Standard & Poor's placed on CreditWatch with negative implications its triple-'B'-plus long-term corporate credit rating on Coflexip S.A., the parent company of the Coflexip Stena Offshore group. The 'A-2' short-term corporate credit rating was affirmed, as the long-term rating will not fall below triple-'B' The rating action follows a previous announcement that Coflexip has entered into a conditional agreement to acquire the deepwater division of Norway-based Aker Maritime ASA in a cash and debt-financed transaction set to weaken the group's previously very strong balance sheet. The transaction, which aims to create the leading global provider of offshore solutions in the oil services industry, would cost $513 million, with an additional $112 million of net debt assumed.
