1.

Using the Black Scholes formula, calculate the price of a 4-month European call option on the British pound. You are given the following details: The current exchange rate is 1.3, the exercise price is 1.3. The risk free interest rate in the United States is 3% per annum whereas the risk free rate in Britain is 4% per annum. The annualized implied volatility in the exchange rate is 20%. The European call option price is:
- A.
  
  6.1 cents
- B.
  
  5.7 cents
- C.
  
  5.3 cents
- D.
  
  4.9 cents
2.

What are the values of u, d and p when a binomial tree is constructed to value an option on a foreign currency. The tree step size is 1 month, the domestic interest rate is 5% per annum, the foreign interest rate is 8% per annum, and the volatility is 12% per annum.
- A.
  
  1.035, 0.966, 0.455

3.

Use the conventional binomial tree method with n=3 steps to calculate the price of a 4-month American put option on the British pound. You are given the following details: The current exchange rate is 1.3, the exercise price is 1.3. The risk free interest rate in the United States is 3% per annum whereas the risk free rate 4% per annum. The annualized implied volatility in the exchange rate is 10%. The price of the American put option is:
- A.
  
  2.7 cents
- B.
  
  2.9 cents
- C.
  
  3.2 cents
- D.
  
  3.4 cents
4.

Recalculate the price of the American put option given in question 3 above using n=30 steps. Hint: use Mark Broadie’s efficient Binomial tree method. What is the price of the option:
- A.
  
  3.1 cents
- B.
  
  3.2 cents
- C.
  
  3.3 cents
- D.
  
  3.4 cents
5.

The difference between the value of an European Call option calculated by the Black-Scholes formula and that calculated using Binomial trees arises because the Binomial Tree method uses a discrete number of times steps where Black Scholes assumes continuous hedging and rebalancing of the portfolio.
- A.
  
  True
- B.
  
  False
6.

For an American option the value of the option at a node other than the terminal node is:
- A.
  
  The expected present value of option at successor nodes
- B.
  
  The payoff from early exercise
- C.
  
  The minimum of the expected present value of option values at successor nodes or the payoff from early exercise
- D.
  
  The maximum of the expected present value of option values at successor nodes or the payoff from early exercise
- E.
  
  None of the above
7.

For a European up-and-out call option the option will only be exercisable and exercised at expiry if:
- A.
  
  The barrier is reached during the tenor of the option and the spot price on maturity is less than the strike price
- B.
  
  The barrier is reached during the tenor of the option and the spot price on maturity exceeds the strike price
- C.
  
  The barrier is not reached during the tenor of the option and the spot price on maturity exceeds the strike price
- D.
  
  The barrier is not reached during the tenor of the option and the spot price on maturity is less than the strike price
- E.
  
  None of the above
8.

- A.
  
  True
- B.
  
  False
9.
