Schedule of Segment Operating Information by Segment

Operating Information by Segment

The accounting policies for the three reportable segments are consistently applied, as described in Note 1, Summary of Significant Accounting Policies. The Company's chief operating decision maker (the "CODM") is the Company's Chairman and Chief Executive Officer. The CODM uses segment operating income/(loss) as the profit measure to evaluate segment performance and allocate resources across segments. Corporate unallocated expenses, interest income, interest expense, facility fees and debt-related income (expense) and defined benefit pension income (expense) are centrally managed costs and are, therefore, excluded from this profit measure to provide better understanding of the Company's segment operating results. The CODM considers variances of actual performance to the Company's annual operating plan and periodic forecasts when making decisions.

The following tables include information about the Company's revenues and operating income (loss) by reporting segment, along with significant segment expenses and other segment information, for the years ended December 31, 2024, 2023 and 2022:
