Transactions with Affiliates

Transactions with Affiliates We are a participant in Williams’ cash management program, and we make advances to and receive advances from Williams. At March 31, 2022 and December 31, 2021, our advances to Williams totaled approximately $1,941.7 million and $1,669.4 million, respectively. These advances are represented by demand notes and are classified as Receivables - Advances to affiliate on the Condensed Balance Sheet. Advances are stated at the

historical carrying amounts. Interest expense and income are recognized when earned and the collectability is reasonably assured. The interest rate on these intercompany demand notes is based upon the daily overnight investment rate paid on Williams’ excess cash at the end of each month, which was 0.12 percent at March 31, 2022. The interest income from these advances was minimal for each of the three months ended March 31, 2022 and 2021. Such interest income is included in Other (Income) and Other Expenses – Miscellaneous other expense, net on the Condensed Statement of Net Income.

Included in Operating Revenues on the Condensed Statement of Net Income are revenues received from affiliates of $21.1 million and $2.6 million for the three months ended March 31, 2022 and 2021, respectively. The rates charged to provide sales and services to affiliates are the same as those that are charged to similarly-situated nonaffiliated customers.

Included in Cost of natural gas sales on the Condensed Statement of Net Income are costs of gas purchased from affiliates of $5.4 million and $3.4 million for the three months ended March 31, 2022 and 2021, respectively. All gas purchases are made at market or contract prices.

We have no employees. Services necessary to operate our business are provided to us by Williams and certain affiliates of Williams. We reimburse Williams and its affiliates for all direct and indirect expenses incurred or payments made (including salary, bonus, incentive compensation and benefits) in connection with these services. Employees of Williams also provide general, administrative and management services to us, and we are charged for certain administrative expenses incurred by Williams. These charges are either directly identifiable or allocated to our assets. Direct charges are for goods and services provided by Williams at our request. Allocated charges are based on a three-factor formula, which considers revenues; property, plant and equipment; and payroll. In management’s estimation, the allocation methodologies used are reasonable and result in a reasonable allocation to us of our costs of doing business incurred by Williams. We have recorded approximately $79.6 million and $78.8 million for the three months ended March 31, 2022 and 2021, respectively, for these service expenses, which are primarily included in Operation and maintenance and Administrative and general expenses on the Condensed Statement of Net Income.

We provide services to certain of our affiliates. We recorded reductions in operating expenses for services provided to and reimbursed by our affiliates of $1.6 million and $1.7 million for the three months ended March 31, 2022 and 2021, respectively.

We declared and paid cash distributions to our parent totaling $57.5 million during the three months ended March 31, 2022. During April 2022, we declared and paid an additional cash distribution of $250.0 million to our parent. Our parent made contributions to us totaling $128.0 million and $60.0 million during the three months ended March 31, 2022 and 2021, respectively, to fund a portion of our expenditures for additions to property, plant, and equipment.
