As of June 30, 2016, PSNH had $1.2 billion in gross generation utility plant assets and related Accumulated Depreciation of $542.8 million. These generation assets are the subject of a divestiture agreement whereby PSNH agreed to divest of these generation assets. The NHPUC approved the divestiture agreement on July 1, 2016. The NHPUC is in the process of selecting an auction adviser to assist with the divestiture. Upon completion of the divestiture process, all remaining costs not recovered by the sale of these assets (stranded costs) will be recovered via bonds that will be secured by a non-bypassable charge or through recoveries in rates billed to PSNH's customers. See Note 8E, "Commitments and Contingencies – PSNH Generation Restructuring," for further information.
