Explanation

When Paul sells a put option, he is the option writer and receives a premium upfront. The counterparty credit exposure refers to the potential loss Paul would face if his counterparty defaults.

Key Points:

• Paul's position: Short put option
• Counterparty's position: Long put option
• Credit exposure: The amount Paul would lose if the counterparty defaults

Analysis:

1. For a short put position:

   • Paul receives premium upfront
   • Paul has an obligation to buy the stock at strike price if exercised
   • The counterparty has the right, but not obligation, to exercise

2. Credit exposure calculation:

   • Since Paul has already received the premium, he has no credit exposure to the counterparty
   • If the counterparty defaults, Paul keeps the premium and is released from any future obligation
   • The credit risk is actually borne by the counterparty (who faces the risk that Paul might not honor the obligation)

3. Current market conditions:

   • Underlying price (USD 98) < Strike price (USD 125)
   • The put option is in-the-money for the counterparty
   • However, Paul has already been paid and has no further credit exposure

Conclusion:

Paul's counterparty credit exposure is USD 0.00 because he has already received the premium payment and has no further financial obligation that would create credit risk exposure to his counterparty.
