The Company enters into foreign currency forward contracts from time to time to help mitigate the impact that an adverse change in foreign exchange rates would have on the value of the Company’s investments denominated in foreign currencies. In order to better define its contractual rights and to secure rights that will help the Company mitigate its counterparty risk, the Company entered into an International Swaps and Derivatives Association, Inc. Master Agreement (the “ISDA Master Agreement”) with its derivative counterparties, Bank of New York Mellon, Wells Fargo Securities, LLC and ING Capital LLC. The ISDA Master Agreement permits a single net payment in the event of a default or similar event. As of June 30, 2025, no cash collateral has been pledged to cover obligations and no cash collateral has been received from the counterparty with respect to the Company’s forward currency contracts.
