ITEM 6. SELECTED FINANCIAL DATA

     The following table presents selected historical consolidated financial data derived from the audited financial statements of Parker Drilling for each of the five years in the period ended December 31, 2003. In 2003, our board of directors approved a plan to sell our non-core assets, which, as of December 31, 2003, includes our Latin America assets, consisting of 16 land rigs and related inventory and spare parts, and our U.S. offshore assets, consisting of six jackup and four platform rigs. The two operations that constitute this plan of disposition meet the requirements of discontinued operations under the provisions of SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” Accordingly, our consolidated financial statements for each of the five years in the period ended December 31, 2003 have been reclassified to present our Latin America operations and our U.S. jackup and platform drilling operations as discontinued operations and net gain on disposition of assets for continuing operations have been reclassified as part of total operating income. The financial data for the year ended December 31, 2000 has also been reclassified to reflect the adoption of SFAS No. 145, “Rescission of FASB Statements No. 4, No. 44, and No. 64, Amendment of FASB Statement No. 13, and Technical Corrections,” which resulted in the reclassification of the extraordinary gain on early extinguishment of debt to other income and the related deferred taxes to income tax expense.

(1) During the first quarter of 2003, the Company determined that pursuant to the provisions of EITF No. 01-14, “Income Statement Characterization of Reimbursements Received for Out-of-Pocket Expenses Incurred,” amounts received as reimbursements should have been reported as revenues, with the corresponding amounts reported as operating expenses. In prior years, the Company netted the reimbursement with the cost in the statement of operations. Accordingly, the Company has revised its previously issued statement of operations to reflect this new presentation. The effect of making this change was an increase in both total drilling and rental revenues and total drilling and rental operating expenses for continuing operations of $32.6 million, $37.6 million, $20.8 million and $8.1 million for the years ended December 31, 2002, 2001, 2000 and 1999, respectively, and $4.9 million, $7.1 million, $9.7 million and $10.4 million for discontinued operations for the years ended December 31, 2002, 2001, 2000 and 1999, respectively. This revision has no effect on total operating income, net income, cash flows or any balance sheet amount presented.
