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. During the fourth quarter of 2018, the Company identified certain cash flows that were incorrectly classified in the Company’s historical consolidated statements of cash flows. The Company has determined that these misclassifications were not material to the financial statements for any period. These amounts have been corrected in the comparative consolidated statements of cash flows for the nine months ended September 30, 2019. The nine months ended September 30, 2018 amounts have been revised resulting in an increase in operating cash flows and corresponding decrease in financing cash flows of $88.0 million compared to the amounts previously reported. Entities Included The consolidated condensed financial statements in this report 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. During the second quarter of 2019, the Company recorded an adjustment related to prior periods to correct an error pertaining to the deferred policy acquisition costs (“DAC”) tax reimbursements paid under reinsurance agreements the Company entered in previous years. The adjustment resulted in an $8.96 million increase to accounts and premiums receivable on the Company’s consolidated balance sheet, with a corresponding increase to income. The Company concluded that the adjustment was not quantitatively or qualitatively material to previously reported periods or the current interim period. As a result, this adjustment was recorded by the Company within the consolidated condensed financial statements as of and for the period ended June 30, 2019.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Significant Accounting Policies For a full description of significant accounting policies, see Note 2 to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. There were no significant changes to the Company’s accounting policies during the nine months ended September 30, 2019. Accounting Pronouncements Recently Adopted Accounting Standards Update (“ASU” or “Update”) No. 2016-02 - Leases. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of leases. The most significant change relates to the accounting model used by lessees. The Update requires 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 are measured at the present value of the minimum lease payments less any upfront payments or fees. The amendments in the Update became effective for annual and interim periods beginning after December 15, 2018 on a modified retrospective basis. The Company recorded a cumulative effect adjustment as of the date of adoption, January 1, 2019, establishing a right of use asset and lease liability of $18.2 million on its consolidated condensed balance sheet reflected in the property and equipment and other liabilities line items, respectively. 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 previous guidance, under which premiums are amortized to the maturity date of the security. The amendments became effective for annual and interim periods beginning after December 15, 2018. The Company recorded a cumulative effect adjustment as of the adoption date, January 1, 2019, resulting in a $50.8 million reduction to retained earnings, net of income tax. 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 became effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. At adoption, January 1, 2019, this standard did not have an impact on the Company’s operations or financial results. Accounting Pronouncements Not Yet Adopted 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, along with related amendments in ASU No. 2018-19 - Codification Improvements to Topic 326, Financial Instruments-Credit Losses, are effective for annual and interim periods beginning after December 15, 2019 on a modified retrospective basis. The Company has completed its scoping and gap analysis with respect to the implementation of the new standard. Additionally, the Company is in the testing phase with respect to its calculation of the allowance for credit losses for its portfolio of commercial mortgage loans and mortgage loan commitments and reinsurance receivables. A vendor-sourced credit loss model will be used to measure the allowance for the majority of the Company’s commercial mortgage loans and unfunded mortgage loan commitments, and the Company will use an internally-developed calculation to measure the allowance for reinsurance receivables. Testing and review activities which have not yet been completed include final user acceptance testing of the vendor model for commercial mortgage loans, as well as final approval of certain model inputs such as economic forecasts and mean reversion parameters which will materially impact the final allowance. The Company is on track to complete its testing and assumption review in the fourth quarter. In addition to development and testing of the calculation of the allowance for credit losses for these assets, the Company continues to implement new processes and controls with respect to the measurement and recognition of the allowance, along with the additional disclosures required by the Update. The Company expects to record a cumulative effect adjustment which includes an additional allowance for credit losses for commercial mortgage loans and reinsurance receivables. The amount of the cumulative effect adjustment cannot yet be reasonably estimated, as the allowance for credit losses recorded as of January 1, 2020 may be materially impacted by a) model inputs that have not been finalized or b) changes in macroeconomic conditions or other events and circumstances that cannot be reasonably forecasted. ASU No. 2018-12 - Financial Services - Insurance (Topic 944): Targeted Improvements to Accounting for Long-Duration Contracts. The amendments in this Update are designed to make improvements to the existing recognition, measurement, presentation, and disclosure requirements for certain long-duration contracts issued by an insurance company. The new amendments require insurance entities to provide a more current measure of the liability for future policy benefits for traditional and limited-payment contracts by regularly refining the liability for actual past experience and updated future assumptions. This differs from current requirements where assumptions are locked-in at contract issuance for these contract types. In addition, the updated liability will be discounted using an upper-medium grade (low-credit-risk) fixed income instrument yield that reflects the characteristics of the liability which differs from currently used rates based on the invested assets supporting the liability. In addition, the amendments introduce new requirements to assess market-based insurance contract options and guarantees for Market Risk Benefits and measure them at fair value. This Update also requires insurance entities to amortize deferred acquisition costs on a constant-level basis over the expected life of the contract. Finally this Update requires new disclosures including liability rollforwards and information about significant inputs, judgments, assumptions, and methods used in the measurement. The amendments in this Update are currently effective for annual and interim periods beginning after December 15, 2020 with early adoption permitted. However, in October 2019, the Financial Accounting Standards Board (the “FASB”) affirmed their previous decision to delay the effective date of the Update by one year for larger SEC filers and two or three years for others, with early adoption permitted. A final Update is currently being drafted and when issued will extend the implementation deadline for the Company by one year to periods beginning after December 15, 2021. The Company has started its implementation efforts and is currently reviewing its policies, processes, and applicable systems to determine the impact this standard will have on its operations and financial results. While it is not possible to estimate the expected impact of adoption at this time, given the nature and extent of the required changes to a significant portion of the Company’s operations, adoption is expected to have a significant impact on our consolidated financial statements and related disclosures and will require changes to certain of our processes, systems, and controls. ASU No. 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40). The amendments in this update require customers in a cloud computing arrangement accounted for as a service contract to capitalize implementation costs incurred in the arrangement . Capitalization should be based on the nature of the costs and the project stage at which the cost was incurred. The amendments in the Update are effective for annual and interim periods beginning after December 15, 2019 on either a retrospective or prospective basis. There will be no impact at the adoption date as the Company will adopt the amendments on a prospective basis.

Business Combinations [Abstract]
SIGNIFICANT TRANSACTIONS	SIGNIFICANT TRANSACTIONS The Lincoln National Life Insurance Company On May 1, 2018, The Lincoln National Life Insurance Company (“Lincoln Life”) completed its previously announced acquisition (the “Liberty Closing”) of Liberty Mutual Group Inc.’s (“Liberty Mutual”) Group Benefits Business and Individual Life and Annuity Business (the “Life Business”) through the acquisition of all of the issued and outstanding capital stock of Liberty Life Assurance Company of Boston (“Liberty”). In connection with the Liberty Closing and pursuant to the Master Transaction Agreement, dated January 18, 2018 (the “Master Transaction Agreement”), the Company and Protective Life and Annuity Insurance Company (“PLAIC”), a wholly owned subsidiary of the Company, entered into reinsurance agreements (the “Liberty Reinsurance Agreements”) and related ancillary documents (including administrative services agreements and transition services agreements) providing for the reinsurance and administration of the Life Business. Pursuant to the Liberty Reinsurance Agreements, Liberty ceded to the Company and PLAIC the insurance policies related to the Life Business on a 100% coinsurance basis. The aggregate ceding commission for the reinsurance of the Life Business was $422.4 million, which is the purchase price. All policies issued in states other than New York were ceded to the Company under a reinsurance agreement between Liberty and the Company, and all policies issued in New York were ceded to PLAIC under a reinsurance agreement between Liberty and PLAIC. The aggregate statutory reserves of Liberty ceded to the Company and PLAIC as of the date of the Liberty Closing were approximately $13.2 billion, which amount was based on initial estimates. The final reserve amount determined, as adjusted during the measurement period, was $13.7 billion. In addition, there are certain pending items which remain subject to adjustment in accordance with the Master Transaction Agreement and could result in a gain in future periods. Pursuant to the terms of the Liberty Reinsurance Agreements, each of the Company and PLAIC are required to maintain assets in trust for the benefit of Liberty to secure their respective obligations to Liberty under the Liberty Reinsurance Agreements. The trust accounts were initially funded by each of the Company and PLAIC principally with the investment assets that were received from Liberty. Additionally, the Company and PLAIC have each agreed to provide, on behalf of Liberty, administration and policyholder servicing of the Life Business reinsured by it pursuant to administrative services agreements between Liberty and each of the Company and PLAIC. The terms of the Liberty Reinsurance Agreements resulted in an acquisition of the Life Business by the Company in accordance with Accounting Standards Codification ("ASC" or "Codification") Topic 805, Business Combinations . The following table details the purchase consideration and final allocation of assets acquired and liabilities from the Life Business reinsurance transaction as of the date of the Liberty Closing. Fair Value (Dollars In Thousands) ASSETS Fixed maturities $ 12,588,512 Mortgage loans 435,405 Policy loans 131,489 Total investments 13,155,406 Cash 35,179 Accrued investment income 152,030 Reinsurance receivables 272 Value of business acquired 379,717 Other assets 916 Total assets 13,723,520 LIABILITIES Future policy benefits and claims $ 11,751,895 Unearned premiums — Total policy liabilities and accruals 11,751,895 Annuity account balances 1,864,141 Other policyholders’ funds 41,936 Other liabilities 65,548 Total liabilities 13,723,520 NET ASSETS ACQUIRED $ — The following unaudited pro forma condensed consolidated results of operations assumes that the aforementioned transactions of the Life Business were completed as of January 1, 2017. The unaudited pro forma condensed results of operations are presented solely for information purposes and are not necessarily indicative of the consolidated condensed results of operations that might have been achieved had the transaction been completed as of the date indicated: Unaudited For The (Dollars In Thousands) Revenue $ 1,269,963 $ 3,826,859 Net income $ 78,524 $ 195,211 Great-West Life & Annuity Insurance Company On January 23, 2019, the Company entered into a Master Transaction Agreement (the “GWL&A Master Transaction Agreement”) with Great-West Life & Annuity Insurance Company (“GWL&A”), Great-West Life & Annuity Insurance Company of New York (“GWL&A of NY”), The Canada Life Assurance Company (“CLAC”) and The Great-West Life Assurance Company (“GWL” and, together with GWL&A, GWL&A of NY and CLAC, the “Sellers”), pursuant to which the Company will acquire via reinsurance (the “Transaction”) substantially all of the Sellers’ individual life insurance and annuity business (the “Individual Life Business”). On June 3, 2019, the Company and PLAIC completed the Transaction (the “GWL&A Closing”). Pursuant to the GWL&A Master Transaction Agreement, the Company and PLAIC entered into reinsurance agreements (the “GWL&A Reinsurance Agreements”) and related ancillary documents at the GWL&A Closing. On the terms and subject to the conditions of the GWL&A Reinsurance Agreements, the Sellers ceded to the Company and PLAIC, effective as of the date of the GWL&A Closing, substantially all of the insurance policies related to the Individual Life Business on a 100% indemnity basis net of reinsurance recoveries. The aggregate ceding commission for the reinsurance of the Individual Life Business paid at the GWL&A Closing was $765.7 million, which amount is subject to adjustment in accordance with the GWL&A Master Transaction Agreement. All policies issued in states other than New York were ceded to the Company under reinsurance agreements between the applicable Seller and the Company, and all policies issued in New York were ceded to PLAIC under a reinsurance agreement between GWL&A of NY and PLAIC. The aggregate statutory reserves of the Sellers ceded to the Company and PLAIC as of the GWL&A Closing were approximately $20.4 billion, which amount was based on initial estimates and is subject to adjustment following the GWL&A Closing. To support its obligations under the GWL&A Reinsurance Agreements, the Company established trust accounts for the benefit of GWL&A, CLAC and GWL, and PLAIC established a trust account for the benefit of GWL&A of NY. The Sellers retained a block of participating policies, which will be administered by PLC. As of the purchase date, the Company has recorded an estimate in the amount of $49.5 million related to contingent consideration. The final ceding commission is subject to adjustment based on these amounts. These amounts are accrued within other liabilities in the Company’s consolidated condensed balance sheet. The contingent consideration is comprised of a holdback provision and a post-closing sales adjustment. The holdback amount is related to the performance of certain blocks of business for a specified period of time after the close of the transaction. The range of amounts payable to Great West under this provision is $0 - $40 million. The Company established a liability of $37.6 million as of the transaction date, which represents the Company's best estimate of the present value of future payments. Great West is also entitled to a payment for certain post-closing sales occurring between June 1, 2019 and December 31, 2019. At this time, a range for this payment cannot be estimated and the Company established a liability of $11.9 million on the transaction date, which represents the Company's best estimate of the present value of future payments as of the transaction date. During the three months ended September 30, 2019, this estimate was revised based on sales and returns achieved during that period. The liability as of September 30, 2019 was $8.2 million, which represents the Company's best estimate of the present value of future payments. The reduction in the liability was recorded as a component of earnings. The GWL&A Master Transaction Agreement and other transaction documents contain certain customary representations and warranties made by each of the parties, and certain customary covenants regarding the Sellers and the Individual Life Business, and provide for indemnification, among other things, for breaches of those representations, warranties, and covenants. The terms of the GWL&A Reinsurance Agreements resulted in an acquisition of the Individual Life Business by PLC in accordance with ASC Topic 805, Business Combinations . The following table details the preliminary allocation of assets acquired and liabilities assumed from the Individual Life Business reinsurance transaction as of the date of the GWL&A Closing. The Company has not completed the process of determining the fair value of assets acquired and liabilities assumed, but will do so in the twelve month measurement period subsequent to the date of the GWL&A Closing. These estimates are provisional and subject to adjustment. Any adjustments to these fair value estimates will be reflected, retroactively, as of the date of the acquisition, and may result in adjustments to the value of business acquired.

MONY CLOSED BLOCK OF BUSINESS

MONY CLOSED BLOCK OF BUSINESS	9 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 accumulated other comprehensive income (loss) (“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 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 September 30, 2019 and December 31, 2018 is as follows: As of September 30, 2019 December 31, 2018 (Dollars In Thousands) Closed block liabilities Future policy benefits, policyholders’ account balances and other policyholder liabilities $ 5,579,389 $ 5,679,732 Policyholder dividend obligation 319,865 — Other liabilities 11,366 22,505 Total closed block liabilities 5,910,620 5,702,237 Closed block assets Fixed maturities, available-for-sale, at fair value $ 4,694,274 $ 4,257,437 Mortgage loans on real estate 73,563 75,838 Policy loans 648,805 672,213 Cash 75,828 116,225 Other assets 106,481 136,388 Total closed block assets 5,598,951 5,258,101 Excess of reported closed block liabilities over closed block assets 311,669 444,136 Portion of above representing accumulated other comprehensive income: Net unrealized investment gains (losses) net of policyholder dividend obligation: $198,285 and $(141,128); and net of income tax: $(41,640) and $61,676 — (120,528) Future earnings to be recognized from closed block assets and closed block liabilities $ 311,669 $ 323,608 Reconciliation of the policyholder dividend obligation is as follows: For The 2019 2018 (Dollars In Thousands) Policyholder dividend obligation, beginning of period $ — $ 160,712 Applicable to net revenue (losses) (19,548) (24,922) Change in net unrealized investment gains (losses) allocated to the policyholder dividend obligation 339,413 (135,790) Policyholder dividend obligation, end of period $ 319,865 $ — Closed Block revenues and expenses were as follows: For The For The 2019 2018 2019 2018 (Dollars In Thousands) Revenues Premiums and other income $ 37,652 $ 39,691 $ 115,202 $ 121,768 Net investment income 52,018 50,833 154,808 152,248 Net investment gains (losses) 1,104 40 693 66 Total revenues 90,774 90,564 270,703 274,082 Benefits and other deductions Benefits and settlement expenses 84,531 83,588 250,410 251,480 Other operating expenses 229 291 836 310 Total benefits and other deductions 84,760 83,879 251,246 251,790 Net revenues before income taxes 6,014 6,685 19,457 22,292 Income tax expense 1,263 1,404 4,086 4,681 Net revenues $ 4,751 $ 5,281 $ 15,371 $ 17,611

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 had a gross unrealized loss greater than twelve months of $5.5 million as of September 30, 2019. This category predominately includes student loan backed auction rate securities (“ARS”) whose underlying collateral is at least 1% 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 $1.7 million and $1.1 million as of September 30, 2019, respectively. These declines were related to changes in interest rates. The states, municipals, and political subdivisions category had gross unrealized losses greater than twelve months of $0.3 million as of September 30, 2019. The aggregate decline in fair 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. The corporate securities category had gross unrealized losses greater than twelve months of $279.5 million as of September 30, 2019. The aggregate decline in fair 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, interest rate movement, and other pertinent information. As of September 30, 2019, the Company had a total of 809 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, 2018: Less Than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized (Dollars In Thousands) Residential mortgage-backed securities $ 1,485,009 $ (31,302) $ 795,765 $ (30,633) $ 2,280,774 $ (61,935) Commercial mortgage-backed securities 419,420 (7,398) 1,405,690 (49,602) 1,825,110 (57,000) Other asset-backed securities 687,271 (30,963) 148,871 (4,435) 836,142 (35,398) U.S. government-related securities 130,290 (4,668) 1,085,654 (41,054) 1,215,944 (45,722) Other government-related securities 224,273 (15,207) 131,569 (18,583) 355,842 (33,790) States, municipals, and political subdivisions 1,004,262 (27,180) 1,129,152 (91,722) 2,133,414 (118,902) Corporate securities 18,225,656 (966,825) 12,824,024 (1,411,415) 31,049,680 (2,378,240) Redeemable preferred stocks 41,147 (4,467) 41,655 (7,093) 82,802 (11,560) $ 22,217,328 $ (1,088,010) $ 17,562,380 $ (1,654,537) $ 39,779,708 $ (2,742,547) As of September 30, 2019, the Company had securities in its available-for-sale portfolio which were rated below investment grade of $1.6 billion and had an amortized cost of $1.7 billion. In addition, included in the Company’s trading portfolio, the Company held $113.5 million of securities which were rated below investment grade. Approximately $235.2 million of the available-for-sale and trading securities that were below investment grade were not publicly traded.

The Company’s held-to-maturity securi ties had $141.0 million of gross unrecognized holding gains as of September 30, 2019. These held-to-maturity securities are issued by affiliates of the Company which are considered variable interest entities (“VIEs”). 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 $86.3 million of gross unrecognized holding losses as of December 31, 2018. 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. Variable Interest Entity The Company holds certain investments in an entity in which its ownership interests could possibly be considered variable interests under Topic 810 of the Financial Accounting Standards Board (“FASB”) Codification (excluding debt and equity securities held as trading, available-for-sale, or held-to-maturity). The Company reviews the characteristics of the applicable entity and compares those characteristics to applicable criteria to determine whether the entity is a 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”) as of September 30, 2019 and December 31, 2018, that was determined to be a VIE.

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; and 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 estimates 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 September 30, 2019: Measurement Level 1 Level 2 Level 3 Total (Dollars In Thousands) Assets: Fixed maturity securities - available-for-sale Residential mortgage-backed securities 4 $ — $ 5,340,664 $ — $ 5,340,664 Commercial mortgage-backed securities 4 — 2,704,831 9,635 2,714,466 Other asset-backed securities 4 — 1,482,414 416,062 1,898,476 U.S. government-related securities 4 801,931 360,276 — 1,162,207 State, municipals, and political subdivisions 4 — 4,834,657 — 4,834,657 Other government-related securities 4 — 603,236 — 603,236 Corporate securities 4 — 45,960,493 1,325,112 47,285,605 Redeemable preferred stocks 4 70,627 16,935 — 87,562 Total fixed maturity securities - available-for-sale 872,558 61,303,506 1,750,809 63,926,873 Fixed maturity securities - trading Residential mortgage-backed securities 3 — 202,963 — 202,963 Commercial mortgage-backed securities 3 — 208,935 — 208,935 Other asset-backed securities 3 — 76,205 61,527 137,732 U.S. government-related securities 3 25,756 22,356 — 48,112 State, municipals, and political subdivisions 3 — 300,331 — 300,331 Other government-related securities 3 — 26,792 — 26,792 Corporate securities 3 — 1,592,418 7,036 1,599,454 Redeemable preferred stocks 3 12,195 — — 12,195 Total fixed maturity securities - trading 37,951 2,430,000 68,563 2,536,514 Total fixed maturity securities 910,509 63,733,506 1,819,372 66,463,387 Equity securities 3 512,937 — 68,484 581,421 Other long-term investments (1) 3 & 4 62,772 567,702 193,040 823,514 Short-term investments 3 963,836 80,606 — 1,044,442 Total investments 2,450,054 64,381,814 2,080,896 68,912,764 Cash 3 223,300 — — 223,300 Assets related to separate accounts Variable annuity 3 12,542,212 — — 12,542,212 Variable universal life 3 1,066,999 — — 1,066,999 Total assets measured at fair value on a recurring basis $ 16,282,565 $ 64,381,814 $ 2,080,896 $ 82,745,275 Liabilities: Annuity account balances (2) 3 $ — $ — $ 71,820 $ 71,820 Other liabilities (1) 3 & 4 12,579 345,085 1,067,291 1,424,955 Total liabilities measured at fair value on a recurring basis $ 12,579 $ 345,085 $ 1,139,111 $ 1,496,775 (1) Includes certain freestanding and embedded derivatives.

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 91.5% 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, when available the Company obtains two quotes per security. Where multiple broker quotes are obtained, the Company reviews the quotes and selects the quote that provides the best estimate of the price a market participant would pay for these specific assets in an arm’s length transaction. 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. The Company’s assessment incorporates various metrics (yield curves, credit spreads, prepayment rates, etc.) along with other information available to the Company from both internal and external sources 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 nine months ended September 30, 2019. 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 September 30, 2019, the Company held $10.0 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 September 30, 2019, the Company held $487.2 million of Level 3 ABS, which included $425.7 million of other asset-backed securities classified as available-for-sale and $61.5 million of other asset-backed securities classified as trading. These securities 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 3 measurements due to the nature of the transaction. Corporate Securities, Redeemable Preferred Stocks, U.S. Government-Related Securities, States, Municipals, and Political Subdivisions, and Other Government-Related Securities As of September 30, 2019, the Company classified approximately $53.7 billion of corporate securities, redeemable preferred stocks, 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 September 30, 2019, the Company classified approximately $1.3 billion 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 September 30, 2019, the Company held approximately $68.5 million of equity securities classified as Level 3. Of this total, $68.5 million represents Federal Home Loan Bank (“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 September 30, 2019, 85% of derivatives based upon notional values were priced using exchange prices or independent broker quotations. The remaining derivatives were priced by pricing valuation models, which utilize observable market data inputs to the extent they are available. 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 are 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 condensed balance sheet. The changes in fair value are recorded in earnings as Realized investment gains (losses) . Refer to Note 7, Derivative Financial Instruments for more information related to each embedded derivatives gains and losses. The fair value of the guaranteed living withdrawal benefits (“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 87% - 100% based on company experience. 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). For expected lapse and utilization, assumptions are used and updated for actual experience, as necessary, using an internal predictive model developed by the Company. As a result of using significant unobservable inputs, the GLWB embedded derivative is categorized as Level 3. Policyholder assumptions are reviewed on an annual basis. The balance of the fixed indexed annuity (“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 are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the 2015 Ruark ALB mortality table with attained age factors varying from 87% - 100% based on company experience. 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 assumptions 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-based mortality from the SOA 2015 VBT Primary Tables, with attained age factors varying from 37% - 577% based on company experience. 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 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 where the Company has ceded certain blocks of policies are designated as “trading securities”; therefore changes in their fair value are also reported in earnings. As of September 30, 2019, the fair value of the embedded derivative is based upon the relationship between the statutory policy liabilities (net of policy loans) of $3.5 billion and the statutory unrealized gain (loss) of the securities of $285.9 million. As a result, changes in the fair value of the embedded derivatives where the Company has ceded certain blocks of policies 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. The Company and certain of its 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 September 30, 2019 was $103.2 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 Captive Insurance Company (“Golden Gate II”), a wholly owned subsidiary of the Company, 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 $49.5 million as of September 30, 2019. Golden Gate II recognized $1.0 million in gains related to payments made under this agreement for the nine months ended September 30, 2019. As of September 30, 2019, certain interest support agreement obligations to Golden Gate II of approximately $4.9 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 agreement. The YRT premium support agreements provide that PLC will make payments to Golden Gate Captive Insurance Company (“Golden Gate”), a wholly owned subsidiary of the Company, 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 September 30, 2019 was $50.9 million. Golden Gate II recognized $0.7 million in gains related to payments made under this agreement for the nine months ended September 30, 2019. The portfolio maintenance agreements provide that PLC will make payments to Golden Gate, Golden Gate V, and West Coast Life Insurance Company (“WCL”), a wholly owned subsidiary of the Company, 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 September 30, 2019, was $2.8 million. As of September 30, 2019, no payments have been made under these agreements. The Funds Withheld derivative results from a reinsurance agreement with Shades Creek Captive Insurance Company (“Shades Creek”), a direct wholly owned subsidiary of PLC, 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 September 30, 2019, was a liability of $93.7 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 September 30, 2019 is $71.8 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: Fair Value As of September 30, 2019 Valuation Unobservable Range (Dollars In Thousands) Assets: Other asset-backed securities $ 415,950 Liquidation Liquidation value $95.39 - $97.00 ($96.48) Discounted cash flow Liquidity premium 0.01% - 1.32% (0.44%) Paydown rate 9.96% - 12.61% (11.62%) Corporate securities 1,325,112 Discounted cash flow Spread over treasury 0.89% - 3.93% (1.73%) Liabilities: (1) Embedded derivatives - GLWB (2) 217,757 Actuarial cash flow model Mortality 87% to 100% of Lapse Internal Predictive Model Utilization Internal Predictive Model Nonperformance risk 0.12% - 0.97% Embedded derivative - FIA 308,861 Actuarial cash flow model Expenses $195 per policy Withdrawal rate 0.4% - 1.2% prior to age 70, 100% of the RMD for ages 70+ Mortality 87% to 100% of Ruark 2015 ALB table Lapse 0.5% - 50.0%, depending on duration/surrender charge period Dynamically adjusted for WB moneyness and projected market rates vs credited rates Nonperformance risk 0.12% - 0.97% Embedded derivative - IUL 141,793 Actuarial cash flow model Mortality 37% - 156% of 2015 VBT Primary Tables Lapse 0.5% - 10.0%, depending on duration/distribution channel and smoking class Nonperformance risk 0.12% - 0.97% (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 for which book value approximates fair value. The Company has considered all reasonably available quantitative inputs as of September 30, 2019, but the valuation techniques and inputs used by some brokers in pricing certain financial instruments are not shared with the Company. This resulted in $78.3 million of financial instruments being classified as Level 3 as of September 30, 2019. Of the $78.3 million, $71.3 million are other asset-backed securities and $

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 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 variable annuity (“VA”) contracts, fixed indexed annuities, and indexed universal life contracts: • 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. It is the Company's policy not to offset assets and liabilities associated with open derivative contracts. However, the Chicago Mercantile Exchange (“CME”) rules characterize variation margin transfers as settlement payments, as opposed to adjustments to collateral. As a result, derivative assets and liabilities associated with centrally cleared derivatives for which the CME serves as the central clearing party are presented as if these derivatives had been settled as of the reporting date. 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 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 flows paid on the note. • To hedge a floating rate note, the Company entered into an interest rate swap to exchange the floating rate on the note for a fixed rate in order to hedge the interest rate risk associated with the note. The cash flows received on the swap are identical to the cash flow variability 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 markets and overall volatility. • The Company markets certain fixed indexed annuity products. The FIA component is considered an embedded derivative as it is 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 as it is 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 and funds withheld 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 and funds withheld arrangements 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 10, Debt and Other Obligations for details of the Company’s repurchase agreement programs. Collateral received includes both cash and non-cash collateral. Cash collateral received by the Company is recorded on the consolidated condensed balance sheet as “cash”, with a corresponding amount recorded in “other liabilities” to represent the Company’s obligation to return the collateral. Non-cash collateral received by the Company is not recognized on the consolidated condensed balance sheet unless the Company exercises its right to sell or re-pledge the underlying asset. As of September 30, 2019 and December 31, 2018, the fair value of non-cash collateral received was $34.4 million and $45.0 million, respectively.

MORTGAGE LOANS

MORTGAGE LOANS	9 Months Ended

MORTGAGE LOANS
MORTGAGE LOANS	MORTGAGE LOANS Mortgage Loans The Company invests a portion of its investment portfolio in commercial mortgage loans. As of September 30, 2019, the Company’s mortgage loan holdings were appr oximately $9.3 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. Certain of the mortgage loans have call options that occur within the next 10 years. However, if interest rates were to significantly increase, the Company may be unable to exercise the call options on its existing mortgage loans commensurate with the significantly increased market rates. As of September 30, 2019, assuming the loans are called at their next call dates, approximately $54.4 million of principal would become due for the remainder of 2019, $850.9 million in 2020 through 2024 and $59.4 million in 2025 through 2029. 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 September 30, 2019 and December 31, 2018, approximately $757.4 million and $700.6 million, respectively, of the Company’s total mortgage loans principal balance have this participation feature. Cash flows received as a result of this participation feature are recorded as interest income. During the three and nine months ended September 30, 2019 and 2018, the Company recognized $3.8 million and $18.0 million and $9.5 million and $22.0 million, respectively, of participating mortgage loan income. As of September 30, 2019, $3.2 million of the Company’s 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 nine months ended September 30, 2019, the Company recognized four troubled debt restructurings as a result of granting concessions to borrowers which included loan terms unavailable from other lenders. During the three and nine months ended September 30, 2019, the Company did not recognize any mortgage loans that were foreclosed and were converted to real estate properties. The Company did not identify any loans whose principal was permanently impaired during the three and nine months ended September 30, 2019. As of September 30, 2019 and December 31, 2018, the Company had an allowance for mortgage loan credit losses of $4.1 million and $1.3 million, respectively. 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. As of September 30, 2019 and December 31, 2018, the Company had allowances for mortgage loan credit losses of $4.1 million and $1.3 million, respectively, which is shown in the chart below. As of September 30, 2019 December 31, 2018 (Dollars In Thousands) Beginning balance $ 1,296 $ — Charge offs (350) — Recoveries — (209) Provision 3,110 1,505 Ending balance $ 4,056 $ 1,296 It is the Company’s policy to cease to carry accrued 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. The carrying value of the delinquent loans is shown in the following chart. Greater 30-59 Days 60-89 Days than 90 Days Total As of September 30, 2019 Delinquent Delinquent Delinquent Delinquent (Dollars In Thousands) Commercial mortgage loans $ 1,641 $ — $ 730 $ 2,371 Number of delinquent commercial mortgage loans 2 — 3 5 As of December 31, 2018 Commercial mortgage loans $ 1,044 $ — $ 1,234 $ 2,278 Number of delinquent commercial mortgage loans 4 — 1 5 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 loans to 90 days of interest. Once accrued interest on a non-accrual loan is received, interest income is recognized on a cash basis. The following table includes the recorded investment, unpaid principal balance, related allowance, average recorded investment, interest income recognized, and cash basis interest income of the commercial loan portfolio as of September 30, 2019 and December 31, 2018.

DEBT AND OTHER OBLIGATIONS	DEBT AND OTHER OBLIGATIONS Under a revolving line of credit arrangement that was in effect until May 3, 2018 (the “2015 Credit Facility”), the Company had the ability to borrow on an unsecured basis up to an aggregate principal amount of $1.0 billion. The Company had the right in certain circumstances to request that the commitment under the 2015 Credit Facility be increased up to a maximum principal amount of $1.25 billion. Balances outstanding under the 2015 Credit Facility accrued interest at a rate equal to, at the option of the Borrowers, (i) LIBOR plus a spread based on the ratings of PLC’s Senior Debt, or (ii) the sum of (A) a rate equal to the highest of (x) the Administrative Agent’s Prime rate, (y) 0.50% above the Funds rate, or (z) the one-month LIBOR plus 1.0% and (B) a spread based on the ratings of PLC’s Senior Debt. The 2015 Credit Facility also provided for a facility fee at a rate that varies with the ratings of PLC’s Senior Debt and that is calculated on the aggregate amount of commitments under the 2015 Credit Facility, whether used or unused. The annual facility fee rate is 0.125% of the aggregate principal amount. The 2015 Credit Facility provides that PLC is liable for the full amount of any obligations for borrowings or letters of credit, including those of the Company, under the Credit Facility. The maturity date of the 2015 Credit Facility was February 2, 2020. On May 3, 2018, the Company amended the 2015 Credit Facility (as amended, the “Credit Facility”). Under the Credit Facility, the Company has the ability to borrow on an unsecured basis up to an aggregate principal amount of $1.0 billion. The Company has the right in certain circumstances to request that the commitment under the Credit Facility be increased up to a maximum principal amount of $1.5 billion. Balances outstanding under the Credit Facility accrue interest at a rate equal to, at the option of the Borrowers, (i) LIBOR plus a spread based on the ratings of PLC’s Senior Debt, or (ii) the sum of (A) a rate equal to the highest of (x) the Administrative Agent’s Prime rate, (y) 0.50% above the Funds Rate, or (z) the one-month LIBOR plus 1.0% and (B) a spread based on the ratings of PLC’s Senior Debt. The Credit Facility also provided for a facility fee at a rate that varies with the ratings of PLC’s Senior Debt and that is calculated on the aggregate amount of commitments under the Credit Facility, whether used or unused. The annual facility fee rate is 0.125% of the aggregate principal amount. The Credit Facility provides that PLC is liable for the full amount of any obligations for borrowings or letters of credit, including those of the Company, under the Credit Facility. The maturity date of the Credit Facility is May 3, 2023. The Company is not aware of any non-compliance with the financial debt covenants of the Credit Facility as of September 30, 2019. PLC had no outstanding balance as of September 30, 2019. During 2018, the Company issued $110.0 million of Subordinated Funding Obligations at a rate of 3.55% due 2038.

(3) Fixed rate obligations. 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 maturi ty securities, and the agreements provide for net settlement in the event of default or on termination of the agreements. As of September 30, 2019, the fair value of securities pledged under the repurchase program was $278.0 million, and the repurchase obligation of $272.1 million was included in the Company’s consolidated condensed balance sheets (at an average borrowing rate of 215 basis points). During the nine months ended September 30, 2019, the maximum balance outstanding at any one point in time related to these programs was $540.0 million. The average daily balance was $160.1 million (at an average borrowing rate of 242 basis points) during the nine months ended September 30, 2019. As of December 31, 2018, the fair value of securities pledged under the repurchase program wa s $451.9 million, and the repurchase obligation of $418.1 million w as included in the Company’s consolidated condensed balance sheets (at an average borrowing rate of 245 basis points). During 2018, the maximum balance outstanding at any one point in time related to these programs w as $885.0 million . The average daily balance was $511.4 million (at an average borrowing rate of 184 basis points) during the year ended December 31, 2018. 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 fair value of the loaned securities to be separately maintained. The loaned securities’ fair value is monitored on a daily basis. As of September 30, 2019, securities with a fair value of $76.7 million were loaned under this program. As collateral for the loaned securities, the Company receives cash and short-term investments, which is invested in collateralized short-term investments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company leases administrative and marketing office space in approximately 19 cities (excluding the home office building), as well as various office equipment. Most leases have terms ranging from 1 year to 10 years. Leases with an initial term of 12 months or less are not recorded on the consolidated condensed balance sheet. The Company accounts for lease components separately from non-lease components (e.g., common area maintenance). Certain of the Company’s lease agreements include options to renew at its discretion. Management has concluded that the Company is not reasonably certain to elect any of these renewal options. The Company will use the interest rates received on its funding agreement backed notes as the collateralized discount rate when calculating the present value of remaining lease payments when the rate implicit in the lease is unavailable. Additionally, the Company previously leased a building contiguous to its home office. The lease was renewed in December 2013 and was extended to December 2018. At the end of the lease term in December 2018, the Company purchased the building for approximately $75.0 million. The building is recorded in property and equipment on the consolidated condensed balance sheet. 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 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. Advance Trust & Life Escrow Services, LTA, as Securities Intermediary of Life Partners Position Holder Trust v. Protective Life Insurance Company, Case No. 2:18-CV-01290, is a putative class action that was filed on August 13, 2018 in the United States District Court for the Northern District of Alabama. Plaintiff alleges that the Company required policyholders to pay unlawful and excessive cost of insurance charges. Plaintiff seeks to represent all owners of universal life and variable universal life policies issued or administered by the Company or its predecessors that provide that cost of insurance rates are to be determined based on expectations of future mortality experience. The plaintiff seeks class certification, compensatory damages, pre-judgment and post judgment interest, costs, and other unspecified relief. The Company is vigorously defending this matter and cannot predict the outcome of or reasonably estimate the possible loss or range of loss that might result from this litigation. Scottish Re (U.S.), Inc. ("SRUS") was placed in rehabilitation on March 6, 2019 by the State of Delaware. Under the related order, the Insurance Commissioner of the State of Delaware has been appointed the receiver of SRUS and provided with authority to conduct and continue the business of SRUS in the interest of its cedents, creditors, and stockholder. The order was accompanied by an injunction requiring the continued payment of reinsurance premiums to SRUS and temporarily prohibiting cedents, including the Company, from offsetting premiums payable against receivables from SRUS. On June 20, 2019, the Delaware Court of Chancery entered an order approving a Revised Offset Plan, which allows cedents, including the Company, to offset premiums under certain circumstances. As of September 30, 2019, the Company had outstanding claims receivable from SRUS of $18.4 million, and other exposures associated with reinsurance receivables of approximately $96.4 million and statutory reserve credit of approximately $105.7 million. The Company continues to monitor SRUS and the actions of the receiver through discussions with legal counsel and review of publicly available information. However, management does not have sufficient information about the current assets or capital position of SRUS. Additionally, it is unclear how the rehabilitation process will proceed or whether or to what extent the ultimate outcome of the rehabilitation process will be unfavorable to the Company. The Company considered whether the accrual of a loss contingency under FASB ASC Topic 450, Contingencies , was appropriate with respect to amounts receivable from SRUS for ceded claims and reserves as of September 30, 2019. Due to the lack of sufficient information to support an analysis of SRUS's financial condition as of September 30, 2019 and uncertainty regarding whether and to what extent the ultimate outcome of the rehabilitation process will result in an outcome unfavorable to the Company, management concluded that any possible impairment of its reinsurance receivables balance could not be reasonably estimated.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company used its respective estimates for its annual 2019 and 2018 incomes in computing its effective income tax rates for the three and nine months ended September 30, 2019 and 2018. The effective tax rates for the three and nine months ended September 30, 2019 and 2018, were 20.6% and 19.2% and 17.5% and 16.3%, respectively. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: As of September 30, 2019 December 31, 2018 (Dollars In Thousands) Balance, beginning of period $ 7,134 $ 11,353 Additions for tax positions of the current year — — Additions for tax positions of prior years — — Reductions of tax positions of prior years: Changes in judgment — (4,219) Settlements during the period (5,343) — Lapses of applicable statute of limitations — — Balance, end of period $ 1,791 $ 7,134 Included in the end of period balance above, as of September 30, 2019 and December 31, 2018, there were no unrecognized tax benefits 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 $1.8 million and $7.1 million for the period ending September 30, 2019 and the year ending December 31, 2018, 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 the period ending September 30, 2019 and the year ending December 31, 2018 as the parent company maintains responsibility for the interest on unrecognized tax benefits. In April, 2019, the IRS proposed favorable and unfavorable adjustments to the Company’s 2014 through 2016 reported taxable income. The Company agreed to these adjustments. The resulting taxes have been settled, other than interest, and the settlement of interest will not materially impact the Company or its effective tax rate. This agreement with the IRS is the primary cause for the reductions of unrecognized tax benefits shown in the chart above. The Company believes that in the next twelve months, none of the unrecognized tax benefits will be reduced. Statute of limitations for years before 2017 are still open but, in general, the Company is no longer subject to income tax examinations by taxing authorities for tax years that began before 2017. Due to IRS adjustments to the Company's pre-2014 taxable income, the Company has amended 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.

OPERATING SEGMENTS

OPERATING SEGMENTS	9 Months Ended

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 universal life (“UL”), indexed universal life (“IUL”), variable universal life (“VUL”), bank-owned life insurance (“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 marketing 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, however, some recent acquisitions have included ongoing new business activities. Ongoing new product sales written by the Company from these acquisitions are included in the Life Marketing and/or Annuities segment. As a result, 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 guaranteed investment contracts (“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 products are designed to cover the difference between the scheduled 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 deferred policy acquisition costs (“DAC”), value of business acquired (“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. 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. There were no significant intersegment transactions during the three and nine months ended September 30, 2019 and 2018. The following tables present a summary of results and reconciles pre-tax adjusted operating income (loss) to consolidated income before income tax and net income: For The For The 2019 2018 2019 2018 (Dollars In Thousands) Revenues Life Marketing $ 441,108 $ 407,708 $ 1,274,496 $ 1,195,074 Acquisitions 859,524 581,054 2,136,497 1,469,787 Annuities 210,114 110,386 542,736 321,880 Stable Value Products 59,954 59,328 187,118 158,944 Asset Protection 88,696 90,926 266,345 266,747 Corporate and Other 22,597 20,561 90,083 90,686 Total revenues $ 1,681,993 $ 1,269,963 $ 4,497,275 $ 3,503,118 Pre-tax Adjusted Operating Income (Loss) Life Marketing $ (24,669) 3,647 (22,481) $ (18,326) Acquisitions 103,210 93,648 247,932 208,206 Annuities 27,684 36,249 109,886 112,234 Stable Value Products 20,863 27,126 71,208 76,198 Asset Protection 9,637 7,051 26,945 16,991 Corporate and Other (36,563) (41,927) (119,675) (119,474) Pre-tax adjusted operating income 100,162 125,794 313,815 275,829 Realized gains (losses) on investments and derivatives 139,679 (30,624) 288,476 (97,829) Income before income tax 239,841 95,170 602,291 178,000 Income tax expense (49,417) (16,646) (115,355) (28,933) Net income $ 190,424 $ 78,524 $ 486,936 $ 149,067 Pre-tax adjusted operating income $ 100,162 $ 125,794 $ 313,815 $ 275,829 Adjusted operating income tax expense (20,085) (23,077) (54,775) (49,477) After-tax adjusted operating income 80,077 102,717 259,040 226,352 Realized gains (losses) on investments and derivatives 139,679 (30,624) 288,476 (97,829) Income tax (expense) benefit on adjustments (29,332) 6,431 (60,580) 20,544 Net income $ 190,424 $ 78,524 $ 486,936 $ 149,067 Realized investment (losses) gains: Derivative financial instruments $ 42,286 $ (26,710) $ (86,288) $ 37,176 All other investments 88,217 (20,156) 317,254 (157,350) Net impairment losses recognized in earnings (10,818) (14) (14,658) (3,664) Less: related amortization (1) (6,205) (5,859) (37,406) 5,060 Less: VA GLWB economic cost (13,789) (10,397) (34,762) (31,069) Realized gains (losses) on investments and derivatives $ 139,679 $ (30,624) $ 288,476 $ (97,829) (1) Includes amortization of DAC/VOBA and benefits and settlement expenses that are impacted by realized gains (losses).

Accounting Policies [Abstract]
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, PLC’s stock was publicly traded on the New York Stock Exchange. Subsequent to the Merger, 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 consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for the interim periods presented herein. In the opinion of management, the accompanying consolidated condensed financial statements reflect all adjustments (consisting only of normal recurring items) necessary for a fair presentation of the results for the interim periods presented. Operating results for the three and nine months ended September 30, 2019, are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2019. The year-end consolidated condensed financial data included herein was derived from audited financial statements but this report does not include all disclosures required by GAAP. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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.
Reclassifications	During the fourth quarter of 2018, the Company identified certain cash flows that were incorrectly classified in the Company’s historical consolidated statements of cash flows. The Company has determined that these misclassifications were not material to the financial statements for any period. These amounts have been corrected in the comparative consolidated statements of cash flows for the nine months ended September 30, 2019. The nine months ended September 30, 2018 amounts have been revised resulting in an increase in operating cash flows and corresponding decrease in financing cash flows of $88.0 million compared to the amounts previously reported.
Entities Included	Entities Included The consolidated condensed financial statements in this report 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 Pronouncements Recently Adopted and Not Yet Adopted	Accounting Pronouncements Recently Adopted Accounting Standards Update (“ASU” or “Update”) No. 2016-02 - Leases. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of leases. The most significant change relates to the accounting model used by lessees. The Update requires 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 are measured at the present value of the minimum lease payments less any upfront payments or fees. The amendments in the Update became effective for annual and interim periods beginning after December 15, 2018 on a modified retrospective basis. The Company recorded a cumulative effect adjustment as of the date of adoption, January 1, 2019, establishing a right of use asset and lease liability of $18.2 million on its consolidated condensed balance sheet reflected in the property and equipment and other liabilities line items, respectively. 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 previous guidance, under which premiums are amortized to the maturity date of the security. The amendments became effective for annual and interim periods beginning after December 15, 2018. The Company recorded a cumulative effect adjustment as of the adoption date, January 1, 2019, resulting in a $50.8 million reduction to retained earnings, net of income tax. 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 became effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. At adoption, January 1, 2019, this standard did not have an impact on the Company’s operations or financial results. Accounting Pronouncements Not Yet Adopted 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, along with related amendments in ASU No. 2018-19 - Codification Improvements to Topic 326, Financial Instruments-Credit Losses, are effective for annual and interim periods beginning after December 15, 2019 on a modified retrospective basis. The Company has completed its scoping and gap analysis with respect to the implementation of the new standard. Additionally, the Company is in the testing phase with respect to its calculation of the allowance for credit losses for its portfolio of commercial mortgage loans and mortgage loan commitments and reinsurance receivables. A vendor-sourced credit loss model will be used to measure the allowance for the majority of the Company’s commercial mortgage loans and unfunded mortgage loan commitments, and the Company will use an internally-developed calculation to measure the allowance for reinsurance receivables. Testing and review activities which have not yet been completed include final user acceptance testing of the vendor model for commercial mortgage loans, as well as final approval of certain model inputs such as economic forecasts and mean reversion parameters which will materially impact the final allowance. The Company is on track to complete its testing and assumption review in the fourth quarter. In addition to development and testing of the calculation of the allowance for credit losses for these assets, the Company continues to implement new processes and controls with respect to the measurement and recognition of the allowance, along with the additional disclosures required by the Update. The Company expects to record a cumulative effect adjustment which includes an additional allowance for credit losses for commercial mortgage loans and reinsurance receivables. The amount of the cumulative effect adjustment cannot yet be reasonably estimated, as the allowance for credit losses recorded as of January 1, 2020 may be materially impacted by a) model inputs that have not been finalized or b) changes in macroeconomic conditions or other events and circumstances that cannot be reasonably forecasted. ASU No. 2018-12 - Financial Services - Insurance (Topic 944): Targeted Improvements to Accounting for Long-Duration Contracts. The amendments in this Update are designed to make improvements to the existing recognition, measurement, presentation, and disclosure requirements for certain long-duration contracts issued by an insurance company. The new amendments require insurance entities to provide a more current measure of the liability for future policy benefits for traditional and limited-payment contracts by regularly refining the liability for actual past experience and updated future assumptions. This differs from current requirements where assumptions are locked-in at contract issuance for these contract types. In addition, the updated liability will be discounted using an upper-medium grade (low-credit-risk) fixed income instrument yield that reflects the characteristics of the liability which differs from currently used rates based on the invested assets supporting the liability. In addition, the amendments introduce new requirements to assess market-based insurance contract options and guarantees for Market Risk Benefits and measure them at fair value. This Update also requires insurance entities to amortize deferred acquisition costs on a constant-level basis over the expected life of the contract. Finally this Update requires new disclosures including liability rollforwards and information about significant inputs, judgments, assumptions, and methods used in the measurement. The amendments in this Update are currently effective for annual and interim periods beginning after December 15, 2020 with early adoption permitted. However, in October 2019, the Financial Accounting Standards Board (the “FASB”) affirmed their previous decision to delay the effective date of the Update by one year for larger SEC filers and two or three years for others, with early adoption permitted. A final Update is currently being drafted and when issued will extend the implementation deadline for the Company by one year to periods beginning after December 15, 2021. The Company has started its implementation efforts and is currently reviewing its policies, processes, and applicable systems to determine the impact this standard will have on its operations and financial results. While it is not possible to estimate the expected impact of adoption at this time, given the nature and extent of the required changes to a significant portion of the Company’s operations, adoption is expected to have a significant impact on our consolidated financial statements and related disclosures and will require changes to certain of our processes, systems, and controls. ASU No. 2018-15 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40). The amendments in this update require customers in a cloud computing arrangement accounted for as a service contract to capitalize implementation costs incurred in the arrangement . Capitalization should be based on the nature of the costs and the project stage at which the cost was incurred. The amendments in the Update are effective for annual and interim periods beginning after December 15, 2019 on either a retrospective or prospective basis. There will be no impact at the adoption date as the Company will adopt the amendments on a prospective basis.
