The Corporation maintains a defined benefit pension plan covering existing and former employees in the United States. The benefits under the pension plan are based on years of service and salary levels accrued as of December 31, 2009. In 2009, amendments were made to the defined benefit pension plan to freeze benefits accruing to employees at their respective years of service and salary levels obtained as of December 31, 2009. Certain employees in the United States are also eligible for post-retirement healthcare, life insurance, and other benefits. The Corporation accrues the present value of its obligations under employee future benefit plans and related costs, net of the present value of plan assets. The measurement date used to determine pension and other post-retirement benefit obligations and expense is December 31 of each year. The most recent actuarial valuation of the employee future benefit plans for funding purposes was as of January 1, 2021. The next actuarial valuation of the employee future benefit plans for funding purposes is expected to be performed as of January 1, 2022. The Corporation expects contributions of $nil to be paid to its defined benefit plans in 2022. The following tables reconcile the opening balances to the closing balances for the net defined benefit liability and its components for the two plans. The expense recognized in profit or loss is recorded in finance income (loss) and other. 20. Employee future benefits (cont'd):
