Retirement Benefits [Abstract] |
Employee Benefit Plans | EMPLOYEE BENEFIT PLANS Certain subsidiaries of the Company are sponsors or administrators of both qualified and non-qualified defined benefit pension plans (“Pension Plans”). The largest of these plans is a non-contributory qualified defined benefit pension plan sponsored by RGA Reinsurance Company (“RGA Reinsurance”) that covers U.S. employees. The benefits under the Pension Plans are generally based on years of service and compensation levels. The Company also provides select health care and life insurance benefits for certain retired employees. The health care benefits are provided through a self-insured welfare benefit plan. Employees become eligible for these benefits if they meet minimum age and service requirements. The retiree’s cost for health care benefits varies depending upon the credited years of service. Effective January 1, 2017, employees hired in the U. S. are not eligible for retiree health care benefits. The effect of the amendment was recorded in 2016 in AOCI and is being amortized through prior service cost. Virtually all retirees, or their beneficiaries, contribute a portion of the total cost of postretirement health benefits. Prepaid benefit costs and accrued benefit liabilities are included in other assets and other liabilities, respectively, in the Company’s consolidated balance sheets. A December 31 measurement date is used for all of the defined benefit and postretirement plans. The status of these plans as of December 31, 2018 and 2017 is summarized below (dollars in thousands):

During 2019, the Company expects to contribute $16.3 million and $1.5 million to the pension plans and other benefit plans, respectively. The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (dollars in thousands):
|  | Pension Benefits |  | Other Benefits
2019 |  | $ | 9,977 |  |  | $ | 1,528 |
2020 |  | 12,013 |  |  | 1,835 |
2021 |  | 11,663 |  |  | 2,209 |
2022 |  | 14,229 |  |  | 2,633 |
2023 |  | 14,128 |  |  | 3,009 |
2024-2028 |  | 77,832 |  |  | 20,359 |
Assumptions Weighted average assumptions used to determine the accumulated benefit obligation and net benefit cost or income were as follows:
|  | Pension Benefits |  | Other Benefits
|  | 2018 |  | 2017 |  | 2016 |  | 2018 |  | 2017 |  | 2016
Discount rate used to determine benefit obligation |  | 4.02 | % |  | 3.40 | % |  | 3.80 | % |  | 4.17 | % |  | 3.56 | % |  | 4.10 | %
Discount rate used to determine net benefit cost or income |  | 3.41 | % |  | 3.81 | % |  | 3.95 | % |  | 3.56 | % |  | 4.10 | % |  | 4.43 | %
Expected long-term rate of return on plan assets |  | 7.35 | % |  | 7.35 | % |  | 7.35 | % |  | — | % |  | — | % |  | — | %
Rate of compensation increases |  | 4.17 | % |  | 4.16 | % |  | 4.08 | % |  | — | % |  | — | % |  | — | %
The expected rate of return on plan assets is based on anticipated performance of the various asset sectors in which the plan invests, weighted by target allocation percentages. Anticipated future performance is based on long-term historical returns of the plan assets by sector, adjusted for the long-term expectations on the performance of the markets. While the precise expected return derived using this approach may fluctuate from year to year, the policy is to hold this long-term assumption constant as long as it remains within reasonable tolerance from the derived rate. This process is consistent for all plan assets as all the assets are invested in mutual funds. The assumed health care cost trend rates used in measuring the accumulated non-pension post-retirement benefit obligation were as follows:
|  | December 31,
|  | 2018 |  | 2017
Pre-Medicare eligible claims |  | 8% down to 5% in 2024 |  | 9% down to 5% in 2024
Medicare eligible claims |  | 8% down to 5% in 2024 |  | 9% down to 5% in 2024
Plan Assets Target allocations of U.S. qualified pension plan assets are determined with the objective of maximizing returns and minimizing volatility of net assets through adequate asset diversification and partial liability immunization. Adjustments are made to target allocations based on the Company’s assessment of the effect of economic factors and market conditions. The target allocations for plan assets are 60% equity securities and 40% debt securities as of December 31, 2018 and 2017. The Company’s plan assets are primarily invested in mutual funds. The mutual funds include holdings of S&P 500 securities, large-cap securities, mid-cap securities, small-cap securities, international securities, corporate debt securities, U.S. and other government securities, mortgage-related securities and cash. Equity and debt securities are exposed to various risks, such as interest rate risk, credit risk and overall market volatility. Due to the level of risk associated with certain investment securities, changes in the values of investment securities will occur and any change would affect the amounts reported in the financial statements. The fair values of the Company’s qualified pension plan assets as of December 31, 2018 and 2017 are summarized below (dollars in thousands):

As of December 31, 2018 and 2017, the Company classified all of its qualified pension plan assets in the Level 1 category as quoted prices in active markets are available for these assets. See Note 6 – “Fair Value of Asset and Liabilities” for additional detail on the fair value hierarchy. Savings and Investment Plans Certain subsidiaries of RGA also sponsor savings and investment plans under which a portion of employee contributions are matched. Subsidiary contributions to these plans were $15.3 million, $14.2 million and $9.9 million in 2018, 2017 and 2016, respectively.
