There isn't any filing fee for 10-Q's--the cost of producing the 10-Q depends on PTOI's internal costs. My guess is that CFO Mr. Banerjea just takes the previous 10-Q and changes the numbers...which probably takes him about a day.
What happened to that $100k loaned to PTOI is anyone's guess. In my opinion, though, that should be the very least of investors' questions. Investors don't even know if the flagship which was supposedly running for about six months in 2013 produced any results which would indicate it's worthwhile to use in any capacity.
