1.1.1 Concept of Main Interest

If a product, and hence a contract involving the product, has more than one type of interest applicable, you should designate one of them as the main interest. You can do this while defining the interest details for the product. For capitalization and amortization (repayment in equated installments) purposes, the main interest component is considered.

Commission, if any, can be defined as another interest rule (It is a rate and is tenor based like interest and can be processed similarly). For example, you can define your main interest as a rule with ID INT1 and your commission can be defined as another interest rule with rule ID INT2. You can have as many interest rules as you want to apply on the product and the contract.
