help with edate formating :-)

Hello all, I have an name in a1, a date in a2 and a number in a3. ( Tom 03-17-11 1 ) . I would like the a3 cell to go a 1- , that is drop off one year after the date in a2. I have used =edate(a2,12) in cell b2. Can I turn the 1 that is in a3 into a 1- when b2 get to 03-17-12.
PS. This is my first post. I have seen some great thing in this forum and look forward to learning alot and even helping when I can :-)

Thanks for the help. I got an error with this formula, however it did get me on the right track.
B2 cell is =edate(a2,12) C2 cell is =if (TODAY()>B2),-1,0. I will end up with two rows however it should serve my needs.

Thanks again. Can I send you the finished setup? There may be an easier way then what I came up with.

If you don't want the extra column then combine your B2 and C2 formulae:

In B2: =IF(TODAY()>EDATE(A2,12),-1,0)
