Option 1 unlikely. Receivers will either shut the business down or sell it - remote option the directors find a recapitalisation plan and put the company through a deed of company arrangement

Option 2 - doubt this will happen. Would require all debts paid in full incl. professional fees of insolvency professionals and their lawyers as well as interest on NAB and HSBC facilities. All creditors would need to have interest of 8% p.a. paid on their debts as well. Very unlikely someone would buy DSH for $450m+

Option 3 - recoveries possible but monies would go to creditors first. Would need to pursue shareholder class action I would think in order to get anything back
