PROTECTIVE LIFE INSURANCE COMPANY

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(Unaudited)

1.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. 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 months ended March 31, 2018, are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2018. 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, 2017.

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.

During the first quarter of 2018, the Company recorded an adjustment related to prior periods to correct an error pertaining to certain reinsurance allowances. The adjustment resulted in a $6.2 million increase to other liabilities, a corresponding increase in other operating expenses, and a $4.9 million decrease to net income for the three months ended March 31, 2018. The Company concluded that the adjustment was not quantitatively or qualitatively material to previously reported annual or interim periods. As a result, this adjustment was recorded by the Company within the presented interim consolidated condensed financial statements for the three months ended March 31, 2018.

2.    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, 2017. There were no significant changes to the Company's accounting policies during the three months ended March 31, 2018 other than those discussed below.

Property and Casualty Insurance Products

Property and casualty insurance products include service contract business, surety bonds, and guaranteed asset protection ("GAP"). Premiums and fees associated with service contracts and GAP products are recognized based on expected claim patterns. For all other products, premiums are generally recognized over the terms of the contract on a pro-rata basis. Commissions and fee income associated with other products are recognized as earned when the related services are provided to the customer. Unearned premium reserves are maintained for the portion of the premiums that is related to the unexpired period of the policy. Benefit reserves are recorded when insured events occur. Benefit reserves include case basis reserves for known but unpaid claims as of the balance sheet date as well as incurred but not reported ("IBNR") reserves for claims where the insured event has occurred but has not been reported to the Company as of the balance sheet date. The case basis reserves and IBNR are calculated based on historical experience and on assumptions relating to claim severity and frequency, the level of used vehicle prices, and other factors. These assumptions are modified as necessary to reflect anticipated trends.

Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers. In consideration of the amendments in this Update, the Company revised its recognition pattern for administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. The Company will recognize these fees on a claims occurrence basis in future periods. To reflect this change in accounting principle, the Company recorded a cumulative effect

9

adjustment as of January 1, 2018 that resulted in a decrease in retained earnings of $88.6 million. The pre-tax impact to each affected line item on the Company’s financial statements is reflected in the table below:

	As Reported		Previous Accounting Method
	For The Three Months Ended March 31, 2018
	(Dollars In Millions)

Amortization of deferred policy acquisition costs and value of business acquired	$	58.1	$	44.4

Accounting Pronouncements Recently 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 adopted this Update using the modified retrospective approach via a cumulative effect adjustment to retained earnings as of January 1, 2018. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, impacted certain revenues associated with the Company's Asset Protection products. The lines of business to which the revised guidance applies are not material to the Company’s financial statements. In consideration of the amendments in this Update, the Company revised its recognition pattern for administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. The Company will recognize these fees on a claims occurrence basis in future periods. To reflect this change in accounting principle, the Company recorded a cumulative effect adjustment as of January 1, 2018 that resulted in a decrease in retained earnings of $88.6 million. See above for additional discussion.

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 were applied on a modified retrospective basis. The Company recorded a cumulative-effect adjustment at the date of adoption, January 1, 2018, transferring unrealized gains and losses on available-for-sale equity securities to retained earnings from accumulated other comprehensive income. The impact of this adjustment, net of income tax, resulted in a $10.6 million increase to retained earnings and a corresponding decrease to accumulated other comprehensive income, resulting in no net impact to consolidated shareowner's equity. The Company has updated its disclosures in Note 4, Investment Operations and Note 5, Fair Value of Financial Instruments in accordance with the ASU.

ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include:Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2017 using the retrospective method. There was no financial impact.

ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. There was no impact to the Company on adoption.

ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether

10

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 did not impact the Company’s financial position, results of operations, or current disclosures.

Accounting Pronouncements Not Yet Adopted

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. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine the financial and operational impact of implementing the Update, as well as to determine whether early adoption of the revised guidance is practicable.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update are designed to permit hedge accounting to be applied to a broader range of hedging strategies as well as to more closely align hedge accounting and risk management objectives. Specific provisions include requiring changes in the fair value of a hedging instrument be recorded in the same income statement line as the hedged item when it affects earnings. In addition, after a hedge has initially qualified as an effective hedge the Update permits the use of a qualitative hedge effectiveness test in subsequent periods. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact this standard will have on its operations and financial results.

3.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

11

Block and other portions of MONY’s general account, any of MONY’s separate accounts or any affiliate of MONY without the approval of the Superintendent of The New York State Department of Financial Services (the “Superintendent”). Closed Block assets and liabilities are carried on the same basis as similar assets and liabilities held in the general account.

The excess of Closed Block liabilities over Closed Block assets (adjusted to exclude the impact of related amounts in AOCI) at the acquisition date of October 1, 2013, represented the estimated maximum future post-tax earnings from the Closed Block that would be recognized in income from continuing operations over the period the policies and contracts in the Closed Block remain in force. In connection with the acquisition of MONY, the Company developed an actuarial calculation of the expected timing of MONY’s Closed Block’s earnings as of October 1, 2013. Pursuant to the acquisition of the Company by Dai-ichi Life, this actuarial calculation of the expected timing of MONY's Closed Block earnings was recalculated and reset as February 1, 2015, along with the establishment of a policyholder dividend obligation as of such date.

If the actual cumulative earnings from the Closed Block are greater than the expected cumulative earnings, only the expected earnings will be recognized in the Company’s net income. Actual cumulative earnings in excess of expected cumulative earnings at any point in time are recorded as a policyholder dividend obligation because they will ultimately be paid to Closed Block policyholders as an additional policyholder dividend unless offset by future performance that is less favorable than originally expected. If a policyholder dividend obligation has been previously established and the actual Closed Block earnings in a subsequent period are less than the expected earnings for that period, the policyholder dividend obligation would be reduced (but not below zero). If, over the period the policies and contracts in the Closed Block remain in force, the actual cumulative earnings of the Closed Block are less than the expected cumulative earnings, only actual earnings would be recognized in income from continuing operations. If the Closed Block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from assets outside the Closed Block.

Many expenses related to Closed Block operations, including amortization of VOBA, are charged to operations outside of the Closed Block; accordingly, net revenues of the Closed Block do not represent the actual profitability of the Closed Block operations. Operating costs and expenses outside of the Closed Block are, therefore, disproportionate to the business outside of the Closed Block.

RMBS and CMBS had gross unrealized losses greater than twelve months of $18.0 million and $33.6 million, respectively, as of March 31, 2018. 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 $7.9 million as of March 31, 2018. This category predominately includes student loan backed auction rate securities whose underlying collateral is at least 97% guaranteed by the Federal Family Education Loan Program (“FFELP”). At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary.

The U.S. government-related securities and the other government-related securities had gross unrealized losses greater than twelve months of $46.9 million and $7.4 million as of March 31, 2018, respectively. 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 $62.7 million as of March 31, 2018. These declines were related to changes in interest rates.

The corporate securities category had gross unrealized losses greater than twelve months of $849.8 million as of March 31, 2018. 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 March 31, 2018, the Company had a total of 2,428 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, 2017:

The other asset-backed securities had a gross unrealized loss greater than twelve months of $5.4 million as of December 31, 2017. This category predominately includes student loan backed auction rate securities whose underlying collateral 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 U.S. government-related securities and other government-related securities had gross unrealized losses greater than twelve months of $31.5 million and $4.8 million as of December 31, 2017, respectively. 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 $43.9 million as of December 31, 2017. These declines were related to changes in interest rates.

The corporate securities category had gross unrealized losses greater than twelve months of $471.8 million as of December 31, 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 ofMarch 31, 2018, the Company had securities in its available-for-sale portfolio which were rated below investment grade of $1.8 billion and had an amortized cost of $1.8 billion. In addition, included in the Company’s trading portfolio, the Company held $217.2 million of securities which were rated below investment grade. Approximately $306.5 million of the available-for-sale and trading securities that were below investment grade were not publicly traded.

During the three months ended March 31, 2018 and 2017, the Company recorded no other-than-temporary impairments on held-to-maturity securities.

The Company’s held-to-maturity securities had$30.3 million of gross unrecognized holding gains and $56.0 million of gross unrecognized holding losses by maturity as of March 31, 2018. The Company does not consider these unrecognized holding losses to be other-than-temporary based on certain positive factors associated with the securities which include credit ratings of the guarantor, financial health of the issuer and guarantor, continued access of the issuer to capital markets and other pertinent information. 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 $76.6 million of gross unrecognized holding gains and $19.2 million of gross unrecognized holding losses by maturity as of December 31, 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.

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.

20

Based on this analysis, the Company had an interest in one wholly owned subsidiary, Red Mountain, LLC ("Red Mountain") as of March 31, 2018 and December 31, 2017, 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 March 31, 2018, no payments have been made or required related to this guarantee.

5.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.

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.

23

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 approximately92.4%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 three months ended March 31, 2018.

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 mainlyconsists of residential mortgage-backed securities, commercial mortgage-backed securities, and other asset-backed securities (collectively referred to as asset-backed securities or “ABS”). As ofMarch 31, 2018, the Company held$5.4 billionof 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 ofMarch 31, 2018, the Company held $538.7 million of Level 3 ABS, which included $503.8 million of other asset-backed securities classified as available-for-sale and $34.9 million of other asset-backed securities classified as trading. These securities are predominantly ARS whose underlying collateral is at least97%guaranteed by the FFELP. 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 March 31, 2018, the Company classified approximately $32.1 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 March 31, 2018, the Company classified approximately $631.7 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 March 31, 2018, the Company held approximately $65.5 million of equity securities classified as Level 2 and Level 3. Of this total, $65.5 million represents Federal Home Loan Bank (“FHLB”) stock. The Company believes that the cost of the FHLB stock approximates fair value.

Other Long-Term Investments and Other Liabilities

Other long-term investments and other liabilities consist entirely of free-standing and embedded derivative financial instruments. Refer to Note 6,Derivative Financial Instrumentsfor 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 ofMarch 31, 2018,82.6% of derivatives based upon notional values were priced using exchange prices or independent broker quotations. The remaining derivatives were priced by pricing valuation models, which utilize observable market data inputs to the extent they are available. Inputs used to value derivatives include, but are not limited to, interest swap rates, credit spreads, interest rate and equity market volatility indices, equity index levels, and treasury rates. The Company performs monthly analysis on derivative valuations that includes both quantitative and qualitative analyses.

Derivative instruments classified as Level 1 generally include futures and options, which are traded on active exchange markets.

Derivative instruments classified as Level 2 primarily include swaps, options, and swaptions, which are traded over-the-counter. Level 2 also includes certain centrally cleared derivatives. These derivative valuations are determined using independent broker quotations, which are corroborated with observable market inputs.

Derivative instruments classified as Level 3 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 guaranteed living withdrawal benefits ("GLWB") embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using multiple risk neutral stochastic equity scenarios and policyholder behavior assumptions. The risk neutral scenarios are generated using the current swap curve and projected equity volatilities and correlations. The projected equity volatilities are based on a blend of historical volatility and near- term equity market implied volatilities. The equity correlations are based on historical price observations. For policyholder behavior assumptions, expected lapse and utilization assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from theRuark 2015 ALB table with attained age factors varying from 91.1% - 106.6%. The present value of the cash flows is determined using the discount rate curve, which is based uponLIBORplus 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.

25

The balance of the FIA embedded derivative is impacted by policyholder cash flows associated with the FIA product that are allocated to the embedded derivative in addition to changes in the fair value of the embedded derivative during the reporting period. The fair value of the FIA embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using current index values and volatility, the hedge budget used to price the product, and policyholder assumptions (both elective and non-elective). For policyholder behavior assumptions, expected lapse and withdrawal assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the 1994 Variable Annuity MGDB mortality table modified with company experience, with attained age factors varying from 46% - 113%. The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR up to one year and constant maturity treasury rates plus a credit spread (to represent the Company’s non-performance risk) thereafter. Policyholder 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 34% - 152%. The present value of the cash flows is determined using the discount rate curve, which is baseduponLIBORup 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 also reported in earnings. As of March 31, 2018, 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 $134.1 million. As a result, changes in the fair value of the embedded derivatives are largely offset by the changes in fair value of the related investments and each are reported in earnings. The fair value of the embedded derivative is considered a Level 3 valuation due to the unobservable nature of the policy liabilities.

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 March 31, 2018 was $103.1 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 $48.8 million as of March 31, 2018. As of March 31, 2018, no payments have been made under this agreement, however, certain interest support agreement obligations to Golden Gate II of approximately $4.8 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.

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 March 31, 2018 was $49.4 million. As of March 31, 2018, 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 March 31, 2018, was $4.8 million. As of March 31, 2018, 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 March 31, 2018, was a liability of $101.8 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 March 31, 2018 is $81.4 million.

Separate Accounts

Separate account assets are invested in open-ended mutual funds and are included in Level 1.

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 March 31, 2018, but the valuation techniques and inputs used by somebrokers in pricing certain financial instruments are not shared with the Company. This resulted in $49.1 million of financial instruments being classified as Level 3 as of March 31, 2018. Of the $49.1 million, $35.1 million are other asset-backed securities, and $14.0 million are corporate securities.

In certain cases the Company has determined that book value materially approximates fair value. As of March 31, 2018, the Company held $65.5 million of financial instruments where book value approximates fair value which were predominantly FHLB stock.

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 December 31, 2017, but the valuation techniques and inputs used by some brokers in pricing certain financial instruments are not shared with the Company. This resulted in $50.0 million of financial instruments being classified as Level 3 as of December 31, 2017. Of the $50.0 million, $35.4 million are other asset backed securities and $14.6 million are corporate securities.

In certain cases the Company has determined that book value materially approximates fair value. As of December 31, 2017, the Company held $65.5 million of financial instruments where book value approximates fair value which are predominantly FHLB stock.

The asset-backed securities classified as Level 3 are predominantly ARS. A change in the paydown rate (the projected annual rate of principal reduction) of the ARS can significantly impact the fair value of these securities. A decrease in the paydown rate would increase the projected weighted average life of the ARS and increase the sensitivity of the ARS’ fair value to changes in interest rates. An increase in the liquidity premium would result in a decrease in the fair value of the securities, while a decrease in the liquidity premium would increase the fair value of these securities. The liquidation value for these securities are sensitive to the issuer's available cash flows and ability to redeem the securities, as well as the current holders' willingness to liquidate at the specified prices.

The fair value of corporate bonds classified as Level 3 is sensitive to changes in the interest rate spread over the corresponding U.S. Treasury rate. This spread represents a risk premium that is impacted by company specific and market factors. An increase in the spread can be caused by a perceived increase in credit risk of a specific issuer and/or an increase in the overall market risk premium associated with similar securities. The fair values of corporate bonds are sensitive to changes in spread. When holding the treasury rate constant, the fair value of corporate bonds increases when spreads decrease and decreases when spreads increase.

28

The fair value of the GLWB embedded derivative is sensitive to changes in the discount rate which includes the Company’s nonperformance risk, volatility, lapse, and mortality assumptions. The volatility assumption is an observable input as it is based on market inputs. The Company’s nonperformance risk, lapse, and mortality are unobservable. An increase in the three unobservable assumptions would result in a decrease in the fair value of the liability and conversely, if there is a decrease in the assumptions the fair value would increase. The fair value is also dependent on the assumed policyholder utilization of the GLWB where an increase in assumed utilization would result in an increase in the fair value of the liability and conversely, if there is a decrease in the assumption, the fair value would decrease.

The fair value of the FIA embedded derivative is predominantly impacted by observable inputs such as discount rates and equity returns. However, the fair value of the FIA embedded derivative is sensitive to non-performance risk, which is unobservable. The value of the liability increases with decreases in the discount rate and non-performance risk and decreases with increases in the discount rate and nonperformance risk. The value of the liability increases with increases in equity returns and the liability decreases with a decrease in equity returns.

The fair value of the IUL embedded derivative is predominantly impacted by observable inputs such as discount rates and equity returns. However, the fair value of the IUL embedded derivative is sensitive to non-performance risk, which is unobservable. The value of the liability increases with decreases in the discount rate and non-performance risk and decreases with increases in the discount rate and non-performance risk. The value of the liability increases with increases in equity returns and the liability decreases with a decrease in equity returns.

For the three months ended March 31, 2017, there were an immaterial amount of securities transferred into Level 3.

For the three months ended March 31, 2017, $9.3 million of securities transferred into Level 2. This amount was transferred from Level 3. These transfers resulted from securities that were priced internally using significant unobservable inputs where market observable inputs were not available in previous periods but were priced by independent pricing services or brokers as of March 31, 2017.

For the three months ended March 31, 2017, there were no securities transferred from Level 2 to Level 1.

For the three months ended March 31, 2017, there were no securities transferred from Level 1.

     Total realized and unrealized gains (losses) on Level 3 assets and liabilities are primarily reported in either realized investment gains (losses) within the consolidated condensed statements of income (loss) or other comprehensive income (loss) within shareowner’s equity based on the appropriate accounting treatment for the item.

Purchases, sales, issuances, and settlements, net, represent the activity that occurred during the period that results in a change of the asset or liability but does not represent changes in fair value for the instruments held at the beginning of the period. Such activity primarily relates to purchases and sales of fixed maturity securities and issuances and settlements of fixed indexed annuities.

31

The Company reviews the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. The asset transfers in the table(s) above primarily related to positions moved from Level 3 to Level 2 as the Company determined that certain inputs were observable.

The amount of total gains (losses) for assets and liabilities still held as of the reporting date primarily represents changes in fair value of trading securities and certain derivatives that exist as of the reporting date and the change in fair value of fixed indexed annuities.

Fair Value Measurements

Mortgage loans on real estate

The Company estimates the fair value of mortgage loans using an internally developed model. This model includes inputs derived by the Company based on assumed discount rates relative to the Company’s current mortgage loan lending rate and an expected cash flow analysis based on a review of the mortgage loan terms. The model also contains the Company’s determined representative risk adjustment assumptions related to credit and liquidity risks.

Policy loans

The Company believes the fair value of policy loans approximates book value. Policy loans are funds provided to policy holders in return for a claim on the policy. The funds provided are limited to the cash surrender value of the underlying policy. The nature of policy loans is to have a negligible default risk as the loans are fully collateralized by the value of the policy. Policy loans do not have a stated maturity and the balances and accrued interest are repaid either by the policyholder or with proceeds from the policy. Due to the collateralized nature of policy loans and unpredictable timing of repayments, the Company believes the fair value of policy loans approximates carrying value.

Fixed maturities, held-to-maturity

The Company estimates the fair value of its fixed maturity, held-to-maturity securities using internal discounted cash flow models. The discount rates used in the model are based on a current market yield for similar financial instruments.

The Company estimates the fair value of stable value product account balances and other investment contract balances (included in Future policy benefits and claims as well as Other policyholder funds line items on our balance sheet) using models based on discounted expected cash flows. The discount rates used in the models are based on a current market rate for similar financial instruments.

Non-recourse funding obligations

The Company estimates the fair value of its non-recourse funding obligations using internal discounted cash flow models. The discount rates used in the model are based on a current market yield for similar financial instruments.

6.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.

33

For a derivative financial instrument to be accounted for as an accounting hedge, it must be identified and documented as such on the date of designation. For cash flow hedges, the effective portion of their realized gain or loss is reported as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain attributable to the hedged risk of the hedged item is recognized in current earnings. Effectiveness of the Company’s hedge relationships is assessed on a quarterly basis.

The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship through earnings in the period of change. Changes in the fair value of derivatives that are recognized in current earnings are reported in “Realized investment gains (losses)-Derivative financial instruments.”

Derivative Instruments Designated and Qualifying as Hedging Instruments

Cash-Flow Hedges

• To hedge a fixed rate note denominated in a foreign currency, the Company entered into a fixed-to-fixed foreign currency swap in order to hedge the foreign currency exchange risk associated with the note. The cash flows received on the swap are identical to the cash flow paid on the note.

Derivative Instruments Not Designated and Not Qualifying as Hedging Instruments

The Company uses various other derivative instruments for risk management purposes that do not qualify for hedge accounting treatment. Changes in the fair value of these derivatives are recognized in earnings during the period of change.

Derivatives Related to Variable Annuity Contracts

• The Company uses equity futures, equity options, total return swaps, interest rate futures, interest rate swaps, interest rate swaptions, currency futures, volatility futures, volatility options, and variance swaps to mitigate the risk related to certain guaranteed minimum benefits, including GLWB, within its VA products. In general, the cost of such benefits varies with the level of equity and interest rate markets, foreign currency levels, and overall volatility.

• The Company markets certain VA products with a GLWB rider. The GLWB component is considered an embedded derivative, not considered to be clearly and closely related to the host contract.

• The Company has a funds withheld account that consists of various derivative instruments held by the Company that are used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument.

Derivatives Related to Fixed Annuity Contracts

• The Company uses equity futures and options to mitigate the risk within its fixed indexed annuity products. In general, the cost of such benefits varies with the level of equity 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.

7.    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.

8.MORTGAGE LOANS

Mortgage Loans

The Company invests a portion of its investment portfolio in commercial mortgage loans. As of March 31, 2018, the Company’s mortgage loan holdings were approximately$6.8 billion. The Company has specialized in making loans on credit-oriented commercial properties, credit-anchored strip shopping centers, senior living facilities, and apartments. The Company’s underwriting procedures relative to its commercial loan portfolio are based, in the Company’s view, on a conservative and disciplined approach. The Company concentrates on a small number of commercial real estate asset types associated with the necessities of life (retail, multi-family, senior living, professional office buildings, and warehouses). The Company believes that these asset types tend to weather economic downturns better than other commercial asset classes in which it has chosen not to participate. The Company believes this disciplined approach has helped to maintain a relatively low delinquency and foreclosure rate throughout its history. The majority of the Company's mortgage loans portfolio was underwritten by the Company. From time to time, the Company may acquire loans in conjunction with an acquisition.

The Company's commercial mortgage loans are stated at unpaid principal balance, adjusted for any unamortized premium or discount, and net of valuation allowances. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Amortization of premiums and discounts is recorded using the effective yield method. Interest income, amortization of premiums and discounts and prepayment fees are reported in net investment income.

Certain of the mortgage loans have call options that occur within the next 12years. 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 March 31, 2018, assuming the loans are called at their next call dates, approximately $143.6 million of principal would become due for the remainder of 2018, $873.1 million in 2019 through 2023, $105.0 million in 2024 through 2028, and $2.0 million thereafter.

The Company offers a type of commercial mortgage loan under which the Company will permit a loan-to-value ratio of up to85%in exchange for a participating interest in the cash flows from the underlying real estate. As ofMarch 31, 2018, andDecember 31, 2017, approximately $672.1 million and $669.3 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 thethreemonths endedMarch 31, 2018and2017, the Company recognized$7.3 million and $6.8 million, respectively, of participating mortgage loan income.

40

As ofMarch 31, 2018,noneof the Company's invested assets consisted of nonperforming mortgage loans, restructured mortgage loans, or mortgage loans that were foreclosed and were converted to real estate properties. For all mortgage loans, the impact of troubled debt restructurings is generally reflected in our investment balance and in the allowance for mortgage loan credit losses. During the three months ended March 31, 2018, the Company recognized no troubled debt restructurings and the Company did not identify any loans whose principal was permanently impaired.

TheCompany’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 March 31, 2018, the Company did not have mortgage loans not subject to a pooling and servicing agreement that were nonperforming mortgage loans, restructured, or mortgage loans that were foreclosed and were converted to real estate properties. The Company did not foreclose on any nonperforming loans not subject to a pooling and servicing agreement during the three months ended March 31, 2018.

As of March 31, 2018,noneof the loans subject to a pooling and servicing agreement were nonperforming or restructured. The Company did not foreclose on any nonperforming loans subject to a pooling and servicing agreement during the three months ended March 31, 2018.

As of March 31, 2018 and December 31, 2017, there were no allowances for mortgage loan credit losses. Due to the Company’s loss experience and nature of the loan portfolio, the Company believes that a collectively evaluated allowance would be inappropriate. The Company believes an allowance calculated through an analysis of specific loans that are believed to have a higher risk of credit impairment provides a more accurate presentation of expected losses in the portfolio and is consistent with the applicable guidance for loan impairments in ASC Subtopic 310. Since the Company uses the specific identification method for calculating the allowance, it is necessary to review the economic situation of each borrower to determine those that have higher risk of credit impairment. The Company has a team of professionals that monitors borrower conditions such as payment practices, borrower credit, operating performance, and property conditions, as well as ensuring the timely payment of property taxes and insurance. Through this monitoring process, the Company assesses the risk of each loan. When issues are identified, the severity of the issues are assessed and reviewed for possible credit impairment. If a loss is probable, an expected loss calculation is performed and an allowance is established for that loan based on the expected loss. The expected loss is calculated as the excess carrying value of a loan over either the present value of expected future cash flows discounted at the loan’s original effective interest rate, or the current estimated fair value of the loan’s underlying collateral. A loan may be subsequently charged off at such point that the Company no longer expects to receive cash payments, the present value of future expected payments of the renegotiated loan is less than the current principal balance, or at such time that the Company is party to foreclosure or bankruptcy proceedings associated with the borrower and does not expect to recover the principal balance of the loan.

A charge off is recorded by eliminating the allowance against the mortgage loan and recording the renegotiated loan or the collateral property related to the loan as investment real estate on the balance sheet, which is carried at the lower of the appraised fair value of the property or the unpaid principal balance of the loan, less estimated selling costs associated with the property. The Company did not have any charge offs or recovery for the three months ended March 31, 2018. 

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. 

					Greater
	30-59 Days		60-89 Days		than 90 Days		Total
As of March 31, 2018	Delinquent		Delinquent		Delinquent		Delinquent

As of December 31, 2017

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

Mortgage loans that were modified in a troubled debt restructuring as of March 31, 2018 and December 31, 2017 were as follows:

9.GOODWILL

The balance of goodwill for the Company as of March 31, 2018 was $793.5 million. There has been no change to goodwill during the three months ended March 31, 2018.

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 2017, the Company performed its annual evaluation of goodwill based on information as of October 1, 2017, and determined that no adjustment to impair goodwill was necessary. During the three months ended March 31, 2018, 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.

10.DEBT AND OTHER OBLIGATIONS

The Company has the ability to borrow on an unsecured basis up to an aggregate principal amount of $1.0 billion under a Credit Facility. 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 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 annual facility fee rate is 0.125% of the aggregate principal amount. The Credit Facility provides that PLC is liable for the full amount of any obligations for borrowings or letters of credit, including those of the Company, under the Credit Facility. The maturity date of the Credit Facility is February 2, 2020. The Company is not aware of any non-compliance with the financial debt covenants of the Credit Facility as of March 31, 2018. PLC had an outstanding balance of $325.0 million bearing interest at a rate of LIBOR plus 1.00% as of March 31, 2018.

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 than90 days. The market value of securities to be repurchased is monitored and collateral levels are adjusted where appropriate to protect the counterparty against credit exposure. Cash received is invested in fixed maturity securities, and the agreements provided for net settlement in the event of default or on termination of the agreements. As of March 31, 2018, the fair value of securities pledged under the repurchase program was $753.6 million, and the repurchase obligation of $665.0 million was included in the Company’s consolidated condensed balance sheets (at an average borrowing rate of 173 basis points). During the three months ended March 31, 2018, the maximum balance outstanding at any one point in time related to these programs was $885.0 million. The average daily balance was $808.0 million (at an average borrowing rate of149basis points) during thethreemonths endedMarch 31, 2018. As ofDecember 31, 2017, the fair value of securities pledged under the repurchase program was $1,006.6 million, and the repurchase obligation of $885.0 million was included in the Company's consolidated condensed balance sheets (at an average borrowing rate of142basis points). During2017, the maximum balance outstanding at any one point in time related to these programs was $988.5 million. The average daily balance was$624.7 million(at an average borrowing rate of101basis points) during the year endedDecember 31, 2017.

43

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 March 31, 2018, securities with a market value of $107.0 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 March 31, 2018, the fair value of the collateral related to this program was $113.9 million and the Company has an obligation to return $113.9 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 March 31, 2018 and December 31, 2017:

11.COMMITMENTS AND CONTINGENCIES

44

Under the insurance guaranty fund laws in most states, insurance companies doing business therein can be assessed up to prescribed limits for policyholder losses incurred by insolvent companies. From time to time, companies may be asked to contribute amounts beyond prescribed limits. It is possible that the Company could be assessed with respect to product lines not offered by the Company. In addition, legislation may be introduced in various states with respect to guaranty fund assessment laws related to insurance products, including long term care insurance and other specialty products, that increases the cost of future assessments or alters future premium tax offsets received in connection with guaranty fund assessments. The Company cannot predict the amount, nature or timing of any future assessments or legislation, any of which could have a material and adverse impact on the Company's financial condition or results of operations.

A number of civil jury verdicts have been returned against insurers, broker-dealers, and other providers of financial services involving sales, refund or claims practices, alleged agent misconduct, failure to properly supervise representatives, relationships with agents or persons with whom the insurer does business, and other matters. Often these lawsuits have resulted in the award of substantial judgments that are disproportionate to the actual damages, including material amounts of punitive and non-economic compensatory damages. In some states, juries, judges, and arbitrators have substantial discretion in awarding punitive and non-economic compensatory damages which creates the potential for unpredictable material adverse judgments or awards in any given lawsuit or arbitration. Arbitration awards are subject to very limited appellate review. In addition, in some class action and other lawsuits, companies have made material settlement payments. The financial services and insurance industries in particular are also sometimes the target of law enforcement and regulatory investigations relating to the numerous laws and regulations that govern such companies. Some companies have been the subject of law enforcement or regulatory actions or other actions resulting from such investigations. The Company, in the ordinary course of business, is involved in such matters.

The Company establishes liabilities for litigation and regulatory actions when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. For matters where a loss is believed to be reasonably possible, but not probable, no liability is established. For such matters, the Company may provide an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made. The Company reviews relevant information with respect to litigation and regulatory matters on a quarterly and annual basis and updates its established liabilities, disclosures and estimates of reasonably possible losses or range of loss based on such reviews.

The Company and certain of its insurance subsidiaries, as well as certain other insurance companies for which the Company has coinsured blocks of life insurance and annuity policies, are under audit for compliance with the unclaimed property laws of a number of states. The audits are being conducted on behalf of the treasury departments or unclaimed property administrators in such states. The focus of the audits is on whether there have been unreported deaths, maturities, or policies that have exceeded limiting age with respect to which death benefits or other payments under life insurance or annuity policies should be treated as unclaimed property that should be escheated to the state. The Company is presently unable to estimate the reasonably possible loss or range of loss that may result from the audits due to a number of factors, including uncertainty as to the legal theory or theories that may give rise to liability, the early stages of the audits being conducted, and uncertainty as to whether the Company or other companies are responsible for the liabilities, if any, arising in connection with certain co-insured policies. The Company will continue to monitor the matter for any developments that would make the loss contingency associated with the audits reasonably estimable.

The Company and certain of its insurance 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.

During the three months ended March 31, 2018, PLC did not make a contribution to its defined benefit pension plan. PLC will make contributions in future periods as necessary to at least satisfy minimum funding requirements, to maintain an adjusted funding target attainment percentage ("AFTAP") of at least 80% and to avoid certain Pension Benefit Guaranty Corporation (“PBGC”) reporting triggers. PLC may also make additional discretionary contributions in excess of the contribution amounts established by the current funding policy.

14.INCOME TAXES

The Company used its respective estimates for its annual 2018 and 2017 incomes in computing its effective income tax rates for the three months ended March 31, 2018 and 2017. The estimate of the annual 2018 income excluded unrealized gains and losses on equity securities due to an inability to forecast future gains and losses. The Company's effective tax rate related to continuing operations varied from the maximum federal income tax rates as follows:

	For The Three Months Ended March 31,
	2018		2017
Statutory federal income tax rate applied to pre-tax income	21.0	%	35.0	%
State income taxes	0.4		0.5
Investment income not subject to tax	(3.3	)	(3.4	)
Unrealized tax positions	—		0.1
Other	(1.4	)	0.5
	16.7	%	32.7	%

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 received an approximate $6.2 million net refund in the fourth quarter of 2017. The resulting net adjustment to the Company's current income taxes for the years 2003 through 2011 did not materially affect the Company or its effective tax rate.

In July 2016, the IRS proposed favorable and unfavorable adjustments to the Company's 2012 and 2013 reported taxable income. The Company agreed to these adjustments. The resulting settlement paid in September 2016 did not materially impact the Company or its effective tax rate.

There have been no material changes to the balance of unrecognized tax benefits, where the changes impact earnings, during the quarter ending March 31, 2018. The Company believes that in the next twelve months, none of the unrecognized tax benefits will be reduced.

In general, the Company is no longer subject to income tax examinations by taxing authorities for tax years that began before 2014. Furthermore, due to the aforementioned IRS adjustments to the Company's pre-2014 taxable income, the Company

48

has amended certain of its 2003 through 2013 state income tax returns. Such amendments will cause such years to remain open, pending the states' acceptances of the returns.

During the year ended December 31, 2016, the Company entered into a reinsurance transaction. This transaction generated an operating loss on the Company’s consolidated 2016 U.S. income tax return. The Company partially carried back this loss and received refunds for substantially all of the U.S. income taxes it paid in 2014 and 2015 and expects to 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 March 31, 2018 and December 31, 2017.

In the tax year ended December 31, 2017, the Company recognized provisional impacts related to the revaluation of certain deferred tax assets under the Tax Reform Act under Staff Accounting Bulletin No. 118. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional regulatory guidance that may be issued, additional analysis, and resulting changes in interpretations and assumptions the Company has made. Any adjustments to these provisional amounts will be reported as a component of income tax expense (benefit) in the reporting period in which any such adjustments are determined. There are no such adjustments for the three months ended March 31, 2018. The accounting is expected to be complete by December 22, 2018.

15.OPERATINGSEGMENTS

The Company has several operating segments, each having a strategic focus. An operating segment is distinguished by products, channels of distribution, and/or other strategic distinctions. The Company periodically evaluates its operating segments and makes adjustments to its segment reporting as needed. A brief description of each segment follows.

• The Life Marketing segment markets fixed universal life (“UL”), indexed universal life ("IUL"), variable universal life (“VUL”), bank-owned life insurance (“BOLI”), and level premium term insurance (“traditional”) products on a national basis primarily through networks of independent insurance agents and brokers, broker-dealers, financial institutions, independent marketing organizations, and affinity groups.

• The Acquisitions segment focuses on acquiring, converting, and servicing policies and contracts acquired from other companies. The segment’s primary focus is on life insurance policies and annuity products that were sold to individuals. The level of the segment’s acquisition activity is predicated upon many factors, including available capital, operating capacity, potential return on capital, and market dynamics. Policies acquired through the Acquisitions segment are typically blocks of business where no new policies are being marketed. 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, GAP products, credit life and disability insurance, and other specialized ancillary products to protect consumers’ investments in automobiles and recreational vehicles. GAP products are designed to cover the difference between the scheduled loan pay-off amount and an asset’s actual cash value in the case of a total loss. Each type of specialized ancillary product protects against damage or other loss to a particular aspect of the underlying asset.

• The Corporate and Other segment primarily consists of net investment income on assets supporting our equity capital, unallocated corporate overhead and expenses not attributable to the segments above. This segment includes earnings from several non-strategic or runoff lines of business, various financing and investment-related transactions, and the operations of several small subsidiaries.

 The Company's management and Board of Directors analyzes and assesses the operating performance of each segment using "pre-tax adjusted operating income (loss)" and "after-tax adjusted operating income (loss)". Consistent with GAAP accounting guidance for segment reporting, pre-tax adjusted operating income (loss) is the Company's measure of segment performance. Pre-tax adjusted operating income (loss) is calculated by adjusting "income (loss) before income tax", by excluding the following items:

• realized gains and losses on investments and derivatives,

• changes in the GLWB embedded derivatives exclusive of the portion attributable to the economic cost of the GLWB,

• actual GLWB incurred claims, and

• the amortization of deferred acquisition costs ("DAC"), value of business acquired ("VOBA"), and certain policy liabilities that is impacted by the exclusion of these items.

The items excluded from adjusted operating income (loss) are important to understanding the overall results of operations. Pre-tax adjusted operating income (loss) and after-tax adjusted operating income (loss) are not substitutes for income before income

49

taxes or net income (loss), respectively. These measures may not be comparable to similarly titled measures reported by other companies. The Company believes that pre-tax and after-tax adjusted operating income (loss) enhances management's and the Board of Directors' understanding of the ongoing operations, the underlying profitability of each segment, and helps facilitate the allocation of resources.

After-tax adjusted operating income (loss) is derived from pre-tax adjusted operating income (loss) with the inclusion of income tax expense or benefits associated with pre-tax adjusted operating income. Income tax expense or benefits is allocated to the items excluded from pre-tax adjusted operating income (loss) at the statutory federal income tax rate for the associated period. For periods ending on and prior to December 31, 2017, a rate of 35% was used. Beginning in 2018, a statutory federal income tax rate of 21% will be used to allocate income tax expense or benefits to items excluded from pre-tax adjusted operating income (loss). Income tax expense or benefits allocated to after-tax adjusted operating income (loss) can vary period to period based on changes in the Company's effective income tax rate.

In determining the components of the pre-tax adjusted operating income (loss) for each segment, premiums and policy fees, other income, benefits and settlement expenses, and amortization of DAC and VOBA are attributed directly to each operating segment. Net investment income is allocated based on directly related assets required for transacting the business of that segment. Realized investment gains (losses) and other operating expenses are allocated to the segments in a manner that most appropriately reflects the operations of that segment. Investments and other assets are allocated based on statutory policy liabilities net of associated statutory policy assets, while DAC/VOBA and goodwill are shown in the segments to which they are attributable.

There were no significant intersegment transactions during the three months ended March 31, 2018 and 2017.

16.SUBSEQUENT EVENTS

The Company has evaluated the effects of events subsequent to March 31, 2018, and through the date we filed our consolidated condensed financial statements with the United States Securities and Exchange Commission. All accounting and disclosure requirements related to subsequent events are included in our consolidated condensed financial statements.

On May 1, 2018, The Lincoln National Life Insurance Company ("Lincoln Life") completed its previously announced acquisition (the “Closing”) of Liberty Mutual Group Inc.’s (“Liberty Mutual”) Group Benefits Business and Individual Life and Annuity Business (the “Life Business”) through the acquisition of all of the issued and outstanding capital stock of Liberty Life Assurance Company of Boston (“Liberty”). In connection with the Closing and pursuant to the Master Transaction Agreement, dated January 18, 2018 (the “Master Transaction Agreement”), previously reported in the Company's Current Report on Form 8-K filed on January 23, 2018, the Company, a wholly owned subsidiary of PLC, and Protective Life and Annuity Insurance Company (“PLAIC”), a wholly owned subsidiary of the Company, entered into reinsurance agreements (the “Reinsurance Agreements”) and related ancillary documents (including administrative services agreements and transition services agreements) providing for the reinsurance and administration of the Life Business. 

Pursuant to the Reinsurance Agreements, Liberty ceded to the Company and PLAIC the insurance policies related to the Life Business on a 100% coinsurance basis. The aggregate ceding commission for the reinsurance of the Life Business was $422.9 million. All policies issued in states other than New York were ceded to the Company under a reinsurance agreement between Liberty and the Company, and all policies issued in New York were ceded to PLAIC under a reinsurance agreement between Liberty and PLAIC.  The aggregate statutory reserves of Liberty ceded to the Company and PLAIC as of the closing of the

52

Transaction were approximately $13.3 billion, which amount was based on initial estimates and is subject to adjustment following the Closing.  Pursuant to the terms of the Reinsurance Agreements, each of the Company and PLAIC are required to maintain assets in trust for the benefit of Liberty to secure their respective obligations to Liberty under the Reinsurance Agreements. The trust accounts were initially funded by each of the Company and PLAIC principally with the investment assets that were received from Liberty. Additionally, the Company and PLAIC have each agreed to provide, on behalf of Liberty, administration and policyholder servicing of the Life Business reinsured by it pursuant to administrative services agreements between Liberty and each of the Company and PLAIC.

On May 3, 2018, PLC and the Company (together with PLC, the “Borrowers”) entered into the First Amendment (the “First Amendment”) to the Amended and Restated Credit Agreement dated February 2, 2015 (the “Credit Agreement”) with the several lenders from time to time a party thereto (collectively, the “Lenders”) and with Regions Bank in its capacity as Administrative Agent for the Lenders (the “Administrative Agent”). The Credit Agreement, as amended by the First Amendment, continues to provide for a $1 billion, five-year unsecured revolving credit facility (the “Credit Facility”), including a $500 million sublimit for the potential issuance of letters of credit and a $50 million sublimit for swingline advances. Borrowings made available under the Credit Facility may be used for general corporate purposes, including the refinancing of indebtedness. The First Amendment, among other things, extends the commitment termination date and final maturity date under the Credit Agreement from February 2, 2020 to May 3, 2023, allows the Borrowers in certain circumstances to request that the commitment amount under the Credit Facility be increased to a maximum amount of $1.5 billion (increased from the maximum $1.25 billion amount originally provided in the Credit Agreement), and changes the reference dates and base amounts used to calculate the minimum Adjusted Consolidated Net Worth that PLC is required to maintain under the Credit Agreement.

OVERVIEW

Our Business

We are a wholly owned subsidiary of Protective Life Corporation (“PLC”). Founded in 1907, we are the largest operating subsidiary of PLC. 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, PLC and the Company remain SEC registrants for financial reporting purposes in the United States. We provide financial services through the production, distribution, and administration of insurance and investment products. Unless the context otherwise requires, the “Company,” “we,” “us,” or “our” refers to the consolidated group of Protective Life Insurance Company and our subsidiaries.

We have several operating segments, each having a strategic focus. An operating segment is distinguished by products, channels of distribution, and/or other strategic distinctions. We periodically evaluate our operating segments and make adjustments to our segment reporting as needed.

Our operating segments are Life Marketing, Acquisitions, Annuities, Stable Value Products, Asset Protection, and Corporate and Other.

54

• Life Marketing- We market 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 distribution organizations, and affinity groups.

• Acquisitions - We focus on acquiring, converting, and/or servicing policies and contracts from other companies. This 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.

• Annuities - We market fixed and variable annuity (“VA”) products. These products are primarily sold through broker-dealers, financial institutions, and independent agents and brokers.

• Stable Value Products - We sell fixed and floating rate funding agreements directly to the trustees of municipal bond proceeds, money market funds, bank trust departments, and other institutional investors. The segment also issues funding agreements to the Federal Home Loan Bank (“FHLB”), and markets guaranteed investment contracts (“GICs”) to 401(k) and other qualified retirement savings plans. We also have an unregistered funding agreement-backed notes program which provides for offers of notes to both domestic and international institutional investors.

• Asset Protection - We market extended service contracts, guaranteed asset protection ("GAP") products, credit life and disability insurance, and other specialized ancillary products to protect consumers’ investments in automobiles and recreational vehicles. GAP products are designed to cover the difference between the scheduled loan pay-off amount and an asset’s actual cash value in the case of a total loss. Each type of specialized ancillary product protects against damage or other loss to a particular aspect of the underlying asset.

• Corporate and Other - This 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, financing and investment-related transactions, and the operations of several small subsidiaries.

RECENT DEVELOPMENTS

On May 1, 2018, The Lincoln National Life Insurance Company (“Lincoln Life”) completed its previously announced acquisition (the “Closing”) of Liberty Mutual Group Inc.’s (“Liberty Mutual”) Group Benefits Business and Individual Life and Annuity Business (the “Life Business”) through the acquisition of all of the issued and outstanding capital stock of Liberty Life Assurance Company of Boston (“Liberty”). In connection with the Closing and  pursuant to the Master Transaction Agreement, dated January 18, 2018 (the “Master Transaction Agreement”), previously reported in the Company's Current Report on Form 8-K filed on January 23, 2018, the Company, a wholly owned subsidiary of PLC, and Protective Life and Annuity Insurance Company (“PLAIC”), a wholly owned subsidiary of the Company, entered into reinsurance agreements (the “Reinsurance Agreements”) and related ancillary documents (including administrative services agreements and transition services agreements) providing for the reinsurance and administration of the Life Business. 

Pursuant to the Reinsurance Agreements, Liberty ceded to the Company and PLAIC the insurance policies related to the Life Business on a 100% coinsurance basis. The aggregate ceding commission for the reinsurance of the Life Business was $422.9 million. All policies issued in states other than New York were ceded to the Company under a reinsurance agreement between Liberty and the Company, and all policies issued in New York were ceded to PLAIC under a reinsurance agreement between Liberty and PLAIC. The aggregate statutory reserves of Liberty ceded to the Company and PLAIC as of the closing of the Transaction were approximately $13.3 billion, which amount was based on initial estimates and is subject to adjustment following the Closing.  Pursuant to the terms of the Reinsurance Agreements, each of the Company and PLAIC are required to maintain assets in trust for the benefit of Liberty to secure their respective obligations to Liberty under the Reinsurance Agreements. The trust accounts were initially funded by each of the Company and PLAIC principally with the investment assets that were received from Liberty. Additionally, the Company and PLAIC have each agreed to provide, on behalf of Liberty, administration and policyholder servicing of the Life Business reinsured by it pursuant to administrative services agreements between Liberty and each of the Company and PLAIC.

CRITICAL ACCOUNTING POLICIES

Our accounting policies require the use of judgments relating to a variety of assumptions and estimates, including, but not limited to expectations of current and future mortality, morbidity, persistency, expenses, and interest rates, as well as expectations around the valuations of securities. Because of the inherent uncertainty when using the assumptions and estimates, the effect of certain accounting policies under different conditions or assumptions could be materially different from those reported in the consolidated condensed financial statements. For a complete listing of our critical accounting policies, refer to our Annual Report on Form 10-K for the year ended December 31, 2017.

RESULTS OF OPERATIONS

Our 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 our 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 guaranteed living withdrawal benefits ("GLWB") embedded derivatives exclusive of the portion attributable to the economic cost of the GLWB,

• actual GLWB incurred claims, and

• the amortization of deferred acquisition costs ("DAC"), value of business acquired ("VOBA"), and certain policy liabilities that is impacted by the exclusion of these items.

After-tax adjusted operating income (loss) is derived from pre-tax adjusted operating income (loss) with the inclusion of income tax expense or benefits associated with pre-tax adjusted operating income. Income tax expense or benefits is allocated to the items excluded from pre-tax adjusted operating income (loss) at the statutory federal income tax rate for the associated period. For periods ending on and prior to December 31, 2017 a rate of 35% was used. Beginning in 2018, a statutory federal income tax rate of 21% will be used to allocate income tax expense or benefits to items excluded from pre-tax adjusted operating income (loss). Income tax expense or benefits allocated to after-tax adjusted operating income (loss) can vary period to period based on changes in our effective income tax rate.

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. Our belief is 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 policy liabilities net of associated policy assets, while DAC/VOBA and goodwill are shown in the segments to which they are attributable.

We periodically review and update as appropriate our key assumptions used to measure certain balances related to insurance products, including future mortality, expenses, lapses, premium persistency, benefit utilization, investment yields, interest rates, and separate account fund returns. Changes to these assumptions result in adjustments which increase or decrease DAC and VOBA amortization and/or benefits and expenses. The periodic review and updating of assumptions is referred to as “unlocking.” When referring to unlocking the reference is to changes in all balance sheet components associated with these assumption changes.

For The Three Months Ended March 31, 2018 as compared to The Three Months Ended March 31, 2017

Net income for the three months ended March 31, 2018 included a $44.1 million, or 40.4%, decrease in pre-tax adjusted operating income. The decrease consisted of a $35.2 million decrease in the Life Marketing segment, a $11.9 million decrease in the Annuities segment, and a $4.4 million decrease in the Corporate and Other segment. These decreases were partially offset by a $1.9 million increase in the Acquisitions segment, a $5.2 million decrease in the Stable Value Products segment, and a $0.3 million increase in the Asset Protection segment.

Net realized losses on investments and derivatives for the three months ended March 31, 2018, was $43.2 million. These losses were primarily due to net losses of $2.1 million related to the Modco trading portfolio and the associated embedded derivative, impairment losses on available-for-sale securities of $3.6 million, and net losses of $62.6 million related to the variable annuity contracts. Partially offsetting these losses were net gains on derivatives with PLC of $11.5 million, net gains from sales of securities of $2.8 million, and net gains of $15.3 million related to IUL and FIA contracts.

59

• Life Marketing segment pre-tax adjusted operating loss was $15.2 million for the three months ended March 31, 2018, representing a decrease of $35.2 million from the three months ended March 31, 2017. The decrease was primarily due to an increase in claims and lower traditional life net premiums, offset by an increase in universal life net policy fees. Life claims were approximately $33.4 million higher for the three months ended March 31, 2018 when compared to the three months ended March 31, 2017.

• Acquisitions segment pre-tax adjusted operating income was $55.5 million for the three months ended March 31, 2018, an increase of $1.9 million as compared to the three months ended March 31, 2017, primarily due to a decrease in overall benefit expense and favorable adjustments to reinsurance premiums.

• Annuities segment pre-tax adjusted operating income was $30.2 million for the three months ended March 31, 2018, as compared to $42.1 million for the three months ended March 31, 2017, a decrease of $11.9 million, or 28.3%. This variance was primarily the result of unfavorable unlocking, an unfavorable change in single premium immediate annuities (“SPIA”) mortality, and higher non-deferred expenses, partially offset by increased interest spreads and growth in the variable annuities ("VA") fee income. Segment results were negatively impacted by $5.2 million of unfavorable unlocking for the three months ended March 31, 2018, as compared to $1.6 million of favorable unlocking for the three months ended March 31, 2017.

• Stable Value segment pre-tax adjusted operating income was $29.1 million and increased $5.2 million, or 21.7%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The increase in adjusted operating earnings primarily resulted from higher average account values. Participating mortgage income for the three months ended March 31, 2018, was $6.9 million as compared to $6.8 million for the three months ended March 31, 2017. The adjusted operating spread, which excludes participating income, decreased by four basis points for the three months ended March 31, 2018, from the prior year, due primarily to an increase in credited interest.

• Asset Protection segment pre-tax adjusted operating income was $4.3 million, representing an increase of $0.3 million, or 8.8%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. Service contract earnings increased $0.9 million primarily due to favorable loss ratios and higher investment income. Credit insurance earnings decreased $0.5 million primarily due to lower volume. Earnings from the GAP product line decreased $0.1 million.

• The Corporate and Other segment pre-tax adjusted operating loss was $38.8 million for the three months ended March 31, 2018, as compared to a pre-tax adjusted operating loss of $34.4 million for the three months ended March 31, 2017. The higher operating loss was primarily due to an increase in corporate overhead expenses, partly offset by an increase in investment income due to higher invested asset balances and improved yields.

For The Three Months Ended March 31, 2018, as compared to The Three Months Ended March 31, 2017

Pre-tax adjusted operating income (loss)

Pre-tax adjusted operating loss was $15.2 million for the three months ended March 31, 2018, representing a decrease of $35.2 million from the three months ended March 31, 2017. The decrease was primarily due to an increase in claims and lower traditional life net premiums, offset by an increase in universal life net policy fees. Life claims were approximately $33.4 million higher for the three months ended March 31, 2018 when compared to three months ended March 31, 2017.

Operating revenues

Total operating revenues for the three months ended March 31, 2018, increased $4.4 million, or 1.1%, as compared to the three months ended March 31, 2017. This increase was driven by higher policy fees.

Net premiums and policy fees

Net premiums and policy fees increased by $5.1 million, or 2.0%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, due to an increase in policy fees associated with continued growth in universal life business. Offsetting this was a decrease in traditional life premiums.

Net investment income

Net investment income in the segment decreased $1.2 million, or 0.9%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, due to lower traditional life investment income of $1.9 million, offset by higher universal life investment income of $0.7 million.

Other income

Other income remained consistent for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017.

Benefits and settlement expenses

Benefits and settlement expenses increased by $29.1 million, or 8.8%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, due to an increase in claims, partly offset by a decrease in traditional life reserves. For the three months ended March 31, 2018, universal life unlocking increased policy benefits and settlement expenses $3.8 million, as compared to a decrease of $0.9 million for the three months ended March 31, 2017.

Amortization of DAC/VOBA

DAC/VOBA amortization increased $1.2 million, or 4.1%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, due to higher VOBA amortization in the universal life block, offset by lower VOBA amortization in the traditional blocks. For the three months ended March 31, 2018, universal life unlocking increased amortization $4.2 million, as compared to an increase of $0.3 million for the three months ended March 31, 2017.

Other operating expenses

Other operating expenses increased $9.3 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. This increase was driven by higher general and administrative expenses, commissions and taxes, licenses and fees, along with a decrease in ceding allowances.

Sales

Sales for the segment decreased $1.0 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to lower sales in the universal life block, mostly offset by higher traditional life sales. The change between products was due to a shift in sales focus from a product within the universal life block to a new term life product.

Reinsurance

Currently, the Life Marketing segment reinsures significant amounts of its life insurance in-force. Pursuant to the underlying reinsurance contracts, reinsurers pay allowances to the segment as a percentage of both first year and renewal premiums. Reinsurance allowances represent the amount the reinsurer is willing to pay for reimbursement of acquisition costs incurred by the direct writer of the business. A portion of reinsurance allowances received is deferred as part of DAC and a portion is recognized immediately as a reduction of other operating expenses. As the non-deferred portion of allowances reduces operating expenses in the period received, these amounts represent a net increase to adjusted operating income during that period.

Reinsurance allowances do not affect the methodology used to amortize DAC or the period over which such DAC is amortized. However, they do affect the amounts recognized as DAC amortization. DAC on universal life-type, limited-payment long duration, and investment contracts business is amortized based on the estimated gross profits of the policies in-force. Reinsurance allowances are considered in the determination of estimated gross profits, and therefore, impact DAC amortization on these lines of business. Deferred reinsurance allowances on level term business are recorded as ceded DAC, which is amortized over estimated ceded premiums of the policies in-force. Thus, deferred reinsurance allowances may impact DAC amortization. A more detailed discussion of the components of reinsurance can be found in the Reinsurance section of Note 2, Summary of

(1)  Other operating expenses ceded per the income statement are equal to reinsurance allowances recognized after capitalization.

The table above does not reflect the impact of reinsurance on our net investment income. By ceding business to the assuming companies, we forgo investment income on the reserves ceded. Conversely, the assuming companies will receive investment income on the reserves assumed, which will increase the assuming companies’ profitability on the business that we cede. The net investment income impact to us and the assuming companies has not been quantified. The impact of including foregone investment income would be to substantially reduce the favorable net impact of reinsurance reflected above. We estimate that the impact of foregone investment income would be to reduce the net impact of reinsurance presented in the table above by 305% to 390%. The Life Marketing segment’s reinsurance programs do not materially impact the “other income” line of our income statement.

As shown above, reinsurance had a favorable impact on the Life Marketing segment’s operating income for the periods presented above. The impact of reinsurance is largely due to our quota share coinsurance program in place prior to mid-2005. Under that program, generally 90% of the segment’s traditional new business was ceded to reinsurers. Since mid-2005, a much smaller percentage of overall term business has been ceded due to a change in reinsurance strategy on traditional business. In addition, since 2012, a much smaller percentage of the segment’s new universal life business has been ceded. As a result of that change, the relative impact of reinsurance on the Life Marketing segment’s overall results is expected to decrease over time. While the significance of reinsurance is expected to decline over time, the overall impact of reinsurance for a given period may fluctuate due to variations in mortality, and unlocking of balances.

64

For The Three Months Ended March 31, 2018, as compared to The Three Months Ended March 31, 2017

The higher ceded premium and policy fees for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, was caused primarily by higher ceded traditional life premiums of $22.7 million and higher universal life policy fees of $6.4 million.

Ceded benefits and settlement expenses were higher for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, due to higher ceded claims. Traditional ceded benefits and settlement expenses increased $58.4 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to higher ceded reserves and claims. Universal life ceded benefits increased $7.2 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to higher ceded claims, partially offset by lower ceded reserves. Ceded universal life claims were $32.8 million higher and ceded traditional life claims were $39.1 million higher for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017.

Ceded amortization of DAC and VOBA decreased slightly for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017.

Ceded other operating expenses reflect the impact of reinsurance allowances net of amounts deferred.

For The Three Months Ended March 31, 2018, as compared to The Three Months Ended March 31, 2017

Pre-tax adjusted operating income

Pre-tax adjusted operating income was $55.5 million for the three months ended March 31, 2018, an increase of $1.9 million as compared to the three months ended March 31, 2017, primarily due to a decrease in overall benefit expense and favorable adjustments to reinsurance premiums.

Operating revenues

Net premiums and policy fees decreased $2.1 million, or 1.0%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to expected runoff of the in-force blocks of business. Net investment income decreased $7.4 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017 due to expected runoff of the in-force blocks of business.

Total benefits and expenses

Total benefits and expenses decreased $12.2 million, or 3.6%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The decrease was primarily due to the expected runoff of the in-force blocks of business, partly offset by unfavorable mortality experience and higher amortization of VOBA.

Reinsurance

The Acquisitions segment currently reinsures portions of both its life and annuity in-force. The cost of reinsurance to the segment is reflected in the chart shown below. A more detailed discussion of the components of reinsurance can be found in the Reinsurance section of Note 2, Summary of Significant Accounting Policies of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

NET IMPACT OF REINSURANCE(1)	$	14,394		$	(2,801	)
(1)  Assumes no investment income on reinsurance. Foregone investment income would substantially reduce the favorable impact of reinsurance.

The segment’s reinsurance programs do not materially impact the other income line of the income statement. In addition, net investment income generally has no direct impact on reinsurance cost. However, by ceding business to the assuming companies, we forgo investment income on the reserves ceded to the assuming companies. Conversely, the assuming companies will receive investment income on the reserves assumed which will increase the assuming companies’ profitability on business assumed from the Company. For business ceded under modified coinsurance arrangements, the amount of investment income attributable to the assuming company is included as part of the overall change in policy reserves and, as such, is reflected in benefit and settlement expenses. The net investment income impact to us and the assuming companies has not been quantified as it is not fully reflected in our consolidated financial statements.

The net impact of reinsurance was more favorable by $17.2 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to higher ceded claims. For the three months ended March 31, 2018, ceded revenues decreased by $2.6 million, while ceded benefits and expenses increased by $14.6 million primarily due to higher claims.

For The Three Months Ended March 31, 2018, as compared to The Three Months Ended March 31, 2017

Pre-tax adjusted operating income

Pre-tax adjusted operating income was $30.2 million for the three months ended March 31, 2018, as compared to $42.1 million for the three months ended March 31, 2017, a decrease of $11.9 million, or 28.3%. This variance was primarily the result of unfavorable unlocking, an unfavorable change in SPIA mortality, and higher non-deferred expenses, partially offset by increased interest spreads and growth in the VA fee income. Segment results were negatively impacted by $5.2 million of unfavorable unlocking for the three months ended March 31, 2018, as compared to $1.6 million of favorable unlocking for the three months ended March 31, 2017.

Operating revenues

Segment operating revenues increased $3.8 million, or 2.9%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to higher investment income and higher policy fees and other income from the VA line of business. The higher investment income related to growth in account values. Average fixed account balances increased 5.2% and average variable account balances increased 2.3% for the three months ended March 31, 2018 as compared to the three months ended March 31, 2017.

Benefits and settlement expenses

Benefits and settlement expenses increased $6.3 million, or 12.4%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. This increase was primarily the result of unfavorable SPIA mortality, higher credited interest, and an unfavorable change in guaranteed benefit reserves. Included in benefits and settlement expenses was $0.1 million of unfavorable unlocking for the three months ended March 31, 2018, as compared to $0.1 million of favorable unlocking for the three months ended March 31, 2017.

Amortization of DAC and VOBA

DAC and VOBA amortization unfavorably changed by $6.9 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The unfavorable change was primarily due to unfavorable unlocking. DAC and VOBA unlocking for the three months ended March 31, 2018, was $5.1 million unfavorable as compared to $1.4 million favorable for the three months ended March 31, 2017.

Other operating expenses

Other operating expenses increased $2.4 million, or 6.8%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. Increases in non-deferred acquisition expense and commission expenses were partially offset by lower non-deferred maintenance and overhead expense.

Sales

Total sales increased $197.4 million, or 63.6%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. Sales of variable annuities decreased $24.7 million, or 21.7%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to disruptions in the broader market driven by regulatory rule changes and the relative competitiveness of our product within the market. Sales of fixed annuities increased by $222.0 million, or 112.9%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to an increase in single premium deferred annuities (“SPDA”) sales.

Reinsurance

During the year ended December 31, 2013, the Annuity segment began reinsuring certain risks associated with the GLWB and GMDB riders to Shades Creek Captive Insurance Company (“Shades Creek”), a direct wholly owned subsidiary of PLC. The cost of reinsurance to the segment is reflected in the chart shown below. The impact of the Shades Creek reinsurance arrangement for the three month period ending March 31, 2013, was eliminated in consolidation. Prior to April 1, 2013, we paid as a dividend all of Shades Creek’s outstanding common stock to its parent, PLC. A more detailed discussion of the components of reinsurance

Net premiums and policy fees

Net premiums and policy fees decreased $3.0 million, or 5.9%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. GAP and credit insurance premiums decreased $2.2 million and $1.1 million, respectively, as a result of lower sales. Service contract premiums increased $0.2 million.

Other income

Other income remained consistent for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017.

Benefits and settlement expenses

Benefits and settlement expenses decreased $2.6 million, or 8.3%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. GAP and credit insurance claims decreased $0.1 million and $0.2 million, respectively, primarily due to lower volume. Service contract claims decreased $2.3 million due to lower loss ratios.

Amortization of DAC and VOBA and Other operating expenses

Amortization of DAC and VOBA increased $10.9 million and other operating expenses decreased $11.4 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The changes were due to the impact of an accounting change implemented in conjunction with the adoption of ASU No. 2014-09.

Sales

Total segment sales decreased $18.0 million, or 14.4%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. GAP sales decreased $15.8 million due to discontinuing the relationship with a significant distribution partner. Service contract sales decreased $1.4 million due to lower volume resulting from previous price increases. Credit insurance sales decreased $0.9 million due to decreasing demand for the product.

Reinsurance

The majority of the Asset Protection segment’s reinsurance activity relates to the cession of single premium credit life and credit accident and health insurance, vehicle service contracts, and guaranteed asset protection insurance to producer affiliated reinsurance companies (“PARCs”). These arrangements are coinsurance contracts ceding the business on a first dollar quota share basis at 100% to limit our exposure and allow the PARCs to share in the underwriting income of the product. Reinsurance contracts do not relieve us from our obligations to our policyholders. A more detailed discussion of the components of reinsurance can be found in the Reinsurance section of Note 2, Summary of Significant Accounting Policies to our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

For The Three Months Ended March 31, 2018, as compared to The Three Months Ended March 31, 2017

Reinsurance premiums ceded increased $0.2 million, or 0.6%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The increase was primarily due to an increase in ceded service contract premiums, mostly offset by a decrease in ceded GAP premiums.

Benefits and settlement expenses ceded increased $1.4 million, or 8.6%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The increase was primarily due to higher ceded losses in all product lines.

Amortization of DAC and VOBA ceded increased $0.3 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, as the result of ceded activity in all product lines. Other operating expenses ceded decreased $0.2 million for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017.

Net investment income has no direct impact on reinsurance cost. However, by ceding business to the assuming companies, we forgo investment income on the reserves ceded. Conversely, the assuming companies will receive investment income on the reserves assumed which generally will increase the assuming companies’ profitability on business we cede. The net investment income impact to us and the assuming companies has not been quantified as it is not reflected in our consolidated financial statements.

Pre-tax adjusted operating income (loss)

Pre-tax adjusted operating loss was $38.8 million for the three months ended March 31, 2018, as compared to a pre-tax adjusted operating loss of $34.4 million for the three months ended March 31, 2017. The higher operating loss was primarily due to an increase in corporate overhead expense, partly offset by an increase in investment income due to higher invested asset balances and improved yields.

Operating revenues

Net investment income for the segment increased $5.4 million or 21% for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017. The increase was primarily due to an increase in invested asset balances and yields.

Total benefits and expenses

Total benefits and expenses increased $9.7 million, or 15%, for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to increases in interest expense and corporate overhead expenses.

CONSOLIDATED INVESTMENTS

As of March 31, 2018, our investment portfolio was approximately $52.9 billion. The types of assets in which we may invest are influenced by various state insurance laws which prescribe qualified investment assets. Within the parameters of these laws, we invest in assets giving consideration to such factors as liquidity and capital needs, investment quality, investment return, matching of assets and liabilities, and the overall composition of the investment portfolio by asset type and credit exposure. We do not have material exposure to financial guarantee insurance companies with respect to our investment portfolio.

Within our fixed maturity investments, we maintain portfolios classified as “available-for-sale”, “trading”, and “held-to-maturity”. We purchase our available-for-sale investments with the intent to hold to maturity by purchasing investments that match future cash flow needs. However, we may sell any of our available-for-sale and trading investments to maintain proper matching of assets and liabilities. Accordingly, we classified $37.2 billion, or 87.6%, of our fixed maturities as “available-for-sale” as of March 31, 2018. These securities are carried at fair value on our consolidated condensed balance sheets. Changes in fair value for our available-for-sale portfolio, net of tax and the related impact on certain insurance assets and liabilities are recorded directly to shareowner’s equity. Declines in fair value that are other-than-temporary are recorded as realized losses in the consolidated condensed statements of income, net of any applicable non-credit component of the loss, which is recorded as an adjustment to other comprehensive income (loss).

Trading securities are carried at fair value and changes in fair value are recorded on the income statement as they occur. Our trading portfolio accounted for $2.6 billion, or 6.1%, of our fixed maturities and $70.5 million of short-term investments as of March 31, 2018. Changes in fair value on the Modco trading portfolios, including gains and losses from sales, are passed to third party reinsurers through the contractual terms of the related reinsurance arrangements. Partially offsetting these amounts are corresponding changes in the fair value of the embedded derivative associated with the underlying reinsurance arrangement.

Fixed maturities with respect to which we have both the positive intent and ability to hold to maturity are classified as “held-to-maturity”. We classified $2.7 billion, or 6.3%, of our fixed maturities as “held-to-maturity” as of March 31, 2018. These securities are carried at amortized cost on our consolidated condensed balance sheets.

Fair values for private, non-traded securities are determined as follows: 1) we obtain estimates from independent pricing services and 2) we estimate fair value based upon a comparison to quoted issues of the same issuer or issues of other issuers with similar terms and risk characteristics. We analyze the independent pricing services valuation methodologies and related inputs, including an assessment of the observability of market inputs. Upon obtaining this information related to fair value, management makes a determination as to the appropriate valuation amount. For more information about the fair values of our investments please refer to Note 5, Fair Value of Financial Instruments, to the financial statements.

(1) Our "not rated" securities are $2.7 billion or 6.3% of our fixed maturity investments, of held-to-maturity securities issued by affiliates of the Company which are considered variable interest entities ("VIE's") and are discussed in Note 4, Investment Operations, to the consolidated condensed financial statements. We are not the primary beneficiary of these entities and thus these securities are not eliminated in consolidation. These securities are collateralized by non-recourse funding obligations issued by captive insurance companies that are wholly owned subsidiaries of the Company.

We use various Nationally Recognized Statistical Rating Organizations’ (“NRSRO”) ratings when classifying securities by quality ratings. When the various NRSRO ratings are not consistent for a security, we use the second-highest convention in assigning the rating. When there are no such published ratings, we assign a rating based on the statutory accounting rating system if such ratings are available.

A portion of our bond portfolio is invested in residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”), and other asset-backed securities (collectively referred to as asset-backed securities or “ABS”). ABS are securities that are backed by a pool of assets. These holdings as of March 31, 2018, were approximately $6.0 billion. Mortgage-backed securities (“MBS”) are constructed from pools of mortgages and may have cash flow volatility as a result of changes in the rate at which prepayments of principal occur with respect to the underlying loans. Excluding limitations on access to lending and other extraordinary economic conditions, prepayments of principal on the underlying loans can be expected to accelerate with decreases in market interest rates and diminish with increases in interest rates.

Mortgage Loans

We invest a portion of our investment portfolio in commercial mortgage loans. As of March 31, 2018, our mortgage loan holdings were approximately $6.8 billion. We have specialized in making loans on either credit-oriented commercial properties or credit-anchored strip shopping centers and apartments. Our underwriting procedures relative to our commercial loan portfolio are based, in our view, on a conservative and disciplined approach. We concentrate 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). We believe that these asset types tend to weather economic downturns better than other commercial asset classes in which we have chosen not to participate. We believe this disciplined approach has helped to maintain a relatively low delinquency and foreclosure rate throughout our history. The majority of our mortgage loans portfolio was underwritten and funded by us. From time to time, we may acquire loans in conjunction with an acquisition.

Our commercial mortgage loans are stated at unpaid principal balance, adjusted for any unamortized premium or discount, and net of valuation allowances. Interest income is accrued on the principal amount of the loan based on the loan’s contractual interest rate. Amortization of premiums and discounts is recorded using the effective yield method. Interest income, amortization of premiums and discounts, and prepayment fees are reported in net investment income.

83

Certain of the mortgage loans have call options that occur within the next 12 years. However, if interest rates were to significantly increase, we may be unable to exercise the call options on our existing mortgage loans commensurate with the significantly increased market rates. As of March 31, 2018, assuming the loans are called at their next call dates, approximately $143.6 million of principal would become due for the remainder of 2018, $873.1 million in 2019 through 2023, $105.0 million in 2024 through 2028, and $2.0 million thereafter.

We offer a type of commercial mortgage loan under which we 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 March 31, 2018 and December 31, 2017, approximately $672.1 million and $669.3 million, respectively, of our 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 months ended March 31, 2018 and 2017, we recognized $7.3 million and $6.8 million, respectively, of participating mortgage loan income.

We record mortgage loans net of an allowance for credit losses. This allowance is calculated through analysis of specific loans that have indicators of potential impairment based on current information and events. As of March 31, 2018 and December 31, 2017, there were no allowances for mortgage loan credit losses. While our mortgage loans do not have quoted market values, as of March 31, 2018, we estimated the fair value of our mortgage loans to be $6.6 billion (using an internal fair value model which calculates the value of most loans by using the loan's discounted cash flows to the loan's call or maturity date), which was approximately 2.92% less than the amortized cost, less any related loan loss reserve.

At the time of origination, our mortgage lending criteria targets that the loan-to-value ratio on each mortgage is 75% or less. We target projected rental payments from credit anchors (i.e., excluding rental payments from smaller local tenants) of 70% of the property’s projected operating expenses and debt service.

As of March 31, 2018, none of the Company's invested assets consisted of nonperforming mortgage loans, restructured mortgage loans, or mortgage loans that were foreclosed and were converted to real estate properties. For all mortgage loans, the impact of troubled debt restructurings is reflected in our investment balance and in the allowance for mortgage loan credit losses. During the three months ended March 31, 2018, we recognized no troubled debt restructurings and we did not identify any loans whose principal was permanently impaired.

Our 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 March 31, 2018, the Company did not have mortgage loans not subject to a pooling and servicing agreement that were nonperforming mortgage loans, restructured, or mortgage loans that were foreclosed and were converted to real estate properties. We did not foreclose on any nonperforming loans not subject to a pooling and servicing agreement during the three months ended March 31, 2018.

As of March 31, 2018, none of the loans subject to a pooling and servicing agreement were nonperforming or restructured. We did not foreclose on any nonperforming loans subject to a pooling and servicing agreement during the three months ended March 31, 2018.

We do not expect these investments to adversely affect our liquidity or ability to maintain proper matching of assets and liabilities.

It is our 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 our 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.

Unrealized Gains and Losses — Available-for-Sale Securities

The information presented below relates to investments at a certain point in time and is not necessarily indicative of the status of the portfolio at any time after March 31, 2018, the balance sheet date. Information about unrealized gains and losses is subject to rapidly changing conditions, including volatility of financial markets and changes in interest rates. Management considers a number of factors in determining if an unrealized loss is other-than-temporary, including the expected cash to be collected and the intent, likelihood, and/or ability to hold the security until recovery. Consistent with our long-standing practice, we do not utilize a “bright line test” to determine other-than-temporary impairments. On a quarterly basis, we perform an analysis on every security with an unrealized loss to determine if an other-than-temporary impairment has occurred. This analysis includes reviewing several metrics including collateral, expected cash flows, ratings, and liquidity. Furthermore, since the timing of recognizing realized gains and losses is largely based on management’s decisions as to the timing and selection of investments to be sold, the tables and information provided below should be considered within the context of the overall unrealized gain/(loss) position of the portfolio. We had an overall net unrealized loss of $1.1 billion, prior to tax and the related impact of certain insurance assets and liabilities offsets, as of March 31, 2018, and an overall net unrealized gain of $32.5 million as of December 31, 2017.

As of March 31, 2018, the Barclays Investment Grade Index was priced at 107 bps versus a 10 year average of 173 bps. Similarly, the Barclays High Yield Index was priced at 370 bps versus a 10 year average of 642 bps. As of March 31, 2018, the five, ten, and thirty-year U.S. Treasury obligations were trading at levels of 2.6%, 2.7%, and 3.0%, as compared to 10 year averages of 1.7%, 2.6%, and 3.4%, respectively.

As of March 31, 2018, 93.4% of the unrealized loss was associated with securities that were rated investment grade. We have examined the performance of the underlying collateral and cash flows and expect that our investments will continue to perform in accordance with their contractual terms. Factors such as credit enhancements within the deal structures and the underlying collateral performance/characteristics support the recoverability of the investments. Based on the factors discussed, we do not consider these unrealized loss positions to be other-than-temporary. However, from time to time, we may sell securities in the ordinary course of managing our portfolio to meet diversification, credit quality, yield enhancement, asset/liability management, and liquidity requirements.

Expectations that investments in mortgage-backed and asset-backed securities will continue to perform in accordance with their contractual terms are based on assumptions that a market participant would use in determining the current fair value. It is reasonably possible that the underlying collateral of these investments will perform worse than current market expectations and that such an event may lead to adverse changes in the cash flows on our holdings of these types of securities. This could lead to potential future write-downs within our portfolio of mortgage-backed and asset-backed securities. Expectations that our investments in corporate securities and/or debt obligations will continue to perform in accordance with their contractual terms are based on evidence gathered through our normal credit surveillance process. Although we do not anticipate such events, it is reasonably possible that issuers of our investments in corporate securities will perform worse than current expectations. Such events may lead us to recognize potential future write-downs within our portfolio of corporate securities. It is also possible that such unanticipated events would lead us to dispose of those certain holdings and recognize the effects of any such market movements in our financial statements.

As of March 31, 2018, there were estimated gross unrealized losses of $3.2 million related to our mortgage-backed securities collateralized by Alt-A mortgage loans. Gross unrealized losses in our securities collateralized by Alt-A residential mortgage loans as of March 31, 2018, were primarily the result of continued widening spreads, representing marketplace uncertainty arising from higher defaults in Alt-A residential mortgage loans and rating agency downgrades of securities collateralized by Alt-A residential mortgage loans.

As of March 31, 2018, we held a total of 2,428 positions that were in an unrealized loss position. Included in that amount were 94 positions of below investment grade securities with a fair value of $789.9 million that were in an unrealized loss position. Total unrealized losses related to below investment grade securities were $96.1 million, $70.3 million of which had been in an

87

unrealized loss position for more than twelve months. Below investment grade securities in an unrealized loss position were 1.5% of invested assets.

As of March 31, 2018, securities in an unrealized loss position that were rated as below investment grade represented 2.6% of the total fair value and 6.6% of the total unrealized loss. We have the ability and intent to hold these securities to maturity. After a review of each security and its expected cash flows, we believe the decline in market value to be temporary.

Determining whether a decline in the current fair value of invested assets is an other-than-temporary decline in value is both objective and subjective, and can involve a variety of assumptions and estimates, particularly for investments that are not actively traded in established markets. We review our positions on a monthly basis for possible credit concerns and review our current exposure, credit enhancement, and delinquency experience.

Management considers a number of factors when determining the impairment status of individual securities. These include the economic condition of various industry segments and geographic locations and other areas of identified risks. Since it is possible for the impairment of one investment to affect other investments, we engage in ongoing risk management to safeguard against and limit any further risk to our investment portfolio. Special attention is given to correlative risks within specific industries, related parties, and business markets.

For certain securitized financial assets with contractual cash flows, including RMBS, CMBS, and other asset-backed securities (collectively referred to as asset-backed securities or “ABS”), GAAP requires us to periodically update our best estimate of cash flows over the life of the security. If the fair value of a securitized financial asset is less than its cost or amortized cost and there has been a decrease in the present value of the expected cash flows since the last revised estimate, considering both timing and amount, an other-than-temporary impairment charge is recognized. Estimating future cash flows is a quantitative and qualitative process that incorporates information received from third party sources along with certain internal assumptions and judgments regarding the future performance of the underlying collateral. Projections of expected future cash flows may change based upon new information regarding the performance of the underlying collateral. In addition, we consider our intent and ability to retain a temporarily depressed security until recovery.

Securities in an unrealized loss position are reviewed at least quarterly to determine if an other-than-temporary impairment is present based on certain quantitative and qualitative factors. We consider a number of factors in determining whether the impairment is other-than-temporary. These include, but are not limited to: 1) actions taken by rating agencies, 2) default by the issuer, 3) the significance of the decline, 4) an assessment of our intent to sell the security (including a more likely than not assessment of whether we will be required to sell the security) before recovering the security’s amortized cost, 5) the time period during which the decline has occurred, 6) an economic analysis of the issuer’s industry, and 7) the financial strength, liquidity, and recoverability of the issuer. Management performs a security-by-security review each quarter in evaluating the need for any other-than-temporary impairments. Although no set formula is used in this process, the investment performance, collateral position, and continued viability of the issuer are significant measures considered, along with an analysis regarding our expectations for recovery of the security’s entire amortized cost basis through the receipt of future cash flows. Based on our analysis, for the three months ended March 31, 2018, we recognized approximately $3.6 million of credit related impairments on investment securities in an unrealized loss position that were other-than-temporarily impaired resulting in a charge to earnings.

There are certain risks and uncertainties associated with determining whether declines in fair values are other-than-temporary. These include significant changes in general economic conditions and business markets, trends in certain industry segments, interest rate fluctuations, rating agency actions, changes in significant accounting estimates and assumptions, commission of fraud, and legislative actions. We continuously monitor these factors as they relate to the investment portfolio in determining the status of each investment.

We have deposits with certain financial institutions which exceed federally insured limits. We have reviewed the creditworthiness of these financial institutions and believe that there is minimal risk of a material loss.

The chart shown below includes our non-sovereign fair value exposures in these countries as of March 31, 2018. As of March 31, 2018, we had no unfunded exposure and had no direct sovereign exposure.

Realized gains and losses on investments reflect portfolio management activities designed to maintain proper matching of assets and liabilities and to enhance long-term investment portfolio performance. The change in net realized investment gains (losses), excluding impairments and Modco trading portfolio activity during the three months ended March 31, 2018, primarily reflects the normal operation of our asset/liability program within the context of the changing interest rate and spread environment, as well as tax planning strategies designed to utilize capital loss carryforwards.

Realized losses are comprised of other-than-temporary impairments and actual sales of investments. These other-than-temporary impairments resulted from our analysis of circumstances and our belief that credit events, loss severity, changes in

91

credit enhancement, and/or other adverse conditions of the respective issuers have caused, or will lead to, a deficiency in the contractual cash flows related to these investments. These other-than-temporary impairments are presented in the chart below:

As previously discussed, management considers several factors when determining other-than-temporary impairments. Although we purchase securities with the intent to hold them until maturity, we may change our position as a result of a change in circumstances. Any such decision is consistent with our classification of all but a specific portion of our investment portfolio as available-for-sale. For the three months ended March 31, 2018, we sold securities in an unrealized loss position with a fair value of $57.0 million. For such securities, the proceeds, realized loss, and total time period that the security had been in an unrealized loss position are presented in the table below:

	Proceeds		% Proceeds		Realized Loss			% Realized Loss
	(Dollars In Thousands)

For the three months ended March 31, 2018, we sold securities in an unrealized loss position with a fair value (proceeds) of $57.0 million. The losses realized on the sale of these securities were $5.3 million. We made the decision to exit these holdings in conjunction with our overall asset liability management process.

For the three months ended March 31, 2018, we sold securities in an unrealized gain position with a fair value of $142.1 million. The gains realized on the sale of these securities were $8.0 million.

The $3.1 million of other realized gains recognized for the three months ended March 31, 2018, included $3.4 million of realized gains associated with our mortgage loan portfolio, partnership gains of $0.1 million, fixed asset losses of $0.1 million, and real estate losses of $0.2 million, respectively.

For the three months ended March 31, 2018, net losses of $84.7 million , primarily related to changes in fair value on our Modco trading portfolios, were included in realized gains and losses. Of the $84.7 million for the three months ended March 31, 2018, approximately $2.5 million of losses were realized through the sale of certain securities, which will be returned to us from our reinsurance partners over time through the reinsurance settlement process for this block of business. The Modco embedded derivative associated with the trading portfolios had realized pre-tax gains of $82.7 million during the three months ended March 31, 2018. The gains during the three months ended March 31, 2018, were due to the credit spreads widening and treasury yields increasing.

Realized investment gains and losses related to derivatives represent changes in their fair value during the period and termination gains/(losses) on those derivatives that were closed during the period.

We use various derivative instruments to manage risks related to certain life insurance and annuity products. We can use these derivatives as economic hedges against risks inherent in the products. These risks have a direct impact on the cost of these products and are correlated with the equity markets, interest rates, foreign currency levels, and overall volatility. The hedged risks are recorded through the recognition of embedded derivatives associated with the products. These products include the GLWB rider associated with the variable annuity, fixed indexed annuity products as well as indexed universal life products. During the three months ended March 31, 2018, we experienced net realized losses of $62.6 million on derivatives related to VA contracts. These net losses on derivatives related to VA contracts were affected by capital market impacts, changes in our non-performance risk, and variations in actual sub-account fund performance from the indices included in our hedging program during the three months ended March 31, 2018.

The Funds Withheld derivative associated with Shades Creek had pre-tax realized losses of $8.0 million for the three months ended March 31, 2018.

92

Certain of our subsidiaries have derivatives with PLC. These derivatives consist of an interest support agreement, two YRT premium support agreements, and three portfolio maintenance agreements with PLC. We recognized gains of $10.4 million related to the interest support agreement for the three months ended March 31, 2018. We recognized gains of $0.8 million related to the YRT premium support agreements for the three months ended March 31, 2018.

We entered into two separate portfolio maintenance agreements in October 2012 and one portfolio maintenance agreement in January 2016. We recognized gains of $0.4 million for the three months ended March 31, 2018.

We also use various swaps and other types of derivatives to mitigate risk related to other exposures. For the three months ended March 31, 2018, these contracts generated immaterial losses.

LIQUIDITY AND CAPITAL RESOURCES

The Holding Company

Overview

Our primary sources of funding are from our insurance operations and revenues from investments. These sources of cash support our operations and are used to pay dividends to PLC.

The states in which we and our insurance subsidiaries are domiciled impose certain restrictions on the ability to pay dividends. These restrictions are based in part on the prior year’s statutory income and/or surplus.

Debt and other capital resources

Our primary sources of capital are from retained income from our insurance operations and capital infusions from our parent, PLC. Additionally, we have access to the Credit Facility discussed below.

We have the ability to borrow under a Credit Facility arrangement on an unsecured basis up to an aggregate principal amount of $1.0 billion. We have 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. We are not aware of any non-compliance with the financial debt covenants of the Credit Facility as of March 31, 2018. PLC had an outstanding balance of $325.0 million bearing interest at a rate of LIBOR plus 1.00% as of March 31, 2018.

Liquidity

Liquidity refers to a company’s ability to generate adequate amounts of cash to meet its needs. We meet our liquidity requirements primarily through positive cash flows from our operating subsidiaries. Primary sources of cash from the operating subsidiaries are premiums, deposits for policyholder accounts, investment sales and maturities, and investment income. Primary uses of cash include benefit payments, withdrawals from policyholder accounts, investment purchases, policy acquisition costs, interest payments, and other operating expenses. We believe that we have sufficient liquidity to fund our cash needs under normal operating scenarios.

In the event of significant unanticipated cash requirements beyond our normal liquidity needs, we have additional sources of liquidity available depending on market conditions and the amount and timing of the liquidity need. These additional sources of liquidity include cash flows from operations, the sale of liquid assets, accessing our credit facility, and other sources described herein. Our decision to sell investment assets could be impacted by accounting rules, including rules relating to the likelihood of a requirement to sell securities before recovery of our cost basis. Under stressful market and economic conditions, liquidity may broadly deteriorate, which could negatively impact our ability to sell investment assets. If we require on short notice significant amounts of cash in excess of normal requirements, we may have difficulty selling investment assets in a timely manner, be forced to sell them for less than we otherwise would have been able to realize, or both.

Our liquidity requirements primarily relate to the liabilities associated with our various insurance and investment products, operating expenses, and income taxes. Liabilities arising from insurance and investment products include the payment of policyholder benefits, as well as cash payments in connection with policy surrenders and withdrawals, policy loans, and obligations to redeem funding agreements.

We maintain investment strategies intended to provide adequate funds to pay benefits and expected surrenders, withdrawals, loans, and redemption obligations without forced sales of investments. In addition, our insurance subsidiaries hold highly liquid, high-quality short-term investment securities and other liquid investment grade fixed maturity securities to fund our expected operating expenses, surrenders, and withdrawals. We were committed as of March 31, 2018 to fund mortgage loans in the amount of $699.6 million.

Our positive cash flows from operations are used to fund an investment portfolio that provides for future benefit payments. We employ a formal asset/liability program to manage the cash flows of our investment portfolio relative to our long-term benefit obligations. As of March 31, 2018, we held cash and short-term investments of approximately $610.5 million.

The following chart includes the cash flows provided by or used in operating, investing, and financing activities for the following periods:

	For The Three Months Ended March 31,
	2018			2017
	(Dollars In Thousands)
Net cash (used in) provided by operating activities	$	(48,243	)	$	43,124
Net cash provided by (used in) investing activities	14,873			(370,398		)
Net cash provided by financing activities	115,135			368,294
Total	$	81,765		$	41,020

For The Three Months Ended March 31, 2018 as compared to the Three Months Ended March 31, 2017

Net cash (used in) provided by operating activities - Cash flows from operating activities are affected by the timing of premiums received, investment income, and benefits and expenses paid. Principal sources of cash inflows from operating activities include sales of our products and services as well as income from investments. We typically generate positive cash flows from operating activities, as premiums and policy fees collected from our insurance and investment products exceed benefit payments and redemptions, and we invest the excess. Due to the nature of our business and the fact that many of the products we sell produce financing and investing cash flows it is important to consider cash flows generated by investing and financing activities in conjunction with those generated by operating activities.

Net cash provided by (used in) investing activities - Changes in cash from investing activities primarily related to our investment portfolio.

Net cash provided by financing activities - Changes in cash from financing activities included $238.8 million of outflows from secured financing liabilities for the three months ended March 31, 2018, as compared to the $29.5 million of inflows for the three months ended March 31, 2017 and $372.3 million of inflows of investment product and universal life net activity as compared to $349.8 million in the prior year. Net repayment of non-recourse funding obligations equaled $18.3 million during the three months ended March 31, 2018 as compared to net repayments of $11.0 million during the three months ended March 31, 2017.

Through our subsidiaries, we are members of the FHLB of Cincinnati and the FHLB of New York. FHLB advances provide an attractive funding source for short-term borrowing and for the sale of funding agreements. Membership in the FHLB requires that we purchase FHLB capital stock based on a minimum requirement and a percentage of the dollar amount of advances outstanding. Our borrowing capacity is determined by criteria established by each respective bank. In addition, our obligations under the advances must be collateralized. We maintain control over any such pledged assets, including the right of substitution. As of March 31, 2018, we had $595.8 million of funding agreement-related advances and accrued interest outstanding under the FHLB program.

While we anticipate that the cash flows of our operating subsidiaries will be sufficient to meet our investment commitments and operating cash needs in a normal credit market environment, we recognize that investment commitments scheduled to be funded may, from time to time, exceed the funds then available. Therefore, we have established repurchase agreement programs for certain of our insurance subsidiaries to provide liquidity when needed. We expect that the rate received on its investments will equal or exceed its borrowing rate. Under this program, we may, from time to time, sell an investment security at a specific price and agree to repurchase that security at another specified price at a later date. These borrowings are typically for a term less than 90 days. The market value of securities to be repurchased is monitored and collateral levels are adjusted where appropriate to protect the counterparty against credit exposure. Cash received is invested in fixed maturity securities, and the agreements provided for net settlement in the event of default or on termination of the agreements. As of March 31, 2018, the fair value of securities pledged under the repurchase program was $753.6 million and the repurchase obligation of $665.0 million was included in our consolidated condensed balance sheets (at an average borrowing rate of 173 basis points). During the three months ended March 31, 2018, the maximum balance outstanding at any one point in time related to these programs was $885.0 million. The average daily balance was $808.0 million (at an average borrowing rate of 149 basis points) during the three months ended March 31, 2018. As of December 31, 2017, the fair value of securities pledged under the repurchase program was $1,006.6 million and the repurchase obligation of $885.0 million was included in our consolidated condensed balance sheets (at an average borrowing rate of 142 basis points). During 2017, the maximum balance outstanding at any one point in time related to these programs was $988.5 million. The average daily balance was $624.7 million (at an average borrowing rate of 101 basis points) during the year ended December 31, 2017.

We participate 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. We require 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 March 31, 2018, securities with a market value of $107.0 million were loaned under this program. As collateral for the loaned securities, we receive short-term investments, which are recorded in “short-term investments” with a corresponding liability recorded in “other liabilities” to account for its obligation to return the collateral. As of March 31, 2018, the fair value of the collateral related to this program was $113.9 million and we have an obligation to return $113.9 million of collateral to the securities borrowers.

Statutory Capital

A life insurance company’s statutory capital is computed according to rules prescribed by the NAIC, as modified by state law. Generally speaking, other states in which a company does business defer to the interpretation of the domiciliary state with respect to NAIC rules, unless inconsistent with the other state’s regulations. Statutory accounting rules are different from GAAP and are intended to reflect a more conservative view, for example, requiring immediate expensing of policy acquisition costs. The NAIC’s risk-based capital requirements require insurance companies to calculate and report information under a risk-based capital formula. The achievement of long-term growth will require growth in the statutory capital of our insurance subsidiaries. The subsidiaries may secure additional statutory capital through various sources, such as retained statutory earnings or our equity contributions. In general, dividends up to specified levels are considered ordinary and may be paid without prior approval of the insurance commissioner of the state of domicile. Dividends in larger amounts are considered extraordinary and are subject to affirmative prior approval by such commissioner. The maximum amount that would qualify as an ordinary dividend from our insurance subsidiaries in 2018 is approximately $175.1million.

State insurance regulators and the NAIC have adopted risk-based capital (“RBC”) requirements for life insurance companies to evaluate the adequacy of statutory capital and surplus in relation to investment and insurance risks. The requirements provide a means of measuring the minimum amount of statutory surplus appropriate for an insurance company to support its overall business operations based on its size and risk profile. A company’s risk-based statutory surplus is calculated by applying factors and performing calculations relating to various asset, premium, claim, expense, and reserve items. Regulators can then measure the adequacy of a company’s statutory surplus by comparing it to RBC. We manage our capital consumption by using the ratio of our total adjusted capital, as defined by the insurance regulators, to our company action level RBC (known as the RBC ratio), also as defined by insurance regulators.

Statutory reserves established for VA contracts are sensitive to changes in the equity markets and are affected by the level of account values relative to the level of any guarantees and product design. As a result, the relationship between reserve changes and equity market performance may be non-linear during any given reporting period. Market conditions greatly influence the capital required due to their impact on the valuation of reserves and derivative investments mitigating the risk in these reserves. Risk mitigation activities may result in material and sometimes counterintuitive impacts on statutory surplus and RBC ratio. Notably, as changes in these market and non-market factors occur, both our potential obligation and the related statutory reserves and/or required capital can vary at a non-linear rate.

Our statutory surplus is impacted by credit spreads as a result of accounting for the assets and liabilities on our fixed MVA annuities. Statutory separate account assets supporting the fixed MVA annuities are recorded at fair value. In determining the statutory reserve for the fixed MVA annuities, we are required to use current crediting rates based on U.S. Treasuries. In many capital market scenarios, current crediting rates based on U.S. Treasuries are highly correlated with market rates implicit in the fair value of statutory separate account assets. As a result, the change in the statutory reserve from period to period will likely substantially offset the change in the fair value of the statutory separate account assets. However, in periods of volatile credit markets, actual credit spreads on investment assets may increase or decrease sharply for certain sub-sectors of the overall credit market, resulting in statutory separate account asset market value gains or losses. As actual credit spreads are not fully reflected in current crediting rates based on U.S. Treasuries, the calculation of statutory reserves will not substantially offset the change in fair value of the statutory separate account assets resulting in a change in statutory surplus.

We cede material amounts of insurance and transfer related assets to other insurance companies through reinsurance. However, notwithstanding the transfer of related assets, we remain liable with respect to ceded insurance should any reinsurer fail to meet the obligations that it assumed. We evaluate the financial condition of our reinsurers and monitor the associated concentration of credit risk. For the three months ended March 31, 2018, we ceded premiums to third party reinsurers amounting to $345.6 million. In addition, we had receivables from reinsurers amounting to $4.8 billion as of March 31, 2018. We review reinsurance receivable amounts for collectability and establish bad debt reserves if deemed appropriate.

Captive Reinsurance Companies

The Company and our life insurance subsidiaries are subject to a regulation entitled “Valuation of Life Insurance Policies Model Regulation,” commonly known as “Regulation XXX,” and a supporting guideline entitled “The Application of the Valuation of Life Insurance Policies Model Regulation,” commonly known as “Guideline AXXX.” The regulation and supporting guideline require insurers to establish statutory reserves for term and universal life insurance policies with long-term premium guarantees that are consistent with the statutory reserves required for other individual life insurance policies with similar guarantees. Many market participants believe that these levels of reserves are non-economic. We use captive reinsurance companies to implement reinsurance and capital management actions to satisfy these reserve requirements by financing the non-economic reserves either through the issuance of non-recourse funding obligations by the captives or obtaining Letters of Credit from third-party financial institutions.

Our captive reinsurance companies assume business from affiliates only. Our captives are capitalized to a level we believe is sufficient to support the contractual risks and other general obligations of the respective captive entity. All of our captive reinsurance companies are wholly owned subsidiaries and are located domestically. The captive insurance companies are subject to regulations in the state of domicile.

The National Association of Insurance Commissioners (“NAIC”), through various committees, subgroups and dedicated task forces, is reviewing the use of captives and special purpose vehicles used to transfer insurance risk in relation to existing state laws and regulations, and several committees have adopted or exposed for comment white papers and reports that, if or when implemented, could impose additional requirements on the use of captives and other reinsurers. The Financial Condition (E) Committee of the NAIC established a Variable Annuity Issues Working Group to examine company use of variable annuity

95

captives. The Committee has proposed changes in the regulation of variable annuities and variable annuity captives could adversely affect our future financial condition and results of operations.

The NAIC has adopted Actuarial Guideline XLVIII ("AG48") and the substantially similar "Term and Universal Life Insurance Reserve Financing Model Regulation" (the "Reserve Model") which establish national standards for new reserve financing arrangements for term life insurance and universal life insurance with secondary guarantees. AG48 and the Reserve Model govern collateral requirements for captive reinsurance arrangements. In order to obtain reserve credit, AG48 and the Reserve Model require a minimum level of funds, consisting of primary and other securities, to be held by or on behalf of ceding insurers as security under each captive life reinsurance treaty. As a result of AG48 and the Reserve Model, the implementation of new captive structures in the future may be less capital efficient, lead to lower product returns and/or increased product pricing or result in reduced sales of certain products. In some circumstances, AG48 and the Reserve Model could impact the Company’s ability to engage in certain reinsurance transactions with non-affiliates.

We also use a captive reinsurance company to reinsure risks associated with GLWB and GMDB riders which helps us to manage those risks on an economic basis. In an effort to mitigate the equity market risks relative to our RBC ratio, we reinsure these risks to Shades Creek Captive Insurance Company (“Shades Creek”). The purpose of Shades Creek is to reduce the volatility in RBC due to non-economic variables included within the RBC calculation.

During 2012, PLC entered into an intercompany capital support agreement with Shades Creek. The agreement provides through a guarantee that PLC will contribute assets or purchase surplus notes (or cause an affiliate or third party to contribute assets or purchase surplus notes) in amounts necessary for Shades Creek’s regulatory capital levels to equal or exceed minimum thresholds as defined by the agreement. As of March 31, 2018, Shades Creek maintained capital levels in excess of the required minimum thresholds. The maximum potential future payment amount which could be required under the capital support agreement will be dependent on numerous factors, including the performance of equity markets, the level of interest rates, performance of associated hedges, and related policyholder behavior.

Ratings

Various Nationally Recognized Statistical Rating Organizations (“rating organizations”) review the financial performance and condition of insurers, including us and our insurance subsidiaries, and publish their financial strength ratings as indicators of an insurer’s ability to meet policyholder and contract holder obligations. These ratings are important to maintaining public confidence in an insurer’s products, its ability to market its products and its competitive position. The following table summarizes the current financial strength ratings of our significant member companies from the major independent rating organizations:

			Standard &
Ratings	A.M. Best	Fitch	Poor’s	Moody’s
Insurance company financial strength rating:
Protective Life Insurance Company	A+	A+	AA-	A1
West Coast Life Insurance Company	A+	A+	AA-	A1
Protective Life and Annuity Insurance Company	A+	A+	AA-	—
Protective Property & Casualty Insurance Company	A	—	—	—
MONY Life Insurance Company	A+	A+	A+	A1

 Our ratings are subject to review and change by the rating organizations at any time and without notice. A downgrade or other negative action by a rating organization with respect to the financial strength ratings of us and our insurance subsidiaries could adversely affect sales, relationships with distributors, the level of policy surrenders and withdrawals, competitive position in the marketplace, and the cost or availability of reinsurance. The rating agencies may take various actions, positive or negative, with respect to the debt and financial strength ratings of PLC and its subsidiaries, including as a result of PLC’s status as a subsidiary of Dai-ichi Life.

LIABILITIES

Many of our products contain surrender charges and other features that are designed to reward persistency and penalize the early withdrawal of funds. Certain stable value and annuity contracts have market-value adjustments that protect us against investment losses if interest rates are higher at the time of surrender than at the time of issue.

As of March 31, 2018, we had policy liabilities and accruals of approximately $31.5 billion. Our interest-sensitive life insurance policies have a weighted average minimum credited interest rate of approximately 3.47%.

96

Contractual Obligations

We enter into various obligations to third parties in the ordinary course of our operations. However, we do not believe that our cash flow requirements can be assessed solely based upon an analysis of these obligations. The most significant factors affecting our future cash flows are our ability to earn and collect cash from our customers, and the cash flows arising from our investment program. Future cash outflows, whether they are contractual obligations or not, will also vary based upon our future needs. Although some outflows are fixed, others depend on future events. Examples of fixed obligations include our obligations to pay principal and interest on fixed-rate borrowings. Examples of obligations that will vary include obligations to pay interest on variable-rate borrowings and insurance liabilities that depend on future interest rates, market performance, or surrender provisions. Many of our obligations are linked to cash-generating contracts. In addition, our operations involve significant expenditures that are not based upon contractual obligations. These include expenditures for income taxes and payroll.

As of March 31, 2018, we carried a $6.4 million liability for uncertain tax positions. These amounts are not included in the long-term contractual obligations table because of the difficulty in making reasonably reliable estimates of the occurrence or timing of cash settlements with the respective taxing authorities.

The table below sets forth future maturities of our contractual obligations:

			Payments due by period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years

(1) Non-recourse funding obligations include all undiscounted principal amounts owed and expected future interest payments due over the term of the notes. Of the total undiscounted cash flows, $1.7 billion relates to the Golden Gate V transaction. These cash outflows are matched and predominantly offset by the cash inflows Golden Gate V receives from notes issued by a nonconsolidated variable interest entity. Additionally, $2.7 billion relates to the Golden Gate transaction that occurred in Q1 2016. These cash outflows are matched and predominantly offset by the cash inflows Golden Gate receives from notes issued by a nonconsolidated entity and third parties. The remaining amounts are associated with the Golden Gate II notes held by third parties as well as certain obligations assumed with the acquisition of MONY Life Insurance Company.
(2) Anticipated stable value products cash flows including interest.
(3) Includes all lease payments required under operating lease agreements.
(4) The lease payments shown assume we exercise our option to purchase the building at the end of the lease term. Additionally, the payments due by the periods above were computed based on the terms of the renegotiated lease agreement, which was entered in December 2013.
(5) Represents secured borrowings and accrued interest as part of our repurchase program as well as liabilities associated with securities lending transactions.
(6) Estimated contractual policyholder obligations are based on mortality, morbidity, and lapse assumptions comparable to our historical experience, modified for recent observed trends. These obligations are based on current balance sheet values and include expected interest crediting, but do not incorporate an expectation of future market growth, or future deposits. Due to the significance of the assumptions used, the amounts presented could materially differ from actual results. As variable separate account obligations are legally insulated from general account obligations, the variable separate account obligations will be fully funded by cash flows from variable separate account assets. We expect to fully fund the general account obligations from cash flows from general account investments.

OFF-BALANCE SHEET ARRANGEMENTS

We have entered into operating leases that do not result in an obligation being recorded on the balance sheet. Refer to Note 11, Commitments and Contingencies, of the consolidated condensed financial statements for more information.

MARKET RISK EXPOSURES

Our financial position and earnings are subject to various market risks including changes in interest rates, the yield curve, spreads between risk-adjusted and risk-free interest rates, foreign currency rates, used vehicle prices, and equity price risks and issuer defaults. We analyze and manage the risks arising from market exposures of financial instruments, as well as other risks, through an integrated asset/liability management process. Our asset/liability management programs and procedures involve the monitoring of asset and liability durations for various product lines; cash flow testing under various interest rate scenarios; and the continuous rebalancing of assets and liabilities with respect to yield, credit and market risk, and cash flow characteristics. These programs also incorporate the use of derivative financial instruments primarily to reduce our exposure to interest rate risk,

97

inflation risk, currency exchange risk, volatility risk, and equity market risk. See Note 6, Derivative Financial Instruments, to the consolidated financial statements included in this report for additional information on our financial instruments.

The primary focus of our asset/liability program is the management of interest rate risk within the insurance operations. This includes monitoring the duration of both investments and insurance liabilities to maintain an appropriate balance between risk and profitability for each product category, and for us as a whole. It is our policy to maintain asset and liability durations within one year of one another, although, from time to time, a broader interval may be allowed.

We are exposed to credit risk within our investment portfolio and through derivative counterparties. Credit risk relates to the uncertainty of an obligor’s continued ability to make timely payments in accordance with the contractual terms of the instrument or contract. We manage credit risk through established investment policies which attempt to address quality of obligors and counterparties, credit concentration limits, diversification requirements, and acceptable risk levels under expected and stressed scenarios. Derivative counterparty credit risk is measured as the amount owed to us, net of collateral held, based upon current market conditions. In addition, we periodically assess exposure related to potential payment obligations between us and our counterparties. We minimize the credit risk in derivative financial instruments by entering into transactions with high quality counterparties, (A-rated or higher at the time we enter into the contract), and we maintain credit support annexes with certain of those counterparties.

We utilize 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 our analysis of data from financial simulation models and other internal and industry sources, and are then incorporated into our risk management program.

Derivative instruments expose us to credit and market risk and could result in material changes from period to period. We attempt to minimize our credit risk by entering into transactions with highly rated counterparties. We manage the market risk by establishing and monitoring limits as to the types and degrees of risk that may be undertaken. We monitor our use of derivatives in connection with our overall asset/liability management programs and risk management strategies. In addition, all derivative programs are monitored by our risk management department.

Derivative instruments that are used as part of our interest rate risk management strategy include interest rate swaps, interest rate futures, interest rate caps, and interest rate swaptions.

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.

We may use the following types of derivative contracts to mitigate our exposure to certain guaranteed benefits related to VA 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 our subsidiaries have derivatives with PLC. These derivatives consist of an interest support agreement, YRT premium support arrangements, and portfolio maintenance agreements with PLC.

We have 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.

We believe that our asset/liability management programs and procedures and certain product features provide protection against the effects of changes in interest rates under various scenarios. Additionally, we believe our asset/liability management programs and procedures provide sufficient liquidity to enable us to fulfill our obligation to pay benefits under our various insurance and deposit contracts. However, our asset/liability management programs and procedures incorporate assumptions about the relationship between short-term and long-term interest rates (i.e., the slope of the yield curve), relationships between risk-adjusted and risk-free interest rates, market liquidity, spread movements, implied volatility, policyholder behavior, and other factors, and the effectiveness of our asset/liability management programs and procedures may be negatively affected whenever actual results differ from those assumptions.

In the ordinary course of our commercial mortgage lending operations, we may commit to provide a mortgage loan before the property to be mortgaged has been built or acquired. The mortgage loan commitment is a contractual obligation to fund a mortgage loan when called upon by the borrower. The commitment is not recognized in our financial statements until the

98

commitment is actually funded. The mortgage loan commitment contains terms, including the rate of interest, which may be different than prevailing interest rates. As of March 31, 2018, we had outstanding mortgage loan commitments of $699.6 million at an average rate of 4.2%.

Impact of Continued Low Interest Rate Environment

Significant changes in interest rates expose us to the risk of not realizing anticipated spreads between the interest rate earned on investments and the interest rate credited to in-force policies and contracts. In addition, certain of our insurance and investment products guarantee a minimum guaranteed interest rate (“MGIR”). In periods of prolonged low interest rates, the interest spread earned may be negatively impacted to the extent our ability to reduce policyholder crediting rates is limited by the guaranteed minimum credited interest rates. Additionally, those policies without account values may exhibit lower profitability in periods of prolonged low interest rates due to reduced investment income.

The tables below present account values by range of current minimum guaranteed interest rates and current crediting rates for our universal life and deferred fixed annuity products as of March 31, 2018 and December 31, 2017:

We are active in mitigating the impact of a continued low interest rate environment through product design, as well as adjusting crediting rates on current in-force policies and contracts. We also manage interest rate and reinvestment risks through our asset/liability management process. Our asset/liability management programs and procedures involve the monitoring of asset and liability durations; cash flow testing under various interest rate scenarios; and the regular rebalancing of assets and liabilities with respect to yield, credit and market risk, and cash flow characteristics. These programs also incorporate the use of derivative financial instruments primarily to reduce our exposure to interest rate risk, inflation risk, currency exchange risk, volatility risk, and equity market risk.

IMPACT OF INFLATION

Inflation increases the need for life insurance. Many policyholders who once had adequate insurance programs may increase their life insurance coverage to provide the same relative financial benefit and protection. Higher interest rates may result in higher sales of certain of our investment products.

The higher interest rates that have traditionally accompanied inflation could also affect our operations. Policy loans increase as policy loan interest rates become relatively more attractive. As interest rates increase, disintermediation of stable value and annuity account balances and individual life policy cash values may increase. The market value of our fixed-rate, long-term investments may decrease, we may be unable to implement fully the interest rate reset and call provisions of our mortgage loans, and our ability to make attractive mortgage loans, including participating mortgage loans, may decrease. In addition, participating mortgage loan income may decrease. The difference between the interest rate earned on investments and the interest rate credited to life insurance and investment products may also be adversely affected by rising interest rates. During the periods covered by this report, we believe inflation has not had a material impact on our business.

Item 4.Controls and Procedures

(a)    Disclosure controls and procedures

In order to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission is recorded, processed, summarized, and reported on a timely basis, the Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), except as otherwise noted below. Based on their evaluation as of the end of the period covered by this Form 10-Q, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective. It should be noted that any system of controls, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of any control system is based in part upon certain judgments, including the costs and benefits of controls and the likelihood of future events. Because of these and other inherent limitations of control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within the Company have been detected.

(b)Changes in internal control over financial reporting

There were no changes in the Company’s internal control over financial reporting during the three months ended March 31, 2018, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II

Item 1A.  Risk Factors

The operating results of companies in the insurance industry have historically been subject to significant fluctuations. The factors which could affect the Company’s future results include, but are not limited to, general economic conditions and known trends and uncertainties. In addition to other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A, Risk Factors, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, which could materially affect the Company’s business, financial condition, or future results of operations which are discussed more fully below.

Risks Related to the Financial Environment

The Company may be required to establish a valuation allowance against its deferred tax assets, which could have a material adverse effect on the Company's results of operations, financial condition, and capital position.

Deferred tax assets are attributable to certain differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets represent future savings of taxes that would otherwise be paid in cash. In general, the realization of the deferred tax assets is dependent upon the generation of sufficient future ordinary and capital taxable income. If it is determined that a certain deferred tax asset cannot be realized, then a deferred tax valuation allowance must be established, with a corresponding charge to either adjusted operating income or other comprehensive income (depending on the nature of the deferred tax asset).

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 its material deferred tax assets net of any existing valuation allowance. The Company has recognized valuation allowances of $5.0 million and $5.0 million as of March 31, 2018 and December 31, 2017, respectively, related to state operating loss and interest expense carryforwards which are more likely than not to expire unutilized. If future events differ from the Company's current forecasts, an additional valuation allowance may need to be established, which could have a material adverse effect on the Company's results of operations, financial condition, or capital position.

The Company could be adversely affected by an inability to access FHLB lending.

The Company and certain of its subsidiaries are members of the Federal Home Loan Bank (the “FHLB”) of Cincinnati and the FHLB of New York. Membership provides the Company and these certain subsidiaries with access to FHLB financial services, including advances that provide an attractive funding source for short-term borrowing and for the sale of funding agreements. The extent to which these services are available could be impacted by legislative or regulatory action at the state or federal level. It is unclear at this time whether or to what extent additional or new legislation or regulatory action regarding continued access to FHLB financial services will be enacted or adopted. Any developments that limit access to FHLB financial services could have a material adverse effect on the Company.

The amount of statutory capital or risk-based capital that the Company has and the amount of statutory capital or risk-based capital that it must hold to maintain its financial strength and credit ratings and meet other requirements can vary significantly from time to time and such amounts are sensitive to a number of factors outside of the Company’s control.

Beyond its own business, the Company also conducts business through licensed company subsidiaries. Insurance regulators have established regulations that provide minimum capitalization requirements based on risk-based capital formulas for life and property and casualty companies. The risk-based capital formula for life insurance companies establishes capital

101

requirements relating to insurance, business, asset, interest rate, and certain other risks. The risk-based capital formula for property and casualty companies establishes capital requirements relating to asset, credit, underwriting, and certain other risks.

In any particular year, statutory surplus amounts and risk-based capital ratios may increase or decrease depending on a variety of factors, including, but not limited to, the amount of statutory income or losses generated by the Company and its insurance subsidiaries (which itself is sensitive to equity market and credit market conditions), the amount of additional capital which it and its insurance subsidiaries must hold to support business growth, changes in the Company’s statutory reserve requirements, the Company’s ability to secure capital market solutions to provide statutory reserve relief, changes in equity market levels, the value of certain fixed-income and equity securities in its investment portfolio, the credit ratings of investments held in its portfolio, including those issued by, or explicitly or implicitly guaranteed by, a government, the value of certain derivative instruments, changes in interest rates, foreign currency exchange rates or tax rates, credit market volatility, changes in consumer behavior, and changes to the National Association of Insurance Commissioners (the "NAIC") risk-based capital formula. Most of these factors are outside of the Company’s control.

The NAIC is currently considering several changes to the formula used to calculate risk-based capital. One of the changes under consideration relates to the corporate tax rate. Previously, the NAIC risk-based capital formula used a tax factor that generally assumed a 35% corporate tax rate. In 2018, the maximum corporate tax rate was set at 21%. The NAIC's Capital Adequacy Task Force and its working groups have stated their intention to update the risk-based capital formula to reflect the lower corporate tax rate. Another contemplated change would update the factors used to calculate required capital for bonds. While the extent and timing of either such change is unknown, both changes would likely increase required capital upon becoming effective, which in turn would decrease the statutory risk-based capital ratios of U.S. life insurance companies, including the Company and its subsidiaries. Ultimately, the changes contemplated by the NAIC could have an individually or cumulatively material adverse effect on the Company’s financial condition and/or results of operations.

The Company’s financial strength and credit ratings are significantly influenced by the statutory surplus amounts and risk-based capital ratios of its insurance company subsidiaries. Rating agencies may implement changes to their internal models that have the effect of increasing or decreasing the amount of statutory capital the Company must hold in order to maintain its current ratings. In addition, rating agencies may downgrade the investments held in the Company’s portfolio, which could result in a reduction of the Company’s capital and surplus and/or its risk-based capital ratio.

In scenarios of equity market declines, the amount of additional statutory reserves or risk-based capital the Company is required to hold for its variable product guarantees may increase at a rate greater than the rate of change of the markets. Increases in reserves or risk-based capital could result in a reduction to the Company’s capital, surplus, and/or risk-based capital ratio. Also, in environments where there is not a correlative relationship between interest rates and spreads, the Company’s market value adjusted annuity product can have a material adverse effect on the Company’s statutory surplus position.

Industry and Regulatory Related Risks

The Company may be subject to regulations of, or regulations influenced by, international regulatory authorities or initiatives.

The NAIC and the Company’s state regulators may be influenced by the initiatives of international regulatory bodies, and those initiatives may not translate readily into the legal system under which U.S. insurers must operate. There is increasing pressure to conform to international standards due to the globalization of the business of insurance and the most recent financial crisis. In addition to developments at the NAIC and in the United States, the Financial Stability Board (“FSB”), consisting of representatives of national financial authorities of the G20 nations, and the G20 have issued a series of proposals intended to produce significant changes in how financial companies, particularly companies that are members of large and complex financial groups, should be regulated.

The International Association of Insurance Supervisors (“IAIS”), at the direction of the FSB, has published an evolving methodology for identifying “global systemically important insurers” (“G-SIIs”) and high-level policy measures that will apply to G-SIIs. The FSB, working with national authorities and the IAIS, has designated nine insurance groups as G-SIIs. The IAIS is working on the policy measures which include higher capital requirements and enhanced supervision. Although neither the Company nor Dai-ichi Life has been designated as a G-SII, the list of designated insurers will be updated periodically by the FSB. It is possible that the greater size and reach of the combined group as a result of the Company becoming a subsidiary of Dai-ichi Life, or a change in the methodologies or their application, could lead to the combined group’s designation as a G-SII.

The IAIS is also in the process of developing a common framework for the supervision of internationally active insurance groups (“IAIGs”). The framework, which is currently under discussion, may include a global capital measurement standard for insurance groups deemed to be IAIGs that could exceed the sum of state or other local capital requirements. In addition, the IAIS is developing a model framework for the supervision of IAIGs that contemplates “group wide supervision” across national boundaries and legal entities, which could require each IAIG to conduct its own risk and solvency assessment to monitor and manage its overall solvency. It is likely that, as a result of the Merger, the combined group will be deemed an IAIG, in which case it may be subject to supervision requirements and capital measurement standards beyond those applicable to any competitors who are not designated as an IAIG.

PLC’s sole stockholder, Dai-ichi Life, is also subject to regulation by the Japanese Financial Services Authority (“JFSA”). Under applicable laws and regulations, Dai-ichi Life is required to provide notice to or obtain the consent of the JFSA prior to taking certain actions or engaging in certain transactions, either directly or indirectly through its subsidiaries, including the Company and its consolidated subsidiaries, which could limit the ability of the Company to engage in certain transactions or business initiatives.

102

While it is not yet known how or the extent to which the Company will be impacted by these regulations, the Company may experience increased costs of compliance, increased disclosure, less flexibility in capital management, and more burdensome regulation and capital requirements for specific lines of business. In addition, such regulations could impact the business of the Company and its reserve and capital requirements, financial condition or results of operations.

The Company’s use of captive reinsurance companies to finance statutory reserves related to its term and universal life products and to reduce volatility affecting its variable annuity products may be limited or adversely affected by regulatory action, pronouncements and interpretations.

The Company currently uses affiliated captive reinsurance companies in various structures to finance certain statutory reserves based on a regulation entitled “Valuation of Life Insurance Policies Model Regulation,” commonly known as “Regulation XXX,” and a supporting guideline entitled “The Application of the Valuation of Life Insurance Policies Model Regulation,” commonly known as “Guideline AXXX,” which are associated with term life insurance and universal life insurance with secondary guarantees, respectively, as well as to reduce the volatility in statutory risk-based capital associated with certain guaranteed minimum withdrawal and death benefit riders associated with certain of the Company’s variable annuity products.

The NAIC has adopted Actuarial Guideline XLVIII ("AG48") and the substantially similar "Term and Universal Life Insurance Reserve Financing Model Regulation" (the "Reserve Model") which establish national standards for new reserve financing arrangements for term life insurance and universal life insurance with secondary guarantees. AG48 and the Reserve Model govern collateral requirements for captive reinsurance arrangements. In order to obtain reserve credit, AG48 and the Reserve Model require a minimum level of funds, consisting of primary and other securities, to be held by or on behalf of ceding insurers as security under each captive life reinsurance treaty. As a result of AG48 and the Reserve Model, the implementation of new captive structures in the future may be less capital efficient, lead to lower product returns and/or increased product pricing, or result in reduced sales of certain products. In some circumstances, AG48 and the Reserve Model could impact the Company’s ability to engage in certain reinsurance transactions with non-affiliates.

The Financial Condition (E) Committee of the NAIC established a Variable Annuity Issues Working Group ("VAIWG") in 2015 to oversee the NAIC’s efforts to study and address regulatory issues resulting in variable annuity captive reinsurance transactions. The VAIWG developed a Framework for Change (the “Framework”) which was adopted in 2015. The Framework suggests numerous changes to current NAIC rules and regulations that are intended to decrease incentives for insurers to establish variable annuities captives, which changes could potentially be applied to both in-force and new business. The Framework proposes that various NAIC groups consider and adopt recommended changes to current rules and regulations (with a likely effective date in 2020) and that, upon adoption, domestic regulators request that insurers ceding business to variable annuity captives recapture such business and dissolve such captives. If adopted, changes in the regulation of variable annuities and variable annuity captives could adversely affect our future financial condition and results of operations.

The NAIC adopted revisions to the Part A Laws and Regulations Preamble (the "Preamble") of the NAIC Financial Regulation Standards and Accreditation Program that includes within the definition of “multi-state insurer” certain insurer-owned captives and special purpose vehicles that are single-state licensed but assume reinsurance from cedants operating in multiple states. The revised definition subjects certain captives, including XXX/AXXX captives, variable annuity and long-term care captives, to all of the accreditation standards applicable to other traditional multi-state insurers, including standards related to capital and surplus requirements, risk-based capital requirements, investment laws and credit for reinsurance laws. Although we do not expect the revised definition to affect our existing life insurance captives (or our ability to engage in life insurance captive transactions in the future), such application will likely prevent us from engaging in variable annuity captive transactions on the same or a similar basis as in the past and, if applied retroactively, would likely cause us to recapture business from and unwind our existing variable annuity captive (“VA Captive”).

While the recapture of business from our existing VA Captive, caused either by actions of the VAIWG or the effect of the Preamble, would not have a material adverse effect on the Company given current market conditions, in the future the Company could experience fluctuations in its risk-based capital ratio due to market volatility if it were prohibited from engaging in similar transactions or required to unwind its existing VA Captive, which could adversely affect our future financial condition and results of operations.

Any regulatory action or change in interpretation that materially adversely affects the Company’s use or materially increases the Company’s cost of using captives or reinsurers for the affected business, either retroactively or prospectively, could have a material adverse impact on the Company’s financial condition or results of operations. If the Company were required to discontinue its use of captives for intercompany reinsurance transactions on a retroactive basis, adverse impacts would include early termination fees payable to third party finance providers with respect to certain structures, diminished capital position and higher cost of capital. Additionally, finding alternative means to support policy liabilities efficiently is an unknown factor that would be dependent, in part, on future market conditions and the Company’s ability to obtain required regulatory approvals. On a prospective basis, discontinuation of the use of captives could impact the types, amounts and pricing of products offered by the Company and its insurance subsidiaries.

103

Laws, regulations and initiatives related to unreported deaths and unclaimed property and death benefits may result in operational burdens, fines, unexpected payments or escheatments.

Since 2012, various states have enacted laws that require life insurers to search for unreported deaths. The National Conference of Insurance Legislators ("NCOIL") has adopted the Model Unclaimed Life Insurance Benefits Act (the "Unclaimed Benefits Act") and legislation or regulations have been enacted in numerous states that are similar to the Unclaimed Benefits Act, although each state's version differs in some respects. The Unclaimed Benefits Act, if adopted by any state, imposes new requirements on insurers to periodically compare their life insurance and annuity contracts and retained asset accounts against the U.S. Social Security Administration's Death Master File or similar databases (a "Death Database"), investigate any potential matches to confirm the death and determine whether benefits are due, and to attempt to locate the beneficiaries of any benefits that are due or, if no beneficiary can be located, escheat the benefit to the state as unclaimed property. Other states in which the Company does business may also consider adopting legislation similar to the Unclaimed Benefits Act. The Company cannot predict whether such legislation will be proposed or enacted in additional states.

The Uniform Laws Commission has adopted revisions to the Uniform Unclaimed Property Act in a manner likely to impact state unclaimed property laws and requirements, though it is not clear at this time to what extent or whether requirements will conflict with otherwise imposed search requirements. Other life insurance industry associations and regulatory associations are also considering these matters. Certain states have amended or may amend their unclaimed property laws to require insurers to compare in-force and certain terminated life insurance policies, annuity contracts, and retained asset accounts against a Death Database, to investigate potential matches to determine whether the named insured is deceased, to attempt to locate and pay beneficiaries any unclaimed benefits required to be paid, and, if no beneficiary can be located, to escheat policy benefits to the appropriate state as unclaimed property. The enactment of such unclaimed property laws may require the Company to incur significant expenses, including benefits with respect to terminated policies for which no reserves are currently held and unanticipated operational expenses. Any of the foregoing could have a material adverse effect on the Company's financial condition and results of operations.

A number of state treasury departments and administrators of unclaimed property have audited life insurance companies for compliance with unclaimed property laws. The focus of the audits has been to determine whether there have been maturities of policies or contracts, or policies that have exceeded limiting age with respect to which death benefits or other payments under the policies should be treated as unclaimed property that should be escheated to the state. In addition, the audits have sought to identify unreported deaths of insureds. There is no clear basis in previously existing law for treating an unreported death as giving rise to a policy benefit that would be subject to unclaimed property procedures. A number of life insurers, however, have entered into resolution agreements with state treasury departments and administrators of unclaimed property under which the life insurers agreed to procedures for comparing their previously issued 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, in some cases at a negotiated rate, to the state if the beneficiary could not be found, and paying penalties to the state, if required. The amounts publicly reported to have been paid to beneficiaries and/or escheated to the states have been substantial.

State insurance regulators have initiated targeted multi-state examinations of life insurance companies with respect to the companies' claims paying practices and use of a Death Database to identify unreported deaths in their life insurance policies, annuity contracts and retained asset accounts, despite having 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. 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 systems and 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 substantial administrative and/or examination fees to the insurance regulators in connection with the settlement or consent agreements.

The Company and certain of its subsidiaries as well as certain other insurance companies from whom the Company has coinsured blocks of life insurance and annuity policies are subject to unclaimed property audits and/or targeted multi-state examinations by insurance regulators similar to those described above. It is possible that the audits, examinations and/or the enactment of state laws similar to the Unclaimed Benefits Act could result in additional payments to beneficiaries, additional escheatment of funds deemed abandoned under state laws, payment of administrative penalties and/or examination fees to state authorities, and changes to the Company's procedures for identifying unreported deaths and escheatment of abandoned property. It is possible any such additional payments and any costs related to changes in Company procedures could materially impact the Company's financial condition and/or results of operations. It is also possible that life insurers, including the Company, may be subject to claims, regulatory actions, law enforcement actions, and civil litigation arising from their prior business practices, unclaimed property practices or related audits and examinations. Any resulting liabilities, payments or costs, including initial and ongoing costs of changes to the Company's procedures or systems, could be significant and could have a material adverse effect on the Company's financial condition and/or results of operations.

During December 2012, the West Virginia Treasurer filed actions against the Company and its subsidiary West Coast Life Insurance Company in West Virginia state court (State of West Virginia ex rel. John D. Perdue v. Protective Life Insurance Company; State of West Virginia ex rel. John D. Perdue v. West Coast Life Insurance Company; Defendants' Motions to Dismiss granted on December 27, 2013; Notice of Appeal filed on January 27, 2014; dismissal reversed by the West Virginia Supreme Court of Appeals on June 16, 2015; Petition for Rehearing filed by Defendant insurance companies denied on September 21, 2015). The actions, which also name numerous other life insurance companies, allege that the companies violated the West Virginia Uniform Unclaimed Property Act, seek to compel compliance with the Act, and seek payment of unclaimed property, interest, and

104

penalties. While the legal theory or theories that may give rise to liability in the West Virginia Treasurer litigation are uncertain, it is possible that other jurisdictions may pursue similar actions. The Company does not currently believe that losses, if any, arising from the West Virginia Treasurer litigation will be material. The Company cannot, however, predict whether other jurisdictions will pursue similar actions or if they do, whether such actions will have a material impact on the Company's financial condition and/or results of operations.

New and amended regulations regarding the standard of care or standard of conduct applicable to investment professionals, insurance agencies, and financial institutions that recommend or sell annuities may have a material adverse impact on our ability to sell annuities and other products, to retain in-force business and on our financial condition or results of operations.

Sales of life insurance policies, contracts, and annuities offered by the Company are subject to regulations relating to sales practices adopted by a variety of federal and state regulatory authorities. Certain annuities and life insurance policies such as variable annuities and variable universal life insurance are regulated under the federal securities laws administered by the U.S. Securities and Exchange Commission (the “SEC”). On April 18, 2018, the SEC voted to propose rulemakings and interpretations relating to the standard of conduct applicable to broker-dealers, investment advisers, and their representatives when making certain recommendations to retail customers. Specifically, under the proposed regulations, a broker-dealer would be required to act in the best interest of a retail customer when recommending any securities transaction or investment strategy involving securities to a retail customer. The SEC also proposed an interpretation reaffirming and, in some cases, clarifying its views of the fiduciary duty that investment advisers owe to their clients. Another SEC proposal would require broker-dealers and investment advisers to provide each customer with a summary of the nature of the customer’s relationship with the investment professional, as well as a restriction on the use of the terms “adviser” and “advisor” by broker-dealers.

In addition, broker-dealers, insurance agencies and other financial institutions sell the Company’s annuities to employee benefit plans governed by provisions of the Employee Retirement Income Security Act (“ERISA”) and Individual Retirement Accounts (“IRAs”) that are governed by similar provisions under the Internal Revenue Code (the “Code”). Consequently, our activities and those of the firms that sell the Company’s products are subject to restrictions that require ERISA fiduciaries to perform their duties solely in the interests of ERISA plan participants and beneficiaries, and that prohibit ERISA fiduciaries from causing a covered plan or retirement account to engage in certain prohibited transactions absent an exemption. In general, the prohibited transaction provisions of ERISA and the Code restrict the receipt of compensation from third parties in connection with the provision of investment advice to ERISA plans and participants and IRAs.

In April of 2016, the U.S. Department of Labor (the “DOL”) issued new regulations expanding the definition of “investment advice fiduciary” under ERISA. These new regulations increased the number of circumstances in which the Company and broker-dealers, insurance agencies and other financial institutions that sell the Company’s products could be deemed a fiduciary when providing investment advice with respect to ERISA plans or IRAs. The DOL also issued amendments to long-standing exemptions from the provisions of ERISA and the Code that prohibit fiduciaries from engaging in certain types of transactions (“Prohibited Transaction Exemptions”) and adopted new Prohibited Transaction Exemptions.

Organizations that opposed the DOL’s fiduciary regulations have filed lawsuits aimed at overturning them. On March 15, 2018, the U.S. Court of Appeals for the Fifth Circuit issued a ruling vacating all aspects of the DOL’s fiduciary “rule,” including the changes to the definition of “investment advice fiduciary,” the creation of the Best Interest Contract Exemption, and the amendments to existing Prohibited Transaction Exemptions. This ruling is subject to challenge on appeal by the DOL or an intervening third party, however, and other courts considering the same or similar issues may reach a different legal conclusion.

In addition to the foregoing, the NAIC is considering revisions to the Suitability in Annuity Transactions Model Regulation which, if adopted by regulators, would impose a stricter standard of care upon insurers who sell annuities. Likewise, several states are considering legislation or regulatory measures that would implement new requirements and standards applicable to the sale of annuities and, in some cases, life insurance products. These standards vary widely in scope, applicability and timing of implementation. The adoption and enactment of these or any revised standards as law or regulation could have a material adverse effect upon the manner in which the Company's products are sold.

There remains significant uncertainty surrounding the final form that these regulations may take. Our current distributors may continue to move forward with their plans to limit the number of products they offer, including the types of products offered by the Company. The Company may find it necessary to change sales representative and/or broker compensation, to limit the assistance or advice it can provide to owners of the Company’s annuities, to replace or engage additional distributors, or otherwise change the manner in which it designs and supports sales of its annuities. In addition, the Company continues to incur expenses in connection with initial and ongoing compliance obligations with respect to such rules, and in the aggregate these expenses may be significant. Any of the foregoing regulatory, legislative or judicial measures or the reaction to such activity by consumers or other members of the insurance industry could have a material adverse impact on our ability to sell annuities and other products, to retain in-force business, and on our financial condition or results of operations.

The Company may be subject to regulation, investigations, enforcement actions, fines and penalties imposed by the SEC, FINRA and other federal and international regulators in connection with its business operations.

Certain life insurance policies, contracts, and annuities offered by the Company are subject to regulation under the federal securities laws administered by the SEC. The federal securities laws contain regulatory restrictions and criminal, administrative, and private remedial provisions. From time to time, the SEC and the Financial Industry Regulatory Authority (“FINRA”) examine or investigate the activities of broker-dealers and investment advisors, including the Company’s affiliated broker-dealers and investment advisers. These examinations or investigations often focus on the activities of the registered representatives and registered investment advisers doing business through such entities and the entities’ supervision of those persons. It is possible

105

that any examination or investigation could lead to enforcement action by the regulator and/or may result in payments of fines and penalties, payments to customers, or both, as well as changes in systems or procedures of such entities, any of which could have a material adverse effect on the Company’s financial condition or results of operations.

The Company may also be subject to regulation by governments of the countries in which it currently does, or may in the future, do, business, as well as regulation by the U.S. Government with respect to its operations in foreign countries, such as the Foreign Corrupt Practices Act. Penalties for violating the various laws governing the Company’s business in other countries may include restrictions upon business operations, fines and imprisonment, both within the U.S. and abroad. U.S. enforcement of anti-corruption laws continues to increase in magnitude, and penalties may be substantial.

The Company is subject to conditions and requirements set forth in the Telephone Consumer Protection Act (“TCPA”), which places restrictions on the use of automated telephone and facsimile machines. Class action lawsuits alleging violations of the act have been filed against a number of companies, including life insurance carriers. These class action lawsuits contain allegations that defendant carriers were vicariously liable for the alleged wrongful conduct of agents who violated the TCPA. Some of the class actions have resulted in substantial settlements against other insurers. Any such actions against the Company could result in a material adverse effect upon our financial condition or results of operations.

Other types of regulation that could affect the Company and its subsidiaries include, but are not limited to, insurance company investment laws and regulations, state statutory accounting and reserving practices, antitrust laws, minimum solvency requirements, enterprise risk requirements, state securities laws, federal privacy laws, cybersecurity regulation, technology and data regulations, insurable interest laws, federal anti-money laundering and anti-terrorism laws, employment and immigration laws (including laws in Alabama where over half of the Company’s employees are located), and because the Company owns and operates real property, state, federal, and local environmental laws. Under some circumstances, severe penalties may be imposed for breach of these laws.

The Company cannot predict what form any future changes to laws and/or regulations affecting participants in the financial services sector and/or insurance industry, including the Company and its competitors or those entities with which it does business, may take, or what effect, if any, such changes may have.

The Company's ability to enter into certain transactions is influenced by how such a transaction might affect Dai-ichi Life's taxation in Japan.

Changes to tax law, such as the effect of the Tax Reform Act enacted on December 22, 2017, or interpretations of existing tax law could adversely affect the Company and its ability to compete with non-insurance products or reduce the demand for certain insurance products.

In general, existing law exempts policyholders from current taxation on the increase in value of most insurance and annuity products during these products’ accumulation phase. This favorable tax treatment provides some of the Company’s products with a competitive advantage over products offered by non-insurance companies. To the extent that the law is revised to either reduce the tax-deferred status of life insurance and annuity products, or to establish the tax-deferred status of competing products, then all life insurance companies, including the Company and its subsidiaries, would be adversely affected with respect to their ability to sell their products. Furthermore, such changes would generally cause increased surrenders of existing life insurance and annuity products. For example, a change in law that further restricts the deductibility of interest expense when a business owns a life insurance product would result in increased surrenders of these products.

The Company is subject to corporate income, excise, franchise, and premium taxes. Federal tax law provides certain benefits to the Company, such as the deferral of current taxation on derivatives' and securities' economic income and the current deduction for future policy benefits and claims. The Tax Cuts and Jobs Act (the "Tax Reform Act"), which was enacted in December 2017, will require the Company to report higher amounts of taxable income both now and in the future. However, the legislation also significantly reduced the corporate income tax rate. Overall, the Company expects to pay less income tax in the future.

The Company's mid-2005 transition from relying on reinsurance for newly-written traditional life products to reinsuring some of these products' reserves into its captive insurance companies resulted in a net reduction in its current taxes, offset by an increase in its deferred taxes. The resulting benefit of reduced current taxes is attributed to the applicable life products and is an important component of the profitability of these products. The Tax Reform Act, with its overall lower tax rate, has decreased the economic tax benefit associated with these products. Ultimately, the profitability and competitive position of these products is dependent on the Company’s ability to continue deducting its provision for future policy benefits and claims and the Company's ability to generate taxable income.

CONSOLIDATED EARNINGS RATIOS

The following table sets forth, for the years and periods ended, Protective Life Insurance Company’s (the “Company”) ratios of:

· Consolidated earnings to fixed charges.

· Consolidated earnings to fixed charges before interest credited on investment products.

	Successor Company					Predecessor Company
	For The Three Months Ended		For The Year Ended		February 1, 2015	January 1, 2015
	March 31,		December 31,		to	to	For The Year Ended
	2018	2017	2017	2016	December 31, 2015	January 31, 2015	December 31, 2014
Ratio of Consolidated Earnings to Fixed Charges(1)	1.1	1.4	1.5	1.6	1.3	2.5	1.8
Ratio of Consolidated Earnings to Fixed Charges Before Interest Credited on Investment Products(2)	1.5	2.9	3.6	4.0	3.3	13.9	7.0

(1)The Company calculates the ratio of “Consolidated Earnings to Fixed Charges” by dividing the sum of income from continuing operations before income tax (BT), interest expense (which includes an estimate of the interest component of operating lease expense) (I) and interest credited on investment products (IP) by the sum of interest expense (I) and interest credited on investment products (IP). The formula for this ratio is: (BT+I+IP)(I+IP). The Company continues to sell investment products that credit interest to the contract holder. Investment products include products such as guaranteed investment contracts, annuities, and variable universal life interest credited insurance policies. The inclusion of interest credited on investment products results in a negative impact on the ratio of earnings to fixed charges because the effect of increases in interest credited to contract holders more than offsets the effect of the increase in earnings.

(2)The Company calculates the ratio of “Consolidated Earnings to Fixed Charges Before Interest Credited on Investment Products” by dividing the sum of income from continuing operations before income tax (BT) and interest expense (I) by interest expense (I). The formula for this calculation, therefore, would be: (BT+I)/I.

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. 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 months ended March 31, 2018, are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2018. 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, 2017.

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.

During the first quarter of 2018, the Company recorded an adjustment related to prior periods to correct an error pertaining to certain reinsurance allowances. The adjustment resulted in a $6.2 million increase to other liabilities, a corresponding increase in other operating expenses, and a $4.9 million decrease to net income for the three months ended March 31, 2018. The Company concluded that the adjustment was not quantitatively or qualitatively material to previously reported annual or interim periods. As a result, this adjustment was recorded by the Company within the presented interim consolidated condensed financial statements for the three months ended March 31, 2018.

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, 2017. There were no significant changes to the Company's accounting policies during the three months ended March 31, 2018 other than those discussed below.

Property and Casualty Insurance Products

Property and casualty insurance products include service contract business, surety bonds, and guaranteed asset protection ("GAP"). Premiums and fees associated with service contracts and GAP products are recognized based on expected claim patterns. For all other products, premiums are generally recognized over the terms of the contract on a pro-rata basis. Commissions and fee income associated with other products are recognized as earned when the related services are provided to the customer. Unearned premium reserves are maintained for the portion of the premiums that is related to the unexpired period of the policy. Benefit reserves are recorded when insured events occur. Benefit reserves include case basis reserves for known but unpaid claims as of the balance sheet date as well as incurred but not reported ("IBNR") reserves for claims where the insured event has occurred but has not been reported to the Company as of the balance sheet date. The case basis reserves and IBNR are calculated based on historical experience and on assumptions relating to claim severity and frequency, the level of used vehicle prices, and other factors. These assumptions are modified as necessary to reflect anticipated trends.

Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers. In consideration of the amendments in this Update, the Company revised its recognition pattern for administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. The Company will recognize these fees on a claims occurrence basis in future periods. To reflect this change in accounting principle, the Company recorded a cumulative effect adjustment as of January 1, 2018 that resulted in a decrease in retained earnings of $88.6 million. The pre-tax impact to each affected line item on the Company’s financial statements is reflected in the table below:

Accounting Pronouncements Recently 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 adopted this Update using the modified retrospective approach via a cumulative effect adjustment to retained earnings as of January 1, 2018. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, impacted certain revenues associated with the Company's Asset Protection products. The lines of business to which the revised guidance applies are not material to the Company’s financial statements. In consideration of the amendments in this Update, the Company revised its recognition pattern for administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. The Company will recognize these fees on a claims occurrence basis in future periods. To reflect this change in accounting principle, the Company recorded a cumulative effect adjustment as of January 1, 2018 that resulted in a decrease in retained earnings of $88.6 million. See above for additional discussion.

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 were applied on a modified retrospective basis. The Company recorded a cumulative-effect adjustment at the date of adoption, January 1, 2018, transferring unrealized gains and losses on available-for-sale equity securities to retained earnings from accumulated other comprehensive income. The impact of this adjustment, net of income tax, resulted in a $10.6 million increase to retained earnings and a corresponding decrease to accumulated other comprehensive income, resulting in no net impact to consolidated shareowner's equity. The Company has updated its disclosures in Note 4, Investment Operations and Note 5, Fair Value of Financial Instruments in accordance with the ASU.

ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include:Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2017 using the retrospective method. There was no financial impact.

ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. There was no impact to the Company on adoption.

ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the Update provide a specific test by which an entity may determine whether an acquisition involves a set of assets or a business. The amendments in the Update are to be applied prospectively for periods beginning after December 15, 2017. The Company has reviewed the revised requirements, and does not anticipate that the changes will impact its policies or recent conclusions related to its acquisition activities.

ASU No. 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this update require entities to disaggregate the current-service-cost component from other components of net benefit cost and present it with other current compensation costs in the income statement. The other components of net benefit cost must be presented outside of income from operations if that subtotal is presented. In addition, the Update requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. As provided for in the ASU, the Company expects to apply the provisions of the statement retrospectively for components of net periodic pension costs and prospectively for capitalization of the service costs component of net periodic costs and net periodic postretirement benefits. The Update did not impact the Company’s financial position, results of operations, or current disclosures.

Accounting Pronouncements Not Yet Adopted

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. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine the financial and operational impact of implementing the Update, as well as to determine whether early adoption of the revised guidance is practicable.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update are designed to permit hedge accounting to be applied to a broader range of hedging strategies as well as to more closely align hedge accounting and risk management objectives. Specific provisions include requiring changes in the fair value of a hedging instrument be recorded in the same income statement line as the hedged item when it affects earnings. In addition, after a hedge has initially qualified as an effective hedge the Update permits the use of a qualitative hedge effectiveness test in subsequent periods. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact this standard will have on its operations and financial results.

MONY CLOSED BLOCK OF BUSINESS

3 Months Ended

Mar. 31, 2018

Closed Block Disclosure [Abstract]

MONY CLOSED BLOCK OF BUSINESS

MONY CLOSED BLOCK OF BUSINESS

In 1998, MONY Life Insurance Company (“MONY”) converted from a mutual insurance company to a stock corporation (“demutualization”). In connection with its demutualization, an accounting mechanism known as a closed block (the “Closed Block”) was established for certain individuals’ participating policies in force as of the date of demutualization. Assets, liabilities, and earnings of the Closed Block are specifically identified to support its participating policyholders. The Company acquired the Closed Block in conjunction with the acquisition of MONY in 2013.

Assets allocated to the Closed Block inure solely to the benefit of each Closed Block’s policyholders and will not revert to the benefit of MONY or the Company. No reallocation, transfer, borrowing or lending of assets can be made between the Closed Block and other portions of MONY’s general account, any of MONY’s separate accounts or any affiliate of MONY without the approval of the Superintendent of The New York State Department of Financial Services (the “Superintendent”). Closed Block assets and liabilities are carried on the same basis as similar assets and liabilities held in the general account.

The excess of Closed Block liabilities over Closed Block assets (adjusted to exclude the impact of related amounts in AOCI) at the acquisition date of October 1, 2013, represented the estimated maximum future post-tax earnings from the Closed Block that would be recognized in income from continuing operations over the period the policies and contracts in the Closed Block remain in force. In connection with the acquisition of MONY, the Company developed an actuarial calculation of the expected timing of MONY’s Closed Block’s earnings as of October 1, 2013. Pursuant to the acquisition of the Company by Dai-ichi Life, this actuarial calculation of the expected timing of MONY's Closed Block earnings was recalculated and reset as February 1, 2015, along with the establishment of a policyholder dividend obligation as of such date.

If the actual cumulative earnings from the Closed Block are greater than the expected cumulative earnings, only the expected earnings will be recognized in the Company’s net income. Actual cumulative earnings in excess of expected cumulative earnings at any point in time are recorded as a policyholder dividend obligation because they will ultimately be paid to Closed Block policyholders as an additional policyholder dividend unless offset by future performance that is less favorable than originally expected. If a policyholder dividend obligation has been previously established and the actual Closed Block earnings in a subsequent period are less than the expected earnings for that period, the policyholder dividend obligation would be reduced (but not below zero). If, over the period the policies and contracts in the Closed Block remain in force, the actual cumulative earnings of the Closed Block are less than the expected cumulative earnings, only actual earnings would be recognized in income from continuing operations. If the Closed Block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from assets outside the Closed Block.

Many expenses related to Closed Block operations, including amortization of VOBA, are charged to operations outside of the Closed Block; accordingly, net revenues of the Closed Block do not represent the actual profitability of the Closed Block operations. Operating costs and expenses outside of the Closed Block are, therefore, disproportionate to the business outside of the Closed Block.

Summarized financial information for the Closed Block as of March 31, 2018 and December 31, 2017 is as follows:

RMBS and CMBS had gross unrealized losses greater than twelve months of $18.0 million and $33.6 million, respectively, as of March 31, 2018. 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 $7.9 million as of March 31, 2018. This category predominately includes student loan backed auction rate securities whose underlying collateral is at least 97% guaranteed by the Federal Family Education Loan Program (“FFELP”). At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary.

The U.S. government-related securities and the other government-related securities had gross unrealized losses greater than twelve months of $46.9 million and $7.4 million as of March 31, 2018, respectively. 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 $62.7 million as of March 31, 2018. These declines were related to changes in interest rates.

The corporate securities category had gross unrealized losses greater than twelve months of $849.8 million as of March 31, 2018. 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 March 31, 2018, the Company had a total of 2,428 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, 2017:

As ofMarch 31, 2018, the Company had securities in its available-for-sale portfolio which were rated below investment grade of $1.8 billion and had an amortized cost of $1.8 billion. In addition, included in the Company’s trading portfolio, the Company held $217.2 million of securities which were rated below investment grade. Approximately $306.5 million of the available-for-sale and trading securities that were below investment grade were not publicly traded.

During the three months ended March 31, 2018 and 2017, the Company recorded no other-than-temporary impairments on held-to-maturity securities.

The Company’s held-to-maturity securities had$30.3 million of gross unrecognized holding gains and $56.0 million of gross unrecognized holding losses by maturity as of March 31, 2018. The Company does not consider these unrecognized holding losses to be other-than-temporary based on certain positive factors associated with the securities which include credit ratings of the guarantor, financial health of the issuer and guarantor, continued access of the issuer to capital markets and other pertinent information. 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 $76.6 million of gross unrecognized holding gains and $19.2 million of gross unrecognized holding losses by maturity as of December 31, 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.

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 March 31, 2018 and December 31, 2017, 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 March 31, 2018, no payments have been made or required related to this guarantee.

FAIR VALUE OF FINANCIAL INSTRUMENTS

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 March 31, 2018:

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 approximately92.4%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 three months ended March 31, 2018.

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 mainlyconsists of residential mortgage-backed securities, commercial mortgage-backed securities, and other asset-backed securities (collectively referred to as asset-backed securities or “ABS”). As ofMarch 31, 2018, the Company held$5.4 billionof 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 ofMarch 31, 2018, the Company held $538.7 million of Level 3 ABS, which included $503.8 million of other asset-backed securities classified as available-for-sale and $34.9 million of other asset-backed securities classified as trading. These securities are predominantly ARS whose underlying collateral is at least97%guaranteed by the FFELP. 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 March 31, 2018, the Company classified approximately $32.1 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 March 31, 2018, the Company classified approximately $631.7 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 March 31, 2018, the Company held approximately $65.5 million of equity securities classified as Level 2 and Level 3. Of this total, $65.5 million represents Federal Home Loan Bank (“FHLB”) stock. The Company believes that the cost of the FHLB stock approximates fair value.

Other Long-Term Investments and Other Liabilities

Other long-term investments and other liabilities consist entirely of free-standing and embedded derivative financial instruments. Refer to Note 6,Derivative Financial Instrumentsfor 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 ofMarch 31, 2018,82.6% of derivatives based upon notional values were priced using exchange prices or independent broker quotations. The remaining derivatives were priced by pricing valuation models, which utilize observable market data inputs to the extent they are available. Inputs used to value derivatives include, but are not limited to, interest swap rates, credit spreads, interest rate and equity market volatility indices, equity index levels, and treasury rates. The Company performs monthly analysis on derivative valuations that includes both quantitative and qualitative analyses.

Derivative instruments classified as Level 1 generally include futures and options, which are traded on active exchange markets.

Derivative instruments classified as Level 2 primarily include swaps, options, and swaptions, which are traded over-the-counter. Level 2 also includes certain centrally cleared derivatives. These derivative valuations are determined using independent broker quotations, which are corroborated with observable market inputs.

Derivative instruments classified as Level 3 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 guaranteed living withdrawal benefits ("GLWB") embedded derivative is derived through the income method of valuation using a valuation model that projects future cash flows using multiple risk neutral stochastic equity scenarios and policyholder behavior assumptions. The risk neutral scenarios are generated using the current swap curve and projected equity volatilities and correlations. The projected equity volatilities are based on a blend of historical volatility and near- term equity market implied volatilities. The equity correlations are based on historical price observations. For policyholder behavior assumptions, expected lapse and utilization assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from theRuark 2015 ALB table with attained age factors varying from 91.1% - 106.6%. The present value of the cash flows is determined using the discount rate curve, which is based uponLIBORplus 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 method of valuation using a valuation model that projects future cash flows using current index values and volatility, the hedge budget used to price the product, and policyholder assumptions (both elective and non-elective). For policyholder behavior assumptions, expected lapse and withdrawal assumptions are used and updated for actual experience, as necessary. The Company assumes age-based mortality from the 1994 Variable Annuity MGDB mortality table modified with company experience, with attained age factors varying from 46% - 113%. The present value of the cash flows is determined using the discount rate curve, which is based upon LIBOR up to one year and constant maturity treasury rates plus a credit spread (to represent the Company’s non-performance risk) thereafter. Policyholder 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 34% - 152%. The present value of the cash flows is determined using the discount rate curve, which is baseduponLIBORup 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 also reported in earnings. As of March 31, 2018, 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 $134.1 million. As a result, changes in the fair value of the embedded derivatives are largely offset by the changes in fair value of the related investments and each are reported in earnings. The fair value of the embedded derivative is considered a Level 3 valuation due to the unobservable nature of the policy liabilities.

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 March 31, 2018 was $103.1 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 $48.8 million as of March 31, 2018. As of March 31, 2018, no payments have been made under this agreement, however, certain interest support agreement obligations to Golden Gate II of approximately $4.8 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.

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 March 31, 2018 was $49.4 million. As of March 31, 2018, 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 March 31, 2018, was $4.8 million. As of March 31, 2018, 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 March 31, 2018, was a liability of $101.8 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 March 31, 2018 is $81.4 million.

Separate Accounts

Separate account assets are invested in open-ended mutual funds and are included in Level 1.

The Company has considered all reasonably available quantitative inputs as of March 31, 2018, but the valuation techniques and inputs used by somebrokers in pricing certain financial instruments are not shared with the Company. This resulted in $49.1 million of financial instruments being classified as Level 3 as of March 31, 2018. Of the $49.1 million, $35.1 million are other asset-backed securities, and $14.0 million are corporate securities.

In certain cases the Company has determined that book value materially approximates fair value. As of March 31, 2018, the Company held $65.5 million of financial instruments where book value approximates fair value which were predominantly FHLB stock.

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 December 31, 2017, but the valuation techniques and inputs used by some brokers in pricing certain financial instruments are not shared with the Company. This resulted in $50.0 million of financial instruments being classified as Level 3 as of December 31, 2017. Of the $50.0 million, $35.4 million are other asset backed securities and $14.6 million are corporate securities.

In certain cases the Company has determined that book value materially approximates fair value. As of December 31, 2017, the Company held $65.5 million of financial instruments where book value approximates fair value which are predominantly FHLB stock.

The asset-backed securities classified as Level 3 are predominantly ARS. A change in the paydown rate (the projected annual rate of principal reduction) of the ARS can significantly impact the fair value of these securities. A decrease in the paydown rate would increase the projected weighted average life of the ARS and increase the sensitivity of the ARS’ fair value to changes in interest rates. An increase in the liquidity premium would result in a decrease in the fair value of the securities, while a decrease in the liquidity premium would increase the fair value of these securities. The liquidation value for these securities are sensitive to the issuer's available cash flows and ability to redeem the securities, as well as the current holders' willingness to liquidate at the specified prices.

The fair value of corporate bonds classified as Level 3 is sensitive to changes in the interest rate spread over the corresponding U.S. Treasury rate. This spread represents a risk premium that is impacted by company specific and market factors. An increase in the spread can be caused by a perceived increase in credit risk of a specific issuer and/or an increase in the overall market risk premium associated with similar securities. The fair values of corporate bonds are sensitive to changes in spread. When holding the treasury rate constant, the fair value of corporate bonds increases when spreads decrease and decreases when spreads increase.

The fair value of the GLWB embedded derivative is sensitive to changes in the discount rate which includes the Company’s nonperformance risk, volatility, lapse, and mortality assumptions. The volatility assumption is an observable input as it is based on market inputs. The Company’s nonperformance risk, lapse, and mortality are unobservable. An increase in the three unobservable assumptions would result in a decrease in the fair value of the liability and conversely, if there is a decrease in the assumptions the fair value would increase. The fair value is also dependent on the assumed policyholder utilization of the GLWB where an increase in assumed utilization would result in an increase in the fair value of the liability and conversely, if there is a decrease in the assumption, the fair value would decrease.

The fair value of the FIA embedded derivative is predominantly impacted by observable inputs such as discount rates and equity returns. However, the fair value of the FIA embedded derivative is sensitive to non-performance risk, which is unobservable. The value of the liability increases with decreases in the discount rate and non-performance risk and decreases with increases in the discount rate and nonperformance risk. The value of the liability increases with increases in equity returns and the liability decreases with a decrease in equity returns.

The fair value of the IUL embedded derivative is predominantly impacted by observable inputs such as discount rates and equity returns. However, the fair value of the IUL embedded derivative is sensitive to non-performance risk, which is unobservable. The value of the liability increases with decreases in the discount rate and non-performance risk and decreases with increases in the discount rate and non-performance risk. The value of the liability increases with increases in equity returns and the liability decreases with a decrease in equity returns.

For the three months ended March 31, 2017, there were an immaterial amount of securities transferred into Level 3.

For the three months ended March 31, 2017, $9.3 million of securities transferred into Level 2. This amount was transferred from Level 3. These transfers resulted from securities that were priced internally using significant unobservable inputs where market observable inputs were not available in previous periods but were priced by independent pricing services or brokers as of March 31, 2017.

For the three months ended March 31, 2017, there were no securities transferred from Level 2 to Level 1.

For the three months ended March 31, 2017, there were no securities transferred from Level 1.

     Total realized and unrealized gains (losses) on Level 3 assets and liabilities are primarily reported in either realized investment gains (losses) within the consolidated condensed statements of income (loss) or other comprehensive income (loss) within shareowner’s equity based on the appropriate accounting treatment for the item.

Purchases, sales, issuances, and settlements, net, represent the activity that occurred during the period that results in a change of the asset or liability but does not represent changes in fair value for the instruments held at the beginning of the period. Such activity primarily relates to purchases and sales of fixed maturity securities and issuances and settlements of fixed indexed annuities.

The Company reviews the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. The asset transfers in the table(s) above primarily related to positions moved from Level 3 to Level 2 as the Company determined that certain inputs were observable.

The amount of total gains (losses) for assets and liabilities still held as of the reporting date primarily represents changes in fair value of trading securities and certain derivatives that exist as of the reporting date and the change in fair value of fixed indexed annuities.

Fair Value Measurements

Mortgage loans on real estate

The Company estimates the fair value of mortgage loans using an internally developed model. This model includes inputs derived by the Company based on assumed discount rates relative to the Company’s current mortgage loan lending rate and an expected cash flow analysis based on a review of the mortgage loan terms. The model also contains the Company’s determined representative risk adjustment assumptions related to credit and liquidity risks.

Policy loans

The Company believes the fair value of policy loans approximates book value. Policy loans are funds provided to policy holders in return for a claim on the policy. The funds provided are limited to the cash surrender value of the underlying policy. The nature of policy loans is to have a negligible default risk as the loans are fully collateralized by the value of the policy. Policy loans do not have a stated maturity and the balances and accrued interest are repaid either by the policyholder or with proceeds from the policy. Due to the collateralized nature of policy loans and unpredictable timing of repayments, the Company believes the fair value of policy loans approximates carrying value.

Fixed maturities, held-to-maturity

The Company estimates the fair value of its fixed maturity, held-to-maturity securities using internal discounted cash flow models. The discount rates used in the model are based on a current market yield for similar financial instruments.

Stable value product and other investment contract balances

The Company estimates the fair value of stable value product account balances and other investment contract balances (included in Future policy benefits and claims as well as Other policyholder funds line items on our balance sheet) using models based on discounted expected cash flows. The discount rates used in the models are based on a current market rate for similar financial instruments.

Non-recourse funding obligations

The Company estimates the fair value of its non-recourse funding obligations using internal discounted cash flow models. The discount rates used in the model are based on a current market yield for similar financial instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

Types of Derivative Instruments and Derivative Strategies

The Company utilizes a risk management strategy that incorporates the use of derivative financial instruments to reduce exposure to certain risks, including but not limited to, interest rate risk, currency exchange risk, volatility risk, and equity market risk. These strategies are developed through the Company’s analysis of data from financial simulation models and other internal and industry sources and are then incorporated into the Company’s risk management program.

Derivative instruments expose the Company to credit and market risk and could result in material changes from period to period. The Company attempts to minimize its credit risk by entering into transactions with highly rated counterparties. The Company manages the market risk by establishing and monitoring limits as to the types and degrees of risk that may be undertaken. The Company monitors its use of derivatives in connection with its overall asset/liability management programs and risk management strategies. In addition, all derivative programs are monitored by our risk management department.

Derivatives Related to Interest Rate Risk Management

Derivative instruments that are used as part of the Company’s interest rate risk management strategy include interest rate swaps, interest rate futures, interest rate caps, and interest rate swaptions.

Derivatives Related to Foreign Currency Exchange Risk Management

Derivative instruments that are used as part of the Company's foreign currency exchange risk management strategy include foreign currency swaps, foreign currency futures, foreign equity futures, and foreign equity options.

Derivatives Related to Risk Mitigation of Certain Annuity Contracts

The Company may use the following types of derivative contracts to mitigate its exposure to certain guaranteed benefits related to VA contracts and fixed indexed annuities:

•Foreign Currency Futures

•Variance Swaps

•Interest Rate Futures

•Equity Options

•Equity Futures

•Credit Derivatives

•Interest Rate Swaps

•Interest Rate Swaptions

•Volatility Futures

•Volatility Options

•Funds Withheld Agreement

•Total Return Swaps

Other Derivatives

The Company and certain of its subsidiaries have derivatives with PLC. These derivatives consist of an interest support agreement, YRT premium support agreements, and portfolio maintenance agreements with PLC.

The Company has a funds withheld account that consists of various derivative instruments held by us that is used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument.

Accounting for Derivative Instruments

The Company records its derivative financial instruments in the consolidated balance sheet in “other long-term investments” and “other liabilities” in accordance with GAAP, which requires that all derivative instruments be recognized in the balance sheet at fair value. The change in the fair value of derivative financial instruments is reported either in the statement of income or in other comprehensive income (loss), depending upon whether it qualified for and also has been properly identified as being part of a hedging relationship, and also on the type of hedging relationship that exists.

For a derivative financial instrument to be accounted for as an accounting hedge, it must be identified and documented as such on the date of designation. For cash flow hedges, the effective portion of their realized gain or loss is reported as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged item impacts earnings. Any remaining gain or loss, the ineffective portion, is recognized in current earnings. For fair value hedge derivatives, their gain or loss as well as the offsetting loss or gain attributable to the hedged risk of the hedged item is recognized in current earnings. Effectiveness of the Company’s hedge relationships is assessed on a quarterly basis.

The Company reports changes in fair values of derivatives that are not part of a qualifying hedge relationship through earnings in the period of change. Changes in the fair value of derivatives that are recognized in current earnings are reported in “Realized investment gains (losses)-Derivative financial instruments.”

Derivative Instruments Designated and Qualifying as Hedging Instruments

Cash-Flow Hedges

• To hedge a fixed rate note denominated in a foreign currency, the Company entered into a fixed-to-fixed foreign currency swap in order to hedge the foreign currency exchange risk associated with the note. The cash flows received on the swap are identical to the cash flow paid on the note.

Derivative Instruments Not Designated and Not Qualifying as Hedging Instruments

The Company uses various other derivative instruments for risk management purposes that do not qualify for hedge accounting treatment. Changes in the fair value of these derivatives are recognized in earnings during the period of change.

Derivatives Related to Variable Annuity Contracts

• The Company uses equity futures, equity options, total return swaps, interest rate futures, interest rate swaps, interest rate swaptions, currency futures, volatility futures, volatility options, and variance swaps to mitigate the risk related to certain guaranteed minimum benefits, including GLWB, within its VA products. In general, the cost of such benefits varies with the level of equity and interest rate markets, foreign currency levels, and overall volatility.

• The Company markets certain VA products with a GLWB rider. The GLWB component is considered an embedded derivative, not considered to be clearly and closely related to the host contract.

• The Company has a funds withheld account that consists of various derivative instruments held by the Company that are used to hedge the GLWB and GMDB riders. The economic performance of derivatives in the funds withheld account is ceded to Shades Creek. The funds withheld account is accounted for as a derivative financial instrument.

Derivatives Related to Fixed Annuity Contracts

• The Company uses equity futures and options to mitigate the risk within its fixed indexed annuity products. In general, the cost of such benefits varies with the level of equity 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.

The following table sets forth realized investments gains and losses for the periods shown:

MORTGAGE LOANS

Mortgage Loans

The Company invests a portion of its investment portfolio in commercial mortgage loans. As of March 31, 2018, the Company’s mortgage loan holdings were approximately$6.8 billion. The Company has specialized in making loans on credit-oriented commercial properties, credit-anchored strip shopping centers, senior living facilities, and apartments. The Company’s underwriting procedures relative to its commercial loan portfolio are based, in the Company’s view, on a conservative and disciplined approach. The Company concentrates on a small number of commercial real estate asset types associated with the necessities of life (retail, multi-family, senior living, professional office buildings, and warehouses). The Company believes that these asset types tend to weather economic downturns better than other commercial asset classes in which it has chosen not to participate. The Company believes this disciplined approach has helped to maintain a relatively low delinquency and foreclosure rate throughout its history. The majority of the Company's mortgage loans portfolio was underwritten by the Company. From time to time, the Company may acquire loans in conjunction with an acquisition.

The Company's commercial mortgage loans are stated at unpaid principal balance, adjusted for any unamortized premium or discount, and net of valuation allowances. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Amortization of premiums and discounts is recorded using the effective yield method. Interest income, amortization of premiums and discounts and prepayment fees are reported in net investment income.

Certain of the mortgage loans have call options that occur within the next 12years. 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 March 31, 2018, assuming the loans are called at their next call dates, approximately $143.6 million of principal would become due for the remainder of 2018, $873.1 million in 2019 through 2023, $105.0 million in 2024 through 2028, and $2.0 million thereafter.

The Company offers a type of commercial mortgage loan under which the Company will permit a loan-to-value ratio of up to85%in exchange for a participating interest in the cash flows from the underlying real estate. As ofMarch 31, 2018, andDecember 31, 2017, approximately $672.1 million and $669.3 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 thethreemonths endedMarch 31, 2018and2017, the Company recognized$7.3 million and $6.8 million, respectively, of participating mortgage loan income.

As ofMarch 31, 2018,noneof the Company's invested assets consisted of nonperforming mortgage loans, restructured mortgage loans, or mortgage loans that were foreclosed and were converted to real estate properties. For all mortgage loans, the impact of troubled debt restructurings is generally reflected in our investment balance and in the allowance for mortgage loan credit losses. During the three months ended March 31, 2018, the Company recognized no troubled debt restructurings and the Company did not identify any loans whose principal was permanently impaired.

TheCompany’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 March 31, 2018, the Company did not have mortgage loans not subject to a pooling and servicing agreement that were nonperforming mortgage loans, restructured, or mortgage loans that were foreclosed and were converted to real estate properties. The Company did not foreclose on any nonperforming loans not subject to a pooling and servicing agreement during the three months ended March 31, 2018.

As of March 31, 2018,noneof the loans subject to a pooling and servicing agreement were nonperforming or restructured. The Company did not foreclose on any nonperforming loans subject to a pooling and servicing agreement during the three months ended March 31, 2018.

As of March 31, 2018 and December 31, 2017, there were no allowances for mortgage loan credit losses. Due to the Company’s loss experience and nature of the loan portfolio, the Company believes that a collectively evaluated allowance would be inappropriate. The Company believes an allowance calculated through an analysis of specific loans that are believed to have a higher risk of credit impairment provides a more accurate presentation of expected losses in the portfolio and is consistent with the applicable guidance for loan impairments in ASC Subtopic 310. Since the Company uses the specific identification method for calculating the allowance, it is necessary to review the economic situation of each borrower to determine those that have higher risk of credit impairment. The Company has a team of professionals that monitors borrower conditions such as payment practices, borrower credit, operating performance, and property conditions, as well as ensuring the timely payment of property taxes and insurance. Through this monitoring process, the Company assesses the risk of each loan. When issues are identified, the severity of the issues are assessed and reviewed for possible credit impairment. If a loss is probable, an expected loss calculation is performed and an allowance is established for that loan based on the expected loss. The expected loss is calculated as the excess carrying value of a loan over either the present value of expected future cash flows discounted at the loan’s original effective interest rate, or the current estimated fair value of the loan’s underlying collateral. A loan may be subsequently charged off at such point that the Company no longer expects to receive cash payments, the present value of future expected payments of the renegotiated loan is less than the current principal balance, or at such time that the Company is party to foreclosure or bankruptcy proceedings associated with the borrower and does not expect to recover the principal balance of the loan.

A charge off is recorded by eliminating the allowance against the mortgage loan and recording the renegotiated loan or the collateral property related to the loan as investment real estate on the balance sheet, which is carried at the lower of the appraised fair value of the property or the unpaid principal balance of the loan, less estimated selling costs associated with the property. The Company did not have any charge offs or recovery for the three months ended March 31, 2018. 

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.

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

Mortgage loans that were modified in a troubled debt restructuring as of March 31, 2018 and December 31, 2017 were as follows:

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL

GOODWILL

The balance of goodwill for the Company as of March 31, 2018 was $793.5 million. There has been no change to goodwill during the three months ended March 31, 2018.

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 2017, the Company performed its annual evaluation of goodwill based on information as of October 1, 2017, and determined that no adjustment to impair goodwill was necessary. During the three months ended March 31, 2018, 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.

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 than90 days. The market value of securities to be repurchased is monitored and collateral levels are adjusted where appropriate to protect the counterparty against credit exposure. Cash received is invested in fixed maturity securities, and the agreements provided for net settlement in the event of default or on termination of the agreements. As of March 31, 2018, the fair value of securities pledged under the repurchase program was $753.6 million, and the repurchase obligation of $665.0 million was included in the Company’s consolidated condensed balance sheets (at an average borrowing rate of 173 basis points). During the three months ended March 31, 2018, the maximum balance outstanding at any one point in time related to these programs was $885.0 million. The average daily balance was $808.0 million (at an average borrowing rate of149basis points) during thethreemonths endedMarch 31, 2018. As ofDecember 31, 2017, the fair value of securities pledged under the repurchase program was $1,006.6 million, and the repurchase obligation of $885.0 million was included in the Company's consolidated condensed balance sheets (at an average borrowing rate of142basis points). During2017, the maximum balance outstanding at any one point in time related to these programs was $988.5 million. The average daily balance was$624.7 million(at an average borrowing rate of101basis points) during the year endedDecember 31, 2017.

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 March 31, 2018, securities with a market value of $107.0 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 March 31, 2018, the fair value of the collateral related to this program was $113.9 million and the Company has an obligation to return $113.9 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 March 31, 2018 and December 31, 2017:

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 increases the cost of future assessments or alters future premium tax offsets received in connection with guaranty fund assessments. The Company cannot predict the amount, nature or timing of any future assessments or legislation, any of which could have a material and adverse impact on the Company's financial condition or results of operations.

A number of civil jury verdicts have been returned against insurers, broker-dealers, and other providers of financial services involving sales, refund or claims practices, alleged agent misconduct, failure to properly supervise representatives, relationships with agents or persons with whom the insurer does business, and other matters. Often these lawsuits have resulted in the award of substantial judgments that are disproportionate to the actual damages, including material amounts of punitive and non-economic compensatory damages. In some states, juries, judges, and arbitrators have substantial discretion in awarding punitive and non-economic compensatory damages which creates the potential for unpredictable material adverse judgments or awards in any given lawsuit or arbitration. Arbitration awards are subject to very limited appellate review. In addition, in some class action and other lawsuits, companies have made material settlement payments. The financial services and insurance industries in particular are also sometimes the target of law enforcement and regulatory investigations relating to the numerous laws and regulations that govern such companies. Some companies have been the subject of law enforcement or regulatory actions or other actions resulting from such investigations. The Company, in the ordinary course of business, is involved in such matters.

The Company establishes liabilities for litigation and regulatory actions when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. For matters where a loss is believed to be reasonably possible, but not probable, no liability is established. For such matters, the Company may provide an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made. The Company reviews relevant information with respect to litigation and regulatory matters on a quarterly and annual basis and updates its established liabilities, disclosures and estimates of reasonably possible losses or range of loss based on such reviews.

The Company and certain of its insurance subsidiaries, as well as certain other insurance companies for which the Company has coinsured blocks of life insurance and annuity policies, are under audit for compliance with the unclaimed property laws of a number of states. The audits are being conducted on behalf of the treasury departments or unclaimed property administrators in such states. The focus of the audits is on whether there have been unreported deaths, maturities, or policies that have exceeded limiting age with respect to which death benefits or other payments under life insurance or annuity policies should be treated as unclaimed property that should be escheated to the state. The Company is presently unable to estimate the reasonably possible loss or range of loss that may result from the audits due to a number of factors, including uncertainty as to the legal theory or theories that may give rise to liability, the early stages of the audits being conducted, and uncertainty as to whether the Company or other companies are responsible for the liabilities, if any, arising in connection with certain co-insured policies. The Company will continue to monitor the matter for any developments that would make the loss contingency associated with the audits reasonably estimable.

The Company and certain of its insurance 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

The Company used its respective estimates for its annual 2018 and 2017 incomes in computing its effective income tax rates for the three months ended March 31, 2018 and 2017. The estimate of the annual 2018 income excluded unrealized gains and losses on equity securities due to an inability to forecast future gains and losses. The Company's effective tax rate related to continuing operations varied from the maximum federal income tax rates as follows:

	For The Three Months Ended March 31,
	2018		2017
Statutory federal income tax rate applied to pre-tax income	21.0	%	35.0	%
State income taxes	0.4		0.5
Investment income not subject to tax	(3.3	)	(3.4	)
Unrealized tax positions	—		0.1
Other	(1.4	)	0.5
	16.7	%	32.7	%

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 received an approximate $6.2 million net refund in the fourth quarter of 2017. The resulting net adjustment to the Company's current income taxes for the years 2003 through 2011 did not materially affect the Company or its effective tax rate.

In July 2016, the IRS proposed favorable and unfavorable adjustments to the Company's 2012 and 2013 reported taxable income. The Company agreed to these adjustments. The resulting settlement paid in September 2016 did not materially impact the Company or its effective tax rate.

There have been no material changes to the balance of unrecognized tax benefits, where the changes impact earnings, during the quarter ending March 31, 2018. The Company believes that in the next twelve months, none of the unrecognized tax benefits will be reduced.

In general, the Company is no longer subject to income tax examinations by taxing authorities for tax years that began before 2014. Furthermore, due to the aforementioned IRS adjustments to the Company's pre-2014 taxable income, the Company has amended certain of its 2003 through 2013 state income tax returns. Such amendments will cause such years to remain open, pending the states' acceptances of the returns.

During the year ended December 31, 2016, the Company entered into a reinsurance transaction. This transaction generated an operating loss on the Company’s consolidated 2016 U.S. income tax return. The Company partially carried back this loss and received refunds for substantially all of the U.S. income taxes it paid in 2014 and 2015 and expects to 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 March 31, 2018 and December 31, 2017.

In the tax year ended December 31, 2017, the Company recognized provisional impacts related to the revaluation of certain deferred tax assets under the Tax Reform Act under Staff Accounting Bulletin No. 118. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional regulatory guidance that may be issued, additional analysis, and resulting changes in interpretations and assumptions the Company has made. Any adjustments to these provisional amounts will be reported as a component of income tax expense (benefit) in the reporting period in which any such adjustments are determined. There are no such adjustments for the three months ended March 31, 2018. The accounting is expected to be complete by December 22, 2018.

OPERATING SEGMENTS

Segment Reporting [Abstract]

OPERATING SEGMENTS

OPERATINGSEGMENTS

The Company has several operating segments, each having a strategic focus. An operating segment is distinguished by products, channels of distribution, and/or other strategic distinctions. The Company periodically evaluates its operating segments and makes adjustments to its segment reporting as needed. A brief description of each segment follows.

• The Life Marketing segment markets fixed universal life (“UL”), indexed universal life ("IUL"), variable universal life (“VUL”), bank-owned life insurance (“BOLI”), and level premium term insurance (“traditional”) products on a national basis primarily through networks of independent insurance agents and brokers, broker-dealers, financial institutions, independent marketing organizations, and affinity groups.

• The Acquisitions segment focuses on acquiring, converting, and servicing policies and contracts acquired from other companies. The segment’s primary focus is on life insurance policies and annuity products that were sold to individuals. The level of the segment’s acquisition activity is predicated upon many factors, including available capital, operating capacity, potential return on capital, and market dynamics. Policies acquired through the Acquisitions segment are typically blocks of business where no new policies are being marketed. 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, GAP products, credit life and disability insurance, and other specialized ancillary products to protect consumers’ investments in automobiles and recreational vehicles. GAP products are designed to cover the difference between the scheduled loan pay-off amount and an asset’s actual cash value in the case of a total loss. Each type of specialized ancillary product protects against damage or other loss to a particular aspect of the underlying asset.

• The Corporate and Other segment primarily consists of net investment income on assets supporting our equity capital, unallocated corporate overhead and expenses not attributable to the segments above. This segment includes earnings from several non-strategic or runoff lines of business, various financing and investment-related transactions, and the operations of several small subsidiaries.

 The Company's management and Board of Directors analyzes and assesses the operating performance of each segment using "pre-tax adjusted operating income (loss)" and "after-tax adjusted operating income (loss)". Consistent with GAAP accounting guidance for segment reporting, pre-tax adjusted operating income (loss) is the Company's measure of segment performance. Pre-tax adjusted operating income (loss) is calculated by adjusting "income (loss) before income tax", by excluding the following items:

• realized gains and losses on investments and derivatives,

• changes in the GLWB embedded derivatives exclusive of the portion attributable to the economic cost of the GLWB,

• actual GLWB incurred claims, and

• the amortization of deferred acquisition costs ("DAC"), value of business acquired ("VOBA"), and certain policy liabilities that is impacted by the exclusion of these items.

The items excluded from adjusted operating income (loss) are important to understanding the overall results of operations. Pre-tax adjusted operating income (loss) and after-tax adjusted operating income (loss) are not substitutes for income before income taxes or net income (loss), respectively. These measures may not be comparable to similarly titled measures reported by other companies. The Company believes that pre-tax and after-tax adjusted operating income (loss) enhances management's and the Board of Directors' understanding of the ongoing operations, the underlying profitability of each segment, and helps facilitate the allocation of resources.

After-tax adjusted operating income (loss) is derived from pre-tax adjusted operating income (loss) with the inclusion of income tax expense or benefits associated with pre-tax adjusted operating income. Income tax expense or benefits is allocated to the items excluded from pre-tax adjusted operating income (loss) at the statutory federal income tax rate for the associated period. For periods ending on and prior to December 31, 2017, a rate of 35% was used. Beginning in 2018, a statutory federal income tax rate of 21% will be used to allocate income tax expense or benefits to items excluded from pre-tax adjusted operating income (loss). Income tax expense or benefits allocated to after-tax adjusted operating income (loss) can vary period to period based on changes in the Company's effective income tax rate.

In determining the components of the pre-tax adjusted operating income (loss) for each segment, premiums and policy fees, other income, benefits and settlement expenses, and amortization of DAC and VOBA are attributed directly to each operating segment. Net investment income is allocated based on directly related assets required for transacting the business of that segment. Realized investment gains (losses) and other operating expenses are allocated to the segments in a manner that most appropriately reflects the operations of that segment. Investments and other assets are allocated based on statutory policy liabilities net of associated statutory policy assets, while DAC/VOBA and goodwill are shown in the segments to which they are attributable.

There were no significant intersegment transactions during the three months ended March 31, 2018 and 2017.

The following tables present a summary of results and reconciles pre-tax adjusted operating income (loss) to consolidated income before income tax and net income:

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

SUBSEQUENT EVENTS

The Company has evaluated the effects of events subsequent to March 31, 2018, and through the date we filed our consolidated condensed financial statements with the United States Securities and Exchange Commission. All accounting and disclosure requirements related to subsequent events are included in our consolidated condensed financial statements.

On May 1, 2018, The Lincoln National Life Insurance Company ("Lincoln Life") completed its previously announced acquisition (the “Closing”) of Liberty Mutual Group Inc.’s (“Liberty Mutual”) Group Benefits Business and Individual Life and Annuity Business (the “Life Business”) through the acquisition of all of the issued and outstanding capital stock of Liberty Life Assurance Company of Boston (“Liberty”). In connection with the Closing and pursuant to the Master Transaction Agreement, dated January 18, 2018 (the “Master Transaction Agreement”), previously reported in the Company's Current Report on Form 8-K filed on January 23, 2018, the Company, a wholly owned subsidiary of PLC, and Protective Life and Annuity Insurance Company (“PLAIC”), a wholly owned subsidiary of the Company, entered into reinsurance agreements (the “Reinsurance Agreements”) and related ancillary documents (including administrative services agreements and transition services agreements) providing for the reinsurance and administration of the Life Business. 

Pursuant to the Reinsurance Agreements, Liberty ceded to the Company and PLAIC the insurance policies related to the Life Business on a 100% coinsurance basis. The aggregate ceding commission for the reinsurance of the Life Business was $422.9 million. All policies issued in states other than New York were ceded to the Company under a reinsurance agreement between Liberty and the Company, and all policies issued in New York were ceded to PLAIC under a reinsurance agreement between Liberty and PLAIC.  The aggregate statutory reserves of Liberty ceded to the Company and PLAIC as of the closing of the Transaction were approximately $13.3 billion, which amount was based on initial estimates and is subject to adjustment following the Closing.  Pursuant to the terms of the Reinsurance Agreements, each of the Company and PLAIC are required to maintain assets in trust for the benefit of Liberty to secure their respective obligations to Liberty under the Reinsurance Agreements. The trust accounts were initially funded by each of the Company and PLAIC principally with the investment assets that were received from Liberty. Additionally, the Company and PLAIC have each agreed to provide, on behalf of Liberty, administration and policyholder servicing of the Life Business reinsured by it pursuant to administrative services agreements between Liberty and each of the Company and PLAIC.

On May 3, 2018, PLC and the Company (together with PLC, the “Borrowers”) entered into the First Amendment (the “First Amendment”) to the Amended and Restated Credit Agreement dated February 2, 2015 (the “Credit Agreement”) with the several lenders from time to time a party thereto (collectively, the “Lenders”) and with Regions Bank in its capacity as Administrative Agent for the Lenders (the “Administrative Agent”). The Credit Agreement, as amended by the First Amendment, continues to provide for a $1 billion, five-year unsecured revolving credit facility (the “Credit Facility”), including a $500 million sublimit for the potential issuance of letters of credit and a $50 million sublimit for swingline advances. Borrowings made available under the Credit Facility may be used for general corporate purposes, including the refinancing of indebtedness. The First Amendment, among other things, extends the commitment termination date and final maturity date under the Credit Agreement from February 2, 2020 to May 3, 2023, allows the Borrowers in certain circumstances to request that the commitment amount under the Credit Facility be increased to a maximum amount of $1.5 billion (increased from the maximum $1.25 billion amount originally provided in the Credit Agreement), and changes the reference dates and base amounts used to calculate the minimum Adjusted Consolidated Net Worth that PLC is required to maintain under the Credit Agreement.

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. 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 months ended March 31, 2018, are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2018. 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, 2017.

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.

Insurance Revenue

Property and casualty insurance products include service contract business, surety bonds, and guaranteed asset protection ("GAP"). Premiums and fees associated with service contracts and GAP products are recognized based on expected claim patterns. For all other products, premiums are generally recognized over the terms of the contract on a pro-rata basis. Commissions and fee income associated with other products are recognized as earned when the related services are provided to the customer. Unearned premium reserves are maintained for the portion of the premiums that is related to the unexpired period of the policy. Benefit reserves are recorded when insured events occur.

Reserves

Benefit reserves include case basis reserves for known but unpaid claims as of the balance sheet date as well as incurred but not reported ("IBNR") reserves for claims where the insured event has occurred but has not been reported to the Company as of the balance sheet date. The case basis reserves and IBNR are calculated based on historical experience and on assumptions relating to claim severity and frequency, the level of used vehicle prices, and other factors. These assumptions are modified as necessary to reflect anticipated trends.

Accounting Pronouncements Recently Adopted and Not Yet Adopted

Accounting Pronouncements Recently 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 adopted this Update using the modified retrospective approach via a cumulative effect adjustment to retained earnings as of January 1, 2018. The amendments in the Update, along with clarifying updates issued subsequent to ASU 2014-09, impacted certain revenues associated with the Company's Asset Protection products. The lines of business to which the revised guidance applies are not material to the Company’s financial statements. In consideration of the amendments in this Update, the Company revised its recognition pattern for administrative fees associated with certain vehicle service and GAP products. Previously, these fees were recognized based on the work effort involved in satisfying the Company’s contract obligations. The Company will recognize these fees on a claims occurrence basis in future periods. To reflect this change in accounting principle, the Company recorded a cumulative effect adjustment as of January 1, 2018 that resulted in a decrease in retained earnings of $88.6 million. See above for additional discussion.

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 were applied on a modified retrospective basis. The Company recorded a cumulative-effect adjustment at the date of adoption, January 1, 2018, transferring unrealized gains and losses on available-for-sale equity securities to retained earnings from accumulated other comprehensive income. The impact of this adjustment, net of income tax, resulted in a $10.6 million increase to retained earnings and a corresponding decrease to accumulated other comprehensive income, resulting in no net impact to consolidated shareowner's equity. The Company has updated its disclosures in Note 4, Investment Operations and Note 5, Fair Value of Financial Instruments in accordance with the ASU.

ASU No. 2016-15 - Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update are intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Specific transactions addressed in the new guidance include:Debt prepayment/extinguishment costs, contingent consideration payments, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investments. The Update does not introduce any new accounting or financial reporting requirements, and is effective for annual and interim periods beginning after December 15, 2017 using the retrospective method. There was no financial impact.

ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Task Force). The amendments in this update provide guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows, thereby reducing diversity in practice related to the presentation of these amounts. The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. There was no impact to the Company on adoption.

ASU No. 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of this update is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the Update provide a specific test by which an entity may determine whether an acquisition involves a set of assets or a business. The amendments in the Update are to be applied prospectively for periods beginning after December 15, 2017. The Company has reviewed the revised requirements, and does not anticipate that the changes will impact its policies or recent conclusions related to its acquisition activities.

ASU No. 2017-07 - Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The amendments in this update require entities to disaggregate the current-service-cost component from other components of net benefit cost and present it with other current compensation costs in the income statement. The other components of net benefit cost must be presented outside of income from operations if that subtotal is presented. In addition, the Update requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. As provided for in the ASU, the Company expects to apply the provisions of the statement retrospectively for components of net periodic pension costs and prospectively for capitalization of the service costs component of net periodic costs and net periodic postretirement benefits. The Update did not impact the Company’s financial position, results of operations, or current disclosures.

Accounting Pronouncements Not Yet Adopted

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. 2017-08 - Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update require that premiums on callable debt securities be amortized to the first call date. This is a change from current guidance, under which premiums are amortized to the maturity date of the security. The amendments are effective for annual and interim periods beginning after December 31, 2018, and early adoption is permitted. Transition will be through a modified retrospective approach in which the cumulative effect of application is recorded to retained earnings at the beginning of the annual period in which an entity adopts the revised guidance. The Company is currently reviewing its systems and processes to determine the financial and operational impact of implementing the Update, as well as to determine whether early adoption of the revised guidance is practicable.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update are designed to permit hedge accounting to be applied to a broader range of hedging strategies as well as to more closely align hedge accounting and risk management objectives. Specific provisions include requiring changes in the fair value of a hedging instrument be recorded in the same income statement line as the hedged item when it affects earnings. In addition, after a hedge has initially qualified as an effective hedge the Update permits the use of a qualitative hedge effectiveness test in subsequent periods. The amendments in this Update are effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact this standard will have on its operations and financial results.
