 &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 realized 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. The cash flows resulting from the tax deductions in
 excess of the compensation expense recognized for restricted stock,
 RSUs and performance units to be settled in common stock and stock
 options (excess tax benefit) 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, RSUs and
 performance unit awards, see Note 10.&lt;/p&gt;

 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;

 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; LINE-HEIGHT: 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; LINE-HEIGHT: 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 revenue growth rates, operating
 margins, discount rates, weighted average costs of capital and
 future market conditions, among others. Quanta believes the
 estimates and assumptions used in its impairment assessments are
 reasonable and based on available market information, but
 variations in any of the assumptions could result in materially
 different calculations of fair value and determinations of whether
 or not an impairment is indicated.&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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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;

 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; LINE-HEIGHT: 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 2015, 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
 two other reporting units described below, was substantially in
 excess of its carrying value. After performing step two of the
 analysis, management concluded that goodwill was impaired at two
 reporting units in Quanta&amp;#x2019;s Oil and Gas Infrastructure
 Services Division. Accordingly, during the fourth quarter of 2015,
 Quanta recorded a $39.8 million non-cash charge for the impairment
 of goodwill which primarily resulted from lower forecasted oil and
 gas services revenues for its Gulf of Mexico operations and certain
 operations in Australia, due to the extended low commodity price
 environment.&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; LINE-HEIGHT: 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
 2015 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
 giving consideration to a 10% decrease in the fair value of each of
 Quanta&amp;#x2019;s reporting units, the results of the assessment at
 December&amp;#xA0;31, 2015 did not change. However, 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; LINE-HEIGHT: 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, the decline in oil prices which has negatively impacted
 customer spending, project delays and constrained customer capital
 spending as a result of an increasingly complex regulatory and
 permitting environment. Certain operating units within our Oil and
 Gas Infrastructure Services segment that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors.&amp;#xA0;While no interim
 impairment charges were recorded during the six months ended June
 30, 2016, Quanta will continue to monitor 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.&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; LINE-HEIGHT: 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;

 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;

 an impairment charge of $12.1 million related to customer
 relationships, trade names and non-compete agreement intangible
 assets. These intangible asset impairments primarily resulted from
 lower forecasted oil and gas services revenues for Quanta&amp;#x2019;s
 Gulf of Mexico operations and certain operations in Australia, due
 to the extended low commodity price environment. The two reporting
 units impacted also had related goodwill impairments, as discussed
 above, and are in Quanta&amp;#x2019;s Oil and Gas Infrastructure
 Services Division.&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;On December&amp;#xA0;18, 2015, Quanta entered into an
 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;
 &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 June&amp;#xA0;30, 2016, Quanta had approximately
 $317.3 million of outstanding letters of credit and bank
 guarantees, $217.6 million of which were denominated in U.S.
 dollars and $99.7 million of which were denominated in Australian
 or Canadian dollars. Quanta also had $398.0 million of outstanding
 revolving loans under the credit facility, $300.0 million of which
 were denominated in U.S. dollars and $98.0 million of which were
 denominated in Canadian dollars. The remaining $1.09 billion was
 available for revolving loans or issuing new letters of credit or
 bank guarantees. Information on borrowings under Quanta&amp;#x2019;s

 &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 current credit agreement, amounts
 borrowed in U.S. dollars bear interest, at Quanta&amp;#x2019;s option,
 at a rate equal to either (i) the Eurocurrency Rate (as defined in
 the credit agreement) plus 1.125% to 2.125%, as determined based on
 Quanta&amp;#x2019;s Consolidated Leverage Ratio (as described below), or
 (ii) 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The Consolidated Leverage Ratio is the ratio of
 Quanta&amp;#x2019;s Consolidated Funded Indebtedness to Consolidated
 EBITDA (as those terms are defined in the credit agreement). For
 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) the Federal
 Funds Rate (as defined in the credit agreement) plus 0.5%, (ii) the
 prime rate publicly announced by Bank of America, N.A. and (iii)
 the Eurocurrency Rate plus 1.00%.&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;Subject to certain exceptions, the credit agreement
 is secured by substantially all the assets of Quanta and
 Quanta&amp;#x2019;s wholly owned U.S. subsidiaries and by a pledge of
 all of the capital stock of Quanta&amp;#x2019;s wholly owned U.S.
 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) a corporate credit rating that is
 BBB- or higher by Standard &amp;amp; Poor&amp;#x2019;s Rating Services, (ii)
 a corporate family rating that is Baa3 or higher by Moody&amp;#x2019;s
 Investors Services, Inc. or (iii) a corporate credit rating that is
 BBB- or higher by Fitch Ratings, Inc.).&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 credit 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 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) no default or event of
 default under the credit agreement; (ii) continued compliance with
 the financial covenants in the credit agreement; and (iii) at least
 $100.0 million of availability under the credit agreement and/or
 cash and cash equivalents on hand. As of June&amp;#xA0;30, 2016, Quanta
 was in compliance with all of the covenants in the credit
 agreement.&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 credit agreement provides for customary events
 of default and contains cross-default provisions with
 Quanta&amp;#x2019;s underwriting, continuing indemnity and security
 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;

 &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 $162.3
 million and $128.8 million as of June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015. 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 June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015, cash equivalents were $5.7 million and
 $1.4 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 June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015, cash and cash equivalents held in domestic
 bank accounts were approximately $13.4 million and $16.1 million,
 and cash and cash equivalents held in foreign bank accounts were
 approximately $148.9 million and $112.7 million. As of
 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, cash and cash
 equivalents held by Quanta&amp;#x2019;s investments in joint ventures,
 which are either consolidated or proportionately consolidated, were
 approximately $17.8 million and $24.9 million, of which $13.4
 million and $11.9 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, and Quanta
 does not have access to that cash for its other operations. Under
 the terms of the partnership agreements, Quanta generally has no
 right to the joint ventures&amp;#x2019; cash 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-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;On May&amp;#xA0;19, 2011, Quanta&amp;#x2019;s stockholders
 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 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Additionally, pursuant to the Quanta Services, Inc.
 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. 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The 2011 Plan, the 2007 Plan and the RSU Plan,

 &lt;b&gt;&lt;i&gt;Restricted Stock and RSUs to be Settled in Common
 Stock&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;During each of the three months ended June&amp;#xA0;30,
 2016 and 2015, Quanta granted 0.1 million of RSUs to be settled in
 common stock under the Plans with weighted average grant date fair
 values of $23.59 and $29.96. During the six months ended
 June&amp;#xA0;30, 2016 and 2015, Quanta granted 1.8 million and 1.2
 million of RSUs to be settled in common stock under the Plans with
 weighted average grant date fair values of $22.11 and $27.90. 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;During each of the three months ended June&amp;#xA0;30,
 2016 and 2015, vesting activity consisted of&amp;#xA0;0.1 million of
 shares of restricted stock and RSUs settled in common stock with an
 approximate fair value at the time of vesting of $1.1 million and
 $2.3 million. During the six months ended June&amp;#xA0;30, 2016 and
 2015, vesting activity consisted of&amp;#xA0;1.3 million and 1.1
 million of shares of restricted stock and RSUs settled in common
 stock with an approximate fair value at the time of vesting of
 $26.4 million and $33.8 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;During the three months ended June&amp;#xA0;30, 2016
 and 2015, Quanta recognized $8.5 million and $9.0 million on
 non-cash stock compensation expense related to restricted stock and
 RSUs to be settled in common stock. During the six months ended
 June&amp;#xA0;30, 2016 and 2015, Quanta recognized $21.7 million and
 $17.8 million in non-cash stock compensation expense related to
 restricted stock and RSUs to be settled in common stock. As of
 June&amp;#xA0;30, 2016, there was approximately $44.0 million of total
 unrecognized compensation cost related to unvested restricted stock
 and RSUs to be settled in common stock granted to both employees
 and non-employees. This cost is expected to be recognized over a
 weighted average period of 1.97&amp;#xA0;years.&lt;/p&gt;

 provide for the issuance of shares of common stock upon vesting.
 These performance units cliff-vest at the end of a three-year
 performance period based on achievement of three-year company
 financial performance targets and strategic initiatives established
 by the Compensation Committee. The final amount of earned and
 vested performance units can range from 0% to 200% of the initial
 amount awarded based on the level of achievement of performance
 goals, as determined by the Compensation Committee.&lt;/p&gt;

 and 2015, Quanta granted 0.1 million and no performance units to be
 settled in common stock under the 2011 Plan, with a weighted
 average grant date fair value of $24.11 for the performance units
 granted during the three months ended June&amp;#xA0;30, 2016. During
 the six months ended June&amp;#xA0;30, 2016 and 2015, Quanta granted
 0.3 million and 0.2 million performance units to be settled in
 common stock under the 2011 Plan, with a weighted average grant
 date fair value of $22.86 and $28.16. The grant date fair value for
 awards of performance units to be settled in common stock is based
 on the market value of Quanta common stock on the date of grant
 applied to the total number of shares that Quanta anticipates will
 fully vest.&amp;#xA0;This fair value is expensed ratably over the
 vesting term and is adjusted for fair value changes, so that the
 expense recognized for each award is equivalent to the fair value
 of the final number of earned and vested performance
 units.&amp;#xA0;During the three months ended June&amp;#xA0;30, 2016 and
 2015, Quanta recognized $1.0 million and $0.7 million in
 compensation expense associated with performance units to be
 settled in common stock.&amp;#xA0;During the six months ended
 June&amp;#xA0;30, 2016 and 2015, Quanta recognized $1.5 million and
 $1.4 million in compensation expense associated with performance
 units to be settled in common stock.&amp;#xA0;No performance units
 vested, and no shares of common stock were issued in connection
 with performance units, during the three and six months ended
 June&amp;#xA0;30, 2016 and 2015, as applicable performance periods had
 not yet concluded.&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 RSUs granted by Quanta under the Plans are
 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 on the settlement date of one share

 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

 statements have been prepared pursuant to the rules of the
 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

 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
 operations, comprehensive income and cash flows with respect to the

 included. The results of operations and comprehensive income for
 the interim periods are not necessarily indicative of the results

 &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;

 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;

 Quanta, typically each joint venturer 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
 joint venturer 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;

 turnkey EPC services for the entire project. As of June&amp;#xA0;30,

 unconsolidated affiliate of $8.4 million and had received $2.3

 purchase these vehicles at the time of their delivery, Quanta

 leasing companies and made available to Quanta under certain of its

 its capital commitments.&lt;/p&gt;

 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;

Telecom Network Specialists,
 Inc., et al.&lt;/i&gt;&lt;i&gt;&amp;#xA0;&lt;/i&gt;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;Benton seeks to represent a class of workers that
 includes all persons who worked on TNS projects between June 2002
 and the present, including individuals that TNS retained through 29
 staffing agencies.&amp;#xA0;An amended complaint was filed in August
 2007, naming two additional class representatives, one of whom has
 since settled directly with his employer.&amp;#xA0;The
 plaintiffs&amp;#x2019; motion for class certification was heard and
 denied in May 2012; however, that decision was appealed, and the
 case was ultimately remanded for reconsideration. In September
 2015, after a hearing in the remanded proceeding, the trial court
 certified the class as to workers from the various staffing
 companies at issue. The plaintiffs seek approximately $16 million
 for class damages and $5 million in attorneys&amp;#x2019;
 fees.&amp;#xA0;Quanta retained liability associated with this matter
 pursuant to the terms of Quanta&amp;#x2019;s sale of TNS in December
 2012.&lt;/p&gt;

 complaints for indemnity 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.&amp;#xA0;TNS appealed the
 court&amp;#x2019;s ruling, and in April 2015, the California Appellate
 Court reversed the trial court&amp;#x2019;s decision, vacated its award
 of attorneys&amp;#x2019; fees, and instructed the trial court to
 reconsider its earlier ruling on TNS&amp;#x2019;s indemnity
 claims.&amp;#xA0;At this time, Quanta does not believe this matter will
 have a material adverse effect on its consolidated financial
 position, results of operations or cash flows.&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: &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: 6pt; LETTER-SPACING: normal; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;Quanta is subject to concentrations of credit risk
 related primarily to its cash and cash equivalents and accounts
 receivable, including amounts related to unbilled accounts
 receivable and costs and estimated earnings in excess of billings
 on uncompleted contracts. Substantially all of Quanta&amp;#x2019;s cash
 investments 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
 this cash in a diversified portfolio of what Quanta believes to be
 high quality investments, which consist primarily of
 interest-bearing demand deposits, money market 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 investments 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;

 one customer accounted for approximately 18% and 12% of
 Quanta&amp;#x2019;s consolidated net position. The services provided to
 this customer related primarily to Quanta&amp;#x2019;s Electric Power
 Infrastructure Services segment. No customers represented 10% or
 more of Quanta&amp;#x2019;s revenues for the three and six months ended
 June&amp;#xA0;30, 2016 and 2015, and no other customers represented 10%
 or more of Quanta&amp;#x2019;s consolidated net position as of
 June&amp;#xA0;30, 2016 or December&amp;#xA0;31, 2015.&lt;/p&gt;

 employer&amp;#x2019;s liability, group health, general liability, auto
 liability and workers&amp;#x2019; compensation claims. As of
 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, the gross amount
 accrued for insurance claims totaled $212.9 million and $209.0
 million with $158.2 million and $153.5 million considered to be
 long-term and included in other non-current liabilities. Related
 insurance recoveries/receivables as of June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015 were $9.2 million and $8.6 million, of which
 $0.6 million and $0.6 million were included in prepaid expenses and
 other current assets and $8.6 million and $8.0 million were
 included in other assets, net.&lt;/p&gt;

 of credit to ensure reimbursement for amounts they are disbursing
 on its 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 its 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;

 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 2016 and 2017. 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;

 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 June&amp;#xA0;30, 2016, the total amount of
 the outstanding performance bonds was estimated to be approximately
 $2.7 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 $667 million as of June&amp;#xA0;30,
 2016.&lt;/p&gt;

 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
 under any of these guarantees.&lt;/p&gt;

 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 of control of
 Quanta. Quanta may be obligated to pay certain amounts to such
 employees upon the occurrence of any of the defined events in the
 various employment agreements.&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; MARGIN-LEFT: 34px; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 18pt; LETTER-SPACING: normal; LINE-HEIGHT: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal"&gt;
 &lt;b&gt;&lt;i&gt;Collective Bargaining Agreements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;&lt;i&gt;2011 Central States Plan Withdrawal
 Liability.&lt;/i&gt;&amp;#xA0;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 30, 2012 for all Quanta subsidiaries.&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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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 partial withdrawal liability in the amount of $32.9
 million.&lt;/p&gt;

 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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 June&amp;#xA0;30, 2016.
 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 June&amp;#xA0;30, 2016,
 Quanta had made payments totaling $13.7 million toward the
 withdrawal liability assessment.&lt;/p&gt;

 Liability.&lt;/i&gt;&amp;#xA0;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 approximately $2.1 million 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 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 June&amp;#xA0;30, 2016, payments totaling $3.1 million had been
 made toward the withdrawal liability assessment.&lt;/p&gt;

 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;

 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
 June&amp;#xA0;30, 2016, except as otherwise set forth above
 in&amp;#xA0;&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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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 June&amp;#xA0;30, 2016, Quanta 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 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, 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 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, 2015, 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

 December&amp;#xA0;31, 2015, Quanta had allowances for doubtful accounts
 on current receivables of approximately $2.7 million and $5.2
 million. Long-term accounts receivable are included within other
 assets, net on the consolidated balance sheets.&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: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; 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 June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015 were approximately $221.0 million and
 $250.1 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 June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015 were $4.4 million and $4.5 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 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, the balances of
 unbilled receivables included in accounts receivable were
 approximately $228.0 million and $233.6 million.&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 February 2015, the FASB issued an update which
 amends existing consolidation guidance, including amending the
 guidance related to determining whether an entity is a variable
 interest entity. The guidance may be applied using a modified
 retrospective approach whereby the entity records a cumulative
 effect of adoption at the beginning of the fiscal year of initial
 application. A reporting entity may also apply the amendments on a
 full retrospective basis. Quanta adopted this guidance effective
 January&amp;#xA0;1, 2016, 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: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In April 2015, the FASB issued an update that
 requires debt issuance costs related to a recognized debt liability
 to be presented in the balance sheet as a direct deduction from the
 carrying amount of that debt liability, consistent with the
 presentation of debt discounts and premiums. The update is required
 to be adopted retroactively for all periods presented. In August
 2015, the FASB issued another update that states that the
 Securities Exchange Commission (SEC) staff would not object to an
 entity deferring and presenting debt issuance costs as an asset and
 subsequently amortizing the deferred debt issuance costs ratably
 over the term of the line-of-credit arrangement, regardless of
 whether there are any outstanding borrowings on the line-of-credit
 arrangement. Quanta adopted this guidance effective January&amp;#xA0;1,
 2016, 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: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In April 2015, the FASB issued an update that
 provides guidance to customers about whether a cloud computing
 arrangement includes a software license. If a cloud computing
 arrangement includes a software license, then the customer should
 account for the software license element of the arrangement
 consistent with the acquisition of other software licenses. If a
 cloud computing arrangement does not include a software license,
 the customer should account for the arrangement as a service
 contract. An entity can elect to adopt the amendments either
 prospectively to all arrangements entered into or materially
 modified after the effective date or retrospectively. Quanta
 adopted this guidance effective January&amp;#xA0;1, 2016, 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: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;In September 2015, the FASB issued an update that
 requires an acquiring company to recognize adjustments to
 provisional amounts that are identified during the measurement
 period in the reporting period in which such adjustments are
 determined. An acquiring company must record any effect on earnings
 from changes in depreciation or amortization or other income
 effects, calculated as if the accounting had been completed at the
 acquisition date. The acquiring company must also present
 separately on the face of the income statement or disclose in the
 notes the amount recorded in current-period earnings that would
 have been recorded in previous reporting periods if the adjustment
 had been recognized as of the acquisition date. The update is
 required to be adopted prospectively to adjustments that occur
 after the effective date with earlier application permitted for
 financial statements that have not yet been issued. Quanta adopted
 this guidance effective January&amp;#xA0;1, 2016, 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: Times New Roman; MARGIN-LEFT: 2%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Accounting Standards Not Yet Adopted&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 May 2014, the FASB issued an update that
 supersedes most current revenue recognition guidance as well as
 some cost recognition guidance. The update requires that an entity
 recognize revenue to depict the transfer of goods or services to
 customers in an amount that 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&amp;#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. Quanta is currently evaluating the
 potential impact of this authoritative guidance on its consolidated
 financial statements and will adopt this guidance effective
 January&amp;#xA0;1, 2018.&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 August 2014, the FASB issued guidance to address
 the diversity in practice in determining when there is substantial
 doubt about an entity&amp;#x2019;s ability to continue as a going
 concern and when and how an entity must disclose certain relevant
 conditions and events. This update requires an entity to evaluate
 whether there are conditions or events, considered in the
 aggregate, that raise substantial doubt about the entity&amp;#x2019;s
 ability to continue as a going concern for a period of one year
 after the date that the financial statements are issued (or
 available to be issued). If such conditions or events exist, an
 entity should disclose that there is substantial doubt about the
 entity&amp;#x2019;s ability to continue as a going concern for a period
 of one year after the date that the financial statements are issued
 (or available to be issued), along with the principal conditions or
 events that raise substantial doubt, management&amp;#x2019;s evaluation
 of the significance of those conditions or events in relation to
 the entity&amp;#x2019;s ability to meet its obligations and
 management&amp;#x2019;s plans that are intended to mitigate those
 conditions or events. The guidance is effective for annual and
 interim periods ending after December&amp;#xA0;15, 2016. This guidance
 will impact the disclosure and presentation of any substantial
 doubt by Quanta about its ability to continue as a going concern,
 if such substantial doubt were to exist. Quanta will adopt this
 guidance by 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;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.
 The update is required to be adopted prospectively and is effective
 for interim and annual reporting periods beginning after
 December&amp;#xA0;15, 2016, although early adoption is permitted.
 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, 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;In January 2016, the FASB issued an update that
 addresses certain aspects of recognition, measurement,
 presentation, and disclosure of financial instruments. The new
 standard is effective for interim and annual periods beginning
 after December&amp;#xA0;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&amp;#xA0;1, 2018.&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 February 2016, the FASB issued an update that
 requires companies that lease assets to recognize on the balance
 sheet the assets and liabilities for the rights and obligations
 created by those assets. The new standard is effective for interim
 and annual periods beginning after December&amp;#xA0;15, 2018. 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&amp;#xA0;1, 2019.&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 March 2016, the FASB issued an update that
 requires companies with share-based payments to record all of the
 tax effects related to such share-based payments at settlement (or
 expiration) through the income statement rather than through
 equity. It is anticipated that companies will experience increased
 volatility of income tax expense upon adoption of this update. This
 change is required to be applied prospectively to all excess tax
 benefits and tax deficiencies resulting from settlements after the
 date of the adoption of the update and is effective for interim and
 annual reporting periods beginning after December&amp;#xA0;15, 2016,
 although early adoption is permitted. 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, 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;In June 2016, the FASB issued an update that will
 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
 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;

 provides guidance to customers about whether a cloud computing
 arrangement includes a software license. If a cloud computing
 arrangement includes a software license, then the customer should
 account for the software license element of the arrangement
 consistent with the acquisition of other software licenses. If a
 cloud computing arrangement does not include a software license,
 the customer should account for the arrangement as a service
 contract. An entity can elect to adopt the amendments either
 prospectively to all arrangements entered into or materially
 modified after the effective date or retrospectively. Quanta
 adopted this guidance effective January&amp;#xA0;1, 2016, 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-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman" align="justify"&gt;In September 2015, the FASB issued an update that
 requires an acquiring company to recognize adjustments to
 provisional amounts that are identified during the measurement
 period in the reporting period in which such adjustments are
 determined. An acquiring company must record any effect on earnings
 from changes in depreciation or amortization or other income
 effects, calculated as if the accounting had been completed at the
 acquisition date. The acquiring company must also present
 separately on the face of the income statement or disclose in the
 notes the amount recorded in current-period earnings that would
 have been recorded in previous reporting periods if the adjustment
 had been recognized as of the acquisition date. The update is
 required to be adopted prospectively to adjustments that occur
 after the effective date with earlier application permitted for
 financial statements that have not yet been issued. Quanta adopted
 this guidance effective January&amp;#xA0;1, 2016, 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;

 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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: &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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" 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 are classified in the provision for income
 taxes.&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; LINE-HEIGHT: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal" align="justify"&gt;As of June&amp;#xA0;30, 2016, the total amount of
 unrecognized tax benefits relating to uncertain tax positions was
 $57.9 million, an increase from December&amp;#xA0;31, 2015 of $3.4
 million. This increase in unrecognized tax benefits resulted
 primarily from a $1.9 million increase due to tax positions
 expected to be taken for 2016 and a $1.9 million increase due to
 tax positions of an acquired company taken in periods prior to the
 acquisition. Quanta is currently under examination by the Internal
 Revenue Service (IRS) for tax years 2010, 2011 and 2012, and the
 federal statute of limitations for examination of all subsequent
 years remains open. Additionally, certain subsidiaries are 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 $25.9 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;

 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;

 three acquisitions. The results of two of the acquired companies
 are generally included in Quanta&amp;#x2019;s Electric Power
 Infrastructure Services segment. These companies included 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. The aggregate consideration for these
 acquisitions consisted of approximately $42.2 million paid or
 payable in cash, subject to certain adjustments, and contingent
 consideration payments of up to $35 million, which will be paid if
 certain financial targets are achieved. Based on the estimated fair
 value of this contingent consideration, Quanta recorded a $15.4
 million liability. As these transactions were effective during the
 first quarter of 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 and Canada.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;2015 Acquisitions&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

The
 results of eight of the acquired companies are generally included
 in Quanta&amp;#x2019;s Electric Power Infrastructure Services segment.
 These companies include a foundation services company located in
 the United States, an electrical contracting company located in the
 United States, an electrical engineering company located in
 Australia, a powerline construction company located in the United
 States, an engineering company located in Canada, an engineering,
 procurement and construction services company based in the United
 States, an underground construction contracting company located in
 Canada, and a supplier and material procurement specialist for the
 power and utility industry in Canada. The results of the remaining
 three acquired companies are generally included in Quanta&amp;#x2019;s
 Oil and Gas Infrastructure Services segment. These companies
 include a company that services above-ground storage tanks in the
 United States, an underground utility distribution contractor that
 provides services to gas and electric utilities in Canada, and a
 company that specializes in the engineering, procurement,
 construction, and commissioning of compression and surface
 facilities for the high pressure gas industry in Australia. The
 aggregate consideration for these acquisitions consisted of
 approximately $110.4 million paid or payable in cash, subject to
 net working capital adjustments, 461,037 shares of Quanta common
 stock valued on the settlement dates of the acquisitions at
 approximately $10.1 million, and $1.0 million in contingent
 consideration. As these transactions were effective during 2015,
 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 electric power and oil and gas infrastructure service
 offerings in the United States, Canada and Australia.&lt;/p&gt;

 assessments of the fair values of the acquired assets and assumed
 liabilities related to businesses acquired subsequent to
 June&amp;#xA0;30, 2015, 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 respective acquisition dates with possible updates
 primarily related to certain tax estimates. The aggregate purchase
 consideration related to the businesses acquired in 2015 subsequent
 to June&amp;#xA0;30, 2015 was preliminarily allocated to acquired
 assets and assumed liabilities, which resulted in a preliminary
 allocation of approximately $19.4 million of net tangible assets,
 $26.4 million of goodwill and $10.2 million of other intangible
 assets. Additionally, the aggregate purchase consideration related
 to the first quarter 2016 acquisitions was preliminarily allocated
 to acquired assets and assumed liabilities, which resulted in a
 preliminary allocation of approximately $23.2 million of net
 tangible assets, $26.1 million of goodwill and $8.3 million of
 other intangible assets.&lt;/p&gt;

 price over the net amount of the fair values assigned to assets
 acquired and liabilities assumed. The 2016 and 2015 acquisitions
 strategically expanded Quanta&amp;#x2019;s Canadian, Australian and
 domestic electric power and oil and gas service offerings, which
 Quanta believes contributes to the recognition of the goodwill. In
 connection with the 2016 acquisitions, goodwill of $5.8 million was
 recorded for the businesses acquired that were included within
 Quanta&amp;#x2019;s Electric Power Infrastructure Services Division and
 $20.3 million was recorded for the business acquired that was
 included within Quanta&amp;#x2019;s Oil and Gas Infrastructure Services
 Division on the dates of acquisition. In connection with the 2015
 acquisitions, goodwill of $31.2 million was recorded for the
 businesses acquired that were included within Quanta&amp;#x2019;s
 Electric Power Infrastructure Services Division and $20.4 million
 was recorded for businesses included within Quanta&amp;#x2019;s Oil and
 Gas Infrastructure Services Division on the dates of acquisition.
 Goodwill of approximately $0.4 million is expected to be deductible
 for income tax purposes related to the businesses acquired in the
 first six months of 2016, and goodwill of approximately $33.9
 million is expected to be deductible for income tax purposes
 related to the businesses acquired in 2015.&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 connection with certain Canadian acquisitions,
 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The holders of exchangeable shares associated with
 the Preferred Stock have rights equivalent to Quanta common
 stockholders with respect to voting, dividends and other economic
 rights. The holders of exchangeable shares not associated with the
 Preferred Stock have rights equivalent to Quanta common
 stockholders with respect to dividends and other economic rights
 but do not have voting rights.&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 June&amp;#xA0;30, 2016, both shares of the
 Preferred Stock remained outstanding and 6,876,042 exchangeable

 &lt;b&gt;&lt;i&gt;Treasury Stock&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;Under the stock incentive plans described in
 Note&amp;#xA0;10, the tax withholding obligations of employees upon
 vesting of restricted stock awards and RSUs settled in common stock
 are typically satisfied by Quanta making such tax payments and
 withholding a 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 352,061&amp;#xA0;and
 345,083 shares of Quanta common stock during the six months ended
 June&amp;#xA0;30, 2016 and 2015, with a total market value of $7.2
 million and $9.9 million. These shares and the related costs to
 acquire them were accounted for as adjustments to the balance of
 treasury stock. Under Delaware corporate law, treasury stock is not
 counted for quorum purposes or entitled to vote.&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 2013, Quanta&amp;#x2019;s
 board of directors approved a stock repurchase program authorizing
 Quanta to purchase, from time to time through December&amp;#xA0;31,
 2016, up to $500.0 million of its outstanding common stock (the
 2013 Repurchase Program). During the nine months ended September
 30, 2015, Quanta repurchased 14.3 million shares of its common
 stock at a cost of $406.5 million in the open market under the 2013
 Repurchase Program and completed the 2013 Repurchase Program.&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 third quarter of 2015, Quanta&amp;#x2019;s
 board of directors approved a new stock repurchase program
 authorizing Quanta to purchase, from time to time through February
 28, 2017, up to $1.25 billion of its outstanding common stock (the
 2015 Repurchase Program). Repurchases under the 2015 Repurchase
 Program can be made in open market or privately negotiated
 transactions, including pursuant to an accelerated share repurchase
 arrangement, an issuer repurchase plan or otherwise, at
 management&amp;#x2019;s discretion, based on market and business
 conditions, applicable contractual and legal requirements and other
 factors. The 2015 Repurchase Program does not obligate Quanta to
 acquire any specific amount of common stock and may be modified or
 terminated by Quanta&amp;#x2019;s board of directors at any time at its
 sole discretion and without notice. During the third and fourth
 quarters of 2015, Quanta repurchased 19.2 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Also during the third quarter of 2015, Quanta
 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 million shares of its common
 stock. The fair market value of these 25.7 million shares at the
 time of delivery was approximately $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 quarter ended September 30, 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 additional
 paid-in capital (APIC) during the quarter ended September 30, 2015
 and was reclassified from APIC to treasury stock on April&amp;#xA0;12,
 2016 as a result of the final settlement of the ASR. On
 April&amp;#xA0;12, 2016, upon final settlement of the ASR 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 million
 additional shares of its common stock from JPMorgan.&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 April&amp;#xA0;12, 2016, after final settlement
 of the ASR, Quanta had repurchased 54.3 million shares of its
 common stock at a cost of $1.20 billion under the 2015 Repurchase
 Program, and approximately $50.1 million remained available under
 the 2015 Repurchase Program.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Non-controlling Interests&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 holds investments in several joint ventures
 that provide infrastructure services under specific customer
 contracts. Quanta has determined that certain of these joint
 ventures are VIEs, with Quanta providing the majority of the
 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 $3.5
 million for the three months ended June&amp;#xA0;30, 2016 and 2015 and
 $0.5 million and $8.2 million for the six months ended
 June&amp;#xA0;30, 2016 and 2015 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: 12pt; TEXT-INDENT: 4%" align="justify"&gt;The carrying value of the investments held by
 Quanta in all of its VIEs was approximately $2.9 million and $2.3
 million at June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015. The
 carrying value of investments held by the non-controlling interests
 in these variable interest entities at June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015 was $2.9 million and $2.3 million. During
 the three months ended June&amp;#xA0;30, 2016 and 2015, distributions
 to non-controlling interests were none and $2.5 million. During the
 six months ended June&amp;#xA0;30, 2016 and 2015, distributions to
 non-controlling interests were none and $5.0 million. There were no
 other changes in equity as a result of transfers to/from the
 non-controlling interests during the six months ended June&amp;#xA0;30,
 2016 or 2015. See Note&amp;#xA0;11 for further disclosures related to

 conformity with US 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

 inventory, useful lives of assets, fair value assumptions in
 analyzing goodwill, other intangibles and long-lived asset
 impairments, equity and other investments, loan receivables,

 &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, joint trenching projects to install distribution lines for
 electric power and natural gas customers. 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;

 general liability, auto liability and workers&amp;#x2019; compensation
 claims. Under these programs, the deductibles for general liability
 and auto liability are $10.0 million per occurrence, the deductible
 for workers&amp;#x2019; compensation is $5.0 million per occurrence, and
 the deductible for employer&amp;#x2019;s liability is $1.0 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

 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;

 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;

 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

 conformity with US 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;Quanta had cash and cash equivalents of $162.3
 million and $128.8 million as of June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015. 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 June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015, cash equivalents were $5.7 million and
 $1.4 million, and consisted primarily of money market investments
 and money market mutual funds and are discussed further
 in&amp;#xA0;&lt;i&gt;Fair Value
 Measurements&lt;/i&gt;&amp;#xA0;below. As of June&amp;#xA0;30,
 2016 and December&amp;#xA0;31, 2015, cash and cash equivalents held in
 domestic bank accounts were approximately $13.4 million and $16.1
 million, and cash and cash equivalents held in foreign bank
 accounts were approximately $148.9 million and $112.7 million. As
 of June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, cash and cash
 equivalents held by Quanta&amp;#x2019;s investments in joint ventures,
 which are either consolidated or proportionately consolidated, were
 approximately $17.8 million and $24.9 million, of which $13.4
 million and $11.9 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, and Quanta
 does not have access to that cash for its other operations. Under
 the terms of the partnership agreements, Quanta generally has no
 right to the joint ventures&amp;#x2019; cash other than participating in
 distributions and in the event of dissolution.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 31px; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015, Quanta had allowances for doubtful accounts
 on current receivables of approximately $2.7 million and $5.2
 million. Long-term accounts receivable are included within other
 assets, net on the consolidated balance sheets.&lt;/p&gt;

 or file for bankruptcy, or should anticipated recoveries relating

 losses in excess of current allowances provided.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015 were approximately $221.0 million and
 $250.1 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 June&amp;#xA0;30, 2016 and
 December&amp;#xA0;31, 2015 were $4.4 million and $4.5 million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, the balances of
 unbilled receivables included in accounts receivable were
 approximately $228.0 million and $233.6 million.&lt;/p&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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 12pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 revenue growth rates, operating
 margins, discount rates, weighted average costs of capital and
 future market conditions, among others. Quanta believes the
 estimates and assumptions used in its impairment assessments are
 reasonable and based on available market information, but
 variations in any of the assumptions could result in materially
 different calculations of fair value and determinations of whether
 or not an impairment is indicated.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 12pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;During the fourth quarter of 2015, 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
 two other reporting units described below, was substantially in
 excess of its carrying value. After performing step two of the
 analysis, management concluded that goodwill was impaired at two
 reporting units in Quanta&amp;#x2019;s Oil and Gas Infrastructure
 Services Division. Accordingly, during the fourth quarter of 2015,
 Quanta recorded a $39.8 million non-cash charge for the impairment
 of goodwill which primarily resulted from lower forecasted oil and
 gas services revenues for its Gulf of Mexico operations and certain
 operations in Australia, due to the extended low commodity price
 environment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;As discussed generally above, when evaluating the
 2015 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
 giving consideration to a 10% decrease in the fair value of each of
 Quanta&amp;#x2019;s reporting units, the results of the assessment at
 December&amp;#xA0;31, 2015 did not change. However, 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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, the decline in oil prices which has negatively impacted
 customer spending, project delays and constrained customer capital
 spending as a result of an increasingly complex regulatory and
 permitting environment. Certain operating units within our Oil and
 Gas Infrastructure Services segment that primarily operate within
 the midstream and smaller-scale transmission market have continued
 to be negatively impacted by these factors.&amp;#xA0;While no interim
 impairment charges were recorded during the six months ended June
 30, 2016, Quanta will continue to monitor 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.&lt;/p&gt;

 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;

 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;

 an impairment charge of $12.1 million related to customer
 relationships, trade names and non-compete agreement intangible
 assets. These intangible asset impairments primarily resulted from
 lower forecasted oil and gas services revenues for Quanta&amp;#x2019;s
 Gulf of Mexico operations and certain operations in Australia, due
 to the extended low commodity price environment. The two reporting
 units impacted also had related goodwill impairments, as discussed
 above, and are in Quanta&amp;#x2019;s Oil and Gas Infrastructure
 Services Division.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Investments in Affiliates and Other Entities&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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
 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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;

 and Oil and Gas Infrastructure Services segments, Quanta designs,
 installs and maintains networks for customers in the electric power
 and oil and gas 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 our cost estimates or covered by our contracts for
 which we 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 our 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;During the six months ended June 30, 2016, Quanta
 experienced performance issues on an ongoing power plant project in
 Alaska that resulted in the revision of its estimate of total costs
 necessary to complete this project. During the first six months of
 2016 and as the project was planned to transition from final
 construction and testing to the commissioning phase, the project
 was negatively impacted by further third party engineering
 deficiencies that caused changes to Quanta&amp;#x2019;s planned scope of
 work and by performance failures by other contractors operating
 onsite. These issues resulted in higher than expected production
 costs and a related impact on production sequencing. In addition to
 these items, late in the second quarter of 2016 Quanta also
 experienced a claimed force majeure event which disrupted the
 project and Quanta provided the customer and its insurance
 providers with a notice of force majeure in order to seek schedule
 relief and cost recovery from disruptions. Quanta is also in the
 process of developing potential claims for damages that may have
 resulted from the third party engineering and other contractor
 performance issues; however, no revenues or cost recovery have been
 reflected in Quanta&amp;#x2019;s estimate of total project losses at
 June 30, 2016. The increase in estimated costs resulted in the
 recognition of a project loss of $30.5 million during the three
 months ended June 30, 2016. Project losses were $51.8 million
 during the six months ended June 30, 2016. At June 30, 2016, this
 project had a contract value of $201 million and was approximately
 90% complete. This project is expected to be substantially
 completed near the end of the third quarter of 2016. As this
 project continues through the final construction and commissioning
 phases, it is possible that additional performance issues or other
 unforeseen circumstances could occur and result in the recognition
 of additional losses on this project; however, such amounts cannot
 currently be estimated.&lt;/p&gt;

 six months ended June&amp;#xA0;30, 2016 were negatively impacted by
 9.2% and 6.7% as a result of aggregate changes in contract
 estimates related to projects that were in progress at
 December&amp;#xA0;31, 2015. Operating results for the three and six
 months ended June 30, 2016 included losses from the power plant
 construction project in Alaska mentioned above, offset by numerous
 individually immaterial changes in project profitability generally
 due to better than expected performance for projects that were
 ongoing at year-end. Quanta&amp;#x2019;s operating results for the three
 and six months ended June&amp;#xA0;30, 2015 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, 2014.
 Operating results for the three and six months ended June&amp;#xA0;30,
 2015 included losses of $31.8 million and $48.2 million related to
 three projects as a result of increased costs associated with
 performance and site related factors that adversely impacted
 production. These projects included the ongoing power plant
 construction project in Alaska, an electric transmission project in
 Canada that was substantially completed in the third quarter of
 2015, and a directional drilling project in Canada that was
 substantially completed in the fourth quarter of 2015. Operating
 results for the three and six months ended June&amp;#xA0;30, 2015 were
 impacted by positive changes in estimates of $8.5 million and $21.0
 million as a result of better than expected performance on an
 electric transmission project in the United States that was
 substantially completed in the second quarter of 2015.&lt;/p&gt;

 whether approved or unapproved by the customer, and/or claims
 related to certain contracts. Quanta determines the probability
 that such costs will be recovered based upon evidence such as past
 practices with the customer, specific discussions or preliminary
 negotiations with the customer or verbal approvals. Quanta treats
 items as a cost of contract performance in the period incurred if
 it is not probable that the costs will be recovered or will
 recognize revenue if it is probable that the contract price will be
 adjusted and can be reliably estimated. As of June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015, Quanta had approximately $106.0 million
 and $137.2 million of change orders and/or claims that had been
 included as contract price adjustments on certain contracts which
 were in the process of being negotiated in the normal course of
 business. 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;

 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 are classified in the provision for income
 taxes.&lt;/p&gt;

 unrecognized tax benefits relating to uncertain tax positions was
 $57.9 million, an increase from December&amp;#xA0;31, 2015 of $3.4
 million. This increase in unrecognized tax benefits resulted
 primarily from a $1.9 million increase due to tax positions
 expected to be taken for 2016 and a $1.9 million increase due to
 tax positions of an acquired company taken in periods prior to the
 acquisition. Quanta is currently under examination by the Internal
 Revenue Service (IRS) for tax years 2010, 2011 and 2012, and the
 federal statute of limitations for examination of all subsequent
 years remains open. Additionally, certain subsidiaries are 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 $25.9 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;

 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 realized 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. The cash flows resulting from the tax deductions in
 excess of the compensation expense recognized for restricted stock,
 RSUs and performance units to be settled in common stock and stock
 options (excess tax benefit) 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
 additional information on Quanta&amp;#x2019;s restricted stock, RSUs and
 performance unit awards, see Note 10.&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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 June&amp;#xA0;30, 2016 and December&amp;#xA0;31, 2015, 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;In connection with Quanta&amp;#x2019;s acquisitions,
 identifiable intangible assets acquired 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, 2015, 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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;

 &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, joint trenching projects to install distribution lines for
 electric power and natural gas customers. 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;

 and Oil and Gas Infrastructure Services segments, Quanta designs,
 installs and maintains networks for customers in the electric power
 and oil and gas 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" 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 our cost estimates or covered by our contracts for
 which we 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 our 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; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px" align="justify"&gt;During the six months ended June 30, 2016, Quanta
 experienced performance issues on an ongoing power plant project in
 Alaska that resulted in the revision of its estimate of total costs
 necessary to complete this project. During the first six months of
 2016 and as the project was planned to transition from final
 construction and testing to the commissioning phase, the project
 was negatively impacted by further third party engineering
 deficiencies that caused changes to Quanta&amp;#x2019;s planned scope of
 work and by performance failures by other contractors operating
 onsite. These issues resulted in higher than expected production
 costs and a related impact on production sequencing. In addition to
 these items, late in the second quarter of 2016 Quanta also
 experienced a claimed force majeure event which disrupted the
 project and Quanta provided the customer and its insurance
 providers with a notice of force majeure in order to seek schedule
 relief and cost recovery from disruptions. Quanta is also in the
 process of developing potential claims for damages that may have
 resulted from the third party engineering and other contractor
 performance issues; however, no revenues or cost recovery have been
 reflected in Quanta&amp;#x2019;s estimate of total project losses at
 June 30, 2016. The increase in estimated costs resulted in the
 recognition of a project loss of $30.5 million during the three
 months ended June 30, 2016. Project losses were $51.8 million
 during the six months ended June 30, 2016. At June 30, 2016, this
 project had a contract value of $201 million and was approximately
 90% complete. This project is expected to be substantially
 completed near the end of the third quarter of 2016. As this
 project continues through the final construction and commissioning
 phases, it is possible that additional performance issues or other
 unforeseen circumstances could occur and result in the recognition
 of additional losses on this project; however, such amounts cannot
 currently be estimated.&lt;/p&gt;

 six months ended June&amp;#xA0;30, 2016 were negatively impacted by
 9.2% and 6.7% as a result of aggregate changes in contract
 estimates related to projects that were in progress at
 December&amp;#xA0;31, 2015. Operating results for the three and six
 months ended June 30, 2016 included losses from the power plant
 construction project in Alaska mentioned above, offset by numerous
 individually immaterial changes in project profitability generally
 due to better than expected performance for projects that were
 ongoing at year-end. Quanta&amp;#x2019;s operating results for the three
 and six months ended June&amp;#xA0;30, 2015 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, 2014.
 Operating results for the three and six months ended June&amp;#xA0;30,
 2015 included losses of $31.8 million and $48.2 million related to
 three projects as a result of increased costs associated with
 performance and site related factors that adversely impacted
 production. These projects included the ongoing power plant
 construction project in Alaska, an electric transmission project in
 Canada that was substantially completed in the third quarter of
 2015, and a directional drilling project in Canada that was
 substantially completed in the fourth quarter of 2015. Operating
 results for the three and six months ended June&amp;#xA0;30, 2015 were
 impacted by positive changes in estimates of $8.5 million and $21.0
 million as a result of better than expected performance on an
 electric transmission project in the United States that was
 substantially completed in the second quarter of 2015.&lt;/p&gt;

 whether approved or unapproved by the customer, and/or claims
 related to certain contracts. Quanta determines the probability
 that such costs will be recovered based upon evidence such as past
 practices with the customer, specific discussions or preliminary
 negotiations with the customer or verbal approvals. Quanta treats
 items as a cost of contract performance in the period incurred if
 it is not probable that the costs will be recovered or will
 recognize revenue if it is probable that the contract price will be
 adjusted and can be reliably estimated. As of June&amp;#xA0;30, 2016
 and December&amp;#xA0;31, 2015, Quanta had approximately $106.0 million
 and $137.2 million of change orders and/or claims that had been
 included as contract price adjustments on certain contracts which
 were in the process of being negotiated in the normal course of
 business. 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;

 &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 2013, Quanta&amp;#x2019;s
 board of directors approved a stock repurchase program authorizing
 Quanta to purchase, from time to time through December&amp;#xA0;31,
 2016, up to $500.0 million of its outstanding common stock (the
 2013 Repurchase Program). During the nine months ended September
 30, 2015, Quanta repurchased 14.3 million shares of its common
 stock at a cost of $406.5 million in the open market under the 2013
 Repurchase Program and completed the 2013 Repurchase Program.&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 third quarter of 2015, Quanta&amp;#x2019;s
 board of directors approved a new stock repurchase program
 authorizing Quanta to purchase, from time to time through February
 28, 2017, up to $1.25 billion of its outstanding common stock (the
 2015 Repurchase Program). Repurchases under the 2015 Repurchase
 Program can be made in open market or privately negotiated
 transactions, including pursuant to an accelerated share repurchase
 arrangement, an issuer repurchase plan or otherwise, at
 management&amp;#x2019;s discretion, based on market and business
 conditions, applicable contractual and legal requirements and other
 factors. The 2015 Repurchase Program does not obligate Quanta to
 acquire any specific amount of common stock and may be modified or
 terminated by Quanta&amp;#x2019;s board of directors at any time at its
 sole discretion and without notice. During the third and fourth
 quarters of 2015, Quanta repurchased 19.2 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;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%" align="justify"&gt;Also during the third quarter of 2015, Quanta
 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 million shares of its common
 stock. The fair market value of these 25.7 million shares at the
 time of delivery was approximately $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 quarter ended September 30, 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 additional
 paid-in capital (APIC) during the quarter ended September 30, 2015
 and was reclassified from APIC to treasury stock on April&amp;#xA0;12,
 2016 as a result of the final settlement of the ASR. On
 April&amp;#xA0;12, 2016, upon final settlement of the ASR 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 million
 additional shares of its common stock from JPMorgan.&lt;/p&gt;

 of the ASR, Quanta had repurchased 54.3 million shares of its
 common stock at a cost of $1.20 billion under the 2015 Repurchase
 Program, and approximately $50.1 million remained available under
 the 2015 Repurchase Program.&lt;/p&gt;

 contracting company located in Canada. The results of these
 businesses will generally be included in Quanta&amp;#x2019;s Electric
 Power Infrastructure Services segment. The aggregate consideration
 paid or payable for these acquisitions was approximately $34.3
 million, subject to certain adjustments and certain contingent
 consideration payments of up to $4.5 million, which may be paid if
 certain financial targets are achieved. At Quanta&amp;#x2019;s election,
 a portion of the consideration and any contingent consideration may
 include shares of Quanta common stock. As these transactions were
 closed during the third quarter of 2016, the results will be
 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 electric
 power infrastructure service offerings in Australia and Canada.&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;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%" align="justify"&gt;In May 2014, the FASB issued an update that
 supersedes most current revenue recognition guidance as well as
 some cost recognition guidance. The update requires that an entity
 recognize revenue to depict the transfer of goods or services to
 customers in an amount that 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&amp;#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. Quanta is currently evaluating the
 potential impact of this authoritative guidance on its consolidated
 financial statements and will adopt this guidance effective
 January&amp;#xA0;1, 2018.&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 August 2014, the FASB issued guidance to address
 the diversity in practice in determining when there is substantial
 doubt about an entity&amp;#x2019;s ability to continue as a going
 concern and when and how an entity must disclose certain relevant
 conditions and events. This update requires an entity to evaluate
 whether there are conditions or events, considered in the
 aggregate, that raise substantial doubt about the entity&amp;#x2019;s
 ability to continue as a going concern for a period of one year
 after the date that the financial statements are issued (or
 available to be issued). If such conditions or events exist, an
 entity should disclose that there is substantial doubt about the
 entity&amp;#x2019;s ability to continue as a going concern for a period
 of one year after the date that the financial statements are issued
 (or available to be issued), along with the principal conditions or
 events that raise substantial doubt, management&amp;#x2019;s evaluation
 of the significance of those conditions or events in relation to
 the entity&amp;#x2019;s ability to meet its obligations and
 management&amp;#x2019;s plans that are intended to mitigate those
 conditions or events. The guidance is effective for annual and
 interim periods ending after December&amp;#xA0;15, 2016. This guidance
 will impact the disclosure and presentation of any substantial
 doubt by Quanta about its ability to continue as a going concern,
 if such substantial doubt were to exist. Quanta will adopt this
 guidance by 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;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.
 The update is required to be adopted prospectively and is effective
 for interim and annual reporting periods beginning after
 December&amp;#xA0;15, 2016, although early adoption is permitted.
 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, 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;In January 2016, the FASB issued an update that
 addresses certain aspects of recognition, measurement,
 presentation, and disclosure of financial instruments. The new
 standard is effective for interim and annual periods beginning
 after December&amp;#xA0;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&amp;#xA0;1, 2018.&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 February 2016, the FASB issued an update that
 requires companies that lease assets to recognize on the balance
 sheet the assets and liabilities for the rights and obligations
 created by those assets. The new standard is effective for interim
 and annual periods beginning after December&amp;#xA0;15, 2018. 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&amp;#xA0;1, 2019.&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 March 2016, the FASB issued an update that
 requires companies with share-based payments to record all of the
 tax effects related to such share-based payments at settlement (or
 expiration) through the income statement rather than through
 equity. It is anticipated that companies will experience increased
 volatility of income tax expense upon adoption of this update. This
 change is required to be applied prospectively to all excess tax
 benefits and tax deficiencies resulting from settlements after the
 date of the adoption of the update and is effective for interim and
 annual reporting periods beginning after December&amp;#xA0;15, 2016,
 although early adoption is permitted. 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, 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;In June 2016, the FASB issued an update that will
 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
 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;

 &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
 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;
