Effective July 1, 2019, the Company revised the estimated useful lives of its yarn-spinning manufacturing equipment based on a re-assessment of their expected use to the Company and recent experience of their economic lives. These assets, which were previously being depreciated on a straight-line basis over 10 years, are now depreciated on a straight-line basis over 15 to 20 years depending on the nature of the equipment. The change in estimate was made on a prospective basis and resulted in a reduction of depreciation of approximately $8.5 million, of which approximately $1 million was included in cost of sales for the year ended December 29, 2019 as depreciation related to manufacturing equipment is initially included in the cost of inventories, and is charged to cost of sales when the related inventories have been sold. For fiscal 2020, the change in estimate is expected to result in a reduction of depreciation included in net earnings of approximately $17 million.

Assets not yet utilized in operations include expenditures incurred to date for plant expansions which are still in process and equipment not yet placed into service as at the end of the reporting period.

As at December 29, 2019, there were contractual purchase obligations outstanding of approximately $21.2 million for the acquisition of property, plant and equipment compared to $24.8 million as of December 30, 2018.
