As of March 31, 2016, PSNH had $1.2 billion in gross generation utility plant assets and related Accumulated Depreciation of $531.7 million. These generation assets are the subject of a divestiture agreement entered into on June 10, 2015 between Eversource, PSNH and key New Hampshire officials whereby PSNH agreed to divest these generation assets upon NHPUC approval. 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 other recovery mechanisms in rates billed to PSNH's customers. See Note 8E, "Commitments and Contingencies – PSNH Generation Restructuring," for further information.
