"Put simply, I do not believe that Purdue Global has yet proven itself to be viable in the long term. It is running on IOUs and foregone payments to its OPM partner, Kaplan Higher Education. And it will be very difficult to get to the point of true profitability and financial viability as long as Purdue Global has to continue spending more than $4,400 per enrolled student just on marketing expense."
