California regulators signed off on a pair of rate increases requested by State Farm General Insurance Co. in December 2020, one of which may be the most impactful homeowners hikes approved by any state regulator during the month.

Subsidiaries of State Farm Mutual Automobile Insurance Co. obtained five rate increase approvals across four states, which could boost calculated premiums by $123.4 million.

Progressive Corp. received approval for a single rate reduction of 5.5% in Oregon that may decrease aggregate written premiums by about $800,000.
