huge increase in ntab

Although PRV comments on HC are as rare as hens teeth, there must be some financial gurus out there who can comment on the huge recovery in the NTAB.

I haven't owned any PRV for a couple of years and was surprised to see the NTAB go up from 87.8 cents on 30/11/09 to 96.9 cents on 31/12/09 [9.1 cent increase] while the share price is still stuck back in the low 70s.

After a lean period I also note that PRV has just paid a 3.5 cent interim dividend

I was never very good at maths, but I looked at the NTAB history of PRV over the past 2 years, before and after the financial crisis [if it is over], and I think I like what I see.

Are PRV doing something right and have they turned the corner?

I would appreciate any comments.
