Multicurrency Bonds 
When calculating the net present value of the interest cash flow you must differentiate between four sets of circumstances for the determination of the interest amount:
Interest amount |
Exchange rate - nominal currency/cash flow currency - fixed |
Exchange rate - nominal currency/cash flow currency - variable |
Interest rate fixed |
The interest amount converted at the agreed exchange rate from the nominal amount currency to the cash flow currency is discounted in the cash flow currency on the horizon and then converted at the exchange rate valid on the horizon from the cash flow currency to the evaluation currency. |
The interest amount converted at the forward exchange rate valid on the cash flow due date from the nominal amount currency to the cash flow currency is discounted in the cash flow currency on the horizon and then converted at the exchange rate valid on the horizon from the cash flow currency to the evaluation currency. |
Interest rate variable |
The interest amount converted at the agreed exchange rate after cancellation of the variable reference interest rate from the nominal amount currency to the cash flow currency is discounted in the cash flow currency on the horizon and then converted at the exchange rate valid on the horizon from the cash flow currency to the evaluation currency. |
The interest amount converted after cancellation of the variable reference interest rate at the forward exchange rate valid on the cash flow due date from the nominal amount currency to the cash flow currency is discounted in the cash flow currency on the horizon and then converted at the exchange rate valid on the horizon from the cash flow currency to the evaluation currency. |
