NOD looks undervalued on a sum-of-parts basis:
$11.3M net cash
$5M asset sales flagged (Karratha village)
$12M value for McGrath ($4M EBITDA FY14f)
$2M value for Nomad Eastern States
$2M cost savings from elimination of corporate overhead (worth $5M-$6M in value)
Add it all up, you get $30m+ market cap, i.e. 11c/shr. Upside of >60%.
