Ann: 2015 AGM Chairman and Managing Directors Address, page-4

To a degree, operating EBIT just needs to remain flat whilst asset sales convert unused Non-Current Assets to cash (or reduce NIBD).

Should this play out the way @madamswer described previously, the ~47cps in Net Assets can ultimately be returned to shareholders via:
- Share buybacks
- Return of Capital
- Franked dividends

As I see it, the main threat is not a declining EBITDA, but rather the failure to realise the book value of cranes and to do so in a reasonable timeframe. To date, management have done OK (although quite slow), as asset impairment has not been substantial (in some cases, profits have been booked).
