What is the correct answer for percent change when the start amount is zero dollars $0?
Anyone who has any business looking at growth numbers will know thay are meaningless in the first year,  So all they need to know is that it's the first year.    It's no different than the Billboard music charts' treatment of the "last week's chart ranking" and "movement up/down" columns.  It will help with visual layout if the figure used is about the same size as a percentage number.   "New" fits nicely.
