Although these standard profiles are reestimated from time to time, under the best scenario they can only approximate the disbursement pattern of any single loan. Most projections of future debt service payments generated by the RXD system are based on the repayment terms of the loans. Using the first and final payment dates and the frequency of the payments, the system calculates the stream of principal payments due. If future payments are irregular, the RXD system requires a schedule. Projected future interest payments are calculated similarly.
Interest is based on the amount of debt disbursed and outstanding at the beginning of the period.
Again, using the first and final interest payment dates and the frequency of payments, the system calculates the stream of interest payments due. If interest payments are irregular, the RXD system requires a schedule. The published figures for projected debt service obligations are converted into U.S. dollars using the end-December 1996 exchange rates.
