Calpine Adjusts Earnings Statements for Last Three Years

LCG, March 4, 2003San Jose-based Calpine Corporation restated its earnings results for 2000, 2001, and 2002 after changing accountants.

2000 earnings were lowered from $373 million to $369 million. 2001 earnings were lowered from $648 million to $623 million, and 2002 earnings were reduced from $142 million to $119 million.

Last March Calpine switched auditors, dismissing Arthur Andersen LLP for Deloitte & Touche LLP.
