30/360. Method whereby interest is calculated based on a 30-day month and a 360-day year. If the accrual period ends on a 31st, do not change the date unless the period started on a 30th or 31st, in which case change the end date to 30th. In addition, if the accrual period ends on the last day of February, the month of February should not be extended to a 30 day month. |
A002 |
30/365. Method whereby interest is calculated based on a 30-day month and a 365-day year. |
A003 |
30/Actual. Method whereby interest is calculated based on a 30-day month and the assumed number of days in a year, i.e. the actual number of days in the accrual period multiplied by the number of interest payments in the year. Eg, a semi-annual bond (one paying two coupons per year) can display a period between coupons of 181 to 184 days. In this case, the number of days in a year will be 362 to 368 days. |
A004 |
Actual/360. Method whereby interest is calculated based on the actual number of accrued days and a 360-day year. |
A005 |
Actual/365. Method whereby interest is calculated based on the actual number of accrued days and a 365-day year. |
A006 |
Actual/Actual (ISMA). Method whereby interest is calculated based on the actual number of accrued days and the assumed number of days in a year, i.e. the actual number of days in the accrual period multiplied by the number of interest payments in the year. |
A007 |
30E/360 or Eurobond basis. Method whereby interest is calculated based on a 30-day month (no exceptions, i.e. February should always be extended to a 30-day month) and a 360-day year. |
A008 |
Actual/Actual (ISDA). Method whereby interest is calculated based on the actual number of accrued days (falling on a normal year) divided by 365, added to the actual number of days (falling on a leap year) divided by 366. |
A009 |
Actual/Actual (basic rule). Method whereby interest is calculated based on the actual number of accrued days and a 365-day year (if payment date is NOT in a leap year) or a 366-day year (if payment date is in a leap year). |
A010 |
Actual/Actual (AFB). Method whereby interest is calculated based on the actual number of accrued days and a 366-day year (if 29 Feb falls in the accrual period) or a 365-day year (if 29 Feb does not fall in the accrual period). |
