Commitments and Contingencies(a)Major Customers and Concentration of Credit Risk
One customer accounted for approximately 11% and 12% of total revenue for the years ended December 31, 2025 and 2024, respectively. No customer accounted for 10% or more of total revenues for the year ended December 31, 2023.
As of December 31, 2025, one customer accounted for 12% of our trade accounts receivable, net balance. As of December 31, 2024, two customers accounted for 12% and 11% of our trade accounts receivable, net balance, respectively.
Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and trade accounts receivable. Our cash and cash equivalents have a zero-loss expectation because we maintain minimal balances in our cash and cash equivalents’ accounts and have no history of loss. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S.; therefore, our customers may be similarly affected by changes in economic and other conditions within the industry. We perform periodic evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness to manage this risk. We generally do not obtain collateral for trade receivables, but we may require payment in advance. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide, and the terms of our customer agreements.
(b)Litigation
From time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’s opinion, the resolution of such matters is not expected to have a material adverse effect on our consolidated financial position, results of operations, or cash flows.
(c)Tax Contingencies
Our compliance with federal, state, and local tax regulations is subject to audit by various taxing authorities. Certain taxing authorities have either claimed or issued an assessment that specific operational processes, which we and others in our industry regularly conduct, result in transactions that are subject to taxes. We and others in our industry have disputed these claims and assessments based on either existing tax statutes or published guidance by the taxing authorities.
Our U.S. federal income tax returns for the years 2019 and 2020 currently are under examination by the IRS. The IRS has issued preliminary partnership examination changes, resulted in imputed underpayment computations of approximately $30.3 million, including interest, for the 2019 and 2020 tax years. Under the Bipartisan Budget Act of 2015, there are several procedural steps to complete before a final imputed underpayment, if any, is determined. Based on discussions with the IRS, we have accrued $2.9 million, which we believe is a reasonable estimate of the potential loss from the aggregate final imputed underpayment for the years 2019 and 2020. However, the final partnership imputed underpayment, if any, has not been determined. Once determined, our General Partner may elect to either pay the imputed underpayment, if any, (including any applicable penalties and interest) directly to the IRS or, if eligible, issue a revised information statement to each unitholder, or former unitholder as applicable, with respect to an audited and adjusted return.
(d)Environmental
Our operations are subject to federal, state, and local laws, rules, and regulations regarding water quality, hazardous and solid waste management, air quality control, and other environmental matters. These laws, rules, and regulations require that we conduct our operations in a specified manner and to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections, and other approvals. Failure to comply with applicable environmental laws, rules, and regulations may expose us to significant fines, penalties, and/or interruptions in operations. Our environmental policies and procedures are designed to achieve compliance with such applicable laws, rules, and regulations. These evolving laws, rules, and regulations, and claims for damages to property, employees, other persons, and the environment resulting from current or past operations may result in significant expenditures and liabilities in the future.
