The Department of the Treasury is issuing these proposed rules to implement changes to the Terrorism Risk Insurance Program (TRIP or Program) required by the Terrorism Risk Insurance Program Reauthorization Act of 2015. In addition, Treasury proposes for the first time a Civil Penalties rule under TRIP, pursuant to authority granted by Congress in the Terrorism Risk Insurance Act of 2002. Treasury proposes adoption, with certain minor changes, of a previously proposed rule addressing the Final Netting of Payments. Finally, certain other changes are proposed to various sections of the prior rules in order to clarify certain matters, make technical and conforming changes, and to address changes required by the passage of time and other legislation.
