Answer: Under central clearing, Firm 3's net exposure is AUD O million.

The correct answer to the question is not provided in the file content. However, based on the information given, we can analyze the options and determine the correct statement. Under bilateral netting, the net exposure of a firm is calculated by subtracting the amount it is owed from the amount it owes to other firms. Let's calculate the net exposures for each firm: - Firm 1's net exposure = (Amount owed to Firm 2) - (Amount owed to Firm 3) = AUD 90 million - AUD 12 million = AUD 78 million. - Firm 2's net exposure = (Amount owed to Firm 1) - (Amount owed to Firm 3) = AUD 60 million - AUD 57 million = AUD 3 million. - Firm 3's net exposure = (Amount owed to Firm 1) - (Amount owed to Firm 2) = AUD 70 million - AUD 0 million = AUD 70 million. Now let's evaluate the options: A. Under bilateral netting, Firm 1's net exposure is AUD 28 million. (Incorrect, as calculated above, it is AUD 78 million) B. Under bilateral netting, Firm 2's net exposure is AUD 27 million. (Incorrect, as calculated above, it is AUD 3 million) C. Under central clearing, Firm 3's net exposure is AUD 0 million. (Incorrect, as calculated above, it is AUD 70 million) D. Under central clearing, the CCP's net exposure is AUD 28 million. (This statement cannot be evaluated as there is no information about the central counterparty's (CCP) exposure in the provided content) Since none of the options A, B, C, or D are correct based on the calculations, and the correct answer "96 407" is not explained in the file content, we cannot provide a comprehensive explanation for the correct answer.
