23. Other employee benefits

Hudbay sponsors both other long-term employee benefit plans and non-pension post-employment benefits plans and uses a December 31 measurement date. These obligations relate mainly to commitments for post-retirement health benefits. Information about Hudbay's post-employment and other long-term employee benefits is as follows:

Hudbay reviews the assumptions used to measure other employee benefit costs (including the discount rate) on an annual basis.

The other employee benefit costs typically expose Hudbay to actuarial risks such as: interest rate risk, health care cost inflation risk and longevity risk.

Interest risk A decrease in the bond interest rate will increase the plan liabilities.

Health care cost inflation risk

The majority of the plan's benefit obligations are linked to health care cost inflation and higher inflation will lead to higher liabilities.

Longevity risk
The majority of the plans' benefit liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plans' liabilities. This is particularly significant for benefits subject to health care cost inflation where increases in inflation result in higher sensitivity to changes in life expectancy.

 

The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding other assumptions constant:

- If the discount rate is 50 basis points higher (lower), the defined benefit obligation would decrease by $5.7 million (increase by $6.4 million).

- If the health care cost assumption increases (decreases) by 1%, the defined benefit obligation would increase by $12.9 million (decrease by $10.4 million).

- If the life expectancy increases (decreases) by one year for both men and women, the defined benefit obligations would increase by $3.2 million (decrease by $3.2 million).

The average duration of the non-pension post-employment obligation at December 31, 2025 is 14.4 years (2024: 15.0 years).

This number can be broken down as follows:

- Active members: 22.3 years (2024: 23.0 years)

- Inactive members: 10.9 years (2024: 11.3 years)
