In the Q&A last night, Charlie commented that the club is fairing relatively well in the current circumstances, and a lot better than most other clubs - primarily because of a low cost base. They've been able to take advantage of the government support schemes which saw most employees placed on Furlough. There is a concern about starting the season with no guarantees fans won't be locked out at some point depending on external circumstances - because there's no assurances support will be forthcoming and the expectation is seemingly for owners to meet running costs.
Don't forget, the club makes more money from being in the football league than it does from gate receipts... Hence the importance of being an EFL member club. Presumably the club didn't have to return any of this membership money last season (despite not completing a full season), and has received some or all of funds for the season ahead.
I'm pretty sure Charlie said if not for COVID-19 the club would have made a profit last season, rather than a small manageable loss. Of so that's a big turnaround from reported annual losses of £250-500k a year for the last 10-15 years.
Make sure you attend the next meeting Neil, I think you'd get a lot of information out of them by hearing things first hand. It'd help add some basis to some of speculation
