Basis of Presentation and Summary of Critical Accounting Policies	Basis of Presentation and Summary of Critical Accounting Policies In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions affecting the reported amounts therein. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. The balance sheet at April 26, 2014 has been derived from the audited financial statements at that date, but it does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. These financial statements should be read in conjunction with our financial statements and notes thereto for the year ended April 26, 2014, which are contained in our Annual Report on Form 10-K previously filed with the Securities and Exchange Commission. The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year. Daktronics, Inc. operates on a 52 to 53 week fiscal year, with our fiscal year ending on the Saturday closest to April 30 of each year. When April 30 falls on a Wednesday, the fiscal year ends on the preceding Saturday. Within each fiscal year, each quarter is comprised of 13 week periods following the beginning of each fiscal year. In each 53 week year, each of the last three quarters is comprised of a 13 week period, and an additional week is added to the first quarter of that fiscal year. The fiscal year ended April 26, 2014 consisted of 52 weeks. Fiscal 2015 will be a 53-week year; therefore, the quarter ended August 2, 2014 contains operating results for 14 weeks while the quarter ended July 27, 2013 contains operating results for 13 weeks. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 changes the criteria for determining which disposals should be presented as discontinued operations and modifies the related disclosure requirements. Additionally, the new guidance requires that a business that qualifies as held for sale upon acquisition should be reported as discontinued operations. The new guidance is effective for us beginning in fiscal 2016 and applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, as a new topic, Accounting Standards Codification ("ASC") 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. ASU 2014-09 is effective for us beginning in fiscal 2018 and can be adopted either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We are currently evaluating the effect that adopting this new accounting guidance will have on our consolidated results of operations, cash flows, and financial position.
