Camico, a major liability insurance provider for CPA firms, said Thursday it had posted its fourth consecutive year of gains in 2013, earning net income of $1.2 million and a policyholders’ surplus of $38.5 million, up from $38.2 million in 2012.

The policyholder retention rate last year was 92.6 percent. Camico said it has consistently maintained a retention rate of more than 92 percent for the past 20 years.

“CAMICO is continuing to build long-term value for CPAs by providing unmatched expertise and solutions via a financially strong program,” said Camico chairman Robert P. Evans. “Our dedication to the accounting profession and outstanding service drive the high level of policyholder satisfaction seen year after year.”

The company’s results are detailed in its 2013 Operations Report, which has been posted online at www.camico.com along with 2013 audited financial statements from Ernst & Young.
