American States Water Company Announces Approval by CPUC of Rate Increases


    SAN DIMAS, Calif.--(BUSINESS WIRE)--Jan. 4, 2007--American States
Water Company (NYSE:AWR) announced that the California Public
Utilities Commission ("CPUC") approved rate increases for all water
service areas of its Golden State Water Company ("GSWC") unit. The
authorized rate increases are effective January 1, 2007 and will
provide GSWC additional annual revenues of approximately $5,978,000 in
2007. The increases include interim rates for GSWC's Regions II and
III service areas, totaling approximately $1,357,000 annualized. Due
to a delay in issuing decisions on the General Rate Cases for rate
increases in Region II and to cover general office expenses at the
corporate headquarters, the Administrative Law Judge of the CPUC
assigned to these cases issued an order for the interim rate
increases. By the CPUC statute, once the final rates are approved,
they will be made effective retroactive to the date the interim rates
are in effect.

    Additionally, the CPUC approved temporary surcharges in Region I
water service areas of GSWC to recover previously incurred supply
costs of approximately $2,019,000 recorded in the supply cost
memorandum accounts. Further, the CPUC approved a surcharge in GSWC's
Region III service area to recover approximately $744,000 of discounts
and costs incurred for the California Alternative Rates for Water
("CARW") Program, a program that benefits low-income customers of
GSWC. All surcharges are in effect January 1, 2007. Regulatory assets
have been previously established for the collection of these two
items.

    Certain matters discussed in this news release with regard to the
Company's expectations may be forward-looking statements that involve
risks and uncertainties. The assumptions and risk factors that could
cause actual results to differ materially, include those described in
the Company's Form 10-Q and Form 10-K filed with the Securities and
Exchange Commission.
