As part of our normal business activities, we may be named as defendants in legal proceedings, including those arising from regulatory and environmental matters. Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to fully indemnify us against losses arising from future legal proceedings. We will vigorously defend the Partnership in litigation matters.

We have long-term and short-term payment obligations under debt agreements. In total, the principal amount of our consolidated debt obligations were $33.9 billion and $32.2 billion at September 30, 2025 and December 31, 2024, respectively. See Note 7 for additional information regarding our scheduled future maturities of debt principal.
