Affiliated Computer Services ( ACS) is repricing a slew of incorrectly dated options to its top brass.Notable among the options grants that are being revised is one to its chairman, Darwin Deason. This is the first time ACS has acknowledged that Deason benefited from incorrectly dated options, The Wall Street Journal noted. ACS, whose CEO and CFO were forced out after an internal investigation found they had intentionally backdated options, disclosed the repricings in a filing late Friday with the Securities and Exchange Commission. The company wrapped up its investigation at the end of November. According to the filing, Deason received 600,000 options with an original grant date of July 23, 2002. But ACS is now adjusting the date on 360,000 of those options to July 26, 2002, reducing their potential value by $655,200. ACS' investigation failed to conclude that Deason¿s options, along with others dated July 23, had been dated with "hindsight." But the company said it was repricing them anyway because the board¿s compensation committee meeting in which the grants were authorized occurred later, on July 28. The filing also said that the investigation found "evidence, though inconclusive, supporting contemporaneous and informal selection of the July 23, 2002 grant date." ACS said it didn't reprice all of the options dated July 23, just the amount necessary to avoid adverse tax consequences for the people who received them. In addition to the options dated July 23, ACS repriced several other grants with other dates, including some that went to its current CEO, Lynn Blodgett, who was promoted from COO after former CEO Mark King left in November. Also Friday, ACS confirmed its previous statement that it would incur a noncash expense of $51 million related to the repricings. ACS shares lost 19 cents to finish Friday at $48.95.
