Despite its major success, Groupon restated its Q4 earnings back in March 2012 after a higher-than-expected number of customers demanded refunds on orders they were apparently not happy with.
According to the company, the launch of new, higher priced products late last year led to a considerably higher return rate than the company was used to.
A report, which elaborated on the restatement, explained that when customers demand refunds within 60 days, Groupon's accounting treats the refund as a "contra-revenue" event, meaning that it reduces Groupon's revenue earning. After 60 days, refunds are treated as an expense, so they only hit earnings.

Groupon currently employs 10,000 men and women and in 2010 was valued at $1.35 billion.
