The a/s increase proposed was only up to 350M (of which 20M would be preferred). Not sure where you got the 600M # from?
Anyway, once the r/s was approved the a/s increase was not required/necessary. 1-10 r/s frees up 270M authorized shares and 1-20 r/s frees up 285M authorized, so 270M-285M provides plenty of flexibility.
