A form of joint property ownership in which the owners may have unequal shares and which does not involve a right of survivorship.

Insurance covering loss due to acts of terrorism. Unless endorsed to exclude loss due to terrorism, commercial insurance policies issued in the United States (for example, commercial property policies, commercial general liability (CGL) policies, and commercial auto policies) generally provide terrorism insurance coverage. Terrorism insurance also may be written on a stand-alone terrorism policy.

Federal legislation enacted in 2002 to guarantee the availability of insurance coverage against acts of international terrorism. Under the Act, commercial insurers are required to offer insurance coverage against such terrorist incidents and are reimbursed by the federal government for paid claims subject to deductible and retention amounts. This legislation was modified and extended by the Terrorism Risk Insurance Extension Act (TRIEA) in 2005.

Passed in January 2015, after a delay when the outgoing Congress failed to reauthorize the Terrorism Risk Insurance Act (TRIA) in the last days of the 2014 legislative session, TRIPRA of 2015 extended TRIA through December 31, 2020. It also made several changes to the reinsurance program, including reducing the federal share of insured terrorism losses incrementally through 2020, increasing the trigger threshold for federal involvement in insured terrorism losses incrementally through 2020, and increasing the mandatory recoupment of federal losses incrementally through 2020.
