Forward Curve C11 to C22: Implied forward interest rates for the respective periods. 16
Worksheet 6: FRA Hedge 1. Overview This model calculates the effective interest rate for a forward-starting borrowing or investment, which is linked to a future floating rate (e.g. LIBOR) plus/minus a margin and hedged with a Forward Rate Agreement (FRA). The model can also be used simply to calculate the net settlement of a FRA, ignoring any underlying exposure to interest rates. The worksheet also contains a data table showing the effective borrowing/investment rate achieved, given a range of possible values for the future floating interest rate. N.B. If the underlying loan/deposit has been perfectly hedged, the effective rate should be equal to the fixed rate of the FRA in cell C15 plus/minus the margin in cell C8, regardless of the future floating rate. This can also be seen in the associated graph. 2. Inputs C3: The type of underlying transaction being hedged, i.e. select loan (borrowing) or deposit (investment). 17
C4: The principal amount of the loan or deposit in millions, e.g. insert 100 for 100 million. C5: The term of the forward period in days. C6: The day base/annualised basis for the relevant currency, e.g. select 360 for USD and 365 for GBP. C8: The interest margin above/below the floating rate, expressed as an annualised percentage. C11: The FRA position, i.e. buy or sell. N.B. If a loan is being hedged, select buy and, if a deposit is being hedged, select sell. C12: The notional principal of the FRA in millions, which should match the number in cell C4. C13: The term of the FRA in days, which should match the number in cell C5. C14: The day base/annualised basis for the relevant currency, e.g. select 360 for USD and 365 for GBP. C15: The FRA fixed rate. F4: The realised value of the future floating rate (e.g. LIBOR, EURIBOR etc.) as an annualised percentage, e.g. insert 5 for 5%. You may insert any rate you wish here. 18
3. Outputs C7: The realised future floating rate, which is linked to cell F4 and which is used to calculate the loan/deposit interest. C9: The interest payable/receivable on the underlying loan/deposit. C16: The realised future floating rate, which is linked to cell F4 and which is used to calculate the settlement amount of the FRA. C17: The discounted net settlement of the FRA. C18: The undiscounted net settlement of the FRA. N.B. Although FRAs are settled on a net discounted basis, this undiscounted amount makes the FRA settlement cash flow directly comparable to the interest on the underlying loan/deposit, which is settled on an undiscounted basis, i.e. at the end of the forward period. C20: Interest on loan/deposit. C21: Undiscounted FRA settlement cash flow. C22: Net cash flow between cells C20 and C21. C23: The effective annualised interest rate of the loan/deposit, based on the net cash flow in cell C22, the principal in cell C4, the term in cell C5 and the day base in cell C6. 19
Worksheet 7: Futures Hedge 1. Overview This model calculates the effective interest rate for a future borrowing or investment that is linked to a future floating rate (e.g. LIBOR), plus/minus a margin, and hedged with a Short- Term Interest Rate Futures Contract (STIR). N.B. Since the futures contract expires in 20 days time, it is assumed that the interest rate of the future underlying loan/deposit is also determined on that date and matches the settlement rate used to calculate the futures Exchange Delivery Settlement Price (EDSP). The model can also be used simply to calculate the net profit or loss of a STIR, ignoring any underlying exposure to interest rates. The worksheet simulates the daily closing prices of the futures contract in order to demonstrate the daily variation margin cash flows. The associated graph shows the price changes of the futures contract over the 20 day period from when the position is opened until expiry. If the underlying loan/deposit has been perfectly hedged, the effective rate in cell C21 should be equal to the rate implied in the opening price of the STIR (cell C14) plus/minus the margin in cell C7, regardless of the future floating rate. 20
2. Inputs C3: The type of underlying transaction being hedged, i.e. select loan (borrowing) or deposit (investment). C4: The principal amount of the loan or deposit in millions, e.g. insert 100 for 100 million. C5: The term of the forward period in days. N.B. If the term of the forward period is not exactly a quarter of a year, i.e. 90 days for a 360 day base or 91.25 days for a 365 day base, the futures hedge will not be perfect, as these contracts are based on a forward period of precisely this term. In such instance, there is basis risk in the hedge and the effective rate in cell C21 will fluctuate, depending on the futures EDSP. Try it! C6: The day base/annualised basis for the relevant currency, e.g. select 360 for USD and 365 for GBP. C7: The interest margin above/below the floating rate, expressed as an annualised percentage. C11: The number of futures contracts traded, inserted as a positive number irrespective of whether these contracts are bought or sold. The number of contracts multiplied by the notional principal per contract should equal the principal of the underlying loan or deposit. For example, if the underlying principal in cell C4 is 100, i.e. 100 million, and the currency is USD, the number of Eurodollar futures traded should be 100, since the notional principal per contract is USD 1 million. N.B. Take care when calculating the required number of contracts for Short Sterling (notional principal GBP 500,000) and Euroyen (JPY 100,000,000). C12: The futures position, i.e. buy (long) or sell (short). N.B. If a loan is being hedged, select sell and, if a deposit is being hedged, select buy. 21
C13: The point value of the contract, e.g. select 25 (USD 25) for Eurodollar futures. C14: The opening price at which the futures contracts are bought/sold. J4: The realised value of the future floating rate as an annualised percentage, e.g. insert 5 for 5%. This will then determine the final closing price of the futures contract on the expiry date (day 20), known as the Exchange Delivery Settlement Price (EDSP). You may insert any rate you wish here, but if it is very different to the rate implied in the futures closing price on day 19, expect a big change in the futures price on day 20 and a resulting large variation margin cash flow. 3. Outputs C8: The realised future floating rate expressed as an annualised percentage, which is linked to cell J4. C9: The interest payable/receivable on the underlying loan/deposit. C15: The final closing price of the futures (EDSP), based on the realised floating rate in cell J4. C16: The net amount of the daily variation margin cash flows. C18: Interest on loan/deposit. C19: The profit or loss on the futures position, i.e. the net amount of the daily variation margin payments in cell C16. C20: The net cash flow between cells C18 and C19. 22
C21: The effective annualised interest rate of the loan/deposit, based on the net cash flow in cell C20, the principal in cell C4, the term in cell C5 and the day base in cell C6. 23
Worksheet 8: Swap Pricer 1. Overview This model calculates the fixed rate of a 2-year quarterly-reset Interest Rate Swap (IRS) against a 3-month floating interest rate. The swap rate is calculated according to the noarbitrage principle known as The Law of Equivalent Value see below. N.B. ACI Dealing Certificate candidates are not required to calculate IRS prices and this model is provided for interest only. 2. Inputs B4 to B11: These cells contain the principal amount of the swap in millions, at each of the reset dates. N.B. For a vanilla swap, these amounts are constant. For an amortising or accreting swap, however, these amounts will decrease or increase over time. D4 to D11: These cells contain the number of days in each of the respective 3-monthly periods, e.g. 90, 91 etc. 24
E4: This cell contains the current 3-month cash money market interest rate expressed as an annualised percentage, e.g. insert 0.30 for 0.30%. E5 to E11: These cells contain the forward interest rates for the respective periods expressed as an annualised percentage, e.g. insert 0.30 for 0.30%. N.B. In practice, these rates would be obtained from the implied money market forwardforward calculations, or from the relevant FRA rates if available. C13: The day base/annualised basis for the relevant currency, i.e. select 360 for USD and 365 for GBP. 3. Outputs F4 to F11: These are the spot discount factors for each of the respective periods and forward rates. These are required to calculate the present values of the fixed and floating cash flows in columns G and H. G4 to G11: Using the spot discount factors above, these cells contain the present value of the respective future floating rate payments of the swap, estimated by reference to the current forward rates in column E. H4 to H11: Using the spot discount factors above, these cells contain the present value of the respective fixed rate payments of the swap, calculated by reference to the fixed swap rate in cell D15. D14: This cell contains the fixed rate of the swap using a closed-form approximation. This will only be precise if the number of days in each of the periods is exactly a quarter of a year (90 or 91.25 days, depending on the day base of the currency). D15: This cell contains the precise fixed rate of the swap, based on the equivalence of the sum of the present values of the fixed and floating legs of the swap see cells G13, H13 and G14 below. 25
G13: This cell contains the sum of the present values of the floating leg payments. H13: This cell contains the sum of the present values of the fixed leg payments. G14: This cell contains the net of G13 minus H13. N.B. The fair value of the fixed rate of the swap, i.e. ignoring any margin for the market maker, should be at a level which leads to the value in cell G14 equalling zero. To find this rate, proceed as follows: Click on cell G14 Click on Data on the worksheet Toolbar Click on What-If Analysis under Data Tools Select Goal Seek Set cell G14 to value 0 by changing cell D15 26

The points should be inserted in the same terms as the exchange rate and with the appropriate sign. For example, EUR/USD points of -55 should be inserted as -0.0055. C5 and D5: The bid and offer swap points to the far date of the forward period. N.B. The points should be inserted in the same terms as the exchange rate and with the appropriate sign. For example, EUR/USD points of -55 should be inserted as -0.0055. 40
3. Outputs C6 and D6: The bid and offer forward-forward FX swap points. C7: The near date rate of the forward-forward swap bid, i.e. where the forward trader is first selling and later buying the base currency. N.B. As per market convention, this is the mid-rate of the forward outright to the near date of the forward-forward swap. C8: The far date rate of the forward-forward swap bid, i.e. where the forward trader is first selling and later buying the base currency. This is calculated as the near date rate adjusted by the forward-forward swap bid points. D7: The near date rate of the forward-forward swap offer, i.e. where the forward trader is first buying and later selling the base currency. N.B. As per market convention, this is the mid-rate of the forward outright to the near date of the forward-forward swap. D8: The far date rate of the forward-forward swap offer, i.e. where the forward trader is first buying and later selling the base currency.

Worksheet 14: NDF Settlement 1. Overview This model calculates the settlement amount for a non-deliverable FX forward (NDF). N.B. The calculation is based on the nominal of the contract being expressed as an amount of base currency. 2. Inputs C3: The contracted rate of the NDF. C4: The base currency position of the contract, i.e. select long or short. C5: The nominal value of the contract in base currency millions. N.B. If the nominal value of the contract is expressed as an amount of counter-currency, first convert this into the equivalent amount of base currency by dividing by the NDF rate. This amount can then be inserted into the model. C6: The fixing rate of the NDF, i.e. the future spot rate against which the NDF settles. 42
3. Outputs C7: The settlement amount of the NDF, expressed as an amount of base currency in millions. N.B. If this amount is positive, the position holder specified in cell C4 receives this and, if negative, pays this. 43
