Tumbleweed MailGate

Tumbleweed MailGate is a suite of products for protecting, filtering, monitoring, and securing email communications. These products, which can be used individually or in combination, enable organizations to block threats at multiple points in their email networks and dynamically encrypt and route email messages based on administrator-defined policies and industry regulations. Products in the MailGate family, which is a winner of the 2006 “Recommended “Product Rating from Secure Computing magazine, include:

MailGate Email Firewall: our comprehensive email security solution for email threat prevention, content filtering and email encryption capabilities.

SecureTransport has been deployed at financial services, health care, and government sites around the world.

Tumbleweed Validation Authority

The Tumbleweed Validation Authority is the world’s most widely deployed Online Certificate Status Protocol (“OCSP”) responder. It validates the revocation status of any digital certificate in real-time, and is Identrus and Joint Interoperability Technology Center (“JITC”) certified. Many banks, governments and businesses have deployed Public Key Infrastructures (“PKI”) to secure everything from corporate network access to multi-million dollar electronic transactions. PKI systems depend on the use of digital certificates. Tumbleweed

Validation Authority delivers a comprehensive, scaleable framework for real-time validation of digital certificates issued by any certificate authority.

Industry Background

The use of corporate email systems, customer service applications and web services has grown as enterprises increasingly rely on these applications to communicate with their customers, business partners, and suppliers. Enterprises seek communications applications that integrate business processes and associated data with email and web applications and transform how they communicate and conduct business with their customers and partners. The volume of corporate Internet communications has grown significantly over the past several years in both the business and consumer markets. However, these systems are increasingly challenged by the threats of hackers, viruses, spam overload, email spoofing and phishing attacks.

To fully leverage the power of communicating using the Internet and email, businesses must first address the issues of security, centralized management, automation, legacy integration, and end-user behavior, as well as potential adoption issues. The policies and management protocols traditionally applied to paper or voice-based processes within a company in many cases are now being applied, appropriately, to email communications. The adoption of these policies and protocols is critical to establish compliance with regulatory requirements and to provide enterprises the same audit trail and confidentiality protections that paper processes supply. End-users are also interested in easily accessible online services and communications from the companies with which they do business.

With comprehensive communication security solutions, businesses can deploy policies enterprise-wide, provide critical management of communications, and leverage the investment they have made in their existing systems in order to maximize business conducted on the Internet.

Tumbleweed’s Messaging Security Solutions and Services

We offer a comprehensive family of messaging security software and appliance solutions that enable enterprises to leverage the cost-efficiencies and productivity of Internet communications. In addition, all of our solutions are designed to integrate with existing business and email systems, requiring no significant change in existing firewall or system infrastructures. Our solutions can be used independently or in combination to create a secure Internet communications solution for businesses. All of our solutions offer multi-level security using industry standards, universal access, and proven scalability for high volume message traffic.

Tumbleweed MailGate Suite

The Tumbleweed MailGate Suite is a family of products for protecting, filtering and monitoring email for enterprises and governments. These best-in-breed products enable businesses to manage inbound and outbound traffic, block threats, encrypt messages and optimize network performance.

The MailGate Suite is unique both in its depth and breadth. Unlike competitors who rely on other vendors for encryption and anti-spam technology, Tumbleweed has developed native, integrated components that ensure scalability and interoperability. The MailGate family of products allows organizations to:

Protect their network: MailGate stops attacks (e.g. virus, spam, worms, denial of service and directory harvest) both at the demilitarized zone and within the corporate network.

Comply with regulations and policies: MailGate has one of the most comprehensive content filtering and intelligent routing capabilities.

Secure private information: MailGate provides industry-leading encryption technology, automatically securing and routing messages based on customer-defined policies and practices.

Reduce communication costs: MailGate eliminates potentially costly threats (viruses, denial of service/directory harvest, spam), and ensures optimal network performance.

Tumbleweed SecureTransport Suite

Tumbleweed SecureTransport is a comprehensive enterprise secure file transfer solution that enables the exchange of valuable and sensitive data over the Internet in a secure and reliable manner. SecureTransport is a centrally managed, client-server solution supporting a broad set of open standard file transfer protocols, including File Transfer Protocol, or FTP, secure FTP; HyperText Tranfer Protocol, or HTTP; Secure HTTP, or HTTPS; Secure Shell, or SSH; and Applicability Standard #2, or AS2.

SecureTransport forms the core of many financial networks, healthcare agencies, and state, local and federal governments. Financial networks use SecureTransport to move billions of dollars of financial transactions daily. Healthcare providers, payers, producers and clearing houses are linked through SecureTransport, transferring private health information. Government agencies leverage SecureTransport to communicate and share documents with other agencies and to replace outdated forms of data transfers such as EDI, leased lines, and un-secure FTP.

With SecureTransport, organizations can:

Consolidate disparate systems: Many organizations have developed home-grown file transfer applications that don’t scale or interoperate. Based on standards and supporting multiple protocols, SecureTransport is a cost-effective, scaleable alternative.

Automate and streamline applications: SecureTransport enables organizations to easily convert paper-based or proprietary electronic transfers to a secure, standards-based Internet model.

Comply with policies and regulations: SecureTransport enables organizations to securely send and receive private information in conformance with industry, government or corporate regulations.

Utilize AS2 for efficient transactions: SecureTransport enables businesses to conduct EDI and business-to-business transactions without VPNs, additional infrastructure or proprietary software.

Tumbleweed Validation Authority Suite

The Tumbleweed Validation Authority is the world’s most widely deployed OCSP responder. It validates the revocation status of any digital certificate in real-time, and is Identrus and JITC certified. Many banks, governments and businesses have deployed PKI to secure everything from corporate network access to multi-million dollar electronic transactions. PKI systems depend on the use of digital certificates. These virtual IDs, which are issued by independent certificate authorities, provide a way to authenticate the identity of an individual, an organization, or a computer. However, like physical credentials used in the real world— such as passports, credit cards, and security badges—digital certificates are sometimes found to be expired, revoked or suspended. The integrity of an organization’s PKI system is only as reliable as its ability to check the validity of a certificate the moment it is presented. Tumbleweed Validation Authority delivers a comprehensive, scaleable framework for real-time validation of digital certificates issues by any certificate authority.

Tumbleweed Professional Services

The following are examples of the professional services we offer:

 

    Support and maintenance, which assists customers in managing Tumbleweed products they have deployed;

 

    Integration consulting, which allows our customers to integrate our solutions with existing technology infrastructure, including legacy systems, customer databases, support systems, and billing systems; and

 

    Technical training, which provides the customer with formal training in the administration and operation of our products and use of our application programming interfaces, or APIs.

Table of Contents

Our products are generally deployed in business-critical environments, where highly responsive customer support is critical to the continuing success of the deployed solution. We maintain a technical support group that is responsible for first-line and second-line customer support as well as distribution of products and documentation updates. This group works closely with our professional services and product development organizations in order to ensure continuity in the areas of problem resolution and priority response.

We also offer extended customer assistance 24 hours a day, 7 days a week, for those customers requiring around-the-clock support. Pricing for such support is in addition to our standard maintenance fees.

Professional services are performed for an additional fee and are offered in conjunction with the licensing or deployment of our products.

Strategy

Our objective is to be the leading provider of secure Internet communication software and appliance products for enterprises and government. Key elements of our strategy are:

 

    Growing our existing position in the financial services, healthcare, and government industries and expanding into additional industries;

 

    Expanding our distribution channels, including our reseller channel, to increase sales to the mid-sized enterprise market;

 

    Expanding our international sales presence;

 

    Leveraging our security core competency and intellectual property to increase our market share and mind share in the email security and secure file transfer markets: and

 

    Expanding our market share through the continued introduction of new and enhanced functionality in the email security, secure file transfer and validation products.

Customers

We provide our customers with secure Internet communication solutions. We are trusted by approximately 1,600 enterprise and government customers who use our products to connect with over ten thousand corporations and millions of end-users. Our market focus is in the financial services, healthcare, and government markets. Our products are sold directly and through channel partners to enterprises and governments.

For 2005, 2004, and 2003, five customers comprised approximately 11%, 12%, and 16%, respectively, of our revenue. The loss of one or more of our major customers, the failure to attract new customers on a timely basis or a reduction in usage and revenue associated with the existing or proposed customers would harm our business and prospects. For the years ended December 31, 2005, 2004, and 2003, respectively, no single customer comprised 10% or more of our revenue.

Backlog

Our backlog consists of deferred revenue as well as contractual commitments that are not due and payable as of the balance sheet date, or for which collectibility is in doubt, and/or for which the product or service has not yet been delivered. Our backlog excludes all items relating to consulting and training services. Backlog was $23.4 million and $20.4 million at December 31, 2005 and 2004, respectively. We believe that $17.6 million of the backlog at December 31, 2005 will be recognized as revenue in 2006 in accordance with our revenue recognition policy, with the balance to be recognized thereafter.

Sales

We maintain a direct sales force that focuses on signing key enterprise and government customers as well as further penetrating existing accounts by selling them new or expanded applications. Our sales force consists of a total of 74 employees as of December 31, 2005. Sales offices currently include Redwood City, California; McLean, Virginia; Hurst, United Kingdom; New York, New York; Oakbrook Terrace, Illinois; and Singapore. Our sales force includes field sales engineers and inside sales personnel who support the account executives. Field sales engineers assist our account executives with technical presentations, customer requirements analysis and initial solution designs. Our inside sales personnel assist the account executives in managing their customer relationships and qualifying new accounts. Our sales effort is augmented by the sales forces of our channel partners. The typical sales cycle can range from one to nine months, but may be longer for large contracts.

Marketing

Our marketing strategy is to raise awareness of the ever-expanding security risks associated with organizations conducting business online, and increase recognition of Tumbleweed as a strategic supplier of solutions which mitigate these risks. We raise awareness and increase Tumbleweed mindshare through targeted, integrated campaigns highlighting both our company and our product offerings. These campaigns translate into sales opportunities for both our direct sales force and our channel partners.

Our marketing efforts are organized around three primary areas: product marketing, product management and corporate marketing. Product marketing identifies target markets and customer opportunities, and develops the positioning, programs and materials to reach customers and support sales activities. Product management translates customer and market requirements into product plans and works with our engineering team to ensure completion. Product management also trains salespeople on product information. Corporate marketing drives overall market awareness of Tumbleweed as a company and of our products through analyst and investor relations, media, events, and speaking engagements. Corporate marketing is also responsible for branding, corporate identity, and our website. Both product marketing and corporate marketing work closely with direct sales and channel sales partners to focus programs more effectively and guide product research and development.

Governmental Regulation

All of our products are subject to U.S. export control laws and applicable foreign government import, export and/or use requirements. Minimal U.S. export restrictions apply to all products, whether or not they perform encryption functions.

The Export Administration Regulations of the U.S. Department of Commerce regulate the export of most commercial products with encryption features. Under regulations issued by the Department of Commerce in January 2000, encryption products of any key length may be exported, after a one-time technical review, to non-governmental end-users around the world, except for embargoed countries and specific prohibited end-users. Encryption products may be exported to governmental end-users under special Encryption Licensing Arrangements or individual export licenses that may be issued at the discretion of the Department of Commerce. In October 2000, the Department of Commerce further revised the Export Administration Regulations to relax some reporting requirements and to remove the export licensing requirement for shipments to governmental end-users in 23 countries, including most of the United States’ major trading partners. In June 2002, the Department of Commerce amended the encryption regulations again to conform them to the control lists implemented by other countries that are also members of the Wassenaar Arrangement. We believe that we have completed the necessary technical reviews of the products and services we currently export, but new products that we acquire or develop may require technical review before we can export them. For the export of some of our products, we are subject to various post-shipment reporting requirements.

Table of Contents

The changes to the export regulations allow our products to be exported more quickly and at stronger strength and, therefore, be more competitive with products from foreign producers. However, the export regulations may be modified at any time. In light of the ongoing discussions regarding anti-terrorism legislation in the U.S. Congress, there may be an increased risk that export regulations may be modified in the future. Modifications to the export regulations could reduce or eliminate our ability to export some or all of our products from the U.S. without a license in the future, which could put us at a disadvantage in competing for international sales compared to companies located outside of the U.S. that would not be subject to these restrictions.

Intellectual Property

We own 23 U.S. patents issued by the U.S. Patent and Trademark Office including 22 utility patents and one design patent. We have filed additional utility patent applications that are now pending in the U.S. Patent and Trademark Office, and also have numerous patent applications now pending in foreign jurisdictions. In addition, we currently have 22 registered trademarks worldwide, including the mark Tumbleweed, and are pursuing other key trademarks and service marks in the U.S. and internationally.

Competition

The markets in which we compete are intensely competitive and rapidly changing. We believe there is no single competitor that offers the complete package of secure Internet communication solutions that we sell. We are aware of competitors that exist for each of our product lines and for some combined components of our solution sets.

Our principal competition for our MailGate email security solutions are companies that offer various email content filtering and anti-spam products. Some of the companies that sell products that compete with some of the features within our products include CipherTrust, Inc., Clearswift Limited, IronPort Systems, Inc., Proofpoint, Inc., Symantec Corp., and Zix Corporation.

Our principal competition for our SecureTransport solutions comes from software and service providers that include Axway and Sterling Commerce (a division of SBC Communications, Inc).

Our principal competition for our Validation Authority solution comes primarily from software providers including Alacris Inc., CoreStreet Ltd., and SyTrust Technologies GmbH.

In addition to the competitors listed above, companies with which we do not presently directly compete may become competitors in the future, either through the expansion of our products or through their product development in the area of secure online communication services. These companies could include International Business Machines Corporation/Lotus Development, and Microsoft Corp.

Employees

As of December 31, 2005, we employed 320 people worldwide, including 162 in engineering, 74 in sales, 49 in professional services, 10 in marketing, and 25 combined in corporate management, finance, hardware operations, human resources, information technology, legal, and other administration. Our employees are not represented by any collective bargaining organization. We have never experienced a work stoppage and consider our relations with our employees to be good.

Our Executive Officers

Listed below are our executive officers as of March 16, 2006. There are no family relationships between any of the executive officers and there is no arrangement or understanding between any executive officer and any other person pursuant to which the executive officer was selected. At the annual meeting of our Board of

Item 1A—Risk Factors

We have a history of losses and may experience losses in the future.

Our prospects must be considered in light of the risks, expenses, delays and difficulties frequently encountered by companies engaged in rapidly evolving technology markets like ours. We incurred net losses of $3.9 million, $7.5 million, and $9.2 million in 2005, 2004, and 2003, respectively. As of December 31, 2005, we had incurred cumulative net losses of $290.7 million.

Our success may depend in large part upon the adoption and utilization of our products and technology, as well as our ability to effectively maintain existing relationships and develop new relationships with customers and strategic partners. If we do not succeed in doing so, we may not achieve or maintain profitability on a timely basis or at all. In particular, we intend to expend significant financial and management resources on product development, sales and marketing, strategic relationships, technology, and operating infrastructure. As a result, we may incur additional losses for the foreseeable future and may not achieve or maintain profitability.

If we do not develop our products, marketing, sales execution, and distribution channels more successfully than our competitors, our business could be harmed.

If we do not optimize our methods of producing, marketing and selling our products, it could significantly limit our ability to compete successfully against current and future competitors. The markets in which we compete are intensely competitive and rapidly changing, in part because third parties (such as hackers and spammers) whose timing and methods are somewhat unpredictable can have a significant impact on customer demand. Vendors in our markets use different methods of marketing and distribution in order to meet expected customer demand. For example, our competitors in the anti-spam market include multiple software-only vendors, appliance-only vendors, and service providers, as well as vendors that offer a combination of some or all of the foregoing. Moreover, vendors’ offerings range from single-function point products and services to more sophisticated and scalable multi-functional offerings. In addition, pricing and other terms and conditions of sales contracts also vary considerably among our competition. Because it is difficult to predict demand in our rapidly changing markets, we may not be able to manage our marketing and sales efforts in an optimal way, which may disadvantage our business in comparison to competitors.

Additional competitive factors in our industry include customer-driven requirements such as additional functionality, improved product performance, ease of use, integration capacity, platform coverage, and the quality of each vendor’s global technical support. Some of our competitors have greater financial, technical, sales, marketing and other resources than we do, as well as greater name recognition and a larger installed customer base. Additionally, some of these competitors have research and development capabilities that may allow them to develop new or improved products that may compete with product lines we market and distribute.

We expect that the market for email and data security products will become more consolidated with larger companies being better positioned to compete in such an environment in the long term. As this market continues to develop, a number of companies with greater resources than ours could attempt to increase their presence in this market by acquiring or forming strategic alliances with our competitors or business partners.

Our success will depend in part on our ability to adapt to these competing forces, to develop more effective products more rapidly and less expensively than our competitors, and to educate potential customers as to the benefits of licensing our products rather than developing their own products. Competitors could introduce products with superior features, scalability and functionality at lower prices than our products and could also bundle existing or new products with other more established products in order to compete with us. In addition, because there are relatively low barriers to entry for the software market, we expect additional competition from other established and emerging companies. Increased competition is likely to result in price reductions, reduced gross margins and loss of market share, any of which could harm our business.

In addition, our success depends in part on our ability to grow and develop our indirect distribution channels, in both North and South America as well as in Asia and Europe, and the inability to do so could adversely affect future operating results. Our failure to increase revenue through our indirect distribution channels, particularly overseas, could have a material adverse effect on our business, operating results, and financial condition. We must increase the number of strategic and other third-party relationships with vendors of Internet-related systems and application software, resellers and systems integrators. Our existing or future channel partners may choose to devote greater resources to marketing and supporting the products of other companies.

The volume of spam may not continue to grow rapidly, which may adversely affect the market for anti-spam solutions.

Although the volume of spam has grown rapidly during the last several years, it may not continue to do so because of recently enacted anti-spam legislation, enforcement efforts under that legislation, and collaborative efforts by leaders of the email provider industry, as well as the potential development of new and successful anti-spam technologies. Accordingly, the market for anti-spam solutions may not continue to grow rapidly and may in fact decline, which may adversely affect our business.

Contractual or other issues may arise during the negotiation of license agreements that may delay the anticipated closure of a transaction and our ability to recognize revenue as anticipated.

Because we focus on selling enterprise-wide software products to enterprises and government entities, the process of contractual negotiation is critical and may be lengthy. Additionally, many factors may require us to defer recognition of license revenue for a significant period of time after entering into a license agreement.

Many customers negotiate software licenses near the end of each quarter. In part, this is because customers are able, or believe that they are able, to negotiate lower prices and more favorable terms at that time. Our reliance on a large portion of software license revenue occurring at the end of the quarter and the increase in the dollar value of transactions that occur at the end of a quarter can result in increased uncertainty relating to quarterly revenues. Due to end-of-period variances, forecasts may not be achieved, either because expected sales do not occur or because they occur at lower prices or on terms that are less favorable to us.

Table of Contents

A limited number of customers account for a high percentage of our revenue, and the failure to maintain or expand these relationships could adversely affect our future revenue.

The loss of one or more of our major customers, the failure to attract new customers on a timely basis or a reduction in revenue associated with existing or proposed customers would harm our future revenue and prospects. For 2005, 2004, and 2003, five customers comprised approximately 11%, 12%, and 16%, respectively, of our revenue. For 2005, 2004 and 2003, respectively, no single customer comprised 10% or more of our revenue.

Fluctuations in our quarterly operating results may not be predictable and may result in significant volatility in our stock price.

Our revenue has fluctuated and our quarterly operating results may continue to fluctuate based on, among other things, the timing of the execution and termination of customer agreements in a given quarter. We have experienced, and expect to continue to experience, fluctuations in revenue and operating results from quarter to quarter for other reasons, including the timing of our target customers’ election to adopt and implement our technology, election of our customers to delay their purchase commitments or purchase in smaller amounts, and timing and ability to continue to license our patents. Further, we have experienced and may continue to experience difficulty in managing the amount and timing of operating costs and capital expenditures relating to our business, operations and infrastructure as well as collecting fees owed by customers. Finally, any acquisitions or divestitures we complete as well as the announcement or introduction of new or enhanced products and services in the secure content management, content security, secure online communications, or document delivery markets may create additional volatility in our results.

As a result of these factors, we believe that quarter-to-quarter comparisons of our revenue and operating results are not necessarily meaningful, and that these comparisons may not be accurate indicators of future performance. We may not be able to accurately forecast our revenue or expenses. Because our staffing and operating expenses are based on anticipated revenue levels, and because a high percentage of our costs are fixed, small variations in the timing of the recognition of specific revenue could cause significant variations in operating results from quarter to quarter. In addition, many of our customers delay purchases of our products until the end of each quarter. If we are unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall, any significant revenue shortfall would likely have an immediate negative effect on our operating results. Moreover, we believe the challenges and difficulties that we face, as outlined above with respect to financial forecasts, also apply to securities analysts that may publish estimates of our financial results. Our operating results in the past have, and in future quarters may, fail to meet our expectations or those of securities analysts or our investors due to any of a wide variety of factors, including fluctuations in financial ratios or other metrics used to measure our performance. If this occurs, we would expect to experience an immediate and significant decline in the trading price of our stock.

Economic conditions that result in a decrease in information technology spending could adversely affect our ability to maintain and increase revenue.

Our revenue and profitability or loss depends on the overall demand for our products, our intellectual property, and our services, particularly within the industries in which we offer specific versions of our products. Because our sales are primarily to customers in the financial services, health care, and government industries, our business depends on the overall economic conditions and the economic and business conditions within these industries. Any weakening of the global economy, the information technology industry in particular, and the weakening of the business conditions within the above industries could cause a decrease in our revenues. A softening of demand for information technology spending caused by a weakening of the economy, domestically or internationally, could result in a decrease in revenues and continued losses.

We expect to continue making strategic investments and acquisitions and potentially divest assets, which may involve substantial costs, may substantially dilute our existing investors, and may fail to yield anticipated benefits.

We are continuously evaluating investments in complementary technologies and businesses as well as strategic divestments. Acquisitions of companies, divisions of companies, or products, including our acquisitions of Incubator and Corvigo, as well as divestitures, entail numerous risks, including:

 

    potential inability to successfully integrate acquired operations, technologies, people in dispersed geographic areas and products or to realize cost savings or other anticipated benefits from integration as well as the existence of potential unknown liabilities associated with acquired business;

 

    the inability to recognize revenue from target acquisitions in accordance with our expectations;

 

    diversion of management’s attention, disruption of ongoing business and impairment of relationships with employees and customers of either an acquired company or our business; and

 

    coordinating sales and pricing efforts to effectively communicate the value and capabilities of the combined company.

As a result of acquisitions, we may acquire significant assets that include goodwill and other purchased intangibles. The testing of these intangible assets under established accounting guidelines for impairment requires significant use of judgment and assumptions. Changes in business conditions could require adjustments to the valuation of these assets.

Our stock price could be adversely affected if we are unable to continue to favorably assess the effectiveness of our internal control over financial reporting or if our auditors are unable to provide an unqualified attestation report on our assessment.

In the future, we may encounter problems or delays in completing the implementation of any changes necessary to make a favorable assessment of our internal controls over financial reporting. In addition, in connection with the attestation process by our independent registered public accounting firm, we may encounter future problems or delays in completing the implementation of any requested improvements and receiving a favorable attestation. If we cannot favorably assess the effectiveness of our internal controls over financial reporting, investor confidence and our stock price could be adversely affected.

The terms of any financing we may obtain could result in substantial dilution of existing stockholders.

In the future, we may be required or elect to seek additional financing to fund our operations. Factors such as the commercial success of our existing products and services, the timing and success of any new products and services, the progress of our research and development efforts, our results of operations, the status of competitive products and services, and the timing and success of potential strategic alliances or potential opportunities to acquire or sell technologies or assets may require us to seek additional funding sooner than we expect. In the event that we require additional cash, we may not be able to secure additional financing on terms that are acceptable to us, especially in light of uncertainty in the current market environment, and we may not be successful in implementing or negotiating such other arrangements to improve our cash position. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders would be reduced and the securities we issue might have rights, preferences and privileges senior to those of our current stockholders. If adequate funds were not available on acceptable terms or at all, our ability to achieve or sustain positive cash flows, maintain current operations, fund any potential expansion, take advantage of new opportunities, develop or enhance products or services, or otherwise respond to competitive pressures could be significantly limited.

Our certificate of incorporation and bylaws contain provisions that could discourage or prevent an acquisition of us, which could depress our stock price.

Certain provisions of our certificate of incorporation and bylaws, as well as provisions of Delaware law, may discourage or prevent an acquisition or disposition of our business. Our certificate of incorporation and bylaws may inhibit changes of control that are not approved by our Board of Directors. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. In particular, our certificate of incorporation includes provisions for a classified Board of Directors and prohibits stockholder action by written consent. Further, our bylaws contain provisions requiring advance notice for nomination of directors and stockholders’ proposals. In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. In general, this law prevents a person who becomes the owner of 15% or more of the corporation’s outstanding voting stock from engaging in specified business combinations for three years unless specified conditions are satisfied. In addition, our certificate of incorporation allows our Board of Directors to issue preferred stock without further stockholder approval. The issuance of preferred stock also could effectively limit the voting power of the holders of our common stock. This could have the effect of delaying, deferring or preventing a change in control.

We may be unable to adequately protect our intellectual property rights or may be subject to claims of patent infringement, either of which could result in substantial costs to us.

We currently rely on a combination of patents, trade secrets, copyrights, trademarks and licenses, together with non-disclosure and confidentiality agreements, to establish and protect our proprietary rights in our products. We hold certain patent rights with respect to some of our products. Our existing patents or trademarks, as well as any future patents or trademarks obtained by us, may be challenged, invalidated or circumvented, or our competitors may independently develop or patent technologies that are substantially equivalent or superior to our technology. We also rely on unpatented trade secrets and other unpatented proprietary information. Although we take precautionary measures to maintain our unpatented proprietary information, others may acquire equivalent information or otherwise gain access to or disclose our proprietary information, and we may be unable to meaningfully protect our rights to our proprietary information. As a result, our operating results could suffer.

Third parties could assert patent or other intellectual property infringement claims against us and the cost of responding to such assertions, regardless of their validity, could be significant. We may increasingly be subject to claims of intellectual property infringement as the number of our competitors grows and the functionality of their products and services increasingly overlap with ours. In addition, we may infringe upon patents that may be issued to third parties in the future. It may be time consuming and costly to defend ourselves against any of these claims and we may not prevail. Furthermore, parties making such claims may be able to obtain injunctive or other equitable relief that could block our ability to further develop or commercialize some or all of our products in the United States and abroad. In the event of a claim of infringement, we may be required to obtain one or more licenses from or pay royalties to third parties. We may be unable to obtain any such licenses at a reasonable cost, if at all. Defense of any lawsuit or failure to obtain such license could harm our business.

The enforcement of our intellectual property rights, especially through patent infringement lawsuits we may initiate, could result in substantial litigation costs and ultimately may not result in additional revenue to us or a favorable judicial determination.

Since 1999 we have aggressively pursued cases of potential infringement by third parties of our patents and other intellectual property rights. The enforcement process is costly and requires significant management attention. These costs are expensed during the period incurred, and the costs of pursuing the litigation may not be directly matched with the related patent license agreement revenue, if any. In addition, our enforcement of our rights may increase the risk of adverse claims, with or without merit, which could be time consuming to defend, result in costly litigation, divert management’s attention and resources, limit the use of our services, or require us to enter into royalty or license agreements. In addition, such counter-claims asserted by these third parties may be found to be valid and could result in an injunction or damages against us. Our ability to prevail in this litigation is

inherently uncertain, and if we were subject to an adverse judicial determination, our ability to protect our products and to secure related licensing or settlement revenue could be lost.

Failure to license necessary third party software incorporated in our products could cause delays or reductions in our sales.

We license third party software that we incorporate into our products. These licenses may not continue to be available on commercially reasonable terms, or at all. Some of this technology would be difficult to replace. The loss of any such licenses could result in delays or reductions of our applications until we identify, license and integrate or develop equivalent software. If we are required to enter into license agreements with third parties for replacement technology, we could face higher royalty payments and our products may lose certain attributes or features. In the future, we might need to license other software to enhance our products and meet evolving customer needs. If we are unable to do this, we could experience reduced demand for our products.

Our new products may not be adopted in the market and our appliance products may expose us to hardware supply chain issues.

From time to time we introduce new products, which may not be adopted readily or widely in the marketplace. If so, our business could be harmed. In addition, as a result of the product and technology acquired in the Corvigo acquisition in 2004, we have seen an increase in sales of our products sold as hardware appliances, which are manufactured by a third party. The inclusion of these hardware appliances in our product portfolio subjects us to additional risks, including, but not limited to:

 

    the inability of the manufacturer to perform in accordance with our expectations;

 

    the inability to deliver appliance products to customers in a timely manner, harming our ability to win time-sensitive customer contracts and/or recognize revenue;

 

    product shortages that could result in increased product costs;

 

    price increases from suppliers that may not be able to be passed on to customers;

 

    oversupply or obsolescence of inventory, which may result in the need to reduce our prices and/or write down inventory; and

 

    product quality issues.

The occurrence of any of these events could adversely affect our business and operating results.

We are a defendant in two purported securities class action lawsuits that could divert management attention and resources or eventually expose us to liability.

In June 2003, we were served with a summons and first amended complaint, captioned Liu v. Credit Suisse First Boston, et alia, alleging the violation of federal and state securities laws, purportedly on behalf of persons who acquired our common stock of (other than purchasers of our initial public offering) from August 6, 1999 to October 18, 2000. The case was transferred to the United States District Court for the Southern District of New York, where in March 2005, the Court dismissed the case with prejudice. In June 2005 plaintiffs filed an appeal of the dismissal with the United States Court of Appeals for the Second Circuit, which remains pending. An adverse outcome in this case could harm our business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as we do not consider a loss to be probable at this time.

In December 2001, certain plaintiffs filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of Valicert, alleging violations of federal securities laws. In re Valicert, Inc. Initial Public Offering Securities Litigation, No. 01-CV-10889 (SAS)

Table of Contents

(S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). In June 2003, Valicert accepted a settlement proposal presented to all issuer defendants in this case. Under the proposed settlement, the plaintiffs will dismiss and release all claims against the Valicert Defendants in exchange for a contingent payment guaranty by the insurance companies collectively responsible for insuring the issuers in all the consolidated cases, and the assignment or surrender of control to the plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the guaranty, the insurers will be required to pay the amount, if any, by which $1 billion exceeds the aggregate amount ultimately collected by the plaintiffs from the underwriter defendants in all of the cases. If the plaintiffs fail to recover $1 billion and payment is required under the guaranty, Valicert would be responsible to pay its pro rata portion of the shortfall, up to the amount of the deductible retention under its insurance policy, which is $500,000. The timing and amount of payments that Valicert could be required to make under the proposed settlement will depend on several factors, principally the timing and amount of any payment required by the insurers pursuant to the $1 billion guaranty. The proposed settlement is subject to approval of the Court, which cannot be assured. Failure of the Court to approve the settlement followed by an adverse outcome could harm our business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as we do not consider a loss to be probable at this time.

If we lose the services of executive officers or other key employees, our ability to develop our business and secure customer relationships will suffer.

We are substantially dependent on the continued services and performance of our executive officers and other key personnel and do not have long-term employment agreements with any of our key personnel. In this regard, we recently appointed a new Chief Executive Officer, which subjects us to heightened risks related to this transition as he assumes this role and makes changes to our business and operations. The loss of the services of any of our executive officers or other key employees could significantly delay or prevent the achievement of our development and strategic objectives.

Our international business exposes us to additional risks that may result in future additional costs or limit the market for product sales.

Products and services provided to our international customers accounted for 10%, 11%, and 5% of our revenues for 2005, 2004, and 2003, respectively. Conducting business outside of the United States subjects us to additional risks, including:

 

    changes in regulatory requirements;

 

    reduced protection of intellectual property rights; evolving privacy laws; tariffs and other trade barriers;

 

    difficulties in staffing and managing foreign operations;

 

    problems in collecting accounts receivable; and

 

    difficulties in authenticating customer information.

Managing these risks may subject us to additional costs that may not be justified in light of the market opportunity, and the inability to comply with or manage foreign laws and related risks may preclude or limit sales in foreign jurisdictions.

We rely on public key cryptography and other security techniques that could be breached, resulting in reduced demand for our products and services.

A requirement for the continued growth of electronic commerce is the secure transmission of confidential information over public networks. We rely on public key cryptography, an encryption method that utilizes two keys, a public and private key, for encoding and decoding data, and on digital certificate technology, to provide

Table of Contents

the security and authentication necessary for secure transmission of confidential information. Regulatory and export restrictions may prohibit us from using the strongest and most secure cryptographic protection available, and thereby may expose us or our customers to a risk of data interception. A party who is able to circumvent our security measures could misappropriate proprietary information or interrupt our or our customers’ operations. Any compromise or elimination of our security could result in risk of loss or litigation and possible liability and reduce demand for our products and services.

Item 1B—Unresolved Staff Comments

Not applicable.

Item 2—Properties

In 1999, we entered into an operating lease covering approximately 40,000 square feet of office space in Redwood City, California and renewed that lease in 2003. The renewed lease expires in July 2008 with current monthly rent payments of approximately $73,000.

We also maintain sales offices in Hurst, United Kingdom with a lease term expiring in 2008; McLean, Virginia with a lease term expiring in 2006; New York, New York with a lease term expiring in 2006; Singapore with a lease term expiring in 2006; and Oakbrook Terrace, Illinois with a lease term expiring in 2006. Other offices we maintain include Palo Alto, California, Pfaffikon, Switzerland, and Sofia, Bulgaria. The Palo Alto, Pfaffikon, and Sofia leases have terms expiring in 2007, 2006, and 2007, respectively. The Palo Alto lease was subleased in December 2004 for the remainder of the lease term with sublease rental income less than our rent payments due to a weak office rental market in and around Palo Alto.

Other than our office space in Redwood City, California, and Sofia, Bulgaria, none of our offices individually exceed 12,000 square feet in size. Other than the facility space that we have subleased as described above and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, we are currently utilizing all of our leased facility space. We believe our current facilities will be adequate to meet our needs for the foreseeable future.

Item 3—Legal Proceedings

In December 2001, certain plaintiffs filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of Valicert, alleging violations of federal securities laws. In re Valicert, Inc. Initial Public Offering Securities Litigation, No. 01-CV-10889 (SAS) (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). The operative amended complaint is brought on purported behalf of all persons who purchased Valicert common stock from the date of its July 27, 2000 initial public offering (“IPO”) through December 6, 2000. It names as defendants Valicert, its former Chief Executive Officer, its Chief Financial Officer (the “Valicert Defendants”), as well as an investment banking firm that served as an underwriter for the IPO. The complaint alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriter agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to the paid to the underwriter; and (2) the underwriter arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of damages. Similar allegations have been made in lawsuits relating to more than 300 other initial public offerings conducted in 1999 and 2000, all of which have been consolidated for pretrial purposes. In February 2003, the Court issued a ruling on all defendants’ motions to dismiss, denying Valicert’s motion to dismiss the claims under the Securities Act of 1933, but granting Valicert’s motion to dismiss the claims under the Securities Exchange Act of 1934.

We indemnify our customers from third party claims of intellectual property infringement relating to the use of our products. Historically, costs related to these guarantees have not been significant and we are unable to estimate the potential impact of these guarantees on our future results of operations.

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

The following discussion should be read in conjunction with the consolidated financial statements and notes included elsewhere in this report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and those listed under “Risk factors.”

Overview

Tumbleweed Communications Corp. (“Tumbleweed” or “we”) is a recognized expert in providing secure Internet communication solutions for enterprise and government customers of all sizes. With our products, organizations can block security threats, protect information, safely conduct business online, and reduce their cost of doing business. Our industry-leading secure Internet communications product suites – MailGate, SecureTransport, and Validation Authority – provide solutions for Dynamic Anti-spam Service, content filtering, email encryption, multi-protocol file transfer and comprehensive identity validation.

We are trusted by approximately 1,600 enterprise and government customers who use our products to connect with over ten thousand corporations and millions of end-users. Our market focus is in the financial services, healthcare, and government segments. Our security software and appliances provide comprehensive, modular solutions for email, file transfer and identity validation applications. Using products from our secure Internet communications portfolio, organizations can more safely and reliably conduct business over the internet.

Our operating results during 2005 showed improvement relative to 2004 in revenue, deferred revenue, net loss, and operating cash flow. Our 15% growth in revenue and 26% growth in deferred revenue were driven by a number of factors including increased revenue from our Mailgate, SecureTransport, and Validation Authority products, an increase in patent license revenue, and revenue growth in our targeted customer sectors in the financial services, health care, and government industries. Our reduction in net loss of 48% was due to our growth in revenues and our continuing focus on generating cost efficiencies including our development center in Bulgaria, which has allowed us to augment our research and development and services offerings at a relatively lower cost structure. In addition, our cash flow from operations increased to $4.7 million from $433,000 in 2004, primarily due to our reduction in net loss.

Outlook

We believe that our success in 2006 will depend on our ability to increase customer adoption of our products; our ability to successfully expand our sales internationally and through distribution by third party resellers; our ability to further implement the processes related to selling hardware appliance products, such as supply chain effectiveness; and our ability to maintain control over expenses and cash. We believe that key risks include overall economic conditions and the overall level of information technology spending; economic and business conditions within our target customer sectors in the financial services, health care, and government industries; timing of the closure of customer contracts; growing our sales internationally; the integration of our new Chief Executive Officer, and competitive factors in our rapidly changing industry. Our prospects must be considered in light of the risks, expenses and difficulties encountered by companies at an early stage of development, particularly given that we operate in rapidly evolving markets, have completed several acquisitions and face an uncertain economic environment. We may not be successful in addressing such risks and difficulties. Please refer to the “Risk Factors” section for additional information.

Recent Events

In January 2006, our Board of Directors named James P. Scullion as Chief Executive Officer and Chairman of the Board of Directors. Mr. Scullion replaced Craig D. Brennan who had served as Chief Executive Officer and Chairman of the Board of Directors since June 30, 2005. Mr. Brennan resigned from these positions in

On March 18, 2004, we completed the acquisition of Corvigo, Inc. (“Corvigo”), an anti-spam appliance vendor. The purchase price of $40.9 million consisted of an exchange of 4,732,284 shares of Tumbleweed’s common stock with a fair value of $32.8 million based on the fair value of our common stock on the date of the acquisition, cash paid of $6.0 million, assumed stock options with a fair value of $1.3 million, severances for former Corvigo employees of $97,000, and other acquisition-related costs of $727,000, consisting primarily of legal fees, banking fees, and accounting fees.

On March 15, 2004, we completed the acquisition of Incubator, Limited (“Incubator”), a reseller of our products. The acquisition was entered into to expand our sales in Europe. The purchase price of $1.7 million consisted of an exchange of 224,278 shares of our common stock with a fair value of $1.6 million based on the fair value of our common stock on the date of the acquisition and other acquisition-related costs of $119,000 consisting of legal and accounting fees.

Revenue. Revenue, which consists of product revenue, service revenue and intellectual property and other revenue, results from new contracts and backlog. We define backlog as deferred revenue, contractual commitments that are not due and payable as of the balance sheet date, or for which collectibility is in doubt, and/or for which the product or service has not yet been delivered. Product revenue consists of license fees,

Table of Contents

subscription-based license fees, and transaction-based license fees. Service revenue includes support and maintenance fees, consulting fees, and training fees. Intellectual property and other revenue consists of patent license agreement fees and the sale of distribution rights. Total revenue increased to $50.0 million in 2005 from $43.4 million in 2004. The increase in total revenue was primarily due to a $1.3 million increase in product revenue, a $4.2 million increase in support and maintenance revenue, and a $1.1 million increase in patent license revenue.

Product revenue increased to $20.9 million in 2005 from $19.6 million in 2004. The increase in product revenue was due to an increase in license revenue of $1.8 million, partially offset by decreases in subscription-based license revenue and transaction-based license revenue of $290,000 and $182,000, respectively. The increase in license revenue was primarily due to an increased volume of license contracts resulting from an increase in new customers as well as an increase in contracts with existing customers. The decreases in subscription-based license revenue and transaction-based license revenue were due to our continued transition away from those selling models and towards selling perpetual licenses with associated support and maintenance contracts.

Service revenue increased to $26.1 million in 2005 from $21.9 million in 2004. The increase in service revenue was primarily due to a $3.5 million increase in support and maintenance revenue and a $493,000 increase in consulting revenue. The increase in support and maintenance revenue was due to revenue growth in our installed customer base, an increase in sales of our Dynamic Anti-spam Service, which is sold on a subscription fee basis, and an expansion of our customer base. The increase in consulting revenue was due to increased consulting opportunities due to the expansion of our customer base and repeat business with existing customers for development projects.

Intellectual property and other revenue increased to $3.0 million in 2005 from $1.9 million in 2004. The increase in intellectual property and other revenue was due to an increase in patent license revenue.

Cost of Revenue. Cost of revenue is comprised of product costs, service costs, and the amortization of intangible assets for core/developed technology and maintenance agreements relating to the acquisitions of Valicert, Incubator, and Corvigo. Product costs are primarily comprised of royalties paid to third parties for software licensed by us for inclusion in our products, the cost of our appliance products, and employee and employee-related costs for hardware operations. Service costs are comprised primarily of employee and employee-related costs for customer support, consulting and training, and contract development projects with third parties. Total cost of revenue increased to $10.4 million in 2005 from $7.9 million in 2004, primarily due to a $1.3 million increase is service costs and a $949,000 increase in product costs.

Cost of product revenue increased to $2.9 million in 2005 from $2.0 million in 2004 due primarily to an increase in appliance costs, royalty costs, and employee and employee-related costs for hardware operations. Appliance costs increased by $228,000 during 2005 due to an increase in sales of our appliance products and an expense for obsolete inventory associated with our transition to a new appliance manufacturer. Royalty costs increased by $583,000 during 2005 primarily due to the addition of new software licenses from third parties included in our products. Employee and employee-related costs for hardware operations increased by $129,000 due to the addition of headcount to support supply chain efforts related to our appliance products.

Cost of service revenue increased to $5.4 million in 2005 from $4.1 million in 2004, primarily due to an increase in employee and employee-related costs. Employee and employee-related costs increased by $1.1 million during 2005 due to an increase in average services headcount to 48 employees in 2005 from 39 employees in 2004. The increase in average services headcount was primarily due to the need for greater personnel resources to fulfill the requirements for our increased service revenues. We expect cost of service revenue to increase during 2006 due to an anticipated increase in employee and employee-related costs due to increased headcount required to meet our customer requirements.

Amortization of intangible assets included in cost of revenue increased to $2.0 million in 2005 from $1.8 million in 2004 due to the acquisitions of Corvigo and Incubator in March of 2004 since there was a full twelve months of amortization during 2005 compared to less than ten full months of amortization recognized during 2004.

Research and Development Expenses. Research and development expenses are primarily comprised of employee and employee-related costs and other costs required for the development and quality assurance of our products. Research and development expenses increased to $11.9 million in 2005 from $11.6 million in 2004, primarily due to an $861,000 increase in employee and employee-related costs, partially offset by a $716,000 decrease in allocated overhead charges. Employee and employee-related costs increased primarily due to salary increases and growth in average engineering headcount to 149 employees in 2005 from 135 employees in 2004. The increase in average engineering headcount was driven by our efforts to broaden and upgrade our products. Allocated overhead charges decreased due to a decrease in our allocable cost base caused by lower information technology and facility costs. We expect research and development expenses to increase during 2006 due to an anticipated increase in headcount largely due to a realignment of resources into our research and development function from other functions during 2006.

Sales and Marketing Expenses. Sales and marketing expenses are primarily comprised of employee and employee-related costs associated with the selling and marketing of our products, travel expenses, and costs associated with marketing programs. Sales and marketing expenses increased to $25.0 million in 2005 from $23.1 million in 2004 primarily due to a $785,000 increase in employee and employee-related costs, a $417,000 increase in marketing programs, and a $123,000 increase in consulting costs. In addition, sales and marketing expenses increased due to new expenses of $295,000 associated with the expansion of our sales team in Asia during the second half of 2005. Employee and employee-related costs increased due to increased commissions as a result of increased sales in 2005. Consulting costs increased due to the increased usage of third parties to assist our sales and marketing employees. Marketing programs increased due to an increase in marketing initiatives targeted at growing our revenues. We expect sales and marketing expenses to increase during 2006 due to an anticipated increase in headcount to further expand our sales presence and an anticipated increase in marketing programs.

General and Administrative Expenses. General and administrative expenses consist primarily of employee and employee-related and support costs for our administrative, finance, legal, and human resources departments as well as public reporting costs, and professional fees including intellectual property enforcement and protection costs. General and administrative expenses increased to $5.9 million in 2005 from $5.3 million in 2004. The increase in general and administrative expenses was primarily due to a $247,000 increase in recruiting expenses, a $161,000 increase in commissions, and a $74,000 increase in expensed equipment and software. Recruiting expenses increased due to the utilization of third-parties to assist in our hiring processes, including the recruitment of our former Chief Executive Officer, with little comparable expenses for 2004. Commissions increased due to an increase in patent license revenue for 2005. Expensed equipment and software increased due to a higher usage driven by an increased number of employees.

Stock-based compensation expense. Stock-based compensation expense consists of the amortization of deferred stock-based compensation recorded as a result of stock option grants to non-employees, unvested options assumed in the Valicert and Corvigo acquisitions, options granted to employees at exercise prices less than the fair value of the underlying stock on the grant date, continued vesting of stock options for a former employee after the end of their service period, and the vesting acceleration of certain employees’ stock options, net of credits related to stock options granted to employees who were later terminated before the options vested. Stock-based compensation expense decreased to $510,000 in 2005 from $640,000 in 2004. The decrease in stock-based compensation expense was primarily due to reductions in the amortization of deferred stock-based compensation resulting from unvested options assumed in the Valicert and Corvigo acquisitions.

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS 123 (revised 2004), Share-Based Payment (“SFAS 123R”), which revises SFAS 123, Accounting for Stock-Based Compensation

Table of Contents

(“SFAS 123”) and supercedes Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees. SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values, effective at the beginning of the next fiscal year that starts after June 15, 2005. We will adopt SFAS 123R in the first quarter of 2006, beginning January 1, 2006. The pro forma disclosures previously permitted under SFAS 123 will no longer be an alternative to financial statement recognition. Under SFAS 123R, we must determine the appropriate fair value model to be used for valuing share-based payments, the amortization method for compensation cost and the transition method to be used at date of adoption. The transition methods include prospective and retroactive adoption options. Under the retroactive options, prior periods may be restated either as of the beginning of the year of adoption or for all periods presented. The prospective method requires that compensation expense be recorded for all unvested stock options and restricted stock at the beginning of the first quarter of adoption of SFAS 123R, while the retroactive methods would record compensation expense for all unvested stock options and restricted stock beginning with the first period restated. We are evaluating the requirements of SFAS 123R and we expect that the adoption of SFAS 123R will have a material adverse impact on our consolidated results of operations and earnings per share. We have not yet determined the method of adoption or the effect of adopting SFAS 123R, and we have not determined whether the adoption will result in amounts that are similar to the current pro forma disclosures under SFAS 123 included in the Notes to Consolidated Financial Statements.

On July 19, 2005, our Board of Directors approved the acceleration of vesting of certain unvested stock options with exercise prices equal to or greater than $3.82 per share previously awarded to our employees (including our executive officers) and our directors under the our stock option plans. The acceleration of vesting was effective for stock options outstanding as of July 19, 2005. Options to purchase approximately 1.7 million shares of common stock were accelerated. All of the options accelerated had exercise prices greater than our common stock price of $3.24 on the date of acceleration. The weighted average exercise price of the options accelerated was $5.00. The purpose of the acceleration was to enable us to avoid recognizing compensation expense associated with these options in future periods in our consolidated statement of operations, upon adoption of SFAS 123R.

Amortization of intangible assets. Amortization of intangible assets included in operating expenses consists of the amortization of intangible assets for customer base and reseller agreements and trademarks and tradenames recorded as a result of the Valicert, Incubator, and Corvigo acquisitions, and the conversion of certain former contract engineers to employees in our offshore development center in Bulgaria. Amortization of intangible assets included in operating expenses decreased to $1.3 million in 2005 from $1.5 million in 2004. The decrease in the amortization of intangible assets included in operating expenses was due to the amortization in full during 2004 of the acquired workforce asset, partially offset by a full twelve months of amortization of the intangible assets acquired in the acquisitions of Incubator and Corvigo, during 2005, compared to less than ten full months of amortization recognized during 2004.

Merger-related and other costs. Merger-related and other costs of a net credit of $96,000 for 2005 consist of a $296,000 credit related to the termination of an operating lease in Slough, United Kingdom and a $200,000 severance cost associated with the resignation of our former Chief Executive Officer. The combined cost of the final lease settlement payments, commissions, brokerage fees, and legal fees related to the termination of the Slough lease was less than the existing accrual for the loss on the lease, resulting in the expense credit.

Merger-related and other costs of $1.1 million for 2004 consist of $703,000 of severance costs for Tumbleweed employees terminated in connection with the Corvigo acquisition and the sale of our offshore development subsidiary in India to a third party, $183,000 related to anticipated losses on an operating lease in Palo Alto, California, $168,000 related to anticipated losses on an operating lease in Slough, United Kingdom, a credit of $44,000 for a gain on the sale of our offshore development center subsidiary in India, and $68,000 of other merger-related costs. The operating lease in Palo Alto was assumed during the acquisition of Corvigo and covers approximately 12,000 square feet of office space. Subsequent to the acquisition of Corvigo, we decided to vacate the Palo Alto facility. The lease is for a term ending in 2007 with current monthly rent payments of

Table of Contents

approximately $22,000. The $183,000 charge was recorded due to a revised estimate of the period required to locate and contract with a sublessee and reduced sublease rates. As a result of the new estimate, the existing accrual for the loss on the lease was found to be insufficient and the remaining balance for that liability was reclassified on our consolidated balance sheet from accrued liabilities to accrued merger-related and other costs to be tracked along with the liability resulting from the revised estimate recorded in the three months ending September 30, 2004. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than our rent payments due to a weak office rental market in and around Palo Alto. The operating lease in Slough was assumed during the acquisition of Interface, Inc. in 2000 and covered approximately 13,000 square feet of office space. The lease was for a term ending in 2020 with quarterly rent payments of approximately $65,000. The $168,000 charge was recorded due to a revised estimate of the term of expected subleases on the building. Our offshore development center subsidiary in India was acquired in the acquisition of Valicert and supported our engineering, customer support, and consulting functions. This subsidiary was sold to consolidate our offshore development in our existing Bulgaria location.

Other income, net. Other income, net, is generally comprised of interest income earned on investment securities and interest expense incurred on outstanding debt. Other income, net, increased to $982,000 in 2005 from $213,000 in 2004. The increase in other income, net was partially due to an increase in interest income of $385,000 in 2005 as a result of an increase in interest rates and a larger cash balance. In addition, during 2005, income of $204,000 was recorded for the refund of previously paid value added tax related to a Valicert subsidiary. No comparable income occurred during 2004. Finally, other income increased by $138,000 due to increases in amounts collected from current and former employees of acquired companies that were previously deemed uncollectible.

Years ended December 31, 2004 and 2003

Revenue. Total revenue increased to $43.4 million in 2004 from $30.6 million in 2003. The increase in total revenue was primarily due to a $9.3 million increase in service revenue and a $3.3 million increase in product revenue.

Product revenue increased to $19.6 million in 2004 from $16.3 million in 2003. The increase in product revenue was due to a $3.2 million increase in license revenue. License revenue increased primarily due to increased sales of the SecureTransport product acquired in the Valicert acquisition and increased customer adoption of our email firewall products. We also recognized revenue in 2004 from the anti-spam appliance product acquired in the Corvigo acquisition with no comparable revenue in 2003.

Service revenue increased to $21.9 million in 2004 from $12.6 million in 2003. The increase in service revenue was primarily due to an $8.5 million increase in support and maintenance revenue and a $800,000 increase in consulting revenue. Support and maintenance revenue increased due to revenue growth in our installed customer base, an increase in sales to new customers, an increase in sales of our Dynamic Anti-spam Service which is sold on a subscription fee basis, and an expansion of our customer base due to the Valicert and Corvigo acquisitions. Consulting revenue increased by $800,000 primarily due to the recognition of $672,000 of revenue as a result of a prepaid consulting contract that had an expiration clause requiring full revenue recognition in the three months ended March 31, 2004 for the portion of that contract that was in deferred revenue at December 31, 2003.

Intellectual property and other revenue increased to $1.9 million in 2004 from $1.6 million in 2003. The increase was due to an increase in patent license agreement revenue of $802,000, partially offset by $531,000 of revenue from the sale of distribution rights in 2003 with no comparable revenue in 2004.

Cost of Revenue. Total cost of revenue increased to $7.9 million in 2004 from $5.6 million in 2003 primarily due to a $1.1 million increase in the amortization of intangible assets service costs and a $1.0 million increase in product costs, mostly for appliance costs.

Table of Contents

Cost of product revenue increased to $2.0 million in 2004 from $959,000 in 2003 due primarily to an increase in hardware costs due to an increase in sales of our appliance products as a result of the product and technology acquired in the Corvigo acquisition. Cost of service revenue increased to $4.1 million in 2004 from $3.9 million in 2003, primarily due to an increase in average service employees to 39 in 2004 from 30 in 2003, with the majority of the increase in headcount coming from our development center in Bulgaria. Amortization of intangible assets increased to $1.8 million in 2004 from $750,000 in 2003 due to the acquisitions of Corvigo and Incubator in March of 2004 and the acquisition of Valicert in June of 2003.

Research and Development Expenses. Research and development expenses increased to $11.6 million in 2004 from $9.1 million in 2003, primarily due to a $2.4 million increase in employee and employee-related costs as a result of an increase in average engineering headcount to 135 employees in 2004 from 96 employees in 2003. The increase in average engineering headcount was driven by our efforts to broaden and upgrade our products including the addition of employees from the Valicert and Corvigo acquisitions.

Sales and Marketing Expenses. Sales and marketing expenses increased to $23.1 million in 2004 from $15.9 million in 2003 primarily due to a $4.7 million increase in employee and employee-related costs, a $1.4 million increase in marketing programs, a $632,000 increase in allocated overhead charges, and a $526,000 increase in travel costs. Employee and employee-related costs increased due to an increase in average sales and marketing headcount to 82 employees in 2004 from 55 employees in 2003 in order to expand our sales presence and increase our marketing programs to generate sales leads and increase awareness of our brand. Employee and employee-related costs also increased due to increased incentive compensation as a result of increased sales in 2004. Marketing programs increased due to an increase in marketing initiatives targeted at growing our revenues. Allocated overhead charges increased due to an increase in the proportion of U.S. sales and marketing headcount relative to total U.S. headcount. Travel expenses increased by $526,000 primarily due to the increase in the number of sales and marketing employees and the acquisition of Incubator which created a direct sales operation for us in Europe.

General and Administrative Expenses. General and administrative expenses decreased to $5.3 million in 2004 from $6.2 million in 2003. The decrease in general and administrative expenses was primarily due to a $1.0 million decrease in legal expenses and a $471,000 decrease in office expenses, partially offset by a $662,000 increase in audit and tax expenses. Legal expenses decreased primarily due to the settlement of a patent-related lawsuit in the fourth quarter of 2003 which reduced costs associated with this matter in 2004. Office expenses decreased primarily due to the renewal of our headquarters lease in the third quarter of 2003 where we received a lower monthly rent cost in exchange for an extension of the lease term. Audit and tax expenses increased during 2004 primarily due to costs for compliance with the Sarbanes-Oxley Act of 2002.

Stock-based compensation expense. Stock-based compensation expense increased to $640,000 in 2004 from $166,000 in 2003. The increase in stock-based compensation expense was due to the amortization of deferred stock-based compensation resulting from unvested options assumed in the Valicert and Corvigo acquisitions and grants of stock options to certain non-employees for professional services in 2004.

Amortization of intangible assets and write-off of in-process research and development. Amortization of intangible assets included in operating expenses increased to $1.5 million in 2004 from $532,000 in 2003. The increase in the amortization of intangible assets included in operating expenses was due to the acquisitions of Corvigo and Incubator in 2004 and the acquisition of Valicert in June of 2003 since there was no related amortization for the Corvigo and Incubator intangible assets in 2003 and no related amortization for the Valicert intangible assets for most of the first half of 2003. In-process research and development resulting from the Valicert acquisition was fully written off during 2003. No similar write-off was recorded in 2004.

Merger-related and other costs. Merger-related and other costs of $1.1 million for 2004 consist of $703,000 of severance costs for Tumbleweed employees terminated in connection with the Corvigo acquisition and the sale of our offshore development subsidiary in India to a third party, $183,000 related to anticipated

losses on an operating lease in Palo Alto, California, $168,000 related to anticipated losses on an operating lease in Slough, United Kingdom, a credit of $44,000 for a gain on the sale of our offshore development center subsidiary in India, and $68,000 of other merger-related costs. The operating lease in Palo Alto was assumed during the acquisition of Corvigo and covers approximately 12,000 square feet of office space. Subsequent to the acquisition of Corvigo, we decided to vacate the Palo Alto facility. The lease is for a term ending in 2007 with current monthly rent payments of approximately $22,000. The $183,000 charge was recorded due to a revised estimate of the period required to locate and contract with a sublessee and reduced sublease rates. As a result of the new estimate, the existing accrual for the loss on the lease was found to be insufficient and the remaining balance for that liability was reclassified on our consolidated balance sheet from Accrued liabilities to Accrued merger-related and other costs to be tracked along with the liability resulting from the revised estimate recorded in the three months ending September 30, 2004. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than our rent payments due to a weak office rental market in and around Palo Alto. The operating lease in Slough was assumed during the acquisition of Interface, Inc. in 2000 and covered approximately 13,000 square feet of office space. The lease was for a term ending in 2020 with quarterly rent payments of approximately $65,000. The $168,000 charge was recorded due to a revised estimate of the term of expected subleases on the building. Our offshore development center subsidiary in India was acquired in the acquisition of Valicert and supported our engineering, customer support, and consulting functions. This subsidiary was sold to consolidate our offshore development in our existing Bulgaria location.

Merger-related and other costs of $2.9 million for 2003 consist of $1.1 million of severance costs for Tumbleweed employees terminated in connection with the Valicert acquisition, $596,000 of merger-related marketing programs, $174,000 of other merger-related costs, and a $996,000 charge related to anticipated losses on the operating lease in Slough.

Other Income, Net. Other income, net, decreased to $213,000 in 2004 from $752,000 in 2003. The decrease in other income, net, was primarily due to a $527,000 gain on the sale in 2003, net of related commissions, of an intellectual property asset acquired during the acquisition of Valicert. No similar transaction occurred in 2004.

Liquidity and Capital Resources

Since inception, we have financed our operations primarily through the issuance of equity securities. As of December 31, 2005, we had approximately $27.0 million in cash and cash equivalents.

Net cash provided by operating activities increased to $4.7 million in 2005 from $433,000 in 2004. Net cash provided by operating activities in 2005 was primarily the result of our net loss of $3.9 million and adjustments to reconcile net loss to net cash provided by operating activities including an increase in deferred revenue of $4.8 million and non-cash charges for depreciation and amortization expenses of $4.5 million and stock-based compensation expense of $510,000, partially offset by an increase in our accounts receivable balance of $1.6 million. The increase in net cash provided by operating activities in 2005 relative to 2004 was primarily due to our reduction in net loss of $3.6 million.

Net cash used in investing activities decreased to $955,000 in 2005 from $4.8 million in 2004. Net cash used in investing activities in 2005 was comprised of purchases of property and equipment. Net cash used in investing activities in 2004 was comprised of $3.5 million for the acquisitions of Incubator and Corvigo, net of cash acquired, and $1.4 million for purchases of property and equipment. The decrease in net cash used in investing activities in 2005 relative to 2004 was primarily due to a $3.5 million outflow for the acquisitions of Incubator and Corvigo in 2004 with no comparable activity in 2005. The $3.5 million outflow for the acquisitions of Incubator and Corvigo includes the impact of a $6.0 million cash payment to Corvigo shareholders as part of the purchase price for Corvigo.

Table of Contents

Net cash provided by financing activities was $1.7 million in 2005 and $560,000 in 2004. Net cash provided by financing activities in 2005 was comprised of an inflow of $2.2 million for the proceeds from the issuance of common stock as a result of the exercises of stock options, partially offset by an outflow of $467,000 related to the full repayment of outstanding debt originally assumed in the acquisition of Valicert. Net cash provided by financing activities in 2004 was comprised of an inflow of $827,000 for the proceeds from the issuance of common stock as a result of the exercises of stock options and warrants, partially offset by an outflow of $267,000 related to repayments on outstanding debt originally assumed in the acquisition of Valicert. The increase in net cash provided by financing activities in 2005 relative to 2004 was primarily due to a $1.3 million increase in proceeds from the issuance of common stock in 2005 due to an increase in stock option exercises.

As of December 31, 2005, our principal commitments consisted of obligations related to outstanding operating leases and unconditional purchase obligations. We do not anticipate a substantial increase in operating lease obligations in the immediate future.

In June 1999, we entered into an operating lease covering approximately 40,000 square feet of office space in Redwood City, California and renewed that lease in 2003. The renewed lease expires in July 2008 with current monthly rent payments of approximately $73,000.

As a result of the Corvigo acquisition, we assumed an operating lease in Palo Alto, California. The lease is for a term ending in 2007 with current monthly rent payments of approximately $22,000. Subsequent to the acquisition of Corvigo, we decided to vacate the Palo Alto facility. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than our rent payments due to a weak office rental market in and around Palo Alto.

In the acquisition of Valicert, we assumed debt of $855,000 resulting from equipment leases with two financing companies. During 2003, this debt was refinanced with an $800,000 loan with a bank. This debt was repaid in full during 2005.

Our capital requirements depend on numerous factors, including revenue generated from operations and market acceptance of our products and services, and the resources devoted to the development of our products and services and to sales and marketing and other operating activities. We believe that our existing capital resources should enable us to maintain our current and planned operations for at least the next twelve months. Our current cash reserves, however, may be insufficient if we experience either lower than expected revenues or extraordinary or unexpected cash expenses, or for other reasons. Funding, if pursued, may not be available on acceptable terms or at all. If adequate funds are not available, we may be required to curtail significantly or defer one or more of our operating goals or programs, or take other steps that could harm our business or future operating results. We will continue to consider future financing alternatives, which may include the incurrence of debt, additional public or private equity offerings or an equity investment by a strategic partner; however, we have no present commitments or arrangements assuring us of any future equity or debt financing.

Off-Balance Sheet Arrangements

At December 31, 2005, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Recent Accounting Pronouncements

In May 2005, the FASB issued SFAS 154, Accounting Changes and Error Corrections – a replacement of APB Opinion No. 20 and FASB Statement No. 3 (“SFAS 154”). SFAS 154 requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change in nondiscretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the accounting change. SFAS 154 also requires that a change in depreciation, amortization, or depletion method for long-lived, nonfinancial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in fiscal years beginning after the date this Statement is issued. We will adopt the provisions of SFAS 154 in the first quarter of 2006, beginning January 1, 2006.

In March 2005, the SEC issued Staff Accounting Bulletin 107, Share-Based Payment (“SAB 107”) regarding the SEC’s interpretation of SFAS 123R. This interpretation expresses the views of the SEC regarding the interaction between SFAS 123R and certain SEC rules and regulations and provides the SEC’s views regarding the valuation of share-based payment arrangements for public companies. In particular, SAB 107 provides guidance related to share-based payment transactions with non-employees, the transition from nonpublic to public entity status, valuation methods, the accounting for certain redeemable financial instruments issued under share-based payment arrangements, the classification of compensation expense, non generally accepted accounting principles financial measures, first-time adoption of SFAS 123R in an interim period, capitalization of compensation cost related to share-based payment arrangements, the accounting for income tax effects of share-based payment arrangements upon adoption of SFAS 123R, the modification of employee share options prior to adoption of Statement 123R and disclosures in Management’s Discussion and Analysis subsequent to adoption of SFAS 123R. We will adopt SAB 107 in connection with our adoption of SFAS 123R in the first quarter of 2006, beginning January 1, 2006, which is expected to have a material adverse impact on our consolidated results of operations and earnings per share.

FASB Staff Position 109-2, Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004 (“FSP 109-2”), provides guidance under SFAS 109, Accounting for Income Taxes, with respect to recording the potential impact of the repatriation provisions of the American Jobs Creation Act of 2004 (the “Jobs Act”) on enterprises’ income tax expense and deferred tax liability. The Jobs Act was enacted in October 2004. FSP 109-2 states that an enterprise is allowed time beyond the financial reporting period of enactment to evaluate the effect of the Jobs Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS 109. We have adopted FSP 109-2 and the adoption did not have any impact on our financial position or results of operations as it did not apply.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments in determining the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We regularly evaluate our estimates, including those related to revenue recognition, customer arrangements, collectibility of accounts receivable, valuation of assets, and contingencies and litigation. When making estimates, we consider our historical experience, our knowledge of economic and market factors and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We believe that the following critical accounting policies represent areas where significant judgments and estimates have been used in the preparation of our consolidated financial statements.

Revenue Recognition

We derive our revenue from three sources: (i) product revenue, which includes license fees for products sold as software or on appliances, subscription-based license fees, and transaction-based license fees; (ii) service revenue, which includes support and maintenance fees, consulting fees, and training fees; and (iii) intellectual property and other revenue which includes patent license agreement fees and the sale of distribution rights. As described below, significant management judgments and estimates must be made and used in connection with the revenue recognized in any accounting period. Material differences may result in the amount and timing of our revenue for any period based on the judgments and estimates made by our management.

We recognize revenue in accordance with Statement of Position (“SOP”) 97-2, Software Revenue Recognition (“SOP 97-2”), as amended by SOP 98-9, Modification of SOP 97-2, “Software Revenue Recognition” With Respect to Certain Transactions (“SOP 98-9”).

We make significant judgments related to revenue recognition. Specifically, in connection with each transaction involving our products, we must evaluate whether: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) our fee is fixed or determinable, and (iv) collectibility is probable. We apply these criteria as discussed below.

 

    Persuasive evidence of an arrangement exists. We require a written contract, signed by both the customer and us, or a purchase order from those customers that have previously negotiated a standard end-user license arrangement or a volume purchase agreement with us prior to recognizing revenue on an arrangement.

 

    Delivery has occurred. We deliver software to our customers physically or electronically. For physical deliveries, our standard transfer terms are typically free on board, or FOB, shipping point. For electronic deliveries, delivery occurs when we provide the customer access codes or “keys” that allow the customer to take immediate possession of the software.

 

    The fee is fixed or determinable. Our determination that an arrangement fee is fixed or determinable depends principally on the arrangement’s payment terms. Our standard payment terms require the arrangement fee to be due within 90 days. Where these terms apply, we regard the fee as fixed or determinable, and we recognize revenue upon delivery (assuming other revenue recognition criteria are met). If payment terms do not meet this standard, which we refer to as “extended payment terms,” we do not consider the fee to be fixed or determinable and generally recognize revenue when customer installments are due and payable.

 

   

Collectibility is probable. To recognize revenue, we must judge collectibility of the arrangement fees, which we do on a customer-by-customer basis pursuant to our credit review policy. We typically sell to customers with whom we have a history of successful collection. For new customers, we evaluate the

Table of Contents
 

customer’s financial position and ability to pay. If we determine that collectibility is not probable based upon our credit review process or the customer’s payment history, we recognize revenue when payment is received.

We allocate revenue on software transactions (referred to as an “arrangement” in the accounting literature) involving multiple elements to each undelivered element based on their respective fair values. The residual is allocated to the product license. Our determination of fair value of each element in multiple element arrangements is based on vendor-specific objective evidence (“VSOE”). We limit our assessment of VSOE for each element to the price charged when the same element is sold separately.

Valuation of Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. A considerable amount of judgment is required when we assess the realization of receivables, including assessing the probability of collection and the current credit-worthiness of each customer. We must make estimates of the collectibility of our accounts receivable. We specifically analyze accounts receivable, including review of historical bad debts, customer credit-worthiness, current economic trends, aging of the balance and estimated collectibility percentages for different aging ranges, and changes in our customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of certain of our customers were to deteriorate, resulting in an impairment of their ability to make payments, we might record a specific allowance against amounts owed to us by those customers, and thereby reduce the vale of the receivable to the amount we reasonably believe will be collected. If all collection efforts have been exhausted, we would write off the receivable against the allowance.

Valuation of Long-Lived Assets and Goodwill

We assess the impairment of identifiable intangibles, long-lived assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important, which could trigger an impairment review, include the following:

 

  significant underperformance relative to historical or projected future operating results;

 

  significant changes in the manner or our use of the acquired assets or the strategy for our overall business;

 

  significant negative industry or economic trends;

 

  significant decline in our stock price for a sustained period; and

 

  our market capitalization relative to our net book value.

We evaluate goodwill at least on an annual basis for indications of impairment based on our fair value as determined by our market capitalization in accordance with SFAS 142, Goodwill and Other Intangible Assets (“SFAS 142”). If this evaluation indicates that the value of the goodwill may be impaired, we make an assessment of the impairment of the goodwill using the two-step method prescribed by SFAS 142. Any such impairment charge could be significant and have a material adverse effect on our reported financial statements. We did not record any impairment charges on our goodwill during 2005 or 2004. As of December 31, 2005, we had goodwill of $48.1 million.

Accrual for Anticipated Operating Lease Losses

We assess anticipated operating lease losses whenever we determine that our usage of our facility space will be impacted by business conditions including mergers and acquisitions activity and subsequently reevaluate those every time when sub-lease is entered into or exited. Changing market conditions make anticipated operating lease losses not easily determinable. During 2003 we recognized a charge of $996,000 related to

 

37

potential losses on an operating lease in Slough, United Kingdom that was included in our consolidated statement of operations as Merger-related and other costs. The charge was estimated to include required repairs, remaining lease liabilities, and brokerage fees, offset by estimated sublease income. During 2004 we recognized an additional charge of $168,000 on this same lease that was included in our consolidated statement of operations as Merger-related and other costs due to a revised estimate of the term of expected subleases on the building. During 2005, we recognized a $296,000 credit related to this same lease that was included in our consolidated statement of operations as Merger-related and other costs due to the combined cost of the final lease settlement payments, commissions, brokerage fees, and legal fees related to the termination of this lease being less than the existing accrual for the loss on the lease. During 2004, we recognized a charge of $183,000 related to potential losses on an operating lease in Palo Alto, California that was included in our consolidated statement of operations as Merger-related and other costs. The charge was estimated to include remaining lease liabilities and brokerage fees, offset by estimated sublease income. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than our rent payments due to a weak office rental market in and around Palo Alto. Estimates related to sublease costs and income are based on assumptions regarding the period required to locate and contract with a sublessee, sublease rates, and brokerage fees. Each reporting period we review these estimates, and to the extent that our assumptions change and/or actual charges are incurred, the ultimate charge for the loss on this operating lease could vary from our current estimates.

Item 7A—Quantitative and Qualitative Disclosures About Market Risk

We currently do not use financial instruments to hedge operating expenses in Australia, Bulgaria, Japan, New Zealand, the Netherlands, Singapore, Switzerland, or the United Kingdom denominated in the respective local currency. We assess the need to utilize financial instruments to hedge currency exposures on an ongoing basis.

We do not use derivative financial instruments for speculative trading purposes, nor do we hedge our foreign currency exposure in a manner that entirely offsets the effects of changes in foreign exchange rates. We regularly review our hedging program and may as part of this review determine at any time to change our hedging program.

Interest Rate Sensitivity

The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk. Some of the securities that we have invested in may be subject to market risk. This means that a change in prevailing interest rates may cause the fair value of the investment to fluctuate. For example, if we hold a security that was issued with a fixed rate equal to the then-prevailing interest rate and the prevailing interest rate later rises, the fair value of our investment will decline. To minimize this risk, we maintain our portfolio of cash equivalents in commercial paper and money market funds. In general, our investments are not subject to market risk because the interest paid on these funds fluctuates with the prevailing interest rate. As of December 31, 2005, none of our cash equivalents were subject to market risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Tumbleweed Communications Corp.:

We have audited the accompanying consolidated balance sheets of Tumbleweed Communications Corp. and subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of operations, stockholders’ equity and comprehensive loss, and cash flows for each of the years in the three-year period ended December 31, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of Tumbleweed Communications Corp. and subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Tumbleweed Communications Corp.’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 16, 2006, expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Tumbleweed Communications Corp.:

We have audited management’s assessment, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A, that Tumbleweed Communications Corp. maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management of Tumbleweed Communications Corp. is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting of Tumbleweed Communications Corp. 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 included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and 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 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 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, management’s assessment that Tumbleweed Communications Corp. maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by COSO. Also, in our opinion, Tumbleweed Communications Corp. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Tumbleweed Communications Corp. and subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of operations, stockholders’ equity and comprehensive loss, and cash flows for each of the years in the three-year period ended December 31, 2005, and our report dated March 16, 2006, expressed an unqualified opinion on those consolidated financial statements.

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years ended December 31, 2005, 2004, and 2003

(1)    Organization

Tumbleweed Communications Corp. (“Tumbleweed”) is a recognized leader in providing secure Internet communication solutions for enterprise and government customers of all sizes. With Tumbleweed products, organizations can block security threats, protect information, safely conduct business online, and reduce their cost of doing business.

(2)    Summary of Significant Accounting Policies

Basis of Presentation and Consolidation Policy

The accompanying consolidated financial statements include the accounts of Tumbleweed and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations of Tumbleweed’s wholly-owned subsidiaries, Valicert, Inc. (“Valicert”), Incubator, Limited (“Incubator”), and Corvigo, Inc. (“Corvigo”), have been included commencing June 23, 2003, March 15, 2004, and March 18, 2004, the effective dates of those acquisitions, respectively.

Cash and Cash Equivalents

Tumbleweed considers all highly liquid investments purchased with remaining maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

Financial instruments, which potentially subject Tumbleweed to concentrations of credit risk, consist primarily of cash equivalents and accounts receivable. Tumbleweed’s cash equivalents generally consist of money market mutual funds with qualified financial institutions. To reduce credit risk with accounts receivable, Tumbleweed performs periodic evaluations of its customers’ financial condition and, when necessary, records an allowance for credit losses. No single customer comprised 10% or more of Tumbleweed accounts receivable balance at December 31, 2005. One customer comprised 14% of Tumbleweed’s accounts receivable balance, net of allowance for doubtful accounts, at December 31, 2004. This balance was collected in full in the first quarter of 2005. For 2005, 2004, and 2003, respectively, no single customer comprised 10% or more of Tumbleweed’s revenue.

Property and Equipment

Property and equipment is stated at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful life of the asset, generally 2 to 5 years for computers, software, furniture, and equipment; and the shorter of the estimated useful life of the asset or the remaining lease term for leasehold improvements. Tumbleweed recorded depreciation expense of $1.1 million, $1.5 million, and $1.4 million, for 2005, 2004, and 2003, respectively.

Maintenance and repairs are recorded as expenses as incurred. Renewals and betterments that materially extend the lives of assets are capitalized and depreciated. Upon disposal, the assets’ cost and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is recorded in the consolidated statement of operations.

Capitalized Software

Development costs incurred in the research and development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility in the form of a working model

 

46

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

has been established. To date, capitalized costs for software development have not been material. The period between the achievement of technological feasibility and the general release of Tumbleweed’s products has typically been of short duration.

Letters of Credit

As of December 31, 2005, Tumbleweed included restricted cash in the amount of $24,000 as a part of Other current assets on its consolidated balance sheet. Tumbleweed had restricted cash in the amounts of $541,000 and $500,000 included as a part of Other assets on its consolidated balance sheets as of December 31, 2005 and 2004, respectively. The restricted cash primarily relates to letters of credit held by the lessors of Tumbleweed’s Redwood City, California, Palo Alto, California, and Sofia, Bulgaria office operating leases.

Goodwill and Intangible Assets

Tumbleweed assesses the impairment of identifiable intangibles, long-lived assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that are considered important, which could trigger an impairment review, include the following:

 

    significant underperformance relative to historical or projected future operating results;

 

    significant changes in the manner or use of the acquired assets or the strategy for the overall business;

 

    significant negative industry or economic trends;

 

    significant decline in Tumbleweed’s stock price for a sustained period; and

 

    Tumbleweed’s market capitalization relative to its net book value.

Recoverability of intangible assets held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. 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 fair value of the assets, generally using discounted net cash flows. Assets to be disposed of are reported at the lower of their carrying amount or fair value less cost to sell.

In connection with the acquisitions of Corvigo, Incubator, and Valicert on March 18, 2004, March 15, 2004, and June 23, 2003, respectively, Tumbleweed recognized $33.4 million, $1.4 million, and $13.3 million of goodwill, respectively, representing the excess of the respective purchase prices over the fair values of the acquired net tangible and identified intangible assets. In accordance with the provisions of Statement of Financial Accounting Standards (“SFAS”) 142, Goodwill and Other Intangible Assets, (“SFAS 142”), the goodwill acquired in the Corvigo, Incubator, and Valicert acquisitions will not be amortized, but instead, the goodwill balances will be tested for impairment at least annually and more frequently if certain impairment conditions exist. Any future impairment loss related to the goodwill recorded in connection with the acquisitions of Corvigo, Incubator, and Valicert will not be deductible by Tumbleweed for federal income tax purposes.

Revenue Recognition

Tumbleweed derives its revenue from three sources: (i) product revenue, which includes license fees for products sold as software or on appliances, subscription-based license fees, and transaction-based license fees; (ii) service revenue, which includes support and maintenance fees, consulting fees, and training fees; and (iii) intellectual property and other revenue which includes patent license agreement fees and the sale of distribution rights. As described below, significant management judgments and estimates must be made and used in connection with the revenue recognized in any accounting period. Material differences may result in the

 

47


Table of Contents

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

amount and timing of revenue for any period if management made different judgments or utilized different estimates.

Tumbleweed recognizes revenue in accordance with Statement of Position (“SOP”) 97-2, Software Revenue Recognition (“SOP 97-2”), as amended by SOP 98-9, Modification of SOP 97-2, “Software Revenue Recognition” With Respect to Certain Transactions (“SOP 98-9”), and generally recognizes revenue when all of the following criteria are met as set forth in paragraph 8 of SOP 97-2: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred; (3) the fee is fixed or determinable; and (4) collectibility is probable. Tumbleweed allocates revenue on software transactions (referred to as an “arrangement” in the accounting literature) involving multiple elements to each undelivered element based on their respective fair values. The residual is allocated to the product license. Tumbleweed’s determination of fair value of each element in multiple element arrangements is based on vendor-specific objective evidence (“VSOE”). Tumbleweed limits its assessment of VSOE of fair value for each element to the price charged when the same element is sold separately.

Tumbleweed’s recognition of revenue is based on its assessment of the probability of collecting the accounts receivable balance on a customer-by-customer basis. As a result, the timing or amount of revenue recognition is dependent on the assessment of collectibility made at the time of transaction. Tumbleweed assesses collectibility based on a number of factors, including transaction history and the creditworthiness of the customer. Tumbleweed does not request collateral from its customers. If Tumbleweed determined that collection of a fee is not probable, it defers the fee and recognizes revenue upon receipt of payment.

Tumbleweed considers payment terms where fees are due within ninety days to be normal. Payment terms beyond ninety days are considered extended and not fixed or determinable. For contracts with extended payment terms, revenues are recognized when fees become due and payable.

Arrangements that include consulting services are evaluated to determine whether those services are essential to the functionality of other elements of the arrangement. When services are not considered essential, the revenue allocable to the services is recognized separately from the software, provided VSOE of fair value exists. If Tumbleweed provided consulting services that are considered essential to the functionality of the software products, both the product revenue and service revenue are recognized under contract accounting in accordance with the provisions of SOP 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts. Revenue from these arrangements is recognized under the percentage of completion method based on the ratio of direct labor hours incurred to date to total projected labor costs except in limited circumstances where completion status cannot be reasonably estimated, in which case the completed contract method is used.

Tumbleweed’s software products are typically fully functional upon delivery and do not require significant modification or alteration. For arrangements where services are not essential to the functionality of the software, customers typically purchase consulting services to facilitate the adoption of Tumbleweed’s technology, but they may also decide to use their own resources or appoint other professional service organizations to perform these services. Software products are generally billed separately and independently from professional services, which are generally billed on a time-and-materials basis. For time-and-materials contracts, Tumbleweed recognizes revenue as the services are performed. Tumbleweed occasionally offers fixed fee professional services engagements. For fixed dollar consulting contracts with milestones or acceptance provisions, revenue is recognized upon completion of a milestone or acceptance, if applicable.

Tumbleweed recognizes revenue from patent license agreements and from the sale of distribution rights when (i) the patent license or distribution agreement is executed, (ii) the amounts due are fixed, determinable, and billable, and (iii) collection of the resulting receivable is probable.

Tumbleweed typically grants its customers a warranty which guarantees that its products will substantially conform to its current specifications for 60 days from the delivery date. Services to be provided under a warranty are consistent with the services performed under support and maintenance purchased by almost all of Tumbleweed’s customers. Tumbleweed provides for the estimated cost of product and service warranties based on specific warranty claims received, provided that it is probable that a liability exists, and provided the cost to repair or otherwise satisfy the claim can be reasonably estimated. The amount of the reserve recorded is equal to the costs to repair or otherwise satisfy the claim. Historically, costs related to warranty claims not covered by a support and maintenance agreement have not been significant.

Advertising

Tumbleweed expenses advertising costs as incurred. Total advertising expense was $111,000, $179,000, and $100,000 for 2005, 2004, and 2003, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recorded to reduce deferred tax assets to an amount whose realization is more likely than not. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Stock-Based Compensation

Tumbleweed’s stock-based compensation program is a broad-based, long-term retention program that is intended to attract and retain employees and align stockholder and employee interests. Tumbleweed accounts for its stock-based compensation arrangements for employees using the intrinsic-value method pursuant to Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees (“APB 25”). As such, stock-based compensation expense is recorded for fixed plan stock options on the date of grant when the fair value of the underlying common stock exceeds the exercise price for stock options or the purchase price for issuance or sales of common stock. Expense associated with stock-based compensation is amortized on an accelerated basis over the vesting period of the individual award consistent with the method described in FASB Interpretation 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans.

During 2005, Tumbleweed recorded deferred stock-based compensation of $178,000 to recognize the fair value of stock options granted to certain non-employees for professional services. The assumptions used to value the option grants were a contractual term of 10 years, volatility of 100%, risk-free interest rate of 4.15%, and dividend yield of 0%. This deferred stock-based compensation is amortized over twelve month periods, which are the expected periods over which the related services will occur. Stock-based compensation expense recognized during 2005 also included expense resulting from a separation agreement with a former employee. The separation agreement modified the former employee’s existing stock options by extending the vesting period beyond the original terms of the stock option grants.

During 2004, Tumbleweed recorded deferred stock-based compensation of $351,000 to recognize the fair value of stock options granted to certain non-employees for professional services. The assumptions used to value

 

49


Table of Contents

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

the option grants were a contractual term of 10 years, volatility of 100%, risk-free interest rates ranging from 2.58% to 3.27% depending on the date of the grant, and dividend yield of 0%. This deferred stock-based compensation was amortized over twelve month periods, which are the expected periods over which the related services were expected to occur.

During, 2004, Tumbleweed recorded deferred stock-based compensation of $1,397,000 for the difference at the effective date of the acquisition of Corvigo between the exercise price and the fair value of the common stock underlying the unvested options assumed upon the acquisition, multiplied by the ratio representing the remaining vesting period of the options assumed. During 2003, Tumbleweed recorded deferred stock compensation of $528,000 for the difference at the effective date of the acquisition of Valicert between the exercise price and the fair value of the common stock underlying the unvested options assumed upon the acquisition. Amortization of deferred stock compensation expense of approximately $510,000, $640,000, and $166,000 was recognized in 2005, 2004 and 2003, respectively.

Had stock-based compensation expense for Tumbleweed’s stock-based compensation plans been determined consistent with the fair value approach set forth in SFAS 123, Accounting for Stock-Based Compensation (“SFAS 123”), Tumbleweed’s net losses for 2005, 2004, and 2003, would have been as follows (in thousands, except per share amounts):

   $ (3,909 )   $ (7,497 )   $ (9,187 )

Basic and diluted net loss per share pro forma

   $ (0.29 )   $ (0.33 )   $ (0.40 )
                        

For purposes of computing pro forma net loss, the fair value of each option grant was estimated on the date of grant using a Black-Scholes option pricing model. The assumptions used to value the option grants are stated as follows:

 

     Years Ended December 31,  
     2005     2004     2003  

Stock options:

      

Expected life

   4.0 years     4.0 years     4.0 years  

Volatility

   89 %   123 %   136 %

Risk-free interest rate

   3.99 %   3.10 %   2.54 %

Dividend yield

   0 %   0 %   0 %

Options granted to non-employees are considered compensatory and are accounted for at fair value pursuant to SFAS 123.

In December 2004, the FASB issued SFAS 123 (revised 2004), Share-Based Payment (“SFAS 123R”), which revises SFAS 123 and supersedes APB 25. SFAS 123R requires Tumbleweed to recognize in its financial statements the fair value of all share-based payments to employees, including grants of employee stock options,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

effective at the beginning of the next fiscal year that starts after June 15, 2005. Tumbleweed will adopt SFAS 123R in the first quarter of 2006, beginning January 1, 2006. The pro forma disclosures previously permitted under SFAS 123 will no longer be an alternative to financial statement recognition. Under SFAS 123R, Tumbleweed must determine the appropriate fair value model to be used for valuing share-based payments, the amortization method for compensation cost and the transition method to be used at date of adoption. The transition methods include modified prospective and modified retroactive adoption options. Under the modified retroactive options, prior periods may be restated either as of the beginning of the year of adoption or for all periods presented. The modified prospective method requires that compensation expense be recorded for all unvested stock options and restricted stock at the beginning of the first quarter of adoption of SFAS 123R, while the retroactive methods would record compensation expense for all unvested stock options and restricted stock beginning with the first period restated. Tumbleweed is evaluating the requirements of SFAS 123R and expects that the adoption of SFAS 123R will have a material adverse impact on its consolidated results of operations and earnings per share. Tumbleweed has not yet determined the method of adoption or the effect of adopting SFAS 123R, and has not determined whether the adoption will result in amounts that are similar to the current pro forma disclosures under SFAS 123.

On July 19, 2005, Tumbleweed’s Board of Directors approved the acceleration of vesting of certain unvested stock options with exercise prices equal to or greater than $3.82 per share previously awarded to its employees (including its executive officers) and its directors under its stock option plans. The acceleration of vesting was effective for stock options outstanding as of July 19, 2005. Options to purchase approximately 1.7 million shares of common stock were accelerated. All of the options accelerated had exercise prices greater than Tumbleweed’s common stock price of $3.24 on the date of acceleration. The weighted average exercise price of the options accelerated was $5.00. Since the exercise price of all of the accelerated options exceeded Tumbleweed’s common stock price on the date of acceleration, no stock-based compensation expense was recognized as a result of the acceleration. The purpose of the acceleration was to enable Tumbleweed to avoid recognizing compensation expense associated with these options in future periods in its consolidated statement of operations upon adoption of SFAS 123R.

Net Loss Per Share

Basic net loss per common share has been computed using the weighted average number of shares of common stock outstanding during the period, less shares subject to repurchase. The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share amounts):

 

     Years Ended December 31,

Tumbleweed excludes potentially dilutive securities from its diluted net loss per share computation when their effect would be antidilutive to net loss per share amounts. The following potential common shares were excluded from the net loss per share computation (in thousands):

 

     Years Ended December 31,
     2005    2004    2003

Warrants and options excluded for which the exercise price was less than the average fair market value of Tumbleweed’s common stock during the period but were excluded as inclusion would decrease net loss per share

   2,385    4,551    3,724

Warrants and options excluded due to the exercise price exceeding the average fair market value of Tumbleweed’s common stock during the period

   7,082    3,804    2,266
              

Total potential common shares excluded from diluted net loss per share

   9,467    8,355    5,990
              

Fair Value of Financial Instruments

The fair values of Tumbleweed’s cash, cash equivalents, accounts receivable and accounts payable approximate their carrying values due to the short maturity or variable-rate structure of those instruments.

Deferred Revenue and Accounts Receivable

Tumbleweed records as deferred revenue any billed amounts due from customers in excess of revenues recognized. Advance payments are also recorded as deferred revenue until the products are shipped, services are delivered, or obligations are met. Accounts receivable includes amounts due from customers for which revenue has been recognized or amounts are legally due. Tumbleweed evaluates the collectibility of its accounts receivable based on a combination of factors. In cases where Tumbleweed is aware of circumstances that may impair a specific customer’s ability to meet its financial obligations, Tumbleweed records a specific allowance against amounts owed to it by that customer, and thereby reduces the net recognized receivable to the amount it reasonably believes will be collected. If all collection efforts have been exhausted, Tumbleweed writes off the receivable against the allowance. In addition, Tumbleweed analyzes its accounts receivable balance in total, including review of historical bad debts, current economic trends, aging of the balances and estimated collectibility percentages for different aging ranges, and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Specifically, there are significant judgments related to the allowance for doubtful accounts, the valuation of long-term assets, accrued liabilities, accrued merger-related and other costs, and revenue recognition. Actual results could differ from those estimates.

Foreign Currency

The functional currency for each foreign subsidiary is its respective local currency. Accordingly, all assets and liabilities related to these operations are translated at the current exchange rates at the end of each period. The resulting cumulative translation adjustments are recorded directly to the accumulated other comprehensive

loss account in stockholders’ equity. Revenues and expenses are translated at average exchange rates in effect during the period. Foreign currency transaction gains and losses are included in the results of operations. At December 31, 2005 and 2004, no foreign currency transactions were hedged.

Recent Accounting Pronouncements

In May 2005, the FASB issued SFAS 154, Accounting Changes and Error Corrections – a replacement of APB Opinion No. 20 and FASB Statement No. 3 (“SFAS 154”). SFAS 154 requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change in nondiscretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the accounting change. SFAS 154 also requires that a change in depreciation, amortization, or depletion method for long-lived, nonfinancial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in fiscal years beginning after the date this Statement is issued. Tumbleweed will adopt the provisions of SFAS 154 in the first quarter of 2006, beginning January 1, 2006.

In March 2005, the SEC issued Staff Accounting Bulletin 107, Share-Based Payment (“SAB 107”) regarding the SEC’s interpretation of SFAS 123R. This interpretation expresses the views of the SEC regarding the interaction between SFAS 123R and certain SEC rules and regulations and provides the SEC’s views regarding the valuation of share-based payment arrangements for public companies. In particular, SAB 107 provides guidance related to share-based payment transactions with non-employees, the transition from nonpublic to public entity status, valuation methods, the accounting for certain redeemable financial instruments issued under share-based payment arrangements, the classification of compensation expense, non generally accepted accounting principles financial measures, first-time adoption of SFAS 123R in an interim period, capitalization of compensation cost related to share-based payment arrangements, the accounting for income tax effects of share-based payment arrangements upon adoption of SFAS 123R, the modification of employee share options prior to adoption of Statement 123R and disclosures in Management’s Discussion and Analysis subsequent to adoption of SFAS 123R. Tumbleweed will adopt SAB 107 in connection with its adoption of SFAS 123R in the first quarter of 2006, beginning January 1, 2006, which is expected to have a material adverse impact on its consolidated results of operations and earnings per share.

FASB Staff Position 109-2, Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004 (“FSP 109-2”), provides guidance under SFAS 109, Accounting for Income Taxes, with respect to recording the potential impact of the repatriation provisions of the American Jobs Creation Act of 2004 (the “Jobs Act”) on enterprises’ income tax expense and deferred tax liability. The Jobs Act was enacted in October 2004. FSP 109-2 states that an enterprise is allowed time beyond the financial reporting period of enactment to evaluate the effect of the Jobs Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS 109. Tumbleweed has adopted FSP 109-2 and the adoption did not have any impact on its financial position or results of operations as it did not apply.

(3)    Business Combinations

On March 18, 2004, Tumbleweed completed the acquisition of Corvigo, an anti-spam appliance vendor. The acquisition was entered into to strengthen Tumbleweed’s position in the anti-spam and email security markets and to accelerate Tumbleweed’s distribution plans through the addition of resellers already selling the Corvigo

appliance. The purchase price of $40.9 million consisted of an exchange of 4,732,284 shares of Tumbleweed’s common stock with a fair value of $32.8 million based on the fair value of Tumbleweed’s common stock on the date of the acquisition, cash paid of $6.0 million, assumed stock options with a fair value of $1.3 million, severances for former Corvigo employees of $97,000, and other acquisition-related costs of $727,000, consisting primarily of legal fees, banking fees, and accounting fees.

On March 15, 2004, Tumbleweed completed the acquisition of Incubator, a reseller of Tumbleweed’s products. The acquisition was entered into to expand Tumbleweed’s sales in Europe. The purchase price of $1.7 million consisted of an exchange of 224,278 shares of Tumbleweed’s common stock with a fair value of $1.6 million based on the fair value of Tumbleweed’s common stock on the date of the acquisition and other acquisition-related costs of $119,000, consisting of legal and accounting fees.

As part of the acquisition of Incubator, Tumbleweed agreed that in the event that a certain sales goal was met in Tumbleweed’s European sales region in the year ending December 31, 2004, Tumbleweed’s purchase price for Incubator would increase by the exchange of additional shares of Tumbleweed’s common stock. During the three months ended September 30, 2004, the purchase agreement was amended to issue 62,509 shares to the former owners of Incubator worth $183,000 based on the fair value of Tumbleweed’s stock on the date of issuance as consideration for progress towards the European sales goal in the first six months of 2004. In addition, in the event that specified sales goals were met in Tumbleweed’s European sales region for the two-year period ending December 31, 2005, Tumbleweed’s purchase price for Incubator would increase by the exchange of additional shares of Tumbleweed’s common stock worth $1,000,000 plus 10% of the amount of Tumbleweed’s European sales in excess of the sales goal for the year ending December 31, 2005. The sales goals for the European sales region for the year ending December 31, 2004 and the two-year period ending December 31, 2005 were not met. As a result of these sales goals not being met, there is no further contingent purchase price related to the acquisition of Incubator.

On June 23, 2003, Tumbleweed acquired Valicert, which develops and licenses secure Internet communications and identity validation software for file transfer, financial messaging, and business process integration. The merger was entered into to combine the two companies into a single, more competitive industry participant. The acquisition was accounted for using the purchase method of accounting and accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the acquisition date. The purchase price of $17.0 million consisted of an exchange of 9,713,634 shares of Tumbleweed’s common stock with a fair value of $13.0 million based on the average fair value of Tumbleweed’s stock two days before and two days after the announcement date of February 18, 2003, assumed stock options with a fair value of $1.7 million, severances for former Valicert employees of $276,000, and other acquisition-related costs of $2.0 million, consisting primarily of payments for legal fees, investment banking fees, financial printing fees, accounting fees, and proxy mailing fees.

As of December 31, 2005, in connection with the acquisitions of Corvigo, Incubator, and Valicert on March 18, 2004, March 15, 2004, and June 23, 2003, respectively, Tumbleweed has $33.4 million, $1.4 million, and $13.3 million of goodwill, respectively, representing the excess of the respective purchase prices over the fair values of the acquired net tangible and identified intangible assets. During the last three quarters of 2004, Tumbleweed reduced its goodwill balance related to the Corvigo acquisition by $1.4 million to reduce to fair value unvested stock options assumed in the acquisition and increased its goodwill balance related to the Corvigo acquisition by $93,000 due to actual expenditures for accounting and legal acquisition-related costs being higher than previously estimated. During the second quarter of 2004, Tumbleweed increased its goodwill balance related to the Incubator acquisition by $15,000 due to actual expenditures for accounting and legal acquisition-related costs being higher than previously estimated. During the last two quarters of 2003, Tumbleweed reduced its goodwill balance related to the Valicert acquisition by $50,000 due to actual expenditures for severance costs for former Valicert employees and other acquisition-related costs being less than previously estimated.

Merger-related and Other Costs

Merger-related and other costs of a net credit of $96,000 for 2005 consist of a $296,000 credit related to the termination of an operating lease in Slough, United Kingdom partially offset by a $200,000 severance cost associated with the resignation of our former Chief Executive Officer. The combined cost of the final lease settlement payments, commissions, brokerage fees, and legal fees related to the termination of the Slough lease

was less than the existing accrual for the loss on the lease, resulting in the expense credit. The Slough lease was assumed during the acquisition of Interface, Inc. in 2000 and covered approximately 13,000 square feet of office space. The lease was for a term ending in 2020 with quarterly rent payments of approximately $65,000. The final lease settlement payment for the Slough lease of approximately $113,000 was made in July 2005.

Merger-related and other costs of $1.1 million for 2004 consist of $703,000 of severance costs for Tumbleweed employees terminated in connection with the Corvigo acquisition and the sale of Tumbleweed’s offshore development subsidiary in India to a third party in June of 2004, $183,000 related to anticipated losses on an operating lease in Palo Alto, California, $168,000 related to anticipated losses on an operating lease in Slough, United Kingdom, a credit of $44,000 for a gain on the sale of Tumbleweed’s offshore development center subsidiary in India, and $68,000 of other merger-related costs. The operating lease in Palo Alto was assumed during the acquisition of Corvigo and covers approximately 12,000 square feet of office space. The lease is for a term ending in 2007 with current monthly rent payments of approximately $22,000. Subsequent to the acquisition of Corvigo, Tumbleweed decided to vacate the Palo Alto facility. The $183,000 charge was recorded due to a revised estimate of the period required to locate and contract with a sublessee and sublease rates. As a result of the new estimate, the existing accrual for the loss on the lease was found to be insufficient and the remaining balance for that liability was reclassified on the consolidated balance sheet from Accrued liabilities to Accrued merger-related and other costs to be tracked along with the liability resulting from the revised estimate recorded in the three months ending September 30, 2004. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than Tumbleweed’s rent payments due to a weak office rental market in and around Palo Alto. The operating lease in Slough was assumed during the acquisition of Interface, Inc. in 2000 and covered approximately 13,000 square feet of office space. The lease was for a term ending in 2020 with quarterly rent payments of approximately $65,000. The $168,000 charge was recorded due to a revised estimate of the term of expected subleases on the building. Tumbleweed’s offshore development center subsidiary in India was acquired in the acquisition of Valicert and supported Tumbleweed’s engineering, customer support, and consulting functions. This subsidiary was sold to consolidate Tumbleweed’s offshore development in its existing Bulgaria location.

(4)    Acquired Workforce

In September 2003, Tumbleweed issued 86,538 shares of stock to a company to convert certain former contract engineers to employees in its offshore development center in Bulgaria. Since this acquisition was not considered to be an acquisition of a business, Tumbleweed recorded an acquired workforce intangible asset of $476,000 to recognize the fair value of the stock issued. Tumbleweed amortized this intangible asset over its estimated useful life of one year. During 2004 and 2003, respectively, Tumbleweed recognized amortization expense of $337,000 and $139,000, respectively relating to the acquired workforce intangible asset. This intangible asset was amortized in full as of December 31, 2004.

Goodwill represents the excess of the purchase price over the fair value of acquired net tangible and identified intangible assets. In accordance with the provisions of SFAS 142, the goodwill acquired in the Valicert, Incubator, and Corvigo acquisitions will not be amortized, but instead, the goodwill balances will be tested for impairment at least annually and more frequently if certain impairment conditions exist. Any future impairment loss related to the goodwill recorded in connection with the acquisitions of Valicert, Incubator, and Corvigo will not be deductible by Tumbleweed for federal income tax purposes.

Loan to Bernard J. Cassidy

At December 31, 2005, Tumbleweed had a loan outstanding with a combined principal and accrued interest balance of approximately $58,000 to Mr. Cassidy, Tumbleweed’s Senior Vice President, General Counsel, and Corporate Secretary. The loan was entered into on April 2, 2001, and is evidenced by a promissory note with the full principal amount and all accrued interest due in four years. The loan was made in order to help retain Mr. Cassidy, and was used for purposes other than to purchase Tumbleweed stock. Interest on the loan is at a rate of 7% per annum which Tumbleweed believes to be the market rate at the time of the loan. In March 2006, Mr. Cassidy made a payment to Tumbleweed of approximately $45,000 which was applied against the combined principal and accrued interest balance. Tumbleweed expects the residual combined principal and accrued interest balance to be paid in full during 2006.

Loan to Jeffrey C. Smith

At December 31, 2005, Tumbleweed had a loan outstanding with a combined principal and accrued interest balance of approximately $7,000 to Mr. Smith, Tumbleweed’s former Chairman and Chief Executive Officer. The loan was entered into on June 7, 2001, and is evidenced by a full recourse promissory note with the full principal amount and all accrued interest due in five years. The loan was made in order to help retain Mr. Smith, and was used for purposes other than to purchase Tumbleweed stock. The promissory note is secured by shares of Tumbleweed’s common stock and stock options to purchase shares of Tumbleweed’s common stock that Tumbleweed issues to Mr. Smith, as well as the proceeds associated with such securities. Interest on the loan is at

 

59


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

a rate of 7% per annum which Tumbleweed believes to be the market rate at the time of the loan. Principal and interest obligations under this loan will be forgiven ratably over a period of five years beginning on the effective date of the loan. Mr. Smith resigned as a Chief Executive Officer on June 30, 2005 and entered into a transition agreement with Tumbleweed. During the transition term that is equal to two years from the Mr. Smith’s resignation date, Mr. Smith continues to participate in the outstanding loan forgiveness program that will terminate with complete forgiveness of the loan during 2006.

Legal Counsel

Gregory C. Smith, a brother of Jeffrey C. Smith, Tumbleweed’s former Chairman and Chief Executive Officer, is a partner of the law firm of Skadden, Arps, Slate, Meagher & Flom LLP (“Skadden Arps”), which began providing legal services to Tumbleweed in July 1998. Total fees paid to Skadden Arps were approximately $315,000, $802,000, and $979,000 in 2005, 2004, and 2003, respectively, for matters relating to Tumbleweed’s intellectual property, Tumbleweed’s acquisitions of Corvigo, Incubator, and Valicert, and ongoing general and other litigation matters.

Financial Advisement

Curtis H. Smith, a brother of Jeffrey C. Smith, is a principal at First Albany Capital (“First Albany”), which provided financial advisement services to Tumbleweed in 2004 related to the acquisition of Corvigo. Total fees paid to First Albany were approximately $185,000 in 2004. No fees were paid to First Albany during 2005 or 2003.

A valuation allowance against Tumbleweed’s net deferred tax assets has been established since it cannot be concluded that it is more likely than not that deferred tax assets in excess of deferred tax liabilities will be realized. The valuation allowance of $117.8 million at December 31, 2004, increased by $2.7 million to $120.5 million at December 31, 2005. Included in the December 31, 2005 valuation allowance is approximately $20.5 million related to the exercise of stock options, which will be credited to stockholders’ equity when realized for tax purposes.

In connection with the acquisitions of Corvigo in 2004 and Valicert in 2003, deferred tax assets of approximately $1.6 million and $33.5 million, respectively, were recorded. When recognized, the tax benefits of such deferred tax assets will be applied, first, to reduce to zero any goodwill related to this acquisition; second, to reduce to zero other non-current intangible assets related to this acquisition; and third, to reduce income tax expense.

As of December 31, 2005, Tumbleweed had net operating loss carryforwards for Federal and California income tax purposes of approximately $299.1 million and $89.7 million, respectively, available to reduce future income subject to income taxes. The federal net operating loss carryforwards will expire in the years 2007 through 2025 and the California net operating loss carryforwards expire in the years 2006 through 2015.

As of December 31, 2005, Tumbleweed also had research and development tax credit carryforwards for Federal and California income tax return purposes of approximately $4.9 million and $4.6 million, respectively, available to reduce future income taxes. Tumbleweed also has California Manufacturing Credit carryforwards of $262,000. The Federal research and development tax credit will expire in years 2007 through 2025. The California research and development tax credit carries forward indefinitely.

Tumbleweed’s ability to utilize the net operating losses and tax credit carryforwards in the future may be subject to substantial restriction in the event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code and similar state tax law.

(9)    Stockholders’ Equity

Under Tumbleweed’s certificate of incorporation, Tumbleweed is authorized to issue 100,000,000 shares of common stock, each with a par value of $0.001. As of December 31, 2005 and 2004, respectively, Tumbleweed has 49,492,960 and 48,154,581 shares outstanding. Tumbleweed is also authorized to issue 10,000,000 shares of preferred stock, each with a par value of $0.001. Tumbleweed has zero preferred shares outstanding as of December 31, 2005 and 2004, respectively.

1993 Stock Option Plan

On September 30, 1993, Tumbleweed adopted the 1993 Stock Option Plan (“the Plan”). In 1999, Tumbleweed’s Board of Directors approved an amendment to the plan to increase the number of shares authorized for issuance by 650,000 shares to a total of 3,768,500 authorized shares. In August 1999, Tumbleweed ceased granting further options under the Plan. Under the Plan, the exercise price for incentive options is at least 100% of the fair market value on the date of grant. The exercise price for nonqualified stock options is at least 85% of the fair market value on the date of grant. Options generally expire in 10 years. Vesting periods are determined by the Board of Directors and generally provide for 25% of the options to vest on the first anniversary date of the grant with the remaining options vesting monthly over the following 36 months.

1999 Omnibus Stock Incentive Plan

The 1999 Omnibus Stock Incentive Plan (“the Incentive Plan”) was approved by stockholders on August 3, 1999, for the benefit of Tumbleweed’s officers, directors, key employees, advisors and consultants. An aggregate of 10,882,858 shares of common stock is reserved for issuance under the Incentive Plan, which provides for the issuance of stock-based incentive awards, including stock options, stock appreciation rights, limited stock appreciation rights, restricted stock, deferred stock, and performance shares. The Incentive Plan provides for an automatic annual increase in the number of stock options available for grant of the lesser of 2,000,000 shares or 5% of the number of Tumbleweed’s outstanding shares on the last day of the immediately preceding fiscal year.

1999 Employee Stock Purchase Plan

The 1999 Employee Stock Purchase Plan (“the Purchase Plan”) was approved by stockholders on August 3, 1999, which allows eligible employees to purchase common stock at a discount from fair market value. A total of 500,000 shares of common stock has been reserved for issuance under the Purchase Plan for each fiscal year occurring during the term of the Purchase Plan, which will terminate in 2009. Tumbleweed suspended the Purchase Plan in 2002.

2000 NSO Incentive Stock Plan

The 2000 NSO Incentive Stock Plan (“the NSO Incentive Plan”) was adopted by Tumbleweed’s Board of Directors on July 10, 2000. The NSO Incentive Plan qualifies as a “broadly based” plan and is for the benefit of Tumbleweed’s officers, directors, employees, advisors, and consultants. It provides for the issuance of stock-based incentive awards, including stock options, stock appreciation rights, restricted stock, deferred stock, and performance shares or any combination of such. The options granted under the NSO Incentive Plan are not intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986. An aggregate of 4,181,500 shares of common stock are reserved for issuance under the NSO Incentive Plan, which will terminate on July 10, 2010.

Under the terms of the NSO Incentive Plan, the exercise price for stock options is determined by the Board of Directors, Compensation Committee, or Administrator, generally 100% of the fair market value on the date of grant. The option term is determined by the Administrator, generally no longer than 10 years. Vesting periods are determined by the Administrator and generally provide for 25% of the options to vest on the first anniversary date of the grant with the remaining options vesting monthly over the following 36 months.

Interface Stock Option Plans

On September 1, 2000, Tumbleweed assumed the Interface 1992 Stock Option Plan (“1992 Plan”) and 1993 Stock Option Plan for Non-Employee Directors (“Directors Plan”) in connection with the Interface acquisition. The 1992 Plan provided for the grant of both incentive stock options and non-qualified options to officers and key employees at not less than market price on the date of grant as determined by the Board of Directors. Under the 1992 Plan, options generally vest at the rate of 33% per year after one year from the date of grant and have a term of ten years. The Directors Plan provided for the grant to non-employee directors of non-qualified options at market price on the date of grant. The Directors Plan provides for discretionary grants with vesting determined at the time of grant with a term of ten years. A total of 236,000 shares of Tumbleweed’s common stock were reserved for issuance upon the exercise of stock options assumed in connection with the acquisition of Interface. Tumbleweed registered an additional 304,023 shares for issuance from the 1992 Plan, that was used to grant options to Interface employees at the time of the merger and who remain employed by Tumbleweed. The Directors Plan was terminated upon its assumption by Tumbleweed, and no further options will be granted under it.

Valicert Stock Option Plans

On June 23, 2003, Tumbleweed assumed the Valicert 1998 Stock Option Plan, the 2001 Non-Statutory Stock Plan, the 1996 Equity Incentive Plan, and the Receipt.com Plan. These stock plans provide for the grant of options and restricted stock to employees, consultants and directors. Incentive stock options are granted at fair market value on the date of grant. Non-statutory options may be offered at not less than 85% of the fair market value on the date of the grant. Options generally vest over three to four years, are immediately exercisable and have a maximum term of 10 years. The number of stock options available for grant will automatically increase on the first day of each fiscal year by an amount equal to 5% of the common stock outstanding on the last day of the preceding year, or a lesser number of shares determined by the Board of Directors through 2008. An aggregate of 4,909,487 shares of common stock is reserved for issuance under the Valicert stock option plans.

Valicert stock option plans assumed by Tumbleweed were amended to conform with Tumbleweed stock option plans. This provides Tumbleweed with the flexibility to issue additional options as needed and promotes uniformity in new options issued to ex-Valicert and Tumbleweed employees. Specifically, the 2001 Non-Statutory Stock Plan, the 1998 Stock Option Plan and the 1996 Equity Incentive Plan, were amended, including the forms of option agreements under each such plan, to conform the terms and conditions applicable to options granted under such plans to the terms and conditions applicable to options granted under Tumbleweed’s 1999 Omnibus Incentive Plan, including the form of option agreement under such plan.

In addition to conforming the terms of the Valicert stock option plans assumed by Tumbleweed to Tumbleweed’s stock option plan, the 1998 Stock Option Plan was further amended prior to the closing of the merger to provide the following:

 

    the number of shares of Valicert common stock available for grant under the 1998 Stock Option Plan immediately following the close of the merger was no less than 1.5 million shares of Valicert common stock; and

 

    the provision of the 1998 Stock Option Plan that provides for a 5% annual increase in the number of stock options available for grant under such plan shall be calculated as a percentage of the number of Tumbleweed shares issued and outstanding rather than the number of Valicert shares issued and outstanding.

Corvigo Stock Option Plan

On March 18, 2004, Tumbleweed assumed the Corvigo 2002 Stock Option Plan. This plan provides for the grant of options to employees, consultants and directors. Incentive stock options are granted at fair market value on the date of grant. Non-statutory options may be offered at not less than 85% of the fair market value on the date of the grant. Generally, 25% of the options vest on the first anniversary date of the grant with the remaining options vesting monthly over the following 36 months. Options have a maximum term of 10 years. An aggregate of 884,678 shares of common stock is reserved for issuance under the Corvigo 2002 Stock Option Plan, which will not grant new options after November 15, 2012.

Warrants

In conjunction with various financing arrangements and employment recruitment services provided to Tumbleweed in 1998, 1999, and 2001, Tumbleweed issued warrants to purchase an aggregate of approximately 583,113 shares of common stock. Additional warrants to purchase an aggregate of 289,789 shares of common stock were assumed in 2003 as a result of the merger with Valicert. As of December 31, 2005 and 2004, 645,264 and 646,119 warrants to purchase common stock remain outstanding, respectively. Of the warrants that remain outstanding at December 31, 2005, 433,330 expire in July 2006 with an exercise price of $26.93; 139,089 expire in November 2006 with an exercise price of $9.08; 3,830 expire in January 2007 with an exercise price of $15.66; 21,129 expire in April 2008 with an exercise price of $4.91; 10,266 expire in April 2008 with an exercise price of $5.84; 2,566 expire in February 2010 with an exercise price of $49.09; 1,283 expire in April 2010 with an exercise price of $49.09; and the remaining 33,771 expire in June 2011 with an exercise price of $6.66.

During 2005, no warrants were exercised. During 2004, 5,615 warrants were exercised at an exercise price of $4.07.

Stock Repurchase Program

In August 2002, Tumbleweed’s Board of Directors approved a program to repurchase up to $10.0 million of its common stock. During the year ended December 31, 2002, Tumbleweed repurchased 717,500 shares of its common stock for $796,000. Tumbleweed did not repurchase any shares of its common stock during 2003. The repurchase program was terminated in August 2003.

(10)    Employee Benefit Plan

Tumbleweed has a 401(k) plan that allows eligible employees to contribute a percentage of their compensation, limited to $14,000 ($18,000 for employees over age 50), $13,000 ($16,000 for employees over age 50), and $12,000 in 2005, 2004, and 2003, respectively. Tumbleweed did not match contributions to employees’ 401(k) plans in 2005, 2004, or 2003.

(11)    Commitments and Contingencies

Lease Commitments

Tumbleweed leases its facilities and certain equipment under operating lease agreements. The facilities leases expire at various dates through 2008. In June 1999, Tumbleweed entered into an operating lease covering approximately 40,000 square feet of office space in Redwood City, California and renewed that lease in 2003. The renewed lease expires in July 2008 with current monthly rent payments of approximately $73,000.

As a result of the Corvigo acquisition, Tumbleweed assumed an operating lease in Palo Alto, California. Subsequent to the acquisition of Corvigo, Tumbleweed decided to vacate the Palo Alto facility. The lease is for a term ending in 2007 with current monthly rent payments of approximately $22,000. Anticipated future sublease rental income is expected to be less than the rent expense due to a weak office rental market in and around Palo Alto. In 2004 Tumbleweed recognized a charge of $183,000 related to anticipated losses on this lease that was included in the consolidated statement of operations as Merger-related and other costs. The $183,000 charge was recorded due to a revised estimate of the period required to locate and contract with a sublessee and sublease rates. As a result of the new estimate, the existing accrual for the loss on the lease was found to be insufficient and the remaining balance for that liability was reclassified on the consolidated balance sheet from Accrued liabilities to Accrued merger-related and other costs to be tracked along with the liability resulting from the

 

66


Table of Contents

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

revised estimate recorded in the three months ending September 30, 2004. This office space was subleased in December 2004 for the remainder of the lease term with sublease rental income less than Tumbleweed’s rent payments due to a weak office rental market in and around Palo Alto.

Future minimum lease payments for operating leases as of December 31, 2005, are as follows (in thousands):

 

Year Ending December 31,

   Operating
Leases

2006

   $ 1,715

2007

     1,258

2008

     523
      

Future minimum lease payments

   $ 3,496
      

The amounts above will be offset by sublease receipts of $244,000 in 2006 and $20,000 in 2007.

Total rent expense under operating leases for 2005, 2004, and 2003, was $1.5 million, $1.4 million, and $1.8 million, respectively.

Contingencies

In December 2001, certain plaintiffs filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of Valicert, alleging violations of federal securities laws. In re Valicert, Inc. Initial Public Offering Securities Litigation, No. 01-CV-10889 (SAS) (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). The operative amended complaint is brought on purported behalf of all persons who purchased Valicert common stock from the date of its July 27, 2000 initial public offering (“IPO”) through December 6, 2000. It names as defendants Valicert, its former Chief Executive Officer, its Chief Financial Officer (the “Valicert Defendants”), as well as an investment banking firm that served as an underwriter for the IPO. The complaint alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriter agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to be paid to the underwriter; and (2) the underwriter arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of damages. Similar allegations have been made in lawsuits relating to more than 300 other initial public offerings conducted in 1999 and 2000, all of which have been consolidated for pretrial purposes. In February 2003, the Court issued a ruling on all defendants’ motions to dismiss, denying Valicert’s motion to dismiss the claims under the Securities Act of 1933, but granting Valicert’s motion to dismiss the claims under the Securities Exchange Act of 1934.

In June 2003, Valicert accepted a settlement proposal presented to all issuer defendants in this case. Under the proposed settlement, the plaintiffs will dismiss and release all claims against the Valicert Defendants in exchange for a contingent payment guaranty by the insurance companies collectively responsible for insuring the issuers in all the consolidated cases, and the assignment or surrender of control to the plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the guaranty, the insurers will be required to pay the amount, if any, by which $1 billion exceeds the aggregate amount ultimately collected by the plaintiffs from the underwriter defendants in all of the cases. If the plaintiffs fail to recover $1 billion and payment is required under the guaranty, Valicert would be responsible to pay its pro rata portion of the shortfall, up to the amount of the deductible retention under its insurance policy, which is $500,000. The timing and amount of payments that Valicert could be required to make under the proposed settlement will depend on several factors, principally the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

timing and amount of any payment required by the insurers pursuant to the $1 billion guaranty. The proposed settlement is subject to approval of the Court, which cannot be assured. The accompanying consolidated financial statements do not include a reserve for any potential loss, as Tumbleweed does not consider a loss to be probable at this time.

In June 2003, Tumbleweed was served with a summons and first amended complaint, captioned Liu v. Credit Suisse First Boston, et alia, alleging the violation of federal and state securities laws, purportedly on behalf of persons who acquired the common stock of Tumbleweed (other than purchasers of Tumbleweed’s IPO) from August 6, 1999 to October 18, 2000. The case was transferred to the United States District Court for the Southern District of New York, where in March 2005, the Court dismissed the case with prejudice. In June 2005 plaintiffs filed an appeal of the dismissal with the United States Court of Appeals for the Second Circuit, which remains pending. An adverse outcome in this case could harm Tumbleweed’s business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as Tumbleweed does not consider a loss to be probable at this time.

All costs incurred as a result of these legal proceedings and claims are charged to expense as incurred. Tumbleweed indemnifies its customers from third party claims of intellectual property infringement relating to the use of its products. Historically, costs related to these guarantees have not been significant. Tumbleweed is unable to estimate the potential impact of these guarantees on its future results of operations.

Item 9—Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

Item 9A—Controls and Procedures

 

(a) Evaluation of disclosure controls and procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act and are effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

 

(b) Changes in internal controls over financial reporting.

During 2005, we transitioned to a new financial system to be used for our general ledger accounting. This system is designed to enhance our financial reporting by providing more timely and accurate financial and accounting information, and by eliminating the need to transfer financial data from one financial system to another.

Other than the change mentioned above, no other changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during 2005 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Tumbleweed have been detected. Our controls and procedures are designed to provide reasonable assurance of achieving their objectives and our Chief Executive Officer and Chief Financial Officer have concluded that our controls and procedures are effective at that reasonable assurance level.

 

(c) Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended). Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2005. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control-Integrated Framework. Our management has concluded that, as of December 31, 2005, our internal control over financial reporting is effective based on these criteria. Our independent registered public accounting firm, KPMG LLP, have issued an audit report on our assessment of our internal control over financial reporting, which is included herein.
