Groupon updates IPO filing, admits it's unprofitable
When Groupon filed in early June to go public, the daily deals company drew a barrage of criticism for its reliance on an unorthodox accounting practice that masked some of its losses. Bowing to the critics, Groupon amended its IPO filing on Wednesday to strip out the odd metric.

Groupon's initial IPO filing highlighted a nonstandard metric called "adjusted consolidated segment operating income." The unwieldy "ACSOI" stripped out Groupon's steep costs for marketing and acquiring new subscribers -- and it made a big difference in the numbers.

In Groupon's original filing, its ACSOI accounting showed operating income of $60.6 million for all of 2010 and $81.6 million for the first quarter of 2011.

Numbers in an updated filing Wednesday, which removed ACSOI and instead used only standard accounting procedures, were quite different. On that basis, Groupon incurred a $420 million operating loss for 2010 and a $117.1 million loss in the first quarter.
