The Federal Trade Commission has opened an antitrust investigation into Google Inc.'s proposed $3.1 billion purchase of ad-management technology company DoubleClick Inc.

　　Don Harrison， the senior corporate counsel for Google， said in a statement Monday that the acquisition “poses no risk to competition and should be approved.”

　　美國聯邦貿易委員會已經就谷歌收購DoubleClick的交易展開了反壟斷調查。此前谷歌宣布將以31億美元的價格收購網絡廣告公司DoubleClick。

　　谷歌高級企業法律顧問多恩·哈里森周一表示：“這一交易不會給競爭帶來任何威脅，我們有信心它將通過審查。”
