RBC (Risk-Based Capital)
Risk-Based Capital (RBC) is the NAIC's statutory solvency framework that determines how much capital an insurer must hold, scaled to the types and levels of risk in its business—triggering regulatory intervention when capital falls too low.

Definition
Risk-Based Capital (RBC) is a regulatory framework developed by the National Association of Insurance Commissioners (NAIC) that establishes minimum capital and surplus requirements for insurance companies based on their specific risk profiles, rather than applying a flat dollar minimum. RBC formulas account for four primary risk categories: asset risk (investment portfolio quality and concentration), credit risk (reinsurance recoverables and receivables), underwriting risk (adequacy of reserves and premium pricing), and off-balance-sheet risk (exposure from affiliated transactions). The formula produces an Authorized Control Level (ACL) RBC figure; each insurer's actual capital (Total Adjusted Capital, or TAC) is then compared to this benchmark. Ratios below 200% of ACL trigger Company Action Level intervention (the insurer must file a remediation plan); below 150% triggers Regulatory Action Level (the regulator takes direct oversight); below 100% triggers Authorized Control Level (the regulator may seize the company); and below 70% triggers Mandatory Control Level (the regulator must seize the company). The RBC system replaced flat minimum capital requirements in 1994 after multiple high-profile insolvencies in the late 1980s and early 1990s revealed that fixed minimums were inadequate. Each year, approximately 20–40 insurers trigger Company Action Level or higher RBC thresholds, though most resolve the issue through capital infusions or run-off without insolvency.
