| Abstract: | The International Accounting Standards Board (IASB) started a project on Insurance Accounting to apply the principles of fair value to insurance businesses. The so called ?asset and liability approach“ would focus on the balance sheet, with both assets and liabilities being reported at fair values, while income and expenses are defined in terms of changes in the values of those assets and liabilities. Indeed, there are no deep and liquid markets for insurance liabilities. Thus, the fair value has to be calculated as a theoretical value, using assumptions concerning future events, risk provisions and discount rates. Both in theory and in practice a generally accepted modelling of fair value is missing. Particularly with regard to the deviation of a Market Value Margin (MVM), which reflects the premium that a marketplace participant would demand for bearing the uncertainty inherent in the cash flows, there is a need for adequate modelling. Transforming the CAPM for determining risk loads in insurance will mean measuring the correlation between insurance companies’ returns from underwriting and market returns on its shareholders’ equity. The criticism on an underwriting beta focuses on (a) the basic assumptions of the CAPM, (b) the absence of active markets for insurance liabilities and (c) the unreliability of estimating underwriting betas. |
