change the ticker? No, not likely.
FINRA does not like dirty shells, and MILV is definitely a DIRTY shell. Furthermore, before NBI can apply to FINRA for a new symbol, it must be a reporting company; MILV has not been a reporting company since 2008. Figuring out the financials and clearing up the debts to clean up this dirty shell would be, at best, a difficult task -- more likely, it would be impossible!
