California Insurance Commissioner Announces Intention to Approve 21st Century Insurance Company Rate Filing

21st Century Insurance Company announced that California Insurance Commissioner John Garamendi intends to approve a rate filing that will allow the Company to comply with the Commissioner’s recent regulatory changes. The rate filing is expected to be effective in late November 2006 and will create an average rate decrease for California policyholders of 5%.

“While 21st Century is actively expanding across the U.S., our roots are in California. We’ve been operating here for almost 50 years and have always complied with the state’s regulations,” said Chief Executive Officer & President Bruce Marlow. “Over the last two years, the California marketplace has been very stable. The Commissioner’s new regulations and the subsequent rate filings by all auto insurers operating in the state may increase consumer shopping behavior, which has historically benefited 21st,” added Marlow.

21st Century Insurance Group is the seventh largest writer of personal automobile insurance in California and employs more than 2,700 people, with more than 1,600 employees at its headquarters in Woodland Hills, California.
