First of all, the government or the Treasury Board has to give the authority, if I understand it correctly. I'm not an expert in this area, so I have to qualify that.
It is not a bonus. You have to earn it. If the government authorizes the pay of a bonus or pay at risk to be paid to the public service—the EX categories—then we, the people in the organization, make a determination on who is to be paid, based on their performance, and what amount they will get. I make that final decision.
