Blackrock to do US sums

The US National Association of Insurance Commissioners (NAIC) has contracted Blackrock Solutions to help state regulators calculate risk-based capital (RBC) requirements for the commercial mortgage-backed securities (CMBS) held by insurers.

Blackrock will look at more than 7,000 CMBS holdings by US insurance companies at the end of 2010 to help regulators work out each insurer’s solvency requirements.

There were 16 bidders for the contract.
