I'm getting the figures from the filed accounts. I can't post them here so go to cro.ie and do a search on company number 245954.
A word of caution regarding newspaper articles and the likes: in a lot of cases the journalists basically haven't a clue how to read a set of accounts, do comparatives, draw reasonable conclusions and write an informed article.
Looking over the recent filed accounts the only figure that is in the ballpark of €600k is the current assets figure at November 2012 - €665,739. The largest figure in this category is debtors at €511,847. There is no breakdown given of the €511,847 but I would be of the opinion that it is substantially Europa League money.
I have no information on the Kenny situation.
The figure of €508,685 for accumulated losses at November 2014 is per the balance sheet.
The bank and debtors figures are as follows:
Nov 2010 €13,753 €447,028
Nov 2011 €769,584 €369,640
Nov 2012 €153,381 €511,847
Nov 2013 €85,962 €311,562
Nov 2014 €32,038 €120,334
So yes, the Europa League money is gone.
As I posted earlier, the 2015 accounts are not due to be filed yet so I have no figures. You can draw your own conclusions from the 'investment' that other posters have referred to.
In relation to your point on the 2 teams in 2014, whilst there would have been a cost running a second team you also have to factor in the receipts from the FAI/Liverpool match. I don't have the figures for it and I don't want to reopen the discussion other than to bring it to your attention.
