(1) All periods present the operating activities of our wholly owned oil and gas businesses, our previously held equity interests in oil and gas joint ventures in Canada and Colombia, aircraft logistics operations and construction services as discontinued operations.

(2) Includes our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software services. These services represent our other companies that are not aggregated into a reportable operating segment.

(3) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of ($2.5) million and $2.8 million for the three months ended March 31, 2014 and 2013, respectively.

(4) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $0.1 for each of the three months ended March 31, 2014 and 2013.

(5) Represents the elimination of inter-segment transactions and unallocated corporate expenses and assets.

(6) Adjusted income (loss) derived from operating activities is computed by subtracting the sum of direct costs, general and administrative expenses, depreciation and amortization from the sum of Operating revenues and Earnings (losses) from unconsolidated affiliates. These amounts should not be used as a substitute for the amounts reported in accordance with GAAP. However, management evaluates the performance of our business units and the consolidated company based on several criteria, including adjusted income (loss) derived from operating activities, because it believes that these financial measures accurately reflect our ongoing profitability. A reconciliation of this non-GAAP measure to income (loss) from continuing operations before income taxes, which is a GAAP measure, is provided in the above table.

(7) Includes $54.4 million and $56.9 million of investments in unconsolidated affiliates accounted for using the equity method as of March 31, 2014 and December 31, 2013, respectively.

(8) Reflects assets allocated to the line of business necessary to conduct its operations. Further allocation to individual operating segments of Completion & Production Services is not available.

(9) Includes $8.7 million and $7.4 million of investments in unconsolidated affiliates accounted for using the equity method as of March 31, 2014 and December 31, 2013, respectively.
