The only risk I can see the restatement of accounts......
Either 1) Wait for restatement... see if OK and buy more with complete confidence. 2) Buy anyway... no-one can make a case for amortization being a significant change to EPS.
It's 8% of my portfolio... I'm a happy holder... and if I had some money today.. it would be one of the ones I would strongly consider adding to. It looks like from your messages you've already discovered PUDA :-)
