Notes to Consolidated Financial Statements (Unaudited)

1. Basis of Presentation

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The accompanying unaudited consolidated financial statements of National Oilwell Varco, Inc. (“NOV” or the “Company”) present information in accordance with GAAP in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X. They do not include all information or footnotes required by GAAP in the United States for complete consolidated financial statements and should be read in conjunction with our 2017 Annual Report on Form 10-K.

In our opinion, the consolidated financial statements include all adjustments, which are of a normal recurring nature, unless otherwise disclosed, necessary for a fair presentation of the results for the interim periods. Certain reclassifications have been made to the prior year financial statements in order for them to conform with the current presentation. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase. See Note 7 for the fair value of long-term debt and Note 10 for the fair value of derivative financial instruments.

Warranties

The Company provides warranties on certain of its products and services. The Company accrues warranty liability based upon specific claims and a review of historical claim experience in accordance with Accounting Standards Codification (“ASC”) Topic 450 “Contingencies”. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered.

The changes in the warranty provision are as follows (in millions):

Balance at December 31, 2017	$	135

The Company’s reporting currency is the U.S. dollar. For a majority of the Company’s international entities in which there is a substantial investment, the local currency is their functional currency. As a result, currency translation adjustments resulting from the process of translating the entities’ financial statements into the reporting currency are reported in other comprehensive income or loss in accordance with ASC Topic 830 “Foreign Currency Matters” (“ASC Topic 830”). For the three months ended June 30, 2018, a majority of these local currencies weakened against the U.S. dollar resulting in net other comprehensive loss of $223 million, upon the translation from local currencies to the U.S. dollar. For the six months ended June 30, 2018, a majority of these local currencies weakened against the U.S. dollar resulting in net other comprehensive loss of $187 million, upon the translation from local currencies to the U.S. dollar. For the three months ended June 30, 2017, a majority of these local currencies strengthened against the U.S. dollar resulting in net other comprehensive income of $76 million, upon the translation from local currencies to the U.S. dollar. For the six months ended June 30, 2017, a majority of these local currencies strengthened against the U.S. dollar resulting in net other comprehensive income of $166 million upon the translation from local currencies to the U.S. dollar.

The effect of changes in the fair values of derivatives designated as cash flow hedges are accumulated in other comprehensive income or loss, net of tax, until the underlying transactions to which they are designed to hedge are realized. The movement in other comprehensive income or loss from period to period will be the result of the combination of changes in fair value for open derivatives and the outflow of other comprehensive income or loss related to cumulative changes in the fair value of derivatives that have settled in the current period. The accumulated effect was other comprehensive loss of $14 million (net of tax of $5 million) and $1 million (net of tax of $0) for the three and six months ended June 30, 2018, respectively. The accumulated effect was other comprehensive income of $23 million (net of tax of $6 million) and $28 million (net of tax of $7 million) for the three and six months ended June 30, 2017, respectively.

Rig Technologies		62			6			80			19
Eliminations and corporate costs		(88	)		(71	)		(135	)		(132	)
Total operating profit (loss)	$	52		$	(62	)	$	51		$	(159	)
Operating profit (loss)%:
Wellbore Technologies		4.8	%		(3.9	%)		3.3	%		(6.9	%)
Completion & Production Solutions		5.4	%		4.1	%		4.0	%		2.7	%
Rig Technologies		9.5	%		1.1	%		7.1	%		1.7	%
Total operating profit (loss)%		2.5	%		(3.5	%)		1.3	%		(4.5	%)

Sales from one segment to another generally are priced at estimated equivalent commercial selling prices; however, segments originating an external sale are credited with the full profit to the Company. Eliminations include intercompany transactions conducted between the three reporting segments that are eliminated in consolidation. Intercompany transactions within each reporting segment are eliminated within each reporting segment.

Included in operating profit (loss) are other items primarily related to costs associated with severance, facility closures, and credits for the reversals of certain accruals.

6. Revenue Recognition

The Company’s products and services are sold based upon purchase orders or contracts with customers that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The majority of our revenue streams record revenue at a point in time when a performance obligation has been satisfied by transferring control of promised goods or services to the customer. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.    

Payment terms and conditions vary by contract type. In instances where the timing of revenue recognition differs from the timing of invoicing on contracts with a duration of one year or longer, we have determined our contracts generally do not include a significant financing component, as they are structured to include progress billings commensurate with revenue recognized over time. We have elected to apply the practical expedient that does not require an adjustment for a significant financing component if, at contract inception, the period between when we transfer the promised goods or service to the customer and when the customer pays for the goods or service is one year or less.

The Company elects to treat shipping and handling costs as costs to fulfill a performance obligation instead of as a separate performance obligation. We recognize the cost for shipping and handling when incurred, generally when control over the products has transferred to the customer, as an expense in cost of sales.

9

Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. We take into consideration the degree of integration of the related products and services, the level of customization of the product for the customer, and the interdependency of the products and services.

Judgment is also required to determine the stand-alone selling price (“SSP”) for each distinct performance obligation. To determine the SSP, the Company uses the price at which the products and services would be sold separately to the customer. We also review past sales transactions to confirm invoice prices for each distinct performance obligation reasonably approximate SSP and that there are no significant deviations. A discount, when provided, is also allocated based on the relative SSP of the various products and services.

We may provide other credits or incentives, which are accounted for as variable consideration when determining the transaction price. These credits or incentives are estimated at contract inception and updated at the end of each reporting period as additional information becomes available and recognized only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

For revenue that is not recognized at a point in time, the Company follows accounting guidance for revenue recognized over time, as follows:

Revenue Recognition under Long-term Construction Contracts

The Company uses the over-time method to account for certain long-term construction contracts in the Completion & Production Solutions and Rig Technologies segments. These long-term construction contracts include the following characteristics:

• the contracts include custom designs for customer specific applications;

• the structural design is unique and requires significant engineering efforts; and

• the Company has an enforceable right to payment for performance completed to date including a reasonable profit.

Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost (input) measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials and subcontractors’ costs, and other direct costs. If estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined.

For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability. Hence, the entire contract is accounted for as one performance obligation.

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. It is common for our long-term contracts to contain late delivery fees, work performance guarantees, and other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the most likely amount to which we expect to pay or be entitled to. We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. Net revenue recognized from our performance obligations satisfied in previous periods was $47 million for the six months ended June 30, 2018 primarily due to change orders.

Service and Repair Work

For those contracts in which we are providing a service to the customer, the output method is utilized to measure progress due to the manner in which the customer receives and derives value from the services being provided. For repair contracts, we generally use the cost-to-cost measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts.

10

Remaining Performance Obligations

Remaining performance obligations represents the transaction price of firm orders for all revenue streams for which work has not been performed on contracts with an original expected duration of one year or more. The optional disclosures for the remaining performance obligations of royalty contracts, service contracts for which there is a right to invoice, and short-term contracts that are expected to have a duration of one year or less have not been disclosed.

As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $2,610 million. The Company expects to recognize approximately $775 million in revenue for the remaining performance obligations in 2018 and $1,835 million in 2019 and thereafter.

Costs to Obtain and Fulfill a Contract

We recognize an asset for the incremental costs of obtaining a contract, such as sales commissions, with a customer when we expect the benefit of those costs to be longer than one year. Costs to fulfill a contract, such as set-up and mobilization costs, are also capitalized when we expect to recover those costs. These contract costs are deferred and amortized over the period of contract performance. Total capitalized costs to obtain and fulfill a contract and the related amortization were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets.

We apply the practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.

Disaggregation of Revenue

The following tables disaggregate our revenue by destinations, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. In the tables below, North America includes only the U.S. and Canada. (in millions):

Contract Assets and Liabilities

Contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not only subject to the passage of time. There were no impairment losses recorded on contract assets for the periods ending June 30, 2018 or 2017.

Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. For the balance at December 31, 2017, we reclassified $240 million of advance payments and deferred revenue from accrued liabilities to contract liabilities to conform with the 2018 presentation.

The changes in the carrying amount of contract assets and contract liabilities are as follows (in millions):

Contract Assets
Balance at December 31, 2017	$	495
Additions and Milestone Billings		(456	)
Revenue Recognized		500

Long-term debt	$	2,707	$	2,706

The Company has a $3.0 billion, five-year unsecured revolving credit facility, which expires on June 27, 2022. The Company has the right to increase the aggregate commitments under this agreement to an aggregate amount of up to $4.0 billion upon the consent of only those lenders holding any such increase. Interest under the multicurrency facility is based upon LIBOR, NIBOR or CDOR plus 1.125% subject to a ratings-based grid or the U.S. prime rate. The credit facility contains a financial covenant regarding maximum debt-to-capitalization ratio of 60%. As of June 30, 2018, the Company was in compliance with a debt-to-capitalization ratio of 16.3%.

The Company has a commercial paper program under which borrowings are classified as long-term since the program is supported by the $3.0 billion, five-year credit facility. At June 30, 2018, there were no commercial paper borrowings, and there were no outstanding letters of credit issued under the credit facility, resulting in $3.0 billion of funds available under this credit facility.

The Company had $511 million of outstanding letters of credit at June 30, 2018, primarily in the U.S. and Norway, that are under various bilateral letter of credit facilities. Letters of credit are issued as bid bonds, advanced payment bonds and performance bonds.

At June 30, 2018 and December 31, 2017, the fair value of the Company’s unsecured Senior Notes approximated $2,266 million and $2,346 million, respectively. The fair value of the Company’s debt is estimated using Level 2 inputs in the fair value hierarchy and is based on quoted prices for those or similar instruments. At June 30, 2018 and December 31, 2017, the carrying value of the Company’s unsecured Senior Notes approximated $2,481 million and $2,480 million, respectively.

8. Income Taxes

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018. At June 30, 2018 and December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we made reasonable estimates of the effects and recorded provisional amounts. We will continue to make and refine our calculations as additional analysis is completed. We recognized an income tax benefit of $242 million in the year ended December 31, 2017 associated with the revaluation of our net deferred tax liability. Our provisional estimate of the one-time transition tax resulted in no additional tax expense. Our provisional estimate on Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), and IRC Section 163(j) interest limitation do not impact our effective tax rate for the three and six months ended June 30, 2018. The accounting for the tax effects of the Act will be completed in 2018 as provided by the U.S. Securities and Exchange Commission’s SAB No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act.

The effective tax rates for the three and six months ended June 30, 2018 were 16.7% and (24.3)%, respectively, compared to 18.7% and 13.4% for the same periods in 2017. The Company established valuation allowances on deferred tax assets for losses and tax credits generated in each period, which, when applied to losses for the six months ended June 30, 2018 and the three and six months ended June 30, 2017, resulted in lower effective tax rates than the U.S. statutory rate. The negative tax rate for the six months ended June 30, 2018 is the result of net tax expense recorded against a pre-tax loss for the period. For the three months ended June 30, 2018, a reduction in tax reserves and utilization of tax credits were partially offset by valuation allowances established by the company, which, when applied to income resulted in a lower effective tax rate than the US statutory rate. The change in effective tax rate from 2017 to 2018 was also impacted by the decrease in the U.S. federal corporate tax rate from 35% in 2017 to 21% in 2018.

The balance of unrecognized tax benefits at June 30, 2018 was $57 million. The settlement of foreign jurisdiction audits during the year resulted in a $93 million decrease in uncertain tax positions.

For the three and six months ended June 30, 2018, the Company utilized the discrete-period method to compute its interim tax provision due to significant variations in the relationship between income tax expense and pre-tax accounting income or loss. For the three and six months ended June 30 2017, the Company estimated and recorded tax based on a full year effective tax rate.

9. Stock-Based Compensation

The Company has a stock-based compensation plan known as the National Oilwell Varco, Inc. Long-Term Incentive Plan (the “Plan”). The Plan provides for the granting of stock options, performance-based share awards, restricted stock, phantom shares, stock payments and stock appreciation rights (“SARs”). The number of shares authorized under the Plan is 69.4 million. The Plan is subject to a fungible ratio concept, such that the issuance of stock options and SARs reduces the number of available shares under the Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the Plan on a 3-for-1 basis. At June 30, 2018, 9,635,836 shares remain available for future grants under the Plan, all of which are available for grants of stock options, performance-based share awards, restricted stock awards, phantom shares, stock payments and SARs.

On February 28, 2018, the Company granted 1,610,599 stock options with a fair value of $10.01 per share and an exercise price of $35.09 per share; 2,391,933 shares of restricted stock and restricted stock units with a fair value of $35.09 per share; performance share awards to senior management employees with potential payouts varying from zero to 449,532 shares; and 14,228 SARs. The stock options vest over a three-year period from the grant date. The restricted stock and restricted stock units vest in three equal annual installments commencing on the first anniversary of the date of grant. The performance share awards can be earned based on performance against established goals over a three-year performance period. The performance share awards are based entirely on a TSR (total shareholder return) goal. Performance against the TSR goal is determined by comparing the performance of the Company’s TSR with the TSR performance of the members of the OSX index for the three-year performance period.

On May 11, 2018, the Company granted 35,432 restricted stock awards with a fair value of $40.65 per share. The awards were granted to non-employee members of the board of directors and vest on the first anniversary of the grant date.

Total stock-based compensation for all stock-based compensation arrangements under the Plan was $31 million and $58 million for the three and six months ended June 30, 2018, respectively, and $22 million and $52 million for the three and six months ended June 30, 2017, respectively. The total income tax benefit recognized in the Consolidated Statements of Income (Loss) for all stock-based compensation arrangements under the Plan was $4 million and $6 million for the three and six months ended June 30, 2018, respectively, and $5 million and $9 million for the three and six months ended June 30, 2017, respectively.

10. Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is foreign currency exchange rate risk. Forward contracts against various foreign currencies are entered into to manage the foreign currency exchange rate risk on forecasted revenues and expenses denominated in currencies other than the functional currency of the operating unit (cash flow hedge). In addition, the Company will enter into non-designated forward contracts against various foreign currencies to manage the foreign currency exchange rate risk on non-functional-currency monetary accounts (non-designated hedge).

The Company records all derivative financial instruments at their fair value in its Consolidated Balance Sheet. Except for certain non-designated hedges discussed below, all derivative financial instruments that the Company holds are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Such arrangements typically have terms between 2 and 24 months, but may have longer terms depending on the underlying cash flows being hedged, typically related to the projects in our backlog. The Company may also use interest rate contracts to mitigate its exposure to changes in interest rates on anticipated long-term debt issuances.

At June 30, 2018, the Company has determined that the fair value of its derivative financial instruments representing assets of $21 million and liabilities of $15 million (primarily currency related derivatives) are determined using level 2 inputs (inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability) in the fair value hierarchy as the fair value is based on publicly available foreign exchange and interest rates at each financial reporting date. At June 30, 2018, the net fair value of the Company’s foreign currency forward contracts totaled a net asset of $6 million.

At June 30, 2018, the Company did not have any interest rate contracts and its financial instruments do not contain any credit-risk-related or other contingent features that could cause accelerated payments when the Company’s financial instruments are in net liability positions. We do not use derivative financial instruments for trading or speculative purposes.

Cash Flow Hedging Strategy

To protect against the volatility of forecasted foreign currency cash flows resulting from forecasted revenues and expenses, the Company has instituted a cash flow hedging program. The Company hedges portions of its forecasted revenues and expenses denominated in non-functional currencies with forward contracts. When the U.S. dollar strengthens or weakens against the foreign currencies, the change in present value of future foreign currency revenues and expenses is offset by changes in the fair value of the forward contracts designated as hedges.

For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is subject to a particular currency risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings (e.g., in “revenues” when the hedged transactions are cash flows associated with forecasted revenues). The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), or hedge components excluded from the assessment of effectiveness, is recognized in the Consolidated Statements of Loss during the current period.

For the six months ended June 30, 2018, the Company recognized a gain of $2 million as a result of the discontinuance of certain cash flow hedges when it became probable that the original forecasted transactions would not occur by the end of the originally specified time period. At June 30, 2018, there were $8 million in pre-tax losses recorded in accumulated other comprehensive income (loss). Significant changes in forecasted operating levels or delays in large capital construction projects, whereby certain hedged transactions associated with these projects are no longer probable of occurring by the end of the originally specified time period, could result in losses or gains due to the de-designation of existing hedge contracts.

Non-designated Hedging Strategy

The Company enters into foreign currency forward contracts to hedge certain nonfunctional currency monetary accounts. The purpose of the Company’s foreign currency hedging activities is to protect the Company from risk that the eventual U.S. dollar equivalent cash flows from the non-functional currency monetary accounts will be adversely affected by changes in the exchange rates.

For derivative instruments that are non-designated, the gain or loss on the derivative instrument subject to the hedged risk (i.e., non-functional currency monetary accounts) is recognized in other income (expense), net in current earnings.

Cash dividends per share	$	0.05	$	0.05		$	0.10		$	0.10

ASC Topic 260, “Earnings Per Share” requires companies with unvested participating securities to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method requires a portion of net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income (loss) attributable to Company allocated to these participating securities was immaterial for the three and six months ended June 30, 2018 and 2017 and therefore not excluded from net income attributable to Company per share calculation.

The Company had stock options outstanding that were anti-dilutive totaling 18 million for each of the three and six months ended June 30, 2018, and 18 million shares and 13 million shares for each of the three and six months ended June 30, 2017, respectively.

12. Cash Dividends

On May 11, 2018, the Company’s Board of Directors approved a cash dividend of $0.05 per share. The cash dividend was paid on June 29, 2018, to each stockholder of record on June 15, 2018. Cash dividends were $19 million and $38 million for the three and six months ended June 30, 2018, respectively, and $19 million and $38 million for the three and six months ended June 30, 2017. The declaration and payment of future dividends is at the discretion of the Company’s Board of Directors and will be dependent upon the Company’s results of operations, financial condition, capital requirements and other factors deemed relevant by the Company’s Board of Directors.

13. Commitments and Contingencies

Our business is affected both directly and indirectly by governmental laws and regulations relating to the oilfield service industry in general, as well as by environmental and safety regulations that specifically apply to our business. Our business is also subject to trade regulations that may restrict or prohibit trade with certain countries, companies and/or individuals, such as trade sanctions applicable, for example, to Russia, Syria and Iran. Although we have not incurred material costs in connection with our compliance with such laws, there can be no assurance that other developments, such as new environmental laws, regulations and enforcement policies may not result in additional, presently unquantifiable, costs or liabilities to us. We are also subject to increasing local content and localization requirements in various jurisdictions, as well as increasing trade tariffs, retaliatory tariffs and other trade controversies, all of which could result in material negative impacts to our business.

The Company is involved in various claims, internal investigations, regulatory agency audits and pending or threatened legal actions, arbitration, litigation, and regulatory investigations, involving a variety of matters. In many instances, the Company maintains insurance that covers claims arising from risks associated with the business activities of the Company, including claims for injuries to third parties and third parties’ property, e.g., premises liability, product liability and other such claims. The Company carries substantial insurance to cover such risks above a self-insured retention. The Company believes and the Company’s experience has been that such insurance has been sufficient to cover such risks. See Item 1A. Risk Factors. If, however, such insurance were inapplicable or insufficient to cover such losses, there could be material negative impacts to our business.

The Company is also a party to claims, threatened and actual litigation, governmental regulatory proceedings and private arbitration arising from ordinary day to day business activities, in which parties assert claims against the Company for a broad spectrum of potential liabilities, including: individual employment law claims, collective actions under federal employment laws, intellectual property claims, e.g., alleged patent infringement, and/or misappropriation of trade secrets, premises liability claims, personal injuries arising from allegedly defective products, alleged improper payments under anti-corruption and anti-bribery laws and other commercial claims seeking recovery for alleged actual or exemplary damages. In currently pending litigation and arbitrations, adverse parties have asserted damages in material amounts for which they seek recovery from the Company. Due to the inherent risks and uncertainty of litigation, an unexpected adverse result may occur from time to time. For many such contingent claims, the Company’s insurance coverage is inapplicable or an exclusion to coverage may apply. In such instances, settlement or other resolution of such contingent claims could have a material financial or reputational impact on the Company.

As of June 30, 2018, the Company recorded reserves in an amount believed to be sufficient for contingent liabilities representing all contingencies believed to be probable to cover such liabilities. The Company has also assessed the potential for additional losses above the amounts accrued as well as potential losses for matters that are not probable but are reasonably possible. The total potential loss on these matters cannot be determined; however, in our opinion, any ultimate liability, to the extent not otherwise provided for and except for the specific cases referred to above, will not materially affect our financial position, cash flow or results of operations. These estimated liabilities are based on the Company’s assessment of the nature of these matters, their progress toward resolution, the advice of legal counsel and outside experts as well as management’s intention and experience.

Further, in some instances, direct or indirect consumers of our products and services, entities providing financing for purchases of our products and services or members of the supply chain for our products and services have become involved in governmental investigations, internal investigations, political or other enforcement matters. In such circumstances, such investigations may adversely impact the ability of consumers of our products, entities providing financial support to such consumers or entities in the supply chain to timely perform their business plans or to timely perform under agreements with us. We may also become involved in these investigations, at substantial cost to the Company.

14. New Accounting Pronouncements

Recently Adopted Accounting Standards

In March 2017, the FASB issued Accounting Standard Update No. 2017-07 “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (ASU 2017-07). This update requires that an employer report the service cost component in the same line item as other compensation costs and separately from other components of net benefit cost. ASU 2017-07 is effective for fiscal periods beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

In August 2016, the FASB issued Accounting Standard Update No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments” (ASU 2016-15). This update amends Accounting Standard Codification Topic No. 230 “Statement of Cash Flows” and provides guidance and clarification on presentation of certain cash flow issues. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

19

In May 2014, the FASB issued Accounting Standard Update No. 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU proscribes a five-step model for determining when and how revenue is recognized. Under the model, an entity will recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services.

ASU 2014-09 is effective for fiscal periods beginning after December 15, 2017. The Company adopted this update on January 1, 2018, using the modified retrospective approach, in which an immaterial cumulative effect adjustment was made to retained earnings. The adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the six months ended June 30, 2018. See Note 6 for additional details of the adoption of this standard.

Recently Issued Accounting Standards

In August 2017, the FASB issued Accounting Standard Update No. 2017-12 “Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities” (ASU 2017-12). This update improves the financial reporting of hedging relationships and simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective for fiscal periods beginning after December 15, 2018, and for interim periods within those fiscal years. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company is currently assessing the impact of the adoption of ASU No. 2017-12 on its consolidated financial position and results of operations.

In March 2016, the FASB issued ASC Topic 842, “Leases” (ASC Topic 842), which supersedes the lease requirements in ASC Topic No. 840 “Leases” and most industry-specific guidance. This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASC Topic 842 is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years.

In preparing for the adoption of this new standard, the Company has established an internal team to centralize the implementation process as well as engaged external resources to assist in our approach. We are currently utilizing a software program to consolidate and accumulate leases with documentation as required by the new standard. We have assessed the changes to the Company’s current accounting practices and are investigating the related tax impact and process changes. We are also in process of quantifying the impact of the new standard on our balance sheet.

Critical Accounting Policies and Estimates

In our annual report on Form 10-K for the year ended December 31, 2017, we identified our most critical accounting policies. In preparing the financial statements, we make assumptions, estimates and judgments that affect the amounts reported. We periodically evaluate our estimates and judgments that are most critical in nature which are related to revenue recognition (See Note 6 for new accounting policy on revenue recognition); allowance for doubtful accounts; inventory reserves; impairment of long-lived assets (excluding goodwill and other indefinite-lived intangible assets); goodwill and other indefinite-lived intangible assets; purchase price allocation of acquisitions; warranties; and income taxes. Our estimates are based on historical experience and on our future expectations that we believe are reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results are likely to differ from our current estimates and those differences may be material.

EXECUTIVE SUMMARY

For the second quarter ended June 30, 2018, the Company generated net income of $24 million, or $0.06 per fully diluted share, on $2.1 billion in revenue. For the first quarter ended March 31, 2018, the Company had a net loss of $68 million, or $0.18 per fully diluted share. For the second quarter of 2017, the Company had a net loss of $75 million, or $0.20 per fully diluted share.

Operating profit for the second quarter of 2018 was $52 million, or 2.5% of sales, compared to operating losses of $1 million in the first quarter of 2018 and $62 million in the second quarter of 2017.

During the second quarter of 2018, first quarter of 2018, and second quarter of 2017, pre-tax other items (severance, facility closures, write-downs of certain assets and liabilities, and other) were $0, a credit of $12 million, and expense of $30 million, respectively. Excluding the other items from all periods, second quarter 2018 Adjusted EBITDA was $226 million, compared to $160 million in the first quarter of 2018 and $142 million in the second quarter of 2017.

Oil & Gas Equipment and Services Market

Over the past decade, technological advancements in the oilfield equipment and service space unlocked production from formations that were previously deemed uneconomic, especially in North America. From 2004 to 2014 global oil and liquids supply increased dramatically from U.S. unconventional resources, deep-water (defined as water depths greater than 400 feet) resources and from other sources. The advances in technology combined with relatively high commodity prices caused by growing demand enabled and sustained an increase in global drilling activity. Global supply started to catch up to demand, and, in the latter half of 2014, demand growth in areas such as Asia, Europe and the U.S. weakened while drilling activity remained strong and production continued to grow. As a result, global inventories of crude and refined products grew and the price of oil declined significantly during early 2015, remaining depressed throughout the year and undergoing another major reduction toward the end of 2015. In early 2016, the market witnessed oil trading in the high $20 per barrel range, prices not seen since 2003.

In response to rapidly deteriorating market conditions, operators acutely reduced both operating and capital expenditures. Orders for NOV’s equipment and services slowed and rig counts declined rapidly with active U.S. drilling rig counts hitting 70 year lows, and international rig counts reaching decade lows, during the second quarter of 2016. As a result of the sharp cutback in activity, production declined in certain areas of the world, global inventories began to decline and commodity prices started to rebound as oil markets began to re-balance. The market downturn began to stabilize during the second half of 2016 and showed early signs of improvement as the year ended. During 2017 and into the first half of 2018, land drilling in North America continued to increase, while international markets stabilized and offshore activity remained depressed. The average price of West Texas Intermediate Cushing Crude for the second quarter of 2018 was $68.03 a barrel.

Segment Performance

Wellbore Technologies

Wellbore Technologies generated revenues of $793 million in the second quarter of 2018, an increase of 12 percent from the first quarter of 2018 and an increase of 29 percent from the second quarter of 2017. The ongoing recovery in the U.S. and seasonal rebound in the Eastern Hemisphere led to sequential growth across every business unit in the segment. Operating profit was $38 million, or 4.8 percent of sales. Adjusted EBITDA was $133 million, or 16.8 percent of sales, an increase of 29 percent sequentially and an increase of $67 million from the prior year.

Completion & Production Solutions

Completion & Production Solutions generated revenues of $738 million in the second quarter of 2018, an increase of 10 percent from the first quarter of 2018 and an increase of 13 percent from the second quarter of 2017. Improving demand for capital equipment in North America and an increase in deliveries of pressure pumping equipment and composite pipe more than offset lower revenues from offshore products. Operating profit was $40 million or 5.4 percent of sales. Adjusted EBITDA was $94 million, or 12.7 percent of sales, an increase of 29 percent sequentially and a decrease of four percent from the prior year.

Backlog for capital equipment orders for Completion & Production Solutions at June 30, 2018 was $955 million. New orders booked during the quarter were $398 million, representing a book-to-bill of 95 percent when compared to the $418 million of orders shipped from backlog.

23

Rig Technologies

Rig Technologies generated revenues of $651 million in the second quarter of 2018, an increase of 35 percent from the first quarter of 2018 and an increase of 19 percent from the second quarter of 2017. The sequential increase in revenue was the result of better progress on the construction of offshore newbuild drilling rigs and improving aftermarket sales. Operating profit was $62 million, or 9.5 percent of sales. Adjusted EBITDA was $84 million, or 12.9 percent of sales, an increase of 87 percent sequentially and an increase of 83 percent from the prior year.

Backlog for capital equipment orders for Rig Technologies at June 30, 2018 was $3.5 billion. Net new orders booked during the quarter totaled $2.03 billion, which included $1.80 billion associated with the Company’s recently announced joint venture agreement with Saudi Aramco.

Outlook

Activity in North America increased sharply off historical lows during the last two quarters of 2016 and through 2017. The second quarter of 2018 saw the US working land rig count continue to improve. Declines in supply appear to have rebalanced the market and commodity prices and global activity levels have shown modest improvements, although challenging conditions persist for offshore work. Consequently, the Company anticipates that its offshore customers will continue to moderate capital expenditures, while land customers increase spending on NOV’s services and equipment to support higher levels of activity.

While North America land drilling has increased, working rig-counts remain well below prior cyclical highs. International land drilling, which had been slower to fall than North American activity, may have reached the bottom of its cycle during 2017, and is showing some signs of recovery. Offshore activity, which has longer project cycle times and, in certain instances, more challenged economics, may remain depressed during 2018.

Low activity levels result in an oversupply of service capacity and capital equipment, creating challenging prospects for many of NOV’s customers and reducing demand for the Company’s products. In this environment, contractors have been hesitant to invest in their existing equipment to conserve as much capital as possible. Equipment has been neglected and idle fleets have been stripped of parts to sustain assets that remain active. Additionally, certain equipment becomes less desirable and obsolete as equipment manufacturers develop new technologies and produce more efficient equipment that improves efficiencies and lowers the marginal cost of supply for oil and gas operating companies. The Company believes that the sharp spending reductions its customers have had in place for an extended period created pent up demand for NOV’s products that began to show in certain areas during the second half of 2017 as industry activity levels began to improve. The areas in which the Company is seeing improving demand continued to expand as the early stages of the industry’s recovery advanced through the first half of 2018.

NOV’s global customer base includes national oil companies, international oil companies, independent oil and gas companies, onshore and offshore service companies and others whose strategies and reactions to low commodity prices vary. Likewise, the Company expects the timing and slope of revenue stabilization and recovery will be different across its operating regions and its three business segments. NOV’s Wellbore Technologies segment and certain elements of its Completion & Production Solutions and Rig Technologies segments are realizing a faster recovery as drilling of new wells increases, while a strong recovery for certain of its more capital equipment oriented businesses are expected to come later in the cycle.

NOV will continue to adjust the size of its operations to fit anticipated levels of activity while investing in developing and acquiring new products, technologies and operations that advance the Company’s longer term strategic goals. NOV has a history of implementing cost-control measures and downsizing in response to depressed market conditions as well as cost effectively ramping operations to capitalize on rapidly increasing demand. The Company has closed, or is in the process of closing, 420 locations over the past three years. It has reduced its annual expenses relating to salaries, wages, outside services, contractors, travel and entertainment by approximately $3.0 billion. The Company remains optimistic regarding longer-term market fundamentals as existing oil and gas fields continue to deplete and numerous major projects to replenish supply have been deferred or canceled while global demand continues to grow.

Though the Company benefited from a high concentration of orders for offshore drilling equipment and services in the preceding years, significant contraction in the offshore market during the recent downturn adversely effected the Company’s performance. Offshore market dynamics and equipment oversupply are expected to cause slower recovery there than in our land business, however, it is in NOV’s strategic interest to maintain a leading position in offshore drilling equipment. The Company has intentionally and successfully pivoted towards onshore and non-drilling related activities in recent years, highly responsive to the industry’s increased focus on onshore unconventional developments. Approximately 65% of consolidated revenues were derived from onshore businesses during the second quarter of 2018, compared to approximately 40% in 2014.

24

NOV expects unconventional resources to continue to gain a greater share of global production, and the Company will continue to enhance its offering into unconventional resource focused products and technologies, including advanced, automated drilling rigs; premium drillpipe and directional drilling technologies; hydraulic fracture stimulation equipment; and multistage completion tools. NOV expects big data and predictive analytics to improve uptime and operating efficiency, and the Company remains at the forefront of applying this promising technology to oilfield drilling and completion equipment. NOV expects the oil and gas industry to adopt more efficient supply chain practices that the Company is pioneering to construct floating production facilities to produce the immense resources discovered offshore. The Company has used the recent downturn to vigorously advance these strategic initiatives, and is encouraged by its progress.

Wellbore Technologies

Three and six months ended June 30, 2018 and 2017. Revenue from Wellbore Technologies was $793 million for the three months ended June 30, 2018, compared to $614 million for the three months ended June 30, 2017, an increase of $179 million or 29%. For the six months ended June 30, 2018, revenue from Wellbore Technologies was $1,504 million compared to $1,169 million for the six months ending June 30, 2017, an increase of $335 million or 29%.

Operating profit (loss) from Wellbore Technologies was $38 million for the three months ended June 30, 2018 compared to $(24) million for the three months ended June 30, 2017, an increase of $62 million. For the six months ended June 30, 2018, operating profit (loss) from Wellbore Technologies was $50 million compared to $(81) million for the six months ending June 30, 2017, an increase of $131 million. Operating profit (loss) percentage increased to 3.3% for the six months ended June 30, 2018, from (6.9)% in the six months ended June 30, 2017. This increase was primarily due to the ongoing U.S. recovery.

Completion & Production Solutions

Three and six months ended June 30, 2018 and 2017. Revenue from Completion & Production Solutions was $738 million for the three months ended June 30, 2018, compared to $652 million for the three months ended June 30, 2017, an increase of $86 million or 13%. For the six months ended June 30, 2018, revenue from revenue from Completion & Production Solutions was $1,408 million compared to $1,300 million for the six months ending June 30, 2017, an increase of $108 million or eight percent.

Operating profit from Completion & Production Solutions was $40 million for the three months ended June 30, 2018 compared to $27 million for the three months ended June 30, 2017, an increase of $13 million or 48%. For the six months ended June 30, 2018, operating profit from Completion and Production Solutions was $56 million compared to $35 million for the six months ending June 30, 2017, an increase of $21 million or 60%. Operating profit percentage increased to 4.0% for the six months ended June 30, 2018, from 2.7% in the six months ended June 30, 2017. Improved demand for capital equipment in North America and an increase in deliveries of pressure pumping equipment and composite pipe more than offset lower demand for offshore products.

The Completion & Productions Solutions segment monitors its capital equipment backlog to plan its business. New orders are added to backlog only when the Company receives a firm written order for major completion and production components or a signed contract related to a construction project. The capital equipment backlog was $955 million at June 30, 2018, an increase of $74 million, or eight

27

percent from backlog of $881 million at June 30, 2017. Numerous factors may affect the timing of revenue out of backlog. Considering these factors, the Company reasonably expects approximately $733 million of revenue out of backlog for the remainder of 2018 and approximately $222 million of revenue out of backlog in 2019 and thereafter. At June 30, 2018, approximately 56% of the capital equipment backlog was for offshore products and approximately 64% of the capital equipment backlog was destined for international markets.

Rig Technologies

Three months and six ended June 30, 2018 and 2017. Revenue from Rig Technologies was $651 million for the three months ended June 30, 2018, compared to $546 million for the three months ended June 30, 2017, an increase of $105 million or 19%. For the six months ended June 30, 2018, revenue from Rig Technologies was $1,134 million compared to $1,128 million for the six months ending June 30, 2017, an increase of $6 million or one percent.

Operating profit from Rig Technologies was $62 million for the three months ended June 30, 2018 compared to $6 million for the three months ended June 30, 2017, an increase of $56 million. For the six months ended June 30, 2018, operating profit from Rig Technologies was $80 million compared to $19 million for the six months ending June 30, 2017, an increase of $61 million. Operating profit percentage increased to 7.1% for the six months ended June 30, 2018, from 1.7% in the six months ended June 30, 2017. This increase was the result of better progress on the construction of offshore newbuild drilling rigs and improving aftermarket sales.

The Rig Technologies segment monitors its capital equipment backlog to plan its business. New orders are added to backlog only when the Company receives a firm written order for major drilling rig components or a signed contract related to a construction project. The capital equipment backlog was $3.51 billion at June 30, 2018, an increase of $1.29 billion, or 58%, from backlog of $2.22 billion at June 30, 2017. Numerous factors may affect the timing of revenue out of backlog. Considering these factors, the Company reasonably expects approximately $587 million of revenue out of backlog for the remainder of 2018 and approximately $2.93 billion of revenue out of backlog in 2019 and thereafter. At June 30, 2018, approximately 65% of the capital equipment backlog was for land products and approximately 90% of the capital equipment backlog was destined for international markets.

Eliminations and corporate costs

Eliminations and corporate costs were $88 million and $71 million for the three months ended June 30, 2018 and 2017, respectively. This change is primarily due to the change in intersegment eliminations. Sales from one segment to another generally are priced at estimated equivalent commercial selling prices; however, segments originating an external sale are credited with the full profit to the company. Eliminations include intercompany transactions conducted between the three reporting segments that are eliminated in consolidation. Intercompany transactions within each reporting segment are eliminated within each reporting segment.

Other income (expense), net

Other income (expense), net were expenses of $(3) million and $(50) million for the three and six months ended June 30, 2018, respectively, compared to expenses of $(5) million and $(20) million for the three and six months ended June 30, 2017, respectively. The change in expense was primarily due to the fluctuations in foreign currencies.

Provision for income taxes

The effective tax rates for the three and six months ended June 30, 2018 were 16.7% and (24.3)%, respectively, compared to 18.7% and 13.4% for the same periods in 2017. The Company established valuation allowances on deferred tax assets for losses and tax credits generated in each period, which, when applied to losses for the six months ended June 30, 2018 and the three and six months ended June 30, 2017, resulted in lower effective tax rates than the U.S. statutory rate. The negative tax rate for the six months ended June 30, 2018 is the result of net tax expense recorded against a pre-tax loss for the period. For the three months ended June 30, 2018, a reduction in tax reserves and utilization of tax credits were partially offset by valuation allowances established by the company, which, when applied to income resulted in a lower effective tax rate than the US statutory rate. The change in effective tax rate from 2017 to 2018 was also impacted by the decrease in the U.S. federal corporate tax rate from 35% in 2017 to 21% in 2018.

Liquidity and Capital Resources

Overview

The Company assesses liquidity in terms of its ability to generate cash to fund operating, investing and financing activities. The Company remains in a strong financial position, with resources available to reinvest in existing businesses, strategic acquisitions and capital expenditures to meet short- and long-term objectives. The Company believes that cash on hand, cash generated from expected results of operations, amounts available under its credit facility and its commercial paper program will be sufficient to fund operations, anticipated working capital needs and other cash requirements such as capital expenditures, debt and interest payments and dividend payments for the foreseeable future.

At June 30, 2018, the Company had cash and cash equivalents of $1,137 million and total debt of $2,715 million. At December 31, 2017, cash and cash equivalents were $1,437 million and total debt was $2,712 million. As of June 30, 2018, approximately $859 million of the $1,137 million of cash and cash equivalents was held by our foreign subsidiaries and the earnings associated with this cash were subject to U.S. taxation under the Act defined in Note 8 to the Consolidated Financial Statements. If opportunities to invest in the U.S. are greater than available cash balances that are not subject to income tax, rather than repatriating cash, the Company may choose to borrow against its revolving credit facility or utilize its commercial paper program.

The Company’s outstanding debt at June 30, 2018 was $2,715 million and consisted of $1,393 million in 2.60% Senior Notes, $1,088 million in 3.95% Senior Notes, and other debt of $234 million. The Company was in compliance with all covenants at June 30, 2018.

At June 30, 2018, there were no commercial paper borrowings, and there were no outstanding letters of credit issued under the credit facility, resulting in $3.0 billion of funds available under this credit facility.

The Company had $511 million of outstanding letters of credit at June 30, 2018, primarily in the U.S. and Norway, that are under various bilateral letter of credit facilities. Letters of credit are issued as bid bonds, advanced payment bonds and performance bonds.

The following table summarizes our net cash provided by continuing operating activities, continuing investing activities and continuing financing activities for the periods presented (in millions):

	Six Months Ended June 30,
	2018			2017
Net cash provided by operating activities	$	110		$	279
Net cash used in investing activities		(360	)		(148	)
Net cash used in financing activities		(20	)		(31	)

Operating Activities

For the first six months of 2018, cash provided by operating activities was $110 million compared to $279 million in the same period of 2017. Before changes in operating assets and liabilities, net of acquisitions, cash was provided primarily by net loss from operations of $41 million plus non-cash charges of $437 million.

The change in operating assets and liabilities in the first six months of 2018 compared to the same period in 2017 was primarily due to inventory and accrued liabilities. Net changes in operating assets and liabilities, net of acquisitions, used $286 million of cash for the first six months of 2018 compared to cash provided of $13 million in the same period in 2017.

From time to time, we participate in factoring arrangements to sell accounts receivable to third-party financial institutions. In the first six months of 2018, we sold accounts receivable of $187 million at a cost of approximately $1 million. We received cash proceeds totaling $186 million. Our factoring transactions in the first six months of 2018 were recognized as sales, and the proceeds are included as operating cash flows in our Condensed Consolidated Statements of Cash Flows.

30

Investing Activities

For the first six months of 2018, net cash used in investing activities was $360 million compared to $148 million for the same period of 2017. Net cash used in investing activities was primarily the result of capital expenditures and acquisition activity. The Company used $280 million during the first six months of 2018 for acquisitions compared to $82 million for the same period of 2017 and $102 million for capital expenditures in the first six months of 2018 compared to $85 million for the same period of 2017.

Financing Activities

For the first six months of 2018, net cash used in financing activities was $20 million compared to $31 million for the same period of 2017. This decrease was primarily the result of activity under stock incentive plans providing $22 million of cash in 2018 compared to $10 million in 2017. Dividends paid were $38 million for each of the first six months of 2018 and 2017, respectively.

Other

The effect of the change in exchange rates on cash flows was a decrease of $30 million and an increase of $22 million for the first six months of 2018 and 2017, respectively.

We believe that cash on hand, cash generated from operations and amounts available under our credit facilities and from other sources of debt will be sufficient to fund operations, working capital needs, capital expenditure requirements, dividends and financing obligations.

We intend to pursue additional acquisition candidates, but the timing, size or success of any acquisition effort and the related potential capital commitments cannot be predicted. We continue to expect to fund future cash acquisitions primarily with cash flow from operations and borrowings, including the unborrowed portion of the revolving credit facility or new debt issuances, but may also issue additional equity either directly or in connection with acquisitions. There can be no assurance that additional financing for acquisitions will be available at terms acceptable to us.

New Accounting Pronouncements

Recently Adopted Accounting Standards

In March 2017, the FASB issued Accounting Standard Update No. 2017-07 “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (ASU 2017-07). This update requires that an employer report the service cost component in the same line item as other compensation costs and separately from other components of net benefit cost. ASU 2017-07 is effective for fiscal periods beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

In August 2016, the FASB issued Accounting Standard Update No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments” (ASU 2016-15). This update amends Accounting Standard Codification Topic No. 230 “Statement of Cash Flows” and provides guidance and clarification on presentation of certain cash flow issues. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

In May 2014, the FASB issued Accounting Standard Update No. 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU proscribes a five-step model for determining when and how revenue is recognized. Under the model, an entity will recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services.

ASU 2014-09 is effective for fiscal periods beginning after December 15, 2017. The Company adopted this update on January 1, 2018, using the modified retrospective approach, in which an immaterial cumulative effect adjustment was made to retained earnings. The adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the three and six months ended June 30, 2018. See Note 6 for additional details of the adoption of this standard.

Recently Issued Accounting Standards

In August 2017, the FASB issued Accounting Standard Update No. 2017-12 “Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities” (ASU 2017-12). This update improves the financial reporting of hedging relationships and simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective for fiscal periods beginning after December 15, 2018, and for interim periods within those fiscal years. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company is currently assessing the impact of the adoption of ASU No. 2017-12 on its consolidated financial position and results of operations.

In March 2016, the FASB issued ASC Topic 842, “Leases” (ASC Topic 842), which supersedes the lease requirements in ASC Topic No. 840 “Leases” and most industry-specific guidance. This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASC Topic 842 is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years.

In preparing for the adoption of this new standard, the Company has established an internal team to centralize the implementation process as well as engaged external resources to assist in our approach. We are currently utilizing a software program to consolidate and accumulate leases with documentation as required by the new standard. We have assessed the changes to the Company’s current accounting practices and are investigating the related tax impact and process changes. We are also in process of quantifying the impact of the new standard on our balance sheet.

Forward-Looking Statements

Some of the information in this document contains, or has incorporated by reference, forward-looking statements. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements typically are identified by use of terms such as “may,” “expect,” “anticipate,” “estimate,” and similar words, although some forward-looking statements are expressed differently. All statements herein regarding expected merger synergies are forward-looking statements. You should be aware that our actual results could differ materially from results anticipated in the forward-looking statements due to a number of factors, including but not limited to changes in oil and gas prices, customer demand for our products, difficulties encountered in integrating mergers and acquisitions, and worldwide economic activity. You should also consider carefully the statements under “Risk Factors,” as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2017, which address additional factors that could cause our actual results to differ from those set forth in the forward-looking statements. Given these uncertainties, current or prospective investors are cautioned not to place undue reliance on any such forward-looking statements. We undertake no obligation to update any such factors or forward-looking statements to reflect future events or developments.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to changes in foreign currency exchange rates and interest rates. Additional information concerning each of these matters follows:

Foreign Currency Exchange Rates

We have extensive operations in foreign countries. The net assets and liabilities of these operations are exposed to changes in foreign currency exchange rates, although such fluctuations generally do not affect income since their functional currency is typically the local currency. These operations also have net assets and liabilities not denominated in the functional currency, which exposes us to changes in foreign currency exchange rates that impact income. We recorded a foreign exchange loss in our income statement of approximately $19 million in the first six months of 2018, compared to approximately $2 million in foreign exchange loss in the same period of the prior year. The gains and losses are primarily due to exchange rate fluctuations related to monetary asset balances denominated in currencies other than the functional currency and adjustments to our hedged positions as a result of changes in foreign currency exchange rates. Currency exchange rate fluctuations may create losses in future periods to the extent we maintain net monetary assets and liabilities not denominated in the functional currency of the countries using the local currency as their functional currency.

Some of our revenues in foreign countries are denominated in U.S. dollars, and therefore, changes in foreign currency exchange rates impact our earnings to the extent that costs associated with those U.S. dollar revenues are denominated in the local currency. Similarly, some of our revenues are denominated in foreign currencies, but have associated U.S. dollar costs, which also give rise to foreign currency exchange rate exposure. In order to mitigate that risk, we may utilize foreign currency forward contracts to better match the currency of our revenues and associated costs. We do not use foreign currency forward contracts for trading or speculative purposes.

The Company had other financial market risk sensitive instruments denominated in foreign currencies for transactional exposures totaling $103 million and translation exposures totaling $198 million as of June 30, 2018 excluding trade receivables and payables, which approximate fair value. These market risk sensitive instruments consisted of cash balances and overdraft facilities. The Company estimates that a hypothetical 10% movement of all applicable foreign currency exchange rates on the transactional exposures financial market risk sensitive instruments could affect net income by $7 million and the translational exposures financial market risk sensitive instruments could affect the future fair value by $20 million.

The counterparties to forward contracts are major financial institutions. The credit ratings and concentration of risk of these financial institutions are monitored on a continuing basis. In the event that the counterparties fail to meet the terms of a foreign currency contract, our exposure is limited to the foreign currency rate differential.

Interest Rate Risk

At June 30, 2018, long term borrowings consisted $1,393 million in 2.60% Senior Notes and $1,088 million in 3.95% Senior Notes. At June 30, 2018, there were no commercial paper borrowings and no outstanding letters of credit issued under the credit facility, resulting in $3.0 billion of funds available under this credit facility. Occasionally a portion of borrowings under our credit facility could be denominated in multiple currencies which could expose us to market risk with exchange rate movements. These instruments carry interest at a pre-agreed upon percentage point spread from either LIBOR, NIBOR or CDOR, or at the U.S. prime rate. Under our credit facility, we may, at our option, fix the interest rate for certain borrowings based on a spread over LIBOR, NIBOR or CDOR for 30 days to six months. Our objective is to maintain a portion of our debt in variable rate borrowings for the flexibility obtained regarding early repayment without penalties and lower overall cost as compared with fixed-rate borrowings.

Item 4. Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. The Company’s disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files under the Exchange Act is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures and is recorded, processed, summarized and reported within the time period specified in the rules and forms of the Securities and Exchange Commission. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective as of the end of the period covered by this report at a reasonable assurance level.

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1. Basis of Presentation

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The accompanying unaudited consolidated financial statements of National Oilwell Varco, Inc. (“NOV” or the “Company”) present information in accordance with GAAP in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X. They do not include all information or footnotes required by GAAP in the United States for complete consolidated financial statements and should be read in conjunction with our 2017 Annual Report on Form 10-K.

In our opinion, the consolidated financial statements include all adjustments, which are of a normal recurring nature, unless otherwise disclosed, necessary for a fair presentation of the results for the interim periods. Certain reclassifications have been made to the prior year financial statements in order for them to conform with the current presentation. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase. See Note 7 for the fair value of long-term debt and Note 10 for the fair value of derivative financial instruments.

Warranties

The Company provides warranties on certain of its products and services. The Company accrues warranty liability based upon specific claims and a review of historical claim experience in accordance with Accounting Standards Codification (“ASC”) Topic 450 “Contingencies”. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered.

The changes in the warranty provision are as follows (in millions):

The Company’s reporting currency is the U.S. dollar. For a majority of the Company’s international entities in which there is a substantial investment, the local currency is their functional currency. As a result, currency translation adjustments resulting from the process of translating the entities’ financial statements into the reporting currency are reported in other comprehensive income or loss in accordance with ASC Topic 830 “Foreign Currency Matters” (“ASC Topic 830”). For the three months ended June 30, 2018, a majority of these local currencies weakened against the U.S. dollar resulting in net other comprehensive loss of $223 million, upon the translation from local currencies to the U.S. dollar. For the six months ended June 30, 2018, a majority of these local currencies weakened against the U.S. dollar resulting in net other comprehensive loss of $187 million, upon the translation from local currencies to the U.S. dollar. For the three months ended June 30, 2017, a majority of these local currencies strengthened against the U.S. dollar resulting in net other comprehensive income of $76 million, upon the translation from local currencies to the U.S. dollar. For the six months ended June 30, 2017, a majority of these local currencies strengthened against the U.S. dollar resulting in net other comprehensive income of $166 million upon the translation from local currencies to the U.S. dollar.

The effect of changes in the fair values of derivatives designated as cash flow hedges are accumulated in other comprehensive income or loss, net of tax, until the underlying transactions to which they are designed to hedge are realized. The movement in other comprehensive income or loss from period to period will be the result of the combination of changes in fair value for open derivatives and the outflow of other comprehensive income or loss related to cumulative changes in the fair value of derivatives that have settled in the current period. The accumulated effect was other comprehensive loss of $14 million (net of tax of $5 million) and $1 million (net of tax of $0) for the three and six months ended June 30, 2018, respectively. The accumulated effect was other comprehensive income of $23 million (net of tax of $6 million) and $28 million (net of tax of $7 million) for the three and six months ended June 30, 2017, respectively.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

6. Revenue Recognition

The Company’s products and services are sold based upon purchase orders or contracts with customers that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The majority of our revenue streams record revenue at a point in time when a performance obligation has been satisfied by transferring control of promised goods or services to the customer. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.    

Payment terms and conditions vary by contract type. In instances where the timing of revenue recognition differs from the timing of invoicing on contracts with a duration of one year or longer, we have determined our contracts generally do not include a significant financing component, as they are structured to include progress billings commensurate with revenue recognized over time. We have elected to apply the practical expedient that does not require an adjustment for a significant financing component if, at contract inception, the period between when we transfer the promised goods or service to the customer and when the customer pays for the goods or service is one year or less.

The Company elects to treat shipping and handling costs as costs to fulfill a performance obligation instead of as a separate performance obligation. We recognize the cost for shipping and handling when incurred, generally when control over the products has transferred to the customer, as an expense in cost of sales.

Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. We take into consideration the degree of integration of the related products and services, the level of customization of the product for the customer, and the interdependency of the products and services.

Judgment is also required to determine the stand-alone selling price (“SSP”) for each distinct performance obligation. To determine the SSP, the Company uses the price at which the products and services would be sold separately to the customer. We also review past sales transactions to confirm invoice prices for each distinct performance obligation reasonably approximate SSP and that there are no significant deviations. A discount, when provided, is also allocated based on the relative SSP of the various products and services.

We may provide other credits or incentives, which are accounted for as variable consideration when determining the transaction price. These credits or incentives are estimated at contract inception and updated at the end of each reporting period as additional information becomes available and recognized only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

For revenue that is not recognized at a point in time, the Company follows accounting guidance for revenue recognized over time, as follows:

Revenue Recognition under Long-term Construction Contracts

The Company uses the over-time method to account for certain long-term construction contracts in the Completion & Production Solutions and Rig Technologies segments. These long-term construction contracts include the following characteristics:

• the contracts include custom designs for customer specific applications;

• the structural design is unique and requires significant engineering efforts; and

• the Company has an enforceable right to payment for performance completed to date including a reasonable profit.

Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost (input) measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials and subcontractors’ costs, and other direct costs. If estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined.

For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability. Hence, the entire contract is accounted for as one performance obligation.

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. It is common for our long-term contracts to contain late delivery fees, work performance guarantees, and other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the most likely amount to which we expect to pay or be entitled to. We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. Net revenue recognized from our performance obligations satisfied in previous periods was $47 million for the six months ended June 30, 2018 primarily due to change orders.

Service and Repair Work

For those contracts in which we are providing a service to the customer, the output method is utilized to measure progress due to the manner in which the customer receives and derives value from the services being provided. For repair contracts, we generally use the cost-to-cost measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts.

Remaining Performance Obligations

Remaining performance obligations represents the transaction price of firm orders for all revenue streams for which work has not been performed on contracts with an original expected duration of one year or more. The optional disclosures for the remaining performance obligations of royalty contracts, service contracts for which there is a right to invoice, and short-term contracts that are expected to have a duration of one year or less have not been disclosed.

As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $2,610 million. The Company expects to recognize approximately $775 million in revenue for the remaining performance obligations in 2018 and $1,835 million in 2019 and thereafter.

Costs to Obtain and Fulfill a Contract

We recognize an asset for the incremental costs of obtaining a contract, such as sales commissions, with a customer when we expect the benefit of those costs to be longer than one year. Costs to fulfill a contract, such as set-up and mobilization costs, are also capitalized when we expect to recover those costs. These contract costs are deferred and amortized over the period of contract performance. Total capitalized costs to obtain and fulfill a contract and the related amortization were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets.

We apply the practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.

Disaggregation of Revenue

The following tables disaggregate our revenue by destinations, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. In the tables below, North America includes only the U.S. and Canada. (in millions):

Contract Assets and Liabilities

Contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not only subject to the passage of time. There were no impairment losses recorded on contract assets for the periods ending June 30, 2018 or 2017.

Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. For the balance at December 31, 2017, we reclassified $240 million of advance payments and deferred revenue from accrued liabilities to contract liabilities to conform with the 2018 presentation.

Income Taxes

8. Income Taxes

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018. At June 30, 2018 and December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we made reasonable estimates of the effects and recorded provisional amounts. We will continue to make and refine our calculations as additional analysis is completed. We recognized an income tax benefit of $242 million in the year ended December 31, 2017 associated with the revaluation of our net deferred tax liability. Our provisional estimate of the one-time transition tax resulted in no additional tax expense. Our provisional estimate on Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), and IRC Section 163(j) interest limitation do not impact our effective tax rate for the three and six months ended June 30, 2018. The accounting for the tax effects of the Act will be completed in 2018 as provided by the U.S. Securities and Exchange Commission’s SAB No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act.

The effective tax rates for the three and six months ended June 30, 2018 were 16.7% and (24.3)%, respectively, compared to 18.7% and 13.4% for the same periods in 2017. The Company established valuation allowances on deferred tax assets for losses and tax credits generated in each period, which, when applied to losses for the six months ended June 30, 2018 and the three and six months ended June 30, 2017, resulted in lower effective tax rates than the U.S. statutory rate. The negative tax rate for the six months ended June 30, 2018 is the result of net tax expense recorded against a pre-tax loss for the period. For the three months ended June 30, 2018, a reduction in tax reserves and utilization of tax credits were partially offset by valuation allowances established by the company, which, when applied to income resulted in a lower effective tax rate than the US statutory rate. The change in effective tax rate from 2017 to 2018 was also impacted by the decrease in the U.S. federal corporate tax rate from 35% in 2017 to 21% in 2018.

The balance of unrecognized tax benefits at June 30, 2018 was $57 million. The settlement of foreign jurisdiction audits during the year resulted in a $93 million decrease in uncertain tax positions.

For the three and six months ended June 30, 2018, the Company utilized the discrete-period method to compute its interim tax provision due to significant variations in the relationship between income tax expense and pre-tax accounting income or loss. For the three and six months ended June 30 2017, the Company estimated and recorded tax based on a full year effective tax rate.

Stock-Based Compensation

9. Stock-Based Compensation

The Company has a stock-based compensation plan known as the National Oilwell Varco, Inc. Long-Term Incentive Plan (the “Plan”). The Plan provides for the granting of stock options, performance-based share awards, restricted stock, phantom shares, stock payments and stock appreciation rights (“SARs”). The number of shares authorized under the Plan is 69.4 million. The Plan is subject to a fungible ratio concept, such that the issuance of stock options and SARs reduces the number of available shares under the Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the Plan on a 3-for-1 basis. At June 30, 2018, 9,635,836 shares remain available for future grants under the Plan, all of which are available for grants of stock options, performance-based share awards, restricted stock awards, phantom shares, stock payments and SARs.

On February 28, 2018, the Company granted 1,610,599 stock options with a fair value of $10.01 per share and an exercise price of $35.09 per share; 2,391,933 shares of restricted stock and restricted stock units with a fair value of $35.09 per share; performance share awards to senior management employees with potential payouts varying from zero to 449,532 shares; and 14,228 SARs. The stock options vest over a three-year period from the grant date. The restricted stock and restricted stock units vest in three equal annual installments commencing on the first anniversary of the date of grant. The performance share awards can be earned based on performance against established goals over a three-year performance period. The performance share awards are based entirely on a TSR (total shareholder return) goal. Performance against the TSR goal is determined by comparing the performance of the Company’s TSR with the TSR performance of the members of the OSX index for the three-year performance period.

On May 11, 2018, the Company granted 35,432 restricted stock awards with a fair value of $40.65 per share. The awards were granted to non-employee members of the board of directors and vest on the first anniversary of the grant date.

Total stock-based compensation for all stock-based compensation arrangements under the Plan was $31 million and $58 million for the three and six months ended June 30, 2018, respectively, and $22 million and $52 million for the three and six months ended June 30, 2017, respectively. The total income tax benefit recognized in the Consolidated Statements of Income (Loss) for all stock-based compensation arrangements under the Plan was $4 million and $6 million for the three and six months ended June 30, 2018, respectively, and $5 million and $9 million for the three and six months ended June 30, 2017, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

10. Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is foreign currency exchange rate risk. Forward contracts against various foreign currencies are entered into to manage the foreign currency exchange rate risk on forecasted revenues and expenses denominated in currencies other than the functional currency of the operating unit (cash flow hedge). In addition, the Company will enter into non-designated forward contracts against various foreign currencies to manage the foreign currency exchange rate risk on non-functional-currency monetary accounts (non-designated hedge).

The Company records all derivative financial instruments at their fair value in its Consolidated Balance Sheet. Except for certain non-designated hedges discussed below, all derivative financial instruments that the Company holds are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Such arrangements typically have terms between 2 and 24 months, but may have longer terms depending on the underlying cash flows being hedged, typically related to the projects in our backlog. The Company may also use interest rate contracts to mitigate its exposure to changes in interest rates on anticipated long-term debt issuances.

At June 30, 2018, the Company has determined that the fair value of its derivative financial instruments representing assets of $21 million and liabilities of $15 million (primarily currency related derivatives) are determined using level 2 inputs (inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability) in the fair value hierarchy as the fair value is based on publicly available foreign exchange and interest rates at each financial reporting date. At June 30, 2018, the net fair value of the Company’s foreign currency forward contracts totaled a net asset of $6 million.

At June 30, 2018, the Company did not have any interest rate contracts and its financial instruments do not contain any credit-risk-related or other contingent features that could cause accelerated payments when the Company’s financial instruments are in net liability positions. We do not use derivative financial instruments for trading or speculative purposes.

Cash Flow Hedging Strategy

To protect against the volatility of forecasted foreign currency cash flows resulting from forecasted revenues and expenses, the Company has instituted a cash flow hedging program. The Company hedges portions of its forecasted revenues and expenses denominated in non-functional currencies with forward contracts. When the U.S. dollar strengthens or weakens against the foreign currencies, the change in present value of future foreign currency revenues and expenses is offset by changes in the fair value of the forward contracts designated as hedges.

For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is subject to a particular currency risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings (e.g., in “revenues” when the hedged transactions are cash flows associated with forecasted revenues). The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), or hedge components excluded from the assessment of effectiveness, is recognized in the Consolidated Statements of Loss during the current period.

For the six months ended June 30, 2018, the Company recognized a gain of $2 million as a result of the discontinuance of certain cash flow hedges when it became probable that the original forecasted transactions would not occur by the end of the originally specified time period. At June 30, 2018, there were $8 million in pre-tax losses recorded in accumulated other comprehensive income (loss). Significant changes in forecasted operating levels or delays in large capital construction projects, whereby certain hedged transactions associated with these projects are no longer probable of occurring by the end of the originally specified time period, could result in losses or gains due to the de-designation of existing hedge contracts.

The Company had the following outstanding foreign currency forward contracts that were entered into to hedge non-functional currency cash flows from forecasted revenues and expenses (in millions):

Non-designated Hedging Strategy

The Company enters into foreign currency forward contracts to hedge certain nonfunctional currency monetary accounts. The purpose of the Company’s foreign currency hedging activities is to protect the Company from risk that the eventual U.S. dollar equivalent cash flows from the non-functional currency monetary accounts will be adversely affected by changes in the exchange rates.

For derivative instruments that are non-designated, the gain or loss on the derivative instrument subject to the hedged risk (i.e., non-functional currency monetary accounts) is recognized in other income (expense), net in current earnings.

ASC Topic 260, “Earnings Per Share” requires companies with unvested participating securities to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method requires a portion of net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income (loss) attributable to Company allocated to these participating securities was immaterial for the three and six months ended June 30, 2018 and 2017 and therefore not excluded from net income attributable to Company per share calculation.

The Company had stock options outstanding that were anti-dilutive totaling 18 million for each of the three and six months ended June 30, 2018, and 18 million shares and 13 million shares for each of the three and six months ended June 30, 2017, respectively.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

13. Commitments and Contingencies

Our business is affected both directly and indirectly by governmental laws and regulations relating to the oilfield service industry in general, as well as by environmental and safety regulations that specifically apply to our business. Our business is also subject to trade regulations that may restrict or prohibit trade with certain countries, companies and/or individuals, such as trade sanctions applicable, for example, to Russia, Syria and Iran. Although we have not incurred material costs in connection with our compliance with such laws, there can be no assurance that other developments, such as new environmental laws, regulations and enforcement policies may not result in additional, presently unquantifiable, costs or liabilities to us. We are also subject to increasing local content and localization requirements in various jurisdictions, as well as increasing trade tariffs, retaliatory tariffs and other trade controversies, all of which could result in material negative impacts to our business.

The Company is involved in various claims, internal investigations, regulatory agency audits and pending or threatened legal actions, arbitration, litigation, and regulatory investigations, involving a variety of matters. In many instances, the Company maintains insurance that covers claims arising from risks associated with the business activities of the Company, including claims for injuries to third parties and third parties’ property, e.g., premises liability, product liability and other such claims. The Company carries substantial insurance to cover such risks above a self-insured retention. The Company believes and the Company’s experience has been that such insurance has been sufficient to cover such risks. See Item 1A. Risk Factors. If, however, such insurance were inapplicable or insufficient to cover such losses, there could be material negative impacts to our business.

The Company is also a party to claims, threatened and actual litigation, governmental regulatory proceedings and private arbitration arising from ordinary day to day business activities, in which parties assert claims against the Company for a broad spectrum of potential liabilities, including: individual employment law claims, collective actions under federal employment laws, intellectual property claims, e.g., alleged patent infringement, and/or misappropriation of trade secrets, premises liability claims, personal injuries arising from allegedly defective products, alleged improper payments under anti-corruption and anti-bribery laws and other commercial claims seeking recovery for alleged actual or exemplary damages. In currently pending litigation and arbitrations, adverse parties have asserted damages in material amounts for which they seek recovery from the Company. Due to the inherent risks and uncertainty of litigation, an unexpected adverse result may occur from time to time. For many such contingent claims, the Company’s insurance coverage is inapplicable or an exclusion to coverage may apply. In such instances, settlement or other resolution of such contingent claims could have a material financial or reputational impact on the Company.

As of June 30, 2018, the Company recorded reserves in an amount believed to be sufficient for contingent liabilities representing all contingencies believed to be probable to cover such liabilities. The Company has also assessed the potential for additional losses above the amounts accrued as well as potential losses for matters that are not probable but are reasonably possible. The total potential loss on these matters cannot be determined; however, in our opinion, any ultimate liability, to the extent not otherwise provided for and except for the specific cases referred to above, will not materially affect our financial position, cash flow or results of operations. These estimated liabilities are based on the Company’s assessment of the nature of these matters, their progress toward resolution, the advice of legal counsel and outside experts as well as management’s intention and experience.

Further, in some instances, direct or indirect consumers of our products and services, entities providing financing for purchases of our products and services or members of the supply chain for our products and services have become involved in governmental investigations, internal investigations, political or other enforcement matters. In such circumstances, such investigations may adversely impact the ability of consumers of our products, entities providing financial support to such consumers or entities in the supply chain to timely perform their business plans or to timely perform under agreements with us. We may also become involved in these investigations, at substantial cost to the Company.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

14. New Accounting Pronouncements

Recently Adopted Accounting Standards

In March 2017, the FASB issued Accounting Standard Update No. 2017-07 “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (ASU 2017-07). This update requires that an employer report the service cost component in the same line item as other compensation costs and separately from other components of net benefit cost. ASU 2017-07 is effective for fiscal periods beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

In August 2016, the FASB issued Accounting Standard Update No. 2016-15 “Classification of Certain Cash Receipts and Cash Payments” (ASU 2016-15). This update amends Accounting Standard Codification Topic No. 230 “Statement of Cash Flows” and provides guidance and clarification on presentation of certain cash flow issues. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. The Company adopted this update on January 1, 2018 with no material impact.

In May 2014, the FASB issued Accounting Standard Update No. 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU proscribes a five-step model for determining when and how revenue is recognized. Under the model, an entity will recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services.

ASU 2014-09 is effective for fiscal periods beginning after December 15, 2017. The Company adopted this update on January 1, 2018, using the modified retrospective approach, in which an immaterial cumulative effect adjustment was made to retained earnings. The adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the six months ended June 30, 2018. See Note 6 for additional details of the adoption of this standard.

Recently Issued Accounting Standards

In August 2017, the FASB issued Accounting Standard Update No. 2017-12 “Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities” (ASU 2017-12). This update improves the financial reporting of hedging relationships and simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective for fiscal periods beginning after December 15, 2018, and for interim periods within those fiscal years. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company is currently assessing the impact of the adoption of ASU No. 2017-12 on its consolidated financial position and results of operations.

In March 2016, the FASB issued ASC Topic 842, “Leases” (ASC Topic 842), which supersedes the lease requirements in ASC Topic No. 840 “Leases” and most industry-specific guidance. This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASC Topic 842 is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years.

In preparing for the adoption of this new standard, the Company has established an internal team to centralize the implementation process as well as engaged external resources to assist in our approach. We are currently utilizing a software program to consolidate and accumulate leases with documentation as required by the new standard. We have assessed the changes to the Company’s current accounting practices and are investigating the related tax impact and process changes. We are also in process of quantifying the impact of the new standard on our balance sheet.

Earnings Per Share [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase. See Note 7 for the fair value of long-term debt and Note 10 for the fair value of derivative financial instruments.

Net Loss Attributable to Company Per Share

ASC Topic 260, “Earnings Per Share” requires companies with unvested participating securities to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method requires a portion of net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income (loss) attributable to Company allocated to these participating securities was immaterial for the three and six months ended June 30, 2018 and 2017 and therefore not excluded from net income attributable to Company per share calculation.

Warranties

Warranties

The Company provides warranties on certain of its products and services. The Company accrues warranty liability based upon specific claims and a review of historical claim experience in accordance with Accounting Standards Codification (“ASC”) Topic 450 “Contingencies”. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered.
