Amendment Description	The Registrant is filing this Amendment No. 1 on Form 10-K/A (this "Amended Filing") to its Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (the "Original Filing") to: (i) reissue the Report of Independent Registered Public Accounting Firm to change the firm's opinion regarding the effectiveness of the Registrant's internal control over financial reporting as of December 31, 2013; (ii) restate management's conclusions regarding internal control over financial reporting and disclosure controls and procedures as of December 31, 2013; (iii) add discussion of the risks associated with a material weakness in internal control over financial reporting as of December 31, 2013; and (iv) revise the financial statements to correct certain immaterial errors in the accounting for liabilities for charitable contributions and liabilities for certain purchase orders in fiscal years 2011, 2012 and 2013. Accordingly, the Registrant hereby amends and replaces in their entirety Items 1A, 6, 7, 8, 9A, and 15 in the Original Filing. Management has concluded that there are material weaknesses in internal controls over financial reporting, as management did not design and maintain effective monitoring controls related to the design and operating effectiveness of certain control activities, including certain controls involving an inherent level of complexity, subjectivity, and judgment related to the following business processes: revenue and accounts receivable, period-end financial reporting, goodwill and intangible assets, hedging, income taxes, business combinations, and stock-based compensation. Specifically, management did not maintain sufficient documentation or perform a sufficient review of certain control activities due to an insufficient complement of personnel with an appropriate level of experience, training and lines of reporting necessary to monitor control activities to allow for an effective internal control over financial reporting compliance group. While these material weaknesses did not result in any material misstatement of the Company?s historical financial statements, they did result in adjustments to accrued liabilities, cost of revenues, and operating expenses and revisions to its consolidated financial statements for fiscal years 2013, 2012 and 2011, and interim periods in 2014 and 2013. Additionally, these material weaknesses could result in a misstatement of the account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. As required by Rule 12b-15, the Registrant's principal executive officer and principal financial officer are providing new currently dated certifications. In addition, the Registrant is filing a new consent of PricewaterhouseCoopers LLP. Accordingly, the Registrant hereby amends Item 15 in the Original Filing to reflect the filing of the new certifications and consent. Except as described above, this Amended Filing does not amend, update or change any other items or disclosures in the Original Filing and does not purport to reflect any information or events subsequent to the filing date of the Original Filing. As such, this Amended Filing speaks only as of the date the Original Filing was filed, and the Registrant has not undertaken herein to amend, supplement or update any information contained in the Original Filing to give effect to any subsequent events. Accordingly, this Amended Filing should be read in conjunction with the Registrant's filings made with the Securities and Exchange Commission subsequent to the filing of the Original Filing, including any amendment to those filings.
