Shell Oil Products U.S. and Motiva Enterprises LLC reached agreement with the attorneys general of 46 states and the District of Columbia to amend their policies to prevent underage tobacco sales, Bloomberg reported Oct. 8

The new measures will include employee training on underage smoking health risks, conducting compliance checks, and adopting policies requiring employees to notify the parent company when sales to minors occur.

Shell, owned by Netherlands-based Royal Dutch Shell Plc, and Motiva, owned by Saudi Refining Inc. and Shell Oil Co. (another unit of Royal Dutch Shell), inked the agreement, which did not include the states of Indiana, North Carolina, North Dakota and Wisconsin.

Other companies have entered into similar agreements with the states, including Exxon Mobil Corp., ConocoPhillips, 7-Eleven Inc. and Walgreen Co.
