Credit Agricole said it took a 708 million euro ($950 million) hit related to its stake in troubled Banco Espirito Santo (BES) that nearly wiped out the third-biggest French listed bank's second-quarter net profit.

Portuguese bank BES, in which Credit Agricole has been a key shareholder since the early 1990s, posted a 3.6 billion euro first-half loss last week and unveiled higher-than-expected provisions to cover exposure to companies owned by its founding Espirito Santo family.
