New rules went into effect on February 13, 2020, that implemented the Foreign Investment
Risk Review Modernization Act of 2018 (FIRRMA), expanding the authority of the Committee
on Foreign Investment in the United States (CFIUS), the US agency that reviews foreign
investments in the US for potential national security concerns.
The new rules include CFIUS authority over certain transactions that involve property rights in airports or maritime ports. This
publication summarizes these new authorities relating to airports and maritime ports and provides insight into how investors
and operators impacted by these authorities can account for CFIUS regulatory risks going forward.
