Uncertainty can prove costly when it comes to purchasing property insurance. When pricing catastrophe risks, underwriters must be able to quantify them accurately. Where uncertainties arise, underwriters often adjust prices in an attempt to compensate for the unknown or decline the risk entirely. Uncertainty also tends to drive up the loss estimates produced by CAT modeling tools used to help underwrite property coverage today. To avoid paying unnecessarily high prices, insureds should provide detailed data that creates a complete and accurate picture of their exposures in a schedule of values. Complete submissions based on more precise data are likely to receive a warmer welcome from underwriters who have seen an increase in submission volume in the current market. Brokers that can provide a detailed catastrophe risk assessment report using the latest modeling technology can help clients make more informed decisions about risk transfer strategies and better position them to achieve the most cost-effective insurance program.
