The interest calculation types of each loan listed in the MEMBER5/MEMBER6 tables are as follows:
 

0 = 365 loans.  The standard daily interest calculation using a 365 or 366-day year. Interest is accrued each day using a per diem interest amount.
2 = None. Interest is not accrued on this loan (used for the write-off loan category).
3 = 360/post. Interest is based on twelve 30-day months, calculated once each month on the specified day for the current month (i.e., interest is paid in arrears).
4 = 360/365. The standard daily interest calculation using a 360-day year (30-day month). Not for mortgage-type loans. Interest is accrued each day using a per diem.
5 = ABD (Average Daily Balance). This is the standard calculation for online credit card loans (Process type V only). This calc type drives the process for applying finance charges. Finance charges are calculated on the billing cycle end date and added to the principal balance.
