Reinsurance

Our reinsurance recoverable at December 31, 2012 relates to 85 companies. Thirteen major companies account for approximately 92 percent of our reinsurance recoverable at December 31, 2012, and are all companies rated A or better by A.M. Best Company (AM Best) or are fully securitized by letters of credit or investment-grade fixed maturity securities held in trust. Approximately seven percent of our reinsurance recoverable relates to business reinsured either with companies rated A- or better by AM Best, with overseas entities with equivalent ratings or backed by letters of credit or trust agreements, or through reinsurance arrangements wherein we retain the assets in our general account. The remaining one percent of our reinsurance recoverable is held by companies either rated below A- by AM Best or not rated.
