An impending tax ruling threatened to unravel a $3-billion deal in which Marathon Oil Corp. would consolidate ownership in Marathon Ashland Petroleum by buying Ashland Inc.'s interest.
Ashland, which owns 38% of the gasoline refiner and marketer, said it feared that the ruling from the Internal Revenue Service could leave it with an unknown amount of tax liability for gains from the transaction.
Ashland shares fell $1.03 a share to $56.67, and Houston-based Marathon fell 21 cents to $37.11, both on the New York Stock Exchange.
