According to the Post, Los Angeles-based buyout firm Leonard Green & Partners (which revealed it had a 9.5 percent stake in the company in July) is interested in pursuing a takeover bid if an auction doesn’t commence in the coming weeks.

A source told the paper, if it gets to mid-January and a sale has not started, there may be difficult conversations,
