— The U.S. Senate, which had been deadlocked on the issue of a federal role in terrorism insurance, might be on the verge of reaching a consensus.

The elements of a Senate bill appear to be the following:

• First, insurers would be required to retain 7.5 percent of net direct written premium for any terrorism loss.

• Second, for losses below $10 billion, insurers would pay 20 percent of all terrorism-related claims, while the federal government would pay 80 percent.

• Third, for losses above $10 billion, insurers would pay 10 percent while the federal government would pay 90 percent. This would be a direct quota-share program with no requirement that insurers repay the government for its share of the losses.
