GFI over 1 when comparing groups for measurement inequivalence in Lisrel?

Just a simple question regarding GFI when comparing groups in Lisrel - I thought GFI should be between 0 and 1 where 1 would mean perfect fit.
How come do I get results over 1 when comparing groups (measurement inequivalence; LX=IN)? Is then 1.08 "same" goodness-of-fit as 0,92?

Here is the example output:
