i believe that's subject to change pending the results of an investigation.
Your "belief" is unfounded. The only way they can get back on the Pinks is to find an MM willing to sign off on a Form 211 to bring the company into compliance with Rule 15C2-11.
Given the circumstances--an ongoing investigation--that won't happen.
"i believe that's subject to change pending the results of an investigation."
It has nothing to do with an investigation.
From Release No. 34-63242/November 4, 2010 IN THE MATTER OF 8000, INC.: "Further, brokers and dealers should be alert to the fact that, pursuant to Rule 15c2-11 under the Exchange Act, at the termination of the trading suspension, no quotation may be entered unless and until they have strictly complied with all of the provisions of the rule."
