•Cybersecurity: DDoS Protection and Cyber Threat Analytics - Computer networks continue to be targeted for cyberattacks, even more aggressively during the COVID-19 pandemic, that are aimed at disrupting, damaging, or otherwise destroying an enterprise’s ability to conduct its business or gaining unauthorized access to corporate applications and stealing valuable information. We provide a range of network security solutions under the NetScout Arbor brand that enable enterprises to protect their networks from high-volume and application-specific DDoS attacks, which are aimed at either overwhelming the network with traffic or over-exercising specific functions or features of a website with the intention to disable those functions or features. We have also developed new cybersecurity solutions for enterprises that provide greater deep-dive forensic capabilities as well as analytics that can provide visibility into anomalous behavior on the network that may be indicative of an advanced threat. These security analytics enable existing enterprise customers to leverage their historical investments in NetScout’s service assurance solutions by using the Adaptive Service Intelligence (ASI) data already being generated to support service assurance as well as cybersecurity use cases.
Government Markets
Considered as part of our enterprise vertical, we have built a strong position with federal, state and local government agencies, both in the United States and abroad. Similar to our enterprise customers, government agencies are focused on streamlining and transforming IT into more efficient and more easily managed environments. To accomplish this, agencies are turning to IT solutions that will help simplify managing and assuring their IT environments as well as reduce costs. However, governmental markets differ from enterprise markets primarily due to their purchasing cycles being influenced by potential changes in government administrators, budgetary priorities and allocated funding for key projects.
Telecommunication Service Provider Markets
Today’s service providers are focused on delivering a compelling set of services and ensuring a high-quality user experience, while also striving to minimize operational complexity, control costs and improve automation. This, coupled with the challenge of internet protocol (IP) transformation activities and complex technologies such as 5G, Long-Term Evolution (LTE), Network Functions Virtualization (NFV), Internet Protocol Television (IP-TV), wireless network (WiFi) and cloud services drives the need for a more automated and unified approach to managing service delivery and the subscriber experience. Our service provider solutions support an expanding range of use cases including:
•Service Assurance for Mobile, Fixed Line and Cable Operators - The fundamental transformation of the mobile network to all-IP enables mobile operators to build highly-scalable service delivery environments to offer new services to meet the growing subscriber demand for data, voice and video-centric services and to consolidate and simplify network operations. Mobile operators use our offerings to gain real-time, detailed IP packet-level insight and core-to-access visibility, which enables them to ensure services offered over the network and meet certain pre-defined quality levels for an optimal subscriber experience. NetScout’s service assurance solutions help service providers effectively manage capacity, assess overall network quality, take proactive steps to modify the network before issues impact subscribers, and quickly identify and troubleshoot network problems. In addition to improving the overall return on their network infrastructure investments, mobile operators using our solutions also benefit from improved network quality and unique customer insights - both of which contribute to subscriber acquisition, retention, and monetization. The growing demand for high-bandwidth triple-play services, broadband connectivity, content anywhere, IP-TV, on-demand video traffic, new extended WiFi initiatives and carrier Ethernet services presents fixed line and cable multi-system operators with significant revenue opportunities. IP has become the de facto convergence mechanism for access, distribution and core networks, enabling new service offerings and simplifying network operations while reducing total cost of operations. For example, cable operators use our solutions to monitor and manage their local area WiFi connectivity services, ensure the high-quality delivery of video to consumers outside of their homes as well as provide broadband and telephony services targeting small- and medium-sized businesses.
•Business Intelligence for Service Providers - Service providers strive to understand how the performance of their networks impact customer experience, subscriber behavior and related usage trends. By combining network traffic data with other information, including support requests, subscriber calling plans, demographic data and other details, service providers can make more timely decisions about their offerings and sales and marketing initiatives to acquire, retain and further monetize their subscribers. NetScout’s analytics deliver timely insights into a service provider’s subscribers, services, networks, and applications, as well as easy export capabilities so that this information can be integrated into their data lakes and third-party analytic platforms.
•DDoS Protection - Over the past decade, Internet Service Providers (ISPs), including leading telecommunications providers, cable multi-service operators and cloud providers, have seen significant increases in the sophistication, scale and frequency of high-volume and application-specific DDoS attacks on their networks. DDoS attacks are aimed at disrupting the online services of an ISP’s business customer by overwhelming the network with traffic or by over-exercising specific functions or features of a website with the intention to disable those functions or features. NetScout Arbor smart DDoS solutions are used by a wide range of ISPs around the world to help protect their networks against DDoS attacks, and to resell certain DDoS offerings to their enterprise customers.
Products Overview
Since our founding in 1984, we have been an industry innovator in using IP-based network traffic to help organizations manage and optimize the delivery of services and applications over their networks, improve the end-user experience and protect networks from unwanted cybersecurity threats. Using our patented ASI technology, our solutions instantaneously convert network traffic data, often referred to as wire data, into high-value metadata, or "smart data". Our offerings can help customers quickly identify and troubleshoot network and application performance issues, defend their networks from DDoS and other cybersecurity attacks, and rapidly find and isolate advanced network threats. Our solutions are typically deployed by customers as integrated hardware and software, as software only that is then integrated into commercial off-the-shelf hardware, in a virtualized environment as software only, or as a Software as a Service (SaaS) form factor. Our solutions help our customers meet the increasing demands and ever-changing technology landscape of IP networks, service, applications, and cybersecurity. In recent years, to further elevate our value proposition and address the near- and long-term needs of customers and prospects, we have delivered major product upgrades across our product lines by integrating key functionality from acquired product lines, increasing the deployment flexibility of our solutions, and adding new features and capabilities that enable us to address a broader range of use cases.

•Improve Cost Structure and Drive Efficiencies - We plan to balance our investments in key technology, product development, sales and marketing, and other initiatives that will enable us to drive long-term profitable growth with an ongoing focus on managing costs and driving efficiencies.
Support Services
Customer satisfaction is a key driver of our success. Our support programs offer customers various levels of high-quality support services to assist in the deployment and use of our solutions. We have support personnel strategically deployed across the globe to deliver 24/7 support to our premium customers. Certain support services, such as on-site support activities, are provided by qualified third-party support partners. In addition, many of our certified resellers provide Partner Enabled Support to our end users. This is especially prevalent in international locations where time zones and language, among other factors, make it more efficient for end users to have the reseller provide initial support functions. Our support also includes updates to
our software and firmware at no additional charge, if and when such updates are developed and made generally available to our commercial customer base. If ordered, support commences upon shipment or expiration of the standard warranty for software. For software, which also includes firmware, the standard warranty commences upon shipment and expires 60 to 90 days thereafter. With regard to hardware, the standard warranty commences upon shipment and expires 60 days to 12 months thereafter. We believe our warranties are consistent with commonly accepted industry standards. We expect to continue to provide support services for the acquired platforms under existing agreements and plan to explore opportunities to further simplify and standardize our support obligations over the coming years.
Manufacturing
Our manufacturing operations consist primarily of final product assembly, configuration, and testing. We purchase components and subassemblies from suppliers and construct our hardware products in accordance with NetScout standard specifications. We inspect, test and use process controls to ensure the quality and reliability of our products. We maintain an ISO 9001 quality systems registration, a certification showing that our corporate procedures and manufacturing facilities comply with standards for quality assurance and process control. We also maintain an ISO 9001:2000 quality systems registration, a certification showing that our corporate procedures comply with standards for continuous improvement and customer satisfaction.
We generally use standard parts and components for our products, which can be sourced from various suppliers. We have generally been able to obtain adequate supplies of components in a timely manner from current suppliers. While certain components, such as computer network interface cards, are currently purchased from a single supplier, we have identified alternate suppliers that we believe can be qualified relatively quickly to fulfill our needs should an issue arise with the existing supplier. Our reliance on single source suppliers is further described in Item 1A "Risk Factors."
We manufacture our products based upon near-term demand estimates resulting from sales forecasts and historical fulfillment information. However, since these forecasts have a high degree of variability because of factors that include time of year, overall economic conditions and sales employee incentives, we believe it is prudent to maintain inventory levels in advance of receipt of firm orders to ensure that we have sufficient stock to satisfy incoming orders. Our inventory management system has thus far enabled us to minimize the effects of the disruption caused by the global COVID-19 pandemic from a supply chain perspective. The potential impact of the COVID-19 pandemic on our business is further described in Item 1A "Risk Factors."
Sales and Marketing
Sales
We sell our products, support and services through a direct sales force and an indirect reseller and distribution channel.
Our direct sales force generally uses a "high-touch" sales model that consists of face-to-face meetings with customers to understand and identify their unique business challenges and requirements. In the current global pandemic environment, our sales teams have been successful in engaging customers virtually to understand their requirements and effectively design solutions. Our sales teams translate our customers' requirements into tailored business solutions that allow the customer to maximize the performance of its infrastructure and service delivery environment. Due to the complexity of the systems and the capital expenditures involved, our sales cycles typically take between three and twelve months. We build strategic relationships with our customers by continually enhancing our solution to help them address their evolving service delivery management challenges. In addition to providing a comprehensive solution to meet these needs, we continually provide software enhancements to our customers as part of their maintenance contracts with us. These enhancements are designed to provide additional and ongoing value to our existing customers to promote loyalty and the expansion of their deployment of our products. Existing customer growth is also driven by the expansion and changes in their networks as they add new infrastructure elements, new users, new locations, new applications, experience increasing service traffic volumes or encounter incremental cyber threats.
We also maintain an indirect reseller and distribution channel. Sales to customers outside the United States are primarily export sales through channel partners. Our channel partners assist us by improving our reach to customers, extending our presence in new markets, and marketing and selling our products to a broad array of organizations globally. We sell through a range of channel partners including value-added resellers, value-added distributors, resellers, and system integrators, to our enterprise, service provider and government customers. Historically and currently, we have used indirect distribution channels principally as intermediaries on contractual terms for customers with whom we do not have a contract. Our sales force meets with end user customers to present our products and solutions, conduct demonstrations, provide evaluation equipment, recommend detailed product solutions, develop product deployment designs and timelines, and assist in establishing financial and other justifications for the proposed solution. During this selling process, a channel partner, who has contracts with both the end customer and us, may be brought in to facilitate the transaction and to provide fulfillment services. In the case of
international channel partners, those services usually also include currency translation and support. In the U.S., fulfillment services are usually limited to invoicing and cash collection. Under this approach, we have limited dependence upon channel partners for the major elements of the selling process. In many cases, there are multiple channel partners with the required contractual relationships, so dependence on any single channel partner is not significant.
During the fiscal years ended March 31, 2021, 2020 and 2019, no direct customers or indirect channel partners accounted for more than 10% of our total revenue.
Marketing
Our marketing organization drives our market research, strategy, product positioning and messaging, and produces and manages a variety of programs such as customer forums, trade shows, industry events, advertising, public and analyst relations, social media, direct mail, seminars and webinars, sales promotions and other online marketing programs. These programs are focused on promoting the sale and acceptance of our solutions to further build the NetScout brand as well as the ASI, nGenius, Arbor and other applicable product brand names in the marketplace.
Key elements of our marketing strategy focus on thought leadership, market positioning, market education, go to market strategies, reputation management, demand generation, and the acceleration of our strategic selling relationships with local and global resellers, systems integrators, and our technology alliance partners. During fiscal year 2021, we continued to invest in the promotion of the NetScout brand as well as the nGenius and Arbor brands as core solution-level brands in their respective markets. We expect to continue these initiatives during fiscal year 2022.
Research and Development
Our continued success depends significantly on our ability to anticipate and create solutions that will meet emerging customer requirements. We work closely with our largest enterprise and service provider customers to better understand and address their near-term and longer-term requirements. By better understanding the key, time-sensitive needs of our global customer base, we believe our development programs will continue to result in enhanced products that are able to meet the increasing challenges of an increasingly complex and dynamic global network environment.
We have invested significant financial resources and personnel into the development of our products and technology. Our continued investment in research and development is crucial to our business and our continued success in the market. We have assembled a team of highly skilled engineers with expertise in various technologies associated with our business and the technologies being deployed by our customers. We plan to continue to enhance and expand our product offerings and capabilities in the near future while integrating key capabilities from acquired product lines as appropriate. As a result, we plan to continue to invest and dedicate significant resources to our research and development activities for both our enterprise and service provider customers.
We predominantly develop our products internally, with some limited third-party contracting. We have also acquired developed technology through business acquisitions. To promote industry standards and manifest technology leadership, we participate in and support the activities and recommendations of industry standards bodies, and we also engage in close and regular dialogue with our key customers and alliance partners. These activities provide early insight into the direction of network and application performance requirements and the changing cybersecurity landscape that impacts current and emerging technologies.
Seasonality
We have experienced, and expect to continue to experience, quarterly variations in our order bookings as a result of a number of factors, including the length of the sales cycle, complexity of customer environments, new product introductions and their market acceptance and seasonal factors affected by customer projects and typical IT buying cycles. Due to these factors, we historically have experienced stronger bookings during our fiscal third and fourth quarters than in our fiscal first and second quarters.
Customers
We sell our products to enterprises, service providers and local, state, and federal governmental agencies with large-and medium-sized high-speed IP computer networks. Our enterprise customers cover a wide variety of industries, such as financial services, technology, manufacturing, healthcare, utilities, education, transportation and retail as well as government and associated agencies. Our telecommunications service provider customer group includes mobile operators, wireline operators, cable operators, internet service providers, and cloud providers.
Backlog
We produce our products on the basis of our forecast of near-term demand and maintain inventory in advance of receipt of firm orders from customers. We configure our products to customer specifications and generally deliver products shortly after receipt of the purchase order. Service engagements are also included in certain orders. Customers generally may reschedule or cancel orders with little or no penalty. We believe that our backlog at any particular time is not meaningful because it is not necessarily indicative of future sales levels. Our combined product backlog at March 31, 2021 was $27.9 million compared to $29.4 million at March 31, 2020. A majority of the backlog relates to customization and integration projects and radio frequency propagation modeling. In some cases, we have begun these projects but have not yet hit billable milestones. A majority of revenue for these projects is expected to be recognized into revenue throughout fiscal year 2022.
Competition
We compete with many companies in the markets we serve. The service assurance market, including the infrastructure, network, and application performance management markets, is highly competitive, rapidly evolving, and fragmented with overlapping technologies and a wide range of competitors, both large and small, who may deliver certain elements of our solution. Consequently, there are a number of companies who have greater name recognition and substantially greater financial, management, marketing, service, support, technical, distribution and other resources than we do. Additionally, certain competitors, either due to their size and resources or due to their technological strengths, may be able to respond more effectively than we can to new or changing opportunities, technologies, standards and customer requirements.
Principal competitive factors in our service assurance market include scalability; ability to address a large number of applications, locations and users; product performance; the ability to easily deploy into existing network environments; the ability to offer virtualized solutions; and the ability to administer and manage the solution.
While we face multiple competitors within the service assurance industry, we believe that we compete favorably on the basis of the following factors:

•our solutions look at both data and control plane traffic across an entire network; and
•our ASI technology is optimized to provide real-time information about service performance and real-time alerts to emerging service problems whereas traditional solutions are inherently latent, supporting only forensic-trouble shooting after an issue has occurred.
In the enterprise market, our competitors include companies who provide network performance management, application performance management, infrastructure performance management and other related solutions such as CA Technologies (a Broadcom Inc. business), Cisco Systems, Dynatrace, Datadog, ExtraHop, IBM, Infovista, Keysight, Viavi, Gigamon, New Relic, Riverbed Technology, Splunk and SolarWinds. In addition, we both compete with and partner with large enterprise management vendors, such as HP and IBM, who offer performance management solutions. We also compete with smaller, privately held competitors who often focus on specific vertical markets.
In the service provider market, we compete with traditional probe vendors, network equipment manufacturers, big data and analytics vendors, and virtualization vendors. These vendors include Anritsu, Cisco, Ericsson, Dell Technologies, EXFO, Huawei, IBM, Infovista, Niksun, Polystar (an Elisa Oyj business), Radcom, Splunk, Nokia and Viavi. We face additional competitive threats from startups and new entrants that seek to offer innovative solutions in an industry characterized by rapid technological change.
In the cybersecurity market, we face a range of competitors, including those that may have greater name recognition and substantially greater financial, management, marketing, service, support, technical, distribution and other resources than we do. We believe that the scalability of our solutions, flexible deployment, and price-performance of our cybersecurity solutions positions us well to compete against both larger network equipment and security companies and smaller niche security solutions vendors.
In the DDoS solutions market, we compete under the NetScout Arbor brand with a broad range of vendors including Radware, Akamai, Networks, A10 Networks, Fortinet, Fastly, Cloudflare and Corero Network Security. In the market for specialized threat analysis, packet forensics and protection solutions used to identify advanced network threats, we compete with a range of vendors including Darktrace, Vectra Networks, FireEye, Cisco, Palo Alto Networks, RSA and other specialist providers.
Our ability to sustain a competitive advantage depends on our ability to deliver continued technology innovation and adapt to meet the evolving needs of our customers. Competitive factors in our industry are further described in Item 1A "Risk Factors."
Intellectual Property Rights
We rely on patent, copyright, trademark, and trade secret laws and contract rights to establish and maintain our rights in our technology and products. While our intellectual property rights are an important element in our success, our business as a whole does not depend on any one particular patent, trademark, copyright, trade secret, license, or other intellectual property right.
We use contracts, statutory laws, domestic and foreign intellectual property registration processes, and international intellectual property treaties to police and protect our intellectual property portfolio and rights from infringement. From a contractual perspective, we use license agreements and non-disclosure agreements to control the use of our intellectual property and protect our trade secrets from unauthorized use and disclosure. In addition to license agreements, we rely on U.S. and international copyright law to protect against unauthorized copying of software programs in the U.S. and abroad. We have obtained U.S. and foreign trademark registrations to preserve and protect certain trademarks and trade names. We have also filed and obtained U.S. patents and international counterparts to protect certain unique NetScout inventions from being unlawfully exploited by other parties. However, there is no assurance that pending or future patent applications will be granted, that we will be able to obtain patents covering all of our products, or that we will be able to license, if needed, patents from other companies on favorable terms or at all. Our proprietary rights are subject to other risks and uncertainties described under Item 1A "Risk Factors."
Employees
As of March 31, 2021, we had 2,421 employees worldwide - over 99% of whom were full time employees. Our employees are in over 35 countries with 64% of our employees located in the United States.

Diversity, equity, and inclusion (DEI) are the cornerstones of our organizational excellence and complement our core values of performing with integrity, compassion, collaboration, and innovation. We embrace and encourage our employees' differences in age, color, disability, ethnicity, family or marital status, gender identity or expression, language, national origin, physical and mental ability, political affiliation, race, religion, sexual orientation, socio-economic status, veteran status, and other characteristics that make our employees unique. As such, we strive to demonstrate our commitment to DEI at the highest levels. Educating our employees about our DEI initiatives is a priority. In addition, we recently chartered a DEI team to ensure transparent and equitable processes for employee engagement, onboarding, learning and development, policy making, and career planning.
Culture & Values
We believe that our company culture is critical to our success and growth. Our culture complements and acts as a multiplier to our technology, exceptional talent, and forward-thinking innovation. As a result of our philosophy, we have pledged to be considerate, loyal and appreciative of our employees while also enacting decision-making processes and business strategies that result in efficient business outcomes.
We take seriously our mission as Guardians of the Connected World. We recently launched our internal NETSCOUT WITHOUT BORDERS initiative, of which a key component is an employee engagement program to continuously
communicate our mission and goals to all of our global employees through a series of town hall meetings that provide direct interaction with the CEO, in-depth focus groups, and follow-on development programs. This is a significant investment to stay connected with all employees, and to ensure everyone is equipped with the knowledge and tools and aligned with our mission.
COVID-19 Response
During the COVID-19 pandemic, our top priority has been the safety and well-being of our employees and their families to ensure that they continue to be productive and keep our customers and the world connected. As the severity and scope of the pandemic became known in early calendar year 2020, we curtailed travel and required all employees, in all locations, to work from home, with only a limited numbers of employees with business-critical tasks provided access to our facilities. For those employees who needed to be on-site, we established multiple protective measures to ensure the safety of our employees. Throughout the course of the COVID-19 pandemic, we were able to maintain our unique culture, support our employees with well-being programs and uninterrupted salary and benefits, and maintain our market presence and unfailingly superior service levels to our customers.

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors.
In addition to the other information in this report, the following factors should be considered carefully in evaluating NetScout and our business.
Our operating results and financial condition have varied in the past and may vary significantly in the future depending on a number of factors. Except for the historical information in this report, the matters contained in this report include forward-looking statements that involve risk and uncertainties. The following factors are among many that could cause actual results to differ materially from those contained in or implied by forward-looking statements made in this report. These statements involve the risks and uncertainties identified below as well as additional risks and uncertainties that are not yet identified or that we currently think are immaterial but may also impact our business operations. Such factors are among many that may have a material adverse impact upon our business, results of operations, liquidity, and financial condition.
You should carefully consider the risks and uncertainties described below, together with the information included elsewhere in this Annual Report on Form 10-K and other documents we file with the SEC. The risks and uncertainties described below are those that we have identified as material but are not the only risks and uncertainties facing us. Our business is also subject to general risks and uncertainties that affect many other companies. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial also may impair our business, including our results of operations, liquidity, and financial condition.
Because of the following factors, as well as other variables affecting our results of operations, past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods.
Summary of the Material Risks Associated with Our Business
These risks include, but are not limited to, the following:
•Our business and operations, and the operations of our customers, partners, and/or suppliers, may be adversely affected by epidemics and pandemics, such as the COVID-19 pandemic.
•Unfavorable conditions in our industry or the global economy, or reductions in information technology spending, could limit our ability to grow our business and negatively affect our results of operations.
•Potential product vulnerabilities or critical security defects, prioritization decisions regarding remedying vulnerabilities or security defects, or customers not deploying security releases or deciding not to upgrade products, services, or solutions could result in claims of liability against us, damage our reputation, or otherwise harm our business.
•If we or third parties who we work with experience a security incident, or the confidentiality, integrity, or availability of our information technology, software, services, communications or data is compromised, our business or platform may be perceived as not being secure, our reputation may be harmed, demand for our offering may be reduced, and we may incur significant liabilities.
•Our ability to quickly and successfully recover from a disaster, public health crisis (including a global pandemic such as the COVID-19 pandemic), or other business continuity event could affect our ability to deliver our products and negatively impact our business reputation.
•If our products contain errors or quality issues, such issues may be costly to correct, revenue may be delayed, we could be sued, and our reputation could be harmed.
•If we fail to introduce new products and solutions or enhance our existing products and solutions to keep up with rapid technological change, demand for our products and solutions may decline.
•Our success depends, in part, on our ability to manage our international research and development operations and related partnerships. Our international research and development efforts may achieve delayed or lower than expected benefits and involve competitive and other risks.
•Necessary licenses for third-party technology may not be available to us on commercially reasonable terms or at all.
•Increased customer demands on our technical support services may adversely affect our relationships with our customers and our financial results.
•The success of our business depends, in part, on the continued growth in the market for and the continued commercial demand for service delivery, service assurance and network security solutions focused on the performance monitoring and management of applications and networks.
•Failure to manage growth properly and to implement enhanced automated systems could adversely impact our business.
•Our growth could suffer if the markets into which we sell our products and services experience cyclicality.
•Our reliance on sole source suppliers could adversely impact our business.
•We or our suppliers may be affected by new regulations related to climate change or other environmental issues.
•Our success depends, in part, on our ability to manage and leverage our distribution channels. Disruptions to, or our failure to effectively develop and manage, these partners and the processes and procedures that support them could adversely affect our ability to generate revenues from the sale of our products and services.
•Our success depends on our ability to protect our intellectual property rights.
•Others may claim that we infringe on their intellectual property rights.
•Our indebtedness may limit our operations and our use of our cash flow, and any failure to comply with the covenants that apply to our indebtedness could adversely affect our liquidity and financial condition.
•Any failure to meet our debt obligations could damage our business.
•We may fail to secure necessary additional financing.
•The failure to recruit and retain qualified personnel and plan for and manage the succession of key executives could hinder our ability to successfully manage our business, which could have a material adverse effect on our financial position and operating results.
•We may not successfully complete acquisitions or integrate acquisitions we do make, which could impair our ability to compete and could harm our operating results.
•We face significant competition from other technology companies.
•Uncertainties of regulation of the Internet and data traveling over the Internet could have a material and adverse impact on our financial condition and results of operations.
•We are subject to stringent and changing laws, regulations, standards, contractual obligations, and other obligations related to privacy, data protection, and data security. The actual, alleged, or perceived failure by us or the partners we work with to comply with such obligations could adversely affect our business, results of operations, and financial conditions.
•Foreign currency exchange rates may adversely affect our financial statements.
•If we violate the U.S. Foreign Corrupt Practices Act or applicable anti-bribery laws in other countries, or if we fail to comply with U.S. export controls and government contracting laws, our business could be harmed.
•The current economic and geopolitical environment may impact some specific industries into which we sell and may lead our customers to delay or forgo technology investments and could have other impacts, any of which could materially adversely affect our business, financial condition, operating results and cash flows.
•International economic, political, legal, compliance and business factors could negatively affect our financial statements and growth.
The summary risk factors described above should be read together with the text of the full risk factors below and in the other information set forth in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes, as well as in other documents that we file with the SEC.
Risks Related to Our Business and Industry
Our business and operations, and the operations of our customers, partners, and/or suppliers, may be adversely affected by epidemics and pandemics, such as the COVID-19 pandemic. The COVID-19 pandemic and future epidemics and pandemics risk disrupting and adversely affecting our business operations and financial results, as well as the markets and communities in which we and our customers, suppliers and other business partners operate.
We face risks related to epidemics, pandemics, and other outbreaks of communicable diseases that adversely affect global commercial activity, economies, financial markets, and companies. The outbreak of COVID-19 was declared a "pandemic" by the World Health Organization on March 11, 2020. An epidemic or pandemic or other outbreak of communicable diseases, such as the current COVID-19 pandemic, poses the risk that we or our customers, suppliers, and other business partners may be disrupted or prevented from conducting normal business activities for certain periods of time, the durations of which are uncertain, and may otherwise experience significant impairments of business activities.
In response to the COVID-19 pandemic, many state, local, and foreign governments have put in place, and others in the future may put in place or continue, quarantines, executive orders, shelter-in-place orders, and similar government orders and restrictions to reduce the rate of infection and control the spread of the disease. Such orders or restrictions, or the perception that such orders or restrictions could occur, may continue to result in business closures, work stoppages, slowdowns and delays, travel restrictions and cancellation of events, among other effects that could affect productivity and disrupt our operations and those of our suppliers, customers, and business partners.
To protect our employees, contractors, customers, suppliers, and our local communities, and limit the effect of the COVID-19 pandemic on our operations, many of our employees at our locations globally have been working remotely for the past year, with limited exceptions for site-essential personnel (with protective measures and protocols in place). We may take further actions that alter our operations as may be required by federal, state, or local authorities, or by foreign governments in countries in which we operate, or which we determine are in the best interests of our employees, suppliers, customers, business partners, and stockholders. We expect that work-from-home requirements and other restrictions on our employees, suppliers, customers, and business partners will change over time, whether becoming more or less restrictive, as the pandemic and global responses progress.
There continues to be uncertainty as to when all of our employees will be able to return to work on-site. Similar to other companies, we have begun planning for our employees to return to work on-site in phases, in accordance with federal, state, and local government guidelines, as well as in accordance with foreign government guidelines in the countries in which we operate. Furthermore, any process we implement to enable our employees to return to work on-site will be in accordance with prevailing health and science guidance, and in a manner that seeks to protect our employees, contractors, customers, suppliers, and our local communities.
As part of our existing business continuity planning, we had established infrastructure and protocols to enable our employees to work from home. While we believe that the majority of our employees are able to and can continue to effectively work remotely, it is possible that disruptions to our business operations resulting from quarantines, self-isolations, or other movement and restrictions on the ability of our employees to perform their jobs could affect our ability to develop and design our products and services in a timely manner or meet required milestones or customer commitments, and that this could have an adverse effect on our revenue and operating results. In addition, although we have been able to adequately staff our facilities with site-critical personnel with specific health and safety protocols, to satisfy our manufacturing and support obligations to our
customers, it is possible that we or others may determine that it is necessary to direct that employees engaged in manufacturing and support refrain from working on-site for an indeterminate period of time, and that this could have an adverse effect on our revenue and operating results.
Furthermore, global travel has been sharply curtailed, and in some cases prohibited. Our sales personnel often meet with customers or prospective customers in person to provide greater personalized service. While our employees and customers have adjusted to virtual meetings, the inability of our sales personnel to meet with customers or prospective customers at a customer facility could have an adverse effect on our revenue and operating results.
In addition, we rely on third-party suppliers and manufacturers throughout the globe. The COVID-19 pandemic has resulted in the extended shutdown of certain businesses and the closure of international borders throughout the world, which may result in disruptions to our supply chain. These may include disruptions from temporary closure of third-party supplier and manufacturer facilities, interruptions in product supply or restrictions on the export or shipment of our products, as well as the import of products into countries in which we operate. Although we have attempted to minimize the effects of these disruptions, it is possible that these attempts will be insufficient, and that these disruptions will likely have an adverse effect on our revenues and operating results.
To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this "Risk Factors" section, such as those relating to our quarterly revenue and operating results, the estimates made for our critical accounting policies, and the operation of internal controls over such estimates, as well as on our liquidity and on our ability to satisfy our indebtedness obligations, including the compliance with the covenants that apply to our indebtedness.
Unfavorable conditions in our industry or the global economy, or reductions in information technology spending, could limit our ability to grow our business and negatively affect our results of operations.
Our results of operations may vary based on the impact of unfavorable changes in our industry or the global economy on us or our customers and potential customers. Unfavorable conditions in the economy both in the United States and abroad, including conditions resulting from financial and credit market fluctuations, international trade relations, political turmoil, natural catastrophes, outbreaks of contagious diseases (such as the ongoing COVID-19 pandemic), warfare and terrorist attacks on the United States, Europe, the Asia Pacific region or elsewhere, could cause a decrease in business investments, including spending on information technology, disrupt the timing and cadence of key industry events, and negatively affect the growth of our business and our results of operations. For example, these types of unfavorable conditions could disrupt the timing of and attendance at key industry events, which we rely upon in part to generate sales of our products. If those events are disrupted, our marketing investments, sales pipeline, and ability to generate new customers and sales of our products could be negatively and adversely affected. In addition, our competitors, many of whom are larger and have greater financial resources than we do, may respond to challenging market conditions by lowering prices in an attempt to attract our customers and may be less dependent on key industry events to generate sales for their products. In addition, the increased pace of consolidation in certain industries may result in reduced overall spending on our products and solutions. We cannot predict the timing, strength, or duration of any economic slowdown, instability, or recovery, generally or how any such event may impact our business.
Potential product vulnerabilities or critical security defects, prioritization decisions regarding remedying vulnerabilities or security defects, or customers not deploying security releases or deciding not to upgrade products, services, or solutions could result in claims of liability against us, damage our reputation, or otherwise harm our business.
The products and services we sell to customers, and our cloud-based solutions, may contain vulnerabilities or critical security defects which have not been identified or remedied. We may also make prioritization decisions in determining which vulnerabilities or security defects to fix, and the timing of these fixes, which could result in an exploit that compromises security.
Customers also sometimes need to test security releases before they can be deployed, which can delay implementation. In addition, we rely on third-party providers of software and cloud-based services, and we cannot control the rate at which they remedy vulnerabilities. Customers may also not deploy a security release or decide not to upgrade to the latest versions of our products, services, or cloud-based solutions containing the release, leaving them vulnerable.
If we or third parties who we work with experience a security incident, or the confidentiality, integrity, or availability of our information technology, software, services, communications or data is compromised, our business or platform may be perceived as not being secure, our reputation may be harmed, demand for our offering may be reduced, and we may incur significant liabilities.
In the regular course of our business, we collect, use, store, transmit and process data, which can include information about our customers, employees, and others and which may be sensitive, proprietary, or confidential. Security incidents compromising the confidentiality, integrity, and availability of this information or our systems could result from a wide variety of cyberattacks, computer malware, viruses, social engineering (including phishing), ransomware, supply chain attacks, credential stuffing, efforts by individuals or groups of hackers and sophisticated organizations, including state-sponsored organizations, errors or malfeasance of our personnel, security vulnerabilities in the software or systems on which we rely, cyber extortion, and denial of service attacks. Such incidents have become more prevalent in our industry, and may in the future result in the unauthorized, unlawful, or inappropriate access to, inability to access, disclosure of, or loss of the sensitive, proprietary, and confidential information that we handle. Additionally, due to the ongoing COVID-19 pandemic, certain functional areas of our workforce remain in a remote work environment and outside of our corporate network security protection boundaries, which imposes additional risks to our business, including increased risk of industrial espionage, phishing, and other cybersecurity attacks, and unauthorized dissemination of sensitive, proprietary, or confidential information.
We also rely on third parties to operate our business systems and process the sensitive, proprietary, and confidential information that we handle. These third parties may not have adequate security measures and could experience a security incident that compromises the confidentiality, integrity, or availability of the systems they operate for us or the information they process on our behalf. Cybercrime and hacking techniques are constantly evolving, and we or third parties who we work with may be unable to anticipate attempted security breaches, react in a timely manner, or implement adequate preventative measures, particularly given increasing use of hacking techniques designed to circumvent controls, avoid detection, and remove or hide forensic information.
Although we have multiple and layered controls and security measures in place designed to prevent cyberattacks, experienced computer hackers are increasingly organized and sophisticated and we cannot guarantee that our, or our third-party partners’ security measures will be sufficient to protect against unauthorized access to our IT networks, software and systems. Malicious attack efforts operate on a large-scale and sometimes offer targeted attacks as a paid-for service. In addition, the techniques used to obtain access or sabotage networks change frequently and we may be unable to anticipate such techniques, implement adequate preventative measures, or stop security breaches that may arise from such techniques. As a provider of security solutions, we may be a more attractive target for such attacks. Other individuals or entities, including personnel or vendors, may also intentionally or unintentionally provide unauthorized access to our IT environments.
If we or the third-parties who we work with were to experience a security incident or other incident that results in the compromise of the confidentiality, integrity, or availability of our sensitive or the sensitive, proprietary, or confidential information we process, we or our customers may experience system disruptions or slowdowns, security vulnerabilities of our products could be exploited, the information stored on our networks or those of our third-party service providers or partners could be accessed, publicly disclosed, misappropriated, deleted, altered, lost, or stolen, all of which could subject us to liability and cause us financial harm. Any actual, alleged or perceived security breach or incident affecting us, our partners or our industry as a whole could result in damage to our reputation, negative publicity, loss of partners, customers and sales, increased costs to remedy any problems and otherwise respond to any incident, regulatory investigations and enforcement actions, costly litigation, and other liability. In addition, we could incur substantial costs and liabilities, including but not limited to, expenses attributable to investigating, remediating and rectifying a security breach, cyberattack or other incident (including the cost of repairing any damage to our or our customers' systems or restoring data from backups), liability for stolen assets or information, lost revenue and income resulting from any system or product downtime, increased costs for cybersecurity protection, and costs to comply with any notification obligations resulting from any security incidents (including notifying affected individuals or relevant regulatory authorities). Such outcomes could damage our reputation, cause customers and possibly investors to lose confidence in us, and adversely affect our business or operating results.
Additionally, efforts by hackers or others could cause interruptions, delays or cessation of our product licensing, or modification of our software, which could cause us to lose existing or potential customers. If these efforts are successful and a third party obtains unauthorized access to our or our customers' IT environments, our business operations, and those of our customers could be adversely affected, losses or theft of data could occur, our reputation and future sales could be harmed, governmental regulatory action or private or governmental litigation could be commenced against us and our business, and our financial condition, operating results and cash flows could be materially adversely affected.
We are required to comply with laws, rules, industry standards, and regulations that require us to maintain the security of personal information. We may also have contractual and other legal obligations to notify relevant stakeholders of security incidents. Such notifications are costly, could lead to negative publicity, may cause our customers to lose confidence in the effectiveness of our security measures and not use our services, and require us to expend significant capital and other resources to respond to and/or alleviate problems caused by the actual, alleged or perceived security incident.
Our ability to quickly and successfully recover from a disaster, public health crisis (including a global pandemic such as the COVID-19 pandemic), or other business continuity event could affect our ability to deliver our products and negatively impact our business reputation.
The occurrence of a natural disaster, public health crisis (including a global pandemic such as the COVID-19 pandemic) or an act of terrorism, or a decision or need to close any of our facilities without adequate notice or time for making alternative arrangements could result in interruptions in the delivery of our products and services. Our central business functions, including administration, human resources, finance services, legal, development, manufacturing and customer support depend on the proper functioning of our computer, telecommunication and other technology systems and operations, some of which are operated or hosted by third parties.
While we have business continuity programs in place, a disruption or failure of these systems or operations because of a disaster, public health crisis (including a global pandemic such as the COVID-19 pandemic) or other business continuity event could cause data to be lost or otherwise delay our ability to complete sales and provide the highest level of service to our customers. In addition, we could have difficulty producing accurate financial statements on a timely basis, which could have an impact on our ability to make timely disclosures and could adversely affect the trading value of our stock. Although we endeavor to ensure there is redundancy in these systems and that they are regularly backed-up, there are no assurances that data recovery in the event of a disaster would be effective or occur in an efficient manner. Our operations are dependent upon our ability to protect our technology infrastructure against damage from business continuity events that could have a significant disruptive effect on our operations. We could experience material adverse interruptions to our operations or delivery of services to our clients in a disaster recovery scenario.
If our products contain errors or quality issues, such issues may be costly to correct, revenue may be delayed, we could be sued, and our reputation could be harmed.
Our products are inherently complex, and, despite our quality assurance processes and testing by our customers and us, errors or quality issues may be found in our products after commencement of commercial shipments, especially when products are first introduced or when new versions are released. These errors may result from components supplied by third parties incorporated into our products, which makes us dependent upon the cooperation and expertise of such third parties for the diagnosis and correction of such errors. If errors are discovered, we may not be able to correct them in a timely manner or at all. In addition, we may need to make significant expenditures to eliminate errors and failures. Errors and failures in our products could result in loss of or delay in market acceptance of our products and could damage our reputation. Regardless of the source of these defects or errors, we may need to divert the attention of our engineering personnel from our product development efforts to address the detection and correction of these errors and defects. If one or more of our products fail, a customer may assert warranty and other contractual claims for substantial damages against us. Our contracts with customers contain provisions relating to warranty disclaimers and liability limitations, which may not be upheld. Defending a lawsuit, regardless of its merit, is costly and may divert management's attention and harm the market's perception of us and our products. In addition, if our business liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business, operating results, and financial condition could be adversely impacted.
The occurrence or discovery of these types of errors or failures could have a material and adverse impact on our business, operating results, and financial condition. Any such errors, defects, or security vulnerabilities could also adversely affect the market's perception of our products and business.
If we fail to introduce new products and solutions or enhance our existing products and solutions to keep up with rapid technological change, demand for our products and solutions may decline.
The market for application and network performance management, service assurance, cybersecurity solutions, and business intelligence is highly competitive and characterized by rapid changes in technology, evolving industry standards, changes in customer requirements, a current high level of and increasing competition, and frequent product introductions and enhancements. Our success is dependent upon our ability to meet our customers' needs, which are driven by changes in technologies, new application technologies, new security risks and the emergence of new industry standards. In addition, new technologies may shorten the life cycle for our products and solutions or could render our existing or planned products and services less competitive or obsolete. We must address demand from our customers for advancements in our products and services applications to support our customers' growing needs and requirements. To meet this challenge and remain competitive in the market, we must introduce new enhancements and additional form factors to our existing product lines and service offerings. If we are unable to develop, introduce and communicate new network and application performance management and service assurance products, network security products, business intelligence products, and solutions or enhancements to existing
products in a timely and successful manner, this inability could have a material and adverse impact on our business, operating results and financial condition.
As our success depends in part on our ability to develop product enhancements and new products and solutions that keep pace with continuing changes in technology, cyber risk and customer preferences, we must devote significant resources to research and development, development and introduction of new products and enhancements on a timely basis, and obtaining market acceptance for our existing products and new products. We have introduced and intend to continue to introduce new products and solutions, including increased migration to "software as a service" and software-deployed products as well as cybersecurity products. If the introduction of these products and solutions is significantly delayed or if we are unsuccessful in bringing these products and solutions to market, our business, operating results, and financial condition could be materially and adversely impacted. We are developing and are already deploying a number of new products as well as enhancements to our existing products and offerings, including software only solutions and products available in multiple form factors.
We must invest in research and development to remain competitive in our industry. However, there can be no assurances that continued investment and increased research and development expenses will ultimately result in our maintaining or increasing our market share, which could result in a decline in our operating results. The process of developing new solutions is complex and uncertain; we must commit significant resources to developing new services or features without knowing whether our investments will result in services or features the market will accept. If our research and development expenses increase without a corresponding increase in our revenues, it could have a material adverse effect on our operating results. Also, we may not be able to successfully complete the development and market introduction of new products or product enhancements in a timely manner. If we fail to develop and deploy new products and product enhancements on a timely basis, or if we fail to gain market acceptance of our new products, our revenues will likely decline, and we may lose market share to our competitors.
Our success depends, in part, on our ability to manage our international research and development operations and related partnerships. Our international research and development efforts may achieve delayed or lower than expected benefits and involve competitive and other risks.
We must continue to enhance our existing products and introduce new products to keep up with rapid technological change. Our international research and development teams play a critical role in these efforts. We must attract, train, motivate and retain our international research and development team members. To maintain this international employee research and development talent, we believe we must provide our international engineers with compelling and strategically significant work, coupled with technical and architectural ownership of their respective development projects. We must develop the leaders of these international teams, while ensuring their frequent inclusion and participation in corporate strategic and operational planning. We are likely to recognize the costs associated with these investments earlier than some of the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect. These development efforts also involve risks, including, knowledge transfer issues related to our technology and resulting exposure to misappropriation of intellectual property or information that is proprietary to us, heightened exposure to economic, security and political conditions abroad, and exchange rate and tax compliance issues. The risks related to our research and development efforts abroad could increase our expenses, impair our development efforts, harm our competitive position, and damage our reputation. If we do not achieve the benefits anticipated from these investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected.
Necessary licenses for third-party technology may not be available to us on commercially reasonable terms or at all.
We currently and will in the future license technology from third parties that we use to produce or embed in our products. While we have generally been able to license required third-party technology to date, third-party licenses required in the future may not be available to us on commercially reasonable terms or at all. Third parties who hold exclusive rights to technology that we seek to license may include our competitors. If we are unable to obtain any necessary third-party licenses, we would be required to redesign our product or obtain substitute technology, which may not perform as well, be of lower quality or be more costly. The loss of these licenses or the inability to maintain any of them on commercially acceptable terms could delay development of future products or the enhancement of existing products. We may also choose to pay a premium price for such a license in certain circumstances where continuity of the licensed product would outweigh the premium cost of the license. The unavailability of these licenses or the necessity of agreeing to commercially unreasonable terms for such licenses could materially adversely affect our business, financial condition, operating results, and cash flows.
Increased customer demands on our technical support services may adversely affect our relationships with our customers and our financial results.
We offer technical support services with many of our products. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support services. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. Our customers depend on our support organization to resolve issues relating to our products deployed on their networks. A high level of support is critical for continued relationships with our customers. If we or our channel partners do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective ongoing support, it would adversely affect our ability to sell our products to existing customers and would harm our reputation with existing and potential customers. Any failure to maintain high quality support and services would harm our operating results and reputation. Further, if customers demand these services, and we cannot adequately meet their demand, or if we cannot realize revenues in connection with our provision of services related to product support, it could have a material and adverse impact on our financial condition and results of operations.
The success of our business depends, in part, on the continued growth in the market for and the continued commercial demand for service delivery, service assurance and network security solutions focused on the performance monitoring and management of applications and networks.
We derive nearly all our revenue from the sale of products and services that are designed to allow our customers to assure the delivery of services through management of the performance and network security of applications across IP networks. We have actively expanded our operations in the past through acquisitions and organic growth and may continue to expand them in the future to gain share in the evolving market in which we operate. Therefore, we must be able to predict the appropriate features and prices for future products to address the market, the optimal distribution strategy, and the future changes to the competitive environment. For us to be successful, our potential customers must recognize the value of more sophisticated application management and network security solutions, decide to invest in the management of their networked applications and, in particular, adopt our management solutions. Any failure of this market to continue to be viable would materially and adversely impact our business, operating results, and financial condition. Additionally, businesses may choose to outsource the operations and management of their networks to managed service providers. Our business may depend on our ability to continue to develop relationships with these service providers and successfully market our products to them.
Failure to manage growth properly and to implement enhanced automated systems could adversely impact our business.
The growth in size and complexity of our business and our customer base has been and will continue to be a challenge to our management and operations. Additional growth will place significant demands on our management, infrastructure, and other resources. To manage further growth effectively, we must hire, integrate, and retain highly skilled personnel qualified to manage our expanded operations. We will also need to continue to improve our financial and management controls, reporting systems, and procedures. If we are unable to manage our growth effectively, our costs, the quality of our products, the effectiveness of our sales organization, attraction and retention of key personnel, our business, our operating results and financial condition could be materially and adversely impacted. To manage our growth effectively, we may need to implement new or enhanced automated infrastructure technology and systems.
Any disruptions or ineffectiveness relating to our systems implementations and enhancements could adversely affect our ability to process customer orders, ship products, provide services and support to our customers, bill and track our customers, fulfill contractual obligations, and otherwise run our business.
As a result of the diversification of our business, personnel growth, acquisitions, and international expansion in recent years, most of our employees are based outside of our headquarters. If we are unable to appropriately increase management depth and enhance succession planning, we may not be able to achieve our financial or operational goals. It is also important to our continued success that we hire qualified employees, properly train them and manage out poorly performing personnel, all while maintaining our corporate culture and spirit of innovation. If we are not successful at these efforts, our growth and operations could be adversely affected.
As our business evolves, we must also expand and adapt our information technology (IT) and operational infrastructure. Our business relies on our data systems, billing systems and other operational and financial reporting and control systems. All these systems have become increasingly complex due to the diversification and complexity of our business and acquisitions of new businesses with different systems. To manage our technical support infrastructure effectively and improve our sales efficiency, we will need to continue to upgrade and improve our data systems, billing systems, ordering processes, customer relationship management systems, and other operational and financial systems, procedures and controls. These upgrades and improvements may be difficult and costly, and they may require employees to dedicate a significant amount of time to implement. If we are unable to adapt our systems and organization in a timely, efficient, and cost-effective manner to
accommodate changing circumstances, our business may be adversely affected. If the third parties we rely on for hosted data solutions for our internal network and information systems are subject to a security breach or otherwise suffer disruptions that impact the services we utilize, the integrity and availability of our internal information could be compromised causing the loss of confidential or proprietary information, damage to our reputation and economic loss.
Our growth could suffer if the markets into which we sell our products and services experience cyclicality.
Our growth will depend in part on the growth of the markets which we serve. We serve certain industries that have historically been cyclical and have experienced periodic downturns that have had a material adverse impact on demand for the products, software, and services that we offer. Any of these factors could adversely affect the business, financial condition, and results of operations of the company in any given period.
Our reliance on sole source suppliers could adversely impact our business.
Specific components that are necessary for the hardware assembly of our instruments are obtained from separate sole source suppliers or a limited group of suppliers. These components include our network interface cards and proprietary hardware. Our reliance on sole or limited suppliers involves several risks, including a lack of control over the manufacturing process and inventory management and potential inability to obtain an adequate supply of required components and the inability to exercise control over pricing, quality and timely delivery of components. For most of our products, we do not have the internal manufacturing capabilities to meet our customers' demands. It is our practice to mitigate these risks by partnering with key suppliers, including distributors, to establish a variety of supply continuity practices. These practices may include, among other approaches, establishing buffer supply requiring suppliers to maintain adequate stocks of materials, bonding agreements with distributors, and use-based and kanban programs to set supply thresholds. We also enter into escrow arrangements for certain technologies. Where possible, we use widely available off the shelf hardware and work with large suppliers with multiple factories and other risk management practices. However, failure of supply or failure to execute effectively on any of these programs, including as a result of a public health crisis (included a global pandemic such as the COVID-19 pandemic) could result in our inability to obtain adequate deliveries or the occurrence of any other circumstance that would require us to seek alternative sources of supply for these components would impact our ability to ship our products on a timely basis. Moreover, if we are unable to continue to acquire from these suppliers on acceptable terms, or should any of these suppliers cease to supply us with components for any reason, we may not be able to identify and integrate an alternative source of supply in a timely fashion or at the same costs. Any transition to one or more alternate manufacturers would likely result in delays, operational problems, and increased costs, and may limit our ability to deliver our products to our customers on time for such transition period. These risks could damage relationships with our current and prospective customers, cause shortfalls in expected revenue, and could materially and adversely impact our business, operating results and financial condition.
We or our suppliers may be affected by new regulations related to climate change and other environmental issues.
We or our suppliers may become subject to new laws enacted with regards to climate change and other environmental issues. If new laws are enacted, or current laws are modified in countries in which we or our suppliers operate, we could face increased costs to comply with these laws. These costs may be incurred across various levels of our supply chain to comply with new environmental regulations, as well as by us in connection with our manufacturing of products, including costs related to incorporation of substitute materials and other product re-design costs, as well as costs associated with product recalls. In addition, we may be unable to service existing products if certain materials are no longer compliant with new regulations, which could cause us to incur increased costs to satisfy service obligations to customers. Additionally, our flow of product may be impacted which could delay the recognition of revenue and have a materially adverse effect on our business.
Our success depends, in part, on our ability to manage and leverage our distribution channels. Disruptions to, or our failure to effectively develop and manage, these partners and the processes and procedures that support them could adversely affect our ability to generate revenues from the sale of our products and services. Managing these distribution channels and relationships requires experienced personnel, and lack of sufficient expertise could lead to a decrease in sales of our products and services, which could cause our operating results to suffer.
Our future success may require us to increase the number and use of our indirect sales efforts through our distributors and channel partners and to leverage those relationships to expand these our distribution channels and to develop new indirect distribution channels to increase revenue. Our channel partners have no obligation to purchase any products from us. Some of our distribution and channel partners also distribute and sell competitive products and services and the reduction in sales by these partners could materially reduce our revenues. In addition, they could internally develop products that compete with our solutions or partner with our competitors and bundle or resell competitors' solutions, possibly at lower prices. The potential
inability to develop relationships with new partners in new markets, expand and manage our existing partner relationships, the unwillingness of our partners to market and sell our products effectively or the loss of existing partnerships could have a material and adverse impact on our business, operating results and financial condition. Our international operations, including our operations in the United Kingdom, mainland Europe, India, Asia-Pacific and other regions, are generally also subject to the risk of longer sales cycles through our international distribution channels. Sales to customers outside the United States accounted for 42%, 39%, and 39% of our total revenue for the fiscal years ended March 31, 2021, 2020 and 2019, respectively.
The need to develop such relationships can be particularly acute in areas outside of the U.S. Recruiting and retaining qualified channel partners and training them in the use of our technology and services and ensuring that they comply with our legal and ethical requirements requires significant time and resources throughout the relationship.
Risks Related to Our Intellectual Property
Our success depends on our ability to protect our intellectual property rights.
Our business is heavily dependent on our intellectual property. We rely upon a combination of patent, copyright, trademark and trade secret laws and registrations and non-disclosure and other contractual and license arrangements to protect our intellectual property rights. The reverse engineering, unauthorized copying, or other misappropriation of our intellectual property could enable third parties to benefit from our technology without compensating us. Furthermore, the laws of some foreign jurisdictions do not offer the same protections for our proprietary rights as the laws of the United States, and we may be subject to unauthorized use of our products in those countries. Legal proceedings to enforce our intellectual property rights could be burdensome and expensive and could involve a high degree of uncertainty. In addition, legal proceedings may divert management's attention from growing our business. There can be no assurance that the steps we have taken to protect our intellectual property rights will be adequate to deter misappropriation of proprietary information, or that we will be able to detect unauthorized use by third parties and take appropriate steps to enforce our intellectual property rights. The unauthorized copying or use of our products or proprietary information could result in reduced sales of our products and eventually harm our operating results.
Others may claim that we infringe on their intellectual property rights.
We are and may continue to be subject to claims by others, whether valid or not, that our products infringe on their intellectual property rights, patents, copyrights, or trademarks. These claims, whether or not valid, could require us to spend significant sums in litigation, pay damages or royalties, delay product shipments, reengineer our products, rename our products and rebuild name recognition or acquire licenses to such third-party intellectual property. We may not be able to secure any required licenses on commercially reasonable terms or secure them at all. In some cases, we may have agreed to contract terms that indemnify our customers and partners if our products or technology infringe or misappropriate specified third party intellectual property rights; therefore, we could become involved in litigation or claims brought against our customers or partners if our products or technology are the subject of such allegations. Any of these claims or resulting events could have a material and adverse impact on our business, operating results, and financial condition.
Risks Related to Our Liquidity and Financial Condition
Our indebtedness may limit our operations and our use of our cash flow, and any failure to comply with the covenants that apply to our indebtedness could adversely affect our liquidity and financial condition.
On January 16, 2018, we amended and expanded our existing credit facility (Amended Credit Agreement) with a syndicate of lenders. The Amended Credit Agreement provides for a five-year $1.0 billion senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. We have used the new credit facility for working capital purposes and to finance the repurchase of common stock under a previous accelerated stock repurchase plan. The commitments under the Amended Credit Agreement will expire on January 16, 2023, and any outstanding loans will be due on that date. As of the date of this report, we had approximately $350 million in outstanding indebtedness under the Amended Credit Agreement. Our debt level can have negative consequences, including exposing us to future interest rate risk. We may incur significantly more debt in the future, and there can be no assurance that our cost of funding will not substantially increase. Our current revolving credit facility also imposes certain restrictions on us; for a more detailed description please refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations." Upon an event of default, for example, the administrative agent, with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments, may terminate the commitments and accelerate the maturity of the loans outstanding under the
Amended Credit Agreement and enforce certain other remedies under the Amended Credit Agreement and other loan documents, which would adversely affect our liquidity and financial condition. If we take on additional indebtedness, the risks described above could increase.
Interest on the outstanding balances under the Amended Credit Agreement is calculated based on the London Interbank Offered Rate (LIBOR). On July 27, 2017, the U.K. Financial Conduct Authority (FCA), which regulates LIBOR, announced that it will no longer require banks to submit rates for the calculation of LIBOR after 2021. Further, on March 5, 2021, the Intercontinental Exchange Benchmark Administration, the FCA-regulated and authorized administrator of LIBOR, announced, and the FCA confirmed, that one week and two-month USD LIBOR settings will cease on December 31, 2021, and that the USD LIBOR panel for all other tenors will cease on June 30, 2023. The Amended Credit Agreement, which matures on January 16, 2023, prior to the cessation of USD LIBOR publications on June 30, 2023, provides a mechanism pursuant to which we and the administrative agent may agree, under certain circumstances, to transition to an alternate base rate borrowing or amend the credit agreement to establish an alternate interest rate to LIBOR that includes consideration of the then-prevailing market convention for determining interest rates for syndicated loans in the United States at that time.
If the methods of calculating LIBOR change from current methods for any reason, or if LIBOR ceases to perform as it has historically, or if we select an alternative benchmark rate our interest expense associated with our outstanding indebtedness or any future indebtedness we incur may increase.
Any failure to meet our debt obligations could damage our business.
Our ability to meet our obligations under the Amended Credit Agreement will depend on market conditions and our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. If we are unable to remain profitable, or if we use more cash than we generate in the future, our level of indebtedness at such time could adversely affect our operations by limiting or prohibiting our ability to obtain financing for additional capital expenditures, acquisitions and general corporate and other purposes. In addition, if we are unable to make payments as required under the Amended Credit Agreement, we would be in default under the terms of the loans, which could seriously harm our business. If we incur significantly more debt, this could intensify the risks described above.
We may fail to secure necessary additional financing.
Our future success may depend in part on our ability to obtain additional financing to support our continued growth and operations and any downgrades in our credit rating could affect our ability to obtain additional financing in the future or may affect the terms of any such financing. If our existing sources of liquidity are insufficient to satisfy our operating requirements, we may need to seek to raise capital by one or more of the following:
•issuing additional common stock or other equity instruments;
•acquiring additional bank debt;
•issuing debt securities; or
•obtaining lease financings.
However, we may not be able to obtain additional capital when we want or need it, or capital may not be available on satisfactory terms. Furthermore, any additional capital may have terms and conditions that adversely affect our business, such as new financial or operating covenants, or that may result in dilution to our stockholders.
We expect that existing cash, cash equivalents, marketable securities, cash provided from operations and our bank credit facilities will be sufficient to meet ongoing cash requirements. However, our failure to generate sufficient cash as our debt becomes due or to renew credit lines prior to their expiration could materially adversely affect our business, financial condition, operating results, and cash flows.
Other Risks Related to Our Business
The failure to recruit and retain qualified personnel and plan for and manage the succession of key executives could hinder our ability to successfully manage our business, which could have a material adverse effect on our financial position and operating results.
We operate in businesses where there is intense competition for experienced personnel in all our global markets and have, in some instances, experienced attrition of our employees to direct and indirect competitors. We depend on our ability to identify, recruit, hire, train, develop and retain qualified and effective professionals and to attract and retain talent needed to execute our business strategy. Our future success depends in large part upon our ability to attract, train, motivate and retain
highly skilled employees, particularly executives, sales and marketing personnel, software engineers, and technical support personnel. The complexity of our products, processing functionality, software systems and services require highly trained professionals. While we presently have a sophisticated, dedicated and experienced team of employees who have a deep understanding of our business lines, the labor market for these individuals has historically been very competitive due to the limited number of people available with the necessary technical skills and understanding. If we are unable to attract and retain the highly skilled technical personnel that are integral to our sales, marketing, product development and technical support teams, the rate at which we can generate sales and develop new products or product enhancements may be limited. This inability could have a material and adverse impact on our business, operating results, and financial condition.
In addition, we must maintain and periodically increase the size of our sales force in order to increase our direct sales and support our indirect sales channels. Because our products are very technical, salespeople require a comparatively long period of time to become productive, typically three to twelve months. This lag in productivity, as well as the challenge of attracting qualified candidates, may make it difficult to meet our sales force growth targets. Further, we may not generate sufficient sales to offset the increased expense resulting from growing our sales force. If we are unable to maintain and periodically expand our sales capability, our business, operating results and financial condition could be materially and adversely impacted.
Loss of key personnel could adversely impact our business. Our future success depends to a significant degree on the skills, experience and efforts of Anil Singhal, our President, Chief Executive Officer, and co-founder, and our other key executive officers and senior managers to work effectively as a team. Effective succession planning is also important for our long-term success. Failure to ensure effective transfers of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution. The loss of one or more of our key personnel could have a material and adverse impact on our business, operating results, and financial condition. We must, therefore, plan for and manage the succession of key executives due to retirement, illness, or competitive offers elsewhere.
We may not successfully complete acquisitions or integrate acquisitions we do make, which could impair our ability to compete and could harm our operating results.
We may need to acquire complementary businesses, products, or technologies to remain competitive or expand our business. We investigate and evaluate potential acquisitions of complementary businesses, products, and technologies in the ordinary course of business. We may compete for acquisition opportunities with entities having significantly greater resources than we have. As a result, we may not succeed in acquiring some or all businesses, products, or technologies that we seek to acquire. Our inability to effectively consummate acquisitions on favorable terms could significantly impact our ability to compete effectively in our targeted markets and could negatively affect our results of operations.
Acquisitions that we do complete could adversely impact our business. The potential adverse consequences from acquisitions include:
•the potentially dilutive issuance of common stock or other equity instruments;
•the incurrence of debt and amortization expenses related to acquired intangible assets;
•the potential litigation or other claims in connection with, an acquisition;
•the incurrence of significant costs and expenses to complete the acquisition and integrate the acquired business; and
•the potentially negative impact of poor performance of an acquisition on our earnings per share.
Acquisition transactions also involve numerous business risks. These risks from acquisitions include:
•difficulties in assimilating the acquired operations, technologies, personnel and products;
•difficulties in assimilating diverse financial reporting and management information systems as well as differing ordering processes and customer relationship management systems;
•use of cash to pay for acquisitions that may limit other potential uses of our cash, including stock repurchases and repayment of outstanding indebtedness;
•substantial accounting charges for restructuring and related expenses, write-off of in-process research and development, impairment of goodwill, amortization or impairment of intangible assets and share-based compensation expense;
•the potential loss of key employees, customers, distributors or suppliers; and
•the inability to generate sufficient revenue to offset acquisition or investment costs.
If we are not able to successfully manage these issues, the anticipated benefits and efficiencies of the acquisitions may not be realized fully or at all, or may take longer to realize than expected, and our ability to compete, our revenue and gross margins and our results of operations may be adversely affected.
We face significant competition from other technology companies.
The service assurance, application performance management, network security and business intelligence markets are highly competitive, rapidly evolving, and fragmented markets that have overlapping technologies and competitors, both large and small, and we expect competition on solutions offerings and pricing to increase. We believe customers make service management system, network security and business intelligence purchasing decisions based primarily upon the following factors:
•product and service performance, functionality and price;
•timeliness of new product and service introductions;
•network capacity;
•ease of installation, integration, and use;
•customer service and technical support;
•name and reputation of vendor;
•quality and value of the product and services; and
•alliances with industry partners.
We compete with a large and growing number of providers of service assurance, application performance management solutions, network security offerings and network traffic analyzers and probes, as well as with providers of business intelligence services. In addition, leading network equipment, network security and service assurance and application technology vendors offer their own management solutions, including products which they license from other competitors. Some of our current and potential competitors have greater name recognition and substantially greater financial, management, marketing, service, support, technical, distribution and other resources than we do. In addition, some of our customers develop their own in-house solutions to meet their technological needs. Further, in recent years some of our competitors have been acquired by larger companies that are seeking to enter or expand in the markets in which we operate. We expect this trend to continue as companies attempt to strengthen or maintain their market positions in an evolving industry. Therefore, given their larger size and greater resources, our competitors may be able to respond more effectively than we can to new or changing opportunities, technologies, standards and customer requirements.
As a result of the competitive factors highlighted in this section and in other risk factors, including the introduction of disruptive technologies, we may not be able to compete effectively with our current or future competitors. If we are unable to anticipate or react to these competitive challenges or if existing or new competitors gain market share in any of our markets, our competitive position could weaken and we could experience a decline in our sales that could adversely affect our business and operating results. This competition could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses, and failure to increase, or the loss of market share, any of which would likely have a material and adverse impact on our business, operating results and financial condition.
Uncertainties of regulation of the Internet and data traveling over the Internet could have a material and adverse impact on our financial condition and results of operations.
We could be materially adversely affected by increased regulation of the Internet and Internet commerce in any country where we operate, as well as access to or commerce conducted on the Internet. Further, governments may further regulate or restrict the sales, licensing, distribution, and export or import of certain technologies to certain countries. The adoption of additional regulation of the Internet and Internet commerce could decrease demand for our products, and, at the same time, increase the cost of selling our products, which could have a material and adverse effect on our financial condition and results of operations.
We are subject to stringent and changing laws, regulations, standards, contractual obligations, and other obligations related to privacy, data protection, and data security. The actual, alleged, or perceived failure by us or the partners we work with to comply with such obligations could adversely affect our business, results of operations, and financial conditions.
We are subject to numerous domestic and foreign laws and other obligations relating to privacy, data protection, and data security. The regulatory framework for data privacy and security issues worldwide is rapidly evolving, and as a result, legal requirements and enforcement practices are likely to continue to evolve. In many jurisdictions, enforcement activities and consequences for noncompliance are rising. In the United States, these activities include enforcement actions in response to rules and regulations promulgated under the authority of federal agencies, state attorneys general, states' legislation, and consumer protection agencies. In addition, privacy advocates and industry groups in the United States have regularly proposed,
and may propose in the future, self-regulatory security standards with which we may be required to comply. If we fail to follow these standards, we may incur significant fines or experience a significant increase in costs.
Internationally, the data protection landscape is also rapidly evolving, and we expect there will continue to be new and proposed laws, regulations, and industry standards concerning privacy, data protection, and data security. The General Data Protection Regulation ("GDPR") went into effect in the European Union ("EU") in May 2018 and has been adopted as law in the United Kingdom ("UK"). The GDPR requires companies to give detailed disclosures about how they collect, use, and share personal information; contractually commit to data protection measures in contracts with customers and vendors; maintain adequate data security measures; notify regulators and affected individuals of certain data breaches; meet extensive privacy governance and documentation requirements; and honor individuals’ data protection rights, including their rights to access, correct, and delete their personal information. The GDPR also requires controllers to conduct data protection impact assessments for certain types of processing and requires processors to assist controllers with such assessments, which may be complex and burdensome to conduct. Laws in EU member states and the UK also impose restrictions on direct marketing communications and the use of cookies and similar technologies online.
European data protection laws including the GDPR also generally prohibit the transfer of personal information from Europe to the United States and most other countries unless the parties to the transfer have implemented specific safeguards to protect the transferred personal information. there is uncertainty regarding how to ensure that transfers of personal information from Europe comply with European data protection laws. As such, any transfers of personal information from Europe by us or our partners may increase our exposure to the GDPR’s heightened sanctions for violations of its cross-border data transfer restrictions, and may reduce demand for our services from companies subject to European data protection laws. Loss of our ability to transfer personal information from Europe may also require us to increase our data processing capabilities in those jurisdictions at significant expense.
Complying with foreign and domestic data protection laws may cause us to incur additional operational costs or require us to change our business practices. Despite our efforts, we may fail to achieve full compliance either due to internal or external factors such as lack of vendor cooperation. Any actual, alleged, or perceived non-compliance could result in legal proceedings against us by governmental entities, customers, data subjects, or others.
We are or may become subject to the terms of our privacy and security policies, representations, certifications, standards, publications, and contractual obligations relating to privacy, data protection, and data security. Although we endeavor to comply with our obligations, we and the third parties on which we rely may at times fail to do so or may be perceived to have failed to do so. Such failures could subject us to regulatory enforcement action as well as costly legal claims by affected individuals or our customers.
We strive to comply with applicable privacy, data protection, and data security laws and other obligations, but we cannot fully determine the impact that current or future such laws and other obligations may have on our business or operations. Such laws or obligations may be inconsistent from one jurisdiction to another or subject to differing interpretations, and courts or regulators may deem our efforts to comply as insufficient. If we or the third parties we rely on to operate our business and deliver our services fail to comply, or are perceived as failing to comply, with our legal, contractual, or other obligations relating to privacy, data protection, or data security, or our policies and documentation relating to personal information, we could face governmental enforcement action; litigation with our customers, individuals or others, fines and civil or criminal penalties for us or company officials, obligations to cease offering our services or to substantially modify them in ways that make them less effective in certain jurisdictions, negative publicity and harm to our brand and reputation, and reduced overall demand for our services. Such developments could adversely affect our business, financial condition, and results of operations.
Foreign currency exchange rates may adversely affect our financial statements.
A material portion of our revenue is derived from international operations. Our consolidated financial results are reported in U.S. dollars. Most of the revenue and expenses of our foreign subsidiaries are denominated in local currencies. Given that cash is typically received over an extended period of time for many of our license agreements and given that a material and increasing portion of our revenue is generated outside of the United States, fluctuations in foreign exchange rates (including the Euro) against the U.S. dollar could result in substantial changes in reported revenues and operating results due to the foreign exchange impact upon translation of these transactions into U.S. dollars.
In the normal course of business, we employ various hedging strategies to partially mitigate these risks, including the use of derivative instruments. These strategies may not be effective in fully protecting us against the effects of fluctuations from movements in foreign exchange rates, including the increased volatility in foreign exchange rates during the COVID-19
pandemic and future global pandemics and other events. Fluctuations of the foreign exchange rates could materially adversely affect our business, financial condition, operating results, and cash flow.
Additionally, sales and purchases in currencies other than the U.S. dollar expose us to fluctuations in foreign currencies relative to the U.S. dollar and may adversely affect our financial statements. Increased strength of the U.S. dollar increases the effective price of our products sold in U.S. dollars into other countries, which may require us to lower our prices or adversely affect sales to the extent we do not increase local currency prices. Decreased strength of the U.S. dollar could adversely affect the cost of materials, products, and services we purchase overseas. Sales and expenses of our non-U.S. businesses are also translated into U.S. dollars for reporting purposes and the strengthening or weakening of the U.S. dollar could result in unfavorable translation effects. In addition, we may invoice customers in a currency other than the functional currency of our business, and movements in the invoiced currency relative to the functional currency could also result in unfavorable translation effects. We also face exchange rate risk from our investments in subsidiaries owned and operated in foreign countries.
If we violate the U.S. Foreign Corrupt Practices Act or applicable anti-bribery laws in other countries, or if we fail to comply with U.S. export controls and government contracting laws, our business could be harmed.
We earn a material portion of our total revenues from international sales. As a result, we must comply with complex foreign and U.S. laws and regulations, such as the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and other local laws prohibiting corrupt payments to government officials and others, as well as anti-competition regulations.
The U.S. Foreign Corrupt Practices Act (FCPA), which continues to see increased enforcement in recent years, generally prohibits U.S. companies and their intermediaries from making corrupt payments to foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment and requires companies to maintain appropriate record-keeping and internal accounting practices to accurately reflect the transactions of the company. Under the FCPA, U.S. companies may be held liable for actions taken by agents or local partners or representatives. In addition, regulators may seek to hold us liable for successor liability FCPA violations committed by companies which we acquire. We are also subject to the U.K. Bribery Act and may be subject to certain anti-corruption laws of other countries in which we do business.
In addition to anti-bribery and anti-corruption laws, we are also subject to the export and re-export control laws of the U.S., including the U.S. Export Administration Regulations (EAR) and the office of Foreign Asset Control (OFAC), as well as to U.S. government contracting laws, rules and regulations, and may be subject to government contracting laws of other countries in which we do business. If we or our distributors, resellers, agents, or other intermediaries fail to comply with the FCPA, the EAR, OFAC or U.S. government contracting laws, or the anti-corruption, export or governmental contracting laws of other countries, governmental authorities in the U.S. or other countries could seek to impose civil and/or criminal penalties, which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.
Violations of these laws and regulations could result in fines and penalties, criminal sanctions, restrictions on our business conduct and on our ability to offer our products and services in one or more countries. Such violations could also adversely affect our reputation with existing and prospective customers, which could negatively impact our operating results and growth prospects.
The current economic and geopolitical environment may impact some specific industries into which we sell and may lead our customers to delay or forgo technology investments and could have other impacts, any of which could materially adversely affect our business, financial condition, operating results and cash flows.
Many of our customers are concentrated in certain industries, including financial services, public sector, healthcare, and the service provider market. Certain industries may be more acutely affected by economic, geopolitical, and other factors, including public heath crises (including global pandemics such as the COVID-19 pandemic), and changes in U.S. trade policy with China and other countries, than other sectors. Our public sector customers are affected by federal, state, and local budget decisions. To the extent that one or more of the sectors in which our customer base operates is adversely impacted, whether as a result of general conditions affecting all sectors or as a result of conditions affecting only those particular sectors, our business, financial condition and results of operations could be materially and adversely impacted. If companies in our target markets reduce capital expenditures, we may experience a reduction in sales, longer sales cycles, slower adoption of new technologies as well as downward pressure on the price of our products. There can be no assurance that any decrease in sales resulting from the COVID-19 pandemic will be offset by increased sales in subsequent periods. Although the magnitude of the impact of the COVID-19 pandemic on our business and operations remains uncertain, the continued spread of COVID-19 or the occurrence of other epidemics and the imposition of related public health measures and travel and business restrictions could adversely impact our business, financial condition, operating results and cash flows.
International economic, political, legal, compliance and business factors could negatively affect our financial statements and growth.
We expect to continue to develop our sales and presence outside the U.S. Our international business (and particularly our business in high-growth markets) is subject to risks that are customarily encountered in non-U.S. operations, any of which could negatively affect our business, financial condition, and results of operations.
General Risk Factors
Our actual operating results may differ significantly from our guidance.
We generally release guidance regarding our future performance on our quarterly earnings conference calls, quarterly earnings releases, and otherwise. Such guidance, which includes forward-looking statements, reflects our management’s estimates as of the date of release and is based on projections prepared by our management. We may also decide not to release, or to defer, issuing guidance, where such guidance might not be appropriate or when we do not have sufficient visibility or clarity to issue such guidance. In those situations, we expect to communicate our reasons for not releasing or deferring release of guidance.
Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. The principal reason that we release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. We are not responsible for any projections or reports published by any such analysts or investors.
Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock.
Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this "Risk Factors" section in this report could result in the actual operating results being different from our guidance, and the differences may be adverse and material.
Our effective tax rate may fluctuate, which could increase our income tax expense and reduce our net income.
Our effective tax rate or the taxes we owe could be adversely affected by several factors, many of which are outside of our control, including:
•changes in the relative proportions of revenues and income before taxes in the various jurisdictions in which we operate that have differing statutory tax rates;
•changing tax laws, regulations, and interpretations in multiple jurisdictions in which we operate as well as the requirements of certain tax rulings;
•changes in the research and development tax credit laws;
•earnings being lower than anticipated in jurisdictions where we have lower statutory rates and being higher than anticipated in jurisdictions where we have higher statutory rates;
•the valuation of generated and acquired deferred tax assets and the related valuation allowance on these assets;
•transfer pricing adjustments;
•the tax effects of purchase accounting for acquisitions and restructuring charges that may cause fluctuations between reporting periods; and
•tax assessments or any related tax interest or penalties that could significantly affect our income tax expense for the period in which the settlements take place.
We are subject to income taxes in the United States and in numerous foreign jurisdictions. From time to time, we may receive notices that a tax authority in a particular jurisdiction believes that we owe a greater amount of tax than we have reported to such authority.
While we regularly assess the likelihood of adverse outcomes from such examinations and the adequacy of our provision for income taxes, there can be no assurance that such provision is sufficient and that a determination by a tax authority will not have an adverse effect on our results of operations. An adverse change in our effective tax rate could have a material and
adverse effect on our financial condition and results of operations and the price of our common stock could decline if our financial results are materially affected by an adverse change in our effective tax rate.
We may be impacted by changes in taxation, trade, and other regulatory requirements.
We are subject to income tax in local, national, and international jurisdictions. In addition, our products are subject to import and excise duties and/or sales or value-added taxes (VAT) in many jurisdictions. We are also subject to the examination of our tax returns and other tax matters by the Internal Revenue Service and other tax authorities and governmental bodies. We regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of our provision for taxes. Additionally, changes in or the improper application of import and excise duties and or sales taxes or VAT may negatively impact our operating results. There can be no assurance as to the outcome of these examinations. Fluctuations in tax rates and duties, changes in tax legislation or regulation or adverse outcomes of these examinations could have a material adverse effect on our results of operations, financial condition, and cash flows.
There is increased uncertainty with respect to tax policy and trade relations between the U.S. and other countries. Major developments in tax policy or trade relations, such as the imposition of unilateral tariffs on imported products, could have a material adverse effect on our results of operations, financial condition, and cash flows.
Our estimates and judgments related to critical accounting policies could be inaccurate.
We consider accounting policies related to revenue recognition, marketable securities, valuation of goodwill, intangible assets and other acquisition and divestiture accounting items, and share-based compensation to be critical in fully understanding and evaluating our financial results. Management makes judgments and creates estimates when applying these policies. These estimates and judgments affect, among other things, the reported amounts of our assets, liabilities, revenue and expenses, the amounts of charges accrued by us, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances and at the time they are made. If our estimates or the assumptions underlying them are not correct, actual results may differ materially from our estimates and we may need to, among other things, accrue additional charges or impair assets that could adversely impact our business. As a result, our operating results and financial condition could be materially and adversely impacted in future periods.
Our disclosure controls and procedures and internal control over financial reporting may not be effective.
Our disclosure controls and procedures and internal control over financial reporting may not prevent all material errors and intentional misrepresentations. Any system of internal control can only provide reasonable assurance that all control objectives are met. Some of the potential risks involved could include, but are not limited to, management judgments, simple errors or mistakes, misinterpretation, and willful misconduct regarding controls. Under Section 404 of the Sarbanes-Oxley Act, we are required to evaluate and determine the effectiveness of our internal control over financial reporting. Compliance with this provision requires management's attention and expense. Management's assessment of our internal control over financial reporting may or may not identify weaknesses that need to be addressed in our internal control system. If we are unable to conclude that our internal control over financial reporting is effective, investors could lose confidence in our reported financial information which could have an adverse effect on the market price of our stock or impact our borrowing ability. In addition, changes in operating conditions and changes in compliance with policies and procedures currently in place may result in inadequate disclosure controls and procedures and internal control over financial reporting in the future.
Our stock price has been subject to fluctuations, and will likely continue to be subject to fluctuations, which may be volatile and due to factors beyond our control.
The market price of our common stock is subject to wide fluctuations in response to various factors, some of which are beyond our control. In addition to the factors discussed in this "Risk Factors" section and elsewhere in this report, factors that could cause fluctuations in the market price of our common stock include the following:
•ratings changes by any securities analysts who follow our company;
•announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures, or capital commitments;
•changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;
•changes in accounting standards, policies, guidelines, interpretations, or principles;
•actual or anticipated developments in our business or our competitors’ businesses or the competitive landscape generally;
•developments or disputes concerning our intellectual property or our products and platform capabilities, or third-party proprietary rights;
•cybersecurity attacks or incidents;
•announced or completed acquisitions of businesses or technologies by us or our competitors;
•changes in our board of directors or management;
•announced or completed equity or debt transactions involving our securities;
•sales of shares of our common stock by us, our officers, directors, or other stockholders; and
•other events or factors, including those resulting from public health crises (including global pandemics such as the COVID-19 pandemic), war, incidents of terrorism, or responses to these events.
In addition, the market for technology stocks and the stock markets in general have experienced extreme price and volume fluctuations. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business, and adversely affect our business, results of operations, financial condition, and cash flows. A decline in the value of our common stock, including as a result of one or more factors set forth above, may result in substantial losses for our stockholders.

ITEM 3. LEGAL PROCEEDINGS
Item 3. Legal Proceedings
From time to time, we are subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on our financial condition, results of operations or cash flows.
As previously disclosed, in March 2016, Packet Intelligence LLC (Packet Intelligence or Plaintiff) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff’s Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff’s allegations and asserting that Plaintiff’s patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury trial was held to address the parties’ claims and counterclaims regarding infringement of three patents by the G10 and GeoBlade products, invalidity of these patents, and damages. On October 13, 2017, the jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3,500,000 for pre-suit damages and $2,250,000 for post-suit damages. The jury indicated that the awarded damages amounts were intended to reflect a running royalty. In September 2018, the Court entered judgment and "enhanced" the jury verdict in the amount of $2.8 million as a result of a jury finding. The judgment also awards pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last date being June 2022. Following the entry of final judgment, on June 12, 2019, we filed our Notice of Appeal. On July 14, 2020, the Court of Appeals for the Federal Circuit issued a decision vacating the $3,500,000 pre-suit damages award, affirming the $2,250,000 post-suit damages award, and remanding to the district court to determine what, if any, enhancement should be awarded. On March 15, 2021, NetScout filed a petition for a writ of certiorari to the United States Supreme Court, which was subsequently denied, challenging, among other issues, the basis for enhanced damages and the patentability of the claimed technology. NetScout continues to avail itself of its legal options. NetScout has concluded that the risk of loss associated with the post-suit damages award is "probable" in accounting terms, regardless of the options NetScout may pursue, and that the risk of loss associated with pre-suit damages is now remote. Accounting rules require us to provide an estimate for the range of potential liability. NetScout currently estimates that the range of liability is the sum of post-suit damages, plus pre- and post-judgment interest amounts and royalties owed on post-trial sales of the accused G10 and GeoBlade products. Any potential enhancement is not reasonably estimable but is likely within the range of $0 to $2,800,000.

Overview
We are an industry leader with over 35 years of experience in providing service assurance and cybersecurity solutions that are used by customers worldwide to protect their digital business services against disruption. Service providers and enterprises, including local, state and federal government agencies, rely on our solutions to achieve the visibility necessary to optimize network performance, ensure the delivery of high-quality, mission-critical applications and services, gain timely insight into the end user experience and protect their networks from attack. With our offerings, customers can quickly, efficiently and effectively identify and resolve issues that result in downtime, interruptions to services, poor service quality or compromised data, thereby driving compelling returns on their investments in their networks and broader technology initiatives. Some of the more significant technology trends and catalysts for our business include the evolution of customers' digital transformation initiatives such as the migration to cloud environments, the rapidly evolving cybersecurity threat landscape, business intelligence and analytics advancements, and the 5G evolution in both the service provider and enterprise verticals.
Our operating results are influenced by a number of factors, including, but not limited to, the mix and quantity of products and services sold, pricing, costs of materials used in our products, growth in employee-related costs, including commissions, and the expansion of our operations. Factors that affect our ability to maximize our operating results include, but are not limited to, our ability to introduce and enhance existing products, the marketplace acceptance of those new or enhanced products, continued expansion into international markets, development of strategic partnerships, competition, successful acquisition integration efforts, and our ability to control cost and make improvements in a highly competitive industry.
COVID-19 Impact
In March 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. The pandemic and these containment and mitigation measures have led to adverse impacts on the U.S. and global economies. Due to the critical nature of our products and services, we are considered critical under State and Federal guidelines. While we have begun a phased reopening at some of our facilities, we remain focused on protecting the health and well-being of our employees and continue to maintain work from home policies for a vast majority of our employees where feasible.
We continue to closely monitor the impact of the COVID-19 pandemic on all aspects of our business, including how it has impacted and could continue to impact our customers, employees, supply chain, and distribution network. In fiscal year 2021, the COVID-19 pandemic and resulting challenging macro-economic environment caused elongated purchasing cycles that impacted our revenue. For fiscal year 2022, as people in the world begin to get immunized and return to "normal", we expect that technology and project spending will resume and will be focused on advancing our products, growing revenue, enhancing earnings per share, and generating solid free cash flow.
We believe our current cash reserves and access to capital through our revolving credit facility leave us well-positioned to manage our business as the crisis continues and as a recovery eventually occurs. We expect net cash provided by operating activities combined with cash, cash equivalents and marketable securities and borrowing availability under our revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months. We continue to take actions to control costs and increase productivity throughout our company but will invest in areas that advance our business for the future, as necessary. In addition to our cash equivalents, based on covenant levels at March 31, 2021, we have an incremental $336 million available to us under our $1.0 billion revolving credit facility.
On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the CARES Act) was enacted. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. We have elected to defer the employer-paid portion of social security taxes. As of March 31, 2021, we had deferred $8.9 million of
employer payroll taxes, of which 50% are required to be deposited by December 2021 and the remaining 50% by December 2022.
The extent of the impact of the COVID-19 pandemic on our operational and financial performance will depend on certain developments, including the duration of the pandemic, its impact on our customers and suppliers and the range of governmental and community reactions to the pandemic, which continue to evolve and cannot be fully predicted at this time. We will continue to proactively respond to the situation and may take further actions that alter our business operations as may be required by governmental authorities, or that we determine are in the best interests of our stakeholders.
Results Overview
Total revenue for the fiscal year ended March 31, 2021 as compared to total revenue for the fiscal year ended March 31, 2020 was primarily impacted by a decrease in revenue from our service assurance offerings in both the service provider and enterprise verticals, partially offset by an increase in revenue from our cybersecurity offerings, or more particularly, the service portion of our DDoS offerings.
Our gross profit percentage remained flat at 73% during the fiscal year ended March 31, 2021 as compared with the fiscal year ended March 31, 2020.
Net income for the fiscal year ended March 31, 2021 was $19.4 million, as compared with a net loss for the fiscal year ended March 31, 2020 of $2.8 million, an increase of $22.2 million. A decrease in revenue of $60.5 million was more than offset by a decrease in expenses as the increase in net income was primarily due to a $23.5 million decrease in travel expenses primarily attributable to COVID-19 related restrictions, a $16.2 million decrease in direct material costs, a $9.4 million decrease in amortization of intangible assets, a $6.9 million decrease in expenses related to trade shows and other sales and marketing related events attributable to continued cost control and COVID-19 related restrictions, a $6.7 million decrease in legal fees and penalties, a $5.2 million decrease in commissions expense, a $5.0 million decrease in inventory-related charges, a $2.6 million decrease in restructuring charges, a $2.5 million decrease in advertising and other marketing related expenses, and a $2.0 million decrease in rent expense.
At March 31, 2021, we had cash, cash equivalents, and marketable securities (current and non-current) of $476.5 million. This represents an increase of $87.4 million compared to the fiscal year ended March 31, 2020. This increase was primarily due to $213.9 million in cash provided by operations during the fiscal year ended March 31, 2021. This increase was offset by $100.0 million used to repay long-term debt, $13.3 million used for tax withholdings in connection with the vesting of restricted stock units, $12.0 million used for capital expenditures, $4.5 million used for purchases of intangible assets and $3.3 million used to repurchase shares of our common stock during the fiscal year ended March 31, 2021.
Use of Non-GAAP Financial Measures
We supplement the United States generally accepted accounting principles (GAAP) financial measures we report in quarterly and annual earnings announcements, investor presentations and other investor communications by reporting the following non-GAAP measures: non-GAAP total revenue, non-GAAP gross profit, non-GAAP income from operations, non-GAAP operating margin, non-GAAP earnings before interest and other expense, income taxes, depreciation and amortization (EBITDA) from operations, non-GAAP net income, and non-GAAP net income per share (diluted). Non-GAAP revenue eliminates the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation. Non-GAAP gross profit includes the aforementioned revenue adjustments and also removes expenses related to the amortization of acquired intangible assets, share-based compensation, and acquisition-related depreciation. Non-GAAP income from operations includes the aforementioned adjustments and also removes business development and integration expense, compensation for post-combination services, legal judgments expense, restructuring charges, intangible asset impairment charges, loss on divestiture and costs related to new accounting standard implementation and adds back transitional service agreement income. Non-GAAP EBITDA from operations includes the aforementioned items related to non-GAAP income from operations and also removes non-acquisition-related depreciation expense. Non-GAAP net income includes the foregoing adjustments related to non-GAAP income from operations, net of related income tax effects in addition to the provisional one-time impacts of the U.S. Tax Cuts and Jobs Act (TCJA) while removing transitional service agreement income and changes in contingent consideration. Non-GAAP diluted net income per share also excludes these expenses as well as the related impact of all these adjustments on the provision for income taxes.
These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (revenue, gross profit, operating profit, net income (loss) and diluted net income (loss) per share), and may have limitations in that they do not reflect all our results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the
corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from, or as a substitute for results prepared in accordance with GAAP.
Management believes these non-GAAP financial measures enhance the reader's overall understanding of our current financial performance and our prospects for the future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how we plan and measure our business. We believe that providing these non-GAAP measures affords investors a view of our operating results that may be more easily compared with our peer companies and also enables investors to consider our operating results on both a GAAP and non-GAAP basis during and following the integration period of our acquisitions. Presenting the GAAP measures on their own may not be indicative of our core operating results. Furthermore, management believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provide useful information to management and investors regarding present and future business trends relating to our financial condition and results of operations.
The following table reconciles revenue, gross profit, income (loss) from operations, net income (loss) and net income (loss) per share on a GAAP and non-GAAP basis for the fiscal years ended March 31, 2021, 2020 and 2019:

Critical Accounting Policies
We consider accounting policies related to revenue recognition, marketable securities, valuation of goodwill, intangible assets and other acquisition and divestiture accounting items, and share-based compensation to be critical in fully understanding and evaluating our financial results. We apply significant judgment and create estimates when applying these policies.
Revenue Recognition
We exercise judgment and use estimates in connection with determining the amounts of product and service revenues to be recognized in each accounting period.
We derive revenues primarily from the sale of network management tools and security solutions for service provider and enterprise customers, which include hardware, software, and service offerings. Our product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions.
We account for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by us as an arrangement with commercial substance identifying payment terms, each party’s rights and obligations regarding the products or services to be transferred and the amount we deem probable of collection. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for products and services.
Product revenue is typically recognized upon shipment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software; and collection of the related receivable is probable. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. Our service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. We generally provide software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. Reimbursements of out-of-pocket expenditures incurred in connection with
providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training.
Generally, our contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts.
Bundled arrangements are concurrent customer purchases of a combination of our product and service offerings that may be delivered at various points in time. We allocate the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. We use a range of amounts to estimate SSP when we sell each of the products and services separately based on the element’s historical pricing. We also consider our overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, we have established SSP for a majority of our service elements based on historical standalone sales. In certain instances, we have established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. Further, for certain service engagements, we consider quoted prices as part of multi-element arrangements of those engagements as a basis for establishing SSP. SSP has been established for product elements as the average or median selling price the element was recently sold for, whether sold alone or sold as part of a multiple element transaction. We review sales of the product elements on a quarterly basis and update, when appropriate, SSP for such elements to ensure that it reflects recent pricing experience. Our products are distributed through our direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, when control of the product transfers to the reseller or distributor. We record consideration given to a customer as a reduction of revenue to the extent we have recorded revenue from the customer. With limited exceptions, our return policy does not allow product returns for a refund. Returns have been insignificant to date. In addition, we have a history of successfully collecting receivables from our resellers and distributors.
Marketable Securities
We measure the fair value of our marketable securities at the end of each reporting period. Fair value is defined as the exchange price that would be received for an asset in the principal or most advantageous market for the asset in an orderly transaction between market participants on the measurement date. Marketable securities are recorded at fair value and have been classified as Level 1 or 2 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in accessible active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves.
Valuation of Goodwill, Intangible Assets and Other Acquisition and Divestiture Accounting Items
We amortize acquired definite-lived intangible assets over their estimated useful lives. Goodwill and other indefinite-lived intangible assets are not amortized but subject to annual impairment tests; more frequently if events or circumstances occur that would indicate a potential decline in their fair value. We perform the assessment annually during the fourth quarter and on an interim basis if potential impairment indicators arise.
Reporting units are determined based on the components of a company's operating segments that constitute a business for which financial information is available and for which operating results are regularly reviewed by segment management. We have one reporting unit.
To test impairment, we first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that the intangible asset is impaired. If based on our qualitative assessment it is more likely than not that the fair value of the intangible asset is less than its carrying amount, quantitative impairment testing is required. However, if we conclude otherwise, quantitative impairment testing is not required. During the fourth quarter of fiscal year 2021, we performed our annual impairment analysis for goodwill at January 31, 2021 using the qualitative Step 0 assessment as we concluded that it was more likely than not that the fair value of the reporting unit exceeded its carrying value.
Indefinite-lived intangible assets are tested for impairment at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the indefinite-lived intangible assets below its carrying value. To test impairment, we first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that the indefinite-lived intangible is impaired. If based on our qualitative assessment, we conclude that it is more likely than not that the fair value of the indefinite-lived asset is less than its carrying amount, quantitative impairment testing is required. However, if we conclude otherwise, quantitative impairment testing is not required. During the fourth quarter of fiscal year 2021, we completed our annual impairment test of the indefinite-lived intangible asset at January 31, 2021 using the qualitative Step 0 assessment as we concluded that it was more likely than not that the fair value of the indefinite-lived asset exceeded its carrying value.
We completed two acquisitions and one divestiture during the three-year period ended March 31, 2021. The acquisition method of accounting requires an estimate of the fair value of the assets and liabilities acquired as part of these transactions. In order to estimate the fair value of acquired intangible assets, we use either an income, market or cost method approach.
Our Level 3 liabilities at March 31, 2020 consisted of contingent purchase consideration related to the two acquisitions that occurred during fiscal year 2020. The contingent purchase consideration related to the two acquisitions represent amounts deposited into escrow accounts, which were established to cover damages NetScout may have suffered related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the sellers as described in the acquisition agreements. The contingent purchase consideration of $0.7 million and $1.0 million related to the Gigavation Incorporated (Gigavation) and Eastwind Networks, Inc. (Eastwind) acquisitions, respectively are included as accrued other in our consolidated balance sheet at March 31, 2020. The $0.7 million of purchase consideration related to the Gigavation acquisition was paid to the seller in February 2021. The contingent purchase consideration related to the Eastwind acquisition was paid to the seller in April 2020.
During fiscal year 2019, we recorded a contingent consideration related to the divestiture of our handheld network test (HNT) tools business in September 2018. The contingent consideration represented potential future earnout payments to us of up to $4.0 million over two years that were contingent on the HNT tools business achieving certain milestones. The fair value of the contingent consideration of $2.3 million was recognized on the divestiture date and was measured using unobservable (Level 3) inputs. We recorded an $0.8 million and a $1.6 million change in the fair value of the contingent consideration, which is included in other expense, net within our consolidated statement of operations for the years ended March 31, 2020 and 2019.
Share-Based Compensation
We recognize compensation expense for all share-based payments. Under the fair value recognition provisions, we recognize share-based compensation net of an estimated forfeiture rate and only recognize compensation cost for those shares expected to vest on a straight-line basis over the requisite service period of the award.
We are required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from our estimate, the share-based compensation expense could be significantly different from what we have recorded in the current period.
Based on historical experience, we assumed an annualized forfeiture rate of 0% for awards granted to our directors, an annualized forfeiture rate of approximately 2% for awards granted to our senior executives, and an annualized forfeiture rate of approximately 5% for all remaining employees. We will record additional expense if the actual forfeitures are lower than estimated and will record a recovery of prior expense if the actual forfeitures are higher than estimated.

Product. The 22%, or $26.9 million, decrease in cost of product revenue compared to the same period last year was primarily due to a $16.2 million decrease in direct material costs due to a decrease in product revenue, a $6.0 million decrease in the amortization of intangible assets, a $4.7 million decrease in inventory obsolescence charges, a $1.2 million decrease in employee-related expenses largely due to the timing of certain projects partially offset by an increase in variable incentive compensation, a $0.8 million decrease in overhead costs, a $0.6 million decrease in shipping costs, and a $0.6 million decrease in supplies. These decreases were partially offset by a $2.5 million increase in contractor fees. The product gross profit percentage increased by three percentage points to 75% during the fiscal year ended March 31, 2021 as compared to the same period in the prior year. The 11%, or $33.8 million, decrease in product gross profit, corresponds with the 14%, or $60.6 million, decrease in product revenue, partially offset by the 22%, or $26.9 million, decrease in cost of product revenue.
Service. The 6%, or $6.8 million, increase in cost of service revenue compared to the same period last year was primarily due to a $5.0 million increase in employee-related expenses due to an increase in variable incentive compensation and the timing of certain projects, and a $2.2 million increase in contractor fees. These increases were partially offset by a $2.0 million decrease in travel expense primarily attributable to COVID-19 related restrictions. The service gross profit percentage decreased by two percentage points to 72% during the fiscal year ended March 31, 2021 compared to the fiscal year ended March 31, 2020. The 2%, or $6.7 million, decrease in service gross profit corresponds with the 6%, or $6.8 million, increase in cost of services, partially offset by the $0.1 million increase in service revenue.
Gross profit. Our gross profit decreased 6%, or $40.4 million, compared to the fiscal year ended March 31, 2020. This decrease is attributable to the 7%, or $60.5 million, decrease in revenue partially offset by the $20.1 million, or 8%, decrease in cost of revenue. The gross margin percentage remained flat at 73% during the fiscal year ended March 31, 2021 compared to the same period in the prior year.

Research and development. Research and development expenses consist primarily of personnel expenses, fees for outside consultants, overhead and related expenses associated with the development of new products and the enhancement of existing products.
The 5%, or $9.1 million, decrease in research and development expenses compared to the same period last year was primarily due to a $2.6 million decrease in travel expense primarily attributable to COVID-19 related restrictions, a $2.0 million decrease in depreciation expense, a $1.2 million decrease in rent and other facilities related expenses, and a $0.9 million decrease in contractor fees.
Sales and marketing. Sales and marketing expenses consist primarily of personnel expenses and commissions, overhead and other expenses associated with selling activities and marketing programs such as trade shows, seminars, advertising, and new product launch activities.
The 12%, or $33.8 million, decrease in total sales and marketing expenses compared to the same period last year was primarily due to a $17.3 million decrease in travel expense primarily attributable to COVID-19 related restrictions, a $6.9 million decrease in expenses related to trade shows, user conferences and other events attributable to continued cost control and COVID-19 related restrictions, a $5.1 million decrease in commissions expense, a $2.3 million decrease in advertising and other marketing related expenses, and a $2.2 million decrease in employee-related expenses due to a reduction in headcount, partially offset by an increase in variable incentive compensation.
General and administrative. General and administrative expenses consist primarily of personnel expenses for executive, financial, legal, and human resource employees, overhead, and other corporate expenditures.
The 11%, or $11.0 million, decrease in general and administrative expenses compared to the same period last year was primarily due to a $6.7 million decrease in legal-related expenses and penalties, a $1.6 million decrease in travel expense primarily attributable to COVID-19 related restrictions, a $1.0 million decrease in rent and other facilities related expenses, an $0.8 million decrease in contractor fees, and a $0.5 million decrease in sales and use taxes.
Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, and definite-lived trademark and tradenames related to the Comms Transaction, ONPATH Technologies, Inc., Simena, Psytechnics, Ltd, Network General Corporation, Avvasi Incorporated and Efflux.
The 5%, or $3.4 million, decrease in amortization of acquired intangible assets was due to a reduction in the amortization of intangible assets related to the Comms Transaction.
Restructuring. During fiscal years 2020 and 2019, we restructured certain departments to better align functions, drive productivity and improve efficiency. During fiscal year 2019, we also implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of these restructuring programs, we recorded $0.1 million and $2.7 million of restructuring charges related to one-time termination benefits during the fiscal years ended March 31, 2021 and 2020, respectively.

The 6%, or $0.9 million, decrease in interest and other expense, net was primarily due to a $9.7 million decrease in interest expense due to debt repayments on the credit facility as well as a decrease in the average interest rate, and a $0.7 million decrease in other expense due to a change in the fair value of the contingent consideration related to the HNT business divestiture recorded during the fiscal year ended March 31, 2020. These decreases were offset by a $4.8 million increase in foreign exchange expense, a $3.9 million decrease in interest income received on investments, and a $1.0 million decrease in transitional services agreement income related to the HNT business divestiture.
Income Tax Expense
The annual effective tax rate for fiscal year 2021 was 13.2%, compared to an annual effective tax rate of 243.1% for fiscal year 2020. Generally, the effective tax rate differs from the statutory tax rate due to state income taxes and foreign withholding taxes, partially offset by the tax benefit associated Foreign Derived Intangible Income deduction, foreign tax credits, research and development tax credits and earnings in jurisdictions subject to tax rates lower than the U.S. statutory rate.
The effective tax rate for the twelve months ended March 31, 2021 is lower than the effective rate for the twelve months ended March 31, 2020, primarily due to an increase in foreign derived intangible income benefit, a reduction in foreign withholding taxes, and a significant increase in pre-tax income as compared to the prior year.

At March 31, 2021, we have also excluded long-term deferred revenue of $103.3 million as such amounts will be recognized as services are provided.
At March 31, 2021, the total accrual of our retirement obligation for our chairman and CEO was $1.4 million. The payment stream for this retirement obligation is based upon the retirement date which is currently not determinable.
At March 31, 2021, the total amount of net unrecognized tax benefits for uncertain tax positions and the accrual for the related interest was $1.0 million. We are unable to make a reliable estimate when cash settlement, if any, will occur with a tax authority as the timing of examinations and ultimate resolution of those examinations is uncertain.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.
Commitment and Contingencies
We account for claims and contingencies in accordance with authoritative guidance that requires us to record an estimated loss from a claim or loss contingency when information available prior to issuance of our consolidated financial statements indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and the amount of the loss can be reasonably estimated. If we determine that it is reasonably possible, but not probable, that an asset has been impaired or a liability has been incurred, or if the amount of a probable loss cannot be reasonably estimated, then, in accordance with the authoritative guidance, we disclose the amount or range of estimated loss if the amount or range of estimated loss is material. Accounting for claims and contingencies requires us to use our judgment. We consult with legal counsel on those issues related to litigation and seek input from other experts and advisors with respect to matters in the ordinary course of business.
Acquisition related- Our Level 3 liabilities at March 31, 2020 consisted of contingent purchase consideration related to the two acquisitions that occurred during the fiscal year 2020. The contingent purchase consideration related to the two acquisitions represented amounts deposited into escrow accounts, which were established to cover damages we may have suffered related to any liabilities that we did not agree to assume or as a result of the breach of representations and warranties of the sellers as described in the acquisition agreements. The contingent purchase consideration of $0.7 million and $1.0 million related to the Gigavation and Eastwind acquisitions were included as accrued other in our consolidated balance sheet at March 31, 2020. The $0.7 million related to the Gigavation acquisition was paid to the seller in February 2021. The $1.0 million related to the Eastwind acquisition was paid to the seller in April 2020.
During fiscal year 2019, we paid $0.5 million and $5.0 million of contingent liabilities to the sellers of Efflux Systems, Inc. (Efflux) and Simena, LLC), respectively related to prior acquisitions.
Legal - From time to time, we are subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on our financial condition, results of operations or cash flows.
As previously disclosed, in March 2016, Packet Intelligence LLC (Packet Intelligence or Plaintiff) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff's Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff’s allegations and asserting that Plaintiff's patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury trial was held to address the parties’ claims and counterclaims regarding infringement of three patents by the G10 and GeoBlade products, invalidity of these patents, and damages. On October 13, 2017, the jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3,500,000 for pre-suit damages and $2,250,000 for post-suit damages. The jury indicated that the awarded damages amounts were intended to reflect a running royalty. In September 2018, the Court entered judgment and "enhanced" the jury verdict in the amount of $2.8 million as a result of a jury finding. The judgment also awards pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last date being June 2022. Following the entry of final judgment, on June 12, 2019, we filed our Notice of Appeal. On July 14, 2020, the Court of Appeals for the Federal Circuit issued a decision vacating the $3,500,000 pre-suit damages award, affirming the $2,250,000 post-suit damages award, and remanding to the district court to determine what, if any, enhancement should be awarded. On March 15, 2021, NetScout filed a petition for a writ of certiorari to the United States Supreme Court, which was subsequently denied, challenging, among other issues, the basis for enhanced damages and the patentability of the claimed technology. NetScout continues to avail itself of its legal options. NetScout has concluded that the risk of loss associated with the post-suit damages award is "probable" in accounting terms, regardless of the options NetScout may pursue, and that the risk of loss associated with pre-suit damages is now remote. Accounting rules require us to provide an estimate for the range of potential liability. NetScout currently estimates that the range of liability is the sum of post-suit
damages, plus pre- and post-judgment interest amounts and royalties owed on post-trial sales of the accused G10 and GeoBlade products. Any potential enhancement is not reasonably estimable but is likely within the range of $0 to $2,800,000.
Warranty and Indemnification- We warrant that our software and hardware products will substantially conform to the documentation accompanying such products on their original date of shipment. For software, which also includes firmware, the standard warranty commences upon shipment and generally expires 60 to 90 days thereafter. With regard to hardware, the standard warranty commences upon shipment and generally expires 60 days to 12 months thereafter. Additionally, this warranty is subject to various exclusions which include, but are not limited to, non-conformance resulting from modifications made to the software or hardware by a party other than NetScout; customers' failure to follow our installation, operation or maintenance instructions; and events outside of our reasonable control. We also warrant that all support services will be performed in a good and workmanlike manner. We believe that our product and support service warranties are consistent with commonly accepted industry standards. Warranty cost information is presented and no material warranty costs are accrued since service revenue associated with warranty is deferred at the time of sale and recognized ratably over the warranty period.
Contracts that we enter into in the ordinary course of business may contain standard indemnification provisions. Pursuant to these agreements, we may agree to defend third party claims brought against a partner or direct customer claiming infringement of such third party’s (i) U.S. patent and/or European Union (EU), or other selected countries' patents, (ii) Berne convention member country copyright, and/or (iii) U.S., EU, and/or other selected countries’ trademark or intellectual property rights. Moreover, this indemnity may require us to pay any damages awarded against the partner or direct customer in such type of lawsuit as well as reimburse the partner or direct customer for reasonable attorney's fees incurred by them from the lawsuit.
We may also agree from time to time to provide other forms of indemnification to partners or direct customers, such as indemnification that would obligate us to defend and pay any damages awarded to a third party against a partner or direct customer based on a lawsuit alleging that such third party has suffered personal injury or tangible property damage legally determined to have been caused by negligently designed or manufactured products.
We have agreed to indemnify our directors and officers and our subsidiaries' directors and officers if they are made a party or are threatened to be made a party to any proceeding (other than an action by or in the right of NetScout) by reason of the fact that the indemnified are agents of NetScout. The indemnity is for any and all expenses and liabilities of any type (including but not limited to, judgments, fines and amounts paid in settlement) reasonably incurred by the directors or officers in connection with the investigation, defense, settlement or appeal of such proceeding, provided they acted in good faith.

This $11.1 million decrease was due in part to a $14.0 million decrease from deferred income taxes, $10.5 million decrease from deferred revenue, a $10.3 million decrease from depreciation and amortization expense, a $4.6 million decrease from accounts receivable, a $3.5 million decrease from inventories, a $2.4 million decrease from prepaid expenses and other assets, a $0.9 million decrease from accrued compensation and other expenses, and an $0.8 million decrease from the change in fair value of contingent and contractual liabilities. These decreases were partially offset by a $22.1 million increase from net income, a $7.6 million increase from income taxes payable, a $2.8 million increase from operating lease liabilities, a $2.6 million increase from accounts payable, and a $1.0 million increase from share-based compensation. Accounts receivable days sales outstanding was 75 days at March 31, 2021 compared to 73 days at March 31, 2020 and 88 days at March 31, 2019.

During the fiscal years ended March 31, 2021, 2020 and 2019, we repurchased 154,271 shares, 7,116,159 shares and 543,251 shares of our common stock for $3.3 million, $175.0 million, and $14.5 million under our twenty-five million share repurchase program.
In connection with the delivery of common shares upon vesting of restricted stock units, we have withheld 506,917 shares for $13.3 million, 519,241 shares for $11.9 million and 451,683 shares for $11.9 million related to minimum statutory tax withholding requirements on these restricted stock units during the fiscal years ended March 31, 2021, 2020 and 2019, respectively. These withholding transactions do not fall under the repurchase program described above, and therefore do not reduce the amount that is available for repurchase under that program.
During the fiscal years ended March 31, 2021, 2020 and 2019, we repaid $100.0 million, $100.0 million and $50.0 million of borrowings under the Amended Credit Agreement, respectively.
Credit Facility
On January 16, 2018, we amended and expanded our existing credit agreement (Amended Credit Agreement) with a syndicate of lenders by and among: NetScout; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; J.P. Morgan Securities LLC, KeyBanc Capital Markets, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners; Fifth Third Bank, Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto.
The Amended Credit Agreement provides for a five-year $1.0 billion senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. We may elect to use the new credit facility for general corporate purposes or to finance the repurchase of up to twenty-five million shares of our common stock under our common stock repurchase plan. The commitments under the Amended Credit Agreement will expire on January 16, 2023, and any outstanding loans will be due on that date. During the fiscal year ended March 31, 2021, we repaid $100.0 million of borrowings under the Amended Credit Agreement. At March 31, 2021, $350 million was outstanding under the Amended Credit Agreement.
At our election, revolving loans under the Amended Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) JPMorgan's prime rate, (2) 0.50% in excess of the New York Federal Reserve Bank (NYFRB) rate, or (3) an adjusted one month LIBOR rate plus 1%; or (b) such adjusted LIBOR rate (for the interest period selected by us), in each case plus an applicable margin. For the period from the delivery of our financial statements for the quarter ended December 31, 2020, until we have delivered financial statements for the quarter ended March 31, 2021, the applicable margin will be 1.50% per annum for LIBOR loans and 0.50% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on our leverage ratio, ranging from 0.75% per annum for Base Rate loans and 1.75% per annum for LIBOR loans if our consolidated leverage ratio is less than or equal to 3.50 to 1.00, down to 0.00% per annum for Alternate Base Rate loans and 1.00% per annum for LIBOR loans if our consolidated leverage ratio is equal to or less than 1.50 to 1.00. As of March 31, 2021, the Company’s maximum allowed consolidated leverage ratio is 3.50 to 1.00.
On July 27, 2017, the U.K. Financial Conduct Authority (FCA) announced that it will no longer require banks to submit rates for the calculation of LIBOR after 2021. On March 5, 2021, the Intercontinental Exchange Benchmark Administration
(IBA), the FCA-regulated and authorized administrator of LIBOR, announced, and the FCA confirmed, that one week and two-month USD LIBOR settings will cease on December 31, 2021, and that the USD LIBOR panel will cease on June 30, 2023. IBA notes that any publication of the Overnight and 1, 3, 6 and 12 Months USD LIBOR settings based on panel bank submissions beyond December 31, 2021 will need to comply with applicable regulations, including as to representativeness. Based on current information from panel banks, IBA anticipates there being a representative panel for the continuation of these USD LIBOR settings through to June 30, 2023.
Our Amended Credit Agreement, which matures on January 16, 2023 prior to the June 30, 2023 cessation of USD LIBOR publications, provides for the Administrative Agent to determine if (i) adequate and reasonable means do not exist for ascertaining the LIBOR rate or (ii) the FCA or Government Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the LIBOR rate shall no longer be used for determining interest rates for loans and the Administrative Agent determines that (i) and (ii) above are unlikely to be temporary, then the Administrative Agent and NetScout would agree to transition to an Alternate Base Rate borrowing as described above or amend the Credit Agreement to establish an alternate rate of interest to LIBOR that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time.
Our consolidated leverage ratio is the ratio of our total funded debt compared to our consolidated adjusted EBITDA. Consolidated adjusted EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the definition of consolidated adjusted EBITDA in the Amended Credit Agreement.
Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of our financial statements for the quarter ended December 31, 2020 until we have delivered financial statements for the quarter ended March 31, 2021, the commitment fee will be 0.25% per annum, and thereafter the commitment fee will vary depending on the our consolidated leverage ratio, ranging from 0.30% per annum if our consolidated leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if our consolidated leverage ratio is equal to or less than 1.50 to 1.00.
Letter of credit participation fees are payable to each lender on the amount of such lender’s letter of credit exposure, during the period from the closing date of the Amended Credit Agreement to but excluding the date which is the later of (i) the date on which such lender’s commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for LIBOR loans. Additionally, we will pay a fronting fee to each issuing bank in amounts to be agreed to between us and the applicable issuing bank.
Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on LIBOR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the period is longer than three months. We may also prepay loans under the Amended Credit Agreement at any time, without penalty, subject to certain notice requirements.
Debt is recorded at the amount drawn on the revolving credit facility plus interest based on floating rates reflective of changes in the market which approximates fair value.
The loans and other obligations under the credit facility are (a) guaranteed by each of our wholly owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of us and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by us and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Amended Credit Agreement generally prohibits any other liens on the assets of NetScout and its restricted subsidiaries, subject to certain exceptions as described in the Amended Credit Agreement.
The Amended Credit Agreement contains certain covenants applicable to us and our restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. In addition, we are required to maintain certain consolidated leverage and interest coverage ratios. These covenants and limitations are more fully described in the Amended Credit Agreement. At March 31, 2021, we were in compliance with all of these covenants.
The Amended Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Amended Credit Agreement and related documents, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments may terminate
the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Amended Credit Agreement and the other loan documents.
In connection with NetScout's Amended Credit Agreement described above, we terminated our previous term loan dated as of July 14, 2015, by and among NetScout; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; J.P. Morgan Securities LLC, KeyBanc Capital Markets, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners; Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto.
We have capitalized debt issuance costs totaling $12.2 million at March 31, 2021, which are being amortized over the life of the revolving credit facility. The unamortized balance was $3.1 million as of March 31, 2021. The balance of $1.7 million was included as prepaid expenses and other current assets and a balance of $1.4 million was included as other assets in our consolidated balance sheet.
Expectations for Fiscal Year 2022
We are actively managing the business to maintain cash flow and believe that we currently have adequate liquidity. We believe that these factors will allow us to meet our currently anticipated funding requirements.
We expect net cash provided by operating activities combined with cash, cash equivalents, and marketable securities and borrowing availability under our revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirement over at least the next twelve months.
Additionally, a portion of our cash may be used to acquire or invest in complementary businesses or products, to obtain the right to use complementary technologies, to repay borrowings under our Amended Credit Agreement, or to repurchase shares of our common stock through our stock repurchase program. From time to time, in the ordinary course of business, we evaluate potential acquisitions of such businesses, products or technologies. If our existing sources of liquidity are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities. The sale of additional equity or debt securities could result in additional dilution to our stockholders.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk. We hold our cash, cash equivalents and investments for working capital purposes. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we maintain our portfolio of cash, cash equivalents and investments in a variety of securities, including money market funds and government debt securities. The risk associated with fluctuating interest rates is limited to our investment portfolio. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income. The effect of a hypothetical 10% increase or decrease in overall interest rates would not have had a material impact on our operating results or the total fair value of the portfolio.
We are exposed to market risks related to fluctuations in interest rates related to our credit facility. At March 31, 2021, we owed $350 million on this loan with an interest rate of 1.61%. A sensitivity analysis was performed on the outstanding portion of our debt obligation as of March 31, 2021. Should the current weighted average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest expense would be approximately $564 thousand as of March 31, 2021.
Credit Risk. Our cash equivalents and marketable securities consist primarily of money market instruments, U.S. Treasury bills, certificates of deposit, commercial paper, corporate bonds and municipal obligations.
At March 31, 2021 and periodically throughout the year, we have maintained cash balances in various operating accounts in excess of federally insured limits. We limit the amount of credit exposure with any one financial institution by evaluating the creditworthiness of the financial institutions with which we invest.
Foreign Currency Exchange Risk. As a result of our foreign operations, we face exposure to movements in foreign currency exchange rates, primarily the Euro, British Pound, Canadian Dollar and Indian Rupee. The current exposures arise primarily from expenses denominated in foreign currencies. We currently engage in foreign currency hedging activities in order to limit these exposures. We do not use derivative financial instruments for speculative trading purposes.
At March 31, 2021, we had foreign currency forward contracts designated as hedging instruments with notional amounts totaling $11.0 million and foreign currency forward contracts not designated as hedging instruments with a notional amount of $6.4 million. The valuation of outstanding foreign currency forward contracts (both designated and not designated as hedging instruments) at March 31, 2021 resulted in a liability balance of $191 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date and an asset balance of $57 thousand, reflecting favorable rates in comparison to current market rates. At March 31, 2020, we had foreign currency forward contracts designated as hedging instruments with notional amounts totaling $1.7 million. The valuation of outstanding foreign currency forward contracts designated as hedging instruments at March 31, 2020 resulted in a liability balance of $49 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date.

Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of March 31, 2021, NetScout, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Exchange Act. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of March 31, 2021 our disclosure controls and procedures were effective in ensuring that material information relating to NetScout, including its consolidated subsidiaries, required to be disclosed by NetScout in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
During the quarter ended March 31, 2021, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting was designed to provide reasonable assurance regarding reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. 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. Our management assessed the effectiveness of our internal control over financial reporting as of March 31, 2021. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework in 2013. Based on our assessment, we concluded that our internal control over financial reporting was effective as of March 31, 2021.
The effectiveness of our internal control over financial reporting as of March 31, 2021 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.
