A measure of the capital required to absorb any unexpected losses that result from the risks an organisation assumes in regard to its business and operational activities. In insurance RBC management means an insurer calculates the capital needed to support different classes of business. Overall RBC is expressed as a ratio, the total capital of the company divided by the company’s RBC as determined by formulae. The FSA has proposed that insurers will be required to hold the higher amount of minimum capital requirement as set out in the EC Directives and enhanced capital requirement, a more risk sensitive calculation specified by the FSA.
