(The Hollywood Reporter) -- Activision said in a regulatory filing Sept. 8 that Kathy Vrabeck has resigned as president of the company's publishing division.

No reason was given in the company's filing with the U.S. Securities and Exchange Commission, and Activision did not return calls Sept. 8.

Vrabeck will continue as an employee in an unspecified role until April 1 when her contract expires, the company said.

Vrabeck was named to the post less than two years ago, though reportedly was passed over for a promotion in June when Activision tapped longtime Procter & Gamble executive Michel Griffith for CEO of the publishing division after Ron Doornik was promoted to chairman of the division.

In its filing, Activision said Vrabeck's resignation was effective Sept. 2 but that she'll stay on in an unspecified role until her contract expires.

The company said it has canceled some of her unvested options but that it will continue to pay her base salary and benefits and she'll accrue vacation days until her contract ends. Activision will also prorate her annual bonus for next year.

Vrabeck earned a base salary of $500,000 in fiscal 2005, received a $423,750 bonus and held more than 1 million options as of March 2005. Last fiscal year, she exercised more than 400,000 options for about $5.3 million.
