American Apparel's board believes a bid by Irving Place Capital to buy the retailer for up to $1.40 per share is far too low, and any takeover offer should be "several multiples" higher, a source familiar with the board's thinking said.

** Casino and entertainment company Caesars Entertainment Corp, whose largest operating unit plans to file for bankruptcy, said it would buy affiliate Caesars Acquisition Co in an all-stock deal.

** The ambitions of Kremlin-controlled oil champion NK Rosneft OAO to boost its global reach have been reined in by U.S. authorities, which torpedoed its acquisition of a Morgan Stanley oil trading business.
