The highest level of DM-4 in 2012 was $319,900, plus a potential 39% maximum performance bonus of $124,761. But if DM-4 and everything below it is excluded, that will raise the bar to essentially $320,000. So the only classifications that would apply would be GCQ-10, which I believe are traditional appointments, and CEO-6, 7, and 8.
