Nothing official, I've just been seeing it in various company filings over probably the last year in a half or so, where they claim FINRA is denying their name change requests, due to the companies failing to publish required mandatory SEC reports before a Form 15 was filed.
Most people are not aware of this, so your still seeing some of the custodianship shells getting sold, however, the companies get screwed when they try to change the name.
Just another sneaky way for the regulators to try and kill off OTC reverse mergers.
