loanranger, you have found the "true/correct" answer with evidence why SIGO has (so far) not been downgraded from its current OTCQB listing on OTCM (I like that abbrev. rather than typing out the whole proper name every time - lol).
So now anytime someone asks why SIGO has not been downgraded yet from OTCQB status you can point them to your excellently detailed post with the proper answer.
P.S. My count of 45 days would be to March 14 (just after midnight on Jan. 29 to just before midnight on March 14 or maybe SEC uses COB on the 29th as their "technical" deadline, in which case the 45 days would be to March 15).
