Summary of Significant Accounting Policies |
Interim Financial Information | Interim Financial Information The accompanying unaudited condensed consolidated financial statements of Nabors have been prepared in conformity with generally accepted accounting principles 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 together with our annual report on Form 10-K for the year ended December 31, 2016 (“2016 Annual Report”). In management’s opinion, the unaudited condensed consolidated financial statements contain all adjustments necessary to state fairly our financial position as of September 30, 2017 and the results of operations, comprehensive income (loss), cash flows and changes in equity for the periods presented herein. Interim results for the nine months ended September 30, 2017 may not be indicative of results that will be realized for the full year ending December 31, 2017.
Principles of Consolidation | Principles of Consolidation Our condensed 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. During 2016, we entered into an agreement with Saudi Arabian Development Company, a wholly-owned subsidiary of Saudi Arabian Oil Company (“Saudi Aramco”), to form a new joint venture, Saudi Aramco Nabors Drilling (“SANAD”), to own, manage and operate onshore drilling rigs in The Kingdom of Saudi Arabia. SANAD, which is equally owned by Saudi Aramco and Nabors, is expected to commence operations during the fourth quarter of 2017. In May 2017, Nabors and Saudi Aramco each contributed $20 million in cash for formation of the joint venture. We have consolidated this joint venture which, as of September 30, 2017, is limited to the $40 million of cash mentioned above to be used exclusively by the joint venture to fund future operations. 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 condensed consolidated statements of income (loss). The investments in these entities are included in investment in other long-term assets in our condensed consolidated balance sheets. We historically recorded our share of the net income (loss) of our equity method investment in C&J Energy Services, Ltd. (“CJES”) on a one-quarter lag, as we were not able to obtain the financial information of CJES on a timely basis. During the third quarter of 2016, CJES filed for bankruptcy, at which time we ceased accounting for our investment in CJES as an equity method investment. See Note 4 — Investments in Unconsolidated Affiliates.
Revenue Recognition | Revenue Recognition We recognize revenues and costs on daywork contracts daily as the work progresses. For certain contracts, we receive lump-sum payments for the mobilization of rigs and other drilling equipment. We defer revenue related to mobilization periods and recognize the revenue over the term of the related drilling contract. We also defer recognition of revenue on amounts received from customers for prepayment of services until those services are provided. At September 30, 2017 and December 31, 2016, our deferred revenues classified as accrued liabilities were $241.8 million and $255.6 million, respectively. At September 30, 2017 and December 31, 2016, our deferred revenues classified as other long-term liabilities were $167.8 million and $321.0 million, respectively. Costs incurred related to a mobilization period for which a contract is secured are deferred and recognized over the term of the related drilling contract. Costs incurred to relocate rigs and other drilling equipment to areas in which a contract has not been secured are expensed as incurred. At September 30, 2017 and December 31, 2016, our deferred expenses classified as other current assets were $66.6 million and $63.4 million, respectively. At September 30, 2017 and December 31, 2016, our deferred expenses classified as other long-term assets were $41.7 million and $69.5 million, respectively. We recognize revenue for top drives and instrumentation systems we manufacture when the earnings process is complete. This generally occurs when products have been shipped, title and risk of loss have been transferred, collectability is probable, and pricing is fixed and determinable. We recognize, as operating revenue, proceeds from business interruption insurance claims in the period that the applicable proof of loss documentation is received. Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in other, net in the period that the applicable proof of loss documentation is received. Proceeds from casualty insurance settlements that are expected to be less than the carrying value of damaged assets are recognized at the time the loss is incurred and recorded in other, net. We recognize reimbursements received for out-of-pocket expenses incurred as revenues and account for out-of-pocket expenses as direct costs.
Inventory, net | Inventory, net Inventory is stated at the lower of cost or net realizable value. 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:
|  | September 30, |  | December 31, |
|  | 2017 |  | 2016 |
|  | (In thousands) |
Raw materials |  | $ | 89,127 |  | $ | 84,431 |
Work-in-progress |  |  | 15,630 |  |  | 1,204 |
Finished goods |  |  | 14,293 |  |  | 17,960 |
|  | $ | 119,050 |  | $ | 103,595 |
Property, Plant and Equipment | Property, Plant and Equipment We review our assets for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the estimated undiscounted future cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to the extent the carrying amount of the long-lived asset exceeds its estimated fair value. Management considers a number of factors such as estimated future cash flows from the assets, appraisals and current market value analysis in determining fair value. The determination of future cash flows requires the estimation of utilization, dayrates, operating margins, sustaining capital and remaining economic life. Such estimates can change based on market conditions, technological advances in the industry or changes in regulations governing the industry. For an asset classified as held for sale, we consider the asset impaired when its carrying amount exceeds fair value less its cost to sell. Fair value is determined in the same manner as an impaired long-lived asset that is held and used. Significant and unanticipated changes to the assumptions could result in future impairments. A significantly prolonged period of lower oil and natural gas prices could adversely affect the demand for and prices of our services. As such, we will continue to assess our asset fleet for triggering events, particularly our legacy and undersized rigs. Should we experience weakening in the market for a prolonged period for any specific rig class, this could result in future impairment charges or retirements of assets. As the determination of whether impairment charges should be recorded on our long-lived assets is subject to significant management judgment, and an impairment of these assets could result in a material charge on our condensed consolidated statements of income (loss), management believes that accounting estimates related to impairment of long-lived assets are critical.
Goodwill | 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. Due to the adoption of Accounting Standards Update (“ASU”) No. 2017-04, effective January 1, 2017, we no longer determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. We will continue to perform our qualitative analysis as well as step one of the impairment test which compares the estimated fair value of the reporting unit to its carrying amount. If the carrying amount exceeds the fair value, an impairment charge will be recognized in an amount equal to the excess; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For our goodwill tests prior to adoption of the new standard, we initially assessed 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 compared the estimated fair value of the reporting unit to its carrying amount. If the carrying amount exceeded the fair value, a second step was required to measure the goodwill impairment loss. The second step compared the implied fair value of the reporting unit’s goodwill to its carrying amount. If the carrying amount exceeded the implied fair value, an impairment loss was 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 triggering events 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 of assets and additional transactions in the oil and gas industry. Another factor in determining whether a triggering event 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. Based on our annual review during the second quarter of 2017, we did not record a goodwill impairment.
Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-07, Investments—Equity Method and Joint Ventures, to simplify the transition to the equity method of accounting. This standard eliminates the requirement to retroactively adopt the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. Instead, the equity method investor should add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment qualifies for the equity method of accounting. This guidance is effective for public companies for fiscal years beginning after December 15, 2016. The adoption of this guidance did not have an impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation, to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. This guidance is effective for public companies for fiscal years beginning after December 15, 2016. We adopted this guidance on a prospective basis effective January 1, 2017. The impact of adoption was a decrease in deferred tax liabilities of $7.1 million and an increase in retained earnings of $7.1 million related to excess tax benefits on prior awards. Additionally, we elected to account for forfeitures as they occur. The impact of this election resulted in an increase in capital in excess of par and a corresponding decrease in retained earnings of $1.9 million. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step 2 of the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under this new standard, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and then recognize an impairment charge, as necessary, for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. This guidance is effective for fiscal years beginning after December 15, 2019. We have elected to early adopt this guidance on a prospective basis for our annual goodwill impairment test performed subsequent to January 1, 2017. The adoption of this standard did not have an impact on our consolidated financial statements.
Recent Accounting Pronouncements Not Yet Adopted | Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, relating to the revenue recognition from contracts with customers that creates a common revenue standard for GAAP and IFRS. The core principle will require recognition of revenue to represent the transfer of promised goods or services to customers in an amount that reflects the consideration, including costs incurred, to which the entity expects to be entitled in exchange for those goods or services. The standard will also require significantly expanded disclosures containing qualitative and quantitative information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB approved a one year deferral of this standard, with a new effective date for fiscal years beginning after December 15, 2017. Throughout 2017 we have taken many steps towards quantifying the impact of the new standard on our contracts. We, along with our third party consultants, have identified and reviewed our revenue streams, identified a subset of contracts to represent these revenue streams and performed a detailed analysis of such contracts. As part of this analysis, we identified specific areas impacted under the new standard. We have finalized our bucketing of contracts and expanded our sample of contracts for review in order to evaluate, document and quantify the consolidated impact of adopting the standard. We expect to apply the modified retrospective approach during the first quarter of 2018. However, we continue to evaluate the impact of the standard on our accounting policies, internal controls and consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall, relating to the recognition and measurement of financial assets and liabilities. This standard enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. We are currently evaluating the impact this will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, relating to leases to increase transparency and comparability among companies. This standard requires that all leases with an initial term greater than one year be recorded on the balance sheet as an asset and a lease liability. Additionally, this standard will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. This guidance is effective for public companies for fiscal years beginning after December 15, 2018. Early application is permitted. This standard requires an entity to separate lease components from nonlease components within a contract. While the lease components would be accounted for under ASU No. 2016-02, nonlease components would be accounted for under ASU No. 2014-09. We have determined that under the new standard, our drilling contracts contain a lease component and therefore we will be required to separately recognize revenues associated with the lease and services components. Therefore, we are evaluating ASU No. 2016-02 concurrently with the provisions of ASU No. 2014-09 and the impact this will have on our consolidated financial statements. We expect to adopt this guidance as of the effective date. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows, to reduce the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. We are currently evaluating the impact this will have on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes, which improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. We are currently evaluating the impact this will have on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, to provide guidance on the classification of restricted cash in the statement of cash flows. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. The amendments in the ASU should be adopted on a retrospective basis. We are currently evaluating the impact this will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. The standard provides a test to determine whether a set of assets and activities acquired is a business. When substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the set is not a business. Under the updated guidance, an acquisition of a single property will likely be treated as an asset acquisition as opposed to a business combination and associated transaction costs will be capitalized rather than expensed as incurred. Additionally, assets acquired, liabilities assumed, and any noncontrolling interest will be measured at their relative fair values. We do not expect the adoption of this standard to have an impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation, to reduce diversity in practice and provide clarity regarding existing guidance in ASC 718, “Stock Compensation”. The standard provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after the modification. This guidance is effective for public companies for fiscal years beginning after December 15, 2017. Early application is permitted. We are currently evaluating the impact that this will have on our consolidated financial statements.
