If the deal is unlocked and you attempt to edit the existing fields to add principal or apply reset rates, you will receive a message indicating that making a change will lock this deal. After the deal is locked, you cannot change your selections on the Deal Details page. For IRP and IR swap deals, you can review and modify interest payment dates, amounts, and reset dates on the Interest and Payment Dates page. If the deal is amortized, this page shows the amortization schedule.
Initially, all the details on the Interest and Payment Dates page are system-generated. Use this page to view and manage interest information for a specific deal. The types of changes you can make depend on the type of deal and whether payments have been already paid, reconciled, or accounted for.

Rate Set |
The Rate Set check box is automatically selected for interest periods for which the rate is set. Set rates exist for all interest periods for fixed legs. You set reset rates for floating legs as you reach reset dates. When you reach floating-leg reset dates, select the Rate Set check box, enter the rate, and click Save. The system uses the rate to calculate a payment or receipt amount. If the cash flow is Firm, an accounting event is generated if you select Rate Set. If the cash flow is Provisional and the Reset Rate Set check box on the Reset Rates page is deselected, no accounting event is generated if you deselect Rate Set. These attributes will change only after the real rate comes in from the market. Accounting payments will all occur only after the real rate is set. Note: The Rate Set check box may not be available for a deal, depending on the setting that you have specified with the Allow Fixed Rate Change check box at the instrument level. |
Reset Date |
The date that interest rate is reset. This is available for IR swap deals and IRP floating-rate deals only. |
Rate from Source |
Initially, the Rate populated on the Deal Detail page is defaulted to all interest periods in the future. Modify the rate from source as applicable. The system uses the rate to calculate a payment or receipt amount. |
Index Margin |
For interest calculations, the index margin is the value that is added to the Rate from Source, or the value by which the Rate from Source is multiplied. You can override the margin for one or more interest periods. |
Rate |
This field shows the adjusted interest rate inclusive of the margin. |
This section discusses viewing and editing margins. You can view the interest rate for a period without the margin applied, view and adjust the margin applied to each interest period, and adjust the index margin for one or more interest periods.
When you save margin adjustments, the margin is used to recalculate interest payments for the affected interest period(s).
Note: The information in this section is relevant only for floating-rate IRP and IR swap deals.

Adjusting Principal on Amortized Deals
For amortized deals, the Interest and Payment Dates page displays a comprehensive, payment-information schedule for the method of amortization that is selected in the Amort Method field on the Deal Detail page.
If you select the Constant Payment or Constant Term method of amortization, you can adjust the principal amount and payment date in the Add Principal Paydown/Drawdown section as follows:
In the Payment Type field, select Drawdown or Paydown.
Add the Payment Date.
Enter the amount in the Principal Amount field.
Click the Add Paydown/Drawdown button.
The system creates a new row in the Details grid with the payment type you have created. Deal processing recalculates the payment schedule based on the new paydown or drawdown.
If you select a Factored or Fixed Paydown method, however, you must enter additional values so that the system can correctly calculate the factored or fixed paydown amortization amount.
Fixed Paydown Amortization
If the amortization method is fixed paydown, you can add a paydown/drawdown by percentage or amount.
To enter a fixed paydown value in the Add Principal Paydown/Drawdown section:
Enter a value in the Percentage field or the Principal Amount field.
Add the payment date.
For IR swap deals, select Pay or Receive in the Leg field.
Click the Add Paydown/Drawdown button.
Factored Amortization
To enter a factored value in the Add Principal Paydown/Drawdown section:
In the Payment Type field, select Drawdown or Paydown.
To establish accreting factors, select Drawdown. The system then uses the factor as an accreting (not amortizing) factor.
