IBM Corp. said Monday it signed a five-year agreement with French retailer Carrefour SA to improve and manage its information technology infrastructure for euro180 million, or $251.7 million.
IBM signed the contract with Carrefour _ the second largest international retailer after Wal-Mart Stores Inc. _ in June.
IBM said the agreement would allow the retailer to control costs and improve IT security, among other benefits.
Carrefour France's IT infrastructure will be hosted from IBM's first European green data center in Montpellier.
IBM shares lost 8 cents to $101.65 on Monday.
