30 consecutive days under $1 and then 90 days after that NASDAQ begins the process of delisting. If during those 90 days AFFY stock is over $1 for 10 consecutive days then AFFY won't be delisted.
CYTK is an example of stock which was under a dollar for a while and had 10 days over $1 to stop the delisting talk.
So you have until Mid-May to even start to think about this and then three months after that before anything happens. By that time, we should have news on the .012% (one thousandths of one percent) of deaths and if the news is good which I expect it to be then delisting will be out of the question.
