There has been no delay in hiring of a new auditor.
Some speculated it would be announced at earnings, but CVVT never even implied that.
They stated they expected it to be announced the end of March...while the 10K was due the middle of March.
During the C.C. they stated while they can not guarantee anything, they expected to announce a "letter of engagment" very soon.
It appears to me the company is doing everything in their power to shore up their weak accouting standards. No on complained about his until recently, so growing the company seemed to be more important. Only lately has this become a red hot issue, and the company is responding just about as fast as you can reasonable expect them too. You can't change auditors overnight.
As a side note, this is getting rather cheap. By my esitmates they'll have more than the current market cap in cash alone in about 2 years from now (never mind all their other assets and the fact they'll make north of 50M a year going forward from there).
Doesn't mean this isn't going lower, but it sure starting to look like a pretty compelling long term buy at the moment.
