Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

(1) Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Superior Energy Services, Inc. and subsidiaries (the Company). All significant intercompany accounts and transactions are eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the 2012 presentation.

Business

The Company is a leading provider of specialized oilfield services and equipment. As a result of the February 7, 2012 acquisition of Complete Production Services, Inc. (Complete), the Company significantly added to its geographic footprint in the U.S. land market area. The Company now offers a wider variety of products and services throughout the life cycle of an oil and gas well. The acquisition of Complete greatly expanded the Company’s ability to offer more products and services related to the completion of a well prior to full production commencing, and enhanced its full suite of intervention services used to carry out wellbore maintenance operations during a well’s producing phase. The Company provides most of the products and services necessary to maintain, enhance and extend producing wells, as well as plug and abandonment services at the end of a well’s life cycle.

The Company serves energy industry customers who focus on exploring, developing and producing oil and gas worldwide. The Company’s operations are managed and organized by both business units and geomarkets offering products and services within various phases of a well’s economic lifecycle. The Company reports its operating results in four segments: (1) Drilling Products and Services; (2) Onshore Completion and Workover Services; (3) Production Services; and (4) Subsea and Technical Solutions.

Use of Estimates

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

Major Customers and Concentration of Credit Risk

The majority of the Company’s business is conducted with major and independent oil and gas companies. The Company evaluates the financial strength of its customers and provides allowances for probable credit losses when deemed necessary.

The market for the Company’s services and products is the oil and gas industry in the U.S. and select international market areas. Oil and gas companies make capital expenditures on exploration, development and production operations. The level of these expenditures historically has been characterized by significant volatility.

The Company derives a large amount of revenue from a small number of major and independent oil and gas companies. In 2012, EOG Resources, Inc. accounted for approximately 13% of total revenue, primarily within the Onshore Completion and Workover segment. There were no customers that exceeded 10% of total revenues in 2011 and 2010.

In addition to trade receivables, other financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and derivative instruments used in hedging activities. The financial institutions in which the Company transacts business are large, investment grade financial institutions which are “well capitalized” under applicable regulatory capital adequacy guidelines, thereby minimizing its exposure to credit risks for deposits in excess of federally insured amounts and for failure to perform as the counterparty on interest rate swap agreements. The Company periodically evaluates the creditworthiness of financial institutions that may serve as a counterparty to its derivative instruments.

Cash Equivalents

The Company considers all short-term investments with a maturity of 90 days or less when purchased to be cash equivalents.

Accounts Receivable and Allowances

Trade accounts receivable are recorded at the invoiced amount or the earned amount but not yet invoiced and do not bear interest. The Company maintains allowances for estimated uncollectible receivables, including bad debts and other items. The allowance for doubtful accounts is based on the Company’s best estimate of probable uncollectible amounts in existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific identification.

Inventory

Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out or weighted-average cost methods for finished goods and work-in-process. Supplies and consumables consist principally of products used in the Company’s services provided to its customers.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, except for assets acquired using purchase accounting, which are recorded at fair value as of the date of acquisition. With the exception of certain marine assets, depreciation is computed using the straight line method over the estimated useful lives of the related assets as follows:

Buildings and improvements	3	to	40	years
Marine vessels and equipment	5	to	25	years
Machinery and equipment	2	to	25	years
Automobiles, trucks, tractors and trailers	3	to	7	years
Furniture and fixtures	2	to	10	years

Certain of the Company’s marine assets are depreciated using the units-of-production method based on the utilization of these assets and are subject to a minimum amount of annual depreciation. The units-of-production method is used for these assets because depreciation occurs primarily through use rather than through the passage of time.

The Company follows the successful efforts method of accounting for its investment in oil and natural gas properties. Under the successful efforts method, the costs of successful exploratory wells and leases containing productive reserves are capitalized. Costs incurred to drill and equip developmental wells, including unsuccessful wells, are capitalized. Other costs such as geological and geophysical costs and the drilling costs of unsuccessful exploratory wells are expensed. Leasehold and well costs are depleted on a units-of-production basis based on the estimated remaining equivalent oil and gas reserves of each field.

The Company capitalizes interest on the cost of major capital projects during the active construction period. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets. The Company capitalized approximately $12.4 million, $7.1 million and $2.7 million of interest expense in the years ended December 31, 2012, 2011 and 2010, respectively, for various capital projects.

In accordance with authoritative guidance on property, plant and equipment, long-lived assets, such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is assessed by a comparison of the carrying amount of such assets to their fair value calculated, in part, by the estimated undiscounted future cash flows expected to be generated by the assets. Cash flow estimates are based upon, among other things, historical results adjusted to reflect the best estimate of future market rates, utilization levels, and operating performance. Estimates of cash flows may differ from actual cash flows due to, among other things, changes in economic conditions or changes in an asset’s operating performance. The Company’s assets are grouped by subsidiary or division for the impairment testing, which represent the lowest level of identifiable cash flows. The Company has long-lived assets, such as facilities, utilized by multiple operating divisions that do not have identifiable cash flows. Impairment testing for these long-lived assets is based on the consolidated entity. If the asset grouping’s fair value is less than the carrying amount of those items, impairment losses are recorded in the amount by which the carrying amount of such assets exceeds the fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less estimated costs to sell. The net carrying value of assets not fully recoverable is reduced to fair value. The estimate of fair value represents the Company’s best estimate based on industry trends and reference to market transactions and is subject to variability. The oil and gas industry is cyclical and estimates of the period over which future cash flows will be generated, as well as the predictability of these cash flows, can have a significant impact on the carrying values of these assets and, in periods of prolonged down cycles, may result in impairment charges.

As a result of pursuing strategic alternatives, in February 2012, the Company entered into an agreement to sell its former Marine segment. As such, the Company concluded that indicators of impairment existed and therefore conducted a fair value assessment of the 18 liftboats comprising that segment as of December 31, 2011. This valuation included two components: estimated undiscounted cash flows and indicated valuation evidenced by tenders from prospective buyers. A weighted average was applied to the two components to obtain an estimate of the fair market value of those liftboats. Based on this valuation analysis, the Company determined that the 18 liftboats had a fair market value that was approximately $35.8 million less than their carrying value. Therefore, a reduction in the value of assets (property, plant and equipment) was recorded for approximately $35.8 million, which is included in discontinued operations on the consolidated statement of income. On March 30, 2012, the Company sold the 18 liftboats and related assets that had comprised its Marine segment.

For the year ended December 31, 2010, the Company recorded a reduction in the value of assets totaling $32.0 million in connection with liftboat components primarily related to the two partially completed liftboats, which is included in discontinued operations on the consolidated statements of income.

Goodwill

During the fourth quarter of 2012, the Company revised the internal reporting structure that is used by its chief operating decision maker in determining how to allocate the Company’s resources and, as a result, divided the Subsea and Well Enhancement segment into three segments that better reflect the Company’s product and service offerings throughout the life cycle of a well: Onshore Completion and Workover Services, Production Services, and Subsea and Technical Solutions. The Drilling Products and Services segment remained unchanged. As a result of this internal change, the Company allocated the goodwill that had been assigned to the Subsea and Well Enhancement segment to the three new segments based on each segment’s relative fair value. The Company engaged a third party valuation firm to assist with the calculation of these fair values.

In accordance with authoritative guidance on intangible assets, goodwill is tested for impairment annually as of December 31 or on an interim basis if events or circumstances indicate that the fair value of the asset has decreased below its carrying value. In order to estimate the fair value of the reporting units (which is consistent with the reported business segments), the Company used a weighting of the discounted cash flow method and the public company guideline method of determining fair value of each reporting unit. The Company weighted the discounted cash flow method 80% and the public company guideline method 20% due to differences between the Company’s reporting units and the peer companies’ size, profitability and diversity of operations. In order to validate the reasonableness of the estimated fair values obtained for the reporting units, a reconciliation of fair value to market capitalization was performed for each unit on a standalone basis. A control premium, derived from market transaction data, was used in this reconciliation to ensure that fair values were reasonably stated in conjunction with the Company’s capitalization. These fair value estimates were then compared to the carrying value of the reporting units. No impairment loss was recognized during the years ended December 31, 2012 and 2010, as the fair value of each of the reporting units exceeded its carrying amount. As of December 31, 2012, the fair value of the Drilling and Products Services segment was substantially in excess of its carrying value. The fair values of the Onshore Completion and Workover Services and Production Services segments did not substantially exceed their respective carrying values due to the fact these reporting units are primarily composed of assets acquired and liabilities assumed through the acquisition of Complete in February 2012. Therefore, the carrying values of these segments were recorded at fair value at the date of the acquisition. Additionally, the fair value of the Subsea and Technical Solutions segment did not substantially exceed its carrying value. A significant amount of judgment was involved in performing these evaluations since the results are based on estimated future events.

The Company completed its assessment as of December 31, 2011 to determine whether goodwill was impaired and as a result determined that it was more likely than not that the fair value of the former Marine segment was less than its carrying amount, indicating that goodwill was potentially impaired. As such, the Company initiated the second step of the goodwill impairment test which involved calculating the implied fair value of the goodwill by allocating the fair value of the former Marine segment to all of the assets and liabilities other than goodwill and comparing it to the carrying amount of goodwill. The Company determined that the implied fair value of the goodwill for the former Marine segment was less than its carrying value and fully wrote-off the goodwill balance of $10.3 million, which was recorded within loss from discontinued operations on the consolidated statement of income.

The following table summarizes the activity for the Company’s goodwill for the years ended December 31, 2012 and 2011 (amounts in thousands):

If, among other factors, (1) the Company’s market capitalization declines and remains below its stockholders’ equity, (2) the fair value of the reporting units decline, or (3) the adverse impacts of economic or competitive factors are worse than anticipated, the Company could conclude in future periods that impairment losses are required.

Notes Receivable

The Company’s wholly owned subsidiary, Wild Well Control, Inc. (Wild Well), has decommissioning obligations related to the Bullwinkle platform. Notes receivable consist of a commitment from the seller of the platform towards its eventual abandonment. Pursuant to an agreement with the seller, the Company will invoice the seller an agreed upon amount at the completion of certain decommissioning activities. The gross amount of this obligation totaled $115.0 million and is recorded at present value using an effective interest rate of 6.58%. The related discount is amortized to interest income based on the expected timing of the platform’s removal. During the second quarter of 2012, the Company revised its timing estimate for the Bullwinkle platform removal, resulting in a significant reduction of the present value of the notes receivable. The Company recorded interest income related to notes receivable of $2.8 million, $4.5 million and $4.5 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Intangible and Other Long-Term Assets

Intangible and other long-term assets consist of the following as of December 31, 2012 and 2011 (amounts in thousands):



	December 31, 2012			December 31, 2011
	Gross	Accumulated	Net	Gross	Accumulated	Net

Total	$ 563,554	$ (53,148)	$ 510,406	$ 950,756	$ (20,620)	$ 930,136

Customer relationships, tradenames, and non-compete agreements are amortized using the straight line method over the life of the related asset with weighted average useful lives of 17 years, 13 years, and 3 years, respectively. Amortization expense (exclusive of debt issuance costs) was approximately $24.0 million, $3.4 million and $3.3 million for the years ended December 31, 2012, 2011 and 2010, respectively. Estimated annual amortization of intangible assets (exclusive of debt acquisition costs) will be approximately $27.1 million for 2013, $26.9 million for 2014, $26.2 million for 2015, $25.7 million for 2016 and $25.0 million for 2017, excluding the effects of any acquisitions or dispositions subsequent to December 31, 2012.

Debt issuance costs are amortized primarily using the effective interest method over the life of the related debt agreements with a weighted average useful life of 7 years. Amortization of debt issuance costs is recorded in interest expense, net of amounts capitalized within the consolidated statements of income.

In accordance with the asset purchase agreement between Wild Well and Shell Offshore, Inc. to acquire the Bullwinkle platform and its related assets and to assume the related decommissioning obligations, Wild Well obtained a $50.0 million performance bond and funded its portion of $50.0 million into an escrow account. Included in intangible and other long-term assets, net is escrowed cash of $50.3 million and $50.2 million as of December 31, 2012 and 2011, respectively.

In connection with the December 2011 issuance of the Company’s $800 million of 7 1/8% unsecured senior notes due 2021, certain restrictions were placed on the proceeds from the issuance of these notes. These restrictions limited the Company’s use of the proceeds, net of fees and expenses from the issuance, to the acquisition of Complete. As of December 31, 2011, the Company held $785.3 million in other long-term assets as net proceeds from the issuance of these notes, which were used to partially fund the acquisition of Complete on February 7, 2012.

Decommissioning Liabilities

The Company records estimated future decommissioning liabilities in accordance with the authoritative guidance related to asset retirement obligations (decommissioning liabilities), which requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred, with a corresponding increase in the carrying amount of the related long-lived asset. Subsequent to initial measurement, the decommissioning liability is required to be accreted each period to present value.

The Company’s decommissioning liabilities associated with the Bullwinkle platform and its related assets consist of costs related to the plugging of wells, the removal of the related facilities and equipment, and site restoration. Whenever practical, the Company utilizes its own equipment and labor services to perform well abandonment and decommissioning work. When the Company performs these services, all recorded intercompany revenues and related costs of services are eliminated in the consolidated financial statements. The recorded decommissioning liability associated with a specific property is fully extinguished when the property is abandoned. The recorded liability is first reduced by all cash expenses incurred to abandon and decommission the property. If the recorded liability exceeds (or is less than) the Company’s total costs, then the difference is reported as income (or loss) within revenue during the period in which the work is performed.

The Company reviews the adequacy of its decommissioning liabilities whenever indicators suggest that the estimated cash flows needed to satisfy the liability have changed materially. The Company reviews its estimates for the timing of these expenditures on a quarterly basis. As a result of continuing development activities, the Company revised its estimates during the second quarter of 2012 relating to the timing of decommissioning work on its Bullwinkle assets, including a 10 year postponement of the platform decommissioning. This change in estimate resulted in a significant reduction in the present value of decommissioning liabilities.

In connection with the acquisition of Complete, the Company assumed approximately $4.6 million of estimated decommissioning liabilities associated with costs to plug and abandon disposal wells at the end of the service lives of the assets.

The following table summarizes the activity for the Company’s decommissioning liabilities for the years ended December 31, 2012 and 2011 (in thousands):



	Years Ended
	December 31,
	2012	2011

Decommissioning liabilities, December 31, 2011 and 2010, respectively	$ 123,176	$ 117,716

Total decommissioning liabilities, December 31, 2012 and 2011, respectively	93,053	123,176

Less: current portion of decommissioning liabilities as of December 31, 2012 and 2011, respectively	-	14,956

Long-term decommissioning liabilities, December 31, 2012 and 2011, respectively	$ 93,053	$ 108,220

Revenue Recognition

Products and services are generally sold based upon purchase orders or contracts with customers that include fixed or determinable prices. Revenue is recognized when services or equipment are provided and collectability is reasonably assured. The Company’s drilling products and services are billed on a day rate basis, and revenue from the sale of equipment is recognized when the title to the equipment has been transferred. Reimbursements from customers for the cost of drilling products and services that are damaged or lost down-hole are reflected as revenue at the time of the incident. The Company contracts for the remainder of its products and services either on a day rate or turnkey basis, with a vast majority of its projects conducted on a day rate basis. The Company accounts for the revenue and related costs on large-scale platform decommissioning contracts on the percentage-of-completion method utilizing costs incurred as a percentage of total estimated costs. The Company recognizes oil and gas revenue from its interests in producing wells as oil and natural gas is sold.

Taxes Collected from Customers

In accordance with authoritative guidance related to taxes collected from customers and remitted to governmental authorities, the Company elected to net taxes collected from customers against those remitted to government authorities in the financial statements consistent with the historical presentation of this information.

Income Taxes

The Company accounts for income taxes and the related accounts under the asset and liability method. Deferred income taxes reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws and rates that are in effect when the temporary differences are expected to reverse. The effect of a change in tax rates on the deferred income taxes is recognized in income in the period in which the change occurs. A valuation allowance is recorded when management believes it is more likely than not that at least some portion of any deferred tax asset will not be realized.

The Company has adopted authoritative guidance surrounding accounting for uncertainty in income taxes. It is the Company’s policy to recognize interest and applicable penalties related to uncertain tax positions in income tax expense.

Earnings per Share

Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed in the same manner as basic earnings per share except that the denominator is increased to include the number of additional common shares that could have been outstanding assuming the exercise of stock options, conversion of restricted stock units and the vesting of outstanding restricted stock issued in the acquisition of Complete.

Stock options for approximately 2,100,000 shares, 540,000 shares and 1,650,000 shares were excluded in the computation of diluted earnings per share for the years ended December 31, 2012, 2011 and 2010, respectively, as the effect would have been anti-dilutive.

Discontinued Operations

The Company classifies assets and liabilities of a disposal group as held for sale and discontinued operations if the following criteria are met: (1) management, with appropriate authority, commits to a plan to sell a disposal group; (2) the asset is available for immediate sale in its current condition; (3) an active program to locate a buyer and other actions to complete the sale have been initiated; (4) the sale is probable; (5) the disposal group is being actively marketed for sale at a reasonable price; and (6) actions required to complete the plan of sale indicate it is unlikely that significant changes to the plan of sale will occur or that the plan will be withdrawn. Once deemed as held for sale, the Company no longer depreciates the assets of the disposal group. Upon sale, the Company calculates the gain or loss associated with the disposition by comparing the carrying value of the assets less direct costs of the sale with the proceeds received. In the consolidated statements of income, losses from discontinued operations are presented, net of tax effect, as a separate caption below net income from continuing operations.

Fair Value Measurements

The company follows the authoritative guidance for fair value measurements relating to financial and nonfinancial assets and liabilities, including presentation of required disclosures herein. This guidance establishes a fair value framework requiring the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets and liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows:

Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities;

Level 2: Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical assets or liabilities in inactive markets or model-derived valuations or other inputs that can be corroborated by observable market data; and

Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.

Financial Instruments

The fair value of the Company’s financial instruments of cash equivalents, accounts receivable, accounts payable, accrued expenses and borrowings under its credit facility approximates their carrying amounts due to their short maturity or market interest rates. The fair value of the Company’s debt was approximately $1,960.0 million and $1,749.8 million as of December 31, 2012 and 2011, respectively. The fair value of these debt instruments is determined by reference to the market value of the instrument as quoted in an over-the-counter market.

Foreign Currency

Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated using the exchange rates in effect at the balance sheet dates, and the resulting translation adjustments are reported as accumulated other comprehensive loss in the Company’s stockholders’ equity.

For international subsidiaries where the functional currency is the U.S. dollar, financial statements are remeasured into U.S. dollars using the historical exchange rate for most of the long-term assets and liabilities and the balance sheet date exchange rate for most of the current assets and liabilities. An average exchange rate is used for each period for revenues and expenses. These transaction gains and losses, as well as any other transactions in a currency other than the functional currency, are included in general and administrative expenses in the consolidated statements of income in the period in which the currency exchange rates change. For the years ended December 31, 2012, 2011 and 2010, the Company recorded approximately ($2.7) million, $1.4 million and $1.6 million of foreign currency gains (losses), respectively.

Stock-Based Compensation

In accordance with authoritative guidance related to stock compensation, the Company records compensation costs relating to share-based payment transactions and includes such costs in general and administrative expenses in the consolidated statement of income. The cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award). Excess tax benefits of awards that are recognized in equity related to stock option exercises and restricted stock vesting are reflected as financing cash flows.

Derivative Instruments and Hedging Activities

The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. Interest rate swap agreements that are effective at hedging the fair value of fixed-rate debt agreements are designated and accounted for as fair value hedges. The Company also assesses, both at inception of the hedging relationship and on an ongoing basis, whether the derivatives used in hedging relationships are highly effective in offsetting changes in fair value.

In an attempt to achieve a more balanced debt portfolio, the Company enters into interest rate swaps. Under these agreements, the Company is entitled to receive semi-annual interest payments at a fixed rate and is obligated to make quarterly interest payments at a variable rate. The Company had fixed-rate interest on approximately 74% and 87% of its long-term debt as of December 31, 2012 and 2011, respectively. The Company had notional amounts of $100 million and $150 million, respectively, related to interest rate swaps with a variable interest rate, adjusted every 90 days, based on LIBOR plus a fixed margin as of December 31, 2012 and 2011, respectively.

From time to time, the Company may enter into forward foreign exchange contracts to hedge the impact of foreign currency fluctuations. The Company does not enter into forward foreign exchange contracts for trading purposes. During the years ended December 31, 2012 and 2011, the Company did not hold any foreign currency forward contracts. During the year ended December 31, 2010, the Company held foreign currency forward contracts outstanding in order to hedge exposure to currency fluctuations. These contracts were not designated as hedges, for hedge accounting treatment, and were marked to fair market value each period and changes in fair value were recognized in earnings.

Equity–Method Investments

Investments in entities that are not controlled by the Company, but where the Company has the ability to exercise significant influence over the operations, are accounted for using the equity-method. The Company’s share of the income or losses of these entities is reflected as earnings or losses from equity-method investments in its consolidated statements of income.

Self-Insurance Reserves

The Company is self-insured, through deductibles and retentions, up to certain levels for losses under its insurance programs. With the Company’s growth, the Company has elected to retain more risk by increasing its self-insurance levels. The Company accrues for these liabilities based on estimates of the ultimate cost of claims incurred as of the balance sheet date. The Company regularly reviews the estimates of reported and unreported claims and provides for losses through reserves. The Company obtains actuarial reviews to evaluate the reasonableness of internal estimates for losses related to workers’ compensation, auto liability and group medical on an annual basis.

Recently Issued Accounting Pronouncements

In December 2011, the FASB issued ASU 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities”. This accounting standard requires an entity to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position as well as instruments and transactions executed under a master netting or similar arrangement and was issued to enable users of financial statements to understand the effects or potential effects of those arrangements on its financial position. This ASU is required to be applied retrospectively and is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. As this accounting standard only requires enhanced disclosure, the adoption of this standard is not expected to have an impact on the Company’s consolidated financial position or results of operations.

Subsequent Events

In accordance with authoritative guidance, the Company has evaluated and disclosed all material subsequent events that occurred after the balance sheet date, but before financial statements were issued.

Acquisitions [Abstract]

Acquisitions

(3) Acquisitions

Complete Production Services

On February 7, 2012, the Company acquired Complete in a cash and stock merger transaction valued at approximately $2,914.8 million. Complete focused on providing specialized completion and production services and products that help oil and gas companies develop hydrocarbon reserves, reduce costs and enhance production. Complete’s operations were located throughout the U.S. and Mexico. The acquisition of Complete substantially expanded the size and scope of the Company’s services. Management believes that this acquisition positions the combined company to be better equipped to compete with the larger oilfield service companies and to expand internationally. Complete’s operations are reported within the Company’s Onshore Completion and Workover Services and Production Services segments.

Pursuant to the merger agreement, Complete stockholders received 0.945 of a share of the Company’s common stock and $7.00 cash for each share of Complete’s common stock outstanding at the time of the acquisition. In total, the Company paid approximately $553.3 million in cash and issued approximately 74.7 million shares valued at approximately $2,308.2 million (based on the closing price of the Company’s common stock on the acquisition date of $30.90). Additionally, the Company paid $676.0 million, inclusive of a $26.0 million prepayment premium, to redeem $650 million of Complete’s 8.0% senior notes. The Company also assumed all outstanding stock options and shares of non-vested and unissued restricted stock held by Complete’s employees and directors at the time of acquisition.

Complete’s stock options and shares of restricted stock outstanding at closing were converted into the Company’s options and restricted stock using a conversion ratio of 1.1999. The estimated fair value associated with the Company’s options issued in exchange for Complete’s options was approximately $58.1 million based on a Black-Scholes valuation model. $56.6 million of this value was attributable to service rendered prior to the date of acquisition, of which $52.7 million was recorded as part of the consideration transferred and $3.9 million was recorded as an expense. The remaining $1.5 million will be expensed over the remaining service term of the replacement stock option awards. In addition, $0.6 million of replacement restricted stock awards was attributable to service rendered prior to the date of acquisition and recorded as part of the consideration transferred. An additional $18.2 million will be expensed over the remaining service term of the replacement restricted stock awards.

The transaction has been accounted for using the acquisition method of accounting which requires that, among other things, assets acquired and liabilities assumed be recorded at their fair values as of the acquisition date. As of December 31, 2012, the Company finalized the determination of the assets acquired and liabilities assumed. The Company recorded adjustments to the initial purchase price allocation to reflect new information obtained about facts and circumstances that existed as of the acquisition date. The following table summarizes the consideration paid and the fair value of the assets acquired and liabilities assumed as of the acquisition date (in thousands):



Assets:
Current assets		$ 738,456
Property, plant and equipment		1,221,808
Goodwill		1,922,689
Intangible and other long-term assets		372,713
		-
Liabilities:
Current liabilities		231,951
Deferred income taxes		403,403
Other long-term liabilities		29,519

Net assets acquired		$ 3,590,793

Included in current assets acquired is approximately $214.6 million of cash, and accounts receivable with a fair value of approximately $443.7 million. The gross amount due from customers is approximately $449.0 million, of which approximately $5.3 million is deemed to be doubtful.

Property, Plant and Equipment

A step-up adjustment of approximately $44.2 million was recorded to present property, plant and equipment acquired at its estimated fair value. The weighted average useful life used to calculate depreciation of the step-up related to property, plant and equipment is approximately 6 years.

Goodwill

Goodwill of approximately $1,922.7 million was recognized as a result of this acquisition and was calculated as the excess of the consideration paid over the net assets recognized and represents estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. It includes access to new product and service offerings, an experienced management team and workforce, and other benefits that the Company believes will result from the combination of the operations, and any other intangible assets that do not qualify for separate recognition. None of the goodwill related to this acquisition will be deductible for tax purposes. The goodwill has been allocated between the Onshore Completion and Workover Services and the Production Services segments based on the relative fair value of these segments.

Intangible Assets

The Company identified intangible assets related to trade names and customer relationships. The following table summarizes the fair value estimates recorded for the identifiable intangible assets (in thousands) and their estimated useful lives:



	Estimated Fair Value	Estimated Useful Life

Customer relationships	$ 315,000	17 years
Tradenames	35,000	10 years

Total identifiable intangible assets	$ 350,000

Deferred Income Taxes

The Company provided deferred income taxes and other tax liabilities as part of the acquisition accounting related to the estimated fair value of acquired intangible assets and property, plant and equipment, as well as for uncertain tax positions taken in prior year tax returns. An adjustment of approximately $125.5 million was recorded to present the deferred tax assets and liabilities and other tax liabilities at fair value.

Acquisition Related Expenses

Acquisition related expenses totaled approximately $33.3 million, of which approximately $28.8 million was recorded in the year ended December 31, 2012. The remainder was recorded in the three months ended December 31, 2011. These acquisition related costs include expenses directly related to acquiring Complete and have been recorded in general and administrative expenses in the consolidated statements of income.

Other Acquisitions

In August 2012, the Company acquired 100% of the equity interest in a company that provides mechanical wireline, electric line and well testing services to oil and gas companies in Argentina. This acquisition provides the Company with a platform for the continued expansion in the South American market area. The Company paid $25.5 million at closing along with an additional $5.6 million payable when shareholders’ equity as of the closing date was finalized. The Company has also recorded a current liability of approximately $6.5 million for contingent consideration based upon certain performance metrics. Additionally, the Company deposited $8.0 million in an escrow account on behalf of the sellers for the settlement of certain liabilities. Goodwill of approximately $22.6 million was recognized as a result of this acquisition and was calculated as the excess of the consideration paid over the net assets recognized and represents estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. None of the goodwill related to this acquisition will be deductible for tax purposes. All of the goodwill was originally assigned to the Subsea and Well Enhancement segment. As a result of the Company’s revised internal reporting structure, the goodwill related to this acquisition was allocated among the three new segments based on each segment’s relative fair value.

Current Earnings and Pro Forma Impact of Acquisitions

The revenue and earnings related to Complete and certain other acquisitions included in the Company’s consolidated statement of income for the year ended December 31, 2012, and the revenue and earnings of the Company on a consolidated basis as if these acquisitions had occurred on January 1, 2011, are set forth in the table below (in thousands, except per share amounts). The earnings related to Complete and certain other acquisitions included in the Company’s consolidated statement of income for the year ended December 31, 2012 do not include interest expense or other corporate costs. The pro forma results include (i) the amortization associated with the acquired intangible assets, (ii) additional depreciation expense related to adjustments to property, plant and equipment, (iii) additional interest expense associated with debt used to fund a portion of the acquisitions, (iv) a reduction to interest expense associated with repayment of the acquirees’ debt, and (v) operating results of certain acquisitions of Complete prior to February 7, 2012. For the year ended December 31, 2012, these pro forma results exclude approximately $81.6 million of non-recurring expenses, of which $48.4 million was recorded by Complete prior to February 7, 2012. These nonrecurring expenses include banking, legal, consulting and accounting fees, and change of control and other acquisition related expenses. The pro forma results do not include any potential synergies, cost savings or other expected benefits of the acquisition. Accordingly, the pro forma results should not be considered indicative of the results that would have occurred if the acquisition and related borrowings had been consummated as of January 1, 2011, nor are they indicative of future results.



	Revenue	Net income from continuing operations	Basic earnings per share	Diluted earnings per share


Actual results of acquisitions from date
of acquisitions through December 31, 2012	$ 2,225,013	$ 140,806	$ 1.61	$ 1.59

Supplemental pro forma for the Company:

Year ended December 31, 2012	$ 4,858,464	$ 428,276	$ 2.70	$ 2.70

Year ended December 31, 2011	$ 4,214,617	$ 390,209	$ 2.53	$ 2.49

The Company has no off-balance sheet financing arrangements related to potential additional consideration that may be payable as a result of the future operating performance of acquired businesses. As of December 31, 2012, the maximum additional consideration payable was approximately $10.0 million, all of which was included in accrued expenses. The Company paid additional consideration of $6.0 million during the year ended December 31, 2012, as a result of prior acquisitions. Of the consideration paid in 2012, $3.0 million was attributable to acquisitions that occurred prior to the adoption of revised authoritative guidance and therefore was capitalized during the year ended December 31, 2012 when the amount was fixed and determinable. The remaining $3.0 million paid in the year ended December 31, 2012 had been capitalized upon acquisition.

(4) Discontinued Operations

On February 15, 2012, the Company sold one of its derrick barges and received proceeds of approximately $44.5 million, inclusive of selling costs. The Company recorded a pre-tax loss of approximately $3.1 million, inclusive of approximately $9.7 million of goodwill, during the year ended December 31, 2012 in connection with this sale. This business was previously reported in the former Subsea and Well Enhancement segment. The operations and loss on the sale of this disposal group have been reported within loss from discontinued operations in the consolidated statements of income for all periods presented.

On March 30, 2012, the Company sold 18 liftboats and related assets comprising its former Marine segment. The Company received cash proceeds of approximately $138.6 million, inclusive of working capital and selling costs. In connection with the sale, the Company repaid approximately $12.5 million in U.S. Government guaranteed long-term financing (see note 8). Additionally, the Company paid approximately $4.0 million of make-whole premiums and wrote off approximately $0.7 million of unamortized loan costs as a result of this repayment. The Company’s total pre-tax loss on the disposal of this segment was approximately $56.1 million, which includes a $46.1 million write off of long-lived assets and goodwill that was recorded in the fourth quarter of 2011 in order to approximate the segment’s indicated fair value and an additional loss of $10.0 million recorded in the first quarter of 2012, comprised of an approximate $3.6 million loss on sale of assets and approximately $6.4 million of additional costs related to the disposition. During the year ended December 31, 2011, the Company sold seven liftboats from the former Marine segment for approximately $22.3 million, net of sales commissions, and recorded a pre-tax gain of approximately $8.6 million. The operations and loss on the sale of this disposal group have been reported within loss from discontinued operations in the consolidated statements of income for all periods presented.

In connection with the review for impairment of long-lived assets in accordance with authoritative guidance, the Company recorded approximately $35.8 million as a reduction in the value of the 18 liftboats that comprised the former Marine segment during the year ended December 31, 2011 as the indicated valuation from potential buyers for such assets was less than their carrying values. During 2010, the Company recorded a reduction in the value of assets totaling $32.0 million in connection with liftboat components primarily related to partially completed liftboats.

The Company had approximately $63.5 million and $23.2 million of leasehold improvements as of December 31, 2012 and 2011, respectively. These leasehold improvements are depreciated over the shorter of the life of the asset or the term of the lease using the straight line method. Depreciation expense (excluding depletion, amortization and accretion) was approximately $480.0 million, $224.6 million, and $207.7 million for the years ended December 31, 2012, 2011 and 2010, respectively, which includes amounts recorded within loss from discontinued operations on the consolidated statements of income.

Inventory and Other Current Assets [Abstract]
Inventory and Other Current Assets	(6) Inventory and Other Current Assets Inventory and other current assets includes approximately $136.5 million and $83.1 million of inventory as of December 31, 2012 and 2011, respectively. The Company’s inventory balance as of December 31, 2012 consisted of approximately $63.7 million of finished goods, $6.0 million of work-in-process, $5.0 million of raw materials and $61.8 million of supplies and consumables. The Company’s inventory balance as of December 31, 2011 consisted of approximately $39.0 million of finished goods, $2.3 million of work-in-process, $5.4 million of raw materials and $36.4 million of supplies and consumables. Inventory and other current assets also includes approximately $18.5 million and $133.4 million of costs incurred and estimated earnings in excess of billings on uncompleted contracts as of December 31, 2012 and 2011, respectively. The Company follows the percentage-of-completion method of accounting for applicable contracts. In December 2007, Wild Well entered into contractual arrangements pursuant to which it decommissioned seven downed oil and gas platforms and related well facilities located in the Gulf of Mexico for a fixed sum of $750 million. The contract contained certain covenants primarily related to Wild Well’s performance of the work. As of December 31, 2012, the work on this project was complete, and all amounts due the Company pursuant to this contract have been collected. As of December 31, 2011, there were approximately $129.7 million of costs and estimated earnings in excess of billings related to this contract included in other current assets. Additionally, available-for-sale securities are included in inventory and other current assets. On April 17, 2012, SandRidge Energy Inc. (NYSE: SD) (SandRidge) completed its acquisition of Dynamic Offshore, at which time the Company received approximately $34.1 million in cash and approximately $51.6 million in shares of SandRidge stock (approximately 7.0 million shares valued at $7.33 per share) in consideration for its 10% interest in Dynamic Offshore (see note 7). In accordance with authoritative guidance related to equity securities, the Company is accounting for the shares received through this transaction as available-for-sale securities. The changes in fair values, net of applicable taxes, on available-for-sale securities are recorded as unrealized holding gains (losses) on securities as a component of accumulated other comprehensive loss in shareholders' equity. During the year ended December 31, 2012, the Company sold approximately 5.6 million shares of SandRidge stock for approximately $41.9 million, resulting in a realized gain of approximately $0.9 million. The fair value of the remaining 1.4 million shares as of December 31, 2012 was approximately $9.2 million. During the year ended December 31, 2012, the Company recorded an unrealized loss on these securities of approximately $1.4 million, of which approximately $0.9 million was reported within accumulated other comprehensive loss, net of tax benefit of approximately $0.5 million. The Company evaluates whether unrealized losses on investments in securities are other-than-temporary, and if it is believed the unrealized losses are other-than-temporary, an impairment charge is recorded. There were no other-than-temporary impairment losses recognized during the year ended December 31, 2012.

On February 7, 2012, in connection with the Complete acquisition, the Company amended its credit facility to increase the revolving borrowing capacity to $600.0 million from $400.0 million, and to include a $400.0 million term loan. The principal balance of the term loan is payable in installments of $5.0 million on the last day of each fiscal quarter, which began on June 30, 2012. Any amounts outstanding on the revolving portion and the term loan of the credit facility are due on February 7, 2017. Costs associated with the credit facility totaled approximately $24.7 million. These costs have been capitalized and will be amortized over the term of the credit facility.

As of December 31, 2012, the Company had no amounts outstanding under the revolving portion of the credit facility. The Company had approximately $49.0 million of letters of credit outstanding, which reduce the Company’s borrowing availability under this portion of the credit facility. Amounts borrowed under the credit facility bear interest at LIBOR plus margins that depend on the Company’s leverage ratio. Indebtedness under the credit facility is secured by substantially all of the Company’s assets, including the pledge of the stock of the Company’s principal domestic subsidiaries. The credit facility contains customary events of default and requires that the Company satisfy various financial covenants. It also limits the Company’s ability to pay dividends or make other distributions, make acquisitions, make changes to the Company’s capital structure, create liens or incur additional indebtedness. As of December 31, 2012, the Company was in compliance with all such covenants.

In August 2012, the Company redeemed $150 million, or 50%, of the principal amount of its $300 million 6 7/8% unsecured senior notes due 2014 at 100% of face value. This redemption resulted in a loss on early extinguishment of debt of approximately $2.3 million related to the write off of debt acquisition costs and notes discount. The indenture governing the remaining $150 million 6 7/8% senior notes outstanding requires semi-annual interest payments on June 1^st and December 1^st of each year through the maturity date of June 1, 2014. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. As of December 31, 2012, the Company was in compliance with all such covenants.

The Company has outstanding $500 million of 6 3/8% unsecured senior notes due 2019. The indenture governing the 6 3/8% senior notes requires semi-annual interest payments on May 1^st and November 1^stof each year through the maturity date of May 1, 2019. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. As of December 31, 2012, the Company was in compliance with all such covenants.

The Company also has outstanding $800 million of 7 1/8% unsecured senior notes due 2021. The indenture governing the 7 1/8% senior notes requires semi-annual interest payments on June 15^th and December 15^thof each year through the maturity date of December 15, 2021. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. As of December 31, 2012, the Company was in compliance with all such covenants.

In connection with the sale of the assets comprising the former Marine segment in March 2012, the Company repaid $12.5 million of U.S. Government guaranteed long-term financing (see note 4). The Company also paid approximately $4.0 million of make-whole premiums and wrote off approximately $0.7 million of unamortized loan costs as a result of this repayment. These expenses have been reported in discontinued operations, net of income tax in the consolidated statement of income.

Annual maturities of long-term debt for each of the five fiscal years following December 31, 2012 and thereafter are as follows (in thousands):



2013	$ 20,000
2014	170,000

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based and Long-Term Compensation

(9) Stock-Based and Long-Term Compensation

The Company maintains various stock incentive plans that provide long-term incentives to the Company’s key employees, including officers, directors, consultants and advisors (Eligible Participants). Under the incentive plans, the Company may grant incentive stock options, non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights, other stock-based awards or any combination thereof to Eligible Participants. The Compensation Committee of the Company’s Board of Directors establishes the terms and conditions of any awards granted under the plans, provided that the exercise price of any stock options granted may not be less than the fair value of the common stock on the date of the grant.

Stock Options

The Company has granted non-qualified stock options under its stock incentive plans. The stock options generally vest in equal installments over three years and expire in ten years. Non-vested stock options are generally forfeitable upon termination of employment. During 2012, the Company granted 78,043 non-qualified stock options under these same terms and also assumed and converted 2,668,046 non-qualified stock options related to the merger with Complete.

In accordance with authoritative guidance related to stock-based compensation, the Company recognizes compensation expense for stock option grants based on the fair value at the date of grant using the Black-Scholes-Merton option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected life of the stock option and the expected forfeiture rate. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected life of the stock option. The following table presents the fair value of stock option grants made during the years ended December 31, 2012, 2011 and 2010, as well as the options assumed and converted in the Complete acquisition, and the related assumptions used to calculate the fair value:



	Years Ended December 31,
	2012	2011	2010
	Actual	Actual	Actual

Weighted average fair value of grants	$ 21.76	$ 13.54	$ 10.56

Black-Scholes-Merton Assumptions:
Risk free interest rate	0.41%	0.85%	2.07%
Expected life (years)	2	5	4
Volatility	55.27%	56.31%	49.28%
Dividend yield	-	-	-

For 2012, the expected life of options assumed and converted in connection with the Complete acquisition was approximately two years, and the expected life of new option grants issued in 2012 was approximately five years, resulting in a weighted average life of approximately two years.

The Company’s compensation expense related to stock options for the years ended December 31, 2012, 2011 and 2010 was approximately $4.8 million, $3.3 million and $15.5 million, respectively, which is reflected in general and administrative expenses in the consolidated statements of income. During 2010, the Company modified 1,418,395 stock options, affecting three employees in connection with the management transition of certain executive officers. These stock options were accelerated to vest by December 31, 2010. The Company incurred incremental compensation cost of approximately $9.8 million during 2010 as a result of this modification.

The following table summarizes stock option activity for the years ended December 31, 2012, 2011 and 2010:



	Number of Options	Weighted Average Option Price	Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)

Options expected to vest	409,189	$ 27.66	8.4	$ -

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on December 31, 2012 and the stock option price, multiplied by the number of “in-the-money” stock options) that would have been received by the stock option holders if all the options had been exercised on December 31, 2012. The Company expects all of its remaining non-vested options to vest as they are primarily held by its officers and senior managers.

The total intrinsic value of stock options exercised during the year ended December 31, 2012 (the difference between the stock price upon exercise and the stock option price) was approximately $40.4 million. The Company received approximately $14.8 million, $10.3 million and $0.9 million during the years ended December 31, 2012, 2011 and 2010, respectively, from employee stock option exercises. In accordance with authoritative guidance related to stock-based compensation, the Company has reported the tax benefits of approximately $0.6 million, $7.4 million, $0.6 million from the exercise of stock options for the years ended December 31, 2012, 2011 and 2010, respectively, as financing cash flows in the consolidated statement of cash flows.

Restricted Stock

During the year ended December 31, 2012, the Company granted 362,904 shares of restricted stock to its employees. Shares of restricted stock generally vest in equal annual installments over three years. On February 7, 2012 the Company also assumed and converted 609,743 shares of restricted stock related to the Complete acquisition. Non-vested shares are generally forfeited upon termination of employment. With the exception of the non-vested shares of restricted stock assumed and converted as a result of the Complete acquisition, holders of shares of restricted stock are entitled to all rights of a stockholder of the Company with respect to the restricted stock, including the right to vote the shares and receive any dividends or other distributions. Compensation expense associated with restricted stock is measured based on the grant date fair value of our common stock outstanding for the years ended December 31, 2012, 2011 and 2010. The Company’s compensation expense related to restricted stock for years ended December 31, 2012, 2011 and 2010 was approximately $17.0 million, $6.0 million and $11.4 million, respectively, which is reflected in general and administrative expenses in the consolidated statements of income.

Restricted Stock Units

Each non-employee director is issued annually a number of Restricted Stock Units (RSUs) having an aggregate dollar value determined by the Company’s Board of Directors. The exact number of RSUs granted is determined by dividing the aggregate dollar value determined by the Company’s Board of Directors by the fair market value of the Company’s common stock on the day of the annual stockholders’ meeting. If the director’s election occurs at a time other than at the annual meeting, the director will receive a pro rata number of RSUs based on the number of months between his election date and the anniversary of the last annual stockholder meeting. An RSU represents the right to receive from the Company, within 30 days of the date the director ceases to serve on the Board, one share of the Company’s common stock. As of December 31, 2012, there were 257,215 RSUs outstanding. The Company’s expense related to RSUs for the years ended December 31, 2012, 2011 and 2010 was approximately $2.4 million, $1.2 million and $1.2 million, respectively, which is reflected in general and administrative expenses in the consolidated statements of income.

Performance Share Units

The Company has issued performance share units (PSUs) to its employees as part of the Company’s long-term incentive program. There is a three-year performance period associated with each PSU grant. The two performance measures applicable to all participants are the Company’s return on invested capital and total stockholder return relative to those of the Company’s pre-defined “peer group.” If the participant has met specified continued service requirements, the PSUs will settle in cash or a combination of cash and up to 50% of equivalent value in the Company’s common stock, at the discretion of the Compensation Committee. As of December 31, 2012, there were 295,965 PSUs outstanding (94,562, 74,024 and 127,379 related to performance periods ending December 31, 2013, 2014 and 2015, respectively).

Under this stock purchase plan, eligible employees can purchase shares of the Company’s common stock at a discount. The Company received approximately $2.9 million, $2.2 million and $1.9 million related to shares issued under this plan for years ended December 31, 2012, 2011 and 2010, respectively.

The Company also has a non-qualified deferred compensation plan for its non-employee directors which allows each director to defer up to 100% of their cash compensation paid by the Company to the plan. Additionally, participating directors may defer up to 100% of the shares of common stock they are entitled to receive in connection with the payout of RSUs. Payments are made to participants based on their annual enrollment elections and plan balances. Participants earn a return on their deferred compensation that is based on hypothetical investments in certain mutual funds. Changes in market value of these hypothetical participant investments are reflected as an adjustment to the deferred compensation liability of the Company with an offset to compensation expense (see note 14). As of December 31, 2012 and 2011, the liability of the Company to the participants was approximately $13.5 million and $13.0 million, respectively, which reflects the accumulated participant deferrals and earnings (losses) as of that date. These amounts are recorded in other long-term liabilities. Additionally as of December 31, 2012 and 2011, the Company had approximately $0.1 million and $2.8 million in accounts payable in anticipation of pending payments. For the years ended December 31, 2012, 2011 and 2010, the Company recorded compensation income (expense) of approximately $1.6 million, $0.1 million and ($1.8) million, respectively, related to the earnings and losses of the deferred compensation plan liability. The Company makes contributions that approximate the participant deferrals into various investments, principally life insurance that is invested in mutual funds similar to the participants’ hypothetical investment elections. Changes in market value of the investments and life insurance are reflected as adjustments to the deferred compensation plan asset with an offset to other income (expense). As of December 31, 2012 and 2011, the deferred compensation plan asset was approximately $11.3 million and $10.6 million, respectively, and is recorded in intangible and other long-term assets, net. For the years ended December 31, 2012, 2011 and 2010, the Company recorded other income (expense) of ($0.7) million, ($0.2) million, $0.8 million, respectively, related to the earnings and losses of the deferred compensation plan assets.

Supplemental Executive Retirement Plan

The Company has a supplemental executive retirement plan (SERP). The SERP provides retirement benefits to the Company’s executive officers and certain other designated key employees. The SERP is an unfunded, non-qualified defined contribution retirement plan, and all contributions under the plan are unfunded credits to a notional account maintained for each participant. Under the SERP, the Company will generally make annual contributions to a retirement account based on age and years of service. During 2012, 2011 and 2010, the participants in the plan received contributions ranging from 5% to 35% of salary and annual cash bonus, which totaled approximately $1.8 million, $1.0 million and $5.5 million, respectively. The Company may also make discretionary contributions to a participant’s account. In 2010, the Company made a discretionary contribution to the account of its former chief operating officer in the amount of $4.7 million as part of its executive management transition. The Company recorded compensation expense of approximately $2.4 million, $1.8 million and $5.6 million in general and administrative expenses for the years ended December 31, 2012, 2011 and 2010, respectively, inclusive of discretionary contributions. During the years ended December 31, 2012 and 2011, the Company paid approximately $6.7 million and $5.5 million, respectively, to select participants of the plan. There were no payments to participants of this plan in 2010.

The net deferred tax assets reflect management’s estimate of the amount that will be realized from future profitability and the reversal of taxable temporary differences that can be predicted with reasonable certainty. A valuation allowance is recognized if it is more likely than not that at least some portion of any deferred tax asset will not be realized.

Net deferred tax liabilities were classified in the consolidated balance sheet as of December 31, 2012 and 2011 as follows (in thousands):



	2012	2011

Deferred tax assets:
Current deferred income taxes	$ 34,120	$ -

Deferred tax liabilities:
Current deferred income taxes	-	(831)
Non-current deferred income taxes	(745,144)	(297,458)


Net deferred tax liability	$ (711,024)	$ (298,289)

As of December 31, 2012, the Company had approximately $1.6 million in net operating loss carryforwards, which are available to reduce future taxable income. The expiration dates for utilization of the loss carryforwards are 2020 through 2026. Utilization of $0.5 million of the net operating loss carryforwards will be subject to the annual limitations due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended. As of December 31, 2012, the Company also has various state net operating loss carryforwards with expiration dates from 2014 to 2026. A deferred tax asset of $10.9 million reflects the expected future tax benefit for the state loss carryforwards.

The Company has not provided U.S. income tax expense on earnings of its foreign subsidiaries, since the Company has reinvested or expects to reinvest outside the U.S. the undistributed earnings indefinitely. As of December 31, 2012, the undistributed earnings of the Company’s foreign subsidiaries were approximately $176 million. If these earnings are repatriated to the U.S. in the future, additional tax provisions may be required. It is not practicable to estimate the amount of taxes that might be payable on such undistributed earnings.

The Company files income tax returns in the U.S., including federal and various state filings, and certain foreign jurisdictions. The number of years that are open under the statute of limitations and subject to audit varies depending on the tax jurisdiction. The Company remains subject to U.S. federal tax examinations for years after 2008.

The Company had approximately $26.4 million, $21.7 million and $24.8 million of unrecorded tax benefits as of December 31, 2012, 2011 and 2010, respectively, all of which would impact the Company’s effective tax rate if recognized.

The activity in unrecognized tax benefits as of December 31, 2012, 2011 and 2010 is as follows (in thousands):



	2012	2011	2010
Unrecognized tax benefits,
December 31, 2011, 2010 and 2009, respectively	$ 21,692	$ 24,760	$ 11,013

Additions based on tax positions related to prior years	6,873	871	16,607
Reductions based on tax positions related to prior years	(2,166)	(3,939)	(2,896)

Unrecognized tax benefits,
December 31, 2012, 2011 and 2010, respectively	$ 26,399	$ 21,692	$ 24,760

Segment Information

Segment Information [Abstract]

Segment Information

(11) Segment Information

Business Segments

During the fourth quarter of 2012, the Company revised the internal reporting structure that is used by the chief operating decision maker in determining how to allocate the Company’s resources and, as a result, divided the Subsea and Well Enhancement segment into three segments that better reflect the Company’s product and service offerings throughout the life cycle of a well: Onshore Completion and Workover Services, Production Services, and Subsea and Technical Solutions. The Drilling Products and Services segment remains unchanged. Accordingly, all prior period segment disclosures have been recast to reflect this change in reporting structure.

The Drilling Products and Services segment rents and sells bottom hole assemblies, premium drill pipe, tubulars and specialized equipment for use with onshore and offshore oil and gas well drilling, completion, production and workover activities. It also provides on-site accommodations and bolting and machining services. The Onshore Completion and Workover Services segment provides pressure pumping services used to complete and stimulate production in new oil and gas wells, fluid handling services and well servicing rigs that provide a variety of well completion, workover and maintenance services. The Production Services segment provides intervention services such as coiled tubing, cased hole and mechanical wireline, hydraulic workover and snubbing, production testing and optimization, and remedial pumping services. It also provides specialized pressure control tools used to manage and control pressure throughout the life of a well. The Subsea and Technical Solutions segment provides services typically requiring specialized engineering, manufacturing or project planning, including integrated subsea services and engineering services, well control services, well containment systems, stimulation and sand control services and well plug and abandonment services. It also includes production handling arrangements and the production and sale of oil and gas.

The accounting policies of the reportable segments are the same as those described in note 1 of these notes to the consolidated financial statements. The Company evaluates the performance of its operating segments based on operating profits or losses. Segment revenues reflect direct sales of products and services for that segment, and each segment records direct expenses related to its employees and its operations. Identifiable assets are primarily those assets directly used in the operations of each segment.

Summarized financial information for the Company’s segments for the years ended December 31, 2012, 2011 and 2010 is shown in the following tables (in thousands):

Guarantee	12 Months Ended
Guarantee	Dec. 31, 2012
Guarantee [Abstract]
Guarantee	(12) Guarantee In accordance with authoritative guidance related to guarantees, the Company has assigned an estimated value of $2.6 million as of December 31, 2012 and 2011, which is reflected in other long-term liabilities, related to decommissioning activities in connection with oil and gas properties acquired by SPN Resources prior to its sale to Dynamic Offshore. These properties are currently owned and operated by subsidiaries of SandRidge. The Company believes that the likelihood of being required to perform these guarantees is remote. In the unlikely event of default on any remaining decommissioning liabilities, the total maximum potential obligation under these guarantees is estimated to be approximately $125.8 million, net of the contractual right to receive payments from third parties, which is approximately $24.6 million, as of December 31, 2012. The total maximum potential obligation will decrease over time as the underlying obligations are fulfilled.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	(13) Commitments and Contingencies The Company’s wholly owned subsidiary, Hallin Marine, is the lessee of a dynamically positioned subsea vessel under a capital lease expiring in 2019 with a two year renewal option. Hallin Marine owns a 5% equity interest in the entity that owns this leased asset. The lessor’s debt is non-recourse to the Company. The amount of the asset and liability under this capital lease is recorded at the present value of the lease payments. The vessel’s gross asset value under the capital lease was approximately $37.6 million at inception and accumulated depreciation through December 31, 2012 and 2011 was approximately $12.2 million and $8.0 million, respectively. As of December 31, 2012 and 2011, the Company had approximately $25.6 million and $29.5 million, respectively, included in other long-term liabilities, and approximately $3.9 million and $3.6 million, respectively, included in accounts payable related to the obligations under this capital lease. The future minimum lease payments under this capital lease are approximately $3.9 million, $4.2 million, $4.6 million, $5.0 million and $5.4 million for the years ending December 31, 2013, 2014, 2015, 2016 and 2017, respectively, exclusive of interest at an annual rate of 8.5%. For the years ended December 31, 2012, 2011 and 2010, the Company recorded interest expense of approximately $2.7 million, $3.0 million, and $3.0 million respectively, in connection with this capital lease. The Company leases many of its office, service and assembly facilities under operating leases. In addition, the Company also leases certain assets used in providing services under operating leases. The leases expire at various dates over an extended period of time. Total rent expense was approximately $26.3 million, $18.3 million and $15.1 million in the years ended December 31, 2012, 2011 and 2010, respectively. Future minimum lease payments under non-cancelable leases for the five years ending December 31, 2013 through 2017 and thereafter are as follows: $61.9 million, $41.1 million, $26.0 million, $17.8 million, $10.9 million and $21.3 million, respectively. Due to the nature of the Company’s business, the Company is involved, from time to time, in routine litigation or subject to disputes or claims regarding its business activities. Legal costs related to these matters are expensed as incurred. In management’s opinion, none of the pending litigation, disputes or claims is expected to have a material adverse effect on the Company’s financial condition, results of operations or liquidity.

Available-for-sale securities is comprised of approximately 1.4 million shares of SandRidge common stock that the Company received as partial consideration for its 10% interest in Dynamic Offshore. The securities are reported at fair value based on the stock’s closing price as reported on the New York Stock Exchange (see note 6).

The Company’s non-qualified deferred compensation plans allow officers, certain highly compensated employees and non-employee directors to defer receipt of a portion of their compensation and contribute such amounts to one or more hypothetical investment funds (see note 9). The Company entered into separate trust agreements, subject to general creditors, to segregate assets of each plan and reports the accounts of the trusts in its consolidated financial statements. These investments are reported at fair value based on unadjusted quoted prices in active markets for identifiable assets and observable inputs for similar assets and liabilities, which represent Levels 1 and 2, respectively, in the fair value hierarchy.

In April 2012, the Company entered into an interest rate swap agreement related to its fixed rate debt maturing in December 2021 for a notional amount of $100 million, whereby the Company is entitled to receive semi-annual interest payments at a fixed rate of 7 1/8% per annum and is obligated to make semi-annual interest payments at a floating rate, adjusted every 90 days, based on LIBOR plus a fixed margin. The swap agreement, scheduled to terminate on December 15, 2021, is designated as a fair value hedge of a portion of the 7 1/8% unsecured senior notes, as the derivative has been tested to be highly effective in offsetting changes in the fair value of the underlying note. As this derivative is classified as a fair value hedge, the changes in the fair value of the derivative are offset against the changes in the fair value of the underlying note in interest expense, net (see note 15). The Company previously had an interest rate swap agreement for a notional amount of $150 million related to its fixed rate debt maturing in June 2014 that was designated as a fair value hedge. In February 2012, the Company sold this interest rate swap to the counterparty for approximately $1.2 million.

Included in current liabilities is $9.9 million of contingent consideration related to Complete’s acquisition of a remedial pumping and cementing company in 2011, and to the acquisition of a wireline and well testing company in 2012. The fair value of the contingent consideration was determined using a probability-weighted discounted cash flow approach at the acquisition and reporting date. The approach is based on significant inputs that are not observable in the market, which are referred to as Level 3 inputs. The fair value is based on the acquired companies reaching specific performance metrics. During the year ended December 31, 2012, the Company recorded additional purchase consideration of approximately $2.0 million related to its acquisition of the wireline and well testing company as certain performance metrics exceeded original projections. This additional consideration was recorded in general and administrative expenses in the consolidated statements of income. The following table summarizes the activity recorded using fair value of Level 3 liabilities for the year ended December 31, 2012 (in thousands):



Beginning balance as of December 31, 2011	$ -
Additions related to acquisitions	10,663
Settlements	(3,000)
Losses included in earnings attributable
to additional consideration	2,227

Beginning balance as of December 31, 2012	9,890

In accordance with authoritative guidance, non-financial assets and non-financial liabilities are remeasured at fair value on a non-recurring basis. During the year ended December 31, 2011, the Company wrote off approximately $46.1 million of certain long-lived assets to approximate the indicated fair value of the liftboats from the purchasers. During the year ended December 31, 2010, the Company wrote off approximately $32.0 million of long-lived liftboat components primarily related to the two partially completed liftboats. The write offs related to liftboats in both 2011 and 2010 are included in discontinued operations in the consolidated statements of income for each respective period.

The following tables reflects the fair value measurements used in testing the impairment of long-lived assets during the years ended December 31, 2011 and 2010 (in thousands):



		Fair Value Measurements at Reporting Date Using

	December 31, 2011	(Level 1)	(Level 2)	(Level 3)	Total Losses

Derivative Financial Instruments

Dec. 31, 2012

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

(15) Derivative Financial Instruments

From time to time, the Company may employ interest rate swaps in an attempt to achieve a more balanced debt portfolio. The Company does not use derivative financial instruments for trading or speculative purposes.

In April 2012, the Company entered into an interest rate swap for a notional amount of $100 million related to its fixed rate debt maturing in December 2021. This transaction is designated as a fair value hedge since the swap hedges against the change in fair value of fixed rate debt resulting from changes in interest rates. The Company recorded a derivative asset of $1.3 million within intangible and other long term assets in the consolidated balance sheet as of December 31, 2012. The change in fair value of the interest rate swap is included in the adjustments to reconcile net income to net cash provided by operating activities in the consolidated statement of cash flows.

The Company had an interest rate swap agreement for a notional amount of $150 million related to its fixed rate debt maturing in June 2014. This transaction was designated as a fair value hedge since the swap hedged against the change in fair value of fixed rate debt resulting from changes in interest rates. The Company recorded a derivative asset of $1.9 million within intangible and other long-term assets in the consolidated balance sheet as of December 31, 2011. In February 2012, the Company sold this interest rate swap to the counterparty for $1.2 million.

The location and effect of the derivative instrument on the consolidated statement of income for the years ended December 31, 2012, 2011 and 2010, presented on a pre-tax basis, is as follows (in thousands):



		Amount of (gain) loss recognized in the year ended December 31,

	Location of (gain) loss recognized	2012	2011	2010

Interest rate swap	Interest expense, net of
	amounts capitalized	$ (3,632)	$ 793	$ (1,742)
Hedged item - debt	Interest expense, net
	amounts capitalized	2,346	(2,536)	1,581
		$ (1,286)	$ (1,743)	$ (161)

For the years ended December 31, 2012, 2011 and 2010, approximately $1.3 million, $1.7 million and $0.2 million, respectively, of interest income was related to the ineffectiveness associated with these fair value hedges. Hedge ineffectiveness represents the difference between the changes in fair value of the derivative instruments and the changes in fair value of the fixed rate debt attributable to changes in the benchmark interest rate.

(19) Supplementary Oil and Natural Gas Disclosures (Unaudited)

On January 31, 2010, Wild Well acquired 100% ownership of Shell Offshore, Inc.’s Gulf of Mexico Bullwinkle platform and its related assets and assumed the related decommissioning obligation. Immediately after Wild Well acquired these assets, it conveyed an undivided 49% interest in these assets and the related well plugging and abandonment obligations to Dynamic Offshore, which operates these assets. The Company also had an interest in oil and gas operations through its equity-method investment in Dynamic Offshore (see note 7).

In January 2010, the Financial Accounting Standards Board issued an update to the authoritative guidance related to oil and gas reserve estimation and disclosures that expands the definition of oil- and gas-producing activities and requires disclosures of reserve quantities and standardized measure of cash flows for those companies that have significant oil- and gas-producing activities. For the years ended December 31, 2010 and 2011, the Company was deemed to have significant oil and gas activities. For the year ended December 31, 2012, those activities are no longer considered significant.

The Company’s December 31, 2011 estimates of proved reserves are based on reserve reports prepared by Netherland, Sewell & Associates, Inc., independent petroleum engineers. The Company’s December 31, 2010 estimates of proved reserves were based on reserve reports prepared by DeGoyler and MacNaughton and Netherland, Sewell & Associates Inc. Users of this information should be aware that the process of estimating quantities of “proved”, “proved developed” and “proved undeveloped” natural gas and crude oil reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. This data may also change substantially over time as a result of multiple factors including, but not limited to, additional development activity, evolving production history and continual reassessment of the viability of production under varying economic conditions. Consequently, material revisions to existing reserve estimates occur from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the significance of the subjective decisions required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures. Proved reserves are estimated quantities of natural gas, crude oil and condensate that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Proved undeveloped reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for completion.

The Company’s consolidated oil and gas operations, as well as its share of equity-method investment are in the Gulf of Mexico. The Company’s consolidated entity’s average sales price was $108.79 per barrel of oil and $3.45 per mcf of gas in 2011 and $77.04 per barrel of oil and $5.00 per mcf of gas in 2010. Average production costs were $12.51 and $19.99 per barrel of oil equivalent in years ended December 31, 2011 and 2010, respectively. The Company’s share of its equity-method investment’s average sales price was $113.28 per barrel of oil and $4.40 per mcf of gas in 2011 and $79.21 per barrel of oil and $4.78 per mcf of gas in 2010. Average production costs were $26.30 and $25.35 per barrel of oil equivalent in 2011 and 2010, respectively.

Standardized Measure of Discounted Future Net Cash Flows Relating to Reserves

The following information has been developed utilizing procedures prescribed by authoritative guidance related to oil and gas activities. It may be useful for certain comparative purposes, but should not be solely relied upon in evaluating the Company or its performance. Further, information contained in the following table should not be considered as representative of realistic assessments of future cash flows, nor should the standardized measure of discounted future net cash flows be viewed as representative of the current value of the Company.

The Company believes that the following factors should be taken into account in reviewing this information: (1) future costs and selling prices will likely differ from those required to be used in these calculations; (2) due to future market conditions and governmental regulations, actual rates of production achieved in future years may vary significantly from the rate of production assumed in the calculations; (3) selection of a 10% discount rate is arbitrary and may not be reasonable as a measure of the relative risk inherent in realizing future net oil and gas revenues; and (4) future net revenues may be subject to different rates of income taxation.

Under the standardized measure, future cash inflows were estimated by applying period-end oil and natural gas prices adjusted for differentials. Future cash inflows were reduced by estimated future development, abandonment and production costs based on period-end costs in order to arrive at net cash flow before tax. Future income tax expense has been computed by applying period-end statutory tax rates to aggregate future net cash flows, reduced by the tax basis of the properties involved and tax carryforwards. Use of a 10% discount rate is required by authoritative guidance related to oil and gas activities.

The standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves at December 31, 2011 and 2010 is as follows (in thousands):



			Company's Share of
	Consolidated		Equity-Method Investments
	2011	2010	2011	2010
Future cash inflows	$ 701,170	$ 486,199	$ 414,246	$ 356,126
