Hydro One Ltd. and Hydro One Inc. expect a one-time decrease in net income of up to approximately C$885 million from the impact of regulatory decisions on deferred tax asset.

The companies also anticipate an annual decrease in funds from operations in the range of C$50 million to C$60 million, according to a March 11 news release. The companies plan to file updated annual financial statements to reflect those developments.

The news follows the Ontario Energy Board's recent move to uphold its decision that a portion of the future savings from Hydro One Ltd.'s transition to an investor-owned company should be applied to reduce Hydro One Networks Inc.'s revenue requirement for 2017 and 2018.
