Calculating a Forward Starting Swap with Forward Equations

Hi,

I have been trying to resolve this problem for some time but I cannot get the correct answer. The problem is the following one.

Compute the initial value of a forward-starting swap that begins at t=1, with maturity t=10 and a fixed rate of 4.5%. (The first payment then takes place at t=2 and the final payment takes place at t=11 as we are assuming, as usual, that payments take place in arrears.) You should assume a swap notional of 1 million and assume that you receive floating and pay fixed.)

We also know that:

r0,0=5%, u=1.1, d=0.9 and q=1−q=1/2.

Using forward equations from t=1 to t=9 I cannot resolve the problem:

Here is what I have done in Excel with a final result of -31076 but it is not the correct answer:

Thank you

anyone?

Valuing a swap isn’t a Level I topic; it’s a Level II topic.
