Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation – Dycom Industries, Inc. ("Dycom" or the "Company") is a leading provider of specialty contracting services throughout the United States and in Canada. These services include engineering, construction, maintenance and installation services to telecommunications providers, underground facility locating services to various utilities, including telecommunications providers, and other construction and maintenance services to electric and gas utilities and others. The consolidated financial statements include the results of Dycom and its subsidiaries, all of which are wholly-owned. All intercompany accounts and transactions have been eliminated and the financial statements reflect all adjustments, consisting of only normal recurring accruals that are, in the opinion of management, necessary for a fair presentation of such statements. These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). On December 3, 2012, the Company acquired substantially all of the telecommunications infrastructure service subsidiaries (the "Acquired Subsidiaries") of Quanta Services, Inc. Additionally, during the fourth quarter of fiscal 2013, the Company acquired Sage Telecommunications Corp of Colorado, LLC ("Sage") and certain assets of a tower construction and maintenance company. The results of operations of the businesses acquired are included in the accompanying consolidated financial statements from their respective dates of acquisition. Accounting Period – The Company uses a fiscal year ending on the last Saturday in July. Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported therein and accompanying notes. For the Company, key estimates include: recognition of revenue for costs and estimated earnings under the percentage of completion method of accounting, allowance for doubtful accounts, the fair value of reporting units for goodwill impairment analysis, the assessment of impairment of intangibles and other long-lived assets, the purchase price allocations of businesses acquired, accrued insurance claims, income taxes, asset lives used in computing depreciation and amortization, stock-based compensation expense for performance-based stock awards, and accruals for contingencies, including legal matters. At the time they are made, the Company believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole. However, actual results could differ from those estimates and such differences may be material to the financial statements. Revenue Recognition – The Company recognizes revenues under the percentage of completion method of accounting using the units-of-delivery or cost-to-cost measures. A majority of the Company’s contracts are based on units-of-delivery and revenue is recognized as each unit is completed. Revenues from contracts using the cost-to-cost measures of completion are recognized based on the ratio of contract costs incurred to date to total estimated contract costs. Revenues from services provided under time and materials based contracts are recognized when the services are performed. The current asset "Costs and estimated earnings in excess of billings" represents revenues recognized in excess of amounts billed. The current liability "Billings in excess of costs and estimated earnings" represents billings in excess of revenues recognized. Application of the percentage of completion method of accounting requires the use of estimates of costs to be incurred for the performance of the contract. The cost estimation process is based on the knowledge and experience of the Company’s project managers and financial professionals. Factors that the Company considers in estimating the work to be completed and ultimate contract recovery include the availability and productivity of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays in performance and the recoverability of any claims. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in changes to costs and income and their effects are recognized in the period in which the revisions are determined. At the time a loss on a contract becomes known, the entire amount of the estimated ultimate loss is accrued. Cash and Equivalents – Cash and equivalents primarily include balances on deposit in banks. The Company maintains substantially all of its cash and equivalents at financial institutions it believes to be of high credit quality. To date, the Company has not experienced any loss or lack of access to cash in its operating accounts. Restricted Cash – As of July 27, 2013 and July 28, 2012, the Company had approximately $3.7 million in restricted cash which is held as collateral in support of the Company's insurance obligations. Restricted cash is included in other current assets and other assets in the consolidated balance sheets and changes in restricted cash are reported in cash flows used in investing activities in the consolidated statements of cash flows. Allowance for Doubtful Accounts – The Company maintains an allowance for doubtful accounts for estimated losses resulting from the failure of its customers to make required payments. Management analyzes the collectability of accounts receivable balances each period. This analysis considers the aging of account balances, historical bad debt experience, changes in customer creditworthiness, current economic trends, customer payment activity and other relevant factors. Should any of these factors change, the estimates made by management may also change, which could affect the level of the Company’s future provision for doubtful accounts. Inventories – Inventories consist of materials and supplies used in the ordinary course of business and are carried at the lower of cost (using the first-in, first-out method) or market. Inventories also include certain job specific materials which are valued using the specific identification method. For contracts where the Company is required to supply part or all of the materials on behalf of the customer, the loss of the customer or declines in contract volumes could result in an impairment of the value of materials purchased. Property and Equipment – Property and equipment are stated at cost and depreciated on a straight-line basis over their estimated useful lives (see Note 6, Property and Equipment, for the range of useful lives). Amortization of capital lease assets is included in depreciation expense. Maintenance and repairs are expensed as incurred and major improvements are capitalized. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in other income. Capitalized software is accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standard Codification ("ASC") Topic 350-40, Internal Use Software. Capitalized software consists primarily of costs to purchase and develop internal-use software and is amortized over its useful life as a component of depreciation expense. Property and equipment includes internally developed capitalized computer software gross cost and net book value of $18.3 million and $11.6 million, respectively, as of July 27, 2013, and gross cost and net book value of $11.6 million and $7.4 million, respectively, as of July 28, 2012. Goodwill and Intangible Assets – The Company accounts for goodwill in accordance with ASC Topic 350, Intangibles-Goodwill and Other ("ASC Topic 350"). The Company's reporting units goodwill and other related indefinite-lived intangible assets are assessed annually as of the first day of the fourth fiscal quarter of each year in accordance with ASC Topic 350 in order to determine whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If the Company determines the fair value of goodwill or other indefinite-lived intangible assets is less than their carrying value as a result of the tests, an impairment loss is recognized. Impairment losses, if any, are reflected in operating income or loss in the consolidated statements of operations during the period incurred. In accordance with ASC Topic 360, Impairment or Disposal of Long-Lived Assets, the Company reviews finite-lived intangible assets for impairment whenever an event occurs or circumstances change which indicates that the carrying amount of such assets may not be fully recoverable. Recoverability is determined based on an estimate of undiscounted future cash flows resulting from the use of an asset and its eventual disposition. An impairment loss is measured by comparing the fair value of the asset to its carrying value. If the Company determines the fair value of an asset is less than the carrying value, an impairment loss is incurred. Impairment losses, if any, are reflected in operating income or loss in the consolidated statements of operations during the period incurred. The Company uses judgment in assessing if goodwill and intangible assets are impaired. Estimates of fair value are based on the Company's projection of revenues, operating costs, and cash flows taking into consideration historical and anticipated future results, general economic and market conditions, as well as the impact of planned business or operational strategies. To measure fair value, the Company employs a combination of present value techniques which reflect market factors. Changes in the Company's judgments and projections could result in significantly different estimates of fair value potentially resulting in additional impairments of goodwill and other intangible assets. Business Combinations – The Company accounts for business combinations under the acquisition method of accounting. The purchase price of each acquired business is allocated to the tangible and intangible assets acquired and the liabilities assumed on the basis of their respective fair values on the date of acquisition. Any excess of the purchase price over the fair value of the separately identifiable assets acquired and the liabilities assumed is allocated to goodwill. The valuation of assets acquired and liabilities assumed requires a number of judgments and is subject to revision as additional information about the fair value of assets and liabilities becomes available. Additional information, which existed as of the acquisition date but at that time was unknown to the Company, may become known during the remainder of the measurement period, a period not to exceed twelve months from the acquisition date. Adjustments in the purchase price allocation may require a recasting of the amounts allocated to goodwill and intangible assets. In accordance with the acquisition method of accounting, acquisition costs are expensed as incurred. Long-Lived Tangible Assets – The Company reviews long-lived tangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of an asset group and its eventual disposition. Measurement of an impairment loss is based on the fair value of the asset compared to its carrying value. Long-lived tangible assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. Accrued Insurance Claims – The Company retains the risk of loss, up to certain limits, for claims related to automobile liability, general liability, workers' compensation, employee group health, and locate damages. Locate damage claims result from property and other damages arising in connection with the Company's underground facility locating services. A liability for unpaid claims and the associated claim expenses, including incurred but not reported losses, is determined with the assistance of an actuary and reflected in the consolidated financial statements as accrued insurance claims. The liability for accrued claims and related accrued processing costs was $56.3 million and $48.8 million at July 27, 2013 and July 28, 2012, respectively, and included incurred but not reported losses of approximately $26.0 million and $22.3 million, respectively. Based on prior payment patterns for similar claims, the Company expects $29.1 million of the amount accrued at July 27, 2013 to be paid within the next twelve months. The Company estimates the liability for claims based on facts, circumstances and historical evidence. When loss reserves are recorded they are not discounted, even though they will not be paid until sometime in the future. Factors affecting the determination of the expected cost for existing and incurred but not reported claims include, but are not limited to, the estimated number of future claims, the payment pattern of claims which have been incurred, changes in the medical condition of claimants, and other factors such as inflation, tort reform or other legislative changes, unfavorable jury decisions and court interpretations. Income Taxes – The Company accounts for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event the Company determines that it would be able to realize its deferred income tax assets in the future in excess of their net recorded amount, it would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. ASC Topic 740, Income Taxes ("ASC Topic 740") prescribes a two-step process for the financial statement recognition and measurement of income tax positions taken or expected to be taken in an income tax return. The first step evaluates an income tax position in order to determine whether it is more likely than not that the position will be sustained upon examination, based on the technical merits of the position. The second step measures the benefit to be recognized in the financial statements for those income tax positions that meet the more likely than not recognition threshold. ASC Topic 740 also provides guidance on derecognition, classification, recognition and classification of interest and penalties, accounting in interim periods, disclosure and transition. Under ASC Topic 740, companies may recognize a previously unrecognized tax benefit if the tax position is effectively (as opposed to "ultimately") settled through examination, negotiation or litigation. Per Share Data – Basic earnings per common share is computed based on the weighted average number of shares outstanding during the period, excluding unvested restricted share units. Diluted earnings per common share includes the weighted average common shares outstanding for the period and dilutive potential common shares, including unvested restricted share units. Performance vesting restricted share units are only included in diluted earnings per common share calculations for the period if all the necessary performance conditions are satisfied and their impact is dilutive. Common stock equivalents related to stock options are excluded from diluted earnings per common share calculations if their effect would be anti-dilutive. Stock-Based Compensation – The Company's stock-based award programs are intended to attract, retain and reward talented employees, officers and directors, and to align stockholder and employee interests. Stock-based awards are granted by the Company under its 2012 Long-Term Incentive Plan ("2012 Plan"), 2003 Long-Term Incentive Plan ("2003 Plan"), and the 2007 Non-Employee Directors Equity Plan ("2007 Directors Plan" and, together with the 2012 Plan and 2003 Plan, the "Plans"). The Company also has several other plans, both expired and current, under which awards are outstanding but under which no further awards will be granted. The Company's policy is to issue new shares to satisfy equity awards under the Plans. The Plans provide for the grants of a number of types of stock-based awards, including stock options, restricted shares, performance shares, restricted share units, performance share units ("Performance RSUs"), and stock appreciation rights. The total number of shares available for grant under the Plans as of July 27, 2013 was 2,033,272. Compensation expense for stock-based awards is based on the fair value at the measurement date and is included in general and administrative expenses in the consolidated statements of operations. The fair value of stock option grants is estimated on the date of grant using the Black-Scholes option pricing model based on certain assumptions including: expected volatility based on the historical price of the Company's stock over the expected life of the option; the risk free rate of return based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option; the expected life based on the period of time the options are expected to be outstanding using historical data to estimate option exercise and employee termination; and dividend yield based on the Company's history and expectation of dividend payments. Stock options generally vest ratably over a four-year period and are exercisable over a period of up to ten years. The fair value of time-based restricted share units ("RSUs") and Performance RSUs is estimated on the date of grant and is generally equal to the closing stock price on that date. RSUs vest ratably over a period of four years and are settled in one share of the Company's common stock on the vesting date. Performance RSUs vest over a three year period from the date of grant if certain performance goals are achieved. The performance targets are based on the Company's fiscal year operating earnings (adjusted for certain amounts) as a percentage of contract revenues and the Company's fiscal year operating cash flow level. For the fiscal 2013 performance period, the performance targets exclude amounts attributable to significant businesses acquired in fiscal 2013, including acquisition, financing, and other related costs of the businesses acquired. Additionally, the awards include three year performance goals having similar measures as the fiscal year targets which, if met, result in supplemental shares awarded. For Performance RSUs, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if management determines it is probable that the performance criteria for the awards will be met. The total amount of stock-based compensation expense ultimately recognized is based on the number of awards that actually vest and fluctuates as a result of performance criteria for performance-based awards, as well as the vesting period of all stock-based awards. Accordingly, the amount of compensation expense recognized during any fiscal year may not be representative of future stock-based compensation expense. In accordance with ASC Topic 718, Compensation – Stock Compensation, compensation costs for performance-based awards are recognized over the requisite service period if it is probable that the performance goal will be satisfied. The Company uses its best judgment to determine probability of achieving the performance goals at each reporting period and recognizes compensation costs based on the estimate of the shares that are expected to vest. Fair Value of Financial Instruments – ASC Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820") defines and establishes a measurement framework for fair value and expands disclosure requirements. ASC Topic 820 requires that assets and liabilities carried at fair value are classified and disclosed in one of the following three categories: (1) Level 1 – Quoted market prices in active markets for identical assets or liabilities; (2) Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data; and (3) Level 3 – Unobservable inputs not corroborated by market data which require the reporting entity's own assumptions. The Company's financial instruments consist primarily of cash and equivalents, restricted cash, accounts and other receivables, income taxes receivable and payable, accounts payable and certain accrued expenses, and long-term debt. The carrying amounts of these items approximate fair value due to their short maturity, except for the Company's outstanding 7.125% senior subordinated notes due 2021 (the "2021 Notes") which are categorized as Level 2 as of July 27, 2013 and July 28, 2012, based on observable market-based inputs. See Note 10, Debt, for further information regarding the fair value of the 2021 Notes. The Company's cash and equivalents are categorized as Level 1 as of July 27, 2013 and July 28, 2012, based on quoted market prices in active markets for identical assets. During fiscal 2013 and 2012, the Company had no non-recurring fair value measurements of assets or liabilities subsequent to their initial recognition. Taxes Collected from Customers – ASC Topic 605, Taxes Collected from Customers and Remitted to Governmental Authorities, addresses the income statement presentation of any tax collected from customers and remitted to a government authority and provides that the presentation of taxes on either a gross basis or a net basis in an accounting policy decision that should be disclosed. The Company's policy is to present contract revenues net of sales taxes. Segment Information – The Company operates in one reportable segment as a specialty contractor, providing engineering, construction, maintenance and installation services to telecommunications providers, underground facility locating services to various utilities including telecommunications providers, and other construction and maintenance services to electric and gas utilities and others. All of the Company's operating segments have been aggregated into one reporting segment due to their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods. The Company's services are provided by its various subsidiaries throughout the United States and in Canada. Revenues from services provided in Canada were approximately $13.0 million, $11.9 million, and $7.4 million during fiscal 2013, 2012, 2011, respectively. The Company had no material long-lived assets in the Canadian operations at July 27, 2013 or July 28, 2012. Recently Issued Accounting Pronouncements Adoption of New Accounting Pronouncements In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income ("ASU 2011-05"). ASU 2011-05 requires the total of comprehensive income, the components of net income, and the components of other comprehensive income to be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 also requires entities to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income. The Company adopted ASU 2011-05 in fiscal 2013. In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220) ("ASU 2013-02"), which does not change the requirements for reporting net income or other comprehensive income in financial statements under ASU 2011-05; however, the amendments require entities to report either on the income statement or in a footnote to the financial statements, the effects on earnings from items that are classified out of accumulated other comprehensive income. The Company adopted ASU 2013-02 in fiscal 2013. The adoption of this guidance did not have a material effect on the Company's consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment ("ASU 2011-08"). ASU 2011-08 permits entities testing for goodwill impairment to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. ASU 2011-08 does not change how goodwill is determined or assigned to reporting units, nor does it revise the requirement to assess goodwill at least annually for impairment. ASU 2011-08 is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011. The Company adopted ASU 2011-08 in fiscal 2013. The adoption of this guidance did not have a material effect on the Company's consolidated financial statements. Accounting Standards Not Yet Adopted In July 2012, FASB issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment ("ASU 2012-02"). ASU 2012-02 amends Topic 350 by establishing an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. This update allows an entity the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. Under that option, an entity no longer would be required to calculate the fair value of the intangible asset unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The adoption of this guidance is not expected to have a material effect on the Company's consolidated financial statements. In July 2013, the FASB issued Accounting Standards Update No. 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 ("ASU 2013-11"). ASU 2013-11 provides guidance on the financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position 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. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013. The Company is currently evaluating the potential impact of ASU 2013-11 on its consolidated financial statements.

Accounting Policies

Basis of Presentation – Dycom Industries, Inc. ("Dycom" or the "Company") is a leading provider of specialty contracting services throughout the United States and in Canada. These services include engineering, construction, maintenance and installation services to telecommunications providers, underground facility locating services to various utilities, including telecommunications providers, and other construction and maintenance services to electric and gas utilities and others.

The consolidated financial statements include the results of Dycom and its subsidiaries, all of which are wholly-owned. All intercompany accounts and transactions have been eliminated and the financial statements reflect all adjustments, consisting of only normal recurring accruals that are, in the opinion of management, necessary for a fair presentation of such statements. These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC").

On December 3, 2012, the Company acquired substantially all of the telecommunications infrastructure service subsidiaries (the "Acquired Subsidiaries") of Quanta Services, Inc. Additionally, during the fourth quarter of fiscal 2013, the Company acquired Sage Telecommunications Corp of Colorado, LLC ("Sage") and certain assets of a tower construction and maintenance company. The results of operations of the businesses acquired are included in the accompanying consolidated financial statements from their respective dates of acquisition.

Accounting Period – The Company uses a fiscal year ending on the last Saturday in July.

Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported therein and accompanying notes. For the Company, key estimates include: recognition of revenue for costs and estimated earnings under the percentage of completion method of accounting, allowance for doubtful accounts, the fair value of reporting units for goodwill impairment analysis, the assessment of impairment of intangibles and other long-lived assets, the purchase price allocations of businesses acquired, accrued insurance claims, income taxes, asset lives used in computing depreciation and amortization, stock-based compensation expense for performance-based stock awards, and accruals for contingencies, including legal matters. At the time they are made, the Company believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole. However, actual results could differ from those estimates and such differences may be material to the financial statements.

Revenue Recognition – The Company recognizes revenues under the percentage of completion method of accounting using the units-of-delivery or cost-to-cost measures. A majority of the Company’s contracts are based on units-of-delivery and revenue is recognized as each unit is completed. Revenues from contracts using the cost-to-cost measures of completion are recognized based on the ratio of contract costs incurred to date to total estimated contract costs. Revenues from services provided under time and materials based contracts are recognized when the services are performed. The current asset "Costs and estimated earnings in excess of billings" represents revenues recognized in excess of amounts billed. The current liability "Billings in excess of costs and estimated earnings" represents billings in excess of revenues recognized.

Application of the percentage of completion method of accounting requires the use of estimates of costs to be incurred for the performance of the contract. The cost estimation process is based on the knowledge and experience of the Company’s project managers and financial professionals. Factors that the Company considers in estimating the work to be completed and ultimate contract recovery include the availability and productivity of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays in performance and the recoverability of any claims. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in changes to costs and income and their effects are recognized in the period in which the revisions are determined. At the time a loss on a contract becomes known, the entire amount of the estimated ultimate loss is accrued.

Cash and Equivalents – Cash and equivalents primarily include balances on deposit in banks. The Company maintains substantially all of its cash and equivalents at financial institutions it believes to be of high credit quality. To date, the Company has not experienced any loss or lack of access to cash in its operating accounts.

Restricted Cash – As of July 27, 2013 and July 28, 2012, the Company had approximately $3.7 million in restricted cash which is held as collateral in support of the Company's insurance obligations. Restricted cash is included in other current assets and other assets in the consolidated balance sheets and changes in restricted cash are reported in cash flows used in investing activities in the consolidated statements of cash flows.

Allowance for Doubtful Accounts – The Company maintains an allowance for doubtful accounts for estimated losses resulting from the failure of its customers to make required payments. Management analyzes the collectability of accounts receivable balances each period. This analysis considers the aging of account balances, historical bad debt experience, changes in customer creditworthiness, current economic trends, customer payment activity and other relevant factors. Should any of these factors change, the estimates made by management may also change, which could affect the level of the Company’s future provision for doubtful accounts.

Inventories – Inventories consist of materials and supplies used in the ordinary course of business and are carried at the lower of cost (using the first-in, first-out method) or market. Inventories also include certain job specific materials which are valued using the specific identification method. For contracts where the Company is required to supply part or all of the materials on behalf of the customer, the loss of the customer or declines in contract volumes could result in an impairment of the value of materials purchased.

Property and Equipment – Property and equipment are stated at cost and depreciated on a straight-line basis over their estimated useful lives (see Note 6, Property and Equipment, for the range of useful lives). Amortization of capital lease assets is included in depreciation expense. Maintenance and repairs are expensed as incurred and major improvements are capitalized. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in other income. Capitalized software is accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standard Codification ("ASC") Topic 350-40, Internal Use Software. Capitalized software consists primarily of costs to purchase and develop internal-use software and is amortized over its useful life as a component of depreciation expense. Property and equipment includes internally developed capitalized computer software gross cost and net book value of $18.3 million and $11.6 million, respectively, as of July 27, 2013, and gross cost and net book value of $11.6 million and $7.4 million, respectively, as of July 28, 2012.

Goodwill and Intangible Assets – The Company accounts for goodwill in accordance with ASC Topic 350, Intangibles-Goodwill and Other ("ASC Topic 350"). The Company's reporting units goodwill and other related indefinite-lived intangible assets are assessed annually as of the first day of the fourth fiscal quarter of each year in accordance with ASC Topic 350 in order to determine whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If the Company determines the fair value of goodwill or other indefinite-lived intangible assets is less than their carrying value as a result of the tests, an impairment loss is recognized. Impairment losses, if any, are reflected in operating income or loss in the consolidated statements of operations during the period incurred.

In accordance with ASC Topic 360, Impairment or Disposal of Long-Lived Assets, the Company reviews finite-lived intangible assets for impairment whenever an event occurs or circumstances change which indicates that the carrying amount of such assets may not be fully recoverable. Recoverability is determined based on an estimate of undiscounted future cash flows resulting from the use of an asset and its eventual disposition. An impairment loss is measured by comparing the fair value of the asset to its carrying value. If the Company determines the fair value of an asset is less than the carrying value, an impairment loss is incurred. Impairment losses, if any, are reflected in operating income or loss in the consolidated statements of operations during the period incurred.

The Company uses judgment in assessing if goodwill and intangible assets are impaired. Estimates of fair value are based on the Company's projection of revenues, operating costs, and cash flows taking into consideration historical and anticipated future results, general economic and market conditions, as well as the impact of planned business or operational strategies. To measure fair value, the Company employs a combination of present value techniques which reflect market factors. Changes in the Company's judgments and projections could result in significantly different estimates of fair value potentially resulting in additional impairments of goodwill and other intangible assets.

Business Combinations – The Company accounts for business combinations under the acquisition method of accounting. The purchase price of each acquired business is allocated to the tangible and intangible assets acquired and the liabilities assumed on the basis of their respective fair values on the date of acquisition. Any excess of the purchase price over the fair value of the separately identifiable assets acquired and the liabilities assumed is allocated to goodwill. The valuation of assets acquired and liabilities assumed requires a number of judgments and is subject to revision as additional information about the fair value of assets and liabilities becomes available. Additional information, which existed as of the acquisition date but at that time was unknown to the Company, may become known during the remainder of the measurement period, a period not to exceed twelve months from the acquisition date. Adjustments in the purchase price allocation may require a recasting of the amounts allocated to goodwill and intangible assets. In accordance with the acquisition method of accounting, acquisition costs are expensed as incurred.

Long-Lived Tangible Assets – The Company reviews long-lived tangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of an asset group and its eventual disposition. Measurement of an impairment loss is based on the fair value of the asset compared to its carrying value. Long-lived tangible assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

Accrued Insurance Claims – The Company retains the risk of loss, up to certain limits, for claims related to automobile liability, general liability, workers' compensation, employee group health, and locate damages. Locate damage claims result from property and other damages arising in connection with the Company's underground facility locating services. A liability for unpaid claims and the associated claim expenses, including incurred but not reported losses, is determined with the assistance of an actuary and reflected in the consolidated financial statements as accrued insurance claims. The liability for accrued claims and related accrued processing costs was $56.3 million and $48.8 million at July 27, 2013 and July 28, 2012, respectively, and included incurred but not reported losses of approximately $26.0 million and $22.3 million, respectively. Based on prior payment patterns for similar claims, the Company expects $29.1 million of the amount accrued at July 27, 2013 to be paid within the next twelve months.

The Company estimates the liability for claims based on facts, circumstances and historical evidence. When loss reserves are recorded they are not discounted, even though they will not be paid until sometime in the future. Factors affecting the determination of the expected cost for existing and incurred but not reported claims include, but are not limited to, the estimated number of future claims, the payment pattern of claims which have been incurred, changes in the medical condition of claimants, and other factors such as inflation, tort reform or other legislative changes, unfavorable jury decisions and court interpretations.

Income Taxes – The Company accounts for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event the Company determines that it would be able to realize its deferred income tax assets in the future in excess of their net recorded amount, it would make an adjustment to the valuation allowance, which would reduce the provision for income taxes.

ASC Topic 740, Income Taxes ("ASC Topic 740") prescribes a two-step process for the financial statement recognition and measurement of income tax positions taken or expected to be taken in an income tax return. The first step evaluates an income tax position in order to determine whether it is more likely than not that the position will be sustained upon examination, based on the technical merits of the position. The second step measures the benefit to be recognized in the financial statements for those income tax positions that meet the more likely than not recognition threshold. ASC Topic 740 also provides guidance on derecognition, classification, recognition and classification of interest and penalties, accounting in interim periods, disclosure and transition. Under ASC Topic 740, companies may recognize a previously unrecognized tax benefit if the tax position is effectively (as opposed to "ultimately") settled through examination, negotiation or litigation.

Per Share Data – Basic earnings per common share is computed based on the weighted average number of shares outstanding during the period, excluding unvested restricted share units. Diluted earnings per common share includes the weighted average common shares outstanding for the period and dilutive potential common shares, including unvested restricted share units. Performance vesting restricted share units are only included in diluted earnings per common share calculations for the period if all the necessary performance conditions are satisfied and their impact is dilutive. Common stock equivalents related to stock options are excluded from diluted earnings per common share calculations if their effect would be anti-dilutive.

Stock-Based Compensation – The Company's stock-based award programs are intended to attract, retain and reward talented employees, officers and directors, and to align stockholder and employee interests. Stock-based awards are granted by the Company under its 2012 Long-Term Incentive Plan ("2012 Plan"), 2003 Long-Term Incentive Plan ("2003 Plan"), and the 2007 Non-Employee Directors Equity Plan ("2007 Directors Plan" and, together with the 2012 Plan and 2003 Plan, the "Plans"). The Company also has several other plans, both expired and current, under which awards are outstanding but under which no further awards will be granted. The Company's policy is to issue new shares to satisfy equity awards under the Plans. The Plans provide for the grants of a number of types of stock-based awards, including stock options, restricted shares, performance shares, restricted share units, performance share units ("Performance RSUs"), and stock appreciation rights. The total number of shares available for grant under the Plans as of July 27, 2013 was 2,033,272.

Compensation expense for stock-based awards is based on the fair value at the measurement date and is included in general and administrative expenses in the consolidated statements of operations. The fair value of stock option grants is estimated on the date of grant using the Black-Scholes option pricing model based on certain assumptions including: expected volatility based on the historical price of the Company's stock over the expected life of the option; the risk free rate of return based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option; the expected life based on the period of time the options are expected to be outstanding using historical data to estimate option exercise and employee termination; and dividend yield based on the Company's history and expectation of dividend payments. Stock options generally vest ratably over a four-year period and are exercisable over a period of up to ten years.

The fair value of time-based restricted share units ("RSUs") and Performance RSUs is estimated on the date of grant and is generally equal to the closing stock price on that date. RSUs vest ratably over a period of four years and are settled in one share of the Company's common stock on the vesting date. Performance RSUs vest over a three year period from the date of grant if certain performance goals are achieved. The performance targets are based on the Company's fiscal year operating earnings (adjusted for certain amounts) as a percentage of contract revenues and the Company's fiscal year operating cash flow level. For the fiscal 2013 performance period, the performance targets exclude amounts attributable to significant businesses acquired in fiscal 2013, including acquisition, financing, and other related costs of the businesses acquired. Additionally, the awards include three year performance goals having similar measures as the fiscal year targets which, if met, result in supplemental shares awarded. For Performance RSUs, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if management determines it is probable that the performance criteria for the awards will be met.

The total amount of stock-based compensation expense ultimately recognized is based on the number of awards that actually vest and fluctuates as a result of performance criteria for performance-based awards, as well as the vesting period of all stock-based awards. Accordingly, the amount of compensation expense recognized during any fiscal year may not be representative of future stock-based compensation expense. In accordance with ASC Topic 718, Compensation – Stock Compensation, compensation costs for performance-based awards are recognized over the requisite service period if it is probable that the performance goal will be satisfied. The Company uses its best judgment to determine probability of achieving the performance goals at each reporting period and recognizes compensation costs based on the estimate of the shares that are expected to vest.

Fair Value of Financial Instruments – ASC Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820") defines and establishes a measurement framework for fair value and expands disclosure requirements. ASC Topic 820 requires that assets and liabilities carried at fair value are classified and disclosed in one of the following three categories: (1) Level 1 – Quoted market prices in active markets for identical assets or liabilities; (2) Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data; and (3) Level 3 – Unobservable inputs not corroborated by market data which require the reporting entity's own assumptions. The Company's financial instruments consist primarily of cash and equivalents, restricted cash, accounts and other receivables, income taxes receivable and payable, accounts payable and certain accrued expenses, and long-term debt. The carrying amounts of these items approximate fair value due to their short maturity, except for the Company's outstanding 7.125% senior subordinated notes due 2021 (the "2021 Notes") which are categorized as Level 2 as of July 27, 2013 and July 28, 2012, based on observable market-based inputs. See Note 10, Debt, for further information regarding the fair value of the 2021 Notes. The Company's cash and equivalents are categorized as Level 1 as of July 27, 2013 and July 28, 2012, based on quoted market prices in active markets for identical assets. During fiscal 2013 and 2012, the Company had no non-recurring fair value measurements of assets or liabilities subsequent to their initial recognition.

Taxes Collected from Customers – ASC Topic 605, Taxes Collected from Customers and Remitted to Governmental Authorities, addresses the income statement presentation of any tax collected from customers and remitted to a government authority and provides that the presentation of taxes on either a gross basis or a net basis in an accounting policy decision that should be disclosed. The Company's policy is to present contract revenues net of sales taxes.

Segment Information – The Company operates in one reportable segment as a specialty contractor, providing engineering, construction, maintenance and installation services to telecommunications providers, underground facility locating services to various utilities including telecommunications providers, and other construction and maintenance services to electric and gas utilities and others. All of the Company's operating segments have been aggregated into one reporting segment due to their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods. The Company's services are provided by its various subsidiaries throughout the United States and in Canada. Revenues from services provided in Canada were approximately $13.0 million, $11.9 million, and $7.4 million during fiscal 2013, 2012, 2011, respectively. The Company had no material long-lived assets in the Canadian operations at July 27, 2013 or July 28, 2012.

Recently Issued Accounting Pronouncements

Adoption of New Accounting Pronouncements

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income ("ASU 2011-05"). ASU 2011-05 requires the total of comprehensive income, the components of net income, and the components of other comprehensive income to be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 also requires entities to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income. The Company adopted ASU 2011-05 in fiscal 2013.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220) ("ASU 2013-02"), which does not change the requirements for reporting net income or other comprehensive income in financial statements under ASU 2011-05; however, the amendments require entities to report either on the income statement or in a footnote to the financial statements, the effects on earnings from items that are classified out of accumulated other comprehensive income. The Company adopted ASU 2013-02 in fiscal 2013. The adoption of this guidance did not have a material effect on the Company's consolidated financial statements.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment ("ASU 2011-08"). ASU 2011-08 permits entities testing for goodwill impairment to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. ASU 2011-08 does not change how goodwill is determined or assigned to reporting units, nor does it revise the requirement to assess goodwill at least annually for impairment. ASU 2011-08 is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011. The Company adopted ASU 2011-08 in fiscal 2013. The adoption of this guidance did not have a material effect on the Company's consolidated financial statements.

Accounting Standards Not Yet Adopted

In July 2012, FASB issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment ("ASU 2012-02"). ASU 2012-02 amends Topic 350 by establishing an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. This update allows an entity the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. Under that option, an entity no longer would be required to calculate the fair value of the intangible asset unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The adoption of this guidance is not expected to have a material effect on the Company's consolidated financial statements.

In July 2013, the FASB issued Accounting Standards Update No. 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 ("ASU 2013-11"). ASU 2013-11 provides guidance on the financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position 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. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013. The Company is currently evaluating the potential impact of ASU 2013-11 on its consolidated financial statements.
