### Options

- Suppose that a party wanted to enter into an FRA that expires in 47 days and is based on 129-day LIBOR.The dealer quotes a rate of 4.65 percent

on this FRA. Assume that at expiration, the 129-day LIBOR is 4 percent and the notional principal is $\$25,000,000$.

Calculate the FRA payoff on a long position. - Assume Dell expects to receive 30,000,000 Euro in 120 days. A dealer provides a quote of $\$0,885$ for a currency forward contratct to expire in 120 days.

Suppose that at the end of 120 days, the rate is $\$0.92$. If the settlement is in cash.

Calculate the cash flow at expiration if Dell enters into a forward contract expiring in 120 days to buy dollars at $\$0.885$ - Calculate the payoff at expiration for a call option on the S & P 100 stock index in which the underlying price is 755.21 at expiration, the multiplier is 100, and the exercise price is
