In 2004 alone, 57 percent of more than 500 companies have purchased some form of terrorism insurance. In 2003, that figure hovered at about 24 percent. Aon?s survey, ?Terrorism Risk Management & Risk Transfer Market Overview,? was released in mid-December 2004. (It can be obtained after registering with Aon.) Industry experts have concluded similarly. According to the Insurance Information Institute in November 2004, terrorism insurance policies had nearly doubled to 46.3 percent in the second quarter of 2004, up from about 20 percent during the same period in 2003.

One reason for the up-tick is that terrorism risk insurance has become both more affordable and more available to industry. When TRIA was first released, the pricing schedule was confusing and unimportant. Organizations of high profile?namely, those in targeted cities and with universally recognized US institutions–have increasingly taken out policies. However, the capacity for the insurance industry to offer terrorism insurance fell short of the market need.
