Google let the cat out of the bag on March 2 when the company accidentally posted internal information to its investor relations website, the company confirmed in a U.S. Securities and Exchange Commission (SEC) filing Tuesday.Among the statements not intended for publication were: "Our ads business for the moment is healthy and growing and we\u2019re on a strong trajectory ... projected to grow from US$6 billion this year to $9.5 billion next year based purely on trends in traffic and monetization growth," the filing said. However, the company couched that optimistic forecast with a word of caution by adding "strong competitors are attempting to aggregate traffic ... AdSense margins will be squeezed in 2006 and beyond," it said. "These notes were not created for financial planning purposes, and should not be regarded as financial guidance," Google said in the filing. The company does not normally provide financial guidance regarding earnings and profits.The SEC filing confirmed the accuracy of estimates made in the forecast regarding employee stock options. "The statement regarding the stock-based compensation charge of $342 million, which relates to stock awards granted to employees and directors prior to 2006, is a materially accurate reflection of Google\u2019s current expectations."The flap was the second in the same number of weeks for Google. On Feb. 28, investors sent the company\u2019s stock spiraling after Google Chief Financial Officer (CFO) George Reyes told a Merrill Lynch & Co. conference that its advertising revenue growth would inevitably slow. "Our revenue growth rate has generally declined over time and we expect that it will continue to do so as a result of the difficulty of maintaining growth rates on a percentage basis as our revenues increase to higher levels," Google said in a statement released February 28.-Steven Schwankert, IDG News ServiceFor related coverage, read Google Plans \u2018Total Storage,\u2019 Google Shifts Search Records Out of China and CFO Comments Drop Google Stock.Keep checking in at our CIO News Alerts page for updated news coverage.
