Golden State Water Company ("GSWC") subsidiary to impose temporary surcharges in
their Region III water service area to recover an under-collection of $2.9
million recorded in the supply cost memorandum account between November 2001 and
December 2003. The surcharges will go into effect on October 11, 2005 and are
expected to recover the $2.9 million over a twelve month period. This will
result in an increase to pre-tax income of $2.9 million in the fourth quarter of
2005.
