NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Business, Basis of Presentation and Significant Accounting Policies

Nature of the Business

MasTec, Inc. (collectively with its subsidiaries, “MasTec” or the “Company”) is a leading infrastructure construction company operating mainly throughout North America across a range of industries. The Company’s primary activities include the engineering, building, installation, maintenance and upgrade of communications, energy and utility infrastructure, such as: wireless, wireline/fiber and satellite communications; petroleum and natural gas pipeline infrastructure; electrical utility transmission and distribution; power generation; and industrial infrastructure. MasTec’s customers are primarily in these industries. MasTec reports its results under five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Power Generation and Industrial; and (5) Other.

Basis of Presentation

The accompanying condensed unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in the annual audited consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying condensed consolidated balance sheet as of December 31, 2014 is derived from the Company’s audited financial statements as of that date. Because certain information and footnote disclosures have been condensed or omitted, these condensed unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2014 contained in the 2014 Form 10-K. In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included. Certain prior year amounts have been reclassified to conform to the current period presentation. Interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The Company believes that the disclosures made in these condensed unaudited consolidated financial statements are adequate to make the information not misleading. In these condensed unaudited consolidated financial statements, “$” means U.S. dollars unless otherwise noted.

Principles of Consolidation

The accompanying condensed unaudited consolidated financial statements include MasTec, Inc. and its subsidiaries and include the accounts of all majority owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest. Other parties’ interests in companies for which MasTec exercises control and has a controlling financial interest are reported as non-controlling interests within equity. Net income or loss attributable to non-controlling interests is reported as a separate line item below net income or loss. The Company’s investments in entities in which the Company does not have a controlling interest, but for which it has the ability to exert significant influence, are accounted for using the equity method of accounting. Equity method investments are recorded as other long-term assets in the condensed unaudited consolidated balance sheets. Income or loss from these investments is recorded within other income or expense in the condensed unaudited consolidated statements of operations. The cost method is used for investments in entities in which the Company does not have the ability to exert significant influence. All significant intercompany balances and transactions have been eliminated in consolidation. The assets and liabilities of foreign subsidiaries with a functional currency other than the U.S. dollar are translated into U.S. dollars at period-end exchange rates, with resulting translation gains or losses accumulated within other comprehensive income or loss. Revenue and expenses are translated into U.S. dollars at average rates of exchange during the applicable period. Substantially all of our foreign operations use the local currency as the functional currency. Gains or losses resulting from transactions executed in a foreign currency are included in other income or expense, net. The Company does not currently have subsidiaries that operate in highly inflationary environments. The results of operations and financial position of any discontinued operations are aggregated and presented separately from the Company’s continuing operations in the condensed unaudited consolidated financial statements for all periods presented.

Restatement of Previously Reported Condensed Unaudited Consolidated Financial Statements

As disclosed in the 2014 Form 10-K, the Company restated its condensed unaudited consolidated financial statements for the three and six month periods ended June 30, 2014 and presented these restated results in Note 2 - Independent Investigation of the Audit Committee and Related Restatements of the 2014 Form 10-K. The condensed unaudited consolidated financial statements, along with the related notes thereto as of and for the three and six month periods ended June 30, 2014 reflect these restatements. The restatement adjustments had the following effects on the 2014 periods:


•	An increase in revenue of $2.7 million for the three month period ended June 30, 2014, and a decrease in revenue of $3.5 million for the six month period ended June 30, 2014, associated with changes in cost-to-complete estimates on projects accounted for under the percentage-of-completion method, primarily in the Electrical Transmission segment;


•	Immaterial adjustments in costs of revenues, excluding depreciation and amortization, and other income, net, for the three and six month periods ended June 30, 2014;


•	An increase in income tax expense of $1.0 million for the three month period ended June 30, 2014, and a decrease in income tax expense of $1.4 million for the six month period ended June 30, 2014, representing the tax effects of the adjustments;


•	An increase in net income from continuing operations of $1.7 million for the three month period ended June 30, 2014, and a decrease in net income from continuing operations of $2.3 million for the six month period ended June 30, 2014; and


•	An increase in basic and diluted earnings per share of $0.02 each for the three month period ended June 30, 2014, and a decrease in basic and diluted earnings per share of $0.03 each for the six month period ended June 30, 2014.

In addition, there were the following balance sheet effects:


•	a decrease in costs and earnings in excess of billings of $4.4 million from cost-to-complete estimate changes, primarily in the Electrical Transmission segment;


•	a reclassification adjustment associated with cost-to-complete estimates that decreased costs and earnings in excess of billings and other current liabilities by $4.1 million;


•	a decrease in billings in excess of costs and earnings of $0.8 million; and


•	an increase in current taxes receivable of $1.4 million, as well as other immaterial adjustments within various segments.

Investments in Affiliates and Other Entities

In the ordinary course of business, the Company enters into various investment arrangements, which may include equity or other interests in business entities, including contractual joint ventures or other forms of equity participation. These investment arrangements may include financing arrangements, such as the extension of loans. See Note 3 - Acquisitions and Note 5 - Fair Value of Financial Instruments for discussion pertaining to certain of the Company’s cost and equity method investments and other investment arrangements. In connection with certain of these investment arrangements, the Company provides infrastructure construction services to or through its equity investees and/or contractual joint ventures. Management determines whether such investment arrangements involve a variable interest entity (“VIE”) based on the characteristics of the particular entity. If an entity is determined to be a VIE, then management determines if the Company is the primary beneficiary of the entity and whether or not consolidation of the VIE within the Company's financial statements is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the primary activities of the VIE and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, which, in either case, could be significant to the VIE. If management determines that the Company is the primary beneficiary of a VIE, then the VIE would be consolidated, and the other party’s equity interest in the VIE would be accounted for as a non-controlling interest. As of June 30, 2015, the Company determined that certain of its investment arrangements were VIEs, but that it was not the primary beneficiary of its VIEs. In arrangements in which the Company has an undivided interest in the assets, liabilities, revenues and profits or losses of an unincorporated entity, such amounts are consolidated on a basis proportional to the Company’s ownership interest in the unincorporated entity.

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Key estimates include: the recognition of revenue and project profit or loss (which the Company defines as project revenue, less project costs of revenue, including depreciation), in particular, on long-term construction contracts, or other projects accounted for under the percentage-of-completion method, for which the recorded amounts require estimates of costs to complete projects, ultimate project profit and the amount of contract price adjustments that are probable; allowances for doubtful accounts; estimated fair values of goodwill and intangible assets and liabilities, acquisition-related contingent consideration and investments in cost and equity method investees; asset lives used in computing depreciation and amortization; accrued self-insured claims; share-based compensation; accounting for income taxes; and the estimated impact of contingencies and ongoing litigation. While management believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole, actual results could differ from those estimates and such differences could be material to the condensed unaudited consolidated financial statements.

Significant Accounting Policies

Revenue Recognition

Revenue is derived from projects performed under master and other service agreements as well as from fixed price contracts for specific projects or jobs requiring the construction and installation of an entire infrastructure system or specified units within an entire infrastructure system. The Company frequently provides maintenance, installation and repair work under unit price or fixed price master service or other service agreements that are renewed on a periodic basis. Revenue and related costs for master and other service agreements billed on a time and materials basis are recognized as the services are rendered. Revenue derived from projects performed under master service and other service agreements totaled 45% and 50% of revenue for the three month periods ended June 30, 2015 and 2014, respectively, and totaled 48% and 52% of revenue, respectively, for the six month periods ended June 30, 2015 and 2014. The Company also performs services under master and other service agreements on a fixed fee basis, under which MasTec furnishes specified units of service for a fixed price per unit of service and revenue is recognized as the services are rendered. Revenue from fixed price contracts provides for a fixed amount of revenue for the entire project, subject to certain additions for changed scope or specifications. Revenue from these contracts, as well as for certain projects pursuant to master and other service agreements, is recognized using the percentage-of-completion method, under which the percentage of revenue to be recognized for a given project is measured by the percentage of costs incurred to date on the contract to the total estimated costs for the contract. Such contracts provide that the customer accept completion of progress to date and compensate the Company for services rendered, which may be measured in terms of costs incurred, units installed, hours expended or some other measure of progress. Contract costs include all direct materials, labor and subcontracted costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and the operational costs of capital equipment (excluding depreciation). Much of the materials associated with the Company’s work are customer-furnished and are therefore not included in contract revenue and costs.

The estimation process for revenue recognized under the percentage-of-completion method is based on the professional knowledge and experience of the Company’s engineers, project managers and financial professionals. Management reviews estimates of contract revenue and costs on an ongoing basis. Changes in job performance, job conditions and final contract settlements are factors that influence management’s assessment of total

contract value and total estimated costs to complete those contracts and, therefore, the Company’s profit recognition. Changes in these factors may result in revisions to costs and income, and their effects are recognized in the period in which the revisions are determined, which could materially affect the Company’s results of operations in the period in which such changes are recognized. Excluding the effects of previously disclosed first quarter 2015 project losses of $16.0 million on a Canadian wind project and $5.5 million on a non-controlled proportionately consolidated Canadian joint venture, project profit was affected by less than 5% for both the six month periods ended June 30, 2015 and 2014 as a result of changes in contract estimates included in projects that were in process as of December 31, 2014 and 2013, respectively. Provisions for losses on uncompleted contracts are made in the period in which such losses are determined to be probable and the amount can be reasonably estimated. The majority of fixed price contracts are generally completed within one year.

The Company may incur costs subject to change orders, whether approved or unapproved by the customer, and/or claims related to certain contracts. Management determines the probability that such costs will be recovered based upon engineering studies and legal opinions, past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer. The Company treats project costs as a cost of contract performance in the period incurred if it is not probable that the costs will be recovered, or defers costs and/or recognizes revenue up to the amount of the related cost if it is probable that the contract price will be adjusted and can be reliably estimated. As of June 30, 2015 and December 31, 2014, the Company had approximately $82 million and $87 million, respectively, of change orders and/or claims that had been included as contract price adjustments on certain contracts that were in the process of being resolved in the normal course of business, including through negotiation, arbitration and other proceedings. These contract price adjustments, which are included within costs and earnings in excess of billings, or billed accounts receivable as appropriate, represent management’s best estimate of contract revenue that has been or will be earned and that management believes is probable of collection. As of both June 30, 2015 and December 31, 2014, outstanding change orders and/or claims were derived from contracts in the Electrical Transmission and Oil and Gas segments. The Company actively engages in substantive meetings with these customers to complete the final approval process, and expects these processes to be completed within one year. The amounts ultimately realized upon final acceptance by its customers could be higher or lower than such estimated amounts.

Billings in excess of costs and estimated earnings on uncompleted contracts are classified as current liabilities. Costs and estimated earnings in excess of billings, or work in process, is classified within current assets for the majority of the Company’s projects. Work in process on contracts is based on work performed but not yet billed to customers as per individual contract terms.

Except for adoption of the accounting pronouncement discussed below, there have been no material changes to the significant accounting policies set forth in the 2014 Form 10-K.

New Accounting Pronouncements

Accounting Standards Not Yet Adopted

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 requires inventory measured using any method other than last-in, first out (“LIFO”) or the retail inventory method to be subsequently measured at the lower of cost or net realizable value, rather than at the lower of cost or market. Under this ASU, subsequent measurement of inventory using the LIFO and retail inventory method is unchanged. ASU 2015-11 is effective prospectively for fiscal years, and for interim periods within those years, beginning after December 15, 2016. Early application is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 provides guidance for determining whether a cloud computing arrangement includes a software license and requires that all software licenses within the scope of Subtopic 350-40 be accounted for in a manner consistent with other licenses of intangible assets. ASU 2015-05 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. Retrospective application is permitted for all relevant prior periods. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented as a direct deduction from the carrying amount of the debt, consistent with debt discounts. ASU 2015-03 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. Retrospective application is required for all relevant prior periods. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 changes the evaluation that a reporting entity must perform to determine whether it should consolidate certain types of legal entities, reduces the number of consolidation models and places emphasis on risk of loss when determining a controlling financial interest. Under ASU 2015-02, all entities are within the scope of Accounting Standards Codification (“ASC”) Subtopic 810, Consolidation, including limited partnerships and similar legal entities, unless a scope exception applies. The presumption that a general partner controls a limited partnership has been eliminated. In addition, fees paid to decision makers that meet certain conditions no longer cause consolidation of VIEs in certain instances. The amendments place more emphasis on variable interests other than fee arrangements and reduce the extent to which related party arrangements cause an entity to be considered a primary beneficiary. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (“ASU 2015-01”). ASU 2015-01 eliminates the presentation and disclosure requirements of extraordinary items because it was unclear when an item should be considered both unusual and infrequent and it was extremely rare

in practice. ASU 2015-01 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this ASU to have an impact on its consolidated financial statements.

In November 2014, the FASB issued ASU 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity (a consensus of the FASB Emerging Issues Task Force) (“ASU 2014-16”). The amendments in ASU 2014-16 do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. Rather, ASU 2014-16 clarifies how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. ASU 2014-16 is effective for existing hybrid financial instruments issued in the form of a share on a modified retrospective basis for fiscal years, and for interim periods within those years, beginning after December 15, 2015. Retrospective application is permitted for all relevant prior periods. The Company does not expect the adoption of this ASU to have an impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The core principle of this ASU is that a company will recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current guidance and will be required to disclose information about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including disclosure of assumptions and estimates where significant judgment has been applied. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended, is effective using either the retrospective or cumulative effect transition method for fiscal years, and for interim periods within those years, beginning after December 15, 2017. Early application is permitted, but not before fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company is currently determining which transition method will be used and evaluating the potential impact of this ASU on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). ASU 2014-08 changes the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Only disposals of components of an entity representing a strategic shift that has, or will have, a major effect on an entity’s operations and financial results should be reported as discontinued operations under ASU 2014-08. Examples include a disposal of a major geographical area, a major line of business, or a major equity method investment. ASU 2014-08 also requires expanded disclosure about discontinued operations and requires disclosure about individually significant dispositions that do not qualify as a discontinued operation. ASU 2014-08 is effective prospectively for fiscal years, and for interim periods within those years, beginning after December 15, 2014. The Company adopted ASU 2014-08 as of January 1, 2015. The adoption of this ASU did not have an impact on the Company’s condensed unaudited consolidated financial statements, but could impact whether future disposals of operations would qualify as discontinued operations.

Note 2 – Earnings Per Share

Basic earnings or loss per share is computed by dividing net income or loss available to MasTec’s common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share is computed by dividing net income or loss available to MasTec’s common shareholders by the number of fully diluted shares, which includes the effect of dilutive potential issuances of common shares as determined using earnings from continuing operations, including the potential issuance of common shares upon the exercise, conversion or vesting of outstanding stock options and unvested restricted shares, as calculated under the treasury stock method, as well as shares associated with the Company’s convertible debt securities, which matured and were converted in 2014. For the three and six month periods ended June 30, 2015, the Company reported a net loss from continuing operations. As a result, dilutive common shares totaling 476,769 and 495,181 for the three and six month periods ended June 30, 2015, respectively, have been excluded from the calculation of diluted net loss per share for the related periods as their effect would have been anti-dilutive. Therefore, diluted net loss per share is the same as basic net loss per share for the three and six month periods ended June 30, 2015.

There were no anti-dilutive common stock equivalents for the three and six month periods ended June 30, 2015, except for those excluded from the calculation of diluted net loss per share as discussed above. For the three and six month periods ended June 30, 2014, there were 304,600 and 182,218 weighted average anti-dilutive common stock equivalents that were not included in calculation of diluted earnings per share because their effect would have been anti-dilutive.

The following table provides details underlying the Company’s earnings per share calculations for the periods indicated (in thousands):



	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2015			2014			2015			2014
				As Restated						As Restated
Net (loss) income attributable to MasTec:

Convertible Notes - Diluted Share Impact

In June 2014, $115 million aggregate principal amount of 4.0% senior convertible notes (the “4.0% Convertible Notes”) matured, at which time the holders elected to convert the notes. Upon conversion, the Company paid $105 million in cash and issued 4.2 million shares of common stock in respect thereof. The 4.0% Convertible Notes were composed of $105 million of 4.0% Convertible Notes issued in 2011 (the “2011 4.0% Notes”) and approximately $10 million of 4.0% Convertible Notes issued in 2009 (the “2009 4.0% Notes”). Additionally, in December 2014, $100 million aggregate principal amount of 4.25% senior convertible notes (the “4.25% Convertible Notes”) matured and were converted, and, upon conversion, the Company paid $97 million in cash and issued 2.4 million shares of common stock in respect of such notes. The 4.25% Convertible Notes were composed of $97 million of 4.25% Convertible Notes issued in 2011 (the “2011 4.25% Notes”) and $3 million of 4.25% Convertible Notes issued in 2009 (the “2009 4.25% Notes”). The 2009 4.0% Notes and the 2009 4.25% Notes are collectively referred to as the “2009 Convertible Notes,” and the 2011 4.0% Notes and the 2011 4.25% Notes are collectively referred to as the “2011 Convertible Notes.”

Until maturity of the 2009 Convertible Notes in 2014, dilutive shares associated with these notes were attributable to the underlying principal amounts and were reflected in the calculation of weighted average diluted earnings per share for the corresponding periods by application of the “if-converted” method. The 2011 Convertible Notes had an optional cash settlement feature, which allowed the Company to settle the principal amount in cash. Until their maturity in 2014, dilutive shares associated with the 2011 Convertible Notes were derived from the premium value of the notes in excess of their principal amounts, as calculated using the treasury stock method. These shares were referred to as the “premium shares.”

The 4.0% Convertible Notes were convertible at $15.76 per share, and the 4.25% Convertible Notes were convertible at $15.48 per share. The calculations underlying the number of premium shares included in the Company’s diluted share count for the periods indicated were as follows (in thousands, except per share amounts):



	2011 4.25% Notes
Premium Share Information:	For the Three Months Ended June 30, 2014		For the Six Months Ended June 30, 2014
Number of conversion shares, principal amount	6,268		6,268
Per share price, actual average	$	37.68	$	37.82
Premium value	$	139,170	$	140,047
Premium shares	3,693		3,703

In addition to the premium shares described above, there were 3.3 million and 3.6 million equivalent premium shares included in the Company's dilutive share calculation for the three and six month periods ended June 30, 2014, respectively, related to the 2011 4.0% Notes, as calculated based on the average price per share of the Company's common stock from the beginning of the period through June 15, 2014, the date of maturity.

Note 3 – Acquisitions

The Company acquired several businesses during 2014, as discussed below and in Note 4 - Acquisitions in the notes to the Company’s audited consolidated financial statements included in its 2014 Form 10-K. As of June 30, 2015, determination of the fair values of the net assets acquired, including the estimated values of contingent earn-out obligations and the estimated useful lives of acquired assets for the WesTower acquisition, as discussed below, were provisional and remained preliminary. Management continues to assess the valuation of these items and any ultimate purchase price adjustments that may result based on the final net assets and net working capital, as prescribed in the purchase agreement. The Company will

revise its preliminary estimates of the fair values of net assets acquired if new information is obtained about the facts and circumstances existing as of the date of acquisition or for purchase price adjustments. Such adjustments may result in the recognition of, or adjust the fair values of, acquired assets and assumed liabilities, and are presented as if the adjustments had been taken into account as of the date of acquisition, which would result in the revision of comparative prior period financial information. All changes that do not qualify as measurement period adjustments are included in current period results.

2014 Acquisitions

WesTower

Effective October 1, 2014, MasTec acquired all of the issued and outstanding equity interests of WesTower Communications Inc. (“WesTower”). WesTower is a telecommunications services firm focusing on construction and maintenance of communications infrastructure related to wireless networks throughout the United States. WesTower, which provides services to a number of major wireless carriers throughout the Eastern, Central and Western United States, is expected to expand the Company’s geographical presence, market penetration and skilled employee base within its existing wireless operations. WesTower is reported within the Company’s Communications segment.

The following table summarizes the preliminary estimated fair values of consideration paid and identifiable assets acquired and liabilities assumed as of the date of acquisition (in millions):



Acquisition consideration:	October 1, 2014
Cash	$	198.0
Identifiable assets acquired and liabilities assumed:
Accounts receivable	$	180.6
Other current assets, including $18.0 million of cash acquired	50.3
Property, equipment and other long-term assets, including deferred tax asset	18.0
Finite-lived intangible assets	42.6
Billings in excess of costs and earnings	(33.3		)
Other current liabilities, including current portion of capital lease obligations	(89.8		)
Long-term liabilities, including capital lease obligations	(21.1		)
Total identifiable net assets	$	147.3
Goodwill	$	50.7
Total net assets acquired, including goodwill	$	198.0

The fair values and weighted average useful lives of WesTower’s acquired finite-lived intangible assets as of the date of acquisition were assigned as follows:



	Fair Value (in millions)		Weighted Average Useful Life (in years)
Finite-lived intangible assets:	Fair Value (in millions)		Weighted Average Useful Life (in years)
Backlog	$	4.7	5
Trade name	1.1		4
Non-compete agreements	0.3		4
Customer relationships	36.5		18
Total acquired finite-lived intangible assets	$	42.6	16

Finite-lived intangible assets are amortized in a manner consistent with the pattern in which the related benefits are expected to be consumed. Goodwill arising from the acquisition represents the estimated value of WesTower’s geographic presence in key high growth markets, its assembled workforce and synergies expected to be achieved from the combined operations of WesTower and MasTec. The goodwill balance is not tax deductible.

In connection with the WesTower acquisition, the Company incurred acquisition integration costs of approximately $7.8 million and $16.6 million for the three and six month periods ended June 30, 2015, respectively, which were included within general and administrative expenses within the condensed unaudited consolidated statements of operations. These acquisition integration costs consisted primarily of employee termination costs, including employee compensation relating to the elimination of certain positions, which were determined to be redundant, and other integration-type costs, including facility consolidation expenses, system migration expenses and training costs. The Company is currently in the process of integrating WesTower and expects to incur additional integration costs in 2015. A liability for such costs is recognized and accrued when incurred. As of June 30, 2015 and December 31, 2014, $1.9 million and $3.5 million, respectively, was included within current liabilities relating to acquisition integration costs. Liabilities assumed in connection with the WesTower acquisition also include the estimated value of certain off-market contracts, which are recognized in revenue over the terms of the related contracts.

Pacer

Effective June 1, 2014, MasTec acquired all of the issued and outstanding equity interests of Pacer Construction Holdings Corporation and its affiliated operating companies (collectively, “Pacer”). Pacer is a western Canadian civil construction services company, headquartered in Calgary, Alberta, Canada. Pacer’s services include infrastructure construction primarily in support of oil and gas production, processing, mining and transportation. Pacer, a leading contractor in the Canadian oil sands market, is expected to enhance MasTec’s ability to develop energy infrastructure in western Canada and take advantage of associated opportunities in North America over the coming years. Pacer is primarily reported within the Company’s Oil and Gas segment.

The following table summarizes the estimated fair values of consideration paid and identifiable assets acquired and liabilities assumed, as adjusted, as of the date of acquisition (in millions):



Acquisition consideration:	June 1, 2014
Cash	$	126.5
Fair value of contingent consideration (earn-out liability)	24.3
Total consideration transferred	$	150.8
Identifiable assets acquired and liabilities assumed:
Current assets, including $3.4 million of cash acquired	$	114.0
Property and equipment	81.2
Pre-qualifications	38.7
Finite-lived intangible assets	19.4
Current liabilities, including current portion of capital lease obligations and long-term debt	(71.8		)
Net equity method investment obligations	(31.0		)
Long-term debt, including capital lease obligations	(69.6		)
Deferred income taxes	(30.5		)
Total identifiable net assets	$	50.4
Goodwill	$	100.4
Total net assets acquired, including goodwill	$	150.8

The values of certain of the assets acquired and liabilities assumed include the proportionate values of Pacer’s undivided interest in an unincorporated contractual joint venture, which is involved in a civil construction project and is accounted for on a proportional basis. Pacer’s undivided interest in this contractual joint venture automatically terminates upon completion of the project. For the three and six month periods ended June 30, 2015, revenue recognized by the Company on behalf of this contractual joint venture totaled $0.9 million and $1.5 million, respectively. As of June 30, 2015 and December 31, 2014, receivables from this contractual joint venture, including acquired receivables, totaled $1.5 million and $1.8 million, respectively. There are performance guarantees associated with this contractual joint venture of a gross amount of Canadian $132.1 million (or approximately $105.7 million and $113.6 million) as of June 30, 2015 and December 31, 2014, respectively, based on the full contract value of the project, for which Pacer is obligated on a joint and several basis with its other joint venture partner. In addition, from time to time, the Company may provide financing to this contractual joint venture. For the six month period ended June 30, 2015, Pacer provided $4.6 million of financing to this contractual joint venture under financing arrangements. As of both June 30, 2015 and December 31, 2014, there were no additional amounts committed by Pacer to this contractual joint venture under such financing arrangements. This project, which is included in the Other segment, was approximately 60% complete as of June 30, 2015.

The equity method investment obligations identified in the table above represent investments in entities that provide civil construction services. As a result of the ongoing review of the acquired net assets of Pacer, the Company determined that the initial fair value assigned to these investments was in excess of their fair value and that it would cease participation in the operations of its equity method investments in 2015 upon completion of the existing projects. Subsequent to the acquisition date, the Company recorded a $49 million reduction to the acquisition date value of Pacer’s equity method investments to reflect their expected fair values as determined based on their expected net cash outflows, including the wind-down of its investments. For the six month periods ended June 30, 2015, revenue recognized by the Company on behalf of these entities totaled $1.5 million, which amount was outstanding as of June 30, 2015. There are performance guarantees associated with these entities of a gross amount of approximately $57.0 million and $61.2 million as of June 30, 2015 and December 31, 2014, respectively, based on the full contract value of certain projects, for which Pacer is obligated on a joint and several basis with the other shareholders. These projects were in varying stages of completion as of June 30, 2015 and are expected to be principally completed in the third quarter of 2015. As of June 30, 2015 and December 31, 2014, excluding the receivership arrangement discussed below, there were approximately $2.8 million and $3.0 million, respectively, of other financial guarantees associated with these investments, for which Pacer is obligated on a joint and several basis, the durations of which correspond to those of the guaranteed transactions or borrowings. The Company believes these obligations and guarantees represent variable interests; however, Pacer does not have the power to control the primary activities of, nor is it the primary beneficiary of, these investments. In addition, from time to time, the Company may provide financing to its equity method investments. During the first half of 2015, Pacer provided $9.3 million of financing to these entities under financing arrangements, $8.6 million of which was reflected within Pacer’s net equity method investment obligations as of the date of acquisition in the table above. As of both June 30, 2015 and December 31, 2014, there were no additional amounts committed by Pacer to these entities under such financing arrangements.

In March 2015, as part of the initiative to wind down operations of an equity method investee, Pacer became the secured creditor thereof by purchasing the outstanding revolving credit facility of this investee for approximately $20.8 million in order to satisfy its obligations pursuant to a financial guarantee to the investee’s lender. This payment is included within Pacer’s net equity method investment obligations as of the date of acquisition in the table above, and as of December 31, 2014, approximately $22.6 million was included within other current liabilities in the Company’s consolidated balance sheet related to this financial guarantee. Subsequent to Pacer’s purchase of the outstanding credit facility, a receivership order was granted to assist with the orderly wind-down of the investee’s operations. As part of the receivership proceedings, Pacer committed to provide the receiver financing of up to approximately $62.4 million as of June 30, 2015, and through June 30, 2015, approximately $28.3 million of this financing commitment had been paid and was recorded within prepaid expenses and other current assets in the condensed unaudited consolidated balance sheet. As of August 12, 2015, Pacer had funded approximately $37.2 million of the total amount committed under the receivership proceedings. The Company anticipates the wind-down period of this receivership will substantially conclude in the third quarter of 2015. Based on operational estimates from the receiver, the Company believes Pacer will be repaid the amounts advanced under the receivership financing commitment within the next twelve months, with the substantial portion expected to be collected in the latter part of 2015.

Subsequent to the acquisition date, in connection with the ongoing review of the acquired net working capital and acquired net assets of Pacer, the Company recorded an $8.4 million increase in property and equipment, a $5.6 million increase in certain current liabilities and a $1.2 million increase in long-term deferred tax liabilities. These adjustments, along with the adjustments to the equity method investment obligations discussed above, as well as other immaterial adjustments, net, in the acquisition date values of certain current assets and intangible assets, resulted in a $47.5 million increase in the acquisition date value of goodwill associated with the Pacer acquisition.

The fair values and weighted average useful lives of Pacer’s acquired finite-lived intangible assets, as adjusted, as of the date of acquisition were assigned as follows:



	Fair Value (in millions)		Weighted Average Useful Life (in years)
Finite-lived intangible assets:	Fair Value (in millions)		Weighted Average Useful Life (in years)
Backlog	$	6.1	3
Non-compete agreements	2.3		9
Customer relationships	11.0		8
Total acquired finite-lived intangible assets	$	19.4	6

Finite-lived intangible assets are amortized in a manner consistent with the pattern in which the related benefits are expected to be consumed. The intangible asset related to Pacer’s pre-qualifications with selected customer companies has been assigned an indefinite life as the pre-qualifications are not expected to expire or diminish in value, and the companies to which they relate have extremely long operating histories. Goodwill arising from the acquisition represents the estimated value of Pacer’s geographic presence in key high-growth Canadian markets, its assembled workforce, its management team’s industry-specific project management expertise and synergies expected to be achieved from the combined operations of Pacer and MasTec. The goodwill balance is not tax deductible.

The contingent consideration included in the table above equals 25% of the excess, if any, of Pacer’s earnings from continuing operations before interest, taxes, depreciation and amortization (“EBITDA”) above certain thresholds for a five-year period, as set forth in the purchase agreement, and is payable annually in Canadian dollars. The fair value of the earn-out liability was estimated using an income approach and incorporates significant inputs not observable in the market. Key assumptions in the estimated valuation include the discount rate and probability-weighted EBITDA projections. Significant changes in any of these assumptions could result in a significantly higher or lower potential earn-out liability. The range of potential undiscounted payments that MasTec could be required to make under the earn-out arrangement is estimated to be between Canadian $0 and $71 million, or approximately $0 and $57 million as of June 30, 2015; however, there is no maximum earn-out payment amount. As is customary for purchase agreements in the industry, the earn-out agreement contains certain right of offset provisions, under which the Company may, under certain circumstances, offset against the earn-out liability working capital adjustments, indemnification claims and similar items owed from the former owners of the entity.

Other 2014 Acquisitions

Effective April 1, 2014, MasTec acquired 100% of a telecommunications services firm, specializing in the installation of in-home security systems, for an aggregate purchase price composed of approximately $16.3 million in cash, as adjusted for the final net working capital, and a five year earn-out, valued at $0.6 million as of June 30, 2015. Additionally, effective January 1, 2014, MasTec acquired 100% of a telecommunications services firm, specializing in the engineering, installation, furnishing and integration of telecommunications equipment, for an aggregate purchase price composed of approximately $23.8 million in cash and a five year earn-out, valued at $8.7 million as of June 30, 2015. These companies are included in MasTec’s Communications segment.

Unaudited Supplemental Pro Forma Information

The following unaudited supplemental pro forma financial information includes the results of operations of each of the companies acquired in 2014 and is presented as if each acquired company had been consolidated as of the beginning of the year immediately preceding the year in which the company was acquired. The unaudited supplemental pro forma financial information has been provided for illustrative purposes only and does not purport to be indicative of the actual results that would have been achieved by the combined companies for the periods presented, or of the results that may be achieved by the combined companies in the future. Future results may vary significantly from the results reflected in the following unaudited supplemental pro forma financial information because of future events and transactions, as well as other factors, many of which are beyond MasTec’s control.

The unaudited supplemental pro forma financial information presented below has been prepared by adjusting the historical results of MasTec to include the historical results of the acquired businesses described above and was then adjusted (i) to remove one-time acquisition costs, including certain acquisition integration costs; (ii) to increase amortization expense resulting from the incremental intangible assets acquired; (iii) to increase interest expense as a result of the cash consideration paid; (iv) to remove integration-related employee redundancy costs; and (v) to reduce interest expense from debt repaid upon acquisition of the respective businesses. The unaudited supplemental pro forma financial information does not include adjustments to reflect the impact of other cost savings or synergies that may result from these acquisitions.

Note 5 – Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts and notes receivable, cash collateral deposited with insurance carriers, life insurance assets, cost and equity method investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration, certain intangible assets and liabilities, including off-market contracts, and debt obligations.

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: (i) Level 1 - quoted market prices in active markets for identical assets or liabilities; (ii) Level 2 - observable market based inputs or other observable inputs; and (iii) Level 3 - significant unobservable inputs that cannot be corroborated by observable market data, which are generally determined using valuation models incorporating management estimates of market participant assumptions. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.

Fair values of financial instruments are estimated using public market prices, quotes from financial institutions and other available information. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and other current liabilities approximate their fair values. Management believes the carrying values of notes receivable, cash collateral deposited with insurance carriers, deferred compensation plan assets and liabilities and outstanding balances on its credit facilities approximate their fair values. Cost and equity method investments are initially recorded at their cost basis.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of June 30, 2015 and December 31, 2014, financial instruments required to be measured at fair value on a recurring basis consisted primarily of acquisition-related contingent consideration liabilities, which represent the estimated fair value of additional future earn-outs payable for acquisitions of businesses that closed after January 1, 2009 (“ASC 805 contingent consideration”), in accordance with U.S. GAAP. The fair value of ASC 805 contingent consideration is based on management estimates and entity-specific assumptions, which are Level 3 inputs, and is evaluated on an ongoing basis. As of June 30, 2015 and December 31, 2014, the fair value of the Company’s ASC 805 contingent consideration totaled $106.7 million and $146.1 million, respectively.

Additions to ASC 805 contingent consideration from new business combinations for the three and six month periods ended June 30, 2015 and 2014 were $0.0 million, $0.0 million, $24.9 million and $33.6 million, respectively. In connection with ASC 805 contingent consideration for the three and six month periods ended June 30, 2015 and 2014 the Company paid approximately $32.2 million, $32.2 million, $47.0 million and $47.0 million, respectively. In the second quarter of 2015, the Company recognized a $3.6 million net reduction in ASC 805 contingent consideration, a portion of which related to an acquired business in our Electrical Transmission segment, which was recorded within other income, net, in the condensed unaudited consolidated statements of operations. Foreign currency translation gains and/or losses associated with ASC 805 contingent consideration are included in other comprehensive income. For the three month period ended June 30, 2015, foreign currency translation losses associated with ASC 805 contingent consideration totaled $1.0 million, and for the six month period ended June 30, 2015, foreign currency translation gains totaled $3.6 million. Foreign currency translation losses associated with ASC 805 contingent consideration totaled $1.7 million and $0.4 million for the three and six month periods ended June 30, 2014, respectively.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Assets and liabilities recognized or disclosed at fair value on a non-recurring basis, for which remeasurement occurs in the event of an impairment or other measurement event, if applicable, include items such as cost and equity method investments, life insurance assets, long-lived assets, goodwill, other intangible assets and liabilities, including off-market contracts and debt. As of both June 30, 2015 and December 31, 2014, the carrying amount of the Company’s 4.875% senior notes due 2023 (the “4.875% Senior Notes”) totaled $400 million. As of June 30, 2015 and December 31, 2014, the estimated fair value of the Company’s 4.875% Senior Notes, based on quoted market prices in active markets, a Level 1 input, totaled $364.0 million and $375.0 million, respectively.

Cost and Equity Method Investments. The aggregate carrying value of the Company’s cost and equity method investment assets, including long-term receivables from investees and contractual joint ventures, totaled approximately $21.9 million and $17.7 million as of June 30, 2015 and December 31, 2014, respectively. In June 2015, MasTec invested $6 million, and committed to future equity contributions and/or loan guarantees of up to an additional $78 million, for a 33% equity interest in two joint ventures. The joint ventures were formed to design, build, own and operate a header system and two pipelines that will transport natural gas. A subsidiary of MasTec will construct the pipelines, with construction expected to commence in late 2015 or early 2016. Each pipeline is planned to interconnect at the United States/Mexico border with pipelines currently under development and construction in Mexico.

In addition, as of June 30, 2015 and December 31, 2014, the Company had approximately $1.3 million and $32.4 million of other current liabilities, respectively, relating to its equity method investments, as discussed in Note 3 - Acquisitions. The fair values of the Company’s cost and equity method investments are not readily available. The Company is not aware of events or changes in circumstances that would have a significant adverse effect on the carrying values of its cost and/or equity method investments as of June 30, 2015 or December 31, 2014.

Note 6 - Accounts Receivable, Net of Allowance

The following table provides details of accounts receivable, net of allowance, as of the dates indicated (in millions):

Retainage, which has been billed, but is not due until the Company’s completion of performance and acceptance by customers, is generally expected to be collected within one year. Receivables expected to be collected beyond one year are recorded within other long-term assets. Provisions for doubtful accounts for the three month periods ended June 30, 2015 and 2014 totaled $0.2 million and $0.3 million, respectively, and for the six month periods ended June 30, 2015 and 2014 totaled $0.7 million and $0.8 million, respectively. The provision for doubtful accounts for the three and six month periods ended June 30, 2014 included a reversal of $0.5 million to eliminate a reserve that was not required and should have been reversed in a prior year. Based on materiality considerations, this item was recognized in 2014.

During 2014, the Company entered into a non-recourse financing arrangement, under which certain receivables are purchased by the customer’s bank for a nominal fee. This arrangement improved the collection cycle time of the related receivables, the effect of which amounted to cash collections of approximately $28 million in the second quarter of 2015. Cash collected from this arrangement is reflected within cash provided by operating activities. The discount charge, which was immaterial for the three and six-month periods ended June 30, 2015, is included within interest expense in the consolidated statements of operations.

Senior Secured Credit Facility

The Company has a senior secured credit facility, referred to as the Credit Facility. Under the Credit Facility, aggregate borrowing commitments total $1.25 billion, composed of $1.0 billion of revolving commitments and a term loan in the aggregate principal amount of $250 million (the “Term Loan”). The Credit Facility provides the ability to borrow in either Mexican pesos or Canadian dollars, up to an aggregate equivalent amount of $200 million. Revolving commitments under the Credit Facility mature on October 29, 2018, and the Term Loan matures on November 21, 2019. The Term Loan is subject to amortization in quarterly principal installments of $3.1 million, subject to reduction as a result of the application of certain prepayments in accordance with the terms of the Credit Facility, commencing as of the quarter ending March 31, 2016 and continuing for each fiscal quarter thereafter. The maximum amount available for letters of credit under the Credit Facility is $450 million, of which up to $100 million can be denominated in either Mexican pesos or Canadian dollars. The Credit Facility also provides for swing line loans of up to $75 million. Under the Credit Facility, the Company has the option to increase revolving commitments and/or establish additional term loan tranches in an aggregate amount of $250 million. Borrowings under the Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including equity, joint venture and other investments, the repurchase or prepayment of indebtedness and share repurchases under authorized share repurchase programs. Deferred financing costs associated with the Credit Facility, including the Term Loan, totaled $6.2 million and $6.9 million, net of accumulated amortization as of June 30, 2015 and December 31, 2014, respectively.

As of June 30, 2015 and December 31, 2014, outstanding revolving loans under the Credit Facility accrued interest at weighted average rates of approximately 2.52% and 2.18% per annum, respectively, and the Term Loan accrued interest at a rate of 1.94% and 1.92% as of June 30, 2015 and December 31, 2014, respectively.

Outstanding letters of credit mature at various dates and most have automatic renewal provisions, subject to prior notice of cancellation. As of June 30, 2015 and December 31, 2014, borrowing capacity of $468.2 million and $563.7 million, respectively, was available for revolving loans, or up to $274.2 million and $296.4 million, respectively, for new letters of credit. The unused facility fee was 0.35% as of both June 30, 2015 and December 31, 2014. The Credit Facility is guaranteed by certain subsidiaries of the Company (the “Guarantor Subsidiaries”), and the obligations under the Credit Facility are secured by substantially all of the Company’s and the Guarantor Subsidiaries’ respective assets, subject to certain exceptions.

The Credit Facility is subject to certain provisions and covenants, as more fully described in Note 10 - Debt in the notes to the audited consolidated financial statements included in the 2014 Form 10-K, including a requirement to deliver periodic financial statements to the bank group under the Credit Facility. In connection with the delayed filing of the 2014 Form 10-K and the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2015 (the “First Quarter 2015 Form 10-Q”), the Company received consents from its bank group, which extended the delivery date requirements of the Company’s audited consolidated financial statements for the year ended December 31, 2014 and the condensed unaudited consolidated financial statements for the quarter ended March 31, 2015. With the filing of its First Quarter 2015 Form 10-Q, the Company met the reporting requirements with respect to its Credit Facility.

Other Credit Facilities. The Company has other credit facilities to support the working capital requirements of its foreign operations. Borrowings under these credit facilities, which have varying dates of maturity and are generally renewed on an annual basis, are primarily denominated in Canadian dollars. Maximum borrowing capacity totaled Canadian $45.0 million as of both June 30, 2015 and December 31, 2014, or approximately $36.0 million and $38.7 million, respectively. Outstanding borrowings totaled approximately $26.0 million and $1.2 million as of June 30, 2015 and December 31, 2014, respectively. Outstanding borrowings accrued interest at a weighted average rate of 3.9% and 4.0% as of June 30, 2015 and December 31, 2014, respectively. Outstanding borrowings that are not renewed are repaid with borrowings under the Credit Facility.

Certain of MasTec’s subsidiaries, including certain subsidiaries in Canada, contribute amounts to multi-employer pension and other multi-employer benefit plans and trusts, which are recorded as a component of employee wages and salaries within costs of revenue, excluding depreciation and amortization. Contributions are generally based on fixed amounts per hour per employee for employees covered under these plans. Multi-employer plan contribution rates are determined annually and assessed on a “pay-as-you-go” basis based on union employee payrolls. Union payrolls cannot be determined for future periods because the number of union employees employed at any given time, and the plans in which they may participate, vary depending upon the location and number of ongoing projects at a given time and the need for union resources in connection with those projects. Total contributions to multi-employer plans, and the related number of employees covered by these plans, including with respect to the Company’s Canadian operations, for the periods indicated were as follows:



	Multi-Employer Plans
	Covered Employees				Contributions (in millions)
For the Three Months Ended June 30:	Low		High		Pension		Post-Retirement Benefit		Total
2015	1,124		2,463		$	9.3	$	2.2	$	11.5
2014	$	1,308	$	2,167	$	8.0	$	0.8	$	8.8

2014	1,098		2,167		$	15.8	$	1.3	$	17.1

Note 12 – Equity

Share Activity

During the fourth quarter of 2014, the Company’s Board of Directors authorized a $100 million share repurchase program (the “2014 Share Repurchase Program”), which provided the Company the ability to repurchase shares of its common stock from time to time in open market transactions or in privately-negotiated transactions, in accordance with applicable securities laws. Repurchased shares are held in the Company’s treasury. As of December 31, 2014, no shares of the Company’s common stock had been repurchased under this program. During the six months ended June 30, 2015, the Company repurchased 5.2 million shares of its common stock for an aggregate purchase price of $100 million, which completed the 2014 Share Repurchase Program.



Share Activity (in thousands):	Common Shares Outstanding		Treasury Shares
Balance as of December 31, 2014	84,739		2,876
Shares issued:
Stock option exercises	64
Restricted share awards	188
Common stock repurchases	(5,218	)	5,218
Other, net	67

Accumulated Other Comprehensive Loss

Accumulated other comprehensive losses totaled $52.7 million and $34.0 million as of June 30, 2015 and December 31, 2014, respectively. For the three month period ended June 30, 2015, unrealized foreign currency translation gains totaled $3.3 million, and for the six month period ended June 30, 2015, unrealized foreign currency translation losses totaled $18.7 million. For the three and six month periods ended June 30, 2014, unrealized foreign currency translation gains totaled $7.7 million and $2.3 million, respectively. Unrealized foreign currency gains and losses relate primarily to fluctuations in foreign currency exchange rates of the Company’s foreign subsidiaries with a functional currency other than the U.S. dollar. Foreign currency activity, which has grown in recent years due to acquisitions, is related primarily to the Company’s Canadian operations.

Note 13 - Income Taxes

In determining the quarterly provision for income taxes, management uses an estimated annual effective tax rate based on forecasted annual pre-tax income, permanent tax differences, statutory tax rates and tax planning opportunities in the various jurisdictions in which the Company operates. The effect of significant discrete items is separately recognized in the quarter(s) in which they occur. In the second quarter of 2015, the Company incurred $2.8 million of income tax expense in connection with the non-recurring cumulative revaluation of certain deferred tax liabilities pursuant to an Alberta provincial income tax law that was enacted as of June 29, 2015. As of June 30, 2015, the Company had $28.1 million of current deferred tax assets, net, and $189.8 million of long-term deferred tax liabilities, net. As of December 31, 2014, current deferred tax assets, net, totaled $31.7 million and long-term deferred tax liabilities, net, totaled $203.5 million.

Note 14 - Segments and Related Information

Segment Discussion

MasTec manages its continuing operations under five operating segments, which represent MasTec’s five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Power Generation and Industrial and (5) Other. This structure is generally focused on broad end-user markets for MasTec’s labor-based construction services. All five reportable segments derive their revenue from the engineering, installation and maintenance of infrastructure, primarily in North America. In the first quarter of 2015, the Company reevaluated the activities of a non-controlled Canadian joint venture associated with a 2014 acquisition. Accordingly, segment information for prior periods has been adjusted retrospectively to conform to the current period presentation. The reclassified amounts were not material in the periods previously presented. See Note 16 - Segments and Related Information in the Company’s 2014 Form 10-K for additional details.

The Communications segment performs engineering, construction and maintenance of communications infrastructure primarily related to wireless and wireline/fiber communications and install-to-the-home customers, and, to a lesser extent, infrastructure for electrical utilities. MasTec performs engineering, construction and maintenance services on oil and natural gas pipelines and processing facilities for the energy and utilities industries through its Oil and Gas segment. The Electrical Transmission segment primarily serves the energy and utility industries through the engineering, construction and maintenance of electrical transmission lines and substations. The Power Generation and Industrial segment primarily serves energy, utility and other end-markets through the installation and construction of conventional and renewable power facilities, related electrical transmission infrastructure, ethanol facilities and various types of industrial infrastructure. The Other segment primarily includes a proportionately consolidated joint venture and other small business units that perform construction services for a variety of end-markets in Canada, Mexico and elsewhere internationally.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is the measure of profitability used by management to manage its segments and, accordingly, in its segment reporting. As appropriate, the Company supplements the reporting of consolidated financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including EBITDA. The Company believes these non-U.S. GAAP measures provide meaningful information and help investors in understanding the Company’s financial results and in assessing its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and versus that of its peers, because it excludes certain items that may not be indicative of the Company’s reportable segment results, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is calculated in a manner consistent with consolidated EBITDA.

For the three month period ended June 30, 2015, Communications segment EBITDA included $7.8 million of acquisition integration costs resulting from the WesTower acquisition and Corporate segment EBITDA included $6.7 million of Audit Committee independent investigation related costs. For the six month period ended June 30, 2015, Communications segment EBITDA included $16.6 million of acquisition integration costs resulting from the WesTower acquisition, Corporate segment EBITDA included $9.7 million of Audit Committee independent investigation related costs, Power Generation and Industrial segment EBITDA included $16.0 million of previously disclosed first quarter losses on a Canadian wind project and Other segment EBITDA included $5.5 million of previously disclosed first quarter losses on a non-controlled proportionately consolidated Canadian joint venture.

Summarized financial information for MasTec’s reportable segments is presented and reconciled to consolidated financial information for total MasTec in the following tables (in millions):

The majority of the Company’s foreign operations during the three and six month periods ended June 30, 2015 and 2014 were in the Company’s Oil and Gas segment. Long-lived assets held in the United States included property and equipment, net, of $498.1 million and $494.1 million as of June 30, 2015 and December 31, 2014, respectively. Long-lived assets held in foreign countries, primarily in Canada, included property and equipment, net, of $116.7 million and $129.0 million as of June 30, 2015 and December 31, 2014, respectively. Intangible assets and goodwill, net, of approximately $1.1 billion as of both June 30, 2015 and December 31, 2014 related to the Company’s U.S. operations. Intangible assets and goodwill, net, of approximately $207.7 million and $227.7 million as of June 30, 2015 and December 31, 2014, respectively, related to businesses in foreign countries, primarily in Canada. Foreign customers accounted for approximately 22% and 20% of the Company’s consolidated net accounts receivable position, which represents accounts receivable, net, less billings in excess of costs and earnings, as of June 30, 2015 and December 31, 2014, respectively.

(d)	The Company’s relationship with Enbridge, Inc. is based upon various construction contracts for natural gas pipelines. Revenue from Enbridge, Inc. is included in the Oil and Gas segment.

Note 15 - Commitments and Contingencies

In addition to the matters discussed below, MasTec is subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of its business. MasTec cannot provide assurance that it will be successful in recovering all or any of the potential damages it has claimed or in defending claims against it. The outcome of such cases, claims and disputes, including those set forth below, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.

PPL. In October 2012, PPL Electric Utilities Corporation (“PPL”) and T&D Power, Inc., a MasTec, Inc. subsidiary (“T&D”), entered into a $206 million overhead transmission line construction contract (the “Contract”), pursuant to which T&D agreed to construct an approximately 100 mile transmission line in Pennsylvania. In September 2013, PPL issued a notice terminating the Contract for convenience. T&D then submitted termination invoices to recover certain pre-termination costs, overhead and profit, as well as termination-related demobilization costs, along with the applicable overhead and profit. PPL disputes these invoices. As a result of the dispute, T&D sued PPL in December 2013 in federal court in the Eastern District of Pennsylvania, and is pursuing claims in excess of $40 million for breach of contract, including PPL’s breach of its implied duty of good faith and fair dealing. Although T&D has attempted to resolve the dispute with PPL through negotiation, mediation in 2014 was unsuccessful. Discovery has been completed. In July 2015, PPL filed a motion for partial summary judgment, and T&D filed a response. A trial is scheduled for October 2015.

SunLight Entities. In 2011, Power Partners MasTec, LLC., a MasTec, Inc. subsidiary (“Power Partners”), entered into engineering, procurement, and construction agreements (the “EPC Agreements”) with special purpose entities, SunLight General Somerset Solar, LLC, SunLight General Morris Solar, LLC and SunLight General Sussex Solar, LLC (collectively, the “SunLight Entities”), respectively, to perform design and construction services for three public solar projects in New Jersey located in Somerset, Morris and Sussex Counties (the “Projects”). Power Partners and the SunLight Entities engaged in three separate arbitration proceedings against each other to address various disputes that existed between the parties regarding the Projects. In August 2014, the arbitration panel rendered awards in Power Partners’ favor in the aggregate amount of approximately $68 million, including fees and expenses. Power Partners also filed a lawsuit in June 2013 in federal court in New Jersey against the Somerset and Morris Authorities (the “Authorities”) and the principals of the SunLight Entities with claims exceeding $60 million as part of its efforts to seek payment of amounts that were also the subject of the arbitration proceedings.

In March 2015, the Authorities, the SunLight Entities and principals and Power Partners entered into separate settlement agreements. As part of the settlement, Power Partners has received amounts that are substantially equal to the previously recorded amounts, and all of the parties executed mutual releases.

Wrigley v. MasTec, Inc. On May 7, 2015, a putative class action lawsuit (the “Lawsuit”), Wrigley v. MasTec, Inc., et. al. (Case No. 1:15-cv-21740) was filed in the United States District Court, Southern District of Florida, naming the Company, the Company’s Chief Executive Officer, José R. Mas, and the Company’s Chief Financial Officer, George L. Pita, as defendants. The Lawsuit has been purportedly brought by a shareholder, both individually and on behalf of a putative class of shareholders, alleging violations of the federal securities laws arising from alleged false or misleading statements contained in, or alleged material omissions from, certain of the Company’s filings with the SEC and other statements, in each case with respect to accounting matters that are the subject of the independent internal investigation being conducted by the Audit Committee of the Company’s Board of Directors. The Lawsuit seeks damages, prejudgment and post-judgment interest, as well as reasonable attorneys’ fees, expert fees and other costs. The Company believes that the Lawsuit is without merit and intends to vigorously defend against it; however, there can be no assurance that the Company will be successful in its defense.

Other Commitments and Contingencies

Regulatory Matters. The Company has self-reported to the staff of the SEC (“the Staff”) regarding the previously disclosed Audit Committee’s independent investigation and is cooperating with the Staff’s requests for additional information regarding the investigation. The Company intends to continue full cooperation with the SEC.

Leases. In the ordinary course of business, the Company enters into non-cancelable operating leases for certain of its facility, vehicle and equipment needs, including related party leases. See Note 9 - Lease Obligations.

Letters of Credit. In the ordinary course of business, the Company is required to post letters of credit for its insurance carriers, surety bond providers and in support of performance under certain contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit under certain conditions. If this were to occur, the Company would be required to reimburse the issuer of the letter of credit, which, depending upon the circumstances, could result in a charge to earnings. As of June 30, 2015 and December 31, 2014, there were $175.8 million and $153.6 million, respectively, of letters of credit issued under the Company’s Credit Facility. The Company is not aware of material claims relating to outstanding letters of credit as of June 30, 2015 or December 31, 2014.

Performance and Payment Bonds. In the ordinary course of business, MasTec is required by certain customers to provide performance and payment bonds for some of the Company’s contractual commitments related to projects in process. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay subcontractors and vendors. If the Company fails to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of June 30, 2015, the estimated cost to complete projects secured by the Company’s $653.1 million in performance and payment bonds was $24.4 million. As of December 31, 2014, the estimated cost to complete projects secured by the Company’s $748.3 million in performance and payment bonds was $60.1 million. These amounts do not include performance and payment bonds associated with the Company’s equity method investments and contractual joint venture, which are separately disclosed in Note 3 - Acquisitions.

Investments in Affiliates and Other Entities. The Company holds an undivided interest in a contractual joint venture with a third party for the purpose of providing infrastructure construction services under certain customer contracts. Losses incurred by the joint venture are generally shared proportionally by the joint venture members, with members of the joint venture jointly and severally liable for all of the obligations of the joint venture. The joint venture agreement provides that each joint venture partner indemnify the other party for any liabilities incurred by such joint venture in excess of its ratable portion of such liabilities. Thus, it is possible that the Company could be required to pay or perform obligations in excess of its share if the other joint venture partner fails or refuses to pay or perform its share of the obligations. As of June 30, 2015, the Company was not aware of circumstances that would reasonably lead to future claims against it for material amounts. From time to time, the Company may provide financing to its unconsolidated affiliates, including its equity method investees and/or contractual joint venture. During the first half of 2015, excluding receivership commitments related to an equity method investee being wound down, the Company paid approximately $13.9 million under such financing arrangements, and, through August 12, 2015, had paid an additional $2.4 million, none of which additional amount was committed as of June 30, 2015. As of December 31, 2014, there were no amounts committed under such financing arrangements. See Note 3 - Acquisitions and Note 5 - Fair Value of Financial Instruments for discussion pertaining to certain of the Company’s cost and equity method investments and other investment arrangements.

Self-Insurance. MasTec maintains insurance policies for workers’ compensation, general liability and automobile liability, which are subject to per claim deductibles. The Company also maintains excess umbrella coverage. As of June 30, 2015 and December 31, 2014, MasTec’s liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $70.8 million and $70.3 million, respectively, of which $41.6 million and $39.6 million, respectively, were reflected within other long-term liabilities in the consolidated balance sheets. MasTec also maintains an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses. MasTec’s liability for employee group medical claims as of June 30, 2015 and December 31, 2014 totaled $3.7 million and $4.4 million, respectively.

The Company is required to post letters of credit and provide cash collateral to certain of its insurance carriers and to provide surety bonds in certain states. Insurance-related letters of credit for the Company’s workers’ compensation, general liability and automobile liability policies amounted to $75.0 million as of both June 30, 2015 and December 31, 2014. In addition, cash collateral deposited with insurance carriers, which is included within other long-term assets in the consolidated balance sheets, amounted to $1.4 million and $1.2 million for these policies as of June 30, 2015 and December 31, 2014, respectively. Outstanding surety bonds related to workers’ compensation self-insurance programs amounted to $13.0 million as of both June 30, 2015 and December 31, 2014.

Employment Agreements. The Company has employment agreements with certain executives and other employees, which provide for compensation and certain other benefits and for severance payments under certain circumstances. Certain employment agreements also contain clauses that become effective upon a change in control of the Company. Upon the occurrence of any of the defined events in the various employment agreements, the Company would be obligated to pay certain amounts to the relevant employees, which vary with the level of the employees’ respective responsibility.

Collective Bargaining Agreements and Multi-Employer Plans. Certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees. These agreements require the subsidiaries party to the agreements to pay specified wages, provide certain benefits to their union employees and contribute certain amounts to multi-employer pension plans and employee benefit trusts. The collective bargaining agreements expire at various times and have typically been renegotiated and renewed on terms similar to the ones contained in the expiring agreements.

The Employee Retirement Income Security Act of 1974, as amended by the Multi-Employer Pension Plan Amendments Act of 1980 (collectively, “ERISA”), which governs U.S.-registered multi-employer pension plans, subjects employers to substantial liabilities in the event of the employer’s complete or partial withdrawal from, or upon termination of, such plans. Under current law pertaining to employers who are contributors to U.S.-registered multi-employer defined benefit plans, a plan’s termination, an employer’s voluntary withdrawal from, or the mass withdrawal of contributing employers from, an underfunded multi-employer defined benefit plan requires participating employers to make payments to the plan for their proportionate share of the multi-employer plan’s unfunded vested liabilities. These liabilities include an allocable share of the unfunded vested benefits of the plan for all plan participants, not only for benefits payable to participants of the contributing employer. As a result, participating employers may bear a higher proportion of liability for unfunded vested benefits if the other participating employers cease to contribute to, or withdraw from, the plan. The allocable portion of liability to participating employers could be more disproportionate if employers that have withdrawn from the plan are insolvent, or if they otherwise fail to pay their proportionate share of the withdrawal liability. The Company currently contributes, and in the past has contributed to, plans that are underfunded, and, therefore, could have potential liability associated with a voluntary or involuntary withdrawal from, or termination of, these plans. While the Company does not currently have plans to withdraw from, and is not aware of related liabilities associated with these plans, there can be no assurance that the Company will not be assessed liabilities in the future. The Pension Protection Act of 2006 (“PPA”) added funding rules to U.S.-registered plans classified as “endangered,” “seriously endangered,” or “critical” status. The PPA requires that underfunded pension plans improve their funding ratios within prescribed intervals based on their level of underfunding. If a plan is in critical status, benefit reductions may apply and/or participating employers could be required to make additional contributions. In addition, if a multi-employer defined benefit plan fails to satisfy certain minimum funding requirements, the Internal Revenue Service (“IRS”) may impose on the employers contributing to such plan a non-deductible excise tax of 5% of the amount of the accumulated funding deficiency.

Based upon the information available to the Company from plan administrators as of June 30, 2015, several of the multi-employer pension plans in which it participates are underfunded and, as a result, the Company could be required to increase its contributions. Some of the Company’s subsidiaries have also been notified that certain plans to which they contribute are in “critical” status and require additional contributions in the form of a surcharge on future benefit contributions required for future work performed by union employees covered by these plans. The amount of additional funds the Company may be obligated to contribute in the future cannot be estimated, as these amounts are based on future levels of work of the union employees covered by the plans.

In November 2014, the Company, along with other members of the Pipe Line Contractors Association (“PLCA”), voluntarily terminated its participation in several defined benefit multi-employer pension plans. No withdrawal liability was assessed as of the date of the Company’s termination of participation in these plans. There can be no assurance, however, that these plans, which were in critical status as of the date the Company terminated its participation, will not assess penalties in the future. Additionally, in November 2011, the Company, along with other members of the PLCA, voluntarily withdrew from the Central States Southeast and Southwest Areas Pension Fund (“Central States”), a defined benefit multi-employer pension plan that is in critical status. In connection with this withdrawal, a $6.4 million withdrawal liability was established based on an estimate provided by the Central States administrator as of the date of withdrawal. The Company began paying installments towards this withdrawal liability in 2013, of which $3.6 million and $4.2 million was outstanding as of June 30, 2015 and December 31, 2014, respectively. The Company withdrew from Central States in order to mitigate its liability in connection with the plan; however, Central States has asserted that the PLCA members did not effectively withdraw in 2011 and are, therefore, responsible for a withdrawal liability that includes 2011 contribution amounts. By letter dated March 14, 2013, Central States demanded $11 million in withdrawal liability from the Company, which included 2011 contribution amounts. The Company is vigorously opposing this demand because it believes that it legally and effectively withdrew from Central States in November 2011. If Central States were to prevail in its assertion that the Company withdrew after that date, then the initial amount of the Company’s withdrawal liability would increase to approximately $11 million. If Central States or other plans from which the Company has withdrawn were to undergo a mass withdrawal, as defined by ERISA and the Pension Benefit Guaranty Corporation, within the three-year period commencing with the beginning of the calendar year during which the Company effectively withdrew from the plan, there could be additional liability. Given the uncertain nature of the outcome of these factors, the ultimate withdrawal liability can only be estimated.

Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of June 30, 2015 and December 31, 2014, the Company was not aware of material asserted or unasserted claims in connection with these indemnity obligations.

Other Guarantees. In the ordinary course of its business, from time to time, MasTec guarantees the obligations of its subsidiaries, including obligations under certain contracts with customers, certain lease obligations and in some states, obligations in connection with obtaining contractors’ licenses. MasTec has also issued performance and other guarantees in connection with its undivided interest in a contractual joint venture and certain of its equity investees. See Note 3 - Acquisitions. MasTec also generally warrants the work it performs for a one to two year period following substantial completion of a project. MasTec has not historically accrued reserves for potential warranty claims as they have been immaterial.

Concentrations of Risk. The Company had approximately 430 customers for the six month period ended June 30, 2015. As of June 30, 2015, and December 31, 2014, one customer accounted for approximately 7% and 18%, respectively, of the Company’s consolidated net accounts receivable position, which represents accounts receivable, net, less billings in excess of costs and earnings. In addition, the Company derived 58% and 70% of revenues from its top ten customers for the three month periods ended June 30, 2015 and 2014, respectively, and derived 57% and 69% of revenues, respectively, from its top ten customers for the six month periods ended June 30, 2015 and 2014. Taking into consideration the July 2015 acquisition of DIRECTV^® by AT&T, a single customer would have represented 9% and 19% of the Company’s consolidated net accounts receivable

position as of June 30, 2015 and December 31, 2014, respectively, and revenue derived from the Company’s ten largest customers would have totaled 60% and 71% for three month periods ended June 30, 2015 and 2014, respectively, and would have totaled 59% and 70%, respectively, for the six month periods ended June 30, 2015 and 2014. See Note 14 - Segments and Related Information for significant customer revenue concentration information.

We offer our services primarily under the MasTec service mark and, as of June 30, 2015, we had approximately 17,100 employees and 470 locations. We have been consistently ranked among the top specialty contractors by Engineering News-Record for the past several years.

We provide our services to a diversified base of customers. We often provide services under master service and other service agreements, which are generally multi-year agreements. The remainder of our work is generated pursuant to contracts for specific projects or jobs that require the

construction or installation of an entire infrastructure system or specified units within an infrastructure system. Revenue from non-recurring, project specific work may experience greater variability than master service agreement work due to the need to replace the revenue as projects are completed. If we are not able to replace work from completed projects with new project work, we may not be able to maintain our current revenue levels or our current level of capacity and resource utilization. We actively review our backlog of project work and take appropriate action to minimize such exposure.

We manage our continuing operations under five operating segments, which represent our five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Power Generation and Industrial and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services. Throughout this report, segment information for prior periods has been updated to conform to the current period presentation. See Note 16 - Segments and Related Information in the Company’s 2014 Form 10-K for additional details.

The Communications segment performs engineering, construction and maintenance of communications infrastructure primarily related to wireless and wireline/fiber communications and install-to-the-home customers. We perform engineering, construction and maintenance services on oil and natural gas pipelines and processing facilities for the energy and utilities industries through the Oil and Gas segment. The Electrical Transmission segment primarily serves the energy and utility industries through the engineering, construction and maintenance of electrical transmission lines and substations. The Power Generation and Industrial segment primarily serves energy, utility and other end-markets through the installation and construction of conventional and renewable power facilities, related electrical transmission infrastructure, ethanol facilities and various types of industrial infrastructure. The Other segment primarily includes a proportionately consolidated joint venture and other small business units that perform construction services for a variety of end-markets in Canada, Mexico and elsewhere internationally.

See Note 14 - Segments and Related Information and Note 15 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements, which are incorporated by reference, for details pertaining to segment classifications, as well as operating results by segment and for significant customer concentrations.

Backlog

Estimated backlog represents the amount of revenue we expect to realize over the next 18 months from future work on uncompleted contracts, including new contractual agreements on which work has not begun, as well as revenue from change orders and renewal options. Our estimated backlog includes amounts under master service and other service agreements in addition to construction projects and includes our proportionate share of estimated revenue attributable to a contractual joint venture that we proportionately consolidate. We determine the amount of backlog for work under master service and other service agreements based on historical trends, anticipated seasonal impacts and estimates of customer demand based on communications with our customers. The following table presents 18-month backlog by reportable segment, as of the dates indicated, which has been updated to conform to the current period presentation.



	June 30, 2015		March 31, 2015		June 30, 2014
Reportable Segment (in millions):					As Restated
Communications	$	2,895	$	2,862	$	2,600
Oil and Gas	708		850		693
Electrical Transmission	188		212		404
Power Generation and Industrial	259		261		201
Other	20		25		42
Estimated 18-month backlog	$	4,070	$	4,210	$	3,940

We expect to realize approximately 45% of our June 30, 2015 backlog during 2015. Our backlog estimates include amounts under master service agreements, pursuant to which our customers are not contractually committed to purchase a minimum amount of services; and most of these agreements can be canceled on short or no advance notice. Approximately 68% of our estimated backlog as of June 30, 2015 represented amounts under master service or other service agreements. In the past, we have experienced a combination of cancellations and reductions in expected future work from master service agreements as a result of changes in current and planned wireless customer spending. There can be no assurance as to our customers’ requirements or that our estimates are accurate. In addition, timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer delays, regulatory requirements and other project related factors. These changes could cause estimated revenue to be realized in periods later than originally expected, or not at all. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings. For example, due to recent volatility in the oil markets, certain oil and gas projects initially planned for 2015 were canceled or deferred.

Backlog is not a term recognized under U.S. GAAP; however, it is a common measurement used in our industry. Our methodology for determining backlog may not be comparable to the methodologies used by others.

Economic, Industry and Market Factors

We closely monitor the effects that changes in economic and market conditions may have on our customers. General economic and market conditions can negatively affect demand for our customers’ products and services, which can lead to rationalization of our customers’ capital and maintenance budgets in certain end-markets. Fluctuations in market prices for oil, gas and other fuel sources can affect demand for our services, in particular, pipeline and power generation construction services. These fluctuations, as well as the highly competitive nature of our industry, particularly when work is deferred, can result, and in recent years, has resulted in lower bids and lower profit on the services we provide. In the face of increased

pricing pressure, we strive to maintain our profit margins through productivity improvements and cost reduction programs. Fluctuations in market prices for oil, gas and other energy sources can affect demand for our services, in particular, pipeline and power generation construction services. Other market and industry factors, such as (i) changes to our customers’ capital spending plans; (ii) mergers and acquisitions among the customers that we serve, such as the July 2015 acquisition of DIRECTV^® by AT&T; (iii) access to capital for customers in the industries we serve; (iv) changes in technology, tax and other incentives; (v) renewable energy portfolio standards; and (vi) new or changing regulatory requirements affecting the industries we serve, can also affect demand for our services. While we actively monitor economic, industry and market factors affecting our business, we cannot predict the impact such factors may have on our future results of operations, liquidity and cash flows and we may be unable to fully mitigate or take advantage of changes in these factors.

Impact of Seasonality and Cyclical Nature of Business

Our revenue and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, project schedules and timing, in particular, for large non-recurring projects and holidays. Typically, our revenue is lowest in the first quarter of the year because cold, snowy or wet conditions cause project delays. Revenue in the second quarter is typically higher than in the first quarter, as some projects begin, but continued cold and wet weather can often impact second quarter productivity. The third and fourth quarters are typically the most productive quarters of the year, as a greater number of projects are underway and weather is normally more accommodating to construction projects. In the fourth quarter, many projects tend to be completed by customers seeking to spend their capital budgets before the end of the year, which generally has a positive impact on our revenue. However, the holiday season and inclement weather can cause delays, which can reduce revenue and increase costs on affected projects. Any quarter may be positively or negatively affected by adverse or unusual weather patterns, such as excessive rainfall or warm winter weather, making it difficult to predict quarterly revenue and margin variations.

Additionally, our industry can be highly cyclical. Fluctuations in end-user demand within the industries we serve, or in the supply of services within those industries, can impact demand for our services. As a result, our business may be adversely affected by industry declines or by delays in new projects. Variations in project schedules or unanticipated changes in project schedules, in particular, in connection with large construction and installation projects, can create fluctuations in revenue, which may adversely affect us in a given period, even if not in total. In addition, revenue from master service agreements, while generally predictable, can be subject to volatility. The financial condition of our customers and their access to capital; variations in project margins; regional, national and global economic and market conditions; regulatory or environmental influences; and acquisitions, dispositions or strategic investments can also materially affect quarterly results. Accordingly, our operating results in any particular period may not be indicative of the results that can be expected for any other period.

Critical Accounting Estimates

This discussion and analysis of our financial condition and results of operations is based upon our condensed unaudited consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these condensed unaudited consolidated financial statements requires the use of estimates and assumptions that affect the amounts reported in our condensed unaudited consolidated financial statements and the accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Given that management estimates, by their nature, involve judgments regarding future uncertainties, actual results may differ from these estimates if conditions change or if certain key assumptions used in making these estimates ultimately prove to be inaccurate. Our accounting policies and critical accounting estimates are reviewed periodically by the Audit Committee of the Board of Directors. Refer to Note 1 – Business, Basis of Presentation and Significant Accounting Policies in the notes to our condensed unaudited consolidated financial statements of this Quarterly Report on Form 10-Q (this “Form 10-Q”), which is incorporated by reference, and to our 2014 Form 10-K for discussion of our significant accounting policies.

We believe that our accounting estimates pertaining to revenue and cost recognition from percentage-of-completion projects, including related project profit or loss; allowances for doubtful accounts; fair value estimates in connection with business acquisitions, in particular, estimated values of net assets acquired and estimated liabilities for future earn-out obligations; valuations of goodwill and indefinite-lived intangible assets; income taxes; self-insurance liabilities; and litigation and other contingencies are the most critical in the preparation of our consolidated financial statements as they are important to the portrayal of our financial condition and require significant or complex judgment and estimates on the part of management.

The following discussion and analysis of our results of operations should be read in conjunction with our condensed unaudited consolidated financial statements and notes thereto in Item 1 of this Form 10-Q.

Three Months Ended June 30, 2015 Compared to Three Months Ended June 30, 2014

Revenue. Consolidated revenue decreased to $1,067 million from $1,107 million, a decrease of approximately $41 million, or 4%, for the three month period ended June 30, 2015 as compared with the same period in 2014. Oil and Gas revenue increased by $45 million, or 12%, Power Generation and Industrial revenue increased by $9 million, or 9% and Other segment revenue increased by $3 million. These increases were offset by decreases in Communications revenue of $59 million, or 11% and Electrical Transmission revenue of $39 million, or 33%. Acquisitions contributed approximately $112 million of increased revenue, while organic revenue declined by $152 million as compared with the same period in the prior year. The decrease in organic revenue was primarily attributable to lower levels of wireless services in our Communications segment as well as lower levels of revenue in our Electrical Transmission segment. A discussion of revenue by segment follows below.

Communications Segment. Communications revenue was $469 million for the three month period ended June 30, 2015, as compared with $528 million for the same period in 2014, a decrease of $59 million, or 11%. Acquisitions contributed approximately $72 million of increased revenue, whereas organic revenue declined by $131 million as compared with the same period in the prior year, primarily as a result of lower levels of wireless services due to changes in our wireless customers’ capital spending plans as well as the effect of adverse weather disruptions. The decrease in wireless revenue was partially offset by an increase in revenue from certain utility services.

Oil and Gas Segment. Oil and Gas revenue was $411 million for three month period ended June 30, 2015, as compared with $365 million for the same period in 2014, an increase of $45 million, or 12%. Acquisitions contributed $36 million of increased revenue and organic revenue increased by $10 million as compared with the same period in the prior year due to project timing, partially offset by the negative effect of fluctuations in foreign currency exchange rates on our Canadian operations as compared with the same period in the prior year.

Electrical Transmission Segment. Electrical Transmission revenue was $78 million for the three month period ended June 30, 2015, as compared with $117 million for the same period in 2014, a decrease of $39 million, or 33%, due to the effect of adverse weather disruptions, site-related project inefficiencies as well as lower overall levels of project activity. Management’s attention has been diverted from its business operations and marketing due to the Audit Committee independent investigation, and our success rate of obtaining new project awards during 2015 has been below expectations.

Power Generation and Industrial Segment. Power Generation and Industrial revenue was $103 million for the three month period ended June 30, 2015, as compared with $95 million for the same period in 2014, an increase of $9 million, or 9%. The increase was driven by higher levels of renewable power projects as compared with the same period in the prior year.

Other Segment. Other segment revenue totaled approximately $7 million for the three month period ended June 30, 2015 as compared with $4 million for the same period in 2014, an increase of $3 million, driven primarily by an increase in revenue from a proportionately consolidated non-controlled Canadian joint venture, which we acquired in June 2014, offset by a decrease in other international operations.

Costs of revenue, excluding depreciation and amortization. Costs of revenue, excluding depreciation and amortization, decreased by $5 million, or 1%, to $946 million for the three month period ended June 30, 2015 as compared with $951 million for the same period in 2014. Lower revenue contributed a $35 million decrease in costs of revenue, excluding depreciation and amortization, whereas decreased productivity resulted in an increase of approximately $30 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue increased by approximately 280 basis points, from 85.9% of revenue for the three month period ended June 30, 2014, to 88.7% of revenue for the same period in 2015. The basis point increase was primarily driven by increased costs in our Electrical Transmission segment due to the effects of adverse weather disruptions, site-related project inefficiencies and lower levels of cost utilization from reduced levels of revenue. The increase in costs of revenue, excluding depreciation and amortization, as a percent of revenue, in our Electrical Transmission segment was partially offset by productivity improvements in our Oil and Gas segment and in our Power Generation and Industrial segment.

Depreciation and amortization. Depreciation and amortization was $43 million, or 4.1% of revenue for the three month period ended June 30, 2015 as compared with $37 million in 2014, or 3.3% of revenue, an increase of approximately $6 million, or 17.7%. Acquisitions contributed $7 million of increased depreciation and amortization expense, whereas organic depreciation and amortization expense decreased by $1 million as compared with the same period in the prior year.

General and administrative expenses. General and administrative expenses were $69 million, or 6.5% of revenue for the three month period ended June 30, 2015, as compared with $54 million, or 4.9% of revenue for the same period in 2014, an increase of approximately $15 million, or 27.7%. Acquisitions contributed approximately $2 million of incremental general and administrative costs, exclusive of acquisition integration costs associated with the WesTower acquisition. Acquisition integration costs and Audit Committee independent investigation expenses contributed $8 million and $7 million, respectively, of the increase in general and administrative expenses in the second quarter of 2015. These increases were offset by a decrease in stock-based compensation expense for the three month period ended June 30, 2015 as compared with the same period in the prior year.

Interest expense, net. Interest expense, net of interest income, was flat at $12.9 million, or 1.2% of revenue for the three month periods ended June 30, 2015 and 2014. In 2014, our senior convertible notes matured and were converted, which reduced our interest expense in 2015. The decrease in interest expense in 2015 from our senior convertible notes was offset by incremental interest expense on our Credit Facility as a result of higher average outstanding borrowings, as well as $0.8 million of consent solicitation agent fees incurred in the second quarter of 2015 due to the delay in filing of our 2014 Form 10-K and the First Quarter Form 10-Q.

Other income, net. For the three month periods ended June 30, 2015 and 2014, other income, net, was $2 million. Other (income) expense, net, consists primarily of gains or losses from sales of assets and investments, certain legal settlements, income or expense from equity method investments and gains or losses from changes to estimated earn-out accruals. Gains on sales of equipment for both the three month periods ended June 30, 2015 and 2014 were approximately $1 million. Other income, net, for the three month period ended June 30, 2015, includes approximately $3 million of losses on equity method investments, which was offset by a net reduction in the estimated earn-out liability for acquired businesses.

(Provision for) benefit from income taxes. Income tax expense was $1 million for the three month period ended June 30, 2015, as compared with $21 million for the same period in the prior year. Income tax expense for the three month period ended June 30, 2015 included approximately $3 million of expense incurred in connection with the cumulative revaluation of certain deferred tax liabilities pursuant to an Alberta provincial income tax law that was enacted as of June 29, 2015. This income tax expense was offset, in part, by an income tax benefit for the three month period ended June 30, 2015. In the second quarter of 2015, we had a pre-tax loss of $2 million as compared with pre-tax income of $54 million for the same period in the prior year. Excluding the effect of the Alberta income tax expense, our tax rate for the three month period ended June 30, 2015 increased versus the same period in 2014 due to lower than expected levels of taxable income from our Canadian operations in 2015.

Analysis of EBITDA by Segment

Communications Segment. EBITDA for our Communications segment was $41 million, or 8.6% of revenue, for the three month period ended June 30, 2015 as compared with $58 million, or 10.9% of revenue, for the same period in 2014, a $17 million, or 30% decrease. Communications segment EBITDA for the three month period ended June 30, 2015 includes approximately $8 million of acquisition integration costs associated with the WesTower acquisition. As a percentage of revenue, EBITDA decreased by 230 basis points, or approximately $11 million, primarily as a result of previously

mentioned acquisition integration costs, lower levels of cost utilization due to reduced levels of wireless revenue as well as the effect of adverse weather disruptions.

Oil and Gas Segment. EBITDA for our Oil and Gas segment was $41 million, or 10.1% of revenue, for the three month period ended June 30, 2015 as compared with $36 million, or 9.9% of revenue, for the same period in 2014, an increase of $5 million, or 14%, due primarily to higher levels of revenue. As a percentage of revenue, Oil and Gas segment EBITDA increased by approximately 20 basis points, or approximately $1 million, due to project efficiencies.

Electrical Transmission Segment. EBITDA for our Electrical Transmission segment was negative $21 million, or negative 27.4% of revenue, for the three month period ended June 30, 2015 as compared with positive EBITDA of $19 million, or positive 16.5% of revenue, for the same period in 2014, a decrease of $41 million. This segment has been the primary focus of the Audit Committee independent investigation, which has significantly diverted management’s attention from its operations and marketing efforts. For the three month period ended June 30, 2015 the decrease in EBITDA was due to the effects of adverse weather disruptions, site-related project inefficiencies and lower levels of cost utilization from reduced levels of revenue as compared with the same period in the prior year.

Power Generation and Industrial Segment. EBITDA for our Power Generation and Industrial segment was $8 million, or 7.8% of revenue, for the three month period ended June 30, 2015, as compared with EBITDA of $4 million, or 4.1% of revenue for the same period in 2014, an increase of approximately $4 million. As a percentage of revenue, Power Generation and Industrial segment EBITDA increased by approximately 370 basis points, or approximately $4 million, due to project efficiencies and improved cost utilization from higher levels of revenue.

Other Segment. EBITDA from Other businesses generally flat as compared with the prior year.

Corporate. Corporate EBITDA was negative $15 million for the three month period ended June 30, 2015, as compared with negative EBITDA of $13 million for the same period in 2014. Corporate EBITDA for the three month period ended June 30, 2015 includes $7 million of costs related to the Audit Committee independent investigation. This increase was offset, in part, by a net reduction in the estimated earn-out liability for acquired businesses and a reduction in stock-based compensation expense.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Revenue. Consolidated revenue increased to $2,070 million from $2,065 million, an increase of approximately $5 million, or 0.2%, for the six month period ended June 30, 2015 as compared with the same period in 2014. Power Generation and Industrial revenue increased by $39 million, or 26%, Electrical Transmission revenue increased by $4 million, or 2% and Other segment revenue increased by $7 million. These increases were offset, in part, by a decrease in Communications revenue of $36 million, or 4% and Oil and Gas revenue, which decreased by $8 million, or 1%. Acquisitions contributed approximately $232 million of increased revenue, while organic revenue declined by $227 million as compared with the same period in the prior year. The decrease in organic revenue was primarily attributable to lower levels of wireless projects in our Communications segment, as well as lower levels of revenue in our Oil and Gas segment. A discussion of revenue by segment follows below.

Communications Segment. Communications revenue was $939 million for the six month period ended June 30, 2015, as compared with $975 million for the same period in 2014, a decrease of $36 million, or 4%. Acquisitions contributed approximately $140 million of increased revenue, whereas organic revenue declined by $176 million as compared with the same period in the prior year, primarily as a result of lower levels of wireless services due to changes in our wireless customers’ capital spending plans as well as the effect of adverse weather disruptions. The decrease in wireless revenue was partially offset by an increase in revenue from certain utility services.

Oil and Gas Segment. Oil and Gas revenue was $737 million for six month period ended June 30, 2015, as compared with $745 million for the same period in 2014, a decrease of $8 million, or 1%. Acquisitions contributed $89 million of increased revenue, while organic revenue declined by $97 million as compared with the same period in the prior year. The decline in organic revenue resulted from completion of a large long-haul pipeline project in 2014, for which there was not a replacement project in 2015, the negative effect of fluctuations in foreign currency exchange rates on our Canadian operations as compared with the same period in the prior year and from lower levels of project activity as a result of the decline in oil prices.

Electrical Transmission Segment. Electrical Transmission revenue was $194 million for the six month period ended June 30, 2015, as compared with $191 million for the same period in 2014, an increase of $4 million, or 2%. Electrical transmission revenue for the six month period ended June 30, 2015 included the effect of adverse weather disruptions and site-related project inefficiencies as well as lower than expected levels of project activity. Management’s attention has been diverted from its business operations and marketing due to the Audit Committee independent investigation, and our success rate of obtaining new project awards during 2015 has been below expectations.

Power Generation and Industrial Segment. Power Generation and Industrial revenue was $187 million for the six month period ended June 30, 2015, as compared with $149 million for the same period in 2014, an increase of $39 million, or 26%. The increase was driven by higher levels of renewable power projects as compared with the same period in the prior year.

Other Segment. Other segment revenue totaled approximately $13 million for the six month period ended June 30, 2015 as compared with $6 million for the same period in 2014, an increase of $7 million, driven by increased operations in Mexico, as well as an increase in revenue from a proportionately consolidated non-controlled Canadian joint venture, which we acquired in June 2014.

Costs of revenue, excluding depreciation and amortization. Costs of revenue, excluding depreciation and amortization, increased by $40 million, or 2%, to $1,832 million for the six month period ended June 30, 2015 from $1,792 million for the same period in 2014. Approximately $4 million of this increase was due to higher revenue and approximately $36 million was driven by decreased productivity. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue increased by approximately 170 basis points, from 86.8% of revenue for the six month period ended June 30,

2014, to 88.5% of revenue for the same period in 2015. The basis point increase was driven by increased costs in our Electrical Transmission, Power Generation and Industrial and Other segments. The primary driver of the basis point increase was due to increased costs in our Electrical Transmission segment due to the effects of adverse weather disruptions, site-related project inefficiencies and lower levels of cost utilization from reduced levels of revenue. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue also increased in our Power Generation and Industrial segment due to first quarter 2015 project losses of approximately $16 million on a troubled wind project in Canada, and in our Other business segment from first quarter 2015 project losses of approximately $6 million on a non-controlled Canadian joint venture. These increases in costs of revenue, excluding depreciation and amortization, as a percent of revenue, were partially offset by productivity improvements in our Communications segment.

Depreciation and amortization. Depreciation and amortization was $86 million, or 4.1% of revenue for the six month period ended June 30, 2015 as compared with $70 million, or 3.4% of revenue for the same period in 2014, an increase of approximately $16 million, or 22.2%. Acquisitions contributed $15 million of the increase in depreciation and amortization expense.

General and administrative expenses. General and administrative expenses were $143 million, or 6.9% of revenue for the six month period ended June 30, 2015, as compared with $108 million, or 5.2% of revenue for the same period in 2014, an increase of approximately $36 million, or 33.2%. Acquisitions contributed approximately $6 million of incremental general and administrative costs, exclusive of acquisition integration costs associated with the WesTower acquisition. Acquisition integration costs and Audit Committee independent investigation expenses contributed $17 million and $10 million, respectively, of the increase in general and administrative expenses in the first half of 2015. The remaining increase in general and administrative expenses was attributable to an increase in various administrative costs, including employee and legal costs, partially offset by a decrease in stock-based compensation expense.

Interest expense, net. Interest expense, net of interest income, was $24 million, or 1.2% of revenue for the six month period ended June 30, 2015, as compared with $25 million, or 1.2% of revenue for the same period in 2014. In 2014, our senior convertible notes matured and were converted, which reduced our interest expense in 2015. The decrease in interest expense in 2015 from our senior convertible notes was offset by incremental interest expense on our Credit Facility as a result of higher average outstanding borrowings, as well as $0.8 million of consent solicitation agent fees incurred in the second quarter of 2015 due to the delay in filing of our 2014 Form 10-K and the First Quarter Form 10-Q.

Other income, net. Other income, net, was $2 million for the six month period ended June 30, 2015, as compared with $4 million for the same period in 2014. Other (income) expense, net, consists primarily of gains or losses from sales of assets and investments, certain legal settlements, income or expense from equity method investments and gains or losses from changes to estimated earn-out accruals. Gains on sales of equipment for the six month periods ended June 30, 2015 and 2014 were approximately $1 million and $3 million, respectively. Other income, net, for the six month period ended June 30, 2015 includes approximately $3 million of losses on equity method investments, which was offset by a net reduction in the estimated earn-out liability for acquired businesses.

(Benefit from) provision for income taxes. Income tax benefit was $3 million for the six month period ended June 30, 2015, as compared with income tax expense of $28 million for the same period in 2014. The income tax benefit for the six month period ended June 30, 2015 resulted from pre-tax losses of $13 million as compared with pre-tax income of $74 million for the same period in the prior year, offset in part by the effect of second quarter 2015 tax expense of approximately $3 million incurred in connection with the cumulative revaluation of certain deferred tax liabilities pursuant to an Alberta provincial income tax law that was enacted as of June 29, 2015, as well as the effect of a higher tax rate. Excluding the effect of the Alberta income tax expense, our tax rate for the six month period ended June 30, 2015 was 44.5%, as compared with 38.0% for the same period in 2014 due to lower than expected levels of taxable income from our Canadian operations in 2015.

Analysis of EBITDA by Segment

Communications Segment. EBITDA for our Communications segment was $92 million, or 9.8% of revenue, for the six month period ended June 30, 2015 as compared with $101 million, or 10.4% of revenue, for the same period in 2014, a $9 million, or 9% decrease. Communications segment EBITDA for the six month period ended June 30, 2015 includes approximately $17 million of acquisition integration costs associated with the WesTower acquisition. As a percentage of revenue, EBITDA decreased by 60 basis points, or approximately $6 million, primarily as a result of acquisition integration costs from the WesTower acquisition, offset in part by production efficiencies and improved cost utilization.

Oil and Gas Segment. EBITDA for our Oil and Gas segment was $63 million, or 8.5% of revenue, for the six month period ended June 30, 2015 as compared with $71 million, or 9.5% of revenue, for the same period in 2014, a decrease of $8 million, or 11%. As a percentage of revenue, Oil and Gas segment EBITDA decreased by approximately 100 basis points, or approximately $7 million, due to production inefficiencies resulting from lower levels of revenue due to completion of a large long-haul pipeline project in 2014 for which there was not a replacement project in 2015, the negative effect of fluctuations in foreign currency exchange rates on our Canadian operations as compared with the same period in the prior year and from lower levels of project activity as a result of the decline in oil prices.

Electrical Transmission Segment. EBITDA for our Electrical Transmission segment was negative $24 million for the six month period ended June 30, 2015, or negative 12.3% of revenue, as compared with positive EBITDA of $17 million, or positive 8.7% of revenue, for the same period in 2014, a decrease of $40 million. This segment has been the primary focus of the Audit Committee independent investigation, which has significantly diverted management’s attention from its operations and marketing efforts. The decrease in EBITDA was due to the effects of adverse weather disruptions, site-related project inefficiencies and lower levels of cost utilization from reduced levels of revenue as compared with the same period in the prior year.

Power Generation and Industrial Segment. EBITDA for our Power Generation and Industrial segment was negative $1 million for the six month period ended June 30, 2015, or negative 0.5% of revenue, as compared with positive EBITDA of $4 million, or positive 3.0% of revenue, for the same period in 2014, a decrease of approximately $5 million. Power Generation and Industrial segment EBITDA includes $16 million of first quarter 2015 losses on a troubled wind project in Canada. For the six month period ended June 30, 2015, these project losses were partially offset by project efficiencies and improved cost utilization from higher levels of revenue.

Other Segment. EBITDA from Other businesses was negative $5 million for the six month period ended June 30, 2015, as compared with $1 million of EBITDA for the same period in 2014. The decrease in EBITDA was driven primarily by $6 million of first quarter 2015 losses on a proportionately consolidated non-controlled Canadian joint venture that was acquired in 2014 and experienced project delays.

Corporate. Corporate EBITDA was negative $29 million for the six month period ended June 30, 2015, as compared with negative EBITDA of $24 million for the same period in 2014. Corporate EBITDA for the six month period ended June 30, 2015 includes $10 million of costs related to the Audit Committee independent investigation. For the six month period ended June 30, 2015, Corporate EBITDA also includes increases in various administrative costs, including employee and legal costs, offset, in part, by a net reduction in the estimated earn-out liability for acquired businesses and a reduction in stock-based compensation expense.

Foreign Operations

We have operations in Canada, Mexico and in other countries in Latin America. See Note 14 - Segments and Related Information in the notes to the condensed unaudited consolidated financial statements, which is incorporated by reference.

Non-U.S. GAAP Financial Measures

As appropriate, we supplement our reported U.S. GAAP financial information with certain non-U.S. GAAP financial measures, including earnings from continuing operations before interest, income taxes, depreciation and amortization (“EBITDA”). In addition, we have presented “Adjusted EBITDA,” as well as adjusted net income from continuing operations (“Adjusted Net Income From Continuing Operations”) and adjusted diluted earnings per share from continuing operations (“Adjusted Diluted Earnings Per Share From Continuing Operations”). All of these “adjusted” non-U.S GAAP measures exclude non-cash stock-based compensation expense, acquisition integration costs resulting from the WesTower acquisition, Audit Committee independent investigation related costs and project losses on a non-controlled joint venture. See Note 10 - Stock-Based Compensation and Other Employee Benefit Plans, Note 3 - Acquisitions, Note 14 - Segments and Related Information and Note 15 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements, which are incorporated by reference. The definitions of EBITDA and Adjusted EBITDA above are not the same as in our Credit Facility or in the indenture governing our notes; therefore, EBITDA and Adjusted EBITDA as presented in this discussion should not be used for purposes of determining our compliance with the covenants contained in our debt instruments.

We use EBITDA, Adjusted EBITDA, Adjusted Net Income From Continuing Operations and Adjusted Diluted Earnings Per Share From Continuing Operations to evaluate our performance, both internally and as compared with our peers, because these measures exclude certain items that may not be indicative of our core operating results, as well as items that can vary widely across different industries or among companies within the same industry. Additionally, these measures provide a baseline for analyzing trends in our underlying business. Management also considers EBITDA and Adjusted EBITDA as indicators of our ability to generate cash to service debt, fund capital expenditures and expand our business, but management does not consider the presented non-U.S. GAAP financial measures as measures of our liquidity. While EBITDA and Adjusted EBITDA are measures of our ability to generate cash, these measures exclude the cash impact of changes in our assets and liabilities as well as interest and income taxes. Net cash provided by operating activities in the consolidated statements of cash flows accounts for these changes in our assets and liabilities.

We believe these non-U.S. GAAP financial measures provide meaningful information and help investors understand our financial results and assess our prospects for future performance. Because non-U.S. GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-U.S. GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported net (loss) income from continuing operations, diluted (loss) earnings per share from continuing operations and net cash provided by operating activities, and should be viewed in conjunction with the most comparable U.S. GAAP financial measures and the provided reconciliations thereto. We believe these non-U.S. GAAP financial measures, when viewed together with our U.S. GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

The following table presents a reconciliation of EBITDA and Adjusted EBITDA to net (loss) income from continuing operations, in dollar and percentage of revenue terms, for the periods indicated (dollar amounts in millions).

Adjusted Income From Continuing Operations and Adjusted Diluted Earnings Per Share From Continuing Operations

The table below reconciles Adjusted Net Income From Continuing Operations and Adjusted Diluted Earnings Per Share From Continuing Operations with reported net (loss) income from continuing operations and reported diluted earnings (loss) per share from continuing operations, the most directly comparable U.S. GAAP financial measures. Adjustments have been tax-effected using the effective tax rate from continuing operations for the respective periods, excluding certain discrete items. For both the three and six month periods ended June 30, 2015, because the reported loss from continuing operations, on an adjusted basis is income from continuing operations, we included an additional 0.5 million weighted average common stock equivalents in our diluted share count to calculate adjusted diluted earnings per share for the respective periods.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from continuing operations, availability under our Credit Facility and our cash balances. Our primary liquidity needs are for working capital, income taxes, capital expenditures, insurance collateral in the form of cash and letters of credit, earn-out obligations, equity, joint venture and other investments and debt service. We also evaluate opportunities for strategic acquisitions and investments from time to time, and we may consider opportunities to repurchase, refinance or retire outstanding debt or repurchase additional shares of our outstanding common stock in the future, any of which may require our use of cash.

Capital Expenditures. We estimate that we will spend approximately $70 million in 2015 on capital expenditures, or approximately $60 million, net of asset disposals. We expect to incur approximately $40 million to $50 million of equipment purchases under capital lease or other financing arrangements. For the six month period ended June 30, 2015, we spent approximately $48 million on capital expenditures, or $44 million net of asset disposals, and incurred approximately $27 million of equipment purchases under capital lease and other financing arrangements. Actual capital expenditures may increase or decrease from estimates depending upon business activity levels. We will continue to evaluate lease versus buy decisions to meet our equipment needs and, based on this evaluation, our capital expenditures may increase or decrease in the future.

Acquisition-Related Contingent Consideration. In most of our acquisitions, we have agreed to make future earn-out payments to the sellers, which are contingent upon the future earnings performance of the acquired businesses. Certain earn-out payments may be paid in either cash or, under specific circumstances, MasTec common stock, or a combination thereof, at our option. The estimated total value of earn-out obligations recorded as liabilities as of June 30, 2015 was approximately $108 million. Of this amount, $13 million represents the liability for earn-out obligations that have been earned. The remainder, $95 million, is management’s estimate of potential earn-out obligations that are contingent upon future performance. Potential future earn-out obligations for acquisitions after January 1, 2009 are measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in earnings as a component of other income or expense, in accordance with U.S. GAAP. Earn-outs for acquisitions completed prior to January 1, 2009 are recorded as additional goodwill as earned. During the three and six month periods ended June 30, 2015 and 2014, we made cash payments of $39 million and $59 million, respectively, related to earn-out obligations.

Income Taxes. Cash tax payments, net of tax refunds, were $5 million for the six month period ended June 30, 2015 as compared with $30 million for the six month period ended June 30, 2014. Quarterly tax payments are based on estimates of full year taxable income activity and estimated tax rates. Our cash tax payments, which decreased in the first half of 2015 as compared with 2014 due to a reduction in income, vary from period to period with changes in taxable income and earnings estimates.

Working Capital. We need working capital to support seasonal variations in our business, primarily due to the impact of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support related customer demand. Our business is typically slower in the first quarter of each calendar year. Working capital needs are generally higher during the summer or fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate. Conversely, working capital needs are typically converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.

Working capital needs also tend to increase when we commence multiple projects or particularly large projects because labor, including subcontractor costs, and certain other costs, including inventory, become payable before the receivables resulting from work performed are billed and collected. Timing of billing milestones and project close-outs can contribute to changes in unbilled revenue. As of June 30, 2015, we expect that substantially all of our costs in excess of billings and earnings will be billed to customers in the normal course of business within the next twelve months. Accounts receivable balances, which consist of contract billings as well as costs and earnings in excess of billings and retainage, decreased to $1.1 billion as of June 30, 2015 from $1.3 billion as of December 31, 2014, due to lower levels of quarterly revenue in the second quarter of 2015 as compared with the fourth quarter of 2014, as well as working capital initiatives. Inventory balances decreased from $113 million as of December 31, 2014 to $103

million as of June 30, 2015, primarily due to utilization of wireless project inventories, which increased during 2014 due to inventory from acquired businesses as well as from increases in wireless project inventories. We anticipate that wireless inventories will decrease in 2015 as these amounts are utilized.

Our billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount (generally from 5% to 10%) until the job is completed. For certain customers, we maintain inventory to meet the materials requirements of the contracts. Occasionally, certain of our customers pay us in advance for a portion of the materials we purchase for their projects, or allow us to pre-bill them for materials purchases up to specified amounts. Vendor terms are generally 30 days. Our agreements with subcontractors often contain a “pay-if-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.

Settlement of Convertible Notes. In 2014, our senior convertible notes, in an original principal amount of $215 million, matured and were converted by the holders. We paid $202 million in cash using proceeds from our Credit Facility and issued 6.6 million shares of our common stock in respect thereof. The shares issued included 5.8 million premium shares, which represented the conversion value of certain of the convertible notes in excess of their principal amount. See discussion in Note 10 - Debt in the notes to the audited consolidated financial statements included in our 2014 Form 10-K.

Summary of Financial Condition, Liquidity and Capital Resources

We anticipate that funds generated from operations, borrowings under our Credit Facility and our cash balances will be sufficient to meet our working capital requirements, required income tax payments, debt service obligations, anticipated capital expenditures, equity, joint venture and other investments, insurance collateral requirements, earn-out obligations and letters of credit for at least the next twelve months.

Sources and Uses of Cash

As of June 30, 2015, we had $501 million in working capital, defined as current assets less current liabilities, as compared with $551 million as of December 31, 2014, a decrease of approximately $50 million. Our working capital has decreased, primarily as a result of lower levels of quarterly revenue in the second quarter of 2015 as compared with the fourth quarter of 2014. Total cash and cash equivalents of $5 million as of June 30, 2015 decreased by $19 million from total cash and cash equivalents of $24 million as of December 31, 2014.

Sources and uses of cash are summarized below (in millions):



	For the Six Months Ended June 30,
	2015			2014
				As Restated
Net cash provided by operating activities	$	165.9		$	55.3
Net cash used in investing activities	$	(114.2	)	$	(221.1	)
Net cash (used in) provided by financing activities	$	(70.4	)	$	159.2

Operating Activities. Cash flow from operations is primarily influenced by demand for our services and operating margins, but can also be affected by working capital needs associated with the various types of services we provide. Working capital is affected by changes in accounts receivable, costs and earnings in excess of billings and billings in excess of costs and earnings, all of which tend to be related. These working capital items are also generally affected by changes in revenue resulting from both the timing and the volume of work performed, by variability in the timing of customer billings and collections of receivables, as well as settlement of payables and other obligations. Net cash provided by operating activities for the six month period ended June 30, 2015 was $166 million, as compared with $55 million of net cash provided by operating activities for the same period in 2014. Net changes in assets and liabilities had a positive impact on cash provided by operating activities of $175 million, related largely to changes in accounts receivable and inventory levels, net of acquired businesses, offset, in part, by changes in accounts payable and accrued expenses. The positive effect of net changes in assets and liabilities was partially offset by a net loss of $10 million for the six month period ended June 30, 2015 as compared with net income of $46 million in the 2014 period.

Days sales outstanding (“DSO”), net of billings in excess of costs and earnings was 86 as of June 30, 2015, as compared with 88 as of March 31, 2015, and 92, as adjusted for acquisitions, as of June 30, 2014. DSO, net of billings in excess of costs and earnings, is calculated as accounts receivable, net, less billings in excess of costs and earnings, divided by average daily revenue for the most recently completed quarter as of the balance sheet date. The decrease in DSO is primarily attributable to timing of collections on certain projects and changes in project and customer mix, as well as improved payment terms, which reduced the collection cycle time for certain receivables, and the settlement of certain litigation matters. Other than matters subject to litigation, we do not anticipate material collection issues related to our outstanding accounts receivable balances, nor do we have material amounts due from customers experiencing financial difficulties. We expect to collect substantially all of our outstanding accounts receivable, net, within the next twelve months.

Investing Activities. Net cash used in investing activities decreased by $107 million to $114 million for the six month period ended June 30, 2015 from $221 million for the six month period ended June 30, 2014. There were no acquisition-related payments for the six month period ended June 30, 2015 as compared with $163 million in the prior year period. We spent $48 million on capital expenditures for the six month period ended June 30, 2015, or $44 million net of asset disposals, as compared with capital expenditures, net of asset disposals, of $59 million for the same period in the prior year, a decrease of $15 million. Total capital additions, including capital lease and other financing arrangements, have decreased from $118 million for the six month period ended June 30, 2014 to $76 million for the six month period ended June 30, 2015. The decrease in cash used in investing activities from acquisition-related activities and capital expenditures was offset, in part, by an increase of $70 million in payments for other investments,

related primarily to activity associated with our equity method investees and contractual joint venture. See Note 3 - Acquisitions and Note 5 - Fair Value of Financial Instruments, which notes are incorporated by reference, for discussion of our cost and equity method investments, including our recent investment in two joint ventures related to the construction of pipelines that are planned to interconnect as the U.S./Mexico border.

Financing Activities. Net cash used in financing activities for the six month period ended June 30, 2015 was $70 million, as compared with cash provided by financing activities of $159 million for the six month period ended June 30, 2014, an increase in cash used of approximately $230 million. For the six month period ended June 30, 2015, we paid $100 million to repurchase shares our common stock under our 2014 Share Repurchase Program, whereas for the same period in 2014, we paid $105 million in settlement of our 4.0% Convertible Notes. Credit facility related activity, net, for the six month period ended June 30, 2015, totaled $103 million of borrowings, net of repayments, compared to $352 million of borrowings, net of repayments, for the six month period ended June 30, 2014, for a decrease in cash provided by financing activities from credit facility-related activities, net, of $249 million. Payments of acquisition-related contingent consideration for the six month period ended June 30, 2015 decreased by $20 million as compared with the same period in the prior year.

We have a senior secured credit facility, which we refer to as the Credit Facility. Under the Credit Facility, aggregate borrowing commitments total $1.25 billion, composed of $1.0 billion of revolving commitments and a term loan in the aggregate principal amount of $250 million (the “Term Loan”). The Credit Facility provides the ability to borrow in either Mexican pesos or Canadian dollars, up to an aggregate equivalent amount of $200 million. Revolving commitments under the Credit Facility mature on October 29, 2018, and the Term Loan matures on November 21, 2019. The Term Loan is subject to amortization in quarterly principal installments of $3.1 million, subject to reduction as a result of the application of certain prepayments in accordance with the terms of the Credit Facility, commencing as of the quarter ending March 31, 2016 and continuing for each fiscal quarter thereafter. The maximum amount available for letters of credit under the Credit Facility is $450 million, of which up to $100 million can be denominated in either Mexican pesos or Canadian dollars. The Credit Facility also provides for swing line loans of up to $75 million. Under the Credit Facility, we have the option to increase revolving commitments and/or establish additional term loan tranches in an aggregate amount of $250 million. Borrowings under the Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including equity, joint venture or other investments, the repurchase or prepayment of indebtedness and share repurchases.

Interest on outstanding revolving loans and the Term Loan under the Credit Facility accrues at variable rates based, at our option, on a Eurocurrency rate, as defined in the Credit Facility, plus a margin, or a base rate, as defined in the Credit Facility, plus a margin. As of June 30, 2015, we had $356.1 million of outstanding revolving loans under the Credit Facility, which accrued interest at a weighted average interest rate of 2.52%, and $175.8 million of issued letters of credit, which mature at various dates. Letter of credit fees accrued at 0.875% per annum for performance standby letters of credit and 1.75% for financial standby letters of credit. The Term Loan accrued interest at a rate of 1.94% as of June 30, 2015. Borrowing capacity of $468.2 million as of June 30, 2015 was available for revolving loans or up to $274.2 million for new letters of credit. The unused facility fee was 0.35% as of June 30, 2015. The Credit Facility is guaranteed by certain of our subsidiaries (the “Guarantor Subsidiaries”) and the obligations under the Credit Facility are secured by substantially all of our and the Guarantor Subsidiaries’ respective assets, subject to certain exceptions.

Based upon current availability under our Credit Facility, our liquidity and our anticipated cash flows, we believe we will be in compliance with the Credit Facility’s terms and conditions for the next twelve months. We are dependent upon borrowings and letters of credit under the Credit Facility to fund our operations. Should we be unable to comply with the terms and conditions of the Credit Facility, we would be required to obtain modifications to the Credit Facility or obtain an alternative source of financing to continue to operate, neither of which may be available to us on commercially reasonable terms, or at all. The Credit Facility is subject to certain provisions and covenants, as more fully described in Note 10 - Debt in the notes to the audited consolidated financial statements included in the 2014 Form 10-K, including a requirement to deliver periodic financial statements to the bank group under the Credit Facility. In connection with the delayed filing of our 2014 Form 10-K and First Quarter 2015 Form 10-Q, we received consents from our bank group, which extended the delivery date requirements of our audited consolidated financial statements for the year ended December 31, 2014 and our condensed unaudited consolidated financial statements for the quarter ended March 31, 2015. With the filing of our First Quarter 2015 Form 10-Q, we met the reporting requirements with respect to our Credit Facility.

Other Credit Facilities. We have other credit facilities to support the working capital requirements of our foreign operations, which have varying dates of maturity and are generally renewed on an annual basis. Borrowings under these credit facilities are primarily denominated in Canadian dollars and maximum borrowing capacity totaled approximately $36.0 million as of June 30, 2015. Outstanding borrowings, which accrued interest at a weighted average rate of 3.9%, totaled approximately $26.0 million as of June 30, 2015.

4.875% Senior Notes

We have $400 million outstanding principal amount of 4.875% Senior Notes, which are subject to certain provisions and covenants, as more fully described in Note 10 - Debt in the notes to the audited consolidated financial statements included in the Company’s 2014 Form 10-K, including a requirement to file with the SEC annual and quarterly reports. In connection with the delayed filing of our 2014 Form 10-K and First Quarter 2015 Form 10-Q, we received a consent from our Note Holders that extended these reporting requirements to August 1, 2015, subject to a 60-day cure period. With the filing of our First Quarter 2015 Form 10-Q, we met the reporting requirements with respect to our 4.875% Senior Notes. We paid a 25 basis point fee, or $0.9 million, to our Note Holders, and a 20 basis point fee, or $0.8 million, to the solicitation agent in connection with this consent.

Senior Convertible Notes

Our senior convertible notes, which matured in 2014, were composed of $202 million aggregate principal amount of senior convertible notes issued in 2011 and approximately $13 million aggregate principal amount of senior convertible notes issued in 2009. In accordance with our previously stated intent, we settled the $202 million principal amount of the 2011 Convertible Notes in cash and the premium value in shares, resulting in the issuance of 5.8 million shares of our common stock. Upon maturity of the 2009 Convertible Notes, we issued 0.8 million shares of our common stock.

Debt Guarantees and Covenants

The 4.875% Senior Notes are senior unsecured unsubordinated obligations and rank equal in right of payment with existing and future unsubordinated debt, and rank senior in right of payment to existing and future subordinated debt and are fully and unconditionally guaranteed on an unsecured, unsubordinated, joint and several basis by certain of our existing and future 100%-owned direct and indirect domestic subsidiaries that are each guarantors of the Credit Facility or other outstanding indebtedness. See Note 17 - Supplemental Guarantor Condensed Unaudited Consolidating Financial Information in the notes to the condensed unaudited consolidated financial statements, which is incorporated by reference.

We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of June 30, 2015.

Additional Information

For detailed discussion and additional information pertaining to our debt instruments, see Note 10 - Debt in the notes to the audited consolidated financial statements included in our 2014 Form 10-K. Also see Note 8 - Debt in the notes to the condensed unaudited consolidated financial statements in this Quarterly Report on Form 10-Q for current period balances and discussion, which is incorporated by reference.

Off-balance sheet arrangements

As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases, letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, self-insurance liabilities, liabilities associated with multi-employer pension plans, liabilities associated with certain indemnification and guarantee arrangements and obligations relating to our non-consolidated affiliates, joint venture arrangements and variable interest entities. Refer to Note 15 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements, which is incorporated by reference, for current period details pertaining to our off-balance sheet arrangements. See Note 3 - Acquisitions and Note 5 - Fair Value of Financial Instruments for discussion pertaining to certain of our cost and equity method investments and other investment arrangements, which notes are incorporated by reference.

Impact of Inflation

The primary inflationary factors affecting our operations are labor and fuel costs, and to a lesser extent, material costs. The prices of oil and gas are subject to unexpected fluctuations due to events outside of our control, including geopolitical events and fluctuations in global supply and demand. An example is the recent volatility experienced by the oil markets due to declining oil prices beginning in the latter part of 2014. We closely monitor inflationary factors and any impact they may have on our operating results or financial condition.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

As of June 30, 2015, our variable interest rate debt was primarily related to our Credit Facility. Interest on outstanding revolving loans under our Credit Facility accrues at variable rates based, at our option, on a Eurocurrency rate, as defined in the Credit Facility, plus a margin, or a base rate, as defined in the Credit Facility, plus a margin. Interest on our Term Loan under the Credit Facility accrues at a variable rate based, at our option, on either a Eurocurrency rate or base rate, each as defined in the Credit Facility, in each case, plus a margin. As of June 30, 2015, we had $356 million aggregate principal amount of outstanding revolving loans under our Credit Facility with a weighted average interest rate of 2.52% and a Term Loan with a balance of $250 million with an interest rate of 1.94%. Interest on letters of credit issued under our Credit Facility as of June 30, 2015 accrued at 0.875% per annum for performance standby letters of credit and at 1.75% per annum for financial standby letters of credit. A 100 basis point increase in the applicable interest rates under our Credit Facility would not have had a material impact on our results of operations for the three or six month periods ended June 30, 2015.

As of June 30, 2015, our fixed interest rate debt primarily included $400 million aggregate principal amount of 4.875% Senior Notes and $23 million of notes payable for equipment, which had a weighted average interest rate of approximately 2.7%. None of this debt subjects us to interest rate risk, but we may be subject to changes in interest rates if and when we refinance this debt at maturity or otherwise.

Foreign Currency Risk

We have operations in Canada, Mexico and in other countries in Latin America. Revenue generated from foreign operations represented 14% and 16% of our total revenue for the three and six month periods ended June 30, 2015, respectively. Revenue and expense related to our foreign operations are, for the most part, denominated in the functional currency of the foreign operation, which minimizes the impact that fluctuations in exchange rates would have on net income or loss. We are subject to fluctuations in foreign currency exchange rates when transactions are denominated in currencies other than the functional currencies. Such transactions were not material to our operations for the six month period ended June 30, 2015. Translation gains or losses, which are recorded in other comprehensive income or loss, result from translation of the assets and liabilities of our foreign subsidiaries into U.S. dollars. For the three month period ended June 30, 2015, foreign currency translation gains totaled approximately $3 million, and for the six month period ended June 30, 2015, foreign currency translation losses totaled approximately $19 million and related primarily to our Canadian operations. Our Canadian presence has grown in recent years due to acquisitions.

Our exposure to fluctuations in foreign currency exchange rates could increase in the future if we continue to expand our operations outside of the United States. We seek to manage foreign currency exposure by minimizing our consolidated net asset and liability positions in currencies other than the functional currency, neither of which were material as of June 30, 2015. We may enter into foreign currency derivative contracts in the future to manage such exposures.


Item 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In conducting the evaluation and in light of the Audit Committee independent investigation described in the 2014 Form 10-K, we identified the material weakness in our internal control over financial reporting within a service line in our Electrical Transmission segment described below. As a result, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2015.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Management determined that a material weakness in internal control over financial reporting existed within a service line in our Electrical Transmission segment due to the operational failure of the internal control process requiring adequate documentation of significant judgments made in determining cost-to-complete estimates under percentage-of-completion accounting. The review process failed to ensure that cost-to-complete estimates had sufficient supporting documentation. As a result, significant judgments were made and incorporated into the accounting records used to determine project revenue without sufficient documentation that clearly sets forth the rationale and factors used in making those judgments.

This material weakness resulted in the restatement of the Company’s first quarter 2014, second quarter 2014 and third quarter 2014 condensed unaudited consolidated financial statements.

Management’s Plans for Remediation of the Material Weakness

In response to this material weakness, the Company has developed a plan to remediate this material weakness. Currently, the plan to remediate includes the following:


•	The Company will revise its existing MasTec Revenue Recognition Policy (the “MasTec Policy”) with more detailed guidance on cost estimation procedures, project cost reserves and other aspects of percentage-of-completion accounting;


•	The MasTec Policy will require sufficient supporting documentation of significant judgments made in cost-to-complete estimates, including documentation of major assumptions, discussions and factors considered in making those decisions;


•	The Company has formalized and provided staffing to implement a procedure pursuant to which corporate personnel perform reviews of significant project variances and inspect documentation to determine that changes are in accordance with the MasTec Policy, have appropriate rationale and sufficient supporting documentation;


•	The Company established temporary remedial procedures in April 2015 and is evaluating the need for additional permanent remedial measures.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting other than identification of the material weakness identified above, along with related remediation efforts.

PART II. OTHER INFORMATION


ITEM 1.	LEGAL PROCEEDINGS

Legacy Litigation

Refer to Note 15 – Commitments and Contingencies in the notes to our condensed unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q, which is incorporated by reference in this Item 1, for a discussion of any recent material developments related to our legal proceedings since the filing of our 2014 Form 10-K.


ITEM 1A.	RISK FACTORS

Except as set forth below, there have been no material changes to either the cautionary statement regarding forward-looking statements or to any of the risk factors disclosed in our 2014 Form 10-K, as updated by our Quarterly Reports on Form 10-Q.

Risks Related to Our Business

We derive a significant portion of our revenue from a few customers and the loss of one or more of these customers, or a reduction in their demand for our services, could impair our financial performance.

For the six month period ended June 30, 2015, we derived approximately 18% and 13% of our revenue from AT&T and DIRECTV^®, respectively. For the six month period ended June 30, 2014, we derived approximately 24%, 13% and 11% of our revenue from AT&T, DIRECTV^®and Enbridge, Inc., respectively. Our ten largest customers accounted for approximately 57% and 69% of our revenue for the six month periods ended June 30, 2015 and 2014, respectively. In July 2015, AT&T acquired DIRECTV®. On a combined basis, AT&T and DIRECTV® represented 31% and 37% of our revenue for the six month periods ended June 30, 2015 and 2014, respectively. Taking into consideration the acquisition of DIRECTV® by AT&T, our top ten customers would have accounted for 59% and 70% of our revenue six month periods ended June 30, 2015 and 2014, respectively. Because our business is concentrated among relatively few major customers, and certain of our services are provided on a non-recurring, project by project basis, our results of operations, cash flows and liquidity could be negatively affected if these customers reduce the amount of business they provide to us, or if we complete the required work on our projects for these customers and cannot replace them with similar projects. More than half of our revenue for the six month period ended June 30, 2015 was derived from non-recurring project specific work. In addition, many of the contracts with our largest customers may be canceled on short or no advance notice. Any of these factors could negatively impact our results of operations, cash flows and liquidity.

Our operations in existing international markets, or expanding into additional international markets, may not be successful and could expose us to risks, including the failure to comply with the U.S. Foreign Corrupt Practices Act and other similar anti-bribery laws, which could harm our business and prospects.

We derived 16% of our revenue for the six months ended June 30, 2015 from international markets, and we may further expand the volume of international services we provide as well as the foreign geographic territories in which we operate. Our international operations are presently conducted primarily in Canada, Mexico and in other countries in Latin America, but we have performed work in various other foreign countries, and revenue derived from, or the number of countries in which we operate, could expand over the next few years. Economic conditions, including those resulting from wars, civil unrest, acts of terrorism and other conflicts, or volatility in the global markets may adversely affect our customers, their demand for our services and their ability to pay for our services. In addition, there are numerous risks inherent in conducting our business internationally, including, but not limited to, potential instability in international markets, changes in regulatory requirements applicable to international operations, foreign currency fluctuations, exchange controls and other limits on our ability to repatriate earnings, political, economic and social conditions in foreign countries and complex U.S. and foreign laws and treaties, including tax laws and the U.S. Foreign Corrupt Practices Act (the “FCPA”). These risks could restrict our ability to provide services to international customers or to operate our international business profitably, and our overall business and results of operations could be negatively affected by our foreign activities.

The FCPA and similar anti-bribery laws in other jurisdictions prohibit U.S.-based companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. We pursue opportunities in certain parts of the world that experience corruption to some degree, and, in certain circumstances, compliance with anti-bribery laws may conflict with local customs and practices. Our policies mandate compliance with these anti-bribery laws. Further, we require our subcontractors, agents and others who work for us or on our behalf to comply with the FCPA and other anti-bribery laws. Although we have policies and procedures designed to ensure that we, our employees and our agents comply with the FCPA and other anti-bribery laws, there is no assurance that such policies or procedures will protect us against liability under the FCPA or other laws for actions taken by our agents, employees and intermediaries. If we are found to be liable for FCPA violations (either due to our own acts or our inadvertence, or due to the acts or inadvertence of others), we could incur severe criminal or civil penalties or other sanctions, which could have a material adverse effect on our reputation, business, results of operations or cash flows. In addition, detecting, investigating, and resolving actual or alleged FCPA violations is expensive and can consume significant time and attention of our senior management.
