Hilo Jenny, would like to seek you advice on below question of practice exam. A derivative trading firm buys a European-style call option on stock JKJ with a time to expiration of 9 months, a strike price of EUR 45, an underlying asset price of EUR 67, and implied annual volatility of 27%. The annual risk-free interest rate is 2.5%. What is the trading firm’s counterparty credit exposure from this transaction? If there is any additional info required for the calculation, please make it up. Many thanks.
