2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Principles of Consolidation
The condensed consolidated financial statements of Quanta include the accounts of Quanta Services, Inc. and its wholly-owned subsidiaries, which are also referred to as its operating units. The condensed consolidated financial statements also include the accounts of certain of Quanta’s investments in joint ventures, which are either consolidated or proportionately consolidated, as discussed in the following summary of significant accounting policies.consolidated. 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%, in the affiliated entity, 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.

Revenue Recognition
Contracts
Quanta designs, installs, upgrades, repairs and maintains infrastructure for customers in the electric power, energy and communications industries. TheseQuanta’s services may be provided pursuant to master service agreements (MSAs), repair and maintenance contracts and fixed price and non-fixed price installationconstruction contracts. These contracts are classified into three categories based on howthe methods by which transaction prices are determined and revenue is recognized: unit-price contracts, cost-plus contracts and fixed price contracts. Transaction prices for unit-price contracts are determined on a per unit basis, transaction prices for cost-plus contracts are determined by applying a profit margin to costs incurred on the contracts and transaction prices for fixed price contracts are determined on a lump-sum basis. All of Quanta’s revenues are recognized from contracts with its customers. In addition to the considerations described below, revenue is not recognized unless collectability under the contract is considered probable, the contract has commercial substance and the contract has been approved. Additionally, the contract must contain payment terms, as well as the rights and commitments of both parties.
Performance Obligations
A performance obligation is a promise in a contract with a customer to transfer a distinct good or service. Most of Quanta’s contracts are considered to have a single performance obligation whereby Quanta is required to integrate complex activities and equipment into a deliverable for a customer. For contracts with multiple performance obligations, Quanta allocates a portion of the total transaction price to each performance obligation using its best estimate of the standalone selling price of the distinct good or service associated with each performance obligation. Standalone selling price is estimated using the expected costs plus a margin.
At September 30, 20202021 and December 31, 2019,2020, the aggregate transaction price allocated to unsatisfied or partially satisfied performance obligations was approximately $4.44$4.37 billion and $5.30$3.99 billion, of which 70.2%78.7% and 59.5%71.2% were expected to be recognized in the subsequent twelve months. These amounts represent management’s estimateestimates of the consolidated revenues that are expected to be realized from the remaining portion of firm orders under fixed price contracts not yet completed or for which work had not yet begun.begun as of such dates. For purposes of calculating remaining performance

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)
obligations, Quanta includes all estimated revenues attributable to consolidated joint ventures and variable interest entities, revenues from funded and unfunded portions of government contracts to the extent they are reasonably expected to be realized and revenues from change orders and claims to the extent management believes additional contract revenues will be earned and are deemed probable of collection. Excluded from remaining performance obligations are potential orders under MSAs and non-fixed price contracts expected to be completed within one year.
Recognition of Revenue Upon Satisfaction of Performance Obligations
A transaction price is determined for each contract, and that amount is allocated to each performance obligation within the contract and recognized as revenue when, or as, the performance obligation is satisfied. Quanta generally recognizes revenue over time as it performs its obligations because there is a continuous transfer of control of the deliverable to the customer. Under unit-price contracts with an insignificant amount of partially completed units, Quanta recognizes revenue as units are completed based on contractual pricing amounts. Under unit-price contracts with more than an insignificant amount of partially completed units and fixed price contracts, Quanta recognizes revenues as performance obligations are satisfied over time, with the percentage completion generally measured as the percentage of costs incurred to total estimated costs for such performance obligation. Under cost-plus contracts, Quanta recognizes revenue on an input basis, as labor hours are incurred, materials are utilized and services are performed.
Under contracts where Quanta has a right to consideration in an amount that directly corresponds to the value of completed performance, Quanta recognizes revenue in such amount and does not include such performance as a remaining performance obligation. Also, contract consideration is not adjusted for a significant financing component if payment is expected to be collected less than one year from when the services are performed.
Contract costs include all direct materials, labor and subcontract costs and indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. The majority of the materials associated with Quanta’s work are owner-furnished, and therefore not included in contract revenues and costs. Additionally, Quanta may incur incremental costs to obtain certain contracts, such as selling and marketing costs, bid and proposal costs, sales commissions, and legal fees or initial set-up or mobilization costs, certain of which can be capitalized. Such costs were not material during the three and nine months ended September 30, 2020 and 2019.

Contract Estimates
Actual revenues and project costs can vary, sometimes substantially, from previous estimates due to changes in a variety of factors, including unforeseen or changed circumstances not included in Quanta’s cost estimates or covered by its contracts. The estimating process is based on the professional knowledge and experience of Quanta’s project estimators, project managers and finance professionals. Some of the factors that may lead tocan result in positive changes in estimates on projects include successful execution through project risks, reduction of estimated project costs or increases of estimated revenues. Some of the factors that can result in negative changes in estimates include concealed or unknown site conditions; changes to or disputes with customers regarding the scope of services; changes in estimates related to the length of time to complete a performance obligation; changes or delays with respect to permitting and regulatory requirements; changes in the cost or availability of equipment, commodities, materials or skilled labor; unanticipated costs or claims due to delays causedor failure to perform by customers or third parties; customer failure to provide required materials or equipment; errors in engineering, specifications or designs; project modifications or contract termination;modifications; adverse weather conditions, natural disasters, and other emergencies (including the ongoing pandemic as a result of the novel coronavirus disease (COVID-19) that began in 2019)COVID-19 pandemic); changes in estimates related to the length of time to complete a performance obligation; and performance and quality issues causing delay (including payment of liquidated damages) or requiring rework or replacement. These factors, along with other risks inherent in performing services under fixed price contracts, are routinely evaluated by management. Any changes in estimates couldmay result in changes to profitability or losses associated with the related performance obligations. For example, estimated costs for a performance obligation may increase from an original estimate and contractual provisions may not allow for adequate compensation or reimbursement for such additional costs.
Changes in estimated revenues, costs and profit are recognized on a cumulative catch-up basis and recorded in the period they are determined to be probable and can be reasonably estimated. Contract losses are recognized in full when they are determined to be probable and can be reasonably estimated.
Changes in cost estimates on certain contracts may result in the issuance of change orders, which can be approved or unapproved by the customer, or the assertion of contract claims. Quanta determines the probability that costs associated with change orders and claims will be recovered based on, among other things, contractual entitlement, past practices with the customer, specific discussions or preliminary negotiations with the customer and verbal approvals by the customer. Quanta recognizes amounts associated with change orders and claims as revenue if it is probable that the contract price will be adjusted and the amount of any such adjustment can be reliably estimated. Most of Quanta’s change orders are for services that are not distinct from an existing contract and are accounted for as part of an existing contract on a cumulative catch-up basis. Quanta accounts for a change order as a separate contract if the additional goods or services are distinct from and increase the scope of the contract, and the price of the contract increases by an amount commensurate to Quanta’s standalone selling price for the additional goods or services.
As of September 30, 2020 and December 31, 2019, Quanta had recognized revenues of $144.5 million and $170.0 million related to change orders and claims included as contract price adjustments and that were in the process of being negotiated in the normal course of business. These aggregate amounts, which are included in “Contract assets” in the accompanying condensed consolidated balance sheets, represent management’s estimates of additional contract revenues that have been earned and are probable of collection. However, Quanta’s estimates could change, and the amount ultimately realized could be significantly higher or lower than the estimated amount.
Variable consideration amounts, including performance incentives, early pay discounts and penalties, may also cause changes in contract estimates. The amount of variable consideration is estimated based on the most likely amount that is deemed probable of realization. Contract consideration is adjusted for variable consideration when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur once the uncertainty related to the variable consideration is resolved.
Changes in contract estimates are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Such changes in estimates can result in the recognition of revenue in a current period for performance obligations that were satisfied or partially satisfied in prior periods or the reversal of previously recognized revenue if the current estimate differs fromcurrently estimated revenue is less than the previous estimate. The impact of a change in contract estimate is measured as the difference between the revenue or gross profit recognized in the prior period as compared to the revenue or gross profit which would have been recognized had the revised estimate been used as the basis of recognition in the prior period. Changes in estimates can also result in contract losses, which are recognized in full when they are determined to be probable and can be reasonably estimated.
Operating results for the three months ended September 30, 2021 were favorably impacted by $41.9 million, or 7.8%, of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at June 30, 2021. Operating results for the nine months ended September 30, 2021 were favorably impacted by $127.4 million, or 9.4%, of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at December 31, 2020. The overall favorable impact resulted from net positive changes in estimates across a large number of projects, primarily as a result of favorable performance and successful mitigation of risks and contingencies as the projects progressed to completion.
Operating results for the three months ended September 30, 2020 were favorably impacted by $48.7 million, or 9.6%, of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at June 30, 2020. Operating results for the nine months ended September 30, 2020 were impacted by less than 5% of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at December 31, 2019.
Certain projects were materially impacted by changes to estimated contract revenues and/or project costs during the three and nine months ended September 30, 2020. Revenues and gross profit were favorably impacted as a result of successful execution through project risks and close-out activities on certain largerlarge pipeline projects in the United States, as well as a project scope reduction on a largerlarge pipeline project in the United States that allowed Quanta to recognize a portion of previously

deferred milestone payments and reduce certain contingencies on the project. The favorable impact related to these projects was partially offset by increased costs on two largerlarge pipeline projects in Canada that experienced severe weather conditions during the three and nine months ended September 30, 2020, both of which were substantially complete as of September 30, 2020. The remaining estimated costs to complete the two projects were $7.8 million as of September 30, 2020, with the primary remaining exposure to additional cost increases related to potential continued weather impacts.2021. With respect to all of these largerlarge pipeline projects, the aggregate net favorable impact on gross profit related to work performed in prior periods was $32.9 million and $15.1 million during the three and nine months ended September 30, 2020.
Additionally, during the three and nine months ended September 30, 2020, Quanta has beenwas pursuing the orderly exit of its Latin American operations.operations, which was substantially complete as of December 31, 2020. These operations have beenwere adversely impacted by the COVID-19 pandemic due to shelter-in-place restrictions and other work disruptions, and as a result Quanta has accelerated various contract terminations and other activities in order to expedite cessation of operations in the region. These factors have resulted in changes in estimates on several projects and negatively impacted gross profit related to work performed in prior periods by $12.1 million and $28.6 million in the aggregate during the three and nine months ended September 30, 2020.

Changes in cost estimates on certain contracts may also result in the issuance of change orders, which can be approved or unapproved by the customer, or the assertion of contract claims. As of September 30, 2021 and December 31, 2020, more than 80%Quanta had recognized revenues of $254.1 million and $141.2 million related to change orders and claims included as contract price adjustments that were in the process of being negotiated in the normal course of business. The largest component of the revenues recognized is associated with change orders and claims arising from delays on 2 electric transmission projects in Canada. The most significant delays on these projects occurred in the first and third quarters of 2021 and were related to the COVID-19 pandemic that negatively impacted productivity. Additionally, during the third quarter of 2021, both of the projects in Latin America that were active at the beginning of 2020 have been completed,negatively impacted by unrelated wildfires, and none1 was also impacted by acceleration of the remaining projects are expected to be individually material. The continuing uncertainty related to the potential duration and severityproject timeline, all of the COVID-19 pandemic in the region represents the primary risk that the remaining projects could experience further negative impacts to gross profit.

Operating results for the three months ended September 30, 2019 were favorably impacted by $29.2 million, or 6.2%, of gross profit, as a result of aggregate changes in contract estimates related to projects that were in progress at June 30, 2019. Operating results for the nine months ended September 30, 2019 were impacted by less than 5% of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at December 31, 2018.
Certain projects were materially impacted by changes to estimated contract revenues and/or project costs during the three and nine months ended September 30, 2019. Quanta successfully executed through project risks on a larger pipeline transmission project in the United States, which resulted in a reduction of estimated project costs and positively impacted gross profitchange orders. Quanta believes that the contracts for these projects entitle it to recover certain amounts associated with these delays. The aggregate amounts related to work performedchange orders and claims, which are included in prior periods by $22.2 million“Contract assets” in the accompanying condensed consolidated balance sheets, represent management’s estimates of additional contract revenues that have been earned and $21.6 million duringare probable of collection. However, Quanta’s estimates could change, and the three and nine months ended September 30, 2019. Quanta experienced unfavorable weather and labor-related impacts, as well as a project scope reduction, on an electric transmission project in southern California, which resulted in an increase inamount ultimately realized could be significantly higher or lower than the estimated project costs and a reduction in expected project earnings and negatively impacted gross profit related to work performed in prior periods by $11.0 million and $20.4 million during the three and nine months ended September 30, 2019. As of September 30, 2020, this project had a contract value of approximately $404.3 million and was approximately 93% complete.amount.
Quanta successfully completed an electric transmission project in Canada ahead of schedule, which resulted in a reduction in estimated project costs and positively impacted gross profit related to work performed in prior periods by $30.1 million during the nine months ended September 30, 2019. Quanta experienced rework and start-up delays on a processing facility construction project, which resulted in additional estimated project costs and liquidated damages payable to the customer and negatively impacted gross profit related to work performed in prior periods by $24.3 million during the nine months ended September 30, 2019. As of September 30, 2020, the processing facility construction project was complete.

Contract Assets and Liabilities
With respect to Quanta’s contracts, interim payments are typically received as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. As a result, under fixed price contracts, the timing of revenue recognition and contract billings results in contract assets and contract liabilities. Contract assets represent revenues recognized in excess of amounts billed for fixed price contracts and are current assets that are transferred to accounts receivable when billed or the billing rights become unconditional. Contract assets are not considered a significant financing component as they are intended to protect the customer in the event Quanta does not perform on its obligations under the contract.
Conversely, contract liabilities represent billings in excess of revenues recognized for fixed price contracts. These arise under certain contracts that allow for upfront payments from the customer or contain contractual billing milestones, which result in billings that exceed the amount of revenues recognized for certain periods. Contract liabilities are current liabilities and are not considered a significant financing component, as they are used to meet working capital requirements that are generally higher in the early stages of a contract and are intended to protect Quanta from the other party failing to meet its obligations under the contract. Contract assets and liabilities, are recorded on a performance obligation basis at the end of each reporting period.

Current and Long-Term Accounts Receivable Notes Receivable and Allowance for Credit Losses
As described in Note 3, Quanta adopted the new accounting standard for measuring credit losses effective January 1, 2020 utilizing the transition method that allows recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Quanta’s financial results for reporting periods beginning on or after January 1, 2020 are presented under the new standard, while financial results for prior periods continue to be reported in accordance with the prior standard and Quanta’s historical accounting policy. The net cumulative effect due to the adoption of the new standard was a $3.8 million reduction to retained earnings as of January 1, 2020, which represented a $5.1 million increase to allowance for
13

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)
credit losses, net of $1.2 million in deferred income taxes. The adjustment was based on an estimate of expected lifetime credit losses for financial instruments, primarily accounts receivable and contract assets. Although the adoption of the new standard did not have a material impact on Quanta’s condensed consolidated financial statements at the date of adoption, expected credit losses could change as a result of changes in credit loss experience, changes to specific risk characteristics of Quanta’s portfolio of financial assets or changes to management’s expectations of future economic conditions that affect the collectability of Quanta’s financial assets. At the end of each quarter, management reassesses these factors, including any potential effects from the ongoing COVID-19 pandemic.
The assessment of the allowance for credit losses involves certain judgments and estimates. Management estimates the allowance balance using relevant available information from internal and external sources relating to past events, current conditions and reasonable and supportable forecasts. Expected credit losses are estimated by evaluating trends in historical write-off experience and applying historical loss ratios to pools of financial assets with similar risk characteristics. Quanta has determined that it has 1 pool for the purpose of calculating its historical credit loss experience.
Quanta’s historical loss ratio and its determination of risk pools, which are used to calculate expected credit losses, may be adjusted for changes in customer credit concentrations within its portfolio of financial assets, its customers’ ability to pay, and other considerations, such as economic and market changes, changes to the market, regulatory or technological environments affecting its customers and the consistency of thebetween current and forecasted economic conditions relative to theand historical periodeconomic conditions used to derive historical loss ratios. At the end of each quarter, management reassesses these and other relevant factors, including any potential effects from the currently challenged energy market and the ongoing COVID-19 pandemic.
Additional allowance for credit losses is established for financial asset balances with specific customers where collectability has been determined to be improbable based on customer specific facts and circumstances. Quanta considers accounts receivable delinquent after 30 days but does not generally consider such amounts delinquent in its credit loss analysis unless the accounts receivable have been outstanding forare at least 90 days.days past due. In addition to monitoring delinquent accounts, management monitors the credit quality of its receivables by, among other things, obtaining credit ratings of significant customers, assessing economic and market conditions and evaluating material changes to a customer’s business, cash flows and financial condition. Should anticipated recoveries relating to receivables fail to materialize, including anticipated recoveries relating to bankruptcies or other workout situations, Quanta could experience reduced cash flows and losses in excess of current allowances provided.
For example, in July 2021 Limetree Bay Refining, LLC (Limetree Refining), a customer within Quanta’s Underground Utility and Infrastructure Solutions segment, filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, as amended, after experiencing operational and financial difficulties and shutting down operations at its refinery. As of September 30, 2021, Quanta had $31.3 million of billed and unbilled receivables for services performed and other costs. Quanta also had $0.7 million of billed and unbilled receivables outstanding from Limetree Bay Terminals, LLC (Limetree Terminals), an affiliate of Limetree Refining that has not filed for bankruptcy. During the three months ended June 30, 2021, Quanta recorded a provision for credit loss of $23.6 million with respect to these receivables based on the current estimated amount of expected loss. However, given the uncertainties associated with the bankruptcy proceeding and the financial condition of the customers, the amount of receivables ultimately collected and the ultimate amount of credit loss recognized depends on a number of factors that are subject to change, including, among other things, the potential sale of the refinery assets by Limetree Refining, negotiations with respect to payment of the amounts owed by Limetree Terminals and the result of any preferential payment actions brought in the bankruptcy proceeding. As such, an additional allowance for credit loss may be recorded in the future, including with respect to the remaining $8.4 million of receivables owed by the customers. See Concentrations of Credit Risk in Note 10 for further discussion of the credit quality of certain other outstanding receivables due from customers that have experienced financial difficulties.

These balances do not include revenues recognized for work performed under fixed-price contracts, as these amounts are recorded as “Contract assets.” At September 30, 20202021 and December 31, 2019,2020, unbilled receivables included

in “Accounts receivable” were $721.4$827.3 million and $524.3$472.3 million. The increase in unbilled receivables was primarily due to the ramp up of work, certain delays in billing related to a large customer and a significant amount of emergency restoration services revenues performed in the latter part of the third quarter that remained unbilled at the end of the quarter. Quanta also recognizes unearned revenues for non-fixed price contracts when cash is received prior to recognizing revenues for the related performance obligation. Unearned revenues, which are included in “Accounts payable and accrued expenses,” were $36.0$39.5 million and $33.2$53.6 million at September 30, 20202021 and December 31, 2019.2020.

Goodwill and Other Intangible Assets
Goodwill, net of accumulated impairment losses, represents the excess of cost over the fair market value of net tangible and identifiable intangible assets of acquired businesses and is stated at cost. Quanta has recorded goodwill in connection with its historical acquisitions of businesses. Upon acquisition, these businesses were either combined into one of Quanta’s existing operating units or managed on a stand-alone basis as an individual operating unit. Quanta’s operating units are organized into 2 divisions: the Electric Power Infrastructure Services Division and the Pipeline and Industrial 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 an 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 impairment.
Goodwill is not amortized but is tested for impairment annually in the fourth quarter of the fiscal year, or more frequently if events or circumstances arise which indicate
16

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)
that goodwill may be impaired. The assessment can be performed by first completing a qualitative assessment on none, some or all of Quanta’s reporting units. Quanta can also bypass the qualitative assessment for any reporting unit in any period and proceed directly to a quantitative impairment test, and then resume the qualitative assessment in any subsequent period. Qualitative indicators that may trigger the need for annual or interim quantitative impairment testing include, among other things, deterioration in macroeconomic conditions,conditions; declining financial performance,performance; deterioration in the operational environment, orenvironment; an expectation of selling or disposing of a portion of a reporting unit. Additionally, an interim impairment test of a reporting unit may be triggered byunit; a significant change in market,

management, business strategy or business climate; a loss of a significant customer; increased competition; a sustained decrease in share price; or a decrease in Quanta’s market capitalization below book value.
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. The quantitative test involves comparing the fair value of each of Quanta’s reporting units with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recorded as a reduction to goodwill with a corresponding charge to “Asset impairment charges” in the condensed consolidated statements of operations. The income tax effect associated with an impairment of tax-deductible goodwill is also considered in the measurement of the goodwill impairment. A goodwill impairment for any reporting unit is limited to the total amount of goodwill allocated to such reporting unit.
Quanta determines the fair value of its reporting units using a weighted combination of the income approach (discounted cash flow method) and market multiples valuation techniques (market guideline transaction method and market guideline public company method), with greater weight placed on the discounted cash flow method because management believes this method results in the most appropriate calculation of fair value and reflects an expectation of market value as determined by a “held and used” model.
Under the discounted cash flow method, Quanta determines fair value based on the estimated future cash flows for each reporting unit, discounted to present value using a risk-adjusted industry weighted average cost of capital, which reflects the overall level of inherent risk for each reporting unit and the rate of return an outside investor would expect to earn. Cash flow projections are derived from budgeted amounts (typically a one-year model) and subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonably likely to occur. A terminal value is derived from a multiple of the reporting unit’s earnings before interest, taxes, depreciation and amortization (EBITDA). The EBITDA multiples for each reporting unit are based on observed purchase transactions for similar businesses adjusted for size, volatility and risk.
Under the market guideline transaction and market guideline public company methods, Quanta determines the estimated fair value for each of its reporting units by applying transaction multiples and public company multiples, respectively, to each reporting unit’s projected EBITDA and then averaging that estimate with similar historical calculations using either a one-, two- or three-year average. The transaction multiples are based on observed purchase transactions for similar businesses adjusted for size, volatility and risk. The public company multiples are based on peer group multiples adjusted for size, volatility and risk. For the market guideline public company method, Quanta adds a reasonable control premium, which is estimated as the premium that would be appropriate to convert the reporting unit value to a controlling interest basis.
For Quanta’s annual goodwill impairment assessment performed during the fourth quarter of 2019, Quanta assessed qualitative factors to determine whether it was necessary to perform a quantitative fair value impairment analysis and identified 1 reporting unit for which a quantitative goodwill impairment assessment was deemed appropriate based on financial performance indicators. The subsequent quantitative analysis indicated that the fair value of the reporting unit was in excess of its carrying amount. Accordingly, Quanta did not recordidentify any impairment charges related to goodwill during the fourth quarter of 2019.
The determination of a reporting unit’s fair value requires judgment and the use of significant estimates and assumptions. Quanta believes the estimates and assumptions used in its impairment assessments are reasonable and based on available market information obtained from relevant industry sources; however, variations in any of the assumptions could result in materially different calculations of fair value and impairment determinations. Accordingly, management considered the sensitivity of its fair value estimates to changes in certain valuation assumptions. After taking into account a 10% decreasetriggering events in the fair valuefirst three quarters of the reporting unit2021 and did not recognize any goodwill impairments for which a quantitative impairment test was performed in the fourth quarter of 2019, the reporting unit’s fair value exceeded its carrying amount.
If an operating unit experiences prolonged periods of declining revenues, operating margins or both, it may be at risk of failing the quantitative goodwill impairment test. The reporting unit referenced above, for which a quantitative goodwill impairment assessment was performed in the fourth quarter of 2019, experienced declines over the short-term primarily due to losses attributable to a project which are not expected to recur.
Due to the cyclical nature of Quanta’s business, and the other factors described above, the profitability of its individual reporting units may suffer from decreases in customer demand and other factors. These factors may have a disproportionate impact on individual reporting units as compared to Quanta as a whole and might adversely affect the fair value of individual reporting units. If material adverse conditions occur, Quanta’s future estimates of fair value may not support the carrying amount of one or more of its reporting units, and the related goodwill would need to be written down to an amount considered recoverable.

As a result of the currently challenged energy market, including the recent significant decline in commodity prices and volatility in commodity production volumes, the effect of which has been exacerbated by the COVID-19 pandemic, Quanta assessed the expected negative impacts related to its reporting units, particularly reporting units within its Pipeline and Industrial Infrastructure Services Division. Quanta concluded that such impacts are not likely to result in a goodwill impairment for any reporting unit at this time. As a result, 0 goodwill impairment was recognized during the three and nine months ended September 30, 2020. However, the potential impact of the energy market challenges and the COVID-19 pandemic is uncertain and depends on numerous factors, and therefore the negative impact on certain of Quanta’s reporting units could increase in future periods. Quanta will continue to monitor the impact of these events and should any of its reporting units suffer additional declines in actual or forecasted financial results, the risk of goodwill impairment would increase.
Other Intangible Assets2021.
Quanta’s intangible assets include customer relationships, backlog,relationships; backlog; trade names,names; non-compete agreements,agreements; patented rights, and developed technology, and process certifications; and curriculum, all of which are subject to amortization, as well as an engineering license, which is not subject to amortization. The fair 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 multi-period excess earnings method. This method discounts 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 significant estimates used by management in determining the fair values of customer relationship intangible assets include future revenues, discount rates and customer attrition rates. The following table presents the range and weighted average based on acquisition date fair value for discount and attrition rates used in the valuation of customer relationship intangible assets during the nine months ended September 30, 2020 and year ended December 31, 2019:
 20202019
RangeWeighted AverageRangeWeighted Average
Discount rates19% to 23%20%19% to 24%24%
Customer attrition rates10% to 43%11%5% to 37%6%
Quanta values backlog for acquired businesses as of the acquisition date based upon the contractual nature of the backlog within each service line, discounted to present value. The values of trade names and curriculum are estimated using the relief-from-royalty method of the income approach, which is based on the assumption that in lieu of ownership, a company would be willing to pay a royalty for use of the trade name or curriculum. The value of a non-compete agreement is estimated based on the difference between the present value of the prospective cash flows with the agreement in place and the present value of the prospective cash flows without the agreement in place. The value of the engineering license is based on cash paid to acquire the asset.
Quanta amortizes the intangible assets that are subject to amortization based upon the estimated consumption of their economic benefits, or on a straight-line basis if the pattern of economic benefit cannot otherwise be reliably estimated. Intangible assets are reviewed for impairment and 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 is recognized if the carrying amount of an intangible asset is not recoverable and its carrying amount exceeds its fair value.
As a result of the currently challengedbroader challenges in the energy market, including the recent significant decline in commodity prices and volatility in commodity production volumes, the effect of which has beencontinues to be exacerbated by the COVID-19 pandemic, Quanta assessed the expected negative impactsimpact related to its intangible assets, particularly intangible assets associated with reporting units within the PipelineUnderground Utility and Industrial Infrastructure ServicesSolutions Division. Quanta concluded that such impacts areimpact is not likely to result in intangible asset impairments, at this time. As a result, 0and therefore no intangible asset impairment wasimpairments were recognized during the three and nine months ended September 30, 2020. However,2021.
In connection with its annual goodwill assessment in 2020, Quanta also considered the sensitivity of its fair value estimates to changes in certain valuation assumptions, including with respect to reporting units within Quanta’s Underground Utility and Infrastructure Solutions Division that have recently been negatively impacted by energy market challenges. The potential future impact of the energy marketthese challenges and of the COVID-19 pandemic is uncertain and depends on numerous factors and therefore the negative impact on certain of Quanta’s reporting units and related intangible assets could continue or increase in future periods. In particular, 2 Canadian pipeline-related businesses and a United States material handling services business were identified in the annual goodwill assessment to have an increased risk of goodwill impairment in the near and medium term due to the currently challenged energy market. After taking into account a 10% decrease in fair value, these reporting units would have had fair values below their carrying amounts as of December 31, 2020. The aggregate goodwill and intangible asset balances for these 3 businesses totaled $100.1 million and $16.0 million as of September 30, 2021. In addition, a specialized industrial services business located in the United States experienced lower demand for certain services during the year ended December 31, 2020, which has continued in 2021, as customers reduced and deferred regularly scheduled maintenance due to lack of demand for refined products, particularly certain transportation-related fuels, as a result of the COVID-19 pandemic. After taking into account a 10% decrease in fair value, the reporting unit would have had a fair value in excess of its carrying amount as of December 31, 2020; however, uncertainty as to the timing and extent of recovery of demand for refined products has increased the risk of goodwill impairment for this reporting unit. The goodwill and intangible asset balances for this reporting unit were $313.4 million and $51.9 million as of September 30, 2021. Quanta will continue to monitor the impact ofgoodwill associated with these eventsreporting units, and should any of the reporting unitsthey suffer additional declines in actual or forecasted financial results, the risk of intangible assetgoodwill impairment would increase.

Leases
Lease liabilities are recognized as the present value of the future minimum lease payments over the lease term as of the commencement date. Lease assets are recognized as the present value of future minimum lease payments over the lease term as of the commencement date, plus any initial direct costs incurred and lease payments made, less any lease incentives received.
Quanta determines if an arrangement contains a lease at inception. If an arrangement is considered a lease, Quanta determines at the commencement date whether the lease is an operating or finance lease. Finance leases are leases that meet any of the following criteria: the lease transfers ownership of the underlying asset at the end of the lease term; the lessee is reasonably certain to exercise an option to purchase the underlying asset; the lease term is for the major part of the remaining economic life of the underlying asset (except when the commencement date falls at or near the end of such economic life); the present value of the sum of the lease payments and any additional residual value guarantee by the lessee equals or exceeds substantially all of the fair value of the underlying asset; or the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. A lease that does not meet any of these criteria is considered an operating lease. After the commencement date, lease cost for an operating lease is recognized over the remaining lease term on a straight-line basis, while lease cost for a finance lease is based on the depreciation of the lease asset and interest on the lease liability.
The terms of Quanta’s lease arrangements vary, and certain leases include one or more of the following: renewal option(s), a cancellation option, a residual value guarantee, a purchase option or an escalation clause. An option to extend or terminate a lease is accounted for when assessing a lease term when it is reasonably certain that Quanta will exercise such option. Quanta has made a policy election to classify leases with an initial lease term of 12 months or less as short-term leases, and these leases are not recorded in the accompanying condensed consolidated balance sheets unless the lease contains a purchase option that is reasonably certain to be exercised. Lease cost related to short-term leases is recognized on a straight-line basis over the lease term.
Determinations with respect to lease term (including any extension thereof), discount rate, variable lease cost and future minimum lease payments require the use of judgment based on the facts and circumstances related to each lease. Quanta considers various factors, including economic incentives and penalties and business need, to determine the likelihood that a renewal option will be exercised. Unless a renewal option is reasonably certain to be exercised, which is typically at Quanta’s sole discretion, the initial non-cancelable lease term is used. Quanta generally uses its incremental borrowing rates to determine the present value of future minimum lease payments.
Investments in Affiliates and Other Entities
In the normal course of business, Quanta enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by Quanta in business entities, including general or limited partnerships, contractual joint ventures, or other forms of equity or profit participation. These investments may also include Quanta’s participation in different financing structures, such as the extension of loans to project-specific entities, the acquisition of convertible notes issued by project specific entities, or other strategic financing arrangements. Quanta also enters into strategic partnerships with customers and infrastructure investors to provide fully integrated infrastructure services on certain projects, including planning and feasibility analyses, engineering, design, procurement, construction and project operation and maintenance. These projects include public-private partnerships and concessions, along with private infrastructure projects such as build, own, operate (and in some cases transfer) and build-to-suit arrangements.
Quanta determines whether 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) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb significant losses of, or the right to receive significant benefits from, the VIE. When Quanta is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a 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’s ownership interest in the unincorporated entity.
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. Equity method investments are carried at original cost adjusted for Quanta’s proportionate share of the investees’ income, losses and distributionsdistributions. The carrying values for Quanta’s unconsolidated equity method investments were $73.8 million and $44.9 million at September 30, 2021 and December 31, 2020 and are included in “Other assets, net” in the accompanying condensed consolidated balance sheets.

Investments in entities of which Quanta is not the primary beneficiary, and over which Quanta does not have the ability to exercise significant influence are accounted for using the cost method of accounting. Additionally, certain investments provide for significant influence over the investee, but also include preferential liquidation rights, which precludes accounting for the investments under the equity method. These cost method investments are required to be measured at fair value, with changes in fair value recognized in net income unless the investments do not have readily determinable fair values, in which case the investments are measured at cost minus impairment if any,(if any), plus or minus observable price changes in orderly transactions for an identical or similar investment in the same company. Earnings on investments accounted for using the cost method of accounting are recognized as dividends are received.declared. These earnings and any impairments of cost method investments are reported in “Other income (expense), net” in the accompanying condensed consolidated statements of operations.
The carrying values for investments accounted for using the cost method of accounting were $130.2 million and $39.5 million at September 30, 2021 and December 31, 2020, and these amounts are included in “Other assets, net” in the accompanying condensed consolidated balance sheets. During the three months ended March 31, 2021, Quanta acquired a minority interest in a broadband technology provider for $90.0 million. This investment includes preferential liquidation rights and is accounted for using the cost method of accounting. There have been no changes in the carrying value of the investment through September 30, 2021.
During the three months ended March 31, 2021, Quanta also purchased, through its wholly-owned captive insurance company, certain real property, including associated buildings and facilities, that is expected to be developed for its future corporate headquarters. A portion of this property is currently leased to third-party lessees and is expected to continue to be leased to third-party lessees in the future. As a result, an investment in real estate of $23.5 million was recognized at cost for the third-party leased portion of the property during the three months ended March 31, 2021, and the carrying amount of $23.4 million is included in “Other assets, net” in the accompanying condensed consolidated balance sheet at September 30, 2021.
During the three months ended June 30, 2020, Quanta recognized a $9.3 million impairment to an investment in a water and gas infrastructure contractor, which also represents the cumulative amount of impairment on investments accounted for using the cost method of accounting. Quanta did not exercise its option to acquire the remaining interest in this business at an agreed price based on a multiple of the company’s earnings during a designated performance period.
See Note 10 for additional information related to investments.
Puerto Rico Joint Venture
During the three months ended June 30, 2020, a joint venture in which Quanta owns a 50% interest, LUMA Energy, LLC (LUMA), was selected for a 15-year operation and maintenance agreement to operate, maintain and modernize the approximately 18,000-mile electric transmission and distribution system in Puerto Rico. The 15-year operation and maintenance period is expected to begin following an approximately one-year transition period, during whichIn June 2021, LUMA will complete numerouscompleted the steps necessary to transition operation and maintenance of the system from the current operatorowner to LUMA.LUMA and entered into an interim services agreement. Once the owner emerges from its Title III debt restructuring process, the 15-year operation and maintenance period is scheduled to begin. During the transitioninterim services period, LUMA receives a fixed transition servicesannual management fee, payable in monthly installments, and is reimbursed for costs and expenses. During the 15-year operation and maintenance period, LUMA will continue to be reimbursed for costs and expenses and will receive a fixed annual management fee, withbut will also have the opportunity to receive additional annual performance-based incentive fees. LUMA has not assumed and will not assume ownership of any electric transmission and distribution system assets and will notor be responsible for operation of the power generation assets. Quanta’s ownership interest and participation in LUMA is accounted for as an equity method investment due to Quanta’s equal ownership and management of LUMA with its joint venture partner. LUMA is operationally integral to the operations of Quanta, and therefore Quanta’s share of LUMA’s net income or losses is reported within operating income in “Equity in earnings (losses) of integral unconsolidated affiliates.” AsIncluded within the equity method investments described above are Quanta’s equity interest in LUMA of $34.5 million and $10.9 million at September 30, 2020, Quanta’s investment balance related to LUMA was $5.3 million.
As part of Quanta’s investment strategy, Quanta formed a partnership in 2017 with select investors to invest in certain specified infrastructure projects,2021 and wholly-owned subsidiaries of Quanta serve as the general partner of this partnership and as a separately operated registered investment adviser that manages the invested capital. As of September 30, 2020, Quanta’s investment balance related to this partnership was $21.4 million. In October 2019, due to certain management changes at the registered investment adviser, the partnership entered into a 180-day period during which the investors and Quanta evaluated the partnership, and at the end of such period in April 2020, the investment period for any future investments ended.
Quanta held a minority ownership interest in a limited partnership that was selected during 2014 to build, own and operate a new 500 kilometer electric transmission line and 2 500 kV substations in Alberta, Canada and accounted for this interest as an equity-method investment. The limited partnership contracted with a Quanta subsidiary to perform the engineering, procurement and construction (EPC) services for the project, and the Quanta subsidiary recognized revenue and related cost of services as performance progressed on the project. However, due to Quanta’s ownership interest, a proportional amount of the EPC profit was deferred until the electric transmission line and related substations were constructed and ownership of the assets was deemed to be transferred to the third-party customer, which occurred in the three months ended March 31, 2019. The deferral of earnings and recognition of such earnings deferral were recorded as components of equity in earnings (losses) of non-integral unconsolidated affiliates, which is included in “Other income (expense), net” in the accompanying condensed consolidated statements of operations. During the three months ended March 31, 2019, deferred earnings of $60.3 million were recognized, the majority of which was attributable to profit earned and deferred in the years ended December 31, 2018 and 2017. During the three months ended December 31, 2019, Quanta sold its minority ownership interest in the limited partnership and recognized a gain of $13.0 million related to the sale.

Accounts payable and accrued expenses consisted of the company at an agreed price based on a multiple of the company’s earnings during a designated performance period that ended April 30, 2020. Based on this option price, Quanta determined that its investment was impaired and recorded an impairment charge of $9.3 million during the three months ended June 30, 2020. Such impairment is included in “Other income (expense), net” in the accompanying condensed consolidated statements of operations.following (in thousands):
As a result of the currently challenged energy market, including the recent significant decline in commodity prices and volatility in commodity production volumes, the effect of which has been exacerbated by the COVID-19 pandemic, Quanta assessed the expected negative impacts related to certain of its investments, particularly investments dependent on the energy market. This assessment contributed in part to management’s decision to record the impairments related to certain non-integral equity method investments and the water and gas pipeline infrastructure contractor in Australia described above. Additionally, the potential impact of the energy market challenges and the COVID-19 pandemic remains uncertain and may change based on numerous factors, which could further negatively impact these and other of Quanta’s investments. Quanta will continue to monitor the potential impacts of these events, and should any investments suffer additional declines in actual or forecasted financial results, additional impairments may be required. See Notes 9 and 11 for additional information related to investments.

Income Taxes
Quanta follows the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded based on future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled.
Quanta regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain, including in connection with changes in tax laws. The estimation of required valuation allowances includes estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Quanta considers projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from these estimates, Quanta may not realize deferred tax assets to the extent estimated.
Quanta records reserves for income taxes related to certain tax positions when management considers it more likely than not that additional taxes may be due in excess of amounts reflected on income tax returns filed. When recording these reserves, Quanta assumes that taxing authorities have full knowledge of the position and all relevant facts. Quanta continually reviews exposure to additional tax obligations, and as further information is known or events occur, changes in tax reserves may be recorded. To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts have been accrued and included in the provision for income taxes.
As of September 30, 2020,2021, the total amount of unrecognized tax benefits relating to uncertain tax positions was $40.8$40.6 million, a decreasean increase of $0.1$7.4 million from December 31, 2019. This decrease2020. The increase resulted primarily from a $3.4$5.0 million increase in reserves for uncertain tax positions expected to be taken in 2020, offset by2021 and a settlement of $3.4$2.4 million increase related to certain U.S. and non-U.S.prior year positions. Quanta’s consolidated federal income tax audits.return for tax year 2019 is currently under examination by the Internal Revenue Services (IRS), and Quanta’s consolidated federal income tax returns for tax years 2017, 2018, and 2020 remain open to examination by the IRS, as these statute of limitations periods have not yet expired. Additionally, various state and foreign tax returns filed by Quanta and certain subsidiaries for multiple periods remain under examination by various U.S. state and foreign tax authorities for multiple periods.authorities. Quanta believes it is reasonably possible that within the next 12 months unrecognized tax benefits may decrease by up to $10.0$13.3 million as a result of settlement of these examinations or as a result of the expiration of certain statute of limitations periods.
U.S. federal and state and foreign income tax laws and regulations are voluminous and 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 future consolidated balance sheets, statements of operations and statements of comprehensive income. For example, the Tax Cuts and Jobs Act of 2017 significantly revised the U.S. corporate tax regime which, among other things, resulted in a reduction of Quanta’s current and estimated future effective tax rate and a remeasurement of its deferred tax assets and liabilities.
Earnings Per Share
Basic and diluted earnings per share attributable to common stock are computed using the weighted average number of shares of common stock outstanding during the applicable period. Exchangeable shares that were issued pursuant to certain of Quanta’s historical acquisitions (as further discussed in Note 9), which were exchangeable on a 1-for-one basis with shares of Quanta common stock, have been included in the calculation of weighted average shares outstanding for basic and diluted earnings per share attributable to common stock for the portion of the periods that they were outstanding. Additionally,

(Unaudited)
unvested stock-based awards that contain non-forfeitable rights to dividends or dividend equivalents (participating securities) have been included in the calculation of basic and diluted earnings per share attributable to common stock for the portion of the periods that the awards were outstanding. Diluted earnings per share attributable to common stock is computed using the weighted average number of shares of common stock outstanding during the period adjusted for all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalents would be antidilutive.
Insurance
Quanta is insured for employer’s liability, workers’ compensation, auto liability and general liability claims. Under these insurance programs, as of September 30, 2020, the deductible for employer’s liability was $5.0 million per occurrence; the deductible for workers’ compensation was $5.0 million per occurrence; and the deductibles for auto liability and general liability were $15.0 million per occurrence. Quanta manages and maintains a portion of its casualty risk through its wholly-owned captive insurance company, which insures all claims up to the amount of the applicable deductible of its third-party insurance programs. In connection with Quanta’s casualty insurance programs, Quanta is required to issue letters of credit to secure its obligations. Quanta also has employee health care benefit plans for most employees not subject to collective bargaining agreements, of which the primary plan is subject to a deductible of $0.8 million per claimant per year.
Losses under all of these insurance programs are accrued based upon Quanta’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’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.
Collective Bargaining Agreements
Certain of Quanta’s operating units are parties to 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 union employees and contribute certain amounts to multiemployer pension plans and employee benefit trusts pursuant to specified rates. Quanta’s multiemployer pension plan contribution rates generally are made to the plans on a “pay-as-you-go” 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 Quanta’s need for union resources in connection with its ongoing projects. Therefore, Quanta is unable to accurately predict its union employee payroll and the resulting multiemployer pension plan contribution obligations for future periods.
Stock-Based Compensation
Quanta recognizes compensation expense for restricted stock units (RSUs) and performance stock units (PSUs) to be settled in common stock based on the fair value of the awards, net of estimated forfeitures. The fair value of RSU awards is determined based on the number of units granted and the closing price of Quanta’s common stock on the date of grant. The grant date fair value of the PSUs is determined as follows: (i) for the portion of the awards based on company performance metrics, by multiplying the number of units granted by the closing price of Quanta’s common stock on the date of grant and (ii) for the portion of the awards based on relative total shareholder return, by utilizing a Monte Carlo simulation valuation methodology. An estimate of future forfeitures, based on historical data, is also utilized to determine compensation expense for the period, and these forfeiture estimates are subject to change and may impact the value that will ultimately be recognized as compensation expense. The resulting compensation expense for PSU and time-based RSU awards is recognized on a straight-line basis over the requisite service period, which is generally the vesting period, and the resulting compensation expense for performance-based RSU awards is recognized using the graded vesting method over the requisite service period. The compensation expense related to outstanding PSUs can also vary from period to period based on changes in forecasted achievement of established performance goals and the total number of shares of common stock that Quanta anticipates will be issued upon vesting of such PSUs. Payments made by Quanta to satisfy employee tax withholding obligations associated with awards settled in common stock are classified as financing cash flows.
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 of 1 share of Quanta common stock on the settlement date, as specified in the applicable award agreement. For additional information on Quanta’s RSU and PSU awards, see Note 10.

Functional Currency and Translation of Financial Statements
The U.S. dollar is the functional currency for the majority of Quanta’s operations, which are primarily located within the United States. The functional currency for Quanta’s foreign operations, which are primarily located in Canada and Australia, is typically the currency of the country where the foreign operating unit is located and transacts the majority of its activities, including billings, financing, payroll and other expenditures. When preparing its 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 “Accumulated other comprehensive income (loss).” Gains and losses arising from transactions not denominated in functional currencies are included within “Other income (expense), net” in the accompanying condensed consolidated statements of operations.
Comprehensive Income
Components of comprehensive income include all changes in equity during a period except those resulting from changes in Quanta’s capital-related accounts. Quanta records other comprehensive income (loss) for foreign currency translation adjustments related to its foreign operations and for other revenues, expenses, gains and losses that are included in comprehensive income but excluded from net income.
Litigation Costs and Reserves
Quanta records reserves when the likelihood of incurring a loss is probable and the amount of loss can be reasonably estimated. Costs incurred for litigation are expensed as incurred. See Note 11 for additional information related to legal proceedings and other contingencies.
Fair Value Measurements
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). Certain assumptions and other information as they relate to these qualifying assets and liabilities are described below.
Contingent Consideration Liabilities. As of September 30, 2020 and December 31, 2019, financial instruments required to be measured at fair value on a recurring basis consisted primarily of Quanta’s liabilities related to contingent consideration associated with certain acquisitions, payable in the event certain performance objectives are achieved by the acquired businesses during designated post-acquisition periods. The liabilities recorded represent the estimated fair values of future amounts payable to the former owners of the acquired businesses and are estimated by management based on entity-specific assumptions that are evaluated on an ongoing basis.
Aggregate fair values of these outstanding contingent consideration liabilities and their classification in the accompanying condensed consolidated balance sheets were as follows (in thousands):
 September 30, 2020December 31, 2019
Accounts payable and accrued expenses$68,466 $77,618 
Insurance and other non-current liabilities7,383 6,542 
Total contingent consideration liabilities$75,849 $84,160 
The measurement period for approximately $65.0 million of Quanta’s outstanding contingent consideration liabilities was complete as of September 30, 2020. The remaining contingent consideration liabilities have an approximate aggregate fair value of $10.8 million, and the majority are subject to a maximum outstanding payment amount, which totaled $48.6 million as of September 30, 2020.
The fair values of these liabilities were primarily determined using a Monte Carlo simulation valuation methodology based on probability-weighted performance projections and other inputs, including a discount rate and an expected volatility factor for each acquisition. The inputs for the remaining liabilities include an expected volatility factor of 30.0% based on historical asset volatility of selected guideline public companies. Depending on contingent consideration payment terms, the present values of the estimated payments are discounted based on a risk-free rate and/or Quanta’s cost of debt, which ranged from 0.1% to 3.9% as of September 30, 2020 and had a weighted average of 2.4% based on fair value at acquisition. The fair value determinations incorporate significant inputs not observable in the market. Accordingly, the level of inputs used for these

fair value measurements is the lowest level (Level 3). Significant changes in any of these assumptions could result in a significantly higher or lower potential liability.
Quanta’s aggregate contingent consideration liabilities can change due to additional business acquisitions, settlement of outstanding liabilities, changes in the fair value of amounts owed based on performance in post-acquisition periods and accretion in present value. During the three and nine months ended September 30, 2020, Quanta recognized net increases of $0.1 million and $0.6 million in the fair value of its aggregate contingent consideration liabilities. During the three and nine months ended September 30, 2019, Quanta recognized net increases of $3.8 million and $8.1 million in the fair value of its aggregate contingent consideration liabilities. These changes are reflected in “Change in fair value of contingent consideration liabilities” in the accompanying condensed consolidated statements of operations. Additionally, Quanta settled certain contingent consideration liabilities with $11.0 million of cash payments and the issuance of 4,277 shares of Quanta common stock during the nine months ended September 30, 2020.
Goodwill and Other Intangible Assets.Assets
As discussed in the Goodwill and Other Intangible Assets sections within this Note 2, Quanta has recorded goodwill and identifiable intangible assets in connection with certain of its historical business acquisitions. Quanta utilizes the fair value premise as the primary basis for its impairment valuation procedures. The Goodwill and Other Intangible Assets sections in Note 2 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data in Part II of the 2020 Annual Report provide information regarding valuation methods, including the income approach, market approach and cost approach, and assumptions used to determine the fair value of these assets based on the appropriateness of each method in relation to the type of asset being valued. Quanta believes that thesethe valuation methods it employs appropriately represent the methods that would be used by other market participants in determining fair value, and periodically engages the services of an independent valuation firm when a new business is acquired to assist management with the valuation process, including assistance with the selection of appropriate valuation methodologies and the development of market-based valuation assumptions. The level of inputs used for these fair value measurements is the lowest level (Level 3).
Investments. Quanta also usesInvestments
Equity investments with readily determinable fair values are measured at fair value, measurementswith changes in connection with the valuation of its investmentsfair value recognized in private company equity interests. These valuations require significant management judgment due to the absence ofnet income. In cases where those readily determinable values are quoted market prices, the inherent lacklevel of liquidity and their long-term nature. Typically, the initial costs ofinput used for 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 recoverable. If an other-than-temporary decline in the value of an investment occurs, a fair value analysismeasurements is performed to determine the degree to which the investment is impaired andhighest level (Level 1). Equity investments without readily determinable fair values are measured on a corresponding charge to earnings is recorded during the period.nonrecurring basis. These types of fair market value assessments are similar to other nonrecurring fair value measures used by Quanta, which include the use of significant judgments 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. The level of inputs used for these fair value measurements is the lowest level (Level 3).
Quanta has investments accounted for using the equity and cost methods of accounting. Quanta utilizes the fair value premise as the basis for its impairment valuation and recognizes impairment if there are sufficient indicators that the fair value of the investment is less than its carrying value.
Financial Instruments.Instruments
The carrying amounts of cash equivalents, accounts receivable, contract assets, accounts payable, and accrued expenses and contract liabilities approximate fair value due to the short-term nature of these instruments. All of Quanta’s cash equivalents were categorized as Level 1 assets at September 30, 20202021 and December 31, 2019,2020, as all values were based on unadjusted quoted prices for identical assets in an active market that Quanta has the ability to access.
Long-term Debt.
The carrying amount of variable rate debt, which includes borrowings under Quanta’s senior credit facility, also approximates fair value. Quanta’s fixed rate debt primarily includes its senior notes. The fair value of Quanta’s 2.900% Senior Notes due October 1, 2030senior notes, which are described further in Note 6, was $1.02$2.52 billion at September 30, 2020.2021, compared to a carrying value of $2.47 billion net of unamortized bond discount, underwriting discounts and deferred financing costs of $28.3 million. The fair value of the senior notes is based on the quoted market prices for the same issue, and the senior notes are categorized as Level 1 liabilities. See Note 76 for additional information regarding Quanta’s senior credit facility and the senior notes.

3. NEW ACCOUNTING PRONOUNCEMENTS:
Adoption of New Accounting Pronouncements
In June 2016, the FASB issued an update for measuring credit losses on most financial assets and certain other instruments that are not measured at fair value through net income. The update amended the impairment model to utilize an expected credit loss methodology in place of the incurred loss methodology for financial instruments, including accounts receivable and contract assets, and off-balance sheet credit exposures. The amendment requires entities to consider a broader range of information to estimate expected credit losses, which often results in earlier recognition of losses. The update also

Quanta adopted the new accounting standard for measuring credit losses effective January 1, 2020 utilizing the transition method that allows recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Quanta’s financial results for reporting periods beginning on or after January 1, 2020 are presented under the new standard, while financial results for prior periods continue to be reported in accordance with the prior standard and Quanta’s historical accounting policy. The net cumulative effect due to the adoption of the new standard was a $3.8 million reduction to retained earnings as of January 1, 2020, which represented a $5.1 million increase to allowance for credit losses, net of $1.2 million in deferred income taxes. The adjustment was based on an estimate of expected lifetime credit losses for financial instruments, primarily accounts receivable and contract assets. Although the adoption of the new standard did not have a material impact on Quanta’s condensed consolidated financial statements at the date of adoption, expected credit losses could change as a result of changes to credit loss experience, specific risk characteristics of Quanta’s portfolio of financial assets or management’s expectations of future economic conditions that affect the collectability of Quanta’s financial assets. Management continues to periodically assess these factors, including any potential effects from the COVID-19 pandemic, and incorporate any changes in its estimate of credit losses.
In August 2018, the FASB issued an update that amends the disclosure requirements related to fair value measurements. Pursuant to this update, certain disclosure requirements will be removed, such as the valuation processes for Level 3 fair value measurements, and other disclosure requirements will be modified or added, including a new requirement to disclose the range and weighted average (or a more reasonable and rational method to reflect the distribution) of significant unobservable inputs used to develop Level 3 fair value measurements. Quanta adopted this guidance effective January 1, 2020, and it did not have a material impact on its condensed consolidated financial statements or disclosures.
Accounting Standards Not Yet Adopted
In December 2019, the FASB issued an update that, among other things, amends the guidance related to accounting for tax law changes when an entity has a year-to-date loss in an interim period and provides guidance on how to evaluate whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This update is effective for interim and annual periods beginning after December 15, 2020, andwith certain amendments should be applied prospectively whileand other amendments should be applied on a modified retrospective basis.

Certain of Quanta’s equipment rental agreements contain purchase options pursuant to which the purchase price is offset by a portion of the rental payments. When rental purchase options are exercised and a substantive benefit is deemed to be transferred to a third-party lessor, the transaction is deemed to be a financing transaction for accounting purposes. This results in the recognition of an asset equal to the purchase price being recorded in “Property, plant and equipment, net of accumulated depreciation,” and the recognition of a corresponding liability in “Current maturities of long-term debt and short-term debt” and “Long-term debt, net of current maturities.” As of September 30, 2020 and December 31, 2019, the assets recorded, net of accumulated depreciation, totaled $23.9 million and $11.8 million.2020.

8. EQUITY:
Exchangeable Shares
In connection with certain prior acquisitions of Canadian businesses, the former owners of the acquired businesses received exchangeable shares of certain Canadian subsidiaries of Quanta, which could be exchanged at the option of the holders for Quanta common stock on a 1-for-one basis. All holders of exchangeable shares had rights equivalent to Quanta common stockholders with respect to dividends and other economic rights. During the nine months ended September 30, 2020 and 2019, a nominal amount and 0.4 million exchangeable shares were exchanged for Quanta common stock, and as of September 30, 2020, 0 exchangeable shares remained outstanding.
Treasury Stock
General. Treasury stock is recorded at cost. Under Delaware law, treasury stock is not counted for quorum purposes or entitled to vote.
Shares withheld for tax withholding obligations. The tax withholding obligations of employees with respect to RSUs and PSUs that are settled in common stock are typically satisfied by Quanta making tax payments and withholding the number of common shares having a value equal to the tax withholding obligation that is due on the date of vesting or settlement (as applicable). With respect to these liabilities, Quanta withheld a nominal amount of Quanta common stock during each of the three months ended September 30, 2020 and 2019, which had a market value of $0.8 million and $0.6 million, and withheld 0.6 million and 0.5 million shares of Quanta common stock during the nine months ended September 30, 2020 and 2019, which had a market value of $24.5 million and $16.7 million. These shares and the related costs to acquire them were accounted for as adjustments to the balance of treasury stock.
Notional amounts recorded related to deferred compensation plans. For RSUs and PSUs that vest but the settlement of which is deferred under a deferred compensation plan, Quanta records a notional amount to “Treasury stock” and an offsetting amount to “Additional paid-in capital” (APIC). At vesting, only shares withheld for tax liabilities other than income taxes are added to outstanding treasury shares, as the shares of Quanta common stock associated with deferred stock-based awards are not issued until settlement of the award. Upon settlement of the deferred stock-based awards and issuance of the associated Quanta common stock, the original accounting entry is reversed. The net amounts recorded to treasury stock related to the deferred compensation plans were NaN and a nominal amount during the three months ended September 30, 2020 and 2019 and $3.6 million and $3.7 million during the nine months ended September 30, 2020 and 2019.

Non-controlling Interests
Quanta holds interests in various entities through both joint venture entities that provide infrastructure-related services under specific customer contracts, either directly or through subcontracting relationships, and other equity investments in partially owned entities that own and operate certain infrastructure assets, including investments entered into through the partnership structure Quanta formed with certain infrastructure investors. Quanta has determined that certain of these joint ventures where Quanta provides the majority of the infrastructure services, which management believes most significantly influences the economic performance of such joint ventures, are VIEs. Management has concluded that Quanta is the primary beneficiary of these joint ventures and has accounted for each on a consolidated basis. The other parties’ equity interests in these joint ventures have been accounted for as “Non-controlling interests” in Quanta’s condensed consolidated balance sheets. Net income attributable to the other participants in the amounts of $0.8 million and $1.0 million for the three months ended September 30, 2020 and 2019 and $4.5 million and $2.6 million for the nine months ended September 30, 2020 and 2019 has been accounted for as a reduction of net income in deriving “Net income attributable to common stock” in Quanta’s condensed consolidated statements of operations.
The carrying amount of the investments in VIEs held by Quanta was $12.0 million and $12.0 million at September 30, 2020 and December 31, 2019. The carrying amount of investments held by the non-controlling interests in these VIEs at September 30, 2020 and December 31, 2019 was $3.6 million and $3.5 million. During the three months ended September 30, 2020 and 2019, net distributions to non-controlling interests were $0.7 million and $0.5 million. During the nine months ended September 30, 2020 and 2019, net distributions to non-controlling interests were $4.7 million and $2.1 million. There were no other material changes in equity as a result of transfers to/from the non-controlling interests during the three and nine months ended September 30, 2020 or 2019.

RSUs to be Settled in Cash
Certain RSUs granted by Quanta 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 stock ownership in Quanta, typically vest in three equal annual installments following the date of grant, and are subject to forfeiture under certain conditions, primarily termination of service. Additionally, subject to certain restrictions, Quanta’s non-employee directors may elect to settle a portion of their RSU awards in cash. For RSUs settled in cash, the holders receive for each vested RSU an amount in cash equal to the fair market value of 1 share of Quanta common stock on the settlement date, as specified in the applicable award agreement.
Compensation expense related to RSUs to be settled in cash was $2.6$13.7 million and $0.8 million for the three months ended September 30, 2020 and 2019 and $5.3 million and $4.5 million for the nine months ended September 30, 20202021 and 2019.2020. Such expense is recorded in “Selling, general and administrative expenses.” RSUs that are anticipated to be settled in cash are not included in the calculation of weighted average shares outstanding for earnings per share, and the estimated earned value of such RSUs is classified as a liability. Quanta paid $0.8$13.2 million and $0.4 million to settle liabilities related to cash-settled RSUs in the three months ended September 30, 2020 and 2019 and $4.3 million and $5.4 million to settle liabilities related to cash-settled RSUs in the nine months ended September 30, 20202021 and 2019.2020. Accrued liabilities for the estimated earned value of outstanding RSUs to be settled in cash were $4.5$7.4 million and $4.3$8.7 million at September 30, 20202021 and December 31, 2019.2020.

11.10. COMMITMENTS AND CONTINGENCIES:
Investments in Affiliates and Other Entities
As described in NotesNote 2, and 9, Quanta holds investments in various entities, including joint venture entities that provide infrastructure-related services under specific customer contracts and partially owned entities that own, operate and/or maintain certain infrastructure assets. LossesAs of September 30, 2021, Quanta had committed to contribute $13.6 million to certain new investments in joint venture entities. The timing of such contributions is not certain, but they are expected to occur in the next twelve months.
If losses are incurred by these entities in which Quanta holds an interest, they are generally shared ratably based on the percentage ownership of the participants in thesethe structures. However, in Quanta’s joint venture structures that provide infrastructure-related services, each participant is typically jointly and severally liable for all of the obligations of the joint venture entity pursuant to the contract with the customer, as a general partner or through a parent guarantee and therefore Quanta can be liable for full performance of the contract with the customer. InAdditionally, in circumstances where Quanta’s participation in a joint venture qualifies as a general

partnership, the joint venture partners are jointly and severallyQuanta can be liable for all 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. Additionally, typically each joint venture participant agrees to indemnify the other participant for any liabilities incurred in excess of what the other participant is obligated to bear under the respective joint venture agreement or in accordance with the scope of work subcontracted to each participant. It is possible, however, that Quanta could be required to pay or perform obligations in excess of its share if another participant is unable or refuses 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. However, to the extent any such claims arise, they could be material and could adversely affect Quanta’s consolidated business, financial condition, results of operations orand cash flows.
As described in Note 2, Quanta formed a partnership in 2017 with select investors to invest in certain specified infrastructure projects, and wholly owned subsidiaries of Quanta serve as the general partner of this partnership and as a separately operated registered investment adviser that manages the invested capital. Quanta’s investment balance related to this partnership was $21.4 million as of September 30, 2020. In October 2019, due to certain management changes at the registered investment adviser, the partnership entered into a 180-day period during which the investors and Quanta evaluated the partnership, and at the end of such period in April 2020, the investment period for any future investments ended.
Contingent Consideration Liabilities
As discussed in further detail in Note 2, Quanta is obligated to pay contingent consideration amounts to the former owners of certain acquired businesses in the event that such acquired businesses achieve specified performance objectives. As of September 30, 2020 and December 31, 2019, the estimated fair value of Quanta’s contingent consideration liabilities totaled $75.8 million and $84.2 million.

times on certain types of vehicles. As of September 30, 2020,2021, Quanta had $55.4$58.5 million of production orders with expected delivery dates in 2020the fourth quarter of 2021 and $16.9$106.9 million of production orders with expected delivery dates in 2021.2022, $68.4 million of which is anticipated to occur in the first half of 2022. Although Quanta has committed to purchase these vehicles at the time of their delivery, Quanta anticipates that the majority of these orders will be assigned to third party leasing companies and made available under certain master equipment lease agreements, thereby releasing Quanta from its capitalequipment purchase commitments.
Legal Proceedings
Quanta is from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, property damage, breach of contract, negligence or gross negligence, and/or property damages,environmental liabilities, wage and hour and other employment-related damages, punitive damages, consequential 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 are expected to have a material adverse effect on Quanta’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’s judgment may prove materially inaccurate, and such judgment is made subject to the known uncertainties of litigation.
Peru Project Dispute.
In 2015, Redes Andinas de Comunicaciones S.R.L. (Redes), a majority-owned subsidiary of Quanta, entered into two separate contracts with an agency of the Peruvian Ministry of Transportation and Communications (MTC), currently Programa Nacional de Telecomunicaciones (PRONATEL), as successor to Fondo de Inversion en Telecomunicaciones (FITEL), pursuant to which Redes would design, construct and operate certain telecommunication networks in rural regions of Peru. The aggregate consideration provided for in the contracts was approximately $248 million, consisting of approximately $151 million to be paid during the construction period and approximately $97 million to be paid during a 10-year post-construction operation and maintenance period. At the beginning of the project, FITEL made advance payments totaling approximately $87 million to Redes, which were secured by two on-demand advance payment bonds posted by Redes to guarantee proper use of the payments in the execution of the project. Redes also provided two on-demand performance bonds in the aggregate amount of $25 million to secure performance of its obligations under the contracts.
During the construction phase, the project experienced numerous challenges and delays, primarily related to issues which Quanta believes were outside of the control of and not attributable to Redes, including, among others, weather-related issues, local opposition to the project, permitting delays, the inability to acquire clear title to certain required parcels of land and other delays which Quanta believes were attributable to FITEL/PRONATEL. In response to various of these challenges and delays, Redes requested and received multiple extensions to certain contractual deadlines and relief from related liquidated damages. However, in April 2019, PRONATEL provided notice to Redes claiming that Redes was in default under the contracts due to the delays and that PRONATEL would terminate the contracts if the alleged defaults were not cured. Redes responded by claiming that it was not in default, as the delays were due to events not attributable to Redes, and therefore PRONATEL was not entitled to terminate the contracts. PRONATEL subsequently terminated the contracts for alleged cause prior to completion of Redes’ scope of work, exercised the on-demand performance bonds and advance payment bonds against Redes, and indicated its intention to claim damages, including a verbal allegation of approximately $45 million of liquidated damages

under the contracts. In August 2020, Redes received a formal claim from PRONATEL for liquidated damages in the amount of approximately $44$38 million, which represents the U.S. dollar equivalent of the amount asserted based on the September 30, 20202021 exchange rate.
In May 2019, Redes filed for arbitration before the Court of International Arbitration of the International Chamber of Commerce (ICC) against PRONATEL and the MTC. In the arbitration, Redes claims that PRONATEL: (i)breached and wrongfully terminated the contracts; (ii) wrongfully executed the advance payment bonds and the performance bonds; and (iii) is not entitled to the alleged amount of liquidated damages. In addition, Redes is seeking compensation for all damages arising from PRONATEL’s actions, including but not limited to (i) repayment of the amounts collected by PRONATEL under the advance payment bonds and the performance bonds; (ii) payment of amounts owed for work completed by Redes under the contracts; (iii) lost income in connection with Redes’ future operation and maintenance of the networks; and (iv) other related costs and damages to Redes as a result of the breach and improper termination of the contracts.contracts (including construction costs caused by the delays and costs related to the transfer of the networks). The amount claimed by Redes in this arbitration is approximately $190 million. In May 2021, PRONATEL and the MTC filed their counter memorial and counterclaims in the ICC arbitration, requesting: (i) that Redes’ claims for breach of contract be rejected; (ii) a declaration that the execution of the advance payment bonds and the performance bonds was valid, and that the funds may be applied towards any debt owed by Redes; (iii) a declaration that the liquidated damages asserted by PRONATEL apply; (iv) that Redes’ claim for payment of amounts owed for work completed as a result of contractual reconciliation of balances be rejected and that any reconciliation of balances approved by the arbitration panel exclude the funds from the performance bonds; (v) that Redes’ claims for damages be rejected; (vi) a declaration that the contract terminations by PRONATEL were valid; and (vii) that Redes reimburse all funds it received from PRONATEL. In addition, PRONATEL alleges that Redes did not satisfy the contractual requirements for the transfer of the networks, which Redes disputes. In July 2021, Redes filed its statement of defense in reply to the counter memorial and counterclaims of PRONATEL and the MTC, in which it disputes all claims made by PRONATEL and the MTC and maintains the positions on its claims against PRONATEL and the MTC in the arbitration. In August 2021, PRONATEL and the MTC filed a rejoinder statement with their position on the merits and damages, which did not present any new claims, and in October 2021, Redes filed a rejoinder with respect to the counterclaims of PRONATEL and the MTC. The arbitration hearing on the merits is presently scheduled to take place in November 2021.
As of the date of the contract terminations, Redes had recognized revenuesincurred costs of approximately $157 million related to the design and construction of the project and had received approximately $100 million of payments (inclusive of the approximately $87 million advance payments). Furthermore, upon completion of the transfer of the networks (as completed at the time of the contract terminations) to PRONATEL, which iswas required upon termination of the contracts and was effectively

completed in the third quarter of 2020, PRONATEL and the MTC are able to possess the networks, for which PRONATEL has paid approximately $100 million while also collecting approximately $112 million of bond proceeds. Quanta believes that PRONATEL’s actions represent an abuse of power and unfair and inequitable treatment and that PRONATEL and the MTC have been unjustly enriched. Specifically, under the terms of the contracts, the advance payment bonds were to be exercised only if it is determined that Redes did not use the advance payments for their intended purpose, in which case Redes would be obligated to return the portion of the advance payments not properly used. In connection with PRONATEL exercising the bonds, Redes was not afforded the opportunity to provide evidence of its proper use of the advance payments for project expenditures. Redes has incurred substantially more than the advance payment amounts in the execution of the project, and Quanta believes Redes has used the advance payment amounts for their intended purpose.
Quanta also reserves the right to seek full compensation for the loss of its investment under other applicable legal regimes, including investment treaties and customary international law, as well as to seek resolution through direct discussions with PRONATEL or the MTC.
Quanta believes Redes is entitled to all amounts described in theits claims above and intends to vigorously pursue those claims in the pending ICC arbitration proceeding and/or additional arbitration proceedings.proceeding. However, as a result of the contract terminations and the inherent uncertainty involved in arbitration proceedings and recovery of amounts owed, there can be no assurance that Redes will prevail on those claims or in defense of liquidated damages claims or any other claims that may be asserted by PRONATEL. As a result, during the three months ended June 30, 2019, Quanta recorded a charge to earnings of $79.2 million, which included a reduction of previously recognized earnings on the project, a reserve against a portion of the project costs incurred through the project termination date, an accrual for a portion of the alleged liquidated damages, and the estimated costs to complete the project turnover and close out the project. The reduction of previously recognized earnings on the project during the three months ended June 30, 2019 included $14.5 million related to the correction of prior period errors associated with the determination of total estimated project costs and the resulting revenue recognized. Quanta assessed the materiality of the prior period errors and determined that the errors were immaterial individually and in the aggregate to its previously issued financial statements.
As of September 30, 2020,2021, after taking into account the above charge, Quanta had a contract receivable of approximately $120 million related to the project, which includes the approximately $87 million PRONATEL collected through exercise of the advance payment bonds. The contract receivable from PRONATEL is included in “Other assets, net” in the accompanying condensed consolidated balance sheet as of September 30, 2020.2021.

Quanta also reserves the right to seek full compensation for the loss of its investment under applicable legal regimes, including investment treaties and customary international law, as well as to seek resolution through direct discussions with PRONATEL or the MTC. In connection with these rights, in May 2020 Quanta’s Dutch subsidiary delivered to the Peruvian government an official notice of dispute arising from the termination of the contracts and related acts by PRONATEL (which are attributable to Peru) under the Agreement on the Encouragement and Reciprocal Protection of Investments between the Kingdom of the Netherlands and the Republic of Peru (Investment Treaty). The Investment Treaty protects Quanta’s subsidiary’s indirect ownership stake in Redes and the project, and provides for rights and remedies distinct from the ICC arbitration. In December 2020, Quanta’s Dutch subsidiary filed a request for the institution of an arbitration proceeding against Peru with the International Centre for Settlement of Investment Disputes (ICSID) related to Peru’s breach of the Investment Treaty, which was registered by ICSID in January 2021. In the ICSID arbitration, Quanta’s Dutch subsidiary claims, without limitation, that Peru: (i) treated the subsidiary’s investment in Redes and the project unfairly and inequitably; and (ii) effectively expropriated the subsidiary’s investment in Redes and the project. In addition, Quanta’s Dutch subsidiary is seeking full compensation for all damages arising from Peru’s actions, including but not limited to (i) the fair market value of the investment and/or lost profits; (ii) attorneys’ fees and arbitration costs; (iii) other related costs and damages and (iv) pre- and post-award interest.
If Quanta is not successful in the pending or future arbitration proceedings, including the ICC arbitration scheduled for November 2021, this matter could result in an additional significant loss that could have a material adverse effect on Quanta’s consolidated results of operations and cash flows. However, based on the information currently available and the preliminary status of the pending arbitration proceeding,proceedings, Quanta is not able to determine a range of reasonably possible additional loss, if any, with respect to this matter.
Maurepas Project Dispute.
During the third quarter of 2017, Maurepas Pipeline, LLC (Maurepas) notified QPS Engineering, LLC (QPS), a subsidiary of Quanta, of its claim for liquidated damages allegedly arising from delay in mechanical completion of a project in Louisiana. Quanta disputes the claim and believes that QPS is not responsible for liquidated damages under the contract terms, and in June 2019 QPS filed suit against SemGroup Corporation (now Energy Transfer LP), the parent company of Maurepas, under the parent guarantee issued to secure payment from Maurepas on the project. QPS is seeking to recover $22 million that it believes has been wrongfully withheld, which represents the maximum liability for liquidated damages pursuant to the contract terms. In July and August 2018, QPS also received notice from Maurepas claiming certain warranty defects on the project. In July 2019, Maurepas filed suit against QPS and Quanta, pursuant to a parent guarantee, for damages related to the alleged warranty defects and for a declaratory judgment related to the liquidated damages claim, subsequently claiming approximately $59 million in damages related to a portion of the alleged warranty defects. The lawsuits relating to these claims have been consolidated and are pending in state courtthe Tulsa County District Court in Oklahoma. Quanta is continuing to evaluate the claimed warranty defects and, if they exist, the appropriate remedy. At this time, Quanta disputes the extent of the alleged defects or has not been able to substantiate them.
As of September 30, 2020,2021, Quanta had recorded an accrual with respect to this matter based on theits current estimated amount of probable loss. However, basedBased on the information currently available, including documentation received in the discovery process, Quanta cannot estimateestimates the range of additional reasonably possible loss in connection with this matter. If, uponmatter is between no additional loss and the amount claimed by Maurepas with respect to the alleged warranty defects and liquidated damages, less the accrued amount. Upon final resolution of this matter, Quanta is unsuccessful, any liquidated damages or warranty defect damages in excess of Quanta’s current loss accrual would be recorded as additional costs on the project.
Lorenzo Benton v. Telecom Network Specialists, Inc., et al.
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

(Unaudited)
Telecom Network Specialists (TNS), a former subsidiary of Quanta. Quanta retained liability associated with this matter pursuant to the terms of Quanta’s sale of TNS in December 2012. Benton represents a class of workers that includes all persons who worked on certain TNS projects, including individuals that TNS retained through numerous staffing agencies. The plaintiff class in this matter is seeking damages for unpaid wages, penalties associated with the failure to provide meal and rest periods and overtime wages, interest and attorneys’ fees. In January 2017, the trial court granted a summary judgment motion filed by the plaintiff class and found that TNS was a joint employer of the class members and that it failed to provide adequate meal and rest breaks and failed to pay overtime wages. During 2019 and 2020, the parties filed additional summary judgment and other motions and a bench trial on liability and damages was held. As of July 2020, liabilityLiability and damages for significantly all claims hadhave been determined by the trial court, with the amount of liability for TNS, determined to be approximately $8.8 million. This amount includes damages andincluding interest thoughthrough the date of the trial court’s orders, but does not include attorneys’ fees or costs, which are yetdetermined to be determined.approximately $9.5 million. Quanta believes the court’s decisions on liability and damages are not supported by controlling law and continues to contest its liability and the damage calculation

QUANTA SERVICES, INC. AND SUBSIDIARIES

(Unaudited)
asserted by the plaintiff class in this matter. The amount determined by the trial court includes damages and interest, but does not include attorneys’ fees or costs. In July 2021, the plaintiff class filed a motion for approval of approximately $37.0 million in attorneys’ fees, and in October 2021, Quanta filed a response to the motion opposing approval of substantially all of the claimed attorneys’ fees.
Additionally, in November 2007, TNS filed cross complaints for indemnity and breach of contract against the staffing agencies, which employed many of the individuals in question. In December 2012, the trial court heard cross-motions for summary judgment filed by TNS and the staffing agencies pertaining to TNS’s demand for indemnity. The court denied TNS’s motion and granted the motions filed by the staffing agencies; however, the California Appellate Court reversed the trial court’s decision in part and instructed the trial court to reconsider its ruling. In February 2017, the court denied a new motion for summary judgment filed by the staffing companies and has since stated that the staffing companies would be liable to TNS for any damages owed to the class members that the staffing companies employed. However, Quanta currently believes that, due to solvency issues, any contribution from the staffing companies may not be substantial.
The final amount of liability, if any, payable in connection with this matter remains the subject of pending litigation and will ultimately depend on various factors, including the outcome of Quanta’s appeal of the trial court’s rulings on liability and damages, thea final determination with respect to any attorneys’ fees or additional costs or damages owed by Quanta, and the solvency of the staffing agencies. Based on review and analysis of the trial court’s rulings on liability, Quanta does not believe, at this time, that it is probable this matter will result in a material loss. However, if Quanta is unsuccessful in this litigation and the staffing agencies are unable to fund damages owed to class members, Quanta believes the range of reasonably possible loss to Quanta upon final resolution of this matter could be up to approximately $8.8$9.5 million, plus additional interest andthe final amount of any attorneys’ fees and expenses ofawarded to the plaintiff class.
Hallen Acquisition Assumed Liability.
In August 2019, in connection with the acquisition of The Hallen Construction Co., Inc. (Hallen), Quanta assumed certain contingent liabilities associated with a March 2014 natural gas-fed explosion and fire in the Manhattan borough of New York City, New York. The incident resulted in, among other things, loss of life, personal injury and the destruction of two2 buildings and other property damage. After investigation, the National Transportation Safety Board determined that the probable cause of the incident was the failure of certain natural gas infrastructure installed by Consolidated Edison, Inc. (Con Ed) and the failure of certain sewer infrastructure maintained by the City of New York. Pursuant to a contract with Con Ed, Hallen had performed certain work related to such natural gas infrastructure and agreed to indemnify Con Ed for certain claims, liabilities and costs associated with its work. Numerous lawsuits are pending in New York state courts related to the incident, which generally name Con Ed, the City of New York and Hallen as defendants. These lawsuits are at various preliminary stages and generally seek unspecified damages and, in some cases, punitive damages, for wrongful death, personal injury, property damage and business interruption.
As of September 30, 2021, Quanta had not recorded an accrual related to this matter. Hallen’s liabilities associated with this matter are expected to be covered under applicable insurance policies or contractual remedies negotiated by Quanta with the former owners of Hallen. As of September 30, 2020, Quanta had not recorded an accrual for anyIf a loss becomes probable and estimable loss relatedwith respect to this matter.matter, Quanta expects to accrue its estimated liability and a receivable in the same amount. However, the ultimate amount of liability in connection with this matter remains subject to uncertainties associated with pending litigation, including, among other things, the apportionment of liability among the defendants and other responsible parties and the likelihood and amount of potential damages claims. As a result, this matter could result in a loss that is in excess of, or not covered by, such insurance or contractual remedies, which could have a material adverse effect on Quanta’s consolidated financial condition, results of operations and cash flows.
Concentrations of Credit Risk
Quanta is subject to concentrations of credit risk related primarily to its cash and cash equivalents and its net receivable position with customers, which includes amounts related to billed and unbilled accounts receivable and contract assets net of advanced billings with the same customer. Substantially all of Quanta’s cash and cash equivalents are managed by what it believes to be high credit quality financial institutions. In accordance with Quanta’s investment policies, these institutions are authorized to invest cash and cash equivalents in a diversified portfolio of what Quanta believes to be high quality cash and cash equivalent investments, which consist primarily of interest-bearing demand deposits, money market investments and money market mutual funds. Although Quanta does not currently believe the principal amount of these cash and cash

equivalents is subject to any material risk of loss, changes in economic conditions could impact the interest income Quanta receives from these investments. In addition, Quanta grants credit under normal payment terms, generally without collateral, to its customers, which include electric power, communications and energy companies, governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States, Canada and

Australia. While Quanta generally has certain statutory lien rights with respect to services provided, Quanta is subject to potential credit risk related to business, economic and financial market conditions that affect these customers and locations, which has been heightened as a result of the unfavorable and uncertain economic and financial market conditions resulting from the ongoing COVID-19 pandemic and the significant decline in commodity prices and volatility in commodity production volumes.currently challenged energy market. Some of Quanta’s customers have experienced significant financial difficulties (including bankruptcy), and customers may experience financial difficulties in the future. These difficulties expose Quanta to increased risk related to collectability of billed and unbilled receivables and contract assets for services Quanta has performed.
For example, a customer within Quanta’s Underground Utility and Infrastructure Solutions segment encountered financial difficulties during 2020 that resulted in nonpayment of $27.5 million of receivables, plus accrued interest. As a result of the nonpayment, Quanta decided to foreclose the liens on January 29, 2019, PG&E Corporationthe pipeline asset in order to recover the outstanding amount. During the three months ended September 30, 2021, Quanta entered into a settlement with the customer resulting in the sale of the pipeline asset to a third party and its primary operating subsidiary, Pacific Gaspursuant to which Quanta received $10.0 million of the amount owed and Electric Company (together, PG&E), onethe right to receive payment of the remainder of the receivables in quarterly installments from the third party based on the cash flows generated by the pipeline and certain related assets. As a result, the remaining receivable balance of $17.5 million was reclassified to long-term receivables at September 30, 2021. Quanta also retained a security interest in the pipeline asset to secure payment of the remaining amount owed and believes that the value of the pipeline asset is in excess of such amount. However, the ultimate outcome with respect to the amount owed remains uncertain and is based on a number of assumptions that are potentially subject to change, including the future financial performance of the third party and the cash flows generated by the pipeline asset, as well as the future value of the pipeline asset. As a result, the amount ultimately collected could be materially less than the amount owed.
Additionally, in July 2021 Limetree Refining, a customer within Quanta’s largest customers,Underground Utility and Infrastructure Solutions segment, filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, as amended. As of the bankruptcy filing date, Quanta had $165 million of billedamended, after experiencing operational and unbilled receivables. During the bankruptcy case, the bankruptcy court approved the early assumption by PG&E of certain contracts with subsidiaries of Quanta,financial difficulties and PG&E subsequently assumedshutting down operations at its remaining contracts with Quanta’s subsidiaries as part of its Chapter 11 plan of reorganization, which was confirmed by the bankruptcy court in June 2020. As of September 30, 2020, substantially all of Quanta’s pre-petition receivables had been paid. Additionally, a customer within Quanta’s Pipeline and Industrial Infrastructure Services segment is currently experiencing liquidity challenges that have resulted in delayed payment of certain receivables associated with a project. While Quanta believes these receivables are adequately secured by the project asset, Quanta is continuing to monitor potential credit risk with respectrefinery. See Note 2 for further information related to this and other customers.customer.
At September 30, 2020 and2021, the net receivable position of 1 customer within Quanta’s Electric Power Infrastructure Solutions segment, when combined with the net receivable position of a joint venture in which such customer owns a 50% interest, represented 12% of Quanta’s consolidated net receivable position. At December 31, 2019, 02020, no customer represented 10% or more of Quanta’s consolidated net receivable position. NaNNo customer represented 10% or more of Quanta’s consolidated revenues for the three and nine months ended September 30, 20202021 or 2020.
Insurance
Quanta is insured for, among other things, employer’s liability, workers’ compensation, auto liability, aviation and general liability claims. Quanta manages and maintains a portion of its casualty risk through its wholly-owned captive insurance company, which insures all claims up to the three months endedamount of the applicable deductible of its third-party insurance programs. Deductibles for the employer’s liability and workers’ compensation programs are $5.0 million per occurrence, and deductibles for the auto liability and general liability programs are $15.0 million per occurrence. Quanta also has employee health care benefit plans for most employees not subject to collective bargaining agreements, of which the primary plan is subject to a deductible of $0.8 million per claimant per year.
As of September 30, 2019. PG&E, a customer within Quanta’s Electric Power Infrastructure Services segment, represented 10.5% of Quanta’s consolidated revenues for2021 and December 31, 2020, the nine months ended September 30, 2019.
Insurance
As discussed in Note 2, Quanta is insuredgross amount accrued for employer’s liability, workers’ compensation, auto liability, general liability, and group health claims. As of September 30, 2020 and December 31, 2019, the gross amount accrued for insurance claims totaled $304.6$316.8 million and $287.6$319.5 million, with $223.6$232.8 million and $212.9$238.0 million considered to be long-term and included in “Insurance and other non-current liabilities.” Related insurance recoveries/receivables as of September 30, 20202021 and December 31, 20192020 were $31.8$26.1 million and $35.1$35.6 million, of which $0.3$0.4 million and $0.3$0.4 million are included in “Prepaid expenses and other current assets” and $31.5$25.7 million and $34.8$35.2 million are included in “Other assets, net.”
Quanta renews its insurance policies on an annual basis, and therefore deductibles and levels of insurance coverage may change in future periods. In addition, insurers may cancel Quanta’s coverage or determine to exclude certain items from coverage, including wildfires, or Quanta may elect not to obtain certain types or incremental levels of insurance based on the potential benefits considered relative to the cost of such insurance, or coverage may not be available at reasonable and competitive rates. In any such event, Quanta’s overall risk exposure would increase, which could negatively affect its results of operations, financial condition and cash flows. For example, due to the increased occurrence and future risk of wildfires in California and other areas in the western United States, Australia and other locations, insurers have reduced coverage availability and increased the cost of insurance coverage for such events in recent years. As a result, Quanta’s level of insurance coverage for wildfire events has decreased, including in connection with recent annual insurance renewals, and the current level
36

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)
of coverage may not be sufficient to cover potential losses in connection with these events. Additionally, Quanta’s third-party insurers could decide to further reduce, exclude or increase the cost of coverage for wildfires or other events in connection with insurance renewals in the future.
Letters of Credit
Certain of Quanta’s vendors require letters of credit to ensure reimbursement for amounts they are disbursing on Quanta’s behalf, such as to beneficiaries under its insurance programs. In addition, from time to time, certain customers require Quanta to post letters of credit to ensure payment of subcontractors and vendors and guarantee performance under contracts. Such letters of credit are generally issued by a bank or similar financial institution, typically pursuant to Quanta’s senior credit facility. Each letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit if the holder claims 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.
As of September 30, 2020,2021, Quanta had $364.5$333.9 million in outstanding letters of credit under its senior credit facility securing its casualty insurance program and various other contractual commitments. These are irrevocable stand-by letters of credit with maturities generally expiring at various times throughout 20202021 and 2021.2022. Quanta expects to renew the majority of the letters of credit related to the casualty insurance program for subsequent one-year periods upon their maturity. As of September 30, 2020, Quanta also had $91.9 million letters of credit issued by a financial institution that ceased to be a lender under the senior credit facility subsequent to the September 2020 amendment to the credit agreement, and such letters of credit are collateralized by a $93.0 million letter of credit issued by a lender in the senior credit facility. Quanta is not aware of any claims currently asserted or threatened under any of these letters of credit that are material, individually or in the aggregate. However, to the extent payment is required for any such claims, the amount paid could be material and could adversely affect Quanta’s consolidated business, financial condition, results of operations orand cash flows.

Bonds and Parent Guarantees
Many customers, particularly in connection with new construction, require Quanta to post performance and payment bonds. These bonds provide a guarantee that Quanta will perform under the terms of a contract and pay its subcontractors and vendors. If Quanta fails to perform,In certain circumstances, the customer may demand that the surety make payments or provide services under the bond, and Quanta must reimburse the surety for any expenses or outlays it incurs. Quanta may also be required to post letters of credit in favor of the sureties, which would reduce the borrowing availability under its senior credit facility. Under Quanta’s underwriting, continuing indemnity and security agreement with its sureties, Quanta had also granted security interests in certain of its assets as collateral for its obligations to the sureties. However, in connection with the September 2020 amendment to the credit agreement, these security interests were automatically released. On September 22, 2020, Quanta also entered into an amendment to the underwriting, continuing indemnity and security agreement that further documented this release and removed the collateral reinstatement provision in the agreement that would have applied in the event Quanta's corporate credit rating from either of Moody’s Investors Service, Inc. or Standard & Poor’s Financial Services LLC were to fall below an investment grade rating.
Quanta has not been required to make any material reimbursements to its sureties for bond-related costs except related toin connection with the exercise of certainapproximately $112 million advance payment and performance bonds in connection with2019 related to the terminated telecommunications project located in Peru, as set forth in Legal Proceedings - Peru Project Dispute above. However, to the extent further reimbursements are required, the amounts could be material and could adversely affect Quanta’s consolidated business, financial condition, results of operations orand cash flows. As of September 30, 2021, Quanta is not aware of any outstanding material obligations for payments related to bond obligations.
Performance bonds expire at various times ranging from mechanical completion of a project to a period extending beyond contract completion in certain circumstances, and as suchtherefore 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’s bonded operating activity. As of September 30, 2020,2021, the total amount of the outstanding performance bonds was estimated to be approximately $3.5$3.8 billion. Quanta’s estimated maximum exposure as it relatesrelated to the value of the performance bonds outstanding is lowered on each bonded project as the cost to complete is reduced, and each commitment under a performance bond generally extinguishes concurrently with the expiration of its related contractual obligation. The estimated cost to complete these bonded projects was approximately $1.4$1.1 billion as of September 30, 2020.2021.
Additionally, from time to time, Quanta guarantees certain obligations and liabilities of its subsidiaries that may arise in connection with, among other things, contracts with customers, equipment lease obligations, joint venture arrangements and contractor licenses. These guarantees may cover all of the subsidiary’s unperformed, undischarged and unreleased obligations and liabilities under or in connection with the relevant agreement. For example, with respect to customer contracts, a guarantee may cover a variety of obligations and liabilities arising during the ordinary course of the subsidiary’s business or operations, including, among other things, warranty and breach of contract claims, third party and environmental liabilities arising from the subsidiary’s work and for which it is responsible, liquidated damages, or indemnity claims. Quanta is not aware of any claims under any of these guarantees that are material, except as set forth in Legal Proceedings – Maurepas Project Dispute above. To the extent a subsidiary incurs a material obligation or liability and Quanta has guaranteed the performance or payment of such obligation or liability, the recovery by a customer or other counterparty or a third party will not be limited to the assets of the subsidiary. As a result, responsibility under the guarantee could exceed the amount recoverable from the subsidiary alone and could materially and adversely affect Quanta’s consolidated business, financial condition, results of operations and cash flows.
Employment Agreements
37

QUANTA SERVICES, INC. AND SUBSIDIARIES
Quanta has various employment agreements with certain executives and other employees, which provide for compensation, other benefits and, under certain circumstances, severance payments and post-termination stock-based compensation benefits. Certain employment agreements also contain clauses that require the potential payment of specified amounts to such employees upon the occurrence of a defined change in control event.NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)
Collective Bargaining Agreements and Multiemployer Pension Plans
Certain of Quanta’s operating units are parties to 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 and arbitration 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 union employees and contribute certain amounts to multiemployer pension plans and employee benefit trusts. Quanta’s multiemployer pension plan contribution rates generally are made to the plans on a “pay-as-you-go” 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 Quanta’s need for union resources in connection

with its ongoing projects. Therefore, Quanta is unable to accurately predict its union employee payroll and the resulting multiemployer pension plan contribution obligations for future periods.
The Pension Protection Act of 2006 also added special fundingmay require Quanta to make additional contributions to its multiemployer pension plans if they become underfunded, and operational rules generally applicable to plan years beginning after 2007 for multiemployer plans that are classified as “endangered,” “seriously endangered” or “critical” statusthese additional contributions will be determined based on multiple factors (including, for example,Quanta’s union employee payrolls. Certain plans to which Quanta contributes or may contribute in the plan’s funded percentage, the plan’s cash flow position and whether the plan is projected to experience a minimum funding deficiency). Plans in these classifications mustfuture may adopt measures to improve their funded status through a funding improvement or rehabilitation plan, as applicable, which may require additional contributions from employers (e.g., 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 “endangered,” “seriously endangered” or “critical” status. The amount, if any, that Quanta may be obligated to contribute to these plans cannot be reasonably estimated due to uncertainty regarding the amount of future work involving covered union employees, future contribution levels and possible surcharges on plan contributions.
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 certainThese liabilities upon an employer who is a contributor to a multiemployer pension plan if the employer withdraws or is deemed to have withdrawn from the plan or the plan is terminated or experiences a mass withdrawal. These liabilitiesmay include an allocable share of the unfunded vested benefits in the plan for all plan participants, not merelyonly the benefits payable to a contributing employer’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. Quanta is not aware of any material withdrawal liabilities that have been incurred or asserted and that remain outstanding as a result of a withdrawal by Quanta from a multiemployer defined benefit pension plan. However, Quanta’s future contribution obligations and potential withdrawal liability exposure could vary based on the investment and actuarial performance of the multiemployer pension plans to which it contributes and other factors, which could be negatively impacted as a result of the unfavorable and uncertain economic and financial market conditions resulting from the ongoing COVID-19 pandemic and related issues. Quanta has been subject to significant withdrawal liabilities in the past, including in connection with its withdrawal from the Central States, Southeast and Southwest Areas Pension Plan. To the extent Quanta is subject to material withdrawal liabilities in the future, such liability could adversely affect its business, financial condition, results of operations orand cash flows.
Deferred Compensation Plans
Quanta maintains nonqualifiedmade matching contributions to the eligible participants’ accounts under deferred compensation plans pursuant to which non-employee directorsof $0.2 million during each the three months ended September 30, 2021 and certain key employees may defer receipt of some or all of their cash compensation and/or settlement of certain stock-based awards, subject to certain limitations. These plans are unfunded and unsecured compensation arrangements. Individuals participating in these plans may allocate deferred cash amounts among a group of notional accounts that mirror the gains and losses of various investment alternatives. Generally, participants receive distributions of deferred balances based on predetermined payout schedules or other events.
The plan covering key employees provides for employer matching contributions for certain officers and employees whose benefits under the 401(k) plan are limited by federal tax law. Quanta may also make discretionary employer contributions to such plan. Matching contributions vest immediately, and discretionary employer contributions may be subject to a vesting schedule determined at the time of the contribution, provided that vesting accelerates upon a change in control or the participant’s death or retirement. All matching and discretionary employer contributions, whether vested or not, are forfeited upon a participant’s termination of employment for cause or upon the participant engaging in competition with Quanta or any of its affiliates. 
2020. Quanta made matching contributions to the eligible participants’ accounts under the deferred compensation plans of $0.2$1.0 million during each of the three months ended September 30, 2020 and 2019 and $1.0 million and $0.9 million during the nine months ended September 30, 20202021 and 2019.2020. Quanta made 0no discretionary contributions during the nine months ended September 30, 20202021 and 2019.2020. At September 30, 20202021 and December 31, 2019,2020, obligations under these plans, including amounts contributed by Quanta, were $51.4$69.1 million and $47.3$58.2 million, andthe majority of which were included in “Insurance and other non-current liabilities” in the accompanying condensed consolidated balance sheets. Quanta maintains investments to provide forcontribute to future obligations related to these deferred compensation plans. At September 30, 20202021 and December 31, 2019,2020, these investments were primarily comprised of company-owned life insurance policies, had fair market values of $52.2$68.4 million and $45.8$56.5 million and were included in “Other assets, net” in the accompanying condensed consolidated balance sheets.
During the three months ended September 30, 2021 and 2020, the fair market value of assets associated with our deferred compensation plan decreased $0.2 million and increased $2.8 million. During the nine months ended September 30, 2021 and 2020, the fair market value of assets associated with our deferred compensation plan increased $5.3 million and $1.9 million. These changes in fair market value of the assets are recorded in “Other income (expense), net” and were largely offset by corresponding changes in the fair market value of the liabilities associated with our deferred compensation plan, which are recorded in “Selling, general and administrative expenses.” During the three months ended September 30, 2021 and 2020, the fair market value of deferred compensation liabilities did not change and increased $3.3 million. During the nine months ended September 30, 2021 and 2020, the fair market value of deferred compensation liabilities increased $6.0 million and $1.9 million.

Indemnities
Quanta generally indemnifies its customers for the services it provides under its contracts and 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. Quanta is not aware of any indemnity claims in connection with its indemnity obligations that are material. However, to the extent indemnification is required, the amount could adversely affect Quanta’s consolidated business, financial condition, results of operations orand cash flows.
In the normal course of Quanta’s acquisition transactions, Quanta obtains rights to indemnification from the sellers or former owners of acquired businesses for certain risks, liabilities and obligations arising from their operations prior operations,to the date of acquisition, 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’s exposure for such pre-acquisition matters, or the indemnitors may be unwilling or unable to pay amounts owed to Quanta. Accordingly, Quanta may incur expenses for which it is not reimbursed, and such amounts could be material and could have a material adverse effect on Quanta’s business or consolidated financial condition, results of operations and cash flows. For example, Quanta has obtained certain indemnification rights from the former owners of Hallen with respect to contingent liabilities that were assumed in connection with the acquisition, as set forth in Legal Proceedings — Hallen Acquisition Assumed Liability above.
Residual Value Guarantees
12.Quanta has also guaranteed the residual value under certain of its equipment operating leases, agreeing to pay any difference between this residual value and the fair market value of the underlying asset at the date of lease termination. As of September 30, 2021, the maximum guaranteed residual value of this equipment was $886.9 million. While Quanta believes that no significant payments will be made as a result of these residual value guarantees, there can be no assurance that significant payments will not be required in the future.
Deferral of Employer Payroll Taxes
During 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act), which provided for various tax relief and tax incentive measures. These measures did not have a material impact on Quanta’s results of operations. However, pursuant to the CARES Act, Quanta deferred the payment of $108.9 million of employer payroll taxes during the year ended December 31, 2020, 50% of which are due to be paid by December 31, 2021 and the remainder is due by December 31, 2022.

11. SEGMENT INFORMATION:
Quanta currently presents its operations under 2 reportable segments: (1) Electric Power Infrastructure ServicesSolutions and (2) PipelineUnderground Utility and Industrial Infrastructure Services.Solutions. This structure is generally based on the broad end-user markets for Quanta’s services. See Note 1 for additional information regarding Quanta’s reportable segments.
Quanta’s segment results are derived from the types of services provided across its operating units in each of its end user markets. Quanta’s entrepreneurial business model allows multiple operating units to serve the same or similar customers and to provide a range of services across end user markets. Quanta’s operating units are organized into one of 2 internal divisions: the Electric Power Infrastructure ServicesSolutions Division and the PipelineUnderground Utility and Industrial Infrastructure ServicesSolutions Division. These internal divisions are closely aligned with the reportable segments, and operating units are assigned to divisions based on the predominant type of work performed.
Reportable segment information, including revenues and operating income by type of work, is gathered from each operating unit for the purpose of evaluating segment performance in support of Quanta’s market strategies. Classification of operating unit revenues by type of work for segment reporting purposes can require judgment on the part of management. Quanta’s operating units may perform joint projects for customers in multiple industries, deliver multiple types of services under a single customer contract or provide service offerings to various industries. For example, Quanta performs joint trenching projects to install distribution lines for electric power and natural gas customers.
In addition, Quanta’s integrated operations and common administrative support for its operating units require that certain allocations be made to determine segment profitability, including allocations of shared and indirect costs (e.g., facility costs), indirect operating expenses (e.g., depreciation), and general and administrative costs. Certain corporate costs are not allocated

13. SUBSEQUENT EVENTS:
On October 13, 2021, Quanta completed the acquisition of Blattner, a large utility-scale renewable energy infrastructure solutions provider located in North America. The consideration for this transaction, which remains subject to certain post-closing adjustments, consisted of approximately $2.29 billion paid in cash on the date of acquisition and 3.3 million shares of Quanta common stock, which had a fair value of $345.4 million as of the date of the acquisition. See Note 1 and Note 4 for additional information on Blattner and Quanta’s acquisition of Blattner. Additionally, on October 8, 2021, Quanta amended its senior credit facility to, among other things, provide for a new $750.0 million term loan facility, increase the aggregate revolving commitments from $2.51 billion to $2.64 billion and extend the maturity date for the revolving commitments from September 2025 to October 2026. Quanta used proceeds from the new term loan, together with the net proceeds from its offering of senior notes in September 2021 and revolving loans borrowed under the senior credit facility, to finance the cash portion of the consideration paid in connection with the acquisition of Blattner. See Note 6 for additional information regarding the amendment to Quanta’s senior credit facility.
In October 2021, Quanta also acquired (i) a 44% interest in an entity that will be accounted for as an integral affiliate using the equity method of accounting and (ii) a business located in the United States that provides electric power construction and related services.

The final amount of consideration for this acquisition remains subject to certain post-closing adjustments, including with respect to net working capital. Additionally, we entered into an amendmentpursuant to the credit agreement for our senior credit facility (the credit agreement) that, among other things, increased the aggregate revolving commitments from $2.14 billion to $2.51 billion, extended the maturity date from October 31, 2022 to September 22, 2025, released the liens on the collateral securing our obligations thereunder, released the subsidiary guarantors from their guarantees of such obligations and removed the collateral reinstatement provision that would have applied in the event our corporate credit rating were to fall below an investment grade rating. See Liquidity and Capital Resources – Debt Instruments for additional information on the senior notes issuance and the amendment to our credit agreement.
Recent Acquisitions and Investments
We continue to selectively evaluate acquisitions as part of our overall business strategy and acquired five businesses in the nine months ended September 30, 2020, including an industrial services business located in Canada that performs catalyst handling services, including changeover and shutdown maintenance, for customers in the refining and chemical industries; an electric power infrastructure business located in the United States that primarily provides underground conduit services; a professional engineering business located in the United States that provides infrastructure engineering and design services to electric utilities, gas utilities and communications services companies, as well as permitting and utility locating services; a contractor located in the United States that provides electric power distribution, transmission and substation maintenance and construction, directional boring and emergency restoration services; and a business located in the United States that specializes in the deployment of short- and long-haul fiber optic cable and utilities. During the three and nine months ended September 30, 2020, revenues were positively impacted by approximately $135 million and $325 million from acquired businesses. Beginning on the respective acquisition dates, the resultsterms of the agreement and plan of merger, the former Blattner owners are eligible for the potential payment of up to $300 million of contingent consideration, payable to the extent the acquired businesses have beenbusiness achieves certain financial performance targets over a three-year period beginning in January 2022.

During the nine months ended September 30, 2020, a joint venture in which we own a 50% interest, LUMA Energy, LLC (LUMA), was selected for a 15-year operation and maintenance agreement to operate, maintain and modernize the approximately 18,000-mile electric transmission and distribution system in Puerto Rico. The 15-year operation and maintenance period is expected to begin following an approximately one-year transition period, during which LUMA will complete numerous steps necessary to transition operation and maintenance from the current operator to LUMA. During the transition period, LUMA receives a fixed transition services fee, payable in monthly installments, and is reimbursed for costs and expenses. During the operation and maintenance period, LUMA will continue to be reimbursed for costs and expensesfair value assessment of contingent consideration, and will receive a fixed annual management fee, withinclude the opportunity to receive additional annual performance-based incentive fees. LUMA will not assume ownership of any electric transmission and distribution system assets and will not be responsible for operation of the power generation assets.
COVID-19 Pandemic Response and Impact
During 2020, the COVID-19 pandemic has significantly impacted global economies, resulting in workforce and travel restrictions, supply chain and production disruptions and reduced demand and spending across many sectors. These factors have had, and continue to have, an adverse impact on portions of our operations, financial performance, customers and suppliers. However, we continue to operate substantially all of our activities as a provider of essential servicespreliminary purchase price allocation in our industries. Additionally, we are continuing to collaborate with customers to minimize potential service disruptions and anticipate how the COVID-19 pandemic may continue to impact our operations, as the locations where we, our customers, our suppliers or our third-party business partners operate continue to experience challenges as a result of the pandemic. We have also taken proactive measures to protect the health and safety of our employees, such as the adoption of specialized training initiatives and the utilization of additional protective equipmentAnnual Report on Form 10-K for our employees operating in the field and additional sanitation measures for our offices, vehicles and equipment. We have also reduced non-essential business travel, applied work-from-home policies where appropriate and developed other human resource guidance to help employees.
Our results have been adversely impacted by the COVID-19 pandemic as a result of disruptions in our operations created by shelter-in-place restrictions in certain service areas, primarily during the first and second quarters of 2020 and in major metropolitan markets that have been meaningfully impacted by the pandemic, such as New York City, Detroit and Seattle. While the significant adverse impacts resulting from these shelter-in-place restrictions in major U.S. metropolitan markets subsided in the third quarter of 2020, the possibility of future restrictions remains. The COVID-19 pandemic has also compounded broader challenges in the energy market, resulting in a decline in commodity prices and volatility with respect to commodity production volumes that are affecting portions of our Pipeline and Industrial Infrastructure Services segment. As expected, this dynamic had a materially negative impact on segment results for the three and nine months ended September 30, 2020. In particular, demand for our industrial services operations has declined as customers are reducing and deferring regularly scheduled maintenance due to lack of demand for refined products. Additionally, smaller pipeline and industrial capital projects are expected to be negatively impacted for a prolonged period due to the low commodity price environment and resulting reductions in customer capital budgets. We are also experiencing some permitting and regulatory delays for projects due to the COVID-19 pandemic, and the pandemic has negatively impacted our Latin American operations due to shelter-in-place restrictions and other work disruptions. Furthermore, while we are not currently experiencing significant supply chain disruptions or workforce availability concerns, we are continuing to monitor these areas for potential issues.
Additionally, we are focused on maintaining a strong balance sheet to help us navigate the challenges presented by the COVID-19 pandemic. As of September 30, 2020, we had $216.9 million of cash and cash equivalents and, as a result of the amendment entered into during September 2020, had $1.95 billion of availability under our senior credit facility. We generated $114.9 million and $839.9 million of cash flow from operating activities in the three and nine months ended September 30, 2020 and $526.6 million in cash flow from operations in the year ended December 31, 2019. We are managing our costs through, among other things, reductions in discretionary spending, reductions in workforce at operations experiencing challenges, hiring and compensation increase deferrals, and deferrals of non-essential capital expenditures. Capital expenditures for 2020 are expected to be $250 million, which is approximately 17% less than our original estimate at the beginning of 2020. We will continue to maintain capital discipline and monitor rapidly changing market dynamics and adjust our costs and financing strategies accordingly.2021.
As a result of the currently challenged energy market and recent oil price volatility, as well as the exacerbating effect of the COVID-19 pandemic, we assessed the expected negative impacts related to goodwill, intangible assets, long-lived assets, and investments as of September 30, 2020. We concluded that other than $18.0 million of impairments recognized during the first and second quarters of 2020, as described further in Results of Operations below, the impacts are not likely to result in any other impairments of such assets at this time. However, the potential impacts are uncertain and may change based on numerous
52


factors. We will continue to monitor the impacts and should a reporting unit or investment suffer additional significant declines in actual or forecasted financial results, the risk of impairment would increase.
On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act). The CARES Act provides for various tax relief and tax incentive measures, which are not expected to have a material impact on our results of operations. During the three and nine months ended September 30, 2020, under the CARES Act, we deferred the payment of $41.0 million and $72.2 million of payroll taxes, 50% of which are due by December 31, 2021 and the remainder of which are due by December 31, 2022. The CARES Act permits deferral of payroll taxes through December 31, 2020, and we currently intend to continue to defer such payments.
The broader and longer-term implications of the COVID-19 pandemic on our results of operations and overall financial performance and position remain highly uncertain, and we expect continued operational challenges through at least the balance of the year and into 2021 as we operate during and adjust to an unprecedented health and economic environment. Therefore, we cannot predict the full impact that the pandemic, or any resulting market disruption and volatility, will have on our business, cash flows, liquidity, financial condition and results of operations at this time. The ultimate impact will depend on future developments, including, among others, the ongoing spread of COVID-19, the consequences of governmental and other measures designed to prevent the spread of COVID-19, the development and availability of effective treatments and vaccines, the duration and severity of the pandemic, actions taken by governmental authorities, customers, suppliers and other third parties, workforce availability, and the timing and extent to which normal economic and operating conditions resume and continue. For additional discussion regarding risks associated with the COVID-19 pandemic, see Item 1A. Risk Factors of Part II of this Quarterly Report.
Business Environment
Despite the current challenging economic conditions, weWe believe there are long-term growth opportunities across our industries, and we continue to have a positive long-term outlook. Although not without risks and challenges, including those discussed in Overview and in Cautionary Statement About Forward-Looking Statements and Information,and included in Item 1A. Risk Factors, of Part II of this Quarterly Report and Item 1A. Risk Factors of Part I of our 2020 Annual Report, we believe, with our full-service operations, broad geographic reach, financial position and technical expertise, we are well positioned to capitalize on opportunities and trends in our industries.
Electric Power Infrastructure Services SegmentSolutions. Utilities are investing significant capital in their electric power delivery systems, particularly transmission, substation and distribution infrastructure, through multi-year, multi-billion dollar grid modernization and reliability programs, which have provided, and are expected to continue to provide, demand for our services. UtilitiesAs the overall
44

electrification trends in North America support a transition toward a carbon-neutral economy, utilities are accommodating a changing fuel generation mix that is moving toward more sustainable sources such as renewables (e.g., wind, solar and battery storage) and natural gas and renewables and replacing aging infrastructure to support long-term economic growth. We believe this trend will generate significant demand in the near- and longer-term for our services, including the development and construction of generation facilities powered by renewable energy sources (e.g., wind and solar) and certain traditional energy sources (e.g., natural gas), the development and construction of related infrastructure (e.g., battery storage), and the modernization of existing assets. While the demand for certain renewable energy services is expected to fluctuate in the short term due to, among other things, supply chain and other logistical difficulties that could delay projects, production tax credits and sourcing restrictions on materials necessary for certain projects (e.g., solar panels), we believe our recent acquisition of Blattner, together with the renewable energy and related services performed by our other operating companies, positions us to capitalize on the longer term growth trends with respect to the development of wind, solar and storage capacity infrastructure.
Furthermore, while the COVID-19 pandemic resulted in a short-term overall decline in electricity usage in 2020, primarily related to commercial and industrial users, demand has recovered and continues to increase in 2021, and we expect demand for electricity in North America to grow over the long term and believe that certain segments of the North American electric power grid are not adequate to efficiently serve the power needs of the future. To the extent that electrification trends increase, including through electric vehicle (EV) adoption, demand for electricity could be greater than currently anticipated. To accommodate this growth, we expect continued demand for new or expanded transmission and substation infrastructure to reliably transport power and interconnect new generation facilities and the modification and reengineering of existing infrastructure as existing coal and nuclear generation facilities are retired or shut down.
In order to reliably and efficiently deliver power, and in response to federal reliability standards, utilities are also integrating smart grid technologies into distribution systems in order to improve grid management and create efficiencies, and in preparation for emerging technologies such as electric vehicles.EVs. A number of utilities are also implementinghave and continue to implement system upgrades or hardening programs in response to recurring severe weather events, such as hurricanes and wildfires. Inwildfires, and, in particular, currentthere are significant system resiliency initiatives in California and other regions in the western U.S. underway that are designed to prevent and manage the impact of wildfires. However, while theseThese resiliency initiatives provide additional opportunities for our services,services; however, they also increase our potential exposure to significant liabilities attributable to those events.
While the COVID-19 pandemic has resulted Utilities are also executing significant initiatives to underground critical infrastructure, including additional underground transmission and distribution initiatives by utilities in an overall decline in electricity usageCalifornia, underground electric transmission projects in the near term, primarily related to commercialnortheast, underground distribution circuits along the coastlines and industrial users, we expect demandunderground transmission lines for electricity in North America to grow over the long term and believe that certain segments of the North American electric power grid are not adequate to efficiently serve the power needs of the future. As demand for power increases, we also expect an increase in new poweroffshore wind generation facilities powered by certain traditional energy sources (e.g., natural gas) and renewable energy sources (e.g., solar and wind). To the extent this dynamic continues, we expect continued demand for new or expanded transmission and substation infrastructure to transport power and interconnect new generation facilities and the modification and reengineering of existing infrastructure as existing coal and nuclear generation facilities are retired or shut down.projects.
With respect to our communications service offerings, consumer and commercial demand for communication and data-intensive, high-bandwidth wireline and wireless services and applications is driving significant investment in infrastructure and the deployment of new technologies. In particular, communications providers in North America are in the early stages of developing new fifth generation wireless services (5G), which are intended to facilitate bandwidth-intensive services at high speeds for consumers and a wide rangecommercial applications. Additionally, the Federal Communications Commission has enacted the Rural Digital Opportunity Fund for the purpose of commercial applications.deploying billions of dollars in federal funds for high speed fixed broadband service to underserved rural homes and small businesses. As a result of these industry trends, we believe there will be meaningful demand for our services in that market. While we continueengineering and construction services. We also reoriented our communications service offerings to perform certain electric power and communications services in Latin America, we have completed a strategic review of those operations, and due to circumstances experienced in connection with a terminated telecommunications project in Peru during 2019 and political volatility in other areas ofstrategically focus on the region, concluded to pursue an orderlyNorth American market, substantially completing the exit of our Latin American operations. Whilecommunications operations during 2020, which we have incurred costs and expect to incur

PipelineUnderground Utility and Industrial Infrastructure Services Segment.Solutions. For several years we have focused on increasing our pipelineunderground utility and industrial services offeringsinfrastructure solutions related to specialty services and industries that we believe are driven by regulated utility spending, regulation, replacement and rehabilitation of aging infrastructure and safety and environmental initiatives, which we believe provide a greater level of business sustainability and predictability. These service offerings include gas utility services, pipeline integrity services and downstream industrial services. We believe focusing on these services all of which we have expanded through organic growth, geographic expansion initiatives and select acquisitions. This strategy is also intendedhelps to mitigateoffset the seasonality and cyclicality of our larger pipeline project activities, whichbusiness, and although our strategic focus on larger pipeline projects has decreased, we are not strategically investing in but continue to pursue project opportunities to the extent they fitsatisfy our margin and risk profiles and support the needs of our customers.
As discussed in ThoughCOVID-19 Pandemic - Response and Impact, though we have experienced short-term disruptions in 2020 and to a lesser extent to date in 2021 due to the impact of the COVID-19 pandemic, in certain metropolitan markets, in recent yearswe believe demand has increased for our gas utility distribution services will increase as a result of lower natural gas prices, increasing regulatory requirements and customer desire to upgrade and replace aging infrastructure.infrastructure and increasing regulatory requirements. In particular, natural gas utilities have implemented multi-decade modernization programs to replace aging cast iron, and bare steel, gas and plastic system infrastructure with modern materials for safety, reliability and environmental purposes.
We believe there are also growth opportunities for our pipeline integrity, rehabilitation and replacement services, as regulatory measures have increased the frequency orand stringency of pipeline integrity testing requirements. Regulatory requirements continue to encouragethat require our customers to test, inspect, repair, maintain and replace pipeline infrastructure to ensure that it operates safely, reliablyin a safe, reliable and in an environmentally conscious manner. Further, permitting challenges associated with construction of new pipelines can make

existing pipeline infrastructure more valuable, motivating owners to extend the useful life of existing pipeline assets through integrity initiatives. Due to these dynamics, we expect demand

We provide critical path solutionsmidstream and related specialtyindustrial services operations has declined as customers reduced and deferred regularly scheduled maintenance and capital projects due to lack of demand for refined products. Our services to refinery and chemical processing facilities,downstream industrial energy customers, which are primarily located along the Gulf Coast of the United States and in other select markets in North America. WhileAmerica, have been negatively impacted by the COVID-19 pandemic haschallenging overall energy market conditions that resulted in an overall decline in global demand for refined products during 2020 and 2021. While demand for our critical path catalyst services has remained solid, in the second half of 2020 customers began reducing onsite activity for our other services and have deferred maintenance and certain turnaround projects to late 2021 and 2022. Despite the current market conditions, we believe there are significant long-term opportunities for ourthese services, including our high-pressure and critical-path turnaround services, as well as our capabilities with respect to instrumentation and electrical services, piping, fabrication and storage tanks services, and other industrial services. We believeservices, and that processing facilities located along the U.S. Gulf Coast region should have certain long-term strategic advantages due to their proximity to affordable hydrocarbon resources. However, these processing facilities can also be negatively impacted for short-term periods due to severe weather events, such as hurricanes, tropical storms and floods. Additionally, due to the COVID-19 pandemic and challenging overall energy market conditions, we have recently experienced a decrease in demand for certain of these services. While demand for our critical path catalyst solutions has remained solid, in the second quarter of 2020 customers began restricting onsite activity for our other services and have deferred maintenance and certain turnaround projects to 2021 or possibly 2022.
With respect to large pipeline project opportunities, a number of such projects from the North American shale formations and Canadian oil sands to power plants, refineries, liquefied natural gas (LNG) export facilities and other demand centers are in various stages of development. While we believe many of our customers remain committed to these projects given the cost and time required to move from conception to construction, the overall larger pipeline market is cyclical and there is risk the projects will not move forward or be delayed or canceled. For example, in July 2020, the project sponsors of an approximately 600-mile natural gas pipeline under construction in the eastern United States that one of our subsidiaries has been contracted to construct a portion of announced that they are no longer moving forward with the project. Furthermore, our revenues related to larger pipeline projects have declined over the last few years.
Due to its abundant supply and current low price, we also believe natural gas will remain a fuel of choice for both primary power generation and backup power generation for renewable-driven power plants in North America. The favorable characteristics of natural gas also position the United States as a leading competitor in the global LNG export market, which has the potential to continue to grow over the coming years as approved and proposed LNG export facilities are developed. In certain areas, the existing pipeline system infrastructure is insufficient to support these expected future developments, which could provide additional opportunities for our services.
Although portions of our pipeline and industrial infrastructure services are influenced by hydrocarbon production volume rather than shorter-term changes in commodity prices,Furthermore, the broader oil and gas industry is highly cyclical and subject to price and production volume volatility, such as the current low commodity price environment, which can impact demand for our services. For example, certain of our end markets where the price of oil is influential, such as Australia, the Canadian Oil Sands and certain oil-driven U.S. shale formations, have been materially impacted by the current challengingchallenged energy market conditions. We have also entered the late-stage of the current construction cycle of larger pipeline projects, while the anticipated next cycle of larger projects could be impacted by various factors, including, among other things, permitting delays and worksite access limitations related to environmental regulations. As a result of these dynamics, our revenues related to larger pipeline projects have declined significantly over the last few years. This dynamic is supportive of our increased focus on specialty services and industries that are driven by regulated utility spending, regulation, replacement and rehabilitation of aging infrastructure and safety and environmental initiatives, which we believe provide a greater level of business sustainability and predictability.
Lastly, we believe there are also longer-term opportunities that may arise in this segment. For example, we believe natural gas, due to its expected abundant supply and attractive price over the long-term, will remain a fuel of choice for both primary power generation and backup power generation for renewable power plants in North America, which we believe could position North America as a leading competitor in the global LNG export market. In certain areas, the existing pipeline system infrastructure is insufficient to support any future LNG export facilities, which could provide additional opportunities for our business. We also believe that customers in this segment may implement strategies to reduce carbon emissions produced from their operations, which could provide incremental opportunities for our services, including developing infrastructure for blending hydrogen into natural gas flow to customers, further investment in renewable energy generation opportunities and carbon capture projects that could include building or repurposing pipeline infrastructure. While certain customers are in various stages of evaluating these types of strategies, we expect that any meaningful opportunities would only arise in the longer term.
COVID-19 Pandemic and Related Economic Impact. The effects of the COVID-19 pandemic continue to significantly impact global economies due to, among other things, workforce and travel restrictions and supply chain, production and other logistical disruptions. While we have continued to operate substantially all of our activities as a provider of essential services, during the course of the pandemic our operations and financial results have been adversely impacted by reduced customer spending and demand for certain of our services (including as described above), as well as governmental responses to the COVID-19 pandemic, including shut-down orders and limitations on work site practices implemented by governments, which have negatively impacted (i) our Canadian operations and financial results during 2020 and to date in 2021; (ii) our Australian operations and financial results during 2020 and to date in 2021; (iii) our operations in certain major U.S. metropolitan markets that were meaningfully impacted by the pandemic during the first and second quarters of 2020; and (iv) our Latin American operations during 2020.
Additionally, vaccination and testing requirements related to COVID-19 could impact our business in the future. In September 2021, the Occupational Safety and Health Administration was directed to implement an emergency temporary standard requiring employers with 100 or more employees to ensure their workforce is fully vaccinated or to require unvaccinated workers to produce a negative COVID-19 test result on at least a weekly basis. This standard has been issued and is expected to be published on November 5, 2021 and fully applicable by January 2022. The standard will apply to us and the costs related to mandatory testing could represent a substantial expense to us. Additionally, in September 2021, President Biden issued an executive order that requires federal contractors and subcontractors to mandate their employees be fully vaccinated against COVID-19 by January 2022. Some of our operating companies, as well as many of our customers, are considered federal contractors, or are performing work under contracts covered by the executive order. As such, employees of those
5446


operating companies may need to be fully vaccinated to perform related work. In addition, many of our customers have established, or we believe are in the process of establishing, vaccination requirements that would apply to our employees performing work on their premises, or in proximity of their employees. The implementation of these vaccination and testing requirements could have a material adverse effect on our business, financial condition, results of operations or cash flows in the event that, among other things, a significant portion of our workforce does not choose to become vaccinated, the costs related to mandatory testing for unvaccinated employees are significant, the time away from work for testing is disruptive to our operations, or our unvaccinated employees are unable to perform work for customers that require vaccination.
We also continue to monitor supply chain and other logistical challenges with respect to certain materials and equipment necessary for the performance of our business, including, among other things, availability and costs related to steel, materials for renewable energy projects, new vehicles for our fleet (both on-road and specialty vehicles) and vehicle parts (e.g., tires). For example, we believe some participants in the renewable energy market are experiencing supply chain challenges, resulting in delays and shortages of materials necessary for the construction of renewable projects in the near term. While we believe many of our renewable energy customers are generally better equipped to manage near-term supply chain disruptions than smaller competitors, these challenges could impact our ability to perform renewable services during this period. Additionally, based on, among other things, the significant worldwide shortage of semiconductors, vehicle manufacturers are experiencing production delays with respect to vehicles we utilize in our operations. While we believe we have taken steps to secure delivery of such vehicles in the near term and do not anticipate any significant disruptions with respect to our fleet, to the extent the production issues become worse than expected or become longer-term in nature, our operations could be negatively impacted.
The broader and longer-term implications of the COVID-19 pandemic on our results of operations and overall financial performance and position remain highly uncertain and variable, and we expect continued operational challenges in the remainder of 2021 and into 2022 for portions of our operations. The future impact that the pandemic, or any resulting market disruption and volatility, will have on our business, cash flows, liquidity, financial condition and results of operations will depend on future developments, including, among others, the duration and severity of the pandemic; the actions taken by governmental authorities, customers, suppliers and other third parties in response to the pandemic and the consequences of those actions; our workforce availability; and the timing and extent to which normal economic and operating conditions resume and continue.
Regulatory Challenges and Opportunities. The regulatory environment creates both challenges and opportunities for our business, and in recent years electric power infrastructure solutions and pipelineunderground utility and infrastructure servicessolutions margins have been impacted by regulatory and permitting delays in certain periods, particularly with respect to larger electric transmission and larger pipeline projects. Regulatory and environmental permitting processes continue to create uncertainty for projects and negatively impact customer spending, and delays have increased as the COVID-19 pandemic has impacted regulatory agency operations. As anFor example, a recent changes to the federal district court ruling vacating the U.S. Army Corps of Engineers Clean Water Act Section 404 Nationwide Permit 12 may resultand related executive orders have impacted certain projects and resulted in increased costs and project interruptions orand delays if we or ouras customers are increasingly forced to seek additional or revised individual permits from the U.S. Army Corps of Engineers.
However, we believe that there are also several existing, pending or proposed legislative or regulatory actions that may alleviate certain regulatory and permitting issues and positively impact long-term demand, particularly in connection with electric power infrastructure and renewable energy spending. For example, regulatory changes affecting siting and right-of-way processes could potentially accelerate construction for transmission projects, and state and federal reliability standards are creating incentives for system investment and maintenance. We alsoAdditionally, as described above, we consider renewable energy, including solar and wind generation facilities, to be an ongoing opportunity for our engineering,opportunity; however, policy and economic incentives designed to support and encourage such projects can create variability of project management and installation services; however, the economic feasibility of some of these projects remains subject to the continued availability of tax incentive programs.timing.
Labor Resource Availability and Cost. In addition to the health and safety measures we are taking to ensure labor resource availability during the COVID-19 pandemic, weWe continue to address the longer-term need for additional labor resources in our markets. Ourmarkets, as our customers continue to seek additional specialized labor resources to address an aging utility workforce and longer-term labor availability issues, increasing pressure to reduce costs and improve reliability, and increasing duration and complexity of their capital programs. We believe these trends will continue, possibly to the point wheresuch a degree that demand for labor resources will outpace supply. Furthermore, the cyclical nature ofincreased demand for our services based on the natural gas and oil industrydynamics described above can create shortages of qualified labor in those markets during periods of high demand.our markets. Our ability to capitalize on available opportunities is limited by our ability to employ, train and retain the necessary skilled personnel, and therefore we are taking proactive steps to develop our workforce, including through strategic relationships with universities, the military and unions and the expansion and development of our training facility and postsecondary educational institution. Although we believe these initiatives will help address workforce needs, meeting our customers’ demand for labor resources could remain challenging.
Additionally, we continue to monitor our labor markets and expect labor costs to increase based on increased demand for our services and, to a lesser extent, the recent escalated inflationary environment in the United States. Our labor costs are passed through in certain of our contracts, and the portion of our workforce that is represented by labor unions typically operate under
47

multi-year collective bargaining agreements, which provide some visibility into future labor costs. While we do not currently believe this environment will present a material risk to our profitability and would expect to be able to adjust contract pricing with certain customers to the extent wages and other labor costs increase, whether due to renegotiation of collective bargaining agreements or market conditions, meaningful increases in our labor costs could have a material adverse effect on our business, financial condition, results of operations or cash flows to the extent we cannot do so.
Acquisitions and Investments. We believe potential acquisition and investment opportunities exist in our industries and adjacent industries, primarily due to the highly fragmented and evolving nature of those industries and inability of many companies to expand and modernize due to capital or liquidity constraints. We continue to evaluate opportunities that are expected to, among other things, broaden our customer base, expand our geographic area of operations and grow and diversify our portfolio of services.
Significant Factors Impacting Results
Our revenues, margins and other results of operations can be influenced by a variety of factors in any given period, including those described in Cautionary Statement About Forward-Looking Statements and Information below,above, Item 1A. Risk Factorsof Part II of this Quarterly Report and Item 1A. Risk Factorsof Part I of our 20192020 Annual Report, and those factors have caused fluctuations in our results in the past and are expected to cause fluctuations in our results in the future. Additional information with respect to certain of those factors is provided below.
Seasonality. Typically, our revenues are lowest in the first quarter of the year because cold, snowy or wet conditions can create challenging working environments that are more costly for our customers or cause delays on projects. In addition, infrastructure projects often do not begin in a meaningful way until our customers finalize their capital budgets, which typically occurs during the first quarter. Second quarter revenues are typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather can often impact productivity. Third quarter revenues are typically the highest of the year, as a greater number of projects are underway and operating conditions, including weather, are normally more accommodating. Generally, revenues during the fourth quarter are lower than the third quarter but higher than the second quarter, as many projects are completed and customers often seek to spend their capital budgets before year end. However, the holiday season and inclement weather can sometimes cause delays during the fourth quarter, reducing revenues and increasing costs. These seasonal impacts are typical for our U.S. operations, but seasonality for our international operations may differ. For example, revenues in Canada are typically higher in the first quarter because projects are often accelerated in order to complete work while the ground is frozen and prior to the break up, or seasonal thaw, as productivity is adversely affected by wet ground conditions during warmer months. Additionally, as referenced above in COVID-19 Pandemic – Response and Impact, portions of our operations experienced significant challenges during the second quarter of 2020 as a result of the COVID-19 pandemic which impactedaffected typical seasonality during 2020, and we believe thatour typical seasonality could also be impacted during the ongoingremainder of 2021 due to continued uncertainty regarding the future impact of the pandemic could impact our typical seasonality in 2021.pandemic.

Weather, natural disasters and emergencies. The results of our business in a given period can be impacted by adverse weather conditions, severe weather events, natural disasters or other emergencies, which include, among other things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms, tornadoes, floods, blizzards, extreme temperatures, wildfires, post-wildfire floods and debris flows, pandemics (including the ongoing COVID-19 pandemic) and earthquakes. These conditions and events can negatively impact our financial results due to, among other things, the termination, deferral or delay of projects, reduced productivity and exposure to significant liabilities. See COVID-19 PandemicOverviewResponse and ImpactBusiness Environment above for further discussion regarding the current and expected impact of the COVID-19 pandemic. However, in some cases, severe weather events can increase our emergency restoration services, which typically yield higher margins due in part to higher equipment utilization and absorption of fixed costs.
Cyclicality and demandDemand for services. OurWe perform the majority of our services under existing contracts, including master service agreements (MSAs) and similar agreements pursuant to which our customers are not committed to specific volumes of our services. Therefore our volume of business maycan be adverselypositively or negatively affected by declinesfluctuations in demand forthe amount of work our services or delayscustomers assign us in new and ongoing projects due to cyclicality,a given period, which may vary by geographic region. Project schedules also fluctuate, particularly in connection with larger, more complexFor example, to the extent our customers accelerate grid modernization or longer-term projects, which can affect the amounthardening programs or face deadlines to meet regulatory requirements for rehabilitation, reliability or efficiency, our volume of work performedcould increase under existing agreements. Also, as described above in Overview –Business Environment, we have experienced reductions in demand for certain services as a given period. For example,result of the timing of obtaining permits and other approvals on a larger project may be delayed, and we may need to maintain a portion of our workforce and equipment in an underutilized capacity to ensure we are strategically positioned to deliver onCOVID-19 pandemic, as well as the project when it moves forward.currently challenged energy market. Examples of other items that may cause demand for our services to fluctuate materially from quarter to quarter include: the financial condition of our customers, their capital spending and their access to capital; economic and political conditions on a regional, national or global scale, including interest rates, governmental regulations affecting the sourcing of certain materials and equipment, and other changes in U.S. and global trade relationships; our customers’ capital spending, including on larger pipeline and electrical infrastructure projects; commodity and material prices; and project deferrals and cancellations. As described above in COVID 19 Pandemic – Response and Impact, we have experienced reductions in demand for certain of our services as a result of disruptions due to shelter-in-place and worksite access restrictions and delays in regulatory agency operations due to the COVID-19 pandemic, as well as the decline in commodity prices and decreased commodity production levels.
Revenue mix.mix and impact on margins. The mix of revenues based on the types of services we provide in a given period will impact margins, as certain industries and services provide higher-margin opportunities. For example, installation work is often performed on a fixed price basis, while maintenance work is often performed under pre-established or negotiated prices or cost-plus pricing arrangements. Margins for installation work varies by project but can be higher than maintenance work due to higher risk. We have historically derived approximately 30% to 35% of our annual revenues from maintenance work, but a higher portion of maintenance work in any given period may affect our gross margins for that period. Additionally, the areas in which we operate during a given period can impact margins. Some areas offer the opportunity for higher margins due to their more difficult geographic characteristics, such as urban settings or mountainous and other difficult terrain. However, margins may also be negatively impacted by unexpected difficulties that can arise due to those same characteristics, as well as unexpected site conditions.
Size, scope and complexity of projects. LargerOur larger or more complex
48

projects typically include, among others, electric transmission projects with higher voltage capacities; pipeline projects with larger-diameter throughput capacities; large-scale renewable generation projects, which we expect to increase subsequent to our acquisition of Blattner; and projects with increased engineering, design or construction complexities;complexities, more difficult terrain requirements;or geographical requirements, or longer distance requirementsrequirements. These projects typically yield opportunities for higher margins than our recurring services under MSAs described above, as we assume a greater degree of performance risk and there is greater utilization of our resources for longer construction timeframes. However, larger projects are subject to additional risk of regulatory delay and cyclicality. For example, our revenues with respect to larger electric transmission and pipeline projects have declined significantly in recent years, and a significant number of larger projects have been delayed or cancelled during that same period. Project schedules also fluctuate, particularly in connection with larger, more complex or longer-term projects, which can affect the amount of work performed in a given period. Furthermore, smaller or less complex projects typically have a greater number of companies competing for them, and competitors at times may more aggressively pursue available work. A greater percentage of smaller scale or less complex work also could negatively impact margins due to the inefficiency of transitioning between a largergreater number of smaller projects versus continuous production on fewer larger projects. Also,As a result, at times we may choose to maintain a portion of our workforce and equipment in an underutilized capacity to ensure we are strategically positioned to deliver on larger projects when they move forward.
Project variability and performance. Margins for a single project may fluctuate period to period due to changes in the volume or type of work performed, the pricing structure under the project contract or job productivity. Additionally, our productivity and performance on a project can vary period to period based on a number of factors, including unexpected project difficulties or site conditions;conditions (including in connection with difficult geographic characteristics); project location, including locations with challenging operating conditions; whether the work is on an open or encumbered right of way; inclement weather or severe weather events; environmental restrictions or regulatory delays; protests, other political activity or legal challenges related to a project; and the performance of third parties. Moreover, we currently generate a significant portion of our revenues under fixed price contracts, and fixed price contracts are more common in connection with our larger and more complex projects that typically involve greater performance risk. Furthermore, subsequent to our acquisition of Blattner, we expect the portion of our revenues generated under fixed price contracts to increase significantly. Under these contracts, we assume risks related to project estimates and execution, and project revenues can vary, sometimes substantially, from our original projections due to a variety of factors, including the additional complexity, timing uncertainty or extended bidding, regulatory and permitting processes associated with these projects. These variations can result in a reduction in expected profit or the incurrence of losses on a project or the issuance of change orders or assertion of contract claims against customers. See Revenue Recognition - Contract Estimates in Note 2 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report for further information regarding changes in estimated contract revenues and/or project costs, including any significant project gains or losses in connection with fixed price contracts that have impacted our results, and determinations with respect to the recognition of change orders and claims as contract price adjustments.
Subcontract work and provision of materials. Work that is subcontracted to other service providers generally yields lower margins, and therefore an increase in subcontract work in a given period can decrease margins. In recent years, we have subcontracted approximately 15% to 20% of our work to other service providers. Our customers are usually responsible for supplying the materials for their projects; however,projects. However, under some contracts, including contracts for projects where we provide engineering, procurement and construction (EPC) services, we agree to procure all or part of the required materials. Margins may be lower on projects where we furnish a significant amount of materials, including projects where we provide engineering, procurement and construction (EPC) services, as our markup on materials is generally lower than our markup on labor costs. Furthermore, fluctuationscosts, and in the price or availability of materials we or our customers procure, including as a result of changes in U.S. or global trade relationships, governmental regulations affecting the sourcing of certain materials
56


and equipment or other economic or political conditions, may impact our margins or cause delays. In a given period an increase in the percentage of work with highergreater materials procurement requirements may decrease our overall margins. Furthermore, fluctuations in the price or availability of materials and equipment we or our customers procure may impact our margins or cause delays on projects, including as a result of inflation; supply chain and other logistical challenges resulting from the COVID-19 pandemic or otherwise; governmental regulations affecting the sourcing of materials and equipment and other changes in U.S. or global trade relationships; or other economic or political conditions.
Foreign currency risk. Our financial performance is reported on a U.S. dollar-denominated basis but is partially subject to fluctuations in foreign currency exchange rates. Fluctuations in exchange rates relative to the U.S. dollar, primarily Canadian dollars and Australian dollars, can materially impact margins and comparisons of our results of operations and impact comparability between periods.

Selling, general and administrative expenses. The increase was primarily attributable to a $13.1 million increase in compensation expense primarily due to increased non-cash stock-based compensation expense and a $4.9 million increase in expenses associated with acquired businesses. Also contributing to the increase in selling, general and administrative expense was a $3.3 million increase in the fair market value of deferred compensation liabilities during the three months ended
57


September 30, 2020, as compared to a $0.4 million increase in the fair market value of deferred compensation liabilities during the three months ended September 30, 2019. The fair market value changes in deferred compensation liabilities were partially offset by changes in the fair value of assets associated with the deferred compensation plan, which are included in other income (expense), net. Partially offsetting these increases were decreases in certain expenses related to our cost containment measures in the current operating environment, including a $7.9 million decrease in travel and related expenses. Also partially offsetting the increases was a $4.3 million decrease in legal and other contracted services. Selling, general and administrative expenses as a percentage of revenues increaseddecreased to 8.2% for the three months ended September 30, 2021, as compared to 8.3% for the three months ended September 30, 2020 from 7.3% for the three months ended September 30, 2019,2020. The increase in selling, general and administrative expenses was partially attributable to a $15.2 million increase in compensation expense, which was primarily due to increased personnel to support business growth and increased incentive compensation expense as a result of higher levels of operating performance, and a $5.0 million increase in travel and related expenses, which were below historical levels in 2020 as a result of the COVID-19 pandemic. These increased expenses were partially offset by a $3.3 million decrease in revenues described above.expense related to deferred compensation liabilities. The changes in fair market value of deferred compensation liabilities were offset by corresponding changes in the fair market value of assets associated with the deferred compensation plan, and these corresponding changes are included in other income (expense), net.
Amortization of intangible assets. The increase was primarily due to increased amortization of intangible assets associated with recently acquired businesses, partially offset by reduced amortization expense associated with previouslyfrom older acquired intangible assets, as certain of those assets became fully amortized.

Change in fair value of contingent consideration liabilities. Contingent consideration liabilities are payable in the event certain performance objectives are achieved by an acquired business during designated post-acquisition periods. The overall change in fair value associated with these liabilities was primarily due to changes in performance in post-acquisition measurement periods by certain acquired businesses and the effect of present value accretion on fair value calculations. Further changes in fair value are expected to be recorded periodically until the contingent consideration liabilities are settled, with a significant portion of such obligations expected to be settled in late 2020 or early 2021.

Other comprehensive income (loss). Other comprehensive income (loss) results from translation of the balance sheets of our foreign operating units, which are primarily located in Canada and Australia and have functional currencies other than the U.S. dollar, and therefore are affected by the strengthening or weakening of the U.S. dollar against such currencies. The loss in the three months ended September 30, 2021 was primarily impacted by the strengthening of the U.S. dollar against the Canadian and Australian dollars as of September 30, 2021 when compared to June 30, 2021. The gain in the three months ended September 30, 2020 was primarily impacted by the weakening of the U.S. dollar against both the Canadian and Australian dollars as of September 30, 2020 when compared to June 30, 2020. The loss in the three months ended September 30, 2019 was primarily impacted by the strengthening of the U.S. dollar against both the Canadian and Australian dollars as of September 30, 2019 when compared to June 30, 2019.

Selling, general and administrative expenses. ThisSelling, general and administrative expenses as a percentage of revenues increased to 8.7% for the nine months ended September 30, 2021 from 8.6% for the nine months ended September 30, 2020. The increase in selling, general and administrative expenses was primarily dueattributable to a $24.6$26.7 million increase in compensation expenses,expense, largely associated with increased incentive and non-cash stock-basedstock compensation expense as a result of higher levels of operating performance and an $18.1increase in salaries and benefits due to increased personnel to support business growth; a $21.9 million increase in expenses associated with acquired businesses.

Amortization of intangible assets. The increase was primarily due to increased amortization of intangible assets associated with recently acquired businesses, partially offset by reduced amortization expense associated with previouslyolder acquired intangible assets, as certain of these assets became fully amortized.
Asset impairment charges. During the nine months ended September 30, 2021, we recognized a $2.3 million asset impairment charge related to certain equipment that was not utilized in our core operations and was subsequently sold in October 2021.
Change in fair value of contingent consideration liabilities. Contingent consideration liabilities are payable in the event certain performance objectives are achieved by an acquired business during designated post-acquisition periods. The overall change in fair value associated with these liabilities was primarily due to changes in performance in post-acquisition measurement periods by certain acquired businesses and the effect of present value accretion on fair value calculations. Further changes in fair value are expected to be recorded periodically until the contingent consideration liabilities are settled, with a significant portion of such obligations expected to be settled in late 2020 or early 2021. See Contractual Obligations - Contingent Consideration Liabilities for more information.settled.
Interest expense. Interest expense decreasedincreased primarily due to higher levels of outstanding debt and a lowerhigher weighted average interest rate partially offset byduring the nine months ended September 30, 2021 compared to 2020.
Interest income. Interest income increased borrowing.primarily due to interest received related to a settlement with a customer.
Other income (expense), net. The net other income for the nine months ended September 30, 2021 included $6.5 million related to foreign currency exchange gains, as compared to $4.9 million of foreign currency exchange gains for the nine months ended September 30, 2020. Also favorably impacting other income was $5.3 million of income associated with our deferred compensation plan, as compared to $1.9 million of income in 2020. This income related to the deferred compensation plan was largely offset by corresponding changes in the fair market value of the liabilities associated with our deferred compensation plan, which are recorded in selling, general, and administrative expenses, as discussed above. Also favorably impacting the nine months ended September 30, 2021 were a $2.5 million benefit payment from a company-owned life insurance policy held in connection with our deferred compensation plan and $1.9 million of equity in earnings of non-integral unconsolidated affiliates. The net other expense for the nine months ended September 30, 2020 was primarily related toalso included a $9.3 million impairment associated with an investment in a water and gas pipeline infrastructure contractor located in Australia that is accounted for using the cost method of accounting and $8.7 million of impairments associated with two non-integral equity investments that have beenwere negatively impacted by the decline in demand for refined petroleum products, which were partially offset by an $8.9 million legal settlement received and the favorable impact of $4.9 million related to foreign currency transactions. The net other income for the nine months ended September 30, 2019 was primarily due to the deferral and subsequent recognition of earnings on a large electric transmission project in Canada that was substantially completed and placed into commercial operation during the three months ended March 31, 2019. As a result of the project completion, we recognized $60.3 million of earnings that were deferred in prior periods.received.
Provision for income taxes. The effective tax rates for the nine months ended September 30, 2021 and 2020 were 23.2% and September 30, 2019 were 29.9% and 32.8%. The higher effective taxlower rate for the nine months ended September 30, 20192021 was primarily due to the $79.2recognition of an $19.7 million chargetax benefit that resulted from equity incentive awards vesting at a higher fair market value than their grant date fair market value, as compared to the recognition of $2.6 million associated with the terminated telecommunications project in Peru, for which no incomethis tax benefit for the nine months ended September 30, 2020, which was recognized.due to a smaller difference between the vest date fair market value and grant date fair market value of vested equity incentive awards.
Other comprehensive income (loss). Other comprehensive income (loss) results from translation of the balance sheets of our foreign operating units, which are primarily located in Canada and Australia and have functional currencies other than the U.S. dollar, and therefore are affected by the strengthening or weakening of the U.S. dollar against such currencies. The loss in the nine months ended September 30, 20202021 was impacted primarily by the strengthening of the U.S. dollar against the Australian dollar as of September 30, 2021 when compared to December 31, 2020. The loss in the nine months ended September 30, 2020 was impacted by the strengthening of the U.S. dollar against both the Canadian dollarand Australian dollars as of September 30, 2020 when compared to December 31, 2019.

Segment Results
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. Classification of our operating unit revenues by type of work for segment reporting purposes can at times require judgment on the part of management. Our operating units may perform joint projects for customers in multiple industries, deliver multiple types of services under a single customer contract or provide service offerings to various industries. For example, we perform joint trenching projects to install distribution lines for electric power and natural gas customers. Our integrated operations and common administrative support for operating units require that certain allocations be made to determine segment profitability, including allocations of shared and indirect costs (e.g., facility costs), indirect operating expenses (e.g., depreciation), and general and administrative costs. Certain corporate costs are not allocated, including payroll and benefits, employee travel expenses, facility costs, professional fees, acquisition costs, non-cash

Electric Power Infrastructure ServicesSolutions Segment Results
The increase in revenues for the three months ended September 30, 20202021 was primarily due to continued favorable dynamics across our core utility market and increased contributions from larger transmission projects in Canada, continued growth indemand for our North American communications operations andelectric power services, as well as a $65$55 million increase in revenues attributable to acquired businesses. Additionally, revenues for the three months ended September 30, 2020 included a $1272021 were positively impacted by $27 million increase in incremental emergency restoration services revenues whichand $15 million related to more favorable foreign currency exchange rates, primarily the Canadian dollar and U.S. dollar exchange rate.
The increase in operating income was largely offset by aprimarily attributable to increased revenues. The decrease in base distribution services as crews were reallocatedoperating margin was primarily attributable to emergency restoration services, as well as decreased revenues associated with grid modernizationnormal project variability and fire hardening programs in the western United States as compared tohigher general and administrative expenses during the three months ended September 30, 2019.2021 as compared to lower than normal levels of general and administrative expenses for the three months ended September 30, 2020. Favorably impacting operating income and operating margin during the three months ended September 30, 2021 was the incremental impact of our equity interest in LUMA.
As a result of a contract termination associated with a large telecommunications projectIn addition, in Peru, which is discussed further below, and other considerations including the long-term political stability of the region,early 2020, we decided to pursue an orderly exit of our operations in Latin America. OurAmerica and substantially completed such exit as of December 31, 2020. For the three months ended September 30, 2020, Electric Power Infrastructure Solutions operating income included $15.4 million of operating losses related to Latin American operations, which negatively impacted operating results are separately provided above,margin by 80 basis points.
Underground Utility and we believe providing visibility into these results is beneficialInfrastructure Solutions Segment Results
The increase in revenues for the three months ended September 30, 2021 was primarily due to understanding the performance of our ongoing operations. These operations have been adverselyincreased demand for gas distribution and industrial services. Revenues were also favorably impacted by a $10 million increase in revenues attributable to acquired businesses and $6 million related to more favorable foreign currency exchange rates, primarily the Canadian dollar and U.S. dollar exchange rate. The increase in revenues attributable to these items was partially offset by disruptions along the U.S. Gulf Coast attributable to Hurricane Ida and broader challenges in the energy market that negatively impacted our industrial services operations, as well as governmental restrictions and protocols associated with the COVID-19 pandemic that negatively impacted our operations in non-U.S. markets.
The decrease in operating income and operating margin was primarily due to shelter-in-place restrictions and other work disruptions, and as a result we have accelerated various contract terminations and other activities in order to expedite cessation of operations in the region. As a result of these factors,more favorable adjustments on certain large pipeline projects during the three months ended September 30, 2020, our Latin American operations generated an operating loss of $15.4 million as compared to an operating loss of $2.2 million during the three months ended September 30, 2019. As of September 30, 2020, more than 80% of the projects in Latin America thatwhich were active at the beginning of 2020 have been completed, and the remaining projects are not expected to be material individually or in the aggregate. For the full year of 2020, our Latin American operations are expected to generate revenues of $10 million to $15 million and an operating loss of $55 million to $60 million.
Operating income and operating income as a percentage of revenues were positively impacted by improved performance across the segment, including increased revenues for larger transmission projects in Canada and emergency restoration services revenues, both of which contributed to improved equipment utilization and fixed cost absorption. Additionally, operating income for the three months ended September 30, 2019 was negatively impacted by severe weather and other delays on certain larger transmission projects in Canada that resulted in elevated levels of unabsorbed costs. The positive factors were partially
61


offset by a reduction in fire hardening services in the western United States during the three months ended September 30, 2020 as compared to the three months ended September 30, 2019. The equity in earnings of integral unconsolidated affiliates primarily relates to the commencement of transition services under the agreement awarded to LUMA in June 2020 for the operation and maintenance of the electric transmission and distribution system in Puerto Rico.
Pipeline and Industrial Infrastructure Services Segment Results
The decrease in revenues was primarily due to disruptions resulting from shelter-in-place and worksite access restrictions related to the COVID-19 pandemic and the compounding impact on the challenged energy market, including decreased capital spending by our customers on industrial services due to the significant decline in demand for refined petroleum products. Revenues associated with larger pipeline projects also decreased as compared to the three months ended September 30, 2019, as the timing of such projects is highly variable due to potential permitting delays, worksite access limitations related to environmental regulations and seasonal weather patterns. The decrease was partially offset by approximately $70 million in incremental revenues from acquired businesses. Our original expectations for 2020 included $500 million of revenues from larger pipeline projects, which we expect to be a normalized level of annual revenues for such projects in the near term. However, due to the aforementioned challenges, as well as the deferral of certain project opportunities into 2021, we expect contributions from larger pipelines projects to be significantly below such level in 2020.
The decreases in operating income and operating income as a percentage of revenues were primarily due to the decrease in revenues discussed above, including a decrease in revenues associated with industrial services that negatively impacted our ability to cover fixed and overhead costs and adverse weather conditions across our Canadian pipeline operations. However, the three months ended September 30, 2020 benefited from favorable adjustments on certain larger pipeline projects associated with the recognition of previously

deferred milestone payments and reduced contingencies due to a reduction in the scope of work to be completed on a project that is now complete, as well as the completion of certain other projects earlier than anticipated. We also expect thatAdditionally, as referenced above, operating income for both the project for which the scope of work was reduced will be terminatedthree months ended September 30, 2021 and 2020 were adversely impacted by the end of 2020COVID-19 pandemic and are workingthe overall challenged energy market, with the customergreater negative impact occurring in the three months ended September 30, 2020 due to determine how the project will close out.

Corporate and Non-allocatedNon-Allocated Costs
The increase in corporate and non-allocated costs during the three months ended September 30, 2021 was primarily due to a $12.9$6.7 million increase in non-cash stock-based and incentive compensation expense andas a $4.4result of higher levels of operating performance relative to incentive compensation targets, a $3.1 million increase in intangible asset amortization.amortization, a $1.9 million increase in salaries and benefits due to increased personnel to support business growth and a $1.6 million increase in travel and related expenses, which were below historical levels in 2020 as a result of the COVID-19 pandemic. Partially offsetting these increases were a $6.4$4.2 million decrease in acquisition and integration costs and decreasesa $3.3 million decrease in certain expenses resulting from cost containment effortsexpense related to deferred compensation liabilities. The changes in fair market value of deferred compensation liabilities were offset by corresponding changes in the current operating environment.fair market value of assets associated with the deferred compensation plan, which are recorded in other income (expense), net.

Electric Power Infrastructure ServicesSolutions Segment Results
The increase in revenues for the nine months ended September 30, 2021 was primarily due to continued favorable dynamics across our core utility market and increased demand for our electric power services, as well as a $106$195 million increase in revenues attributable to acquired businesses. Additionally, revenues for the nine months ended September 30, 2021 were positively impacted by $80 million related to more favorable foreign currency exchange rates, primarily the Canadian dollar and U.S. dollar exchange rate, and a $53 million increase in emergency restoration services revenues, higher revenues on larger transmission projects in Canada, a $118 millionrevenues.
The increase in revenues in our North American communication operations. and approximately $100 million of incremental revenues attributable to acquired businesses. Also contributing to the increase was increased customer spending on distribution services. These increases were partially offset by lower revenues associated with grid modernization and fire hardening programs in the western United States as compared to the prior comparable period.
As discussed above, we have decided to pursue an orderly exit of our Latin American operations, which have been adversely impacted by the COVID-19 pandemic due to shelter-in-place restrictions and other work disruptions that have resulted in our acceleration of various contract terminations and other activities in order to expedite cessation of operations in the region. As a result of these factors, during the nine months ended September 30, 2020 our Latin American operations generated an operating loss of $46.9 million. During the nine months ended September 30, 2019, the operating loss for our Latin American operations included the recognition of a $79.2 million charge associated with a terminated telecommunications project in Peru, which included a $48.8 million reversal of revenues and a $30.4 million increase in cost of services. The charge included a reduction of previously recognized earnings on the project, a reserve against a portion of the project costs incurred through the project termination date, a reserve against a portion of alleged liquidated damages and recognition of estimated costs to complete the project turnover and close out the project. See Legal Proceedings in Note 11 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report for additional information regarding this project.
Operating income and operating income as a percentage of revenues were positively impacted duringmargin was primarily attributable to improved performance across the nine months ended September 30, 2020 bysegment, including increased revenues from largerlarge transmission projects in Canada and emergency restoration services revenues, both of which contributed to improved equipment utilization and fixed cost absorption. The nine months ended September 30, 2019 was negatively impacted by severe weather and other delays on certain larger transmission projects in Canada that resulted in elevated levels of unabsorbed costs. Partially offsetting these increases between periods was a reduction in fire hardening services in the western United States during the nine months ended September 30, 2020. The equity in earnings of integral unconsolidated affiliates primarily relates to the commencement of transition services under the operation and maintenance agreement awarded to LUMA in June 2020.

Pipeline and Industrial Infrastructure Services Segment Results
The decrease in revenues was primarily due to a decrease in services related to larger pipeline transmission projects, which accounted for as much as a $650 million decrease in revenues, as well as a decrease in industrial services that resulted from decreased capital spending by our customers primarily attributable to the challenging overall energy market conditions, disruptions due to shelter-in-place and worksite access restrictions related to the COVID-19 pandemic. The timing of construction for larger pipeline projects is highly variable due to potential permitting delays, worksite access limitations related to environmental regulations and seasonal weather patterns. These decreases were partially offset by approximately $225 million in revenues from acquired businesses.
The decreases inAlso favorably impacting operating income and operating income as a percentage of revenues during the nine months ended September 30, 2021 was the incremental impact of our equity interest in LUMA. Partially offsetting the positive impact of these items were losses resulting from poor subcontractor performance, challenging site conditions and weather and seasonal impacts on certain communications projects during the first quarter of 2021.
In addition, in early 2020, we decided to pursue an exit of our operations in Latin America and substantially completed such exit as of December 31, 2020. For the nine months ended September 30, 2020, Electric Power Infrastructure Solutions
55

operating income included $46.9 million of operating losses related to Latin American operations, which negatively impacted operating margin by 80 basis points.
Underground Utility and Infrastructure Solutions Segment Results
The decrease in revenues for the nine months ended September 30, 2021 was partially due to reduced revenues associated with large pipeline projects, as the industry has entered the late-stage of the current construction cycle for these projects and the anticipated next cycle of projects has been delayed due to various factors, including, among other things, permitting delays and worksite access limitations related to environmental regulations. Revenues also declined due to lower demand for our services in end markets where the price of oil is influential, as well as reduced capital spending and deferred regularly scheduled maintenance by our midstream and industrial customers as a result of the COVID-19 pandemic. These decreases were partially offset by increased demand for gas distribution services; approximately $20 million in revenues from acquired businesses; and $19 million related to more favorable foreign currency exchange rates, primarily the Canadian dollar and U.S. dollar exchange rate.
The decreases in operating income and operating margin were primarily due to the reductionrecognition of revenues, including revenuesa $23.6 million provision for credit loss related to larger pipeline transmission projects,a receivable from a customer that declared bankruptcy in July 2021 and its affiliate, which generally yield higher margins. Also contributingis described further in Current and Long-Term Accounts Receivable and Allowance for Credit Losses within Note 2 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this decrease were adverse impactsQuarterly Report, and, to a lesser extent, a $2.3 million asset impairment charge related to the planned sale of certain equipment not utilized in our core operations and that was subsequently sold in October 2021. Additionally, operating income for both the nine months ended September 30, 2021 and 2020 were adversely impacted by the COVID-19 pandemic including lower revenues associated with industrial services,and the overall challenged energy market, which negatively impacted our margins and the ability to cover fixed and overhead costs. Additionally, segment results were adversely impacted by the overall challenged energy market, as discussed further above in COVID-19 – Response and Impact. The nine months ended September 30, 2019 included a $23.3 million loss associated with continued rework and start-up delays on a processing facility project in Texas, which was completed at September 30, 2020.
Corporate and Non-allocatedNon-Allocated Costs
The increase in corporate and non-allocated costs was primarily due to a $22.2 million increase in non-cash stock-based and incentive compensation and a $14.8 million increase in intangible asset amortization. Partially offsetting these increases were a $7.6 million decrease in acquisition and integration costs, a $4.0 million decrease in expense associated with the change in fair value of deferred compensation liabilities and decreases in certain expenses related to our cost containment measures in the current operating environment, including a $4.0 million decrease in travel and related expenses. Also offsetting the cost increases was a $0.6 million increase in the fair value of contingent consideration liabilities in the nine months ended September 30, 2020, as compared to an $8.1 million increase in the fair value of contingent consideration liabilities recognized during the nine months ended September 30, 2019.2021 was primarily due to a $10.0 million increase in intangible asset amortization, a $9.2 million increase in incentive and non-cash stock compensation as a result of higher levels of operating performance relative to incentive compensation targets and a $4.5 million increase in expense related to deferred compensation liabilities. The changes in fair market value of deferred compensation liabilities were offset by corresponding changes in the fair market value of assets associated with the deferred compensation plan, which are recorded in other income (expense), net. Also contributing to the increase was a $3.4 million increase in salaries and benefits expense due to increased personnel to support business growth. These increases were partially offset by a $5.2 million decrease in professional fees and a $3.4 million decrease in acquisition and integration costs.
Non-GAAP Financial Measures
EBITDA and Adjusted EBITDA
EBITDA and adjusted EBITDA, financial measures not recognized under GAAP, when used in connection with net income attributable to common stock, are intended to provide useful information to investors and analysts as they evaluate our performance. EBITDA is defined as earnings before interest, taxes, depreciation and amortization, and adjusted EBITDA is defined as EBITDA adjusted for certain other items as described below. These measures should not be considered as an alternative to net income attributable to common stock or other financial measures of performance that are derived in accordance with GAAP. Management believes that the exclusion of these items from net income attributable to common stock enables it and its investors to more effectively evaluate our operations period over period and to identify operating trends that might not be apparent when including the excluded items.
As to certain of the items below, (i) non-cash stock-based compensation expense varies from period to period due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (ii) acquisition and integration costs vary from period to period depending on the level of our acquisition activity; (iii) equity in (earnings) losses of non-integral unconsolidated affiliates varies from period to period depending on the activity and financial performance of non-integral unconsolidated affiliates, including gain or loss on sales of investments accounted for using the equity method of accounting; (iv) asset impairment charges can vary from period to period depending on economic and other factors; and (v) change in fair value of contingent consideration liabilities varies from period to period depending on the performance in post-acquisition periods of certain acquired businesses. Because EBITDA and adjusted EBITDA, as defined, exclude some, but not all, items that affect net income attributable to common stock, such measures may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measure, net income

Remaining Performance Obligations and Backlog
A performance obligation is a promise in a contract with a customer to transfer a distinct good or service. Our remaining performance obligations represent management’s estimate of consolidated revenues that are expected to be realized from the remaining portion of firm orders under fixed price contracts not yet completed or for which work has not yet begun, which includes estimated revenues attributable to consolidated joint ventures and variable interest entities (VIEs), revenues from funded and unfunded portions of government contracts to the extent they are reasonably expected to be realized, and revenues from change orders and claims to the extent management believes they will be earned and are probable of collection.
We have also historically disclosed our backlog, a measure commonly used in our industry but not recognized under generally accepted accounting principles in the United States (GAAP).GAAP. We believe this measure enables management to more effectively forecast our future capital needs and results and better identify future operating trends that may not otherwise be apparent. We believe this measure is also useful for investors in forecasting our future results and comparing us to our competitors. Our remaining performance obligations are a component of backlog, which also includes estimated orders under master service agreements (MSAs),MSAs, including estimated renewals, and non-fixed price contracts expected to be completed within one year. Our methodology for determining backlog may not be comparable to the methodologies used by other companies.
As of September 30, 20202021 and December 31, 2019,2020, MSAs accounted for 61%62% and 53%63% of our estimated 12-month backlog and 69% and 61%70% of total backlog. The increase in MSAWe anticipate that subsequent to our acquisition of Blattner, MSAs may account for a lower percentage of our backlog resulted from our entry into several new multiyear MSAs with electric and gas utility customers during the three months ended September 30, 2020.because Blattner does not currently have a significant amount of backlog attributable to MSAs. Generally, our customers are not contractually committed to specific volumes of services under our MSAs, and most of our contracts can be terminated on short notice even if we are not in default. We determine the estimated backlog for these MSAs using recurring historical trends, factoring in seasonal demand and projected customer needs based upon ongoing communications. In addition, many of our MSAs are subject to renewal, and these potential renewals are considered in determining estimated backlog. As a result, estimates for remaining performance obligations and backlog are subject to change based on, among other things, project accelerations; project cancellations or delays, including but not limited to those caused by commercial issues, regulatory requirements, natural disasters, emergencies (including the ongoing COVID-19 pandemic) and adverse weather conditions; and final acceptance of change orders by customers. These factors can cause revenues to be realized in periods and at levels that are different than originally projected.

Liquidity and Capital Resources
Management monitors financial markets and national and global economic conditions for factors that may affect our liquidity and capital resources. We consider our investment policies related to cash and cash equivalents to be conservative in that we maintain a diverse portfolio of what we believe to be high-quality cash and cash equivalent investments with short-term maturities.
The extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on future developments, all of which are uncertain and cannot be predicted. However, based on our current business forecast for 2020, including revenue and earnings prospects and other cost management actions taken in response to market conditions, we anticipate that our cash and cash equivalents on hand, future cash flows from operations and existing borrowing capacity under our senior credit facility, which we increased and extended the maturity of during the three months ended September 30, 2020, as well as other available financing alternatives, will provide sufficient funds to enable us to meet our interest payment and debt repayment obligations, fund ongoing operating needs, facilitate our ability to pay any future dividends we declare, fund acquisitions or strategic investments that facilitate the long-term growth and sustainability of our business, and fund essential capital expenditures during 2020.
In addition, we may seek to access the capital markets from time to time to raise additional capital, increase liquidity as necessary, refinance or extend the term of our existing indebtedness or otherwise fund our capital needs. For example, during the three months ended September 30, 2020, we issued $1.00 billion aggregate principal amount of our senior notes, receiving proceeds of $986.7 million, net of the original issue discount, underwriting discounts and debt issuance costs. We utilized those proceeds, together with cash on hand, to voluntarily prepay the $1.21 billion of outstanding term loans under our senior credit facility. We also entered into an amendment to our senior credit facility that, among other things, increased the aggregate revolving commitments from $2.14 billion to $2.51 billion and extended the maturity date from October 31, 2022 to September 22, 2025. Our ability to access the capital markets in the future depends on a number of factors, including our financial performance and financial position, our credit rating, industry conditions, general economic conditions, our backlog, capital expenditure commitments, market conditions and market perceptions of us and our industry.

While the extent of the impact of the challenged energy market, as well as the COVID-19 pandemic, on our future operational and financial performance will depend on future developments and remains uncertain, based on our current business forecast for the next twelve months, we anticipate that our cash and cash equivalents on hand, future cash flows from operations, existing borrowing capacity under our senior credit facility and cashother available financing alternatives will provide sufficient funds during the next twelve months to enable us to fund ongoing operating needs, facilitate our ability to repurchase stock and cash equivalents at September 30, 2020 were as follows (in thousands):pay any future dividends we declare, fund acquisitions or strategic investments that facilitate the long-term growth and sustainability of our business, fund essential capital expenditures and make` payments related to obligations on our outstanding debt.

We may seek to access the capital markets from time to time to raise additional capital, increase liquidity as necessary, refinance or extend the term of our existing indebtedness, fund acquisitions or otherwise fund our capital needs. For example, as described further in Debt Instruments below, in connection with the financing of our acquisition of Blattner, in September 2021 we issued $1.50 billion aggregate principal amount of senior notes and received net proceeds of $1.48 billion, and in October 2021 we amended our senior credit facility to, among other things, provide for a new $750.0 million term loan facility and increase the aggregate revolving commitments of the lenders from $2.51 billion to $2.64 billion. The proceeds received from our issuance of senior notes in September 2021 represented a significant portion of the cash and cash equivalents balance at September 30, 2021, and such proceeds were utilized to fund the acquisition of Blattner on October 13, 2021. While our financial strategy and consistent performance have allowed us to maintain investment grade ratings subsequent to these financing transactions, our ability to access the capital markets in the future depends on a number of factors, including our financial performance and financial position, our credit ratings, industry conditions, general economic conditions, our backlog, capital expenditure commitments, market conditions and market perceptions of us and our industry.

Operating Activities
Cash flow from operating activities is primarily influenced by demand for our services and operating margins but is also influenced by working capital needs associated with the various types of services that we provide. Our working capital needs may increase when we commence large volumes of work under circumstances where project costs, primarily labor, equipment and subcontractors, are required to be paid before the associated receivables are billed and collected. Accordingly, changes within working capital in accounts receivable, contract assets and contract liabilities are normally related and are typically affected on a collective basis by changes in revenue due to the timing and volume of work performed and variability in the timing of customer billings and payments. Additionally, working capital needs are generally higher during the summer and fall due to increased demand for our services when favorable weather conditions exist in many of our operating regions. Conversely, working capital assets are typically converted to cash during the winter. These seasonal trends can be offset by changes in project timing due to delays or accelerations and other economic factors that may affect customer spending.spending, including market conditions or the impact of the COVID-19 pandemic.
Net cash provided by operating activities during the three and nine months ended September 30, 20202021 was negatively impacted primarily by increased working capital requirements, including with respect to progress on two large electric transmission projects in Canada, and the timing of the associated billings. Both of the projects were favorablynegatively impacted by delays related to the COVID-19 pandemic and unrelated wildfires, and one project was also impacted by an acceleration of the project timeline, all of which resulted in change orders and an increase in contract assets. Partially offsetting this negative impact was the favorable impact of increased earnings as compared to the three and nine months ended September 30, 2019.

Net cash provided by operating activities during the nine months ended September 30, 2019 included the payment of $112 million as a result of the exercise of on-demand advance payment and performance bonds in connection with the termination of the large telecommunications project in Peru, which is described in further detail in Legal Proceedings in Note 11 of the Notes to Condensed Consolidated Financial Statements in Item 1.

Net cash used in operating activities for the nine months ended September 30, 2019 was also impacted by higher working capital requirements, including mobilization and tooling costs, to support business growth and extended billing and collection cycles for certain utility customers.
Days sales outstanding (DSO) represents the average number of days it takes revenues to be converted into cash, which management believes is an important metric for assessing liquidity. A decrease in DSO has a favorable impact on cash flow from operating activities, while an increase in DSO has a negative impact on cash flow from operating activities. DSO is calculated by using the sum of current accounts receivable, net of allowance (which includes retainage and unbilled balances), plus contract assets less contract liabilities, divided by average revenues per day during the quarter. DSO at September 30, 20202021 was 82 days, which aligns with our historical average over the last five years of 80 days. DSO at September 30, 2019 was 9189 days, which was higher than DSO of 82 days at September 30, 2020 and our five-year historical average DSO of 82 days primarily due partially to aincreased working capital requirements related to progress on two large outstanding retainage balance associated with a larger electric transmission project, as well as billing process changes for certain customers thatprojects in Canada and the timing of the associated billings. Both of the projects were negatively impacted DSO throughout 2019by delays related to the COVID-19 pandemic and unrelated wildfires, and one project was also impacted by an acceleration of the project timeline, all of which resulted in change orders and an increase in contract assets.

To address the transition in financial markets away from the London Interest BankInterbank Offered Rate (LIBOR) by the end of 2021,, our senior credit facility agreementAmended Credit Agreement includes provisions related to thecustomary LIBOR benchmark replacement of LIBOR with a LIBOR Successor Rate (as defined in the credit agreementprovisions. The benchmark replacement for such facility), whichU.S. dollar-denominated loans may be a rate based on the secured overnight financing rate published by the Federal Reserve Bank of New York. If no LIBOR Successor Rate has been determined atYork or an alternate benchmark, subject to the timeterms and conditions set forth in the amended credit agreement. In certain circumstances, are present, the lenders’ obligation to make or maintain loans based on a Eurocurrency rate could be suspended, and loans in U.S. dollars would default to the Base Rate, which under such circumstances would equal the highest of (i) the Federal Funds Rate (as describeddefined in Senior Credit Facility within Note 7the amended credit agreement) plus 0.5% and (ii) the prime rate publicly announced by Bank of the Notes to Consolidated Financial Statements in Item 1. Financial Statements) rather than a rate using the Eurocurrency Rate.America, N.A.

billion. We had borrowed $600.0 million in term loans in October 2018 and $675.0 million in term loans in September 2019 and used the majority of the proceeds from such loans to repay then-outstanding revolving loans under the credit agreement. Term loans bore interest at rates generally consistent with the revolving loans borrowed in U.S. dollars, except that the additional amount over the Eurocurrency Rate was 1.125% to 1.875%, as determined based on our Consolidated Leverage Ratio. We made quarterly principal payments of $7.5 million on the term loan through September 2019 and $16.1 million on the term loans through June 2020.

The cash interest obligations related to the fixed-rate portion of our long-term debt are included in Long-term debt - cash interest; however, our $195.4$415.9 million of outstanding revolving loans under our senior credit facility bear interest at variable market rates. Assuming the principal amount outstanding and interest rate in effect for the revolving loans at September 30, 20202021 remained the same, the annual cash interest expense for such loans would be approximately $4.2$10.2 million, payable until September 22, 2025,October 8, 2026, the maturity date of the facility. See Liquidity and Capital Resource - Debt Instruments - Senior Credit Facility above for further information related to borrowings under the credit facility subsequent to September 30, 2021 associated with financing the cash portion of consideration related to the acquisition of Blattner.

Financial Statements, weWe have various contingencies and commitments that may require the use of cash in future periods.periods, including those set forth below. The Contractual Obligations table excludes the contingencies described below, as we are unable to accurately predict the timing and amount of any of the following contingent obligations.

Concentrations of Credit Risk
We are subject to concentrations of credit risk related primarily to our cash and cash equivalents and our net receivable position with customers, which includes amounts related to billed and unbilledUncollectible accounts receivable and contract assets net of advanced billings with the same customer. Substantially all of our cash and cash equivalents are managed by what we believe to be high credit quality financial institutions. In accordance with our investment policies, these institutions are authorized to invest cash and cash equivalents in a diversified portfolio of what we believe to be high quality cash and cash equivalent investments, which consist primarily of interest-bearing demand deposits, money market investments and money market mutual funds. Although we do not currently believe the principal amount of these cash and cash equivalents is subject to any material risk of loss, changes in economic conditions could impact the interest income we receive from these investments. In addition, we-We grant credit under normal payment terms, generally without collateral, to our customers, which include electric power and energy companies, governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States, Canada and Australia.customers. While we generally have certain statutory lien rights with respect to services provided, we are subject to potential credit risk related to business, economic and financial market conditions that affect these customers and locations, which has been heightened as a result of the unfavorable and uncertain economic and financial market conditions resulting from the ongoing COVID-19 pandemic and the significant decline in commodity prices and volatility in commodity production volumes.currently challenged energy market. Some of our customers have experienced significant financial difficulties (including bankruptcy), and customers may experience financial difficulties in the future. These difficulties expose us to increased risk related to collectability of billed and unbilled receivables and contract assets for services we have performed.
For example, certain customers within our Underground Utility and Infrastructure segment have experienced operational and/or financial difficulties. For additional information on January 29, 2019, PG&E Corporation and its primary operating subsidiary, Pacific Gas and Electric Company (together, PG&E), onethese matters, see Concentration of our largest customers, filed for bankruptcy protection under Chapter 11Credit Risk in Note 10 of the U.S. Bankruptcy Code, as amended. As Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of the bankruptcy filing date, we had $165 millionPart I of billed and unbilled receivables. During the bankruptcy case, the bankruptcy court approved the early assumption by PG&E of certain contracts with our subsidiaries. PG&E subsequently assumed its remaining contracts with our subsidiaries as part of its Chapter 11 plan of reorganization, which was confirmed by the bankruptcy court in June 2020. As of September 30, 2020, substantially all of Quanta’s pre-petition receivables had been paid. Additionally, a customer within our Pipeline and Industrial Infrastructure Services segment is currently experiencing liquidity challenges that have resulted in delayed payment of certain receivables associated with a project. While we believe these receivables are adequately secured by the project asset, we are continuing to monitor potential credit risk with respect to this Quarterly Report.
Lawsuits and other customers.
At September 30, 2020 and December 31, 2019, no customer represented 10% or more of our consolidated net receivable position. No customer represented 10% or more of our consolidated revenues for the three and nine months ended September 30, 2020 or the three months ended September 30, 2019. PG&E, a customer within our Electric Power Infrastructure Services segment, represented 10.5% of our consolidated revenues for the nine months ended September 30, 2019.
Legal Proceedings
legal proceedings - We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actionsbusiness, which typically seek, among other things, compensation for alleged personal injury, property damage, breach of contract, negligence or gross negligence, and/or property damages,environmental liabilities, wage and hour claims and other employment-related damages, punitive anddamages, consequential damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record a reserve when it is probable that a lossliability has been incurred and the amount of loss can be reasonably estimated. In addition, we disclose matters for which management believes a material loss is at least reasonably possible. See Note 1110 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report for additional information regarding litigation, claims and other legal proceedings.
Multiemployer Pension Plans
Collective bargaining agreements and multiemployer pension plan liabilities - Certain of our operating units are parties to collective bargaining agreements with unions that represent certain of their employees, and from time to time, we are a party to grievance and arbitration actions based on claims arising out of the collective bargaining agreements, which require the operating units tospecify that we pay specifiedcertain wages, provide certain benefits to union employees and contribute certain amounts to multiemployer pension plans and employee benefit trusts. Our multiemployer pension plan contribution rates generally are made to the plans on a “pay-as-you-go” basis based on our union employee payrolls. The location and number of union employees that we employ at any given time and the plans in which they may participate vary depending on our need for union resources in connection with our ongoing projects. Therefore,projects, and therefore we are unable to accurately predict our union employee payroll and the resulting multiemployer pension plan contribution obligations for future periods.
72


We Furthermore, we may also be required to make additional contributions to our multiemployer pension plans if they become underfunded and these additional contributions will be determined based on our union employee payrolls. Special funding and operational rulesor if we withdraw or are generally applicabledeemed to certain of these multiemployer plans that are classified as “endangered,” “seriously endangered” or “critical” status based on multiple factors. The amount, if any, that we may be obligated to contribute to these plans cannot be reasonably estimated and is not included in the above table due to uncertainty regarding the amount of future work involving covered union employees, future contribution levels and possible surcharges on plan contributions.
Furthermore, we may be subject to additional liabilities imposed by law as a result of our participation in multiemployer defined benefit pension plans, including in connection with a withdrawal or deemed withdrawalhave withdrawn from a plan or a plan beingis terminated or experiencingexperiences 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’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. We are not currently aware of any material withdrawal liabilities that have been incurred or asserted and that remain outstanding. However, our future contributionFor additional information on these obligations and potential withdrawal liability exposure could vary based on the investmentcontingencies, see Collective Bargaining Agreements and actuarial performanceMultiemployer Pension Plans in Note 10 of the multiemployer pension plansNotes to which we contribute and other factors, which could be negatively impacted as a result Condensed Consolidated Financial Statements in Item 1. Financial Statements of the unfavorable and uncertain economic and financial market conditions resulting from the ongoing COVID-19 pandemic and related issues. We have been subject to significant withdrawal liabilities in the past, including in connection with our withdrawal from the Central States, Southeast and Southwest Areas Pension Plan. To the extent we are subject to material withdrawal liabilities in the future, such liability could adversely affect our business, financial condition, resultsPart I of operations or cash flows.this Quarterly Report.
Bonds and Parent Guarantees
parent guarantees - Many customers, particularly in connection with new construction, require us to post performance and payment bonds. These bonds, which provide a guarantee that we will perform under the terms of a contract and pay our subcontractors and vendors. If we fail to perform,In certain circumstances, the customer may demand that theour surety make payments or provide services under the bond, and we must reimburse the surety for any expenses or outlays it incurs. We may also be required to post letters of credit in favor of the sureties, which would reduce the borrowing availability under our senior credit facility. Under our underwriting, continuing indemnity and security agreement with our sureties, we had also granted security interests in certain of our assets as collateral for our obligations to the sureties. However, in connection with the September 2020 amendment to the credit agreement, these security interests were automatically released. On September 22, 2020, we also entered into an amendment to the underwriting, continuing indemnity and security agreement that further documented this release and removed the collateral reinstatement provision in the agreement that would have applied in the event our corporate credit rating from either of Moody’s Investors Service, Inc. or Standard & Poor’s Financial Services LLC were to fall below an investment grade rating.
We have not been required to make any material reimbursements to our sureties for bond-related costs except in connection with the exercise of approximately $112.0 million of advance payment and performance bonds related to the terminated telecommunications project in Peru, which is described further in Legal Proceedings – Peru Project Dispute in Note 11 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements. To the extent further reimbursements are required, the amounts could be material and could adversely affect our consolidated business, financial condition, results of operations or cash flows. As of September 30, 2020, we are not aware of any outstanding material obligations for payments related to bond obligations.
Performance bonds expire at various times ranging from mechanical completion of a project 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 our bonded operating activity. As of September 30, 2020,2021 the total amount of theour outstanding performance bonds was estimated to be approximately $3.5$3.8 billion. Our 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 commitment under a performance bond generally extinguishes concurrently with the expiration of our related contractual obligation. The estimated cost to complete these bonded projects was approximately $1.4 billion as of September 30, 2020.
Additionally, from time to time, we guarantee certain obligations and liabilities of our subsidiaries that may arise in connection with, among other things, contracts with customers, equipment lease obligations, joint venture arrangements and contractor licenses. These guaranteeslicenses, and may cover all of the subsidiary’s unperformed, undischarged and unreleased obligations and liabilities under or in connection with the relevant agreement. For example, with respect to customer contracts, a guarantee may cover a variety ofadditional information on these obligations and liabilities arising during the ordinary course of the subsidiary’s business or operations, including, among other things, warrantypotential contingencies, see Bonds and breach of contract claims, third-party and environmental liabilities arising from the subsidiary’s work and for which it is responsible, liquidated damages, or indemnity claims. We are not aware of any claims under any of these guarantees that are material, except as set forthParent Guarantees in Legal Proceedings - Maurepas Project Dispute within

Note 1110 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statementsof Part I of this Quarterly Report. To
Insurance liabilities - Due to the extent a subsidiary incurs a material obligation or liability andnature of our operations, at any given time we have guaranteed the performance or paymenta significant amount of such liability, the recovery by a customer or other counterparty or a third party will not be limited to the assets of the subsidiary. As a result, responsibility under a guarantee could adversely affect our consolidated business, financial condition, results of operations and cash flows.
Insurance
Insurance Coverage. Losses under ouraccrued insurance programs are accrued based upon our 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 our 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.claims. As of September 30, 20202021 and December 31, 2019,2020, the gross amount accrued for insuranceemployer’s liability, workers’ compensation, auto liability, general liability, and group health claims totaled $304.6$316.8 million and $287.6 million, with $223.6 million and $212.9 million considered to be long-term and included in “Insurance and other non-current liabilities.” Related insurance recoveries/receivables as of September 30, 2020 and December 31, 2019 were $31.8 million and $35.1 million, of which $0.3 million and $0.3 million are included in “Prepaid expenses and other current assets” and $31.5 million and $34.8 million are included in “Other assets, net.”
We$319.5 million. Additionally, we renew our insurance policies on an annual basis, and therefore deductibles and levels of insurance coverage may change in future periods. In addition, insurers may cancel our coverage or determine to exclude certain items from coverage, or we may elect not to obtain certain types or incremental levels of insurance based on the potential benefits considered relative to the cost of such insurance, or coverage may not be available at reasonable and competitive rates. In any such event, our overall risk exposure would increase, which could negatively affect our results of operations, financial condition and cash flows. For example, due to the increased occurrence and future risk of wildfiresSee Insurance in California and other areas in the western United States, Australia and other locations, insurers have reduced coverage availability and increased the cost of insurance coverage for such events in recent years. As a result, our level of insurance coverage for wildfire events decreased, including in connection with our annual insurance renewals in the spring of 2020 and 2019, and our levels of coverage may not be sufficient to cover potential losses. Our third-party insurers could also decide to further reduce or exclude coverage for wildfires or other events in the future.
Hallen Acquisition Assumed Liability. As discussed in further detail in Legal Proceedings within Note 1110 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements, weof Part I of this Quarterly Report.
Indemnities and assumed certain contingent liabilities in- In connection with our acquisition transactions, we assume certain liabilities and obtain rights to indemnification from the acquisition of Hallen. Hallen’s liabilities associated with this matter are expected to be covered under applicable insurance policiessellers or contractual remedies negotiated by us with the former owners of Hallen. As of September 30, 2020, we had not recorded an accrual for any probable and estimable loss related to this matter. However, the ultimate amount of liability in connection with this matter remains subject to uncertainties associated with pending litigation, including, among other things, the apportionment of liability among the defendants and other responsible parties and the likelihood and amount of potential damages claims. As a result, this matter could result in a loss that is in excess of, or not covered by, such insurance or contractual remedies, which could have a material adverse effect on our consolidated results of operations and cash flows.
Contingent Consideration Liabilities
The liabilities recorded represent the estimated fair values of future amounts payable to the former owners of the acquired businesses and are estimated by management based on entity-specific assumptions that are evaluated on an ongoing basis. Because acquisition-related contingent considerationfor certain risks, liabilities are contingent upon future events, we include these liabilities in the contractual obligations table when the contingencies are resolved. We expect a significant portion of these liabilities to be settled by late 2020.
Aggregate fair values of these outstanding contingent consideration liabilities and their classification in the Consolidated Balance Sheets in Item 1. Financial Statements were as follows (in thousands):
 September 30, 2020December 31, 2019
Accounts payable and accrued expenses$68,466 $77,618 
Insurance and other non-current liabilities7,383 6,542 
Total contingent consideration liabilities$75,849 $84,160 
The measurement period for approximately $65.0 million of our outstanding contingent consideration liabilities was complete as of September 30, 2020. The remaining contingent consideration liabilities have an approximate aggregate fair value of $10.8 million, and the majority are subject to a maximum outstanding payment amount, which totaled $48.6 million as of September 30, 2020.
7465


The fair valuesobligations arising from their prior operations, such as performance, operational, safety, workforce or tax issues. However, we may not have discovered certain liabilities during due diligence and our indemnities may not cover all of these liabilities were primarily determined using a Monte Carlo simulation valuation methodology based on probability-weighted performance projectionsour exposure for such pre-acquisition matters or the indemnitors may be unwilling or unable to pay amounts owed to us. Accordingly, we may incur expenses that are not reimbursed, and other inputs, including a discount rate and an expected volatility factor for each acquisition. The inputs for the remaining liabilities include an expected volatility factor of 30.0% based on historical asset volatility of selected guideline public companies. Depending on contingent consideration payment terms, the present values of the estimated payments are discounted based on a risk-free rate and/or our cost of debt, which ranged from 0.1% to 3.9% as of September 30, 2020 and had a weighted average of 2.4% based on fair value at acquisition. The fair value determinations incorporate significant inputs not observable in the market. Accordingly, the level of inputs used for these fair value measurements is the lowest level (Level 3), as further describedsuch amounts could be material. See Indemnities in Note 210 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements. Significant changes in any of Part I of this Quarterly Report for further discussion related to these assumptions could result in a significantly higher or lower potential liability.contingencies.
Our aggregate contingent consideration liabilities can change dueLiabilities related to additional business acquisitions, settlement of outstanding liabilities, changes in the fair value of amounts owed based on performance in post-acquisition periods and accretion in present value. During the three and nine months ended September 30, 2020, we recognized net increases of $0.1 million and $0.6 million in the fair value of our aggregate contingent consideration liabilities. During the three and nine months ended September 30, 2019, we recognized net increases of $3.8 million and $8.1 million in the fair value of our aggregate contingent consideration liabilities. These changes are reflected in “Change in fair value of contingent consideration liabilities” in our condensed consolidated statements of operations. We settled certain contingent consideration liabilities with $11.0 million of cash payments and the issuance of 4,277 shares of Quanta common stock during the nine months ended September 30, 2020. The majority of the cash payments have been classified as a financing activity, with the remainder classified as an operating activity, in our condensed consolidated statements of cash flows for the nine months ended September 30, 2020.
Deferred Compensation Plans
deferred compensation plans - We maintain nonqualifiednon-qualified deferred compensation plans pursuant to which non-employee directors and certain key employees may defer receipt of some or all of their cash compensation and/or settlementcompensation. As of certain stock-based awards, subject to certain limitations. These plans are unfunded and unsecured compensation arrangements. Individuals participating in these plans may allocate deferred cash amounts among a group of notional accounts that mirror the gains and losses of various investment alternatives. Generally, participants receive distributions of deferred balances based on predetermined payout schedules or other events.
The plan covering key employees provides for employer matching contributions for certain officers and employees whose benefits under the 401(k) plan are limited by federal tax law. We may also make discretionary employer contributions to such plan. Matching contributions vest immediately, and discretionary employer contributions may be subject to a vesting schedule determined at the time of the contribution, provided that vesting accelerates upon a change in control or the participant’s death or retirement. All matching and discretionary employer contributions, whether vested or not, are forfeited upon a participant’s termination of employment for cause or upon the participant engaging in competition with us or any of our affiliates. 
We made matching contributions to the eligible participants’ accounts under the deferred compensation plans of $0.2 million and $0.2 million during the three months ended September 30, 2020 and 2019 and $1.0 million and $0.9 million during the nine months ended September 30, 2020 and 2019. We made no discretionary contributions during the nine months ended September 30, 2020 and 2019. At September 30, 20202021 and December 31, 2019,2020, obligations under these plans, including amounts contributed by us, were $51.4$69.1 million and $47.3 million$58.2 million.��These plans are unfunded and were included unsecured compensation arrangements, and the amount of the obligations can fluctuate based on the market value of participants’ investment elections under the plan. See Deferred Compensation Plans in “Insurance and other non-current liabilities”Note 10 of the Notes to Condensed Consolidated Financial Statements in our condensed consolidated balance sheets. We maintain investments to provideItem 1. Financial Statements of Part I of this Quarterly Report for future obligationsfurther discussion related to these deferred compensation plans. At September 30, 2020 and December 31, 2019, these investments were primarily comprised
Undistributed earnings of company-owned life insurance policies, had fair market values of $52.2 million and $45.8 million and were included in “Other assets, net” in our condensed consolidated balance sheets.
Undistributed Earnings of Foreign Subsidiaries and Unrecognized Tax Benefits
foreign subsidiaries - We generally do not provide for taxes related to undistributed earnings of our foreign subsidiaries because such earnings either would not be taxable when remitted or they are considered to be indefinitely reinvested. Weand we could also be subject to additional foreign withholding taxes if we were to repatriate cash that is indefinitely reinvested outside the United States, butStates. However, we do not expect such amountsamount to be material.
QuantaUnrecognized tax benefits and certainvaluation allowance on deferred tax assets - As of September 30, 2021, the total amount of unrecognized tax benefits relating to uncertain tax positions was $40.6 million. Our consolidated federal income tax return for the tax year 2019 is currently under examination by the IRS, and our consolidated federal income tax returns for tax years 2017, 2018, and 2020 remain open to examination by the IRS, as these statute of limitations periods have not yet expired, and various state and foreign tax returns filed by us and our subsidiaries for multiple periods remain under examination by various U.S. state, Canadian and other foreign tax authorities for multiple periods.authorities. We believe it is reasonably possible that within the next 12 months unrecognized tax benefits may decrease by up to $10.0$13.3 million as a result of settlement of these examinations or as a result of the expiration of certain statute of limitations periods.

Additionally, we regularly evaluate valuation allowances established for deferred tax assets for which future realization is uncertain, including in connection with changes in tax laws, and we may not realize deferred tax assets to the extent estimated. See

Residual Value Guarantees - We have guaranteed the residual value under certain of our letters of creditequipment operating leases, agreeing to pay any difference between this residual value and the associated feesfair market value of the underlying asset at the date of lease termination. Due to the nature of our operations, at any given time we have a significant amount of outstanding residual value guarantees, and our borrowings under our senior credit facility, see as of September 30, 2021 the maximum guaranteed residual value of this equipment was $886.9 million. While we believe that no significant payments will be made as a result of these residual value guarantees, there can be no assurance that significant payments will not be required in the future.
Liquidity and Capital ResourcesInvestment commitment — Debt Instruments above.- As of September 30, 2021, we had committed to contribute $13.6 million for certain investments, but the timing of the contributions has not yet been determined.
Off-Balance Sheet TransactionsArrangements
As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected in our balance sheets. Our significant off-balance sheet transactions include certain obligations relating to our investments and joint venture arrangements; short-term, non-cancelable leases and leases that have not yet commenced; letters of credit obligations; surety guarantees related to bonds; committed expenditures for the purchase of equipment; and certain multiemployer pension plan liabilities. See Contractual Obligations and Contingencies above and Note 1110 of the Notes to Condensed Consolidated Financial Statements in Item 1.

Critical Accounting Estimates and Policies Update
The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP.the rules of the SEC. Certain information and footnote disclosures normally included in annual financial statements, which are prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the condensed consolidated financial statements are published and the reported amounts of revenues and expenses recognized during the periods presented. We review all significant estimates affecting our condensed consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on our 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. There can be no assurance that actual results will not differ from those estimates. Management has reviewed its development and selection of critical accounting estimates with the audit committee of our Board of Directors. Our accounting policies are primarily described in Note 2 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data of Part II of our 2020 Annual Report and, to a lesser extent, in Note 2 of the Notes to Condensed Consolidated Financial Statements in Item 1.

Item 3.Quantitative and Qualitative Disclosures about Market Risk.
The information in this section should be read in connection with the information on financial market risk related to changes in interest rates and currency exchange rates in Item 7A. Quantitative and Qualitative Disclosures About Market Risk of Part II of our 20192020 Annual Report. Our primary exposure to market risk relates to unfavorable changes in concentration of credit risk, interest rates and currency exchange rates.
Credit Risk. We are subject to concentrations of credit risk related to our cash and cash equivalents and net receivable position with customers, which includes amounts related to billed and unbilled accounts receivable and contract assets net of advanced billings with the same customer. Substantially all of our cash and cash equivalents are managed by what we believe to be high credit quality financial institutions. In accordance with our investment policies, these institutions are authorized to invest cash and cash equivalents in a diversified portfolio of what we believe to be high-quality investments, which primarily include interest-bearing demand deposits, money market investments and money market mutual funds. Although we do not currently believe the principal amounts of these cash and cash equivalents are subject to any material risk of loss, changes in economic conditions could impact the interest income we receive from these investments.
In addition, we grant credit under normal payment terms, generally without collateral, and therefore are subject to potential credit risk related to our customers’ inability to pay for services provided. For example, in January 2019 one of our largest customers, PG&E, filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, as amended. See Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations Concentration of Credit Risk for additional information regarding this bankruptcy matter. Furthermore, the risk of nonpayment may be heightened as a result of depressed economic and financial market conditions, including in connection with the ongoing COVID-19 pandemic and the significant decline in commodity prices and volatility in commodity production volumes.currently challenged energy market. We believe the concentration of credit risk related to billed and unbilled receivables and contract assets is limited because of the diversity of our customers, and we perform ongoing credit risk assessments of our customers and financial institutions and in some cases obtain collateral or other security from our customers. For example, certain customers within our Underground Utility and Infrastructure Solutions segment have encountered operational and/or financial difficulties. For additional information regarding these matters, see Revenue Recognition - Current and Long-Term Accounts Receivable and Allowance for Credit Losses in Note 2 and Concentrations of Credit Risk in Note 10 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
Interest Rate Risk. As of September 30, 2020,2021, we had no derivative financial instruments to manage interest rate risk. As such, we were exposed to earnings and fair value risk due to changes in interest rates with respect to our long-term obligations.variable rate debt, which is comprised of borrowings under the credit agreement for our senior credit facility. As of September 30, 2020,2021, the fair value of our variable rate debt of $195.4$415.9 million approximated book value. Ourvalue, and our weighted average interest rate on our variable rate debt for the three months ended September 30, 20202021 was 1.57%2.13%. The annual effect on our pretax earnings of a hypothetical 50 basis point increase or decrease in variable interest rates would be approximately $1.0$2.1 million based on our September 30, 20202021 balance of variable rate debt.
Additionally, the transition in financial markets away from the LIBOR beginning in 2021 may lead to additional volatility in interest rates and could cause our debt which is comprised service obligations to increase significantly as further described in Liquidity and Capital Resources - Debt Instruments in Item 2. Management’s Discussion and Analysis of borrowings under the credit agreement for our senior credit facility.Part I of this Quarterly Report.

Foreign Currency Risk. The U.S. dollar is the functional currency for the majority of our operations, which are primarily located within the United States. The functional currency for our foreign operations, which are primarily located in Canada and Australia, is typically the currency of the country in which the foreign operating unit is located. Accordingly, our financial performance is subject to fluctuation due to changes in foreign currency exchange rates relative to the U.S. dollar. During the three and nine months ended September 30, 2020,2021, revenues from our foreign operations accounted for 12.9%13.7% and 14.3%15.3% of our consolidated revenues. Fluctuations in foreign currency exchange rates during the three and nine months ended September 30, 20202021 caused decreasesa net increase of approximately $1$21 million and $23$99 million inrelated to foreign revenues when compared to the three and nine months ended September 30, 2019.2020.
We are also subject to foreign currency risk with respect to sales, purchases and borrowings that are denominated in a currency other than the respective functional currencies of our operating units. To minimize the risk from changes in foreign currency exchange rates, we may enter into foreign currency derivative contracts to hedge our foreign currency risk on a cash flow basis. There wereWe had no outstanding foreign currency derivative contracts at September 30, 2020.2021.
We also have foreign exchange risk related to cash and cash equivalents in foreign banks. Based on the balance of cash and cash equivalents in foreign banks of $27.9$31.2 million as of September 30, 2020,2021, an assumed 5% adverse change to foreign exchange rates would result in a fair value decline of $0.7$1.2 million.

Item 4.Controls and Procedures.
Attached as exhibits to this Quarterly Report on Form 10-Q are certifications of Quanta’s Chief Executive Officer and Chief Financial Officer that are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the Exchange Act). This item includes information concerning the controls and controls evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

Evaluation of Disclosure Controls and Procedures
Our management has established and maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, such as this Quarterly Report, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. The disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
As of the end of the period covered by this Quarterly Report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of the Exchange Act, as such disclosure controls and procedures are defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, these officers have concluded that, as of September 30, 2020,2021, our disclosure controls and procedures were effective to provide reasonable assurance of achieving their objectives.
Evaluation of Internal Control over Financial Reporting
No change in our internal control over financial reporting occurred during the quarter ended September 30, 20202021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Design and Operation of Control Systems
Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because of simple errors or mistakes. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of
68

compliance with policies or procedures.

PART II — OTHER INFORMATION
Item 1.  Legal Proceedings.
We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, property damage, breach of contract, and/negligence or property damages,gross negligence, environmental liabilities, wage and hour claims and other employment-related damages, punitive damages, consequential damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record a reserve when it is probable that a loss has been incurred and the amount of loss can be reasonably estimated. In addition, we disclose matters for which management believes a material loss is at least reasonably possible. See Note 1110 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report, which is incorporated by reference in this Item 1, for additional information regarding litigation, claims and other legal proceedings.
Item 1A.  Risk Factors.
Our business is subject to a variety of risks and uncertainties that are difficult to predict and many of which are outside of our control. For a detailed discussion of the risks that affect our business, refer to Item 1A. Risk Factors of Part I of our 20192020 Annual Report. As of the date of this filing, there have been no material changes to the risk factors previously described in our 20192020 Annual Report, except as set forth below with respect to our acquisition of Blattner and except that the potential effects of the COVID-19 pandemicacquisition of Blattner, and the financing thereof, may also have the effect of heightening many of thecertain other risks described in our 20192020 Annual Report
Report. The matters specifically identified are not the only risks and uncertainties facing our company, and additional risks and uncertainties not known to us or not specifically identified may also impair our business. If any of these risks and uncertainties occur, our business, financial condition, results of operations and cash flows could be negatively impacted, which could negatively impact the value of an investment in our company.
The effectsWe may not realize the anticipated benefits and synergies from our acquisition of the COVID-19 pandemic and related economic repercussions have materially affected how we and our customers are operating our businesses, and the duration and extent to which this will negatively impact our future results of operations and overall financial performance remains uncertain.Blattner.
The COVID-19 pandemic has negatively impacted the global economy, disrupted consumer spending and global supply chains, and created significant volatility and disruptionsuccess of financial markets. We have experienced some resulting disruptions to our business operations, and we expect the COVID-19 pandemic could continue to have a material adverse impactacquisition of Blattner will depend, in part, on our business and financial performance. The extent of the impact of the COVID-19 pandemic on our business and financial performance, including our ability to executerealize the anticipated benefits from successfully integrating Blattner’s business. We plan on devoting substantial management attention and resources to integrating our near-term and long-termBlattner’s business strategiespractices and initiativesoperations so that we can fully realize the anticipated benefits of the acquisition. Nonetheless, the business and assets acquired may not be successful, achieve the anticipated financial results or continue to grow at the same rate as when operated independently or may require greater resources and investments than originally anticipated. The acquisition of Blattner could also result in the expectedassumption of unknown or contingent liabilities. Potential difficulties we may encounter in the integration process include the following:
the inability to successfully integrate Blattner’s business in a manner that permits us to achieve the strategic operational benefits, additional opportunities with customers, reputational benefits or cost savings anticipated to result from the acquisition, which would result in some anticipated benefits of the acquisition not being realized in the time frame will depend on future developments, including currently anticipated, or at all;
the durationfailure to integrate operations and severityinternal systems, programs and controls;
the inability to successfully realize the anticipated value from some of Blattner’s assets;
lost revenues and lost or damaged commercial relationships;
the complexities and difficulties associated with our decentralized management structure;
the additional complexities of integrating a business with a different customer base, markets, history, culture and strategy;
the failure to retain key employees of either of the pandemic, two companies that may be difficult to replace;
the resulting governmentaldisruption of our ongoing businesses or inconsistencies in our services, standards, controls, procedures and other measures implementedpolicies;
potential unknown, unforeseen or greater than expected liabilities and expenses associated with the acquired business;
changes in estimates related to address the pandemicrevenues and the developmentcosts associated with Blattner's ongoing contracts with customers; and availability of effective treatments and vaccines, which are uncertain and cannot be predicted.
We have been negatively impacted by the COVID-19 pandemicperformance shortfalls as a result of the shelter-in-place restrictions and work disruptions in somediversion of our service areas creating disruptions to portions of our operations, particularly in major metropolitan markets that have been meaningfully impactedmanagement’s attention caused by the pandemic and in Latin America. We have also experienced permitting and regulatory delays attributable to the COVID-19 pandemic. Restrictions on operations related to industrial facilities have also resulted in suspensions and delays related to our high-pressure and critical-path turnaround services to the downstream and midstream energy markets. In addition to these current dynamics, the COVID-19 pandemic may create or exacerbate risks related to our operations and regulatory and compliance matters, including as a result of:
evolving governmental guidance or requirements, including travel and movement restrictions, that continue to impact our ability to perform services or complete projects in accordance with required delivery schedules, which could result in additional costs or penalties (e.g., liquidated damages);integrating Blattner’s operations.
additional delays with respect to permitting and regulatory matters;
additional project deferrals, delays, and cancellations and changes in customer spending patterns and strategic plans as a result of, among other things, prolonged decreases in energy demand, lack of available financing for our customers’ businesses or termination of, or force majeure events arising under, existing customer agreements;
governmental guidance or requirements, including work-from-home policies, or potential illness that negatively impact the availability or productivity of our key personnel or a significant number of employees or cause other disruptions to our business, corporate governance or financial reporting processes;
increased payment risk associated with customers experiencing financial difficulties (including bankruptcy) and an increase in disputes with customers relating to billing and payment under contracts and change orders;
8270


potential liabilitiesIn addition, laws and reputational harmregulations related to occupational health and safety matters associated with COVID-19;
our inability to execute our business strategy, including with respect to certain capital investments such as acquisitions, investments and service offering expansions;
limitations on the ability of our suppliers, vendors and subcontractors to perform;
asset impairment charges related to property and equipment, goodwill, other intangible assets, other long-lived assets and investments;
additional costs associated with restructuring, severance and related matters, potential mandated increases in pay for critical infrastructure workers or other increased employment-related costs (e.g., workers’ compensation insurance claims); and
an increase in cyber-attacks and attempted intrusions into our information technology systems as a result of, among other things, increased reliance on such systems.
Additionally, oil demand has significantly deteriorated as a result of the COVID-19 pandemic and corresponding preventative measures taken around the world to mitigate the spread of the COVID-19. At the same time, prior increases in production of oil by certain producers created a significant surplus in the supply of oil. Therenewable energy could adversely impact of these events has resulted in downward pressure on commodity prices, which has negatively impacted, and may continue to negatively impact, certain services within our Pipeline and Industrial Infrastructure Services segment and has resulted in impairment losses of $8.7 million related to certain non-integral equity method investments and may result in future impairment losses associated with goodwill and other intangible assets. Lower commodity prices and production volumes, or perceived risk thereof, can also result in decreased or delayed spending by our customers, including with respect to larger pipeline and industrial projects. A decline in commodity prices, production or the development of resource plays can also negatively impact certain portions of our Electric Power Infrastructure Services segment.
Furthermore, given the uncertain duration of the COVID-19 pandemic, we may face potential challenges related to financing our business in the future. During the three months ended September 30, 2020, we completed the issuance of $1.00 billion aggregate principal amount of 2.900% Senior Notes due October 1, 2030, which allowed us to prepay the outstanding term loans under our senior credit facility, and amended our senior credit facility to, among other things, increase the aggregate revolving commitments from $2.14 billion to $2.51 billion and extended the maturity date to September 2025. While we do not currently anticipate the need for significant financing initiatives in the near term, fluctuations in economic, political and market conditions could limit our ability to further increase commitments under our senior credit facility, which is dependent on additional commitments from new or existing lenders, or secure additional financing on acceptable terms through capital markets or otherwise.
As a result of these factors, the extent of the impact of the COVID-19 pandemic on our business is highly uncertain and difficult to predict. At this point, we cannot reasonably estimate the duration and severity of the COVID-19 pandemic, or its ultimate impact on our business, financial condition, results of operations and growth prospects of Blattner, including, among other things, changes to legislation and regulation that mandate percentages of power to be generated from renewable sources, require utilities to meet reliability standards, and encourage installation of new electric power transmission and renewable energy generation facilities. Furthermore, supply chain and other logistical difficulties, as well as sourcing restrictions on materials necessary for certain renewable energy projects, could negatively impact renewable energy customers and delay or cash flows.jeopardize the viability of certain renewable energy projects in the future. For example, delays in the transportation of materials for renewable projects (e.g., solar panels) from ports to project sites, as well as sourcing restrictions on certain solar project materials produced in China, could increase the pricing of such materials, and negatively impact Blattner’s customers and certain solar infrastructure projects in the near term. Any of these risks could adversely affect our ability to fully realize the anticipated benefits of our acquisition of Blattner within the expected timeframe or at all or such benefits may take longer to realize or cost more than expected, which could adversely affect our business, financial condition, results of operations and growth prospects.
We have incurred, and expect to continue to incur, substantial expenses related to our acquisition of Blattner.
We have incurred, and expect to continue to incur, substantial expenses in connection with the acquisition of Blattner and integrating the business, operations, practices, policies and procedures of Blattner. While we assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond our and Blattner’s control that could affect the total amount or the timing of their integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. The overall expenses in connection with the acquisition are expected to be significant, although the aggregate amount and timing of such charges are uncertain at present.
