why the less than half a cent trades?

maybe i missed someone's explanation some months back, but how is it that BEPPA is able to trade all these many months at increments of less than 1/2 a cent - i thought the rule was, once a stock hits 10 cents, then all moves beyond 10 cents are in steps of at least 1/2 a cent

and thanks to whoever can solve this incredibly important mystery affecting none other than our contentious BEPPAs, the answer to which will no doubt have many a BEPPA holder perched in wide-eyed anticipation...

good luck
