How SAS studio calculates BIC in proc mixed?

Dear All,

 

I am trying to understand the way that BIC is calculated for a mixed model using PROC MIXED, I arrived to the  AIC reported by SAS under the ML and REML version.

 

However when i tried manually to calculate the BIC it seems that it is penalized with a function of log(n^2) instead of log(n), being n the number of subjects.

 

Could somebody iluminate me how  SAS calculates BIC under ML and REML? 

 

I am using the currently studio version,

Thanks a lot for your help
