Is this the coating starting to crack on my 16-50 F/2.8?

Starting up my seasonal part time gig as a kids sports photographer, and ran across this while giving everything the once over.  What am I dealing with here?  Only on the front element, and interesting this lens has always had a protective filter on it, so it’s equally confusing.
