Groupon filed for a $750 million IPO in June 2011, but in August of last year the company was forced to discard its "adjusted consolidated segment operating income" accounting method which inflated the value of the company by not counting customer acquisition, online marketing, or stock-based compensation. Then, in September, it had to revise its 2010 results because of an accounting error that counted fees paid to merchants as revenue. Groupon said they made $713.4 million in revenue for 2010, while the SEC found the number to be $312.9 million. Groupon was eventually forced to revise the number.
