I would assume that if money is lent, then money is owed.  So yes.  Instead of demanding payment immediately, it appears an arrangement was made for payment from future revenues up to a 20 year period.  So an expectation of both production and revenue is implied.  Some of the money owed appears to be loans, and others appear to be for services rendered.  At least, this is how I am reading the filing.
