The liability for the funded defined-benefit pension plans was $407 million at March 31, 2015 and $403 million at December 31, 2014. No cash contributions were made to the qualified pension plans during the three months ended March 31, 2015. Torchmark expects to make cash contributions to these plans during 2015 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, 2015, the combined value of the insurance policies and investments in the Rabbi Trust to support plan liabilities were $75 million, compared with $74 million at year-end 2014. 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 $72 million at March 31, 2015 and $71 million at December 31, 2014. |

Torchmark’s entire fixed-maturity and equity portfolio consisted of 1,589 issues at March 31, 2015 and 1,604 issues at December 31, 2014. The weighted average quality rating of all unrealized loss positions as of March 31, 2015 was BBB-. Although Torchmark’s fixed-maturity investments are available for sale, Torchmark’s management generally does not intend to sell and does not believe it will be required to sell any securities which are temporarily impaired before they recover due to the strong and stable cash flows generated by its insurance products. | |||||||||||||||||||||||||

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. Insurance marketing and underwriting is segmented by the types of insurance products offered: life, health, Medicare Part D, and annuity. Premium income for Medicare Part D health insurance is included with the premium for other health products in the Condensed Consolidated Statements of Operations. 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, 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. | ||||||||||||||||||||||||||||||||||
Torchmark provides coverage under the Medicare Part D prescription drug plan for Medicare beneficiaries. In accordance with GAAP, Part D premiums are recognized evenly throughout the year when they become due but benefit costs are recognized when the costs are incurred. Due to the design of the Part D product, premiums are evenly distributed throughout the year, but benefit costs are higher earlier in the year. As a result, under GAAP, benefit costs can exceed premiums in the first part of the year, but be less than premiums during the remainder of the year. In order to more closely match the benefit cost with the associated revenue for interim periods, Torchmark defers these excess benefits for segment reporting purposes. In addition, GAAP recognizes in each quarter a government risk-sharing premium adjustment consistent with the contract as if the quarter represented an entire contract period. These quarterly risk-sharing adjustments are removed in the segment analysis because the actual contract payments are based upon the experience of the full contract year, not the experience of interim periods. Torchmark expects its benefit ratio to be in line with pricing. Total premiums less total benefits will be the same for segment reporting purposes as they will be under GAAP for the full calendar year. The Company’s presentation results in the underwriting margin percentage in interim periods reflecting the expected margin percentage for the full year. These interim adjustments do not impact the full year results. | ||||||||||||||||||||||||||||||||||
An analysis of the adjustments for the difference in the interim results as presented for segment purposes and GAAP for Medicare Part D is as follows. | ||||||||||||||||||||||||||||||||||

During the first three months of 2014, Torchmark accrued for certain litigation cases in the net amount of $3.7 million ($2.4 million after tax) that were not directly related to its insurance operations. Additionally, Torchmark received $1.2 million ($752 thousand after tax) in settlement of litigation regarding investments. Torchmark removes these segment analysis amounts that do not relate to its core insurance operations. | ||||||||||||||||||||||||||||||||||

Low-income housing tax credits: As described in Note A, the FASB issued and Torchmark adopted new guidance concerning Investments-Equity Method and Joint Ventures: Accounting for Investments in Qualified Affordable Housing Projects (ASU 2014-01) as of January 1, 2015. The guidance replaces the effective-yield method of amortization with respect to investments in qualified affordable housing acquired after the date of adoption and, if certain conditions are present, provides for a proportional amortization method. The proportional amortization method allows an investor to amortize the cost of its investment based on the proportion of the tax credits received during the year to the total expected tax credits to be received over the life of the investment. The guidance further provides that the effective-yield method of amortization may continue to be used with respect to investments acquired before the date of adoption. Amortization, previously required to be recognized in the Condensed Consolidated Statements of Operations as a component of "Net investment income", will now be included in "Income tax expense." | ||||||||||||
Torchmark will continue to use the effective-yield method of amortization with respect to its guaranteed investments acquired prior to January 1, 2015, but will retroactively adopt the new guidance and apply the proportional method of amortization with respect to its non-guaranteed investments. The proportional method of amortization is consistent with Torchmark’s historical method of amortization. As a result, the only impact of the adoption is to reclassify amortization expense from “Net investment income” to “Income tax expense” with no impact on Torchmark's historical net income, cash flows, liquidity, or statutory earnings of its insurance subsidiaries. | ||||||||||||
The following table reflects a summary of the impact of the retrospectively adjusted balances on the Company's Condensed Consolidated Statements of Operations for the three months ended March 31, 2014: | ||||||||||||

Debt Issuance Costs: In April 2015, the FASB issued Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03), to simplify the presentation of debt issuance costs. The guidance will require companies to change the presentation of debt issuance costs in the financial statements by presenting such costs as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will still be reported as interest expense. The guidance is effective for fiscal years and interim periods beginning after December 15, 2015 with early adoption permitted. Torchmark adopted this ASU upon issuance. The Company accounts for debt issuance costs consistent with the new guidance and therefore there is no impact from the adoption. |
