Sandisw,
I guess it depends on how motivated you are to press the point, but this represents a change in policy. In the past the incentives were given with contracts that were broken up in smaller increments as long as the total met the requirement. If this is truly the policy now, you could ask for management exception. If it is your plan to break in down in the future you will be faced with the same dilema--maybe it would be best to get it sorted out now?
