competition; and (12) reputational damage. Pruco Life Insurance Company does not intend, and is under no obligation, to update any particular forward-looking statement included in this document.

PRUCO LIFE INSURANCE COMPANY

Notes to Unaudited Interim Consolidated Financial Statements

1.    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 and other 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.

Variable Annuities Recapture

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 coinsurance and modified coinsurance agreements. 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".

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, 2017.

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 and related amortization; amortization of deferred sales inducements; 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 and regulatory matters.

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

Revision to Prior Period Consolidated Financial Statements

The Company identified an error in the calculation of reserves for certain individual life products that impacted several line items within previously issued consolidated financial statements. Prior period amounts have been revised in the financial statements and related disclosures 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 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.

2.    SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS

Recent Accounting Pronouncements

Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASU") to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASU. ASU listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASU not listed below were assessed and determined to be either not applicable or not material.

Adoption of ASU 2016-01

Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities using a modified retrospective method. Adoption of this ASU impacted the Company’s accounting and presentation related to equity investments. The most significant impact is that the changes in fair value of equity securities previously classified as “available for sale” are to be reported in net income within “Other income” in the Consolidated Statements of Operations. Prior to this, the changes in fair value on equity securities classified as “available for sale” were reported in “Accumulated other comprehensive income”.

The impacts of this ASU on the Company’s Consolidated Financial Statements can be categorized as follows: (1) Changes to the presentation within the Consolidated Statements of Financial Position; (2) Cumulative-effect Adjustment Upon Adoption; and (3) Changes to Accounting Policies. Each of these components 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, 2017.

(1) Changes to the presentation within the Consolidated Statements of Financial Position

Because of the fundamental accounting changes as described in section "(3) Changes to Accounting Policies" below, the Company determined that changes to the presentation of certain balances in the investment section of the Company’s Consolidated Statements of Financial Position were also necessary to maintain clarity and logical presentation. The table below illustrates these changes by presenting the balances as previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and the reclassifications that were made, along with a footnote explanation of each reclassification.

ASSETS

Fixed maturities, trading is a new financial statement line item comprised of fixed maturities that are carried at fair value. Prior to the adoption of the standard, these fixed maturities were reported in “Trading account assets, at fair value”. Realized and unrealized gains and losses on these investments are reported in “Other income”, and interest and dividend income from these investments is reported in “Net investment income”.

Equity securities, at fairvalue is the new title of the financial statement line item formerly titled “Equity securities, available for sale, at fair value”. As a result of the adoption of the standard, equity securities previously reported in “Trading account assets, at fair value” were reclassified to “Equity securities, at fair value”. The retitled financial statement line is comprised of common stock and mutual fund shares, which are carried at fair value. Realized and unrealized gains and losses on these investments are reported in “Other income,” and dividend income is reported in “Net investment income” on the ex-dividend date. Prior to the adoption of the standard, for the equity investments reported in the financial statement line formerly titled “Equity securities, available for sale, at fair value” the associated net realized gains and losses were included in “Realized investment gains (losses), net” and the associated net unrealized gains and losses were included in “Accumulated other comprehensive income (loss)” (“AOCI”). In addition, with the adoption of the standard, the identification of OTTI for these investments is no longer needed as all of these investments are now measured at fair value with changes in fair value reported in earnings.

Other invested assets is the new title of the financial statement line formerly titled “Other long-term investments”. Investments previously reported in “Other long-term investments” were reclassified to “Other invested assets”. The retitled financial statement line consists of the Company’s non-coupon investments in Limited Partnerships and Limited Liability Companies ("LPs/LLCs") (other than operating joint ventures) and derivative assets. LPs/LLCs interests are accounted for using either the equity method of accounting, or at fair value with changes in fair value reported in “Other income”. Prior to the adoption of the standard, the Company applied the cost method of accounting for certain LPs/LLCs interests when its partnership interest was considered minor. The standard effectively eliminated the cost method of accounting for these equity investments. The Company’s income from investments in LPs/LLCs accounted for using the equity method, other than the Company’s investments in operating joint ventures, is included in “Net investment income”. The carrying value of these investments is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. In applying the equity method (including assessment for OTTI), the Company uses financial information provided by the investee, generally on a one to three month lag. For the investments reported at fair value with changes in fair value reported in current earnings, the associated realized and unrealized gains and losses are reported in “Other income”.

REVENUES AND BENEFITS AND EXPENSES

Other income includes realized and unrealized gains or losses from investments reported as “Fixed maturities, trading”, “Equity securities, at fair value,” and “Other invested assets” that are measured at fair value.

Other ASU adopted during the six months ended June 30, 2018.

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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	Adoption of the ASU did not have an impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force)	This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows.	January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 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).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, this ASU was issued following the enactment of the Tax Act of 2017. This ASU allows an entity to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Act of 2017. January 1, 2019 with early adoption permitted. The ASU should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act of 2017 is recognized. The Company early adopted the ASU effective January 1, 2018 and elected to apply the ASU in the period of adoption subsequent to recording the adoption impacts of ASU 2016-01 as described above. As a result, the Company reclassified stranded effects resulting from the Tax Act of 2017 by increasing accumulated other comprehensive income and decreasing retained earnings, each by $30.4 million. Stranded effects unrelated to the Tax Act of 2017 are generally released from accumulated other comprehensive income when an entire portfolio of the type of item related to the stranded effect is liquidated, sold or extinguished (i.e., portfolio approach).

ASU issued but not yet adopted as of June 30, 2018

Standard	Description	Effective date and method of adoption	Effect on the financial statements or other significant matters
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current 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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. However, prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an 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.
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) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	This ASU makes targeted changes to the existing hedge accounting model to better portray the economics of an entity’s risk management activities and to simplify the use of hedge accounting.	January 1, 2019 using the modified retrospective method (with early adoption permitted) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

As of June 30, 2018 and December 31, 2017, the gross unrealized losses on fixed maturity securities were composed of $91.4 million and $13.9 million, respectively, related to "1" highest quality or "2" high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $12.3 million and $4.9 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of June 30, 2018, the $29.2 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in the Company's corporate securities within the energy, finance and consumer non-cyclical sectors and in commercial mortgage-backed securities. As of December 31, 2017, the $16.2 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in commercial mortgage backed securities and in the Company's corporate securities within the energy and finance sectors. In accordance with its policy described in Note 2 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, the Company concluded that an adjustment to earnings for OTTI for these fixed maturity securities was not warranted at either June 30, 2018 or December 31, 2017. These conclusions were based on a detailed analysis of the underlying credit and cash flows on each security. Gross unrealized losses are primarily attributable to general credit spread widening, increases in interest rates and foreign currency exchange rate movements. As of June 30, 2018, 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:

For the six months endedJune 30, 2018 and 2017, the ineffective portion of derivatives accounted for using hedge accounting was de minimis 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 AOCI before taxes:

	(in thousands)
Balance, December 31, 2017	$	(17,678	)
Net deferred gains/(losses) on cash flow hedges from January 1 to June 30, 2018	16,418
Amounts reclassified into current period earnings	(7,761		)
Balance, June 30, 2018	$	(9,021	)

The changes in fair value of cash flow hedges are deferred in AOCI and are included in "Net unrealized investment gains (losses)" in the Unaudited Interim Consolidated Statements of Operations and Comprehensive Income (Loss); these amounts are then reclassified to earnings when the hedged item affects earnings. Using June 30, 2018 values, it is estimated that a pre-tax gain of $7 million will be reclassified from AOCI to earnings during the subsequent twelve months ending June 30,2019, offset by amounts pertaining to the hedged items.

As of June 30, 2018, 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.

Credit Derivatives

The company has no exposure from credit derivative positions where it has written credit protection as of June 30, 2018 and December 31, 2017.

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 $1 million and $2 million reported at fair value as a liability of $0.0 million and $0.1 million as of June 30, 2018 and December 31, 2017, respectively.

Credit Risk

The Company is exposed to credit-related losses in the event of non-performance by 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.

5.    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.

30

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

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, 2017.

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 at the value as of the beginning of the quarter in which the transfers occur for any such assets still held at the end of the quarter. Periodically there are transfers between Level 1 and Level 2 for assets held in the Company’s Separate account. The fair value of foreign common stock held in the Company's Separate account may reflect differences in market levels between the close of foreign trading markets and the close of U.S. trading markets for the respective day. Dependent on the existence of such a timing difference, the assets may move between Level 1 and Level 2. During both the three and six months ended June 30, 2018 and 2017, there were no transfers between Level 1 and Level 2.

(1) Conversely, the impact of a decrease in input would have the opposite impact on fair value as that presented in the table.

(2) Includes assets classified as fixed maturities, available-for-sale.

(3) Future policy benefits primarily represent general account liabilities for the living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.

(4) 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.

(5) 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 our estimates of rates that a market participant would use to value the living benefit contracts in both the accumulation and payout phases. 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 both funding agreements and living benefit contracts are insurance liabilities and are therefore senior to debt.

(6) 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.

(7) 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, 2018 and December 31, 2017, the minimum withdrawal rate assumption is 78% and the maximum withdrawal rate assumption may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.

(8) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 50to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

Interrelationships Between Unobservable Inputs– In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another, or multiple, inputs. For the discussion of the relationships between unobservable inputs as well as market factors that may affect the range of inputs used in the valuation of Level 3 assets and liabilities, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.

Changes in Level 3 Assets and Liabilities– The following tables describe changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter. For the three months ended June 30, 2018, $81 million of investments in collateralized loan obligations (“CLOs”) reported as “Asset-backed securities” were transferred from Level 3 to Level 2 as market activity, liquidity and overall observability of valuation inputs of CLOs have increased. 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, 2017.

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

(1) The information presented as of December 31, 2017, excludes certain hedge funds, private equity funds and other funds that were accounted for using the cost method and for which the fair value was measured at NAV per share (or its equivalent) as a practical expedient. The fair value and the carrying value of these cost method investments were $49 million and $41 million, respectively. Due to the adoption of ASU 2016-01 effective January 1, 2018, these assets are carried at fair value at each reporting date with changes in fair value reported in “Other income.” Therefore, as of June 30, 2018, these assets are excluded from this table but are reported in the fair value recurring measurement table.

(2) Carrying values presented herein differ from those in the Company’s Unaudited Interim Consolidated Statements of Financial Position because certain items within the respective financial statement captions are not considered financial instruments or are out of scope under authoritative guidance relating to disclosures of the fair value of financial instruments.

6.    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”. 

The Company's income tax provision, on a consolidated basis, amounted to an income tax benefit of $15.7 million, or (47.6)% of income from operations before income taxes in the first six months of 2018, compared to a benefit of $30.4 million, or (8.5)% of income from operations before income taxes in the first six months of 2017. The Company’s current effective tax rate differed from the U.S. statutory rate of 21% primarily due to non-taxable investment income and tax credits. The Company's prior 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. The Tax Cuts and Jobs Act of 2017 ("Tax Act of 2017") modified the methodology for determining the dividend received deduction and will likely reduce the tax benefit of non-taxable investment income in periods starting after December 31, 2017.

On December 22, 2017, the Tax Act of 2017 was enacted into U.S. law. As a result, the Company recognized a $20.2 million tax benefit in “Total income tax expense (benefit)” in the Company’s Consolidated Statements of Operations for the year ended December 31, 2017, which is inclusive of the impacts to prior periods due to the revision as discussed in Note 11. In accordance with SEC Staff Accounting Bulletin 118, the Company recorded the effects of the Tax Act of 2017 as reasonable estimates due to the need for further analysis of the provisions within the Tax Act of 2017 and collection, preparation and analysis of relevant data necessary to complete the accounting. The Company has not fully completed its accounting for the tax effects of the Tax Act of 2017. As the Company completes the collection, preparation and analysis of data relevant to the Tax Act of 2017, and interprets any additional guidance issued by the IRS, U.S. Department of the Treasury, or other standard-setting organizations, the Company may make adjustments to these provisional amounts. These adjustments may materially impact the Company’s provision for income taxes in the period in which the adjustments are made. During the first six months of 2018, the Company did not recognize additional refinements of our provisional estimates.

The cumulative financial statement impact related to the Tax Act of 2017 as of June 30, 2018 was unchanged from the balance as of December 31, 2017.

7.    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"), Dryden Arizona Reinsurance Term Company (“DART”), its parent company Prudential Insurance, as well as third parties, and participated in reinsurance with its affiliate Pruco Re through March 31, 2016 and its affiliate Universal Prudential Arizona Reinsurance Company ("UPARC") through June 30, 2017. The reinsurance agreements provide risk diversification and additional capacity for future growth, limit the maximum net loss potential, manage statutory capital, facilitate the Company's 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. Through June 30, 2017, the Company had an agreement with UPARC to reinsure a portion of the no-lapse guarantee provision on certain universal life products. See below for additional information on the change effective July 1, 2017 related to the recapture of the no-lapse guarantee risks that were previously reinsured to UPARC. 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”. For additional information related to the accounting for embedded derivatives, see Note 10 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.

Reinsurance amounts included in the Company’s Unaudited Interim Consolidated Statements of Financial Position as of June 30, 2018 and December 31, 2017 were as follows:

	June 30, 2018			December 31, 2017
	(in thousands)
Reinsurance recoverables (1)	$	31,935,722		$	32,521,264
Policy loans	(127,291		)	(124,843		)
Deferred policy acquisition costs	(7,166,225		)	(6,832,729		)
Deferred sales inducements	(601,927		)	(638,065		)

(1) Prior period amounts in the table above have been revised to correct previously reported numbers. These prior periods revisions have also been reflected in the Unaudited Interim Consolidated Financial Statements. See Note 11 for a more detailed description of the revision.

(2) “Other assets” includes $0.1 million of unaffiliated activity as of both June 30, 2018 and December 31, 2017.

(3) “Other liabilities” includes $51 million and $73 million of unaffiliated activity as of June 30, 2018 and December 31, 2017, respectively.

PALAC

Effective April 1, 2016, the Company entered into a reinsurance agreement with PALAC, to reinsure its variable annuity base contracts, along with the living benefit guarantees, excluding business reinsured externally and the PLNJ business, which was reinsured to Prudential Insurance. See Note 1 for additional information related to the Variable Annuities Recapture.

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.

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, excluding those policies that are subject to principles-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

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.

Prudential of Taiwan

On January 31, 2001, Pruco Life transferred all of its assets and liabilities associated with its Taiwan branch, including its Taiwan 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.

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. Effective July 1, 2017, the Company will reinsure a portion of the mortality risk directly to third-party reinsurers and retain all of the non-reinsured portion of the mortality risk.

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 with Prudential Insurance to reinsure its variable annuity base contracts, along with the living benefit guarantees. See Note 1 for additional information related to the Variable Annuities Recapture.

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.

UPARC

Through June 30, 2017, Pruco Life reinsured Universal Protector policies having no-lapse guarantees with effective dates through December 31, 2013 with UPARC. UPARC reinsured an amount equal to 27% of the net amount at risk related to the first $1 million in face amount plus 30% of the net amount at risk related to the face amount in excess of $1 million as well as 30% of the risk of uncollectible policy charges and fees associated with the no-lapse guarantee provision of these policies.

Effective July 1, 2017, Pruco Life recaptured the risks related to the no-lapse guarantees that were previously reinsured to UPARC and subsequently included these risks as part of the business ceded to GUL Re under the amended coinsurance agreement on that date. As part of the recapture, the Company received invested assets of $557 million as consideration from UPARC and unwound the associated reinsurance recoverable of $760 million. As a result, the Company recognized a loss of $203 million immediately.

Pruco Re

Through March 31, 2016, the Company, including its wholly-owned subsidiary PLNJ, entered into various automatic coinsurance agreements with Pruco Re to reinsure its living benefit guarantees sold on certain of its annuities. See Note 1 for additional information on the change effective April 1, 2016 related to the Variable Annuities Recapture.

Information regarding significant third party reinsurance arrangements is described below.

Union Hamilton

Between April 1, 2015 and December 31, 2016, the Company, excluding its subsidiaries, 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. During that time period, the Company ceded approximately $2.9 billion of new rider premiums to Union Hamilton under this agreement. 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, 2018, $3.1 billion of HDI v.3.0 account values are reinsured to Union Hamilton.

9.    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-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 $0.5 million for both the three months ended June 30, 2018 and 2017 and $0.7 million for both the six months ended June 30, 2018 and 2017. The expense charged to the Company for the deferred compensation program was $2 million for both the three months ended June 30, 2018 and 2017 and $4 million and $5 million for the six months ended June 30, 2018 and 2017, 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.

PRUCO LIFE INSURANCE COMPANY

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

The Company’s share of net expense for the pension plans was $6 million for both the three months ended June 30, 2018 and 2017, and $12 million and $13 million for the six months ended June 30, 2018 and 2017, 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.

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 for both the three months ended June 30, 2018 and 2017, and $5 million for both the six months ended June 30, 2018 and 2017.

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 $189 million and $160 million for the three months ended June 30, 2018 and 2017, respectively, and $363 million and $315 million for the six months ended June 30, 2018 and 2017, respectively.

Debt Agreements

The Company is authorized to borrow funds up to $2.2 billion from affiliates to meet its capital and other funding needs. The following table provides the breakout of the Company's short-term debt to affiliates as of June 30, 2018 and December 31, 2017.

Affiliate	Date Issued	Amount of Notes - June 30, 2018		Amount of Notes - December 31, 2017		Interest Rate		Date of Maturity
		(in thousands)
Prudential Funding, LLC	6/29/2018	$	1,727	$	0	2.04	%	7/6/2018

Through June 30, 2018, the Company did not pay any dividends. In December of 2017, the Company paid a dividend in the amount of $250 million to Prudential Insurance.

Reinsurance with Affiliates

As discussed in Note 7, the Company participates in reinsurance transactions with certain affiliates.

10.    COMMITMENTS AND CONTINGENT LIABILITIES

Commitments

The Company has made commitments to fund commercial loans. As of June 30, 2018 and December 31, 2017, the outstanding balances on these commitments were $41 million and $15 million, respectively. The Company also made commitments to purchase or fund investments, mostly private fixed maturities. As of June 30, 2018 and December 31, 2017, $191 million and $196 million, respectively, of these commitments were outstanding.

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 set 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’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.

61

PRUCO LIFE INSURANCE COMPANY

Notes to Unaudited Interim Consolidated Financial Statements—(Continued)

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, 2018, 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 litigation 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, 2017.

There are no material developments in previously reported matters disclosed as of December 31, 2017.

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.

11.    REVISION TO PRIOR YEAR INFORMATION

Revisions to 2017 Consolidated Financial Statements

The Company identified an error in the calculation of reserves for certain individual life products that impacted several line items within previously issued consolidated financial statements. Prior period amounts have been revised in the financial statements and related disclosures to correct this error as shown below. Management evaluated these adjustments and concluded they were not material to any previously reported quarterly or annual financial statements.

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 as of and for the three and six months ended June 30, 2017 and also for the year ended December 31, 2017, 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, 2018 and Annual Report on Form 10-K for the year ended December 31, 2018 will be revised.

The following are selected line items from the consolidated financial statements illustrating the effects of these revisions:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) addresses the consolidated financial condition of Pruco Life Insurance Company, or the “Company,” as of June 30, 2018, compared with December 31, 2017, and its consolidated results of operations for the three and six months ended June 30, 2018 and 2017. You should read the following analysis of our consolidated financial condition and results of operations in conjunction with the MD&A, the “Risk Factors” section, and the audited Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as well as the statements under “Forward-Looking Statements” and the Unaudited Interim Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Overview

The Company sells variable and fixed annuities, universal life insurance, variable life insurance and term life insurance primarily through affiliated and unaffiliated distributors in the United States.

In July 2017, the Company announced the formation of a joint venture with CT Corp to provide life insurance solutions in Indonesia. CT Corp controls one of Indonesia’s largest and most prominent business groups with primary areas of focus in the financial services, media, retail, property, lifestyle and entertainment sectors. The joint venture, in which the Company owns a 49% interest, is expected to take a multi-product and multi-channel distribution approach and will leverage CT Corp’s existing businesses and strategic partnerships to offer insurance products to customers. While this transaction is expected to provide long-term growth potential, it is not currently significant to the operating results of the Company.

Regulatory Developments

Fiduciary Rules

In March 2018, the Fifth Circuit Court of Appeals vacated the fiduciary rules adopted by the U.S. Department of Labor (“DOL”) in April 2016. The decision became effective in June 2018. We cannot predict how the decision will impact our businesses, including in view of other pending regulatory developments regarding enhanced standards of care.

In April 2018, the Securities and Exchange Commission (the “SEC”) proposed a package of rulemakings and interpretative guidance that would, among other things, require broker-dealers to act in the best interest of retail customers when recommending securities transactions or investment strategies to them. The proposals would also clarify the SEC’s views of the fiduciary duty that investment advisers owe to their clients. If enacted in their current form, we believe the primary impact of the proposals would be to sales of certain of our products and to our affiliated Prudential Advisors distribution system. Given the uncertainty of the ultimate outcome of these proposals, we cannot predict the timing of any final rules or interpretations or their expected effects on our businesses.

65

In July 2018, the New York Department of Financial Services issued an amendment to its suitability regulations which will impose a best-interest standard on the sale of annuity and life insurance products in New York. We cannot predict what impact the New York regulation will have on our business.

State Insurance Exam

In June 2018, the Arizona Department of Insurance and the New Jersey Department of Banking and Insurance, along with the insurance regulators of Connecticut and Indiana, completed their first global consolidated group-wide examination of Prudential Financial and its subsidiaries for the five-year period ended December 31, 2016 and had no reportable findings.

Risk-Based Capital

In June 2018, the Capital Adequacy Task Force of the National Association of Insurance Commissioners (the “NAIC”) approved revisions to the NAIC’s risk-based capital (“RBC”) framework in respect of the Tax Cuts and Jobs Act of 2017 (the “Tax Act of 2017”). The revisions will apply to our domestic life insurance companies’ RBC ratios as of December 31, 2018. For a discussion of the impact of the Tax Act of 2017 and these changes on our RBC ratios, see "Liquidity and Capital Resources—Capital".

For additional information on the potential impacts of regulation on the Company see “Business—Regulation” and “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017.

Impact of a Low Interest Rate Environment

As a global financial services company, market interest rates are a key driver of our results of operations and financial condition. Changes in interest rates can affect our results of operations and/or our financial condition in several ways, including favorable or adverse impacts to:

• investment-related activity, including: investment income returns, net interest margins, net investment spread

results, new money rates, mortgage loan prepayments and bond redemptions;

• insurance reserve levels, market experience true-ups and amortization of deferred policy acquisition costs (“DAC”)

• customer account values, including their impact on fee income;

• product offerings, design features, crediting rates and sales mix; and

• policyholder behavior, including surrender or withdrawal activity.

For more information on interest rate risks, see “Risk Factors—Market Risk” included in our Annual Report on Form 10-K for the year ended December 31, 2017.

Revenues and Expenses

The Company earns revenues principally from insurance premiums, mortality and expense fees, asset administration fees from insurance and investment products, and from net investment income on the investment of general account and other funds. The Company earns premiums primarily from the sale of individual life insurance and annuity products. The Company earns mortality and expense fees and asset administration fees primarily from the sale and servicing of universal life insurance and separate account products including variable life insurance and variable annuities. The Company’s operating expenses principally consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, reinsurance premiums, commissions and other costs of selling and servicing the various products sold and interest credited on general account liabilities.

Profitability

The Company’s profitability depends principally on its ability to price our insurance and annuity products at a level that enables us to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, our actuarial and policyholder behavior experience on insurance and annuity products, our ability to attract and retain customer assets, generate and maintain favorable investment results, and manage expenses.

See “Risk Factors” in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 for a discussion of risks that have materially affected and may affect in the future the Company’s business, results of operations or financial condition, or cause the Company’s actual results to differ materially from those expected or those expressed in any forward looking statements made by or on behalf of the Company.

Products

Individual Annuities

The Company offers a wide array of annuities, including variable annuities with (1) fixed interest rate allocation options, subject to a market value adjustment, that are registered with the SEC and (2) fixed-rate allocation options not subject to a market value adjustment and not registered with the SEC. The Company also offers fixed annuitization options during the payout phase of its variable annuities.

We offer certain variable annuities that provide our contractholders with tax-deferred asset accumulation together with a base death benefit, an optional enhanced death benefit and a suite of optional guaranteed living benefits (including versions with enhanced guaranteed minimum death benefits ("GMDB")) and annuitization options. The majority of our currently sold variable annuity contracts include an optional guaranteed living benefit which provides, among other features, the ability to make withdrawals based on the highest daily contract value plus a specified return, credited for a period of time. This contract value is a notional amount that forms the basis for determining periodic withdrawals for the life of the contractholder, and cannot be accessed as a lump-sum surrender value. Certain optional living benefits can also be purchased with a companion optional death benefit, also based on a highest daily contract value. Our results are impacted by the fee rates we assess on our products. Some of our historical in force products have fee tiers that decline throughout the life of the contract while our newer products generally have lower fee rates.

The Prudential Premier® Retirement Variable Annuity with Highest Daily Lifetime Income (“HDI”) offers lifetime income based on the highest daily account value plus a compounded deferral credit. HDI v.3.0 is the most current version of our “highest daily” guaranteed living benefits. An optional enhanced death benefit called Legacy Protection Plus is available only at time of purchase and not in combination with any other benefit options. Under the Legacy Protection Plus benefit, we maintain a separate death benefit amount based on the contract holder's purchase payments subject to annual roll-up increases at a preset rate until certain events occur.

The Prudential Defined Income (“PDI”) Variable Annuity complements other variable annuity products we offer with the highest daily lifetime income benefit. PDI provides for guaranteed lifetime withdrawal payments, but restricts contractholder investment to a single bond fund sub-account within the separate accounts. PDI includes a living benefit guarantee which provides for a specified lifetime income withdrawal rate applied to purchase payments paid, subject to daily roll-up increases until lifetime withdrawals commence, but does not have the highest daily feature.

We also offer variable annuities without guaranteed living benefits. The Prudential Premier® Investment Variable Annuity ("PPI") offers tax-deferred asset accumulation, annuitization options and an optional death benefit that guarantees the contractholder’s beneficiary a return of total purchase payments made to the contract, adjusted for any partial withdrawals, upon death.

Excluding our PDI product, the majority of our variable annuities generally provide our contractholders with the opportunity to allocate purchase payments to sub-accounts that invest in underlying proprietary and/or non-proprietary mutual funds, frequently under asset allocation programs. Certain products also allow or require allocation to fixed-rate accounts that are invested in the general account and are credited with interest at rates we determine, subject to certain minimums. We also offer fixed annuities that provide a guarantee of principal and interest credited at rates we determine, subject to certain contractual minimums. For certain products, we have the ability to reset the crediting rates at our discretion subject to certain contract terms establishing guaranteed minimum interest crediting rates. Certain allocations made in the fixed-rate accounts of our variable annuities and certain fixed annuities impose a market value adjustment if the invested amount is not held to maturity.

In addition, most contracts also guarantee the contractholder's beneficiary a return of total purchase payments made to the contract, adjusted for any partial withdrawals, upon death. Certain in force contracts include guaranteed benefits which are not currently offered with new sales, such as annuitization benefits based on a guaranteed notional amount and benefits payable at specified dates after the accumulation period.

The Company's in force business includes both variable and fixed annuities that may include optional living benefits guarantees (e.g., guaranteed minimum income benefits (“GMIB”), guaranteed minimum accumulation benefits (“GMAB”), guaranteed minimum withdrawal benefits (“GMWB”), and guaranteed minimum income and withdrawal benefits (“GMIWB”)), and/or GMDB.

The reserves for GMDB and GMIB are calculated based on best estimates applying our actuarial and capital markets return assumptions in accordance with an insurance fulfillment accounting framework whereby a liability is established over time representing the portion of fees collected that is expected to be used to satisfy the obligation to pay benefits in future periods.

67

In contrast, certain of our guaranteed living benefits (e.g., GMAB, GMWB and GMIWB) are accounted for in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") as embedded derivatives and reported using a fair value accounting framework. These benefit features are carried at fair value based on estimates of assumptions a market participant would use in valuing these embedded derivatives and the change in fair value during each reporting period is recorded within “Realized investment gains (losses), net”.

As mentioned below, in addition to our asset transfer feature, we manage certain risks associated with our variable annuity products through affiliated and unaffiliated reinsurance agreements. Through March 31, 2016, we reinsured the majority of our variable annuity living benefit guarantees to an affiliated reinsurance company, Pruco Re. The living benefits hedging program was primarily executed within Pruco Re to manage capital markets risk associated with the reinsured living benefit guarantees. 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 the variable annuity base contracts, along with the living benefit guarantees, to PALAC, excluding PLNJ business which was reinsured to Prudential Insurance. These reinsurance agreements cover new and in force business and exclude business reinsured externally. The product risks related to the business reinsured to PALAC are being managed in PALAC and the product risks related to the business reinsured to Prudential Insurance are being managed in Prudential Insurance. In addition, the living benefits hedging program related to the reinsured living benefit guarantees is being managed within PALAC or Prudential Insurance, as applicable.

Term Life Insurance

The Company offers a variety of term life insurance products, which represent 67% of our net individual life insurance in force at June 30, 2018, that provide coverage for a specified time period. Most term products include a conversion feature that allows the policyholder to convert the policy into permanent life insurance coverage. The Company also offers term life insurance that provides for a return of premium if the insured is alive at the end of the level premium period. There continues to be significant demand for term life insurance protection.

Variable Life Insurance

The Company offers a number of individual variable life insurance products, which represent 18% of our net individual life insurance in force at June 30, 2018, that give the policyholder the flexibility to change both the death benefit and premium payments, and provide the potential to earn returns based on an underlying investment portfolio that the policyholder selects. The policyholder generally can make deposits for investments in a fixed-rate option which is part of our general account or in separate account investment options consisting of equity and fixed income funds. Funds invested in the fixed-rate option provide a guarantee of principal and are credited with interest at rates that we determine, subject to certain contractual minimums. In the separate accounts, the policyholder bears the fund performance risk. The Company also offers a variable life product that has an optional flexible guarantee against lapse where policyholders can select the guarantee period. While variable life insurance continues to be an important product, marketplace demand continues to favor term and universal life insurance. A meaningful portion of the Company's individual life insurance profits, however, is associated with our large in force block of variable life insurance policies.

Universal Life Insurance

The Company offers universal life insurance products that feature flexible premiums and a crediting rate that we determine, subject to certain contractual minimums. Guaranteed universal life products, which represent 12% of our net individual life insurance in force at June 30, 2018, provide a guarantee of death benefits to remain in force when a policy would otherwise lapse due to insufficient cash value. The Company also offers other universal life insurance products, which represent 3% of our net individual life insurance in force at June 30, 2018. These include products that allow the policyholders to allocate all or a portion of their account balance into an index account. The index account provides interest or an interest component linked to, but not an investment in, S&P 500 index performance over the following year, subject to certain participation rates and contractual minimums and maximums. Mortality and expense margins and net interest spread impact profits from universal life insurance.

Accounting Policies & Pronouncements

Application of Critical Accounting Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Management reviews estimates and assumptions used in the preparation of financial statements on an ongoing basis. If management determines that modifications in assumptions and estimates are appropriate given current facts and circumstances, the Company’s results of operations and financial position as reported in the Unaudited Interim Consolidated Financial Statements could change significantly.

Management believes the accounting policies relating to the following areas are most dependent on the application of estimates and assumptions and require management’s most difficult, subjective, or complex judgments:

• DAC and other costs, including deferred sales inducements (“DSI”);

• Policyholder liabilities;

• Valuation of investments, including derivatives, and the recognition of other-than-temporary impairments ("OTTI");

• Reinsurance recoverables;

• Taxes on income; and

• Reserves for contingencies, including reserves for losses in connection with unresolved legal matters.

DAC and Other Costs

DAC and other costs associated with the variable and universal life policies and the variable and fixed annuity contracts are generally amortized over the expected lives of these policies in proportion to total gross profits. Total gross profits include both actual gross profits and estimates of gross profits for future periods. The quarterly adjustments for market performance reflect the impact of changes to our estimate of total gross profits to reflect actual fund performance and market conditions. A significant portion of gross profits for our variable annuity contracts and, to a lesser degree, our variable life policies are dependent upon the total rate of return on assets held in separate account investment options. This rate of return influences the fees we earn, costs we incur associated with the guaranteed minimum death and guaranteed minimum income benefit features related to our variable annuity contracts, as well as other sources of profit. Returns that are higher than our expectations for a given period produce higher than expected account balances, which increase the future fees we expect to earn and decrease the future costs we expect to incur associated with the guaranteed minimum death and guaranteed minimum income benefit features related to our variable annuity contracts. The opposite occurs when returns are lower than our expectations. The changes in future expected gross profits are used to recognize a cumulative adjustment to all prior periods’ amortization.

The weighted average rate of return assumptions used in developing estimated gross profits consider many factors specific to each business, including asset durations, asset allocations and other factors. With regard to equity market assumptions, the near-term future rate of return assumption used in evaluating DAC and other costs for our domestic variable annuity and variable life insurance products is generally updated each quarter and is derived using a reversion to the mean approach, a common industry practice. Under this approach, we consider historical equity returns and adjust projected equity returns over an initial future period of five years (the “near-term”) so that equity returns converge to the long-term expected rate of return. If the near-term projected future rate of return is greater than our near-term maximum future rate of return of 15.0%, we use our maximum future rate of return. As of June 30, 2018, our variable annuities and variable life insurance businesses assume an 8.0% long-term equity expected rate of return and a 4.1% near-term mean reversion equity expected rate of return.

With regard to interest rate assumptions, we generally update the future interest rates used to project fixed income returns annually and in any quarter when interest rates vary significantly from these assumptions. As a result of our 2018 annual reviews and update of assumptions and other refinements, we kept our long-term expectation of the 10-year U.S. Treasury rate unchanged from last year and continue to grade to 3.75% over ten years. This market performance related adjustment to our estimate of total gross profits results in a cumulative adjustment to prior amortization, reflecting the application of the new required rate of amortization to all prior periods’ gross profits.

Adoption of New Accounting Pronouncements

Changes in Financial Position

June 30, 2018 versus December 31, 2017

Total assets decreased $2.6 billion, from $172.4 billion at December 31, 2017 to $169.8 billion at June 30, 2018. Significant components were:

• Separate account assets decreased $2.0 billion, primarily driven by policy charges, net outflows and unfavorable market performance.

• Reinsurance recoverables decreased $0.6 billion, primarily driven by the annuity reinsured living benefit liabilities resulting from a decrease in future expected benefit payments driven by rising rates and credit spread widening, partially offset by an increase in universal life recoverables driven by business growth.

Total liabilities decreased $2.5 billion, from $169.6 billion at December 31, 2017 to $167.1 billion at June 30, 2018. Significant components were:

• Separate account liabilities decreased $2.0 billion, corresponding to the decrease in separate account assets described above.

• Future policy benefits decreased $1.4 billion, primarily due to the impact of rising rates and credit spread widening, as discussed above.

• Policyholders’ account balances increased $1.1 billion, primarily driven by universal life business growth.

Total equity decreased $0.1 billion, from $2.8 billion at December 31, 2017 to $2.7 billion at June 30, 2018, primarily driven by accumulated other comprehensive income which decreased by $135 million driven by unrealized losses from higher interest rates.

Results of Operations

Income (loss) from Operations before Income Taxes

2018 to 2017 Three Months Comparison

Income (loss) from operations before income taxes decreased $308 million from $331 million in the second quarter of 2017 to $23 million in the second quarter of 2018. This was primarily driven by a decrease in realized investment gains of $314 million driven by the absence of gains on the embedded derivative with UPARC in the prior year quarter, as well as increases in general, administrative, and other expenses of $27 million driven by unfavorable impact from deferred reinsurance activity in the annuity business during the quarter. This was partially offset by $31 million of favorable comparative net impacts from our annual reviews and update of assumptions and other refinements, mainly driven by favorable impacts related to mortality and investment assumption updates in the individual life business and the $7 million favorable impact of a revision to the financial statements as disclosed in Note 11.

2018 to 2017 Six Months Comparison

Income (loss) from operations before income taxes decreased $324 million from $357 million for the first six months of 2017 to $33 million for the first six months of 2018. This was primarily driven by a decrease in realized investment gains of $330 million driven by the absence of gains on the embedded derivative with UPARC in the prior year quarter, as well as increases in general, administrative, and other expenses of $31 million driven by unfavorable impact from deferred reinsurance activity in the annuity business during the year. This was partially offset by $31 million of favorable comparative net impacts from our annual reviews and update of assumptions and other refinements, mainly driven by favorable impacts related to mortality and investment assumption updates in the individual life business and the $3 million favorable impact of a revision to the financial statements as disclosed in Note 11.

70

Revenues, Benefits and Expenses

2018 to 2017 Three Months Comparison

Revenues decreased $39 million from $287 million in the second quarter of 2017 to $248 million in the second quarter of 2018. Excluding the impact of our annual reviews and update of assumptions and other refinements and revision, as discussed above, revenues decreased by $346 million primarily driven by the decrease of $314 million in total realized investment gains (losses), net primarily driven by the absence of realized investment gains on the embedded derivative with UPARC, as discussed above. Further, there was a decrease of $22 million in policy charges and fees reflecting the increase of cost of reinsurance charges.

Benefits and expenses increased $269 million from income of $44 million in the second quarter of 2017 to an expense of $225 million in the second quarter of 2018. Excluding the impact of our annual reviews and update of assumptions and other refinements and revision, as discussed above, benefits and expenses decreased by $7 million, primarily driven by a $27 million decrease in policyholder's benefits primarily reflecting lower reserves as a result of the increase in the cost of reinsurance for GMDB recoverable as well as a $9 million decrease in amortization of deferred policy acquisition costs primarily driven by unfavorable mortality experience relative to expectations and favorable impacts from strong equity market performance. This was partially offset by a $27 million increase in general, administrative, and other expenses primarily driven by deferred reinsurance activity in the annuities business.

2018 to 2017 Six Months Comparison

Revenues decreased $61 million from $498 million for the first six months of 2017 to $437 million for the first six months of 2018. Excluding the impact of our annual reviews and update of assumptions and other refinements and revision, as discussed above, revenues decreased $368 million, primarily driven by the decrease of $330 million in total realized investment gains (losses), net primarily driven by the absence of realized investment gains on the embedded derivative with UPARC, as discussed above. Further, there was a decrease of $21 million in policy charges and fees reflecting the increase of cost of reinsurance charges.

Benefits and expenses increased $263 million from $141 million in the second quarter of 2017 to $404 million in the second quarter of 2018. Excluding the impact of our annual reviews and update of assumptions and other refinements and revision, as discussed above, benefits and expenses decreased $13 million primarily driven by a $44 million decrease in policyholder's benefits primarily reflecting lower reserves as a result of the increase in the cost of reinsurance for GMDB recoverable. This is partially offset by a $31 million increase in general, administrative, and other expenses primarily driven by deferred reinsurance activity in the annuities business.

Variable Annuity Risks and Risk Mitigants

The following is a summary of: (i) certain risks associated with Individual Annuities’ products; (ii) certain strategies in mitigating those risks, including any updates to those strategies since the previous year end; and (iii) the related financial results. For a more detailed description of these items and their related accounting treatment, refer to the complete descriptions provided in our Annual Report on Form 10-K for the year ended December 31, 2017.

The primary risk exposures of our variable annuity contracts relate to actual deviations from, or changes to, the assumptions used in the original pricing of these products, including capital markets assumptions such as equity market returns, interest rates and market volatility, along with actuarial assumptions such as contractholder mortality, the timing and amount of annuitization and withdrawals, and contract lapses. For these risk exposures, achievement of our expected earnings and profitability is subject to the risk that actual experience will differ from the assumptions used in the original pricing of these products. We currently manage our exposure to certain risks driven by capital markets fluctuations primarily through a combination of product design features, an Asset Liability Management ("ALM") Strategy and External Reinsurance.

71

Product Design Features

A portion of the variable annuity contracts that we offer include an asset transfer feature. This feature is implemented at the contract level, and transfers assets between certain variable investment sub-accounts selected by the annuity contractholder and, depending on the benefit feature, a fixed-rate account in the general account or a bond fund sub-account within the separate account. The objective of the asset transfer feature is to help reduce our exposure to equity market risk and market volatility. The asset transfer feature associated with currently-sold highest daily benefit products uses a designated bond fund sub-account within the separate account. The transfers are based on a static mathematical formula used with the particular benefit which considers a number of factors, including, but not limited to, the impact of investment performance on the contractholder’s total account value. Other product design features we utilize include, among others, asset allocation restrictions, minimum issuance age requirements and certain limitations on the amount of contractholder deposits, as well as a required minimum allocation to our general account for certain of our products. We have also introduced products that diversify our risk profile and have incorporated provisions in product design allowing frequent revisions of key pricing elements. In addition, there is diversity in our fee arrangements, as certain fees are primarily based on the benefit guarantee amount, the contractholder account value and/or premiums, which helps preserve certain revenue streams when market fluctuations cause account values to decline.

External Reinsurance

As of June 30, 2018, $3.1 billion of HDI v3.0 account values are reinsured to Union Hamilton Reinsurance Ltd., an external counterparty, pursuant to a quota share agreement that covered approximately 50% of new HDI v3.0 business issued between April 1, 2015 and December 31, 2016. HDI v3.0 is the current version of our “highest daily” living benefits guarantee that is available with our Prudential Premier® Retirement Variable Annuity. New sales of HDI v3.0 optional living benefits subsequent to December 31, 2016 are not covered by this external reinsurance agreement.

Asset Liability Management Strategy (including fixed income instruments and derivatives)

The current ALM strategy conducted within PALAC and Prudential Insurance utilizes a combination of both traditional fixed income instruments and derivatives to defray potential claims associated with our variable annuity living benefit guarantees. The economic liability we manage with this ALM strategy consists of expected living benefit claims under less severe market conditions, which are managed using a traditional ALM strategy through the accumulation of fixed income and derivative instruments, and potential living benefit claims resulting from more severe market conditions, which are hedged using derivative instruments. For the portion of our ALM strategy executed with derivatives, PALAC and Prudential Insurance enter into a range of exchange-traded, cleared, and over-the-counter (“OTC”) equity and interest rate derivatives, including, but not limited to: equity and treasury futures; total return and interest rate swaps; and options including equity options, swaptions, and floors and caps. Since the ALM strategy is conducted in PALAC and Prudential Insurance, the results of the strategy do not directly impact the Company's results of operations or financial condition.

Capital Hedge Program

During 2017, we commenced a capital hedge program within PALAC to further hedge equity market impacts. The program is intended to protect a portion of the overall capital position of the variable annuities business against its exposure to the equity markets. The capital hedge program is conducted using equity derivatives which include equity call and put options, total return swaps and futures contracts. Since the capital hedge program is conducted in PALAC, the results of the strategy do not directly impact the Company's results of operations or financial condition.

Liquidity and Capital Resources

This section supplements and should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” included in our Annual Report on Form 10-K for the year ended December 31, 2017.

72

Overview

Liquidity refers to the ability to generate sufficient cash resources to meet the payment obligations of the Company. Capital refers to the long-term financial resources available to support the operations of our businesses, fund business growth, and provide a cushion to withstand adverse circumstances. Our ability to generate and maintain sufficient liquidity and capital depends on the profitability of our businesses, general economic conditions, our ability to borrow from affiliates and our access to the capital markets through affiliates as described herein.

Effective and prudent liquidity and capital management is a priority across the organization. Management monitors the liquidity of Prudential Financial, Prudential Insurance and the Company on a daily basis and projects borrowing and capital needs over a multi-year time horizon through our periodic planning process. We believe that cash flows from available sources of funds are sufficient to satisfy the current liquidity requirements of Prudential Insurance, Prudential Financial and the Company, including under reasonably foreseeable stress scenarios. Prudential Financial has a capital management framework in place that governs the allocation of capital and approval of capital uses. Prudential Financial and the Company also employ a “Capital Protection Framework” to ensure the availability of capital resources to maintain adequate capitalization and competitive risk-based capital ("RBC") ratios under various stress scenarios.

Prudential Financial is a Designated Financial Company under Dodd-Frank. As a Designated Financial Company, Prudential Financial is subject to supervision and examination by the Federal Reserve Bank of Boston and to stricter prudential regulatory standards, which include or will include requirements and limitations (many of which are the subject of ongoing rule-making) relating to capital, leverage, liquidity, stress-testing, overall risk management, resolution and recovery plans, credit exposure reporting, early remediation, management interlocks and credit concentration. They may also include standards regarding enhanced public disclosure, short-term debt limits and other related subjects. In addition, the Financial Stability Board has identified Prudential Financial as a global systemically important insurer ("G-SII"). For information on these regulatory initiatives and their potential impact on us, see "Business—Regulation” and “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2017.

Through March 31, 2016, the Company reinsured the majority of its variable annuity living benefit guarantees to an affiliated company, Pruco Re, in order to facilitate the capital markets hedging program for these living benefit guarantees. Effective April 1, 2016, the Company recaptured the risks related to its variable annuity living benefit guarantees that were previously reinsured to Pruco Re and reinsured the variable annuity base contracts, along with the living benefit guarantees, to PALAC, excluding the PLNJ business which was reinsured to Prudential Insurance.

Capital

Our capital management framework is primarily based on statutory RBC measures. The RBC ratio is a primary measure of the capital adequacy of the Company. RBC is calculated based on statutory financial statements and risk formulas consistent with the practices of the NAIC. RBC considers, among other things, risks related to the type and quality of the invested assets, insurance-related risks associated with an insurer’s products and liabilities, interest rate risks and general business risks. RBC ratio calculations are intended to assist insurance regulators in measuring an insurer’s solvency and ability to pay future claims. The reporting of RBC measures is not intended for the purpose of ranking any insurance company or for use in connection with any marketing, advertising or promotional activities, but is available to the public. The RBC ratio is an annual calculation; however, as of June 30, 2018 we estimate that the Company’s RBC ratio exceeds the minimum level required by applicable insurance regulations.

In June 2018, the Capital Adequacy Task Force of the NAIC approved revisions to the NAIC RBC framework as a result of the adoption of the Tax Act of 2017 and the corresponding reduction of the corporate tax rate from 35% to 21%. The revisions will apply to the calculation of our domestic insurance life insurance companies’ RBC ratios as of December 31, 2018. The reduction of the corporate tax rate under the Tax Act of 2017 has the effect of increasing certain RBC factors, resulting in an overall decrease in insurers’ RBC ratios. The Company expects to have the necessary resources to maintain its “AA” ratings targets under this proposed RBC framework.

The regulatory capital level of the Company can be materially impacted by interest rate and equity market fluctuations, changes in the values of derivatives, the level of impairments recorded, credit quality migration of the investment portfolio, and business growth, among other items. In addition, the reinsurance of business or the recapture of business subject to reinsurance arrangements could negatively impact regulatory capital levels. The Company’s regulatory capital level is also affected by statutory accounting rules, which are subject to change by each applicable insurance regulator.

73

Capital Protection Framework

Prudential Financial and the Company employ a "Capital Protection Framework" (the "Framework”) to ensure that sufficient capital resources are available to maintain adequate capitalization and competitive RBC ratios and solvency margins under various stress scenarios. The Framework incorporates the potential impacts from market related stresses, including equity markets, real estate, interest rates, and credit losses.

The Framework accommodates periodic volatility within ranges that are deemed acceptable, while also providing for potential sources of capital, including on-balance sheet capital, derivatives, and contingent sources of capital. We believe we currently have access to sufficient resources, either directly, or indirectly through Prudential Financial, to maintain adequate capitalization and a competitive RBC ratio under a range of potential stress scenarios.

Liquidity

Our liquidity is managed to ensure stable, reliable and cost-effective sources of cash flows to meet all of our obligations. Liquidity is provided by a variety of sources, as described more fully below, including portfolios of liquid assets. Our investment portfolios are integral to the overall liquidity of the Company. We use a projection process for cash flows from operations to ensure sufficient liquidity to meet projected cash outflows, including claims. The impact of Prudential Funding, LLC’s, or Prudential Funding, a wholly-owned subsidiary of Prudential Insurance, financing capacity on liquidity (as described below) is considered in the internal liquidity measures of the Company.

Liquidity is measured against internally-developed benchmarks that take into account the characteristics of both the asset portfolio and the liabilities that they support. We consider attributes of the various categories of liquid assets (for example, type of asset and credit quality) in calculating internal liquidity measures to evaluate our liquidity under various stress scenarios, including company-specific and market-wide events. We continue to believe that cash generated by ongoing operations and the liquidity profile of our assets provide sufficient liquidity under reasonably foreseeable stress scenarios.

Cash Flow

The principal sources of the Company’s liquidity are premiums and certain annuity considerations, investment and fee income, investment maturities and sales as well as internal borrowings. The principal uses of that liquidity include benefits, claims, and payments to policyholders and contractholders in connection with surrenders, withdrawals and net policy loan activity. Other uses of liquidity may include commissions, general and administrative expenses, purchases of investments, the payment of dividends to the parent company, hedging and reinsurance activity and payments in connection with financing activities.

Liquid Assets

Liquid assets include cash and cash equivalents, short-term investments, fixed maturities that are not designated as held-to-maturity and public equity securities. As of June 30, 2018 and December 31, 2017 the Company had liquid assets of $5,368 million and $5,517 million, respectively. The portion of liquid assets comprised of cash and cash equivalents and short-term investments was $73 million and $214 million as of June 30, 2018 and December 31, 2017, respectively. As of June 30, 2018, $4,823 million, or 92%, of the fixed maturity investments in Company general account portfolios were rated high or highest quality based on NAIC or equivalent rating.

Affiliated captive reinsurance companies are used to finance the portion of the statutory reserves required to be held under Regulation XXX and Guideline AXXX that is considered non-economic. The financing arrangements involve term and universal life business we reinsure to our affiliated captive reinsurers. The surplus notes issued by those affiliated captives are treated as capital for statutory purposes. These surplus notes are subordinated to policyholder obligations, and the payment of principal on the surplus notes can be made with prior insurance regulatory approval.

74

Our affiliated captive reinsurance companies have entered into agreements with external counterparties providing for the issuance of surplus notes in return for the receipt of credit-linked notes ("Credit-Linked Note Structures"). Under the agreements, the affiliated captive receives in exchange for the surplus notes one or more credit-linked notes issued by a special-purpose affiliate of the Company with an aggregate principal amount equal to the surplus notes outstanding. The affiliated captive holds the credit-linked notes as assets supporting Regulation XXX or Guideline AXXX non-economic reserves, as applicable. As of June 30, 2018, our affiliated captive reinsurance companies had Credit-Linked Note Structures with an aggregate issuance capacity of $13,700 million, of which $10,619 million was outstanding, as compared to an aggregate issuance capacity of $11,100 million, of which $9,487 million was outstanding, as of December 31, 2017. For more information on the Credit-Linked Note Structures, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Financing Activities” in our Annual Report on Form 10-K for the year ended December 31, 2017.

As of June 30, 2018, our affiliated captive reinsurance companies also had outstanding an aggregate of $2.4 billion of debt issued for the purpose of financing Regulation XXX and Guideline AXXX non-economic reserves, of which approximately $0.6 billion relates to Regulation XXX reserves and approximately $1.8 billion relates to Guideline AXXX reserves, all of which was issued by Prudential Financial. In addition, as of June 30, 2018, for purposes of financing Guideline AXXX reserves, our affiliated captives had outstanding approximately $4.0 billion of surplus notes that were issued to Prudential Financial in exchange for promissory notes of affiliates guaranteed by Prudential Financial.

The NAIC’s actuarial guideline known as “AG 48” requires our affiliated captive reinsurance companies to hold cash and rated securities in greater amounts than previously held to support economic reserves for certain of our term and universal life policies reinsured to a captive. The total additional asset requirement from the inception of AG 48 through December 31, 2017, was approximately $1.8 billion, which was funded using a combination of existing assets and newly purchased assets sourced from affiliated financing. We believe our affiliated captive reinsurance companies have sufficient internal and affiliated resources to satisfy the additional asset requirement through 2018.

The Company adopted principles-based reserving for its guaranteed universal life products and introduced updated versions of these products in 2017. The updated products are expected to support the principles-based statutory reserve level without the need for financing through captive reinsurance. The Company is continuing to assess the impact of principles-based reserving on projected statutory reserve levels and product pricing for its remaining portfolio of individual life product offerings.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of fluctuations in the value of financial instruments as a result of absolute or relative changes in interest rates, foreign currency exchange rates, equity prices or commodity prices. To varying degrees, our products and services, and the investment activities supporting them, generate exposure to market risk. The market risk incurred, and our strategies for managing this risk, vary by product. As of June 30, 2018, there have been no material changes in our economic exposure to market risk from December 31, 2017, a description of which may be found in our Annual Report on Form 10-K for the year ended December 31, 2017, Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” filed with the SEC. See Item 1A, “Risk Factors” included in the Annual Report on Form 10-K for the year ended December 31, 2017, for a discussion of how difficult conditions in the financial markets and the economy generally may materially adversely affect our business and results of our operations.

Item 4.  Controls and Procedures

In order to ensure that the information we must disclose in our filings with the SEC is recorded, processed, summarized, and reported on a timely basis, the Company’s management, including our Chief Executive Officer and Chief Financial Officer, have reviewed and evaluated the effectiveness of our disclosure controls and procedures, as defined in Securities Exchange Act of 1934, as amended (“Exchange Act”) Rule 13a-15(e), as of June 30, 2018. Based on such evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2018, our disclosure controls and procedures were effective. No change in our internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), occurred during the quarter ended June 30, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

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 and other 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.

Variable Annuities Recapture

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 coinsurance and modified coinsurance agreements. 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".

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, 2017.

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 and related amortization; amortization of deferred sales inducements; 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 and regulatory matters.

Revision to Prior Period Consolidated Financial Statements

The Company identified an error in the calculation of reserves for certain individual life products that impacted several line items within previously issued consolidated financial statements. Prior period amounts have been revised in the financial statements and related disclosures 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 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.

Significant Accounting Policies and Pronouncements

SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS

Recent Accounting Pronouncements

Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASU") to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASU. ASU listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASU not listed below were assessed and determined to be either not applicable or not material.

Adoption of ASU 2016-01

Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities using a modified retrospective method. Adoption of this ASU impacted the Company’s accounting and presentation related to equity investments. The most significant impact is that the changes in fair value of equity securities previously classified as “available for sale” are to be reported in net income within “Other income” in the Consolidated Statements of Operations. Prior to this, the changes in fair value on equity securities classified as “available for sale” were reported in “Accumulated other comprehensive income”.

The impacts of this ASU on the Company’s Consolidated Financial Statements can be categorized as follows: (1) Changes to the presentation within the Consolidated Statements of Financial Position; (2) Cumulative-effect Adjustment Upon Adoption; and (3) Changes to Accounting Policies. Each of these components 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, 2017.

(1) Changes to the presentation within the Consolidated Statements of Financial Position

Because of the fundamental accounting changes as described in section "(3) Changes to Accounting Policies" below, the Company determined that changes to the presentation of certain balances in the investment section of the Company’s Consolidated Statements of Financial Position were also necessary to maintain clarity and logical presentation. The table below illustrates these changes by presenting the balances as previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and the reclassifications that were made, along with a footnote explanation of each reclassification.

(2) Eliminated the line item “Trading account assets, at fair value” and reclassified each component to another line item.

(3) Retitled “Other long-term investments” to “Other invested assets”.

(2) Cumulative-effect Adjustment Upon Adoption

The provisions of ASU 2016-01 require that the Company apply the amendments through a cumulative-effect adjustment to the Consolidated Statements of Financial Position as of the beginning of the fiscal year of adoption. The following table illustrates the impact on the Company’s Consolidated Statement of Financial Position as a result of recording this cumulative-effect adjustment on January 1, 2018.

(3) Changes to Accounting Policies

This section summarizes the changes in our accounting policies resulting from the adoption of ASU 2016-01 as well as an update to the components of the financial statement line items impacted by the Company’s Consolidated Statements of Financial Position presentation changes described above.

ASSETS

Fixed maturities, trading is a new financial statement line item comprised of fixed maturities that are carried at fair value. Prior to the adoption of the standard, these fixed maturities were reported in “Trading account assets, at fair value”. Realized and unrealized gains and losses on these investments are reported in “Other income”, and interest and dividend income from these investments is reported in “Net investment income”.

Equity securities, at fairvalue is the new title of the financial statement line item formerly titled “Equity securities, available for sale, at fair value”. As a result of the adoption of the standard, equity securities previously reported in “Trading account assets, at fair value” were reclassified to “Equity securities, at fair value”. The retitled financial statement line is comprised of common stock and mutual fund shares, which are carried at fair value. Realized and unrealized gains and losses on these investments are reported in “Other income,” and dividend income is reported in “Net investment income” on the ex-dividend date. Prior to the adoption of the standard, for the equity investments reported in the financial statement line formerly titled “Equity securities, available for sale, at fair value” the associated net realized gains and losses were included in “Realized investment gains (losses), net” and the associated net unrealized gains and losses were included in “Accumulated other comprehensive income (loss)” (“AOCI”). In addition, with the adoption of the standard, the identification of OTTI for these investments is no longer needed as all of these investments are now measured at fair value with changes in fair value reported in earnings.

Other invested assets is the new title of the financial statement line formerly titled “Other long-term investments”. Investments previously reported in “Other long-term investments” were reclassified to “Other invested assets”. The retitled financial statement line consists of the Company’s non-coupon investments in Limited Partnerships and Limited Liability Companies ("LPs/LLCs") (other than operating joint ventures) and derivative assets. LPs/LLCs interests are accounted for using either the equity method of accounting, or at fair value with changes in fair value reported in “Other income”. Prior to the adoption of the standard, the Company applied the cost method of accounting for certain LPs/LLCs interests when its partnership interest was considered minor. The standard effectively eliminated the cost method of accounting for these equity investments. The Company’s income from investments in LPs/LLCs accounted for using the equity method, other than the Company’s investments in operating joint ventures, is included in “Net investment income”. The carrying value of these investments is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. In applying the equity method (including assessment for OTTI), the Company uses financial information provided by the investee, generally on a one to three month lag. For the investments reported at fair value with changes in fair value reported in current earnings, the associated realized and unrealized gains and losses are reported in “Other income”.

REVENUES AND BENEFITS AND EXPENSES

Other income includes realized and unrealized gains or losses from investments reported as “Fixed maturities, trading”, “Equity securities, at fair value,” and “Other invested assets” that are measured at fair value.

Other ASU adopted during the six months ended June 30, 2018.

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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	Adoption of the ASU did not have an impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force)	This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows.	January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 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).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, this ASU was issued following the enactment of the Tax Act of 2017. This ASU allows an entity to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Act of 2017. January 1, 2019 with early adoption permitted. The ASU should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act of 2017 is recognized. The Company early adopted the ASU effective January 1, 2018 and elected to apply the ASU in the period of adoption subsequent to recording the adoption impacts of ASU 2016-01 as described above. As a result, the Company reclassified stranded effects resulting from the Tax Act of 2017 by increasing accumulated other comprehensive income and decreasing retained earnings, each by $30.4 million. Stranded effects unrelated to the Tax Act of 2017 are generally released from accumulated other comprehensive income when an entire portfolio of the type of item related to the stranded effect is liquidated, sold or extinguished (i.e., portfolio approach).

ASU issued but not yet adopted as of June 30, 2018

Standard	Description	Effective date and method of adoption	Effect on the financial statements or other significant matters
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current 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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. However, prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an 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.
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) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	This ASU makes targeted changes to the existing hedge accounting model to better portray the economics of an entity’s risk management activities and to simplify the use of hedge accounting.	January 1, 2019 using the modified retrospective method (with early adoption permitted) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	The Company does not expect the adoption of the ASU to have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

As of June 30, 2018 and December 31, 2017, the gross unrealized losses on fixed maturity securities were composed of $91.4 million and $13.9 million, respectively, related to "1" highest quality or "2" high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $12.3 million and $4.9 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of June 30, 2018, the $29.2 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in the Company's corporate securities within the energy, finance and consumer non-cyclical sectors and in commercial mortgage-backed securities. As of December 31, 2017, the $16.2 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in commercial mortgage backed securities and in the Company's corporate securities within the energy and finance sectors. In accordance with its policy described in Note 2 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, the Company concluded that an adjustment to earnings for OTTI for these fixed maturity securities was not warranted at either June 30, 2018 or December 31, 2017. These conclusions were based on a detailed analysis of the underlying credit and cash flows on each security. Gross unrealized losses are primarily attributable to general credit spread widening, increases in interest rates and foreign currency exchange rate movements. As of June 30, 2018, 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:

(1) Amounts deferred in AOCI.

For the six months endedJune 30, 2018 and 2017, the ineffective portion of derivatives accounted for using hedge accounting was de minimis 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 AOCI before taxes:

	(in thousands)
Balance, December 31, 2017	$	(17,678	)
Net deferred gains/(losses) on cash flow hedges from January 1 to June 30, 2018	16,418
Amounts reclassified into current period earnings	(7,761		)
Balance, June 30, 2018	$	(9,021	)

The changes in fair value of cash flow hedges are deferred in AOCI and are included in "Net unrealized investment gains (losses)" in the Unaudited Interim Consolidated Statements of Operations and Comprehensive Income (Loss); these amounts are then reclassified to earnings when the hedged item affects earnings. Using June 30, 2018 values, it is estimated that a pre-tax gain of $7 million will be reclassified from AOCI to earnings during the subsequent twelve months ending June 30,2019, offset by amounts pertaining to the hedged items.

As of June 30, 2018, 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.

Credit Derivatives

The company has no exposure from credit derivative positions where it has written credit protection as of June 30, 2018 and December 31, 2017.

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 $1 million and $2 million reported at fair value as a liability of $0.0 million and $0.1 million as of June 30, 2018 and December 31, 2017, respectively.

Credit Risk

The Company is exposed to credit-related losses in the event of non-performance by 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 of Assets and Liabilities

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, 2017.

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.

(1) “Netting” amounts represent cash collateral of $37.7 million and $45.4 million as of June 30, 2018 and December 31, 2017, respectively, and the impact of offsetting asset and liability positions held with the same counterparty, subject to master netting arrangements.

(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, 2018 and December 31, 2017, the fair values of such investments were $66.2 million and $0.7 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 net asset value per share ("NAV") (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). As of June 30, 2018 and December 31, 2017, the fair values of such investments were $4,176 million and $4,113 million, respectively.

(6) As of June 30, 2018, the net embedded derivative liability position of $3,917 million includes $901 million of embedded derivatives in an asset position and $4,818 million of embedded derivatives in a liability position. As of December 31, 2017, the net embedded derivative liability position of $5,453 million includes $823 million of embedded derivatives in an asset position and $6,276 million of embedded derivatives in a liability position.

(7) Prior period amounts have been reclassified to conform to current period presentation. See Note 2 for details.

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 at the value as of the beginning of the quarter in which the transfers occur for any such assets still held at the end of the quarter. Periodically there are transfers between Level 1 and Level 2 for assets held in the Company’s Separate account. The fair value of foreign common stock held in the Company's Separate account may reflect differences in market levels between the close of foreign trading markets and the close of U.S. trading markets for the respective day. Dependent on the existence of such a timing difference, the assets may move between Level 1 and Level 2. During both the three and six months ended June 30, 2018 and 2017, 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.

(1) Conversely, the impact of a decrease in input would have the opposite impact on fair value as that presented in the table.

(2) Includes assets classified as fixed maturities, available-for-sale.

(3) Future policy benefits primarily represent general account liabilities for the living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.

(4) 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.

(5) 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 our estimates of rates that a market participant would use to value the living benefit contracts in both the accumulation and payout phases. 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 both funding agreements and living benefit contracts are insurance liabilities and are therefore senior to debt.

(6) 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.

(7) 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, 2018 and December 31, 2017, the minimum withdrawal rate assumption is 78% and the maximum withdrawal rate assumption may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.

(8) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 50to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

Interrelationships Between Unobservable Inputs– In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another, or multiple, inputs. For the discussion of the relationships between unobservable inputs as well as market factors that may affect the range of inputs used in the valuation of Level 3 assets and liabilities, see Note 9 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.

Changes in Level 3 Assets and Liabilities– The following tables describe changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter. For the three months ended June 30, 2018, $81 million of investments in collateralized loan obligations (“CLOs”) reported as “Asset-backed securities” were transferred from Level 3 to Level 2 as market activity, liquidity and overall observability of valuation inputs of CLOs have increased. 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, 2017.

(1) The information presented as of December 31, 2017, excludes certain hedge funds, private equity funds and other funds that were accounted for using the cost method and for which the fair value was measured at NAV per share (or its equivalent) as a practical expedient. The fair value and the carrying value of these cost method investments were $49 million and $41 million, respectively. Due to the adoption of ASU 2016-01 effective January 1, 2018, these assets are carried at fair value at each reporting date with changes in fair value reported in “Other income.” Therefore, as of June 30, 2018, these assets are excluded from this table but are reported in the fair value recurring measurement table.

(2) Carrying values presented herein differ from those in the Company’s Unaudited Interim Consolidated Statements of Financial Position because certain items within the respective financial statement captions are not considered financial instruments or are out of scope under authoritative guidance relating to disclosures of the fair value of financial instruments.

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

The Company uses a full year projected effective tax rate approach to calculate year-to-date taxes. In addition, certain items impacting total income tax expense are recorded in the periods in which they occur. The projected effective tax rate is the ratio of projected “Total income tax expense” divided by projected “Income from operations before income taxes”. 

The Company's income tax provision, on a consolidated basis, amounted to an income tax benefit of $15.7 million, or (47.6)% of income from operations before income taxes in the first six months of 2018, compared to a benefit of $30.4 million, or (8.5)% of income from operations before income taxes in the first six months of 2017. The Company’s current effective tax rate differed from the U.S. statutory rate of 21% primarily due to non-taxable investment income and tax credits. The Company's prior 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. The Tax Cuts and Jobs Act of 2017 ("Tax Act of 2017") modified the methodology for determining the dividend received deduction and will likely reduce the tax benefit of non-taxable investment income in periods starting after December 31, 2017.

On December 22, 2017, the Tax Act of 2017 was enacted into U.S. law. As a result, the Company recognized a $20.2 million tax benefit in “Total income tax expense (benefit)” in the Company’s Consolidated Statements of Operations for the year ended December 31, 2017, which is inclusive of the impacts to prior periods due to the revision as discussed in Note 11. In accordance with SEC Staff Accounting Bulletin 118, the Company recorded the effects of the Tax Act of 2017 as reasonable estimates due to the need for further analysis of the provisions within the Tax Act of 2017 and collection, preparation and analysis of relevant data necessary to complete the accounting. The Company has not fully completed its accounting for the tax effects of the Tax Act of 2017. As the Company completes the collection, preparation and analysis of data relevant to the Tax Act of 2017, and interprets any additional guidance issued by the IRS, U.S. Department of the Treasury, or other standard-setting organizations, the Company may make adjustments to these provisional amounts. These adjustments may materially impact the Company’s provision for income taxes in the period in which the adjustments are made. During the first six months of 2018, the Company did not recognize additional refinements of our provisional estimates.

The cumulative financial statement impact related to the Tax Act of 2017 as of June 30, 2018 was unchanged from the balance as of December 31, 2017.

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"), Dryden Arizona Reinsurance Term Company (“DART”), its parent company Prudential Insurance, as well as third parties, and participated in reinsurance with its affiliate Pruco Re through March 31, 2016 and its affiliate Universal Prudential Arizona Reinsurance Company ("UPARC") through June 30, 2017. The reinsurance agreements provide risk diversification and additional capacity for future growth, limit the maximum net loss potential, manage statutory capital, facilitate the Company's 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. Through June 30, 2017, the Company had an agreement with UPARC to reinsure a portion of the no-lapse guarantee provision on certain universal life products. See below for additional information on the change effective July 1, 2017 related to the recapture of the no-lapse guarantee risks that were previously reinsured to UPARC. 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”. For additional information related to the accounting for embedded derivatives, see Note 10 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.

Reinsurance amounts included in the Company’s Unaudited Interim Consolidated Statements of Financial Position as of June 30, 2018 and December 31, 2017 were as follows:

PALAC

Effective April 1, 2016, the Company entered into a reinsurance agreement with PALAC, to reinsure its variable annuity base contracts, along with the living benefit guarantees, excluding business reinsured externally and the PLNJ business, which was reinsured to Prudential Insurance. See Note 1 for additional information related to the Variable Annuities Recapture.

PURC

Prudential of Taiwan

On January 31, 2001, Pruco Life transferred all of its assets and liabilities associated with its Taiwan branch, including its Taiwan 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.

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 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.

UPARC

Through June 30, 2017, Pruco Life reinsured Universal Protector policies having no-lapse guarantees with effective dates through December 31, 2013 with UPARC. UPARC reinsured an amount equal to 27% of the net amount at risk related to the first $1 million in face amount plus 30% of the net amount at risk related to the face amount in excess of $1 million as well as 30% of the risk of uncollectible policy charges and fees associated with the no-lapse guarantee provision of these policies.

Effective July 1, 2017, Pruco Life recaptured the risks related to the no-lapse guarantees that were previously reinsured to UPARC and subsequently included these risks as part of the business ceded to GUL Re under the amended coinsurance agreement on that date. As part of the recapture, the Company received invested assets of $557 million as consideration from UPARC and unwound the associated reinsurance recoverable of $760 million. As a result, the Company recognized a loss of $203 million immediately.

Pruco Re

Through March 31, 2016, the Company, including its wholly-owned subsidiary PLNJ, entered into various automatic coinsurance agreements with Pruco Re to reinsure its living benefit guarantees sold on certain of its annuities. See Note 1 for additional information on the change effective April 1, 2016 related to the Variable Annuities Recapture.

Information regarding significant third party reinsurance arrangements is described below.

Union Hamilton

Between April 1, 2015 and December 31, 2016, the Company, excluding its subsidiaries, 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.

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-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 $0.5 million for both the three months ended June 30, 2018 and 2017 and $0.7 million for both the six months ended June 30, 2018 and 2017. The expense charged to the Company for the deferred compensation program was $2 million for both the three months ended June 30, 2018 and 2017 and $4 million and $5 million for the six months ended June 30, 2018 and 2017, 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, 2018 and 2017, and $12 million and $13 million for the six months ended June 30, 2018 and 2017, 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, 2018 and 2017, and $15 million and $14 million for the six months ended June 30, 2018 and 2017, 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 $3 million for both the three months ended June 30, 2018 and 2017, and $5 million for both the six months ended June 30, 2018 and 2017.

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 $189 million and $160 million for the three months ended June 30, 2018 and 2017, respectively, and $363 million and $315 million for the six months ended June 30, 2018 and 2017, 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 $19 million and $15 million for the three months ended June 30, 2018 and 2017, respectively and $37 million and $32 million for the six months ended June 30, 2018 and 2017, 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 $3,783 million at June 30, 2018 and $3,688 million at December 31, 2017. Fees related to these COLI policies were $11 million for both the three months ended June 30, 2018 and 2017 and $23 million for both the six months ended June 30, 2018 and 2017. The Company retains the majority of the mortality risk associated with these COLI policies up to $3.5 million per policy.

Affiliated Investment Management Expenses

In accordance with an agreement with PGIM, Inc.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

COMMITMENTS AND CONTINGENT LIABILITIES

Commitments

The Company has made commitments to fund commercial loans. As of June 30, 2018 and December 31, 2017, the outstanding balances on these commitments were $41 million and $15 million, respectively. The Company also made commitments to purchase or fund investments, mostly private fixed maturities. As of June 30, 2018 and December 31, 2017, $191 million and $196 million, respectively, of these commitments were outstanding.

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 set 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’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. The Company estimates that as of June 30, 2018, 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 litigation 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, 2017.

There are no material developments in previously reported matters disclosed as of December 31, 2017.

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.

Prior Period Adjustment [Abstract]

Revision to Prior Year Information

REVISION TO PRIOR YEAR INFORMATION

Revisions to 2017 Consolidated Financial Statements

The Company identified an error in the calculation of reserves for certain individual life products that impacted several line items within previously issued consolidated financial statements. Prior period amounts have been revised in the financial statements and related disclosures to correct this error as shown below. Management evaluated these adjustments and concluded they were not material to any previously reported quarterly or annual financial statements.

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 as of and for the three and six months ended June 30, 2017 and also for the year ended December 31, 2017, 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, 2018 and Annual Report on Form 10-K for the year ended December 31, 2018 will be revised.

The following are selected line items from the consolidated financial statements illustrating the effects of these revisions:

Significant Accounting Policies and Pronouncements (Policies)

6 Months Ended

Jun. 30, 2018

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, 2017.

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 and related amortization; amortization of deferred sales inducements; 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 and regulatory matters.

Reclassifications

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Investment and Investment Related Lines

Fixed maturities, trading is a new financial statement line item comprised of fixed maturities that are carried at fair value. Prior to the adoption of the standard, these fixed maturities were reported in “Trading account assets, at fair value”. Realized and unrealized gains and losses on these investments are reported in “Other income”, and interest and dividend income from these investments is reported in “Net investment income”.

Equity securities, at fairvalue is the new title of the financial statement line item formerly titled “Equity securities, available for sale, at fair value”. As a result of the adoption of the standard, equity securities previously reported in “Trading account assets, at fair value” were reclassified to “Equity securities, at fair value”. The retitled financial statement line is comprised of common stock and mutual fund shares, which are carried at fair value. Realized and unrealized gains and losses on these investments are reported in “Other income,” and dividend income is reported in “Net investment income” on the ex-dividend date. Prior to the adoption of the standard, for the equity investments reported in the financial statement line formerly titled “Equity securities, available for sale, at fair value” the associated net realized gains and losses were included in “Realized investment gains (losses), net” and the associated net unrealized gains and losses were included in “Accumulated other comprehensive income (loss)” (“AOCI”). In addition, with the adoption of the standard, the identification of OTTI for these investments is no longer needed as all of these investments are now measured at fair value with changes in fair value reported in earnings.

Other invested assets is the new title of the financial statement line formerly titled “Other long-term investments”. Investments previously reported in “Other long-term investments” were reclassified to “Other invested assets”. The retitled financial statement line consists of the Company’s non-coupon investments in Limited Partnerships and Limited Liability Companies ("LPs/LLCs") (other than operating joint ventures) and derivative assets. LPs/LLCs interests are accounted for using either the equity method of accounting, or at fair value with changes in fair value reported in “Other income”. Prior to the adoption of the standard, the Company applied the cost method of accounting for certain LPs/LLCs interests when its partnership interest was considered minor. The standard effectively eliminated the cost method of accounting for these equity investments. The Company’s income from investments in LPs/LLCs accounted for using the equity method, other than the Company’s investments in operating joint ventures, is included in “Net investment income”. The carrying value of these investments is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. In applying the equity method (including assessment for OTTI), the Company uses financial information provided by the investee, generally on a one to three month lag. For the investments reported at fair value with changes in fair value reported in current earnings, the associated realized and unrealized gains and losses are reported in “Other income”.

Other income

Other income includes realized and unrealized gains or losses from investments reported as “Fixed maturities, trading”, “Equity securities, at fair value,” and “Other invested assets” that are measured at fair value.

Adoption of New Accounting Pronouncements

Other ASU adopted during the six months ended June 30, 2018.

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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	Adoption of the ASU did not have an impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force)	This ASU addresses diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard provides clarity on the treatment of eight specifically defined types of cash inflows and outflows.	January 1, 2018 using the retrospective method (with early adoption permitted provided that all amendments are adopted in the same period).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.
ASU 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).	Adoption of the ASU did not have a significant impact on the Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, this ASU was issued following the enactment of the Tax Act of 2017. This ASU allows an entity to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Act of 2017. January 1, 2019 with early adoption permitted. The ASU should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act of 2017 is recognized. The Company early adopted the ASU effective January 1, 2018 and elected to apply the ASU in the period of adoption subsequent to recording the adoption impacts of ASU 2016-01 as described above. As a result, the Company reclassified stranded effects resulting from the Tax Act of 2017 by increasing accumulated other comprehensive income and decreasing retained earnings, each by $30.4 million. Stranded effects unrelated to the Tax Act of 2017 are generally released from accumulated other comprehensive income when an entire portfolio of the type of item related to the stranded effect is liquidated, sold or extinguished (i.e., portfolio approach).

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.

Adoption of ASU 2016-01

Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities using a modified retrospective method. Adoption of this ASU impacted the Company’s accounting and presentation related to equity investments. The most significant impact is that the changes in fair value of equity securities previously classified as “available for sale” are to be reported in net income within “Other income” in the Consolidated Statements of Operations. Prior to this, the changes in fair value on equity securities classified as “available for sale” were reported in “Accumulated other comprehensive income”.

The impacts of this ASU on the Company’s Consolidated Financial Statements can be categorized as follows: (1) Changes to the presentation within the Consolidated Statements of Financial Position; (2) Cumulative-effect Adjustment Upon Adoption; and (3) Changes to Accounting Policies. Each of these components 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, 2017.

(1) Changes to the presentation within the Consolidated Statements of Financial Position

Because of the fundamental accounting changes as described in section "(3) Changes to Accounting Policies" below, the Company determined that changes to the presentation of certain balances in the investment section of the Company’s Consolidated Statements of Financial Position were also necessary to maintain clarity and logical presentation. The table below illustrates these changes by presenting the balances as previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and the reclassifications that were made, along with a footnote explanation of each reclassification.

(3) Retitled “Other long-term investments” to “Other invested assets”.

(2) Cumulative-effect Adjustment Upon Adoption

The provisions of ASU 2016-01 require that the Company apply the amendments through a cumulative-effect adjustment to the Consolidated Statements of Financial Position as of the beginning of the fiscal year of adoption. The following table illustrates the impact on the Company’s Consolidated Statement of Financial Position as a result of recording this cumulative-effect adjustment on January 1, 2018.

Future Adoption Of New Accounting Pronouncements

ASU issued but not yet adopted as of June 30, 2018

Standard	Description	Effective date and method of adoption	Effect on the financial statements or other significant matters
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This ASU provides a new current expected credit loss model to account for credit losses on certain financial assets and off-balance sheet exposures (e.g., loans held for investment, debt securities held to maturity, reinsurance receivables, net investments in leases and loan commitments). The model requires an entity to estimate lifetime credit losses related to such financial assets and exposures based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard also modifies the current 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 which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. However, prospective application is required for purchased credit deteriorated assets previously accounted for under ASU 310-30 and for debt securities for which an 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.
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) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	This ASU makes targeted changes to the existing hedge accounting model to better portray the economics of an entity’s risk management activities and to simplify the use of hedge accounting.	January 1, 2019 using the modified retrospective method (with early adoption permitted) which will include a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption.	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.

(1) “Netting” amounts represent cash collateral of $37.7 million and $45.4 million as of June 30, 2018 and December 31, 2017, respectively, and the impact of offsetting asset and liability positions held with the same counterparty, subject to master netting arrangements.

(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, 2018 and December 31, 2017, the fair values of such investments were $66.2 million and $0.7 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 net asset value per share ("NAV") (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). As of June 30, 2018 and December 31, 2017, the fair values of such investments were $4,176 million and $4,113 million, respectively.

(6) As of June 30, 2018, the net embedded derivative liability position of $3,917 million includes $901 million of embedded derivatives in an asset position and $4,818 million of embedded derivatives in a liability position. As of December 31, 2017, the net embedded derivative liability position of $5,453 million includes $823 million of embedded derivatives in an asset position and $6,276 million of embedded derivatives in a liability position.

(7) Prior period amounts have been reclassified to conform to current period presentation. See Note 2 for details.

Fair Value Inputs, Assets and Liabilities, Quantitative Information

(1) Conversely, the impact of a decrease in input would have the opposite impact on fair value as that presented in the table.

(2) Includes assets classified as fixed maturities, available-for-sale.

(3) Future policy benefits primarily represent general account liabilities for the living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.

(4) 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.

(5) 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 our estimates of rates that a market participant would use to value the living benefit contracts in both the accumulation and payout phases. 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 both funding agreements and living benefit contracts are insurance liabilities and are therefore senior to debt.

(6) 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.

(7) 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, 2018 and December 31, 2017, the minimum withdrawal rate assumption is 78% and the maximum withdrawal rate assumption may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.

(8) Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 50to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation

The following tables describe changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods. When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter. For the three months ended June 30, 2018, $81 million of investments in collateralized loan obligations (“CLOs”) reported as “Asset-backed securities” were transferred from Level 3 to Level 2 as market activity, liquidity and overall observability of valuation inputs of CLOs have increased. 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, 2017.

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. All transfers are generally reported at the value as of the beginning of the quarter in which transfers occur for any such assets still held at the end of the quarter. For the three months ended June 30, 2018, $81 million of investments in collateralized loan obligations (“CLOs”) reported as “Asset-backed securities” were transferred from Level 3 to Level 2 as market activity, liquidity and overall observability of valuation inputs of CLOs have increased. 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, 2017.

(1) The information presented as of December 31, 2017, excludes certain hedge funds, private equity funds and other funds that were accounted for using the cost method and for which the fair value was measured at NAV per share (or its equivalent) as a practical expedient. The fair value and the carrying value of these cost method investments were $49 million and $41 million, respectively. Due to the adoption of ASU 2016-01 effective January 1, 2018, these assets are carried at fair value at each reporting date with changes in fair value reported in “Other income.” Therefore, as of June 30, 2018, these assets are excluded from this table but are reported in the fair value recurring measurement table.

(2) Carrying values presented herein differ from those in the Company’s Unaudited Interim Consolidated Statements of Financial Position because certain items within the respective financial statement captions are not considered financial instruments or are out of scope under authoritative guidance relating to disclosures of the fair value of financial instruments.
