The table below depicts our contract asset and liability balances at September 30, 2026 and December 31, 2025:

	Contract Assets				Contract Liabilities

During June 2026, we divested certain of our non-core natural gas pipeline and platform assets in our offshore pipeline transportation segment. As a part of this divestiture, we entered into a long-term agreement with the purchaser whereby we will continue to perform operation and maintenance services related to the divested assets. We received total consideration for our future services upon the execution of the agreement and we will recognize revenue associated with the contract over time as services are rendered.

For the nine months ended September 30, 2026 and 2025, we recognized revenue of $20.7 million and $30.5 million, respectively, that was included in contract liabilities at the beginning of the period.
