The effectiveness of risk disclosure practices in the European insurance industry

This paper aims to examine whether risk disclosure practices affect stock return volatility and company value in the European insurance industry.

Using a self-constructed “risk disclosure index for insurers” (RDII) to measure the extent of information disclosed on risks and using panel data regression on a sample of European insurers for 2005-2010, it tests the relationship between RDII and stock return volatility; whether this relationship is affected by financial crisis; and whether RDII affects insurance companies’ embedded value.

The main results indicate that higher RDII contributes to higher volatility, suggesting that “less is more” rather than “more is good”. However, higher RDII leads to lower volatility when the insurer has a positive net income, thus “more is good when all is good” and “less is good when all is bad”. Furthermore, the relationship between RDII and stock return volatility is not affected by financial crisis, raising concerns regarding the effectiveness of insurers’ risk disclosure to reassure the market. Moreover, higher RDII is found to impact positively on embedded value, thus contributing toward higher firm value.

The findings could drive insurers’ choices on communication and transparency, alongside regulators’ decisions about market discipline. They also suggest that risk disclosure could be used to strengthen market discipline and should be added to the other variables traditionally used in stock return volatility and firm value estimation models in the insurance industry.

This paper offers new insights in the debate on the bright and dark sides of risk disclosure in the insurance industry and provides interesting implications for insurers and their stakeholders.
