Electric Properties

BVES’s properties are located in the Big Bear area of San Bernardino County, California. As of December 31, 2024, BVES owned and operated approximately 87.8 miles of overhead 34.5 kilovolt (kv) sub-transmission lines (21.94 circuit miles are insulated), 6.49 miles of underground 34.5 kv sub-transmission lines, 494.36 miles of overhead 4.16 kv or 2.4 kv distribution lines (45.01 circuit miles are insulated), 114.52 miles of underground cable, 13 sub-stations and a natural gas-fueled 8.4 MW peaking generation facility. BVES also has franchises, easements and other rights of way for the purpose of constructing and using poles, wires and other appurtenances for transmitting electricity.

Adjudicated and Other Water Rights

GSWC owns groundwater and surface water rights in California. Groundwater rights are further subject to classification as either adjudicated or unadjudicated rights. Adjudicated rights have been established through comprehensive litigation in the courts, and the annual extraction quantities and use of the adjudicated rights are often subject to the provisions of the judgment for that particular groundwater basin. Additionally, as a result of the adjudication, many of these groundwater basins are managed by a watermaster that is charged with enforcing the provisions of the judgment, which may include determining operating safe yields based on the water supply conditions of the groundwater basin.

GSWC actively manages its adjudicated groundwater rights portfolio with the goal of optimizing and making this source of supply sustainable. Unadjudicated rights are subject to further regulation by the State Water Resources Control Board (“SWRCB”) and the California Department of Water Resources. Surface water rights are quantified and managed by the SWRCB, unless the surface water rights originated prior to 1914. As of December 31, 2024, GSWC had adjudicated groundwater rights and surface water rights of 70,794 and 11,335 acre-feet per year, respectively. GSWC also has a number of unadjudicated groundwater rights, which have not been quantified, but are typically measured by historical usage.

Office Buildings

GSWC owns its general headquarters facility in San Dimas, California. GSWC also owns and leases customer service offices and office space throughout California. BVES owns office space in California. ASUS leases office facilities in Virginia, North Carolina and Maryland, and owns service centers in Florida, Maryland, South Carolina, Virginia, Texas, North Carolina and Kansas.

Mortgage and Other Liens

As of December 31, 2024, neither AWR, GSWC, BVES, ASUS, nor any of its subsidiaries, had any mortgage debt or liens securing indebtedness outstanding. Under the terms of certain debt instruments, AWR, GSWC and BVES are prohibited from issuing any secured debt, without providing equal and ratable security to the holders of this existing debt.

Condemnation of Properties

The laws of the state of California provide for the acquisition of public utility property by governmental agencies through their power of eminent domain, also known as condemnation, where doing so constitutes a more necessary use. In addition, these laws provide that the owner of utility property (i) may contest whether the condemnation is actually necessary, and (ii) is entitled to receive the fair market value of its property if the property is ultimately taken.
