In accepting Kumar's decision, CA chairman Lewis Ranieri said, "The Board wishes Sanjay and his family well. The Board is committed to reaching a settlement of the government's investigation into the company's past accounting practices as quickly as possible. We are working hard to take the remedial steps necessary to put this entire matter behind CA. Sanjay's decision to leave CA was made in that spirit."

As previously reported, Kumar stepped down as CA's chairman and CEO in April and was replaced by interim CEO Ken Cron.

In explaining his decision to leave, Kumar said, "It has become increasingly clear to me in the past few days that my continued role at CA is not helping the company's efforts to move forward. I understood that my stepping down as chairman and CEO represented a break with the past, but I have reluctantly concluded that as long as I hold any position, focus on past issues and my current role will continue.

"While I am grateful for the support and encouragement I have received from customers, employees and shareholders, I believe my decision to leave at this time is the right one," Kumar continued. "It hopefully will permit CA to move forward."

As previously reported, the United States Attorney's Office and SEC investigations are continuing.
