## Letter to Shareholders

On April 1, 2016, Schlumberger completed its acquisition of Cameron International, combining our complementary portfolios into a pore to pipeline products and services offering for the oil and gas industry. The transaction enables the creation of technology-driven growth by integrating Schlumberger reservoir and well technology with Cameron wellhead and surface equipment, flow control, and processing technology.



Schlumberger revenue of $27.8 billion in 2016 represented a decrease of 22% from 2015, despite three quarters of activity from the acquired Cameron Group, which contributed $4.2 billion in revenue. Excluding the Cameron Group, revenue

Chairman and Chief Executive Officer

declined 34%. This revenue drop was due to continued weakness in exploration and production spending as a result of the deepest and longest industry crisis in more than 30 years.

The year began with Brent crude prices experiencing the sharpest fall in 30 years to $26 per barrel in January 2016, thus continuing the downturn that the oil and gas industry endured during the previous year.

Given two successive years of investment cuts, oil supply growth slowed significantly despite record OPEC production. Non-OPEC production fell sharply, largely due to a significant drop in US light tight oil production. However, robust global demand enabled the oil market to tighten and draw down on the vast accumulation of crude and product stocks by midyear.

The year’s end was marked by OPEC and certain non-OPEC countries, including Russia, agreeing to cut production by a combined 1.7 million barrels per day. These agreements are expected to accelerate the drawdown of stocks in 2017 and have subsequently spurred a recovery in oil prices, which reached $55 per barrel at the end of 2016.

In the natural gas markets, US production declined during 2016 as a result of the drop in gas drilling activity, while demand growth was robust throughout the year. Low gas prices during most of 2016 encouraged the power sector to continue to favor gas over coal. The year was also marked by the start-up of the Sabine Pass liquefied natural gas (LNG) plant in Texas, which exported its first shipment in early 2016, thus starting a trend that should make the US the third largest exporter of LNG by the end of 2020.

Europe continued to see modest demand growth, due in part to coal plant retirements. Gas prices, however, fell to a seven-year low as supplies from Russia, Norway, and North Africa reached record highs. The Asian markets continued to be in slow growth mode, albeit with slight improvements in China. Nonetheless, oversupply persisted as Australian LNG exports ramped up, driving LNG prices down even further from the already low levels of 2015. The global outlook for LNG is largely unchanged, with continued oversupply and low prices.



Our financial performance in 2016 was severely impacted by the significant decrease in activity, particularly in North America, where the average land rig count dropped 46% as compared with the previous year. Supply overcapacity in the land market remained high for most of 2016, resulting in pricing pressure across a broad range of oilfield services. As a result, North America revenue, excluding the impact of Cameron, decreased 48% due to a decrease in US land revenue of 52%. Including the Cameron Group, North America revenue decreased 32%. Internationally, revenue declined 28%, excluding the impact of Cameron (17% including the Cameron Group) due to customer budget cuts, activity disruptions, and a shift in revenue mix that impacted our results in most basins and market segments around the world. Revenue in the Europe, CIS & Africa Area decreased due to lower demand for exploration and development-related products and services as E&P budgets were reduced, particularly in Sub-Saharan Africa. In Latin America, revenue declined due to customer budget constraints across the area and, more specifically, in Venezuela, where operations were scaled back to align with collections. Middle East & Asia revenue decreased primarily due to reduced activity in Asia-Pacific countries, while robust activity in the Middle East was more than offset by pricing concessions.

Since the start of this downturn, and as it deepened during 2016, Schlumberger has navigated the commercial landscape by balancing pricing concessions and market share and also by proactively removing significant costs through workforce reductions, internal efficiency improvements, and strong supply chain management. As a result, Schlumberger has delivered superior financial results by maintaining pretax operating margins above 10% and delivering sufficient free cash flow to cover a range of strategic capital investments, as well as our ongoing dividend commitments.

After nine quarters of unprecedented activity decline, the business environment stabilized in the third quarter of 2016 and revenue increased slightly in the fourth quarter, suggesting that the bottom of this cycle had been reached.

In spite of the activity decline, new technology sales across all Groups were sustained at 20% of total sales, which is above the levels seen in the previous downturn. The company's commitment to technology innovation was reinforced with key commercializations, including the AxeBlade \( ^{*} \)  ridged diamond element bit, which improves drilling rate of penetration in a wide range of formations; Maze \( ^{*} \)  microfluidic SARA analysis for reservoir fluids characterization, which is the first commercial application of microfluidic analysis technology in the oil and gas industry; and OpenPath Sequence \( ^{*} \)  diversion stimulation service, which sequentially diverts acid into additional clusters or zones to maximize wellbore coverage, resulting in more precise treatment placement and greater production in comparison with conventional methods.








Our health and safety performance, including the Cameron Group since the second quarter of 2016, has shown steady progress. First, the total recordable injury frequency decreased 13% to the lowest rate since we started keeping records in 2000. Our automotive accident rate for the combined company showed a slight deterioration compared with 2015, which reinforces our commitment to improve driving and implement journey management across the entire company.

In terms of environmental performance, our technologies enabled our customers to lower their environmental impact while optimizing the recovery of nonrenewable resources. By combining our advanced technology with increased engagement in the communities where we work, we are achieving lower emissions, decreased water usage, and reduced unplanned releases to the environment. This is documented in our Global Stewardship Reports.
“By combining our advanced technology with increased engagement in the communities where we work, we are achieving lower emissions, decreased water usage, and reduced unplanned releases to the environment.”

When we aligned our resource structure with current activity levels, everyone at Schlumberger was affected by this difficult process because there is no easy way to let go of employees who are friends and colleagues. Despite these changes, we remain confident in our ability to serve our customers now and when market conditions improve.

We accelerated the pace of our transformation program as the year progressed. For example, we created the Field Deployment Lead organization and piloted our new IT platform in Ecuador. In addition, we trained more than 13,000 of our employees on the Schlumberger transformation and the methodology that will change the way we work, leading to improved performance for Schlumberger and our customers.

In our constructive view of the oil markets, the tightening of the supply and demand balance continued in the fourth quarter as seen by a steady draw in OECD stocks. Therefore, in the later parts of 2017 and leading into 2018 we expect to see accelerating growth in E&P investment in the main producing regions around the world driven by growth in demand, decreasing supply, and the challenge of replacing production lost to decline.

On behalf of the Schlumberger people located in more than 85 countries around the globe, I would like to thank our shareholders and customers for their confidence in us. I would also like to express my thanks to our employees, the best and most professional women and men in the oil and gas services industry, for their commitment and focus.



Paal Kibsgaard

Chairman and Chief Executive Officer




## Performed by Schlumberger

Schlumberger people are driven by excellence and the never-ending quest to exceed expectations. Their unwavering commitment to customers, innovative technology, safety, and quality is the foundation for the company’s leading position in the oilfield services industry.

The Performed by Schlumberger program, started in 2001, recognizes projects and their team members throughout the company who have demonstrated excellence in teamwork, innovation, and business impact for Schlumberger.

In 2016, 740 projects from approximately 50 countries representing 55 distinct customers competed for the highest tribute, the Chairman’s Award. The award recognizes one project as an outstanding example of the company’s core values: our people, our commitment to technology, and our determination to produce superior profits.

The Integrated Services Management (ISM) team won this year’s Chairman’s Award for its contribution to the planning and services execution for Shell and its affiliates (Shell) on the Sail & Drill project—a dedicated mobile rig moving from country to country, covering Europe and Africa, drilling deepwater exploration and appraisal wells.

The ISM model collocated, integrated, and aligned the objectives of the Shell and Schlumberger teams. Schlumberger The Sail & Drill team received the Performed by Schlumberger Award from Chairman and CEO Paal Kigsgaard (far left) and President Europe and Africa Bill Coates (far right).

achieved HSE “Goal Zero” on this flagship project, which concluded in February 2016 after drilling five wells in three countries—Benin, Turkey, and Gabon. The project drilled a total of 52,887 ft while successfully managing complicated logistics.

The Shell Sail & Drill project leveraged key aspects of the Schlumberger transformation program. Using an integrated services model increased rigor in planning and execution and boosted overall service efficiency. In addition, product and process reliability contributed to strong operations integrity.

Shell acknowledged the key role ISM played in the project, in particular with its support during unplanned events. The Sail & Drill project is also a good example of a new business model to deliver a series of single-string venture wells.



## Pore to Pipeline

In its 2016 World Energy Outlook, the International Energy Agency determined that demand for oil and gas would require more than $17 trillion in upstream investment from now until 2040. Despite record investment between 2010 and 2014, conventional oil discoveries fell to a 70-year low in 2015 and the number of conventional oil projects approved for development in 2016 dropped to the lowest level since the 1950s. How then can the oil and gas industry maintain supply to meet demand in the longer term with commodity prices likely remaining in a medium-for-longer environment?










## Meeting the Challenge

The last two years have been a part of the deepest industry downturn in more than 30 years. Competition between sources of supply from conventional and unconventional oil reservoirs has forced commodity prices lower as production exceeded demand. Yet, even before such competition began, the upstream industry was already technically and financially challenged when oil was trading at more than $100 a barrel.

For Schlumberger, the way to ensure that future investment can meet increased demand for oil and gas is by providing our customers technology and business models that improve efficiency and enable unprecedented levels of collaboration and integration across the full spectrum of E&P technology—from pore to pipeline. Our extensive history of building market-leading technologies is a solid foundation for providing the sustainable solutions the E&P industry needs to meet future demand.

Combining technology with new business models and advanced integrated systems connects our customers to the full potential of the domain expertise and data we can provide at every stage of the pore to pipeline process. We have the industry’s strongest platforms of individual and integrated oilfield technologies that—coupled with our data, software, and domain expertise to exploit the value of information and knowledge—puts us in the ideal position to leverage the market recovery that has now begun to emerge.

In entering what we believe to be a medium-for-longer oil price environment, it has become clear that the oil and gas industry needs to change. Schlumberger is well ahead of this trend: for the last eight years, we have been implementing a transformation program that focuses on changing the way we work. These changes are already positively affecting our long-term performance as well as that of our customers.

“Providing our customers technology and business models that improve efficiency and enable unprecedented levels of collaboration and integration across the full spectrum of E&P technology—from pore to pipeline.”

## Building Technology Leadership

Before 1930, petroleum engineers and geologists determined the nature of subsurface rocks based on the core samples or cuttings they extracted from boreholes. These methods, however, were neither a practical nor consistently reliable means to identify oil-bearing formations. The future of oil exploration changed significantly in 1927 when Conrad and Marcel Schlumberger conducted the first wireline log by creating a way to measure the electrical resistivity of rock formations in boreholes to provide insight into hydrocarbon-bearing formations and open a new era in reservoir characterization.

The subsequent evolution of the Schlumberger family business into the company it is today built on this foundation of reservoir expertise and paved the way for significant future growth. Now, 90 years since the company was founded, our Reservoir Characterization Group continues to be a driving force behind the development of new technology. Combining our domain expertise and software applications with the ability to take measurements at a scale that ranges from the microns of a reservoir’s pores to the miles of an entire basin enables our customers to develop geological models and simulations that can improve hydrocarbon production and recovery.

Following a number of moves into drilling-related activities that began in the 1950s, the acquisition of Smith International and Geoservices in 2010 led to the creation of the Schlumberger Drilling Group, offering a complete range of drill bits, drilling tools, measurement- and logging-while-drilling services, drilling fluids, and mud logging capabilities. The Group brings together all of the bottomhole assembly components into integrated downhole systems that leverage our knowledge of instrumentation, software, drilling optimization, and automation.

While we have actively built on the scientific platform of the Production Group portfolio, mergers and acquisitions have also added to our offering, beginning with the purchase of Johnston Testers in 1956. The creation of Dowell Schlumberger in 1960 brought experience in pressure pumping and well testing and the acquisition of Camco International in 1998 added completion hardware that, combined with our reservoir expertise, enabled us to create an intelligent completion system capable of monitoring and controlling the reservoir in situ. In addition, by applying the latest advances in fluid chemistry with our subsurface knowledge to hydraulic fracturing, we have developed

technology that has improved well production and overall recovery while decreasing the wellsite footprint and reducing water and proppant consumption.

Historically, the focus of Schlumberger has been on the subsurface, in particular, on formation evaluation and the characterization of the reservoir. As we develop new ways of improving total system performance in drilling and production, we see considerable untapped potential that can be harnessed through the integration of surface and subsurface technologies for more effective oil and gas exploration and production. Therein lies the rationale behind our merger with Cameron International in 2016, which has now created the industry’s first pore to pipeline portfolio of technology products and services.

The ongoing integration of Schlumberger reservoir and well technology with Cameron wellhead, flow control, and surface equipment into total drilling and production systems is set to provide a step change in performance that addresses the long-term production challenges the oil and gas industry faces.
Our pore to pipeline journey starts with the technology used to fully characterize and understand the subsurface environment in which the well is to be drilled.

## Characterizing the Reservoir

During its life cycle, every reservoir passes through the same stages, but some of the most critical decisions are made early on, from discovery to appraisal. Reservoir discovery initiates an intensive data acquisition phase that collects geological information from seismic surveys and cores, logs, and productivity tests.

The Reservoir Characterization Group brings together domain experts from multiple petrotechnical disciplines. Enabled by Schlumberger technology and reservoir workflows, these experts help determine and model reservoir properties for our customers. Seismic surveys are essential for this work because they provide the only measurement made at the reservoir scale for both the creation and refinement of reservoir models that decrease risk throughout the development planning and production management phases of the reservoir.




Two geoscientists review well trajectories for an onshore unconventional play in the Schlumberger Digital Technology Theater in Houston, Texas. The integration of petrophysical measurements and three-dimensional seismic data in the Petrel platform helps engineers develop predictive maps of sweet spots.

To significantly advance the quality of marine seismic data, Schlumberger developed the Q-Marine \( ^{*} \)  point-receiver marine seismic system and the Q-Seabed \( ^{*} \)  multicomponent seabed seismic system. We have evolved offshore seismic surveys even further with IsoMetrix \( ^{*} \)  marine seismic technology, which provides the most detailed imaging of the subsurface, from seabed to reservoir in every direction. These detailed images help to reduce risk and uncertainty during field development planning.

Yet before the field development plan can unfold, the large-scale view of the field must transition to a finer view, at the wellbore scale. To achieve this, our advanced wireline logging portfolio provides customers with a more complete understanding of complex reservoirs. For more than a decade, formation properties have been measured by the Scanner \( ^{*} \)  rock and fluid characterization services family, which delivers a broad array of measurements and analysis—from water volume, salinity, and rock texture to fluid saturation, typing, and producibility. Given its measurement reliability, wireline technology even has applications beyond the Earth’s subsurface. For example, NASA evaluated the performance of Litho Scanner \( ^{*} \)  high-definition spectroscopy service as highly effective in accurately measuring the bulk elemental composition of rocks toward support of a future Venus lander mission proposal.

Well logging is still one of our greatest strengths. It has evolved into a series of more than 100 different services. One of the most recent is Quanta Geo \( ^{*} \)  photorealistic reservoir geology service, which extends the generation of wellbore images that accurately represent formation geology to wells drilled with oil-base mud, where conventional imaging tools cannot fully function. Quanta Geo service provides information about structural and sedimentological features, helping to reveal the best methods to release hydrocarbons from the rock pores and how we can make them flow into the well.

By integrating geological and geophysical models with dynamic well test data, GeoTesting \( ^{*} \)  geology-based well test design and interpretation services maximize the value of well tests. A plug-in for the Petrel \( ^{*} \)  E&P software platform, GeoTesting services can improve characterization



accuracy for the geologically complex reservoirs that make up a greater proportion of today's oil and gas production.

It is also important to rapidly simulate flow performance to generate a variety of production scenarios. CoreFlow \( ^{*} \)  digital rock and fluid analytics services create 3D rock and fluid models that enable operators to make informed decisions in the span of a few days rather than months or years. By combining digital and physical rock and fluid analyses, CoreFlow services deliver more comprehensive reservoir answers faster than compared with conventional methods to enhance understanding of the dynamic processes in the reservoir pore.

Supporting this enhanced understanding is our global network of rock and fluid analysis laboratories that provide industry-leading technologies and workflows for core processing and analysis, including advanced fluid inclusion technology. The recently inaugurated Schlumberger Reservoir Laboratory in Abu Dhabi, UAE, is our latest state-of-the-art rock analysis laboratory, expanding our network for customers in the Middle East and Asia.

Reservoir characterization must thoroughly evaluate downhole risks. This evaluation begins at the individual wellbore environment as customers bring together all available data into the Techlog \( ^{*} \)  wellbore software platform for analysis and validation. The answer products can then be seamlessly imported into a shared earth environment using the Petrel software platform, enabling petrotechnical experts to understand and characterize the geology surrounding the wellbore, thus improving hydrocarbon recovery.

These software platforms are complemented by powerful physics engines, such as the INTERSECT \( ^{*} \)  high-resolution reservoir simulator for quick and accurate simulation of reservoir behavior over time and OLGA \( ^{*} \)  dynamic multiphase flow simulator for modeling multiphase transient flow within the production system. The engines are used to optimize field development plans and facilities design as well as enable superior asset life cycle management. Schlumberger software builds on more than 30 years of research and engineering (R&E) investment. This investment incorporates deep domain knowledge, supported by the industry’s largest team of petrotechnical experts, and the latest software development practices and digital technology applications. More than 3,500 companies around the globe use our software to achieve their reservoir simulation goals.

# “NASA evaluated the performance of Litho Scanner service as highly effective in accurately measuring the bulk elemental composition of rocks toward support of a future Venus lander mission proposal.”

Our investment in science and knowledge together with our expertise in information systems is fueling the digital enablement of reservoir characterization to create a digital representation of the subsurface that leverages all available information in the planning, execution, and optimization of E&P operations. We are committed to continuing the technology leadership that this demands by increasing collaboration and integration via cloud-native solutions based on both public and private cloud infrastructures. With the support of our Software Technology Innovation Center in Silicon Valley, we are able to partner with technology industry leaders and quickly appraise emerging digital technology, validate its value for our industry, and adopt it for our technology development and offerings.

Following the development of understanding through reservoir characterization, the next step in the pore to pipeline journey is well construction, from bottomhole drilling assemblies incorporating bits and drilling tools to fluid systems and cementing.

## Constructing the Well

The wellbore environment is harsh, requiring technological sophistication and efficient operational execution to deliver success. Every well and reservoir comprises a unique set of conditions, which is one of the reasons the industry has created separate drilling components with optimal performance that can be combined to address the specific needs of each well.

To improve drilling performance, we have integrated the entire drilling system—the bottomhole assembly, drilling fluid, drillstring, and surface equipment—with a drilling workflow that uses data from all drilling system technologies. The acquisitions of Smith International



## Integrated Drilling System

For years, the industry has been applying discrete drilling technologies and depending on enhancements of these to improve performance. While this has produced notable technical advancements, the logical next step is to fully integrate the well construction process by adopting a holistic, consistent, and collaborative approach to managing the entire drilling system.

Our platform of drilling technologies is the industry’s largest and broadest—the ideal starting position for our vision to revolutionize the well construction cycle by comprehensively integrating business and technical systems with domain-driven, best-in-class technology. The centerpiece is our land drilling system of the future, which represents the ultimate integrated drilling system.

The land drilling system of the future brings together our leading surface and downhole hardware with comprehensive optimization software and our established ability to leverage the value of the data to create a step change in operational efficiency. This development knits together years of research from our drilling center in Cambridge, England, with the extensive expertise and downhole technology of our Drilling Group product lines. From the drilling equipment portfolio of Cameron, we are integrating top drive, pipe handling, and blowout preventer technologies. The result is not the usual incremental change from individual products and services but a game-changing synergistic performance improvement.



Aided by a central Drilling Technology Integration Center, the Schlumberger integrated drilling system redefines traditional workflows and crew member roles to reduce the total work hours and the resources required to drill a well. This highly collaborative environment increases well construction efficiency, minimizes risks, and ultimately reduces cost per barrel.

and Geoservices in 2010 were instrumental in enabling Schlumberger to achieve this level of integration.

There are three key objectives of the drilling performance workflow. The first is increasing overall drilling efficiency, which is a function of the rate of penetration and the overall time actually spent drilling. Drilling efficiency—spanning improved rock cuttings extraction, lower cost, and a smaller environmental footprint—is critical for the economic recovery of hydrocarbons. To meet this challenge, our PowerDrive \( ^{*} \)  rotary steerable systems family helps steer wells in a wide variety of environments, from ultrahigh temperatures of 392 degF to wells with highly abrasive rocks. During the last decade, PowerDrive rotary steerable systems have drilled more than 200 million ft in wells from vertical to horizontal.

Drilling performance, including improvements in the rate of penetration, has been further enhanced by new developments in drillbit cutters that operate in three dimensions. For example, AxeBlade \( ^{*} \)  ridged diamond element bit technology employs a ridge-shaped geometry that cuts rock in a new way by combining the shearing action of a conventional polycrystalline diamond compact (PDC) cutter with the crushing action of a tungsten carbide insert.

Another important aspect for drilling efficiency is the fluid, or mud, used to lubricate the bit, transport cuttings from the bottom of the wellbore to the surface, control pressure to prevent unwanted fluids from entering the well, and maintain wellbore stability. Drilling mud effectively reduces the torque, drag, and dispersion that can slow the drill bit's rate of penetration by using oil, water, or a synthetic fluid as a base. However, in general, using an oil-base mud for higher performance adds additional costs for the required transport and disposal of the resulting waste. The cost-effective solution is our new HydraGlyde \( ^{*} \)  high-performance water-base drilling system, which completely eliminates the waste and disposal costs while delivering a rate of penetration comparable to that of oil-base mud.

The second objective of the drilling performance workflow is precise well placement and formation evaluation to maximize production and provide quantitative reservoir



characterization. This requires the acquisition and interpretation of a combination of surface and downhole measurements that are used to guide, or “geosteer,” the drill bit and enhance reservoir characterization. Accurate geosteering depends on real-time data from logging- and measurements-while-drilling technologies. GeoSphere \( ^{*} \)  reservoir mapping-while-drilling service uses deep, directional electromagnetic measurements to reveal subsurface bedding and fluid contact details more than 100 ft from the wellbore. These measurements also help to refine the reservoir’s boundaries for maximizing reservoir exposure.

The third drilling performance workflow objective is wellbore evaluation and assurance, defined as protecting the integrity of the well throughout its productive life. Our leadership positions in petrotechnical skills, workflow processes, and subsurface engineering help our customers

efficiently evaluate the cement placement to determine wellbore assurance.

There is, however, another aspect of drilling integration that is vital across the entire well construction process: the combination of technology with domain experts and field-proven operational processes. Located around the world, Schlumberger Drilling Technology Integration Centers provide 24/7 performance assurance for drilling operations on land and offshore. Remote support from the multidisciplinary technical specialists staffing the centers produces sustained reductions in nonproductive drilling time.

Now that Cameron has joined Schlumberger, our well construction portfolio has expanded to include pressure control and topside drilling equipment and support services to shipyards, drilling contractors, E&P operators, and rental tool companies. This expanded set of products and services, which offers a new market for Schlumberger, features Cameron blowout preventers (BOPs), BOP control systems, and marine drilling riser systems. Cameron brought the first BOP to market in 1922 and remains one of the industry's leading manufacturers and technology providers.

The drilling process yields considerable volumes of data about the efficiency of the process itself and the subsurface environment. Digital technology that can accelerate the learning curve, improve efficiency, and ensure that the relevant information is seamlessly delivered to the right people at the right time is now beginning to change the drilling process.

Once the well has been drilled, the next step in the pore to pipeline journey is completing the well, from setting the casing, liner, and production tubing to perforating and installing monitoring and control systems as well as constructing the wellhead.

## Completing the Well

Completion technologies unlock hydrocarbons from rock pores and facilitate their flow to the wellbore. Completing a well usually involves installing seamless steel pipe to form a casing string with cement pumped into the annulus between the casing and the wellbore to zonally isolate the well. A stable path must then be created for the oil or gas to reach the surface.

Perforations are made in the casing to open the well-bore to flow before stimulation technologies are used to maximize both flow rate and recovery. One technique in particular, hydraulic fracturing, is commonly performed

The combination of an automated stimulation delivery platform with fluid delivery and flowback services delivers hydraulic fracturing fluid to the wellbore, including fluid flowback and any subsequent well testing operations.

on oil and gas wells in low-permeability reservoirs. This technique pumps engineered fluids at high rates and high pressures into the section to be produced, which creates fractures in the rock. The proppant mixed with the fluids, usually sand or ceramic spheres, keeps the fractures open so the oil and gas can flow to the wellbore. With the move to more oil and gas development in unconventional reservoirs in North America, a number of new technologies have been introduced to improve this process.

Since its deployment in 2010, the HiWAY \( ^{*} \)  flow-channel fracturing technique has increased average well production in unconventional reservoirs by 20% while also reducing proppant use by 40% and water use by 25%. Other advanced Schlumberger technologies, such as BroadBand \( ^{*} \)  unconventional reservoir completion services, further improve economics by ensuring that every fracture system is kept open from tip to wellbore. For example, one application of BroadBand Sequence \( ^{*} \)  fracturing service in a horizontal well in the Wolfcamp Shale in the Midland basin in Texas increased production by 42%.
Unconventional reservoir operations also require efficiency to decrease total well costs. By integrating the CAMShale \( ^{*} \)  fracturing fluid delivery and flowback service with Schlumberger downhole technologies, more streamlined operations can be achieved. In addition, by engaging a multi-skilled workforce using Cameron surface equipment, more stages can be completed per day to lower total well costs.

Once a well has been stimulated, artificial lift pumps must be installed because only about 5% of oil and gas wells have enough pressure to flow naturally. Since our 1998 acquisition of Camco International, Schlumberger has established a leadership position in electric submersible pumps (ESP) through continuous development of REDA \( ^{*} \)  ESP systems, the history of which goes back to 1926. Schlumberger ESP systems now have integrated sensors that not only take the measurements necessary to optimize performance but also measure well pressure and temperature. These measurements can signal when pump performance is starting to decline or if the well needs work-over operations to maintain production levels.



## Integrated Completions System

The rapid development of unconventional resources in North America has led to innovative new technologies that have improved the efficiency and effectiveness of completion and production services. With activity set to grow in unconventional resource production both in North America and internationally, Schlumberger is focusing on the development of an integrated completion technology system.

A primary component of the integrated completion system is the hydraulic fracturing system of the future, which combines Production Group technologies with significant process reengineering and universal operating and optimization software. This new system interfaces our automated stimulation delivery platform with a range of Cameron pressure control and wellhead systems and the Schlumberger portfolio of comprehensive perforating, fracturing cleanup, and flowback services; the latest downhole completion technologies; and advanced fracturing fluids.



The automated stimulation delivery platform is a complete redesign of bulk handling, mixing, and pumping surface equipment to improve reliability through automation, real-time data capture, advanced analytics, and predictive equipment health models. Improved equipment reliability leads to increased operational efficiency, including reduced nonproductive time and higher asset utilization.

The integration of fracturing fluid delivery and flowback services seamlessly delivers hydraulic fracturing fluid to the wellbore, including fluid flowback and any subsequent well testing operations, while new operating software provides process-control monitoring
of inventory and equipment performance. Execution via standardized work processes for operations and equipment maintenance and the deployment of multiskilled crews significantly enhance wellsite efficiency and safety.



With this combination of industry-leading technologies, software, and geoengineering workflows, the Schlumberger integrated completions system of the future is expected to deliver highly consistent operational performance—reducing the cost per barrel and lowering the capital intensity of hydraulic fracturing operations.
The automated stimulation delivery platform shown above incorporates a self-contained proppant delivery and storage system that streamlines materials management; improves health, safety, and environmental performance; and increases operational efficiency. The image at the upper left shows frac trees and frac manifolds connected by Monoline \( ^{*} \)  flanged-connection fracturing fluid delivery technology, which enable faster mobilization and increase fracturing uptime while requiring fewer technicians on location. Monoline technology simplifies the rig-up procedure by arriving on location preassembled, thereby reducing installation time by more than 60%.



The most common artificial lift method used, which is also the most economical in low flow conditions, is a rod lift system with progressing cavity pumps (PCPs). Beginning in May 2013, Schlumberger acquired 12 rod lift companies throughout North America as well as a leading market player in PCP systems. Currently, Schlumberger is the only provider of lift services throughout the full production life cycle that complement our highly collaborative and technology-based business models for pore to pipeline solutions.

During its lifetime, a producing well usually requires workover operations to maintain, improve, or restore production through mechanical repair or fluid-based treatment. Workover operations often use coiled tubing systems to save operating costs and reduce health, safety, and environmental risks by avoiding the need to install a rig. ACTive \( ^{*} \)  real-time downhole coiled tubing services offer an advantage by using fiber optics to accurately measure key well parameters, such as real-time pressure and temperature. The data can then be swiftly interpreted to optimize production flow while reservoir treatments are still in progress for completing the workover with only one trip in the wellbore.

Ultimately, the most effective way to avoid workover operations is to install an intelligent completion that incorporates permanent downhole sensors and surface-controlled downhole flow control valves. These sensors and valves enable operators to monitor, evaluate, and manage production or injection in real time without the need for well interventions. The evolving challenges of large-scale developments on land and offshore, as well as the need to maximize reservoir contact, ensure well integrity, and manage uncertainty, were the impetus behind the development of the Manara \( ^{*} \)  production and reservoir management system.

The Manara system is the result of an eight-year collaboration between Saudi Aramco and Schlumberger to develop an intelligent completion system for multi-zone, multilateral, extended-reach, and extreme reservoir contact wells. Integrating 30 patented technologies, the Manara system realizes permanent, real-time monitoring of downhole pressure, temperature, water cut, and flow rate as well as provides in-lateral flow control of zones. This high-level monitoring enables engineers to make production decisions in hours rather than the typical days or weeks when using conventional completion systems.



This multidisciplinary team is using the Avocet* production operations software platform to analyze production data. By combining data and measurements acquired from production operations with simulation models, the Avocet platform provides technical insights into the reasons for production interruptions and shortfalls.

With artificial lift systems operating in nearly every well, and the number of intelligent completion systems increasing every year, well and reservoir data are more readily available. Advanced software solutions to manage these intelligent completion systems provide a management tool to increase operational efficiency based on data intelligence that tracks performance, alerts operators about events, and pinpoints problems. At the same time, this management tool cuts through the sheer volume of big data, which can obscure understanding for taking the right action at the right time.

It takes the Avocet \( ^{*} \)  production operations software platform to efficiently and cost-effectively manage production by coupling modeling software and engineering

workflows. Designed to handle the complexities of production operations, the Avocet software platform conditions, validates, and stores high-frequency, real-time data for creating a complete picture of field production over time. When operational conditions change, users have the tools to identify the reasons behind production discrepancies and use operational decision making and planning workflows that take into account the economic impact throughout the life of the field.

With the reservoir producing to the surface, the next stage of the pore to pipeline journey concerns the production systems that collect, separate, and treat the production fluids before delivery to the pipeline.

## Producing the Field

With our acquisition of Cameron, Schlumberger now provides technology from the wellhead to the pipeline that recovers and stores hydrocarbons, manages water quality, controls and enhances asset performance, maintains well equipment, and monitors produced streams both on land and offshore. These technologies include surface and platform systems, such as wellhead and production trees, chokes, safety, dry access production, artificial lift, separation and processing, valves and valve automation, and measurement.

The separation and processing systems that make up the production facilities for a given onshore field are typically designed to not only treat the initial production, which includes varying amounts of gas, oil, and water, but also to accommodate the expected changes in production over time.

The removal and treatment of produced water, for example, requires safe and reliable handling that adheres to international environmental standards and regulations. MYCELX \( ^{®} \)  RE-GEN advanced water treatment media is used as a primary or secondary treatment method for removing oil and suspended solids without the use of chemicals. Optimizing water treatment is also possible with a 50% smaller footprint using the EPCON Dual \( ^{®} \)  compact flotation unit that simultaneously improves the efficiency with which oil and gas are removed from water. These technologies are only two of our many solutions to help increase operational efficiency while reducing operational cost.



## Integrated Production System

Today’s production systems can take several years to design and build, thus delaying the time to first oil. But reservoir production is not consistent—it changes over time. Therefore, facilities must be designed to handle the most challenging processing conditions that could occur over the field’s productive life. These considerations often result in overdesign, further delays, and additional capital outlay.

The Schlumberger production system of the future, however, will provide a fully integrated facility connecting the subsurface and surface. The process will begin with downhole real-time measurements and controls to manage and match production to optimally designed surface processing facilities.

The reservoir and surface data will be used in the design of standard and custom-engineered process, separation, and treatment technologies for oil, gas, water, and solids. By integrating our broad portfolio of processing capabilities and industry-leading subsurface modeling, the system will accommodate a wide range of production operating environments and accelerate the time to first oil.

Schlumberger integrated production and process facilities will be assembled in the field via modular, interchangeable units that readily allow easy modification and inclusion of necessary separation and treatment technologies from first oil to mature production. With the wealth of field knowledge available through extensive monitoring capabilities, our customers will benefit from data analytics and automation to efficiently manage the production facility’s level of autonomy.

Aligned to create value at every stage in the production life of a field—from fast-tracking first oil to peak and mature production rates—the modularity and flexibility of the Schlumberger integrated production system will enable optimization at any targeted production rate, effluent condition, or export oil quality requirement. The result is fine-tuned production performance and improved field economics.



Engineers review a computer-aided-design image of the Scurry Area Canyon Reef Operators Committee (SACROC) gas processing facility for  \( CO_{2} \)  reinjection and hydrocarbon recovery at the Digital Technology Theatre in Houston, Texas. This method of enhanced oil recovery frees the oil molecules from the reservoir’s pores so they can flow into the production wells, where they are then separated in facilities such as the one shown here.



Once crude oil is gathered in tanks, it must be processed to obtain the correct quality level, which can be a time-consuming process with a number of sensitive variables. The NATCO DUAL FREQUENCY \( ^{*} \)  electrostatic treater can be employed to meet crude export regulations by dehydrating and desalting crude oil with better efficiency than any other solution available. This technology reduces operating costs and provides customers with a faster return on investment.

Before crude oil is delivered to a refinery, it is blended to create crude with specific physical properties. Heavy and extraheavy crudes, for example, are blended with lighter crude oils to reduce viscosity, which makes them easier to transport. Crude oil blending systems, part of the Cameron Group, achieve target quality by instantly responding to changes while keeping production costs to a minimum. In

one operation, crude oil blending systems were installed in two separate terminals feeding four refineries. The systems were designed to blend a domestic high-wax crude into a flowing pipeline containing imported crude oil without causing wax deposition in the main pipeline. In more than four years of operation, these systems enabled the blending of significantly more waxy crude without deposition, thereby increasing customer revenue by millions of dollars per year.

Pipeline transmission of hydrocarbons depends heavily on the valves used and measurements made along the way. Schlumberger now has the industry’s most complete range of valves and measurement systems for midstream and downstream markets through the acquisition of Cameron, which has more than 60 years of experience in the provision of valves for every environment found around the globe. This expertise also includes the fiscal and custody transfer measurement of large volumes of oil and gas as well as the fully integrated measurement and control systems that enable customers to enhance products and processes in real time.

Offshore, and particularly in deepwater fields, operations are more complex. For three years prior to the 2016 acquisition of Cameron by Schlumberger, the companies worked together in the OneSubsea joint venture, which was created to extract value from the integration of Schlumberger reservoir and well technology with Cameron wellhead and surface equipment, flow control, and processing technology.

OneSubsea combines technology and innovation to develop the integrated solutions, processing systems, and control systems that increase production and recovery in subsea developments. These integrated solutions enable optimization of the entire system, from the reservoir to the surface, and include well completions and subsea production systems. Offshore Australia, OneSubsea has developed the world’s first unified control system that spans the boosting system and the subsea architecture, the well completion, and the landing string. This new integrated technology controls all seafloor operations at a lower capital cost per barrel. Furthermore, by accounting for changing conditions during the life of the field, our integrated solution can help our customers reach first oil faster, accelerate production, and increase recovery.

Prior to the creation of OneSubsea, Schlumberger had already established leadership in a few of the distinct parts of complete subsea systems, such as subsea landing string services that reduce risk by overcoming the complexity that deep waters, high pressures, and extreme temperatures



## Integrated Subsea Production System

To optimize production and recovery from the increasingly challenging reservoirs in subsea projects, the industry is developing more sophisticated subsea processing equipment and control systems with a focus on flow assurance and monitoring asset integrity. But it takes more than individual technological improvements to achieve a step change in subsea operations.

The Schlumberger integrated subsea production system, born from the OneSubsea joint venture established in 2013, employs a pore to pipeline approach to meet these challenges. By combining reservoir analysis and production assurance with advanced subsea hardware engineering, OneSubsea is successfully delivering technology solutions that are substantially improving production performance and recovery.

This robust capability comes from the joined knowledge and experience of Schlumberger and Cameron implemented through early engagement with customers during field development. Our deep understanding of reservoir dynamics, asset modeling, production assurance, and subsea production and processing technologies informs a unique, innovative perspective that translates into effective performance throughout the field’s life to increase return on investment.

Complementing the integrated system framework, OneSubsea is setting new technology benchmarks, such as the development of 20,000-psi subsea systems to meet the demands of high-pressure, high-temperature (HPHT) reservoirs. These systems complement current HPHT offerings and leverage the Cameron Group’s substantial experience with production trees and high-pressure, large-bore blowout preventers.

In the future, one way to improve the return and cash flow of offshore developments will be to take a more phased, modular approach, as opposed to deploying monolithic full-scale developments. Another option is the development of subsea fields by using existing surface processing and production facilities, thereby reducing the time and expense required to build new infrastructure. Through OneSubsea, Schlumberger is helping customers transform their subsea developments by integrating production operations, well performance, and reservoir management around a shared dynamic asset model.

place on subsea operations. We also lead the market in subsea multiphase boosting and metering as well as wet gas compression through the 2011 acquisition of Framo Engineering AS, a company that specialized in the business of developing and manufacturing multiphase and subsea pumps and multiphase metering systems. The acquisition followed on the heels of a 14-year collaboration between Framo Engineering and Schlumberger for the development of multiphase metering.

Subsea oil and gas reservoirs present significant challenges owing to their high development cost and the need for complex well designs and advanced subsea architecture requirements. In addition, the technical and commercial limitations of subsea production typically result in recovery rates that are often less than half of those for traditional topside development. Although deepwater reserves account for approximately 10% of global oil reserves, the ability to maximize recovery from every subsea project expands the industry’s options for meeting the world’s increasing demand for energy.

## Integrating Business Models

Integrating technology with business models along the pore to pipeline journey is enabling the introduction of better-aligned business models in which risk and reward are shared between operators and service companies throughout the life of the field. This approach leverages the complementary capabilities of our customers with our own.

Although as much as 80% of our work is still performed under a standard single-product-line contract in which we price our differentiated technologies separately, we can also provide technical support during the operational phases of a customer's project. At the simplest level, this begins with our Integrated Services Management (ISM) for which specially trained project managers provide scheduling, planning, and activity coordination for the various Schlumberger product lines involved in any given project.

At a more complex level, our Integrated Drilling Services (IDS) and Integrated Production Services (IPS) offerings provide project management, engineering design, and technical optimization capabilities on contracts where commercial terms provide performance-based compensation to Schlumberger IPS. For IDS contracts, this is typically focused on how fast we can drill each well or how optimally we place it in the reservoir, whereas for IPS the contracts focus on turnkey intervention work or extracting incremental production for individual wells.

The highest level of integration we provide is through our Schlumberger Production Management (SPM) model, in which we take full-field management responsibility using the complete range of Schlumberger products, services, and technical expertise. The general scope of SPM agreements covers developing a subsurface model; creating a field development plan; designing, drilling, and tying a large number of wells into production; and managing the production and associated facilities. The development may require flowlines, gas gathering stations, a central processing plant, and the management of third parties.

In addition, SPM brings the integration of Schlumberger oilfield technologies along with access to world-class technical know-how and emerging technologies and workflows that use the latest reservoir and simulation software. The benefits associated with SPM include rapid and cost-effective field acreage derisking, reduction of drilling and completion learning curves and costs, production optimization, and improved recovery factors. These benefits result in improved cash flow, reduced operating costs, and decreased capital expenditure.

The SPM model fills a growing market need between the traditional service company and E&P company business models and generally involves the management of mature asset field redevelopment, greenfield development, or the development of unconventional resources. The longer-term nature of these contracts enables Schlumberger R&E to develop fit-for-purpose technologies and methodologies to maximize operating efficiency, increase productivity, and reduce the environmental footprint.

In terms of risk management, SPM has developed rigorous methodologies and standards to evaluate and manage each opportunity. SPM contracts, where we risk the value of our products and services and, in certain cases, additional cash investments, can reach up to 20 years in duration. With these contracts we are compensated for our work through the value of the production we generate from the field.

The origins of SPM stem from Schlumberger Integrated Project Management (IPM), which since 1995 has provided project management services to customers around the world, including production management services. Worldwide, more than 10,000 wells have been drilled and successfully brought to production—a performance backed by several thousand dedicated oilfield specialists, including engineers and geoscientists specialized in world-class field development technologies. In 2016, we acquired Asset Development and Improvement Limited (ADIL), which complements the asset development capability of SPM, and created a Center of Excellence for asset development for Schlumberger and its customers.

During the past 20 years, we have expanded the size, complexity, and number of SPM projects we undertake to the point that today we manage approximately 230,000 barrels per day of oil equivalent production.

Production management commercial models are flexible and performance based. Projects are executed under a long-term service contract, and SPM’s compensation is linked to incremental production. The commercial models include production incentives for services, technical alliances with production gain share, comanaged assets remunerated on a tariff per barrel produced, and net profit incentive-based compensation.

One such model involves the rapid development of low-cost gas reserves to LNG. The combination of Schlumberger reservoir knowledge, wellbore technologies, and production management capabilities with Golar LNG Limited’s low-cost

As a result of this secure, cloud-based application, onsite and remote viewers gain valuable insight into fluid injection profiles and diversion stage success during the BroadBand Sequence fracturing service. This ability to make real-time adjustments to the pumping schedule leads to more effective stimulation and ensures every cluster delivers its full potential, which ultimately reduces the cost per barrel.

## Digitally Connecting Pore to Pipeline

Schlumberger is the world’s leading oilfield services company. For more than 90 years we have steadily grown, adding new products and services to our technology portfolio while building a series of market-leading product lines. The major acquisitions of Camco International in 1998, Smith International in 2010, and Cameron International in 2016 have enabled us to develop a unique pore to pipeline offering that now covers the full range of E&P services.

The E&P industry has yet to realize the full potential that data can offer. Putting the right information in the right hands at the right time is critical, and only possible if backed by deep domain expertise. At the operational level, this also requires that the individual technologies deployed in the field attain the highest possible productivity levels. This is enabled by integrated systems based on a digital infrastructure that permits the validation, application, and sharing of critical information. In turn, understanding operational workflows and building greater connections between technical domains can increase efficiency and minimize risk while seeking to overcome the complex challenges of the future.

As the industry begins to recover from the deepest downturn it has seen in more than 30 years, the breadth of the Schlumberger portfolio positions us well in any market. Combining technology with new business models and digital enablement connects our customers to the full potential of the domain expertise and data we can provide at every stage of the pore to pipeline process. With activities in more than 85 countries and employees who represent over 140 nationalities, we offer a truly global approach.

## PART I

## Item 1. Business.

All references in this report to “Registrant,” “Company,” “Schlumberger,” “we” or “our” are to Schlumberger Limited (Schlumberger N.V., incorporated in Curaçao) and its consolidated subsidiaries.

Founded in 1926, Schlumberger is the world’s leading provider of technology for reservoir characterization, drilling, production and processing to the oil and gas industry. Having invented wireline logging as a technique for obtaining downhole data in oil and gas wells, today Schlumberger supplies the industry’s most comprehensive range of products and services, from exploration through production, and integrated pore-to-pipeline solutions that optimize hydrocarbon recovery to deliver reservoir performance. As of December 31, 2016, the Company employed approximately 100,000 people of over 140 nationalities operating in more than 85 countries. Schlumberger has principal executive offices in Paris, Houston, London and The Hague.

On April 1, 2016, Schlumberger acquired all of the outstanding shares of Cameron International Corporation (“Cameron”), a leading provider of flow equipment products, systems and services to the oil and gas industry worldwide. The acquisition is expected to create technology-driven growth by integrating Schlumberger reservoir and well technologies with Cameron wellhead and surface equipment, flow control and processing technology. The combination of the two complementary technology portfolios provides the industry’s most comprehensive range of products and services, from exploration to production and integrated pore-to-pipeline solutions that optimize hydrocarbon recovery to deliver reservoir performance. In connection with this transaction, Schlumberger issued 138 million shares of its common stock, valued at approximately $9.9 billion as of the acquisition date, and paid cash of $2.8 billion.

Schlumberger operates in each of the major oilfield service markets, managing its business through four Groups: Reservoir Characterization, Drilling, Production and Cameron.

OneSubsea offers integration and optimization of the entire production system over the life of the field by leveraging flow control expertise and process technologies with petrotechnical expertise and reservoir and production technologies.

- Surface Systems designs and manufactures onshore and offshore platform wellhead systems and processing solutions, including valves, chokes, actuators and Christmas trees, and provides services to oil and gas operators.

- Drilling Systems provides drilling equipment and services to shipyards, drilling contractors, E&P companies and rental tool companies. The products fall into two broad categories: pressure control equipment and rotary drilling equipment. These products are designed for either onshore or offshore applications and include drilling equipment packages, blowout preventers (BOPs), BOP control systems, connectors, riser systems, valves and choke manifold systems, top drives, mud pumps, pipe handling equipment, rig designs and rig kits.

- Valves & Measurement serves portions of the upstream, midstream and downstream markets and provides valve products and measurement systems that are primarily used to control, direct and measure the flow of oil and gas as they are moved from wellheads through flow lines, gathering lines and transmission systems to refineries, petrochemical plants and industrial centers for processing.

Supporting the Groups is a global network of research and engineering centers. Through this organization, Schlumberger is committed to advanced technology programs that enhance oilfield efficiency, lower finding and producing costs, improve productivity, maximize reserve recovery and increase asset value while accomplishing these goals in a safe and environmentally sound manner.



Schlumberger’s business is also reported through four geographic Areas: North America, Latin America, Europe/CIS/Africa and Middle East & Asia. Within these Areas, a network of GeoMarket \( ^{*} \)  regions provides logistical, technical and commercial coordination.

The GeoMarket structure offers customers a single point of contact at the local level for field operations and brings together geographically focused teams to meet local needs and deliver customized solutions. The Areas and GeoMarkets are responsible for providing the most efficient and cost effective support possible to the operations.

Schlumberger primarily uses its own personnel to market its offerings. The customer base, business risks and opportunities for growth are essentially uniform across all services. Manufacturing and engineering facilities as well as research centers are shared, and the labor force is interchangeable. Technological innovation, quality of service and price differentiation are the principal methods of competition, which vary geographically with respect to the different services offered. While Schlumberger has numerous competitors, both large and small, Schlumberger believes that it is an industry leader in providing geophysical equipment and services, wireline logging, well production testing, exploration and production software, surface equipment, artificial lift, coiled-tubing services, drilling and completion fluids, solids control and waste management, drilling pressure control, drill bits, measurement-while-drilling, logging-while-drilling, directional-drilling services and surface data (mud) logging.

## GENERAL

## Intellectual Property

Schlumberger owns and controls a variety of intellectual property, including but not limited to patents, proprietary information and software tools and applications that, in the aggregate, are material to Schlumberger’s business. While Schlumberger seeks and holds numerous patents covering various products and processes, no particular patent or group of patents is considered material to Schlumberger’s business.

## Seasonality

Seasonal changes in weather and significant weather events can temporarily affect the delivery of oilfield services. For example, the spring thaw in Canada and consequent road restrictions can affect activity levels, while the winter months in the North Sea, Russia and China can produce severe weather conditions that typically result in temporarily reduced levels of activity. In addition, hurricanes and typhoons can disrupt coastal and offshore operations. Furthermore, customer spending patterns for multiclient data, software and other oilfield services and products generally result in higher activity in the fourth quarter of each year as clients seek to utilize their annual budgets.

## Customers and Backlog of Orders

For the year ended December 31, 2016, no single customer exceeded 10% of consolidated revenue. Other than WesternGeco, and the OneSubsea and Drilling Systems businesses acquired in the Cameron transaction, Schlumberger has no significant backlog due to the nature of its businesses. The WesternGeco backlog was $0.8 billion at December 31, 2016 (the vast majority of which is expected to be recognized as revenue in 2017) and $1.1 billion at December 31, 2015. The combined backlog of the OneSubsea and Drilling Systems businesses was $3.1 billion at December 31, 2016, of which approximately 60% is expected to be recognized as revenue during 2017.

## Financial Information

Financial information by business segment and geographic area for the years ended December 31, 2016, 2015 and 2014 is provided in Note 17 of the Consolidated Financial Statements.

## Item 1A. Risk Factors.

The following discussion of risk factors known to us contains important information for the understanding of our “forward-looking statements,” which are discussed immediately following Item 7A. of this Form 10-K and elsewhere. These risk factors should also be read in conjunction with Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and the Consolidated Financial Statements and related notes included in this Form 10-K.

We urge you to consider carefully the risks described below, as well as in other reports and materials that we file with the SEC and the other information included or incorporated by reference in this Form 10-K. If any of the risks described below or elsewhere in this Form 10-K were to materialize, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, the trading price of our common stock could decline and you could lose part or all of your investment. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also materially adversely affect our financial condition, results of operations and cash flows.

Demand for the majority of our services is substantially dependent on the levels of expenditures by our customers. The current significant oil and gas industry downturn has resulted in reduced demand for oilfield services, which has had, and may continue to have, a material adverse impact on our financial condition, results of operations and cash flows. If these conditions worsen or oil and gas prices do not improve, it could have a further material adverse effect on our financial condition, results of operations and cash flows.

Demand for the majority of our services depends substantially on the level of expenditures by our customers for the exploration, development and production of oil and natural gas reserves. These expenditures are generally dependent on our customers' views of future oil and natural gas prices and are sensitive to our customers' views of future economic growth and the resulting impact on demand for oil and natural gas. Since 2014, oil and gas prices have declined significantly, resulting in lower expenditures by our customers. As a result, many of our customers have reduced or delayed their oil and gas exploration and production spending, reducing the demand for our products and services and exerting downward pressure on the prices that we charge. These conditions have had, and may continue to have, an adverse impact on our financial condition.

The continued low oil and gas prices have caused a reduction in cash flows for our customers, which has had a significant adverse effect on the financial condition of some of our customers. This has resulted, in and may continue to result in, project modifications, delays and cancellations, general business disruptions, and delays in payment of, or nonpayment of, amounts that are owed to us. These effects could have a material adverse effect on our financial condition, results of operations and cash flows.

The prices for oil and natural gas have historically been volatile and can be affected by a variety of factors, including:

• demand for hydrocarbons, which is affected by general economic and business conditions;

- the ability or willingness of the Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels for oil;

• oil and gas production levels by non-OPEC countries;

• the level of excess production capacity;

• political and economic uncertainty and geopolitical unrest;

• the level of worldwide oil and gas exploration and production activity;

• access to potential resources;



• governmental policies and subsidies;

• the costs of exploring for, producing and delivering oil and gas;

• technological advances affecting energy consumption; and

• weather conditions.

There can be no assurance that the demand or pricing for oil and natural gas will follow historic patterns or recover meaningfully in the near term. Continued or worsening conditions in the oil and gas industry could have a further material adverse effect on financial condition, results of operations and cash flows.

A significant portion of our revenue is derived from our non-United States operations, which exposes us to risks inherent in doing business in each of the over 85 countries in which we operate.

Our non-United States operations accounted for approximately 80% of our consolidated revenue in 2016, 76% in 2015 and 71% in 2014. Operations in countries other than the United States are subject to various risks, including:

• volatility in political, social and economic conditions;

• exposure to expropriation of our assets or other governmental actions;

• social unrest, acts of terrorism, war or other armed conflict;

• confiscatory taxation or other adverse tax policies;

• deprivation of contract rights;

- trade and economic sanctions or other restrictions imposed by the United States, the European Union or other countries;

• restrictions under the United States Foreign Corrupt Practices Act (FCPA) or similar legislation;

• restrictions on the repatriation of income or capital;

• currency exchange controls;

• inflation; and

• currency exchange rate fluctuations and devaluations.

Our failure to comply with complex US and foreign laws and regulations could have a material adverse effect on our operations.

We are subject to complex US and foreign laws and regulations, such as the FCPA, the U.K. Bribery Act and various other anti-bribery and anti-corruption laws. We are also subject to trade control regulations and trade sanctions laws that restrict the movement of certain goods to, and certain operations in, various countries or with certain persons. Our ability to transfer people and products among certain countries is subject to maintaining required licenses and complying with these laws and regulations. The internal controls, policies and procedures, and employee training and compliance programs we have implemented to deter prohibited practices may not be effective in preventing employees, contractors or agents from violating or circumventing such internal policies or violating applicable laws and regulations. Any determination that we have violated or are responsible for violations of anti-bribery, trade control, trade sanctions or anti-corruption laws could have a material adverse effect on our financial condition. Violations of international and US laws and regulations or the loss of any required licenses may result in fines and penalties, criminal sanctions, administrative remedies or restrictions on business conduct, and could have a material adverse effect on our reputation and our business, operating results and financial condition.



Environmental compliance costs and liabilities could reduce our earnings and cash available for operations.

We are subject to increasingly stringent laws and regulations relating to importation and use of hazardous materials, radioactive materials, chemicals and explosives and to environmental protection, including laws and regulations governing air emissions, hydraulic fracturing, water discharges and waste management. We incur, and expect to continue to incur, capital and operating costs to comply with environmental laws and regulations. The technical requirements of these laws and regulations are becoming increasingly complex, stringent and expensive to implement. These laws may provide for “strict liability” for remediation costs, damages to natural resources or threats to public health and safety. Strict liability can render a party liable for damages without regard to negligence or fault on the part of the party. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances.

We use and generate hazardous substances and wastes in our operations. In addition, many of our current and former properties are, or have been, used for industrial purposes. Accordingly, we could become subject to material liabilities relating to the investigation and cleanup of potentially contaminated properties, and to claims alleging personal injury or property damage as the result of exposures to, or releases of, hazardous substances. In addition, stricter enforcement of existing laws and regulations, new laws and regulations, the discovery of previously unknown contamination or the imposition of new or increased requirements could require us to incur costs or become the basis for new or increased liabilities that could reduce our earnings and our cash available for operations.

We could be subject to substantial liability claims, which could adversely affect our financial condition, results of operations and cash flows.

The technical complexities of our operations expose us to a wide range of significant health, safety and environmental risks. Our offerings involve production-related activities, radioactive materials, chemicals, explosives and other equipment and services that are deployed in challenging exploration, development and production environments. An accident involving these services or equipment, or a failure of a product, could cause personal injury, loss of life, damage to or destruction of property, equipment or the environment, or suspension of operations. Our insurance may not protect us against liability for certain kinds of events, including events involving pollution, or against losses resulting from business interruption. Moreover, we may not be able to maintain insurance at levels of risk coverage or policy limits that we deem adequate. Any damages caused by our services or products that are not covered by insurance, or are in excess of policy limits or subject to substantial deductibles, could adversely affect our financial condition, results of operations and cash flows.

Demand for our products and services could be reduced by existing and future legislation or regulations.

Environmental advocacy groups and regulatory agencies in the United States and other countries have been focusing considerable attention on the emissions of carbon dioxide, methane and other greenhouse gases and their potential role in climate change. Existing or future legislation and regulations related to greenhouse gas emissions and climate change, as well as government initiatives to conserve energy or promote the use of alternative energy sources, may significantly curtail demand for and production of fossil fuels such as oil and gas in areas of the world where our customers operate and thus adversely affect future demand for our services. This may, in turn, adversely affect our financial condition, results of operations and cash flows.

Some international, national, state and local governments and agencies have also adopted laws and regulations or are evaluating proposed legislation and regulations that are focused on the extraction of shale gas or oil using hydraulic fracturing. Hydraulic fracturing is a stimulation treatment routinely performed on oil and gas wells in low-permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir interval to be treated, causing cracks in the target formation. Proppant, such as sand of a particular size, is mixed with the treatment fluid to keep the cracks open when the treatment is complete. Future hydraulic fracturing-related legislation or regulations could limit or ban hydraulic fracturing, or lead to operational delays and



increased costs, and therefore reduce demand for our pressure pumping services. If such additional international, national, state or local legislation or regulations are enacted, it could adversely affect our financial condition, results of operations and cash flows.

If we are unable to maintain technology leadership, this could adversely affect any competitive advantage we hold.

The oilfield service industry is highly competitive. Our ability to continually provide competitive technology and services can impact our ability to defend, maintain or increase prices for our services, maintain market share, and negotiate acceptable contract terms with our customers. If we are unable to continue to develop and produce competitive technology or deliver it to our clients in a timely and cost-competitive manner in the various markets we serve, it could adversely affect our financial condition, results of operations and cash flows.

Limitations on our ability to protect our intellectual property rights, including our trade secrets, could cause a loss in revenue and any competitive advantage we hold.

Some of our products or services, and the processes we use to produce or provide them, have been granted patent protection, have patent applications pending or are trade secrets. Our business may be adversely affected if our patents are unenforceable, the claims allowed under our patents are not sufficient to protect our technology, our patent applications are denied or our trade secrets are not adequately protected. Our competitors may be able to develop technology independently that is similar to ours without infringing on our patents or gaining access to our trade secrets, which could adversely affect our financial condition, results of operations and cash flows.

We may be subject to litigation if another party claims that we have infringed upon its intellectual property rights.

The tools, techniques, methodologies, programs and components we use to provide our services may infringe upon the intellectual property rights of others. Infringement claims generally result in significant legal and other costs and may distract management from running our core business. Royalty payments under licenses from third parties, if available, would increase our costs. Additionally, developing non-infringing technologies would increase our costs. If a license were not available, we might not be able to continue providing a particular service or product, which could adversely affect our financial condition, results of operations and cash flows.

## Failure to obtain and retain skilled technical personnel could impede our operations.

We require highly skilled personnel to operate and provide technical services and support for our business. Competition for the personnel required for our businesses intensifies as activity increases. In periods of high utilization it may become more difficult to find and retain qualified individuals. This could increase our costs or have other adverse effects on our operations.

## Severe weather conditions may adversely affect our operations.

Our business may be materially affected by severe weather conditions in areas where we operate. This may entail the evacuation of personnel and stoppage of services. In addition, if particularly severe weather affects platforms or structures, this may result in a suspension of activities. Any of these events could adversely affect our financial condition, results of operations and cash flows.

## Cybersecurity risks and threats could adversely affect our business.

We rely heavily on information systems to conduct our business. There can be no assurance that the systems we have designed to prevent or limit the effects of cyber incidents or attacks will be sufficient to prevent or detect such incidents or attacks, or to avoid a material impact on our systems when such incidents or attacks do occur. If our systems for protecting against cybersecurity risks are circumvented or breached, this could result in the loss of our intellectual property or other proprietary information, including customer data, and disruption of our business operations.

## Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis contains forward-looking statements, including, without limitation, statements relating to our plans, strategies, objectives, expectations, intentions and resources. Such forward-looking statements should be read in conjunction with our disclosures under “Item 1A. Risk Factors” of this Form 10-K.

## 2016 Executive Overview

On April 1, 2016, Schlumberger completed its acquisition of Cameron, combining their complementary portfolios into a pore-to-pipeline products and services offering for the world’s oil and gas industry. The transaction enables the creation of technology-driven growth by integrating Schlumberger reservoir and well technology with Cameron wellhead and surface equipment, flow control and processing technology.

Schlumberger revenue of $27.8 billion in 2016 represented a decrease of 22% from 2015, despite three quarters of activity from the acquired Cameron Group, which contributed $4.2 billion in revenue. Excluding the Cameron Group, revenue declined 34%. This revenue drop was due to continued weakness in exploration and production spending as a result of the deepest and longest industry crisis in more than 30 years.

The year began with Brent crude prices experiencing the sharpest fall in 30 years to $26 per barrel in January 2016, thus continuing the downturn that the oil and gas industry endured during the previous year.

Given two successive years of investment cuts, oil supply growth slowed significantly despite record OPEC production. Non-OPEC production fell sharply, largely due to a significant drop in US light tight oil production. However, robust global demand enabled the oil markets to tighten and draw down on the vast accumulation of crude and product stocks by mid-year.

The year’s end was marked by OPEC and certain non-OPEC countries, including Russia, agreeing to cut production by a combined 1.7 million barrels per day. These agreements are expected to accelerate the drawdown of stocks in 2017 and have subsequently spurred a recovery in oil prices, which reached $55 per barrel at the end of 2016.

In the natural gas markets, US production declined during 2016 as a result of the drop in gas drilling activity, while demand growth was robust throughout the year. Low gas prices during most of 2016 encouraged the power sector to continue to favor gas over coal. The year was also marked by the start-up of the Sabine Pass liquefied natural gas (LNG) plant in Texas, which exported its first shipment in early 2016, thus starting a trend that should make the US the third largest exporter of LNG by the end of 2020.

Europe continued to see modest demand growth due in part to coal plant retirements. Gas prices, however, fell to a seven-year low as supplies from Russia, Norway and North Africa reached record highs. The Asian markets continued to be in slow growth mode, albeit with slight improvements in China. Nonetheless, oversupply persisted as Australian LNG exports ramped up, driving LNG prices down even further from the already low-levels of 2015. The global outlook for LNG is largely unchanged, with continued oversupply and low prices.

Schlumberger’s financial performance in 2016 was severely impacted by the significant decrease in land-based activity, particularly in North America where the average land rig count dropped 46% as compared to the previous year. Supply overcapacity in the land market remained high for most of 2016, resulting in pricing pressure across a broad range of oilfield services. As a result, North America revenue, excluding the impact of the Cameron Group, declined 48% due to a decrease in US land revenue of 52%. Including the Cameron Group, North America revenue decreased 32%. Internationally, revenue declined 28%, excluding the impact of Cameron (17% including the Cameron Group) due to customer budget cuts, activity disruptions and a shift in revenue mix that impacted Schlumberger’s results in most basins and market segments around the world. Revenue in the



Europe, CIS & Africa Area decreased due to lower demand for exploration and development-related products and services as E&P budgets were reduced, particularly in Sub-Saharan Africa. In Latin America, revenue declined due to customer budget constraints across the Area and, more specifically, in Venezuela where operations were scaled back to align with collections. Middle East & Asia revenue decreased primarily due to reduced activity in Asia-Pacific countries, while robust activity in the Middle East was more than offset by pricing concessions.

Since the start of this downturn, and as it deepened during 2016, Schlumberger has navigated the commercial landscape by balancing pricing concessions and market share and also by proactively removing significant costs through workforce reductions, internal efficiency improvements and strong supply chain management. As a result, Schlumberger has delivered superior financial results by maintaining pretax operating margins well above 10% and delivering sufficient free cash flow to cover a range of strategic capital investments, as well as our ongoing dividend commitments.

After nine quarters of unprecedented activity decline, the business environment stabilized in the third quarter of 2016 and revenue increased slightly in the fourth quarter, suggesting that the bottom of this cycle has been reached.

Schlumberger expects the growth in E&P investments in 2017 to be led initially by land operators in North America. E&P spending surveys currently indicate that 2017 E&P investments in North America will increase by approximately 30%, which should lead to both higher activity and a recovery in service industry pricing.

Schlumberger expects the 2017 recovery in the international markets to proceed more slowly than in North America. This will likely lead to a third successive year of underinvestment, with a continued low rate of new project approvals and an accelerating production decline in the aging production base. These factors taken together are increasing the likelihood of a significant supply deficit in the medium term, which can only be avoided by a broad-based global increase in E&P spending, which is expected to start unfolding in the later parts of 2017 and leading into 2018.

Fourth-quarter revenue of $7.1 billion increased 1% sequentially. This increase was primarily driven by the Production Group, which grew 5% due to increased hydraulic fracturing activity in the Middle East and in North America land.

Fourth-quarter pretax operating margin was essentially flat sequentially at 11.4% as margin improvements in the Production and Drilling Groups were balanced by contractions in the Cameron and Reservoir Characterization Groups.

## Reservoir Characterization Group

Fourth-quarter revenue of $1.7 billion increased 1% sequentially due to the ramp-up in Testing & Process activity in Kuwait and increased software license and maintenance sales. These effects were slightly offset by the seasonal decrease in Wireline activity in Norway and Russia.

Pretax operating margin of 19% decreased 49 basis points (bps) sequentially as the increased contribution from software and maintenance sales was more than offset by the decline in high-margin Wireline activities.

## Drilling Group

Fourth-quarter revenue of $2.0 billion was flat sequentially as the continued strong directional drilling activity in North America land was offset by lower drilling activity in the International Areas. The improvement in North America revenue primarily came from increased uptake of Drilling & Measurements, Bits & Drilling Tools technologies. The lower revenue in the International Areas was primarily due to completed Drilling & Measurement projects, while the winter slowdown in Russia and Norway affected Drilling & Measurements and M-I SWACO activity.

Pretax operating margin of 12% expanded 81 bps sequentially despite revenue being flat. This was largely due to pricing improvements from greater uptake of drilling technologies on increasing activity on land in the US, which mainly affected Drilling & Measurements and Bits & Drilling Tools.

## Production Group

Fourth-quarter revenue of $2.2 billion increased 5% sequentially as a result of strong fracturing activity on unconventional resource developments on land in the Middle East, mainly in Saudi Arabia, and in North America where the land rig count and fracturing stage count increased. Revenue on land in the US increased both on volume and on a modest pricing recovery.

Pretax operating margin of 6% increased 134 bps sequentially on increased activity, which drove efficiency and better operational execution in the Middle East. The modest pricing recovery on land in the US also contributed to the margin expansion.



## Cameron Group

Fourth-quarter revenue of $1.3 billion was flat sequentially. Among the Group’s businesses, OneSubsea reported an 11% sequential increase from strong project activity and execution, while Surface Systems posted strong sales in the Middle East. These increases, however, were offset by a decline in revenue in Drilling Systems driven by a declining backlog and lower bookings. Valves & Measurement was also lower following the prior quarter’s strong international shipments.

Pretax operating margin of 14% declined 207 bps sequentially due to the drop in high-margin Drilling Systems project volume.

(4) Charges and credits are described in detail in Note 3 to the Consolidated Financial Statements.

Full-year 2016 revenue of $27.8 billion decreased 22% year-on-year. This included nine months of activity from the acquired Cameron Group, which contributed $4.2 billion of revenue.

Full-year 2016 revenue from the Reservoir Characterization and Production Groups declined by 31% and 29%, respectively, as a result of lower demand for exploration- and development-related products and services as E&P budgets were further reduced. Drilling Group revenue fell 37% due to the rig count decline in both North America and internationally.



Full-year 2016 pretax operating income margin decreased 658 bps to 12% as a result of the overall decline in activity and pervasive pricing concessions. The margin decrease was highest in the Reservoir Characterization Group, which contracted by 710 bps to 18%. Drilling Group pretax operating margin fell 710 bps to 12%, while the Production Group decreased 669 bps to 6%. The Cameron Group posted a pretax margin of 16%.

## Reservoir Characterization Group

Full-year 2016 revenue of $6.7 billion decreased 31% year-on-year primarily due to sustained cuts in exploration and discretionary spending.

Year-on-year, pretax operating margin decreased 710 bps to 18% due to reduced high-margin Wireline and Testing Services activities.

## Drilling Group

Full-year 2016 revenue of $8.6 billion decreased 37% year-on-year primarily due to the severe drop in rig count in both North America and internationally combined with pricing pressure that mainly affected Drilling & Measurements and M-I SWACO activity.

Year-on-year, pretax operating margin decreased 710 bps to 12% primarily due to the significant decline in higher-margin activities of Drilling & Measurements combined with pricing weakness.

## Production Group

Full-year 2016 revenue of $8.7 billion decreased 29% year-on-year with most of the decrease attributable to a decline in North America, particularly on Well Services pressure pumping technologies driven by activity declines and pricing pressure as the land rig count declined dramatically.

Year-on-year, pretax operating margin decreased 669 bps to 6% as a result of lower activity and increasing pricing pressure, which continued to impact North America land.

## Cameron Group

Cameron Group contributed nine-month revenue of $4.2 billion and pretax operating margin of 16%. Revenue was impacted by a declining project backlog as well as a further slowdown in North America land activity, which also affected the short-cycle businesses of the Valves & Measurement and Surface product lines.

Pretax operating margin of 16% was driven by strong project execution and manufacturing efficiency in OneSubsea and overall cost control across the Group.

Full-year 2015 revenue of $35.5 billion decreased 27% year-on-year. This decrease was primarily due to customer budget cuts and pricing concessions as customers responded to lower commodity prices. Revenue was also impacted by the fall of certain currencies against the US dollar, which accounted for approximately 20% of the revenue decline.

Full-year 2015 revenue from the Reservoir Characterization and Drilling Groups declined by 27% and 25%, respectively, as a result of lower demand as E&P budgets were reduced due to lower commodity prices. Production Group revenue fell by 29% due to activity reductions and pricing pressure as the land rig count dropped drastically in North America.

Full-year 2015 pretax operating income margin decreased 342 bps to 18% as a result of the overall decline in activity combined with the pricing pressure which most notably impacted the businesses in North America.

## Reservoir Characterization Group

Full-year 2015 revenue of $9.7 billion was 27% lower than the same period last year primarily due to sustained customer cuts in exploration and discretionary spending that impacted all Technologies.

Year-on-year, pretax operating margin decreased 295 bps to 25% as a result of an unfavorable overall revenue mix reflecting the decline in high-margin exploration activity as well as lower high-margin multiclient and software sales.



## Drilling Group

Full-year 2015 revenue of $13.6 billion was 25% lower than the previous year primarily due to the severe drop in rig count in North America, reduced activity levels and service pricing concessions internationally. Unfavorable currency effects in Russia and Venezuela also contributed to the decline.

Year-on-year, pretax operating margin decreased 228 bps to 19%, primarily due to a decrease in higher-margin activities of Drilling & Measurements as well as pricing concessions. Despite the revenue decline, prompt action on cost management and the benefit of a local cost structure that minimized the impact of unfavorable currency effects on pretax operating income helped limit the operating margin decline.

## Production Group

Full-year 2015 revenue of $12.3 billion decreased 29% year-on-year, with approximately two-thirds of the decline attributable to Well Services pressure pumping technologies as a result of activity reductions and pricing pressure as the land rig count declined dramatically in North America.

Year-on-year, pretax operating margin declined 531 bps to 13% as lower activity and increasing pricing pressure continued in North America land.

## Interest and Other Income

Interest & other income consisted of the following:

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Interest income</td><td>$ 110</td><td>$ 52</td><td>$ 51</td></tr><tr><td>Earnings of equity method investments</td><td>90</td><td>184</td><td>240</td></tr><tr><td></td><td>$ 200</td><td>$ 236</td><td>$ 291</td></tr></table>

The increase in interest income in 2016 as compared to 2015 and 2014 is primarily attributable to the higher cash and short-term investment balances as a result of the issuance of $6.0 billion of Senior Notes during the fourth quarter of 2015.

The decrease in earnings of equity method investments primarily reflects the effects of the downturn in the oil and gas industry, which has negatively impacted the majority of Schlumberger’s investments in affiliates, particularly those in North America. The decrease in 2016 also reflects the fact that Schlumberger stopped recording equity income from the OneSubsea joint venture in April 2016 as a result of Schlumberger’s acquisition of Cameron.

## Interest Expense

Interest expense of $570 million in 2016 increased by $224 million compared to 2015 primarily due to the issuance of $6.0 billion of Senior Notes during the fourth quarter of 2015 and the impact of the $3.0 billion of debt assumed in the acquisition of Cameron.

Interest expense of $346 million in 2015 decreased by $23 million compared to 2014, as the impact of a higher weighted average debt balance of approximately $0.5 billion was more than offset by a 30 bps decrease in the weighted average borrowing rates from 2.8% in 2014 to 2.5% in 2015.



## Other

Research & engineering and General & administrative expenses, as a percentage of Revenue, were as follows:

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Research &amp; engineering</td><td>3.6%</td><td>3.1%</td><td>2.5%</td></tr><tr><td>General &amp; administrative</td><td>1.4%</td><td>1.4%</td><td>1.0%</td></tr></table>

Although Research & engineering and General & administrative costs have either increased or remained flat as a percentage of Revenue in 2016 as compared to 2015, they have decreased in absolute dollar terms as a result of cost control measures that have been implemented, offset in part by the impact of the Cameron acquisition.

## Income Taxes

The Schlumberger effective tax rate was 14.6% in 2016, 25.9% in 2015, and 25.2% in 2014.

The Schlumberger effective tax rate is sensitive to the geographic mix of earnings. When the percentage of pretax earnings generated outside of North America increases, the Schlumberger effective tax rate will generally decrease. Conversely, when the percentage of pretax earnings generated outside of North America decreases, the Schlumberger effective tax rate will generally increase.

The effective tax rate for each of 2016, 2015 and 2014 was significantly impacted by the charges and credits described in Note 3 to the Consolidated Financial Statements because they were only partially tax effective. Excluding the impact of these charges and credits, the effective tax rate was 15.9% in 2016, 20.2% in 2015 and 21.9% in 2014. The decrease in the effective tax rate, excluding the impact of charges and credits, was primarily attributable to a change in the geographic mix of earnings and the favorable resolution of tax examinations in certain jurisdictions.

It is expected that the effective tax rate will gradually increase over the course of 2017 as a result of the expected improvement in activity in North America.

## Charges and Credits

Schlumberger recorded significant charges and credits in continuing operations during 2016, 2015 and 2014. These charges and credits, which are summarized below, are more fully described in Note 3 to the Consolidated Financial Statements.

(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 $850 million during 2016 and $810 million during 2015.

(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 the ability of our business 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.

(5) Refer to Note 20 to the Consolidated Financial Statements for details.



Key liquidity events during 2016, 2015 and 2014 included:

- Cash flow from operations was $6.3 billion in 2016, $8.8 billion in 2015 and $11.2 billion in 2014. The decrease in operating cash flows in each of the last two years is largely attributable to lower earnings before non-cash charges and credits and depreciation and amortization expense.

- Schlumberger paid $2.8 billion of cash in connection with the April 1, 2016 acquisition of Cameron. Additionally, as a result of the acquisition of Cameron, Schlumberger assumed $3.0 billion of debt (including a $244 million adjustment to increase Cameron’s long-term fixed rate debt to its estimated fair value) and $2.2 billion of cash and short-term investments.

- During the second quarter of 2016, Schlumberger repurchased approximately $1.4 billion of Cameron’s long-term fixed-rate debt.

- In connection with Schlumberger’s acquisition of Cameron, Cameron merged with Schlumberger Holdings Corporation (SHC), an indirect wholly-owned United States subsidiary of Schlumberger. Under the terms of the agreement, Cameron shareholders received 0.716 shares of Schlumberger Limited common stock and a cash payment of $14.44 in exchange for each Cameron share of common stock outstanding. In connection with this transaction, SHC acquired approximately 138 million shares of common stock from Schlumberger Limited and transferred those shares to Cameron’s shareholders.

In order to partially fund the purchase of the 138 million shares of common stock from Schlumberger Limited that were transferred to Cameron stockholders, SHC issued $6 billion of notes during the fourth quarter of 2015 consisting of the following:

– $500 million of 1.90% Senior Notes due 2017;

– $1.3 billion of 2.35% Senior Notes due 2018;

– $1.6 billion of 3.00% Senior Notes due 2020;

– $850 million of 3.63% Senior Notes due 2022; and

– $1.75 billion of 4.00% Senior Notes due 2025.

- On July 18, 2013, the Board approved a new $10 billion share repurchase program to be completed at the latest by June 30, 2018. Schlumberger had repurchased $9.4 billion of shares under this share repurchase program as of December 31, 2016.

The following table summarizes the activity under this share repurchase program during 2016, 2015 and 2014:

<table><tr><td rowspan="2"></td><td colspan="4">(Stated in thousands, except per share amounts)</td></tr><tr><td>Total Cost of Shares Purchased</td><td>Total Number of Shares Purchased</td><td>Average Price Paid per Share</td><td></td></tr><tr><td>2016</td><td>$     778,018</td><td>10,988.5</td><td>$     70.80</td><td></td></tr><tr><td>2015</td><td>$     2,182,180</td><td>26,751.0</td><td>$     81.57</td><td></td></tr><tr><td>2014</td><td>$     4,677,687</td><td>47,545.9</td><td>$     98.38</td><td></td></tr></table>

On January 21, 2016, the Board approved a new $10 billion share repurchase program for Schlumberger common stock. This new program will take effect once the remaining $0.6 billion authorized to be repurchased under the July 18, 2013 program is exhausted.

• Dividends paid during 2016, 2015 and 2014 were $2.6 billion, $2.4 billion and $2.0 billion, respectively.

On January 15, 2015, Schlumberger announced that the Board approved a 25% increase in the quarterly dividend, to $0.50 per share.

- Capital expenditures were $2.1 billion in 2016, $2.4 billion in 2015 and $4.0 billion in 2014. Capital expenditures are expected to be approximately $2.2 billion in 2017.



- During 2016, 2015 and 2014 Schlumberger made contributions of $174 million, $346 million and $390 million, respectively, to its postretirement benefit plans. The US pension plans were 85% funded at December 31, 2016 and 86% funded at December 31, 2015 based on the projected benefit obligation.

Schlumberger’s international defined benefit pension plans were a combined 92% funded at December 31, 2016 based on the projected benefit obligation. This compares to 93% funded at December 31, 2015.

Schlumberger expects to contribute approximately $200 million to its postretirement benefit plans in 2017, subject to market and business conditions.

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 and a lack of progress in establishing new mechanisms that address past and future accounts receivable. Schlumberger continues to experience delays in payment from its national oil company customer in Venezuela. Venezuela represented less than 5% of Schlumberger's consolidated revenue for each of the years ended December 31, 2016, 2015 and 2014. Schlumberger's net receivable balance in Venezuela as of December 31, 2016 was approximately $1.2 billion.

Although accounts receivable collections improved during the fourth quarter of 2016, Schlumberger continues to experience payment delays from many of its customers. This is attributable to the impact of lower oil and gas prices on the industry. In this regard, Ecuador now represents approximately 12% of Schlumberger’s accounts receivable balance at December 31, 2016.

Schlumberger operates in more than 85 countries. At December 31, 2016, only five of those countries individually accounted for greater than 5% of Schlumberger’s accounts receivable balances, of which only three (the United States, Ecuador and Venezuela) accounted for greater than 10%.

Schlumberger maintains a €5.0 billion Guaranteed Euro Medium Term Note program. This program provides for the issuance of various types of debt instruments such as fixed or floating rate notes in Euro, US dollar or other currencies. Schlumberger has issued €0.5 billion 1.50% Guaranteed Notes due 2019 under this program.

As of December 31, 2016, Schlumberger had $9.3 billion of cash and short-term investments on hand. Schlumberger also has separate committed debt facility agreements aggregating $6.6 billion with commercial banks, of which $4.0 billion was available and unused as of December 31, 2016. The $6.6 billion of committed debt facility agreements included $6.3 billion of committed facilities which support commercial paper programs. Schlumberger believes that these amounts are sufficient to meet future business requirements for at least the next 12 months.

The total outstanding commercial paper borrowings were $2.571 billion as of December 31, 2016 and $2.383 billion as of December 31, 2015.

(1) Excludes future payments for interest.



(2) Excludes interest on $4.9 billion of variable rate debt, which had a weighted average interest rate of 1.7% as of December 31, 2016.

(3) Represents an estimate of contractual obligations in the ordinary course of business. Although these contractual obligations are considered enforceable and legally binding, the terms generally allow Schlumberger the option to reschedule and adjust its requirements based on business needs prior to the delivery of goods.

Refer to Note 18, Pension and Other Benefit Plans, of the Consolidated Financial Statements for details regarding Schlumberger’s pension and other postretirement benefit obligations.

As discussed in Note 14, Income Taxes, of the Consolidated Financial Statements, included in the Schlumberger Consolidated Balance Sheet at December 31, 2016 is approximately $1.4 billion of liabilities associated with uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business. Due to the uncertain and complex application of tax regulations, combined with the difficulty in predicting when tax audits throughout the world may be concluded, Schlumberger cannot make reliable estimates of the timing of cash outflows relating to these liabilities.

Schlumberger has outstanding letters of credit/guarantees that relate to business performance bonds, custom/excise tax commitments, facility lease/rental obligations, etc. These were entered into in the ordinary course of business and are customary practices in the various countries where Schlumberger operates.

## Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires Schlumberger to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. The following accounting policies involve “critical accounting estimates” because they are particularly dependent on estimates and assumptions made by Schlumberger about matters that are inherently uncertain.

Schlumberger bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

## Multiclient Seismic Data

Schlumberger capitalizes the costs associated with obtaining multiclient seismic data. The carrying value of the multiclient seismic data library at December 31, 2016 and 2015 was $1.07 billion and $1.03 billion, respectively. Such costs are charged to Cost of revenue based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data. However, under no circumstances will an individual survey carry a net book value greater than a 4-year, straight-line amortized value.

The carrying value of surveys is reviewed for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Adjustments to the carrying value are recorded when it is determined that estimated future revenues, which involve significant judgment on the part of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period. For purposes of performing the annual impairment test of the multiclient library, larger surveys (which are typically prefunded by customers) are analyzed for impairment on a survey-by-survey basis and smaller surveys are analyzed based on two pools of surveys: United States and non-United States. The United States and non-United States pools were determined to be the most appropriate level at which to perform the impairment review based upon a number of factors, including (i) various macroeconomic factors that influence the ability to successfully market surveys, and (ii) the focus of the sales force and related costs.



## Allowance for Doubtful Accounts

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. Depending on how such potential issues are resolved, or if the financial condition of Schlumberger customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.

## Goodwill, Intangible Assets and Long-Lived Assets

Schlumberger records the excess of purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed as goodwill. The goodwill relating to each of Schlumberger’s reporting units is tested for impairment annually as well as when an event, or change in circumstances, indicates an impairment may have occurred.

Under generally accepted accounting principles, Schlumberger has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of one of its reporting units is greater than its carrying amount. If, after assessing the totality of events or circumstances, Schlumberger determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, there is no need to perform any further testing. However, if Schlumberger concludes otherwise, then it is required to perform the first step of a two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value.

Schlumberger has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test.

For purposes of performing the impairment test for goodwill, Schlumberger’s reporting units are its four Groups: Reservoir Characterization, Drilling, Production and Cameron. Schlumberger elected to perform the qualitative assessment described above for purposes of its annual goodwill impairment test in 2016. Based on this assessment, Schlumberger concluded that it was more likely than not that the fair value of each of its reporting units was greater than its carrying amount. Accordingly, no further testing was required.

Long-lived assets, including fixed assets, intangible assets and investments in SPM projects, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. If there is a material change in economic conditions or other circumstances influencing the estimate of future cash flows or fair value, Schlumberger could be required to recognize impairment charges in the future.

## Income Taxes

Schlumberger conducts business in more than 100 tax jurisdictions, a number of which have tax laws that are not fully defined and are evolving. Schlumberger’s tax filings are subject to regular audits by the tax authorities. These audits may result in assessments for additional taxes that are resolved with the authorities or, potentially, through the courts. Schlumberger recognizes the impact of a tax position in its financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, the ultimate resolution of audits may



result in liabilities that could be materially different from these estimates. In such an event, Schlumberger will record additional tax expense or tax benefit in the period in which such resolution occurs.

## Percentage-of-Completion Revenue Recognition

Schlumberger uses the percentage-of-completion method to account for certain long-term construction-type contracts, primarily in the Cameron Group. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work progresses on each contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs.

The estimate of total project costs has a significant impact on both the amount of revenue recognized as well as the related profit on a project. Revenue and profits on contracts can also be significantly affected by change orders and claims. Profits are recognized based on the estimated project profit multiplied by the percentage complete. Due to the nature of these projects, adjustments to estimates of contract revenue and total contract costs are often required as work progresses. Any expected losses on a project are recorded in full in the period in which they become probable.

Approximately 6% of Schlumberger’s revenue in 2016 was recognized under the percentage-of-completion method.

## Pension and Postretirement Benefits

Schlumberger’s pension and postretirement benefit obligations are described in detail in Note 18 to the Consolidated Financial Statements. The obligations and related costs are calculated using actuarial concepts, which include critical assumptions related to the discount rate, expected rate of return on plan assets and medical cost trend rates. These assumptions are important elements of expense and/or liability measurement and are updated on an annual basis, or upon the occurrence of significant events.

The discount rate that Schlumberger uses reflects the prevailing market rate of a portfolio of high-quality debt instruments with maturities matching the expected timing of payment of the related benefit obligations. The following summarizes the discount rates utilized by Schlumberger for its various pension and postretirement benefit plans:

- The discount rate utilized to determine the liability for Schlumberger’s United States pension plans and postretirement medical plan was 4.20% at December 31, 2016 and 4.50% at December 31, 2015.

- The weighted-average discount rate utilized to determine the liability for Schlumberger’s international pension plans was 4.13% at December 31, 2016 and 4.36% at December 31, 2015.

- The weighted-average discount rate utilized to determine expense for Schlumberger’s United States pension plans and postretirement medical plan decreased from 4.85% in 2015 to 4.15% in 2016.

- The weighted-average discount rate utilized to determine expense for Schlumberger’s international pension plans increased from 4.07% in 2015 to 4.36% in 2016.

The expected rate of return for Schlumberger’s retirement benefit plans represents the average rate of return expected to be earned on plan assets over the period that benefits included in the benefit obligation are expected to be paid. The expected rate of return for Schlumberger’s United States pension plans has been determined based upon expected rates of return for the investment portfolio, with consideration given to the distribution of investments by asset class and historical rates of return for each individual asset class. The weighted average expected rate of return on plan assets for the United States pension plans was 7.25% in both 2016 and 2015. The weighted average expected rate of return on plan assets for the international pension plans was 7.40% in both 2016 and 2015. A lower expected rate of return would increase pension expense.

Schlumberger’s medical cost trend rate assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. The overall medical cost trend rate assumption utilized to



determine the 2016 postretirement medical expense was 7.50% graded to 5.0% over the next ten years. The overall medical trend rate assumption utilized to determine the postretirement medical liability at December 31, 2016 was 7.25% graded to 5.0% over the next ten years.

The following illustrates the sensitivity to changes in certain assumptions, holding all other assumptions constant, for Schlumberger’s United States and international pension plan:

## Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Schlumberger is subject to market risks primarily associated with changes in foreign currency exchange rates and interest rates.

As a multinational company, Schlumberger operates in more than 85 countries. Schlumberger’s functional currency is primarily the US dollar. Approximately 77% of Schlumberger’s revenue in 2016 was denominated in US dollars. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies. Therefore, when the US dollar weakens in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar-reported expenses will increase.

Schlumberger maintains a foreign-currency risk management strategy that uses derivative instruments to manage the impact of changes in foreign exchange rates on its earnings. Schlumberger enters into foreign currency forward contracts to provide a hedge against currency fluctuations on certain monetary assets and liabilities, and certain expenses denominated in currencies other than the functional currency.

A 10% appreciation in the US dollar from the December 31, 2016 market rates would increase the unrealized value of Schlumberger’s forward contracts by $47 million. Conversely, a 10% depreciation in the US dollar from the December 31, 2016 market rates would decrease the unrealized value of Schlumberger’s forward contracts by $57 million. In either scenario, the gain or loss on the forward contract would be offset by the gain or loss on the underlying transaction, and therefore, would have no impact on future earnings.

At December 31, 2016, contracts were outstanding for the US dollar equivalent of $5.5 billion in various foreign currencies of which $1.1 billion related to hedges of debt balances denominated in currencies other than the functional currency.



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. At December 31, 2016, Schlumberger had fixed rate debt aggregating approximately $14.7 billion and variable rate debt aggregating approximately $4.9 billion, before considering the effects of cross currency swaps.

Schlumberger’s exposure to interest rate risk associated with its debt is also partially mitigated by its investment portfolio. Both Short-term investments and Fixed income investments, held to maturity, which totaled approximately $6.6 billion at December 31, 2016, are comprised primarily of money market funds, time deposits, certificates of deposit, commercial paper, bonds and notes, substantially all of which are denominated in US dollars. The average return on investments was 0.9% in 2016.

## Forward-looking Statements

This Form 10-K and other statements we make contain “forward-looking statements” within the meaning of the federal securities laws, which include any statements that are not historical facts, such as our forecasts or expectations regarding business outlook; growth for Schlumberger as a whole and for each of its segments (and for specified products or geographic areas within each segment); oil and natural gas demand and production growth; rig count; oil and natural gas prices; improvements in operating procedures and technology; capital expenditures by Schlumberger and the oil and gas industry; the business strategies of Schlumberger’s customers; the anticipated benefits of the Cameron transaction; targeted mergers and acquisitions; the success of Schlumberger’s joint 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; demand for our integrated services and new technologies; the inability to reduce the cost-per-barrel of hydrocarbon developments; Schlumberger’s future cash flows; general economic, political, security and business conditions in key regions of the world; country risk; pricing erosion; foreign exchange rates; 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 ability to realize expected synergies from the Cameron acquisition; the inability to retain key employees; and other risks and uncertainties detailed in the Risk Factors section of this Form 10-K and other filings that we make with the Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of such a development change), 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.

# Notes to Consolidated Financial Statements

## 1. Business Description

Schlumberger Limited (Schlumberger N.V., incorporated in Curaçao) and its consolidated subsidiaries (collectively, “Schlumberger”) comprise the world’s leading supplier of technology for reservoir characterization, drilling, production and processing to the oil and gas industry.

## 2. Summary of Accounting Policies

The Consolidated Financial Statements of Schlumberger have been prepared in accordance with accounting principles generally accepted in the United States of America.

## Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable; revenue recognized under the percentage-of-completion method; recoverability of fixed assets, goodwill, intangible assets, Schlumberger Production Management investments and investments in affiliates; income taxes; multiclient seismic data; contingencies and actuarial assumptions for employee benefit plans. Schlumberger bases its estimates on historical experience and other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

## Revenue Recognition

Schlumberger recognizes revenue based upon purchase orders, contracts or other persuasive evidence of an arrangement with the customer that include fixed or determinable prices provided that collectibility is reasonably assured. Revenue is recognized for services when they are rendered. Revenue is recognized for products upon delivery and when the customer assumes the risks and rewards of ownership.

Revenue is recognized for certain long-term construction-type contracts, primarily in the Cameron Group, based on the percentage-of-completion method. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work progresses on each such contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs. Any expected losses on a project are recorded in full in the period in which they become probable. Progress billings are generally issued upon completion of certain phases of work as stipulated in the contract. Revenue in excess of billings is included within Receivables less allowance for doubtful accounts in the Consolidated Balance Sheet. Billings and cash collections in excess of revenue recognized on contracts are included within Accounts payable and accrued liabilities in the Consolidated Balance Sheet.

Revenue from seismic contract services performed on a dayrate basis is recognized as the service is performed. Revenue from other services, including pre-funded multiclient surveys, is recognized as the seismic data is acquired and/or processed on a proportionate basis as work is performed. This method requires revenue to be recognized based upon quantifiable measures of progress, such as square kilometers acquired. Multiclient data surveys are licensed or sold to customers on a non-transferable basis. Revenue from sales of completed multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers with access to such data.



Revenue is occasionally generated from contractual arrangements that include multiple deliverables. Revenue from these arrangements is recognized as each item is delivered based on its relative fair value, provided that the delivered items have stand-alone value to the customer.

Revenue derived from the sale of licenses of Schlumberger software may include installation, maintenance, consulting and training services. If services are not essential to the functionality of the software, the revenue for each element of the contract is recognized separately based on its respective vendor specific objective evidence of fair value when all of the following conditions are met: a signed contract is obtained, delivery has occurred, the fee is fixed or determinable and collectibility is probable.

## Short-term and Fixed Income Investments

The Consolidated Balance Sheet reflects the Schlumberger investment portfolio separated between current and long term, based on maturity. Both Short-term investments and Fixed Income Investments, held to maturity are comprised primarily of money market funds, time deposits, certificates of deposit, commercial paper, bonds and notes, substantially all of which are denominated in US dollars. Under normal circumstances Schlumberger intends to hold such investments until maturity, with the exception of $503 million of Short-term investments at December 31, 2016 that are considered available-for-sale and stated at fair value. All other investments are stated at cost plus accrued interest, which approximates market. The unrealized gains/losses in investments designated as available-for-sale were not significant at December 31, 2016.

For purposes of the Consolidated Statement of Cash Flows, Schlumberger does not consider Short-term investments to be cash equivalents.

Fixed Income Investments, held to maturity at December 31, 2016 of $238 million mature as follows: $225 million in 2018 and $13 million in 2019.

## Investments in Affiliated Companies

Investments in companies in which Schlumberger does not have a controlling financial interest, but over which it has significant influence are accounted for using the equity method. Schlumberger’s share of the after-tax earnings of equity method investees is included in Interest and other income. Investments in privately held companies in which Schlumberger does not have the ability to exercise significant influence are accounted for using the cost method. Investments in publicly traded companies in which Schlumberger does not have significant influence are accounted for as available-for-sale marketable securities. These marketable securities are reported at fair value, based on quoted market prices, with unrealized gains and losses reported as a component of Accumulated other comprehensive loss. The fair value of these marketable securities was $59 million at December 31, 2016 ($41 million at December 31, 2015). The cost basis of these marketable securities was $41 million at both December 31, 2016 and 2015.

Equity and cost method investments as well as investments in publicly traded companies are classified as Investments in Affiliated Companies in the Consolidated Balance Sheet.

## Multicient Seismic Data

Schlumberger’s multicient library consists of completed and in-process seismic surveys that are licensed on a nonexclusive basis. Schlumberger capitalizes costs directly incurred in acquiring and processing the multicient seismic data. Such costs are charged to Cost of revenue based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data. However, under no circumstance will an individual survey carry a net book value greater than a 4-year, straight-line amortized value.

The carrying value of the multicient library is reviewed for impairment annually as well as when an event or change in circumstance indicating impairment may have occurred. Adjustments to the carrying value are



recorded when it is determined that estimated future cash flows, which involve significant judgment on the part of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period.

## Schlumberger Production Management

Schlumberger Production Management (SPM) projects are focused on developing and managing production on behalf of Schlumberger’s clients under long-term agreements. Schlumberger will invest its own services, products and in some cases cash, into the field development activities and operations. Although in certain arrangements Schlumberger is paid for a portion of the services or products it provides, generally Schlumberger will not be paid at the time of providing its services or upon delivery of its products. Instead, Schlumberger is compensated based upon cash flow generated or on a fee-per-barrel basis. This may include certain arrangements whereby Schlumberger is only compensated based upon incremental production it helps deliver above a mutually agreed baseline.

Schlumberger capitalizes its cash investments in a project as well as the direct costs associated with providing services or products for which Schlumberger will be compensated when the related production is achieved. Revenue is recognized as the related production is achieved. These capitalized investments are amortized to the Consolidated Statement of Income as the related oil production is achieved based on the units of production method, whereby each unit produced is assigned a pro-rata portion of the unamortized costs based on estimated total production, resulting in a matching of revenue with the applicable costs. Amortization expense relating to these capitalized investments was $449 million, $317 million and $315 million in 2016, 2015 and 2014, respectively.

The unamortized portion of Schlumberger’s investments in SPM projects was $2.458 billion and $1.829 billion at December 31, 2016 and 2015, respectively. These amounts are included within Other Assets in Schlumberger’s Consolidated Balance Sheet.

## Concentration of Credit Risk

Schlumberger’s assets that are exposed to concentrations of credit risk consist primarily of cash, short-term investments, fixed income investments held to maturity, receivables from clients and derivative financial instruments. Schlumberger places its cash, short-term investments and fixed income investments held to maturity with financial institutions and corporations and limits the amount of credit exposure with any one of them. Schlumberger regularly evaluates the creditworthiness of the issuers in which it invests. By using derivative financial instruments to hedge certain exposures, Schlumberger exposes itself to some credit risk. Schlumberger minimizes this credit risk by entering into transactions with high-quality counterparties, limiting the exposure to each counterparty and monitoring the financial condition of its counterparties.

Schlumberger operates in more than 85 countries and as such, its accounts receivable are spread over many countries and customers. The United States, Venezuela and Ecuador each represented approximately 11%, 12% and 12% of Schlumberger’s accounts receivable balance at December 31, 2016. No other country accounted for greater than 10% of Schlumberger’s accounts receivable balance. Schlumberger has continued to experience delays in payment from its national oil company customer in Venezuela. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectibility and performs ongoing credit evaluations of its customers’ financial condition. If the financial condition of its customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.



## Earnings per Share

The following is a reconciliation from basic to diluted earnings per share from continuing operations of Schlumberger for each of the last three years:

<table><tr><td rowspan="2"></td><td colspan="4">(Stated in millions, except per share amounts)</td></tr><tr><td>Schlumberger Income (Loss) from Continuing Operations</td><td>Average Shares Outstanding</td><td>Earnings (Loss) per Share from Continuing Operations</td><td></td></tr><tr><td>2016:</td><td></td><td></td><td></td><td></td></tr><tr><td>Basic</td><td>$ (1,687)</td><td>1,357</td><td>$ (1.24)</td><td></td></tr><tr><td>Assumed exercise of stock options</td><td>-</td><td>-</td><td></td><td></td></tr><tr><td>Unvested restricted stock</td><td>-</td><td>-</td><td></td><td></td></tr><tr><td>Diluted</td><td>$ (1,687)</td><td>1,357</td><td>$ (1.24)</td><td></td></tr><tr><td>2015:</td><td></td><td></td><td></td><td></td></tr><tr><td>Basic</td><td>$ 2,072</td><td>1,267</td><td>$ 1.63</td><td></td></tr><tr><td>Assumed exercise of stock options</td><td>-</td><td>4</td><td></td><td></td></tr><tr><td>Unvested restricted stock</td><td>-</td><td>4</td><td></td><td></td></tr><tr><td>Diluted</td><td>$ 2,072</td><td>1,275</td><td>$ 1.63</td><td></td></tr><tr><td>2014:</td><td></td><td></td><td></td><td></td></tr><tr><td>Basic</td><td>$ 5,643</td><td>1,295</td><td>$ 4.36</td><td></td></tr><tr><td>Assumed exercise of stock options</td><td>-</td><td>9</td><td></td><td></td></tr><tr><td>Unvested restricted stock</td><td>-</td><td>4</td><td></td><td></td></tr><tr><td>Diluted</td><td>$ 5,643</td><td>1,308</td><td>$ 4.31</td><td></td></tr></table>

Employee stock options to purchase 47 million shares of common stock as well as 5 million unvested restricted stock units were outstanding at December 31, 2016, but were not included in the computation of diluted loss per share as their effect, if included, would have been anti-dilutive.

Employee stock options to purchase 20 million and 5 million shares of common stock at December 31, 2015 and 2014, respectively, were outstanding but not included in the computation of diluted earnings per share because the option exercise price was greater than the average market price of the common stock, and therefore the effect on diluted earnings per share would have been anti-dilutive.

## Recently Issued 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 principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a 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.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which requires that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. Schlumberger adopted this ASU in the fourth quarter of 2016 on a prospective basis.

## Reclassifications

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

## 3. Charges and Credits

Schlumberger recorded the following charges and credits in continuing operations during 2016, 2015 and 2014:

## 2016

- Schlumberger reduced its headcount during the second quarter of 2016 as a result of persistent unfavorable oil and gas industry market conditions and the expected impact on customer activity levels. Schlumberger recorded a $646 million charge during the second quarter of 2016 associated with this headcount reduction. During the fourth quarter of 2016, Schlumberger decided to further reduce its headcount in order to streamline its support cost structure. Schlumberger recorded an additional $234 million charge during the fourth quarter associated with these actions. Approximately $400 million of the costs remain unpaid as of December 31, 2016.

- During the fourth quarter of 2016, Schlumberger recorded $302 million of restructuring charges consisting of the following: $165 million of facility closure costs due to the expected sale of certain owned properties and the termination of certain facility leases; $98 million of asset write-offs associated with exiting certain activities; and $39 million of contract termination costs.

- During the fourth quarter of 2016, the Central Bank of Egypt took the decision to float its currency and the Egyptian pound devalued relative to the US dollar. As a result, Schlumberger recorded a $63 million devaluation charge during the fourth 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 also took certain decisions that resulted in the following impairment and other charges during the second quarter of 2016:

- $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 underutilized equipment.

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

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

- $55 million of other restructuring 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.



- In connection with Schlumberger’s April 2016 acquisition of Cameron International Corporation (“Cameron”) (see Note 4 – Acquisitions), Schlumberger recorded $648 million of charges consisting of the following: $299 million relating to the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value; $83 million relating to employee benefits for change-in-control arrangements and retention bonuses; $45 million of transaction costs, including advisory and legal fees; $61 million of facility closure costs, and $160 million of other merger and integration-related costs. These amounts are classified in Merger & integration in the Consolidated Statement of Income.

The following is a summary of these charges and credits, of which $3.172 billion were classified as Impairments & other and $648 million were classified as Merger & integration in the Consolidated Statement of Income:

(Stated in millions)

<table><tr><td></td><td>Pretax</td><td>Tax</td><td>Net</td></tr><tr><td>Workforce reductions</td><td>$ 880</td><td>$ 69</td><td>$ 811</td></tr><tr><td>Other fixed asset impairments</td><td>684</td><td>52</td><td>632</td></tr><tr><td>Inventory write-downs</td><td>616</td><td>49</td><td>567</td></tr><tr><td>Amortization of inventory fair value adjustment</td><td>299</td><td>90</td><td>209</td></tr><tr><td>Facility closure costs</td><td>226</td><td>53</td><td>173</td></tr><tr><td>North America pressure pumping asset impairments</td><td>209</td><td>67</td><td>142</td></tr><tr><td>Multiclient seismic data impairment</td><td>198</td><td>62</td><td>136</td></tr><tr><td>Facility impairments</td><td>165</td><td>58</td><td>107</td></tr><tr><td>Other merger and integration-related</td><td>160</td><td>28</td><td>132</td></tr><tr><td>Costs associated with exiting certain activities</td><td>98</td><td>23</td><td>75</td></tr><tr><td>Merger-related employee benefits</td><td>83</td><td>13</td><td>70</td></tr><tr><td>Currency devaluation loss in Egypt</td><td>63</td><td>-</td><td>63</td></tr><tr><td>Other restructuring charges</td><td>55</td><td>-</td><td>55</td></tr><tr><td>Professional fees</td><td>45</td><td>10</td><td>35</td></tr><tr><td>Contract termination costs</td><td>39</td><td>9</td><td>30</td></tr><tr><td></td><td>$ 3,820</td><td>$ 583</td><td>$ 3,237</td></tr></table>

## 2015

- Schlumberger reduced its headcount during the first quarter of 2015 as a result of the severe fall in activity in North America, combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. Schlumberger recorded a $390 million charge during the first quarter associated with this headcount reduction as well as an incentivized leave of absence program. Based on the activity outlook for 2016, as well as to further streamline its support structure, Schlumberger decided to further reduce its headcount and expand its incentivized leave of absence program during the fourth quarter of 2015. Schlumberger recorded an additional $530 million charge during the fourth quarter associated with these actions.

- As a result of unfavorable oil and gas industry market conditions that continued to deteriorate and their impact on the activity outlook, Schlumberger determined that the carrying values of certain assets were no longer recoverable and also took certain decisions that resulted in the following impairment and restructuring charges during the fourth quarter of 2015:

- $776 million of fixed asset impairments primarily related to underutilized pressure pumping and other equipment in North America, as well as certain lower-tier drilling rigs.



- $269 million to write-down the carrying value of certain inventory, primarily in North America.

- $182 million to reduce the carrying value of an investment in an SPM project to its estimated fair value, as a result of the decline in commodity prices and considering this project is approaching the end of its contractual term.

- $177 million associated with certain of Schlumberger’s owned and leased facilities, including the expected sale of certain properties and the termination of certain leases.

- $77 million relating to assets that are no longer recoverable as a result of geopolitical issues in certain countries in the Middle East.

- $41 million relating to contract termination costs.

- $84 million of other charges associated with current market conditions, including $40 million relating to an other-than-temporary impairment of marketable securities and $15 million relating to the impairment of an equity-method investment.

Certain of these impairment charges were estimated based on the projected present value of future cash flows, which included unobservable inputs that required significant judgments.

- In February 2015, the Venezuelan government replaced the SICAD II exchange rate (described in further detail below) with a new foreign exchange market system known as SIMADI. The SIMADI exchange rate was approximately 192 Venezuelan Bolivares futures to the US dollar as of March 31, 2015. As a result, Schlumberger recorded a $49 million devaluation charge during the first quarter of 2015, reflecting the adoption of the SIMADI exchange rate.

This change results in a reduction in the US dollar reported amount of local currency denominated revenues, expenses and, consequently, income before taxes and net income in Venezuela. If Schlumberger had applied an exchange rate of 192 Venezuelan Bolivares futures to the US dollar throughout 2014, it would have reduced Schlumberger earnings by approximately $0.09 per share.

The following is a summary of these charges and credits, all of which were classified as Impairments & other in the Consolidated Statement of Income:

<table><tr><td rowspan="2"></td><td rowspan="2">Pretax</td><td rowspan="2">Tax</td><td rowspan="2">Net</td></tr><tr></tr><tr><td>Workforce reductions</td><td>920</td><td>107</td><td>813</td></tr><tr><td>Fixed asset impairments</td><td>776</td><td>141</td><td>635</td></tr><tr><td>Inventory write-downs</td><td>269</td><td>27</td><td>242</td></tr><tr><td>Impairment of SPM project</td><td>182</td><td>36</td><td>146</td></tr><tr><td>Facility closures</td><td>177</td><td>37</td><td>140</td></tr><tr><td>Geopolitical events</td><td>77</td><td>-</td><td>77</td></tr><tr><td>Currency devaluation loss in Venezuela</td><td>49</td><td>-</td><td>49</td></tr><tr><td>Contract termination costs</td><td>41</td><td>2</td><td>39</td></tr><tr><td>Other</td><td>84</td><td>7</td><td>77</td></tr><tr><td></td><td>$ 2,575</td><td>$ 357</td><td>$ 2,218</td></tr></table>

## 2014

- During the fourth quarter of 2014, Schlumberger restructured its WesternGeco marine seismic fleet in order to lower its operating costs. Three previous-generation acquisition vessels with lower towing capacity and higher operating costs will be converted to source vessels, allowing for the termination of two third-party source vessel leases and the retirement of two owned source vessels.

As a result of this restructuring, Schlumberger performed an impairment test and determined that the carrying values of certain of its vessels exceeded their respective fair values by $590 million. This



impairment charge related to the six Explorer-class vessels that were acquired at a premium in Schlumberger’s 2007 acquisition of Eastern Echo Holdings Plc. The fair value of these vessels was estimated primarily based on the replacement cost method, which was largely based on unobservable inputs that required significant judgments.

In addition to the $590 million impairment charge relating to these six vessels, Schlumberger also recorded an $85 million impairment charge relating to a seismic intangible asset and $131 million of other charges primarily related to lease termination costs and other seismic assets as a result of the restructuring. Schlumberger did not incur any significant cash expenditures as a result of these charges.

- During 2014, Venezuela enacted certain changes to its foreign exchange system such that, in addition to the official rate of 6.3 Venezuelan Bolivares futures per US dollar, there were two other legal exchange rates that could be obtained via different exchange rate mechanisms at the time. These changes included the expansion of what was known as the SICAD I auction rate and the introduction of the SICAD II auction process. The SICAD I and SICAD II exchange rates were approximately 11 and 50 Venezuelan Bolivares futures to the US dollar, respectively, at December 31, 2014.

Schlumberger had historically applied the official exchange rate to remeasure local currency transactions and balances into US dollars. Effective December 31, 2014, Schlumberger concluded that it was appropriate to apply the SICAD II exchange rate as it believed that rate best represented the economics of Schlumberger’s business activity in Venezuela. As a result, Schlumberger recorded a $472 million devaluation charge during the fourth quarter of 2014.

- In response to lower commodity pricing and anticipated lower exploration and production spending in 2015, Schlumberger decided during the fourth quarter of 2014 to reduce its overall headcount primarily to better align with anticipated activity levels for 2015. As a result of these reductions, Schlumberger recorded a charge of $296 million in the fourth quarter of 2014.

- During the fourth quarter of 2014, Schlumberger determined that, primarily as a result of the recent decline in commodity prices, the carrying value of its investment in an SPM development project in the Eagle Ford Shale was in excess of its fair value. Accordingly, Schlumberger recorded a $199 million impairment charge. The fair value of this investment was estimated based on the projected present value of future cash flows.

The following is a summary of these charges, all of which were classified as Impairments & other in the Consolidated Statement of Income:

<table><tr><td rowspan="2"></td><td colspan="4">(Stated in millions)</td></tr><tr><td>Pretax</td><td>Tax</td><td>Net</td><td></td></tr><tr><td>WesternGeco restructuring</td><td>$ 806</td><td>$ 25</td><td>$ 781</td><td></td></tr><tr><td>Currency devaluation loss in Venezuela</td><td>472</td><td>-</td><td>472</td><td></td></tr><tr><td>Workforce reduction</td><td>296</td><td>37</td><td>259</td><td></td></tr><tr><td>Impairment of SPM project</td><td>199</td><td>72</td><td>127</td><td></td></tr><tr><td></td><td>$ 1,773</td><td>$ 134</td><td>$ 1,639</td><td></td></tr></table>

## 4. Acquisitions

## 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. The acquisition is expected to create technology-driven growth by integrating Schlumberger reservoir and well technologies with Cameron



wellhead and surface equipment, flow control and processing technology. The combination of the two complementary technology portfolios provides the industry’s most comprehensive range of products and services, from exploration to production and integrated pore-to-pipeline solutions that optimize hydrocarbon recovery to deliver reservoir performance.

Under the terms of the merger agreement, Cameron became a wholly-owned subsidiary of Schlumberger. Each share of Cameron common stock issued and outstanding immediately prior to the effective time of the merger was converted into the right to receive 0.716 shares of Schlumberger stock and $14.44 in cash.

## Calculation of Consideration Transferred

The following details the fair value of the consideration transferred to effect the acquisition of Cameron:

<table><tr><td colspan="3">(stated in millions, except exchange ratio and per share amounts)</td></tr><tr><td>Equity consideration:</td><td></td><td></td></tr><tr><td>Number of shares of Cameron stock outstanding</td><td>192</td><td></td></tr><tr><td>Exchange ratio</td><td>0.716</td><td></td></tr><tr><td>Schlumberger shares of common stock issued</td><td>138</td><td></td></tr><tr><td>Schlumberger closing stock share price on April 1, 2016</td><td>72.12</td><td></td></tr><tr><td>Equity consideration</td><td></td><td>$ 9,924</td></tr><tr><td>Cash consideration:</td><td></td><td></td></tr><tr><td>Number of shares of Cameron stock outstanding</td><td>192</td><td></td></tr><tr><td>Cash consideration per Cameron share</td><td>14.44</td><td></td></tr><tr><td>Cash consideration</td><td></td><td>2,776</td></tr><tr><td>Other:</td><td></td><td></td></tr><tr><td>Fair value of replacement equity awards</td><td></td><td>103</td></tr><tr><td>Total fair value of the consideration transferred</td><td></td><td>$ 12,803</td></tr></table>

Certain amounts reflect rounding adjustments



The following amounts represent the preliminary estimates of the fair value of assets acquired and liabilities assumed in the merger. The final determination of fair value for certain assets and liabilities will be completed as soon as the information necessary to complete the analysis is obtained. These amounts, which are not expected to differ materially from current estimates, will be finalized in the first quarter of 2017.

(1) Schlumberger recorded an adjustment of $299 million to write-up the acquired inventory to its estimated fair value. Schlumberger’s 2016 cost of sales reflected this increased valuation.

(2) In connection with the merger, Schlumberger assumed all of the debt obligations of Cameron, including its $2.75 billion of fixed rate notes. Schlumberger recorded a $244 million adjustment to increase the carrying amount of these notes to their estimated fair value. This adjustment is being amortized as a reduction of interest expense over the remaining term of the respective obligations.

(3) In connection with the acquisition accounting, Schlumberger provided deferred taxes related to, among other items, the estimated fair value adjustments for acquired inventory, intangible assets and assumed debt obligations.

(4) Prior to the completion of the merger, Cameron and Schlumberger operated OneSubsea, a joint venture that manufactured and developed products, systems and services for the subsea oil and gas market, which was 40% owned by Schlumberger and 60% owned by Cameron. OneSubsea is now owned 100% by Schlumberger. As a result of obtaining control of this joint venture, Schlumberger was required to remeasure its previously held equity interest in the joint venture to its acquisition-date fair value. Schlumberger determined that the estimated fair value of its previously held equity interest approximated its carrying value. Accordingly, Schlumberger did not recognize any gain or loss on this transaction.

(5) The goodwill recognized is primarily attributable to expected synergies that will result from combining the operations of Schlumberger and Cameron, as well as intangible assets which do not qualify for separate recognition. The amount of goodwill that is deductible for income tax purposes is not significant.



## Supplemental Pro Forma Financial Information

Cameron’s results of operations have been included in Schlumberger’s financial statements for periods subsequent to the closing of the acquisition on April 1, 2016. Businesses acquired from Cameron contributed revenues of approximately $4 billion and pretax operating income of approximately $0.7 billion for the period from April 1, 2016 through December 31, 2016.

The following supplemental pro forma results of operations assume that Cameron had been acquired on 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 amortization expense, interest expense and income taxes resulting from purchase accounting. The pro forma results for the year ended December 31, 2016 reflect adjustments to exclude after-tax merger and integration costs of $285 million and after-tax charges relating to the amortization of the inventory fair value adjustment of $209 million. As required by generally accepted accounting principles, the pro forma results for the year ended December 31, 2015 have been adjusted to include after-tax adjustments for merger and integration costs of $285 million and the after-tax charges relating to the amortization of the inventory fair value adjustment of $209 million.

The supplemental pro forma financial information presented below is unaudited and 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.

(1) Schlumberger maintains a €5.0 billion Guaranteed Euro Medium Term Note program that provides for the issuance of various types of debt instruments such as fixed or floating rate notes in euro, US dollar or other currencies. Schlumberger issued €0.5 billion 1.50% Guaranteed Notes due 2019 under this program in 2013.

(2) Represents long-term fixed rate debt obligations assumed in connection with the acquisition of Cameron, net of amounts repurchased subsequent to the closing of the transaction.

Schlumberger Limited fully and unconditionally guarantees the securities issued by certain of its subsidiaries, including securities issued by Schlumberger Investment SA, a wholly-owned finance subsidiary of Schlumberger.

At December 31, 2016, Schlumberger had separate committed debt facility agreements aggregating $6.6 billion with commercial banks, of which $4.0 billion was available and unused. This included $6.3 billion of committed facilities which support commercial paper programs in the United States and Europe, of which $1.0 billion matures in February 2017, $1.8 billion matures in July 2018, $1.5 billion matures in November 2020, and $2.0 billion matures in February 2021. Interest rates and other terms of borrowing under these lines of credit vary from country to country.

Commercial paper borrowings are classified as long-term debt to the extent they are backed up by available and unused committed credit facilities maturing in more than one year and to the extent it is Schlumberger’s intent to maintain



these obligations for longer than one year. Borrowings under the commercial paper program at December 31, 2016 were $2.6 billion, of which $2.4 billion was classified within Long-term debt and $0.2 billion was classified in Long-term debt – current portion in the Consolidated Balance Sheet. At December 31, 2015, borrowings under the commercial paper program were $2.4 billion, of which $1.0 billion was classified within Long-term debt and $1.4 billion was classified in Long-term debt – current portion in the Consolidated Balance Sheet.

The weighted average interest rate on variable rate debt as of December 31, 2016 was 1.7%.

Long-term Debt as of December 31, 2016, is due as follows: $2.0 billion in 2018, $1.3 billion in 2019, $2.6 billion in 2020, $4.8 billion in 2021, $2.0 billion in 2022, $1.6 billion in 2023, $1.8 billion in 2025 and $0.4 billion thereafter.

The fair value of Schlumberger’s Long-term Debt at December 31, 2016 and December 31, 2015 was $16.8 billion and $14.4 billion, respectively, and was estimated based on quoted market prices.

## 11. Derivative Instruments and Hedging Activities

Schlumberger is exposed to market risks related to fluctuations in interest rates and foreign currency exchange 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 December 31, 2016, Schlumberger had fixed rate debt aggregating $14.1 billion and variable rate debt aggregating $5.5 billion, after taking into account the effect of the swap.

Short-term investments and Fixed income investments, held to maturity, totaled $6.6 billion at December 31, 2016. 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. Approximately 77% of Schlumberger’s revenues in 2016 was denominated in US dollars. 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 December 31, 2016, Schlumberger recognized a cumulative net $19 million loss in Accumulated other comprehensive loss relating to revaluation of foreign currency forward contracts 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 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 are recorded on the Consolidated Balance Sheet and changes in the fair value are recognized in the Consolidated Statement of Income as are changes in the fair value of the hedged item. Transaction losses of $93 million, $76 million and $539 million, net of related hedging activities, were recognized in the Consolidated Statement of Income in 2016, 2015 and 2014, respectively. Included in these amounts are $63 million relating to Egypt in 2016, $49 million relating to Venezuela in 2015 and $472 million relating to Venezuela in 2014. See Note 3 – Charges and Credits for further details.

At December 31, 2016, contracts were outstanding for the US dollar equivalent of $5.5 billion in various foreign currencies, of which $1.1 billion relates to hedges of debt denominated in currencies other than the functional currency.

## 13. Stock-based Compensation Plans

Schlumberger has three types of stock-based compensation programs: (i) stock options, (ii) a restricted stock, restricted stock unit and performance share unit program (collectively referred to as “restricted stock”) and (iii) a discounted stock purchase plan (DSPP).



## Stock Options

Key employees are granted stock options under Schlumberger stock option plans. For all stock options granted, the exercise price equals the average of the high and low sales prices of Schlumberger stock on the date of grant; the maximum term is ten years, and the options generally vest in increments over five years.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions and resulting weighted-average fair value per share:

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Dividend yield</td><td>2.7%</td><td>2.3%</td><td>1.6%</td></tr><tr><td>Expected volatility</td><td>30%</td><td>36%</td><td>37%</td></tr><tr><td>Risk-free interest rate</td><td>1.7%</td><td>1.7%</td><td>2.2%</td></tr><tr><td>Expected option life in years</td><td>7.0</td><td>7.0</td><td>7.0</td></tr><tr><td>Weighted-average fair value per share</td><td>$ 17.45</td><td>$ 25.96</td><td>$ 34.20</td></tr></table>

## Restricted Stock

Schlumberger grants performance share units to certain executives. The number of shares earned is determined at the end of each performance period, which is generally three years, based on Schlumberger’s achievement of certain predefined targets as defined in the underlying performance share unit agreement. In the event Schlumberger exceeds the predefined target, shares for up to the maximum of 250% of the target award may be granted. In the event Schlumberger falls below the predefined target, a reduced number of shares may be granted. If Schlumberger falls below the threshold award performance level, no shares will be granted. As of December 31, 2016, 1.0 million performance share units were outstanding based on the achievement of 100% of target.

All other restricted stock awards generally vest at the end of three years.

Restricted stock awards do not pay dividends or have voting rights prior to vesting. Accordingly, the fair value of a restricted stock award is the quoted market price of Schlumberger’s stock on the date of grant less the present value of the expected dividends not received prior to vesting.

## Discounted Stock Purchase Plan

Under the terms of the DSPP, employees can choose to have a portion of their earnings withheld, subject to certain restrictions, to purchase Schlumberger common stock. The purchase price of the stock is 92.5% of the lower of the stock price at the beginning or end of the plan period at six-month intervals.

The fair value of the employees’ purchase rights under the DSPP was estimated using the Black-Scholes model with the following assumptions and resulting weighted-average fair value per share:

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Dividend yield</td><td>2.7%</td><td>2.3%</td><td>1.6%</td></tr><tr><td>Expected volatility</td><td>25%</td><td>27%</td><td>19%</td></tr><tr><td>Risk-free interest rate</td><td>0.5%</td><td>0.2%</td><td>0.1%</td></tr><tr><td>Weighted-average fair value per share</td><td>10.37</td><td>12.45</td><td>12.67</td></tr></table>



## Total Stock-based Compensation Expense

The following summarizes stock-based compensation expense recognized in income:

(Stated in millions)

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Stock options</td><td>$ 175</td><td>$ 176</td><td>$ 177</td></tr><tr><td>Restricted stock</td><td>47</td><td>107</td><td>114</td></tr><tr><td>DSPP</td><td>45</td><td>43</td><td>38</td></tr><tr><td></td><td>$ 267</td><td>$ 326</td><td>$ 329</td></tr></table>

At December 31, 2016, there was $480 million of total unrecognized compensation cost related to nonvested stock-based compensation arrangements, of which $212 million is expected to be recognized in 2017, $157 million in 2018, $74 million in 2019, $31 million in 2020 and $6 million in 2021.

As of December 31, 2016, approximately 20 million shares of Schlumberger common stock were available for future grants under Schlumberger’s stock-based compensation programs.

## 14. Income Taxes

Schlumberger operates in more than 100 tax jurisdictions, where statutory tax rates generally vary from 0% to 40%.

Income (loss) from continuing operations before taxes subject to United States and non-United States income taxes were as follows:

(Stated in millions)

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>United States</td><td>$ (3,103)</td><td>$ (691)</td><td>$ 1,990</td></tr><tr><td>Outside United States</td><td>1,198</td><td>3,572</td><td>5,649</td></tr><tr><td></td><td>$ (1,905)</td><td>$ 2,881</td><td>$ 7,639</td></tr></table>

Schlumberger recorded pretax charges of $3.820 billion in 2016 ($1.848 billion in the US and $1.972 billion outside of the US); $2.575 billion in 2015 ($883 million in the US and $1.692 billion outside the US); and $1.773 billion in 2014 ($289 million in the US and $1.484 billion outside the US). These charges and credits are included in the table above and are more fully described in Note 3 – Charges and Credits.

The components of net deferred tax assets (liabilities) were as follows:

(Stated in millions)

<table><tr><td></td><td>2016</td><td>2015</td></tr><tr><td>Postretirement benefits</td><td>$ 253</td><td>$ 266</td></tr><tr><td>Intangible assets</td><td>(2,869)</td><td>(1,418)</td></tr><tr><td>Investments in non-US subsidiaries</td><td>(271)</td><td>(152)</td></tr><tr><td>Fixed assets, net</td><td>(79)</td><td>(176)</td></tr><tr><td>Inventories</td><td>248</td><td>159</td></tr><tr><td>Other, net</td><td>838</td><td>454</td></tr><tr><td></td><td>$ (1,880)</td><td>$ (867)</td></tr></table>



The above deferred tax balances at December 31, 2016 and 2015 were net of valuation allowances relating to net operating losses in certain countries of $186 million and $162 million, respectively.

Schlumberger generally does not provide for taxes relating to undistributed earnings because such earnings would not be taxable when remitted or they are considered to be indefinitely reinvested. In connection with Schlumberger’s 2016 acquisition of Cameron, certain non-US subsidiaries of Cameron are now either wholly or partially owned by a US subsidiary of Schlumberger. Undistributed earnings of these non-US subsidiaries that are indefinitely invested outside the US are approximately $3 billion. Such earnings would be subject to US taxes if they were to be repatriated to the US. However, determination of the unrecognized deferred tax liability that would be incurred if such amounts were repatriated to the US is not practicable. In addition, any taxes that would be incurred if the undistributed earnings of other Schlumberger subsidiaries were distributed to their ultimate parent company would not be material.

The components of Taxes on income (loss) were as follows:

<table><tr><td rowspan="2"></td><td colspan="4">(Stated in millions)</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Current:</td><td></td><td></td><td></td><td></td></tr><tr><td>United States-Federal</td><td>$ (511)</td><td>$ 90</td><td>$ 718</td><td></td></tr><tr><td>United States-State</td><td>(36)</td><td>12</td><td>51</td><td></td></tr><tr><td>Outside United States</td><td>648</td><td>1,085</td><td>1,380</td><td></td></tr><tr><td></td><td>101</td><td>1,187</td><td>2,149</td><td></td></tr><tr><td>Deferred:</td><td></td><td></td><td></td><td></td></tr><tr><td>United States-Federal</td><td>$ (352)</td><td>$ (356)</td><td>$ (194)</td><td></td></tr><tr><td>United States-State</td><td>(13)</td><td>(19)</td><td>(9)</td><td></td></tr><tr><td>Outside United States</td><td>(51)</td><td>(52)</td><td>(12)</td><td></td></tr><tr><td>Valuation allowance</td><td>37</td><td>(14)</td><td>(6)</td><td></td></tr><tr><td></td><td>(379)</td><td>(441)</td><td>(221)</td><td></td></tr><tr><td></td><td>$ (278)</td><td>$ 746</td><td>$ 1,928</td><td></td></tr></table>

A reconciliation of the United States statutory federal tax rate (35%) to the consolidated effective tax rate follows:

A number of the jurisdictions in which Schlumberger operates have tax laws that are not fully defined and are evolving. Schlumberger’s tax filings are subject to regular audit by the tax authorities. These audits may result in assessments for additional taxes that are resolved with the tax authorities or, potentially, through the courts. Tax liabilities are recorded based on estimates of additional taxes that will be due upon the conclusion of these audits. Due to the uncertain and complex application of tax regulations, the ultimate resolution of audits may result in liabilities which could be materially different from these estimates.



A reconciliation of the beginning and ending amount of liabilities associated with uncertain tax positions for the years ended December 31, 2016, 2015 and 2014 is as follows:

(Stated in millions)

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Balance at beginning of year</td><td>$ 1,285</td><td>$ 1,402</td><td>$ 1,452</td></tr><tr><td>Additions based on tax positions related to the current year</td><td>70</td><td>140</td><td>154</td></tr><tr><td>Additions for tax positions of prior years</td><td>119</td><td>136</td><td>96</td></tr><tr><td>Additions related to acquisitions</td><td>127</td><td>5</td><td>43</td></tr><tr><td>Impact of changes in exchange rates</td><td>(25)</td><td>(78)</td><td>(62)</td></tr><tr><td>Settlements with tax authorities</td><td>(45)</td><td>(99)</td><td>(27)</td></tr><tr><td>Reductions for tax positions of prior years</td><td>(85)</td><td>(203)</td><td>(212)</td></tr><tr><td>Reductions due to the lapse of the applicable statute of limitations</td><td>(27)</td><td>(18)</td><td>(42)</td></tr><tr><td>Balance at end of year</td><td>$ 1,419</td><td>$ 1,285</td><td>$ 1,402</td></tr></table>

The amounts above exclude accrued interest and penalties of $178 million, $176 million and $243 million at December 31, 2016, 2015 and 2014, respectively. Schlumberger classifies interest and penalties relating to uncertain tax positions within Taxes on income (loss) in the Consolidated Statement of Income.

The following table summarizes the tax years that are either currently under audit or remain open and subject to examination by the tax authorities in the most significant jurisdictions in which Schlumberger operates:

<table><tr><td>Brazil</td><td>2011 - 2016</td></tr><tr><td>Canada</td><td>2009 - 2016</td></tr><tr><td>Ecuador</td><td>2013 - 2016</td></tr><tr><td>Mexico</td><td>2010 - 2016</td></tr><tr><td>Norway</td><td>2013 - 2016</td></tr><tr><td>Russia</td><td>2013 - 2016</td></tr><tr><td>Saudi Arabia</td><td>2004 - 2016</td></tr><tr><td>United Kingdom</td><td>2014 - 2016</td></tr><tr><td>United States</td><td>2014 - 2016</td></tr></table>

In certain of the jurisdictions noted above, Schlumberger operates through more than one legal entity, each of which may have different open years subject to examination. The table above presents the open years subject to examination for the most material of the legal entities in each jurisdiction. Additionally, it is important to note that tax years are technically not closed until the statute of limitations in each jurisdiction expires. In the jurisdictions noted above, the statute of limitations can extend beyond the open years subject to examination.



## 15. Leases and Lease Commitments

Total rental expense was $1.2 billion in 2016, $1.6 billion in 2015, and $2.1 billion in 2014.

Future minimum rental commitments under noncancelable operating leases for each of the next five years are as follows:

<table><tr><td rowspan="2"></td><td colspan="2">(Stated in millions)</td></tr><tr><td>$</td><td>292</td></tr><tr><td>2017</td><td>$</td><td>220</td></tr><tr><td>2018</td><td></td><td>195</td></tr><tr><td>2019</td><td></td><td>167</td></tr><tr><td>2020</td><td></td><td>132</td></tr><tr><td>2021</td><td></td><td>471</td></tr><tr><td>Thereafter</td><td></td><td>1,477</td></tr></table>

## 16. Contingencies

Schlumberger and its subsidiaries are 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.

## 17. Segment Information

Schlumberger’s segments are as follows:

- Reservoir Characterization Group – Consists of the principal Technologies involved in finding and defining hydrocarbon resources. These include WesternGeco, Wireline, Testing & Process, Software Integrated Solutions and Integrated Services Management.

- Drilling Group – Consists of the principal Technologies involved in the drilling and positioning of oil and gas wells. These include Bits & Drilling Tools, M-I SWACO, Drilling & Measurements, Land Rigs and Integrated Drilling Services.

## 18. Pension and Other Benefit Plans

## Pension Plans

Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired prior to October 1, 2004. The benefits are based on years of service and compensation, on a career-average pay basis.

In addition to the US defined benefit pension plans, Schlumberger sponsors several other international defined benefit pension plans. The most significant of these international plans are the International Staff Pension Plan and the UK pension plan (collectively, the “International plans”). The International Staff Pension Plan covers certain international employees hired prior to July 1, 2014 and is based on years of service and compensation on a career-average pay basis. The UK plan covers employees hired prior to April 1, 1999, and is based on years of service and compensation, on a final salary basis.

The weighted-average assumed discount rate, compensation increases and the expected long-term rate of return on plan assets used to determine the net pension cost for the US and International plans were as follows:

<table><tr><td rowspan="2"></td><td colspan="3">US</td><td colspan="3">International</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Discount rate</td><td>4.50%</td><td>4.15%</td><td>4.85%</td><td>4.36%</td><td>4.07%</td><td>4.76%</td></tr><tr><td>Compensation increases</td><td>4.00%</td><td>4.00%</td><td>4.00%</td><td>4.80%</td><td>4.79%</td><td>4.80%</td></tr><tr><td>Return on plan assets</td><td>7.25%</td><td>7.25%</td><td>7.25%</td><td>7.40%</td><td>7.40%</td><td>7.50%</td></tr></table>

The unfunded liability represents the difference between the plan assets and the projected benefit obligation (PBO). The PBO represents the actuarial present value of benefits based on employee service and compensation and includes an assumption about future compensation levels. The accumulated benefit obligation represents the actuarial present value of benefits based on employee service and compensation, but does not include an assumption about future compensation levels.



The weighted-average allocation of plan assets and the target allocations by asset category are as follows:

<table><tr><td rowspan="2"></td><td colspan="3">US</td><td colspan="3">International</td></tr><tr><td>Target</td><td>2016</td><td>2015</td><td>Target</td><td>2016</td><td>2015</td></tr><tr><td>Equity securities</td><td>37 - 56%</td><td>52%</td><td>52%</td><td>45 - 71%</td><td>64%</td><td>64%</td></tr><tr><td>Debt securities</td><td>35 - 62</td><td>37</td><td>36</td><td>20 - 35</td><td>25</td><td>27</td></tr><tr><td>Cash and cash equivalents</td><td>0 - 3</td><td>2</td><td>2</td><td>0 - 5</td><td>2</td><td>2</td></tr><tr><td>Alternative investments</td><td>0 - 10</td><td>9</td><td>10</td><td>0 - 25</td><td>9</td><td>7</td></tr><tr><td></td><td>100%</td><td>100%</td><td>100%</td><td>100%</td><td>100%</td><td>100</td></tr></table>

Asset performance is monitored frequently with an overall expectation that plan assets will meet or exceed the weighted index of its target asset allocation and component benchmark over rolling five-year periods.

The expected rate of return on assets assumptions reflect the long-term average rate of earnings expected on funds invested or to be invested. The assumptions have been determined based on expectations regarding future rates of return for the portfolio considering the asset allocation and related historical rates of return. The appropriateness of the assumptions is reviewed annually.

The fair value of Schlumberger’s pension plan assets at December 31, 2016 and 2015, by asset category, is presented below and was determined based on valuation techniques categorized as follows:

• Level One: The use of quoted prices in active markets for identical instruments.

- Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data.

- Level Three: The use of significant unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing.

(a) US equities include companies that are well-diversified by industry sector and equity style (i.e., growth and value strategies). Active and passive management strategies are employed. Investments are primarily in large capitalization stocks and, to a lesser extent, mid- and small-cap stocks.

(b) International equities are invested in companies that are traded on exchanges outside the US and are well-diversified by industry sector, country and equity style. Active and passive strategies are employed. The vast majority of the investments are made in companies in developed markets with a small percentage in emerging markets.

(c) Corporate bonds consist primarily of investment grade bonds from diversified industries.

(d) Government and government-related debt securities are comprised primarily of inflation-protected US treasuries and, to a lesser extent, other government-related securities.

(e) Collateralized mortgage obligations and mortgage backed-securities are debt obligations that represent claims to the cash flows from pools of mortgage loans, which are purchased from banks, mortgage companies, and other originators and then assembled into pools by governmental, quasi-governmental and private entities.

(f) Private equity includes investments in several fund of funds limited partnerships.

(g) Real estate primarily includes investments in real estate limited partnerships, concentrated in commercial real estate.

Schlumberger’s funding policy is to annually contribute amounts that are based upon a number of factors including the actuarial accrued liability, amounts that are deductible for income tax purposes, legal funding requirements and available cash flow. Schlumberger expects to contribute approximately $200 million to its postretirement benefit plans in 2017, subject to market and business conditions.



## Postretirement Benefits Other Than Pensions

Schlumberger provides certain healthcare benefits to certain former US employees who have retired. Effective April 1, 2015, Schlumberger changed the way it provides healthcare coverage to certain retirees who are age 65 and over. Under the amended plan, these retirees transferred to individual coverage under the Medicare Exchange. Schlumberger subsidizes the cost of the program by providing these retirees with a Health Reimbursement Account. The annual subsidy may be increased based on medical cost inflation, but it will not be increased by more than 5% in any given year.

The actuarial assumptions used to determine the accumulated postretirement benefit obligation and net periodic benefit cost for the US postretirement medical plan were as follows:

<table><tr><td rowspan="2"></td><td colspan="2">Benefit Obligations At December 31,</td><td colspan="3">Net Periodic Benefit Cost for the Year</td></tr><tr><td>2016</td><td>2015</td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Discount rate</td><td>4.20%</td><td>4.50%</td><td>4.50%</td><td>4.15%</td><td>4.85%</td></tr><tr><td>Return on plan assets</td><td>-</td><td>-</td><td>7.00%</td><td>7.00%</td><td>7.00%</td></tr><tr><td>Current medical cost trend rate</td><td>7.25%</td><td>7.50%</td><td>7.50%</td><td>7.00%</td><td>7.25%</td></tr><tr><td>Ultimate medical cost trend rate</td><td>5.00%</td><td>5.00%</td><td>5.00%</td><td>5.00%</td><td>(5.00%)</td></tr><tr><td>Year that the rate reaches the ultimate trend rate</td><td>2026</td><td>2023</td><td>2026</td><td>2023</td><td>2023</td></tr></table>

The net periodic benefit cost (credit) for the US postretirement medical plan included the following components:

<table><tr><td></td><td colspan="4">(Stated in millions)</td></tr><tr><td></td><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Service cost</td><td>30</td><td>42</td><td>43</td><td></td></tr><tr><td>Interest cost</td><td>47</td><td>48</td><td>60</td><td></td></tr><tr><td>Expected return on plan assets</td><td>(57)</td><td>(52)</td><td>(45)</td><td></td></tr><tr><td>Amortization of prior service credit</td><td>(32)</td><td>(32)</td><td>(4)</td><td></td></tr><tr><td>Amortization of net loss</td><td>-</td><td>13</td><td>1</td><td></td></tr><tr><td></td><td>(12)</td><td>19</td><td>55</td><td></td></tr></table>



The changes in the accumulated postretirement benefit obligation, plan assets and funded status were as follows:

<table><tr><td rowspan="2"></td><td colspan="2">(Stated in millions)</td></tr><tr><td>2016</td><td>2015</td></tr><tr><td>Change in Projected Benefit Obligations</td><td></td><td></td></tr><tr><td>Benefit obligation at beginning of year</td><td>$ 1,103</td><td>$ 1,221</td></tr><tr><td>Service cost</td><td>30</td><td>42</td></tr><tr><td>Interest cost</td><td>47</td><td>48</td></tr><tr><td>Contribution by plan participants</td><td>8</td><td>7</td></tr><tr><td>Actuarial gains</td><td>(32)</td><td>(168)</td></tr><tr><td>Benefits paid</td><td>(48)</td><td>(47)</td></tr><tr><td>Benefit obligation at end of year</td><td>$ 1,108</td><td>$ 1,103</td></tr><tr><td>Change in Plan Assets</td><td></td><td></td></tr><tr><td>Plan assets at fair value at beginning of year</td><td>$ 884</td><td>$ 854</td></tr><tr><td>Actual return on plan assets</td><td>68</td><td>4</td></tr><tr><td>Company contributions</td><td>40</td><td>66</td></tr><tr><td>Contributions by plan participants</td><td>8</td><td>7</td></tr><tr><td>Benefits paid</td><td>(48)</td><td>(47)</td></tr><tr><td>Plan assets at fair value at end of year</td><td>$ 952</td><td>$ 884</td></tr><tr><td>Unfunded Liability</td><td>$ (156)</td><td>$ (219)</td></tr><tr><td>Amounts Recognized in Accumulated Other Comprehensive Loss</td><td></td><td></td></tr><tr><td>Actuarial losses</td><td>$ 62</td><td>$ 106</td></tr><tr><td>Prior service credit</td><td>(243)</td><td>(275)</td></tr><tr><td></td><td>$ (181)</td><td>$ (169)</td></tr></table>

The unfunded liability is included in Postretirement Benefits in the Consolidated Balance Sheet.

The assets of the US postretirement medical plan are invested 63% in equity securities and 37% in debt securities at December 31, 2016. The fair value of these assets was primarily determined based on Level Two valuation techniques.

Assumed health care cost trend rates have a significant effect on the amounts reported for the US postretirement medical plan. A one percentage point change in assumed health care cost trend rates would have the following effects:

<table><tr><td rowspan="2"></td><td colspan="3">(Stated in millions)</td></tr><tr><td>One Percentage Point Increase</td><td>One Percentage Point Decrease</td><td></td></tr><tr><td>Effect on total service and interest cost components</td><td>$ 3</td><td>$ (3)</td><td></td></tr><tr><td>Effect on accumulated postretirement benefit obligation</td><td>$ 34</td><td>$ (30)</td><td></td></tr></table>

Included in Accumulated other comprehensive loss at December 31, 2016 are non-cash pretax charges which have not yet been recognized in net periodic benefit cost. The estimated portion of each component of Accumulated other comprehensive loss which is expected to be recognized as a component of net periodic benefit cost during the year ending December 31, 2017 is as follows:

In addition to providing defined pension benefits and a postretirement medical plan, Schlumberger and its subsidiaries have other deferred benefit programs, primarily profit sharing and defined contribution pension plans. Expenses for these programs were $445 million, $565 million and $749 million in 2016, 2015 and 2014, respectively.

## 20. Discontinued Operations

During 2013, Schlumberger completed the wind down of its operations in Iran and, therefore, classified the historical results of this business as a discontinued operation.

In 2009, the US Department of Justice began an investigation into past violations of US sanctions regarding Schlumberger’s historical operations in Iran and Sudan that occurred between 2004 and 2010. During the second quarter of 2014, Schlumberger increased its accrual for this contingency and recorded a $205 million charge, which was reflected within Loss from discontinued operations in the Consolidated Statement of Income.

During 2015, Schlumberger resolved this investigation and a non-US subsidiary of Schlumberger pleaded guilty to one criminal count of conspiracy to violate the International Emergency Economic Powers Act. Under the terms of the plea agreement, Schlumberger paid approximately $233 million in fines, penalties and assessments during the second quarter of 2015, which had been previously accrued. This payment is reflected within Cash flows used in discontinued operations – operating activities in Schlumberger’s Consolidated Statement of Cash Flows.



## Management’s Report on Internal Control Over Financial Reporting

Schlumberger management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a – 15(f) of the Securities Exchange Act of 1934, as amended. Schlumberger’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Schlumberger management assessed the effectiveness of its internal control over financial reporting as of December 31, 2016. In making this assessment, it used the criteria set forth in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework. Based on this assessment Schlumberger’s management has concluded that, as of December 31, 2016, its internal control over financial reporting is effective based on those criteria.

The effectiveness of Schlumberger’s internal control over financial reporting as of December 31, 2016 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.



## Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Schlumberger Limited

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of comprehensive income, of stockholders' equity and of cash flows present fairly, in all material respects, the financial position of Schlumberger Limited and its subsidiaries at December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

## Item 9A. 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 so 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 has been no change in Schlumberger’s internal control over financial reporting that occurred during the fourth quarter of 2016 that has materially affected, or is reasonably likely to materially affect, Schlumberger’s internal control over financial reporting.

## Item 9B. Other Information.

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

Schlumberger’s residual transactions or dealings with the government of Iran during 2016 consisted of payments of taxes and other typical governmental charges. Certain non-U.S. subsidiaries maintained 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-U.S. subsidiaries of Schlumberger for prior services rendered in Iran and for the maintenance of such amounts previously received. One non-U.S. subsidiary also maintains an account at Tejarat for payment of local expenses such as taxes and utilities. Schlumberger anticipates that it will discontinue its dealings with Saderat and Tejarat following the receipt of all amounts owed 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. The MOU does not involve the provision of services.
