PART I

ITEM 1. BUSINESS

General

Core Laboratories N.V. is a Netherlands limited liability company. We were established in 1936 and are one of the world's leading providers of proprietary and patented reservoir description, production enhancement and reservoir management services to the oil and gas industry. These products and services are directed toward enabling our clients to improve reservoir performance and increase oil and gas recovery from their producing fields. We have over 70 offices in more than 50 countries and have approximately 4,900 employees.

References to "Core Lab", the "Company", "we", "our", and similar phrases are used throughout this Annual Report on Form 10-K (this "Form 10-K") and relate collectively to Core Laboratories N.V. and its consolidated affiliates.

Business Strategy

Our business strategy is to provide advanced technologies that improve reservoir performance by (i) continuing the development of proprietary technologies through client-driven research and development, (ii) expanding the services and products offered throughout our global network of offices and (iii) acquiring complementary technologies that add key technologies or market presence and enhance existing products and services.

Development of New Technologies, Services and Products

We conduct research and development to meet the needs of our clients who are continually seeking new services and technologies to lower their costs of finding, developing and producing oil and gas. While the aggregate number of wells being drilled per year has fluctuated relative to market conditions, oil and gas producers have, on a proportional basis, increased expenditures on technology services to improve their understanding of the reservoir and increase production of oil and gas from their producing fields. We intend to continue concentrating our efforts on services and technologies that improve reservoir performance and increase oil and gas recovery.

International Expansion of Services and Products

Another component of our business strategy is to broaden the spectrum of services and products offered to our clients on a global basis. We intend to continue using our worldwide network of offices to offer many of our services and products that have been developed internally or obtained through acquisitions. This allows us to enhance our revenues through efficient utilization of our worldwide network.

Acquisitions

We continually review potential acquisitions to add key services and technologies, enhance market presence or complement existing businesses.

More information relating to our acquisitions is included in Note 3 of the Notes to Consolidated Financial Statements in this Form 10-K ("Notes to Consolidated Financial Statements").

Operations

We derive our revenues from services and product sales to clients primarily in the oil and gas industry.

Our reservoir optimization services and technologies are interrelated and are organized into three complementary segments. Disclosure relating to the operations and financial information of these business segments is included in Note 15 of the Notes to Consolidated Financial Statements.

Return to table of contents

-	Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.

-	Production Enhancement: Includes products and services relating to reservoir well completions, perforations, stimulations and production. We provide integrated services to evaluate the effectiveness of well completions and to develop solutions aimed at increasing the effectiveness of enhanced oil recovery projects.

-	Reservoir Management: Combines and integrates information from reservoir description and production enhancement services to increase production and improve recovery of oil and gas from our clients' reservoirs.

We offer our services worldwide through our global network of offices. Services accounted for approximately 80%, 77% and 76% of our revenues from operations for the years ended December 31, 2009, 2008 and 2007, respectively.

We manufacture products primarily in four facilities for distribution on a global basis. Product sales, generated principally in our Production Enhancement segment, accounted for approximately 20%, 23% and 24% of our revenues from operations for the years ended December 31, 2009, 2008 and 2007, respectively.

Our product sales backlog at December 31, 2009 was approximately $24.2 million compared to $21.8 million at December 31, 2008. Sources of raw materials for our products are readily available and we expect that our current sales backlog at December 31, 2009 will be completed in 2010.

Reservoir Description

Commercial oil and gas fields consist of porous and permeable reservoir rocks that contain natural gas, crude oil and water. Due to the density differences of the fluids, natural gas typically caps the field and overlies an oil layer, which overlies the water. We provide services that characterize the porous reservoir rock and all three reservoir fluids. Services relating to these fluids include determining quality and measuring quantity of the fluids and their derived products. This includes determining the value of different crude oil and natural gases by analyzing the individual components of complex hydrocarbons. These data sets are used by oil companies to determine the most efficient method by which to recover, process and refine these hydrocarbons to produce the maximum value added to crude oil and natural gas.

We analyze samples of reservoir rocks for their porosity, which determines reservoir storage capacity, and for their permeability, which defines the ability of the fluids to flow through the rock. These measurements are used to determine how much oil and gas are present in a reservoir and the rates at which the oil and gas can be produced. We also use our proprietary services and technologies to correlate the reservoir description data to wireline logs and seismic data by determining the different acoustic velocities of reservoir rocks containing water, oil and natural gas. These measurements are used in conjunction with our reservoir management services to develop programs to produce more oil and gas from the reservoir.

Production Enhancement

We produce data to describe a reservoir system that is used to enhance oil and gas production so that it may exceed the average oilfield recovery factor, which is approximately 40%. Two production enhancement methods commonly used are (i) hydraulic fracturing of the reservoir rock to improve flow and (ii) flooding a reservoir with water, carbon dioxide, nitrogen or hydrocarbon gases to force more oil and gas to the wellbore. Many oilfields today are hydraulically fractured and flooded to maximize oil and gas recovery. Our services and technologies play a key role in the success of both methods.

The hydraulic fracturing of a producing formation is achieved by pumping a proppant material in a gel slurry into the reservoir zone at extremely high pressures. This forces fractures to open in the rock and "props" or holds the fractures open so that reservoir fluids can flow to the production wellbore. Our data on rock type and strength are critical for determining the proper design of the hydraulic fracturing job. In addition, our testing indicates whether the gel slurry is compatible with the reservoir fluids so that damage does not occur to the porous rock network. Our proprietary and patented ZeroWash™ tracer technology is used to determine that the proppant material was properly placed in the fracture to ensure effective flow and increased recovery.

SpectraChem® is another proprietary and patented technology developed for optimizing hydraulic fracture performance. SpectraChem® is used to aid operators in determining the efficiency of the fracture fluids used. SpectraChem® tracers allow operators to evaluate the quantity of fracture fluid that returns to the wellbore during the clean-up period after a hydraulic fracturing event. This technology also allows our clients to evaluate load recovery, gas breakthrough, fluid leakoff and breaker efficiency, all of which are important factors for optimizing natural gas production after the formation is hydraulically fractured.

Return to table of contents

Core’s patented and proprietary SpectraChem® fracture diagnostic service continued to evolve with the introduction of the SpectraChem® Plus+ service in early 2009. The new SpectraChem® Plus+ service is effective in determining the effectiveness and efficiency of the hydraulic fracture stimulation of long multistage horizontal wells in gas-shale plays throughout North America. SpectraChem® Plus+ data sets are used to determine how each frac stage, which may number up to 30 per well, is flowing. Frac stages with ineffective flows may warrant further stimulation or remedial actions. In addition, SpectraChem® Plus+ data sets can be used to prove that hydraulic fracturing techniques have not invaded fresh water zones.

We conduct dynamic flow tests of the reservoir fluids through the reservoir rock, at actual reservoir pressure and temperature, to realistically simulate the actual flooding of a producing zone. We use patented technologies, such as our Saturation Monitoring by the Attenuation of X-rays (SMAX™), to help design the enhanced recovery project. After a field flood is initiated, we are often involved in monitoring the progress of the flood to ensure the maximum amount of incremental production is being achieved through the use of our SpectraFloodTM technology, which we developed to optimize sweep efficiency during field floods.

Our unique completion monitoring system, Completion Profiler™, helps to determine flow rates from reservoir zones after they have been hydraulically fractured. This provides our clients with a baseline of early production information and can be compared to subsequent production logs later in the life of the well to see if and where hydrocarbon production varies.

Our PackScan™ patented technology, which is used as a tool to evaluate gravel pack effectiveness in an unconsolidated reservoir, has contributed to our revenue growth. PackScan™ measures the density changes in the area around the tool and is designed to observe the changes within the wellbore to verify the completeness of the gravel pack protection of the wellbore without any additional rig time.

In addition to our many patented reservoir analysis technologies, we have established ourselves as a global leader in the manufacture and distribution of high-performance perforating products. Our unique understanding of complex reservoirs supports our ability to supply perforating systems engineered to maximize well productivity by reducing, eliminating and overcoming formation damage caused during the completion of oil and gas wells. Our "systems" approach to the perforating of an oil or gas well has resulted in numerous patented products. Our HERO™ (High Efficiency Reservoir Optimization) and recently introduced SuperHERO™ and SuperHERO Plus+™ perforating systems have quickly become industry leaders in enhancing reservoir performance. The SuperHERO™ and SuperHERO Plus+™ perforating systems are expected to compliment our successful HERO™ line and are designed to optimize wellbore completions and stimulation programs in gas-shale reservoirs. Evolved from our HERO™ charges, the SuperHERO™ and the SuperHERO Plus+™ charges use a proprietary and patented design of powdered metal liners and explosives technology that results in a deeper and cleaner perforating tunnel into the gas-shale reservoir. This allows greater flow of hydrocarbons to the wellbore and helps to maximize hydrocarbon recovery from the reservoir. Moreover, the deeper, near debris-free perforations enable lower fracture initiation pressures, reducing the amount of pressure-pumping horsepower required and its associated cost. SuperHERO™ and SuperHERO Plus+™ charges can eliminate the ineffective perforations that would otherwise limit daily natural gas production and hinder the optimal fracture stimulation programs needed for prolific production from the Marcellus, Barnett, Fayetteville, Haynesville and similar gas-shale formations. Our manufacturing operations in the United States and Canada continue to meet the global demand for our perforating systems through facility expansion in addition to gains in efficiency and productivity.

We have experienced technical services personnel to support clients through our global network of offices for the everyday use of our perforating systems and the rapid introduction of new products. Our personnel are capable of providing client training and on-site service in the completion of oil and gas wells. Our patented X-SPAN™ and GTX-SPAN™ casing patches are supported by our technical services personnel. These systems are capable of performing in high pressure gas environments and are used to seal non-productive reservoir zones from the producing wellbore.

Reservoir Management

Reservoir description and production enhancement information, when applied across an entire oilfield, is used to maximize daily production and the ultimate total recovery from the reservoir. We are involved in numerous large-scale reservoir management projects, applying proprietary and state-of-the-art techniques from the earliest phases of a field development program until the last economic barrel of oil is recovered.

These projects are of increasing importance to oil companies as the incremental barrel is often the lowest cost and most profitable barrel in the reservoir. Producing incremental barrels increases our clients' cash flows which we believe will result in additional capital expenditures by our clients, and ultimately further opportunities for us. We also develop and provide industry consortium studies to provide critical reservoir information to a broad spectrum of clients in a cost effective manner such as our multi-client regional reservoir optimization projects for both North America and international studies, especially studies pertaining to unconventional natural gas reservoirs such as our ongoing gas-shale studies entitled Reservoir Characterization and Production Properties of the

Return to table of contents

Haynesville and Bossier Shales in Louisiana and Texas, Marcellus Shale Study in the Appalachian Mountains, Reservoir Characterization and Production Properties of Gas Shales and a joint industry project evaluating the petrophysical, geochemical and production characteristics of the Eagle Ford Shale in South Texas. Additional studies being performed are our long running deep water Gulf of Mexico studies, a worldwide characterization of tight-gas sands, with special emphasis in the Middle East region, deepwater studies off the coasts of West Africa and Brazil, a study on the petroleum potential of offshore Vietnam and the introduction of a Global Gas Shale Study that examines the gas shale potential in central and southern Europe, north Africa, India, China and Australia among other regions.

We sell and maintain permanent reservoir monitoring equipment installed in the reservoir for our oil and gas company clients.

Marketing and Sales

We market and sell our services and products through a combination of sales representatives, technical seminars, trade shows and print advertising. Direct sales and marketing are carried out by our sales force, technical experts and operating managers, as well as by sales representatives and distributors in various markets where we do not have offices. Our Business Development group manages a Large Account Management Program to better serve our largest and most active clients by meeting with key personnel within their organization to ensure the quality of our products and services are meeting their expectations and we are addressing any issues or needs in a timely manner.

Research and Development

The market for our products and services is characterized by changing technology and frequent product introduction. As a result, our success is dependent upon our ability to develop or acquire new products and services on a cost-effective basis and to introduce them into the marketplace in a timely manner. Many of our acquisitions have allowed us to obtain the benefits of the acquired company's research and development projects without the significant costs that would have been incurred if we had attempted to develop the products and services ourselves. We incur costs as part of internal research and development and these costs are charged to expense as incurred. We intend to continue committing financial resources and effort to the development and acquisition of new products and services. Over the years, we have made a number of technological advances, including the development of key technologies utilized in our operations. Substantially all of the new technologies have resulted from requests and guidance from our clients, particularly major oil companies.

Patents and Trademarks

We believe our patents, trademarks and other intellectual property rights are an important factor in maintaining our technological advantage, although no one patent is considered essential to our success. Typically, we will seek to protect our intellectual technology in all jurisdictions where we believe the cost of such protection is warranted. While we have patented some of our key technologies, we do not patent all of our proprietary technology even where regarded as patentable. In addition to patents, in many instances we protect our trade secrets through confidentiality agreements with our employees and our clients.

International Operations

We operate facilities in more than 50 countries. Our non-U.S. operations accounted for approximately 52%, 50% and 51% of our revenues from operations during the years ended December 31, 2009, 2008 and 2007, respectively. Not included in the foregoing percentages are significant levels of our revenues recorded in the U.S. that are sourced from projects on foreign oilfields.

While we are subject to fluctuations and changes in currency exchange rates relating to our international operations, we attempt to limit our exposure to foreign currency fluctuations by limiting the amount in which our foreign contracts are denominated in a currency other than the U.S. dollar to an amount generally equal to the expenses expected to be incurred in such foreign currency. However, the ultimate decision as to the proportion of the foreign currency component within a contract usually resides with our clients. Consequently, we are not able to always eliminate our foreign currency exposure. We have not historically engaged in and are not currently engaged in any significant hedging or currency trading transactions designed to compensate for adverse currency fluctuations. The following graphs summarize our reported revenues by geographic region (in contrast to the location of the reservoirs) for the years ended December 31, 2009, 2008 and 2007:

Geographic Breakdown of Revenues

Environmental Regulation

We are subject to stringent governmental laws and regulations pertaining to protection of the environment and the manner in which chemicals and gases used in our analytical and manufacturing processes are handled and generated wastes are disposed. Consistent with our quality assurance and control principles, we have established proactive environmental policies for the management of these chemicals and gases as well as the handling and recycling or disposal of wastes resulting from our operations. Compliance with these laws and regulations may require the acquisition of permits for regulated activities, capital expenditures to limit or prevent emissions and discharges, and special precautions for disposal of certain wastes. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations, and even the issuance of injunctive relief. The trend in environmental regulation has been to place more restrictions and limitations on activities that may affect the environment and thus any changes in environmental laws and regulations that result in more stringent and costly waste handling, storage, transport, disposal or cleanup requirements could have a material adverse effect on our operations and financial position. For instance, the adoption of laws or implementing regulations with regard to climate change that have the effect of lowering the demand for carbon-based fuels could have a material adverse effect on our business.

Our analytical and manufacturing processes involve the handling and use of numerous chemicals and gases as well as the generation of wastes. Spills or releases of these chemicals, gases, and wastes at our facilities or at offsite locations where they are transported for recycling or disposal could subject us to environmental liability, which may be strict, joint and several, for the costs of cleaning up chemicals and wastes released into the environment and for damages to natural resources, and it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by such spills or releases. As a result of such actions, we could be required to remove previously disposed wastes, remediate environmental contamination, and undertake measures to prevent future contamination. While we believe that we are in substantial compliance with current applicable environmental laws and regulations and that continued compliance with existing requirements will not have a material adverse impact on us, we cannot give any assurance that this trend will continue in the future.

Competition

The businesses in which we engage are competitive. Some of our competitors are divisions or subsidiaries of companies that are larger and have greater financial and other resources than we have. While no one company competes with us in all of our product and service lines, we face competition in these lines, primarily from independent regional companies and internal divisions of major integrated oil and gas companies. We compete in different product and service lines to various degrees on the basis of price, technical performance, availability, quality and technical support. Our ability to compete successfully depends on elements both within and outside of our control, including successful and timely development of new products and services, performance and quality, client service, pricing, industry trends and general economic trends.

Reliance on the Oil and Gas Industry

Our business and operations are substantially dependent upon the condition of the global oil and gas industry. Future downturns in the oil and gas industry, or in the oilfield services business, may have a material adverse effect on our financial position, results of operations or cash flows.

Return to table of contents

The oil and gas industry is highly cyclical and has been subject to significant economic downturns at various times as a result of numerous factors affecting the supply of and demand for oil and natural gas, including the level of capital expenditures of the oil and gas industry; the level of drilling activity; the level of production activity; market prices of oil and gas; economic conditions existing in the world; interest rates and the cost of capital; environmental regulations; tax policies; political requirements of national governments; coordination by the Organization of Petroleum Exporting Countries ("OPEC"); cost of producing oil and natural gas; and technological advances.

Employees

As of December 31, 2009, we had approximately 4,900 employees. We do not have any material collective bargaining agreements and consider relations with our employees to be good.

ITEM 1A. RISK FACTORS

Our forward-looking statements are based on assumptions that we believe to be reasonable but that may not prove to be accurate. All of our forward-looking information is, therefore, subject to risks and uncertainties that could cause actual results to differ materially from the results expected. Although it is not possible to identify all factors, these risks and uncertainties include the risk factors discussed below.

Future downturns in the oil and gas industry, or in the oilfield services business, may have a material adverse effect on our financial condition or results of operations.

The oil and gas industry is highly cyclical and demand for the majority of our oilfield products and services is substantially dependent on the level of expenditures by the oil and gas industry for the exploration, development and production of crude oil and natural gas reserves, which are sensitive to oil and natural gas prices and generally dependent on the industry's view of future oil and gas prices. There are numerous factors affecting the supply of and demand for our products and services, which include, but are not limited to:

-	general and economic business conditions;

-	market prices of oil and gas and expectations about future prices;

-	cost of producing oil and natural gas;

-	the level of drilling and production activity;

-	mergers, consolidations and downsizing among our clients;

-	coordination by OPEC;

-	the impact of commodity prices on the expenditure levels of our clients;

-	financial condition of our client base and their ability to fund capital expenditures;

-	the physical effects of climatic change, including adverse weather conditions;

-	civil unrest in oil producing countries;

-	level of consumption of oil, gas and petrochemicals by consumers;

-	the adoption of legal requirements relating to climate change that lower the demand for petroleum-based fuels;

-	changes in existing laws or regulations;

-	the business opportunities (or lack thereof) that may be presented to and pursued by us; and

-	availability of services and materials for our clients to grow their capital expenditures.

The oil and gas industry has historically experienced periodic downturns, which have been characterized by diminished demand for our oilfield products and services and downward pressure on the prices we charge. A significant downturn in the oil and gas industry could result in a reduction in demand for oilfield services and could adversely affect our operating results.

In the last few months of 2008, the market price of oil and natural gas decreased significantly and disruptions and instability in the global financial markets resulted in a significant reduction in the general availability of funds to companies from the equity and debt capital markets and other credit markets. During 2009, the market prices for oil and gas remained at depressed levels for most of the year when compared to average prices for 2007 and 2008 and average rig counts in North America were greatly reduced from 2008 levels. Many of our customers reduced their capital expenditure in 2009 and may continue to maintain their capital expenditures at reduced levels in 2010. This may result in less growth opportunities for our oilfield products and services and cause downward pressure on the prices we charge or the level of work that we do for our clients. A significant or prolonged reduction in demand for oilfield services could adversely affect our operating results.

Return to table of contents

We depend on the results of our international operations, which expose us to risks inherent in doing business abroad.

We conduct our business in over 50 countries; business outside of the United States accounted for approximately 52%, 50% and 51% of our revenues during the years ended December 31, 2009, 2008 and 2007, respectively. Not included in the foregoing percentages are significant levels of our revenues recorded in the U.S. that are sourced from projects on foreign oilfields. Our operations are subject to the various laws and regulations of those respective countries as well as various risks peculiar to each country, which may include, but are not limited to:

-	global economic conditions;

-	political actions and requirements of national governments including trade restrictions, embargoes, seizure, detention, nationalization and expropriations of assets;

-	interpretation of tax statutes and requirements of taxing authorities worldwide, routine examination by taxing authorities and assessment of additional taxes, penalties and/or interest;

-	civil unrest;

-	acts of terrorism;

-	fluctuations and changes in currency exchange rates;

-	the impact of inflation;

-	difficulty in repatriating foreign currency received in excess of the local currency requirements; and

-	current conditions in oil producing countries such as Venezuela, Nigeria, Iran and Iraq considering their potential impact on the world markets.

Historically, economic downturn and political events have resulted in lower demand for our products and services in certain markets. The ongoing conflict in Iraq and the potential for activity from terrorist groups that the U.S. government has cautioned against have further heightened our exposure to international risks. The global economy is highly influenced by public confidence in the geopolitical environment and the situation in the Middle East continues to be highly fluid; therefore, we expect to experience heightened international risks.

Our results of operations may be significantly affected by foreign currency exchange rate risk.

We are exposed to risks due to fluctuations in currency exchange rates. By the nature of our business, we derive a substantial amount of our revenues from our international operations, subjecting us to risks relating to fluctuations in currency exchange rates. For example, as a result of devaluation of the Venezuelan Bolivar, we recognized a foreign exchange loss of approximately $1.3 million in the fourth quarter of 2009. See Item 7A “Quantitative and Qualitative Disclosures About Market Risk – Foreign Currency Risk” for additional discussion of the Venezuela currency devaluation. Our revenues and expenses are mainly denominated in U.S. dollar ("USD"). Fluctuations in the exchange rate of the USD against such other currencies may in the future have an effect upon our results of operations.

Our results of operations may be adversely affected because our efforts to comply with U.S. laws such as the Foreign Corrupt Practices Act (the "FCPA") could restrict our ability to do business in foreign markets relative to our competitors who are not subject to U.S. law.

We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. We may be subject to competitive disadvantages to the extent that our competitors are able to secure business, licenses or other preferential treatment by making payments to government officials and others in positions of influence or using other methods that U.S. law and regulations prohibit us from using.

Return to table of contents

Because we are registered with the U.S. Securities and Exchange Commission, we are subject to the regulations imposed by the FCPA, which generally prohibits us and our intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. In particular, we may be held liable for actions taken by our strategic or local partners even though our partners are not subject to the FCPA. Any such violations could result in substantial civil and/or criminal penalties and might adversely affect our business, results of operations or financial condition. In addition, our ability to continue to work in these parts of the world discussed above could be adversely affected if we were found to have violated certain U.S. laws, including the FCPA.

If we are not able to develop or acquire new products or our products become technologically obsolete, our results of operations may be adversely affected.

The market for our products and services is characterized by changing technology and frequent product introduction. As a result, our success is dependent upon our ability to develop or acquire new products and services on a cost-effective basis and to introduce them into the marketplace in a timely manner. While we intend to continue committing substantial financial resources and effort to the development of new products and services, we may not be able to successfully differentiate our products and services from those of our competitors. Our clients may not consider our proposed products and services to be of value to them; or if the proposed products and services are of a competitive nature, our clients may not view them as superior to our competitors' products and services. In addition, we may not be able to adapt to evolving markets and technologies, develop new products, or achieve and maintain technological advantages.

If we are unable to continue developing competitive products in a timely manner in response to changes in technology, our businesses and operating results may be materially and adversely affected. In addition, continuing development of new products inherently carries the risk of inventory obsolescence with respect to our older products.

If we are unable to obtain patents, licenses and other intellectual property rights covering our products and services, our operating results may be adversely affected.

Our success depends, in part, on our ability to obtain patents, licenses and other intellectual property rights covering our products and services. To that end, we have obtained certain patents and intend to continue to seek patents on some of our inventions and services. While we have patented some of our key technologies, we do not patent all of our proprietary technology, even when regarded as patentable. The process of seeking patent protection can be long and expensive. There can be no assurance that patents will be issued from currently pending or future applications or that, if patents are issued, they will be of sufficient scope or strength to provide meaningful protection or any commercial advantage to us. In addition, effective copyright and trade secret protection may be unavailable or limited in certain countries. Litigation, which could demand significant financial and management resources, may be necessary to enforce our patents or other intellectual property rights. Also, there can be no assurance that we can obtain licenses or other rights to necessary intellectual property on acceptable terms.

There are risks relating to our acquisition strategy. If we are unable to successfully integrate and manage businesses that we have acquired and any businesses acquired in the future, our results of operations and financial condition could be adversely affected.

One of our key business strategies is to acquire technologies, operations and assets that are complementary to our existing businesses. There are financial, operational and legal risks inherent in any acquisition strategy, including:

-	increased financial leverage;

-	ability to obtain additional financing;

-	increased interest expense; and

-	difficulties involved in combining disparate company cultures and facilities.

The success of any completed acquisition will depend on our ability to integrate effectively the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier acquisitions. No assurance can be given that we will be able to continue to identify additional suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire identified targets. Our failure to achieve consolidation savings, to incorporate the acquired businesses and assets

into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our financial condition and results of operation.

We are subject to a variety of environmental laws and regulations, which may result in increased costs and significant liability to our business.

We are subject to a variety of governmental laws and regulations both in the United States and abroad relating to protection of the environment and the use and storage of chemicals and gases used in our analytical and manufacturing processes and the discharge and disposal of wastes generated by those processes. These laws and regulations may impose joint and several, strict liability and failure to comply with such laws and regulations could result in the assessment of damages, fines and penalties, the imposition of remedial or corrective action obligations or the suspension or cessation of operations. Stringent laws and regulations could require us to acquire permits or other authorizations to conduct regulated activities, install and maintain costly equipment and pollution control technologies, or to incur other significant environmental-related expenses. If we fail to control the use, or adequately restrict the discharge of, hazardous substances or wastes, we could be subject to future material liabilities including remedial obligations. In addition, public interest in the protection of the environment has increased dramatically in recent years with governmental authorities imposing more stringent and restrictive requirements. We anticipate that the trend of more expansive and stricter environmental laws and regulations will continue, the occurrence of which may require us to increase our capital expenditures or could result in increased operating expenses.

The U.S. Senate and House of Representatives are currently considering bills, entitled “Fracturing Responsibility and Awareness of Chemicals Act,” or FRAC Act, to amend the federal Safe Drinking Water Act, or the SDWA, to repeal an exemption from regulation for hydraulic fracturing. Among other things, the FRAC Act proposes to amend the definition of “underground injection” in the SDWA to encompass hydraulic fracturing activities. If enacted, such a provision could require hydraulic fracturing operations to meet permitting and financial assurance requirements, adhere to certain construction specifications, fulfill monitoring, reporting and recordkeeping obligations, and meet plugging and abandonment requirements. The FRAC Act also proposes to require the reporting and public disclosure of chemicals used in the fracturing process, which could make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific chemicals used in the fracturing process could adversely affect groundwater. Although the legislation is still being developed, if it were enacted it could have an adverse effect on our operations.

We may be unable to attract and retain skilled and technically knowledgeable employees, which could adversely affect our business.

Our success depends upon attracting and retaining highly skilled professionals and other technical personnel. A number of our employees are highly skilled engineers, geologists and highly trained technicians, and our failure to continue to attract and retain such individuals could adversely affect our ability to compete in the oilfield services industry. We may confront significant and potentially adverse competition for these skilled and technically knowledgeable personnel, particularly during periods of increased demand for oil and gas. Additionally, at times there may be a shortage of skilled and technical personnel available in the market, potentially compounding the difficulty of attracting and retaining these employees. As a result, our business, results of operations and financial condition may be materially adversely affected.

We require a significant amount of cash to service our indebtedness, and our ability to generate cash will depend on many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness, and to fund planned capital expenditures depends, in part, on our ability to generate cash in the future. This ability is, to a certain extent, subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

No assurance can be given that we will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to service and repay our indebtedness or to fund our other liquidity needs. If we are unable to satisfy our debt obligations, we may have to undertake alternative financing plans, such as refinancing or restructuring our indebtedness, selling assets, reducing or delaying capital investments or seeking to raise additional capital. We cannot assure that any refinancing or debt restructuring would be possible or, if possible, would be completed on favorable or acceptable terms, that any assets could be sold or that, if sold, the timing of the sales and the amount of proceeds realized from those sales would be favorable to us or that additional financing could be obtained on acceptable terms. Disruptions in the capital and credit markets could adversely affect our ability to refinance our indebtedness, including our ability to borrow under our existing Credit Facility. Banks that are party to our existing Credit Facility may not be able to meet their funding commitments to us if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests from us and other borrowers within a short period of time.

Because we are a Netherlands company, it may be difficult for you to sue our supervisory directors or us and it may not be possible to obtain or enforce judgments against us.

Although we are a Netherlands company, our assets are located in a variety of countries. In addition, not all members of our supervisory board of directors are residents of the same countries as other supervisory directors. As a result, it may not be possible for you to effect service of process within certain countries upon our supervisory directors, or to enforce against our supervisory directors or us judgments of courts of certain countries predicated upon civil liabilities under a country's federal securities laws. Because there is no treaty between certain countries and The Netherlands providing for the reciprocal recognition and enforcement of judgments, some countries' judgments are not automatically enforceable in The Netherlands or in the United States, where the principal market for our shares is located. In addition, there is doubt as to whether a court in one country would impose civil liability on us or on the members of our supervisory board of directors in an original action brought against us or our supervisory directors in a court of competent jurisdiction in another country and predicated solely upon the federal securities laws of that other country.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Currently, we have over 70 offices (totaling approximately 1.8 million square feet of space) in more than 50 countries. In these locations, we lease approximately 1.4 million square feet and own approximately 0.4 million square feet. We serve our worldwide clients through six Advanced Technology Centers ("ATCs") that are located in Houston, Texas; Calgary, Canada; Kuala Lumpur, Malaysia; Rotterdam, The Netherlands; Abu Dhabi, UAE; and Aberdeen, Scotland. The ATCs provide support for our more than 50 regional specialty centers located throughout the global energy producing provinces. In addition, we have significant manufacturing facilities located in Godley, Texas, and Red Deer, Alberta, Canada, which are included in our Production Enhancement business segment. Our facilities are adequate for our current operations. However, expansion into new facilities may be required to accommodate future growth.

ITEM 3. LEGAL PROCEEDINGS

From time to time, we may be subject to legal proceedings and claims that arise in the ordinary course of business.

See Part III, "Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters" for discussion of equity compensation plans.

Dividend Policy

In July 2008, Core Laboratories announced the initiation of a cash dividend program. Cash dividends of $0.10 per share were paid in August and November 2008 and in March, May, August and November of 2009. In January 2010, our Board of Supervisory Directors approved a dividend of $0.12 per share, representing a 20% increase in the quarterly dividend, to be paid in February 2010. In addition, special non-recurring cash dividends of $1.00 per share and $0.75 per share were paid in August 2008 and August 2009, respectively. The declaration and payment of future dividends, will be at the discretion of the Supervisory Board of Directors and will depend upon, among other things, future earnings, general financial condition, liquidity, capital requirements, and general business conditions.

Because we are a holding company that conducts substantially all of our operations through subsidiaries, our ability to pay cash dividends on the common shares is also dependent upon the ability of our subsidiaries to pay cash dividends or otherwise distribute or advance funds to us and on the terms and conditions of our existing and future credit arrangements. See "Liquidity and Capital Resources" included in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations."

Performance Graph

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

Core Laboratories N.V. is a Netherlands limited liability company. We were established in 1936 and are one of the world's leading providers of proprietary and patented reservoir description, production enhancement and reservoir management products and services to the oil and gas industry, primarily through customer relationships with many of the world's major, national and independent oil companies.

Our business units have been aggregated into three complementary segments:

-	Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.

-	Production Enhancement: Includes products and services relating to reservoir well completions, perforations, stimulations and production. We provide integrated services to evaluate the effectiveness of well completions and to develop solutions aimed at increasing the effectiveness of enhanced oil recovery projects.

-	Reservoir Management: Combines and integrates information from reservoir description and production enhancement services to increase production and improve recovery of oil and gas from our clients' reservoirs.

General Overview

We provide services and design and produce products which enable our clients to evaluate reservoir performance and increase oil and gas recovery from new and existing fields. These services and products are generally in higher demand when our clients are investing capital in exploration and development efforts to explore new fields or to increase productivity in existing fields. Our clients' investment in capital expenditure programs tends to correlate to oil and natural gas commodity prices. During periods of higher prices, our clients generally invest more in capital expenditures and, during periods of lower commodity prices, they tend to invest less. Accordingly, the level of capital expenditures by our clients impacts the demand for our services and products.

In 2007, prices for crude oil climbed throughout the year reaching record highs which continued to drive the increase in the oilfield service sector activity levels. Prices for crude oil continued their rapid climb through the first half of 2008 reaching an all time high before quickly declining the second half of the year to 2004 levels due to a decrease in demand driven by the economic downturn. During 2009, prices for crude remained low, but climbed through the year returning to mid-2007 levels by year-end.

Prices for natural gas continued to increase through the first half of 2008 as general oil market conditions in the United States improved along with a continued increase in global demand which contributed to increasing the price for natural gas as well as its derivative crude-oil products and petrochemical products. Later in 2008, as the downturn in the economy began, commodity prices began a downward slide due primarily from a decline in demand. Natural gas prices continued to decline during the first quarter of 2009 before showing a gradual but steady improvement through the last quarters of the year returning to a level slightly higher than at the beginning of the year as the economy began to show signs of recovery.

The following table summarizes the average worldwide and U.S. rig counts for the years ended December 31, 2009, 2008 and 2007, as well as the annual average spot price of a barrel of West Texas Intermediate crude and an MMBtu of natural gas:

Return to table of contents

For most of 2008, global demand for oil and gas and drilling activity were at the highest levels in over twenty years. In the second half of 2008, the financial market crisis and beginnings of a global economic recession led to a decrease in demand for oil and gas and oilfield activity in North America began to decline as oil and gas companies reduced their spending levels. As a result, the North American rig count began to fall dramatically in late 2008 and in 2009, the average rig count in North America was down over 40% as prices for oil and gas were also down significantly from recent years. However, oil and gas prices began to increase in the second half of 2009 and the North American Rig count began to rise slightly in the last quarter of 2009. Industry activity levels outside of North America did not experience these same reductions that North America did in the latter part of 2008, however in 2009 the international market activity also declined as the global demand for energy weakened.

In 2008, the higher industry wide activity levels resulted in increased revenues for us in 2008 across all of our business segments. Despite the significant decrease in the global demand for the energy industry’s products and services in 2009, our 2009 annual revenues only decreased by 11%. In North America, our 2009 sales revenues declined by 16%, a much lower rate than the 42% decrease in the average North American rig count from 2008 to 2009. The increase in North American activity in the fourth quarter of 2009 as well as our improved penetration of international markets throughout the year helped to mitigate the impact of lower industry-wide demand levels for some of our products and services during 2009. Additionally, our operating income was only down 10% as we were able to reduce costs and substantially maintain our overall margins. Revenues in 2009 for our Reservoir Description segment, which is not as sensitive to North America drilling activity, decreased slightly by 5% due to the downturn in the global economy; however, operating income increased due to our cost reduction efforts. Our Production Enhancement revenues and operating income for 2009 decreased primarily due to the sharp decline in the North American drilling activity; however, the segment performed strong when compared to the decrease in the average North American rig count. The results for our Reservoir Management group showed a modest decrease as our customer’s spending levels decreased in 2009, but still performed well primarily to the success of our multi-client reservoir studies.

Outlook

We continue our efforts to expand our market presence by opening facilities in strategic areas and realizing synergies within our business lines. We believe our market presence provides us a unique opportunity to service customers who have global operations in addition to the national oil companies.

We have established internal earnings targets that are based on current market conditions existing at the time our targets were established. Based on recent developments, we believe that the current level of activities, workflows, and operating margins outside North America will grow slightly and that North American activity levels will gradually increase in response to natural gas prices stabilizing. Recent natural gas production data indicates that the North American supply is now decreasing and may continue to decrease over the next several quarters. In addition, the North American rig count has recently increased slightly.

We expect to meet ongoing working capital needs, capital expenditure requirements and funding of our dividend and share repurchase programs from a combination of cash on hand, cash flow from operating activities and available borrowings under our revolving credit facility

Critical Accounting Policies and Estimates

Our financial statements are prepared in conformity with generally accepted accounting principles in the U.S. ("U.S. GAAP") and require us to make estimates and assumptions during their preparation which requires judgment. Our accounting policies and procedures are explained in Note 2 to the Notes to the Consolidated Financial Statements contained elsewhere in this Annual Report on Form 10-K. The following transaction types require significant judgment and, therefore, are considered critical accounting policies as of December 31, 2009:

Revenue Recognition

Revenues are recognized as services are completed or as product title is transferred. All advance client payments are classified as unearned revenues until services are performed or product title is transferred. We recognize revenue when we determine that the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. Revenues from long-term contracts are recorded as services are rendered in proportion to the work performed. All known or anticipated losses on contracts are provided for currently. Training and consulting service revenues are recognized as the services are performed.

Return to table of contents

Allowance for Doubtful Accounts

We perform ongoing credit evaluations of our clients and monitor collections and payments in order to maintain a provision for estimated uncollectible accounts based on our historical collection experience and our current aging of client receivables outstanding in addition to clients' representations and our understanding of the economic environment in which our clients operate. Based on our review, we establish or adjust allowances for specific customers and the accounts receivable as a whole. Our allowance for doubtful accounts at December 31, 2009 was $3.2 million compared to $3.5 million at December 31, 2008.

Long-Lived Assets, Intangibles and Goodwill

Property, plant and equipment are carried at cost. Major renewals and improvements are capitalized and depreciated over the respective asset's remaining useful life. Maintenance and repair costs are charged to expense as incurred. When long-lived assets are sold or retired, the remaining costs and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in income.

Property, plant and equipment held and used is reviewed for impairment whenever events or changes in circumstances indicate the carrying amounts may not be recoverable over the remaining service life. Indicators of possible impairment include extended periods of idle use or significant declines in activity levels in regions where specific assets or groups of assets are located.

Provisions for asset impairment are charged to income when the net book value of the assets, or carrying value, is determined to be unrecoverable and the carrying value exceeds the fair value of the assets. Fair value is the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants. We did not record any material impairment charges relating to our long-lived assets held for use during the years ended December 31, 2009, 2008 or 2007.

We review our goodwill, the excess of the purchase price over the fair value of net assets acquired in business combinations, at least annually for impairment or more frequently if an event occurs which may indicate impairment during the year. We evaluated assets with indefinite lives, including goodwill and certain intangible assets, for impairment comparing the fair value of our reportable segments to their net carrying value as of the balance sheet date, after excluding inter-company transactions and allocating corporate assets to the reportable segments. Fair value is the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants. If the carrying value of the reportable segment exceeds the fair value determined, impairment may be indicated. If impairment is indicated, the fair value of the reportable segment would be determined. Any remaining goodwill would be deemed impaired and charged to income during the period the impairment was identified. Any subsequent impairment loss could result in a material adverse effect upon our financial position and results of operations. We did not identify a triggering event or record impairment charges relating to our goodwill during the years ended December 31, 2009, 2008 or 2007.

Inventory Valuation Allowances

Our valuation reserve for inventory is based on historical regional sales trends, and various other assumptions and judgments including future demand for this inventory. Should these assumptions and judgments not occur, our valuation allowance would be adjusted to reflect actual results. Our industry is subject to technological change and new product development that could result in obsolete inventory. Our valuation reserve for inventory at December 31, 2009 was $2.2 million compared to $1.7 million at December 31, 2008. If we overestimate demand for inventory, it could result in a material adverse effect upon our financial position and results of operations.

Income Taxes

Our income tax expense includes income taxes of The Netherlands, the U.S. and other foreign countries as well as local, state and provincial income taxes. We recognize deferred tax assets or liabilities for the differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the years in which the asset is recovered or the liability is settled. Any valuation allowance recorded is based on estimates and assumptions of taxable income into the future and a determination is made of the magnitude of deferred tax assets which are more likely than not to be realized. Valuation allowances of our net deferred tax assets aggregated $10.7 million and $9.4 million at December 31, 2009 and 2008, respectively. If these estimates and related assumptions change in the future, we may be required to record additional valuation allowances against our deferred tax assets and our effective tax rate may increase which could result in a material adverse effect on our financial position, results of operations and cash flows. We have not provided for deferred taxes on the unremitted earnings of certain subsidiaries that we consider to be permanently reinvested. Should we make a distribution of the unremitted earnings of these subsidiaries, we may be required to record additional taxes. We record a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We also recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Stock-Based Compensation

We have two stock-based compensation plans, as described in further detail in Note 13 to our Consolidated Financial Statements. For new awards issued and awards modified, repurchased or cancelled, the compensation expense is equal to the fair value of the award at the date of the grant and is recognized in the Consolidated Statement of Operations for those awards earned over the requisite service period of the award.

Pensions and Other Postretirement Benefits

We maintain a defined benefit pension plan for substantially all of our Dutch employees hired before 2007. As required by current accounting standards, we recognize net periodic pension costs associated with this plan in income from current operations and recognize the unfunded status of the plan, if any, as a long-term liability. In addition, we recognize as a component of other comprehensive income, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost. The projection of benefit obligation and fair value of plan assets requires the use of assumptions and estimates. Actual results could differ from those estimates. See Note 10, Pensions and Other Postretirement Benefit Plans. Furthermore, we sponsor several defined contribution plans for the benefit of our employees. We expense these contributions in the period the contribution is made.

Estimates

The preparation of financial statements in accordance with U.S. GAAP requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We evaluate our estimates on an ongoing basis and determine the adequacy of our estimates based on our historical experience and various other assumptions that we believe are reasonable under the circumstances. By nature, these judgments are subject to an inherent degree of uncertainty. We consider an accounting estimate to be critical if it is highly subjective and if changes in the estimate under different assumptions would result in a material impact on our financial condition and results of operations. The following table summarizes key estimates and assumptions used to prepare our Consolidated Financial Statements for the years ended December 31, 2009, 2008 or 2007.

Account	Nature of Estimates Required	Assumptions Used
Allowance for doubtful accounts	We evaluate whether client receivables are collectible.	See "Allowance for Doubtful Accounts."
Inventory reserves	We forecast client demand, considering changes in technology which could result in obsolescence.	See "Inventory Valuation Allowances."
Depreciation and amortization	We estimate the useful lives and salvage values of our assets.	Useful lives assigned reflect our best estimate based on historical data of the respective asset's useful life and salvage value. These assets could become impaired if our operating plans or business environment changes.
Pensions and other postretirement benefits	We utilize an actuary to assist in determining the value of the projected benefit obligation under a Dutch pension plan. This valuation requires various estimates and assumptions concerning mortality, future pay increases and discount rate used to value our obligations. In addition, we recognize net periodic benefit cost based upon these estimates.	The actuarial assumptions used are based upon professional judgment and historical experience, including trends in mortality rates, and credit market rates (discount rate).
Stock-based compensation	We evaluate the probability that certain of our stock-based plans will meet targets established within the respective agreements and result in the vesting of such awards. In addition, we derive an estimated forfeiture rate that is used in calculating the expense for these awards.	See "Stock-Based Compensation." Comparisons to our stock price, a return on our stock price compared to certain stock indices or a return on equity calculation.
Income taxes	We estimate the likelihood of the recoverability of our deferred tax assets (particularly, net operating loss carry-forwards).	See "Income Taxes." We examine our historical and projected operating results, review the eligible carry-forward period and tax planning opportunities and consider other relevant information. Changes in tax laws for the jurisdictions in which we operate could significantly impact our estimates.
Long-lived assets, intangibles and goodwill	We evaluate the recoverability of our assets periodically, but at least annually, by examining current and projected operating results to identify any triggering events, which may indicate impairment. We compare the carrying value of the assets to a projection of fair value, utilizing judgment as to the identification of reporting units, the allocation of corporate assets amongst reporting units and the determination of the appropriate discount rate.	See "Long-Lived Assets, Intangibles and Goodwill." Our impairment analysis is subjective and includes estimates based on assumptions regarding future growth rates, interest rates and operating expenses.

Off-Balance Sheet Arrangements

Other than normal operating leases, we do not have any off–balance sheet financing arrangements such as securitization agreements, liquidity trust vehicles, synthetic leases or special purpose entities. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such financing arrangements.

Operating Results for the Year Ended December 31, 2009 Compared to the Years Ended December 31, 2008 and 2007

We evaluate our operating results by analyzing revenues, operating income margin (defined as operating income divided by total revenue) and net income margin (defined as net income divided by total revenue). Since we have a relatively fixed cost structure, increases in revenues generally translate into higher operating income margin and income margin percentages. Results for the years ended December 31, 2009, 2008 and 2007 are summarized in the following chart:

Return to table of contents

Service Revenues

Service revenues decreased to $553.8 million for 2009 from $597.7 million for 2008 and $508.0 million for 2007. The decrease in revenue in 2009 compared with 2008 was the result of a significant decline in oil and gas prices and drilling activity from record highs reached mid-year 2008; however, this decrease was softened by our improved penetration of international markets in 2009. Activity in North America is significantly down from 2008 levels; however, the United States began showing improvement in the fourth quarter of 2009. Our large scale core analyses and reservoir fluid projects combined with our fluid and derived products inspection, calibration and assay work continue to provide meaningful revenue streams in the Middle East, Asia-Pacific, offshore deepwater regions of the Gulf of Mexico and the southern-Atlantic margins off the coast of West Africa and Brazil.

Product Sale Revenues

Product sale revenues decreased to $141.8 million for 2009, from $183.1 million for 2008 and $162.5 million for 2007. Our product sales revenues were impacted by the significant decline in the North American drilling activity during 2008 and 2009; however, our revenues declined at a much lower rate compared to the 42% decrease in the average North American rig count from 2008 to 2009. We have been able to offset the drop in demand by gaining additional market share primarily through the acceptance of our specialized reservoir optimizing technologies introduced over the last three years. These specialized reservoir optimizing technologies are focused on high-end well completion and stimulation programs mainly in the Haynesville, Marcellus and Eagle Ford shale plays and in multi-stage completions in the Bakken oil-shale play. The incremental improvement in revenue from 2007 to 2008 was consistent with the higher revenues we experienced for our services, a 13% year-over-year increase for the period ended December 31, 2008. This increase was primarily the result of continued market penetration and acceptance of new reservoir optimizing technologies introduced in 2007 and 2008 coupled with improved pricing and the continued increase in drilling activity on a global basis during such period, specifically for natural gas in the North American markets which resulted in higher demand for our well completion products.

Cost of Services

Cost of services decreased to $352.0 million for 2009 from $387.1 million for 2008 and $336.2 million for 2007. As a percentage of service revenue, cost of services have steadily decreased to 63.6% in 2009 from 64.8% in 2008 and 66.2% in 2007. The continuous decline in the cost of services relative to service revenue has been primarily a result of proactive personnel expense control actions put in place to protect against potential market declines and our continued focus on emphasizing higher value and thus higher margin services.

Cost of Product Sales

Cost of product sales decreased to $105.7 million for 2009 from $127.6 million for 2008 and $113.0 million for 2007. As a percentage of product sale revenues, cost of sales increased to 74.6% for 2009 compared to 69.7% for 2008 and 69.6% for 2007. The reduction in margins from 2008 to 2009 came primarily from reduced manufacturing efficiencies associated with lower production levels as a result of the significant decline in North American drilling activity. The improvement in margins for 2008 as compared to 2007 was largely attributable to the growing demand for our new technologies which are our higher margin products, from an overall increase in sales, continued efforts to enhance our manufacturing efficiencies, improved pricing on newly released products and improved inventory management.

General and Administrative Expense

General and administrative expenses include corporate management and centralized administrative services that benefit our operations. General and administrative expenses were 4% lower in 2009 than in 2008. These expenses also decreased in 2008 by 6.5% in comparison to 2007 primarily due to lower compensation benefits for certain members of management.

Depreciation and Amortization Expense

Depreciation and amortization expense increased $2.0 million in 2009 compared to 2008, and increased $2.3 million in 2008 compared to 2007. These increases in depreciation and amortization expense were primarily due to normal capital expenditures for replacement of existing equipment and investment in areas of growth.

Total other expense (income), net	$	(3,202	)	$	5,580		$	(15,915	)

During the later part of 2008, the USD strengthened significantly against most other currencies across the globe. As a result, we experienced unusually high losses in foreign currency translation for the fourth quarter of 2008. In 2009, most foreign currencies partially recovered some of the value lost in 2008 against the USD, and as a result we experienced foreign currency translation gains. However, virtually all the foreign currency gains experienced in 2009 were offset by our foreign currency losses related to Venezuela.

In 2008, we revised our estimate of a contingent liability associated with non-income related taxes, and as a result, a charge to income of $5.0 million was recorded in the Consolidated Statements of Operations to Other Expense (Income), net. This contingent liability is included in Other Long-term Liabilities in the Consolidated Balance Sheet at December 31, 2008. As a result of finalizing a settlement agreement for $2.5 million, we released the remaining $2.5 million during the second quarter of 2009.

In 2008, we recorded a gain of $1.1 million in connection with the sale of a small office building.

In 2007, we moved our administrative and operational offices to a building better suited for our current operating activities in Russia and sold our building in Moscow for approximately $13.1 million which resulted in a gain of $10.2 million.

Gain on Repurchase of Senior Exchangeable Notes

During the fourth quarter of 2008, we repurchased $61.3 million of our senior exchangeable notes at a discount which resulted in a gain of $2.8 million.

Interest Expense

Interest expense decreased $6.1 million in 2009 compared to 2008, and increased $3.2 million in 2008 compared to 2007. At the end of the second quarter of 2008, the early conversion feature of the convertible Notes was triggered. This resulted in the Notes being classified as short-term and required the write-off of $3.5 million in deferred debt acquisition costs to interest expense in the second quarter of 2008. In the fourth quarter of 2008, we repurchased approximately 20% of the convertible Notes at a discount. This discount is being amortized to interest expense using the effective interest method. Consequently, the monthly amortization of the debt discount is lower in 2009. Cash interest expense was only $0.6 million, $0.8 million and $0.7 million for the years ended December 31, 2009, 2008 and 2007, respectively.

Income Tax Expense

Income tax expense increased $0.4 million in 2009 compared to 2008 despite a decrease in net income before taxes due primarily to the recapture of tax consolidation benefits in Mexico with respect to recent changes in the tax laws and additional taxes provided for specific tax uncertainties in the various jurisdictions in which we operate. Income tax expense increased $2.5 million in 2008 compared to 2007 due to an increase in earnings of $22.7 million offset by a decrease in the tax rate. The effective tax rate was 33.4% for 2009, 30.2% for 2008 and 32.8% for 2007. The higher tax rate for 2009 was due to the recapture of tax consolidation benefits in Mexico with respect to recent changes in the tax laws, additional taxes provided for specific tax uncertainties in the various jurisdictions in which we operate and the operational losses and asset write down in Venezuela that are without tax benefit. The higher tax rate for 2007 compared to 2008 was due to an additional accrual for an ongoing tax uncertainty in one of our taxing jurisdictions.

Reservoir Description

Revenues for our Reservoir Description segment decreased by 4.7% in 2009 compared to 2008, after growing 16.3% in 2008 compared to 2007. The revenue decrease in 2009 was the result of a significant decline in oil and gas prices and drilling activity from record highs in 2008, which affected demand for some of the services in this segment. Due to our significant international operations and projects such as our reservoir rock and reservoir fluids characterization projects, this segment has continued to improve its operating income and margins despite the recent downturn experienced throughout the industry. During 2009, we have experienced increased demand for our services in the Middle East and Asia-Pacific and for our continued large scale core analyses studies as well

as crude oil and derived petroleum products characterization studies on a global basis. Other areas that continue to provide revenue growth are the continued expansion of worldwide deepwater projects in West Africa, Brazil and the Gulf of Mexico and the North American gas shale plays in the Eagle Ford, Haynesville, Muskwa and other active fields. Revenue increases in 2008 over 2007 resulted from continued demand for our reservoir rock and especially for our reservoir fluids characterization services in the Middle East and Asia-Pacific, along with our reservoir optimizing technologies in several North American projects related to the Canadian oil sands, tight gas sands and multiple gas-shale reservoirs. The revenue growth was also driven, in part, by the continued expansion of worldwide deepwater projects.

Operating income and operating income margin increased in 2009 from 2008 due to continued emphasis on higher value and thus higher margin services on internationally-based development and production-related crude oil projects, in addition to the de-emphasis of the more cyclical exploration-related projects. There also has been a continued emphasis on controlling costs. Operating income remained flat and operating income margin decreased from 2007 to 2008 due to unusually large foreign exchange losses incurred during the second half of 2008 which offset the effect of our continued growth of higher value-added and consequently higher margin products.

Production Enhancement

Revenues for our Production Enhancement segment decreased 21.3% in 2009 compared to 2008, primarily due to the significant decline in North American drilling activity. However, during this period, where the average rig count for North America has dropped 42%, we have maintained our focus on high-end well completion and stimulation programs, which has resulted in improved market penetration and client acceptance of our well perforating and completion products and our fracture diagnostic services and our concentrated focus on the Haynesville, Marcellus, and Eagle Ford Shale developments. As a result, we have been able to moderate the decline in our revenues versus the declining drilling activity levels when comparing year over year. The downward trend in the North America rig count that started in the latter half of 2008 appears to have stabilized. Revenues for our Production Enhancement segment grew 19.7% in 2008 compared to 2007, primarily due to increased market penetration and client acceptance of our well perforating and completion products and fracture diagnostic services which are being used in tight gas sands and gas-shale reservoirs. With the increase in drilling activities, demand for our well perforating and completion products and diagnostic services has also increased, facilitated by the continued improvements in our technologies such as the SpectraChem®, SuperHERO™, and SuperHERO Plus+™.

Operating income for this segment decreased to $65.1 million in 2009 from $93.0 million in 2008, a decrease of 30.0%. The decrease in margins in 2009 was primarily driven by the significant decline in North American drilling activities, and as a result, we have reduced manufacturing levels which has negatively impacted the efficiency of our manufacturing operations. Additionally, reduced demand in North America has decreased margins due to pressure on pricing; however, this has been partially offset by our continued market penetration of higher-margin services including our proprietary and patented fracture diagnostic technologies, such as our SpectraScan™ and recently introduced SpectraChem Plus® tracer service coupled with an on-going emphasis on controlling costs. Operating income for this segment increased to $93.0 million in 2008 from $68.9 million in 2007, an increase of 35.0%. The improvement in 2008 over 2007 was due primarily to increased sales of higher-margin services and products including our proprietary and patented fracture diagnostic technologies, such as SpectraScan™ and SpectraChem® tracer services. Additionally, the demand for our technology in fracture diagnostics continued to increase as drilling activity increased in unconventional gas reservoirs. Also driving the increase was the higher-margin GTX-SPAN™ casing patches and the recently introduced SuperHERO™ and SuperHERO Plus+™ perforating charges and gun systems for which sales have increased with global demand, while improvements in manufacturing efficiencies resulted in higher productivity per employee and lower overall costs per unit.

Reservoir Management

Revenues for our Reservoir Management segment decreased to $50.0 million in 2009 from $52.4 million in 2008 and $51.3 million in 2007. This decline was a result of lower demand for our permanent well monitoring instrumentation in Canada oil sands and our decision to stop selling these systems in Venezuela. We continued to grow revenue due to continuation of our multi-client reservoir studies, especially studies pertaining to unconventional gas reservoirs, to partially offset reduced demand for our reservoir monitoring systems. Additional studies recently initiated include the expansion of our unconventional natural gas reservoir studies to different regions in North America, deepwater studies off the coast of Brazil and West Africa, and a study on the petroleum potential of offshore Vietnam. Significant studies in 2009 and 2008 were Reservoir Characterization and Production Properties of Gas Shales and Geological, Petrophysical, and Geomechanical Properties of Tight Gas Sands and several other proprietary studies.

Operating income for this segment decreased to $14.6 million in 2009 compared to $16.2 million in 2008 and $14.7 million in 2007. The decrease was primarily due to the decline in sales of our reservoir monitoring systems.

Liquidity and Capital Resources

General

We have historically financed our activities through cash on hand, cash flows from operations, bank credit facilities, equity financing and the issuance of debt. Cash flow from operating activities provides the primary source of funds to finance operating needs, capital expenditures and our share repurchase program. If necessary, we supplement this cash flow with borrowings under bank credit facilities to finance some capital expenditures and business acquisitions. As we are a Netherlands holding company, we conduct substantially all of our operations through subsidiaries. Our cash flow is largely dependent upon the ability of our subsidiaries to pay cash dividends or otherwise distribute or advance funds to us.

We utilize the non-GAAP financial measure of free cash flow to evaluate our cash flows and results of operations. Free cash flow is defined as net cash provided by operating activities less capital expenditures. Management believes that free cash flow provides useful information to investors as it represents the cash, in excess of capital expenditures, available to operate the business and fund non-discretionary obligations. The following table reconciles this non-GAAP financial measure to the most directly comparable measure calculated and presented in accordance with U.S. GAAP for the years ended December 31, 2009, 2008 and 2007:

	Year Ended December 31,
Free Cash Flow Calculation	2009			2008			2007
Net cash provided by operating activities	$	181,873		$	155,207		$	125,695
Less: capital expenditures		(17,289	)		(30,950	)		(23,827	)
Free cash flow	$	164,584		$	124,257		$	101,868

The increase in free cash flow in 2009 compared to 2008 and 2007 was due to an increase in cash provided by operating activities primarily as a result of improvements in working capital and lower capital expenditures. Working capital was $284.1 million and $140.0 million at December 31, 2009 and 2008, respectively.

Cash Flows

The following table summarizes cash flows for the years ended December 31, 2009, 2008 and 2007 (in thousands):

	Year Ended December 31,
	2009			2008			2007
Cash provided by/(used in):
Operating activities	$	181,873		$	155,207		$	125,695
Investing activities		(18,540	)		(41,108	)		(19,975	)
Financing activities		(18,426	)		(103,578	)		(134,326	)
Net change in cash and cash equivalents	$	144,907		$	10,521		$	(28,606	)

The increase in cash flow from operating activities in 2009 compared to 2008 was primarily due to continued strong collections of receivables, approximately $9 million of advance payments from customers and deferred tax liabilities offset by a decrease in net income. The increase in cash flow from operating activities in 2008 compared to 2007 was primarily due to an increase in net income, a decrease in prepaid and other current assets and a reduction in growth of accounts receivable offset by an increase in inventory and a decrease in other long term liabilities.

Cash flow used in investing activities decreased $22.6 million in 2009 over 2008 due to reduced capital expenditures, and acquisition activity. Cash flow used in investing activities increased $21.1 million in 2008 over 2007 due to an increase in capital expenditures, an increase in acquisitions and a reduction in cash proceeds from the sale of fixed assets.

Cash flow used in financing activities in 2009 decreased $85.2 million compared to 2008 due to a reduction in the repurchase of our common shares and repurchase of our senior exchangeable notes partially offset by proceeds from the sale of the note hedge claim. Cash flow used in financing activities in 2008 decreased $30.7 million compared to 2007 due to a reduction in the repurchase of our common shares offset by additional debt payments from the repurchase of our Notes and the payment of cash dividends in 2008. Additionally, cash received from exercised stock options and the tax benefit received from stock-based payments was $35.2 million lower in 2008 as compared to 2007.

Return to table of contents

During the year ended December 31, 2009, we repurchased 139,129 shares of our common stock for an aggregate amount of $9.4 million, or an average price of $67.48 per share. The repurchase of shares in the open market is at the discretion of management pursuant to shareholder authorization. We regard these treasury shares as a temporary investment which may be used to fund restricted shares that vest, stock options that are exercised, finance future acquisitions or to prepare for any obligation we may have to deliver common shares to the holders of our Senior Exchangeable Notes or pursuant to our warrants. Under Dutch law and subject to certain Dutch statutory provisions and shareholder approval, we can hold a maximum of 50% of our issued shares in treasury. We currently have shareholder approval to hold 25.6% of our issued share capital in treasury. On January 29, 2009 at an extraordinary shareholder meeting, our shareholders authorized the extension of our share repurchase program of up to 25.6% of our issued share capital from time to time for an 18 month period until July 29, 2010. The extraordinary meeting authorized the Management Board to repurchase up to 10% of our issued share capital which may be used for any legal purpose and an additional 15.6% of our issued share capital which may only be used for the satisfaction of any obligation we may have to deliver shares pursuant to our Senior Exchangeable Notes when they become due or pursuant to our warrants. We believe this share repurchase program has been beneficial to our shareholders. Our share price has increased from $8.05 per share in 2002, when we began to repurchase shares, to $118.12 per share on December 31, 2009, an increase of over 1,367%.

Credit Facilities and Available Future Liquidity

In November 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of Senior Exchangeable Notes due 2011 (the "Notes") to qualified institutional buyers. The Notes bear interest at a rate of 0.25% per year and are fully and unconditionally guaranteed by Core Laboratories N.V. The Notes are exchangeable into shares of Core Laboratories N.V. common stock under certain circumstances at a current conversion rate of 10.8012 shares per $1,000 principal amount of Notes, subject to anti-dilution adjustments. Upon exchange, holders will receive cash up to the principal amount, and any excess exchange value will be delivered in Core Laboratories N.V. common shares. The Notes bear interest at a rate of 0.25% per year payable semi-annually on May 6 and November 6 of each year, beginning on May 6, 2007.

We maintain a revolving credit facility (the "Credit Facility") with an aggregate borrowing commitment of $100.0 million, with an option to increase the commitment under the credit facility to $150.0 million, if certain conditions are met. The Credit Facility bears interest at variable rates from LIBOR plus 0.5% to a maximum of LIBOR plus 1.125%. Any outstanding balance under the Credit Facility is due when it matures in December 2010 and only requires semi-annual interest payments until maturity. These interest payments are based on the interest period selected. Our available borrowing capacity under the Credit Facility at December 31, 2009 was $87.5 million. Our available capacity is reduced by outstanding letters of credit and performance guarantees and bonds totaling $12.5 million at December 31, 2009 relating to certain projects in progress.

The terms of the Credit Facility require us to meet certain financial covenants, including, but not limited to, certain operational and minimum equity and cash flow ratios. We believe that we are in compliance with all such covenants contained in our credit agreement. All of our material wholly owned subsidiaries are guarantors or co-borrowers under the Credit Facility.

In addition to our repayment commitments under our credit facilities and the Notes, we have capital lease obligations relating to the purchase of equipment, and non-cancelable operating lease arrangements under which we lease property including land, buildings, office equipment and vehicles.

The following table summarizes our future contractual obligations under these arrangements (in thousands):

	Total		Less than 1 year		1-3 Years		3-5 Years		More than 5 Years
Contractual Obligations:

Long-term debt (1)	$	238,658	$	-	$	238,658	$	-	$	-
Operating leases		23,930		6,682		8,809		4,706		3,733

Total contractual obligations	$	265,309	$	9,403	$	247,467	$	4,706	$	3,733

(1) Not included in the above balances are anticipated cash payments for interest of $0.6 million a year for 2010-2011 for a total of $1.2 million on the long-term debt that is due November 2011.
(2) Our Dutch pension plan requires annual employer contributions. Amounts payable in the future will be based on future workforce factors which cannot be projected beyond one year.

Return to table of contents

We have no significant purchase commitments or similar obligations outstanding at December 31, 2009. Not included in the table above are uncertain tax positions that we have accrued for at December 31, 2009. We have not included accruals for uncertain tax positions in the table above, as the amounts and timing of payment, if any, are uncertain.

At December 31, 2009, we had tax net operating loss carry-forwards in various tax jurisdictions of approximately $36.5 million. Although we cannot be certain that these operating loss carry-forwards will be utilized, we anticipate that we will have sufficient taxable income in future years to allow us to fully utilize the carry-forwards that are not subject to a valuation allowance as of December 31, 2009. If unused, these carry-forwards which are subject to expiration may expire during the years 2010 through 2019. During 2009, $2.3 million of operating loss carry-forwards which carried a full valuation allowance expired unused.

We expect our investment in capital expenditures to be approximately $20 million to $25 million in 2010 which will be used to fund our growth through the purchase of instrumentation, tools and equipment along with expenditures to replace obsolete or worn-out instrumentation, tools and equipment and to consolidate certain facilities to gain operational efficiencies. In addition, we plan to continue to (i) repurchase our common shares on the open market through our stock repurchase program, (ii) repurchase our Notes, (iii) pay a dividend or (iv) acquire complimentary technologies. Our ability to continue these initiatives depends on, among other things, market conditions and our ability to generate free cash flow.

Our ability to maintain and increase our operating income and cash flows is largely dependent upon continued investing activities. We believe our future cash flows from operating activities, supplemented by our borrowing capacity under existing facilities and our ability to issue additional equity should be sufficient to meet our contractual obligations, capital expenditures, working capital needs and to finance future acquisitions.

Accounting Pronouncements

In June 2009, the FASB issued the FASB Accounting Standards Codification ("Codification"). The Codification has become the single source for all authoritative GAAP recognized by the FASB to be applied for financial statements issued for periods ending after September 15, 2009. We applied the Codification to our Annual Report on Form 10-K for the period ending December 31, 2009. The Codification does not change GAAP and did not have an effect on our financial position or results of operations.

In June 2009, the FASB issued an update to ASC 810-10, Consolidation –Variable Interest Entities, which becomes effective as of the beginning of the first annual reporting period beginning after November 15, 2009. This new guidance requires revised evaluations of whether entities represent variable interest entities, modifies the analysis by which a controlling interest of a variable interest entity is determined, requires ongoing assessments of control over such entities and provides guidance on the additional disclosure requirements for variable interests. We do not expect this new guidance to have a material impact on our financial statements.

Forward-Looking Statements

This Form 10-K and the documents incorporated in this Form 10-K by reference contain forward-looking statements. These "forward-looking statements" are based on an analysis of currently available competitive, financial and economic data and our operating plans. They are inherently uncertain and investors should recognize that events and actual results could turn out to be significantly different from our expectations. By way of illustration, when used in this document, words such as "anticipate," "believe," "expect," "intend," "estimate," "project," "will," "should," "could," "may," "predict" and similar expressions are intended to identify forward-looking statements. You are cautioned that actual results could differ materially from those anticipated in forward-looking statements. Any forward-looking statements, including statements regarding the intent, belief or current expectations of us or our management, are not guarantees of future performance and involve risks, uncertainties and assumptions about us and the industry in which we and Core Lab operate, including, among other things:

-	our ability to continue to develop or acquire new and useful technology;

-	the realization of anticipated synergies from acquired businesses and future acquisitions;

-	our dependence on one industry, oil and gas, and the impact of commodity prices on the expenditure levels of our customers;

-	competition in the markets we serve;

Return to table of contents

-	the risks and uncertainties attendant to adverse industry, political, economic and financial market conditions, including stock prices, government regulations, interest rates and credit availability;

-	unsettled political conditions, war, civil unrest, currency controls and governmental actions in the numerous countries in which we operate;

-	changes in the price of oil and natural gas;

-	integration of acquired businesses; and

-	the effects of industry consolidation.

Our businesses depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, a sustained increase or decrease in the price of natural gas or oil, which could have a material impact on exploration, development and production activities, could also materially affect our financial position, results of operations and cash flows.

The above description of risks and uncertainties is by no means all-inclusive, but is designed to highlight what we believe are important factors to consider. For a more detailed description of risk factors, please see "Item 1A. Risk Factors" in this Form 10-K and our reports and registration statements filed from time to time with the SEC.

All forward-looking statements in this Form 10-K are based on information available to us on the date of this Form 10-K. We do not intend to update or revise any forward-looking statements that we may make in this Form 10-K or other documents, reports, filings or press releases, whether as a result of new information, future events or otherwise.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

We are exposed to market risk, which is the potential loss arising from adverse changes in market prices and rates. We have not entered, or intend to enter, into derivative financial instruments for hedging or speculative purposes. We do not believe that our exposure to market risks, which are primarily related to interest rate changes, is material.

Interest Rate Risk

From time to time, we are exposed to interest rate risk on our Credit Facility debt, which carries a variable interest rate. At December 31, 2009, we had no variable rate debt outstanding.

As a result of the political and financial instability in Venezuela, the Bolivar ("VEB") declined in value relative to other currencies. In January 2010, the Venezuelan government announced that the fixed official exchange rate would be changed to a dual system that includes a rate of 2.6 VEB per USD for food and heavy machine importers and a rate of 4.3 VEB per USD for all others from 2.15 VEB per USD. However, the freely traded or parallel market valued the exchange rate at approximately 5 VEB per USD at year end. Management determined the parallel market rate is the most appropriate rate to use for remeasuring the financial statements. Using the parallel market rate, we recognized a devaluation of our net monetary assets resulting in a foreign exchange loss of approximately $1.3 million in the fourth quarter of 2009. At December 31, 2009, our net monetary assets denominated in VEB in Venezuela were $1.2 million. We continue to de-emphasize our operations and financial position in this country.

Credit Risk

Our financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. All cash and cash equivalents are on deposit at commercial banks or investment firms. Our trade receivables are with a variety of domestic, international and national oil and gas companies. Management considers this credit risk to be limited due to the creditworthiness and financial resources of these financial institutions and companies.

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, under the supervision of and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our 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, as amended (the "Exchange Act"), as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2009 at the reasonable assurance level.

Our management does not expect that our disclosure controls and procedures or our system of internal control over financial reporting will prevent all errors and all fraud. Further, the design of disclosure controls and internal control over financial reporting must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as that term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our 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.

Return to table of contents

Our management, under the supervision of and with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of our internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth in Internal Control − Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment using these criteria, our management determined that our internal control over financial reporting was effective as of December 31, 2009.

The effectiveness of our internal control over financial reporting as of December 31, 2009, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control over Financial Reporting

There was no change in our system of internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended December 31, 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

None.

PART III

The information required by Part III (Items 10 through 14) is incorporated by reference from our definitive proxy statement to be filed in connection with our 2010 annual meeting of shareholders pursuant to Regulation 14A under the Exchange Act. We expect to file our definitive proxy statement with the SEC within 120 days after the close of the year ended December 31, 2009.

Report of Independent Registered Public Accounting Firm

To the Supervisory Board of Directors and Shareholders of Core Laboratories N.V.:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Core Laboratories N.V. (a Netherlands corporation) and its subsidiaries at December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, the financial statement schedule, 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 appearing under Item 9A of Part II of this Form 10-K. Our responsibility is to express opinions on these financial statements, on the financial statement schedule 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.

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for uncertain tax positions in 2007. Additionally, as discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for certain convertible debt instruments, effective January 1, 2009.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2009

1. DESCRIPTION OF BUSINESS

Core Laboratories N.V. ("Core Laboratories", "we", "our" or "us") is a Netherlands limited liability company. We were established in 1936 and are one of the world's leading providers of proprietary and patented reservoir description, production enhancement and reservoir management services to the oil and gas industry. These services are directed toward enabling our clients to improve reservoir performance and increase oil and gas recovery from their producing fields. We have over 70 offices in more than 50 countries and have approximately 4,900 employees.

Our business units have been aggregated into three complementary segments which provide products and services for improving reservoir performance and increasing oil and gas recovery from new and existing fields: (1) Reservoir Description, (2) Production Enhancement and (3) Reservoir Management. For a description of product types and services offered by these business segments, see Note 15, Segment Reporting.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP"), and include the accounts of Core Laboratories and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. All inter-company transactions and balances have been eliminated in consolidation. The equity method of accounting is used to record our interest in investments in which we have less than a majority interest and do not exercise significant control. We use the cost method to record certain other investments in which we own less than 20% of the outstanding equity and do not exercise significant control. We record non-controlling interest associated with consolidated subsidiaries that are less than 100% owned.

Change in Accounting Principle

On January 1, 2009, we adopted the accounting guidance issued for debt with conversion and other options, which specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity's nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. The adoption of these accounting standards impacted the historical accounting for our Notes and has been applied retrospectively to all periods presented.

The cumulative effect of the change in accounting principle on periods prior to those presented are an increase to Additional Paid in Capital of $55.9 million, an increase to Deferred Tax Liabilities of $32.7 million, a decrease to Other Assets of $1.3 million with an offset to Retained Earnings of $1.6 million and a discount on the Notes of $88.3 million. The impact to net income was a decrease of $12.1 million and $9.9 million and a decrease to diluted earnings per share of $0.52 and $0.41 for the years ended December 31, 2008 and 2007, respectively.

Subsequent Events

We have performed an evaluation of subsequent events through February 18, 2010, which is the date the financial statements were issued.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We evaluate our estimates on an ongoing basis and utilize our historical experience, as well as various other assumptions that we believe are reasonable in a given circumstance, in order to make these estimates. Actual results could differ from our estimates, as assumptions and conditions change.

The following accounts, among others, require us to use critical estimates and assumptions:

Return to index

F-7

-	allowance for doubtful accounts;

-	inventory reserves;

-	depreciation and amortization;

-	pensions and other postretirement benefits;

-	stock-based compensation;

-	income taxes; and

-	long-lived assets, intangibles and goodwill.

Accounting policies relating to these accounts and the nature of these estimates are further discussed under the applicable caption. For each of these critical estimates it is at least reasonably possible that changes in these estimates will occur in the short term which may impact our financial position or results of operations.

Cash and Cash Equivalents

Cash and cash equivalents include all short-term, highly liquid instruments purchased with an original maturity of three months or less. These items are carried at cost, which approximates market value. For the years ended December 31, 2009 and 2008, cash equivalents included time deposits and money market investment accounts.

Concentration of Credit Risk

Our financial instruments that potentially subject us to concentrations of credit risk relate primarily to cash and cash equivalents and trade accounts receivable. All cash and cash equivalents are on deposit at commercial banks or investment firms with significant financial resources. Our trade receivables are with a variety of domestic, international and national oil and gas companies. We had no clients who provided more than 10% of our revenues for the years ended December 31, 2009, 2008 and 2007. We consider our credit risk related to trade accounts receivable to be limited due to the creditworthiness and financial resources of our clients. We evaluate our estimate of the allowance for doubtful accounts on an on-going basis throughout the year.

Accounts Receivable

Trade accounts receivable are recorded at their invoiced amounts and do not bear interest. We perform ongoing credit evaluations of our clients and monitor collections and payments in order to maintain a provision for estimated uncollectible accounts based on our historical collection experience and our current aging of client receivables outstanding, in addition to client's representations and our understanding of the economic environment in which our clients operate. Based on our review we establish or adjust allowances for specific customers and the accounts receivable as a whole, and recognize expense. When an account is determined to be uncollectible, we charge the receivable to our allowance for doubtful accounts. Our allowance for doubtful accounts totaled $3.2 million and $3.5 million at December 31, 2009 and 2008, respectively.

Inventories

Inventories consist of manufactured goods, materials and supplies used for sales or services to clients. Inventories are stated at the lower of cost or estimated net realizable value, and are reflected net of valuation reserves. Inventory costs are recorded at standard cost which approximates the first-in, first-out method.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets are comprised primarily of income tax receivable of $24.9 million, current deferred tax assets, prepaid insurance, value added taxes and rents.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Allowances for depreciation and amortization are calculated using the straight-line method based on the estimated useful lives of the related assets as follows:

Expenditures for repairs and maintenance are charged to expense as incurred and major renewals and improvements are capitalized. Cost and accumulated depreciation applicable to assets retired or sold are removed from the accounts, and any resulting gain or loss is included in operations.

We review our assets for impairment when events or changes in circumstances indicate that the net book value of property, plant and equipment may not be recovered over its remaining service life. We evaluate our property, plant and equipment for impairment if a triggering event occurs which may indicate that an impairment is probable. Under these circumstances, we compare the sum of the estimated future undiscounted cash flows relating to the asset group, an estimate of realizable value to the carrying value of the assets. If impairment is still indicated, we compare the fair value of the assets to the carrying amount, and recognize an impairment loss for the amount by which the fair value exceeds the carrying value. Fair value is the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants. We did not record any material impairment charges relating to our long-lived assets held for use during the years ended December 31, 2009, 2008 or 2007.

Intangibles and Goodwill

Intangibles include patents, trademarks, and trade names. Intangibles with determinable lives are amortized using the straight-line method based on the estimated useful life of the intangible. Intangibles with indeterminable lives, which consisted primarily of corporate trade names, are evaluated for impairment annually or more frequently if circumstances indicate that impairment has occurred.

We record goodwill as the excess of the purchase price over the fair value of the net assets acquired in acquisitions accounted for under the purchase method of accounting. In accordance with generally accepted accounting standards related to goodwill and other intangible assets, we test goodwill for impairment annually, or more frequently if circumstances indicate that a potential impairment has occurred. See Note 7, Goodwill.

Other Assets

Other assets consisted of the following (in thousands):

	2009		2008

Cash surrender value of life insurance	$	11,717	$	7,614
Investments		319		341
Debt issuance costs		144		288
Other		1,545		884
Total other assets	$	13,725	$	9,127

Cash surrender value of life insurance relates to postretirement benefit plans. See Note 10, Pensions and Other Postretirement Benefit Plans. Investments include our investments in unconsolidated affiliates, accounted for under the equity method, and investments held at cost. We continually evaluate our investments for indicators of a decline in value. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the fair value is less than cost and our intent and ability to hold the investment. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in that reporting period to adjust the carrying value of the investment to its current fair value establishing a new cost basis in the investment. The operations of these entities are in-line with those of our core businesses. These entities are not considered special purpose entities nor do we have special off-balance sheet arrangements through these entities. The debt issuance costs are being amortized over the life of the respective debt instruments.

Income Taxes

We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Consolidated Financial Statements or tax returns.

Deferred tax assets and liabilities are determined based on the difference between the financial statement and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the asset is recovered or the liability is settled. We include interest and penalties from tax judgments in income tax expense.

F-9

On January 1, 2007, we adopted the accounting guidance issued for accounting for uncertainty in income taxes which was issued to create a single model to address accounting for uncertainty in tax positions. This guidance clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements and also provides guidance on derecognition, measurement, classification, interest and penalties, disclosure and transition. Accordingly, we record a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We also recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense. See Note 9, Income Taxes.

Comprehensive Income

Comprehensive income is comprised of net income and other charges or credits to equity that are not the result of transactions with owners. For the years ended December 31, 2009, 2008, and 2007, comprehensive income related to prior service costs and an unrecognized net actuarial loss from a pension plan. See Note 10, Pensions and Other Postretirement Benefit Plans.

Revenue Recognition

Revenues are recognized as services are completed or as product title is transferred. All advance client payments are classified as unearned revenues until services are provided or product title is transferred. We recognize revenue when we determine that the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. Revenues from long-term contracts are recorded as services are rendered in proportion to the work performed. All known or anticipated losses on contracts are provided for currently. Revenues are recorded exclusive of taxes. Training and consulting service revenues are recognized as the services are performed.

Foreign Currencies

Our functional currency is the U.S. Dollar ("USD"). All inter-company financing, transactions and cash flows of our subsidiaries are transacted in USD. Additionally, certain significant operations transact contractual business denominated in the USD. Accordingly, foreign entities remeasure monetary assets and liabilities to USD at year-end exchange rates, while non-monetary items are measured at historical rates. Revenues and expenses are remeasured at the applicable month-end rate, except for depreciation and amortization and certain components of cost of sales, which are measured at historical rates. For the year ended December 31, 2009, we incurred a net remeasurement gain of approximately $0.3 million due to the recent strengthening of the USD, while in the year ended December 31, 2008 we incurred a net remeasurement loss of approximately $6.6 million, and a net remeasurement gain of approximately $1.4 million in the year ended December 31, 2007. These amounts were included in Other Expense (Income), net in the accompanying Consolidated Statements of Operations.

Pensions and Other Postretirement Benefits

We maintain a defined benefit pension plan for substantially all of our Dutch employees. As required by current accounting standards, we recognize net periodic pension costs associated with this plan in income from current operations and recognize the unfunded status of the plan, if any, as a long-term liability. In addition, we recognize as a component of other comprehensive income, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost. The projection of benefit obligation and fair value of plan assets requires the use of assumptions and estimates. Actual results could differ from those estimates. See Note 10, Pensions and Other Postretirement Benefit Plans. Furthermore, we sponsor several defined contribution plans for the benefit of our employees. We expense these contributions in the period the contribution is made.

Non-controlling Interests

On January 1, 2009, we adopted the accounting standards related to non-controlling interests, which requires companies with non-controlling interests to disclose such interests clearly as a portion of equity separate from the parent's equity and the amount of consolidated net income attributable to these non-controlling interests must also be clearly presented on the Consolidated Statements of Operations. In addition, when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary will be initially measured at fair value and recorded as a gain or loss. Upon adopting this accounting standard, we revised our historical presentation of non-controlling interests to be included as part of the total equity and presented the net income relating to non-controlling interests as a separate component of total net income.

Stock-Based Compensation

Earnings Per Share

We compute basic earnings per common share by dividing net income attributable to Core Laboratories N.V. by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common share include additional shares in the weighted average share calculations associated with the incremental effect of dilutive employee stock options, restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands):

	Year Ended December 31,
	2009	2008	2007
Weighted average basic common shares outstanding	22,969	23,008	23,537
Effect of dilutive securities:
Stock options	58	130	333
Contingent shares	16	25	95
Restricted stock and other	189	168	111
Senior exchangeable notes	96	613	332
Weighted average diluted common and potential common shares outstanding	23,328	23,944	24,408

In prior years, we excluded the effect of anti-dilutive shares associated with the exchangeable senior note hedge from the calculation of the diluted weighted average shares. If these shares had been included, the impact would have been a decrease in diluted weighted average shares outstanding of 572,000 shares and 320,000 shares for the years ended December 31, 2008 and 2007, respectively. In December 2009, the exchangeable note hedge was terminated.

In 2006, we sold warrants that give the holders the right to acquire up to 3.2 million of our common shares at a strike price of $124.64 per share. These warrants could have a dilutive impact on our earnings per share if the share price exceeds the strike price of the warrants. Included in the Senior Exchangeable Notes line in the table above, these warrants had no dilutive impact on our earnings per share for the year ended December 31, 2009, as the average share price did not exceed the strike price of the warrants for the period. On October 3, 2008, the dealer of the warrants filed for bankruptcy protection. The warrants have subsequently been purchased by a third party. See Note 8, Debt and Capital Lease Obligations for additional information.

Reclassifications

Certain reclassifications were made to prior year amounts in order to conform to the current year's presentation. These reclassifications had no impact on reported net income for the years ended December 31, 2009, 2008 and 2007.

3. ACQUISITIONS

In 2008, we acquired all of the shares of Catoni Persa, a Turkey-based petroleum testing laboratory specializing in the characterization of crude oil and its derivative products, for $15.0 million. The acquisition resulted in goodwill of $9.8 million and intangibles of $0.3 million which was recorded in the Reservoir Description business segment. This acquisition was made in order to expand our presence in the Black Sea region.

In 2007, we acquired all of the outstanding common shares of Temco, Inc., a Tulsa-based core analysis and reservoir fluids instrument manufacturing business, for $5.5 million. The acquisition resulted in goodwill of $3.8 million and intangibles of $0.8 million which was recorded in the Reservoir Description business segment.

F-11

In 2007, we acquired all of the assets of Entrada Geosciences LLC, a Denver-based geological and field services business for $2.8 million. The acquisition resulted in goodwill of $2.4 million which has been recorded in the Reservoir Description business segment.

The acquisition of these entities did not have a material impact on our Consolidated Balance Sheet or Consolidated Statements of Operations.

Certain intangibles, primarily relating to trade names, are deemed to have an indefinite life and are not amortized. These intangibles are included in an impairment analysis performed at least annually. We performed this impairment testing at December 31, 2009 and no impairments were identified.

7. GOODWILL

The changes in the carrying amount of goodwill for each business segment for the years ended December 31, 2009, 2008 and 2007 were as follows (in thousands):

	Reservoir Description		Production Enhancement		Reservoir Management		Total

Balance at December 31, 2009	$	80,932	$	64,823	$	2,845	$	148,600

In 2008, we acquired all of the shares of Catoni Persa, a Turkey-based petroleum testing laboratory specializing in the characterization of crude oil and its derivative products, for $15.0 million. The acquisition resulted in goodwill of $9.8 million which was recorded in the Reservoir Description business segment.

We test goodwill for impairment at least annually or more frequently if circumstances indicate a potential impairment. For purposes of this test, we compare the fair value of our reporting units, which are our reportable segments, to their net carrying value as of the balance sheet date, after excluding inter-company transactions and allocating corporate assets to the reportable segments. Fair value is the amount that would be received from the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants. If the carrying value of the reportable segment exceeds the fair value determined, impairment may be indicated. If impairment is indicated, the fair value of the reportable segment would be determined, much like a purchase price allocation under the purchase accounting method. Any remaining goodwill would be deemed impaired and charged to income during the period the impairment was identified. We performed this impairment testing at December 31, 2009. We did not identify a triggering event and no impairment was indicated based on our annual test, and therefore, no impairment has been recorded in 2009 or 2008.

8. DEBT AND CAPITAL LEASE OBLIGATIONS

Debt at December 31, 2009 and 2008 is summarized in the following table (in thousands):

	December 31,			December 31,
	2009			2008

Senior exchangeable notes	$	238,658		$	238,658
Discount on senior exchangeable notes		(29,546	)		(44,090	)
Net senior exchangeable notes	$	209,112		$	194,568

In 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of Senior Exchangeable Notes due 2011 (the "Notes"). The Notes bear interest at a rate of 0.25% per year paid on a semi-annual basis and are fully and unconditionally guaranteed by Core Laboratories N.V. Cash interest expense was $0.6 million, $0.8 million and $0.7 million for the years ended December 31, 2009, 2008 and 2007, respectively.

On January 1, 2009, we adopted the accounting guidance issued for debt with conversion and other options, which specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity's nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. See Note 2, Summary of Significant Accounting Policies for the cumulative effect of the change in accounting principle on periods prior to those presented. The adoption of these accounting standards resulted in a discount on the Notes being recorded which is being amortized into interest expense through November 2011.

With the additional amortization of the discount on the Notes, the effective interest rate is 7.48% for the years ended December 31, 2009, 2008 and 2007 which resulted in additional non-cash interest expense of $14.5 million, $16.5 million and $15.8 million for the

F-13

years ended December 31, 2009, 2008 and 2007, respectively. Each Note carries a $1,000 principal amount and is exchangeable into shares of Core Laboratories N.V. under certain circumstances at a conversion rate of $92.58 or 10.8012 per Note. Upon exchange, holders will receive cash up to the principal amount, and any excess exchange value will be delivered in Core Laboratories N.V. common shares. The carrying value of the equity component of the Notes was $84.4 million at December 31, 2009 and December 31, 2008.

The Notes include an early conversion option that is computed quarterly to determine if the Notes can be early converted during the subsequent quarter. During the second quarter of 2008, the early conversion option for the holders of the Notes was enabled. As a result, the Notes could have been converted during the third quarter and were reclassified from a long-term liability to a short-term liability; however, no Note holder exercised their early conversion option before the conversion period ended on September 30, 2008. The related debt acquisition costs of $3.5 million were recorded to interest expense in the second quarter of 2008. The criteria for the early conversion option were not met during the fourth quarter of 2008 and thus the Notes could not be converted during the first quarter of 2009, and accordingly, the Notes were classified as a long-term liability. The criteria for the early conversion option were not met during 2009, and accordingly, the Notes remain classified as a long-term liability. During the fourth quarter of 2008, we repurchased $61.3 million of the Notes at a discount which resulted in a gain of $2.8 million. At December 31, 2009 the Notes were trading at 134% of their face value which would result in $81.1 million of value in excess of the principal. At December 31, 2008, the Notes were trading at 88.1% of their face value.

As part of the issuance of the Notes, we entered into an exchangeable senior note hedge transaction in October 2006 (the "Call Option") through one of our subsidiaries with Lehman Brothers OTC Derivatives Inc. ("Lehman OTC") whereby Lehman OTC is obligated to deliver to us an amount of shares required to cover the shares issuable upon conversion of the Notes. On October 3, 2008, Lehman OTC filed for protection under Chapter 11 of the U.S. Bankruptcy Code. On September 3, 2009, the subsidiary involved in the Call Option filed a proof of claim in the Lehman OTC bankruptcy case related to the Call Option hedge transaction in the amount of $90.1 million. The note hedge contract was formally terminated on December 4, 2009. Subsequently, on December 22, 2009, we sold our claim to a third party for a cash payment of $17.1 million which was recorded to Additional Paid-in Capital on the Consolidated Balance Sheet.

Separate from the Call Option, we also sold to Lehman OTC warrants to purchase up to 3.2 million common shares at a current exercise price of $124.64. The warrants become exercisable beginning in late December 2011 and expire in January 2012. The warrants have subsequently been purchased from Lehman OTC by a third party.

The derivative transactions described above do not affect the terms of the outstanding Notes.

We maintain a revolving credit facility (the "Credit Facility") that allows for an aggregate borrowing capacity of $100.0 million. The Credit Facility provides an option to increase the commitment under the Credit Facility to $150.0 million, if certain conditions are met. The Credit Facility bears interest at variable rates from LIBOR plus 0.5% to a maximum of LIBOR plus 1.125%. Any outstanding balance under the Credit Facility is due in December 2010 when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available borrowing capacity under the Credit Facility at December 31, 2009 was $87.5 million. Our available capacity is reduced by outstanding letters of credit and performance guarantees and bonds totaling $12.5 million at December 31, 2009 relating to certain projects in progress.

The terms of the Credit Facility require us to meet certain financial covenants, including, but not limited to, certain operational and minimum equity and cash flow ratios. We believe that we are in compliance with all such covenants contained in the Credit Facility. All of our material wholly owned subsidiaries are guarantors or co-borrowers under the Credit Facility.

At December 31, 2009, we had tax net operating loss carry-forwards in various tax jurisdictions of approximately $36.5 million. Although we cannot be certain that these operating loss carry-forwards will be utilized, we anticipate that we will have sufficient taxable income in future years to allow us to fully utilize the carry-forwards that are not subject to a valuation allowance as of December 31, 2009. If unused, those carry-forwards which are subject to expiration may expire during the years 2010 through 2019.

Return to index

F-15

At December 31, 2009, we maintained a valuation allowance of $9.8 million on our net operating loss carry-forwards. During 2009, $2.3 million of operating loss carry-forwards which carried a full valuation allowance expired unused.

As a result of our entering into an exchangeable note hedge transaction in 2006, we recorded $31.9 million to our deferred tax asset and to Additional Paid-In Capital. The deferred tax asset was being utilized ratably over the life of the hedge, however, in 2008, as a result of our repurchasing approximately 20% of the Notes, we recognized a proportionate share of the related deferred tax asset as a reduction in our current tax liability.

In 2009, the exchangeable note hedge was terminated in connection with the Lehman bankruptcy. As a result, the Notes and associated note hedge were no longer considered integrated for tax purposes resulting in the Company recognizing a current tax benefit in 2009 and establishing a higher tax basis for the Notes. The tax basis had been $213 million and is now $288 million. As of December 31, 2009, we recorded a net current tax receivable of $20.9 million, the remaining unamortized deferred tax asset of $9.3 million that was originally established for the integrated Note and note hedge was written off, and a deferred tax liability of $18.1 million was established for the resulting difference in tax basis and book basis in the Notes. The result of the transactions associated with terminating the integrated note hedge transaction had no impact on the effective tax rate for 2009 as the current tax benefit was offset by the deferred tax provision.

In connection with the termination of the note hedge, we filed a claim in the bankruptcy proceedings, and subsequently sold the claim to a third party for a cash payment of approximately $17.1 million. The tax effect of $6.5 million associated with the proceeds from the sale of the claim was recorded as a reduction in Additional Paid-In Capital, consistent with the original accounting for the note hedge.

We file income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. We are currently undergoing multiple examinations in various jurisdictions, and the years 1999 through 2008 remain open for examination in various tax jurisdictions in which we operate.

During 2009, payments were made to certain tax jurisdictions, resulting in a reduction to the unrecognized tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	2009			2008			2007

Unrecognized tax benefits at January 1,	$	5,974		$	17,864		$	13,064
Tax positions, current period		4,668			1,001			298
Tax positions, prior period		-			-			4,584

Lapse of applicable statute of limitations		(869	)		(288	)		(7	)
Unrecognized tax benefits at December 31,	$	8,324		$	5,974		$	17,864

Changes in our estimate of unrecognized tax benefits would affect our effective tax rate. The amounts included in the table above for settlements with tax authorities primarily represent cash payments.

Our policy is to record accrued interest and penalties on uncertain tax positions, net of any tax effect, as part of total tax expense for the period. The corresponding liability is carried along with the tax exposure as a non-current payable in Other Long-term Liabilities. We had approximately $3.2 million accrued for the payment of interest and penalties as of December 31, 2009.

During 2009, we recognized tax benefits of $0.2 million relating to tax deductions in excess of book expense for stock-based compensation awards. These tax benefits are recorded to Additional Paid-in Capital to the extent deductions reduce current taxable income as we are able to realize the tax benefits.

10. PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

Defined Benefit Plan

On January 1, 2009 we adopted the accounting standards relating to the disclosure requirements for defined benefit plans, which provides guidance on an employer’s disclosures about plan assets of a defined benefit position or other post retirement plan.

We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees ("Dutch Plan") who were hired prior to 2007 based on years of service and final pay or career average pay, depending on when the employee began participating. Employees are immediately vested in the benefits earned. We fund the future obligations of the Dutch Plan by purchasing investment contracts from a large multi-national insurance company. The investment contracts are purchased annually and

F-16

expire after five years. Each year, as a contract expires, it is replaced with a new contract that is adjusted to include changes in the benefit obligation for the current year and redemption of the expired contract. We determine the fair value of these plan assets with the assistance of an actuary using observable inputs (Level 2). We make annual premium payments, based upon each employee's age and current salary, to the insurance company.

The following table summarizes the change in the projected benefit obligation and the fair value of plan assets for the years ended December 31, 2009 and 2008 (in thousands):

	2009			2008

Over (under)-funded status of the plan at end of the year	$	(5,059	)	$	(3,423	)

Accumulated Benefit Obligation	$	24,599		$	20,150

The following actuarial assumptions were used to determine the actuarial present value of our projected benefit obligation at December 31, 2009 and 2008:

	2009	2008
Weighted average assumed discount rate	5.25%	5.75%
Weighted average rate of compensation increase	3.00%	3.00%

The discount rate used to determine our projected benefit obligation at December 31, 2009 was decreased from 5.75% to 5.25%. The decrease in the discount rate was consistent with a general decrease in long-term interest rates in Europe, including The Netherlands.

Amounts recognized for the Dutch Plan in the Consolidated Balance Sheets for the years ended December 31, 2009 and 2008 consist of (in thousands):

Unrecognized net actuarial gain (loss) and foreign exchange		(5,954	)		(4,292	)
Total accumulated other comprehensive income (loss)	$	(6,536	)	$	(4,927	)

Unrecognized amounts currently recorded to Accumulated Other Comprehensive Income are expected to be recognized as components of next year's net pension benefit cost are $0.2 million of prior service cost, $0.1 million amortization of transition asset and $0.4 million of unrecognized net actuarial loss.

The components of net periodic pension cost under this plan for the years ended December 31, 2009 and 2008 included (in thousands):

	2009			2008
Service cost	$	1,084		$	1,139
Interest cost		1,386			1,342
Expected return on plan assets		(673	)		(1,218	)

Prior service cost		159			178
Unrecognized net actuarial (gain)/ loss		243			-
Net periodic pension cost	$	2,112		$	1,344

This net periodic pension cost was calculated using the following assumptions:

	2009	2008
Weighted average assumed discount rate	5.75%	5.50%
Expected long-term rate of return on plan assets	5.75%	4.25%
Weighted average rate of compensation increase	3.00%	3.00%

Plan assets at December 31, 2009 and 2008 consisted of insurance contracts with returns comparable with governmental debt securities. Our expected long-term rate of return assumptions are based on the average yield on government bonds in the Netherlands. Dutch law dictates the minimum requirements for pension funding. Our goal is to meet these minimum funding requirements, while our insurance carrier invests to minimize risks associated with future benefit payments.

Our 2010 minimum funding requirements are expected to be approximately $2.7 million. Our estimate of future annual contributions is based on current funding requirements, and we believe these contributions will be sufficient to fund the plan. Expected benefit payments under this plan for the next five years are as follows (in thousands):

2010	$	551
2011		640
2012		1,040
2013		1,143
2014		1,246
Succeeding five years		7,640

Defined Contribution Plans

We maintain four defined contribution plans (the "Defined Contribution Plans") for the benefit of eligible employees in the United States, Canada, The Netherlands and the United Kingdom. In accordance with the terms of each plan, we match the required portion of employee contributions up to specified limits and under certain plans, we may make discretionary contributions annually in accordance with the Defined Contribution Plans. For the years ended December 31, 2009, 2008 and 2007, we expensed approximately $4.9 million, $4.7 million and $4.6 million respectively, for our matching and discretionary contributions to the Defined Contribution Plans.

F-18

Deferred Compensation Arrangements

We have entered into deferred compensation contracts for certain key employees and an outside director. The benefits under these contracts are fully vested and benefits are paid when the participants attain 65 years of age. The charge to expense for officer deferred compensation in 2009, 2008 and 2007 was approximately $1.1 million, $1.3 million and $0.8 million, respectively. Life insurance policies with cash surrender values have been purchased for the purpose of funding the deferred compensation contracts.

We have adopted a non-qualified deferred compensation plan that allows certain highly compensated employees to defer a portion of their salary, commission and bonus, as well as the amount of any reductions in their deferrals under the 401(k) Plan, due to certain limitations imposed by the Internal Revenue Code of 1986, as amended. The plan also provides for employer contributions to be made on behalf of participants equal in amount to certain forfeitures of, and/or reductions in, employer contributions that participants could have received under the 401(k) Plan in the absence of certain limitations imposed by the Internal Revenue Code. Employer contributions to the deferred compensation plan were $0.2 million, $0.2 million and $0.2 million of the years ended December 31, 2009, 2008 and 2007, respectively. These employer contributions vest ratably over a period of five years.

Vesting in all employer contributions is accelerated upon the death of the participant or a change in control. Employer contributions under the plans are forfeited upon a participant's termination of employment to the extent they are not vested at that time.

The Company’s only financial assets and liabilities which involve fair value measures relate to certain aspects of the Company’s benefit plans. On a recurring basis, we use the market approach to value certain liabilities at fair value at quoted prices in an active market (Level 1) and certain assets and liabilities using significant other observable inputs (Level 2). We do not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). Gains and losses related to the fair value changes in the deferred compensation assets and liabilities are recorded in General and Administrative Expenses in the Consolidated Statement of Operations. The following table summarizes the fair value balances (in thousands):

			Fair Value Measurement at December 31, 2009
	Total		Level 1		Level 2		Level 3
Assets:
Deferred compensation plan trust assets	$	6,193	$	-	$	6,193	$	-

11. COMMITMENTS AND CONTINGENCIES

From time to time, we may be subject to legal proceedings and claims that arise in the ordinary course of business.

In 1998, we entered into employment agreements with our three senior executive officers that provided for severance benefits. The present value of the long-term liability for the benefits due upon severing the employment of these employees is approximately $4.3 million at December 31, 2009.

We do not maintain any off-balance sheet debt or other similar financing arrangements nor have we formed any special purpose entities for the purpose of maintaining off-balance sheet debt.

Operating lease commitments relate primarily to rental of equipment and office space. Rental expense for operating leases, including amounts for short-term leases with nominal future rental commitments, was approximately $14.4 million, $14.5 million and $11.5 million for the years ended December 31, 2009, 2008 and 2007, respectively.

During the first quarter of 2008, we revised our estimate of a contingent liability associated with non-income related taxes, and as a result a charge to income of $5.0 million was recorded in the Consolidated Statement of Operations to Other Expense (Income), net. The contingent liability was included in Other Long-term Liabilities in the Consolidated Balance Sheet at December 31, 2008. As a result of finalizing a settlement agreement for $2.5 million, we released the remaining $2.5 million of the contingent liability, to Other Expense (Income), net in the Consolidated Statements of Operations during the second quarter of 2009.

12. EQUITY

Equity Instruments

See Note 8, Debt and Capital Lease Obligations for additional information on the exchangeable note hedge and warrant transactions.

Treasury Shares

In connection with our initial public offering in September 1995, our shareholders authorized our Management Board to repurchase up to 10% of our issued share capital, the maximum allowed under Dutch law at the time, for a period of 18 months. This authorization was renewed at subsequent annual shareholder meetings. At a special shareholders’ meeting on January 29, 2009, following a change in Dutch law that permitted us to repurchase up to 50% of our issued share capital in open market purchases, our shareholders authorized an extension through July 29, 2010 to purchase up to 25.6% of our issued share capital, consisting of 10% of our issued share capital to be used for any legal purpose, and an additional 15.6% of our issued share capital to fulfill obligations relating to the Notes or warrants. The repurchase of shares in the open market is at the discretion of management pursuant to this shareholder authorization. From the activation of the share repurchase program on October 10, 2002 through December 31, 2009, we have repurchased 15,480,228 shares for an aggregate purchase price of approximately $633.8 million, or an average price of $40.94 per share and have cancelled 12,767,747 shares at a cost of $373.3 million. At December 31, 2009, we held 2,533,252 shares in treasury and with the authority to repurchase 3,999,857 additional shares under our stock repurchase program. The cancellation of shares has also been approved by shareholders at prior shareholder meetings. Subsequent to year end, we have repurchased 687,373 shares at a total cost of approximately $84.4 million.

In February, April, July and October 2009, we declared and paid quarterly $0.10 per share of common stock dividends. In addition to the quarterly cash dividends, a special non-recurring cash dividend of $0.75 per share of common stock was also paid on August 24, 2009. The total dividends paid in 2009 were $26.4 million. On January 14, 2010, we declared a quarterly dividend of $0.12 per share of common stock payable February 25, 2010 to shareholders of record on January 25, 2010.

13. STOCK-BASED COMPENSATION

We have granted stock options and restricted stock awards under two stock incentive plans: the 2007 Long-Term Incentive Plan (the "Plan") and the 2006 Nonemployee Director Stock Incentive Plan (the "Director Plan "). Awards under the following three compensation programs have been granted pursuant to the Plan: (1) the Executive Restricted Share Matching Program ("ESMP"), (2) the Performance Share Award Program ("PSAP") and (3) the Restricted Share Award Program ("RSAP").

F-20

2007 Long-term Incentive Plan

On April 2, 2007, the 1995 Long-Term Incentive Plan was amended, restated and renamed as the 2007 Long-Term Incentive Plan. The primary changes effected by the 2007 amendment and restatement was to (a) extend the period during which awards may be granted under the Plan to February 13, 2017, (b) require all stock options awarded under the Plan to have an exercise price per share that is at least equal to the fair market value of a common share as of the date of grant of the option (subject to adjustment under certain circumstances, such as upon a reorganization, stock split, recapitalization, or other change in our capital structure), (c) provide that stock appreciation rights may be granted under the Plan, (d) prohibit the repricing of stock options awarded under the Plan, (e) provide that no amendment to the Plan that would require shareholder approval pursuant to the requirements of the New York Stock Exchange or any exchange on which we are listed will be effective prior to approval of our shareholders, and (f) expand the performance goals enumerated under the Plan upon which restricted share awards may be based. The amendment and restatement of the Plan does not increase the number of common shares subject to the Plan. The Plan provides for a maximum of 5,400,000 common shares to be granted to eligible employees. Specifically, we encourage share ownership by awarding various long-term equity incentive awards under the Plan, consisting of the ESMP, PSAP and RSAP. We believe that widespread common share ownership by key employees is an important means of encouraging superior performance and employee retention. Additionally, our equity-based compensation programs encourage performance and retention by providing additional incentives for executives to further our growth, development and financial success over a longer time horizon by personally benefitting through the ownership of our common shares and/or rights.

Since the inception of the Plan in 1995 to 2001, we awarded stock options as the primary form of equity compensation. In 2001, we reassessed the form of award and elected to begin the use of restricted share grants which we believe are a stronger motivational tool for our employees. Restricted share awards provide some value to an employee during periods of stock market volatility, whereas stock options may have limited perceived value and may not be as affective in retaining and motivating employees when the current value of our stock is less than the option price. Currently, our long-term equity incentive compensation is exclusively in the form of restricted shares and performance restricted shares as no stock options were granted during 2009 under the Plan. At December 31, 2009, approximately 438,666 shares were available for the grant of new awards under the Plan.

2006 Nonemployee Director Stock Incentive Plan

The Director Plan provides common shares for grant to our eligible Supervisory Directors. The maximum number of shares available for award under this plan is 700,000 common shares. On June 28, 2006, the 1995 Nonemployee Director Stock Option Plan was amended, restated and renamed as the 2006 Nonemployee Director Stock Incentive Plan. The primary change effected by the 2006 amendment was to eliminate the automatic, formula grant of stock options under the prior plan and to replace that formula approach with the discretionary right of the Supervisory Board to grant stock options, restricted shares, or any combination thereof. Under the Director Plan, each nonemployee Supervisory Director is generally granted an equivalent of $100,000 in value of performance restricted shares based on the closing price of our common stock on the date of grant and will vest at the end of a three-year measurement period subject to our performance as measured against certain predetermined metrics. Only nonemployee Supervisory Directors are eligible for these equity-based awards under the Director Plan. As of December 31, 2009, approximately 291,254 shares were available for issuance under the Director Plan. Although restricted shares have been granted in 2009 pursuant to the Director Plan, no stock options were granted during 2009.

We issue shares from either treasury stock or authorized shares upon the exercise of options or lapsing of vesting restrictions on restricted stock. We have issued 27,650 shares and 78,150 shares out of treasury stock relating to the exercise of stock options and the vesting of restricted stock, respectively. We do not use cash to settle equity instruments issued under stock-based compensation awards.

Executive Restricted Share Matching Program

The ESMP was implemented in June 2002 to encourage personal investment in our common stock by our executive officers. Under the program, we matched on a one-for-one basis each share that an executive purchased on the open market or held in his deferred compensation, 401(k) or other retirement account as of June 1, 2002, up to a maximum of 50,000 shares per participant.

Pursuant to the ESMP, on June 1, 2005, we issued an additional 76,200 restricted shares (the "Restricted Gross-up Shares") in the aggregate to reimburse the participants for tax liabilities resulting from the vesting of the original grant of 132,853 restricted shares under the ESMP and their eventual vesting in the Restricted Gross-up Shares. Historically, we had accounted for the Restricted Gross-up Shares as a variable award and remeasured it at each balance sheet date. Upon adoption of revised accounting standards in 2006, the Restricted Gross-up Shares were classified as an equity award resulting in the fair value being fixed at the original grant-date fair value. Compensation expense was recorded over the vesting period based on the estimated number of shares that management

F-21

believed would ultimately vest. The Restricted Gross-up Shares vested on June 1, 2007. During the year ended December 31, 2007, we recorded $0.4 million of compensation expense for the Restricted Gross-up Shares. The total fair value which is the intrinsic value of the shares vested was $7.0 million in 2007. We have recognized a tax benefit from the vesting of the ESMP of $0.3 million in 2008.

Performance Share Award Program

Awards Under the Plan

Under the PSAP, certain executives were awarded rights to receive a pre-determined number of common shares if our calculated return on equity ("ROE"), as defined in the PSAP, equals or exceeds a pre-determined target ROE on the measurement date of December 31, 2007, which is the last day of the applicable three year performance period. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance targets are not met as of the last day of the respective performance periods. Under this arrangement we have granted rights relating to an aggregate of 120,000 shares in 2005. In February 2008, the Equity Awards Subcommittee of our Compensation Committee of our Board of Supervisory Directors determined that the performance target criteria had been met relating to rights to an aggregate of 118,000 shares. We issued these 118,000 common shares on February 12, 2008 and, simultaneously, the participants surrendered 40,736 common shares to settle any personal tax liabilities which may result from the award, as permitted by the agreement. We recorded these surrendered shares as treasury stock with an aggregate cost of $4.5 million, at $111.26 per share. We recognized compensation expense of $0.9 million in 2007. We have recognized a tax benefit from the vesting of the PSAP of $7.8 million in 2008.

Awards Under the Director Plan

On September 15, 2006, we awarded rights relating to an aggregate of 12,000 PSAP shares under the Director Plan to our nonemployee Supervisory Directors for which the performance period began on September 15, 2006 and ended on September 15, 2009. The performance target for this award is based on a calculated ROE, as defined in the agreement, with full vesting occurring if our ROE equals or exceeds the pre-determined target ROE of 35% at the end of the three-year performance period. In September 2009, it was determined that the performance target criteria had been met relating to rights to an aggregate of 12,000 shares. We issued these 12,000 common shares on September 15, 2009 and, simultaneously, the participants surrendered 2,093 common shares to settle any personal tax liabilities which may result from the award, as permitted by the agreement. We recorded these surrendered shares as treasury stock with an aggregate cost of $0.2 million, at $101.96 per share. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $0.8 million over a three-year period that began on September 15, 2006, of which, $0.2 million, $0.3 million, and $0.3 million was recognized in 2009, 2008, and 2007, respectively.

On August 15, 2007, we awarded rights relating to an aggregate of 12,000 PSAP shares under the Director Plan to our nonemployee Supervisory Directors for which the performance period began on August 15, 2007 and ends on August 15, 2010. The performance target for this award is based on a calculated ROE, as defined in the agreement, with full vesting occurring if our ROE equals or exceeds the pre-determined target ROE of 50% at the end of the three-year performance period. If our ROE for the performance period does not meet the target ROE but equals or exceeds 40%, then the number of shares to be issued would be interpolated based on the terms of the agreement. This arrangement is recorded as an equity award that requires us to recognize compensation expense based on the probability of the performance target being achieved. Compensation expense totaling $1.2 million will be recognized over a three-year period that began on August 15, 2007, of which, $0.4 million, $0.4 million, and $0.2 million has been recognized in 2009, 2008, and 2007, respectively. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 8 months.

On July 15, 2008, we awarded rights relating to an aggregate of 4,452 PSAP shares under the Director Plan to our nonemployee Supervisory Directors for which the performance period began on July 15, 2008 and ends on July 15, 2011. The performance target for this award is based on a calculated ROE, as defined in the agreement, with full vesting occurring if our ROE equals or exceeds the pre-determined target ROE of 200% at the end of the three-year performance period. If our ROE for the performance period does not meet the target ROE but equals or exceeds 160%, then the number of shares to be issued would be interpolated based on the terms of the agreement. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $0.6 million over a three-year period that began on July 15, 2008, of which, $0.2 million and $0.1 million has been recognized in 2009 and 2008, respectively. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 19 months.

On July 15, 2009, we awarded rights relating to an aggregate of 6,942 PSAP shares under the Director Plan to our nonemployee Supervisory Directors for which the performance period began on July 15, 2009 and ends on July 15, 2012. The performance target for this award is based on a calculated ROE, as defined in the agreement, with full vesting occurring if our ROE equals or exceeds the returns earned by members of the S&P 500 Oil & Gas Equipment & Services index, with 50% of the shares vesting if our return is at or above the 50th percentile of the members’ return and 100% of the shares vesting if our return is at or above the 75th percentile of the

members’ return. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $0.6 million over a three-year period that began on July 15, 2009, of which, $0.1 million as been recognized in 2009. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 31 months.

Restricted Share Award Program

In 2004, the Equity Awards Subcommittee of our Compensation Committee of our Board of Supervisory Directors approved the RSAP to continue to attract and retain the best employees, and to better align employee interests with those of our shareholders. Under this arrangement we have granted 123,550 shares in 2009. The shares issued in 2009 have a six year ratable vesting schedule where 1/6th of the grant vests on each following anniversary date. No performance accelerators for early vesting exist for these awards. Awards under the RSAP are classified as an equity award and recorded at the grant-date fair value and the compensation expense is being recognized over the expected life of the award. As of December 31, 2009, there was $21.7 million of unrecognized total stock-based compensation relating to nonvested RSAP awards. The unrecognized compensation expense is expected to be recognized over an estimated weighted-average amortization period of 46 months. The weighted-average grant-date fair value of shares granted was $10.8 million, $15.2 million and $5.9 million in 2009, 2008 and 2007, respectively and we have recognized compensation expense of $5.0 million, $3.9 million and $3.0 million in 2009, 2008 and 2007, respectively. The total fair value which is the intrinsic value of the shares vested was $5.7 million, $3.1 million and $3.3 million in 2009, 2008 and 2007, respectively. We have recognized a tax benefit from the vesting of the RSAP of $0.2 million, $1.5 million and $0.2 million in 2009, 2008 and 2007, respectively.

Nonvested restricted share awards as of December 31, 2009 and changes during the year were as follows:

During the later part of 2008, the USD strengthened significantly against most other currencies across the globe. As a result, we experienced unusually high losses in foreign currency translation for the fourth quarter of 2008. In 2009, most foreign currencies partially recovered some of the value lost in 2008 against the USD and as a result we experienced foreign currency translation gains. However, virtually all the foreign currency gains experienced in 2009 were offset by our foreign currency losses related to Venezuela.

In 2008, we revised our estimate of a contingent liability associated with non-income related taxes, and as a result, a charge to income of $5.0 million was recorded in the Consolidated Statements of Operations to Other Expense (Income), net. The contingent liability is included in Other Long-term Liabilities in the Consolidated Balance Sheet at December 31, 2008. As a result of finalizing a settlement agreement for $2.5 million, we released the remaining $2.5 million of the contingent liability during the second quarter of 2009.

In 2008, we recorded a gain of $1.1 million in connection with the sale of a small office building.

Foreign Currency Risk

We operate in a number of international areas which exposes us to foreign currency exchange rate risk. We do not currently hold or issue forward exchange contracts or other derivative instruments for hedging or speculative purposes. (A foreign exchange contract is an agreement to exchange different currencies at a given date and at a specified rate.) Foreign exchange gains and losses are the result of fluctuations in the USD against foreign currencies and are included in other expense (income) in the statements of operations. We recognized foreign exchange losses in countries where the USD weakened against the local currency and we had net monetary liabilities denominated in the local currency; as well as countries where the USD strengthened against the local currency and we had net monetary assets denominated in the local currency. We recognized foreign exchange gains in countries where the USD strengthened against the local currency and we had net monetary liabilities denominated in the local currency and in countries where the USD weakened against the local currency and we had net monetary assets denominated in the local currency. Foreign exchange gains and losses are summarized in the following table (in thousands):

As a result of the political and financial instability in Venezuela, the Bolivar ("VEB") declined in value relative to other currencies. In January 2010, the Venezuelan government announced that the fixed official exchange rate would be changed to a dual system that includes a rate of 2.6 VEB per USD for food and heavy machine importers and a rate of 4.3 VEB per USD for all others from 2.15 VEB per USD. However, the freely traded or parallel market valued the exchange rate at approximately 5 VEB per USD at year end. Management determined the parallel market rate is the most appropriate rate to use for remeasuring the financial statements. Using the parallel market rate we recognized a devaluation of our net monetary assets resulting in a foreign exchange loss of approximately $1.3 million in the fourth quarter of 2009. At December 31, 2009, our net monetary assets denominated in VEB in Venezuela were $1.2 million. We continue to de-emphasize our operations and financial position in this country.

15. SEGMENT REPORTING

We operate our business in three reportable segments: (1) Reservoir Description, (2) Production Enhancement and (3) Reservoir Management. These business segments provide different services and utilize different technologies.

-	Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.

-	Production Enhancement: Includes products and services relating to reservoir well completions, perforations, stimulations and production. We provide integrated services to evaluate the effectiveness of well completions and to develop solutions aimed at increasing the effectiveness of enhanced oil recovery projects.

-	Reservoir Management: Combines and integrates information from reservoir description and production enhancement services to increase production and improve recovery of oil and gas from our clients' reservoirs.

Results for these business segments are presented below. We use the same accounting policies to prepare our business segment results as are used to prepare our Consolidated Financial Statements. We evaluate performance based on income or loss before income tax, interest and other non-operating income (expense). Summarized financial information concerning our segments is shown in the following table (in thousands):

17. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2009, the FASB issued the FASB Accounting Standards Codification (“ASC”). The Codification has become the single source for all authoritative GAAP recognized by the FASB to be applied for financial statements issued for periods ending after September 15, 2009. We applied the Codification to our Annual Report on Form 10-K for the period ending December 31, 2009. The Codification does not change GAAP and did not have an effect on our financial position or results of operations.
