Employee Benefit Plans

Pension Benefits

The Company has defined benefit pension retirement plans covering a substantial number of employees. The defined benefits for salaried employees generally are based on years of service and the employee's level of compensation during specified periods of employment. Defined benefit plans covering hourly employees generally provide benefits of stated amounts for each year of service. The multiemployer pension plans ("MEPPs") in which the Company participates provide benefits to certain unionized employees. The Company's funding policy for qualified plans is consistent with statutory regulations and customarily equals the amount deducted for income tax purposes. Periodic voluntary contributions are made, as recommended, by the Company's Pension Committee. The Company's policy is to amortize prior service costs of defined benefit pension plans over the average future service period of active plan participants.

For most U.S. defined benefit pension plans and a majority of international defined benefit pension plans, accrued service is no longer granted. In place of these plans, the Company has established defined contribution pension plans providing for the Company to contribute a specified matching amount for participating employees' contributions to the plan. For U.S. employees, this match is made on employee contributions up to 4% of their eligible compensation. Additionally, the Company may provide a discretionary contribution for eligible employees. There have been no discretionary contributions provided for the years 2015, 2014 and 2013. For non-U.S. employees, this match is up to 6% of eligible compensation with an additional 2% going towards insurance and administrative costs.

Net periodic pension cost ("NPPC") for U.S. and international pension plans for 2015, 2014 and 2013 is as follows:

The Company's estimate of expected contributions to be paid in 2016 for the U.S. and international defined benefit plans are $2.1 million and $21.6 million, respectively.

Future Benefit Payments

The expected benefit payments for defined benefit plans over the next 10 years are as follows:

(In millions)	2016		2017		2018		2019		2020		2021-2025
U.S. Plans	$	19.1	$	19.1	$	18.9	$	18.7	$	18.8	$	94.8
International Plans	39.7		40.3		41.2		42.6		44.5		244.4

Net Periodic Pension Cost and Defined Benefit Pension Obligation Assumptions

The weighted-average actuarial assumptions used to determine the NPPC for 2015, 2014 and 2013 were as follows:

	U.S. Plans December 31						International Plans December 31						Global Weighted-Average December 31
	2015		2014		2013		2015		2014		2013		2015		2014		2013
Discount rates	3.9	%	4.7	%	3.8	%	3.7	%	4.7	%	4.3	%	3.7	%	4.7	%	4.2	%
Expected long-term rates of return on plan assets	7.5	%	7.5	%	7.5	%	6.8	%	6.8	%	6.6	%	7.0	%	7.0	%	6.8	%
Rates of compensation increase	3.0	%	3.0	%	3.0	%	3.2	%	3.4	%	2.8	%	3.2	%	3.4	%	2.8	%

The expected long-term rates of return on plan assets for the 2016 NPPC are 7.25% for the U.S. plans and 6.5% for the international plans. The expected global long-term rate of return on assets for 2016 is 6.7%.

The weighted-average actuarial assumptions used to determine the defined benefit pension plan obligations at December 31, 2015 and 2014 were as follows:

	U.S. Plans				International Plans				Global Weighted-Average
	December 31				December 31				December 31
	2015		2014		2015		2014		2015		2014
Discount rates	4.2	%	3.9	%	3.8	%	3.7	%	3.9	%	3.7	%
Rates of compensation increase	3.0	%	3.0	%	3.2	%	3.2	%	3.2	%	3.2	%

The U.S. discount rate was determined using a yield curve that was produced from a universe containing approximately 700 U.S. dollar-denominated, AA-graded corporate bonds, all of which were noncallable (or callable with make-whole provisions), and excluding the 10% of the bonds with the highest yields and the 10% with the lowest yields within each maturity group. The discount rate was then developed as the level-equivalent rate that would produce the same present value as that using spot rates to discount the projected benefit payments. For international plans, the discount rate is aligned to corporate bond yields in the local markets, normally AA-rated corporations. The process and selection seeks to approximate the cash inflows with the timing and amounts of the expected benefit payments.

The Company has changed the method utilized to estimate the 2016 service cost and interest cost components of NPPC for defined benefit pension plans. The more precise application of discount rates for measuring both service costs and interest costs employs yield curve spot rates on a year-by-year expected cash flow basis, using the same yield curves that the Company has previously used. This change in method represents a change in accounting estimate and will be accounted for in the period of change.

Accumulated Benefit Obligation

The accumulated benefit obligation for all defined benefit pension plans at December 31, 2015 and 2014 was as follows:

	U.S. Plans				International Plans
	December 31				December 31
(In millions)	2015		2014		2015		2014
Accumulated benefit obligation	$	307.4	$	325.3	$	894.8	$	1,043.2

Plans with Accumulated Benefit Obligation in Excess of Plan Assets

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets at December 31, 2015 and 2014 were as follows:

	U.S. Plans				International Plans
	December 31				December 31
(In millions)	2015		2014		2015		2014
Projected benefit obligation	$	297.5	$	314.9	$	876.9	$	1,032.1
Accumulated benefit obligation	297.5		314.9		871.9		1,026.0
Fair value of plan assets	198.8		222.3		731.6		771.8

The asset allocations attributable to the Company's U.S. defined benefit pension plans at December 31, 2015 and 2014, and the long-term target allocation of plan assets, by asset category, are as follows:

	Target  Long-Term Allocation	Percentage of Plan Assets at December 31
U.S. Plans Asset Category		2015		2014
Domestic equity securities	32%-42%	37.2	%	39.1	%
International equity securities	15%-25%	18.5	%	18.2	%
Fixed income securities	28%-38%	32.6	%	30.3	%
Cash and cash equivalents	Less than 5%	1.7	%	3.1	%
Other	5%-15%	10.0	%	9.3	%

Plan assets are allocated among various categories of equities, fixed income securities and cash and cash equivalents with professional investment managers whose performance is actively monitored. The primary investment objective is long-term growth of assets in order to meet present and future benefit obligations. The Company periodically conducts an asset/liability modeling study and accordingly adjusts investments among and within asset categories to ensure the long-term investment strategy is aligned with the profile of benefit obligations.

The Company reviews the long-term expected return on asset assumption on a periodic basis taking into account a variety of factors including the historical investment returns achieved over a long-term period, the targeted allocation of plan assets and future expectations based on a model of asset returns for an actively managed portfolio. The model simulates 1,000 different capital market results over 20 years. For 2016 and 2015, the expected return-on-asset assumption for U.S. plans was 7.25% and 7.5%, respectively.

The U.S. defined benefit pension plans assets include 450,000 shares of the Company's common stock at both December 31, 2015 and 2014, valued at $3.5 million and $8.5 million, respectively. These shares represented 1.7% and 3.6% of total plan assets at December 31, 2015 and 2014, respectively. Dividends paid to the pension plans on the Company's common stock amounted to $0.4 million in 2015, 2014 and 2013.

The asset allocations attributable to the Company's international defined benefit pension plans at December 31, 2015 and 2014 and the long-term target allocation of plan assets, by asset category, are as follows:

International Plans Asset Category	Target Long-Term Allocation		Percentage of Plan Assets at December 31
			2015		2014
Equity securities	32.5	%	33.7	%	36.9	%
Fixed income securities	42.5	%	43.3	%	45.3	%
Cash and cash equivalents	—		0.3	%	0.3	%
Other (a)	25.0	%	22.7	%	17.5	%

(a) Investments within this caption include diversified growth funds, real estate funds and infrastructure funds.

Plan assets at December 31, 2015 in the U.K. defined benefit pension plan amounted to approximately 95% of the international pension assets. These assets are allocated among various categories of equities, fixed income securities and cash and cash equivalents with professional investment managers whose performance is actively monitored. The primary investment objective is long-term growth of assets in order to meet present and future benefit obligations. The Company periodically conducts asset/liability modeling studies and accordingly adjusts investment amounts within asset categories to ensure the long-term investment strategy is aligned with the profile of benefit obligations.

For the international long-term rate of return assumption, the Company considered the current level of expected returns in risk-free investments (primarily government bonds), the historical level of the risk premium associated with other asset classes in which the portfolio is invested and the expectations for future returns of each asset class and plan expenses. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on assets. The 2016 and 2015, the expected return on asset assumption for the U.K. plan was 6.6% and 6.8%, respectively. The remaining international pension plans, with assets representing approximately 5% of the international pension assets, are under the guidance of professional investment managers and have similar investment objectives.

Following is a description of the valuation methodologies used for the plans' investments measured at fair value:

• Level 1 Fair Value Measurements—Investments in interest-bearing cash are stated at cost, which approximates fair value. The fair values of money market accounts and certain mutual funds are based on quoted net asset values of the shares held by the plan at year-end. The fair values of domestic and international stocks and corporate bonds, notes and convertible debentures are valued at the closing price reported in the active market on which the individual securities are traded.

• Level 2 Fair Value Measurements—The fair values of investments in mutual funds for which quoted net asset values in an active market are not available are valued by the investment advisor based on the current market values of the underlying assets of the mutual fund based on information reported by the investment consistent with audited financial statements of the mutual fund. Further information concerning these mutual funds may be obtained from their separate audited financial statements. Investments in U.S. Treasury notes and collateralized securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings.

• Level 3 Fair Value Measurements—Real estate limited partnership interests are valued by the general partners based on the underlying assets. The limited partnership interests are valued using unobservable inputs and have been classified within Level 3 of the fair value hierarchy.

Multiemployer Plans

The Company, through the Harsco Metals & Minerals Segment, contributes to several MEPPs under the terms of collective-bargaining agreements that cover union-represented employees, many of whom are temporary in nature. The Company's total contributions to MEPPs were $2.5 million, $3.0 million and $17.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. The decrease in contributions by the Company for 2014 and 2015 primarily relates to the consummation of the Infrastructure Transaction. See Note 3, Acquisitions and Dispositions, for additional information related to the Infrastructure Transaction.
