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 September 30, 2011 and December 31, 2010, Quanta had total allowances for doubtful accounts of approximately $7.4 million and $7.3 million, of which approximately $6.3 million and $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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The balances billed but not paid by customers pursuant to retainage provisions in certain contracts are generally due upon completion of the contracts and acceptance by the customer.

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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div>  <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta’s intangible assets include customer relationships, backlog, trade names, non-compete agreements, patented rights and developed technology, all subject to amortization, along with other intangible assets not subject to amortization. The value of customer relationships is estimated as of the date a business is acquired using the <font style="white-space: nowrap">value-in-use</font> 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 as of the date a business is acquired 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 as of the date a business is acquired 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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.

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, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest. In cases where Quanta determines that 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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.

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.

Quanta recognized interest expense and penalties in the provision for income taxes of $1.0 million and $2.8 million for the three and nine months ended September 30, 2011. Quanta recognized net benefits of $4.6 million and $2.6 million for the three and nine months ended September 30, 2010.

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. </div> <div style="margin-top: 12pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 2%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b><i><font style="font-family: 'Times New Roman', Times">Functional Currency and Translation of Financial Statements</font></i></b> </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The U.S. dollar is the functional currency for the majority of Quanta’s operations, which are primarily located within the United States. The functional currency for Quanta’s foreign operations, which are primarily located in Canada, is typically the currency of the country in which the foreign operating unit is located. Generally, the currency in which the operating unit transacts a majority of its activities, including billings, financing, payroll and other expenditures, would be considered the functional currency. Under the relevant accounting guidance, the treatment of foreign currency 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 (loss).” If transactions are not denominated in the operating units’ functional currency, the translation gains and losses are included within the statement of operations. </div> <div style="margin-top: 12pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 2%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b><i><font style="font-family: 'Times New Roman', Times">Comprehensive Income</font></i></b> </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Comprehensive income includes all changes in equity during a period except those resulting from investments by and distributions to stockholders.

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 September 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> In connection with Quanta’s acquisitions, identifiable intangible assets acquired included goodwill, backlog, customer relationships, trade names and covenants <font style="white-space: nowrap">not-to-compete.</font> 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 when a new business is acquired 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).

In accordance with its annual impairment test during the quarter ended December 31, 2010, the carrying amounts of such assets, including goodwill, were 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta also uses fair value measurements in connection with the valuation of its investments in private company equity interests and financing instruments. These valuations require 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, the initial costs of these investments are considered to represent fair market value, as such amounts are negotiated between willing market participants. On a quarterly basis, Quanta performs an evaluation of its investments to determine if an other than temporary decline in the value of each investment has occurred and whether or not the recorded amount of each investment will be realizable. If an other than temporary decline in the value of an investment occurs, a fair value analysis would be performed to determine the degree to which the investment was impaired and a corresponding charge to earnings would be recorded during the period. These types of fair market value assessments are similar to other fair value measures used by Quanta, which include the use of significant judgment and available relevant market data. Such market data may include observations of the valuation of comparable companies, risk adjusted discount rates and an evaluation of the expected performance of the underlying portfolio asset, including historical and projected levels of profitability or cash flows. In addition, a variety of additional factors will be reviewed by management, including, but not limited to, contemporaneous financing and sales transactions with third parties, 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. </div> </div>

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.

However, entities can choose to early adopt this ASU. This guidance gives entities the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step goodwill impairment test. If an entity believes that, as a result of its qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. An entity can choose to perform the qualitative assessment on none, some or all of its reporting units. An entity can also bypass the qualitative assessment for any reporting unit in any period and proceed directly to step one of the impairment test, and then resume performing the qualitative assessment in any subsequent period.

This guidance requires employers to make various disclosures for each individually significant multiemployer plan that provides pension benefits to its employees. Generally, an employer must disclose the employer’s contributions to the plan during the period and provide a description of the nature and effect of any significant changes that affect comparability of total employer contributions from period to period. Additionally, the employer should provide a description of the nature of the plan benefits, a qualitative description of the extent to which the employer could be responsible for the obligations of the plan, including benefits earned by employees during employment with another employer and other quantitative information, to the extent available, as of the most recent date available, to help users understand the financial information for each significant plan. An employer should also provide disclosures for total contributions made to all plans that are not individually significant and total contributions made to all plans. If certain quantitative information cannot be obtained without undue cost and effort, that quantitative information may be omitted, although the employer should describe what information has been omitted and why.

The pro forma combined results of operations for the three and nine months ended September 30, 2010 have also been prepared by adjusting the historical results of Quanta to include the historical results of the 2010 acquisition as if it occurred January 1, 2009 . These pro forma combined historical results were then adjusted for the following: a reduction of interest expense and interest income as a result of the repayment of outstanding indebtedness, a reduction of interest income as a result of the cash consideration paid, an increase in amortization expense due to the incremental intangible assets recorded related to the 2011 and 2010 acquisitions, an increase in depreciation expense within cost of services related to the net impact of adjusting acquired property and equipment to the acquisition date fair value and conforming depreciable lives with Quanta’s accounting policies and certain reclassifications to conform the acquired companies’ presentation to Quanta’s accounting policies. The pro forma results of operations do not include any adjustments to eliminate the impact of acquisition related costs or any cost savings or other synergies that may result from the 2011 and 2010 acquisitions. As noted above, the pro forma results of operations do not purport to be indicative of the actual results that would have been achieved by the combined company for the periods presented or that may be achieved by the combined company in the future. Revenues of approximately$12.0 million and income before income taxes of approximately $0.3 million are included in Quanta’s condensed consolidated results of operations for the three and nine months ended September 30, 2011 related to the four acquisitions which occurred during the three months ended September 30, 2011. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div>  </div>

The 3.9 million exchangeable shares of a Canadian subsidiary of Quanta that were issued pursuant to the acquisition of Valard on October 25, 2010, which are exchangeable on a <font style="white-space: nowrap">one-for-one</font> basis with Quanta common shares, are included in weighted average shares outstanding for basic and diluted earnings per share for the three and nine months ended September 30, 2011. Shares placed in escrow related to a previous acquisition are included in the computation of diluted earnings per share for all periods in which these escrow shares were outstanding based on the portion of the period they were in escrow. These shares were released from escrow on April 4, 2011. For the nine months ended September 30, 2010, the effect of assuming conversion of Quanta’s 3.75% convertible subordinated notes due 2026 (3.75% Notes) would have been antidilutive and therefore the shares issuable upon conversion were excluded from the calculation of diluted earnings per share. The 3.75% Notes were not outstanding after May 14, 2010 and therefore had no impact on diluted shares during the three and nine months ended September 30, 2011 or the three months ended September 30, 2010. </div> </div>

The entire amount of the facility is available for the issuance of letters of credit, and up to $25.0 million of the facility is available for swing line loans. Up to $100.0 million of the facility is available for revolving loans and letters of credit in certain alternative currencies in addition to the U.S. dollar.

The remaining $509.7 million was available for revolving loans or issuing new letters of credit. Amounts borrowed under the credit agreement in U.S. dollars bear interest, at Quanta’s option, at a rate equal to either (a) the Eurocurrency Rate (as defined in the credit agreement) plus 1.25% to 2.50%, as determined based on Quanta’s Consolidated Leverage Ratio (as described below), plus, if applicable, any Mandatory Cost (as defined in the credit agreement) required to compensate lenders for the cost of compliance with certain European regulatory requirements, or (b) the Base Rate (as described below) plus 0.25% to 1.50%, as determined based on Quanta’s Consolidated Leverage Ratio. Amounts borrowed under the credit agreement in any currency other than U.S. dollars bear interest at a rate equal to the Eurocurrency Rate plus 1.25% to 2.50%, as determined based on Quanta’s Consolidated Leverage Ratio, plus, if applicable, any Mandatory Cost. Standby letters of credit issued under the credit agreement are subject to a letter of credit fee of 1.25% to 2.50%, based on Quanta’s Consolidated Leverage Ratio, and Performance Letters of Credit (as defined in the credit agreement) issued under the credit agreement in support of certain contractual obligations are subject to a letter of credit fee of 0.75% to 1.50%, based on Quanta’s Consolidated Leverage Ratio. Quanta is also subject to a commitment fee of 0.20% to 0.45%, based on Quanta’s Consolidated Leverage Ratio, on any unused availability under the credit agreement. The Consolidated Leverage Ratio is the ratio of Quanta’s total funded debt to Consolidated EBITDA (as defined in the credit agreement). For purposes of calculating both the Consolidated Leverage Ratio and the maximum senior debt to Consolidated EBITDA ratio discussed below, total funded debt and total senior debt are reduced by all cash and Cash Equivalents (as defined in the credit agreement) held by Quanta in excess of $25.0 million.

Quanta’s wholly owned U.S. subsidiaries also guarantee the repayment of all amounts due under the credit agreement. Subject to certain conditions, at any time Quanta maintains a corporate credit rating that is BBB- (stable) or higher by Standard & Poor’s Rating Services and a corporate family rating that is Baa3 (stable) or higher by Moody’s Investors Services, all collateral will be automatically released from these liens. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> The credit agreement contains certain covenants, including a maximum Consolidated Leverage Ratio and a minimum interest coverage ratio, in each case as specified in the credit agreement.

In addition, the Restricted Stock Unit Plan (the RSU Plan) adopted by Quanta in 2010 provides for the award of RSUs to certain employees and consultants of Quanta’s Canadian operations. RSUs are intended to provide cash performance incentives that are substantially equivalent to the risks and rewards of equity ownership in Quanta by providing the participants with rights to receive a cash bonus that is determined by reference to Quanta’s common stock price. The number of RSUs awarded to grantees is determined based on the dollar amount of the grant and the closing price on the date of grant of a share of Quanta common stock. The RSUs vest over a designated period, typically three years, and are subject to forfeiture under certain conditions, primarily termination of service.

The California Department of Forestry and Fire Protection issued a report concluding that the Witch Creek fire was started when the conductors of a three phase 69kV transmission line, known as TL 637, owned by San Diego Gas & Electric (SDG&E), touched each other, dropping sparks on dry grass. The Witch Creek fire, together with another wildfire referred to as the Guejito fire that merged with the Witch Creek fire, burned a reported 198,000 acres, over 1,500 homes and structures and is alleged to have caused two deaths and numerous personal injuries. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Numerous additional lawsuits were filed directly against SDG&E and its parent company, Sempra, claiming SDG&E’s power lines caused the fire. The court ordered that the claims be organized into the four lawsuits mentioned above and grouped the matters by type of plaintiff, namely, insurance subrogation claimants, individual/business claimants, governmental claimants, and a class action matter, for which class certification has since been denied. PAR is not named as a defendant in any of these lawsuits against SDG&E or its parent. SDG&E has reportedly settled many of the claims. On June 18, 2010, SDG&E joined PAR to the four lawsuits as a third party defendant seeking contractual and equitable indemnification for losses related to the Witch Creek fire, although a claim for specific damages has not been made. SDG&E’s claims for indemnity relate to work done by PAR involving the replacement of one pole on TL 637 about four months prior to the Witch Creek fire. Quanta does not believe that the work done by PAR was the cause of the contact between the conductors. However, PAR has notified its various insurers of the claims. One insurer is participating in the defense of the matter, while others have reserved their rights to contest coverage, not stated their position <font style="white-space: nowrap">and/or</font> denied coverage. One insurer filed a lawsuit in the U.S. District Court for the Southern District of Texas, Houston Division on April 15, 2011 seeking a declaratory judgment that coverage does not exist. On June 6, 2011 and June 16, 2011, two other insurers intervened in the lawsuit making similar claims. On August 5, 2011, PAR filed a declaratory judgment action in California state court against certain insurers seeking a determination that coverage exists under the policies. PAR is vigorously defending the third party claims by SDG&E and continues to work to ensure coverage of any potential liabilities. An amount equal to the deductibles under certain of Quanta’s applicable insurance policies has been expensed in connection with these matters. We previously recorded a liability and corresponding insurance recovery receivable of $35 million associated with a policy that is not subject to any of the actions seeking to deny coverage, with the liability reserve being reduced as expenses are incurred in connection with these matters and the receivable being reduced as these expenses are reimbursed by the insurance carrier. Additional deductibles may apply depending upon the availability of coverage under other insurance policies. Given PAR’s defenses to the indemnity claims, as well as the potential for insurance coverage, Quanta cannot estimate the amount of any possible loss or the range of possible losses that may exceed Quanta’s applicable insurance coverage. However, due to the nature of these claims, an adverse result in these proceedings leading to a significant uninsured loss could have a material adverse effect on Quanta’s consolidated financial condition, results of operations and cash flows. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> <i>California Fire Claim — Amador County.</i>  In October 2004, a wildfire in Amador County, California, burned 16,800 acres. The United States Forest Service alleged that the fire originated as a result of the activities of a Quanta subsidiary crew performing vegetation management under a contract with Pacific Gas & Electric Co. (PG&E). In November 2007, the United States Department of Agriculture (USDA) sent a written demand to the Quanta subsidiary for payment of fire suppression costs of approximately $8.5 million. The USDA recently communicated verbally that it also intends to seek past and future restoration and other damages of approximately $51.3 million. No litigation has been filed.

Substantially all of Quanta’s cash investments are managed by what it believes to be high credit quality financial institutions. In accordance with Quanta’s investment policies, these institutions are authorized to invest this cash in a diversified portfolio of what Quanta believes to be high quality investments, which consist primarily of interest-bearing demand deposits, money market mutual funds and investment grade commercial paper with original maturities of three months or less. Although Quanta does not currently believe the principal amount of these investments is subject to any material risk of loss, the weakness in the economy has significantly impacted the interest income Quanta receives from these investments and is likely to continue to do so in the future. In addition, Quanta grants credit under normal payment terms, generally without collateral, to its customers, which include electric power, natural gas and pipeline companies, telecommunications service providers, governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States and Canada. Consequently, Quanta is subject to potential credit risk related to changes in business and economic factors throughout the United States and Canada, which may be heightened as a result of depressed economic and financial market conditions that have existed in recent years. However, Quanta generally has certain statutory lien rights with respect to services provided. 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. In such circumstances, extended time frames may be required to liquidate these assets, causing the amounts realized to differ from the value of the assumed receivable. Historically, some of Quanta’s customers have experienced significant financial difficulties, and others may experience financial difficulties in the future. These difficulties expose Quanta to increased risk related to collectability of billed and unbilled receivables and costs and estimated earnings in excess of billings on uncompleted contracts for services Quanta has performed. No customers represented 10% or more of billed and unbilled accounts receivable as of September 30, 2011, and no customers represented 10% or more of revenues for the three and nine months ended September 30, 2011. At December 31, 2010, one customer accounted for approximately 12% of billed and unbilled accounts receivables. Revenues from this customer are included in the Natural Gas and Pipeline Infrastructure Services segment. Additionally, one customer accounted for approximately 18% and one customer accounted for approximately 15% of consolidated revenues during the three months ended September 30, 2010, and one of these customers accounted for approximately 11% of consolidated revenues during the nine months ended September 30, 2010. Revenues from these customers are included in the Natural Gas and Pipeline Infrastructure Services segment. No other customers represented 10% or more of revenues during the three and nine months ended September 30, 2010. </div> <div style="margin-top: 12pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 2%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b><i><font style="font-family: 'Times New Roman', Times">Self-Insurance</font></i></b> </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta is insured for employer’s liability, general liability, auto liability and workers’ compensation claims.

The accruals are based upon known facts and historical trends, and management believes such accruals are adequate. As of September 30, 2011 and December 31, 2010, the gross amount accrued for insurance claims totaled $206.2 million and $216.8 million, with $159.0 million and $164.3 million considered to be long-term and included in other non-current liabilities. Related insurance recoveries/receivables as of September 30, 2011 and December 31, 2010 were $62.4 million and $66.3 million, of which $8.9 million and $9.4 million are included in prepaid expenses and other current assets and $53.5 million and $56.9 million are included in other assets, net. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta renews its insurance policies on an annual basis, and therefore deductibles and levels of insurance coverage may change in future periods.

In addition, from time to time some customers require Quanta to post letters of credit to ensure payment to its subcontractors and vendors and to guarantee performance under its contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit if the holder demonstrates that Quanta has failed to perform specified actions. If this were to occur, Quanta would be required to reimburse the issuer of the letter of credit.

None of Quanta’s operating units have any current plans to withdraw from these plans. In addition, the Pension Protection Act of 2006 added new funding rules generally applicable to plan years beginning after 2007 for multi-employer plans that are classified as “endangered,” “seriously endangered,” or “critical” status. For a plan in critical status, additional required contributions and benefit reductions may apply. A number of plans to which Quanta operating units contribute or may contribute in the future are in “critical” status. Certain of these plans may require additional contributions, generally in the form of a surcharge on future benefit contributions required for future work performed by union employees covered by the plans. The amount of additional funds, if any, that Quanta may be obligated to contribute to these plans in the future cannot be estimated, as such amounts will likely be based on future work that requires the specific use of the union employees covered by these plans, and the amount of that future work and the number of affected employees that may be needed cannot be estimated. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div>  <div style="margin-top: 12pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 2%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b><i><font style="font-family: 'Times New Roman', Times">Indemnities</font></i></b> </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta has indemnified various parties against specified liabilities that those parties might incur in the future in connection with Quanta’s previous acquisitions of certain companies.

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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div>  </div>   <div style="margin-left: 0%">  <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div> <div align="center" style="margin-left: 0%; margin-right: 0%; font-size: 10pt; font-family: Arial, Helvetica; color: #000000; background: transparent"> <b> <font style="font-family: 'Times New Roman', Times"> </font> </b> </div>  <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> Quanta’s intangible assets include customer relationships, backlog, trade names, non-compete agreements, patented rights and developed technology, all subject to amortization, along with other intangible assets not subject to amortization. The value of customer relationships is estimated as of the date a business is acquired using the <font style="white-space: nowrap">value-in-use</font> 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 as of the date a business is acquired 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 as of the date a business is acquired 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. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> 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. </div> </div> </div>

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 <font style="white-space: nowrap">ASU 2011-04</font> on January 1, 2012.

However, entities can choose to early adopt this ASU.

If an entity believes that, as a result of its qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. An entity can choose to perform the qualitative assessment on none, some or all of its reporting units. An entity can also bypass the qualitative assessment for any reporting unit in any period and proceed directly to step one of the impairment test, and then resume performing the qualitative assessment in any subsequent period.

This guidance requires employers to make various disclosures for each individually significant multiemployer plan that provides pension benefits to its employees. Generally, an employer must disclose the employer’s contributions to the plan during the period and provide a description of the nature and effect of any significant changes that affect comparability of total employer contributions from period to period. Additionally, the employer should provide a description of the nature of the plan benefits, a qualitative description of the extent to which the employer could be responsible for the obligations of the plan, including benefits earned by employees during employment with another employer and other quantitative information, to the extent available, as of the most recent date available, to help users understand the financial information for each significant plan. An employer should also provide disclosures for total contributions made to all plans that are not individually significant and total contributions made to all plans. If certain quantitative information cannot be obtained without undue cost and effort, that quantitative information may be omitted, although the employer should describe what information has been omitted and why. The required disclosures must be provided retrospectively for all prior periods.
