IEnova, the Mexican unit of U.S.-based Sempra Energy, said on July 12 that it had restructured a deal to buy state-run oil company Pemex's 50% stake in pipeline company Gasoductos de Chihuahua for $1.108 billion.

In December, Mexico's Federal Economic Competition Commission (COFECE) said it objected to a previous incarnation of the deal, as Pemex had failed to sell its stakes in a LPG pipeline and a natural gas pipeline, as ordered by a previous antitrust agency.

On July 12, IEnova announced it had restructured the deal with Pemex, which would be able to proceed once it had finished complying with the commission's conditions.

IEnova said it would pay a minimum of $1.108 billion for the stake, less than the $1.325 billion it pledged to pay last July.
