Yeah, y/e 2012 over y/e 2011, AR grew 51% on a 28% increase in sales. So there's 10, 11 M in sales that look a little funky. And the real world factor could be higher if people in the channel actually paid for stuff they're going to return.
FYI, from the conference call:
Accounts receivable increased to $76.3 million compared with $50.6 million a year ago due to higher fourth quarter revenue in 2012 and sales materializing later in the quarter. Included in this increase is $13.7 million of incremental receivables due to the launch of Astro products at retail in the fourth quarter. Additionally, the company entered into a multi-buyer credit insurance program in Q4 to help mitigate and manage the risks associated with our worldwide receivable portfolio going forward."
