	The Company and Summary of Significant Accounting Policies
	Organization and Business
	Vocera Communications, Inc. (the “Company”) is a provider of secure, integrated, intelligent communication solutions, focused on empowering mobile workers in healthcare, hospitality, energy, and other mission-critical mobile work environments, in the United States and internationally. The majority of the Company's business is currently generated from sales of its solutions in the healthcare market, but the Company is actively engaged in other markets. Vocera helps its healthcare customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through its Communication and Care Experience solutions. These have been installed in more than 1,200 healthcare and non-healthcare organizations worldwide.
	The Vocera Communication System, which includes an intelligent enterprise software platform, a lightweight, wearable, voice-controlled communication badge, and smartphone applications, enables users to connect instantly with other staff simply by saying the name, function or group name of the desired recipient. It also securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers. The Vocera Care Experience is a hosted software solution suite that coordinates and streamlines patient-to-provider and provider-to-provider communication across the continuum of care. Vocera Care Experience is complemented by the Company’s Experience Innovation Network, a membership-based program to spread the adoption of leading strategies to improve patient and staff experience.
	The Company was incorporated in Delaware on February 16, 2000. The Company formed wholly-owned subsidiaries Vocera Communications UK Ltd and Vocera Communications Australia Pty Ltd. in 2005, Vocera Canada, Ltd. in 2010, Vocera Communications India Private Ltd. in 2013 and Vocera Communications Middle East FZ-LLC in 2014.
	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 intercompany balances and transactions have been eliminated. Certain information and disclosures normally included in 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 Annual Report on Form 10-K for the year ended December 31, 2013. The year-end condensed balance sheet data was derived from the Company's 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, 2014 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, excess and obsolete inventory charges, warranty reserves, 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.
	Revenue Recognition
	The Company derives revenue from the sales of communication badges, smartphone application software, perpetual software licenses for enterprise software that is essential to the functionality of the communication badges, software maintenance, extended warranty and professional services. The Company also derives revenue from the sale of perpetual and subscription licenses for software that is not essential to the functionality of the communication badges. The Company's revenue recognition policy has not changed from that described in its Annual Report on Form 10-K for the year ended December 31, 2013.
	A portion of the Company's sales are made through multi-year lease agreements with customers. When these arrangements are considered sales-type leases, upon delivery of leased products to customers, the Company recognizes revenue for such products in an amount equal to the net present value of the minimum lease payments. Unearned income is recognized as part of product revenue under the effective interest method. The Company recognizes revenue related to executory costs when such executory costs are incurred.
	Proceeds from transfers of sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as financing liabilities.
	For the six months ended June 30, 2014 and 2013, the Company transferred $0.5 million and $0.8 million, respectively of lease receivables in non-recourse sales to third-party financial companies, with immaterial net gains. For the six months ended June 30, 2014 and 2013, the Company recorded $0.3 million and $0.6 million, respectively, of financing liabilities for future performance of executory service obligations. For lease receivables retained as of June 30, 2014 and December 31, 2013, the Company recorded $1.2 million and $1.4 million of net investment in sales-type leases, respectively, equivalent to the minimum lease payments less the unearned interest portion.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued new guidance for the gross versus net presentation of unrecognized tax benefits. The FASB concluded that an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss (“NOL”) or other tax credit carryforward when settlement in this manner is available under the tax law. The new guidance was effective for the Company's first quarter of 2014, applied prospectively. Adoption of this standard was not significant to the Company's financial position or results of operations.
	In April 2014, the FASB issued revised guidance for reporting discontinued operations and disclosures of disposals of components of an entity. Under the new guidance, only disposals representing a strategic shift in the entity’s operations and financial results will be presented as discontinued operations. In addition, the new guidance requires certain expanded disclosures about discontinued operations and limited disclosures for a disposal not qualifying for such reporting. The Company’s effective date for these amendments will be the first quarter of 2015, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s financial position or results of operations.
	In May 2014, the FASB together with the International Accounting Standards Board issued converged guidance for revenue recognition that will replace most existing guidance, eliminate industry-specific guidance and provide a unified model for determining how and when revenue from contracts with customers should be recognized. Under the new guidance, an entity 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 standard will also introduce additional disclosures, changes in asset and liability accounting, and changes in gain/loss recognition for asset transfers unrelated to customer transactions.
	The Company’s effective date for this standard will be the first quarter of 2017; no early application is permitted. Two methods of transition are provided: a full retrospective approach, with certain practical expedients allowed, and a cumulative effect method, with balance sheet adjustment as of January 1, 2017. The Company is evaluating the effect the new standard will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the future effect of the standard on its financial position or results of operations.

	Fair Value of Financial Instruments
	The Company’s cash and cash equivalents and short-term investments are carried at their fair values with any differences from their amortized cost recorded in equity as unrealized gains (losses) on marketable securities. As a basis for determining the fair value of its assets and liabilities, the Company established a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. For the six months ended June 30, 2014, there have been no transfers between Level 1 and Level 2 fair value instruments and no transfers in or out of Level 3.
	The Company's money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The fair value of the Company's Level 2 fixed income securities are obtained from independent pricing services, which may use quoted market prices for identical or comparable instruments or model-driven valuations using observable market data or other inputs corroborated by observable market data. The Company does not have any financial instruments which are valued using Level 3 inputs.
	The Company’s assets that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of June 30, 2014 and December 31, 2013, are summarized as follows (in thousands):

	The Company has determined that the unrealized losses on its short-term investments as of June 30, 2014 and December 31, 2013 do not constitute an "other than temporary impairment." The unrealized losses for the short-term investments have all been in a continuous unrealized loss position for less than twelve months. The Company’s conclusion of no “other than temporary impairment” is based on the high credit quality of the securities, their short remaining maturity (less than five months, weighted average) and the Company’s intent and ability to hold such loss securities until maturity.

Income (loss) per share	'
	Net Loss Per Share
	For fiscal years preceding 2013, basic and diluted net (loss) income per common share were presented in conformity with the two-class method required for participating securities.
	For the three months and the six months ended June 30, 2014 and 2013, the two-class method is not applicable due to the net losses, which must be attributed entirely to the common shareholders. Additionally, as of June 30, 2014 and December 31, 2013, there were 8,094 and 26,463 shares of participating securities, respectively, consisting of repurchasable shares issued from early exercise of options and unvested restricted shares; thus the future effect of participating securities would generally be immaterial, even in years with net income.
	The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share amounts):

	Acquisition-related intangible assets are amortized either straight-line, or over the life of the assets on a basis that resembles the economic benefit of the assets. This yields amortization in the latter case that is higher in earlier periods of the useful life.
	The gross carrying amounts of intangible assets which have been fully amortized are removed annually in the subsequent first quarter balance sheet presentation. During the six months ended June 30, 2014, a fully amortized non-compete agreement intangible with $70,000 original cost (and accumulated amortization) was removed from the table of intangibles carrying cost, offset by increases in intangibles related to the mVisum acquisition, as described in Note 11.
	The estimated useful lives and carrying value of acquired intangible assets are as follows:
				June 30, 2014						December 31, 2013
	(in thousands)	Range of		Gross		Accumulated		Net		Gross		Accumulated		Net

	Intangible assets			$	5,600	$	3,136	$	2,464	$	4,370	$	2,826	$	1,544
	Amortization expense was $0.2 million and $0.2 million for the three months ended June 30, 2014 and 2013, respectively. Amortization expense was $0.4 million and $0.4 million for the six months ended June 30, 2014 and 2013, respectively.
	Amortization of acquired intangible assets is reflected in the cost of revenue or operating expenses, depending on the nature of the intangible. The estimated future amortization of existing acquired intangible assets as of June 30, 2014 was as follows:
	(in thousands)		Future amortization
	2014 (remaining six months)		$	405
	2015		626

	Commitments and Contingencies
	Non-cancelable Material Commitments
	The Company is required to purchase unused, non-cancelable, non-returnable raw material inventory that was purchased by its contract manufacturers based on committed finished goods orders from the Company, certain long lead-time raw materials based on the Company’s forecast and current work-in-progress materials. As of June 30, 2014 and December 31, 2013, approximately $3.2 million and $3.1 million, respectively, of such inventory was purchased and held by the third-party manufacturers which was subject to these purchase guarantees.
	Leases
	The Company leases office space for its headquarters and subsidiaries under non-cancelable operating leases, which will expire between December 2014 and April 2017. The San Jose, California headquarters lease expires on March 31, 2016, with a single three-year extension option at rates approximating the then-fair market value. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid. Facilities rent expense was $0.5 million and $0.5 million for the three months ended June 30, 2014 and June 30, 2013, respectively. Facilities rent expense was $1.0 million and $1.0 million for the six months ended June 30, 2014 and June 30, 2013, respectively.
	Future minimum lease payments at June 30, 2014 under non-cancelable operating leases are as follows:
	(in thousands)	Operating leases
	2014 (remaining six months)	$	865
	2015	1,693
	2016	539
	2017	33
	Total minimum lease payments	$	3,130
	Indemnifications
	The Company undertakes, in the ordinary course of business, to (i) defend customers and other parties from certain third-party claims associated with allegations of trade secret misappropriation, infringement of copyright, patent or other intellectual property right, or tortious damage to persons or property and (ii) indemnify and hold harmless such parties from certain resulting damages, costs and other liabilities. The term of these undertakings may be perpetual and the maximum potential liability of the Company under certain of these undertakings is not determinable. Based on its historical experience, the Company believes the liability associated with these undertakings is minimal.
	The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The Company currently has directors and officers insurance. As there has been no significant history of losses, no expense accrual has been made.
	Securities Litigation
	On August 1, 2013, a purported securities class action entitled Michael Brado v. Vocera Communications Inc., et al. was filed in the United States District Court for the Northern District of California, against the Company and certain of its officers, its board of directors, a former director and the underwriters for the Company's initial public offering. A second purported securities class action, entitled Duncan v. Vocera Communications Inc., et al., was filed on August 21, 2013, also in the Northern District of California, against the same parties. On September 27, 2013, the Court ordered the matters related. The suits purport to allege claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Section 10(b) and 20(a) of the Exchange Act of 1934 for allegedly misleading statements in the registration statement for the Company's initial public offering and in subsequent communications regarding its business and financial results. The suits are purportedly brought on behalf of purchasers of the Company's securities between March 28, 2012 and May 3, 2013, and seek compensatory damages, rescission, fees and costs, as well as equitable and injunctive or other relief. The plaintiffs’ motion for consolidation of the actions and for appointment of lead plaintiff has been granted, and the Company anticipates that the plaintiffs will file an amended consolidated complaint.  No responses to the current complaints are due at this time.
	Due to the inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of this matter. The Company is unable at this time to determine whether the outcome of the litigation would have a material impact on its results of operations, financial condition or cash flow. The Company has not established any reserve for any potential liability relating to this lawsuit, because this contingency is not considered probable and reasonably estimable.
	From time to time, the Company may be involved in other lawsuits, claims, investigations and proceedings, consisting of intellectual property, commercial, employment and other matters which arise in the ordinary course of business.

Segment Reporting [Abstract]	'
Segments	'
	Segments
	The Company has two operating segments which are both reportable business segments: (i) Product and (ii) Service, both of which are comprised of Vocera’s and its wholly-owned subsidiaries’ results of operations. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer.
	The CODM regularly receives information related to revenue, cost of revenue, and gross profit for each operating segment, and uses this information to assess performance and make resource allocation decisions. All other financial information, including operating expenses and assets, is prepared and reviewed by the CODM on a consolidated basis. Assets are not a measure used to assess the performance of the Company by the CODM; therefore, the Company does not report assets by segment internally or in its financial statements.
	The following table presents a summary of the operating segments:

	Income Taxes
	The provision for income taxes was $140,000 and $112,000 for the six months ended June 30, 2014 and 2013, respectively. The expense in both periods was primarily due to taxes on international operations and state income taxes.
	As of June 30, 2014, the Company has provided a valuation allowance against certain federal and state deferred tax assets.
	Management continues to evaluate the realizability of deferred tax assets and the related valuation allowance. If management's assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the
	related adjustment to income during the period in which management makes the determination.
	As of June 30, 2014, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2013.

	Business acquisition
	On January 13, 2014, the Company acquired certain assets and certain liabilities of mVisum, Inc. (“mVisum”), an innovative provider of alarm management technology solutions for health systems, for $3.5 million in cash. The acquisition enabled the Company to enhance its existing platform with complementary communications solutions for healthcare and other mission-critical environments.
	The following table presents the fair value of the identifiable assets acquired and liabilities assumed as of the acquisition date:
	(in thousands)	Fair value of net assets acquired
	Accounts receivable	$	187
	Intangibles
	Developed technology	830
	Non-compete agreement	260
	Customer relationships	170
	Trademarks and trade names	40
	Goodwill	2,103
	Total assets	3,590
	Deferred revenue	(90		)
	Net assets acquired	$	3,500
	The estimated fair values of identifiable intangible assets were primarily determined using discounted cash flow models. The acquired intangible assets are amortized over their estimated useful lives of 4.0 to 7.0 years with a weighted average amortization period of 5.7 years.
	The excess of the acquisition consideration over the fair values of the underlying net assets acquired was recorded as goodwill. Goodwill is largely attributable to the synergy of mVisum’s proprietary solutions with the Company’s existing customer base, dedicated sales force and cross selling opportunities with the Company’s other solutions. Goodwill is not amortized but instead is tested for impairment at least annually or more frequently if indicators of impairment are present. For federal income tax purposes, the entire purchase consideration, including goodwill, is deductible over fifteen years. The goodwill recorded from the acquisition of mVisum is attributed to the Product reporting unit.
	The Company incurred $0.2 million of acquisition-related costs that were expensed as incurred. These costs are recorded as general and administrative expenses in the consolidated statement of operations. Additionally, in connection with the acquisition the Company established a retention bonus plan for mVisum with potential additional compensation over a two-year period of approximately $0.5 million, based on achievement of operating objectives and continued employment. Such amounts are not considered part of the purchase consideration and are being recorded as earned as compensation expense. The acquisition did not result in material contributions to revenue or net loss in the consolidated financial statements since the acquisition date. Additionally, pro forma financial information is not provided for consolidated revenue and net loss, since the acquisition was not material to the consolidated financial statements.

Basis of Presentation	'
	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 intercompany balances and transactions have been eliminated. Certain information and disclosures normally included in 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 Annual Report on Form 10-K for the year ended December 31, 2013. The year-end condensed balance sheet data was derived from the Company's 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, 2014 or for any other interim period or any other future year.
Use of Estimates	'
	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, excess and obsolete inventory charges, warranty reserves, 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.
Revenue Recognition	'
	Revenue Recognition
	The Company derives revenue from the sales of communication badges, smartphone application software, perpetual software licenses for enterprise software that is essential to the functionality of the communication badges, software maintenance, extended warranty and professional services. The Company also derives revenue from the sale of perpetual and subscription licenses for software that is not essential to the functionality of the communication badges. The Company's revenue recognition policy has not changed from that described in its Annual Report on Form 10-K for the year ended December 31, 2013.
Lease, Policy	'
	A portion of the Company's sales are made through multi-year lease agreements with customers. When these arrangements are considered sales-type leases, upon delivery of leased products to customers, the Company recognizes revenue for such products in an amount equal to the net present value of the minimum lease payments. Unearned income is recognized as part of product revenue under the effective interest method. The Company recognizes revenue related to executory costs when such executory costs are incurred.
	Proceeds from transfers of sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as financing liabilities.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued new guidance for the gross versus net presentation of unrecognized tax benefits. The FASB concluded that an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss (“NOL”) or other tax credit carryforward when settlement in this manner is available under the tax law. The new guidance was effective for the Company's first quarter of 2014, applied prospectively. Adoption of this standard was not significant to the Company's financial position or results of operations.
	In April 2014, the FASB issued revised guidance for reporting discontinued operations and disclosures of disposals of components of an entity. Under the new guidance, only disposals representing a strategic shift in the entity’s operations and financial results will be presented as discontinued operations. In addition, the new guidance requires certain expanded disclosures about discontinued operations and limited disclosures for a disposal not qualifying for such reporting. The Company’s effective date for these amendments will be the first quarter of 2015, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s financial position or results of operations.
	In May 2014, the FASB together with the International Accounting Standards Board issued converged guidance for revenue recognition that will replace most existing guidance, eliminate industry-specific guidance and provide a unified model for determining how and when revenue from contracts with customers should be recognized. Under the new guidance, an entity 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 standard will also introduce additional disclosures, changes in asset and liability accounting, and changes in gain/loss recognition for asset transfers unrelated to customer transactions.
	The Company’s effective date for this standard will be the first quarter of 2017; no early application is permitted. Two methods of transition are provided: a full retrospective approach, with certain practical expedients allowed, and a cumulative effect method, with balance sheet adjustment as of January 1, 2017. The Company is evaluating the effect the new standard will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the future effect of the standard on its financial position or results of operations.
Fair Value of Fin. Instruments, Policy	'
	Fair Value of Financial Instruments
	The Company’s cash and cash equivalents and short-term investments are carried at their fair values with any differences from their amortized cost recorded in equity as unrealized gains (losses) on marketable securities. As a basis for determining the fair value of its assets and liabilities, the Company established a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. For the six months ended June 30, 2014, there have been no transfers between Level 1 and Level 2 fair value instruments and no transfers in or out of Level 3.
	The Company's money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The fair value of the Company's Level 2 fixed income securities are obtained from independent pricing services, which may use quoted market prices for identical or comparable instruments or model-driven valuations using observable market data or other inputs corroborated by observable market data
Goodwill, Policy	'
	Goodwill
	As of June 30, 2014 and December 31, 2013, the Company had $7.7 million and $5.6 million of goodwill acquired. During the six months ended June 30, 2014, the Company recorded additional goodwill of $2.1 million for the mVisum acquisition (see Note 11, "Business acquisition"). As of June 30, 2014, there were no changes in circumstances indicating that the carrying values of goodwill or acquired intangibles may not be recoverable.
Intangible Assets, Policy	'
	Intangible Assets
	Acquisition-related intangible assets are amortized either straight-line, or over the life of the assets on a basis that resembles the economic benefit of the assets. This yields amortization in the latter case that is higher in earlier periods of the useful life.
Purchase commitments	'
	Non-cancelable Material Commitments
	The Company is required to purchase unused, non-cancelable, non-returnable raw material inventory that was purchased by its contract manufacturers based on committed finished goods orders from the Company, certain long lead-time raw materials based on the Company’s forecast and current work-in-progress materials. As of June 30, 2014 and December 31, 2013, approximately $3.2 million and $3.1 million, respectively, of such inventory was purchased and held by the third-party manufacturers which was subject to these purchase guarantees.
Operating leases	'
	Leases
	The Company leases office space for its headquarters and subsidiaries under non-cancelable operating leases, which will expire between December 2014 and April 2017. The San Jose, California headquarters lease expires on March 31, 2016, with a single three-year extension option at rates approximating the then-fair market value. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid. Facilities rent expense was $0.5 million and $0.5 million for the three months ended June 30, 2014 and June 30, 2013, respectively.
Segment Reporting, Policy	'
	The Company has two operating segments which are both reportable business segments: (i) Product and (ii) Service, both of which are comprised of Vocera’s and its wholly-owned subsidiaries’ results of operations. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer.
	The CODM regularly receives information related to revenue, cost of revenue, and gross profit for each operating segment, and uses this information to assess performance and make resource allocation decisions. All other financial information, including operating expenses and assets, is prepared and reviewed by the CODM on a consolidated basis. Assets are not a measure used to assess the performance of the Company by the CODM; therefore, the Company does not report assets by segment internally or in its financial statements.
