Tan is not taking money out, but has stopped pumping money in.
The club has to make sure it can run within the FFP rules which mean a max average loss of £13m per season over a three season period - this in itself REQUIRES a capital injection of £8m per season under the rules or otherwise the cap is £5m. This is why Tan has already stated that there will be a debt to equity conversion of £8m per season for 5 seasons.
Under the FFP calculations the club made a loss of £10m in 2014/5 (although there was a disagreement with the EFL on the calculation), when we get the official figures for 2015/6 (which should be soon) we will then have an indication of the scale of the problem for the club for this season with the parachute payments falling.
