The long-term rates of return on assets were selected from within the reasonable range of rates determined by (a) historical real returns for the asset classes covered by the investment policy and (b) projections of inflation over the long-term period during which benefits are payable to plan participants.

As of December 31, 2017 and 2016, “Other” consisted principally of cash and cash equivalents (approximately 1% of plan assets in each respective period).

The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy, where applicable:

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and money market funds and are classified as Level 1 investments.

Common Stock

Common stock is valued based on quoted market prices on an exchange in an active market and is classified as Level 1 investments.

Commingled Funds

Investments in the U.S. pension plan and foreign pension plan commingled funds represent pooled institutional investments, including primarily collective investment trusts. These commingled funds are not available on an exchange or in an active market and these investments are valued using their net asset value (“NAV”), which is generally based on the underlying asset values of the pooled investments held in the trusts.

As of December 31, 2017, the U.S. pension plan commingled funds included approximately 60 percent of investments in equity securities and 40 percent of investments in fixed income securities. As of December 31, 2017, foreign pension plan commingled funds included approximately 31 percent of investments in equity securities, 57 percent of investments in fixed income securities, and 12 percent of other non-related investments, primarily real estate.

Pooled Separate Accounts

Investments in the U.S. pension plan pooled separate accounts consist of insurance annuity contracts and are valued based on the reported unit value at year end. Units of the pooled separate account are not traded on an exchange or in an active market and these investments are valued using their NAV.

Insurance Contract

Investments in the foreign pension plan insurance contract are valued at the highest value available for the Company at year end, either the reported cash surrender value of the contract or the vested benefit obligation. Both the cash surrender value and the vested benefit obligation are determined based on unobservable inputs, which are contractually or actuarially determined, regarding returns, fees, the present value of the future cash flows of the contract and benefit obligations. The contract is classified as a Level 3 investment.

Diversified Equity Securities - Registered Investment Companies

Investments in the foreign pension plan diversified equity securities of registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available on an exchange or in an active market; however, the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market and are classified as Level 2 investments.

Fixed Income – Foreign Registered Investment Companies

Investments in the foreign pension plan fixed income securities of foreign registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available on an exchange or in an active market; however, the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market and are classified as Level 2 investments.

Real Estate

The foreign pension plan’s investment in real estate consists of an investment in a property fund. The fund’s underlying investments consist of real property, which are valued using unobservable inputs. The property fund is classified as a Level 3 investment

As of December 31, 2017 and 2016, the U.S. and foreign plans’ investments measured at fair value on a recurring basis were as follows:

Certain investments that are measured at fair value using the NAV per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented for these investments in the preceding tables are intended to permit reconciliation of the fair value hierarchies to the line items presented in the statements of net assets available for benefits.

Changes in the fair value of the foreign plans’ Level 3 investments during the years ended December 31, 2017 and 2016 were as follows:

			Insurance		Real Estate

Balance as of December 31, 2017		$	82,092	$	2,428	$	84,520

U.S. pension assets include Company common stock in the amounts of $1.5 million (3% of total U.S. plan assets) and $1.3 million (3% of total U.S. plan assets) as of December 31, 2017 and 2016, respectively.

During the second quarter of 2017, the Company’s U.S. pension plan offered a cash settlement to its vested terminated participants, which allowed them to receive the value of their pension benefits as a single lump sum payment. As payments from the U.S. pension plan for this cash out offering exceeded the service and interest cost components of the U.S. pension plan expense for the year ended December 31, 2017, the Company recorded a settlement charge of approximately $1.9 million. This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within AOCI on the balance sheet in proportion to the share of the projected benefit obligation that was settled by these payments. The gross pension benefit obligation was reduced by approximately $4.0 million as a result of these payments. The settlement charge was recognized through other expense, net, on the Company’s Consolidated Statements of Income.

Cash Flows

Contributions

The Company expects to make minimum cash contributions of $9.9 million to its pension plans ($4.6 million Domestic and $5.3 million Foreign) and approximately $0.4 million to its other postretirement benefit plan in 2018.

Estimated Future Benefit Payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:

							Other Post-
	Pension Benefits						Retirement
	Foreign		Domestic		Total		Benefits
2018	$	2,205	$	4,473	$	6,678	$	459

2023 to 2027		19,491		22,218		41,709		1,502

The Company maintains a plan under which supplemental retirement benefits are provided to certain officers. Benefits payable under the plan are based on a combination of years of service and existing postretirement benefits. Included in total pension costs are charges of $1.4 million, $0.9 million and $0.9 million for the years ended December 31, 2017, 2016 and 2015, respectively, representing the annual accrued benefits under this plan.

Defined Contribution Plan

The Company has a 401(k) plan with an employer match covering a majority of its domestic employees. The plan allows for and the Company previously paid a nonelective contribution on behalf of participants who have completed one year of service equal to 3% of the eligible participants’ compensation in the form of Company common stock. During the first quarter of 2017, the Company began matching both non-elective and elective 401(k) contributions in cash, rather than stock. Total Company contributions were $2.9 million, $2.7 million and $2.6 million for the years ended December 31, 2017, 2016 and 2015, respectively.
