In the latest accounts filed the club recorded a loss of £570,370 compared to the previous year of £1,677,262. Charlie Goode was sold for circa £1 million during that period if I am not mistaken. From where I’m sitting to make the business viable on that basis you need to to either shave £1.6 million per year to break even, address any short fall in player sales, increase gate receipts or a combination of all 3. That would be a considerable challenge. Especially since a number of the support base consider the current spending to be inadequate, arguably massively so.
The Charlie Goode sale was not included in that year...... Accounts to year end 30th June 2020....Goode was sold on 19th August 2020. That money will appear in the 2021 accounts. Also set to appear in the 2021 accounts will be the PL grant to EFL clubs (375k minimum plus lost gate revenue share)
What did appear in those accounts for 2020 though was the money (gate and prize and TV revenue) banked from the FA Cup run, which I assume is the sum shown as "other operating income" on page 9, the sum of £483,845 which reduced the operating loss from just under £1.1m to the £570k figure you have already mentioned.
Also shown on page 13 are the player registration costs and income, which I take to be purchases of £114k (the Goode PURCHASE) and sales of £105k (Pierre and Morais), those being the undisclosed transfer dealings in that accounting period.
