WASHINGTON—State Farm Mutual Insurance Company was the largest property and casualty insurer in 2013, according to data contained in the 2014 report of the Federal Insurance Office, with a 10.29 percent market share of all personal lines and commercial PC insurers based on premiums written.

The report said U.S. insurers in general “continue to show resilience in the aftermath of the financial crisis.”

The report said PC insurance sector premiums have “grown consistently” since 2010, and reached a record high of $71 billion on a net earned basis in 2013. The PC sector’s combined ratio for 2013 dropped below 100 percent for the first time since 2007, which was largely attributable to a reduction in catastrophe losses.
