Pension and Other Post-retirement Benefits |
10. | Pension and Other Post-retirement Benefits
The Company provides retirement benefits for all U.S. employees including benefits for employees of previously owned businesses which were earned up to the date of sale. The Company also has two foreign pension plans, neither of which is material to the Company’s financial position. The Company has a defined contribution plan which matches 100 percent of the first one percent of contributions made by participating employees and matches 50 percent of the next five percent of employee contributions. The Company also has defined contribution plans for certain hourly employees which provide for matching Company contributions. The Company also has a defined benefit plan for salaried employees and its non-union hourly workforce. In 2009, the Company announced U.S. employees hired after January 1, 2010, would not participate in the defined benefit plan, and benefit accruals for the majority of current salaried and hourly employees sunset on December 31, 2014. Beginning in 2015, an additional Company contribution is being made to the defined contribution plan in lieu of benefits earned in a defined benefit plan. The Company also has defined benefit and contribution plans for certain union hourly employees. The Company has unfunded defined-benefit post-retirement plans covering certain hourly and salaried employees that provide medical and life insurance benefits from retirement to age 65. Certain hourly employees retiring after January 1, 1996, are subject to a maximum annual benefit and salaried employees hired after December 31, 1993, are not eligible for post-retirement medical benefits. As of December 31, 2015, the Company changed the method used to estimate the service and interest components of net periodic benefit cost for its pension plan and its post-retirement benefit plan. This change compared to the previous method resulted in a $7.7 million and $7.1 million decrease in the service and interest components for pension cost in 2017 and 2016, respectively compared to 2015. Historically, the Company estimated the service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. The Company has elected to utilize an approach that discounts the individual expected cash flows underlying the service cost and interest cost using the applicable spot rates derived from the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change was made to provide a more precise measurement of service and interest costs by improving the correlation between the projected benefit cash flows to the corresponding spot yield curve rates. This change did not affect the measurement of the total benefit obligations but reduced the service and interest cost for the pension plan. The Company accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and accordingly accounted for it prospectively beginning January 1, 2016.

The estimated net actuarial loss and prior service cost for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2018 are $18.7 million and $(0.4) million, respectively. The estimated net actuarial loss and prior year service cost for the post-retirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2018 are $(0.1) million and $(0.4) million, respectively. As permitted under ASC 715, the amortization of any prior service cost was previously determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the plan. Beginning in 2015 the amortization occurs over the average remaining life expectancy of participants expected to receive benefits under the plan as permitted under ASC 715. The 2017 and 2016 after tax adjustments for additional minimum pension liability resulted in other comprehensive gain (loss) of $12.1 million and $(9.0) million, respectively. Actuarial assumptions used to determine benefit obligations at December 31 are as follows:
|  | Pension Benefits |  |  | Post-retirement Benefits |
|  | 2017 |  |  | 2016 |  |  | 2017 |  |  | 2016 |
Discount rate |  |  | 3.65 | % |  |  | 4.15 | % |  |  | 3.79 | % |  |  | 4.33 | %
Average salary increases |  |  | n/a |  |  |  | 4.00 | % |  |  | n/a |  |  |  | n/a |
Actuarial assumptions used to determine net periodic benefit cost for the year ended December 31 are as follows:
|  | Pension Benefits |  |  | Post-retirement Benefits |
Years ended December 31 |  | 2017 |  |  | 2016 |  |  | 2015 |  |  | 2017 |  |  | 2016 |  |  | 2015 |

Assumptions In developing the expected long-term rate of return on plan assets assumption, the Company evaluated its pension plan’s target and actual asset allocation and expected long-term rates of return of equity and bond indices. The Company also considered its pension plan’s historical ten-year and 25-year compounded annualized returns of 6.3 percent and 9.2 percent, respectively. Assumed health care cost trend rates Assumed health care cost trend rates as of December 31 are as follows:
|  | 2017 |  |  | 2016 |
Health care cost trend rate assumed for next year |  |  | 6.50 | % |  |  | 6.50 | %
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) |  |  | 5.00 | % |  |  | 5.00 | %
Year that the rate reaches the ultimate trend rate |  |  | 2021 |  |  |  | 2021 |
A one-percentage-point change in the assumed health care cost trend rates would not result in a material impact on the Company’s consolidated financial statements. Plan Assets The Company’s pension plan weighted asset allocations as of December 31 by asset category are as follows:
Asset Category |  | 2017 |  |  | 2016 |
Equity securities |  |  | 45 | % |  |  | 48 | %
Debt securities |  |  | 43 |  |  |  | 37 |

The short-term investments included in the Company’s plan assets consist of cash and cash equivalents. The fair value of the remaining categories of the Company’s plan assets are valued as follows: equity securities are valued using the closing stock price on a national securities exchange, which reflects the last reported sales price on the last business day of the year; fixed income securities are valued using institutional bond quotes, which are based on various market and industry inputs; mutual funds and real estate funds are valued using the net asset value of the fund, which is based on the fair value of the underlying securities; and private equity investments are valued at the estimated fair value at the previous quarter end, which is based on the proportionate share of the underlying portfolio investments. The following table presents a reconciliation of the fair value measurements using significant unobservable inputs (Level 3) as of December 31, 2017 and 2016 (dollars in millions):

The Company’s investment policies employ an approach whereby a diversified blend of equity and bond investments is used to maximize the long-term return of plan assets for a prudent level of risk. Equity investments are diversified across domestic and non-domestic stocks, as well as growth, value, and small to large capitalizations. Bond investments include corporate and government issues, with short-, mid- and long-term maturities, with a focus on investment grade when purchased. The Company’s target allocation to equity managers is between 45 to 55 percent with the remainder allocated primarily to bonds, real estate, private equity managers and cash. Investment and market risks are measured and monitored on an ongoing basis through regular investment portfolio reviews, annual liability measurements and periodic asset/liability studies. The Company’s actual asset allocations are in line with target allocations. The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate. There was no Company stock included in plan assets at December 31, 2017. Cash Flows The Company was not required to make a contribution in 2017 but elected to make a $30 million voluntary contribution. The Company is not required to make a contribution in 2018. Estimated Future Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:
Years ending December 31 (dollars in millions) |  | Pension Benefits |  |  | Post-retirement Benefits |
2018 |  | $ | 60.5 |  |  | $ | 0.3 |
2019 |  |  | 66.6 |  |  |  | 0.4 |
