(UNAUDITED)

(Dollar amounts in thousands except per share data)

Note 1—Significant Accounting Policies

Basis of Presentation: The accompanying condensed consolidated financial statements 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 March 31, 2016, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended March 31, 2016 and 2015. 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 26, 2016.

Note 2—New Accounting Standards

Accounting Pronouncements Adopted

ASU 2014-15: In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40) (ASU 2014-15). This accounting standard requires management to perform interim and annual assessments of the entity's ability to continue its business operations within one year of the date of issuance of its financial statements. The Company must then provide certain disclosure if there is substantial doubt about its ability to continue as a going concern. As of January 1, 2016, the Company adopted this standard with no impact to the financial statements.

ASU 2016-09: In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) to simplify certain aspects of accounting for share-based payment award transactions including: (a) income tax consequences; (b) classification in the statement of cash flows; and (c) accounting for forfeitures.Torchmark elected to early adopt this standard as of January 1, 2016, as permitted. This new accounting standard primarily affects Torchmark's computations of net income and diluted shares outstanding and thus earnings per share.

While the intent of the adoption of this guidance is simplification, inherent changes in future share prices and volume of stock option exercises are expected to result in increased volatility in net income and earnings per share in future periods. As provided by the new standard, the adoption is prospective and thus will impact only 2016 and future periods.

Below is a listing of the effects of the adoption of this guidance:

• Condensed consolidated statement of operations: The Company recorded $2 million in additional excess tax benefits as a component of income taxes, which resulted in an increase in net income as compared with the quarter ended March 31, 2015 when the excess tax benefits of $5 million were recorded as a component of additional paid-in capital on the balance sheet.

• Weighted average diluted shares:The weighted average diluted shares outstanding were adjusted to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. This change resulted in diluted weighted average shares outstanding calculated of 123.3 million for the quarter ended March 31, 2016, as compared with 122.7 million as would have been calculated under the previous guidance.

• Earnings per share: The adoption resulted in a $0.01 increase in earnings per share for the three months ended March 31, 2016.

• Condensed consolidated statement of cash flows: The excess tax benefits related to share-based payments of $2 million were presented as a component of operating activities in the same manner as other cash flows related to income taxes. In prior years, the excess tax benefits were reclassified from operating activities to financing activities. The prior period amounts were not adjusted.

Note 2—New Accounting Standards (continued)

Accounting Pronouncements Not Yet Adopted

ASU 2016-02: In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), (ASU 2016-02) which requires all lessees to report a right-of-use asset and a lease liability for most leases. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. The 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 is currently evaluating the standard to determine its impact.

Other-Than-Temporary Impairments:

Based on the Company's evaluation of its fixed maturities in an unrealized loss position in accordance with the OTTI policy, the Company concluded that there were no other-than-temporary impairments during the three-month periods ended March 31, 2016 and 2015, respectively.

As of quarter end 2016, previously written down securities remaining in the portfolio were carried at a fair value of $57 million, or less than 1% of the fair value of the fixed maturity portfolio. Torchmark is continuously monitoring the market conditions impacting its portfolio, including holdings negatively impacted by recent low prices for oil and other commodities. While adverse market conditions for an extended duration could lead to some ratings downgrades among these holdings, Torchmark has the ability and intent to hold these investments to recovery, and does not expect to be required to sell any of its securities.

Note 5—Discontinued Operations

At December 31, 2015, Torchmark met the criteria to account for its Medicare Part D business as a discontinued operation and expects the business to be sold during 2016. Historically, the business was a reportable segment. However, Torchmark no longer emphasizes its Medicare Part D business due to declining margins, increased risks, higher drug costs, and increased administrative and compliance costs. Management believes this sale will allow the Company to better focus on its core protection life and health insurance businesses as well as provide additional capital to invest.

The net assets held for sale at March 31, 2016 and December 31, 2015 were as follows:

	March 31, 2016			December 31, 2015
Assets:
Due premiums	$	5,084		$	8,041
Other receivables(1)	265,818			287,765

The effective income tax rate for the three months ended March 31, 2016 differed from the effective income tax rate for the same period ended March 31, 2015 primarily as a result of the Company adopting ASU 2016-09 as of January 1, 2016. As a result of the adoption, the excess tax benefits related to share-based awards are now recorded through income tax expense rather than additional paid-in capital. See Note 2—New Accounting Standards for further discussion.

Note 7—Debt Transactions

On April 5, 2016, Torchmark completed the issuance and sale of $300 million in aggregate principal 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 intends to use the net proceeds from the offering of the debentures to repay the $250 million outstanding principal, plus accrued interest, on the 6.375% Senior Notes due June 15, 2016, and for general corporate purposes.

The liability for the funded defined-benefit pension plans was $408 million at March 31, 2016 and $406 million at December 31, 2015. No cash contributions were made to the qualified pension plans during the three months ended March 31, 2016. Torchmark expects to make cash contributions to these plans during 2016 in an amount not to exceed $20 million. With respect to the Company’s non-qualified supplemental retirement plan, life insurance policies on the lives of plan participants have been established with an unaffiliated carrier to fund a portion of the Company’s obligations under the plan. These policies, as well as investments deposited with an unaffiliated trustee, were previously placed in a Rabbi Trust to provide for payment of the plan obligations. At March 31, 2016, the combined value of the insurance policies and investments in the Rabbi Trust to support plan liabilities were $81 million, compared with $79 million at

year-end 2015. Since this plan is non-qualified, 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. The liability for the non-qualified pension plan was $68 million at March 31, 2016 and $67 million at December 31, 2015.

Note 9—Earnings Per Share

A reconciliation of basic and diluted weighted-average shares outstanding is as follows:

	For the Three Months Ended   March 31,
	2016	2015
Basic weighted average shares outstanding	121,480,805	127,121,101
Weighted average dilutive options outstanding	1,831,938	1,465,751
Diluted weighted average shares outstanding	123,312,743	128,586,852
Antidilutive shares	1,489,562	605,188

As discussed earlier in Note 2—New Accounting Standards, the Company adopted ASU 2016-09 on January 1, 2016. The adoption resulted in an adjustment to the weighted average diluted shares outstanding to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. This change has been applied prospectively and resulted in diluted weighted average shares outstanding of 123.3 million for the quarter ended March 31, 2016, as compared with 122.7 million as would have been calculated under the previous guidance.

Note 10—Business Segments

Torchmark is comprised of life insurance companies which primarily market individual life and supplemental health insurance products through niche distribution channels to middle income Americans. Torchmark’s core operations are insurance marketing and underwriting, and management of its investments. The insurance marketing and underwriting operation is segmented by the types of insurance products offered: life, health, and annuity. Annuity revenue is classified as “Other premium.” 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 benefits and expenses. We believe this

Note 10—Business Segments (continued)

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. Dispositions of investments occur from time to time, generally as a result of credit concerns, calls by issuers, or other factors usually beyond the control of management.

Dispositions are sometimes required in order to maintain the Company’s investment policies and objectives. Investments are also occasionally written down as a result of other-than-temporary impairment. Torchmark does not actively trade investments. As a result, 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.

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 Segments. The measures of profitability described in Note 10—Business Segments 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. 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—Business Segments 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 periods ended March 31, 2016 and 2015. Additionally, a table in that note, Analysis of Profitability by Segment, provides a summary of the 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.

A discussion of operations by each segment follows later in this report. These discussions compare the first three months of 2016 with the same period of 2015, unless otherwise noted. The following discussions are presented in the manner we view our operations, as described in Note 10—Business Segments.

Highlights, comparing the first three months of 2016 with the first three months of 2015. Net income per diluted share increased6% to $1.01 from $0.95. Included in net income in 2016 were after-tax realized investment gains of $190 thousand compared with gains of $77 thousand in 2015. Realized investment gains and losses are presented more fully under the caption Realized Gains and Losses in this report.

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, 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. 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. 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.

Total premium income rose5% in 2016 to $780 million. Total net sales were flat at $136 million when compared with the same period in 2015. First-year collected premium was $113 million for the 2016 period, compared with $110 million for the 2015 period. The increase in first-year collected premium is primarily the result of prior year life insurance sales growth in the American Income Exclusive Agency.

Life insurance premium income grew6% to $544 million. Life net sales were flat at $104 million when compared with the same period in 2015. First-year collected life premium grew7% during the first three months of 2016 to $79 million over the same period in 2015 of $74 million. Life underwriting margin as a percent of premium was down to 27% as a result of higher than expected Globe Life Direct Response policy obligations and additional costs of supporting certain distribution channels. Underwriting income increased to $144 million for the first three months of 2016 compared with $141 million for the same period in 2015.

Health insurance premium income increased3% to $236 million over the prior year total of $229 million. Health net sales fell1% to $32 million for the three month period, primarily as a result of a 3% decrease in Medicare Supplement sales. First-year collected health premium fell7% to $34 million. Health margins declined to 22%, with underwriting income of $52 million for the first three months of 2016, due to increased acquisition costs.

22

Insurance administrative expenses were up 5.5% in 2016 when compared with the prior year period. The increase in administrative expenses is primarily due to investments in information technology that will standardize and streamline operations and enhance the customer experience.

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 share increased 2% in 2016 to $0.44 from $0.43, while the dollar amount of excess investment income was flat at $55 million. The increase in per share excess investment income in relation to the flat dollar amount resulted from share purchases over the period, as discussed later in this report. Net investment income rose$5 million or 3% to $197 million, slightly below the 4% growth in our average investment portfolio at amortized cost. The average effective yield on the fixed-maturity portfolio, which represented 95% of our investments at amortized cost, decreased to 5.83% in the 2016 period from 5.87% in the prior period. Required interest rose5% or $5 million to $123 million, in line with growth in average net policy liabilities. Financing costs were $19 million in both periods. Please refer to the discussion under Capital Resources for more information on debt and interest expense.

In the first three months of 2016, we invested new money in our fixed-maturity portfolio at an effective annual yield on new investments of 5.03%, compared with 4.47% in the same period of 2015, with an average rating of BBB+, and an average life of twenty six years. Approximately 94% of the portfolio at amortized cost was investment grade at March 31, 2016. Cash and short-term investments were $157 million at that date, compared with $116 million at December 31, 2015.

The net unrealized gain position in our fixed-maturity portfolio grew from $506 million at December 31, 2015 to $970 million during the first three months of 2016, primarily due to a decrease in Treasury rates during 2016. The fixed-maturity portfolio contains no commercial mortgage-backed securities. We have no direct investments in residential mortgages, nor are we a party to any derivative contracts, including credit default swaps. We do not participate in securities lending, we have no off-balance sheet investments, and we have only insignificant exposures to European Sovereign debt consisting of $2 million of German government bonds. Our exposure to Puerto Rican obligations atMarch 31, 2016was less than $600 thousand.

We have an on-going share repurchase program which began in 1986 which is reviewed quarterly and is reaffirmed by the Board of Directors on an annual basis. The program was reaffirmed on August 5, 2015. 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 with excess cash flow. 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 three month periods ended March 31, 2016 and 2015.

A detailed discussion of our operations by component segment follows.

Life insurance, comparing the first three months of 2016 with the first three months of 2015. Life insurance is our predominant segment, representing 70% of premium income and 73% of insurance underwriting margin in the first three months of 2016. In addition, investments supporting the reserves for life business generate the majority of excess investment income attributable to the investment segment. Life insurance premium income increased 6% to $544 million. The following table presents Torchmark’s life insurance premium by distribution channel.

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 other affinity groups and referrals to help ensure sustainable growth. The life business of this agency is Torchmark’s highest-margin life business and it is the largest contributor to life premium of any distribution channel at 41% of Torchmark’s total. This group produced premium income of $220 million, an increase of 9%. First-year collected premium was $42 million, an increase of 13%. Net sales rose7% to $50 million. Sales growth in our captive agencies is generally dependent on growth in the size of the agency force. The American Income Agency's average agent count decreased 2% to 6,206 for the three months ended March 31, 2016 compared with 6,317 for the same period in 2015. The average agent count is based on the actual count at the end of each week during the period. Sales increased despite the decline in agent count due to increased agent productivity. The American Income Agency has been focusing on growing and strengthening middle management to support sustainable growth of the agency force. To accomplish this, we have placed an increased emphasis on agent training programs and financial incentives that appropriately reward agents at all levels for helping develop and train personnel. The agency continues to provide more home-office and webinar training programs. These programs are designed to provide each agent, from new recruits to top level managers, coaching and instruction specifically designed for each individual’s level of experience and responsibility.

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 has been fueled by constant innovation. In recent years, electronic media production has grown rapidly as management has aggressively increased marketing activities related to internet and mobile technology, and has focused on driving traffic to the 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 rose7% to $200 million, representing 37% of Torchmark’s total life premium in the first three months of 2016. Net sales of $41 million for this group decreased8%. The sales decline was expected as we reduced insert media circulation to eliminate less profitable segments. First-year collected premium was $27 million for both periods.

The Liberty National Exclusive Agency markets individual and group life insurance to middle-income customers. Life premium income for this agency was $68 million in the 2016 and 2015 periods. First-year collected premium increased8% to $7 million.

Net sales for the Liberty National Agency increased11% to $9 million. This is the largest percentage increase of any of Torchmark's distributions channels.The Liberty average agent count increased 5% to 1,542 for the three months ended March 31, 2016 compared with 1,464 for the same period in 2015. 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 predominately life insurance. The Other Agencies contributed $56 million of life premium income, or 10% of Torchmark’s total in the first three months of 2016, but contributed only 3% of net sales for the period.

Life Insurance Summary of Results (Dollar amounts in thousands)
	Three Months Ended March 31,						Increase
	2016			2015			(Decrease)
	Amount		% of Premium	Amount		% of Premium	Amount		%
Premium and policy charges	$	544,151	100	$	513,342	100	$	30,809	6

Insurance underwriting income before other income and administrative expense	$	144,300	27	$	141,403	28	$	2,897	2

Life insurance underwriting income before insurance administrative expense was $144 million in the first three months of 2016 compared with $141 million for the same period in 2015. As a percentage of premium, underwriting margins declined to 27% from 28%. The decrease in underwriting margin as a percentage of premium was due to higher Globe Life Direct Response policy obligations. The higher claims in the Globe Life Direct Response Unit primarily relate to policies issued since 2011 where additional prescription information was used in the underwriting process for certain business in order to improve the overall mortality. To date, improvements in actual mortality have been less than expected, causing higher than expected net policy obligations.

Health insurance, comparing the first three months of 2016 with the first three months of 2015. 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 2016 period, while the health underwriting margin accounted for 26% of total underwriting margin, reflective of the lower underwriting margin as a percent 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.

Health premium increased3% to $236 million in the 2016 period. Medicare Supplement premium increased4% to $119 million, while other limited-benefit health premium increased2% to $117 million.

Health net sales decreased1% to $32 million. Medicare Supplement net sales decreased3% to $13 million in 2016. Group sales can vary significantly from period to period. Limited-benefit net sales were flat at $18 million. Health first-year collected premium fell7% to $34 million, due to a high level of group sales in the third and fourth quarter 2014.

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 $88 million, representing 37% of Torchmark’s total health premium. Net sales were $12 million, or 38% of Torchmark’s health sales. This agency is Torchmark’s largest producer of Medicare Supplement insurance, with Medicare Supplement premium income of $85 million. The UA Independent Agency represents approximately 71% of all Torchmark Medicare Supplement premium and 88% of Medicare Supplement net sales. Medicare Supplement premium in this agency rose 7%. Total health premium also increased 6%. Net sales of the Medicare Supplement product decreased 2% in 2016; individual sales were up 2%, but group sales declined 10%. As noted earlier, Group Medicare Supplement sales have historically fluctuated from period to period.

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 through geographic expansion and continuing incorporation of Torchmark’s recruiting programs. The Family Heritage Agency contributed $11 million in net sales in the three months of 2016, compared with $12 million for the same period in 2015, a decrease of 9%. Health premium income was $57 million for the three month period of 2016, representing 24% of Torchmark’s health premium. This compared with $54 million or 23% of

29

health premium in the prior year period. The average agent count was 827 for the three months ended March 31, 2016, compared with 784 for the same period in 2015, an increase of 5%.

The Liberty National Exclusive Agency represented 22% of all Torchmark health premium income at $52 million in the three months of 2016. 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 2016, health premium income in the Liberty Agency declined $2 million to $52 million from prior year premium total of $54 million. Liberty’s health premium decline has been due primarily to its declining Medicare Supplement block.

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 2016 period. The American Income Exclusive Agency primarily markets accident plans. The Direct Response group markets primarily Medicare Supplements to employer or union-sponsored groups. Direct Response added $2 million of Medicare Supplement net sales in 2016.

Operating expenses, comparing the first three months of 2016 with the first three months of 2015. Operating expenses consist of insurance administrative expenses and parent company expenses. Also included is stock compensation expense, which is viewed by us as a 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 were up 5.5% in 2016 when compared with the prior year period. As a percentage of total premium, insurance administrative expenses were 6.2% in 2016, unchanged from the same period last year. Total operating expenses increased 3.7%. The increase in administrative expenses is primarily due to investments in information technology that will standardize and streamline operations and enhance the customer experience. The decline in stock compensation expense was primarily due to lower expense associated with restricted stock awards.

Investments (excess investment income), comparing the first three months of 2016 with the first three months of 2015. 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 in the Notes to the Condensed Consolidated Financial Statements. 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 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 $6.5 billion of cash flow to repurchase Torchmark shares (average split-adjusted price per share of $15.06) 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.

Excess investment income for the 2016 period was flat at $55 million when compared with the same period in 2015. On a per share basis, excess investment income increased 2% as a result of our share repurchases over the past 12 months. Excess investment income has been negatively impacted during recent years by low interest rates and the turnover of higher yielding assets in the portfolio as well as certain aspects of Medicare Part D as discussed below.

Net investment income rose $5 million or 3% in 2016, slightly below the 4% increase in average invested assets (with fixed maturities at amortized cost) over the same period last year. The effective annual yield on the fixed maturity portfolio was 5.83% in the first three months of 2016, compared with 5.87% a year earlier. The reduction in the average portfolio yield rate was primarily a result of lower new money yield rates and reinvesting proceeds from bonds that were called in 2016 at yield rates less than the rates we earned on the bonds before they were called. We currently expect that the average 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.

Net investment income has also been negatively affected in 2016 by the CMS requirement for us to cover Medicare Part D claim costs in the current period that are ultimately the responsibility of the government, but are not reimbursed until the following year. We incurred extensive upfront costs in 2015 that will not be reimbursed by CMS until November 2016, and will continue to front additional significant costs in 2016 that will not be reimbursed until 2017. We also experience delays from the time certain claims are paid until related drug rebates are received from various pharmaceutical companies. These delays cause a lag in the timing of investable cash flows that result in lower investment income than would have been earned absent the delays. Due to these delays, our net investment income was reduced by approximately $3 million in the first three months of 2016, and we expect net investment income to be reduced by approximately $6 million for the remainder of 2016.

Should long-term interest rates rise, especially long-term rates, Torchmark would benefit due to higher net investment income on new purchases. We could withstand an increase in interest rates of approximately 55 to 65 basis points before the net unrealized gains on our fixed maturity portfolio as of March 31, 2016 would be eliminated (assuming there were no credit related valuation declines). 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 liabilitiesreduces net investment income as it is the amount of net investment income considered by management necessary to “fund” the required interest included in the insurance segments. As such, it is removed from the investment segment and applied to the insurance segments to offset the

32

effect of the required interest from 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 in discounting the benefit reserve liability and the amortization of 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 of business. Each calendar year, we set the discount rate to be used to calculate the benefit reserve liability and the amortization of the 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 $5 million or 5% to $123 million, in line with the growth in average net interest-bearing insurance policy liabilities.

Financing costs on our debt increased 2% to $19 million. More information concerning debt can be found in the Capital Resources section of this report.

Investments (acquisitions), comparing the first three months of 2016 with the first three months of 2015. Torchmark’s investment policy calls for investing in fixed maturities that are investment grade and 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 95% of our investments at book value are in a diversified fixed-maturity portfolio. Policy loans, which are secured by policy cash values, make up approximately 4% 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 March 31, 2016, fixed maturities had a fair value of $14.5 billion, compared with $13.8 billion at December 31, 2015. The net unrealized gain position in the fixed-maturity portfolio increased from $506 million at December 31, 2015 to $970 million at March 31, 2016, primarily as a result of a decrease in Treasury rates. The March 31, 2016 net unrealized gain consisted of gross unrealized gains of $1.4 billion offset by $394 million of gross unrealized losses, compared with the December 31, 2015 net unrealized gain which consisted of a gross unrealized gain of $1.1 billion and a gross unrealized loss of $564 million.

Corporate securities, which consist of bonds and redeemable preferred stocks, were the largest component of the fixed maturity portfolio, representing 87% of amortized cost and 87% of fair value. The remainder of the portfolio is invested primarily in securities issued by the U.S. government, U.S. municipalities, and foreign governments. The Company holds insignificant amounts in collateralized debt obligations, asset-backed securities, and agency mortgage-backed securities. Corporate securities are diversified over a variety of industry sectors and issuers. At March 31, 2016, the financial, utility, and energy sectors represented approximately 23%, 15%, and 12%, respectively, of fixed maturities at amortized cost and 24%, 16%, and 10%, respectively, of fixed maturities at fair value. Otherwise, no single sector represented more than 10% of the corporate fixed maturity portfolio at either amortized cost or fair value. The total fixed maturity portfolio consists of 569 issuers, with 203 issuers within the financial, utility, and energy sectors.

The net unrealized gain of the fixed maturity portfolio increased $464 million from December 31, 2015. The financial, utility, energy and basic materials sectors experienced increases of $28 million, $78 million, $37 million, and $67 million, respectively, in net unrealized gains fromDecember 31, 2015 to March 31, 2016. The fair values of the financial, utility, energy, and basic materials sectors increased approximately 3%, 4%, 3%, and 12%, respectively, while the fair value of the entire portfolio increased 5% for the period. The current low price of oil and other commodities has a negative impact on the operations of the companies whose bonds we hold in the energy and basic materials sectors. While a sustained period of low prices might lead to some downgrades in ratings, we don't expect to incur any losses from defaults in the foreseeable future.

An analysis of the fixed-maturity portfolio at March 31, 2016 by a composite quality rating is shown in the table below. The composite 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.

Of the $13.5 billion of fixed maturities at amortized cost as of March 31, 2016, $12.7 billion or 94% were investment grade with an average rating of A-. Below-investment-grade bonds were $771 million with an average rating of B+. Below-investment-grade bonds at amortized cost were 20% of our shareholders’ equity, excluding the effect of

36

unrealized gains and losses on fixed maturities as of March 31, 2016. Overall, the total portfolio was rated A- based on amortized cost, the same as at the end of 2015.

An analysis of the changes in our portfolio of below-investment-grade bonds at amortized cost during the first three months of 2016 is as follows:

Our investment policy is to acquire only investment-grade obligations. Thus, any increases in below-investment-grade issues are a result of ratings downgrades of existing holdings. Our investment portfolio contains no commercial mortgage-backed securities. We have no direct investments in residential mortgages, nor do we have any counterparty risks as we are not a party to any derivative contracts, including credit default swaps. We do not participate in securities lending, we have no off-balance sheet investments, and we have only insignificant exposures to European Sovereign debt consisting of $2 million of German government bonds. Our exposure to Puerto Rican obligations atMarch 31, 2016was less than $600 thousand.

(1) Tax-equivalent basis. The yield on tax-exempt securities is adjusted to produce a yield equivalent to the pretax yield on taxable securities.

(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 three months of 2016 with the first three months of 2015. 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 writedowns are outside the course of our normal operations, management removes the effects of such gains and losses when evaluating its overall core operating results.

The following table summarizes our tax-effected realized gains (losses) by component.

Financial Condition

Liquidity. Liquidity provides Torchmark with the ability to meet on demand the cash commitments required by our business operations and financial obligations. Our liquidity is evidenced by positive cash flow, a portfolio of marketable investments, and the availability of a 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 to meet these long-term 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.

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 three months of 2016, the Parent Company received $96 million of cash dividends from subsidiaries, compared with $77 million in 2015. For the full year 2016, cash dividends from subsidiaries are expected to total approximately $420 million.

Additional sources of liquidity for the Parent Company are cash, intercompany receivables, and a credit facility. At March 31, 2016, the Parent Company had $66 million of invested cash and net intercompany receivables. The credit facility is discussed below.

Short-term borrowings. We have a credit facility with a group of lenders allowing for unsecured borrowings and stand-by letters of credit up to $750 million, which could be extended up to $1 billion. Up to $250 million in letters of credit can be issued against the facility. The facility is further designated as a back-up credit line for a commercial paper program under which we may either borrow from the credit line or issue commercial paper at any time, with total commercial paper outstanding not to exceed the facility maximum, less any letters of credit issued. Interest is charged at variable rates. The facility terminates in July 2019 and has no ratings-based acceleration triggers which would require early repayment. In accordance with the agreement, we are subject to certain covenants regarding capitalization. As of March 31, 2016, we were in full compliance with these covenants.

38

Included in short-term debt is the commercial paper outstanding, noted above, as well as the current maturity of long-term debt. At March 31, 2016, we had $250 million par value of our 6.375% Senior Notes due in June 15, 2016 classified as short-term debt.

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

Daily-weighted average interest rate (annualized)	0.73		%	0.41		%
Maximum daily amount outstanding during period (par value)	$	412,676		$	356,500

Our balance of commercial paper outstanding at March 31, 2016 was $308 million compared with $241 million at the previous year end. We have had no difficulties in accessing the commercial paper market under this facility during the three-month periods ended March 31, 2016 and 2015.

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 operations were $338 million in the first three months of 2016, compared with $280 million in the same period of 2015. In addition to cash inflows from operations, our companies received proceeds from maturities, calls, and repayments of fixed maturities in the amount of $45 million during the 2016 period. As previously noted under the caption Short-term borrowings, we have in place a line of credit facility. The insurance companies have no additional outstanding credit facilities.

Cash and short term investments were $157 million at March 31, 2016, compared with $116 million at December 31, 2015. In addition to these liquid assets, the entire $14.5 billion (fair value at March 31, 2016) portfolio of fixed-income and equity securities is available for sale in the event of an unexpected need. Approximately 96% of our fixed-income and equity 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, investment maturities, and credit line availability make any need to sell securities for liquidity highly unlikely.

Capital Resources. Our insurance subsidiaries maintain capital at a level adequate to support their current operations and meet the requirements of the regulatory authorities and the rating agencies. Our insurance subsidiaries generally target a capital ratio of around 325% of Company Action Level required regulatory capital under Risk-Based Capital (RBC), a measure established by insurance regulatory authorities to monitor the adequacy of capital. The 325% target is considered sufficient because of our insurance companies’ strong reliable cash flows, the relatively low risk of their product mix, and because that ratio exceeds regulatory requirements and has been in line with rating agency expectations for Torchmark. As of December 31, 2015, our insurance subsidiaries had a consolidated RBC ratio of 317%. Although this was slightly below our targeted level of 325%, it was primarily due to lower Part D earnings and

39

fourth quarter downgrades greater than estimated. While we do not currently anticipate any significant changes to our targeted consolidated RBC level, should we believe that the RBC ratios of the insurance companies are being reduced due to downgrades in their investment portfolios that are temporary and that may reverse in the near future, we may choose to temporarily target a lower RBC ratio. We have available assets on hand and credit availability at the Parent Company to make additional contributions as necessary to maintain the targeted ratio. As discussed further in the next section below, the Parent Company will have approximately $40 million in additional proceeds from the $300 million debt offering in April at its disposal, if necessary, for additional capital or other financing needs of the insurance subsidiaries.

On a consolidated basis, Torchmark’s capital structure consists of short-term debt (comprised of the commercial paper outstanding discussed above and current maturities of funded debt), long-term funded debt, and shareholders’ equity. The outstanding long-term debt at book value was $744 million at March 31, 2016 and December 31, 2015. An analysis of long-term debt issues outstanding is as follows at March 31, 2016.

(1) An additional $150 million par value and book value is held by insurance subsidiaries that eliminates in consolidation.

(2) Interest paid at 3 month LIBOR plus 330 basis points, resets each quarter.

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 intends to use the net proceeds from the offering of the debentures to repay the $250 million outstanding principal amount plus accrued interest on the 6.375% Senior Notes due June 15, 2016 and for general corporate purposes, including capital or other financing at our insurance subsidiaries if necessary. The Senior Notes are included in short-term debt.

As previously noted under the caption Results of Operationsin this report, we acquired 1.5 million of our outstanding common shares under our share repurchase program during the first three months of 2016. These shares were acquired at a cost of $80 million (average of $53.26 per share), compared with purchases of 1.7 million shares at a cost of $90 million in the first three months of 2015.

On March 1, 2016, the Company announced that it had declared a quarterly dividend of $0.14 per share which was paid on April 29, 2016.

Shareholders’ equity was $4.4 billion at March 31, 2016. This compares with $4.1 billion at December 31, 2015 and $4.9 billion at March 31, 2015. During the three months since December 31, 2015, shareholders’ equity was increased by $300 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 $124 million. Share purchases of $80 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

40

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 this GAAP requirement on relevant line 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.

Forward-looking statements are based upon estimates and assumptions that are subject to significant business, economic and competitive uncertainties, many of which are beyond our control. If these estimates or assumptions prove to be incorrect, the actual results of Torchmark may differ materially from the forward-looking statements made on the basis of such estimates or assumptions. Whether or not actual results differ materially from forward-looking statements may depend on numerous foreseeable and unforeseeable events or developments, which may be national in scope, related to the insurance industry generally, or applicable to Torchmark specifically. Such events or developments could include, but are not necessarily limited to:

1) Changing general economic 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 and Medicare Part D insurance);

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) Our inability to obtain timely and appropriate premium rate increases for health insurance policies due to regulatory delay;

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

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.

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 three months ended March 31, 2016.

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 March 31, 2016, 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.

As of the date of this Form 10-Q for the quarter ended March 31, 2016, 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.

43

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.

Torchmark subsidiaries are 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. These audits are being conducted by private entities that have contracted with forty-seven various states through their respective Departments of Revenue, and have not resulted in any financial assessment from any state nor indicated any liability. The audits are wide-ranging and seek large amounts of data regarding claims handling, procedures, and payments of contract benefits arising from unreported death claims. No estimate of range can be made at this time for loss contingencies related to possible administrative penalties or amounts that could be payable to the states for the escheatment of abandoned property.

Item 1A. Risk Factors

Torchmark has had no material changes to its risk factors.

At its August 5, 2015 meeting, 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 Adopted

ASU 2014-15: In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40) (ASU 2014-15). This accounting standard requires management to perform interim and annual assessments of the entity's ability to continue its business operations within one year of the date of issuance of its financial statements. The Company must then provide certain disclosure if there is substantial doubt about its ability to continue as a going concern. As of January 1, 2016, the Company adopted this standard with no impact to the financial statements.

ASU 2016-09: In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) to simplify certain aspects of accounting for share-based payment award transactions including: (a) income tax consequences; (b) classification in the statement of cash flows; and (c) accounting for forfeitures.Torchmark elected to early adopt this standard as of January 1, 2016, as permitted. This new accounting standard primarily affects Torchmark's computations of net income and diluted shares outstanding and thus earnings per share.

While the intent of the adoption of this guidance is simplification, inherent changes in future share prices and volume of stock option exercises are expected to result in increased volatility in net income and earnings per share in future periods. As provided by the new standard, the adoption is prospective and thus will impact only 2016 and future periods.

Below is a listing of the effects of the adoption of this guidance:

• Condensed consolidated statement of operations: The Company recorded $2 million in additional excess tax benefits as a component of income taxes, which resulted in an increase in net income as compared with the quarter ended March 31, 2015 when the excess tax benefits of $5 million were recorded as a component of additional paid-in capital on the balance sheet.

• Weighted average diluted shares:The weighted average diluted shares outstanding were adjusted to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. This change resulted in diluted weighted average shares outstanding calculated of 123.3 million for the quarter ended March 31, 2016, as compared with 122.7 million as would have been calculated under the previous guidance.

• Earnings per share: The adoption resulted in a $0.01 increase in earnings per share for the three months ended March 31, 2016.

• Condensed consolidated statement of cash flows: The excess tax benefits related to share-based payments of $2 million were presented as a component of operating activities in the same manner as other cash flows related to income taxes. In prior years, the excess tax benefits were reclassified from operating activities to financing activities. The prior period amounts were not adjusted.

Accounting Pronouncements Not Yet Adopted

ASU 2016-02: In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), (ASU 2016-02) which requires all lessees to report a right-of-use asset and a lease liability for most leases. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. The 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 is currently evaluating the standard to determine its impact.

Other-Than-Temporary Impairments:

Based on the Company's evaluation of its fixed maturities in an unrealized loss position in accordance with the OTTI policy, the Company concluded that there were no other-than-temporary impairments during the three-month periods ended March 31, 2016 and 2015, respectively.

As of quarter end 2016, previously written down securities remaining in the portfolio were carried at a fair value of $57 million, or less than 1% of the fair value of the fixed maturity portfolio. Torchmark is continuously monitoring the market conditions impacting its portfolio, including holdings negatively impacted by recent low prices for oil and other commodities. While adverse market conditions for an extended duration could lead to some ratings downgrades among these holdings, Torchmark has the ability and intent to hold these investments to recovery, and does not expect to be required to sell any of its securities.

Discontinued Operations

At December 31, 2015, Torchmark met the criteria to account for its Medicare Part D business as a discontinued operation and expects the business to be sold during 2016. Historically, the business was a reportable segment. However, Torchmark no longer emphasizes its Medicare Part D business due to declining margins, increased risks, higher drug costs, and increased administrative and compliance costs. Management believes this sale will allow the Company to better focus on its core protection life and health insurance businesses as well as provide additional capital to invest.

The net assets held for sale at March 31, 2016 and December 31, 2015 were as follows:

	March 31, 2016			December 31, 2015
Assets:

The effective income tax rate for the three months ended March 31, 2016 differed from the effective income tax rate for the same period ended March 31, 2015 primarily as a result of the Company adopting ASU 2016-09 as of January 1, 2016. As a result of the adoption, the excess tax benefits related to share-based awards are now recorded through income tax expense rather than additional paid-in capital. See Note 2—New Accounting Standards for further discussion.

On April 5, 2016, Torchmark completed the issuance and sale of $300 million in aggregate principal 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 intends to use the net proceeds from the offering of the debentures to repay the $250 million outstanding principal, plus accrued interest, on the 6.375% Senior Notes due June 15, 2016, and for general corporate purposes.

The liability for the funded defined-benefit pension plans was $408 million at March 31, 2016 and $406 million at December 31, 2015. No cash contributions were made to the qualified pension plans during the three months ended March 31, 2016. Torchmark expects to make cash contributions to these plans during 2016 in an amount not to exceed $20 million. With respect to the Company’s non-qualified supplemental retirement plan, life insurance policies on the lives of plan participants have been established with an unaffiliated carrier to fund a portion of the Company’s obligations under the plan. These policies, as well as investments deposited with an unaffiliated trustee, were previously placed in a Rabbi Trust to provide for payment of the plan obligations. At March 31, 2016, the combined value of the insurance policies and investments in the Rabbi Trust to support plan liabilities were $81 million, compared with $79 million at year-end 2015. Since this plan is non-qualified, 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. The liability for the non-qualified pension plan was $68 million at March 31, 2016 and $67 million at December 31, 2015.

A reconciliation of basic and diluted weighted-average shares outstanding is as follows:

Basic weighted average shares outstanding	121,480,805	127,121,101

As discussed earlier in Note 2—New Accounting Standards, the Company adopted ASU 2016-09 on January 1, 2016. The adoption resulted in an adjustment to the weighted average diluted shares outstanding to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. This change has been applied prospectively and resulted in diluted weighted average shares outstanding of 123.3 million for the quarter ended March 31, 2016, as compared with 122.7 million as would have been calculated under the previous guidance.

Segment Reporting [Abstract]

Business Segments

Business Segments

Torchmark is comprised of life insurance companies which primarily market individual life and supplemental health insurance products through niche distribution channels to middle income Americans. Torchmark’s core operations are insurance marketing and underwriting, and management of its investments. The insurance marketing and underwriting operation is segmented by the types of insurance products offered: life, health, and annuity. Annuity revenue is classified as “Other premium.” 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 benefits and expenses. We believe 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. Dispositions of investments occur from time to time, generally as a result of credit concerns, calls by issuers, or other factors usually beyond the control of management.

Dispositions are sometimes required in order to maintain the Company’s investment policies and objectives. Investments are also occasionally written down as a result of other-than-temporary impairment. Torchmark does not actively trade investments. As a result, 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.

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

The accompanying condensed consolidated financial statements 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 March 31, 2016, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended March 31, 2016 and 2015. 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 26, 2016.

Accounting Pronouncements Adopted and Not Yet Adopted

Accounting Pronouncements Adopted

ASU 2014-15: In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40) (ASU 2014-15). This accounting standard requires management to perform interim and annual assessments of the entity's ability to continue its business operations within one year of the date of issuance of its financial statements. The Company must then provide certain disclosure if there is substantial doubt about its ability to continue as a going concern. As of January 1, 2016, the Company adopted this standard with no impact to the financial statements.

ASU 2016-09: In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) to simplify certain aspects of accounting for share-based payment award transactions including: (a) income tax consequences; (b) classification in the statement of cash flows; and (c) accounting for forfeitures.Torchmark elected to early adopt this standard as of January 1, 2016, as permitted. This new accounting standard primarily affects Torchmark's computations of net income and diluted shares outstanding and thus earnings per share.

While the intent of the adoption of this guidance is simplification, inherent changes in future share prices and volume of stock option exercises are expected to result in increased volatility in net income and earnings per share in future periods. As provided by the new standard, the adoption is prospective and thus will impact only 2016 and future periods.

Below is a listing of the effects of the adoption of this guidance:

• Condensed consolidated statement of operations: The Company recorded $2 million in additional excess tax benefits as a component of income taxes, which resulted in an increase in net income as compared with the quarter ended March 31, 2015 when the excess tax benefits of $5 million were recorded as a component of additional paid-in capital on the balance sheet.

• Weighted average diluted shares:The weighted average diluted shares outstanding were adjusted to exclude excess tax benefits from the assumed proceeds in the diluted shares calculation. This change resulted in diluted weighted average shares outstanding calculated of 123.3 million for the quarter ended March 31, 2016, as compared with 122.7 million as would have been calculated under the previous guidance.

• Earnings per share: The adoption resulted in a $0.01 increase in earnings per share for the three months ended March 31, 2016.

• Condensed consolidated statement of cash flows: The excess tax benefits related to share-based payments of $2 million were presented as a component of operating activities in the same manner as other cash flows related to income taxes. In prior years, the excess tax benefits were reclassified from operating activities to financing activities. The prior period amounts were not adjusted.

Accounting Pronouncements Not Yet Adopted

ASU 2016-02: In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), (ASU 2016-02) which requires all lessees to report a right-of-use asset and a lease liability for most leases. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. The 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 is currently evaluating the standard to determine its impact.
