How are bolt FOS's calculated?

I'm curious how bolt FOS's are calculated in Solid Works.

 

My model uses 80% of proof for axial loading (pre-load) which already equates to a maximum FOS of 1.25 (1/.8). Yet when shear and bending moment are taken into consideration, putting the bolt under higher tension, I end up with a higher FOS. ???

 

Can anyone explain?

 

Thanks,
