Dubai Ports World says it will take months to sell its holdings in the United States, and these assets are worth "hundreds of millions" of dollars.

DP World was in the middle of a recent political storm in the U.S. after the company, based in the United Arab Emirates, purchased facilities in ports around the world, including some U.S. container and passenger terminals.

Members of the U.S. Congress and others expressed concern that DP World would not do enough to protect U.S. ports from terror attack.

DP World said last week that it would "transfer" its U.S. holdings to a U.S. entity, but gave few details.
