"If you menaged to accomplish both your Primary and Secondary Objectives, you have been very good at your job, as such, if I feel like, of course, you will be assigned a Reward in the form of Credits. The number written here is simply how much EACH of the team members gets for his performance and once the Secondary Objectives is fullfilled, EVERYONE gets the same amount no matter if there was a specific person accomplishing the feat or if someone was sleeping by that time. Remember, however, that you will get this Reward only if the mission is Succesful, so, you won't get any bonus credit if, although your secondary objective was fullfilled, you failed in the Primary Goal thereby failing the whole mission."
