I don't want to get embroiled in suggesting what people have / have not taken but the recently published accounts show a very sizeable chunk of money being paid to Dr Pleming and his company in fees, salaries and expenses (£130,000 of which £91,760 in expenses, must be a lot of receipts).
They operated at a cash surplus for two years whilst writing off a vast sum against expenses / depreciation on the trading subsidiary which isn't explained so can't say whether its fair or reasonable or not.
There are clearly lots of things that are well within what you'd expect in any company which is absolutely fine, however, a few stand out as needing an explanation.
