Unfortunately many leased items are rarely able to produce an income or realise a "sale price" if the original purpose is gone. Thus more often than not, its asset value is almost impossible to reliably be assertained by the business let alone by an external party. For example if all these aeroplanes i have have an income producing capability of producing n $millions but my business can't use them at a profit because of competition, how are the aeroplanes "asset" value ever going to be realised? they are effectively worthless. So the balance sheet should show them at a high figure when business is good, and when business goes down the toilet they should be written off as they can't even be sold.
