In a move that caught many of those in the real estate and insurance industries by surprise, the U.S. Senate adjourned Dec. 16 without a vote on a bill to extend the Terrorism Risk Insurance Act for six years. The program will now expire Dec. 31, and the negative repercussions for the real estate industry are expected to be significant.

The TRIA program has served as the backstop for insurance companies’ losses from acts of terrorism ever since it was ratified with widespread bipartisan support after the 9/11 terrorist attacks, which caused the private market for terrorism insurance to collapse.
