Benefit Plans
22. Benefit Plans:
The Company sponsors two funded defined benefit pension plans that cover certain employees. Benefits for the plans are generally based on average final pay and years of service. The Company’s funding policy is to fund the minimum required contributions consistent with statutory requirements based on actuarial computations utilizing the projected unit credit method of calculation.
The Company sponsors an unfunded plan to provide health care benefits to certain retired employees. The plan pays a stated percentage of medical expenses reduced by deductibles and other coverage and obligations are paid out of the Company’s operations.
The Company uses a December 31 measurement date for all of its defined benefit pension and postretirement medical plans. Of the Company’s two defined benefit pension plans, the Eco Services Hourly Pension Plan was frozen to future accruals as of December 31, 2020, and the Eco Services Pension Equity Plan was frozen to future accruals as of December 31, 2016. The retiree healthcare plan was closed to new retirees effective July 1, 2017. The Company no longer has a defined benefit pension plan covering its employees at a foreign subsidiary, as the plan was converted to a defined contribution plan during the year ended December 31, 2021.

Expected return on assets 4.90  % 5.60  % 5.70  % 1.20  % 1.50  %
(1)    Includes only plans not frozen to benefit accruals for the respective periods.
The discount rate was determined by utilizing a yield curve model. The model develops a spot rate curve based on the yields available from a broad-based universe of high quality corporate bonds. The discount rate is then set as the weighted average spot rate, using the respective plan’s expected benefit cash flows as the weights.
The investment objective for the plans is to generate returns sufficient to meet future obligations. The strategy to meet the objective includes generating attractive returns using higher returning assets such as equity securities and balancing risk using less volatile assets such as fixed income securities. The plans invest in an allocation of assets across the two broadly-defined financial asset categories of equity and fixed income securities. The target allocations for the plan assets across the two U.S. plans are as follows: 35% equity securities and 65% fixed income investments for the Eco Services Pension Equity Plan; and 30% equity securities and 70% fixed income investments for the Eco Services Hourly Pension Plan.
The Company classifies plan assets based upon a fair value hierarchy (see Note 8 to these consolidated financial statements for further information). The classification of each asset within the hierarchy is based on the lowest level input that is significant to its measurement. The fair value hierarchy consists of three levels as follows:
•Level 1—Values are unadjusted quoted prices for identical assets and liabilities in active markets accessible at the measurement date. Active markets provide pricing data for trades occurring at least weekly and include exchanges and dealer markets. Level 1 assets primarily include investments in publicly traded equity securities and mutual funds. These securities (or the underlying investments of the funds) are actively traded and valued using quoted prices for identical securities from the market exchanges.
•Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are observable or can be corroborated by market data for the term of the instrument. Such inputs include market interest rates and volatilities,
spreads and yield curves. Level 2 assets primarily consist of fixed-income securities and commingled funds that are not actively traded or whose underlying investments are valued using observable marketplace inputs. The fair value of plan assets invested in fixed-income securities is generally determined using valuation models that use observable inputs such as interest rates, bond yields, low-volume market quotes and quoted prices for similar assets. Plan assets that are invested in commingled funds are valued using a unit price or net asset value (“NAV”) that is based on the underlying investments of the fund.
•Level 3—Certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date. Level 3 assets include investments covered by insurance contracts and real estate funds valued using significant unobservable inputs.
The following tables set forth by level, within the fair value hierarchy, plan assets at fair value:
