Segment Information and Customer Concentration SEGMENT INFORMATION AND CUSTOMER CONCENTRATION
 
We have determined that we operate as a single operating and reportable segment. The measure of profit and loss regularly provided to the chief operating decision maker (“CODM”) that is most consistent with GAAP is net income, as presented in our Consolidated Statements of Operations. This measure contributes to the CODM’s assessment of performance and resource allocation, which includes monitoring of budget versus actual results, establishing compensation and deciding on capital allocation priorities. Significant expenses regularly provided to the CODM, and included in the measure of profit and loss, are cost of sales, operating and maintenance expense and general and administrative expense, as reported in our Consolidated Statements of Operations. Included in the measure of profit and loss are significant noncash items of changes in the fair value of our derivative instruments, which were $159 million and $119 million in gains for the three and six months ended June 30, 2025, respectively, and $104 million and $147 million in gains for the same periods of 2024, respectively. Interest income, which is included in interest and dividend income on our Consolidated Statements of Operations, was
$2 million and $6 million for the three and six months ended June 30, 2025, respectively, and $9 million and $18 million for the same periods of 2024, respectively.

The measure of segment assets is reported on our Consolidated Balance Sheets as total assets. Substantially all of our tangible long-lived assets, which consist of property, plant and equipment, are located in the United States. Total expenditures for additions to long-lived assets is reported on our Consolidated Statements of Cash Flows.

The concentration of our customer credit risk in excess of 10% of total revenues and/or trade and other receivables, net of current expected credit losses and contract assets, net of current expected credit losses was as follows:
