Yes he did. He said "I've invested a lot of money into this club". When he was challenged on that he danced around the lingo of rent accrued, which he seemed unable to comprehend as a liability on the club's balance sheet, and as point out, the point he hasn't asked for payment of said rent is because it's entirely ludicrous. He asset stripped the club, for property the club never paid rent on for 40+ years, then hey presto, no assets and a 400k+ annual charge ad infinitum.
The club was massively in debt when he took it on. There were no "net assets" just "net liabilities" to begin with. The ground was owned by the bank. No assets to strip.
He has since provided funds over the years and not collected rent. He has mostly provided funding, as far as I can see, by leveraging assets in his various companies by taking charges against said assets or on occasion no doubt selling those said assets (land typically but probably not always I guess).
Given your forensic accountancy skills you may also have noticed that instruments appear to have been set up a while back that would *appear* to allow the development company to provide funds against similar charges (I'm guessing primary assets envisaged being the land at Fossets and RH that now has significant value through planning permission. How that would, or indeed could, work is unclear, or indeed when. This might play into statements some may remember about the development allowing "recapitalisation" of the club or maybe not..)
I can only assume that you don't count funds from group companies owned by Ron, private limited companies with him as primary or main shareholder, as him really putting money in? Well if so then there is nothing to say other than quite possibly many will disagree.
In terms of "personal" non company cash injections he has reportedly remortgaged his house, and again this has been covered previously. But, to be honest, I'm sure that was in extremis as, as lovely as his house probably is (I have never driven past), what re mortgaging it would raise would be relatively insignificant against the sums here more widely.
So he has put a lot of money/investment in. And the plan will be to get it and more back through the developments at RH and Fossets. So when its all done no need to feel sorry for him. Very few will.
Yes the debts are bigger, and the money/investment put in, higher than it would have been if the club had been run properly/better. Again, don't feel sorry for him - in the end this started, many would argue, as a business transition with the purchase of the club, and hopefully ends when the club is sold to a buyer we want with a shiny new stadium and training facilities. (If along the way he has come to genuinely care for the club then that's another debate and let's not cloud this issue with that. BTW I'm not saying he has but I mention as an aside).
In the nicest possible way, and I know your questioning and desire to get to the facts is well meant, please don't come to me looking for a job in finance or as a commercial analyst...:-)
PS. I add for clarity, and as I have repeatedly said, Ron Martin has made many mistakes and will, no doubt, make many more. Regrettably..
