Pension, Post-Retirement and Other Long-term Employee Benefits
The Company has defined contribution plans, defined benefit pension plans, other post-retirement benefit plans, and other long-term employee benefit plans for certain of its employees in Canada and the US.
A defined contribution plan is a post-retirement benefit plan under which the Company pays fixed contributions into a separate entity and to which it will have no legal or constructive obligation to pay future amounts. The Company contributes to several state plans, multi-employer plans and insurance funds for individual employees that are considered defined contribution plans. Contributions to defined contribution pension plans are recognized as an employee benefit expense in earnings in the periods during which services are rendered by employees.
A defined benefit plan is a post-retirement benefit plan other than a defined contribution plan. For defined benefit pension plans, other post-retirement benefit plans and other long-term employee benefit plans, the benefits expense and the related obligations are actuarially determined on an annual basis by independent qualified actuaries using the projected unit credit method when the effects of discounting are material. Past service costs are recognized as an expense in earnings immediately following the introduction of, or changes to, a pension plan. Remeasurements, comprising actuarial gains and losses, the effect of the asset ceiling, the effect of minimum funding requirements and the return on plan assets (excluding amounts included in net interest expense) are recognized immediately in OCI, net of income taxes, and in deficit.
The asset or liability related to a defined benefit plan recognized in the balance sheet is the present value of the defined benefit obligation at the end of the reporting period, less the fair value of plan assets, together with adjustments for the asset ceiling and minimum funding liabilities. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability.
For funded plans, surpluses are recognized only to the extent that the surplus is considered recoverable. Recoverability is primarily based on the extent to which the Company can unilaterally reduce future contributions to the plan. Any reduction in the recognized asset is recognized in OCI, net of income taxes, and in deficit.
An additional liability is recognized based on the minimum funding requirement of a plan when the Company does not have an unconditional right to the plan surplus. The liability and any subsequent remeasurement of that liability is recognized in OCI, net of income taxes, and in deficit.
