DOCUMENTS INCORPORATED BY REFERENCE

PART I

Item 1. Business

Torchmark Corporation (Torchmark) is an insurance holding company incorporated in Delaware in 1979. Its primary subsidiaries are American Income Life Insurance Company (American Income), Liberty National Life Insurance Company (Liberty National), Globe Life And Accident Insurance Company (Globe), United American Insurance Company (United American), and Family Heritage Life Insurance Company of America (Family Heritage).

Torchmark’s website is: www.torchmarkcorp.com. Torchmark makes available free of charge through its website, its annual report on Form 10-K, its quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports as soon as reasonably practicable after they have been electronically filed with or furnished to the Securities and Exchange Commission. Other information included in Torchmark's website is not incorporated into this filing.

The following table presents Torchmark’s business by primary marketing distribution method.

Insurance

Life Insurance

Torchmark’s insurance subsidiaries write a variety of nonparticipating ordinary life insurance products. These include traditional and interest sensitive whole-life insurance, term life insurance, and other life insurance. The following table presents selected information about Torchmark’s life products.

The distribution methods for life insurance products include direct response, exclusive agents and independent agents. These methods are described in more depth in the Distribution Method chart earlier in this report. The following table presents life annualized premium in force by distribution method.

Health Insurance

Torchmark offers Medicare Supplement and limited-benefit supplemental health insurance products that include primarily critical illness and accident plans. These policies are designed to supplement health coverage that applicants already own. Medicare Supplements are also offered to enrollees in the traditional fee-for-service Medicare program. Medicare Supplement plans are standardized by federal regulation and are designed to pay deductibles and co-payments not paid by Medicare.

The following table presents supplemental health annualized premium in force information for the three years ended December 31, 20162017 by product category.

The following table presents supplemental health annualized premium in force for the three years ended December 31, 20162017 by distribution method.

Annuities

Annuity products include single-premium and flexible-premium deferred annuities. Annuities in each of the three years ended December 31, 20162017 comprised less than 1% of premium.

Premium rates for life and health insurance products are established using assumptions as to future mortality, morbidity, persistency, investment income, expenses, and expenses.target profit margins. These assumptions are based on Company experience and projected investment earnings. Revenues for individual life and health insurance products are primarily derived from premium income, and, to a lesser extent, through policy charges to the policyholder account values on annuity products and certain individual life products. Profitability is affected to the extent actual experience deviates from the assumptions made in pricing and to the extent investment income varies from that which is required for policy reserves.

Collections for annuity products and certain life products are not recognized as revenues, but are added to policyholder account values. Revenues from these products are derived from charges to the account balances for insurance risk and administrative costs. Profits are earned to the extent these revenues exceed actual costs. Profits are also earned from investment income on the deposits invested in excess of the amounts credited to policyholder accounts.

The underwriting standards of each Torchmark insurance subsidiary are established by management. Each subsidiary uses information from the application and, in some cases, telephone interviews with applicants, inspection reports, pharmacy data, doctors’ statements and/or medical examinations to determine whether a policy should be issued in accordance with the application, with a different rating, with a rider, with reduced coverage or rejected.

Torchmark competes with other insurance carriers through policyholder service, price, product design, and sales efforts. While there are insurance companies competing with Torchmark, no individual company dominates any of Torchmark’s life or health markets.

Torchmark’s health insurance products compete with, in addition to the products of other health insurance carriers, health maintenance organizations, preferred provider organizations, and other health care-related institutions which provide medical benefits based on contractual agreements.

Management believes Torchmark companies operate at lower policy acquisition and administrative expense levels than peer companies. This allows Torchmark to have competitive rates while maintaining higher underwriting margins.

constitute a holding company system. Torchmark and its subsidiaries have registered as a holding company system pursuant to such legislation in Indiana, Nebraska, Ohio, and New York.

Insurance holding company system statutes and regulations impose various limitations on investments in subsidiaries, and may require prior regulatory approval for material transactions between insurers and affiliates and for the payment of certain dividends and other distributions.

At the end of 2016,2017, Torchmark had 3,1283,102 employees.

Item 1A. Risk Factors

Risks Related to Our Business

The insurance industry is a regulated industry, populated by many public and private companies. We operate in the life and health insurance sectors of the insurance industry, each withof which has its own set of risks.

Rating agencies also publish credit ratings for us. Credit ratings are indicators of a debt issuer’s ability to meet the terms of debt obligations in a timely manner. These ratings are important to our overall ability to access certain types of liquidity.capital. Actual or anticipated downgrades in our credit ratings, or an announcement that our ratings are under further review for a downgrade, could potentially have a negative effect on our financial condition and results of operations by limiting our access to capital markets, increasing the cost of debt, or impairing our ability to raise capital to refinance maturing debt obligations, thereby potentially limiting our capacity to support growth at our insurance subsidiaries or making it more difficult to maintain or improve the current financial strength ratings of our insurance subsidiaries.

Ratings reflect only the rating agency’s views and are not recommendations to buy, sell or hold our securities. Rating agencies assign ratings based upon several factors. While most of the factors relate to the rated company, some of the factors relate to the views of the rating agency, general economic conditions and circumstances outside the rated company’s control. In addition, rating agencies use various models and formulas to assess the strength of a rated

could impact the rating agencies’ judgment of the rating to be assigned to the rated company. There can be no assurance that our current credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if in each rating agency’s judgment, circumstances so warrant.agencies. We cannot predict what actions the rating agencies may take, or what actions we may take in response to the actions of the rating agencies which could negatively affect our business, financial condition and results of operations.

Employee errors in the handling of our information or technology systems may inadvertently result in unauthorized access to customer or proprietary information, or an inability to use our information technology systems to efficiently support business operations.

Additionally, we anticipate more frequent and sophisticated cyber-attacks along with more impactful regulatory oversight models. In addition, an increasing number of states require that customers be notified of unauthorized access, use or disclosure of their confidential information. Any such breach of confidential information could damage our reputation in the

Additionally, as the majority of our investments are longer-term fixed maturities that we typically hold until maturity, significant increases in interest rates widening of credit spreads or inactive markets associated with market downturns could cause a material temporary decline in the fair value of our fixed investment portfolio, even with regard to performing assets. These declines could cause a material increase in unrealized losses in our investment portfolio. Significant unrealized losses can substantially reduce our capital position and shareholders’ equity. It is possible that our investment in certain of these securities with unrealized losses may experience a default event and that a portion or all of that unrealized loss may not be recoverable. In that case, the unrealized loss will be realized, at which point we would take an impairment charge, reducing our net income.

We cannot be assured that any particular issuer, regardless of industry, will be able to make required interest and principal payments on a timely basis or at all. Significant downgrades of issuers could negatively impact our risk-based capital ratios, leading to potential downgrades by our rating agencies, potential reduction in future dividend capacity, and/or higher financing costs at the holding company should additional statutory capital be required.

Increases in interest rates could cause the fair value of securities within our bond portfolio to decline. A rise in interest rates could also result in certain policyholders surrendering their annuity policies for cash thereby potentially requiring our insurance subsidiaries to liquidate bonds if other sources of liquidity are not available to meet their obligations. In such a case, realized losses could result from such sales and could adversely affect our statutory income and results of operations.

The principal sources of our insurance subsidiaries’ liquidity are insurance premiums, as well as investment income, maturities, repayments and other cash flow from our investment portfolio. Our insurance subsidiaries are subject to various state statutory and regulatory restrictions applicable to insurance companies that limit the amount of cash dividends, loans and advances that those subsidiaries may pay to us, including laws establishing minimum solvency and liquidity thresholds. For example, in the states where our companies are domiciled, an insurance company generally may pay dividends only out of its unassigned surplus as reflected in its statutory financial statements filed in that state. Additionally, dividends paid by insurance subsidiaries are restricted based on regulations by their statestates of domicile. Accordingly, impairments in invested assets or a disruption in our insurance subsidiaries’ operations that reduces their capital or cash flow could limit or disallow payment of dividends to us, a principal source of our cash flow.

We can give no assurance that more stringent restrictions will not be adopted from time to time by states in which our insurance subsidiaries are domiciled, which could, under certain circumstances, significantly reduce dividends or other amounts paid to us by our subsidiaries. Although we do not anticipate changes, changes in these laws or regulations could constrain the ability of our subsidiaries to pay dividends or to advance or repay funds to us in sufficient amounts and at times necessary to meet our debt obligations and corporate expenses. Additionally, if our insurance subsidiaries were unable to obtain approval of our health premium rate increases in a timely manner from state insurance regulatory authorities, their profitability, and their ability to declare and distribute dividends to us could be negatively impacted. Limitations on the flow of dividends from our subsidiaries could limit our ability to service and repay debt or to pay dividends on our capital stock.

In the unlikely event that current sources of liquidity do not satisfy our needs, we may have to seek additional financing or raise capital. The availability and cost of additional financing or capital will depend on a variety of factors such as market conditions, the general availability of credit or capital, the volume of trading activities, the overall availability of credit to the insurance industry and our credit ratings and credit capacity. Additionally, customers, lenders or investors could develop a negative perception of our long- or short-term financial prospects if we were to incur large investment losses or if the level of our business activity decreaseswere to decrease due to a market downturn. Our access to funds may also be impaired if regulatory authorities or rating agencies take negative actions against us. If our internal sources of liquidity prove to be insufficient, we may not be able to successfully obtain additional financing on favorable terms or at all. As such, we may be forced to delay raising capital, issue shorter term securities than we prefer or bear an unattractive cost of capital which could decrease our profitability and significantly reduce our financial flexibility. As a result, our results of operations, financial condition and cash flows could be materially negatively affected.

We cannot predict the timing or substance of any future regulatory initiatives. In recent years, there has been increased scrutiny of insurance companies, including our insurance subsidiaries, by insurance regulatory authorities, which has included more extensive examinations and more detailed review of disclosure documents. These regulatory authorities may bring regulatory or other legal actions against us if, in their view, our practices, or those of our agents or employees, are improper. Such actions could result in substantial fines, penalties and/or prohibitions or restrictions on our business activities, and could have a material adverse effect on our business, results of operations or financial condition. Additionally, changes in the overall legal or regulatory environment may even absent any particular regulatory authority’s interpretation of an issue changing, cause us to change our views regarding the actions that we need to take from a legal or regulatory risk management perspective, thus necessitating changes to our practices that may, in some cases, limit our ability to grow, impact regulatory capital requirements, or otherwise negatively impact the profitability of our business.profitability.

Currently, the U.S. federal government does not directly regulate the business of insurance. However, the Dodd-Frank Wall Street Record and Consumer Protection Act of 2010 established a Federal Insurance Office (FIO) within, charged with monitoring systemic risk exposure in the Department of the Treasury, and the Affordable Care Actinsurance industry, and a Financial Stability Oversight Council (FSOC) created the, which serves to identify and respond to risks and emerging threats to U.S. financial systems. A Center for Consumer Information and Insurance Oversight (CCIIO), originally established under the Department of Health and Human Services, and subsequently transferred tois charged with overseeing implementation of the Centers for Medicare and Medicaid Services (CMS)Affordable Care Act (ACA). The creation of these insurance regulatory offices may indicate that the federal government intends to play a larger role in the direct oversight or regulation of the insurance industry. We cannot predict what impact, if any, the ongoing operations of the FIO, FSOC and CCIIO, as well as any other proposals or executive action for federal oversight or regulation of insurance could have on our business, results of operations or financial condition.

Our pending and future litigation could adversely affect us because of the costs of defending these cases, the costs of settlement or judgments against us, or changes in our operations that could result from litigation. Substantial legal liability in these or future legal actions could also have a material adverse financial effect or cause significant harm to our reputation, which, in turn, could materially harm our business and our business prospects.
