Japan's Toshiba Corp warned it was likely to mark down its reported operating profit for the three fiscal years through March 2014 by a total of at least 50 billion yen ($419.43 million) after an investigation into accounting irregularities.The announcement late on Wednesday soothed investors' fears the probe could lead to a major scandal, and helped push up Toshiba's American Depositary Receipts (ADRs) 12 percent overnight. Toshiba had delayed its quarterly earnings announcement and canceled a year-end dividend due to the probe, launched last month and extended last week.  (Reporting by Ritsuko Ando)
