PART I

Item 1. BUSINESS

Overview

American Superconductor Corporation (together with its subsidiaries, “AMSC®” or the “Company”) was founded on April 9, 1987. We are a leading system provider of megawatt-scale power resiliency solutions that orchestrate the rhythm and harmony of power on the grid, and that protect and expand the capability of the Navy’s fleet. Our system level products leverage the Company’s proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.

In the power grid market, we enable electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through our power electronics and superconductor-based systems as well as our transmission planning services. We protect and expand the capability of the U.S. Navy surface fleet with advanced superconductor-based systems which provide superior performance advantages to the traditional methods of mine field protection. In the wind power market, we enable manufacturers to field highly competitive wind turbines through our advanced power electronics and control system products, engineering, and support services. Our power grid and wind products and services provide exceptional reliability, security, efficiency, and affordability to our customers.

Our power system solutions help to improve energy efficiency, alleviate power capacity and other constraints, improve system resiliency, and increase the adoption of renewable energy generation. Demand for our solutions is driven by: the growing needs for modernized grids that improve power reliability, security, and quality, the U.S. Navy’s effort to upgrade in-board power systems to support fleet electrification, and the need for increased renewable sources of electricity, such as wind and solar energy. Concerns about these factors have led to increased spending by corporations and the military, as well as supportive government regulations and initiatives on local, state and national levels, including renewable portfolio standards, tax incentives, and international treaties.

Market opportunities

We provide solutions that address three key drivers of our business:

• the evolving electric grid;

• the electrification of the Naval fleet; and

• the global demand for renewable energy.

Our power system products address five market opportunities (areas):

• Transmission grid.  We provide complete systems that enable electric utilities and renewable energy project developers to connect and transmit power with exceptional efficiency, reliability, security and affordability. We provide planning services that allow us to identify power grid congestion, poor power quality, and other risks, which help us determine how our solutions can improve network performance. These services often lead to sales of our grid interconnection solutions and power quality systems for wind farms and solar power plants.  

• Distribution grid. We provide a direct-connect power quality system that is installed on the primary distribution network in communities, business parks, or wherever enhanced power quality is beneficial and is designed to increase the reliability and resiliency of the distribution grid to serve the needs of modern energy consumers. Our systems save utilities time and money by avoiding costly options to strengthen the distribution grid.

• Urban Grid Infrastructure. We design systems to increase the reliability, security and capacity of the urban grid infrastructure. Today, many urban substations are not networked and can only power a small section of a city. Our power dense technology based on proprietary smart materials allows for the inter-connection of substations, controlling the high fault currents that naturally result from such interconnections. If one substation is compromised, other substations help increase capacity and reliability. Our system allows instantaneous power outage recovery, potentially doubling to quadrupling a city’s reliability and resiliency while minimizing grid investment. We design systems that leverage existing grid assets while protecting cities against storms, outages, and cyber- and physical attacks.

• Marine protection systems.  We sell advanced degaussing systems to the U.S. Navy.  Our degaussing system creates a magnetic signature around a ship to mask the ship against sea mines and torpedoes. Our degaussing system is comprised of much smaller, lighter and higher performing HTS cable coils eliminating 50-80% of the system weight and saving 40-50% of the system power.

• Wind Power. Our solutions enable manufacturers to field wind turbines with exceptional power output, reliability, and affordability. We supply advanced power electronics and control systems, license our highly engineered wind turbine designs, and provide extensive customer support services to wind turbine manufacturers. Our design portfolio includes a broad range of drive trains and power ratings of 2 megawatts (“MW”) and higher. We provide a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the fiscal year beginning on April 1 of that same year. For example, fiscal 2019 refers to the fiscal year that began on April 1, 2019. Other fiscal years follow similarly.

Competitive strengths

We believe our competitive strengths position us well to execute on our growth plans in the markets we serve.

• Differentiated technologies. Our products leverage the Company’s proprietary smart materials and smart software and controls to provide enhanced resiliency and improved performance of megawatt-scale power flow. Conventional conductors of electricity, such as aluminum and copper wire, lose energy due to resistance. Using a compound of yttrium barium copper oxide (“YBCO”), we manufacture and provide high-temperature superconductor ("HTS") wire that can conduct many times more electricity than conventional conductors with minimal power loss. Our proprietary Amperium® superconductor wire was engineered to allow us to tailor the product via laminations to meet the electrical and mechanical performance requirements of widely varying end-use applications, including power cables and fault current limiters for the Grid market.  Our PowerModule™ power converters are based on proprietary software and hardware combinations and are used in a broad array of applications, including our D-VAR® grid interconnection and voltage control systems, as well as our wind turbine electrical control systems. Our unique proprietary cooler technology enables our ship protection systems ("SPS") to perform in harsh environmental conditions in a quiet and efficient manner.

• Turnkey systems. We have developed full system solutions that we sell directly to customers.  This business model leverages our applications expertise, drives value beyond the wire and enables us to recognize revenue and take ownership over the marketing and sales of the full systems.

• Scalable, low-cost manufacturing platform. Our manufacturing of proprietary wind turbine electrical control systems and power electronics products are primarily assembly operations with minimal fixed costs.  We can increase the production of these products at costs that we believe are low relative to our competitors. Our proprietary manufacturing technique for Amperium superconductor wire is modular in nature, which allows us to expand manufacturing capacity at a relatively low incremental cost.

• Robust patent position and engineering expertise. We have an extensive portfolio of awarded patents and patent applications worldwide and have rights through exclusive and non-exclusive licenses to additional patents and patent applications worldwide. We believe our technology and manufacturing knowledge base, customer and product expertise and patent portfolio provide a strong competitive position.

• Unique solutions for the markets we serve. We believe we provide wind turbine manufacturers with a unique and integrated approach of wind turbine design and engineering, customer support services and power electronics and control systems. We also believe we are the only company in the world that is able to provide transmission planning services, grid interconnection and voltage control systems, as well as superconductor-based distribution systems for power grid operators. This unique scope of supply provides us with greater insight into our customers’ evolving needs and greater cross-selling opportunities.

Strategy

Building on these competitive strengths, we plan to focus on driving revenue growth and enhancing our operating results through the objectives defined below.

• Provide solutions from power generation to delivery. From the generation source to the distribution system, we focus on providing best-in-class engineering, support services, technologies and solutions that make the world’s power supplies smarter, cleaner and more resilient.

• Focus on “megawatt-scale” power offerings. Our research, product development, and sales efforts focus on megawatt-scale offerings ranging from designs of power electronics for large wind turbine platforms to systems that stabilize power flows, integrate renewable power into the grid and carry power to and from transmission and distribution substations.

• Product innovation. We have a strong record of developing unique solutions for megawatt-scale power applications and will continue our focus on investing in innovation. Recently, our product development efforts have included our Resilient Electric Grid ("REG") system for the electricity grid, SPS for the U.S. Navy, and D-VAR Volt Var Optimization (“VVO”).

• Provide resiliency and protection capabilities. Our products provide resiliency and protection capabilities that support an evolving power grid and protect the navy fleet from rising global threats.

• Pursue Emerging Overseas Markets and Serve Key Markets Locally. We focus our sales efforts on overseas markets that are investing aggressively in renewable energy and power grid projects. As part of our strategy, we serve our key target markets with local sales and field service personnel, which enables us to understand market dynamics and more effectively anticipate customer needs while also reducing response time. We currently serve target markets such as Australia, China, India, Korea, South Africa, the United Kingdom, Jordan, Mexico and the United States.

Grid market overview

It is widely believed that the electricity grids around the world require modernization through widespread technology upgrades if they are to maintain reliability while solving rapidly evolving challenges such as more frequent severe weather, threats of physical- and cyber-attacks, expanded renewable generation (both large and small scale) and new types of customer loads such as electric vehicles.  In fact, a series of reports written by the Electric Power Research Institute ("EPRI") in 2016 emphasize the need for increased resiliency, flexibility and connectivity in electric grids.  According to the EPRI reports, the number of geophysical, meteorological, hydrological, and climatological events in the U.S. rose to an all-time high of 247 events in 2010 – up from approximately 200 in 2009 and less than 200 in all years combined from 1980 to 2010.  Available data further indicate that the existing U.S. electrical grid has been stressed by U.S. wind power generation increasing from 6 Gigawatts ("GW") in 2003 to 105 GW in 2019, and photovoltaics ("PV") power generation increasing from almost zero in 2003 to nearly 70 GW as of the end of 2019. 

Growth in both wind power and PV is expected to continue with the vast majority of such intermittent generation sources unsupported by energy storage, placing stress on the power grid.  Finally, the Edison Electric Institute estimates that the number of electric vehicles on the road in the U.S. is projected to reach 18.7 million in 2030, up from more than 1.0 million at the end of 2018.  These facts and the dependence on the safety, security and economy of the electricity grid have prompted broad recognition worldwide of the need to modernize and enhance the reliability and security of power grids.

Power grid operators worldwide face various challenges, including:

• Resiliency. As our electricity mix changes with the proliferation of renewables and distributed generation, so does the need to strengthen the electric grid. New technologies such as the addition of electric vehicles on U.S. roads and urbanization create new challenges for power grid operators.

• Stability. Power grid operators are confronting power quality and stability issues arising from intermittent renewable energy sources and from the capacity limitations of transmission and overhead distribution lines and underground cables.

• Reliability. Traditional transmission lines and cables often reach their reliable voltage stability limit well below their thermal threshold. Driving more power through a power grid when some lines and cables are operating above their voltage stability limit during times of peak demand can cause either unacceptably low voltage in the power grid (a brownout) or risk of a sudden, uncontrollable voltage collapse (a blackout).

• Capacity. The traditional way to enable increases in power grid capacity without losing voltage stability is to install more overhead power lines and underground cables. However, permitting new transmission and distribution lines can take 10 years or more due to various public policy issues, such as environmental, aesthetic, and health concerns. In urban and metropolitan areas, installing additional conventional underground copper cables is similarly challenging, since many existing underground corridors carrying power distribution cables are already filled to their physical capacity and cannot accommodate any additional conventional cables. In addition, adding new conduits requires excavation to expand existing corridors or create new corridors, which are costly and disruptive undertakings.

• Efficiency. Most overhead lines and underground cables use traditional conductors such as copper and aluminum, which lose power due to electrical resistance. At transmission voltage, electrical losses average about 7% in the United States and other developed nations, but can exceed 20% in some locations due to the distance of the line, quality of the conductor, and the power grid’s architecture and characteristics, among other factors.

• Security. Catastrophic equipment failures caused by aging equipment, physical and cyber events, and weather-related disasters can leave entire sections of an urban environment without power for hours or days.  It can be difficult to recover from extended power outages in urban load centers, worsening situations where the personal safety of residents and the economic health of businesses are threatened.

Our solutions for the power quality and grid infrastructure market

We address these challenges in the grid market by providing services and solutions designed to increase the power grid’s capacity, resiliency, reliability, security and efficiency.  Our solutions orchestrate the rhythm of power on the grid.  Our solutions include:

• D-VAR® Systems. Our D-VAR system is a system that consists of power electronics and other static components used for controlling power flow and voltage in the AC transmission system.  Our D-VAR system aims to increase controllability and power transferability of a network, which allows more effective utilization of existing assets, and reduces the need for new transmission lines and facilities to increase electricity availability. The power that flows through AC networks comprises both real power, measured in watts, and reactive power, measured in Volt Amp Reactive (“VARs”). In simple terms, reactive power is required to support voltage in the power network. D-VAR systems can provide the reactive power needed to stabilize voltage on the grid.  These systems also can be used to connect wind farms and solar power plants to the power grid seamlessly as well as to protect certain industrial facilities against voltage swells and sags.  Our D-VAR sales process begins with our group of experienced transmission planners working with power grid operators, renewable energy developers, and industrial system operators to identify power grid constraints and determine how our solutions might improve network performance.  These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, and power quality systems for utilities and heavy industrial operations.  

• D-VAR VVO®. Our D-VAR VVO serves the distribution power grid market. VVO is designed to be a direct-connect 15 kilovolt class power quality system for a utility's distribution network to optimally control voltage as distribution networks are increasingly impacted by distributed generation, such as roof top and community solar. We believe VVO has the potential to save utilities time and money by avoiding costly options to increase the reliability and resiliency of the distribution grid and to allow utilities to build a “plug 'n play” network to serve the demands of modern energy consumers. Our VVO target markets are electric distribution grids incorporating distributed generation, including where utility grid modernization attributes such as the following are applicable: mandated efficiency upgrades, mass adoption of rooftop solar, community solar, utility-owned micro-grids, variable load conditions on the distribution grid and voltage regulations alternatives.

• REG Systems. Our REG system has two primary applications that increase the reliability and the capacity of the urban infrastructure.  For applications focused on reliability improvement, the REG system is used in a “ring” or “loop” configuration to interconnect nearby urban substations.  This enables urban utilities to share transmission connections and excess station capacity, while controlling the high fault currents that naturally result from such interconnections, providing protection against the adverse effects that follow the loss of critical substation facilities in urban areas. We believe a utility installing our REG system could double or quadruple its reliability (e.g. N-1 to N-2, or greater) by networking substations, which is a solution that utilities would generally not consider when using conventional technology due to the disruptive nature and economic disadvantages of conventional technology in urban settings. For applications focused on capacity improvement, the REG system can be used in a “branch” configuration. In this application, the REG system connects an existing large urban substation with a new, much smaller, and more simplified substation within the city at a lower cost. The smaller urban substation does not need large power transformers and takes up much less space, thereby significantly reducing real estate, construction, and other related costs in the urban area. The key component to the REG system is a breakthrough cable system that combines very high-power handling capacity with fault current limiting characteristics - features that are attributable to our proprietary Amperium HTS wire.

Marine market overview

Defense spending has increased over the past two years as the U.S. military moves to rebuild and retool for competition against other great powers. In spring 2018, the Department of Defense submitted the Navy’s 2019 shipbuilding plan to Congress, covering government fiscal years 2019 to 2048, which if fully carried out, will represent the largest naval buildup since the Reagan Administration in the 1980s. 

In September 2019, the Navy’s fleet numbered 290 battle force ships—aircraft carriers, submarines, surface combatants, amphibious ships, combat logistics ships, and some support ships. The Navy’s 2020 shipbuilding plan reflects its 2016 force structure assessment and sets a goal of building and maintaining a fleet of 355 battle force ships.

Since WWII, the Navy fleet has protected its warfare vessels with copper-based degaussing systems. Our HTS-based degaussing system provides world class mine protection while reducing the weight of the degaussing system by as much as 80%, and reducing energy consumption by more than half that of legacy degaussing systems.

We believe that our HTS systems are an enabling technology for the Navy in its mission to create an all-electric ship (Super Ship). Our HTS-based SPS degaussing system has been designed into the San Antonio-class amphibious warfare ship platform, starting with LPD 28.  AMSC and the U.S. Navy have collaborated on AMSC’s advanced HTS-based ship protection systems. The core components of the ship protection system are common and transferable to other applications being targeted for ship implementation.

Navy fleets worldwide face various challenges, including:

• Power Capacity. Today’s Navy continues to see increased demand for more power applied from both on and off the ship (shore power). This need is driven by many factors, including the continued development of high-power density advanced weapons systems and sensors. Many power dense applications that naval engineers are working on today are already relying on the independent development of improved power distribution systems for its implementation. Free Electron Lasers, High Power Radar, Laser Self Defense Systems, Electro Magnetic Rail Guns and Active Denial (Directed Energy) systems are just a few of the Navy applications that we believe will demand higher capacity and more efficient energy transfer before deployment to a platform in the fleet can be realized.

• Space and Weight Limitations. Advances in sensors and weapons for modern ship applications are expected to drive the need for new power solutions to be light and compact, for weapons’ power draw to be more efficiently cooled and for easing installation on new ships and enabling upgrades on existing ones.

• Efficiency. Increased power demands for routine (peace time) operations are straining the conventional copper based power cable systems that are currently used. The copper cables are very heavy, cumbersome, and hard to handle. The weight of the cables requires a coordinated effort between a crew on the pier and a crew on the ship. In many instances, handling these cables requires the use of a crane or a boom truck to extend them from the pier-side power substations up to the ship’s connection point. More efficient, compact, lighter weight power transfer and distribution systems are expected to be required for tomorrow’s Navy to satisfy its future mission requirements.

Our solutions for the marine market

Each Navy ship can be thought of as having its own power grid.  We provide advanced ship protection systems, power management, and power generation systems that are designed to help fleets increase system efficiencies, enhance warfare capabilities, and boost reliability, performance and security. Our systems support the Navy’s mission to “electrify the fleet”.  Our systems allow for the ship to generate a large amount of electrical power and distribute the  power through an in-board power system to a propulsion motor by way of a much smaller, lighter, and higher performing HTS cable system, enabling a more advanced, reliable, and secure solution with a smaller footprint. Our solutions include:

• Ship Protection Systems.  The primary focus of our SPS has been degaussing systems. These systems reduce a naval ship’s magnetic signature, making it much more difficult for a mine to detect and damage a ship.  Traditionally made of heavy copper wire, degaussing is required on all U.S. Navy combat ships.  Our HTS advanced degaussing system is lightweight, compact, and often outperforms its conventional counterpart.  This HTS system is estimated to enable up to an 80% reduction in total degaussing system weight, offering significant potential for fuel savings or options to add different payloads. The core components of a degaussing system are transferable to other applications being targeted for ship implementation. Our SPS has been designed into the San Antonio class of amphibious assault vessels.  We are also seeking opportunities to propagate SPS throughout the surface fleet, creating a relatively long-term revenue stream. 

• In Board Power Delivery Systems.  We are working on expanding HTS technology into the fleet through a variety of applications, including in board power flow and management. The Navy continues to see increased demand for more power. This need is driven by many factors, including the continued development of high power density advanced weapons systems and sensors. Many power dense applications that naval engineers are working on today are already relying on improved power distribution systems for their implementation and deployment. Free Electron Lasers, High Power Radar, Laser Self Defense Systems, Electro Magnetic Rail Guns and Active Denial (Directed Energy) systems are just a few of the Navy applications that will demand higher capacity and more efficient energy transfer before deployment to a platform in the fleet can be realized. Continued space and weight limitations for these ship applications are expected to drive the need for new power solutions to be light and compact, easing installation on new ships and enabling upgrades on existing ones. Our HTS power cables enable high density energy transfer at unsurpassed efficiency levels in a compact, lightweight package.

• Power Generation Systems.   We are also working on expanding HTS technology into the fleet through a variety of applications including power generation and electric propulsion. The same HTS technology used in SPS and in board power delivery systems when applied to rotating machines results in high power density motors and generators. This enables dramatically more power to be produced in the same machinery space used for conventional systems, which in turn affords the Navy additional power for high energy density weapons without significant structural changes to the ship.

• Propulsion systems. Our development work in power generation systems for the Navy extends to HTS-based electric power propulsion. In board power delivery systems and power generation systems, when applied to high power density motors, enable the transition to electric propulsion. This is expected to make new ships more fuel-efficient. Our technology and systems allow the Navy to free up space for additional war-fighting capability.

Wind market overview

The global energy mix is transitioning towards an increasing amount of renewable energy, including wind power. Wind power is unlimited in supply and its generation is a zero-emission process. Wind power has become a major pillar of power supply throughout the world. Wind power is expected to play a key role in the achievement of the objectives of the Paris Climate Change agreement and the Sustainable Development Goals.

According to GlobalData, a research firm, approximately 57 GW of wind generation capacity were added worldwide in calendar 2019, as compared to 52 GW in calendar 2018.  GlobalData anticipates that more than 64 GW of additional capacity will be added in 2020.

According to GlobalData, annual wind installations in India for calendar 2019 were 2.7 GW and for calendar 2020 are estimated to be 4.1 GW.

Several factors are expected to drive the future growth in the wind power market, including substantial government incentives and mandates that have been established globally, technological improvements, turbine cost reductions, the development of the offshore wind market, and increasing cost competitiveness with existing power generation technologies. Technological advances, declining turbine production cost and fluctuating prices for some fossil fuels continue to increase the competitiveness of wind versus traditional power generation technologies.

Our solutions for the wind market

We address the challenges of the wind power market by designing and engineering wind turbines, providing extensive support services to wind turbine manufacturers, and manufacturing and selling critical components for wind turbines.

• Electrical Control Systems. We provide full electrical control systems (“ECS”) to manufacturers of wind turbines designed by us. Our ECS regulate voltage, control power flows and maximize wind turbine efficiency, among other functions. To date, we have shipped enough core electrical components and complete ECS to power over 16,000 Megawatts (“MW”) of wind power. We believe our ECS represent approximately 5-10% of a wind turbine’s bill of materials.

• Wind Turbine Designs. We design and develop entire state-of-the-art onshore and offshore wind turbines with power ratings of 2 MWs and higher for manufacturers who are in the business of producing wind turbines or who plan to enter the business of manufacturing wind turbines. These customers typically pay us licensing fees, and in some cases royalties, for wind turbine designs, and purchase from us the ECS needed to operate the wind turbines.

• Customer Support Services. We provide extensive customer support services to wind turbine manufacturers. These services range from providing designs for customers’ wind turbine manufacturing plants to establishing and localizing their supply chains and training their employees on proper wind turbine installation and maintenance. We believe these services enable customers to accelerate their entry into the wind turbine manufacturing market and lower the cost of their wind turbine platforms.

Our approach to the wind energy markets allows our customers to use our world-class turbine engineering capabilities while minimizing their research and development costs. These services and our advanced ECS provide our customers with the ability to produce standardized or next-generation wind turbines at scale for their local market or the global market quickly and cost-effectively. Our team of highly experienced engineers works with clients to customize turbine designs specifically tailored to local markets while providing ongoing access to field services support and future technological advances.

• Pewaukee, Wisconsin — Grid segment research and development

• Richland, Washington — Grid segment research and development

• Klagenfurt, Austria —Wind segment project engineering, customer support and research and development

• Timisoara, Romania —Wind segment manufacturing

Our global footprint also includes sales and/or field service offices in Australia, China, India, South Korea, the United Kingdom and McLean, VA.

The principal raw materials used in the manufacture of the Company’s products are nickel, silver, yttruim, copper, brass, and stainless steel. Major components are insulated gate bi-polar transistors, heatsinks, inductors, enclosures, transformers, and printed circuit boards. Most of these raw materials are available from multiple sources in the United States and world markets. Generally, the Company believes that adequate alternative sources are available for the majority of its key raw material and purchased component needs, however, the Company is dependent on a single or limited number of suppliers for certain materials and components.

Sales and Marketing

Our strategy is to serve customers locally in our core target markets through a direct sales force operating out of sales offices worldwide. In addition, we utilize manufacturers’ sales representatives in the United States to market our products to utilities in North America.  The sales force also leverages business development staff for our various offerings as well as our team of wind turbine engineers and power grid transmission planners, all of whom help to ensure that we have an in-depth understanding of customer needs and provide cost-effective solutions for those needs.

Segments

We segment our operations into two market-facing business units: Grid and Wind. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of power generation project developers, the Navy's ship protection systems, electric utilities and wind turbine manufacturers.

Competition

We face competition in various aspects of our technology and product development. We believe that competitive performance in the marketplace depends upon several factors, including technical innovation, range of products and services, product quality and reliability, customer service and technical support.

We face competition from other companies offering FACTS systems similar to our D-VAR products. These include adaptive VAR compensators, Dynamic voltage restorers (“DVRs”), and STATCOMs produced by ABB, Siemens, RXHK, NR Electric Co,. and Ingeteam, and battery-based uninterruptable power supply (“UPS”) systems offered by various companies around the world.

With our HTS-based REG product, we are offering a new approach that provides alternatives to utilities for power system design. Therefore, we believe that we compete with traditional approaches such as new full-sized substations, overhead and underground transmission, and urban power transformers.

We believe we are currently the only company that can offer HTS-based SPS products that have been fully qualified for use aboard U.S. Navy surface combatants.  Therefore, the primary competition for our SPS products is currently coming from defense contractors that provide the copper-based systems that our lighter, more efficient HTS versions have been developed to replace.  Companies such as L3, Excelis, Raytheon, and Textron have the bulk of the copper-based business today.  

Our power module conversion equipment and our electrical control systems are designed and integrated into our wind turbine designs in a way to achieve maximum performance of the turbine. Typically, we are the exclusive provider of the power module conversion equipment and electrical control systems for our wind turbine designs. As a result, our power conversion equipment and electrical control systems see limited competition. Other companies that serve the wind turbine components industry include ABB, and Semikron. We also face indirect competition in the wind energy market from global manufacturers of wind turbines, such as Siemens Gamesa, General Electric, and Suzlon. We face competition for the supply of wind turbine engineering design services from design engineering firms such as Aerodyn.

Patents, licenses and trade secrets

Patent Background

An important part of our business strategy is to develop a strong worldwide patent position in all of our technology areas. Our intellectual property (“IP”) portfolio includes both patents we own and patents we license from others. We devote substantial resources to building a strong patent position. Together with the international counterparts of our patents and patent applications, we own an extensive portfolio of patents and patent applications worldwide and have rights through exclusive and non-exclusive licenses. We believe that our current patent position, together with our ability to obtain licenses from other parties to the extent necessary, will provide us with sufficient proprietary rights to develop and sell our products. However, for the reasons described below, we cannot assure you that this will be the case.

Despite the strength of our patent position, a number of U.S. and foreign patents and patent applications of third parties relate to our current products, to products we are developing, or to technology we are now using in the development or production of our products. We may need to acquire licenses to those patents, contest the scope or validity of those patents, or design around patented processes or applications as necessary. If companies holding patents or patent applications that we need to license are competitors, we believe the strength of our patent portfolio will significantly improve our ability to enter into license or cross-license arrangements with these companies. We have already successfully negotiated cross-licenses with several competitors.

Failure to obtain all necessary patents, licenses and other IP rights upon reasonable terms could significantly reduce the scope of our business and have a material adverse effect on our results of operations. We do not now know the likelihood of successfully contesting the scope or validity of patents held by others. In any event, we could incur substantial costs in challenging the patents of other companies. Moreover, third parties could challenge some of our patents or patent applications, and we could incur substantial costs in defending the scope and validity of our own patents or patent applications whether or not a challenge is ultimately successful.

Grid Patents

We have received patents and filed a significant number of additional patent applications on power quality and reliability systems, including our D-VAR products. Our products are covered by patents and patents pending worldwide on both our systems and power converter products. The patents and applications focus on inventions that significantly improve product performance and reduce product costs, thereby providing a competitive advantage. One invention of note allows for a reduction in the number of power inverters required in the system by optimally running the inverters in overload mode, thereby significantly reducing overall system costs. Another important invention uses inverters to offset transients due to capacitor bank switching, which provides improved system performance.

HTS Patents

Since the discovery of high temperature superconductors in 1986, rapid technical advances have characterized the HTS industry, which in turn have resulted in a large number of patents, including overlapping patents, relating to superconductivity. As a result, the patent situation in the field of HTS technology and products is unusually complex. We have obtained licenses to patents and patent applications covering some HTS materials. We currently have non-exclusive rights to a fundamental U.S. patent (U.S. 8,060,169 B1) covering 2G and similar HTS wire and applications and may elect in the future to allow our rights under this license to lapse. However, we may have to obtain additional licenses to HTS materials and, upon expiration of U.S. 8,060,169 patent to the materials covered by such patent.

We are focusing on the production of our Amperium wire, and we intend to continue to maintain a leadership position in 2G HTS wire through a combination of patents, licenses and proprietary expertise. In addition to our owned patents and patent applications in 2G HTS wire, we have obtained licenses from (i) MIT for the MOD process we use to deposit the YBCO layer, and (ii) Alcatel-Lucent on the YBCO material.

We have extensive patents and patents pending covering applications of HTS wire, such as HTS fault current limiting technology including our fault current limiting cable, HTS rotating machines and ship protection systems. Since the superconductor rotating machine and the fault current limiting cable applications are relatively new, we are building a particularly strong patent position in these areas. At present, we believe we have the world’s broadest and most fundamental patent position in superconductor rotating machines technology. We have also filed a series of patents on our concept for our proprietary fault current limiting technology. However, there can be no assurance that that these patents will be sufficient to assure our freedom of action in these fields without further licensing from others. See Part I, Item 1A, “Risk Factors,” for more information regarding the status of the commercialization of our Amperium wire products.

Wind Patents

Under our Windtec Solutions™ brand, we design a variety of wind turbine systems and license these designs, including expertise and patent rights, to third parties for an upfront fee, plus in some cases, future royalties. Our wind turbine designs are covered by patents and patents pending worldwide on wind turbine technology. We have patent coverage on the unique design features of our blade pitch control system, which ensures optimal aerodynamic flow conditions on the turbine blades and improves system efficiency and performance. The pitch system includes a patented SafetyLOCK™ feature that causes the blades to rotate to a feathered position to prevent the rotor blades from spinning during a fault.

Trade Secrets

Some of the important technology used in our operations and products is not covered by any patent or patent application owned by or licensed to us. However, we take steps to maintain the confidentiality of this technology by requiring all employees and all consultants to sign confidentiality agreements and by limiting access to confidential information. We cannot provide any assurance that these measures will prevent the unauthorized disclosure or use of that information. In addition, we cannot provide any assurance that others, including our competitors, will not independently develop the same or comparable technology that is one of our trade secrets.

Employees

As of March 31, 2020, we employed 242 persons. None of our employees is represented by a labor union.

Item 1A. RISK FACTORS

Risks Related to Our Financial Performance

We have a history of operating losses, which may continue in the future. Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter.

We were not profitable in fiscal 2019 and have recorded net losses in two of the last three fiscal years.  While we did report net income of $26.8 million for the fiscal year ended March 31, 2019, it was largely as a result of the receipt of payments from Sinovel Wind Group Co. Ltd. pursuant to the terms of the Settlement Agreement described further herein. We may not be profitable in fiscal 2020 or future years.

There is currently substantial uncertainty in our business, which makes it difficult to evaluate our business and future prospects. In addition, our operating results historically have been difficult to predict and have at times fluctuated from quarter to quarter due to a variety of factors, many of which are outside of our control. As a result of all of these factors, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance.  In addition, we have in the past, and may continue to, provide public guidance on our expected operating and financial results for future periods. Such guidance is comprised of forward-looking statements subject to the risks and uncertainties described in this Annual Report on Form 10-K and in our other public filings and statements. Our actual results may not always be in line with or exceed the guidance we have provided.  If our revenue or operating results fall below the expectations of investors or any securities analysts that follow our company in any period or we do not meet our guidance, the trading price of our common stock would likely decline.

Our operating expenses do not always vary directly with revenue and may be difficult to adjust in the short term. As a result, if revenue for a particular quarter is below our expectations, we may not be able to proportionately reduce operating expenses for that quarter, and therefore such a revenue shortfall would have a disproportionate effect on our operating results for that quarter.

We have a history of negative operating cash flows, and we may require additional financing in the future, which may not be available to us.

As of March 31, 2020, we had approximately $66.1 million of cash, cash equivalents, marketable securities and restricted cash, and during the fiscal year ended March 31, 2020, we used $16.5 million in cash for our operating activities. We have historically experienced net losses, although we did report net income of $26.8 million for the fiscal year ended March 31, 2019. We plan to continue to closely monitor our expenses and, if required, will further reduce operating costs and capital spending to enhance liquidity.

Our liquidity is highly dependent on our ability to profitably grow our revenues, control our operating costs, and secure additional financing, if required.  We may require additional capital to conduct our business and adequately respond to future business challenges or opportunities, including, but not limited to, the need to develop new products or enhance existing products, maintain or expand research and development projects, collateralize performance bonds or letters of credit, and the need to build inventory or to invest other cash to support business growth.  In order to raise additional capital, we may offer shares of our common stock or other securities convertible into or exchangeable for our common stock. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of each of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders.

In the event that additional liquidity is required, there can be no assurance that such financing would be available or, if available, that such financing could be obtained upon terms acceptable to us, which would have a material adverse effect on our business, financial condition and prospects.

We may be required to issue performance bonds or provide letters of credit, which restricts our ability to access any cash used as collateral for the bonds or letters of credit.

While we have been required to provide performance bonds in the form of surety bonds or other forms of security and letters of credit in the past, the size of the bonds and letters of credit was not material. In recent years, we have entered into contracts that require us to post bonds and to deliver letters of credit of significant magnitude. For example, as part of the agreement with Commonwealth Edison Company (“ComEd”) to install the Resilient Electric Grid (“REG”) system in Chicago, we delivered an irrevocable letter of credit in the amount of $5.0 million to secure certain of our obligations under the Subcontract Agreement and deposited $5.0 million in an escrow account as collateral to secure such letter of credit. Similarly, in many other instances, we have been required to deposit cash in escrow accounts as collateral for these instruments, which is unavailable to us for general use for significant periods of time. Should we be unable to obtain performance bonds or letters of credit in the future, significant future potential revenue could become unavailable to us. Further, should our working capital situation deteriorate, we would not be able to access the restricted cash to meet working capital requirements.

Changes in exchange rates could adversely affect our results of operations.

Currency exchange rate fluctuations could have an adverse effect on our revenues and results of operations, and we could experience losses with respect to hedging activities. In fiscal 2019, 51% of our revenues were recognized from sales outside of the United States. In addition, approximately 21% of our revenues in fiscal 2019 were derived under sales contracts where prices were denominated in the Euro. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in a lesser number of orders, and therefore lower revenues, from such customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be adversely affected. In addition, most sales made by our foreign subsidiaries are denominated in the currency of the country in which these products are sold, and the currency they receive in payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations.  However, we cannot be certain that our efforts will be adequate to protect us against significant currency fluctuations or that such efforts will not expose us to additional exchange rate risks.

12

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired and may lead investors and other users to lose confidence in our financial data.

Maintaining effective internal control over financial reporting is necessary for us to produce reliable financial statements.

We note that a system of procedures and controls, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all systems of procedures and controls, no evaluation can provide absolute assurance that all control issues, including instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and breakdowns can occur because of simple errors or mistakes. Additionally, procedures and controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override. The design of any system of procedures and controls also is based, in part, upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, our systems of procedures and controls, as we further develop and enhance them, may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective system of procedures and controls, misstatements due to errors or fraud may occur and not be detected. Such misstatements could be material and require a restatement of our financial statements.

If we are unable to maintain effective internal controls, we may not have adequate, accurate or timely financial information, and we may be unable to meet our reporting obligations or comply with the requirements of the SEC or the Sarbanes-Oxley Act of 2002, which could result in the imposition of sanctions, including the inability of registered broker dealers to make a market in our common stock, or an investigation by regulatory authorities. Any such action or other negative results caused by our inability to meet our reporting requirements or to comply with legal and regulatory requirements or by our disclosure of an accounting, reporting or control issue could adversely affect the trading price of our securities and our business. Significant deficiencies or material weaknesses in our internal control over financial reporting could also reduce our ability to obtain financing or could increase the cost of any financing we obtain.

Risks Related to Our Operations

We may not realize all of the sales expected from our backlog of orders and contracts.

We cannot assure you that we will realize the revenue we expect to generate from our backlog in the periods we expect to realize such revenue, or at all.

In addition, the backlog of orders, if realized, may not result in profitable revenue. Backlog represents the value of contracts and purchase orders received for which delivery is expected in the next twelve months. Our customers have the right under some circumstances and with some penalties or consequences to terminate, reduce or defer firm orders that we have in backlog. In addition, our government contracts are subject to the risks described below. If our customers terminate, reduce or defer firm orders, we may be protected from certain costs and losses, but our sales will nevertheless be adversely affected, and we may not generate the revenue we expect.

Although we strive to maintain ongoing relationships with our customers, there is an ongoing risk that they may cancel orders or reschedule orders due to fluctuations in their business needs or purchasing budgets.

This has had, and may continue to have, an adverse effect on our ability to grow our revenues. In addition, current and future suppliers may be less likely to grant us credit, resulting in a negative impact on our working capital and cash flows.

Our contracts with the U.S. government are subject to audit, modification or termination by the U.S. government and include certain other provisions in favor of the government. The continued funding of such contracts remains subject to annual congressional appropriation, which, if not approved, could reduce our revenue and lower or eliminate our profit.

As a company that contracts with the U.S. government, we are subject to financial audits and other reviews by the U.S. government of our costs and performance, accounting, and general business practices relating to these contracts. Based on the results of these audits, the U.S. government may adjust our contract-related costs and fees. We cannot be certain that adjustments arising from government audits and reviews would not have a material adverse effect on our results of operations.

Our U.S. government contracts customarily contain other provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts, including provisions that allow the government to:

• obtain certain rights to the intellectual property that we develop under the contract;

• decline to award future contracts if actual or apparent organizational conflicts of interest are discovered, or to impose organizational conflict mitigation measures as a condition of eligibility for an award;

• suspend or debar us from doing business with the government or a specific government agency; and

• pursue criminal or civil remedies under the False Claims Act, False Statements Act and similar remedy provisions unique to government contracting.

All of our U.S. government contracts, as well as certain of our contracts with third parties that are dependent on U.S. government contracts, can be terminated by the U.S. government for its convenience, including our contract with the Department of Homeland Security (“DHS”) to deploy our REG system in ComEd’s electric grid in Chicago, Illinois (“Project REG”).  Termination-for-convenience provisions typically provide only for our recovery of costs incurred or committed, and for settlement of expenses and profit on work completed prior to termination. In addition to the right of the U.S. government to terminate its contracts with us, U.S. government contracts are conditioned upon the continuing approval by the U.S. Congress of the necessary spending to honor such contracts. Congress often appropriates funds for a program on a fiscal year basis even though contract performance may take more than one year. Consequently, at the beginning of many major governmental programs, contracts often may not be fully funded, and additional monies are then committed to the contract only if, as and when appropriations are made by the U.S. Congress for future fiscal years.  In addition, government shutdowns could prevent or delay such contracts from being funded.

13

We cannot be certain that our U.S. government contracts, including our contract for Project REG, or our contracts with third parties that relate to projects for the U.S. government will not be terminated or suspended in the future. The U.S. government’s termination of, or failure to fully fund, one or more of our contracts would have a negative impact on our operating results and financial condition. Further, in the event that any of our government contracts are terminated for cause, it could affect our ability to obtain future government contracts which could, in turn, seriously harm our ability to develop our technologies and products.

The novel coronavirus (COVID-19) pandemic could adversely impact our business, financial condition and results of operations.

In March 2020, the World Health Organization declared the disease caused by the novel coronavirus ("COVID-19") to be a pandemic. COVID-19 has spread throughout the globe, including in the Commonwealth of Massachusetts where our headquarters are located, and in other areas where we have business operations. In response to the outbreak, we have followed the guidelines of the U.S. Centers for Disease Control and Prevention ("CDC") and applicable state government authorities to protect the health and safety of our employees, their families, our suppliers, our customers and our communities. While these existing measures, and COVID-19 generally, have not materially disrupted our business to date, any future actions necessitated by the COVID-19 pandemic may result in disruption to our business.  

Our suppliers may become adversely impacted by the COVID-19 pandemic. As a result, we could face delays or difficulty sourcing products, which could negatively affect our business and financial results. Even if we are able to find alternate sources for such products, they may cost more, which could adversely impact our profitability and financial condition.

Inox’s ability to perform under the supply contract has been and may continue to be hampered by the prolonged impacts of the COVID-19 pandemic.  Our other customers may become adversely impacted by the prolonged impacts of the COVID-19 pandemic. As a result of the deterioration in economic conditions, our customers and potential customers may reduce demand for our products, decrease their spending or reconsider orders, all of which would adversely affect our business, operating results and financial condition. 

The COVID-19 pandemic continues to rapidly evolve. The extent to which the outbreak impacts our business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including new information which may emerge concerning the severity of the COVID-19 pandemic and the actions to contain it or treat its impact, among others. If we, our customers or suppliers experience prolonged shutdowns or other business disruptions, our business, liquidity, results of operations and financial condition and the trading price of our common stock are likely to be materially adversely affected, and our ability to access the capital markets may be limited.

We rely upon third-party suppliers for the components and subassemblies of many of our Grid and Wind products, making us vulnerable to supply shortages and price fluctuations, which could harm our business.

Many of our components and subassemblies are currently manufactured for us by a limited number of qualified suppliers. Any interruption in the supply of components or subassemblies, or our inability to obtain substitute components or subassemblies from alternate sources at acceptable prices in a timely manner, could impair our ability to meet the demand of our customers, which would have an adverse effect on our business and operating results.

We are producing certain Wind products in our manufacturing facility in Romania. In order to minimize costs and time to market, we have and will continue to identify local suppliers that meet our quality standards to produce certain of our subassemblies and components. These efforts may not be successful. In addition, any event which negatively impacts our supply, including, among others, wars, terrorist activities, natural disasters and outbreaks of infectious disease, including the COVID-19 pandemic, could delay or suspend shipments of products or the release of new products or could result in the delivery of inferior products. Our revenues from the affected products would decline or we could incur losses until such time as we are able to restore our production processes or put in place alternative contract manufacturers or suppliers. Even though we carry business interruption insurance policies, we may suffer losses as a result of business interruptions that exceed the coverage available under our insurance policies.

Our financial condition may have an adverse effect on our customer and supplier relationships.

Our relationships with our customers and suppliers are predicated on the belief that we will continue to operate. Our customers, particularly in the utility industry, are generally risk averse and may not enter into sales contracts with us if there is uncertainty regarding our ability to support working capital needs of large-scale projects.  

We may experience difficulties re-establishing our HTS wire production capability in our Ayer, Massachusetts facility.

As part of our effort to increase manufacturing efficiency, we moved from our former manufacturing facility located in Devens, Massachusetts to our smaller-scale leased facility located in Ayer, Massachusetts. Moving our HTS wire manufacturing operations to a different plant involves various risks, including the inability to commence HTS wire manufacturing within the cost and time frame estimated and the inability to produce a high-quality product with an acceptable yield and cost.  Failure to successfully commence the manufacturing of our HTS wire due to these and other unforeseen risks could adversely affect our ability to meet customer demand for our products and could increase the cost of production versus projections, both of which could adversely impact our operating and financial results.

Our success is dependent upon attracting and retaining qualified personnel and our inability to do so could significantly damage our business and prospects.

We have attracted a highly skilled management team and specialized workforce, including scientists, engineers, researchers, manufacturing, personnel, and marketing and sales professionals. Hiring and retaining good personnel for our business is challenging, and highly qualified technical personnel are likely to remain a limited resource for the foreseeable future. We may not be able to hire the necessary personnel to implement our business strategy.  In addition, we may need to provide higher compensation or more training to our personnel than we currently anticipate. Moreover, any officer or employee can terminate his or her relationship with us at any time.  Losing the services of any of our executive officers or key employees could materially and adversely impact our business.

14

Historically, a significant portion of our revenues have been derived from a single customer. If this customer’s business is negatively affected, it could adversely impact our business.

Our largest customer in two of the last three years has been Inox in India.  Inox accounted for less than 10% of our total revenues during the fiscal year ended March 31, 2020 and 34% of our total revenues during the fiscal year ended March 31, 2019. Revenues from Inox are supported by a supply contract to purchase, and a license to make, use and supply, wind turbine ECS.  Inox has been active in the new central and state government auction regime in India and has over 900 MW of orders from the first four Solar Energy Corporation of India Limited (“SECI”) central government auctions, and 50 MW from the Maharashtra state government auction. However, we cannot predict if and how successful Inox will be in executing on these orders or in obtaining new orders under the new central and state auction regime.  In addition, Inox’s ability to perform under the supply contract has been and may continue to be hampered by the prolonged impacts of the COVID-19 pandemic. Since March 2020, India’s manufacturing facilities have been closed at the direction of India’s government and are expected to remain closed for so long as the impacted regions remain highly affected by COVID-19.  Any failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer ECS shipments to Inox.  Inox is currently delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On May 29, 2020, we sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox fails to post letters of credit in the amount of €6.0 million in accordance with the terms of the supply contract within the ninety-day cure period after receipt of the default notice, then we may terminate the supply contract by providing written notice of such termination to Inox.  If we were to terminate the supply contract with Inox, we could have to write-off some or all of the inventory related to the supply contract, which could harm our business, operating results and financial position.   We cannot predict if and when Inox will post letters of credit consistent with the forecasted ECS quantities. If Inox continues to fail to post letters of credit and take delivery of forecasted ECS quantities, cancels, does not otherwise fully perform under the supply contract or discontinues future purchases from us under the supply contract, then our business, operating results and financial position could be adversely affected.

Our success in addressing the wind energy market is dependent on the manufacturers that license our designs.

Because an important element of our strategy for addressing the wind energy market involves the license of our wind turbine designs to manufacturers of those systems, the financial benefits to us from our products for the wind energy market are dependent on the success of these manufacturers in selling wind turbines based on our designs. We may not be able to enter into marketing or distribution arrangements with third parties on financially acceptable terms, or at all, and third parties may not be successful in selling our products or applications incorporating our products.

Our business and operations would be adversely impacted in the event of a failure or security breach of our information technology infrastructure.

We rely upon the capacity, reliability, and security of our information technology hardware and software infrastructure and our ability to expand and update this infrastructure in response to our changing needs. Any failure to manage, expand, and update our information technology infrastructure or any failure in the operation of this infrastructure could harm our business.  In addition, the costs associated with updating and securing our information technology infrastructure are likely to increase as such security measures become more complex, which may harm our operating results and financial condition.

Despite our implementation of security measures, our systems are vulnerable to damages from computer viruses, natural disasters, unauthorized access and other similar disruptions. Our business is also subject to break-ins, sabotage, and intentional acts of vandalism by third parties as well as employees. Our business activities in China may increase our risks to such breaches. Any system failure, accident, or security breach could result in disruptions to our operations. To the extent that any disruption or security breach results in a loss or damage to our data, or inappropriate disclosure of confidential information, it could harm our reputation, result in substantial remediation costs, lead to lost revenues and litigation, increase our insurance premiums and have other adverse effects on our business.

Failure to comply with evolving data privacy and data protection laws and regulations or to otherwise protect personal data, may adversely impact our business and financial results.

We are subject to many rapidly evolving privacy and data protection laws and regulations in Europe and around the world.  This requires us to operate in a complex environment where there are significant constraints on how we can process personal data across our business. The European General Data Protection Regulation (the “GDPR”), which became effective in May 2018, has established stringent data protection requirements for companies doing business in or handling personal data of individuals in the European Union. The GDPR imposes obligations on data controllers and processors including the requirement to maintain a record of their data processing and to implement policies and procedures as part of their mandated privacy governance framework. Breaches of the GDPR could result in substantial fines, which in some cases could be up to four percent of our worldwide revenue. In addition, a breach of the GDPR or other data privacy or data protection laws or regulations could result in regulatory investigations, reputational damage, orders to cease/change our use of data, enforcement notices, as well potential civil claims including class action type litigation. There is a risk that we may be subject to fines and penalties, litigation and reputational harm if we fail to properly process or protect the data or privacy of third parties or comply with the GDPR or other applicable data privacy and data protection regimes.

Many of our revenue opportunities are dependent upon subcontractors and other business collaborators.

Many of the revenue opportunities for our business involve projects, such as the installation of superconductor cables in power grids and electrical system hardware in wind turbines, in which we collaborate with other companies, including suppliers of cryogenic systems, manufacturers of electric power cables and manufacturers of wind turbines. As a result, most of our current and planned revenue-generating projects involve business collaborators on whose performance our revenue is dependent. If these business collaborators fail to deliver their products or perform their obligations on a timely basis or fail to generate sufficient demand for the systems they manufacture, our revenue from the project may be delayed or decreased, and we may not be successful in selling our products.

If we fail to implement our business strategy successfully, our financial performance could be harmed.

Our future financial performance and success are dependent in large part upon our ability to implement our business strategy successfully. Our business strategy envisions several initiatives, including driving revenue growth and enhancing operating results by increasing customer adoption of our products by targeting high-growth segments with commercial and system-level products. We may not be able to implement our business strategy successfully or achieve the anticipated benefits of our business plan. If we are unable to do so, our long-term growth and profitability may be adversely affected. Even if we are able to implement some or all of the initiatives of our business plan successfully, our operating results may not improve to the extent we anticipate, or at all. In addition, to the extent we have misjudged the nature and extent of industry trends or our competition, we may have difficulty in achieving our strategic objectives. Any failure to implement our business strategy successfully may adversely affect our business, financial condition and results of operations. In addition, we may decide to alter or discontinue certain aspects of our business strategy at any time.

Our ability to implement our business strategy could also be affected by a number of factors beyond our control, such as increased competition, legal developments, government regulation, general economic conditions, including as a result of the COVID-19 pandemic, or increased operating costs or expenses.

Problems with product quality or product performance may cause us to incur warranty expenses and may damage our market reputation and prevent us from achieving increased sales and market share.

Consistent with customary practice in our industry, we guarantee our products and/or services to be free from defects in material and workmanship under normal use and service. We generally provide a one- to three-year warranty on our products, commencing upon installation. A provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based on historical experience. The possibility of future product failures or issues related to services we provided could cause us to incur substantial expenses to repair or replace defective products or re-perform such services potentially in excess of our reserves. Furthermore, widespread product failures may damage our market reputation and reduce our market share and cause sales to decline.

Many of our customers outside of the United States may be either directly or indirectly related to governmental entities, and we could be adversely affected by violations of the United States Foreign Corrupt Practices Act and similar worldwide anti-bribery laws outside the United States.

The U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Many of our customers outside of the United States are, either directly or indirectly, related to governmental entities and are therefore subject to such anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on our business, results of operations and financial condition.

We have had limited success marketing and selling our superconductor products and system-level solutions, and our failure to more broadly market and sell our products and solutions could lower our revenue and cash flow.

To date, we have had limited success marketing and selling our superconductor products and system-level solutions. Once our products and solutions are ready for widespread commercial use, we will have to develop a marketing and sales organization that will effectively demonstrate the advantages of our products over more traditional products, competing superconductor products and other technologies. We may not be successful in our efforts to market this technology and we may not be able to establish an effective sales and distribution organization.

We may decide to enter into arrangements with third parties for the marketing or distribution of our products, including arrangements in which our products, such as Amperium wire, are included as a component of a larger product, such as a power cable system. By entering into marketing and sales alliances, the financial benefits to us of commercializing our products will be dependent on the efforts of others.

We may acquire additional complementary businesses or technologies, which may require us to incur substantial costs for which we may never realize the anticipated benefits.

Our prior acquisitions required substantial integration and management efforts. As a result of any acquisition we pursue, management’s attention and resources may be diverted from our other businesses. An acquisition may also involve the payment of a significant purchase price, which could reduce our cash position or dilute our stockholders and require significant transaction-related expenses.

Achieving the benefits of any acquisition involves additional risks, including:

• difficulty assimilating acquired operations, technologies and personnel;

• inability to retain management and other key personnel of the acquired business;

• changes in management or other key personnel that may harm relationships with the acquired business’s customers and employees;

• unforeseen liabilities of the acquired business;

• diversion of management’s and employees’ attention from other business matters as a result of the integration process;

• mistaken assumptions about volumes, revenue and costs associated with the acquired business, including synergies;

• limitations on rights to indemnity from the seller;

• mistaken assumptions about the overall costs of equity or debt used to finance the acquisition; and

• unforeseen difficulties operating in new product areas, with new customers, or in new geographic areas.

We cannot provide any assurance that we will realize any of the anticipated benefits of any acquisition, and if we fail to realize these anticipated benefits, our operating performance could suffer.

16

Risks Related to Our Markets

Our success depends upon the commercial adoption of the REG system, which is currently limited, and a widespread commercial market for our products may not develop.

To date, there has been no widespread commercial use of the REG system. It is uncertain whether a robust commercial market for those new and unproven products will ever develop.

In addition, we believe in-grid demonstrations of REG systems are necessary to convince utilities and power grid operators of the benefits of this technology. Even if a project is funded, completion of projects can be delayed as a result of other factors.  It is possible that the market demands we currently anticipate for our REG system will not develop and that they will never achieve widespread commercial acceptance. In such event, we would not be able to implement our strategy, and our profits could be reduced or eliminated.  Even if a commercial market for our REG systems were to develop, commercial terms requested by utilities and power grid operators relating to bonding requirements, limitations of liability, warranty periods, or other contractual provisions, may not be acceptable to us, which could impede our ability to enter into contractual arrangements for the sale of our REG system.

Adverse changes in domestic and global economic conditions could adversely affect our operating results.

We have become increasingly subject to the risks arising from adverse changes in domestic and global economic conditions. In recent years, and particularly in 2020 as a result of the COVID-19 pandemic, the state of both the domestic and global economies has been uncertain due to the difficulty in obtaining credit, and financial market volatility. Adverse credit conditions in the future could have a negative impact on our ability to execute on future strategic activities.  In addition, if credit is difficult to obtain in the future, some customers may delay or reduce purchases. This could result in reductions in sales of our products, longer sales cycles, slower adoption of new technologies, increased accounts receivable and inventory write-offs and increased price competition. Any of these events would likely harm our business, results of operations and financial condition.

We have operations in, and depend on sales in, emerging markets, including India, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of these markets. Changes in India’s political, social, regulatory and economic environment may affect our financial performance.

We have operations in India and in recent years a significant portion of our total revenues has been derived from customers in this market.  Our financial performance depends upon our ability to carry on our operations and sell our products in markets such as India, as well as other emerging markets around the world.  We are, and will continue to be, subject to financial, political, economic and business risks in connection with our operations and sales in these emerging markets. In addition to the business risks inherent in developing and servicing these markets, economic conditions may be more volatile, legal and regulatory systems less developed and predictable, and the possibility of various types of adverse governmental action more pronounced in emerging markets. In addition, inflation, fluctuations in currency and interest rates, competitive factors, civil unrest and labor problems could affect our revenues, expenses and results of operations. Our operations could also be adversely affected by acts of war, terrorism or the threat of any of these events as well as government actions such as controls on imports, exports and prices, tariffs, new forms of taxation, or changes in fiscal regimes and increased government regulation in the countries in which we operate or service customers. Unexpected or uncontrollable events or circumstances in any of these markets could have a material adverse effect on our financial results and cash flows.

Our financial performance could be affected by the political and social environment in India.  In recent years, India has experienced civil unrest and terrorism and has been involved in conflicts with neighboring countries.  The potential for hostilities between India and Pakistan has been high in light of tensions related to recent terrorist incidents in India and the unsettled nature of the regional geopolitical environment, including events in and related to Afghanistan and Iraq.

With respect to our activities in all emerging markets, we may be impacted by issues with managing foreign sales operations, including long payment cycles, potential difficulties in accounts receivable collection and, especially from significant customers, fluctuations in the timing and amount of orders. The adverse effect of any of these issues on our business could be increased due to the concentration of our business with a small number of customers. Operations in foreign countries also expose us to risks relating to difficulties in enforcing our proprietary rights, currency fluctuations and adverse or deteriorating economic conditions. If we experience problems with obtaining registrations, compliance with foreign country or applicable U.S. laws, or if we experience difficulties in payments or intellectual property matters in foreign jurisdictions, or if significant political, economic or regulatory changes occur, our results of operations would be adversely affected.

17

Our products face competition, which could limit our ability to acquire or retain customers.

The markets for our products are competitive and many of our competitors have substantially greater financial resources and research and development, manufacturing and marketing capabilities than we do. In addition, as our target markets develop, other large industrial companies may enter these fields and compete with us.

We face competition from other companies offering FACTS systems similar to our D-VAR products. These include adaptive VAR compensators, Dynamic voltage restorers (“DVRs”), and STATCOMs produced by ABB, Siemens, RXHK, NR Electric Co,. and Ingeteam, and battery-based uninterruptible power supply (“UPS”) systems offered by various companies around the world.

With our HTS-based REG product, we are offering a new approach that provides alternatives to utilities for power system design. Therefore, we believe that we compete with traditional approaches such as new full-sized substations, overhead and underground transmission, and urban power transformers.

We believe we are currently the only company that can offer HTS-based SPS products that have been fully qualified for use aboard U.S. Navy surface combatants.  Therefore, the primary competition for our SPS products is currently coming from defense contractors that provide the copper-based systems that our lighter, more efficient HTS versions have been developed to replace.  Companies such as L3, Excelis, Raytheon, and Textron have the bulk of the copper-based business today.

As the HTS wire, superconductor electric motors and generators, and power electronic systems markets develop, other large industrial companies may enter those fields and compete with us. If we are unable to compete successfully, it may harm our business, which in turn may limit our ability to acquire or retain customers.

With respect to our Wind business, other companies that serve the wind turbine components industry include ABB, Hopewind, and Semikron. We also face indirect competition in the wind energy market from global manufacturers of wind turbines, such as Siemens Gamesa, General Electric, and Suzlon. We face competition for the supply of wind turbine engineering design services from design engineering firms such as Aerodyn.

Our international operations are subject to risks that we do not face in the United States, which could have an adverse effect on our operating results.

In recent years, a substantial majority of our consolidated revenues were recognized from customers outside of the United States. For example, 51% of our revenues in fiscal 2019 and 74% of our revenues in fiscal 2018 were recognized from sales outside the United States.  We also manufacture certain of our products and purchase a portion of our raw materials and components from suppliers in other foreign countries. Our international operations are subject to a variety of risks that we do not face in the United States, including:

• potentially longer payment cycles for sales in foreign countries and difficulties in collecting accounts receivable;

• difficulties in staffing and managing our foreign offices and the increased travel, infrastructure and legal compliance costs associated with multiple international locations;

• additional withholding taxes or other taxes on our foreign income and repatriated cash, and tariffs or other restrictions on foreign trade or investment, including export duties and quotas, trade and employment restrictions;

• imposition of, or unexpected adverse changes in, foreign laws or regulatory requirements;

• increased exposure to foreign currency exchange rate risk;

• reduced protection for intellectual property rights in some countries; and

• natural disasters, pandemics, political unrest, war or acts of terrorism.

In addition, the current U.S. presidential administration has withdrawn the United States from the Trans-Pacific Partnership trade agreement, renegotiated the North American Free Trade Agreement, and has made various comments suggesting the possible re-negotiation of or withdrawal from other trade agreements and the potential imposition of new import barriers. Trade tensions between the U.S. and China, as well as those between the U.S. and Canada, Mexico and other countries have been escalating in recent years. For example, the U.S. administration has imposed tariffs on products imported from China in recent years, which had an impact on our products and supplies imported from China to the U.S., and the Chinese government countered with additional retaliatory tariffs on U.S. manufactured goods. We cannot predict whether the United States or any other country will impose new quotas, tariffs, taxes or other trade barriers upon the importation or exportation of our products or gauge the effect that new barriers would have on our financial position or results of operations.  These new tariffs or any additional tariffs or other trade barriers may cause our costs to increase, our products to be less competitive, and our business, results of operations and financial position to be materially adversely affected.

Our overall success in international markets depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we do business or conduct operations. Our failure to manage these risks successfully could harm our international operations and reduce our international sales, thus lowering our total revenue and reducing or eliminating our profits.

Growth of the wind energy market depends largely on the availability and size of government subsidies, economic incentives and legislative programs designed to support the growth of wind energy.

At present, the cost of wind energy exceeds the cost of conventional power generation in many locations around the world. Various governments have used different policy initiatives to encourage or accelerate the development and adoption of wind energy and other renewable energy sources. Renewable energy policies are in place in the European Union, certain countries in Asia, including India, China, Japan and South Korea, and many of the states in Australia and the United States. Examples of government sponsored financial incentives include capital cost rebates, feed-in tariffs, tax credits, net metering and other incentives to end-users, distributors, system integrators and manufacturers of wind energy products to promote the use of wind energy and to reduce dependency on other forms of energy. In the United States, various legislation and regulations designed to support the growth of wind energy have been implemented or proposed by the federal government, such as the Production Tax Credit for Renewable Energy (“PTC”) and the Clean Power Plan. Governments, including the U.S. government, may decide to reduce or eliminate these economic incentives, or curtail legislative programs supportive of wind energy technologies for political, financial or other reasons. Any reductions in, or eliminations of, government subsidies, economic incentives or favorable legislative programs before the wind energy industry reaches a sufficient scale to be cost-effective in a non-subsidized marketplace could reduce demand for our products and adversely affect our business prospects and results of operations.

Lower prices for other fuel sources may reduce the demand for wind energy development, which could have a material adverse effect on our ability to grow our Wind business.

The wind energy market is affected by the price and availability of other fuels, including nuclear, coal, natural gas and oil, as well as other sources of renewable energy. To the extent renewable energy, particularly wind energy, becomes less cost-competitive due to reduced government targets, increases in the cost of wind energy, as a result of new regulations, and incentives that favor alternative renewable energy, cheaper alternatives or otherwise, demand for wind energy and other forms of renewable energy could decrease. Slow growth or a long-term reduction in the demand for renewable energy could have a material adverse effect on our ability to grow our Wind business.

Unfavorable results of legal proceedings could have a material adverse effect on our business, operating results and financial condition.

From time to time, we may become subject to legal proceedings and claims that arise in or outside the ordinary course of business. Results of legal proceedings cannot be predicted with certainty. Our insurance coverage may be insufficient, our assets may be insufficient to cover any amounts that exceed our insurance coverage, and we may have to pay damage awards or otherwise may enter into settlement arrangements in connection with such claims. Any such payments or settlement arrangements in legal proceedings could have a material adverse effect on our business, operating results or financial condition. Regardless of merit, legal proceedings could result in substantial costs and significantly and adversely impact our reputation and divert management’s attention and resources, which could have a material adverse effect on our business, operating results or financial condition. In addition, such lawsuits may make it more difficult to finance our operations.

Risks Related to Our Technologies

We may be unable to adequately prevent disclosure of trade secrets and other proprietary information.

We rely on trade secrets to protect our proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely, in part, on confidentiality agreements with our employees, contractors, consultants, outside scientific collaborators and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets or independently develop processes or products that are similar or identical to our trade secrets and courts outside the United States may be less willing to protect trade secrets. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

Our patents may not provide meaningful protection for our technology, which could result in us losing some or all of our market position.

We own or have licensing rights under many patents and pending patent applications. However, the patents that we own or license may not provide us with meaningful protection of our technologies and may not prevent our competitors from using similar technologies for a variety of reasons, such as:

• the patent applications that we or our licensors file may not result in patents being issued;

• any patents issued may be challenged by third parties; and

• others may independently develop similar technologies not protected by our patents or design around the patented aspects of any technologies we develop.

Moreover, we could incur substantial litigation costs in defending the validity of or enforcing our own patents. We also rely on trade secrets and proprietary know-how to protect our intellectual property. However, our non-disclosure agreements and other safeguards may not provide meaningful protection for our trade secrets and other proprietary information. If the patents that we own or license or our trade secrets and proprietary know-how fail to protect our technologies, our market position may be adversely affected.

There are a number of technological challenges that must be successfully addressed before our superconductor products can gain widespread commercial acceptance, and our inability to address such technological challenges could adversely affect our ability to acquire customers for our products.

Many of our superconductor products are in the early stages of commercialization, while others are still under development. There are a number of technological challenges that we must successfully address to complete our development and commercialization efforts for superconductor products. We will also need to improve the performance and reduce the cost of our Amperium wire to expand the number of commercial applications for it. We may be unable to meet such technological challenges or to sufficiently improve the performance and reduce the costs of our Amperium wire. Delays in development, as a result of technological challenges or other factors, may result in the introduction or commercial acceptance of our superconductor products later than anticipated.

19

Third parties have or may acquire patents that cover the materials, processes and technologies we use or may use in the future to manufacture our Amperium products, and our success depends on our ability to license such patents or other proprietary rights.

We expect that some or all of the HTS materials, processes and technologies we use in designing and manufacturing our products are or will become covered by patents issued to other parties, including our competitors. The owners of these patents may refuse to grant licenses to us, or may be willing to do so only on terms that we find commercially unreasonable. If we are unable to obtain these licenses, we may have to contest the validity or scope of those patents or re-engineer our products to avoid infringement claims by the owners of these patents. It is possible that we will not be successful in contesting the validity or scope of a patent, or that we will not prevail in a patent infringement claim brought against us. Even if we are successful in such a proceeding, we could incur substantial costs and diversion of management resources in prosecuting or defending such a proceeding.

Our technology and products could infringe intellectual property rights of others, which may require costly litigation and, if we are not successful, could cause us to pay substantial damages and disrupt our business.

In recent years, there has been significant litigation involving patents and other intellectual property rights in many technology-related industries. There may be patents or patent applications in the United States or other countries that are pertinent to our products or business of which we are not aware. The technology that we incorporate into and use to develop and manufacture our current and future products, including the technologies we license, may be subject to claims that they infringe the patents or proprietary rights of others. The success of our business will also depend on our ability to develop new technologies without infringing or misappropriating the proprietary rights of others. Third parties may allege that we infringe patents, trademarks or copyrights, or that we misappropriated trade secrets. These allegations could result in significant costs and diversion of the attention of management. If a successful claim were brought against us and we are found to infringe a third party’s intellectual property rights, we could be required to pay substantial damages, including treble damages if it is determined that we have willfully infringed such rights, or be enjoined from using the technology deemed to be infringing, or using, making or selling products deemed to be infringing. If we have supplied infringing products or technology to third parties, we may be obligated to indemnify these third parties for damages they may be required to pay to the patent holder and for any losses they may sustain as a result of the infringement. In addition, we may need to attempt to license the intellectual property right from such third party or spend time and money to design around or avoid the intellectual property. Any such license may not be available on reasonable terms, or at all. An adverse determination may subject us to significant liabilities and/or disrupt our business.

Risks Related to Our Common Stock

Our common stock has experienced, and may continue to experience, market price and volume fluctuations, which may prevent our stockholders from selling our common stock at a profit and could lead to costly litigation against us that could divert our management’s attention.

The market price of our common stock has historically experienced volatility and may continue to experience such volatility in the future. Factors such as our financial performance, liquidity requirements, technological achievements by us and our competitors, the establishment of development or strategic relationships with other companies, strategic acquisitions, new customer orders and contracts, and our introduction of commercial products may have a significant effect on the market price of our common stock. The stock market in general, and the stock of high technology companies, in particular, have, in recent years, experienced extreme price and volume fluctuations, which are often unrelated to the performance or condition of particular companies, such as in connection with the ongoing coronavirus outbreak. Such broad market fluctuations have and could continue to adversely affect the market price of our common stock. Due to these factors, the price of our common stock may decline, and investors may be unable to resell their shares of our common stock for a profit. Following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against that company. In the past, we have been subject to a number of class action lawsuits which were filed against us on behalf of certain purchasers of our common stock. If we become subject to additional litigation of this kind in the future, it could result in additional litigation costs, a damages award against us and the further diversion of our management’s attention.

Item 7. MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Overview

We are a leading system provider of megawatt-scale power resiliency solutions that orchestrate the rhythm and harmony of power on the grid, and that protect and expand the capability of our Navy's fleet. Our solutions enhance the performance of the power grid, protect our Navy’s fleet, and lower the cost of wind power.  In the power grid market, we enable electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through our transmission planning services and power electronics and superconductor-based systems. In the wind power market, we enable manufacturers to field highly competitive wind turbines through our advanced power electronics and control system products, engineering, and support services. Our power grid and wind products and services provide exceptional reliability, security, efficiency and affordability to our customers.

Our power system solutions help to improve energy efficiency, alleviate power grid capacity constraints, improve system resiliency, and increase the adoption of renewable energy generation. Demand for our solutions is driven by the growing needs for modernized smart grids that improve power reliability, security and quality, the U.S. Navy's effort to upgrade in-board power systems to support fleet electrification, and the need for increased renewable sources of electricity, such as wind and solar energy. Concerns about these factors have led to increased spending by corporations and the military, as well as supportive government regulations and initiatives on local, state, and national levels, including renewable portfolio standards, tax incentives and international treaties.  

We manufacture products using two proprietary core technologies: PowerModule programmable power electronic converters and our Amperium high temperature superconductor (HTS) wires. These technologies and our system-level solutions are protected by a broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.

We operate our business under two market-facing business units: Grid and Wind. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of power generation project developers, the Navy's ship protection systems, electric utilities and wind turbine manufacturers.

• Grid. Through our Gridtec Solutions™, our Grid business segment enables electric utilities and renewable energy project developers to connect, transmit and distribute power with exceptional efficiency, reliability, security and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality, and other risks, which help us determine how our solutions can improve network performance. These services often lead to sales of our grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems.  We also sell ship protection products to the U.S. Navy through our Grid business segment.

• Wind. Through our Windtec Solutions™, our Wind business segment enables manufacturers to field wind turbines with exceptional power output, reliability and affordability. We supply advanced power electronics and control systems, license our highly engineered wind turbine designs, and provide extensive customer support services to wind turbine manufacturers. Our design portfolio includes a broad range of drivetrains and power ratings of 2 MW and higher. We provide a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the fiscal year beginning on April 1 of that same year. For example, fiscal 2019 refers to the fiscal year beginning on April 1, 2019. Other fiscal years follow similarly.

On July 3, 2018, we and our wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GmbH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settled the previously disclosed litigation and arbitration proceedings between us and Sinovel (the “Proceedings”), and any other civil claims, counterclaims, causes of action, rights and obligations directly or indirectly relating to the subject matters of the Proceedings and our contracts with Sinovel (the “Contracts”), subject to certain exceptions. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018 and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018.

On October 31, 2018, we entered into a Subcontract Agreement with Commonwealth Edison Company (“ComEd”) (the “Subcontract Agreement”) for the manufacture and installation of our resilient electric grid (“REG”) system within ComEd’s electric grid in Chicago, Illinois (the “Project”). As provided in the Subcontract Agreement, the Subcontract Agreement became effective upon the signing of an amendment by us and the U.S. Department of Homeland Security (“DHS”) to the existing contract (the “Prime Contract”) between ourselves and DHS on June 20, 2019. Unless terminated earlier by us, ComEd or DHS according to the terms of the Subcontract Agreement, the term of the Subcontract Agreement will continue until we complete our warranty obligations under the Subcontract Agreement. Under the terms of the Subcontract Agreement, we have agreed, among other things, to provide the REG system and to supervise ComEd’s installation of the REG system in Chicago. As part of our separate cost sharing arrangement with DHS under the Prime Contract, we expect funding provided by DHS in connection with the Subcontract Agreement to be between $9.0 to $11.0 million, which represents the total amount of revenues we are expected to recognize over the term of the Subcontract Agreement and includes up to $1.0 million that we have agreed to reimburse ComEd for costs incurred by ComEd while undertaking its tasks under the Subcontract Agreement (the "Reimbursement Amount”). In addition, we have agreed to deliver an irrevocable letter of credit in the amount of $5.0 million to secure certain obligations under the Subcontract Agreement, which we have done, and deposited $5.0 million in an escrow account as collateral to secure such letter of credit. ComEd has agreed to provide the site and provide all civil engineering work required to support the installation, operation and integration of the REG system into ComEd’s electric grid. Other than the Reimbursement Amount, ComEd is responsible for its own costs and expenses. Substation work on the project began in late 2019 and we are on schedule to deliver the REG project hardware in late 2020.  The REG system is expected to be operational in 2021.

In March 2020, the World Health Organization declared the disease caused by the novel coronavirus (“COVID-19“) to be a pandemic. COVID-19 has spread throughout the globe, including in the Commonwealth of Massachusetts where our headquarters are located, and in other areas where we have business operations. In response to the outbreak, we have followed the guidelines of the U.S. Centers for Disease Control and Prevention (“CDC”) and applicable state government authorities to protect the health and safety of our employees, their families, our suppliers, our customers and our communities. While these existing measures and, COVID-19 generally, have not materially disrupted our business to date, any future actions necessitated by the COVID-19 pandemic may result in disruption to our business.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the outbreak impacts our business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including new information that may emerge concerning the severity of the COVID-19 pandemic and the actions to contain it or treat its impact, among others.

Results of Operations

Fiscal Years Ended March 31, 2020 and March 31, 2019

For a discussion of our results of operations for the year ended March 31, 2018, including a year-to-year comparison between fiscal 2018 and fiscal 2017, refer to Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended March 31, 2019.

Revenues

Total revenues increased by 14% to $63.8 million in fiscal 2019 from $56.2 million in fiscal 2018. Our revenues are summarized as follows (in thousands):

	Fiscal Years Ended March 31,
	2020		2019
Revenues:
Grid	$	49,585	$	34,290
Wind		14,253		21,917
Total	$	63,838	$	56,207

Revenues in our Grid business unit are derived from our D-VAR product sales, HTS wire sales, ship protection systems ("SPS"), government-sponsored electric utility projects, license contracts and other prototype development contracts. We also engineer, install and commission our products on a turnkey-basis for some customers. The Grid business unit accounted for 78% of total revenues in fiscal 2019 and 61% in fiscal 2018. Grid revenue increased 45% to $49.6 million in fiscal 2019 from $34.3 million in fiscal 2018.  The increase in revenue was driven by growth in all four grid product lines, D-VAR, Volt Var Optimization ("VVO"), Resilient Electric Grid ("REG") and SPS.

Revenues in our Wind business unit are derived from wind turbine electrical control systems and core components, wind turbine license and development contracts, service contracts and consulting arrangements. Our Wind business unit accounted for 22% of total revenues in fiscal 2019 and 39% in fiscal 2018. Revenues in the Wind business unit decreased 35% to $14.3 million in fiscal 2019 from $21.9 million in fiscal 2018.  The decreases over the prior year period were driven by decreased shipments of Electrical Control Systems ("ECS") to Inox offset partially by shipments of ECS to Doosan.  As further described in Note 1 “Nature of the Business and Operations and Liquidity,” Inox is currently delinquent on its obligations to post letters of credit for sets of electrical control systems that Inox has agreed to purchase under the terms of the supply contract, and on May 29, 2020, we sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract. If Inox fails to post letters of credit in the amount of €6.0 million in accordance with the terms of the supply contract within the ninety-day cure period after receipt of the default notice, then the Company may terminate the supply contract by providing written notice of such termination to Inox.  In addition, Inox’s ability to perform under the supply contract has been and may continue to be hampered by the prolonged impacts of the COVID-19 pandemic. Since March 2020, India’s manufacturing facilities have been closed at the direction of India’s government and are expected to remain closed for so long as the impacted regions remain highly affected by COVID-19.  We cannot predict if and when Inox will resume posting letters of credit for payment of contracted-for shipments of electrical control systems. Inox's continued failure to post letters of credit and take delivery of contracted-for shipments of electrical control shipments has negatively impacted, and could continue to negatively impact, our revenues and liquidity.  In the event we were to terminate the supply contract, our revenues and liquidity could also be negatively impacted.  Inox has been active in the new central and state government auction regime in India and has over 900 MW of orders from the first four SECI central government auctions, and 50 MW from the Maharashtra state government auction. However, we cannot predict if and how successful Inox will be in executing on these orders or in obtaining new orders under the new central and state auction regime. Any failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer ECS shipments to Inox.

Cost of Revenues and Gross Margin

Cost of revenues increased by 29% to $54.4 million in fiscal 2019, compared to $42.2 million in fiscal 2018. Gross margin decreased to 15% in fiscal 2019 from 25% in fiscal 2018. The decrease in gross margin in fiscal 2019 was driven primarily by a less favorable product mix.

Operating Expenses

Research and development

Research and development (“R&D”) expenses decreased by 3% to $9.6 million, or 15% of revenue in fiscal 2019, compared to $9.9 million, or 18% of revenue, in fiscal 2018.  The decrease in R&D expenses is primarily the result of lower engineering supplies.

Selling, general, and administrative

Selling, general and administrative (“SG&A”) expenses increased by 3% to $22.7 million, or 36% of revenue in fiscal 2019 from $22.0 million, or 39% of revenue, in fiscal 2018. The increase in SG&A expenses is primarily the result of higher compensation cost due to increased headcount.

Gain on Sinovel settlement

We recorded a gain of $52.7 million, net of legal and other direct costs, in the year ended March 31, 2019, as a result of the receipt of the payments from Sinovel required by the Settlement Agreement, described further above.

Amortization of acquisition related intangibles

We recorded $0.3 million in both fiscal 2019 and fiscal 2018 in amortization expense related to our core technology and know-how, and trade names and trademark intangible assets.

26

Restructuring

We recorded restructuring charges of $0.5 million in fiscal 2018 for facility exit costs as a result of the relocation of the corporate office that was announced as part of our April 4, 2017 approved restructuring plan.  There was no restructuring activity in fiscal 2019.

Operating income (loss)

Our operating income (loss) is summarized as follows (in thousands):

	Fiscal Years Ended March 31,
	2020			2019
Operating income (loss):
Grid	$	(13,508	)	$	(10,600	)
Wind		(7,699	)		48,103
Unallocated corporate expenses		(1,922	)		(3,480	)
Total	$	(23,129	)	$	34,023

The Grid segment generated operating losses of $13.5 million in fiscal 2019 and $10.6 million in fiscal 2018. The increase in operating loss for fiscal 2019 is driven by lower gross margins due to less favorable product mix and an increase in SG&A expenses.

The Wind segment generated operating losses of $7.7 million in fiscal 2019 and an operating income of $48.1 million in fiscal 2018. The decrease in operating income for fiscal 2019 was due to the receipt of the payments from Sinovel required by the Settlement Agreement in the prior fiscal year, as well as fewer shipments of ECS to Inox.  

Unallocated corporate expenses in fiscal 2019 consisted of stock-based compensation expense of $1.9 million. Unallocated corporate expenses in fiscal 2018 consisted of stock-based compensation expense of $3.0 million, and a restructuring charge of $0.5 million.

Change in fair value of warrants

The change in fair value of warrants resulted in a gain of $4.6 million in fiscal 2019 compared to a loss of $3.7 million in fiscal 2018.  The changes in the fair value were primarily due to changes in our stock price, which is a key valuation metric, as well as the exercise of warrants issued to Hercules Technology Growth Capital, Inc. (the “Hercules Warrants”) in June 2019 and the exercise and expiration of warrants issued to Hudson Bay Capital (the “Hudson Warrants”) in November 2019.

Gain on sale of minority interest

We recorded a gain on sale of minority interest of $0.1 million related to receipt of payment from the prior sale of Blade Dynamics in fiscal 2018, which was fully impaired prior to the time of its sale.  There was no minority interest activity in fiscal 2019.

Interest income, net

Interest income, net was $1.3 million in fiscal 2019 compared to interest income, net of $1.1 million for fiscal 2018. The increase in interest income, net, was driven primarily by higher cash balances in the first half of fiscal 2019.

Other income, net

Other income, net was $0.3 million in fiscal 2019, compared to other income, net of $1.6 million in fiscal 2018. The decrease in other income, net was due to foreign currency gains in fiscal 2018.

27

Income Taxes

We recorded an income tax expense of $0.2 million in fiscal 2019 compared to $6.4 million in fiscal 2018. The decrease in income tax expense was primarily due to the prior year repayment of previously reserved intercompany trade balances due to AMSC Austria from AMSC China, and a dividend paid in the prior fiscal year by AMSC Austria to the Company in the U.S.  following the Sinovel settlement.

Net (loss) income

Net loss was $17.1 million fiscal 2019, compared to net income of $26.8 million in fiscal 2018.  The increase in net loss was driven primarily by the receipt of the payments from Sinovel required by the Settlement Agreement in fiscal 2018 and no such payments in fiscal 2019.

Please refer to the “Risk Factors” section in Part I, Item 1A, for a discussion of certain factors that may affect our future results of operations and financial condition.

Non-GAAP Measures

Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States (“GAAP”). The non-GAAP measures included in this Form 10-K, however, should be considered in addition to, and not as a substitute for or superior to the comparable measure prepared in accordance with GAAP.

We define non-GAAP net loss as net loss before gain on sale of minority investments, gain on Sinovel settlement, net, stock-based compensation, amortization of acquisition-related intangibles, changes in fair value of warrants and contingent consideration, other non-cash or unusual charges, and the tax effect of adjustments indicated in the table below.  The tax effect of adjustments relates primarily to the gain on Sinovel settlement, net.  We believe non-GAAP net loss assists management and investors in comparing our performance across reporting periods on a consistent basis by excluding these non-cash charges and other items that we do not believe are indicative of our core operating performance. In addition, we use non-GAAP net loss as a factor to evaluate the effectiveness of our business strategies. A reconciliation of GAAP to non-GAAP net loss is set forth in the table below (in thousands, except per share data):

	Year ended March 31,
	2020			2019
Net (loss) income	$	(17,096	)	$	26,761
Gain on sale of interest in minority investments		—			(127	)
Gain on Sinovel settlement, net		—			(52,698	)
Stock-based compensation		1,922			3,030
Amortization of acquisition-related intangibles		340			340
Change in fair value of warrants		(4,648	)		3,725
Tax effect of adjustments, primarily related to Settlement		—			5,925
Non-GAAP net loss		(19,482	)		(13,044	)
Non-GAAP net loss per share	$	(0.93	)	$	(0.64	)
Weighted average shares outstanding - basic and diluted		20,985			20,335

We incurred non-GAAP net losses of $19.5 million or $0.93 per share for fiscal 2019, compared to $13.0 million, or $0.64 per share, for fiscal 2018. The increase in non-GAAP net loss in fiscal 2019 compared to fiscal 2018 was driven by a decrease in net income driven by lower gross margin, as well as slightly higher operating costs. 

For a description and reconciliation of our other non-GAAP financial measure, non-GAAP operating cash flow, see below under “Non-GAAP Financial Measure – Non-GAAP Operating Cash Flow.”

28

Liquidity and Capital Resources

We have experienced recurring operating losses and as of March 31, 2020 had an accumulated deficit of $978.6 million. 

Our cash requirements depend on numerous factors, including the successful completion of our product development activities, our ability to commercialize our REG and ship protection system solutions, the rate of customer and market adoption of our products, collecting receivables according to established terms, the continued availability of U.S. government funding during the product development phase of our superconductor-based products, whether Inox is successful in executing on SECI orders or in obtaining additional orders under the new central and state auction regime, and whether and to the extent that Inox fulfills its purchase obligations under our supply contract. We continue to closely monitor our expenses and, if required, expect to further reduce our operating and capital spending to enhance liquidity.

At March 31, 2020, we had cash, cash equivalents, marketable securities and restricted cash of $66.1 million, compared to $78.2 million at March 31, 2019, a decrease of $12.1 million. As of March 31, 2020, we had approximately $6.4 million of cash, cash equivalents, marketable securities and restricted cash in foreign bank accounts.  Our cash and cash equivalents, marketable securities and restricted cash are summarized as follows (in thousands):

	March 31, 2020		March 31, 2019
Cash and cash equivalents	$	24,699	$	77,483
Marketable securities		35,195		—
Restricted cash		6,165		715
Total cash, cash equivalents, marketable securities and restricted cash	$	66,059	$	78,198

Net cash (used in) provided by operating activities was ($16.5 million) and $42.7 million in fiscal 2019 and 2018, respectively.  The decrease in net cash provided by operations in fiscal 2019 compared to fiscal 2018 was due primarily to the receipt of the full amount of the Sinovel settlement in fiscal 2018 as well as the change in overall operating accounts since fiscal 2018. 

Net cash (used in) provided by investing activities was ($36.6 million) and $2.2 million in fiscal 2019 and 2018, respectively. The decrease in net cash provided by investing activities in fiscal 2019 compared to fiscal 2018 was due primarily to the purchase of our marketable securities in fiscal 2019.  

Net cash provided by (used in) financing activities was $5.8 million and ($0.3 million) in fiscal 2019 and 2018, respectively.  The increase in net cash provided by financing activities in fiscal 2019 compared to fiscal 2018 was primarily due to the proceeds from the exercise of the Hercules Warrant.  

At March 31, 2020, we had $5.7 million of restricted cash included in long-term assets and $0.5 million of restricted cash in short-term assets.  At March 31, 2019, we had $0.7 million of restricted cash included in long-term assets. These amounts included in restricted cash primarily represent deposits to secure surety bonds and letters of credit for various customer contracts. These deposits are held in interest bearing accounts.

We believe we have sufficient available liquidity to fund our operations and capital expenditures for the next twelve months. In addition, we may seek to raise additional capital, which could be in the form of loans, convertible debt or equity, to fund our operating requirements and capital expenditures. We have no outstanding warrants as of March 31, 2020. Our liquidity is highly dependent on our ability to increase revenues, including our ability to collect revenues under our agreements with Inox, control our operating costs, and our ability to raise additional capital, if necessary. There can be no assurance that we will be able to raise additional capital on favorable terms or at all, or execute on any other means of improving our liquidity as described above.  Additionally, the impact of the COVID-19 pandemic on the global financial markets may reduce our ability to raise additional capital, if necessary, which could negatively impact our liquidity.

Non-GAAP Financial Measure – Non-GAAP Operating Cash Flow

We define non-GAAP operating cash flow as operating cash flow before the Sinovel settlement (net of legal fees and expenses); tax effect of adjustments; and other unusual cash flows or items. We believe non-GAAP operating cash flow assists management and investors in comparing our operating cash flow across reporting periods on a consistent basis by excluding these non-recurring cash items that it does not believe are indicative of our core operating cash flow. A reconciliation of GAAP to non-GAAP operating cash flow is set forth in the table below (in thousands).

	March 31, 2020			March 31, 2019
Operating cash flow	$	(16,497	)	$	42,714
Sinovel settlement (net of legal fees and expenses)		1,000			(52,740	)
Tax effect of Sinovel settlement, net		3,323			2,377
Non-GAAP operating cash flow	$	(12,174	)	$	(7,649	)

Legal Proceedings

From time to time, we are involved in legal and administrative proceedings and claims of various types. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements.

29

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating transactions that are not required to be reflected on our balance sheet except as discussed below.

We occasionally enter into construction contracts that include a performance bond. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is probable, we would record a liability.

In addition, we have various contractual arrangements, under which we have committed to purchase certain minimum quantities of goods or services on an annual basis.

Recent Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU and its amendments were effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

• In July 2018, the FASB issued ASU 2018-10, Codification improvements to Topic 842, Leases. The amendments in ASU 2018-10 provide more clarification in regards to the application and requirements of ASU 2016-02.

• In July 2018, the FASB issued ASU 2018-11, Topic 842, Leases - Targeted improvements. The amendments in ASU 2018-11 provide for the option to adopt the standard prospectively and recognize a cumulative-effect adjustment to the opening balance of retained earnings as well as offer a new practical expedient that will allow us to elect, by class of underlying asset, to not separate non-lease and lease components in certain circumstances and instead to account for those components as a single item.

ASU 2016-02 became effective on April 1, 2019, and we adopted the standard using the modified retrospective transition method, which impacted all leases existing at, or entered into after, the period of adoption. For all leases existing at the time of adoption we recognized a right-of-use asset and lease liability on the balance sheet.  See Note 14 "Leases" for additional information.

30

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year.  Following the release of ASU 2019-10 in November 2019, the new effective date, as long as the Company remains a smaller reporting company, would be annual reporting periods beginning after December 15, 2022.  The Company is currently evaluating the impact, if any, the adoption of ASU 2016-13 may have on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11, Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). The amendments in ASU 2017-11 provide guidance for freestanding equity-linked financial instruments, such as warrants and conversion options in convertible debt or preferred stock, and should no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2017-11 and noted no significant impact on its consolidated financial statements, primarily due to the put option feature within the Company's warrant agreements which required continued liability classification under ASC 480.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in ASU 2017-12 provide improved financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify the application of the hedge accounting guidance. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2017-12 and noted no significant impact on its consolidated financial statements, primarily due to the fact that there are no longer any hedging instruments included in its results.

In June 2018, the FASB issued ASU 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made.  The amendments in ASU 2018-08 assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transactions) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional.  The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods.  As of April 1, 2019, the Company has adopted ASU 2018-08 and noted additional disclosures within its revenue footnote to appropriately present the revenue related to its grant revenue.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods.  As we currently do not report on any level 3 fair value measurements, we are not expecting any material changes to our financial statements with the adoption of ASU 2018-13.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 provide for simplified accounting to several income tax situations and removal of certain accounting exceptions. The ASU is effective for annual reporting periods beginning after December 15, 2020, including interim periods within those periods. We do not expect the impact of the adoption of ASU 2019-12 to be material to our consolidated financial statements.

We do not believe that other recently issued accounting pronouncements will have a material impact on our financial statements.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ under different assumptions or conditions. Our accounting policies that involve the most significant judgments and estimates are as follows:

• Revenue recognition;

• Marketable Securities;

• Accounts receivable;

• Inventory;

• Valuation of long-lived assets;

• Leases;

• Goodwill;

• Income taxes;

• Stock-based compensation;

• Contingencies;

• Product warranty; and

• Fair value of financial instruments.

Revenue recognition

On April 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers using the modified retrospective method.  Revenue contracts are defined as an arrangement that creates enforceable rights and obligations of both parties where collection of the contract price is deemed probable. We record revenue based on a five-step model which includes verifying the existence of the contract, identifying the performance obligations, determining the transaction price, allocating the contract transaction price to the performance obligations, and recognizing the revenue when (or as) control of goods or services is transferred to the customer.   The transfer of control can occur at the time of delivery, installation or post-installation where applicable. 

The Company's equipment and system product line includes certain contracts which do not meet the requirements of an exchange transaction and therefore do not fall within the scope of ASC 606.  As these non-exchange transaction contracts are considered grant revenue and do not fall within any specific accounting literature, the Company follows guidance within ASC 606 by analogy to recognize grant revenue over time. 

For certain arrangements, such as contracts to perform research and development, prototype development contracts and certain customized product sales, we record revenues using the over-time method, measured by the relationship of costs incurred to total estimated contract costs. Over-time revenue recognition accounting is predominantly used on certain turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government. We follow this method when any of the three following criteria are met: when the customer receives the benefits as they are performed, control transfers to the customer as the work is performed, or there is no alternative use to us and there is an enforceable right to payment including a reasonable profit through the life of the contract. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. For contracts where reasonably dependable estimates of the revenues and costs cannot be made, we follow the point in time method.

We enter into sales arrangements that may provide for multiple performance obligations to a customer. Sales of certain products may include extended warranty and support or service packages, and at times include performance bonds. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is likely; we would record a liability. We would reduce revenue to the extent a liability is recorded. In addition, we enter into licensing arrangements that include training services.

Performance obligations are separated into more than one unit of accounting when (1) the delivered element(s) have value to the customer on a stand-alone basis, and (2) our promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract.  In general, revenues are separated between the different product shipments which have stand-alone value, and the various services to be provided. Revenue for product shipments is generally recognized at a point in time where control of the product is transferred to the customer, while revenues for the services are generally recognized over the period of performance. We identify all goods and/or services that are to be delivered separately under a sales arrangement and allocate the transaction price to each distinct performance obligation using the respective standalone selling price ("SSP") which is determined primarily using the cost plus expected margin approach for products and a relief from royalty method for licenses.  Revenue allocated to each performance obligation is recognized when, or as, the performance obligation is satisfied.  We review SSP and the related margins at least annually.

Our license agreements provide either for the payment of contractually determined paid-up front license fees or milestone based payments in consideration for the grant of rights to manufacture and or sell products using our patented technologies or know-how. Some of these agreements provide for the release of the licensee from past and future intellectual property infringement claims. When we can determine that we have no further obligations other than the grant of the license and that we have fully transferred the technology know-how, we recognize the revenue under a point in time model. In other license arrangements, we may also agree to provide training services to transfer the technology know-how.  In these arrangements, we have determined that the licenses have no standalone value to the customer and are not separable from training services as we can only fully transfer the technology know-how through the training component. Accordingly, we account for these arrangements as a single unit of accounting, and recognize revenue over the period of its performance using the over-time method. Costs for these arrangements are expensed as incurred.

Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability of any portion of the contract value is not probable, an analysis of variable consideration will be performed using either the most likely amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability has been resolved. For contractual arrangements that involve variable consideration, we recognize revenue for these amounts upon reaching the constraining event successfully.  We do not generally provide for extended payment terms or provide our customers with a right of return.

Infrequently, we receive requests from customers to hold product being purchased from us for a valid business purpose. We recognize revenues for such arrangements provided the transaction meets, at a minimum, the following criteria: a valid business purpose for the arrangement exists; risk of ownership of the purchased product has been transferred to the buyer; there is a fixed delivery date that is reasonable and consistent with the buyer’s business purpose; the product is ready for shipment; we have no continuing performance obligation in regards to the purchased product and these products have been segregated from our inventories and cannot be used to fill other orders received. There were no such transactions during the fiscal year ended March 31, 2019.  For the fiscal year ended March 31, 2018, such transactions recognized as revenue were $3.7 million.

We have elected to record taxes collected from customers on a net basis and do not include tax amounts in revenue or costs of revenue.

Our contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. Our accounts receivable balance is made up entirely of customer contract related balances. 

See Note 3, “Revenue Recognition,” for further information regarding the Company’s adoption of Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers.

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than 12 months that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. We determine the appropriate classification of marketable securities at the time of purchase and re-evaluate such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net.  We periodically review the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of allowances for doubtful accounts. Our accounts receivable relate principally to a limited number of customers. As of March 31, 2020 Fuji Bridex Pte. Ltd. accounted for approximately 25%, Department of Homeland Security accounted for 18%, and Doosan Heavy Industries & Construction Co., Ltd. accounted for approximately 17% of our accounts receivable balance, with no other customers accounting for greater than 10% of the balance.   As of March 31, 2019, of our total receivable balance, Vestas accounted for approximately 21%, and RES System 3, LLC accounted for approximately 16%, with no other customers accounting for greater than 10% of the balance. Changes in the financial condition or operations of our customers may result in delayed payments or non-payments which would adversely impact our cash flows from operating activities and/or our results of operations. As such, we may require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In determining the allowance for doubtful accounts, we evaluate the collectability of accounts receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due receivables, specific customer circumstances, and current economic trends. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances may be required. Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

33

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value determined on a first-in, first-out basis as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. We record inventory when we take delivery and title to the product according to the terms of each supply contract.

Program costs may be deferred and recorded as inventory on contracts on which costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

At each balance sheet date, we evaluate our ending inventories for excess quantities and obsolescence. Inventories that management considers excess or obsolete are reserved. Management considers forecasted demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases.

We recorded inventory reserves of $1.3 million and $0.9 million during fiscal 2019 and 2018, respectively, based on evaluating our ending inventories for excess quantities and obsolescence.

Valuation of long-lived assets

We periodically evaluate our long-lived assets, consisting principally of fixed and amortizable intangible assets for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived assets, we review the carrying value of our long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of the assets may not be recoverable. Under the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The determination of our asset groups involves a significant amount of judgment, assumptions and estimates.  We evaluate our long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets may not be recoverable from the estimated undiscounted future cash flows.

Our judgments regarding the existence of impairment indicators are based on market and operational performance. Indicators of potential impairment include:

• a significant change in the manner in which an asset group is used;

• a significant decrease in the market value of an asset group;

• identification of other impaired assets within a reporting unit;

• a significant adverse change in its business or the industry in which it is sold;

• a current period operating cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the asset group; and

• significant advances in our technologies that require changes in our manufacturing process.

There were no indicators requiring further impairment testing on our long-lived assets during the fiscal years ended March 31, 2020 or 2019.

34

Leases

Leases include all agreements in which we obtain control of a physical asset.  Leases are captured on the balance sheet as both a right of use asset and associated lease liability and are valued based on the commencement of our control of the asset, after being discounted by our incremental borrowing rate.  Our lease portfolio is made up primarily of real estate leases for our various offices, but also includes items such as vehicles, IT equipment and other miscellaneous tools and equipment needed for manufacturing.  Our incremental borrowing rate was determined through an analysis to identify what rates we could obtain if we were to secure external financing for similar transactions, and includes considerations of both the market and our current credit ratings.  An analysis will be performed annually, or upon execution of any individually material agreement, to ensure that the rates being applied to newly acquired leases are still accurate.

The majority of our leases are classified as operating leases, and therefore the expense is captured in income from operations each period.

We have elected to exclude all leases of less than twelve months from the balance sheet presentation.  We have also elected a policy in which we will not segregate lease components from non-lease components, so in the event we execute an agreement which includes a non-lease component our asset and liability recorded to the balance sheet will include the value of that non-lease component as well.  This policy will be applied to all classifications of leases.

Goodwill

Goodwill represents the excess of cost over net assets of acquired businesses that are consolidated. We perform our annual assessment of goodwill on February 28 of each fiscal year and whenever events or changes in circumstances or a triggering event indicate that the carrying amount may not be recoverable. Determining whether a triggering event has occurred often involves significant judgment from management. An entity is permitted to first assess qualitatively whether it is necessary to perform a goodwill impairment test. The quantitative impairment test is required only if the entity concludes that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. We determine the fair value of a reporting unit based on an income approach utilizing a discounted cash flow adjusted for entity specific factors. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should consider the totality of all relevant events or circumstances that affect the fair value or carrying amount of a reporting unit.  If the carrying value of a reporting unit exceeds the reporting unit’s fair value, then an impairment charge is recognized reducing the goodwill by the excess of the carrying amount over the fair value, not to exceed the total amount of the goodwill, allocated to that reporting unit.  See Note 4, “Acquisition and Related Goodwill” for further information and discussion.

We performed our annual assessment of goodwill on February 28, 2020 and noted no triggering events from the analysis date to March 31, 2020 and determined that there was no impairment to goodwill.  

Income taxes

Our provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse. All deferred tax assets and liabilities are presented as non-current in the Consolidated Balance Sheet.

We regularly assess our ability to realize our deferred tax assets. Assessments of the realization of deferred tax assets require that management consider all available evidence, both positive and negative, and make significant judgments about many factors, including the amount and likelihood of future taxable income. Based on all the available evidence, we have recorded valuation allowances to reduce our deferred tax assets to the amount that is more likely than not to be realizable due to the taxable losses that have been incurred since our inception and uncertainty around our future profitability.

Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. We reevaluate these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. We include interest and penalties related to gross unrecognized tax benefits within the provision for income taxes. See Note 13, “Income Taxes,” of our consolidated financial statements for further information regarding our income tax assumptions and expenses.

Stock-based compensation

We measure compensation cost arising from the grant of share-based payments to employees and non-employees at fair value and recognize such cost over the period during which the employee and non-employee is required to provide service in exchange for the award, usually the vesting period. Total stock-based compensation expense recognized during the fiscal years ended March 31, 2020 and 2019, was $1.9 million and $3.0 million, respectively. For awards with service conditions only, we recognize compensation cost on a straight-line basis over the requisite service/vesting period. For awards with performance conditions, accruals of compensation cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards requires the input of highly subjective assumptions, including the expected life of the share-based payment awards and stock price volatility. Management determined that expected volatility rates should be estimated based on historical and implied volatilities of our common stock. The expected term represents the average time that the options that vest are expected to be outstanding based on the vesting provisions and our historical exercise, cancellation and expiration patterns. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if circumstances change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are required to estimate an 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 stock-based compensation expense could be significantly different from what we have recorded in the current period. See Note 15, “Stockholders’ Equity,” of our consolidated financial statements for further information regarding our stock-based compensation assumptions and expenses.

We account for share-based payments made to non-employees in the same manner as other share-based payments for employees, with the measurement being based on the fair value at the grant date.   The non-employee share based payments will be included within our stock compensation currently reported.

35

Contingencies

From time to time, we are involved in legal and administrative proceedings and claims of various types. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements. If, with respect to a matter, it is not both probable to result in liability and the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss shall be disclosed unless such an estimate cannot be made. We do not recognize gain contingencies until they are realized. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 16, “Commitments and Contingencies”, of our consolidated financial statements for further information.

Product Warranty

Warranty obligations are incurred in connection with the sale of our products. We generally provide a one to three year warranty on our products, commencing upon installation. The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates and related costs to repair given products. The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the estimated warranty liability would be required.

Fair Value of Financial Instruments

Our financial instruments consist principally of cash and cash equivalents, marketable securities, accounts receivable, notes receivable, accounts payable, accrued expenses, and warrants.  The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses due to their short term nature approximate fair value at March 31, 2020 and 2019. The estimated fair values have been determined through information obtained from market sources and management estimates. Marketable securities consist of certificates of deposit with maturities of greater than 12 months that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. We determine the appropriate classification of our marketable securities at the time of purchase and re-evaluate such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.  Changes in fair value are recorded to other income (expense), net.  Notes receivable fair value has been estimated based on a present value calculation using current market information for a similar term loan with similar terms. We have appropriately valued notes receivable within Level 2 of the valuation hierarchy. The fair value for the debt and warrant arrangements were historically estimated by management based on the terms that we believe we could obtain in the current market for debt with the same terms and similar maturities.  The warrants were subject to revaluation at each balance sheet date, and any change in fair value was recorded as a change in fair value in other (expense) income until the earlier of the warrants’ exercise or expiration. We relied on assumptions used in a lattice model to determine the fair value of the warrants. We have appropriately valued the warrants within Level 3 of the valuation hierarchy.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of American Superconductor Corporation

Opinions on the Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of American Superconductor Corporation and subsidiaries (the Company) as of March 31, 2020 and 2019, and the related consolidated statements of operations, comprehensive income (loss), stockholders' equity and cash flows for the years then ended, and the related notes (collectively, the financial statements). We also have audited the Company’s internal control over financial reporting as of March 31, 2020, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2020, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

Basis for Opinions

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. Nature of the Business and Operations and Liquidity

Nature of the Business and Operations

American Superconductor Corporation (together with its subsidiaries, “AMSC®” or the “Company”) was founded on April 9, 1987. The Company is a leading system provider of megawatt-scale power solutions that enhance the performance of the power grid, protect the Navy’s fleet, and lower the cost of wind power. The Company’s products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.

The Company’s consolidated financial statements have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form 10-K. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Liquidity

The Company has historically experienced recurring operating losses and as of March 31, 2020, the Company had an accumulated deficit of $978.6 million. In addition, the Company has historically experienced recurring negative operating cash flows.  At March 31, 2020, the Company had cash, cash equivalents, and marketable securities of $59.9 million. Marketable securities include certificate of deposits with maturities between eleven and eighteen months.  Cash used in operations for the year ended March 31, 2020 was $16.5 million.

On July 3, 2018, the Company and its wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GMBH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settled the litigation and arbitration proceedings between the Company and Sinovel. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018, which was repatriated to the U.S. entity during the nine months ended December 31, 2018, and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018.  The Company's fiscal 2018 results include the net gain received from the settlement with Sinovel of $52.7 million.

On February 1, 2018, ASC Devens LLC (the “Seller”), a wholly-owned subsidiary of the Company, entered into a Purchase and Sale Agreement (the “PSA”) with 64 Jackson, LLC (the “Purchaser”) and Stewart Title Guaranty Company (“Escrow Agent”), to effectuate the sale of certain real property located at 64 Jackson Road, Devens, Massachusetts, including the building that had served as the Company’s headquarters (collectively, the “Property”), in exchange for total consideration of $23.0 million, composed of (i) cash consideration of $17.0 million, and (ii) a $6.0 million subordinated secured commercial promissory note payable to the Company (the “Seller Note”). Subsequently, the Seller, the Purchaser and Jackson 64 MGI, LLC (“Assignee”) entered into an Assignment of Purchase and Sale Agreement (the “Assignment Agreement”), pursuant to which the Purchaser assigned all of its rights and interests in the PSA to the Assignee and the Assignee agreed to assume all of the Purchaser’s obligations and liabilities under the PSA. The transaction closed on March 28, 2018, at which time the Company received, from the Assignee, cash consideration, net of certain agreed upon closing costs, of $16.9 million, and the Seller Note at an interest rate of 1.96%. The Seller Note is secured by a subordinated second mortgage on the Property and a subordinated second assignment of leases and rents.  The Company received the first $3.0 million payment due pursuant to the Seller Note on March 28, 2019 and the second $3.0 million payment plus interest on May 23, 2019.

In December 2015, the Company entered into a set of strategic agreements valued at approximately $210.0 million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems to Inox and a license agreement allowing Inox to manufacture a limited number of electrical control systems. After Inox purchases the specified number of electrical control systems required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its electrical control systems requirements for an additional three-year period.  Pursuant to these strategic agreements, Inox must forecast future purchase orders of sets of Electrical Control Systems ("ECS") which become firm orders three months prior to shipment, and Inox must post letters of credit before the Company will ship such orders. Inox is currently delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On May 29, 2020, the Company sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox fails to post letters of credit in the amount of €6.0 million in accordance with the terms of the supply contract within the ninety day cure period after receipt of the default notice, then the Company may terminate the supply contract by providing written notice of such termination to Inox.  We cannot predict if and when Inox will post letters of credit consistent with the forecasted ECS quantities. Inox’s failure to post letters of credit and take delivery of forecasted ECS quantities would impact the Company’s revenues and liquidity.  In the event the Company were to terminate the supply contract, the Company's revenues and liquidity would also be impacted.

The Company issued warrants in conjunction with an equity offering to Hudson Bay Capital ("Hudson") in November 2014 (the "Hudson Warrant").  The Hudson Warrant was partially exercised on November 13, 2019 with an exercise price of $7.81. The Company received $6.1 million in cash for the exercise of 786,000 warrants. The remaining 32,181 warrants expired unexercised on November 13, 2019.

In March 2020, the World Health Organization declared the disease caused by the novel coronavirus (“COVID-19“) to be a pandemic. COVID-19 has spread throughout the globe, including in the Commonwealth of Massachusetts where the Company’s headquarters are located, and in other areas where the Company has business operations. In response to the outbreak, the Company has followed the guidelines of the U.S. Centers for Disease Control and Prevention (“CDC”) and applicable state government authorities to protect the health and safety of the Company’s employees, families, suppliers, customers and communities. While these existing measures and, COVID-19 generally, have not materially disrupted the Company’s business to date, any future actions necessitated by the COVID-19 pandemic may result in disruption to the Company’s business.

While the COVID-19 pandemic continues to rapidly evolve, the Company continues to assess the impact of the COVID-19 pandemic to best mitigate risk and continue the operations of the Company’s business. The extent to which the outbreak impacts the Company’s business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including new information that may emerge concerning the severity of the COVID-19 pandemic and the actions to contain it or treat its impact, among others.  If the Company, its customers or suppliers experience prolonged shutdowns or other business disruptions, the Company’s business, liquidity, results of operations and financial condition are likely to be materially adversely affected, and the Company’s ability to access the capital markets may be limited. 

43

The Company believes that based on the information presented above and its annual management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next twelve months following the issuance of the financial statements for the year ended March 31, 2020. The Company’s liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary. The impact of the COVID-19 pandemic on the global financing markets may reduce the Company's ability to raise additional capital, if necessary, which could negatively impact the Company's liquidity.  There can be no assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above.

2. Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain reclassifications of prior years’ amounts have been made to conform to the current year presentation. These reclassifications had no effect on net income, cash flows from operating activities or stockholders’ equity.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, goodwill and intangible assets, warranty provisions, stock-based compensation, tax reserves, and deferred tax assets. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and, consequently, actual results may differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by the Company’s management there may be other estimates or assumptions that are reasonable, the Company believes that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements.

Cash Equivalents

Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than 12 months that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net.  The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of allowances for doubtful accounts. The Company’s accounts receivable relate principally to a limited number of customers. As of March 31, 2020 Fuji Bridex Pte. Ltd. accounted for approximately 25%, Department of Homeland Security accounted for 18%, and Doosan Heavy Industries & Construction Co., Ltd. accounted for approximately 17% of the Company's total receivable balance, with no other customer accounting for greater than 10% of the balance.  As of March 31, 2019, Vestas accounted for approximately 21% and RES System 3, LLC accounted for approximately 16% of the Company’s total receivable balance, with no other customer accounting for greater than 10% of the balance.  Changes in the financial condition or operations of the Company’s customers may result in delayed payments or non-payments which would adversely impact its cash flows from operating activities and/or its results of operations. As such, the Company may require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In determining the allowance for doubtful accounts, the Company evaluates the collectability of accounts receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due receivables, specific customer circumstances, and current economic trends. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances may be required. Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on the Company’s business, financial condition, results of operations, and cash flows.

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value determined on a first-in, first-out basis as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company records inventory when it takes delivery and title to the product according to the terms of each supply contract.

Program costs may be deferred and recorded as inventory on contracts on which costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

44

At each balance sheet date, the Company evaluates its ending inventories for excess quantities and obsolescence. Inventories that management considers excess or obsolete are reserved. Management considers forecasted demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases.

For the fiscal years ended March 31, 2020 and 2019, the Company recorded inventory reserves of approximately $1.3 million and $0.9 million, respectively, based on evaluating its ending inventory on hand for excess quantities and obsolescence.

Leases

Leases include all agreements in which we obtain control of a physical asset.  Leases are captured on the balance sheet as both a right of use asset and associated lease liability and are valued based on the commencement of our control of the asset, after being discounted by our incremental borrowing rate.  Our lease portfolio is made up primarily of real estate leases for our various offices, but also include items such as vehicles, IT equipment and other miscellaneous tools and equipment needed for manufacturing.  Our incremental borrowing rate was determined through an analysis to identify what rates we could obtain if we were to secure external financing for similar transactions, and includes considerations of both the market and our current credit ratings.  An analysis is performed annually, or upon execution of any individually material agreement, to ensure that the rates being applied to newly acquired leases are still accurate.

The majority of the Company's leases are classified as operating leases, and therefore the expense is captured in income from operations each period.

We have elected to exclude all leases of less than twelve months from the balance sheet presentation.  We have also elected a policy in which we will not segregate lease components from non-lease components, so in the event we execute an agreement which includes a non-lease component our asset and liability recorded to the balance sheet will include the value of that non-lease component as well.  This policy will be applied to all classifications of leases.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and amortization. The Company accounts for depreciation and amortization using the straight-line method to allocate the cost of property, plant and equipment over their estimated useful lives as follows:

Asset Classification	Estimated Useful Life in Years
Machinery and equipment	3-10
Furniture and fixtures	3-5
Leasehold improvements	Shorter of the estimated useful life or the remaining lease term

Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the costs and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in operating expenses.

Valuation of Long-Lived Assets

The Company periodically evaluates its long-lived assets, consisting principally of fixed assets and amortizable intangible assets, for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived assets, the Company reviews the carrying value of its long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of the assets may not be recoverable. Under the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The Company evaluates its long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets may not be recoverable from the estimated undiscounted future cash flows.

There were no indicators requiring impairment testing on the Company's long-lived assets during the fiscal years ended March 31, 2020 and 2019.

Goodwill

Goodwill represents the excess of cost over net assets of acquired businesses that are consolidated. The Company performs its annual assessment of goodwill on February 28th of each fiscal year and whenever events or changes in circumstances or a triggering event indicate that the carrying amount may not be recoverable. Determining whether a triggering event has occurred often involves significant judgment from management. An entity is permitted to first assess qualitatively whether it is necessary to perform a goodwill impairment test. The quantitative impairment test is required only if the entity concludes that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. The Company determines the fair value of a reporting unit based on an income approach utilizing a discounted cash flow adjusted for entity specific factors. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should consider the totality of all relevant events or circumstances that affect the fair value or carrying amount of a reporting unit.  If the carrying value of a reporting unit exceeds the reporting unit’s fair value, then an impairment charge is recognized reducing the goodwill by the excess of the carrying amount over the fair value, not to exceed the total amount of the goodwill allocated to the that reporting unit. See Note 4, "Acquisition and Related Goodwill" for further information and discussion.

The Company performed its annual assessment of goodwill on February 28, 2020 and noted no triggering events from the analysis date to March 31, 2020 and determined that there was no impairment to goodwill.  Additionally, there was no impairment identified for the fiscal year ended March 31, 2019 based on the assessment performed in the prior fiscal year.

45

Revenue Recognition

Revenue contracts are defined as an arrangement that creates enforceable rights and obligations of both parties where collection of the contract price is deemed probable. The Company records revenue based on a five-step model which includes confirmation of contract existence, identifying the performance obligations, determining the transaction price, allocating the contract transaction price to the performance obligations, and recognizing the revenue when (or as) control of goods or services is transferred to the customer. The transfer of control can occur at the time of delivery, installation or post-installation where applicable. 

The Company's equipment and system product line includes certain contracts which do not meet the requirements of an exchange transaction and therefore do not fall within the scope of ASC 606.  As these non-exchange transaction contracts are considered grant revenue and do not fall within any specific accounting literature, the Company follows guidance within ASC 606 by analogy to recognize grant revenue over time. 

For certain arrangements, such as contracts to perform research and development, prototype development contracts and certain customized product sales, the Company records revenues using the over-time method, measured by the relationship of costs incurred to total estimated contract costs. Over-time revenue recognition accounting is predominantly used on certain turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government. The Company follows this method when any of the three following criteria are met: when the customer receives the benefits as they are performed, control transfers to the customer as the work is performed, or there is no alternative use to the Company and there is an enforceable right to payment through the life of the contract. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. For contracts where reasonably dependable estimates of the revenues and costs cannot be made, the Company follows the point in time method.

The Company enters into sales arrangements that may provide for multiple performance obligations to a customer. Sales of certain products may include extended warranty and support or service packages, and at times include performance bonds. As these contracts progress, the Company continually assesses the probability of a payout from the performance bond. Should the Company determine that such a payout is likely; the Company would record a liability. The Company would reduce revenue to the extent a liability is recorded. In addition, the Company enters into licensing arrangements that include training services.

Performance obligations are separated into more than one unit of accounting when (1) the delivered element(s) have value to the customer on a stand-alone basis, and (2) the Company's promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract.  In general, revenues are separated between the different product shipments which have stand-alone value, and the various services to be provided. Revenue for product shipments is generally recognized at a point in time where control of the product is transferred to the customer, while revenues for the services are generally recognized over the period of performance. The Company identifies all goods and/or services that are to be delivered separately under a sales arrangement and allocates the transaction price to each distinct performance obligation using the respective standalone selling price ("SSP") which is determined primarily using the cost plus expected margin approach for products and a relief from royalty method for licenses.  Revenue allocated to each performance obligation is recognized when, or as, the performance obligation is satisfied.  The Company reviews SSP and the related margins at least annually.

46

The Company’s license agreements provide either for the payment of contractually determined paid-up front license fees or milestone based payments in consideration for the grant of rights to manufacture and or sell products using its patented technologies or know-how. Some of these agreements provide for the release of the licensee from past and future intellectual property infringement claims. When the Company can determine that it has no further obligations other than the grant of the license and that the Company has fully transferred the technology know-how, the Company recognizes the revenue under a point in time model. In other license arrangements, the Company may also agree to provide training services to transfer the technology know-how.  In these arrangements, the Company has determined that the licenses have no standalone value to the customer and are not separable from training services as the Company can only fully transfer the technology know-how through the training component. Accordingly, the Company accounts for these arrangements as a single unit of accounting, and recognizes revenue over the period of its performance using the over-time method. Costs for these arrangements are expensed as incurred.

Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability of any portion of the contract value is not probable, an analysis of variable consideration will be performed using either the most likely amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability has been resolved. For contractual arrangements that involve variable consideration, the Company recognizes revenue for these amounts upon reaching the constraining event successfully.  The Company does not generally provide for extended payment terms or provide its customers with a right of return.

The Company has elected to record taxes collected from customers on a net basis and does not include tax amounts in revenue or costs of revenue.

The Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances. 

See Note 3, “Revenue Recognition,” for further information regarding the Company’s adoption of Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers.

Product Warranty

Warranty obligations are incurred in connection with the sale of the Company’s products.  The Company provides assurance-type warranties on all product sales for a term of typically one to three years, and extended service-type warranties at the customers’ option for an additional term ranging up to four additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the service.  The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates and related costs to repair given products. The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the estimated warranty liability would be required.

Research and Development Costs

Research and development costs are expensed as incurred.

47

Income Taxes

The Company’s provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carry-forwards using expected tax rates in effect in the years during which the differences are expected to reverse.

Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each fiscal year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. The Company has provided a valuation allowance against its U.S. and China deferred income tax assets since the Company believes that it is more likely than not that these deferred tax assets are not currently realizable due to uncertainty around profitability in the future.

Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company includes interest and penalties related to gross unrecognized tax benefits within the provision for income taxes.  See Note 13, “Income Taxes,” for further information regarding its income tax assumptions and expenses.

Stock-Based Compensation

The Company accounts for stock-based payment transactions using a fair value-based method and recognizes the related expense in the results of operations.

Stock-based compensation is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period of the award. The fair value of restricted stock awards is determined by reference to the fair market value of the Company’s common stock on the date of grant. The Company uses the Black-Scholes option pricing model to estimate the fair value of awards with service and performance conditions. For awards with service conditions only, the Company recognizes compensation cost on a straight-line basis over the requisite service/vesting period. For awards with performance conditions, accruals of compensation cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatilities of the Company’s common stock and expected terms. The expected volatility rates are estimated based on historical and implied volatilities of the Company’s common stock. The expected term represents the average time that the options that vest are expected to be outstanding based on the vesting provisions and the Company’s historical exercise, cancellation and expiration patterns.

The Company estimates pre-vesting forfeitures when recognizing compensation expense based on historical and forward-looking factors. Changes in estimated forfeiture rates and differences between estimated forfeiture rates and actual experience may result in significant, unanticipated increases or decreases in stock-based compensation expense from period to period. The termination of employment of certain employees who hold large numbers of stock-based awards may also have a significant, unanticipated impact on forfeiture experience and, therefore, on stock-based compensation expense. The Company will update these assumptions on at least an annual basis and on an interim basis if significant changes to the assumptions are warranted.

The Company accounts for share-based payments made to non-employees in the same manner as other share-based payments for employees, with the measurement being based on the fair value at the grant date.   The non-employee share based payments will be included within the Company's stock compensation currently reported.

Computation of Net Income (Loss) per Common Share

Basic net income (loss) per share (“EPS”) is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing the net loss by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. For the fiscal years ended March 31, 2020 and 2019, common equivalent shares of 354,748, and 907,988, respectively, were not included in the calculation of diluted EPS as they were considered antidilutive. The following table reconciles the numerators and denominators of the EPS calculation for the fiscal years ended March 31, 2020 and 2019 (in thousands except per share amounts):

Foreign Currency Translation

The functional currency of all the Company’s foreign subsidiaries is the U.S. dollar, except for AMSC Austria, for which the local currency (Euro) is the functional currency, and AMSC China, for which the local currency (Renminbi) is the functional currency. The assets and liabilities of AMSC Austria and AMSC China are translated into U.S. dollars at the exchange rate in effect at the balance sheet date and income and expense items are translated at average rates for the period. Cumulative translation adjustments are excluded from net loss (income) and shown as a separate component of stockholders’ equity. Net foreign currency gains and losses are included in other income (expense), net on the consolidated statements of operations and were $0.1 million and $1.6 million, for the fiscal years ended March 31, 2020 and 2019, respectively. The Company has no restrictions on the foreign exchange activities of its foreign subsidiaries, including the payment of dividends and other distributions.

Risks and Uncertainties

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates and would impact future results of operations and cash flows.

The Company invests its available cash in high credit, quality financial instruments and invests primarily in investment-grade marketable securities, including, but not limited to, government obligations, money market funds and corporate debt instruments.

Several of the Company’s government contracts are being funded incrementally, and as such, are subject to the future authorization, appropriation, and availability of government funding. The Company has a history of successfully obtaining financing under incrementally-funded contracts with the U.S. government and it expects to continue to obtain additional contract modifications in the year ending March 31, 2021 and beyond as incremental funding is authorized and appropriated by the government.

Contingencies

From time to time, the Company may be involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. Management reviews these estimates in each accounting period as additional information is known and adjusts the loss provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in the consolidated financial statements. If, with respect to a matter, it is not both probable to result in liability and the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss is disclosed unless such an estimate cannot be made. The Company does not recognize gain contingencies until they are realized. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 16, “Commitments and Contingencies,” for further information.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments consist principally of cash and cash equivalents, accounts receivable, marketable securities, accounts payable, accrued expenses, warrants to purchase shares of common stock, and derivatives. The carrying amounts of cash and cash equivalents, accounts receivable, short-term debt, accounts payable, and accrued expenses due to their short nature approximate fair value at March 31, 2020 and 2019. The estimated fair values have been determined through information obtained from market sources and management estimates.  Marketable securities consist of certificates of deposit with maturities of greater than 12 months that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net. The fair value for the warrant arrangements was historically estimated by management based on various assumptions in a lattice model and was subject to revaluation at each balance sheet date.  The Company classifies the estimates used to fair value these instruments as Level 3 inputs. See Note 5, “Fair Value Measurements” for a full discussion on fair value measurements.

3. Revenue Recognition

The Company’s revenues in its Grid segment are derived primarily through enabling the transmission and distribution of power, providing planning services that allow it to identify power grid needs and risks, and developing ship protection systems for the U.S. Navy. The Company’s revenues in its Wind segment are derived primarily through supplying advanced power electronics and control systems, licensing its highly engineered wind turbine designs, and providing extensive customer support services to wind turbine manufacturers. The Company records revenue based on a five-step model in accordance with ASC 606. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. As of March 31, 2020, 72% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.

In the Company's equipment and system product line, each contract with a customer summarizes each product sold to a customer, which typically represents distinct performance obligations. A contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales transfer control to the customer in line with the contracted delivery terms and revenue is recorded at the point in time when title and risk transfer to the customer, as the Company has determined that this is the point in time that control transfers to the customer.

The Company's equipment and system product line includes certain contracts which do not meet the requirements of an exchange transaction and therefore do not fall within the scope of ASC 606.  As these non-exchange transaction contracts are considered grant revenue and do not fall within any specific accounting literature, the Company follows guidance within ASC 606 by analogy to recognize grant revenue over time.  In the year ended March 31, 2020, the Company recorded $6.4 million in grant revenue, which is included in the Company’s Grid revenue. There was no grant revenue in the year ended March 31, 2019.

50

In the Company's service and technology development product line, there are several different types of transactions and each begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. The technology development transactions are primarily for activities that have no alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are not deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is not assured and a contract does not exist under ASC 606, revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are no further remaining performance obligations.

The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer which occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided the revenue is recognized over time ratably.

The Company’s policy is to not accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.

The Company provides assurance-type warranties on all product sales for a term of typically one to three years, and extended service-type warranties at the customers’ option for an additional term ranging up to four additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the services.

The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized. The Company has elected to recognize incremental costs of obtaining a contract as expense when incurred except in contracts where the amortization period would exceed twelve months; in such cases the long term amount will be assessed for materiality. The Company has elected to not adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is twelve months or less. 

The Company’s contracts with customers do not typically include extended payment terms and may include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from delivery.

The following tables disaggregate the Company’s revenue by product line and by shipment destination:

In the fiscal years ended March 31, 2020 and 2019, 51% and 74% of the Company’s revenues, respectively, were recognized from sales outside the United States. The Company maintains operations in Austria, Romania, and the United States and sales and service support centers around the world.

As of March 31, 2020 and March 31, 2019, the Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances. Changes in the Company’s contract assets, which are included in “Unbilled Accounts Receivable” and “Deferred program costs” (see Note 6, “Accounts Receivable” and Note 7, “Inventory” for a reconciliation to the condensed consolidated balance sheet) and contract liabilities, which are included in the current portion and long term portion of “deferred revenue” in the Company’s condensed consolidated balance sheets, are as follows:

	Unbilled AR			Deferred Program Costs			Contract Liabilities
Beginning balance as of March 31, 2019	$	2,213		$	318		$	15,521
Increases for costs incurred to fulfill performance obligations		—			4,844			—
Increase (decrease) due to customer billings		(11,516	)		—			47,877
Decrease due to cost recognition on completed performance obligations		—			(3,525	)		—
Increase (decrease) due to recognition of revenue based on transfer of control of performance obligations		15,017			—			(37,009	)
Other changes and FX impact		(3	)		(6	)		(247	)
Ending balance as of March 31, 2020	$	5,711		$	1,631		$	26,142
	Unbilled AR			Deferred Program Costs			Contract Liabilities
Beginning balance as of March 31, 2018	$	3,016		$	2,567		$	21,937
Impact of adoption of ASC 606		—			(1,599	)		(2,657	)
Increases for costs incurred to fulfill performance obligations		—			1,585			—
Increase (decrease) due to customer billings		(12,076	)		—			20,540
Decrease due to cost recognition on completed performance obligations		—			(2,212	)		—
Increase (decrease) due to recognition of revenue based on transfer of control of performance obligations		11,324			(9	)		(23,084	)
Other changes and FX impact		(51	)		(14	)		(1,215	)
Ending balance as of March 31, 2019	$	2,213		$	318		$	15,521

The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations may vary significantly each reporting period based on the timing of major new contractual commitments. As of March 31, 2020, the Company had outstanding performance obligations on existing contracts under ASC 606 to be recognized in the next twelve months of approximately $61.4 million. There are also approximately $8.2 million of outstanding performance obligations to be recognized over a period of thirteen to sixty months. The remaining performance obligations are subject to customer actions and therefore the timing of revenue recognition cannot be reasonably estimated. The twelve month performance obligations include anticipated shipments to Inox based on the twelve month rolling forecast provided by Inox on the multi-year supply contract. The quantities specified in any forecast provided by Inox related to the multi-year supply contract are firm and irrevocable for the first three months of a twelve month rolling forecast. The timing of the performance obligations beyond the Inox-provided twelve month forecast are not determinable and therefore are not included in the total remaining performance obligations.  See Note 1, “Nature of the Business and Operations and Liquidity,” for further information regarding the uncertainty of timing of the performance obligations as a result of the written notice that the Company sent to Inox on May 29, 2020 notifying Inox of its default under the supply contract.

The following table sets forth customers who represented 10% or more of the Company’s total revenues for the year ended March 31, 2020 and 2019:

		Year Ended
	Reportable	March 31,
	Segment	2020	2019
Department of Homeland Security	Grid	10%	<10%
Vestas	Grid	<10%	15%
Inox Wind Limited	Wind	<10%	34%

4. Goodwill

The Company performed its annual assessment of goodwill on February 28, 2020 and noted no triggering events from the analysis date to March 31, 2020 and determined that there was no impairment to goodwill.  Additionally, no impairment resulted from the assessment performed in the fiscal year ended March 31, 2019.

5. Fair Value Measurements

A valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1	-	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2	-	Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level 3	-	Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

The Company provides a gross presentation of activity within Level 3 measurement roll-forward and details of transfers in and out of Level 1 and 2 measurements.  A change in the hierarchy of an investment from its current level is reflected in the period during which the pricing methodology of such investment changes.  Disclosure of the transfer of securities from Level 1 to Level 2 or Level 3 is made in the event that the related security is significant to total cash and investments.  The Company did not have any transfers of assets and liabilities from Level 1, Level 2 or Level 3 of the fair value measurement hierarchy during the year ended March 31, 2020.

A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Valuation Techniques

Cash Equivalents

Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than 12 months that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value would be recorded to other income (expense), net.  The Company recognized $0.1 million in unrealized gains on marketable securities, which is recorded in other income, for the fiscal year ending March 31, 2020 and did not recognize any gains or losses on marketable securities in the fiscal year ended March 31, 2019.  The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Warrants

The Company issued warrants in conjunction with an equity offering to Hudson Bay Capital in November 2014 and a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules”). The warrants issued to Hercules were exercised on April 8, 2019.  The warrants issued to Hudson were partially exercised on November 13, 2019 and the remaining unexercised warrants expired on November 13, 2019.  As of March 31, 2020 the Company has no remaining outstanding warrants.

The Company historically relied on various assumptions in a lattice model to determine the fair value of warrants. The Company had valued the warrants within Level 3 of the valuation hierarchy. See Note 12, “Warrants and Derivative Liabilities,” for a discussion of the warrants and the valuation assumptions used.

The following table provides the assets and liabilities carried at fair value on a recurring basis, measured as of March 31, 2020 and 2019 (in thousands):

	Total Carrying Value		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

The Company recorded inventory write-downs of $1.3 million and $0.9 million for the fiscal years ended March 31, 2020 and 2019, respectively.  These write downs were based on evaluating its inventory on hand for excess quantities and obsolescence.

Deferred program costs as of March 31, 2020 and March 31, 2019 primarily represent costs incurred on programs accounted for upon completion of the project when control has transferred to the customer before revenue and costs will be recognized.

8. Note Receivable

AMSC entered into a purchase and sale agreement dated February 1, 2018 for the Devens facility (including land, building and building improvements) located at 64 Jackson Road, Devens, Massachusetts to 64 Jackson Road, LLC, a limited liability company, in the amount of $23.0 million. The terms for payment included a $1.0 million security deposit, and a note receivable for $6.0 million payable to AMSC with the remaining cash net of certain adjustments for closing costs at the date of settlement.

The note receivable was due in two $3.0 million installments plus accrued interest at 1.96% rate.  The first installment was paid on March 28, 2019 and the second installment was paid May 23, 2019. The note was subordinate to East Boston Savings Bank's mortgage on the Devens property. The note receivable was discounted to its present value of $5.7 million utilizing a discount rate of 6%, which was based on management’s assessment of what an appropriate loan at current market rate would be. The $0.3 million discount was recorded as an offset to the long term portion of the note receivable.  As of March 31, 2019, the remaining $0.1 million discount was being amortized to interest income as an offset to the short-term portion of the note, over the remaining term of the note.

In addition, the resulting gain of $0.1 million from the sale of the Devens property which was deferred previously was recorded as a component of the cumulative effect of an accounting change upon the adoption of ASU 2017-05 which was issued as a part of ASU 2014-09. This gain was recorded as an offset to the opening accumulated deficit as of April 1, 2018.

12. Warrants and Derivative Liabilities

The Company accounts for its warrants as liabilities due to certain adjustment provisions within the instruments, which require that they be recorded at fair value. The warrants are subject to revaluation at each balance sheet date and any change in fair value is recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note 5, “Fair Value Measurements” for further discussion.

Hercules Warrant

The Company issued Hercules warrants to purchase 13,927 shares of common stock (the “First Warrant”) and 25,641 shares of common stock (the “Second Warrant”) in conjunction with prior term loans that have been repaid in full. On December 19, 2014, the Company entered into a second amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued Hercules a warrant to purchase 58,823 shares of the Company’s common stock (the "Hercules Warrant") which replaced the First Warrant and the Second Warrant.  The Hercules Warrant was exercisable at any time after its issuance at an exercise price of $7.85 per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in May 2017, the acquisition of Infinia Technology Corporation ("ITC") with common stock in September 2017 and sales of common stock under the ATM entered into in January 2017.  This warrant had a fair value of $0.4 million as of March 31, 2019 and $0.1 million as of March 31, 2018.  On April 8, 2019 Hercules notified the Company of its intent to exercise this warrant on a cashless basis.  Hercules received 22,821 shares of the Company's common stock on April 17, 2019.  As a result of this exercise the Company recorded a net gain of $0.1 million to change in fair value of warrants, resulting from the decrease in the fair value of the Hercules Warrant during the year ended March 31, 2020.  The Company recorded a net loss of $0.2 million to change in fair value of warrants, resulting from the increase in the fair value of the Hercules Warrant during the year ended March 31, 2019.

On November 13, 2014, the Company completed an offering of 909,090 units of the Company’s common stock with Hudson Bay Capital. Each unit consisted of one share of the Company’s common stock and 0.9 of a warrant to purchase one share of common stock, or a warrant to purchase in the aggregate 818,181 shares (the “November 2014 Warrant”).  The November 2014 Warrant was exercisable at any time, at an exercise price equal to $7.81 per share, subject to certain price-based and other anti-dilution adjustments including those noted above.  On November 13, 2019, Hudson partially exercised the November 2014 Warrant for 786,000 restricted shares of Company common stock at $7.81 per share.  The remaining 32,181 warrants expired unexercised on November 13, 2019. As a result of this exercise the Company recorded a net gain $4.6 million to change in fair value of warrants, resulting from the decrease in the fair value of the November 2014 Warrant during the year ended March 31, 2020, and a net loss, resulting from an increase in the fair value of the November 2014 Warrant, of $3.5 million to change in fair value of derivatives and warrants in the fiscal year ended March 31, 2019. As of March 31, 2020, the Company has no remaining outstanding warrants

             On March 27, 2020, the United States enacted the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The Cares Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effect of COVID-19. While the CARES Act provides sweeping tax changes in response to the COVID-19 pandemic, some of the more significant provisions include removal of certain limitations on utilization of net operating losses, increasing the loss carryback period for certain losses to five years, and increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act of 2017. The CARES Act is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

The Company has provided a full valuation allowance against its net deferred income tax assets in the U.S. and China since it is more likely than not that its deferred tax assets will not be realizable. After consideration of all the available evidence, both positive and negative, the Company has determined that a $200.0 million valuation allowance at March 31, 2020 is necessary to reduce the deferred tax assets to the amount that will more likely than not be realized.

At March 31, 2020, the Company had aggregate net operating loss carryforwards in the U.S. for federal and state income tax purposes of approximately $799.2 million and $203.6 million, respectively, which expire in the years ending March 31, 2020 through 2040. For U.S. federal tax purpose, approximately $54.0 million of Federal net operating losses have an indefinite carryforward period. Included in the U.S. net operating loss are $3.7 million of acquired losses from Power Quality Systems, Inc. and $0.3 million of acquired losses from Infinia Technology Corporation. Research and development and other tax credit carryforwards amounting to approximately $10.1 million and $3.5 million are available to offset federal and state income taxes, respectively, and will expire in the years ending March 31, 2020 through 2040.

At March 31, 2020, the Company had aggregate net operating loss carryforwards for its Chinese operation of approximately $56.0 million, which can be carried forward for five years and begin to expire December 31, 2020. 

Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the “IRC”), provides limits on the extent to which a corporation that has undergone an ownership change (as defined) can utilize any net operating loss ("NOL") and general business tax credit carryforwards it may have. The Company last updated its study for the acquisition of ITC.  The Company increased its NOL’s by $0.3 million due to acquired losses in the fiscal year ended March 31, 2018 from ITC. The Company conducted a study on the acquired NOL and concluded that the limitations under Section 382 will not have a material impact on its ability to utilize its NOL carryforwards.  If there were material ownership changes subsequent to the study, such changes could limit the Company's ability to utilize its NOL carryforwards.

The total amount of undistributed foreign earnings available to be repatriated at March 31, 2020 was $1.9 million resulting in the recording of a $0.2 million deferred tax liability for foreign withholding taxes.

The Company has not recorded a deferred tax asset for the temporary difference associated with the excess of the tax greater than the book basis in its Chinese subsidiary as the future tax benefit is not expected to reverse in the foreseeable future.

Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision.  The Company did not identify any uncertain tax positions at March 31, 2020.  The Company did not have any gross unrecognized tax benefits at March 31, 2020 or 2019.

There were no reversals of uncertain tax positions in the fiscal years ended March 31, 2020 and 2019.

The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. Any unrecognized tax benefits, if recognized, would favorably affect its effective tax rate in any future period. The Company does not expect that the amounts of unrecognized benefits will change significantly within the next twelve months.

The Company conducts business globally and, as a result, its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. Major tax jurisdictions include the U.S., China, Romania and Austria. All U.S. income tax filings for fiscal years ended March 31, 1996 through 2020 remain open and subject to examination.

All fiscal years from the fiscal year ended March 31, 2018 through 2020 remain open and subject to examination in Austria.  As of March 31, 2020, the Company remains open to audit for the calendar years 2015 and forward in China.  Tax filings in Romania for the fiscal years ended March 31, 2016 through 2020 remain open and subject to examination.

14. Leases

On April 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842) ("ASC 842"), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did not reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company did not elect the hindsight practical expedient and evaluated lease terms for existing leases. The Company has also elected the practical expedient to not separate lease components and non-lease components and will account for the leases as a single lease component for all classes of leases.

As a result of the adoption of ASC 842, the Company recognized lease right-of-use assets of $3.8 million, and operating lease liabilities of $3.8 million. There was no impact to the condensed consolidated statements of operations or stockholders' equity for the adoption of ASC 842. No impairment was recognized on the right-of-use asset upon adoption. These adjustments are detailed as follows:

	March 31, 2019		ASC 842 Adjustment		April 1, 2019
Operating Leases:
Right of use asset	$	—	$	3,795	$	3,795
Total operating lease right-of-use asset		—		3,795		3,795
Operating lease liabilities – ST	$	—	$	309	$	309
Operating lease liabilities – LT		—		3,512		3,512
Total operating lease liabilities		—		3,821		3,821
Weighted-average remaining lease term					7.69 years
Weighted-average discount rate						7.06	%

All significant lease arrangements are recognized at lease commencement.  Operating lease right–of-use assets and lease liabilities are recognized at commencement. The operating lease right-of-use asset includes any lease payments related to initial direct cost and prepayments and excludes any lease incentives. Lease expense is recognized on a straight-line basis over the lease term.  The Company enters into a variety of operating lease agreements through the normal course of its business, but primarily real estate leases to support its operations. The agreements generally provide for fixed minimum rental payments and the payment of real estate taxes and insurance. Many of these leases have one or more renewal options that allow the Company, at its discretion, to renew the lease for varying periods up to five years or to terminate the lease. Only renewal options or termination rights that the Company believed were likely to be exercised were included in the lease calculations.

The Company also enters into leases for vehicles, IT equipment and service agreements, and other leases related to its manufacturing operations that are also included in the right-of-use asset and lease liability accounts if they are for a term of longer than twelve months. However, many of these leases are either short-term in nature or immaterial. The Company has made the policy election to exclude short-term leases from the balance sheet. 

The discount rate was calculated using an incremental borrowing rate based on an assessment prepared by the Company through the use of Company credit ratings, consideration of its lease populations potential risk to its total capital structure, and a market rate for a collateralized loan for its risk profile, calculated by a third party. The Company elected to apply the discount rate using the remaining lease term at the date of adoption.

The Company did not identify any leases that are classified as financing leases.

Supplemental balance sheet information related to leases at March 31, 2020 are as follows:

	March 31, 2020
Operating Leases:
Right-of-use assets	$	3,359
Total right-of-use assets		3,359

15. Stockholders’ Equity

Stock-Based Compensation Plans

As of March 31, 2020, the Company had two active stock plans: the 2007 Stock Incentive Plan, as amended (the “2007 Plan”) and the Amended and Restated 2007 Director Stock Plan (the “2007 Director Plan”).  On August 1, 2019, the Company’s stockholders approved amendments to the 2007 Plan and the 2007 Director Plan. The amendment to the 2007 Plan increased the total number of shares of common stock authorized for issuance under the 2007 Plan from 3,400,000 shares to 4,600,000 shares. The amendment to the 2007 Director Plan increased the total number of shares of common stock authorized for issuance under the 2007 Director Plan from 230,000 shares to 280,000 shares.

The 2007 Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the IRC of 1986, as amended, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards. In the case of options, the exercise price is no less than the fair market value of the common stock, as determined by (or in a manner approved by) the Board of Directors, on the date of grant. The contractual life of options is generally 10 years. Options generally vest over a 3-5 year period while restricted stock generally vests over a 3 year period.

The 2007 Director Plan provides for the grant of nonstatutory stock options and stock awards to members of the Board of Directors who are not also employees of the Company ("outside directors"). Under the terms of the 2007 Director Plan, each outside director is granted an option to purchase shares of common stock with an aggregate grant date value equal to $40,000 upon his or her initial election to the Board with an exercise price equal to the fair market value of the Company’s common stock on the date of the grant. These options vest in equal annual installments over a two-year period. In addition, each outside director is granted an award of shares of common stock with an aggregate grant date value equal to $40,000 as of the closing price three business days following the last day of each fiscal year, subject to proration for any partial fiscal year of service.

As of March 31, 2020, the 2007 Plan had 1,249,930 shares available for future issuance and the 2007 Director Plan had 108,474 shares available for future issuance.

Stock-Based Compensation

The components of stock-based compensation for the years ended March 31, 2020 and 2019 were as follows (in thousands):

Restricted stock and stock awards		1,870		2,781
Employee stock purchase plan		36		28
Total stock-based compensation expense	$	1,922	$	3,030

The estimated fair value of the Company’s stock-based awards, less expected annual forfeitures, is amortized over the awards’ service period. The total unrecognized compensation cost for unvested outstanding stock options was $0.1 million for the fiscal year ended March 31, 2020. This expense will be recognized over a weighted-average expense period of approximately 1.2 years.  The total unrecognized compensation cost for unvested outstanding restricted stock was $3.4 million for the fiscal year ended March 31, 2020. This expense will be recognized over a weighted-average expense period of approximately 1.6 years.

The following table summarizes stock-based compensation expense by financial statement line item for the fiscal years ended March 31, 2020 and 2019 (in thousands):

There were 94,500 performance-based restricted shares awarded during the fiscal year ended March 31, 2020 for which the performance conditions are deemed probable to be met and the expense is being recorded over the expected vesting period.  There were 57,000 performance-based restricted shares awarded during the fiscal year ended March 31, 2019 of which 28,500 vested and the remaining 28,500 expired during fiscal 2019.

The remaining shares awarded vest upon the passage of time. For awards that vest upon the passage of time, expense is being recorded over the vesting period.

Employee Stock Purchase Plan

The Company maintains the 2000 Employee Stock Purchase Plan, as amended (the "ESPP") which provides employees with the opportunity to purchase shares of common stock at a price equal to the market value of the common stock at the end of the offering period, less a 15% purchase discount. As of March 31, 2020, the ESPP had 203,134 shares available for future issuance. The Company recognized less than $0.1 million of compensation expense for both the fiscal year ended March 31, 2020 and 2019, related to the ESPP.

16. Commitments and Contingencies

Purchase Commitments

The Company periodically enters into non-cancelable purchase contracts in order to ensure the availability of materials to support production of its products. Purchase commitments represent enforceable and legally binding agreements with suppliers to purchase goods or services. The Company periodically assesses the need to provide for impairment on these purchase contracts and record a loss on purchase commitments when required.

Lease Commitments

During the year ended March 31, 2020 all leases were recorded in Lease expense.  See Note 14, "Leases" for further details.  For the year ended March 31, 2019 rent expense was $1.3 million.  See Item 2, “Properties” for further information.

Legal Contingencies

From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

Other

The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all the face amount of the performance bonds into an escrow account until the termination of the bond. When the performance conditions are met, amounts deposited as collateral for the performance bonds are returned to the Company. In addition, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

As of March 31, 2020, the Company had $5.7 million of restricted cash included in long-term assets and $0.5 million of restricted cash in current assets. These amounts included in restricted cash primarily represent deposits to secure letters of credit for various supply contracts including the irrevocable letter of credit in the amount of $5.0 million to secure certain of the Company’s obligations under the Subcontract Agreement with Commonwealth Edison Company. These deposits are held in interest bearing accounts.

65

17. Employee Benefit Plans

The Company has implemented a defined contribution plan (the “Plan”) under Section 401(k) of the IRC. Any contributions made by the Company to the Plan are discretionary. The Company has a stock match program under which the Company matched, in the form of Company common stock, 50% of the first 6% of eligible contributions. The Company recorded expense of $0.3 million for the fiscal year ended March 31, 2020, and $0.3 million for the fiscal year ended March 31, 2019, and recorded corresponding charges to additional paid-in capital related to this program.

18. Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation—Nonretirement Postemployment Benefits (“ASC 712”). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.

The $0.5 million charged to operations in the fiscal year ended March 31, 2019 was related to exit costs incurred primarily during the first half of fiscal 2018 for the move of the Company's corporate office.

The following table presents restructuring charges and cash payments during the year ended March 31, 2019 (in thousands):

	Severance pay and benefits			Facility exit and Relocation costs			Total
Accrued restructuring balance at April 1, 2018	$	262		$	173		$	435
Charges to operations		—			450			450
Cash payments		(262	)		(623	)		(885	)
Accrued restructuring balance at March 31, 2019	$	—		$	—		$	—

All restructuring charges discussed above are included within restructuring in the Company’s consolidated statements of operations. The Company includes accrued restructuring within accounts payable and accrued expenses in the consolidated balance sheets.  There was no restructuring activity in the year ended March 31, 2020 or any remaining accrued restructuring balance as of March 31, 2020 or 2019.

19. Business Segments

The Company reports its financial results in two reportable business segments: Grid and Wind.

Through the Company’s power grid offerings, the Grid business segment enables electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through its transmission planning services, power electronics, and superconductor-based systems. The sales process is enabled by transmission planning services that allow it to identify power grid congestion, poor power quality and other risks, which helps the Company determine how its solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems.  The Company also sells ship protection products to the U.S. Navy through its Grid business segment.

Through the Company’s wind power offerings, the Wind business segment enables manufacturers to field highly competitive wind turbines through its advanced power electronics and control system products, engineered designs, and support services. The Company supplies advanced power electronics and control systems, licenses its highly engineered wind turbine designs, and provides extensive customer support services to wind turbine manufacturers. The Company’s design portfolio includes a broad range of drive trains and power ratings of 2 megawatts ("MWs") and higher. The Company provides a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

The accounting policies of the business segments are the same as those for the consolidated Company. The Company’s business segments have been determined in accordance with the Company’s internal management structure, which is organized based on operating activities. The Company evaluates performance based upon several factors, of which the primary financial measures are segment revenues and segment operating income (loss). The disaggregated financial results of the segments reflect allocation of certain functional expense categories consistent with the basis and manner in which Company management internally disaggregates financial information for the purpose of assisting in making internal operating decisions. In addition, certain corporate expenses which the Company does not believe are specifically attributable or allocable to either of the two business segments have been excluded from the segment operating income (loss).

67

Unallocated corporate expenses primarily consist of stock-based compensation expense of $1.9 million and $3.0 million, in the fiscal years ended March 31, 2020 and 2019, respectively, and restructuring charges of $0.5 million for the fiscal year ended March 31, 2019.

20. Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year.  Following the release of ASU 2019-10 in November 2019, the new effective date, as long as the Company remains a smaller reporting company, would be annual reporting periods beginning after December 15, 2022.   The Company is currently evaluating the impact, if any, the adoption of ASU 2016-13 may have on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11, Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). The amendments in ASU 2017-11 provide guidance for freestanding equity-linked financial instruments, such as warrants and conversion options in convertible debt or preferred stock, and should no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods.  As of April 1, 2019, the Company has adopted ASU 2017-11 and noted no significant impact on its consolidated financial statements, primarily due to the put option feature which required continued liability classification under ASC 840.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in ASU 2017-12 provide improved financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify the application of the hedge accounting guidance. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods.  As of April 1, 2019, the Company has adopted ASU 2017-12 and noted no significant impact on its consolidated financial statements, primarily due to the fact that there are no longer any hedging instruments included in its results.

In June 2018, the FASB issued ASU 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made.  The amendments in ASU 2018-08 assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transactions) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional.  The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2018-08 and noted additional disclosures within its revenue footnote to appropriately present the revenue related to its grant revenue.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods.  As the Company currently does not report on any level 3 fair value measurements, it is not expecting any material changes to its financial statements with the adoption of ASU2018-13.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 provide for simplified accounting to several income tax situations and removal of certain accounting exceptions. The ASU is effective for annual reporting periods beginning after December 15, 2020, including interim periods within those periods. The Company does not expect the impact of the adoption of ASU 2019-12 to be material to its consolidated financial statements.

21. Subsequent Events

The Company has performed an evaluation of subsequent events through the time of filing this Annual Report on Form 10-K with the SEC, and has determined that other than the notice of default discussed in Note 1, there are no such events to report.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE 

None.

Item 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2020. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company 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. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2020, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a–15(f) and 15d–15(f) under the Exchange Act as a process designed by, or under the supervision of, a company’s chief executive officer and chief financial officer, and effected by the board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:

(1) Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of assets;

(2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, an evaluation was conducted of the effectiveness of our internal control over financial reporting based on the Committee of Sponsoring Organizations of the Treadway Commission’s Internal Control – Integrated Framework (2013 Edition). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of March 31, 2020.

The effectiveness of our internal control over financial reporting as of March 31, 2020 has been audited by RSM US LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended March 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. OTHER INFORMATION

The Company and Inox are parties to a supply contract, dated December 16, 2015 (as amended, the “Supply Contract”).  Pursuant to the terms of the Supply Contract, the Company has agreed to supply, and Inox has agreed to purchase, electric control systems (“ECS”) for use in Inox’s 2 megawatt doubly fed wind turbines. Under the Supply Contract, Inox must forecast future purchase orders of sets of ECS which become firm orders three months prior to shipment, and post irrevocable documentary letters of credit (“Approved L/Cs”) before the Company will ship such orders. Inox is currently delinquent on its obligation to post Approved L/Cs for sets of ECS that Inox forecasted to purchase under the terms of the Supply Contract.

On May 29, 2020, pursuant to Section 19.1 of the Supply Contract, the Company sent written notice (the “Default Notice”) to Inox notifying Inox of its default under Sections 3.4 and 3.5 of the Supply Contract due to Inox’s failure to post and maintain Approved L/Cs in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the Supply Contract.  

If Inox fails to post and maintain Approved L/Cs in the amount of €6.0 million in accordance with the terms of the Supply Contract within the 90 (ninety) day cure period after receipt of the Default Notice, then the Company may terminate the Supply Contract by providing written notice of such termination to Inox. 

The foregoing description of the Supply Contract is not complete and is qualified in its entirety by reference to the full text of the Supply Contract, a copy of which was filed as Exhibit 10.1 to the Company’s Quarterly Report on Form 10-Q for the quarter ended December 31, 2015, filed with the United States Securities and Exchange (“SEC”) on February 9, 2016, as amended by Amendment No. 1 and Amendment No. 2, filed as Exhibits 10.29 and 10.30, respectively, to the Company’s Annual Report on Form 10-K for the year ended March 31, 2018, filed with the SEC on June 6, 2018. The Supply Contract, as amended, is incorporated herein by reference.

Attention: James Maguire, EVP Technology

Re: HSBC Bank USA, N.A. Standby Letter of Credit dated August 6, 2019

Ladies and Gentlemen:

Reference is made to (i) that certain Subcontract Agreement No. 08900001-007 (the “Agreement”), dated October 31, 2018, by and between American Superconductor Corporation (“AMSC”) and Commonwealth Edison (“Subcontractor”), and (ii) that certain Standby Letter of Credit issued by HSBC Bank USA, N.A. (“HSBC”) on August 6, 2019 (the “Original Letter of Credit”). Notwithstanding anything in the Agreement to the contrary, AMSC and Subcontractor hereby agree as follows:

1. AMSC has provided to Subcontractor as of the date hereof an amendment to the Original Letter of Credit, a copy of which is attached hereto as Exhibit A (the “Letter of Credit Amendment”). The Original Letter of Credit as amended by the Letter of Credit Amendment (hereinafter the “Amended Letter of Credit”), is satisfactory to Subcontractor and fully satisfies AMSC’s obligations to deliver a Letter of Credit (as defined in the Agreement) under Section 3.4 of the Agreement;

2. The issuing financial institution of the Amended Letter of Credit will provide at least one hundred and eighty (180) days’ prior written notice of its decision not to renew the Amended Letter of Credit;

3. In the event the issuing financial institution elects not to renew the Amended Letter of Credit, AMSC may utilize up to the then-undrawn amount of the Amended Letter of Credit to fund any replacement standby letter of credit and, in the event AMSC obtains such replacement standby letter of credit, neither the expiration nor replacement of the Amended Letter of Credit shall be deemed a breach by AMSC of the Agreement that would entitle Subcontractor to draw upon the replacement standby letter of credit;

4. Subcontractor may immediately draw on the Amended Letter of Credit upon providing written notice of its intent to do so in the event AMSC has not provided Subcontractor a replacement standby letter of credit in conformance with the terms of the Agreement within ninety (90) days of the issuing financial institution’s notice of non-renewal of the Amended Letter of Credit, provided, that, to the extent Subcontractor is able to and does draw the full undrawn amount of the Amended Letter of Credit, the failure of AMSC to provide a replacement standby letter of credit in accordance with this letter shall not, by itself, permit Subcontractor to terminate the Agreement pursuant to Section 2.2.2 thereof. AMSC shall promptly notify Subcontractor of any such non-renewal decision by the issuing financial institution and provide copies of any notices received from such institution relating thereto;

5. Upon drawing funds from the Amended Letter of Credit (the “LoC Funds”), Subcontractor shall immediately segregate the funds and shall hold them in trust solely for the benefit of the Parties in connection with their respective rights and obligations under the Agreement. Subcontractor may only withdraw monies from the LoC Funds to which it is entitled under the terms of the Agreement. Subcontractor shall provide to AMSC the same documentation as required in the Agreement and adhere to all conditions prescribed therein in respect of any and all draws it makes against the LoC Funds;

6. Subcontractor shall promptly return any LoC Funds that remain undrawn and that are not entitled to be drawn pursuant to the Agreement or otherwise subject to a good faith dispute relating thereto following the earlier to occur of (i) sixty (60) days after final, unconditional and non-appealable acceptance of the HTS Cable System (as defined in the Agreement) into the rate base, or (ii) termination of the Warranty Period (as defined in the Agreement), unless the Agreement has already been terminated or cancelled by Subcontractor or the LoC Funds otherwise have been drawn in full by Subcontractor; and

7. To the maximum extent necessary to give effect to the provisions of this letter, the parties agree that this letter constitutes an amendment to the Agreement. In the event of ambiguous or contradictory language between the Agreement and this letter, the terms and conditions set forth in this letter shall govern and control. Except as amended herein, all terms of the Agreement are unchanged and are in full force and effect.

If the foregoing is acceptable to you, please acknowledge your agreement by signing where indicated below.

Sincerely,

COMMONWEALTH EDISON

Revenue from Contract with Customer [Text Block]

3.

Revenue Recognition

The Company’s revenues in its Grid segment are derived primarily through enabling the transmission and distribution of power, providing planning services that allow it to identify power grid needs and risks, and developing ship protection systems for the U.S. Navy. The Company’s revenues in its Wind segment are derived primarily through supplying advanced power electronics and control systems, licensing its highly engineered wind turbine designs, and providing extensive customer support services to wind turbine manufacturers. The Company records revenue based on a

five

-step model in accordance with ASC

606.

For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. As of

March 31, 2020

, 

72

% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.

In the Company's equipment and system product line, each contract with a customer summarizes each product sold to a customer, which typically represents distinct performance obligations. A contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales transfer control to the customer in line with the contracted delivery terms and revenue is recorded at the point in time when title and risk transfer to the customer, as the Company has determined that this is the point in time that control transfers to the customer.

The Company's equipment and system product line includes certain contracts which do

not

meet the requirements of an exchange transaction and therefore do

not

fall within the scope of ASC

606.

  As these non-exchange transaction contracts are considered grant revenue and do

not

fall within any specific accounting literature, the Company follows guidance within ASC

606

by analogy to recognize grant revenue over time.  In the year ended

March 31, 2020

, the Company recorded $

6.4

 million in grant revenue, which is included in the Company’s Grid revenue. There was

no

grant revenue in the year ended

March 31, 2019

.

In the Company's service and technology development product line, there are several different types of transactions and each begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. The technology development transactions are primarily for activities that have

no

alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are

not

deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is

not

assured and a contract does

not

exist under ASC

606,

revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are

no

further remaining performance obligations.

The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer which occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided the revenue is recognized over time ratably.

The Company’s policy is to

not

accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.

The Company provides assurance-type warranties on all product sales for a term of typically 

one

 to 

three

years, and extended service-type warranties at the customers’ option for an additional term ranging up to 

four

 additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the services.

The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized. The Company has elected to recognize incremental costs of obtaining a contract as expense when incurred except in contracts where the amortization period would exceed

twelve

months; in such cases the long term amount will be assessed for materiality. The Company has elected to

not

adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is

twelve

months or less. 

The Company’s contracts with customers do

not

typically include extended payment terms and

may

include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from

30

to

60

days from delivery.

The following tables disaggregate the Company’s revenue by product line and by shipment destination:

In the fiscal years ended 

March 31, 2020

and

2019

,

51%

 and

74%

of the Company’s revenues, respectively, were recognized from sales outside the United States. The Company maintains operations in Austria, Romania, and the United States and sales and service support centers around the world.

As of

March 31, 2020

and

March 31, 2019

, the Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances. Changes in the Company’s contract assets, which are included in “Unbilled Accounts Receivable” and “De

ferred program costs” (see Note

6,

“Accounts Receivable” and Note

7,

“Inventory” for a reconciliation to the condensed consolidated balance sheet) and contract liabilities, which are included in the current portion and long term portion of “deferred revenue” in the Company’s condensed consolidated balance sheets, are as follows:

	Unbilled AR			Deferred Program Costs			Contract Liabilities

The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations

may

vary significantly each reporting period based on the timing of major new contractual commitments. As of

March 31, 2020

, the Company had outstanding performance obligations on existing contracts under ASC

606

to be recognized in the next 

twelve

twelve

month rolling forecast provided by Inox on the multi-year supply contract. The quantities specified in any forecast provided by Inox related to the multi-year supply contract are firm and irrevocable for the

Business Segments

The Company reports its financial results in

two

reportable business segments: Grid and Wind.

Through the Company’s power grid offerings, the Grid business segment enables electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through its transmission planning services, power electronics, and superconductor-based systems. The sales process is enabled by transmission planning services that allow it to identify power grid congestion, poor power quality and other risks, which helps the Company determine how its solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems.  The Company also sells ship protection products to the U.S. Navy through its Grid business segment.

Through the Company’s wind power offerings, the Wind business segment enables manufacturers to field highly competitive wind turbines through its advanced power electronics and control system products, engineered designs, and support services. The Company supplies advanced power electronics and control systems, licenses its highly engineered wind turbine designs, and provides extensive customer support services to wind turbine manufacturers. The Company’s design portfolio includes a broad range of drive trains and power ratings of

2

megawatts ("MWs") and higher. The Company provides a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

The

operating

results for the

two

business segments are as follows (in thousands):

Wind		14,250		8,167
Corporate assets		65,815		80,088
Total	$	124,109	$	119,330

The accounting policies of the business segments are the same as those for the consolidated Company. The Company’s business segments have been determined in accordance with the Company’s internal management structure, which is organized based on operating activities. The Company evaluates performance based upon several factors, of which the primary financial measures are segment revenues and segment operating income (loss). The disaggregated financial results of the segments reflect allocation of certain functional expense categories consistent with the basis and manner in which Company management internally disaggregates financial information for the purpose of assisting in making internal operating decisions. In addition, certain corporate expenses which the Company does

not

believe are specifically attributable or allocable to either of the

two

business segments have been excluded from the segment operating income (loss).

Unallocated corporate expenses primarily consist of stock-based compensation expense of $

1.9

million and

$3.0

 million, in the fiscal years ended

March 31, 2020

and

2019

Stock-Based Compensation Plans

As of

March 31, 2020

, the Company had

two

active stock plans: the

2007

Stock Incentive Plan, as amended (the

“2007

Plan”) and the Amended and Restated

2007

Director Stock Plan (the

“2007

Director Plan”).  On

August 1, 2019,

the Company’s stockholders approved amendments to the

2007

Plan and the

2007

Director Plan. The amendment to the

2007

Plan increased the total number of shares of common stock authorized for issuance under the

2007

Plan from

3,400,000

shares to

4,600,000

shares. The amendment to the

2007

Director Plan increased the total number of shares of common stock authorized for issuance under the

2007

Director Plan from

230,000

shares to

280,000

shares.

The

2007

Plan provides for the grant of incentive stock options intended to qualify under Section 

422

of the IRC of

1986,

as amended, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards. In the case of options, the exercise price is

no

less than the fair market value of the common stock, as determined by (or in a manner approved by) the Board of Directors, on the date of grant. The contractual life of options is generally

10

years. Options generally vest over a

3

-

5

year period while restricted stock generally vests over a

3

year period.

The

2007

Director Plan provides for the grant of nonstatutory stock options and stock awards to members of the Board of Directors who are

not

also employees of the Company ("outside directors"). Under the terms of the

2007

Director Plan, each outside director is granted an option to purchase shares of common stock with an aggregate grant date value equal to

$40,000

upon his or her initial election to the Board with an exercise price equal to the fair market value of the Company’s common stock on the date of the grant. These options vest in equal annual installments over a

two

-year period. In addition, each outside director is granted an award of shares of common stock with an aggregate grant date value equal to

$40,000

as of the closing price

three

 business days following the last day of each fiscal year, subject to proration for any partial fiscal year of service.

As of

March 31, 2020

, the

2007

Plan had

1,249,930

 shares available for future issuance and the

2007

Director Plan had

108,474

 shares available for future issuance.

Significant Accounting Policies [Text Block]

 Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain reclassifications of prior years’ amounts have been made to conform to the current year presentation. These reclassifications had

no

effect on net income, cash flows from operating activities or stockholders’ equity.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are

not

readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, goodwill and intangible assets, warranty provisions, stock-based compensation, tax reserves, and deferred tax assets. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and, consequently, actual results

may

differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by the Company’s management there

may

be other estimates or assumptions that are reasonable, the Company believes that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements.

Cash Equivalents

Cash equivalents consist of highly liquid instruments with maturities of

three

months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level

1

of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than

12

months that are measured using such inputs as quoted prices and are classified within Level

1

of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net.  The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of allowances for doubtful accounts. The Company’s accounts receivable relate principally to a limited number of customers. As of

March 31, 2020

 Fuji Bridex Pte. Ltd. accounted for approximately

25%,

Department of Homeland Security accounted for

18%,

and Doosan Heavy Industries & Construction Co., Ltd. accounted for approximately

17%

of the Company's total receivable balance, with

no

other customer accounting for greater than

10%

of the balance.  As of

March 31, 2019

, Vestas accounted for approximately

21%

and RES System

3,

LLC accounted for approximately

16%

of the Company’s total receivable balance, with

no

other customer accounting for greater than

10%

of the balance.  Changes in the financial condition or operations of the Company’s customers

may

result in delayed payments or non-payments which would adversely impact its cash flows from operating activities and/or its results of operations. As such, the Company

may

require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In determining the allowance for doubtful accounts, the Company evaluates the collectability of accounts receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due receivables, specific customer circumstances, and current economic trends. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances

may

be required. Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on the Company’s business, financial condition, results of operations, and cash flows.

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost, determined on a

first

-in,

first

-out basis, or net realizable value determined on a

first

-in,

first

-out basis as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company records inventory when it takes delivery and title to the product according to the terms of each supply contract.

Program costs

may

be deferred and recorded as inventory on contracts on which costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

At each balance sheet date, the Company evaluates its ending inventories for excess quantities and obsolescence. Inventories that management considers excess or obsolete are reserved. Management considers forecasted demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is

not

written back up if demand increases.

For the fiscal years ended

March 31, 2020

and

2019

, the Company recorded inventory reserves of approximately $

1.3

 million and

$0.9

 million, respectively, based on evaluating its ending inventory on hand for excess quantities and obsolescence.

Leases

Leases include all agreements in which we obtain control of a physical asset.  Leases are captured on the balance sheet as both a right of use asset and associated lease liability and are valued based on the commencement of our control of the asset, after being discounted by our incremental borrowing rate.  Our lease portfolio is made up primarily of real estate leases for our various offices, but also include items such as vehicles, IT equipment and other miscellaneous tools and equipment needed for manufacturing.  Our incremental borrowing rate was determined through an analysis to identify what rates we could obtain if we were to secure external financing for similar transactions, and includes considerations of both the market and our current credit ratings.  An analysis is performed annually, or upon execution of any individually material agreement, to ensure that the rates being applied to newly acquired leases are still accurate.

The majority of the Company's leases are classified as operating leases, and therefore the expense is captured in income from operations each period.

We have elected to exclude all leases of less than

twelve

months from the balance sheet presentation.  We have also elected a policy in which we will

not

segregate lease components from non-lease components, so in the event we execute an agreement which includes a non-lease component our asset and liability recorded to the balance sheet will include the value of that non-lease component as well.  This policy will be applied to all classifications of leases.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and amortization. The Company accounts for depreciation and amortization using the straight-line method to allocate the cost of property, plant and equipment over their estimated useful lives as follows:

Asset Classification	Estimated Useful Life in Years
Machinery and equipment	3-10
Furniture and fixtures	3-5
Leasehold improvements	Shorter of the estimated useful life or the remaining lease term

Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the costs and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in operating expenses.

Valuation of Long-Lived Assets

The Company periodically evaluates its long-lived assets, consisting principally of fixed assets and amortizable intangible assets, for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived assets, the Company reviews the carrying value of its long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of the assets

may

not

be recoverable. Under the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The Company evaluates its long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets

may

not

be recoverable from the estimated undiscounted future cash flows.

There were

no

indicators requiring impairment testing on the Company's long-lived assets during the fiscal years ended 

March 31, 2020

and

2019

.

Goodwill

Goodwill represents the excess of cost over net assets of acquired businesses that are consolidated. The Company performs its annual assessment of goodwill on

February

28th

of each fiscal year and whenever events or changes in circumstances or a triggering event indicate that the carrying amount

may

not

be recoverable. Determining whether a triggering event has occurred often involves significant judgment from management. An entity is permitted to

first

assess qualitatively whether it is necessary to perform a goodwill impairment test. The quantitative impairment test is required only if the entity concludes that it is more likely than

not

that a reporting unit’s fair value is less than its carrying amount. The Company determines the fair value of a reporting unit based on an income approach utilizing a discounted cash flow adjusted for entity specific factors. In evaluating whether it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount, an entity should consider the totality of all relevant events or circumstances that affect the fair value or carrying amount of a reporting unit.  If the carrying value of a reporting unit exceeds the reporting unit’s fair value, then an impairment charge is recognized reducing the goodwill by the excess of the carrying amount over the fair value,

not

to exceed the total amount of the goodwill allocated to the that reporting unit. See Note

4,

"Acquisition and Related Goodwill" for further information and discussion.

The Company performed its annual assessment of goodwill on

Revenue Recognition

Revenue contracts are defined as an arrangement that creates enforceable rights and obligations of both parties where collection of the contract price is deemed probable.

The Company records revenue based on a

five

-step model which includes confirmation of contract existence, identifying the performance obligations, determining the transaction price, allocating the contract transaction price to the performance obligations, and recognizing the revenue when (or as) control of goods or services is transferred to the customer. The transfer of control

can occur at the time of delivery, installation or post-installation where applicable. 

The Company's equipment and system product line includes certain contracts which do

not

meet the requirements of an exchange transaction and therefore do

not

fall within the scope of ASC

606.

  As these non-exchange transaction contracts are considered grant revenue and do

not

fall within any specific accounting literature, the Company follows guidance within ASC

606

by analogy to recognize grant revenue over time. 

For certain arrangements, such as contracts to perform research and development, prototype development contracts and certain customized product sales, the Company records revenues using the over-time method, measured by the relationship of costs incurred to total estimated contract costs. Over-time revenue recognition accounting is predominantly used on certain turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government. The Company follows this method when any of the

three

following criteria are met: when the customer receives the benefits as they are performed, control transfers to the customer as the work is performed, or there is

no

alternative use to the Company and there is an enforceable right to payment through the life of the contract. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. For contracts where reasonably dependable estimates of the revenues and costs cannot be made, the Company follows the point in time method.

The Company enters into sales arrangements that

may

provide for multiple performance obligations to a customer. Sales of certain products

may

include extended warranty and support or service packages, and at times include performance bonds. As these contracts progress, the Company continually assesses the probability of a payout from the performance bond. Should the Company determine that such a payout is likely; the Company would record a liability. The Company would reduce revenue to the extent a liability is recorded. In addition, the Company enters into licensing arrangements that include training services.

Performance obligations are separated into more than

one

unit of accounting when (

1

) the delivered element(s) have value to the customer on a stand-alone basis, and (

2

) the Company's promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract.  In general, revenues are separated between the different product shipments which have stand-alone value, and the various services to be provided. Revenue for product shipments is generally recognized at a point in time where control of the product is transferred to the customer, while revenues for the services are generally recognized over the period of performance. The Company identifies all goods and/or services that are to be delivered separately under a sales arrangement and

allocates the transaction price to each distinct performance obligation using the respective standalone selling price ("SSP") which is determined primarily using the cost plus expected margin approach for products and a relief from royalty method for licenses.  Revenue allocated to each performance obligation is recognized when, or as, the performance obligation is satisfied. 

The Company reviews SSP and the related margins at least annually.

The Company’s license agreements provide either for the payment of contractually determined paid-up front license fees or milestone based payments in consideration for the grant of rights to manufacture and or sell products using its patented technologies or know-how. Some of these agreements provide for the release of the licensee from past and future intellectual property infringement claims. When the Company can determine that it has

no

further obligations other than the grant of the license and that the Company has fully transferred the technology know-how, the Company recognizes the revenue under a point in time model. In other license arrangements, the Company

may

also agree to provide training services to transfer the technology know-how.  In these arrangements, the Company has determined that the licenses have

no

standalone value to the customer and are

not

separable from training services as the Company can only fully transfer the technology know-how through the training component. Accordingly, the Company accounts for these arrangements as a single unit of accounting, and recognizes revenue over the period of its performance using the over-time method. Costs for these arrangements are expensed as incurred.

Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability of any portion of the contract value is

not

probable, an analysis of variable consideration will be performed using either the most likely amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability has been resolved. For contractual arrangements that involve variable consideration, the Company recognizes revenue for these amounts upon reaching the constraining event successfully.  The Company does

not

generally provide for extended payment terms or provide its customers with a right of return.

The Company has elected to record taxes collected from customers on a net basis and does

not

include tax amounts in revenue or costs of revenue.

The Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances.

Revenue from Contracts with Customers

.

Product Warranty

Warranty obligations are incurred in connection with the sale of the Company’s products.  The Company provides assurance-type warranties on all product sales for a term of typically 

one

 to 

three

years, and extended service-type warranties at the customers’ option for an additional term ranging up to 

four

 additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the service.  The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates and related costs to repair given products. The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the estimated warranty liability would be required.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

The Company’s provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carry-forwards using expected tax rates in effect in the years during which the differences are expected to reverse.

Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each fiscal year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. The Company has provided a valuation allowance against its U.S. and China deferred income tax assets since the Company believes that it is more likely than

not

that these deferred tax assets are

not

currently realizable due to uncertainty around profitability in the future.

Accounting for income taxes requires a

two

-step approach to recognizing and measuring uncertain tax positions. The

first

step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than

not

that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The

second

step is to measure the tax benefit as the largest amount that is more than

50%

likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but

not

limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company includes interest and penalties related to gross unrecognized tax benefits within the provision for income taxes.  See Note

13,

“Income Taxes,” for further information regarding its income tax assumptions and expenses.

Stock-Based Compensation

The Company accounts for stock-based payment transactions using a fair value-based method and recognizes the related expense in the results of operations.

Stock-based compensation is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period of the award. The fair value of restricted stock awards is determined by reference to the fair market value of the Company’s common stock on the date of grant. The Company uses the Black-Scholes option pricing model to estimate the fair value of awards with service and performance conditions. For awards with service conditions only, the Company recognizes compensation cost on a straight-line basis over the requisite service/vesting period. For awards with performance conditions, accruals of compensation cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatilities of the Company’s common stock and expected terms. The expected volatility rates are estimated based on historical and implied volatilities of the Company’s common stock. The expected term represents the average time that the options that vest are expected to be outstanding based on the vesting provisions and the Company’s historical exercise, cancellation and expiration patterns.

The Company estimates pre-vesting forfeitures when recognizing compensation expense based on historical and forward-looking factors. Changes in estimated forfeiture rates and differences between estimated forfeiture rates and actual experience

may

result in significant, unanticipated increases or decreases in stock-based compensation expense from period to period. The termination of employment of certain employees who hold large numbers of stock-based awards

may

also have a significant, unanticipated impact on forfeiture experience and, therefore, on stock-based compensation expense. The Company will update these assumptions on at least an annual basis and on an interim basis if significant changes to the assumptions are warranted.

The Company accounts 

for share-based payments made to non-employees 

in the same manner as other share-based payments for employees, with the measurement being based on the fair value at the grant date.   The non-employee share based payments will be included within the Company's stock compensation currently reported.

Computation of Net Income (Loss) per Common Share

Basic net income (loss) per share (“EPS”) is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing the net loss by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. For the fiscal years ended 

March 31, 2020

and

2019

, common equivalent shares of

354,748,

and

907,988,

respectively, were

not

included in the calculation of diluted EPS as they were considered antidilutive. The following table

reconciles

Foreign Currency Translation

The functional currency of all the Company’s foreign subsidiaries is the U.S. dollar, except for AMSC Austria, for which the local currency (Euro) is the functional currency, and AMSC China, for which the local currency (Renminbi) is the functional currency. The assets and liabilities of AMSC Austria and AMSC China are translated into U.S. dollars at the exchange rate in effect at the balance sheet date and income and expense items are translated at average rates for the period. Cumulative translation adjustments are excluded from net loss (income) and shown as a separate component of stockholders’ equity. Net foreign currency gains and losses are included in other income (expense), net on the consolidated statements of operations and were $

0.1

 million and

$1.6

million, for the fiscal years ended 

March 31, 2020

and

2019

, respectively. The Company has

no

restrictions on the foreign exchange activities of its foreign subsidiaries, including the payment of dividends and other distributions.

Risks and Uncertainties

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates and would impact future results of operations and cash flows.

The Company invests its available cash in high credit, quality financial instruments and invests primarily in investment-grade marketable securities, including, but

not

limited to, government obligations, money market funds and corporate debt instruments.

Several of the Company’s government contracts are being funded incrementally, and as such, are subject to the future authorization, appropriation, and availability of government funding. The Company has a history of successfully obtaining financing under incrementally-funded contracts with the U.S. government and it expects to continue to obtain additional contract modifications in the year ending

March 

31,

2021

 and beyond as incremental funding is authorized and appropriated by the government.

Contingencies

From time to time, the Company

may

be involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. Management reviews these estimates in each accounting period as additional information is known and adjusts the loss provision when appropriate. If the loss is

not

probable or cannot be reasonably estimated, a liability is

not

recorded in the consolidated financial statements. If, with respect to a matter, it is

not

both probable to result in liability and the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss is disclosed unless such an estimate cannot be made. The Company does

not

recognize gain contingencies until they are realized. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note

16,

“Commitments and Contingencies,” for further information.

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments consist principally of cash and cash equivalents, accounts receivable, marketable securities, accounts payable, accrued expenses, warrants to purchase shares of common stock, and derivatives. The carrying amounts of cash and cash equivalents, accounts receivable, short-term debt, accounts payable, and accrued expenses due to their short nature approximate fair value at 

March 31, 2020

and

2019

. The estimated fair values have been determined through information obtained from market sources and management estimates.  Marketable securities consist of certificates of deposit with maturities of greater than

12

months that are measured using such inputs as quoted prices and are classified within Level

1

of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net. The fair value for the warrant arrangements was historically estimated by management based on various assumptions in a lattice model and was subject to revaluation at each balance sheet date.  The Company classifies the estimates used to fair value these instruments as Level

3

inputs. See Note

5,

“Fair Value Measurements” for a full discussion on fair value measurements.

Commitments and Contingencies

Purchase Commitments

The Company periodically enters into non-cancelable purchase contracts in order to ensure the availability of materials to support production of its products. Purchase commitments represent enforceable and legally binding agreements with suppliers to purchase goods or services. The Company periodically assesses the need to provide for impairment on these purchase contracts and record a loss on purchase commitments when required.

Lease Commitments

During the year ended 

March 31, 2020

all leases were recorded in Lease expense.  See Note

14,

"Leases" for further details.  For the year ended 

March 31, 2019

 rent expense was

$1.3

million.  See Item

2,

“Properties” for further information.

Legal Contingencies

From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements

not

misleading. If the loss is

not

probable or cannot be reasonably estimated, a liability is

not

recorded in its consolidated financial statements.

Other

The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all the face amount of the performance bonds into an escrow account until the termination of the bond. When the performance conditions are met, amounts deposited as collateral for the performance bonds are returned to the Company. In addition, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

As of

March 31, 2020

, the Company had $

5.7

 million of restricted cash included in long-term assets and $

0.5

 million of restricted cash in current assets. These amounts included in restricted cash primarily represent deposits to secure letters of credit for various supply contracts including the irrevocable letter of credit in the amount of

$5.0

million to secure certain of the Company’s obligations under the Subcontract Agreement with Commonwealth Edison Company. These deposits are held in interest bearing accounts.

Nature of the Business and Operations and Liquidity

Nature of the Business and Operations

American Superconductor Corporation (together with its subsidiaries, “AMSC®” or the “Company”) was founded on

April 

9,

1987.

The Company is a leading system provider of megawatt-scale power solutions that enhance the performance of the power grid, protect the Navy’s fleet, and lower the cost of wind power. The Company’s products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.

The Company’s consolidated financial statements have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form

10

-K. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Liquidity

The Company has historically experienced recurring operating losses and as of

March 31, 2020

, the Company had an accumulated deficit of $

978.6

 million. In addition, the Company has historically experienced recurring negative operating cash flows.  At

March 31, 2020

, the Company had cash, cash equivalents, and marketable securities of $

59.9

 million. Marketable securities include certificate of deposits with maturities between

eleven

and

eighteen

months.  Cash used in operations for the year ended 

March 31, 2020

was $

16.5

 million.

On

July 

3,

2018,

the Company and its wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GMBH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settled the litigation and arbitration proceedings between the Company and Sinovel. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to

$57.5

million, consisting of

two

installments. Sinovel paid the

first

installment of the RMB equivalent of

$32.5

million on

July 

4,

2018,

which was repatriated to the U.S. entity during the

nine

months ended

December 

31,

2018,

and paid the

second

installment of the RMB equivalent of

$25.0

million on

December 27, 2018. 

The Company's fiscal

2018

results include the net gain received from the settlement with Sinovel of

$52.7

million.

On

February 1, 2018,

ASC Devens LLC (the “Seller”), a wholly-owned subsidiary of the Company, entered into a Purchase and Sale Agreement (the “PSA”) with

64

Jackson, LLC (the “Purchaser”) and Stewart Title Guaranty Company (“Escrow Agent”), to effectuate the sale of certain real property located at

64

Jackson Road, Devens, Massachusetts, including the building that had served as the Company’s headquarters (collectively, the “Property”), in exchange for total consideration of

$23.0

million, composed of (i) cash consideration of

$17.0

million, and (ii) a

$6.0

million subordinated secured commercial promissory note payable to the Company (the “Seller Note”). Subsequently, the Seller, the Purchaser and Jackson

64

MGI, LLC (“Assignee”) entered into an Assignment of Purchase and Sale Agreement (the “Assignment Agreement”), pursuant to which the Purchaser assigned all of its rights and interests in the PSA to the Assignee and the Assignee agreed to assume all of the Purchaser’s obligations and liabilities under the PSA. The transaction closed on

March 28, 2018,

at which time the Company received, from the Assignee, cash consideration, net of certain agreed upon closing costs, of

$16.9

million, and the Seller Note at an interest rate of

1.96%.

The Seller Note is secured by a subordinated

second

mortgage on the Property and a subordinated

second

assignment of leases and rents.  The Company received the

first

$3.0

million payment due pursuant to the Seller Note on

March 28, 2019 

and the

second

$3.0

million payment plus interest on

May 23, 2019.

In

December 2015,

the Company entered into a set of strategic agreements valued at approximately

$210.0

million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems to Inox and a license agreement allowing Inox to manufacture a limited number of electrical control systems. After Inox purchases the specified number of electrical control systems required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its electrical control systems requirements for an additional

three

-year period.  Pursuant to these strategic agreements, Inox must forecast future purchase orders of sets of Electrical Control Systems ("ECS") which become firm orders

three

months prior to shipment, and Inox must post letters of credit before the Company will ship such orders. Inox is currently delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On

May 29, 2020,

the Company sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of

€6.0

million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox fails to post letters of credit in the amount of

€6.0

million in accordance with the terms of the supply contract within the

ninety

day cure period after receipt of the default notice, then the Company

may

terminate the supply contract by providing written notice of such termination to Inox.  We cannot predict if and when Inox will post letters of credit consistent with the forecasted ECS quantities. Inox’s failure to post letters of credit and take delivery of forecasted ECS quantities would impact the Company’s revenues and liquidity.  In the event the Company were to terminate the supply contract, the Company's revenues and liquidity would be impacted.

The Company issued warrants in conjunction with an equity offering to Hudson Bay Capital ("Hudson") in

November 2014 (

the "Hudson Warrant").  The Hudson Warrant was partially exercised on

November 13, 2019

with an exercise price of

$7.81.

The Company received

$6.1

million in cash for the exercise of

786,000

warrants. The remaining

32,181

warrants expired unexercised on

November 13, 2019.

In

March 2020,

the World Health Organization declared the disease caused by the novel coronavirus (“COVID-

19“

) to be a pandemic. COVID-

19

 has spread throughout the globe, including in the Commonwealth of Massachusetts where the Company’s headquarters are located, and in other areas where the Company has business operations. In response to the outbreak, the Company has followed the guidelines of the U.S. Centers for Disease Control and Prevention (“CDC”) and applicable state government authorities to protect the health and safety of the Company’s employees, families, suppliers, customers and communities. While these existing measures and, COVID-

19

generally, have

not

materially disrupted the Company’s business to date, any future actions necessitated by the COVID-

19

pandemic

may

result in disruption to the Company’s business.

While the COVID-

19

pandemic continues to rapidly evolve, the Company continues to assess the impact of the COVID-

19

pandemic to best mitigate risk and continue the operations of the Company’s business. The extent to which the outbreak impacts the Company’s business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including new information that

may

emerge concerning the severity of the COVID-

19

pandemic and the actions to contain it or treat its impact, among others.  If the Company, its customers or suppliers experience prolonged shutdowns or other business disruptions, the Company’s business, liquidity, results of operations and financial condition are likely to be materially adversely affected, and the Company’s ability to access the capital markets

may

be limited. 

The Company believes that based on the information presented above and its annual management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next

twelve

months following the issuance of the financial statements for the year ended 

March 31, 2020

. The Company’s liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary. The impact of the COVID-

19

pandemic on the global financing markets

may

reduce the Company's ability to raise additional capital, if necessary, which could negatively impact the Company's liquidity.  There can be

no

assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above.

Warrants and Derivative Liabilities

The Company accounts for its warrants as liabilities due to certain adjustment provisions within the instruments, which require that they be recorded at fair value. The warrants are subject to revaluation at each balance sheet date and any change in fair value is recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note

5,

“Fair Value Measurements” for further discussion.

Hercules Warrant

The Company issued Hercules warrants to purchase

13,927

shares of common stock (the “First Warrant”) and

25,641

shares of common stock (the “Second Warrant”) in conjunction with prior term loans that have been repaid in full. On

December 19, 2014,

the Company entered into a

second

amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued Hercules a warrant to purchase

58,823

shares of the Company’s common stock (the "Hercules Warrant") which replaced the First Warrant and the Second Warrant.  The Hercules Warrant was exercisable at any time after its issuance at an exercise price of

$7.85

per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in

May 2017,

the acquisition of Infinia Technology Corporation ("ITC") with common stock in

September 2017

and sales of common stock under the ATM entered into in

January 2017.  

This warrant had a fair value of

$0.4

million as of

March 31, 2019

and

$0.1

million as of

March 31, 2018. 

On

April 8, 2019

Hercules notified the Company of its intent to exercise this warrant on a cashless basis.  Hercules received

22,821

shares of the Company's common stock on

April 17, 2019.  

As a result of this exercise the Company recorded a net gain of

$0.1

million to change in fair value of warrants, resulting from the decrease in the fair value of the Hercules Warrant during the year ended

March 31, 2020. 

The Company recorded a net loss of

$0.2

million to change in fair value of warrants, resulting from the increase in the fair value of the Hercules Warrant during the year ended

March 31, 2019.

November 2014

Warrant

On

November 13, 2014,

the Company completed an offering of

909,090

units of the Company’s common stock with Hudson Bay Capital. Each unit consisted of

one

share of the Company’s common stock and

0.9

of a warrant to purchase

one

share of common stock, or a warrant to purchase in the aggregate

818,181

shares (the

“November 2014

Warrant”).  The

November 2014

Warrant was exercisable at any time, at an exercise price equal to

$7.81

per share, subject to certain price-based and other anti-dilution adjustments including those noted above.  On

November 13, 2019,

Hudson partially exercised the

November 2014

Warrant for

786,000

restricted shares of Company common stock at

$7.81

per share.  The remaining

32,181

warrants expired unexercised on

November 13, 2019.

As a result of this exercise the Company recorded a net gain 

$4.6

million to change in fair value of warrants, resulting from the decrease in the fair value of the

November 2014

Warrant during the year ended

March 31, 2020

, and a net loss, resulting from an increase in the fair value of the

November 2014

Warrant, of

$3.5

 million to change in fair value of derivatives and warrants in the fiscal year ended 

March 31, 2019

. As of

March 31, 2020

Note Receivable

AMSC entered into a purchase and sale agreement dated

February 1, 2018

for the Devens facility (including land, building and building improvements) located at

64

Jackson Road, Devens, Massachusetts to

64

Jackson Road, LLC, a limited liability company, in the amount of

$23.0

million. The terms for payment included a

$1.0

million security deposit, and a note receivable for

$6.0

million payable to AMSC with the remaining cash net of certain adjustments for closing costs at the date of settlement.

The note receivable was due in

two

$3.0

million installments plus accrued interest at

1.96%

rate.  The

first

installment was paid on

March 28, 2019

and the

second

installment was paid

May 23, 2019.

The note was subordinate to East Boston Savings Bank's mortgage on the Devens property. The note receivable was discounted to its present value of

$5.7

million utilizing a discount rate of

6%,

which was based on management’s assessment of what an appropriate loan at current market rate would be. The

$0.3

million discount was recorded as an offset to the long term portion of the note receivable.  As of

March 31, 2019,

the remaining

$0.1

million discount was being amortized to interest income as an offset to the short-term portion of the note, over the remaining term of the note.

In addition, the resulting gain of

$0.1

million from the sale of the Devens property which was deferred previously was recorded as a component of the cumulative effect of an accounting change upon the adoption of ASU

2017

-

05

which was issued as a part of ASU

2014

-

09.

This gain was recorded as an offset to the opening accumulated deficit as of

Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic

420,

Exit or Disposal Cost Obligations

(“ASC

420”

) and ASC Topic

712,

Compensation—Nonretirement Postemployment Benefits

(“ASC

712”

). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.

The

$0.5

million charged to operations in the fiscal year ended

March 31, 2019

was related to exit costs incurred primarily during the

first

half of fiscal

2018

for the move of the Company's corporate office.

The following table presents restructuring charges and cash payments during the year ended

March 31, 2019 (

Leases

On

April 1, 2019,

the Company adopted ASU

2016

-

02,

Leases (Topic

842

)

("ASC

842"

), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did

not

reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company did

not

elect the hindsight practical expedient and evaluated lease terms for existing leases. The Company has also elected the practical expedient to

not

separate lease components and non-lease components and will account for the leases as a single lease component for all classes of leases.

As a result of the adoption of ASC

842,

the Company recognized lease right-of-use assets of

$3.8

million, and operating lease liabilities of

$3.8

million. There was

no

impact to the condensed consolidated statements of operations or stockholders' equity for the adoption of ASC

842.

No

impairment was recognized on the right-of-use asset upon adoption. These adjustments are detailed as follows:

	March 31, 2019		ASC 842 Adjustment		April 1, 2019
Operating Leases:
Right of use asset	$	—	$	3,795	$	3,795
Total operating lease right-of-use asset		—		3,795		3,795
Operating lease liabilities – ST	$	—	$	309	$	309
Operating lease liabilities – LT		—		3,512		3,512
Total operating lease liabilities		—		3,821		3,821
Weighted-average remaining lease term					7.69 years
Weighted-average discount rate						7.06	%

All significant lease arrangements are recognized at lease commencement.  Operating lease right–of-use assets and lease liabilities are recognized at commencement. The operating lease right-of-use asset includes any lease payments related to initial direct cost and prepayments and excludes any lease incentives. Lease expense is recognized on a straight-line basis over the lease term.  The Company enters into a variety of operating lease agreements through the normal course of its business, but primarily real estate leases to support its operations. The agreements generally provide for fixed minimum rental payments and the payment of real estate taxes and insurance. Many of these leases have

one

or more renewal options that allow the Company, at its discretion, to renew the lease for varying periods up to

five

years or to terminate the lease. Only renewal options or termination rights that the Company believed were likely to be exercised were included in the lease calculations.

The Company also enters into leases for vehicles, IT equipment and service agreements, and other leases related to its manufacturing operations that are also included in the right-of-use asset and lease liability accounts if they are for a term of longer than

twelve

months. However, many of these leases are either short-term in nature or immaterial. The Company has made the policy election to exclude short-term leases from the balance sheet. 

The discount rate was calculated using an incremental borrowing rate based on an assessment prepared by the Company through the use of Company credit ratings, consideration of its lease populations potential risk to its total capital structure, and a market rate for a collateralized loan for its risk profile, calculated by a

third

party. The Company elected to apply the discount rate using the remaining lease term at the date of adoption.

The Company did

not

identify any leases that are classified as financing leases.

Supplemental balance sheet information related to leases at

March 31, 2020

Accounting Policies [Abstract]

Nature of Business and Operations, Policy [Policy Text Block]

Nature of the Business and Operations

American Superconductor Corporation (together with its subsidiaries, “AMSC®” or the “Company”) was founded on

April 

9,

1987.

The Company is a leading system provider of megawatt-scale power solutions that enhance the performance of the power grid, protect the Navy’s fleet, and lower the cost of wind power. The Company’s products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.

The Company’s consolidated financial statements have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form

10

-K. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

Liquidity, Policy [Policy Text Block]

Liquidity

The Company has historically experienced recurring operating losses and as of

March 31, 2020

, the Company had an accumulated deficit of $

978.6

 million. In addition, the Company has historically experienced recurring negative operating cash flows.  At

March 31, 2020

, the Company had cash, cash equivalents, and marketable securities of $

59.9

 million. Marketable securities include certificate of deposits with maturities between

eleven

and

eighteen

months.  Cash used in operations for the year ended 

March 31, 2020

was $

16.5

 million.

On

July 

3,

2018,

the Company and its wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GMBH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settled the litigation and arbitration proceedings between the Company and Sinovel. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to

$57.5

million, consisting of

two

installments. Sinovel paid the

first

installment of the RMB equivalent of

$32.5

million on

July 

4,

2018,

which was repatriated to the U.S. entity during the

nine

months ended

December 

31,

2018,

and paid the

second

installment of the RMB equivalent of

$25.0

million on

December 27, 2018. 

The Company's fiscal

2018

results include the net gain received from the settlement with Sinovel of

$52.7

million.

On

February 1, 2018,

ASC Devens LLC (the “Seller”), a wholly-owned subsidiary of the Company, entered into a Purchase and Sale Agreement (the “PSA”) with

64

Jackson, LLC (the “Purchaser”) and Stewart Title Guaranty Company (“Escrow Agent”), to effectuate the sale of certain real property located at

64

Jackson Road, Devens, Massachusetts, including the building that had served as the Company’s headquarters (collectively, the “Property”), in exchange for total consideration of

$23.0

million, composed of (i) cash consideration of

$17.0

million, and (ii) a

$6.0

million subordinated secured commercial promissory note payable to the Company (the “Seller Note”). Subsequently, the Seller, the Purchaser and Jackson

64

MGI, LLC (“Assignee”) entered into an Assignment of Purchase and Sale Agreement (the “Assignment Agreement”), pursuant to which the Purchaser assigned all of its rights and interests in the PSA to the Assignee and the Assignee agreed to assume all of the Purchaser’s obligations and liabilities under the PSA. The transaction closed on

March 28, 2018,

at which time the Company received, from the Assignee, cash consideration, net of certain agreed upon closing costs, of

$16.9

million, and the Seller Note at an interest rate of

1.96%.

The Seller Note is secured by a subordinated

second

mortgage on the Property and a subordinated

second

assignment of leases and rents.  The Company received the

first

$3.0

million payment due pursuant to the Seller Note on

March 28, 2019 

and the

second

$3.0

million payment plus interest on

May 23, 2019.

In

December 2015,

the Company entered into a set of strategic agreements valued at approximately

$210.0

million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems to Inox and a license agreement allowing Inox to manufacture a limited number of electrical control systems. After Inox purchases the specified number of electrical control systems required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its electrical control systems requirements for an additional

three

-year period.  Pursuant to these strategic agreements, Inox must forecast future purchase orders of sets of Electrical Control Systems ("ECS") which become firm orders

three

months prior to shipment, and Inox must post letters of credit before the Company will ship such orders. Inox is currently delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On

May 29, 2020,

the Company sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of

€6.0

million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox fails to post letters of credit in the amount of

€6.0

million in accordance with the terms of the supply contract within the

ninety

day cure period after receipt of the default notice, then the Company

may

terminate the supply contract by providing written notice of such termination to Inox.  We cannot predict if and when Inox will post letters of credit consistent with the forecasted ECS quantities. Inox’s failure to post letters of credit and take delivery of forecasted ECS quantities would impact the Company’s revenues and liquidity.  In the event the Company were to terminate the supply contract, the Company's revenues and liquidity would be impacted.

The Company issued warrants in conjunction with an equity offering to Hudson Bay Capital ("Hudson") in

November 2014 (

the "Hudson Warrant").  The Hudson Warrant was partially exercised on

November 13, 2019

with an exercise price of

$7.81.

The Company received

$6.1

million in cash for the exercise of

786,000

warrants. The remaining

32,181

warrants expired unexercised on

November 13, 2019.

In

March 2020,

the World Health Organization declared the disease caused by the novel coronavirus (“COVID-

19“

) to be a pandemic. COVID-

19

 has spread throughout the globe, including in the Commonwealth of Massachusetts where the Company’s headquarters are located, and in other areas where the Company has business operations. In response to the outbreak, the Company has followed the guidelines of the U.S. Centers for Disease Control and Prevention (“CDC”) and applicable state government authorities to protect the health and safety of the Company’s employees, families, suppliers, customers and communities. While these existing measures and, COVID-

19

generally, have

not

materially disrupted the Company’s business to date, any future actions necessitated by the COVID-

19

pandemic

may

result in disruption to the Company’s business.

While the COVID-

19

pandemic continues to rapidly evolve, the Company continues to assess the impact of the COVID-

19

pandemic to best mitigate risk and continue the operations of the Company’s business. The extent to which the outbreak impacts the Company’s business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including new information that

may

emerge concerning the severity of the COVID-

19

pandemic and the actions to contain it or treat its impact, among others.  If the Company, its customers or suppliers experience prolonged shutdowns or other business disruptions, the Company’s business, liquidity, results of operations and financial condition are likely to be materially adversely affected, and the Company’s ability to access the capital markets

may

be limited. 

The Company believes that based on the information presented above and its annual management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next

twelve

months following the issuance of the financial statements for the year ended 

March 31, 2020

. The Company’s liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary. The impact of the COVID-

19

pandemic on the global financing markets

may

reduce the Company's ability to raise additional capital, if necessary, which could negatively impact the Company's liquidity.  There can be

no

assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above.

Consolidation, Policy [Policy Text Block]

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain reclassifications of prior years’ amounts have been made to conform to the current year presentation. These reclassifications had

no

effect on net income, cash flows from operating activities or stockholders’ equity.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are

not

readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, goodwill and intangible assets, warranty provisions, stock-based compensation, tax reserves, and deferred tax assets. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and, consequently, actual results

may

differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by the Company’s management there

may

be other estimates or assumptions that are reasonable, the Company believes that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash Equivalents

Cash equivalents consist of highly liquid instruments with maturities of

three

months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level

1

of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities, Policy [Policy Text Block]

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than

12

months that are measured using such inputs as quoted prices and are classified within Level

1

of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net.  The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Receivable [Policy Text Block]

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of allowances for doubtful accounts. The Company’s accounts receivable relate principally to a limited number of customers. As of

March 31, 2020

 Fuji Bridex Pte. Ltd. accounted for approximately

25%,

Department of Homeland Security accounted for

18%,

and Doosan Heavy Industries & Construction Co., Ltd. accounted for approximately

17%

of the Company's total receivable balance, with

no

other customer accounting for greater than

10%

of the balance.  As of

March 31, 2019

, Vestas accounted for approximately

21%

and RES System

3,

LLC accounted for approximately

16%

of the Company’s total receivable balance, with

no

other customer accounting for greater than

10%

of the balance.  Changes in the financial condition or operations of the Company’s customers

may

result in delayed payments or non-payments which would adversely impact its cash flows from operating activities and/or its results of operations. As such, the Company

may

require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In determining the allowance for doubtful accounts, the Company evaluates the collectability of accounts receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due receivables, specific customer circumstances, and current economic trends. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances

may

be required. Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on the Company’s business, financial condition, results of operations, and cash flows.

Inventory, Policy [Policy Text Block]

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost, determined on a

first

-in,

first

-out basis, or net realizable value determined on a

first

-in,

first

-out basis as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company records inventory when it takes delivery and title to the product according to the terms of each supply contract.

Program costs

may

be deferred and recorded as inventory on contracts on which costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

At each balance sheet date, the Company evaluates its ending inventories for excess quantities and obsolescence. Inventories that management considers excess or obsolete are reserved. Management considers forecasted demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is

not

written back up if demand increases.

For the fiscal years ended

March 31, 2020

and

2019

, the Company recorded inventory reserves of approximately $

1.3

 million and

$0.9

 million, respectively, based on evaluating its ending inventory on hand for excess quantities and obsolescence.

Lessee, Leases [Policy Text Block]

Leases

Leases include all agreements in which we obtain control of a physical asset.  Leases are captured on the balance sheet as both a right of use asset and associated lease liability and are valued based on the commencement of our control of the asset, after being discounted by our incremental borrowing rate.  Our lease portfolio is made up primarily of real estate leases for our various offices, but also include items such as vehicles, IT equipment and other miscellaneous tools and equipment needed for manufacturing.  Our incremental borrowing rate was determined through an analysis to identify what rates we could obtain if we were to secure external financing for similar transactions, and includes considerations of both the market and our current credit ratings.  An analysis is performed annually, or upon execution of any individually material agreement, to ensure that the rates being applied to newly acquired leases are still accurate.

The majority of the Company's leases are classified as operating leases, and therefore the expense is captured in income from operations each period.

We have elected to exclude all leases of less than

twelve

months from the balance sheet presentation.  We have also elected a policy in which we will

not

segregate lease components from non-lease components, so in the event we execute an agreement which includes a non-lease component our asset and liability recorded to the balance sheet will include the value of that non-lease component as well.  This policy will be applied to all classifications of leases.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and amortization. The Company accounts for depreciation and amortization using the straight-line method to allocate the cost of property, plant and equipment over their estimated useful lives as follows:

Asset Classification	Estimated Useful Life in Years
Machinery and equipment	3-10
Furniture and fixtures	3-5
Leasehold improvements	Shorter of the estimated useful life or the remaining lease term

Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the costs and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in operating expenses.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Valuation of Long-Lived Assets

The Company periodically evaluates its long-lived assets, consisting principally of fixed assets and amortizable intangible assets, for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived assets, the Company reviews the carrying value of its long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of the assets

may

not

be recoverable. Under the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The Company evaluates its long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets

may

not

be recoverable from the estimated undiscounted future cash flows.

There were

no

indicators requiring impairment testing on the Company's long-lived assets during the fiscal years ended 

March 31, 2020

and

2019

.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill

Goodwill represents the excess of cost over net assets of acquired businesses that are consolidated. The Company performs its annual assessment of goodwill on

February

28th

of each fiscal year and whenever events or changes in circumstances or a triggering event indicate that the carrying amount

may

not

be recoverable. Determining whether a triggering event has occurred often involves significant judgment from management. An entity is permitted to

first

assess qualitatively whether it is necessary to perform a goodwill impairment test. The quantitative impairment test is required only if the entity concludes that it is more likely than

not

that a reporting unit’s fair value is less than its carrying amount. The Company determines the fair value of a reporting unit based on an income approach utilizing a discounted cash flow adjusted for entity specific factors. In evaluating whether it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount, an entity should consider the totality of all relevant events or circumstances that affect the fair value or carrying amount of a reporting unit.  If the carrying value of a reporting unit exceeds the reporting unit’s fair value, then an impairment charge is recognized reducing the goodwill by the excess of the carrying amount over the fair value,

not

to exceed the total amount of the goodwill allocated to the that reporting unit. See Note

4,

"Acquisition and Related Goodwill" for further information and discussion.

The Company performed its annual assessment of goodwill on

February 28, 2020

and noted

no

triggering events from the analysis date to

March 31, 2020

and determined that there was

no

impairment to goodwill.  Additionally, there was

no

impairment identified for the fiscal year ended 

March 31, 2019

based on the assessment performed in the prior fiscal year.

Revenue [Policy Text Block]

Revenue Recognition

Revenue contracts are defined as an arrangement that creates enforceable rights and obligations of both parties where collection of the contract price is deemed probable.

The Company records revenue based on a

five

-step model which includes confirmation of contract existence, identifying the performance obligations, determining the transaction price, allocating the contract transaction price to the performance obligations, and recognizing the revenue when (or as) control of goods or services is transferred to the customer. The transfer of control

can occur at the time of delivery, installation or post-installation where applicable. 

The Company's equipment and system product line includes certain contracts which do

not

meet the requirements of an exchange transaction and therefore do

not

fall within the scope of ASC

606.

  As these non-exchange transaction contracts are considered grant revenue and do

not

fall within any specific accounting literature, the Company follows guidance within ASC

606

by analogy to recognize grant revenue over time. 

For certain arrangements, such as contracts to perform research and development, prototype development contracts and certain customized product sales, the Company records revenues using the over-time method, measured by the relationship of costs incurred to total estimated contract costs. Over-time revenue recognition accounting is predominantly used on certain turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government. The Company follows this method when any of the

three

following criteria are met: when the customer receives the benefits as they are performed, control transfers to the customer as the work is performed, or there is

no

alternative use to the Company and there is an enforceable right to payment through the life of the contract. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. For contracts where reasonably dependable estimates of the revenues and costs cannot be made, the Company follows the point in time method.

The Company enters into sales arrangements that

may

provide for multiple performance obligations to a customer. Sales of certain products

may

include extended warranty and support or service packages, and at times include performance bonds. As these contracts progress, the Company continually assesses the probability of a payout from the performance bond. Should the Company determine that such a payout is likely; the Company would record a liability. The Company would reduce revenue to the extent a liability is recorded. In addition, the Company enters into licensing arrangements that include training services.

Performance obligations are separated into more than

one

unit of accounting when (

1

) the delivered element(s) have value to the customer on a stand-alone basis, and (

2

) the Company's promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract.  In general, revenues are separated between the different product shipments which have stand-alone value, and the various services to be provided. Revenue for product shipments is generally recognized at a point in time where control of the product is transferred to the customer, while revenues for the services are generally recognized over the period of performance. The Company identifies all goods and/or services that are to be delivered separately under a sales arrangement and

allocates the transaction price to each distinct performance obligation using the respective standalone selling price ("SSP") which is determined primarily using the cost plus expected margin approach for products and a relief from royalty method for licenses.  Revenue allocated to each performance obligation is recognized when, or as, the performance obligation is satisfied. 

The Company reviews SSP and the related margins at least annually.

The Company’s license agreements provide either for the payment of contractually determined paid-up front license fees or milestone based payments in consideration for the grant of rights to manufacture and or sell products using its patented technologies or know-how. Some of these agreements provide for the release of the licensee from past and future intellectual property infringement claims. When the Company can determine that it has

no

further obligations other than the grant of the license and that the Company has fully transferred the technology know-how, the Company recognizes the revenue under a point in time model. In other license arrangements, the Company

may

also agree to provide training services to transfer the technology know-how.  In these arrangements, the Company has determined that the licenses have

no

standalone value to the customer and are

not

separable from training services as the Company can only fully transfer the technology know-how through the training component. Accordingly, the Company accounts for these arrangements as a single unit of accounting, and recognizes revenue over the period of its performance using the over-time method. Costs for these arrangements are expensed as incurred.

Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability of any portion of the contract value is

not

probable, an analysis of variable consideration will be performed using either the most likely amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability has been resolved. For contractual arrangements that involve variable consideration, the Company recognizes revenue for these amounts upon reaching the constraining event successfully.  The Company does

not

generally provide for extended payment terms or provide its customers with a right of return.

The Company has elected to record taxes collected from customers on a net basis and does

not

include tax amounts in revenue or costs of revenue.

The Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances.

Standard Product Warranty, Policy [Policy Text Block]

Product Warranty

Warranty obligations are incurred in connection with the sale of the Company’s products.  The Company provides assurance-type warranties on all product sales for a term of typically 

one

 to 

three

years, and extended service-type warranties at the customers’ option for an additional term ranging up to 

four

 additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the service.  The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates and related costs to repair given products. The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the estimated warranty liability would be required.

Research and Development Expense, Policy [Policy Text Block]

Research and Development Costs

Research and development costs are expensed as incurred.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company’s provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carry-forwards using expected tax rates in effect in the years during which the differences are expected to reverse.

Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each fiscal year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. The Company has provided a valuation allowance against its U.S. and China deferred income tax assets since the Company believes that it is more likely than

not

that these deferred tax assets are

not

currently realizable due to uncertainty around profitability in the future.

Accounting for income taxes requires a

two

-step approach to recognizing and measuring uncertain tax positions. The

first

step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than

not

that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The

second

step is to measure the tax benefit as the largest amount that is more than

50%

likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but

not

limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company includes interest and penalties related to gross unrecognized tax benefits within the provision for income taxes.  See Note

13,

“Income Taxes,” for further information regarding its income tax assumptions and expenses.

Share-based Payment Arrangement [Policy Text Block]

Stock-Based Compensation

The Company accounts for stock-based payment transactions using a fair value-based method and recognizes the related expense in the results of operations.

Stock-based compensation is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period of the award. The fair value of restricted stock awards is determined by reference to the fair market value of the Company’s common stock on the date of grant. The Company uses the Black-Scholes option pricing model to estimate the fair value of awards with service and performance conditions. For awards with service conditions only, the Company recognizes compensation cost on a straight-line basis over the requisite service/vesting period. For awards with performance conditions, accruals of compensation cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatilities of the Company’s common stock and expected terms. The expected volatility rates are estimated based on historical and implied volatilities of the Company’s common stock. The expected term represents the average time that the options that vest are expected to be outstanding based on the vesting provisions and the Company’s historical exercise, cancellation and expiration patterns.

The Company estimates pre-vesting forfeitures when recognizing compensation expense based on historical and forward-looking factors. Changes in estimated forfeiture rates and differences between estimated forfeiture rates and actual experience

may

result in significant, unanticipated increases or decreases in stock-based compensation expense from period to period. The termination of employment of certain employees who hold large numbers of stock-based awards

may

also have a significant, unanticipated impact on forfeiture experience and, therefore, on stock-based compensation expense. The Company will update these assumptions on at least an annual basis and on an interim basis if significant changes to the assumptions are warranted.

The Company accounts 

for share-based payments made to non-employees 

in the same manner as other share-based payments for employees, with the measurement being based on the fair value at the grant date.   The non-employee share based payments will be included within the Company's stock compensation currently reported.

Earnings Per Share, Policy [Policy Text Block]

Computation of Net Income (Loss) per Common Share

Basic net income (loss) per share (“EPS”) is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing the net loss by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. For the fiscal years ended 

March 31, 2020

and

2019

, common equivalent shares of

354,748,

and

907,988,

respectively, were

not

included in the calculation of diluted EPS as they were considered antidilutive. The following table

reconciles

the numerators and denominators of the EPS calculation for the fiscal years ended

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation

The functional currency of all the Company’s foreign subsidiaries is the U.S. dollar, except for AMSC Austria, for which the local currency (Euro) is the functional currency, and AMSC China, for which the local currency (Renminbi) is the functional currency. The assets and liabilities of AMSC Austria and AMSC China are translated into U.S. dollars at the exchange rate in effect at the balance sheet date and income and expense items are translated at average rates for the period. Cumulative translation adjustments are excluded from net loss (income) and shown as a separate component of stockholders’ equity. Net foreign currency gains and losses are included in other income (expense), net on the consolidated statements of operations and were $

0.1

 million and

$1.6

million, for the fiscal years ended 

March 31, 2020

and

2019

, respectively. The Company has

no

restrictions on the foreign exchange activities of its foreign subsidiaries, including the payment of dividends and other distributions.

Risks and Uncertainties [Policy Text Block]

Risks and Uncertainties

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates and would impact future results of operations and cash flows.

The Company invests its available cash in high credit, quality financial instruments and invests primarily in investment-grade marketable securities, including, but

not

limited to, government obligations, money market funds and corporate debt instruments.

Several of the Company’s government contracts are being funded incrementally, and as such, are subject to the future authorization, appropriation, and availability of government funding. The Company has a history of successfully obtaining financing under incrementally-funded contracts with the U.S. government and it expects to continue to obtain additional contract modifications in the year ending

March 

31,

2021

 and beyond as incremental funding is authorized and appropriated by the government.

Commitments and Contingencies, Policy [Policy Text Block]

Contingencies

From time to time, the Company

may

be involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. Management reviews these estimates in each accounting period as additional information is known and adjusts the loss provision when appropriate. If the loss is

not

probable or cannot be reasonably estimated, a liability is

not

recorded in the consolidated financial statements. If, with respect to a matter, it is

not

both probable to result in liability and the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss is disclosed unless such an estimate cannot be made. The Company does

not

recognize gain contingencies until they are realized. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note

16,

“Commitments and Contingencies,” for further information.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Disclosure of Fair Value of Financial Instruments

The Company’s financial instruments consist principally of cash and cash equivalents, accounts receivable, marketable securities, accounts payable, accrued expenses, warrants to purchase shares of common stock, and derivatives. The carrying amounts of cash and cash equivalents, accounts receivable, short-term debt, accounts payable, and accrued expenses due to their short nature approximate fair value at 

March 31, 2020

and

2019

. The estimated fair values have been determined through information obtained from market sources and management estimates.  Marketable securities consist of certificates of deposit with maturities of greater than

12

months that are measured using such inputs as quoted prices and are classified within Level

1

of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value are recorded to other income (expense), net. The fair value for the warrant arrangements was historically estimated by management based on various assumptions in a lattice model and was subject to revaluation at each balance sheet date.  The Company classifies the estimates used to fair value these instruments as Level

3

inputs. See Note

5,

“Fair Value Measurements” for a full discussion on fair value measurements.

Fair Value Disclosures [Text Block]

5.

Fair Value Measurements

A valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into

three

broad levels as follows:

Level  1	-	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level  2	-	Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level  3	-	Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

The Company provides a gross presentation of activity within Level

3

measurement roll-forward and details of transfers in and out of Level

1

and

2

measurements.  A change in the hierarchy of an investment from its current level is reflected in the period during which the pricing methodology of such investment changes.  Disclosure of the transfer of securities from Level

1

to Level

2

or Level

3

is made in the event that the related security is significant to total cash and investments.  The Company did

not

have any transfers of assets and liabilities from Level

1,

Level

2

or Level

3

of the fair value measurement hierarchy during the year ended

March 31, 2020

.

A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Valuation Techniques

Cash Equivalents

Cash equivalents consist of highly liquid instruments with maturities of

three

months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level

1

of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist of certificates of deposit with maturities of greater than

12

months that are measured using such inputs as quoted prices and are classified within Level

1

of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date.  All marketable securities are considered available for sale and are carried at fair value.   Changes in fair value would be recorded to other income (expense), net.  The Company recognized

$0.1

million in unrealized gains on marketable securities, which is recorded in other income, for the fiscal year ending

March 31, 2020

and did

not

recognize any gains or losses on marketable securities in the fiscal year ended

March 31, 2019.  

The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security.  If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Warrants

The Company issued warrants in conjunction with an equity offering to Hudson Bay Capital in

November 2014

and a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules”). The warrants issued to Hercules were exercised on

April 8, 2019. 

The warrants issued to Hudson were partially exercised on

November 13, 2019

and the remaining unexercised warrants expired on

November 13, 2019. 

As of 

March 31, 2020

the Company has

remaining outstanding warrants.

The Company historically relied on various assumptions in a lattice model to determine the fair value of warrants. The Company had valued the warrants within Level

3

of the valuation hierarchy. See Note

12,

“Warrants and Derivative Liabilities,” for a discussion of the warrants and the valuation assumptions used.

             On

March 27, 2020,

the United States enacted the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The Cares Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effect of COVID-

19.

While the CARES Act provides sweeping tax changes in response to the COVID-

19

pandemic, some of the more significant provisions include removal of certain limitations on utilization of net operating losses, increasing the loss carryback period for certain losses to

five

years, and increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act of

2017.

The CARES Act is

not

expected to have a material impact on the Company’s financial position, results of operations or cash flows.

The Company has provided a full valuation allowance against its net deferred income tax assets in the U.S. and China since it is more likely than

not

that its deferred tax assets will

not

be realizable. After consideration of all the available evidence, both positive and negative, the Company has determined that a

$200.0

million valuation allowance at

March 31, 2020

is necessary to reduce the deferred tax assets to the amount that will more likely than

not

be realized.

At

March 31, 2020

, the Company had aggregate net operating loss carryforwards in the U.S. for federal and state income tax purposes of approximately

$799.2

million and

$203.6

million, respectively, which expire in the years ending

March 

31,

2020

 through

2040.

For U.S. federal tax purpose, approximately

$54.0

million of Federal net operating losses have an indefinite carryforward period. Included in the U.S. net operating loss are

$3.7

million of acquired losses from Power Quality Systems, Inc. and

$0.3

million of acquired losses from Infinia Technology Corporation. Research and development and other tax credit carryforwards amounting to approximately

$10.1

million and

$3.5

million are available to offset federal and state income taxes, respectively, and will expire in the years ending

March 

31,

2020

 through

2040.

At

March 31, 2020

, the Company had aggregate net operating loss carryforwards for its Chinese operation of approximately

$56.0

million, which can be carried forward for

five

years and begin to expire

December 

31,

2020.

 

Section 

382

of the U.S. Internal Revenue Code of

1986,

as amended (the “IRC”), provides limits on the extent to which a corporation that has undergone an ownership change (as defined) can utilize any net operating loss ("NOL") and general business tax credit carryforwards it

may

have. The Company last updated its study for the acquisition of ITC.  The Company increased its NOL’s by

$0.3

million due to acquired losses in the fiscal year ended

March 31, 2018

from ITC. The Company conducted a study on the acquired NOL and concluded that the limitations under Section

382

will

not

have a material impact on its ability to utilize its NOL carryforwards.  If there were material ownership changes subsequent to the study, such changes could limit the Company's ability to utilize its NOL carryforwards.

The total amount of undistributed foreign earnings available to be repatriated at

March 31, 2020

was

$1.9

million resulting in the recording of a

$0.2

million deferred tax liability for foreign withholding taxes.

The Company has

not

recorded a deferred tax asset for the temporary difference associated with the excess of the tax greater than the book basis in its Chinese subsidiary as the future tax benefit is

not

expected to reverse in the foreseeable future.

Accounting for income taxes requires a

two

-step approach to recognizing and measuring uncertain tax positions. The

first

step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than

not

that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The

second

step is to measure the tax benefit as the largest amount that is more than

50%

likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but

not

limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision.  The Company did

not

identify any uncertain tax positions at

March 31, 2020

.  The Company did

not

have any gross unrecognized tax benefits at

March 31, 2020

or

2019

.

There were

no

reversals of uncertain tax positions in the fiscal years ended

March 31, 2020

and

2019

.

The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. Any unrecognized tax benefits, if recognized, would favorably affect its effective tax rate in any future period. The Company does

not

expect that the amounts of unrecognized benefits will change significantly within the next

twelve

months.

The Company conducts business globally and, as a result, its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. Major tax jurisdictions include the U.S., China, Romania and Austria. All U.S. income tax filings for fiscal years ended

March 

31,

1996

 through

2020

 remain open and subject to examination.

All fiscal years from the fiscal year ended

March 31, 2018 

through

2020

 remain open and subject to examination in Austria.  As of

March 31, 2020

, the Company remains open to audit for the calendar years

2015

and forward in China.  Tax filings in Romania for the fiscal years ended

March 31, 2016

through

2020

 remain open and subject to examination.
