2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Basic and its wholly owned subsidiaries. Basic has no variable interest in any other organization, entity, partnership, or contract. All intercompany transactions and balances have been eliminated.

Estimates and Uncertainties

Preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Areas where critical accounting estimates are made by management include:

•

Depreciation and amortization of property and equipment and intangible assets

•

Impairment of property and equipment, goodwill and intangible assets

•

Allowance for doubtful accounts

•

Litigation and self-insured risk reserves

•

Fair value of assets acquired and liabilities assumed

•

Future cash flows

•

Stock-based compensation

•

Income taxes

•

Asset retirement obligations

Revenue Recognition

Completion and Remedial Services — Completion and remedial services consists primarily of pumping services, focused on cementing, acidizing and fracturing, nitrogen units, coiled tubing units, snubbing units, water treatment, thru-tubing and rental and fishing tools. Basic recognizes revenue when services are performed, collection of the relevant receivables is probable, persuasive evidence of an arrangement exists and the price is fixed or determinable. Basic prices completion and remedial services by the hour, day, or project depending on the type of service performed. When Basic provides multiple services to a customer, revenue is allocated to the services performed based on the fair value of the services.

Fluid Services — Fluid services consists primarily of the sale, transportation, storage and disposal of fluids used in drilling, production and maintenance of oil and natural gas wells, and well site construction and maintenance services. Basic recognizes revenue when services are performed, collection of the relevant receivables is probable, persuasive evidence of an arrangement exists and the price is fixed or determinable. Basic prices fluid services by the job, by the hour or by the quantities sold, disposed of or hauled.

Well Servicing — Well servicing consists primarily of maintenance services, workover services, completion services, plugging and abandonment services and rig manufacturing and servicing. Basic recognizes revenue when services are performed, collection of the relevant receivables is probable, persuasive evidence of an arrangement exists and the price is fixed or determinable. Basic prices well servicing by the hour or by the day of service performed. Rig manufacturing revenue is recognized when the rig is accepted by the customer, based on the completed contract method by individual rig.

Contract Drilling — Contract drilling consists primarily of drilling wells to a specified depth using drilling rigs. Basic recognizes revenues based on either a "daywork" contract, in which an agreed upon rate per day is charged to the customer, or a "footage" contract, in which an agreed upon rate is charged per the number of feet drilled.

Taxes assessed on sales transactions are presented on a net basis and are not included in revenue.

Inventories

For rental and fishing tools, inventories consisting mainly of grapples and drill bits are stated at the lower of cost or market, with cost being determined by the average cost method. Other inventories, consisting mainly of manufacturing raw materials, rig components, repair parts, drilling and completion materials and gravel, are held for use in the operations of Basic and are stated at the lower of cost or market, with cost being determined on the first-in, first-out ("FIFO") method.

Property and Equipment

Property and equipment are stated at cost or at estimated fair value at acquisition date if acquired in a business combination. Expenditures for repairs and maintenance are charged to expense as incurred and additions and improvements that significantly extend the lives of the assets are capitalized. Upon sale or other retirement of depreciable property, the cost and accumulated depreciation and amortization are removed from the related accounts and any gain or loss is reflected in operations. All property and equipment are depreciated or amortized (to the extent of estimated salvage values) on the straight-line method. The components of a well servicing rig generally require replacement or refurbishment during the well servicing rig's life and are depreciated over their estimated useful lives, which range from 3 to 15 years. The costs of the original components of a purchased or acquired well servicing rig are not maintained separately from the base rig.

Impairments

Long-lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization, are reviewed for impairment at least annually, or whenever, in management's judgment, 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 measured by a comparison of the carrying amount of such assets to estimated undiscounted future cash flows expected to be generated by the assets. Expected future cash flows and carrying values are aggregated at their lowest identifiable level. If the carrying amount of such assets exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of such assets exceeds the fair value of the assets. Assets to be disposed of would be separately presented in the consolidated balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities, if material, of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet. These assets are normally sold within a short period of time through a third party auctioneer.

Basic's goodwill and trade name intangibles are considered to have an indefinite useful economic life and are not amortized. Basic assesses impairment of its goodwill and trade name intangibles annually as of December 31 or on an interim basis if events or circumstances indicate that the fair value of the assets has decreased below the assets' carrying value. A qualitative assessment is allowed to determine if goodwill is potentially impaired. The qualitative assessment determines whether it is more likely than not that a reporting unit's fair value is less than its carrying amount. If it is more likely than not that the fair value of the reporting unit is less than the carrying amount then the two-step impairment test is performed. First, the fair value of each reporting unit is compared to its carrying value to determine whether an indication of impairment exists. If impairment is indicated, then the fair value of the reporting unit's goodwill is determined by allocating the unit's fair value to its assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The amount of impairment for goodwill is measured as the excess of its carrying value over its fair value.

Deferred Debt Costs

Basic capitalizes certain costs in connection with obtaining its borrowings, such as lender's fees and related attorney's fees. These costs are amortized to interest expense using the effective interest method.

Deferred debt costs were approximately $20.8 million net of accumulated amortization of $5.3 million, and $20.8 million net of accumulated amortization of $4.6 million at March 31, 2012 and December 31, 2011, respectively. Amortization of deferred debt costs totaled approximately $693,000 and $432,000 for the three months ended March 31, 2012 and 2011, respectively.

Basic recorded a charge of $3.9 million during the first quarter of 2011 related to the write-off of debt costs associated with its 11.625% Senior Secured Notes and $30.0 million revolving credit facility. On February 15, 2011, Basic terminated the revolving credit facility and completed the closing for an early tender for approximately $224.7 million of the Senior Secured Notes and delivered to the trustee amounts required to satisfy and discharge remaining obligations for the outstanding notes. Basic also incurred $3.2 million of deferred debt costs associated with the $165.0 million revolving credit facility entered into on February 15, 2011. Basic incurred $12.4 million of deferred debt costs associated with the issuance of the 7.75% Senior Notes due 2019.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets not subject to amortization are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Basic completes its assessment of goodwill and trade name intangible impairment as of December 31 of each year.

Basic had trade names of $1.9 million as of March 31, 2012 and $1.9 million at December 31, 2011. Trade names have an indefinite life and are tested for impairment annually.

Additions to goodwill during the three months ended March 31, 2012 were primarily due to the purchase price allocations for acquisitions completed during 2011. These purchase price allocations were preliminary and subject to change. The changes in the carrying amount of goodwill for the three months ended March 31, 2012 were as follows (in thousands):


	Completion and Remedial Services			Fluid Services		Well Servicing			Contract Drilling		Total
Balance as of December 31, 2011	$	72,369		$	4,086	$	6,116		$	—	$	82,571
Goodwill adjustments		(29	)		97		(60	)		—		8

Balance as of March 31, 2012	$	72,340		$	4,183	$	6,056		$	—	$	82,579

Basic's intangible assets subject to amortization consist of customer relationships, non-compete agreements and rig engineering plans. The gross carrying amount of customer relationships subject to amortization was $76.6 million at March 31, 2012 and $78.2 million at December 31, 2011. The gross carrying amount of non-compete agreements subject to amortization totaled approximately $7.4 million and $7.6 million at March 31, 2012 and December 31, 2011, respectively. The gross carrying amount of other intangible assets subject to amortization was $1.1 million and $1.1 million at March 31, 2012 and December 31, 2011, respectively. Accumulated amortization related to these intangible assets totaled approximately $15.3 million and $14.1 million at March 31, 2012 and December 31, 2011, respectively. Amortization expense for the three months ended March 31, 2012 and 2011 was approximately $1.7 million and $1.1 million, respectively. Other intangibles net of accumulated amortization allocated to reporting units as of March 31, 2012 were $56.9 million, $3.6 million, $4.8 million and $4.5 million for completion and remedial services, fluid services, well servicing, and contract drilling, respectively. No adjustments were made to prior periods to reflect subsequent adjustments to acquisitions due to immateriality. Customer relationships are amortized over a 15-year life, non-compete agreements are amortized over a five-year life, and rig engineering plans are amortized over a 15-year life.

Stock-Based Compensation

Basic's stock-based awards consist of stock options and restricted stock. Stock options issued are valued on the grant date using the Black-Scholes-Merton option-pricing model, and restricted stock issued is valued based on the fair value of Basic's common stock at the grant date. All stock-based awards are adjusted for an expected forfeiture rate and amortized over the vesting period.

Income Taxes

Basic recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in the period that includes the statutory enactment date. A valuation allowance for deferred tax assets is recognized when it is more likely than not that the benefit of deferred tax assets will not be realized.

The decrease in our effective tax rate from the three months ended March 31, 2011 to the three months ended March 31, 2012 was primarily due to an increased tax effect related to the early tender of our Senior Secured Notes in February 2011.

Interest charges are recorded in interest expense and penalties are recorded in income tax expense.

Concentrations of Credit Risk

Financial instruments, which potentially subject Basic to concentration of credit risk, consist primarily of temporary cash investments and trade receivables. Basic restricts investment of temporary cash investments to financial institutions with high credit standing. Basic's customer base consists primarily of multi-national and independent oil and natural gas producers. Basic performs ongoing credit evaluations of its customers but generally does not require collateral on its trade receivables. Credit risk is considered by management to be limited due to the large number of customers comprising its customer base. Basic maintains an allowance for potential credit losses on its trade receivables, and such losses have been within management's expectations.

Basic did not have any one customer that represented 10% or more of consolidated revenue during the three months ended March 31, 2012 or 2011.

Asset Retirement Obligations

Basic records the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets and capitalizes an equal amount as a cost of the asset depreciating it over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each quarter to reflect the passage of time, changes in the estimated future cash flows underlying the obligation, acquisition or construction of assets, and settlements of obligations.

Environmental

Basic is subject to extensive federal, state and local environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and may require Basic to remove or mitigate the adverse environmental effects of disposal or release of petroleum, chemicals and other substances at various sites. Environmental expenditures are expensed or capitalized depending on the future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a non-capital nature are recorded when environmental assessment and/or remediation is probable and the costs can be reasonably estimated.

Litigation and Self-Insured Risk Reserves

Basic estimates its reserves related to litigation and self-insured risks based on the facts and circumstances specific to the litigation and self-insured claims, its past experience with similar claims and the likelihood of the future event occurring. Basic maintains accruals on the consolidated balance sheets to cover self-insurance retentions (See note 6).

Recent Accounting Pronouncements

In June 2011, the FASB issued ASU No. 2011-05, "Comprehensive Income: Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 requires companies to present the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements of net income and other comprehensive income. This statement is effective for interim and annual periods beginning after December 15, 2011. Early adoption is permitted and the amendments in this update will be applied retrospectively. Basic currently does not have any items of other comprehensive income and therefore does not expect a material impact on its consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, "Intangibles — Goodwill and Other" ("ASU 2011-08"). ASU 2011-08 allows a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the two-step impairment test for that reporting unit would be performed. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 and early adoption is permitted. Basic early adopted this accounting standard update and although it has changed the process Basic uses to determine if goodwill is impaired, it has not had a material impact on Basic's consolidated financial statements.
