Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Basis of Presentation Protective Life Insurance Company (the “Company”), a stock life insurance company, was founded in 1907. The Company is a wholly owned subsidiary of Protective Life Corporation (“PLC”), an insurance holding company. On February 1, 2015, PLC became a wholly owned subsidiary of The Dai-ichi Life Insurance Company, Limited, a kabushiki kaisha organized under the laws of Japan (now known as Dai-ichi Life Holdings, Inc., “Dai-ichi Life”), when DL Investment (Delaware), Inc. a wholly owned subsidiary of Dai-ichi Life, merged with and into PLC (the “Merger”). Prior to February 1, 2015, and for the periods reported as “predecessor,” PLC’s stock was publicly traded on the New York Stock Exchange. Subsequent to the Merger date, PLC and the Company remain as SEC registrants within the United States. The Company markets individual life insurance, credit life and disability insurance, guaranteed investment contracts, guaranteed funding agreements, fixed and variable annuities, and extended service contracts throughout the United States. The Company also maintains a separate segment devoted to the acquisition of insurance policies from other companies. PLC is a holding company with subsidiaries that provide financial services through the production, distribution, and administration of insurance and investment products. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Such accounting principles differ from statutory reporting practices used by insurance companies in reporting to state regulatory authorities (see also Note 22, Statutory Reporting Practices and Other Regulatory Matters ). The operating results of companies in the insurance industry have historically been subject to significant fluctuations due to changing competition, economic conditions, interest rates, investment performance, insurance ratings, claims, persistency, and other factors. Entities Included The consolidated financial statements include the accounts of Protective Life Insurance Company and its affiliate companies in which the Company holds a majority voting or economic interest. Intercompany balances and transactions have been eliminated.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs ("DAC") and related amortization periods, goodwill recoverability, value of business acquired ("VOBA"), investment and certain derivatives fair values, other-than-temporary impairments, future policy benefits, pension and other postretirement benefits, provisions for income taxes, reserves for contingent liabilities, reinsurance risk transfer assessments, and reserves for losses in connection with unresolved legal matters. Significant Accounting Policies Valuation of Investment Securities The Company determines the appropriate classification of investment securities at the time of purchase and periodically re-evaluates such designations. Investment securities are classified as either trading, available-for-sale, or held-to-maturity securities. Investment securities classified as trading are recorded at fair value with changes in fair value recorded in realized gains (losses). Investment securities purchased for long term investment purposes are classified as available-for-sale and are recorded at fair value with changes in unrealized gains and losses, net of taxes, reported as a component of other comprehensive income (loss). Investment securities are classified as held-to-maturity when the Company has the intent and ability to hold the securities to maturity and are reported at amortized cost. Interest income on available-for-sale and held-to-maturity securities includes the amortization of premiums and accretion of discounts and are recorded in investment income. The fair value of fixed maturity, short-term, and equity securities is determined by management after considering one of three primary sources of information: third party pricing services, non-binding independent broker quotations, or pricing matrices. Security pricing is applied using a "waterfall" approach whereby publicly available prices are first sought from third party pricing services, the remaining unpriced securities are submitted to independent brokers for non-binding prices, or lastly, securities are priced using a pricing matrix. Typical inputs used by these three pricing methods include, but are not limited to: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. Based on the typical trading volumes and the lack of quoted market prices for available-for-sale and trading fixed maturities, third party pricing services derive the majority of security prices from observable market inputs such as recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information as outlined above. If there are no recent reported trades, the third party pricing services and brokers may use matrix or model processes to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Certain securities are priced via independent non-binding broker quotations, which are considered to have no significant unobservable inputs. When using non-binding independent broker quotations, the Company obtains one quote per security, typically from the broker from which the Company purchased the security. A pricing matrix is used to price securities for which the Company is unable to obtain or effectively rely on either a price from a third party service or an independent broker quotation. Included in the pricing of other asset-backed securities, collateralized mortgage obligations ("CMOs"), and mortgage-backed securities ("MBS") are estimates of the rate of future prepayments of principal and underlying collateral support over the remaining life of the securities. Such estimates are derived based on the characteristics of the underlying structure and rates of prepayments previously experienced at the interest rate levels projected for the underlying collateral. The basis for the cost of securities sold was determined at the Committee on Uniform Securities Identification Procedures ("CUSIP") level on a first in first out basis. The committee supplies a unique nine-character identification, called a CUSIP number, for each class of security approved for trading in the U.S., to facilitate clearing and settlement. These numbers are used when any buy and sell orders are recorded. Each quarter the Company reviews investments with unrealized losses and tests for other-than-temporary impairments. The Company analyzes various factors to determine if any specific other-than-temporary asset impairments exist. These include, but are not limited to: 1) actions taken by rating agencies, 2) default by the issuer, 3) the significance of the decline, 4) an assessment of the Company's intent to sell the security (including a more likely than not assessment of whether the Company will be required to sell the security) before recovering the security's amortized cost, 5) the duration of the decline, 6) an economic analysis of the issuer's industry, and 7) the financial strength, liquidity, and recoverability of the issuer. Management performs a security by security review each quarter in evaluating the need for any other-than-temporary impairments. Although no set formula is used in this process, the investment performance, collateral position, and continued viability of the issuer are significant measures considered, and in some cases, an analysis regarding the Company's expectations for recovery of the security's entire amortized cost basis through the receipt of future cash flows is performed. Once a determination has been made that a specific other-than-temporary impairment exists, the security's basis is adjusted and an other-than-temporary impairment is recognized. Equity securities that are other-than-temporarily impaired are written down to fair value with a realized loss recognized in earnings. Other-than-temporary impairments to debt securities that the Company does not intend to sell and does not expect to be required to sell before recovering the security's amortized cost are written down to discounted expected future cash flows ("post impairment cost") and credit losses are recorded in earnings. The difference between the securities' discounted expected future cash flows and the fair value of the securities on the impairment date is recognized in other comprehensive income (loss) as a non-credit portion impairment. When calculating the post impairment cost for residential mortgage-backed securities ("RMBS"), commercial mortgage-backed securities ("CMBS"), and other asset-backed securities (collectively referred to as asset-backed securities or "ABS"), the Company considers all known market data related to cash flows to estimate future cash flows. When calculating the post impairment cost for corporate debt securities, the Company considers all contractual cash flows to estimate expected future cash flows. To calculate the post impairment cost, the expected future cash flows are discounted at the original purchase yield. Debt securities that the Company intends to sell or expects to be required to sell before recovery are written down to fair value with the change recognized in earnings. Cash Cash includes all demand deposits reduced by the amount of outstanding checks and drafts. As a result of the Company’s cash management system, checks issued from a particular bank but not yet presented for payment may create negative book cash balances with the bank at certain reporting dates. Such negative balances are included in other liabilities and were $132.7 million as of December 31, 2017 (Successor Company) and $79.2 million as of December 31, 2016 (Successor Company), respectively. The Company has deposits with certain financial institutions which exceed federally insured limits. The Company has reviewed the creditworthiness of these financial institutions and believes there is minimal risk of a material loss. Deferred Policy Acquisition Costs The incremental direct costs associated with successfully acquired insurance policies, are deferred to the extent such costs are deemed recoverable from future profits. Such costs include commissions and other costs of acquiring traditional life and health insurance, credit insurance, universal life insurance, and investment products. DAC are subject to recoverability testing at the end of each accounting period. Traditional life and health insurance acquisition costs are amortized over the premium-payment period of the related policies in proportion to the ratio of annual premium income to the present value of the total anticipated premium income. Credit insurance acquisition costs are being amortized in proportion to earned premium. Acquisition costs for universal life and investment products are amortized over the lives of the policies in relation to the present value of estimated gross profits before amortization. The Company makes certain assumptions regarding the mortality, persistency, expenses, and interest rates (equal to the rate used to compute liabilities for future policy benefits, currently 1.0% to 7.8% ) the Company expects to experience in future periods when determining the present value of estimated gross profits. These assumptions are best estimates and are periodically updated whenever actual experience and/or expectations for the future change from that assumed. Additionally, these costs have been adjusted by an amount equal to the amortization that would have been recorded if unrealized gains or losses on investments associated with our universal life and investment products had been realized. Acquisition costs for stable value contracts are amortized over the term of the contracts using the effective yield method. Value of Businesses Acquired In conjunction with the Merger and the acquisition of insurance policies or investment contracts, a portion of the purchase price is allocated to the right to receive future gross profits from cash flows and earnings of associated insurance policies and investment contracts. This intangible asset, called VOBA, is based on the actuarially estimated present value of future cash flows from associated insurance policies and investment contracts acquired. The estimated present value of future cash flows used in the calculation of the VOBA is based on certain assumptions, including mortality, persistency, expenses, and interest rates that the Company expects to experience in future years. The Company amortizes VOBA in proportion to gross premiums for traditional life products, or estimated gross margins ("EGMs") for participating traditional life products within the MONY Life Insurance Company ("MONY") block. For interest sensitive products, the Company uses various amortization bases including expected gross profits ("EGPs"), revenues, or insurance in-force. VOBA is subject to annual recoverability testing. Intangible Assets Intangible assets with definite lives are amortized over the estimated useful life of the asset and reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Amortizable intangible assets primarily consist of distribution relationships, trade names, technology, and software. Intangible assets with indefinite lives, primarily insurance licenses, are not amortized, but are reviewed for impairment on an annual basis or whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Software is generally amortized over a three year useful life. Intangible assets recognized by the Company included the following (excluding goodwill): Successor Company As of December 31, Estimated 2017 2016 Useful Life (Dollars In Thousands) (In Years) Distribution relationships $ 402,975 $ 428,499 14-22 Trade names 85,340 92,049 13-17 Technology 107,343 121,253 7-14 Other 35,258 13,547 Total intangible assets subject to amortization 630,916 655,348 Insurance licenses 32,000 32,000 Indefinite Total intangible assets $ 662,916 $ 687,348 Identified intangible assets were valued using the excess earnings method, relief from royalty method or cost approach, as appropriate. Amortizable intangible assets will be amortized straight line over their assigned useful lives. The following is a schedule of future estimated aggregate amortization expense: Year Amount (Dollars In Thousands) 2018 $ 55,932 2019 52,819 2020 49,818 2021 48,026 2022 35,329 Property and Equipment In conjunction with the Merger, property and equipment was recorded at fair value as of the Merger date and will be depreciated from this basis in future periods based on the respective estimated useful lives. Real estate assets were recorded at appraised values as of the acquisition date. The Company has estimated the remaining useful life of the home office building to be 25 years . Land is not depreciated. The Company depreciates its assets using the straight-line method over the estimated useful lives of the assets. The Company’s furniture is depreciated over a ten year useful life, office equipment and machines are depreciated over a five year useful life, and computers are depreciated over a three year useful life. Major repairs or improvements ar e capitalized and depreciated over the estimated useful lives of the assets. Other repairs are expensed as incurred. The cost and related accumulated depreciation of property and equipment sold or retired are removed from the accounts, and resulting gains or losses are included in income. Property and equipment consisted of the following: Successor Company As of December 31, 2017 2016 (Dollars In Thousands) Home office building $ 68,123 $ 67,279 Data processing equipment 24,102 21,749 Other, principally furniture and equipment 13,871 6,331 Total property and equipment subject to depreciation 106,096 95,359 Accumulated depreciation (21,305 ) (16,573 ) Land 24,920 24,920 Total property and equipment $ 109,711 $ 103,706 Separate Accounts The separate account assets represent funds for which the Company does not bear the investment risk. These assets are carried at fair value and are equal to the separate account liabilities, which represent the policyholder's equity in those assets. The investment income and investment gains and losses on the separate account assets accrue directly to the policyholder. These amounts are reported separately as assets and liabilities related to separate accounts in the accompanying consolidated financial statements. Amounts assessed against policy account balances for the costs of insurance, policy administration, and other services are included in premiums and policy fees in the accompanying consolidated statements of income. Stable Value Product Account Balances The Stable Value Products segment sells fixed and floating rate funding agreements directly to qualified institutional investors. The segment also issues funding agreements to the Federal Home Loan Bank ("FHLB"), and markets guaranteed investment contracts ("GICs") to 401(k) and other qualified retirement savings plans. GICs are contracts which specify a return on deposits for a specified period and often provide flexibility for withdrawals at book value in keeping with the benefits provided by the plan. The Company records its stable value contract liabilities in the consolidated balance sheets in “stable value product account balances” at the deposit amount plus accrued interest, adjusted for any unamortized premium or discount. Interest on the contracts is accrued based upon contract terms. Any premium or discount is amortized using the effective yield method. The segment’s products complement the Company’s overall asset/liability management in that the terms may be tailored to the needs of the Company as the seller of the contracts. Stable value product account balances include GICs and funding agreements the Company has issued. As of December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), the Company had $3,337.9 million and $1,872.5 million , respectively, of stable value product account balances marketed through structured programs. Most GICs and funding agreements the Company has written have maturities of one to twelve years . As of December 31, 2017 (Successor Company), future maturities of stable value products were as follows: Year of Maturity Amount (Dollars In Millions) 2018 $ 888.0 2019 - 2020 2,479.5 2021 - 2022 1,201.0 Thereafter 124.8 Derivative Financial Instruments The Company records its derivative financial instruments in the consolidated balance sheet in "other long-term investments" and "other liabilities" in accordance with GAAP, which requires that all derivative instruments be recognized in the balance sheet at fair value. The change in the fair value of derivative financial instruments is reported either in the statement of income or in the statement of other comprehensive income (loss), depending upon whether the derivative instrument qualified for and also has been properly identified as being part of a hedging relationship, and also on the type of hedging relationship that exists. For cash flow hedges, the effective portion of their gain or loss is reported as a component of other comprehensive income (loss) and reclassified into earnings in the period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. Effectiveness of the Company's hedge relationships is assessed on a quarterly basis. The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship in earnings. Changes in the fair value of derivatives that are recognized in current earnings are reported in "Realized investment gains (losses)—Derivative financial instruments". For additional information, see Note 7, Derivative Financial Instruments . Insurance Liabilities and Reserves Establishing an adequate liability for the Company's obligations to policyholders requires the use of certain assumptions. Estimating liabilities for future policy benefits on life and health insurance products requires the use of assumptions relative to future investment yields, mortality, morbidity, persistency, and other assumptions based on the Company's historical experience, modified as necessary to reflect anticipated trends and to include provisions for possible adverse deviation. Determining liabilities for the Company's property and casualty insurance products also requires the use of assumptions, including the projected levels of used vehicle prices, the frequency and severity of claims, and the effectiveness of internal processes designed to reduce the level of claims. The Company's results depend significantly upon the extent to which its actual claims experience is consistent with the assumptions the Company used in determining its reserves and pricing its products. The Company's reserve assumptions and estimates require significant judgment and, therefore, are inherently uncertain. The Company cannot determine with precision the ultimate amounts that it will pay for actual claims or the timing of those payments. Guaranteed Living Withdrawal Benefits The Company also establishes reserves for guaranteed living withdrawal benefits (“GLWB”) on its variable annuity (“VA”) products. The GLWB is valued in accordance with FASB guidance under the ASC Derivatives and Hedging Topic which utilizes the valuation technique prescribed by the ASC Fair Value Measurements and Disclosures Topic, which requires the embedded derivative to be recorded at fair value using current implied volatilities for the equity indices. The fair value of the GLWB is impacted by equity market conditions and can result in the GLWB embedded derivative being in an overall net asset or net liability position. In times of favorable equity market conditions the likelihood and severity of claims is reduced and expected fee income increases. Since claims are generally expected later than fees, these favorable equity market conditions can result in the present value of fees being greater than the present value of claims, which results in a net GLWB embedded derivative asset. In times of unfavorable equity market conditions the likelihood and severity of claims is increased and expected fee income decreases and can result in the present value of claims exceeding the present value of fees resulting in a net GLWB embedded derivative liability. The methods used to estimate the embedded derivatives employ assumptions about mortality, lapses, policyholder behavior, equity market returns, interest rates, and market volatility. The Company assumes age-based mortality from the Ruark 2015 ALB adjusted table for company experience. Differences between the actual experience and the assumptions used result in variances in profit and could result in losses. The Company reinsures certain risks associated with the GLWB to Shades Creek Captive Insurance (“Shades Creek”), a direct wholly owned insurance subsidiary of PLC. As of December 31, 2017 (Successor Company), the Company’s net GLWB liability held, including the impact of reinsurance, was $15.5 million . Goodwill The balance recognized as goodwill is not amortized, but is reviewed for impairment on an annual basis, or more frequently as events or circumstances may warrant, including those circumstances which would more likely than not reduce the fair value of the Company’s reporting units below its carrying amount. Accounting for goodwill requires an estimate of the future profitability of the associated lines of business within the Company's operating segments to assess the recoverability of the capitalized acquisition goodwill. The Company’s material goodwill balances are attributable to certain of its operating segments (which are each considered to be reporting units). The Company evaluates the carrying value of goodwill at the segment (or reporting unit) level at least annually and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Such circumstances could include, but are not limited to: 1) a significant adverse change in legal factors or in business climate, 2) unanticipated competition, or 3) an adverse action or assessment by a regulator. When evaluating whether goodwill is impaired, the Company first determines through qualitative analysis whether relevant events and circumstances indicate that it is more likely than not that segment goodwill balances are impaired as of the testing date. If the qualitative analysis does not indicate that an impairment of segment goodwill is more likely than not then no other specific quantitative impairment testing is required. If it is determined that it is more likely than not that impairment exists, the Company performs a quantitative assessment and compares its estimate of the fair value of the reporting unit to which the goodwill is assigned to the reporting unit’s carrying amount, including goodwill. The Company utilizes a fair value measurement (which includes a discounted cash flows analysis) to assess the carrying value of the reporting units in consideration of the recoverability of the goodwill balance assigned to each reporting unit as of the measurement date. The cash flows used to determine the fair value of the Company’s reporting units are dependent on a number of significant assumptions. The Company’s estimates, which consider a market participant view of fair value, are subject to change given the inherent uncertainty in predicting future results and cash flows, which are impacted by such things as policyholder behavior, competitor pricing, capital limitations, new product introductions, and specific industry and market conditions. Income Taxes The Company 's income tax returns, except for MONY which files separately, are included in PLC's consolidated U.S. income tax return. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the "Tax Reform Act"). Further information on the tax impacts of the Tax Reform Act is included in Note 19, Income Taxes . The Company uses the asset and liability method of accounting for income taxes. Generally, most items in pretax book income are also included in taxable income in the same year. However, some items are recognized for book purposes and for tax purposes in different years or are never recognized for either book or tax purposes. Those differences that will never be recognized for either book or tax purposes are permanent differences (e.g., the dividends-received deduction). As a result, the effective tax rate reflected in the financial statements may differ from the statutory rate reflected in the tax return. Those differences that are reported in different years for book and tax purposes are temporary and will reverse over time (e.g., the valuation of future policy benefits). These temporary differences are accounted for in the intervening periods as deferred tax assets and liabilities. Deferred tax assets generally represent revenue that is taxable before it is recognized in financial income and expenses that are deductible after they are recognized in financial income. Deferred tax liabilities generally represent revenues that are taxable after they are recognized in financial income or expenses or losses that are deductible before they are recognized in financial income. Components of accumulated other comprehensive income (loss) ("AOCI") are presented net of tax, and it is the Company's policy to use the aggregate portfolio approach to clear the disproportionate tax effects that remain in AOCI as a result of tax rate changes and certain other events. Under the aggregate portfolio approach, disproportionate tax effects are cleared only when the portfolio of investments that gave rise to the deferred tax item is sold or otherwise disposed of in its entirety. The application of GAAP requires the Company to evaluate the recoverability of the Company’s deferred tax assets and establish a valuation allowance, if necessary, to reduce the Company’s deferred tax assets to an amount that is more likely than not to be realized. Considerable judgment is required in determining whether a valuation allowance is necessary, and if so, the amount of such valuation allowance. In evaluating the need for a valuation allowance the Company may consider many factors, including: (1) the nature of the deferred tax assets and liabilities; (2) whether they are ordinary or capital; (3) in which tax jurisdictions they were generated and the timing of their reversal; (4) taxable income in prior carryback years as well as projected taxable earnings exclusive of reversing temporary differences and carryforwards; (5) the length of time that carryovers can be utilized in the various taxing jurisdictions; (6) any unique tax rules that would impact the utilization of the deferred tax assets; and (7) any tax planning strategies that the Company would employ to avoid a tax benefit from expiring unused. Although realization is not assured, management believes it is more likely than not that the deferred tax assets, net of valuation allowances, will be realized. GAAP prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that a company has taken or expects to take on tax returns. The application of this guidance is a two-step process, the first step being recognition. The Company determines whether it is more likely than not, based on the technical merits, that the tax position will be sustained upon examination. If a tax position does not meet the more likely than not recognition threshold, the benefit of that position is not recognized in the financial statements. The second step is measurement. The Company measures the tax position as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate resolution with a taxing authority that has full knowledge of all relevant information. This measurement considers the amounts and probabilities of the outcomes that could be realized upon ultimate settlement using the facts, circumstances, and information available at the reporting date. The Company’s liability for income taxes includes the liability for unrecognized tax benefits, interest and penalties which relate to tax years still subject to review by the Internal Revenue Service (“IRS”) or other taxing jurisdictions. Audit periods remain open for review until the statute of limitations expires. Generally, for tax years which produce net operating losses, capital losses or tax credit carryforwards, the statute of limitations does not close until the expiration of the statute of limitations for the tax year in which they are fully utilized. The completion of review or the expiration of the statute of limitations for a given audit period could result in an adjustment to the liability for income taxes. The Company classifies all interest and penalties related to tax uncertainties as income tax expense. See Note 19, Income Taxes, for additional information regarding income taxes. Variable Interest Entities The Company holds certain investments in entities in which its ownership interests could possibly be considered variable interests under Topic 810 of the FASB ASC (excluding debt and equity securities held as trading, available-for-sale, or held-to-maturity). The Company reviews the characteristics of each of these applicable entities and compares those characteristics to applicable criteria to determine whether the entity is a Variable Interest Entity ("VIE"). If the entity is determined to be a VIE, the Company then performs a detailed review to determine whether the interest would be considered a variable interest under the guidance. The Company then performs a qualitative review of all variable interests with the entity and determines whether the Company is the primary beneficiary. ASC 810 provides that an entity is the primary beneficiary of a VIE if the entity has 1) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance, and 2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.

SIGNIFICANT TRANSACTIONS	SIGNIFICANT TRANSACTIONS Reinsurance and Financing Transactions On January 15, 2016, PLC and the Company completed the transaction contemplated by the Master Agreement, dated September 30, 2015 (the “Master Agreement”), with Genworth Life and Annuity Insurance Company (“GLAIC”). Pursuant to the Master Agreement, effective January 1, 2016, the Company entered into a reinsurance agreement (the “Reinsurance Agreement”) under the terms of which the Company coinsures certain term life insurance business of GLAIC (the “GLAIC Block”). In connection with the reinsurance transaction, on January 15, 2016, Golden Gate Captive Insurance Company (“Golden Gate”), a wholly owned subsidiary of the Company, and Steel City, LLC (“Steel City”), a newly formed wholly owned subsidiary of PLC, entered into an 18 -year transaction to finance $2.188 billion of “XXX” reserves related to the acquired GLAIC Block and the other term life insurance business reinsured to Golden Gate by the Company and West Coast Life Insurance Company (“WCL”), a direct wholly owned subsidiary of the Company. Steel City issued notes with an aggregate initial principal amount of $2.188 billion to Golden Gate in exchange for a surplus note issued by Golden Gate with an initial principal amount of $2.188 billion . Through the structure, Hannover Life Reassurance Company of America (Bermuda) Ltd., The Canada Life Assurance Company (Barbados Branch) and Nomura Americas Re Ltd. (collectively, the “Risk-Takers”) provide credit enhancement to the Steel City notes for the 18 -year term in exchange for credit enhancement fees. The transaction is “non-recourse” to PLC, WCL and the Company, meaning that none of these companies are liable to reimburse the Risk-Takers for any credit enhancement payments required to be made. In connection with the transaction, PLC has entered into certain support agreements under which it guarantees or otherwise supports certain obligations of Golden Gate or Steel City, including a guarantee of the fees to the Risk-Takers. As a result of the financing transaction described above, the $800 million of Golden Gate Series A Surplus Notes held by PLC were contributed to the Company and then subsequently contributed to Golden Gate, which resulted in the extinguishment of these notes. Also on January 15, 2016, Golden Gate paid an extraordinary dividend of $300 million to the Company as approved by the Vermont Department of Financial Regulation. The transactions described above resulted in an increase to total assets and total liabilities of approximately $2.8 billion . Of the approximate $2.8 billion increase in total assets, $0.6 billion was the result of the reinsurance transaction with GLAIC which included a $280 million increase in VOBA. The remaining $2.2 billion increase to total assets and liabilities is associated with the financing transaction between Golden Gate and Steel City. The Company considered whether the Reinsurance Agreement constituted the purchase of a business for accounting and reporting purposes pursuant to ASC 805, Business Combinations. While the transaction included a continuation of the certain revenue-producing activities associated with the reinsured policies, it did not result in the acquisition of a market distribution system, sales force or production techniques. Based on Management’s decision not to pursue distribution opportunities or future sales related to the reinsured policies, the Company accounted for the transaction as a reinsurance agreement under ASC 944, Insurance Contracts and asset acquisition under ASC 805. Accordingly, the Company recorded the assets and liabilities acquired under the reinsurance agreement at fair value and recognized an intangible asset, VOBA, equal to the excess of the fair value of assets acquired over liabilities assumed, measured in accordance with the Company's accounting policies for insurance and reinsurance contracts that it issues or holds pursuant to ASC 944. USWC Holding Company Acquisition On December 1, 2016, the Company completed the acquisition of the Pompano Beach, Florida-based USWC Holding Company (“US Warranty”) pursuant to a Stock Purchase Agreement. US Warranty's primary operating subsidiary is United States Warranty Corp., which currently markets vehicle service contracts, GAP coverage, and a suite of ancillary automotive maintenance and protection products nationwide. This acquisition has provided the Company's Asset Protection segment and USWC with expanded market reach, enhanced product and operational capabilities, and higher collective growth potential. The transaction was accounted for under the acquisition method of accounting under ASC Topic 805. In accordance with ASC Topic 805-20-30, all identifiable assets acquired and liabilities assumed were measured at fair value as of the acquisition date. On the acquisition date, goodwill of $61.0 million represented the cost in excess of the fair value of net assets acquired (including identifiable intangibles), and reflected the US Warranty's assembled workforce, future growth potential and other sources of value not associated with identifiable assets. The Company acquired 100% of voting equity interests. The aggregate purchase price for US Warranty was $136.1 million . The amount recorded as the value of business acquired at December 1, 2016, represents the actuarially estimated present value of after-tax future cash flows, adjusted for statutory reserve differences and cost of capital, from the policies acquired through the US Warranty acquisition. This amount will be amortized in proportion with the gross premiums or estimated net profits of the acquired insurance contracts. The following table summarizes the fair values of the net assets acquired as of the acquisition date: Fair Value As of December 1, 2016 (Dollars in Thousands) Assets Fixed maturities $ 10,592 Other long-term investments 2,340 Cash 122,167 Accrued investment income 52 Accounts and premiums receivables 18,536 Reinsurance receivable 9,397 Value of businesses acquired 5,079 Goodwill 61,027 Other intangibles 70,400 Property and equipment 390 Accrued income taxes 4,161 Other assets 40 Total assets 304,181 Liabilities Unearned premiums $ 82,757 Other policyholders' funds 21,483 Other liabilities 24,951 Deferred income taxes 38,929 Total liabilities 168,120 Net assets acquired $ 136,061 Intangible assets recognized by the Company included the following (excluding goodwill): Estimated Fair Value on Estimated Acquisition Date Useful Life (Dollars In Thousands) (In Years) Distribution relationships $ 65,000 13-21 Trade names 1,400 5-6 Technology 4,000 8-11 Total intangible assets $ 70,400 Identified intangible assets were valued using the excess earnings method, relief from royalty method or cost approach, as appropriate. Amortizable intangible assets will be amortized straight line over their assigned useful lives. The following is a schedule of future estimated aggregate amortization expense: Year Amount (Dollars In Thousands) 2017 $ 4,843 2018 4,843 2019 4,843 2020 4,843 2021 4,843 The following (unaudited) pro forma condensed consolidated results of operations assumes that the acquisition of US Warranty was completed as of January 1, 2015: Successor Company For The Year Ended December 31, 2016 February 1, 2015 to December 31, 2015 (Dollars In Thousands) Revenue (1) $ 4,342,054 $ 3,530,073 Net income (2) 352,856 179,877 (1) Includes $4.7 million of revenue recognized in the Company's net income for year ended December 31, 2016 (Successor Company). (2) Includes $0.2 million of net income recognized in the Company's net income for the year ended December 31, 2016 (Successor Company). The pro forma information above is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisition been consummated as of that time, not is it intended to be a projection of future results. REINSURANCE The Company reinsures certain of its risks with (cedes), and assumes risks from, other insurers under yearly renewable term, coinsurance, and modified coinsurance agreements. Under yearly renewable term agreements, the Company reinsures only the mortality risk, while under coinsurance the Company reinsures a proportionate share of all risks arising under the reinsured policy. Under coinsurance, the reinsurer receives a proportionate share of the premiums less commissions and is liable for a corresponding share of all benefit payments. Modified coinsurance is accounted for in a manner similar to coinsurance except that the liability for future policy benefits is held by the ceding company, and settlements are made on a net basis between the companies. 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 us under the terms of the reinsurance agreements. The Company monitors the concentration of credit risk the Company has with any reinsurer, as well as the financial condition of its reinsurers. As of December 31, 2017 (Successor Company), the Company had reinsured approximately 38% of the face value of its life insurance in-force. The Company has reinsured approximately 16% of the face value of its life insurance in-force with the following three reinsurers: • Security Life of Denver Insurance Co. (currently administered by Hannover Re) • Swiss Re Life & Health America Inc. • The Lincoln National Life Insurance Co. (currently administered by Swiss Re Life & Health America Inc.) The Company has not experienced any credit losses for the years ended December 31, 2017 (Successor Company), December 31, 2016 (Successor Company), or December 31, 2015 (Successor Company) related to these reinsurers. The Company has set limits on the amount of insurance retained on the life of any one person. The amount of insurance retained by the Company on any one life on traditional life insurance was $500,000 in years prior to mid-2005. In 2005, this retention amount was increased to $1,000,000 for certain policies, and during 2008, it was increased to $2,000,000 for certain policies. During 2016, the retention amount was increased to $5,000,000 . Reinsurance premiums, commissions, expense reimbursements, benefits, and reserves related to reinsured long-duration contracts are accounted for over the life of the underlying reinsured contracts using assumptions consistent with those used to account for the underlying contracts. The cost of reinsurance related to short-duration contracts is accounted for over the reinsurance contract period. Amounts recoverable from reinsurers, for both short- and long-duration reinsurance arrangements, are estimated in a manner consistent with the claim liabilities and policy benefits associated with reinsured policies. The following table presents the net life insurance in-force: Successor Company As of December 31, 2017 2016 (Dollars In Millions) Direct life insurance in-force $ 751,512 $ 739,249 Amounts assumed from other companies 110,205 116,265 Amounts ceded to other companies (328,377 ) (348,995 ) Net life insurance in-force $ 533,340 $ 506,519 Percentage of amount assumed to net 21 % 23 % The following table reflects the effect of reinsurance on life, accident/health, and property and liability insurance premiums written and earned: Gross Amount Ceded to Other Companies Assumed from Other Companies Net Amount (Dollars In Thousands) Successor Company For The Year Ended December 31, 2017 Premiums and policy fees: -1 Life insurance $ 2,655,846 $ (1,230,258 ) $ 435,113 $ 1,860,701 (1) Accident/health insurance 51,991 (33,052 ) 14,946 33,885 Property and liability insurance 288,809 (103,786 ) 9,657 194,680 Total $ 2,996,646 $ (1,367,096 ) $ 459,716 $ 2,089,266 For The Year Ended December 31, 2016 Premiums and policy fees: Life insurance $ 2,610,682 $ (1,207,159 ) $ 454,999 $ 1,858,522 (1) Accident/health insurance 58,076 (36,935 ) 17,439 38,580 Property and liability insurance 242,517 (86,629 ) 5,706 161,594 Total $ 2,911,275 $ (1,330,723 ) $ 478,144 $ 2,058,696 February 1, 2015 to December 31, 2015 Premiums and policy fees: Life insurance $ 2,360,643 $ (1,058,706 ) $ 308,280 $ 1,610,217 (1) Accident/health insurance 70,243 (36,871 ) 18,252 51,624 Property and liability insurance 228,500 (79,294 ) 6,904 156,110 Total $ 2,659,386 $ (1,174,871 ) $ 333,436 $ 1,817,951 Gross Amount Ceded to Other Companies Assumed from Other Companies Net Amount (Dollars In Thousands) Predecessor Company January 1, 2015 to January 31, 2015 Premiums and policy fees: Life insurance $ 204,185 $ (80,657 ) $ 28,601 $ 152,129 (1) Accident/health insurance 6,846 (4,621 ) 1,809 4,034 Property and liability insurance 18,475 (6,354 ) 666 12,787 Total $ 229,506 $ (91,632 ) $ 31,076 $ 168,950 (1) Includes annuity policy fees of $173.5 million , $80.1 million , $77.2 million , and $7.7 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), the periods of February 1, 2015 to December 31, 2015 (Successor Company) and January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. As of December 31, 2017 and 2016 (Successor Company), policy and claim reserves relating to insurance ceded of $4.8 billion and $5.1 billion , respectively, are included in reinsurance receivables. Should any of the reinsurers be unable to meet its obligation at the time of the claim, the Company would be obligated to pay such claims. As of December 31, 2017 and 2016 (Successor Company), the Company had paid $96.6 million and $87.9 million , respectively, of ceded benefits which are recoverable from reinsurers. In addition, as of December 31, 2017 and 2016 (Successor Company), the Company had receivables of $65.1 million and $64.5 million , respectively, related to insurance assumed. The Company’s third party reinsurance receivables amounted to $4.8 billion and $5.1 billion as of December 31, 2017 and 2016 (Successor Company), respectively. These amounts include ceded reserve balances and ceded benefit payments. The ceded benefit payments are recoverable from reinsurers.

In general, the reinsurers' ability to terminate coverage for existing cessions is limited to such circumstances as material breach of contract or non-payment of premiums by the ceding company. The reinsurance contracts generally contain provisions intended to provide the ceding company with the ability to cede future business on a basis consistent with historical terms. However, either party may terminate any of the contracts with respect to future business upon appropriate notice to the other party. Generally, the reinsurance contracts do not limit the overall amount of the loss that can be incurred by the reinsurer. The amount of liabilities ceded under contracts that provide for the payment of experience refunds is immaterial.

MONY CLOSED BLOCK OF BUSINESS

MONY CLOSED BLOCK OF BUSINESS	12 Months Ended

Closed Block Disclosure [Abstract]
MONY CLOSED BLOCK OF BUSINESS	MONY CLOSED BLOCK OF BUSINESS In 1998, MONY Life Insurance Company (“MONY”) converted from a mutual insurance company to a stock corporation (“demutualization”). In connection with its demutualization, an accounting mechanism known as a closed block (the “Closed Block”) was established for certain individuals’ participating policies in force as of the date of demutualization. Assets, liabilities, and earnings of the Closed Block are specifically identified to support its participating policyholders. The Company acquired the Closed Block in conjunction with the acquisition of MONY in 2013. Assets allocated to the Closed Block inure solely to the benefit of each Closed Block’s policyholders and will not revert to the benefit of MONY or the Company. No reallocation, transfer, borrowing or lending of assets can be made between the Closed Block and other portions of MONY’s general account, any of MONY’s separate accounts or any affiliate of MONY without the approval of the Superintendent of The New York State Department of Financial Services (the “Superintendent”). Closed Block assets and liabilities are carried on the same basis as similar assets and liabilities held in the general account. The excess of Closed Block liabilities over Closed Block assets (adjusted to exclude the impact of related amounts in AOCI) at the acquisition date of October 1, 2013, represented the estimated maximum future post-tax earnings from the Closed Block that would be recognized in income from continuing operations over the period the policies and contracts in the Closed Block remain in force. In connection with the acquisition of MONY, the Company developed an actuarial calculation of the expected timing of MONY’s Closed Block’s earnings as of October 1, 2013. Pursuant to the acquisition of the Company by Dai-ichi Life, this actuarial calculation of the expected timing of MONY’s Closed Block earnings was recalculated and reset as of February 1, 2015, along with the establishment of a policyholder dividend obligation as of such date. If the actual cumulative earnings from the Closed Block are greater than the expected cumulative earnings, only the expected earnings will be recognized in the Company's net income. Actual cumulative earnings in excess of expected cumulative earnings at any point in time are recorded as a policyholder dividend obligation because they will ultimately be paid to Closed Block policyholders as an additional policyholder dividend, unless offset by future performance that is less favorable than originally expected. If a policyholder dividend obligation has been previously established and the actual Closed Block earnings in a subsequent period are less than the expected earnings for that period, the policyholder dividend obligation would be reduced (but not below zero). If, over the period the policies and contracts in the Closed Block remain in force, the actual cumulative earnings of the Closed Block are less than the expected cumulative earnings, only actual earnings would be recognized in income from continuing operations. If the Closed Block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from assets outside the Closed Block. Many expenses related to Closed Block operations, including amortization of VOBA, are charged to operations outside of the Closed Block; accordingly, net revenues of the Closed Block do not represent the actual profitability of the Closed Block operations. Operating costs and expenses outside of the Closed Block are, therefore, disproportionate to the business outside of the Closed Block. Summarized financial information for the Closed Block as of December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company) and is as follows: Successor Company As of December 31, 2017 2016 (Dollars In Thousands) Closed block liabilities Future policy benefits, policyholders' account balances and other policyholder liabilities $ 5,791,867 $ 5,896,355 Policyholder dividend obligation 160,712 31,932 Other liabilities 30,764 40,007 Total closed block liabilities 5,983,343 5,968,294 Closed block assets Fixed maturities, available-for-sale, at fair value 4,669,856 4,440,105 Mortgage loans on real estate 108,934 201,088 Policy loans 700,769 712,959 Cash and other invested assets 31,182 108,270 Other assets 122,637 135,794 Total closed block assets 5,633,378 5,598,216 Excess of reported closed block liabilities over closed block assets 349,965 370,078 Portion of above representing accumulated other comprehensive income: Net unrealized investments gains (losses) net of policyholder dividend obligation: $(13,429) and $(197,450); and net of income tax: $2,820 and $69,107 — — Future earnings to be recognized from closed block assets and closed block liabilities $ 349,965 $ 370,078 Reconciliation of the policyholder dividend obligation is as follows: Successor Company For The Year Ended For The Year Ended (Dollars In Thousands) Policyholder dividend obligation, beginning balance $ 31,932 $ — Applicable to net revenue (losses) (55,241 ) (46,557 ) Change in net unrealized investment gains (losses) allocated to policyholder dividend obligation 184,021 78,489 Policyholder dividend obligation, ending balance $ 160,712 $ 31,932 Closed Block revenues and expenses were as follows: Successor Company Predecessor Company For The Year Ended For The Year Ended February 1, 2015 to December 31, 2015 January 1, 2015 to January 31, 2015 (Dollars In Thousands) (Dollars In Thousands) Revenues Premiums and other income $ 180,097 $ 189,700 $ 185,562 $ 15,065 Net investment income 203,964 211,175 193,203 19,107 Net investment gains 910 1,524 3,333 568 Total revenues 384,971 402,399 382,098 34,740 Benefits and other deductions Benefits and settlement expenses 335,200 353,488 336,629 31,152 Other operating expenses 1,940 2,804 1,001 — Total benefits and other deductions 337,140 356,292 337,630 31,152 Net revenues before income taxes 47,831 46,107 44,468 3,588 Income tax expense 27,718 16,137 14,920 1,256 Net revenues $ 20,113 $ 29,970 $ 29,548 $ 2,332

Factors such as the credit enhancement within the deal structure, the average life of the securities, and the performance of the underlying collateral support the recoverability of these investments. The other asset-backed securities have a gross unrealized loss greater than twelve months of $5.4 million as of December 31, 2017 (Successor Company). This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the Federal Family Education Loan Program ("FFELP"). At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary. The U.S. government-related securities and the other government-related securities had gross unrealized losses greater than twelve months of $31.5 million and $4.8 million as of December 31, 2017 (Successor Company), respectively. These declines were related to changes in interest rates. The states, municipalities, and political subdivisions categories had gross unrealized losses greater than twelve months of $43.9 million as of December 31, 2017 (Successor Company). These declines were related to changes in interest rates. The corporate securities category has gross unrealized losses greater than twelve months of $471.8 million as of December 31, 2017 (Successor Company). The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information. As of December 31, 2017 (Successor Company), the Company had a total of 1,844 positions that were in an unrealized loss position, but the Company does not consider these unrealized loss positions to be other-than-temporary. This is based on the aggregate factors discussed previously and because the Company has the ability and intent to hold these investments until the fair values recover, and the Company does not intend to sell or expect to be required to sell the securities before recovering the Company’s amortized cost of the securities. The following table includes the gross unrealized losses and fair value of the Company’s investments that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of December 31, 2016 (Successor Company): Less Than 12 Months 12 Months or More Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss (Dollars In Thousands) Residential mortgage-backed securities $ 1,051,694 $ (21,178 ) $ 170,826 $ (4,117 ) $ 1,222,520 $ (25,295 ) Commercial mortgage-backed securities 1,426,252 (36,589 ) 100,475 (4,013 ) 1,526,727 (40,602 ) Other asset-backed securities 323,706 (9,291 ) 176,792 (11,407 ) 500,498 (20,698 ) U.S. government-related securities 1,237,942 (40,454 ) 3 (1 ) 1,237,945 (40,455 ) Other government-related securities 98,412 (2,907 ) 79,393 (11,890 ) 177,805 (14,797 ) States, municipalities, and political subdivisions 1,062,368 (63,809 ) 548,254 (41,749 ) 1,610,622 (105,558 ) Corporate securities 12,490,517 (467,463 ) 9,791,313 (1,114,635 ) 22,281,830 (1,582,098 ) Redeemable preferred stock 66,781 (6,642 ) 19,062 (1,877 ) 85,843 (8,519 ) Equities 411,845 (15,273 ) 69,497 (6,412 ) 481,342 (21,685 ) $ 18,169,517 $ (663,606 ) $ 10,955,615 $ (1,196,101 ) $ 29,125,132 $ (1,859,707 ) RMBS and CMBS had gross unrealized losses greater than twelve months of $4.1 million and $4.0 million , respectively, as of December 31, 2016 (Successor Company).

This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the Federal Family Education Loan Program ("FFELP"). At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary. The other government-related securities had gross unrealized losses greater than twelve months of $11.9 million as of December 31, 2016 (Successor Company). These declines were related to changes in interest rates. The states, municipalities, and political subdivisions categories had gross unrealized losses greater than twelve months of $41.7 million as of December 31, 2016 (Successor Company). These declines were related to changes in interest rates. The corporate securities category has gross unrealized losses greater than twelve months of $1.1 billion as of December 31, 2016 (Successor Company). The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information. As of December 31, 2017 (Successor Company), the Company had securities in its available-for-sale portfolio which were rated below investment grade with a fair value of $1.9 billion and had an amortized cost of $1.9 billion . In addition, included in the Company’s trading portfolio, the Company held $228.9 million of securities which were rated below investment grade. Approximately $310.7 million of the below investment grade securities held by the Company were not publicly traded. The change in unrealized gains (losses), net of income tax, on fixed maturity and equity securities, classified as available-for-sale is summarized as follows: Successor Company Predecessor Company For The Year Ended December 31, 2017 For The Year Ended December 31, 2016 February 1, 2015 January 1, 2015 (Dollars In Thousands) (Dollars In Thousands) Fixed maturities $ 1,083,865 $ 802,248 $ (1,873,795 ) 669,160 Equity securities 17,863 (13,463 ) 4,406 12,172 The amortized cost and fair value of the Company’s investments classified as held-to-maturity as of December 31, 2017 and 2016 (Successor Company), are as follows: Successor Company Amortized Gross Unrecognized Holding Gains Gross Unrecognized Holding Losses Fair Value Total OTTI Recognized in OCI As of December 31, 2017 (Dollars In Thousands) Fixed maturities: Securities issued by affiliates: Red Mountain LLC $ 704,904 $ — $ (19,163 ) $ 685,741 $ — Steel City LLC 2,014,000 76,586 — 2,090,586 — $ 2,718,904 $ 76,586 $ (19,163 ) $ 2,776,327 $ — Successor Company Amortized Gross Gross Fair Value Total OTTI Recognized in OCI As of December 31, 2016 (Dollars In Thousands) Fixed maturities: Securities issued by affiliates: Red Mountain LLC $ 654,177 $ — $ (67,222 ) $ 586,955 $ — Steel City LLC 2,116,000 30,385 — 2,146,385 — $ 2,770,177 $ 30,385 $ (67,222 ) $ 2,733,340 $ — During the year ended December 31, 2017 (Successor Company), the year ended December 31, 2016 (Successor Company), the period of February 1, 2015 to December 31, 2015 (Successor Company), and the period of January 1, 2015 to January 31, 2015 (Predecessor Company), the Company did no t record any other-than-temporary impairments on held-to-maturity securities. The Company’s held-to-maturity securities had $76.6 million of gross unrecognized holding gains and $19.2 million of gross unrecognized holding losses by maturity as of December 31, 2017 (Successor Company). The Company does not consider these unrecognized holding losses to be other-than-temporary based on certain positive factors associated with the securities which include credit ratings of the guarantor, financial health of the issuer and guarantor, continued access of the issuer to capital markets and other pertinent information. These held-to-maturity securities are issued by affiliates of the Company which are considered VIE's. The Company is not the primary beneficiary of these entities and thus the securities are not eliminated in consolidation. These securities are collateralized by non-recourse funding obligations issued by captive insurance companies that are affiliates of the Company. The Company’s held-to-maturity securities had $30.4 million of gross unrecognized holding gains and $67.2 million of gross unrecognized holding losses by maturity as of December 31, 2016 (Successor Company). The Company does not consider these unrecognized holding losses to be other-than-temporary based on certain positive factors associated with the securities which include credit ratings of the guarantor, financial health of the issuer and guarantor, continued access of the issuer to capital markets and other pertinent information. The Company held $17.5 million of non-income producing securities for the year ended December 31, 2017 (Successor Company). Included in the Company’s invested assets are $1.6 billion of policy loans as of December 31, 2017 (Successor Company). The interest rates on standard policy loans range from 3.0% to 8.0% . The collateral loans on life insurance policies have an interest rate of 13.64% . Variable Interest Entities The Company holds certain investments in entities in which its ownership interests could possibly be considered variable interests under Topic 810 of the FASB ASC (excluding debt and equity securities held as trading, available for sale, or held to maturity). The Company reviews the characteristics of each of these applicable entities and compares those characteristics to applicable criteria to determine whether the entity is a Variable Interest Entity ("VIE"). If the entity is determined to be a VIE, the Company then performs a detailed review to determine whether the interest would be considered a variable interest under the guidance. The Company then performs a qualitative review of all variable interests with the entity and determines whether the Company is the primary beneficiary. ASC 810 provides that an entity is the primary beneficiary of a VIE if the entity has 1) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance, and 2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Based on this analysis, the Company had an interest in one wholly owned subsidiary, Red Mountain, LLC (“Red Mountain”), that was determined to be a VIE as of December 31, 2017 and 2016 (Successor Company). The activity most significant to Red Mountain is the issuance of a note in connection with a financing transaction involving Golden Gate V Vermont Captive Insurance Company ("Golden Gate V") and the Company in which Golden Gate V issued non-recourse funding obligations to Red Mountain and Red Mountain issued the note to Golden Gate V. Credit enhancement on the Red Mountain Note is provided by an unrelated third party. For details of this transaction, see Note 14, Debt and Other Obligations . The Company has the power, via its 100% ownership through an affiliate, to direct the activities of the VIE, but does not have the obligation to absorb losses related to the primary risks or sources of variability to the VIE. The variability of loss would be borne primarily by the third party in its function as provider of credit enhancement on the Red Mountain Note. Accordingly, it was determined that the Company is not the primary beneficiary of the VIE. The Company's risk of loss related to the VIE is limited to its investment of $10,000 . Additionally, PLC, the holding company, has guaranteed Red Mountain's payment obligation for the credit enhancement fee to the unrelated third party provider. As of December 31, 2017 (Successor Company), no payments have been made or required related to this guarantee. Steel City, a newly formed wholly owned subsidiary of the Company, entered into a financing agreement on January 15, 2016 involving Golden Gate Captive Insurance Company, in which Golden Gate issued non-recourse funding obligations to Steel City and Steel City issued three notes (the “Steel City Notes”) to Golden Gate. Credit enhancement on the Steel City Notes is provided by unrelated third parties. For details of the financing transaction, see Note 14, Debt and Other Obligations . The activity most significant to Steel City is the issuance of the Steel City Notes. The Company had the power, via its 100% ownership, to direct the activities of the VIE, but did not have the obligation to absorb losses related to the primary risks or sources of variability to the VIE. The variability of loss would be borne primarily by the third parties in their function as providers of credit enhancement on the Steel City Notes. Accordingly, it was determined that the Company is not the primary beneficiary of the VIE. The Company’s risk of loss related to the VIE is limited to its investment of $10,000 . Additionally, the Company has guaranteed Steel City’s payment obligation for the credit enhancement fee to the unrelated third party providers. As of December 31, 2017 (Successor Company), no payments have been made or required related to this guarantee.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS The Company determined the fair value of its financial instruments based on the fair value hierarchy established in FASB guidance referenced in the Fair Value Measurements and Disclosures Topic which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company has adopted the provisions from the FASB guidance that is referenced in the Fair Value Measurements and Disclosures Topic for non-financial assets and liabilities (such as property and equipment, goodwill, and other intangible assets) that are required to be measured at fair value on a periodic basis. The effect on the Company's periodic fair value measurements for non-financial assets and liabilities was not material. The Company has categorized its financial instruments, based on the priority of the inputs to the valuation technique, into a three level hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the consolidated balance sheets are categorized as follows: • Level 1: Unadjusted quoted prices for identical assets or liabilities in an active market. • Level 2: Quoted prices in markets that are not active or significant inputs that are observable either directly or indirectly. Level 2 inputs include the following: a) Quoted prices for similar assets or liabilities in active markets b) Quoted prices for identical or similar assets or liabilities in non-active markets c) Inputs other than quoted market prices that are observable d) Inputs that are derived principally from or corroborated by observable market data through correlation or other means. • Level 3: Prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. They reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. The following table presents the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 (Successor Company): Level 1 Level 2 Level 3 Total (Dollars In Thousands) Assets: Fixed maturity securities - available-for-sale Residential mortgage-backed securities $ — $ 2,318,493 $ — $ 2,318,493 Commercial mortgage-backed securities — 1,860,488 — 1,860,488 Other asset-backed securities — 745,184 504,365 1,249,549 U.S. government-related securities 958,775 264,477 — 1,223,252 State, municipalities, and political subdivisions — 1,741,645 — 1,741,645 Other government-related securities 285,233 — 285,233 Corporate securities — 28,910,645 626,901 29,537,546 Redeemable preferred stock 72,471 18,620 — 91,091 Total fixed maturity securities - available-for-sale 1,031,246 36,144,785 1,131,266 38,307,297 Fixed maturity securities - trading Residential mortgage-backed securities — 259,694 — 259,694 Commercial mortgage-backed securities — 146,804 — 146,804 Other asset-backed securities — 102,875 35,222 138,097 U.S. government-related securities 21,183 6,051 — 27,234 State, municipalities, and political subdivisions — 326,925 — 326,925 Other government-related securities — 63,925 — 63,925 Corporate securities — 1,692,741 5,442 1,698,183 Redeemable preferred stock 3,327 — — 3,327 Total fixed maturity securities - trading 24,510 2,599,015 40,664 2,664,189 Total fixed maturity securities 1,055,756 38,743,800 1,171,930 40,971,486 Equity securities 649,981 — 65,517 715,498 Other long-term investments (1) 51,102 417,969 160,466 629,537 Short-term investments 394,394 132,750 — 527,144 Total investments 2,151,233 39,294,519 1,397,913 42,843,665 Cash 178,855 — — 178,855 Assets related to separate accounts Variable annuity 13,956,071 — — 13,956,071 Variable universal life 1,035,202 — — 1,035,202 Total assets measured at fair value on a recurring basis $ 17,321,361 $ 39,294,519 $ 1,397,913 $ 58,013,793 Liabilities: Annuity account balances (2) $ — $ — $ 83,472 $ 83,472 Other liabilities (1) 5,755 302,656 597,562 905,973 Total liabilities measured at fair value on a recurring basis $ 5,755 $ 302,656 $ 681,034 $ 989,445 (1) Includes certain freestanding and embedded derivatives.

(2) Represents liabilities related to fixed indexed annuities. Determination of Fair Values The valuation methodologies used to determine the fair values of assets and liabilities reflect market participant assumptions and are based on the application of the fair value hierarchy that prioritizes observable market inputs over unobservable inputs. The Company determines the fair values of certain financial assets and financial liabilities based on quoted market prices, where available. The Company also determines certain fair values based on future cash flows discounted at the appropriate current market rate. Fair values reflect adjustments for counterparty credit quality, the Company’s credit standing, liquidity, and where appropriate, risk margins on unobservable parameters. The following is a discussion of the methodologies used to determine fair values for the financial instruments as listed in the above table. The fair value of fixed maturity, short-term, and equity securities is determined by management after considering one of three primary sources of information: third party pricing services, non-binding independent broker quotations, or pricing matrices. Security pricing is applied using a ‘‘waterfall’’ approach whereby publicly available prices are first sought from third party pricing services, the remaining unpriced securities are submitted to independent brokers for non-binding prices, or lastly, securities are priced using a pricing matrix. Typical inputs used by these three pricing methods include, but are not limited to: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. Third party pricing services price approximately 92.7% of the Company’s available-for-sale and trading fixed maturity securities. Based on the typical trading volumes and the lack of quoted market prices for available-for-sale and trading fixed maturities, third party pricing services derive the majority of security prices from observable market inputs such as recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information outlined above. If there are no recent reported trades, the third party pricing services and brokers may use matrix or model processes to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Certain securities are priced via independent non-binding broker quotations, which are considered to have no significant unobservable inputs. When using non-binding independent broker quotations, the Company obtains one quote per security, typically from the broker from which we purchased the security. A pricing matrix is used to price securities for which the Company is unable to obtain or effectively rely on either a price from a third party pricing service or an independent broker quotation. The pricing matrix used by the Company begins with current spread levels to determine the market price for the security. The credit spreads, assigned by brokers, incorporate the issuer’s credit rating, liquidity discounts, weighted- average of contracted cash flows, risk premium, if warranted, due to the issuer’s industry, and the security’s time to maturity. The Company uses credit ratings provided by nationally recognized rating agencies. For securities that are priced via non-binding independent broker quotations, the Company assesses whether prices received from independent brokers represent a reasonable estimate of fair value through an analysis using internal and external cash flow models developed based on spreads and, when available, market indices. The Company uses a market-based cash flow analysis to validate the reasonableness of prices received from independent brokers. These analytics, which are updated daily, incorporate various metrics (yield curves, credit spreads, prepayment rates, etc.) to determine the valuation of such holdings. As a result of this analysis, if the Company determines there is a more appropriate fair value based upon the analytics, the price received from the independent broker is adjusted accordingly. The Company did not adjust any quotes or prices received from brokers during the year ended December 31, 2017 (Successor Company). The Company has analyzed the third party pricing services’ valuation methodologies and related inputs and has also evaluated the various types of securities in its investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs that is in accordance with the Fair Value Measurements and Disclosures Topic of the ASC. Based on this evaluation and investment class analysis, each price was classified into Level 1, 2, or 3. Most prices provided by third party pricing services are classified into Level 2 because the significant inputs used in pricing the securities are market observable and the observable inputs are corroborated by the Company. Since the matrix pricing of certain debt securities includes significant non-observable inputs, they are classified as Level 3. Asset-Backed Securities This category mainly consists of residential mortgage-backed securities, commercial mortgage-backed securities, and other asset-backed securities (collectively referred to as asset-backed securities or “ABS”). As of December 31, 2017 (Successor Company), the Company held $5.4 billion of ABS classified as Level 2. These securities are priced from information provided by a third party pricing service and independent broker quotes. The third party pricing services and brokers mainly value securities using both a market and income approach to valuation. As part of this valuation process they consider the following characteristics of the item being measured to be relevant inputs: 1) weighted-average coupon rate, 2) weighted-average years to maturity, 3) types of underlying assets, 4) weighted-average coupon rate of the underlying assets, 5) weighted-average years to maturity of the underlying assets, 6) seniority level of the tranches owned, and 7) credit ratings of the securities. After reviewing these characteristics of the ABS, the third party pricing service and brokers use certain inputs to determine the value of the security. For ABS classified as Level 2, the valuation would consist of predominantly market observable inputs such as, but not limited to: 1) monthly principal and interest payments on the underlying assets, 2) average life of the security, 3) prepayment speeds, 4) credit spreads, 5) treasury and swap yield curves, and 6) discount margin. The Company reviews the methodologies and valuation techniques (including the ability to observe inputs) in assessing the information received from external pricing services and in consideration of the fair value presentation. As of December 31, 2017 (Successor Company), the Company held $539.6 million of Level 3 ABS, which included $504.4 million of other asset-backed securities classified as available-for-sale and $35.2 million of other asset-backed securities classified as trading. These securities within the available-for-sale portfolio are predominantly ARS whose underlying collateral is at least 97% guaranteed by the FFELP. As a result of the ARS market collapse during 2008, the Company prices its ARS using an income approach valuation model. As part of the valuation process the Company reviews the following characteristics of the ARS in determining the relevant inputs: 1) weighted-average coupon rate, 2) weighted-average years to maturity, 3) types of underlying assets, 4) weighted-average coupon rate of the underlying assets, 5) weighted-average years to maturity of the underlying assets, 6) seniority level of the tranches owned, 7) credit ratings of the securities, 8) liquidity premium, and 9) paydown rate. In periods where market activity increases and there are transactions at a price that is not the result of a distressed or forced sale we consider those prices as part of our valuation. If the market activity during a period is solely the result of the issuer redeeming positions we consider those transactions in our valuation, but still consider them to be level three measurements due to the nature of the transaction. Corporate Securities, U.S. Government-Related Securities, States, Municipals, and Political Subdivisions, and Other Government Related Securities As of December 31, 2017 (Successor Company), the Company classified approximately $33.3 billion of corporate securities, U.S. government-related securities, states, municipals, and political subdivisions, and other government-related securities as Level 2. The fair value of the Level 2 securities is predominantly priced by broker quotes and a third party pricing service. The Company has reviewed the valuation techniques of the brokers and third party pricing service and has determined that such techniques used Level 2 market observable inputs. The following characteristics of the securities are considered to be the primary relevant inputs to the valuation: 1) weighted- average coupon rate, 2) weighted-average years to maturity, 3) seniority, and 4) credit ratings. The Company reviews the methodologies and valuation techniques (including the ability to observe inputs) in assessing the information received from external pricing services and in consideration of the fair value presentation. The brokers and third party pricing service utilize valuation models that consist of a hybrid income and market approach to valuation. The pricing models utilize the following inputs: 1) principal and interest payments, 2) treasury yield curve, 3) credit spreads from new issue and secondary trading markets, 4) dealer quotes with adjustments for issues with early redemption features, 5) liquidity premiums present on private placements, and 6) discount margins from dealers in the new issue market. As of December 31, 2017 (Successor Company), the Company classified approximately $632.3 million of securities as Level 3 valuations. Level 3 securities primarily represent investments in illiquid bonds for which no price is readily available. To determine a price, the Company uses a discounted cash flow model with both observable and unobservable inputs. These inputs are entered into an industry standard pricing model to determine the final price of the security. These inputs include: 1) principal and interest payments, 2) coupon rate, 3) sector and issuer level spread over treasury, 4) underlying collateral, 5) credit ratings, 6) maturity, 7) embedded options, 8) recent new issuance, 9) comparative bond analysis, and 10) an illiquidity premium. Equities As of December 31, 2017 (Successor Company), the Company held approximately $65.5 million of equity securities classified as Level 2 and Level 3. Of this total, $65.5 million represents FHLB stock. The Company believes that the cost of the FHLB stock approximates fair value. Other Long-Term Investments and Other Liabilities Other long-term investments and other liabilities consist entirely of free-standing and embedded derivative financial instruments. Refer to Note 7, Derivative Financial Instruments for additional information related to derivatives. Derivative financial instruments are valued using exchange prices, independent broker quotations, or pricing valuation models, which utilize market data inputs. Excluding embedded derivatives, as of December 31, 2017 (Successor Company), 81.2% of derivatives based upon notional values were priced using exchange prices or independent broker quotations. Inputs used to value derivatives include, but are not limited to, interest swap rates, credit spreads, interest rate and equity market volatility indices, equity index levels, and treasury rates. The Company performs monthly analysis on derivative valuations that includes both quantitative and qualitative analyses. Derivative instruments classified as Level 1 generally include futures and options, which are traded on active exchange markets. Derivative instruments classified as Level 2 primarily include swaps, options, and swaptions, which are traded over-the-counter. Level 2 also includes certain centrally cleared derivatives. These derivative valuations are determined using independent broker quotations, which are corroborated with observable market inputs. Derivative instruments classified as Level 3 were embedded derivatives and include at least one significant non-observable input. A derivative instrument containing Level 1 and Level 2 inputs will be classified as a Level 3 financial instrument in its entirety if it has at least one significant Level 3 input. The Company utilizes derivative instruments to manage the risk associated with certain assets and liabilities. However, the derivative instruments may not be classified within the same fair value hierarchy level as the associated assets and liabilities. Therefore, the changes in fair value on derivatives reported in Level 3 may not reflect the offsetting impact of the changes in fair value of the associated assets and liabilities. The embedded derivatives are carried at fair value in other long-term investments and other liabilities on the Company's consolidated balance sheet. The changes in fair value are recorded in earnings as "Realized investment gains (losses)—Derivative financial instruments". Refer to Note 7, Derivative Financial Instruments for more information related to each embedded derivatives gains and losses. The fair value of the GLWB embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using multiple risk neutral stochastic equity scenarios and policyholder behavior assumptions. The risk neutral scenarios are generated using the current swap curve and projected equity volatilities and correlations. The projected equity volatilities are based on a blend of historical volatility and near- term equity market implied volatilities. The equity correlations are based on historical price observations. For policyholder behavior assumptions, expected lapse and utilization assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the Ruark 2015 ALB table with attained age factors varying from 91.1% - 106.6% . The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR plus a credit spread (to represent the Company's non-performance risk). As a result of using significant unobservable inputs, the GLWB embedded derivative is categorized as Level 3. These assumptions are reviewed on a quarterly basis. The balance of the FIA embedded derivative is impacted by policyholder cash flows associated with the FIA product that are allocated to the embedded derivative in addition to changes in the fair value of the embedded derivative during the reporting period. The fair value of the FIA embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using current index values and volatility, the hedge budget used to price the product, and policyholder assumptions (both elective and non-elective). For policyholder behavior assumptions , expected lapse and withdrawal assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the 1994 Variable Annuity MGDB mortality table modified with company experience, with attained age factors varying from 46% - 113% . The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR up to one year and constant maturity treasury rates plus a credit spread (to represent the Company's non-performance risk) thereafter. Policyholder assum ptions are reviewed on an annual basis. As a result of using significant unobservable inputs, the FIA embedded derivative is categorized as Level 3. The balance of the indexed universal life (“IUL”) embedded derivative is impacted by policyholder cash flows associated with the IUL product that are allocated to the embedded derivative in addition to changes in the fair value of the embedded derivative during the reporting period. The fair value of the IUL embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using current index values and volatility, the hedge budget used to price the product, and policyholder assumptions (both elective and non-elective). For policyholder behavior assumptions, expected lapse and withdrawal assumptions are used and updated for actual experience, as necessary. The Company assumes age-ba sed mortality from the SOA 2015 VBT Primary Tables modified with company experience, with attained age factors varying from 34% - 152% . The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR up to one year and constant maturity treasury rates plus a credit spread (to represent the Company's non-performance risk) thereafte r. Policyholder assumptions are reviewed on an annual basis. As a result of using significant unobservable inputs, the IUL embedded derivative is categorized as Level 3. The Company has assumed and ceded certain blocks of policies under modified coinsurance agreements in which the investment results of the underlying portfolios inure directly to the reinsurers. As a result, these agreements contain embedded derivatives that are reported at fair value. Changes in their fair value are reported in earnings. The investments supporting these agreements are designated as "trading securities"; therefore changes in their fair value are also reported in earnings. As of December 31, 2017 (Successor Company), the fair value of the embedded derivative is based upon the relationship between the statutory policy liabilities (net of policy loans) of $2.4 billion and the statutory unrealized gain (loss) of the securities of $226.6 million . As a result, changes in the fair value of the embedded derivatives are largely offset by the changes in fair value of the related investments and each are reported in earnings. The fair value of the embedded derivative is considered a Level 3 valuation due to the unobservable nature of the policy liabilities. Certain of the Company’s subsidiaries have entered into interest support, yearly renewable term (“YRT”) premium support, and portfolio maintenance agreements with PLC. These agreements meet the definition of a derivative and are accounted for at fair value and are considered Level 3 valuations. The fair value of these derivatives as of December 31, 2017 (Successor Company), was $91.6 million and is included in Other long-term investments . For information regarding realized gains on these derivatives please refer to Note 7, Derivative Financial Instruments . The Interest Support Agreement provides that PLC will make payments to Golden Gate II if actual investment income on certain of Golden Gate II’s asset portfolios falls below a calculated investment income amount as defined in the Interest Support Agreement. The calculated investment income amount is a level of investment income deemed to be sufficient to support certain of Golden Gate II’s obligations under a reinsurance agreement with the Company, dated July 1, 2007. The derivative is valued using an internal valuation model that assumes a conservative projection of investment income under an adverse interest rate scenario and the probability that the expectation falls below the calculated investment income amount. This derivative had a fair value of $38.5 million as of December 31, 2017 (Successor Company), however, interest support agreement obligations to Golden Gate II of approximately $2.8 million have been collateralized by PLC. Re-evaluation, if necessary, adjustments of any support agreement collateralization amounts occur annually during the first quarter pursuant to the terms of the support agreement. As of December 31, 2017 (Successor Company), no payments have been triggered under this agreement. The YRT Premium support agreements provide that PLC will make payments to Golden Gate and Golden Gate II in the event that YRT premium rates increase. The derivatives are valued using an internal valuation model. The valuation model is a probability weighted discounted cash flow model. The value is primarily a function of the likelihood and severity of future YRT premium increases. The fair value of these derivatives as of December 31, 2017 (Successor Company), was $48.6 million . As of December 31, 2017 (Successor Company), no payments have been triggered under this agr eement. The portfolio maintenance agreements provide that PLC will make payments to Golden Gate, Golden Gate V, and WCL in the event of other-than-temporary impairments on investments that exceed defined thresholds. The derivatives are valued using an internal discounted cash flow model. The significant unobservable inputs are the projected probability and severity of credit losses used to project future cash flows on the investment portfolios. The fair value of the portfolio maintenance agreements as of December 31, 2017 (Successor Company), was $4.5 million . As of December 31, 2017 (Successor Company), no payments have been triggered under this agreement. The Funds Withheld derivative results from a reinsurance agreement with Shades Creek where the economic performance of certain hedging instruments held by the Company is ceded to Shades Creek. The value of the Funds Withheld derivative is directly tied to the value of the hedging instruments held in the funds withheld account. The hedging instruments predominantly consist of derivative instruments the fair values of which are classified as a Level 2 measurement; as such, the fair value of the Funds Withheld derivative has been classified as a Level 2 measurement. The fair value of the Funds Withheld derivative as of December 31, 2017 (Successor Company), was a liability of $61.7 million . Annuity Account Balances The Company records a certain legacy block of FIA reserves at fair value. Based on the characteristics of these reserves, the Company believes that the fund value approximates fair value. The fair value measurement of these reserves is considered a Level 3 valuation due to the unobservable nature of the fund values. The Level 3 fair value as of December 31, 2017 (Successor Company) is $83.5 million . Separate Accounts Separate account assets are invested in open-ended mutual funds and are included in Level 1. Valuation of Level 3 Financial Instruments The following table presents the valuation method for material financial instruments included in Level 3, as well as the unobservable inputs used in the valuation of those financial instruments: Successor Company Fair Value As of December 31, 2017 Valuation Technique Unobservable Input Range (Weighted Average) (Dollars In Thousands) Assets: Other asset-backed securities $ 504,228 Liquidation Liquidation value $90 - $97 ($94.91) Discounted cash flow Liquidity premium 0.06% - 1.17% (0.75%) Paydown Rate 11.31% - 11.97% (11.54%) Corporate securities 617,770 Discounted cash flow Spread over treasury 0.81% - 3.95% (1.06%) Liabilities: (1) Embedded derivatives—GLWB (2) $ 15,554 Actuarial cash flow model Mortality 91.1% to 106.6% of Lapse 1.0% - 30.0%, depending on product/duration/funded status of guarantee Utilization 99%. 10% of policies have a one-time over-utilization of 400% Nonperformance risk 0.11% - 0.79% Embedded derivative—FIA 218,676 Actuarial cash flow model Expenses $146 per policy Withdrawal rate 1.5% prior to age 70, 100% of the RMD for ages 70+ Mortality 1994 MGDB table with company experience Lapse 1.0% - 30.0%, depending on duration/surrender charge period Nonperformance risk 0.11% - 0.79% Embedded derivative—IUL 80,212 Actuarial cash flow model Mortality 34% - 152% of 2015 Lapse 0.5% - 10%, depending on duration/distribution channel and smoking class Nonperformance risk 0.11% - 0.79% (1) Excludes modified coinsurance arrangements. (2) The fair value for the GLWB embedded derivative is presented as a net liability. The chart above excludes Level 3 financial instruments that are valued using broker quotes and those which book value approximates fair value. The Company has considered all reasonably available quantitative inputs as of December 31, 2017 (Successor Company), but the valuation techniques and inputs used by some brokers in pricing certain financial instruments are not shared with the Company. This resulted in $50.0 million of financial instruments being classified as Level 3 as of December 31, 2017 (Successor Company). Of the $50.0 million , $35.4 million are other asset-backed securities, and $14.6 million are corporate securities. In certain cases the Company has determined that book value materially approximates fair value. As of December 31, 2017 (Successor Company), the Company held $65.5 million of financial instruments where book value approximates fair value which are predominantly FHLB stock. The following table presents the valuation method for material financial instruments included in Level 3, as well as the unobservable inputs used in the valuation of those financial instruments: Successor Company Fair Value As of December 31, 2016 Valuation Technique Unobservable Input Range (Weighted Average) (Dollars In Thousands) Assets: Other asset-backed securities $ 553,308 Discounted cash flow Liquidity value $88 - $97.25 ($95.04) Corporate securities 638,279 Discounted cash flow Spread over treasury 0.31% - 4.50

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Types of Derivative Instruments and Derivative Strategies The Company utilizes a risk management strategy that incorporates the use of derivative financial instruments to reduce exposure to certain risks, including but not limited to, interest rate risk, currency exchange risk, volatility risk, and equity market risk. These strategies are developed through the Company's analysis of data from financial simulation models and other internal and industry sources, and are then incorporated into the Company's risk management program. Derivative instruments expose the Company to credit and market risk and could result in material changes from period to period. The Company attempts to minimize its credit risk by entering into transactions with highly rated counterparties. The Company manages the market risk by establishing and monitoring limits as to the types and degrees of risk that may be undertaken. The Company monitors its use of derivatives in connection with its overall asset/liability management programs and risk management strategies. In addition, all derivative programs are monitored by our risk management department. Derivatives Related to Interest Rate Risk Management Derivative instruments that are used as part of the Company's interest rate risk management strategy include interest rate swaps, interest rate futures, interest rate caps, and interest rate swaptions. Derivatives Related to Foreign Currency Exchange Risk Management Derivative instruments that are used as part of the Company’s foreign currency exchange risk management strategy include foreign currency swaps, foreign currency futures, foreign equity futures, and foreign equity options. Derivatives Related to Risk Mitigation of Certain Annuity Contracts The Company may use the following types of derivative contracts to mitigate its exposure to certain guaranteed benefits related to VA contracts and fixed indexed annuities: • Foreign Currency Futures • Variance Swaps • Interest Rate Futures • Equity Options • Equity Futures • Credit derivatives • Interest Rate Swaps • Interest Rate Swaptions • Volatility Futures • Volatility Options • Funds Withheld Agreement • Total Return Swaps Other Derivatives The Company and certain of its subsidiaries have derivatives with PLC. These derivatives consist of an interest support agreement, YRT premium support agreements, and portfolio maintenance agreements with PLC. The Company has a funds withheld account that consists of various derivative instruments held by us that is used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument. Accounting for Derivative Instruments The Company records its derivative financial instruments in the consolidated balance sheet in "other long-term investments" and "other liabilities" in accordance with GAAP, which requires that all derivative instruments be recognized in the balance sheet at fair value. The change in the fair value of derivative financial instruments is reported either in the statement of income or in other comprehensive income (loss), depending upon whether it qualified for and also has been properly identified as being part of a hedging relationship, and also on the type of hedging relationship that exists. For a derivative financial instrument to be accounted for as an accounting hedge, it must be identified and documented as such on the date of designation. For cash flow hedges, the effective portion of their realized gain or loss is reported as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain attributable to the hedged risk of the hedged item is recognized in current earnings. Effectiveness of the Company's hedge relationships is assessed on a quarterly basis. The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship through earnings in the period of change. Changes in the fair value of derivatives that are recognized in current earnings are reported in "Realized investment gains (losses)—Derivative financial instruments". Derivative Instruments Designated and Qualifying as Hedging Instruments Cash-Flow Hedges • To hedge a fixed rate note denominated in a foreign currency, the Company entered into a fixed-to-fixed foreign currency swap in order to hedge the foreign currency exchange risk associated with the note. The cash flows received on the swap are identical to the cash flow paid on the note. Derivative Instruments Not Designated and Not Qualifying as Hedging Instruments The Company uses various other derivative instruments for risk management purposes that do not qualify for hedge accounting treatment. Changes in the fair value of these derivatives are recognized in earnings during the period of change. Derivatives Related to Variable Annuity Contracts • The Company uses equity futures, equity options, total return swaps, interest rate futures, interest rate swaps, interest rate swaptions, currency futures, volatility futures, volatility options, and variance swaps to mitigate the risk related to certain guaranteed minimum benefits, including GLWB, within its VA products. In general, the cost of such benefits varies with the level of equity and interest rate markets, foreign currency levels, and overall volatility. • The Company markets certain VA products with a GLWB rider. The GLWB component is considered an embedded derivative, not considered to be clearly and closely related to the host contract. • The Company has a funds withheld account that consists of various derivative instruments held by the Company that are used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument. Derivatives Related to Fixed Annuity Contracts • The Company uses equity futures and options to mitigate the risk within its fixed indexed annuity products. In general, the cost of such benefits varies with the level of equity and overall volatility. • The Company markets certain fixed indexed annuity products. The FIA component is considered an embedded derivative, not considered to be clearly and closely related to the host contract. Derivatives Related to Indexed Universal Life Contracts • The Company uses equity futures and options to mitigate the risk within its indexed universal life products. In general, the cost of such benefits varies with the level of equity markets. • The Company markets certain IUL products. The IUL component is considered an embedded derivative, not considered to be clearly and closely related to the host contract. Other Derivatives • The Company and certain of its subsidiaries have an interest support agreement, YRT premium support agreements, and portfolio maintenance agreements with PLC. • The Company uses various swaps and other types of derivatives to manage risk related to other exposures. • The Company is involved in various modified coinsurance arrangements which contain embedded derivatives. Changes in their fair value are recorded in current period earnings. The investment portfolios that support the related modified coinsurance reserves had fair value changes which substantially offset the gains or losses on these embedded derivatives.

Offsetting [Abstract]
OFFSETTING OF ASSETS AND LIABILITIES	OFFSETTING OF ASSETS AND LIABILITIES Certain of the Company’s derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Company and a counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements associated with each master netting arrangement provide that the Company will receive or pledge financial collateral in the event either minimum thresholds, or in certain cases ratings levels, have been reached. Additionally, certain of the Company’s repurchase agreements provide for net settlement on termination of the agreement. Refer to Note 14, Debt and Other Obligations for details of the Company’s repurchase agreement programs.

Mortgage Loans [Abstract]
MORTGAGE LOANS	MORTGAGE LOANS Mortgage Loans The Company invests a portion of its investment portfolio in commercial mortgage loans. As of December 31, 2017 (Successor Company), the Company's mortgage loan holdings were approximately $6.8 billion . The Company has specialized in making loans on credit-oriented commercial properties, credit-anchored strip shopping centers, senior living facilities, and apartments. The Company’s underwriting procedures relative to its commercial loan portfolio are based, in the Company’s view, on a conservative and disciplined approach. The Company concentrates on a small number of commercial real estate asset types associated with the necessities of life (retail, multi-family, senior living, professional office buildings, and warehouses). The Company believes that these asset types tend to weather economic downturns better than other commercial asset classes in which it has chosen not to participate. The Company believes this disciplined approach has helped to maintain a relatively low delinquency and foreclosure rate throughout its history. The majority of the Company's mortgage loans portfolio was underwritten by the Company. From time to time, the Company may acquire loans in conjunction with an acquisition. The Company's commercial mortgage loans are stated at unpaid principal balance, adjusted for any unamortized premium or discount, and net of valuation allowances. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Amortization of premiums and discounts is recorded using the effective yield method. Interest income, amortization of premiums and discounts and prepayment fees are reported in net investment income. As of February 1, 2015, all mortgage loans were measured at fair value. Each mortgage loan was individually analyzed to determine the fair value. Each loan was either analyzed and assigned a discount rate or given an impairment, based on whether facts and circumstances which, as of the acquisition date, indicated less than full projected collections of contractual principal and interest payments. Various market factors were considered in determining the net present value of the expected cash flow stream or underlying real estate collateral, including the characteristics of the borrower, the underlying collateral, underlying credit worthiness of the tenants, and tenant payment history. Known events and risks, such as refinancing risks, were also considered in the fair value determination. In certain cases, fair value was based on the NPV of the expected cash flow stream or the underlying value of the real estate collateral. The following table includes a breakdown of the Company’s commercial mortgage loan portfolio by property type as of December 31, 2017 (Successor Company): Type Percentage of Mortgage Loans on Real Estate Retail 52.1 % Office Buildings 10.9 Apartments 8.8 Warehouses 10.4 Senior housing 13.7 Other 4.1 100.0 % The Company specializes in originating mortgage loans on either credit-oriented or credit-anchored commercial properties. No single tenant’s exposure represents more than 1.5% of mortgage loans. Approximately 64.4% of the mortgage loans are on properties located in the following states: State Percentage of Mortgage Loans on Real Estate Alabama 9.6 % Florida 9.4 Texas 8.4 Georgia 7.9 Ohio 5.5 Tennessee 5.3 California 5.2 South Carolina 3.3 North Carolina 4.9 Utah 4.9 64.4 % During the year ended December 31, 2017 (Successor Company), the Company funded approximately $1.6 billion of new loans, with an average loan size of $8.8 million . The average size mortgage loan in the portfolio as of December 31, 2017 (Successor Company), was $4.0 million and the weighted-average interest rate was 4.8% . The largest single mortgage loan at December 31, 2017 (Successor Company) was $61.1 million . Certain of the mortgage loans have call options that occur within the next 11 years . However, if interest rates were to significantly increase, we may be unable to exercise the call options on our existing mortgage loans commensurate with the significantly inc reased market rates . Assuming the loans are called at their next call dates, approximately $161.2 million would become due in 2018 , $858.6 million in 2019 through 2023 , $105.8 million in 2024 through 2028 , and $2.0 million thereafter. The Company offers a type of commercial mortgage loan under which the Company will permit a loan-to-value ratio of up to 85% in exchange for a participating interest in the cash flows from the underlying real estate. As of December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), approximately $669.3 million and $595.2 million , respectively, of the Company’s mortgage loans have this participation feature. Cash flows received as a result of this participation feature are recorded as interest income when received. During the year ended December 31, 2017 (Successor Company), the year ended December 31, 2016 (Successor Company), the period of February 1, 2015 to December 31, 2015 (Successor Company), and the period of January 1, 2015 to January 31, 2015 (Predecessor Company), the Company recognized $37.2 million , $16.7 million , $29.8 million , and $0.1 million of participating mortgage loan income, respectively. As of December 31, 2017 (Successor Company), approximately $6.5 million of invested assets consisted of nonperforming mortgage loans, restructured mortgage loans, or mortgage loans that were foreclosed and were converted to real estate properties. The Company does not expect these investments to adversely affect its liquidity or ability to maintain proper matching of assets and liabilities. During the year ended December 31, 2017 (Successor Company), certain mortgage loan transactions occurred that were accounted for as troubled debt restructurings. For all mortgage loans, the impact of troubled debt restructurings is generally reflected in our investment balance and in the allowance for mortgage loan credit losses. During the year ended December 31, 2017 (Successor Company), the Company recognized two troubled debt restructuring transactions as a result of the Company granting a concession to a borrower which included loan terms unavailable from other lenders. These concessions were the result of agreements between the creditor and the debtor. The Company did not identify any loans whose principal was permanently impaired during the year ended December 31, 2017 (Successor Company). As of December 31, 2016 (Successor Company), approximately $1.5 million of invested assets consisted of nonperforming, restructured, or mortgage loans that were foreclosed and were converted to real estate properties. The Company does not expect these investments to adversely affect its liquidity or ability to maintain proper matching of assets and liabilities. During the year ended December 31, 2016 (Successor Company), certain mortgage loan transactions occurred that were accounted for as troubled debt restructurings. For all mortgage loans, the impact of troubled debt restructurings is generally reflected in our investment balance and in the allowance for mortgage loan credit losses. During the year ended December 31, 2016 (Successor Company), the Company recognized a troubled debt restructuring as a result of the Company granting a concession to a borrower which included loan terms unavailable from other lenders and reduced the expected cash flows on the loan. This concession was the result of agreements between the creditor and the debtor. The Company did not identify any loans whose principal was permanently impaired during the year ended December 31, 2016 (Successor Company). As of December 31, 2015 (Successor Company), approximately $4.7 million of invested assets consisted of nonperforming, restructured, or mortgage loans that were foreclosed and were converted to real estate properties since February 1, 2015 (Successor Company). The Company does not expect these investments to adversely affect its liquidity or ability to maintain proper matching of assets and liabilities. During the period of February 1, 2015 to December 31, 2015 (Successor Company) and the period of January 1, 2015 to January 31, 2015 (Predecessor Company), the Company entered into certain mortgage loan transactions that were accounted for as troubled debt restructurings. For all mortgage loans, the impact of troubled debt restructurings is generally reflected in the Company's investment balance and in the allowance for mortgage loan credit losses. Transactions accounted for as troubled debt restructurings during the period of February 1, 2015 to December 31, 2015 (Successor Company) and the period of January 1, 2015 to January 31, 2015 (Predecessor Company) included either the acceptance of assets in satisfaction of principal during the respective periods or at a future date and were the result of agreements between the creditor and the debtor. During the period of February 1, 2015 to December 31, 2015 (Successor Company), the Company accepted or agreed to accept assets of $15.8 million in satisfaction of $21.1 million of principal and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), the Company accepted or agreed to accept assets of $11.3 million in satisfaction of $13.8 million of principal. Of the amounts accepted or agreed to accept in satisfaction of principal during the period of February 1, 2015 to December 31, 2015 (Successor Company) $3.7 million related to foreclosures. These transactions resulted in no material realized losses in the Company's investment in mortgage loans net of existing discounts for mortgage loan losses for the period of February 1, 2015 to December 31, 2015 (Successor Company). The Company’s mortgage loan portfolio consists of two categories of loans: 1) those not subject to a pooling and servicing agreement and 2) those subject to a contractual pooling and servicing agreement. As of December 31, 2017 (Successor Company), $6.5 million of mortgage loans not subject to a pooling and servicing agreement were nonperforming, restructured, or mortgage loans that were foreclosed and were converted to real estate. None of the restructured loans were nonperforming during the year ended December 31, 2017 (Successor Company). The Company foreclosed on $6.1 million of nonperforming loans during the year ended December 31, 2017 (Successor Company). As of December 31, 2017 (Successor Company), none of the loans subject to a pooling and servicing agreement were nonperforming or restructured. The Company did no t foreclose on any nonperforming loans subject to a pooling and servicing agreement during the year ended December 31, 2017 (Successor Com pany). As of December 31, 2017 (Successor Company), there were no allowances for mortgage loan credit losses and as of December 31, 2016 (Successor Company), there was a $0.7 million allowance for mortgage loan credit losses. Due to the Company’s loss experience and nature of the loan portfolio, the Company believes that a collectively evaluated allowance would be inappropriate. The Company believes an allowance calculated through an analysis of specific loans that are believed to have a higher risk of credit impairment provides a more accurate presentation of expected losses in the portfolio and is consistent with the applicable guidance for loan impairments in ASC Subtopic 310. Since the Company uses the specific identification method for calculating the allowance, it is necessary to review the economic situation of each borrower to determine those that have higher risk of credit impairment. The Company has a team of professionals that monitors borrower conditions such as payment practices, borrower credit, operating performance, and property conditions, as well as ensuring the timely payment of property taxes and insurance. Through this monitoring process, the Company assesses the risk of each loan. When issues are identified, the severity of the issues are assessed and reviewed for possible credit impairment. If a loss is probable, an expected loss calculation is performed and an allowance is established for that loan based on the expected loss. The expected loss is calculated as the excess carrying value of a loan over either the present value of expected future cash flows discounted at the loan’s original effective interest rate, or the current estimated fair value of the loan’s underlying collateral. A loan may be subsequently charged off at such point that the Company no longer expects to receive cash payments, the present value of future expected payments of the renegotiated loan is less than the current principal balance, or at such time that the Company is party to foreclosure or bankruptcy proceedings associated with the borrower and does not expect to recover the principal balance of the loan. A charge off is recorded by eliminating the allowance against the mortgage loan and recording the renegotiated loan or the collateral property related to the loan as investment real estate on the balance sheet, which is carried at the lower of the appraised fair value of the property or the unpaid principal balance of the loan, less estimated selling costs associated with the property: Successor Company As of As of (Dollars In Thousands) Beginning balance $ 724 $ — Charge offs (6,708 ) (4,682 ) Recoveries (731 ) — Provision 6,715 5,406 Ending balance $ — $ 724 It is the Company's policy to cease accruing interest on loans that are over 90 days delinquent. For loans less than 90 days delinquent, interest is accrued unless it is determined that the accrued interest is not collectible. If a loan becomes over 90 days delinquent, it is the Company’s general policy to initiate foreclosure proceedings unless a workout arrangement to bring the loan current is in place. For loans subject to a pooling and servicing agreement, there are certain additional restrictions and/or requirements related to workout proceedings, and as such, these loans may have different attributes and/or circumstances affecting the status of delinquency or categorization of those in nonperforming status. An analysis of the delinquent loans is shown in the following chart: 30-59 Days Delinquent 60-89 Days Delinquent Greater than 90 Days Delinquent Total Delinquent (Dollars In Thousands) Successor Company As of December 31, 2017 Commercial mortgage loans $ 1,817 $ — $ — $ 1,817 Number of delinquent commercial mortgage loans 2 — — 2 As of December 31, 2016 Commercial mortgage loans $ 3,669 $ — $ — $ 3,669 Number of delinquent commercial mortgage loans 4 — — 4 The Company’s commercial mortgage loan portfolio consists of mortgage loans that are collateralized by real estate. Due to the collateralized nature of the loans, any assessment of impairment and ultimate loss given a default on the loans is based upon a consideration of the estimated fair value of the real estate. The Company limits accrued interest income on impaired loans to ninety days of interest. Once accrued interest on the impaired loan is received, interest income is recognized on a cash basis.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL	GOODWILL During the fourth quarter of 2017, the Company performed its annual qualitative evaluation of goodwill based on the circumstances that existed as of October 1, 2017 (Successor Company) and determined that there was no indication that its segment goodwill was more likely than not impaired, thus no quantitative assessment was performed and no adjustment to impair goodwill was necessary. The Company has assessed whether events have occurred subsequent to October 1, 2017 that would impact the Company's conclusion and no such events were identified. As part of the Company's ongoing assessment of goodwill recoverability, the impact of The Tax Reform Act and the impact that the lower corporate tax rate would have on the carrying value of the reporting units and their associated fair values was assessed in response to potential considerations as outlined under ASC 350-20-35-3C. After consideration of applicable factors and circumstances noted as part of a qualitative assessment, the Company determined that it was more likely than not that the increase in the fair value of the reporting unit would exceed the increase in the carrying value of the reporting units and thus did not consider this to be a triggering event that would require a quantitative assessment of impairment . As of December 31, 2016 (Successor Company), the Company increased its goodwill balance by approximately $61.0 million in the Asset Protection segment, which was attributed to the US Warranty acquisition. Refer to Note 3, Significant Transactions . The balance of goodwill for the Company as of December 31, 2017 (Successor Company) was $793.5 million .

CERTAIN NONTRADITIONAL LONG-DURATION CONTRACTS
CERTAIN NONTRADITIONAL LONG-DURATION CONTRACTS	CERTAIN NONTRADITIONAL LONG-DURATION CONTRACTS The Company issues variable universal life and VA products through its separate accounts for which investment income and investment gains and losses accrue directly to, and investment risk is borne by, the contract holder. The Company also offers, for our VA products, certain GMDB. The most significant of these guarantees involve 1) return of the highest anniversary date account value, or 2) return of the greater of the highest anniversary date account value or the last anniversary date account value compounded at 5% interest or 3) return of premium. The GLWB rider provides the contract holder with protection against certain adverse market impacts on the amount they can withdraw and is classified as an embedded derivative and is carried at fair value on the Company's balance sheet. The VA separate account balances subject to GLWB were $9.7 billion as of December 31, 2017 (Successor Company). For more information regarding the valuation of and income impact of GLWB, please refer to Note 2, Summary of Significant Accounting Policies , Note 6, Fair Value of Financial Instruments , and Note 7, Derivative Financial Instruments . The GMDB reserve is calculated by applying a benefit ratio, equal to the present value of total expected GMDB claims divided by the present value of total expected contract assessments, to cumulative contract assessments. This amount is then adjusted by the amount of cumulative GMDB claims paid and accrued interest. Assumptions used in the calculation of the GMDB reserve were as follows: mean investment performance of 7.01% , age-based mortality from the Ruark 2015 ALB table adjusted for company and industry experience, lapse rates determined by a dynamic formula, and an average discount rate of 4.9% . Changes in the GMDB reserve are included in benefits and settlement expenses in the accompanying consolidated statements of income. The VA separate account balances subject to GMDB were $13.1 billion as of December 31, 2017 (Successor Company).

REINSURANCE	SIGNIFICANT TRANSACTIONS Reinsurance and Financing Transactions On January 15, 2016, PLC and the Company completed the transaction contemplated by the Master Agreement, dated September 30, 2015 (the “Master Agreement”), with Genworth Life and Annuity Insurance Company (“GLAIC”). Pursuant to the Master Agreement, effective January 1, 2016, the Company entered into a reinsurance agreement (the “Reinsurance Agreement”) under the terms of which the Company coinsures certain term life insurance business of GLAIC (the “GLAIC Block”). In connection with the reinsurance transaction, on January 15, 2016, Golden Gate Captive Insurance Company (“Golden Gate”), a wholly owned subsidiary of the Company, and Steel City, LLC (“Steel City”), a newly formed wholly owned subsidiary of PLC, entered into an 18 -year transaction to finance $2.188 billion of “XXX” reserves related to the acquired GLAIC Block and the other term life insurance business reinsured to Golden Gate by the Company and West Coast Life Insurance Company (“WCL”), a direct wholly owned subsidiary of the Company. Steel City issued notes with an aggregate initial principal amount of $2.188 billion to Golden Gate in exchange for a surplus note issued by Golden Gate with an initial principal amount of $2.188 billion . Through the structure, Hannover Life Reassurance Company of America (Bermuda) Ltd., The Canada Life Assurance Company (Barbados Branch) and Nomura Americas Re Ltd. (collectively, the “Risk-Takers”) provide credit enhancement to the Steel City notes for the 18 -year term in exchange for credit enhancement fees. The transaction is “non-recourse” to PLC, WCL and the Company, meaning that none of these companies are liable to reimburse the Risk-Takers for any credit enhancement payments required to be made. In connection with the transaction, PLC has entered into certain support agreements under which it guarantees or otherwise supports certain obligations of Golden Gate or Steel City, including a guarantee of the fees to the Risk-Takers. As a result of the financing transaction described above, the $800 million of Golden Gate Series A Surplus Notes held by PLC were contributed to the Company and then subsequently contributed to Golden Gate, which resulted in the extinguishment of these notes. Also on January 15, 2016, Golden Gate paid an extraordinary dividend of $300 million to the Company as approved by the Vermont Department of Financial Regulation. The transactions described above resulted in an increase to total assets and total liabilities of approximately $2.8 billion . Of the approximate $2.8 billion increase in total assets, $0.6 billion was the result of the reinsurance transaction with GLAIC which included a $280 million increase in VOBA. The remaining $2.2 billion increase to total assets and liabilities is associated with the financing transaction between Golden Gate and Steel City. The Company considered whether the Reinsurance Agreement constituted the purchase of a business for accounting and reporting purposes pursuant to ASC 805, Business Combinations. While the transaction included a continuation of the certain revenue-producing activities associated with the reinsured policies, it did not result in the acquisition of a market distribution system, sales force or production techniques. Based on Management’s decision not to pursue distribution opportunities or future sales related to the reinsured policies, the Company accounted for the transaction as a reinsurance agreement under ASC 944, Insurance Contracts and asset acquisition under ASC 805. Accordingly, the Company recorded the assets and liabilities acquired under the reinsurance agreement at fair value and recognized an intangible asset, VOBA, equal to the excess of the fair value of assets acquired over liabilities assumed, measured in accordance with the Company's accounting policies for insurance and reinsurance contracts that it issues or holds pursuant to ASC 944. USWC Holding Company Acquisition On December 1, 2016, the Company completed the acquisition of the Pompano Beach, Florida-based USWC Holding Company (“US Warranty”) pursuant to a Stock Purchase Agreement. US Warranty's primary operating subsidiary is United States Warranty Corp., which currently markets vehicle service contracts, GAP coverage, and a suite of ancillary automotive maintenance and protection products nationwide. This acquisition has provided the Company's Asset Protection segment and USWC with expanded market reach, enhanced product and operational capabilities, and higher collective growth potential. The transaction was accounted for under the acquisition method of accounting under ASC Topic 805. In accordance with ASC Topic 805-20-30, all identifiable assets acquired and liabilities assumed were measured at fair value as of the acquisition date. On the acquisition date, goodwill of $61.0 million represented the cost in excess of the fair value of net assets acquired (including identifiable intangibles), and reflected the US Warranty's assembled workforce, future growth potential and other sources of value not associated with identifiable assets. The Company acquired 100% of voting equity interests. The aggregate purchase price for US Warranty was $136.1 million . The amount recorded as the value of business acquired at December 1, 2016, represents the actuarially estimated present value of after-tax future cash flows, adjusted for statutory reserve differences and cost of capital, from the policies acquired through the US Warranty acquisition. This amount will be amortized in proportion with the gross premiums or estimated net profits of the acquired insurance contracts. The following table summarizes the fair values of the net assets acquired as of the acquisition date: Fair Value As of December 1, 2016 (Dollars in Thousands) Assets Fixed maturities $ 10,592 Other long-term investments 2,340 Cash 122,167 Accrued investment income 52 Accounts and premiums receivables 18,536 Reinsurance receivable 9,397 Value of businesses acquired 5,079 Goodwill 61,027 Other intangibles 70,400 Property and equipment 390 Accrued income taxes 4,161 Other assets 40 Total assets 304,181 Liabilities Unearned premiums $ 82,757 Other policyholders' funds 21,483 Other liabilities 24,951 Deferred income taxes 38,929 Total liabilities 168,120 Net assets acquired $ 136,061 Intangible assets recognized by the Company included the following (excluding goodwill): Estimated Fair Value on Estimated Acquisition Date Useful Life (Dollars In Thousands) (In Years) Distribution relationships $ 65,000 13-21 Trade names 1,400 5-6 Technology 4,000 8-11 Total intangible assets $ 70,400 Identified intangible assets were valued using the excess earnings method, relief from royalty method or cost approach, as appropriate. Amortizable intangible assets will be amortized straight line over their assigned useful lives. The following is a schedule of future estimated aggregate amortization expense: Year Amount (Dollars In Thousands) 2017 $ 4,843 2018 4,843 2019 4,843 2020 4,843 2021 4,843 The following (unaudited) pro forma condensed consolidated results of operations assumes that the acquisition of US Warranty was completed as of January 1, 2015: Successor Company For The Year Ended December 31, 2016 February 1, 2015 to December 31, 2015 (Dollars In Thousands) Revenue (1) $ 4,342,054 $ 3,530,073 Net income (2) 352,856 179,877 (1) Includes $4.7 million of revenue recognized in the Company's net income for year ended December 31, 2016 (Successor Company). (2) Includes $0.2 million of net income recognized in the Company's net income for the year ended December 31, 2016 (Successor Company). The pro forma information above is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisition been consummated as of that time, not is it intended to be a projection of future results. REINSURANCE The Company reinsures certain of its risks with (cedes), and assumes risks from, other insurers under yearly renewable term, coinsurance, and modified coinsurance agreements. Under yearly renewable term agreements, the Company reinsures only the mortality risk, while under coinsurance the Company reinsures a proportionate share of all risks arising under the reinsured policy. Under coinsurance, the reinsurer receives a proportionate share of the premiums less commissions and is liable for a corresponding share of all benefit payments. Modified coinsurance is accounted for in a manner similar to coinsurance except that the liability for future policy benefits is held by the ceding company, and settlements are made on a net basis between the companies. 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 us under the terms of the reinsurance agreements. The Company monitors the concentration of credit risk the Company has with any reinsurer, as well as the financial condition of its reinsurers. As of December 31, 2017 (Successor Company), the Company had reinsured approximately 38% of the face value of its life insurance in-force. The Company has reinsured approximately 16% of the face value of its life insurance in-force with the following three reinsurers: • Security Life of Denver Insurance Co. (currently administered by Hannover Re) • Swiss Re Life & Health America Inc. • The Lincoln National Life Insurance Co. (currently administered by Swiss Re Life & Health America Inc.) The Company has not experienced any credit losses for the years ended December 31, 2017 (Successor Company), December 31, 2016 (Successor Company), or December 31, 2015 (Successor Company) related to these reinsurers. The Company has set limits on the amount of insurance retained on the life of any one person. The amount of insurance retained by the Company on any one life on traditional life insurance was $500,000 in years prior to mid-2005. In 2005, this retention amount was increased to $1,000,000 for certain policies, and during 2008, it was increased to $2,000,000 for certain policies. During 2016, the retention amount was increased to $5,000,000 . Reinsurance premiums, commissions, expense reimbursements, benefits, and reserves related to reinsured long-duration contracts are accounted for over the life of the underlying reinsured contracts using assumptions consistent with those used to account for the underlying contracts. The cost of reinsurance related to short-duration contracts is accounted for over the reinsurance contract period. Amounts recoverable from reinsurers, for both short- and long-duration reinsurance arrangements, are estimated in a manner consistent with the claim liabilities and policy benefits associated with reinsured policies. The following table presents the net life insurance in-force: Successor Company As of December 31, 2017 2016 (Dollars In Millions) Direct life insurance in-force $ 751,512 $ 739,249 Amounts assumed from other companies 110,205 116,265 Amounts ceded to other companies (328,377 ) (348,995 ) Net life insurance in-force $ 533,340 $ 506,519 Percentage of amount assumed to net 21 % 23 % The following table reflects the effect of reinsurance on life, accident/health, and property and liability insurance premiums written and earned: Gross Amount Ceded to Other Companies Assumed from Other Companies Net Amount (Dollars In Thousands) Successor Company For The Year Ended December 31, 2017 Premiums and policy fees: -1 Life insurance $ 2,655,846 $ (1,230,258 ) $ 435,113 $ 1,860,701 (1) Accident/health insurance 51,991 (33,052 ) 14,946 33,885 Property and liability insurance 288,809 (103,786 ) 9,657 194,680 Total $ 2,996,646 $ (1,367,096 ) $ 459,716 $ 2,089,266 For The Year Ended December 31, 2016 Premiums and policy fees: Life insurance $ 2,610,682 $ (1,207,159 ) $ 454,999 $ 1,858,522 (1) Accident/health insurance 58,076 (36,935 ) 17,439 38,580 Property and liability insurance 242,517 (86,629 ) 5,706 161,594 Total $ 2,911,275 $ (1,330,723 ) $ 478,144 $ 2,058,696 February 1, 2015 to December 31, 2015 Premiums and policy fees: Life insurance $ 2,360,643 $ (1,058,706 ) $ 308,280 $ 1,610,217 (1) Accident/health insurance 70,243 (36,871 ) 18,252 51,624 Property and liability insurance 228,500 (79,294 ) 6,904 156,110 Total $ 2,659,386 $ (1,174,871 ) $ 333,436 $ 1,817,951 Gross Amount Ceded to Other Companies Assumed from Other Companies Net Amount (Dollars In Thousands) Predecessor Company January 1, 2015 to January 31, 2015 Premiums and policy fees: Life insurance $ 204,185 $ (80,657 ) $ 28,601 $ 152,129 (1) Accident/health insurance 6,846 (4,621 ) 1,809 4,034 Property and liability insurance 18,475 (6,354 ) 666 12,787 Total $ 229,506 $ (91,632 ) $ 31,076 $ 168,950 (1) Includes annuity policy fees of $173.5 million , $80.1 million , $77.2 million , and $7.7 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), the periods of February 1, 2015 to December 31, 2015 (Successor Company) and January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. As of December 31, 2017 and 2016 (Successor Company), policy and claim reserves relating to insurance ceded of $4.8 billion and $5.1 billion , respectively, are included in reinsurance receivables. Should any of the reinsurers be unable to meet its obligation at the time of the claim, the Company would be obligated to pay such claims. As of December 31, 2017 and 2016 (Successor Company), the Company had paid $96.6 million and $87.9 million , respectively, of ceded benefits which are recoverable from reinsurers. In addition, as of December 31, 2017 and 2016 (Successor Company), the Company had receivables of $65.1 million and $64.5 million , respectively, related to insurance assumed. The Company’s third party reinsurance receivables amounted to $4.8 billion and $5.1 billion as of December 31, 2017 and 2016 (Successor Company), respectively. These amounts include ceded reserve balances and ceded benefit payments. The ceded benefit payments are recoverable from reinsurers.

In general, the reinsurers' ability to terminate coverage for existing cessions is limited to such circumstances as material breach of contract or non-payment of premiums by the ceding company. The reinsurance contracts generally contain provisions intended to provide the ceding company with the ability to cede future business on a basis consistent with historical terms. However, either party may terminate any of the contracts with respect to future business upon appropriate notice to the other party. Generally, the reinsurance contracts do not limit the overall amount of the loss that can be incurred by the reinsurer. The amount of liabilities ceded under contracts that provide for the payment of experience refunds is immaterial.

The support agreements provide that amounts would become payable by PLC if Golden Gate’s annual general corporate expenses were higher than modeled amounts, certain reinsurance rates applicable to the subject business increase beyond modeled amounts or in the event write-downs due to other-than-temporary impairments on assets held in certain accounts exceed defined threshold levels. Additionally, PLC has entered into a separate agreement to guarantee payment of certain fee amounts in connection with the credit enhancement of the Steel City Notes. As of December 31, 2017 (Successor Company), no payments have been made under these agreements. In connection with the transaction outlined above, Golden Gate had a $2.014 billion outstanding non-recourse funding obligation as of December 31, 2017 (Successor Company). This non-recourse funding obligation matures in 2039 and accrues interest at a fixed annual rate of 4.75% . Golden Gate II Captive Insurance Company Golden Gate II Captive Insurance Company (“Golden Gate II”), a South Carolina special purpose financial captive insurance company and wholly owned subsidiary, had $575 million of non-recourse funding obligations as of December 31, 2017 (Successor Company). These outstanding non-recourse funding obligations were issued to special purpose trusts, which in turn issued securities to third parties. Certain of our affiliates own a portion of these securities. As of December 31, 2017 (Successor Company), securities related to $58.6 million of the balance of the non-recourse funding obligations were held by external parties, securities related to $251.2 million of the non-recourse fun ding obligations were held by nonconsolidated affiliates, and $265.2 million were held by consolidated subsidiaries of the Company. P LC has entered into certain support agreements with Golden Gate II obligating it to make capital contributions or provide support related to certain of Golden Gate II’s expenses and in certain circumstances, to collateralize certain of PLC’s obligations to Golden Gate II. These support agreements provide that amounts would become payable by PLC to Golden Gate II if its annual general corporate expenses were higher than modeled amounts or if Golden Gate II’s investment income on certain investments or premium income was below certain actuarially determined amounts. As of December 31, 2017 (Successor Company), no payments have been made under these agreements; however, certain support agreement obligations to Golden Gate II of approximately $2.8 million have been collateralized by PLC. Re-evaluation and, if necessary, adjustments of any support agreement collateralization amounts occur annually during the first quarter pursuant to the terms of the support agreements. During the year ended December 31, 2017 (Successor Company), the Company and its affiliates did not repurchase any of its outstanding non-recourse funding obligations. During the year ended December 31, 2016 (Successor Company), the Company repurchased $ 86.3 million of its outstanding non-recourse funding obligations, at a discount. Golden Gate V Vermont Captive Insurance Company On October 10, 2012, Golden Gate V Vermont Captive Insurance Company (“Golden Gate V”), a Vermont special purpose financial insurance company and Red Mountain, LLC (“Red Mountain”), both wholly owned subsidiaries, entered into a 20 -year transaction to finance up to $945 million of “AXXX” reserves related to a block of universal life insurance policies with secondary guarantees issued by the Company and its subsidiary, West Coast Life Insurance Company (“WCL”). Golden Gate V issued non-recourse funding obligations to Red Mountain, and Red Mountain issued a note with an initial principal amount of $275 million , increasing to a maximum of $945 million in 2027, to Golden Gate V for deposit to a reinsurance trust supporting Golden Gate V’s obligations under a reinsurance agreement with WCL, pursuant to which WCL cedes liabilities relating to the policies of WCL and retrocedes liabilities relating to the policies of the Company. Through the structure, Hannover Life Reassurance Company of America (“Hannover Re”), the ultimate risk taker in the transaction, provides credit enhancement to the Red Mountain note for the 20 -year term in exchange for a fee. The transaction is “non-recourse” to Golden Gate V, Red Mountain, WCL, PLC, and the Company, meaning that none of these companies are liable for the reimbursement of any credit enhancement payments required to be made. As of December 31, 2017 (Successor Company), the principal balance of the Red Mountain note was $620 million . Future scheduled capital contributions to prefund credit enhancement fees amount to approximately $121.8 million and will be paid in annual installments through 2031. In connection with the transaction, PLC has entered into certain support agreements under which it guarantees or otherwise supports certain obligations of Golden Gate V or Red Mountain. The support agreements provide that amounts would become payable by PLC if Golden Gate V's annual general corporate expenses were higher than modeled amounts or in the event write-downs due to other-than-temporary impairments on assets held in certain accounts exceed defined threshold levels. Additionally, PLC has entered into separate agreements to indemnify Golden Gate V with respect to material adverse changes in non-guaranteed elements of insurance policies reinsured by Golden Gate V and to guarantee payment of certain fee amounts in connection with the credit enhancement of the Red Mountain note. As of December 31, 2017 (Successor Company), no payments have been made under these agreements. In connection with the transaction outlined above, Golden Gate V had a $620 million outstanding non-recourse funding obligation as of December 31, 2017 (Successor Company). This non-recourse funding obligation matures in 2037, has scheduled increases in principal to a maximum of $945 million , and accrues interest at a fixed annual rate of 6.25% .

(3) Fixed rate obligations Letters of Credit Golden Gate III Vermont Captive Insurance Company On April 23, 2010, Golden Gate III Vermont Captive Insurance Company ("Golden Gate III"), a Vermont special purpose financial insurance company and wholly owned subsidiary of PLICO, entered into a Reimbursement Agreement (the "Reimbursement Agreement") with UBS AG, Stamford Branch ("UBS"), as issuing lender. Under the Reimbursement Agreement, UBS issued a letter of credit (the "LOC)") to a trust for the benefit of WCL. The Reimbursement Agreement has undergone three separate amendments and restatements. The Reimbursement Agreement's current effective date is June 25, 2014. The LOC balance reached its scheduled peak of $935 million in 2015. As of December 31, 2017 (Successor Company), the LOC balance was $885 million . The term of the LOC is expected to be approximately 15 years from the original issuance date. This transaction is “non-recourse” to WCL, PLC, and the Company, meaning that none of these companies other than Golden Gate III are liable for reimbursement on a draw of the LOC. PLC has entered into certain support agreements with Gol den Gate III obligating PLC to make capital contributions or provide support related to certain of Golden Gate III’s expenses and in certain circumstances, to collateralize certain of PLC’s obligations to Golden Gate III. Future scheduled capital contributions amount to approximately $70.0 million and will be paid in two installments with the last payment occurring in 2021. These contributions may be subject to potential offset against dividend payments as permitted under the terms of the Reimbursement Agreement. The support agreements provide that amounts would become payable by PLC to Golden Gate III if Golden Gate III’s annual general corporate expenses were higher than modeled amounts or if specified catastrophic losses occur during defined time periods with respect to the policies reinsured by Golden Gate III. Pursuant to the terms of an amended and restated letter agreement with UBS, PLC has continued to guarantee the payment of fees to UBS as specified in the Reimbursement Agreement . As of December 31, 2017 (Successor Company), no payments have been made under these agreements. Golden Gate IV Vermont Captive Insurance Company Golden Gate IV Vermont Captive Insurance Company (“Golden Gate IV”), a Vermont special purpose financial insurance company and wholly owned subsidiary, is party to a Reimbursement Agreement with UBS AG, Stamford Branch, as issuing lender. Under the Reimbursement Agreement, dated December 10, 2010, UBS issued an LOC in the initial amount of $270 million to a trust for the benefit of WCL. Pursuant to the terms of the Reimbursement Agreement, the LOC reached its scheduled peak amount of $790 million in 2016. As of December 31, 2017 (Successor Company), the LOC balance was $785 million .The term of the LOC is expected to be 12 years from the original issuance date (stated maturity of December 30, 2022). The LOC was issued to support certain obligations of Golden Gate IV to WCL under an indemnity reinsurance agreement, pursuant to which WCL cedes liabilities relating to the policies of WCL and retrocedes liabilities relating to the policies of the Company. This transaction is “non-recourse” to WCL, PLC, and the Company, meaning that none of these companies other than Golden Gate IV are liable for reimbursement on a draw of the LOC. PLC has entered into certain support agreements with Golden Gate IV obligating PLC to make capital contributions or provide support related to certain of Golden Gate IV’s expenses and in certain circumstances, to collateralize certain of PLC’s obligations to Golden Gate IV. The support agreements provide that amounts would become payable by PLC to Golden Gate IV if Golden Gate IV’s annual general corporate expenses were higher than modeled amounts or if specified catastrophic losses occur during defined time periods with respect to the policies reinsured by Golden Gate IV. PLC has also entered into a separate agreement to guarantee the payments of LOC fees under the terms of the Reimbursement Agreement . As of December 31, 2017 (Successor Company), no payments have been made under these agreements. Secured Financing Transactions Repurchase Program Borrowings While the Company anticipates that the cash flows of its operating subsidiaries will be sufficient to meet its investment commitments and operating cash needs in a normal credit market environment, the Company recognizes that investment commitments scheduled to be funded may, from time to time, exceed the funds then available. Therefore, the Company has established repurchase agreement programs for certain of its insurance subsidiaries to provide liquidity when needed. The Company expects that the rate received on its investments will equal or exceed its borrowing rate. Under this program, the Company may, from time to time, sell an investment security at a specific price and agree to repurchase that security at another specified price at a later date. These borrowings are typically for a term less than 90 days . The market value of securities to be repurchased is monitored and collateral levels are adjusted where appropriate to protect the counterparty against credit exposure. Cash received is invested in fixed maturity securities, and the agreements provided for net settlement in the event of default or on termination of the agreements . As of December 31, 2017 (Successor Company), the fair value of securities pledged under the repurchase program was $1,006.6 million and the repurchase obligation of $885.0 million was included in the Company’s consolidated balance sheets (at an average borrowing rate of 142 basis points). During the year ended December 31, 2017 (Successor Company), the maximum balance outstanding at any one point in time related to these programs was $988.5 million . The average daily balance was $624.7 million (at an average borrowing rate of 101 basis points) during the year ended December 31, 2017 (Successor Company). During the year ended December 31, 2016 (Successor Company), the maximum balance outstanding at any one point in time related to these programs was $1,065.8 million . The average daily balance was $505.4 million (at an average borrowing rate of 44 basis points) during the year ended December 31, 2016 (Successor Company). Securities Lending The Company participates in securities lending, primarily as an investment yield enhancement, whereby securities that are held as investments are loaned out to third parties for short periods of time. The Company requires initial collateral of 102% of the market value of the loaned securities to be separately maintained. The loaned securities’ market value is monitored on a daily basis. As of December 31, 2017 (Successor Company), securities with a market value of $125.3 million were loaned under this program. As collateral for the loaned securities, the Company receives short-term investments, which are recorded in “short-term investments” with a corresponding liability recorded in “secured financing liabilities” to account for its obligation to return the collateral. As of December 31, 2017 (Successor Company), the fair value of the collateral related to this program was $132.7 million and the Company has an obligation to return $132.7 million of collateral to the securities borrowers.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company leases administrative and marketing office space in approximately 16 cities (excluding the home office building), with most leases being for periods of three to ten years .

Under the insurance guaranty fund laws in most states, insurance companies doing business therein can be assessed up to prescribed limits for policyholder losses incurred by insolvent companies. From time to time, companies may be asked to contribute amounts beyond prescribed limits. It is possible that the Company could be assessed with respect to product lines not offered by the Company. In addition, legislation may be introduced in various states with respect to guaranty fund assessment laws related to insurance products, including long term care insurance and other specialty products, that increases the cost of future assessments or alters future premium tax offsets received in connection with guaranty fund assessments. The Company cannot predict the amount, nature or timing of any future assessments or legislation, any of which could have a material and adverse impact on the Company's financial condition or results of operations. A number of civil jury verdicts have been returned against insurers, broker dealers and other providers of financial services involving sales, refund or claims practices, alleged agent misconduct, failure to properly supervise representatives, relationships with agents or persons with whom the insurer does business, and other matters. Often these lawsuits have resulted in the award of substantial judgments that are disproportionate to the actual damages, including material amounts of punitive and non-economic compensatory damages. In some states, juries, judges, and arbitrators have substantial discretion in awarding punitive and non-economic compensatory damages which creates the potential for unpredictable material adverse judgments or awards in any given lawsuit or arbitration. Arbitration awards are subject to very limited appellate review. In addition, in some class action and other lawsuits, companies have made material settlement payments. The financial services and insurance industries in particular are also sometimes the target of law enforcement and regulatory investigations relating to the numerous laws and regulations that govern such companies. Some companies have been the subject of law enforcement or regulatory actions or other actions resulting from such investigations. The Company, in the ordinary course of business, is involved in such matters. The Company establishes liabilities for litigation and regulatory actions when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. For matters where a loss is believed to be reasonably possible, but not probable, no liability is established. For such matters, the Company may provide an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made. The Company reviews relevant information with respect to litigation and regulatory matters on a quarterly and annual basis and updates its established liabilities, disclosures and estimates of reasonably possible losses or range of loss based on such reviews. The Company and certain of its insurance subsidiaries, as well as certain other insurance companies for which the Company has coinsured blocks of life insurance and annuity policies, are under audit for compliance with the unclaimed property laws of a number of states. The audits are being conducted on behalf of the treasury departments or unclaimed property administrators in such states. The focus of the audits is on whether there have been unreported deaths, maturities, or policies that have exceeded limiting age with respect to which death benefits or other payments under life insurance or annuity policies should be treated as unclaimed property that should be escheated to the state. The Company is presently unable to estimate the reasonably possible loss or range of loss that may result from the audits due to a number of factors, including uncertainty as to the legal theory or theories that may give rise to liability, the early stages of the audits being conducted, and uncertainty as to whether the Company or other companies are responsible for the liabilities, if any, arising in connection with certain co-insured policies. The Company will continue to monitor the matter for any developments that would make the loss contingency associated with the audits reasonably estimable. The Company and certain of its subsidiaries are under a targeted multi-state examination with respect to their claims paying practices and their use of the U.S. Social Security Administration’s Death Master File or similar databases (a “Death Database”) to identify unreported deaths in their life insurance policies, annuity contracts and retained asset accounts. There is no clear basis in previously existing law for requiring a life insurer to search for unreported deaths in order to determine whether a benefit is owed, and substantial legal authority exists to support the position that the prevailing industry practice was lawful. A number of life insurers, however, have entered into settlement or consent agreements with state insurance regulators under which the life insurers agreed to implement procedures for periodically comparing their life insurance and annuity contracts and retained asset accounts against a Death Database, treating confirmed deaths as giving rise to a death benefit under their policies, locating beneficiaries and paying them the benefits and interest, escheating the benefits and interest to the state if the beneficiary could not be found, and paying penalties to the state, if required. It has been publicly reported that the life insurers have paid administrative and/or examination fees to the insurance regulators in connection with the settlement or consent agreements. The Company believes that insurance regulators could demand from the Company administrative and/or examination fees relating to the targeted multi-state examination. Based on publicly reported payments by other life insurers, the Company does not believe such fees, if assessed, would have a material effect on its financial statements.

Pension and Other Postretirement Benefits Cost (Reversal of Cost) [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Beginning with the December 31, 2015 measurement, PLC changed its method used to estimate the service and interest cost components of net periodic benefit cost for pension and other postretirement benefits by applying a spot rate approach. Historically, PLC utilized a single weighted average discount rate derived from a selected yield curve used to measure the benefit obligation as of the measurement date. Under the new spot rate approach, the actual calculation of service and interest cost will reflect an array of spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. PLC made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot rates from the selected yield curve. This new approach does not affect the measurement of the total benefit obligation. Qualified Pension Plan and Nonqualified Excess Pension Plan PLC sponsors the Qualified Pension Plan covering substantially all of its employees, including those of the Company. Benefits are based on years of service and the employee’s compensation. Effective January 1, 2008, PLC made the following changes to its Qualified Pension Plan. These changes have been reflected in the computations within this note. • Employees hired after December 31, 2007 and any former employee hired after that date, will receive a cash balance benefit. • Employees active on December 31, 2007, with age plus years of vesting service less than 55 years , will receive a final pay-based pension benefit for service through December 31, 2007, plus a cash balance benefit for service after December 31, 2007. • Employees active on December 31, 2007, with age plus years of vesting service equaling or exceeding 55 years , will receive a final pay-based pension benefit for service both before and after December 31, 2007, with a modest reduction in the formula for benefits earned after December 31, 2007. • All participants terminating employment on or after December of 2007 may elect to receive a lump sum benefit. In 2016, the Company amended its Qualified Pension Plan to offer a limited-time opportunity of benefit payouts to eligible, terminated-vested participants (“lump sum window”). The lump sum window provided eligible, terminated-vested participants with an option to elect to receive a lump sum settlement of his or her pension benefit in December 2016 or to elect receipt of monthly pension benefits commencing in December 2016. This event triggered settlement accounting for the Company and resulted in the recognition of $0.9 million of settlement income for the twelve months ended December 31, 2016 (Successor Company). The Company also sponsors the Nonqualified Excess Pension Plan, which is an unfunded nonqualified plan that provides defined pension benefits in excess of limits imposed on the Qualified Pension Plan by federal tax law. In 2016, the Board of Directors of Protective Life Corporation approved the conversion of the accrued benefit payable under the Nonqualified Excess Pension Plan as of March 31, 2016 to John D. Johns, the Company's Chairman and Chief Executive Officer at the time, into a lump sum amount. The lump sum amount is allocated to a book entry that will be treated as though it were a pay deferral account under the Company’s deferred compensation plan for officers. Mr. Johns will continue to accrue benefits as though he were accruing benefits under the Nonqualified Excess Pension Plan with respect to this continued service as an employee of the Company after March 31, 2016. The conversion event required the Company to re-measure the Nonqualified Excess Pension Plan as of May 31, 2016 and resulted in the recognition of $2.1 million in settlement expense during the twelve months ended December 31, 2016 (Successor Company). The following table presents the benefit obligation, fair value of plan assets, funded status, and amounts not yet recognized as components of net periodic pension costs for the Company's defined benefit pension plan and unfunded excess benefit plan as of December 31, 2017 and 2016 (Successor Company): Successor Company December 31, 2017 December 31, 2016 Qualified Pension Plan Nonqualified Excess Pension Plan Qualified Pension Plan Nonqualified Excess Pension PLan (Dollars In Thousands) Accumulated benefit obligation, end of year $ 278,084 $ 50,149 $ 247,595 $ 45,594 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 265,848 $ 47,802 $ 268,221 $ 56,985 Service cost 12,011 1,350 12,791 1,413 Interest cost 9,846 1,480 9,751 1,353 Amendments — — — — Actuarial loss/(gain) 26,539 7,861 5,988 4,124 Benefits paid (13,821 ) (3,903 ) (30,903 ) (16,073 ) Projected benefit obligation at end of year 300,423 54,590 265,848 47,802 Change in plan assets: Fair value of plan assets at beginning of year 201,843 — 196,042 — Actual return on plan assets 29,404 — 15,815 — Employer contributions (1) 43,500 3,903 20,889 16,073 Benefits paid (2) (13,821 ) (3,903 ) (30,903 ) (16,073 ) Fair value of plan assets at end of year 260,926 — 201,843 — After reflecting FASB guidance: Funded status (39,497 ) (54,590 ) (64,005 ) (47,802 ) Amounts recognized in the balance sheet: Other liabilities (39,497 ) (54,590 ) (64,005 ) (47,802 ) Amounts recognized in accumulated other comprehensive income: Net actuarial loss/(gain) 2,850 13,521 (7,855 ) 6,294 Prior service cost/(credit) — — — — Total amounts recognized in AOCI $ 2,850 $ 13,521 $ (7,855 ) $ 6,294 (1) Employer contributions disclosed are based on the Company's fiscal filing year (2) Includes amount related to Mr. Johns' conversion of his benefit under the Nonqualified Excess Pension Plan to a Retirement Pay Deferral Account as discussed above in Nonqualified Excess Pension Plan. Weighted-average assumptions used to determine benefit obligations as of December 31 are as follows: Successor Company Qualified Pension Plan Nonqualified Excess 2017 2016 2017 2016 Discount rate 3.55 % 4.04 % 3.26 % 3.60 % Rate of compensation increase 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above Weighted-average assumptions used to determine the net periodic benefit cost for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), and for the period of February 1, 2015 to December 31, 2015 (Successor Company), are as follows: Successor Company For The Year Ended December 31, 2017 2016 2015 2017 2016 2015 Qualified Pension Plan Nonqualified Excess Pension Plan Discount rate 4.04 % 4.29 % 3.95 % 3.60 % 3.63 % 3.63 % Rate of compensation increase 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above 4.75% prior to age 40/ 3.75% for age 40 and above Expected long-term return on plan assets 7.00 % 7.25 % 7.50 % N/A N/A N/A The assumed discount rates used to determine the benefit obligations were based on an analysis of future benefits expected to be paid under the plans. The assumed discount rate reflects the interest rate at which an amount that is invested in a portfolio of high-quality debt instruments on the measurement date would provide the future cash flows necessary to pay benefits when they come due. To determine an appropriate long-term rate of return assumption, PLC obtained a 25 year annualized return for each of the represented asset classes. In addition, PLC received evaluations of market performance based on PLC’s asset allocation as provided by external consultants. A combination of these statistical analytics provided results that PLC utilized to determine an appropriate long-term rate of return assumption. Components of the net periodic benefit cost for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company) are as follows: Successor Company Predecessor Company For The Year Ended For The Year Ended December 31, 2016 February 1, 2015 January 1, 2015 Qualified Pension Plan Nonqualified Excess Pension Plan Qualified Nonqualified Qualified Nonqualified Qualified Nonqualified (Dollars In Thousands) (Dollars In Thousands) Service cost — benefits earned during the period $ 12,011 $ 1,350 $ 12,791 $ 1,413 $ 11,220 $ 1,229 $ 974 $ 95 Interest cost on projected benefit obligation 9,846 1,480 9,751 1,353 9,072 1,499 1,002 140 Expected return on plan assets (13,570 ) — (13,780 ) — (13,214 ) — (1,293 ) — Amortization of prior service cost/(credit) — — — — — — (33 ) 1 Amortization of actuarial loss/(gain) (1) — 634 — 178 — — 668 138 Preliminary net periodic benefit cost 8,287 3,464 8,762 2,944 7,078 2,728 1,318 374 Settlement/curtailment expense (2) — — (964 ) 2,135 — — — — Total net periodic benefit cost $ 8,287 $ 3,464 $ 7,798 $ 5,079 $ 7,078 $ 2,728 $ 1,318 $ 374 (1) 2017 average remaining service period used is 9.24 years and 8.23 years for the Qualified Pension Plan and Nonqualified Excess Pension Plan, respectively. (2) The Nonqualified Excess Pension Plan triggered settlement accounting for the year ended December 31, 2016 since the total lump sum payments exceeded the settlement threshold of service cost plus interest cost. For the Qualified Pension Plan, the Company does not expect to amortize any net actuarial loss/(gain) from other comprehensive income into net periodic benefit cost during 2018 since the net actuarial loss/(gain) subject to amortization is less than 10% of the greater of the smooth value of assets or the projected benefit obligation. For the unfunded excess benefit plan, the Company expects to amortize approximately $1.0 million of net actuarial loss from other comprehensive income into net periodic benefit cost during 2018. Estimated future benefit payments under the Qualified Pension Plan and Nonqualified Excess Pension Plan are as follows: Years Qualified Pension Plan Nonqualified Excess Pension Plan (Dollars In Thousands) 2018 $ 19,479 $ 3,542 2019 20,719 7,242 2020 21,062 6,087 2021 21,351 5,709 2022 23,537 6,267 2023 - 2027 116,400 23,324 Qualified Pension Plan Assets Allocation of plan assets of the Qualified Pension Plan by category as of December 31 are as follows: Successor Company Asset Category Target 2017 (1) 2016 Cash and cash equivalents 2 % 15 % 2 % Equity securities 60 55 61 Fixed income 38 30 37 Total 100 % 100 % 100 % (1) During 2017, the Company made a $43.5 million contribution to the defined benefit pension plan and allocated the contribution to cash and cash equivalents pending further analysis of its investment strategy. The plan's investment policy was amended to allow for an actual asset allocation outside of the current target allocation until the investment strategy analysis is complete. The Company anticipates completing this analysis during the first quarter of 2018. PLC’s target asset allocation is designed to provide an acceptable level of risk and balance between equity assets and fixed income assets. The weighting towards equity securities is designed to help provide for an increased level of asset growth potential and liquidity. Prior to the amendment for the $43.5 million contribution made in 2017, the defined benefit pension plan had a target asset allocation of 60% domestic equities, 38% fixed income, and 2% cash. PLC's investment policy includes various guidelines and procedures designed to ensure assets are invested in a manner necessary to meet expected future benefits earned by participants. The investment guidelines consider a broad range of economic conditions. Central to the policy are target allocation ranges (shown above) by major asset categories. The objectives of the target allocations are to maintain investment portfolios that diversify risk through prudent asset allocation parameters, achieve asset returns that meet or exceed the plans' actuarial assumptions, and achieve asset returns that are competitive with like institutions employing similar investment strategies. PLC is currently performing an asset and liability study of its defined benefit pension plan and the associated investment portfolio to ensure that the current investment policy is appropriate for the plan. We anticipate this analysis being complete in the first quarter of 2018. The Qualified Pension Plan's equity assets are in a Russell 3000 index fund that invests in a domestic equity index collective trust managed by Northern Trust Corporation and in a Spartan 500 index fund managed by Fidelity. The Plan's cash is invested in a collective trust managed by Northern Trust Corporation. The plan's fixed income assets are invested in a group deposit administration annuity contract with PLICO. Plan assets of the Qualified Pension Plan by category as of December 31, 2017 and 2016 (Successor Company) are as follows: Successor Company As of December 31, Asset Category 2017 2016 (Dollars In Thousands) Cash and cash equivalents $ 39,897 $ 4,175 Equity securities: Collective Russell 3000 equity index fund 74,511 67,627 Fidelity Spartan 500 index fund 71,632 58,815 Fixed income 74,886 71,226 Total investments 260,926 201,843 Employer contribution receivable — — Total $ 260,926 $ 201,843 The valuation methodologies used to determine the fair values reflect market participant assumptions and are based on the application of the fair value hierarchy that prioritizes observable market inputs over unobservable inputs. The following is a description of the valuation methodologies used for assets measured at fair value. The Qualified Pension Plan's group deposit administration annuity contract with the Company is recorded at contract value, which PLC believes approximates fair value. Contract value represents contributions made under the contract, plus interest at the contract rate, less funds used to purchase annuities (the plan has not purchased annuities on behalf of participants under this contract during the periods presented). Units in collective short-term and collective investment funds are valued at the unit value, which approximates fair value, as reported by the trustee of the collective short-term and collective investment funds on each valuation date. These methods of valuation may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while PLC believes its valuation method is appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine fair value could result in a different fair value measurement at the reporting date. The following table sets forth by level, within the fair value hierarchy, the Qualified Pension Plan’s assets at fair value as of December 31, 2017 (Successor Company): Level 1 Level 2 Level 3 Total (Dollars In Thousands) Collective short-term investment fund $ 39,897 $ — $ — $ 39,897 Collective investment funds: Equity index funds 71,632 74,511 — 146,143 Group deposit administration annuity contract — — 74,886 74,886 Total investments $ 111,529 $ 74,511 $ 74,886 $ 260,926 The following table sets forth by level, within the fair value hierarchy, the Qualified Pension Plan’s assets at fair value as of December 31, 2016 (Successor Company): Level 1 Level 2 Level 3 Total (Dollars In Thousands) Collective short-term investment fund $ 4,175 $ — $ — $ 4,175 Collective investment funds: Equity index funds 58,815 67,627 — 126,442 Group deposit administration annuity contract — — 71,226 71,226 Total investments $ 62,990 $ 67,627 $ 71,226 $ 201,843 For the year ended December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), there were no transfers between levels. The following table summarizes the Qualified Pension Plan investments measured at fair value based on NAV per share as of December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), respectively: Name Fair Value Unfunded Commitments Redemption Frequency Redemption Notice Period (Dollars In Thousands) Successor Company As of December 31, 2017 Collective short-term investment fund $ 39,897 Not Applicable Daily 1 day Collective Russell 3000 index fund (1) 74,511 Not Applicable Daily 1 day Fidelity Spartan 500 index fund 71,632 Not Applicable Daily 1 day As of December 31, 2016 Collective short-term investment fund $ 4,175 Not Applicable Daily 1 day Collective Russell 3000 index fund (1) 67,627 Not Applicable Daily 1 day Fidelity Spartan 500 index fund 58,815 Not Applicable Daily 1 day (1) Non-lending collective trust that does not publish a daily NAV but tracks the Russell 3000 index and provides a daily NAV to the Plan. The following table presents a reconciliation of the beginning and ending balances for the fair value measurements for the year ended December 31, 2017 (Successor Company) and for the year ended December 31, 2016 (Successor Company) for which PLC has used significant unobservable inputs (Level 3): Successor Company December 31, 2017 December 31, 2016 (Dollars In Thousands) Balance, beginning of year $ 71,226 $ 67,707 Interest income 3,660 3,519 Transfers from collective short-term investments fund — — Transfers to collective short-term investments fund — — Balance, end of year $ 74,886 $ 71,226 The following table represents the Plan’s Level 3 financial instrument, the valuation technique used, and the significant unobservable input and the ranges of values for that input as of December 31, 2017 (Successor Company): Instrument Fair Value Principal Valuation Technique Significant Unobservable Inputs Range of Significant Input Values (Dollars In Thousands) Group deposit administration annuity contract $ 74,886 Contract Value Contract Rate 5.10% - 5.19% Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect the amounts reported. Qualified Pension Plan Funding Policy PLC's funding policy is to contribute amounts to the Qualified Pension Plan sufficient to meet the minimum funding requirements of the Employee Retirement Income Security Act ("ERISA") plus such additional amounts as PLC may determine to be appropriate from time to time. Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. Under the Pension Protection Act of 2006 ("PPA"), a plan could be subject to certain benefit restrictions if the plan's adjusted funding target attainment percentage ("AFTAP") drops below 80% . Therefore, PLC may make additional contributions in future periods to maintain an AFTAP of at least 80% . In general, the AFTAP is a measure of how well a plan is funded and is obtained by dividing a plan's assets by its funding liabilities. AFTAP is based on participant data, plan provisions, plan methods and assumptions, funding credit balances, and plan assets as of the plan valuation date. Some of the assumptions and methods used to determine a plan's AFTAP may be different from the assumptions and methods used to measure a plan's funded status on a GAAP basis. In July of 2012, the Moving Ahead for Progress in the 21st Century Act ("MAP-21"), which includes pension funding stabilization provisions, was signed into law. These provisions establish an interest rate corridor which is designed to stabilize the segment rates used to determine funding requirements from the effects of interest rate volatility. In August of 2014, the Highway and Transportation Funding Act of 2014 ("HATFA") was signed into law. HAFTA extends the funding relief provided by MAP-21 by delaying the interest rate corridor expansion. The funding stabilization provisions of MAP-21 and HATFA reduced the Company's minimum required Qualified Pension Plan contributions for the 2013 and 2014 plan years. Since the funding stabilization provisions of MAP-21 and HATFA do not apply for Pension Benefit Guaranty Corporation ("PBGC") reporting purposes, PLC may also make additional contributions in future periods to avoid certain PBGC reporting triggers. During the twelve months ended December 31, 2017, PLC contributed $43.5 million to the Qualified Pension Plan for the 2016 plan year. PLC has not yet determined what amount it will fund during 2018, but may contribute an amount that would eliminate the PGBC variable-rate premiums payable in 2018. PLC currently estimates that amount will be between $10 million and $20 million . Other Postretirement Benefits In addition to pension benefits, PLC provides limited healthcare benefits to eligible retired employees until age 65 . This postretirement benefit is provided by an unfunded plan. As of December 31, 2017 and 2016 (Successor Company), the accumulated postretirement benefit obligation and projected benefit obligation were immaterial. For a closed group of retirees over age 65, the Company provides a prescription drug benefit. As of December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), PLC's liability related to this benefit was immaterial. PLC also offers life insurance benefits for retirees from $10,000 up to a maximum of $75,000 which are provided through the payment of premiums under a group life insurance policy. This plan is partially funded at a maximum of $50,000 face amount of insurance. The benefit obligation associated with these benefits is as follows: Successor Company Postretirement Life Insurance Plan As of December 31, 2017 As of December 31, 2016 (Dollars In Thousands) Change in Benefit Obligation Benefit obligation, beginning of year $ 9,634 $ 9,063 Service cost 122 102 Interest cost 354 338 Actuarial (gain)/loss 1,347 604 Benefits paid (479 ) (473 ) Benefit obligation, end of year $ 10,978 $ 9,634 For the postretirement life insurance plan, PLC’s discount rate assumption used to determine the benefit obligation and the net periodic benefit cost as of December 31, 2017 (Successor Company) is 3.74% and 4.35% , respectively. PLC’s expected long-term rate of return assumption used to determine the net periodic benefit cost as of December 31, 2017 (Successor Company) is 2.75% . To determine an appropriate long-term rate of return assumption, PLC utilized 25 year average and annualized return results on the Barclay’s short treasury index. Investments of PLC’s group life insurance plan are held by Wells Fargo Bank, N.A. Plan assets held by the Custodian are invested in a money market fund. The fair value of each major category of plan assets for PLC’s postretirement life insurance plan is as follows Successor Company As of December 31, 2017 2016 (Dollars In Thousands) Category of Investment Money market fund $ 5,104 $ 5,362 Investments are stated at fair value and are based on the application of the fair value hierarchy that prioritizes observable market inputs over unobservable inputs. The money market funds are valued based on historical cost, which represents fair value, at year end. This method of valuation may produce a fair value calculation that may not be reflective of future fair values. Furthermore, while PLC believes its valuation method is appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine fair value could result in a different fair value measurement at the reporting date. The following table sets forth by level, within the fair value hierarchy, the life insurance plan's assets at fair value as of December 31, 2017 (Successor Company): Level 1 Level 2 Level 3 Total (Dollars In Thousands) Money market fund $ 5,104 $ — $ — $ 5,104 The following table sets forth by level, within the fair value hierarchy, the life insurance plan's assets at fair value as of December 31, 2016 (Successor Company): Level 1 Level 2 Level 3 Total (Dollars In Thousands) Money market fund $ 5,362 $ — $ — $ 5,362 For the year ended December 31, 2017 and 2016 (Successor Company), there were no transfers between levels. Investments are exposed to various risks, such as interest rate and credit risks. Due to the level of risk associated with investments and the level of uncertainty related to credit risks, it is at least reasonably possible that changes in risk in the near term could materially affect the amounts reported. 401(k) Plan PLC sponsors a tax qualified 401(k) Plan ("401(k) Plan") which covers substantially all employees. Employee contributions are made on a before-tax basis as provided by Section 401(k) of the Internal Revenue Code or as after-tax “Roth” contributions. Employees may contribute up to 25% of their eligible annual compensation to the 401(k) Plan, limited to a maximum annual contribution amount as set periodically by the Internal Revenue Service ( $18,000 for 2017 ). The Plan also provides a “catch-up” contribution provision which permits eligible participants (age 50 or over at the end of the calendar year), to make additional contributions that exceed the regular annual contribution limits up to a limit periodically set by the Internal Revenue Service ( $6,000 for 2017 ). PLC matches the sum of all employee contributions dollar for dollar up to a maximum of 4% of an employee’s pay per year per person. All matching contributions vest immediately. For the year ended December 31, 2017 (Successor Company) and December 31, 2016 (Successor Company), the Company recorded an expense of $8.2 million and $7.5 million associated with 401(k) Plan matching contributions, respectively. PLC also has a supplemental matching contribution program, which is a nonqualified plan that provides supplemental matching contributions in excess of the limits imposed on qualified defined contribution plans by federal tax law. The expense recorded by PLC for this employee benefit was $1.1 million , $0.6 million , and $0.5 million , respectively, in 2017 , 2016 , and 2015 . Deferred Compensation Plan On February 1, 2015, PLC became a wholly owned subsidiary of Dai-ichi Life and PLC stock ceased to be publicly traded. Thus, any common stock equivalents within the plans converted into rights to receive the merger consideration of $70.00 per common stock equivalent. As of February 1, 2015, PLC has continued the deferred compensation plans for officers and others. Compensation deferred was credited to the participants in cash, mutual funds, or a combination thereof. As of December 31, 2017 (Successor Company), PLC's obligations related to its deferred compensation plans are reported in other liabilities.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s effective income tax rate related to continuing operations varied from the maximum federal income tax rate as follows: Successor Company Predecessor Company For The Year Ended For The Year Ended December 31, 2016 February 1, 2015 January 1, 2015 Statutory federal income tax rate applied to pre-tax income 35.0 % 35.0 % 35.0 % 35.0 % State income taxes 0.3 0.6 1.4 0.5 Investment income not subject to tax (4.7 ) (3.1 ) (6.8 ) (2.8 ) Uncertain tax positions 0.3 0.3 — 0.5 Federal Tax law changes (184.8 ) — — — Other (0.9 ) (0.3 ) (0.3 ) 0.7 (154.8 )% 32.5 % 29.3 % 33.9 % The annual provision for federal income tax in these financial statements differs from the annual amounts of income tax expense reported in the respective income tax returns. Certain significant revenues and expenses are appropriately reported in different years with respect to the financial statements and the tax returns. The components of the Company’s income tax are as follows: Successor Company Predecessor Company For The Year Ended For The Year Ended December 31, 2016 February 1, 2015 January 1, 2015 (Dollars In Thousands) (Dollars In Thousands) Current income tax expense: Federal $ 39,042 $ (41,244 ) $ 50,722 $ (48,469 ) State (2,477 ) 2,581 (4,000 ) 1,085 Total current $ 36,565 $ (38,663 ) $ 46,722 $ (47,384 ) Deferred income tax expense: Federal $ (757,748 ) $ 204,810 $ 18,880 $ 90,774 State 2,774 3,926 8,889 935 Total deferred $ (754,974 ) $ 208,736 $ 27,769 $ 91,709 The components of the Company’s net deferred income tax liability are as follows: Successor Company As of December 31, 2017 2016 (Dollars In Thousands) Deferred income tax assets: Loss and credit carryforwards $ 240,419 $ 510,886 Deferred compensation 64,677 101,626 Deferred policy acquisition costs 23,113 155,009 Premium on non-recourse funding obligations 1,666 4,482 Net unrealized loss on investments — 353,149 Valuation allowance (3,682 ) (5,039 ) 326,193 1,120,113 Deferred income tax liabilities: Premium receivables and policy liabilities 538,465 819,476 VOBA and other intangibles 433,371 720,878 Invested assets (other than unrealized gains (losses)) 701,070 1,340,688 Net unrealized gains on investments 6,175 — Other 19,101 30,032 1,698,182 2,911,074 Net deferred income tax liability $ (1,371,989 ) $ (1,790,961 ) The Company’s income tax returns, except for MONY which files separately, are included in PLC’s consolidated U.S. income tax return. The deferred tax assets reported above include certain deferred tax assets related to nonqualified deferred compensation and other employee benefit liabilities that were assumed by AXA and they were not acquired by the Company in connection with the acquisition of MONY. The future tax deductions stemming from these liabilities will be claimed by the Company on MONY's tax returns in its post-acquisition periods. These deferred tax assets have been estimated as of the MONY Acquisition date (and through the December 31, 2017 reporting date) based on all available information. However, it is possible that these estimates may be adjusted in future reporting periods based on actuarial changes to the projected future payments associated with these liabilities. Any such adjustments will be recognized by the Company as an adjustment to income tax expense during the period in which they are realized. On December 22, 2017, the President of the United States signed into law the Tax Reform Act. The legislation significantly changes U.S. tax law by, among other things, lowering the corporate income tax rate. The Tax Reform Act permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% and changes to tax law related to the deductibility of certain deferred tax assets under the Tax Reform Act, we revalued our ending net deferred tax liabilities at December 31, 2017, and recognized a provisional $857.5 million tax benefit in our consolidated statement of income for the year ended December 31, 2017. Also on December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company has recognized the provisional tax impacts based on reasonable estimates made by the Company as to the effects of tax reform on deferred assets as discussed below and included these amounts in its consolidated financial statements for the year ended December 31, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional regulatory guidance that may be issued, additional analysis, and resulting changes in interpretations and assumptions the Company has made. Any adjustments to these provisional amounts will be reported as a component of income tax expense (benefit) in the reporting period in which any such adjustments are determined. The Company will not extend the measurement period beyond December 22, 2018. As a result of the Tax Reform Act, compensation paid to our covered employees in excess of $1 million will not be deductible unless it qualifies for transition relief applicable to certain written binding arrangements that were in place as of November 2, 2017 and that have not been materially modified after such date. Because of ambiguities and uncertainties as to the application and interpretation of Section 162(m), including the uncertain application of transition relief to companies that had not been subject to Section 162(m) prior to the effectiveness of the Tax Reform Act, it is unclear whether or to what extent the deferred tax assets related to amounts paid or payable by the Company to covered employees after January 1, 2018 pursuant to written binding arrangements that were in place on November 2, 2017 will be subject to the $1 million dollar deduction limit of Section 162(m). In management’s judgment, the gross deferred income tax asset as of December 31, 2017 (Successor Company) will more likely than not be fully realized. The Company has recognized a valuation allowance of $5.0 million and $7.8 million as of December 31, 2017 and 2016 (Successor Company), respectively, related to state-based loss carryforwards that it has determined are more likely than not to expire unutilized. This resulting favorable change of $2.8 million , before federal income taxes, decreased state income tax expense in 2017 by the same amount. At December 31, 2017 (Successor Company), the Company has life net operating loss carryforwards for federal income tax purposes of $578.3 million which are available to offset both future life group taxable income and non-life group taxable income through 2031. Alternative minimum tax credits of $8.6 million are available to offset regulat tax beginning 2018, as a result of the Tax Reform Act, with any remaining credits being fully refundable beginning in 2021. Foreign tax credits of $7.2 million are available to offset both future life group income tax and non-life group income tax and will begin to expire in 2024. In addition, included in the deferred income tax assets above are approximately $12.2 million in state net operating loss carryforwards attributable to certain jurisdictions, which are available to offset future taxable income in the respective state jurisdictions, expiring between 2018 and 2036. As of December 31, 2017 and 2016 (Successor Company), some of the Company's fixed maturities were reported at an unrealized loss, although the net amount is an unrealized gain at December 31, 2017 (Successor Company). If the Company were to realize a tax-basis net capital loss for a year, then such loss could not be deducted against that year's other taxable income. However, such a loss could be carried back and forward against any prior year or future year tax-basis net capital gains. Therefore, the Company has relied upon a prudent and feasible tax-planning strategy regarding its fixed maturities that were reported at an unrealized loss. The Company has the ability and the intent to either hold such fixed maturities to maturity, thereby avoiding a realized loss, or to generate an offsetting realized gain from unrealized gain fixed maturities if such unrealized loss fixed maturities are sold at a loss prior to maturity. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Successor Company Predecessor Company As of As of December 31, 2016 February 1, 2015 January 1, 2015 (Dollars In Thousands) (Dollars In Thousands) Balance, beginning of period $ 9,856 $ 8,937 $ 105,850 $ 168,076 Additions for tax positions of the current year 1,857 2,122 2,213 (5,010 ) Additions for tax positions of prior years 70 1,318 1,812 1,149 Reductions of tax positions of prior years: Changes in judgment (430 ) (975 ) (644 ) (58,365 ) Settlements during the period — (1,546 ) (100,294 ) — Lapses of applicable statute of limitations — — — — Balance, end of period $ 11,353 $ 9,856 $ 8,937 $ 105,850 Included in the end of period balance above, as of December 31, 2017 (Successor Company), December 31, 2016 (Successor Company), the period of February 1, 2015 to December 31, 2015 (Successor Company), and the period of January 1, 2015 to January 31, 2015 (Predecessor Company), are approximately $0.7 million , $0.7 million , $1.4 million , and $94.9 million of unrecognized tax benefits, respectively, for which the ultimate deductibility is certain but for which there is uncertainty about the timing of such deductions. Other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective income tax rate but would accelerate to an earlier period the payment of cash to the taxing authority. The total amount of unrecognized tax benefits, if recognized, that would affect the effective income tax rate is approximately $10.7 million , $9.2 million , $7.5 million , and $11.0 million for the year ended December 31, 2017 (Successor Company), December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. Any accrued interest related to the unrecognized tax benefits and other accrued income taxes have been included in income tax expense. There were no amounts included in any period ending in 2017 , 2016 , or 2015 , as the parent company maintains responsibility for the interest on unrecognized tax benefits. The Company has no accrued interest associated with unrecognized tax benefits as of any balance sheet date ending in 2017 , 2016 , or 2015 . In June 2012, the IRS proposed favorable and unfavorable adjustments to the Company’s 2003 through 2007 reported taxable incomes. The Company protested certain unfavorable adjustments and sought resolution at the IRS’ Appeals Division. In October 2015, Appeals accepted the Company’s earlier proposed settlement offer. In September 2015, the IRS proposed favorable and unfavorable adjustments to the Company’s 2008 through 2011 reported taxable income. The Company agreed to these adjustments. In April 2017, a routine review by Congress' Joint Committee on Taxation was finalized without change and the Company received an approximate $6.2 million net refund in the fourth quarter of 2017. The resulting net adjustment to the Company’s current income taxes for the years 2003 through 2011 did not materially affect the Company or its effective tax rate. In July 2016, the IRS proposed favorable and unfavorable adjustments to the Company's 2012 and 2013 reported taxable income. The Company agreed to these adjustments. The resulting settlement paid in September 2016 did not materially impact the Company or its effective tax rate. These agreements with the IRS are the primary cause for the reductions of unrecognized tax benefits shown in the above chart. The Company believes that in the next 12 months, $0.7 million of the unrecognized tax benefits will be reduced due to recent changes in tax law. In general, the Company is no longer subject to income tax examinations by taxing authorities for tax years that began before 2014. Due to the aforementioned IRS adjustments to the Company's pre-2014 taxable income, the Company is amending certain of its 2003 through 2013 state income tax returns. Such amendments will cause such years to remain open, pending the states' acceptances of the returns. During the year ended December 31, 2016 (Successor Company), the Company filed a non-automatic tax accounting method change related to income recognition for unearned premium reserve and discounted loss reserve for claims incurred. The IRS accepted the Company's request for the non-automatic tax accounting method. This change did not materially impact the Company or its effective tax rate.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company provides furnished office space and computers to affiliates through an intercompany agreement. Revenues from this agreement were $6.2 million , $5.8 million , $4.6 million , and $0.4 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. The Company purchases data processing, legal, investment, and management services from affiliates. The costs of such services were $240.9 million , $258.0 million , $214.8 million , and $19.0 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. In addition, the Company has an intercompany payable with affiliates as of December 31, 2017 and 2016 of $68.3 million and $14.9 million , respectively. There was a $26.1 million intercompany receivable with affiliates balance as of December 31, 2017 (Successor Company). The Company did not have an intercompany receivable balance as of December 31, 2016 (Successor Company). Certain corporations with which PLC’s directors were affiliated paid us premiums and policy fees or other amounts for various types of insurance and investment products, interest on bonds we own and commissions on securities underwritings in which our affiliates participated. Such amounts totaled $6.8 million , $7.2 million , $45.3 million , and $2.6 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. The Company and/or PLC paid commissions, interest on debt and investment products, and fees to these same corporations totaling $6.5 million , $8.6 million , $10.0 million , and $0.8 million for the year ended December 31, 2017 (Successor Company), for the year ended December 31, 2016 (Successor Company), for the period of February 1, 2015 to December 31, 2015 (Successor Company), and for the period of January 1, 2015 to January 31, 2015 (Predecessor Company), respectively. Prior to the Merger, PLC and the Company had no related party transactions with Dai-ichi Life. During the period ending December 31, 2017 (Successor Company), PLC paid a management fee to Dai-ichi Life of $10.9 million for certain services provided to the company. PLC has guaranteed the Company’s obligations for borrowings or letters of credit under the revolving line of credit arrangement to which PLC is also a party. PLC has also issued guarantees, entered into support agreements and/or assumed a duty to indemnify its indirect wholly owned captive insurance companies in certain respects. As of February 1, 2000, PLC guaranteed the obligations of the Company under a synthetic lease entered into by the Company, as lessee, with a non-affiliated third party, as lessor. Under the terms of the synthetic lease, financing of $75 million was available to the Company for construction of an office building and parking deck which was completed on February 1, 2000. The synthetic lease was amended and restated as of December 19, 2013, wherein as of December 31, 2017 , PLC continued to guarantee the obligations of the Company thereunder. The Company has agreements with certain of its subsidiaries under which it provides administrative services for a fee. These services include but are not limited to accounting, financial reporting, compliance, policy administration, reserve computations, and projections. In addition, the Company and its subsidiaries pay PLC for investment, legal and data processing services. The Company and/or certain of its affiliates have reinsurance agreements in place with companies owned by PLC. These agreements relate to certain portions of our service contract business which is included within the Asset Protection segment. These transactions are eliminated at the PLC consolidated level. The Company has reinsured GLWB and GMDB riders related to our variable annuity contracts to Shades Creek, a wholly owned insurance subsidiary of PLC. Also during 2012, PLC entered into an intercompany capital support agreement with Shades Creek which provides through a guarantee that PLC will contribute assets or purchase surplus notes (or cause an affiliate or third party to contribute assets or purchase surplus notes) in amounts necessary for Shades Creek’s regulatory capital levels to equal or exceed minimum thresholds as defined by the agreement. No additional capital was provided to Shades Creek by PLC during the year ended December 31, 2017 (Successor Company). As of December 31, 2017 (Successor Company), Shades Creek maintained capital levels in excess of the required minimum thresholds. The maximum potential future payment amount which could be required under the capital support agreement will be dependent on numerous factors, including the performance of equity markets, the level of interest rates, performance of associated hedges, and related policyholder behavior.

STATUTORY REPORTING PRACTICES A

STATUTORY REPORTING PRACTICES AND OTHER REGULATORY MATTERS
STATUTORY REPORTING PRACTICES AND OTHER REGULATORY MATTERS	STATUTORY REPORTING PRACTICES AND OTHER REGULATORY MATTERS The Company and its insurance subsidiaries prepare statutory financial statements for regulatory purposes in accordance with accounting practices prescribed by the NAIC and the applicable state insurance department laws and regulations. These financial statements vary materially from GAAP. Statutory accounting practices include publications of the NAIC, state laws, regulations, general administrative rules as well as certain permitted accounting practices granted by the respective state insurance department. Generally, the most significant differences are that statutory financial statements do not reflect 1) deferred acquisition costs and VOBA, 2) benefit liabilities that are calculated using Company estimates of expected mortality, interest, and withdrawals, 3) deferred income taxes that are not subject to statutory limits, 4) recognition of realized gains and losses on the sale of securities in the period they are sold, and 5) fixed maturities recorded at fair values, but instead at amortized cost. Statu tory net income (loss) for the Company was $731.2 million , $(391.6) million , and $440.0 million for the year ended December 31, 2017 , 2016 , and 2015 , respectively. Statutory capital and surplus for the Company was $4.3 billion and $4.2 billion as of December 31, 2017 and 2016 , respectively. The Statutory net loss incurred by the Company for the year ended December 31, 2016 was caused by the required Statutory accounting treatment of the initial gain recognized on the retrocession of the term business assumed from Genworth Life and Annuity Insurance Company to Golden Gate Captive Insurance Company, which resulted in approximately a $1.2 billion gain being included as a component of surplus, rather than reflected in Statutory net income as of the January 15, 2016 cession date. The Company and its insurance subsidiaries are subject to various state statutory and regulatory restrictions on the insurance subsidiaries’ ability to pay dividends to Protective Life Corporation. In general, dividends up to specified levels are considered ordinary and may be paid thirty days after written notice to the insurance commissioner of the state of domicile unless such commissioner objects to the dividend prior to the expiration of such period. Dividends in larger amounts are considered extraordinary and are subject to affirmative prior approval by such commissioner. The maximum amount that would qualify as ordinary dividends to the Company from our insurance subsidiaries in 2018 is approximately $175.1 million . Additionally, as of December 31, 2017 , approximately $1.8 billion of consolidated shareowner’s equity, excluding net unrealized gains on investments, represented restricted net assets of the Company’s insurance subsidiaries needed to maintain the minimum capital required by the insurance subsidiaries’ respective state insurance departments. State insurance regulators and the National Association of Insurance Commissioners ("NAIC") have adopted risk-based capital ("RBC") requirements for life insurance companies to evaluate the adequacy of statutory capital and surplus in relation to investment and insurance risks. The requirements provide a means of measuring the minimum amount of statutory surplus appropriate for an insurance company to support its overall business operations based on its size and risk profile. A company’s risk-based statutory surplus is calculated by applying factors and performing calculations relating to various asset, premium, claim, expense and reserve items. Regulators can then measure the adequacy of a company’s statutory surplus by comparing it to the RBC. Under specific RBC requirements, regulatory compliance is determined by the ratio of a company’s total adjusted capital, a s defined by the insurance regulators, to its company action level of RBC (known as the RBC ratio), also as defined by insurance regulators. As of December 31, 2017 , the Company’s total adjusted capital and company action level RBC were approximately $4.7 billion and $759.3 million , respectively, providing an RBC ratio of approximately 614% . Additionally, the Company has certain assets that are on deposit with state regulatory authorities and restricted from use. As of December 31, 2017 , the Company and its insurance subsidiaries had on deposit with regulatory authorities, fixed maturity and short-term investments with a fair value of approximately $42.4 million . The states of domicile of the Company and its insurance subsidiaries have adopted prescribed accounting practices that differ from the required accounting outlined in NAIC Statutory Accounting Principles (“SAP”). The insurance subsidiaries also have certain accounting practices permitted by the states of domicile that differ from those found in NAIC SAP. Certain prescribed and permitted practices impact the statutory surplus of the Company. These practices include the non-admission of goodwill as an asset for statutory reporting and the reporting of Bank Owned Life Insurance (“BOLI”) separate account amounts at book value rather than at fair value. The favorable (unfavorable) effects of the Company and its statutory surplus, compared to NAIC statutory surplus, from the use of these prescribed and permitted practices were as follows: As of December 31, 2017 2016 (Dollars In Millions) Non-admission of goodwill $ (219 ) $ (257 ) Total (net) $ (219 ) $ (257 ) The Company also has certain prescribed and permitted practices which are applied at the subsidiary level and do not have a direct impact on the statutory surplus of the Company. These practices include permission to follow the actuarial guidelines of the domiciliary state of the ceding insurer for certain captive reinsurers, accounting for the face amount of all issued and outstanding letters of credit, and a note issued by an affiliate as an asset in the statutory financial statements of certain wholly owned subsidiaries that are considered “Special Purpose Financial Captives,” and a reserve difference related to a captive insurance company. The favorable (unfavorable) effects on the statutory surplus of the Company’s insurance subsidiaries, compared to NAIC statutory surplus, from the use of these prescribed and permitted practices were as follows: As of December 31, 2017 2016 (Dollars In Millions) Accounting for Letters of Credit as admitted assets $ 1,670 $ 1,720 Accounting for certain notes as admitted assets $ 2,634 $ 2,681 Reserving based on state specific actuarial practices $ 122 $ 120 Reserving difference related to a captive insurance company $ (37 ) $ (109 )

OPERATING SEGMENTS

Segment Reporting [Abstract]
OPERATING SEGMENTS	OPERATING SEGMENTS The Company has several operating segments, each having a strategic focus. An operating segment is distinguished by products, channels of distribution, and/or other strategic distinctions. The Company periodically evaluates its operating segments and makes adjustments to its segment reporting as needed. A brief description of each segment follows. • The Life Marketing segment markets fixed UL, IUL, VUL, BOLI, and level premium term insurance (“traditional”) products on a national basis primarily through networks of independent insurance agents and brokers, broker-dealers, financial institutions, independent distribution organizations, and affinity groups. • The Acquisitions segment focuses on acquiring, converting, and servicing policies and contracts acquired from other companies. The segment’s primary focus is on life insurance policies and annuity products that were sold to individuals. The level of the segment’s acquisition activity is predicated upon many factors, including available capital, operating capacity, potential return on capital, and market dynamics. Policies acquired through the Acquisitions segment are typically blocks of business where no new policies are being marketed. Therefore earnings and account values are expected to decline as the result of lapses, deaths, and other terminations of coverage unless new acquisitions are made. • The Annuities segment markets fixed and VA products. These products are primarily sold through broker-dealers, financial institutions, and independent agents and brokers. • The Stable Value Products segment sells fixed and floating rate funding agreements directly to the trustees of municipal bond proceeds, money market funds, bank trust departments, and other institutional investors. This segment also issues funding agreements to the FHLB, and markets GICs to 401(k) and other qualified retirement savings plans. The Company also has an unregistered funding agreement-backed notes program which provides for offers of notes to both domestic and international institutional investors. • The Asset Protection segment markets extended service contracts, GAP products, credit life and disability insurance, and other specialized ancillary products to protect consumers’ investments in automobiles and recreational vehicles. GAP covers the difference between the loan pay-off amount and an asset’s actual cash value in the case of a total loss. Each type of specialized ancillary product protects against damage or other loss to a particular aspect of the underlying asset. • The Corporate and Other segment primarily consists of net investment income on assets supporting our equity capital, unallocated corporate overhead and expenses not attributable to the segments above. This segment includes earnings from several non-strategic or runoff lines of business, various financing and investment related transactions, and the operations of several small subsidiaries. The Company's management and Board of Directors analyzes and assesses the operating performance of each segment using "pre-tax adjusted operating income (loss)" and "after-tax adjusted operating income (loss)". Consistent with GAAP accounting guidance for segment reporting, pre-tax adjusted operating income (loss) is the Company's measure of segment performance. Pre-tax adjusted operating income (loss) is calculated by adjusting "income (loss) before income tax", by excluding the following items: • realized gains and losses on investments and derivatives, • changes in the GLWB embedded derivatives exclusive of the portion attributable to the economic cost of the GLWB, • actual GLWB incurred claims, and • the amortization of DAC, VOBA, and certain policy liabilities that is impacted by the exclusion of these items. The items excluded from adjusted operating income (loss) are important to understanding the overall results of operations. Pre-tax adjusted operating income (loss) and after-tax adjusted operating income (loss) are not substitutes for income before income taxes or net income (loss), respectively. These measures may not be comparable to similarly titled measures reported by other companies. The Company believes that pre-tax and after-tax adjusted operating income (loss) enhances management's and the Board of Directors' understanding of the ongoing operations, the underlying profitability of each segment, and helps facilitate the allocation of resources. After-tax adjusted operating income (loss) is derived from pre-tax adjusted operating income (loss) with the inclusion of income tax expense or benefits associated with pre-tax adjusted operating income. Income tax expense or benefits is allocated to the items excluded from pre-tax adjusted operating income (loss) at the statutory federal income tax rate for the associated period. For periods ending on and prior to December 31, 2017, a rate of 35% was used. Beginning in 2018, a statutory federal income tax rate of 21% will be used to allocate income tax expense or benefits to items excluded from pre-tax adjusted operating income (loss). Income tax expense or benefits allocated to after-tax adjusted operating income (loss) can vary period to period based on changes in the Company's effective income tax rate. In determining the components of the pre-tax adjusted operating income (loss) for each segment, premiums and policy fees, other income, benefits and settlement expenses, and amortization of DAC and VOBA are attributed directly to each operating segment. Net investment income is allocated based on directly related assets required for transacting the business of that segment. Realized investment gains (losses) and other operating expenses are allocated to the segments in a manner that most appropriately reflects the operations of that segment. Investments and other assets are allocated based on statutory policy liabilities net of associated statutory policy assets, while DAC/VOBA and goodwill are shown in the segments to which they are attributable. During 2016, the Company modified its labeling of its non-GAAP measures presented herein as "Adjusted operating income (loss)" or "Pre-tax adjusted operating income (loss)". In previous filings, the Company referred to "Pre-tax adjusted operating income (loss)" as "Pre-tax operating income, "Operating income before tax", or "Segment operating income". In addition, the Company referred to "After-tax adjusted operating income (loss)" as "After-tax operating income" or "Operating earnings". The definition of these labels remains unchanged, but the Company has modified the labels to provide further clarity that these measures are non-GAAP. There were no significant intersegment transactions during the year ended December 31, 2017 (Successor Company), the year ended December 31, 2016 (Successor Company), the period of February 1, 2015 to December 31, 2015 (Successor Company), and the period of January 1, 2015 to January 31, 2015 (Predecessor Company).

In the opinion of management, all adjustments (consisting only of normal recurring items) necessary for a fair statement of quarterly results have been reflected in the following data. It is also management's opinion, however, that quarterly operating data for insurance enterprises are not necessarily indicative of results that may be expected in succeeding quarters or years. In order to obtain a more accurate indication of performance, there should be a review of operating results, changes in shareowner's equity, and cash flows for a period of several quarters.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs ("DAC") and related amortization periods, goodwill recoverability, value of business acquired ("VOBA"), investment and certain derivatives fair values, other-than-temporary impairments, future policy benefits, pension and other postretirement benefits, provisions for income taxes, reserves for contingent liabilities, reinsurance risk transfer assessments, and reserves for losses in connection with unresolved legal matters.
Valuation of Investment Securities	Valuation of Investment Securities The Company determines the appropriate classification of investment securities at the time of purchase and periodically re-evaluates such designations. Investment securities are classified as either trading, available-for-sale, or held-to-maturity securities. Investment securities classified as trading are recorded at fair value with changes in fair value recorded in realized gains (losses). Investment securities purchased for long term investment purposes are classified as available-for-sale and are recorded at fair value with changes in unrealized gains and losses, net of taxes, reported as a component of other comprehensive income (loss). Investment securities are classified as held-to-maturity when the Company has the intent and ability to hold the securities to maturity and are reported at amortized cost. Interest income on available-for-sale and held-to-maturity securities includes the amortization of premiums and accretion of discounts and are recorded in investment income. The fair value of fixed maturity, short-term, and equity securities is determined by management after considering one of three primary sources of information: third party pricing services, non-binding independent broker quotations, or pricing matrices. Security pricing is applied using a "waterfall" approach whereby publicly available prices are first sought from third party pricing services, the remaining unpriced securities are submitted to independent brokers for non-binding prices, or lastly, securities are priced using a pricing matrix. Typical inputs used by these three pricing methods include, but are not limited to: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. Based on the typical trading volumes and the lack of quoted market prices for available-for-sale and trading fixed maturities, third party pricing services derive the majority of security prices from observable market inputs such as recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information as outlined above. If there are no recent reported trades, the third party pricing services and brokers may use matrix or model processes to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Certain securities are priced via independent non-binding broker quotations, which are considered to have no significant unobservable inputs. When using non-binding independent broker quotations, the Company obtains one quote per security, typically from the broker from which the Company purchased the security. A pricing matrix is used to price securities for which the Company is unable to obtain or effectively rely on either a price from a third party service or an independent broker quotation. Included in the pricing of other asset-backed securities, collateralized mortgage obligations ("CMOs"), and mortgage-backed securities ("MBS") are estimates of the rate of future prepayments of principal and underlying collateral support over the remaining life of the securities. Such estimates are derived based on the characteristics of the underlying structure and rates of prepayments previously experienced at the interest rate levels projected for the underlying collateral. The basis for the cost of securities sold was determined at the Committee on Uniform Securities Identification Procedures ("CUSIP") level on a first in first out basis. The committee supplies a unique nine-character identification, called a CUSIP number, for each class of security approved for trading in the U.S., to facilitate clearing and settlement. These numbers are used when any buy and sell orders are recorded. Each quarter the Company reviews investments with unrealized losses and tests for other-than-temporary impairments. The Company analyzes various factors to determine if any specific other-than-temporary asset impairments exist. These include, but are not limited to: 1) actions taken by rating agencies, 2) default by the issuer, 3) the significance of the decline, 4) an assessment of the Company's intent to sell the security (including a more likely than not assessment of whether the Company will be required to sell the security) before recovering the security's amortized cost, 5) the duration of the decline, 6) an economic analysis of the issuer's industry, and 7) the financial strength, liquidity, and recoverability of the issuer. Management performs a security by security review each quarter in evaluating the need for any other-than-temporary impairments. Although no set formula is used in this process, the investment performance, collateral position, and continued viability of the issuer are significant measures considered, and in some cases, an analysis regarding the Company's expectations for recovery of the security's entire amortized cost basis through the receipt of future cash flows is performed. Once a determination has been made that a specific other-than-temporary impairment exists, the security's basis is adjusted and an other-than-temporary impairment is recognized. Equity securities that are other-than-temporarily impaired are written down to fair value with a realized loss recognized in earnings. Other-than-temporary impairments to debt securities that the Company does not intend to sell and does not expect to be required to sell before recovering the security's amortized cost are written down to discounted expected future cash flows ("post impairment cost") and credit losses are recorded in earnings. The difference between the securities' discounted expected future cash flows and the fair value of the securities on the impairment date is recognized in other comprehensive income (loss) as a non-credit portion impairment. When calculating the post impairment cost for residential mortgage-backed securities ("RMBS"), commercial mortgage-backed securities ("CMBS"), and other asset-backed securities (collectively referred to as asset-backed securities or "ABS"), the Company considers all known market data related to cash flows to estimate future cash flows. When calculating the post impairment cost for corporate debt securities, the Company considers all contractual cash flows to estimate expected future cash flows. To calculate the post impairment cost, the expected future cash flows are discounted at the original purchase yield. Debt securities that the Company intends to sell or expects to be required to sell before recovery are written down to fair value with the change recognized in earnings.
Cash	Cash Cash includes all demand deposits reduced by the amount of outstanding checks and drafts. As a result of the Company’s cash management system, checks issued from a particular bank but not yet presented for payment may create negative book cash balances with the bank at certain reporting dates. Such negative balances are included in other liabilities and were $132.7 million as of December 31, 2017 (Successor Company) and $79.2 million as of December 31, 2016 (Successor Company), respectively. The Company has deposits with certain financial institutions which exceed federally insured limits. The Company has reviewed the creditworthiness of these financial institutions and believes there is minimal risk of a material loss.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs The incremental direct costs associated with successfully acquired insurance policies, are deferred to the extent such costs are deemed recoverable from future profits. Such costs include commissions and other costs of acquiring traditional life and health insurance, credit insurance, universal life insurance, and investment products. DAC are subject to recoverability testing at the end of each accounting period. Traditional life and health insurance acquisition costs are amortized over the premium-payment period of the related policies in proportion to the ratio of annual premium income to the present value of the total anticipated premium income. Credit insurance acquisition costs are being amortized in proportion to earned premium. Acquisition costs for universal life and investment products are amortized over the lives of the policies in relation to the present value of estimated gross profits before amortization. The Company makes certain assumptions regarding the mortality, persistency, expenses, and interest rates (equal to the rate used to compute liabilities for future policy benefits, currently 1.0% to 7.8% ) the Company expects to experience in future periods when determining the present value of estimated gross profits. These assumptions are best estimates and are periodically updated whenever actual experience and/or expectations for the future change from that assumed. Additionally, these costs have been adjusted by an amount equal to the amortization that would have been recorded if unrealized gains or losses on investments associated with our universal life and investment products had been realized. Acquisition costs for stable value contracts are amortized over the term of the contracts using the effective yield method.
Value of Businesses Acquired	Value of Businesses Acquired In conjunction with the Merger and the acquisition of insurance policies or investment contracts, a portion of the purchase price is allocated to the right to receive future gross profits from cash flows and earnings of associated insurance policies and investment contracts. This intangible asset, called VOBA, is based on the actuarially estimated present value of future cash flows from associated insurance policies and investment contracts acquired. The estimated present value of future cash flows used in the calculation of the VOBA is based on certain assumptions, including mortality, persistency, expenses, and interest rates that the Company expects to experience in future years. The Company amortizes VOBA in proportion to gross premiums for traditional life products, or estimated gross margins ("EGMs") for participating traditional life products within the MONY Life Insurance Company ("MONY") block. For interest sensitive products, the Company uses various amortization bases including expected gross profits ("EGPs"), revenues, or insurance in-force. VOBA is subject to annual recoverability testing.
Intangible Assets	Intangible Assets Intangible assets with definite lives are amortized over the estimated useful life of the asset and reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Amortizable intangible assets primarily consist of distribution relationships, trade names, technology, and software. Intangible assets with indefinite lives, primarily insurance licenses, are not amortized, but are reviewed for impairment on an annual basis or whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Software is generally amortized over a three year useful life.
Property and Equipment	Property and Equipment In conjunction with the Merger, property and equipment was recorded at fair value as of the Merger date and will be depreciated from this basis in future periods based on the respective estimated useful lives. Real estate assets were recorded at appraised values as of the acquisition date. The Company has estimated the remaining useful life of the home office building to be 25 years . Land is not depreciated. The Company depreciates its assets using the straight-line method over the estimated useful lives of the assets. The Company’s furniture is depreciated over a ten year useful life, office equipment and machines are depreciated over a five year useful life, and computers are depreciated over a three year useful life. Major repairs or improvements ar e capitalized and depreciated over the estimated useful lives of the assets. Other repairs are expensed as incurred. The cost and related accumulated depreciation of property and equipment sold or retired are removed from the accounts, and resulting gains or losses are included in income.
Separate Accounts	Separate Accounts The separate account assets represent funds for which the Company does not bear the investment risk. These assets are carried at fair value and are equal to the separate account liabilities, which represent the policyholder's equity in those assets. The investment income and investment gains and losses on the separate account assets accrue directly to the policyholder. These amounts are reported separately as assets and liabilities related to separate accounts in the accompanying consolidated financial statements. Amounts assessed against policy account balances for the costs of insurance, policy administration, and other services are included in premiums and policy fees in the accompanying consolidated statements of income.
Stable Value Product Account Balances	Stable Value Product Account Balances The Stable Value Products segment sells fixed and floating rate funding agreements directly to qualified institutional investors. The segment also issues funding agreements to the Federal Home Loan Bank ("FHLB"), and markets guaranteed investment contracts ("GICs") to 401(k) and other qualified retirement savings plans. GICs are contracts which specify a return on deposits for a specified period and often provide flexibility for withdrawals at book value in keeping with the benefits provided by the plan. The Company records its stable value contract liabilities in the consolidated balance sheets in “stable value product account balances” at the deposit amount plus accrued interest, adjusted for any unamortized premium or discount. Interest on the contracts is accrued based upon contract terms. Any premium or discount is amortized using the effective yield method. The segment’s products complement the Company’s overall asset/liability management in that the terms may be tailored to the needs of the Company as the seller of the contracts. Stable value product account balances include GICs and funding agreements the Company has issued.
Derivative Financial Instruments	Derivative Financial Instruments The Company records its derivative financial instruments in the consolidated balance sheet in "other long-term investments" and "other liabilities" in accordance with GAAP, which requires that all derivative instruments be recognized in the balance sheet at fair value. The change in the fair value of derivative financial instruments is reported either in the statement of income or in the statement of other comprehensive income (loss), depending upon whether the derivative instrument qualified for and also has been properly identified as being part of a hedging relationship, and also on the type of hedging relationship that exists. For cash flow hedges, the effective portion of their gain or loss is reported as a component of other comprehensive income (loss) and reclassified into earnings in the period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. Effectiveness of the Company's hedge relationships is assessed on a quarterly basis. The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship in earnings. Changes in the fair value of derivatives that are recognized in current earnings are reported in "Realized investment gains (losses)—Derivative financial instruments".
Insurance Liabilities and Reserves	Insurance Liabilities and Reserves Establishing an adequate liability for the Company's obligations to policyholders requires the use of certain assumptions. Estimating liabilities for future policy benefits on life and health insurance products requires the use of assumptions relative to future investment yields, mortality, morbidity, persistency, and other assumptions based on the Company's historical experience, modified as necessary to reflect anticipated trends and to include provisions for possible adverse deviation. Determining liabilities for the Company's property and casualty insurance products also requires the use of assumptions, including the projected levels of used vehicle prices, the frequency and severity of claims, and the effectiveness of internal processes designed to reduce the level of claims. The Company's results depend significantly upon the extent to which its actual claims experience is consistent with the assumptions the Company used in determining its reserves and pricing its products. The Company's reserve assumptions and estimates require significant judgment and, therefore, are inherently uncertain. The Company cannot determine with precision the ultimate amounts that it will pay for actual claims or the timing of those payments.
Guaranteed Living Withdrawal Benefits	Guaranteed Living Withdrawal Benefits The Company also establishes reserves for guaranteed living withdrawal benefits (“GLWB”) on its variable annuity (“VA”) products. The GLWB is valued in accordance with FASB guidance under the ASC Derivatives and Hedging Topic which utilizes the valuation technique prescribed by the ASC Fair Value Measurements and Disclosures Topic, which requires the embedded derivative to be recorded at fair value using current implied volatilities for the equity indices. The fair value of the GLWB is impacted by equity market conditions and can result in the GLWB embedded derivative being in an overall net asset or net liability position. In times of favorable equity market conditions the likelihood and severity of claims is reduced and expected fee income increases. Since claims are generally expected later than fees, these favorable equity market conditions can result in the present value of fees being greater than the present value of claims, which results in a net GLWB embedded derivative asset. In times of unfavorable equity market conditions the likelihood and severity of claims is increased and expected fee income decreases and can result in the present value of claims exceeding the present value of fees resulting in a net GLWB embedded derivative liability. The methods used to estimate the embedded derivatives employ assumptions about mortality, lapses, policyholder behavior, equity market returns, interest rates, and market volatility. The Company assumes age-based mortality from the Ruark 2015 ALB adjusted table for company experience. Differences between the actual experience and the assumptions used result in variances in profit and could result in losses. The Company reinsures certain risks associated with the GLWB to Shades Creek Captive Insurance (“Shades Creek”), a direct wholly owned insurance subsidiary of PLC.
Goodwill	Goodwill The balance recognized as goodwill is not amortized, but is reviewed for impairment on an annual basis, or more frequently as events or circumstances may warrant, including those circumstances which would more likely than not reduce the fair value of the Company’s reporting units below its carrying amount. Accounting for goodwill requires an estimate of the future profitability of the associated lines of business within the Company's operating segments to assess the recoverability of the capitalized acquisition goodwill. The Company’s material goodwill balances are attributable to certain of its operating segments (which are each considered to be reporting units). The Company evaluates the carrying value of goodwill at the segment (or reporting unit) level at least annually and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Such circumstances could include, but are not limited to: 1) a significant adverse change in legal factors or in business climate, 2) unanticipated competition, or 3) an adverse action or assessment by a regulator. When evaluating whether goodwill is impaired, the Company first determines through qualitative analysis whether relevant events and circumstances indicate that it is more likely than not that segment goodwill balances are impaired as of the testing date. If the qualitative analysis does not indicate that an impairment of segment goodwill is more likely than not then no other specific quantitative impairment testing is required. If it is determined that it is more likely than not that impairment exists, the Company performs a quantitative assessment and compares its estimate of the fair value of the reporting unit to which the goodwill is assigned to the reporting unit’s carrying amount, including goodwill. The Company utilizes a fair value measurement (which includes a discounted cash flows analysis) to assess the carrying value of the reporting units in consideration of the recoverability of the goodwill balance assigned to each reporting unit as of the measurement date. The cash flows used to determine the fair value of the Company’s reporting units are dependent on a number of significant assumptions. The Company’s estimates, which consider a market participant view of fair value, are subject to change given the inherent uncertainty in predicting future results and cash flows, which are impacted by such things as policyholder behavior, competitor pricing, capital limitations, new product introductions, and specific industry and market conditions.
Income Taxes	Income Taxes The Company 's income tax returns, except for MONY which files separately, are included in PLC's consolidated U.S. income tax return. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the "Tax Reform Act"). Further information on the tax impacts of the Tax Reform Act is included in Note 19, Income Taxes . The Company uses the asset and liability method of accounting for income taxes. Generally, most items in pretax book income are also included in taxable income in the same year. However, some items are recognized for book purposes and for tax purposes in different years or are never recognized for either book or tax purposes. Those differences that will never be recognized for either book or tax purposes are permanent differences (e.g., the dividends-received deduction). As a result, the effective tax rate reflected in the financial statements may differ from the statutory rate reflected in the tax return. Those differences that are reported in different years for book and tax purposes are temporary and will reverse over time (e.g., the valuation of future policy benefits). These temporary differences are accounted for in the intervening periods as deferred tax assets and liabilities. Deferred tax assets generally represent revenue that is taxable before it is recognized in financial income and expenses that are deductible after they are recognized in financial income. Deferred tax liabilities generally represent revenues that are taxable after they are recognized in financial income or expenses or losses that are deductible before they are recognized in financial income. Components of accumulated other comprehensive income (loss) ("AOCI") are presented net of tax, and it is the Company's policy to use the aggregate portfolio approach to clear the disproportionate tax effects that remain in AOCI as a result of tax rate changes and certain other events. Under the aggregate portfolio approach, disproportionate tax effects are cleared only when the portfolio of investments that gave rise to the deferred tax item is sold or otherwise disposed of in its entirety. The application of GAAP requires the Company to evaluate the recoverability of the Company’s deferred tax assets and establish a valuation allowance, if necessary, to reduce the Company’s deferred tax assets to an amount that is more likely than not to be realized. Considerable judgment is required in determining whether a valuation allowance is necessary, and if so, the amount of such valuation allowance. In evaluating the need for a valuation allowance the Company may consider many factors, including: (1) the nature of the deferred tax assets and liabilities; (2) whether they are ordinary or capital; (3) in which tax jurisdictions they were generated and the timing of their reversal; (4) taxable income in prior carryback years as well as projected taxable earnings exclusive of reversing temporary differences and carryforwards; (5) the length of time that carryovers can be utilized in the various taxing jurisdictions; (6) any unique tax rules that would impact the utilization of the deferred tax assets; and (7) any tax planning strategies that the Company would employ to avoid a tax benefit from expiring unused. Although realization is not assured, management believes it is more likely than not that the deferred tax assets, net of valuation allowances, will be realized. GAAP prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that a company has taken or expects to take on tax returns. The application of this guidance is a two-step process, the first step being recognition. The Company determines whether it is more likely than not, based on the technical merits, that the tax position will be sustained upon examination. If a tax position does not meet the more likely than not recognition threshold, the benefit of that position is not recognized in the financial statements. The second step is measurement. The Company measures the tax position as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate resolution with a taxing authority that has full knowledge of all relevant information. This measurement considers the amounts and probabilities of the outcomes that could be realized upon ultimate settlement using the facts, circumstances, and information available at the reporting date. The Company’s liability for income taxes includes the liability for unrecognized tax benefits, interest and penalties which relate to tax years still subject to review by the Internal Revenue Service (“IRS”) or other taxing jurisdictions. Audit periods remain open for review until the statute of limitations expires. Generally, for tax years which produce net operating losses, capital losses or tax credit carryforwards, the statute of limitations does not close until the expiration of the statute of limitations for the tax year in which they are fully utilized. The completion of review or the expiration of the statute of limitations for a given audit period could result in an adjustment to the liability for income taxes. The Company classifies all interest and penalties related to tax uncertainties as income tax expense.
Variable Interest Entities	Variable Interest Entities The Company holds certain investments in entities in which its ownership interests could possibly be considered variable interests under Topic 810 of the FASB ASC (excluding debt and equity securities held as trading, available-for-sale, or held-to-maturity). The Company reviews the characteristics of each of these applicable entities and compares those characteristics to applicable criteria to determine whether the entity is a Variable Interest Entity ("VIE"). If the entity is determined to be a VIE, the Company then performs a detailed review to determine whether the interest would be considered a variable interest under the guidance. The Company then performs a qualitative review of all variable interests with the entity and determines whether the Company is the primary beneficiary. ASC 810 provides that an entity is the primary beneficiary of a VIE if the entity has 1) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance, and 2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.
Policyholder Liabilities, Revenues and Benefits Expense	Liabilities for life and annuity benefit reserves consist of liabilities for traditional life insurance, cash values associated with universal life insurance, immediate annuity benefit reserves, and other benefits associated with life and annuity benefits. The unpaid life claim liabilities consist of current pending claims as well as an estimate of incurred but not reported life insurance claims. Other policy benefit reserves consist of certain health insurance policies that are in runoff. The unpaid claim liabilities associated with other policy benefits includes current pending claims, the present value of estimated future claim payments for policies currently receiving benefits and an estimate of claims incurred but not yet reported. Traditional Life, Health, and Credit Insurance Products Traditional life insurance products consist principally of those products with fixed and guaranteed premiums and benefits, and they include whole life insurance policies, term and term-like life insurance policies, limited payment life insurance policies, and certain annuities with life contingencies. In accordance with ASC 805, the liabilities for future policy benefits on traditional life insurance products, when combined with the associated VOBA, were recorded at fair value on the date of the Merger. These values were computed using assumptions that include interest rates, mortality, lapse rates, expense estimates, and other assumptions based on the Company's experience, modified as necessary to reflect anticipated trends and to include provisions for possible adverse deviation. Liabilities for future policy benefits on traditional life insurance products have been computed using a net level method including assumptions as to investment yields, mortality, persistency, and other assumptions based on the Company's experience, modified as necessary to reflect anticipated trends and to include provisions for possible adverse deviation . Reserve investment yield assumptions on December 31, 2017 (Successor Company), range from approximately 2.75% to 4.50% . The liability for future policy benefits and claims on traditional life, health, and credit insurance products inclu des estimated unpaid claims that have been reported to us and claims incurred but not yet reported. Policy claims are charged to expense in the period in which the claims are incurred. Traditional life insurance premiums are recognized as revenue when due. Health and credit insurance premiums are recognized as revenue over the terms of the policies. Benefits and expenses are associated with earned premiums so that profits are recognized over the life of the contracts. This is accomplished by means of the provision for liabilities for future policy benefits and the amortization of DAC and VOBA. Gross premiums in excess of net premiums related to immediate annuities are deferred and recognized over the life of the policy. Universal Life and Investment Products Universal life and investment products include universal life insurance, guaranteed investment contracts, guaranteed funding agreements, deferred annuities, and annuities without life contingencies. Premiums and policy fees for universal life and investment products consist of fees that have been assessed against policy account balances for the costs of insurance, policy administration, and surrenders. Such fees are recognized when assessed and earned. Benefit reserves for universal life and investment products represent policy account balances before applicable surrender charges plus certain deferred policy initiation fees that are recognized in income over the term of the policies. Policy benefits and claims that are charged to expense include benefit claims incurred in the period in excess of related policy account balances and interest credited to policy account balances. Interest rates credited to universal life products ranged from 1.0% to 8.75% and investment products ranged from 0.5% to 11.3% in 2017 . The Company establishes liabilities for fixed indexed annuity ("FIA") products. These products are deferred fixed annuities with a guaranteed minimum interest rate plus a contingent return based on equity market performance. The FIA product is considered a hybrid financial instrument under the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") Topic 815 - Derivatives and Hedging which allows the Company to make the election to value the liabilities of these FIA products at fair value. This election was made for the FIA products issued prior to 2010 as the policies were issued. These products are no longer being marketed. The future changes in the fair value of the liability for these FIA products are recorded in Benefit and settlement expenses with the liability being recorded in Annuity account balances . For more information regarding the determination of fair value of annuity account balances please refer to Note 6, Fair Value of Financial Instruments . Premiums and policy fees for these FIA products consist of fees that have been assessed against the policy account balances for surrenders. Such fees are recognized when assessed and earned. The Company currently markets a deferred fixed annuity with a guaranteed minimum interest rate plus a contingent return based on equity market performance and the products are considered hybrid financial instruments under the FASB's ASC Topic 815 - Derivatives and Hedging . The Company did not elect to value these FIA products at fair value. As a result, the Company accounts for the provision that provides for a contingent return based on equity market performance as an embedded derivative. The embedded derivative is bifurcated from the host contract and recorded at fair value in Other liabilities . Changes in the fair value of the embedded derivative are recorded in Realized investment gains (losses) - Derivative financial instruments . For more information regarding the determination of fair value of the FIA embedded derivative refer to Note 6, Fair Value of Financial Instruments . The host contract is accounted for as a debt instrument in accordance with ASC Topic 944 - Financial Services—Insurance and is recorded in Annuity account balances with any discount to the minimum account value being accreted using the effective yield method. Benefits and settlement expenses include accreted interest and benefit claims incurred during the period. The Company markets universal life products with a guaranteed minimum interest rate plus a contingent return based on equity market performance and the products are considered hybrid financial instruments under the FASB's ASC Topic 815 - Derivatives and Hedging . The Company did not elect to value these indexed universal life ("IUL") products at fair value prior to the Merger date. As a result, the Company accounts for the provision that provides for a contingent return based on equity market performance as an embedded derivative. The embedded derivative is bifurcated from the host contract and recorded at fair value in Other liabilities . Changes in the fair value of the embedded derivative are recorded in Realized investment gains (losses) - Derivative financial instruments . For more information regarding the determination of fair value of the IUL embedded derivative refer to Note 7, Fair Value of Financial Instruments . The host contract is accounted for as a debt instrument in accordance with ASC Topic 944 - Financial Services - Insurance and is recorded in Future policy benefits and claims with any discount to the minimum account value being accreted using the effective yield method. Benefits and settlement expenses include accreted interest and benefit claims incurred during the period. The Company's accounting policies with respect to variable universal life ("VUL") and VA are identical except that policy account balances (excluding account balances that earn a fixed rate) are valued at fair value and reported as components of assets and liabilities related to separate accounts. The Company establishes liabilities for guaranteed minimum death benefits ("GMDB") on its VA products. The methods used to estimate the liabilities employ assumptions about mortality and the performance of equity markets. The Company assumes age-based mortality from the Ruark 2015 ALB table adjusted for company experience. Future declines in the equity market would increase the Company's GMDB liability. Differences between the actual experience and the assumptions used result in variances in profit and could result in losses. Our GMDB, as of December 31, 2017 (Successor Company), are subject to a dollar-for-dollar reduction upon withdrawal of related annuity deposits on contracts issued prior to January 1, 2003. The Company reinsures certain risks associated with the GMDB to Shades Creek. As of December 31, 2017 (Successor Company), the GMDB reserve, including the impact of reinsurance, was $26.6 million . Property and Casualty Insurance Products Property and casualty insurance products include service contract business, surety bonds, and guaranteed asset protection ("GAP"). Premiums for service contracts and GAP products are recognized based on expected claim patterns. For all other products, premiums are generally recognized over the terms of the contract on a pro-rata basis. Fee income from providing administrative services is recognized as earned when the related services are performed. Unearned premium reserves are maintained for the portion of the premiums that is related to the unexpired period of the policy. Benefit reserves are recorded when insured events occur. Benefit reserves include case basis reserves for known but unpaid claims as of the balance sheet date as well as incurred but not reported ("IBNR") reserves for claims where the insured event has occurred but has not been reported to the Company as of the balance sheet date. The case basis reserves and IBNR are calculated based on historical experience and on assumptions relating to claim severity and frequency, the level of used vehicle prices, and other factors. These assumptions are modified as necessary to reflect anticipated trends.
Reinsurance	Reinsurance The Company uses reinsurance extensively in certain of its segments and accounts for reinsurance and the recognition of the impact of reinsurance costs in accordance with the ASC Financial Services - Insurance Topic. The following summarizes some of the key aspects of the Company's accounting policies for reinsurance. Reinsurance Accounting Methodology —Ceded premiums of the Company's traditional life insurance products are treated as an offset to direct premium and policy fee revenue and are recognized when due to the assuming company. Ceded claims are treated as an offset to direct benefits and settlement expenses and are recognized when the claim is incurred on a direct basis. Ceded policy reserve changes are also treated as an offset to benefits and settlement expenses and are recognized during the applicable financial reporting period. Expense allowances paid by the assuming companies which are allocable to the current period are treated as an offset to other operating expenses. Since reinsurance treaties typically provide for allowance percentages that decrease over the lifetime of a policy, allowances in excess of the "ultimate" or final level allowance are capitalized. Amortization of capitalized reinsurance expense allowances representing recovery of acquisition costs is treated as an offset to direct amortization of DAC or VOBA. Amortization of deferred expense allowances is calculated as a level percentage of expected premiums in all durations given expected future lapses and mortality and accretion due to interest. The Company utilizes reinsurance on certain short duration insurance contracts (primarily issued through the Asset Protection segment). As part of these reinsurance transactions the Company receives reinsurance allowances which reimburse the Company for acquisition costs such as commissions and premium taxes. A ceding fee is also collected to cover other administrative costs and profits for the Company. As a component of reinsurance costs, reinsurance allowances are accounted for in accordance with the relevant provisions of ASC Financial Services—Insurance Topic, which state that reinsurance costs should be amortized over the contract period of the reinsurance if the contract is short-duration. Accordingly, reinsurance allowances received related to short-duration contracts are capitalized and charged to expense in proportion to premiums earned. Ceded unamortized acquisition costs are netted with direct unamortized acquisition costs in the balance sheet. Ceded premiums and policy fees on the Company's fixed universal life ("UL"), VUL, bank-owned life insurance ("BOLI"), and annuity products reduce premiums and policy fees recognized by the Company. Ceded claims are treated as an offset to direct benefits and settlement expenses and are recognized when the claim is incurred on a direct basis. Ceded policy reserve changes are also treated as an offset to benefits and settlement expenses and are recognized during the applicable valuation period. Since reinsurance treaties typically provide for allowance percentages that decrease over the lifetime of a policy, allowances in excess of the "ultimate" or final level allowance are capitalized. Amortization of capitalized reinsurance expense allowances are amortized based on future expected gross profits. Assumptions regarding mortality, lapses, and interest rates are continuously reviewed and may be periodically changed. These changes will result in "unlocking" that changes the balance in the ceded deferred acquisition cost and can affect the amortization of DAC and VOBA. Ceded unearned revenue liabilities are also amortized based on expected gross profits. Assumptions are based on the best current estimate of expected mortality, lapses and interest spread. The Company has also assumed certain policy risks written by other insurance companies through reinsurance agreements. Premiums and policy fees as well as Benefits and settlement expenses include amounts assumed under reinsurance agreements and are net of reinsurance ceded. Assumed reinsurance is accounted for in accordance with ASC Financial Services—Insurance Topic. Reinsurance Allowances—Long-Duration Contracts —Reinsurance allowances are intended to reimburse the ceding company for some portion of the ceding company's commissions, expenses, and taxes. The amount and timing of reinsurance allowances (both first year and renewal allowances) are contractually determined by the applicable reinsurance contract and do not necessarily bear a relationship to the amount and incidence of expenses actually paid by the ceding company in any given year. Ultimate reinsurance allowances are defined as the lowest allowance percentage paid by the reinsurer in any policy duration over the lifetime of a universal life policy (or through the end of the level term period for a traditional life policy). Ultimate reinsurance allowances are determined during the negotiation of each reinsurance agreement and will differ between agreements. The Company determines its "cost of reinsurance" to include amounts paid to the reinsurer (ceded premiums) net of amounts reimbursed by the reinsurer (in the form of allowances). As noted within ASC Financial Services—Insurance Topic, "The difference, if any, between amounts paid for a reinsurance contract and the amount of the liabilities for policy benefits relating to the underlying reinsured contracts is part of the estimated cost to be amortized". The Company's policy is to amortize the cost of reinsurance over the life of the underlying reinsured contracts (for long-duration policies) in a manner consistent with the way in which benefits and expenses on the underlying contracts are recognized. For the Company's long-duration contracts, it is the Company's practice to defer reinsurance allowances as a component of the cost of reinsurance and recognize the portion related to the recovery of acquisition costs as a reduction of applicable unamortized acquisition costs in such a manner that net acquisition costs are capitalized and charged to expense in proportion to net revenue recognized. The remaining balance of reinsurance allowances are included as a component of the cost of reinsurance and those allowances which are allocable to the current period are recorded as an offset to operating expenses in the current period consistent with the recognition of benefits and expenses on the underlying reinsured contracts. This practice is consistent with the Company's practice of capitalizing direct expenses (e.g. commissions), and results in the recognition of reinsurance allowances on a systematic basis over the life of the reinsured policies on a basis consistent with the way in which acquisition costs on the underlying reinsured contracts would be recognized. In some cases reinsurance allowances allocable to the current period may exceed non-deferred direct costs, which may cause net other operating expenses (related to specific contracts) to be negative. Amortization of Reinsurance Allowances —Reinsurance allowances do not affect the methodology used to amortize DAC and VOBA, or the period over which such DAC and VOBA are amortized. Reinsurance allowances offset the direct expenses capitalized, reducing the net amount that is capitalized. DAC and VOBA on traditional life policies are amortized based on the pattern of estimated gross premiums of the policies in force. Reinsurance allowances do not affect the gross premiums, so therefore they do not impact traditional life amortization patterns. DAC and VOBA on universal life products are amortized based on the pattern of estimated gross profits of the policies in force. Reinsurance allowances are considered in the determination of estimated gross profits, and therefore do impact amortization patterns. Reinsurance Assets and Liabilities —Claim liabilities and policy benefits are calculated consistently for all policies, regardless of whether or not the policy is reinsured. Once the claim liabilities and policy benefits for the underlying policies are estimated, the amounts recoverable from the reinsurers are estimated based on a number of factors including the terms of the reinsurance contracts, historical payment patterns of reinsurance partners, and the financial strength and credit worthiness of reinsurance partners and recorded as Reinsurance receivables on the balance sheet. The reinsurance receivables as of the Merger date, were recorded in the balance sheet using current accounting policies and the most current assumptions. As of the Merger date, the Company also calculated the ceded VOBA associated with the reinsured policies. The reinsurance receivables combined with the associated ceded VOBA represent the fair value of the reinsurance assets as of the Merger date. Liabilities for unpaid reinsurance claims are produced from claims and reinsurance system records, which contain the relevant terms of the individual reinsurance contracts. The Company monitors claims due from reinsurers to ensure that balances are settled on a timely basis. Incurred but not reported claims are reviewed to ensure that appropriate amounts are ceded. The Company analyzes and monitors the credit worthiness of each of its reinsurance partners to minimize collection issues. For newly executed reinsurance contracts with reinsurance companies that do not meet predetermined standards, the Company requires collateral such as assets held in trusts or letters of credit. Components of Reinsurance Cost —The following income statement lines are affected by reinsurance cost: Premiums and policy fees ("reinsurance ceded" on the Company's financial statements) represent consideration paid to the assuming company for accepting the ceding company's risks. Ceded premiums and policy fees increase reinsurance cost. Benefits and settlement expenses include incurred claim amounts ceded and changes in ceded policy reserves. Ceded benefits and settlement expenses decrease reinsurance cost. Amortization of deferred policy acquisition cost and VOBA reflects the amortization of capitalized reinsurance allowances representing recovery of acquisition costs. Ceded amortization decreases reinsurance cost. Other expenses include reinsurance allowances paid by assuming companies to the Company less amounts representing recovery of acquisition costs. Reinsurance allowances decrease reinsurance cost. The Company's reinsurance programs do not materially impact the other income line of the Company's income statement. In addition, net investment income generally has no direct impact on the Company's reinsurance cost. However, it should be noted that by ceding business to the assuming companies, the Company forgoes investment income on the reserves ceded to the assuming companies. Conversely, the assuming companies will receive investment income on the reserves assumed which will increase the assuming companies' profitability on business assumed from the Company.
Accounting Pronouncements Recently Adopted And Not Yet Adopted	Accounting Pronouncements Recently Adopted Accounting Standards Update ("ASU") 2018-02: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This Update addresses an accounting issue in which previously recorded tax effects are stranded in accumulated other comprehensive income as a result of the change in the federal corporate income tax rate in the Tax Cuts and Jobs Act ("Tax Reform Act"). The Update allows reclassification from accumulated other comprehensive income to retained earnings of such stranded tax effects. The amount of the reclassification is equal to the difference between the historical corporate income tax rate and the newly enacted corporate income tax rate. The Update is effective for annual and interim periods beginning after December 15, 2018, and early adoption is permitted. The Company elected to adopt the amendments in this Update on a retrospective basis, upon issuance, and recorded an entry as of December 31, 2017 to reclassify stranded tax effects from accumulated other comprehensive income to retained earnings in the amount of $26.3 million . ASU No. 2017-04-Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This Update simplifies the goodwill impairment test by re-defining the concept of goodwill impairment as the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The Update eliminates “Step 2” of the current goodwill impairment test, which requires entities to determine goodwill impairment by calculating the implied fair value of goodwill by remeasuring to fair value the assets and liabilities of a reporting unit as if that reporting unit had been acquired in a business combination. The Company elected to adopt the amendments in the Update in the first quarter of 2017, and applied the revised guidance to impairment tests conducted after January 1, 2017. Application of the revised guidance did not impact the Company’s financial position or results of operations. For more details regarding the Company’s goodwill assessment process, please refer to Note 11, Goodwill . ASU No. 2015-09 - Financial Services-Insurance (Topic 944): Disclosures about Short-Duration Contracts. The amendments in this Update require additional disclosures for short-duration contracts issued by insurance entities. The additional disclosures focus on the liability for unpaid claims and claim adjustment expenses and include incurred and paid claims development information by accident year in tabular form, along with a reconciliation of this information to the statement of financial position. For accident years included in the development tables, the amendments also require disclosure of the total incurred-but-not-reported liabilities and expected development on reported claims, along with claims frequency information unless impracticable. Finally, the amendments require disclosure of the historical average annual percentage payout of incurred claims. With the exception of the current reporting period, claims development information may be presented as supplementary information. The Update is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. The additional disclosures introduced in this Update have not been provided, as the short-duration lines of business to which they apply are not material to the Company’s financial statements. Accounting Pronouncements Not Yet Adopted ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606). This Update provides for significant revisions to the recognition of revenue from contracts with customers across various industries. Under the new guidance, entities are required to apply a prescribed 5-step process 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 or services. The accounting for revenues associated with insurance products is not within the scope of this Update. The Update was originally effective for annual and interim periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU No. 2015-14 - Revenues from Contracts with Customers: Deferral of the Effective Date , to defer the effective date of ASU No. 2014-09 by one year to annual and interim periods beginning after December 15, 2017. The Company will adopt this Update using the modified retrospective approach via a cumulative effect adjustment to retained earnings as of January 1, 2018. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, will impact certain revenues associated with the Company's Asset Protection products. Specifically, the Company will revise its pattern of recognition of administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. In consideration of the amendments in ASU 2014-09, the Company will recognize these fees based on expected claim patterns. The cumulative effect adjustment as of January 1, 2018 will result in a decrease in retained earnings of $88.6 million . The pre-tax cumulative effect adjustment was consistent with the Company's previous estimates, as disclosed in its Form 10-Q for the period ended September 30, 2017. However, the reduction in the federal corporate income tax rate due to the enactment of the Tax Reform Act resulted in an increase in the net impact to retained earnings. ASU No. 2016-01 - Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most notably, the Update requires that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) be measured at fair value with changes in fair value recognized in net income. The Update also introduces a single-step impairment model for equity investments without a readily determinable fair value. Additionally, the Update requires changes in instrument-specific credit risk for fair value option liabilities to be recorded in other comprehensive income. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2017 and will be applied on a modified retrospective basis. The Company recorded a cumulative-effect adjustment as of the date of adoption, January 1, 2018, transferring unrealized gains and losses on available-for-sale equity securities to retained earnings from accumulated other comprehensive income. The impact of this adjustment, net of income tax, resulted in a $10.7 million increase to retained earnings. The Company will make updates to its disclosures in the first quarter in order to comply with the new guidance. ASU No. 2016-02 - Leases. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of leases. The most significant change will relate to the accounting model used by lessees. The Update will require all leases with terms greater than 12 months to be recorded on the balance sheet in the form of a lease asset and liability. The lease asset and liability will be measured at the present value of the minimum lease payments less any upfront payments or fees. The Update also requires numerous disclosure changes for which the Company is assessing the impact. The amendments in the Update are effective for annual and interim periods beginning after December 15, 2018 on a modified retrospective basis. The Company has completed an inventory of all leases in the organization and is currently assessing the impact of the Update and updating internal processes to ensure compliance with the revised guidance. ASU No. 2016-13 - Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this Update introduce a new current expected credit loss (“CECL”) model for certain financial assets, including mortgage loans and reinsurance receivables. The new model will not apply to debt securities classified as available-for-sale. For assets within the scope of the new model, an entity will recognize as an allowance against earnings its estimate of the contractual cash flows not expected to be collected on day one of the asset’s acquisition. The allowance may be reversed through earnings if a security recovers in value. This differs from the current impairment model, which requires recognition of credit losses when they have been incurred and recognizes a security’s subsequent recovery in value in other comprehensive income. The Update also makes targeted changes to the current impairment model for available-for-sale debt securities, which comprise the majority of the Company’s invested assets. Similar to the CECL model, credit loss impairments will be recorded in an allowance against earnings that may be reversed for subsequent recoveries in value. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2019 on a modified retrospective basis. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption, and assessing the impact this standard will have on its operations and financial results. ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include: Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2017 using the retrospective method. There will be no financial impact on adoption while the Company expects a minor operational impact to cash flow statement reporting. ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. There will be no impact to the Company on adoption. ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the Update provide a specific test by which an entity may determine whether an acquisition involves a set of assets or a business. The amendments in the Update are to be applied prospectively for periods beginning after December 15, 2017. The Company has reviewed the revised requirements, and does not anticipate that the changes will impact its policies or recent conclusions related to its acquisition activities. ASU No. 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this update require entities to disaggregate the current-service-cost component from other components of net benefit cost and present it with other current compensation costs in the income statement. The other components of net benefit cost must be presented outside of income from operations if that subtotal is presented. In addition, the Update requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. As provided for in the ASU, the Company expects to apply the provisions of the statement retrospectively for components of net periodic pension costs and prospectively for capitalization of the service costs component of net periodic costs and net periodic postretirement benefits. The Update will not impact the Company’s financial position, results of operations, or current disclosures. ASU No. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine the financial and operational impact of implementing the Update, as well as to determine whether early adoption of the revised guidance is practicable. ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update are designed to permit hedge accounting to be applied to a broader range of hedging strategies as well as to more closely align hedge accounting and risk management objectives. Specific provisions include requiring changes in the fair value of a hedging instrument be recorded in the same income statement line as the hedged item when it affects earnings. In addition, after a hedge has initially qualified as an effective hedge the Update permits the use of a qualitative hedge effectiveness test in subsequent periods. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact this standard will have on its operations and financial results.
