Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and 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. The Company provides program management, engineering, construction, maintenance and installation services for telecommunications providers, underground facility locating services for various utilities, including telecommunications providers, and other construction and maintenance services for electric and gas utilities. The accompanying unaudited condensed 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. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Operating results for the interim period are not necessarily indicative of the results expected for any other interim period or for the full fiscal year. These condensed consolidated financial statements and accompanying notes should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in this report and the Company’s audited financial statements for the year ended July 30, 2016 included in the Company’s Annual Report on Form 10-K for the year ended July 30, 2016, filed with the SEC on August 31, 2016. Segment Information – The Company operates in one reportable segment. Its services are provided by its operating segments on a decentralized basis. Each operating segment consists of a subsidiary (or in certain instances, the combination of two or more subsidiaries). Management of the operating segments report to the Company’s Chief Operating Officer who reports to the Chief Executive Officer, the chief operating decision maker. All of the Company’s operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods. The Company’s operating segments provide services throughout the United States and in Canada. Revenues from services provided in Canada were not material during the three months ended October 29, 2016 and October 24, 2015. Additionally, the Company had no material long-lived assets in Canada as of October 29, 2016 or July 30, 2016. Accounting Period – The Company’s fiscal year ends on the last Saturday in July. As a result, each fiscal year consists of either 52 weeks or 53 weeks of operations (with the additional week of operations occurring in the fourth quarter). Fiscal 2016 consisted of 53 weeks of operations and fiscal 2017 will consist of 52 weeks of operations. Significant Accounting Policies & Estimates 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 in these condensed consolidated financial statements and accompanying notes. These estimates are based on the Company’s historical experience and management’s understanding of current facts and circumstances. 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 materially from those estimates. There have been no material changes to the Company’s significant accounting policies and critical accounting estimates described in the Company’s Annual Report on Form 10-K for the year ended July 30, 2016. Revenue Recognition. The Company performs a majority of its services under master service agreements and other agreements that contain customer-specified service requirements, such as discrete pricing for individual tasks. Revenue is recognized under these arrangements based on units-of-delivery as each unit is completed. The remainder of the Company’s services, representing less than 5% of its contract revenues during the three months ended October 29, 2016 and less than 10% of its contract revenues during the three months ended October 24, 2015, are performed under contracts using the cost-to-cost measure of the percentage of completion method of accounting. Revenue is recognized under these arrangements based on the ratio of contract costs incurred to date to total estimated contract costs. For contracts using the cost-to-cost measure of the percentage of completion method of accounting, the Company accrues the entire amount of a contract loss at the time the loss is determined to be probable and can be reasonably estimated. During the three months ended October 29, 2016 and October 24, 2015, there was no material impact to the Company’s results of operations due to changes in contract estimates. There were no material amounts of unapproved change orders or claims recognized during the three months ended October 29, 2016 or October 24, 2015. 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. Restricted Cash – As of October 29, 2016 and July 30, 2016, the Company had approximately $5.5 million and $5.0 million, respectively, in restricted cash, which is held as collateral in support of the Company’s insurance obligations. Restricted cash is included in other assets in the condensed consolidated balance sheets and changes in restricted cash are reported in cash flows used in investing activities in the condensed consolidated statements of cash flows. Other Assets – As of October 29, 2016 and July 30, 2016, other non-current assets consist of deferred financing costs related to the Company’s revolving credit facility of $5.9 million and $6.4 million, respectively, insurance recoveries/receivables related to accrued claims of $5.6 million and $5.7 million, respectively, as well as long-term deposits, prepaid discounts, and other non-current assets totaling $18.0 million and $17.7 million, respectively. As of October 29, 2016 and July 30, 2016, other non-current assets also included $4.0 million for an investment in nonvoting senior units of a former customer, which is accounted for using the cost method. Fair Value of Financial Instruments – The Company’s financial instruments primarily consist of cash and equivalents, restricted cash, accounts receivable, income taxes receivable and payable, accounts payable, certain accrued expenses, and long-term debt. The carrying amounts of these items approximate fair value due to their short maturity, except for certain of the Company’s outstanding long-term debt which is based on observable market-based inputs (Level 2). See Note 10, Debt, for further information regarding the fair value of such financial instruments. The Company’s cash and equivalents are based on quoted market prices in active markets for identical assets (Level 1) as of October 29, 2016 and July 30, 2016. During the three months ended October 29, 2016 and October 24, 2015, the Company had no material nonrecurring fair value measurements of assets or liabilities subsequent to their initial recognition. Recently Issued Accounting Pronouncements There have been no changes in the expected dates of adoption or estimated effects on the Company’s consolidated financial statements of recently issued accounting pronouncements from those disclosed in the Company’s Annual Report on Form 10-K for the year ended July 30, 2016 filed with the SEC on August 31, 2016. Accounting standards adopted during the period covered in this Quarterly Report on Form 10-Q and recently issued accounting pronouncements are discussed below. Recently Adopted Accounting Standards Business Combinations - In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 replaces the requirement for an acquirer in a business combination to retrospectively adjust provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill when measurement period adjustments are identified. The new guidance requires an acquirer to recognize adjustments in the reporting period in which the adjustment amounts are determined. The acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. Additionally, the acquirer must present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date. The Company adopted ASU 2015-16 during the first quarter of fiscal 2017 and it did not have a material effect on the Company’s consolidated financial statements. Accounting Standards Not Yet Adopted Income Taxes - In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”). ASU 2016-16 amends the current GAAP prohibition of recognizing current and deferred income taxes for intra-entity asset transfers until the asset has been sold to an outside party. The update requires an entity to recognize the income tax consequences of an intra-entity transfer for assets other than inventory when the transfer occurs. ASU 2016-16 will be effective for the Company in fiscal 2019 and interim reporting periods within that year. Early adoption is permitted as of the beginning of an interim or annual reporting period. The Company expects the adoption of this guidance will not have a material effect on the Company’s consolidated financial statements. Statement of Cash Flows - In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 is intended to reduce the diversity in practice regarding the classification of certain transactions within the statement of cash flows. ASU 2016-15 will be effective for the Company in fiscal 2019 and interim reporting periods within that year. Early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the effect of the adoption of this guidance on the Company’s consolidated financial statements.
