PKD Parker Drilling Co.

Management Discussion

• Our business is comprised of two business lines: (1) rental tools services and (2) drilling services. We report our rental tools services business as two reportable segments: (1) U.S. rental tools and (2) International rental tools. We report our drilling services business as two reportable segments: (1) U.S. (lower 48) drilling and (2) International & Alaska drilling. We eliminate inter-segment revenues and expenses.
• We analyze financial results for each of our reportable segments. The reportable segments presented are consistent with our reportable segments discussed in our consolidated condensed financial statements. See Note 12 - Reportable Segments in Item 1. Financial Statements for further discussion. We monitor our reporting segments based on several criteria, including operating gross margin and operating gross margin excluding depreciation and amortization. Operating gross margin excluding depreciation and amortization is computed as revenues less direct operating expenses, and excludes depreciation and amortization expense, where applicable. Operating gross margin percentages are computed as operating gross margin as a percent of revenues. The operating gross margin excluding depreciation and amortization amounts and percentages should not be used as a substitute for those amounts reported under accounting principles generally accepted in the United States (“U.S. GAAP”), but should be viewed in addition to the Company’s reported results prepared in accordance with U.S. GAAP. Management believes this information provides valuable insight into the information management considers important in managing the business.
