More than 419,000 properties are now covered by the FAIR plan, which is one of the state's primary insurers.

A faster rating approval process is among the reforms being sought.

Allstate is the first major insurer to hint at resuming business in the state.

The decision will affect 12,556 policies with premiums of $11.3 million.

The California FAIR Plan faces $311 billion in potential losses, up from $50 billion six years ago.
