Check F4 first : quarter after the quarter the company has given gifts of 30K shares quarterly: Quarterly Stock compensation awarded to directors pursuant to Plug Power's 2011 Non-Employee Directors Compensation Plan. http://yahoo.brand.edgar-online.com/displayfilinginfo.aspx?FilingID=10973163-995-8710&type=sect&TabIndex=2&companyid=11641&ppu=%252fdefault.aspx%253fcompanyid%253d11641 Awarded for what - $10M quarter lost by burning $20M cash ????
