Report Weighted Guidelines Method History in Contract Pricing Including CAS & Allowable Costs Posted January 26 1 hour ago, Vern Edwards said: I thought we were talking about the weighted guidelines. The fee limitation on non-R&D CPFF is 10 percent, not 15 percent, of estimated cost, and it is statutory per 10 USC 2306(d) and 41 USC 3905. So are we talking about WGL or statute? Typo. Should have said: What if we all focused on one piece of the puzzle: Why does a limitation of 10% apply to non-R&D CPFF? Why not 17.5%? Or 4.6%? Where did the 10% come from? OP talked about the "original ranges" - this conversation is about statute, but not in a vacuum. WGL is a very widely-utilized tool with a foundation in statute.
