Summary of Significant Accounting Policies (Policies) [Abstract]  
Principles of Consolidation
 
The consolidated financial statements of Quanta include the accounts of Quanta Services, Inc. and its wholly owned subsidiaries, which are also referred to as its operating units. The consolidated financial statements also include the accounts of certain of Quanta’s investments in joint ventures, which are either consolidated or partially consolidated, as discussed in the following summary of significant accounting policies. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, references to Quanta include Quanta and its consolidated subsidiaries.
Interim Condensed Consolidated Financial Information
 
These unaudited condensed consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted pursuant to those rules and regulations. Quanta believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim consolidated financial statements have been included. The results of operations for the interim periods are not necessarily indicative of the results for the entire fiscal year. The results of Quanta have historically been subject to significant seasonal fluctuations.
 
Quanta recommends that these unaudited condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and notes thereto of Quanta and its subsidiaries included in Quanta’s Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on March 1, 2011.
 
Use of Estimates and Assumptions
 
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the financial statements are published and the reported amount of revenues and expenses recognized during the periods presented. Quanta reviews all significant estimates affecting its consolidated financial statements on a recurring basis and records the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on Quanta’s beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. Estimates are primarily used in Quanta’s assessment of the allowance for doubtful accounts, valuation of inventory, useful lives of assets, fair value assumptions in analyzing goodwill, other intangibles and long-lived asset impairments, purchase price allocations, liabilities for self-insured and other claims, revenue recognition for construction contracts and fiber optic licensing, share-based compensation, operating results of reportable segments, provision (benefit) for income taxes and calculation of uncertain tax positions.
Cash and Cash Equivalents
 
Quanta had cash and cash equivalents of $380.4 million and $539.2 million as of June 30, 2011 and December 31, 2010. Cash consisting of interest-bearing demand deposits is carried at cost, which approximates fair value. Quanta considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents, which are carried at fair value. At June 30, 2011 and December 31, 2010, cash equivalents were $318.2 million and $460.8 million, which consisted primarily of money market mutual funds and investment grade commercial paper and are discussed further in “Fair Value Measurements” below. As of June 30, 2011 and December 31, 2010, cash and cash equivalents held in domestic bank accounts was approximately $363.7 million and $509.6 million, and cash and cash equivalents held in foreign bank accounts was approximately $16.7 million and $29.6 million.
Current and Long-term Accounts and Notes Receivable and Allowance for Doubtful Accounts
 
Quanta provides an allowance for doubtful accounts when collection of an account or note receivable is considered doubtful, and receivables are written off against the allowance when deemed uncollectible. Inherent in the assessment of the allowance for doubtful accounts are certain judgments and estimates including, among others, the customer’s access to capital, the customer’s willingness or ability to pay, general economic and market conditions and the ongoing relationship with the customer. Quanta considers accounts receivable delinquent after 30 days but does not generally include delinquent accounts in its analysis of the allowance for doubtful accounts unless the accounts receivable have been outstanding for at least 90 days. In addition to balances that have been outstanding for 90 days or more, Quanta also includes accounts receivable in its analysis of the allowance for doubtful accounts if they relate to customers in bankruptcy or with other known difficulties. Under certain circumstances such as foreclosures or negotiated settlements, Quanta may take title to the underlying assets in lieu of cash in settlement of receivables. Material changes in Quanta’s customers’ business or cash flows, which may be impacted by negative economic and market conditions, could affect its ability to collect amounts due from them. As of June 30, 2011 and December 31, 2010, Quanta had total allowances for doubtful accounts of approximately $7.3 million, of which approximately $6.1 million was included as a reduction of net current accounts receivable. Should customers experience financial difficulties or file for bankruptcy, or should anticipated recoveries relating to receivables in existing bankruptcies or other workout situations fail to materialize, Quanta could experience reduced cash flows and losses in excess of current allowances provided.
 
The balances billed but not paid by customers pursuant to retainage provisions in certain contracts will be due upon completion of the contracts and acceptance by the customer. Based on Quanta’s experience with similar contracts in recent years, the majority of the retention balances at each balance sheet date will be collected within the next twelve months. Current retainage balances as of June 30, 2011 and December 31, 2010 were approximately $103.3 million and $119.4 million and are included in accounts receivable. Retainage balances with settlement dates beyond the next twelve months are included in other assets, net, and as of June 30, 2011 and December 31, 2010 were $15.5 million and $8.0 million.
 
Within accounts receivable, Quanta recognizes unbilled receivables in circumstances such as when revenues have been earned and recorded but the amount cannot be billed under the terms of the contract until a later date; costs have been incurred but are yet to be billed under cost-reimbursement type contracts; or amounts arise from routine lags in billing (for example, work completed one month but not billed until the next month). These balances do not include revenues accrued for work performed under fixed-price contracts as these amounts are recorded as costs and estimated earnings in excess of billings on uncompleted contracts. At June 30, 2011 and December 31, 2010, the balances of unbilled receivables included in accounts receivable were approximately $152.9 million and $103.5 million.
Goodwill and Other Intangibles
 
Quanta has recorded goodwill in connection with its acquisitions. Goodwill is subject to an annual assessment for impairment using a two-step fair value-based test, which Quanta performs at the operating unit level. Each of Quanta’s operating units is organized into one of three internal divisions, which are closely aligned with Quanta’s reportable segments, based on the predominant type of work performed by the operating unit at the point in time the divisional designation is made. Because separate measures of assets and cash flows are not produced or utilized by management to evaluate segment performance, Quanta’s impairment assessments of its goodwill do not include any consideration of assets and cash flows by reportable segment. As a result, Quanta has determined that its individual operating units represent its reporting units for the purpose of assessing goodwill impairments.
 
Quanta’s goodwill impairment assessment is performed annually at year-end, or more frequently if events or circumstances exist which indicate that goodwill may be impaired. For instance, a decrease in Quanta’s market capitalization below book value, a significant change in business climate or a loss of a significant customer, among other things, may trigger the need for interim impairment testing of goodwill associated with one or all of its reporting units. The first step of the two-step fair value-based test involves comparing the fair value of each of Quanta’s reporting units with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step is performed. The second step compares the carrying amount of the reporting unit’s goodwill to the implied fair value of its goodwill. If the implied fair value of goodwill is less than the carrying amount, an impairment loss would be recorded as a reduction to goodwill with a corresponding charge to operating expense.
 
Quanta determines the fair value of its reporting units using a weighted combination of the discounted cash flow, market multiple and market capitalization valuation approaches, with heavier weighting on the discounted cash flow method, as in management’s opinion, this method currently results in the most accurate calculation of a reporting unit’s fair value. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, operating margins, discount rates, weighted average costs of capital and future market conditions, among others. Quanta believes the estimates and assumptions used in its impairment assessments are reasonable and based on available market information, but variations in any of the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment is indicated.
 
Under the discounted cash flow method, Quanta determines fair value based on the estimated future cash flows of each reporting unit, discounted to present value using risk-adjusted industry discount rates, which reflect the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. Cash flow projections are derived from budgeted amounts and operating forecasts (typically a three-year model) plus an estimate of later period cash flows, all of which are evaluated by management. Subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonably likely to occur along with a terminal value derived from the reporting unit’s earnings before interest, taxes, depreciation and amortization (EBITDA). The EBITDA multiples for each reporting unit are based on trailing twelve-month comparable industry data.
 
Under the market multiple and market capitalization approaches, Quanta determines the estimated fair value of each of its reporting units by applying transaction multiples to each reporting unit’s projected EBITDA and then averaging that estimate with similar historical calculations using either a one, two or three year average. For the market capitalization approach, Quanta adds a reasonable control premium, which is estimated as the premium that would be received in a sale of the reporting unit in an orderly transaction between market participants.
 
For recently acquired reporting units, a step one impairment test may indicate an implied fair value that is substantially similar to the reporting unit’s carrying value. Such similarities in value are generally an indication that management’s estimates of future cash flows associated with the recently acquired reporting unit remain relatively consistent with the assumptions that were used to derive its initial fair value. During the fourth quarter of 2010, a goodwill impairment analysis was performed for each of Quanta’s operating units, which indicated that the implied fair value of each of Quanta’s operating units was substantially in excess of carrying value. Following the analysis, management concluded that no impairment was indicated at any operating unit. As discussed generally above, when evaluating the 2010 step one impairment test results, management considered many factors in determining whether or not an impairment of goodwill for any reporting unit was reasonably likely to occur in future periods, including future market conditions and the economic environment in which Quanta’s reporting units were operating. Additionally, management considered the sensitivity of its fair value estimates to changes in certain valuation assumptions and after giving consideration to at least a 10% decrease in the fair value of each of Quanta’s reporting units, the results of our assessment at December 31, 2010 did not change. However, circumstances such as market declines, unfavorable economic conditions, the loss of a major customer or other factors could impact the valuation of goodwill in future periods.
 
Quanta’s intangible assets include customer relationships, backlog, trade names, non-compete agreements and patented rights and developed technology. The value of customer relationships is estimated using the value-in-use concept utilizing the income approach, specifically the excess earnings method. The excess earnings analysis consists of discounting to present value the projected cash flows attributable to the customer relationships, with consideration given to customer contract renewals, the importance or lack thereof of existing customer relationships to Quanta’s business plan, income taxes and required rates of return. Quanta values backlog based upon the contractual nature of the backlog within each service line, using the income approach to discount back to present value the cash flows attributable to the backlog. The value of trade names is estimated using the relief-from-royalty method of the income approach. This approach is based on the assumption that in lieu of ownership, a company would be willing to pay a royalty in order to exploit the related benefits of this intangible asset.
 
Quanta amortizes intangible assets based upon the estimated consumption of the economic benefits of each intangible asset or on a straight-line basis if the pattern of economic benefits consumption cannot otherwise be reliably estimated. Intangible assets subject to amortization are reviewed for impairment and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. For instance, a significant change in business climate or a loss of a significant customer, among other things, may trigger the need for interim impairment testing of intangible assets. An impairment loss would be recognized if the carrying amount of an intangible asset is not recoverable and its carrying amount exceeds its fair value.
Investments in Affiliates and Other Entities
 
In the normal course of business, Quanta enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by Quanta in either an incorporated or unincorporated entity, a general or limited partnership, a contractual joint venture, or some other form of equity participation. These investments may also include Quanta’s participation in different finance structures such as the extension of loans to project specific entities, the acquisition of convertible notes issued by project specific entities, or other strategic financing arrangements. Quanta determines whether such investments involve a variable interest entity (VIE) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if Quanta is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally meet both of the following characteristics: (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. When Quanta is deemed to be the primary beneficiary and the VIE is consolidated, the other party’s equity interest in the VIE is accounted for as a noncontrolling interest. In cases where Quanta determines it has an undivided interest in the assets, liabilities, revenues and profits of an unincorporated VIE (i.e., a general partnership interest), such amounts are consolidated on a basis proportional to Quanta’s ownership interest in the unincorporated entity.
 
Investments in minority interests in entities of which Quanta is not the primary beneficiary, but over which Quanta has the ability to exercise significant influence, are accounted for using the equity method of accounting. Quanta’s share of net income or losses from unconsolidated equity investments is included in other income (expense) in the condensed consolidated statements of operations. Equity investments are reviewed for impairment by assessing whether any decline in the fair value of the investment below the carrying value is other than temporary. In making this determination, factors such as the ability to recover the carrying amount of the investment and the inability of the investee to sustain an earnings capacity are evaluated in determining whether a loss in value should be recognized. Any impairment losses would be recognized in other expense. Equity method investments are carried at original cost and are included in other assets, net in the condensed consolidated balance sheet and are adjusted for Quanta’s proportionate share of the investees’ income, losses and distributions.
 
On June 22, 2011, Quanta acquired an equity ownership interest of approximately 39% in Howard Midstream Energy Partners, LLC (HEP) for an initial capital contribution of $35.0 million. HEP is engaged in the business of owning, operating and constructing midstream plant and pipeline assets in the oil and gas industry. HEP commenced operations in June 2011 with the acquisitions of Texas Pipeline LLC, a pipeline operator in the Eagle Ford shale region of South Texas, and Bottom Line Services, LLC, a construction services company. Quanta accounts for this investment using the equity method of accounting.
 
During the second quarter of 2011, Quanta agreed to loan up to $4.0 million to the indirect parent of NJ Oak Solar, LLC (NJ Oak Solar). The loan proceeds, together with other financing and equity funds, will be used for NJ Oak Solar’s construction of a 10 MW solar power generation facility in New Jersey. The construction of the facility, which began in the second quarter of 2011, will be performed by Quanta.
Revenue Recognition
 
Infrastructure Services — Through its Electric Power Infrastructure Services, Natural Gas and Pipeline Infrastructure Services and Telecommunications Infrastructure Services segments, Quanta designs, installs and maintains networks for customers in the electric power, natural gas, oil and telecommunications industries. These services may be provided pursuant to master service agreements, repair and maintenance contracts and fixed price and non-fixed price installation contracts. Pricing under contracts may be competitive unit price, cost-plus/hourly (or time and materials basis) or fixed price (or lump sum basis), and the final terms and prices of these contracts are frequently negotiated with the customer. Under unit-based contracts, the utilization of an output-based measurement is appropriate for revenue recognition. Under these contracts, Quanta recognizes revenue as units are completed based on pricing established between Quanta and the customer for each unit of delivery, which best reflects the pattern in which the obligation to the customer is fulfilled. Under cost-plus/hourly and time and materials type contracts, Quanta recognizes revenue on an input basis, as labor hours are incurred and services are performed.
 
Revenues from fixed price contracts are recognized using the percentage-of-completion method, measured by the percentage of costs incurred to date to total estimated costs for each contract. These contracts provide for a fixed amount of revenues for the entire project. Such contracts provide that the customer accept completion of progress to date and compensate Quanta for services rendered, which may be measured in terms of units installed, hours expended or some other measure of progress. Contract costs include all direct materials, labor and subcontract costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Much of the materials associated with Quanta’s work are owner-furnished and are therefore not included in contract revenues and costs. The cost estimation process is based on the professional knowledge and experience of Quanta’s engineers, project managers and financial professionals. Changes in job performance, job conditions and final contract settlements are factors that influence management’s assessment of total contract value and the total estimated costs to complete those contracts and therefore, Quanta’s profit recognition. Changes in these factors may result in revisions to costs and income, and their effects are recognized in the period in which the revisions are determined. Provisions for losses on uncompleted contracts are made in the period in which such losses are determined to be probable and the amount can be reasonably estimated.
 
Quanta may incur costs subject to change orders, whether approved or unapproved by the customer, and/or claims related to certain contracts. Quanta determines the probability that such costs will be recovered based upon evidence such as past practices with the customer, specific discussions or preliminary negotiations with the customer or verbal approvals. Quanta treats items as a cost of contract performance in the period incurred if it is not probable that the costs will be recovered or will recognize revenue if it is probable that the contract price will be adjusted and can be reliably estimated. As of June 30, 2011 and December 31, 2010, Quanta had approximately $48.1 million and $83.1 million of change orders and/or claims that had been included as contract price adjustments on certain contracts which were in the process of being negotiated in the normal course of business.
 
The current asset “Costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed for fixed price contracts. The current liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized for fixed price contracts.
 
Fiber Optic Licensing — The Fiber Optic Licensing segment constructs and licenses the right to use fiber optic telecommunications facilities to its customers pursuant to licensing agreements, typically with terms from five to twenty-five years, inclusive of certain renewal options. Under those agreements, customers are provided the right to use a portion of the capacity of a fiber optic facility, with the facility owned and maintained by Quanta. Revenues, including any initial fees or advance billings, are recognized ratably over the expected length of the agreements, including probable renewal periods. As of June 30, 2011 and December 31, 2010, initial fees and advance billings on these licensing agreements not yet recorded in revenue were $47.0 million and $44.4 million and are recognized as deferred revenue, with $37.6 million and $34.7 million considered to be long-term and included in other non-current liabilities.
Income Taxes
 
Quanta follows the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled.
 
Quanta regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain. The estimation of required valuation allowances includes estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Quanta considers projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from these estimates, Quanta may not realize deferred tax assets to the extent estimated.
 
Quanta records reserves for expected tax consequences of uncertain positions assuming that the taxing authorities have full knowledge of the position and all relevant facts. As of June 30, 2011, the total amount of unrecognized tax benefits relating to uncertain tax positions was $55.9 million, an increase from December 31, 2010 of $5.3 million, which primarily relates to tax positions expected to be taken for 2011. Quanta recognized $1.0 million of interest expense and penalties in the provision for income taxes for both of the quarters ended June 30, 2011 and 2010 and recognized $1.8 million and $2.0 million of interest expense and penalties in the provision for income taxes for the six months ended June 30, 2011 and 2010. Quanta believes that it is reasonably possible that within the next 12 months unrecognized tax benefits may decrease by up to $8.7 million due to the expiration of certain statutes of limitations.
 
The income tax laws and regulations are voluminous and are often ambiguous. As such, Quanta is required to make many subjective assumptions and judgments regarding its tax positions that could materially affect amounts recognized in its future consolidated balance sheets and statements of operations.
Stock-Based Compensation
 
Quanta recognizes compensation expense for all stock-based compensation based on the fair value of the awards granted, net of estimated forfeitures, at the date of grant. The fair value of restricted stock awards is determined based on the number of shares granted and the closing price of Quanta’s common stock on the date of grant. An estimate of future forfeitures is required in determining the period expense. Quanta uses historical data to estimate the forfeiture rate; however, these estimates are subject to change and may impact the value that will ultimately be realized as compensation expense. The resulting compensation expense from discretionary awards is recognized on a straight-line basis over the requisite service period, which is generally the vesting period, while compensation expense from performance-based awards is recognized using the graded vesting method over the requisite service period. The cash flows resulting from the tax deductions in excess of the compensation expense recognized for restricted stock and stock options (excess tax benefit) are classified as financing cash flows.
Functional Currency and Translation of Financial Statements
 
The U.S. dollar is the functional currency for the majority of Quanta’s operations. However, Quanta has foreign operating units in Canada, for which Quanta considers the Canadian dollar to be the functional currency. Generally, the currency in which the operating unit transacts a majority of its transactions, including billings, financing, payroll and other expenditures, would be considered the functional currency, but any dependency upon the parent company and the nature of the operating unit’s operations must also be considered. Under the relevant accounting guidance, the treatment of these translation gains or losses is dependent upon management’s determination of the functional currency of each operating unit, which involves consideration of all relevant economic facts and circumstances affecting the operating unit. In preparing the consolidated financial statements, Quanta translates the financial statements of its foreign operating units from their functional currency into U.S. dollars. Statements of operations and cash flows are translated at average monthly rates, while balance sheets are translated at the month-end exchange rates. The translation of the balance sheets at the month-end exchange rates results in translation gains or losses. If transactions are denominated in the operating units’ functional currency, the translation gains and losses are included as a separate component of equity under the caption “Accumulated other comprehensive income.” If transactions are not denominated in the operating units’ functional currency, the translation gains and losses are included within the statement of operations.
Comprehensive Income
 
Comprehensive income includes all changes in equity during a period except those resulting from investments by and distributions to stockholders. Quanta records other comprehensive income (loss), net of tax, for the foreign currency translation adjustment related to its foreign operations and for changes in fair value of its derivative contracts that are classified as cash flow hedges, as applicable.
Fair Value Measurements
 
The carrying values of cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term nature of these instruments. For disclosure purposes, qualifying assets and liabilities are categorized into three broad levels based on the priority of the inputs used to determine their fair values. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). All of Quanta’s cash equivalents are categorized as Level 1 assets at June 30, 2011 and December 31, 2010, as all values are based on unadjusted quoted prices for identical assets in an active market that Quanta has the ability to access.
 
In connection with Quanta’s acquisitions, identifiable intangible assets acquired included goodwill, backlog, customer relationships, trade names and covenants not-to-compete. Quanta utilizes the fair value premise as the primary basis for its valuation procedures, which is a market based approach to determining the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Quanta periodically engages the services of an independent valuation firm to assist management with this valuation process, which includes assistance with the selection of appropriate valuation methodologies and the development of market-based valuation assumptions. Based on these considerations, management utilizes various valuation methods, including an income approach, a market approach and a cost approach, to determine the fair value of intangible assets acquired based on the appropriateness of each method in relation to the type of asset being valued. The assumptions used in these valuation methods are analyzed and compared, where possible, to available market data, such as industry-based weighted average costs of capital and discount rates, trade name royalty rates, public company valuation multiples and recent market acquisition multiples. The level of inputs used for these fair value measurements is the lowest level (Level 3). Quanta believes that these valuation methods appropriately represent the methods that would be used by other market participants in determining fair value.
 
Quanta uses fair value measurements on a routine basis in its assessment of assets classified as goodwill, other intangible assets and long-lived assets held and used. In accordance with its annual impairment test during the quarter ended December 31, 2010, the carrying amounts of such assets, including goodwill, was compared to their fair values. No changes in carrying amounts resulted. The inputs used for fair value measurements for goodwill, other intangible assets and long-lived assets held and used are the lowest level (Level 3) inputs for which Quanta uses the assistance of third party specialists to develop valuation assumptions.
 
The valuation of investments in private company equity interests and financing instruments requires significant management judgment due to the absence of quoted market prices, the inherent lack of liquidity and the long-term nature of such assets. Typically, these investments are valued initially at cost. Each quarter, valuations are reviewed using available and relevant market data to determine if the carrying value of these investments should be adjusted. Such market data primarily include observations of the trading multiples of public companies considered comparable to the private companies being valued and the operating performance of the underlying portfolio company, including its historical and projected net income and its earnings before interest, taxes, depreciation and amortization (EBITDA). Valuations are adjusted to account for company-specific issues, the lack of liquidity inherent in a private investment, and the fact that comparable public companies are not identical to the companies being valued. In addition, a variety of additional factors are reviewed by management, including, but not limited to, financing and sales transactions with third parties, future expectations with respect to the particular investment, changes in market outlook and the third-party financing environment. Investments in private company equity interests and financing arrangements are included in Level 3 of the valuation hierarchy. As of June 30, 2011, the fair value of Quanta’s private equity investment in HEP accounted for under the equity method is assumed to be equal to its cost due to the investment being made just prior to quarter-end.
Adoption of New Accounting Pronouncements
 
None.
Accounting Standards Not Yet Adopted
 
In May 2011, the Financial Accounting Standards Board (FASB) issued ASU 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04), which is effective for annual reporting periods beginning after December 15, 2011. This guidance amends certain accounting and disclosure requirements related to fair value measurements. Additional disclosure requirements in the update include: (1) for Level 3 fair value measurements, quantitative information about unobservable inputs used, a description of the valuation processes used by the entity, and a qualitative discussion about the sensitivity of the measurements to changes in the unobservable inputs; (2) for an entity’s use of a nonfinancial asset that is different from the asset’s highest and best use, the reason for the difference; (3) for financial instruments not measured at fair value but for which disclosure of fair value is required, the fair value hierarchy level in which the fair value measurements were determined; and (4) the disclosure of all transfers between Level 1 and Level 2 of the fair value hierarchy. Quanta will adopt ASU 2011-04 on January 1, 2012. Quanta is currently evaluating ASU 2011-04 and has not yet determined the impact that adoption will have on its consolidated financial statements.
 
In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (ASU 2011-05), which is effective for annual reporting periods beginning after December 15, 2011. Accordingly, Quanta will adopt ASU 2011-05 on January 1, 2012. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. In addition, items of other comprehensive income that are reclassified to profit or loss are required to be presented separately on the face of the financial statements. This guidance is intended to increase the prominence of other comprehensive income in financial statements by requiring that such amounts be presented either in a single continuous statement of income and comprehensive income or separately in consecutive statements of income and comprehensive income. The adoption of ASU 2011-05 is not expected to have a material impact on Quanta’s financial position or results of operations.
Earnings Per Share Information
 
Basic earnings per share is computed using the weighted average number of common shares outstanding during the period, and diluted earnings per share is computed using the weighted average number of common shares outstanding during the period adjusted for all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be antidilutive.
Repurchase of Common Stock
 
During the second quarter of 2011, Quanta’s board of directors approved a stock repurchase program authorizing Quanta to purchase, from time to time, up to $150.0 million of its outstanding common stock. These repurchases may be made in open market transactions, in privately negotiated transactions, including block purchases, or otherwise, at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program does not obligate Quanta to acquire any specific amount of common stock and will continue until it is completed or otherwise modified or terminated by Quanta’s board of directors at any time in its sole discretion and without notice. The stock repurchase program is funded with cash on hand. During the three months ended June 30, 2011, Quanta repurchased 4,915,225 shares of its common stock under this program at a cost of $94.5 million. These shares and the related cost to acquire them were accounted for as an adjustment to the balance of treasury stock. Under Delaware corporate law, treasury stock is not entitled to vote or be counted for quorum purposes.
Segment Reporting
 
Quanta presents its operations under four reportable segments: (1) Electric Power Infrastructure Services, (2) Natural Gas and Pipeline Infrastructure Services, (3) Telecommunications Infrastructure Services and (4) Fiber Optic Licensing. This structure is generally focused on broad end-user markets for Quanta’s services. See Note 1 for additional information regarding Quanta’s reportable segments.
 
Quanta’s segment results are derived from the types of services provided across its operating units in each of the end user markets described above. Quanta’s entrepreneurial business model allows each of its operating units to serve the same or similar customers and to provide a range of services across end user markets. Quanta’s operating units are organized into one of three internal divisions, namely, the electric power division, natural gas and pipeline division and telecommunications division. These internal divisions are closely aligned with the reportable segments described above based on their operating units’ predominant type of work, with the operating units providing predominantly telecommunications and fiber optic licensing services being managed within the same internal division.
 
Reportable segment information, including revenues and operating income by type of work, is gathered from each operating unit for the purpose of evaluating segment performance in support of Quanta’s market strategies. These classifications of Quanta’s operating unit revenues by type of work for segment reporting purposes can at times require judgment on the part of management. Quanta’s operating units may perform joint infrastructure service projects for customers in multiple industries, deliver multiple types of network services under a single customer contract or provide services across industries, for example, joint trenching projects to install distribution lines for electric power, natural gas and telecommunications customers.
 
In addition, Quanta’s integrated operations and common administrative support at each of its operating units requires that certain allocations, including allocations of shared and indirect costs, such as facility costs, indirect operating expenses including depreciation, and general and administrative costs, are made to determine operating segment profitability. Corporate costs, such as payroll and benefits, employee travel expenses, facility costs, professional fees, acquisition costs and amortization related to certain intangible assets are not allocated.
