Estimate the capital required under Basel I for a bank that has the following transactions with another bank (assume no netting):

(a) a 2-year forward contract on a foreign currency, currently worth $2 million, to buy foreign currency worth $50 million;

(b) a long position in a 6-month option on the S&P 500 with a principal of $20 million and a current value of $4 million;

and

(c) a 2-year swap involving oil with a principal of $30 million and a current swap value of -$5 million. What difference does it make if the netting amendment applies?
