The Company provides the Executives Plan for certain current and former senior officers, the Retirement Program for eligible employees in Canada, and the Mexico Plans for eligible employees in Mexico, each of which are considered defined benefit plans under IAS 19 - Employee Benefits. The funded status of the plans are based on actuarial valuations performed as at December 31, 2021. The plans operate under similar regulatory frameworks and generally face similar risks.

The Executives Plan pension formula is based on final average earnings in excess of the amounts payable from the registered plan. Assets for the Executives Plan consist of deposits on hand with regulatory authorities that are refundable when benefit payments are made or on the ultimate wind-up of the plan.

The Company provides a Retirement Program for certain eligible employees that provides a lump-sum payment upon retirement. The payment is based on age and length of service at retirement. An eligible employee is entitled to a benefit if they have completed at least 10 years of service as a permanent employee and are 57 years of age or older. The Retirement Program is not funded.

The Mexico Plans provide a lump-sum payment upon retirement. The payment is based on age and length of service at retirement. Eligible employees are entitled to a benefit if they have completed 15 years of service as a permanent employee and are 60 years of age or older. The Mexico Plans are not funded.

Other significant actuarial assumptions used in measuring the Company's Retirement Program defined benefit obligations as at December 31, 2021 and December 31, 2020 include assumptions of the expected retirement age of participants.

The following table sets out the effect of changes in significant actuarial assumptions on the Company's defined benefit obligations:

The summary of the effect of changes in significant actuarial assumptions was prepared using the same methods and actuarial assumptions as those used for the calculation of the Company's defined benefit obligation related to the Executives Plan, the Retirement Program and the Mexico Plans as at the end of the fiscal year, except for the change in the single actuarial assumption being evaluated. The modification of several actuarial assumptions at the same time could lead to different results.

In addition to its defined benefit pension plans, the Company maintains two defined contribution plans – the Basic Plan and the Supplemental Plan. Under the Basic Plan, Agnico Eagle contributes 5.0% of certain employees’ base employment compensation to a defined contribution plan. In 2021, $17.0 million (2020 – $13.6 million) was contributed to the Basic Plan, $0.2 million of which related to contributions for key management personnel (2020 – $0.2 million). The Company also maintains the Supplemental Plan for designated executives at the level of Vice-President or above. The Supplemental Plan is funded by the Company through notional contributions equal to 10.0% of the designated executive’s earnings for the year (including salary and short-term bonus). In 2021, the Company made $1.5 million (2020 – $1.3 million) in notional contributions to the Supplemental Plan, $0.9 million (2020 – $1.0 million) of which related to contributions for key management personnel. The Company’s liability related to the Supplemental Plan is $10.6 million at December 31, 2021 (2020 - $11.5 million). At retirement date, the notional account balance is converted to a pension payable in five annual installments.
