Thx @ triage & observing for the securded unsecured and trade creditor explanation... I think i get it but the question is.. Why has troy so much unsecured trade creditor debt? Debt is debt... Secured or unsecured... Doesn't matter... If I'm right the trade creditor debt contains supplier, machines for mining and so on... Why is this so much... Troy is for example not a standard producer which has 200t open steel bills or copper... I don't get why these debt is so high?
