The Company maintains defined benefit retirement plans, primarily for certain domestic employees, as presented below. All plans are frozen to new entrants, with the exception of the executive supplemental plan. Benefits are based primarily on years of service and earnings of the employee.

The significant assumptions used in the measurement of the projected benefit obligation and net periodic benefit cost primarily include the discount rate, rate of compensation increase and expected long-term return on plan assets. Weighted-average assumptions for the projected benefit obligation follows:

The weighted-average cash balance interest crediting rate for the Company's cash balance defined benefit plans was 4.0% for the years ended December 31, 2021, 2020 and 2019.

The Company considers several factors in determining the long-term rate of return for plan assets. Asset-class return expectations are set using a combination of empirical and forward-looking analyses. Capital market assumptions for the composition of the Company’s asset portfolio are intended to capture the behavior of asset classes observed over several market cycles. The Company also looks to historical returns for reasonableness and appropriateness.

The Company employs a liability driven investment approach whereby plan assets are invested primarily in fixed income investments to match the changes in the projected benefit obligation of funded plans related to changes in interest rates. Risk tolerance is established through careful consideration of projected benefit obligations, plan funded status and the Company’s other obligations and strategic investments.

The established target allocation is 88.0% fixed income securities and 12.0% equity securities. Fixed income investments are diversified across U.S. treasury, long and intermediate duration and high yield bonds. Equity investments are diversified across large capitalization U.S. and international stocks. Investment risk is measured and monitored on an ongoing basis through investment portfolio reviews, annual projected benefit liability measurements and asset/liability studies.
