Consulting is just an expense line item. With all the new accounting rules, the auditors would advise MP if a statement of the line item is necessary. Consulting is a common practice as you well know and any public company could write a report it would take a week to read if they had to explain everything. Items like cost of sales usually is one of the larger expenses on an income statement and you hardly ever see any comments on that.
I would think that if there is a shareholders meeting, the question could or maybe should be asked. After all, the information has been disclosed and I see no reason why MP could not answer the question.
I would really like to know how MP is going to come up with the money to pay the new guy.
