Accounting Policies [Abstract]
The Company and Summary of Significant Accounting Policies	The Company and Summary of Significant Accounting Policies Vocera Communications, Inc. (“Vocera” or the “Company”) is a provider of mobile communication solutions focused on addressing critical communication challenges facing hospitals today. Vocera helps its customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through its Voice Communication, Secure Messaging, and Care Transition solutions. The Voice Communication solution, which includes a lightweight, wearable, voice-controlled communication badge and a software platform, enables users to connect instantly with other hospital staff simply by saying the name, function or group name of the desired recipient. The Secure Messaging solution securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers. The Care Transition solution is a hosted voice and text based software application that captures, manages and monitors patient information when responsibility for the patient is transferred or “handed-off” from one caregiver to another, or when the patient is discharged from the hospital. These three solutions are complemented by our ExperiaHealth business, which is focused on improving patient experience. Vocera was incorporated in Delaware on February 16, 2000. Vocera formed wholly owned subsidiaries Vocera Communications UK Limited and Vocera Communications Australia Pty Limited. in 2005, and Vocera Hand-Off, Inc., Vocera Canada, Limited. and ExperiaHealth, Inc. in 2010. The Company completed its initial public offering of common stock on April 2, 2012 in accordance with the Securities Act of 1933, as amended. The Company sold 5,000,000 shares and certain of its stockholders sold 1,727,000 shares, including 877,500 shares for the underwriters' over-allotment option, through a firm commitment underwritten, public offering. The shares were sold at the initial public offering price of $16.00 per share for aggregate gross offering proceeds of $80.0 million to the Company and $27.6 million to the selling stockholders. See Note 12, Subsequent Events for additional information. Basis of presentation The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission, and include the accounts of Vocera and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto contained in the Company's prospectus for its initial public offering filed with the Securities and Exchange Commission on March 28, 2012. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim consolidated financial information. The results for the quarter presented are not necessarily indicative of the results to be expected for the year ending December 31, 2012 or for any other interim period or any other future year. Use of Estimates The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting periods. The estimates include, but are not limited to, revenue recognition, useful lives assigned to long-lived assets, the valuation of common and preferred stock and related warrants and options, stock-based compensation expense, provisions for income taxes and contingencies. Actual results could differ from these estimates, and such differences could be material to the Company’s financial position and results of operations. Fair Value of Financial Instruments The carrying value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, deposits, accounts payable, accrued liabilities and accrued compensation approximates fair value due to their short maturities. Cash and cash equivalents are carried at fair value. The carrying value of the Company’s line of credit and bank loans approximate fair value based on current rates offered to the Company for similar debt instruments. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued new disclosure guidance related to the presentation of the statement of comprehensive income. This guidance eliminates the current option to report other comprehensive income and its components in the consolidated statement of stockholders’ equity. The requirement to present reclassification adjustments out of accumulated other comprehensive income on the face of the consolidated statement of income has been deferred. The Company adopted this accounting standard effective January 1, 2012. The Company does not have any comprehensive income so the adoption of this standard did not have any impact on the financial presentation of the Company. In September 2011, the FASB issued new accounting guidance that simplifies goodwill impairment tests. The new guidance states that a “qualitative” assessment may be performed to determine whether further impairment testing is necessary. An entity will no longer be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Prior to the amendment, entities were required to test goodwill for impairment, on at least an annual basis, by first comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit is calculated as being less than its carrying amount, then the second step of the quantitative test is to be performed to measure the amount of impairment loss, if any. The Company adopted this accounting standard effective January 1, 2012, and does not expect that this standard will have a material impact on the financial position or results of operations of the Company. The Company qualifies as an "emerging growth company" pursuant to the provisions of the JOBS Act, enacted on April 5, 2012. Section 102 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. However, the Company is choosing to "opt out" of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. The decision to opt out of the extended transition period is irrevocable.
