Note 2 Summary of Significant Accounting Policies

Interim Financial Information

The unaudited consolidated financial statements of Nabors are prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. Therefore, these financial statements should be read along with our annual report on Form 10-K for the year ended December 31, 2013 (“2013 Annual Report”). In management’s opinion, the consolidated financial statements contain all adjustments necessary to present fairly our financial position as of March 31, 2014, as well as the results of our operations, other comprehensive income, our cash flows and changes in equity for the three months ended March 31, 2014 and 2013, in accordance with GAAP. Interim results for the three months ended March 31, 2014 may not be indicative of results that will be realized for the full year ending December 31, 2014.

Our independent registered public accounting firm has reviewed and issued a report on these consolidated interim financial statements in accordance with standards established by the Public Company Accounting Oversight Board. Pursuant to Rule 436(c) under the Securities Act of 1933, as amended (the “Securities Act”), this report should not be considered a part of any registration statement prepared or certified within the meanings of Sections 7 and 11 of such Act.

Prior Period Revision

During the first quarter of 2014, we determined that we had incorrectly applied certain aspects of ASC 830 - Foreign Currency Matters with respect to the recording of foreign currency gains or losses on certain intercompany transactions. GAAP requires the recognition of foreign currency gains or losses on U.S. dollar denominated intercompany balances of our subsidiaries that have a functional currency other than the U.S. dollar. The primary years impacted were 2002 and 2009, which is the period over which a series of intercompany loans were outstanding between our Canadian subsidiary, whose functional currency is the Canadian dollar, and other subsidiaries whose functional currencies are the U.S. dollar.

The net effect understated net income for periods before 2009 by approximately $91.5 million, due to foreign currency gains that should have been recorded through net income, rather than through Cumulative Translation Adjustments (a component of Accumulated Other Comprehensive Income). The correction of this error resulted in a revision to increase the beginning Retained Earnings at January 1, 2010 by approximately $91.5 million with the offset being a decrease to Accumulated Other Comprehensive Income, both of which are components of Shareholders’ Equity. There was no other material impact to our assets, liabilities, cash flows or profit and loss for any periods presented. We do not consider this revision material to any period.

Principles of Consolidation

Our consolidated financial statements include the accounts of Nabors, as well as all majority owned and non-majority owned subsidiaries required to be consolidated under GAAP. All significant intercompany accounts and transactions are eliminated in consolidation.

Investments in operating entities where we have the ability to exert significant influence, but where we do not control operating and financial policies, are accounted for using the equity method. Our share of the net income (loss) of these entities is recorded as earnings (losses) from unconsolidated affiliates in our consolidated statements of income (loss). The investments in these entities are included in investment in unconsolidated affiliates in our consolidated balance sheets.

Inventory

Inventory is stated at the lower of cost or market. Cost is determined using the first-in, first-out or weighted-average cost methods and includes the cost of materials, labor and manufacturing overhead. Inventory included the following:

Goodwill

We review goodwill for impairment annually during the second quarter of each fiscal year or more frequently if events or changes in circumstances indicate that the carrying amount of such goodwill and intangible assets exceed their fair value. We initially assess goodwill for impairment based on qualitative factors to determine whether to perform the two-step annual goodwill impairment test, a Level 3 fair value measurement. After our qualitative assessment, step one of the impairment test compares the estimated fair value of the reporting unit to its carrying amount. If the carrying amount exceeds the fair value, a second step is required to measure the goodwill impairment loss. The second step compares the implied fair value of the reporting unit’s goodwill to its carrying amount. If the carrying amount exceeds the implied fair value, an impairment loss is recognized in an amount equal to the excess.

Our estimated fair values of our reporting units incorporate judgment and the use of estimates by management. Potential factors requiring assessment include a further or sustained decline in our stock price, declines in oil and natural gas prices, a variance in results of operations from forecasts, a change in operating strategy for particular assets and additional transactions in the oil and gas industry. Another factor in determining whether impairment has occurred is the relationship between our market capitalization and our book value. As part of our annual review, we compare the sum of our reporting units’ estimated fair value, which includes the estimated fair value of non-operating assets and liabilities, less debt, to our market capitalization and assess the reasonableness of our estimated fair value. Any of the above-mentioned factors may cause us to re-evaluate goodwill during any quarter throughout the year.
