The Seventh Circuit noted that while the employee claimed that he was entitled to a larger commission under terms of 2005 incentive plan, record showed that employee did not close deal with client until March 2006. Furthermore, the 2005 plan had a December 25, 2005 deadline in order to qualify for commission under 2005 incentive plan. Thus, the Seventh Circuit rejected the employee's contention that 2005 plan remained effective until sometime in 2006 when 2006 plan became effective.
