Interest shall accrue from the date of the borrower’s actual drawdown, calculated based on the actual amount drawn down and the number of days the funds are used.

☐ Combined simple and compound interest calculation: for the portion calculated based on the pricing benchmark, the interest for that portion on each business day = (principal amount borrowed + total accrued interest for that portion up to the previous day) x the applicable benchmark daily interest rate for that day; on non-business days, interest shall still accrue on a simple interest basis. The portion calculated based on the margin shall accrue interest on a simple interest basis.

The daily interest rate calculation basis is 360 days per year, with the conversion formula: daily interest rate = annual interest rate / 360.

The business days referred to above shall mean business days in the jurisdiction of the relevant currency pricing benchmark administrator.
