IBM sued for $2.5 billion

Mexico-based Iusacell SA de CV accuses IBM of making fraudulent representations that caused it to lose $2.5 bn in profits

Mexican mobile phone operator Iusacell SA de CV sued IBM Corp on Wednesday, accusing the US technology giant of making fraudulent representations that caused it to lose $2.5 billion in profits.

The lawsuit, filed in New York, was heavily redacted, leaving many of the claims unclear. But the complaint centered on a contract that Iusacell said IBM induced it to enter into Mexico.

"Events subsequent to the execution of the agreement have revealed that IBM both knowingly misrepresented and wrongfully concealed from Iusacell material facts both before and during the parties' relationship," Iusacell said in the complaint.

Iusacell is co-owned by television and retail mogul Ricardo Salinas' Grupo Salinas and broadcast and pay TV giant Grupo Televisa

A spokesman for Grupo Salinas had no immediate comment. IBM representatives and a lawyer for Iusacell did not immediately respond to requests for comment.

According to the lawsuit, Iusacell's management designed a plan in 2010 to increase the market share and revenue of the company, which was then the third-largest mobile phone operator in Mexico.

Doubtful its existing information technology systems could support the plan, Iusacell sought advice from IBM, the lawsuit said. Several pages of the complaint are then redacted, leaving it unclear what happened next.
