Employee questions submitted to Enbridgetransaction@spectraenergy.com

Q: We have received a variety of questions related to how the proposed transaction could affect the relationship between Enbridge Gas Distribution and Union Gas, including the impact on the companies’ operating structures, office locations, brands, company names as well as business operations, such as storage and transmission, call centres and shared services.

A: It’s important to remember that the focus of the proposed merger is to combine Enbridge Inc. and Spectra Energy Corp generally, but not their respective regulated utilities in Ontario. Therefore, there is no work underway that considers consolidating the structures, office locations, brands, company names or operations of the two utilities, which will continue to operate as separate companies after the closing of the proposed merger. Any opportunities flowing from the merger that generate efficiencies for the utilities would comply with the Affiliate Relationships Code, and would seek to enhance the benefit of shared services, similar to the way the utilities operate today.

Both utilities have rates and regulatory frameworks that will remain in effect through the end of 2018 and both utilities are working toward filing separate rate applications and incentive frameworks for the upcoming time periods with the Ontario Energy Board (OEB).

Q: Will the OEB have to weigh-in on the proposed merger and perhaps even approve it?

A: OEB approval is not required for the transaction, which is a proposed combination of Enbridge Inc. and Spectra Energy Corp, because Union Gas Limited is not a “significant asset” of Spectra Energy Corp, as defined in the Ontario Energy Board Act. In addition, the transaction does not contemplate any combination of Enbridge Gas Distribution and Union Gas Limited or any other change to their respective businesses.
