[AMOS] No BIC value given

I would like to test two different (and competing) CFA-models in AMOS. Both of the these used the same nine manifest variables. In one of them, there are four latent variables, in the other two. After doing some (admittedly not extremely thorough) research on model comparisons I had planned to compare the BIC values of the two models. Unfortunately, AMOS does not give me any BIC values. What could be/is the reason for this? (Note: I am not using several groups.)

Any help with this would be really appreciated.
