Commitments And Contingencies And Other Matters

Note 14 — Commitments and Contingencies and Other Matters

Commitments

In January 2023, we entered into a three-year charter agreement for the Glomar Wave in the North Sea with options to extend. We have long-term charter agreements with Siem Offshore AS for the Siem Helix 1 and Siem Helix 2 vessels expiring in February 2025 and February 2027, respectively, with options to extend. We have time charter agreements for the Grand Canyon II and Grand Canyon III vessels expiring in December 2027 and May 2028, respectively, with options to renew. We also have a time charter agreement for the Shelia Bordelon in the Gulf of Mexico through June 2024 and a short-term time charter agreement for the Horizon Enabler in the North Sea.

Contingencies and Claims

Our contingent consideration liability resulting from the Alliance acquisition is subject to risk, through the remainder of the contingency period, which ends on December 31, 2023, as a result of changes in our probability weighted discounted cash flow model, which is based on internal forecasts, and changes in weighted average discount rate, which is derived from market data.

We believe that there are currently no other contingencies that would have a material adverse effect on our financial position, results of operations or cash flows.

Litigation

We are involved in various legal proceedings, some involving claims under the General Maritime Laws of the United States and the Merchant Marine Act of 1920 (commonly referred to as the Jones Act). In addition, from time to time we receive other claims, such as contract and employment-related disputes, in the normal course of business.

We are currently involved in several lawsuits filed by current and former offshore employees seeking overtime compensation. These suits are brought as collective actions and are in various stages of litigation in federal district courts. We appealed one such lawsuit to the United States Supreme Court, which issued a ruling adverse to us in the first quarter 2023 that is likely to have implications for similar lawsuits in which we are involved. In a separate lawsuit, during the third quarter 2022 the United States Court of Appeals for the Fifth Circuit issued an adverse ruling that may also have implications for other similar lawsuits in which we are involved.
