RR Donnelley blamed as premature Google filing wipes $20bn off shares:
The incomplete results statement revealed a 20% slide in Google's quarterly profits to $2.2bn (£1.4bn), missing analysts' estimates and sparking a flurry of trading that wiped nearly $20bn off the company's market value before trading was suspended.
Google placed the blame firmly on RR Donnelley in a statement released shortly after the blunder. It said: "Earlier this morning RR Donnelley, the financial printer, informed us that they had filed our draft 8K earnings statement without authorization.
Tom Quinlan, chief executive of RR Donnelley told the Wall Street Journal that "human error" was responsible for the early SEC filing, which he added was "not common in our world".
RR Donnelley, which files more than 100,000 documents each year, said in a statement that it would be investigating the situation.
