PART I

Item 1.  Business.

The Company

Our portfolio of intellectual property is the foundation of our business model.  We currently own 20 patents in the United States and 32 foreign patents, as well as several pending U.S. and foreign patent applications.  Our patent portfolio is primarily focused on securing real-time communications over the Internet, as well as related services such as the establishment and maintenance of a secure domain name registry.  Our patented methods also have additional applications in operating systems and network security.  We have submitted  a declaration with the 3rd Generation Partnership Project, or 3GPP, identifying a group of our patents and patent applications that we believe are or may become essential to certain developing specifications in the 3GPP LTE, SAE project. We have agreed to make available a non-exclusive patent license under fair, reasonable and non-discriminatory terms and conditions, with compensation, or FRAND, to 3GPP members desiring to implement the technical specifications identified by us. We believe that we are positioned to license our essential security patents to 3GPP members as they move into 4G.

We have an ongoing Gabriel Licensing Program under which we offer licenses to our patent portfolio, technology and software, including our secure domain name registry service, to domain infrastructure providers, communication service providers as well as to system integrators. Our Gabriel Connection TechnologyTM License is offered to OEM customers who want to adopt the GABRIEL Connection Technology™ as their solution for establishing secure connections using secure domain names within their products.  We have developed GABRIEL Connection Technology™ Software Development Kit (SDK) to assist with rapid integration of these techniques into existing software implementations with minimal code changes and include object libraries, sample code, testing and quality assurance tools and the supporting documentation necessary for a customer to implement our technology. Customers who want to develop their own implementation of the VirnetX patented techniques for supporting secure domain names, or other techniques that are covered by our patent portfolio for establishing secure communication links, can purchase a patent license. The number of patents licensed, and therefore the cost of the patent license to the customer, will depend upon which of the patents are used in a particular product or service. These licenses will typically include an initial license fee, as well as an ongoing royalty.

We intend to license our patent portfolio, technology and software, including our secure domain name registry service, to domain infrastructure providers, communication service providers as well as to system integrators.  We believe that the market opportunity for our software and technology solutions is large and expanding as secure domain names are now an integral part of securing the next generation 4G/LTE wireless networks. We also believe that all 4G mobile devices will require unique secure domain names and become part of a secure domain name registry.

In connection with the settlement of our lawsuit against Microsoft Corporation in 2010, Microsoft became our first licensee.  Pursuant to the Settlement and License Agreement between ourselves and Microsoft, Microsoft paid us $200 million, which has been recognized as gain on settlement and Microsoft was granted a worldwide, irrevocable, nonexclusive, non-sub licensable fully paid up license for our patents for Microsoft products. We have also signed Patent License Agreements with Aastra USA, Inc. Mitel Networks Corporation, NEC Corporation and NEC Corporation of America, Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc. to license certain of our US patents, for a one-time payment and an ongoing royalty for all future sales through the expiration of the licensed patents with respect to certain current and future IP-encrypted products. We intend to seek further license of our technology, including our GABRIEL Connection Technology™ to enterprise customers, developers and original equipment manufacturers, or OEMs, of chips, servers, smart phones, tablets, e-Readers, laptops, net books and other devices, within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets including 4G/LTE. We have published our royalty rates and guidelines on our website. All existing licenses have adhered to these guidelines and have met or exceeded these rates and we will use these rates and guidelines in all future license negotiations.

Our employees include the core development team behind our patent portfolio, technology and software.  This team has worked together for over ten years and is the same team that invented and developed this technology while working at Science Application International Corporation, or SAIC.  SAIC is a FORTUNE 500® scientific, engineering and technology applications company that uses its deep domain knowledge to solve problems of vital importance to the nation and the world, in national security, energy and the environment, critical infrastructure and health. The team has continued its research and development work started at SAIC and expanded the set of patents we acquired in 2006 from SAIC into a larger portfolio with 52 issued U.S. and foreign patents and numerous pending U.S. and foreign patents applications. This portfolio now serves as the foundation of our licensing business and planned service offerings and is expected to generate the majority of our future revenue in license fees and royalties. We intend to continue our research and development efforts to further strengthen and expand our patent portfolio.  Please see Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Operations – Research and Development Expenses for a description of our research and development expenses for the past three fiscal years.

We intend to continue using an outsourced and leveraged model to maintain efficiency and manage costs as we grow our licensing business by offering incentives to early licensing targets or asserting our rights for use of our patents.  We also intend to expand our design pilot in participation with leading 4G/LTE companies (domain infrastructure providers, chipset manufacturers, service providers and others) and build our secure domain name registry.

Industry Overview

We believe that the Internet is an evolving, rich and complex medium used by individuals and businesses to conduct commerce, share information and engage in real-time communications including email, text messaging, IM, and voice and video calls. We believe that users have grown accustomed to having broadband access wherever they go, and not just at home or in the office. Users can browse the Internet or send e-mails using their mobile broadband enabled notebooks, replace their fixed DSL modems with mobile broadband modems or other devices, and send and receive video or music using 3G phones. We believe that Long Term Evolution, or LTE, will further advance a transition from the cellular 3G services to an all internet packet, or "IP", based network that can provide mobile data access speeds closer to fixed DSL speeds and allow for more bandwidth intensive applications like interactive TV, mobile video blogging, advanced games or professional services. Session initiation protocol, or SIP, was developed to enable the convergence of voice and data networks and today is the predominant industry standard for establishing multimedia communications over the Internet such as voice, video, instant messaging, presence information and file transfer. SIP, XMPP and other real-time collaboration protocols use DNS lookup as the primary means of connecting Internet devices. However, because these protocols use "open architecture", we believe that they are inherently unsecure.

We also believe that many enterprises have concluded that security provided to communication by way of an optional add-on solution is less secure than security that can be provided by upgrading core information technology, or "IT", infrastructure (systems, networks, and management) with integrated security. We believe that, because of the complexity of today's networks and the requirement to connect users from any location at any time on any device, enterprises are reevaluating numerous parts of their technology systems, including but not limited to software solutions for smartphones, routers and switches with integrated security, massive security appliances for data centers, cloud-based security services and security solutions for virtualized environments and public and private clouds. The portions of the IP-telephony, mobility, fixed-mobile convergence and unified communications markets that could benefit from our software and technology solutions are forecasted by Infonetics and our internal estimates to grow from approximately $128 billion of worldwide revenues in 2010 to approximately $226 billion by 2015, representing a compound annual growth rate, or CAGR, of approximately 12%. We believe that this growing trend represents a significant opportunity for us to license our technology and software, and establish our secure domain name registry.

We also believe that various enterprises have concluded that optional add-on solution, and enterprises everywhere are currently upgrading core IT infrastructure (systems, networks, and management) to integrate security into everything. Because of the complexity of today’s networks, and the requirement to connect users from any location at any time on any device, enterprise IT is having to reevaluate everything from software solutions for smartphones to routers and switches with integrated security, massive security appliances for data centers, cloud-based security services, and security solutions for virtualized environments and public and private clouds. The portions of the IP-telephony, mobility, fixed-mobile convergence and unified communications markets that could benefit from our software and technology solutions are forecasted by Infonetics and our internal estimates to grow from approximately $128 billion of worldwide revenues in 2010 to approximately $226 billion by 2015, representing a compound annual growth rate, or CAGR, of approximately 12%.  We believe that this growing trend represents a significant opportunity for VirnetX to license its technology and software, and establish its secure domain name registry.

IP Telephony – VoIP, Telepresence and Video Conferencing

IP telephony includes technologies that use Internet Protocol’s packet-switched connections to exchange voice, fax, and other forms of information traditionally carried over the dedicated circuit-switched connections of the public switched telephone network, or PSTN.  The adoption of IP telephony has helped businesses significantly lower network operating costs by using a common network for voice and data. As the workforce becomes increasingly dispersed, mobile features enabled by Internet protocol-based communications such as presence, unified messaging, peer-to-peer applications, find me/follow me, white-boarding and document sharing have become more commonplace.  However, the development of the related security infrastructure has lagged behind, leaving next-generation networks vulnerable to a multitude of threats including man-in-middle, eavesdropping, domain hijacking, distributed denial of service, or DDoS, spam over Internet telephony, or SPIT, and spam over instant messaging, or SPIM.  These threats continue to highlight the need for securing next-generation networks.  As the use of IP telephony systems extends beyond the boundaries of an organization’s private network, security is likely to become an even bigger concern.  Worldwide revenue from IP telephony products like IP-PBX including IP phones, service provider VoIP and IMS equipment, VoIP gateways, Enterprise Telepresence and Video Conferencing for businesses is forecasted by Infonetics and our internal estimates to grow from approximately $30 billion in 2010 to approximately $59 billion in 2015, representing a CAGR of approximately 15%.  We believe our unique and patented solution provides the robust security platform required for providing on-demand secure communication links between enterprises intending to communicate securely without manually configuring the connections.  We believe a standard security solution such as ours will further accelerate the adoption of IP telephony products in the market and allow enterprises to take full advantage of these rich content applications and real-time communications over the Internet, thereby significantly increasing their return on investment.

Unified Communications

We believe that the need to enhance productivity is rapidly increasing demand for the management of and instant access to real-time information. We believe that mobile collaboration, instant Internet access and the ability to conduct business whether inside or outside of the office, are high priorities. We also believe that the ability to establish multiple secure simultaneous network connections and provide IP sessions with security and encryption will be critical to widespread deployment of next-generation networks. However, one possible shortcoming of this new communications environment is that the various modes of communication operate independently from one another and do not integrate easily, if at all. We believe that the number of individual points of contact in these environments will grow and that as a result, communication will become more sophisticated and increasingly vulnerable.

An array of communication methodologies integrated into a single communications experience is often referred to as unified communications. We believe that unified communications have higher utility and can increase productivity for users. The basic components of unified communications include: a directory for storing addresses, various modes of communication with each user/contact (desk phone, mobile phone, 1M, etc.), message storage for all messages regardless of communication method and secure presence of a user's status for each mode of communication (available, away, busy, etc.). Worldwide unified communications market generated approximately $462 million in revenue in 2010 and is forecasted to grow rapidly over the next few years generating approximately $1.04 billion in revenue in 2015, representing a CAGR of approximately 11%. We believe the growth in unified communication products may not reach its full potential due to the lack of transparent and seamless security as users hesitate to place their presence information online for all to see and as organizations block access due to the lack of credentials verified by a neutral third party. We believe that our solutions help address these concerns and should enable significant growth in the unified communications market.

IP Mobility-LTE, Fixed-Mobile Convergence

We believe that telecommunication markets are rapidly changing and presenting new challenges to the equipment and service providers, including but not limited to increasing user demand for mobile, always-on connections with multiple devices. We also believe that traffic growth, video acceleration, cloud services and a rapidly growing number of subscribers challenge currently available network architectures and that, because of this, service providers and carriers will eventually use a single network for fixed and mobile communications, private/premium communications and Internet access, in spite of the difficulties involved challenging their business models and forcing the consideration of new network architectures. We believe that LTE technology will deliver users the benefits of faster data speeds and new services by creating a new radio access technology that's optimized for IP-based traffic and offers operators a simple upgrade path from 3G networks. Smartphones are multi-functional devices that handle a wide variety of business-critical applications and support increasingly complex functions including enhanced data processing, Internet access, e-mail access, calendars and scheduling, contact management and the ability to view electronic documents. Users have continual access to these applications while on the move making them an increasingly essential business tool for the mobile worker. These devices enable mobile workers to have similar functionality inside or outside the office thereby increasing employee efficiency. However, it is critical that this mobile environment have the same level of security as an enterprise's internal network. Fixed-mobile convergence is an environment where wired and wireless phones work together with Internet Protocol to deliver services (voice, video, data and combinations thereof) uniformly across multiple access networks, including, among others, WiMAX, WiFi cellular and fixed. Worldwide revenue from IP mobility products like smartphones and mobile data cards, femtocell equipment, rich communication devices and services is expected to grow from approximately $98 billion in 2010 to approximately $166 billion by 2015, representing a CAGR of approximately 11%. We believe in order to realize the full functionality of IP mobility, several challenges including security must be overcome. When users are mobile, connections and data need to cross multiple network boundaries, each of which poses a security threat. Wireless networks may be threatened or compromised by rogue users who enter through (insecure wireless access points. We believe that providing authenticated access to the wireless networks and enterprise applications through the wireless domain are important requirements and represent a significant market opportunity for our patented technology and secure domain names to provide users fully authenticated secure access on a "zero-click" or "single-click" basis.

License and Service Offerings

We plan to offer a diversified portfolio of license and service offerings focused on securing real-time communications over the Internet, including:

● VirnetX technology licensing: Customers who want to develop their own implementation of the VirnetX code module for supporting secure domain names, or who want to use their own techniques that are covered by our patent portfolio for establishing secure communication links, will purchase a technology license.  We anticipate that these licenses would typically include an initial license fee, as well as an ongoing royalty.  We expect that these licenses will include a one-time delivery of Gabriel software development kit including object libraries, sample code, testing and quality assurance tools and the supporting documentation necessary for a customer to implement of the techniques we have developed.

● GABRIEL Connection Technology™ Software Development Kit or SDK: OEM customers who want to adopt the GABRIEL Connection Technology™ as their solution for establishing secure connections using secure domain names within their products will purchase an SDK license.  The software development kit consists of object libraries, sample code, testing and quality assurance tools and the supporting documentation necessary for a customer to implement our technology.  These tools are comprised of software for a secure domain name connection test server, a relay test server and a registration test server.  We expect that customers would pay an up-front license fee to purchase an SDK license and a royalty fee for every product shipped with the embedded VirnetX code module.

● Secure domain name registrar service: Customers, including service providers, telecommunication companies, ISPs, system integrators and OEMs could purchase a license to our secure domain name registrar service.  We would provide the software suite and technology support to enable such customers to provision devices with secure domain names and facilitate secure connections between registered devices.  This suite includes the following server software modules:

● Registrar server software: We anticipate that our registrar server software would enable customers to operate as a secure domain name registrar that provisions devices with secure domain names.  The registrar server software is designed to provide an interface for our customers to register new virtual private domains and sub-domain names.  This server module must be enrolled with the VirnetX secure domain name master registry to obtain its credentials before functioning as an authorized registrar.

● Connection server software: We anticipate that our connection server software would allow customers to provide connection services to enrolled devices.  The connection services include registration of presence information for authenticated users and devices, presence information query request services, enforcement of policies and support for communication with peers behind firewalls.

● Relay server software: We anticipate that our relay server software would allow customers to dynamically maintain connections and relay data to private IP addresses for network devices that reside behind firewalls.  Secure domain name registrar service customers will enter into a technology licensing and revenue sharing agreement with VirnetX whereby we will typically receive an up-front licensing fee for the secure domain name registrar technology, as well as ongoing annual royalties for each secure domain name issued by the customer.

● Secure domain name master registry and connection service: As part of enabling the secure domain name registrar service, we expect that we will maintain and manage the secure domain name master registry.  This service is expected to enroll all secure domain name registrar customers and generate the credentials required to function as an authorized registrar.  It also is expected to provide connection services and universal name resolution, presence information and secure connections between authorized devices with secure domain names.

● Technical support services: We intend to provide high-quality technical support services to licensees and customers for the rapid customization and deployment of GABRIEL Connection Technology™ in an individual customer’s products and services.

Our research and development team was the team responsible for inventing the claimed subject matter of the patents that form the foundation of our technology.  This team has worked together for over ten years.  We intend to leverage this experience and continue investing in research and development and, over time, expect to strengthen and expand our patent portfolio, technology, and software.  While we are currently focused on securing real-time communications over the Internet and establishing the first and only secure domain name registry, we believe our existing and future intellectual property portfolio will extend to additional areas including, among others, network security and operating systems for fixed and mobile devices.

Customers

Pursuant to the Settlement and License Agreement between us and Microsoft, Microsoft paid us $200 million, which has been recognized as gain on settlement and Microsoft was granted a worldwide, irrevocable, nonexclusive, non-sub licensable fully paid up license for our patents for Microsoft products. We have also signed Patent License Agreements with Aastra USA, Inc. Mitel Networks Corporation, NEC Corporation and NEC Corporation of America, Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc. to license certain of our US patents, for a one-time payment and an ongoing royalty for all future sales through the expiration of the licensed patents with respect to certain current and future IP-encrypted products.

We intend to seek further license of our technology, including our GABRIEL Connection Technology™ to developers and original equipment manufacturers, or OEMs, of chips, servers, smart phones, tablets, e-Readers, laptops, net books and other devices, within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets including 4G/LTE. We have published our royalty rates and guidelines on our website. All forward moving licenses have adhered to these guidelines and have met or exceeded these rates and we will use these rates and guidelines in all future license negotiations.

Marketing and Sales

We plan to employ a leveraged, partner-oriented, marketing strategy for our technology licenses and software offerings.  We expect the marketing strategy will primarily be focused on OEMs.

We plan to directly market our domain name registry services to our service provider and system integrator customers.  We hope to leverage our relationship with SAIC to extend our offering to departments and agencies within the federal government.  SAIC is a FORTUNE 500® scientific, engineering and technology applications company that uses its deep domain knowledge to solve problems of vital importance to the nation and the world, in national security, energy and the environment, critical infrastructure, and health. We intend to build a sales force that will be responsible for managing accounts and pursuing technology licensing and sales opportunities with new customers.

Competition

We believe our technology and solutions will compete primarily against various proprietary security solutions.  We group these solutions into three main categories:

● Proprietary or home-grown application specific security solutions have been developed by vendors and integrated directly into their products for our target markets including IP-telephony, mobility, fixed-mobile convergence, and unified communications.  These proprietary solutions have been developed due to the lack of standardized approaches to securing real-time communications.  This approach has led to corporate networks that are isolated and, as a result, restrict enterprises to using these next-generation networks within the boundaries of their private network.  These solutions generally do not provide security for communications over the Internet or require network administrators to manually exchange keys and other security parameters with each destination network outside their corporate network boundary.  The cost-savings and other benefits of IP-based real-time communications are significantly limited by this approach to securing real-time communications.

● A session border controller, or SBC, is a device used in networks to exert control over the signaling and media streams involved in establishing, conducting and terminating VoIP calls.  A traditional firewall or network address translation, or NAT, device typically block information like endpoint IP addresses and port numbers required by signaling protocols, such as SIP and XMPP, to reach and communicate with their intended destination.  SBCs are used in physical networks to address these limitations and enable real-time session traffic to cross the boundaries created by firewalls and other NAT devices and enable VoIP calls to be established successfully.  However, SBCs must decrypt and analyze every single data packet for the information to be transmitted successfully, thereby preventing end-to-end encryption.  This network design results in SBCs becoming a single point of congestion on the network, as well as a single point of failure.  SBCs are also limited to the physical network they secure.

● SIP firewalls, or SIP-aware firewalls, and application layer gateways, manage and protect the traffic, flow and quality of VoIP and other SIP-related communications.  They perform real-time network address translation, dynamic firewall functions; support multiple signaling protocols, and media functionality, allowing secure interconnection and the flow of IP media streams across multiple networks.  While SIP firewalls assist in analyzing SIP traffic transmitted over the corporate network to filter out various threats, they do not necessarily encrypt the traffic.  As a result, this traffic is not entirely secure from end-to-end nor is it protected against threats like man-in-middle and eavesdropping.

Intellectual Property and Patent Rights

Our intellectual property is primarily comprised of trade secrets, patented know-how, issued and pending patents, copyrights and technological innovation.

We have a portfolio comprised of twenty (20) patents in the United States and thirty two (32) foreign patents as well as several pending U.S. and foreign patent applications.  Our portfolio includes a number of patents that describe unique systems and methods for securing real-time communications over the Internet, as well as related services such as the establishment and maintenance of a secure domain name registry.  Our software and technology solutions also have additional applications relating to operating systems and network security.

Assignment of Patents

Some of our issued patents and pending patent applications were acquired by our principal operating subsidiary, VirnetX, Inc., from Science Applications International Corporation, or SAIC, pursuant to an Assignment Agreement dated December 21, 2006, and a Patent License and Assignment Agreement dated August 12, 2005, as amended on November 2, 2006, including documents prepared pursuant to the November amendment, and as further amended on March 12, 2008. We recorded the assignment from SAIC with the U.S. Patent Office on December 21, 2006.

Key terms of these agreements are as follows:

Patent Assignment.  SAIC unconditionally and irrevocably conveyed, transferred, assigned and quitclaimed all its right, title and interest in and to the patents and patent applications, as specifically set forth on Exhibit A to the assignment document recorded with the U.S. Patent Office, including, without limitation, the right to sue for past infringement.

License to SAIC Outside the Field of Use.  On November 2, 2006, we granted to SAIC an exclusive, royalty free, fully paid, perpetual, worldwide, irrevocable, sub licensable and transferable right and license permitting SAIC and its assignees to make, have made, import, use, offer for sale, and sell products and services covered by, and to make improvements to, the patents and patent applications we acquired from SAIC, solely outside our field of use. We have, and retain, all right, title and interest to all our patents within our field of use. On March 12, 2008, SAIC relinquished the November 2, 2006, exclusive right and license outside our field of use referred to above, as well as any right to obtain such exclusive license in the future. Effective March 12, 2008, we granted to SAIC a non-exclusive, royalty free, fully paid, perpetual, worldwide, irrevocable, sub licensable and transferable right and license permitting SAIC and its assignees to make, have made, import, use, offer for sale, and sell products and services covered by, and to make improvements to, the patents and patent applications we acquired from SAIC, solely outside our field of use.

Compensation Obligations. As consideration for the assignment of the patents and for the rights we obtained from SAIC as amended, we are required to make payments to SAIC based on cash or certain other values generated from those patents.  The amount of such payments depends upon the type of value generated, and certain categories are subject to maximums and other limitations. As of June 30, 2010, we met our maximum royalty payment requirement; however, SAIC is also entitled under certain circumstances to receive a portion of the proceeds paid to us for certain acquisitions of VirnetX, from the settlement of certain patent infringement claims of ours.

Government Regulation

The laws governing online secure communications remain largely unsettled, even in areas where there has been legislative action.  It may take years to determine whether and how existing laws governing intellectual property, privacy and libel apply to online communications and media.  Such legislation may interfere with the growth in use of online secure communications and decrease the acceptance of online secure communications as a viable solution, which could adversely affect our business.

Due to the Internet’s popularity and increasing use, new laws regulating secure communications may be adopted. These laws and regulations may cover, among other things, issues relating to privacy, pricing, taxation, telecommunications over the Internet, content, copyrights, distribution and quality of products and services. We intend to comply with all new laws and regulations as they are adopted.

The U.S. government has controlled the authoritative domain name system, or DNS, root server since the inception of the Internet.  On July 1, 1997, the President of the United States directed the U.S. Secretary of Commerce to privatize the management of the domain name system in a manner that increases competition and facilitates international participation in its management.

On September 29, 2006, the U.S. Department of Commerce extended its delegation of authority by entering into a new agreement with the Internet Corporation for Assigned Names and Numbers, or ICANN, a California non-profit corporation headquartered in Marina Del Rey, California.  ICANN is responsible for managing the accreditation of registry providers and registrars that manage the assignment of top level domain names associated with the authoritative DNS root directory.  Although it is possible to create and manage other DNS root directories privately without accreditation from ICANN, the possibility of conflicting name and number assignments makes it less likely that users would widely adopt a top level domain name associated with an alternative DNS root directory provided by a non-ICANN-accredited registry service.

We are currently evaluating whether we will apply to become an ICANN-accredited registry provider with respect to one or more customized generic top-level domain (gTLD), or create our own alternative DNS root directory to manage the assignment of non-standard secure domain names.  We have not yet begun discussions with ICANN and we cannot assure you that we will be successful in obtaining ICANN accreditation for our registry service on terms acceptable to us or at all.  Whether or not we obtain accreditation from ICANN, we will be subject to the ongoing risks arising out of the delegation of the U.S. government’s responsibilities for the domain name system to the U.S. Department of Commerce and ICANN and the evolving government regulatory environment with respect to domain name registry services.

Employees

As of December 31, 2012, we had 14 full-time employees.

Corporate Overview and History

VirnetX, Inc., was incorporated in the State of Delaware in August 2005.  In November 2006, VirnetX acquired certain patents from SAIC.  In July 2007, we effected a reverse merger between PASW, Inc. and VirnetX, which became our principal operating subsidiary.  As a result of this merger, the former security holders of VirnetX came to own a majority of our outstanding common stock.  On October 29, 2007, we changed our name from PASW, Inc. to VirnetX Holding Corporation.

Item 1A.  Risk Factors.

We face a variety of risks that may affect our business, financial condition, operating results, the trading price of our common stock, or any combination thereof. You should carefully consider the following information and the other information in this Form 10-K in evaluating our business and prospects and before making an investment decision with respect to our common stock. If any of these risks were to occur, our business, financial condition, results of operations or prospects could be materially and adversely affected. In such an event, the market price of our common stock could decline, and you could lose all or part of your investment. The risks and uncertainties we describe below are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also affect our business.

We may not be able to capitalize on market opportunities related to our licensing strategy or our patent portfolio.

Our business strategy includes licensing our patents and technology to other companies in order to reach a larger end-user base than we could reach through direct sales and marketing efforts; as such our business strategy and revenues will depend on intellectual property licensing fees and royalties for the majority of our revenues.  We currently derive nominal revenue from licensing activities and we cannot assure you that we will successfully capitalize on our market opportunities or that our current business strategy will succeed.  Factors that may affect our ability to execute our current business strategy including, but are not limited to:

· Although we have to date entered into a limited number of settlement and license agreements, we may not be successful in entering into further licensing relationships and existing settlement and license agreements may not generate the financial results we expect;

· Third parties may challenge the validity of our patents;

· The pendency of our various litigations may cause potential licensees not to do business with us;

· We expect that we will face intense competition new and established competitors who may have superior products and services or better marketing, financial or other capacities than we do; and

· It is possible that one or more of our potential customers or licensees develops or otherwise sources products or technologies similar to, competitive with or superior to ours.

If we are not able to adequately protect our patent rights, our business would be negatively impacted.

We believe our patents are valid, enforceable and valuable.  Notwithstanding this belief, third parties may make claims of infringement or invalidity claims with respect to our patents and such claims could give rise to material cost for defense or settlement or both, jeopardize or substantially delay a successful outcome of litigation we are or may become involved in, divert resources away from our other activities, or otherwise materially and adversely affect our business.  Similar challenges could also prevent us from obtaining additional patents in the future.  Even if we are successful in enforcing our rights, our patents may not ultimately provide us with any competitive advantages and may be less valuable than we currently expect.  These risks may be heightened in countries other than the United States, and may be negatively affected by the fact that legal standards in the United States and elsewhere for protection of intellectual property rights in Internet-related businesses are uncertain and still evolving.  In addition, there are a significant number of United States and foreign patents and patent applications in our areas of interest, and we expect that significant litigation in these areas will continue, and will add uncertainty to the value of certain patents and other intellectual property rights in our areas of interest.  If we are unable to protect our intellectual property rights or otherwise realize value from them, our business would be negatively affected.

Our litigation can be time-consuming, costly and we cannot anticipate the results.

We spend a significant amount of our financial and management resources to pursue our current litigation matters.  We believe that these litigation matters and others that we may in the future determine to pursue could continue for years and continue to consume significant financial and management resources.  The counterparties to our litigation are all large, well-financed companies with substantially greater resources than us.  We cannot assure you that any of our current or future litigation matters will result in a favorable outcome for us.  In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the dispute.  Also, we cannot assure you that we will not be exposed to claims or sanctions against us which may be costly or impossible for us to defend.  Unfavorable or adverse outcomes may result in losses, exhaustion of financial resources or other adverse effects which could encumber our ability to develop and commercialize products.

We can provide no assurances that the licensing of our essential security patents under FRAND will be successful.

At the request of the European Telecommunications Standards Institute (ETSI), and the Alliance for Telecommunications Industry Solutions (ATIS), we agreed to update our licensing declaration to ETSI and ATIS under their respective Intellectual Property Rights (IPR) policies.  This was in response to our Statement of Patent Holder identifying a group of our patents and patent applications that we believe are or may become essential to certain developing specifications in the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), Systems Architecture Evolution (SAE) project.  We will make available a non-exclusive patent license under FRAND (fair, reasonable and non-discriminatory terms and conditions, with compensation) for the patents identified by VirnetX that are or become essential, to applicants desiring to implement the Technical Specifications identified by VirnetX, as set forth in the updated licensing declaration under the ATIS and ETSI IPR policies. While we believe that our FRAND commitment positions us to license our essential security patents for the Technical Specifications identified by VirnetX, our licensing declarations under the ATIS and ETSI IPR policies may limit our flexibility in determining royalties and license terms for certain of our patents.  Consequently, we cannot assure you that the licensing of the essential security patents will be successful or that third parties will be willing to enter into licenses with VirnetX on reasonable terms or at all, which could have an adverse effect on our business and harm our competitive position.

Because our business is conducted or expected to be conducted in an environment that is subject to rapid change, we may be subjected to various developments in regulation, law and consumer preferences to which we may not be able to adapt successfully.

The current regulatory environment for our products and services remains unclear.  We can give no assurance that our planned product offerings will be in compliance with laws and regulations of local, state, United States federal or foreign authorities.  Further, we can give no assurance that we will not unintentionally violate such laws or regulations or that such laws or regulations will not be modified, or that new laws or regulations will be enacted in the future which would cause us to be in violation of such laws or regulations.  For example, Voice-over-Internet Protocol (or VoIP) services are not currently subject to all of the same regulations that apply to traditional telephony, but it is possible that similar regulations may be applied to VoIP in the future and that these could result in substantial costs and adversely effect the marketability of our products and planned products related to VoIP.  For further example, the use of the Internet and private Internet Protocol (IP) networks for communication is largely unregulated within the United States, but may become regulated in the future; also several foreign governments have enacted measures that could restrict or prohibit voice communications services over the Internet or private IP networks.

11

Our business depends on the growth of instant messaging, VoIP, mobile services, streaming video, file transfer and remote desktop and other next-generation Internet-based applications which are relatively new.  A decline in the use of these applications due to complexity or cost of these applications relative to alternate traditional or newly developed communications channels, or development of alternative technologies, could cause a material decline in the number of users in these areas.

More aggressive domestic or international regulation of the Internet in general, and Internet telephony providers and services specifically, or a lack of growth in acceptance of the Internet as a long term viable marketplace for communications services, may materially and adversely affect our business, financial condition, operating results and future prospects.

Our exposure to outside influences beyond our control, including new legislation, court rulings or actions by the United States Patent and Trademark Office, could adversely affect our licensing and enforcement activities and results of operations.

Our licensing and enforcement activities are subject to numerous risks from outside influences, including the following:

• New legislation, regulations or rules related to obtaining patents or enforcing patents could significantly increase our operating costs and decrease our revenue. For instance, the U.S. Supreme Court has recently modified some tests used by the United States Patent and Trademark Office (USPTO) in granting patents during the past 20 years which may decrease the likelihood that we will be able to obtain patents and increase the likelihood of challenge of any patents we obtain or license.  In addition, the U.S. recently enacted sweeping changes to the United States patent system under the Leahy-Smith America Invents Act (“AIA”), including changes that transition the United States from a “first-to-invent” system to a “first to file” system and alter the processes for challenging issued patents

• More patent applications are filed each year resulting in longer delays in getting patents issued by the USPTO.

• Federal courts are becoming more crowded, and as a result, patent enforcement litigation is taking longer.

If we experience security breaches, we could be exposed to liability and our reputation and business could suffer.

We expect to retain certain confidential customer information in our secure data centers and secure domain name registry.  It will be critical to our business strategy that our facilities and infrastructure remain secure and are perceived by the marketplace to be secure.  Our secure domain name registry operations will also depend on our ability to maintain our computer and telecommunications equipment in effective working order and to reasonably protect our systems against interruption, and potentially depend on protection by other registrars in the shared registration system.  The secure domain name servers that we will operate will be critical hardware to our registry services operations.  Therefore, we expect to have to expend significant time and money to maintain or increase the security of our facilities and infrastructure.  Security technologies are constantly being tested by computer professionals, academics and “hackers.” Advances in the techniques for attacking security solutions could make some or all of our products obsolete or unmarketable.  Likewise, if any of our products are found to have significant security vulnerabilities, then we may need to dedicate engineering and other resources to eliminate the vulnerabilities and to repair or replace products already sold or licensed to our customers.  Despite our security measures, our infrastructure may be vulnerable to physical break-ins, computer viruses, attacks by hackers or similar disruptive problems.  It is possible that we may have to expend additional financial and other resources to address such problems.  Any physical or electronic break-in or other security breach or compromise of the information stored at our secure data centers and domain name registration systems may jeopardize the security of information stored on our premises or in the computer systems and networks of our customers.  In such an event, we could face significant liability and customers could be reluctant to use our services.  Such an occurrence could also result in adverse publicity and therefore adversely affect the market’s perception of the security of electronic commerce and communications over IP networks as well as the security or reliability of our services.

A security breach could require a substantial amount of expense to rectify and could result in a product liability claim that causes us to incur substantial liability and related legal and other costs.  A security breach may also harm our reputation and make it more difficult or impossible for us to successfully market to others.  These matters could harm our operating results and financial condition.

We expect that we will experience long and unpredictable sales cycles, which may impact our operating results.

We expect that our sales cycles will be long and unpredictable due to a number of uncertainties such as:

· The need to educate potential customers about our patent rights and our product and service capabilities;

· Customers’ willingness to invest potentially substantial resources and modify their network infrastructures to take advantage of our products;

· Customers’ budgetary constraints;

· The timing of customers’ budget cycles; and

· Delays caused by customers’ internal review processes.

Long sales cycles may increase the risk that our financial resources are exhausted before we are able to generate significant revenue.

We expect that we will be substantially dependent on a concentrated number of customers.  If we are unable to establish, maintain or replace our relationships with customers and develop a diversified customer base, our revenues may fluctuate and our growth may be limited.

We expect that in the future, a significant portion of our revenues will be generated from a limited number of customers.  Substantially all of our income during 2010 was from the payments to us resulting from the Settlement and License Agreement we entered into with Microsoft. Nominal revenues from 2010 and 2011 were derived from a single licensing agreement and 2012 revenues were derived from 3 settlement and license agreements entered into as we settled lawsuits we initiated against customers for patent infringements. There can be no guarantee that we will be able to obtain additional customers, or if we do so, to sustain our revenue levels from these prospective customers.  If we are not able to establish, maintain or replace the limited group of prospective customers that we anticipate may generate a substantial majority of our revenues in the future, or if they do not generate revenues at the levels or at the times that we anticipate, our ability to maintain or grow our revenues will be adversely affected.

12

Our products are highly technical and may contain undetected errors, which could cause harm to our reputation and adversely affect our business.

Our products are highly technical and complex and, when deployed, may contain errors or defects.  Despite testing, some errors in our products may only be discovered after a product has been installed and used by customers.  Any errors or defects discovered in our products after commercial release could result in failure to achieve market acceptance, loss of revenue or delay in revenue recognition, loss of customers and increased service and warranty cost, any of which could adversely affect our business, operating results and financial condition.  In addition, we could face claims for product liability, tort or breach of warranty, including claims relating to changes to our products made by our channel partners.  The performance of our products could have unforeseen or unknown adverse effects on the networks over which they are delivered as well as on third-party applications and services that utilize our services, which could result in legal claims against us, harming our business.  Furthermore, we expect to provide implementation, consulting and other technical services in connection with the implementation and ongoing maintenance of our products, which typically involves working with sophisticated software, computing and communications systems.  We expect that our contracts with customers will contain provisions relating to warranty disclaimers and liability limitations, which may not be upheld.  Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention and adversely affect the market’s perception of us and our products.  In addition, if our business liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business, operating results and financial condition could be adversely impacted.

Malfunctions of third-party communications infrastructure, hardware and software expose us to a variety of risks we cannot control.

Our business will also depend upon the capacity, reliability and security of the infrastructure owned by third parties that we will use to deploy our offerings.  We have no control over the operation, quality or maintenance of a significant portion of that infrastructure or whether or not those third parties will upgrade or improve their equipment.  We depend on these companies to maintain the operational integrity of our connections.  If one or more of these companies is unable or unwilling to supply or expand its levels of service to us in the future, our operations could be severely interrupted.  Also, to the extent the number of users of networks utilizing our future products suddenly increases, the technology platform and secure hosting services which will be required to accommodate a higher volume of traffic may result in slower response times or service interruptions.  System interruptions or increases in response time could result in a loss of potential or existing users and, if sustained or repeated, could reduce the appeal of the networks to users.  In addition, users depend on real-time communications; outages caused by increased traffic could result in delays and system failures.  These types of occurrences could cause users to perceive that our solution does not function properly and could therefore adversely affect our ability to attract and retain licensees, strategic partners and customers.

System failure or interruption or our failure to meet increasing demands on our systems could harm our business.

The success of our license and service offerings will depend on the uninterrupted operation of various systems, secure data centers and other computer and communication networks that we establish.  To the extent the number of users of networks utilizing our future products suddenly increases, the technology platform and hosting services which will be required to accommodate a higher volume of traffic may result in slower response times, service interruptions or delays or system failures.  Our systems and operations will also be vulnerable to damage or interruption from:

· power loss, transmission cable cuts and other telecommunications failures;

· damage or interruption caused by fire, earthquake, and other natural disasters

· computer viruses or software defects; and

· physical or electronic break-ins, sabotage, intentional acts of vandalism, terrorist attacks and other events beyond our control.

System interruptions or failures and increases or delays in response time could result in a loss of potential or existing users and, if sustained or repeated, could reduce the appeal of the networks to users.  These types of occurrences could cause users to perceive that our solution does not function properly and could therefore adversely affect our ability to attract and retain licensees, strategic partners and customers.

Any significant problem with our systems or operations could result in lost revenue, customer dissatisfaction or lawsuits against us.  A failure in the operation of our secure domain name registration system could result in the inability of one or more registrars to register and maintain secure domain names for a period of time.  A failure in the operation or update of the master directory that we plan to maintain could result in deletion or discontinuation of assigned secure domain names for a period of time.  The inability of the registrar systems we establish, including our back office billing and collections infrastructure, and telecommunications systems to meet the demands of an increasing number of secure domain name requests could result in substantial degradation in our customer support service and our ability to process registration requests in a timely manner.

Our ability to sell our solutions will be dependent on the quality of our technical support, and our failure to deliver high-quality technical support services could have a material adverse effect on our sales and results of operations.

If we do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues and provide effective ongoing support, or if potential customers perceive that we may not be able achieve to the foregoing, our ability to sell our products would be adversely affected, and our reputation with potential customers could be harmed.  In addition, as we expand our operations internationally, our technical support team will face additional challenges, including those associated with delivering support, training and documentation in languages other than English.  Our failure to deliver and maintain high-quality technical support services to our customers could result in customers choosing to use our competitors’ products instead of ours in the future.

Telephone carriers have petitioned governmental agencies to enforce regulatory tariffs, which, if granted, would increase the cost of online communication, and such increase in cost may impede the growth of online communication and adversely affect our business.

Use of the Internet has over-burdened existing telecommunications infrastructures, and many high traffic areas have begun to experience interruptions in service.  As a result, certain local telephone carriers have petitioned governmental agencies to enforce regulatory tariffs on IP telephony traffic that crosses over their traditional telephone networks.  If the relief sought in these petitions is granted, the costs of communicating via online could increase substantially, potentially adversely affecting the growth in the use of online secure communications.  Any of these developments could have an adverse effect on our business.

13

The departure of Kendall Larsen, our Chief Executive Officer and President, and/or other key personnel could compromise our ability to execute our strategic plan and may result in additional severance costs to us.

Our success largely depends on the skills, experience and efforts of our key personnel, including Kendall Larsen, our Chief Executive Officer and President.  We have no employment agreements with any of our key executives that prevent them from leaving us at any time.  In addition, we do not maintain key person life insurance for any of our officers or key employees.  The loss of Mr. Larsen, or our failure to retain other key personnel, would jeopardize our ability to execute our strategic plan and materially harm our business.

We will need to recruit and retain additional qualified personnel to successfully grow our business.

Our future success will depend in part on our ability to attract and retain qualified operations, marketing and sales personnel as well as engineers.  Inability to attract and retain such personnel could adversely affect our business.  Competition for engineering, sales, marketing and executive personnel is intense, particularly in the technology and Internet sectors and in the region in which our facility is located.  We can provide no assurance that we will attract or retain such personnel.

Our consolidated financial statements were restated in 2011 in connection with our identification of a material weakness in our internal control over financial reporting; we may identify future material weakness which may result in late filings, increased costs or declines in our share price.

In early 2011, we restated our previously filed financial statements for the fiscal quarter ended September 30, 2010, each of the then previous five fiscal quarters and the fiscal year ended December 31, 2009, to adjust our accounting for our Series I Warrants.  In connection with these restatements, we determined that we had not maintained effective control over our accounting for these Series I Warrants and, as a result, that a material weakness existed with respect to our reporting of complex, non-routine transactions as of the end of the periods covered by the Form 10-K and Form 10-Qs that included the financial statements referenced above. Although we believe that we currently maintain effective control over our disclosure controls and procedures and internal control over financial reporting as regards this issue, we may in the future identify deficiencies regarding the design and effectiveness of our system of internal control over financial reporting.   If we experience any material weaknesses in our internal control over financial reporting the future or are unable to provide unqualified management or attestation reports about our internal controls, we may be unable to meet financial and other reporting deadlines and may incur costs associated with remediation, and any of which could cause our share price to decline.

We do not currently pay dividends on our common stock and thus stockholders must look to appreciation of our common stock to realize a gain on their investments.

Although we paid a special cash dividend to holders of our common stock with a record date of July 1, 2010, we do not currently pay regular dividends on our common stock and instead retain future earnings to fund our business plan.  Our future dividend policy is within the discretion of our Board of Directors and will depend upon various factors, including our business, financial condition, results of operations, capital requirements, and investment opportunities.  We therefore can’t assure you that our Board of Directors will determine to pay regular or special dividends in the future. Accordingly, unless our Board of Directors determines to pay dividends, stockholders will be required to look to appreciation of our common stock to realize a gain on their investment.  This appreciation may not occur.

The exercise of our outstanding stock options would result in a dilution of our current stockholders' voting power and an increase in the number of shares eligible for future resale in the public market which may negatively impact the market price of our stock.

The exercise of our outstanding vested stock options would dilute the ownership interests of our existing stockholders. As of December 31, 2012, we had outstanding options and restricted stock units to purchase an aggregate of 4,927,889 shares of common stock (representing 9.57% of our total shares outstanding as of December 31, 2012) of which 4,033,124 are vested and therefore exercisable. To the extent outstanding stock options are exercised, additional shares of common stock will be issued, and such issuance would dilute non-exercising stockholders' percentage voting interests and increase the number of shares eligible for resale in the public market.

The fair value of accounting for our Series I Warrants as derivative liabilities may materially impact our results of our operations in future periods.

We record the Series I Warrants as a derivative liability in accordance with ASC 815-40, “Derivatives and Hedging – Contracts in Entity’s Own Equity.”  These derivative liabilities are reported at fair value each reporting period with changes in the fair value recognized as gain or loss during each reporting period.  An increase in our share price or measure of our share price volatility, for example, will generally result in an increase in the fair value of our warrant liability and a non-cash charge during the period of such increase, which could materially and negatively impact our results of operations in future periods.

Trading in our common shares is limited and the price of our common shares may be subject to substantial volatility, particularly in light of the instability in the financial and capital markets.

Our common stock is listed on NYSE Amex, but its daily trading volume has been limited, sporadic and volatile.  Over the past years the market price of our common stock has experienced significant fluctuations.  Between January 1, 2012, and December 31, 2012, the reported last sale price for our common stock ranged between $20.27 and $40.47 per share.  The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but not limited to, the following:

● developments in any then-outstanding litigation;

● quarterly variations in our operating results;

● large purchases or sales of common stock or derivatives transactions related to our stock;

● actual or anticipated announcements of new products or services by us or competitors;

● general conditions in the markets in which we compete; and

● economic and financial conditions.

14

The market price of our common stock may decline because our operating results may not be consistent and may be difficult to predict.

Our reported net income has fluctuated in the past due to several factors. We expect that our future operating results may also fluctuate due to the same or similar factors.  We had net income of $41.4 million for the year ended December 31, 2010, a net loss of $17.3 million for the year ended December 31, 2011, and a net loss $26.9 million for the year ended December 31, 2012 with an accumulated deficit of $62.9 million. The following include some of the factors that may cause our operating results to fluctuate:

· the outcome of actions to enforce our intellectual property rights currently in progress or that we may undertake in the future, and the timing thereof;

· the amount and timing of receipt of license fees from potential infringers, licensees or customers;

· the rate of adoption of our patented technologies;

· the number of new license arrangements we may execute, or that may expire, within a particular period and the scope of those licenses, including the number of our patents which are licensed, the extent of prior infringement of our patent rights, royalty rates, timing of payment obligations, expiration date etc;

· the success of a licensee in selling products that use our patented technologies; and

· the amount and timing of expenses related to our patent filings and enforcement proceedings, including litigation, related to our intellectual property rights.

These fluctuations may make our business particularly difficult to manage, adversely affect our business and operating results, make our operating results difficult for investors to predict and, further, cause our results to fall below investor’s expectations and adversely affect the market price of our common stock.

Because ownership of our common stock is concentrated, investors may have limited influence on stockholder decisions.

As of December 31, 2012, our executive officers and directors beneficially owned approximately 20% of our then outstanding common stock.  In addition, a group of stockholders that, as of December 31, 2007, held 4,766,666 shares, or approximately 12%, of our then outstanding common stock, have entered into a voting agreement with us that requires them to vote all of their shares of our voting stock in favor of the director nominees approved by our Board of Directors at each director election going forward, and in a manner that is proportional to the votes cast by all other voting shares as to any other matters submitted to the stockholders for a vote.  However, we cannot be certain how many shares of our common stock this group of stockholders currently owns.  Because of their beneficial ownership interest, our officers and directors could significantly influence stockholder actions of which you disapprove or that are contrary to your interests.  This ability to exercise significant influence could prevent or significantly delay another company from acquiring or merging with us.

Our protective provisions could make it difficult for a third party to successfully acquire us even if you would like to sell your stock to them.

We have a number of protective provisions that could delay, discourage or prevent a third party from acquiring control of us without the approval of our Board of Directors.  Our protective provisions include:

● A staggered Board of Directors: This means that only one or two directors (since we have a five-person Board of Directors) will be up for election at any given annual meeting.  This has the effect of delaying the ability of stockholders to effect a change in control of us because it would take two annual meetings to effectively replace a majority of the Board of Directors.

● Blank check preferred stock: Our Board of Directors has the authority to establish the rights, preferences and privileges of our 10,000,000 authorized, but unissued, shares of preferred stock.  Therefore, this stock may be issued at the discretion of our Board of Directors with preferences over your shares of our common stock in a manner that is materially dilutive to you.  In addition, blank check preferred stock can be used to create a “poison pill” which is designed to deter a hostile bidder from buying a controlling interest in our stock without the approval of our Board of Directors.  We have not adopted such a “poison pill;” but our Board of Directors has the ability to do so in the future, very rapidly and without stockholder approval.

● Advance notice requirements for director nominations and for new business to be brought up at stockholder meetings: Stockholders wishing to submit director nominations or raise matters to a vote of the stockholders must provide notice to us within very specific date windows and in very specific form in order to have the matter voted on at a stockholder meeting.  This has the effect of giving our Board of Directors and management more time to react to stockholder proposals generally and could also have the effect of disregarding a stockholder proposal or deferring it to a subsequent meeting to the extent such proposal is not raised properly.

● No stockholder actions by written consent: No stockholder or group of stockholders may take actions rapidly and without prior notice to our Board of Directors and management or to the minority stockholders.  Along with the advance notice requirements described above, this provision also gives our Board of Directors and management more time to react to proposed stockholder actions.

● Super majority requirement for stockholder amendments to the By-laws: Stockholder proposals to alter or amend our By-laws or to adopt new By-laws can only be approved by the affirmative vote of at least 66 2/3% of the outstanding shares of our common stock.

● No ability of stockholders to call a special meeting of the stockholders: Only the Board of Directors or management can call special meetings of the stockholders.  This could mean that stockholders, even those who represent a significant percentage of our shares of common stock, may need to wait for the annual meeting before nominating directors or raising other business proposals to be voted on by the stockholders.

15

In addition, the provisions of Section 203 of the Delaware General Corporate Law govern us.  These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

These and other provisions in our amended and restated certificate of incorporation, our By-laws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.

Item 2.  Properties.

Our principal executive offices are located at 308 Dorla Court, Suite 206, Zephyr Cove, Nevada 89448.  We lease this property, which comprises approximately 2,090 square feet of office space, from a third party for a term that ends in 2013.  We have no other properties and believe that our office facility is suitable and appropriately supports our current business needs. Until October 2011, our principal executive offices were located at 5615 Scotts Valley Drive, Suite 110, Scotts Valley, California 95066, which we leased for a term that was scheduled to end in 2012.  In connection with the move of our corporate offices to Nevada, we terminated the Scotts Valley lease effective October 2011.

Item 3.  Legal Proceedings.

We have four intellectual property infringement lawsuits pending against multiple parties in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief in all the complaints. We have one complaint with the United States International Trade Commission (ITC) alleging that Apple, Inc. has engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain devices with secure communication capabilities that infringe one or more claims of our U.S. Patent No. 8,051,181. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.’s infringement through the district courts.

VirnetX Inc. v. Cisco Systems, Inc. et al

On August 11, 2010, we initiated a lawsuit by filing a complaint against Aastra, Apple, Cisco, and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief. On February 4, 2011, we amended our original complaint, filed on August 11, 2010, against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to assert U.S. Patent No. 7,418,504 against Apple and Aastra. On April 5, 2011, we again amended our complaint against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to include Apple’s iPad 2 in the list of Apple products that are accused of infringing our patents. We also asserted our newly-issued patent, U.S. Patent No. 7,921,211 against all of the defendants in that lawsuit. A claim construction hearing was held on January 5, 2012 and the court issued a Markman ruling on April 25, 2012. Aastra and NEC have signed license agreements with us and we have dismissed the patent infringement cases against them. At the pre-trial hearing, the judge decided to postpone the trial against Cisco to March 4, 2013 and just try the case against Apple. On November 6, 2012, a Jury in the United States Court for the Eastern District of Texas, Tyler Division, awarded us over $368,000,000 in a verdict against Apple Corporation for infringing four of our patents. A post-trial hearing in the case against Apple was held on December 20, 2012. On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the prior jury verdict. The Court denied Apple’s motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple’s request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. Specifically, the Court ordered that Apple pay $33,561 in daily interest up to final judgment and $330,201 in daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. In doing so, the Court ordered the parties to mediate over a license in the following 45 days for Apple’s future infringing use not covered by the Court’s Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court. The preparations for the jury trial against Cisco on March 4, 2013 are underway.

VirnetX Inc. v. Mitel Networks Corporation et al

On January 12, 2011, we initiated a lawsuit by filing a complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these companies infringe three of our patents.  We seek damages and injunctive relief. On April 12, 2011 we again amended our complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, to add Avaya Inc. as a defendant. On July 11, 2012, Mitel Network Corporation signed a license agreement with us and we dismissed the patent infringement case against them. On July 12, 2012 we had a claims construction hearing in this case and a markman order was issued on August 1, 2012. On January 29, 2013 Siemens signed a license agreement with us and we dismissed the patent infringement case against them. The preparations for the jury trial against Avaya on March 4, 2013 are underway.

VirnetX Inc. v. Apple, Inc

On November 1, 2011, we initiated a lawsuit against Apple in the United States District Court, Tyler Division, pursuant to which we allege that Apple infringes one or more claims of our U.S. Patent No. 8,051,181.  We seek damages and injunctive relief.  No hearing or trial dates have been set.

VirnetX Inc. v. Apple, Inc.

On November 6, 2012, we filed a new complaint against Apple Inc., in the United States District Court for the Eastern District of Texas, Tyler Division for willfully infringing four of our patents, U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151, and seeking both damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Due to their release dates, these products were not included in the previous lawsuit that concluded with a Jury verdict on November 6, 2012 that was subsequently upheld by the United States District Court for the Eastern District of Texas, Tyler Division, on February 26, 2013.

ITC Investigation No. 337-TA-858

On July 18, 2012, the Administrative Law Judge (ALJ) assigned to investigate our complaint against Apple Inc., identified a procedural discrepancy with our complaint and dismissed it. On September 14, 2012, we re-filed our complaint with the ITC jointly with Science Applications International Corporation (SAIC) [NYSE: SAI] to remove a procedural standing issue that was identified as the reason for dismissal of our previous complaint. On October 16, 2012, the United States International Trade Commission (ITC) accepted our complaint and instituted an investigation against Apple and assigned ALJ E. James Gildea to preside over this investigation. Subsequently on October 23, 2012, ALJ Gildea issued an order setting up February 21, 2014 as the target date for completion of this investigation. The hearing in-front of ALJ Gildea is scheduled for May 20, 2013. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.’s infringement through the district courts.

One or more potential intellectual property infringement claims may also be available to us against certain other companies who have the resources to defend against any such claims.  Although we believe these potential claims are worth pursuing, commencing a lawsuit can be expensive and time-consuming, and there is no assurance that we will prevail on such potential claims.  In addition, bringing a lawsuit may lead to potential counterclaims which may preclude our ability to commercialize our initial products, which are currently in development.

Currently, we are not a party to any other pending legal proceedings, and are not aware of any proceeding threatened or contemplated against us by any governmental authority or other party.

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

Company Overview

We develop software and technology solutions for securing real-time communications over the Internet.  Our patented GABRIEL Connection Technology™ combines industry standard encryption protocols with our patented techniques for automated domain name system, or DNS, lookup mechanisms, and enables users to create a secure communication link using secure domain names over wired or wireless (4G/LTE) networks. We are currently beta testing our GABRIEL Connection Technology™ as part of our Secure Domain Name Initiative, or (SDNI), on various platforms including PCs, smart phones and tablets. We also intend to establish the exclusive secure domain name registry in the United States and other key markets around the world.

Our portfolio of intellectual property is the foundation of our business model.  We currently own 20 patents in the United States and 32 foreign patents, as well as several pending U.S. and foreign patent applications.  Our patent portfolio is primarily focused on securing real-time communications over the Internet, as well as related services such as the establishment and maintenance of a secure domain name registry.  Our patented methods also have additional applications in operating systems and network security.  We have submitted  a declaration with the 3rd Generation Partnership Project, or 3GPP, identifying a group of our patents and patent applications that we believe are or may become essential to certain developing specifications in the 3GPP LTE, SAE project. We have agreed to make available a non-exclusive patent license under fair, reasonable and non-discriminatory terms and conditions, with compensation, or FRAND, to 3GPP members desiring to implement the technical specifications identified by us. We believe that we are positioned to license our essential security patents to 3GPP members as they move into 4G.

We intend to seek further license of our technology, including our GABRIEL Connection Technology™ to enterprise customers, developers and original equipment manufacturers, or OEMs, of chips, servers, smart phones, tablets, e-Readers, laptops, net books and other devices, within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets including 4G/LTE. We have published our royalty rates and guidelines on our website. All forward moving licenses have adhered to these guidelines and have met or exceeded these rates and we will use these rates and guidelines in all future license negotiations. We believe that the market opportunity for our software and technology solutions is large and expanding as secure domain names are now an integral part of securing the next generation 4G/LTE wireless networks. We also believe that all 4G mobile devices will require unique secure domain names and become part of a secure domain name registry.

Our software and technology solutions provide the security platform required by next-generation Internet-based applications such as instant messaging, or IM, voice over Internet protocol, or VoIP, mobile services, streaming video, file transfer and remote desktop.  Our technology generates secure connections on a “zero-click” or “single-click” basis, significantly simplifying the deployment of secure real-time communication solutions by eliminating the need for end-users to enter any encryption information.

In connection with the settlement of our lawsuit against Microsoft Corporation in 2010, Microsoft became our first licensee.  Pursuant to the Settlement and License Agreement between us and Microsoft, Microsoft paid us $200 million, which has been recognized as gain on settlement and Microsoft was granted a worldwide, irrevocable, nonexclusive, non-sub licensable fully paid up license for our patents for Microsoft products. We have also signed Patent License Agreements with Aastra USA, Inc. Mitel Networks Corporation, NEC Corporation and NEC Corporation of America, Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc. to license certain of our US patents, for a one-time payment and an ongoing royalty for all future sales through the expiration of the licensed patents with respect to certain current and future IP-encrypted products.

Our employees include the core development team behind our patent portfolio, technology and software.  This team has worked together for over ten years and is the same team that invented and developed this technology while working at Science Application International Corporation, or SAIC.  SAIC is a FORTUNE 500® scientific, engineering and technology applications company that uses its deep domain knowledge to solve problems of vital importance to the nation and the world, in national security, energy and the environment, critical infrastructure and health. The team has continued its research and development work started at SAIC and expanded the set of patents we acquired in 2006 from SAIC into a larger portfolio with 52 issued U.S. and foreign patents and numerous pending U.S. and foreign patent applications. This portfolio now serves as the foundation of our licensing business and planned service offerings and is expected to generate the majority of our future revenue in license fees and royalties. We intend to continue our research and development efforts to further strengthen and expand our patent portfolio.  Please see Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Operations – Research and Development Expenses for a description of our research and development expenses for the past three fiscal years.

We intend to continue using an outsourced and leveraged model to maintain efficiency and manage costs as we grow our licensing business by offering incentives to early licensing targets or asserting our rights for use of our patents.  We also intend to expand our design pilot in participation with leading 4G/LTE companies (domain infrastructure providers, chipset manufacturers, service providers, and others) and build our secure domain name registry.

Developments in the Year Ended December 31, 2012

Litigation

We have four intellectual property infringement lawsuits pending against multiple parties in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief in all the complaints. We have one complaint with the United States International Trade Commission (ITC) alleging that Apple, Inc. has engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain devices with secure communication capabilities that infringe one or more claims of our U.S. Patent No. 8,051,181.

On January 5, 2012, a claim construction hearing was held in our case against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division. On April 25, 2012 the United States District Court for the Eastern District of Texas, Tyler Division, issued its Markman Order on the claim terms that were in dispute in the  Aastra, Apple, Cisco and NEC litigation and adopted certain interpretations that we believe are favorable to us.

On May 3, 2012, we entered into a License Agreement with Aastra USA, Inc. Under the terms of the Agreement, the parties agreed to dismiss the patent infringement case between the parties and their affiliates before the U.S. District Court for the Eastern District of Texas.

On July 11, 2012, we entered into a License Agreement with Mitel Network Corporation. Under the terms of the Agreement, the parties agreed to dismiss the patent infringement case between the parties and their affiliates before the U.S. District Court for the Eastern District of Texas.

On July 12, 2012, a claims construction hearing was held in our complaint against Siemens Enterprise Communications and Avaya Inc. in the United States District Court for the Eastern District of Texas, Tyler Division. On August 1, 2012 the United States District Court for the Eastern District of Texas, Tyler Division, issued its Markman Order denying the request by the defendants to change the interpretation of some of the claim terms that were in dispute in the litigation, leaving them unchanged from what was previously adopted by the court in the Markman ruling in its other ongoing infringement action against Cisco, Apple and NEC. At that time jury selection for the trial in connection with the Siemens and Avaya litigation was scheduled to start on November 5, 2012.

On July 18, 2012, the Administrative Law Judge assigned to investigate our complaint with the United States International Trade Commission (ITC) against Apple Inc., identified a procedural discrepancy with the complaint that would impact the scheduling of the investigation. We disagreed with this finding and on July 26, 2012 filed an appeal with the ITC in this regard. This appeal was denied on August 20, 2012.

On August 2, 2012, we entered into a License Agreement with NEC Corporation and NEC Corporation of America. Under the terms of the Agreement, the parties agreed to dismiss the patent infringement case between the Parties and their affiliates before the U.S. District Court for the Eastern District of Texas.

On September 14, 2012, we re-filed our complaint with the United States International Trade Commission (ITC) alleging that Apple Inc. has engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain devices with secure communication capabilities that infringe one or more claims of VirnetX’s U.S. Patent No. 8,051,181 (“the ‘181 patent”).  The accused products include the latest iPhones, iPads, iPods, and Macintosh computers. The complaint was filed jointly with Science Applications International Corporation (SAIC) [NYSE: SAI] to remove a procedural standing issue that was identified as the reason for dismissal of our previous complaint.

On September 18, 2012, we announced that after a hearing at the United States District Court for the Eastern District of Texas, Tyler Division, requested by all the parties, the judge agreed to modify the trial schedule in our patent infringement suits against Apple, Cisco, Avaya and Siemens to allow for optimum use of resources for trial preparation while giving parties additional time to try to reach an agreement. Per the updated schedule, jury selection in our complaint against Apple was to begin on October 29, 2012 followed by a jury trial on October 31, 2012. Remaining defendants including Cisco, Avaya and Siemens are now scheduled for a jury selection on March 4, 2013.

On October 16, 2012, the United States International Trade Commission (ITC) accepted our complaint and instituted an investigation against Apple and assigned Administrative Law Judge (ALJ) E. James Gildea to preside over this investigation. Subsequently on October 23, 2012, the ALJ issued an order setting February 21, 2014 as the Target date for completion of this investigation. The hearing in-front of the ALJ is scheduled for May 20, 2013.

On November 6, 2012, a jury in the United States Court for the Eastern District of Texas, Tyler Division, awarded us over $368,000,000 in a verdict against Apple Corporation for infringing four of our patents.

On November 6, 2012, we filed a new complaint against Apple Inc., in the United States District Court for the Eastern District of Texas, Tyler Division for willfully infringing four of our patents, U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151, and seeking both damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Due to their release dates, these products were not included in the previous lawsuit that resulted in a jury verdict on November 6, 2012.

On December 20, 2012, a post-trial motion hearing was held in the United States District Court for the Eastern District of Texas, Tyler Division with respect to the jury verdict against Apple Inc. During the hearing, a number of motions from both sides were heard by the judge. At the hearing the judge ordered Apple Inc., to provide updated sales data for certain accused and non-accused products, including the iPhone 5 by January 15, 2013. This data was submitted on January 15, 2013. On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the prior jury verdict. The Court denied Apple’s motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple’s request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. Specifically, the Court ordered that Apple pay $33,561 in daily interest up to final judgment and $330,201 in daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. In doing so, the Court ordered the parties to mediate over a license in the following 45 days for Apple’s future infringing use not covered by the Court’s Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court.

Patents

On August 10, 2012, we submitted updates to our licensing declaration to European Telecommunications Standards Institute (ETSI) and the Alliance for Telecommunications Industry Solutions (ATIS) where we identified three (3) additional developing specifications in the 3GPP LTE, SAE project to which our patents and patent applications are or may become essential.

On September 18, 2012, we submitted additional updates to our licensing declaration to European Telecommunications Standards Institute (ETSI) and the Alliance for Telecommunications Industry Solutions (ATIS) where we identified seven (7) additional developing specifications in the 3GPP LTE, SAE project to which our patents and patent applications are or may become essential.

On February 28, 2012, we announced that the United States Patent and Trademark Office (“USPTO”) issued an Action Closing Prosecution for our U.S. Patent No. 7,188,180 in the inter-partes reexamination filed by Cisco Systems, Inc. on October 25, 2011, confirming all of our claims as valid and patentable. The USPTO rejected all of Cisco’s proposed validity challenges to U.S. Patent No. 7,188,180, and withdrew all of its grounds for rejection.

Commitments

On October 30, 2011, we entered into a new lease agreement with Sierra Tahoe Professional Center, LLC., for our corporate headquarters located at 308 Dorla Court, Suite 206, Zephyr Cove, Nevada 89448. The lease commencement date was October 30, 2011 and includes montly payments of $5 until the lease term expires in October 2013.

Recent Developments

On January 29, 2013, we entered into a License Agreement with Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc.. Under the terms of the Agreement, the Parties have agreed to dismiss the patent infringement case between the Parties and their affiliates before the U.S. District Court for the Eastern District of Texas.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us 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 revenues and expenses during the reported period.  The critical accounting policies we employ in the preparation of our consolidated financial statements are those which involve impairment of long-lived assets, income taxes, fair value of financial instruments and stock-based compensation.

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP"). In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below. We have reviewed our critical accounting policies and estimates with the audit committee of our board of directors.

Revenue Recognition

We derive our revenue from patent licensing. The timing and amount of revenue recognized from each licensee depends upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements can be complex and may or may not include multiple elements. These agreements may include, without limitation, elements related to the settlement of past patent infringement liabilities, up-front and non-refundable license fees for the use of patents, patent licensing royalties on covered products sold by licensees, and the compensation structure and ownership of intellectual property rights associated with contractual technology development arrangements. Beginning January 1, 2011, licensing agreements are accounted for under the Financial Accounting Standards Board ("FASB") revenue recognition guidance, "Revenue Arrangements with Multiple Deliverables." This guidance requires consideration to be allocated to each element of an agreement that has stand-alone value using the relative fair value method. In other circumstances, such as those agreements involving consideration for past and expected future patent royalty obligations, after consideration of the particular facts and circumstances, the appropriate recording of revenue between periods may require the use of judgment. In all cases, revenue is only recognized after all of the following criteria are met: (1) written agreements have been executed; (2) delivery of technology or intellectual property rights has occurred or services have been rendered; (3) fees are fixed or determinable; and (4) collectability of fees is reasonably assured.

Patent License Agreements: Upon signing a patent license agreement, we provide the licensee permission to use our patented technology in specific applications. We account for patent license agreements in accordance with the guidance for revenue arrangements with multiple deliverables and the guidance for revenue recognition. We have elected to utilize the leased-based model for revenue recognition, with revenue being recognized over the expected period of benefit to the licensee. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in specific applications and products:

Consideration for Past Sales: Consideration related to a licensee’s product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented technology prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive royalty for past sales in connection with the settlement of patent litigation where there was no prior patent license agreement. These amounts are negotiated based upon application of a royalty rate to historical sales prior to the execution of the license agreement. In each of these cases, since delivery has occurred, we record the consideration as revenue when we have obtained a signed agreement, identified a fixed or determinable price, and determined that collectability is reasonably assured.

Current Royalty Payments: These are ongoing royalty payments covering a licensee’s obligations to us related to its sales of covered products in the current contractual reporting period. Licensees that owe Current Royalty Payments are obligated to provide us with quarterly or semi-annual royalty reports that summarize their sales of covered products and their related royalty obligations to us. We expect to receive these royalty reports subsequent to the period in which our licensees’ underlying sales occurred. As a result, it is impractical for us to recognize revenue in the period in which the underlying sales occur, and, in most cases, we will recognize revenue in the period in which the royalty report is received and other revenue recognition criteria are met due to the fact that without royalty reports from our licensees, our visibility into our licensees’ sales is limited. Current Royalty Payments will be calculated based on related per-unit sales of covered products.

Earnings Per Share

Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period.  Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. During 2012 and 2011 we incurred losses; therefore, the effect of any Common Stock equivalent is anti-dilutive during those periods.

Concentration of Credit Risk and Other Risks and Uncertainties

Our cash and cash equivalents are primarily maintained at two financial institutions in the United States.  Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits.  The balances are insured by the Federal Deposit Insurance Corporation, or FDIC.  During the year ended December 31, 2012, 2011 and 2010, we had, at times, funds that were uninsured.  We do not believe that we are subject to any unusual financial risk beyond the normal risk associated with commercial banking relationships. We have not experienced any losses on our deposits of cash and cash equivalents.

Derivative Instruments

Our Series I Warrants contain an anti-dilution provision which prevents them from being considered indexed to our stock. As a result, the warrants are required to be accounted for as derivative instruments.

We recognize derivative instruments as either assets or liabilities on the accompanying Consolidated Balance Sheets at fair value. We record changes in the fair value (i.e., gains or losses) of the derivatives in the accompanying Consolidated Statements of Operations.

Impairment of Long-Lived Assets

We identify and record impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the carrying amount of an asset might not be recoverable, but not less than annually.  Recoverability is measured by comparison of the anticipated future net undiscounted cash flows to the related assets’ carrying value.  If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset.

Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

Because of our history of operating losses, we do not currently recognize the benefit of all of our deferred tax assets, including tax loss carry forwards, that may be used to offset future taxable income.  We continually assess our ability to generate sufficient taxable income during future periods in which our deferred tax assets may be realized.  If and when we believe it is more likely than not that we will recover our deferred tax assets, we will reverse the valuation allowance as an income tax benefit in our statements of operations.

Stock-based Compensation

We account for stock-based compensation using the fair value recognition method. We recognize these compensation costs net of the applicable forfeiture rate and recognize the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of 4 years. We estimate the forfeiture rate based on our historical experience.

In addition, we record stock and options granted to non-employees at fair value of the consideration received or the fair value of the equity investments issued as they vest over the performance period.

Fair Value

We apply fair value accounting to all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

Our financial instruments are stated at amounts that equal, or are intended to approximate, fair value.  When we approximate fair value, we utilize market data or assumptions that we believe market participants would use in pricing the financial instrument, including assumptions about risk and inputs to the valuation technique.  We use quoted valuation techniques, primarily the income and market approach that maximize the use of observable inputs and minimize the use of unobservable inputs for recurring fair value measurements.

22

New Accounting Pronouncements

In May 2011, the FASB issued a new accounting standard update, which amends the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for fiscal years beginning after December 15, 2011. This standard did not have an impact on our consolidated results of operations and financial position, when adopted on January 1, 2012.

On January 31, 2013 the FASB issued an update to an existing accounting standard the objective of which is to clarify the scope of Accounting Standards Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with Section 210-20-45 or Section 815-10-45 or are subject to a master netting arrangement or similar agreement.  Management does not expect adoption to have an effect on our consolidated results of operations and financial position.

On February 5, 2013 the FASB issued an amendment to a prior update of existing standards.   The amendments in this update supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in ASUs 2011-05 (issued in June 2011) and 2011-12 (issued in December 2011) for all public and private organizations. The amendments would require an entity to provide additional information about reclassifications out of accumulated other comprehensive income.  Management does not expect adoption to have an effect on our consolidated results of operations and financial position.

Impact of Recently Issued Accounting Pronouncements

New accounting guidance was issued in 2011 to require more prominent disclosure of comprehensive income. This guidance was effective for us beginning in the first quarter of 2012, and requires the presentation of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. We elected to present two separate but consecutive statements. New accounting guidance was issued in February 2013 that requires the presentation of information about the amounts reclassified out of accumulated other comprehensive income by component for each reporting period. This guidance is effective for us in the first quarter of 2013 and is not expected to have an effect on our financial condition or results of operations.

In addition, new accounting guidance was issued in 2011 and 2012 which was intended to reduce the complexity and costs of performing annual goodwill and indefinite-lived intangible asset testing by allowing companies the option to make a qualitative evaluation about the likelihood of impairment to determine whether it should calculate the fair value of a reporting unit or the indefinite-lived intangible asset. The adoption of this guidance did not have an effect on the Company’s financial condition or results of operations.

Operations (all amounts in this section are expressed in thousands)

Revenue

	2012		2011		2010
Revenue		412		20		68

Revenue generated for the year ended December 31, 2012 was approximately $412 compared to $20 for the year ended December 31, 2011 and $68 for the twelve months ended December 31, 2010. Our revenue in 2012, was as a result of entering into license agreements with our customers. In 2011 and 2010, revenue was solely limited to the royalties earned under our single license agreement through our Japanese subsidiary.  We expect the revenue from this license will continue to be insignificant in the future.  We do not intend to seek additional licenses or other revenue through our Japanese subsidiary.

Gain on Settlement

In June 2010, we received $200,000 from Microsoft Corporation related to a licensing agreement. We determined that we could not practically and objectively separate any settlement portion from the revenue element as discussed under the guidance of U.S. GAAP Accounting Standards Codification Topic 605: Revenue Recognition, or ASC Topic 605. As a result, this amount was classified as a gain on settlement. This reclassification had no impact on our net income, financial position or cash flows for any period. We did not receive a gain on settlement for the twelve months ended December 31, 2012 or 2011, respectively.

Royalty Expense

There was no royalty expense for the years ended December 31, 2012 and 2011 compared to $59,207 for the year ended December 31, 2010. Under our agreements with SAIC, we were obligated to pay SAIC 35% of the proceeds from the settlement of litigation with Microsoft after reduction for costs, including legal fees and expenses, incurred by us and SAIC in connection with the Microsoft litigation.

Research and Development Expenses

	2012		2011		2010
Research and Development		1,555		1,464		2,412

Research and development costs include expenses paid to outside development consultants and compensation-related expenses for our engineering staff. Research and development costs are expensed as incurred.

Our research and development expenses for the year ended December 31, 2012 was $1,555 compared to $1,464 for the year ended December 31, 2011 and $2,412 for the year ended December 31, 2010. The increase in 2012 was primarily due to the increase in bonuses paid in 2012 compared to 2011. The increase in 2010 as compared to 2012 and 2011, was primarily due to the increase in wages due to the dividend payment paid to our research and development staff.

Selling, General and Administrative Expenses

	2012		2011		2010
Selling, General and Administration		37,718		15,932		33,764

Selling, general and administrative expenses include compensation expense for management and administrative personnel, as well as expenses for outside legal, accounting, and consulting services.

Our selling, general and administrative expenses for the year ended December 31, 2012 was $37,718 compared to $15,932 for the year ended December 31, 2011 and $33,764 for the year ended December 31, 2010. The increase in 2012 and in 2010 was primarily due to the increase in legal fees associated with the settlement of the Aastra, Mitel and NEC cases as well as the ongoing Apples, Cisco and Avaya cases in 2012 and the Microsoft litigation in 2010. Legal fees represent approximately 71% of general and administrative expenses for 2012 as compared to 40% for 2011 and 75% for 2010.

Within selling, general and administrative expenses, legal fees for the year ended December 31, 2012 was $26,537 compared to $6,342 for the year ended December 31, 2011 and $25,353 for the year ended December 31, 2010. The increase in 2010 was primarily due to the increase in legal fees associated with the settlement of the Microsoft litigation.

Other Income and Expenses

	2012		2011		2010
Other Income and Expense		927		5,595		30,516

Our non-cash loss related to the periodic revaluation of our Series I Warrants liability for the year ended December 31, 2012 was $927 compared to $5,595 for the year ended December 31, 2011 and $30,516 for the year ended December 31, 2010.  Our non-cash loss related to the periodic revaluation of our Series I Warrants liability decreased by $4,668 in the year ended December 31, 2012, as compared to the comparable period in 2011 as a result of a higher common share price and warrant exercises during the year ended 2012.

Interest income for the year ended December 31, 2012 was $329 compared to $228 for the year ended December 31, 2011, and $1,310 for the year ended December 31, 2010. These changes are due to timing on the maturity of the investments as well as the amount of cash available for investments.

23

Liquidity and Capital Resources

For the year ended December 31, 2012, our cash and cash equivalents totaled $19,661 and our short-term investments totaled $26,493 compared to $49,482 and $14,438, respectively, for the year ended December 31, 2011 and $34,635 and $43,457, respectively, as of December 31, 2010.

Before entering into the Microsoft Settlement, we allocated a large amount of cash to legal fees and other expenses associated with the Microsoft litigation.  We expect that our cash and cash equivalents as of December 31, 2012, will be sufficient to fund our operations and provide working capital for general corporate purposes and legal expenses including the expenses for our ongoing complaints against Apple, Cisco, Siemens and Avaya in the United States District Court of the Eastern District of Texas, Tyler Division, as well as the complaint with the U.S. International Trade Commission, for at least the next 36 months.  While we do not expect to generate net income in the near term similar to in the net income generated during the year ended December 31, 2010, generally attributable to the Microsoft Settlement, we do expect to derive the majority of our future revenue from license fees and royalties associated with our patent portfolio, technology, software and secure domain name registry in the United States and other markets around the world over the long term.  However, we will not receive any proceeds from these claims unless and until they may be resolved in our favor, and we expect to continue to incur substantial legal and other costs associated with pursuit of our claims.

Contractual Commitments

The following table summarizes our contractual obligations, including interest expense, and commitments as of December 31, 2012:

Operating Obligations	Total		Less than 1 year		1 - 3 Years		3 - 5 Years		More than 5 Years
Operating Lease Obligations		46		46		---		---		---
Total		46		46		---		---		---

Off-Balance Sheet Arrangements

As of December 31, 2012, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk

We invest our excess cash primarily in highly liquid debt instruments of the time deposits, money market, and corporate debt securities. By policy, we limit the amount of credit exposure to any one issuer.

Investments in fixed rate earning securities carry a degree of interest rate risk. Fixed rate securities may have their fair market value adversely impacted due to a rise in interest rates. Due in part to these factors, our income from investments may decrease in the future.

We considered the historical volatility of short-term interest rates and determined that it was reasonably possible that an adverse change of 100 basis points could be experienced in the near term but would have an immaterial impact in the fair value of our marketable securities as they will be maturing in six months or less.

Although we have no obligation to settle our Series I Warrant obligations in cash or an unknown number of shares, the embedded liability in the Series I Warrant obligations is recorded at estimated fair value.  That estimated fair value is determined in large part by reference to our assumptions and estimates of various factors.  Notably, our liability will increase and we may incur significant non-cash expenses, all other factors being constant, if the market price of our common shares increases.  Conversely, our liability will decrease and we may recognize significant non-cash gains, all other factors being constant, if the market price of our common shares decreases.

We considered the historical volatility of our stock prices and determined that it was reasonably possible that the fair market value of our stock price could drastically increase in the near term but would have an immaterial impact to our consolidated balance sheets and statement of operations as there are only approximately 160,000 warrants outstanding.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

VirnetX Holding Corporation

We have audited the accompanying consolidated balance sheets of VirnetX Holding Corporation (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012. VirnetX Holding Corporation’s management is responsible for these consolidated financial statements.  Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits 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.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of VirnetX Holding Corporation, Inc. as of December 31, 2012and 2011, and the consolidated results of their operations, and cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), VirnetX Holding Corporation’s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 1, 2013 expressed an unqualified opinion as to the effectiveness of the Company’s control over financial reporting.

VirnetX Holding Corporation

NOTES TO FINANCIAL STATEMENTS

(in thousands except share and per share amounts)

Note 1 - Formation and Business of the Company

VirnetX Holding Corporation, which we refer to as” we”, “us”, “our”, “the Company” or “VirnetX”, is engaged in the business of commercializing a portfolio of patents. We seek to license our technology, including GABRIEL Connection Technology™, to various original equipment manufacturers, or OEMs, that use our technologies in the development and manufacturing of their own products within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets.    Prior to 2012 our revenue was limited to an insignificant amount of software royalties pursuant to the terms of a single license agreement.  During 2012 we had revenues from settlements of patent infringement disputes whereby we received consideration for past sales of licensees that utilized our technology, where there was no prior patent license agreement (see “Revenue Recognition).

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of VirnetX Holding Corporation and all wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to current year presentations.

Use of Estimates

We have made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues and expenses to prepare these financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) as delineated by the Financial Accounting Standards Board (FASB) in its Accounting Standards Codification (ASC). Generally, assets and liabilities that are subject to estimation and judgment include the fair value of stock-based compensation, the fair value of our warrant liability and deferred income taxes. While actual results could differ, we believe such estimates to be reasonable.

.

Revenue Recognition

We derive our revenue from patent licensing. The timing and amount of revenue recognized from each licensee depends upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements can be complex and may or may not include multiple elements. These agreements may include, without limitation, elements related to the settlement of past patent infringement liabilities, up-front and non-refundable license fees for the use of patents, patent licensing royalties on covered products sold by licensees, and the compensation structure and ownership of intellectual property rights associated with contractual technology development arrangements. Beginning January 1, 2011, licensing agreements are accounted for under the FASB revenue recognition guidance, "Revenue Arrangements with Multiple Deliverables." This guidance requires consideration to be allocated to each element of an agreement that has stand-alone value using the relative fair value method. In other circumstances, such as those agreements involving consideration for past and expected future patent royalty obligations, after consideration of the particular facts and circumstances, the appropriate recording of revenue between periods may require the use of judgment. In all cases, revenue is only recognized after all of the following criteria are met: (1) written agreements have been executed; (2) delivery of technology or intellectual property rights has occurred or services have been rendered; (3) fees are fixed or determinable; and (4) collectability of fees is reasonably assured.

Patent License Agreements: Upon signing a patent license agreement, we provide the licensee permission to use our patented technology in specific applications. We account for patent license agreements in accordance with the guidance for revenue arrangements with multiple deliverables and the guidance for revenue recognition. We have elected to utilize the leased-based model for revenue recognition, with revenue being recognized over the expected period of benefit to the licensee. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in specific applications and products:

Consideration for Past Sales: Consideration related to a licensee’s product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented technology prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive royalty for past sales in connection with the settlement of patent litigation where there was no prior patent license agreement. These amounts are negotiated based upon application of a royalty rate to historical sales prior to the execution of the license agreement. In each of these cases, since delivery has occurred, we record the consideration as revenue when we have obtained a signed agreement, identified a fixed or determinable price, and determined that collectability is reasonably assured.

Current Royalty Payments: These are ongoing royalty payments covering a licensee’s obligations to us related to its sales of covered products in the current contractual reporting period. Licensees that owe Current Royalty Payments are obligated to provide us with quarterly or semi-annual royalty reports that summarize their sales of covered products and their related royalty obligations to us. We expect to receive these royalty reports subsequent to the period in which our licensees’ underlying sales occurred. As a result, it is impractical for us to recognize revenue in the period in which the underlying sales occur, and, in most cases, we will recognize revenue in the period in which the royalty report is received and other revenue recognition criteria are met due to the fact that without royalty reports from our licensees, our visibility into our licensees’ sales is limited. Current Royalty Payments will be calculated based on related per-unit sales of covered products.

Revenues recognized during 2012 resulted from settlements of patent infringement disputes (see Note 15 “Litigation”) whereby we received consideration for past sales of licensees that utilized our technology, where there was no prior patent license agreement.

31

Cash and Cash Equivalents

We consider all highly liquid investments purchased with original maturities of three months or less at the date of purchase to be cash equivalents.  Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these investments.

Investments

Investments are classified as available-for-sale and are recorded at fair market value. Unrealized gain and losses are reported as other comprehensive income. Realized gains and losses are recorded in income in the period they are realized.  The Company's investments consist of debt securities and certificates of deposit with maturity dates primarily less than nine months.

Property and Equipment

Property and equipment are stated at historical cost, less accumulated depreciation and amortization.  Depreciation and amortization are computed using the accelerated and straight line methods over the estimated useful lives of the assets, which range from five to seven years.  Repair and maintenance costs are charged to expense as incurred.

Concentration of Credit Risk and Other Risks and Uncertainties

Our cash and cash equivalents are primarily maintained at two major financial institutions in the United States.  Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits.  A portion of those balances are insured by the Federal Deposit Insurance Corporation, or FDIC.   During the year ended December 31, 2012, we had, at times, funds that were uninsured.  We do not believe that we are subject to any unusual financial risk beyond the normal risk associated with commercial banking relationships. We have not experienced any losses on our deposits of cash and cash equivalents.

Fair Value

The carrying amounts of our financial instruments, including cash equivalents, accounts payable, and accrued liabilities, approximate fair value because of their generally short maturities.

Intangible Assets

We record intangible assets at cost, less accumulated amortization.  Amortization of intangible assets is provided over their estimated useful lives, which can range from 3 to 15 years, on either a straight-line basis or as revenue is generated by the assets.

Impairment of Long-Lived Assets

We identify and record impairment losses on long-lived assets used in operations when events and changes in circumstances indicate that the carrying amount of an asset might not be recoverable, but not less than annually.  Recoverability is measured by comparison of the anticipated future net undiscounted cash flows to the related assets’ carrying value.  If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset.

Research and Development

Research and development costs include expenses paid to outside development consultants and compensation related expenses for our engineering staff.  Research and development costs are expensed as incurred.

Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carry forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We are subject to examinations by the Internal Revenue Service (“IRS”) and other taxing jurisdictions on various tax matters, including challenges to various positions we assert in our filings. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.

The financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable tax authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.  See Note 11, “Income Taxes” for additional information.

Derivative Instruments

Our Series I Warrants are accounted for as derivative instruments as a result of an anti-dilution provision which, in accordance with U.S. GAAP, prevents them from being considered indexed to our stock and qualified for an exception to derivative accounting.

We recognize derivative instruments as either assets or liabilities on the accompanying Consolidated Balance Sheets at fair value.  We record changes in the fair value (i.e., gains or losses) of the derivatives in the accompanying Consolidated Statements of Operations.

32

Stock-Based Compensation

We account for stock-based compensation using the fair value recognition method in accordance with U.S. GAAP. We recognize these compensation costs net of the applicable forfeiture rate and recognize the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of 4 years. We estimate the forfeiture rate based on our historical experience if any. See Note 6 - Stock-Based Compensation for additional information concerning our share-based compensation awards.

In addition, as required we record stock and options granted to non-employees at fair value of the consideration received or the fair value of the equity instruments issued as they vest over the performance period.

Earnings Per Share

Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period.  Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. During 2012 and 2011 we had incurred losses; therefore the effect of any common stock equivalent would be anti-dilutive during these periods.

New Accounting Pronouncements

In May 2011, the FASB issued a new accounting standard update, which amends the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for fiscal years beginning after December 15, 2011. This standard did not have an impact on our consolidated results of operations and financial position, when adopted on January 1, 2012.

On January 31, 2013 the FASB issued an update to an existing accounting standard the objective of which is to clarify the scope of Accounting Standards Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with Section 210-20-45 or Section 815-10-45 or are subject to a master netting arrangement or similar agreement.  Management does not expect adoption to have an effect on our consolidated results of operations and financial position.

On February 5, 2013 the FASB issued an amendment to a prior update of existing standards.   The amendments in this update supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in ASUs 2011-05 (issued in June 2011) and 2011-12 (issued in December 2011) for all public and private organizations. The amendments would require an entity to provide additional information about reclassifications out of accumulated other comprehensive income.  Management does not expect adoption to have an effect on our consolidated results of operations and financial position.

Impact of Recently Issued Accounting Pronouncements

New accounting guidance was issued in 2011 to require more prominent disclosure of comprehensive income. This guidance was effective for us beginning in the first quarter of 2012, and requires the presentation of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. We elected to present two separate but consecutive statements. New accounting guidance was issued in February 2013 that requires the presentation of information about the amounts reclassified out of accumulated other comprehensive income by component for each reporting period. This guidance is effective for us in the first quarter of 2013 and is not expected to have an effect on our financial condition or results of operations.

In addition, new accounting guidance was issued in 2011 and 2012 which was intended to reduce the complexity and costs of performing annual goodwill and indefinite-lived intangible asset testing by allowing companies the option to make a qualitative evaluation about the likelihood of impairment to determine whether it should calculate the fair value of a reporting unit or the indefinite-lived intangible asset. The adoption of this guidance did not have an effect on the Company’s financial condition or results of operations.

Note 3 - Property and Equipment

Our major classes of property and equipment were as follows:

	December 31
	2012			2011			2010
Office furniture	$	70		$	57		$	22

	$	70		$	56		$	25

Depreciation expense for the years ended December 31, 2012, 2011, 2010 was $23, $20 and $11 respectively.

Note 4 - Commitments

We lease our offices under an operating lease with a third party expiring in October 2013.  We recognize rent expense on a straight-line basis over the term of the lease. Rent expense was $56, $59 and $52 for the years ended December 31, 2012, 2011 and 2010 respectively.

For the Year	Minimum Required Lease Payments in Period

Note 5 - Stock Plan

In 2005, VirnetX, Inc. adopted the 2005 Stock Plan (the "Plan"), which was assumed by us upon the closing of the transaction between VirnetX Holding Corporation and VirnetX, Inc. on July 5, 2007.  Our Board of Directors renamed this Plan the VirnetX Holding Corporation 2007 Stock Plan and our stockholders approved the Plan at our 2008 annual stockholders' meeting.  The Plan provides for the issuance of up to 11,624,469 shares of our common stock.  To the extent that any award should expire, become un-exercisable or is otherwise forfeited, the shares subject to such award will again become available for issuance under the Plan.  The Plan provides for the granting of stock options and restricted stock purchase rights (RSU) to our employees and consultants.  Stock options granted under the Plan may be incentive stock options or nonqualified stock options.  Incentive stock options ("ISO") may only be granted to our employees (including officers and directors).  Nonqualified stock options ("NSO") and stock purchase rights may be granted to our employees and consultants.

The Plan will expire 10 years after it was approved by our Board of Directors.  Options may be granted under the Plan with an exercise price determined by our Board of Directors, or a duly appointed committee thereof, provided, however, that the exercise price of an option granted to any employee shall be not less than 100% of the fair market value at the date of grant in the case of ISO or 85% of the case of an NSO,  the exercise price of an ISO or NSO granted to one of our Named Executive Officers shall not be less than 100% fair market value of the shares at the date of grant and the exercise price of an ISO granted to a 10% shareholder shall not be less than 110% of the fair market value of the shares on the date of grant.  Stock options granted under the Plan typically vest over four years and have a 10 year term.  All RSUs are considered to be granted at the fair value of our stock on the date of grant because they have no exercise price. RSUs typically vest over four years.

Activity under the Plan is as follows:

	Options Outstanding

Intrinsic value is calculated as the difference between the per share market price of our common stock on the last trading day of 2012, which was $29.28, and the exercise price of the options.  For options exercised, the intrinsic value is the difference between market price and the exercise price on the date of exercise. We received cash proceeds of $1,691and $1,068 from stock options exercised in 2012 and 2011, respectively. The total intrinsic value of options exercised was $11,509, $8,050 and $7,350 during the years ended December 31, 2012, 2011 and 2010, respectively.  The aggregate intrinsic value of options exercisable at December 31, 2012 was $99,723.

Stock-based compensation expense is included in general and administrative expense for each period as follows:

Stock-Based Compensation by Type of Award	Year Ended December 31, 2012		Year Ended December 31, 2011		Year Ended December 31, 2010
Employee stock options	$	5,171	$	4,367	$	3,381
RSU’s		991		—		—
Total stock-based compensation expense	$	6,162	$	4,367	$	3,381

As of December 31, 2012, there was $12,883 of unrecognized stock-based compensation expense expected to be recognized related to unvested employee stock options and $2,891 of unrecognized stock-based compensation expense to be recognized related to unvested RSU’s. These costs are expected to be recognized over a weighted-average period of 1.36 and 2.81 years, respectively.

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model using the following weighted average assumptions:

	Year Ended December 31, 2012			Year Ended December 31, 2011			Year Ended December 31, 2010
Expected stock price volatility		111	%		123	%		110	%
Risk-free interest rate		1.90	%		3.05	%		3.66	%
Expected life term (in years)	6.8		years	6.6		years	7.0		years
Expected dividends		0	%		0	%		0	%

Based on the Black-Scholes option pricing model, the weighted average estimated fair value of employee stock options granted was $23.15, $21.13 and $4.83 during the years ended December 31, 2012, 2011 and 2010 respectively.

The expected life was determined using the simplified method outlined in ASC 718, taking the average of the vesting term and the contractual term of the option.  Expected volatility of the stock options was based upon historical data and other relevant factors, such as the volatility of comparable publicly-traded companies at a similar stage of life cycle.  We have not provided an estimate for forfeitures because we have no history of forfeited options and believe that all outstanding options at December 31, 2012, will vest.  In the future, the Company may change this estimate based on actual and expected future forfeiture rates.

Note 7 - Earnings Per Share

Basic earnings per share are based on the weighted average number of shares outstanding for a period.  Diluted earnings per share are based upon the weighted average number of shares and potentially dilutive common shares outstanding.  Potential common shares outstanding principally include stock options, under our stock plan and warrants. During 2012 and 2011, we incurred losses; therefore the effect of any common stock equivalent would be anti-dilutive during those periods.

The table below sets forth the basic loss per share calculations:

	Period Ended December 31,
	2012			2011			2010
Net income (loss)	$	(26,924	)	$	(17,263	)	$	41,417
Basic weighted average number of shares outstanding		50,934			50,028			45,453
Diluted weighted average number of shares outstanding		50,934			50,028			49,067
Basic earnings (loss) per share	$	(0.53	)	$	(0.35	)	$	0.91
Diluted earnings (loss) per share	$	(0.53	)	$	(0.35	)	$	0.84

Options to purchase 2.3 million shares at prices ranging from $0.24 to $6.47 were excluded from the diluted earnings per share calculation for the year ending December 31, 2010 because they would have been anti-dilutive due to their exercise prices exceeding the average market prices for the period.

Note 8 - Common Stock

Each share of common stock has the right to one vote.  The holders of common stock are entitled to receive dividends whenever funds are legally available and when declared by our Board of Directors, subject to the prior rights of holders of all classes of stock outstanding having priority rights as to dividends.  On June 15, 2010, the Company's Board of Directors declared a special cash dividend of $0.50 per share of the Company's common stock to holders of record on July 1, 2010.  Our restated articles of incorporation authorize us to issue up to 100,000,000 shares of $.0001 par value common stock.

Note 9 - Warrants

Information about warrants outstanding during the twelve months ended December 31, 2012 follows:

Original Number of Warrants Issued			Exercise Price per Common Share		Exercisable at December 31, 2011		Became Exercisable		Exercised			Terminated / Cancelled / Expired		Exercisable at December 31, 2012		Expiration Date

Note 10 - Employee Benefit Plan

We sponsor a defined contribution, 401k plan, covering substantially all our employees.  The Company's matching contribution to the plan was approximately, $41 in 2012, $36 in 2011 and $36 in 2010.

Note 11 - Income Taxes

The (benefit) provision for income taxes is comprised of the following:

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of deferred assets will not be realized.  The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.

Based on the available objective evidence, we believe it is more likely than not that the net deferred tax assets as of December 31, 2012 will not be fully realizable. Accordingly, management has established a full valuation allowance against its net deferred tax assets at December 31, 2012. The net change in the total valuation allowance for the year ended December 31, 2012 was an increase of $802. At December 31, 2012, the Company has federal and state net operating loss carry forwards of approximately $912 and $39,432, respectively expiring in 2027 and 2012, respectively. At December 31, 2012, the Company has federal research and development credits carry forwards of approximately zero expiring beginning in 2031.

Internal Revenue Code Section 382 places a limitation (the "Section 382 Limitation") on the amount of taxable income can be offset by net operating loss carry forwards after a change in control (generally greater than 50% change in ownership) of a loss corporation. California has similar rules. Our capitalization described herein may have resulted in such a change. Generally, after a control change, a loss corporation cannot deduct net operating loss carry forward in excess of the Section 382 Limitation. Management has analyzed the utilization of its net operating loss carry forward against taxable income in future periods and determined on a more likely than not basis it will be able to use all its recognized net operating losses before they expire.

We are required to recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. As a result, we have provided contingent reserve under ASC 740-10 of $128 and $128 at December 31, 2012 and December 31, 2011, respectively. Our tax returns are subject to review by various tax authorities. The returns are subject to review those from 2005 forward.

Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We did not have associated accrued interest or penalties nor was any interest expense or penalties recognized during the year ended December 31, 2012.

A reconciliation of beginning and ending amounts of unrecognized tax benefits follows:

	Year Ended December 31, 2012		Year Ended December 31, 2011		Year Ended December 31, 2010

Note 12 - Fair Value Measurement

We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The carrying amounts for cash and cash equivalents, investments in certificates of deposit, accounts payable and accrued expenses approximate their fair values due to the short period of time until maturity.

Certificate of deposits: Fair value measured at face value plus accrued interest.

Corporate bonds:  Fair value measured at the closing price reported on the active market on which the individual securities are traded.

Series I Warrants: Fair value measured by using a Binomial valuation model. As of December 31, 2012, the assumptions used to measure fair value of the liability embedded in our outstanding Series I Warrants included a warrant exercise price of $3.59 per share, a common share price of $29.28, a discount rate of 0.72%, and a volatility of 94.15%. As of December 31, 2011, the assumptions used to measure fair value of the liability embedded in our outstanding Series I Warrants included a warrant exercise price of $3.59 per share, a common share price of $24.97, a discount rate of 0.83%, and a volatility of 123%.

The following table sets forth by level, within the fair value hierarchy, our financial instrument assets as of December 31, 2012 (in thousands):

Note 13 - Patent Portfolio

As of December 31, 2012, we own 20 issued U.S. and 32 issued foreign patents, in addition to several pending U.S. and foreign patent applications.  Our issued U.S. and foreign patents expire at various times during the period from 2019 to 2024.  Some of our issued patents and pending patent applications were acquired by our principal operating subsidiary, VirnetX, Inc., from Science Applications International Corporation, or SAIC, in 2006 and we are required to make payments to SAIC based on cash or certain other values generated from those patents.  The amount of such payments depends upon the type of value generated, and certain categories are subject to maximums and other limitations. As of June 30, 2010, we met our maximum royalty payment requirement; however, SAIC is also entitled under certain circumstances to receive a portion of the proceeds paid to us for certain acquisitions of VirnetX or from the settlement of certain patent infringement claims of ours.

As of December 31, 2012, the expected future amortization of the intangible assets is as follows:

Note 14 - Litigation

We have four intellectual property infringement lawsuits pending against multiple parties in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief in all the complaints. We have one complaint with the United States International Trade Commission (ITC) alleging that Apple, Inc. has engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain devices with secure communication capabilities that infringe one or more claims of our U.S. Patent No. 8,051,181. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.’s infringement through the district courts.

VirnetX Inc. v. Cisco Systems, Inc. et al

On August 11, 2010, we initiated a lawsuit by filing a complaint against Aastra, Apple, Cisco, and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these parties infringe on certain of our patents. We seek damages and injunctive relief. On February 4, 2011, we amended our original complaint, filed on August 11, 2010, against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to assert U.S. Patent No. 7,418,504 against Apple and Aastra. On April 5, 2011, we again amended our complaint against Aastra, Apple, Cisco and NEC in the United States District Court for the Eastern District of Texas, Tyler Division, to include Apple’s iPad 2 in the list of Apple products that are accused of infringing our patents. We also asserted our newly-issued patent, U.S. Patent No. 7,921,211 against all of the defendants in that lawsuit. A claim construction hearing was held on January 5, 2012 and the court issued a Markman ruling on April 25, 2012. Aastra and NEC have signed license agreements with us and we have dismissed the patent infringement cases against them. At the pre-trial hearing, the judge decided to postpone the trial against Cisco to March 4, 2013 and just try the case against Apple. On November 6, 2012, a Jury in the United States Court for the Eastern District of Texas, Tyler Division, awarded us over $368,000,000 in a verdict against Apple Corporation for infringing four of our patents. A post-trial hearing in the case against Apple was held on December 20, 2012. On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the prior jury verdict. The Court denied Apple’s motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple’s request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. Specifically, the Court ordered that Apple pay $33,561 in daily interest up to final judgment and $330,201 in daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. In doing so, the Court ordered the parties to mediate over a license in the following 45 days for Apple’s future infringing use not covered by the Court’s Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court. The preparations for the jury trial against Cisco on March 4, 2013 are underway.

VirnetX Inc. v. Mitel Networks Corporation et al

On January 12, 2011, we initiated a lawsuit by filing a complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that these companies infringe three of our patents.  We seek damages and injunctive relief. On April 12, 2011 we again amended our complaint against Siemens and Mitel in the United States District Court for the Eastern District of Texas, Tyler Division, to add Avaya Inc. as a defendant. On July 11, 2012, Mitel Network Corporation signed a license agreement with us and we dismissed the patent infringement case against them. On July 12, 2012 we had a claims construction hearing in this case and a markman order was issued on August 1, 2012. On January 29, 2013 Siemens signed a license agreement with us and we dismissed the patent infringement case against them. The preparations for the jury trial against Avaya on March 4, 2013 are underway.

VirnetX Inc. v. Apple, Inc

On November 1, 2011, we initiated a lawsuit against Apple in the United States District Court, Tyler Division, pursuant to which we allege that Apple infringes one or more claims of our U.S. Patent No. 8,051,181.  We seek damages and injunctive relief.  No hearing or trial dates have been set.

VirnetX Inc. v. Apple, Inc.

On November 6, 2012, we filed a new complaint against Apple Inc., in the United States District Court for the Eastern District of Texas, Tyler Division for willfully infringing four of our patents, U.S. Patent Nos. 6,502,135, 7,418,504, 7,921,211 and 7,490,151, and seeking both damages and injunctive relief. The accused products include the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad mini, and the latest Macintosh computers. Due to their release dates, these products were not included in the previous lawsuit that concluded with a Jury verdict on November 6, 2012 that was subsequently upheld by the United States District Court for the Eastern District of Texas, Tyler Division, on February 26, 2013.

ITC Investigation No. 337-TA-858

On July 18, 2012, the Administrative Law Judge (ALJ) assigned to investigate our complaint, against Apple Inc., identified a procedural discrepancy with our complaint and dismissed it. On September 14, 2012, we re-filed our complaint with the ITC jointly with Science Applications International Corporation (SAIC) [NYSE: SAI] to remove a procedural standing issue that was identified as the reason for dismissal of our previous complaint. On October 16, 2012, the United States International Trade Commission (ITC) accepted our complaint and instituted an investigation against Apple and assigned ALJ E. James Gildea to preside over this investigation. Subsequently on October 23, 2012, the ALJ issued an order setting February 21, 2014 as the target date for completion of this investigation. The hearing in-front of ALJ is scheduled for May 20, 2013. On February 27, 2013, we announced our intent to withdraw our complaint with the ITC and pursue comprehensive relief from Apple Inc.’s infringement through the district courts.

One or more potential intellectual property infringement claims may also be available to us against certain other companies who have the resources to defend against any such claims.  Although we believe these potential claims are worth pursuing, commencing a lawsuit can be expensive and time-consuming, and there is no assurance that we will prevail on such potential claims.  In addition, bringing a lawsuit may lead to potential counterclaims which may preclude our ability to commercialize our initial products, which are currently in development.

Note 16. Subsequest Event

On January 29, 2013, we entered into a License Agreement with Siemens Enterprise Communications GmbH & Co. KG, and Siemens Enterprise Communications Inc.. Under the terms of the Agreement, the Parties have agreed to dismiss the patent infringement case between the Parties and their affiliates before the U.S. District Court for the Eastern District of Texas.

On February 26, 2013, the United States District Court for the Eastern District of Texas, Tyler Division issued its Memorandum Opinion and Order regarding post-trial motions resulting from the November 6, 2012 jury verdict against Apple, Inc. The Court denied Apple’s motion to reduce the damages awarded by the jury for past infringement. The Court further denied Apple’s request for a new trial on the liability and damages portions of the verdict. Additionally, the Court granted our motions for pre-judgment interest, post-judgment interest, and post-verdict damages to date. The Court ordered that Apple pay daily interest up to final judgment and daily damages for infringement up to final judgment for certain Apple devices included in the verdict. The Court denied our request for a permanent injunction. The Court has ordered the parties to mediate over a license in the following 45 days for Apple’s future infringing use not covered by the Court’s Order. If the parties fail to agree to a license, the Court requested that we file the appropriate motion with the Court for its assistance. There can be no assurance a license agreement can be reached. Due to the remaining uncertainty regarding the conclusion of this litigation, the financial statements do not include any provision for gains or losses regarding this matter.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and

Stockholders of VirnetX Holding Corporation

We have audited the internal control over financial reporting of VirnetX Holding Corporation (the “Company”) as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audit also included performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2012, of the Company and our report dated March 1, 2013, expressed an unqualified opinion on those financial statements.

Item 9A.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation 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) under the Securities Exchange Act of 1934, as amended, December 31, 2012.

The purpose of this evaluation was to determine whether as of December 31, 2012 our disclosure controls and procedures were effective to provide reasonable assurance that the information we are required to disclose in our filings with the SEC, (i) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of December 31, 2012, our disclosure controls and procedures were effective.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the company. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2012. There were no changes in our internal control over financial reporting during the quarter ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Farber Hass Hurley LLP has audited our internal control over financial reporting as of December 31, 2012; their report is included elsewhere herein.
