GNCP did not enrol in it. The transfer agent enrolled in it in January when it was required for them. In January is when the shares added in August were finally shown which confirms this. Probably a shock to lumb this happened and so they put out a release saying they joined. GNCP does not join with the transfer agent, they can only opt out. Check the rules.
If you check the other companies that the transfer agent services, you can see the day of their updates. There were zero updated since the last GNCP update. I have been tracking it. The latest update for the pink currents of Madison Transfer was yesterday.
However there is a pink current that has not been updated since April on their list.
