The Travelers Companies TRV Terrorism Risk Insurance Program, terrorism-related losses triggering program coverage since program was established

billion aggregate during a program year, participating insurers will not be liable under the program for additional covered terrorism losses for that program year. There have been no terrorism-related losses that have triggered program coverage since the program was established. Given that the law establishing the program remains untested, there is substantial uncertainty as to how it will be applied if an act of terrorism is certified under the program. In addition, application of the program to a specific event will depend upon whether the government has designated such event as a covered event. It is also possible that future legislative action could change or eliminate the program. Further, given the unpredictable frequency and severity of terrorism losses, as well as the limited terrorism coverage in the Company’s own reinsurance program, future losses from acts of terrorism, particularly involving nuclear, biological, chemical or radiological events, could be material to the Company’s operating results, financial position and/or liquidity in future periods. In addition, the Company may not have sufficient resources to respond to claims arising from a high frequency of high severity natural catastrophes and/or of man-made catastrophic events involving conventional means. While the Company seeks to manage its exposure to man-made catastrophic events involving conventional means, the Company may not have sufficient resources to respond to claims arising out of one or more man-made catastrophic events involving cyber, nuclear, biological, chemical or radiological means.
