When a capital asset no longer contributes to the Corporation's ability to provide services, or the value of future economic benefits or service potential associated with the capital asset is less than its net carrying amount, the net carrying amount of the capital asset shall be written down to the capital asset's fair value or replacement value. Defined benefit post-retirement plan For employees who joined the Corporation prior to October 1, 2015, the Corporation provides certain non- pension post-retirement benefits consisting of extended health and other benefits. The defined benefit obligation is calculated based on the most recent actuarial valuation report prepared for accounting purposes. The Corporation applies the following policies: The Corporation accrues its obligations under defined benefit plans and the related costs when the benefits are earned through current service. The cost of retirement benefits earned by employees is actuarially determined using the projected benefit method pro-rated on service and management's best estimate of salary escalation, retirement ages of employees and expected health-care costs. Remeasurements and other items are composed of actuarial gains (losses) on the accrued benefit obligation and arise from differences between the actual and expected experience and from changes in the actuarial assumptions used to determine the accrued benefit obligation, past service costs and gains and losses arising from settlements and curtailments. Actuarial gains and losses arise when the accrued benefit obligations change during the year. The actuarial gains and losses and other remeasurements, including plan amendments, are recorded in the statement of changes in net assets (deficiency) when incurred.
