(&#8220;Alpha Pro Tech,&#8221; the &#8220;Company,&#8221; &#8220;we&#8221;, &#8220;us&#8221; or &#8220;our&#8221;) is in the business of protecting people, products and environments. The Company accomplishes this by developing, manufacturing and marketing a line of building supply products for the new home and re-roofing markets and a line of disposable protective apparel for the cleanroom, industrial, pharmaceutical, medical and dental markets.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;">The Building Supply segment consists of construction weatherization products, such as housewrap and synthetic roof underlayment, as well as other woven material.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;">The Disposable Protective Apparel segment consists of a complete line of disposable protective clothing (shoecovers, bouffant caps, coveralls, gowns, frocks and lab coats), face masks and face shields. 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 (&#8220;FDA&#8221;) approved facilities, regardless of the market served.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;">The Company&#8217;s products are sold under the "Alpha Pro Tech" brand name as well as under private label, and are predominantly sold in the United States of America (&#8220;US&#8221;).</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 21pt;">The ongoing&nbsp;novel coronavirus (COVID-19) pandemic has adversely affected global economies, financial markets and the overall environment in which we do business. Overall, the increase in sales of our Disposable Protective Apparel segment products resulting from the pandemic has had a positive impact on our year-to-date results, but the positive impact in 2021 is less than in 2020, as the effects of COVID-19 are normalizing. The extent of the pandemic&#8217;s effect on our future operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, 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&nbsp;COVID-19 pandemic on our future operations.</p>

Our customer contracts have a single performance obligation: transfer control of products to customers. Revenue is measured as the amount of consideration that we expect 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 distribution of the Company&#8217;s product to the customers, are recorded in cost of goods sold and are recognized when control of the product is transferred to the customer, 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. 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 contract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are collected 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 the nature of the private labelling. The Company has determined as of March 31, 2021 that it had no material contract assets, and concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. As of March 31, 2021, we had contract liabilities of $113,000 as a result of customer advance payments of orders in connection with the COVID-19 pandemic. See Note 10 and Note 11 of these Notes to Condensed Consolidated Financial Statements (Unaudited) for information on revenue disaggregated by type and by geographic region.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;">The Company maintains a stock option plan (the &#8220;2004 Option Plan&#8221;) under which the Company may grant incentive stock options and non-qualified stock options to employees and non-employee directors. Stock options have been granted with exercise prices at or above the fair market value of the underlying shares of common stock on the date of grant. Options vest and expire according to terms established at the grant date.</p>

Although no new awards may be granted under the 2004 Option Plan, all previously granted awards under the 2004 Option Plan will continue to be governed by the terms of the 2004 Option Plan. As of March 31, 2021, 8,912 restricted stock equity awards had been granted under the 2020 Incentive Plan.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 21pt;">For the three months ended March 31, 2021 and 2020, no stock options were granted under the Company&#8217;s 2004 Option Plan. The Company recognized $74,000 and $91,000 in stock-based compensation expense for the three months ended March 31, 2021 and 2020, respectively, related to outstanding options.&nbsp; For the three months ended March 31, 2021 and 2020 no restricted stock equity awards were granted under the 2020 Incentive Plan.

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 18pt;">The Company uses the Black-Scholes option-pricing model to value the options. The Company uses historical data to estimate the expected life of the options.&nbsp; The risk-free interest rate for periods within the contractual life of an award is based on the US Treasury yield curve in effect at the time of grant. The estimated volatility is based on historical volatility and management&#8217;s expectations of future volatility. The Company uses an estimated dividend payout of zero, as the Company has not paid dividends in the past and, at this time, does not expect to do so in the future. The Company accounts for option forfeitures as they occur. The following table summarizes stock option activity for the three months ended March 31, 2021:</p>

ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. ASU 2016-13 is effective for public companies for the annual periods, including interim periods within those annual periods, beginning after December 15, 2019. This guidance was applicable to the Company&#8217;s fiscal year beginning January 1, 2020. Adoption of the new standard did not have a material impact on our consolidated financial statements.</p>

This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted.

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 23pt;">In 2005, Alpha ProTech Engineered Products, Inc. (a subsidiary of Alpha Pro Tech, Ltd.) entered into a joint venture with a manufacturer in India, Maple Industries and associates, for the production of building products. Under the terms of the joint venture agreement, a private company, Harmony Plastics Private Limited (&#8220;Harmony&#8221;), was created with ownership interests of 41.66% owned by Alpha ProTech Engineered Products, Inc. and 58.34% owned by Maple Industries and associates.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 23pt;">This joint venture positions Alpha ProTech Engineered Products, Inc. to respond to current and expected increased product demand for housewrap and synthetic roof underlayment and provides future capacity for sales of specialty roofing component products and custom products for industrial applications requiring high quality extrusion coated fabrics. In addition, the joint venture now supplies products for the Disposable Protective Apparel segment.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 23pt;">The capital from the initial funding and a bank loan, which loan is guaranteed exclusively by the individual shareholders of Maple Industries and associates and collateralized by the assets of Harmony, were utilized to purchase the original manufacturing facility in India. Harmony currently has four facilities in India (three owned and one rented), consisting of: (1) a 113,000 square foot building for manufacturing building products; (2) a 73,000 square foot building for manufacturing coated material and sewing proprietary disposable protective apparel; (3) a 16,000 square foot facility for sewing proprietary disposable protective apparel; and (4) a 93,000 square foot facility (rented) for manufacturing Building Supply segment products. All additions have been financed by Harmony with no guarantees from the Company.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;">In accordance with ASC 810, Consolidation, the Company assesses whether or not related entities are variable interest entities (&#8220;VIEs&#8221;). For those related entities that qualify as VIEs, ASC 810 requires the Company to determine whether or not the Company is the primary beneficiary of the VIE, and, if so, to consolidate the VIE.

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;">The Company accounts for income taxes using the asset and liability method. A valuation allowance is recorded to reduce the carrying amounts of deferred income tax assets unless it is more likely than not that such assets will be realized. The Company&#8217;s policy is to record any interest and penalties assessed by the Internal Revenue Service as a component of the provision for income taxes. The Company provides allowances for uncertain income tax positions when it is more likely than not that the position will not be sustained upon examination by the tax authority.&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;">An employer generally does not claim a corporate income tax deduction (which would be in an amount equal to the amount of income recognized by the employee) upon the exercise of its employee's incentive stock options (&#8220;ISOs&#8221;) unless the employee does not meet the holding period requirements and sells early, making a disqualifying disposition, or if the options otherwise do not qualify as ISOs under applicable tax laws. With non-qualified stock options (&#8220;NQSOs&#8221;), on the other hand, the employer is typically eligible to claim a deduction upon its employee's exercise of the NQSOs.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 18pt;">On March 27, 2020, President Trump signed into U.S. federal law the Coronavirus Aid, Relief, and Economic Security Act (the &#8220;CARES Act&#8221;), which is aimed at providing emergency assistance and health care for individuals, families and businesses affected by the COVID-19 pandemic and generally supporting the U.S. economy. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act currently has minimal impact on the Company.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Critical Accounting Policies and Estimates</b></p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The preparation of our financial statements in conformity with U.S. generally accepted accounting principles (&#8220;U.S. GAAP&#8221;) 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 Note 2, &#8220;Summary of Significant Accounting Policies&#8221; in the notes to our consolidated financial statements in Item 8 of the 2020 Form 10-K. Our critical accounting policies and estimates include the following:</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Accounts Receivable</b>: Accounts receivable are recorded at the invoice amount and do not bear interest. The general terms for receivables is net 30 days.&nbsp; The allowance for doubtful accounts is the Company&#8217;s best estimate of the amount of probable credit losses in the Company&#8217;s existing accounts receivable; however, changes in circumstances relating to accounts receivable may result in a requirement for additional allowances in the future.&nbsp; The Company determines the allowance based upon historical write-off experience and known conditions about customers&#8217; current ability to pay.&nbsp; 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Inventories:</b> 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Leases:</b> We determine if an arrangement is a lease at inception. Operating leases are included as right-of-use (&#8220;ROU&#8221;) 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.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Revenue Recognition:</b> Net sales 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 expect 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 distribution of the Company&#8217;s product to the customers, are recorded in cost of goods sold and are recognized when control of the product is transferred to the customer, which is at the time products are delivered to the third party carrier for FOB shipping point arrangements and to 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 contract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are collected 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 the nature of the private labelling. The Company has determined that, as of March 31, 2021, it had no material contract assets, and concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. As of March 31, 2021, the Company had contract liabilities of $113,000 as a result of customer advance payments of orders connected to the COVID-19 pandemic (see &#8220;Impact of the Novel Coronavirus (COVID-19)&#8221; below).</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Sales Returns, Rebates and Allowances:</b> 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Stock-Based Compensation:</b> The Company accounts for stock-based awards using Financial Accounting Standards Board (&#8220;FASB&#8221;) Accounting Standards Codification (&#8220;ASC&#8221;) 718, Stock Compensation. 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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&#8217;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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 5pt;">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 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 Pro Tech" brand name, as well as under private label.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 5pt;">Our products are grouped into two business segments: the Building Supply segment, consisting of construction weatherization products, such as housewrap and synthetic roof underlayment as well as other woven material; and the Disposable Protective Apparel segment, consisting of disposable protective garments (including shoecovers, bouffant caps, coveralls, gowns, frocks and lab coats), face masks and face shields. All financial information presented in this report reflects the current segmentation.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 5pt;">Our target markets include pharmaceutical manufacturing, bio-pharmaceutical manufacturing, 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 5pt;">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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 5pt;"><b>Impact of the Novel Coronavirus (COVID-19) </b></p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">In March 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic. COVID-19 continues to spread throughout the U.S. and the world and has resulted in authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. COVID-19 has had, and we expect the virus to continue to have, a number of effects, both positive and negative, on our business operations and financial condition.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Since the start of the COVID-19 pandemic, we experienced a significant surge in customer demand for our proprietary N-95 Particulate Respirator face mask product and other personal protective equipment (&#8220;PPE&#8221;) products as a result of COVID-19. We experienced a dramatic increase in revenue from sales of PPE products during the year of 2020, especially with respect to face masks, face shields and disposable protective garments, including shoecovers, coveralls, gowns, lab coats and bouffant caps.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">During 2020, we encountered a number of constraints within our supply chain due to government-mandated shutdowns, raw materials shortages and shipping delays. Although we worked 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 expect that prices of raw materials may rise more rapidly in the current environment than our sales prices, which could decrease our profits.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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, placed restrictions on non-essential travel, 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&#8217;s manufacturing facilities, and we expect this to continue for some time.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">As detailed below under &#8220;Results of Operations,&#8221; we witnessed a softening in the demand for our N-95 particulate respirator face mask during the first quarter of 2021 and expect sales will decline to be more in-line with pre-pandemic levels in future periods. We expect growth in pre-pandemic demand for our disposable protective garments and continued growth in Building Supply segment products, although this demand could be negatively impacted if we experience a decrease in housing starts and increased uncertainty in the housing market and the economy in general.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The impact of the COVID-19 pandemic continues to unfold. The extent of the pandemic&#8217;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&nbsp;COVID-19 pandemic on our future operations.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Management will continue to carefully monitor the current dynamic market conditions and work to respond to them swiftly and effectively.</p>

This segment increase was due to a 40.7% increase in sales of disposable protective garments, 24.0% increase in sales of face masks and a 93.6% increase in face shields. The increases for face masks, face shields and to a lesser extent disposable protective garments were primarily due to increased demand resulting from the COVID-19 pandemic. The sales mix of the Disposable Protective Apparel segment for the three months ended March 31, 2021 was approximately 45% for disposable protective garments, 38% for face masks and 17% for face shields. This sales mix is compared to approximately 45% for disposable apparel garments, 43% for face masks and 12% for face shields for the three months ended March 31, 2020.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Sales for the disposable protective garments in the first quarter of 2021 were a record and up a very strong 40.7%. This was as a result of strong open orders, primarily from our major international channel partner. We continue to realize higher than historical open orders for disposable protective garments and are working closely with all our channel partners uncovering new end-customer sales opportunities.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The increase in face mask sales of 24.0% was primarily attributable to sales of our proprietary N-95 Particulate Respirator face mask resulting from customer demand associated with the COVID-19 pandemic. Although we showed face mask revenue growth in the first quarter of 2021, sales were materially lower than prior pandemic quarters. We are witnessing a softening in demand due various factors such as: (i) decreased demand from distributors and their customers in light of high levels of stockpiled inventory, resulting from a rush to obtain face masks in the early months of the pandemic, (ii) increased availability of N-95 face masks from manufacturers ramping up production capacity, (iii) increased competition as more manufacturers entered the market as well as Emergency Use Authorization in the U.S. that has allowed foreign manufactured, non-NIOSH approved KN-95 face masks, and (iv) the improvement in outlook with respect to the pandemic and the growing number of individuals being vaccinated to protect against COVID-19. Management expects sales of face mask will decline to be more in-line with pre-pandemic levels in future periods.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The increase in face shield sales of 93.6% was also attributable to the pandemic and resulted in demand primarily from one distributor. Management expect sales of face shields to decrease in the coming quarters and to be more in-line with pre-pandemic levels.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Building Supply segment sales for the three months ended March 31, 2021 increased by $783,000, or 10.4%, to a first quarter record of $8,340,000, compared to $7,557,000 for the three months ended March 31, 2020. The Building Supply segment increase was primarily due to an 18.2% increase in our core building products, including an increase in sales of synthetic roof underlayment of 31.6% and an increase in sales of housewrap of 4.1% compared to the same period of 2020. Sales of other woven material decreased by 26.1% compared to the same period of 2020.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The sales mix of the Building Supply segment for the three months ended March 31, 2021 was approximately 52% for synthetic roof underlayment, 41% for housewrap and 7% for other woven material. This compared to approximately 45% for synthetic roof underlayment, 45% for housewrap and 10% for other woven material for the three months ended March 31, 2020. Our synthetic roof underlayment product line includes REX SynFelt&#174;, REX TECHNOply&#174; and TECHNO SB&#174;, and our housewrap product line consists of REX Wrap&#174;, REX Wrap&#174; Plus and REX Wrap Fortis&#174;.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Open orders for our core building products, consisting of synthetic roof underlayment and housewrap, continue to be at unprecedented levels as the new home construction and residential re-roofing markets were strong in the first quarter of 2021 and optimism remains high going into the second quarter. Our line of synthetic roof underlayment enjoyed strong growth of 31.6% related to these two factors and our housewrap continued growth in the new home construction market. Management is optimistic about continued growth in this segment and has committed to increasing production capacity of this segment by investing approximately $4.0 million in new equipment, which is expected to be operational later in the year.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Gross Profit.</b> Gross profit increased by $625,000, or 7.3%, to $9,179,000 for the three months ended March 31, 2021, from $8,554,000 for the three months ended March 31, 2020. The gross profit margin was 39.6% for the three months ended March 31, 2021, compared to 47.1% for the three months ended March 31, 2020. The gross profit margin on our face masks, in particular our N-95 Particulate Respirator face mask, and face shields, which have a higher gross profit margin than our other products, were negatively impacted in the first quarter of 2021 by a change in distribution channels associated with the pandemic, including higher sales to our legacy distribution channel partners as compared to newer COVID-19 based customers. In addition, our portfolio of products, as well as a spectrum of industries worldwide, have been affected by increases in raw material costs, as well as significant increases in ocean freight and other transportation costs.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Management believes that gross profit margin will be negatively affected in 2021 as a result of changes in product mix as the need for face masks and face shields declines from the surge in customer demand in 2020 as a result of the COVID-19 pandemic. As discussed above, we expect increases in raw material costs, resin in particular, which is a base component material in our disposable protective garments and building products, as well as increases in ocean freight and other transportation costs. In the current environment, cost increases may rise more rapidly than our sales prices, which could decrease gross profit.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Selling, General and Administrative Expenses.</b> Selling, general and administrative expenses increased by $476,000, or 11.6%, to $4,578,000 for the three months ended March 31, 2021, from $4,102,000 for the three months ended March 31, 2020. However, as a percentage of net sales, selling, general and administrative expenses decreased to 19.8% three months ended March 31, 2021, down from 22.6% for the same period of 2020, primarily as a result of the growth in net sales.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The change in expenses by segment for the three months ended March 31, 2021 was as follows: Disposable Protective Apparel was up $425,000, or 33.8%; Building Supply was down $9,000, or 0.6%; and corporate unallocated expenses were up $60,000, or 4.0%. The increase in the Disposable Protective Apparel segment expenses was related to increased employee compensation, insurance and general office expenses, partially offset by decreased travel expenses. The decrease in the Building Supply segment expenses was related to decreased marketing and travel expenses, partially offset by increased employee compensation and increased insurance costs. The increase in corporate unallocated expenses was primarily due to increased public company expenses and increased insurance and general office expenses, partially offset by lower employee compensation and decreased professional fees.</p>

The increased income from operations was primarily due to an increase in gross profit of $625,000, partially offset by an increase in selling, general and administrative expenses of $476,000 and an increase in depreciation and amortization expense of $16,000.

This increase in income before provision for income taxes was due to an increase in income from operations of $133,000 and an increase in other income of $279,000.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;"><b>Provision (Benefit) for Income Taxes</b>. The provision for income taxes for the three months ended March 31, 2021 was $1,007,000, compared to a tax benefit $1,028,000 for the same period of 2020. In the first quarter of 2020, the benefit for income taxes consisted of an estimated nonrecurring tax benefit of approximately $2.0 million as a result of the exercise of disqualified incentive stock options (&#8220;ISOs&#8221;) and the exercise of non-qualified stock options (&#8220;NQSOs&#8221;), partially offset by an estimated tax expense of approximately $1.0 million. The estimated effective tax rate was 21.3% for the three months ended March 31, 2021, compared to negative 23.8% for the three months ended March 31, 2020. Excluding the estimated nonrecurring tax benefit of $2.0 million, the estimated effective tax rate was 22.5% for the three months ended March 31, 2020. The Company does not record a tax provision on equity in income of unconsolidated affiliate, which reduces the effective tax rate.</p>

As mentioned above, a tax benefit from stock options exercised positively impacted net income by an estimated $2.0 million in the first quarter of 2020. Excluding the tax benefit in 2020, net income for the three months ended March 31, 2021 would have exceeded net income for the three months ended March 31, 2020. Net income as a percentage of net sales for the three months ended March 31, 2021 was 16.1%, and net income as a percentage of net sales for the same period of 2020 was 29.4%. Basic earnings per common share for the three months ended March 31, 2021, and 2020 were $0.28 and $0.41, respectively. Diluted earnings per common share for the three months ended March 31, 2021 and 2020 were $0.27 and $0.39, respectively.

The decrease in accounts receivable was related to decreased sales as compared to the fourth quarter of 2020.

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">In February 2016, the FASB issued ASU 2016-02, Leases, which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The update is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those reporting periods, with early adoption permitted. The original guidance required application on a modified retrospective basis with the earliest period presented. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842, which includes an option to not restate comparative periods in transition and elect to use the effective date of ASC 842, Leases, as the date of initial application of transition. Based on the effective date, we adopted this ASU beginning on January 1, 2019 and elected the transition option provided under ASU 2018-11. This standard had a material effect on our consolidated balance sheet with the recognition of new right-of-use assets and lease liabilities for all operating leases, as these leases typically have a non-cancelable lease term of greater than one year. Upon adoption, both assets and liabilities on our consolidated balance sheet increased by approximately $3,455,000. 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 the lease terms or assessing impairment of the ROU assets. See also Note 12 of these Notes to Condensed Consolidated Financial Statements for more information.</p>

ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. ASU 2016-13 is effective for public entities for the annual periods, including interim periods within those annual periods, beginning after December 15, 2019. This guidance is applicable to the Company&#8217;s fiscal year beginning January 1, 2020. Adoption of the new standard did not have a material impact on our consolidated financial statements.</p>

This ASU is intended to simplify aspects of share-based compensation issued to non-employees by making the guidance consistent with accounting for employee share-based compensation. ASU 2018-07 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, with early adoption permitted but no earlier than an entity&#8217;s adoption date of ASC Topic 606 - Revenue form Contracts with Customers. The new guidance is required to be applied retrospectively with the cumulative effect recognized at the date of initial application. We adopted the provisions of this ASU in the first quarter of 2019. Adoption of the new standard did not have a material impact on our consolidated financial statements.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><b>The effects of the COVID-19 pandemic have had, and could continue to have, a material adverse effect on our business, financial results and results of operations. </b></p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">In December 2019, COVID-19 surfaced in Wuhan, China, and the World Health Organization characterized COVID-19 as a pandemic on March 11, 2020. 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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&#8217; health and well-being, including having certain office workers work remotely and suspending employee travel. 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, may 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&#8217;s manufacturing facilities, and we expect this to continue for some time.</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Although we have experienced increased sales and significantly increased demand for our PPE products, the global COVID-19 pandemic has 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, have 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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 &#8220;DPA&#8221;)) 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 our financial results and customer relationships and result in negative publicity.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">As a result of the COVID-19 pandemic, in 2020 we experienced a significant increase in orders of our PPE products from both legacy and new customers. In 2021 we experienced a softening in demand due to various factors, including decreased demand from distributors and their customers in light of high levels of stockpiled inventory, and increased competition, among other factors. Because of the uncertainty associated with the pandemic, we may experience a further decrease in sales as conditions related to the virus change or improve and demand for these products subsides, which could impact our expectations of future orders and sales. 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&#8217; ability to pay or lead them to request extended payment terms, and we have experienced and may continue to experience cost increases from some of our suppliers. Additionally, increased uncertainty in the housing market could negatively impact demand for our Building Supply segment products.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">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, any of which could have a material adverse effect on our business.</p>

As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021, &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;8,912&lt;/div&gt; restricted stock equity awards had been granted under the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; Incentive Plan.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 21pt;"&gt;The Company records compensation expense for the fair value of stock-based awards determined as of the grant date, including employee stock options and restricted stock awards over the determined requisite service period, which is generally ratably over the vesting term.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 21pt;"&gt;For the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt;&lt;/div&gt; stock options were granted under the Company's &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2004&lt;/div&gt; Option Plan.

The Company recognized &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$27,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$0&lt;/div&gt; in compensation expense associated with restricted stock awards for the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&lt;/div&gt; respectively.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 18pt;"&gt;The Company uses the Black-Scholes option-pricing model to value the options. The Company uses historical data to estimate the expected life of the options.&amp;nbsp; The risk-free interest rate for periods within the contractual life of an award is based on the US Treasury yield curve in effect at the time of grant. The estimated volatility is based on historical volatility and management's expectations of future volatility. The Company uses an estimated dividend payout of zero, as the Company has &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; paid dividends in the past and, at this time, does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; expect to do so in the future. The Company accounts for option forfeitures as they occur. The following table summarizes stock option activity for the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic;

Under the terms of the joint venture agreement, a private company, Harmony Plastics Private Limited (&amp;#x201c;Harmony&amp;#x201d;), was created with ownership interests of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;41.66%&lt;/div&gt; owned by Alpha ProTech Engineered Products, Inc. and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;58.34%&lt;/div&gt; owned by Maple Industries and associates.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 23pt;"&gt;This joint venture positions Alpha ProTech Engineered Products, Inc. to respond to current and expected increased product demand for housewrap and synthetic roof underlayment and provides future capacity for sales of specialty roofing component products and custom products for industrial applications requiring high quality extrusion coated fabrics. In addition, the joint venture now supplies products for the Disposable Protective Apparel segment.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 23pt;"&gt;The capital from the initial funding and a bank loan, which loan is guaranteed exclusively by the individual shareholders of Maple Industries and associates and collateralized by the assets of Harmony, were utilized to purchase the original manufacturing facility in India.

For those related entities that qualify as VIEs, ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;810&lt;/div&gt; requires the Company to determine whether or &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; the Company is the primary beneficiary of the VIE, and, if so, to consolidate the VIE. The Company has determined that Harmony is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; a VIE and is, therefore, considered to be an unconsolidated affiliate.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;"&gt;The Company records its investment in Harmony as &amp;#x201c;equity investment in unconsolidated affiliate&amp;#x201d; in the accompanying condensed consolidated balance sheets. The Company records its equity interest in Harmony's results of operations as &amp;#x201c;equity in income of unconsolidated affiliate&amp;#x201d; in the accompanying condensed consolidated statements of income. The Company periodically reviews its investment in Harmony for impairment. Management has determined that &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt;&lt;/div&gt; impairment was required as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021 &lt;/div&gt;or &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; December 31, 2020.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin: 0pt; text-align: left"&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;"&gt;For the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&lt;/div&gt; Alpha Pro Tech purchased &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$6,354,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$4,705,000&lt;/div&gt; of inventories, respectively, from Harmony.

The Company provides allowances for uncertain income tax positions when it is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; that the position will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be sustained upon examination by the tax authority.&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;Alpha Pro Tech, Ltd. and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;An employer generally does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; claim a corporate income tax deduction (which would be in an amount equal to the amount of income recognized by the employee) upon the exercise of its employee's incentive stock options (&amp;#x201c;ISOs&amp;#x201d;) unless the employee does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; meet the holding period requirements and sells early, making a disqualifying disposition, or if the options otherwise do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; qualify as ISOs under applicable tax laws. With non-qualified stock options (&amp;#x201c;NQSOs&amp;#x201d;), on the other hand, the employer is typically eligible to claim a deduction upon its employee's exercise of the NQSOs.&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;The Company had an estimated nonrecurring tax benefit of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$2.0&lt;/div&gt; million in the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; quarter of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; as a result of the exercise of disqualified ISOs and the exercise of NQSOs, partially offset by estimated tax expense of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1.0&lt;/div&gt; million.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 18pt;"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 27, 2020, &lt;/div&gt;President Trump signed into U.S. federal law the Coronavirus Aid, Relief, and Economic Security Act (the &amp;#x201c;CARES Act&amp;#x201d;), which is aimed at providing emergency assistance and health care for individuals, families and businesses affected by the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic and generally supporting the U.S. economy. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act currently has minimal impact on the Company.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

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 (&amp;#x201c;FDA&amp;#x201d;) approved facilities, regardless of the market served.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 21pt;"&gt;The Company's products are sold under the "Alpha Pro Tech" brand name as well as under private label, and are predominantly sold in the United States of America (&amp;#x201c;US&amp;#x201d;).&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family: Times New Roman; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt 0pt 0pt 21pt;"&gt;The ongoing&amp;nbsp;novel coronavirus (COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt;) pandemic has adversely affected global economies, financial markets and the overall environment in which we do business. Overall, the increase in sales of our Disposable Protective Apparel segment products resulting from the pandemic has had a positive impact on our year-to-date results, but the positive impact in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021&lt;/div&gt; is less than in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&lt;/div&gt; as the effects of COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; are normalizing. The extent of the pandemic's effect on our future operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, 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&amp;nbsp;COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic on our future operations.&lt;/div&gt;&lt;/div&gt;</us-gaap:NatureOfOperations>

The condensed consolidated balance sheet as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; December 31, 2020 &lt;/div&gt;was prepared using information from the audited consolidated balance sheet contained in the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; Form &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-K; however, it does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; include all disclosures required by U.S. GAAP for annual consolidated financial statements.&lt;/div&gt; &lt;div style=" font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 18pt;"&gt;Net sales 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 expect 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 &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;third&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; a promised good or service. Shipping and handling charges billed to customers are included in revenue. Shipping and handling costs, associated with the distribution of the Company's product to the customers, are recorded in cost of goods sold and are recognized when control of the product is transferred to the customer, which is generally when title passes to the customer upon delivery to a &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;third&lt;/div&gt; party carrier for FOB shipping point arrangements and to 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 contract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are collected 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 &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; pass to the customer at the time of manufacture, based upon the nature of the private labelling. The Company has determined as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021 &lt;/div&gt;that it had &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; material contract assets, and concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 31, 2021, &lt;/div&gt;we had contract liabilities of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$113,000&lt;/div&gt; as a result of customer advance payments of orders in connection with the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic. See Note &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt; and Note &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;11&lt;/div&gt; of these Notes to Condensed Consolidated Financial Statements (Unaudited) for information on revenue disaggregated by type and by geographic region.&lt;/div&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

Our customer contracts have a single performance obligation: transfer control of products to customers. Revenue is measured as the amount of consideration that we expect 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 <div style="display: inline; font-style: italic; font: inherit;">third</div> 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 <div style="display: inline; font-style: italic; font: inherit;">not</div> a promised good or service. Shipping and handling charges billed to customers are included in revenue. Shipping and handling costs, associated with the distribution of the Company's product to the customers, are recorded in cost of goods sold and are recognized when control of the product is transferred to the customer, which is generally when title passes to the customer upon delivery to a <div style="display: inline; font-style: italic; font: inherit;">third</div> party carrier for FOB shipping point arrangements and to 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 contract. Sales taxes and value added taxes in foreign and domestic jurisdictions that are collected 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 <div style="display: inline; font-style: italic; font: inherit;">not</div> pass to the customer at the time of manufacture, based upon the nature of the private labelling. The Company has determined as of <div style="display: inline; font-style: italic; font: inherit;"> March 31, 2021 </div>that it had <div style="display: inline; font-style: italic; font: inherit;">no</div> material contract assets, and concluded that its contract liabilities (primarily rebates) had the right of offset against customer receivables. As of <div style="display: inline; font-style: italic; font: inherit;"> March 31, 2021, </div>we had contract liabilities of <div style="display: inline; font-style: italic; font: inherit;">$113,000</div> as a result of customer advance payments of orders in connection with the COVID-<div style="display: inline; font-style: italic; font: inherit;">19</div> pandemic. See Note <div style="display: inline; font-style: italic; font: inherit;">10</div> and Note <div style="display: inline; font-style: italic; font: inherit;">11</div> of these Notes to Condensed Consolidated Financial Statements (Unaudited) for information on revenue disaggregated by type and by geographic region.</div></div><span></span>

The Company uses historical data to estimate the expected life of the options.&nbsp; The risk-free interest rate for periods within the contractual life of an award is based on the US Treasury yield curve in effect at the time of grant. The estimated volatility is based on historical volatility and management's expectations of future volatility. The Company uses an estimated dividend payout of zero, as the Company has <div style="display: inline; font-style: italic; font: inherit;">not</div> paid dividends in the past and, at this time, does <div style="display: inline; font-style: italic; font: inherit;">not</div> expect to do so in the future.
