As used herein, 1) “we” means the insurer listed on the Declarations or the Certificate of Insurance, as applicable; and 2) “you” means the first person or entity named on the Declarations or the Certificate of Insurance, as applicable.

You are hereby notified that under the Terrorism Risk Insurance Act, as extended and reauthorized (“Act”), you have a right to purchase insurance coverage of losses arising out of acts of terrorism, as defined in Section 102(1) of the Act, subject to all applicable Policy provisions. The Terrorism Risk Insurance Act established a federal program within the Department of the Treasury, under which the federal government shares, with the insurance industry, the risk of loss from future terrorist attacks.

This Notice is designed to alert you to coverage restrictions and to certain terrorism provisions in the Policy. If there is any conflict between this Notice and the Policy (including its endorsements), the provisions of the Policy (including its endorsements) apply.

The Act applies when the Secretary of the Treasury certifies that an event meets the definition of an act of terrorism. Originally, the Act provided that to be certified, an act of terrorism must cause losses of at least five million dollars and must have been committed by an individual or individuals acting on behalf of any foreign person or foreign interest to coerce the government or population of the United States. However, the 2007 re-authorization of the Act removed the requirement that the act of terrorism must be committed by or on behalf of a foreign interest, and now certified acts of terrorism may encompass, for example, a terrorist act committed against the United States government by a United States citizen, when the act is determined by the federal government to be “a certified act of terrorism.”

In accordance with the Act, we are required to offer you the ability to purchase coverage for losses resulting from an act of terrorism that is certified under the federal program. The other provisions of this Policy, including nuclear, war or military action exclusions, will still apply to such an act.

The Department of the Treasury will pay a share of terrorism losses insured under the federal program. In 2015, the federal share equals 85% of that portion of the amount of such insured losses that exceeds the applicable insurer retention and shall decrease by 1 percentage point per calendar year until equal to 80%.

If aggregate insured losses attributable to terrorist acts certified under the Terrorism Risk Insurance Act exceed $100 billion in a calendar year (January 1 through December 31), the Treasury shall not make any payment for any portion of the amount of such losses that exceeds $100 billion.

Further, this coverage is subject to a limit on our liability pursuant to the federal law where, if aggregate insured losses attributable to terrorist acts certified under the Act exceed $100 billion in a calendar year (January 1 through December 31) and we have met our insurer deductible under the Act, we shall not be liable for the payment of any portion of the amount of such losses that exceeds $100 billion. In such case, insured losses up to that amount are subject to pro rata allocation in accordance with procedures established by the Secretary of the Treasury.

In accordance with the Act, we offered you coverage for losses resulting from an act of terrorism that is certified under the federal program. This notice confirms that you have chosen to accept our offer of

coverage for certified acts of terrorism. The Policy’s other provisions, including nuclear, war or military action exclusions, will still apply to such an act. The premium charge for terrorism coverage, if any, is shown separately on the Declarations or the Certificate of Insurance, as applicable.

Payment of any Insured Loss under this Policy shall only be made in full compliance with all United States of America economic or trade sanction laws or regulations, including, but not limited to, sanctions, laws and regulations administered and enforced by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”).
