2. REVENUE, CONTRACT ASSETS AND LIABILITIES AND OTHER CONTRACT MATTERS

As discussed in Note 1, we recognize revenue from our contracts in accordance with Topic 606. Summarized below are required disclosures under Topic 606 and other relevant guidance.

Disaggregation of Revenue

Future Performance Obligations

Contracts Assets and Liabilities

The timing of customer invoicing and recognition of revenue using the POC method may occur at different times. Customer invoicing is generally dependent upon contractual billing terms, which could provide for customer payments in advance of performing the work, milestone billings based on the completion of certain phases of the work, or billings when services are provided. Revenue recognized in excess of amounts billed is reflected as contract assets on our Balance Sheet, or to the extent we have an unconditional right to the consideration, is reflected as contract receivables on our Balance Sheet. Amounts billed in excess of revenue recognized, and accrued contract losses, are reflected as contract liabilities on our Balance Sheet. Information with respect to contracts that were incomplete at March 31, 2024 and December 31, 2023, is as follows (in thousands):

Allowance for Doubtful Accounts and Credit Losses

Our provision for bad debts and credit losses is included in other (income) expense, net on our Statement of Operations, and for the three months ended March 31, 2024 and 2023, was not significant. Our allowance for doubtful accounts and credit losses at March 31, 2024 and December 31, 2023, was $0.2 million and $0.2 million, respectively. We had no significant write-offs or recoveries of previously recorded bad debts during the three months ended March 31, 2024 or 2023. See “New Accounting Standards” in Note 1 for discussion of our adoption of ASU 2016-13.

Variable Consideration

For the three months ended March 31, 2024 and 2023, we had no material amounts in revenue related to unapproved change orders, claims or incentives. However, at December 31, 2023, certain active projects for our Shipyard Division reflected a reduction to our estimated contract price for liquidated damages of $1.4 million.

Changes in Project Estimates

We determine the impact of changes in estimated margins on projects for a given period by calculating the amount of revenue recognized in the period that would have been recognized in a prior period had such estimated margins been forecasted in the prior period. The total impact of changes in estimated margins for a project as disclosed on a quarterly basis may be different from the applicable year-to-date impact due to the application of the POC method and the changing progress of the project at each period end. Such impacts may also be different when a project is commenced and completed within the applicable year-to-date period but spans multiple quarters.

For the three months ended March 31, 2024 and 2023, individual projects with significant changes in estimated margins did not have a material net impact on our operating results. The status of projects in backlog at March 31, 2024, which have previously experienced material changes in estimates, is as follows:

As discussed in our 2023 Financial Statements, as a result of design deficiencies, we experienced rework, construction and commissioning challenges on the two ferries, resulting in previous cost increases and liquidated damages, and the previous need to fabricate a new hull for the second vessel. Accordingly, during 2021, we submitted claims to our customer, and intend to pursue a lawsuit, to extend our project schedules and recover the cost impacts of the design deficiencies. The customer denied all liability. Our forecasts at March 31, 2024 do not reflect potential future benefits, if any, from the favorable resolution of the lawsuit and we can provide no assurance that we will be successful in recovering previously incurred costs.

Other Operating and Project Matters

During 2021, our operations were impacted by Hurricane Ida, which made landfall near Houma, Louisiana as a high-end Category 4 hurricane, causing debris and damage to our buildings and equipment at our Houma Facilities.

Fabrication Division Impacts – As of December 31, 2023, we had finalized all claims associated with our property and equipment insurance coverages, and at December 31, 2023, we had total insurance receivables on our Balance Sheet of $2.0 million. During the three months ended March 31, 2024 and 2023, we received insurance payments of $2.0 million and $0.7 million, respectively, from our insurance carriers associated with interruptions to our operations and damage to buildings and equipment. The classification of insurance proceeds within our Statement of Cash Flows is based on our use or intended use of the proceeds. Proceeds used or intended to be used for repairs that are not deemed to be capital in nature, and proceeds associated with interruptions to our operations, are reflected within operating activities. Proceeds used or intended to be used for repairs that are deemed capital in nature, or proceeds in excess of repair costs, are reflected within investing activities.

During the three months ended March 31, 2023, we recorded gains of $0.2 million (associated with our business interruption coverage) related to the net impact of insurance recoveries and costs associated with damage previously caused by Hurricane Ida. The gains are included in other (income) expense, net on our Statement of Operations and are reflected within our Fabrication Division.

Shipyard Division Impacts – In addition to damage to our Houma Facilities, the storm resulted in damage to one of our forty-vehicle ferry projects, the multi-purpose supply vessels (“MPSV(s)”) and associated equipment that were previously in our possession and subject to our previous MPSV Litigation, and certain bulkheads where the vessels were moored. During the three months ended March 31, 2023, we recorded charges of $0.1 million related to actual costs incurred. The charges are included in other (income) expense, net on our Statement of Operations and are reflected within our Shipyard Division. See Note 4 for further discussion of the resolution of our MPSV Litigation.
