NOTES TO THE UNAUDITED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1.  BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Core Laboratories N.V. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information and footnote disclosures required by U.S. GAAP and should be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011 (the "2011 Annual Report").

Core Laboratories N.V. uses the equity method of accounting for investments in which it has less than a majority interest and over which it does not exercise control. Non-controlling interests have been recorded to reflect outside ownership attributable to consolidated subsidiaries that are less than 100% owned.  In the opinion of management, all adjustments considered necessary for the periods presented have been included in these financial statements.  Furthermore, the operating results presented for the three and nine months ended September 30, 2012 may not necessarily be indicative of the results that may be expected for the year ended December 31, 2012.

Core Laboratories N.V.'s balance sheet information for the year ended December 31, 2011 was derived from the 2011 audited consolidated financial statements but does not include all disclosures in accordance with U.S. GAAP.

Certain reclassifications were made to prior period amounts in order to conform to the current period presentation.  These reclassifications had no impact on the reported net income for the three and nine month periods ended September 30, 2011.

Additionally, revision adjustments were made between Services Revenue and Product Sales Revenue and between Cost of Services and Cost of Product Sales in the Consolidated Statements of Operations for 2011 which did not affect total revenues, operating income or net income for the period.

References to "Core Lab", "we", "our" and similar phrases are used throughout this Quarterly Report on Form 10-Q and relate collectively to Core Laboratories N.V. and its consolidated subsidiaries.

2.  INVENTORIES

Inventories consist of the following (in thousands):

	September 30, 2012		December 31, 2011
	(Unaudited)
Finished goods	$	39,875	$	32,604
Parts and materials	12,030		18,004
Work in progress	1,902		2,606
Total inventories	$	53,807	$	53,214

We include freight costs incurred for shipping inventory to customers in the Cost of product sales line of the Consolidated Statements of Operations.

3. GOODWILL AND INTANGIBLES

We account for intangible assets with indefinite lives, including goodwill, in accordance with the applicable accounting guidance, which requires us to evaluate these assets for impairment annually, or more frequently if an indication of impairment has occurred.  Based upon our most recent evaluation, we determined that goodwill is not impaired.  We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives.

In 2011, we acquired a business providing additional manufacturing capacity for our Canadian operations for $18.8 million in cash. We have accounted for this acquisition by allocating the purchase price to the net assets acquired based on their estimated fair values at the date of acquisition, resulting in an increase to goodwill of $8.6 million and an increase of $0.5

6

million in intangible assets. In 2012, a post-closing adjustment was recorded that increased the purchase price and goodwill by $0.6 million. The acquisition was recorded in the Production Enhancement business segment.

4.  DEBT AND CAPITAL LEASE OBLIGATIONS

Debt is summarized in the following table (in thousands):

	September 30, 2012		December 31, 2011
	(Unaudited)
Senior notes	150,000		150,000
Credit facility	63,000		73,000
Capital lease obligations	89		132
Financing of corporate insurance	—		2,287
Total debt	213,089		225,419
Less - current maturities of long-term debt and capital lease obligations	45		2,344
Long-term debt and capital lease obligations, net	$	213,044	$	223,075

In 2011, we issued two series of senior notes with an aggregate principal amount of $150 million ("Senior Notes") in a private placement transaction. Series A consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.01% and are due in full on September 30, 2021. Series B consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.11% and are due in full on September 30, 2023. Interest on each series of the Senior Notes is payable semi-annually on March 30 and September 30.

We maintain a credit facility (the "Credit Facility") with an aggregate borrowing capacity of $300 million at September 30, 2012. The Credit Facility provides an option to increase the commitment under the Credit Facility to $350 million, if certain conditions are met.  The Credit Facility bears interest at variable rates from LIBOR plus 1.50% to a maximum of LIBOR plus 2.25%.  Any outstanding balance under the Credit Facility is due September 28, 2016 when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity at any point in time is reduced by borrowings outstanding at the time and outstanding letters of credit which totaled $17.0 million at September 30, 2012, resulting in an available borrowing capacity under the Credit Facility of $220.0 million.  In addition to those items under the Credit Facility, we had $26.4 million of outstanding letters of credit and performance guarantees and bonds from other sources as of September 30, 2012.

The terms of the Credit Facility and the Senior Notes require us to meet certain financial and operational 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 agreements. Certain of our material, wholly-owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes.

The estimated fair value of total debt at September 30, 2012 and December 31, 2011 approximated the book value of total debt. The fair value was estimated using Level 2 inputs including rates on similar debt recently issued by our peer group.

5.  PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees (the "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. The benefits earned by the employees are immediately vested.  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 expire after five years at which time they are replaced with new contracts that are adjusted to include changes in the benefit obligation for the current year and redemption of the expired contracts.  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 to the insurance company based on each employee's age and current salary.

The following table summarizes the components of net periodic pension cost under this plan for the three and nine months ended September 30, 2012 and 2011 (in thousands):

	Three Months Ended						Nine Months Ended

Amortization of net loss	—			84			—			252
Net periodic pension cost	$	408		$	676		$	1,259		$	2,041

During the nine months ended September 30, 2012, we contributed approximately $1.6 million, as determined by the insurance company, to fund the estimated 2012 premiums on investment contracts held by the Dutch Plan.

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 deferred compensation plan for employees in the United States (the "Deferred Compensation Plan"), due to certain limitations imposed by the U.S. Internal Revenue Code of 1986, as amended (the "Internal Revenue Code").  The Deferred Compensation 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 vest ratably over a period of five years. Contributions to the plan are invested in equity and other investment fund assets within life insurance policies, and carried on the balance sheet at fair value. A participant's plan benefits include the participant's deferrals, the vested portion of the employer's contributions, and deemed investment gains and losses on such amounts. The benefits under these contracts are fully vested and payment of benefits generally commences as of the last day of the month following the termination of services except that the payment of benefits for select executives generally commences on the first working day following a six month waiting period following the date of termination.

On a recurring basis, we use the market approach to value certain assets and 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) with the assistance of a third party specialist. 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 Statements of Operations.  The following table summarizes the fair value balances (in thousands):

6. COMMITMENTS AND CONTINGENCIES

8

We have been and may from time to time be named as a defendant in legal actions that arise in the ordinary course of business.  These include, but are not limited to, employment-related claims and contractual disputes or claims for personal injury or property damage which occur in connection with the provision of our products and services.  Management does not currently believe that any of our pending contractual, employment-related, personal injury or property damage claims and disputes will have a material effect on our future results of operations, financial position or cash flow.

7.  EQUITY

During the three months ended September 30, 2012, we repurchased 283,513 of our common shares for $33.2 million. Included in this total were rights to 3,513 shares valued at $0.4 million that were surrendered to us pursuant to the terms of a stock-based compensation plan in consideration of the participants' tax burdens that may result from the issuance of common shares under that plan. During the nine months ended September 30, 2012, we repurchased 686,896 of our common shares for $83.4 million. Included in this total were rights to 42,103 shares valued at $5.3 million that were surrendered to us pursuant to the terms of a stock-based compensation plan in consideration of the participants' tax burdens that may result from the issuance of common shares under that plan. Such common shares, unless canceled, may be reissued for a variety of purposes such as future acquisitions, non-employee director stock awards or employee stock awards.

At the annual meeting of shareholders on May 16, 2012, the shareholders approved the cancellation of 1,138,224 shares of our common stock then held as treasury stock. These treasury shares were cancelled on August 1, 2012, after the expiration of the waiting period required under Dutch law. In accordance with ASC 505-30-30-8, we charge the excess of the cost of the treasury stock over its par value to additional paid-in capital. If additional paid-in capital is not sufficient for this charge, the remainder is charged directly to retained earnings.

In February, May, and August 2012, we paid a quarterly dividend of $0.28 per share of common stock.  In addition, on October 9, 2012, we declared a quarterly dividend of $0.28 per share of common stock for shareholders of record on October 19, 2012 and payable on November 20, 2012.

The following table summarizes our changes in equity for the nine months ended September 30, 2012 (in thousands):

8.  EARNINGS PER SHARE

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares 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):

	Three Months Ended		Nine Months Ended
	September 30,		September 30,
	2012	2011	2012	2011
	(Unaudited)		(Unaudited)
Weighted average basic common shares outstanding	47,232	46,606	47,436	45,930
Effect of dilutive securities:
Stock options	11	12	12	20
Contingent shares	136	80	128	69
Restricted stock and other	149	249	178	266
Senior exchangeable notes	—	1,083	—	1,144
Warrants	—	—	—	1,205
Weighted average diluted common and potential common shares outstanding	47,528	48,030	47,754	48,634

In 2006, we issued $300 million aggregate principal amount of Senior Exchangeable Notes (the "Exchangeable Notes") which were exchangeable into shares of Core Laboratories N.V. common stock under certain circumstances. Included in the table above are 1,083,000 shares which were added to the share count for the three months ended September 30, 2011, and 1,144,000 shares which were added to the share count for the nine months ended September 30, 2011.  These shares were included in calculating the impact to our dilutive earnings per share for the three and nine months ended September 30, 2011. All of the Exchangeable Notes were exchanged or reached maturity in 2011.

In 2006, we sold warrants that gave the holders the right to acquire our common shares. Included in the table above are 1,205,000 shares which were added to the share count for the nine months ended September 30, 2011, because the average share price exceeded the strike price of the warrants.  These shares were included in calculating the impact to our dilutive earnings per share for the nine months ended September 30, 2011. The warrants were fully settled in 2011.

During the second quarter of 2012, we incurred legal, accounting and other fees in connection with the realignment of certain of our legal entities into a more cost effective structure and the listing of our shares on the NYSE Euronext Amsterdam Stock Exchange.

As a result of a supply disruption in 2011 from a key vendor that provided certain high performance specialty steel tubulars used with the Company's perforating systems, we filed a claim under our business interruption insurance policy which was fully settled during 2012 for $4.4 million. We recorded a gain of $3.4 million in the first quarter of 2012 for the initial payment and a gain of $1.0 million in the third quarter of 2012 when the claim was settled and closed.

As a result of reaching a settlement on a fire damage claim we filed in 2010, we recorded insurance recovery gains of $0.1 million and $0.8 million for the nine months ended September 30, 2012 and 2011.

Foreign exchange (gain) loss by currency is summarized in the following table (in thousands):

10.  INCOME TAX EXPENSE

The effective tax rates for the three months ended September 30, 2012 and 2011 were 25.5% and 24.5%, respectively.  The effective tax rates for the year-to-date 2012 and 2011 were 24.9% and 21.9%, respectively.  

Included in the nine months ended September 30, 2011 is the reversal of $10.4 million in tax liabilities provided over the period of 2007-2010 as a result of audits of prior year returns offset by $6.0 million in other discrete items. The change in income tax expense also reflects the change in activity levels among jurisdictions with different tax rates.

11.  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.

11

• 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). All interest and other non-operating income (expense) is attributable to the Corporate & Other area and is not allocated to specific business segments. Summarized financial information concerning our segments is shown in the following table (in thousands):

12. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued ASU 2011-04 relating to fair value measurement (FASB ASC Topic 820), which amends current guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International

12

Financial Reporting Standards. The amendments generally represent clarification of FASB ASC Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05 which provides new guidance on the presentation of comprehensive income (FASB ASC Topic 220) in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The provisions for this pronouncement are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In September 2011, the FASB issued ASU 2011-08 relating to testing goodwill for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test goodwill for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In December 2011, the FASB issued ASU 2011-12, which defers changes in Update 2011-05 that relate to the presentation of reclassification of adjustments for entities that report items of other comprehensive income. This pronouncement is effective at the same time as ASU 2011-05 for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In July 2012, the FASB issued ASU 012-02, relating to testing intangible assets and long-lived assets for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test indefinite-lived intangible assets for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning September 15, 2012. The adoption of this pronouncement will not have a material effect on our consolidated financial statements.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion summarizes the financial position of Core Laboratories N.V. and its subsidiaries as of September 30, 2012 and should be read in conjunction with (i) the unaudited consolidated interim financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q and (ii) the consolidated financial statements and accompanying notes to our Annual Report on Form 10-K for the fiscal year ended December 31, 2011 (the "2011 Annual Report").

General

Core Laboratories N.V. is a Netherlands limited liability company.  It was established in 1936 and is 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.  These products and services can enable our clients to improve reservoir performance and increase oil and gas recovery from their producing fields.  Core Laboratories N.V. has over 70 offices in more than 50 countries and employs approximately 5,000 people worldwide.

References to "Core Lab", "we", "our" and similar phrases are used throughout this Quarterly Report on Form 10-Q and relate collectively to Core Laboratories N.V. and its consolidated affiliates.

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.

• 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.

Cautionary Statement Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Certain statements contained in this Management's Discussion and Analysis of Financial Condition and Results of Operations section, including those under the headings "Outlook" and "Liquidity and Capital Resources", and in other parts of this Form 10-Q, are forward-looking. In addition, from time to time, we may publish forward-looking statements relating to such matters as anticipated financial performance, business prospects, technological developments, new products, research and development activities and similar matters. Forward-looking statements can be identified by the use of forward-looking terminology such as "may", "will", "believe", "expect", "anticipate", "estimate", "continue", or other similar words, including statements as to the intent, belief, or current expectations of our directors, officers, and management with respect to our future operations, performance, or positions or which contain other forward-looking information. These forward-looking statements are based on our current expectations and beliefs concerning future developments and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, no assurances can be given that the future results indicated, whether expressed or implied, will be achieved. While we believe that these statements are and will be accurate, our actual results and experience may differ materially from the anticipated results or other expectations expressed in our statements due to a variety of risks and uncertainties.

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 are summarized as:

14

•general and economic business conditions;

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

•cost of producing and the ability to deliver 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 or geologic/geophysical conditions;

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

•civil unrest or political uncertainty in oil producing or consuming countries;

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

•changes in existing laws, regulations, or other governmental actions;

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

•availability of services and materials for our clients to grow their capital expenditures; and

•availability of materials and equipment from key suppliers

•cyber attacks on our network that disrupt operations or result in lost critical data.

Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For a more detailed discussion of some of the foregoing risks and uncertainties, see "Item 1A - Risk Factors" in our 2011 Annual Report and in Part II of this document, as well as the other reports filed by us with the Securities and Exchange Commission (“SEC”).

Outlook

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

We have established internal earnings targets that are based on market conditions existing at the time our targets were established.  Based on recent activity levels, we believe that the current level of activities, workflows, and operating margins within North America will remain similar to third quarter levels, while international activity continues moderate increases during the remainder of 2012.

Services revenue increased to $174.5 million for the third quarter of 2012, up 9% when compared to $160.5 million for the third quarter of 2011.  For the nine months ended September 30, 2012, services revenue increased to $512.9 million, up 12% when compared to $458.9 million for the same period of 2011.  The increase in services revenue was primarily due to our continued focus on worldwide crude-oil related and large natural gas for liquefaction projects, especially those related to the development of deepwater fields offshore West and East Africa, the eastern Mediterranean, and the Gulf of Mexico.

Product Sales Revenue

Revenue associated with product sales was up slightly to $71.0 million for the third quarter of 2012, compared to $70.8 million for the third quarter of 2011. For the nine months ended September 30, 2012, product sales revenues increased to $213.7 million, up 4% from $205.0 million for the same period of 2011 despite declining drilling activity in North America. Land rig count declined by 6% in the U.S. during the third quarter of 2012 while the Canadian rig count is 30% below prior year levels.

Cost of Services

Cost of services expressed as a percentage of services revenue was 59% for the quarter ended September 30, 2012, an improvement from 62% in the same period in 2011. For the nine months ended September 30, 2012, cost of services expressed as a percentage of services revenue was 59%, an improvement when compared to 64% in the same period in 2011. The margin improvement is a result of higher sales, including a better mix of projects aimed at more complex reservoirs, over the fixed cost structure.

Cost of Product Sales

17

Cost of product sales expressed as a percentage of product sales revenue was 74% for the quarter ended September 30, 2012, up from 71% during the same period in 2011. For the nine months ended September 30, 2012, cost of product sales expressed as a percentage of product sales revenue was 73%, up from 70% during the same period in 2011. The cost of raw materials, especially specialty steel, increased substantially in the second half of 2011 which increased our cost of sales in 2012 as these raw materials are converted to finished goods and sold.

General and Administrative Expenses

General and administrative expenses include corporate management and centralized administrative services that benefit our operations. General and administrative expenses were $10.5 million for the third quarter of 2012, which represents 4% of revenue, a decrease from the third quarter of 2011 when general and administrative expenses represented 5% of revenue. For the nine months ended September 30, 2012, general and administrative expenses were $30.9 million, which represents 4% of revenue, a decrease from 5% of revenue for the same period of 2011.

Depreciation and Amortization Expense

Depreciation and amortization expense was $6.5 million for the third quarter of 2012 compared to $5.7 million in the third quarter of 2011, reflecting the timing of capital expenditures in 2012. For the nine months ended September 30, 2012, depreciation and amortization expense was $17.4 million compared to $17.4 million in the same period of 2011.

During the second quarter of 2012, we incurred legal, accounting and other fees in connection with the realignment of certain of our legal entities into a more cost effective structure and the listing of our shares on the NYSE Euronext Amsterdam Stock Exchange.

As a result of a supply disruption in 2011 from a key vendor that provided certain high performance specialty steel tubulars used with the Company's perforating systems, we filed a claim under our business interruption insurance policy which was fully settled during 2012 for $4.4 million. We recorded a gain of $3.4 million in the first quarter of 2012 for the initial payment and a gain of $1.0 million in the third quarter of 2012 when the claim was settled and closed.

As a result of reaching a settlement on a fire damage claim we filed in 2010, we recorded insurance recovery gains of $0.1 million and $0.8 million for the nine months ended September 30, 2012 and 2011, respectively.

Foreign exchange (gain) loss by currency is summarized in the following table (in thousands):

Interest Expense

Interest expense for the three months ended September 30, 2012 and 2011 was $2.2 million and $3.8 million, respectively.  Interest expense for the nine months ended September 30, 2012 and 2011 was $6.5 million and $8.7 million, respectively. 

Our Exchangeable Notes were fully repaid during the fourth quarter of 2011 and were replaced by our $150 million Senior Notes (the "Senior Notes") which carry a lower interest expense.

Income Tax Expense

The effective tax rates for the three months ended September 30, 2012 and 2011 were 25.5% and 24.5%, respectively.  The effective tax rates for the nine months ended September 30, 2012 and 2011 were 24.9% and 21.9%, respectively.  

Included in the three and nine months ended September 30, 2011 is the reversal of $10.4 million in tax liabilities provided over the period of 2007-2010 as a result of audits of prior year returns offset by $6.0 million in other discrete items. The change in income tax expense also reflects the change in activity levels among jurisdictions with different tax rates.

Segment Analysis

Our operations are managed primarily in three complementary segments - Reservoir Description, Production Enhancement and Reservoir Management.  The following tables summarize our results by operating segment for the three and nine months ended September 30, 2012 and 2011 (in thousands):

Reservoir Description

Revenue from the Reservoir Description segment increased 4%, or $4.3 million, to $124.2 million in the third quarter of 2012, compared to $119.9 million in the third quarter of 2011.  For the nine months ended September 30, 2012, revenues increased 6%, or $20.5 million, to $366.7 million, compared to $346.2 million in the same period of 2011.  This segment’s operations, which focus on international crude-oil related products, continued to benefit from increased activity in large-scale core analyses and reservoir fluids characterization studies in the Asia-Pacific areas, offshore West and East Africa, the Eastern Mediterranean region and the Middle East, including Iraq, Kuwait, and the United Arab Emirates.

Operating income in the third quarter of 2012 increased by 28%, or $8.0 million, to $36.8 million compared to $28.8 million for the third quarter of 2011.  Operating income for the nine months ended September 30, 2012 increased by 31%, or $25.4 million, to $107.3 million compared to $81.8 million for the same period of 2011.  Operating margin for the quarter ended September 30, 2012 was 30%, compared to 24% for the same period in 2011. This increase is a result of higher sales, including a better mix of projects aimed at more complex reservoirs, over the fixed cost structure.

Production Enhancement

Revenue from the Production Enhancement segment increased by 4%, or $3.5 million, to $100.9 million in the third quarter of 2012 compared to $97.4 million in the third quarter of 2011. Revenues increased by 11%, or $28.9 million, to $297.2 million for the nine months ended September 30, 2012, compared to $268.3 million in the same period of 2011. The revenue increase was primarily due to demand for our stimulation diagnostic services both for fracture diagnostics in North America and flood diagnostics internationally.

Operating income in the third quarter of 2012 increased by 5%, or $1.6 million, to $32.3 million from $30.7 million for the third quarter of 2011.  For the nine months ended September 30, 2012, operating income increased by 22%, to $95.4 million over the same period of 2011.  Operating margins remained constant at 32% in the third quarter of 2012 compared to the same period in 2011.  The increase in operating income from 2011 to 2012 was primarily driven by increased demand for the company's proprietary and patented hydraulic fracture and field-flood diagnostic technologies such as SpectraChem™, ZeroWash™, and SpectraFlood™ tracers in North America and internationally.

Reservoir Management

Revenue from the Reservoir Management segment increased by 45% to $20.4 million in the third quarter of 2012 compared to $14.1 million for the third quarter of 2011.  Revenues for the nine months ended September 30, 2012 increased by 27% to $62.8 million compared to $49.3 million for the same period of 2011.  The increase in revenue was due to ongoing interest in several of our existing multi-client reservoir studies such as the Duvernay Shale Project in Canada and the Tight Oil Reservoirs of the Midland Basin study.

Operating income in the third quarter of 2012 increased 72% to $6.0 million from $3.5 million for the third quarter of 2011.

20

For the nine months ended September 30, 2012, operating income was $21.1 million compared to $17.5 million for the same period of 2011. Operating margins increased to 30% in the third quarter of 2012 compared to 25% for the same period in 2011. The higher margin in the third quarter of 2012 was primarily a result of increased revenue over a predominantly fixed cost structure.

Liquidity and Capital Resources

General

We have historically financed our activities through cash on hand, cash flows from operations, bank credit facilities, or the issuance of debt and equity financing.

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 (which is the most directly comparable GAAP measure) less cash paid for capital expenditures.  Management believes that free cash flow provides useful information to investors regarding the cash that was available in the period that was in excess of our needs to fund our capital expenditures and operating activities. Free cash flow is not a measure of operating performance under GAAP, and should not be considered in isolation nor construed as an alternative to operating profit, net income (loss) or cash flows from operating, investing or financing activities, each as determined in accordance with GAAP. Free cash flow does not represent residual cash available for distribution because we may have other non-discretionary expenditures that are not deducted from the measure. Moreover, since free cash flow is not a measure determined in accordance with GAAP and thus is susceptible to varying interpretations and calculations, free cash flow as presented, may not be comparable to similarly titled measures presented by other companies.  The following table reconciles this non-GAAP financial measure to the most directly comparable measure calculated and presented in accordance with GAAP for the nine months ended September 30, 2012 and 2011 (in thousands):

	Nine Months Ended September 30,				% Change
	2012		2011		2012/2011
Free cash flow calculation:	(Unaudited)
Net cash provided by operating activities	$	152,150	$	146,829	4	%
Less:  cash paid for capital expenditures	24,154		18,203		33	%
Free cash flow	$	127,996	$	128,626	—	%

Free cash flow for the first nine months of 2012 was unchanged when compared to the same period in 2011 as the increase in net income for the period was offset by decreases in current and long-term liabilities. In addition, capital expenditures were higher in the first nine months of 2012 compared to the same period in 2011.

Cash Flows

The following table summarizes cash flows for the nine months ended September 30, 2012 and 2011 (in thousands):

	Nine Months Ended September 30,						% Change
	2012			2011			2012/2011
Cash provided by/(used in):	(Unaudited)
Operating activities	$	152,150		$	146,829		4	%
Investing activities	(24,745		)	(39,474		)	(37	)%
Financing activities	(132,079		)	(224,214		)	(41	)%
Net change in cash and cash equivalents	$	(4,674	)	$	(116,859	)	(96	)%

The increase in cash flows from operating activities for the first nine months of 2012 compared to the same period in 2011 was primarily attributable to increased net income offset by increases in current assets and decreases in current liabilities.

Cash flows used in investing activities were lower during 2012 when compared to 2011 primarily due to the $21 million acquisition in 2011, offset by an increase in capital expenditures of $24.2 million up from $18.2 million for the nine month periods ended September 30, 2012 and 2011, respectively.

21

The decrease in cash flows used in financing activities for the first nine months of 2012 when compared to the same period in 2011 was due to decreases of $219.5 million in the amount used for settlement of warrants and $95.9 million in the amount of net debt reduction offset by an increase of $27.9 million in the amount paid for the repurchase of our common shares. In the first nine months of 2011, we settled warrants in the amount of $219.5 million. All of these warrants were settled during 2011. During the first nine months of 2012, we repurchased 686,896 shares for an aggregate price of $83.4 million compared to 604,972 shares for an aggregate price of $55.5 million during the same period in 2011. In the first nine months of 2012, we used $12.3 million of cash to reduce our net debt, as compared to receiving $83.5 million of cash during the first nine months of 2011 as a result of issuing the Senior Notes and increasing the drawings on our Credit Facility offset by the settlement of the Exchangeable Notes.  

Notes, Credit Facilities and Available Future Liquidity

In September 2011, we issued two series of senior notes with an aggregate principal amount of $150 million ("Senior Notes") in a private placement transaction. Series A consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.01% and are due in full on September 30, 2021. Series B consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.11% and are due in full on September 30, 2023. Interest on each series of the Senior Notes is payable semi-annually on March 30 and September 30.

We maintain a credit facility (the "Credit Facility") with an aggregate borrowing capacity of $300 million at September 30, 2012. The Credit Facility provides an option to increase the commitment under the Credit Facility to $350 million, if certain conditions are met.  The Credit Facility bears interest at variable rates from LIBOR plus 1.50% to a maximum of LIBOR plus 2.25%.  Any outstanding balance under the Credit Facility is due September 28, 2016 when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under the Credit Facility. Our available capacity at any point in time is reduced by borrowings outstanding at the time and outstanding letters of credit which totaled $17.0 million at September 30, 2012, resulting in an available borrowing capacity under the Credit Facility of $220.0 million.  In addition to those items under the Credit Facility, we had $26.4 million of outstanding letters of credit and performance guarantees and bonds from other sources as of September 30, 2012.

The terms of the Credit Facility and the Senior Notes require us to meet certain financial and operational 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 agreements. Certain of our material, wholly-owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes.

Our ability to maintain and grow our operating income and cash flow depends, to a large extent, on continued investing activities. We are a Netherlands holding company and substantially all of our operations are conducted through subsidiaries. Consequently, our cash flow depends upon the ability of our subsidiaries to pay cash dividends or otherwise distribute or advance funds to us.  We believe our future cash flows from operations, supplemented by our borrowing capacity and issuances of additional equity, should be sufficient to fund our debt requirements, capital expenditures, working capital, dividend payments and future acquisitions.

Recent Accounting Pronouncements

In May 2011, the FASB issued ASU 2011-04 relating to fair value measurement (FASB ASC Topic 820), which amends current guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. The amendments generally represent clarification of FASB ASC Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05 which provides new guidance on the presentation of comprehensive income (FASB ASC Topic 220) in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The provisions for this pronouncement are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this pronouncement for our fiscal year beginning January

22

1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In September 2011, the FASB issued ASU 2011-08 relating to testing goodwill for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test goodwill for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In December 2011, the FASB issued ASU 2011-12, which defers changes in Update 2011-05 that relate to the presentation of reclassification of adjustments for entities that report items of other comprehensive income. This pronouncement is effective at the same time as ASU 2011-05 for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In July 2012, the FASB issued ASU 012-02, relating to testing intangible assets and long-lived assets for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test indefinite-lived intangible assets for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning September 15, 2012. The adoption of this pronouncement will not have a material effect on our consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes in market risk from the information provided in Item 7A. "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Item 4. Controls and Procedures

A complete discussion of our controls and procedures is included in our Annual Report on Form 10-K for the year ended December 31, 2011.

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 SEC.  Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of September 30, 2012 at the reasonable assurance level.

Our management does not expect that our disclosure controls and procedures or our 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.

Changes in Internal Control Over Financial Reporting

There have been no changes 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 September 30, 2012, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Goodwill and Intangibles

GOODWILL AND INTANGIBLES [Abstract]

Intangible Assets Disclosure [Text Block]

GOODWILL AND INTANGIBLES

We account for intangible assets with indefinite lives, including goodwill, in accordance with the applicable accounting guidance, which requires us to evaluate these assets for impairment annually, or more frequently if an indication of impairment has occurred.  Based upon our most recent evaluation, we determined that goodwill is not impaired.  We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives.

In 2011, we acquired a business providing additional manufacturing capacity for our Canadian operations for $18.8 million in cash. We have accounted for this acquisition by allocating the purchase price to the net assets acquired based on their estimated fair values at the date of acquisition, resulting in an increase to goodwill of $8.6 million and an increase of $0.5 million in intangible assets. In 2012, a post-closing adjustment was recorded that increased the purchase price and goodwill by $0.6 million. The acquisition was recorded in the Production Enhancement business segment.

BASIS OF PRESENTATION [Abstract]

Basis of Presentation and Significant Accounting Policies [Text Block]

BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Core Laboratories N.V. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information and footnote disclosures required by U.S. GAAP and should be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011 (the "2011 Annual Report").

Core Laboratories N.V. uses the equity method of accounting for investments in which it has less than a majority interest and over which it does not exercise control. Non-controlling interests have been recorded to reflect outside ownership attributable to consolidated subsidiaries that are less than 100% owned.  In the opinion of management, all adjustments considered necessary for the periods presented have been included in these financial statements.  Furthermore, the operating results presented for the three and nine months ended September 30, 2012 may not necessarily be indicative of the results that may be expected for the year ended December 31, 2012.

Core Laboratories N.V.'s balance sheet information for the year ended December 31, 2011 was derived from the 2011 audited consolidated financial statements but does not include all disclosures in accordance with U.S. GAAP.

Certain reclassifications were made to prior period amounts in order to conform to the current period presentation.  These reclassifications had no impact on the reported net income for the three and nine month periods ended September 30, 2011.

Additionally, revision adjustments were made between Services Revenue and Product Sales Revenue and between Cost of Services and Cost of Product Sales in the Consolidated Statements of Operations for 2011 which did not affect total revenues, operating income or net income for the period.

References to "Core Lab", "we", "our" and similar phrases are used throughout this Quarterly Report on Form 10-Q and relate collectively to Core Laboratories N.V. and its consolidated subsidiaries.

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). All interest and other non-operating income (expense) is attributable to the Corporate & Other area and is not allocated to specific business segments. Summarized financial information concerning our segments is shown in the following table (in thousands):

RECENT ACCOUNTING PRONOUNCEMENTS [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

12. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued ASU 2011-04 relating to fair value measurement (FASB ASC Topic 820), which amends current guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. The amendments generally represent clarification of FASB ASC Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05 which provides new guidance on the presentation of comprehensive income (FASB ASC Topic 220) in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The provisions for this pronouncement are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In September 2011, the FASB issued ASU 2011-08 relating to testing goodwill for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test goodwill for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In December 2011, the FASB issued ASU 2011-12, which defers changes in Update 2011-05 that relate to the presentation of reclassification of adjustments for entities that report items of other comprehensive income. This pronouncement is effective at the same time as ASU 2011-05 for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements.

In July 2012, the FASB issued ASU 012-02, relating to testing intangible assets and long-lived assets for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test indefinite-lived intangible assets for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning September 15, 2012. The adoption of this pronouncement will not have a material effect on our consolidated financial statements.

PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees (the "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. The benefits earned by the employees are immediately vested.  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 expire after five years at which time they are replaced with new contracts that are adjusted to include changes in the benefit obligation for the current year and redemption of the expired contracts.  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 to the insurance company based on each employee's age and current salary.

The following table summarizes the components of net periodic pension cost under this plan for the three and nine months ended September 30, 2012 and 2011 (in thousands):

	Three Months Ended						Nine Months Ended

During the nine months ended September 30, 2012, we contributed approximately $1.6 million, as determined by the insurance company, to fund the estimated 2012 premiums on investment contracts held by the Dutch Plan.

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 deferred compensation plan for employees in the United States (the "Deferred Compensation Plan"), due to certain limitations imposed by the U.S. Internal Revenue Code of 1986, as amended (the "Internal Revenue Code").  The Deferred Compensation 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 vest ratably over a period of five years. Contributions to the plan are invested in equity and other investment fund assets within life insurance policies, and carried on the balance sheet at fair value. A participant's plan benefits include the participant's deferrals, the vested portion of the employer's contributions, and deemed investment gains and losses on such amounts. The benefits under these contracts are fully vested and payment of benefits generally commences as of the last day of the month following the termination of services except that the payment of benefits for select executives generally commences on the first working day following a six month waiting period following the date of termination.

On a recurring basis, we use the market approach to value certain assets and 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) with the assistance of a third party specialist. 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 Statements of Operations.  The following table summarizes the fair value balances (in thousands):

During the three months ended September 30, 2012, we repurchased 283,513 of our common shares for $33.2 million. Included in this total were rights to 3,513 shares valued at $0.4 million that were surrendered to us pursuant to the terms of a stock-based compensation plan in consideration of the participants' tax burdens that may result from the issuance of common shares under that plan. During the nine months ended September 30, 2012, we repurchased 686,896 of our common shares for $83.4 million. Included in this total were rights to 42,103 shares valued at $5.3 million that were surrendered to us pursuant to the terms of a stock-based compensation plan in consideration of the participants' tax burdens that may result from the issuance of common shares under that plan. Such common shares, unless canceled, may be reissued for a variety of purposes such as future acquisitions, non-employee director stock awards or employee stock awards.

At the annual meeting of shareholders on May 16, 2012, the shareholders approved the cancellation of 1,138,224 shares of our common stock then held as treasury stock. These treasury shares were cancelled on August 1, 2012, after the expiration of the waiting period required under Dutch law. In accordance with ASC 505-30-30-8, we charge the excess of the cost of the treasury stock over its par value to additional paid-in capital. If additional paid-in capital is not sufficient for this charge, the remainder is charged directly to retained earnings.

In February, May, and August 2012, we paid a quarterly dividend of $0.28 per share of common stock.  In addition, on October 9, 2012, we declared a quarterly dividend of $0.28 per share of common stock for shareholders of record on October 19, 2012 and payable on November 20, 2012.

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares 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.

In 2006, we issued $300 million aggregate principal amount of Senior Exchangeable Notes (the "Exchangeable Notes") which were exchangeable into shares of Core Laboratories N.V. common stock under certain circumstances. Included in the table above are 1,083,000 shares which were added to the share count for the three months ended September 30, 2011, and 1,144,000 shares which were added to the share count for the nine months ended September 30, 2011.  These shares were included in calculating the impact to our dilutive earnings per share for the three and nine months ended September 30, 2011. All of the Exchangeable Notes were exchanged or reached maturity in 2011.

In 2006, we sold warrants that gave the holders the right to acquire our common shares. Included in the table above are 1,205,000 shares which were added to the share count for the nine months ended September 30, 2011, because the average share price exceeded the strike price of the warrants.  These shares were included in calculating the impact to our dilutive earnings per share for the nine months ended September 30, 2011. The warrants were fully settled in 2011.

The Credit Facility provides an option to increase the commitment under the Credit Facility to $350 million, if certain conditions are met.  The Credit Facility bears interest at variable rates from LIBOR plus 1.50% to a maximum of LIBOR plus 2.25%.  Any outstanding balance under the Credit Facility is due September 28, 2016 when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity at any point in time is reduced by borrowings outstanding at the time and outstanding letters of credit which totaled $17.0 million at September 30, 2012, resulting in an available borrowing capacity under the Credit Facility of $220.0 million.  In addition to those items under the Credit Facility, we had $26.4 million of outstanding letters of credit and performance guarantees and bonds from other sources as of September 30, 2012.

The terms of the Credit Facility and the Senior Notes require us to meet certain financial and operational 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 agreements. Certain of our material, wholly-owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes.

The estimated fair value of total debt at September 30, 2012 and December 31, 2011 approximated the book value of total debt. The fair value was estimated using Level 2 inputs including rates on similar debt recently issued by our peer group.
