(1) Represents the elimination of inter-segment transactions.

(2) Adjusted operating income (loss) is computed by subtracting the sum of direct costs, general and administrative expenses, research and engineering expenses and depreciation and amortization from operating revenues. Management evaluates the performance of our operating segments using adjusted operating income (loss), which is a segment performance measure, because it believes that this financial measure reflects our ongoing profitability and performance. In addition, securities analysts and investors use this measure as one of the metrics on which they analyze our performance. A reconciliation to income (loss) from continuing operations before income taxes is provided in the above table.

Represents the elimination of inter-segment transactions and unallocated corporate expenses, assets and capital expenditures.
