We also manufacture a line of building supply construction weatherization products through our wholly owned subsidiary, Alpha ProTech Engineered Products, Inc. Our products are sold under the Alpha Pro Tech brand name, as well as under private label.

Our products are grouped into threetwo business segments: (1) the Building Supply segment, consisting of construction weatherization products, such as housewrap, housewrap accessories including window and door flashing, and seam tape, and synthetic roof underlayment, as well as other woven material; and (2) the Disposable Protective Apparel segment, consisting of disposable protective apparel, such asgarments (including shoecovers, bouffant caps, gowns, coveralls, lab coats,gowns, frocks and other miscellaneous products; and (3) the Infection Control segment, consisting oflab coats), face masks and eyeface shields. All financial information presented hereinin this report reflects the current segmentation.

STRATEGY

Our principalprincipal strategy focuses on developing, producing and marketing differentiated, innovative high value products that protect people, products and environments. Our key sales growth strategies are based on communicating directly with end users and developing innovative products to suit individual end users’ needs.

Our products are used primarily in cleanrooms, industrial safetysafety manufacturing environments and health care facilities, such as hospitals, laboratories and dental offices, as well as building and re-roofing sites. Our products are distributed principally in the United States of America (“United States” or “U.S.”) through a network consisting of purchasing groups, national distributors, local distributors, independent sales representatives, and our own sales and marketing force.

Building Supply

The Building Supply segment consists of a line of construction supply weatherization products, namely housewrap, housewrap accessories and synthetic roof underlayment, as well as other woven material. This line of products is a natural extension of our core capabilities: creating proprietary products designed to protect people and environments.

The usage of these construction supply weatherization products offers great advantages in decreasing the time that it takes to construct a home, as well as reducing costs.  The housewrap, under the trademark REX™, offers a weather resistant barrier and, to the homeowner, years of lower energy consumption.  REX™REX Wrap® and REX Wrap and REX™ Wrap PlusPlus® are woven and coated polypropylene micro perforated weather resistant barriers, and REX™ Wrap Fortis with JX ALTA 360° Drainage Technology™ is a one-of-a-kind breathable product that uniquely enables the drainage of water in every direction to protect buildings from the elements exponentially better, we believe, than a traditional housewrap, while decreasing job site material waste, simplifying installation to reduce labor and allowing fewer products to be carried onto the job site. Our housewrap accessories includes REXTREME Window and Door Flashing, which provides a tight seal from air and moisture around windows and doors and REX™ Premium Seam Tape which is a high-strength film that helps to seal all seams on housewrap applications.

The proprietary synthetic roof underlayment, REX™ SynFelt, SynFelt®, has the ability to resist the environment, as opposed to conventional organic roofing underlayment that is prone to rapid degradation and mold growth.  We also manufacture and distribute TECHNOply™TECHNOply® and TECHNO™ SB,TECHNO SB®, economy versions of our synthetic roof underlayment, to capture market share in the lower end of the market.

These products are manufactured in our manufacturing facility in Valdosta, Georgia and through our joint venture in India, as described in more detail below under “Manufacturing.”

Disposable Protective Apparel

The Disposable Protective Apparel segment includes many different stylesconsists of a complete line of disposable protective garments (shoecovers, bouffant caps, coveralls, gowns, frocks and lab coats), as well as face masks and face shields.

Our goal in the design and manufacture of all our disposable protective garments is to keep the wearer cool, clean, comfortable and to provide the right level of protection for the wearer and the wearer’s environment.  To achieve this, we offer a comprehensive selection of materials and garment designs to meet a wide range of application requirements. Our materials are clean, durable and offer the wearer a great comfort level. Our products, are offered under proprietary materials such as shoecovers, bouffant caps, gowns, coveralls, lab coats, frocksChemTech®, BarrierTech®, ComforTech®, AlphaGuard® and other miscellaneous products. GenPro®,   UltraGrip™, SafeStep®, MaxGrip®, AquaTrak®, SureGrip®, NuTech® and NaviTrak®.

The vast majority of these productsthe disposable protective garments are manufactured through our joint venture in India, as well as by other subcontractors in Asia and, to a much lesser extent, a subcontractorby other contract manufacturers in Asia and Mexico, as described in more detail below under “Manufacturing.” Certain proprietary products are made using materials supplied by us.

Infection Control

The Infection Control segment includes face masks and eye shields. Our face masks come in a wide variety of filtration efficiencies and styles. Our patented Positive Facial Lock® feature provides a custom fit to the face to prevent blow-by for better protection. The term "blow-by" is used to describe the potential for infectious material to enter or escape a facemaskface mask without going through the filter as a result of gaps or openings in the face mask. Our Magic Arch® feature holds the mask away from the nose and mouth, creating a comfortable breathing chamber. One of our masks that

Our N-95 Particulate Respirator National Institute for Occupational Safety and Health (“NIOSH”) approved face mask, which incorporates both the Positive Facial Lock® feature and the Magic Arch® feature, is the N-95 Particulate Respirator face mask, which was recommended by the Centers for Disease Controlhas historically experienced increased demand during outbreaks of infectious disease, such as SARS in 2003, Bird Flu in 2006, H1N1 in 2009 and Prevention (“CDC”)COVID-19 in 2020, to combat the spread of the H1N1 Influenza A pandemic in 2009.these diseases.

All eye shields are made from an optical-grade polyester film and have a permanent anti-fog feature. This provides the wearer with extremely lightweight, distortion-free protection that can be worn for hours, and the eye shields will not fog up from humidity and/or perspiration. An important feature of all face masks and eye and face shields is that they are disposable, which eliminates the possibility of cross infection between patients and saves users,consumers, such as hospitals, the expense of sterilization after every use.

This segment could experience increased demand during outbreaks of infectious disease, such as H1N1 in 2009 and the Ebola crisis in 2014.

As described in more detail below under “Manufacturing,,” our face masks are primarily manufactured in our facility in Salt Lake City, Utah. Our eye shields are produced in our facility in Nogales, Arizona and assembled by a subcontractor in Mexico.

All of our disposable protective apparel products, including face masks and face shields, are sold through similar distribution channels, are single-use and disposable, have the purpose of protecting people, products and environments, and have to be produced in Food and Drug Administration (“FDA”) approved facilities, regardless of the market served.

The Company’s products are sold under the “Alpha Pro Tech” brand name and under private label, and they are predominantly sold in the U.S.

Financial information related to the threetwo segments can be found in Activity of Business Segments (Note 14)15) of the Notes to Consolidated Financial Statements.

AWorkplace Health and SafetyVAILABLE

The health, safety, and wellness of our employees is a priority in which we have always invested, and will continue to do so.

ItemItem 1A.    RiskRisk Factors.

Making or continuing an investment in common stock issued by the Company involves certain risks that you should carefully consider. The risks and uncertainties described below are not the only risks that may have a material adverse effect on the Company. Additional risks and uncertainties also could adversely affect our business and our results. If any of the following risks actually occur, our business, financial condition and results of operations could be negatively affected, the market price of our common stock could decline and you could lose all or a part of your investment. Further, to the extent that any of the information contained in this Annual Report on Form 10-K constitutes forward-looking statements, the risk factors set forth below also are cautionary statements identifying important factors that could cause the Company’s actual results to differ materially from those expressed in any forward-looking statements made by or on behalf of the Company.

Global economic conditionsRisks Related to the COVID-19 Pandemic

The effects of the COVID-19 pandemic could continue to have a material adverse effect on our business, financial results and results of operations.

The situation relating to the COVID-19 pandemic is complex and still evolving, with a broad number of governmental and commercial efforts to contain the spread of the virus globally. The duration and extent of the impact of the COVID-19 pandemic on our business, operations and financial results depends on factors that cannot be accurately predicted at this time, such as the severity and transmission rate of new variants of the COVID-19 virus, the extent and effectiveness of containment actions, the speed and efficacy of vaccination efforts, and the impact of these and other factors on our employees, customers, industry partners, suppliers and third-party dealers and distributors.

Federal, state and local governments, as well as foreign governments, have imposed numerous protocols and regulations in an effort to limit the spread of the COVID-19. We have implemented a number of measures in an effort to protect our employees’ health and well-being, including having certain office workers work remotely. The potential negative effects to our operations, including reductions in production levels, research and development activities and increased costs resulting from our efforts to mitigate the impact of COVID-19, have adversely affected and may continue to adversely affect our ability to provide our products. Furthermore, the implications of unsuccessfully implementing health and well-being measures, which could, for example, result in workers at our manufacturing facilities testing positive for COVID-19, would also adversely affect our business, including resulting in a product recall. Although we will continue to adhere to restrictions imposed by local governments in the jurisdictions in which we operate, government regulations have impacted workforce availability and expense in certain of the Company’s manufacturing facilities, and we expect this to continue for some time.

Although we have experienced increased sales and significantly increased demand for our PPE products in 2020, the global COVID-19 pandemic had and may continue to have an adverse impact on our manufacturing and distribution capabilities. Disruptions relating to the COVID-19 pandemic, including shelter-in-place orders in the U.S., Mexico, India and other countries, prevented and could again prevent employees, suppliers, distributors and others from accessing manufacturing facilities and from transporting our products or the components required to manufacture our products. For example, the government-mandated closure in India, which started in late March and ended in May 2020, impacted our order fulfillment and revenue growth related to our disposable protective garments. Any government regulation may also impact our ability to supply and ship our products to certain customers, which could lead to cancellation of some orders. Further, worldwide supply chain disruption relating to the COVID-19 pandemic has resulted in product shortages that have impacted and may continue to impact our ability to manufacture our products. We currently utilize third parties to, among other things, manufacture certain components and materials for our products, and to provide services such as sterilization services, and we purchase these materials and services from numerous suppliers worldwide. If either we or any third parties in the supply chain for materials used in the production of our products continue to be adversely impacted by the COVID-19 pandemic, including the restrictions resulting from the COVID-19 pandemic, our supply chain may continue to be disrupted, limiting our ability to manufacture our products. These disruptions may, among other things, continue to impact our ability to produce and supply products in quantities necessary to meet market demand. In addition, we have experienced increases in the costs of materials and supplies and shipping costs due to supply chain disruptions, and expect to continue to see higher costs.

Further, in connection with the COVID-19 pandemic and in an effort to increase the wider availability of needed medical and other supplies and products, we may elect to, or governments may require us to, allocate our products (for example, pursuant to the U.S. Defense Production Act (the “DPA”)) in a way that adversely affects our regular operations and financial results, results in differential treatment of customers and/or adversely affects our reputation and customer relationships. Likewise, suppliers of our raw materials who are subject to requests under the DPA may be unable to fulfill our orders for those raw materials, or such fulfillment could be delayed. In addition, unpredictable increases in demand for certain of our products could, or in some cases may continue to, exceed our capacity to meet such demand, which could adversely affect the Company’s businessour financial results and financial results.customer relationships and result in negative publicity.

UnfavorableAs a result of the COVID-19 pandemic, we experienced a significant increase in orders of our PPE products from both legacy and new customers in 2020, followed by a decline in sales in 2021 for such products.  Because of the uncertainty associated with the pandemic, we may experience additional decreases in sales from certain of these customers at the point at which conditions related to the virus change or improve and demand for these products subsides, which could impact our expectations of future orders and sales.

Moreover, the impacts of the COVID-19 pandemic may exacerbate other pre-existing risks, such as political, regulatory, social, financial, operational and cybersecurity risks, and those associated with global economic conditions, including theany of which could have a material adverse effect on our business.

A prolonged recession could result in decreased revenue, margins and earnings.treatments).

Risks Related to Our Industry

The loss of any large customer or a reduction in orders from any large customer could reduce our net sales and harm our operating results.

Our operating results could be negatively affected by the loss of revenue from one or more large customers. Our customers are not contractually obligated to purchase any fixed quantities of products, and they may stop placing orders with us at any time. We are subject to the risk of losing large customers or incurring significant reductions in sales to these customers.

We rely on suppliers and contractors, and our business could be seriously harmed if these suppliers and contractors are not able to meet our requirements.

We rely on a limited number of suppliers and contractors for the manufacture of our Disposable Protective Apparel and Building Supply segments.products. If we lose the services of these key suppliers and contractors, or if they are not willing or able to satisfy our requirements, finding substitute suppliers or contractors may be time-consuming and would affect our results of operations in the near term. Changes in business conditions, pandemics, wars, including the Russian invasion of Ukraine and world sanctions on Russia, Belarus, and related parties, governmental changes, and other factors beyond our control or which we do not presently anticipate could negatively affect our suppliers and contractors, as well as our ability to receive components.

There are risks associated with international manufacturing that could have a significant effect on our business.

We subcontract the manufacturing of some of our goods to Asia.Asia and Mexico. These goods are manufactured pursuant to our specifications and quality assurance guidelines. Certain proprietary products are being made in Asia using materials supplied by us.

We expect that a significant portion of our product sales will be derived from the sale of products for which we subcontract the manufacturing to Asia, but we cannot be certain that we will be able to maintain such subcontracting at current levels. If our ability to subcontract some of our manufacturing to Asia were to decline significantly, our business, results of operations and financial condition could be materially adversely affected. International manufacturing is subject to a number of risks, including the following:

Our joint venture may present risks that are notonly present when third parties are not involved.

We currently participate in a joint venture in India and may in the future enter into joint ventures with other companies or enterprises in international markets, including joint ventures wherein which we may have a lesser degree of control over the business operations, which may expose us to additional operational, financial, legal or compliance risks. We may be dependent on a joint venture counterparty for product distribution, local market knowledge or other resources. If we are unable to effectively cooperate with joint venture partners, or any joint venture partner fails to meets its obligations under the joint venture arrangement, encounters financial difficulty, or elects to alter, modify or terminate the relationship, we may be unable to achieve our objectives and our results of operations may be negatively impacted thereby.

Our success depends in part on protection of our intellectual property, and our failure to do so could adversely affect our competitive advantage, our brand recognition and our business.

The success and competitiveness of our products depend in part upon our ability to protect our current and future technology, manufacturing processes and brand names, including Alpha Pro Tech, through a combination of patent, trademark, trade secret and unfair competition laws.

We enter into confidentiality and non-disclosure of intellectual property agreements with certain of our employees, consultants and vendors and generally control access to and distribution of our proprietary information. Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use our proprietary information without authorization or to develop similar information independently.

Policing unauthorized use of intellectual property is difficult. The laws of other countries may afford little or no effective protection of our technology. We cannot assure you that the steps taken by us will prevent misappropriation of our technology or that agreements entered into for that purpose will be enforceable. In addition, litigation may be necessary in the future to enforce our intellectual property rights, to protect our trade secrets and to determine the validity and scope of the proprietary rights of others. Litigation may result in substantial costs and diversion of resources, either of which could have a material adverse effect on our business, results of operations and financial condition.

Our industry is highly competitive, which may affect our ability to grow our customer base and generate sales.

The markets for our products are intensely competitive. We currently experience competition from numerous companies in each of the markets in which we participate.

Many of our competitors are more established, benefit from greater market recognition and have substantially greater financial, development, manufacturing and marketing resources than we have.

If we do not compete successfully with respect to these or other companies, it could materially adversely affect our business, results of operations and financial condition.

The Company’s results are affected by competitive conditions and customer preferences.

Demand for the Company’s products, which impacts revenue and profit margins, is affected by (i) the development and timing of the introduction of competitive products; (ii) the Company’s response to downward pricing to stay competitive; (iii) changes in customer order patterns, such as changes in the levels of inventory maintained by customers and the timing of customer purchases; and (iv) changes in customers’ preferences for our products, including the success of products offered by our competitors and changes in customer designs for our competitors’ products that can affect the demand for the Company’s products.

The Company’s growth objectives are largely dependent on the timing and market acceptance of its new product offerings, including its ability to continually renew its pipeline of new products and to bring those products to market.

This ability may be adversely affected by difficulties or delays in product development, such as the inability to identify viable new products, obtain adequate intellectual property protection or gain market acceptance of new products. There are no guarantees that new products will prove to be commercially successful.

Security breaches and other disruptions to the Company’s’s information technology infrastructure could interfere with the Company’sCompany’s operations, compromise information belonging to the Company and itsour customers and suppliers and expose the Company to liability, which could adversely impact the Company’sCompany’s business and reputation.

In the ordinary course of business, the Company relies on information technology networks and systems, some of which are managed by third parties, to process, transmit and store electronic information, and to manage or support a variety of business processes and activities. Additionally, the Company collects and stores sensitive data, including proprietary business information. Despite security measures and business continuity plans, the Company’sCompany’s information technology networks and infrastructure may be vulnerable to damage, disruptions or shutdowns due to attack by hackers, breaches, employee error or malfeasance, power outages, computer viruses, telecommunication or utility failures, systems failures, natural disasters or other catastrophic events. While we have not experienced any material losses related to cyber attackscyber-attacks or information security breaches to date, any and any such event could result in legal claims or proceedings, liability or penalties under privacy laws, disruption in operations and damage to the Company’s reputation, which could adversely affect the Company’s business.

The Company’s’s future results may be affected by various legal and regulatory proceedings and legal compliance risks.

From time to time, the Company is subject to certain legal and regulatory proceedings in the ordinary course of business and otherwise. The outcome of these legal proceedings may differ from the Company’s expectations because the outcomes of litigation, including regulatory matters, are often difficult to reliably predict. Various factors or developments cancould lead the Company to change current estimates of liabilities and related insurance receivables where applicable, or make such estimates for matters previously not susceptible to reasonable estimates, such as a significant judicial ruling or judgment, settlement, regulatory development or change in applicable law. A future adverse ruling, settlement or unfavorable development could result in charges that could have a material adverse effect on the Company’s results of operations or cash flows in any particular period.

Our common stock price is volatile, which could result in substantial losses for individual shareholders.

The market price of our common stock has been volatile, and we expect that it will continue to be volatile. In particular, our common stock may be subject to significant fluctuations in response to a variety of factors, including, but not limited to:including:

Item 3.    Legal Proceedings.

The Company is presently involved in protracted litigation against a competitor in an action styled Alpha Pro Tech, Inc. v. VWR International, LLC, pending in the U.S. District Court for the Eastern District of Pennsylvania, CV 12-1615, wherein the Company originally sought damages for unfair trade practices and false advertising against the competitor, and the competitor counterclaimed asserting similar claims against the Company.  In August of 2017, the court ruled against the Company on its claims against the competitor. The competitor, as the prevailing party with respect to those claims, subsequently filed a motion seeking to recover from the Company an amount in excess of $2 million in attorneys’ fees and costs, which motion was granted by the court. In November of 2017, the Company, in consultation with new litigation counsel, filed a motion to reconsider the attorneys’ fee award. The court heard arguments on the motion to reconsider at a hearing in February of 2018. At the hearing, the court encouraged the parties to attempt to resolve the matter in advance of a ruling on the motion to reconsider. The parties are currently working to schedule a mediation to occur during March of 2018. The Company has accrued in its financial statements an amount that management has determined to be reasonable in anticipation of a resolution of the matter, and management intends to participate in good faith in the mediation to attempt to reach a resolution of the matter that is as favorable to the Company as possible. Regardless of the outcome of the pending mediation or the motion to reconsider, the Company expects that the amount of any attorneys’ fee award will be significantly reduced from what is being requested. The Company is also in the process of evaluating, with current litigation counsel, possible avenues for recovery of any amount ultimately paid by the Company to resolve the matter, including possible claims against former litigation counsel. Any amount that might be recovered in connection with any such claims cannot be reasonably estimated at this time.

The Company is subject to various pending and threatened litigation actions in the ordinary course of business. Although it is not possible to determine with certainty at this point in time what liability, if any, wethe Company will have as a result of such litigation, based on consultation with legal counsel, management does not anticipate that the ultimate liability, if any, resulting from such litigation will have a material effect on ourthe Company’s financial condition and results of operations.

These and many other factors could affect the Company’s future operating results and financial condition and could cause actual results to differ materially from expectations based on forward-looking statements made in this document or elsewhere by the Company or on its behalf.

Special Note Regarding Smaller Reporting Company Status

We are filing this Annual Report on Form 10-K as a “smaller reporting company” (as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended) based on our public float (the aggregate market value of our common equity held by non-affiliates of the Company) as of the last business day of our second fiscal quarter of 2017.2021. As a result of being a smaller reporting company, we are allowed and have elected to omit certain information from this Management’s Discussion and Analysis of Financial Condition and Results of Operations; however, we have provided all information for the periods presented that we believe to be appropriate and necessary to aid in an understanding of the current consolidated financial position, changes in financial position and results of operations of the Company.

Critical Accounting Policies and Estimates

The preparation of our financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of net sales and expenses during the periods reported. We base estimates on past experience and on various other assumptions that are believed to be reasonable under the circumstances. Our estimates are subject to uncertainties associated with the ongoing COVID-19 pandemic. The application of these accounting policies on a consistent basis enables us to provide timely and reliable financial information. Our significant accounting policies and estimates are more fully described in “NoteNote 2 – Summary“Summary of Significant Accounting Policies” in the notes to our consolidated financial statements in Item 8. Our critical accounting policies and estimates include the following:

Accounts Receivable: Accounts receivable are recorded at the invoice amount and do not bear interest. The general terms for receivables is net 30 days.  The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable; however, changes in circumstances relating to accounts receivable may result in a requirement for additional allowances in the future.  The Company determines the allowance based upon historical write-off experience and known conditions about customers’ current ability to pay.  Account balances are charged against the allowance when the potential for recovery is considered remote. For new customers with no order history with the Company we may require advance payments to reduce our credit risk. In 2021 and 2020, we recorded approximately $0 and $2,000, respectively, in charge-offs against the allowance.

Inventories:Inventories:  Inventories include freight-in, materials, labor and overhead costs and are stated at the lower of cost or net realizable value.  Allowances are recorded for slow-moving, obsolete or unusable inventory. We assess our inventory for estimated obsolescence or unmarketable inventory and write down the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future sales and supply on-hand, if necessary. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. In 2021 and 2020, we recorded approximately $376,000 and $114,000, respectively, in write-downs of inventory.

Leases: We determine if an arrangement is a lease at inception. Operating leases are included as right-of-use (“ROU”) assets and lease liabilities on our consolidated balance sheet. ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. Our leases do not provide an implicit rate, and, therefore, we estimate our collateralized borrowing rate under similar terms based on the information available at the commencement date in determining the present value of future minimum lease payments. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options. We do not record leases on our consolidated balance sheet with a term of one year or less. We elected a package of transition practical expedients, which included not reassessing whether any expired or existing contracts are or contain leases, not reassessing the lease classification of expired or existing leases, and not reassessing initial direct costs for existing leases. We also elected a practical expedient to not separate lease and non-lease components. We did not elect the practical expedient to use hindsight in determining our lease terms or assessing impairment of our ROU assets. As of December 31, 2021, we have $2.6 million in ROU assets.

Revenue Recognition:Recognition: ForNet sales transactions,includes revenue from products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Our customer contracts have a single performance obligation: transfer control of products to customers. Revenue is measured as the amount of consideration that we compliedexpect to receive in exchange for transferring control of products. All revenue is recognized when we satisfy our performance obligations under the applicable contract. We recognize revenue in connection with transferring control of the promised products to the customer, with revenue being recognized at the point in time when the customer obtains control of the products, which is generally when title passes to the customer upon delivery to a third party carrier for FOB shipping point arrangements and to the customer for FOB destination arrangements, at which time a receivable is created for the invoice sent to the customer. Shipping and handling activities are performed prior to the customer obtaining control of the goods, and are accounted for as fulfillment activities and are not a promised good or service. Shipping and handling charges billed to customers are included in revenue. Shipping and handling costs, associated with the provisionsdistribution of the SecuritiesCompany’s product to the customers, are recorded in cost of goods sold and Exchange Commission (“SEC”) Staff Accounting Bulletin No. 104, Revenue Recognition, which states that revenue should beare recognized when allcontrol of the following revenue recognition criteria are met: (1) persuasive evidence of an arrangement exists; (2) title transfers andproduct is transferred to the customer, assumeswhich is at the risk of loss; (3)time products are delivered to the selling price is fixed or determinable;third party carrier for FOB shipping point arrangements and (4) collectionto the customer for FOB destination arrangements. We estimate product returns based on historical return rates and estimate rebates based on contractual agreements. Using probability assessments, we estimate sales incentives expected to be paid over the term of the resulting receivable is reasonably assured. These criteriacontract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are satisfiedcollected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from net sales. The Company manufactures certain private label goods for customers and has determined that control does not pass to the customer at the time of manufacture, based upon shipmentthe nature of product,the private labelling. The Company has determined that, as of December 31, 2021, it had no material contract assets, and sales are recognized accordingly.concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. As of December 31, 2021, the Company had no contract liabilities as compared to $209,000 as of December 31, 2020 which contract liabilities were a result of customer advance payments of orders connected to the COVID-19 pandemic (see “Impact of the Novel Coronavirus (COVID-19)” below).

Sales Returns,, Rebates and Allowances:Allowances: Sales are reduced for any anticipated sales returns, rebates and allowances based on historical experience. Since our return policy is only 90 days and our products are not generally susceptible to external factors such as technological obsolescence or significant changes in demand, we are able to make a reasonable estimate for returns. We offer end-user product specific and sales volume rebates to select distributors. Our rebates are based on actual sales and are accrued monthly.

Stock-Based Compensation: The Company accounts for stock-based awards using Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 718, Stock Compensation.(“ASC 718”). ASC 718 requires companies to record compensation expense for the value of all outstanding and unvested share-based payments, including employee stock options and similar awards.

The fair values of stock option grants are determined using the Black-Scholes option-pricing model and are based on the following assumptions: expected stock price volatility based on historical data and management’s expectations of future volatility, risk-free interest rates from published sources, expected term based on historical data, and no dividend yield, as the Board of Directors currently has no plans to pay dividends in the foreseeable future. The Company accounts for option forfeitures as they occur. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and that are fully transferable. In addition, the option-pricing model requires the input of highly subjective assumptions, including expected stock price volatility. Our stock options have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the fair value of such options. In 2021 and 2020, we recorded $315,000 and $375,000, respectively, in compensation expense for share-based awards,

OVERVIEW

Alpha Pro Tech is in the business of protecting people, products and environments. We accomplish this by developing, manufacturing and marketing a line of high-value, disposable protective apparel and infection control products for the cleanroom, industrial, pharmaceutical, medical and dental markets. We also manufacture a line of building supply construction weatherization products. Our products are sold under the Alpha“Alpha Pro TechTech” brand name, as well as under private label.

Our products are grouped into threetwo business segments: (i) the Building Supply segment, consisting of construction weatherization products, such as housewrap and synthetic roof underlayment as well as other woven material; and (ii) the Disposable Protective Apparel segment, consisting of disposable protective apparel, such asgarments (including shoecovers, bouffant caps, gowns, coveralls, lab coats,gowns, frocks and other miscellaneous products; and the Infection Control segment, consisting oflab coats), face masks and eyeface shields. All financial information presented herein reflects the current segmentation.

Our target markets include pharmaceutical manufacturing, bio-pharmaceutical manufacturing and medical device manufacturing, lab animal research, high technology electronics manufacturing (which includes the semi-conductor market), medical and dental distributors, and construction, building supply and roofing distributors.

Our products are used primarily in cleanrooms, industrial safety manufacturing environments, health care facilities, such as hospitals, laboratories and dental offices, and building and re-roofing sites. Our products are distributed principally in the United States through a network consisting of purchasing groups, national distributors, local distributors, independent sales representatives and our own sales and marketing force.

Impact of the Novel Coronavirus (COVID-19)

After the start of the COVID-19 pandemic in early 2020, we experienced a significant surge in customer demand for our proprietary N-95 Particulate Respirator face mask product and other personal protective equipment (“PPE”) products as a result of COVID-19. We experienced a dramatic increase in revenue from sales of PPE products during 2020 and to a lesser extent the beginning of 2021, especially with respect to face masks and disposable protective garments, including shoecovers, coveralls, gowns, lab coats and bouffant caps.

In an effort to meet the unprecedented demand, and to aid communities around the world in responding to the ongoing healthcare crisis, the Company ramped up production during the first quarter of 2020 of our PPE products, in particular our N-95 face mask, which is manufactured by the Company in the United States. We addressed the growing customer demand for PPE products by increasing and improving the human, mechanical, and supply chain components behind production, but even with these increases and improvements, customer demand for PPE products exceeded industry supply from time to time.

Since 2020, we have encountered a number of constraints within our supply chain due to government-mandated shutdowns, raw materials shortages and shipping delays. Although we continue to work to alleviate these supply chain issues by securing additional supply sources, in the event of subsequent shutdowns, shortages or delays, our production and sales could be further impacted. Further, we have experienced increases in the costs of raw materials, and if the prices of raw materials continue to rise more rapidly than our sales prices,  our profits may be impacted negatively.

We are continuing to serve our customers while taking every precaution to provide a safe work environment for our employees. We have enacted enhanced operating protocols to assure the safety and well-being of our employees, and otherwise adjusted work schedules to maximize our capacity while adhering to recommended precautions such as social distancing. We believe that we may have to take further actions that we determine are in the best interests of our employees or as required by federal, state, or local authorities. Although we will continue to adhere to restrictions imposed by local governments in the jurisdictions in which we operate, government regulations have impacted workforce availability and expense in certain of the Company’s manufacturing facilities, and we expect this to continue for some time. While this remains a fluid situation, all of our U.S. manufacturing sites are currently operating at or above normal production rates. 

COVID-19 has resulted in a downturn in the global financial markets and a slowdown in the global economy. This economic environment may impact some of our customers’ ability to pay or lead them to request extended payment terms, and we have experienced cost increases from some of our suppliers.  Additionally, we expect that demand for our Building Supply segment products could be negatively impacted if we experience a decrease in housing starts and increased uncertainty in the housing market and the economy in general, although to date we have not experienced any material negative impact in our Building Supply segment.

The impact of the COVID-19 pandemic continues to unfold. Overall, the increase in sales of our PPE products resulting from the pandemic had a positive impact on our 2020 and 2021 financial results. The extent of the pandemic’s effect on our future operational and financial performance will depend in large part on future developments. Future developments include the duration, scope and severity of the pandemic and new variants, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, and the efficacy of mass vaccinations, and the resumption of widespread economic activity in certain sectors. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, we are unable to predict with any certainty the likely impact of the COVID-19 pandemic on our future operations

Management will continue to carefully monitor the current dynamic market conditions and work to respond to them swiftly and effectively.

RESULTS OF OPERATIONS

The following table sets forth certain operational data as a percentage of sales for the years indicated:

Fiscal Year 20172021 Compared to Fiscal Year 20162020

Sales.Consolidated sales for the year ended December 31, 20172021 decreased to $44,025,000,$68,637,000, from $46,176,000$102,700,000 for the year ended December 31, 2016,2020, representing a decrease of $2,151,000,$34,063,000, or 4.7%33.2%. This decrease consisted of decreased sales in the Building SupplyDisposable Protective Apparel segment of $2,702,000, partially offset by increased sales in the Infection Control segment of $520,000$40,372,000 and increased sales in the Building Supply segment of $6,309,000.

Disposable Protective Apparel Segment

Sales for the Disposable Protective Apparel segment for the year ended December 31, 2021 decreased by $40,372,000, or 56.0%, to $31,748,000, compared to $72,120,000 for 2020. This segment decrease was due to a 3.5% increase in sales of $31,000.disposable protective garments, an 80.0% decrease in sales of face masks and a 68.0% decrease in sales of face shields, all primarily due to reduced customer demand in 2021 compared to a surge in demand in 2020 associated with the pandemic.

The sales mix of the Disposable Protective Apparel segment for the year ended December 31, 2021 was approximately 63% for disposable protective garments, 26% for face masks and 11% for face shields. This sales mix is compared to approximately 27% for disposable protective garments, 58% for face masks and 15% for face shields for the year ended December 31, 2020.

Sales for the disposable protective garments increased by 3.5% in 2021, primarily due to record sales in the first and second quarters of 2021 resulting from strong orders received from our major international channel partner in 2020 in response to COVID-19. Sales in the second half of 2021 were negatively affected as inventory levels in the supply chain primarily with our partner mentioned above, were higher than historical. Although sales were down in the latter half of 2021 and more in line with pre-pandemic levels, this partner’s sales to its end users for the same period are much higher than pre-pandemic levels.

The decrease in face mask sales in 2021, primarily our proprietary N-95 Particulate Respirator face mask, resulted from very significant record breaking customer demand associated with the COVID-19 pandemic in 2020. The decrease in face shield sales in 2021 was also due to the decline in demand associated with the COVID-19 pandemic. Although face mask and face shield sales were down in 2021, they were higher than any other year on record, with the exception of the past pandemics in 2020 (COVID-19) and 2009 (H1N1). Due to COVID-19 variants and other challenges related to efforts to reduce the duration, scope and severity of the pandemic, sales of face masks and face shields are expected to remain higher than pre-pandemic levels in the short term, but it is uncertain how long this will continue.

As the pandemic continues, our partnerships within our authorized distributor community in this segment remains strong.  Together, we are navigating what is still a delicate balance of in-person and virtual opportunities to market our disposable protective garments, face mask and face shield portfolio to current and new end-customers.  Additionally, we are working to support our end-customers in concert with our distributor partners until such time that the pandemic is behind us, whether it be through virtual selling and product training, practical face-to-face meetings  or via small off-campus gatherings.

Building Supply Segment

Building Supply segment sales for the year ended December 31, 2017 decreased2021 increased by $2,702,000,$6,309,000, or 9.9%20.6%, to $24,641,000,a record $36,889,000, compared to $27,343,000$30,580,000 for 2016. Thisthe year ended December 31, 2020. The Building Supply segment decreaseincrease was primarily due to a 23.4% decreasean increase in sales of synthetic roof underlayment (including REX™of 25.9%, TECHNOply™ and our new TECHNO SB®), partially offset by an 8.2% increase in sales of housewrap and a 38.7% increase inaccessories of 19.7% and flat sales of other woven material. material compared to 2020.

The sales mix of the Building Supply segment for the year ended December 31, 20172021 was approximately 50% for synthetic roof underlayment, 41%43% for housewrap and 9%accessories and 7% for other woven material. This compared to 51%approximately 48% for synthetic roof underlayment, 41%43% for housewrap and 8%accessories and 9% for other woven material for the year ended December 31, 2016.

Although2020. Our synthetic roof underlayment product line includes REX SynFelt®, REX TECHNOply® and TECHNO SB®; our housewrap product line consists of REX Wrap®, REX Wrap® Plus and REX Wrap Fortis®; and our housewrap accessories product line consists of REXTREME Window and Door Flashing and REX™ Seam tape.

Building Supply segment sales were down, housewrap sales remained strong,a record for the year ended December of 2021, with increased sales in 2017 of 8.2%. At the end of the third quarter, we announced a new, innovative and exciting product line to our housewrap family, REX™ Wrap Fortis with JX ALTA 360° Drainage Technology™. With its one-of-a-kind construction, this product uniquely enables the drainage of water in every direction to protect buildings from the elements exponentially better, we believe than a traditional housewrap, while decreasing job site material waste, simplifying installation to reduce labor and allowing fewer products to be carried onto the job site. This new product offering is now competing in a segment of the housewrap market that has historically been is currently untapped for us, and we anticipate that it will provide us withcontinued significant growth opportunities going forward.

due to strong demand for both our synthetic roof underlayment and housewrap products.

The adoption of this guidance also increased the number of dilutive shares because excess tax benefits are no longer included in the assumed proceeds when calculating the number of dilutive shares. In addition, the effective tax rate will be reduced in future periods when there are excess tax benefits from stock options exercised.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses Topic 326, which requires entities to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowances for losses. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within that year. Early adoption is permitted.
