Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Basis of Presentation Protective Life Insurance Company (the “Company”), a stock life insurance company, was founded in 1907. The Company is a wholly owned subsidiary of Protective Life Corporation (“PLC”), an insurance holding company. On February 1, 2015, PLC became a wholly owned subsidiary of The Dai-ichi Life Insurance Company, Limited, a kabushiki kaisha organized under the laws of Japan (now known as Dai-ichi Life Holdings, Inc., “Dai-ichi Life”), when DL Investment (Delaware), Inc. a wholly owned subsidiary of Dai-ichi Life, merged with and into PLC. Prior to February 1, 2015, PLC’s stock was publicly traded on the New York Stock Exchange. Subsequent to the Merger date, PLC and the Company remain as SEC registrants within the United States. The Company markets individual life insurance, credit life and disability insurance, guaranteed investment contracts, guaranteed funding agreements, fixed and variable annuities, and extended service contracts throughout the United States. The Company also maintains a separate segment devoted to the acquisition of insurance policies from other companies. PLC is a holding company with subsidiaries that provide financial services through the production, distribution, and administration of insurance and investment products. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for the interim periods presented herein. Such accounting principles differ from statutory reporting practices used by insurance companies in reporting to state regulatory authorities. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements reflect all adjustments (consisting only of normal recurring items) necessary for a fair statement of the results for the interim periods presented. Operating results for the three and six months ended June 30, 2017 , are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2017 . The year-end consolidated condensed financial data included herein was derived from audited financial statements but does not include all disclosures required by GAAP within this report. 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, 2016 . The operating results of companies in the insurance industry have historically been subject to significant fluctuations due to changing competition, economic conditions, interest rates, investment performance, insurance ratings, claims, persistency, and other factors. Entities Included The consolidated 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 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, 2016 . There were no significant changes to the Company's accounting policies during the six months ended June 30, 2017 . Accounting Pronouncements Recently Adopted ASU No. 2017-04-Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This Update simplifies the goodwill impairment test by re-defining the concept of goodwill impairment as the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The Update eliminates “Step 2” of the current goodwill impairment test, which requires entities to determine goodwill impairment by calculating the implied fair value of goodwill by remeasuring to fair value the assets and liabilities of a reporting unit as if that reporting unit had been acquired in a business combination. The Company elected to adopt the amendments in the Update in the first quarter of 2017, and will apply the revised guidance to impairment tests conducted after January 1, 2017. Application of the revised guidance did not impact the Company’s financial position or results of operations and will simplify its annual goodwill impairment test, which is generally conducted in the fourth quarter. For more details regarding the Company’s goodwill assessment process, please refer to Note 9, Goodwill . ASU No. 2015-09 - Financial Services-Insurance (Topic 944): Disclosures about Short-Duration Contracts. The amendments in this Update require additional disclosures for short-duration contracts issued by insurance entities. The additional disclosures focus on the liability for unpaid claims and claim adjustment expenses and include incurred and paid claims development information by accident year in tabular form, along with a reconciliation of this information to the statement of financial position. For accident years included in the development tables, the amendments also require disclosure of the total incurred-but-not-reported liabilities and expected development on reported claims, along with claims frequency information unless impracticable. Finally, the amendments require disclosure of the historical average annual percentage payout of incurred claims. With the exception of the current reporting period, claims development information may be presented as supplementary information. The Update is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. The additional disclosures introduced in this Update have not been provided, as the short-duration lines of business to which they apply are not material to the Company’s financial statements. Accounting Pronouncements Not Yet Adopted ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606). This Update provides for significant revisions to the recognition of revenue from contracts with customers across various industries. Under the new guidance, entities are required to apply a prescribed 5-step process to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The accounting for revenues associated with insurance products is not within the scope of this Update. The Update was originally effective for annual and interim periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU No. 2015-14 - Revenues from Contracts with Customers: Deferral of the Effective Date , to defer the effective date of ASU No. 2014-09 by one year to annual and interim periods beginning after December 15, 2017. The Company will adopt this Update on January 1, 2018 using the modified retrospective approach method. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, may impact several of the Company's non-core lines of business, specifically revenues at the Company's affiliated broker dealers and insurance agency. Additionally, certain non-insurance products sold from the Asset Protection Division, such as fee-for-service arrangements, are expected to be in the scope of the revised guidance. Several application questions remain outstanding, most notably interpretive positions from the AICPA regarding the Update's application to insurance companies and products. Based on the assessment completed to date, the Company does not anticipate material financial impact from the implementation of the revised guidance. ASU No. 2016-01 - Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most notably, the Update requires that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) be measured at fair value with changes in fair value recognized in net income. The Update also introduces a single-step impairment model for equity investments without a readily determinable fair value. Additionally, the Update requires changes in instrument-specific credit risk for fair value option liabilities to be recorded in other comprehensive income. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2017 and will be applied on a modified retrospective basis. The Company expects to complete its review of applicable policies and procedures to ensure compliance with the revised guidance. ASU No. 2016-02 - Leases. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of leases. The most significant change will relate to the accounting model used by lessees. The Update will require all leases with terms greater than 12 months to be recorded on the balance sheet in the form of a lease asset and liability. The lease asset and liability will be measured at the present value of the minimum lease payments less any upfront payments or fees. The Update also requires numerous disclosure changes for which the Company is assessing the impact. The amendments in the Update are effective for annual and interim periods beginning after December 15, 2018 on a modified retrospective basis. The Company has completed an inventory of all leases in the organization and is currently assessing the impact of the Update and updating internal processes to ensure compliance with the revised guidance. ASU No. 2016-13 - Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this Update introduce a new current expected credit loss (“CECL”) model for certain financial assets, including mortgage loans and reinsurance receivables. The new model will not apply to debt securities classified as available-for-sale. For assets within the scope of the new model, an entity will recognize as an allowance against earnings its estimate of the contractual cash flows not expected to be collected on day one of the asset’s acquisition. The allowance may be reversed through earnings if a security recovers in value. This differs from the current impairment model, which requires recognition of credit losses when they have been incurred and recognizes a security’s subsequent recovery in value in other comprehensive income. The Update also makes targeted changes to the current impairment model for available-for-sale debt securities, which comprise the majority of the Company’s invested assets. Similar to the CECL model, credit loss impairments will be recorded in an allowance against earnings that may be reversed for subsequent recoveries in value. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2019 on a modified retrospective basis. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption, and assessing the impact this standard will have on its operations and financial results. ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include: Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2018 using the retrospective method. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption. ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company expects to complete its review of applicable policies and procedures to ensure compliance with the revised guidance. ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the Update provide a specific test by which an entity may determine whether an acquisition involves a set of assets or a business. The amendments in the Update are to be applied prospectively for periods beginning after December 15, 2017. The Company has reviewed the revised requirements, and does not anticipate that the changes will impact its policies or recent conclusions related to its acquisition activities. ASU No. 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this update require entities to disaggregate the current-service-cost component from other components of net benefit cost and present it with other current compensation costs in the income statement. The other components of net benefit cost must be presented outside of income from operations if that subtotal is presented. In addition, the Update requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. As provided for in the ASU, the Company expects to apply the provisions of the statement retrospectively for components of net periodic pension costs and prospectively for capitalization of the service costs component of net periodic costs and net periodic postretirement benefits. The Update will not impact the Company’s financial position or results of operations. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption. ASU No. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine whether early adoption of the revised guidance is practicable .

MONY CLOSED BLOCK OF BUSINESS

MONY CLOSED BLOCK OF BUSINESS	6 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. 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 June 30, 2017 , and December 31, 2016 is as follows: As of June 30, 2017 December 31, 2016 (Dollars In Thousands) Closed block liabilities Future policy benefits, policyholders’ account balances and other policyholder liabilities $ 5,837,388 $ 5,896,355 Policyholder dividend obligation 123,449 31,932 Other liabilities 18,662 40,007 Total closed block liabilities 5,979,499 5,968,294 Closed block assets Fixed maturities, available-for-sale, at fair value $ 4,568,414 $ 4,440,105 Mortgage loans on real estate 153,106 201,088 Policy loans 709,618 712,959 Cash 52,863 108,270 Other assets 139,948 135,794 Total closed block assets 5,623,949 5,598,216 Excess of reported closed block liabilities over closed block assets 355,550 370,078 Portion of above representing accumulated other comprehensive income: Net unrealized investment gains (losses) net of policyholder dividend obligation: $(80,032) and $(197,450); and net of income tax: $28,011 and $69,107 — — Future earnings to be recognized from closed block assets and closed block liabilities $ 355,550 $ 370,078 Reconciliation of the policyholder dividend obligation is as follows: For The 2017 2016 (Dollars In Thousands) Policyholder dividend obligation, beginning of period $ 31,932 $ — Applicable to net revenue (losses) (25,901 ) (28,921 ) Change in net unrealized investment gains (losses) allocated to the policyholder dividend obligation 117,418 261,343 Policyholder dividend obligation, end of period $ 123,449 $ 232,422 Closed Block revenues and expenses were as follows: For The For The 2017 2016 2017 2016 (Dollars In Thousands) Revenues Premiums and other income $ 44,898 $ 47,320 $ 87,734 $ 91,239 Net investment income 51,343 52,008 102,701 102,875 Net investment gains 43 450 106 637 Total revenues 96,284 99,778 190,541 194,751 Benefits and other deductions Benefits and settlement expenses 87,490 92,029 167,598 172,084 Other operating expenses 428 653 592 1,677 Total benefits and other deductions 87,918 92,682 168,190 173,761 Net revenues before income taxes 8,366 7,096 22,351 20,990 Income tax expense 2,928 2,484 7,823 7,346 Net revenues $ 5,438 $ 4,612 $ 14,528 $ 13,644

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 $11.3 million as of June 30, 2017 . This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the Federal Family Education Loan Program (“FFELP”). At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary. The other government-related securities had gross unrealized losses greater than twelve months of $7.7 million as of June 30, 2017 . These declines were related to changes in interest rates. The states, municipalities, and political subdivisions category had gross unrealized losses greater than twelve months of $36.3 million as of June 30, 2017 . These declines were related to changes in interest rates. The corporate securities category had gross unrealized losses greater than twelve months of $636.9 million as of June 30, 2017 . The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information As of June 30, 2017 , the Company had a total of 1,846 positions that were in an unrealized loss position, but the Company does not consider these unrealized loss positions to be other-than-temporary. This is based on the aggregate factors discussed previously and because the Company has the ability and intent to hold these investments until the fair values recover, and the Company does not intend to sell or expect to be required to sell the securities before recovering the Company’s amortized cost of the securities. The following table includes the gross unrealized losses and fair value of the Company’s investments that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of December 31, 2016 : Less Than 12 Months 12 Months or More Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss (Dollars In Thousands) Residential mortgage-backed securities $ 1,051,694 $ (21,178 ) $ 170,826 $ (4,117 ) $ 1,222,520 $ (25,295 ) Commercial mortgage-backed securities 1,426,252 (36,589 ) 100,475 (4,013 ) 1,526,727 (40,602 ) Other asset-backed securities 323,706 (9,291 ) 176,792 (11,407 ) 500,498 (20,698 ) U.S. government-related securities 1,237,942 (40,454 ) 3 (1 ) 1,237,945 (40,455 ) Other government-related securities 98,412 (2,907 ) 79,393 (11,890 ) 177,805 (14,797 ) States, municipalities, and political subdivisions 1,062,368 (63,809 ) 548,254 (41,749 ) 1,610,622 (105,558 ) Corporate securities 12,490,517 (467,463 ) 9,791,313 (1,114,635 ) 22,281,830 (1,582,098 ) Preferred stock 66,781 (6,642 ) 19,062 (1,877 ) 85,843 (8,519 ) Equities 411,845 (15,273 ) 69,497 (6,412 ) 481,342 (21,685 ) $ 18,169,517 $ (663,606 ) $ 10,955,615 $ (1,196,101 ) $ 29,125,132 $ (1,859,707 ) RMBS and CMBS had gross unrealized losses greater than twelve months of $4.1 million and $4.0 million , respectively, as of December 31, 2016 . 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 $11.4 million as of December 31, 2016 . This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the FFELP. At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary. The other government-related securities had gross unrealized losses greater than twelve months of $11.9 million as of December 31, 2016. These declines were related to changes in interest rates. The states, municipalities, and political subdivisions category had gross unrealized losses greater than twelve months of $41.7 million as of December 31, 2016 . These declines were related to changes in interest rates. The corporate securities category had gross unrealized losses greater than twelve months of $1.1 billion as of December 31, 2016 . The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information As of June 30, 2017 , the Company had securities in its available-for-sale portfolio which were rated below investment grade of $1.9 billion and had an amortized cost of $1.9 billion . In addition, included in the Company’s trading portfolio, the Company held $240.2 million of securities which were rated below investment grade. Approximately $341.5 million of the available-for-sale and trading securities tha t were below investment grade were not publicly traded. The change in unrealized gains (losses), net of income tax, on fixed matur ity and equity securities, classified as available-for-sale is summarized as follows: For The For The 2017 2016 2017 2016 (Dollars In Thousands) Fixed maturities $ 474,906 $ 845,933 $ 698,255 $ 1,476,650 Equity securities 6,822 9,509 21,390 9,439 The amortized cost and fair value of the Company’s investments classified as held-to-maturity as of June 30, 2017 and December 31, 2016 , are as follows: As of June 30, 2017 Amortized Gross Holding Gross Holding Fair Total OTTI (Dollars In Thousands) Fixed maturities: Securities issued by affiliates: Red Mountain LLC $ 682,077 $ — $ (22,575 ) $ 659,502 $ — Steel City LLC 2,065,000 80,605 — 2,145,605 — $ 2,747,077 $ 80,605 $ (22,575 ) $ 2,805,107 $ — As of December 31, 2016 Amortized Gross Gross Fair Total OTTI (Dollars In Thousands) Fixed maturities: Securities issued by affiliates: Red Mountain LLC $ 654,177 $ — $ (67,222 ) $ 586,955 $ — Steel City LLC 2,116,000 30,385 — 2,146,385 — $ 2,770,177 $ 30,385 $ (67,222 ) $ 2,733,340 $ — During the three and six months ended June 30, 2017 and 2016 , the Company recorded no other-than-temporary impairments on held-to-maturity securities. The Company’s held-to-maturity securi ties had $80.6 million of gross unrecognized holding gains and $22.6 million of gross unrecognized holding losses by maturity as of June 30, 2017 . The Company does not consider these unrecognized holding losses to be other-than-temporary based on certain positive factors associated with the securities which include credit ratings of the guarantor, financial health of the issuer and guarantor, continued access of the issuer to capital markets and other pertinent information. These held-to-maturity securities are issued by affiliates of the Company which are considered variable interest entities ("VIE's"). The Company is not the primary beneficiary of these entities and thus the securities are not eliminated in consolidation. These securities are collateralized by non-recourse funding obligations issued by captive insurance companies that are affiliates of the Company. The Company’s held-to-maturity securities had $30.4 million of gross unrecognized holding gains and $67.2 million of gross unrecognized holding losses by maturity as of December 31, 2016. 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 Entities The Company holds certain investments in entities in which its ownership interests could possibly be considered variable interests under Topic 810 of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC” or “Codification”) (excluding debt and equity securities held as trading, available for sale, or held to maturity). The Company reviews the characteristics of each of these applicable entities and compares those characteristics to applicable criteria to determine whether the entity is a 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 June 30, 2017 and December 31, 2016 , that was determined to be a VIE. The activity most significant to Red Mountain is the issuance of a note in connection with a financing transaction involving Golden Gate V Vermont Captive Insurance Company (“Golden Gate V”) and the Company in which Golden Gate V issued non-recourse funding obligations to Red Mountain and Red Mountain issued the note to Golden Gate V. Credit enhancement on the Red Mountain Note is provided by an unrelated third party. The Company had the power, via its 100% ownership through an affiliate, to direct the activities of the VIE, but did not have the obligation to absorb losses related to the primary risks or sources of variability to the VIE. The variability of loss would be borne primarily by the third party in its function as provider of credit enhancement on the Red Mountain Note. Accordingly, it was determined that the Company is not the primary beneficiary of the VIE. The Company’s risk of loss related to the VIE is limited to its investment of $10,000 . Additionally, the Company has guaranteed Red Mountain’s payment obligation for the credit enhancement fee to the unrelated third party provider. As of June 30, 2017 , no payments have been made or required related to this guarantee.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS The Company determined the fair value of its financial instruments based on the fair value hierarchy established in FASB guidance referenced in the Fair Value Measurements and Disclosures Topic which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company has adopted the provisions from the FASB guidance that is referenced in the Fair Value Measurements and Disclosures Topic for non-financial assets and liabilities (such as property and equipment, goodwill, and other intangible assets) that are required to be measured at fair value on a periodic basis. The effect on the Company’s periodic fair value measurements for non-financial assets and liabilities was not material. The Company has categorized its financial instruments, based on the priority of the inputs to the valuation technique, into a three level hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the consolidated balance sheets are categorized as follows: • Level 1: Unadjusted quoted prices for identical assets or liabilities in an active market. • Level 2: Quoted prices in markets that are not active or significant inputs that are observable either directly or indirectly. Level 2 inputs include the following: a. Quoted prices for similar assets or liabilities in active markets b. Quoted prices for identical or similar assets or liabilities in non-active markets c. Inputs other than quoted market prices that are observable d. Inputs that are derived principally from or corroborated by observable market data through correlation or other means. • Level 3: Prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. They reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. The following table presents the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis as of June 30, 2017 : Level 1 Level 2 Level 3 Total (Dollars In Thousands) Assets: Fixed maturity securities - available-for-sale Residential mortgage-backed securities $ — $ 1,980,453 $ 11,862 $ 1,992,315 Commercial mortgage-backed securities — 1,802,778 — 1,802,778 Other asset-backed securities — 629,040 552,963 1,182,003 U.S. government-related securities 1,010,562 285,546 — 1,296,108 State, municipalities, and political subdivisions — 1,689,321 — 1,689,321 Other government-related securities — 249,458 — 249,458 Corporate securities — 27,514,221 662,654 28,176,875 Preferred stock 74,134 18,934 — 93,068 Total fixed maturity securities - available-for-sale 1,084,696 34,169,751 1,227,479 36,481,926 Fixed maturity securities - trading Residential mortgage-backed securities — 264,109 — 264,109 Commercial mortgage-backed securities — 152,522 — 152,522 Other asset-backed securities — 110,852 54,923 165,775 U.S. government-related securities 21,609 4,492 — 26,101 State, municipalities, and political subdivisions — 323,720 — 323,720 Other government-related securities — 63,763 — 63,763 Corporate securities — 1,688,476 5,520 1,693,996 Preferred stock 3,113 — — 3,113 Total fixed maturity securities - trading 24,722 2,607,934 60,443 2,693,099 Total fixed maturity securities 1,109,418 36,777,685 1,287,922 39,175,025 Equity securities 684,455 — 65,686 750,141 Other long-term investments (1) 68,323 361,195 93,245 522,763 Short-term investments 333,255 28,793 — 362,048 Total investments 2,195,451 37,167,673 1,446,853 40,809,977 Cash 244,197 — — 244,197 Assets related to separate accounts Variable annuity 13,616,259 — — 13,616,259 Variable universal life 959,638 — — 959,638 Total assets measured at fair value on a recurring basis $ 17,015,545 $ 37,167,673 $ 1,446,853 $ 55,630,071 Liabilities: Annuity account balances (2) $ — $ — $ 86,094 $ 86,094 Other liabilities (1) 6,586 266,193 532,763 805,542 Total liabilities measured at fair value on a recurring basis $ 6,586 $ 266,193 $ 618,857 $ 891,636 (1) Includes certain freestanding and embedded derivatives.

(2) Represents liabilities related to fixed indexed annuities. Determination of fair values The valuation methodologies used to determine the fair values of assets and liabilities reflect market participant assumptions and are based on the application of the fair value hierarchy that prioritizes observable market inputs over unobservable inputs. The Company determines the fair values of certain financial assets and financial liabilities based on quoted market prices, where available. The Company also determines certain fair values based on future cash flows discounted at the appropriate current market rate. Fair values reflect adjustments for counterparty credit quality, the Company’s credit standing, liquidity, and where appropriate, risk margins on unobservable parameters. The following is a discussion of the methodologies used to determine fair values for the financial instruments as listed in the above table. The fair value of fixed maturity, short-term, and equity securities is determined by management after considering one of three primary sources of information: third party pricing services, non-binding independent broker quotations, or pricing matrices. Security pricing is applied using a “waterfall” approach whereby publicly available prices are first sought from third party pricing services, the remaining unpriced securities are submitted to independent brokers for non-binding prices, or lastly, securities are priced using a pricing matrix. Typical inputs used by these three pricing methods include, but are not limited to: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. Third party pricing services price approxi mately 91% of the Company’s available-for-sale and trading fixed maturity securities. Based on the typical trading volumes and the lack of quoted market prices for available-for-sale and trading fixed maturities, third party pricing services derive the majority of security prices from observable market inputs such as recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information outlined above. If there are no recent reported trades, the third party pricing services and brokers may use matrix or model processes to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Certain securities are priced via independent non-binding broker quotations, which are considered to have no significant unobservable inputs. When using non-binding independent broker quotations, the Company obtains one quote per security, typically from the broker from which we purchased the security. A pricing matrix is used to price securities for which the Company is unable to obtain or effectively rely on either a price from a third party pricing service or an independent broker quotation. The pricing matrix used by the Company begins with current spread levels to determine the market price for the security. The credit spreads, assigned by brokers, incorporate the issuer’s credit rating, liquidity discounts, weighted- average of contracted cash flows, risk premium, if warranted, due to the issuer’s industry, and the security’s time to maturity. The Company uses credit ratings provided by nationally recognized rating agencies. For securities that are priced via non-binding independent broker quotations, the Company assesses whether prices received from independent brokers represent a reasonable estimate of fair value through an analysis using internal and external cash flow models developed based on spreads and, when available, market indices. The Company uses a market-based cash flow analysis to validate the reasonableness of prices received from independent brokers. These analytics, which are updated daily, incorporate various metrics (yield curves, credit spreads, prepayment rates, etc.) to determine the valuation of such holdings. As a result of this analysis, if the Company determines there is a more appropriate fair value based upon the analytics, the price received from the independent broker is adjusted accordingly. The Company did not adjust any quotes or prices received from brokers during the six months ended June 30, 2017 . 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 June 30, 2017 , the Company held $4.9 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 June 30, 2017 , the Company h eld $619.7 million of Level 3 ABS, which included $564.8 million of other asset-backed securities classified as available-for-sale and $54.9 million of other a sset-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 three measurements due to the nature of the transaction. Corporate Securities, U.S. Government-Related Securities, States, Municipals, and Political Subdivisions, and Other Government Related Securities As of June 30, 2017 , the Company classified approximately $31.8 billion of corporate securities, U.S. government-related securities, states, municipals, and political subdivisions, and other government-related securities as Level 2. The fair value of the Level 2 securities is predominantly priced by broker quotes and a third party pricing service. The Company has reviewed the valuation techniques of the brokers and third party pricing service and has determined that such techniques used Level 2 market observable inputs. The following characteristics of the securities are considered to be the primary relevant inputs to the valuation: 1) weighted- average coupon rate, 2) weighted-average years to maturity, 3) seniority, and 4) credit ratings. The Company reviews the methodologies and valuation techniques (including the ability to observe inputs) in assessing the information received from external pricing services and in consideration of the fair value presentation. The brokers and third party pricing service utilize valuation models that consist of a hybrid income and market approach to valuation. The pricing models utilize the following inputs: 1) principal and interest payments, 2) treasury yield curve, 3) credit spreads from new issue and secondary trading markets, 4) dealer quotes with adjustments for issues with early redemption features, 5) liquidity premiums present on private placements, and 6) discount margins from dealers in the new issue market. As of June 30, 2017 , the Company classified approximately $668.2 million of securities as Level 3 valuations. Level 3 securities primarily represent investments in illiquid bonds for which no price is readily available. To determine a price, the Company uses a discounted cash flow model with both observable and unobservable inputs. These inputs are entered into an industry standard pricing model to determine the final price of the security. These inputs include: 1) principal and interest payments, 2) coupon rate, 3) sector and issuer level spread over treasury, 4) underlying collateral, 5) credit ratings, 6) maturity, 7) embedded options, 8) recent new issuance, 9) comparative bond analysis, and 10) an illiquidity premium. Equities As of June 30, 2017 , the Company held approximately $65.7 million of equity securities classified as Level 2 and Level 3. Of this total, $65.6 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 6, 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 June 30, 2017 , 82.0% of deriva tives 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 were embedded derivatives and include at least one significant non-observable input. A derivative instrument containing Level 1 and Level 2 inputs will be classified as a Level 3 financial instrument in its entirety if it has at least one significant Level 3 input. The Company utilizes derivative instruments to manage the risk associated with certain assets and liabilities. However, the derivative instruments may not be classified within the same fair value hierarchy level as the associated assets and liabilities. Therefore, the changes in fair value on derivatives reported in Level 3 may not reflect the offsetting impact of the changes in fair value of the associated assets and liabilities. The embedded derivatives are carried at fair value in “other long-term investments” and “other liabilities” on the Company’s consolidated condensed balance sheet. The changes in fair value are recorded in earnings as “Realized investment gains (losses)-Derivative financial instruments”. Refer to Note 6, Derivative Financial Instruments for more information related to each embedded derivatives gains and losses . The fair value of the GLWB embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using multiple risk neutral stochastic equity scenarios and policyholder behavior assumptions. The risk neutral scenarios are generated using the current swap curve and projected equity volatilities and correlations. The projected equity volatilities are based on a blend of historical volatility and near- term equity market implied volatilities. The equity correlations are based on historical price observations. For policyholder behavior assumptions, expected lapse and utilization assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the Ruark 2015 ALB table with attained age factors varying from 91.1% - 106.6% . The p resent value of the cash flows is determined using the discount rate curve, which is based upon LIBOR plus a credit spread (to represent the Company’s non-performance risk). As a result of using significant unobservable inputs, the GLWB embedded derivative is categorized as Level 3. Policyholder assumptions are reviewed on an annual basis. The balance of the FIA embedded derivative is impacted by policyholder cash flows associated with the FIA product that are allocated to the embedded derivative in addition to changes in the fair value of the embedded derivative during the reporting period. The fair value of the FIA embedded derivative is derived through the income met hod of valuation using a valuation model that projects future cash flows using current index values and volatility, the hedge budget used to price the product, and policyholder assumptions (both elective and non-elective). For policyholder behavior assumptions, expected lapse and withdrawal assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the 1994 Variable Annuity MGDB mortality table modified with company experience, with attained age factors varying from 46% - 113% . The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR up to one year and constant maturity treasury rates plus a credit spread (to represent the Company’s non-performance risk) thereafter. Policyholder 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 modified with company experience, with attained age factors varying from 38% - 153% . 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 are designated as “trading securities”; therefore changes in their fair value are als o reported in earnings. As of June 30, 2017 , the fair value of the embedded derivative is based upon the relationship between the statutory policy liabilities (net of policy loans) of $2.4 billion and the statutory unrealized gain (loss) of the securities of $207.6 million . As a result, changes in the fair value of the embedded derivatives are largely offset by the changes in fair value of the related inv estments 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 June 30, 2017 was $31.5 million and is included in Other long-term investments. For information regarding realized gains on these derivatives please refer to Note 6, Derivative Financial Instruments . The Interest Support Agreement provides that PLC will make payments to Golden Gate II if actual investment income on certain of Golden Gate II’s asset portfolios falls below a calculated investment income amount as defined in the Interest Support Agreement. The calculated investment income amount is a level of investment income deemed to be sufficient to support certain of Golden Gate II’s obligations under a reinsurance agreement with the Company, dated July 1, 2007. The derivative is valued using an internal valuation model that assumes a conservative projection of investment income under an adverse interest rate scenario and the probability that the expectation falls below the calculated investment income amount. This derivative had a fair value of $25.2 million as of June 30, 2017 . As of June 30, 2017 , no payments have been triggered under this agreement, however, certain interest support agreement obligations to Golden Gate II of approximately $2.8 million have been collateralized by PLC. Re-evaluation and, if necessary, adjustments of any support agreement collateralization amounts occur annually during the first quarter pursuant to the terms of the support agreement. As of June 30, 2017 , no payments have been triggered under this agreement. The YRT premium support agreements provide that PLC will make payments to Golden Gate and Golden Gate II in the event that YRT premium rates increase. The derivatives are valued using an internal valuation model. The valuation model is a probability weighted discounted cash flow model. The value is primarily a function of the likelihood and severity of future YRT premium increases. The fair value of these derivatives as of June 30, 2017 was $2.1 million . As of June 30, 2017 , no payments have been made under these agreements. The portfolio maintenance agreements provide that PLC will make payments to Golden Gate, Golden Gate V, and WCL in the event of other-than-temporary impairments on investments that exceed defined thresholds. The derivatives are valued using an internal discounted cash flow model. The significant unobservable inputs are the projected probability and severity of credit losses used to project future cash flows on the investment portfolios. The fair value of the portfolio maintenance agreements as of June 30, 2017 , was $4.2 million . As of June 30, 2017 , no payments have been made under these agreements. The Funds Withheld derivative results from a reinsurance agreement with Shades Creek where the economic performance of certain hedging instruments held by the Company is ceded to Shades Creek. The value of the Funds Withheld derivative is directly tied to the value of the hedging instruments held in the funds withheld account. The hedging instruments predominantly consist of derivative instruments the fair values of which are classified as a Level 2 measurement; as such, the fair value of the Funds Withheld derivative has been classified as a Level 2 measurement. The fair value of the Funds Withheld derivative as of June 30, 2017 , was a liability of $69.8 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 June 30, 2017 is $86.1 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 Valuation Technique Unobservable Input Range (Weighted Average) (Dollars In Thousands) Assets: Other asset-backed securities $ 552,816 Liquidation Liquidation value $90 - $97 ($95.05) Discounted cash flow Liquidity premium 0.51% - 1.30% (0.94%) Paydown rate 10.82% - 12.15% (11.28%) Corporate securities 634,340 Discounted cash flow Spread over treasury 0.74% - 4.75% (1.72%) Liabilities: (1) Embedded derivatives - GLWB (2) $ 20,824 Actuarial cash flow model Mortality 91.1% to 106.6% of Lapse 0.3% - 15%, depending on Utilization 99%. 10% of policies have a one-time over-utilization of 400% Nonperformance risk 0.10% - 0.86% Embedded derivative - FIA 191,226 Actuarial cash flow model Expenses $126 per policy Asset Earned Rate 4.08% - 4.66% Withdrawal rate 1% prior to age 70, 100% of the RMD for ages 70+ Mortality 1994 MGDB table with company experience Lapse 2.0% - 40%, depending on duration/surrender charge period Nonperformance risk 0.10% - 0.86% Embedded derivative - IUL 62,747 Actuarial cash flow model Mortality 38% - 15.3% of 2015 VBT Primary Tables Lapse 0.5% - 10.0%, depending on duration/distribution channel and smoking class Nonperformance risk 0.10% - 0.86% (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 June 30, 2017 , but the valuation techni ques and inputs used by some brokers in pricing certain financial instruments are not shared with the Company. This resulted in $89.0 million of financial instruments being classified as Level 3 as of June 30, 2017 . Of the $89.0 million , $55.1 million are other asset-backed securities and $33.8 million are corporate securities. In certain cases the Company has determined that book value materially approximates fair value. As of June 30, 2017 , the Company held $77.5 million of financial instruments where book value approximates fair value which were predominantly FHLB stock. The following table presents the valuation method for material financial instruments included in Level 3, as well as the unobservable inputs used in the valuation of those financial instruments: Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars In Thousands) Assets: Other asset-backed securities $ 553,308 Liquidation Liquidation value $88 - $97.25 ($95.04) Corporate securities 638,279 Discounted cash flow Spread over treasury 0.31% - 4.50% (2.04%) Liabilities: (1) Embedded derivatives - GLWB (2) $ 7,031 Actuarial cash flow model Mortality 91.1% to 106.6% of Lapse 0.3% - 15%, depending on product/duration/funded status of guarantee Utilization 99%. 10% of policies have a one-time over-utilization of 400% Nonperformance risk 0.18% - 1.09% Embedded derivative - FIA 147,368 Actuarial cash flow model Expenses $126 per po

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Types of Derivative Instruments and Derivative Strategies The Company utilizes a risk management strategy that incorporates the use of derivative financial instruments to reduce exposure to certain risks, including but not limited to, interest rate risk, currency exchange risk, volatility risk, and equity market risk. These strategies are developed through the Company’s analysis of data from financial simulation models and other internal and industry sources and are then incorporated into the Company’s risk management program. Derivative instruments expose the Company to credit and market risk and could result in material changes from period to period. The Company attempts to minimize its credit risk by entering into transactions with highly rated counterparties. The Company manages the market risk by establishing and monitoring limits as to the types and degrees of risk that may be undertaken. The Company monitors its use of derivatives in connection with its overall asset/liability management programs and risk management strategies. In addition, all derivative programs are monitored by our risk management department. Derivatives Related to Interest Rate Risk Management Derivative instruments that are used as part of the Company’s interest rate risk management strategy include interest rate swaps, interest rate futures, interest rate caps, and interest rate swaptions. Derivatives Related to Foreign Currency Exchange Risk Management Derivative instruments that are used as part of the Company's foreign currency exchange risk management strategy include foreign currency swaps, foreign currency futures, foreign equity futures, and foreign equity options. Derivatives Related to Risk Mitigation of Certain Annuity Contracts The Company may use the following types of derivative contracts to mitigate its exposure to certain guaranteed benefits related to VA contracts and fixed indexed annuities: • Foreign Currency Futures • Variance Swaps • Interest Rate Futures • Equity Options • Equity Futures • Credit Derivatives • Interest Rate Swaps • Interest Rate Swaptions • Volatility Futures • Volatility Options • Funds Withheld Agreement • Total Return Swaps Other Derivatives The Company and certain of its subsidiaries have derivatives with PLC. These derivatives consist of an interest support agreement, YRT premium support agreements, and portfolio maintenance agreements with PLC. The Company has a funds withheld account that consists of various derivative instruments held by us that is used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument. Accounting for Derivative Instruments The Company records its derivative financial instruments in the consolidated balance sheet in “other long-term investments” and “other liabilities” in accordance with GAAP, which requires that all derivative instruments be recognized in the balance sheet at fair value. The change in the fair value of derivative financial instruments is reported either in the statement of income or in other comprehensive income (loss), depending upon whether it qualified for and also has been properly identified as being part of a hedging relationship, and also on the type of hedging relationship that exists. For a derivative financial instrument to be accounted for as an accounting hedge, it must be identified and documented as such on the date of designation. For cash flow hedges, the effective portion of their realized gain or loss is reported as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain attributable to the hedged risk of the hedged item is recognized in current earnings. Effectiveness of the Company’s hedge relationships is assessed on a quarterly basis. The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship through earnings in the period of change. Changes in the fair value of derivatives that are recognized in current earnings are reported in “Realized investment gains (losses)-Derivative financial instruments.” Derivative Instruments Designated and Qualifying as Hedging Instruments Cash-Flow Hedges • To hedge a fixed rate note denominated in a foreign currency, the Company entered into a fixed-to-fixed foreign currency swap in order to hedge the foreign currency exchange risk associated with the note. The cash flows received on the swap are identical to the cash flow paid on the note. Derivative Instruments Not Designated and Not Qualifying as Hedging Instruments The Company uses various other derivative instruments for risk management purposes that do not qualify for hedge accounting treatment. Changes in the fair value of these derivatives are recognized in earnings during the period of change. Derivatives Related to Variable Annuity Contracts • The Company uses equity futures, equity options, total return swaps, interest rate futures, interest rate 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 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, two YRT premium support agreements, and three portfolio maintenance agreements with PLC. The Company entered into three separate portfolio maintenance agreements, two in October 2012 and one in January 2016. • 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 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.

MORTGAGE LOANS
MORTGAGE LOANS	MORTGAGE LOANS Mortgage Loans The Company invests a portion of its investment portfolio in commercial mortgage loans. As of June 30, 2017 , the Company’s mortgage loan holdings were appr oximately $6.5 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 accretion of 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 12 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 June 30, 2017 , assuming the loans are called at their next call dates, approximately $60.9 million of principal would become due for the remainder of 2017 , $1,010.2 million in 2018 through 2022 , $125.7 million in 2023 through 2027 , and $10.0 million thereafter. The Company offers a type of commercial mortgage loan under which the Company will permit a loan-to-value ratio of up to 85% in exchange for a participating interest in the cash flows from the underlying real estate. As of June 30, 2017 , and December 31, 2016 , approxima tely $669.8 million and $595.2 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 six months ended June 30, 2017 and 2016 , the Company recognized $4.7 million , $11.5 million , $5.7 million , and $12.5 million , respectively, of participating mortgage loan income. As of June 30, 2017 , approximately $3.5 million of invested assets consisted of nonperforming mortgage loans, restructured mortgage loans, or mortgage loans that were foreclosed and were converted to real estate properties. The Company does not expect these investments to adversely affect its liquidity or ability to maintain proper matching of assets and liabilities. During the six months ended June 30, 2017, the Company recognized a troubled debt restructuring as a result of the Company granting a concession to a borrower which included loans terms unavailable from other lenders. This concession was the result of agreements between the creditor and the debtor. The Company did not identify any loans whose principal was permanently impaired during the six months ended June 30, 2017. The Company’s mortgage loan portfolio consists of two categories of loans: 1) those not subject to a pooling and servicing agreement and 2) those subject to a contractual pooling and servicing agreement. As of June 30, 2017 , $3.5 million of mortgage loans not subject to a pooling and servicing agreement were nonperforming mortgage loans, restructured, or mortgage loans that were foreclosed and were converted to real estate properties. The Company did no t foreclose on any nonperforming loans not subject to a pooling and servicing agreement during the six months ended June 30, 2017 . As of June 30, 2017 , none of the loans subject to a pooling and servicing agreement were nonperforming or restructured. The Company did no t foreclose on any nonperforming loans subject to a pooling and servicing agreement during the six months ended June 30, 2017 . As of June 30, 2017 , and December 31, 2016 , the Company had an allowance for mortgage loan credit losses of $5.9 million and $0.7 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. For The Six Months Ended June 30, 2017 (Dollars In Thousands) Beginning balance, December 31, 2016 $ 724 Charge offs — Recoveries (724 ) Provision 5,915 Ending balance, June 30, 2017 $ 5,915 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. For loans subject to a pooling and servicing agreement, there are certain additional restrictions and/or requirements related to workout proceedings, and as such, these loans may have different attributes and/or circumstances affecting the status of delinquency or categorization of those in nonperforming status. An analysis of the delinquent loans is shown in the following chart.

Due to the collateralized nature of the loans, any assessment of impairment and ultimate loss given a default on the loans is based upon a consideration of the estimated fair value of the real estate. The Company limits accrued interest income on impaired loans to 90 days of interest. Once accrued interest on the impaired loan is received, interest income is recognized on a cash basis.

GOODWILL

GOODWILL	6 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL	GOODWILL The balance of goodwill for the Company as of June 30, 2017 was $793.5 million . There has been no change to goodwill during the six months ended June 30, 2017 . Accounting for goodwill requires an estimate of the future profitability of the associated lines of business to assess the recoverability of the capitalized acquisition goodwill. The Company evaluates the carrying value of goodwill at the segment (or reporting unit) level at least annually and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Such circumstances could include, but are not limited to: 1) a significant adverse change in legal factors or in business climate, 2) unanticipated competition, or 3) an adverse action or assessment by a regulator. When evaluating whether goodwill is impaired, the Company first determines through qualitative analysis whether relevant events and circumstances indicate that it is more likely than not that segment goodwill balances are impaired as of the testing date. If it is determined that it is more likely than not that impairment exists, the Company compares its estimate of the fair value of the reporting unit to which the goodwill is assigned to the reporting unit’s carrying amount, including goodwill. The Company utilizes a fair value measurement (which includes a discounted cash flows analysis) to assess the carrying value of the reporting units in consideration of the recoverability of the goodwill balance assigned to each reporting unit as of the measurement date. The Company’s material goodwill balances are attributable to certain of its operating segments (which are each considered to be reporting units). The cash flows used to determine the fair value of the Company’s reporting units are dependent on a number of significant assumptions. The Company’s estimates, which consider a market participant view of fair value, are subject to change given the inherent uncertainty in predicting future results and cash flows, which are impacted by such things as policyholder behavior, competitor pricing, capital limitations, new product introductions, and specific industry and market conditions. The balance recognized as goodwill is not amortized, but is reviewed for impairment on an annual basis, or more frequently as events or circumstances may warrant, including those circumstances which would more likely than not reduce the fair value of the Company’s reporting units below its carrying amount. During the fourth quarter of 2016 , the Company performed its annual evaluation of goodwill based on information as of October 1, 2016 , and determined that no adjustment to impair goodwill was necessary. During the six months ended June 30, 2017 , the Company did not identify any events or circumstances which would indicate that the fair value of its operating segments would have declined below their book value, either individually or in the aggregate.

Debt Disclosure [Abstract]
DEBT AND OTHER OBLIGATIONS	DEBT AND OTHER OBLIGATIONS The Company has the ability to borrow on an unsecured basis under a Credit Facility 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 $1.25 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 Federal Funds rate , or (z) the one-month LIBOR plus 1.00% 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 initial facility fee rate was 0.15% on February 2, 2015, and was adjusted to 0.125% upon PLC’s subsequent ratings upgrade on February 2, 2015. 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 February 2, 2020. The Company is not aware of any non-compliance with the financial debt covenants of the Credit Facility as of June 30, 2017 .

(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 provided for net settlement in the event of default or on termination of the agreements. As of June 30, 2017 , the fair value of securities pledged under the repurchase program was $429.8 million , and the repurchase obligation of $413.6 million was included in the Company’s consolidated condensed balance sheets (at an average borrowing rate of 124 basis points). During the six months ended June 30, 2017 , the maximum balance outstanding at any one point in time related to these programs was $981.3 million . The average daily balance was $607.7 million (at an average borrowing rate of 78 basis points) during the six months ended June 30, 2017 . As of December 31, 2016 , the fair value of securities pledged under the repurchase program wa s $861.7 million , and the repurchase obligation of $797.7 million w as included in the Company's consolidated condensed balance sheets (at an average borrowing rate of 65 basis points). During 2016 , the maximum balance outstanding at any one point in time related to these programs w as $1,065.8 million . The average daily balance was $505.4 million (at an average borrowing rate of 44 basis points) during the year ended December 31, 2016 . Securities Lending The Company participates in securities lending, primarily as an investment yield enhancement, whereby securities that are held as investments are loaned out to third parties for short periods of time. The Company requires initial collateral of 102% of the market value of the loaned securities to be separately maintained. The loaned securities’ market value is monitored on a daily basis. As of June 30, 2017, securities with a market value of $25.6 million were loaned under this program. As collateral for the loaned securities, the Company receives short-term investments, which are recorded in “short-term investments” with a corresponding liability recorded in “secured financing liabilities” to account for its obligation to return the collateral. As of June 30, 2017, the fair value of the collateral related to this program was $26.5 million and the Company has an obligation to return $26.5 million of collateral to the securities borrowers. The following table provides the amount by asset class of securities of collateral pledged for repurchase agreements and securities that have been loaned as part of securities lending transactions as of June 30, 2017 and December 31, 2016: Repurchase Agreements, Securities Lending Transactions, and Repurchase-to-Maturity Transactions Accounted for as Secured Borrowings Remaining Contractual Maturity of the Agreements As of June 30, 2017 (Dollars In Thousands) Overnight and Continuous Up to 30 days 30-90 days Greater Than 90 days Total Repurchase agreements and repurchase-to-maturity transactions U.S. Treasury and agency securities $ 336,859 $ 66,340 $ — $ — $ 403,199 Mortgage loans 26,620 — — — 26,620 Total repurchase agreements and repurchase-to-maturity transactions 363,479 66,340 — — 429,819 Securities lending transactions Corporate securities 14,886 — — — 14,886 Equity securities 10,209 — — — 10,209 Preferred stock 526 — — — 526 Total securities lending transactions 25,621 — — — 25,621 Total securities $ 389,100 $ 66,340 $ — $ — $ 455,440 Repurchase Agreements, Securities Lending Transactions, and Repurchase-to-Maturity Transactions Accounted for as Secured Borrowings Remaining Contractual Maturity of the Agreements As of December 31, 2016 (Dollars In Thousands) Overnight and Continuous Up to 30 days 30-90 days Greater Than 90 days Total Repurchase agreements and repurchase-to-maturity transactions U.S. Treasury and agency securities $ 357,705 $ 23,758 $ — $ — $ 381,463 State and municipal securities — — — — — Other asset-backed securities — — — — — Corporate securities — — — — — Equity securities — — — — — Non-U.S. sovereign debt — — — — — Mortgage loans 480,269 — — — 480,269 Total securities $ 837,974 $ 23,758 $ — $ — $ 861,732

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	6 Months Ended

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

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In 2012, the IRS proposed favorable and unfavorable adjustments to the Company's 2003 through 2007 reported taxable income. The Company protested certain unfavorable adjustments and sought resolution at the IRS' Appeals Division. In October 2015, Appeals accepted the Company's earlier proposed settlement offer. In September 2015, the IRS proposed favorable and unfavorable adjustments to the Company's 2008 through 2011 reported taxable income. The Company agreed to these adjustments. In April 2017, a routine review by Congress’ Joint Committee on Taxation, was finalized without change and the Company expects to receive an approximate $6.2 million net refund in a future period. The resulting net adjustment to the Company's current income taxes for the years 2003 through 2011 will not materially affect the Company or its effective tax rate. In July 2016, the IRS proposed favorable and unfavorable adjustments to the Company's 2012 and 2013 reported taxable income. The Company agreed to these adjustments. The resulting settlement paid in September 2016 did not materially impact the Company or its effective tax rate. There have been no material changes to the balance of unrecognized tax benefits, where the changes impact earnings, during the quarter ending June 30, 2017. The Company believes that in the next 12 months, none of the unrecognized tax benefits at June 30, 2017 will be significantly increased or reduced. In general, the Company is no longer subject to income tax examinations by taxing authorities for tax years that began before 2014. Nevertheless, certain of these pre-2014 years have pending U.S. tax refunds. Due to their size, these refunds were reviewed by Congress' Joint Committee on Taxation. In April 2017, the Company received notification that the Joint Committee review was complete and that no changes were made. The underlying federal statutes of limitations are expected to close in due course on or before September 30, 2018. Furthermore, due to the aforementioned IRS adjustments to the Company's pre-2014 taxable income, the Company is amending certain of its 2003 through 2013 state income tax returns. Such amendments will cause such years to remain open, pending the states' acceptances of the returns. During the year ended December 31, 2016, the Company entered into a reinsurance transaction. This transaction is expected to generate an operating loss on the Company’s consolidated 2016 U.S. income tax return. The Company has evaluated its ability to carry this loss back to receive refunds of previously-paid taxes, plus utilize the remaining loss in future years. The Company expects to receive refunds for substantially all of the U.S. income taxes that it paid in 2014 and 2015, as well as fully utilize the remaining operating loss carryforward during the carryforward period. Based on the Company’s current assessment of future taxable income, including available tax planning opportunities, the Company anticipates that it is more likely than not that it will generate sufficient taxable income to realize all of its material deferred tax assets. The Company did not record a valuation allowance against its material deferred tax assets as of June 30, 2017 and December 31, 2016. The Company used its respective estimates of its annual 2017 and 2016 incomes in computing its effective income tax rates for the three and six months ended June 30, 2017 and 2016 . The effective tax rates for the three and six months ended June 30, 2017 and 2016 , were 32.8% and 32.7% , 33.7% and 33.1% respectively.

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, as prescribed in the ASC Segment Reporting Topic, 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 acquired from other companies. The segment’s primary focus is on life insurance policies and annuity products that were sold to individuals. The level of the segment’s acquisition activity is predicated upon many factors, including available capital, operating capacity, potential return on capital, and market dynamics. Policies acquired through the Acquisitions segment are typically blocks of business where no new policies are being marketed. Therefore earnings and account values are expected to decline as the result of lapses, deaths, and other terminations of coverage unless new acquisitions are made. • The Annuities segment markets fixed and VA products. These products are primarily sold through broker-dealers, financial institutions, and independent agents and brokers. • The Stable Value Products segment sells fixed and floating rate funding agreements directly to the trustees of municipal bond proceeds, money market funds, bank trust departments, and other institutional investors. This segment also issues funding agreements to the FHLB, and markets 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, guaranteed asset protection (“GAP”) products, credit life and disability insurance, and specialized ancillary products to protect consumers’ investments in automobiles and recreational vehicles. GAP coverage covers the difference between the loan pay-off amount and an asset’s actual cash value in the case of a total loss. Each type of specialized ancillary product protects against damage or other loss to a particular aspect of the underlying asset. • The Corporate and Other segment primarily consists of net investment income on assets supporting our equity capital, unallocated corporate overhead and expenses not attributable to the segments above. This segment includes earnings from several non-strategic or runoff lines of business, various financing and investment-related transactions, and the operations of several small subsidiaries. The Company's management and Board of Directors analyzes and assesses the operating performance of each segment using "pre-tax adjusted operating income (loss)" and "after-tax adjusted operating income (loss)". Consistent with GAAP accounting guidance for segment reporting, pre-tax adjusted operating income (loss) is the Company's measure of segment performance. Pre-tax adjusted operating income (loss) is calculated by adjusting "income (loss) before income tax", by excluding the following items: • realized gains and losses on investments and derivatives, • changes in the GLWB embedded derivatives exclusive of the portion attributable to the economic cost of the GLWB, • actual GLWB incurred claims, and • the amortization of DAC, VOBA, and certain policy liabilities that is impacted by the exclusion of these items. The items excluded from adjusted operating income (loss) are important to understanding the overall results of operations. Pre-tax adjusted operating income (loss) and after-tax adjusted operating income (loss) are not substitutes for income before income taxes or net income (loss), respectively. These measures may not be comparable to similarly titled measures reported by other companies. The Company believes that pre-tax and after-tax adjusted operating income (loss) enhances management's and the Board of Directors' understanding of the ongoing operations, the underlying profitability of each segment, and helps facilitate the allocation of resources. 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. In filings prior to the Company's 2016 Form 10-K, "Pre-tax adjusted operating income (loss)" was referred to as "Pre-tax operating income", "Operating income before tax", or "Segment operating income". In addition, we referred to "After-tax adjusted operating income (loss)" as "After-tax operating income" or "Operating earnings". The definition of these labels remains unchanged, but the Company has modified the labels to provide further clarity that these measures are non-GAAP measures. There were no significant intersegment transactions during the three and six months ended June 30, 2017 and 2016 . The following tables presents 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 2017 2016 2017 2016 (Dollars In Thousands) Revenues Life Marketing $ 379,880 $ 384,823 $ 776,952 $ 765,897 Acquisitions 387,464 453,848 788,831 878,655 Annuities 136,863 188,597 246,719 407,113 Stable Value Products 42,087 26,237 82,930 56,139 Asset Protection 93,290 76,419 183,634 150,098 Corporate and Other 23,879 44,918 31,753 76,842 Total revenues $ 1,063,463 $ 1,174,842 $ 2,110,819 $ 2,334,744 Pre-tax Adjusted Operating Income (Loss) Life Marketing $ 24,342 25,098 44,419 $ 38,224 Acquisitions 68,278 45,285 121,945 113,938 Annuities 36,288 47,480 78,349 92,756 Stable Value Products 22,367 15,178 46,266 29,626 Asset Protection 4,674 4,141 8,624 8,397 Corporate and Other (35,325 ) (30,248 ) (69,686 ) (64,990 ) Pre-tax adjusted operating income 120,624 106,934 229,917 217,951 Realized (losses) gains on investments and derivatives 12,662 153,646 (9,987 ) 277,608 Income before income tax 133,286 260,580 219,930 495,559 Income tax expense (43,654 ) (87,787 ) (71,959 ) (164,149 ) Net income $ 89,632 $ 172,793 $ 147,971 $ 331,410 Pre-tax adjusted operating income $ 120,624 $ 106,934 $ 229,917 $ 217,951 Adjusted operating income tax (expense) benefit (39,222 ) (34,011 ) (75,454 ) (66,986 ) After-tax adjusted operating income 81,402 72,923 154,463 150,965 Realized (losses) gains on investments and derivatives 12,662 153,646 (9,987 ) 277,608 Income tax benefit (expense) on adjustments (4,432 ) (53,776 ) 3,495 (97,163 ) Net income $ 89,632 $ 172,793 $ 147,971 $ 331,410 Realized investment (losses) gains: Derivative financial instruments $ (63,794 ) $ 43,548 $ (124,694 ) $ 75,456 All other investments 53,535 88,783 76,376 170,492 Net impairment losses recognized in earnings (2,785 ) (967 ) (7,986 ) (3,584 ) Less: related amortization (1) (15,703 ) (13,073 ) (26,447 ) (17,123 ) Less: VA GLWB economic cost (10,003 ) (9,209 ) (19,870 ) (18,121 ) Realized (losses) gains on investments and derivatives $ 12,662 $ 153,646 $ (9,987 ) $ 277,608 (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. Prior to February 1, 2015, PLC’s stock was publicly traded on the New York Stock Exchange. Subsequent to the Merger date, PLC and the Company remain as SEC registrants within the United States. The Company markets individual life insurance, credit life and disability insurance, guaranteed investment contracts, guaranteed funding agreements, fixed and variable annuities, and extended service contracts throughout the United States. The Company also maintains a separate segment devoted to the acquisition of insurance policies from other companies. PLC is a holding company with subsidiaries that provide financial services through the production, distribution, and administration of insurance and investment products. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for the interim periods presented herein. Such accounting principles differ from statutory reporting practices used by insurance companies in reporting to state regulatory authorities. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements reflect all adjustments (consisting only of normal recurring items) necessary for a fair statement of the results for the interim periods presented. Operating results for the three and six months ended June 30, 2017 , are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2017 . The year-end consolidated condensed financial data included herein was derived from audited financial statements but does not include all disclosures required by GAAP within this report. 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, 2016 . The operating results of companies in the insurance industry have historically been subject to significant fluctuations due to changing competition, economic conditions, interest rates, investment performance, insurance ratings, claims, persistency, and other factors.
Entities Included	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 ASU No. 2017-04-Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This Update simplifies the goodwill impairment test by re-defining the concept of goodwill impairment as the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The Update eliminates “Step 2” of the current goodwill impairment test, which requires entities to determine goodwill impairment by calculating the implied fair value of goodwill by remeasuring to fair value the assets and liabilities of a reporting unit as if that reporting unit had been acquired in a business combination. The Company elected to adopt the amendments in the Update in the first quarter of 2017, and will apply the revised guidance to impairment tests conducted after January 1, 2017. Application of the revised guidance did not impact the Company’s financial position or results of operations and will simplify its annual goodwill impairment test, which is generally conducted in the fourth quarter. For more details regarding the Company’s goodwill assessment process, please refer to Note 9, Goodwill . ASU No. 2015-09 - Financial Services-Insurance (Topic 944): Disclosures about Short-Duration Contracts. The amendments in this Update require additional disclosures for short-duration contracts issued by insurance entities. The additional disclosures focus on the liability for unpaid claims and claim adjustment expenses and include incurred and paid claims development information by accident year in tabular form, along with a reconciliation of this information to the statement of financial position. For accident years included in the development tables, the amendments also require disclosure of the total incurred-but-not-reported liabilities and expected development on reported claims, along with claims frequency information unless impracticable. Finally, the amendments require disclosure of the historical average annual percentage payout of incurred claims. With the exception of the current reporting period, claims development information may be presented as supplementary information. The Update is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. The additional disclosures introduced in this Update have not been provided, as the short-duration lines of business to which they apply are not material to the Company’s financial statements. Accounting Pronouncements Not Yet Adopted ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606). This Update provides for significant revisions to the recognition of revenue from contracts with customers across various industries. Under the new guidance, entities are required to apply a prescribed 5-step process to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The accounting for revenues associated with insurance products is not within the scope of this Update. The Update was originally effective for annual and interim periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU No. 2015-14 - Revenues from Contracts with Customers: Deferral of the Effective Date , to defer the effective date of ASU No. 2014-09 by one year to annual and interim periods beginning after December 15, 2017. The Company will adopt this Update on January 1, 2018 using the modified retrospective approach method. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, may impact several of the Company's non-core lines of business, specifically revenues at the Company's affiliated broker dealers and insurance agency. Additionally, certain non-insurance products sold from the Asset Protection Division, such as fee-for-service arrangements, are expected to be in the scope of the revised guidance. Several application questions remain outstanding, most notably interpretive positions from the AICPA regarding the Update's application to insurance companies and products. Based on the assessment completed to date, the Company does not anticipate material financial impact from the implementation of the revised guidance. ASU No. 2016-01 - Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most notably, the Update requires that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) be measured at fair value with changes in fair value recognized in net income. The Update also introduces a single-step impairment model for equity investments without a readily determinable fair value. Additionally, the Update requires changes in instrument-specific credit risk for fair value option liabilities to be recorded in other comprehensive income. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2017 and will be applied on a modified retrospective basis. The Company expects to complete its review of applicable policies and procedures to ensure compliance with the revised guidance. ASU No. 2016-02 - Leases. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of leases. The most significant change will relate to the accounting model used by lessees. The Update will require all leases with terms greater than 12 months to be recorded on the balance sheet in the form of a lease asset and liability. The lease asset and liability will be measured at the present value of the minimum lease payments less any upfront payments or fees. The Update also requires numerous disclosure changes for which the Company is assessing the impact. The amendments in the Update are effective for annual and interim periods beginning after December 15, 2018 on a modified retrospective basis. The Company has completed an inventory of all leases in the organization and is currently assessing the impact of the Update and updating internal processes to ensure compliance with the revised guidance. ASU No. 2016-13 - Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. The amendments in this Update introduce a new current expected credit loss (“CECL”) model for certain financial assets, including mortgage loans and reinsurance receivables. The new model will not apply to debt securities classified as available-for-sale. For assets within the scope of the new model, an entity will recognize as an allowance against earnings its estimate of the contractual cash flows not expected to be collected on day one of the asset’s acquisition. The allowance may be reversed through earnings if a security recovers in value. This differs from the current impairment model, which requires recognition of credit losses when they have been incurred and recognizes a security’s subsequent recovery in value in other comprehensive income. The Update also makes targeted changes to the current impairment model for available-for-sale debt securities, which comprise the majority of the Company’s invested assets. Similar to the CECL model, credit loss impairments will be recorded in an allowance against earnings that may be reversed for subsequent recoveries in value. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2019 on a modified retrospective basis. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption, and assessing the impact this standard will have on its operations and financial results. ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include: Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2018 using the retrospective method. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption. ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company expects to complete its review of applicable policies and procedures to ensure compliance with the revised guidance. ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the Update provide a specific test by which an entity may determine whether an acquisition involves a set of assets or a business. The amendments in the Update are to be applied prospectively for periods beginning after December 15, 2017. The Company has reviewed the revised requirements, and does not anticipate that the changes will impact its policies or recent conclusions related to its acquisition activities. ASU No. 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this update require entities to disaggregate the current-service-cost component from other components of net benefit cost and present it with other current compensation costs in the income statement. The other components of net benefit cost must be presented outside of income from operations if that subtotal is presented. In addition, the Update requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. As provided for in the ASU, the Company expects to apply the provisions of the statement retrospectively for components of net periodic pension costs and prospectively for capitalization of the service costs component of net periodic costs and net periodic postretirement benefits. The Update will not impact the Company’s financial position or results of operations. The Company is reviewing its policies and processes to ensure compliance with the requirements in this Update, upon adoption. ASU No. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine whether early adoption of the revised guidance is practicable .
