Google Inc. blamed R.R. Donnelly & Sons Co., a company that handles financial printing, for the premature release of its third-quarter results earlier Thursday.

"RR Donnelley, the financial printer, informed us that they had filed our draft 8K earnings statement without authorization," Mountain View, California-based Google said in a blog statement.

Google ceased trading of its shares while it makes final touches to the document. The company's stock plunged after the publication of the release, which showed profit and sales that fell short of analysts' projections. Its incompleteness was evidenced by the inclusion of the phrase, "PENDING LARRY QUOTE," just above a summary of results.

R.R. Donnelly fell as much as 6.5 percent to $10.14, the lowest price since May 23, after Google's statement was released. Shares of the Chicago-based company had declined 25 percent this year through yesterday.
