By my calculation
As at 31/12/11 current face value per share is
229338(face value) - 139458(liabilities) = 89880 (net asset)
89880 / 176440 = .509
So there, we have it.
current face value per share as at 31/12/11 is $0.509, current NTA as at 31/12/11 is $0.348 and current share price as at 28/02/12 is $0.175
