Overview and Basis of Presentation [Abstract]

Note 1. Overview and Basis of Presentation

Company and Background

Workday provides enterprise cloud-based applications for human capital management (HCM), payroll, financial management, time tracking, procurement and employee expense management. We offer innovative and adaptable technology focused on the consumer Internet experience and cloud delivery model. Our applications are designed for global enterprises to manage complex and dynamic operating environments. We provide our customers highly adaptable, accessible and reliable applications to manage critical business functions that enable them to optimize their financial and human capital resources. We were incorporated in March 2005 in Nevada. In June 2012, we reincorporated in Delaware.

Basis of Presentation

These unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 with the SEC on October 15, 2012. There have been no changes to our significant accounting policies described in the prospectus that have had a material impact on our consolidated financial statements and related notes.

The consolidated balance sheet as of January 31, 2012, included herein was derived from the audited financial statements as of that date. These unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, our comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending January 31, 2013.

We changed our fiscal year end from December 31 to January 31, commencing with our fiscal year ended January 31, 2012.

Initial Public Offering

In October 2012, we completed our initial public offering (“IPO”) in which we issued and sold 26.2 million shares of Class A common stock at a public offering price of $28.00 per share. We received net proceeds of $684.6 million after deducting underwriting discounts and commissions of $44.0 million and other offering expenses of $4.0 million. Upon the closing of the IPO, all shares of our then-outstanding redeemable convertible preferred stock and convertible preferred stock automatically converted into an aggregate of 98.0 million shares of Class B common stock and an aggregate of 42.1 million shares of our then outstanding common stock converted into an equal number of Class B common stock.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. These estimates include, but are not limited to, the determination of the relative selling prices for our services, the recoverability of deferred costs and certain assumptions used in the valuation of equity awards. Actual results could differ from those estimates and such differences could be material to our consolidated financial position and results of operations.
