The U.S. Treasury Department's Federal Insurance Office issued its first public report on Wednesday, Business Insurance reported. The 53-page "Annual Report of the Insurance Industry," provides a broad overview of both the life/health and property/casualty segments of the insurance market. The report is the first of several long-overdue public reports mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act. A more significant report detailing recommendations to modernize and improve insurance regulation in the United States is still forthcoming. According to the report, the prospect of continued low interest rates "poses a challenge to insurers seeking to balance investment risks and returns, especially while trying to build capital and to expand product offerings." However, after three years of declines, property/casualty insurers' net written premiums nearly returned to pre-crisis levels by 2011 and continued to grow in 2012, the report noted.
