AIG Advisor Group is partnering with Castle Rock Innovations Inc. to upgrade the accounting and regulation compliance it needs for its retirement plan sponsors, AIG announced Tuesday.

AIG will use the AXIS Retirement Analytics Platform provided by Castle Rock, a Chicago-based provider of technology for the financial industry. AXIS supports account identification, data aggregation, automated disclosure and benchmarking in a single web-based solution.

The platform is designed to enable AIG to comply with 408(b)(2) regulations that require retirement plan service providers to fully disclose their retirement plan fees, compensation and services provided to plan fiduciaries, AIG says.
