Graham Corporation ("we," "us," "our" or the "Company") is a global business that designs, manufactures and sells critical equipment for the energy, defense and chemical/petrochemical industries. Our energy markets include oil refining, cogeneration, and alternative power. For the defense industry, our equipment is used in nuclear propulsion power systems for the U.S. Navy. For the chemical and petrochemical industries, our equipment is used in fertilizer, ethylene, methanol and downstream chemical facilities. Graham’s global brand is built upon our world-renowned engineering expertise in vacuum and heat transfer technology, responsive and flexible customer service and high quality standards. We design and manufacture custom-engineered ejectors, vacuum pumping systems, surface condensers and vacuum systems. Our equipment can also be found in other diverse applications such as metal refining, pulp and paper processing, water heating, refrigeration, desalination, food processing, pharmaceutical, heating, ventilating and air conditioning.

Our corporate headquarters are located in Batavia, New York. We have production facilities located with our headquarters in Batavia. We also have atwo wholly-owned foreign ~~subsidiary,~~subsidiaries, Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd. ("GVHTT"), located in Suzhou, ~~China.~~China, and Graham India Private Limited ("GIPL"), located in Ahmedabad, India. GVHTT provides sales and engineering support for us in the People’s Republic of China and management oversight throughout Southeast Asia. ~~In the fiscal quarter ended December 31, 2018, we established Graham India Private Limited ("GIPL") as a wholly-owned subsidiary.~~ GIPL ~~located in Ahmedabad, India,~~ serves as a sales and market development office focusing on the refining, petrochemical and fertilizer markets. During the fiscal year ended March 31, 2020, we sold our wholly-owned subsidiary, Energy Steel & Supply Co. ("Energy Steel"), located in Lapeer, Michigan.

On June 1, 2021, we acquired Barber-Nichols, Inc. ("BNI"), a privately-owned designer and manufacturer of turbomachinery products for the aerospace, cryogenic, defense and energy markets, located in Arvada, Colorado. BNI has approximately 140 employees. The acquisition includes BNI’s new, 43,000 square foot, state-of-the-art manufacturing plant which is part of their 96,000 square foot facility in Arvada, Colorado. We believe that this acquisition will further our growth strategy through market and product diversification, broaden our offerings to the defense and energy markets and strengthen our presence in the defense sector.

We were incorporated in Delaware in 1983 and are the successor to Graham Manufacturing Co., Inc., which was incorporated in New York in 1936. Our stock is traded on the NYSE under the ticker symbol "GHM".

Unless indicated otherwise, dollar figures in this Annual Report on Form 10-K are reported in thousands.

Due to the changes in the commercial nuclear utility industry over the last several years and the subsequent decline in performance of our wholly-owned subsidiary, Energy Steel & Supply Co. ("Energy Steel"), located in Lapeer, Michigan, we have decided the business is better suited for another partner and have elected to divest of it. We are in discussions to sell the business. Subsequent to March 31, 2019, we received an offer for the purchase of Energy Steel. During fiscal 2019, Energy Steel had $8,336 in net sales.

Our products are used in a wide range of industrial process applications, primarily in energy and defense markets, including:

Our principal customers include end users of our products in their manufacturing, refining and power generation processes, large engineering companies that build installations for companies in such industries, and the original equipment manufacturers who combine our products with their equipment prior to its sale to end users.

Our products are sold by a team of sales engineers whom we employ directly as well as by independent sales representatives located worldwide. There may be short periods of time, a fiscal year for example, where one customer may make up greater than 10% of our business. However, if this occurs in multiple years, it is usually not the same customer or project over such a multi-year period. ~~One customer did account~~Two customers each accounted for ~~greater~~more than 10% of our ~~business~~revenue in the fiscal ~~2019.~~ year ended March 31, 2021, which we refer to as fiscal 2021, while a different customer accounted for more than 10% of our revenue in the fiscal year ended March 31, 2020, which we refer to as fiscal 2020.

As a result of our diversification efforts to more extensively support the U.S. Navy, we have increased our domestic sales in ~~2019.~~2021. Over a business cycle in the energy markets, our domestic sales will generally range between 50% and ~~75%~~70% of total sales. The mix of domestic and international sales can vary from year to year.

Our backlog at March 31, ~~2019~~2021 was ~~$132,127~~$137,567 compared with ~~$117,946~~$112,389 at March 31, ~~2018. Excluding backlog associated with assets and liabilities held for sale, backlog on March 31, 2019 was $124,088.~~2020.

We intend to strategically leverage and deploy our assets, including but not limited to, financial, technical, manufacturing and industry know-how, in order to capture expanded market share within the geographies and industries we serve, expand revenue opportunities in adjacent and countercyclical markets and continually improve our results of operations in order to:

•Generate strong cash flow from ~~operations;~~operations to reinvest in our business or return to shareholders in the form of ordinary

To accomplish our objectives and maintain strategic focus, we believe that we must:

In order to effectively implement our strategy, we also believe that we must continue to invest in and leverage our unique ~~customer~~ value enhancing differentiators, including:

Our business is highly competitive. The principal bases on which we compete include technology, price, performance, reputation, delivery, and quality. Our competitors listed in alphabetical order by market include:

Our success depends in part on our ability to protect our proprietary technologies. We rely on a combination of patent, copyright, trademark, trade secret laws and contractual confidentiality provisions to establish and protect our proprietary rights. We also depend heavily on the brand recognition of the Graham name in the marketplace.

Historically, we have not been materially adversely impacted by the availability of raw materials.

Our business does not require us to carry significant amounts of inventory or materials beyond what is needed for work in process. We negotiate progress payments from our customers on our large projects to finance costs incurred. We do not provide rights to return goods, or payment terms to customers that we consider to be extended in the context of the industries we serve. We do provide for warranty claims.

We believe that we are in material compliance with applicable existing environmental laws and regulations. We do not anticipate that our compliance with federal, state and local laws regulating the discharge of material in the environment or otherwise pertaining to the protection of the environment will have a material adverse effect upon our capital expenditures, earnings or competitive position.

No material part of our business is seasonal in nature. However, our business is highly cyclical in nature as it depends on the willingness of our customers to invest in major capital projects.

During fiscal ~~2019,~~2021, and fiscal ~~2018~~2020, and the fiscal year ended March 31, ~~2017, which we refer to as "fiscal 2017",~~2019, we spent ~~$3,538, $3,211~~$3,367, $3,353 and ~~$3,863,~~$3,538, respectively, on research and development ~~activities related both~~("R&D") activities. The majority of our R&D is application specific to help solve our customers’ problems in order to improve efficiencies, address challenging environments or caustic materials, or redesign for form and function.

Our business and operations are subject to numerous risks, many of which are described below and elsewhere in this Annual Report on Form 10-K. If any of the events described below or elsewhere in this Annual Report on Form 10-K occur, our business and results of operations could be harmed. Additional risks and uncertainties that are not presently known to us, or which we currently deem to be immaterial, could also harm our business and results of operations.

Our business, financial condition and results of operations have been and may continue to be adversely affected by global public health pandemics, including the recent COVID-19 pandemic.

Our business, financial condition and results of operations have been and may continue to be adversely affected if the COVID-19 pandemic, or another global health crisis, impacts our employees, suppliers, customers, financing sources or others’ ability to conduct business or negatively affects consumer and business confidence or the global economy. The COVID-19 health crisis has affected large segments of the global economy, including the markets we operate in. The COVID-19 pandemic began affecting our business in the fourth quarter of fiscal 2020.

The pandemic and any additional preventative or protective actions that governments or we may take in response to the COVID-19 pandemic may have a material adverse effect on our business or our suppliers, distribution channels, and customers, including business shutdowns or disruptions for an indefinite period of time, reduced operations, restrictions on shipping, fabricating or installing products, reduced consumer demand or customers’ ability to make payments. We have and may continue to experience additional operating costs due to increased challenges with our workforce (including as a result of illness, absenteeism or government orders), implementing further precautionary measures to protect the health of our workforce, increased project cancellations or projects put on hold, access to supplies, capital, and fundamental support services (such as shipping and transportation). Any resulting financial impact cannot be fully estimated at this time, but may materially affect our business, financial condition or results of operations. The extent to which the COVID-19 pandemic affects our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions to contain the pandemic or treat its impact, among others.

Due to a potential COVID-19 reduction in throughput capacity, certain contracts in our backlog may experience delayed shipment. We accept contracts that contain provisions for a buyer to recover liquidated damages if our delivery is past contractual delivery dates, and such liquidated damages claimed by a customer could adversely affect financial performance. The impact of the COVID-19 pandemic may also exacerbate other risks discussed in this Item 1A - Risk Factors, any of which could have a material adverse effect on us. The situation surrounding the COVID-19 pandemic and its impact continues to change rapidly and additional impacts may arise that we are presently unaware of.

The COVID-19 pandemic may disrupt and cause delays in our supply chains, and such disruptions could adversely affect our results of operations and financial performance.

The raw materials that we source come from a wide variety of domestic and international suppliers. Global sourcing of many of the products we sell is an important factor in our financial results. It is possible that the ongoing COVID-19 pandemic could cause a disruption in our supply chain. If that supply chain is disrupted for an extended period of time, including due to the COVID-19 pandemic or another global health crisis, our ability to meet customer requirements and achieve our financial performance may be affected. We cannot at this time predict the impact of the COVID-19 pandemic on our supply chain, but we are maintaining ongoing communications with our suppliers to monitor their status. Any disruption to our supply chain could negatively impact our operations and financial performance.

Disruption to the global oil markets, including from the impact of the COVID-19 pandemic, could adversely affect our customers’ and our own results of operations and financial performance.

Our business, consolidated results of operations and financial condition, or that of our customers, may be adversely affected by significant decreases in demand for oil resulting from global restrictions on travel, work from home practices, and the significant reduction in industrial and commercial activity, or an increase in operating costs as a result of the global business disruption resulting from the COVID-19 pandemic or that may result from a future global health crisis. Global oil markets continue to experience significant volatility and had dramatic declines in prices in fiscal 2021 due to decreased demand during the COVID-19 pandemic resulting from government-led “stay-at-home” orders and social distancing initiatives and a geopolitical imbalance of supply. Demand for some of our products is dependent on the level of expenditures by our customers in the oil and gas industry. Accordingly, continued volatility or downturns in the oil markets, and potential project cancellations, could materially and adversely impact our financial condition or results of operations.

We operate and compete globally. The response to the COVID-19 pandemic by domestic and foreign governments has been and may continue to be varied and those differences may impact our competitiveness. Our operating subsidiaries are located in China and India, and those countries’ responses to the COVID-19 pandemic have varied from the United States’ response. There are uncertain political climates in the regions where our subsidiaries operate, and governmental action in those regions may result in the temporary closure or limited operations of our subsidiaries. Government assistance during a pandemic may also differ between private and public companies, which may provide an advantage to one compared with another. This may affect our competitive position and could disrupt the market access and success of our business compared with other current or new competitors. This impact could have a material adverse impact on our financial condition or results of operation.

COVID-19 disruption could impact our management team due to illness from the pandemic.

Our business has specialized management, technical and sales personnel who may become unavailable for an extended period or lost due to the effect of COVID-19 or another pandemic. The COVID-19 pandemic may significantly disrupt our workforce if a significant percentage of our employees are unable to work due to illness or quarantines. In addition, COVID-19-related illness could impact members of our Board of Directors, resulting in absenteeism from meetings of the directors or committees of directors, making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs. Any of the loss of personnel or disruption in management as described above could have a material adverse impact on our business and results of operations.

The markets we serve include the petroleum refining and petrochemical industries. These industries are both highly cyclical in nature and dependent on the prices of crude oil and natural gas as well as on the differential between the two prices. As a result, volatility in the prices of oil and natural gas may negatively impact our operating results.

A substantial portion of our revenue is derived from the sale of our products to companies in the chemical, petrochemical, and petroleum refining ~~and power generating~~ industries, or to firms that design and construct facilities for these industries. These industries are highly cyclical and have historically experienced severe downturns. The prices of crude oil and natural gas have historically had periods when they have been very volatile, as evidenced by the extreme volatility in oil prices over the past few ~~years.~~years and, in particular, volatility related to the COVID-19 pandemic. During times of significant volatility in the market for crude oil or natural gas, our customers often refrain from placing orders until the market stabilizes and future demand projections are clearer. If our customers refrain from placing orders with us, our revenue would decline and there could be a material adverse effect on our business and results of operations.

The ongoing slowdown in our energy and petrochemical markets that began during the latter part of fiscal 2020, and was caused primarily by an excess supply of crude oil, had a negative impact on commodity pricing which resulted in more measured investment in maintenance and capital projects within these markets. The economic slowdown and corresponding reductions in demand for transportation fuel and petrochemical products caused by the ongoing COVID-19 pandemic further adversely affected these markets. As a result of these combined adverse supply-side and demand-side disruptions, our commercial customers in these markets have significantly reduced their operating budgets for the types of products and services we provide. The timing and catalyst for a recovery in these markets remains uncertain. Accordingly, we believe that in the near term the quantity of projects available for us to compete for will be fewer and that the pricing environment will remain challenging.

We believe that over the long-term, demand for our products will expand in the petrochemical, petroleum refining and power generating industries. A sustained deterioration in any of the

industries we serve would materially harm our business and operating results because our customers would not likely have the resources necessary to purchase our products, nor would they likely have the need to build additional facilities or improve existing facilities. As we have seen in the recent past, a cyclical downturn can occur suddenly and result in extremely different financial performance sequentially from quarter to quarter or on an annual comparative basis due to an inability to rapidly adjust costs.

The relative costs of oil, natural gas, nuclear power, hydropower and numerous forms of alternative energy production may have a material adverse impact on our business and operating results.

Global and regional energy supply comes from many sources, including oil, natural gas, coal, hydro, nuclear, solar, wind, geothermal and biomass, among others. A cost or supply shift among these sources could negatively impact our business opportunities going forward and the profitability of those opportunities. A demand shift, where technological advances favor the utilization of one or a few sources of energy may also impact the demand for our products. If demand shifts in a manner that increases energy utilization outside of our traditional customer base or expertise, our business and financial results could be materially adversely affected. In addition, governmental policy can affect the relative importance of various forms of energy sources. For example, non-fossil based sources may ~~require and often~~ receive government tax incentives to foster investment. If these incentives become more prominent, our business and results of operations could suffer.

Our business is highly competitive. If we are unable to successfully implement our business strategy and compete against entities with greater resources than us or against competitors who have a relative cost advantage, we risk losing market share to current and future competitors.

~~We encounter intense competition in all~~A transition toward different types of our markets. Some of our present and potential competitors may have substantially greater financial, marketing, technical or manufacturing resources. Our competitors may also be able to respond more quickly to new technologies or processes and changes in customer demands and they may be able to devote greater resources towards the development, promotion and sale of their products. Certain of our competitors may also have a cost advantage compared to us due to their geography or changes in relative currency values and may compete against us based on price. This may affect our ability to secure new business and maintain our level of profitability. In addition, our current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties that increase their ability to address the needs of our customers. Moreover, customer buying patterns can change if customers become more price sensitive and accepting of lower cost suppliers. If we cannot compete successfully against current or future competitors, our business will be materially adversely affected.

A change in our end use customers, our markets, or a change in the engineering procurement and construction companies serving our markets could harm our business and negatively impact our financial results.

Although we have long-term relationships with many of our end use customers and with many engineering, procurement and construction companies, the project management requirements, pricing levels and costs to support each customer and customer type are often different. Our customers have historically focused on the quality of the engineering and product solutions which we have provided to them. As our markets continue to grow, and new market opportunities expand, we could see a shift in pricing as a result of facing competitors with lower production costs, whichenergy may have a material adverse impact on our ~~results of operations~~business and ~~financial~~operating results. ~~There has been more of a focus on relative importance of cost versus quality~~

Changes in consumer demand, including some driven by governmental and political preferences, toward electric, compressed natural gas, hydrogen vehicles and other alternative energy may impact our business. We have products which ~~looks at short-term costs instead of total long-term cost of operations. Our customers are unable to predict the length of the time period for the economic viability of their plants.~~

A significant change in ~~the structure of our markets; the relationships between engineering~~demand for oil and ~~procurement companies, original equipment suppliers, others in the supply chain and any of their relationships with the end users could harm our business and negatively impact our financial results.~~

There are strong and long-standing relationships throughout the supply chain between the many parties involved in serving the end user of our products. A change in the landscape between engineering and procurement companies, original equipment suppliers, others in the supply chain and/or with the end users couldgas based products may have a material adverse ~~effect on our business and results of operations. These changes might occur through acquisitions or other business partnerships and could have a material~~ impact on our ~~business and negatively impact our financial results.~~

~~The loss of, or significant reduction or delay in, purchases by our largest customers could reduce our revenue and adversely affect our results of operations.~~

A small number of customers has accounted for a substantial portion of our historical net sales. For example, sales to our top ten customers, who can vary each year, accounted for 41%, 41% and 38% of consolidated net sales in fiscal 2019, fiscal 2018 and fiscal 2017, respectively. We expect that a limited number of customers will continue to represent a substantial portion of our sales for

the foreseeable future. The loss of any of our major customers, a decrease or delay in orders or anticipated spending by such customers or a delay in the production of existing orders could materially adversely affect our revenues and results of operations.

~~We may experience customer concentration risk related to strategic growth for U.S. Navy projects.~~

We believe our strategy to increase the penetration of U.S. Navy related opportunities will lead to U.S. Navy related projects consistently being greater than 10% of our total revenue. While these projects are spread across multiple contractors for the U.S. Navy, the end customer for these projects is the same. This concentration of business could add additional risk to us should there be a disruption, short or long term, in the funding for these projects or our participation in the U.S. Navy Nuclear Propulsion program.

~~A large percentage of our sales occur outside of the U.S. As a result, we are subject to the economic, political, regulatory and other risks of international operations.~~

For fiscal 2019, 35% of our revenue was from customers located outside of the U.S. Moreover, through our subsidiaries, we maintain a sales office in China and a sales and market development office in India. We believe that revenue from the sale of our products outside the U.S. will continue to account for a significant portion of our total revenue for the foreseeable future. We intend to continue to expand our international operations to the extent that suitable opportunities become available. Our foreign operations and sales could be adversely affected as a result of:

The impact of potential changes in customs and trade policies and tariffs imposed by the U.S. and those imposed in response by other countries, including China, as well as rapidly changing trade relations, could materially and adversely affect our business and results of operations.

products more expensive. As a result, our products could become less attractive to customers outside the U.S. due to U.S. import tariffs on our raw materials and our profit margins would be negatively impacted. Accordingly, continued tariffs may weaken relationships with certain of our trading partners and may adversely affect our financial performance and results of operations. When beneficial to us, we may consider alternate sourcing options, including off shore subcontracting, in order to minimize the impact of the tariffs. Because we conduct aspects of our business in China through our subsidiary, potential reductions in trade with China and diminished relationships between China and the U.S., as well as the continued escalation of tariffs, could have a material adverse effect on our business and results of operations.

~~Global demand growth could be led by emerging markets, which could result in lower profit margins and increased competition.~~

The increase in global demand could be led by emerging markets. If this is the case, we may face increased competition from lower cost suppliers, which in turn could lead to lower profit margins on our products. Customers in emerging markets may also place less emphasis on our high quality and brand name than do customers in the U.S. and certain other industrialized countries where we compete. If we are forced to compete for business with customers that place less emphasis on quality and brand recognition than our current customers, our results of operations could be materially adversely affected.

Climate change and greenhouse gas regulations may affect our customers’ investment decisions.

Due to concern over the risk of climate change, a number of countries have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These restrictions may affect our customers' abilities and willingness to invest in new facilities or to re-invest in current operations. These requirements could impact the cost of our customers’ products, lengthen project implementation times, and reduce demand for hydrocarbons, as well as shift hydrocarbon demand toward lower-carbon sources. Any of the foregoing could adversely impact the demand for our products, which in turn could have an adverse effect on our business and results of operations.

We encounter intense competition in all of our markets. Some of our present and potential competitors may have substantially greater financial, marketing, technical or manufacturing resources. Our competitors may also be able to respond more quickly to new technologies or processes and changes in customer demands and they may be able to devote greater resources towards the development, promotion and sale of their products. Certain competitors may also have a cost advantage compared to us due to their geography or changes in relative currency values and may compete against us based on price. This may affect our ability to secure new business and maintain our level of profitability. As our markets continue to grow, and new market opportunities expand, we could see a shift in pricing as a result of facing competitors with lower production costs, which may have a material adverse impact on our results of operations and financial results. In addition, our current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties that increase their ability to address the needs of our customers. Moreover, customer buying patterns can change if customers become more price sensitive and accepting of lower cost suppliers. If we cannot compete successfully against current or future competitors, our business will be materially adversely affected.

Although we have long-term relationships with many of our end use customers and with many engineering, procurement and construction companies, the project management requirements, pricing levels and costs to support each customer and customer type are often different. Our customers have historically focused on the quality of the engineering and product solutions which we have provided to them. Because our customers are unable to predict the length of the time period for the economic viability of their plants, there has been more of a focus on relative importance of cost versus quality which looks at short-term costs instead of total long-term cost of operations.

A change in the structure of our markets; the relationships between engineering and procurement companies, original equipment suppliers, others in the supply chain and any of their relationships with the end users could harm our business and negatively impact our financial results.

There are strong and long-standing relationships throughout the supply chain between the many parties involved in serving the end user of our products. A change in the landscape between engineering and procurement companies, original equipment suppliers, others in the supply chain, including disruptions in the supply chain due to the COVID-19 pandemic, and/or with the end users could have a material adverse effect on our business and results of operations. These changes, or others, might occur through acquisitions or other business partnerships and could have a material impact on our business and negatively impact our financial results.

The loss of, or significant reduction or delay in, purchases by our largest customers could reduce our revenue and adversely affect our results of operations.

While we may have only one or two customers represent over 10% of revenue in any one year, a small number of customers have accounted for a substantial portion of our historical net sales. For example, sales to our top ten customers, who can vary each year, accounted for 63%, 48% and 41% of consolidated net sales in fiscal 2021, fiscal 2020 and fiscal 2019, respectively. We expect that a limited number of customers will continue to represent a substantial portion of our sales for the foreseeable future. The loss of any of our major customers, a decrease or delay in orders or anticipated spending by such customers, or a delay in the production of existing orders could materially adversely affect our revenues and results of operations.

The success of our acquisition strategy will depend, in part, on our ability to identify suitable companies or businesses to purchase and then successfully negotiate and close acquisition transactions. In addition, our success depends in part on our ability to integrate acquisitions and realize the anticipated benefits from combining the acquisition with our historical business, operations and management. We cannot provide any assurances that we will be able to complete any acquisitions and then successfully integrate the business and operations of those acquisitions without encountering difficulties, including unanticipated costs, issues or liabilities, difficulty in retaining customers and supplier or other relationships, failure to retain key employees, diversion of our management’s attention, failure to integrate information and accounting systems or establish and maintain proper internal control over financial reporting. Moreover, as part of the integration process, we must incorporate an acquisition’s existing business culture and compensation structure with our existing business. We also need to utilize key personnel who may be distracted from the core business. If we are not able to efficiently integrate an acquisition’s business and operations into our organization in a timely and efficient manner, or at all, the anticipated benefits of the acquisition may not be realized, or it may take longer to realize these benefits than we currently expect, either of which could have a material adverse effect on our business or results of operations.

If we fail to successfully integrate BNI’s operations, our financial condition and results of operations could be adversely affected.

On June 1, 2021, we entered into a stock purchase agreement to acquire BNI, a privately-owned designer and manufacturer of turbomachinery products for the aerospace, cryogenic, defense and energy markets, located in Arvada, Colorado, for approximately $70,000. We may not realize every intended benefit of the acquisition which could adversely impact our results of operations. There are many challenges associated with integrating an acquisition such as BNI, including those associated with the integration of operations, retention of key management and other employees with historically different cultures and priorities, the diversion of management’s attention from ongoing business concerns while addressing integration matters, retaining existing business and operational relationships including customers, suppliers and others, unanticipated issues in integrating information technology, communications and other systems, as well as unforeseen expenses associated with the integration. Further, our future results will suffer if we do not effectively manage the expanded scope of our operations as a result of our acquisition of BNI.

We may experience customer concentration risk related to strategic growth for U.S. Navy projects.

We believe our strategy to increase the penetration of U.S. Navy related opportunities may lead to U.S. Navy related projects consistently being greater than 10% of our total revenue. While these projects are spread across multiple contractors for the U.S. Navy, the end customer for these projects is the same. This concentration of business could add additional risk to us should there be a disruption, short or long term, in the funding for these projects or our participation in the U.S. Navy Nuclear Propulsion program.

The size of our contracts with the U.S. Navy may produce volatility over the short term financial results.

We believe our strategy to increase the penetration of U.S. Navy related opportunities, which are often much larger contracts than our commercial contracts, may impact our ability to effectively provide accurate investor guidance for our near term financial results. These contracts can, on occasion, be delayed before or during the revenue recognition cycle. If we are unable to reallocate the resources to other projects, we may see an increase in volatility in our near term financial results.

A significant percentage of our sales occur outside of the U.S. As a result, we are subject to the economic, political, regulatory and other risks of international operations.

For fiscal 2021, 46% of our revenue was from customers located outside of the U.S. Moreover, through our subsidiaries, we maintain a sales office in China and a sales and market development office in India. We believe that revenue from the sale of our products outside the U.S. will continue to account for a significant portion of our total revenue for the foreseeable future. We intend to continue to expand our international operations to the extent that suitable opportunities become available. Our foreign operations and sales could be adversely affected as a result of:

The U.S. government has made proposals that are intended to address trade imbalances, which include encouraging increased production in the United States. These proposals could result in increased customs duties and the renegotiation of some U.S. trade agreements. Changes in U.S. and foreign governments’ trade policies have resulted and may continue to result in tariffs on imports into, and exports from, the U.S. Over the past few years, the U.S. imposed tariffs on imports from several countries, including China, Canada, the European Union and Mexico. In response, China, Canada and the European Union have proposed or implemented their own tariffs on certain exports from the U.S. into those countries. Tariffs affecting our products and product components, including raw materials we use, particularly high-end steel and steel related products, may add significant costs to us and make our products more expensive. Potential future changes in trade policies could result in customers changing their behavior in project procurement, due to uncertainty related to timely execution and/or import and export restrictions. As a result, our products could become less attractive to customers outside the U.S. due to U.S. import tariffs on our raw materials and our profit margins would be negatively impacted. Accordingly, continued tariffs may weaken relationships with certain trading partners and may adversely affect our financial performance and results of operations. When beneficial to us, we may consider alternate sourcing options, including off shore subcontracting, in order to minimize the impact of the tariffs. Because we conduct aspects of our business in China through our subsidiary, potential reductions in trade with China and diminished relationships between China and the U.S., including as a result of the recent COVID-19 pandemic, as well as the continued escalation of tariffs, could have a material adverse effect on our business and results of operations.

Global demand growth could be led by emerging markets, which could result in lower profit margins and increased competition.

An increase in global demand could be led by emerging markets. If this is the case, we may face increased competition from lower cost suppliers, which in turn could lead to lower profit margins on our products. Customers in emerging markets may also place less emphasis on our high quality and brand name than do customers in the U.S. and certain other industrialized countries where we compete. If we are forced to compete for business with customers that place less emphasis on quality and brand recognition than our current customers, our results of operations could be materially adversely affected.

The operations of our Chinese subsidiary may be adversely affected by China’s evolving economic, political and social conditions.

We conduct our business in China primarily through our wholly-owned Chinese subsidiary. The results of operations and future prospects of our Chinese subsidiary may be adversely affected by, among other things, changes in China's political, economic and social conditions, including as a result of the COVID-19 pandemic, changes in the relationship between China and its western trade partners, changes in policies of the Chinese government, changes in laws and regulations or in the interpretation of existing laws and regulations, changes in foreign exchange regulations, measures that may be introduced to control inflation, such as interest rate increases and changes in the rates or methods of taxation. In addition, changes in demand could result from increased competition from local Chinese manufacturers who have cost advantages or who may be preferred suppliers for Chinese end users. Also, Chinese commercial laws, regulations and interpretations applicable to non-Chinese owned market participants, such as us, are continually changing. These laws, regulations and interpretations could impose restrictions on our ownership or the operation of our interests in China and have a material adverse effect on our business and results of operations.

Intellectual property rights are difficult to enforce in China and India, which could harm our business.

Chinese commercial law is relatively undeveloped compared with the commercial law in many of our other major markets and limited protection of intellectual property is available in China as a practical matter. Similarly, proprietary information may not be afforded the same protection in India as it is in our other major markets with more comprehensive intellectual property laws. Although we take precautions in the operations of our subsidiaries to protect our intellectual property, any local design or manufacture

of products that we undertake could subject us to an increased risk that unauthorized parties will be able to copy or otherwise obtain or use our intellectual property, which could harm our business. We may also have limited legal recourse in the event we encounter patent or trademark infringers, which could have a material adverse effect on our business and results of operations.

Uncertainties with respect to the Chinese legal system may adversely affect the operations of our Chinese subsidiary.

Our Chinese subsidiary is subject to laws and regulations applicable to foreign investment in China. There are uncertainties regarding the interpretation and enforcement of laws, rules and policies in China. The Chinese legal system is based on written statutes, and prior court decisions have limited precedential value. Because many laws and regulations are relatively new and the Chinese legal system is still evolving, the interpretations of many laws, regulations and rules are not always uniform. Moreover, the relative inexperience of China's judiciary in many cases creates additional uncertainty as to the outcome of any litigation, and the interpretation of statutes and regulations may be subject to government policies reflecting domestic political agendas. Finally, enforcement of existing laws or contracts based on existing law may be uncertain and sporadic. For the preceding reasons, it may be difficult for us to obtain timely or equitable enforcement of laws ostensibly designed to protect companies like ours, which could have a material adverse effect on our business and results of operations.

Regulation of foreign investment in India may adversely affect the operations of our Indian subsidiary.

Our subsidiary in India is subject to laws and regulations applicable to foreign investment in India. India regulates ownership of Indian companies by foreign entities. These regulations may apply to our funding of our Indian operating subsidiary. For example, the government of India has set out criteria for foreign investments in India, including requirements with respect to downstream investments by Indian companies owned or controlled by foreign entities and the transfer of ownership or control of Indian companies in certain industries. These requirements may adversely affect our ability to operate our Indian subsidiary. There can be no assurance that we will be able to obtain any required approvals for future acquisitions, investments or operations in India, or that we will be able to obtain such approvals on satisfactory terms.

Changes in U.S. and foreign energy policy regulations could adversely affect our business.

Energy policy in the U.S. and in the other countries where we sell our products is evolving rapidly and we anticipate that energy policy will continue to be an important legislative priority in the jurisdictions where we sell our products. It is difficult, if not impossible, to predict the changes in energy policy that could occur, as they may be related to changes in political administration, public policy or other factors. The elimination of, or a change in, any of the current rules and regulations in any of our markets could create a regulatory environment that makes our end users less likely to purchase our products, which could have a material adverse effect on our business. Government subsidies or taxes, which favor or disfavor certain energy sources compared with others, could have a material adverse effect on our business and operating results.

Efforts to reduce large U.S. federal budget deficits could result in government cutbacks or shifts in focus in defense spending or in reduced incentives to pursue alternative energy projects, resulting in reduced demand for our products, which could harm our business and results of operations.

Our business strategy calls for us to continue to pursue defense-related projects as well as projects for end users in the alternative energy markets in the U.S. In recent years, the U.S. federal government has incurred large budget deficits. In the event that U.S. federal government defense spending is reduced or alternative energy related incentives are reduced or eliminated in an effort to reduce federal budget deficits, projects related to defense or alternative energy may become less plentiful. The impact of such reductions could have a material adverse effect on our business and results of operations, as well as our growth opportunities.

U.S. Navy orders are subject to annual government funding. A disruption in funding could adversely impact our business.

One of our growth strategies is to increase our penetration of U.S. Navy-related opportunities. Projects for the U.S. Navy and its contractors generally have a much longer order-to-shipment time period than our commercial orders. The time between the awarding of an order to ~~complete~~the completion of shipment can take three to seven years. Annual government funding is required to continue the production of this equipment. Disruption of government funding, short or long term, could impact the ability for us to continue our production activity on these orders. For example, the emergency spending bills related to the COVID-19 pandemic could compound the uncertainty already present in government funded programs. Since this business is expected to increase as a percentage of our overall business, such a disruption, should it occur, could adversely impact the sales and profitability of our business.

Changes in the competitive environment for U.S. Navy procurement could adversely impact our ability to grow this portion of our business.

Over the past few years, we have expanded our business and the opportunities where we bid related to U.S. Navy projects. This has increased our market share and caused an adverse share position for some of our competitors for these products. Competitor response to our market penetration is possible. Our customers may also raise concerns about their supplier concentration issues and the risk exposure related to this concentration. As the U.S. Navy is looking to expand its fleet, there is also a risk that their facilities,

their supply chain or our supply chain for raw materials, may not be able to support this expansion. This could adversely impact our ability to grow this portion of our business.

Contract liabilities for large U.S. Navy contracts may be beyond our normal insurance coverage and a claim could have an adverse impact on our financial results.

We are diligent at managing ongoing risks related to projects and the requirements of our customers. Our history at managing risk provides significant evidence that our exposure and risk isare minimal. In addition, we secure business insurance coverage to minimize the impact of a major failure or liability related to our customers. Due to certain U.S. government procurement policies, we may take on the risk of a liability for large U.S. Navy projects in excess of our insurance coverage and at a level which is higher than our commercial projects. A claim related to one of these projects could have an adverse impact on our financial results.

New technology used by the ships for the U.S. Navy may delay projects and may impact our ability to grow this portion of our business.

Certain U.S. Navy vessels are implementing new technologies, unrelated to any of the equipment that we provide. If there is a complication or delay to any ship caused by this new technology, it may delay the procurement and fabrication of future vessels, which could have a negative impact on our business.

~~Any future lapse~~Lapses in U.S. government appropriations ~~may~~have occurred, and any future lapses could disrupt U.S. export processing and related procedures and, as a result, may materially and adversely affect our revenue, results of operations and business.

The ~~impact of the lapse~~U.S. has previously experienced lapses in ~~U.S.~~ federal appropriations, which ~~commenced on December 22, 2018~~ had, in the past, a short-term effect on our business. Any such future lapse (each, a "Government Shutdown") could negatively affect our ability to ship finished products to customers. We rely on federal government personnel, who are not able to perform their duties during a Government Shutdown, to conduct routine business processes related to the inspection and delivery of our products, process export licenses for us and perform other services for us that, when disrupted, may prevent us from timely shipping products outside the U.S. If we are unable to timely ship our products outside the U.S., there could be a material adverse impact on our results of operations and business. Moreover, our inability to ship products, or the perception by customers that we might not be able to timely ship our products in the future, may cause such customers to look to foreign competitors to fulfill their demand. If our customers look to foreign competitors to source equipment of the type we manufacture, there could be a material adverse impact on our results of operations and business.

Near-term income statement impact from competitive contracts could adversely affect our operating results.

During weaker market periods, we may choose to be more aggressive in pricing certain competitive projects to protect or gain market share or to increase the utilization of our facilities. In these situations, it is possible that an incrementally profitable order, while increasing contribution, may be unprofitable from an accounting perspective when including fixed manufacturing costs. In these situations, we are required to recognize the financial loss at the time of order acceptance, or as soon as our cost estimates are updated, whichever occurs first. It is possible we may accumulate losses either on a large project or more than one project such that, in a short time period, for example, a reporting quarter, these losses may have a meaningful impact on the earnings of the period.

Our operating results could be adversely affected by customer contract cancellations and delays.

Adverse economic or specific project conditions can lead to a project being placed on hold or cancelled by our customers. While in fiscal 2021 we had no projects cancelled, in fiscal 2020 we had two projects cancelled. Similarly, while at March 31, 2021 we had no projects on hold, at March 31, 2020 we had two projects on hold. We attempt to mitigate the risk of cancellation by structuring contracts with our customers to maximize the likelihood that progress payments made to us for individual projects cover the costs we have incurred. As a result, we do not believe we have a significant cash exposure to projects which may be cancelled. Open orders are reviewed continuously through communications with customers. If it becomes evident to us that a project is delayed well beyond its original shipment date, management will move the project into "placed on hold" (i.e., suspended) category. Furthermore, if a project is cancelled by our customer, it is removed from our backlog.

The value of our backlog as of March 31, ~~2019~~2021 was ~~$132,127.~~$137,567. Our backlog can be significantly affected by the timing of large orders. The amount of our backlog at March 31, ~~2019~~2021 is not necessarily indicative of future backlog levels or the rate at which our backlog will be recognized as sales. Although historically the amount of modifications and terminations of our orders has not been material compared with our total contract volume, customers can, and sometimes do, terminate or modify their orders. This generally occurs more often in times of end market or capital market turmoil. ~~As evidence of this, we had orders totaling $24,361 cancelled during the downturn between fiscal 2015 through fiscal 2017, but have had no cancellations in fiscal years 2018 and 2019.~~ We cannot predict whether cancellations will occur or accelerate in the ~~future.~~future, and the ongoing COVID-19 pandemic may increase the risk of such cancellations. Although certain of our contracts in backlog may contain provisions allowing for us to assess cancellation charges to our customers to compensate us for costs incurred on cancelled contracts, cancellations of purchase orders or modifications made to existing contracts could substantially and materially reduce our backlog and, consequently, our future sales and results of operations. Moreover, delay of contract execution by our customers can result in volatility in our operating results.

Our current backlog contains a number of large orders from the U.S. Navy. In addition, we are continuing to pursue business in this end market which offers large multi-year projects which have an added risk profile beyond that of our historic customer base. A delay, long-term extension or cancellation of any of these projects could have a material adverse effect on our business and results of operations.

Further, certain defense contracts we secure may be designated a program of highest national priority requiring production preference over commercial orders which could impact our commercial backlog and result in production delays. As a result, commercial customers could seek damages, including liquidated damages, as performance penalties and there may be a negative impact to the willingness of customers to place future orders with us due to a concern that orders may be subordinated to such contracts.

An extended downturn could adversely impact the financial stability of our customers and increase the risk of uncollectable accounts receivables.

Our customers participate in cyclical markets, such as petroleum refining, ~~petrochemical~~petrochemicals and alternate energy. The financial strength of our customers can be impacted by a severe or lengthy downturn in these ~~markets.~~markets, including any downturn related to the COVID-19 pandemic. This could lead to additional risk in our ability to collect outstanding accounts receivables. We attempt to mitigate this risk with the utilization of progress payments for many projects, but certain industries, end markets and geographies are not as willing to make progress payments. Certain projects require a small portion of the total payments to be held until the customer's facility is fully operational, which can be in excess of one year beyond our delivery of equipment to them. This additional time may add risk to our ability to collect on the outstanding accounts receivables.

Our exposure to fixed-price contracts and the timely completion of such contracts could negatively impact our results of operations.

A substantial portion of our sales is derived from fixed-price contracts, which may involve long-term fixed price commitments by us to our customers. While we believe our contract management processes are strong, we nevertheless could experience difficulties in executing large contracts, including but not limited to, estimating errors, cost overruns, supplier failures and customer disputes. To the extent that any of our fixed-price contracts are delayed, our subcontractors fail to perform, contract counterparties successfully assert claims against us, the original cost estimates in these or other contracts prove to be inaccurate or the contracts do not permit us to pass increased costs on to our customers, our profitability may decrease or losses may be incurred which, in turn, could have a material adverse effect on our business and results of operations. For our U.S. Navy projects, these fixed priced contracts have order to shipment periods which can exceed five years. This additional time-based risk, which we believe is manageable, nevertheless increases the likelihood of cost fluctuation, which could have a material adverse effect on our business and results of operation.

Given our size and specialization of our business, if we lose any member of our management team and we experience difficulty in finding a qualified replacement, our business could be harmed.

Competition for qualified management and key technical and sales personnel in our industry is intense. Moreover, our technology is highly specialized, and it may be difficult to replace the loss of any of our key technical and sales personnel. Many of the companies with which we compete for management and key technical and sales personnel have greater financial and other resources than we do or are located in geographic areas which may be considered by some to be more desirable places to live. If we are not able to retain any of our key management, technical or sales personnel, it could have a material adverse effect on our business and results of operations.

During certain high demand periods, there can be a shortage of skilled production workers, especially those with high-end welding capabilities. We could experience difficulty hiring or replacing those individuals, which could adversely affect our business.

Our fabrication processes require highly skilled production workers, especially welders. Welding has not been an educational field that has been popular over the past few decades as manufacturing has moved overseas. While we have an in-house weld training program, if we are unable to retain, hire or train an adequate number of individuals with high-end welding capability, this could adversely impact our ability to achieve our financial objectives. In addition, if demand for highly skilled production workers were to significantly outstrip supply, wages for these skilled workers could dramatically increase in our and related industries and that could affect our financial performance. Furthermore, should we not be able to expand our production workforce, we would expect to increase the amount of outsourced fabrication which is likely to result in higher costs and lower margins.

~~Our acquisition strategy may not be successful or may increase business risk.~~

If we become subject to product liability, warranty or other claims, our results of operations and financial condition could be adversely affected.

The manufacture and sale of our products exposes us to potential product liability claims, including those that may arise from failure to meet product specifications, misuse or malfunction of our products, design flaws in our products, or use of our products with systems not manufactured or sold by us. For example, our equipment is installed in facilities that operate dangerous processes and the

misapplication, improper installation or failure of our equipment may result in exposure to potentially hazardous substances, personal injury or property damage.

Provisions contained in our contracts with customers that attempt to limit our damages may not be enforceable or may fail to protect us from liability for damages and we may not negotiate such contractual limitations of liability in certain circumstances. Our insurance may not cover all liabilities and our historical experience may not reflect liabilities we may face in the future. Our risk of liability may increase as we manufacture more complex or larger projects. We also may not be able to continue to maintain such insurance at a reasonable cost or on reasonable terms, or at all. Any material liability not covered by provisions in our contracts or by insurance could have a material adverse effect on our business and financial condition.

Furthermore, if a customer suffers damage as a result of an event related to one of our products, even if we are not at fault, they may reduce their business with us. We may also incur significant warranty claims which are not covered by insurance. In the event a customer ceases doing business with us as a result of a product malfunction or defect, perceived or actual, or if we incur significant warranty costs in the future, there could be a material adverse effect on our business and results of operations.

If third parties infringe upon our intellectual property or if we were to infringe upon the intellectual property of third parties, we may expend significant resources enforcing or defending our rights or suffer competitive injury.

Our success depends in part on our proprietary technology. We rely on a combination of patent, copyright, trademark, trade secret laws and confidentiality provisions to establish and protect our proprietary rights. If we fail to successfully enforce our intellectual property rights, our competitive position could suffer. We may also be required to spend significant resources to monitor and police our intellectual property rights. Similarly, if we were found to have infringed upon the intellectual property rights of others, our competitive position could suffer. Furthermore, other companies may develop technologies that are similar or superior to our technologies, duplicate or reverse engineer our technologies or design around our proprietary technologies. Any of the foregoing could have a material adverse effect on our business and results of operations.

In some instances, litigation may be necessary to enforce our intellectual property rights and protect our proprietary information, or to defend against claims by third parties that our products infringe upon their intellectual property rights. Any litigation or claims brought by or against us, whether with or without merit, could result in substantial costs to us and divert the attention of our management, which could materially harm our business and results of operations. In addition, any intellectual property litigation or claims against us could result in the loss or compromise of our intellectual property and proprietary rights, subject us to significant liabilities, require us to seek licenses on unfavorable terms, prevent us from manufacturing or selling certain products or require us to redesign certain products, any of which could have a material adverse effect on our business and results of operations.

We are subject to foreign currency fluctuations which may adversely affect our operating results.

We are exposed to the risk of currency fluctuations between the U.S. dollar and the currencies of the countries in which we sell our products to the extent that such sales are not based on U.S. ~~dollars.~~dollars, and volatility in foreign currency exchange rates has generally increased in connection with the COVID-19 pandemic. Currency movements can affect sales in several ways, the foremost being our ability to compete for orders against foreign competitors that base their prices on relatively weaker currencies. Strength of the U.S. dollar compared with the Euro or Asian currencies may put us in a less competitive position. At the outset of the COVID-19 pandemic, the U.S. dollar saw relative strengthening in relation to the Euro and Asian currencies, however, as the pandemic has continued, the relative strength of the U.S. dollar has increased in volatility. Business lost due to competition for orders against competitors using a relatively weaker currency cannot be quantified. In addition, cash can be adversely impacted by the conversion of sales made by us in a foreign currency to U.S. dollars. While we may enter into currency exchange rate hedges from time to time to mitigate these types of fluctuations, we cannot remove all fluctuations or hedge all exposures and our earnings are impacted by changes in currency exchange rates. In addition, if the counter-parties to such exchange contracts do not fulfill their obligations to deliver the contractual foreign currencies, we could be at risk for fluctuations, if any, required to settle the obligation. Any of the foregoing could adversely affect our business and results of operations. At March 31, ~~2019,~~2021, we held no forward foreign currency exchange contracts.

Security threats and other sophisticated computer intrusions could harm our information systems, which in turn could harm our business and financial results.

We utilize information systems and computer technology throughout our business. We store sensitive data, proprietary information and perform engineering designs and calculations on these systems. Threats to these systems, and the laws and regulations governing security of data, including personal data, on information systems and otherwise held by companies is evolving and adding layers of complexity in the form of new requirements and increasing costs of attempting to protect information systems and data and complying with new cybersecurity regulations. Information systems are subject to numerous and evolving cybersecurity threats and sophisticated computer crimes, which pose a risk to the stability and security of our information systems, computer technology, and business. Global cybersecurity threats can range from uncoordinated individual attempts to gain unauthorized access to our information systems and computer technology to sophisticated and targeted measures known as advanced persistent threats.

The techniques used in these attacks change frequently and may be difficult to detect for periods of time and we may face difficulties in anticipating and implementing adequate preventative measures. A failure or breach in security could expose our company as well as our customers and suppliers to risks of misuse of information, compromising confidential information and technology, destruction of data, production disruptions and other business risks which could damage our reputation, competitive position and financial results of

our operations. Further, our technology resources may be strained due to the increase in the number of remote users in response to the COVID-19 pandemic. In addition, defending ourselves against these threats may increase costs or slow operational efficiencies of our business. If any of the foregoing were to occur, it could have a material adverse effect on our business and results of operations.

We face potential liability from asbestos exposure and similar claims that could result in substantial costs to us as well as divert attention of our management, which could have a material adverse effect on our business and results of operations.

We are a defendant in a number of lawsuits alleging illnesses from exposure to asbestos or asbestos-containing products and seeking unspecified compensatory and punitive damages. We cannot predict with certainty the outcome of these lawsuits or whether we could become subject to any similar, related or additional lawsuits in the future. In addition, because some of our products are used in systems that handle toxic or hazardous substances, any failure or alleged failure of our products in the future could result in litigation against us. For example, a claim could be made under various regulations for the adverse consequences of environmental contamination. Any litigation brought against us, whether with or without merit, could result in substantial costs to us as well as divert the attention of our management, which could have a material adverse effect on our business and results of operations.

Many of our large international customers are nationalized or state-owned businesses. Any failure to comply with the United States Foreign Corrupt Practices Act could adversely impact our competitive position and subject us to penalties and other adverse consequences, which could harm our business and results of operations.

We are subject to the United States Foreign Corrupt Practices Act, which generally prohibits U.S. companies from engaging in bribery or making other prohibited payments to foreign officials for the purpose of obtaining or retaining business. Many foreign companies, including some of our competitors, are not subject to these prohibitions. Corruption, extortion, bribery, pay-offs, theft and other fraudulent practices occur from time-to-time in certain of the jurisdictions in which we may operate or sell our products. While we strictly prohibit our employees and agents from engaging in such conduct and have established procedures, controls and training to prevent such conduct from occurring, it is possible that our employees or agents will engage in such conduct and that we might be held responsible. If our employees or other agents are alleged or are found to have engaged in such practices, we could incur significant costs and suffer severe penalties or other consequences that may have a material adverse effect on our business, financial condition and results of operations.

Provisions contained in our certificate of incorporation and bylaws could impair or delay stockholders' ability to change our management and could discourage takeover transactions that some stockholders might consider to be in their best interests.

Provisions of our certificate of incorporation and bylaws could impede attempts by our stockholders to remove or replace our management and could discourage others from initiating a potential merger, takeover or other change of control transaction, including a potential transaction at a premium over the market price of our common stock, that our stockholders might consider to be in their best interests. Such provisions include:

Our corporate headquarters, located at 20 Florence Avenue, Batavia, New York, consists of a 45,000 square foot building. Our manufacturing facilities, also located in Batavia, consist of approximately 3342 acres and contain about 260,000 square feet in several buildings, including 206,000 square feet in manufacturing facilities, 48,000 square feet for warehousing and a 6,000 square-foot building for product research and development. Additionally, we lease an approximately 1,500 square foot U.S. sales office in Houston, Texas and GVHTT leases an approximately 4,900 square foot sales and engineering office in Suzhou, China. ~~In fiscal 2019, the Company established Graham India Private Limited ("GIPL") as a wholly-owned subsidiary.~~ GIPL, located in Ahmedabad, India, serves as a sales and market development office focusing on the refining, petrochemical and fertilizer markets. We lease a sales and marketing office of approximately 777 square feet in Ahmedabad, India.

~~For our business held for sale, we lease approximately 15,000 square feet of office space and 45,000 square feet of manufacturing facilities.~~

We believe that our properties are generally in good condition, are well maintained, and are suitable and adequate to carry on our business.

The information required by this Item 3 is contained in Note 1817 to our consolidated financial statements included in Item 8 of Part II of this Annual Report on Form 10-K and is incorporated herein by reference.

Our common stock is traded on the NYSE exchange under the symbol "GHM". As of May ~~23, 2019,~~26, 2021, there were ~~9,842,803~~9,950 shares of our common stock outstanding that were held by approximately ~~138~~128 stockholders of record.

Subject to the rights of any preferred stock we may then have outstanding, the holders of our common stock are entitled to receive dividends as may be declared from time to time by our Board of Directors out of funds legally available for the payment of dividends. Our Board of Directors declared dividends per share of ~~$0.09~~$0.11 for ~~the first quarter of fiscal 2019 and $0.10 in~~ each of the ~~second, third and fourth~~four quarters of fiscal ~~2019.~~2021. While we anticipate that we will continue to pay quarterly cash dividends in the future, there can be no assurance that we will pay such dividends in any future period or that the level of cash dividends paid by us will remain constant.

Our senior credit facility contains provisions pertaining to the maintenance of a maximum funded debt to earnings before interest expense, income taxes, depreciation and amortization, or EBITDA, ratio and a minimum ~~level of~~ earnings before interest expense and income taxes to interest ratio as well as restrictions on the payment of dividends to stockholders. The facility limits the payment of dividends to stockholders to 25% of net income if our funded debt to EBITDA ratio is greater than 2.0 to 1. As of March 31, ~~2019~~2021 and May 31, ~~2019~~2021 we did not have any funded debt outstanding. More information regarding our senior credit facility can be found in Note 9 to the Consolidated Financial Statements included in Item 8 of Part II of this Annual Report on Form 10-K.

~~Our global~~The ongoing slowdown in our energy and petrochemical markets (which we refer to as our "commercial markets") began during the latter part of fiscal 2020 and was caused primarily by an excess supply of crude oil, which had ~~been~~a negative impact on commodity pricing. This caused more measured investment in maintenance and capital projects within our commercial markets. The economic slowdown and corresponding reductions in demand for transportation fuel and petrochemical products caused by the ongoing COVID-19 global pandemic further adversely affected our commercial markets. As a ~~significant downturn~~result of these combined adverse supply-side and demand-side disruptions, our commercial customers have significantly reduced their operating budgets for ~~several years, began to show signs~~the types of ~~stabilization~~products and ~~improvement during the second half of fiscal 2018~~services we provide. The timing and ~~which continued through fiscal 2019. Such stabilization~~catalyst for a recovery in ~~crude oil prices and improvement in general global economic conditions have led to increased activity by~~ our ~~customers~~commercial markets remains uncertain. Accordingly, we believe that in the ~~downstream energy sector. Customers have begun~~near term the quantity of projects available for us to ~~invest in upgrading~~compete for will be fewer and ~~turnaround maintenance for existing facilities and, in certain geographies, are beginning to look at new capacity. While this additional activity is encouraging, we cannot predict~~that the ~~pace at which a recovery~~pricing environment will ~~progress or if it will continue.~~ remain challenging.

~~Our long-term view~~We believe chemical and petrochemical capital investment will continue to decouple from energy investment. Over the long term, we expect that population growth, an expanding global middle class and an increasing desire for improved quality of life and access to consumer products will drive increased demand for industrial goods within the plastics and resins value chain along with fertilizers or related products. Consequently, when global economies return to stable growth, we expect investment in new global chemical and petrochemical capacity will resume and that such investments will drive growth in demand for our products and services.

Energy markets, in particular crude oil refining, simultaneous with the above-described slowdown, are undergoing a more fundamental evolution. We believe that systemic changes in the energy markets are occurring and that such changes are being driven, in part, by the increasing use by consumers of alternative fuels in lieu of fossil fuels. As a result, we anticipate demand growth for fossil-based fuels will be less than the global ~~energy~~GDP growth rate. Accordingly, we expect that crude oil refiners will focus new investments toward the installed base, and that inefficient refineries will close and new refining capacity will be co-located where fuels and petrochemicals are produced. We also anticipate that future investment by refiners in renewable fuels (e.g., renewable diesel), in existing refineries (e.g., to expand feedstock processing flexibility and to improve conversion of oil to refined products), to gain greater throughput, or to build new capacity (e.g., integrated refineries with petrochemical ~~markets is that general economic fundamentals~~products capabilities) will continue to drive ~~increasing~~ demand for our products and result in continued capital investment to satisfy increasing global energy demand. These fundamentals include rising populations, strong emerging market economic growth, and overall global economic expansion.services.

International sales increased ~~$6,806~~$12,203, or ~~27%,~~37% compared with fiscal ~~2018.~~2020. By market, sales for fiscal ~~2019~~2021 were ~~50%~~41% to the refining industry (up from ~~28%~~37% in fiscal ~~2018)~~2020), ~~18%~~24% to the chemical and petrochemical industries (down from ~~27%~~34% in fiscal ~~2018)~~2020), ~~11%~~25% from the defense industry (U.S. Navy) (up from 16% in fiscal 2020), and 10% to ~~the power~~other commercial and industrial markets (down from ~~14%~~13% in fiscal ~~2018), and 21% to defense and other industrial applications (down from 31%~~2020).

The COVID-19 pandemic impacted our financial results in fiscal ~~2018).~~2021. We estimated that revenue was adversely impacted by COVID-19 by approximately $5,500. This included the benefit of approximately $5,000 which moved into fiscal 2021 from fiscal 2020 related to a project fabricated in China which was delayed in late fiscal 2020. Across fiscal 2021, especially in the first quarter, we had production capacity impacted at our Batavia, New York facility. In the first quarter of fiscal 2021, we limited production at our production facility in Batavia, New York and averaged approximately 50% of capacity during that quarter. We had additional impacts across all quarters, although not to the extent we saw in the first quarter. We are committed to diligently protecting our workforce while endeavoring to minimize any unfavorable impact to our business and our customers.

Our gross margin for fiscal ~~2019~~2021 was ~~23.9%~~21.0% compared with ~~21.9%~~20.0% for fiscal ~~2018.~~2020. The increase in gross margin was primarily due to ~~an improved pricing environment and increased utilization of capacity.~~lower production costs. Gross profit for fiscal ~~2019~~2021 increased ~~$4,934,~~$2,321, or ~~29%~~13%, compared with fiscal ~~2018 due to~~2020 on higher volume and higher gross margin as noted above, compared with fiscal ~~2018.~~2020.

SG&A expense for fiscal ~~2019~~2021 was ~~$17,878,~~$17,471, up ~~13%~~4%, or ~~$2,109,~~$592, compared with ~~$15,769~~$16,879 in fiscal ~~2018.~~2020. SG&A as a percentage of sales in fiscal ~~2019~~2021 was ~~19.5%~~17.9% of sales compared with ~~20.3%~~18.6% of sales in fiscal ~~2018.~~

During the fourth quarter of fiscal 2019, we decided to sell our commercial nuclear utility business that we operate under our wholly-owned subsidiary Energy Steel. We reviewed the market value of the business at such time and determined the assets to be impaired based on such market value. We also estimated the fair value of the commercial nuclear utility business related to the carrying value of Energy Steel. The impairment review indicated that the fair value of the intangible assets, goodwill and other long-lived assets of the business2020. SG&A increases were ~~negligible,~~primarily due to ~~erosion of the Energy Steel business~~increased variable compensation and commercial nuclear utility industry. As a result, we recorded impairment losses of $1,700, $2,000, $1,208, $1,222, and $319 for permits, tradename, customer relationships, goodwill, and other long-lived assets, respectively. The total impairment charge was $6,449 before taxes and $5,320 after taxes. The remaining value of the business is net working capital.

During the third quarter of fiscal 2018, we performed our annual goodwill and intangible asset impairment review. We estimated the fair value of intangible assets and goodwill of our commercial nuclear utility business related to the December 2010 acquisition of Energy Steel. The impairment review indicated that the fair value of the permits, tradename and goodwill of the business were substantially lower than the carrying value due to reduced investment from the U.S. commercial nuclear utility market, the strength of the Energy Steel brand relative to larger more vertically integrated suppliers, and the bankruptcy of Westinghouse Electric Company which resulted in the stoppage of work at the Summer, South Carolina nuclear facility. As a result, we recorded impairment losses of $8,600, $500, and $5,716 for permits, tradename, and goodwill, respectively. The total impairment charge was $14,816 before taxes and $12,014 after taxes. Additionally, we incurred a $46 revenue reversal, and a $234 bad debt charge, related to the bankruptcy of Westinghouse Electric Company and the stoppage of work at the Summer, South Carolina nuclear facility. The total before and after tax cost of these two charges was $280 and $193, respectively. Additionally, we recognized a benefit of $786 related to the revaluation of deferred tax liabilities, which were impacted by the reduction in federal income tax rates from the Tax Act. The deferred tax benefit of $786 included $839 of expense for adjusting the rates on the deferred tax liability of the Energy Steel acquisitionoutside sales agent commissions, partly offset by ~~a benefit of $1,625 for other tax items.~~

~~In fiscal 2018, we incurred a pre-tax restructuring charge of $316 ($224 after tax) for severance costs related to certain headcount reductions. There were no such charges in fiscal 2019.~~

Interest income for fiscal ~~2019~~2021 was ~~$1,462, up~~$167, down from ~~$606~~$1,324 in fiscal ~~2018, primarily as a result of higher interest rates.~~2020. Interest expense ~~for fiscal 2019 was $12, the same amount as~~ in fiscal ~~2018.~~

Our effective tax rate ~~was not meaningful~~ in fiscal ~~2019, as we had a~~2021 was 27% compared with 19% in fiscal 2020. The increase in tax ~~expense despite a pre-tax loss,~~rate was primarily due to ~~non-deductibility~~the mix of the goodwill portion of the write down for our commercial nuclear utility business. Excluding the impact of the impairment losses we incurred from our commercial nuclear utility business, our effectiveearnings by geography, which were in higher tax rate in fiscal 2019 was 20%. This compares to an effective tax rate in fiscal 2018 of 23%. Excluding the impact of the impairment losses we incurred from our commercial nuclear utility business and the impact of the Tax Act, our effective tax rate in fiscal 2018 was 31%.

~~Net (loss) and (loss) per diluted share for fiscal 2019, were ($308) and ($0.03), respectively,~~cost areas as compared with ~~net (loss) and (loss) per diluted share of ($9,844) and ($1.01), respectively, for fiscal 2018.

~~The following discussion should be read in conjunction with our consolidated statements of changes in stockholders~~' ~~equity that can be found in Item 8 of Part II of this Annual Report on Form 10-K. The following table shows the balance of stockholders' equity on the dates indicated:~~

Stockholders' equity decreased $4,383 or 4%, at March 31, 2019 compared with March 31, 2018. The decrease was primarily due to the impairment and other charges related to our commercial nuclear utility business offset partially by earnings.

~~On March 31, 2019, our net book value per share was $10.05, down from $10.58 at March 31, 2018.~~

The following discussion should be read in conjunction with our consolidated statements of cash flows and consolidated balance sheets appearing in Item 8 of Part II of this Annual Report on Form 10-K:

We invest net cash generated from operations in excess of cash held for near-term needs in short-term, less than 365 days, certificates of deposit, money market accounts or U.S. government instruments, generally with maturity periods of up to 180 days. Our ~~money market account is~~certificates of deposit are used to securitize our outstanding letters of credit, which reduces our cost on those letters of credit.

Capital expenditures for the fiscal year ending March 31, ~~2020 (which~~2022, which we refer to as "fiscal ~~2020")~~2022," are expected to be between approximately ~~$2,500~~$2,800 and ~~$2,800.~~$3,000. Approximately ~~75% to 80%~~90% of our fiscal ~~2020~~2022 capital expenditures are expected to be for machinery and equipment, with the remaining amounts expected to be used for other items.

Our revolving credit facility with JP Morgan Chase, N.A. ("JP Morgan Chase") provides us with a line of credit of ~~$25,000, including~~$22,000, which includes a separate line of $7,000 for letters of credit and bank guarantees. In addition, our JP Morgan Chase agreement allows us to increase the line of credit, at our discretion, up to another ~~$25,000,~~$15,000, for total availability of ~~$50,000.~~$37,000. Borrowings under this credit facility are secured by all of our assets. We also ~~have~~had a ~~$5,000 unsecured line~~$15,000 letter of credit facility with HSBC, N.A. ("HSBC"). at March 31, 2021 secured by certain of our deposit accounts with HSBC. Letters of credit outstanding on March 31, ~~2019~~2021 and March 31, ~~2018~~2020 were ~~$8,503~~$11,567 and ~~$8,233,~~$13,328, respectively. The outstanding letters of credit as of March 31, ~~2019~~2021 were issued by JP Morgan Chase ~~HSBC, as well as Bank of America, N.A. (under our previous credit facility).~~and HSBC. There were no other amounts outstanding on our credit facilities at March 31, ~~2019~~2021 and March 31, ~~2018.~~2020. The borrowing rate under our JP Morgan Chase facility as of March 31, ~~2019~~2021 was the bank’s prime rate, or ~~5.50%~~3.25%. Availability under the JP Morgan Chase and HSBC lines of credit was ~~$22,505~~$25,433 and ~~$24,336~~$21,672 at March 31, ~~2019~~2021 and March 31, ~~2018,~~2020, respectively.

We did not have any off-balance sheet arrangements as of March 31, 2021 and 2020, other than letters of credit incurred in the ordinary course of business.

We believe that cash generated from operations, combined with the liquidity provided by our investments and available financing capacity under our credit facility, will be adequate both to meet our cash needs for the immediate future and to support our growth strategies.

On February 4, 2003, we terminated postretirement healthcare benefits for our U.S. employees. Benefits payable to retirees of record on April 1, 2003 remained unchanged. We expect to be required to make cash contributions in connection with these plans beyond one year, but such amounts cannot be estimated. No contributions are expected to be made to our defined benefit pension ~~plan~~plans for fiscal ~~2020.~~2022.

Management uses orders and backlog as measures of our current and future business and financial performance. Orders in fiscal ~~2019 decreased 10%~~2021 increased 52% to ~~$101,241~~$121,619 from ~~$112,230~~$80,034 in fiscal ~~2018. Orders in fiscal 2019, excluding the business held for sale, were $90,222, down from $104,611 in fiscal 2018.~~2020. Orders represent communications received from customers requesting us to supply products and services. Revenue is recognized on orders received in accordance with our revenue recognition policy described in Notes 1 and 2 to the consolidated financial statements contained in Item 8 of Part II of this Annual Report on Form 10-K.

Domestic orders were ~~61%~~73%, or ~~$62,205,~~$89,283, and international orders were ~~39%~~27%, or ~~$39,036, of our total net orders in fiscal 2019. This compared to net domestic orders of $77,126, or 69%, of total net orders, and international orders of $35,104, or 31%,~~$32,336, of our total orders in fiscal ~~2018.~~2021. This compared with domestic orders of $43,045, or 54% of total orders, and international orders of $36,989, or 46% of our total orders in fiscal 2020. Domestic orders increased by $46,238, or 107%. This increase was due to a large increase in defense (U.S. Navy) orders, partly offset by lower domestic commercial orders. Net international orders decreased by ~~$14,921,~~$4,653, or ~~19% as a result of weaker orders for the U.S. Navy business (we received an atypical order for approximately $25,000 for work related to the U.S. Navy~~13% in fiscal ~~2018) and refining market, offset by increased demand in the petrochemical processing and nuclear market industries. Net international orders increased by $3,932, or 11% in fiscal 2019.~~2021.

Backlog was ~~$132,127~~$137,567 at March 31, ~~2019,~~2021, up ~~12%~~22% compared with ~~$117,946~~$112,389 at March 31, ~~2018. Backlog was $124,088, excluding the commercial nuclear utility business which is being held for sale.~~2020. Backlog is defined by us as the total dollar value of orders received for which revenue has not yet been recognized. All orders in backlog represent orders from our traditional markets in established product lines. We had no projects cancelled in fiscal 2021. Approximately ~~55%~~40% to ~~60%~~45% of orders currently in our backlog are expected to be converted to sales within one year. At March 31, ~~2019,~~2021, approximately ~~22%~~16% of our backlog was attributed to equipment for refinery project work, ~~19%~~6% for chemical and petrochemical projects, ~~7% for power, including nuclear energy (89% of which is now considered held for sale as noted above), 49%~~76% for U.S. Navy projects and 3%2% for other industrial or commercial applications. At March 31, ~~2018,~~2020, approximately ~~30%~~27% of our backlog was attributed to equipment for refinery project work, 5%17% for chemical and petrochemical projects, ~~5% for power, including nuclear energy, 56%~~52% for U.S. Navy projects and 4% for other commercial nuclear energy, other industrial or commercial applications. At March 31, ~~2019,~~2021, we had no projects on hold. At March 31, 2020, we had two projects totaling $562 on hold.

On June 1, 2021, we acquired Barber-Nichols, Inc. ("BNI"), a privately-owned designer and manufacturer of turbomachinery products for the aerospace, cryogenic, defense and energy markets and is located in Arvada, Colorado. We believe that this acquisition furthers our growth strategy through market and product diversification, broadens its offerings to the defense and energy markets and strengthens its presence in the defense sector.

Under the terms of the stock purchase agreement, the purchase price of $70,113 is comprised of 610 shares of our common stock, representing a value of approximately $8,963, and cash consideration of $61,150, subject to certain potential adjustments, including a customary working capital adjustment. The stock purchase agreement also includes a contingent earn-out dependent upon certain financial measures of BNI post-acquisition, in which the sellers are eligible to receive up to $14,000 in additional cash consideration.

On June 1, 2021, we entered into a $20,000 five-year term loan with Bank of America. The term loan requires monthly principal payments of $167 through June 1, 2026, with the remaining principal amount due on the maturity date. The interest rate on the term loan is the applicable Bloomberg Short-Term Bank Yield Index ("BSBY") plus 1.50%, subject to a 0.00% floor. In addition, on June 1, 2021, we entered into a revolving credit facility with Bank of America that provides a $30,000 line of credit, including letters of credit and bank guarantees, expandable at our option and the bank’s approval at any time up to $40,000. The agreement has a five-year term. Amounts outstanding under the facility agreement will bear interest at a rate equal to BSBY plus 1.50%, subject to a 0.00% floor. Outstanding letters of credit under the agreement are subject to a fee of 1.50%. The upfront fee for each of the term loan and revolving credit facility is .20% of the committed facilities and amounts available for borrowing under the revolving credit facility are subject to an unused commitment fee of .25% Under the term loan agreement and revolving credit facility, we covenant to maintain a maximum total leverage ratio, as defined in such agreements, of 3.0 to 1.0, a minimum fixed charge coverage ratio, as defined in such agreements, of 1.20 to 1.0 and minimum margined assets, as defined in such agreements, of 100% of total amounts outstanding on the revolving credit facility, including letters of credit.

On June, 1, 2021, we entered into an agreement to amend the letter of credit facility agreement with HSBC Bank USA, N.A. and decreased our line of credit from $15,000 to $7,500. Under the amended agreement, we incur an annual facility fee of $5 and outstanding letters of credit are subject to a fee of between .75% and .85%, depending on the term of the letter of credit. Interest is payable on the principal amounts of unreimbursed letter of credit draws under the facility at a rate of 3% plus the bank’s prime rate.

WeNear term opportunities in the global energy and petrochemical markets have slowed significantly due to the combined impact of the COVID-19 pandemic and the geopolitical imbalance of supply, as previously discussed. Although we do not know when the COVID-19 pandemic will end or when the supply imbalance will subside, we continue to believe ~~in the long-term strength of~~ the energy markets will improve. In addition, we believe the petrochemical markets provide long-term growth opportunities for our products and ~~petrochemical markets.~~services.

We intend to continue to look for organic growth opportunities as well as acquisitions or other business ~~combinations~~combinations that we believe will allow us to expand our presence in both our existing and ancillary markets. ~~We are focused on reducing earnings volatility, growing our business and diversifying our business and product lines.~~

~~We expect revenue~~Our expectations for sales and profitability assume that we are able to operate our production facility in Batavia, New York at or near normal ("pre-COVID-19") capacity throughout fiscal 2020 to be approximately $95,000 to $100,000; this excludes the commercial nuclear utility business which is held for sale. This would be an anticipated increase of 14% to 20% when compared with $83,495 for fiscal 2019 when excluding the held for sale business.2022. We project that approximately ~~55%~~40% to ~~60%~~45% of our $137,567 March 31, ~~2019~~2021 backlog ~~excluding backlog held for sale,~~ will convert to sales in fiscal ~~2020.~~2022. We expect the remaining backlog will convert beyond fiscal ~~2020,~~2022, which includes a combination of U.S. Navy orders that have a long conversion cycle (up to five years) as well as certain commercial orders, the conversion of which has been extended by our customers.

We ~~expect gross profit margin~~had no projects cancelled in fiscal ~~2020 to be in the 23% to 24% range, compared with 23.9%~~2021. At March 31, 2021, we had no projects put on hold by our customers.

We have been named as a defendant in lawsuits alleging personal injury from exposure to asbestos allegedly contained in, or accompanying, our products. We are a co-defendant with numerous other defendants in these lawsuits and intend to vigorously defend ourselves against these claims. The claims are similar to previous asbestos lawsuits that named us as a defendant. Such previous lawsuits either were dismissed when it was shown that we had not supplied products to the plaintiffs’ places of work or were settled by us for immaterial amounts. We cannot provide any assurances that any pending or future matters will be resolved in the same manner as previous lawsuits.

As of March 31, ~~2019,~~2021, we are subject to the claims noted above, as well as other legal proceedings and potential claims that have arisen in the ordinary course of business. Although the outcome of the lawsuits to which we are, or may become, a party to cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made for the majority of claims, we do not believe that the outcomes, either individually or in the aggregate, will have a material adverse effect on our results of operations, financial position or cash flows.

The discussion and analysis of our financial condition and results of operations are based upon the consolidated financial statements and the notes to consolidated financial statements included in Item 8 of Part II of this Annual Report on Form 10-K, which have been prepared in accordance with accounting principles generally accepted in the U.S.

Critical accounting policies are defined as those that reflect significant judgments and uncertainties and could potentially result in materially different results under different assumptions and conditions.

Revenue Recognition. The Company accounts for revenue in accordance with Accounting Standard Codification 606, "Revenue from Contracts with Customers" ("ASC 606")~~, which it adopted on April 1, 2018 using the modified retrospective approach.~~.

We recognize revenue on all contracts when control of the product is transferred to the customer. Control is generally transferred when products are shipped, title is transferred, significant risks of ownership have transferred, we have rights to payment, and rewards of ownership pass to the customer. Customer acceptance may also be a factor in determining whether control of the product has transferred. Although revenue on the majority of our contracts, as measured by number of contracts, is recognized upon shipment to the customer, revenue on larger contracts, which are fewer in number but generally represent the majority of revenue, is recognized over time as these contracts meet specific criteria in ASC 606.

~~Valuation~~Revenue from contracts that is recognized upon shipment accounted for approximately 40% of ~~Goodwill and Intangible Assets.~~ ~~Definite lived intangible assets are amortized~~revenue in fiscal 2021. Revenue from contracts that is recognized over ~~their estimated useful lives and are assessed~~time accounted for impairment if certain indicators are present. Goodwill and intangible assets deemed to have indefinite lives are not amortized but are subject to impairment testing annually or earlier if an event or changeapproximately 60% of revenue in ~~circumstances indicates that~~fiscal 2021. We recognize revenue over time when contract performance results in the ~~fair value~~creation of a ~~reporting unit may~~product for which we do not have ~~been reduced below its carrying value. If the fair value of a reporting unit is less than its carrying value,~~ an impairment loss, limited to the amount of goodwill allocated to that reporting unit, is recorded. Fair values for reporting units are determined based on a weighted combination of the market approachalternative use and the ~~income approach using discounted cash flows. Indefinite lived intangible assets are assessed for impairment by comparing~~contract includes an enforceable right to payment in an amount that corresponds directly with the ~~fair~~ value of the ~~asset~~performance completed. To measure progress towards completion on performance obligations for which revenue is recognized over time we utilize an input method based upon a ratio of direct labor hours incurred to ~~its carrying value.~~date to management’s estimate of the total labor hours to be incurred on each contract or an output method based upon completion of operational milestones, depending upon the nature of the contract.

Pension and Postretirement Benefits. Defined benefit pension and other postretirement benefit costs and obligations are dependent on actuarial assumptions used in calculating such amounts. These assumptions are reviewed annually and include the discount rate, long-term expected rate of return on plan assets, salary growth, healthcare cost trend rate and other economic and demographic factors. We base the discount rate assumption for our plans on ~~Moody's or Citigroup~~the FTSE Pension Liability ~~Index AA-rated corporate long-term bond yield rate.~~Above-Median AA-Index. The long-term expected rate of return on plan assets is based on the plan’s asset allocation, historical returns and expectations as to future returns that are expected to be realized over the estimated remaining life of the plan liabilities that will be funded with the plan assets. The salary growth assumptions are determined based on long-term actual experience and future and near-term outlook. The healthcare cost trend rate assumptions are based on historical cost and payment data, the near-term outlook, and an assessment of likely long-term trends.

~~Income Taxes.~~ We use the liability method to account for income taxes. Under this method, deferred tax liabilities and assets are recognized for the tax effects of temporary differences between the financial reporting and tax bases of liabilities and assets measured using the enacted tax rate.30

Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using current tax rates. We evaluate available information about future taxable income and other possible sources of realization of deferred income tax assets and record valuation allowances to reduce deferred income tax assets to an amount that represents our best estimates of the amounts of such deferred income tax assets that more likely than not will be realized.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. Significant judgment is required in evaluating our tax positions and determining our provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. We establish reserves for uncertain tax positions when we believe that certain tax positions do not meet the more likely than not threshold. We adjust these reserves in light of changing facts and circumstances, such as the outcome of a tax audit or the lapse of the statute of limitations. The provision for income taxes includes the impact of reserve provisions and changes to the reserves that are considered appropriate.

We have evaluated the accounting policies used in the preparation of the consolidated financial statements and the notes to consolidated financial statements included in Item 8 of Part II of this Annual Report on Form 10-K and believe those policies to be reasonable and appropriate.

We believe that the most critical accounting estimates used in the preparation of our consolidated financial statements relate to labor hour estimates and establishment of operational milestones which are used to recognize revenue over time, ~~fair value estimates of goodwill and identifiable tangible and intangible assets acquired in business combinations,~~ accounting for contingencies, under which we accrue a loss when it is probable that a liability has been incurred and the amount can be reasonably estimated, and accounting for pensions and other postretirement benefits.

As discussed above under the heading "Critical Accounting Policies," we recognize a majority of our revenue using an over-time recognition method. The key estimate for the over-time recognition model is total labor to be incurred on each contract and to the extent that this estimate changes, it may significantly impact revenue recognized in each period.

As a result of the adoption of ASC 606, we anticipate certain large international contracts will not qualify for over-time revenue recognition which may cause inordinate quarter-to-quarter and year-to-year financial performance volatility.

Goodwill and intangible assets with indefinite lives are tested annually for impairment. We assess goodwill for impairment by comparing the fair value of its reporting units to their carrying amounts. If the fair value of a reporting unit is less than its carrying value, an impairment loss, limited to the amount of goodwill allocated to that reporting unit, is recorded. Fair values for reporting units are determined based on a weighted combination of the market approach and the income approach using discounted cash flows. Indefinite lived intangible assets are assessed for impairment by comparing the fair value of the asset to its carrying value.

Contingencies, by their nature, relate to uncertainties that require us to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss. For more information on these matters, see the notes to consolidated financial statements included in Item 8 of Part II of this Annual Report on Form 10-K.

Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about inflation, investment returns, mortality, turnover, medical costs and discount rates. These assumptions are reviewed annually.

The discount rate used in accounting for pensions and other postretirement benefits expense (income) is determined in conjunction with our actuary by reference to a current yield curve and by considering the timing and amount of projected future benefit payments. The discount rate assumption for fiscal ~~2019~~2021 was ~~3.95%~~3.44% for our defined benefit pension ~~plan~~plans and ~~3.63%~~3.01% for our other postretirement benefit plan. A reduction in the discount rate of 50 basis points, with all other assumptions held constant, would have increased fiscal ~~2019~~2021 net periodic benefit expense for our defined benefit pension ~~plan~~plans and other postretirement benefit plan by approximately ~~$451~~$352 and $0, respectively.

The expected return on plan assets assumption of ~~8.0%~~6.5% used in accounting for our pension plan is determined by evaluating the mix of investments that comprise plan assets and external forecasts of future long-term investment returns. A reduction in the rate of return of 50 basis points, with other assumptions held constant, would have increased fiscal ~~2019~~2021 net periodic pension expense by approximately ~~$191.~~$193.

As part of our ongoing financial reporting process, a collaborative effort is undertaken involving our managers with functional responsibilities for financial, credit, tax, engineering, manufacturing and benefit matters, and outside advisors such as lawyers, consultants and actuaries. We believe that the results of this effort provide management with the necessary information on which to base their judgments and to develop the estimates and assumptions used to prepare the financial statements.

We believe that the amounts recorded in the consolidated financial statements included in Item 8 of Part II of this Annual Report on Form 10-K related to revenue, contingencies, pensions, other postretirement benefits and other matters requiring the use of estimates and judgments are reasonable, although actual outcomes could differ materially from our estimates.

In the normal course of business, management evaluates all new accounting pronouncements issued by the Financial Accounting Standards Board, the SEC, the Emerging Issues Task Force, the American Institute of Certified Public Accountants or any other authoritative accounting body to determine the potential impact they may have on our consolidated financial statements. For

discussion of the newly issued accounting pronouncements see ''~~Accounting~~''Accounting and reporting ~~changes~~changes''' in Note 1 to the Consolidated Financial Statements included in Item 8 of Part II of this Annual Report on Form 10-K.

~~We did not have any off-balance sheet arrangements as of March 31, 2019 or March 31, 2018, other than operating leases and letters of credit incurred in the ordinary course of business.~~

The principal market risks (i.e., the risk of loss arising from market changes) to which we are exposed are foreign currency exchange rates ~~price risk~~ and ~~project cancellation~~price risk.

The assumptions applied in preparing the following qualitative and quantitative disclosures regarding foreign currency exchange rate, price risk and project cancellation risk are based upon volatility ranges experienced by us in relevant historical periods, our current knowledge of the marketplace, and our judgment of the probability of future volatility based upon the historical trends and economic conditions of the markets in which we operate.

International consolidated sales for fiscal ~~2019~~2021 were ~~35%~~46% of total sales, up from ~~33%~~36% of sales in fiscal ~~2018.~~2020. Operating in markets throughout the world exposes us to movements in currency exchange ~~rates.~~rates, including the recent increased volatility in foreign currency exchange rates resulting from the COVID-19 pandemic. Currency movements can affect sales in several ways, the foremost being our ability to compete for orders against foreign competitors that base their prices on relatively weaker currencies. Business lost due to competition for orders against competitors using a relatively weaker currency cannot be quantified. In addition, cash can be adversely impacted by the conversion of sales made by us in a foreign currency to U.S. dollars. In fiscal ~~2019,~~2021, substantially all sales by us and our wholly owned subsidiaries, for which we ~~or our subsidiaries~~ were paid, were denominated in the local currency of the respective subsidiary (U.S. dollars or Chinese RMB).

We have limited exposure to foreign currency purchases. In fiscal ~~2019,~~2021, our purchases in foreign currencies represented 2%1% of the cost of products sold. At certain times, we may enter into forward foreign currency exchange agreements to hedge our exposure against potential unfavorable changes in foreign currency values on significant sales and purchase contracts negotiated in foreign currencies. Forward foreign currency exchange contracts were not used in fiscal ~~2019~~2021 and as of March 31, ~~2019,~~2021, we held no forward foreign currency contracts.

Operating in a global marketplace requires us to compete with other global manufacturers which, in some instances, benefit from lower production costs and more favorable economic conditions. Although we believe that our customers differentiate our products on the basis of our manufacturing quality and engineering experience and excellence, among other things, such lower production costs and more favorable economic conditions mean that ~~certain of~~ our competitors are able to offer products similar to ours at lower prices. In extreme market downturns, such as we recently experienced, we typically see depressed price levels. Moreover, the cost of metals and other materials used in our products have experienced significant volatility. Such factors, in addition to the global effects of the recent volatility and disruption of the capital and credit markets, have resulted in downward demand and pricing pressure on our products.

Adverse economic or specific project conditions can lead to a project being placed on hold or cancelled by our customers. In fiscal 2019 and fiscal 2018, we had no projects cancelled. At March 31, 2019, we had no projects on hold. We attempt to mitigate the risk of cancellation by structuring contracts with our customers to maximize the likelihood that progress payments made to us for individual projects cover the costs we have incurred. As a result, we do not believe we have a significant cash exposure to projects which may be cancelled.

Open orders are reviewed continuously through communications with customers. If it becomes evident to us that a project is delayed well beyond its original shipment date, management will move the project into "placed on hold" (i.e., suspended) category. Furthermore, if a project is cancelled by our customer, it is removed from our backlog.

Graham Corporation, and its operating subsidiaries, (together, the "Company"), is a global designer, manufacturer and supplier of vacuum and heat transfer equipment used in the energy, defense, chemical and petrochemical ~~petroleum refining, and electric power generating~~ industries. During the fiscal year ended March 31, 2020 the Company sold its wholly-owned subsidiary, Energy Steel & Supply Co. ("Energy Steel"), ~~a wholly-owned subsidiary, is a nuclear code accredited fabrication and specialty machining company which provides products to~~located in Lapeer, Michigan. The accompanying Consolidated Financial Statements include the ~~commercial nuclear utility industry.~~results of operations of Energy Steel for the period April 1, 2018 through June 23, 2019. During the fiscal year ended March 31, 2019, the Company established Graham India Private Limited ("GIPL") as a wholly-owned subsidiary. GIPL, located in Ahmedabad, India, serves as a sales and market development office focusing on the refining, petrochemical and fertilizer markets. The Company's significant accounting policies are set forth below.

The Company's fiscal years ended March 31, ~~2019, 2018~~2021, 2020 and ~~2017~~2019 are referred to as "fiscal ~~2019,~~2021," "fiscal ~~2018"~~2020" and "fiscal ~~2017,~~2019," respectively.

Principles of consolidation and use of estimates in the preparation of consolidated financial statements

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Energy Steel, located in Lapeer, Michigan, Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd., located in China, and GIPL, located in India. All intercompany balances, transactions and profits are eliminated in consolidation.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the related revenues and expenses during the reporting period. Actual amounts could differ from those estimated.

Assets and liabilities of the Company's foreign subsidiary are translated into U.S. dollars at currency exchange rates in effect at ~~year-end~~year end and revenues and expenses are translated at average exchange rates in effect for the year. Gains and losses resulting from foreign currency transactions are included in results of operations. The Company's sales and purchases in foreign currencies are minimal. Therefore, foreign currency transaction gains and losses are not significant. Gains and losses resulting from translation of foreign subsidiary balance sheets are included in a separate component of stockholders' equity. Translation adjustments are not adjusted for income taxes since they relate to an investment, which is permanent in nature.

The Company accounts for revenue in accordance with Accounting Standard Codification 606, "Revenue from Contracts with Customers" ("ASC 606")~~, which it adopted on April 1, 2018 using the modified retrospective approach. See the~~ ~~Accounting and report changes~~ ~~section below for further discussion of this adoption.~~.

The Company recognizes revenue on all contracts when control of the product is transferred to the customer. Control is generally transferred when products are shipped, title is transferred, significant risks of ownership have transferred, the Company has rights to payment, and rewards of ownership pass to the customer. Customer acceptance may also be a factor in determining whether control of the product has transferred. Although revenue on the majority of the Company’s contracts, as measured by number of contracts, is recognized upon shipment to the customer, revenue on larger contracts, which are fewer in number but generally represent the majority of revenue, is recognized over time as these contracts meet specific criteria in ASC 606.

Cash and cash equivalents consist of cash and highly liquid, short-term investments with maturities at the time of purchase of three months or less.

Shipping and handling fees billed to the customer are recorded in net sales and the related costs incurred for shipping and handling are included in cost of products sold.

Investments consist of certificates of deposits with financial institutions. All investments have original maturities of greater than three months and less than one year and are classified as held-to-maturity, as the Company believes it has the intent and ability to hold the securities to maturity. The investments are stated at amortized cost which approximates fair value. All investments held by the Company at March 31, ~~2019~~2021 are scheduled to mature on or before ~~September 25, 2019.~~June 24, 2021.

Inventories are stated at the lower of cost or net realizable value, using the average cost method. Unbilled revenue (contract assets) in the Consolidated Balance Sheets represents revenue recognized that has not been billed to customers on contracts in which revenue is recognized over time. ~~Upon adoption of the new revenue recognition guidance discussed in the~~ ~~"Accounting and report changes"~~ ~~section below, all~~All progress payments exceeding unbilled revenue are presented as customer deposits (contract liabilities) in the Consolidated Balance Sheets. Under the previous guidance, progress payments exceeding unbilled revenue were netted against inventory to the extent the payment was less than or equal to the inventory balance relating to the applicable contract, and the excess was presented as customer deposits in the Consolidated Balance Sheet.

Property, plant and equipment are stated at cost net of accumulated depreciation and amortization. Major additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. Depreciation and amortization are provided based upon the estimated useful lives, or lease term if shorter, under the straight-line method. Estimated useful lives range from approximately ~~five~~three to eight years for office equipment, eight to 25 years for manufacturing equipment and 40 years for buildings and improvements. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

The Company records its business combinations under the acquisition method of accounting. Under the acquisition method of accounting, the Company allocates the purchase price of each acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition. The fair value of identifiable intangible assets is based upon detailed valuations that use various assumptions made by management. Any excess of the purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Direct acquisition-related costs are expensed as incurred.

Acquired intangible assets other than goodwill consist of permits, customer relationships, and tradenames. The Company amortizes its definite-lived intangible assets on a straight-line basis over their estimated useful lives. The estimated useful life is fifteen years for customer relationships. All other intangibles have indefinite lives and are not amortized.

The Company assesses the impairment of definite-lived long-lived assets or asset groups when events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that are considered in deciding when to perform an impairment review include: a significant decrease in the market price of the asset or asset group; a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction; a current-period operating or 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 use of a long-lived asset or asset group; or a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The term more likely than not refers to a level of likelihood that is more than 50%.

Recoverability potential is measured by comparing the carrying amount of the asset or asset group to its related total future undiscounted cash flows. If the carrying value is not recoverable through related cash flows, the asset or asset group is considered to be impaired. Impairment is measured by comparing the asset or asset group's carrying amount to its fair value. When it is determined that useful lives of assets are shorter than originally estimated, and no impairment is present, the rate of depreciation is accelerated in order to fully depreciate the assets over their new shorter useful lives.

Goodwill and intangible assets with indefinite lives are tested annually for ~~impairment as of December 31.~~impairment. The Company assesses goodwill for impairment by comparing the fair value of its reporting units to their carrying amounts. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill within the reporting unit is less than its carrying value. Fair values for reporting units are determined based on a weighted combination of the market approach and the income approach using discounted cash flows. Indefinite lived intangible assets are assessed for impairment by comparing the fair value of the asset to its carrying value.

The Company classifies long-lived assets (disposal group) to be sold as held for sale in accordance with Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operation And Disclosures of Disposals Of Components Of An Entity," in the period in which all of the following criteria are met:

A long-lived asset (disposal group) that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale.

The fair value of a long-lived asset (disposal group) less any costs to sell is assessed at each reporting period it remains classified as held for sale and any subsequent changes are reported as an adjustment to the carrying value of the asset (disposal group), as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. Upon determining that a long-lived asset (disposal group) meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group for all periods presented in the line items "Assets held for sale" and "Liabilities held for sale," respectively, in the Consolidated Balance Sheet as of March 31, 2019. See Note 3.

The Company estimates the costs that may be incurred under its product warranties and records a liability in the amount of such costs at the time revenue is recognized. The reserve for product warranties is based upon past claims experience and ongoing evaluations of any specific probable claims from customers. A reconciliation of the changes in the product warranty liability is presented in Note 7.

Research and development costs are expensed as incurred. The Company incurred research and development costs of ~~$3,538, $3,211~~$3,367, $3,353 and ~~$3,863~~$3,538 in fiscal ~~2019,~~2021, fiscal ~~2018~~2020 and fiscal ~~2017,~~2019, respectively. Research and development costs are included in the line item “Cost of products sold” in the Consolidated Statements of Operations.

The Company recognizes deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using currently enacted tax rates. The Company evaluates the available evidence about future taxable income and other possible sources of realization of deferred income tax assets and records a valuation allowance to reduce deferred income tax assets to an amount that represents the Company's best estimate of the amount of such deferred income tax assets that more likely than not will be realized.

The Company accounts for uncertain tax positions using a "more likely than not" recognition threshold. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective resolution of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. These tax positions are evaluated on a quarterly basis. It is the Company's policy to recognize any interest related to uncertain tax positions in interest expense and any penalties related to uncertain tax positions in selling, general and administrative expense.

The Company files federal and state income tax returns in several U.S. and non-U.S. domestic and foreign jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed.

The Company records compensation costs related to ~~stock-based~~equity-based awards based on the estimated fair value of the award on the grant date. Compensation cost is recognized in the Company's Consolidated Statements of Operations over the applicable vesting period. The Company uses the Black-Scholes valuation model as the method for determining the fair value of its stock option awards. For service and performance based restricted stock awards, the fair market value of the award is determined based upon the closing value of the Company's stock price on the grant date. The fair market value of market-based performance restricted stock awards is determined using the Monte Carlo valuation model. The amount of ~~stock-based~~equity-based compensation expense recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company estimates the forfeiture rate at the grant date by analyzing historical data and revises the estimates in subsequent periods if the actual forfeiture rate differs from the estimates.

Basic income (loss) ~~income~~ per share is computed by dividing net income (loss) ~~income~~ by the weighted average number of common shares outstanding for the period. Diluted income (loss) ~~income~~ per share is calculated by dividing net income (loss) ~~income~~ by the weighted average number of common shares outstanding and, when applicable, potential common shares outstanding during the period.

None of the options to purchase shares of common stock which totaled 3937 and 6939 in fiscal ~~2019~~2021 and fiscal ~~2018,~~2019, respectively, were included in the computation of diluted loss per share as the affect would be anti-dilutive given their exercise price as they would not be dilutive upon issuance or due to the net losses in the fiscal years. There were 11 options to purchase shares of common stock at various exercise prices in fiscal 2017 which were not included in the computation of diluted income per share as the affect would be anti-dilutive given their exercise prices.year.

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents.

Interest paid was $11 in fiscal 2021 and $12 in each of fiscal ~~2019, $12 in~~2020 and fiscal ~~2018, and $10 in fiscal 2017.~~2019. In addition, income taxes paid (refunded) ~~paid~~ were $200 in fiscal 2021, $139 in fiscal 2020 and $(73) in fiscal ~~2019, $1,916 in fiscal 2018 and $951 in fiscal 2017.~~2019.

In fiscal ~~2019,~~2021, fiscal ~~2018~~2020 and fiscal ~~2017,~~2019, non-cash activities included pension and other postretirement benefit income (loss) adjustments, net of income tax, of ~~$348, $(1,668)~~$1,774, $(525) and ~~$(2,493)~~$(348), respectively. In fiscal 2018, non-cash activities included the reclassification of $1,828 from accumulated other comprehensive loss to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the "Tax Act"). Also, in fiscal ~~2019,~~2021, fiscal ~~2018~~2020 and fiscal ~~2017,~~2019, non-cash activities included the issuance of treasury stock valued at ~~$134, $130~~$222, $170 and ~~$241,~~$134, respectively, to the Company's Employee Stock Purchase Plan (See Note 13).

At March 31, ~~2019, 2018~~2021, 2020 and ~~2017,~~2019, there were ~~$85, $0,~~$173, $162 and ~~$4,~~$85, respectively, of capital purchases that were recorded in accounts payable and are not included in the caption "Purchase of property, plant and equipment" in the Consolidated Statements of Cash Flows. In fiscal ~~2019,~~2021, fiscal ~~2018~~2020 and fiscal ~~2017,~~2019, capital expenditures totaling ~~$100,~~$0, $0 and ~~$95,~~$100, respectively, were financed through the issuance of capital leases.

Comprehensive income (loss) is comprised of net income and other comprehensive income or loss items, which are accumulated as a separate component of stockholders' equity. For the Company, other comprehensive income or loss items include a foreign currency translation adjustment and pension and other postretirement benefit adjustments.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. The accounting standard for fair value establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

Level 2 – Valuations determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date.

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 disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of sales and expenses during the reporting period. Actual results could differ materially from those estimates.

In the normal course of business, management evaluates all new accounting pronouncements issued by the Financial Accounting Standards Board ("FASB"), the Securities and Exchange Commission ("SEC"), the Emerging Issues Task Force, the American Institute of Certified Public Accountants or any other authoritative accounting body to determine the potential impact they may have on the Company's consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This guidance establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company’s contracts with customers. The guidance requires companies to apply a five-step model when recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also includes a comprehensive set of disclosure requirements regarding revenue recognition. The guidance allows two methods of adoption: (1) a full retrospective approach where historical financial information is presented in accordance with the new standard and (2) a modified retrospective approach where the guidance is applied to the most current period presented in the financial statements. In August 2015, the FASB issued ASU No 2015-14 "Revenue from Contracts with Customers: Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, with earlier application permitted as of annual reporting periods beginning after December 15, 2016. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," to clarify the implementation guidance on principal versus agent. In April 2016, the FASB issued ASU No. 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," which clarifies the identifying performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients," which clarifies the implementation guidance related to collectability, presentation of sales tax, noncash consideration, contract modifications and completed contracts at transition.

The Company adopted the revenue recognition standard using the modified retrospective approach on April 1, 2018. The Company recognized the cumulative effect of initially applying the new standard to all contracts that were not completed on the date of adoption as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standard in effect during those periods. The most significant impact of adopting the guidance is the timing of revenue recognition. Revenue on the majority of the Company's contracts continues to be recognized upon shipment while revenue on its larger contracts is recognized over time as these contracts meet specific criteria established in the new standards. Consistent with previous guidance, revenue recognized on contracts over time created unbilled revenue (contract assets) and reduced inventory on the Company's Consolidated Balance Sheets. Upon adoption of the new standard, progress payments for which the Company has received an unconditional right to payment are recognized as trade accounts receivable with a corresponding contract liability of an equal amount as customer deposits on the Company's Consolidated Balance Sheets since the related performance obligations have not been satisfied. Under the previous guidance, progress payments were recognized when payment was received. In addition, progress payments exceeding unbilled revenue were netted against inventory to the extent the payment was less than or equal to the inventory balance relating to the applicable contract and the excess was presented as customer deposits.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires companies to recognize all leases as assets and liabilities on the consolidated balance sheet. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. This ASU retains a distinction between finance leases and operating leases, and the classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the current accounting guidance. As a result, the effect of leases on the consolidated statement of comprehensive income and the consolidated statement of cash flows is largely unchanged from previous generally accepted accounting principles. The guidance requires application on a modified retrospective basis based on the earliest period presented in the consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842) Targeted Improvements, " which provides an additional transition method that allows entities to initially apply the guidance at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. In addition, the guidance provides a practical expedient that allows entities to account for lease components and associated nonlease components as a single component if specific conditions are met. The amendments in these ASUs are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted.

The Company will adopt these standards using the modified retrospective approach on April 1, 2019. The Company will elect an available transition method that uses the effective date of the amended guidance as the date of initial application. The Company has completed its review of its lease agreements and processed the data required to measure the Company’s right of use assets and lease liabilities.

The amended guidance provides for several practical expedients. The Company will elect the package of practical expedients permitted under the transition guidance which allows entities to carry forward historical lease classification. The Company will elect the practical expedient that allows the combination of both lease and non-lease components as a single component and account for it as a lease for all classes of underlying assets. The Company will make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. The Company will recognize those lease payments in the Consolidated Statement of Operations on a straight-line basis over the lease term. On April 1, 2019, the Company will recognize the cumulative effect of initially applying the amended guidance which will result in the recognition of right of use assets of approximately $700, lease liabilities of approximately $750 and a decrease to the opening balance of retained earnings of approximately $80. Other current assets and the deferred income tax liability will also be reduced by approximately $50 and $20, respectively. Approximately $500 of right of use assets and lease liabilities are related to the business held for sale.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230)," which clarifies the presentation and classification of eight specific issues on the cash flow statement. This ASU is effective for public businesses for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted the new guidance in fiscal 2019. The adoption of this ASU did not have a material impact on the Company'~~s Consolidated Financial Statements.~~

In March 2017, the FASB issued ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715)," which amended its guidance related to the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amended guidance requires the service cost component be disaggregated from the other components of net benefit cost. The service cost component of expense is required to be reported in the Statement of Operations in the same line item as other compensation costs within income from operations. The other components of net benefit cost are required to be presented separately from the service cost component outside of income from operations. The amended guidance also allows only the service cost component of net benefit cost to be eligible for capitalization. This ASU is effective for public businesses for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted the amended guidance in fiscal 2019. The amended guidance was applied retrospectively for the presentation of the service cost component and other components of net benefit cost in the Consolidated Statements of Operations. In addition, the amended guidance was applied prospectively for the capitalization of the service cost component of net benefit cost. The amended guidance allows for a practical expedient that permits the use of amounts previously disclosed in the Employee Benefit Plans Note to the Consolidated Financial Statements within prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company elected this practical expedient for the prior period presentation. The adoption of this amended guidance resulted in the reclassification of net benefit income of $355 and $123 from compensation costs included in Cost of products sold and Selling, general and administrative expense, respectively, to Other income in the Consolidated Statement of Operations for fiscal 2018 and the reclassification of net benefit income of $4 and $6 from compensation costs included in Cost of products sold and Selling, general and administrative expense, respectively, to Other income in the Consolidated Statement of Operations for fiscal 2017.

In August 2018, the FASB issued ASU No. 2018-14, ~~"Compensation-Retirement Benefits-Defined~~"Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit ~~Plans-General (Subtopic 715-20),~~Plans," which removes disclosures that no longer are considered cost beneficial, clarifies specific disclosure requirements and adds disclosure requirements identified as relevant for defined benefit pension and other postretirement benefit plans. This amendment is effective for fiscal years ending after December 15, 2020. ~~Early adoption is permitted.~~ The amendment requires application on a retrospective basis to all periods presented. The Company adopted the new guidance in fiscal 2021. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements.

In December 2019, the FASB issue ASU No. 2019-12, "Simplifying the Accounting for Income Taxes." The amended guidance simplifies the accounting for income taxes, eliminating certain exceptions to the general income tax principles, in an effort to reduce the cost and complexity of application. The amended guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Earlier application is permitted. The guidance requires application on either a prospective, retrospective or modified retrospective basis, contingent on the income tax exception being applied. The Company believes the adoption of this ASU will not have a material impact on its Consolidated Financial Statements.

Management does not expect any other recently issued accounting pronouncements, which have not already been adopted, to have a material impact on the Company's consolidated financial statements.

The Company accounts for revenue in accordance with Accounting Standard Codification 606, "Revenue from Contracts with Customers" ("ASC 606"), which it adopted on April 1, 2018 using the modified retrospective approach. See Note 1 to the Consolidated Financial Statements for further discussion of this adoption.

A performance obligation represents a promise in a contract to provide a distinct good or service to a customer and is the unit of accounting pursuant to ASC 606. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Transaction price reflects the amount of consideration to which the Company expects to be entitled in exchange for transferred products. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized as the performance obligation is satisfied. In certain cases, the Company may separate a contract into more than one performance obligation, while in other cases, several products may be part of a fully integrated solution and are bundled into a single performance obligation. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods underlying each performance obligation. The Company has made an accounting policy election to exclude from the measurement of the contract price all taxes assessed by government authorities that are collected by the Company from its customers. The Company does not adjust the contract price for the effects of a financing component if the Company expects, at contract inception, that the period between when a product is transferred to a customer and when the customer pays for the product will be one year or less. Shipping and handling fees billed to the customer are recorded in revenue and the related costs incurred for shipping and handling are included in cost of products sold.

Revenue on the majority of the Company’s contracts, as measured by number of contracts, is recognized upon shipment to the customer, however, revenue on larger contracts, which are fewer in number but generally represent the majority of revenue, is recognized over time as these contracts meet specific criteria established in ASC 606. Revenue from contracts that is recognized upon shipment accounted for approximately 40%, 30% and 40% of revenue in fiscal ~~2019.~~2021, fiscal 2020 and fiscal 2019, respectively. Revenue from contracts that is recognized over time accounted for approximately 60%, 70% and 60% of revenue in fiscal ~~2019.~~2021, fiscal 2020 and fiscal 2019, respectively. In fiscal 2021, revenue recognized over time as a percentage of total revenue was lower as compared with the prior year due to limited production on large contracts during the first quarter of fiscal 2021 as a result of the COVID-19 pandemic, as well as the completion of two large projects in China which did not meet the criteria for recognizing revenue over time. The Company recognizes revenue over time when contract performance results in the creation of a product for which the Company does not have an alternative use and the contract includes an enforceable right to payment in an amount that corresponds directly with the value of the performance completed. To measure progress towards completion on performance obligations for which revenue is recognized over time the Company utilizes an input method based upon a ratio of direct labor hours incurred to date to management’s estimate of the total labor hours to be incurred on each contract or an output method based upon completion of operational milestones, depending upon the nature of the contract. The Company has established the systems and procedures essential to developing the estimates required to account for performance obligations over time. These procedures include monthly review by management of costs incurred, progress towards completion, identified risks and opportunities, sourcing determinations, changes in estimates of costs yet to be incurred, availability of materials, and execution by subcontractors. Sales and earnings are adjusted on a cumulative catch-up basis in current accounting periods based upon revisions in the contract value due to pricing changes and estimated costs at completion. Losses on contracts are recognized immediately when evident to management.

The timing of revenue recognition, invoicing and cash collections affect trade accounts receivable, unbilled revenue (contract assets) and customer deposits (contract liabilities) on the Consolidated Balance Sheets. Unbilled revenue represents revenue on contracts that is recognized over time and exceeds the amount that has been billed to the customer. Unbilled revenue is separately presented in the Consolidated Balance Sheets. The Company may receive a customer deposit or have an unconditional right to receive a customer deposit prior to revenue being recognized. Because the performance obligations related to such customer deposits may not have been satisfied, a contract liability is recorded and an offsetting asset of equal amount is recorded as a trade accounts receivable until the deposit is collected. Customer deposits are separately presented in the Consolidated Balance Sheets. Customer deposits are not considered a significant financing component as they are generally received less than one year before the product is completed or used to procure specific material on a contract, as well as related overhead costs incurred during design and construction.

Contract liabilities at March 31, ~~2019~~2021 and ~~April 1, 2018~~2020 include ~~$6,382~~$1,603 and ~~$2,220,~~$3,660, respectively, of customer deposits for which the Company has an unconditional right to collect payment. Trade accounts receivable, as presented on the Consolidated Balance Sheets, ~~and within Note 1,~~ includes corresponding balances at March 31, ~~2019~~2021 and ~~April 1, 2018,~~2020, respectively. Revenue recognized in fiscal ~~2019~~2021 that was included in the contract liability balance at ~~April 1, 2018~~March 31, 2020 was ~~$10,680.~~$20,833. Changes in the net contract liability balance during fiscal ~~2019~~2021 were impacted by a ~~$1,430~~$5,402 increase in contract assets, of which ~~$7,626~~$29,836 was due to contract progress offset by invoicing to customers of ~~$5,894 and the reclassification of unbilled revenue of $302 to assets held for sale.~~$24,434. In addition, contract liabilities ~~increased $4,262~~decreased $12,924 driven by new customer deposits of ~~$16,875~~$7,909 offset by revenue recognized in fiscal ~~2019~~2021 that was included in the contract liability balance at ~~April 1, 2018 and the reclassification of customer deposits of $1,933 to liabilities held for sale.~~March 31, 2020.

Receivables billed but not paid under retainage provisions in the Company’s customer contracts were ~~$2,214~~$3,747 and ~~$1,124~~$2,016 at March 31, ~~2019~~2021 and ~~2018,~~2020, respectively.

Incremental costs to obtain a contract consist of sales employee and agent commissions. Commissions paid to employees and sales agents are capitalized when paid and amortized to selling, general and administrative expense when the related revenue is recognized. Capitalized costs, net of amortization, to obtain a contract were ~~$133~~$39 and ~~$118~~$45 at March 31, ~~2019~~2021 and ~~April 1, 2018,~~2020, respectively, and are included in the line item "Prepaid expenses and other current assets" in the Consolidated Balance Sheets. The related amortization expense was $600, $169 and $168 in fiscal ~~2019.~~2021, fiscal 2020 and fiscal 2019, respectively.

The Company's remaining unsatisfied performance obligations represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company also refers to this measure as backlog. As of March 31, ~~2019,~~2021, the Company had remaining unsatisfied performance obligations of ~~$132,127, of which $8,039 was held for sale.~~$137,567. The Company expects to recognize revenue on approximately ~~55%~~40% to ~~60%~~45% of the remaining performance obligations within one year, ~~10%~~20% to ~~15%~~30% in one to two years and the remaining beyond two years.

In March 2019, the Company's Board of Directors approved a plan to sell Energy Steel. Energy Steel met all of the criteria to classify its assets and liabilities as held for sale ~~in the fourth quarter of fiscal~~at March 31, 2019. The potential disposal of Energy Steel does not represent a strategic shift that will have a major effect on the Company’s operations and financial results and is, therefore, not classified as discontinued operations in accordance with ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operation And Disclosures of Disposals Of Components Of An Entity." As part of the required assessment under the held for sale guidance, the Company determined that the approximate fair value less costs to sell the operations was less than its carrying value and, as a result, an impairment loss totaling $6,449 was recorded in fiscal 2019. (See Note 6 to the Consolidated Financial Statements for further discussion.)

In fiscal 2020 the Company completed the sale of Energy Steel. Under the terms of the stock purchase agreement, the Company received proceeds of $602, subject to certain adjustments, including a customary working capital adjustment. The ~~following table reconciles~~Company recognized a loss on the ~~major classes~~disposal of ~~assets~~$181. In addition, in fiscal 2020 the Company incurred a bad debt charge of $98 and ~~liabilities classified as held for sale~~an inventory write down of $338 related to the bankruptcy of Westinghouse Electric Company. All of these items are included in the line item "Other expense" in the Consolidated ~~Balance Sheet:~~

~~Subsequent to March 31, 2019, the Company received an offer for the purchase of Energy Steel.~~

Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives. Intangible amortization expense was $0, $0 and $180 in ~~each of~~fiscal 2021, fiscal 2020 and fiscal 2019, ~~fiscal 2018 and fiscal 2017.~~

During the third quarter of fiscal 2018, the Company performed its annual goodwill and intangible asset impairment review. The Company assesses impairment by comparing the fair value of its reporting units and intangible assets to their related carrying value. The Company estimated the fair value of intangible assets and goodwill of its commercial nuclear utility business related to the December 2010 acquisition of Energy Steel using the income approach. Under the income approach, the fair value of the business is calculated based on the present value of estimated future cash flows. Cash flow projections are based on management’s estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on a weighted average cost of capital adjusted for the relevant risk associated with the characteristics of the business and the projected cash flows. The inputs utilized in the analyses are classified as Level 3 inputs within the fair value hierarchy. The impairment review indicated that the fair value of the permits, tradename and goodwill of the business were substantially lower than the carrying value due to reduced investment from the U.S. commercial nuclear utility market, the strength of the Energy Steel brand relative to larger more vertically integrated suppliers, and the bankruptcy of Westinghouse Electric Company which resulted in the stoppage of work at the Summer, South Carolina nuclear facility. As a result, in the third quarter of fiscal 2018 the Company recorded impairment losses of $8,600, $500, and $5,716 for permits, tradename and goodwill, respectively.

During the third quarter of fiscal 2019, the Company performed its annual goodwill and intangible asset impairment review based on a weighted combination of the market approach and the income approach as described above. The review indicated that there was no impairment of goodwill and intangible assets.

As disclosed in Note 3, in ~~the fourth quarter of~~ fiscal 2019, the ~~Company’s~~Company's Board of Directors approved a plan to sell Energy ~~Steel and, as~~Steel. As a result, ~~the Company classified the assets and liabilities of Energy Steel as "Assets held for sale" and "Liabilities held for sale" in the Consolidated Balance Sheet as of March 31, 2019. An~~an impairment loss totaling $6,449 was recorded ~~in the fourth quarter of fiscal 2019~~ related to the disposition of Energy Steel which included impairment losses of $1,700, $2,000, $1,208, $1,222 and $319 for permits, tradename, customer relationships, goodwill and other long-lived ~~assets.~~

~~Goodwill was $0 and $1,222 at March 31, 2019 and 2018,~~assets, respectively. In fiscal 2020, the Company completed the sale of Energy Steel.

The reconciliation of the changes in the product warranty liability is as follows:

The product warranty liability is included in the line item "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets.

The Company leases ~~equipment~~certain manufacturing facilities, office space, machinery and office ~~space under various~~equipment. An arrangement is considered to contain a lease if it conveys the right to use and control an identified asset for a period of time in exchange for consideration. If it is determined that an arrangement contains a lease, then a classification of a lease as operating ~~leases. Lease expense applicable~~or finance is determined by evaluating the five criteria outlined in the lease accounting guidance at inception. Leases generally have remaining terms of one year to five years, whereas leases with an initial term of twelve months or less are not recorded on the Consolidated Balance Sheets. The depreciable life of leased assets related to finance leases is limited by the expected term of the lease, unless there is a transfer of title or purchase option that the Company believes is reasonably certain of exercise. Certain leases include options to renew or terminate. Renewal options are exercisable per the discretion of the Company and vary based on the nature of each lease. The term of the lease includes renewal periods only if the Company is reasonably certain that it will exercise the renewal option. When determining if a renewal option is reasonably certain of being exercised, the Company considers several factors, including but not limited to, the cost of moving to another location, the cost of disrupting operations, whether the purpose or location of the leased asset is unique and the contractual terms associated with extending the lease. The Company’s lease agreements do not contain any residual value guarantees or any material restrictive covenants and the Company does not sublease to any third parties. As of March 31, 2021, the Company did not have any material leases that have been signed but not commenced.

Right-of-use ("ROU") lease assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments in exchange for that right of use. Finance lease ROU assets and operating ~~leases was $572, $581 and $615~~lease ROU assets are included in ~~fiscal 2019, fiscal 2018 and fiscal 2017, respectively.~~

The current portion and non-current portion of finance and operating lease liabilities are all presented separately in the Consolidated Balance Sheets.

The discount rate implicit within the Company's leases is generally not readily determinable, and therefore, the Company uses an incremental borrowing rate in determining the present value of lease payments based on rates available at commencement.

The weighted average remaining lease term and discount rate for finance and operating leases ~~which have been capitalized:~~are as follows:

The Company and its subsidiaries had no0 short-term borrowings outstanding at March 31, ~~2019~~2021 and ~~2018.~~2020.

On December 2, ~~2015,~~2020, the Company entered into a revolving credit facility agreement with JPMorgan Chase Bank, N.A. that provides a ~~$25,000~~$22,000 line of credit, expandable at the Company's option and upon the bank's approval at any time up to $37,000, including a $7,000 commitment for letters of credit and bank ~~guarantees, expandable at the Company's option at any time up to $50,000.~~guarantees. The agreement has a ~~five-year~~one-year term.

At the Company's option, amounts outstanding under the agreement will bear interest at either: (i) a rate equal to the bank's prime rate; or (ii) a rate equal to LIBOR plus ~~a margin. The margin is based on the Company's funded debt to earnings before interest expense, income taxes, depreciation and amortization ("EBITDA") and may range from~~ 1.75% ~~to 0.95%~~. Amounts available for borrowing under the agreement are subject to an unused commitment fee of ~~between 0.30% and 0.20%, depending on the above ratio.~~0.375%. The bank’s prime rate was ~~5.50% and 4.75%~~3.25% at March 31, ~~2019~~2021 and ~~2018, respectively.~~2020.

Outstanding letters of credit under the agreement are subject to a fee of ~~between 1.20% and 0.70%, depending on the Company's ratio of funded debt to EBITDA.~~0.75%.

At March 31, ~~2019,~~2021, there were ~~$4,763~~$5,416 letters of credit outstanding on the JPMorgan Chase Bank, N.A. revolving credit ~~facility and $1,008 with Bank of America, N.A.~~facility. Availability under the line of credit was ~~$20,237~~$16,584 at March 31, ~~2019.~~2021.

Under the revolving credit facility, the Company covenants to maintain a maximum funded debt to ~~EBITDA~~earnings before interest expense, income taxes, depreciation and amortization ("EBITDA") ratio, as defined in such credit facility, of 3.5 to 1.0 and a minimum earnings before interest expense and income taxes ("EBIT") to interest ratio, as defined in such credit facility, of 4.0 to 1.0. The agreement also provides that the Company is permitted to pay dividends without limitation if it maintains a maximum funded debt to EBITDA ratio equal to or less than 2.0 to 1.0 and permits the Company to pay dividends in an amount equal to 25% of net income if it maintains a funded debt to EBITDA ratio of greater than 2.0 to 1.0. The Company was in compliance with all such provisions as of and for the years ended March 31, ~~2019~~2021 and ~~2018.~~2020. Assets with a book value of ~~$137,075~~$117,360 have been pledged to secure borrowings under the credit facility.

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, investments, and trade accounts receivable. The Company places its cash, cash equivalents, and investments with high credit quality financial institutions, and evaluates the credit worthiness of these financial institutions on a regular basis. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers comprising the Company's customer base and their geographic dispersion. At March 31, ~~2019~~2021 and ~~2018,~~2020, the Company had no significant concentrations of credit risk.

The Company has entered into standby letter of credit agreements with financial institutions relating to the guarantee of future performance on certain contracts. At March 31, ~~2019~~2021 and ~~2018,~~2020, the Company was contingently liable on outstanding standby letters of credit aggregating ~~$8,503~~$11,567 and ~~$8,233,~~$13,328, respectively.

The Company, as a result of its global operating and financial activities, is exposed to market risks from changes in foreign exchange rates. In seeking to minimize the risks and/or costs associated with such activities, the Company may utilize foreign exchange forward contracts with fixed dates of maturity and exchange rates. The Company does not hold or issue financial instruments for trading or other speculative purposes and only holds contracts with high quality financial institutions. If the counter-

parties to any such exchange contracts do not fulfill their obligations to deliver the contracted foreign currencies, the Company could be at risk for fluctuations, if any, required to settle the obligation. At March 31, 2019 and 2018, there were no foreign exchange forward contracts held by the Company.

The estimates of the fair value of financial instruments are summarized as follows:

Cash and cash equivalents: The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturity of these instruments and are considered Level 1 assets in the fair value hierarchy.

Investments: The fair value of investments at March 31, ~~2019~~2021 and ~~2018~~2020 approximated the carrying value and are considered Level 2 assets in the fair value hierarchy.

The foreign deferred income tax asset of ~~$37~~$0 and ~~$15~~$48 at March 31, ~~2019~~2021 and ~~2018,~~2020, respectively, is included in the caption "Other assets" in the Consolidated Balance ~~Sheet.~~Sheets. Deferred income taxes include the impact of state investment tax credits of ~~$275,~~$321, which expire from ~~2020~~2022 to ~~2033~~2035 and state investment tax credits of $794, which have an unlimited carryforward period.

Foreign net operating losses at March 31, 2019 were $200 and expire between 2021 through 2023. Net operating losses attributable to Energy Steel, the subsidiary held for sale, for city income taxes were $4,279 at March 31, 2019 and have an indefinite life.

In assessing the realizability of deferred tax assets, management considers, within each taxing jurisdiction, whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the consideration of the weight of both positive and negative evidence, management determined that a portion of the deferred tax assets as of March 31, ~~2019~~2021 and ~~2018~~2020 related to certain state investment tax credits and the capital loss related to ~~the subsidiary held for sale~~Energy Steel would not be realized, and recorded a valuation allowance of ~~$4,917~~$5,326 and ~~$1,074,~~$5,319, respectively. The deferred tax asset of $126 included in the caption "Assets held for sale" in the Consolidated Balance Sheet includes a valuation allowance of $34 related to net operating loss carryforwards for city income taxes.

The Company files federal and state income tax returns in several domestic and international jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed. The Company is subject to U.S. federal examination for tax years ~~2015~~2017 through ~~2018~~2020 and examination in state tax jurisdictions for tax years ~~2014~~2016 through ~~2018.~~2020. The Company is subject to examination in the People's Republic of China for tax years ~~2015~~2017 through ~~2018.~~2020 and in India for tax years 2018 through 2020. The liability for unrecognized tax benefits was $0 at each of March 31, ~~2019~~2021 and ~~2018.~~2020.

On ~~December 22, 2017,~~March 27, 2020, President Trump signed the ~~Tax~~Coronavirus Aid, Relief, and Economic Security ("CARES") Act ~~was signed~~ into law. The ~~Tax~~CARES Act ~~significantly revised the U.S.~~included several significant business tax ~~code by,~~provisions that, among other ~~changes, lowering~~things, would eliminate the taxable income limit for certain net operating losses and allow businesses to carry back net operating losses arising in 2018, 2019 and 2020 to the five prior tax years, accelerate refunds of previously generated corporate ~~income~~alternative minimum tax ~~rate~~credits, change the business interest limitation under IRC section 163(j) from ~~35%~~30% to ~~21%~~50%, ~~requiring~~and fix qualified improvement property from the Tax Cuts and Jobs Act (the "Tax Act"). These provisions did not have a one-time transition tax on accumulated foreign earnings of certain foreign subsidiaries that were previously tax deferred and creating new taxes on certain foreign sourced earnings. The Company remeasured certain U.S. deferred tax assets and liabilities basedmaterial impact on the ~~rates at which they are expected to reverse in the future, which is generally 21%, and recorded an income tax benefit of $971 related to such re-measurement in fiscal 2018.~~

The one-time transition tax is based on the total post-1986 earnings and profits (“E&P”) of our foreign subsidiary that has previously been deferred from U.S. income taxes. The Company recorded its one-time transition liability of its foreign subsidiary resulting in additional income tax expense of $185 in fiscal 2018. The transition tax is based in part on the amount of those earnings held in cash and other specified assets.

The Tax Act also includes two new U.S. tax base-erosion provisions, the global intangible low-taxed income ("GILTI") provisions and the base-erosion and anti-abuse tax ("BEAT") provisions, beginning in 2018. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred and has recorded $11 of tax related to GILTI in fiscal 2019. The BEAT provisions in the Tax Act eliminate the deduction of certain base-erosion payments made to related foreign corporations and impose a minimum tax if greater than regular tax. The Company was not subject to this tax, and therefore has not included any tax impacts of BEAT in itsCompany’s consolidated financial statements.

The Tax Act also provides tax incentives to U.S. companies to earn income from the sale, lease or license of goods and services abroad in the form of a deduction for foreign-derived intangible income ("FDII"). FDII is taxed at an effective rate of 13.125% for taxable years beginning after December 31, 2017. The incremental U.S. tax savings on FDII in fiscal 2019 was $69.

The U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. The Company recognized the provisional tax impacts related to the revaluation of deferred tax assets and liabilities and included the amount in its consolidated financial statements in fiscal 2018 and during fiscal 2019 there were no significant changes made to the provisional amounts recorded in fiscal 2018.

The Company has a qualified defined benefit plan covering U.S. employees hired prior to January 1, 2003, which is non-contributory. Benefits are based on the employee's years of service and average earnings for the five highest consecutive calendar years of compensation in the ten-year period preceding retirement. The Company's funding policy for the plan is to contribute the amount required by the Employee Retirement Income Security Act of 1974, as amended.

During fiscal ~~2019~~2021 and fiscal ~~2018,~~2020, the pension plan released liabilities for vested benefits of certain participants through the purchase of nonparticipating annuity contracts with a third-party insurance company. As a result of these transactions, in fiscal ~~2019~~2021 and fiscal ~~2018,~~2020, the projected benefit obligation ~~decreased $1,589 and $890, respectively,~~ and plan assets decreased ~~$1,718~~$1,477 and ~~$998~~$1,420, respectively. The projected benefit obligation is the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated future pay increases. The accumulated benefit obligation reflects the actuarial present value of benefits attributable to employee service rendered to date, but does not include the effects of estimated future pay increases. The accumulated benefit obligation as of March 31, ~~2019~~2021 and ~~2018~~2020 was ~~$30,380~~$32,861 and ~~$30,385,~~$31,715, respectively. At March 31, ~~2019~~2021 and ~~2018,~~2020, the pension plan was fully funded on an accumulated benefit obligation basis.

Amounts recognized in accumulated other comprehensive loss, net of income tax, consist of:

The increase in accumulated other comprehensive loss, net of income tax, consists of:

~~The estimated net actuarial loss for the pension plan that will be amortized from accumulated other comprehensive loss into net pension cost in fiscal 2020 is $969.~~

The weighted average asset allocation of the plan assets by asset category is as follows:

				March 31,									March 31,
Asset Category	Target Allocation			2019			2018			Target Allocation			2021			2020
Equity securities		50	%		49	%		67	%		30	%		33	%		30	%

					100	%		100	%					100	%		100	%

The investment strategy of the plan is to generate a consistent total investment return sufficient to pay present and future plan benefits to retirees, while minimizing the long-term cost to the Company. Target allocations for asset categories are used to earn a reasonable rate of return, provide required liquidity and minimize the risk of large losses. Targets are adjusted when considered necessary to reflect trends and developments within the overall investment environment. ~~In fiscal 2019, the target allocation was adjusted to 50% from 65% for equity securities and to 50% from 35% for debt securities.~~

The fair values of the Company's pension plan assets at March 31, ~~2019~~2021 and ~~2018,~~2020, by asset category, are as follows:

On February 4, 2003, the Company closed the defined benefit plan to all employees hired on or after January 1, 2003. In place of the defined benefit plan, these employees participate in the Company's domestic defined contribution plan. The Company contributes a fixed percentage of employee compensation to this plan on an annual basis for these employees. The Company contribution to the defined contribution plan for these employees in fiscal ~~2019,~~2021, fiscal ~~2018~~2020 and fiscal ~~2017~~2019 was ~~$325, $284~~$430, $406 and ~~$286,~~$325, respectively.

The Company has aan unfunded Supplemental Executive Retirement Plan ("SERP") which provides retirement benefits associated with wages in excess of the legislated qualified plan maximums. Pension expense recorded in fiscal ~~2019,~~2021, fiscal ~~2018,~~2020, and fiscal ~~2017~~2019 related to this plan was $105, $85 and $97, ~~$115~~respectively. The weighted average discount rate used to determine pension expense for this plan was 3.44%, 3.83% and ~~$128,~~3.95% for fiscal 2021, fiscal 2020 and fiscal 2019, respectively. The weighted average rate of increase in compensation levels used to develop pension expense for this plan was 3% in each of fiscal 2021, fiscal 2020 and fiscal 2019. At March 31, ~~2019~~2021 and ~~2018,~~2020, the ~~related liability~~projected benefit obligation was ~~$662~~$1,557 and ~~$582, respectively. The current portion of the related liability was $0~~$747, respectively, and ~~$17 at March 31, 2019 and 2018~~ is ~~included~~separately presented in the caption ~~"Accrued Compensation" and the long-term portion is included in~~ "Accrued Pension Liability" in the Consolidated Balance Sheets. The amounts recognized in accumulated other comprehensive loss, net of income tax, consist of a net actuarial loss of $544 and $0 at March 31, 2021 and 2020, respectively.

The Company has a domestic defined contribution plan (401k) covering substantially all employees. The Company provides matching contributions equal to 100% of the first 3% of an employee's salary deferral and 50% of the next 2% percent of an employee’s salary deferral. Company contributions are immediately vested. Contributions were $863 in fiscal 2021, $1,000 in fiscal 2020 and $1,135 in fiscal ~~2019, $805 in fiscal 2018 and $873 in fiscal 2017.~~2019.

In addition to providing pension benefits, the Company has a plan in the U.S. that provides health care benefits for eligible retirees and eligible survivors of retirees. The Company's share of the medical premium cost has been capped at $4 for family coverage and $2 for single coverage for early retirees, and $1 for both family and single coverage for regular retirees.

On February 4, 2003, the Company terminated postretirement health care benefits for its U.S. employees. Benefits payable to retirees of record on April 1, 2003 remained unchanged.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, ~~2019~~2021 and ~~2018,~~2020, and the results of its operations and its cash flows for each of the three years in the period ended March 31, ~~2019,~~2021, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of March 31, 2019 based on criteria established in ~~Internal Control — Integrated Framework (2013)~~ issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 31, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for revenue from contracts with customers in fiscal year 2019 due to the adoption of Accounting Standards Update No. 2014-09, ~~Revenue from Contracts with Customers (Topic 606), issued by the Financial Accounting Standards Board~~. ~~The Company adopted the standard using the modified retrospective approach.~~

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the ~~PCAOB~~Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition — Over time – Input Method – Refer to Notes 1 and 2 to the financial statements

The Company recognizes a majority of its revenue over time when contract performance results in the creation of a product for which the Company does not have an alternative use and the contract includes an enforceable right to payment in an amount that corresponds directly with the value of the performance completed. To measure progress towards completion on performance obligations for which revenue is recognized over time the Company primarily utilizes an input method based upon a ratio of direct labor hours incurred to date to management’s estimate of the total direct labor hours to be incurred at completion on each contract. Revenue from contracts that is recognized over time accounted for approximately 60% of revenue in fiscal 2021.

We identified revenue associated with in-process contracts recognized over time utilizing an input method as a critical audit matter because of the judgments necessary for management to estimate total direct labor hours at completion. An extensive audit effort and a

high degree of auditor judgment was required when performing audit procedures to audit management’s estimates of total direct labor hours at completion used to recognize revenue over time and evaluating the results of those procedures.

Our audit procedures related to management’s estimate of total direct labor hours at completion included the following, among others:

~~We have audited the internal control over financial reporting of Graham Corporation and subsidiaries (the “Company”) as of March 31, 2019, based on criteria established in~~ ~~Internal Control — Integrated Framework (2013)~~ issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2019, based on criteria established in ~~Internal Control — Integrated Framework (2013)~~ ~~issued by COSO.~~

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended March 31, 2019 of the Company and our report dated May 31, 2019 expressed an unqualified opinion on those consolidated financial statements and included an explanatory paragraph related to the Company’s change in method of accounting for revenue from contracts with customers in fiscal year 2019 due to the adoption of Accounting Standards Update No. 2014-09, ~~Revenue from Contracts with Customers (Topic 606)~~.

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A of its Annual Report on Form 10-K for the year ended March 31, 2019. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

Management, including our President and Chief Executive Officer (principal executive officer) and Vice President-Finance & Administration and Chief Financial Officer (principal financial officer), has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based upon, and as of the date of that evaluation, our President and Chief Executive Officer and Vice President-Finance & Administration and Chief Financial Officer concluded that the disclosure controls and procedures were effective, in all material respects, to ensure that information required to be disclosed in the reports we file and submit under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is (i) recorded, processed, summarized and reported as and when required and (ii) is accumulated and communicated to our management, including our President and Chief Executive Officer and Vice President-Finance & Administration and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

There has been no change to our internal control over financial reporting during the fourth quarter of the fiscal year covered by this Annual Report on Form 10-K that has materially affected, or that is reasonably likely to materially affect our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our administrative, non-production line employees were working remotely during the first quarter of fiscal 2021 due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 pandemic situation on our internal controls to minimize the impact on their design and operating effectiveness.

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our organization have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, 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 controls is also 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 our stated goals under all potential future conditions. Moreover, over time controls 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 the design of an internal control system, misstatements due to error or fraud may occur and not be detected. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Under the supervision and with the participation of management, including our President and Chief Executive Officer (principal executive officer) and Vice President–Finance & Administration and Chief Financial Officer (principal financial officer), we conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework established in Internal Control–Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment under this framework, management concluded that our internal control over financial reporting was effective as of March 31, ~~2019.~~

Deloitte & Touche LLP, the independent registered public accounting firm that audited the consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on our internal control over financial reporting.2021.
