Other non-current liabilities: Decommissioning liabilities
A provision for decommissioning liabilities has been recorded for the Corporation’s head office building in Burnaby, British Columbia and is related to estimated site restoration obligations at the end of the lease term. The Corporation has made certain modifications to the leased building to facilitate the manufacturing and testing of its fuel cell products. Consequently, the site restoration obligations relate primarily to dismantling and removing various manufacturing and test equipment and restoring the infrastructure of the leased building to its original state of when the lease was entered into.
Due to the long-term nature of the liability, the most significant uncertainty in estimating the provision is the costs that will be incurred. The Corporation has determined a range of reasonably possible outcomes of the total costs for the head office building. In determining the fair value of the decommissioning liabilities, the estimated future cash flows have been discounted at 3.17% per annum (2022 – 3.41%).
The Corporation performed an assessment of the estimated cash flows required to settle the obligations for the building as of December 31, 2023. Based on the assessment, an increase of $449,000 in the provision (2022 - $nil) was recorded against decommissioning liabilities, in addition to accretion costs of $43,000 (2022 - $44,000) and the effect of movements in exchange rates of $40,000 (2022 - $(117,000)).
The net discounted amount of estimated cash flows required to settle the obligation for the building as of December 31, 2023 is $2,337,000 (2022 - $1,805,000) which is expected to be settled at the end of the lease term in 2025.

The Corporation maintained a defined benefit pension plan covering existing and former employees in the United States. The benefits under the pension plan were 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.
During the year ended December 31, 2023, the Corporation completed a settlement agreement with an external party to transfer 100% of its liability for the plan retiree population of the plan. On final settlement, $7,326,000 of the plan assets were distributed to this external party who then assumed the full liability of the retiree group. The Corporation also filed formal plan termination documents and once formal approval is obtained later in 2024, the Corporation anticipates settling the remaining plan liability through cash settlement and annuity purchases from the remaining plan assets.
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, 2023. The next actuarial valuation of the employee future benefit plans for funding purposes is expected to be performed as of January 1, 2024.
The Corporation expects contributions of $nil to be paid to its defined benefit plans in 2024.
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 statement of loss and comprehensive income (loss) is recorded in finance loss and other (note 26).
