According to Yahoo Finance, Autodesk officer George Bado was made $0.4 billion richer through the sale of ADSK shares at $17525 per share. No doubt that the decimal place got left out, and the share price should have been reported as $17.525.
Even though they really aren't making hundreds of millions in a single stock sale, Autodesk executives are not suffering financially. As reported by Yahoo Finance for the one-month period of April 21 - May 19, the estimated proceeds from option exercises and automatic sales were:
$0.79 million -- CASTINO ALFRED
$1.48 million -- BADO GEORGE M
$2.87 million -- BASS CARL
$6.59 million -- BARTZ CAROL
