development and transportation of natural gas, oil and other pipeline products. Services performed by the Oil and Gas Infrastructure Services segment generally include the design, installation, repair and maintenance of pipeline transmission and
distribution systems, gathering systems, production systems, storage systems and compressor and pump stations, as well as related trenching, directional boring and mechanized welding services. In addition, this segment&#146;s services include
pipeline protection, integrity testing, rehabilitation and replacement, and fabrication of pipeline support systems and related structures and facilities. Quanta also serves the offshore and inland water energy markets, primarily providing services
to oil and gas exploration platforms, including mechanical installation (or &#147;hook-ups&#148;), electrical and instrumentation, pre-commissioning and commissioning, coatings, fabrication and marine asset repair. To a lesser extent, this segment
designs, installs and maintains fueling systems, as well as water and sewer infrastructure. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:2%; font-size:10pt; font-family:Times New Roman"><B><I>Acquisitions </I></B></P>

Quanta&#146;s Electric Power Infrastructure Services segment. These companies included an electrical infrastructure services company located in Australia, a utility contracting company located in Canada, a full service medium- and high-voltage
powerline contracting company located in the United States and a telecommunications company located in Canada. Quanta also acquired a pipeline service contractor located in the United States, the results of which are generally included in
Quanta&#146;s Oil and Gas Infrastructure Services segment. As these transactions were effective during 2016, the results have been included in Quanta&#146;s consolidated financial statements beginning on the respective dates of acquisition. These
acquisitions should enable Quanta to further enhance its service offerings in the United States, Australia and Canada. </P>

Cash consisting of interest-bearing demand deposits is carried at cost, which approximates fair value. Quanta considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents,
which are carried at fair value. At March&nbsp;31, 2017 and December&nbsp;31, 2016, cash equivalents were $8.1 million and $8.8 million, and consisted primarily of money market investments and money market mutual funds and are discussed further in
<I>Fair Value Measurements</I> below. As of March&nbsp;31, 2017 and December&nbsp;31, 2016, cash and cash equivalents held in domestic bank accounts were $17.5 million and $19.5 million, and cash and cash equivalents held in foreign bank accounts
were $89.0 million and $92.7 million. As of March&nbsp;31, 2017 and December&nbsp;31, 2016, cash and cash equivalents held by Quanta&#146;s investments in joint ventures, which are either consolidated or proportionately consolidated, were $8.8
million and $11.5 million, of which $7.7 million and $10.0 million related to domestic joint ventures. Cash and cash equivalents held by the joint ventures are available to support the operations of the related joint ventures, but Quanta does not
have access to that cash and cash equivalents for its other operations. Under the terms of the partnership agreements, Quanta generally has no right to the joint ventures&#146; cash and cash equivalents other than participating in distributions and

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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 regarding, among other factors, the customer&#146;s access to capital,
the customer&#146;s willingness or ability to pay, general economic and market conditions, the ongoing relationship with the customer and uncertainties related to the resolution of disputed matters. Quanta considers accounts receivable delinquent
after 30&nbsp;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&nbsp;days. In addition to balances that have been
outstanding for 90&nbsp;days or more, Quanta also includes accounts receivable balances that relate to customers in bankruptcy or with other known difficulties in its analysis of the allowance for doubtful accounts. Material changes in Quanta&#146;s
customers&#146; business or cash flows, which may be impacted by negative economic and market conditions, could affect Quanta&#146;s ability to collect amounts due from them. As of March&nbsp;31, 2017 and December&nbsp;31, 2016, Quanta had
allowances for doubtful accounts on current receivables of $5.0 million and $2.8 million. Long-term accounts receivable are included within other assets. </P>

provisions in certain contracts are generally due upon completion of the contracts and acceptance by the customer. Based on Quanta&#146;s experience with similar contracts in recent years, the majority of the retainage balances at each balance sheet
date are expected to be collected within the next twelve months. Current retainage balances as of March&nbsp;31, 2017 and December&nbsp;31, 2016 were $253.0 million and $231.0 million and were included in accounts receivable. Retainage balances with
settlement dates beyond the next twelve months were included in other assets, net, and as of March&nbsp;31, 2017 and December&nbsp;31, 2016 were $9.4 million and $5.2 million. </P>

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 March&nbsp;31, 2017 and December&nbsp;31, 2016, the balances of unbilled receivables included in accounts receivable were $296.7 million and $206.8 million. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta has recorded goodwill in connection with its historical acquisitions of companies. Upon acquisition, these companies
were either combined into one of Quanta&#146;s existing operating units or managed on a stand-alone basis as an individual operating unit. Goodwill recorded in connection with these acquisitions is subject to an annual assessment for impairment,
which Quanta performs at the operating unit level for each operating unit that carries a balance of goodwill. Each of Quanta&#146;s operating units is organized into one of two internal divisions: the Electric Power Infrastructure Services Division
and the Oil and Gas Infrastructure Services Division. As most of the companies acquired by Quanta provide multiple types of services for multiple types of customers, these divisional designations are based on the predominant type of work performed
by each operating unit at the point in time the divisional designation is made. Goodwill is required to be measured for impairment at the reporting unit level, which represents the operating segment level or one level below the operating segment
level for which discrete financial information is available. Quanta has determined that its individual operating units represent its reporting units for the purpose of assessing goodwill impairments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step fair
value-based impairment test described below. If Quanta 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. Quanta can choose to perform the qualitative assessment on none, some or all of its reporting units. Quanta 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 the qualitative assessment in any subsequent period. Qualitative indicators including deterioration in macroeconomic conditions, declining financial performance, or a sustained
decrease in share price, among other things, may trigger the need for annual or interim impairment testing of goodwill associated with one or all of the reporting units. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta&#146;s goodwill impairment assessment is performed at year-end, or more frequently if events or circumstances arise

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&#146;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&#146;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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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&#146;s opinion, this method currently results in the most accurate calculation of a reporting unit&#146;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, among others, revenue growth rates, operating margins, discount rates, weighted
average costs of capital and future market conditions. 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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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 one-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&#146;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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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&#146;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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">For recently acquired reporting units, a step one impairment test may indicate an implied fair value that is substantially
similar to the reporting unit&#146;s carrying value. Such similarities in value are generally an indication that management&#146;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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">During the fourth quarter of 2016, a two-step fair-value

reporting units, other than recently acquired reporting units and the reporting units that recorded goodwill impairment charges in 2015, was substantially in excess of its carrying value. </P>

reasonably likely to occur in future periods, including future market conditions and the economic environment in which Quanta&#146;s reporting units were operating. Additionally, management
considered the sensitivity of its fair value estimates to changes in certain valuation assumptions. After taking into account a 10% decrease in the fair value of each of Quanta&#146;s reporting units, two reporting units within Quanta&#146;s Oil and
Gas Infrastructure Division had fair values below their respective carrying values. Quanta recorded asset impairment charges for these reporting units in 2015. The fair values determined in 2016 for these reporting units were consistent with the
fair values determined in 2015, accordingly the fair values approximate the current carrying values. Circumstances such as market declines, unfavorable economic conditions, the loss of a major customer or other factors could increase the risk of
impairment of goodwill in future periods. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">If an operating unit experiences prolonged periods of declining revenues,
operating margins or both, it may be at risk of failing step one of the goodwill impairment test. Certain operating units have experienced declines over the short-term due to challenging macroeconomic conditions in certain geographic areas and low
oil and natural gas prices, which have negatively impacted customer spending and resulted in project cancellations and delays. Additionally, customer capital spending has been constrained as a result of an increasingly complex regulatory and
permitting environment. Certain operating units within Quanta&#146;s Oil and Gas Infrastructure Services Division that primarily operate within the midstream and smaller-scale transmission market have continued to be negatively impacted by these
factors. Goodwill and intangible assets associated with the operating units within Quanta&#146;s Oil and Gas Infrastructure Services Division that have been significantly impacted by the factors mentioned above were $69.8 million and $11.7 million
at March&nbsp;31, 2017. Quanta monitors these conditions and others to determine if it is necessary to perform step one of the fair-value based impairment test for one or more operating units prior to the annual impairment assessment. No interim
impairment charges were recorded during the three months ended March&nbsp;31, 2017. Although Quanta is not aware of circumstances that would lead to a goodwill impairment at a reporting unit currently, circumstances such as a continued market
decline, the loss of a major customer or other factors could impact the valuation of goodwill in the future. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta&#146;s intangible assets include customer relationships, backlog, trade names, non-compete agreements, patented rights
and developed technology, all subject to amortization. The value of customer relationships is estimated as of the date a business is acquired based on 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 and estimated customer attrition rates, the importance
or lack thereof of existing customer relationships to Quanta&#146;s business plan, income taxes and required rates of return. Quanta values backlog for acquired businesses as of the acquisition date based upon the contractual nature of the backlog

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. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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 business entities, including general or limited partnerships, contractual joint ventures, or other forms of equity or profit participation. These investments may also
include Quanta&#146;s participation in different financing 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 also enters into strategic partnerships with customers and infrastructure investors to provide fully integrated infrastructure services on certain projects, including planning and feasibility analysis, engineering, design, procurement,
construction financing and investment and project operation and maintenance. These projects include public-private partnerships, private infrastructure projects and concessions, along with build, own, operate and transfer and build to suit
arrangements. As part of this strategy, Quanta formed a partnership with select infrastructure investors that provides $750 million of capital available to invest in certain of these infrastructure projects, including $60 million from Quanta. Wholly
owned subsidiaries of Quanta serve as the general partner of this partnership and as a separately operating registered investment adviser to manage the invested capital. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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 have both (i)&nbsp;the power to direct the activities of a VIE that most significantly affect the VIE&#146;s economic performance and (ii)&nbsp;the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in
either case 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&#146;s equity interest in the VIE is accounted for as a non-controlling interest. In cases
where Quanta determines that it has an undivided interest in the assets, liabilities, revenues and profits of an unincorporated VIE (e.g., a general partnership interest), such amounts are consolidated on a basis proportional to Quanta&#146;s
ownership interest in the unincorporated entity. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Investments 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&#146;s share of net income or losses from unconsolidated equity investments is included in equity in earnings
(losses) of unconsolidated affiliates in the consolidated statements of operations when applicable. 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 related to investments would be recognized in other expense. Equity method investments are carried at original cost and are included in other assets, net in the consolidated balance sheet and are adjusted for
Quanta&#146;s proportionate share of the investees&#146; income, losses and distributions. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:2%; font-size:10pt; font-family:Times New Roman"><B><I>Revenue Recognition </I></B></P>

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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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, costs incurred to date compared to total estimated contract costs 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 material associated with Quanta&#146;s work is owner-furnished and is therefore not
included in contract revenues and costs. The cost estimation process is based on professional knowledge and experience of Quanta&#146;s engineers, project managers and financial professionals. Changes in job performance, job conditions and final
contract settlements are factors that influence management&#146;s assessment of total contract value and the total estimated costs to complete those contracts and therefore, Quanta&#146;s profit recognition. </P>

factors including unforeseen circumstances not included in Quanta&#146;s cost estimates or covered by its contracts for which it cannot obtain adequate compensation, including concealed or unknown environmental conditions; changes in the cost of
equipment, commodities, materials or labor; unanticipated costs or claims due to customer-caused delays, customer failure to provide required materials or equipment, errors in engineering, specifications or designs, project modifications, or
contract termination and Quanta&#146;s inability to obtain reimbursement for such costs or recover on such claims; weather conditions; and quality issues requiring rework or replacement. These factors, along with other risks inherent in performing
fixed price contracts may cause actual revenues and gross profits for a project to differ from previous estimates and could result in reduced profitability or losses on projects. 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. These factors are routinely evaluated on a project by project basis throughout the project term, and the impact of corresponding revisions in management&#146;s
estimates of contract value, contract cost and contract profit are recorded as necessary 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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Overall, Quanta&#146;s operating results for the three months

forfeiture rate; however, these estimates are subject to change and may impact the value that will ultimately be recognized as compensation expense. The resulting compensation expense from time-based RSU and performance unit 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 RSU awards is recognized using the graded vesting method over the requisite service period. Payments

fair value due to the short-term nature of these instruments. The carrying value of variable rate debt also approximates fair value. 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&#146;s cash equivalents were categorized as Level 1 assets at March&nbsp;31, 2017 and December&nbsp;31, 2016, as all values were based on unadjusted quoted prices for identical assets in an active market that Quanta
has the ability to access. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In connection with Quanta&#146;s acquisitions, identifiable intangible assets acquired
typically include goodwill, backlog, customer relationships, trade names, covenants not-to-compete, patented rights and developed technology. Quanta utilizes the fair value premise as the primary basis for its valuation procedures, which is a
market-based approach to determine 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, including 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. In accordance with its annual impairment test during the quarter ended December&nbsp;31, 2016, the carrying amounts of such assets, including goodwill, were compared
to their fair values. The level of inputs used for these fair value measurements is the lowest level (Level 3). Quanta uses the assistance of third party specialists to develop valuation assumptions. Quanta believes that these valuation methods
appropriately represent the methods that would be used by other market participants in determining fair value. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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

These types of fair market value assessments are similar to other nonrecurring 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

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In July 2015, the FASB issued an update that requires inventory to be measured at the lower of either cost or net realizable
value. When evidence exists that the net realizable value of inventory is lower than its cost, the difference will be recognized as a loss in earnings in the period in which it occurs. Quanta adopted this guidance effective January&nbsp;1, 2017, and
the adoption of the update did not have a significant impact on Quanta&#146;s consolidated financial statements or related disclosures. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In March 2016, the FASB issued an update that amends the accounting for share-based payments in several key areas, including
the treatment and cash flow presentation of tax effects related to the settlement of share-based payments and the accounting for forfeitures of share-based awards. The new guidance requires companies with share-based payments to record all tax
effects related thereto at settlement (or expiration) through income tax expense on the statement of operations rather than through additional paid-in capital (APIC) within equity. This update also requires excess tax benefits to be classified as an
operating activity on the statement of cash flows rather than reclassified as a financing activity and requires cash paid by an employer when withholding shares for taxes to be presented as a financing activity. The update also allows companies to
either account for forfeitures of share-based payments as they occur or to estimate forfeitures. This guidance is required to be applied prospectively except for the requirement to classify cash paid when withholding shares for the employee portion
of taxes as a financing activity, which requires retrospective application. Quanta adopted this guidance effective January&nbsp;1, 2017 and will continue to estimate forfeitures of share-based payments. Quanta anticipates increased volatility of
income tax expense after adoption of this guidance, and during the three months ended March&nbsp;31, 2017 recorded an income tax benefit of $4.9 million related to the settlement of share-based awards. APIC was not adjusted for amounts recorded
prior to 2017, and therefore Quanta&#146;s retained earnings were not affected by the adoption of this guidance as of January&nbsp;1, 2017. Additionally, $6.1 million was reclassified from an operating activity to a financing activity on the
statement of cash flows for the three months ended March&nbsp;31, 2016 associated with cash paid by Quanta to satisfy tax withholding obligations for share-settled awards. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In October 2016, the FASB issued an update that amends the consolidation guidance related to how a reporting entity that is
the single decision maker of a VIE should treat indirect interests in the VIE held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of a VIE. A reporting entity
has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. Quanta adopted this guidance on January&nbsp;1, 2017, and the adoption of the update did not have a significant impact
on its consolidated financial statements or related disclosures. </P>

recognition guidance. The update requires that the recognition of revenue related to the transfer of goods or services to customers reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This
update also requires new qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenues and cash flows arising from customer contracts, including significant judgments and changes in judgments, information
about contract balances and performance obligations, and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB affirmed its proposal to defer the effective date until fiscal years beginning on or after
December&nbsp;15, 2017. The guidance can be applied on a full retrospective or modified retrospective basis whereby the entity records a cumulative effect of initially applying this update at the date of initial application. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta is currently evaluating the potential impact of this update on its consolidated financial statements. Quanta currently
anticipates adopting the update using the modified retrospective transition method, which may result in a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. In addition, Quanta continues to
monitor activity related to the new standard as well as working with various non-authoritative groups regarding industry clarifications and interpretations, which may impact Quanta&#146;s considerations and conclusions. While Quanta is still
evaluating the requirements of this update, it currently does not expect the update to materially affect its results of operations, financial position or cash flows. This preliminary conclusion is based on Quanta&#146;s belief that it will generally
continue to recognize revenues from long-term service contracts over time as services are performed and the underlying obligation to the customer is fulfilled. Quanta has identified and is in the process of implementing changes to its processes and
internal controls to meet the reporting and disclosure requirements of this update and will adopt this update effective January&nbsp;1, 2018. </P>

disclosure of financial instruments to provide users of financial statements with more decision-useful information. The new standard is effective for interim and annual periods beginning after December&nbsp;15, 2017. Early adoption is permitted for
financial statements of fiscal years or interim periods that have not been previously issued. Quanta is evaluating the impact of the new standard on its consolidated financial statements and will adopt the new standard by January&nbsp;1, 2018. </P>

statements of fiscal years or interim periods that have not been previously issued. While Quanta continues to evaluate the effect of the standard on its consolidated financial statements, it is anticipated that the adoption of the standard will

amortized cost and to record allowances for available-for-sale (AFS) debt securities rather than reduce the carrying amounts. The update will also require disclosure of information regarding how a company developed its allowance, including changes

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In October 2016, the FASB issued an update that will require a reporting entity to recognize the tax expense from the sale of
an asset in the seller&#146;s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer&#146;s jurisdiction would also be
recognized at the time of the transfer. The new guidance will not apply to intra-entity transfers of inventory. The income tax consequences from the sale of inventory from one member of a consolidated entity to another will continue to be deferred
until the inventory is sold to a third party. The new standard is effective for interim and annual reporting periods beginning after December&nbsp;15, 2017, although early adoption is permitted. The modified retrospective method will be required for

or disposed of is concentrated in a single identifiable asset or group of similar identifiable assets, the asset or group is not a business. The update will require that to be considered a business, a set of assets and activities must include, at a
minimum, an input and a substantive process that together significantly contribute to the ability to create output. Additionally, the update will remove the evaluation of whether a market participant could replace missing elements in order to
consider the set of assets and activities a business, will provide more stringent criteria for sets without outputs and will narrow the definition of output. The new standard is effective for interim and annual reporting periods beginning after

Quanta&#146;s Electric Power Infrastructure Services segment. These companies included an electrical infrastructure services company located in Australia, a utility contracting company located in Canada, a full service medium- and high-voltage
powerline contracting company located in the United States and a telecommunications company located in Canada. Quanta also acquired a pipeline service contractor located in the United States, the results of which are generally included in
Quanta&#146;s Oil and Gas Infrastructure Services segment. The aggregate consideration for these acquisitions consisted of $75.9&nbsp;million paid or payable in cash, subject to certain adjustments, 70,840 shares of Quanta common stock valued at
$1.5&nbsp;million as of the settlement date of the applicable acquisition, and contingent consideration payments of up to $39.5 million, which will be paid if certain financial targets are achieved. Based on the estimated fair value of this
contingent consideration, Quanta recorded an $18.7 million liability. As these transactions were effective during 2016, the results have been included in Quanta&#146;s consolidated financial statements beginning on the respective dates of
acquisition. These acquisitions should enable Quanta to further enhance its service offerings in the United States, Australia and Canada. </P>

the recognition of the goodwill. In connection with the 2016 acquisitions, goodwill of $24.2 million was recorded for the acquired businesses that were included within Quanta&#146;s Electric Power Infrastructure Services Division and
$20.3&nbsp;million was recorded for acquired businesses that were included within Quanta&#146;s Oil and Gas Infrastructure Services Division on the dates of acquisition. Goodwill of $2.0&nbsp;million related to the 2016 acquisitions is expected to

have been prepared by adjusting the historical results of Quanta to include the historical results of the 2016 acquisitions as if they occurred January&nbsp;1, 2015. These pro forma combined historical results were also adjusted for the following: a
reduction of interest expense as a result of the repayment of outstanding indebtedness of the acquired businesses, a reduction of interest income as a result of the cash consideration paid net of cash received, an increase in amortization expense
due to the incremental intangible assets recorded related to the 2016 acquisitions, an increase or decrease 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&#146;s accounting policies, an increase in the number of outstanding shares of Quanta common stock and certain reclassifications to conform the acquired companies&#146; presentation to
Quanta&#146;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 resulted or may result from the acquisitions. As

to purchase, from time to time through February&nbsp;28, 2017, up to $1.25 billion of its outstanding common stock (the 2015 Repurchase Program). Repurchases under the 2015 Repurchase Program were made in open market and privately negotiated
transactions, including pursuant to an accelerated share repurchase arrangement and an issuer repurchase plan. During 2015, Quanta repurchased 19.2&nbsp;million shares of its common stock at a cost of $449.9 million in the open market under the 2015

arrangement (the ASR) to repurchase $750.0 million of its common stock under the 2015 Repurchase Program. Under the terms of the ASR, Quanta paid $750.0 million to JPMorgan Chase Bank, National Association, London Branch (JPMorgan) and initially
received 25.7&nbsp;million shares of its common stock. The fair market value of these 25.7&nbsp;million shares at the time of delivery was $600.0 million, and the repurchased shares and the related cost to acquire them were accounted for as an
adjustment to the balance of treasury stock during the third quarter of 2015, reducing the weighted-average number of basic and diluted common shares used to calculate Quanta&#146;s earnings per share. The $150.0 million remaining under the ASR was
recorded as an adjustment to APIC during the third quarter of 2015 and was reclassified from APIC to treasury stock upon final settlement of the ASR on April&nbsp;12, 2016. At final settlement and based on the final volume-weighted average share
price during the term of the ASR, minus a discount and subject to other adjustments pursuant to the terms and conditions of the ASR, Quanta received 9.4&nbsp;million additional shares of its common stock from JPMorgan. The 2015 Repurchase Program
ended on February&nbsp;28, 2017, and Quanta repurchased a total of 54.3&nbsp;million shares of its common stock at a cost of $1.20 billion under the 2015 Repurchase Program. No common stock was repurchased in the three months ended March&nbsp;31,

class action complaint in the Superior Court of California, County of Los Angeles, alleging various wage and hour violations against Telecom Network Specialists (TNS), a former subsidiary of Quanta.&nbsp;Quanta retained liability associated with
this matter pursuant to the terms of Quanta&#146;s sale of TNS in December 2012. Benton seeks to represent a class of workers that includes all persons who worked on certain TNS projects, including individuals that TNS retained through numerous
staffing agencies.&nbsp;The plaintiff class in this matter is seeking damages for unpaid wages, penalties associated with the failure to provide meal and rest periods and overtime wages, interest and attorneys&#146; fees. In September 2015, the
trial court certified the class as to workers from the various staffing companies at issue. In January 2017, the trial court granted a summary judgment motion filed by the plaintiff class and found that TNS was a joint employer of the class members
and that it failed to provide adequate meal and rest breaks and failed to pay overtime wages. Quanta believes this decision is not supported by controlling law and continues to contest liability in this matter.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Additionally, in November 2007, TNS filed cross complaints for indemnity and breach of contract against the staffing agencies,
which employed many of the individuals in question. In December 2012, the trial court heard cross-motions for summary judgment filed by TNS and the staffing agencies pertaining to TNS&#146;s demand for indemnity.&nbsp;The court denied TNS&#146;s
motion and granted the motions filed by the staffing agencies; however, the California Appellate Court reversed the trial court&#146;s decision in part and instructed the trial court to reconsider its ruling.&nbsp;In February 2017, the court denied
a new motion for summary judgment filed by the staffing companies and stated that the staffing companies were liable to TNS for any damages owed to the class members that the staffing companies employed. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The final amount of liability, if any, payable in connection with this matter remains the subject of pending litigation and
will ultimately depend on various factors, including the outcome of Quanta&#146;s appeal of the trial court&#146;s ruling and the solvency of the staffing agencies. Based on review and analysis of the trial court&#146;s rulings, Quanta does not
believe, at this time, that it is probable this matter will result in a material loss; however, a loss up to approximately $23 million remains reasonably possible upon final resolution of this matter. </P>

conditions could impact the interest income Quanta receives from these investments. In addition, Quanta grants credit under normal payment terms, generally without collateral, to its customers, which include electric power and oil and gas companies,
governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States, Canada and Australia. Consequently, Quanta is subject to potential credit risk related to
changes in business and economic factors throughout the United States, Canada and Australia, which may be heightened as a result of uncertain economic and financial market conditions that have existed in recent years. However, Quanta generally has
certain statutory lien rights with respect to services provided. Historically, some of Quanta&#146;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. </P>

Quanta is a party to grievance actions based on claims arising out of the collective bargaining agreements. The agreements require the operating units to pay specified wages, provide certain
benefits to their union employees and contribute certain amounts to multiemployer pension plans and employee benefit trusts. Quanta&#146;s multiemployer pension plan contribution rates generally are specified in the collective bargaining agreements
(usually on an annual basis), and contributions are made to the plans on a &#147;pay-as-you-go&#148; basis based on its union employee payrolls. The location and number of union employees that Quanta employs at any given time and the plans in which
they may participate vary depending on the projects Quanta has ongoing at any time and the need for union resources in connection with those projects. Therefore, Quanta is unable to accurately predict its union employee payroll and the amount of the
resulting multiemployer pension plan contribution obligation for future periods. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The Pension Protection Act of 2006 (PPA)
also added special funding and operational rules generally applicable to plan years beginning after 2007 for multiemployer plans that are classified as &#147;endangered,&#148; &#147;seriously endangered&#148; or &#147;critical&#148; status based on
multiple factors (including, for example, the plan&#146;s funded percentage, cash flow position and whether it is projected to experience a minimum funding deficiency). Plans in these classifications must adopt measures to improve their funded
status through a funding improvement or rehabilitation plan, as applicable, which may require additional contributions from employers (which may take the form of a surcharge on benefit contributions) and/or modifications to retiree benefits. Certain
plans to which Quanta contributes or may contribute in the future are in &#147;endangered,&#148; &#147;seriously endangered&#148; or &#147;critical&#148; status. The amount of additional funds, if any, that Quanta may be obligated to contribute to
these plans in the future cannot be estimated due to uncertainty of the future levels of work that require the specific use of union employees covered by these plans, as well as the future contribution levels and possible surcharges on contributions
applicable to these plans. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta may be subject to additional liabilities imposed by law as a result of its
participation in multiemployer defined benefit pension plans. For example, the Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980, imposes certain liabilities upon an employer who is
a contributor to a multiemployer pension plan if the employer withdraws from the plan or the plan is terminated or experiences a mass withdrawal. These liabilities include an allocable share of the unfunded vested benefits in the plan for all plan
participants, not merely the benefits payable to a contributing employer&#146;s own retirees. As a result, participating employers may bear a higher proportion of liability for unfunded vested benefits if other participating employers cease to
contribute or withdraw, with the reallocation of liability being more acute in cases when a withdrawn employer is insolvent or otherwise fails to pay its withdrawal liability. Other than as described below, Quanta is not aware of any material
amounts of withdrawal liability that have been incurred as a result of a withdrawal by any of Quanta&#146;s operating units from any multiemployer defined benefit pension plans. </P>

the Central States, Southeast and Southwest Areas Pension Plan (the Central States Plan). This withdrawal event was the result of an amendment to a collective bargaining agreement with the International Brotherhood of Teamsters (Teamsters) that
eliminated certain employers&#146; obligations to contribute to the Central States Plan, which was then in critical status and significantly underfunded as to its vested benefit obligations. The amendment was negotiated by the Pipe Line Contractors
Association (PLCA) on behalf of its members, which include certain Quanta subsidiaries. Because certain other Quanta subsidiaries continued participation in the Central States Plan into 2012, the Quanta subsidiaries&#146; withdrawals in 2011
effected only a partial withdrawal on behalf of Quanta for 2011. Quanta believed that the partial withdrawal was advantageous because it limited exposure to increased liability resulting from a future withdrawal event, at which point the Central

additional Quanta subsidiaries continued participation in the Central States Plan into 2012, Quanta believes that such subsidiaries withdrew from the Central States Plan in 2012, thereby effecting a complete withdrawal as of December&nbsp;30, 2012
for all Quanta subsidiaries.<I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In connection with the partial withdrawal in 2011, Quanta recorded a withdrawal
liability of approximately $32.6 million in the fourth quarter of 2011 based on estimates received from the Central States Plan. The Central States Plan subsequently asserted that the withdrawal of the PLCA members, and thus Quanta&#146;s partial
withdrawal, was not effective in 2011. The PLCA and Quanta believed at that time that a legally effective withdrawal had occurred during the fourth quarter of 2011, and this issue was litigated in the federal district court for the Northern District
of Illinois, Eastern Division. In September 2013, the district court ruled in favor of the Central States Plan, and that decision was appealed by the PLCA. In July 2014, the Central States Plan provided Quanta with a Notice and Demand claiming
partial withdrawal liability in the amount of $39.6 million and requiring Quanta to make payments on this assessment while the dispute is ongoing. In September 2015, the United States Court of Appeals for the Seventh Circuit ruled in favor of the
PLCA and reversed the district court&#146;s previous ruling which had been in favor of the Central States Plan. Based on the outcome of the appeal, in January 2016, the Central States Plan issued a revised Notice and Demand claiming a partial
withdrawal liability in the amount of $32.9 million. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Separately, in December 2013, the Central States Plan filed lawsuits
against two of Quanta&#146;s other subsidiaries in connection with their withdrawal in 2012. In the first lawsuit, the Central States Plan alleged that the subsidiary elected to participate in the Central States Plan pursuant to the collective
bargaining agreement under which it participated. Quanta argued that no such election was made and that any payments made to the Central States Plan were made in error. In July 2014, the parties reached an agreement to settle the lawsuit, and the
court dismissed the case with prejudice. In the second lawsuit, the Central States Plan alleged that contributions made by the Quanta subsidiary to a new industry fund created after Quanta withdrew from the Central States Plan should have been made
to the Central States Plan. This arguably would have extended the withdrawal date for this subsidiary to at least the end of 2013. Quanta disputed these allegations on the basis that it properly paid contributions to the new industry fund based on
the terms of the collective bargaining agreement under which it participated and asserted that it terminated its obligation to contribute to the Central States Plan by the end of 2012. The parties both moved for summary judgment, and in March 2015,
the court entered judgment in favor of Quanta. The Central States Plan filed a notice of appeal in April 2015, and in December 2015, the Central States Plan agreed to dismiss the appeal with prejudice. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The ultimate liability associated with the complete withdrawal of Quanta&#146;s subsidiaries from the Central States Plan will
depend on various factors, including interpretations of the terms of the collective bargaining agreements under which the subsidiaries participated and whether exemptions from withdrawal liability applicable to construction industry employers will
be available. In March 2014, the Central States Plan provided revised estimates indicating that the total withdrawal liability based on certain withdrawal scenarios from 2011 through 2014 could range between $40.1 million and $55.4 million, which
Quanta believes to be the range of reasonably possible loss for this matter. Additionally, based on those estimates and allowing for the exclusion of amounts believed by management to have been improperly included in such estimates, Quanta recorded
an adjustment to cost of services during the three months ended March&nbsp;31, 2014 to increase the recognized withdrawal liability to an amount within the range communicated to Quanta by the Central States Plan. Given the unknown nature of some of
the factors mentioned above, the final withdrawal liability cannot yet be determined with certainty. Accordingly, it is reasonably possible that the amount owed upon final resolution of these matters

of $6.9 million and requiring payments to be made on this assessment while the dispute is ongoing. In connection with the acquisition, Quanta recorded an initial liability of $4.8 million related to this withdrawal liability, and a portion of the
purchase price for the acquired company was deposited into an escrow account to fund any withdrawal obligation in excess of the initial liability recorded. In January 2016, the Central States Plan issued a revised Notice and Demand claiming a
withdrawal liability in the amount of $4.8 million. Although Quanta continues to dispute the total liability owed to the Central States Plan, it continues to make monthly payments according to the terms of this revised Notice and Demand while the

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta generally indemnifies its customers for the services it provides under its contracts, as well as other specified
liabilities, which may subject Quanta to indemnity claims and liabilities and related litigation. Additionally, in connection with certain acquisitions and dispositions, Quanta has indemnified various parties against specified liabilities that those
parties might incur in the future. The indemnities under acquisition or disposition agreements are usually contingent upon the other party incurring liabilities that reach specified thresholds. As of March&nbsp;31, 2017, except as otherwise set
forth above in <I>Legal Proceedings</I>, Quanta does not believe any material liabilities for claims exist against it in connection with any of these indemnity obligations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In the normal course of Quanta&#146;s acquisition transactions, Quanta obtains rights to indemnification from the sellers or
former owners of acquired companies for certain risks, liabilities and obligations arising from their prior operations, such as performance, operational, safety, workforce or tax issues, some of which Quanta may not have discovered during due
diligence. However, the indemnities may not cover all of Quanta&#146;s exposure for such pre-acquisition matters, and the indemnitors may be unwilling or unable to pay the amounts owed to Quanta. Accordingly, Quanta may incur expenses for which it
is not reimbursed. Quanta is currently in the process of identifying certain pre-acquisition obligations associated with non-U.S. payroll taxes that may be due from a business acquired by Quanta in 2013. As of March&nbsp;31, 2017, Quanta had

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta presents its operations under two reportable segments: (1)&nbsp;Electric Power Infrastructure Services and (2)&nbsp;Oil
and Gas Infrastructure Services. This structure is generally based on the broad end-user markets for Quanta&#146;s services. See Note&nbsp;1 for additional information regarding Quanta&#146;s reportable segments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Quanta&#146;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&#146;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&#146;s operating units are
organized into one of two internal divisions, namely, the Electric Power Infrastructure Services Division and the Oil and Gas Infrastructure Services Division. These internal divisions are closely aligned with the reportable segments described above
based on their operating units&#146; predominant type of work. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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&#146;s market strategies. These classifications of Quanta&#146;s operating unit revenues by type of work
for segment reporting purposes can at times require judgment on the part of management. Quanta&#146;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 service across industries. For example, Quanta performs joint trenching projects to install distribution lines for electric power and natural gas customers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In addition, Quanta&#146;s integrated operations and common administrative support at each of its operating units require that
certain allocations of shared and indirect costs, such as facility costs and indirect operating expenses, including depreciation and general and administrative costs, be 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 intangible assets are not allocated. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Summarized financial information for Quanta&#146;s reportable segments is presented in the following table (in thousands):

Form&nbsp;10-K for the year ended December&nbsp;31, 2016, which was filed with the Securities and Exchange Commission (SEC) on March&nbsp;1, 2017 and is available on the SEC&#146;s website at <U>www.sec.gov</U> and on our website, which is
<U>www.quantaservices.com</U>. The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We are a leading provider of specialty contracting services, offering infrastructure solutions primarily to the electric power,
oil and gas and communications industries in the United States, Canada and Australia and select other international markets. The services we provide include the design, installation, upgrade, repair and maintenance of infrastructure within each of
the industries we serve, such as electric power transmission and distribution networks, substation facilities, renewable energy facilities, and pipeline transmission and distribution systems and facilities. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We report our results under two reportable segments: (1)&nbsp;Electric Power Infrastructure Services and (2)&nbsp;Oil and Gas
Infrastructure Services. This structure is generally focused on broad end-user markets for our services. Our consolidated revenues for the three months ended March&nbsp;31, 2017 were $2.18 billion, of which 56.0% was attributable to the Electric
Power Infrastructure Services segment and 44.0% was attributable to the Oil and Gas Infrastructure Services segment. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Our
customers include many of the leading companies in the industries we serve. We have developed strong strategic alliances with numerous customers and strive to develop and maintain our status as a preferred vendor to our customers. We enter into
various types of contracts, including competitive unit price, hourly rate, cost-plus (or time and materials basis), and fixed price (or lump sum basis), the final terms and prices of which are frequently negotiated with the customer. Although the
terms of our contracts vary considerably, most are made on either a unit price or fixed price basis in which we agree to do the work for a price per unit of work performed (unit price) or for a fixed amount for the entire project (fixed price). We
complete a substantial majority of our fixed price projects, other than certain large transmission projects, within one year, while we frequently provide maintenance and repair work under open-ended unit price or cost-plus master service agreements
that are renewable periodically. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We recognize revenue on our unit price and cost-plus contracts as units are completed or
services are performed. For our fixed price contracts, we record revenues as work on the contract progresses on a percentage-of-completion basis. Under this method, revenue is recognized based on the percentage of total costs incurred to date in
proportion to total estimated costs to complete the contract. Fixed price contracts generally include retainage provisions under which a percentage of the contract price is withheld until the project is complete and has been accepted by our
customer. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">For internal management purposes, we are organized into two internal divisions, namely, the Electric Power
Infrastructure Services Division and the Oil and Gas Infrastructure Services Division. These internal divisions are closely aligned with the reportable segments described above based on the predominant type of work provided by the operating units
within each division. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">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 our market strategies. </P>

These classifications of our operating unit revenues by type of work for segment reporting purposes can at times require judgment on the part of management. Our operating units may perform joint
infrastructure service projects for customers in multiple industries, deliver multiple types of infrastructure services under a single customer contract or provide services across industries. For example, we perform joint trenching projects to
install distribution lines for electric power and natural gas customers. Our integrated operations and common administrative support at each of our 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, be 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 intangible assets are not allocated. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The
Electric Power Infrastructure Services segment provides comprehensive network solutions to customers in the electric power industry. Services performed by the Electric Power Infrastructure Services segment generally include the design, installation,
upgrade, repair and maintenance of electric power transmission and distribution infrastructure and substation facilities along with other engineering and technical services. This segment also provides emergency restoration services, including the
repair of infrastructure damaged by inclement weather, the energized installation, maintenance and upgrade of electric power infrastructure utilizing unique bare hand and hot stick methods and our proprietary robotic arm technologies, and the
installation of &#147;smart grid&#148; technologies on electric power networks. In addition, this segment designs, installs and maintains renewable energy generation facilities, consisting of solar, wind and certain types of natural gas generation
facilities, and related switchyards and transmission infrastructure. To a lesser extent, the segment also provides comprehensive communications infrastructure services to wireline, fiber and wireless carrier customers within the communications
industry, and services in connection with the construction of electric power generation facilities, the design, installation, maintenance and repair of commercial and industrial wiring, and the installation of traffic networks and cable and control
systems for light rail lines. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The Oil and Gas Infrastructure Services segment provides comprehensive network solutions to
customers involved in the development and transportation of natural gas, oil and other pipeline products. Services performed by the Oil and Gas Infrastructure Services segment generally include the design, installation, repair and maintenance of
pipeline transmission and distribution systems, gathering systems, production systems, storage systems and compressor and pump stations, as well as related trenching, directional boring and mechanized welding services. In addition, this
segment&#146;s services include pipeline protection, integrity testing, rehabilitation and replacement, and fabrication of pipeline support systems and related structures and facilities. We also serve the offshore and inland water energy markets,
primarily providing services to oil and gas exploration platforms, including mechanical installation (or &#147;hook-ups&#148;), electrical and instrumentation, pre-commissioning and commissioning, coatings, fabrication and marine asset repair. To a
lesser extent, this segment designs, installs and maintains fueling systems, as well as water and sewer infrastructure. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We also enter into strategic partnerships with customers and infrastructure investors to provide fully integrated
infrastructure services on certain projects, including planning and feasibility analysis, engineering, design, procurement, construction financing and investment and project operation and maintenance. These projects include public-private
partnerships, private infrastructure projects and concessions, along with build, own, operate and transfer and build to suit arrangements. As part of this strategy, we formed a partnership with select infrastructure investors that provides $750
million of capital available to invest in certain of these infrastructure projects, including $60 million from us. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Recent Investments, Acquisitions

infrastructure services company located in Australia, a utility contracting company located in Canada, a full service medium- and high-voltage powerline contracting company located in the United
States and a telecommunications company located in Canada. We also acquired a pipeline service contractor located in the United States, the results of which are generally included in our Oil and Gas Infrastructure Services segment. The aggregate
consideration for these acquisitions consisted of $75.9 million paid or payable in cash, subject to certain adjustments, 70,840 shares of Quanta common stock valued at $1.5 million as of the settlement date of the applicable acquisition, and
contingent consideration payments of up to $39.5 million, which will be paid if certain financial targets are achieved. Based on the estimated fair value of this contingent consideration, we have recorded an $18.7 million liability. As these
transactions were effective during 2016, the results have been included in our consolidated financial statements beginning on the respective dates of acquisition. These acquisitions should enable us to further enhance our service offerings in the
United States, Canada and Australia. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Backlog </B></P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Our backlog represents the amount of consolidated revenues that we expect to realize from future work under construction
contracts, long-term maintenance contracts and master service agreements (MSAs). These estimates include revenues from the remaining portion of firm orders not yet completed and on which work has not yet begun, as well as revenues from change
orders, renewal options, and funded and unfunded portions of government contracts to the extent that they are reasonably expected to occur. For purposes of calculating backlog, we include 100% of estimated revenues attributable to consolidated joint
ventures and variable interest entities (VIEs). The following table presents our total backlog by reportable segment as of March&nbsp;31, 2017 and December&nbsp;31, 2016, along with an estimate of the backlog amounts expected to be realized within

accelerations, cancellations or delays due to various factors, including but not limited to commercial issues, regulatory requirements and adverse weather. These factors can also cause revenue amounts to be realized in periods and at levels
different than originally projected. During the three month period ended March&nbsp;31, 2017, we reduced our 12-month backlog for the Oil and Gas Infrastructure Services segment by approximately $100 million as a result of a cancellation of a
natural gas pipeline project, for which we received a termination fee. Generally, our customers are not contractually committed to specific volumes of services under our MSAs, and most of our contracts may be terminated, typically upon 30 to 90
days&#146; notice, even if we are not in default under the contract. We determine the estimated amount of backlog for work under MSAs by using recurring historical trends inherent in current MSAs, factoring in seasonal demand and projected customer
needs based upon ongoing communications with the customer. In addition, many of our MSAs are subject to renewal options. As of March&nbsp;31, 2017 and December&nbsp;31, 2016, MSAs accounted for 43% and 42% of our estimated 12-month backlog and 53%
of total backlog. There can be no assurance as to our customers&#146; actual requirements or that our estimates are accurate. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Seasonality; Fluctuations of Results; Economic Conditions </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Our revenues and results of operations can be subject to seasonal and other variations. These variations are influenced by
weather, customer spending patterns, bidding seasons, receipt of required regulatory approvals, permits and rights of way, project timing and schedules, and holidays. Typically, our revenues are lowest in the first quarter of the year because cold,
snowy or wet conditions can cause delays on projects. In addition, many of our customers develop their capital budgets for the coming year during the first quarter and do not begin infrastructure projects in a meaningful way until their capital
budgets are finalized. Second quarter revenues are typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather can often impact second quarter productivity. Third quarter revenues are typically the
highest of the year, as a greater number of projects are underway, and weather is more accommodating. Generally, revenues during the fourth quarter of the year are lower than the third quarter but higher than the second quarter. Many projects are
completed in the fourth quarter, and revenues are often impacted positively by customers seeking to spend their capital budgets before the end of the year; however, the holiday season and inclement weather can sometimes cause delays, reducing
revenues and increasing costs. Any quarter may be positively or negatively affected by atypical weather patterns in any of the areas we serve, such as severe weather, excessive rainfall or unusual winter weather, making it difficult to predict these
variations and their effect on particular projects quarter to quarter. The timing of project awards and unanticipated changes in project schedules as a result of delays or accelerations can also create variations in the level of operating activity
from quarter to quarter. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">These seasonal impacts are typical for our U.S. operations, but as our foreign operations
continue to grow, we may see a lessening of this pattern impacting our quarterly revenues. For example, revenues in Canada are often higher in the first quarter as projects are accelerated so that work can be completed prior to the break up, or
seasonal thaw, as productivity is adversely affected by wet ground conditions during the warmer spring and summer months. Also, although revenues from Australia and other international operations have not been significant relative to our overall
revenues to date, their seasonal patterns may differ from those in North America and may impact our seasonality more in the future. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Additionally, our industry can be highly cyclical. Our volume of business may be adversely affected by declines or delays in
new projects due to cyclicality, which may vary by geographic region, including the United States, Canada and Australia. Project schedules, particularly in connection with larger, longer-term projects, can also create fluctuations in the services
provided, which may adversely affect us in a given period. For example, in connection with larger, more complicated projects, the timing of obtaining permits and other approvals may be delayed, and we may need to maintain a portion of our workforce
and equipment in an underutilized capacity to ensure we are strategically positioned to deliver on such projects when they move forward. Examples of other items that may cause our results or demand for our services to fluctuate materially from
quarter to quarter include: the financial condition of our customers and their access to capital; margins of projects performed during any particular period; regional, national and global economic and market conditions; our customers&#146; capital
spending, including on larger pipeline and electrical infrastructure projects; natural gas and oil prices; the timing of acquisitions, the timing and magnitude of acquisition and integration costs associated with acquisitions; dispositions; equity
in earnings (losses) of unconsolidated affiliates; impairments of goodwill, intangible assets, long-lived assets or investments; effective tax rates and interest rates. Accordingly, our operating results in any particular period may not be
indicative of the results that can be expected for any other period. Please read<I> Outlook</I> and<I> Understanding Margins</I> for additional discussion of trends and challenges that may affect our financial condition, results of operations and
cash flows. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Understanding Margins </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Our gross margin is gross profit expressed as a percentage of revenues, and our operating margin is operating income expressed
as a percentage of revenues. Cost of services, which is subtracted from revenues to obtain gross profit, consists primarily of salaries, wages and benefits to employees, depreciation, fuel and other equipment expenses, equipment rentals,
subcontracted services, insurance, facilities expenses, materials and parts </P>

and supplies. Selling, general and administrative expenses and amortization of intangible assets are then subtracted from gross profit to obtain operating income. Various factors, some that are
controllable and some that are not, can impact our margins on a quarterly or annual basis. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Seasonal and
geographical.</I> As discussed previously, seasonal patterns can have a significant impact on margins. Generally, business is slower in the winter months versus the warmer months of the year, resulting in lower productivity and consequently reducing
our ability to cover fixed costs. This can be offset somewhat by<I> </I>increased demand for electrical service and repair work resulting from severe weather. Additionally, project schedules, including when projects begin and when they are
completed, may impact margins. The mix of<I> </I>business conducted in the areas we serve will also affect margins, as some of the areas we serve offer the opportunity for higher margins than others due to the geographic characteristics associated
with the physical location where the work is being performed. Such characteristics include whether the project is performed in an urban versus a rural setting or in a mountainous area or in open terrain. Site conditions, including unforeseen
underground conditions, can also impact margins.<I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Weather.</I> Adverse or favorable weather conditions can
impact gross margins in a given period. For example, snowfall or rainfall in the areas in which we operate may negatively impact our revenues and margins due to reduced productivity, as projects may be delayed or temporarily placed on hold until
weather conditions improve. Conversely, in periods when weather remains dry and temperatures are accommodating, more work can be done, sometimes with less cost, which would have a favorable impact on margins. In some cases, severe weather, such as
hurricanes and ice storms, can provide us with higher margin emergency restoration service work, which generally has a positive impact on margins.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Revenue mix.</I> The mix of revenues derived from the industries we serve and the types of services we provide within an
industry will impact margins, as certain industries and services provide higher margin opportunities. Additionally, changes in our customers&#146; spending patterns in each of the industries we serve can cause an imbalance in supply and demand and,
therefore, affect margins and mix of revenues by industry served.<I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Service and maintenance versus
installation.</I>&nbsp;Installation work is often performed on a fixed price basis, while maintenance work is often performed under pre-established or negotiated prices or cost-plus pricing arrangements. Margins for installation work may vary from
project to project, and may be higher than maintenance work, as work obtained on a fixed price basis has higher risk than other types of pricing arrangements. We typically derive approximately 30% of our annual revenues from maintenance work, but a
higher portion of installation work in any given period may affect our gross margins for that period. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Subcontract
work.</I> Work that is subcontracted to other service providers generally yields lower margins. An increase in subcontract work in a given period may contribute to a decrease in margins. We typically subcontract approximately 20% to 25% of our work
to other service providers.<I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Materials versus labor.</I> Typically, our customers are responsible for supplying
their own materials on projects; however, for some of our contracts, we may agree to procure all or part of the required materials. Margins may be lower on projects where we furnish a significant amount of materials, as our mark-up on materials is
generally lower than on our labor costs. In a given period, an increase in the percentage of work with higher materials procurement requirements may decrease our overall margins.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Size, scope and complexity of projects. </I>We may experience a decrease or fluctuations in margins when larger, more
complex electric transmission and pipeline projects across the industries we serve experience significant delays. Larger projects with higher voltage capacities, larger diameter throughput capacities, increased construction or design complexities,
more difficult terrain requirements or longer distance requirements typically yield opportunities for higher margins as we assume a greater degree of performance risk and allow for a higher degree of utilization of our resources for longer
construction timeframes. Conversely, smaller or less complex electric transmission and pipeline projects typically provide lower margin opportunities<I> </I></P>

</I>as there are a greater number of competitors capable of performing in this market, and competitors at times may more aggressively pursue available volumes of work to absorb fixed costs. A
greater mix of smaller scale or less complex electric transmission and pipeline work also could negatively impact margins due to the inefficiency of transitioning between a greater number of smaller projects versus continuous production on fewer
larger projects.<I> </I>Our margins may be further impacted by delays in the timing of larger projects or temporary decreases in capital spending by our customers, as we may choose to maintain a portion of our workforce and equipment in an
underutilized capacity to ensure we are strategically positioned to deliver on larger, more complicated electric transmission or pipeline projects when they move forward.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Depreciation.</I> We include depreciation in cost of services. This is common practice in our industry, but it can make
comparability of our margins to those of other companies difficult. This must be taken into consideration when comparing us to other companies.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Insurance. </I>As discussed in <I>Liquidity and Capital Resources &#151;&nbsp;Self-Insurance</I>, we are insured for
employer&#146;s liability, workers&#146; compensation, auto liability and general liability claims. We also have employee health care benefit plans for most employees not subject to collective bargaining agreements. Margins could be impacted by
fluctuations in insurance accruals as additional claims arise and as circumstances and conditions of existing claims change.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Performance risk.</I> Margins may fluctuate because of the volume of work and the impacts of pricing and job productivity,
which can be affected both favorably and negatively by, among other things, weather, geography, customer decisions and crew productivity. For example, when comparing a service contract between a current quarter and the comparable prior year&#146;s
quarter, factors affecting the gross margins associated with the revenues generated by the contract may include pricing under the contract, the volume of work performed under the contract, the mix of the type of work specifically being performed and
the productivity of the crews performing the work. Productivity can be influenced by many factors, including where the work is performed (e.g., rural versus urban area or mountainous or rocky area versus open terrain), whether the work is on an open
or encumbered right of way, the impact of inclement weather, the effects of environmental restrictions or regulatory delays, or the performance of third parties on a project. These types of factors are not practicable to quantify through accounting
data, but each of these items may individually or in the aggregate have a direct impact on the gross margin of a specific project.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Foreign currency risk. </I>Our financial performance is reported on a U.S. dollar-denominated basis but is partially
subject to fluctuations in foreign currency exchange rates. Fluctuations in exchange rates relative to the U.S. dollar, primarily the Canadian and Australian dollars, could cause material fluctuations in comparisons of our results of operations
between periods.<I> </I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Selling, General and Administrative Expenses </B></P>

administrative salaries and benefits, marketing, office rent and utilities, communications, professional fees, bad debt expense, acquisition costs, gains and losses on the sale of property and equipment, letter of credit fees and maintenance,

</I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Revenues.</I>&nbsp;Revenues increased $464.4 million, or 27.1%, to $2.18 billion for the three months ended
March&nbsp;31, 2017. Contributing to the increase was a $431.9 million increase in revenues from oil and gas infrastructure services and a $32.5 million increase in revenues from electric power infrastructure services. The increase in revenues from
oil and gas infrastructure services primarily resulted from increased capital spending by our customers on larger pipeline transmission projects, as certain of these projects, after experiencing regulatory and permitting delays, moved into full
construction during the second half of 2016 and remained in full construction during the first quarter of 2017. The increase in revenues from electric power infrastructure services resulted primarily from increased customer spending associated with
larger transmission services, $18.7 million in additional emergency restoration services revenues and approximately $10 million in revenues from acquired companies. Foreign currency exchange rates also favorably impacted revenues by approximately
$20 million during the three months ended March&nbsp;31, 2017, primarily attributable to the strengthening of the Canadian dollar against the U.S. dollar. </P>

of revenues were primarily due to the increase in revenues described above, as well as greater contributions from larger pipeline project margins and the incremental emergency restoration services<I>

expenses.</I>&nbsp;Selling, general and administrative expenses increased $26.0&nbsp;million, or 16.4%, to $184.6&nbsp;million for the three months ended March&nbsp;31, 2017. This increase was primarily attributable to $17.2&nbsp;million in higher
compensation costs, largely associated with higher incentive compensation based on current levels of profitability, as well as annual compensation increases and increased personnel to support business growth; $5.8 million in higher attorneys&#146;
fees and related expenses due to ongoing and resolved litigation, $4.2 million of which was associated with a matter involving our prior disposition of certain communications operations that was resolved in the three months ended March&nbsp;31,
2017; and a $1.9&nbsp;million loss associated with the planned sale of a construction barge. Other increases primarily include additional costs related to the support of increased revenues and costs associated with ongoing technology and business
development initiatives. Partially offsetting these increases were $6.3 million in severance costs associated with the departure of our former president and chief executive officer and severance and restructuring costs primarily associated with
certain operations within the Oil and Gas Infrastructure Services segment recognized in the three months ended March&nbsp;31, 2016. Selling, general and administrative expenses as a percentage of revenues decreased to 8.5% for the three months ended
March&nbsp;31, 2017 from 9.3% for the three months ended March&nbsp;31, 2016. This decrease was due primarily to the increase in revenues. <I> </I></P>

the three months ended March&nbsp;31, 2017. This decrease was primarily due to reduced amortization expense from previously acquired intangible assets as certain of these assets became fully amortized, partially offset by increased amortization of
intangible assets associated with acquired companies. <I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Interest expense.</I>&nbsp;Interest expense increased
$0.4 million to $4.0 million for the three months ended March&nbsp;31, 2017 due to a higher weighted average interest rate during the first quarter of 2017, partially offset by decreased borrowing activity. <I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Provision for income taxes.</I>&nbsp;The provision for income taxes was $22.6 million for the three months ended
March&nbsp;31, 2017, with an effective tax rate of 31.8%. The provision for income taxes was $13.4 million for the three months ended March&nbsp;31, 2016, with an effective tax rate of 39.2%. The lower effective tax rate for the three months ended
March&nbsp;31, 2017 was primarily due to a discrete income tax benefit of $4.9 million associated with an accounting update adopted on January&nbsp;1, 2017 that amended the accounting for share-based payments.&nbsp;The new guidance requires
companies with share-based payments to record all tax effects related thereto at settlement (or expiration) through income tax expense on the statement of operations rather than through additional paid-in capital (APIC) within equity. <I> </I></P>

ended March&nbsp;31, 2017 compared to a gain of $60.6 million in the three months ended March&nbsp;31, 2016. The gain in the three months ended March&nbsp;31, 2017 was due to a strengthening of foreign currencies associated with our international
operations, primarily the Canadian and Australian dollars, against the U.S. dollar as of March&nbsp;31, 2017 when compared to exchange rates for those same currencies as of December&nbsp;31, 2016. Similarly, the gain in the three months ended
March&nbsp;31, 2016 was due to a strengthening of foreign currencies associated with our international operations, primarily the Canadian and Australian dollars, against the U.S. dollar as of March&nbsp;31, 2016 when compared to exchange rates for

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Revenues for this segment increased $32.5 million, or 2.7%, to $1.22 billion&nbsp;for the three months ended March&nbsp;31,
2017. This increase was primarily due to increased customer spending associated with larger electric transmission projects, $18.7&nbsp;million in additional emergency restoration services revenues and approximately $10&nbsp;million in revenues from
acquired companies. Foreign currency exchange rates also favorably impacted revenues by approximately $8 million during the three months ended March&nbsp;31, 2017, primarily attributable to the strengthening of the Canadian dollar against the U.S.
dollar. Partially offsetting these increases was a decrease in renewable power project related revenues, and to a lesser extent, a reduction in revenues associated with a power plant project in Alaska that was substantially completed in the fourth
quarter of 2016. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Operating income increased $12.3 million, or 14.1%, to $99.7 million for the three months ended
March&nbsp;31, 2017. Operating income as a percentage of segment revenues increased to 8.2% for the three months ended March&nbsp;31, 2017 from 7.4% for the three months ended March&nbsp;31, 2016. These increases primarily resulted from the prior
period being negatively impacted by $21.3&nbsp;million of project losses recognized during the three months ended March&nbsp;31, 2016 related to a power plant project in Alaska, as well as from the positive impact of incremental emergency
restoration services revenues in the three months ended March&nbsp;31, 2017, which typically yield higher margins. Partially offsetting these items were lower electric transmission margins primarily due to a larger Canadian transmission project that
has been recorded at lower margins to address performance risk associated with challenging project conditions, as well as variations due to typical seasonality and the timing of project start dates and completions. </P>

This increase was primarily the result of increased capital spending by our customers on larger pipeline transmission projects, as certain of these projects, after experiencing regulatory and permitting delays, moved into full construction during
the second half of 2016 and remained in full construction during the first quarter of 2017. Revenues also increased as a result of foreign currency exchange rates during the three months ended March&nbsp;31, 2017, which favorably impacted our
international operations by approximately $12 million and were primarily attributable to the strengthening of the Canadian dollar against the U.S. dollar. </P>

ended March&nbsp;31, 2017. Operating income as a percentage of segment revenues increased to 4.0% for the three months ended March&nbsp;31, 2017 from 1.1% for the three months ended March&nbsp;31, 2016. These increases were primarily due to greater
contributions from larger pipeline projects, which typically yield higher margins. In addition, overall higher revenues in the segment allowed for better coverage of fixed and overhead costs. Also contributing to the increase in operating income was
the favorable impact of a termination fee associated with a project cancellation. These increases were partially offset by the negative impact of adverse weather conditions on certain projects during the quarter, as well as lower margins on two
distribution MSAs due to unexpected delays in the release of work after crews were mobilized. Operating income and operating income as a percentage of revenues in the three months ended March&nbsp;31, 2017 were also impacted by a $1.9&nbsp;million
loss associated with the planned sale of a construction barge, while the first quarter of 2016 was impacted by approximately $2 million in severance and restructuring costs. </P>

resulted in an increase of the estimated total costs necessary to complete the project. During the three months ended March&nbsp;31, 2017, we recognized losses on the project of $16.5&nbsp;million. We are in the process of developing potential
claims; however, no revenues or cost recovery has been reflected in our estimate of total project losses at March&nbsp;31, 2017. At March&nbsp;31, 2017, this project was approximately 85% complete. As this project continues, it is possible that
additional delays or other unforeseen circumstances could occur and result in the recognition of additional losses on this project; however, such amounts cannot currently be estimated. </P>

Corporate and non-allocated costs for the quarter ended March&nbsp;31, 2017 increased $7.5&nbsp;million to $63.4 million as compared to the quarter ended March&nbsp;31, 2016. This increase was primarily due to the $4.2&nbsp;million of
attorneys&#146; fees and related expenses associated with a matter involving our prior disposition of certain communications operations that was resolved in the three months ended March&nbsp;31, 2017. The remaining increase was related to increased
corporate functions, including $3.5&nbsp;million of higher compensation costs, largely associated with higher incentive compensation based on current levels of profitability, and $1.8&nbsp;million of increased costs associated with information
technology initiatives. These increases were partially offset by $4.0 million in costs associated with the departure of our former president and chief executive officer recognized in the three months ended March&nbsp;31, 2016. </P>

opportunities to make investments in strategic partnerships with customers and infrastructure investors where we anticipate performing services such as project management, engineering, procurement or construction services. These investment
opportunities exist in the markets and industries we serve and may require the use of cash in the form of debt or equity investments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Management continues to monitor the financial markets and general national and global economic conditions for factors that may
affect our liquidity and capital resources. We consider our cash and cash equivalents investment policies to be conservative in that we maintain a diverse portfolio of what we believe to be high-quality cash and cash equivalent investments with
short-term maturities. Accordingly, we do not anticipate that any weakness in the capital markets will have a material impact on the principal amounts of our cash and cash equivalents or our ability to rely upon our credit facility for funds. To
date, we have experienced no loss of or lack of access to our cash or cash equivalents or funds under our credit facility; however, we can provide no assurances that access to our invested cash and cash equivalents or availability under our credit

additional U.S. income and foreign withholding taxes if we were to repatriate cash that is indefinitely reinvested outside of the United States. Because of the number and variability of assumptions required, it is not practicable to determine the
amount of any additional U.S. tax liability that may result if we decide to no longer indefinitely reinvest foreign earnings outside the United States. If our intentions or U.S. tax laws change in the future, there may be a significant negative
impact on the provision for income taxes and cash flows as a result of recording an incremental tax liability in the period such change occurs. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Cash flow from operations is primarily influenced by demand for our services and operating margins but can also be influenced
by working capital needs associated with the various types of services that we provide. In particular, working capital needs may increase when we commence large volumes of work under circumstances where project costs, primarily associated with
labor, equipment and subcontractors, are required to be paid before the receivables resulting from the work performed are billed and collected. Accordingly, changes within working capital in accounts receivable, costs and estimated earnings in
excess of billings on uncompleted contracts, and billings in excess of costs and estimated earnings on uncompleted contracts are normally related and are typically affected on a collective basis by changes in revenue due to both changes in the
timing and volume of work performed and variability in the timing of customer billings and payments. Additionally, working capital needs are generally higher during the summer and fall months due to increased demand for our services when favorable
weather conditions exist in many of the regions in which we operate. Conversely, working capital assets are typically converted to cash during the winter months. These seasonal trends can be offset by changes in the timing of projects which can be
impacted by project delays or accelerations and other economic factors that may affect customer spending. </P>

during the three months ended March&nbsp;31, 2017 as compared to $205.8 million provided during the three months ended March&nbsp;31, 2016. This decrease in cash flows from operating activities of continuing operations was partly due to additional
working capital requirements associated with an increase in the number and size of oil and gas infrastructure projects that moved into full construction during the second half of 2016 and remained in full construction during the first quarter of
2017. In addition, the timing of revenues was more heavily weighted toward the last month of the first quarter of 2017, partly due to emergency restoration work performed in March. Also contributing to the decrease in cash flows from operating
activities of continuing operations were invoicing challenges and billing delays on two related electric transmission projects located in remote regions of northeastern Canada which resulted from extensive quality assurance documentation and
administrative requirements. We continue to work collaboratively with this customer to improve the invoicing and billing processes on these projects. These decreases were partially offset by the positive impact of improved operating results. </P>

increase was primarily due to the impact of invoicing challenges and billing delays on the two related large electric transmission projects in remote regions of northeastern Canada discussed above and more favorable billing terms for certain
projects ongoing in 2016 as compared to projects ongoing in 2017. DSO is calculated by using the sum of current accounts receivable, net of allowance (which includes retainage and unbilled balances), plus costs and estimated earnings in excess of

agreement contains certain covenants, including a maximum Consolidated Leverage Ratio and a minimum Consolidated Interest Coverage Ratio (as defined in the credit agreement). The credit agreement also limits certain acquisitions, mergers and
consolidations, indebtedness, asset sales and prepayments of indebtedness and, subject to certain exceptions, prohibits liens on our assets. The credit agreement allows cash payments for dividends and stock repurchases subject to compliance with the
following requirements (after giving effect to the dividend or stock repurchase): (i)&nbsp;no default or event of default under the credit agreement; (ii)&nbsp;continued compliance with the financial covenants in the credit agreement; and
(iii)&nbsp;at least $100.0 million of availability under the credit agreement and/or cash and cash equivalents on hand. As of March&nbsp;31, 2017, we were in compliance with all of the covenants in the credit agreement. </P>

surety guarantees related to performance bonds, certain multiemployer pension plan liabilities and obligations relating to our investments and joint venture arrangements. Certain joint venture structures involve risks not directly reflected in our

venture arrangements qualify as a general partnership, for which we are jointly and severally liable for all of the obligations of the joint venture. In our joint venture arrangements, typically
each joint venture party indemnifies the other party for any liabilities incurred in excess of the liabilities such other party is obligated to bear under the respective joint venture agreement. Other than as discussed in this report, we have not
engaged in any material off-balance sheet financing arrangements through special purpose entities, and we have no material guarantees of the work or obligations of third parties. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We enter into non-cancelable operating leases for many of our facility, vehicle and equipment needs. These leases allow us to
conserve cash by paying a monthly lease rental fee for use of facilities, vehicles and equipment rather than purchasing them. We may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the
lessor for the remaining lease payments under the term of the lease. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We have guaranteed the residual value of the
underlying assets under certain of our equipment operating leases at the date of termination of such leases. We have agreed to pay any difference between this residual value and the fair market value of each underlying asset as of the lease
termination date. As of March&nbsp;31, 2017, the maximum guaranteed residual value was $573.3 million. We believe that no significant payments will be made as a result of the difference between the fair market value of the leased equipment and the
guaranteed residual value. However, there can be no assurance that future significant payments will not be required. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:2%; font-size:10pt; font-family:Times New Roman"><B><I>Letters of

behalf, such as to beneficiaries under our self-funded insurance programs. In addition, from time to time, certain customers require us to post letters of credit to ensure payment to our subcontractors and vendors under those contracts and to
guarantee performance under our contracts. Such letters of credit are generally issued by a bank or similar financial institution, typically pursuant to our credit agreement. Each letter of credit commits the issuer to pay specified amounts to the
holder of the letter of credit if the holder claims that we have failed to perform specified actions. If this were to occur, we would be required to reimburse the issuer of the letter of credit. Depending on the circumstances of such a
reimbursement, we may also be required to record a charge to earnings for the reimbursement. We do not believe that it is likely that any material claims will be made under a letter of credit in the foreseeable future. </P>

insurance program and various contractual commitments. These are irrevocable stand-by letters of credit with maturities generally expiring at various times throughout 2017 and 2018. Upon maturity, it is expected that the majority of the letters of
credit related to the casualty insurance program will be renewed for subsequent one-year periods. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:2%; font-size:10pt; font-family:Times New Roman"><B><I>Performance Bonds and Parent

contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the surety for any expenses or outlays it incurs. Under our underwriting, continuing indemnity
and security agreement with our sureties and with the consent of the lenders that are party to our credit agreement, we have granted security interests in certain of our assets to collateralize our obligations to the sureties. Subject to certain
conditions and consistent with terms of our credit agreement, these security interests will be automatically released if we maintain a credit rating that meets two of the following three conditions: (i)&nbsp;a corporate credit rating that is BBB- or

borrowing availability under our credit facility. To date, we have not been required to make any reimbursements to our sureties for bond-related costs. We believe that it is unlikely that we will have to fund significant claims under our surety
arrangements in the foreseeable future. As of March&nbsp;31, 2017, the total amount of outstanding performance bonds was estimated to be approximately $3.4 billion. Our estimated maximum exposure as it relates to the value of performance bonds
outstanding is lowered on each bonded project as the cost to complete is reduced, and each of our commitments under the performance bonds generally extinguishes concurrently with the expiration of our related contractual obligation. The estimated
cost to complete these bonded projects was approximately $910 million as of March&nbsp;31, 2017. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Additionally, from time

pension plans in which our union employees participate. Some of our operating units are parties to various collective bargaining agreements that require us to provide to the employees subject to these agreements specified wages and benefits, as well
as to make contributions to multiemployer pension plans. Our multiemployer pension plan contribution rates generally are specified in the collective bargaining agreements (usually on an annual basis), and contributions are made to the plans on a
&#147;pay-as-you-go&#148; basis based on our union employee payrolls. The location and number of union employees that we employ at any given time and the plans in which they may participate vary depending on the projects we have ongoing at any time
and the need for union resources in connection with those projects. Therefore, we are unable to accurately predict our union employee payroll and the amount of the resulting multiemployer pension plan contribution obligations for future periods.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We may also be required to make additional contributions to our multiemployer pension plans if they become underfunded,
and these additional contributions will be determined based on our union employee payrolls. The Pension Protection Act of 2006 added special funding and operational rules generally applicable to plan years beginning after 2007 for multiemployer
plans that are classified as &#147;endangered,&#148; &#147;seriously endangered&#148; or &#147;critical&#148; status. Plans in these classifications must adopt measures to improve their funded status through a funding improvement or rehabilitation
plan, as applicable, which may require additional contributions from employers (which may take the form of a surcharge on benefit contributions) and/or modifications to retiree benefits. A number of multiemployer plans to which our operating units
contribute or may contribute in the future are in &#147;endangered,&#148; &#147;seriously endangered&#148; or &#147;critical&#148; status. The amount of additional funds, if any, that we may be obligated to contribute to these plans in the future

Multiemployer Pension Plan Amendments Act of 1980, imposes certain liabilities upon employers who are contributors to a multiemployer plan if the employer withdraws from the plan or the plan is
terminated or experiences a mass withdrawal. These liabilities include an allocable share of the unfunded vested benefits in the plan for all plan participants, not merely the benefits payable to a contributing employer&#146;s own retirees. Other
than as noted below, we are not aware of any material amounts of withdrawal liability that have been or are expected to be incurred as a result of a withdrawal by any of our operating units from any multiemployer defined benefit pension plans. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>2011 Central States Plan Withdrawal Liability. </I>In the fourth quarter of 2011, certain of our subsidiaries withdrew from
the Central States, Southeast and Southwest Areas Pension Plan (the Central States Plan). This withdrawal event was the result of an amendment to a collective bargaining agreement with the International Brotherhood of Teamsters (Teamsters) that
eliminated certain employers&#146; obligations to contribute to the Central States Plan, which was then in critical status and significantly underfunded as to its vested benefit obligations. The amendment was negotiated by the Pipe Line Contractors
Association (PLCA) on behalf of its members, which include certain of our subsidiaries. Because certain of our other subsidiaries continued participation in the Central States Plan into 2012, the subsidiaries&#146; withdrawals in 2011 effected only
a partial withdrawal on our behalf in 2011. We believed that the partial withdrawal was advantageous because it limited exposure to increased liability resulting from a future withdrawal event, at which point the Central States Plan could have been
further underfunded. We and other PLCA members now contribute to a different multiemployer pension plan on behalf of the affected Teamsters employees. While certain of our subsidiaries continued participation in the Central States Plan into 2012, we
believe that such subsidiaries withdrew from the Central States Plan in 2012, thereby effecting a complete withdrawal as of December&nbsp;30, 2012 for all Quanta subsidiaries.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In connection with the partial withdrawal in 2011, we recorded a withdrawal liability of approximately $32.6 million in the
fourth quarter of 2011 based on estimates received from the Central States Plan. The Central States Plan subsequently asserted that the withdrawal of the PLCA members, and thus our partial withdrawal, was not effective in 2011. The PLCA and Quanta
believed at that time that a legally effective withdrawal had occurred during the fourth quarter of 2011, and this issue was litigated in the federal district court for the Northern District of Illinois, Eastern Division. In September 2013, the
district court ruled in favor of the Central States Plan, and that decision was appealed by the PLCA. In July 2014, the Central States Plan provided us with a Notice and Demand claiming partial withdrawal liability in the amount of $39.6 million and
requiring Quanta to make payments on this assessment while the dispute is ongoing. In September 2015, the United States Court of Appeals for the Seventh Circuit ruled in favor of the PLCA and reversed the district court&#146;s previous ruling, which
had been in favor of the Central States Plan. Based on the outcome of the appeal, in January 2016, the Central States Plan issued a revised Notice and Demand claiming partial withdrawal liability in the amount of $32.9 million. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Separately, in December 2013, the Central States Plan filed lawsuits against two of our subsidiaries in connection with their
withdrawal in 2012. In the first lawsuit, the Central States Plan alleged that the subsidiary elected to participate in the Central States Plan pursuant to the collective bargaining agreement under which it participated. We argued that no such
election was made and that any payments made to the Central States Plan were made in error. In July 2014, the parties reached an agreement to settle the lawsuit, and the court dismissed the case with prejudice. In the second lawsuit, the Central
States Plan alleged that contributions made by our subsidiary to a new industry fund created after we withdrew from the Central States Plan should have been made to the Central States Plan. This arguably would have extended our withdrawal date for
this subsidiary to at least the end of 2013. We disputed these allegations on the basis that we properly paid contributions to the new industry fund based on the terms of the collective bargaining agreement under which we participated and asserted
that we terminated our obligation to contribute to the Central States Plan by the end of 2012. The parties both moved for summary judgment, and in March 2015, the court entered judgment in our favor. The Central States Plan filed a notice of appeal
in April 2015, and in December 2015, the Central States Plan agreed to dismiss the appeal with prejudice. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The ultimate liability associated with the complete withdrawal of our
subsidiaries from the Central States Plan will depend on various factors, including interpretations of the terms of the collective bargaining agreements under which the subsidiaries participated and whether exemptions from withdrawal liability
applicable to construction industry employers will be available. In March 2014, the Central States Plan provided revised estimates indicating that the total withdrawal liability based on certain withdrawal scenarios from 2011 through 2014 could
range between $40.1 million and $55.4 million, which we believe to be the range of reasonably possible loss for this matter. Additionally, based on those estimates and allowing for the exclusion of amounts believed by management to have been
improperly included in such estimates, we recorded an adjustment to cost of services during the three months ended March&nbsp;31, 2014 to increase the recognized withdrawal liability to an amount within the range communicated to us by the Central
States Plan. Given the unknown nature of some of the factors mentioned above, the final withdrawal liability cannot yet be determined with certainty. Accordingly, it is reasonably possible that the amount owed upon final resolution of these matters
could be materially higher than the expense we recognized through March&nbsp;31, 2017. Although we dispute the total liability owed to the Central States Plan, we continue to make monthly payments according to the terms of the January 2016 Notice
and Demand while the parties determine the final withdrawal liability. As of March&nbsp;31, 2017, we had made payments totaling $19.1 million toward the withdrawal liability assessment. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>2013 Central States Plan Withdrawal Liability.</I> On October&nbsp;9, 2013, we acquired a company that experienced a
complete withdrawal from the Central States Plan prior to the date of acquisition. Prior to the acquisition, the Central States Plan issued a Notice and Demand to the acquired company claiming a withdrawal liability in the total amount of $6.9
million and requiring payments to be made on this assessment while the dispute is ongoing. In connection with the acquisition, we recorded an initial liability of $4.8 million related to this withdrawal liability, and a portion of the purchase price
for the acquired company was deposited into an escrow account to fund any withdrawal obligation in excess of the initial liability recorded. In January 2016, the Central States Plan issued a revised Notice and Demand claiming a withdrawal liability
in the amount of $4.8&nbsp;million. Although we continue to dispute the total liability owed to the Central States Plan, we continue to make monthly payments according to the terms of this revised Notice and Demand while the parties determine the
final withdrawal liability. As of March&nbsp;31, 2017, payments totaling $3.7 million had been made toward the withdrawal liability assessment.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The final amount of withdrawal liability payable in connection with this matter remains the subject of a pending arbitration

accruals are adequate. As of March&nbsp;31, 2017 and December&nbsp;31, 2016, the gross amount accrued for insurance claims totaled $220.0 million and $218.2 million with $162.1 million and $162.0&nbsp;million considered to be long-term and included

our cash and cash equivalents are managed by what we believe to be high credit quality financial institutions. In accordance with our investment policies, these institutions are authorized to invest cash and cash equivalents in a diversified
portfolio of what we believe to be high quality investments, which primarily include interest-bearing demand deposits, money market investments, money market mutual funds and investment grade commercial paper with original maturities of three months
or less. Although we do not currently believe the principal amount of these cash and cash equivalents is subject to any material risk of loss, changes in economic conditions could impact the interest income we receive from these investments. In
addition, we grant credit under normal payment terms, generally without collateral, to our customers, which include electric power and oil and gas companies, governmental entities, general contractors, and builders, owners and managers of commercial

the treatment and cash flow presentation of tax effects related to the settlement of share-based payments and the accounting for forfeitures of share-based awards. The new guidance requires companies with share-based payments to record all tax
effects related thereto at settlement (or expiration) through income tax expense on the statement of operations rather than through APIC within equity. This update also requires excess tax benefits to be classified as an operating activity on the
statement of cash flows rather than reclassified as a financing activity and requires cash paid by an employer when withholding shares for the employee portion of taxes to be presented as a financing activity. The update also allows companies to
either account for forfeitures of share-based payments as they occur or to estimate forfeitures. This guidance is required to be applied prospectively except for the requirement to classify cash paid when withholding shares for taxes as a financing
activity, which requires retrospective application. We adopted this guidance effective January&nbsp;1, 2017 and will continue to estimate forfeitures of share-based payments. Quanta anticipates increased volatility of income tax expense upon

reliability and reduce congestion. Among other things, these activities include new construction, structure change-outs, line upgrades and maintenance projects on many transmission systems. In addition, state renewable portfolio standards, which set
required or voluntary standards for how much power is to be generated from renewable energy sources, can result in the need for additional transmission lines and substations to transport the power from these facilities, which are often in remote
locations, to demand centers. Other factors, such as the reliability standards issued by the North American Electric Reliability Corporation and other regulatory actions, are also driving transmission system upgrades and expansions. We believe these
factors create significant opportunities for our transmission infrastructure services. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Demand for electricity in North America is expected to grow over the long term.
Certain segments of the North American electric power grid are not adequate to efficiently serve the power needs of the future. The electric power grid is aging and, in some cases, lacks redundancy. The increasing demand for electricity, coupled
with these issues, has affected and will continue to affect reliability, requiring utilities to upgrade and expand their existing transmission and distribution systems. Current federal legislation also requires the power industry to meet federal
reliability standards for its transmission and distribution systems. We expect these system upgrades could result in increased spending and increased demand for our services over the long term. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">As demand for power grows, the need for new power generation facilities is expected to grow. The development of new
traditional power generation facilities, as well as renewable energy sources such as solar, wind and certain types of natural gas generation facilities, requires new or expanded transmission infrastructure to transport power to demand centers.
Renewable energy sources in particular often require significant transmission infrastructure due to their remote location. As a result, we anticipate that future development of new power generation will lead to increased demand over the long term
for our electric transmission design and construction services, as well as our substation engineering and installation services. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The significant improvement in access to natural gas resources from unconventional shale formations in the United States and
Canada, driven by technological advancements, has dramatically increased the near- and long-term supply of natural gas in North America. This increase in supply has also resulted in low natural gas prices for the past several years. As a result, it
is anticipated that the amount of electricity generated by natural gas powered plants will increase and, for the foreseeable future, the majority of fossil fuel generation facilities built in North America will be fueled by natural gas. Further, the
Environmental Protection Agency has implemented certain emissions regulations that have resulted in the development of natural gas generation facilities to replace coal generation plants that are being retired. To the extent these dynamics continue,
they are expected to result in the need for additional North American transmission and substation infrastructure to interconnect new natural gas fired generation facilities. It is also anticipated that modifications to and reengineering of existing
transmission and substation infrastructure will be required as existing coal and nuclear generation facilities are retired or shut down. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We consider renewable energy, including solar and wind generation facilities, to be an ongoing opportunity for our
engineering, project management and installation services. Concerns about greenhouse gas emissions, as well as the goal of reducing reliance on power generation from fossil fuels, have created demand for more renewable energy sources. Renewable
portfolio standards, which mandate that renewable energy constitute a specified percentage of a utility&#146;s power generation by a specified date, exist in many states. We believe that our comprehensive services, industry knowledge and experience
in the design, installation and maintenance of renewable energy facilities will enable us to support renewable energy efforts. However, we believe there is some uncertainty whether some of these projects will advance to award and construction. The
economic feasibility of renewable energy projects, and therefore the attractiveness of investment in such projects, may depend on the availability of tax incentive programs or the ability of the project developer to take advantage of such
incentives. There is no assurance that the government will extend existing tax incentives or create new incentive or funding programs. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The Federal Energy Regulatory Commission (FERC) issued FERC Order No.&nbsp;1000 to promote more efficient and cost-effective
development of new transmission facilities. The order establishes transmission planning and cost allocation requirements intended to facilitate multi-state electric transmission lines and to encourage competition by removing, under certain
conditions, federal rights of first refusal from FERC-approved tariffs and agreements. In the short-term, we believe implementation of and compliance with the order has created some confusion and uncertainty for utilities and regulators, which has
adversely impacted the timing of some potential transmission projects and spending, and that modifications may be necessary to spur certain intended transmission investment. If these challenges are resolved, we believe FERC Order No.&nbsp;1000 has
the potential to favorably impact electric transmission line development over time, particularly for large, high-voltage electric transmission projects. </P>

positively affect demand for the services provided by this segment in the long term, particularly in connection with electric power infrastructure and renewable energy spending. For example, legislative or regulatory action that alleviates some of
the siting and right-of-way challenges that impact transmission projects would potentially accelerate future transmission line construction. We also anticipate increased infrastructure spending by our customers as a result of regulation requiring
the power industry to meet federal reliability standards for its transmission and distribution systems and providing incentives to the industry to invest in and improve maintenance on its systems. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The regulatory and environmental permitting processes remain a hurdle for some proposed transmission and renewable energy

However, we expect many of these projects to move forward over a multi-year period. The timing and scope of projects can also be affected by other factors such as siting, right-of-way and unfavorable economic and market conditions. We anticipate
many of these issues to be overcome and spending on transmission projects to be active over the next few years, and we currently have a number of these projects underway and expect this segment&#146;s backlog to remain strong throughout 2017. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In the near-term, margins in our Electric Power Infrastructure Services segment have experienced pressure as construction of
several large, high-voltage transmission projects has been delayed due to the challenging regulatory approval and permitting environment. Due to these delays and the general expectation that these projects have not been cancelled, we believe there
have been excess transmission contractor resources in the small and medium size transmission marketplace in some areas, resulting in increased competition and pricing pressure for those services. These factors, in addition to challenging regional
economic conditions, have impacted our Canadian operations in particular. Over the past few quarters, we believe these competitive pressures and Canadian economic conditions have begun to stabilize. We will remain focused on maintaining our pricing
discipline and believe competitive pressures could recede further as large, high-voltage transmission projects move forward and the small and medium size transmission market continues to grow and/or contractors adjust further to the current
environment. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We benefited from increases in electric power distribution spending throughout the last several years,

utilities are implementing system upgrades or &#147;hardening&#148; programs in response to severe weather events that have occurred over the past few years, which is also increasing distribution investment in some regions of the United States. We
also anticipate that utilities will continue to integrate &#147;smart grid&#148; technologies into their distribution systems over time to improve grid management and create efficiencies. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The need to ensure available specialized labor resources for projects also drives strategic relationships with customers. In
addition, several industry and market trends are prompting customers to seek ongoing service arrangements. These trends include an aging utility workforce and labor availability issues, increasing pressure to reduce costs and improve reliability,
and increasing duration and complexity of customer capital programs. Due to these and other factors, we believe customer demand for labor resources will continue to increase, possibly outpacing the supply of industry resources. We recognize that our
ability to take advantage of this opportunity is also limited by our ability to employ, train and retain the necessary skilled personnel, and that an aging utility workforce and labor availability issues affect us as well. As a result, we are taking
proactive steps to develop our workforce, including through the establishment and expansion of our training facility for electric power, pipeline and communications training. </P>

densification and network improvements to existing wireless networks and for the deployment of new wireless networks continue in North America. For example, many providers are planning for the deployment of 5G networks over the coming years, which
we believe will require significant investment in new small cellular networks and fiber optic backhaul networks to handle the large expected increase in data traffic. There are similar consumer and commercial demands for interconnectivity and
services in Latin America; however, the region is significantly behind North America with respect to wireline and wireless network development. Most of Latin America relies on 3G wireless technology where wireless coverage is available and there is
little 4G wireless coverage. Further, fiber optic and other high-speed networks are not widely available in many areas of Latin America. Governments in some Latin American countries are also working to implement initiatives to interconnect less
developed areas to each other and to more developed areas for communication, economic and quality of life purposes. As a result of these near and longer-term industry trends, we believe there is meaningful demand for our communications engineering
and construction services. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Certain international regions present significant opportunities for growth over time across
many of our operations. We are evaluating ways in which we can strategically apply our expertise in various foreign countries where infrastructure enhancements are increasingly important. For example, we are actively pursuing opportunities in growth
markets where we can leverage our technology or proprietary work methods, such as our energized services, to establish a presence. In Canada, we are leveraging our electric power infrastructure services resources, relationships and reputation to
expand and grow our communication infrastructure services operations. In addition, over the last several years we have successfully developed our communication infrastructure services operations in several Latin American countries that could enable
us to expand our infrastructure services to that region. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:2%; font-size:10pt; font-family:Times New Roman"><B><I>Oil and Gas Infrastructure Services Segment </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We continue to see growth opportunities in our Oil and Gas Infrastructure Services segment, primarily in the installation and
maintenance of larger pipeline and related facilities, as well as pipeline integrity, natural gas distribution systems and specialty services such as horizontal directional drilling. In certain areas of North America, the existing pipeline system
infrastructure is insufficient to support future development of unconventional shale formations and the Canadian oil sands. We believe that the development of such resources, though facing challenges in the near term, may continue over the long term
and that building this infrastructure would take a number of years, which we expect should increase demand for our services over the long term. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Despite our positive long-term outlook, a challenging regulatory and permitting environment has caused delays of some larger
pipeline projects during the past several years. These dynamics resulted in below average larger pipeline construction opportunities for us and the industry and negatively impacted our Oil and Gas Infrastructure Services segment margins, in part as
a result of our inability to adequately cover certain fixed costs. Margins for larger pipeline projects are also subject to significant performance risk, which can arise from adverse weather conditions, challenging geography, customer decisions and
crew productivity. Our specific opportunities in the larger pipeline business are sometimes difficult to predict because of the seasonality of the bidding and construction cycles within the industry. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">A number of larger pipeline projects from the North American shale formations and Canadian oil sands to power plants,
refineries and other demand centers are in various stages of development. Most of the larger pipeline projects we are working on, have in backlog or see as future potential opportunities are driven by natural gas production and demand. We believe
the abundant natural gas supply, combined with attractive prices, will </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="justify">
increase demand for natural gas in the future. The U.S. Energy Information Administration has stated that the number of natural gas-fired power plants built will increase significantly over the
next two decades. Power generation from renewable energy sources also continues to increase and become a larger percentage of the overall power generation mix. We also believe natural gas will be the fuel of choice to provide backup power generation
during times when renewable energy sources are not available. These factors could create a need for additional pipeline infrastructure to connect natural gas supplies to demand centers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In addition, the abundance, low price and long-term supply of North American natural gas has resulted in efforts to develop
liquefied natural gas (LNG) export facilities in the United States, Canada and Australia, which could provide pipeline and related facilities development opportunities for us. Natural gas prices in various international markets are significantly
higher than North American natural gas prices, making the economics of exporting North American natural gas to international markets attractive. A number of LNG export facilities are in various stages of planning, permitting and development in the
United States and Canada. Although we cannot be certain how many of these projects will move forward, as they could be affected by changing pricing and economic conditions, we believe our comprehensive service offerings and broad geographic presence
enable us to competitively pursue pipeline and related facilities infrastructure opportunities that become available. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We
also see a number of larger oil pipeline project opportunities, particularly in Canada. Although many of these projects are still developing, a significant number of projects have been awarded to us and other pipeline contractors in recent years and
are moving towards construction.&nbsp;Given the costs and time required to bring a larger pipeline project from conception to construction, we believe many of our customers view such projects as important, strategic pieces of infrastructure, have a
long-term perspective regarding their needs, and are not primarily influenced by short term commodity price fluctuations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">In certain areas of North America, pipeline takeaway capacity is not sufficient to economically move oil from production areas
to demand centers for current and/or anticipated future oil production. As a result, certain proposed larger oil pipeline projects are being developed and have secured producers under contractual arrangements, making these projects economically
viable despite the decline in oil prices. Several of these projects are intended to move oil from the Canadian oil sands to the east and west coast of Canada in order to access demand markets in Europe, Asia and other areas. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">While there is risk that these projects will not move forward or could be delayed, we are encouraged by the proposed larger
pipeline development plans and the successful progression of certain larger pipeline projects, which we believe is indicative of an improved and favorable large pipeline market over the next several years in North America. We expect to execute on a
significant number of larger pipeline projects during 2017, though this activity could be more pronounced in the first half of 2017. However, if oil and natural gas prices decline further or remain at lower levels for a prolonged period, our outlook
may change and demand for our oil and natural gas infrastructure services could be materially impacted. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We also believe
there are growth opportunities for some of our other pipeline services, including pipeline integrity, rehabilitation and replacement services, over the long-term. The U.S. Department of Transportation has implemented regulatory legislation through
the Pipeline and Hazardous Materials Safety Administration (PHMSA) relating to pipeline integrity requirements. PHMSA continues to develop, propose and implement additional safety and pipeline integrity regulation for liquid and natural gas
pipelines. To the extent finalized and implemented, the proposed new regulations would strengthen requirements for safety, operation, inspection and maintenance of pipelines and provide pipeline operators with regulatory certainty. Further, these
measures would require that pipeline integrity testing requirements increase in stringency and frequency, which we expect to result in an increase in spending by our customers on pipeline integrity initiatives. We also operate an engineering,
research and development business that develops and owns pipeline inspection tools that could benefit from this dynamic. We believe our ability to offer a complete pipeline integrity turnkey solution to pipeline companies and gas utilities positions
us to take advantage of available opportunities. </P> <P STYLE="font-size:12pt; margin-top:0pt; margin-bottom:0pt">&nbsp;</P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We are also experiencing an increase in demand for our natural gas distribution
services as a result of improved economic conditions, lower natural gas prices and a significant need to upgrade and replace aging infrastructure. A number of states, particularly states in the northeast United States that have cities and areas with
older natural gas distribution infrastructure, have approved and are implementing regulations and multi-year programs to replace cast iron, wrought iron and bare steel natural gas infrastructure, which is prone to failure with age, with modern and
safer pipe material. We expect this to take an extended period of time, which should provide attractive growth opportunities for this part of our business. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Over the past several years, we have expanded our service offerings into Canada and Australia, which have different market
drivers and seasonality as compared to the United States. In addition, our previous acquisitions of companies that provide pipeline logistics services to the natural gas and oil industry in the United States and various specialty services further
enhance the segment&#146;s service offerings, customer base and end markets. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The oil and gas industry is highly cyclical
and subject to volatility as a result of fluctuations in natural gas, natural gas liquids and oil prices. In the past, sustained periods of low prices for these products negatively impacted the development of related natural resources and
infrastructure. The challenging energy market environment over the past few years has adversely impacted demand for some of our services, primarily infrastructure services in Australia, Canada and the Gulf of Mexico.&nbsp;Exploration and production
companies and midstream companies also significantly reduced capital spending in response to the decline in oil and natural gas prices. Even though prices have recovered to a limited degree since early 2016, another meaningful decline or increased
uncertainty could result in additional reductions in capital spending on pipeline infrastructure, which would lessen demand for our services. In particular, the demand for infrastructure services in areas where the price of oil is influential, such
as Australia, the Canadian Oil Sands, certain oil-driven shale formations in the United States and offshore oil resources in the Gulf of Mexico, has been materially and adversely impacted by low oil prices. These markets could remain challenged if
oil prices remain at lower levels. We believe that, over the long term, the market should correct oversupply imbalances and prices could recover; however, the timing of any further recovery is uncertain. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Overall, we remain optimistic about this segment&#146;s operations going forward. From a near- and medium-term perspective, we
continue to believe that larger pipeline opportunities can provide significant profitability, although these projects and the profits they generate are often subject to more cyclicality and execution risk than our other service offerings. We have
also taken steps to diversify our operations in this segment through other services, such as pipeline integrity, pipeline logistics, and offshore specialty services. </P>

upgrade and expand electric power transmission infrastructure in order to improve system reliability and deliver renewable electricity from new generation sources to demand centers and from favorable industry legislation and regulations. We also
expect utilities to outsource more of their work to companies like us, due in part to the challenges associated with their aging workforces. We believe we are the partner of choice for many utilities in need of broad infrastructure expertise,
specialty equipment and workforce resources, particularly as capital budgets and infrastructure projects have become larger and more complex. </P> <P STYLE="font-size:12pt; margin-top:0pt; margin-bottom:0pt">&nbsp;</P>

high-bandwidth wireline and wireless services and applications is driving significant investment in wireline and wireless infrastructure in North America and Latin American to meet these demands and the deployment of new technologies. As a result of
these near and longer-term industry trends in the markets we serve, we believe there is meaningful demand for our communications engineering and construction services. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Though some of the markets and services in our Oil and Gas Infrastructure Services segment remain challenged, we believe
long-term dynamics create growth opportunities. In particular, we experienced backlog growth in 2016 primarily driven by new larger natural gas pipeline project awards and believe there could be similar activity over the next several years. We also
believe that our overall size and scope of service offerings allow us to leverage opportunities arising from the development of North American unconventional shale formations, the Canadian oil sands and coal seam gas and unconventional shale
formations in Australia. Further, the anticipated increase in demand for our pipeline integrity, rehabilitation and replacement services, and other services in adjacent markets, could create attractive growth potential for us and help diversify our
service offerings in both the near and long term. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Additionally, for both our electric power and oil and gas
infrastructure customers, through our strategic partnership approach and capital partnership structure, we have the financial strength to selectively and strategically provide financing and other solutions that could help facilitate development of
energy infrastructure projects and potentially create construction backlog for us. We believe changing regulations, industry trends and the increasing size of energy infrastructure projects and programs are creating and will continue to create such
opportunities, and our ability to selectively partner with customers in this manner is a competitive advantage. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Despite
our positive long-term outlook, competitive pricing environments, project delays and restrictive regulatory requirements have negatively impacted our margins in the past and could affect our margins in the future. Additionally, margins may be
negatively impacted on a quarterly basis due to adverse weather conditions, as well as timing of project starts or completions and other factors as previously described in <I>Understanding Margins</I>. We continue to focus on the elements of the
business that are largely within our control, including costs, the margins we accept on projects, collecting receivables, ensuring quality service, rightsizing initiatives as needed to match the markets we serve, and safely executing on the projects
we are awarded. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We also continue to evaluate potential strategic acquisitions and investments to broaden our customer
base, expand our geographic area of operation, grow our portfolio of services and increase opportunities across our operations. We believe that additional attractive acquisition candidates exist primarily as a result of the highly fragmented nature
of the industry, the inability of many companies to expand and modernize due to capital constraints, and the desire of owners for liquidity. We also believe that our financial strength, entrepreneurial operating model and experienced management team
are attractive to acquisition candidates. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Uncertainty of Forward-Looking Statements and Information </B></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">The information in this section should be read in connection with the information on financial market risk related to changes
in interest rates and currency exchange rates in Item&nbsp;7A. <I>Quantitative and Qualitative Disclosures About Market Risk </I>of Part II of our Annual Report on Form&nbsp;10-K for the year ended December&nbsp;31, 2016. Our primary exposure to
market risk relates to unfavorable changes in concentration of credit risk, interest rates and currency exchange rates. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Credit Risk.</I>&nbsp;We are subject to concentrations of credit risk related to our cash and cash equivalents and net
receivable position with customers, which includes amounts related to billed and unbilled accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts net of advanced billings with the same customer.
Substantially all of our cash and cash equivalents are managed by what we believe to be high credit quality financial institutions. In accordance with our investment policies, these institutions are authorized to invest cash and cash equivalents in
a diversified portfolio of what we believe to be high-quality investments, which primarily include interest-bearing demand deposits, money market investments and money market mutual funds with original maturities of three months or less. Although we
do not currently believe the principal amounts of these cash and cash equivalents are subject to any material risk of loss, changes in economic conditions could impact the interest income we receive from these investments. In addition, as we grant
credit under normal payment terms, generally without collateral, we are subject to potential credit risk related to our customers&#146; ability to pay for services provided. This risk may be heightened as a result of the depressed economic and
financial market conditions that have existed in recent years. However, we believe the concentration of credit risk related to billed and unbilled receivables and costs and estimated earnings in excess of billings on uncompleted contracts is limited
because of the diversity of our customers. We perform ongoing credit risk assessments of our customers and financial institutions and in some cases we obtain collateral or other security from our customers.<I> </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Interest Rate Risk. </I>As of March&nbsp;31, 2017, we had no derivative financial instruments to manage interest rate risk.
As such, we were exposed to earnings and fair value risk due to changes in interest rates with respect to our long-term obligations. As of March&nbsp;31, 2017, the fair value of our variable rate debt of $418.7 million approximated book value. Our
weighted average interest rate on our variable rate debt for the three months ended March&nbsp;31, 2017 was 2.61%. The annual effect on our pretax earnings of a hypothetical 50 basis point increase or decrease in variable interest rates would be
approximately $2.1 million based on our March&nbsp;31, 2017 balance of variable rate debt.<I> </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify"><I>Foreign Currency
Risk.</I>&nbsp;The U.S. dollar is the functional currency for the majority of our operations, which are primarily located within the United States. The functional currency for our foreign operations, which are primarily located in Canada and
Australia, is typically the currency of the country in which the foreign operating unit is located. Accordingly, our financial performance is subject to fluctuation due to changes in foreign currency exchange rates relative to the U.S. dollar.
During the three months ended March&nbsp;31, 2017, revenues from our foreign operations accounted for 30.1% of our consolidated revenues. Fluctuations in foreign exchange rates during the three months ended March&nbsp;31, 2017 caused an approximate
increase of $20 million in foreign revenues compared to the three months ended March&nbsp;31, 2016. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We are also subject
to foreign currency risk with respect to sales, purchases and borrowings that are denominated in a currency other than the respective functional currencies of our operating units. To minimize the risk from changes in foreign currency exchange rates,
we may enter into foreign currency derivative contracts to hedge our foreign currency risk on a cash flow basis. There were no outstanding foreign currency derivative contracts at March&nbsp;31, 2017. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">We also have foreign exchange risk related to cash and cash equivalents in foreign banks. Based on the balance of cash and
cash equivalents in foreign banks of $89.0 million as of March&nbsp;31, 2017, an assumed 5% adverse change to foreign exchange rates would result in a fair value decline of $4.5 million. Fluctuations in fair value are recorded in &#147;Accumulated
other comprehensive income (loss),&#148; a separate component of stockholders&#146; equity. </P>

Officer, as appropriate to allow timely decisions regarding required disclosure. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">As of the end of the period covered by
this Quarterly Report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule&nbsp;13a-15(b) of the Exchange Act. This evaluation was carried out under the supervision and with the
participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, these officers have concluded that, as of March&nbsp;31, 2017, our disclosure controls and procedures were effective to
provide reasonable assurance of achieving their objectives. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Internal Control over Financial Reporting </B></P>

of Control Systems </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" ALIGN="justify">Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect
that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute,
assurance that the control system&#146;s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of
the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been
detected. These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because of simple errors or mistakes. Controls can be circumvented by the individual acts of some persons, by
collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will
succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. </P>

 restricted stock, restricted stock units (RSUs) and performance
 units to be settled in common stock based on the fair value of the
 awards at the date of grant, net of estimated forfeitures. The fair
 value of restricted stock awards, RSUs and performance units to be
 settled in common stock is determined based on the number of
 shares, RSUs or performance units granted and the closing price of
 Quanta&amp;#x2019;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 recognized as compensation expense.
 The resulting compensation expense from time-based RSU and
 performance unit 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 RSU
 awards is recognized using the graded vesting method over the
 requisite service period. Payments made by Quanta to satisfy
 employees&amp;#x2019; tax withholding obligations associated with awards
 settled in common stock are classified as financing cash flows.&lt;/p&gt;

 based awards, such as RSUs that are expected to or may settle in
 cash, is recognized based on a remeasurement of the fair value of
 the award at the end of each reporting period. Upon settlement, the
 holders receive for each RSU an amount in cash equal to the fair
 market value on the settlement date of one share of Quanta common
 stock, as specified in the applicable award agreement. For

 historical acquisitions of companies. Upon acquisition, these
 companies were either combined into one of Quanta&amp;#x2019;s existing
 operating units or managed on a stand-alone basis as an individual
 operating unit. Goodwill recorded in connection with these
 acquisitions is subject to an annual assessment for impairment,
 which Quanta performs at the operating unit level for each
 operating unit that carries a balance of goodwill. Each of
 Quanta&amp;#x2019;s operating units is organized into one of two
 internal divisions: the Electric Power Infrastructure Services
 Division and the Oil and Gas Infrastructure Services Division. As
 most of the companies acquired by Quanta provide multiple types of
 services for multiple types of customers, these divisional
 designations are based on the predominant type of work performed by
 each operating unit at the point in time the divisional designation
 is made. Goodwill is required to be measured for impairment at the
 reporting unit level, which represents the operating segment level
 or one level below the operating segment level for which discrete
 financial information is available. Quanta has determined that its
 individual operating units represent its reporting units for the
 purpose of assessing goodwill impairments.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;Quanta has the option to first assess qualitative
 factors to determine whether it is necessary to perform the
 two-step fair value-based impairment test described below. If
 Quanta 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. Quanta can
 choose to perform the qualitative assessment on none, some or all
 of its reporting units. Quanta 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 the
 qualitative assessment in any subsequent period. Qualitative
 indicators including deterioration in macroeconomic conditions,
 declining financial performance, or a sustained decrease in share
 price, among other things, may trigger the need for annual or
 interim impairment testing of goodwill associated with one or all
 of the reporting units.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;Quanta&amp;#x2019;s goodwill impairment assessment is
 performed at year-end, or more frequently if events or
 circumstances arise which indicate that goodwill may be impaired.
 For instance, a decrease in Quanta&amp;#x2019;s market capitalization
 below book value, a significant change in business climate or loss
 of a significant customer, as well as the qualitative indicators
 referenced above, may trigger the need for interim impairment
 testing of goodwill for 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&amp;#x2019;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&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;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&amp;#x2019;s opinion, this method currently results in the
 most accurate calculation of a reporting unit&amp;#x2019;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, among others, revenue growth
 rates, operating margins, discount rates, weighted average costs of
 capital and future market conditions. 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.&lt;/p&gt;

 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
 one-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&amp;#x2019;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.&lt;/p&gt;

 approaches, Quanta determines the estimated fair value of each of
 its reporting units by applying transaction multiples to each
 reporting unit&amp;#x2019;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.&lt;/p&gt;

 impairment test may indicate an implied fair value that is
 substantially similar to the reporting unit&amp;#x2019;s carrying value.
 Such similarities in value are generally an indication that
 management&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;During the fourth quarter of 2016, a two-step
 fair-value based goodwill impairment analysis was performed for
 each of Quanta&amp;#x2019;s reporting units, and no reporting units were
 evaluated solely on a qualitative basis. Step one of the analysis
 indicated that the implied fair value of each of Quanta&amp;#x2019;s
 reporting units, other than recently acquired reporting units and
 the reporting units that recorded goodwill impairment charges in
 2015, was substantially in excess of its carrying value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;As discussed generally above, when evaluating the
 2016 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&amp;#x2019;s reporting units were operating.
 Additionally, management considered the sensitivity of its fair
 value estimates to changes in certain valuation assumptions. After
 taking into account a 10% decrease in the fair value of each of
 Quanta&amp;#x2019;s reporting units, two reporting units within
 Quanta&amp;#x2019;s Oil and Gas Infrastructure Division had fair values
 below their respective carrying values. Quanta recorded asset
 impairment charges for these reporting units in 2015. The fair
 values determined in 2016 for these reporting units were consistent
 with the fair values determined in 2015, accordingly the fair
 values approximate the current carrying values. Circumstances such
 as market declines, unfavorable economic conditions, the loss of a
 major customer or other factors could increase the risk of
 impairment of goodwill in future periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;If an operating unit experiences prolonged periods
 of declining revenues, operating margins or both, it may be at risk
 of failing step one of the goodwill impairment test. Certain
 operating units have experienced declines over the short-term due
 to challenging macroeconomic conditions in certain geographic areas
 and low oil and natural gas prices, which have negatively impacted
 customer spending and resulted in project cancellations and delays.
 Additionally, customer capital spending has been constrained as a
 result of an increasingly complex regulatory and permitting
 environment. Certain operating units within Quanta&amp;#x2019;s Oil and
 Gas Infrastructure Services Division that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors. Goodwill and intangible
 assets associated with the operating units within Quanta&amp;#x2019;s
 Oil and Gas Infrastructure Services Division that have been
 significantly impacted by the factors mentioned above were $69.8
 million and $11.7 million at March&amp;#xA0;31, 2017. Quanta monitors
 these conditions and others to determine if it is necessary to
 perform step one of the fair-value based impairment test for one or
 more operating units prior to the annual impairment assessment. No
 interim impairment charges were recorded during the three months
 ended March&amp;#xA0;31, 2017. Although Quanta is not aware of
 circumstances that would lead to a goodwill impairment at a
 reporting unit currently, circumstances such as a continued market
 decline, the loss of a major customer or other factors could impact
 the valuation of goodwill in the future.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;Quanta&amp;#x2019;s intangible assets include customer
 relationships, backlog, trade names, non-compete agreements,
 patented rights and developed technology, all subject to
 amortization. The value of customer relationships is estimated as
 of the date a business is acquired based on 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 and estimated customer attrition rates, the
 importance or lack thereof of existing customer relationships to
 Quanta&amp;#x2019;s business plan, income taxes and required rates of
 return. Quanta values backlog for acquired businesses as of the
 acquisition date 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;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.&lt;/p&gt;

 amended and restated credit agreement with various lenders that
 provides for a $1.81 billion senior secured revolving credit
 facility maturing on December&amp;#xA0;18, 2020. The entire amount
 available under the facility may be used by Quanta for revolving
 loans and letters of credit in U.S. dollars and certain alternative
 currencies. Up to $600.0 million of the facility may be used by
 certain subsidiaries of Quanta for revolving loans and letters of
 credit in certain alternative currencies. Up to $100.0 million of
 the facility may be used for swing line loans in U.S. dollars, up
 to $50.0 million of the facility may be used for swing line loans
 in Canadian dollars and up to $30.0 million of the facility may be
 used for swing line loans in Australian dollars. In addition,
 subject to the conditions specified in the credit agreement, Quanta
 has the option to increase the revolving commitments by up to
 $400.0 million from time to time upon receipt of additional
 commitments from new or existing lenders. Borrowings under the
 credit agreement are to be used to refinance existing indebtedness
 and for working capital, capital expenditures and other general
 corporate purposes.&lt;/p&gt;

 determined based on Quanta&amp;#x2019;s Consolidated Leverage Ratio (as
 described below), or (ii)&amp;#xA0;the Base Rate (as described below)
 plus 0.125% to 1.125%, as determined based on Quanta&amp;#x2019;s
 Consolidated Leverage Ratio. Amounts borrowed as revolving loans
 under the credit agreement in any currency other than U.S. dollars
 bear interest at a rate equal to the Eurocurrency Rate plus 1.125%
 to 2.125%, as determined based on Quanta&amp;#x2019;s Consolidated
 Leverage Ratio. Standby letters of credit issued under the credit
 agreement are subject to a letter of credit fee of 1.125% to
 2.125%, based on Quanta&amp;#x2019;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 0.675% to
 1.275%, based on Quanta&amp;#x2019;s Consolidated Leverage Ratio. Quanta
 is also subject to a commitment fee of 0.20% to 0.40%, based on its
 Consolidated Leverage Ratio, on any unused availability under the
 credit agreement.&lt;/p&gt;

 purposes of calculating Quanta&amp;#x2019;s Consolidated Leverage Ratio,
 Consolidated Funded Indebtedness is reduced by available cash and
 Cash Equivalents (as defined in the credit agreement) in excess of
 $25.0 million. The Base Rate equals the highest of (i)&amp;#xA0;the
 Federal Funds Rate (as defined in the credit agreement) plus 0.5%,

 subsidiaries and 65% of the capital stock of direct foreign
 subsidiaries of Quanta&amp;#x2019;s wholly owned U.S. subsidiaries.
 Quanta&amp;#x2019;s wholly owned U.S. subsidiaries also guarantee the
 repayment of all amounts due under the credit agreement. Subject to
 certain conditions, all collateral will automatically be released
 from the liens at any time Quanta maintains an Investment Grade
 Rating (defined in the credit agreement as two of the following
 three conditions being met: (i)&amp;#xA0;a corporate credit rating that
 is BBB- or higher by Standard&amp;#xA0;&amp;amp; Poor&amp;#x2019;s Rating
 Services, (ii)&amp;#xA0;a corporate family rating that is Baa3 or

 Consolidated Interest Coverage Ratio (as defined in the credit
 agreement). The credit agreement also limits certain acquisitions,
 mergers and consolidations, indebtedness, asset sales and
 prepayments of indebtedness and, subject to certain exceptions,
 prohibits liens on Quanta&amp;#x2019;s assets. The credit agreement
 allows cash payments for dividends and stock repurchases subject to
 compliance with the following requirements (after giving effect to
 the dividend or stock repurchase): (i)&amp;#xA0;no default or event of
 default under the credit agreement; (ii)&amp;#xA0;continued compliance
 with the financial covenants in the credit agreement; and
 (iii)&amp;#xA0;at least $100.0 million of availability under the credit
 agreement and/or cash and cash equivalents on hand. As of
 March&amp;#xA0;31, 2017, Quanta was in compliance with all of the
 covenants in the credit agreement.&lt;/p&gt;

 agreement with its sureties and all of Quanta&amp;#x2019;s other debt
 instruments exceeding $100.0 million in borrowings or availability.
 If an Event of Default (as defined in the credit agreement) occurs
 and is continuing, on the terms and subject to the conditions set
 forth in the credit agreement, the lenders may declare all amounts
 outstanding and accrued and unpaid interest immediately due and
 payable, require that Quanta provide cash collateral for all
 outstanding letter of credit obligations, terminate the commitments
 under the credit agreement, and foreclose on the collateral.&lt;/p&gt;

 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&amp;#x2019;s investments in joint ventures, which are
 either consolidated or proportionately consolidated, as discussed
 in the following summary of significant accounting policies.
 Investments in affiliated entities in which Quanta does not have a
 controlling financial interest, but over which Quanta has
 significant influence, usually because Quanta holds a voting
 interest of between 20% and 50%, are accounted for using the equity
 method. All significant intercompany accounts and transactions have
 been eliminated in consolidation. Unless the context requires
 otherwise, references to Quanta include Quanta Services, Inc. and
 its consolidated subsidiaries.&lt;/p&gt;

 million and $112.2 million as of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016. Cash consisting of interest-bearing demand
 deposits is carried at cost, which approximates fair value. Quanta
 considers all highly liquid investments with an original maturity
 of three months or less at the time of purchase to be cash
 equivalents, which are carried at fair value. At March&amp;#xA0;31,
 2017 and December&amp;#xA0;31, 2016, cash equivalents were $8.1 million
 and $8.8 million, and consisted primarily of money market
 investments and money market mutual funds and are discussed further

 2017 and December&amp;#xA0;31, 2016, cash and cash equivalents held in
 domestic bank accounts were $17.5 million and $19.5 million, and
 cash and cash equivalents held in foreign bank accounts were $89.0
 million and $92.7 million. As of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016, cash and cash equivalents held by
 Quanta&amp;#x2019;s investments in joint ventures, which are either
 consolidated or proportionately consolidated, were $8.8 million and
 $11.5 million, of which $7.7 million and $10.0 million related to
 domestic joint ventures. Cash and cash equivalents held by the
 joint ventures are available to support the operations of the
 related joint ventures, but Quanta does not have access to that
 cash and cash equivalents for its other operations. Under the terms
 of the partnership agreements, Quanta generally has no right to the
 joint ventures&amp;#x2019; cash and cash equivalents other than
 participating in distributions and in the event of dissolution.&lt;/p&gt;

 approved the 2011 Omnibus Equity Incentive Plan (the 2011 Plan).
 The 2011 Plan provides for the award of non-qualified stock
 options, incentive (qualified) stock options, stock appreciation
 rights, restricted stock, RSUs, stock bonus awards, performance
 compensation awards (including performance units and cash bonus
 awards) or any combination of the foregoing. The purpose of the
 2011 Plan is to attract and retain key personnel and provide
 participants with additional performance incentives by increasing
 their proprietary interest in Quanta. Employees, directors,
 officers, consultants or advisors of Quanta or its affiliates are
 eligible to participate in the 2011 Plan, as are prospective
 employees, directors, officers, consultants or advisors of Quanta
 who have agreed to serve Quanta in those capacities. An aggregate
 of 11,750,000 shares of Quanta common stock may be issued pursuant
 to awards granted under the 2011 Plan.&lt;/p&gt;

 2007 Stock Incentive Plan (the 2007 Plan), which was adopted on
 May&amp;#xA0;24, 2007, Quanta may award restricted stock, incentive
 stock options and non-qualified stock options to eligible
 employees, directors, and certain consultants and advisors. An
 aggregate of 4,000,000 shares of common stock may be issued
 pursuant to awards granted under the 2007 Plan, and the 2007 Plan
 terminates on May&amp;#xA0;24, 2017. Quanta also has a Restricted Stock
 Unit Plan (the RSU Plan), pursuant to which RSUs may be awarded to
 certain employees and consultants of Quanta&amp;#x2019;s Canadian
 operations.&lt;/p&gt;

 to be settled in common stock under the Plans with weighted average
 grant date fair values of $38.18 and $21.95. The grant date fair
 value for awards of restricted stock and RSUs to be settled in
 common stock is based on the market value of Quanta common stock on
 the date of grant. Restricted stock and RSU awards to be settled in
 common stock are subject to forfeiture, restrictions on transfer
 and certain other conditions until vesting, which generally occurs
 in equal installments over a two-year or three-year period
 following the date of grant. During the restriction period, holders
 of restricted stock are entitled to vote and receive dividends on
 such shares.&lt;/p&gt;

 RSUs to be settled in common stock. As of March&amp;#xA0;31, 2017,
 there was $54.0 million of total unrecognized compensation cost
 related to unvested RSUs to be settled in common stock granted to
 both employees and non-employees. This cost is expected to be

 These performance units cliff-vest at the end of a three-year
 performance period based on achievement of company performance
 goals established by Quanta&amp;#x2019;s compensation committee. The
 final amount of earned and vested performance units can range from

 achievement of such goals, as determined by Quanta&amp;#x2019;s

 performance units to be settled in common stock under the 2011 Plan

 is based on the market value of Quanta common stock on the date of
 grant applied to the total number of performance units that Quanta
 anticipates will become earned and vest.&amp;#xA0;This fair value is
 expensed ratably over the three-year performance period and is
 adjusted for fair value changes, so that the expense recognized is
 equivalent to the fair value of the final number of earned and
 vested performance units.&amp;#xA0;During the three months ended
 March&amp;#xA0;31, 2017 and 2016, Quanta recognized $0.7 million and

 settled solely in cash. These cash-settled RSUs are intended to
 provide plan participants with cash performance incentives that are
 substantially equivalent to the risks and rewards of equity
 ownership in Quanta, typically vest in equal installments over a
 two-year or three-year period following the date of grant, and are
 subject to forfeiture under certain conditions, primarily
 termination of service. Additionally, subject to certain
 restrictions, Quanta&amp;#x2019;s non-employee directors may elect to
 cash settle a portion of their RSU awards, which generally vest
 upon conclusion of the director service year. For all RSUs settled
 in cash, the holders receive for each vested RSU an amount in cash
 equal to the fair market value of one share of Quanta common stock
 on the settlement date, as specified in the applicable award
 agreement.&lt;/p&gt;

 in cash was $2.7 million and $1.5 million for the three months

 selling, general and administrative expenses. RSUs that are
 anticipated to be settled in cash are not included in the
 calculation of earnings per share, and the estimated earned value
 of such RSUs is classified as a liability. Quanta paid $2.4 million
 and $1.0 million to settle liabilities related to cash-settled RSUs
 in the three months ended March&amp;#xA0;31, 2017 and 2016. Accrued
 liabilities for the estimated earned value of outstanding RSUs to

 Securities and Exchange Commission (SEC). Certain information and

 statements prepared in accordance with accounting principles
 generally accepted in the United States (US GAAP), have been
 condensed or omitted pursuant to those rules and regulations.
 Quanta believes that the disclosures made are adequate to make the

 all adjustments, consisting only of normal recurring adjustments,
 necessary to fairly state the financial position, results of

 &lt;b&gt;&lt;i&gt;Functional Currency and Translation of Financial
 Statements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;The U.S. dollar is the functional currency for the
 majority of Quanta&amp;#x2019;s operations, which are primarily located
 within the United States. The functional currency for
 Quanta&amp;#x2019;s foreign operations, which are primarily located in
 Canada and Australia, is typically the currency of the country in
 which the foreign operating unit is located. Generally, the
 currency in which the operating unit transacts the majority of its
 activities, including billings, financing, payroll and other
 expenditures, would be considered the functional currency. The
 treatment of foreign currency translation gains or losses is
 dependent upon management&amp;#x2019;s determination of the functional
 currency of each 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, comprehensive income and
 cash flows are translated at average monthly rates, while balance
 sheets are translated at month-end exchange rates. The translation
 of the balance sheet results in translation gains or losses, which
 are included as a separate component of equity under the caption
 &amp;#x201C;Accumulated other comprehensive income (loss).&amp;#x201D; Gains
 and losses arising from transactions which are not denominated in
 the operating units&amp;#x2019; functional currencies are included
 within other income (expense) in the statements of operations.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;As described in Note&amp;#xA0;8, Quanta holds
 investments in certain joint ventures with third parties for the
 purpose of providing infrastructure services under certain customer
 contracts. Losses incurred by these joint ventures are generally
 shared ratably based on the percentage ownership of the joint
 venture members. However, each member of the joint venture
 typically is jointly and severally liable for all of the
 obligations of the joint venture under the contract with the
 customer, and therefore can be liable for full performance of the
 contract with the customer. In circumstances where Quanta&amp;#x2019;s
 participation in a joint venture qualifies as a general
 partnership, the joint venture partners are jointly and severally
 liable for all of the obligations of the joint venture, including
 obligations owed to the customer or any other person or entity.
 Quanta is not aware of circumstances that would lead to future
 claims against it for material amounts in connection with these
 joint and several liabilities.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In the joint venture arrangements entered into by
 Quanta, typically each joint venture party indemnifies the other
 party for any liabilities incurred in excess of the liabilities
 such other party is obligated to bear under the respective joint
 venture agreement. It is possible, however, that Quanta could be
 required to pay or perform obligations in excess of its share if
 the other party to the joint venture failed or refused to pay or
 perform its share of the obligations. Quanta is not aware of
 circumstances that would lead to future claims against it for
 material amounts that would not be indemnified.&lt;/p&gt;

 substations. Quanta will provide turnkey EPC services for the
 entire project. As of March&amp;#xA0;31, 2017, Quanta had made
 aggregate contributions to this unconsolidated affiliate of $16.9
 million and had received $2.9 million as a return of capital. Also

 million and $56.4 million for the three months ended March&amp;#xA0;31,

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta has guaranteed the residual value on certain
 of its equipment operating leases. Quanta has agreed to pay any
 difference between this residual value and the fair market value of
 the underlying asset at the date of termination of the leases. At
 March&amp;#xA0;31, 2017, the maximum guaranteed residual value was
 $573.3&amp;#xA0;million. Quanta believes that no significant payments
 will be made as a result of the difference between the fair market
 value of the leased equipment and the guaranteed residual value.
 However, there can be no assurance that significant payments will
 not be required in the future.&lt;/p&gt;

 its vehicle fleet in order to accommodate manufacturer lead times
 on certain types of vehicles. As of March&amp;#xA0;31, 2017, Quanta had
 issued $20.3 million of production orders with expected delivery
 dates in 2017. Although Quanta has committed to purchase these
 vehicles at the time of their delivery, Quanta anticipates that
 these orders will be assigned to third party leasing companies and
 made available to Quanta under certain of its master equipment
 lease agreements, thereby releasing Quanta from its capital
 commitments.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Legal Proceedings&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta is from time to time party to various
 lawsuits, claims and other legal proceedings that arise in the
 ordinary course of business. These actions typically seek, among
 other things, compensation for alleged personal injury, breach of
 contract and/or property damages, employment-related damages,
 punitive damages, civil penalties or other losses, or injunctive or
 declaratory relief. With respect to all such lawsuits, claims and
 proceedings, Quanta records a reserve when it is probable that a
 liability has been incurred and the amount of loss can be
 reasonably estimated. In addition, Quanta discloses matters for
 which management believes a material loss is at least reasonably
 possible. Except as otherwise stated below, none of these
 proceedings, separately or in the aggregate, are expected to have a
 material adverse effect on Quanta&amp;#x2019;s consolidated financial
 position, results of operations or cash flows. In all instances,
 management has assessed the matter based on current information and
 made a judgment concerning its potential outcome, giving due
 consideration to the nature of the claim, the amount and nature of
 damages sought and the probability of success. Management&amp;#x2019;s
 judgment may prove materially inaccurate, and such judgment is made
 subject to the known uncertainties of litigation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;&lt;i&gt;Lorenzo Benton v. Telecom Network Specialists,
 Inc., et al.&lt;/i&gt;&amp;#xA0;In June 2006, plaintiff Lorenzo Benton filed
 a class action complaint in the Superior Court of California,
 County of Los Angeles, alleging various wage and hour violations
 against Telecom Network Specialists (TNS), a former subsidiary of
 Quanta.&amp;#xA0;Quanta retained liability associated with this matter
 pursuant to the terms of Quanta&amp;#x2019;s sale of TNS in December
 2012. Benton seeks to represent a class of workers that includes
 all persons who worked on certain TNS projects, including
 individuals that TNS retained through numerous staffing
 agencies.&amp;#xA0;The plaintiff class in this matter is seeking
 damages for unpaid wages, penalties associated with the failure to
 provide meal and rest periods and overtime wages, interest and
 attorneys&amp;#x2019; fees. In September 2015, the trial court certified
 the class as to workers from the various staffing companies at
 issue. In January 2017, the trial court granted a summary judgment
 motion filed by the plaintiff class and found that TNS was a joint
 employer of the class members and that it failed to provide
 adequate meal and rest breaks and failed to pay overtime wages.
 Quanta believes this decision is not supported by controlling law
 and continues to contest liability in this matter.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Additionally, in November 2007, TNS filed cross
 complaints for indemnity and breach of contract against the
 staffing agencies, which employed many of the individuals in
 question. In December 2012, the trial court heard cross-motions for
 summary judgment filed by TNS and the staffing agencies pertaining
 to TNS&amp;#x2019;s demand for indemnity.&amp;#xA0;The court denied
 TNS&amp;#x2019;s motion and granted the motions filed by the staffing
 agencies; however, the California Appellate Court reversed the
 trial court&amp;#x2019;s decision in part and instructed the trial court
 to reconsider its ruling.&amp;#xA0;In February 2017, the court denied a
 new motion for summary judgment filed by the staffing companies and
 stated that the staffing companies were liable to TNS for any
 damages owed to the class members that the staffing companies
 employed.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The final amount of liability, if any, payable in
 connection with this matter remains the subject of pending
 litigation and will ultimately depend on various factors, including
 the outcome of Quanta&amp;#x2019;s appeal of the trial court&amp;#x2019;s
 ruling and the solvency of the staffing agencies. Based on review
 and analysis of the trial court&amp;#x2019;s rulings, Quanta does not
 believe, at this time, that it is probable this matter will result
 in a material loss; however, a loss up to approximately $23 million
 remains reasonably possible upon final resolution of this
 matter.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Concentrations of Credit Risk&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta is subject to concentrations of credit risk
 related primarily to its cash and cash equivalents and net
 receivable position with customers, which includes amounts related
 to billed and unbilled accounts receivable and costs and estimated
 earnings in excess of billings on uncompleted contracts net of
 advanced billings with the same customer. Substantially all of
 Quanta&amp;#x2019;s cash and cash equivalents are managed by what it
 believes to be high credit quality financial institutions. In
 accordance with Quanta&amp;#x2019;s investment policies, these
 institutions are authorized to invest cash and cash equivalents in
 a diversified portfolio of what Quanta believes to be high quality
 cash and cash equivalent investments, which consist primarily of
 interest-bearing demand deposits, money market investments, 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 cash and cash
 equivalents is subject to any material risk of loss, changes in
 economic conditions could impact the interest income Quanta
 receives from these investments. In addition, Quanta grants credit
 under normal payment terms, generally without collateral, to its
 customers, which include electric power and oil and gas companies,
 governmental entities, general contractors, and builders, owners
 and managers of commercial and industrial properties located
 primarily in the United States, Canada and Australia. Consequently,
 Quanta is subject to potential credit risk related to changes in
 business and economic factors throughout the United States, Canada
 and Australia, which may be heightened as a result of uncertain
 economic and financial market conditions that have existed in
 recent years. However, Quanta generally has certain statutory lien
 rights with respect to services provided. Historically, some of
 Quanta&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;At March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016,
 one customer within Quanta&amp;#x2019;s Electric Power Infrastructure
 Services segment accounted for approximately 16% of Quanta&amp;#x2019;s
 consolidated net receivable position. The net receivable position
 for this customer was $300.4 million and $277.3 million at
 March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016 and was related to
 two electric transmission projects located in remote regions of
 northeastern Canada. Included in the net receivable position for
 this customer were $191.1 million and $175.9 million of costs and
 estimated earnings in excess of billings on uncompleted contracts
 at March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016. These net
 receivable balances were related to invoicing challenges and
 billing delays that resulted from extensive quality assurance
 documentation and administrative requirements. Quanta continues to
 work collaboratively with the customer to improve these processes.
 The net receivable position also included change orders and claims
 that Quanta is negotiating in the normal course of business. No
 other customers represented 10% or more of Quanta&amp;#x2019;s
 consolidated net receivable position as of March&amp;#xA0;31, 2017 or
 December&amp;#xA0;31, 2016.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Additionally, two customers within Quanta&amp;#x2019;s
 Oil and Gas Infrastructure Services segment each accounted for
 approximately 10% of Quanta&amp;#x2019;s consolidated revenues during
 the three months ended March&amp;#xA0;31, 2017. No other customers
 represented 10% or more of Quanta&amp;#x2019;s consolidated revenues for
 the three months ended March&amp;#xA0;31, 2017, and no customers
 represented 10% or more of Quanta&amp;#x2019;s consolidated revenues for
 the three months ended March&amp;#xA0;31, 2016.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;As discussed in Note 2, Quanta is insured for
 employer&amp;#x2019;s liability, workers&amp;#x2019; compensation, auto
 liability, general liability and group health claims. As of
 March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016, the gross amount
 accrued for insurance claims totaled $220.0 million and $218.2
 million with $162.1 million and $162.0 million considered to be
 long-term and included in other non-current liabilities. Related
 insurance recoveries/receivables as of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016 were $8.1 million and $8.7 million, of which
 $0.4 million and $0.4&amp;#xA0;million were included in prepaid
 expenses and other current assets and $7.7 million and $8.3 million
 were included in other assets, net.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Letters of Credit&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Certain of Quanta&amp;#x2019;s vendors require letters
 of credit to ensure reimbursement for amounts they are disbursing
 on Quanta&amp;#x2019;s behalf, such as to beneficiaries under its
 self-funded insurance programs. In addition, from time to time,
 certain customers require Quanta to post letters of credit to
 ensure payment to its subcontractors and vendors and to guarantee
 performance under contracts. Such letters of credit are generally
 issued by a bank or similar financial institution, typically
 pursuant to Quanta&amp;#x2019;s credit facility. Each 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.
 Depending on the circumstances of such a reimbursement, Quanta may
 also be required to record a charge to earnings for the
 reimbursement. Quanta does not believe that it is likely that any
 material claims will be made under a letter of credit in the
 foreseeable future.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As of March&amp;#xA0;31, 2017, Quanta had $323.2
 million in outstanding letters of credit and bank guarantees under
 its credit facility to secure its casualty insurance program and
 various contractual commitments. These are irrevocable stand-by
 letters of credit with maturities generally expiring at various
 times throughout 2017 and 2018. Upon maturity, it is expected that
 the majority of the letters of credit related to the casualty
 insurance program will be renewed for subsequent one-year
 periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Performance Bonds and Parent Guarantees&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;In certain circumstances, Quanta is required to
 provide performance bonds in connection with its contractual
 commitments. Quanta has indemnified its sureties for any expenses
 paid out under these performance bonds. These performance bonds
 expire at various times ranging from mechanical completion of the
 related projects to a period extending beyond contract completion
 in certain circumstances, and as such a determination of maximum
 potential amounts outstanding requires the use of certain estimates
 and assumptions. Such amounts can also fluctuate from period to
 period based upon the mix and level of Quanta&amp;#x2019;s bonded
 operating activity. As of March&amp;#xA0;31, 2017, the total amount of
 the outstanding performance bonds was estimated to be approximately
 $3.4&amp;#xA0;billion. Quanta&amp;#x2019;s estimated maximum exposure as it
 relates to the value of the performance bonds outstanding is
 lowered on each bonded project as the cost to complete is reduced,
 and each of its commitments under the performance bonds generally
 extinguishes concurrently with the expiration of its related
 contractual obligation. The estimated cost to complete these bonded
 projects was approximately $910 million as of March&amp;#xA0;31,
 2017.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Additionally, from time to time, Quanta guarantees
 the obligations of its wholly owned subsidiaries, including
 obligations under certain contracts with customers, certain lease
 obligations and, in some states, obligations in connection with
 obtaining contractors&amp;#x2019; licenses. Quanta is not aware of any
 material obligations for performance or payment asserted against it

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta has various employment agreements with
 certain executives and other employees, which provide for
 compensation and certain other benefits and for severance payments
 under certain circumstances. Certain employment agreements also
 contain clauses that become effective upon a change in control of
 Quanta, and Quanta may be obligated to pay certain amounts to such
 employees upon the occurrence of any of the defined change in
 control events.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Collective Bargaining Agreements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Some of Quanta&amp;#x2019;s operating units are parties
 to various collective bargaining agreements with unions that
 represent certain of their employees. The collective bargaining
 agreements expire at various times and have typically been
 renegotiated and renewed on terms similar to those in the expiring
 agreements. From time to time, Quanta is a party to grievance
 actions based on claims arising out of the collective bargaining
 agreements. The agreements require the operating units to pay
 specified wages, provide certain benefits to their union employees
 and contribute certain amounts to multiemployer pension plans and
 employee benefit trusts. Quanta&amp;#x2019;s multiemployer pension plan
 contribution rates generally are specified in the collective
 bargaining agreements (usually on an annual basis), and
 contributions are made to the plans on a
 &amp;#x201C;pay-as-you-go&amp;#x201D; basis based on its union employee
 payrolls. The location and number of union employees that Quanta
 employs at any given time and the plans in which they may
 participate vary depending on the projects Quanta has ongoing at
 any time and the need for union resources in connection with those
 projects. Therefore, Quanta is unable to accurately predict its
 union employee payroll and the amount of the resulting
 multiemployer pension plan contribution obligation for future
 periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The Pension Protection Act of 2006 (PPA) also added
 special funding and operational rules generally applicable to plan
 years beginning after 2007 for multiemployer plans that are
 classified as &amp;#x201C;endangered,&amp;#x201D; &amp;#x201C;seriously
 endangered&amp;#x201D; or &amp;#x201C;critical&amp;#x201D; status based on
 multiple factors (including, for example, the plan&amp;#x2019;s funded
 percentage, cash flow position and whether it is projected to
 experience a minimum funding deficiency). Plans in these
 classifications must adopt measures to improve their funded status
 through a funding improvement or rehabilitation plan, as
 applicable, which may require additional contributions from
 employers (which may take the form of a surcharge on benefit
 contributions) and/or modifications to retiree benefits. Certain
 plans to which Quanta contributes or may contribute in the future
 are in &amp;#x201C;endangered,&amp;#x201D; &amp;#x201C;seriously endangered&amp;#x201D;
 or &amp;#x201C;critical&amp;#x201D; status. The amount of additional funds,
 if any, that Quanta may be obligated to contribute to these plans
 in the future cannot be estimated due to uncertainty of the future
 levels of work that require the specific use of union employees
 covered by these plans, as well as the future contribution levels
 and possible surcharges on contributions applicable to these
 plans.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta may be subject to additional liabilities
 imposed by law as a result of its participation in multiemployer
 defined benefit pension plans. For example, the Employee Retirement
 Income Security Act of 1974, as amended by the Multiemployer
 Pension Plan Amendments Act of 1980, imposes certain liabilities
 upon an employer who is a contributor to a multiemployer pension
 plan if the employer withdraws from the plan or the plan is
 terminated or experiences a mass withdrawal. These liabilities
 include an allocable share of the unfunded vested benefits in the
 plan for all plan participants, not merely the benefits payable to
 a contributing employer&amp;#x2019;s own retirees. As a result,
 participating employers may bear a higher proportion of liability
 for unfunded vested benefits if other participating employers cease
 to contribute or withdraw, with the reallocation of liability being
 more acute in cases when a withdrawn employer is insolvent or
 otherwise fails to pay its withdrawal liability. Other than as
 described below, Quanta is not aware of any material amounts of
 withdrawal liability that have been incurred as a result of a
 withdrawal by any of Quanta&amp;#x2019;s operating units from any
 multiemployer defined benefit pension plans.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;&lt;i&gt;2011 Central States Plan Withdrawal
 Liability.&lt;/i&gt; In the fourth quarter of 2011, certain Quanta
 subsidiaries withdrew from the Central States, Southeast and
 Southwest Areas Pension Plan (the Central States Plan). This
 withdrawal event was the result of an amendment to a collective
 bargaining agreement with the International Brotherhood of
 Teamsters (Teamsters) that eliminated certain employers&amp;#x2019;
 obligations to contribute to the Central States Plan, which was
 then in critical status and significantly underfunded as to its
 vested benefit obligations. The amendment was negotiated by the
 Pipe Line Contractors Association (PLCA) on behalf of its members,
 which include certain Quanta subsidiaries. Because certain other
 Quanta subsidiaries continued participation in the Central States
 Plan into 2012, the Quanta subsidiaries&amp;#x2019; withdrawals in 2011
 effected only a partial withdrawal on behalf of Quanta for 2011.
 Quanta believed that the partial withdrawal was advantageous
 because it limited exposure to increased liability resulting from a
 future withdrawal event, at which point the Central States Plan
 could have been further underfunded. Quanta and other PLCA members
 now contribute to a different multiemployer pension plan on behalf
 of the affected Teamsters employees. While certain additional
 Quanta subsidiaries continued participation in the Central States
 Plan into 2012, Quanta believes that such subsidiaries withdrew
 from the Central States Plan in 2012, thereby effecting a complete
 withdrawal as of December&amp;#xA0;30, 2012 for all Quanta
 subsidiaries.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In connection with the partial withdrawal in 2011,
 Quanta recorded a withdrawal liability of approximately $32.6
 million in the fourth quarter of 2011 based on estimates received
 from the Central States Plan. The Central States Plan subsequently
 asserted that the withdrawal of the PLCA members, and thus
 Quanta&amp;#x2019;s partial withdrawal, was not effective in 2011. The
 PLCA and Quanta believed at that time that a legally effective
 withdrawal had occurred during the fourth quarter of 2011, and this
 issue was litigated in the federal district court for the Northern
 District of Illinois, Eastern Division. In September 2013, the
 district court ruled in favor of the Central States Plan, and that
 decision was appealed by the PLCA. In July 2014, the Central States
 Plan provided Quanta with a Notice and Demand claiming partial
 withdrawal liability in the amount of $39.6 million and requiring
 Quanta to make payments on this assessment while the dispute is
 ongoing. In September 2015, the United States Court of Appeals for
 the Seventh Circuit ruled in favor of the PLCA and reversed the
 district court&amp;#x2019;s previous ruling which had been in favor of
 the Central States Plan. Based on the outcome of the appeal, in
 January 2016, the Central States Plan issued a revised Notice and
 Demand claiming a partial withdrawal liability in the amount of
 $32.9 million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Separately, in December 2013, the Central States
 Plan filed lawsuits against two of Quanta&amp;#x2019;s other
 subsidiaries in connection with their withdrawal in 2012. In the
 first lawsuit, the Central States Plan alleged that the subsidiary
 elected to participate in the Central States Plan pursuant to the
 collective bargaining agreement under which it participated. Quanta
 argued that no such election was made and that any payments made to
 the Central States Plan were made in error. In July 2014, the
 parties reached an agreement to settle the lawsuit, and the court
 dismissed the case with prejudice. In the second lawsuit, the
 Central States Plan alleged that contributions made by the Quanta
 subsidiary to a new industry fund created after Quanta withdrew
 from the Central States Plan should have been made to the Central
 States Plan. This arguably would have extended the withdrawal date
 for this subsidiary to at least the end of 2013. Quanta disputed
 these allegations on the basis that it properly paid contributions
 to the new industry fund based on the terms of the collective
 bargaining agreement under which it participated and asserted that
 it terminated its obligation to contribute to the Central States
 Plan by the end of 2012. The parties both moved for summary
 judgment, and in March 2015, the court entered judgment in favor of
 Quanta. The Central States Plan filed a notice of appeal in April
 2015, and in December 2015, the Central States Plan agreed to
 dismiss the appeal with prejudice.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The ultimate liability associated with the complete
 withdrawal of Quanta&amp;#x2019;s subsidiaries from the Central States
 Plan will depend on various factors, including interpretations of
 the terms of the collective bargaining agreements under which the
 subsidiaries participated and whether exemptions from withdrawal
 liability applicable to construction industry employers will be
 available. In March 2014, the Central States Plan provided revised
 estimates indicating that the total withdrawal liability based on
 certain withdrawal scenarios from 2011 through 2014 could range
 between $40.1 million and $55.4 million, which Quanta believes to
 be the range of reasonably possible loss for this matter.
 Additionally, based on those estimates and allowing for the
 exclusion of amounts believed by management to have been improperly
 included in such estimates, Quanta recorded an adjustment to cost
 of services during the three months ended March&amp;#xA0;31, 2014 to
 increase the recognized withdrawal liability to an amount within
 the range communicated to Quanta by the Central States Plan. Given
 the unknown nature of some of the factors mentioned above, the
 final withdrawal liability cannot yet be determined with certainty.
 Accordingly, it is reasonably possible that the amount owed upon
 final resolution of these matters could be materially higher than
 the expense Quanta had recognized through March&amp;#xA0;31, 2017.
 Although Quanta disputes the total liability owed to the Central
 States Plan, it continues to make monthly payments according to the
 terms of the January 2016 Notice and Demand while the parties
 determine the final withdrawal liability. As of March&amp;#xA0;31,
 2017, Quanta had made payments totaling $19.1 million toward the
 withdrawal liability assessment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;&lt;i&gt;2013 Central States Plan Withdrawal
 Liability.&lt;/i&gt; On October&amp;#xA0;9, 2013, Quanta acquired a company
 that experienced a complete withdrawal from the Central States Plan
 prior to the date of acquisition. Prior to the acquisition, the
 Central States Plan issued a Notice and Demand to the acquired
 company claiming a withdrawal liability in the total amount of $6.9
 million and requiring payments to be made on this assessment while
 the dispute is ongoing. In connection with the acquisition, Quanta
 recorded an initial liability of $4.8 million related to this
 withdrawal liability, and a portion of the purchase price for the
 acquired company was deposited into an escrow account to fund any
 withdrawal obligation in excess of the initial liability recorded.
 In January 2016, the Central States Plan issued a revised Notice
 and Demand claiming a withdrawal liability in the amount of $4.8
 million. Although Quanta continues to dispute the total liability
 owed to the Central States Plan, it continues to make monthly
 payments according to the terms of this revised Notice and Demand
 while the parties determine the final withdrawal liability. As of
 March&amp;#xA0;31, 2017, payments totaling $3.7 million had been made
 toward the withdrawal liability assessment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The final amount of withdrawal liability payable in
 connection with this matter remains the subject of a pending
 arbitration proceeding and will ultimately depend on various
 factors, including the outcome of the PLCA litigation described
 above. However, the acquired company&amp;#x2019;s withdrawal from the
 Central States Plan is not expected to have a material impact on
 Quanta&amp;#x2019;s financial condition, results of operations or cash
 flows.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Indemnities&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta generally indemnifies its customers for the
 services it provides under its contracts, as well as other
 specified liabilities, which may subject Quanta to indemnity claims
 and liabilities and related litigation. Additionally, in connection
 with certain acquisitions and dispositions, Quanta has indemnified
 various parties against specified liabilities that those parties
 might incur in the future. The indemnities under acquisition or
 disposition agreements are usually contingent upon the other party
 incurring liabilities that reach specified thresholds. As of
 March&amp;#xA0;31, 2017, except as otherwise set forth above in
 &lt;i&gt;Legal Proceedings&lt;/i&gt;, Quanta does not believe any material
 liabilities for claims exist against it in connection with any of
 these indemnity obligations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In the normal course of Quanta&amp;#x2019;s acquisition
 transactions, Quanta obtains rights to indemnification from the
 sellers or former owners of acquired companies for certain risks,
 liabilities and obligations arising from their prior operations,
 such as performance, operational, safety, workforce or tax issues,
 some of which Quanta may not have discovered during due diligence.
 However, the indemnities may not cover all of Quanta&amp;#x2019;s
 exposure for such pre-acquisition matters, and the indemnitors may
 be unwilling or unable to pay the amounts owed to Quanta.
 Accordingly, Quanta may incur expenses for which it is not
 reimbursed. Quanta is currently in the process of identifying
 certain pre-acquisition obligations associated with non-U.S.
 payroll taxes that may be due from a business acquired by Quanta in
 2013. As of March&amp;#xA0;31, 2017, Quanta had recorded $11.4 million
 as its best estimate of the pre-acquisition tax obligations and a
 corresponding indemnification asset, as management expects to
 recover from the indemnity counterparties any amounts that Quanta
 may be required to pay in connection with any such obligations.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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. The
 carrying value of variable rate debt also approximates fair value.
 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&amp;#x2019;s cash equivalents were categorized as Level 1 assets
 at March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016, as all values
 were based on unadjusted quoted prices for identical assets in an
 active market that Quanta has the ability to access.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In connection with Quanta&amp;#x2019;s acquisitions,
 identifiable intangible assets acquired typically include goodwill,
 backlog, customer relationships, trade names, covenants
 not-to-compete, patented rights and developed technology. Quanta
 utilizes the fair value premise as the primary basis for its
 valuation procedures, which is a market-based approach to determine
 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, including 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. In accordance with its annual impairment test during the
 quarter ended December&amp;#xA0;31, 2016, the carrying amounts of such
 assets, including goodwill, were compared to their fair values. The
 level of inputs used for these fair value measurements is the
 lowest level (Level 3). Quanta uses the assistance of third party
 specialists to develop valuation assumptions. Quanta believes that
 these valuation methods appropriately represent the methods that
 would be used by other market participants in determining fair
 value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 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 nonrecurring 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 may 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.&lt;/p&gt;

 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
 regarding, among other factors, the customer&amp;#x2019;s access to
 capital, the customer&amp;#x2019;s willingness or ability to pay,
 general economic and market conditions, the ongoing relationship
 with the customer and uncertainties related to the resolution of
 disputed matters. Quanta considers accounts receivable delinquent
 after 30&amp;#xA0;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&amp;#xA0;days. In addition to balances that have been outstanding
 for 90&amp;#xA0;days or more, Quanta also includes accounts receivable
 balances that relate to customers in bankruptcy or with other known
 difficulties in its analysis of the allowance for doubtful
 accounts. Material changes in Quanta&amp;#x2019;s customers&amp;#x2019;
 business or cash flows, which may be impacted by negative economic
 and market conditions, could affect Quanta&amp;#x2019;s ability to
 collect amounts due from them. As of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016, Quanta had allowances for doubtful accounts
 on current receivables of $5.0 million and $2.8 million. Long-term
 accounts receivable are included within other assets.&lt;/p&gt;

 pursuant to retainage provisions in certain contracts are generally
 due upon completion of the contracts and acceptance by the
 customer. Based on Quanta&amp;#x2019;s experience with similar contracts
 in recent years, the majority of the retainage balances at each
 balance sheet date are expected to be collected within the next
 twelve months. Current retainage balances as of March&amp;#xA0;31, 2017
 and December&amp;#xA0;31, 2016 were $253.0 million and $231.0 million
 and were included in accounts receivable. Retainage balances with
 settlement dates beyond the next twelve months were included in
 other assets, net, and as of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016 were $9.4 million and $5.2 million.&lt;/p&gt;

 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 March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016, the balances of
 unbilled receivables included in accounts receivable were $296.7
 million and $206.8 million.&lt;/p&gt;

 requires inventory to be measured at the lower of either cost or
 net realizable value. When evidence exists that the net realizable
 value of inventory is lower than its cost, the difference will be
 recognized as a loss in earnings in the period in which it occurs.
 Quanta adopted this guidance effective January&amp;#xA0;1, 2017, and
 the adoption of the update did not have a significant impact on
 Quanta&amp;#x2019;s consolidated financial statements or related
 disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;In March 2016, the FASB issued an update that
 amends the accounting for share-based payments in several key
 areas, including the treatment and cash flow presentation of tax
 effects related to the settlement of share-based payments and the
 accounting for forfeitures of share-based awards. The new guidance
 requires companies with share-based payments to record all tax
 effects related thereto at settlement (or expiration) through
 income tax expense on the statement of operations rather than
 through additional paid-in capital (APIC) within equity. This
 update also requires excess tax benefits to be classified as an
 operating activity on the statement of cash flows rather than
 reclassified as a financing activity and requires cash paid by an
 employer when withholding shares for taxes to be presented as a
 financing activity. The update also allows companies to either
 account for forfeitures of share-based payments as they occur or to
 estimate forfeitures. This guidance is required to be applied
 prospectively except for the requirement to classify cash paid when
 withholding shares for the employee portion of taxes as a financing
 activity, which requires retrospective application. Quanta adopted
 this guidance effective January&amp;#xA0;1, 2017 and will continue to
 estimate forfeitures of share-based payments. Quanta anticipates
 increased volatility of income tax expense after adoption of this
 guidance, and during the three months ended March&amp;#xA0;31, 2017
 recorded an income tax benefit of $4.9 million related to the
 settlement of share-based awards. APIC was not adjusted for amounts
 recorded prior to 2017, and therefore Quanta&amp;#x2019;s retained
 earnings were not affected by the adoption of this guidance as of
 January&amp;#xA0;1, 2017. Additionally, $6.1 million was reclassified
 from an operating activity to a financing activity on the statement
 of cash flows for the three months ended March&amp;#xA0;31, 2016
 associated with cash paid by Quanta to satisfy tax withholding
 obligations for share-settled awards.&lt;/p&gt;

 amends the consolidation guidance related to how a reporting entity
 that is the single decision maker of a VIE should treat indirect
 interests in the VIE held through related parties that are under
 common control with the reporting entity when determining whether
 it is the primary beneficiary of a VIE. A reporting entity has an
 indirect interest in a VIE if it has a direct interest in a related
 party that, in turn, has a direct interest in the VIE. Quanta
 adopted this guidance on January&amp;#xA0;1, 2017, and the adoption of
 the update did not have a significant impact on its consolidated
 financial statements or related disclosures.&lt;/p&gt;

 change the way companies measure credit losses for most financial
 assets and certain other instruments that are not measured at fair
 value through net income. The update will require companies to use
 an &amp;#x201C;expected loss&amp;#x201D; model for instruments measured at
 amortized cost and to record allowances for available-for-sale
 (AFS) debt securities rather than reduce the carrying amounts. The
 update will also require disclosure of information regarding how a
 company developed its allowance, including changes in the factors
 that influenced management&amp;#x2019;s estimate of expected credit
 losses and the reasons for those changes. Companies will apply this
 standard&amp;#x2019;s provisions as a cumulative-effect adjustment to
 retained earnings as of the beginning of the first reporting period

 to standardize the classification of certain transactions on the
 statement of cash flows. These transactions include contingent
 consideration payments made after a business combination, proceeds
 from the settlement of corporate-owned life insurance policies and
 distributions received from equity method investments. The new
 standard is effective for interim and annual reporting periods

 will require a reporting entity to recognize the tax expense from
 the sale of an asset in the seller&amp;#x2019;s tax jurisdiction when
 the transfer occurs, even though the pre-tax effects of that
 transaction are eliminated in consolidation. Any deferred tax asset
 that arises in the buyer&amp;#x2019;s jurisdiction would also be
 recognized at the time of the transfer. The new guidance will not
 apply to intra-entity transfers of inventory. The income tax
 consequences from the sale of inventory from one member of a
 consolidated entity to another will continue to be deferred until
 the inventory is sold to a third party. The new standard is
 effective for interim and annual reporting periods beginning after
 December&amp;#xA0;15, 2017, although early adoption is permitted. The
 modified retrospective method will be required for transition to
 the new guidance, with a cumulative-effect adjustment recorded in
 retained earnings as of the beginning of the period of adoption.

 to clarify the definition of a business to assist entities with
 evaluation of whether transactions should be accounted for as
 acquisitions or disposals of assets or businesses. The new
 definition requires that when substantially all of the fair value
 of the gross assets acquired or disposed of is concentrated in a
 single identifiable asset or group of similar identifiable assets,
 the asset or group is not a business. The update will require that
 to be considered a business, a set of assets and activities must
 include, at a minimum, an input and a substantive process that
 together significantly contribute to the ability to create output.
 Additionally, the update will remove the evaluation of whether a
 market participant could replace missing elements in order to
 consider the set of assets and activities a business, will provide
 more stringent criteria for sets without outputs and will narrow
 the definition of output. The new standard is effective for interim
 and annual reporting periods beginning after December&amp;#xA0;15,
 2017, although early adoption is permitted for certain
 transactions. The prospective transition method will be required
 for this new guidance. Quanta is currently evaluating the potential

 intended to simplify the subsequent measurement of goodwill by
 eliminating the second step in the current two-step goodwill
 impairment test. The update will require an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity will
 recognize an impairment charge for the amount by which the carrying
 amount exceeds the reporting unit&amp;#x2019;s fair value, if
 applicable. Additionally, the update will eliminate the requirement
 that a reporting unit with a zero or negative carrying amount
 perform a qualitative assessment and the second step of the
 two-step goodwill impairment test and will instead require
 disclosure of the amount of goodwill allocated to each reporting
 unit with a zero or negative carrying amount of net assets. This
 update is effective for public entities for interim and annual
 reporting periods beginning after December&amp;#xA0;15, 2019, although
 early adoption is permitted for interim and annual goodwill
 impairment tests performed on testing dates after January&amp;#xA0;1,
 2017. The prospective transition method will be required for this
 new guidance. Quanta is currently evaluating the potential impact
 of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&amp;#xA0;1,
 2020.&lt;/p&gt;

 requires inventory to be measured at the lower of either cost or
 net realizable value. When evidence exists that the net realizable
 value of inventory is lower than its cost, the difference will be
 recognized as a loss in earnings in the period in which it occurs.
 Quanta adopted this guidance effective January&amp;#xA0;1, 2017, and
 the adoption of the update did not have a significant impact on
 Quanta&amp;#x2019;s consolidated financial statements or related
 disclosures.&lt;/p&gt;

 amends the accounting for share-based payments in several key
 areas, including the treatment and cash flow presentation of tax
 effects related to the settlement of share-based payments and the
 accounting for forfeitures of share-based awards. The new guidance
 requires companies with share-based payments to record all tax
 effects related thereto at settlement (or expiration) through
 income tax expense on the statement of operations rather than
 through additional paid-in capital (APIC) within equity. This
 update also requires excess tax benefits to be classified as an
 operating activity on the statement of cash flows rather than
 reclassified as a financing activity and requires cash paid by an
 employer when withholding shares for taxes to be presented as a
 financing activity. The update also allows companies to either
 account for forfeitures of share-based payments as they occur or to
 estimate forfeitures. This guidance is required to be applied
 prospectively except for the requirement to classify cash paid when
 withholding shares for the employee portion of taxes as a financing
 activity, which requires retrospective application. Quanta adopted
 this guidance effective January&amp;#xA0;1, 2017 and will continue to
 estimate forfeitures of share-based payments. Quanta anticipates
 increased volatility of income tax expense after adoption of this
 guidance, and during the three months ended March&amp;#xA0;31, 2017
 recorded an income tax benefit of $4.9 million related to the
 settlement of share-based awards. APIC was not adjusted for amounts
 recorded prior to 2017, and therefore Quanta&amp;#x2019;s retained
 earnings were not affected by the adoption of this guidance as of
 January&amp;#xA0;1, 2017. Additionally, $6.1 million was reclassified
 from an operating activity to a financing activity on the statement
 of cash flows for the three months ended March&amp;#xA0;31, 2016
 associated with cash paid by Quanta to satisfy tax withholding
 obligations for share-settled awards.&lt;/p&gt;

 amends the consolidation guidance related to how a reporting entity
 that is the single decision maker of a VIE should treat indirect
 interests in the VIE held through related parties that are under
 common control with the reporting entity when determining whether
 it is the primary beneficiary of a VIE. A reporting entity has an
 indirect interest in a VIE if it has a direct interest in a related
 party that, in turn, has a direct interest in the VIE. Quanta
 adopted this guidance on January&amp;#xA0;1, 2017, and the adoption of
 the update did not have a significant impact on its consolidated
 financial statements or related disclosures.&lt;/p&gt;

 an &amp;#x201C;expected loss&amp;#x201D; model for instruments measured at
 amortized cost and to record allowances for available-for-sale
 (AFS) debt securities rather than reduce the carrying amounts. The
 update will also require disclosure of information regarding how a
 company developed its allowance, including changes in the factors
 that influenced management&amp;#x2019;s estimate of expected credit
 losses and the reasons for those changes. Companies will apply this
 standard&amp;#x2019;s provisions as a cumulative-effect adjustment to
 retained earnings as of the beginning of the first reporting period
 in which the guidance is effective. The new standard is effective
 for interim and annual reporting periods beginning after
 December&amp;#xA0;15, 2019, although early adoption is permitted for
 annual reporting periods beginning after December&amp;#xA0;15, 2018.
 Quanta is currently evaluating the potential impact of this
 authoritative guidance on its consolidated financial statements and
 will adopt this guidance by January&amp;#xA0;1, 2020.&lt;/p&gt;

 from the settlement of corporate-owned life insurance policies and
 distributions received from equity method investments. The new

 will require a reporting entity to recognize the tax expense from
 the sale of an asset in the seller&amp;#x2019;s tax jurisdiction when
 the transfer occurs, even though the pre-tax effects of that
 transaction are eliminated in consolidation. Any deferred tax asset
 that arises in the buyer&amp;#x2019;s jurisdiction would also be
 recognized at the time of the transfer. The new guidance will not
 apply to intra-entity transfers of inventory. The income tax
 consequences from the sale of inventory from one member of a
 consolidated entity to another will continue to be deferred until
 the inventory is sold to a third party. The new standard is
 effective for interim and annual reporting periods beginning after
 December&amp;#xA0;15, 2017, although early adoption is permitted. The
 modified retrospective method will be required for transition to
 the new guidance, with a cumulative-effect adjustment recorded in
 retained earnings as of the beginning of the period of adoption.

 to clarify the definition of a business to assist entities with
 evaluation of whether transactions should be accounted for as
 acquisitions or disposals of assets or businesses. The new
 definition requires that when substantially all of the fair value
 of the gross assets acquired or disposed of is concentrated in a
 single identifiable asset or group of similar identifiable assets,
 the asset or group is not a business. The update will require that
 to be considered a business, a set of assets and activities must
 include, at a minimum, an input and a substantive process that
 together significantly contribute to the ability to create output.
 Additionally, the update will remove the evaluation of whether a
 market participant could replace missing elements in order to
 consider the set of assets and activities a business, will provide
 more stringent criteria for sets without outputs and will narrow
 the definition of output. The new standard is effective for interim
 and annual reporting periods beginning after December&amp;#xA0;15,
 2017, although early adoption is permitted for certain
 transactions. The prospective transition method will be required
 for this new guidance. Quanta is currently evaluating the potential
 impact of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&amp;#xA0;1,
 2018.&lt;/p&gt;

 intended to simplify the subsequent measurement of goodwill by
 eliminating the second step in the current two-step goodwill
 impairment test. The update will require an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity will
 recognize an impairment charge for the amount by which the carrying
 amount exceeds the reporting unit&amp;#x2019;s fair value, if
 applicable. Additionally, the update will eliminate the requirement
 that a reporting unit with a zero or negative carrying amount
 perform a qualitative assessment and the second step of the
 two-step goodwill impairment test and will instead require
 disclosure of the amount of goodwill allocated to each reporting
 unit with a zero or negative carrying amount of net assets. This
 update is effective for public entities for interim and annual
 reporting periods beginning after December&amp;#xA0;15, 2019, although
 early adoption is permitted for interim and annual goodwill
 impairment tests performed on testing dates after January&amp;#xA0;1,
 2017. The prospective transition method will be required for this
 new guidance. Quanta is currently evaluating the potential impact
 of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&amp;#xA0;1,
 2020.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;During 2016, Quanta completed five acquisitions.
 The results of four of the acquired companies are generally
 included in Quanta&amp;#x2019;s Electric Power Infrastructure Services
 segment. These companies included an electrical infrastructure
 services company located in Australia, a utility contracting
 company located in Canada, a full service medium- and high-voltage
 powerline contracting company located in the United States and a
 telecommunications company located in Canada. Quanta also acquired
 a pipeline service contractor located in the United States, the
 results of which are generally included in Quanta&amp;#x2019;s Oil and
 Gas Infrastructure Services segment. As these transactions were
 effective during 2016, the results have been included in
 Quanta&amp;#x2019;s consolidated financial statements beginning on the
 respective dates of acquisition. These acquisitions should enable
 Quanta to further enhance its service offerings in the United
 States, Australia and Canada.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta records reserves for income taxes related to
 certain tax positions in those instances where Quanta considers it
 more likely than not that additional taxes may be due in excess of
 amounts reflected on income tax returns filed. When recording
 reserves for expected tax consequences of uncertain positions,
 Quanta assumes that taxing authorities have full knowledge of the
 position and all relevant facts. Quanta continually reviews
 exposure to additional tax obligations, and as further information
 is known or events occur, changes in tax reserves may be recorded.
 To the extent interest and penalties may be assessed by taxing
 authorities on any underpayment of income tax, such amounts have
 been accrued and included in the provision for income taxes.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As of March&amp;#xA0;31, 2017, the total amount of
 unrecognized tax benefits relating to uncertain tax positions was
 $36.4 million, an increase from December&amp;#xA0;31, 2016 of $1.2
 million. This increase in unrecognized tax benefits resulted
 primarily from tax positions to be taken for 2017. Although the
 Internal Revenue Service completed its examination related to tax
 years 2010, 2011 and 2012 during the year ended December&amp;#xA0;31,
 2016, certain subsidiaries remain under examination by various U.S.
 state, Canadian and other foreign tax authorities for multiple
 periods. Quanta believes it is reasonably possible that within the
 next 12 months unrecognized tax benefits may decrease by up to
 $13.4 million as a result of settlement of these examinations or as
 a result of the expiration of certain statute of limitations
 periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;U.S. federal and state and foreign 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 and comprehensive income.&lt;/p&gt;

 telecommunications company located in Canada. Quanta also acquired
 a pipeline service contractor located in the United States, the
 results of which are generally included in Quanta&amp;#x2019;s Oil and
 Gas Infrastructure Services segment. The aggregate consideration
 for these acquisitions consisted of $75.9&amp;#xA0;million paid or
 payable in cash, subject to certain adjustments, 70,840 shares of
 Quanta common stock valued at $1.5&amp;#xA0;million as of the
 settlement date of the applicable acquisition, and contingent
 consideration payments of up to $39.5 million, which will be paid
 if certain financial targets are achieved. Based on the estimated
 fair value of this contingent consideration, Quanta recorded an
 $18.7 million liability. As these transactions were effective
 during 2016, the results have been included in Quanta&amp;#x2019;s
 consolidated financial statements beginning on the respective dates
 of acquisition. These acquisitions should enable Quanta to further

 assessments of the fair values of the acquired assets and assumed
 liabilities related to businesses acquired subsequent to
 March&amp;#xA0;31, 2016, and further adjustments to the purchase price
 allocations may occur. Quanta expects to complete the purchase
 accounting process as soon as practicable but no later than one
 year from the acquisition dates with possible updates primarily
 related to certain tax estimates. The aggregate purchase
 consideration of these businesses acquired in 2016 subsequent to
 March&amp;#xA0;31, 2016 was preliminarily allocated to acquired assets
 and assumed liabilities, which resulted in a preliminary allocation
 of $17.0&amp;#xA0;million of net tangible assets, $18.4 million of
 goodwill and $3.1 million of other intangible assets.&lt;/p&gt;

 price over the net amount of the fair values assigned to assets

 strategically expanded Quanta&amp;#x2019;s Canadian, Australian and
 domestic electric power, oil and gas service and communications
 offerings, which Quanta believes contributes to the recognition of
 the goodwill. In connection with the 2016 acquisitions, goodwill of
 $24.2 million was recorded for the acquired businesses that were
 included within Quanta&amp;#x2019;s Electric Power Infrastructure
 Services Division and $20.3&amp;#xA0;million was recorded for acquired
 businesses that were included within Quanta&amp;#x2019;s Oil and Gas
 Infrastructure Services Division on the dates of acquisition.
 Goodwill of $2.0&amp;#xA0;million related to the 2016 acquisitions is
 expected to be deductible for income tax purposes.&lt;/p&gt;

 the three months ended March&amp;#xA0;31, 2016 have been prepared by
 adjusting the historical results of Quanta to include the
 historical results of the 2016 acquisitions as if they occurred
 January&amp;#xA0;1, 2015. These pro forma combined historical results
 were also adjusted for the following: a reduction of interest
 expense as a result of the repayment of outstanding indebtedness of
 the acquired businesses, a reduction of interest income as a result
 of the cash consideration paid net of cash received, an increase in
 amortization expense due to the incremental intangible assets
 recorded related to the 2016 acquisitions, an increase or decrease
 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&amp;#x2019;s accounting policies, an increase in the number of
 outstanding shares of Quanta common stock and certain
 reclassifications to conform the acquired companies&amp;#x2019;
 presentation to Quanta&amp;#x2019;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 resulted or may result from the 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.&lt;/p&gt;

 the former owners of the acquired companies received exchangeable
 shares of certain Canadian subsidiaries of Quanta, which may be
 exchanged at the option of the holders for Quanta common stock on a
 one-for-one basis. The holders of exchangeable shares can make an
 exchange only once in any calendar quarter and must exchange a
 minimum of either 50,000 shares or, if less, the total number of
 remaining exchangeable shares registered in the name of the holder
 making the request. Additionally, in connection with two of such
 acquisitions, Quanta issued one share of Quanta Series&amp;#xA0;F
 preferred stock and one share of Quanta Series G preferred stock
 (the Preferred Stock) to voting trusts on behalf of the respective
 holders of the exchangeable shares issued in such acquisitions.
 Each share of the Preferred Stock provides the holders of such
 exchangeable shares voting rights in Quanta common stock equivalent
 to the number of exchangeable shares outstanding at that time.&lt;/p&gt;

 vesting of restricted stock, RSUs and performance units settled in
 common stock are typically satisfied by Quanta making such tax
 payments and withholding the number of vested shares having a value
 on the date of vesting equal to the tax withholding obligation. For
 the settlement of these employee tax liabilities, Quanta withheld
 0.5 million&amp;#xA0;and 0.3&amp;#xA0;million shares of Quanta common stock
 during the three months ended March&amp;#xA0;31, 2017 and 2016, with a
 total market value of $17.1 million and $7.1 million. These shares
 and the related costs to acquire them were accounted for as
 adjustments to the balance of treasury stock.&lt;/p&gt;

 board of directors approved a stock repurchase program that
 authorized Quanta to purchase, from time to time through
 February&amp;#xA0;28, 2017, up to $1.25 billion of its outstanding
 common stock (the 2015 Repurchase Program). Repurchases under the
 2015 Repurchase Program were made in open market and privately
 negotiated transactions, including pursuant to an accelerated share
 repurchase arrangement and an issuer repurchase plan. During 2015,
 Quanta repurchased 19.2&amp;#xA0;million shares of its common stock at
 a cost of $449.9 million in the open market under the 2015

 entered into an accelerated share repurchase arrangement (the ASR)
 to repurchase $750.0 million of its common stock under the 2015
 Repurchase Program. Under the terms of the ASR, Quanta paid $750.0
 million to JPMorgan Chase Bank, National Association, London Branch
 (JPMorgan) and initially received 25.7&amp;#xA0;million shares of its
 common stock. The fair market value of these 25.7&amp;#xA0;million
 shares at the time of delivery was $600.0 million, and the
 repurchased shares and the related cost to acquire them were
 accounted for as an adjustment to the balance of treasury stock
 during the third quarter of 2015, reducing the weighted-average
 number of basic and diluted common shares used to calculate
 Quanta&amp;#x2019;s earnings per share. The $150.0 million remaining
 under the ASR was recorded as an adjustment to APIC during the
 third quarter of 2015 and was reclassified from APIC to treasury
 stock upon final settlement of the ASR on April&amp;#xA0;12, 2016. At
 final settlement and based on the final volume-weighted average
 share price during the term of the ASR, minus a discount and
 subject to other adjustments pursuant to the terms and conditions
 of the ASR, Quanta received 9.4&amp;#xA0;million additional shares of
 its common stock from JPMorgan. The 2015 Repurchase Program ended
 on February&amp;#xA0;28, 2017, and Quanta repurchased a total of
 54.3&amp;#xA0;million shares of its common stock at a cost of $1.20
 billion under the 2015 Repurchase Program. No common stock was
 repurchased in the three months ended March&amp;#xA0;31, 2017 or 2016
 under any repurchase programs.&lt;/p&gt;

 infrastructure services to the joint venture, which management
 believes most significantly influences the economic performance of
 the joint venture. Management has concluded that Quanta is the
 primary beneficiary of each of the joint ventures determined to be
 VIEs and has accounted for each on a consolidated basis. The other
 parties&amp;#x2019; equity interests in these joint ventures have been
 accounted for as non-controlling interests in the condensed
 consolidated financial statements. Income attributable to the other
 joint venture members in the amounts of $0.2 million and $0.4
 million for the three months ended March&amp;#xA0;31, 2017 and 2016 has
 been accounted for as a reduction of net income in deriving net
 income attributable to common stock. Equity in the consolidated
 assets and liabilities of these joint ventures that is attributable
 to the other joint venture members has been accounted for as
 non-controlling interests within total equity in the accompanying
 balance sheets.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta presents its operations under two reportable
 segments: (1)&amp;#xA0;Electric Power Infrastructure Services and
 (2)&amp;#xA0;Oil and Gas Infrastructure Services. This structure is
 generally based on the broad end-user markets for Quanta&amp;#x2019;s
 services. See Note&amp;#xA0;1 for additional information regarding
 Quanta&amp;#x2019;s reportable segments.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta&amp;#x2019;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&amp;#x2019;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&amp;#x2019;s operating units
 are organized into one of two internal divisions, namely, the
 Electric Power Infrastructure Services Division and the Oil and Gas
 Infrastructure Services Division. These internal divisions are
 closely aligned with the reportable segments described above based
 on their operating units&amp;#x2019; predominant type of work.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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&amp;#x2019;s market strategies. These classifications
 of Quanta&amp;#x2019;s operating unit revenues by type of work for
 segment reporting purposes can at times require judgment on the
 part of management. Quanta&amp;#x2019;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 service across industries. For
 example, Quanta performs joint trenching projects to install
 distribution lines for electric power and natural gas
 customers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In addition, Quanta&amp;#x2019;s integrated operations
 and common administrative support at each of its operating units
 require that certain allocations of shared and indirect costs, such
 as facility costs and indirect operating expenses, including
 depreciation and general and administrative costs, be 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
 intangible assets are not allocated.&lt;/p&gt;

 million per occurrence. Quanta is generally self-insured for all
 claims that do not exceed the amount of the applicable deductible.
 Quanta also has employee health care benefit plans for most
 employees not subject to collective bargaining agreements, of which
 the primary plan is subject to a deductible of $0.4 million per
 claimant per year.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Losses under all of these insurance programs are
 accrued based upon Quanta&amp;#x2019;s estimate of the ultimate
 liability for claims reported and an estimate of claims incurred
 but not reported, with assistance from third-party actuaries. These
 insurance liabilities are difficult to assess and estimate due to
 unknown factors, including the severity of an injury, the extent of
 damage, the determination of Quanta&amp;#x2019;s liability in proportion
 to other parties and the number of incidents not reported. The
 accruals are based upon known facts and historical trends, and
 management believes such accruals are adequate.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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&amp;#x2019;s investments in joint ventures, which are
 either consolidated or proportionately consolidated, as discussed
 in the following summary of significant accounting policies.
 Investments in affiliated entities in which Quanta does not have a
 controlling financial interest, but over which Quanta has
 significant influence, usually because Quanta holds a voting
 interest of between 20% and 50%, are accounted for using the equity
 method. All significant intercompany accounts and transactions have
 been eliminated in consolidation. Unless the context requires
 otherwise, references to Quanta include Quanta Services, Inc. and
 its consolidated subsidiaries.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Interim Condensed Consolidated Financial
 Information&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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 (US GAAP), 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, comprehensive income and cash flows with respect to the
 interim condensed consolidated financial statements have been
 included. The results of operations and comprehensive income 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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&amp;#x2019;s Annual
 Report on Form&amp;#xA0;10-K for the year ended December&amp;#xA0;31, 2016,
 which was filed with the SEC on March&amp;#xA0;1, 2017.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Reclassifications&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta reclassified certain prior period amounts
 related to stock-based compensation on the statement of cash flows
 to conform to the current period presentation under a recently
 adopted accounting update.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Use of Estimates and Assumptions&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;The preparation of financial statements in
 conformity with US&amp;#xA0;GAAP 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 amounts 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&amp;#x2019;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&amp;#x2019;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, equity and other investments, loan receivables,
 purchase price allocations, liabilities for self-insured and other
 claims and guarantees, multiemployer pension plan withdrawal
 liabilities, revenue recognition for construction contracts
 inclusive of contractual change orders and claims, share-based
 compensation, operating results of reportable segments, as well as
 the provision for income taxes and the calculation of uncertain tax
 positions.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Cash and Cash Equivalents&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta had cash and cash equivalents of $106.5
 million and $112.2 million as of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016. Cash consisting of interest-bearing demand
 deposits is carried at cost, which approximates fair value. Quanta
 considers all highly liquid investments with an original maturity
 of three months or less at the time of purchase to be cash
 equivalents, which are carried at fair value. At March&amp;#xA0;31,
 2017 and December&amp;#xA0;31, 2016, cash equivalents were $8.1 million
 and $8.8 million, and consisted primarily of money market
 investments and money market mutual funds and are discussed further
 in &lt;i&gt;Fair Value Measurements&lt;/i&gt; below. As of March&amp;#xA0;31, 2017
 and December&amp;#xA0;31, 2016, cash and cash equivalents held in
 domestic bank accounts were $17.5 million and $19.5 million, and
 cash and cash equivalents held in foreign bank accounts were $89.0
 million and $92.7 million. As of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016, cash and cash equivalents held by
 Quanta&amp;#x2019;s investments in joint ventures, which are either
 consolidated or proportionately consolidated, were $8.8 million and
 $11.5 million, of which $7.7 million and $10.0 million related to
 domestic joint ventures. Cash and cash equivalents held by the
 joint ventures are available to support the operations of the
 related joint ventures, but Quanta does not have access to that
 cash and cash equivalents for its other operations. Under the terms
 of the partnership agreements, Quanta generally has no right to the
 joint ventures&amp;#x2019; cash and cash equivalents other than
 participating in distributions and in the event of dissolution.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Current and Long-Term Accounts and Notes Receivable and
 Allowance for Doubtful Accounts&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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
 regarding, among other factors, the customer&amp;#x2019;s access to
 capital, the customer&amp;#x2019;s willingness or ability to pay,
 general economic and market conditions, the ongoing relationship
 with the customer and uncertainties related to the resolution of
 disputed matters. Quanta considers accounts receivable delinquent
 after 30&amp;#xA0;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&amp;#xA0;days. In addition to balances that have been outstanding
 for 90&amp;#xA0;days or more, Quanta also includes accounts receivable
 balances that relate to customers in bankruptcy or with other known
 difficulties in its analysis of the allowance for doubtful
 accounts. Material changes in Quanta&amp;#x2019;s customers&amp;#x2019;
 business or cash flows, which may be impacted by negative economic
 and market conditions, could affect Quanta&amp;#x2019;s ability to
 collect amounts due from them. As of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016, Quanta had allowances for doubtful accounts
 on current receivables of $5.0 million and $2.8 million. Long-term
 accounts receivable are included within other assets.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 12pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%" align="justify"&gt;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. Based on Quanta&amp;#x2019;s experience with similar contracts
 in recent years, the majority of the retainage balances at each
 balance sheet date are expected to be collected within the next
 twelve months. Current retainage balances as of March&amp;#xA0;31, 2017
 and December&amp;#xA0;31, 2016 were $253.0 million and $231.0 million
 and were included in accounts receivable. Retainage balances with
 settlement dates beyond the next twelve months were included in
 other assets, net, and as of March&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016 were $9.4 million and $5.2 million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016, the balances of
 unbilled receivables included in accounts receivable were $296.7
 million and $206.8 million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Goodwill and Other Intangibles&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta has recorded goodwill in connection with its
 historical acquisitions of companies. Upon acquisition, these
 companies were either combined into one of Quanta&amp;#x2019;s existing
 operating units or managed on a stand-alone basis as an individual
 operating unit. Goodwill recorded in connection with these
 acquisitions is subject to an annual assessment for impairment,
 which Quanta performs at the operating unit level for each
 operating unit that carries a balance of goodwill. Each of
 Quanta&amp;#x2019;s operating units is organized into one of two
 internal divisions: the Electric Power Infrastructure Services
 Division and the Oil and Gas Infrastructure Services Division. As
 most of the companies acquired by Quanta provide multiple types of
 services for multiple types of customers, these divisional
 designations are based on the predominant type of work performed by
 each operating unit at the point in time the divisional designation
 is made. Goodwill is required to be measured for impairment at the
 reporting unit level, which represents the operating segment level
 or one level below the operating segment level for which discrete
 financial information is available. Quanta has determined that its
 individual operating units represent its reporting units for the
 purpose of assessing goodwill impairments.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta has the option to first assess qualitative
 factors to determine whether it is necessary to perform the
 two-step fair value-based impairment test described below. If
 Quanta 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. Quanta can
 choose to perform the qualitative assessment on none, some or all
 of its reporting units. Quanta 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 the
 qualitative assessment in any subsequent period. Qualitative
 indicators including deterioration in macroeconomic conditions,
 declining financial performance, or a sustained decrease in share
 price, among other things, may trigger the need for annual or
 interim impairment testing of goodwill associated with one or all
 of the reporting units.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta&amp;#x2019;s goodwill impairment assessment is
 performed at year-end, or more frequently if events or
 circumstances arise which indicate that goodwill may be impaired.
 For instance, a decrease in Quanta&amp;#x2019;s market capitalization
 below book value, a significant change in business climate or loss
 of a significant customer, as well as the qualitative indicators
 referenced above, may trigger the need for interim impairment
 testing of goodwill for 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&amp;#x2019;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&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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&amp;#x2019;s opinion, this method currently results in the
 most accurate calculation of a reporting unit&amp;#x2019;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, among others, revenue growth
 rates, operating margins, discount rates, weighted average costs of
 capital and future market conditions. 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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
 one-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&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;For recently acquired reporting units, a step one
 impairment test may indicate an implied fair value that is
 substantially similar to the reporting unit&amp;#x2019;s carrying value.
 Such similarities in value are generally an indication that
 management&amp;#x2019;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;During the fourth quarter of 2016, a two-step
 fair-value based goodwill impairment analysis was performed for
 each of Quanta&amp;#x2019;s reporting units, and no reporting units were
 evaluated solely on a qualitative basis. Step one of the analysis
 indicated that the implied fair value of each of Quanta&amp;#x2019;s
 reporting units, other than recently acquired reporting units and
 the reporting units that recorded goodwill impairment charges in
 2015, was substantially in excess of its carrying value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As discussed generally above, when evaluating the
 2016 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&amp;#x2019;s reporting units were operating.
 Additionally, management considered the sensitivity of its fair
 value estimates to changes in certain valuation assumptions. After
 taking into account a 10% decrease in the fair value of each of
 Quanta&amp;#x2019;s reporting units, two reporting units within
 Quanta&amp;#x2019;s Oil and Gas Infrastructure Division had fair values
 below their respective carrying values. Quanta recorded asset
 impairment charges for these reporting units in 2015. The fair
 values determined in 2016 for these reporting units were consistent
 with the fair values determined in 2015, accordingly the fair
 values approximate the current carrying values. Circumstances such
 as market declines, unfavorable economic conditions, the loss of a
 major customer or other factors could increase the risk of
 impairment of goodwill in future periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;If an operating unit experiences prolonged periods
 of declining revenues, operating margins or both, it may be at risk
 of failing step one of the goodwill impairment test. Certain
 operating units have experienced declines over the short-term due
 to challenging macroeconomic conditions in certain geographic areas
 and low oil and natural gas prices, which have negatively impacted
 customer spending and resulted in project cancellations and delays.
 Additionally, customer capital spending has been constrained as a
 result of an increasingly complex regulatory and permitting
 environment. Certain operating units within Quanta&amp;#x2019;s Oil and
 Gas Infrastructure Services Division that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors. Goodwill and intangible
 assets associated with the operating units within Quanta&amp;#x2019;s
 Oil and Gas Infrastructure Services Division that have been
 significantly impacted by the factors mentioned above were $69.8
 million and $11.7 million at March&amp;#xA0;31, 2017. Quanta monitors
 these conditions and others to determine if it is necessary to
 perform step one of the fair-value based impairment test for one or
 more operating units prior to the annual impairment assessment. No
 interim impairment charges were recorded during the three months
 ended March&amp;#xA0;31, 2017. Although Quanta is not aware of
 circumstances that would lead to a goodwill impairment at a
 reporting unit currently, circumstances such as a continued market
 decline, the loss of a major customer or other factors could impact
 the valuation of goodwill in the future.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta&amp;#x2019;s intangible assets include customer
 relationships, backlog, trade names, non-compete agreements,
 patented rights and developed technology, all subject to
 amortization. The value of customer relationships is estimated as
 of the date a business is acquired based on 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 and estimated customer attrition rates, the
 importance or lack thereof of existing customer relationships to
 Quanta&amp;#x2019;s business plan, income taxes and required rates of
 return. Quanta values backlog for acquired businesses as of the
 acquisition date 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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 business entities, including general or
 limited partnerships, contractual joint ventures, or other forms of
 equity or profit participation. These investments may also include
 Quanta&amp;#x2019;s participation in different financing 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 also
 enters into strategic partnerships with customers and
 infrastructure investors to provide fully integrated infrastructure
 services on certain projects, including planning and feasibility
 analysis, engineering, design, procurement, construction financing
 and investment and project operation and maintenance. These
 projects include public-private partnerships, private
 infrastructure projects and concessions, along with build, own,
 operate and transfer and build to suit arrangements. As part of
 this strategy, Quanta formed a partnership with select
 infrastructure investors that provides $750 million of capital
 available to invest in certain of these infrastructure projects,
 including $60 million from Quanta. Wholly owned subsidiaries of
 Quanta serve as the general partner of this partnership and as a
 separately operating registered investment adviser to manage the
 invested capital.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 have both
 (i)&amp;#xA0;the power to direct the activities of a VIE that most
 significantly affect the VIE&amp;#x2019;s economic performance and
 (ii)&amp;#xA0;the obligation to absorb losses of the VIE or the right
 to receive benefits from the VIE, in either case 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&amp;#x2019;s equity interest in the VIE is accounted for as a
 non-controlling interest. In cases where Quanta determines that it
 has an undivided interest in the assets, liabilities, revenues and
 profits of an unincorporated VIE (e.g., a general partnership
 interest), such amounts are consolidated on a basis proportional to
 Quanta&amp;#x2019;s ownership interest in the unincorporated entity.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Investments 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&amp;#x2019;s share of net income or losses
 from unconsolidated equity investments is included in equity in
 earnings (losses) of unconsolidated affiliates in the consolidated
 statements of operations when applicable. 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 related to investments would be
 recognized in other expense. Equity method investments are carried
 at original cost and are included in other assets, net in the
 consolidated balance sheet and are adjusted for Quanta&amp;#x2019;s
 proportionate share of the investees&amp;#x2019; income, losses and
 distributions.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Through its Electric Power Infrastructure Services
 and Oil and Gas Infrastructure Services segments, Quanta designs,
 installs and maintains networks for customers in the electric
 power, oil and gas and communications 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 these 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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, costs incurred to date compared to
 total estimated contract costs 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 material associated with Quanta&amp;#x2019;s work is
 owner-furnished and is therefore not included in contract revenues
 and costs. The cost estimation process is based on professional
 knowledge and experience of Quanta&amp;#x2019;s engineers, project
 managers and financial professionals. Changes in job performance,
 job conditions and final contract settlements are factors that
 influence management&amp;#x2019;s assessment of total contract value and
 the total estimated costs to complete those contracts and
 therefore, Quanta&amp;#x2019;s profit recognition.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Actual revenues and project costs can vary,
 sometimes substantially, from previous estimates due to changes in
 a variety of factors including unforeseen circumstances not
 included in Quanta&amp;#x2019;s cost estimates or covered by its
 contracts for which it cannot obtain adequate compensation,
 including concealed or unknown environmental conditions; changes in
 the cost of equipment, commodities, materials or labor;
 unanticipated costs or claims due to customer-caused delays,
 customer failure to provide required materials or equipment, errors
 in engineering, specifications or designs, project modifications,
 or contract termination and Quanta&amp;#x2019;s inability to obtain
 reimbursement for such costs or recover on such claims; weather
 conditions; and quality issues requiring rework or replacement.
 These factors, along with other risks inherent in performing fixed
 price contracts may cause actual revenues and gross profits for a
 project to differ from previous estimates and could result in
 reduced profitability or losses on projects. 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. These factors are routinely evaluated on a project by
 project basis throughout the project term, and the impact of
 corresponding revisions in management&amp;#x2019;s estimates of contract
 value, contract cost and contract profit are recorded as necessary
 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Overall, Quanta&amp;#x2019;s operating results for the
 three months ended March&amp;#xA0;31, 2017 were impacted by less than
 5% as a result of aggregate changes in contract estimates related
 to projects that were in progress at December&amp;#xA0;31,
 2016.&amp;#xA0;Included within the operating results for the three
 months ended March&amp;#xA0;31, 2017 were losses from the natural gas
 pipeline project discussed in more detail below, which were largely
 offset by positive changes in estimates resulting from better than
 expected performance on an unrelated natural gas pipeline project.
 Quanta&amp;#x2019;s operating results for the three months ended
 March&amp;#xA0;31, 2016 were impacted by less than 5% as a result of
 aggregate changes in contract estimates related to projects that

 those changes was the impact of a loss on a power plant project in
 Alaska, which is further described below.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As noted above, Quanta experienced weather delays
 on a natural gas transmission project during the three months ended
 March&amp;#xA0;31, 2017, that resulted in an increase of the estimated
 total costs necessary to complete the project. During the three
 months ended March&amp;#xA0;31, 2017, Quanta recognized losses on the
 project of $16.5 million. Quanta is in the process of developing
 potential claims; however, no revenues or cost recovery has been
 reflected in Quanta&amp;#x2019;s estimate of total project losses at
 March&amp;#xA0;31, 2017. At March&amp;#xA0;31, 2017, this project was
 approximately 85% complete. As this project continues, it is
 possible that additional delays or other unforeseen circumstances
 could occur and result in the recognition of additional losses;
 however, such amounts cannot currently be estimated.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;During 2016 and 2015, Quanta experienced
 performance issues on a power plant project in Alaska that resulted
 in an increase of the estimated total costs necessary to complete
 the project. During the three months ended March&amp;#xA0;31, 2016,
 Quanta recognized project losses of $21.3 million. This project was
 substantially completed during the fourth quarter of 2016.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 costs 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As of March&amp;#xA0;31, 2017 and December&amp;#xA0;31,

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta records reserves for income taxes related to
 certain tax positions in those instances where Quanta considers it
 more likely than not that additional taxes may be due in excess of
 amounts reflected on income tax returns filed. When recording
 reserves for expected tax consequences of uncertain positions,
 Quanta assumes that taxing authorities have full knowledge of the
 position and all relevant facts. Quanta continually reviews
 exposure to additional tax obligations, and as further information
 is known or events occur, changes in tax reserves may be recorded.
 To the extent interest and penalties may be assessed by taxing
 authorities on any underpayment of income tax, such amounts have
 been accrued and included in the provision for income taxes.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As of March&amp;#xA0;31, 2017, the total amount of
 unrecognized tax benefits relating to uncertain tax positions was
 $36.4 million, an increase from December&amp;#xA0;31, 2016 of $1.2
 million. This increase in unrecognized tax benefits resulted
 primarily from tax positions to be taken for 2017. Although the
 Internal Revenue Service completed its examination related to tax
 years 2010, 2011 and 2012 during the year ended December&amp;#xA0;31,
 2016, certain subsidiaries remain under examination by various U.S.
 state, Canadian and other foreign tax authorities for multiple
 periods. Quanta believes it is reasonably possible that within the
 next 12 months unrecognized tax benefits may decrease by up to
 $13.4 million as a result of settlement of these examinations or as
 a result of the expiration of certain statute of limitations
 periods.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta is insured for employer&amp;#x2019;s liability,
 workers&amp;#x2019; compensation, auto liability and general liability
 claims. Under these programs, the deductible for employer&amp;#x2019;s
 liability is $1.0 million per occurrence, the deductible for
 workers&amp;#x2019; compensation is $5.0 million per occurrence, and the
 deductibles for auto liability and general liability are $10.0
 million per occurrence. Quanta is generally self-insured for all
 claims that do not exceed the amount of the applicable deductible.
 Quanta also has employee health care benefit plans for most
 employees not subject to collective bargaining agreements, of which
 the primary plan is subject to a deductible of $0.4 million per
 claimant per year.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Losses under all of these insurance programs are
 accrued based upon Quanta&amp;#x2019;s estimate of the ultimate
 liability for claims reported and an estimate of claims incurred
 but not reported, with assistance from third-party actuaries. These
 insurance liabilities are difficult to assess and estimate due to
 unknown factors, including the severity of an injury, the extent of
 damage, the determination of Quanta&amp;#x2019;s liability in proportion
 to other parties and the number of incidents not reported. The
 accruals are based upon known facts and historical trends, and
 management believes such accruals are adequate.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Collective Bargaining Agreements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Some of Quanta&amp;#x2019;s operating units are parties
 to various collective bargaining agreements with unions that
 represent certain of their employees. The collective bargaining
 agreements expire at various times and have typically been
 renegotiated and renewed on terms similar to those in the expiring
 agreements. The agreements require the operating units to pay
 specified wages, provide certain benefits to their union employees
 and contribute certain amounts to multiemployer pension plans and
 employee benefit trusts. Quanta&amp;#x2019;s multiemployer pension plan
 contribution rates generally are specified in the collective
 bargaining agreements (usually on an annual basis), and
 contributions are made to the plans on a
 &amp;#x201C;pay-as-you-go&amp;#x201D; basis based on its union employee
 payrolls. The location and number of union employees that Quanta
 employs at any given time and the plans in which they may
 participate vary depending on the projects Quanta has ongoing at
 that time and the need for union resources in connection with those
 projects. Therefore, Quanta is unable to accurately predict the
 union employee payroll and the amount of the resulting
 multiemployer pension plan contribution obligation for future
 periods.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Stock-Based Compensation&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Quanta recognizes compensation expense for
 restricted stock, restricted stock units (RSUs) and performance
 units to be settled in common stock based on the fair value of the
 awards at the date of grant, net of estimated forfeitures. The fair
 value of restricted stock awards, RSUs and performance units to be
 settled in common stock is determined based on the number of
 shares, RSUs or performance units granted and the closing price of
 Quanta&amp;#x2019;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 recognized as compensation expense.
 The resulting compensation expense from time-based RSU and
 performance unit 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 RSU
 awards is recognized using the graded vesting method over the
 requisite service period. Payments made by Quanta to satisfy
 employees&amp;#x2019; tax withholding obligations associated with awards
 settled in common stock are classified as financing cash flows.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Compensation expense associated with liability
 based awards, such as RSUs that are expected to or may settle in
 cash, is recognized based on a remeasurement of the fair value of
 the award at the end of each reporting period. Upon settlement, the
 holders receive for each RSU an amount in cash equal to the fair
 market value on the settlement date of one share of Quanta common
 stock, as specified in the applicable award agreement. For
 additional information on Quanta&amp;#x2019;s restricted stock, RSU and
 performance unit awards, see Note 9.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Functional Currency and Translation of Financial
 Statements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;The U.S. dollar is the functional currency for the
 majority of Quanta&amp;#x2019;s operations, which are primarily located
 within the United States. The functional currency for
 Quanta&amp;#x2019;s foreign operations, which are primarily located in
 Canada and Australia, is typically the currency of the country in
 which the foreign operating unit is located. Generally, the
 currency in which the operating unit transacts the majority of its
 activities, including billings, financing, payroll and other
 expenditures, would be considered the functional currency. The
 treatment of foreign currency translation gains or losses is
 dependent upon management&amp;#x2019;s determination of the functional
 currency of each 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, comprehensive income and
 cash flows are translated at average monthly rates, while balance
 sheets are translated at month-end exchange rates. The translation
 of the balance sheet results in translation gains or losses, which
 are included as a separate component of equity under the caption
 &amp;#x201C;Accumulated other comprehensive income (loss).&amp;#x201D; Gains
 and losses arising from transactions which are not denominated in
 the operating units&amp;#x2019; functional currencies are included
 within other income (expense) in the statements of operations.&lt;/p&gt;

 changes in Quanta&amp;#x2019;s capital related accounts. Quanta records
 other comprehensive income (loss) for foreign currency translation
 adjustments related to its foreign operations and for other
 revenues, expenses, gains and losses that are included in
 comprehensive income but excluded from net income.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;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. The
 carrying value of variable rate debt also approximates fair value.
 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&amp;#x2019;s cash equivalents were categorized as Level 1 assets
 at March&amp;#xA0;31, 2017 and December&amp;#xA0;31, 2016, as all values
 were based on unadjusted quoted prices for identical assets in an
 active market that Quanta has the ability to access.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In connection with Quanta&amp;#x2019;s acquisitions,
 identifiable intangible assets acquired typically include goodwill,
 backlog, customer relationships, trade names, covenants
 not-to-compete, patented rights and developed technology. Quanta
 utilizes the fair value premise as the primary basis for its
 valuation procedures, which is a market-based approach to determine
 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, including 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. In accordance with its annual impairment test during the
 quarter ended December&amp;#xA0;31, 2016, the carrying amounts of such
 assets, including goodwill, were compared to their fair values. The
 level of inputs used for these fair value measurements is the
 lowest level (Level 3). Quanta uses the assistance of third party
 specialists to develop valuation assumptions. Quanta believes that
 these valuation methods appropriately represent the methods that
 would be used by other market participants in determining fair
 value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 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 nonrecurring 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 may 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.&lt;/p&gt;

 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&amp;#x2019;s operating units
 are organized into one of two internal divisions, namely, the
 Electric Power Infrastructure Services Division and the Oil and Gas
 Infrastructure Services Division. These internal divisions are

 &lt;b&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Through its Electric Power Infrastructure Services
 and Oil and Gas Infrastructure Services segments, Quanta designs,
 installs and maintains networks for customers in the electric
 power, oil and gas and communications 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 these 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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, costs incurred to date compared to
 total estimated contract costs 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 material associated with Quanta&amp;#x2019;s work is
 owner-furnished and is therefore not included in contract revenues
 and costs. The cost estimation process is based on professional
 knowledge and experience of Quanta&amp;#x2019;s engineers, project
 managers and financial professionals. Changes in job performance,
 job conditions and final contract settlements are factors that
 influence management&amp;#x2019;s assessment of total contract value and
 the total estimated costs to complete those contracts and
 therefore, Quanta&amp;#x2019;s profit recognition.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Actual revenues and project costs can vary,
 sometimes substantially, from previous estimates due to changes in
 a variety of factors including unforeseen circumstances not
 included in Quanta&amp;#x2019;s cost estimates or covered by its
 contracts for which it cannot obtain adequate compensation,
 including concealed or unknown environmental conditions; changes in
 the cost of equipment, commodities, materials or labor;
 unanticipated costs or claims due to customer-caused delays,
 customer failure to provide required materials or equipment, errors
 in engineering, specifications or designs, project modifications,
 or contract termination and Quanta&amp;#x2019;s inability to obtain
 reimbursement for such costs or recover on such claims; weather
 conditions; and quality issues requiring rework or replacement.
 These factors, along with other risks inherent in performing fixed
 price contracts may cause actual revenues and gross profits for a
 project to differ from previous estimates and could result in
 reduced profitability or losses on projects. 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. These factors are routinely evaluated on a project by
 project basis throughout the project term, and the impact of
 corresponding revisions in management&amp;#x2019;s estimates of contract
 value, contract cost and contract profit are recorded as necessary
 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Overall, Quanta&amp;#x2019;s operating results for the
 three months ended March&amp;#xA0;31, 2017 were impacted by less than
 5% as a result of aggregate changes in contract estimates related
 to projects that were in progress at December&amp;#xA0;31,
 2016.&amp;#xA0;Included within the operating results for the three
 months ended March&amp;#xA0;31, 2017 were losses from the natural gas
 pipeline project discussed in more detail below, which were largely
 offset by positive changes in estimates resulting from better than
 expected performance on an unrelated natural gas pipeline project.
 Quanta&amp;#x2019;s operating results for the three months ended
 March&amp;#xA0;31, 2016 were impacted by less than 5% as a result of
 aggregate changes in contract estimates related to projects that
 were in progress at December&amp;#xA0;31, 2015; however; included in
 those changes was the impact of a loss on a power plant project in
 Alaska, which is further described below.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As noted above, Quanta experienced weather delays
 on a natural gas transmission project during the three months ended
 March&amp;#xA0;31, 2017, that resulted in an increase of the estimated
 total costs necessary to complete the project. During the three
 months ended March&amp;#xA0;31, 2017, Quanta recognized losses on the
 project of $16.5 million. Quanta is in the process of developing
 potential claims; however, no revenues or cost recovery has been
 reflected in Quanta&amp;#x2019;s estimate of total project losses at
 March&amp;#xA0;31, 2017. At March&amp;#xA0;31, 2017, this project was
 approximately 85% complete. As this project continues, it is
 possible that additional delays or other unforeseen circumstances
 could occur and result in the recognition of additional losses;
 however, such amounts cannot currently be estimated.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;During 2016 and 2015, Quanta experienced
 performance issues on a power plant project in Alaska that resulted
 in an increase of the estimated total costs necessary to complete
 the project. During the three months ended March&amp;#xA0;31, 2016,
 Quanta recognized project losses of $21.3 million. This project was
 substantially completed during the fourth quarter of 2016.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The current asset &amp;#x201C;Costs and estimated
 earnings in excess of billings on uncompleted contracts&amp;#x201D;
 represents revenues recognized in excess of amounts billed for
 fixed price contracts. The current liability &amp;#x201C;Billings in
 excess of costs and estimated earnings on uncompleted
 contracts&amp;#x201D; represents billings in excess of revenues
 recognized for fixed price contracts.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;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 costs 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;As of March&amp;#xA0;31, 2017 and December&amp;#xA0;31,
 2016, Quanta had recognized revenues of $147.1&amp;#xA0;million and
 $137.8 million related to 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;These aggregate contract price adjustments
 represent management&amp;#x2019;s best estimate of additional contract
 revenues which have been earned and which management believes are
 probable of collection. The amounts ultimately realized by Quanta
 upon final acceptance by its customers could be higher or lower
 than such estimated amounts; however, such amounts cannot currently
 be estimated.&lt;/p&gt;

 board of directors approved a stock repurchase program that
 authorized Quanta to purchase, from time to time through
 February&amp;#xA0;28, 2017, up to $1.25 billion of its outstanding
 common stock (the 2015 Repurchase Program). Repurchases under the
 2015 Repurchase Program were made in open market and privately
 negotiated transactions, including pursuant to an accelerated share
 repurchase arrangement and an issuer repurchase plan. During 2015,
 Quanta repurchased 19.2&amp;#xA0;million shares of its common stock at
 a cost of $449.9 million in the open market under the 2015
 Repurchase Program.&lt;/p&gt;

 entered into an accelerated share repurchase arrangement (the ASR)
 to repurchase $750.0 million of its common stock under the 2015
 Repurchase Program. Under the terms of the ASR, Quanta paid $750.0
 million to JPMorgan Chase Bank, National Association, London Branch
 (JPMorgan) and initially received 25.7&amp;#xA0;million shares of its
 common stock. The fair market value of these 25.7&amp;#xA0;million
 shares at the time of delivery was $600.0 million, and the
 repurchased shares and the related cost to acquire them were
 accounted for as an adjustment to the balance of treasury stock
 during the third quarter of 2015, reducing the weighted-average
 number of basic and diluted common shares used to calculate
 Quanta&amp;#x2019;s earnings per share. The $150.0 million remaining
 under the ASR was recorded as an adjustment to APIC during the
 third quarter of 2015 and was reclassified from APIC to treasury
 stock upon final settlement of the ASR on April&amp;#xA0;12, 2016. At
 final settlement and based on the final volume-weighted average
 share price during the term of the ASR, minus a discount and
 subject to other adjustments pursuant to the terms and conditions
 of the ASR, Quanta received 9.4&amp;#xA0;million additional shares of
 its common stock from JPMorgan. The 2015 Repurchase Program ended
 on February&amp;#xA0;28, 2017, and Quanta repurchased a total of
 54.3&amp;#xA0;million shares of its common stock at a cost of $1.20
 billion under the 2015 Repurchase Program. No common stock was
 repurchased in the three months ended March&amp;#xA0;31, 2017 or 2016
 under any repurchase programs.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;Some of Quanta&amp;#x2019;s operating units are parties
 to various collective bargaining agreements with unions that
 represent certain of their employees. The collective bargaining
 agreements expire at various times and have typically been
 renegotiated and renewed on terms similar to those in the expiring
 agreements. The agreements require the operating units to pay
 specified wages, provide certain benefits to their union employees
 and contribute certain amounts to multiemployer pension plans and
 employee benefit trusts. Quanta&amp;#x2019;s multiemployer pension plan
 contribution rates generally are specified in the collective
 bargaining agreements (usually on an annual basis), and
 contributions are made to the plans on a
 &amp;#x201C;pay-as-you-go&amp;#x201D; basis based on its union employee
 payrolls. The location and number of union employees that Quanta
 employs at any given time and the plans in which they may
 participate vary depending on the projects Quanta has ongoing at
 that time and the need for union resources in connection with those
 projects. Therefore, Quanta is unable to accurately predict the
 union employee payroll and the amount of the resulting
 multiemployer pension plan contribution obligation for future
 periods.&lt;/p&gt;

 into various types of investment arrangements, each having unique
 terms and conditions. These investments may include equity
 interests held by Quanta in business entities, including general or
 limited partnerships, contractual joint ventures, or other forms of
 equity or profit participation. These investments may also include
 Quanta&amp;#x2019;s participation in different financing 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 also
 enters into strategic partnerships with customers and
 infrastructure investors to provide fully integrated infrastructure
 services on certain projects, including planning and feasibility
 analysis, engineering, design, procurement, construction financing
 and investment and project operation and maintenance. These
 projects include public-private partnerships, private
 infrastructure projects and concessions, along with build, own,
 operate and transfer and build to suit arrangements. As part of
 this strategy, Quanta formed a partnership with select
 infrastructure investors that provides $750 million of capital
 available to invest in certain of these infrastructure projects,
 including $60 million from Quanta. Wholly owned subsidiaries of
 Quanta serve as the general partner of this partnership and as a
 separately operating registered investment adviser to manage the
 invested capital.&lt;/p&gt;

 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 have both
 (i)&amp;#xA0;the power to direct the activities of a VIE that most
 significantly affect the VIE&amp;#x2019;s economic performance and
 (ii)&amp;#xA0;the obligation to absorb losses of the VIE or the right
 to receive benefits from the VIE, in either case 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&amp;#x2019;s equity interest in the VIE is accounted for as a
 non-controlling interest. In cases where Quanta determines that it
 has an undivided interest in the assets, liabilities, revenues and
 profits of an unincorporated VIE (e.g., a general partnership
 interest), such amounts are consolidated on a basis proportional to
 Quanta&amp;#x2019;s ownership interest in the unincorporated entity.&lt;/p&gt;

 primary beneficiary, but over which Quanta has the ability to
 exercise significant influence, are accounted for using the equity
 method of accounting. Quanta&amp;#x2019;s share of net income or losses
 from unconsolidated equity investments is included in equity in
 earnings (losses) of unconsolidated affiliates in the consolidated
 statements of operations when applicable. 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 related to investments would be
 recognized in other expense. Equity method investments are carried
 at original cost and are included in other assets, net in the
 consolidated balance sheet and are adjusted for Quanta&amp;#x2019;s
 proportionate share of the investees&amp;#x2019; income, losses and
 distributions.&lt;/p&gt;

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">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&#x2019;s investments in joint ventures, which are
 either consolidated or proportionately consolidated, as discussed
 in the following summary of significant accounting policies.
 Investments in affiliated entities in which Quanta does not have a
 controlling financial interest, but over which Quanta has
 significant influence, usually because Quanta holds a voting
 interest of between 20% and 50%, are accounted for using the equity
 method. All significant intercompany accounts and transactions have
 been eliminated in consolidation. Unless the context requires
 otherwise, references to Quanta include Quanta Services, Inc. and
 its consolidated subsidiaries.</p>

 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 (US GAAP), 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, comprehensive income and cash flows with respect to the
 interim condensed consolidated financial statements have been
 included. The results of operations and comprehensive income 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.</p>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">The preparation of financial statements in
 conformity with US&#xA0;GAAP 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 amounts 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&#x2019;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&#x2019;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, equity and other investments, loan receivables,
 purchase price allocations, liabilities for self-insured and other
 claims and guarantees, multiemployer pension plan withdrawal
 liabilities, revenue recognition for construction contracts
 inclusive of contractual change orders and claims, share-based
 compensation, operating results of reportable segments, as well as
 the provision for income taxes and the calculation of uncertain tax
 positions.</p>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">Quanta had cash and cash equivalents of $106.5
 million and $112.2 million as of March&#xA0;31, 2017 and
 December&#xA0;31, 2016. Cash consisting of interest-bearing demand
 deposits is carried at cost, which approximates fair value. Quanta
 considers all highly liquid investments with an original maturity
 of three months or less at the time of purchase to be cash
 equivalents, which are carried at fair value. At March&#xA0;31,
 2017 and December&#xA0;31, 2016, cash equivalents were $8.1 million
 and $8.8 million, and consisted primarily of money market
 investments and money market mutual funds and are discussed further
 in <i>Fair Value Measurements</i> below. As of March&#xA0;31, 2017
 and December&#xA0;31, 2016, cash and cash equivalents held in
 domestic bank accounts were $17.5 million and $19.5 million, and
 cash and cash equivalents held in foreign bank accounts were $89.0
 million and $92.7 million. As of March&#xA0;31, 2017 and
 December&#xA0;31, 2016, cash and cash equivalents held by
 Quanta&#x2019;s investments in joint ventures, which are either
 consolidated or proportionately consolidated, were $8.8 million and
 $11.5 million, of which $7.7 million and $10.0 million related to
 domestic joint ventures. Cash and cash equivalents held by the
 joint ventures are available to support the operations of the
 related joint ventures, but Quanta does not have access to that
 cash and cash equivalents for its other operations. Under the terms
 of the partnership agreements, Quanta generally has no right to the
 joint ventures&#x2019; cash and cash equivalents other than
 participating in distributions and in the event of dissolution.</p>

 <b><i>Current and Long-Term Accounts and Notes Receivable and
 Allowance for Doubtful Accounts</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">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
 regarding, among other factors, the customer&#x2019;s access to
 capital, the customer&#x2019;s willingness or ability to pay,
 general economic and market conditions, the ongoing relationship
 with the customer and uncertainties related to the resolution of
 disputed matters. Quanta considers accounts receivable delinquent
 after 30&#xA0;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&#xA0;days. In addition to balances that have been outstanding
 for 90&#xA0;days or more, Quanta also includes accounts receivable
 balances that relate to customers in bankruptcy or with other known
 difficulties in its analysis of the allowance for doubtful
 accounts. Material changes in Quanta&#x2019;s customers&#x2019;
 business or cash flows, which may be impacted by negative economic
 and market conditions, could affect Quanta&#x2019;s ability to
 collect amounts due from them. As of March&#xA0;31, 2017 and
 December&#xA0;31, 2016, Quanta had allowances for doubtful accounts
 on current receivables of $5.0 million and $2.8 million. Long-term
 accounts receivable are included within other assets.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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.</p>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%" align="justify">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. Based on Quanta&#x2019;s experience with similar contracts
 in recent years, the majority of the retainage balances at each
 balance sheet date are expected to be collected within the next
 twelve months. Current retainage balances as of March&#xA0;31, 2017
 and December&#xA0;31, 2016 were $253.0 million and $231.0 million
 and were included in accounts receivable. Retainage balances with
 settlement dates beyond the next twelve months were included in
 other assets, net, and as of March&#xA0;31, 2017 and
 December&#xA0;31, 2016 were $9.4 million and $5.2 million.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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 March&#xA0;31, 2017 and December&#xA0;31, 2016, the balances of
 unbilled receivables included in accounts receivable were $296.7
 million and $206.8 million.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt">
 <b><i>Goodwill and Other Intangibles</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">Quanta has recorded goodwill in connection with its
 historical acquisitions of companies. Upon acquisition, these
 companies were either combined into one of Quanta&#x2019;s existing
 operating units or managed on a stand-alone basis as an individual
 operating unit. Goodwill recorded in connection with these
 acquisitions is subject to an annual assessment for impairment,
 which Quanta performs at the operating unit level for each
 operating unit that carries a balance of goodwill. Each of
 Quanta&#x2019;s operating units is organized into one of two
 internal divisions: the Electric Power Infrastructure Services
 Division and the Oil and Gas Infrastructure Services Division. As
 most of the companies acquired by Quanta provide multiple types of
 services for multiple types of customers, these divisional
 designations are based on the predominant type of work performed by
 each operating unit at the point in time the divisional designation
 is made. Goodwill is required to be measured for impairment at the
 reporting unit level, which represents the operating segment level
 or one level below the operating segment level for which discrete
 financial information is available. Quanta has determined that its
 individual operating units represent its reporting units for the
 purpose of assessing goodwill impairments.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Quanta has the option to first assess qualitative
 factors to determine whether it is necessary to perform the
 two-step fair value-based impairment test described below. If
 Quanta 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. Quanta can
 choose to perform the qualitative assessment on none, some or all
 of its reporting units. Quanta 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 the
 qualitative assessment in any subsequent period. Qualitative
 indicators including deterioration in macroeconomic conditions,
 declining financial performance, or a sustained decrease in share
 price, among other things, may trigger the need for annual or
 interim impairment testing of goodwill associated with one or all
 of the reporting units.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Quanta&#x2019;s goodwill impairment assessment is
 performed at year-end, or more frequently if events or
 circumstances arise which indicate that goodwill may be impaired.
 For instance, a decrease in Quanta&#x2019;s market capitalization
 below book value, a significant change in business climate or loss
 of a significant customer, as well as the qualitative indicators
 referenced above, may trigger the need for interim impairment
 testing of goodwill for 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&#x2019;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&#x2019;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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&#x2019;s opinion, this method currently results in the
 most accurate calculation of a reporting unit&#x2019;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, among others, revenue growth
 rates, operating margins, discount rates, weighted average costs of
 capital and future market conditions. 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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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
 one-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&#x2019;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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&#x2019;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">For recently acquired reporting units, a step one
 impairment test may indicate an implied fair value that is
 substantially similar to the reporting unit&#x2019;s carrying value.
 Such similarities in value are generally an indication that
 management&#x2019;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">During the fourth quarter of 2016, a two-step
 fair-value based goodwill impairment analysis was performed for
 each of Quanta&#x2019;s reporting units, and no reporting units were
 evaluated solely on a qualitative basis. Step one of the analysis
 indicated that the implied fair value of each of Quanta&#x2019;s
 reporting units, other than recently acquired reporting units and
 the reporting units that recorded goodwill impairment charges in
 2015, was substantially in excess of its carrying value.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">As discussed generally above, when evaluating the
 2016 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&#x2019;s reporting units were operating.
 Additionally, management considered the sensitivity of its fair
 value estimates to changes in certain valuation assumptions. After
 taking into account a 10% decrease in the fair value of each of
 Quanta&#x2019;s reporting units, two reporting units within
 Quanta&#x2019;s Oil and Gas Infrastructure Division had fair values
 below their respective carrying values. Quanta recorded asset
 impairment charges for these reporting units in 2015. The fair
 values determined in 2016 for these reporting units were consistent
 with the fair values determined in 2015, accordingly the fair
 values approximate the current carrying values. Circumstances such
 as market declines, unfavorable economic conditions, the loss of a
 major customer or other factors could increase the risk of
 impairment of goodwill in future periods.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">If an operating unit experiences prolonged periods
 of declining revenues, operating margins or both, it may be at risk
 of failing step one of the goodwill impairment test. Certain
 operating units have experienced declines over the short-term due
 to challenging macroeconomic conditions in certain geographic areas
 and low oil and natural gas prices, which have negatively impacted
 customer spending and resulted in project cancellations and delays.
 Additionally, customer capital spending has been constrained as a
 result of an increasingly complex regulatory and permitting
 environment. Certain operating units within Quanta&#x2019;s Oil and
 Gas Infrastructure Services Division that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors. Goodwill and intangible
 assets associated with the operating units within Quanta&#x2019;s
 Oil and Gas Infrastructure Services Division that have been
 significantly impacted by the factors mentioned above were $69.8
 million and $11.7 million at March&#xA0;31, 2017. Quanta monitors
 these conditions and others to determine if it is necessary to
 perform step one of the fair-value based impairment test for one or
 more operating units prior to the annual impairment assessment. No
 interim impairment charges were recorded during the three months
 ended March&#xA0;31, 2017. Although Quanta is not aware of
 circumstances that would lead to a goodwill impairment at a
 reporting unit currently, circumstances such as a continued market
 decline, the loss of a major customer or other factors could impact
 the valuation of goodwill in the future.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Quanta&#x2019;s intangible assets include customer
 relationships, backlog, trade names, non-compete agreements,
 patented rights and developed technology, all subject to
 amortization. The value of customer relationships is estimated as
 of the date a business is acquired based on 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 and estimated customer attrition rates, the
 importance or lack thereof of existing customer relationships to
 Quanta&#x2019;s business plan, income taxes and required rates of
 return. Quanta values backlog for acquired businesses as of the
 acquisition date 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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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.</p>

 into various types of investment arrangements, each having unique
 terms and conditions. These investments may include equity
 interests held by Quanta in business entities, including general or
 limited partnerships, contractual joint ventures, or other forms of
 equity or profit participation. These investments may also include
 Quanta&#x2019;s participation in different financing 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 also
 enters into strategic partnerships with customers and
 infrastructure investors to provide fully integrated infrastructure
 services on certain projects, including planning and feasibility
 analysis, engineering, design, procurement, construction financing
 and investment and project operation and maintenance. These
 projects include public-private partnerships, private
 infrastructure projects and concessions, along with build, own,
 operate and transfer and build to suit arrangements. As part of
 this strategy, Quanta formed a partnership with select
 infrastructure investors that provides $750 million of capital
 available to invest in certain of these infrastructure projects,
 including $60 million from Quanta. Wholly owned subsidiaries of
 Quanta serve as the general partner of this partnership and as a

 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 have both
 (i)&#xA0;the power to direct the activities of a VIE that most
 significantly affect the VIE&#x2019;s economic performance and
 (ii)&#xA0;the obligation to absorb losses of the VIE or the right
 to receive benefits from the VIE, in either case 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&#x2019;s equity interest in the VIE is accounted for as a
 non-controlling interest. In cases where Quanta determines that it
 has an undivided interest in the assets, liabilities, revenues and
 profits of an unincorporated VIE (e.g., a general partnership
 interest), such amounts are consolidated on a basis proportional to
 Quanta&#x2019;s ownership interest in the unincorporated entity.</p>

 method of accounting. Quanta&#x2019;s share of net income or losses
 from unconsolidated equity investments is included in equity in
 earnings (losses) of unconsolidated affiliates in the consolidated
 statements of operations when applicable. 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 related to investments would be
 recognized in other expense. Equity method investments are carried
 at original cost and are included in other assets, net in the
 consolidated balance sheet and are adjusted for Quanta&#x2019;s

 and Oil and Gas Infrastructure Services segments, Quanta designs,
 installs and maintains networks for customers in the electric
 power, oil and gas and communications 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 these 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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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, costs incurred to date compared to
 total estimated contract costs 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 material associated with Quanta&#x2019;s work is
 owner-furnished and is therefore not included in contract revenues
 and costs. The cost estimation process is based on professional
 knowledge and experience of Quanta&#x2019;s engineers, project
 managers and financial professionals. Changes in job performance,
 job conditions and final contract settlements are factors that
 influence management&#x2019;s assessment of total contract value and
 the total estimated costs to complete those contracts and

 including concealed or unknown environmental conditions; changes in
 the cost of equipment, commodities, materials or labor;
 unanticipated costs or claims due to customer-caused delays,
 customer failure to provide required materials or equipment, errors
 in engineering, specifications or designs, project modifications,
 or contract termination and Quanta&#x2019;s inability to obtain
 reimbursement for such costs or recover on such claims; weather
 conditions; and quality issues requiring rework or replacement.
 These factors, along with other risks inherent in performing fixed
 price contracts may cause actual revenues and gross profits for a
 project to differ from previous estimates and could result in
 reduced profitability or losses on projects. 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. These factors are routinely evaluated on a project by
 project basis throughout the project term, and the impact of
 corresponding revisions in management&#x2019;s estimates of contract
 value, contract cost and contract profit are recorded as necessary

 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

 <b><i>Functional Currency and Translation of Financial
 Statements</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">The U.S. dollar is the functional currency for the
 majority of Quanta&#x2019;s operations, which are primarily located
 within the United States. The functional currency for
 Quanta&#x2019;s foreign operations, which are primarily located in
 Canada and Australia, is typically the currency of the country in
 which the foreign operating unit is located. Generally, the
 currency in which the operating unit transacts the majority of its
 activities, including billings, financing, payroll and other
 expenditures, would be considered the functional currency. The
 treatment of foreign currency translation gains or losses is
 dependent upon management&#x2019;s determination of the functional
 currency of each 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, comprehensive income and
 cash flows are translated at average monthly rates, while balance
 sheets are translated at month-end exchange rates. The translation
 of the balance sheet results in translation gains or losses, which
 are included as a separate component of equity under the caption
 &#x201C;Accumulated other comprehensive income (loss).&#x201D; Gains
 and losses arising from transactions which are not denominated in
 the operating units&#x2019; functional currencies are included
 within other income (expense) in the statements of operations.</p>

 <b><i>Fair Value Measurements</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">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. The
 carrying value of variable rate debt also approximates fair value.
 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&#x2019;s cash equivalents were categorized as Level 1 assets
 at March&#xA0;31, 2017 and December&#xA0;31, 2016, as all values
 were based on unadjusted quoted prices for identical assets in an
 active market that Quanta has the ability to access.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">In connection with Quanta&#x2019;s acquisitions,
 identifiable intangible assets acquired typically include goodwill,
 backlog, customer relationships, trade names, covenants
 not-to-compete, patented rights and developed technology. Quanta
 utilizes the fair value premise as the primary basis for its
 valuation procedures, which is a market-based approach to determine
 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, including 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. In accordance with its annual impairment test during the
 quarter ended December&#xA0;31, 2016, the carrying amounts of such
 assets, including goodwill, were compared to their fair values. The
 level of inputs used for these fair value measurements is the
 lowest level (Level 3). Quanta uses the assistance of third party
 specialists to develop valuation assumptions. Quanta believes that
 these valuation methods appropriately represent the methods that
 would be used by other market participants in determining fair
 value.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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 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 nonrecurring 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 may 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.</p>

 requires inventory to be measured at the lower of either cost or
 net realizable value. When evidence exists that the net realizable
 value of inventory is lower than its cost, the difference will be
 recognized as a loss in earnings in the period in which it occurs.
 Quanta adopted this guidance effective January&#xA0;1, 2017, and
 the adoption of the update did not have a significant impact on
 Quanta&#x2019;s consolidated financial statements or related
 disclosures.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &quot;Times New Roman&quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify">In March 2016, the FASB issued an update that
 amends the accounting for share-based payments in several key
 areas, including the treatment and cash flow presentation of tax
 effects related to the settlement of share-based payments and the
 accounting for forfeitures of share-based awards. The new guidance
 requires companies with share-based payments to record all tax
 effects related thereto at settlement (or expiration) through
 income tax expense on the statement of operations rather than
 through additional paid-in capital (APIC) within equity. This
 update also requires excess tax benefits to be classified as an
 operating activity on the statement of cash flows rather than
 reclassified as a financing activity and requires cash paid by an
 employer when withholding shares for taxes to be presented as a
 financing activity. The update also allows companies to either
 account for forfeitures of share-based payments as they occur or to
 estimate forfeitures. This guidance is required to be applied
 prospectively except for the requirement to classify cash paid when
 withholding shares for the employee portion of taxes as a financing
 activity, which requires retrospective application. Quanta adopted
 this guidance effective January&#xA0;1, 2017 and will continue to
 estimate forfeitures of share-based payments. Quanta anticipates
 increased volatility of income tax expense after adoption of this
 guidance, and during the three months ended March&#xA0;31, 2017
 recorded an income tax benefit of $4.9 million related to the
 settlement of share-based awards. APIC was not adjusted for amounts
 recorded prior to 2017, and therefore Quanta&#x2019;s retained
 earnings were not affected by the adoption of this guidance as of
 January&#xA0;1, 2017. Additionally, $6.1 million was reclassified
 from an operating activity to a financing activity on the statement
 of cash flows for the three months ended March&#xA0;31, 2016
 associated with cash paid by Quanta to satisfy tax withholding
 obligations for share-settled awards.</p>

 amends the consolidation guidance related to how a reporting entity
 that is the single decision maker of a VIE should treat indirect
 interests in the VIE held through related parties that are under
 common control with the reporting entity when determining whether
 it is the primary beneficiary of a VIE. A reporting entity has an
 indirect interest in a VIE if it has a direct interest in a related
 party that, in turn, has a direct interest in the VIE. Quanta
 adopted this guidance on January&#xA0;1, 2017, and the adoption of
 the update did not have a significant impact on its consolidated
 financial statements or related disclosures.</p>

 supersedes most current revenue recognition guidance, as well as
 some cost recognition guidance. The update requires that the
 recognition of revenue related to the transfer of goods or services
 to customers reflects the consideration to which the entity expects
 to be entitled in exchange for those goods or services. This update
 also requires new qualitative and quantitative disclosures about
 the nature, amount, timing and uncertainty of revenues and cash
 flows arising from customer contracts, including significant
 judgments and changes in judgments, information about contract
 balances and performance obligations, and assets recognized from
 costs incurred to obtain or fulfill a contract. In July 2015, the
 FASB affirmed its proposal to defer the effective date until fiscal
 years beginning on or after December&#xA0;15, 2017. The guidance
 can be applied on a full retrospective or modified retrospective
 basis whereby the entity records a cumulative effect of initially
 applying this update at the date of initial application.</p>

 of this update on its consolidated financial statements. Quanta
 currently anticipates adopting the update using the modified
 retrospective transition method, which may result in a
 cumulative-effect adjustment recorded in retained earnings as of
 the beginning of the period of adoption. In addition, Quanta
 continues to monitor activity related to the new standard as well
 as working with various non-authoritative groups regarding industry
 clarifications and interpretations, which may impact Quanta&#x2019;s
 considerations and conclusions. While Quanta is still evaluating
 the requirements of this update, it currently does not expect the
 update to materially affect its results of operations, financial
 position or cash flows. This preliminary conclusion is based on
 Quanta&#x2019;s belief that it will generally continue to recognize
 revenues from long-term service contracts over time as services are
 performed and the underlying obligation to the customer is
 fulfilled. Quanta has identified and is in the process of
 implementing changes to its processes and internal controls to meet
 the reporting and disclosure requirements of this update and will
 adopt this update effective January&#xA0;1, 2018.</p>

 change the way companies measure credit losses for most financial
 assets and certain other instruments that are not measured at fair
 value through net income. The update will require companies to use
 an &#x201C;expected loss&#x201D; model for instruments measured at
 amortized cost and to record allowances for available-for-sale
 (AFS) debt securities rather than reduce the carrying amounts. The
 update will also require disclosure of information regarding how a
 company developed its allowance, including changes in the factors
 that influenced management&#x2019;s estimate of expected credit
 losses and the reasons for those changes. Companies will apply this
 standard&#x2019;s provisions as a cumulative-effect adjustment to
 retained earnings as of the beginning of the first reporting period
 in which the guidance is effective. The new standard is effective
 for interim and annual reporting periods beginning after
 December&#xA0;15, 2019, although early adoption is permitted for
 annual reporting periods beginning after December&#xA0;15, 2018.
 Quanta is currently evaluating the potential impact of this

 to standardize the classification of certain transactions on the
 statement of cash flows. These transactions include contingent
 consideration payments made after a business combination, proceeds
 from the settlement of corporate-owned life insurance policies and
 distributions received from equity method investments. The new
 standard is effective for interim and annual reporting periods
 beginning after December&#xA0;15, 2017, although early adoption is
 permitted, and requires application using a retrospective
 transition method. Quanta is currently evaluating the potential
 impact of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&#xA0;1,
 2018.</p>

 will require a reporting entity to recognize the tax expense from
 the sale of an asset in the seller&#x2019;s tax jurisdiction when
 the transfer occurs, even though the pre-tax effects of that
 transaction are eliminated in consolidation. Any deferred tax asset
 that arises in the buyer&#x2019;s jurisdiction would also be
 recognized at the time of the transfer. The new guidance will not
 apply to intra-entity transfers of inventory. The income tax
 consequences from the sale of inventory from one member of a
 consolidated entity to another will continue to be deferred until
 the inventory is sold to a third party. The new standard is
 effective for interim and annual reporting periods beginning after
 December&#xA0;15, 2017, although early adoption is permitted. The
 modified retrospective method will be required for transition to
 the new guidance, with a cumulative-effect adjustment recorded in
 retained earnings as of the beginning of the period of adoption.
 Quanta is currently evaluating the potential impact of this
 authoritative guidance on its consolidated financial statements and
 will adopt this guidance by January&#xA0;1, 2018.</p>

 to clarify the definition of a business to assist entities with
 evaluation of whether transactions should be accounted for as
 acquisitions or disposals of assets or businesses. The new
 definition requires that when substantially all of the fair value
 of the gross assets acquired or disposed of is concentrated in a
 single identifiable asset or group of similar identifiable assets,
 the asset or group is not a business. The update will require that
 to be considered a business, a set of assets and activities must
 include, at a minimum, an input and a substantive process that
 together significantly contribute to the ability to create output.
 Additionally, the update will remove the evaluation of whether a
 market participant could replace missing elements in order to
 consider the set of assets and activities a business, will provide
 more stringent criteria for sets without outputs and will narrow
 the definition of output. The new standard is effective for interim
 and annual reporting periods beginning after December&#xA0;15,
 2017, although early adoption is permitted for certain
 transactions. The prospective transition method will be required
 for this new guidance. Quanta is currently evaluating the potential
 impact of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&#xA0;1,
 2018.</p>

 intended to simplify the subsequent measurement of goodwill by
 eliminating the second step in the current two-step goodwill
 impairment test. The update will require an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity will
 recognize an impairment charge for the amount by which the carrying
 amount exceeds the reporting unit&#x2019;s fair value, if
 applicable. Additionally, the update will eliminate the requirement
 that a reporting unit with a zero or negative carrying amount
 perform a qualitative assessment and the second step of the
 two-step goodwill impairment test and will instead require
 disclosure of the amount of goodwill allocated to each reporting
 unit with a zero or negative carrying amount of net assets. This
 update is effective for public entities for interim and annual
 reporting periods beginning after December&#xA0;15, 2019, although
 early adoption is permitted for interim and annual goodwill
 impairment tests performed on testing dates after January&#xA0;1,
 2017. The prospective transition method will be required for this
 new guidance. Quanta is currently evaluating the potential impact
 of this authoritative guidance on its consolidated financial
 statements and will adopt this guidance by January&#xA0;1,
 2020.</p>

 The results of four of the acquired companies are generally
 included in Quanta&#x2019;s Electric Power Infrastructure Services
 segment. These companies included an electrical infrastructure
 services company located in Australia, a utility contracting
 company located in Canada, a full service medium- and high-voltage
 powerline contracting company located in the United States and a
 telecommunications company located in Canada. Quanta also acquired
 a pipeline service contractor located in the United States, the
 results of which are generally included in Quanta&#x2019;s Oil and
 Gas Infrastructure Services segment. The aggregate consideration
 for these acquisitions consisted of $75.9&#xA0;million paid or
 payable in cash, subject to certain adjustments, 70,840 shares of
 Quanta common stock valued at $1.5&#xA0;million as of the
 settlement date of the applicable acquisition, and contingent
 consideration payments of up to $39.5 million, which will be paid
 if certain financial targets are achieved. Based on the estimated
 fair value of this contingent consideration, Quanta recorded an
 $18.7 million liability. As these transactions were effective
 during 2016, the results have been included in Quanta&#x2019;s
 consolidated financial statements beginning on the respective dates
 of acquisition. These acquisitions should enable Quanta to further
 enhance its service offerings in the United States, Australia and
 Canada.</p>

 assessments of the fair values of the acquired assets and assumed
 liabilities related to businesses acquired subsequent to
 March&#xA0;31, 2016, and further adjustments to the purchase price
 allocations may occur. Quanta expects to complete the purchase
 accounting process as soon as practicable but no later than one
 year from the acquisition dates with possible updates primarily
 related to certain tax estimates. The aggregate purchase
 consideration of these businesses acquired in 2016 subsequent to
 March&#xA0;31, 2016 was preliminarily allocated to acquired assets
 and assumed liabilities, which resulted in a preliminary allocation
 of $17.0&#xA0;million of net tangible assets, $18.4 million of
 goodwill and $3.1 million of other intangible assets.</p>

 strategically expanded Quanta&#x2019;s Canadian, Australian and
 domestic electric power, oil and gas service and communications
 offerings, which Quanta believes contributes to the recognition of
 the goodwill. In connection with the 2016 acquisitions, goodwill of
 $24.2 million was recorded for the acquired businesses that were
 included within Quanta&#x2019;s Electric Power Infrastructure
 Services Division and $20.3&#xA0;million was recorded for acquired
 businesses that were included within Quanta&#x2019;s Oil and Gas
 Infrastructure Services Division on the dates of acquisition.
 Goodwill of $2.0&#xA0;million related to the 2016 acquisitions is

 adjusting the historical results of Quanta to include the
 historical results of the 2016 acquisitions as if they occurred
 January&#xA0;1, 2015. These pro forma combined historical results
 were also adjusted for the following: a reduction of interest
 expense as a result of the repayment of outstanding indebtedness of
 the acquired businesses, a reduction of interest income as a result
 of the cash consideration paid net of cash received, an increase in
 amortization expense due to the incremental intangible assets
 recorded related to the 2016 acquisitions, an increase or decrease
 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&#x2019;s accounting policies, an increase in the number of
 outstanding shares of Quanta common stock and certain
 reclassifications to conform the acquired companies&#x2019;
 presentation to Quanta&#x2019;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 resulted or may result from the 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.</p>

Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final.  May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.</p></div>

 provides for a $1.81 billion senior secured revolving credit
 facility maturing on December&#xA0;18, 2020. The entire amount
 available under the facility may be used by Quanta for revolving
 loans and letters of credit in U.S. dollars and certain alternative
 currencies. Up to $600.0 million of the facility may be used by
 certain subsidiaries of Quanta for revolving loans and letters of
 credit in certain alternative currencies. Up to $100.0 million of
 the facility may be used for swing line loans in U.S. dollars, up
 to $50.0 million of the facility may be used for swing line loans
 in Canadian dollars and up to $30.0 million of the facility may be
 used for swing line loans in Australian dollars. In addition,
 subject to the conditions specified in the credit agreement, Quanta
 has the option to increase the revolving commitments by up to
 $400.0 million from time to time upon receipt of additional
 commitments from new or existing lenders. Borrowings under the
 credit agreement are to be used to refinance existing indebtedness
 and for working capital, capital expenditures and other general
 corporate purposes.</p>

 entered into an accelerated share repurchase arrangement (the ASR)
 to repurchase $750.0 million of its common stock under the 2015
 Repurchase Program. Under the terms of the ASR, Quanta paid $750.0
 million to JPMorgan Chase Bank, National Association, London Branch
 (JPMorgan) and initially received 25.7&#xA0;million shares of its
 common stock. The fair market value of these 25.7&#xA0;million
 shares at the time of delivery was $600.0 million, and the
 repurchased shares and the related cost to acquire them were
 accounted for as an adjustment to the balance of treasury stock
 during the third quarter of 2015, reducing the weighted-average
 number of basic and diluted common shares used to calculate
 Quanta&#x2019;s earnings per share. The $150.0 million remaining
 under the ASR was recorded as an adjustment to APIC during the
 third quarter of 2015 and was reclassified from APIC to treasury
 stock upon final settlement of the ASR on April&#xA0;12, 2016. At
 final settlement and based on the final volume-weighted average
 share price during the term of the ASR, minus a discount and
 subject to other adjustments pursuant to the terms and conditions
 of the ASR, Quanta received 9.4&#xA0;million additional shares of
 its common stock from JPMorgan. The 2015 Repurchase Program ended
 on February&#xA0;28, 2017, and Quanta repurchased a total of
 54.3&#xA0;million shares of its common stock at a cost of $1.20
 billion under the 2015 Repurchase Program. No common stock was
 repurchased in the three months ended March&#xA0;31, 2017 or 2016
 under any repurchase programs.</p>

 believes most significantly influences the economic performance of
 the joint venture. Management has concluded that Quanta is the
 primary beneficiary of each of the joint ventures determined to be
 VIEs and has accounted for each on a consolidated basis. The other
 parties&#x2019; equity interests in these joint ventures have been
 accounted for as non-controlling interests in the condensed
 consolidated financial statements. Income attributable to the other
 joint venture members in the amounts of $0.2 million and $0.4
 million for the three months ended March&#xA0;31, 2017 and 2016 has
 been accounted for as a reduction of net income in deriving net
 income attributable to common stock. Equity in the consolidated
 assets and liabilities of these joint ventures that is attributable
 to the other joint venture members has been accounted for as
 non-controlling interests within total equity in the accompanying
 balance sheets.</p>

 of investments held by the non-controlling interests in these
 variable interest entities at March&#xA0;31, 2017 and
 December&#xA0;31, 2016 was $2.5 million and $3.3 million. During
 the three months ended March&#xA0;31, 2017 and 2016, distributions

 approved the 2011 Omnibus Equity Incentive Plan (the 2011 Plan).
 The 2011 Plan provides for the award of non-qualified stock
 options, incentive (qualified) stock options, stock appreciation
 rights, restricted stock, RSUs, stock bonus awards, performance
 compensation awards (including performance units and cash bonus
 awards) or any combination of the foregoing. The purpose of the
 2011 Plan is to attract and retain key personnel and provide
 participants with additional performance incentives by increasing
 their proprietary interest in Quanta. Employees, directors,
 officers, consultants or advisors of Quanta or its affiliates are
 eligible to participate in the 2011 Plan, as are prospective
 employees, directors, officers, consultants or advisors of Quanta
 who have agreed to serve Quanta in those capacities. An aggregate
 of 11,750,000 shares of Quanta common stock may be issued pursuant
 to awards granted under the 2011 Plan.</p>

 employees, directors, and certain consultants and advisors. An
 aggregate of 4,000,000 shares of common stock may be issued
 pursuant to awards granted under the 2007 Plan, and the 2007 Plan
 terminates on May&#xA0;24, 2017. Quanta also has a Restricted Stock

 in equal installments over a two-year or three-year period

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">As described in Note&#xA0;8, Quanta holds
 investments in certain joint ventures with third parties for the
 purpose of providing infrastructure services under certain customer
 contracts. Losses incurred by these joint ventures are generally
 shared ratably based on the percentage ownership of the joint
 venture members. However, each member of the joint venture
 typically is jointly and severally liable for all of the
 obligations of the joint venture under the contract with the
 customer, and therefore can be liable for full performance of the
 contract with the customer. In circumstances where Quanta&#x2019;s
 participation in a joint venture qualifies as a general
 partnership, the joint venture partners are jointly and severally
 liable for all of the obligations of the joint venture, including
 obligations owed to the customer or any other person or entity.
 Quanta is not aware of circumstances that would lead to future
 claims against it for material amounts in connection with these
 joint and several liabilities.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">In the joint venture arrangements entered into by
 Quanta, typically each joint venture party indemnifies the other
 party for any liabilities incurred in excess of the liabilities
 such other party is obligated to bear under the respective joint
 venture agreement. It is possible, however, that Quanta could be
 required to pay or perform obligations in excess of its share if
 the other party to the joint venture failed or refused to pay or
 perform its share of the obligations. Quanta is not aware of
 circumstances that would lead to future claims against it for
 material amounts that would not be indemnified.</p>

 is a partner was selected for an engineering, procurement and

 approximately 500 kilometers of transmission line and two 500 kV
 substations. Quanta will provide turnkey EPC services for the
 entire project. As of March&#xA0;31, 2017, Quanta had made
 aggregate contributions to this unconsolidated affiliate of $16.9
 million and had received $2.9 million as a return of capital. Also
 as of March&#xA0;31, 2017, Quanta had outstanding additional

 ordinary course of business. These actions typically seek, among
 other things, compensation for alleged personal injury, breach of
 contract and/or property damages, employment-related damages,
 punitive damages, civil penalties or other losses, or injunctive or
 declaratory relief. With respect to all such lawsuits, claims and
 proceedings, Quanta records a reserve when it is probable that a
 liability has been incurred and the amount of loss can be
 reasonably estimated. In addition, Quanta discloses matters for
 which management believes a material loss is at least reasonably
 possible. Except as otherwise stated below, none of these
 proceedings, separately or in the aggregate, are expected to have a
 material adverse effect on Quanta&#x2019;s consolidated financial
 position, results of operations or cash flows. In all instances,
 management has assessed the matter based on current information and
 made a judgment concerning its potential outcome, giving due

 Inc., et al.</i>&#xA0;In June 2006, plaintiff Lorenzo Benton filed
 a class action complaint in the Superior Court of California,
 County of Los Angeles, alleging various wage and hour violations
 against Telecom Network Specialists (TNS), a former subsidiary of
 Quanta.&#xA0;Quanta retained liability associated with this matter
 pursuant to the terms of Quanta&#x2019;s sale of TNS in December
 2012. Benton seeks to represent a class of workers that includes
 all persons who worked on certain TNS projects, including
 individuals that TNS retained through numerous staffing
 agencies.&#xA0;The plaintiff class in this matter is seeking
 damages for unpaid wages, penalties associated with the failure to
 provide meal and rest periods and overtime wages, interest and
 attorneys&#x2019; fees. In September 2015, the trial court certified
 the class as to workers from the various staffing companies at
 issue. In January 2017, the trial court granted a summary judgment
 motion filed by the plaintiff class and found that TNS was a joint
 employer of the class members and that it failed to provide
 adequate meal and rest breaks and failed to pay overtime wages.
 Quanta believes this decision is not supported by controlling law
 and continues to contest liability in this matter.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Additionally, in November 2007, TNS filed cross
 complaints for indemnity and breach of contract against the
 staffing agencies, which employed many of the individuals in
 question. In December 2012, the trial court heard cross-motions for
 summary judgment filed by TNS and the staffing agencies pertaining
 to TNS&#x2019;s demand for indemnity.&#xA0;The court denied
 TNS&#x2019;s motion and granted the motions filed by the staffing
 agencies; however, the California Appellate Court reversed the
 trial court&#x2019;s decision in part and instructed the trial court
 to reconsider its ruling.&#xA0;In February 2017, the court denied a
 new motion for summary judgment filed by the staffing companies and
 stated that the staffing companies were liable to TNS for any
 damages owed to the class members that the staffing companies
 employed.</p>

 connection with this matter remains the subject of pending
 litigation and will ultimately depend on various factors, including
 the outcome of Quanta&#x2019;s appeal of the trial court&#x2019;s
 ruling and the solvency of the staffing agencies. Based on review
 and analysis of the trial court&#x2019;s rulings, Quanta does not
 believe, at this time, that it is probable this matter will result
 in a material loss; however, a loss up to approximately $23 million
 remains reasonably possible upon final resolution of this
 matter.</p>

 <b><i>Concentrations of Credit Risk</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">Quanta is subject to concentrations of credit risk
 related primarily to its cash and cash equivalents and net
 receivable position with customers, which includes amounts related
 to billed and unbilled accounts receivable and costs and estimated
 earnings in excess of billings on uncompleted contracts net of
 advanced billings with the same customer. Substantially all of
 Quanta&#x2019;s cash and cash equivalents are managed by what it
 believes to be high credit quality financial institutions. In
 accordance with Quanta&#x2019;s investment policies, these
 institutions are authorized to invest cash and cash equivalents in
 a diversified portfolio of what Quanta believes to be high quality
 cash and cash equivalent investments, which consist primarily of
 interest-bearing demand deposits, money market investments, 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 cash and cash
 equivalents is subject to any material risk of loss, changes in
 economic conditions could impact the interest income Quanta
 receives from these investments. In addition, Quanta grants credit
 under normal payment terms, generally without collateral, to its
 customers, which include electric power and oil and gas companies,
 governmental entities, general contractors, and builders, owners
 and managers of commercial and industrial properties located
 primarily in the United States, Canada and Australia. Consequently,
 Quanta is subject to potential credit risk related to changes in
 business and economic factors throughout the United States, Canada
 and Australia, which may be heightened as a result of uncertain
 economic and financial market conditions that have existed in
 recent years. However, Quanta generally has certain statutory lien
 rights with respect to services provided. Historically, some of
 Quanta&#x2019;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.</p>

 one customer within Quanta&#x2019;s Electric Power Infrastructure
 Services segment accounted for approximately 16% of Quanta&#x2019;s
 consolidated net receivable position. The net receivable position
 for this customer was $300.4 million and $277.3 million at
 March&#xA0;31, 2017 and December&#xA0;31, 2016 and was related to
 two electric transmission projects located in remote regions of
 northeastern Canada. Included in the net receivable position for
 this customer were $191.1 million and $175.9 million of costs and
 estimated earnings in excess of billings on uncompleted contracts
 at March&#xA0;31, 2017 and December&#xA0;31, 2016. These net
 receivable balances were related to invoicing challenges and
 billing delays that resulted from extensive quality assurance
 documentation and administrative requirements. Quanta continues to
 work collaboratively with the customer to improve these processes.
 The net receivable position also included change orders and claims
 that Quanta is negotiating in the normal course of business. No
 other customers represented 10% or more of Quanta&#x2019;s
 consolidated net receivable position as of March&#xA0;31, 2017 or

 of credit to ensure reimbursement for amounts they are disbursing

 self-funded insurance programs. In addition, from time to time,
 certain customers require Quanta to post letters of credit to
 ensure payment to its subcontractors and vendors and to guarantee
 performance under contracts. Such letters of credit are generally
 issued by a bank or similar financial institution, typically
 pursuant to Quanta&#x2019;s credit facility. Each 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.
 Depending on the circumstances of such a reimbursement, Quanta may
 also be required to record a charge to earnings for the
 reimbursement. Quanta does not believe that it is likely that any
 material claims will be made under a letter of credit in the
 foreseeable future.</p>

 provide performance bonds in connection with its contractual
 commitments. Quanta has indemnified its sureties for any expenses
 paid out under these performance bonds. These performance bonds
 expire at various times ranging from mechanical completion of the
 related projects to a period extending beyond contract completion
 in certain circumstances, and as such a determination of maximum
 potential amounts outstanding requires the use of certain estimates
 and assumptions. Such amounts can also fluctuate from period to
 period based upon the mix and level of Quanta&#x2019;s bonded
 operating activity. As of March&#xA0;31, 2017, the total amount of
 the outstanding performance bonds was estimated to be approximately
 $3.4&#xA0;billion. Quanta&#x2019;s estimated maximum exposure as it
 relates to the value of the performance bonds outstanding is
 lowered on each bonded project as the cost to complete is reduced,
 and each of its commitments under the performance bonds generally
 extinguishes concurrently with the expiration of its related
 contractual obligation. The estimated cost to complete these bonded
 projects was approximately $910 million as of March&#xA0;31,

 to various collective bargaining agreements with unions that
 represent certain of their employees. The collective bargaining
 agreements expire at various times and have typically been
 renegotiated and renewed on terms similar to those in the expiring
 agreements. From time to time, Quanta is a party to grievance
 actions based on claims arising out of the collective bargaining
 agreements. The agreements require the operating units to pay
 specified wages, provide certain benefits to their union employees
 and contribute certain amounts to multiemployer pension plans and
 employee benefit trusts. Quanta&#x2019;s multiemployer pension plan
 contribution rates generally are specified in the collective
 bargaining agreements (usually on an annual basis), and
 contributions are made to the plans on a
 &#x201C;pay-as-you-go&#x201D; basis based on its union employee
 payrolls. The location and number of union employees that Quanta
 employs at any given time and the plans in which they may
 participate vary depending on the projects Quanta has ongoing at
 any time and the need for union resources in connection with those
 projects. Therefore, Quanta is unable to accurately predict its
 union employee payroll and the amount of the resulting
 multiemployer pension plan contribution obligation for future
 periods.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">The Pension Protection Act of 2006 (PPA) also added

 endangered&#x201D; or &#x201C;critical&#x201D; status based on
 multiple factors (including, for example, the plan&#x2019;s funded
 percentage, cash flow position and whether it is projected to
 experience a minimum funding deficiency). Plans in these
 classifications must adopt measures to improve their funded status
 through a funding improvement or rehabilitation plan, as
 applicable, which may require additional contributions from
 employers (which may take the form of a surcharge on benefit
 contributions) and/or modifications to retiree benefits. Certain
 plans to which Quanta contributes or may contribute in the future
 are in &#x201C;endangered,&#x201D; &#x201C;seriously endangered&#x201D;
 or &#x201C;critical&#x201D; status. The amount of additional funds,
 if any, that Quanta may be obligated to contribute to these plans
 in the future cannot be estimated due to uncertainty of the future
 levels of work that require the specific use of union employees
 covered by these plans, as well as the future contribution levels
 and possible surcharges on contributions applicable to these
 plans.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Quanta may be subject to additional liabilities
 imposed by law as a result of its participation in multiemployer
 defined benefit pension plans. For example, the Employee Retirement
 Income Security Act of 1974, as amended by the Multiemployer
 Pension Plan Amendments Act of 1980, imposes certain liabilities
 upon an employer who is a contributor to a multiemployer pension
 plan if the employer withdraws from the plan or the plan is
 terminated or experiences a mass withdrawal. These liabilities
 include an allocable share of the unfunded vested benefits in the
 plan for all plan participants, not merely the benefits payable to
 a contributing employer&#x2019;s own retirees. As a result,
 participating employers may bear a higher proportion of liability
 for unfunded vested benefits if other participating employers cease
 to contribute or withdraw, with the reallocation of liability being
 more acute in cases when a withdrawn employer is insolvent or
 otherwise fails to pay its withdrawal liability. Other than as
 described below, Quanta is not aware of any material amounts of
 withdrawal liability that have been incurred as a result of a
 withdrawal by any of Quanta&#x2019;s operating units from any
 multiemployer defined benefit pension plans.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"><i>2011 Central States Plan Withdrawal
 Liability.</i> In the fourth quarter of 2011, certain Quanta
 subsidiaries withdrew from the Central States, Southeast and
 Southwest Areas Pension Plan (the Central States Plan). This
 withdrawal event was the result of an amendment to a collective
 bargaining agreement with the International Brotherhood of
 Teamsters (Teamsters) that eliminated certain employers&#x2019;
 obligations to contribute to the Central States Plan, which was
 then in critical status and significantly underfunded as to its
 vested benefit obligations. The amendment was negotiated by the
 Pipe Line Contractors Association (PLCA) on behalf of its members,
 which include certain Quanta subsidiaries. Because certain other
 Quanta subsidiaries continued participation in the Central States
 Plan into 2012, the Quanta subsidiaries&#x2019; withdrawals in 2011
 effected only a partial withdrawal on behalf of Quanta for 2011.
 Quanta believed that the partial withdrawal was advantageous
 because it limited exposure to increased liability resulting from a
 future withdrawal event, at which point the Central States Plan
 could have been further underfunded. Quanta and other PLCA members
 now contribute to a different multiemployer pension plan on behalf
 of the affected Teamsters employees. While certain additional
 Quanta subsidiaries continued participation in the Central States
 Plan into 2012, Quanta believes that such subsidiaries withdrew
 from the Central States Plan in 2012, thereby effecting a complete
 withdrawal as of December&#xA0;30, 2012 for all Quanta
 subsidiaries.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">In connection with the partial withdrawal in 2011,
 Quanta recorded a withdrawal liability of approximately $32.6
 million in the fourth quarter of 2011 based on estimates received
 from the Central States Plan. The Central States Plan subsequently
 asserted that the withdrawal of the PLCA members, and thus
 Quanta&#x2019;s partial withdrawal, was not effective in 2011. The
 PLCA and Quanta believed at that time that a legally effective
 withdrawal had occurred during the fourth quarter of 2011, and this
 issue was litigated in the federal district court for the Northern
 District of Illinois, Eastern Division. In September 2013, the
 district court ruled in favor of the Central States Plan, and that
 decision was appealed by the PLCA. In July 2014, the Central States
 Plan provided Quanta with a Notice and Demand claiming partial
 withdrawal liability in the amount of $39.6 million and requiring
 Quanta to make payments on this assessment while the dispute is
 ongoing. In September 2015, the United States Court of Appeals for
 the Seventh Circuit ruled in favor of the PLCA and reversed the
 district court&#x2019;s previous ruling which had been in favor of
 the Central States Plan. Based on the outcome of the appeal, in
 January 2016, the Central States Plan issued a revised Notice and
 Demand claiming a partial withdrawal liability in the amount of
 $32.9 million.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">Separately, in December 2013, the Central States
 Plan filed lawsuits against two of Quanta&#x2019;s other
 subsidiaries in connection with their withdrawal in 2012. In the
 first lawsuit, the Central States Plan alleged that the subsidiary
 elected to participate in the Central States Plan pursuant to the
 collective bargaining agreement under which it participated. Quanta
 argued that no such election was made and that any payments made to
 the Central States Plan were made in error. In July 2014, the
 parties reached an agreement to settle the lawsuit, and the court
 dismissed the case with prejudice. In the second lawsuit, the
 Central States Plan alleged that contributions made by the Quanta
 subsidiary to a new industry fund created after Quanta withdrew
 from the Central States Plan should have been made to the Central
 States Plan. This arguably would have extended the withdrawal date
 for this subsidiary to at least the end of 2013. Quanta disputed
 these allegations on the basis that it properly paid contributions
 to the new industry fund based on the terms of the collective
 bargaining agreement under which it participated and asserted that
 it terminated its obligation to contribute to the Central States
 Plan by the end of 2012. The parties both moved for summary
 judgment, and in March 2015, the court entered judgment in favor of
 Quanta. The Central States Plan filed a notice of appeal in April
 2015, and in December 2015, the Central States Plan agreed to
 dismiss the appeal with prejudice.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">The ultimate liability associated with the complete
 withdrawal of Quanta&#x2019;s subsidiaries from the Central States
 Plan will depend on various factors, including interpretations of
 the terms of the collective bargaining agreements under which the
 subsidiaries participated and whether exemptions from withdrawal
 liability applicable to construction industry employers will be
 available. In March 2014, the Central States Plan provided revised
 estimates indicating that the total withdrawal liability based on
 certain withdrawal scenarios from 2011 through 2014 could range
 between $40.1 million and $55.4 million, which Quanta believes to
 be the range of reasonably possible loss for this matter.
 Additionally, based on those estimates and allowing for the
 exclusion of amounts believed by management to have been improperly
 included in such estimates, Quanta recorded an adjustment to cost
 of services during the three months ended March&#xA0;31, 2014 to
 increase the recognized withdrawal liability to an amount within
 the range communicated to Quanta by the Central States Plan. Given
 the unknown nature of some of the factors mentioned above, the
 final withdrawal liability cannot yet be determined with certainty.
 Accordingly, it is reasonably possible that the amount owed upon
 final resolution of these matters could be materially higher than
 the expense Quanta had recognized through March&#xA0;31, 2017.
 Although Quanta disputes the total liability owed to the Central
 States Plan, it continues to make monthly payments according to the
 terms of the January 2016 Notice and Demand while the parties
 determine the final withdrawal liability. As of March&#xA0;31,
 2017, Quanta had made payments totaling $19.1 million toward the
 withdrawal liability assessment.</p>

 Liability.</i> On October&#xA0;9, 2013, Quanta acquired a company
 that experienced a complete withdrawal from the Central States Plan
 prior to the date of acquisition. Prior to the acquisition, the
 Central States Plan issued a Notice and Demand to the acquired
 company claiming a withdrawal liability in the total amount of $6.9
 million and requiring payments to be made on this assessment while
 the dispute is ongoing. In connection with the acquisition, Quanta
 recorded an initial liability of $4.8 million related to this
 withdrawal liability, and a portion of the purchase price for the
 acquired company was deposited into an escrow account to fund any
 withdrawal obligation in excess of the initial liability recorded.
 In January 2016, the Central States Plan issued a revised Notice
 and Demand claiming a withdrawal liability in the amount of $4.8
 million. Although Quanta continues to dispute the total liability
 owed to the Central States Plan, it continues to make monthly
 payments according to the terms of this revised Notice and Demand
 while the parties determine the final withdrawal liability. As of
 March&#xA0;31, 2017, payments totaling $3.7 million had been made
 toward the withdrawal liability assessment.</p>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify">Quanta generally indemnifies its customers for the
 services it provides under its contracts, as well as other
 specified liabilities, which may subject Quanta to indemnity claims
 and liabilities and related litigation. Additionally, in connection
 with certain acquisitions and dispositions, Quanta has indemnified
 various parties against specified liabilities that those parties
 might incur in the future. The indemnities under acquisition or
 disposition agreements are usually contingent upon the other party
 incurring liabilities that reach specified thresholds. As of
 March&#xA0;31, 2017, except as otherwise set forth above in
 <i>Legal Proceedings</i>, Quanta does not believe any material
 liabilities for claims exist against it in connection with any of
 these indemnity obligations.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">In the normal course of Quanta&#x2019;s acquisition
 transactions, Quanta obtains rights to indemnification from the
 sellers or former owners of acquired companies for certain risks,
 liabilities and obligations arising from their prior operations,
 such as performance, operational, safety, workforce or tax issues,
 some of which Quanta may not have discovered during due diligence.
 However, the indemnities may not cover all of Quanta&#x2019;s
 exposure for such pre-acquisition matters, and the indemnitors may
 be unwilling or unable to pay the amounts owed to Quanta.
 Accordingly, Quanta may incur expenses for which it is not
 reimbursed. Quanta is currently in the process of identifying
 certain pre-acquisition obligations associated with non-U.S.
 payroll taxes that may be due from a business acquired by Quanta in
 2013. As of March&#xA0;31, 2017, Quanta had recorded $11.4 million
 as its best estimate of the pre-acquisition tax obligations and a
 corresponding indemnification asset, as management expects to
 recover from the indemnity counterparties any amounts that Quanta
 may be required to pay in connection with any such obligations.</p>

 segments: (1)&#xA0;Electric Power Infrastructure Services and
 (2)&#xA0;Oil and Gas Infrastructure Services. This structure is
 generally based on the broad end-user markets for Quanta&#x2019;s
 services. See Note&#xA0;1 for additional information regarding
 Quanta&#x2019;s reportable segments.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &quot;Times New Roman&quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify">Quanta&#x2019;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&#x2019;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&#x2019;s operating units
 are organized into one of two internal divisions, namely, the
 Electric Power Infrastructure Services Division and the Oil and Gas
 Infrastructure Services Division. These internal divisions are
 closely aligned with the reportable segments described above based
 on their operating units&#x2019; predominant type of work.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &quot;Times New Roman&quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify">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&#x2019;s market strategies. These classifications
 of Quanta&#x2019;s operating unit revenues by type of work for
 segment reporting purposes can at times require judgment on the
 part of management. Quanta&#x2019;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 service across industries. For
 example, Quanta performs joint trenching projects to install
 distribution lines for electric power and natural gas
 customers.</p>

 and common administrative support at each of its operating units
 require that certain allocations of shared and indirect costs, such
 as facility costs and indirect operating expenses, including
 depreciation and general and administrative costs, be 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
 intangible assets are not allocated.</p>

 The consolidated financial statements also include the accounts of

 either consolidated or proportionately consolidated, as discussed
 in the following summary of significant accounting policies.
 Investments in affiliated entities in which Quanta does not have a
 controlling financial interest, but over which Quanta has
 significant influence, usually because Quanta holds a voting
 interest of between 20% and 50%, are accounted for using the equity
 method. All significant intercompany accounts and transactions have
 been eliminated in consolidation. Unless the context requires
 otherwise, references to Quanta include Quanta Services, Inc. and

 all adjustments, consisting only of normal recurring adjustments,

 conformity with US&#xA0;GAAP 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 amounts 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&#x2019;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&#x2019;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, equity and other investments, loan receivables,
 purchase price allocations, liabilities for self-insured and other
 claims and guarantees, multiemployer pension plan withdrawal
 liabilities, revenue recognition for construction contracts
 inclusive of contractual change orders and claims, share-based
 compensation, operating results of reportable segments, as well as
 the provision for income taxes and the calculation of uncertain tax

 million and $112.2 million as of March&#xA0;31, 2017 and
 December&#xA0;31, 2016. Cash consisting of interest-bearing demand
 deposits is carried at cost, which approximates fair value. Quanta
 considers all highly liquid investments with an original maturity
 of three months or less at the time of purchase to be cash
 equivalents, which are carried at fair value. At March&#xA0;31,
 2017 and December&#xA0;31, 2016, cash equivalents were $8.1 million
 and $8.8 million, and consisted primarily of money market
 investments and money market mutual funds and are discussed further
 in&#xA0;<i>Fair Value

 2017 and December&#xA0;31, 2016, cash and cash equivalents held in
 domestic bank accounts were $17.5 million and $19.5 million, and
 cash and cash equivalents held in foreign bank accounts were $89.0
 million and $92.7 million. As of March&#xA0;31, 2017 and
 December&#xA0;31, 2016, cash and cash equivalents held by
 Quanta&#x2019;s investments in joint ventures, which are either
 consolidated or proportionately consolidated, were $8.8 million and
 $11.5 million, of which $7.7 million and $10.0 million related to
 domestic joint ventures. Cash and cash equivalents held by the
 joint ventures are available to support the operations of the
 related joint ventures, but Quanta does not have access to that
 cash and cash equivalents for its other operations. Under the terms
 of the partnership agreements, Quanta generally has no right to the

 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
 regarding, among other factors, the customer&#x2019;s access to
 capital, the customer&#x2019;s willingness or ability to pay,
 general economic and market conditions, the ongoing relationship
 with the customer and uncertainties related to the resolution of
 disputed matters. Quanta considers accounts receivable delinquent
 after 30&#xA0;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&#xA0;days. In addition to balances that have been outstanding
 for 90&#xA0;days or more, Quanta also includes accounts receivable
 balances that relate to customers in bankruptcy or with other known
 difficulties in its analysis of the allowance for doubtful
 accounts. Material changes in Quanta&#x2019;s customers&#x2019;
 business or cash flows, which may be impacted by negative economic
 and market conditions, could affect Quanta&#x2019;s ability to
 collect amounts due from them. As of March&#xA0;31, 2017 and
 December&#xA0;31, 2016, Quanta had allowances for doubtful accounts
 on current receivables of $5.0 million and $2.8 million. Long-term
 accounts receivable are included within other assets.</p>

 historical acquisitions of companies. Upon acquisition, these
 companies were either combined into one of Quanta&#x2019;s existing
 operating units or managed on a stand-alone basis as an individual
 operating unit. Goodwill recorded in connection with these
 acquisitions is subject to an annual assessment for impairment,
 which Quanta performs at the operating unit level for each
 operating unit that carries a balance of goodwill. Each of
 Quanta&#x2019;s operating units is organized into one of two
 internal divisions: the Electric Power Infrastructure Services
 Division and the Oil and Gas Infrastructure Services Division. As
 most of the companies acquired by Quanta provide multiple types of
 services for multiple types of customers, these divisional
 designations are based on the predominant type of work performed by
 each operating unit at the point in time the divisional designation
 is made. Goodwill is required to be measured for impairment at the
 reporting unit level, which represents the operating segment level
 or one level below the operating segment level for which discrete
 financial information is available. Quanta has determined that its
 individual operating units represent its reporting units for the
 purpose of assessing goodwill impairments.</p>

 factors to determine whether it is necessary to perform the
 two-step fair value-based impairment test described below. If
 Quanta 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. Quanta can
 choose to perform the qualitative assessment on none, some or all
 of its reporting units. Quanta 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 the
 qualitative assessment in any subsequent period. Qualitative
 indicators including deterioration in macroeconomic conditions,
 declining financial performance, or a sustained decrease in share
 price, among other things, may trigger the need for annual or
 interim impairment testing of goodwill associated with one or all
 of the reporting units.</p>

 performed at year-end, or more frequently if events or
 circumstances arise which indicate that goodwill may be impaired.
 For instance, a decrease in Quanta&#x2019;s market capitalization
 below book value, a significant change in business climate or loss
 of a significant customer, as well as the qualitative indicators
 referenced above, may trigger the need for interim impairment
 testing of goodwill for 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&#x2019;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&#x2019;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.</p>

 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&#x2019;s opinion, this method currently results in the
 most accurate calculation of a reporting unit&#x2019;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, among others, revenue growth
 rates, operating margins, discount rates, weighted average costs of
 capital and future market conditions. 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.</p>

 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
 one-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&#x2019;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.</p>

 approaches, Quanta determines the estimated fair value of each of
 its reporting units by applying transaction multiples to each
 reporting unit&#x2019;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.</p>

 impairment test may indicate an implied fair value that is
 substantially similar to the reporting unit&#x2019;s carrying value.
 Such similarities in value are generally an indication that
 management&#x2019;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.</p>

 fair-value based goodwill impairment analysis was performed for
 each of Quanta&#x2019;s reporting units, and no reporting units were
 evaluated solely on a qualitative basis. Step one of the analysis
 indicated that the implied fair value of each of Quanta&#x2019;s
 reporting units, other than recently acquired reporting units and
 the reporting units that recorded goodwill impairment charges in
 2015, was substantially in excess of its carrying value.</p>

 2016 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&#x2019;s reporting units were operating.
 Additionally, management considered the sensitivity of its fair
 value estimates to changes in certain valuation assumptions. After
 taking into account a 10% decrease in the fair value of each of
 Quanta&#x2019;s reporting units, two reporting units within
 Quanta&#x2019;s Oil and Gas Infrastructure Division had fair values
 below their respective carrying values. Quanta recorded asset
 impairment charges for these reporting units in 2015. The fair
 values determined in 2016 for these reporting units were consistent
 with the fair values determined in 2015, accordingly the fair
 values approximate the current carrying values. Circumstances such
 as market declines, unfavorable economic conditions, the loss of a
 major customer or other factors could increase the risk of
 impairment of goodwill in future periods.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &quot;Times New Roman&quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify">If an operating unit experiences prolonged periods
 of declining revenues, operating margins or both, it may be at risk
 of failing step one of the goodwill impairment test. Certain
 operating units have experienced declines over the short-term due
 to challenging macroeconomic conditions in certain geographic areas
 and low oil and natural gas prices, which have negatively impacted
 customer spending and resulted in project cancellations and delays.
 Additionally, customer capital spending has been constrained as a
 result of an increasingly complex regulatory and permitting
 environment. Certain operating units within Quanta&#x2019;s Oil and
 Gas Infrastructure Services Division that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors. Goodwill and intangible
 assets associated with the operating units within Quanta&#x2019;s
 Oil and Gas Infrastructure Services Division that have been
 significantly impacted by the factors mentioned above were $69.8
 million and $11.7 million at March&#xA0;31, 2017. Quanta monitors
 these conditions and others to determine if it is necessary to
 perform step one of the fair-value based impairment test for one or
 more operating units prior to the annual impairment assessment. No
 interim impairment charges were recorded during the three months
 ended March&#xA0;31, 2017. Although Quanta is not aware of
 circumstances that would lead to a goodwill impairment at a
 reporting unit currently, circumstances such as a continued market
 decline, the loss of a major customer or other factors could impact
 the valuation of goodwill in the future.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &quot;Times New Roman&quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify">Quanta&#x2019;s intangible assets include customer
 relationships, backlog, trade names, non-compete agreements,
 patented rights and developed technology, all subject to
 amortization. The value of customer relationships is estimated as
 of the date a business is acquired based on 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 and estimated customer attrition rates, the
 importance or lack thereof of existing customer relationships to
 Quanta&#x2019;s business plan, income taxes and required rates of
 return. Quanta values backlog for acquired businesses as of the
 acquisition date 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.</p>

 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.</p>

 primary beneficiary consolidating the VIE must normally have both
 (i)&#xA0;the power to direct the activities of a VIE that most
 significantly affect the VIE&#x2019;s economic performance and
 (ii)&#xA0;the obligation to absorb losses of the VIE or the right
 to receive benefits from the VIE, in either case 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&#x2019;s equity interest in the VIE is accounted for as a
 non-controlling interest. In cases where Quanta determines that it
 has an undivided interest in the assets, liabilities, revenues and
 profits of an unincorporated VIE (e.g., a general partnership
 interest), such amounts are consolidated on a basis proportional to
 Quanta&#x2019;s ownership interest in the unincorporated entity.</p>

 earnings (losses) of unconsolidated affiliates in the consolidated
 statements of operations when applicable. 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 related to investments would be
 recognized in other expense. Equity method investments are carried
 at original cost and are included in other assets, net in the

 such as indirect labor, supplies, tools, repairs and depreciation
 costs. Much of the material associated with Quanta&#x2019;s work is
 owner-furnished and is therefore not included in contract revenues
 and costs. The cost estimation process is based on professional
 knowledge and experience of Quanta&#x2019;s engineers, project
 managers and financial professionals. Changes in job performance,
 job conditions and final contract settlements are factors that
 influence management&#x2019;s assessment of total contract value and
 the total estimated costs to complete those contracts and
 therefore, Quanta&#x2019;s profit recognition.</p>

 sometimes substantially, from previous estimates due to changes in
 a variety of factors including unforeseen circumstances not
 included in Quanta&#x2019;s cost estimates or covered by its
 contracts for which it cannot obtain adequate compensation,
 including concealed or unknown environmental conditions; changes in
 the cost of equipment, commodities, materials or labor;
 unanticipated costs or claims due to customer-caused delays,
 customer failure to provide required materials or equipment, errors
 in engineering, specifications or designs, project modifications,
 or contract termination and Quanta&#x2019;s inability to obtain
 reimbursement for such costs or recover on such claims; weather
 conditions; and quality issues requiring rework or replacement.
 These factors, along with other risks inherent in performing fixed
 price contracts may cause actual revenues and gross profits for a
 project to differ from previous estimates and could result in
 reduced profitability or losses on projects. 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. These factors are routinely evaluated on a project by
 project basis throughout the project term, and the impact of
 corresponding revisions in management&#x2019;s estimates of contract
 value, contract cost and contract profit are recorded as necessary
 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.</p>

 2016.&#xA0;Included within the operating results for the three

 project of $16.5 million. Quanta is in the process of developing
 potential claims; however, no revenues or cost recovery has been
 reflected in Quanta&#x2019;s estimate of total project losses at
 March&#xA0;31, 2017. At March&#xA0;31, 2017, this project was
 approximately 85% complete. As this project continues, it is
 possible that additional delays or other unforeseen circumstances

 for income taxes. Under this method, deferred tax assets and

 differences between the financial reporting and tax bases of assets
 and liabilities and are measured using the enacted tax rates and

 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.</p>

 certain tax positions in those instances where Quanta considers it
 more likely than not that additional taxes may be due in excess of

 reserves for expected tax consequences of uncertain positions,
 Quanta assumes that taxing authorities have full knowledge of the
 position and all relevant facts. Quanta continually reviews
 exposure to additional tax obligations, and as further information
 is known or events occur, changes in tax reserves may be recorded.
 To the extent interest and penalties may be assessed by taxing

 primarily from tax positions to be taken for 2017. Although the
 Internal Revenue Service completed its examination related to tax
 years 2010, 2011 and 2012 during the year ended December&#xA0;31,
 2016, certain subsidiaries remain under examination by various U.S.
 state, Canadian and other foreign tax authorities for multiple

 The resulting compensation expense from time-based RSU and

 identifiable intangible assets acquired typically include goodwill,
 backlog, customer relationships, trade names, covenants

 utilizes the fair value premise as the primary basis for its
 valuation procedures, which is a market-based approach to determine
 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, including 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. In accordance with its annual impairment test during the
 quarter ended December&#xA0;31, 2016, the carrying amounts of such
 assets, including goodwill, were compared to their fair values. The
 level of inputs used for these fair value measurements is the
 lowest level (Level 3). Quanta uses the assistance of third party
 specialists to develop valuation assumptions. Quanta believes that
 these valuation methods appropriately represent the methods that
 would be used by other market participants in determining fair
 value.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify">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 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 nonrecurring 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

 requires inventory to be measured at the lower of either cost or
 net realizable value. When evidence exists that the net realizable
 value of inventory is lower than its cost, the difference will be
 recognized as a loss in earnings in the period in which it occurs.
 Quanta adopted this guidance effective January&#xA0;1, 2017, and
 the adoption of the update did not have a significant impact on
 Quanta&#x2019;s consolidated financial statements or related
 disclosures.</p>

 amends the accounting for share-based payments in several key
 areas, including the treatment and cash flow presentation of tax
 effects related to the settlement of share-based payments and the
 accounting for forfeitures of share-based awards. The new guidance
 requires companies with share-based payments to record all tax
 effects related thereto at settlement (or expiration) through
 income tax expense on the statement of operations rather than
 through additional paid-in capital (APIC) within equity. This
 update also requires excess tax benefits to be classified as an
 operating activity on the statement of cash flows rather than
 reclassified as a financing activity and requires cash paid by an
 employer when withholding shares for taxes to be presented as a
 financing activity. The update also allows companies to either
 account for forfeitures of share-based payments as they occur or to
 estimate forfeitures. This guidance is required to be applied
 prospectively except for the requirement to classify cash paid when
 withholding shares for the employee portion of taxes as a financing
 activity, which requires retrospective application. Quanta adopted
 this guidance effective January&#xA0;1, 2017 and will continue to
 estimate forfeitures of share-based payments. Quanta anticipates
 increased volatility of income tax expense after adoption of this
 guidance, and during the three months ended March&#xA0;31, 2017
 recorded an income tax benefit of $4.9 million related to the
 settlement of share-based awards. APIC was not adjusted for amounts
 recorded prior to 2017, and therefore Quanta&#x2019;s retained
 earnings were not affected by the adoption of this guidance as of
 January&#xA0;1, 2017. Additionally, $6.1 million was reclassified
 from an operating activity to a financing activity on the statement
 of cash flows for the three months ended March&#xA0;31, 2016
 associated with cash paid by Quanta to satisfy tax withholding
 obligations for share-settled awards.</p>

 amends the consolidation guidance related to how a reporting entity
 that is the single decision maker of a VIE should treat indirect
 interests in the VIE held through related parties that are under
 common control with the reporting entity when determining whether
 it is the primary beneficiary of a VIE. A reporting entity has an
 indirect interest in a VIE if it has a direct interest in a related
 party that, in turn, has a direct interest in the VIE. Quanta
 adopted this guidance on January&#xA0;1, 2017, and the adoption of
 the update did not have a significant impact on its consolidated
 financial statements or related disclosures.</p>

 supersedes most current revenue recognition guidance, as well as
 some cost recognition guidance. The update requires that the
 recognition of revenue related to the transfer of goods or services
 to customers reflects the consideration to which the entity expects
 to be entitled in exchange for those goods or services. This update
 also requires new qualitative and quantitative disclosures about
 the nature, amount, timing and uncertainty of revenues and cash
 flows arising from customer contracts, including significant
 judgments and changes in judgments, information about contract
 balances and performance obligations, and assets recognized from
 costs incurred to obtain or fulfill a contract. In July 2015, the
 FASB affirmed its proposal to defer the effective date until fiscal
 years beginning on or after December&#xA0;15, 2017. The guidance
 can be applied on a full retrospective or modified retrospective
 basis whereby the entity records a cumulative effect of initially
 applying this update at the date of initial application.</p>

 of this update on its consolidated financial statements. Quanta
 currently anticipates adopting the update using the modified
 retrospective transition method, which may result in a
 cumulative-effect adjustment recorded in retained earnings as of
 the beginning of the period of adoption. In addition, Quanta
 continues to monitor activity related to the new standard as well
 as working with various non-authoritative groups regarding industry
 clarifications and interpretations, which may impact Quanta&#x2019;s
 considerations and conclusions. While Quanta is still evaluating
 the requirements of this update, it currently does not expect the
 update to materially affect its results of operations, financial
 position or cash flows. This preliminary conclusion is based on
 Quanta&#x2019;s belief that it will generally continue to recognize
 revenues from long-term service contracts over time as services are
 performed and the underlying obligation to the customer is
 fulfilled. Quanta has identified and is in the process of
 implementing changes to its processes and internal controls to meet
 the reporting and disclosure requirements of this update and will
 adopt this update effective January&#xA0;1, 2018.</p>

 change the way companies measure credit losses for most financial
 assets and certain other instruments that are not measured at fair
 value through net income. The update will require companies to use
 an &#x201C;expected loss&#x201D; model for instruments measured at
 amortized cost and to record allowances for available-for-sale
 (AFS) debt securities rather than reduce the carrying amounts. The
 update will also require disclosure of information regarding how a
 company developed its allowance, including changes in the factors
 that influenced management&#x2019;s estimate of expected credit
 losses and the reasons for those changes. Companies will apply this
 standard&#x2019;s provisions as a cumulative-effect adjustment to

 will require a reporting entity to recognize the tax expense from
 the sale of an asset in the seller&#x2019;s tax jurisdiction when
 the transfer occurs, even though the pre-tax effects of that
 transaction are eliminated in consolidation. Any deferred tax asset
 that arises in the buyer&#x2019;s jurisdiction would also be
 recognized at the time of the transfer. The new guidance will not
 apply to intra-entity transfers of inventory. The income tax
 consequences from the sale of inventory from one member of a
 consolidated entity to another will continue to be deferred until
 the inventory is sold to a third party. The new standard is
 effective for interim and annual reporting periods beginning after

 to clarify the definition of a business to assist entities with
 evaluation of whether transactions should be accounted for as
 acquisitions or disposals of assets or businesses. The new
 definition requires that when substantially all of the fair value
 of the gross assets acquired or disposed of is concentrated in a
 single identifiable asset or group of similar identifiable assets,
 the asset or group is not a business. The update will require that
 to be considered a business, a set of assets and activities must
 include, at a minimum, an input and a substantive process that
 together significantly contribute to the ability to create output.
 Additionally, the update will remove the evaluation of whether a
 market participant could replace missing elements in order to
 consider the set of assets and activities a business, will provide
 more stringent criteria for sets without outputs and will narrow
 the definition of output. The new standard is effective for interim
 and annual reporting periods beginning after December&#xA0;15,
 2017, although early adoption is permitted for certain
 transactions. The prospective transition method will be required
 for this new guidance. Quanta is currently evaluating the potential

 intended to simplify the subsequent measurement of goodwill by
 eliminating the second step in the current two-step goodwill
 impairment test. The update will require an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity will
 recognize an impairment charge for the amount by which the carrying
 amount exceeds the reporting unit&#x2019;s fair value, if
 applicable. Additionally, the update will eliminate the requirement
 that a reporting unit with a zero or negative carrying amount
 perform a qualitative assessment and the second step of the
 two-step goodwill impairment test and will instead require
 disclosure of the amount of goodwill allocated to each reporting
 unit with a zero or negative carrying amount of net assets. This
 update is effective for public entities for interim and annual
 reporting periods beginning after December&#xA0;15, 2019, although
 early adoption is permitted for interim and annual goodwill
 impairment tests performed on testing dates after January&#xA0;1,
 2017. The prospective transition method will be required for this
 new guidance. Quanta is currently evaluating the potential impact
 of this authoritative guidance on its consolidated financial

 million to JPMorgan Chase Bank, National Association, London Branch
 (JPMorgan) and initially received 25.7&#xA0;million shares of its
 common stock. The fair market value of these 25.7&#xA0;million
 shares at the time of delivery was $600.0 million, and the
 repurchased shares and the related cost to acquire them were
 accounted for as an adjustment to the balance of treasury stock
 during the third quarter of 2015, reducing the weighted-average
 number of basic and diluted common shares used to calculate
 Quanta&#x2019;s earnings per share. The $150.0 million remaining
 under the ASR was recorded as an adjustment to APIC during the

 final settlement and based on the final volume-weighted average
 share price during the term of the ASR, minus a discount and
 subject to other adjustments pursuant to the terms and conditions

 54.3&#xA0;million shares of its common stock at a cost of $1.20
 billion under the 2015 Repurchase Program. No common stock was
 repurchased in the three months ended March&#xA0;31, 2017 or 2016
