Dave, it is probably a good idea to consider the actual length of time that a stock needs to close at below the $1 thresehold before the company even receives a notice. 30 business days from Friday takes us to ??? before a notice is even issued then add 180 calander days (about 6 months from mid Jan).
If a company trades for 30 consecutive business days below the $1.00 minimum closing bid price requirement, Nasdaq will send a deficiency notice to the company, advising that it has been afforded a "compliance period" of 180 calendar days to regain compliance with the applicable requirements.
