¹ As a result of the Company’s U.S. Domestication on January 1, 2019, and the associated change from a Canadian parent company to a U.S. parent company, the Company’s net investment hedge was no longer necessary from the domestication date onwards. As

of December 31, 2018, there was a $51 million net loss on hedge investments in foreign operations which is included in Foreign Currency Translation Adjustments.

² As of January 1, 2019, the Company discontinued hedge accounting related to the Company’s foreign exchange contracts. The Company still applies hedge accounting to the interest rate swaps related to long-term debt. As of December 31, 2020, the balance consisted of unrecognized loss on the Company’s interest rate swaps.
