- Definition

Carrying value of the regulatory asset that represents capitalized stranded costs that have been securitized (financed with debt) and are expected to be recoverable through a transition charge after one year (or beyond the operating cycle if longer). A transition charge is a charge approved by a regulator that allows deregulated utilities to recover investments in certain assets, such as power plants, over a transition period leading into a deregulated market.
