(1) The actuarial loss is due to changes in the actuarial assumptions used to determine the statutory severance obligations.


Significant assumptions for the calculation of the statutory severance obligations included the use of a discount rate of between 9.20% and 9.65% (2016 - between 9.75% and 9.85%) and rates of compensation increases between 8.0% and 10.0% (2016 - between 7.25% and 7.50%). A 1% increase in the discount rates would result in a corresponding decrease in the statutory severance obligations of $5.3 million, and a 1% decrease in the discount rates would result in a corresponding increase in the statutory severance obligations of $6.6 million. A 1% increase in the rates of compensation increases used would result in a corresponding increase in the statutory severance obligations of $6.6 million, and a 1% decrease in the rates of compensation increases used would result in a corresponding decrease in the statutory severance obligations of $5.4 million.

The cumulative amount of actuarial losses recognized in other comprehensive income as at December 31, 2017 was $22.1 million (January 1, 2017 - $22.0 million) which have been reclassified to retained earnings in the period in which they were recognized.

(b) Defined contribution plan:

During fiscal 2017, defined contribution expenses were $4.4 million (2016 - $3.4 million).

Provisions include estimated future costs of decommissioning and site restoration for certain assets located at the Company’s textile and sock facilities and a distribution centre in the U.S., for which the timing of settlement is uncertain, but has been estimated to be in excess of twenty years.
