I called the OTC and got the following (paraphrased).
Me: "I own a stock, symbol CTIX, and noticed it went from OTCQB to OTC pink can you tell me why? " OTC : "We made some changes which required submitting a new application. It looks like CTIX did not submit an application." Me:"Were there new fees attached?" OTC: "Yes $10,000 for new applications and $7,500 for current QB renewal. There were 90 days to renew and CTIX simply did not file to renew" Me: "Thanks"
The signs read "Don't feed the Bears" I think they mean don't even feed them small things. CTIX was OTCQB before so I think it should give them the benefit of the doubt though.
