This only effects non 401K/sponsored retirement accounts. It will have zero effect on the OTC, re-read the doc...brokers are already prohibited from pushing unsuitable garbage to retirees, this just requires them to disclose their fees and conflicts of interest...
That is the least of Windstream's worries Beachside. I doubt Windstream was pushed by many brokers for any accounts retirement or not. It was the mailer done and mailed by a 3rd party that caused all the trouble here.
We might be bankrupt here , might dilute to no value over time or might turn who knows but I am sure they are not worried about brokers recommending or not recommending the stock at this point.
