NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 Nature of Operations

Unless the context requires otherwise, references in this report to “we,” “us,” “our,” “the Company,” or “Nabors” mean Nabors Industries Ltd., together with our subsidiaries where the context requires.

We own and operate the world’s largest land-based drilling rig fleet and are a leading provider of offshore platform drilling rigs in the United States and multiple international markets. We also provide advanced wellbore placement services, drilling software and performance tools, drilling equipment and innovative technologies throughout the world’s most significant oil and gas markets.

As a global provider of drilling and drilling-related services for land-based and offshore oil and natural gas wells, our fleet of rigs and drilling-related equipment as of June 30, 2017 included:

· 405 actively marketed rigs for land-based drilling operations in the United States, Canada and approximately 20 other countries throughout the world; and

· 41 actively marketed rigs for offshore drilling operations in the United States and multiple international markets.

Our business consists of four reportable operating segments: U.S., Canada, International and Rig Services.

Note 2 Summary of Significant Accounting Policies

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 June 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 six months ended June 30, 2017 may not be indicative of results that will be realized for the full year ending December 31, 2017.

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 to own, manage and operate onshore drilling rigs in The Kingdom of Saudi Arabia. The joint venture, which is equally owned by Saudi Aramco and Nabors, is expected to commence operations in the second half 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 June 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

8

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 3 — Investments in Unconsolidated Affiliates.

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 June 30, 2017 and December 31, 2016, our deferred revenues classified as accrued liabilities were $278.3 million and $255.6 million, respectively. At June 30, 2017 and December 31, 2016, our deferred revenues classified as other long-term liabilities were $191.8 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 June 30, 2017 and December 31, 2016, our deferred expenses classified as other current assets were $69.4 million and $63.4 million, respectively. At June 30, 2017 and December 31, 2016, our deferred expenses classified as other long-term assets were $48.2 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 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:

	June 30,		December 31,
	2017		2016

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

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.

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

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. 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 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 now expanded our population and are reviewing our contracts in order to quantify the consolidated impact of such changes. At this time, we expect to apply the modified retrospective approach during the first quarter of 2018. However, we are still evaluating the requirements to determine the impact of the adoption on our 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

11

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. 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 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.

Note 3 Investments in Unconsolidated Affiliates

On March 24, 2015, we completed the merger of our Completion & Production Services business with C&J Energy Services, Inc.. We received total consideration comprised of approximately $693.5 million in cash ($650.0 million after settlement of working capital requirements) and approximately 62.5 million common shares in the combined company, CJES, representing approximately 53% of the outstanding and issued common shares of CJES as of the closing date. We recognized our share of the net income (loss) of CJES, which was a loss of $54.8 million and $221.9 million, respectively, for the three and six months ended June 30, 2016, and is reflected in earnings (losses) from unconsolidated affiliates in our condensed consolidated statements of income (loss). Additionally, we recognized other-than-temporary impairment charges of $39.0 million and $192.4 million, respectively, during the three and six months ended June 30, 2016, which is reflected in other, net in our condensed consolidated statements of income (loss). During the third quarter of 2016, CJES commenced voluntarily cases under chapter 11 of the U.S. Bankruptcy code. As such, we ceased accounting for our investment in CJES as an equity method investment. In January 2017, CJES emerged from bankruptcy and as part of the settlement we received warrants to acquire the common equity in the reorganized CJES. 

Note 4 Fair Value Measurements

Our financial assets and liabilities that are accounted for at fair value on a recurring basis as of June 30, 2017 consist of available-for-sale equity and debt securities. Our debt securities could transfer into or out of a Level 1 or 2 measure depending on the availability of independent and current pricing at the end of each quarter. During the three and six months ended June 30, 2017, there were no transfers of our financial assets between Level 1 and Level 2 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The majority of our short-term investments are categorized as Level 1 and had a fair value of $24.9 million as of June 30, 2017.  Additionally, we report our investment in the CJES warrants at fair value based on

12

quoted market prices or prices quoted from third-party financial institutions. This measure is categorized as Level 2 and had a fair value of $10.6 million as of June 30, 2017.

Nonrecurring Fair Value Measurements

We applied fair value measurements to our nonfinancial assets and liabilities measured on a nonrecurring basis, which consist of measurements primarily to assets held for sale, goodwill, equity method investments, intangible assets and other long-lived assets, assets acquired and liabilities assumed in a business combination and our pipeline contractual commitment. Based upon our review of the fair value hierarchy, the inputs used in these fair value measurements were considered Level 3 inputs.

Fair Value of Financial Instruments

We estimate the fair value of our financial instruments in accordance with GAAP. The fair value of our long-term debt, revolving credit facility and commercial paper is estimated based on quoted market prices or prices quoted from third-party financial institutions. The fair value of our debt instruments is determined using Level 2 measurements. The carrying and fair values of these liabilities were as follows:

	June 30, 2017				December 31, 2016
	Carrying		Fair		Carrying		Fair
	Value		Value		Value		Value

(1) The 6.15% senior notes due February 2018 have been classified as long-term because we have the ability and intent to repay this obligation utilizing our revolving credit facility.

During the six months ended June 30, 2017, we repurchased or redeemed $363.2 million aggregate principal amount of our 6.15% senior notes due February 2018 for approximately $382.5 million in cash, reflecting principal and approximately $5.6 million of accrued and unpaid interest. The difference represents the premiums paid in connection with these repurchases or redemptions and is included in other, net in our condensed consolidated statement of income (loss) for the six months ended June 30, 2017.

0.75% Senior Exchangeable Notes Due January 2024

In January 2017, Nabors Industries, Inc. (“Nabors Delaware”), a wholly owned subsidiary of Nabors, issued $575 million in aggregate principal amount of 0.75% exchangeable senior unsecured notes due 2024, which are fully and unconditionally guaranteed by Nabors. The notes bear interest at a rate of 0.75% per year payable semiannually on January 15 and July 15 of each year, beginning on July 15, 2017. The exchangeable notes are bifurcated for accounting purposes into debt and equity components of $411.2 million and $163.8 million, respectively, based on the relative fair value. Debt issuance costs of $9.6 million and equity issuance costs of $3.9 million were capitalized in connection with the issuance of these notes in long-term debt and netted against the proceeds allocated to the equity component, respectively, in our condensed consolidated balance sheet. The debt issuance costs are being amortized through January 2024.

The exchangeable notes are exchangeable, under certain conditions, at an initial exchange rate of 39.75 common shares of Nabors per $1,000 principal amount of exchangeable notes (equivalent to an initial exchange price of approximately $25.16 per common share). Upon any exchange, Nabors Delaware will settle its exchange obligation in cash, common shares of Nabors, or a combination of cash and common shares, at our election.

14

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions which are expected to reduce potential dilution to common shares and/or offset potential cash payments required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap representing a price per share of $31.45, an approximately 75.0% premium over our share price of $17.97 as of the date of the transaction.

The net proceeds from the offering of the exchangeable notes were used to prepay the remaining balance of our unsecured term loan originally scheduled to mature in 2020, as well as to pay the cost of the capped call transactions. The remaining net proceeds from the offering were allocated for general corporate purposes, including to repurchase or repay other indebtedness.

Commercial Paper Program

As of June 30, 2017, we had approximately $172.0 million of commercial paper outstanding. The weighted average interest rate on borrowings at June 30, 2017 was 1.63%. Our commercial paper borrowings are classified as long-term debt because the borrowings are fully supported by availability under our revolving credit facility, which matures as currently structured in July 2020, more than one year from now.

Revolving Credit Facility

As of June 30, 2017, we had $100.0 million outstanding under our $2.25 billion revolving credit facility, which matures in July 2020. The weighted average interest rate on borrowings at June 30, 2017 was 2.52%. The revolving credit facility contains various covenants and restrictive provisions that limit our ability to incur additional indebtedness, make investments or loans and create liens and require us to maintain a net funded indebtedness to total capitalization ratio, as defined in the agreement. Availability under the revolving credit facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. We were in compliance with all covenants under the agreement at June 30, 2017. If we fail to perform our obligations under the covenants, the revolving credit commitment could be terminated, and any outstanding borrowings under the facility could be declared immediately due and payable.

Term Loan Facility

On September 29, 2015, Nabors Delaware entered into a new five-year unsecured term loan facility for $325.0 million, which is fully and unconditionally guaranteed by us. The term loan facility contained a mandatory prepayment of $162.5 million due in September 2018, which was repaid in December 2016 utilizing a portion of the proceeds received in connection with the 5.50% senior notes offering. In January 2017, we repaid the remaining $162.5 million term loan utilizing the proceeds received in connection with the 0.75% senior exchangeable notes and the facility was terminated.

Note 6 Common Shares

During the six months ended June 30, 2016, we repurchased 0.3 million of our common shares in the open market for $1.7 million, all of which are held in treasury.

On April 21, 2017, a cash dividend of $0.06 per share was declared for shareholders of record on June 14, 2017. The dividend was paid on July 5, 2017 in the amount of $17.1 million and was charged to retained earnings in our condensed consolidated statement of changes in equity for the six months ended June 30, 2017.

Note 7 Commitments and Contingencies

Contingencies

Income Tax

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our

15

subsidiaries in certain countries, if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could change substantially.

We have received an assessment from a tax authority in Latin America in connection with a 2007 income tax return. The assessment relates to the denial of depreciation expense deductions related to drilling rigs. Similar deductions were taken for tax year 2009. Although Nabors and its tax advisors believe these deductions are appropriate and intend to continue to defend our position, we have recorded a partial reserve to account for this contingency. If we ultimately do not prevail, we estimate that we would be required to recognize additional tax expense in the range of $3 million to $8 million.  

Self-Insurance

We estimate the level of our liability related to insurance and record reserves for these amounts in our condensed consolidated financial statements. Our estimates are based on the facts and circumstances specific to existing claims and our past experience with similar claims. These loss estimates and accruals recorded in our financial statements for claims have historically been reasonable in light of the actual amount of claims paid and are actuarially supported. Although we believe our insurance coverage and reserve estimates are reasonable, a significant accident or other event that is not fully covered by insurance or contractual indemnity could occur and could materially affect our financial position and results of operations for a particular period.

We self-insure for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Some of our workers’ compensation, employers’ liability and marine employers’ liability claims are subject to a $3.0 million per-occurrence deductible; additionally, some of our automobile liability claims are subject to a $2.5 million deductible. General liability claims remain subject to a $5.0 million per-occurrence deductible. Our policies were renewed effective April 1, 2017 and remain subject to these same deductibles.

In addition, we are subject to a $5.0 million deductible for land rigs and for offshore rigs. This applies to all kinds of risks of physical damage except for named windstorms in the U.S. Gulf of Mexico for which we are self-insured.

Litigation

Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. For matters where an unfavorable outcome is reasonably possible and significant, we disclose the nature of the matter and a range of potential exposure, unless an estimate cannot be made at the time of disclosure. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.

In March 2011, the Court of Ouargla entered a judgment of approximately $26.2 million (at June 30, 2017 exchange rates) against us relating to alleged violations of Algeria’s foreign currency exchange controls, which require that goods and services provided locally be invoiced and paid in local currency. The case relates to certain foreign currency payments made to us by CEPSA, a Spanish operator, for wells drilled in 2006. Approximately $7.5 million of the total contract amount was paid offshore in foreign currency, and approximately $3.2 million was paid in local currency. The judgment includes fines and penalties of approximately four times the amount at issue. We have appealed the ruling based on our understanding that the law in question applies only to resident entities incorporated under Algerian law. An intermediate court of appeals upheld the lower court’s ruling, and we appealed the matter to the Supreme Court. On September 25, 2014, the Supreme Court overturned the verdict against us, and the case was reheard by the Ouargla Court of Appeals on March 22, 2015 in light of the Supreme Court’s opinion. On March 29, 2015, the Ouargla Court of Appeals reinstated the initial judgment against us. We have appealed this decision again to the Supreme Court. While our payments were consistent with our historical operations in the country, and, we believe, those of other multinational

16

corporations there, as well as interpretations of the law by the Central Bank of Algeria, the ultimate resolution of this matter could result in a loss of up to $18.2 million in excess of amounts accrued.

In March 2012, Nabors Global Holdings II Limited (“NGH2L”) signed an agreement with ERG Resources, LLC (“ERG”) relating to the sale of all of the Class A shares of NGH2L’s wholly owned subsidiary, Ramshorn International Limited, an oil and gas exploration company (“Ramshorn”) (“the ERG Agreement”). When ERG failed to meet its closing obligations, NGH2L terminated the transaction on March 19, 2012 and, as contemplated in the agreement, retained ERG’s $3.0 million escrow deposit. ERG filed suit the following day in the 61st Judicial District Court of Harris County, Texas, in a case styled ERG Resources, LLC v. Nabors Global Holdings II Limited, Ramshorn International Limited, and Parex Resources, Inc.; Cause No. 2012 16446, seeking injunctive relief to halt any sale of the shares to a third party, specifically naming as defendant Parex Resources, Inc. (“Parex”). The lawsuit also sought monetary damages of up to $750.0 million based on an alleged breach of contract by NGH2L and alleged tortious interference with contractual relations by Parex. We successfully defeated ERG’s effort to obtain a temporary restraining order from the Texas court on March 20, 2012 and completed the sale of Ramshorn’s Class A shares to a Parex affiliate in April 2012, which mooted ERG’s application for a temporary injunction. The defendants made numerous jurisdictional challenges on appeal, and on April 30, 2015, ERG filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code. Accordingly, the civil actions are currently subject to the bankruptcy stay and ERG’s claims in the lawsuit are assets of the estate. The lawsuit was stayed, pending further court actions, including appeals of the jurisdictional decisions. On June 17, 2016, the Texas Supreme Court issued its opinion on the jurisdictional appeal holding that jurisdiction exists in Texas for Ramshorn, but not for Parex Bermuda or Parex Canada. ERG retains its causes of action for monetary damages, but we believe the claims are foreclosed by the terms of the ERG Agreement and are without factual or legal merit. On December 28, 2016, the District Court granted Nabors’ Motion for Partial Summary Judgment to Enforce Exclusive Remedies Clause, holding that ERG’s potential recovery in the action may not exceed $4.5 million in accordance with the terms of the ERG Agreement. The plaintiffs challenged this ruling and Parex was poised to enter into a settlement agreement, over the objection of Nabors, whereby ERG would release Parex from all claims in exchange for a $15 million cash payment from Parex. The Parex settlement changed the dynamics of the ongoing litigation between Nabors and ERG, with all signs indicating that the bankrupt ERG intended to use the cash influx from Parex to pursue a low‐risk but potentially high‐reward strategy by continuing with its claim against Nabors. With this development Nabors re‐evaluated its options, noting that however remote, a negative outcome at trial had the potential for a significantly adverse financial impact. As a result, in order to mitigate expenses associated with what was proving to be lengthy and potentially costly litigation, Nabors has agreed to a settlement in which ERG will release NGH2L from all claims in exchange for a payment of $20 million by NGH2L. This settlement resulted in a pre-tax charge of $16.5 million, which is included in net income (loss) from discontinued operations within our condensed consolidated statement of income for the three and six months ended June 30, 2017. The parties are working on documenting the settlement, which will not include an admission of wrongdoing by NGH2L. It is anticipated that the settlement, including the payment from NGH2L, will occur during the third quarter of 2017.

Off-Balance Sheet Arrangements (Including Guarantees)

We are a party to some transactions, agreements or other contractual arrangements defined as “off-balance sheet arrangements” that could have a material future effect on our financial position, results of operations, liquidity and capital resources. The most significant of these off-balance sheet arrangements involve agreements and obligations under which we provide financial or performance assurance to third parties. Certain of these agreements serve as guarantees, including standby letters of credit issued on behalf of insurance carriers in conjunction with our workers’ compensation insurance program and other financial surety instruments such as bonds. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by Nabors to our share transfer agent and our insurance carriers. We are not able to estimate the potential future maximum payments that might be due under our indemnification guarantees.

Management believes the likelihood that we would be required to perform or otherwise incur any material losses associated with any of these guarantees is remote. The following table summarizes the total maximum amount of financial guarantees issued by Nabors:

	Maximum Amount
	2017		2018	2019	Thereafter	Total

Note 8 Earnings (Losses) Per Share

ASC 260, Earnings per Share, requires companies to treat unvested share-based payment awards that have nonforfeitable rights to dividends or dividend equivalents as a separate class of securities in calculating earnings (losses) per share. We have granted and expect to continue to grant to employees restricted stock grants that contain nonforfeitable rights to dividends. Such grants are considered participating securities under ASC 260. As such, we are required to include these grants in the calculation of our basic earnings (losses) per share and calculate basic earnings (losses) per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings.

Basic earnings (losses) per share is computed utilizing the two-class method and is calculated based on the weighted-average number of common shares outstanding during the periods presented.

Diluted earnings (losses) per share is computed using the weighted-average number of common and common equivalent shares outstanding during the periods utilizing the two-class method for stock options and unvested restricted stock. Shares issuable upon exchange of the $575 million 0.75% exchangeable notes are not included in the calculation of diluted earnings (losses) per share unless the exchange value of the notes exceeds their principal amount at the end of the relevant reporting period, in which case the notes will be accounted for as if the number of common shares that would be necessary to settle the excess are issued. Such shares are only included in the calculation of the weighted-average number of shares outstanding in our diluted earnings (losses) per share calculation, when the price of our shares exceeds $25.16 on the last trading day of the quarter, which did not occur during the six months ended June 30, 2017.

For all periods presented, the computation of diluted earnings (losses) per share excludes outstanding stock options with exercise prices greater than the average market price of Nabors’ common shares, because their inclusion would be anti-dilutive and because they are not considered participating securities. For periods in which we experience a net loss from continuing operations, all potential common shares have been excluded from the calculation of weighted-average shares outstanding, because their inclusion would be anti-dilutive. The average number of options that were excluded from diluted earnings (losses) per share that would potentially dilute earnings per share in the future were as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2017		2016		2017		2016
Potentially dilutive securities excluded as anti-dilutive		4,469,382		5,379,424		4,558,594		5,397,068

In any period during which the average market price of Nabors’ common shares exceeds the exercise prices of these stock options, such stock options will be included in our diluted earnings (losses) per share computation using the if-converted method of accounting. Restricted stock is included in our basic and diluted earnings (losses) per share computation using the two-class method of accounting in all periods because such stock is considered participating securities.

Note 10 Assets Held for Sale and Discontinued Operations

Assets Held for Sale

Assets held for sale as of June 30, 2017 and December 31, 2016 was $78.4 million and $76.7 million, respectively. These assets consisted primarily of our oil and gas holdings which are mainly in the Horn River basin in western Canada of $67.2 million and $65.0 million, respectively, as of the periods noted above and the operating results have been reflected in discontinued operations. The remainder represents assets that meet the criteria to be classified as assets held for sale, but do not represent a disposal of a component of an entity or a group of components of an entity representing a strategic shift that has or will have a major effect on the entity's operations and financial results.

The carrying value of our assets held for sale represents the lower of carrying value or fair value less costs to sell. We continue to market these properties at prices that are reasonable compared to current fair value.

Our liabilities held for sale as of June 30, 2017 includes a $20.0 million reserve in connection with the settlement of litigation associated with our previously owned Ramshorn International properties.

We have contracts with pipeline companies to pay specified fees based on committed volumes for gas transport and processing associated with these properties held for sale. At June 30, 2017, our undiscounted contractual commitments for these contracts approximated $14.3 million and we had liabilities of $10.7 million, $5.8 million of which were classified as current and were included in accrued liabilities. At December 31, 2016, our undiscounted contractual commitments for these contracts approximated $17.2 million and we had liabilities of $12.5 million, $5.5 million of which were classified as current and were included in accrued liabilities.

The amounts at each balance sheet date represented our best estimate of the fair value of the excess capacity of the pipeline commitments calculated using a discounted cash flow model, when considering our disposal plan, current production levels, natural gas prices and expected utilization of the pipeline over the remaining contractual term. Decreases in actual production or natural gas prices could result in future charges related to excess pipeline commitments.

· the existence of operating risks inherent in the oil and gas and oilfield services industries;

· the possibility of changes in tax laws and other laws and regulations;

· the possibility of political or economic instability, civil disturbance, war or acts of terrorism in any of the countries in which we do business; and

· general economic conditions, including the capital and credit markets.

The above description of risks and uncertainties is by no means all-inclusive, but highlights certain factors that we believe are important for your consideration. For a more detailed description of risk factors that may affect us or our industry, please refer to Part I, Item 1A. — Risk Factors in our 2016 Annual Report.

Management Overview

This section is intended to help you understand our results of operations and our financial condition. This information is provided as a supplement to, and should be read in conjunction with, our condensed consolidated financial statements and the accompanying notes thereto.

We own and operate the world’s largest land-based drilling rig fleet and are a leading provider of offshore platform and drilling rigs in the United States and multiple international markets. Our business is comprised of our global land-based and offshore drilling rig operations and other rig services, consisting of equipment manufacturing, rig instrumentation and optimization software. We also specialize in wellbore placement solutions and are a leading provider of directional drilling and MWD systems and services. Our business consists of four reportable operating segments: U.S., Canada, International and Rig Services.

Financial Results

Comparison of the three months ended June 30, 2017 and 2016

Operating revenues for the three months ended June 30, 2017 totaled $631.4 million, representing an increase of $59.8 million, or 10%, compared to the three months ended June 30, 2016. We have seen a significant increase in the number of rigs working in the U.S. since last year, which has led to higher revenues in our U.S. Drilling and Rig Services operating segments. While spot rates for drilling have increased, they still lag the dayrates seen in 2014 before this most recent downturn. Internationally, we experienced a decline in the number of rigs working of approximately 8%, which has partially offset the increases realized in the U.S. Drilling segment.

Net loss from continuing operations totaled $115.5 million for the three months ended June 30, 2017 ($0.41 per diluted share) improved by $71.1 million ($0.24 per diluted share) compared to a net loss from continuing operations of $186.6 million ($0.65 per diluted share) for the three months ended June 30, 2016. Our segment adjusted operating income (loss) was relatively flat period over period with approximately $26.2 million and $25.0 million for the three months ended June 30, 2017 and 2016, respectively.  Partially offsetting this improvement was a $21.7 million reduction in income tax benefits. The improvement in net loss from continuing operations was primarily a result of no longer maintaining an equity method investment in CJES, which accounted for $93.8 million of our net loss for the three months ended June 30, 2016. See Segment Results of Operations for further information on the changes to segment adjusted operating income (loss). 

General and administrative expenses for the three months ended June 30, 2017 totaled $63.7 million, representing an increase of $7.1 million, or 12%, compared to the three months ended June 30, 2016. This is reflective of a slight increase in salaries and other compensation as well as an increase in headcount as activity has accelerated during the latter half of 2016 and has continued into the first half of 2017.

Research and engineering expenses for the three months ended June 30, 2017 totaled $11.3 million, representing an increase of $3.2 million, or 39%, compared to the three months ended June 30, 2016. The increase is a result of increased efforts towards a number of strategic research and engineering projects as the market rebalances and activity begins to accelerate.

Depreciation and amortization expense for the three months ended June 30, 2017 was $208.1 million, representing a decrease of $10.8 million, or 5%, compared to the three months ended June 30, 2016. The decrease was primarily due to the impact from retirements and impairments of various rigs and rig equipment in late 2016.

Segment Results of Operations

Our business consists of four reportable operating segments: U.S., Canada, International and Rig Services. Our Rig Services segment is comprised of our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software services.

Management evaluates the performance of our operating segments using adjusted operating income (loss), which is our segment performance measure, because it believes that this financial measure reflects our ongoing profitability and performance. In addition, securities analysts and investors use this measure as one of the metrics on which they analyze our performance. Adjusted operating income (loss) is computed by subtracting the sum of direct costs, general and administrative expenses, research and engineering expenses and depreciation and amortization from operating revenues.

(1) Represents a measure of the average number of rigs operating during a given period.  For example, one rig operating 45 days during a quarter represents approximately 0.5 average rigs working for the quarter.  On an annual period, one rig operating 182.5 days represents approximately 0.5 average rigs working for the year.

U.S.

Our U.S. Drilling segment includes land drilling activities in the lower 48 states, Alaska and offshore operations in the Gulf of Mexico.

Operating revenues increased during the three months ended June 30, 2017 compared to the corresponding 2016 period primarily due to an 87% increase in the average number of rigs working during the second quarter of 2017 compared to 2016. This increase in activity was the primary contributor to the $47.0 million, or 33%, increase in operating revenues.  While spot rates have been steadily improving over the past year, the dayrates for the incremental drilling rigs going back to work have been lower on average than some of the rigs that have been reaching the end of their contract term. This has had a mitigating impact on our average daily margins, revenues and adjusted operating income.  We expect the average dayrates and margins to continue to improve while the rate of increase in rig activity should slow down over the coming quarters. Additionally, positive results were partially offset by a decrease in operating revenue and adjusted operating income in our offshore operations. Our results for the three months ended June 30, 2016 included a favorable resolution of negotiations for one of our rigs in the Gulf of Mexico, which resulted in partial recovery of standby revenues for past quarters of approximately $20.9 million. The absence of this incremental revenue in combination with a decline in the number of rigs working in the Gulf of Mexico also contributed to the overall decline in operating results.

Canada

Operating results increased during the three months ended June 30, 2017 compared to the corresponding 2016 period due to an increase in drilling rig activity, as evidenced by the increase in average number of rigs working during the second quarter of 2017 compared to 2016. The second quarter is typically the seasonal low for Canada, due to a usual drop in activity for the spring break-up. However, activity levels in general are continuing to improve in Canada as evidenced by the significant improvement in both average rigs working and adjusted operating income (loss) from the comparable period last year.

38

International

Operating results decreased during the three months ended June 30, 2017 compared to the corresponding 2016 period primarily due to an 8% reduction in average number of rigs working during the second quarter of 2017 compared to 2016. This decline in activity and utilization is attributed primarily to Algeria, Angola, Kazakhstan and Russia. Partially offsetting these declines was a significant increase in income driven by increased drilling activity in Colombia.

Rig Services

Operating results increased during the three months ended June 30, 2017 compared to the corresponding 2016 period primarily due to the increase in drilling activity in the U.S. for the period and in the demand for our products and services. The revenue increase in the segment is driven by both an increase in capital equipment deliveries from Canrig and also increases from our Nabors Drilling Solutions (“NDS”) division. The latter saw significant increases in demand for our performance tools, such as ROCKit® and REVit®, as well as wellbore placement services, as the rig activity in the U.S. has increased significantly. Approximately $10.6 million of the increase in the adjusted operating income (loss) of this operating segment is attributable to NDS.

Other Financial Information

Earnings (losses) from unconsolidated affiliates

Earnings (losses) from unconsolidated affiliates represents our share of the net income (loss), as adjusted for our basis differences, of our equity method investments. We previously accounted for our investment in CJES under the equity method on a one-quarter lag through June 30, 2016. On July 20, 2016, CJES voluntarily filed for protection under Chapter 11 of the Bankruptcy Code. As a result, beginning with the third quarter of 2016, we ceased accounting for our investment under the equity method of accounting. The three months ended June 30, 2016 includes our share of the net income (loss) of CJES from January 1, 2016 through March 31, 2016, resulting in a loss of $54.8 million.

Interest expense

Interest expense for the three months ended June 30, 2017 was $54.7 million, representing an increase of $9.5 million, or 21%, compared to the three months ended June 30, 2016. The increase was primarily due to the additional interest expense related to the issuance of $600 million in aggregate principal amount of 5.5% senior notes due 2023 during December 2016 as well as the issuance of $575 million in aggregate principal amount of 0.75% senior exchangeable notes due 2024 during January 2017. This increase was partially offset by a reduction in interest expense due to the repayment of the term loan facility and the redemption of approximately $200 million in aggregate principal amount of 6.15% senior notes due 2018.

Other, net

Other, net for the three months ended June 30, 2017 was $10.1 million of expense, which included a loss on debt buy-backs of $7.3 million, foreign currency exchange losses of $1.6 million and increases to our litigation reserves of $0.8 million. These losses were partially offset by a net gain on sales and disposals of assets of approximately $2.7 million.

Other, net for the three months ended June 30, 2016 was $74.6 million of expense, the majority of which, or $42.9 million, is attributable to impairments associated with our CJES holdings. During the second quarter of 2016, we determined our investment was other than temporarily impaired and recorded a charge of $39.0 million to write off the remaining value of our investment. The balance of the impairment was attributable to professional fees incurred in connection with defending our interests related to CJES filing for protection under Chapter 11 of the Bankruptcy Code on July 20, 2016. Further contributing to the expense for the quarter were net losses on sales and disposals of assets of approximately $28.7 million, inclusive of a $19.7 million charge related to a reserve for amounts associated with our retained interest in the oil and gas properties located on the North Slope of Alaska, and foreign currency exchange losses of approximately $2.8 million.

39

Income tax rate

Our worldwide effective tax rate for the three months ended June 30, 2017 was 14.4% compared to 18.1% for the three months ended June 30, 2016. The change was attributable to the effect of the geographic mix of pre-tax earnings (losses), partially attributable to higher earnings from the increase in activity in the U.S. Drilling segment.

Discontinued Operations

Our discontinued operations for the three months ended June 30, 2017 and 2016 consisted of our historical wholly owned oil and gas businesses. Income (loss) from discontinued operations for the three months ended June 30, 2017 was a loss of $15.5 million compared to a loss of $1.0 million for the three months ended June 30, 2016. Our net loss during the three months ended June 30, 2017 was primarily due to a $16.5 million charge related to the settlement of litigation associated with our previously owned Ramshorn International properties.

Comparison of the six months ended June 30, 2017 and 2016

Operating revenues for the six months ended June 30, 2017 totaled $1.2 billion, representing an increase of $24.7 million, or 2%, compared to the six months ended June 30, 2016. We experienced an increase in operating revenue across the majority of our operating segments as we ramped up activity across the U.S. and Canada. Although we have seen an increase in activity, spot pricing remains under pressure which constrains our ability to fully realize the benefit from the increase in overall activity. Internationally, we experienced a decline in the number of rigs working of approximately 14%, which further impacted operating revenue.

Net loss from continuing operations totaled $263.1 million for the six months ended June 30, 2017 ($0.93 per diluted share) compared to a net loss from continuing operations of $583.2 million ($2.06 per diluted share) for the six months ended June 30, 2016. This improvement was primarily a result of no longer maintaining an equity method investment in CJES, which accounted for $442.0 million of our net loss for the six months ended June 30, 2016 related to our share of the net loss of CJES as well as impairment charges associated with the investment. Approximately $90.5 million and $43.6 million of the net loss for the six months ended June 30, 2017 and 2016, respectively, was attributable to our segment adjusted operating income (loss), which is our primary measure of operating performance.  See Segment Results of Operations for further information on the changes to segment adjusted operating income (loss). 

General and administrative expenses for the six months ended June 30, 2017 totaled $127.1 million, representing an increase of $8.1 million, or 7%, compared to the six months ended June 30, 2016. This is reflective of a slight increase in salaries and other compensation as well as increases in headcount as activity begins to accelerate during 2017.

Research and engineering expenses for the six months ended June 30, 2017 totaled $23.1 million, representing an increase of $6.8 million, or 41%, compared to the six months ended June 30, 2016. The increase is a result of increased efforts towards a number of strategic research and engineering projects as the market rebalances and activity begins to accelerate.

Depreciation and amortization expense for the six months ended June 30, 2017 was $411.8 million, representing a decrease of $23.0 million, or 5%, compared to the six months ended June 30, 2016. The decrease was primarily due to the impact from retirements and impairments of various rigs and rig equipment in late 2016.

(1) Represents a measure of the average number of rigs operating during a given period.  For example, one rig operating 45 days during a quarter represents approximately 0.5 average rigs working for the quarter.  On an annual period, one rig operating 182.5 days represents approximately 0.5 average rigs working for the year.

U.S.

Operating revenues increased during the six months ended June 30, 2017 compared to the corresponding 2016 period primarily due to a 60% increase in the average number of rigs working during the first six months of 2017 compared to 2016. This increase in activity was the primary contributor to the $60.3 million, or 21%, increase in operating revenues.  As noted above, while spot rates have been steadily improving over the past year, the dayrates for the incremental drilling rigs going back to work have been lower on average than some of the rigs that have been reaching the end of their contract term. This has had a mitigating impact on our average daily margins and adjusted operating income.  We expect the average dayrates and margins to continue to improve while the rate of increase in rig activity should slow down over the coming quarters. Additionally, positive results were partially offset by a decrease in operating revenue and adjusted operating income in our offshore operations. Our results for the six months ended June 30, 2016 included a favorable resolution of negotiations for one of our rigs in the Gulf of Mexico, which resulted in partial recovery of standby revenues for past quarters of approximately $20.9 million. The absence of this incremental revenue in combination with a decline in the number of rigs working in the Gulf of Mexico also contributed to the overall decline in operating results.

Canada

Operating results increased during the six months ended June 30, 2017 compared to the corresponding 2016 period due to an increase in drilling rig activity, as evidenced by the increase in average number of rigs working during the first six months of 2017 compared to 2016.

International

Operating results decreased during the six months ended June 30, 2017 compared to the corresponding 2016 period primarily due to the loss of revenue and increased costs related to downtime incurred to perform structural work on many of our rigs in our largest international market. Additionally, results were negatively impacted by a 14% reduction in average number of rigs working during the first six months of 2017 compared to 2016. Partially offsetting these declines were increased drilling activity in Colombia and Kuwait.

41

Rig Services

Operating results increased during the six months ended June 30, 2017 compared to the corresponding 2016 period primarily due to the significant increase in drilling activity in the U.S. for the period and in the demand for our products and services. The revenue increase in the segment is driven by both an increase in capital equipment deliveries from Canrig and also increases from our NDS division. The latter saw significant increases in demand for our performance tools, such as ROCKit® and REVit®, as well as wellbore placement services, as the rig activity in the U.S. has increased significantly. Approximately $11.7 million of the increase in the adjusted operating income (loss) of this operating segment is attributable to NDS.

Other Financial Information

Earnings (losses) from unconsolidated affiliates

Earnings (losses) from unconsolidated affiliates represents our share of the net income (loss), as adjusted for our basis differences, of our equity method investments. We previously accounted for our investment in CJES under the equity method on a one-quarter lag through June 30, 2016. On July 20, 2016, CJES voluntarily filed for protection under Chapter 11 of the Bankruptcy Code. As a result, beginning with the third quarter of 2016, we ceased accounting for our investment under the equity method of accounting. The six months ended June 30, 2016 includes our share of the net income (loss) of CJES from October 1, 2015 through March 31, 2016, resulting in a loss of $221.9 million, inclusive of charges of $138.5 million representing our share of CJES’s fixed asset impairment charges for the period.

Interest expense

Interest expense for the six months ended June 30, 2017 was $111.2 million, representing an increase of $20.2 million, or 22%, compared to the six months ended June 30, 2016. The increase was primarily due to the additional interest expense related to the issuance of $600 million in aggregate principal amount of 5.5% senior notes due 2023 during December 2016 as well as the issuance of $575 million in aggregate principal amount of 0.75% senior exchangeable notes due 2024 during January 2017. This increase was partially offset by a reduction in interest expense due to the repayment of the term loan facility in conjunction with the repurchase or redemption of approximately $362.5 million in aggregate principal amount of 6.15% senior notes due 2018.

Other, net

Other, net for the six months ended June 30, 2017 was $23.6 million of expense, which included a loss on debt buy-backs of $15.9 million, foreign currency exchange losses of $2.5 million and increases to our litigation reserves of $1.6 million.

Other, net for the six months ended June 30, 2016 was $257.0 million of expense. This was primarily composed of impairments associated with our CJES holdings in the amount of $220.1 million resulting from declines in the fair value of our investment including other than temporary impairment charges of $192.4 million and other charges culminating from litigation expenses surrounding the bankruptcy proceedings and the reserve of certain other amounts associated with our CJES holdings, including affiliate receivables of $27.7 million. Further contributing to the expense for the period were net losses on sales and disposals of assets of approximately $34.0 million, inclusive of $22.4 million in write downs to our oil and gas properties located on the North Slope of Alaska, and foreign currency exchange losses of approximately $7.0 million, partially offset by a net gain on debt buybacks of approximately $6.0 million.

Income tax rate

Our worldwide effective tax rate for the six months ended June 30, 2017 was 14.6% compared to 13.8% for the six months ended June 30, 2016. The change was attributable to the effect of the geographic mix of pre-tax earnings (losses), partially attributable to higher earnings from the increase in activity in the U.S. Drilling segment.  The tax effect of our share of the net loss of CJES for the six months ended June 30, 2016 also contributed to the change.

42

Discontinued Operations

Our discontinued operations for the six months ended June 30, 2017 and 2016 consisted of our historical wholly owned oil and gas businesses. Income (loss) from discontinued operations for the six months ended June 30, 2017 was a loss of $15.9 million compared to a loss of $1.9 million for the six months ended June 30, 2016. Our net loss for the six months ended June 30, 2017 was primarily due to a $16.5 million charge related to the settlement of litigation associated with our previously owned Ramshorn International properties.

Liquidity and Capital Resources

Financial Condition and Sources of Liquidity

Our primary sources of liquidity are cash and investments and availability under our revolving credit facility and commercial paper program. As of June 30, 2017, we had cash and short-term investments of $232.0 million and working capital of $297.6 million, both amounts include $40.0 million in cash to be used exclusively by the joint venture to fund future operations. As of December 31, 2016, we had cash and short-term investments of $295.2 million and working capital of $333.9 million. At June 30, 2017, we had $272.0 million outstanding under our $2.25 billion revolving credit facility and commercial paper program.

In December 2016, Nabors Delaware completed an offering of $600 million aggregate principal amount of 5.50% senior unsecured notes due January 15, 2023, which are fully and unconditionally guaranteed by Nabors. The proceeds from this offering were used to prepay the $162.5 million portion under our unsecured term loan that was due in 2018 and all amounts then outstanding under our $2.25 billion revolving credit facility and commercial paper program, or $392.1 million. The remaining proceeds were allocated for general corporate purposes, including to repay and repurchase debt. 

In January 2017, Nabors Delaware issued $575 million in aggregate principal amount of its 0.75% exchangeable senior unsecured notes due 2024, which are fully and unconditionally guaranteed by Nabors. The net proceeds from the offering of the exchangeable notes were used to prepay the remaining balance of our unsecured term loan originally scheduled to mature in 2020, as well as to pay approximately $40.3 million for the cost of the capped call transactions entered into in connection with the offering. The remaining net proceeds from the offering were allocated for general corporate purposes, including the repurchase of approximately $162.5 million aggregate principal amount of our 6.15% senior notes due February 2018.

We had 15 letter-of-credit facilities with various banks as of June 30, 2017. Availability under these facilities as of June 30, 2017 was as follows:

	June 30,
	2017
	(In thousands)
Credit available	$	758,906
Less: Letters of credit outstanding, inclusive of financial and performance guarantees		129,674
Remaining availability	$	629,232

Our ability to access capital markets or to otherwise obtain sufficient financing is enhanced by our senior unsecured debt ratings as provided by the major credit rating agencies in the United States and our historical ability to access these markets as needed. While there can be no assurances that we will be able to access these markets in the future, we believe that we will be able to access capital markets or otherwise obtain financing in order to satisfy any payment obligation that might arise upon exchange or purchase of our notes and that any cash payment due, in addition to our other cash obligations, would not ultimately have a material adverse impact on our liquidity or financial position. A ratings downgrade could adversely impact our ability to access debt markets in the future, increase the cost of future debt, and potentially require us to post letters of credit for certain obligations.

Our gross debt to capital ratio was 0.55:1 as of June 30, 2017 and 0.52:1 as of December 31, 2016. Our net debt to capital ratio was 0.53:1 as of June 30, 2017 and 0.50:1 as of December 31, 2016. The gross debt to capital ratio is calculated by dividing (x) total debt by (y) total capital. Total capital is defined as total debt plus total equity. Net debt is defined as total debt minus the sum of cash and cash equivalents and short-term investments. Availability under the revolving credit facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. Neither the gross debt

43

to capital ratio nor the net debt to capital ratio is a measure of operating performance or liquidity defined by GAAP and may not be comparable to similarly titled measures presented by other companies.

Our interest coverage ratio was 2.6:1 as of June 30, 2017 and 3.4:1 as of December 31, 2016. The interest coverage ratio is a trailing 12-month quotient of the sum of (x) operating revenues, direct costs, general and administrative expenses and research and engineering expenses divided by (y) interest expense. The interest coverage ratio is not a measure of operating performance or liquidity defined by GAAP and may not be comparable to similarly titled measures presented by other companies.

Our current cash and investments, projected cash flows from operations and our revolving credit facility are expected to adequately finance our purchase commitments, capital expenditures, acquisitions, scheduled debt service requirements, and all other expected cash requirements for the next 12 months.

Future Cash Requirements

We expect capital expenditures over the next 12 months to be less than $0.8 billion. Purchase commitments outstanding at June 30, 2017 totaled approximately $223.4 million, primarily for rig-related enhancements, new rig equipment, as well as sustaining capital expenditures, other operating expenses and purchases of inventory. We can reduce planned expenditures if necessary or increase them if market conditions and new business opportunities warrant it. The level of our outstanding purchase commitments and our expected level of capital expenditures over the next 12 months represent a number of capital programs that are currently underway or planned. We believe these programs will result in the enhancement of a significant number of rigs in our existing Lower 48 fleet. When the programs are completed, we expect to have a larger fleet of high-specification land rigs deployed in the Lower 48. We believe the capabilities of these high-specification rigs will meet or exceed requirements from customers.

We have historically completed a number of acquisitions and will continue to evaluate opportunities to acquire assets or businesses to enhance our operations. Several of our previous acquisitions were funded through issuances of debt or our common shares. Future acquisitions may be funded using existing cash or by issuing debt or additional shares of our stock. Such capital expenditures and acquisitions will depend on our view of market conditions and other factors.

See our discussion of guarantees issued by Nabors that could have a potential impact on our financial position, results of operations or cash flows in future periods included below under “Off-Balance Sheet Arrangements (Including Guarantees)”.

There have been no material changes to the contractual cash obligations table that was included in our 2016 Annual Report.

On August 25, 2015, our Board of Directors authorized a share repurchase program (the “program”) under which we may repurchase, from time to time, up to $400 million of our common shares by various means, including in the open market or in privately negotiated transactions. This authorization does not have an expiration date and does not obligate us to repurchase any of our common shares. Through June 30, 2017, we repurchased 10.9 million of our common shares for an aggregate purchase price of approximately $101.3 million under this program. As of June 30, 2017, the remaining amount authorized under the program that may be used to purchase shares was $298.7 million. The repurchased shares, which are held by our subsidiaries, are registered and tradable subject to applicable securities law limitations and have the same voting and other rights as other outstanding shares. As of June 30, 2017, our subsidiaries held 49.7 million of our common shares.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, both in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors and may involve material amounts.

44

Cash Flows

Our cash flows depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Sustained decreases in the price of oil or natural gas could have a material impact on these activities, and could also materially affect our cash flows. Certain sources and uses of cash, such as the level of discretionary capital expenditures or acquisitions, purchases and sales of investments, loans, issuances and repurchases of debt and of our common shares are within our control and are adjusted as necessary based on market conditions. We discuss our cash flows for the six months ended June 30, 2017 and 2016 below.

Operating Activities.  Net cash used for operating activities totaled $9.5 million during the six months ended June 30, 2017, compared to net cash provided of $336.7 million during the corresponding 2016 period. Operating cash flows are our primary source of capital and liquidity. The decrease in our operating cash flows was due to a combination of lower earnings for the period ended June 30, 2017, as well as a substantial turnaround in cash required for working capital. Changes in working capital items such as collection of receivables, other deferred revenue arrangements and payments of operating payables are significant factors affecting operating cash flows. Changes in working capital items used $108.9 million and provided $114.4 million in cash during the six months ended June 30, 2017 and 2016, respectively. This represents a $223.3 million swing in cash generation as operating revenues and activity are increasing during the current period, which increases our working capital requirements. This compares to the 2016 period, where operating revenues and activity were still trending downward, which resulted in operating cash flow benefits from working capital. The balance of the decrease is attributable to reduced earnings during the 2017 period compared to the 2016 period.

Investing Activities.  Net cash used for investing activities totaled $289.4 million during the six months ended June 30, 2017 compared to $179.0 million during the corresponding 2016 period. Our primary use of cash for investing activities is for capital expenditures related to rig-related enhancements, new construction and equipment, as well as sustaining capital expenditures. During the six months ended June 30, 2017 and 2016, we used cash for capital expenditures totaling $315.8 million and $193.2 million, respectively.

Financing Activities.  Net cash provided by financing activities totaled $230.4 million during the six months ended June 30, 2017 compared to net cash used of $178.4 million during the corresponding 2016 period. During the six months ended June 30, 2017, we received net proceeds of $519.9 million in connection with the issuance of our exchangeable senior unsecured notes and $272.0 million in amounts borrowed under our commercial paper program and revolving credit facility.  This was partially offset by the repayment of the remaining balance of our unsecured term loan of $162.5 million and the repurchase or redemption of $378.0 million, reflecting principal and premiums incurred in connection with these repurchases, in long-term debt due in 2018.  Additionally, we paid dividends of $34.2 million and received proceeds of $8.3 million due to stock options exercised and $20.0 million in contributions from non-controlling interest.  During the six months ended June 30, 2016, we repurchased $148.0 million in long-term debt coupled with the payment of $16.9 million in dividends to shareholders.

Other Matters

Recent Accounting Pronouncements

See Note 2 — Summary of Significant Accounting Policies.

Off-Balance Sheet Arrangements (Including Guarantees)

We are a party to transactions, agreements or other contractual arrangements defined as “off-balance sheet arrangements” that could have a material future effect on our financial position, results of operations, liquidity and capital resources. The most significant of these off-balance sheet arrangements involve agreements and obligations under which we provide financial or performance assurance to third parties. Certain of these agreements serve as guarantees, including standby letters of credit issued on behalf of insurance carriers in conjunction with our workers’ compensation insurance program and other financial surety instruments such as bonds. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by us to our share transfer agent and our insurance carriers. We are not able to estimate the potential future maximum payments that might be due under our indemnification guarantees. Management believes the likelihood that we would be required to perform or otherwise incur any material losses associated with any of these guarantees is remote.

45

The following table summarizes the total maximum amount of financial guarantees issued by Nabors:

	Maximum Amount
	2017		2018	2019	Thereafter	Total
	(In thousands)
Financial standby letters of credit and other financial surety instruments	$	126,575	140,275	—	—	$	266,850

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We may be exposed to market risks arising from the use of financial instruments in the ordinary course of business as discussed in our 2016 Annual Report. There were no material changes in our exposure to market risk during the six months ended June 30, 2017 from those disclosed in our 2016 Annual Report.

ITEM 4. CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d‑15(e) under the Exchange Act) designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure. We have investments in certain unconsolidated entities that we do not control or manage. Because we do not control or manage these entities, our disclosure controls and procedures with respect to these entities are necessarily more limited than those we maintain with respect to our consolidated subsidiaries.

The Company’s management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report

There were no changes in our internal control over financial reporting during the quarter ended June 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. For matters where an unfavorable outcome is reasonably possible and significant, we disclose the nature of the matter and a range of potential exposure, unless an estimate cannot be made at the time of disclosure. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our condensed consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period. See Note 7 — Commitments and Contingencies for a description of such proceedings.

ITEM 1A. RISK FACTORS

There have been no material changes to the risks described in Item 1A. Risk Factors in our 2016 Annual Report, which in addition to the information set forth elsewhere in this report, should be carefully considered when evaluating us. These risks are not the only ones we face. Additional risks not presently known to us or that we currently deem immaterial may also impair our business.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We withheld the following shares of our common stock to satisfy tax withholding obligations in connection with grants of stock awards during the three months ended June 30, 2017 from the distributions described below. These shares may be deemed to be “issuer purchases” of shares that are required to be disclosed pursuant to this Item, but were not purchased as part of a publicly announced program to purchase common shares:

					Approximated
				Total Number	Dollar Value of
				of Shares	Shares that May

May 1 - May 31	2	$	10.34	—	298,716
June 1 - June 30	161	$	8.84	—	298,716

(1) Shares were withheld from employees and directors to satisfy certain tax withholding obligations due in connection with grants of shares under our 2003 Employee Stock Plan, the 2013 Stock Plan and the 2016 Stock Plan. Each of the 2016 Stock Plan, the 2013 Stock Plan, the 2003 Employee Stock Plan and the 1999 Stock Option Plan for Non-Employee Directors provide for the withholding of shares to satisfy tax obligations, but do not specify a maximum number of shares that can be withheld for this purpose. These shares were not purchased as part of a publicly announced program to purchase common shares.

(2) In August 2015, our Board of Directors authorized a share repurchase program under which we may repurchase up to $400 million of our common shares in the open market or in privately negotiated transactions. Through June 30, 2017, we repurchased 10.9 million of our common shares for an aggregate purchase price of approximately $101.3 million under this program. As of June 30, 2017, we had $298.7 million that remained authorized under the program that may be used to repurchase shares. The repurchased shares are held by our subsidiaries are registered and tradable subject to applicable securities law limitations and have the same voting, dividend and other rights as other outstanding shares. As of June 30, 2017, our subsidiaries held 49.7 million of our common shares.

Note 2 Summary of Significant Accounting Policies

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 June 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 six months ended June 30, 2017 may not be indicative of results that will be realized for the full year ending December 31, 2017.

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 to own, manage and operate onshore drilling rigs in The Kingdom of Saudi Arabia. The joint venture, which is equally owned by Saudi Aramco and Nabors, is expected to commence operations in the second half 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 June 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 3 — Investments in Unconsolidated Affiliates.

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 June 30, 2017 and December 31, 2016, our deferred revenues classified as accrued liabilities were $278.3 million and $255.6 million, respectively. At June 30, 2017 and December 31, 2016, our deferred revenues classified as other long-term liabilities were $191.8 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 June 30, 2017 and December 31, 2016, our deferred expenses classified as other current assets were $69.4 million and $63.4 million, respectively. At June 30, 2017 and December 31, 2016, our deferred expenses classified as other long-term assets were $48.2 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 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:

	June 30,		December 31,
	2017		2016
	(In thousands)
Raw materials	$	86,365	$	84,431
Work-in-progress		8,701		1,204
Finished goods		13,075		17,960
	$	108,141	$	103,595

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

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.

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

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. 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 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 now expanded our population and are reviewing our contracts in order to quantify the consolidated impact of such changes. At this time, we expect to apply the modified retrospective approach during the first quarter of 2018. However, we are still evaluating the requirements to determine the impact of the adoption on our 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. 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 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.

Note 3 Investments in Unconsolidated Affiliates

On March 24, 2015, we completed the merger of our Completion & Production Services business with C&J Energy Services, Inc.. We received total consideration comprised of approximately $693.5 million in cash ($650.0 million after settlement of working capital requirements) and approximately 62.5 million common shares in the combined company, CJES, representing approximately 53% of the outstanding and issued common shares of CJES as of the closing date. We recognized our share of the net income (loss) of CJES, which was a loss of $54.8 million and $221.9 million, respectively, for the three and six months ended June 30, 2016, and is reflected in earnings (losses) from unconsolidated affiliates in our condensed consolidated statements of income (loss). Additionally, we recognized other-than-temporary impairment charges of $39.0 million and $192.4 million, respectively, during the three and six months ended June 30, 2016, which is reflected in other, net in our condensed consolidated statements of income (loss). During the third quarter of 2016, CJES commenced voluntarily cases under chapter 11 of the U.S. Bankruptcy code. As such, we ceased accounting for our investment in CJES as an equity method investment. In January 2017, CJES emerged from bankruptcy and as part of the settlement we received warrants to acquire the common equity in the reorganized CJES.

Fair Value Measurements

Note 4 Fair Value Measurements

Our financial assets and liabilities that are accounted for at fair value on a recurring basis as of June 30, 2017 consist of available-for-sale equity and debt securities. Our debt securities could transfer into or out of a Level 1 or 2 measure depending on the availability of independent and current pricing at the end of each quarter. During the three and six months ended June 30, 2017, there were no transfers of our financial assets between Level 1 and Level 2 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The majority of our short-term investments are categorized as Level 1 and had a fair value of $24.9 million as of June 30, 2017.  Additionally, we report our investment in the CJES warrants at fair value based on quoted market prices or prices quoted from third-party financial institutions. This measure is categorized as Level 2 and had a fair value of $10.6 million as of June 30, 2017.

Nonrecurring Fair Value Measurements

We applied fair value measurements to our nonfinancial assets and liabilities measured on a nonrecurring basis, which consist of measurements primarily to assets held for sale, goodwill, equity method investments, intangible assets and other long-lived assets, assets acquired and liabilities assumed in a business combination and our pipeline contractual commitment. Based upon our review of the fair value hierarchy, the inputs used in these fair value measurements were considered Level 3 inputs.

Fair Value of Financial Instruments

We estimate the fair value of our financial instruments in accordance with GAAP. The fair value of our long-term debt, revolving credit facility and commercial paper is estimated based on quoted market prices or prices quoted from third-party financial institutions. The fair value of our debt instruments is determined using Level 2 measurements. The carrying and fair values of these liabilities were as follows:

(1) The 6.15% senior notes due February 2018 have been classified as long-term because we have the ability and intent to repay this obligation utilizing our revolving credit facility.

During the six months ended June 30, 2017, we repurchased or redeemed $363.2 million aggregate principal amount of our 6.15% senior notes due February 2018 for approximately $382.5 million in cash, reflecting principal and approximately $5.6 million of accrued and unpaid interest. The difference represents the premiums paid in connection with these repurchases or redemptions and is included in other, net in our condensed consolidated statement of income (loss) for the six months ended June 30, 2017.

0.75% Senior Exchangeable Notes Due January 2024

In January 2017, Nabors Industries, Inc. (“Nabors Delaware”), a wholly owned subsidiary of Nabors, issued $575 million in aggregate principal amount of 0.75% exchangeable senior unsecured notes due 2024, which are fully and unconditionally guaranteed by Nabors. The notes bear interest at a rate of 0.75% per year payable semiannually on January 15 and July 15 of each year, beginning on July 15, 2017. The exchangeable notes are bifurcated for accounting purposes into debt and equity components of $411.2 million and $163.8 million, respectively, based on the relative fair value. Debt issuance costs of $9.6 million and equity issuance costs of $3.9 million were capitalized in connection with the issuance of these notes in long-term debt and netted against the proceeds allocated to the equity component, respectively, in our condensed consolidated balance sheet. The debt issuance costs are being amortized through January 2024.

The exchangeable notes are exchangeable, under certain conditions, at an initial exchange rate of 39.75 common shares of Nabors per $1,000 principal amount of exchangeable notes (equivalent to an initial exchange price of approximately $25.16 per common share). Upon any exchange, Nabors Delaware will settle its exchange obligation in cash, common shares of Nabors, or a combination of cash and common shares, at our election.

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions which are expected to reduce potential dilution to common shares and/or offset potential cash payments required to be made in excess of the principal amount upon any exchange of notes. Such reduction and/or offset is subject to a cap representing a price per share of $31.45, an approximately 75.0% premium over our share price of $17.97 as of the date of the transaction.

The net proceeds from the offering of the exchangeable notes were used to prepay the remaining balance of our unsecured term loan originally scheduled to mature in 2020, as well as to pay the cost of the capped call transactions. The remaining net proceeds from the offering were allocated for general corporate purposes, including to repurchase or repay other indebtedness.

Commercial Paper Program

As of June 30, 2017, we had approximately $172.0 million of commercial paper outstanding. The weighted average interest rate on borrowings at June 30, 2017 was 1.63%.  Our commercial paper borrowings are classified as long-term debt because the borrowings are fully supported by availability under our revolving credit facility, which matures as currently structured in July 2020, more than one year from now.

Revolving Credit Facility

As of June 30, 2017, we had $100.0 million outstanding under our $2.25 billion revolving credit facility, which matures in July 2020. The weighted average interest rate on borrowings at June 30, 2017 was 2.52%. The revolving credit facility contains various covenants and restrictive provisions that limit our ability to incur additional indebtedness, make investments or loans and create liens and require us to maintain a net funded indebtedness to total capitalization ratio, as defined in the agreement. Availability under the revolving credit facility is subject to a covenant not to exceed a net debt to capital ratio of 0.60:1. We were in compliance with all covenants under the agreement at June 30, 2017. If we fail to perform our obligations under the covenants, the revolving credit commitment could be terminated, and any outstanding borrowings under the facility could be declared immediately due and payable.

Term Loan Facility

On September 29, 2015, Nabors Delaware entered into a new five-year unsecured term loan facility for $325.0 million, which is fully and unconditionally guaranteed by us. The term loan facility contained a mandatory prepayment of $162.5 million due in September 2018, which was repaid in December 2016 utilizing a portion of the proceeds received in connection with the 5.50% senior notes offering. In January 2017, we repaid the remaining $162.5 million term loan utilizing the proceeds received in connection with the 0.75% senior exchangeable notes and the facility was terminated.

Note 7 Commitments and Contingencies

Contingencies

Income Tax

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries, if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could change substantially.

We have received an assessment from a tax authority in Latin America in connection with a 2007 income tax return. The assessment relates to the denial of depreciation expense deductions related to drilling rigs. Similar deductions were taken for tax year 2009. Although Nabors and its tax advisors believe these deductions are appropriate and intend to continue to defend our position, we have recorded a partial reserve to account for this contingency. If we ultimately do not prevail, we estimate that we would be required to recognize additional tax expense in the range of $3 million to $8 million.  

Self-Insurance

We estimate the level of our liability related to insurance and record reserves for these amounts in our condensed consolidated financial statements. Our estimates are based on the facts and circumstances specific to existing claims and our past experience with similar claims. These loss estimates and accruals recorded in our financial statements for claims have historically been reasonable in light of the actual amount of claims paid and are actuarially supported. Although we believe our insurance coverage and reserve estimates are reasonable, a significant accident or other event that is not fully covered by insurance or contractual indemnity could occur and could materially affect our financial position and results of operations for a particular period.

We self-insure for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Some of our workers’ compensation, employers’ liability and marine employers’ liability claims are subject to a $3.0 million per-occurrence deductible; additionally, some of our automobile liability claims are subject to a $2.5 million deductible. General liability claims remain subject to a $5.0 million per-occurrence deductible. Our policies were renewed effective April 1, 2017 and remain subject to these same deductibles.

In addition, we are subject to a $5.0 million deductible for land rigs and for offshore rigs. This applies to all kinds of risks of physical damage except for named windstorms in the U.S. Gulf of Mexico for which we are self-insured.

Litigation

Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. For matters where an unfavorable outcome is reasonably possible and significant, we disclose the nature of the matter and a range of potential exposure, unless an estimate cannot be made at the time of disclosure. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.

In March 2011, the Court of Ouargla entered a judgment of approximately $26.2 million (at June 30, 2017 exchange rates) against us relating to alleged violations of Algeria’s foreign currency exchange controls, which require that goods and services provided locally be invoiced and paid in local currency. The case relates to certain foreign currency payments made to us by CEPSA, a Spanish operator, for wells drilled in 2006. Approximately $7.5 million of the total contract amount was paid offshore in foreign currency, and approximately $3.2 million was paid in local currency. The judgment includes fines and penalties of approximately four times the amount at issue. We have appealed the ruling based on our understanding that the law in question applies only to resident entities incorporated under Algerian law. An intermediate court of appeals upheld the lower court’s ruling, and we appealed the matter to the Supreme Court. On September 25, 2014, the Supreme Court overturned the verdict against us, and the case was reheard by the Ouargla Court of Appeals on March 22, 2015 in light of the Supreme Court’s opinion. On March 29, 2015, the Ouargla Court of Appeals reinstated the initial judgment against us. We have appealed this decision again to the Supreme Court. While our payments were consistent with our historical operations in the country, and, we believe, those of other multinational corporations there, as well as interpretations of the law by the Central Bank of Algeria, the ultimate resolution of this matter could result in a loss of up to $18.2 million in excess of amounts accrued.

In March 2012, Nabors Global Holdings II Limited (“NGH2L”) signed an agreement with ERG Resources, LLC (“ERG”) relating to the sale of all of the Class A shares of NGH2L’s wholly owned subsidiary, Ramshorn International Limited, an oil and gas exploration company (“Ramshorn”) (“the ERG Agreement”). When ERG failed to meet its closing obligations, NGH2L terminated the transaction on March 19, 2012 and, as contemplated in the agreement, retained ERG’s $3.0 million escrow deposit. ERG filed suit the following day in the 61st Judicial District Court of Harris County, Texas, in a case styled ERG Resources, LLC v. Nabors Global Holdings II Limited, Ramshorn International Limited, and Parex Resources, Inc.; Cause No. 2012 16446, seeking injunctive relief to halt any sale of the shares to a third party, specifically naming as defendant Parex Resources, Inc. (“Parex”). The lawsuit also sought monetary damages of up to $750.0 million based on an alleged breach of contract by NGH2L and alleged tortious interference with contractual relations by Parex. We successfully defeated ERG’s effort to obtain a temporary restraining order from the Texas court on March 20, 2012 and completed the sale of Ramshorn’s Class A shares to a Parex affiliate in April 2012, which mooted ERG’s application for a temporary injunction. The defendants made numerous jurisdictional challenges on appeal, and on April 30, 2015, ERG filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code. Accordingly, the civil actions are currently subject to the bankruptcy stay and ERG’s claims in the lawsuit are assets of the estate. The lawsuit was stayed, pending further court actions, including appeals of the jurisdictional decisions. On June 17, 2016, the Texas Supreme Court issued its opinion on the jurisdictional appeal holding that jurisdiction exists in Texas for Ramshorn, but not for Parex Bermuda or Parex Canada. ERG retains its causes of action for monetary damages, but we believe the claims are foreclosed by the terms of the ERG Agreement and are without factual or legal merit. On December 28, 2016, the District Court granted Nabors’ Motion for Partial Summary Judgment to Enforce Exclusive Remedies Clause, holding that ERG’s potential recovery in the action may not exceed $4.5 million in accordance with the terms of the ERG Agreement. The plaintiffs challenged this ruling and Parex was poised to enter into a settlement agreement, over the objection of Nabors, whereby ERG would release Parex from all claims in exchange for a $15 million cash payment from Parex. The Parex settlement changed the dynamics of the ongoing litigation between Nabors and ERG, with all signs indicating that the bankrupt ERG intended to use the cash influx from Parex to pursue a low‐risk but potentially high‐reward strategy by continuing with its claim against Nabors. With this development Nabors re‐evaluated its options, noting that however remote, a negative outcome at trial had the potential for a significantly adverse financial impact. As a result, in order to mitigate expenses associated with what was proving to be lengthy and potentially costly litigation, Nabors has agreed to a settlement in which ERG will release NGH2L from all claims in exchange for a payment of $20 million by NGH2L. This settlement resulted in a pre-tax charge of $16.5 million, which is included in net income (loss) from discontinued operations within our condensed consolidated statement of income for the three and six months ended June 30, 2017. The parties are working on documenting the settlement, which will not include an admission of wrongdoing by NGH2L. It is anticipated that the settlement, including the payment from NGH2L, will occur during the third quarter of 2017.

Off-Balance Sheet Arrangements (Including Guarantees)

We are a party to some transactions, agreements or other contractual arrangements defined as “off-balance sheet arrangements” that could have a material future effect on our financial position, results of operations, liquidity and capital resources. The most significant of these off-balance sheet arrangements involve agreements and obligations under which we provide financial or performance assurance to third parties. Certain of these agreements serve as guarantees, including standby letters of credit issued on behalf of insurance carriers in conjunction with our workers’ compensation insurance program and other financial surety instruments such as bonds. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by Nabors to our share transfer agent and our insurance carriers. We are not able to estimate the potential future maximum payments that might be due under our indemnification guarantees.

Management believes the likelihood that we would be required to perform or otherwise incur any material losses associated with any of these guarantees is remote. The following table summarizes the total maximum amount of financial guarantees issued by Nabors:

Earnings (Losses) Per Share

Earnings (Losses) Per Share

Note 8 Earnings (Losses) Per Share

ASC 260, Earnings per Share, requires companies to treat unvested share-based payment awards that have nonforfeitable rights to dividends or dividend equivalents as a separate class of securities in calculating earnings (losses) per share. We have granted and expect to continue to grant to employees restricted stock grants that contain nonforfeitable rights to dividends. Such grants are considered participating securities under ASC 260. As such, we are required to include these grants in the calculation of our basic earnings (losses) per share and calculate basic earnings (losses) per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings.

Basic earnings (losses) per share is computed utilizing the two-class method and is calculated based on the weighted-average number of common shares outstanding during the periods presented.

Diluted earnings (losses) per share is computed using the weighted-average number of common and common equivalent shares outstanding during the periods utilizing the two-class method for stock options and unvested restricted stock. Shares issuable upon exchange of the $575 million 0.75% exchangeable notes are not included in the calculation of diluted earnings (losses) per share unless the exchange value of the notes exceeds their principal amount at the end of the relevant reporting period, in which case the notes will be accounted for as if the number of common shares that would be necessary to settle the excess are issued. Such shares are only included in the calculation of the weighted-average number of shares outstanding in our diluted earnings (losses) per share calculation, when the price of our shares exceeds $25.16 on the last trading day of the quarter, which did not occur during the six months ended June 30, 2017.

A reconciliation of the numerators and denominators of the basic and diluted earnings (losses) per share computations is as follows:

For all periods presented, the computation of diluted earnings (losses) per share excludes outstanding stock options with exercise prices greater than the average market price of Nabors’ common shares, because their inclusion would be anti-dilutive and because they are not considered participating securities. For periods in which we experience a net loss from continuing operations, all potential common shares have been excluded from the calculation of weighted-average shares outstanding, because their inclusion would be anti-dilutive. The average number of options that were excluded from diluted earnings (losses) per share that would potentially dilute earnings per share in the future were as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2017		2016		2017		2016
Potentially dilutive securities excluded as anti-dilutive		4,469,382		5,379,424		4,558,594		5,397,068

In any period during which the average market price of Nabors’ common shares exceeds the exercise prices of these stock options, such stock options will be included in our diluted earnings (losses) per share computation using the if-converted method of accounting. Restricted stock is included in our basic and diluted earnings (losses) per share computation using the two-class method of accounting in all periods because such stock is considered participating securities.

Note 10 Assets Held for Sale and Discontinued Operations

Assets Held for Sale

Assets held for sale as of June 30, 2017 and December 31, 2016 was $78.4 million and $76.7 million, respectively. These assets consisted primarily of our oil and gas holdings which are mainly in the Horn River basin in western Canada of $67.2 million and $65.0 million, respectively, as of the periods noted above and the operating results have been reflected in discontinued operations. The remainder represents assets that meet the criteria to be classified as assets held for sale, but do not represent a disposal of a component of an entity or a group of components of an entity representing a strategic shift that has or will have a major effect on the entity's operations and financial results.

The carrying value of our assets held for sale represents the lower of carrying value or fair value less costs to sell. We continue to market these properties at prices that are reasonable compared to current fair value.

Our liabilities held for sale as of June 30, 2017 includes a $20.0 million reserve in connection with the settlement of litigation associated with our previously owned Ramshorn International properties.

We have contracts with pipeline companies to pay specified fees based on committed volumes for gas transport and processing associated with these properties held for sale. At June 30, 2017, our undiscounted contractual commitments for these contracts approximated $14.3 million and we had liabilities of $10.7 million, $5.8 million of which were classified as current and were included in accrued liabilities. At December 31, 2016, our undiscounted contractual commitments for these contracts approximated $17.2 million and we had liabilities of $12.5 million, $5.5 million of which were classified as current and were included in accrued liabilities.

The amounts at each balance sheet date represented our best estimate of the fair value of the excess capacity of the pipeline commitments calculated using a discounted cash flow model, when considering our disposal plan, current production levels, natural gas prices and expected utilization of the pipeline over the remaining contractual term. Decreases in actual production or natural gas prices could result in future charges related to excess pipeline commitments.

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 June 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 six months ended June 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 to own, manage and operate onshore drilling rigs in The Kingdom of Saudi Arabia. The joint venture, which is equally owned by Saudi Aramco and Nabors, is expected to commence operations in the second half 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 June 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 3 — 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 June 30, 2017 and December 31, 2016, our deferred revenues classified as accrued liabilities were $278.3 million and $255.6 million, respectively. At June 30, 2017 and December 31, 2016, our deferred revenues classified as other long-term liabilities were $191.8 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 June 30, 2017 and December 31, 2016, our deferred expenses classified as other current assets were $69.4 million and $63.4 million, respectively. At June 30, 2017 and December 31, 2016, our deferred expenses classified as other long-term assets were $48.2 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:

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. 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 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 now expanded our population and are reviewing our contracts in order to quantify the consolidated impact of such changes. At this time, we expect to apply the modified retrospective approach during the first quarter of 2018. However, we are still evaluating the requirements to determine the impact of the adoption on our 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. 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 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

(2) Adjusted operating income (loss) is computed by subtracting the sum of direct costs, general and administrative expenses, research and engineering expenses and depreciation and amortization from operating revenues. Management evaluates the performance of our operating segments using adjusted operating income (loss), which is a segment performance measure, because it believes that this financial measure reflects our ongoing profitability and performance. In addition, securities analysts and investors use this measure as one of the metrics on which they analyze our performance. A reconciliation to income (loss) from continuing operations before income taxes is provided in the above table.

Represents the elimination of inter-segment transactions and unallocated corporate expenses, assets and capital expenditures.
