(1)We determined the interest rates for the related party notes in accordance with the arm’s-length principle set forth in the OECD’s Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (the “OECD Guidelines”), issued January 20, 2022, and the transfer pricing provisions of Section 247 of Canada’s Income Tax Act.
(2)A consolidated subsidiary issued an unsecured promissory note to PAGP. Concurrently, PAGP issued an unsecured promissory note to us for the same face value amounts. We received cash from PAGP of approximately $330 million and $629 million in connection with the related party notes issued in February 2025 and July 2024, respectively, which are reflected in “Proceeds from the issuance of related party notes” (a component of cash flows from financing activities), and we paid equal and offsetting amounts of cash to PAGP, which are reflected in “Investments in related party notes” (a component of cash flows from investing activities) on our Consolidated Statement of Cash Flows.
(3)We assigned PAGP our interest in an existing unsecured promissory note due from a consolidated subsidiary. Concurrently, PAGP issued an unsecured promissory note to us for the same face value amount.
