National Instrument 52-112 Non-GAAP and Other Financial Measures Disclosure (the “Instrument”) sets out specific disclosure requirements for non-GAAP financial measures, non-GAAP ratios, and other financial measures, which are capital management measures, supplementary financial measures, and total of segments measures, as defined in the Instrument (together the “specified financial measures”). The purpose of this Companion Policy (the “Policy”) is to explain how the provincial and territorial regulatory authorities interpret or apply certain provisions of the Instrument. This Policy includes explanations, discussions, and examples of various parts of the Instrument. This Policy contains, as Appendix A, a flow chart outlining the process for assessing specified financial measures. The flow chart is for illustrative purposes only and, in all cases, reference should be made to the precise language of the Instrument.
