If a company lost E500k, but has also had E500k invested in it in share capital, then the cash from the latter balances out the former, and so there isn't actually any money owing to anyone. Normally, share capital is only a nominal amount (E100), so there wouldn't be much difference between the two, but here it seems there's a significant amount of share capital.
Or I suppose in simpler terms - if I give you a present of E500, and you spend it, then you've lost E500, but you aren't in debt to anyone.
