Why similar U.S and Canadian risk profiles yield varied rate-making results.
of establishing an appropriate ROE can’t be trusted to an automatic adjustment mechanism or a generic formula dependent on government bond yields. The apparent lesson for U.S. regulators is that they should continue to rely on more traditional methods such as DCF models and ERP models to estimate the range of reasonable returns on equity, and continue applying judgment as market circumstances dictate. Thus far, a generic formula hasn’t proven capable of producing fair and reasonable results under different financial market conditions, unless the results are tempered by frequent review and the judgment and expertise of the regulator, which might defeat the original purpose of adopting a formulaic approach in order to achieve regulatory efficiency. The jury still is out on these newer formulas, but lessons of the past decade illustrate that ROE can’t be placed on auto-pilot.
