National benchmark indexes retreated in 12 of the 18 western-European markets. The U.K.'s FTSE 100 Index slipped 0.1 percent, Germany's DAX Index added 0.1 percent, while France's CAC 40 lost 0.1 percent.

Vivendi SA dropped 2.7 percent to 15.30 euros after Activision Blizzard Inc. (ATVI) was said to have shelved a plan to buy back shares held by its French parent amid a disagreement on price. The world's largest video-game publisher planned to buy at least part of Vivendi's stake as recently as last month, people with knowledge of the talks said. Vivendi, which has a 61 percent Activision holding valued at more than $10 billion, is still exploring how to extract cash from its stake, including a possible dividend recapitalization, one of the people said.

3i Group Plc lost 4.8 percent to 345.8 pence after the U.K.'s largest publicly traded private-equity firm reported a net value of its assets of 311 pence a share for the full year.
