CE closes at EUR 9.26 on Thursday

I thought I would mention that ordinary shares of CE closed at a price higher than the acquisition price today in Amsterdam. With less than 2 hours of trading left, CE started to trade at a price of EUR 9.26, with even some transactions at EUR 9.27, which puzzles me. It seems unlikely that Staples is buying, because that would mean they would have to pay the higher price to all other shareholders who tender their shares. The only reason I can think of, is that there are some shorts that are forced to cover at the last minute, but that seems very irresponsible and strange. Maybe the last trading day will also show some interesting movements.
