If a company has up-to-date financials filed w/ the SEC, their stock could be quoted as an unsolicited pinkie shortly after an SEC suspension. Since CKYS is a non-reporting pinkie, they'll definitely come back as a grey. To return on the pinks, they have to go thru the approval process again. This means a broker has to comply w/ Rule 15c2-11 and file a Form 211 to NASD's OTC Compliance Unit for approval. The process can take quite awhile like in months or years. It's pretty slow.
