FLI is typically identified by words such as “anticipate”, “expect”, “project”, “estimate”, “forecast”, “plan”, “intend”, “target”, “believe”, “likely” and similar words suggesting future outcomes or statements regarding an outlook.

Although we believe that the FLI is reasonable based on the information available today and processes used to prepare it, such statements are not guarantees of future performance and you are cautioned against placing undue reliance on FLI.

All FLI in this news release is expressly qualified in its entirety by these cautionary statements. This presentation makes reference to non-GAAP measures, including ACFFO and ACFFO per share. ACFFO is defined as cash flow provided by operating activities before changes in operating assets and liabilities (including changes in environmental liabilities) less distributions to non-controlling interests and redeemable non-controlling interests, preference share dividends and maintenance capital expenditures, and further adjusted for unusual, non-recurring or non-operating factors. Management of Enbridge believes the presentation of these measures gives useful information to investors and shareholders as they provide increased transparency and insight into the performance of Enbridge. Management of Enbridge uses ACFFO to assess performance and to set its dividend payout target. These measures are not measures that have a standardized meaning prescribed by generally accepted accounting principles in the United States of America (U.S. GAAP) and may not be comparable with similar measures presented by other issuers. Additional information on Enbridge’s use of non-GAAP measures can be found in Enbridge’s Management’s Discussion and Analysis (MD&A) available on Enbridge’s website and www.sedar.com.
