Note 1 of the notes to the financial statements (page 78) of the Loblaw 2019 Annual Report reads as follows: For the purpose of impairment testing, assets, including right-of-use assets, are grouped together into the smallest group of assets that generate cash inflows from continuing use that are largely independent of cash inflows of other assets or groups of assets. This grouping is referred to as a cash generating unit (“CGU”). The Company has determined that each location is a separate CGU for purposes of impairment testing.
