(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 ($0.4) and ($3.1) million for the years ended December 31, 2013 and 2011, respectively.

(4)
Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $0.4 million and $0.5 million for the years ended December 31, 2013 and 2012, respectively.

(5)
Represents the elimination of inter-segment transactions and earnings (losses), net from the U.S. unconsolidated oil and gas joint venture, accounted for using the equity method until sold in December 2012, of ($289.2) million and $88.5 million for the years ended December 31, 2012 and 2011, respectively.

(6)
Adjusted income (loss) derived from operating activities is computed by subtracting the sum of direct costs, general and administrative expenses, depreciation and amortization and earnings (losses) from the U.S. oil and gas joint venture 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)
Represents the elimination of inter-segment transactions and unallocated corporate expenses, assets and capital expenditures.

(8)
