Item 1.   Business 

Overview  

We are 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 U.S. and internationally. Today the significant majority of our business is 
generated from sales of our solutions in the healthcare market, but we are working to expand our sales and marketing efforts to enter and grow in 
other markets. We help our healthcare customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through 
our Communication and Care Experience solutions. These have been installed in more than 1,200 healthcare and non-healthcare organizations 
worldwide.  

The Communication solution, 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.  

At the core of our Communication solution is a patent-protected server software platform that we introduced in 2002. We have significantly 
enhanced and added features and functionality to this solution through ongoing development based on frequent interactions with our customers. Our 
software platform is built upon a scalable architecture and recognizes more than 100 spoken commands. Users can instantly communicate with 
others using the Vocera communication badge or through Vocera Connect and Collaboration Suite client applications for iPhone and Android 
smartphones, as well as through Cisco wireless IP phones. Our solution lets users communicate and collaborate with each other using voice or 
secure text, and unlike other solutions, allows users to reach people by their role, room number or department, without ever knowing a person’s 
name or phone number. The system can also broadcast emergency messages to a single department or a whole company. Our Communication 
solution can be integrated with nurse call, patient monitoring and other clinical systems to immediately and efficiently alert hospital workers to 
patient needs. In applications outside of healthcare, similar integrations are possible, such as the ability to integrate our Communication solution 
with hospitality workflow management solutions to improve guest satisfaction and staff productivity.  

Vocera Care Experience is a hosted, software solution suite that coordinates and streamlines provider-to-patient and provider-to-provider 
communication across the continuum of care.  The solution is used to provide personalized patient instructions and education, to alert and notify 
physicians and caregivers of patients’ changing care plans or status and to track patient satisfaction prior to, during, and following hospitalization.   

Our Experience Innovation Network, our thought leadership consulting division, complements our Vocera Care Experience solutions. It is a 
membership-based program designed to spread the adoption of leading strategies to improve patient and staff experience.

Table of Contents  

Our solutions are deployed in 970 hospitals and healthcare facilities, including large hospital systems, small and medium-sized local hospitals, and 
a small number of clinics, surgery centers and aged-care facilities. Over 1,200 customers, including non-healthcare users, have deployed our 
solutions. We sell our solutions to our healthcare customers primarily through our direct sales force in the United States, with resellers for certain 
U.S. Government business, and through direct sales and select distribution channels in international markets.  

On January 13, 2014, we acquired certain assets of mVisum, Inc., an innovative provider of alarm management technology solutions for health 
systems. This new acquisition specifically addresses communications breakdowns caused by alarm fatigue experienced by healthcare workers in 
critical care facilities. The mVisum solution is expected to align well with our strategic vision of being the leader in integrated, intelligent 
communications solutions for healthcare and other mission-critical environments.  

We were incorporated in Delaware on February 16, 2000. Our corporate headquarters are located at 525 Race Street, San Jose, CA 95126, and our 
main telephone number is (408) 882-5100. We maintain a website at www.vocera.com. The contents of our website are not incorporated into, or 
otherwise to be regarded as part of, this Annual Report on Form 10-K.  

Vocera® is our primary registered trademark in the United States. Other trademarks appearing in this document are the property of their respective

Industry overview  

Vocera provides communication solutions for mobile workers in healthcare, hospitality, energy, education and other industries. Healthcare is our 
largest vertical market. Improving communication among the mobile and highly dispersed healthcare professionals in hospitals is extremely 
important. Hospital communications are typically conducted through disparate systems, including overhead paging, pagers and mobile phones, 
often relying on written records of who is serving in specific roles during a particular shift. These legacy communication methods are inefficient, 
often unreliable, noisy and do not provide “closed loop” communication (in which a caller knows if a message has reached its intended recipient). 
These communication deficiencies can negatively impact patient safety, delay patient care and result in operational inefficiencies.  

Additionally, the increasing focus on improving patients' experience is supported by federal healthcare reform legislation, which incorporates 
financial incentives for hospitals to improve the quality of care and patient satisfaction. A number of non-government organizations, such as The 
Joint Commission, are requiring improvements in patient safety and quality of care. These forces are driving hospitals to invest in technology and 
process improvements to manage their operations more efficiently and to improve safety, quality and cost of care and patient satisfaction. Our 
communication platform helps hospitals increase productivity and reduce costs by streamlining operations, and improves patient and staff 
satisfaction by enabling secure, integrated, and intelligent communication.  

We also serve other vertical industries, including hospitality, nuclear energy and education. In the hospitality industry, our Communication solution 
can be used to increase guest satisfaction and loyalty, as well as staff productivity and responsiveness. In the nuclear energy industry, Vocera can be 
used to instantly connect people and resources to save time and steps, shorten refuel outages, and reduce the potential for worker radiation 
exposure. Schools can leverage our Communication solution to increase security and staff communication, and libraries can use our 
Communication solution to enable their librarians to be more mobile and attentive to their patrons.  

Our strategy  

Our goal is to extend our leadership position as a provider of communication solutions in the healthcare market and expand our communications 
solutions in non-healthcare markets  

Key elements of our strategy include:  

•   Expand our business to new U.S. healthcare customers.     As of December 31, 2013, our solutions were deployed in approximately 11% of 
U.S. hospitals. We believe our unified communication platform can provide significant value to both large and small hospitals. We plan to 
continue to add new customers among hospitals of all sizes. We have structured and incentivized our sales organization to focus on sales to 
new customer sites, particularly within large health systems.  

•   Further penetrate our existing installed customer base.     Typically, our customers initially deploy our Communication solutions in a few 
departments of a hospital and gradually expand to additional departments as they come to fully appreciate the value of our solutions. We 
recognize the significant opportunity to up-sell and cross-sell to our existing customers, including into new hospitals that are part of an existing 
healthcare system customer. Key sales strategies include promoting further adoption of our Communication solution and demonstrating the 
value of our Care Experience solutions to our existing customers. We plan to continue expanding within our existing customers in order to 
grow our revenue and maintain and improve customer experience.

Table of Contents  

•   Extend our technology advantage and create new product solutions.     We intend to continue our investment in research and development to 
enhance the functionality of our communication solutions and further differentiate them from other competing solutions. We plan to invest in 
product upgrades, product line extensions and new solutions to enhance our portfolio, such as our introduction of the Collaboration Suite client 
application for iPhone and Android mobile platforms.  

•   Pursue acquisitions of complementary businesses, technologies and assets.     We have completed five small acquisitions since 2010 to 

expand our solutions offering, demonstrating that we can successfully source, acquire and integrate complementary businesses, technologies 
and assets. We intend to continue to pursue acquisition opportunities that we believe can accelerate the growth of our business.  

•   Grow our international healthcare presence.     Today, in addition to our core U.S. market, we sell primarily into other English-speaking 

markets, including Canada, the United Kingdom, Australia and New Zealand. As of December 31, 2013, our solutions were deployed in over 
125 healthcare facilities outside the United States. We plan both to utilize our direct sales force and leverage channel partners to expand our 
presence in other English-speaking markets and enter non-English speaking countries. We have also introduced localized versions of our 
Communication solution for the French language and for English speakers in Singapore.  

•   Expand our communication solutions in non-healthcare markets.     While our primary focus is on the healthcare market, we believe that our 
communication solutions can also provide value in non-healthcare markets. Our Communication solutions have been deployed at over 200 
customers in markets beyond healthcare including hospitality, energy and other mission critical mobile work environments. Currently, this is 
not a material portion of our revenue, but longer term, we believe these markets could represent potential opportunities for growth.  

Our products, technology and services  

Our solutions include the Vocera Communication System, Vocera Care Experience suite and our Experience Innovation Network, a thought 
leadership collaborative. To complement our solutions, we provide services, support and education to help our customers optimize the benefits of 
our solutions.  

Vocera Communication System  

The Vocera Communication solution is comprised of a unique software platform that connects communication devices, including our hands-free, 
wearable, voice-controlled communication badges, and third-party mobile devices that use our software applications to become part of the Vocera 
system. The system transforms the way mobile workers communicate by enabling them to instantly connect with the right person simply by saying 
the name, function or group name of the person they want to reach, often while remaining at the point-of-care. Our system responds to over 100 
spoken commands.  

Some examples of common commands are shown below.  

Action  

Call by name  

Call a group member  

Spoken commands  
Call John Smith.  

Call an Anesthesiologist.  

Dial a phone number or extension

Components of the Vocera Communication System include:  

•   Software platform.     At the heart of our Vocera Communication System is a patent-protected enterprise-class software platform that runs on 

our customers’ Windows-based servers. The intelligence of our client-server system is contained primarily within our server-software. This 
platform contains an optimized speech recognition engine and call management functionality. In addition, it controls the calling and messaging 
functions of the mobile client devices and maintains profiles for users and groups that enable customization of workflow patterns for each 
customer. Our scalable software platform can support multiple geographic sites and multiple facilities within a healthcare system to help 
clinicians stay connected to the latest status of their patients.  
In addition to the primary system server, our software platform includes usage and diagnostic reporting tools, as well as our telephony software 
to interface to customers’ existing phone systems. Our solution is further embedded into the clinical workflow of the hospital through the 
ability to integrate with over 50 third-party clinical systems, including nurse call, patient monitoring and electronic medical record systems. 
These integrated solutions enable the immediate delivery of alerts to hospital workers, helping to improve patient safety and satisfaction.

Table of Contents  

•   Communication badge .     Our communication badge is a wearable device weighing less than two ounces that operates over customers’ 

industry-standard Wi-Fi networks, the use of which has become increasingly prevalent in hospitals. The badge is worn clipped to a shirt or on a 
lanyard. It can be used to conduct hands-free communication and is the only hands-free device of its kind. It enables instant two-way voice 
conversations without the need to remember a phone number or use a handset. An over-the-air update mechanism seamlessly updates device 
software. Our badge also incorporates automatic diagnostic mechanisms that feed data on wireless network performance back to the software 
platform for reporting and diagnosis of problems. The Vocera B3000 badge, our fourth generation communication badge, offers improved 
durability, a louder speaker for noisy environments and proprietary acoustic noise reduction technology to improve speech recognition by 
eliminating background noise.  

•   Vocera Connect.     Vocera Connect mobile applications allow Vocera customers to enable authorized users to access the voice calling 

capability of our system on third-party mobile devices, including iPhone, Android and other mobile devices. In 2012, we added Cisco wireless 
IP phones to the list of mobile devices we support. When used in a Wi-Fi environment, the Vocera Connect mobile application enables non-
Vocera devices to receive voice communication initiated within the Vocera system, including role-based calls and group broadcasts. Onscreen 
presence information enables users to see the status of other users and instantly connect with particular individuals, functional roles or entire 
groups using voice commands or our click-to-connect functionality.  

•   Vocera Secure Messaging. The Vocera Secure Messaging suite is a secure enterprise messaging and alerting solution that provides smartphone 
users robust, reliable, HIPAA-compliant delivery of critical pages, text, messages, alarms, and alerts. Users can receive and send messages 
from smartphones, and send through a web-based console, or through integrated third-party clinical systems. Our solution delivers text 
messages, alerts and other information, directly to and from smartphones. It is designed to replace paging and unsecure short message service, 
or SMS, systems. Our solution is comprised of an enterprise-grade software platform and client applications that run on iPhone or Android 
devices. The software platform provides the central intelligence, database of users and contacts and monitoring controls that display a real-time 
dashboard of delivery, receipt confirmations and responses.  

•   Vocera Collaboration Suite . The Vocera Collaboration Suite that we recently announced will create a seamless user experience, combining 
the unique calling, texting, alerting and content distribution capabilities of Vocera into one, secure, easy-to-use smartphone application. Key 
features include support for shared and personal Apple IOS and Android devices, ability to call by name, function or group, secure and 
auditable delivery and response reporting for alerts and texts and management of critical alarms and messages delivery through on-call 
scheduling.  

•   Vocera Alarm Management System. As a result of the early 2014 acquisition of mVisum, Inc., we expect to offer in mid-2014 an FDA cleared 
technology that acts as a secondary alarm notification system and provides clinical context, including waveforms, like ECGs, and vital signs, 
offering decision support and insight into the criticality of every alarm. The Alarm Management system uses patented push notification 
technology to connect with and distribute data from almost any hospital alarm-generating device. Configurable dashboards allow users to 
monitor alarms and alarm responses at the floor, nurse and individual bed levels. In addition, the suite of connected care solutions delivers 
patient details to physicians and specialists on their smartphone.  

Vocera Care Experience  
Our Vocera Care Experience solution is a hosted software suite we developed to improve patient and staff experience. Vocera Care Experience 
suite offers caregivers communication solutions that span the entire care continuum - before admission, during treatment and after discharge. This 
patient-centric solution is designed to enable hospitals and health systems to improve care quality and safety, enhance patient experience and 
satisfaction, simplify and automate manual tasks and procedures, improve patient satisfaction scores under the Hospital Consumer Assessment of 
Healthcare Providers and Systems Survey ("HCAHPS"), and otherwise increase revenue and decrease costs.  

Vocera Care Experience includes the following modules:  

•   Good to Go® - Live discharge instructions are recorded, and securely made available for patients, families and other care providers to 

review at any time, using any device.  

•   Care Calls - Streamlines patient follow-up calls and workflows using best practice checklists, risk stratification information, and recorded 

discharge instructions.  

•   Care Rounds - Measures and manages patient experience during a hospital stay in real-time to evaluate gaps in satisfaction and provide 

service recovery interventions.  

•   Performance Analytics - Multi-dimensional dashboards identify gaps in communication, compliance and performance for each patient, 

by department and for the entire enterprise, across the continuum of care.  

•   PCP (Primary Care Physician) Notification - Patient updates can be sent by the hospital staff via text and/or email to primary care 

physicians to keep them up-to-date on their patients' care.  

•   SNF (Skilled Nursing Facility) Communication - Patient discharge notifications along with recorded care instructions can be sent to 

skilled nursing facilities, ensuring safer care transitions.

Sales and marketing  

Sales  

We use a direct sales model to call on hospitals and healthcare systems in the United States, the United Kingdom, Australia and New Zealand. As of 
December 31, 2013, we had 106 sales employees. The sales team is organized to allow us to better serve our customers and to support the different 
elements of our sales strategy. Certain members of the sales team focus on the development of new customer relationships with large integrated 
health systems and government healthcare facilities. Our compensation is structured to incentivize new account development, including higher 
commissions paid for new customers. We supplement our sales organization by utilizing a U.S. government-authorized reseller to facilitate our 
sales to Veterans Administration and Department of Defense healthcare facilities. Sales team members also focus on new customer development 
with smaller systems and individual hospitals. The sales team further includes account managers who focus on service and additional sales to 
existing customers. We enhance our sales efforts by including in our sales staff individuals with nursing backgrounds to address clinical uses with, 
and provide utilization advice to, customers and potential customers. We have also staffed our sales team with system engineers who focus on the 
technical elements of system optimization, particularly wireless, and overall product configuration. In 2013, we staffed a small team of direct sales 
people to focus on developing our non-healthcare business, including hospitality, energy and other mission critical mobile work environments.  

We strive to hire sales people with at least 10 years of experience selling enterprise solutions in healthcare and who have experience selling in 
competitive and complex environments with multiple decision makers. In markets outside the United States, our sales efforts are supplemented by a 
select group of resellers and distributors.  

In addition, as of December 31, 2013, we had 25 employees responsible for sales and services support.  

Marketing  

Our marketing efforts focus on product management, demand generation, sales support and brand management. We believe continuing to increase 
our brand recognition is important for the growth of our business. As of December 31, 2013, we had 22 employees in marketing and business 
development.

Our product roadmap and requirements are driven by both primary and secondary research that is continually validated with current and prospective 
customers. We collect customer feedback through surveys and focus groups, customer visits, a customer advisory board, user forums and 
participation in industry standards organizations. Our customer-centric marketing strategy is key to generating new sales leads as word of mouth 
advertising and testimonials are some of our most valuable marketing tools. A number of our customers have agreed to participate in video 
testimonials, white papers and case studies that validate the efficacy and the financial benefits of our solutions. We have been featured in numerous 
articles and on network television demonstrating increased patient satisfaction, streamlined hospital operations and enhanced employee safety. 
Additionally, we sponsor numerous customer-led webinars to demonstrate customer success and to let prospective customers hear from their peer 
group about the positive impact that our solutions have made on their hospitals. Many of our sales leads come from referrals of existing customers 
or users who have moved from a hospital already using Vocera to a new facility or health system. In 2013, we also developed marketing tools and 
website content to support our non-healthcare business.  

Demand generation is created through high touch activities across multiple platforms including print media, phone, direct mail and e-mail 
campaigns and participation in tradeshows and other industry sponsored events. We use a variety of sales tools with prospective customers 
including collateral, ROI calculators and product videos and presentations.  

Throughout 2013, we received the exclusive endorsement of AHA Solutions, a subsidiary of the American Hospital Association, for our Vocera 
Communication and Care Transition solutions. As part of this endorsement, we are able to participate in customer events sponsored by AHA 
Solutions. Further, we believe hospital customers view this endorsement as a validation of the quality of our solutions.  

Customers  

Our customers include 970 hospitals and other healthcare facilities, of which over 125 are outside of the United States. In addition, we have 
deployed our Vocera Communication solution in over 200 customers in other non-healthcare markets. Our healthcare customers include national 
and international health and hospital systems, large and medium-sized independent and academic hospitals, small hospitals and healthcare facilities, 
and U.S. governmental hospitals and care facilities. Our diverse customer base has very low customer revenue concentration. During 2013, our 
largest end customer represented only1.1% of revenue.  

Currently, we sell primarily into English speaking markets including the United States, Canada, the United Kingdom, Australia, New Zealand and 
Singapore. During 2013 and 2012 , non-U.S. markets represented approximately 10.5% and 10.7% of our revenue, respectively. In addition to 
introduction of a localized French language version of our Vocera Communication solution, we are developing plans to offer our solutions in a 
wider range of international markets including other non-English speaking countries.  

Competition  

We do not believe any single competitor offers an intelligent voice communication system to the healthcare market that allows instant, hands-free 
communication through voice-activated, role-based and activity-based calling using a combination of dedicated, proprietary devices as well as 
accommodating the use of third-party smartphones and other devices.  

At this time, the primary alternative to our system consists of traditional communication methods utilizing wired phones, Wi-Fi in-building phones, 
smartphones, pagers and overhead intercoms.  

The most significant alternative with which we compete for sales in the hospital are in-building wireless telephones. While we compete with the 
providers of these wireless phones in making sales to hospitals, they do not at this time purport to contain the system intelligence and convenience 
of our Communication solution. The market for in-building wireless phones is dominated by large communications companies such as Cisco 
Systems, Ascom and Spectralink.  

We believe that the use of mobile smartphone apps for healthcare and the hospital will continue to expand in our target market and may represent a 
source of competition to our Communication solution. Our Vocera Collaboration Suite smartphone app enables these hospital workers to connect to 
our software platform and participate as users on our Communication system.  

We believe that the primary competitive factors at work in our market include:  

comprehensiveness of the solution and the features provided 

•  
•   product performance and reliability 
•  
•  

the initial cost and ongoing cost of ownership 
customer service and support capabilities

Table of Contents  

We may face increased competition in the future, including competition from large, multinational companies with significant resources. Potential 
competitors may have existing relationships with purchasers of other products and services within the hospital, which may enhance their ability to 
gain a foothold in our market.  

Research and development  

Our continued investment in research and development is critical to our business. We have assembled teams of engineers with expertise in various 
fields, including software, firmware, database design, applications, speech recognition, wireless communication and hardware design. We employ 
research and development personnel in San Jose, California; Knoxville, Tennessee; Toronto, Canada and Bangalore, India. There were 71 full-time 
research and development employees as of December 31, 2013 . We also utilize small teams of contractors in India and Ukraine to assist with 
quality assurance testing and automation, and targeted development efforts. Our research and development expenditures were $14.9 million , $11.6 
million and $9.3 million in 2013 , 2012 and 2011 , respectively.  

Intellectual property  

Our success depends, in part, upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a 
combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections. 

We held, as of December 31, 2013, 18 U.S. patents, including patents on many capabilities of our software platform and communication badge.  
Subsequently, as of January 13, 2014, we acquired through mVisum an additional 7 U.S. patents covering additional healthcare communications 
technologies and had one more patent issued for a total of 26 U.S. Patents. The expiration dates of these patents range from 2018 through 2029. One 
or more utility patents have also been issued in Australia, Canada, India, Japan and the European Patent Office (with validation in Germany, 
France, the United Kingdom and the Netherlands). A European Community design patent has been issued that protects the design in multiple 
European jurisdictions. We have five patent applications pending in the United States, and one or more utility patent applications are pending in 
Canada and at the European Patent Office.  

In addition to the foregoing protections, we generally control access to and use of our proprietary software and other confidential information 
through the use of internal and external controls, including contractual protections with employees, contractors, customers and partners. Our 
software is also protected by U.S. and international copyright laws.  

Our solutions include software developed and owned by us as well as software components we have licensed. These non-exclusive licenses are 
terminable by the licensor for cause. Certain of these licenses are for a contractually specified term and cannot be renewed without the assent of the 
licensor. In the event one or more of these licenses is terminated or is not renewed, we could be required to redesign substantial portions of our 
software in order to incorporate software components from alternative sources. An unplanned redesign of our software could materially and 
adversely affect our business.  

Manufacturing operations and suppliers  

We outsource the manufacturing of our device products to original design manufacturers and a contract manufacturer, SMTC Corporation. Our 
communication badge is currently built in Mexico using custom tools and test equipment owned by us. Initial volumes of new products may be 
manufactured by our contract manufacturer in U.S. facilities. Most of our accessories, including batteries, chargers and attachments, are built by 
original design manufacturers in Asia.  

These manufacturers are responsible for procuring all the components included in our products as specified and approved by us. Some of these 
components are sole-sourced off-the-shelf and some are custom components built exclusively for our products. In the event we are unable to 
procure certain components, we could be required to redesign some of our products in order to incorporate technology from alternative sources. An 
unplanned redesign of our products could materially and adversely affect our business.  

We require our suppliers to perform both incoming and outgoing product inspections. In addition, we perform in-house quality control and ongoing 
reliability testing.  

Employees  

As of December 31, 2013 , we had 383 employees, consisting of 27 in manufacturing and quality operations, 71 in research and development, 153 
in sales and marketing, 81 in services and 51 in general and administrative. None of our employees are covered by a collective bargaining 
agreement or are represented by a labor union. We consider current employee relations to be good.

Backlog  

Our backlog of undelivered orders was $24.4 million and $16.0 million at December 31, 2013 and 2012 , respectively. Of the current backlog, all 
but $3.8 million is expected to be delivered in 2014.  

Government regulations and standards  

Substantially all of our revenue is derived from the healthcare industry. The healthcare industry is highly regulated and is subject to changing 
political, legislative, regulatory and other influences. These factors affect the purchasing practices and operations of healthcare organizations, as 
well as the behavior and attitudes of our users. Healthcare reform has been recently enacted at the federal level. We expect federal and state 
legislatures and agencies to continue to consider programs to reform or revise aspects of the U.S. healthcare system. These programs may contain 
proposals to increase governmental involvement in healthcare or otherwise change the environment in which healthcare industry participants 
operate.  

HIPAA privacy and security standards       

In connection with our healthcare communications business, we handle and have access to personal health information on behalf of our customers. 
Accordingly, in the United States, we are subject to the Health Insurance Portability and Accountability Act of 1996, ("HIPAA"), and its 
implementing regulations, which established uniform standards for certain “covered entities” (healthcare providers engaged in electronic 
transactions, health plans and healthcare clearinghouses) governing the conduct of certain electronic healthcare transactions and protecting the 
security and privacy of protected health information. The American Recovery and Reinvestment Act of 2009 included sweeping expansion of 
HIPAA’s privacy and security standards as reflected in the Health Information Technology for Economic and Clinical Health Act, ("HITECH"). 
Among other things, the new law makes certain HIPAA privacy and security standards directly applicable to “business associates” - independent 
contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a 
covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and 
possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the 
federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. Most of our customers are covered entities 
under HIPAA and, to the extent that we handle personal health information on their behalf, we are their “business associates” and are subject to 
HIPAA and associated contractual obligations, as well as comparable state privacy and security laws.  

In addition, we are subject to privacy and security regulations in other jurisdictions. For example, the EU adopted the Data Protection Directive or 
"DPD" (officially Directive 95/46/EC ), imposing strict regulations and establishing a series of requirements regarding the storage of personally 
identifiable information on computers or recorded on other electronic media. This has been implemented by all EU member states through national 
laws. DPD provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data privacy 
protection when receiving personal data from any of the EU member states. Similarly, Canada’s Personal Information and Protection of Electronic 
Documents Act provides Canadian residents with privacy protections in regard to transactions with businesses and organizations in the private 
sector and sets out ground rules for how private sector organizations may collect, use and disclose personal information in the course of commercial 
activities.  

These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure of personal health 
information with which we must comply, and subject us to material liability and other adverse impacts to our business in the event we fail to do so. 
These include, without limitation, civil fines, criminal sanctions in certain circumstances, contractual liability to our customer, and damage to our 
brand and reputation. We endeavor to mitigate these risks through measures we believe to be appropriate for the specific circumstances, including 
storing personal data under our control on password-protected systems in secure facilities, counseling our customers as to best practices in using our 
solutions, and encrypting such information.  

Medical device regulation  

The U.S. Food and Drug Administration ("FDA") regulates certain products, including software-based products, as “medical devices” based, in 
part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform properly. We have 
concluded that our communication products are general-purpose communication devices not subject to FDA regulation. However, either the 
FDA could disagree with our conclusion or changes in our product or the FDA’s evolving regulations could lead to the imposition of medical 
device regulation on our products. In this event, we would be subject to extensive regulatory requirements, including the expense of compliance 
with Medical Device Reporting and Quality System regulation and the potential of liability for failure to comply, and we could be required to 
obtain 510(k) clearance or premarket approval of our products from the FDA prior to commercial distribution. Some of the new products acquired 
as a result of the mVisum acquisition are regulated by the FDA as Class II medical devices under applicable law and FDA regulations, including 
being subject to the new 2.3% excise tax under the Affordable Care Act. Class II devices are devices  

10  

 
 
Table of Contents  

classified by the FDA as posing a moderate to high risk and therefore subject to both “general controls” and “special controls”, as such terms are 
defined in the Food, Drug and Cosmetics Act. Further, for other products we could become subject to the 2.3% excise tax if the FDA were to 
determine in the future that they constitute medical devices.  

Electrical standards and FCC regulations  

Our products emit radio frequency energy in the 2.4 GHz spectrum band for which licensing by U.S. and other regulatory authorities is not 
required, provided that the products conform to certain requirements, e.g., maximum power output and tolerance of interference from other devices 
sharing that spectrum band. We subject our products to testing by independent testing laboratories for compliance with the relevant standards issued 
by various U.S. and international bodies, including the European Union (with respect to the “CE” mark), the International Electrotechnical 
Commission, the Australian Communications and Media Authority, Underwriters Laboratories and CSA International.

Information about segment and geographic revenue is set forth in Note 9 of the Notes to Consolidated Financial Statements under Item 8 of this 
Annual Report on Form 10-K. In addition, financial information regarding our operations, assets and liabilities, including our total net revenue and 
net income (loss) for the years ended December 31, 2013 , 2012 and 2011 , and our total assets as of December 31, 2013 and 2012 , is included in 
our Consolidated Financial Statements under Item 8 of this Annual Report on Form 10-K.

Item 1A.   Risk Factors 

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together 
with all of the other information set forth in this Annual Report on Form 10-K. Our business, financial condition, results of operations or future 
prospects could be materially and adversely harmed if any of the following risks, or other risks or uncertainties that are not yet identified or that we 
currently believe are immaterial, actually occur. The trading price of our common stock could decline due to any of these risks or uncertainties, 
and, as a result, you may lose all or part of your investment.  

Risks related to our business and industry  

We have incurred significant losses in the past, and may experience losses in the future. As a result, our business may be harmed and our stock 
price could decline.  

12  

 
 
 
 
 
 
 
   
 
 
 
Table of Contents  

We have incurred significant losses in the past and reported a net loss of $10.5 million for the year ended December 31, 2013 . As of December 31, 
2013 , we had an accumulated deficit of $64.4 million . If we cannot achieve profitability in future periods, our business may be harmed and our 
stock price could further decline.  

Our ability to be profitable in the future depends upon continued demand for our communication solutions from existing and new customers. 
Further market adoption of our solutions, including increased penetration within our existing customers, depends upon our ability to improve 
patient safety and satisfaction and increase hospital efficiency and productivity, and to bring value to customers outside of healthcare. Additionally, 
further adoption of our solutions in non-healthcare markets depends on our ability to modify our products to successfully respond to the challenges 
in those markets and our sales efforts to reach the customers in those markets. In addition, our profitability will be affected by, among other things, 
our ability to execute on our business strategy, the timing and size of orders, the pricing and costs of our solutions, macroeconomic conditions 
affecting the health care industry and the extent to which we invest in sales and marketing, research and development and general and 
administrative resources.  

We depend on sales of our Vocera Communication solution in the healthcare market for substantially all of our revenue, and any decrease in 
its sales would harm our business.  

To date, substantially all of our revenue has been derived from sales of our Vocera Communication solution to the healthcare market and, in 
particular, hospitals. Any decrease in revenue from sales of our Vocera Communication solution would harm our business. Sales of our Vocera 
Communication solution to the healthcare market accounted for 91% and 92% of our revenue for the years ended December 31, 2013 and 2012 , 
respectively. In addition, we obtained a significant portion of these sales from existing hospital customers. We anticipate that sales of our Vocera 
Communication solution will represent a significant portion of our revenue for the foreseeable future. While we are evaluating new solutions for 
non-healthcare markets, we may not be successful in applying our technology in any of these markets, or in selling our solutions to customers in 
these markets. We do not anticipate that sales of our Vocera Communication solution in non-healthcare markets will represent a significant portion 
of our revenue for the foreseeable future.  

Our success depends in part upon the deployment of our Vocera Communication solution by new hospital customers, the expansion and upgrade of 
our solution at existing customers, and our ability to continue to provide on a timely basis cost-effective solutions that meet the requirements of our 
hospital customers. Our Vocera Communication solution requires a substantial upfront investment by customers. Typically, our hospital customers 
initially deploy our solution for specific users in specific departments before expanding our solution into other departments or for other users. The 
cost of the initial deployment depends on the number of users and departments involved, the size and age of the hospital and the condition of the 
existing wireless infrastructure, if any, within the hospital.  

Even if hospital personnel determine that our Vocera Communication solution provides compelling benefits over their existing communications 
methods, their hospitals may not have, or may not be willing to spend, the resources necessary to install and maintain wireless infrastructure to 
initially deploy and support our solution or expand our solution to other departments or users. Hospitals are currently facing significant budget 
constraints, ever increasing demands from a growing number of patients and impediments to obtaining reimbursements for their service. In 
addition, hospitals, including both governmental and non-governmental customers, are experiencing budgeting issues due to the ongoing effects of 
and uncertainty around the continuing impact of federal government sequestration on Medicare reimbursement rates and the federal budget, as well 
as continuing changes in the implementation of the Patient Protection and Affordable Care Act of 2010 ("ACA") and other healthcare reform 
legislation. As a consequence, we may continue to experience a slowdown and deferral of orders for our Vocera Communication solution that could 
negatively impact our sales. We believe hospitals are currently allocating funds for capital and infrastructure improvements to benefit from 
electronic medical records incentives and, for compliance with ICD-10 diagnosis coding requirements, which may impact their ability to purchase 
and deploy our solution. We might not be able to sustain or increase our revenue from sales of our Vocera Communication solution, or achieve the 
growth rates that we envision, if hospitals continue to face significant budgetary constraints and reduce their spending on communications systems.  

Our sales cycle can be lengthy and unpredictable, which may cause our revenue and operating results to fluctuate significantly.  

Our sales cycles can be lengthy and unpredictable. Our sales efforts involve educating our customers about the use and benefits of our solutions, 
including the technical capabilities of our solutions and the potential cost savings and productivity gains achievable by deploying them. Customers 
typically undertake a significant evaluation process, which frequently involves not only our solutions but also their existing communications 
methods and those of our competitors, and can result in a lengthy sales cycle of nine to twelve months or more. We spend substantial time, effort 
and money in our sales efforts without any assurance that our efforts will produce any sales. In addition, purchases of our solutions are frequently 
subject to budget  

13  

 
 
 
 
 
 
 
 
 
Table of Contents  

constraints, multiple approvals, and unplanned administrative, processing and other delays. For example, we experienced elongated sales cycles due 
to uncertainty surrounding healthcare reform and lower hospital admission trends in 2013. At this time, hospitals in the U.S. face significant 
uncertainty over the continuing impact of federal government sequestration, the country’s debt ceiling and federal budget, and continuing changes 
in the implementation and deadlines for compliance with the ACA and other healthcare reform legislation, as well as potential future statutes and 
rulemaking.  

If our business does not grow as we expect, or we are not able to manage our growth effectively, our operating results will suffer.  

We have experienced significant growth in our revenues and operations in the past. Our growth has placed, and may continue to place, strains on 
our management systems, infrastructure and other resources. We plan to hire additional direct sales and marketing personnel domestically and 
internationally, acquire complementary businesses, technologies or assets, and increase our investment in research and development. Our future 
operating results depend to a large extent on our ability to successfully implement these plans and manage our anticipated expansion. To do so 
successfully we must, among other things:  

•   manage our expenses in line with our operating plans and current business environment; 
•   maintain and enhance our operational, financial and management controls, reporting systems and procedures; 
•  
•   manage operations in multiple locations and time zones; and 
•   develop and deliver new solutions and enhancements to existing solutions efficiently and reliably. 

integrate acquired businesses, technologies or assets; 

We expect to incur costs associated with the investments made to support our growth before the anticipated benefits or the returns are realized, if at 
all. If we are unable to grow our business as expected or manage our future growth effectively, we may not be able to take advantage of market 
opportunities or develop new solutions or enhancements to existing solutions. We may also fail to satisfy customer requirements, maintain quality, 
execute our business plan or respond to competitive pressures, which could result in lower revenue and a decline in the share price of our common 
stock.  

Our revenue and operating results have fluctuated, and are likely to continue to fluctuate, which may make our quarterly results difficult to 
predict, cause us to miss analyst expectations and cause the price of our common stock to decline.  

Our operating results may be difficult to predict, even in the near term, and are likely to fluctuate as a result of a variety of factors, many of which 
are outside of our control.  

Comparisons of our revenue and operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an 
indication of our future performance. Each of the following factors, among others, could cause our operating results to fluctuate from quarter to 
quarter:  

•  
•  

the financial health of our healthcare customers and budgetary constraints on their ability to upgrade their communications; 
changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for 
their services;  

the procurement and deployment cycles of our healthcare customers and the length of our sales cycles; 

•   our ability to expand our sales and marketing operations; 
•  
•   variations in the amount of orders booked in a prior quarter but not delivered until later quarters; 
•   our mix of solutions and pricing, including discounts by us or our competitors; 
•   our ability to expand into non-healthcare markets; 
•   our ability to forecast demand and manage lead times for the manufacture of our solutions; and 
•   our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance. 

Developments in the healthcare industry and governing regulations could negatively affect our business.  

Substantially all of our revenue is derived from customers in the healthcare industry, in particular, hospitals. The healthcare industry is highly 
regulated and is subject to changing political, legislative, regulatory and other influences. Developments generally affecting the healthcare industry, 
including new regulations or new interpretations of existing regulations, could adversely affect spending on information technology and capital 
equipment by reducing funding, changing healthcare pricing or delivery or creating impediments for obtaining healthcare reimbursements, which 
together with declining admission trends,  could cause our sales to decline and negatively impact our business. For example, the profit margins of 
our hospital customers are modest, and pending changes in reimbursement for healthcare costs may reduce the overall solvency of our customers or 
cause further deterioration in their financial or business condition.

Since 2009, three significant bills were signed into law that impact the U.S. healthcare system.  Those bills include The Health Information 
Technology for Economic and Clinical Health Act, enacted under Title XIII of the American Recovery and Reinvestment Act of 2009 ("HITECH 
Act"), the ACA, and the Health Care and Education Reconciliation Act of 2010. Together, these acts drive substantive changes over several years to 
the operating processes, reimbursements and rules governing the U.S. healthcare system. The actual end effect of these laws on the marketplace is 
not yet fully understood.   

We believe that our healthcare customers are unsure of the impact that a number of the elements of those acts will have on their business, and 
cannot predict the timing and requirements of the final rules issued by the U.S. Department of Health and Human Services ("HHS") for these 
statutes, making managing their business operations more difficult.  Further, as has been experienced since 2010, as these final rules are created by 
HHS, a number of aspects of the acts have been interpreted, modified or delayed. For example, sudden changes in the rules for individuals buying 
insurance through state or federal health insurance exchanges, and individual and employer mandates to have and offer insurance coverage, have 
challenged hospitals’ abilities to forecast patient utilization and revenues, and to set operational plans and budget accordingly.  

Federal budget activities also impact our customers.  The federal budget sequestration, which went into effect in March 2013, automatically cut 
Medicare reimbursement rates and cut federal department budgets, including at the Department of Defense, which also operates hospitals that are 
prospective customers. We believe sequestration had a significant impact on our customers and our business in 2013. As part of the Bipartisan 
Budget Act of 2013, signed into law on December 26, 2013, the Medicare reimbursement rate cut established in the March 2013 sequester was 
maintained and extended, although the cuts to Department of Defense and its hospitals were lifted. We further believe that it is likely that additional 
legislative changes and rulemaking by HHS will continue. In addition, many state governments are changing or expanding their healthcare laws, 
adding additional complexity to understanding the potential impacts.  

We are unable to predict the full impact of these new and changing rules on our hospital customers and others in the healthcare industry.  Impacts of 
these rules could materially affect our customers’ ability to budget for or purchase our products. The healthcare industry has changed significantly 
in recent years and we expect that significant changes will continue to occur. We cannot assure you that the markets for our solutions will continue 
to exist at current levels or that we will have adequate technical, financial and marketing resources to react to changes in those markets.  

If we fail to increase market awareness of our brand and solutions, and expand our sales and marketing operations, our business could be 
harmed.  

We intend to continue to add personnel and resources in sales and marketing as we focus on expanding awareness of our brand and solutions and 
capitalize on sales opportunities with new and existing customers. Our efforts to improve sales of our solutions will result in an increase in our sales 
and marketing expense and general and administrative expense, and these efforts may not be successful. Some newly hired sales and marketing 
personnel may subsequently be determined to be unproductive and have to be replaced, resulting in operational and sales delays and incremental 
costs. If we are unable to significantly increase the awareness of our brand and solutions or effectively manage the costs associated with these 
efforts, our business, financial condition and operating results could be harmed.  

We primarily compete in the rapidly evolving and competitive healthcare market, and if we fail to effectively respond to competitive pressures, 
our business and operating results could be harmed.  

We believe that at this time the primary competition for our Vocera Communication solution consists of traditional methods using wired phones, 
pagers and overhead intercoms. While we believe that our system is superior to these legacy methods, our solution requires a significant 
infrastructure investment by a hospital and many hospitals may not recognize the value of implementing our solution.  

Manufacturers and distributors of product categories such as cellular phones, smartphone applications, pagers, mobile radios and in-building 
wireless telephones attempt to sell their products to hospitals as components of an overall communication system. Of these product categories, in-
building wireless telephones represent the most significant competition for the sale of our solution. The market for in-building wireless phones is 
dominated by communications companies such as Cisco Systems, Ascom and Spectralink. In addition, the proliferation of smartphones and related 
applications may represent a new category of competitive offerings.  

While we do not have a directly comparable competitor that provides a richly featured Vocera Communication system for the healthcare market, we 
could face such competition in the future. Potential competitors in the healthcare or communications markets include large, multinational 
companies with significantly more resources to dedicate to product development and sales and marketing. These companies may have existing 
relationships within the hospital, which may enhance their ability to gain a  

15  

 
 
 
 
 
 
 
 
 
 
 
Table of Contents  

foothold in our market. Customers may prefer to purchase a more highly integrated or bundled solution from a single provider or an existing 
supplier rather than a new supplier, regardless of performance or features. Accordingly, if we fail to effectively respond to competitive pressures, 
we could experience pricing pressure, reduced profit margins, higher sales and marketing expenses, lower revenue and the loss of market share, any 
of which would harm our business, operating results or financial condition.  

If we fail to offer high-quality services and support for any of our solutions, our ability to sell those solutions will be harmed.  

Our ability to sell our Vocera Communication or Care Experience solutions is dependent upon our professional services and technical support teams 
providing high-quality services and support. Our professional services team assists our customers with their wireless infrastructure assessment, 
clinical workflow design, communication solution configuration, training and project management during the pre-deployment and deployment 
stages. Once our solutions are deployed within a customer’s facility, the customer typically depends on our technical support team to help resolve 
technical issues, assist in optimizing the use of our solutions and facilitate adoption of new functionality. If we do not effectively assist our 
customers in deploying our solutions, succeed in helping our customers quickly resolve technical and other post-deployment issues, or provide 
effective ongoing support services, our ability to expand the use of our solutions with existing customers and to sell our solutions to new customers 
will be harmed. If deployment of our solutions is unsatisfactory, as has been the case with certain third-party deployments in the past, we may incur 
significant costs to attain and sustain customer satisfaction. As we rapidly hire new services and support personnel, we may inadvertently hire 
underperforming people who will have to be replaced, or fail to effectively train such employees, leading in some instances to slower growth, 
additional costs and poor customer relations. In addition, the failure of channel partners to provide high-quality services and support in markets 
outside the United States could also harm sales of our solutions.  

The implementation of our new enterprise resource planning system could disrupt our business and adversely affect our financial results.  
In the fourth quarter of 2012, we initiated a multi-year project to upgrade certain key internal systems and processes, including our enterprise 
resource planning (“ERP”) system and company-wide human resources management system. The first phase "go live" date was completed in the 
third quarter of 2013. We have invested, and will continue to invest, significant capital and human resources in the design and implementation of 
these systems and processes. Any disruptions or delays in the design and implementation of the new systems or processes, particularly any 
disruptions or delays that impact our operations, could adversely affect our ability to process customer orders, ship products, provide service and 
support to our customers, bill and track our customers, fulfill contractual obligations, record and transfer information in a timely and accurate 
manner, file SEC reports in a timely manner, or otherwise run our business. Even if we do not encounter these adverse effects, the design and 
implementation of these new systems and processes may be much more costly than we anticipated. If we are unable to successfully design and 
implement these new systems and processes as planned, or if the implementation of these systems and processes is more costly than anticipated, our 
business, financial condition, and results of operations could be negatively impacted.  

We depend on a number of sole source and limited source suppliers, and if we are unable to source our components from them, our business 
and operating results could be harmed.  

We depend on sole and limited source suppliers for several hardware components of our Vocera Communication solution, including our batteries 
and integrated circuits. We purchase inventory generally through individual purchase orders. Any of these suppliers could cease production of our 
components, cease to provide the necessary levels of support for our use of their components, experience capacity constraints, material shortages, 
work stoppages, financial difficulties, cost increases or other reductions or disruptions in output, cease operations or be acquired by, or enter into 
exclusive arrangements with, a competitor. These suppliers typically rely on purchase orders rather than long-term contracts with their suppliers, 
and as a result, even if available, the supplier may not be able to secure sufficient materials at reasonable prices or of acceptable quality to build our 
components in a timely manner. Any of these circumstances could cause interruptions or delays in the delivery of our solutions to our customers, 
and this may force us to seek components from alternative sources, which may not have the required specifications, or be available in time to meet 
demand or on commercially reasonable terms, if at all. Any of these circumstances may also force us to redesign our solutions if a component 
becomes unavailable in order to incorporate a component from an alternative source.  

Our solutions incorporate multiple software components obtained from licensors on a non-exclusive basis, such as voice recognition software, 
software supporting the runtime execution of our software platform, and database and reporting software. Our license agreements can be terminated 
for cause. In many cases, these license agreements specify a limited term and are only renewable beyond that term with the consent of the licensor. 
If a licensor terminates a license agreement for cause, objects  

16  

 
 
 
 
 
 
 
 
Table of Contents  

to its renewal or conditions renewal on modified terms and conditions, we may be unable to obtain licenses for equivalent software components on 
reasonable terms and conditions, including licensing fees, warranties or protection from infringement claims. Some licensors may discontinue 
licensing their software to us or support of the software version used in our solutions. In such circumstances, we may need to redesign our solutions 
at substantial cost to incorporate alternative software components or be subject to higher royalty costs. Any of these circumstances could adversely 
affect the cost and availability of our solutions.  

Third-party licensors generally require us to incorporate specific license terms and conditions in our agreements with our customers. If we are 
alleged to have failed to incorporate these license terms and conditions, we may be subject to claims by these licensors, incur significant legal costs 
defending ourselves against such claims and, if such claims are successful, be subject to termination of licenses, monetary damages, or an 
injunction against the continued distribution of one or more of our solutions.  

Because we depend upon a contract manufacturer, our operations could be harmed and we could lose sales if we encounter problems with this 
manufacturer.  

We do not have internal manufacturing capabilities and rely upon a contract manufacturer, SMTC Corporation, ("SMTC"), to produce the primary 
hardware component of our Vocera Communication solution. We have entered into a manufacturing agreement with SMTC that is terminable by 
either party with advance notice and that may also be terminated for a material uncured breach. We also rely on original design manufacturers, or 
ODMs, to produce accessories, including batteries, chargers and attachments. Any of these suppliers could cease production of our components, 
cease to provide the necessary levels of support for our use of their components, experience capacity constraints, material shortages, work 
stoppages, financial difficulties, cost increases or other reductions or disruptions in output, cease operations or be acquired by, or enter into 
exclusive arrangements with, a competitor. If SMTC or an ODM is unable or unwilling to continue manufacturing components of our solutions in 
the volumes that we require, fails to meet our quality specifications or significantly increases its prices, we may not be able to deliver our solutions 
to our customers with the quantities, quality and performance that they expect in a timely manner. As a result, we could lose sales and our operating 
results could be harmed.  

SMTC or ODMs may experience problems that could impact the quantity and quality of components of our Vocera Communication solution, 
including disruptions in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, component or material shortages 
and cost increases. SMTC and these ODMs generally rely on purchase orders rather than long-term contracts with their suppliers, and as a result, 
may not be able to secure sufficient components or other materials at reasonable prices or of acceptable quality to build components of our solutions 
in a timely manner. The majority of the components of our Vocera Communication solution are manufactured in Asia or Mexico and adverse 
changes in political or economic circumstances in those locations could also disrupt our supply and quality of components of our solutions.  

Companies occasionally encounter unexpected difficulties in ramping up production of new products, and we may experience such difficulties with 
future generations of our products. SMTC and our ODMs also manufacture products for other companies. Generally, our orders represent a 
relatively small percentage of the overall orders received by SMTC and these ODMs from their customers; therefore, fulfilling our orders may not 
be a priority in the event SMTC or an ODM is constrained in its ability to fulfill all of its customer obligations. In addition, if SMTC or an ODM is 
unable or unwilling to continue manufacturing components of our solutions, we may have to identify one or more alternative manufacturers. The 
process of identifying and qualifying a new contract manufacturer or ODM can be time consuming, and we may not be able to substitute suitable 
alternative manufacturers in a timely manner or at an acceptable cost. Additionally, transitioning to a new manufacturer may cause us to incur 
additional costs and delays if the new manufacturer has difficulty manufacturing components of our solutions to our specifications or quality 
standards.  

If we fail to forecast our manufacturing requirements accurately, or fail to properly manage our inventory with our contract manufacturer, we 
could incur additional costs and experience manufacturing delays, which can adversely affect our operating results.  

We place orders with our contract manufacturer, SMTC, and we and SMTC place orders with suppliers based on forecasts of customer demand. 
Because of our international low cost sourcing strategy, our lead times are long and cause substantially more risk to forecasting accuracy than 
would result were lead times shorter. Our forecasts are based on multiple assumptions, each of which may introduce errors into our estimates 
affecting our ability to meet our customers' demands for our solutions. We also may face additional forecasting challenges due to product 
transitions in the components of our solutions, or to our suppliers discontinuing production of materials and subcomponents required for our 
solutions. If demand for our solutions increases significantly, we may not be able to meet demand on a timely basis, and we may need to expend a 
significant amount of time working with our customers to allocate limited supply and maintain positive customer relations, or we may incur 
additional costs in order to source additional materials and subcomponents to produce components of our solutions or to expedite the  

17  

 
 
 
 
 
 
 
Table of Contents  

manufacture and delivery of additional inventory. If we underestimate customer demand, our contract manufacturer may have inadequate materials 
and subcomponents on hand to produce components of our solutions, which could result in manufacturing interruptions, shipment delays, deferral 
or loss of revenue, and damage to our customer relationships. Conversely, if we overestimate customer demand, we and SMTC may purchase more 
inventory than required for actual customer orders, resulting in excess or obsolete inventory, thereby increasing our costs and harming our operating 
results.  

If hospitals do not have and are not willing to install, upgrade and maintain the wireless infrastructure required to effectively operate our 
Vocera Communication solution, then they may experience technical problems or not purchase our solution at all.  

The effectiveness of our Vocera Communication solution depends upon the quality and compatibility of the communications environment that our 
healthcare customers maintain. Our solutions require voice-grade wireless, or Wi-Fi, installed through large enterprise environments, which can 
vary from hospital to hospital and from department to department within a hospital. Many hospitals have not installed a voice-grade wireless 
infrastructure. If potential customers do not have a wireless network that can properly and fully interoperate with our Vocera Communication 
solution, then such a network must be installed, or an existing Wi-Fi network must be upgraded or modified, for example, by adding access points 
in stairwells, for our Vocera Communication solution to be fully functional. The additional cost of installing or upgrading a Wi-Fi network may 
dissuade potential customers from installing our solution. Furthermore, if changes to a customer's physical or information technology environment 
cause integration issues or degrade the effectiveness of our solution, or if the customer fails to upgrade or maintain its environment as may be 
required for software releases or updates or to ensure our solution's effectiveness, the customer may not be able to fully utilize our solution or may 
experience technical problems, or these changes may impact the performance of other wireless equipment being used. If such circumstances arise, 
prospective customers may not purchase or existing customers may not expand their use of or deploy upgraded versions of our Vocera 
Communication solution, thereby harming our business and operating results.  

If we fail to achieve and maintain certification for certain U.S. federal standards, our sales to U.S. government customers will suffer.  

We believe that a significant opportunity exists to sell our products to healthcare facilities in the Veterans Administration and Department of 
Defense, or DoD. These customers require independent certification of compliance with particular requirements relating to encryption, security, 
interoperability and scalability. These requirements include compliance with Federal Information Processing Standard, or FIPS, 140-2 and, as to 
DoD facilities, certification by the Joint Interoperability and Test Command of DoD and under the DoD Information Assurance Certification and 
Accreditation Process. We have received certification under certain of these standards for a military-specific configuration of the Vocera 
communication solution incorporating the B2000 badge. We are carrying out activities intended to achieve additional certifications, including 
certifications applicable to the B3000 badge, expected in the first half of 2014, and future products as well. A failure on our part to comply in a 
timely manner with these requirements, or to maintain certification, both as to current products and as to new product versions, could adversely 
impact our revenue.  

Our expanded efforts to sell our communications solutions in non-healthcare markets may not be successful.  

Our primary focus has been on selling our communications solutions to the healthcare market, with other markets addressed only opportunistically.  
We recently expanded our sales efforts to customers outside the healthcare markets, including hospitality, energy and other mobile work 
environments. We may not be successful in further penetrating the non-healthcare markets upon which we are initially focusing, or other new 
markets. To date, our Vocera Communication solution has been deployed in over 200 customers in non-healthcare markets. Total revenue from 
non-healthcare customers accounted for 3% of our revenue for both the years ended December 31, 2013 and 2012 . If we cannot maintain these 
customers by providing communications solutions that meet their requirements, if we cannot successfully expand our communications solutions in 
non-healthcare markets, or if our solutions are adopted more slowly than we anticipate, we may not obtain significant revenue from these markets. 
We may experience challenges as we expand in non-healthcare markets, including pricing pressure on our solutions and technical issues as we 
adapt our solutions for the requirements of new markets. Our communications solutions also may not contain the functionality required by these 
non-healthcare markets or may not sufficiently differentiate us from competing solutions such that customers can justify deploying our solutions.  

If we fail to successfully develop and introduce new solutions and features to existing solutions, our revenue, operating results and reputation 
could suffer.  

Our success depends, in part, upon our ability to develop and introduce new solutions and features to existing solutions that meet existing and new 
customer requirements. We may not be able to develop and introduce new solutions or features on a  

18  

 
 
 
 
 
 
 
 
 
 
Table of Contents  

timely basis or in response to customers’ changing requirements, or that sufficiently differentiate us from competing solutions such that customers 
can justify deploying our solutions. We may experience technical problems and additional costs as we introduce new features to our software 
platform, deploy future models of our wireless badges and integrate new solutions with existing customer clinical systems and workflows. In 
addition, we may face technical difficulties as we expand into non-English speaking countries and incorporate non-English speech recognition 
capabilities into our Vocera Communication solution. We also may incur substantial costs or delays in the manufacture of any additional new 
products or models as we seek to optimize production methods and processes at our contract manufacturer. In addition, we expect that we will at 
least initially achieve lower gross margins on new models, while endeavoring to reduce manufacturing costs over time. If any of these problems 
were to arise, our revenue, operating results and reputation could suffer.  

If we do not achieve the anticipated strategic or financial benefits from our acquisitions or if we cannot successfully integrate them, our 
business and operating results could be harmed.  

We have acquired, and in the future may acquire, complementary businesses, technologies or assets that we believe to be strategic, such as our 
recent mVisum acquisition. We may not achieve the anticipated strategic or financial benefits, or be successful in integrating any acquired 
businesses, technologies or assets. If we cannot effectively integrate our Vocera Communication solution with our Secure Messaging and Care 
Experience solutions and successfully market and sell these solutions, we may not achieve market acceptance for, or significant revenue from, these 
new solutions.  

Integrating newly acquired businesses, technologies and assets could strain our resources, could be expensive and time consuming, and might not 
be successful. Our recent acquisition exposes us and we will be further exposed, if we acquire or invest in additional businesses, technologies or 
assets, to a number of risks, including that we may:  

•  
•  

•  

experience technical issues as we integrate acquired businesses, technologies or assets into our existing communications solutions; 
encounter difficulties leveraging our existing sales and marketing organizations, and direct sales channels, to increase our revenue from 
acquired businesses, technologies or assets;  
find that the acquisition does not further our business strategy, we overpaid for the acquisition or the economic conditions underlying our 
acquisition decision have changed;  

•   have difficulty retaining the key personnel of acquired businesses; 
•  

suffer disruption to our ongoing business and diversion of our management's attention as a result of transition or integration issues and the 
challenges of managing geographically or culturally diverse enterprises; and  
experience unforeseen and significant problems or liabilities associated with quality, technology and legal contingencies relating to the 
acquisition, such as intellectual property or employment matters.  

•  

In addition, from time to time we may enter into negotiations for acquisitions that are not ultimately consummated. These negotiations could result 
in significant diversion of management time, as well as substantial out-of-pocket costs. If we were to proceed with one or more significant 
acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash. To the extent we issue 
shares of capital stock or other rights to purchase capital stock, including options and warrants, the ownership of existing stockholders would be 
diluted. In addition, acquisitions may result in the incurrence of debt, contingent liabilities, large write-offs, or other unanticipated costs, events or 
circumstances, any of which could harm our operating results.  

We generally recognize revenue from maintenance and support contracts over the contract term, and changes in sales may not be immediately 
reflected in our operating results.  

We generally recognize revenue from our customer maintenance and support contracts ratably over the contract term, which is typically 12 months, 
in some cases subject to an early termination right. Revenue from our maintenance and support contracts accounted for 31% and 26% of our 
revenue for the years ended December 31, 2013 and 2012 , respectively. A portion of the revenue we report in each quarter is derived from the 
recognition of deferred revenue relating to maintenance and support contracts entered into during previous quarters. Consequently, a decline in new 
or renewed maintenance and support by our customers in any one quarter may not be immediately reflected in our revenue for that quarter. Such a 
decline, however, will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market 
acceptance of our services and potential changes in our rate of renewals may not be fully reflected in our operating results until future periods.  

Our success depends upon our ability to attract, integrate and retain key personnel, and our failure to do so could harm our ability to grow our 
business.  

19  

 
 
 
 
 
 
 
 
 
 
Table of Contents  

Our success depends, in part, on the continuing services of our senior management and other key personnel, and our ability to continue to attract, 
integrate and retain highly skilled personnel, particularly in engineering, sales and marketing. Competition for highly skilled personnel is intense, 
particularly in the Silicon Valley where our headquarters are located. If we fail to attract, integrate and retain key personnel, our ability to grow our 
business could be harmed.  

The members of our senior management and other key personnel are at-will employees, and may terminate their employment at any time without 
notice. If they terminate their employment, we may not be able to find qualified individuals to replace them on a timely basis or at all and our senior 
management may need to divert their attention from other aspects of our business. Former employees may also become employees of a competitor. 
We may also have to pay additional compensation to attract and retain key personnel. We also anticipate hiring additional engineering, marketing 
and sales, and services personnel to grow our business. Often, significant amounts of time and resources are required to train these personnel. We 
may incur significant costs to attract, integrate and retain them, and we may lose them to a competitor or another company before we realize the 
benefit of our investments in them.  

Our international operations subject us, and may increasingly subject us in the future, to operational, financial, economic and political risks 
abroad.  

Although we derive a relatively small portion of our revenue from customers outside the United States, we believe that non-U.S. customers could 
represent an increasing share of our revenue in the future. During the years ended December 31, 2013 and 2012 , we obtained 10.5% and 10.7% of 
our revenue, respectively, from customers outside of the United States, including Canada, the United Kingdom, Australia, the Republic of Ireland 
and New Zealand. Accordingly, we are subject to risks and challenges that we would not otherwise face if we conducted our business solely in the 
United States, including:  

challenges incorporating non-English speech recognition capabilities into our solutions as we expand into non-English speaking jurisdictions; 

•  
•   difficulties integrating our solutions with wireless infrastructures with which we do not have experience; 
•   difficulties integrating local dialing plans and applicable PBX standards; 
•  
•   difficulties in staffing and managing personnel and resellers; 
•  

challenges associated with delivering support, training and documentation in several languages; 

the need to comply with a wide variety of foreign laws and regulations, including increasingly stringent data privacy regulations, requirements 
for export controls for encryption technology, employment laws, changes in tax laws and tax audits by government agencies;  

•   political and economic instability in, or foreign conflicts that involve or affect, the countries of our customers; 
•   difficulties in collecting accounts receivable and longer accounts receivable payment cycles; 
•  
•  
•  

exposure to competitors who are more familiar with local markets; 
limited or unfavorable intellectual property protection in some countries; and 
currency exchange rate fluctuations, which could affect the price of our solutions relative to locally produced solutions. 

Any of these factors could harm our existing international business, impair our ability to expand into international markets or harm our operating 
results.  

Our solutions are highly complex and may contain software or hardware errors that could harm our reputation and operating results.  

Our solutions incorporates complex technology, is deployed in a variety of complex hospital environments and must interoperate with many 
different types of devices and hospital systems. While we test the components of our solutions for defects and errors prior to release, we or our 
customers may not discover a defect or error until after we have deployed our solution, integrated it into the hospital environment and our customer 
has commenced general use of the solution. In addition, our solutions in some cases are integrated with hardware and software offered by 
“middleware” vendors in order to interoperate with nurse call systems, device alarms and other hospital systems. If we cannot successfully integrate 
our solution with these vendors as needed or if any hardware or software of these vendors contains any defect or error, then our solution may not 
perform as designed, or may exhibit a defect or error.  

Any defects or errors in, or which are attributed to, our solutions, could result in:  

•   delayed market acceptance of our affected solutions; 
loss of revenue or delay in revenue recognition; 
•  
•  
loss of customers or inability to attract new customers; 
•   diversion of engineering or other resources for remedying the defect or error; 

20  

 
 
 
 
 
 
 
 
 
 
Table of Contents  

•   damage to our brand and reputation; 
•  
•  

increased service and warranty costs; and 
legal actions by our customers and hospital patients, including product liability claims. 

If any of these occur, our operating results and reputation could be harmed.  

We face potential liability related to the privacy and security of personal information collected through our solutions.  

In connection with our healthcare communications business, we handle and have access to personal health information subject in the United States 
to the Health Insurance Portability and Accountability Act of 1996, or HIPAA, the Health Information Technology for Economic and Clinical 
Health Act of 2009, or HITECH, regulations issued pursuant to these statutes, state privacy and security laws and regulations, and associated 
contractual obligations as a “business associate” of healthcare providers. These statutes, regulations and contractual obligations impose numerous 
requirements regarding the use and disclosure of personal health information with which we must comply. Our failure to accurately anticipate the 
application or interpretation of these statutes, regulations and contractual obligations as we develop our solutions, a failure by us to comply with 
their requirements (e.g., evolving encryption and security requirements) or an allegation that defects in our products have resulted in noncompliance 
by our customers could create material civil and/or criminal liability for us, resulting in adverse publicity and negatively affecting our business.  

In addition, the use and disclosure of personal health information is subject to regulation in other jurisdictions in which we do business or expect to 
do business in the future. Those jurisdictions may attempt to apply such laws extraterritorially or through treaties or other arrangements with U.S. 
governmental entities. We might unintentionally violate such laws, such laws may be modified and new laws may be enacted in the future which 
may increase the chance that we violate them. Any such developments, or developments stemming from enactment or modification of other laws, or 
the failure by us to comply with their requirements or to accurately anticipate the application or interpretation of these laws could create material 
liability to us, result in adverse publicity and negatively affect our business.  

For example, the European Union, or EU, adopted the Data Protection Directive, or DPD, imposing strict regulations and establishing a series of 
requirements regarding the storage of personally identifiable information on computers or recorded on other electronic media. This has been 
implemented by all EU member states through national laws. DPD provides for specific regulations requiring all non-EU countries doing business 
with EU member states to provide adequate data privacy protection when receiving personal data from any of the EU member states. Similarly, 
Canada’s Personal Information and Protection of Electronic Documents Act provides Canadian residents with privacy protections in regard to 
transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use 
and disclose personal information in the course of commercial activities. A finding that we have failed to comply with applicable laws and 
regulations regarding the collection, use and disclosure of personal information could create liability for us, result in adverse publicity and 
negatively affect our business.  

Any legislation or regulation in the area of privacy and security of personal information could affect the way we operate our services and could 
harm our business. The costs of compliance with, and the other burdens imposed by, these and other laws or regulatory actions may prevent us from 
selling our solutions or increase the costs associated with selling our solutions, and may affect our ability to invest in or jointly develop solutions in 
the United States and in foreign jurisdictions. Further, we cannot assure you that our privacy and security policies and practices will be found 
sufficient to protect us from liability or adverse publicity relating to the privacy and security of personal information.  

The failure of our equipment lease customers to pay us under leasing agreements with them that we do not sell to third party lease finance 
companies could harm our revenue and operating results.  

In 2012 we began offering our badges and related hardware accessories to our customers through multi-year equipment lease agreements. In 
connection with each sale, we recognize product-related revenue at the net present value of the lease payment stream once our obligations related to 
such sale have been met. We plan to sell the bulk of these leases, including the related accounts receivables, to third party lease finance companies 
on a non-recourse basis. We will have to retain unsold leases in-house, which will expose us to the creditworthiness of such equipment lease 
customers over the lease term. For the leases that we retain in-house, our ability to collect payments from a customer or to recognize revenue for the 
sale could be impaired if the customer fails to meet its obligations to us such as in the case of its bankruptcy filing or deterioration in its financial 
position, or has other creditworthiness issues, any of which could harm our revenue and operating results.  

Our use of open source and non-commercial software components could impose risks and limitations on our ability to commercialize our 
solutions.  

21  

 
 
 
 
 
 
 
 
 
Table of Contents  

Our solutions contain software modules licensed under open source and other types of non-commercial licenses, including the GNU Public License, 
the GNU Lesser Public License, the Apache License and others. We also may incorporate open source and other licensed software into our 
solutions in the future. Use and distribution of such software may entail greater risks than use of third-party commercial software, as licenses of 
these types generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Some of 
these licenses require the release of our proprietary source code to the public if we combine our proprietary software with open source software in 
certain manners. This could allow competitors to create similar products with lower development effort and time and ultimately result in a loss of 
sales for us.  

The terms of many open source and other non-commercial licenses have not been judicially interpreted and there is a risk that such licenses could 
be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions. In such event, in 
order to continue offering our solutions, we could be required to seek licenses from alternative licensors, which may not be available on a 
commercially reasonable basis or at all, to re-engineer our solutions or to discontinue the sale of our solutions in the event we cannot obtain a 
license or re-engineer our solutions on a timely basis, any of which could harm our business and operating results. In addition, if an owner of 
licensed software were to allege that we had not complied with the conditions of the corresponding license agreement, we could incur significant 
legal costs defending ourselves against such allegations. In the event such claims were successful, we could be subject to significant damages, be 
required to disclose our source code, or be enjoined from the distribution of our solutions.  

Claims of intellectual property infringement could harm our business.  

Vigorous protection and pursuit of intellectual property rights has resulted in protracted and expensive litigation for many companies in our 
industry. Although claims of this kind have not materially affected our business to date, there can be no assurance of the absence of such claims in 
the future. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant 
amounts of management time, result in the diversion of significant operational resources, or require us to enter into royalty or licensing agreements, 
any of which could harm our business and operating results.  

Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, and we cannot be certain 
that we will be successful in defending ourselves against intellectual property claims. In addition, we currently have a limited portfolio of issued 
patents compared to many other industry participants, and therefore may not be able to effectively utilize our intellectual property portfolio to assert 
defenses or counterclaims in response to patent infringement claims or litigation brought against us by third parties. Further, litigation may involve 
patent holding companies or other adverse patent owners who have no relevant products and against whom our potential patents may provide little 
or no deterrence.  

Many potential litigants have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend 
claims that may be brought against them. Furthermore, a successful claimant could secure a judgment that requires us to pay substantial damages or 
prevents us from distributing certain solutions or performing certain services. We might also be required to seek a license and pay royalties for the 
use of such intellectual property, which may not be available on commercially acceptable terms or at all. Alternatively, we may be required to 
develop non-infringing technology, which could require significant effort and expense and may ultimately not be successful.  

If we are unable to protect our intellectual property rights, our competitive position could be harmed or we could be required to incur 
significant expenses to enforce our rights.  

Our success depends, in part, on our ability to protect our proprietary technology. We protect our proprietary technology through patent, copyright, 
trade secret and trademark laws in the United States and similar laws in other countries. We also protect our proprietary technology through 
licensing agreements, nondisclosure agreements and other contractual provisions. These protections may not be available in all cases or may be 
inadequate to prevent our competitors from copying, reverse engineering or otherwise obtaining and using our technology, proprietary rights or 
solutions in an unauthorized manner. The laws of some foreign countries may not be as protective of intellectual property rights as those in the 
United States, and mechanisms for enforcement of intellectual property rights may be inadequate. In addition, third parties may seek to challenge, 
invalidate or circumvent our patents, trademarks, copyrights and trade secrets, or applications for any of the foregoing. Our competitors may 
independently develop technologies that are substantially equivalent, or superior, to our technology or design around our proprietary rights. In each 
case, our ability to compete could be significantly impaired.  

To prevent unauthorized use of our intellectual property rights, it may be necessary to prosecute actions for infringement or misappropriation of our 
proprietary rights. Any such action could result in significant costs and diversion of our resources and  

22  

 
 
 
 
 
 
 
 
 
 
Table of Contents  

management's attention, and there can be no assurance that we will be successful in such action. Furthermore, many of our current and potential 
competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than us. Accordingly, despite our 
efforts, we may not be able to prevent third parties from infringing or misappropriating our intellectual property. While we plan to continue to 
protect our intellectual property with, among other things, patent protection, there can be no assurance that:  

current or future U.S. or foreign patent applications will be approved; 

•  
•   our issued patents will protect our intellectual property and not be held invalid or unenforceable if challenged by third parties; 
•   we will succeed in protecting our technology adequately in all key jurisdictions in which we or our competitors operate; or 
•   others will not independently develop similar or competing products or methods or design around any patents that may be issued to us. 

Our failure to obtain patents with claims of a scope necessary to cover our technology, or the invalidation of our patents, or our inability to protect 
any of our intellectual property, may weaken our competitive position and harm our business and operating results. We might be required to spend 
significant resources to monitor and protect our intellectual property rights. We may initiate claims or litigation against third parties for 
infringement of our proprietary rights or to establish the validity of our proprietary rights. Any litigation, whether or not it is resolved in our favor, 
could result in significant expense to us and divert the efforts of our technical and management personnel, which may harm our business, operating 
results and financial condition.  

Some of our solutions are and others could become subject to regulation by the U.S. Food and Drug Administration or similar foreign agencies, 
which could increase our operating costs.  

We provide products that may become subject to regulation by the FDA, and similar agencies in other countries, or the jurisdiction of these 
agencies could be expanded in the future to include our solutions. The FDA regulates certain products, including software-based products, as 
“medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform 
properly. Although we have concluded that our wireless badge is a general-purpose communications device not subject to FDA regulation, the FDA 
could disagree with our conclusion, or changes in our solutions or the FDA’s evolving regulation could lead to FDA regulation of our solutions. If 
these products were deemed to be medical devices, they would be subject to the 2.3% excise tax under the Affordable Care Act. Canada and many 
other countries in which we sell or may sell our solutions could also have similar regulations applicable to our solutions, some of which may be 
subject to change or interpretation. We may incur substantial operating costs if we are required to register our solutions or components of our 
solutions as regulated medical devices under U.S. or foreign regulations, obtain premarket approval from the FDA or foreign regulatory agencies, 
and satisfy the extensive reporting requirements. In addition, failure to comply with these regulations could result in enforcement actions and 
monetary penalties. A clinical communications product acquired from mVisum, Inc. is regulated by the FDA as a Class II medical device.  

Product liability or other liability claims could cause us to incur significant costs, adversely affect the sales of our solutions and harm our 
reputation.  

Our solutions are utilized by healthcare professionals and others in the course of providing patient care. It is possible that patients, family members, 
physicians, nurses or others may allege we are responsible for harm to patients or healthcare professionals due to defects in, the malfunction of, the 
characteristics of, or the operation of, our solutions. Any such allegations could harm our reputation and ability to sell our solutions.  

Components of our solutions utilizing Wi-Fi also emit radio frequency, or RF, energy. RF emissions have been alleged, in connection with cellular 
phones, to have adverse health consequences. While these components of our solutions comply with guidelines applicable to such emissions, some 
may allege that these components of our solutions cause adverse health consequences or applicable guidelines may change making these 
components of our solutions non-compliant. Regulatory agencies in the United States and other countries in which we do or plan to do business 
may implement regulations concerning RF emissions standards. In addition, healthcare professionals have alleged and may allege in the future that 
magnets in our badges may emit electromagnetic radiation or otherwise interfere with implanted medical or other devices. Any such allegations or 
non-compliance, or any regulatory developments, including any changes affecting the transmission of radio signals, could negatively impact the 
sales of our solutions, require costly modifications to our solutions and harm our reputation.  

Although our customer agreements contain terms and conditions, including disclaimers of liability, that are intended to reduce or eliminate our 
potential liability, we could be required to spend significant amounts of management time and resources to defend ourselves against product 
liability, tort, warranty or other claims. If any such claims were to prevail, we could be forced  

23  

 
 
 
 
 
 
 
 
 
Table of Contents  

to pay damages, comply with injunctions or stop distributing our solutions. Even if potential claims do not result in liability to us, investigating and 
defending against these claims could be expensive and time consuming and could divert management's attention away from our business. We 
maintain general liability insurance coverage, including coverage for errors and omissions; however, this coverage may not be sufficient to cover 
large claims against us or otherwise continue to be available on acceptable terms. Further, the insurer could attempt to disclaim coverage as to any 
particular claim.  

Our business is subject to the risks of earthquakes, fire, floods and other natural catastrophic events, and to interruption by man-made 
problems such as power disruptions or terrorism.  

Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity, and many critical components of our 
solutions are sourced in Asia and Mexico, regions known to suffer natural disasters. A significant natural disaster, such as an earthquake, fire or a 
flood, occurring at our headquarters, our other facilities or where our contract manufacturer or its suppliers are located, could harm our business, 
operating results and financial condition. In addition, acts of terrorism could cause disruptions in our business, the businesses of our customers and 
suppliers, or the economy as a whole. We also rely on information technology systems to communicate among our workforce located worldwide, 
and in particular, our senior management, general and administrative, and research and development activities that are coordinated with our 
corporate headquarters in the San Francisco Bay Area. Any disruption to our internal communications, whether caused by a natural disaster or by 
man-made problems, such as power disruptions, in the San Francisco Bay Area, Asia or Mexico could delay our research and development efforts, 
cause delays or cancellations of customer orders or delay deployment of our solutions, which could harm our business, operating results and 
financial condition.  

We may require additional capital to support our business growth, and such capital may not be available.  

We intend to continue to make investments to support business growth and may require additional funds to respond to business challenges, which 
include the need to develop new solutions or enhance existing solutions, enhance our operating infrastructure, expand our sales and marketing 
capabilities, expand into non-healthcare markets, and acquire complementary businesses, technologies or assets. Accordingly, we may need to 
engage in equity or debt financing to secure funds. Equity and debt financing, however, might not be available when needed or, if available, might 
not be available on terms satisfactory to us. If we raise additional funds through equity financing, our stockholders may experience dilution. Debt 
financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. If we are unable to obtain adequate 
financing or financing on terms satisfactory to us, our ability to continue to support our business growth and to respond to business challenges could 
be significantly limited as we may have to delay, reduce the scope of or eliminate some or all of our initiatives, which could harm our operating 
results.  

As an “emerging growth company” under the JOBS Act, we are permitted to, and may, rely on exemptions from certain disclosure and 
governance requirements.  

As an “emerging growth company” under the Jumpstart Our Business Startups Act, or JOBS Act, we are permitted to, and may, rely on exemptions 
from certain disclosure and governance requirements. For example, for so long as we are an emerging growth company, which can last, at most, 
until the first fiscal year following the fifth anniversary of our initial public offering, we will not be required to:  

•   have our independent registered public accounting firm report on our internal control over financial reporting pursuant to Section 404(b) of the 

•  

Sarbanes-Oxley Act;  
comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm 
rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements;  

•   provide the “compensation discussion and analysis” and certain compensation tables for our named executive officers in our Form 10-K or 

annual proxy statement; and  
submit certain executive compensation matters to stockholder advisory votes, such as “say on pay” and “say on frequency.”

•  

We could be an emerging growth company for up to five years. However, if the market value of our common stock that is held by non-affiliates 
exceeds $700 million as of June 30th of any year, we could cease to be an “emerging growth company” as of the following December 31st. This 
threshold was not reached for June 30, 2013. After exceeding the threshold, as of each fiscal year end, our independent registered public accounting 
firm will be required to evaluate and report on our internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act. While 
management has established plans to accommodate the additional assessment and attestation procedures and related costs of Section 404(b) 
compliance, we may incur additional costs or require additional management time to comply with Section 404(b) in a timely manner.  

24  

 
 
 
 
 
 
Table of Contents  

If we do not maintain effective internal control over financial reporting or disclosure controls and procedures in the future, the accuracy and 
timeliness of our financial reporting may be adversely affected.  

The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and 
disclosure controls and procedures quarterly. In particular, beginning with the year ending on December 31, 2013, we must obtain confidence in our 
internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting as 
required by Section 404 of the Sarbanes-Oxley Act. To the extent we find a material weakness or other deficiency in our internal control over 
financial reporting, the accuracy and timeliness of our financial reporting may be adversely affected.  

Multiple negative consequences could ensue if a material weakness in our internal control over financial reporting is identified in the future, or we 
are not able to comply with the requirements of Section 404 in a timely manner or we do not maintain effective controls. For example, our reported 
financial results could be materially misstated or could be restated, we could receive an adverse opinion regarding our controls from our 
independent registered public accounting firm (once such opinion is required under the Sarbanes-Oxley Act), or we could be subject to 
investigations or sanctions by regulatory authorities. All of these outcomes would require additional financial and management resources, and the 
market price of our stock could decline.  

We will continue to incur increased costs as a result of operating as a public company and our management will have to devote substantial time 
to public company compliance obligations.  

As a public company, we will continue to incur substantial legal, accounting and other expenses that we did not incur as a private company. We will 
continue to incur substantial expenses even though we as an “emerging growth company” may rely upon the disclosure and governance exemptions 
under the JOBS Act. The Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and our stock 
exchange, impose various requirements on public companies, including changes in corporate governance practices. Our management and other 
personnel will need to devote a substantial amount of time to these compliance requirements and any new requirements that the Dodd-Frank Wall 
Street Reform and Consumer Protection Act of 2010 may impose on public companies. Moreover, these rules and regulations, along with 
compliance with accounting principles and regulatory interpretations of such principles, as amended by the JOBS Act, have increased and will 
continue to increase our legal, accounting and financial compliance costs and have made and will continue to make some activities more time-
consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and 
officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantial costs to maintain the same or 
similar coverage.  

We face risks related to securities litigation that could result in significant legal expenses and settlement or damage awards.  

We are currently, and may in the future become, subject to claims and litigation alleging violations of the securities laws or other related claims, 
which could harm our business and require us to incur significant costs. For example, on August 1, 2013 and August 21, 2013, purported securities 
class actions were filed in the United States District Court for the Northern District of California against us and certain of our officers, our board of 
directors, a former director and the underwriters for our initial public offering. The suits purport to allege claims for allegedly misleading statements 
in the registration statement for our initial public offering and in subsequent communications regarding our business and financial results. 
Regardless of the outcome, these matters or future litigation may require significant attention from management and could result in significant legal 
expenses, settlement costs or damage awards that could have a material impact on our financial position, results of operations and cash flows.  

Compliance with the SEC's new rule for disclosures on sourcing of "conflict minerals" may be time consuming and costly and could adversely 
affect our reputation.  

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC has adopted a new rule that applies to companies that 
use certain minerals and metals, known as conflict minerals, in their products, including certain products manufactured for them by third parties. 
The new rule will require companies that use conflict minerals in the production of their products to  conduct diligence as to whether or not such 
minerals originate from the Democratic Republic of Congo and adjoining countries and to file certain information with the SEC about the use of 
these minerals. We will incur additional costs to comply with the due diligence and disclosure requirements.  In addition, depending upon our 
findings, or our inability to make reliable findings, about the source of any conflict minerals that we use, our reputation could be harmed. The first 
conflict minerals report is due June 2, 2014. To date, we have not incurred any material incremental costs, but we may in the future.  

Risks related to our common stock  

The market price of our common stock may be volatile, and your investment in our stock could suffer a decline in value.  

25  

 
 
 
 
 
 
 
Table of Contents  

There has been significant volatility in the market price and trading volume of equity securities, which is often unrelated or disproportionate to the 
financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our 
common stock. The market price of our common stock could fluctuate significantly in response to the factors described in this “Risk Factors” 
section and elsewhere in this Form 10-K and other factors, many of which are beyond our control, including:  

•  
•  
•  

•  

actual or anticipated variation in anticipated operating results of us or our competitors; 
the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections; 
announcements by us or our competitors of new solutions, new or terminated significant contracts, commercial relationships or capital 
commitments;  
failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or 
our failure to meet these estimates or the expectations of investors;  

commencement of, or our involvement in, litigation; 
announced or completed acquisitions of businesses, technologies or assets by us or our competitor; 
changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular; 

•   developments or disputes concerning our intellectual property or other proprietary rights; 
•  
•  
•  
•   price and volume fluctuations attributable to inconsistent trading volume levels of our common stock; 
•   our public float relative to the total number of shares of our common stock that are issued and outstanding; 
•   price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole; 
•  
•  
•   unfavorable economic conditions and slow or negative growth of our markets; and 
•   other events or factors, including those resulting from war or incidents of terrorism. 

rumors and market speculation involving us or other companies in our industry; 
any major change in our management; 

If securities or industry analysts issue an adverse or misleading opinion regarding our stock or do not publish research or reports about our 
business, our stock price could decline.  

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us and our 
business. We do not control these analysts or the content and opinions included in their reports. The price of our common stock could decline if one 
or more analysts downgrade our common stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our 
business. If one or more analysts cease coverage of our company or fail to regularly publish reports about our company, we could lose visibility in 
the financial market, which in turn could cause our stock price to decline. Further, securities or industry analysts may elect not to provide research 
coverage of our common stock and such lack of research coverage may adversely affect the market price of our common stock.  

The concentration of our capital stock ownership with insiders will likely limit your ability to influence corporate matters.  

Our executive officers, directors, current 5% or greater stockholders and entities affiliated with any of them together beneficially own 
approximately 52% of our common stock outstanding as of December 31, 2013 . These stockholders, if they act together, will have significant 
influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, and 
may take actions that may not be in the best interests of our other stockholders. This concentration of ownership could also limit stockholders’ 
ability to influence corporate matters. Accordingly, corporate actions might be taken even if other stockholders, including you, oppose them, or may 
not be taken even if other stockholders view them as in the best interests of our stockholders. This concentration of ownership may have the effect 
of delaying or preventing a change of control of our company, may make the approval of certain transactions difficult or impossible without the 
support of these stockholders and might adversely affect the market price of our common stock.  

Our stock price could decline due to the substantial number of outstanding shares of our common stock that are available for sale on the public 
market.  

All of our outstanding shares are freely tradable without restrictions or further registration under the federal securities laws, except for shares held 
by directors, executive officers and other affiliates which are subject to volume limitations under Rule 144 of the Securities Act of 1933 and various 
vesting agreements.  If the holders of substantial amounts of such freely tradable shares sell, or indicate an intention to sell, the trading price of our 
common stock could decline.  Additional shares subject to outstanding warrants, outstanding options and RSUs, or reserved for future issuance 
under our equity incentive and employee stock purchase plans, could also become available for sale in the public market to the extent permitted by 
the provisions of various vesting agreements and Rules 144 and 701 under the Securities Act.

We have never paid cash dividends on our capital stock, and we do not anticipate paying any dividends in the foreseeable future.  

We have never paid cash dividends on any of our capital stock and currently intend to retain our future earnings to fund the development and 
growth of our business. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.  

Our charter documents and Delaware law could discourage, delay or prevent a change of control of our company or change in our 
management that stockholders consider favorable and cause our stock price to decline.  

Certain provisions of our restated certificate of incorporation and restated bylaws and Delaware law could discourage, delay or prevent a change of 
control of our company or change in our management that the stockholders of our company consider favorable. These provisions:  

•  

authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares and 
to discourage a takeover attempt;  

•   prohibit stockholder action by written consent, requiring all stockholder actions to be taken at a meeting of stockholders; 
•  

establish advance notice procedures for nominating candidates to our board of directors or proposing matters that can be acted upon by 
stockholders at stockholder meetings;  
•  
limit the ability of our stockholders to call special meetings of stockholders; 
•   prohibit stockholders from cumulating their votes for the election of directors; 
•   permit newly created directorships resulting from an increase in the authorized number of directors or vacancies on our board of directors to be 

filled only by majority vote of our remaining directors, even if less than a quorum is then in office;  

•   provide that our board of directors is expressly authorized to make, alter or repeal our bylaws;

On August 1, 2013 a purported securities class action entitled Brado v. Vocera Communications Inc., et al . was filed in the United States District 
Court for the Northern District of California against us and certain of our officers, our board of directors, a former director and the underwriters for 
our 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 our initial public offering and in subsequent communications regarding our 
business and financial results. The suits are purportedly brought on behalf of purchasers of our 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 we anticipate that the plaintiffs will file an amended 
consolidated complaint. No response to the current complaints is due at this time.  

Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of this matter. We are unable at this time to 
determine whether the outcome of the litigation would have a material impact on our results of operations, financial condition or cash flow. We 
have not established any reserve for any potential liability relating to this lawsuit.  

From time to time, we 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.

determination to pay dividends on our common stock will be at the discretion of our board of directors and will depend upon, among other factors, 
our financial condition, operating results, current and anticipated cash needs, plans for expansion and other factors that our board of directors may 
deem relevant.

Item 7.   Management's Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial 
statements and related notes included in Item 8, “Financial Statements and Supplementary Data” included in this Annual Report on Form 10-K. 
This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions, such as statements of our plans, 
objectives, expectations and intentions. The cautionary statements made in this Annual Report on Form 10-K should be read as applying to all 
related forward-looking statements wherever they appear in this Annual Report on Form 10-K. Our actual results may differ materially from those 
anticipated in these forward-looking statements as a result of many factors, including but not limited to those set forth under Item 1A, “Risk 
factors” and elsewhere in this Annual Report on Form 10-K.  

Business overview  

We are 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 U.S. and internationally. Today the significant majority of our business is 
generated from sales of our solutions in the healthcare market, but we are working to expand our sales and marketing efforts to enter and grow in 
other markets. We help our healthcare customers improve patient safety and satisfaction, and increase hospital efficiency and productivity through 
our Communication and Care Experience solutions. These have been installed in more than 1,200 healthcare and non-healthcare organizations 
worldwide.  

We outsource the manufacturing of our products. Our outsourced manufacturing model allows us to scale our business without the significant 
capital investment and on-going expenses required to establish and maintain manufacturing operations. We work closely with our contract 
manufacturer, SMTC Corporation, and key suppliers to manage the procurement, quality and cost of components. We seek to maintain an optimal 
level of finished goods inventory to meet our forecast sales and unanticipated shifts in sales volume and mix.  

We primarily sell products and maintenance services directly to end users. To date, substantially all of our revenue has been derived from sales of 
our Vocera Communication solution, including product maintenance and related services. Revenue grew 1.5% to $102.5 million in 2013 from 
$101.0 million in 2012 , and our 2012 revenue grew 27.0% from $79.5 million in 2011 . For the year ended December 31, 2013 we recorded a net 
loss of $10.5 million . For the year ended December 31, 2012 , we recorded a net income of $2.9 million and net income attributable to common 
stockholders of $1.5 million .  

Our diverse customer base ranges from large hospital systems to small local hospitals, as well as other healthcare facilities and customers in non-
healthcare markets. We are not reliant on any one customer. For 2013 , our largest end customer represented only 1.1% of revenue. While we have 
international customers in other English speaking countries such as Canada, the United Kingdom and Australia, most of our customers are located 
in the United States. International customers represented 10.5% and 10.7% of our revenue in 2013 and in 2012 , respectively. We are developing 
plans to expand our presence in other English speaking markets and enter non-English speaking markets.  

2013 was a challenging year for our U.S. hospital customers. Many hospitals responded to the federal budget sequestration in March 2013 by 
freezing or cutting operating and departmental budgets.  

These U.S. hospital industry trends affected our ability to expand the adoption of our solutions within existing customers, which has traditionally 
been a key factor in our revenue growth. At the same time, however, we experienced 19% growth in new customers. New customers most often buy 
our solutions from capital expenditure budgets, which were less affected than departmental operating budgets. This helped offset the reduced 
expansion of the use of our solutions within existing customers.  

Federal hospitals, which include Veterans Administration (VA) and Department of Defense (DoD), were differently affected by these healthcare 
reform trends. VA hospitals were specifically excluded from the sequester budget cutbacks, and we saw strong growth in VA contracts in the year. 
The DoD, however, was a primary target of the sequester cuts, which caused active military hospitals to cut spending budgets.  

We experienced strong growth from international hospitals in 2013, although it is a small portion of our current revenues, as is our non-healthcare 
business in hospitality, energy and other industries with mobile workers.  

Entering 2014, the rules, dates and actual impact of critical parts of the Affordable Care Act and other healthcare reform legislation remain 
uncertain based on the significant changes in 2013. We believe many U.S. hospitals are maintaining their cautious outlook for revenue and 
budgeting into 2014. At the same time, we further believe that productivity, safety and patient satisfaction are top priorities for many hospitals. 
With the new customer demand we experienced in 2013 for our core Vocera Communication System, plus several new products being introduced in 
2014, we believe we are well positioned to help hospitals achieve those objectives.

Components of operating results  

Revenue.     We generate revenue from the sale of products and services. As discussed further in the section titled “Critical accounting policies and 
estimates—Revenue recognition and deferred revenue” below, revenue is recognized when persuasive evidence of an arrangement exists, delivery 
has occurred, the price is fixed or determinable and collection is reasonably assured.  

Revenue is comprised of the following:  

•   Product.     Our solutions include both hardware and software. We refer to hardware revenue as device revenue, which includes revenue from 

sales of our communication badges, badge accessories, including batteries, battery chargers, lanyards, clips and other ancillary badge 
components. Software revenue is derived primarily from the sale of perpetual licenses to our Vocera Communication System. We derive 
additional software revenue from the sale of term licenses or services provided, which can be renewed on a subscription basis. Product revenue 
is generally recognized upon shipment of hardware and perpetual licenses and, in the case of term licenses or subscription services, ratably over 
the applicable term.  

•   Service.     We receive service revenue from sales of software maintenance, extended hardware warranties and professional services. Software 

maintenance is typically invoiced annually in advance, recorded as deferred revenue, and recognized as revenue ratably over the service period. 
Our professional services revenue is based on both time and materials, and fixed price contracts, and is recognized as the services are provided. 
Extended warranties are invoiced in advance, recorded as deferred revenue, and recognized ratably over the extended warranty period.  

Cost of revenue.     Cost of revenue is comprised of the following:  

•   Cost of product.     Cost of product is comprised primarily of materials costs, software license costs, write-offs for excess and obsolete 

inventory, warranty, and manufacturing overhead costs for test engineering, material requirements planning and our shipping and receiving 
functions. These overhead costs also include facilities, equipment depreciation, amortization of developed technology and stock-based 
compensation expenses. We expect material costs to vary with the product life cycle of our devices.  
Cost of service.     Cost of service is comprised primarily of employee wages, benefits and related personnel expenses of our technical support 
team, our professional consulting personnel and our training teams. Cost of service also includes facility and information technology costs. We 
expect our cost of service will increase as we continue to invest in support services to meet the needs of our customer base.  

Operating expenses.     Operating expenses are comprised of the following:  

•   Research and development.     Research and development expenses consist primarily of employee wages, benefits and related personnel 

expenses, hardware materials, and consultant fees and expenses related to the design, development, testing and enhancements of our solutions. 
We intend to continue to invest in improving the functionality of our solutions and the development of new solutions. As a result, we expect 
research and development expense to increase for the foreseeable future.  

•   Sales and marketing.     Sales and marketing expenses consist primarily of employee wages, benefits and related personnel expenses, as well as 
trade shows, marketing programs and collateral and public relations programs. Sales commissions are earned when an order is received from a 
customer, and as a result, in some cases these commissions are expensed in an earlier period than the period in which the related revenue is 
recognized. Historically, our bookings have tended to peak in the fourth quarter of each year driving higher sales commissions, and to be 
lowest in the first quarter. We intend to continue to expand our direct sales force, invest in sales support functions and new marketing programs 
for the foreseeable future, and accordingly, expect sales and marketing expenses to increase.  

•   General and administrative.     General and administrative expenses consist primarily of employee wages, benefits and related personnel 
expenses, consulting, accounting fees, legal fees and other general corporate expenses. We expect general and administrative expense to 
increase for the foreseeable future due to the significant costs we expect to incur as we continue to build and maintain the infrastructure 
necessary to comply with the regulatory requirements of being a public company and as we add personnel to support our growth.  

Interest income, interest expense and other income (expense), net.  

•  

Interest income.     Interest income consists primarily of interest income earned on our cash, cash equivalent and short-term investment 
balances. Our interest income will vary each reporting period depending on our average cash, cash equivalent and short-term investment 
balances during the period and market interest rates.

Table of Contents  

•  

Interest expense .    Interest expense includes interest expense related to debt and financing obligations resulting from our credit facility and 
security agreement, which was paid off in full on April 3, 2012. Since then interest expense has been immaterial, but could potentially fluctuate 
in the future with changes in our borrowings.  

•   Other income (expense), net.     Other income (expense), net consists primarily of income from a stipend for market research regarding the 
industry in which our company operates that we provided to a market research firm, and the change in the fair value of our convertible 
preferred stock warrants. Our convertible preferred stock warrants were classified as liabilities and, as such, were marked-to-market at each 
balance sheet date with the corresponding gain or loss from the adjustment recorded as other income (expense), net. Upon the consummation of 
our initial public offering, on April 2, 2012, these warrants converted into warrants to purchase common stock and are no longer marked-to-
market. Other income (expense), net also includes any foreign exchange gains and losses.  

Provision for income taxes.     We are subject to income taxes in the countries where we sell our solutions. We anticipate that in the future as we 
expand our sale of solutions to customers outside the United States, we will become subject to taxation based on the foreign statutory rates in the 
countries where these sales took place and our effective tax rate could fluctuate accordingly. Currently, each of our international subsidiaries is 
operating under cost plus agreements where the U.S. parent company reimburses the international subsidiary for its costs plus an arm's length profit. 

Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the 
difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the 
differences are expected to affect taxable income. Valuation allowances have been established to reduce deferred tax assets to the amount 
reasonably expected to be realized. Changes in valuation allowances are reflected as component of provision for income taxes.  

At December 31, 2013 , we held a $21.0 million valuation allowance against our deferred tax assets. We review on a quarterly basis our conclusions 
about the appropriate amount of its deferred income tax asset valuation allowance.

Product revenue decreased $2.6 million, or 4.1% in 2013. Device revenue decreased $1.1 million, or 2.3%, and software revenue decreased $1.5 
million, or 8.9%. The 2013 decrease in device revenue, which related entirely to our Vocera Communication solution, was due primarily to a 
decrease in the average selling price for badges and, to a lesser extent, a slight decrease in the number of badges sold. The lower average selling 
price was primarily a result of a promotion in the second quarter of 2013. The list prices for our products did not change substantially in 2013. The 
2013 decrease in software revenue was primarily due to a decrease in the number of server license seats sold for customer expansions for our Voice 
Communication solution. We believe this decrease is due to the impact on hospital operating budgets from the federal budget sequestration in 
March 2013 and uncertainty around the impact of healthcare reform within the US healthcare market, resulting in greater scrutiny of expenses and 
elongation of the sales cycle.  

Service revenue increased $4.2 million, or 11.6% in 2013. Software maintenance and support revenue increased $5.3 million, or 20.3%, and 
professional services and training revenue decreased $1.1 million, or 11.8%. The 2013 increase in software maintenance and support revenue was 
primarily a result of a larger customer base but also included $2.1 million from extended warranty contracts. The 2013 decrease in professional 
services and training revenue was due to a reduction in the number of deployments completed in 2013, particularly related to our existing customer 
base.

Cost of product revenue increased $0.2 million, or 0.8%, from 2012 to 2013. This increase was primarily due to a $1.4 million increase in warranty 
expenses and a $0.7 million increase in overhead expenses, offset by decreases in product costs of $2.3 million due to lower per unit material and 
manufacturing costs as a result of increased unit volume. The increase in warranty expenses was primarily based on a manufacturing defect 
impacting a discrete batch of badges, resulting in an increase in warranty expense of $0.7 million.  

Cost of service revenue increased $1.5 million, or 10.1%, from 2012 to 2013. This increase was primarily due to a $1.2 million increase in 
employee wages and other personnel costs in our technical support and professional services organizations to support growth in customer 
deployments and in our installed base.

Research and development expense .    Research and development expense increased $3.3 million, or 28.4%, from 2012 to 2013. This increase was 
primarily due to an increase in employee wages and other personnel related costs of $2.3 million, a $0.4 million increase in stock compensation 
expenses and $0.4 million increase in other support costs. Headcount in our research and development organization increased from 59 employees at 
December 31, 2012 to 71 employees at December 31, 2013.  

Sales and marketing expense.     Sales and marketing expense increased $11.5 million, or 34.4%, from 2012 to 2013. This increase was primarily

Interest income.     Interest income increased $0.1 million from 2012 to 2013 due to higher cash balances from the proceeds of our initial public 
offering and follow-on offering completed in 2012.  

Interest expense.     Interest expense decreased $0.1 million from 2012 to 2013 as we paid all outstanding debt upon completion of our initial public 
offering.  

Other income (expense), net.     Other expense decreased $1.4 million from 2012 to 2013 as 2012 included $1.6 million of expense related to the 
fair market value of convertible preferred stock warrants. This decrease was offset by a $0.1 million increase in interest expense related to our lease 
financing program and a $0.1 million increase in foreign exchange losses.  

Provision for income taxes.  
The $0.1 million provision on $10.4 million of pretax loss in 2013 represented a negative effective tax rate of 1.1%. For 2012, the provision of $0.6 
million on the consolidated pretax income of $3.5 million represented an effective tax rate of 17.8%. The negative effective tax rate for 2013 was 
due primarily to the impact of pre-tax losses in the U.S. operations, offset by income taxes from foreign operations. The effective tax rate of 17.8% 
for 2012 is due primarily to the impact of the utilization of the valuation allowance on net deferred tax assets, together with permanent tax 
adjustments for stock options.

Total revenue increased $21.5 million, or 27.0%, from 2011 to 2012.  

Product revenue increased $14.7 million, or 29.2% in 2012. Device revenue increased $10.6 million, or 28.7%, and software revenue increased $4.1 
million, or 30.7%. The 2012 increase in device revenue, which related entirely to our Vocera Communication solution, was driven by an increase in 
unit sales of badges and related accessories from new customers making initial purchases, existing customers expanding deployments within their 
facilities to new departments and users, and customers replacing badges. The list prices for our products did not change substantially in 2012. The 
2012 increase in software revenue was comprised of $3.5 million from an increase in the sale of licenses of our Vocera Communication solution to 
new and existing customers and $0.6 million from other software revenue.  

Service revenue increased $6.7 million, or 23.1% in 2012. Software maintenance and support revenue increased $4.8 million, or 22.4%, and 
professional services and training revenue increased $2.0 million, or 25.2%. The 2012 increase in software maintenance and support revenue was 
primarily a result of a larger customer base but also included $1.0 million from extended warranty contracts and $0.3 million from other software 
services. The 2012 increase in professional services and training revenue included $0.9 million as a result of an increase in the number of new 
deployments and expansions of our Vocera Communication solution. The remaining increase in professional services and training revenue of $0.9 
million was from other service offerings.

Cost of product revenue increased $4.1 million, or 23.4%, from 2011 to 2012. This increase was primarily due to the higher product revenue, offset 
by decreases due to lower per unit material and manufacturing costs as a result of increased unit volume and lower warranty expenses in 2012 due 
to lower return rates on our B3000 badge compared to the B2000 badge and to lower cost estimates for refurbishment and replacement alternatives. 
In 2011, we recorded a $0.6 million provision for excess inventory of the Vocera Wi-Fi smartphone due to quantities-on-hand exceeding forecast 
demand. Excluding the excess inventory charge, product gross margins in 2011 would have been only 0.4% lower than those realized in 2012.  

Cost of service revenue increased $1.0 million, or 7.3%, from 2011 to 2012. This increase was primarily due to a $0.9 million increase in employee 
wages and other personnel costs in our technical support and professional services organizations to support growth in customer deployments and in 
our installed base. Headcount in our services organization increased from 71 employees at December 31, 2011 to 80 employees at December 31, 
2012.

Sales and marketing expense.     Sales and marketing expense increased $5.3 million, or 18.8%, from 2011 to 2012. This increase was primarily due 
to a $4.1 million increase in employee wages and other personnel costs to support corporate marketing and sales efforts, a $1.0 million increase in 
stock compensation expenses, $0.4 million increase in travel, $0.5 million increase in other support, offset by a $0.7 million decrease in brand and 
product launch expenses associated with the B3000 release in 2011. Headcount in our sales and marketing organization increased from 115

Provision for income taxes. The $0.6 million provision on $3.5 million of pretax income in 2012 represented an effective tax rate of 17.8%. For 
2011, the provision of $0.3 million on the consolidated pretax loss of $2.2 million represented a negative effective rate of 13.0%. The lower-than-
normal 17.8% rate for 2012 was due primarily to the impact of the utilization of the valuation allowance on net deferred tax assets, together with 
permanent tax adjustments for stock options. The negative 13.0% rate for 2011 is due primarily to the increase in the valuation allowance on net 
deferred tax assets, together with tax liabilities in the foreign subsidiaries.

On April 2, 2012, we completed our initial public offering in which we and existing stockholders sold 6,727,500 shares of common stock at $16.00 
per share, before underwriting discounts and commissions. We sold 5,000,000 shares and existing stockholders sold an aggregate of 1,727,500 
shares, including 877,500 shares as a result of the underwriters’ exercise of their over-allotment option. We recorded net proceeds of $70.5 million 
from the initial public offering, after subtraction of underwriters’ discounts and commissions, and offering expenses incurred in both 2011 and 
2012. We did not receive any proceeds from the sale of shares by existing stockholders in our initial public offering.  

On September 12, 2012, we completed a follow-on public offering in which we and existing stockholders sold 5,548,750 shares of common stock at 
$28.75 per share, before underwriting discounts and commissions. We sold 1,337,500 shares and existing stockholders sold an aggregate of 
4,211,250 shares, including an aggregate of 723,750 shares as a result of the underwriters' exercise of their over-allotment option. We received net 
proceeds of approximately $36.0 million, after deducting underwriting discounts and commissions and other expenses of the offering. We did not 
receive any proceeds from the sale of shares by existing stockholders in our follow-on public offering.  

We have also financed a portion of our operations and acquisitions with term loans, equipment lines of credit and revolving lines of credit. In 
January 2009, we entered into a loan and security agreement with Comerica Bank, N.A., or Comerica, which was subsequently amended in 
February 2010 and December 2010. These amendments renewed the working capital line of credit for $5.0 million, and increased the term loan 
facility from $2.0 million to $5.0 million. In April 2012, we used a portion of the proceeds from our initial public offering to pay in full the 
outstanding revolving line of credit of $4.5 million and the outstanding term loan balance of $3.3 million. We allowed this line of credit to expire in 
April 2012.  

Proceeds from transfers of our 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 components are accounted for as financing liabilities.  

We are not a capital-intensive business, nor do we expect to be in the future. During 2013 , 2012 and 2011 , our purchases of property and 
equipment were $3.8 million, $2.6 million and $2.4 million, respectively. The expenditures in 2013 included completion of the first phase of our 
ERP implementation in August 2013 and build out of additional leased space available in April 2013. The expenditures in 2012 included progress 
to date on our ERP implementation, as well as spending to support headcount growth with computer and equipment needs. The expenditures in 
2011 primarily related to leasehold improvements and computer equipment to support the increase in our headcount and B3000 production 
equipment.  

We believe that our existing sources of liquidity will satisfy our anticipated working capital and capital requirements for at least the next 
twelve months. Our future liquidity and capital requirements will depend upon numerous factors, including our rate of growth, the rate at which we 
add personnel to generate and support future growth, and potential future acquisitions.  

In the future, we may seek to sell additional equity securities or borrow funds. The sale of additional equity or convertible securities may result in 
additional dilution to our stockholders. If we raise additional funds through the issuance of debt securities or other borrowings, these securities or 
borrowings could have rights senior to those of our common stock and could contain covenants that could restrict our operations. Any required 
additional capital may not be available on reasonable terms, if at all.  

Operating activities  

Cash used by operating activities was $1.3 million in 2013, due in part to the 2013 net loss of $10.5 million , together with inventory growth of $3.0 
million attributable to downward revision of projections for our 2013 shipments which did not significantly reduce the lagged inventory receipt 
commitments until year-end , accounts receivable growth of $1.9 million , and decrease in accrued and other liabilities of $1.9 million . These were 
partially offset by non-cash items, including stock-based compensation of $8.7 million , higher than in 2012, and depreciation of property and 
equipment and intangibles amortization of $2.5 million . Additional offset was provided by the increase in deferred revenues of $4.2 million and the 
increase of $0.7 million in accounts payable.  

Cash provided by operating activities was $12.3 million in 2012, due in part to net income in 2012 of $2.9 million, based on 3.3% higher gross 
margins on a 27% increase in revenues. Operating cash flow also excludes the following non-cash items: depreciation of property and equipment 
and intangibles amortization of $2.6 million, the mark-to-market valuation of preferred stock warrants of $1.6 million prior to our initial public 
offering, and stock-based compensation of $4.2 million, which was higher in 2012 than in 2011 due to the higher quantity and fair value of stock 
option and RSU grants. Additional operating cash inflows were generated by the $5.8 million increase in deferred revenues and $2.8 million 
increase in accrued and other liabilities, both driven by our continued business growth. These items were partially offset by operating cash outflows 
of $5.9

Table of Contents  

million for the growth-driven increase in accounts receivable, $1.3 million for the increase in prepaid expenses and other current assets, and $1.1 
million for the decrease in accounts payable.  

Cash provided by operating activities was $5.5 million in 2011, which was primarily due to an increase in deferred revenue of $6.3 million as a 
result of the increase in sales in 2011, the change in accounts payable of $3.0 million, an increase in accrued and other liabilities of $1.4 million, 
stock-based compensation expense of $1.5 million, changes in the valuation of preferred stock warrants and option liabilities of $1.4 million, and 
depreciation of property and equipment and amortization of intangible assets of $2.0 million. This was offset by a net loss of $2.5 million and 
change in accounts receivable of $6.7 million due to the increase in volume and the timing of product shipments during 2011. Inventory increased 
$1.1 million in 2011 as we began transitioning to the B3000 badge.  

Investing activities  

Cash used in investing activities was $56.7 million in 2013, which was primarily attributable to the purchase of short-term investments of $118.7 
million , net of maturities received of $65.7 million , plus the purchase of property and equipment and leasehold improvements of $3.8 million . The 
short-term investment purchases primarily reflected our decision in early 2013 to migrate all investment and cash equivalents from our single asset 
manager into new portfolios, split between two new asset managers. The maturities reflected the proceeds from the liquidation of the former asset 
manager's portfolio, as well as fairly short-term maturities on the new portfolios, leading to a short-term investments balance of $88.0 million as of 
December 31, 2013 , with the remainder invested in cash equivalents.  

Cash used in investing activities was $37.5 million in 2012, which was primarily attributable to the purchase of short-term investments of $104.9 
million, net of maturities received of $69.9 million, plus the purchase of property and equipment and leasehold improvements of $2.6 million. The 
short-term investment purchases reflected investment for higher yields of the proceeds from the April 2012 IPO and September 2012 follow-on 
offerings. We allowed the short-term investments to liquidate down to a $35.0 million balance as of December 31, 2012 , with the difference 
invested in cash equivalents from the maturities.  

Cash used in investing activities was $2.5 million in 2011, which was primarily attributable to the purchase of property and equipment and 
leasehold improvements related to expansion of our corporate offices. Our purchases of property and equipment during the year were higher than 
normal as we expanded our leasehold improvements and procured additional computer equipment to support the increase in headcount. We also 
invested in manufacturing tools and equipment to support our newly introduced B3000 badge.  

Financing activities      

Cash provided by financing activities was $5.1 million in 2013, which was attributable to employee stock purchase plan proceeds of $3.0 million , 
exercises of stock options of $1.8 million , cash from lease-related performance obligations of $0.8 million , exercise of common stock warrants of 
$0.2 million , partially offset by $0.7 million of taxes paid on behalf of employees for net share settlement.       

Cash provided by financing activities was $102.9 million in 2012, which was primarily attributable to the net proceeds received from our initial 
public offering of $72.1 million and the net proceeds from our follow-on offering of $36.0 million, partially offset by the $8.3 million repayment of 
our credit facility and term loan. Additional financing activities that contributed cash included $1.7 million of proceeds from the exercise of stock 
options and $1.1 million of cash received for future executory costs for lease-related performance obligations.  

Cash provided by financing activities was $3.2 million in 2011, which was primarily attributable to a $2.9 million net increase in debt and 
$1.8 million in proceeds from the exercise of stock options and preferred stock warrants offset by $1.5 million of expenses related to our initial 
public offering.

(2)   Consists of minimum purchase commitments with our independent contract manufacturer and other vendors. 

As of December 31, 2013 we had $216,000 of net deferred tax liabilities and $170,000 from uncertain tax positions, both recorded within other 
long-term liabilities. The timing and amounts of any payments which could result from the net deferred tax liabilities and unrecognized tax benefits 
will depend upon a number of factors. Accordingly, the timing and amounts of any eventual payment cannot be estimated for inclusion in the table 
above. We do not expect a significant tax payment related to these obligations to occur within the next 12 months. Such tax contingencies are 
separately disclosed and discussed in Note 10.  

Related party transactions  

During the years ended December 31, 2013 and 2012 we billed a related party, the University of Chicago Medical Center (“UCMC”), $0.5 million 
in each year for consulting services and technology solutions. One of our board members, Sharon O’Keefe, is also the President of UCMC. These 
transactions were recorded at arms-length prices. There were no material related party transactions for UCMC in the year ended December 31, 
2011 . During the year ended December 31, 2013 , we billed a related party, the Hewlett-Packard Company, approximately $9,200 for software and 
support, at arms’ length prices. Through July of 2013, John N. McMullen, one of our directors, served as Treasurer & Senior Vice President at 
Hewlett-Packard. There were no  material related party transactions for Hewlett-Packard in the years ended December 31, 2012 and  2011.  

Off-balance sheet arrangements  

During 2013 , we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special 
purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or 
limited purposes.  

Critical accounting policies and estimates  

The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the 
consolidated financial statements and accompanying notes. We evaluate our estimates on an ongoing basis, including those related to revenue 
recognition, stock-based compensation, accounting for business combinations and the provision for income taxes. We base our estimates and 
judgments on our historical experience, knowledge of factors affecting our business and our belief as to what could occur in the future considering 
available information and assumptions that we believe to be reasonable under the circumstances.  

The accounting estimates we use in the preparation of our consolidated financial statements will change as events occur, more experience is 
acquired, additional information is obtained and our operating environment changes. Changes in estimates are made when circumstances warrant. 
Such changes in estimates and refinements in estimation methodologies are reflected in our reported results of operations and, if material, the 
effects of changes in estimates are disclosed in the notes to our consolidated financial statements. By their nature, these estimates and judgments are 
subject to an inherent degree of uncertainty and actual results could differ materially from the amounts reported based on these estimates.  

While our significant accounting policies are more fully described in Note 1 of the “Notes to our consolidated financial statements” included in 
Item 8, “Financial Statements and Supplementary Data,” we believe the following reflects our critical accounting policies and our more significant 
judgments and estimates used in the preparation of our financial statements.  

Revenue recognition  

42  

 
   
 
 
 
 
 
 
 
  
  
  
  
  
  
Table of Contents  

We derive revenue from the sales of communication badges, smartphones, perpetual software licenses for software that is essential to the 
functionality of the communication badges, software maintenance, extended warranty and professional services. We also derive revenue from the 
sale of licenses for software that is not essential to the functionality of the communication badges, as well as certain subscription-based revenues. 
Sales tax is excluded from reported total revenue.  

Revenue is recognized when all of the below criteria are met:  

•  

there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from 
a third party;  

•   delivery has occurred or services have been rendered; 

•  

•  

the price is fixed or determinable after evaluating the risk of concession; and 

collectability is reasonably assured based on customer creditworthiness and past history of collection. 

A typical sales arrangement involves multiple elements, such as sales of communications badges, perpetual software licenses, professional services 
and maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale 
of communication badges and perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual 
provisions governing sales of these products do not include any provisions regarding acceptance, performance or general right of return or 
cancellation or termination provisions adversely affecting revenue recognition. Revenue from the sale of maintenance services on software licenses 
is recognized over the period during which the services are provided, which is generally one year. Revenue from professional services is recognized 
either on a fixed fee basis based on milestones or on a time and materials basis as the services are provided, both of which generally take place over 
a period of two to twelve weeks.  

For contracts that were signed prior to January 1, 2010 and were not materially modified after that date, we recognize revenue on such 
arrangements in accordance with the discussion under the authoritative guidance for software revenue recognition.  

For revenue arrangements entered into or materially modified after January 1, 2010, we have adopted the amended October 2009 guidance from 
Financial Accounting Standards Board (“FASB”) for revenue recognition for tangible products containing software components that function 
together to deliver the products essential functionality. The new guidance also amended the multiple element arrangement accounting.  

Under the new guidance, tangible products and the essential software licenses that work together with such tangible products to provide them their 
essential functionality are now not subject to software revenue recognition accounting rules (non-software elements), while non-essential software 
licenses are still governed under software revenue recognition rules (software elements).  

The adoption of the amended revenue recognition guidance did not result in any significant changes to the individual deliverables to which we 
allocate revenue as the fair value for most of the deliverables is based on VSOE, or to the timing of revenue recognized from the individual 
deliverables.  

We also derive revenue from the provision of hosted services on a subscription basis and software sold under term licenses. Revenue from the sale 
of these products and services are not sold as part of multiple element arrangements and such arrangements are recognized ratably over the term of 
the arrangement.  

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 such as extended warranty and battery refresh programs 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 initially as financing liabilities, with subsequent amortization recorded in revenue, for extended 
warranty and battery refresh programs, offset by interest expense.  

Standard product warranties  

We provide for the estimated costs of product warranties at the time the related revenue is recognized. Costs are estimated based on historical and 
projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific product 
warranty includes parts and labor over a period generally ranging from one to three years.  

43  

 
 
 
 
Table of Contents  

We provide no warranty for software. We regularly assess our estimates to evaluate the adequacy of the recorded warranty liabilities and adjust the 
amounts as necessary. The total warranty expense in 2013 was $1.7 million, compared to $0.3 million in 2012. The increase in warranty expense 
was due to a manufacturing defect relating to a discrete batch of badges, aggregating  $0.7 million. One of the key drivers to the warranty reserve 
calculation is the estimated return rate of the installed base of products under standard warranty. We estimate that a 1 percentage change in the 
product return rate would impact the warranty expenses by $85,000 per year.  

Stock-based compensation  

Stock options  

We record all stock-based awards, which consist of stock option grants, at fair value as of the grant date and recognize the expense over the 
requisite service period (generally over the vesting period of the award). The expenses relating to these awards have been reflected in our financial 
statements. Stock options granted to our employees vest over periods of 12 to 48 months.  

We use the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the following 
major inputs: the estimated fair value of the underlying common stock, the expected life of the option, the expected volatility of the underlying 
common stock over the expected life of the option, the risk-free interest rate and expected dividend yield. The following assumptions were used for 
each respective period for employee stock-based compensation:  

Expected term (in years)  
Volatility  
Risk-free interest rate  
Dividend yield  

2013  
5.38 - 5.43  
46.7% - 48.1%  
0.81% - 1.80%  
0.0%  

Years ended December 31,  
2012  
5.23 - 5.60  
47.9% - 48.7%  
0.72% - 1.03%  
0.0%  

2011  
5.49 - 5.73  
44.7% - 47.6%  
0.98% - 2.48%  
0.0%  

The Company bases the risk-free rate for the expected term of options on the U.S. Treasury Constant Maturity Rate as of the grant date. The 
computation of expected life was determined based on the historical exercise and forfeiture behavior of our employees, giving consideration to the 
contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The expected stock price volatility for 
our common stock was estimated based on the historical volatility of a group of comparable companies for the same expected term of our options. 
The comparable companies were selected based on industry and market capitalization data. We assumed the dividend yield to be zero, as we have 
never declared or paid dividends and do not expect to do so in the foreseeable future.  

Stock-based compensation expense is recognized based on a straight-line amortization method over the respective vesting period of the award and 
has been reduced for estimated forfeitures. We estimated the expected forfeiture rate based on our historical experience, considering voluntary 
termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent our actual forfeiture rate 
is different from our estimate, the stock-based compensation expense is adjusted accordingly.  

Restricted Stock Units  

During the year ended December 31, 2012, we began incorporating restricted stock units as an element of our compensation plans. Beginning in 
May 2012, we granted certain employees restricted stock units, which vest one third on the first anniversary of the grant, one third on the second 
anniversary of the grant and one third upon the third anniversary of the grant. We did not grant any restricted stock units prior to May 2012. The 
grant date fair value of the RSUs is the closing market price on the date of grant; this amount is charged to expense ratably over the requisite service 
period. Beginning with 2012, RSU's have formed the largest form of stock compensation expense, in terms of grant type.  

Goodwill and intangible assets  

We allocate the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase 
price is recorded as goodwill. The allocation of the purchase price requires management to make significant estimates in determining the fair values 
of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on information obtained from 
management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that an asset is 
expected to generate in the future, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and 
unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the acquired  

44  

 
 
     
  
     
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
Table of Contents  

assets and liabilities differently from the allocation that we have made. In addition, unanticipated events and circumstances may occur which affect 
the accuracy or validity of such estimates, and if such events occur we may be required to record a charge against the value ascribed to an acquired 
asset or an increase in the amounts recorded for assumed liabilities.  

Goodwill  

Goodwill is tested for impairment at the reporting unit level at least annually as of September 30th, or more often if events or changes in 
circumstances indicate the carrying value may not be recoverable. No impairment was recorded in 2013 , 2012 or 2011 . As of December 31, 2013 , 
no changes in circumstances indicate that goodwill carrying values may not be recoverable. Application of the goodwill impairment test requires 
judgment. Circumstances that could affect the valuation of goodwill include, among other things, a significant change in our business climate and 
the buying habits of our customers along with changes in the costs to provide our products and services. For the September 30, 2013 goodwill 
impairment test, we used the qualitative assessment permitted under recent accounting guidance, and concluded there was no goodwill impairment, 
without proceeding to Steps 1 and 2 of the quantitative approach.  

Intangible assets  

In connection with the acquisitions we made in 2010, we recorded intangible assets. We applied an income approach to determine the values of 
these intangible assets. The income approach measures the value of an asset based on the future cash flows it is expected to generate over its 
remaining life. The application of the income approach requires estimates of future cash flows based upon, among other things, certain assumptions 
about expected future operating performance and an appropriate discount rate determined by our management. In applying the income approach, we 
used the excess earnings method to value our customer relationships and in-process research and development intangible assets and the relief from 
royalty method to value our developed technology and trade name intangible assets. We used the with-and-without method to value a non-compete 
intangible asset. The cash flows expected to be generated by each intangible asset were discounted to their present value equivalent using rates 
believed to be indicative of market participant discount rates. Intangible assets are amortized over their estimated useful lives. Upon completion of 
development, acquired in process research and development assets are generally considered amortizable, finite-lived assets and are amortized over 
their estimated useful lives.  

Finite-lived intangible assets consist of customer relationships, developed technology, trademarks and non-compete agreements. We evaluate our 
intangible assets for impairment at the asset group level, which means the intangibles grouped with other assets and liabilities at the lowest level for 
which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Management has concluded that the 
Company's asset groups align with the Company's reporting units. The intangibles assets are allocated to the Product asset group, given that the 
Product asset group is the lowest level for which discrete cash flow information are identifiable, independent from other assets. We assess the 
recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future 
cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the 
period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was 
recorded in 2013 , 2012 or 2011 .  

Significant judgments required in assessing the impairment of goodwill and intangible assets include the identification of reporting units, 
identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate 
discount and growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value 
as to whether an impairment exists and, if so, the amount of that impairment.  

Income taxes      

We use the asset and liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary 
differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect 
when we recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax 
carryforwards or the projected operating results indicate that realization is not likely, we provide for a valuation allowance. Valuation allowances 
are established when necessary to reduce deferred tax assets to the amounts expected to be realized.  

We have deferred tax assets, resulting from deductible temporary differences that may reduce taxable income in future periods. A valuation 
allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a 
valuation allowance, we estimate future taxable income, considering the feasibility of ongoing tax-planning strategies and the realizability of tax 
loss carryforwards. Valuation allowances related to deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates and 
future taxable income levels. If we were to determine that we would be able to realize our deferred tax assets in the future in excess of the net 
carrying amounts, we would decrease the recorded valuation allowance through an increase to income in the period in which that determination is 
made. Due to the  

45  

 
 
Table of Contents  

amount of net operating losses available for income tax purposes through December 31, 2013 , we had a full valuation reserve against our deferred 
tax assets. We continue to evaluate the realizability of our U.S. and Canadian deferred tax assets. If our financial results improve, we will reassess 
the need for a full valuation allowance each quarter and, if we determine that it is more likely than not the deferred tax assets will be realized, we 
will adjust the valuation allowance.  

At December 31, 2013 , we had a valuation allowance against net deferred tax assets of $21.0 million . We intend to review on a quarterly basis our 
conclusions about the appropriate amount of its deferred income tax asset valuation allowance. In the ordinary course of business, there is inherent 
uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination 
based upon our management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it 
is more likely than not that a tax benefit will be sustained, we have recorded the highest amount of tax benefit with a greater than 50% likelihood of 
being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions 
where it is not more likely than not that a tax benefit will be realizable, no tax benefit has been recognized in our financial statements.  

We include interest and penalties with income taxes on the accompanying statement of operations. Our tax years after 2009 are subject to tax 
authority examinations. Additionally, our net operating losses and research credits prior to 2013 are subject to tax authority adjustment.  

Recently issued accounting guidance  

In July 2013, the 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 is effective for our first quarter of 2014, applied prospectively. We 
have the option to apply the rule retrospectively and early adoption is permitted. Adoption of this standard is not expected to impact our financial 
position or results of operations.  

Item 7A.   Quantitative and Qualitative Disclosures about Market Risk 

The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. To achieve 
this objective, historically we have invested in money market funds. With the proceeds from our two public offerings in 2012, we have invested in a 
broader portfolio of high credit quality short-term securities. To minimize the exposure due to an adverse shift in interest rates, we maintain an 
average portfolio duration of one year or less.  

Our primary exposure to market risk is interest income and expense sensitivity, which is affected by changes in the general level of the interest rates 
in the United States. However, because of the short-term nature of our interest-bearing securities, a 10% change in market interest rates would not 
be expected to have a material impact on our consolidated financial condition or results of operations.  

Historically our operations have consisted of research and development and sales activities in the United States. As a result, our financial results 
have not been materially affected by factors such as changes in foreign currency exchange rates or economic conditions in foreign markets. We are 
developing plans to expand our international presence. Accordingly, we expect that our exposure to changes in foreign currency exchange rates and 
economic conditions may increase in future periods.

Report of Independent Registered Public Accounting Firm  

To The Board of Directors and Stockholders  
of Vocera Communications, Inc.:  

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of stockholders' equity 
(deficit), comprehensive income (loss) and cash flows present fairly, in all material respects, the financial position of Vocera Communications, Inc. 
and its subsidiaries at December 31, 2013 and December 31, 2012, and the results of their operations and their cash flows for each of the three years 
in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. These 
financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements 
and financial statement schedules based on our audits. We conducted our audits of these statements in accordance with the standards of the Public 
Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the 
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and 
evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

1.   The Company and Summary of Significant Accounting Policies 

Notes to Consolidated Financial Statements  

Background  

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 U.S. and internationally. Today the 
majority of the Company's business is from healthcare, but the Company is expanding its sales and marketing efforts to enter and grow 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 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 Hand-Off, Inc., Vocera Canada, Ltd. and ExperiaHealth, Inc. in 2010 and 
Vocera Communications India Private Ltd. in 2013. In August 2013, we merged Vocera Hand-Off Communications, Inc. and ExperiaHealth, Inc. 
into our parent company, Vocera Communications, Inc.  

Since its inception, the Company has incurred significant losses and, as of December 31, 2013 , had an accumulated deficit of $64.4 million . The 
Company has funded its operations primarily with customer payments for its products and services, proceeds from the issuance of common stock in 
connection with its IPO and follow-on offering and, before the IPO, from the issuances of convertible preferred stock and from borrowings under its 
term loan facility and the utilization of its line of credit. As of December 31, 2013 , the Company had cash, cash equivalents and short-term 
investments of $127.7 million , primarily as a result of its two public offerings in 2012 and subsequent net cash flows.  

The Company believes that its existing sources of liquidity will satisfy its working capital and capital requirements for at least the next twelve 
months. Failure to generate sufficient revenue, achieve planned gross margins, or control operating costs may require the Company to raise 
additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all, and could require 
the Company to modify, delay or abandon some of its planned future expansion or expenditures or reduce some of its ongoing operating costs, 
which could harm its business, operating results, financial condition and ability to achieve its intended business objectives. If the Company raises 
additional funds through  
further issuances of equity, convertible debt securities or other securities convertible into equity, its existing stockholders could suffer significant 
dilution in their percentage ownership of the Company and any new securities it issues could have rights, preferences and privileges senior to those 
of holders of its common stock.  

Basis of presentation  

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company 
transactions and balances have been eliminated in consolidation. The accompanying notes are prepared in accordance with accounting principles 
generally accepted in the United States (“GAAP”).  

The board of directors of the Company and its stockholders approved a 1-for-6 reverse stock split of the Company’s common and preferred shares 
that was effected on March 26, 2012. All share and per share information included in the accompanying consolidated financial statements have 
been adjusted to reflect this reverse stock split.  

Use of estimates  

The preparation of financial statements in conformity with 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, warranty reserves, inventory 
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.  

Cash, cash equivalents and short-term investments  

The Company’s cash equivalents and short-term investments consist of money market funds, commercial paper, U.S. government agency notes, 
U.S. Treasury notes, municipal debt and corporate debt. These investments are classified as  

54  

 
 
Table of Contents  

available-for-sale securities and are carried at fair value with the unrealized gains and losses reported as a component of stockholders’ equity. 
Management determines the appropriate classification of its investments at the time of purchase and re-evaluates the available-for-sale designations 
as of each balance sheet date. Investments with an original purchase maturity of less than three months are classified as cash equivalents, all those 
with longer maturities are classified as short-term investments, which are available-for-sale.  

Restricted cash  

Restricted cash was $0.3 million at December 31, 2013 and 2012 , respectively, the majority of which is security for a corporate travel card facility 
and credit card processing services. All restricted cash is classified as curr ent, under prepaids and other current assets on the consolidated balance 
sheet, based on the underlying terms of the arrangem ents.  

Allowance for doubtful accounts  

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio 
determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The 
Company has not experienced significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ 
payment histories and associated credit risks as it does not require collateral from its customers.  

The following table presents the changes in the allowance for doubtful accounts:

Inventories are valued at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value or 
replacement cost). The Company assesses the valuation of inventory and periodically writes down the value for estimated excess and obsolete 
inventory based upon assumptions about future demand and market conditions.  

Concentration of credit risk and other risks and uncertainties  

Financial instruments that subject the Company to concentration of credit risk consist primarily of cash, cash equivalents and short-term 
investments. The Company’s cash and cash equivalents are primarily deposited with high quality financial institutions and in money market funds. 
Deposits at these institutions and funds may, at times, exceed federally insured limits. Management believes that these financial institutions and 
funds are financially sound and, accordingly, that minimal credit risk exists. The Company has not experienced any losses on its deposits of cash 
and cash equivalents. Marketable securities are stated at fair value, and accounted for as available-for-sale within short-term investments. The 
counterparties to the agreements relating to the Company’s investment securities consist of major corporations, financial institutions and 
government agencies of high credit standing.  

The primary hardware component of the Company’s products is currently manufactured by a third-party contractor in Mexico. A significant 
disruption in the operations of this contractor may impact the production of the Company’s products for a substantial period of time, which could 
harm the Company’s business, financial condition and results of operations.  

Concentration of credit risk with respect to trade accounts receivable is considered to be limited due to the diversity of the Company’s customer 
base and geographic sales areas. At December 31, 2013 and 2012 , no customer accounted for 10% or more of accounts receivable. For the years 
ended December 31, 2013 , 2012 and 2011 , no customer represented 10% or more of revenue.  

Property and equipment  

Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful economic lives of the assets. Assets 
generally have useful economic lives of three years except for leasehold improvements, which are amortized  

55  

 
   
 
     
  
  
  
  
  
  
  
  
Table of Contents  

using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related assets. Purchased or developed 
software also generally has a three year useful economic life, except for major ERP implementations, for which the Company assumes a five year 
useful economic life. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the consolidated 
balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs which are not considered improvements and do not 
extend the useful life of the assets are charged to operations as incurred.  

The Company periodically reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying 
amount of an asset is impaired or the estimated useful lives are no longer appropriate. Fair value is estimated based on discounted future cash flows. 
If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the 
asset, an impairment loss is recorded to write the asset down to its estimated fair values. To date, the Company has not recorded any impairment 
charges.  

Software development costs.   

For internal-use software, the Company capitalizes certain internal and external costs incurred in its acquisition and creation. Capitalized internal-
use software is included in property and equipment when development is complete and is amortized on a straight-line basis over the estimated 
useful life of the related asset , generally three years, except that five years is assumed for major ERP implementations. Per the authoritative 
guidance, costs incurred either before or after the period satisfying the capitalization criteria, together with costs incurred for training and 
maintenance, are expensed as incurred. For the years ended December 31, 2013 , 2012 and 2011 , the Company capitalized costs of $2.1 million , 
$1.1 million and $0.3 million , respectively.  

Goodwill and intangible assets  

The Company allocates the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any 
residual purchase price is recorded as goodwill. The allocation of the purchase price requires management to make significant estimates in 
determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. These estimates are based on 
information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the 
cash flows that an asset is expected to generate in the future, and the cost savings expected to be derived from acquiring an asset. These estimates 
are inherently uncertain and unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the 
acquired assets and liabilities differently from the allocation that the Company has made. In addition, unanticipated events and circumstances may 
occur which may affect the accuracy or validity of such estimates. If such events occur we may be required to record a charge against the value 
ascribed to an acquired asset or an increase in the amounts recorded for assumed liabilities.  

Goodwill  

Goodwill is tested for impairment at the reporting unit level at least annually or more often if events or changes in circumstances indicate the 
carrying value may not be recoverable. As of December 31, 2013 , no changes in circumstances indicate that goodwill carrying values may not be 
recoverable. Application of the goodwill impairment test requires judgment. Circumstances that could affect the valuation of goodwill include, 
among other things, a significant change in the Company's business climate and the buying habits of the Company's customers along with changes 
in the costs to provide the Company's products and services. The Company has identified two operating segments (Product and Service) which 
management also considers to be reporting units. For the 2013 goodwill impairment test, the Company used the qualitative assessment permitted 
under recent accounting guidance, and concluded there was no goodwill impairment, without proceeding to Steps 1 and 2 of the quantitative 
approach.  

Intangible assets  

Intangible assets are amortized over their estimated useful lives. Upon completion of development, acquired in-process research and development 
assets are generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives. Finite-lived intangible assets 
consist of customer relationships, developed technology, trademarks and non-compete agreements. The Company evaluates intangible assets for 
impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that 
expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An 
impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No 
impairment of intangible assets was recorded in 2013 , 2012 or 2011 .  

Significant judgments required in assessing the impairment of goodwill and intangible assets include the identification of reporting units, 
identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate 
discount and revenue growth rates and other assumptions. Changes in these estimates and  

56  

 
 
Table of Contents  

assumptions could materially affect the determination of fair value as to whether an impairment exists and, if so, the amount of that impairment.  

Convertible preferred stock  

Prior to the Company’s IPO, the Company had issued and outstanding six series of convertible preferred stock. As of December, 31, 2011, the 
proceeds recorded were $53.0 million with liquidation preference of $53.6 million . Each share of preferred stock was convertible, at the option of 
the holder, into common stock. Series A, Series C, Series D, Series E and Series F had a conversion ratio of 1:1. Series B preferred stock had a 
conversion ratio of 1:1.8304. In connection with the Company’s IPO, in April 2012, each share of then-outstanding preferred stock automatically 
converted into common stock at the ratio described above. In the statement of shareholders' equity for the year ended December 31, 2012 , this was 
recorded as non-cash conversion of $53.4 million from preferred stock to common stock.  

Deferred Costs of Revenue  

When the Company’s products have been delivered, but the product revenue associated with the arrangement has been deferred as a result of not 
meeting the revenue recognition criteria, the Company also defers the related inventory costs for the delivered items. As of December 31, 2013 and 
2012 , respectively, the Company included $144,000 and $4,000 of such deferred cost of revenue as part of “Prepaid expenses and other current 
assets” in the accompanying consolidated balance sheet.  

Revenue recognition  

The Company derives revenue from the sales of communication badges, smartphones, perpetual software licenses for software that is essential to 
the functionality of the communication badges, software maintenance, extended product warranty and professional services. The Company also 
derives revenue from the sale of licenses for software that is not essential to the functionality of the communication badges. Sales tax is excluded 
from reported total revenue.  

Revenue is recognized when all of the below criteria are met:  

•  

there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from 
a third party;  

•   delivery has occurred or services have been rendered; 

•  

•  

the price is fixed or determinable after evaluating the risk of concession; and 

collectability is reasonably assured based on customer creditworthiness and past history of collection. 

A typical sales arrangement involves multiple elements, such as sales of communication badges, perpetual software licenses, professional services 
and maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale 
of communication badges and perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual 
provisions governing sales of these products do not include any provisions regarding acceptance, performance or general right of return or 
cancellation or termination provisions adversely affecting revenue recognition. Revenue from the sale of maintenance services on software licenses 
is recognized over the period during which the services are provided, which is generally one year. Revenue from professional services is recognized 
either on a fixed fee basis based on milestones or on a time and materials basis as the services are provided, both of which generally take place over 
a period of two to twelve weeks.    

The Company also derives revenue from the provision of hosted services on a subscription basis and software sold under term licenses. Revenue 
from the sale of these products and services are not sold as part of multiple element arrangements and such arrangements are recognized ratably 
over the term of the arrangement.  

Revenue from sales-type leases  

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.  

57  

 
   
 
 
Table of Contents  

For the year ended December 31, 2013 , the Company transferred $2.2 million  of lease receivables, recording an immaterial net gain and  $0.8 
million  of new financing liabilities for future performance of executory service obligations. For the year ended December 31, 2012 , the Company 
transferred $3.8 million of lease receivables, recording an immaterial net gain and  $1.1 million  of new financing liabilities for future performance 
of executory service obligations.  

For lease receivables retained as of December 31, 2013 and 2012 , respectively, the Company recorded  $1.4 million and $0.5 million of net 
investment in sales-type leases, equivalent to the minimum lease payments for the delivered product.  

Commissions expense  

Sales commissions are recorded as sales and marketing expense and accrued current liability as orders are recorded; thus no contract acquisition 
costs are capitalized.  

Shipping and handling costs  

Shipping and handling costs charged to customers are included in revenue and the associated expense is recorded in cost of products sold in the 
statements of operations for all periods presented.  

Research and development expenditures  

Research and development costs are charged to operations as incurred. Software development costs incurred prior to the establishment of 
technological feasibility are included in research and development and are expensed as incurred. After technological feasibility is established, 
material software development costs up to general availability of the software will be capitalized and amortized on a straight-line basis over the 
estimated product life, or based on the ratio of current revenues to total projected product revenues, whichever is greater. To date, the time between 
the establishment of technological feasibility and general availability has been very short and therefore no significant costs have been incurred. 
Accordingly, the Company has not capitalized any software development costs.  

Advertising costs  

Advertising costs are included in sales and marketing expense and are expensed as incurred. Advertising costs for the years ended December 31, 
2013 , 2012 and 2011 were immaterial.  

Product warranties  

The Company offers warranties on certain products and records a liability for the estimated future costs associated with warranty claims, which is 
based upon historical experience and the Company’s estimate of the level of future costs. The Company provides for the estimated costs of 
hardware warranties at the time the related revenue is recognized. Costs are estimated based on historical and projected product failure rates, 
historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty includes parts and labor 
over a period generally ranging from one to three years. The Company provides no warranty for software. The Company regularly re-evaluates its 
estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary. Warranty costs are reflected in the 
consolidated statement of operations as cost of sales.  

Stock-based compensation  

For options granted to employees, stock-based compensation is measured at grant date based on the fair value of the award and is expensed on a 
straight-line basis over the requisite service period. The Company determines the grant date fair value of the options using the Black-Scholes 
option-pricing model. Restricted stock awards and restricted stock units, first awarded in 2012, result in compensation expense, straightlined over 
the requisite service period, based on the award date closing stock price. Equity instruments issued to non-employees are recorded at their fair value 
on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest. The fair value of options granted to non-
employees is amortized over the vesting period, on a straight-line basis.  

For stock options issued to employees and non-employees with specific performance criteria, the Company makes a determination at each balance 
sheet date whether the performance criteria are probable of being achieved. Compensation expense is recognized until such time as the performance 
criteria are met or when it is probable that the criteria will not be met.  

The Company will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is realized after 
all other tax attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the indirect 
effects of stock-based awards on other tax attributes, such as the research tax credit, through its statement of operations.

In 2012, the Company began incorporating restricted stock awards and RSUs as an element of our compensation plans. In 2012, the Company 
granted certain of its directors restricted stock which vests 50% on the first anniversary of the grant, and 50% on the second anniversary of the 
grant. In 2013, the Company began granting certain of its directors RSUs which vest 100% on the first anniversary of the grant. In 2012, the 
Company began granting certain employees RSUs, which vest one third on the first anniversary of the grant, one third on the second anniversary of 
the grant and one third upon the third anniversary of the grant.  

Income taxes  

The Company uses the asset and liability method of accounting for income taxes. Under this method, the Company records deferred income taxes 
based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that the 
Company expects will be in effect when they recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases 
where the expiration date of tax carryforwards or the projected operating results indicate that realization is not likely, the Company provides for a 
valuation allowance. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.  

The Company has deferred tax assets, resulting from net operating losses, research and development credits and temporary differences that may 
reduce taxable income in future periods. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset 
will not be realized. In assessing the need for a valuation allowance, the Company estimates future taxable income, considering the feasibility of 
ongoing tax-planning strategies and the realizability of tax loss carryforwards. Valuation allowances related to deferred tax assets can be impacted 
by changes in tax laws, changes in statutory tax rates and future taxable income levels. If the Company were to determine that it would be able to 
realize its deferred tax assets in the future in excess of the net carrying amounts, it would decrease the recorded valuation allowance through an 
increase to income in the period in which that determination is made. Due to the history of losses the Company has generated in the past, the 
Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can be realized as of December 31, 
2013 and 2012, respectively. Accordingly, the Company has recorded a full valuation allowance on its deferred tax assets for these years.  

At December 31, 2013 , the Company had a valuation allowance against net deferred tax assets of $21.0 million . The Company reviews on a 
quarterly basis its conclusions about the appropriate amount of its deferred income tax asset valuation allowance. In the ordinary course of business 
there is inherent uncertainty in quantifying the Company’s income tax positions. The Company assesses its income tax positions and records tax 
benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at the 
reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company has recorded the highest 
amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge 
of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be realizable, no tax benefit has 
been recognized in the financial statements.  

The Company includes interest and penalties with income taxes in the accompanying statement of operations. All of the Company’s net operating 
losses and research credit carryforwards prior to 2013 are subject to tax authority adjustment and all years after 2009 are still subject to tax authority 
examinations. The Company is currently not subject to any income tax audit examinations by tax authorities in any jurisdictions including U.S. 
federal, state and local or foreign countries.  

Foreign currency translation  

The functional currency of the Company’s foreign subsidiaries is the U.S. dollar.  Accordingly, monetary assets and liabilities in non-functional 
currency of these subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are 
remeasured using average exchange rates for the period, except for costs related to those consolidated balance sheet items that are remeasured using 
historical exchange rates. The resulting remeasurement gains and losses are included in the Company’s consolidated statements of operations. 
Translation gains and losses have not been significant to date.  

Segments  

Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the 
Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating 
decision maker is the Chief Executive Officer. The Company has two operating segments which are both reportable business segments: (i) Product; 
and (ii) Service.  

Comprehensive income (loss)  

59  

 
 
Table of Contents  

Before 2012, there were no components of comprehensive income which were excluded from net income (loss). For the years ended December 31, 
2013 and 2012 , the Company had small unrealized gains on available-for-sale securities. There were no other components within other 
comprehensive income for the years ended December 31, 2013 or 2012 .  

Related party transactions  

During the years ended December 31, 2013 and 2012 , the Company billed a related party, the University of Chicago Medical Center (“UCMC”), 
$0.5 million in each year for consulting services and technology solutions. One of the Company's board members, Sharon O’Keefe, is the President 
of UCMC. These transactions were recorded at arms-length prices. There were no material related party transactions for UCMC in the year ended 
2011 . During the year ended December 31, 2013 the Company billed a related party, the Hewlett-Packard Company, approximately $9,200 for 
software and support, at arms’ length prices. Through July of 2013, John N. McMullen, one of the Company’s directors, served as Treasurer & 
Senior Vice President at Hewlett-Packard. There were no material related party transactions for Hewlett-Packard in the years ended December 31, 
2012 and 2011 .  

Recent accounting pronouncements  

In July 2013, the 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 is effective for the Company's first quarter of 2014, applied 
prospectively. The Company has the option to apply the rule retrospectively and early adoption is permitted. Adoption of this standard is not 
expected to impact the financial position or results of operations of the Company.  

2.   Fair value of financial instruments 

The carrying values of the Company’s cash and cash equivalents and short-term investments approximate their fair value due to their short-term 
nature. 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 years ended December 31, 2013 , 2012 
and 2011 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 table below summarizes the Company’s assets that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of 
December 31, 2013 and 2012 , respectively. There were no liabilities measured at fair value on a recurring basis for these dates.

The Company has determined that the unrealized losses on its short-term investments as of December 31, 2013 do not constitute an "other than 
temporary impairment". There were no unrealized loss positions as of December 31, 2012. The unrealized losses for the short-term investments as 
of December 31, 2013 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.

4.   Income (loss) per share 

For fiscal years preceding 2013, basic and diluted net income (loss) per common share is presented in conformity with the two-class method 
required for participating securities. Immediately prior to the completion of the Company’s IPO on April 2, 2012, holders of Series A through 
Series F preferred stock were each entitled to receive non-cumulative dividends at the annual rate of 8%  per share per annum, respectively, payable 
prior and in preference to any dividends on any shares of the Company’s common stock. In the event a dividend is paid on common stock, the 
holders of preferred stock were entitled to a proportionate share of any such dividend as if they were holders of common stock (on an as-if 
converted basis). The holders of the preferred stock did not have a contractual obligation to share in the losses of the Company. The Company 
considered its preferred stock to be participating securities. Additionally, the Company considers shares issued upon the early exercise of options 
subject to repurchase and unvested restricted shares to be participating securities as the holders of these shares have a nonforfeitable right to 
dividends. In accordance with the two-class method, earnings allocated to these participating securities and the related number of outstanding shares 
of the participating securities, which include contractual participation rights in undistributed earnings, have been excluded from the computation of 
basic and diluted net income (loss) per common share.  

Under the two-class method, net income (loss) attributable to common stockholders is determined by allocating undistributed earnings, calculated 
as net income less income attributable to participating securities between common stock and participating securities. In computing diluted net 
income (loss) attributable to common stockholders for calculation of diluted net income (loss) per share, undistributed earnings are re-allocated to 
reflect the potential impact of dilutive securities. Basic net income (loss) per common share is computed by dividing the net income (loss) 
attributable to common stockholders by the weighted-average number of common shares outstanding during the period. All participating securities 
are excluded from basic weighted-average common shares outstanding. Diluted net income per share attributable to common stockholders is 
computed by dividing the net income attributable to common stockholders for calculation of diluted net income (loss) per share by the weighted-
average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock 
options using the treasury stock method.  

For fiscal year 2013, the two-class method is not applicable due to the net loss, which must be attributed entirely to the common shareholders. 
Additionally, as of December 31, 2013 , there are only 26,463 of participating securities, consisting of repurchasable shares issued from early 
exercise of options and unvested restricted shares, so that the future effect of participating securities would generally be immaterial, even in years 
with net income.

The Company had $5.6 million of goodwill for each of the years as of December 31, 2013 and 2012 . Goodwill is tested for impairment at the 
reporting unit level at least annually or more often if events or changes in circumstances indicate the carrying value may not be recoverable. The 
Company has two reporting units: Product and Service; as of December 31, 2013 all of the Company's goodwill resides in the Product reporting 
unit. The Company performed the annual required test of impairment of goodwill as of September 30, 2013.  For both 2013 and 2012, the Company 
used the qualitative assessment permitted under authoritative accounting guidance. Among the qualitative factors considered were changes since the 
prior impairment in the following: industry and competitive environment, business strategy, product mix, buyer and supplier bargaining power, 
potential market size, consistency in operating margins and cash flows, change in reporting unit / product life cycle stage and earnings quality and 
sustainability. The Company’s annual impairment test did not indicate impairment at any of its reporting units. No impairment was recorded in 
2013 , 2012 or 2011 . As of December 31, 2013 , no changes in circumstances indicate that goodwill carrying values may not be recoverable.

Triggering event for impairment analysis  

During the three months ended June 30, 2013, the Company experienced a 37% one-day decrease in share price following an earnings 
announcement on May 2, 2013 of below-guidance results for the first quarter of 2013 and reduced forward guidance for fiscal year 2013, which was 
considered a triggering event for further inquiry for both goodwill and the acquired intangibles. A "Step Zero" impairment assessment for goodwill 
and intangible assets was performed as part of this analysis, with the conclusion of no impairment of goodwill or intangibles. As of the September 
30, 2013 annual assessment date, there were no changes in circumstances indicating that the carrying values of goodwill or acquired intangibles 
may not be recoverable.  

Intangible assets  

The fair values for acquired intangible assets were determined by management relying in part on valuations performed by independent valuation 
specialists. Acquisition-related intangible assets are amortized over the life of the assets on an accelerated basis that approximates the expected 
economic benefit of the assets. This assumption results in amortization that is higher in earlier periods of the useful life. To date there has been no 
impairment of the Company's intangible assets. The estimated useful lives and carrying value of acquired intangible assets are as follows:

The Company provides for the estimated costs of hardware warranties at the time the related revenue is recognized. Costs are estimated based on 
historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific 
hardware warranty includes parts and labor over a period generally ranging from one to three years. The Company provides no warranty for 
software. The Company regularly re-evaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as 
necessary.

The Company enters into non-cancelable purchase commitments with its third-party manufacturer whereby the Company is required to purchase 
any inventory held by the third-party manufacturer that have been purchased by them based on confirmed orders from the Company. As of 
December 31, 2013 and 2012 , approximately $3.1 million and $4.1 million , respectively, of raw material inventory was purchased and held by the 
third-party manufacturer which was subject to such purchase requirements.  

Leases  

The Company leases office space for its headquarters and subsidiaries under non cancelable operating leases, which will expire between April 2014 
and April 2017. The San Jose, California headquarters lease ends March 31, 2016, with a single three-year extension option at rates approximating 
then-fair market value. Total rent expense for the years ended December 31, 2013 , 2012 and 2011 was $2.0 million , $1.9 million and $1.7 million , 
respectively. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not 
paid.

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 response to the current complaints is 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, we 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.  

8.   Common Stock and Share-based Compensation 

The Company’s certificate of incorporation, as amended, authorizes the Company to issue 100 million shares of $0.0003 par value common stock.

Incentive stock option plans  

The Company has three equity incentive plans: the 2000 Stock Option Plan (the “2000 Plan”), the 2006 Stock Option Plan (the “2006 Plan”) and 
the 2012 Stock Option Plan (the “2012 Plan”). On March 26, 2012, all shares that were reserved under the 2006 Plan but not subject to outstanding 
awards became available for grant under the 2012 Plan. No additional shares will be issued under the 2006 Plan. The 2000 Plan terminated in 
March 2010 and no additional shares will be issued under this plan. All options currently outstanding under the 2000 Plan and the 2006 Plan 
continue to be governed by the terms and conditions of those plans. Under the 2012 Plan, the Company has the ability to issue incentive stock 
options (“ISOs”), stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance awards and stock bonuses. The ISOs will 
be granted at a price per share not less than the fair value at date of grant. Options granted to new hires generally vest over a 4 -year period with 
25% vesting at the end of one year and the remaining vest monthly thereafter, options granted as merit awards generally vest monthly over a four-
year period. Options granted generally are exercisable up to 10 years . As of December 31, 2013 , there were 328,519 shares remaining available for 
future issuance under the 2012 Plan.  

Early exercise of stock options  

The Company typically allows employees to exercise options granted under the 2000 and 2006 Plans prior to vesting. The unvested shares are 
subject to the Company’s repurchase right at the original purchase price. The proceeds initially are recorded as an accrued liability from the early 
exercise of stock options and reclassified to common stock as the Company’s repurchase right lapses. At December 31, 2013 , 2012 and 2011 , 
there were unvested shares in the amount of 14,360 , 48,260 and 112,967 , respectively, which were subject to repurchase at an aggregate price of 
$0.1 million , $0.2 million and $0.4 million , respectively.

At December 31, 2013 , there was $8.2 million of unrecognized net compensation cost related to options which is expected to be recognized over a 
weighted-average period of 2.5 years The Company did not grant non-employee options in either of the years ended December 31, 2013 or 2012.  

Using the Black-Scholes option-pricing model, the weighted-average grant-date fair value of options granted to employees during the years ended 
December 31, 2013 , 2012 and 2011 was $7.34 per share, $10.19 per share, and $3.30 per share, respectively. Further information regarding the 
value of employee options vested and exercised during the years ended December 31, 2013 , 2012 and 2011 is set forth below.

The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the 
following major inputs: the estimated fair value of the underlying common stock, the expected term of the option, the expected volatility of the 
underlying common stock over the expected life of the option, the risk-free interest rate and expected dividend yield. The following assumptions 
were used for each respective period for employee stock-based compensation: 

Expected Term (in years)  
Volatility  
Risk-free interest rate  
Dividend yield  

2013  
5.38 - 5.43  
46.7% - 48.1%  
0.81% - 1.80%  
0.0%  

Years ended December 31,  
2012

47.9% - 48.7%  
0.72% - 1.03%

2011  
5.49 - 5.73  
44.7% - 47.6%  
0.98% - 2.48%  
0.0%  

The computation of expected term is based on the historical exercise and forfeiture behavior of the Company’s employees, giving consideration to 
the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. For the expected term so 
determined, the risk-free rate is the U.S. Treasury Rate for that term on the grant date. The Company's expected common stock price volatility is 
based on the historical volatility of a peer group of publicly-traded companies, using the same expected term. The peer group was selected based on 
industry and market capitalization data. The Company assumes the dividend yield to be zero , as the Company has never declared or paid dividends 
and does not expect to do so in the foreseeable future.  

Employee Stock Purchase Plan  

In March 2012, the Company's board of directors and stockholders approved the 2012 Employee Stock Purchase Plan (the “ESPP”). The ESPP 
allows eligible employees to purchase shares of the Company's common stock at a discount through payroll deductions of up to 15% of their 
eligible compensation, subject to any plan limitations. The ESPP provides for six -month offering periods, except for the first offering period which 
was for 11 months. Additionally, in April 2013, the Company's compensation committee determined that following the February 15, 2013 six-
month offering period, the next offering period under the ESPP would last for three months (commencing August 15, 2013 and expiring on 
November 14, 2013) and, following the expiration of such offering period, offering periods thereafter will commence on November 15, 2013, and 
May 15, 2014 and so on, each consisting of a single six-month purchase period.   

At the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company's common 
stock on the first trading day of the offering period or on the last day of the offering period. During the year ended December 31, 2013 , employees 
purchased 215,039 shares of common stock at an average purchase price of $13.92 . No shares were purchased under the plan in 2012. As of 
December 31, 2013 , 193,920 shares remained available for future issuance under the ESPP.  

The Company uses the Black-Scholes option-pricing model to calculate the fair value of periodic ESPP offerings on their offer date. The following 
assumptions were used for each respective period for the ESPP: 

Expected Term (in years)  
Volatility  
Risk-free interest rate

Restricted Stock Awards and Restricted Stock Units  

In 2012, the Company began incorporating restricted stock awards and RSUs as an element of its compensation plans. In February 2012, the 
Company granted certain of its directors restricted stock awards that vest 50% on the first anniversary of the grant, and 50% on the second 
anniversary of the grant. In May 2012, the Company granted certain employees RSUs, which vest one third on the first anniversary of the grant, one 
third on the second anniversary of the grant and one third upon the third anniversary of the grant.

At December 31, 2013 , there was $16,000 of unrecognized net compensation cost related to restricted stock awards which is expected to be 
recognized over a weighted-average period of 0.1 years. At December 31, 2013 , there was $10.8 million of unrecognized net compensation cost 
related to RSUs, which is expected to be recognized over a weighted-average period of 2.1 years.  

Non-Employee Stock-Based Compensation  

While the Company granted no options to non-employees during the years ended December 31, 2013 and 2012 , the Company granted 67,916 
options to non-employees during the year ended December 31, 2011 . All options granted to non-employees during 2011 were fully vested on the 
date of grant. Stock-based compensation expense related to stock options granted to non-employees is recognized as the stock option vests, or if 
fully vested, on the date of grant.  

For stock options issued to non-employees with specific performance criteria, the Company makes a determination at each balance sheet date 
whether the performance criteria are probable of being achieved. Compensation expense is recognized at the time it is determined that it is probable 
the performance criteria will be met. For the November 2010 ExperiaHealth acquisition, the entire $0.1 million consideration to the seller was in the 
form of revenue milestone performance options, with 41,666 options for 2010 revenue performance and another 41,666 options for 2011. Of the 
first tranche, 35,452 options ultimately vested, and the 2011 performance options for 41,666 shares vested entirely in March 2012. Under 
accounting guidance for acquisitions, such contingent consideration is recorded initially as a liability, and adjusted to fair value at each reporting 
date through net income, until vested. The 2012 pricing model assumptions below refer not to new non-employee grants in 2012, but to revaluation 
of the 2011 performance options. During the first quarter of 2012, the fair value of these increased from $419,000 to $448,000 , resulting in 2012 
stock-based compensation expense of $29,000 . The entirely liability was then reclassified back to December 31, 2011 as equity.  

The fair value of the stock options granted to non-employees was calculated using the Black-Scholes option-pricing model with the following 
assumptions:  

Expected Term (in years)  
Volatility  
Risk-free interest rate  
Dividend yield

0.0%  

For the years ended December 31, 2013 , 2012 and 2011 , the Company recognized expenses of approximately zero , $29,000 and $907,000 , 
respectively, related to these options.  

Allocation of Stock-Based Compensation Expense  

Stock-based compensation expense is recognized based on a straight-line amortization method over the respective vesting period of the award and 
has been reduced for estimated forfeitures. The Company estimated the expected forfeiture rate based on its historical experience, considering 
voluntary termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent the 
Company’s actual forfeiture rate is different from the estimate, the stock-based compensation expense is adjusted accordingly.  

The following table presents the stock-based compensation allocation of expense (both for employees and non-employees):

Prior to the April 2012 IPO, outstanding warrants to purchase preferred stock were classified as liabilities, which were adjusted to fair value at each 
reporting period until the earlier of their exercise or expiration or the completion of a liquidation event, including the completion of an initial public 
offering, at which time the preferred stock warrant liability automatically converted into a warrant to purchase shares of common stock and was 
reclassified to stockholders’ equity (deficit). The Company recorded an expense in other income (expense), net of zero , $1.6 million and $1.0 
million for the years ended December 31, 2013 , 2012 and 2011 , respectively, to reflect the change in the fair value of the outstanding preferred 
stock warrants. Since April 2012, the converted common stock warrants are classified within stockholder's equity (deficit) because they are 
considered to be "indexed to the entity's own stock".  

The holders of all the common stock warrants described above may undertake a cashless conversion of the warrant, in whole or in part, in lieu of 
exercising the warrant. The number of shares to be issued in such a conversion shall be determined by dividing (a) the aggregate fair market value 
of the shares issuable upon the exercise of the warrant minus the aggregate warrant price of such shares by (b) the fair market value of one share at 
the time of conversion.  

During the year ended December 31, 2013 , holders of common stock warrants exercised 34,142 shares for cash proceeds of $0.2 million . There 
were no cash exercises in the prior twelve-month period. During the year ended December 31, 2012 , holders of common stock warrants net 
exercised warrants for the purchase of 108,155 shares and received 78,487 shares. There were no such cashless exercises in the current twelve 
month period.  

At December 31, 2013 warrants to purchase 44,491 shares of common stock, each with exercise price of $6.61 , were outstanding and expire in 
October 2015.  

9.   Segments 

The Company has two operating segments which are both reportable segments: (i) Product; and (ii) Service, which are comprised of the Company’s 
and its wholly-owned subsidiaries’ results from 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 Company determines its valuation allowance on deferred tax assets by considering both positive and negative evidence in order to ascertain 
whether it is more likely than not that deferred tax assets will be realized. Realization of deferred tax assets is dependent upon the generation of 
future taxable income, if any, the timing and amount of which are uncertain. Due to the history of losses the Company has generated in the past, the 
Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can be realized as of December 31, 
2013 ; accordingly, the Company has recorded a full valuation allowance on its deferred tax assets.  

The Company’s valuation allowance decreased by $0.2 million and $1.5 million for the years ended December 31, 2013 and 2012 , respectively. 
The changes in the valuation allowances were primarily due to the addition of loss carryforwards.  

At December 31, 2013 , the Company had $49.6 million and $37.5 million , respectively, of federal and state net operating loss carryforwards. 
Included in the gross amount, approximately $27.2 million of net operating loss is created by excess stock option deduction. A credit to APIC will 
be recorded when the excess stock option deduction reduces the income tax payable.  

The federal net operating loss carryforward begins expiring in 2015, and the state net operating loss carryforward began expiring in 2014, if not 
utilized.  

In addition, the Company has federal research and development tax credits carryforwards of approximately $1.7 million and state research and 
development tax credit carryforwards of approximately $2.5 million . The federal credit carryforwards begin expiring 2021 and the state credits 
carry forward indefinitely . The Internal Revenue Code (IRC) contains provisions which limit the amount of net operating loss (NOL) and research 
credit carryforwards that can be used in any given year if a significant change in ownership has occurred. During the year, the Company determined 
that prior changes in ownership as defined under IRC Section 382 had occurred, resulting in a reduction in the Company's NOL and credits 
carryovers for amounts which will expire unutilized due to these limitations. Accordingly, the Company decreased its deferred tax asset and 
corresponding valuation allowance by $2.5 million to reflect the reduction of these carryovers. As of December 31, 2013, $12.8 million of the

Company's NOL carryovers and $0.5 million of credit carryovers are subject to an annual $0.6 million limitation, of which $7.5 million NOLs 
would be available to offset future taxable income in the twenty-year carryforward period.

As a result of the Company’s historic losses and related valuation allowances, the Company has recorded the uncertain tax amounts above entirely 
as reductions to deferred tax assets which are subject to a full valuation allowance in its consolidated balance sheet. The Company recognizes 
interest and penalties relating to uncertain tax positions in income tax expense. For the years ended December 31, 2013 and 2012 , penalties and 
interest were $26,000 and zero , respectively. As the Company is not currently under examination, it is reasonable to assume that the balance of 
gross unrecognized tax benefits will likely not change in the next twelve months.  

The Company files income tax returns in the United States on a federal basis and in various states. The Company is not currently under any 
international or any United States federal, state and local income tax examinations for any taxable years. All of the Company’s net operating losses 
and research credit carryforwards prior to 2013 are subject to tax authority adjustment and all years after 2008 are still subject to the tax authority 
examinations.  

The Company has not provided for U.S. federal and foreign withholding taxes on $0.9 million of the Company’s non-U.S. subsidiaries’ 
undistributed earnings as of December 31, 2013 , since the Company intends to reinvest this amount outside the U.S. indefinitely. The tax impact of 
repatriating these earnings is not practical to compute.

Business Acquisition  

On January 13, 2014 , the Company acquired certain assets of mVisum, Inc., an innovative provider of alarm management technology solutions for 
health systems, for $3.5 million cash in an asset purchase transaction. This new acquisition specifically addresses communications breakdowns 
caused by alarm fatigue, which has become a top patient safety concern and a regulatory priority.  

Alarm fatigue occurs when clinicians receive too many alarms during a given shift with too little context or data to assess the urgency or criticality 
of the alarms, which can negatively affect patient safety. The mVisum technology platform provides images and data, including waveforms like 
electrocardiograms, with the alarm notification directly to the physician, nurse or other members of the care team so that they can prioritize their 
response based on context and important information.

The acquisition is expected to align well with the Company's strategic vision of being the leader in integrated, intelligent communications solutions 
for healthcare and other mission-critical environments.  

The Company is currently completing the preliminary purchase price allocation and expects the majority of the purchase consideration will be 
allocable to intangibles and goodwill.

Evaluation of Disclosure Controls and Procedures  

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports filed or submitted under the 
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's 
rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information 
required to be disclosed in reports filed under the Exchange Act is accumulated and communicated to management, including principal executive 
and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. 
There are inherent

limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention 
or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance 
of achieving their control objectives.  

As of December 31, 2013 we have carried out an evaluation under the supervision of, and with the participation of our management, including our 
Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as 
defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on our evaluation, our Chief Executive Officer and Chief Financial Officer 
concluded that our disclosure controls and procedures were effective as of December 31, 2013 .  

Management's Report on Internal Control Over Financial Reporting  

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) 
under the Exchange Act). Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on 
the criteria set forth in the original 1992 version of the Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission ("COSO"). Based on the assessment, management has concluded that our internal control over 
financial reporting was effective as of December 31, 2013 based on these criteria. This Annual Report on Form 10-K does not include an attestation 
report of our registered public accounting firm on our internal control over financial reporting due to an exemption established by the JOBS Act for 
"emerging growth companies".  

Changes in Internal Control over Financial Reporting  

Except for the ongoing implementation of a sophisticated ERP system, there was no change in our internal control over financial reporting which 
occurred during the three months ended December 31, 2013 which has materially affected, or is reasonably likely to materially affect, our internal 
control over financial reporting.
