Nope still “breaks my brain”, someone else wrote that this structure is because it would be just sitting in their bank account if they collected it all up front, its not different if its just in mine, unless its invested in liquid assets but if its in liquid assets then it could decline in value in which case I wouldnt have that much to invest. How do people really deal with this model? I wonder what GPs have seen from their LPs.
