31 Mar 2018 Statement Now that is really significant in comaprison to what the shares sell for.
Just to be clear - this calcualtion looks at all assets at cost (net of depreciation and writedowns) and less all debts to give you a residual value on winding up an operation. Even if one had to discount the "at cost" 50% there is still a rediculous amount of asset value there to back your cheap shares.
Of course the most recent statements will modify that somewhat - but still not much.
Cheers!
