Without look at this assets I probably should not say much but it is my guess it would be very difficult to give back even if he wanted to.
It says he collected 80 million over what may be a four year period depending on what months that use as start and end times for this information, it also states that they are worth 72 million. I would be surprised if 10% of those assets are in bank or short term fixed security assets but I really don't know. My guess is that most of this value is a combination of tangible and non-tangible assets. Some of the non-tangible assets could easily have their value based on what someone in finance would call the dividend discount model. It would not surprise me if they tried to liquidate in four weeks that it would only bring in half the worth, it also would not surprise me if it could only pull in 25%, maybe only 10%. I cannot know with out knowing all the assets but I would be shocked if they could produce 72 million.
