NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    Basis of Presentation

The accompanying unaudited consolidated financial statements of Schlumberger Limited and its subsidiaries (Schlumberger) have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  In the opinion of Schlumberger management, all adjustments considered necessary for a fair statement have been included in the accompanying unaudited financial statements.  All intercompany transactions and balances have been eliminated in consolidation.  Operating results for the six-month period ended June 30, 2017 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2017.  The December 31, 2016 balance sheet information has been derived from the Schlumberger 2016 audited financial statements.  For further information, refer to the Consolidated Financial Statements and notes thereto included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2016, filed with the Securities and Exchange Commission on January 25, 2017.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers.  This ASU amends the existing accounting standards for revenue recognition and is based on the principlethat revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the considerationa company expects to receive in exchange for those goods or services.  Schlumberger will adopt this ASU on January 1,2018.  Schlumberger does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.  

In February 2016, the FASB issued ASU No. 2016-02, Leases.  This ASU requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases.  Schlumberger will adopt this ASU on January 1, 2019.  Based on its current lease portfolio, Schlumberger estimates that the adoption of this ASU will result in approximately $1.3 billion of additional assets and liabilities being reflected on its Consolidated Balance Sheet.

2.   Charges and Credits

Schlumberger recorded the following charges and credits during the first six months of 2017:

Second quarter 2017:

• During the second quarter of 2017, Schlumberger entered into a financing agreement with its primary customer in Venezuela.  This agreement resulted in the exchange of $700 million of outstanding accounts receivable for a promissory note with a three-year term that bears interest at the rate of 6.50% per annum.  Schlumberger recorded this note at its estimated fair value on the date of the exchange, which resulted in a pretax and after-tax charge of $460 million.  Schlumberger is accounting for the promissory note as an available-for-sale security reported at fair value in OtherAssets, with unrealized gains and losses included as a component of Accumulated other comprehensive loss.  The fair value of the promissory notes is based on management’s estimate of pricing assumptions that market participants would use.

During the second quarter of 2017, Schlumberger also entered into discussions with another customer relating to certain of its outstanding accounts receivable.  As a result of these ongoing discussions, Schlumberger recorded a pretax charge of $50 million ($38 million after taxes and noncontrolling interests) to adjust these receivables to their estimated net realizable value. 

These charges are classified in Impairments & other in the Consolidated Statement of Income (Loss).

• In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron), Schlumberger recorded $81 million of pretax charges ($64 million after-tax) consisting of employee benefits, facility consolidation and other merger and integration-related costs.  These charges are classified in Merger & integration in the Consolidated Statement of Income (Loss).

First quarter of 2017:

• In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron), Schlumberger recorded $82 million of pretax charges ($68 million after-tax) consisting of employee benefits, facility consolidation and other merger and integration-related costs.  These charges are classified in Merger & integration in the Consolidated Statement of Income (Loss).

The following is a summary of the charges and credits recorded during the first six months of 2017:

	(Stated in millions)

	Pretax		Tax		Interests		Net
Promissory note fair value adjustment and other	$	510	$	-	$	12	$	498
Merger & integration		164		31		-		133
	$	674	$	31	$	12	$	631

Schlumberger recorded the following charges and credits during the second quarter of 2016:

• As a result of the persistent unfavorable oil and gas industry market conditions that continued to deteriorate in the first half of 2016, and the related impact on first-half operating results and expected customer activity levels, Schlumberger determined that the carrying values of certain assets were no longer recoverable and took certain decisions that resulted in the following impairments and other charges:

- $646 million of severance costs associated with further headcount reductions.

- $209 million impairment of pressure pumping equipment in North America.

- $165 million impairment of facilities in North America.

- $684 million of other fixed asset impairments primarily relating to other underutilized equipment. 

- $616 million write-down of the carrying value of certain inventory to its net realizable value.

- $198 million impairment of certain multiclient seismic data, largely related to the US Gulf of Mexico.

- $55 million of other costs, primarily relating to facility closure costs.

The fair value of the impaired fixed assets and multiclient seismic data was estimated based on the projected present value of future cash flows that these assets are expected to generate.  Such estimates included unobservable inputs that required significant judgments.  Additional charges may be required in future periods should industry conditions worsen.  The above items are classified in Impairments & other in the Consolidated Statement of Income (Loss).

• In connection with Schlumberger’s acquisition of Cameron (see Note 4 – Acquisition of Cameron), Schlumberger recorded $185 million of charges, classified in Merger & integration in the Consolidated Statement of Income (Loss), consisting of the following: $47 million relating to employee benefits for change-in-control arrangements and retention bonuses;  $45 million of transaction costs, including advisory and legal fees;  $40 million of facility closure costs, and $53 million of other merger and integration-related costs.Additionally, Schlumberger recorded $150 million of charges related to the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value, which is classified in Cost of sales in the Consolidated Statement of Income (Loss),  This amortization was historically presented as a component of Merger & integration; however, Schlumberger reclassified this prior period amount to Cost of sales during the current quarter.

4.   Acquisition of Cameron

On April 1, 2016, Schlumberger acquired all of the outstanding shares of Cameron, a leading provider of flow equipment products, systems and services to the oil and gas industry worldwide. Schlumberger issued approximately 138 million shares of its common stock, which were valued at $9.9 billion at the time of closing, and paid cash of $2.8 billion.  Prior to being acquired by Schlumberger, Cameron reported revenue of approximately $1.6 billion during the first quarter of 2016.

Supplemental Pro Forma Financial Information

The following supplemental pro forma results of operations assume that Cameron had been acquired as of January 1, 2015.  The supplemental pro forma financial information was prepared based on the historical financial information of Schlumberger and Cameron and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable.  The pro forma amounts reflect certain adjustments to intangible asset amortization expense, interest and income taxes resulting from purchasing accounting.  The pro forma amounts also reflect adjustments to the 2016 results to exclude the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value and  other merger and integration costs of $254 million, net of taxes, for the three and six months ended June 30, 2016.

The supplemental pro forma financial information presented below does not include any anticipated cost savings or the expected realization of other synergies associated with this transaction.  Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisition occurred on January 1, 2015, nor is it indicative of future results of operations.

The estimated fair value of Schlumberger’s Long-term Debt, based on quoted market prices at June 30, 2017 and December 31, 2016, was $16.9 billion and $16.8 billion, respectively.

Borrowings under the commercial paper program at June 30, 2017 were $3.0 billion, of which $2.8 billion was classified within Long-term Debt and $0.2 billion was classified within Short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheet.  At December 31, 2016, borrowings under the commercial paper program were $2.6 billion, of which $2.4 billion was classified within Long-term debt and $0.2 billion was classified in Short-term borrowings and current portion of long-term debt in the Consolidated Balance Sheet.

10.   Derivative Instruments and Hedging Activities

Schlumberger is exposed to market risks related to fluctuations in foreign currency exchange rates and interest rates.  To mitigate these risks, Schlumberger utilizes derivative instruments.  Schlumberger does not enter into derivative transactions for speculative purposes.

Interest Rate Risk

Schlumberger is subject to interest rate risk on its debt and its investment portfolio.  Schlumberger maintains an interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its investment portfolio, and occasionally interest rate swaps, to mitigate the exposure to changes in interest rates.

During 2013, Schlumberger entered into a cross currency swap for a notional amount of €0.5 billion in order to hedge changes in the fair value of Schlumberger’s €0.5 billion 1.50% Guaranteed Notes due 2019.  Under the terms of this swap, Schlumberger will receive interest at a fixed rate of 1.50% on the euro notional amount and pay interest at a floating rate of three-month LIBOR plus approximately 64 basis points on the US dollar notional amount.

This cross currency swap is designated as a fair value hedge of the underlying debt.  This derivative instrument is marked to market with gains and losses recognized currently in income to largely offset the respective gains and losses recognized on changes in the fair value of the hedged debt.  

13

At June 30, 2017, Schlumberger had fixed rate debt of $13.9 billion and variable rate debt of $4.9 billion after taking into account the effect of the swap.

Short-term investments and Fixed income investments, held to maturity totaled $4.3 billion at June 30, 2017.  The carrying value of these investments approximated fair value, which was estimated using quoted market prices for those or similar investments.

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts its business in over 85 countries. Schlumberger’s functional currency is primarily the US dollar.  However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies.  Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar–reported expenses will increase (decrease).  

Schlumberger is exposed to risks on future cash flows to the extent that the local currency is not the functional currency and expenses denominated in local currency are not equal to revenues denominated in local currency.  Schlumberger is also exposed to risks on future cash flows relating to certain of its fixed rate debt that is denominated in currencies other than the functional currency.  Schlumberger uses foreign currency forward contracts to provide a hedge against a portion of these cash flow risks.  These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss.  Amounts recorded in Accumulated Other Comprehensive Loss are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings.  The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded directly to earnings.

At June 30, 2017, Schlumberger recognized a cumulative net loss of $0.1 million in Accumulated other comprehensive loss relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next 12 months.

Schlumberger is exposed to changes in the fair value of assets and liabilities that are denominated in currencies other than the functional currency.  While Schlumberger uses foreign currency forward contracts and foreign currency options to economically hedge this exposure as it relates to certain currencies, these contracts are not designated as hedges for accounting purposes.  Instead, the fair value of the contracts is recorded on the Consolidated Balance Sheet, and changes in the fair value are recognized in the Consolidated Statement of Income (Loss) as are changes in fair value of the hedged item.

At June 30, 2017, contracts were outstanding for the US dollar equivalent of $4.8 billion in various foreign currencies, of which $0.8 billion related to hedges of debt denominated in currencies other than the functional currency.

The fair values of outstanding derivative instruments were as follows:

			(Stated in millions)
	Fair Value of Derivatives				Consolidated Balance Sheet Classification

The fair value of all outstanding derivatives was determined using a model with inputs that are observable in the market or that can be derived from, or corroborated by, observable data.

The effect of derivative instruments designated as fair value hedges and those not designated as hedges on the Consolidated Statement of Income (Loss) was as follows:

						(Stated in millions)

Derivatives not designated as hedges:
Foreign exchange contracts	$	1	$	(57	)	$	7	$	(138	)	Cost of services/sales

11.   Contingencies

Schlumberger is party to various legal proceedings from time to time.  A liability is accrued when a loss is both probable and can be reasonably estimated.  Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote.  However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.

Reservoir Characterization Group

Reservoir Characterization Group revenue of $1.8 billion increased 9% sequentially primarily due to higher WesternGeco multiclient seismic license sales in the international markets.  Increased Testing & Process activity in the international markets and seasonal improvements in Wireline in Russia also contributed to the increase.

Pretax operating margin of 17% was essentially flat sequentially as the increased contribution from high-margin Wireline exploration activities was offset by reduced profitability in Testing & Process due to increased project costs.

Drilling Group

Drilling Group revenue of $2.1 billion increased 6% sequentially primarily due to the seasonal rebound in activity in the Russia & CIS and North Sea regions and strong directional drilling activity in US land.

Pretax operating margin of 14% increased 278 basis points (bps) sequentially due to increased volume and pricing improvements in US land.

Production Group

Production Group revenue of $2.5 billion was 14% higher sequentially as a result of strong hydraulic fracturing activity and a sustained pricing recovery in North America.  

Pretax operating margin of 9% increased 382 bps sequentially due to the increased activity and pricing recovery on land in North America.

19

Cameron Group

Cameron Group revenue of $1.3 billion increased 3% sequentially driven by higher Surface Systems and Valves & Measurement activity in US land.

Pretax operating margin of 14% improved 61 bps sequentially as increased project volumes and product sales in Surface Systems and Valves & Measurement and continued strong project execution in OneSubsea more than offset the impact of lower project activity in Drilling Systems.

Certain prior period items have been reclassified to conform to the current period presentation.

Second-quarter 2017 revenue of $7.5 billion increased 4% year-on-year. North America land rig count increased more than 150% versus the same period last year while the international land rig count was flat. The North America offshore rig count decreased by 26%, and the international offshore rig count was lower by 12%. Driven by the accelerated land activity growth in North America, Production Group revenue increased 18% year-on-year while Reservoir Characterization Group revenue was 11% higher driven by increases in WesternGeco and Testing & Process.  Drilling Group revenue increased by 4% while Cameron Group revenue declined 17%.

Second-quarter 2017 pretax operating margin increased 231 bps to 13%, as a result of improved profitability in North America due to accelerated land activity growth that benefited the Production and Drilling Groups.  As a result, Production Group pretax operating margin expanded 499 bps to 9% while Drilling Group increased 594 bps to 14%.  Reservoir Characterization Group pretax operating margin was essentially flat at 17% and the Cameron Group declined 260 bps to 14%.

Reservoir Characterization Group

Second-quarter 2017 revenue of $1.8 billion increased 11% year-on-year primarily due to higher WesternGeco and Testing & Process revenue on projects in the Middle East & Asia Area.  Strong WesternGeco multiclient seismic license sales in the international markets also contributed to the increase.

Year-on-year, pretax operating margin was essentially flat at 17% as increased revenue was offset by higher project costs in Testing & Process.

20

Drilling Group

Second-quarter 2017 revenue of $2.1 billion increased 4% year-on-year primarily due to higher demand for directional drilling technologies on land in North America.

Year-on-year, pretax operating margin increased 594 bps to 14% primarily due to improved profitability in North America due to accelerated land activity and improved pricing.

Production Group

Second-quarter 2017 revenue of $2.5 billion increased 18% year-on-year with most of the revenue increase attributable to the accelerated land activity growth in North America that benefited the pressure pumping business.

Year-on-year, pretax operating margin increased 499 bps to 9% as a result of improved profitability in North America due to accelerated land activity and improved pricing. 

Cameron Group

Second-quarter revenue of $1.3 billion declined 17% year-on-year, primarily due to a declining backlog for the long-cycle businesses of Drilling Systems and, to a lesser extent, OneSubsea.

Pretax operating margin of 14% declined 260 bps primarily due the decline in high-margin Drilling Systems project volumes.

Six-month revenue for the Drilling Group declined 10%, primarily driven by the 9% decline in the international rig count combined with Schlumberger's decision in April 2016 to reduce its activities in Venezuela in order to align operations with cash collections.  

21

These decreases were slightly mitigated by higher activity in US Land. Production Group revenue increased 4% as accelerated North America land  activity growth benefited the pressure pumping business. Reservoir Characterization Group revenue improved 2%.   

Six-month 2017 pretax operating margin increased 168 bps to 12%, as a result of improved profitability in North America due to accelerated land activity growth that benefited the Production and Drilling Groups.  As a result, Drilling Group pretax operating margin expanded 101 bps to 13% while the Production Group increased 66 bps to 7%.  Reservoir Characterization Group pretax operating margin declined 102 bps to 17% and the Cameron Group recorded a pretax operating margin of 13%.

Reservoir Characterization Group

Six-month 2017 revenue of $3.4 billion increased 2% year-on-year primarily due to higher WesternGeco and Testing & Process revenue on projects in the Middle East & Asia Area. 

Year-on-year, pretax operating margin decreased 102 bps to 17% due to reduced profitability in Testing & Process as project costs increased.

Drilling Group

Six-month 2017 revenue of $4.1 billion decreased 10% year-on-year primarily due to the drop in rig counts internationally and in offshore North America combined with pricing pressure.  Revenue also declined as a result of Schlumberger's decision in April 2016 to reduce its activities in Venezuela to align operations with cash collections.

Year-on-year, pretax operating margin increased 101 bps to 13% primarily due to improved profitability in North America land due to accelerated land activity and improved pricing; however this improvement in North America was partially offset by pricing pressure and activity declines internationally and the negative impact of reduced activity in Venezuela.

Production Group

Six-month 2017 revenue of $4.7 billion increased 4% year-on-year with most of the revenue increase attributable to the accelerated land activity growth in North America that benefited the pressure pumping product lines, which grew 15%.  Lower production levels in Ecuador negatively impacted Schlumberger Production Management projects, which partially offset the revenue increase.

Year-on-year, pretax operating margin increased 66 bps to 7% as a result of improved profitability in North America due to accelerated land activity and improved pricing.  This was offset by lower profitability in Schlumberger Production Management projects due to lower production in Ecuador.

Cameron Group

Cameron Group contributed six-month 2017 revenue of $2.5 billion.  Cameron Group revenue for the six months of 2016 only reflected only one quarter of revenue following the acquisition closing in April 2016.  Revenue in 2017 was impacted by a declining project backlog particularly for the long-cycle businesses of Drilling Systems and OneSubsea .

Year-on-year pretax operating margin of 13% was 260 bps lower as a result of lower Drilling Systems project volumes.

Interest and Other Income

Interest & other income consisted of the following:

Other

Research & engineering and General & administrative expenses, as a percentage of Revenue, for the second quarter and six months ended June 30, 2017 and 2016 were as follows:

	Second Quarter						Six Months
	2017			2016			2017			2016
Research & engineering		2.6	%		3.6	%		2.8	%		3.6	%
General & administrative		1.5	%		1.4	%		1.4	%		1.6	%

Research & engineering costs for the second quarter of 2017 and the six months ended June 30, 2017 have decreased as compared to the same periods in 2016 by $61 million and $91 million, respectively, as a result of cost control measures, offset in part by the impact of the Cameron acquisition.

The effective tax rate for the second quarter of 2017 was 590% as compared to 14.6% for the same period of 2016. The charges described in Note 2 to the Consolidated Financial Statements increased the effective tax rate for the second quarter of 2017 by 571 percentage points, as the majority of these charges were not tax-effective. Excluding the impact of these charges, the effective tax rate increased primarily as a result of the change in the geographic mix of earnings as Schlumberger generated a greater portion of its pretax earnings in North America during the second quarter of 2017 as compared to the same period last year.

The effective tax rate for the six months ended June 30, 2017 was 42.1% as compared to 14.2% for the same period of 2016. The charges described in Note 2 to the Consolidated Financial Statements increased the effective tax rate for the six months ended June 30, 2017 by 24.7 percentage points, as the majority of these charges were not tax-effective. Excluding the impact of these charges, the effective tax rate increased primarily as a result of the change in the geographic mix of earnings as Schlumberger generated a greater portion of its pretax earnings in North America during the first six months of 2017 as compared to the same period last year.

^{(1)  “}Net debt” represents gross debt less cash, short-term investments and fixed income investments, held to maturity.  Management believes that Net debt provides useful information regarding the level of Schlumberger’s indebtedness by reflecting cash and investments that could be used to repay debt.  Net debt is a non-GAAP financial measure that should be considered in addition to, not as a substitute for or superior to, total debt.

⁽²⁾ Includes depreciation of property, plant and equipment and amortization of intangible assets, multiclient seismic data costs and SPM investments.

⁽³⁾ Includes severance payments of approximately $230 million and $545 million during the six months ended June 30, 2017 and 2016, respectively.

⁽⁴⁾ “Free cash flow” represents cash flow from operations less capital expenditures, SPM investments and multiclient seismic data costs capitalized. Management believes that free cash flow is an important liquidity measure for the company and that it is useful to investors and management as a measure of our ability to generate cash.  Once business needs and obligations are met, this cash can be used to reinvest in the company for future growth or to return to shareholders through dividend payments or share repurchases.  Free cash flow does not represent the residual cash flow available for discretionary expenditures.  Free cash flow is a non-GAAP financial measure that should be considered in addition to, not as substitute for or superior to, cash flow from operations.

 Key liquidity events during the first six months of 2017 and 2016 included:

• On July 18, 2013, the Schlumberger Board of Directors (the “Board”) approved a $10 billion share repurchase program to be completed at the latest by June 30, 2018.  This program was completed during May 2017.  On January 21, 2016, the Board approved a new $10 billion share repurchase program for Schlumberger common stock.  Schlumberger had repurchased $1.8 million of shares under the new program as of June 30, 2017.

The following table summarizes the activity under these share repurchase programs:

(Stated in millions, except per share amounts)
	Total cost		Total number		Average price
	of shares		of shares		paid per
	purchased		purchased		share
Six months ended June 30, 2017	$	770		10.2	$	75.40
Six months ended June 30, 2016	$	506		7.5	$	67.65

25

• Capital expenditures were $0.9 billion during the first six months of 2017 compared to $1.0 billion during the first six months of 2016.  Capital expenditures for full-year 2017 are expected to be approximately $2.2 billion as compared to expenditures of $2.1 billion in 2016.

Schlumberger maintains an allowance for doubtful accounts in order to record accounts receivable at their net realizable value.  Judgment is involved in recording and making adjustments to this reserve.  Allowances have been recorded for receivables believed to be uncollectible, including amounts for the resolution of potential credit and other collection issues such as disputed invoices.  Schlumberger does not believe that these estimates are reasonably likely to materially change in the foreseeable future, however, adjustments to the allowance may be required in future periods depending on how such potential issues are resolved, or if the financial condition of Schlumberger’s customers were to deteriorate resulting in an impairment of their ability to make payments.

In April 2016, Schlumberger announced that it would reduce its activity in Venezuela to align operations with cash collections as a result of insufficient payments received in recent quarters.  As of June 30, 2017 Schlumberger’s net accounts receivable balance in Venezuela was approximately $0.5 billion, which excludes the $0.2 billion carrying value of the promissory notes described in Note 2 to the Consolidated Financial Statements.

Schlumberger continues to experience payment delays from certain other customers as well, primarily a result of the impact of lower oil prices in the oil and gas industry.  In this regard, included in Receivables less allowance for doubtful accounts in the Consolidated Balance Sheet as of June 30, 2017 is approximately $1.1 billion of receivables relating to Ecuador.

Schlumberger’s receivables from its primary customers in Venezuela and Ecuador are not in dispute and Schlumberger has not historically had any material write-offs due to uncollectible accounts receivable relating to these customers.

During weak economic environments or when there is an extended period of weakness in oil and gas prices, Schlumberger typically experiences delays in the payment of its receivables.  However, Schlumberger has not had material write-offs due to uncollectible accounts receivable over the recent industry downturn.  Schlumberger operates in more than 85 countries.  As a large multinational company with a long history of operating in a cyclical industry, Schlumberger has extensive experience in working with its customers during difficult times to manage its accounts receivable.  At June 30, 2017, only five of those countries individually accounted for greater than 5% of Schlumberger’s net receivable balance, of which only two (the United States and Ecuador) accounted for greater than 10% of such receivables.

On March 24, 2017, Schlumberger and Weatherford announced an agreement to create OneStim^SM, a joint venture to deliver completions products and services for the development of unconventional resource plays in the United States and Canada land markets.  The joint venture will offer one of the broadest multistage completions portfolios in the market combined with one of the largest hydraulic fracturing fleets in the industry.  Schlumberger and Weatherford will have a 70%/30% ownership of the joint venture, respectively.  The transaction is expected to close in the second half of 2017 and is subject to regulatory approvals and other customary closing conditions.  Under the terms of the formation agreement, Schlumberger and Weatherford will contribute all their respective North America land hydraulic fracturing pressure pumping assets, multistage completions, and pump-down perforating businesses.  Schlumberger will also make a $535 million cash payment to Weatherford.  Schlumberger will manage the joint venture and consolidate it for financial reporting purposes.

Cash flow from operations for the six months ended June 30, 2017 decreased by approximately $1.3 billion.  This decrease was primarily driven by the delays in collecting certain receivables combined with the effects of the impact of the activity growth experienced during the second quarter of 2017, as well as expected future growth.

As of June 30, 2017, Schlumberger had $6.2 billion of cash and short-term investments on hand.  Schlumberger had separate committed debt facility agreements aggregating $6.6 billion with commercial banks, of which $3.5 billion was available and unused as of June 30, 2017.  The $6.6 billion of committed debt facility agreements included $6.3 billion of committed facilities that support commercial paper programs.  Schlumberger believes these amounts are sufficient to meet future business requirements for at least the next 12 months.

Borrowings under the commercial paper programs at June 30, 2017 were $3.0 billion.

ventures and alliances; future global economic conditions; and future results of operations. These statements are subject to risks and uncertainties, including, but not limited to, global economic conditions; changes in exploration and production spending by Schlumberger’s customers and changes in the level of oil and natural gas exploration and development; general economic, political and business conditions in key regions of the world; foreign currency risk; pricing pressure; weather and seasonal factors; operational modifications, delays or cancellations; production declines; changes in government regulations and regulatory requirements, including those related to offshore oil and gas exploration, radioactive sources, explosives, chemicals, hydraulic fracturing services and climate-related initiatives; the inability of technology to meet new challenges in exploration; the inability to integrate the Cameron business and to realize expected synergies; the inability to retain key employees; and other risks and uncertainties detailed in this second-quarter 2017 Form10-Q and our most recent Form 10-K, and Forms 8-K filed with or furnished to the Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of any such development changes), or should our underlying assumptions prove incorrect, actual outcomes may vary materially from those reflected in our forward-looking statements. Schlumberger disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

For quantitative and qualitative disclosures about market risk affecting Schlumberger, see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” of the Schlumberger Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Schlumberger’s exposure to market risk has not changed materially since December 31, 2016.

Item 4. Controls and Procedures.

Schlumberger has carried out an evaluation under the supervision and with the participation of Schlumberger’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of Schlumberger’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this report, Schlumberger’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports that Schlumberger files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Schlumberger’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to its management, including the CEO and the CFO, as appropriate, to allow timely decisions regarding required disclosure. There was no change in Schlumberger’s internal control over financial reporting during the quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, Schlumberger’s internal control over financial reporting.

Issuer Repurchases of Equity Securities

On July 18, 2013, the Board approved a $10 billion share repurchase program for shares of Schlumberger common stock, to be completed at the latest by June 30, 2018.  This program was completed during May 2017.  On January 21, 2016, the Board approved a new $10 billion share repurchase program for Schlumberger common stock.  This new program took effect once the July 18, 2013 program was exhausted.  

Schlumberger’s common stock repurchase activity for the three months ended June 30, 2017 was as follows:

	(Stated in thousands, except per share amounts)
	Total number of shares purchased		Average price paid per share		Total number of shares purchased as part of publicly announced programs		Maximum value of shares that may yet be purchased under the programs
April 2017		1,542.0	$	76.83		1,542.0	$	10,154,265
May 2017		2,519.2	$	71.85		2,519.2	$	9,973,264
June 2017		1,435.5	$	68.36		1,435.5	$	9,875,124
		5,496.7	$	72.34		5,496.7

In connection with the exercise of stock options under Schlumberger’s incentive compensation plans, Schlumberger routinely receives shares of its common stock from optionholders in consideration of the exercise price of the stock options. Schlumberger does not view these transactions as requiring disclosure under this Item as the number of shares of Schlumberger common stock received from optionholders is not material.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Our mining operations are subject to regulation by the federal Mine Safety and Health Administration under the Federal Mine Safety and Health Act of 1977. Information concerning mine safety violations or other regulatory matters required by section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this report.

Item 5. Other Information.

Schlumberger completed the wind down of its service operations in Iran during 2013. Prior to this, certain non-US subsidiaries of Schlumberger provided oilfield services to the National Iranian Oil Company and certain of its affiliates (“NIOC”).

28

Schlumberger’s residual transactions or dealings with the government of Iran in the second quarter of 2017 consisted of payments of taxes and other typical governmental charges. Certain non-US subsidiaries of Schlumberger maintain depository accounts at the Dubai branch of Bank Saderat Iran (“Saderat”), and at Bank Tejarat (“Tejarat”) in Tehran and in Kish for the deposit by NIOC of amounts owed to non-US subsidiaries of Schlumberger for prior services rendered in Iran and for the maintenance of such amounts previously received. One non-US subsidiary also maintains an account at Tejarat for payment of local expenses such as taxes. Schlumberger anticipates that it will discontinue dealings with Saderat and Tejarat following the receipt of all amounts owed to Schlumberger for prior services rendered in Iran.

During the fourth quarter of 2016, a non-US subsidiary entered into a memorandum of understanding (“MOU”) with NIOC relating to the non-disclosure of data required for the technical evaluation of an oilfield project.  In the first quarter of 2017, the Schlumberger subsidiary provided NIOC with written notice that it was terminating the MOU, effective March 11, 2017. The MOU did not involve the provision of services.  During the second quarter of 2017, and in furtherance of the termination of the MOU, the Schlumberger subsidiary had residual dealings with the NIOC consisting solely of the return of client data.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

1.    Basis of Presentation

The accompanying unaudited consolidated financial statements of Schlumberger Limited and its subsidiaries (Schlumberger) have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  In the opinion of Schlumberger management, all adjustments considered necessary for a fair statement have been included in the accompanying unaudited financial statements.  All intercompany transactions and balances have been eliminated in consolidation.  Operating results for the six-month period ended June 30, 2017 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2017.  The December 31, 2016 balance sheet information has been derived from the Schlumberger 2016 audited financial statements.  For further information, refer to the Consolidated Financial Statements and notes thereto included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2016, filed with the Securities and Exchange Commission on January 25, 2017.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers.  This ASU amends the existing accounting standards for revenue recognition and is based on the principlethat revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the considerationa company expects to receive in exchange for those goods or services.  Schlumberger will adopt this ASU on January 1,2018.  Schlumberger does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.  

In February 2016, the FASB issued ASU No. 2016-02, Leases.  This ASU requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases.  Schlumberger will adopt this ASU on January 1, 2019.  Based on its current lease portfolio, Schlumberger estimates that the adoption of this ASU will result in approximately $1.3 billion of additional assets and liabilities being reflected on its Consolidated Balance Sheet.

Restructuring And Related Activities [Abstract]

Charges and Credits

2.   Charges and Credits

Schlumberger recorded the following charges and credits during the first six months of 2017:

Second quarter 2017:

• During the second quarter of 2017, Schlumberger entered into a financing agreement with its primary customer in Venezuela.  This agreement resulted in the exchange of $700 million of outstanding accounts receivable for a promissory note with a three-year term that bears interest at the rate of 6.50% per annum.  Schlumberger recorded this note at its estimated fair value on the date of the exchange, which resulted in a pretax and after-tax charge of $460 million.  Schlumberger is accounting for the promissory note as an available-for-sale security reported at fair value in Other Assets, with unrealized gains and losses included as a component of Accumulated other comprehensive loss.  The fair value of the promissory notes is based on management’s estimate of pricing assumptions that market participants would use.

During the second quarter of 2017, Schlumberger also entered into discussions with another customer relating to certain of its outstanding accounts receivable.  As a result of these ongoing discussions, Schlumberger recorded a pretax charge of $50 million ($38 million after taxes and noncontrolling interests) to adjust these receivables to their estimated net realizable value. 

These charges are classified in Impairments & other in the Consolidated Statement of Income (Loss).

• In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron), Schlumberger recorded $81 million of pretax charges ($64 million after-tax) consisting of employee benefits, facility consolidation and other merger and integration-related costs.  These charges are classified in Merger & integration in the Consolidated Statement of Income (Loss).

First quarter of 2017:

• In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron), Schlumberger recorded $82 million of pretax charges ($68 million after-tax) consisting of employee benefits, facility consolidation and other merger and integration-related costs.  These charges are classified in Merger & integration in the Consolidated Statement of Income (Loss).

The following is a summary of the charges and credits recorded during the first six months of 2017:

	(Stated in millions)

Merger & integration		164		31		-		133
	$	674	$	31	$	12	$	631

Schlumberger recorded the following charges and credits during the second quarter of 2016:

• As a result of the persistent unfavorable oil and gas industry market conditions that continued to deteriorate in the first half of 2016, and the related impact on first-half operating results and expected customer activity levels, Schlumberger determined that the carrying values of certain assets were no longer recoverable and took certain decisions that resulted in the following impairments and other charges:

- $646 million of severance costs associated with further headcount reductions.

- $209 million impairment of pressure pumping equipment in North America.

- $165 million impairment of facilities in North America.

- $684 million of other fixed asset impairments primarily relating to other underutilized equipment. 

- $616 million write-down of the carrying value of certain inventory to its net realizable value.

- $198 million impairment of certain multiclient seismic data, largely related to the US Gulf of Mexico.

- $55 million of other costs, primarily relating to facility closure costs.

The fair value of the impaired fixed assets and multiclient seismic data was estimated based on the projected present value of future cash flows that these assets are expected to generate.  Such estimates included unobservable inputs that required significant judgments.  Additional charges may be required in future periods should industry conditions worsen.  The above items are classified in Impairments & other in the Consolidated Statement of Income (Loss).

• In connection with Schlumberger’s acquisition of Cameron (see Note 4 – Acquisition of Cameron), Schlumberger recorded $185 million of charges, classified in Merger & integration in the Consolidated Statement of Income (Loss), consisting of the following: $47 million relating to employee benefits for change-in-control arrangements and retention bonuses;  $45 million of transaction costs, including advisory and legal fees;  $40 million of facility closure costs, and $53 million of other merger and integration-related costs.Additionally, Schlumberger recorded $150 million of charges related to the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value, which is classified in Cost of sales in the Consolidated Statement of Income (Loss),  This amortization was historically presented as a component of Merger & integration; however, Schlumberger reclassified this prior period amount to Cost of sales during the current quarter.

Acquisition of Cameron

4.   Acquisition of Cameron

On April 1, 2016, Schlumberger acquired all of the outstanding shares of Cameron, a leading provider of flow equipment products, systems and services to the oil and gas industry worldwide. Schlumberger issued approximately 138 million shares of its common stock, which were valued at $9.9 billion at the time of closing, and paid cash of $2.8 billion.  Prior to being acquired by Schlumberger, Cameron reported revenue of approximately $1.6 billion during the first quarter of 2016.

Supplemental Pro Forma Financial Information

The following supplemental pro forma results of operations assume that Cameron had been acquired as of January 1, 2015.  The supplemental pro forma financial information was prepared based on the historical financial information of Schlumberger and Cameron and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable.  The pro forma amounts reflect certain adjustments to intangible asset amortization expense, interest and income taxes resulting from purchasing accounting.  The pro forma amounts also reflect adjustments to the 2016 results to exclude the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value and  other merger and integration costs of $254 million, net of taxes, for the three and six months ended June 30, 2016.

The supplemental pro forma financial information presented below does not include any anticipated cost savings or the expected realization of other synergies associated with this transaction.  Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisition occurred on January 1, 2015, nor is it indicative of future results of operations.

Derivative Instruments and Hedging Activities

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

10.   Derivative Instruments and Hedging Activities

Schlumberger is exposed to market risks related to fluctuations in foreign currency exchange rates and interest rates.  To mitigate these risks, Schlumberger utilizes derivative instruments.  Schlumberger does not enter into derivative transactions for speculative purposes.

Interest Rate Risk

Schlumberger is subject to interest rate risk on its debt and its investment portfolio.  Schlumberger maintains an interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its investment portfolio, and occasionally interest rate swaps, to mitigate the exposure to changes in interest rates.

During 2013, Schlumberger entered into a cross currency swap for a notional amount of €0.5 billion in order to hedge changes in the fair value of Schlumberger’s €0.5 billion 1.50% Guaranteed Notes due 2019.  Under the terms of this swap, Schlumberger will receive interest at a fixed rate of 1.50% on the euro notional amount and pay interest at a floating rate of three-month LIBOR plus approximately 64 basis points on the US dollar notional amount.

This cross currency swap is designated as a fair value hedge of the underlying debt.  This derivative instrument is marked to market with gains and losses recognized currently in income to largely offset the respective gains and losses recognized on changes in the fair value of the hedged debt.  

At June 30, 2017, Schlumberger had fixed rate debt of $13.9 billion and variable rate debt of $4.9 billion after taking into account the effect of the swap.

Short-term investments and Fixed income investments, held to maturity totaled $4.3 billion at June 30, 2017.  The carrying value of these investments approximated fair value, which was estimated using quoted market prices for those or similar investments.

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts its business in over 85 countries. Schlumberger’s functional currency is primarily the US dollar.  However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies.  Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar–reported expenses will increase (decrease).  

Schlumberger is exposed to risks on future cash flows to the extent that the local currency is not the functional currency and expenses denominated in local currency are not equal to revenues denominated in local currency.  Schlumberger is also exposed to risks on future cash flows relating to certain of its fixed rate debt that is denominated in currencies other than the functional currency.  Schlumberger uses foreign currency forward contracts to provide a hedge against a portion of these cash flow risks.  These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss.  Amounts recorded in Accumulated Other Comprehensive Loss are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings.  The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded directly to earnings.

At June 30, 2017, Schlumberger recognized a cumulative net loss of $0.1 million in Accumulated other comprehensive loss relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next 12 months.

Schlumberger is exposed to changes in the fair value of assets and liabilities that are denominated in currencies other than the functional currency.  While Schlumberger uses foreign currency forward contracts and foreign currency options to economically hedge this exposure as it relates to certain currencies, these contracts are not designated as hedges for accounting purposes.  Instead, the fair value of the contracts is recorded on the Consolidated Balance Sheet, and changes in the fair value are recognized in the Consolidated Statement of Income (Loss) as are changes in fair value of the hedged item.

At June 30, 2017, contracts were outstanding for the US dollar equivalent of $4.8 billion in various foreign currencies, of which $0.8 billion related to hedges of debt denominated in currencies other than the functional currency.

The fair values of outstanding derivative instruments were as follows:

			(Stated in millions)
	Fair Value of Derivatives				Consolidated Balance Sheet Classification

	2017		2016

The fair value of all outstanding derivatives was determined using a model with inputs that are observable in the market or that can be derived from, or corroborated by, observable data.

The effect of derivative instruments designated as fair value hedges and those not designated as hedges on the Consolidated Statement of Income (Loss) was as follows:

11.   Contingencies

Schlumberger is party to various legal proceedings from time to time.  A liability is accrued when a loss is both probable and can be reasonably estimated.  Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote.  However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers.  This ASU amends the existing accounting standards for revenue recognition and is based on the principlethat revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the considerationa company expects to receive in exchange for those goods or services.  Schlumberger will adopt this ASU on January 1,2018.  Schlumberger does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.  

In February 2016, the FASB issued ASU No. 2016-02, Leases.  This ASU requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases.  Schlumberger will adopt this ASU on January 1, 2019.  Based on its current lease portfolio, Schlumberger estimates that the adoption of this ASU will result in approximately $1.3 billion of additional assets and liabilities being reflected on its Consolidated Balance Sheet.
