MASTEC, INC.
NOTES TO THE 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 energy, utility and communications infrastructure, such as: electrical utility transmission and distribution; natural gas and petroleum pipeline infrastructure; wireless, wireline and satellite communications; power generation, including renewable energy infrastructure; and industrial infrastructure. MasTec’s customers are primarily in these industries.
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 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, 2012 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, 2012 contained in the Company’s most recent Annual Report on 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. 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.
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 shareholders’ equity. Net income or loss attributable to non-controlling interests is reported as a separate line item below net income. The Company’s investments in entities in which the Company does not have a controlling interest, but has the ability to exert significant influence, are accounted for using the equity method of accounting. Equity method investments are recorded as long-term assets in the condensed unaudited consolidated balance sheets. Income or loss from these investments is recorded within other income or expense, net, in the condensed unaudited consolidated statements of operations. The cost method is used for investments in entities over which the Company does not have the ability to exert significant influence. All significant intercompany balances and transactions have been eliminated in consolidation.
Management Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Key estimates include: the recognition of revenue, in particular, on long-term construction contracts, including estimates of costs to complete projects and provisions for contract losses; allowances for doubtful accounts; accrued self-insured claims; estimated fair values of goodwill and intangible assets, acquisition-related contingent consideration, assets and liabilities classified as held-for-sale, convertible debt obligations, available for sale securities and investments in cost and equity method investees; asset lives used in computing depreciation and amortization, including amortization of intangible assets; 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 may be material to the condensed unaudited consolidated financial statements.
Reclassifications
Certain prior year amounts have been reclassified to conform to the current period presentation.
Significant Accounting Policies
Except for adoption of the accounting pronouncements discussed below, there have been no material changes to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

New accounting pronouncements
Recently Issued Accounting Standards, Not Adopted as of June 30, 2013
In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-05, Foreign Currency Matters (Topic 830): Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-05”).  The objective of ASU 2013-05 is to resolve diversity in practice regarding the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. ASU 2013-05 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013. The Company is currently evaluating the potential impact of this ASU on its condensed unaudited consolidated financial statements.

In February 2013, the FASB issued ASU 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-04”). ASU 2013-04 provides guidance related to the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation.  ASU 2013-05 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2013. Retrospective application is required for all periods presented. The Company is currently evaluating the potential impact of this ASU on its condensed unaudited consolidated financial statements.    

In July 2013, the FASB issued ASU 2013-11, Liabilities (Topic 405): Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-11”).  ASU 2013-11 provides guidance on the presentation in the financial statements of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, and explains that unrecognized tax benefits should be presented as a reduction to deferred tax assets for net operating loss carryforwards, similar tax losses or tax credit carryforwards. To the extent a net operating loss carryforward, similar tax loss or tax credit carryforward is not available as of the reporting date under the tax law of the applicable jurisdiction, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists as of the reporting date. ASU 2013-11 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Retrospective application is permitted. The Company is currently evaluating the potential impact of this ASU on its condensed unaudited consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”).  The amendment requires disclosure of information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, disclosure is required, either on the face of the statement where net income is presented, or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The new requirements are effective for public companies in interim and annual reporting periods beginning after December 15, 2012. The adoption of ASU 2013-02 as of January 1, 2013 did not have an impact on the Company's condensed unaudited consolidated financial statements.

Note 2 – Earnings Per Share
Basic earnings per share is computed by dividing earnings available to MasTec’s common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by dividing earnings 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. The potential issuance of common shares upon the exercise, conversion or vesting, as applicable, of outstanding stock options and unvested restricted share awards, as calculated under the treasury stock method, as well as shares associated with the Company’s outstanding convertible debt securities, may be dilutive.

There were 123,077 and 61,878 weighted average anti-dilutive common stock equivalents from restricted share awards that were not included in the Company's diluted earnings per share calculations for the three and six month periods ended June 30, 2013, respectively. For the three and six month periods ended June 30, 2012, a total of 136,158 and 1,066 weighted average anti-dilutive common stock equivalents from restricted share awards, respectively, were not included in the Company’s diluted earnings per share calculations.
The Company’s Board of Directors authorized a $150 million share repurchase plan in 2011, under which the Company repurchased 4.6 million shares of common stock for $75.0 million during the year ended December 31, 2011. During the year ended December 31, 2012, the Company repurchased an additional 4.9 million shares under this plan for an aggregate purchase price of $75.0 million, which completed the share repurchase plan. The repurchased shares are held in the Company’s treasury. See Note 14 - Common Stock Activity.
Senior Convertible Notes – Diluted Share Impact
The Company has $215 million of outstanding convertible notes, including $105.3 million of new 4.0% senior convertible notes (the “New 4.0% Notes”) and $97.0 million of new 4.25% senior convertible notes (the “New 4.25% Notes” and, together with the New 4.0% Notes, the “New Convertible Notes”). The Company also holds $9.6 million of original 4.0% senior convertible notes and $3.0 million of original 4.25% senior convertible notes, (the “Original 4.0% Notes” and the “Original 4.25% Notes,” respectively and, collectively, the “Original Convertible Notes”). The New Convertible Notes have an optional physical (common share), cash or combination settlement feature and contain certain conditional conversion features. Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof plus accrued interest

Table of Contents

in cash, the conversion shares underlying the New Convertible Notes, totaling approximately 13.0 million shares if fully settled in common stock, are not included in the Company’s diluted share count. If, however, the Company’s average stock price per share exceeds the respective conversion prices for the New Convertible Notes during a given reporting period, the resulting weighted average value of the respective number of conversion shares underlying the New Convertible Notes in excess of the principal amount of the notes, converted to shares at the market price, is included in the Company’s diluted share count (such shares are referred to as “premium shares”). See below and Note 10 - Debt of the Company's consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2012.
The number of common shares issuable upon conversion of the Company’s Original Convertible Notes is determined for the corresponding periods by application of the “if-converted” method to the extent the effect on earnings per share from continuing operations is dilutive. Under the “if-converted” method, net income attributable to MasTec from continuing operations is adjusted to add back the after-tax amount of interest recognized in the period associated with the Original Convertible Notes, and correspondingly, the Original Convertible Notes are assumed to have been converted with the resulting common shares added to weighted average shares outstanding.
The following table summarizes the principal amounts of the Company’s outstanding convertible notes for the periods indicated, including their respective classification within the computation of earnings per share for the periods indicated (in millions):

Note 3 – Acquisitions and Other Investments
Allocations of purchase prices for acquisitions are based on estimates of the fair value of consideration paid and of the net assets acquired and are subject to adjustment upon finalization of these fair value estimates. In the second quarter of 2013 and in December 2012, the Company acquired certain businesses, as discussed below and in Note 3 - Acquisitions and Other Investments of the Company's consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2012. As of June 30, 2013, the allocations of purchase prices to the fair values of tangible and intangible assets and liabilities, including the estimated values of contingent earn-out obligations and the estimated useful lives of acquired assets for these acquisitions, are provisional and remain preliminary as 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 of the acquired businesses, as prescribed in the corresponding purchase agreements.
During the three and six months ended June 30, 2013, the Company revised its preliminary allocations for certain of the 2012 acquisitions based on new information about the facts and circumstances existing as of the respective dates of such acquisitions, or, for purchase price adjustments, based on the final net assets and net working capital of the businesses acquired, as prescribed in the relevant purchase agreements. These adjustments resulted in the recognition of, or adjusted the fair values of, certain acquired assets and assumed liabilities, which resulted in the revision of comparative prior period financial information. Such measurement period adjustments are presented as if the adjustments had been taken into account as of the dates of the respective acquisitions. All changes that do not qualify as measurement period adjustments are included in current period earnings.
2013 Acquisitions
Big Country
Effective May 1, 2013, MasTec acquired all of the issued and outstanding interests of Big Country Energy Services, Inc. and its affiliated operating companies (collectively, "Big Country") for an aggregate purchase price composed of approximately $103.5 million in cash, a five year contingent earn-out, valued at $22.8 million as of the date of acquisition, and the assumption of $24.4 million in debt. The earn-out is equal to 25% of the excess, if any, of Big Country’s annual earnings before interest, taxes, depreciation and amortization, over certain thresholds set forth in the purchase agreement, payable annually in cash.

Big Country is a North American oil and gas pipeline and facility construction services company, headquartered in Calgary, Alberta, Canada.  Big Country also has construction offices in Alberta, British Columbia and Saskatchewan, as well as in Wyoming and North Dakota. Big Country's services include oil, natural gas and natural gas liquids gathering systems and pipeline construction; pipeline modification and replacement services; compressor and pumping station construction; and other related services supporting the oil and gas production, processing and transportation industries. Big Country is expected to significantly expand MasTec's ability to take advantage of the rapidly expanding opportunities anticipated for energy infrastructure work in North America in the coming years.

Table of Contents

Finite-lived intangible assets will be amortized in a manner consistent with the pattern in which the related benefits are expected to be consumed. The intangible asset related to Big Country's pre-qualifications with companies in the oil and gas industry has been assigned an indefinite life as the pre-qualifications do not 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 Big Country'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 Big Country and MasTec. As of the date of acquisition, the total amount of goodwill expected to be deductible for tax purposes was $4.1 million.

The fair value of the earn-out obligation 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. The range of potential undiscounted payments that MasTec could be required to make under the earn-out arrangement was estimated to be between $0.3 million and $55.3 million; however, there is no maximum earn-out payment amount.

Big Country is reported within the Company's oil and gas segment.

Other 2013 Acquisitions

Effective April 1, 2013, MasTec acquired all of the issued and outstanding interests of Data Cell Systems, Inc. ("Data Cell"). Data Cell was formerly a subcontractor to MasTec's wireless business and will provide self-perform communications tower construction, installation, maintenance and other services in support of telecommunications infrastructure construction in the Company's communications segment.

Unaudited Pro Forma Information - 2013 Acquisitions
The following unaudited supplemental pro forma results of operations include the results of operations of each of the companies acquired in 2013 as if each had been consolidated as of January 1, 2012 and have been provided for illustrative purposes only. These unaudited pro forma results of operations do 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 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 pro forma combined results of operations presented below for three and six month periods ended June 30, 2013 and 2012, respectively, have been prepared by adjusting the historical results of MasTec to include the historical results of the acquisitions described above as if they occurred on January 1, 2012. These unaudited pro forma combined historical results were then adjusted for an increase in amortization expense due to the incremental intangible assets recorded related to the acquisitions, a reduction in interest income resulting from the cash consideration paid and a reduction in interest expense relating to the repayment of acquired debt. The unaudited pro forma results of operations do not include any adjustments to eliminate the impact of acquisition related costs or any cost savings or other synergies that may result from these acquisitions. As noted above, the unaudited pro forma results of operations do not purport to be indicative of the actual results that would have been achieved by the combined company for the periods presented or that may be achieved by the combined company in the future.

Table of Contents

quarter of 2013, the Company remeasured the contingent consideration liability for EC Source Services LLC ("EC Source") using currently available facts and circumstances, including recent and expected future performance, which resulted in an increase in EC Source's expected future earn-out liability. EC Source is reported within the Company's electrical transmission segment. In addition, the contingent consideration liability for Optima Network Services, Inc. ("Optima") was remeasured and settled in full during the first quarter of 2013 as a result of an amendment to the Optima purchase agreement effective February 28, 2013. Optima is reported within the Company's communications segment. The adjustments to the EC Source and Optima earn-out liabilities were recorded within other expense and other income, respectively, during the six month period ended June 30, 2013.
Other Investments
Through a 60%-owned consolidated subsidiary, MasTec owns a 34% interest in a rock extraction business in Panama (for a net beneficial ownership interest of 20.4%). This investment, which is a component of the Company's discontinued Globetec operation, is accounted for under the equity method of accounting, and is reflected within long-term assets of discontinued operations in the condensed unaudited consolidated financial statements. MasTec has performed construction services for this investee. No revenues were recognized for the three and six months ended June 30, 2013. Revenues of approximately $0.4 million and $1.2 million are included within the Company's results from discontinued operations for the three and six month periods ended June 30, 2012, respectively. Receivables from this investee, which are reflected within assets held for sale in the condensed unaudited consolidated financial statements, were approximately $3.7 million as of both June 30, 2013 and December 31, 2012.
The Company has certain other cost and equity method investments. None of these investments was material individually or in the aggregate for any period presented. No impairment charges related to the Company's cost method investments nor the Company's equity method investments were recorded during the three or six month periods ended June 30, 2013 or 2012.

Note 4 – Discontinued Operations
DirectStar
In May 2012, Red Ventures exercised its option to acquire from the Company all of the issued and outstanding equity interests in DirectStar, which provides marketing and sales services on behalf of DIRECTV®.

Globetec
In September 2012, the Company's board of directors approved a plan of sale for its Globetec business. The decision to sell was made after evaluation of, among other things, short and long-term prospects of the Globetec operation. Accordingly, Globetec's projects and assets are reflected as assets and liabilities of discontinued operations in the condensed unaudited consolidated balance sheets for all periods presented, and Globetec's results of operations are presented as discontinued operations in the condensed unaudited consolidated statements of operations for all periods presented.
As of June 30, 2013, the carrying value of the subject net assets held-for-sale was $19.4 million. This amount is composed of total assets of $29.3 million and total liabilities of $9.9 million. During the third quarter of 2012, the Company recognized impairment charges of approximately $6.4 million pertaining to goodwill and intangible assets as well as approximately $6.3 million of estimated losses on disposal in connection with its decision to sell Globetec. During the quarter ended June 30, 2013, the Company recognized additional impairment charges of approximately $0.3 million related to Globetec. Estimated losses on disposal were based on an evaluation of, among other things, the expected cash flows from the operation of the projects of the Globetec business, as well as the estimated net realizable value of the assets to be sold.
Management's current discussions with a potential buyer include discussion of a potential sale price that considers the Company's view of the estimated fair value of the net assets that have been classified as held-for-sale as of June 30, 2013. The Company's estimates are subject to change in the future. If the Company is not able to sell these projects and assets at the current estimated selling price, the Company may incur additional losses in the future.
The following table is a summary of assets and liabilities associated with the Globetec operation as of the dates as indicated (in millions):

The Globetec business has trade receivables for certain “pay-when-paid” projects that provide for payment through March 2018. These receivables, which are included within assets of discontinued operations, have been recorded at their respective net present values, with the non-current portion recorded within long-term assets of discontinued operations. Imputed interest is reflected within the results of operations from discontinued operations. As of June 30, 2013 and December 31, 2012, $6.0 million and $6.3 million were outstanding, respectively. Of these amounts, approximately $4.0 million and $4.3 million are long-term as of June 30, 2013 and December 31, 2012, respectively.
Certain of Globetec's international subsidiaries obtained short-term financing by factoring their respective accounts receivable. The amounts of receivables sold during the periods ended June 30, 2013 and 2012, and the balances outstanding as of June 30, 2013 and December 31, 2012, were not material.

Note 6 – 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, cash surrender value of life insurance policies, auction rate securities, cost and equity method investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration 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:

16

Table of Contents

Level 1 - Quoted market prices in active markets for identical assets or liabilities.
Level 2 - Observable market based inputs or other observable inputs.
Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data. These values are generally determined using valuation models incorporating management’s estimates of market participant assumptions.

The following methods and assumptions were used to estimate the fair values of financial instruments:
Cash Surrender Value of Life Insurance Policies. Cash surrender values of life insurance policies are based on current cash surrender values as quoted by insurance carriers. Life insurance policies support the Company’s split dollar agreements and deferred compensation plan assets.
Auction Rate Securities.  The fair value of the Company’s auction rate securities was estimated by an independent valuation firm, Houlihan Capital Advisors, LLC, using a probability weighted discounted cash flow model. During the second quarter of 2013, the Company sold one of its auction rate securities, and the issuer of another of its auction rate securities redeemed the security at its par value. See Note 7 - Securities Available for Sale.
Deferred Compensation Plan Liabilities. Deferred compensation plan liabilities are based on employee deferrals, together with Company matching contributions, which are valued according to employee-directed investment options. The fair value of deferred compensation plan liabilities is based on quoted market prices of the employees' underlying investment selections.
Acquisition-Related Contingent Consideration Acquisition-related contingent consideration in the table above represents the estimated fair value of additional future earn-outs payable for acquisitions of businesses that closed after January 1, 2009, in accordance with U.S. GAAP. The fair value of such acquisition-related contingent consideration is based on management’s estimates and entity-specific assumptions and is evaluated on an on-going basis. See Note 3 - Acquisitions and Other Investments for details of recent acquisitions.
Debt. The estimated fair values of the Company’s 4.875% senior notes, 7.625% senior notes, New Convertible Notes and Original Convertible Notes, which are measured on a nonrecurring basis, are based on quoted market prices, a Level 1 input. During the first quarter of 2013, the Company repurchased and redeemed all of its outstanding 7.625% senior notes. See Note 2 - Earnings per Share and Note 10 - Debt for details regarding the Company's debt instruments, including the value of the premium over the principal amount of the New Convertible Notes.

Note 7 - Securities Available For Sale
As of June 30, 2013, the Company’s securities available for sale consisted of auction rate securities, which represent interests in pools of student loans guaranteed by the U.S. government under the Federal Family Education Loan Program. During the second quarter of 2013, the issuer of one of the Company's student loan auction rate securities redeemed its security at the security's par value of $2.6 million. Additionally, during the quarter ended June 30, 2013, the Company sold its structured finance security, which had a par value of $5.0 million and a cost basis of $1.7 million. This structured finance security, which was fully collateralized by investment grade credit-linked notes is composed of floating rate international bank notes, had an attached credit default swap under which the principal value of the security would be partially or fully forfeited at net default rates on the underlying corporate debt obligations ranging from 8% to 9%. As of December 31, 2012, the net default rate was estimated to be 6.22%.

The gross unrealized gain of $1.1 million, net, was comprised of $0.7 million of unrealized gains in other comprehensive income and a deferred tax liability of $0.4 million.
Management believes the temporary unrealized decline in estimated fair value associated with its remaining student loan auction rate securities is primarily attributable to the limited liquidity of these investments and overall market volatility. The Company expects to recover the remaining cost basis of its student loan auction rate securities, and does not intend to sell, or believe that it will more likely than not be required to sell its student loan auction rate securities before recovery of their cost basis, which may be at maturity.        
The fair values of the Company's auction rate securities were estimated by an independent valuation firm, Houlihan Capital Advisors, LLC, as of June 30, 2013 and December 31, 2012, using a probability weighted discounted cash flow model. The valuation of these securities is sensitive to market conditions and management’s judgment and can change significantly based on the assumptions used. The following tables set forth the fair values of the Company’s auction rate securities by type of security and underlying credit rating as of the dates indicated (in millions):

4.875% Senior Notes
On March 18, 2013, the Company issued $400 million of 4.875% senior notes due March 15, 2023 (the “4.875% Senior Notes”) in a registered public offering. The 4.875% Senior Notes bear interest at a rate of 4.875% per annum, payable on March 15 and September 15 of each year, commencing on September 15, 2013. 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.  The 4.875% Senior Notes, as well as the Company's senior convertible notes described below, are effectively junior to MasTec's secured debt, including the Company's credit facility, to the extent of the value of the assets securing that debt.  The 4.875% Senior Notes are guaranteed on an unsecured unsubordinated basis by MasTec's direct and indirect 100%-owned domestic subsidiaries that guarantee the Company's credit facility.
The Company has the option to redeem all or a portion of the 4.875% Senior Notes at any time on or after March 15, 2018 at the redemption prices set forth in the indenture that governs the 4.875% Senior Notes (the “4.875% Senior Notes Indenture”) plus accrued and unpaid interest, if any, to the redemption date. At any time prior to March 15, 2018, the Company may redeem all or a part of the 4.875% Senior Notes at a redemption price equal to 100% of the principal amount of 4.875% Senior Notes redeemed plus an applicable premium, as defined in the 4.875% Senior Notes Indenture, together with accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to March 15, 2016, the Company may redeem up to 35% of the principal amount of the 4.875% Senior Notes using the net cash proceeds of one or more sales of the Company's capital stock, as defined in the 4.875% Senior Notes Indenture, at a redemption price of 104.875% of the principal amount, plus accrued and unpaid interest to the redemption date.
The 4.875% Senior Notes Indenture, among other things, generally limits the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to (i) incur additional debt and issue preferred stock, (ii) create liens, (iii) pay dividends, acquire shares of capital stock, make payments on subordinated debt or make investments, (iv) place limitations on distributions from certain subsidiaries, (v) issue guarantees, (vi) issue or sell the capital stock of certain subsidiaries, (vii) sell assets, (viii) enter into transactions with affiliates and (ix) effect mergers. The 4.875% Senior Notes Indenture provides for customary events of default, as well as customary remedies upon an event of default, as defined in the 4.875% Senior Notes Indenture, including acceleration of repayment of outstanding amounts.
Approximately $7.6 million in financing costs were incurred in connection with the issuance of the 4.875% Senior Notes. These deferred financing costs are included in other long-term assets in the condensed unaudited consolidated financial statements and will be amortized over the term of the 4.875% Senior Notes using the effective interest method. The Company used a portion of the proceeds from the 4.875% Senior Notes offering to fund the repurchase and redemption of the Company's $150 million principal amount of 7.625% senior notes due 2017 (the “7.625% Senior Notes”), discussed below, and to repay the outstanding balance of the Company's credit facility. The remaining net proceeds were used for working capital and other general corporate purposes.

Repurchase and Redemption of 7.625% Senior Notes
On March 18, 2013, the Company repurchased approximately $121.1 million of its 7.625% Senior Notes in a tender offer at a price of 102.792% of the principal amount, which included an early tender payment of $30.00 per $1,000 principal amount of notes tendered. The holders of the tendered 7.625% Senior Notes also received accrued interest from the most recent interest payment date to, but not including, the date of repurchase. In addition, on March 29, 2013, the Company redeemed the remaining outstanding $28.9 million aggregate principal amount of the 7.625% Senior Notes in accordance with their terms at a price of 102.542% of the principal amount thereof plus accrued interest from the most recent interest payment date to, but not including, the date of redemption.

A debt extinguishment loss of $5.6 million was recognized during the first quarter of 2013 in connection with the repurchase and redemption of the 7.625% Senior Notes, including $4.1 million of early payment premiums and $1.5 million of unamortized deferred financing costs. This loss is separately disclosed within the condensed unaudited consolidated statements of operations.

Credit Facility    
As of June 30, 2013, the Company had outstanding revolving loans under its credit facility, referred to as the "Credit Facility," of $70.6 million, which accrued interest at a weighted average rate of approximately 3.04% per annum. As of December 31, 2012, the Company had outstanding revolving loans of $134.0 million, which accrued interest at a weighted average rate of approximately 3.95% per annum. Letters of credit of approximately $119.6 million and $120.8 million were outstanding under the Credit Facility as of June 30, 2013 and December 31, 2012, respectively. The remaining borrowing capacity under the Credit Facility of $409.8 million and $345.2 million as of June 30, 2013 and December 31, 2012, respectively, was available for revolving loans or up to $230.4 million and $229.2 million, respectively, of new letters of credit. Outstanding letters of credit mature at various dates and most have automatic renewal provisions, subject to prior notice of cancellation. As of June 30, 2013, interest on outstanding letters of credit accrued at either 1.125% or 2.25% per annum, based on the type of letter of credit issued. As of December 31, 2012, interest on outstanding letters of credit accrued at either 1% or 2% per annum. The unused facility fee was 0.40% and 0.35% as of June 30, 2013 and December 31, 2012, respectively.
Senior Convertible Notes
New Senior Convertible Notes. The Company has $105.3 million of New 4.0% Notes and $97.0 million of New 4.25% Notes. The principal balance of the New Convertible Notes was divided between the fair value of the debt component and the fair value of the common stock conversion feature of the notes, which resulted in a total debt discount of $17.4 million as of March 2011, when the New Convertible Notes were issued. The debt discount is being accreted to interest expense over the remaining terms of the New Convertible Notes, which will increase interest expense during the terms of the New Convertible Notes above their 4.0% and 4.25% cash interest rates to an effective interest rate of 6.73%.  As of June 30, 2013, the remaining period of amortization associated with the debt discount and related financing costs was approximately 1.2 years. The fair value of the common stock conversion feature is recorded as a component of shareholders’ equity.

Note 13 – Other Retirement Plans
Multi-Employer Pension Plans. Certain of MasTec’s subsidiaries contribute amounts to multi-employer pension and other multi-employer benefit plans and trusts. 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.

The Company's contributions to multi-employer pension plans have increased for the six months ended June 30, 2013 as a result of higher activity levels, primarily in its oil and gas business.

On November 15, 2011, the Company, along with other members of the Pipe Line Contractors Association (“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, as defined under the Pension Protection Act of 2006. In connection with this withdrawal, the Company has a liability of $6.0 million as of June 30, 2013. The Company withdrew from Central States in order to mitigate its liability in connection with the plan. The Company currently does not have plans to withdraw from any other multi-employer pension plan as of June 30, 2013.

Note 15 - Income Taxes
The Company’s consolidated tax rates on income from continuing operations for the three month periods ended June 30, 2013 and 2012 were 38.0% and 39.0%, respectively, and for the six month periods ended June 30, 2013 and 2012 were 38.4% and 39.3%, respectively. 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 impact of significant discrete items is separately recognized in the quarter(s) in which they occur.
Note 16 - Segments and Operations by Geographic Area     
Segment Discussion

MasTec presents its continuing operations under 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 and has been determined in accordance with the criteria in Accounting Standards Codification ("ASC") 280, Segment Reporting. All five reportable segments derive their revenues from the engineering, installation and maintenance of infrastructure, primarily in North America.

The Communications segment performs engineering, construction and maintenance of communications infrastructure primarily related to wireless and wireline communications and install-to-the-home, and to a lesser extent, infrastructure for electrical utilities. MasTec also performs 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 the energy and utility end markets and other end markets through the installation and construction of power plants, wind farms, solar farms, related electrical transmission infrastructure, ethanol facilities and various types of industrial infrastructure. The Other category primarily includes small business units that perform construction services for a variety of end markets in Mexico and elsewhere internationally.

The accounting policies of the reportable segments are the same as those described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies. Intersegment revenues and costs are accounted for as if the revenues were to third parties because these items are based on negotiated fees between the segments involved. All intercompany transactions and balances are eliminated in consolidation; eliminations between segments are included in the Eliminations reconciling column in the tables below. Intrasegment revenues and costs between entities are eliminated to arrive at the segment totals. The Corporate column includes amounts related to Corporate functions such as administrative costs, professional fees, and acquisition costs. Segment results include certain allocations of centralized costs such as general liability, medical and workers' compensation insurance and information technology costs. Income tax expense is managed by Corporate on a consolidated basis and is not allocated to the reportable segments.

Income from continuing operations before non-controlling interests 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 that helps investors understand the Company's financial results and assess its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and versus 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.

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

Note 17 - 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.
Legacy Litigation. MasTec is subject to litigation, some of which dates from the period 2001 through 2006.
 Outstanding Legacy Litigation
The labor union representing the workers of Sistemas e Instalaciones de Telecomunicacion S.A. (“Sintel”), a former MasTec subsidiary that was sold in 1998, filed a claim that initiated an investigative action with the Audiencia Nacional, a Spanish federal court, against Telefonica and dozens of other defendants including current and former officers and directors of MasTec and Sintel, relating to Sintel’s 2000 bankruptcy.
On June 17, 2013, MasTec, the workers and the prosecutor resolved the matter, resulting in the dismissal all of the charges and claims brought against MasTec and the MasTec defendants. The workers provided MasTec and MasTec defendants with a release and an acknowledgment that MasTec and MasTec defendants acted in good faith and did not cause Sintel's bankruptcy. On June 20, 2013, the Audiencia Nacional issued an order dismissing the charges and claims against MasTec and the MasTec defendants and finding another party guilty and liable of certain charges.
The Company resolved the matter in order to avoid significant legal fees and the potential liabilities resulting from the actions of other Spanish defendants for which MasTec may be financially responsible under a theory of subsidiary (or vicarious) liability, the uncertainty of a trial before a foreign tribunal such as the Audiencia Nacional and to eliminate management time devoted to this matter. MasTec recorded a pre-tax charge of $9.6 million in 2012 in connection with this matter and recorded and additional pre-tax charge of $2.8 million during the second quarter of 2013 in connection with its resolution.

Other Outstanding Litigation

SunLight Entities. In 2011, Power Partners MasTec, LLC., a MasTec, Inc. subsidiary (“Power Partners”), entered into engineering, procurement, and construction agreements (“Contracts”) 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”). The initial contract price of each of the Projects was, subject to adjustment, approximately as follows: Somerset ($29 million), Morris ($36 million) and Sussex ($26 million). The Projects were funded on a project finance basis, including the proceeds of municipal bonds issued by county improvement authorities.

Power Partners and the SunLight Entities have commenced three separate arbitration proceedings against each other to address various disputes that presently exist between the parties on the three Projects. The parties allege, among other things, breach of contract against each other. Power Partners has also filed municipal liens and construction liens for the work performed. The liens have been challenged, and the Company is currently appealing the trial court's adverse ruling to the New Jersey appellate court. Power Partners is vigorously pursuing its claims against the SunLight Entities and vigorously defending against claims by the SunLight Entities.
City of Marathon. During 2010 and 2011, pursuant to a written contract, the Company provided certain construction services for the City of Marathon in Marathon, Florida.  The Company completed those services in 2011, but at the end of 2011, the Company had still not been paid for all of the work performed on the project. The Company is seeking in excess of $6 million against the City of Marathon for breach of contract and against the City of Marathon’s engineers for professional negligence. The City of Marathon and the engineers filed answers denying liability and claiming that the Company breached the contract.  Discovery is ongoing. The Company will continue to vigorously pursue these claims.
Other Commitments and Contingencies
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 11 - Lease Obligations for additional details.
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. 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, 2013 and December 31, 2012, the Company had $119.6 million and $120.8 million, respectively, of letters of credit issued under its Credit Facility, of which $53.2 million pertained to certain of the Company's insurance carriers as of both June 30, 2013 and December 31, 2012. The Company is not aware of any material claims relating to outstanding letters of credit as of June 30, 2013 or December 31, 2012.
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 any expenses or outlays it incurs. As of June 30, 2013, the estimated cost to complete projects secured by the Company’s $1.4 billion in performance and payment bonds was $655.9 million. As of December 31, 2012, the estimated cost to complete projects secured by the Company’s $1.1 billion in performance and payment bonds was $284.5 million.
Self-Insurance. MasTec maintains insurance policies subject to per claim deductibles of $1 million for its workers’ compensation policy, $2 million for its general liability policy and $2 million for its automobile liability policy. The Company has excess umbrella coverage up to $100 million per claim and in the aggregate. As of June 30, 2013 and December 31, 2012, MasTec’s liability for unpaid claims and associated expenses, including incurred but not reported losses related to its workers compensation, general liability and automobile liability insurance policies, was $50.2 million and $48.1 million, respectively, of which $29.7 million and $28.5 million, respectively, was reflected within non-current other liabilities in the condensed unaudited consolidated financial statements.
MasTec also maintains an insurance policy with respect to employee group health claims, which is subject to annual per employee maximum losses of $0.4 million. MasTec’s liability for employee group claims as of June 30, 2013 and December 31, 2012 was $1.2 million and $1.1 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 in which the Company is self-insured. As of both June 30, 2013 and December 31, 2012, these letters of credit amounted to $53.2 million. In addition, cash collateral deposited with insurance carriers, which is included in other long-term assets in the consolidated balance sheets, amounted to $1.4 million and $2.0 million as of June 30, 2013 and December 31, 2012, respectively. Outstanding surety bonds related to workers’ compensation self-insurance programs amounted to $10.9 million and $9.0 million as of June 30, 2013 and December 31, 2012, respectively.
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 of 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 Pension Plans. Certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees. The 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 multi-employer pension plan contribution rates are determined annually and assessed on a “pay-as-you-go” basis based on union employee payrolls. The required amount of future contributions cannot be determined for future periods because the number of union employees employed at any given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. 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 ("ERISA"), 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 regarding employers who are contributors to multi-employer defined benefit plans, a plan’s termination, an employer’s voluntary withdrawal from, or the mass withdrawal of all 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. Furthermore, the Pension Protection Act of 2006 added new funding rules generally applicable to plan years beginning after 2007 for multi-employer plans that are classified as “endangered,” “seriously endangered,” or “critical” status. If plans in which the Company’s subsidiaries participate are in critical status, benefit reductions may apply and/or the Company could be required to make additional contributions if the plans are determined to be underfunded.
Based upon the information available to the Company from plan administrators as of June 30, 2013, several of the multi-employer pension plans in which the Company’s subsidiaries participate are underfunded. The Pension Protection Act requires that underfunded pension plans improve their funding ratios within prescribed intervals based on the level of their underfunding. In addition, if a multi-employer defined benefit plan fails to satisfy certain minimum funding requirements, the Internal Revenue Service may impose on the employers contributing to such plan a nondeductible excise tax of 5% on the amount of the accumulated funding deficiency. The Company’s subsidiaries have 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. As a result, the Company's required contributions to these plans could increase in the future. The amount of additional funds the Company may be obligated to contribute in the future cannot be estimated, as such amounts will be based on future levels of work that require the specific use of those union employees covered by these plans.
On November 15, 2011, the Company, along with other members of the Pipe Line Contractors Association (“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 of such liability as of the date of withdrawal. The Company began paying installments towards this withdrawal liability in 2013, of which $6.0 million was outstanding as of June 30, 2013. 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 made a demand on the Company for the sum of $10.8 million in withdrawal liability, which sum included 2011 contribution amounts. The Company is vigorously opposing this demand because it believes that it legally and effectively withdrew from Central States on November 15, 2011. If Central States were to prevail in its assertion that the Company, in fact, withdrew after that date, then the amount of the Company’s withdrawal liability would increase to approximately $10.8 million. In addition, if Central States 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 withdrew from the plan, there could be additional liability. The Company currently does not have plans to withdraw from any other multi-employer pension plan.
See Note 13 - Other Retirement Plans for additional details.
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, 2013 and December 31, 2012, the Company was not aware of any 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 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 any reserves for potential warranty claims as they have been immaterial.
Note 18 - Concentrations of Risk
The Company had approximately 370 customers as of June 30, 2013, which included some of the largest and most prominent companies in the communications and utilities industries.

Note 20 – Supplemental Guarantor Condensed Unaudited Consolidating Financial Information
The New Convertible Notes, Original Convertible Notes are, and, through March 29, 2013, the 7.625% Senior Notes were, fully and unconditionally guaranteed on an unsecured, unsubordinated, joint and several basis by certain of the Company's existing and future 100%-owned direct and indirect domestic subsidiaries that are each guarantors of the Company's Credit Facility or other outstanding indebtedness (the “Guarantor Subsidiaries”).  The 4.875% Senior Notes are guaranteed on an unsecured unsubordinated, joint and several basis by the Company's 100%-owned domestic subsidiaries that guarantee the Credit Facility. Certain subsidiaries included in the Company's Guarantor Subsidiaries, which are minor individually and in the aggregate, do not guarantee the 4.875% Senior Notes. The Company's subsidiaries organized outside of the U.S. and certain domestic subsidiaries (collectively, the “Non-Guarantor Subsidiaries”) do not guarantee any of these notes. The subsidiary guarantees are subject to release in certain customary circumstances including upon the sale of a majority of the capital stock or substantially all of the assets of the subsidiary guarantor; if the guarantee under our Credit Facility and other indebtedness is released or discharged (other than due to payment under such guarantee); or when the requirements for legal defeasance are satisfied or the obligations are discharged in accordance with the related indentures.

ITEM 2.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following is a discussion of our business, financial position and results of operations as of and for the three and six months ended June 30, 2013 and 2012. This discussion and analysis should be read in conjunction with the audited consolidated financial statements and accompanying notes contained in our Form 10-K for the year ended December 31, 2012.
Business Overview
We are a leading infrastructure construction company operating mainly throughout North America across a range of industries. Our primary activities include, but are not limited to, the engineering, building, installation, maintenance and upgrade of energy, utility and communications infrastructure, such as: electrical utility transmission and distribution; natural gas and petroleum pipeline infrastructure; wireless, wireline and satellite communications; power generation, including renewable energy infrastructure and industrial infrastructure. Our customers are primarily in these industries.
Including our predecessor companies, we have been in business for more than 80 years. We offer our services primarily under the MasTec service mark and, as of June 30, 2013, we had approximately 14,900 employees and 420 locations. We have been consistently ranked among the top specialty contractors by Engineering News-Record over the past five years.
We serve a diversified customer base, which includes some of the leading pipeline, communications, power generation and utility companies in North America. For the six months ended June 30, 2013, our top ten customers for our continuing operations were AT&T, DIRECTV®, Enbridge, Inc., DCP Midstream, Chesapeake Midstream Partners LP, Isolux Ingenieria USA LLC, PPL Corporation, TransCanada Corporation, Talisman Energy and CenturyLink. We have longstanding relationships and have developed strong alliances with many of our customers and we strive to maintain these customer relationships and our status as a preferred vendor. We often provide services under multi-year master service and other service agreements. Because our business is concentrated among relatively few major customers, our business could be negatively affected if the amount of business we obtain from these customers is reduced, or if we complete the required work on projects and cannot replace them with similar projects.
Revenue concentration information for significant customers, as a percent of total consolidated revenue from continuing operations, is as follows:

See discussion of reportable segments below.
Reportable Segments Overview
We present our continuing operations under 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 and has been determined in accordance with the criteria in ASC 280, Segment Reporting. All five reportable segments derive their revenues from the engineering, installation and maintenance of infrastructure, primarily in North America.

The Communications segment performs engineering, construction and maintenance of communications infrastructure primarily related -to wireless and wireline communications and install-to-the-home, and to a lesser extent, infrastructure for electrical utilities. We also 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 the energy and utility end markets and other end markets through the installation and construction of power plants, wind farms, solar farms, related electrical transmission infrastructure, ethanol facilities and various types of industrial infrastructure. The Other category primarily includes small business units that perform construction services for a variety of end markets in Mexico and elsewhere internationally.
Overview of Financial Results
Second quarter 2013 revenue of $977.6 million decreased by $11.3 million, or 1%, from prior year revenue of $988.9 million. Acquisitions since July 1, 2012 contributed $86.6 million, or 9%, of our second quarter revenues. Organic revenue decreased by $97.8 million, or 10%, driven primarily by power generation and industrial project activity, which decreased by $135.1 million, or 68.1% versus the same period in the prior year. The decrease in power generation and industrial project activity resulted from the delay in renewal of the federal production tax credit for qualified wind facilities. As discussed in our Form 10-K for the year ended December 31, 2012, the federal production tax credit for qualified wind facilities was not renewed until January 2013, which has negatively affected 2013 wind project activity and revenue. The reduction in organic revenue related to power generation and industrial projects was partially offset by organic revenue growth of $37.2 million, largely attributable to strong results from our communications and electrical transmission segments.
As a percentage of revenue, costs of revenue, excluding depreciation and amortization, decreased by 370 basis points, from 87.8% to 84.1%, driven primarily by improved margins in our oil and gas and communications segments. The improvement in costs of revenue, excluding depreciation and amortization, as a percentage of revenue was partially offset by an increase in depreciation and amortization expense and general and administrative expense, both of which increased in dollar terms and as a percentage of revenue. These increases resulted, in part, from recent acquisitions, as well as from increased levels of capital investment in our business. Our second quarter 2013 results were also affected by a legal settlement charge of $2.8 million in connection with the resolution of Sintel, a legacy litigation matter, stock-based compensation expense of $4.3 million and transaction costs of $0.9 million. See Note 17 – Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements for additional information.
Second quarter 2013 income from continuing operations was $35.5 million, or $0.42 cents per diluted share, which includes the after-tax effect of $1.7 million, or $0.02 cents per diluted share, associated with the legal settlement charge discussed above, as well as the after-tax effect of $2.6 million, or $0.03 cents per diluted share, for second quarter 2013 stock-based compensation expense. Excluding these charges, second quarter 2013 adjusted income from continuing operations and adjusted diluted earnings per share were $39.9 million and $0.47 cents per diluted share, respectively. Second quarter 2012 income from continuing operations and diluted earnings per share were $31.2 million, or $0.38 cents per share, respectively. Excluding stock-based compensation expense, second quarter 2012 adjusted income from continuing operations and adjusted diluted earnings per share were $31.9 million and $0.39 cents per diluted share, respectively. Adjusted second quarter income from continuing operations and adjusted diluted earnings per share increased by approximately $8.0 million and $0.08 cents per share, or approximately 25.2% and 21.7%, respectively, from 2012 to 2013. See "Adjusted Income From Continuing Operations and Adjusted Income From Continuing Operations Per Diluted Share," included in our non-U.S. GAAP financial measures discussion following "Comparison of Quarterly Results," below.
Economic, Industry and Market Factors
While we have seen a recent improvement in overall economic and market conditions, we closely monitor the effects that changes in these conditions may have on our customers. General economic 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. This influence, as well as the highly competitive nature of our industry, particularly when work is deferred, can, 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. Other market and industry factors, such as access to capital for customers in the industries we serve, changes to our customers' capital spending plans, changes in technology, tax and other incentives, renewable energy portfolio standards and new or changing regulatory requirements affecting the industries we serve, can affect demand for our services. Fluctuations in market prices for, or availability of, oil, gas and other fuel sources can also affect demand for

our pipeline and renewable energy construction 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.
Impact of Seasonality and Cyclical Nature of Business
Our revenues and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, project schedules and timing, particularly for large non-recurring projects and holidays. Typically, our revenues are lowest in the first quarter of the year because cold, snowy or wet conditions cause delays. Revenues in the second quarter are 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 budget before the end of the year, which generally has a positive impact on our revenues. However, the holiday season and inclement weather can cause delays, which can reduce revenues and increase costs on affected projects. Any quarter may be positively or negatively affected by out of the ordinary 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 revenues, which may adversely affect us in a given period, even if not in total. 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.

See discussion of reportable segments within our "Comparisons of Quarterly Results" section below.
More than half of our revenue is derived from projects performed under master service and other service agreements, which are generally multi-year agreements. Certain of our master service agreements are exclusive up to a specified dollar amount per work order for each defined geographic area, but do not obligate our customers to undertake any large infrastructure projects or other work with us. Work performed under master service and other service agreements is typically generated through work orders, each of which is performed for a fixed fee. Services provided under these agreements range from engineering, project management and installation work to maintenance and upgrade services. Master service and other service agreements are frequently awarded on a competitive bidding basis, although customers are sometimes willing to negotiate contract extensions beyond their original terms without re-bidding. Our master service and other service agreements have various terms, depending upon the nature of the services provided, and typically provide for termination on short or no advance notice.
The remainder of our work is generated pursuant to contracts for specific projects or jobs that may require the construction and installation of an entire infrastructure system or specified units within an infrastructure system. Revenues from fixed price contracts are recognized using the percentage-of-completion method, measured by the costs incurred to date as a percentage of the estimated total costs for each contract. Customers are billed with varying frequency, generally monthly or upon attaining specific milestones. Such contracts generally include retainage provisions under which 2% to 15% of the contract price is withheld from us until the work has been completed and accepted by the customer.
Revenues from continuing operations by type of contract for the periods indicated were as follows (in millions):

As shown in the table above, more than 40% of our 2013 revenues from continuing operations were from non-recurring, project specific work, which may experience greater variability than master service agreement work due to the need to replace the revenue as projects are completed. Additionally, 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.
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. Our backlog estimates include amounts under master service and other service agreements in addition to construction projects. 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 presents 18-month backlog for our continuing operations by reportable segment as of the periods indicated (in millions):

While our backlog estimates include amounts under master service and other service agreements, our customers are not contractually committed to purchase a minimum amount of services under these agreements, most of which can be canceled on short or no advance notice. There can be no assurance as to our customers’ requirements or that our estimates are accurate. In addition, timing of revenues 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 revenues 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 revenues and earnings.
Critical Accounting Policies and 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 consolidated financial statements requires us to make estimates and judgments that affect the amounts reported in our consolidated financial statements and the accompanying notes. On an on-going basis, we evaluate our estimates, such as: the recognition of revenue, including estimates of costs to complete projects and provisions for contract losses; allowances for doubtful accounts; accrued self-insured claims; estimated fair values of goodwill and intangible assets; asset lives used in computing depreciation and amortization, including amortization of intangible assets; estimated fair values of acquisition-related contingent consideration, assets and liabilities classified as held-for-sale, convertible debt obligations, available for sale securities, and investments in cost and equity method investees; estimates of reserves and accruals; income taxes and litigation and contingencies. 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. As management estimates, by their nature, involve judgment 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 materially incorrect. 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 and to our most recent Annual Report on Form 10-K for further information regarding our critical accounting policies and estimates.
Results of Operations
Comparisons of Quarterly Results
The following table reflects our consolidated results of operations in dollar and percentage of revenue terms for the periods indicated (dollar amounts in millions). Our consolidated results of operations are not necessarily comparable from period to period due to the impact of recent acquisitions and dispositions. See Note 3 - Acquisition and Other Investments and Note 4 – Discontinued Operations in the notes to the condensed unaudited consolidated financial statements.

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, 2013 Compared to Three Months Ended June 30, 2012
Revenue. Our revenue was $977.6 million for the three months ended June 30, 2013, as compared with $988.9 million for the three months ended June 30, 2012, representing a decrease of $11.3 million or 1%. We derived approximately $86.6 million, or 9%, of our second quarter revenue from businesses acquired since July 1, 2012. Organic revenue decreased by $97.8 million, or 10%, largely driven by power generation and industrial segment activity, which decreased by $135.1 million, or 68% versus the same period in the prior year. As discussed in our Annual Report on Form 10-K for the year ended December 31, 2012, the federal production tax credit for qualified wind facilities was not renewed until January 2013, which has negatively affected 2013 wind project activity and revenue. The decline in power generation and industrial segment revenue for the three months ended June 30, 2013 was largely offset by strong results in our communications, oil and gas and electrical transmission segments. Second quarter communications revenue increased by $64.8 million, including $15.2 million of revenues from acquisitions. Oil and gas segment revenues grew by $33.2 million in the second quarter of 2013 as compared to the 2012 period, which was an increase of approximately 13%. Acquisitions contributed approximately $71.3 million of this growth. Electrical transmission project activity increased by approximately $29.6 million, or 33%. Key customers driving growth in our communications, oil and gas and electrical transmission segments included AT&T, Enbridge, Inc., Enterprise Fleet Management, Isolux Ingenieria USA LLC and PPL Corporation.
Costs of revenue, excluding depreciation and amortization. Costs of revenue, excluding depreciation and amortization, totaled $822.7 million, or 84.1% of revenue for the three months ended June 30, 2013, compared to $868.5 million, or 87.8% of revenue, for the three months ended June 30, 2012, a $45.8 million, or 5.3%, decrease. Of this decrease, $9.5 million was attributable to the decrease in revenue, and $36.6 million was attributable to an improvement of 370 basis points in costs of revenue, excluding depreciation and amortization, as a percentage of revenue. Improved margins in our oil and gas and communications segments largely drove the second quarter basis point improvement. Our oil and gas segment has benefited from higher margin long-haul pipeline activities in 2013, as well as from improved contract pricing and project efficiencies. In the prior year, we incurred approximately $25.0 million of losses on two oil and gas pipeline projects. Second quarter 2013 project margins also improved in our communications segment, driven primarily by efficiencies on wireless projects. The improvements in oil and gas and communications segment margins were offset, in part, by lower margins in power generation and electrical transmission.
Depreciation and amortization. Depreciation and amortization was $33.6 million in 2013, or 3.4% of revenue, as compared with $21.8 million, or 2.2% of revenue, for the three months ended June 30, 2012, an increase of approximately $11.8 million, or 54.4%. The increase was driven by $7 million of higher organic business depreciation expense, as well as $6 million of 2012-2013 acquisition-related depreciation and amortization, offset in part by a decrease of $1.1 million in amortization expense from historical acquisitions. The increase in organic business depreciation expense is largely attributable to equipment purchases in our oil and gas segment, and, to a lesser extent, in our electrical transmission and communications segments. See Note 16 - Segments and Operations by Geographic Areas in the notes to the condensed unaudited consolidated financial statements for details of depreciation expense by reportable segment.
General and administrative expenses. General and administrative expenses were $51.9 million, or 5.3% of revenue, for the three months ended June 30, 2013 as compared with $38.4, or 3.9% of revenue, for the three months ended June 30, 2012, an increase of $13.5 million, or 35.2%. Acquisitions contributed approximately $6.0 million of incremental general and administrative costs. Organic growth in general and administrative expenses was $7.5 million, which includes $3.1 million of incremental stock-based compensation expense and $0.9 million of acquisition-related transaction costs, plus approximately $3.5 million resulting from higher labor, information technology and other administrative costs associated with growth in our business. Stock-based compensation expense increased in the second quarter of 2013 as compared with 2012 as a result of higher

levels of participation in our employee stock purchase program, as well as from the second quarter issuance of restricted share awards under a new equity incentive program for certain employees of our EC Source business. See Note 12 - Stock-Based Compensation and Other Employee Benefit Plans in the notes to the condensed unaudited consolidated financial statements. As a percentage of revenue, general and administrative costs increased by approximately 140 basis points.
Interest expense, net. Interest expense, net of interest income, was $11.8 million, or 1.2% of revenue, for the three months ended June 30, 2013, as compared with $9.5 million, or 1.0% of revenue, for the three months ended June 30, 2012, an increase of $2.4 million. The increase was attributable to $2.1 million of incremental interest expense on our outstanding senior notes. In March 2013, we issued $400 million aggregate principal amount of 4.875% senior notes and repurchased and redeemed $150 million aggregate principal amount of our 7.625% senior notes. See Note 10 - Debt in the notes to the condensed unaudited consolidated financial statements.
Other expense (income), net. Other expense, net, was $0.3 million for the three months ended June 30, 2013, as compared with other income, net of $0.4 million for the three months ended June 30, 2012, a variance of $0.7 million. Our second quarter 2013 results were negatively affected by a final legal settlement charge of $2.8 million in connection with the resolution of Sintel, a legacy litigation matter. This charge was partially offset by a gain of $0.7 million on the sale of our structured finance auction rate security. See Note 17 - Commitments and Contingencies and Note 7 - Securities Available For Sale in the notes to the condensed unaudited consolidated financial statements.
Income taxes. Income tax expense was $21.8 million for the three months ended June 30, 2013, as compared with $19.9 million for the three months ended June 30, 2012, representing an increase of $1.8 million. The increase is primarily attributable to higher income, partially offset by a lower effective tax rate. Our effective tax rate on income from continuing operations was 38.0% for the three months ended June 30, 2013 as compared with an effective tax rate of 39.0% in the prior year. The lower current year effective tax rate is principally attributable to an increase in foreign earnings.
Loss from discontinued operations. Loss from discontinued operations, net of tax, was $0.5 million for the three months ended June 30, 2013 as compared with $1.1 million in the prior year period, a reduction of $0.6 million. We sold our DirectStar business in June 2012. See Note 4 – Discontinued Operations in the notes to the condensed unaudited consolidated financial statements for additional details.
Six Months Ended June 30, 2013 Compared to Six Months Ended June 30, 2012
Revenue. Our revenue was $1.9 billion for the six months ended June 30, 2013, as compared with $1.7 billion for the six months ended June 30, 2012, representing an increase of $169.1 million or 9.8%. Of this increase, $129.6 million, or approximately 77%, was attributable to businesses acquired since July 1, 2012. The organic revenue increase of $39.5 million, or 2.3%, is net of the $163.5 million decrease in power generation and industrial segment revenue in the first half of 2013. The federal production tax credit for qualified wind facilities was not renewed until January 2013, which has negatively affected 2013 wind project activity and revenue. The decline in power generation and industrial segment revenue for the six months ended June 30, 2013 was offset by strong results in our communications, oil and gas, and electrical transmission segments. Oil and gas segment revenues grew by $184.3 million in the first half of 2013 as compared with 2012, an increase of approximately 42.7%. Acquisitions contributed approximately $108.8 million of this growth. First half communications revenue increased by $100.5 million, including $20.8 million of acquisition revenues. Electrical transmission segment activity increased by approximately $49.8 million, or 32%. Key customers driving growth included Enbridge, Inc., Isolux Ingenieria USA, DCP Midstream, PPL Corporation, AT&T and Enterprise Fleet Management.
Costs of revenue, excluding depreciation and amortization. Our costs of revenue, excluding depreciation and amortization, were $1.6 billion, or 85.1% of revenue for the six months ended June 30, 2013, compared to $1.5 billion for the six months ended June 30, 2012, or 88.1% of revenue, a $93.4 million, or 6.1%, increase. The dollar increase is attributable to approximately $143.9 million of volume driven costs, offset in part by $50.6 million of cost improvement resulting from a 300 basis point decrease in costs of revenue, excluding depreciation and amortization, as a percentage of revenue. The basis point improvement was driven primarily by improved margins in our oil and gas and communications segments. Our oil and gas segment has benefited from higher margin long-haul pipeline activities in 2013, as well as from improved contract pricing and project efficiencies. In the prior year, we incurred approximately $25.0 million of project losses on two oil and gas pipeline projects. First half 2013 project margins also improved in our communications segment, driven primarily by efficiencies on wireless projects. The improvements in oil and gas and communications segment margins were offset, in part, by lower current year margins in our power generation and electrical transmission segments.
Depreciation and amortization. Depreciation and amortization was $65.4 million for the six months ended June 30, 2013, or 3.4% of revenue, as compared with $42.5 million, or 2.5% of revenue, for the six months ended June 30, 2012, an increase of approximately $22.9 million, or 53.8%. The increase was driven by $16.0 million of higher organic business depreciation expense, as well as $9.1 million of 2012-2013 acquisition-related depreciation and amortization, offset in part by a decrease of $2.2 million in amortization expense from historical acquisitions. The increase in organic business depreciation expense is primarily attributable to equipment purchases in our oil and gas segment, and, to a lesser extent, in our electrical transmission and communications segments. See Note 16 - Segments and Operations by Geographic Areas in the notes to the condensed unaudited consolidated financial statements for details of depreciation expense by reportable segment.
General and administrative expenses. General and administrative expenses were $100.8 million, or 5.3% of revenue, for the six months ended June 30, 2013 as compared with $75.7 million, or 4.4% of revenue, for the six months ended June 30, 2012, an increase of $25.1 million, or 33.2%. Acquisitions contributed approximately $8.2 million of incremental general and administrative costs. Organic growth in general and administrative expenses of $16.9 million, included $1.3 million of incremental bad debt expense, $1.4 million of acquisition-related transaction costs and $4.4 million of incremental stock-based compensation expense, in addition to higher labor, information technology and other administrative costs associated with growth in our business. Stock-based compensation expense increased in the first half of 2013 as compared with the same period in the prior year as a result of higher levels of participation in our employee stock purchase program, as well as from the second quarter issuance of restricted share awards under a new equity incentive program for certain employees of our EC Source business. See Note 12 - Stock-

Table of Contents

Based Compensation and Other Employee Benefit Plans in the notes to the condensed unaudited consolidated financial statements. As a percentage of revenue, general and administrative costs increased by approximately 90 basis points.
Interest expense, net. Interest expense, net of interest income, was $21.9 million, or 1.2% of revenue, for the six months ended June 30, 2013, as compared with $18.4 million, or 1.1% of revenue, for the six months ended June 30, 2012, an increase of $3.4 million. The increase is primarily attributable to $2.4 million of incremental interest expense on our outstanding senior notes. In March 2013, we issued $400 million aggregate principal amount of 4.875% senior notes and repurchased and redeemed $150 million aggregate principal amount of our 7.625% senior notes. Additionally, higher average outstanding balances on equipment notes payable and capital lease obligations contributed $0.7 million of incremental interest expense in the first half of 2013. See Note 10 - Debt in the notes to the condensed unaudited consolidated financial statements.
Loss on extinguishment of debt. We incurred a loss on debt extinguishment of $5.6 million in the first quarter of 2013 in connection with the repurchase and redemption of $150 million aggregate principal amount of our 7.625% senior notes. This amount is composed of $4.1 million of early payment premiums and $1.5 million of unamortized deferred financing costs. This loss is separately disclosed within the condensed unaudited consolidated statements of operations.
Other expense (income), net. Other income, net, was $0.6 million for the six months ended June 30, 2013, as compared with $0.9 million for the six months ended June 30, 2012. During the six months ended June 30, 2013, we recorded a final legal settlement charge of $2.8 million in connection with the resolution of Sintel, a legacy litigation matter. This charge was partially offset by a gain of $0.7 million on the sale of our structured finance auction rate security. See Note 17 - Commitments and Contingencies and Note 7 - Securities Available For Sale in the notes to the condensed unaudited consolidated financial statements.
Income taxes. Income tax expense was $34.1 million for the six months ended June 30, 2013, as compared with $27.8 million for the six months ended June 30, 2012, representing an increase of $6.4 million. The increase is primarily attributable to higher income, partially offset by a lower effective tax rate. Our effective tax rate on income from continuing operations was 38.4% for the six months ended June 30, 2013 as compared with an effective tax rate of 39.3% in the prior year. The lower current year effective tax rate is principally attributable to an increase in foreign earnings.
(Loss) income from discontinued operations. Loss from discontinued operations, net of tax, was $1.4 million for the six months ended June 30, 2013 as compared with $1.4 million of income from discontinued operations in the prior year period, a variance of $2.8 million, driven primarily by lower revenues and income in the first half of 2013 as compared with 2012 due to the sale of the DirectStar business in June 2012. See Note 4 – Discontinued Operations in the notes to the condensed unaudited consolidated financial statements.

Three Months Ended June 30, 2013 Compared to Three Months Ended June 30, 2012 - Segments
Communications

Revenue. Communications revenue was $496.6 million for the three months ended June 30, 2013, compared to $431.9 million for the three months ended June 30, 2012, an increase of $64.8 million, or 15.0%. Acquisitions contributed $15.2 million of the increase in revenue. Communications revenue was favorably affected by demand for our wireless services, which increased by $68.5 million, offset in part by lower demand for certain utility services. Key customers driving wireless growth included AT&T, Samsung and Ericsson. Utility revenues within our Communications segment decreased, driven primarily by a reduction of $10.9 million associated with natural gas transmission and distribution project work.

EBITDA. EBITDA for our Communications segment was $63.4 million, or 12.8% of revenue, for the three months ended June 30, 2013, compared to $47.0 million, or 10.9% of revenue in 2012, a $16.4 million, or 34.8% increase. Higher revenues contributed approximately $8.3 million of incremental EBITDA. As a percentage of revenue, EBITDA increased approximately 190 basis points, or approximately $8.2 million, as a result of improvements in contract pricing of wireless services, as well as better project efficiencies and utilization of resources.
  
Oil and Gas

Revenue. Oil and Gas revenue was $296.9 million for three months ended June 30, 2013, compared to $263.7 million for the three months ended June 30, 2012, representing an increase of $33.2 million, or 12.6%. Of this increase, $71.3 million was attributable to acquired businesses. Organic revenues decreased by approximately $38.2 million versus the prior year period, primarily due to timing of project completion and subsequent new project startup. Project activity in the second quarter of 2013 included large-diameter, long-haul pipeline projects, midstream pipeline projects and pipeline facilities projects. Long-haul activity increased by approximately $26.4 million, while midstream shale transmission and distribution activities increased by approximately $12.4 million. These increases were offset, in part, by a decrease in pipeline facility projects of approximately $7.2 million.

EBITDA. EBITDA for our Oil and Gas segment was $51.2 million for the three months ended June 30, 2013, or 17.2% of revenue, compared to $15.7 million for the three months ended June 30, 2012, or 6.0% of revenue, an increase of $35.5 million, or 226%. Higher revenues contributed approximately $6 million of incremental EBITDA. As a percentage of revenue, EBITDA improved by 1,120 basis points, or approximately $30 million. Second quarter EBITDA margins benefited from higher margin long-haul pipeline activities, as well as improved contract pricing and project efficiencies on ongoing project work. In the prior year, we incurred approximately $25.0 million of project losses on two oil and gas pipeline projects.

Electrical Transmission

Revenue. Electrical Transmission revenues were $118.6 million for the three months ended June 30, 2013, as compared to $88.9 million for the three months ended June 30, 2012, representing an increase of $29.6 million, or 33.3%, driven largely by transmission and substation projects with PPL Corporation and Isolux Ingenieria USA LLC. Transmission activities increased by approximately $26.8 million, while substation activities increased by approximately $2.8 million.
 
EBITDA. EBITDA for our Electrical Transmission segment was $11.5 million, or 9.7% of revenue for the three months ended June 30, 2013, compared to EBITDA of $12.1 million, or 13.6% of revenue for the three months ended June 30, 2012, a decrease of $0.6 million. The deterioration in EBITDA margins of 390 basis points, or approximately $3.5 million, was offset, in part, by $2.9 million of incremental EBITDA from higher revenues. The decrease in EBITDA margins was driven primarily by project startups and higher costs associated with certain projects.

Power Generation and Industrial

Revenue. Power Generation and Industrial revenues were $63.3 million for the three months ended June 30, 2013, compared to $198.3 million for the three months ended June 30, 2012, a decrease of $135.1 million, or 68.1%. The decrease in revenue was driven by a decline of $180.5 million in wind and solar project work, partially offset by an increase of $45.6 million in industrial and equipment project work. Delays in the renewal of production tax credits for qualified wind facilities, which were not renewed until January 2013, resulted in lower levels of wind activity in the first half of 2013.

EBITDA. EBITDA for our Power Generation and Industrial segment was negative $8.0 million for the three months ended June 30, 2013, compared to EBITDA of $13.4 million, or 6.8% of revenue for the three months ended June 30, 2012, a decrease of $21.4 million. The decrease in EBITDA is due to higher costs associated with certain projects, as well as the underutilization of operating and overhead capacity in 2013 due to the decrease in revenues. Despite the low levels of project activity in the first half of 2013, the Power Generation and Industrial segment maintained its general and administrative costs in anticipation of wind project growth in the second half of 2013 and in 2014 in light of the January 2013 renewal of the production tax credits. To be eligible for these tax credits, projects must be started in 2013.

Other

Revenue. Revenue from our Other segment was $3.4 million for three months ended June 30, 2013, compared to $6.2 million for the three months ended June 30, 2012, a decrease of $2.8 million, or 45%. This decrease resulted from completing a project in our international division to secure a fiber optic circuit and build a central office facility prior to the second quarter.

EBITDA. EBITDA from Other businesses was $0.4 million, or 10.5% of revenue, for the three months ended June 30, 2013, compared to $0.8 million of EBITDA for the three months ended June 30, 2012, a $0.4 million decrease. The decrease is primarily attributable to decreased revenues, as described above.
  
Eliminations

Revenue. Elimination balances represent the offset to intersegment revenues that have been reflected within each reportable segment's gross revenues. For the three months ended June 30, 2013, we had $1.2 million of intercompany revenue between our reportable segments compared to $0.1 million for the three months ended June 30, 2012.

Corporate

EBITDA. Certain of our corporate costs are not allocated to our reportable segments, including certain administrative costs, professional fees and acquisition costs. Corporate information technology costs are allocated to our reportable segments based on estimated usage. EBITDA for our Corporate segment was negative $15.8 million for the three months ended June 30, 2013, compared to negative EBITDA of $6.7 million for the three months ended June 30, 2012, a $9.0 million decrease. The variance is due, in part, to a $2.8 million final legal settlement charge in connection with Sintel, a legacy litigation matter. In addition, we incurred $3.1 million of incremental stock-based compensation expense as compared to the same period in the prior year. Other activity affecting Corporate EBITDA for the three months ended June 30, 2013 were acquisition-related transaction costs of $0.9 million and incremental bonus expense of $0.8 million. See Note 12 - Stock-Based Compensation and Other Employee Benefit Plans and Note 17 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements.

Six Months Ended June 30, 2013 Compared to Six Months Ended June 30, 2012 - Segments
Communications

Revenue. Communications revenue was $921.6 million for the six months ended June 30, 2013, compared to $821.0 million for the six months ended June 30, 2012, an increase of $100.5 million, or 12.2%. Acquisitions contributed $20.8 million of the increase in revenue. Communications revenue was favorably affected by demand for our wireless services, which increased by $109.7 million, offset in part by lower demand for certain utility services. Key customers driving wireless growth included AT&T, Samsung and Ericsson. Install-to-the-home project activities were up $9.4 million versus the prior year. Utility revenues within our Communications segment decreased, driven primarily by a reduction of $21.3 million associated with natural gas transmission and distribution project work.

EBITDA. EBITDA for our Communications segment was $109.8 million, or 11.9% of revenue, for the six months ended June 30, 2013, compared to $79.8 million, or 9.7% of revenue in 2012, a $30.0 million, or 37.5% increase. Higher revenues contributed approximately $12.0 million of incremental EBITDA. As a percentage of revenue, EBITDA increased approximately 220 basis points, or approximately $18.1 million, as a result of improvements in contract pricing of wireless services, as well as better project efficiencies and utilization of resources.
  
Oil and Gas

Revenue. Oil and Gas revenue was $615.7 million for the six months ended June 30, 2013, compared to $431.4 million for the six months ended June 30, 2012, representing an increase of $184.3 million, or 42.7%. Of this increase, $108.8 million, or approximately 59.0%, was attributable to acquired businesses. Organic revenues increased by approximately $75.5 million, and included projects for customers such as DCP Midstream, Chesapeake Midstream Partners LP and Pembina Pipeline Corporation. Project activity in the first half of 2013 included large-diameter, long-haul pipeline projects as well as midstream pipeline projects and pipeline facilities projects. Long-haul activity increased by approximately $132.2 million, while midstream shale and petroleum pipeline activities increased by approximately $81.0 million. These increases were offset, in part, by a decrease in pipeline facility projects of approximately $27.6 million.

EBITDA. EBITDA for our Oil and Gas segment was $93.6 million for the six months ended June 30, 2013, or 15.2% of revenue, compared to $28.3 million, or 6.6% of revenue, for the six months ended June 30, 2012, an increase of $65.3 million, or 230.5%. Higher revenues contributed approximately $28.0 million of incremental EBITDA. As a percentage of revenue, EBITDA improved by 860 basis points, or approximately $37.1 million. EBITDA margins for our Oil and Gas segment have benefited from higher margin long-haul pipeline activities, as well as improved contract pricing and project efficiencies on ongoing project work. In the prior year, we incurred approximately $25.0 million of project losses on two oil and gas pipeline projects.

Electrical Transmission

Revenue. Electrical Transmission revenues were $203.1 million for the six months ended June 30, 2013, as compared with $153.3 million for the six months ended June 30, 2012, representing an increase of $49.8 million, or 32.5%, driven largely by transmission and substation projects with Isolux Ingenieria USA LLC and PPL Corporation.

EBITDA. EBITDA for our Electrical Transmission segment was $14.9 million, or 7.3% of revenue for the six months ended June 30, 2013, compared to EBITDA of $20.5 million, or 13.4% of revenue for the six months ended June 30, 2012, a decrease of $5.6 million. The deterioration

47

Table of Contents

in EBITDA margins of 610 basis points, or approximately $9.4 million, was offset, in part, by $3.6 million of incremental EBITDA from higher revenues. The decrease in EBITDA margins was driven primarily by project startups and higher costs associated with certain projects.

Power Generation and Industrial

Revenue. Power Generation and Industrial revenues were $152.2 million for the six months ended June 30, 2013, compared to $315.7 million for the six months ended June 30, 2012, a decrease of $163.5 million, or 51.8%. The decrease in revenue was driven by a decline of $249.0 million in wind and solar project work, partially offset by an increase of $85.5 million in industrial and equipment project work. Delays in the renewal of production tax credits for qualified wind facilities, which were not renewed until January 2013, resulted in lower levels of wind activity in the first half of 2013.

EBITDA. EBITDA for our Power Generation and Industrial segment was negative $8.2 million for the six months ended June 30, 2013, compared to EBITDA of $18.4 million, or 5.8% of revenue for the six months ended June 30, 2012, a decrease of $26.5 million. The decrease in EBITDA is due to higher costs associated with certain projects, as well as the underutilization of operating and overhead capacity in 2013 due to the decrease in revenues. Despite the low levels of project activity in the first half of 2013, the Power Generation and Industrial segment has maintained its general and administrative costs in anticipation of wind project growth in the second half of 2013 and in 2014 in light of the January 2013 renewal of the production tax credits. To be eligible for these tax credits, projects must be started in 2013.

Other

Revenue. Revenue from Other businesses was $5.7 million for six months ended June 30, 2013, compared to $6.6 million for the six months ended June 30, 2012, a decrease of $0.9 million, or 13.4%. This decrease resulted from completing a project in our international division to secure a fiber optic circuit and build a central office facility.

EBITDA. EBITDA from Other businesses was $0.4 million, or 7.8% of revenue, for the six months ended June 30, 2013, compared to $0.6 million of EBITDA for the six months ended June 30, 2012, a decrease of $0.1 million. The decrease is primarily attributable to lower revenues, as described above.

Eliminations

Revenue. Elimination balances represent the offset to intersegment revenues that have been reflected within each reportable segment's gross revenues. For the six months ended June 30, 2013, we had $2.0 million of intercompany revenue between our reportable segments compared to $0.9 million for the six months ended June 30, 2012.

Corporate

EBITDA. Certain of our corporate costs are not allocated to our reportable segments, including certain administrative costs, professional fees and acquisition costs. Corporate information technology costs are allocated to our reportable segments based on estimated usage. EBITDA for our Corporate segment was negative $34.3 million for the six months ended June 30, 2013, compared to negative EBITDA of $16.1 million for the six months ended June 30, 2012, a $18.3 million decrease. The increase was due, in part, to a loss on debt extinguishment of $5.6 million that was incurred in connection with the repurchase and redemption of our 7.625% senior notes in March 2013. In addition, during the second quarter of 2013, we recorded a $2.8 million final legal settlement charge in connection with Sintel, a legacy litigation matter. We also incurred $4.4 million of incremental stock-based compensation expense in the first half of 2013 as compared with 2012. Other activity affecting Corporate EBITDA for the six months ended June 30, 2013 were acquisition-related transaction costs of $1.4 million. See Note 10 - Debt, Note 12 - Stock-Based Compensation and Other Employee Benefit Plans and Note 17 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements.

Non-U.S. GAAP Financial Measures
As appropriate, we supplement the reporting of our financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including income from continuing operations before non-controlling interests, before interest, income taxes, depreciation and amortization (“EBITDA”). In addition, we have presented “Adjusted EBITDA,” as well as adjusted income from continuing operations before non-controlling interests (“Adjusted Income From Continuing Operations”) and adjusted diluted earnings per share, continuing operations (“Adjusted Diluted Earnings From Continuing Operations Per Share”). All of these non-U.S GAAP measures exclude stock-based compensation expense, final Sintel legal settlement costs and the loss on debt extinguishment from the repurchase and redemption of our $150 million aggregate principal amount of 7.625% senior notes. See Note 12 - Stock-Based Compensation and Other Employee Benefit Plans, Note 17 - Commitments and Contingencies and Note 10 - Debt in the notes to the condensed unaudited consolidated financial statements.
We use EBITDA, Adjusted EBITDA, Adjusted Income From Continuing Operations and Adjusted Diluted Earnings From Continuing Operations Per Share to evaluate our performance, both internally and as compared with our peers, because it excludes 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. 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.

We believe these non-U.S. GAAP measures provide meaningful information that helps 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 or as a substitute for reported income from continuing operations before non-controlling interests, diluted earnings

per share, continuing operations, and net cash provided by operating activities. These non-U.S. GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our U.S. GAAP results and the provided reconciliations to the corresponding U.S. GAAP financial measures, provide a more complete understanding of our business. We strongly encourage investors and shareholders to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

The use of non-GAAP financial measures has certain limitations because they do not reflect all items of income and expense that affect our operations. We compensate for these limitations by reconciling the non-GAAP financial measures to the most comparable GAAP financial measures. These non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, measures prepared in accordance with GAAP and should not be considered measures of our liquidity. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore comparability may be limited. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.

EBITDA and Adjusted EBITDA should not be considered in isolation from, and are not intended to represent an alternative measure of, income from continuing operations before non-controlling interests or net cash provided by operating activities as determined in accordance with U.S. GAAP. The definitions of EBITDA and Adjusted EBITDA above are not the same as in our credit facility or in the indentures governing our notes; therefore, EBITDA and Adjusted EBITDA as presented in this discussion should not be used for purposes of determining our compliance with related covenants.

The following table reflects a reconciliation of EBITDA and Adjusted EBITDA to income from continuing operations before non-controlling interests, in dollar and percentage of revenue terms, for the periods indicated (dollar amounts in millions). The table below may contain slight summation differences due to rounding.

While EBITDA and Adjusted EBITDA are measures of the Company's ability to generate cash, these measures exclude the cash impact of changes in the Company's assets and liabilities as well as interest and income taxes. Net cash provided by operating activities in the condensed unaudited consolidated statement of cash flows takes these changes in the Company's assets and liabilities into account. The following table presents a reconciliation of EBITDA and Adjusted EBITDA to net cash provided by operating activities for total MasTec (in millions):

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

We present Adjusted Income From Continuing Operations and Adjusted Diluted Earnings From Continuing Operations Per Share. Management believes that Adjusted Income From Continuing Operations and Adjusted Diluted Earnings From Continuing Operations Per Share are important indicators of our operations because they exclude items that may not be indicative of, or are unrelated to, our core operating results, and provide a baseline for analyzing trends in our underlying business.  The following table presents Adjusted Income From Continuing Operations and Adjusted Diluted Earnings From Continuing Operations Per Share for the periods indicated:

(b)
Represents the after tax expense and corresponding diluted per share impact related to loss on debt extinguishment associated with the repurchase and redemption of our 7.625% senior notes in the first quarter of 2013. The tax effect was calculated using the effective tax rate from continuing operations for the respective period. See Note 10 - Debt in the notes to the condensed unaudited consolidated financial statements.
(c)
Represents the after tax expense and corresponding diluted per share impact related to the final Sintel legal settlement charge we recorded in the second quarter of 2013. The tax effect was calculated using the effective tax rate from continuing operations for the respective period. See Note 17 - Commitments and Contingencies in the notes to the condensed unaudited consolidated financial statements.
    
Financial Condition, Liquidity and Capital Resources
Our primary sources of liquidity are cash flows from continuing operations, availability under our credit facility, capital lease and other equipment financing arrangements 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 and debt service. We also evaluate opportunities for strategic acquisitions and/or investments from time to time that may require cash, and may consider opportunities to either repurchase, refinance or retire outstanding debt or repurchase outstanding shares of our common stock in the future.
Capital Expenditures. We estimate that we will spend approximately $120 million in 2013 on capital expenditures, and in addition, we expect to incur between $80 million and $100 million of equipment purchases under capital lease or other financing arrangements. For the six months ended June 30, 2013, we spent approximately $71 million on capital expenditures, and incurred approximately $80.0 million of equipment purchases under capital lease and other financing arrangements. Actual capital expenditures can 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. In addition, we expect to continue to sell older equipment as we upgrade to new equipment.
Earn-out Payments. In most of our recent acquisitions, we have agreed to pay earn-out payments to the sellers, generally based on 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, 2013 is approximately $167 million. Of this amount, $7.8 million represents the liability for earn-out obligations that have already been earned. The remainder, $159.1 million, is management's estimate of potential future earn-out obligations, both current and long-term, 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 months ended June 30, 2013 and 2012, we made cash payments of $7.8 million and $11.4 million, respectively, related to earn-out obligations. During the six months ended June 30, 2013 and 2012, we made cash payments of $12.8 million and $17.1 million, respectively, related to earn-out obligations. See Note 3 – Acquisitions and Other Investments in the notes to the condensed unaudited consolidated financial statements.
Income Taxes. Our cash tax payments increased to $41.6 million for the six months ended June 30, 2013 from $18.9 million for the six months ended June 30, 2012. Quarterly tax payments are based on estimates of full year activity and estimated tax rates. Our cash tax payments increased for the six months ended June 30, 2013 due primarily to the fact that we expect to have higher taxable income in 2013 from higher expected earnings.
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 and, we generally experience seasonal working capital needs from approximately April through October to support growth in accounts receivable, and to a lesser extent, inventory. Working capital needs tend to increase when we commence large amounts of work due to the fact that payroll and certain other costs, including inventory, are

52

Table of Contents

required to be paid before the receivables resulting from work performed are billed and collected. Timing of project close-outs can contribute to changes in unbilled revenue. Accounts receivable balances increased in the second quarter of 2013, from $877 million as of December 31, 2012 to $1.1 billion as of June 30, 2013 due to an increase in days sales outstanding, as discussed within the Summary of Financial Condition, Liquidity and Capital Resources below. Inventory balances decreased in the first half of 2013, from $84 million as of December 31, 2012 to $67 million as of June 30, 2013.
Our billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion (from 2% to 15%) of the contract amount until the job is completed. For certain customers, we maintain inventory to meet the material 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-when-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.
New Convertible Notes - Settlements. As of June 30, 2013, our common stock trading price was higher than the conversion prices of our New Convertible Notes. Currently, we intend to settle the principal amounts of our New Convertible Notes upon any conversion thereof in cash. As of June 30, 2013, we had outstanding $202.3 million aggregate principal amount of our New Convertible Notes. Notwithstanding our present intention to settle conversions of our New Convertible Notes in cash, we cannot assure you that we will be able to do so due to restrictions under our credit facility. As of June 30, 2013, these restrictions would not have limited our ability to settle the New Convertible Notes in cash. See Summary of Financial Condition, Liquidity and Capital Resources below for discussion pertaining to our credit facility.
Summary of Financial Condition, Liquidity and Capital Resources
There were no changes in general U.S. and global economic conditions since December 31, 2012 that have had a significant impact on our overall financial position, results of operations or cash flows for the six months ended June 30, 2013. Given the generally good credit quality of our customer base, we do not expect collection issues that would materially impact our liquidity in the next twelve months. In addition, as a result of our current capital structure, including our credit facility, we do not anticipate that current overall capital market conditions will materially impact our liquidity. 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, anticipated capital expenditures, insurance collateral requirements, earn-out obligations, letters of credit and debt service obligations for at least the next twelve months.
Sources and Uses of Cash
As of June 30, 2013, we had approximately $474 million in working capital, defined as current assets less current liabilities, compared to approximately $334 million as of December 31, 2012, an increase of $139 million. Total cash and cash equivalents of approximately $14 million as of June 30, 2013 decreased by $13 million from total cash and cash equivalents of $27 million as of December 31, 2012. Cash and cash equivalents from our continuing operations of $13 million as of June 30, 2013 decreased from approximately $26 million as of December 31, 2012.

Operating Activities. Cash flow from operations is primarily influenced by demand for our services, operating margins and the type of services we provide, but it can also be influenced by working capital needs, such as the timing of billings and collections of receivables and the settlement of payables and other obligations. A portion of working capital assets is typically converted to cash in the first quarter. Conversely, working capital needs generally increase from April through October due to the seasonality of our business. Cash provided by operating activities for the six months ended June 30, 2013 increased to $14.6 million from $4.2 million of cash used in operating activities for the same period in 2012, an increase of $18.8 million. The increase in cash provided by operating activities was principally driven by the impact of changes in non-cash adjustments of $39 million, primarily due to an increase in depreciation and amortization of $22.4 million and a $4.4 million increase in stock-based compensation. In addition, net income increased by $9.2 million, which was offset, in part, by the negative impact of net changes in assets and liabilities of $28 million. The net change in assets and liabilities is primarily related to use of working capital, as more fully described below.
Accounts receivable increased by $178.6 million during the six months ended June 30, 2013, as compared with an increase in accounts receivable of $246.0 million for the six months ended June 30, 2012, an improvement of $67.4 million. Billings in excess of earnings increased by $8.0 million during the six months ended June 30, 2013, as compared with a decrease in billings in excess of earnings of $9.9 million for the same period in the prior year, an improvement of $18.0 million. Inventories decreased by $17.1 million during the six months ended June 30, 2013, representing a source of cash, as compared with an increase in inventories of $7.7 million for the six months ended June 30, 2012, representing a use of cash, for a total improvement of $24.9 million. These changes were offset by changes in accounts payable and accrued expenses, which increased by $15 million for the six months ended June 30, 2013, as compared with an increase of $158 million in the prior year, for a net negative effect on working capital of $143.6 million.

Days sales outstanding for our continuing operations as of June 30, 2013 was 102, as adjusted for businesses acquired in the second quarter of 2013, as compared with days sales outstanding of 83 as of December 31, 2012, as adjusted for businesses acquired in December 2012. Days sales outstanding for our continuing operations, net of billings in excess of costs and earnings, and as adjusted for acquired businesses, was 90 as of June 30, 2013 and 71 as of December 31, 2012. The increase in days sales outstanding is largely attributable to timing of project billings and close-outs and temporary payment delays as a result of flooding in Calgary, Alberta, Canada at the end of the quarter. Changes in project and customer mix also contributed to the increase in days sales outstanding. We do not currently anticipate collection issues related to our outstanding accounts receivable balances, and we continue to actively bill and collect outstanding amounts in a timely manner.
Investing Activities. Net cash used in investing activities increased by $237.8 million to $180.9 million for the six months ended June 30, 2013 from $56.9 million of cash provided by investing activities for the six months ended June 30, 2012. The acquisitions of Big Country and DataCell in the second quarter of 2013 contributed $117.5 million of the increase. Also contributing to the increase in cash used in investing activities was the reduction in cash proceeds from the sale of our DirectStar business, which we sold in June of 2012 and received net cash proceeds of $97.7 million. Additionally, our capital expenditures have increased in 2013. We spent $71.4 million on capital expenditures for the six months ended June 30, 2013, an increase of $42.9 million as compared with the same period in the prior year. Capital expenditures have increased in 2013 to support higher activity levels in our oil and gas, electrical transmission and communications businesses. These increases were offset, in part, by $5.0 million of cash proceeds from the sale and redemption of two of our auction rate securities in the second quarter of 2013, and an increase in cash proceeds from sales of property and equipment of $15.2 million.
Financing Activities. Cash provided by financing activities for the six months ended June 30, 2013 was $153.4 million, as compared with cash used in financing activities of $56.1 million for the six months ended June 30, 2012, an increase of $209.5 million. The increase in cash provided by financing activities was driven principally by the proceeds from our issuance of $400 million aggregate principal amount of 4.875% Senior Notes in March 2013, partially offset by the repurchase and redemption of our $150 million aggregate principal amount of 7.625% Senior Notes. Additionally, net repayments of outstanding balances on our credit facility were $62.7 million higher in the six month ended June 30, 2013 as compared with 2012. Cash provided from financing activities for the six months ended June 30, 2013 also benefited from a decrease of $35.1 million in cash used for purchases of treasury stock.
Credit Facility
We have a $600 million senior secured revolving credit facility (the "Credit Facility") maturing on August 22, 2016. Up to $350 million of the Credit Facility is available for the issuance of letters of credit. Subject to certain terms in the Credit Facility, we have the option to increase our revolving commitments and/or establish term loans of up to $200 million in total. Borrowings under the Credit Facility will be used to refinance existing indebtedness and for working capital, capital expenditures and other corporate purposes, including the repurchase or prepayment of indebtedness; however, the Credit Facility restricts the repurchase or prepayment of certain unsecured indebtedness, including our senior notes due 2023 and senior convertible notes due 2014, unless we have at least $50 million of remaining liquidity (as defined in the Credit Facility) after any such repurchase or prepayment.
The Credit Facility requires that we maintain a consolidated leverage ratio (as defined in the Credit Facility) at or below 3.50 to 1.00 and a consolidated interest coverage ratio (as defined in the Credit Facility) at or above 3.00 to 1.00. Subject to customary exceptions, the Credit Facility also limits our ability to engage in certain activities, including acquisitions, mergers and consolidations, debt incurrence, investments, capital expenditures, asset sales, debt prepayments, lien incurrence and the making of distributions on or repurchases of capital stock.
Amounts borrowed under the Credit Facility will bear interest, at our option, at a rate equal to either (a) the eurocurrency rate (as defined in the Credit Facility), plus a margin of 1.50% to 2.50%, as determined based on our consolidated leverage ratio (as defined in the Credit Facility) as of the most recent fiscal quarter, or (b) the base rate, (which is equal to the highest of (i) the federal funds rate (as defined in the Credit Facility) plus 0.5%, (ii) Bank of America’s prime rate and (iii) the eurocurrency rate plus 1.00%, plus a margin of 0.50% to 1.50%, as determined based on our consolidated leverage ratio as of the most recent fiscal quarter. Financial standby letters of credit and commercial letters of credit issued under the Credit Facility are subject to a letter of credit fee of 1.50% to 2.50% and performance standby letters of credit are subject to a letter of credit fee of 0.75% to 1.25%, in each case based on our consolidated leverage ratio as of the most recent fiscal quarter. We must also pay a commitment fee to the lenders on any unused availability under the Credit Facility, which is equal to 0.25% to 0.45%, based on the Company’s consolidated leverage ratio as of the then most recent fiscal quarter.
As of June 30, 2013, we had $70.6 million outstanding revolving loans under our Credit Facility. Letters of credit of approximately $119.6 million were issued under our Credit Facility as of June 30, 2013. The remaining borrowing capacity under the Credit Facility of $409.8 million was available for revolving loans or up to $230.4 million of new letters of credit. Outstanding letters of credit mature at various dates and most have automatic renewal provisions, subject to prior notice of cancellation. As of June 30, 2013, interest on outstanding letters of credit accrued at either 1.125% or 2.250% per annum, based on the type of letter of credit issued, as described above. The unused facility fee was 0.40% as of June 30, 2013.
The Credit Facility is guaranteed by certain of our 100%-owned direct and indirect domestic subsidiaries, and it is collateralized by a first priority security interest in substantially all of our assets and the assets of our wholly owned subsidiaries and a pledge of the outstanding equity interests in certain of our operating subsidiaries. The Credit Facility also provides for customary events of default and carries cross-default provisions with our other significant debt instruments, including our indemnity agreement with our surety provider, as well as customary remedies upon an event of default (as defined in the Credit Facility), including the acceleration of repayment of outstanding amounts and other remedies with respect to the collateral securing the Credit Facility obligations.
Based upon current availability under our Credit Facility, our liquidity and our anticipated cash flow, 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.
Cash Overdrafts
On a daily basis, available funds are swept from our depository accounts into a concentration account and are used to repay debt under our Credit Facility. Cash overdrafts principally represent the balance of outstanding checks that have not yet cleared through the banking system. Other cash balances maintained by certain operating subsidiaries, which are not swept into our concentration account, as well as deposits made subsequent to the daily cash sweep, are classified as cash. We generally do not fund our disbursement accounts for checks we have written until the checks are presented to the bank for payment. Cash overdrafts are classified within accounts payable. There are no compensating balance requirements associated with our depository accounts and there are no other restrictions on the transfer of cash associated with our depository accounts. As of June 30, 2013, cash overdrafts totaled $23.0 million.
4.875% Senior Notes
On March 18, 2013, we issued $400 million of 4.875% senior notes due March 15, 2023 (the “4.875% Senior Notes”) in a registered public offering. The 4.875% Senior Notes bear interest at a rate of 4.875% per annum, payable on March 15 and September 15 of each year, commencing on September 15, 2013. 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.  The 4.875% Senior Notes, as well as our Senior Convertible Notes described below, are effectively junior to MasTec's secured debt, including our Credit Facility, to the extent of the value of the assets securing that debt. The 4.875% Senior Notes are guaranteed on an unsecured unsubordinated basis by MasTec's direct and indirect 100%-owned domestic subsidiaries that guarantee the Credit Facility.
We have the option to redeem all or a portion of the 4.875% Senior Notes at any time on or after March 15, 2018 at the redemption prices set forth in the indenture that governs the 4.875% Senior Notes (the “4.875% Senior Notes Indenture”) plus accrued and unpaid interest, if any, to the redemption date. At any time prior to March 15, 2018, we may redeem all or a part of the 4.875% Senior Notes at a redemption price equal to 100% of the principal amount of 4.875% Senior Notes redeemed plus an applicable premium, as defined in the 4.875% Senior Notes Indenture, as well as accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to March 15, 2016, we may redeem up to 35% of the principal amount of the 4.875% Senior Notes using the net cash proceeds of one or more sales of our capital stock, as defined in the 4.875% Senior Notes Indenture, at a redemption price of 104.875% of the principal amount, plus accrued and unpaid interest to the redemption date.
The 4.875% Senior Notes Indenture, among other things, generally limits the ability of MasTec and certain of its subsidiaries, subject to certain exceptions, to (i) incur additional debt and issue preferred stock, (ii) create liens, (iii) pay dividends, acquire shares of capital stock, make payments on subordinated debt or make investments, (iv) place limitations on distributions from certain subsidiaries, (v) issue guarantees, (vi) issue or sell the capital stock of certain subsidiaries, (vii) sell assets, (viii) enter into transactions with affiliates and (ix) effect mergers. The 4.875% Senior Notes Indenture provides for customary events of default, as well as customary remedies upon an event of default, as defined in the 4.875% Senior Notes Indenture, including acceleration of repayment of outstanding amounts.
Approximately $7.6 million in financing costs were incurred in connection with the issuance of the 4.875% Senior Notes. These deferred financing costs are included in other long-term assets in the condensed unaudited consolidated financial statements and will be amortized over the term of the 4.875% Senior Notes using the effective interest method. We used a portion of the proceeds from the 4.875% Senior Notes offering to fund the repurchase and redemption of our $150 million principal amount of 7.625% senior notes due 2017 (the “7.625% Senior Notes”), discussed below, and to repay the outstanding balance of the Credit Facility. The remaining net proceeds were used for working capital and other general corporate purposes.
Repurchase and Redemption of 7.625% Senior Notes
On March 18, 2013, we repurchased approximately $121.1 million of our 7.625% Senior Notes in a tender offer at a price of 102.792% of the principal amount, which included an early tender payment of $30.00 per $1,000 principal amount of notes tendered. The holders of the tendered 7.625% Senior Notes also received accrued interest from the most recent interest payment date to, but not including, the date of repurchase. In addition, on March 29, 2013, we redeemed the remaining outstanding $28.9 million aggregate principal amount of the 7.625% Senior Notes in accordance with their terms at a price of 102.542% of the principal amount thereof, plus accrued interest from the most recent interest payment date to, but not including, the date of redemption.

We recognized a debt extinguishment loss of $5.6 million during the first quarter of 2013 in connection with the repurchase and redemption of the 7.625% Senior Notes, including $4.1 million of early payment premiums and $1.5 million of unamortized deferred financing costs. This loss is separately disclosed within the condensed unaudited consolidated statements of operations.
Senior Convertible Notes
New Senior Convertible Notes. We have $105.3 million of new 4.0% senior convertible notes due 2014 (the "New 4.0% Notes”) and $97.0 million of new 4.25% senior convertible notes due 2014, (the “New 4.25% Notes” and, collectively with the New 4.0% Notes, the “New Convertible Notes”), both of which were issued in 2011, in exchange for identical principal amounts of original 4.0% senior convertible notes and original 4.25% senior convertible notes (the “Original 4.0% Notes” and “Original 4.25% Notes,” respectively, and collectively, the “Original Convertible Notes”). We paid exchange fees of approximately 50 basis points, or $1 million and incurred transaction costs of approximately $0.7 million in connection with the exchange. The terms of the New Convertible Notes are substantially identical to those of the Original Convertible Notes, except that the New Convertible Notes have an optional physical (share), cash or combination settlement feature and contain certain conditional conversion features.

Table of Contents

The New Convertible Notes are convertible at any time during the three months immediately preceding their respective maturity dates; prior to such time, however, the New Convertible Notes are convertible only under certain conditions. See discussion in Note 10 - Debt in the notes to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2012.
Because the New Convertible Notes have an optional cash settlement feature, and we intend to settle the principal amount of any conversions thereof in cash, the conversion shares underlying the principal amount of the New Convertible Notes totaling approximately 13.0 million shares are not included in our diluted share count. If, however, the average stock price per share exceeds the $15.76 conversion price for the New 4.0% Notes or the $15.48 conversion price for the New 4.25% Notes, then the resulting amount, in shares, of any premium will be included in our diluted share count (“premium shares”). Our average stock price exceeded the conversion prices of the New Convertible Notes for the three and six month periods ended June 30, 2013 and 2012. This resulted in the inclusion of 6.2 million and 6.1 million weighted average premium shares in our diluted share count for the three and six month periods ended June 30, 2013, respectively and 0.6 million and 1.2 million weighted average premium shares for the three and six month periods ended June 30, 2012. The value of the premium over the principal amount for the New Convertible Notes for the three and six month periods ended June 30, 2013 totaled approximately $187.9 million and $178.8 million, respectively. The value of the premium over the principal amount for the New Convertible Notes for the three and six month periods ended June 30, 2012 totaled approximately $10.0 million and $19.9 million, respectively. See Note 2 – Earnings Per Share and Note 10 – Debt in the notes to the condensed unaudited consolidated financial statements. The number of premium shares included in our diluted share count will vary with fluctuations in our share price. Higher actual share prices result in a greater number of premium shares. Because the number of shares required to be included in our diluted share count will vary with changes in our actual share price, we cannot predict the dilutive impact of any such premium shares in future periods.
Notwithstanding our present intention to settle conversions of our New Convertible Notes in cash, we cannot assure you that we will be able to do so due to restrictions under our Credit Facility, which restricts the repurchase or prepayment of certain unsecured indebtedness, including the Company’s senior notes due 2023 and senior convertible notes due 2014, unless the Company has at least $50 million of remaining liquidity (as defined in the Credit Facility) after any such repurchase or prepayment. If we were required to settle conversions of our New Convertible Notes in accordance with our stated intent to settle principal amounts due in cash, and we were unable to do so with existing cash balances or through our Credit Facility, we could be required to obtain additional funding or settle such conversions in shares of our common stock, which would be dilutive to our existing shareholders. We cannot be certain that such funding would be available on terms acceptable to us, or at all.
The New Convertible Notes are guaranteed by the Company’s direct and indirect 100%-owned subsidiaries that guarantee the Original Convertible Notes.
Original Senior Convertible Notes. In November 2009, we issued $100 million of Original 4.25% Notes due December 15, 2014 in a private placement. Of this amount, $97.0 million was canceled and exchanged in the first quarter of 2011 for a like principal amount of New 4.25% Notes in connection with our debt exchange as discussed above. The Original 4.25% Notes bear interest at a rate of 4.25% per year, payable semi-annually in arrears, on June 15 and December 15 of each year. On or prior to December 12, 2014, holders may convert their Original 4.25% Notes into shares of our common stock at an initial conversion rate of 64.6162 shares of our common stock per $1,000 principal amount of Original 4.25% Notes, which represents an initial conversion price of approximately $15.48 per share, subject to customary anti-dilution adjustment terms for these types of notes. Approximately $3.7 million in financing costs were incurred in connection with the issuance of the Original 4.25% Notes. These deferred financing costs are included in other assets in the condensed unaudited consolidated balance sheet and are being amortized over the term of the Original 4.25% Notes.
In June 2009, we issued $115 million of Original 4.0% Notes due June 15, 2014 in a registered offering. Of this amount, $105.3 million was canceled and exchanged in the first quarter of 2011 for a like principal amount of New 4.0% Notes in connection with our debt exchange as discussed above. The Original 4.0% Notes bear interest at a rate of 4.0% per year, payable semi-annually in arrears, on June 15 and December 15 of each year. On or prior to June 13, 2014, holders may convert their Original 4.0% Notes into shares of our common stock at an initial conversion rate of 63.4417 shares of our common stock per $1,000 principal amount of Original 4.0% Notes, which represents an initial conversion price of approximately $15.76 per share, subject to customary anti-dilution adjustment terms for these types of notes. Approximately $5.4 million in financing costs were incurred in connection with the issuance of the Original 4.0% Notes, which are included in other assets in the consolidated balance sheet and are being amortized over the term of the Original 4.0% Notes.
As of June 30, 2013, an aggregate principal amount of $12.6 million of Original Convertible Notes was outstanding.
The 4.25% and 4.0% senior convertible notes are guaranteed by certain of our 100%-owned direct and indirect domestic operating subsidiaries. There are no financial covenants on these notes; however, there are certain nonfinancial provisions and covenants associated with these notes.
Acquisition Debt
In connection with certain acquisitions, we have entered into or assumed certain debt and/or capital lease obligations. As of June 30, 2013, $32.3 million of this acquisition-related debt remained outstanding. As of June 30, 2013, we were in compliance with all provisions and covenants associated with our acquisition debt.
Debt Guarantees and Covenants
The New Convertible Notes and Original Convertible Notes are fully and unconditionally guaranteed on an unsecured, unsubordinated, joint and several basis by certain existing and future 100%-owned direct and indirect domestic subsidiaries that are guarantors of our Credit Facility or other outstanding indebtedness.  The 4.875% Senior Notes are guaranteed on an unsecured, unsubordinated joint and several basis by MasTec's 100%-owned direct and indirect domestic subsidiaries that guarantee the Credit Facility. See Note 20 - Supplemental Guarantor Condensed Unaudited Consolidating Financial Information in the notes to the condensed unaudited consolidated financial statements.

We were in compliance with all provisions and covenants pertaining to our outstanding debt instruments as of June 30, 2013.
Auction Rate Securities
Our securities available for sale consist of auction-rate securities, which represent interests in pools of student loans guaranteed by the U.S. government under the Federal Family Education Loan Program. During the second quarter of 2013, the issuer of one of the Company's student loan auction rate securities redeemed its security at the security's par value. Additionally, during the quarter ended June 30, 2013, the Company sold its remaining structured finance security. As of June 30, 2013, we held $10.3 million in par value of auction rate securities, with an estimated fair value and carrying value of $9.3 million. There were no adjustments to the cost basis of securities held as of June 30, 2013. See Note 7 – Securities Available for Sale in the notes to the condensed unaudited consolidated financial statements.
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 and liabilities associated with certain indemnification and guarantee arrangements. We do not have any material off-balance sheet financing arrangements with variable interest entities.
Leases. In the ordinary course of business, we enter into non-cancelable operating leases for certain of our facility, vehicle and equipment needs, including related party leases. These leases allow us to conserve cash and provide flexibility in that we pay a monthly rental fee for use of the related facilities, vehicles and equipment rather than purchasing them. The terms of these agreements vary from lease to lease, including some with renewal options and escalation clauses. We may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable for the remaining lease payments under the term of the lease. Rent expense related to operating leases, including short-term rentals, reflected within continuing operations, was approximately $50.6 million and $99.4 million for the three and six months ended June 30, 2013, respectively.
Letters of Credit. In the ordinary course of business, we are required to post letters of credit for our insurance carriers, surety bond providers and in support of performance under certain contracts. Such letters of credit are generally issued by a bank. 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, we 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, 2013, we had $119.6 million of letters of credit issued under our Credit Facility, of which $53.2 million pertained to certain of our insurance carriers. We are not aware of any material claims relating to outstanding letters of credit as of June 30, 2013 and do not believe it is likely that any material claims will be made under any of our outstanding letters of credit in the foreseeable future. We may be required to post additional letters of credit or other collateral in favor of our insurance carriers, surety bond providers or customers in the future. Posting letters of credit reduces our borrowing availability under our Credit Facility.
Performance and Payment Bonds. In the ordinary course of business, we are required by certain customers to provide performance and payment bonds for some of our contractual commitments related to projects in process. These bonds provide a guarantee to the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. If we fail 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. We must reimburse the surety for any expenses or outlays it incurs. As of June 30, 2013, the estimated cost to complete projects secured by our $1.4 billion in performance and payment bonds was $655.9 million. We believe it is unlikely that we will have to fund significant claims under performance and payment bonds in the foreseeable future. If our business continues to grow, our bonding requirements may increase in the future. If we are unable to successfully renew or obtain sufficient bonding capacity in the future, it could limit our ability to bid on certain contracts or perform work for certain customers.
Self-Insurance. We maintain insurance policies subject to per claim deductibles of $1 million for our workers’ compensation policy, $2 million for our general liability policy and $2 million for our automobile liability policy. We have excess umbrella coverage up to $100 million per claim and in the aggregate. Liabilities under these insurance programs are accrued based upon our estimate of the ultimate liability for claims reported and an estimate of claims incurred but not reported, with assistance from third-party actuaries. These insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties and the number of incidents not reported. Accruals are based upon known facts and historical trends and we believe such accruals to be adequate. As of June 30, 2013, our liability for unpaid claims and associated expenses, including incurred but not reported losses related to our workers compensation, general liability and automobile liability insurance policies, was $50.2 million, of which $29.7 million was reflected within non-current other liabilities in the condensed unaudited consolidated financial statements.
We also maintain an insurance policy with respect to employee group health claims, which is subject to annual per employee maximum losses of $0.4 million. Our liability for employee group claims as of June 30, 2013, which is based on statistical analysis of historical claims experience and specific knowledge of actual losses that have occurred, was $1.2 million.
We are required to post letters of credit and provide cash collateral to certain of our insurance carriers and to provide surety bonds in certain states in which we are self-insured. As of June 30, 2013, these letters of credit amounted to $53.2 million. In addition, cash collateral deposited with insurance carriers, which is included in other long term assets in the condensed unaudited consolidated balance sheets, amounted to $1.4 million as of June 30, 2013. Outstanding surety bonds related to workers' compensation self-insurance programs amounted to $10.9 million as of June 30, 2013.
Employment Agreements. We have 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 of control of the Company. Upon the occurrence of any of the defined events in the various employment agreements, we 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 Pension Plans. Certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees. The 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 multi-employer pension plan contribution rates are determined annually and assessed on a “pay-as-you-go” basis based on union employee payrolls. The required amount of future contributions cannot be determined for future periods because the number of union employees employed at any given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. 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 (“ERISA”), 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 regarding employers who are contributors to multi-employer defined benefit plans, a plan’s termination, an employer’s voluntary withdrawal from, or the mass withdrawal of all 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. Furthermore, the Pension Protection Act of 2006 added new funding rules generally applicable to plan years beginning after 2007 for multi-employer plans that are classified as “endangered,” “seriously endangered,” or “critical” status. If plans in which our subsidiaries participate are in critical status, benefit reductions may apply and/or we could be required to make additional contributions if the plans are determined to be underfunded.
Based upon the information available to us from plan administrators as of June 30, 2013, several of the multi-employer pension plans in which our subsidiaries participate are underfunded. The Pension Protection Act requires that underfunded pension plans improve their funding ratios within prescribed intervals based on the level of their underfunding. In addition, if a multi-employer defined benefit plan fails to satisfy certain minimum funding requirements, the Internal Revenue Service may impose on the employers contributing to such plan a nondeductible excise tax of 5% on the amount of the accumulated funding deficiency. We have been notified that certain plans to which our subsidiaries 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. As a result, we expect our required contributions to these plans to increase in the future. The amount of additional funds we may be obligated to contribute in the future cannot be estimated, as such amounts will be based on future levels of work that require the specific use of union employees covered by these plans.
On November 15, 2011, we, along with other members of the Pipe Line Contractors Association (“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 of such liability as of the date of withdrawal. We began paying installments towards this withdrawal liability in 2013, of which $6.0 million was outstanding as of June 30, 2013. We withdrew from Central States in order to mitigate our 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 made a demand on us for the sum of $10.8 million in withdrawal liability, which sum included 2011 contribution amounts. We are vigorously opposing this demand because we believe that we legally and effectively withdrew from Central States on November 15, 2011. If Central States were to prevail in its assertion that we, in fact, withdrew after that date, then the amount of our withdrawal liability would increase to approximately $10.8 million. In addition, if Central States 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 we withdrew from the plan, there could be additional liability. We currently do not have plans to withdraw from any other multi-employer pension plan.
Withdrawal liabilities, requirements to pay increased contributions and/or excise taxes in connection with any of the multi-employer pension plans in which our subsidiaries participate could negatively impact our liquidity and results of operations.
Indemnities. We generally indemnify our customers for the services we provide under our contracts, as well as other specified liabilities, which may subject us to indemnity claims, liabilities and related litigation. As of June 30, 2013, we were not aware of any material asserted or unasserted claims in connection with these indemnity obligations.
Other Guarantees. In the ordinary course of business, from time to time, we guarantee the obligations of our subsidiaries, including obligations under certain contracts with customers, certain lease obligations and in some states, obligations in connection with obtaining contractors’ licenses. We also generally warrant the work we perform for a one to two year period following substantial completion of a project. We have not historically accrued any reserves for potential warranty claims as they have been immaterial.
Impact of Inflation
The primary inflationary factors affecting our operations are labor and fuel costs, and to a lesser extent, material costs. The price of fuel is subject to unexpected fluctuations due to events outside of our control, including geopolitical events and fluctuations in global supply and demand. Significant fuel price increases could adversely impact our operating results in the future. 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
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 of 2.25%, or a base rate, as defined in the Credit Facility, plus a margin of 1.25%. As of June 30, 2013, we

had $70.6 million outstanding revolving loans under our Credit Facility. Interest on letters of credit issued under our Credit Facility currently accrues at either 1.125% or 2.25% per annum, based on the type of letter of credit issued. A 100 basis point increase in the interest rate applicable to revolving loans 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, 2013.
As of June 30, 2013, our fixed interest rate debt primarily included $400 million aggregate principal amount of 4.875% senior notes, $115 million aggregate principal amount of 4.0% senior convertible notes, $100 million aggregate principal amount of 4.25% senior convertible notes and $59.2 million of notes payable for equipment, which had a weighted average interest rate of approximately 3.1%. None of this debt subjects us to interest rate risk.
Foreign Currency Risk
We have foreign operations in Canada, as well as in parts of Latin America and the Caribbean. For the three and six month periods ended June 30, 2013, we had foreign currency translation losses of $6.0 million and $6.8 million, respectively, relating primarily to our Canadian operations, which were recorded as a component of other comprehensive income. If we continue to expand our operations outside of the United States, our exposure to fluctuations in foreign currency exchange rates could increase in the future.
Auction Rate Securities
Our securities available for sale consist of auction rate securities. Our auction rate securities represent interests in pools of student loans guaranteed by the U.S. government under the Federal Family Education Loan Program. During the second quarter of 2013, the issuer of one of the Company's student loan auction rate securities redeemed its security at the security's par value. Additionally, during the quarter ended June 30, 2013, the Company sold its remaining structured finance security. As of June 30, 2013, we held $10.3 million in par value of auction rate securities, which had an estimated fair value and carrying value of $9.3 million.
See Note 7 - Securities Available for Sale in the notes to the condensed unaudited consolidated financial statements.
Item 4.
CONTROLS AND PROCEDURES
As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of 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”). Based upon that evaluation, we concluded that as of June 30, 2013, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosures.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

LEGAL PROCEEDINGS
Legacy Litigation
Refer to Note 17 – 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 most recent Annual Report on Form 10-K.

ITEM 1A.
RISK FACTORS
Except as set forth below, there have been no material changes to any of the risk factors disclosed in our recently filed Annual Report on Form 10-K, as updated by our Quarterly Report on Form 10-Q for the three months ended March 31, 2013.
Risks Related to Our Business
We derive a significant portion of our revenue from a few customers, and the loss of one of these customers or a reduction in their demand for our services could impair our financial performance.

Table of Contents

For the six month period ended June 30, 2013, we derived approximately 20%, 15% and 10% of our revenue from continuing operations from AT&T, DIRECTV® and Enbridge, Inc., respectively. For the six month period ended June 30, 2012, we derived approximately 18% and 17% of our revenue from continuing operations from AT&T and DIRECTV®, respectively. In addition, our ten largest customers accounted for approximately 68% of our revenue from continuing operations for both of the six month periods ended June 30, 2013 and 2012. 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. A 40% of our revenue from continuing operations was derived from non-recurring project specific work for the six months ended June 30, 2013, which may further increase this risk if we are not able to replace completed project work with new 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.
