NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(Dollar amounts in thousands, except per share data)

Note 1—Significant Accounting Policies

Basis of Presentation: The accompanying condensed consolidated financial statements of Torchmark Corporation (Torchmark or alternatively, the Company) have been prepared in accordance with the instructions to Form 10-Q. Therefore, they do not include all of the annual disclosures required by accounting principles generally accepted in the United States of America (GAAP). However, in the opinion of management, these statements include all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial position at September 30, 2017, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended September 30, 2017 and 2016. The interim period condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements that are included in the Form 10-K filed with the Securities Exchange Commission (SEC) on February 27, 2017.

Note 2—New Accounting Standards

Accounting Pronouncements Not Yet Adopted

ASU 2016-01: In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which primarily revises the classification and measurement of certain equity investments such that they will be measured at fair value through net income. Additionally, it eliminates the cost method for partnerships and joint ventures and requires these types of investments to be accounted for under the fair value through net income method or equity method. Lastly, the guidance will require certain disclosures associated with fair value of financial instruments. This standard will become effective for the Company beginning January 1, 2018. The adoption will not have a significant impact on the financial statements as we have limited ownership in equity investments and partnerships, representing less than 1% of total invested assets.

ASU 2016-02: In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires all lessees to report a right-of-use asset and a lease liability for leases with a term life greater than 12 months. Operating and financing leases will be recognized on the balance sheet going forward. Additional qualitative and quantitative disclosures will be required. This standard will become effective for the Company beginning January 1, 2019 and will require recognizing and measuring leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The Company does not expect the adoption to have a significant impact on the financial statements. Refer to the 2016 Form 10-K Note 15—Commitments and Contingencies for consideration of the noncancellable operating lease commitments. The Company does not have any lessor commitments.

ASU 2016-13: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments as well as to change the loss impairment methodology for available-for-sale debt securities. This standard will become effective on January 1, 2020. The applicable section of the standard related to debt securities requires a prospective transition. The Company does not expect the adoption to have a significant impact on the financial statements as we have limited credit losses with respect to our available-for-sale portfolio.

ASU 2016-15: In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments to provide uniformity in the classification of cash receipts and payments recorded in the statement of cash flows including debt prepayment or debt extinguishment costs, settlement of zero-coupon bonds, and proceeds from the settlement of insurance claims. This standard will become effective on January 1, 2018 and will not have a significant impact on the financial statements.

ASU 2016-16: In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other Than Inventory. This guidance was issued to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory by allowing the immediate recognition of the current and deferred income tax effects. Current guidance prohibits the recognition of current and deferred income taxes for an intra-entity transfer until the asset has been sold to an outside party. This new guidance should be applied on a modified retrospective

approach and will become effective on January 1, 2018. This adoption will not have a significant impact on the financial statements.

ASU 2017-04:In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This guidance was issued to simplify the subsequent measurement of goodwill through the elimination of Step 2 from the goodwill impairment test which required a hypothetical purchase price allocation. It will become effective on January 1, 2020 and should be applied on a prospective basis. This adoption will not have a significant impact on the financial statements.

ASU 2017-07: In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance was issued to simplify the reporting of pension costs by disaggregating the service-cost component from the other components of net benefit costs and reporting it separately on the income statement. The service-cost component is the only component of net benefit cost that will be eligible for capitalization. The guidance will become effective on January 1, 2018 with a retrospective transition method for separation of net benefit costs and a prospective transition method for the capitalization of service costs. The Company does not expect the adoption to have a significant impact on the financial statements as the change in pension capitalization should be less than 1% of Total Benefits and Expenses on the Consolidated Statement of Operations for the year.

ASU 2017-08: In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance was issued to shorten the amortization period for certain callable debt securities held at a premium. The guidance requires the premium to be amortized to the earliest call date. It will become effective on January 1, 2019 with early adoption permitted, including during interim periods. The adoption is to be applied on a modified retrospective basis through an adjustment to retained earnings. This adoption will not have a significant impact on the financial statements.

ASU 2017-09: In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. This guidance was issued to provide clarity and guidance regarding changes to the terms or conditions of a share-based payment award that requires an entity to apply modification accounting. It will become effective on January 1, 2018 with early adoption permitted, including adoption in any interim periods. The Company does not expect the adoption to have a significant impact on the financial statements as modifications to stock compensation are infrequent.

Other-Than-Temporary Impairments:

In accordance with the other-than-temporary impairment (OTTI) policy, the Company evaluated its fixed maturities available for sale in an unrealized loss position to determine if there was any impairment for the quarter. Gross unrealized losses may fluctuate quarter over quarter due to adverse factors in the market that affect our holdings, such as changes in the interest rates or credit spreads. While the Company holds securities that may be in an unrealized loss position from time to time, Torchmark has the ability and intent to hold these investments to recovery. Additionally, Torchmark does not expect to be required to sell any of its securities due to the strong cash flows generated by its insurance operations.

For the nine months ended September 30, 2017, the Company recorded $245 thousand ($159 thousand, net of tax) in OTTI. For the comparable period in 2016, the Company concluded that there were no other-than-temporary impairments.

Unrealized Loss Analysis:

The following table discloses information about fixed maturities available for sale in an unrealized loss position.

	Less than Twelve Months	Twelve Months or Longer	Total
Number of issues (CUSIP numbers) held:
As of September 30, 2017	151	109	260
As of December 31, 2016	407	94	501

Torchmark’s entire fixed maturity portfolio consisted of 1,514 issues at September 30, 2017 and 1,565 issues at December 31, 2016. The weighted average quality rating of all unrealized loss positions as of September 30, 2017 was BBB compared with BBB+ as of December 31, 2016.

Note 5—Discontinued Operations

At December 31, 2015, Torchmark met the criteria to account for its Medicare Part D Prescription Drug Plan business as a discontinued operation. Historically, the business was a reportable segment. Effective July 1, 2016, Torchmark sold its Medicare Part D Prescription Drug Plan business to an unaffiliated third party.

The sale resulted in a net gain of $1.8 million ($1.2 million net of tax) in 2016. The operating results from discontinued operations are reflected in income for the nine months ended September 30, 2017. The remaining assets and liabilities reflected on the Torchmark balance sheet related to discontinued operations are receivables and payables associated with the 2016 and prior plan years that are expected to be settled in the ordinary course of business during 2017 and 2018.

The net assets related to discontinued operations at September 30, 2017 and December 31, 2016 were as follows:

	September 30, 2017		December 31, 2016
Assets:
Due premiums	$	3,945	$	8,840
Other receivables(1)	64,627		118,692

Note 6—Commitments and Contingencies

Litigation:

Torchmark and its subsidiaries, in common with the insurance industry in general, are subject to litigation, involving various matters where we are either the defendant or the plaintiff. Torchmark subsidiaries are also currently the subject of audits regarding the identification, reporting and escheatment of unclaimed property arising from life insurance policies and a limited number of annuity contracts. In each of these matters, based upon information presently available, management does not believe that such litigation or audits will have a material adverse effect on Torchmark’s financial condition, future operating results or liquidity.

As previously reported, litigation was filed on February 10, 2015 against Torchmark subsidiary, Globe Life And Accident Insurance Company (Globe) in Oklahoma County, Oklahoma District Court (Proctor v. Globe Life And Accident Insurance Company, Case No. CJ-2015-838) asserting claims for breach of the implied covenants of good faith and fair dealing and for false representation, deceit and conversion in connection with Globe’s denial of plaintiff’s claim on a life insurance policy for non-payment of premium. Plaintiff, who had alleged that Globe had improperly retained 12 monthly premium payments on a policy that was treated as lapsed or not returned to in-force status, seeks actual and punitive damages, prejudgment interest, attorney fees, costs and other relief. Plaintiff subsequently amended his

complaint to add allegations of conversion and civil theft on behalf of a purported class of Globe’s U.S. policyholders who had paid premiums retained by Globe when their policies were lapsed and not reinstated at the time of the premium payments. Globe removed the case to the U.S. District Court for the Western District of Oklahoma (Case No. 15-CV-0070-M) on July 10, 2015 and filed a Motion to Dismiss on July 17, 2015. The Court denied plaintiff’s Motion to Remand back to state court on October 26, 2015, but allowed the plaintiff to amend the complaint to assert a putative class action in federal court. Plaintiff filed a Motion for Class Certification on September 23, 2016. Globe filed a Response in Opposition on November 4, 2016. The Court denied plaintiff’s Motion for Class Certification on August 18, 2017.

With respect to current litigation, at this time management believes that the possibility of a material judgment adverse to Torchmark is remote, and no estimate of range can be made for loss contingencies that are at least reasonably possible but not accrued.

Guaranty Fund Assessment:

In 2017, the Commonwealth Court of Pennsylvania issued orders placing Penn Treaty Network America Insurance Company (Penn Treaty) and affiliate American Network Insurance Company (ANIC) in liquidation due to financial difficulties. In such instances, the various state guaranty fund associations employ funding mechanisms, through assessments to their member companies, to cover the obligations of the insolvent entities. Consequently, the Company continues to receive guaranty fund assessments from the state associations related to these companies. The Company has projected its share of the ultimate assessments from these insolvencies based on assumptions about future events and its market share of premiums by state. The total estimated assessment for Torchmark's subsidiaries is approximately$10 millionof which$1.4 million is estimated to be unrecoverable. We are anticipating the remaining amount of the assessments to be recovered through premium tax credits.

(1) Supplemental executive retirement plan (SERP).

During the nine months ended September 30, 2017, the Company made $19 million in cash contributions to the qualified pension plans. Torchmark will not make any additional cash contributions in 2017.

With respect to the Company’s active nonqualified noncontributory SERP, life insurance policies on the lives of plan participants have been established with an unaffiliated carrier to provide for a portion of the Company’s obligations under the plan. These policies along with investments deposited with an unaffiliated trustee were previously placed in a Rabbi Trust to provide for the payment of the plan obligations. At September 30, 2017, the combined value of the insurance policies and investments in the Rabbi Trust to support plan liabilities were $94 million, compared with $86 million at December 31, 2016. Since this plan is nonqualified and therefore is treated as unfunded, the values of the insurance policies and investments are recorded as Other assets in the Condensed Consolidated Balance Sheets and are not included in the chart of plan assets above.

Note 10—Business Segments

Torchmark's reportable segments are based on the insurance product lines it markets and administers: life insurance, health insurance, and annuities. These major product lines are set out as reportable segments because of the common characteristics of products within these categories, comparability of margins, and the similarity in regulatory environment and management techniques. Torchmark's chief operating decision makers evaluate the overall performance of the operations of the Company in accordance with these segments.

Management’s measure of profitability for each insurance segment is insurance underwriting margin, which is underwriting income before other income and insurance administrative expenses. It represents the profit margin on insurance products before administrative expenses, and is calculated by deducting net policy obligations (claims incurred and change in reserves), commissions and other acquisition expenses from premium revenue. Torchmark further views the profitability of each insurance product segment by the marketing groups that distribute the products of that segment: direct response, independent agencies, or captive agencies.

Note 10—Business Segments (continued)

Torchmark’s management prefers to evaluate the performance of its underwriting and investment activities separately, rather than allocating investment income to the underwriting results. As such, the investment function is presented as a stand-alone segment. The investment segment includes the management of the investment portfolio, debt, and cash flow. Management’s measure of profitability for this segment is excess investment income, which is the income earned on the investment portfolio less the required interest on net policy liabilities and financing costs. Financing costs include the interest on Torchmark’s debt. Other income and insurance administrative expense are classified in a separate Other segment.

The majority of the Company’s required interest on net policy liabilities (benefit reserves less the deferred acquisition cost asset) is not credited to policyholder accounts. Instead, it is an actuarial assumption for discounting cash flows in the computation of benefit reserves and the amortization of the deferred acquisition cost asset. Investment income required to fund the required interest on net policy liabilities is removed from the investment segment and applied to the insurance segments to eliminate the effect of the required interest from the insurance segments. As a result, the investment segment measures net investment income against the required interest on net policy liabilities and financing costs, while the insurance segments simply measure premiums against net policy benefits and expenses. Management believes this presentation facilitates a more meaningful analysis of the Company’s underwriting and investment performance as the underwriting results are based on premiums, claims, and expenses and are not affected by unanticipated fluctuations in investment yields.

As noted, Torchmark’s “core operations” are insurance and investment management. The insurance segments issue policies for which premiums are collected for the eventual payment of policy benefits. In addition to policy benefits, operating expenses are incurred including acquisition costs, administrative expenses, and taxes. Because life and health contracts can be long term, premium receipts in excess of current expenses are invested. Investment activities, conducted by the investment segment, focus on seeking quality investments with a yield and term appropriate to support the insurance product obligations. These investments generally consist of fixed maturities, and, over the long term, the expected yields are taken into account when setting insurance premium rates and product profitability expectations. As a result, fixed maturities are generally held for long periods to support the liabilities, and Torchmark generally expects to hold investments until maturity. However, dispositions of investments occur from time to time, generally for reasons such as credit concerns, calls by issuers, or other factors.

Since Torchmark does not actively trade investments, realized gains and losses from the disposition and write down of investments are generally incidental to operations and are not considered a material factor in insurance pricing or product profitability. While from time to time these realized gains and losses could be significant to net income in the period in which they occur, they generally have a limited effect on the yield of the total investment portfolio. Further, because the proceeds of the disposals are reinvested in the portfolio, the disposals have little effect on the size of the portfolio and the income from the reinvestments is included in net investment income. Therefore, management removes realized investment gains and losses from results of core operations when evaluating the performance of the Company. For this reason, these gains and losses are excluded from Torchmark’s operating segments.

Torchmark accounts for its stock options and restricted stock under current accounting guidance requiring stock options and stock grants to be expensed based on fair value at the time of grant. Management considers stock compensation expense to be an expense of the Parent Company. Therefore, stock compensation expense is treated as a corporate expense in Torchmark’s segment analysis.

As discussed in Note 6—Commitments and Contingencies, the Company received an assessment from various state guaranty fund associations for the liquidation of Penn Treaty and its affiliate. The total estimated assessment for Torchmark's subsidiaries is approximately$10 millionof which$1.4 million is estimated to be unrecoverable. We are anticipating the remaining amount of the assessments to be recovered through premium tax credits. The assessment expenses were considered a non-operational event and therefore were excluded from the core underwriting operations of the Company.

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

Results of Operations

Summary of Operations. Torchmark’s operations are segmented into its insurance underwriting and investment operations as described in Note 10—Business Segmentsin the Notes to the Condensed Consolidated Financial Statements. The measures of profitability are useful in evaluating the performance of the segments and the marketing groups within each insurance segment because each of our distribution channels operates in a niche market. Insurance underwriting margin consists of premium less policy obligations, commissions and other acquisition expenses. These measures enable management to view period-to-period trends, and to make informed decisions regarding future courses of action.

The tables in Note 10 demonstrate how the measures of profitability are determined. Those tables also reconcile our revenues and expenses by segment to major income statement line items for the three month and nine month periods ended September 30, 2017 and 2016. Additionally, a table in that note, Analysis of Profitability by Segment, provides a summary of profitability measures that demonstrates year-to-year comparability and reconciles those measures to our net income. That summary represents our overall operations in the manner that management views the business, and is a basis of the following highlights discussion.

We use three statistical measures as indicators of future premium growth: “annualized premium in force", "net sales", and “first-year collected premium.” Annualized premium in force is defined as the premium income that would be received over the following twelve months at any given date on all active policies if those policies remain in force throughout the twelve month period. Annualized premium in force is an indicator of potential growth in premium revenue. Net sales is defined as annualized premium issued⁽¹⁾, net of cancellations in the first thirty days after issue, except for Globe Life Direct Response, where net sales is annualized premium issued at the time the first full premium is paid after any introductory offer has expired. Although lapses and terminations will occur, we believe that net sales is a useful indicator of the rate of acceleration of premium growth. First-year collected premium is the premium collected during the reporting period for all policies in their first policy year. First-year collected premium takes lapses into account in the first policy year when lapses are more likely to occur, and thus is a useful indicator of how much new premium is expected to be added to premium income in the future.

A discussion of operations by each segment follows later in this report. These discussions compare the first nine months of 2017 with the same period of 2016, unless otherwise noted. The following discussions are presented in the manner we view our operations, as described in Note 10.

(1) Annualized premium issued is the gross premium that would be received during the policies’ first year in force, assuming that none of the policies lapsed or terminated.

Highlights, comparing the first nine months of 2017 with the first nine months of 2016.

Net income per diluted common share increased6% to $3.58 from $3.38. Included in net income were after-tax realized gains of $6.2 million in 2017compared with gains of $5.1 million for the same period in2016. Realized gains and losses are presented more fully under the caption Realized Gains and Losses in this report. Net operating income from continuing operations is the consolidated total of segment profits after tax and as such is considered a non-GAAP measure. Net operating income from continuing operations increased 4% or $17 million to $427 million for the nine months ended September 30,2017 compared with $410 million for the same 2016 period.

Total premium income rose5% in 2017 to $2.5 billion. Total net sales increased 2% to $420 million, when compared with the same period in 2016. First-year collected premium was $339 million for the 2017 period, compared with $340 million for the 2016 period.

Life insurance premium income grew5% to $1.7 billion. Life net sales increased1% when compared with the same period in 2016. First-year collected life premium grew1% during the first nine months of 2017 to $239 million over the same period in 2016. Life underwriting margin as a percentage of premium was flat at26%. Underwriting income increased3% to $444 million when compared with the same period in 2016.

Health insurance premium income increased3% to $731 million over the prior year total of $710 million. Health net sales rose6% to $104 million for the nine month period. First-year collected health premium fell4% to $100 million. Health margins increased to 23% from 22% a year earlier. Underwriting income increased5% to $164 million for the first nine months of 2017.

Insurance administrative expenses were up6.6% in 2017 when compared with the prior year period. These expenses were 6.3% as a percentage of premium during the first nine months of 2017 compared with 6.2% a year earlier. The increase in administrative expenses was primarily due to an increase in other employee costs and investments in information technology.

Excess investment income is defined as net investment income less the required interest on net policy liabilities and the interest cost associated with capital funding or “financing costs”. Excess investment income per diluted common share is an important measure to management. Refer to the Excess Investment Income section of this report for further details. Excess investment income per common share increased13% in 2017 to $1.52 from $1.35 in the same period last year, while the dollar amount of excess investment income increased9% to $182 million. Net investment income rose$34 million or 6% to $635 million in 2017, below the 7% growth in our average investment portfolio at amortized cost. The average effective yield earned on the fixed maturity portfolio, which represented 96% of our investments at amortized cost, decreased to 5.68% in the 2017 period from 5.80% in the prior period. Required interest rose5% or $18 million to $390 million, in line with the growth in average net policy liabilities. Financing costs were flat at$63 million. Please refer to the discussion under Capital Resources for more information on debt and interest expense.

In the first nine months of 2017, we invested new money in fixed maturity securities at an effective annual yield of 4.74%, compared with 4.73% in the same period of 2016. These new investments had an average rating of BBB+ and an average life to maturity of twenty-four years. Approximately 96% of the fixed-maturity portfolio at amortized cost was investment grade at September 30, 2017. Cash and short-term investments were $154 million at that date, compared with $148 million at December 31, 2016.

The net unrealized gain position in our fixed maturity portfolio grew from $1.1 billion at December 31, 2016 to $1.7 billion at September 30, 2017 due primarily to changes in market interest rates.

28

Share Repurchases. We have an on-going share repurchase program which began in 1986 that is reviewed quarterly and is reaffirmed by the Board of Directors on an annual basis. The program was reaffirmed on August 7, 2017. With no specified authorization amount, we determine the amount of repurchases based on the amount of our excess cash flow, general market conditions, and other alternative uses. These purchases are made at the Parent Company with excess cash flow. Excess cash flow is primarily made up of cash received from the insurance subsidiaries less dividends paid to shareholders and interest paid on our debt. See further discussion in the Capital Resources section below. Share purchases are also made with the proceeds from option exercises by current and former employees in order to reduce dilution. The following chart summarizes share purchases for the nine month periods ended September 30, 2017 and 2016.

A detailed discussion of our operations by component segment follows.

Life insurance, comparing the first nine months of 2017 with the first nine months of 2016. Life insurance is our predominant segment, representing 70% of premium income and 72% of insurance underwriting margin in the first nine months of 2017. In addition, investments supporting the reserves for life business generate the majority of excess investment income attributable to the investment segment.

The American Income Exclusive Agency has historically marketed primarily to members of labor unions. While labor unions are still the core market for this agency, American Income has diversified in recent years by focusing heavily on referrals and other affinity groups to help ensure sustainable growth. This agency is the largest contributor to life premium and underwriting margin of any distribution channel. This group produced premium income of $741 million, an increase of9%. First-year collected premium was $136 million, an increase of5%. Net sales rose6% to $167 million. Sales growth in our exclusive agencies is generally dependent on growth in the size of the agency force. The American Income Exclusive Agency's average agent count increased5% to 6,962 for the nine months ended September 30, 2017, compared with 6,603 for the same period in 2016. As is the case with all Torchmark agencies, the average agent count is based on the actual count at the end of each week during the period. The American Income Exclusive Agency has been focusing on growing and strengthening middle management to support sustainable growth of the agency force. To accomplish this, the agency has placed an increased emphasis on training and financial incentives that appropriately reward agents at all levels for helping develop and train its agents. These programs are designed to provide each agent, from new recruits to top level managers, coaching and instruction specifically designed for their level of experience and responsibility. We are also making considerable investments in information technology in support of the agency.

The Globe Life Direct Response Unit offers adult and juvenile life insurance through a variety of direct-to-consumer marketing approaches, which include direct mailings, insert media, and electronic media. These different approaches support and complement one another in the unit’s efforts to reach the consumer. The Globe Life Direct Response channel’s growth over the years has been fueled by constant innovation. In recent years, electronic media production has grown rapidly as management has increased marketing activities related to internet and mobile technology, and has focused on driving traffic to an inbound call center. We continually introduce new initiatives in this unit in an attempt to increase response rates.

While the juvenile market is an important source of sales, it also is a vehicle to reach the parents and grandparents of juvenile policyholders, who are more likely to respond favorably to a Globe Life Direct Response solicitation for life coverage on themselves than is the general adult population. Also, both juvenile policyholders and their parents are low acquisition-cost targets for sales of additional coverage over time.

Globe Life Direct Response’s life premium income rose4% to $614 million, representing 35% of Torchmark’s total life premium in the first nine months of 2017. Net sales of $107 million for this group decreased8%. First-year collected premium decreased6% to $71 million. The underwriting margin, as a percent of premium, was 15.6%, up from 15.2% in the year-ago quarter. While higher claims will cause the underwriting margin to be lower for the full year 2017 as compared with 2016, the increase in the quarter was fully in line with our expectations. The sales and first-year collected premium declines were expected as we continue to refine our marketing efforts in a manner intended to optimize underwriting profits.

The Liberty National Exclusive Agency markets individual and group life insurance to middle-income customers. Life premium income for this agency was $206 million in the first nine months of 2017 compared with $203 million for the same period in 2016. First-year collected premium increased13% to $25 million. Net sales for the Liberty National Agency increased16% to $35 million. The increases in first-year collected premium and net sales are the largest percentage increases of any of Torchmark's life distribution channels.

The Liberty National average agent count increased17% to 1,985 for the nine months ended September 30, 2017 compared with 1,693 for the same period in 2016. We continue to execute our long term plan to grow this agency through expansion from small town markets in the southeast to more densely populated areas with larger pools of potential agent recruits and customers. Expansion of this agency’s presence into more heavily populated, less-penetrated areas will help create long term agency growth. Additionally, our prospecting training program has helped to improve the ability of agents to develop new worksite marketing business.

The Other Agencies distribution channels primarily include independent agencies selling predominantly life insurance. The Other Agencies contributed $165 million of life premium income, or 10% of Torchmark’s total in the first nine months of 2017, but contributed only 2% of net sales for the period.

31

Health insurance, comparing the first nine months of 2017 with the first nine months of 2016. Health insurance sold by Torchmark includes primarily Medicare Supplement insurance, critical illness coverage, accident coverage, and other limited-benefit supplemental health products. In this analysis, all health coverage plans other than Medicare Supplement are classified as limited-benefit plans.

Health premium accounted for 30% of our total premium in the 2017 period. Health underwriting margin accounted for 27% of total underwriting margin, reflective of the lower underwriting margin as a percentage of premium for health compared with life insurance. As noted under the caption Life Insurance, we have emphasized life insurance sales relative to health, due to life’s superior profitability and its greater contribution to excess investment income.

The following table presents underwriting margin data for health insurance.

A discussion of health operations by distribution channel follows:

The UA Independent Agency consists of independent agencies appointed with Torchmark who may also sell for other companies. The UA Independent Agency was Torchmark’s largest health agency in terms of health premium income. Premium income was $273 million, representing 37% of Torchmark’s total health premium. Net sales were $33 million, or 32% of Torchmark’s health sales. This agency primarily produces Medicare Supplement insurance, with Medicare Supplement premium income of $264 million. The UA Independent Agency represents approximately 74% of all Torchmark Medicare Supplement premium and 90% of Medicare Supplement net sales. Medicare Supplement premium in this agency rose3%. Total health premium increased2%. Net sales of the Medicare Supplement product increased4% in 2017 as a result of an increase in group sales. First-year collected health premium fell18% to $40 million, as a result of a high level of group sales in the fourth quarter of 2015 that positively affected the 2016 first-year collected premium.

The Family Heritage Agency primarily markets limited-benefit supplemental health insurance in non-urban areas. Most of their policies include a cash-back feature, such as a return of premium whereby any excess of premiums over claims paid is returned to the policyholder at the end of a specified period stated within the insurance policy. Management expects to grow this agency by continuing the incorporation of Torchmark’s agent recruiting programs. The Family Heritage Agency contributed $42 million and $38 million in net sales in the nine months of 2017 and 2016, respectively.

35

Health premium income was $188 million for the nine month period of 2017, representing 26% of Torchmark’s health premium compared with $176 million or 25% of health premium in the prior year period. The average agent count was 984 for the nine months ended September 30, 2017 compared with 915 for the same period in 2016, an increase of8%.

The Liberty National Exclusive Agency represented 20% of all Torchmark health premium income at $148 million in the nine months of 2017. The Liberty Agency markets limited-benefit health supplemental products consisting primarily of critical illness insurance. Much of Liberty’s health business is now generated through worksite marketing targeting small businesses of 10 to 25 employees. In 2017, health premium income in the Liberty Agency declined$4 million to $148 million from prior year premium. Liberty’s health premium decline is primarily due to its declining Medicare Supplement block as we are no longer selling these products from this agency.

Other distribution. Certain of our other distribution channels market health products, although their main emphasis is on life insurance. On a combined basis, they accounted for 17% of health premium in the 2017 period. The American Income Exclusive Agency primarily markets accident plans. The Direct Response unit markets primarily Medicare Supplements to employer or union-sponsored groups. Direct Response added $4 million of Medicare Supplement net sales in 2017.

Annuities. Annuities represent an insignificant part of our business and are not expected to be an important part of our marketing strategy going forward.

Operating expenses, comparing the first nine months of 2017 with the first nine months of 2016. Operating expenses consist of insurance administrative expenses and Parent Company expenses. Also included is stock compensation expense, which is viewed by us as Parent Company expense. Insurance administrative expenses relate to premium income for a given period; therefore, we measure those expenses as a percentage of premium income. Total expenses are measured as a percentage of total revenues. An analysis of operating expenses is shown below.

Insurance administrative expenses of $156 million were up6.6% in 2017 when compared with the prior year period of $146 million. As a percentage of total premium, insurance administrative expenses were 6.3% in 2017 compared with 6.2% in 2016. The increase in other employee costs was due primarily to higher pension expense driven by lower interest rates. The increase in information technology costs was due to investments that will enhance our customer

experience, improve our data analytics capabilities, improve our ability to react quickly to future changes and bolster our information security programs.

The increase in stock compensation expense was primarily due to higher expense associated with equity awards, reflecting Torchmark's higher share price as compared with the same period a year ago.

Investments (excess investment income), comparing the first nine months of 2017 with the first nine months of 2016. We manage our capital resources including investments, debt, and cash flow through the investment segment. Excess investment income represents the profit margin attributable to investment operations. It is the measure that we use to evaluate the performance of the investment segment as described in Note 10—Business Segments. It is defined as net investment income less the required interest on net policy liabilities and the interest cost associated with capital funding or “financing costs.”

We also view excess investment income per diluted common share as an important and useful measure to evaluate the performance of the investment segment. It is defined as excess investment income divided by the total diluted weighted average shares outstanding, representing the contribution by the investment segment to the consolidated earnings per share of the Company. Since implementing our share repurchase program in 1986, we have used $7.0 billion of cash flow to repurchase Torchmark shares (average split-adjusted price per diluted common share of $15.90) after determining that the repurchases provided a greater return than other investment alternatives. Share repurchases reduce excess investment income because of the foregone earnings on the cash that would otherwise have been invested in interest-bearing assets, but they also reduce the number of shares outstanding. In order to put all capital resource uses on a comparable basis, we believe that excess investment income per diluted share is an appropriate measure of the investment segment.

The following table summarizes Torchmark’s investment income, excess investment income, and excess investment income per diluted common share.

(1) Interest bearing policy liabilities, net of deferred acquisition costs and excluding the attributed unrealized gains and losses thereon.

Excess investment income for the 2017 period increased9%to$182 million when compared to $166 million in the same period in 2016. The increase in excess investment income is primarily attributed to flat interest expense and an increase in net investment income due to the decline in the negative impact of delays of receiving Medicare Part D reimbursements. On a per diluted common share basis, excess investment income increased13%, higher than the percentage increase in the dollar amount of excess investment income as a result of our share repurchase program.

Net investment incomeincreased$34 million or 6% in 2017, below the 7% increase in average invested assets (with fixed maturities at amortized cost) over the same period last year. Net investment income has been negatively impacted

37

during recent years by low interest rates on new investments and the turnover of higher-yielding assets in the portfolio. As such, growth in net investment income has been slower than the growth in mean invested assets in recent years. The effective annual yield earned on the fixed maturity portfolio was 5.68% in the first nine months of 2017, compared with 5.80% a year earlier. The decrease in the overall portfolio yield during recent periods is due primarily to investing at lower yield rates than the overall portfolio yield rates and reinvesting at yield rates lower than disposition yield rates. We currently expect that the average annual turnover of fixed maturity assets during the next five years will not exceed 1% to 2% of the portfolio and that this turnover will not have a material negative impact on investment income.

Should interest rates rise, especially long-term rates, Torchmark's net investment income would benefit due to higher interest rates on new purchases. While such a rise in interest rates could adversely affect the fair value of the fixed maturities portfolio, we could withstand an increase in interest rates of approximately 90 to 95 basis points before the net unrealized gains on our fixed maturity portfolio as of September 30, 2017 would be eliminated. Should interest rates increase further than that, we would not be concerned with potential interest rate driven unrealized losses in our fixed maturity portfolio because we have the intent and, more importantly, the ability, to hold our fixed maturities to maturity.

Required interest on net insurance policy liabilities reduces net investment income since it is the amount of net investment income considered by management necessary to “fund” net insurance policy liabilities, which is the net of the benefit reserve liability and deferred acquisition cost asset. As such, it is removed from the investment segment and applied to the insurance segments to offset the effect of the interest required by the insurance segments. As discussed in Note 10—Business Segments, management believes this provides a more meaningful analysis of the investment and insurance segments. Required interest is based on the actuarial interest assumptions used to discount the benefit reserve liability and to amortize the deferred acquisition costs for our insurance policies in force. The great majority of our life and health insurance policies are fixed interest-rate protection policies, not investment products, and are accounted for under current accounting guidance for long-duration insurance products which mandates that interest rate assumptions for a particular block of business be “locked in” for the life of that block. Each calendar year, we set the discount rate to be used to calculate the benefit reserve liability and deferred acquisition cost asset for all insurance policies issued that year. That rate is based on the new money yields that we expect to earn on cash flow received in the future from policies of that issue year, and cannot be changed. The discount rate used for policies issued in the current year has no impact on the in force policies issued in prior years as the rates of all prior issue years are also locked in. As such, the overall discount rate for the entire in force block is a weighted average of the discount rates being used from all issue years. Changes in the overall weighted-average discount rate over time are caused by changes in the mix of the reserves and the deferred acquisition cost asset by issue year on the entire block of in force business. Business issued in the current year has very little impact on the overall weighted-average discount rate due to the size of our in force business.

Required interest on net insurance policy liabilities increased$18 million or 5% to $390 million, in line with the growth in average net interest-bearing insurance policy liabilities.

Financing costs on our debt were flat in the first nine months of 2017 at $63 million.

Investments (acquisitions), comparing the first nine months of 2017 with the first nine months of 2016. Torchmark’s investment policy calls for investing primarily in investment grade fixed maturities that meet our quality and yield objectives. We generally prefer to invest in securities with longer maturities because they more closely match the long-term nature of our policy liabilities. We believe this strategy is appropriate because our cash flows from operations and invested assets are positive, stable and predictable. If longer-term securities that meet our quality and yield objectives are not available, we do not relax our quality objectives, but instead, consider investing in shorter or lower yielding securities, taking into consideration the slope of the yield curve and other factors.

The following table summarizes selected information for fixed maturity purchases. The effective annual yield shown is the yield calculated to the “worst call date.” For non-callable bonds, the worst-call date is always the maturity date. For callable bonds, the worst-call date is the call date that produces the lowest yield (or the maturity date, if the yield calculated to the maturity date is lower than the yield calculated to each call date).

Approximately 96% of our investments at book value are in a diversified fixed-maturity portfolio, the same percentage as at year end. Policy loans, which are secured by policy cash values, make up approximately 3% of our investments. We also have insignificant investments in equity securities and other long-term investments. Because fixed maturities represent such a significant portion of our investment portfolio, the remainder of the discussion of portfolio composition will focus on fixed maturities.

At September 30, 2017, fixed maturities had a fair value of $16.7 billion, compared with $15.2 billion at December 31, 2016. The net unrealized gain position in the fixed-maturity portfolio increased from $1.1 billion at December 31, 2016 to $1.7 billion at September 30, 2017. The September 30, 2017 net unrealized gain consisted of gross unrealized gains of $1.8 billion offset by $93 million of gross unrealized losses, compared with the December 31, 2016 net unrealized gain which consisted of a gross unrealized gain of $1.3 billion and a gross unrealized loss of $216 million.

Corporate securities, which consist of bonds and redeemable preferred stocks, were the largest component of the fixed maturity portfolio, representing 88% of amortized cost and 89% of fair value. The remainder of the portfolio is invested primarily in securities issued by the U.S. government and U.S. municipalities. The Company holds insignificant amounts in foreign government bonds, collateralized debt obligations, asset-backed securities, and agency mortgage-backed securities. Corporate securities are diversified over a variety of industry sectors and issuers; the total fixed maturity portfolio consisted of 600 issuers. The net unrealized gain of the fixed maturity portfolio increased $681 million from December 31, 2016.

An analysis of the fixed maturity portfolio at September 30, 2017 by a composite quality rating is shown in the table below. The composite quality rating for each security is the average of the security’s ratings as assigned by Moody’s Investor Service, Standard & Poor’s, Fitch Ratings, and Dominion Bond Rating Service, LTD. The ratings assigned by these four nationally recognized statistical rating organizations are evenly weighted when calculating the average. The composite quality rating is created using a methodology developed by Torchmark Corporation using ratings from the various rating agencies noted above (It should be noted that the composite quality rating is not a Standard & Poor's credit rating. Standard and Poor's does not sponsor, endorse or promote the composite quality rating and shall not be liable for any use of the composite quality rating.) Included in the chart below are private placement fixed maturity holdings of $593 million at amortized cost ($615 million at fair value). The ratings for these holdings were assigned by the third party managers of those securities.

Of the $14.9 billion of fixed maturities at amortized cost as of September 30, 2017, $14.3 billion or 96% were investment grade with an average rating of A-. Below-investment-grade bonds were $661 million with an average rating of B+. Below-investment-grade bonds at amortized cost were 16% of our shareholders’ equity, excluding the effect of unrealized gains and losses on fixed maturities as of September 30, 2017. Overall, the total portfolio was rated BBB+ based on amortized cost, the same as at the end of 2016.

As noted earlier, our investment policy calls for investing primarily in fixed maturities that are investment grade and meet our quality and yield objectives. Thus, any increases in below-investment-grade issues are typically a result of ratings downgrades of existing holdings. Our investment portfolio does not contain counterparty risks as we are not a party to any derivatives contracts. We also do not participate in securities lending and we have no off-balance sheet investments.

(2) Torchmark calculates the average life and duration of the fixed maturity portfolio two ways: (a) based on the next call date which is the next call date for callable bonds and the maturity date for noncallable bonds, and (b) based on the maturity date of all bonds, whether callable or not.

(3) Effective duration is a measure of the price sensitivity of a fixed-income security to a particular change in interest rates.

Realized Gains and Losses, comparing the first nine months of 2017 with the first nine months of 2016. As discussed in Note 10—Business Segments, our core business of providing insurance coverage requires us to maintain a large and diverse investment portfolio to support our insurance liabilities. From time to time, investments are disposed of or written down prior to maturity, resulting in realized gains or losses. Because these dispositions and write-downs are outside the course of our normal operations, management removes the effects of such gains and losses when evaluating its overall core operating results.

Financial Condition

Liquidity. Liquidity provides Torchmark with the ability to meet on demand the cash commitments required to support our business operations and meet our financial obligations. Our liquidity is evidenced by consistent positive cash flow, a portfolio of marketable investments, and our line of credit facility.

Insurance subsidiary liquidity. The operations of our insurance subsidiaries have historically generated substantial cash inflows in excess of immediate cash needs. Sources of cash flows for the insurance subsidiaries include primarily premium and investment income. Cash outflows from operations include policy benefit payments, commissions, administrative expenses and taxes. The funds to provide for policy benefits, the majority of which are paid in future periods, are invested primarily in long-term fixed maturities as they better match the long-term nature of these obligations. In addition to investment income, maturities and scheduled repayments in the investment portfolio are sources of cash. Excess cash available from the insurance subsidiaries’ operations is generally distributed as a dividend to the parent company, subject to regulatory restriction. The dividends are generally paid in amounts equal to the subsidiaries’ prior year statutory net income excluding realized capital gains. While the leading source of the excess cash is investment income, due to our high underwriting margins and effective expense control, a significant portion of the excess cash also comes from underwriting income.

Parent Company liquidity. An important source of Parent Company liquidity is the dividends from the insurance subsidiaries noted above. These dividends are received throughout the year and are used by the Parent Company to pay dividends on common and preferred stock, interest and principal repayment requirements on Parent Company debt, and operating expenses of the Parent Company. In the first nine months of 2017, the Parent Company received $309 million of cash dividends from subsidiaries, compared with $273 million in 2016. The increase in cash dividends received from subsidiaries was primarily due to the timing of dividend payments. For the full year 2017, cash dividends from subsidiaries are expected to total approximately $452 million.

Additional sources of liquidity for the Parent Company are cash, intercompany receivables, intercompany borrowings, and a credit facility. At September 30, 2017, the Parent Company had $55 million of invested cash and net intercompany receivables. The credit facility is discussed below.

Credit Facility. We have a credit facility with a group of lenders allowing for unsecured revolving borrowings and stand-by letters of credit up to $750 million, which could be extended up to $1 billion. We may request the extension, however, it is not guaranteed. Up to $250 million in letters of credit can be issued against the facility. The facility serves as a back-up credit line for a commercial paper program under which we may issue commercial paper at any time, with total commercial paper outstanding not to exceed the facility maximum, less any letters of credit issued. Interest on the commercial paper program is charged at variable rates. This facility was amended in May 2016 to extend the maturity date of the facility to May 2021. The amendment also allowed for an additional $100 million term loan to be issued under the facility rate structure. The term loan was issued during 2016 and will be repaid in quarterly escalating installments with a balloon payment of $75 million due in May 2021. Interest on the term loan is computed and paid

43

monthly at 125 basis points plus 1 month LIBOR. In accordance with the agreement, we are subject to certain covenants regarding capitalization. As of September 30, 2017, we were in full compliance with those covenants.

Commercial paper outstanding and any amortization payments of the term loan due within one year are included in short-term debt. The remaining balance of the term loan is included in long-term debt.

The following table presents certain information about our commercial paper borrowings.

Our balance of commercial paper outstanding at September 30, 2017 was $306 million compared with $263 million at the previous year end. We have had no difficulties in accessing the commercial paper market under this facility during the nine month periods ended September 30, 2017 and 2016.

In summary, Torchmark expects to have readily available funds for the foreseeable future to conduct its operations and to maintain target capital ratios in the insurance subsidiaries through internally generated cash flow and the credit facility. In the unlikely event that more liquidity is needed, the Parent Company could generate additional funds through multiple sources including, but not limited to, the issuance of debt, an additional short-term credit facility, and intercompany borrowing.

Consolidated liquidity. Consolidated net cash inflows from continuing operations were $1 billion in the first nine months of 2017, compared with $889 million in the same period of 2016. The increase is primarily attributable to timing of cash disbursements and fluctuations in amounts recorded in other liabilities. In addition to cash inflows from operations, our companies received proceeds from maturities, calls, and repayments of fixed maturities available for sale in the amount of $306 million during the 2017 period. As previously noted under the caption Credit Facility, we have in place a line of credit facility. The insurance companies have no additional outstanding credit facilities.

Cash and short-term investments were $154 million at September 30, 2017, compared with $148 million at December 31, 2016. In addition to these liquid assets, the entire $16.7 billion (fair value at September 30, 2017) portfolio of fixed income securities is available for sale in the event of an unexpected need. Approximately 96% of our fixed income securities are publicly traded, freely tradable under SEC Rule 144, or qualified for resale under SEC Rule 144A. We generally expect to hold fixed income securities to maturity, and even though these securities are classified as available for sale, we have the ability and intent to hold any securities which are temporarily impaired until they mature. Our strong cash flows from operations, on-going investment maturities, and credit line availability make any need to sell securities for liquidity highly unlikely.

Capital Resources. Management targets an aggregate capital ratio for its insurance subsidiaries of approximately 325% of Company action level regulatory capital under Risk-Based Capital (RBC), a formula designed by insurance regulatory authorities to monitor the adequacy of capital. The 325% target is considered sufficient for the subsidiaries because of their strong reliable cash flows, the relatively low risk of their product mix, and because that ratio is in line with rating agency expectations for Torchmark. At December 31, 2016, our insurance subsidiaries had an aggregate

44

RBC ratio of approximately 324%. Should we experience impairments and/or ratings downgrades within our fixed maturity portfolio in the future, the ratio could fall below targeted levels. In such a case, management believes more than sufficient liquidity exists at the Parent Company to make additional contributions as necessary to maintain the targeted ratio.

On a consolidated basis, Torchmark’s capital structure consists of short-term debt (comprised of the commercial paper outstanding discussed above, current maturities of the term loan, and current maturities of funded debt), long-term debt (comprised of long-term maturities of funded debt and long term maturities of the term loan), and shareholders’ equity.

The outstanding long-term debt at book value was $1.1 billion at September 30, 2017 and December 31, 2016. An analysis of debt issues outstanding is as follows at September 30, 2017.

On April 5, 2016, Torchmark completed the issuance and sale of $300 million aggregate principal amount of Torchmark’s 6.125% Junior Subordinated Debentures due 2056. The Debentures were sold pursuant to Torchmark’s shelf registration statement on Form S-3, filed September 25, 2015. The net proceeds from the sale of the Debentures were $290 million, after giving effect to the underwriting discount and estimated expenses of the offering of the Debentures. Torchmark used the net proceeds from the offering of the Debentures primarily to repay the $250 million outstanding principal amount plus accrued interest of $8 million on its 6.375% Senior Notes that were due June 15, 2016.

As previously noted under the caption Results of Operationsin this report, we acquired 3.2 million of our outstanding common shares under our share repurchase program during the first nine months of 2017. These shares were acquired at a cost of $243 million (average of $76.46 per share), compared with purchases of 4.2 million shares at a cost of $240 million (average of $57.58 per share) in the first nine months of 2016.

On August 28, 2017, the Company announced that it had declared a quarterly dividend of 0.15 per share. This dividend was paid on November 1, 2017.

Shareholders’ equity was $5.2 billion at September 30, 2017. This compares with $4.6 billion at December 31, 2016 and $5.1 billion at September 30, 2016. During the nine months since December 31, 2016, shareholders’ equity was

45

increased by $442 million of after-tax unrealized gains in the fixed-maturity portfolio as interest rates have decreased over the period. In addition, shareholders' equity was increased by net income of $427 million. Share purchases of $243 million noted above during the period reduced shareholders’ equity.

We are required by GAAP to revalue our available for sale fixed maturity portfolio to fair market value at the end of each accounting period. These changes, net of their associated impact on deferred acquisition costs and income tax, are reflected directly in shareholders’ equity.

While GAAP requires our fixed maturity assets to be revalued, it does not permit interest-bearing insurance policy liabilities supported by those assets to be valued at fair value in a consistent manner, with changes in value applied directly to shareholders’ equity. However, due to the size of both the investment portfolio and our policy liabilities, this inconsistency in measurement can have a material impact on shareholders’ equity. Because of the long-term nature of our fixed maturities and liabilities and the strong cash flows generated by our insurance subsidiaries, we have the intent and ability to hold our securities to maturity. As such, we do not expect to incur realized gains or losses due to fluctuations in the market value of fixed maturities caused by interest rate changes or losses caused by temporarily illiquid markets. Accordingly, management removes the effect of this rule when analyzing Torchmark’s balance sheet, capital structure, and financial ratios in order to provide a more consistent and meaningful portrayal of the Company’s financial position from period to period.

The following table presents selected data related to capital resources. Additionally, the table presents the effect of the GAAP requirement to revalue our fixed maturity assets on relevant items so that investors and other financial statement users may determine its impact on our capital structure.

Cautionary Statements

We caution readers regarding certain forward-looking statements contained in the previous discussion and elsewhere in this document, and in any other statements made by, or on behalf of Torchmark whether or not in future filings with the Securities and Exchange Commission. Any statement that is not a historical fact or that might otherwise be considered an opinion or projection concerning Torchmark or its business, whether express or implied, is meant as and should be considered a forward-looking statement. Such statements represent management’s opinions concerning future operations, strategies, financial results or other developments. We specifically disclaim any obligation to update or revise any forward-looking statement because of new information, future developments, or otherwise.

Such events or developments could include, but are not necessarily limited to:

1) Economic and other conditions leading to unexpected changes in lapse rates and/or sales of our policies, as well as levels of mortality, morbidity, and utilization of health care services that differ from Torchmark’s assumptions;

2) Regulatory developments, including changes in governmental regulations (particularly those impacting taxes and changes to the Federal Medicare program that would affect Medicare Supplement);

3) Market trends in the senior-aged health care industry that provide alternatives to traditional Medicare (such as Health Maintenance Organizations and other managed care or private plans) and that could affect the sales of traditional Medicare Supplement insurance;

4) Interest rate changes that affect product sales and/or investment portfolio yield;

5) General economic, industry sector or individual debt issuers’ financial conditions that may affect the current market value of securities we own, or that may impair an issuer’s ability to make principal and/or interest payments due on those securities;

6) Changes in pricing competition;

7) Litigation results;

8) Levels of administrative and operational efficiencies that differ from our assumptions;

9) The ability to obtain timely and appropriate premium rate increases for health insurance policies from our regulators;

10) The customer response to new products and marketing initiatives;

11) Reported amounts in the financial statements which are based on management’s estimates and judgments which may differ from the actual amounts ultimately realized; and

12) Compromise by a malicious actor or other event that causes a loss of secure data from, or inaccessibility to, our computer and other information technology systems.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no quantitative or qualitative changes with respect to market risk exposure during the nine months ended September 30, 2017.

Item 4. Controls and Procedures

Torchmark, under the direction of the Co-Chairmen and Chief Executive Officers and the Executive Vice President and Chief Financial Officer, has established disclosure controls and procedures that are designed to ensure that information required to be disclosed by Torchmark in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to Torchmark’s management, including the Co-Chairmen and Chief Executive Officers and the Executive Vice President and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

As of the end of the fiscal quarter completed September 30, 2017, an evaluation was performed under the supervision and with the participation of Torchmark management, including the Co-Chairmen and Chief Executive Officers and the Executive Vice President and Chief Financial Officer, of Torchmark’s disclosure controls and procedures (as those terms are defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon their evaluation, the Co-Chairmen and Chief Executive Officers and the Executive Vice President and Chief Financial Officer have concluded that Torchmark’s disclosure controls and procedures are effective as of the date of this Form 10-Q. In compliance with Section 302 of the Sarbanes-Oxley Act of 2002 (18 U.S.C. §1350), each of these officers executed a Certification included as an exhibit to this Form 10-Q.

For the quarter ended September 30, 2017, there have not been any changes in Torchmark’s internal control over financial reporting or in other factors that could significantly affect this control over financial reporting subsequent to the date of their evaluation which have materially affected, or are reasonably likely to materially affect, Torchmark’s internal control over financial reporting. No material weaknesses in such internal controls were identified in the evaluation and as a consequence, no corrective action was required to be taken.

Part II – Other Information

Item 1. Legal Proceedings

Torchmark and its subsidiaries, in common with the insurance industry in general, are subject to litigation, including claims involving tax matters, alleged breaches of contract, torts, including bad faith and fraud claims based on alleged wrongful or fraudulent acts of agents of Torchmark’s subsidiaries, employment discrimination, and miscellaneous other causes of action. Based upon information presently available, and in light of legal and other factual defenses available to Torchmark and its subsidiaries, management does not believe that such litigation will have a material adverse effect on Torchmark’s financial condition, future operating results or liquidity; however, assessing the eventual outcome of litigation necessarily involves forward-looking speculation as to judgments to be made by judges, juries and appellate courts in the future. This bespeaks caution, particularly in states with reputations for high punitive damage verdicts. Torchmark’s management recognizes that large punitive damage awards bearing little or no relation to actual damages continue to be awarded by juries in jurisdictions in which Torchmark and its subsidiaries have substantial business, creating the potential for unpredictable material adverse judgments in any given punitive damage suit.

See further discussion of litigation and unclaimed property audits in Note 6—Commitments and Contingencies.

At its August 7, 2017meeting, the Board of Directors reaffirmed the Company’s share repurchase program in amounts and with timing that management, in consultation with the Board, determines to be in the best interest of the Company. The program has no defined expiration date or maximum shares to be repurchased.

Accounting Changes and Error Corrections [Abstract]

New Accounting Standards

New Accounting Standards

Accounting Pronouncements Not Yet Adopted

ASU 2016-01: In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which primarily revises the classification and measurement of certain equity investments such that they will be measured at fair value through net income. Additionally, it eliminates the cost method for partnerships and joint ventures and requires these types of investments to be accounted for under the fair value through net income method or equity method. Lastly, the guidance will require certain disclosures associated with fair value of financial instruments. This standard will become effective for the Company beginning January 1, 2018. The adoption will not have a significant impact on the financial statements as we have limited ownership in equity investments and partnerships, representing less than 1% of total invested assets.

ASU 2016-02: In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires all lessees to report a right-of-use asset and a lease liability for leases with a term life greater than 12 months. Operating and financing leases will be recognized on the balance sheet going forward. Additional qualitative and quantitative disclosures will be required. This standard will become effective for the Company beginning January 1, 2019 and will require recognizing and measuring leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The Company does not expect the adoption to have a significant impact on the financial statements. Refer to the 2016 Form 10-K Note 15—Commitments and Contingencies for consideration of the noncancellable operating lease commitments. The Company does not have any lessor commitments.

ASU 2016-13: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments as well as to change the loss impairment methodology for available-for-sale debt securities. This standard will become effective on January 1, 2020. The applicable section of the standard related to debt securities requires a prospective transition. The Company does not expect the adoption to have a significant impact on the financial statements as we have limited credit losses with respect to our available-for-sale portfolio.

ASU 2016-15: In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments to provide uniformity in the classification of cash receipts and payments recorded in the statement of cash flows including debt prepayment or debt extinguishment costs, settlement of zero-coupon bonds, and proceeds from the settlement of insurance claims. This standard will become effective on January 1, 2018 and will not have a significant impact on the financial statements.

ASU 2016-16: In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other Than Inventory. This guidance was issued to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory by allowing the immediate recognition of the current and deferred income tax effects. Current guidance prohibits the recognition of current and deferred income taxes for an intra-entity transfer until the asset has been sold to an outside party. This new guidance should be applied on a modified retrospective approach and will become effective on January 1, 2018. This adoption will not have a significant impact on the financial statements.

ASU 2017-04:In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This guidance was issued to simplify the subsequent measurement of goodwill through the elimination of Step 2 from the goodwill impairment test which required a hypothetical purchase price allocation. It will become effective on January 1, 2020 and should be applied on a prospective basis. This adoption will not have a significant impact on the financial statements.

ASU 2017-07: In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance was issued to simplify the reporting of pension costs by disaggregating the service-cost component from the other components of net benefit costs and reporting it separately on the income statement. The service-cost component is the only component of net benefit cost that will be eligible for capitalization. The guidance will become effective on January 1, 2018 with a retrospective transition method for separation of net benefit costs and a prospective transition method for the capitalization of service costs. The Company does not expect the adoption to have a significant impact on the financial statements as the change in pension capitalization should be less than 1% of Total Benefits and Expenses on the Consolidated Statement of Operations for the year.

ASU 2017-08: In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance was issued to shorten the amortization period for certain callable debt securities held at a premium. The guidance requires the premium to be amortized to the earliest call date. It will become effective on January 1, 2019 with early adoption permitted, including during interim periods. The adoption is to be applied on a modified retrospective basis through an adjustment to retained earnings. This adoption will not have a significant impact on the financial statements.

ASU 2017-09: In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. This guidance was issued to provide clarity and guidance regarding changes to the terms or conditions of a share-based payment award that requires an entity to apply modification accounting. It will become effective on January 1, 2018 with early adoption permitted, including adoption in any interim periods. The Company does not expect the adoption to have a significant impact on the financial statements as modifications to stock compensation are infrequent.

Other-Than-Temporary Impairments:

In accordance with the other-than-temporary impairment (OTTI) policy, the Company evaluated its fixed maturities available for sale in an unrealized loss position to determine if there was any impairment for the quarter. Gross unrealized losses may fluctuate quarter over quarter due to adverse factors in the market that affect our holdings, such as changes in the interest rates or credit spreads. While the Company holds securities that may be in an unrealized loss position from time to time, Torchmark has the ability and intent to hold these investments to recovery. Additionally, Torchmark does not expect to be required to sell any of its securities due to the strong cash flows generated by its insurance operations.

For the nine months ended September 30, 2017, the Company recorded $245 thousand ($159 thousand, net of tax) in OTTI. For the comparable period in 2016, the Company concluded that there were no other-than-temporary impairments.

Unrealized Loss Analysis:

The following table discloses information about fixed maturities available for sale in an unrealized loss position.

	Less than Twelve Months	Twelve Months or Longer	Total
Number of issues (CUSIP numbers) held:
As of September 30, 2017	151	109	260
As of December 31, 2016	407	94	501

Torchmark’s entire fixed maturity portfolio consisted of 1,514 issues at September 30, 2017 and 1,565 issues at December 31, 2016. The weighted average quality rating of all unrealized loss positions as of September 30, 2017 was BBB compared with BBB+ as of December 31, 2016.

The following table discloses unrealized investment losses by class and major sector of fixed maturities available for sale at September 30, 2017 for the period of time in a loss position. Torchmark considers these investments to be only temporarily impaired.

Discontinued Operations

Discontinued Operations

At December 31, 2015, Torchmark met the criteria to account for its Medicare Part D Prescription Drug Plan business as a discontinued operation. Historically, the business was a reportable segment. Effective July 1, 2016, Torchmark sold its Medicare Part D Prescription Drug Plan business to an unaffiliated third party.

The sale resulted in a net gain of $1.8 million ($1.2 million net of tax) in 2016. The operating results from discontinued operations are reflected in income for the nine months ended September 30, 2017. The remaining assets and liabilities reflected on the Torchmark balance sheet related to discontinued operations are receivables and payables associated with the 2016 and prior plan years that are expected to be settled in the ordinary course of business during 2017 and 2018.

The net assets related to discontinued operations at September 30, 2017 and December 31, 2016 were as follows:

	September 30, 2017		December 31, 2016
Assets:
Due premiums	$	3,945	$	8,840
Other receivables(1)	64,627		118,692
Total assets related to discontinued operations	68,572		127,532
Liabilities:

Total liabilities related to discontinued operations	49,328		27,424
Net assets	$	19,244	$	100,108

(1) At September 30, 2017, other receivables included $65 million from the Centers for Medicare and Medicaid Services (CMS). At December 31, 2016, other receivables included $50 million from the Centers for Medicare and Medicaid Services (CMS) and $69 million from drug manufacturer rebates.

(2) At September 30, 2017, the balance included $35.8 million due to CMS. At December 31, 2016, the balance included a $3.6 million contingent purchase price reserve.

Income from discontinued operations for the three and nine months ended September 30, 2017 and 2016 was as follows:

Commitments and Contingencies

Litigation:

Torchmark and its subsidiaries, in common with the insurance industry in general, are subject to litigation, involving various matters where we are either the defendant or the plaintiff. Torchmark subsidiaries are also currently the subject of audits regarding the identification, reporting and escheatment of unclaimed property arising from life insurance policies and a limited number of annuity contracts. In each of these matters, based upon information presently available, management does not believe that such litigation or audits will have a material adverse effect on Torchmark’s financial condition, future operating results or liquidity.

As previously reported, litigation was filed on February 10, 2015 against Torchmark subsidiary, Globe Life And Accident Insurance Company (Globe) in Oklahoma County, Oklahoma District Court (Proctor v. Globe Life And Accident Insurance Company, Case No. CJ-2015-838) asserting claims for breach of the implied covenants of good faith and fair dealing and for false representation, deceit and conversion in connection with Globe’s denial of plaintiff’s claim on a life insurance policy for non-payment of premium. Plaintiff, who had alleged that Globe had improperly retained 12 monthly premium payments on a policy that was treated as lapsed or not returned to in-force status, seeks actual and punitive damages, prejudgment interest, attorney fees, costs and other relief. Plaintiff subsequently amended his complaint to add allegations of conversion and civil theft on behalf of a purported class of Globe’s U.S. policyholders who had paid premiums retained by Globe when their policies were lapsed and not reinstated at the time of the premium payments. Globe removed the case to the U.S. District Court for the Western District of Oklahoma (Case No. 15-CV-0070-M) on July 10, 2015 and filed a Motion to Dismiss on July 17, 2015. The Court denied plaintiff’s Motion to Remand back to state court on October 26, 2015, but allowed the plaintiff to amend the complaint to assert a putative class action in federal court. Plaintiff filed a Motion for Class Certification on September 23, 2016. Globe filed a Response in Opposition on November 4, 2016. The Court denied plaintiff’s Motion for Class Certification on August 18, 2017.

With respect to current litigation, at this time management believes that the possibility of a material judgment adverse to Torchmark is remote, and no estimate of range can be made for loss contingencies that are at least reasonably possible but not accrued.

Guaranty Fund Assessment:

In 2017, the Commonwealth Court of Pennsylvania issued orders placing Penn Treaty Network America Insurance Company (Penn Treaty) and affiliate American Network Insurance Company (ANIC) in liquidation due to financial difficulties. In such instances, the various state guaranty fund associations employ funding mechanisms, through assessments to their member companies, to cover the obligations of the insolvent entities. Consequently, the Company continues to receive guaranty fund assessments from the state associations related to these companies. The Company has projected its share of the ultimate assessments from these insolvencies based on assumptions about future events and its market share of premiums by state. The total estimated assessment for Torchmark's subsidiaries is approximately$10 millionof which$1.4 million is estimated to be unrecoverable. We are anticipating the remaining amount of the assessments to be recovered through premium tax credits.

During the nine months ended September 30, 2017, the Company made $19 million in cash contributions to the qualified pension plans. Torchmark will not make any additional cash contributions in 2017.

With respect to the Company’s active nonqualified noncontributory SERP, life insurance policies on the lives of plan participants have been established with an unaffiliated carrier to provide for a portion of the Company’s obligations under the plan. These policies along with investments deposited with an unaffiliated trustee were previously placed in a Rabbi Trust to provide for the payment of the plan obligations. At September 30, 2017, the combined value of the insurance policies and investments in the Rabbi Trust to support plan liabilities were $94 million, compared with $86 million at December 31, 2016. Since this plan is nonqualified and therefore is treated as unfunded, the values of the insurance policies and investments are recorded as Other assets in the Condensed Consolidated Balance Sheets and are not included in the chart of plan assets above.

Segment Reporting [Abstract]

Business Segments

Business Segments

Torchmark's reportable segments are based on the insurance product lines it markets and administers: life insurance, health insurance, and annuities. These major product lines are set out as reportable segments because of the common characteristics of products within these categories, comparability of margins, and the similarity in regulatory environment and management techniques. Torchmark's chief operating decision makers evaluate the overall performance of the operations of the Company in accordance with these segments.

Management’s measure of profitability for each insurance segment is insurance underwriting margin, which is underwriting income before other income and insurance administrative expenses. It represents the profit margin on insurance products before administrative expenses, and is calculated by deducting net policy obligations (claims incurred and change in reserves), commissions and other acquisition expenses from premium revenue. Torchmark further views the profitability of each insurance product segment by the marketing groups that distribute the products of that segment: direct response, independent agencies, or captive agencies.

Torchmark’s management prefers to evaluate the performance of its underwriting and investment activities separately, rather than allocating investment income to the underwriting results. As such, the investment function is presented as a stand-alone segment. The investment segment includes the management of the investment portfolio, debt, and cash flow. Management’s measure of profitability for this segment is excess investment income, which is the income earned on the investment portfolio less the required interest on net policy liabilities and financing costs. Financing costs include the interest on Torchmark’s debt. Other income and insurance administrative expense are classified in a separate Other segment.

The majority of the Company’s required interest on net policy liabilities (benefit reserves less the deferred acquisition cost asset) is not credited to policyholder accounts. Instead, it is an actuarial assumption for discounting cash flows in the computation of benefit reserves and the amortization of the deferred acquisition cost asset. Investment income required to fund the required interest on net policy liabilities is removed from the investment segment and applied to the insurance segments to eliminate the effect of the required interest from the insurance segments. As a result, the investment segment measures net investment income against the required interest on net policy liabilities and financing costs, while the insurance segments simply measure premiums against net policy benefits and expenses. Management believes this presentation facilitates a more meaningful analysis of the Company’s underwriting and investment performance as the underwriting results are based on premiums, claims, and expenses and are not affected by unanticipated fluctuations in investment yields.

As noted, Torchmark’s “core operations” are insurance and investment management. The insurance segments issue policies for which premiums are collected for the eventual payment of policy benefits. In addition to policy benefits, operating expenses are incurred including acquisition costs, administrative expenses, and taxes. Because life and health contracts can be long term, premium receipts in excess of current expenses are invested. Investment activities, conducted by the investment segment, focus on seeking quality investments with a yield and term appropriate to support the insurance product obligations. These investments generally consist of fixed maturities, and, over the long term, the expected yields are taken into account when setting insurance premium rates and product profitability expectations. As a result, fixed maturities are generally held for long periods to support the liabilities, and Torchmark generally expects to hold investments until maturity. However, dispositions of investments occur from time to time, generally for reasons such as credit concerns, calls by issuers, or other factors.

Since Torchmark does not actively trade investments, realized gains and losses from the disposition and write down of investments are generally incidental to operations and are not considered a material factor in insurance pricing or product profitability. While from time to time these realized gains and losses could be significant to net income in the period in which they occur, they generally have a limited effect on the yield of the total investment portfolio. Further, because the proceeds of the disposals are reinvested in the portfolio, the disposals have little effect on the size of the portfolio and the income from the reinvestments is included in net investment income. Therefore, management removes realized investment gains and losses from results of core operations when evaluating the performance of the Company. For this reason, these gains and losses are excluded from Torchmark’s operating segments.

Torchmark accounts for its stock options and restricted stock under current accounting guidance requiring stock options and stock grants to be expensed based on fair value at the time of grant. Management considers stock compensation expense to be an expense of the Parent Company. Therefore, stock compensation expense is treated as a corporate expense in Torchmark’s segment analysis.

As discussed in Note 6—Commitments and Contingencies, the Company received an assessment from various state guaranty fund associations for the liquidation of Penn Treaty and its affiliate. The total estimated assessment for Torchmark's subsidiaries is approximately$10 millionof which$1.4 million is estimated to be unrecoverable. We are anticipating the remaining amount of the assessments to be recovered through premium tax credits. The assessment expenses were considered a non-operational event and therefore were excluded from the core underwriting operations of the Company.

The following tables set forth a reconciliation of Torchmark’s revenues and operations by segment to its pretax income and each significant line item in its Condensed Consolidated Statements of Operations.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation: The accompanying condensed consolidated financial statements of Torchmark Corporation (Torchmark or alternatively, the Company) have been prepared in accordance with the instructions to Form 10-Q. Therefore, they do not include all of the annual disclosures required by accounting principles generally accepted in the United States of America (GAAP). However, in the opinion of management, these statements include all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial position at September 30, 2017, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended September 30, 2017 and 2016. The interim period condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements that are included in the Form 10-K filed with the Securities Exchange Commission (SEC) on February 27, 2017.

Accounting Pronouncements Not Yet Adopted

Accounting Pronouncements Not Yet Adopted

ASU 2016-01: In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which primarily revises the classification and measurement of certain equity investments such that they will be measured at fair value through net income. Additionally, it eliminates the cost method for partnerships and joint ventures and requires these types of investments to be accounted for under the fair value through net income method or equity method. Lastly, the guidance will require certain disclosures associated with fair value of financial instruments. This standard will become effective for the Company beginning January 1, 2018. The adoption will not have a significant impact on the financial statements as we have limited ownership in equity investments and partnerships, representing less than 1% of total invested assets.

ASU 2016-02: In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires all lessees to report a right-of-use asset and a lease liability for leases with a term life greater than 12 months. Operating and financing leases will be recognized on the balance sheet going forward. Additional qualitative and quantitative disclosures will be required. This standard will become effective for the Company beginning January 1, 2019 and will require recognizing and measuring leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The Company does not expect the adoption to have a significant impact on the financial statements. Refer to the 2016 Form 10-K Note 15—Commitments and Contingencies for consideration of the noncancellable operating lease commitments. The Company does not have any lessor commitments.

ASU 2016-13: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments as well as to change the loss impairment methodology for available-for-sale debt securities. This standard will become effective on January 1, 2020. The applicable section of the standard related to debt securities requires a prospective transition. The Company does not expect the adoption to have a significant impact on the financial statements as we have limited credit losses with respect to our available-for-sale portfolio.

ASU 2016-15: In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments to provide uniformity in the classification of cash receipts and payments recorded in the statement of cash flows including debt prepayment or debt extinguishment costs, settlement of zero-coupon bonds, and proceeds from the settlement of insurance claims. This standard will become effective on January 1, 2018 and will not have a significant impact on the financial statements.

ASU 2016-16: In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other Than Inventory. This guidance was issued to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory by allowing the immediate recognition of the current and deferred income tax effects. Current guidance prohibits the recognition of current and deferred income taxes for an intra-entity transfer until the asset has been sold to an outside party. This new guidance should be applied on a modified retrospective approach and will become effective on January 1, 2018. This adoption will not have a significant impact on the financial statements.

ASU 2017-04:In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This guidance was issued to simplify the subsequent measurement of goodwill through the elimination of Step 2 from the goodwill impairment test which required a hypothetical purchase price allocation. It will become effective on January 1, 2020 and should be applied on a prospective basis. This adoption will not have a significant impact on the financial statements.

ASU 2017-07: In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This guidance was issued to simplify the reporting of pension costs by disaggregating the service-cost component from the other components of net benefit costs and reporting it separately on the income statement. The service-cost component is the only component of net benefit cost that will be eligible for capitalization. The guidance will become effective on January 1, 2018 with a retrospective transition method for separation of net benefit costs and a prospective transition method for the capitalization of service costs. The Company does not expect the adoption to have a significant impact on the financial statements as the change in pension capitalization should be less than 1% of Total Benefits and Expenses on the Consolidated Statement of Operations for the year.

ASU 2017-08: In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Topic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance was issued to shorten the amortization period for certain callable debt securities held at a premium. The guidance requires the premium to be amortized to the earliest call date. It will become effective on January 1, 2019 with early adoption permitted, including during interim periods. The adoption is to be applied on a modified retrospective basis through an adjustment to retained earnings. This adoption will not have a significant impact on the financial statements.

ASU 2017-09: In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. This guidance was issued to provide clarity and guidance regarding changes to the terms or conditions of a share-based payment award that requires an entity to apply modification accounting. It will become effective on January 1, 2018 with early adoption permitted, including adoption in any interim periods. The Company does not expect the adoption to have a significant impact on the financial statements as modifications to stock compensation are infrequent.
