<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">Overview</p>

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Northern Technologies International Corporation (NTIC) develops and markets proprietary,
environmentally-beneficial products and services in over 60 countries either directly or via a network of subsidiaries, joint ventures,
independent distributors, and agents. NTIC&#8217;s primary business is corrosion prevention, marketed mainly under the ZERUST<sup>&#174;</sup>
brand. NTIC has been selling its proprietary ZERUST<sup>&#174;</sup> products and services to the automotive, electronics, electrical,
mechanical, military, and retail consumer markets for over 40 years and, in recent years, has targeted and expanded into the oil
and gas industry. NTIC also markets and sells a portfolio of bio-based and certified compostable (fully biodegradable) polymer
resin compounds and finished products under the Natur-Tec<sup>&#174;</sup> brand. These products are intended to reduce NTIC&#8217;s
customers&#8217; carbon footprint and provide environmentally sound waste disposal options.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products include plastic
and paper packaging, liquids, coatings, rust removers, cleaners, and diffusers as well as engineered solutions designed specifically
for the oil and gas industry. NTIC also offers worldwide, on-site, technical consulting for rust and corrosion prevention issues.
NTIC&#8217;s technical service consultants work directly with the end users of NTIC&#8217;s ZERUST<sup>&#174;</sup> rust and corrosion
inhibiting products to analyze their specific needs and develop systems to meet their performance requirements. In North America,
NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions through a network of independent distributors and agents supported
by a direct sales force.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Internationally, NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions
through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd. (NTIC China), its majority-owned joint venture holding
company for NTIC&#8217;s joint venture investments in the Association of Southeast Asian Nations (ASEAN) region, NTI Asean LLC
(NTI Asean), certain majority-owned and wholly-owned subsidiaries, and joint venture arrangements in North America, Europe, and
Asia. NTIC also sells products directly to its joint venture partners through its wholly-owned subsidiary in Germany, NTIC Europe
GmbH (NTI Europe).</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">One of NTIC&#8217;s strategic initiatives is to expand into and penetrate other markets
for its ZERUST<sup>&#174;</sup> corrosion prevention technologies. Consequently, for the past several years, NTIC has focused significant
sales and marketing efforts on the oil and gas industry, as the infrastructure that supports that industry is typically constructed
using metals that are highly susceptible to corrosion. NTIC believes that its ZERUST<sup>&#174;</sup> corrosion prevention solutions
will minimize maintenance downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure, and
reduce the risk of environmental pollution due to leaks caused by corrosion.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC markets and sells its ZERUST<sup>&#174;</sup> rust and corrosion prevention solutions
to customers in the oil and gas industry across several countries either directly, through its subsidiaries, or through its joint
venture partners and other strategic partners. The sale of ZERUST<sup>&#174;</sup> corrosion prevention solutions to customers in
the oil and gas industry typically involves long sales cycles, often including multi-year trial periods with each customer and
a slow integration process thereafter.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Natur-Tec<sup>&#174;</sup> bio-based and compostable plastics are manufactured using NTIC&#8217;s
patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec<sup>&#174;</sup>
biopolymer resin compound portfolio includes formulations that have been optimized for a variety of applications, including blown-film
extrusion, extrusion coating, injection molding, and engineered plastics. These resin compounds are certified to be fully biodegradable
in a composting environment and are currently being used to produce finished products, including can liners, shopping and grocery
bags, lawn and leaf bags, branded apparel packaging bags and accessories, and various foodservice items, such as disposable cutlery,
drinking straws, food-handling gloves, and coated paper products. In North America, NTIC markets its Natur-Tec<sup>&#174;</sup>
resin compounds and finished products primarily through a network of regional and national distributors as well as independent
agents. NTIC continues to see significant opportunities for finished bioplastic products and, therefore, continues to strengthen
and expand its North American distribution network for finished Natur-Tec<sup>&#174;</sup> bioplastic products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Internationally, NTIC sells its Natur-Tec<sup>&#174;</sup> resin compounds and finished
products both directly and through its wholly-owned subsidiary in China and majority-owned subsidiaries in India and Sri Lanka,
and through distributors and certain joint ventures.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Impact of COVID-19 Pandemic</b></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">In March 2020, the World Health Organization declared the novel coronavirus (COVID-19)
outbreak a global pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, created
significant volatility and disruption in financial markets and has resulted in an economic recession. As a result of the COVID-19
pandemic and related government mandated restrictions on the Company&#8217;s business, as well as the businesses of its joint ventures,
customers and suppliers, disruption to the Company&#8217;s business and the manufacture and sale of its products and services has
occurred and is expected to continue into fiscal 2021. Additionally, the Company expects the COVID-19 pandemic will likely continue
to have a material adverse effect on its business, operating results and financial condition in fiscal 2021; however, the precise

<p style="font-size: 10pt; margin: 0pt 0">NTIC receives funds from its joint ventures as fees received for services that NTIC provides
to its joint ventures and as dividend distributions. The fees for services provided to joint ventures are determined based on either
a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s joint venture in
Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for services. NTIC recognizes equity income from each joint venture
based on the overall profitability of the joint venture. Such profitability is subject to variability from quarter to quarter,
which, in turn, subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of each joint venture are shared
by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically directly or indirectly
owns 50% or less of each of its joint venture entities and, thus, does not control the decisions of these entities regarding whether
to pay dividends and, if paid, what amount is paid in a given year. The payment of a dividend by an entity is determined by a joint
vote of the owners and is not at the sole discretion of NTIC.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC derives revenues directly and/or indirectly through its subsidiaries and joint ventures
from two reportable business segments based on products sold, customer base, and distribution center: ZERUST<sup>&#174;</sup> corrosion
prevention solutions and Natur-Tec<sup>&#174;</sup> resin compounds and finished products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>ZERUST<sup>&#174;</sup> Corrosion Prevention Solutions</i></b>. In fiscal 2020,
72.4% of NTIC&#8217;s consolidated net sales were derived from developing, manufacturing and marketing ZERUST<sup>&#174;</sup> rust
and corrosion inhibiting products and services.&nbsp; NTIC&#8217;s consolidated net sales in fiscal 2020 included $34,474,535 in
sales of ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products and services, a decrease of 9.7% from such sales in fiscal
2019. Corrosion not only damages the appearance of metal products and components but also negatively impacts their mechanical performance.&nbsp;
This applies to the rusting of ferrous metals (iron and steel) and the deterioration by oxidation of nonferrous metals (aluminum,
copper, brass, etc.).&nbsp; NTIC&#8217;s ZERUST<sup>&#174;</sup> corrosion prevention solutions include plastic and paper packaging,
powders, liquids, coatings, rust removers, cleaners, diffusers, and engineered solutions for the oil and gas industry as well as
technical corrosion management and consulting services.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Plastic and Paper Packaging</i>.&nbsp; NTIC&#8217;s ZERUST<sup>&#174;</sup> packaging
products contain proprietary chemical formulations that continuously release an invisible and odorless corrosion inhibiting vapor
that passivates metal surfaces and thereby inhibits rust and corrosion.&nbsp; The corrosion inhibiting protection is maintained
as long as the metal products to be protected remain enclosed within the ZERUST<sup>&#174; </sup>packaging.&nbsp; Electron scanning
shows that once the contents are removed from the ZERUST<sup>&#174; </sup>packaging, the ZERUST<sup>&#174; </sup>protection dissipates
from the contents&#8217; surfaces within two hours, leaving a clean, dry, and corrosion-free metal component.&nbsp; This mechanism
of corrosion protection enables NTIC&#8217;s customers to easily package metal objects for rust-free shipment and/or long-term
storage.&nbsp; Furthermore, by eliminating costly greasing and degreasing processes and/or significantly reducing the use of certain
coatings to inhibit corrosion, NTIC&#8217;s ZERUST<sup>&#174; </sup>corrosion prevention solutions provide customers significant
savings in labor, material, and capital expenditures for equipment to apply, remove, and dispose of oils and greases, as well as
the attendant environmental problems, as compared to traditional methods of corrosion prevention.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC was first to develop the means of infusing volatile corrosion inhibiting chemical
systems (VCIs) into polyethylene and polypropylene resins.&nbsp; Combining ZERUST<sup>&#174; </sup>chemical systems with polyethylene
and polypropylene resins permitted NTIC to introduce a line of plastic packaging products in the form of low and high-density polyethylene
bags and shroud film, including stretch, shrink, skin, and bubble cushioning film, thereby giving packaging engineers an opportunity
to ship and store ferrous, nonferrous, and mixed-metal products in a clean, dry, and corrosion-free condition, with an attendant
overall savings in total process costs.&nbsp; In addition to plastic packaging, NTIC has developed additives to imbue kraft paper,
corrugated cardboard, solid fiber, and chipboard packaging materials with corrosion protection properties.&nbsp; NTIC&#8217;s ZERUST<sup>&#174;</sup>
plastic and paper packaging products come in various thicknesses, strength enhancements, protection types, shapes, and sizes. This
product line also includes items such as ZERUST<sup>&#174;</sup> gun cases, car covers, and tool-drawer liners, which are targeted
at retail consumers.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Liquids and Coatings</i>.&nbsp; NTIC&#8217;s corrosion prevention solutions include
a line of metal surface treatment liquids and coatings, which are oil, water, or bio-solvent based, and are marketed under brand
names including Axxatec<sup>&#8482;</sup>, Axxanol<sup>&#8482;</sup>, and Z-Maxx<sup>&#8482;</sup>.&nbsp; These liquids and coatings
provide powerful corrosion protection in aggressive environments, such as salt air, high humidity, and/or high temperatures.&nbsp;
Products are formulated for most metal types and protection levels. For exceptionally harsh environments, customers may choose
to use a combination of NTIC&#8217;s liquids and coatings with ZERUST<sup>&#174;</sup> plastic and/or paper products to achieve
robust corrosion protection during manufacturing, shipping, and warehousing stages.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Rust Removers and Cleaners</i>.&nbsp; NTIC also sells rust removal and cleaning products
designed to restore rusty parts to a usable condition without the use of labor-intensive, abrasive cleaners that damage surfaces
and commonly fail to remove rust from complex metal surfaces, like the teeth of small gears, under the Axxaclean<sup>&#8482;</sup>
brand name.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Diffusers</i>.&nbsp; NTIC&#8217;s corrosion prevention solutions include a line of
corrosion inhibiting vapor diffusers, such as ZERUST<sup>&#174;</sup> ActivPak<sup>&#174;</sup>, ZERUST<sup>&#174;</sup> ICT<sup>&#174;</sup>
Vapor Capsules, ZERUST<sup>&#174;</sup> ICT<sup>&#174;</sup> Plastabs<sup>&#174;</sup>, ZERUST<sup>&#174;</sup> ICT<sup>&#174;</sup>
Cor-Tabs<sup>&#174;</sup>, ZERUST<sup>&#174;</sup> ICT<sup>&#174;</sup> Pipe Strip, and ZERUST<sup>&#174;</sup> ICT<sup>&#174;</sup>
Tube Strip.&nbsp; These diffusers are designed to protect metals within enclosures, like switch gearboxes and electronic cabinets,
or can be used as added protection to ZERUST<sup>&#174;</sup> packaging products.&nbsp; Diffusers work by permeating the interior
air of an enclosure with an invisible and odorless corrosion inhibiting vapor that protects nearby metal surfaces that are within
a specific &#8220;radius of protection&#8221; for a period of one or two years depending on the model.&nbsp; This invisible and
dry protective layer revaporizes upon removal of the capsule from the enclosure, leaving all surfaces clean, dry, residue-free,
and corrosion-free.&nbsp;</p>

NTIC&#8217;s customers improve and control their corrosion management processes, NTIC markets and offers unique corrosion management
and consulting services to target customers.&nbsp; This ZERUST<sup>&#174;</sup> corrosion inhibition system (known as Z-CIS<sup>&#174;</sup>)
leverages NTIC&#8217;s global network to dispatch highly-trained technical service engineers to customer sites to solve complex

<p style="font-size: 10pt; margin: 0pt 0"><i>ZERUST<sup>&#174;</sup> Corrosion Prevention Solutions Designed Specifically for the
Oil and Gas Industry</i>.&nbsp; NTIC has developed proprietary engineered corrosion inhibiting solutions specifically for the mitigation
of corrosion of the types of capital assets used in the petroleum and chemical process industries and has targeted the sale of
these ZERUST<sup>&#174;</sup> corrosion solutions to potential customers in the oil and gas industry. NTIC&#8217;s consolidated
net sales in fiscal 2020 included $2,782,874 in sales made to customers in the oil and gas industry, an increase of 2.0% from such
sales in fiscal 2019. NTIC anticipates that its sales of ZERUST<sup>&#174;</sup> products and services into the oil and gas industry
will continue to remain subject to significant volatility, specifically due to the volatility of oil prices brought about by various
political factors, such as the recent price wars between Saudi Arabia and Russia, and economic factors, such as the recent price
drop and global production slowdown caused by travel and other restrictions related to the COVID-19 pandemic. Demand for ZERUST<sup>&#174;</sup>
oil and gas products around the world depends primarily on market acceptance and the reach of NTIC&#8217;s distribution network.
Because of the typical size of individual orders and overall size of NTIC&#8217;s net sales derived from sales of oil and gas products,
the timing of one or more orders can materially affect NTIC&#8217;s sales compared to prior fiscal year period sales. Projects
in Europe and the Middle East are a small but strategically important part of the sales growth picture. The infrastructure that
supports the oil and gas industry is predominantly constructed using metals that are highly susceptible to corrosion. The industrial
environment at these facilities usually contains compounds, including sulfides and chlorides, which cause aggressive corrosion.
This problem affects the service life and safety of pipelines, petroleum storage tanks, spare parts in long-term storage, processing,
and other critical equipment.&nbsp;In addition to the costs associated with the replacement of parts and structures, maintenance
and repairs, and product loss, there are significant economic losses associated with critical infrastructure being down for repair
and maintenance. Furthermore, there are also considerable health, safety, and environmental risks caused by corrosion that can
greatly increase economic losses.&nbsp; NTIC believes that its ZERUST<sup>&#174;</sup> oil and gas corrosion prevention solutions
minimize maintenance downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure, and reduce
the risk of environmental pollution due to leaks caused by corrosion.</p>

<p style="font-size: 10pt; margin: 0pt 0">ZERUST<sup>&#174;</sup> Flange Savers<sup>&#174;</sup> are specially designed covers that
have been impregnated with a proprietary ZERUST<sup>&#174;</sup> inhibitor formulation to provide corrosion protection for flanges,
valves, and welded joints.&nbsp; Oil and gas pipeline segments are connected by flanges and welded joints of varying sizes, designs,
and materials.&nbsp; These connection points often corrode under aggressive industrial environments and harsh operating conditions,
thereby causing costly maintenance, operational, and safety problems.&nbsp; ZERUST<sup>&#174;</sup> Flange Savers<sup>&#174;</sup>
are available in various sizes to accommodate different pipe diameters, pressure ratings, and international standards for pipeline
valves and flanges.&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">ZERUST<sup>&#174;</sup> ReCAST-SSB solutions protect the Soil Side Bottoms (SSB) of aboveground
storage tanks through a variety of unique and highly effective delivery systems designed by the Zerust Oil &amp; Gas team to deliver
proprietary Zerion FVS corrosion inhibitor to spaces under tank bottoms that are susceptible to significant corrosion. Tank bottoms
are typically made of steel plates, which are in direct contact with a foundation surface that may be concrete, sand/soil, or asphalt/bitumen.
It is typically not possible to protect this underside surface with traditional coatings. Cathodic protection (CP) systems can
only provide partial protection, but also have significant limitations that cause failures well ahead of the expected service life
of a tank. The ZERUST<sup>&#174;</sup> solutions provide effective protection even to areas that cannot be addressed with CP. These
are engineered solutions where each system is tailored to a customer&#8217;s requirements depending on factors including the tank
foundation design, specific environmental conditions, and tank diameter.</p>

and sells a broad range of bioplastic packaging solutions, including bio-based and certified compostable (fully biodegradable)
polymer resin compounds, and finished products under the Natur-Tec<sup>&#174;</sup> brand. NTIC&#8217;s consolidated net sales in
fiscal 2020 included $13,164,156 in sales of Natur-Tec<sup>&#174;</sup> resins and finished products, a decrease of 25.1% over such
sales in fiscal 2019.&nbsp; Market drivers such as volatile petroleum prices, reduced dependence on foreign oil, reduced carbon
footprints, requirements by multinational brands for sustainable packaging solutions that meet Circular Economy and environmentally
responsible end-of-life disposal mandates, and concerns about plastic residue in the environment have led to heightened interest
in using sustainable, bio-based and renewable plant-biomass resources for the manufacture of plastics and industrial products.
Plastics that are fully biodegradable in composting or anaerobic digestor systems allow the safe and effective conversion of these
plastics to carbon dioxide, water, and fertilizer at the end of their service life.&nbsp; Increased environmental and sustainability
awareness at the corporate and consumer level, improved technical properties and product functionality, as well as recent foreign,
state, and local governmental regulations banning the use of conventional plastics or mandating the use of certain biodegradable
or compostable products have also fueled this interest in bio-based and biodegradable-compostable plastics.&nbsp; The term &#8220;bio-plastics&#8221;
encompasses a broad category of plastics that are either bio-based, which means derived from renewable resources such as corn or
cellulosic/plant material or blends thereof, or are engineered to be fully compostable, or both.&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><B><I>ZERUST<SUP>&#174; </SUP>Corrosion Prevention Solutions</I></B>. While NTIC is
unaware of any third parties with which NTIC competes on a worldwide basis with respect to its corrosion prevention solutions,
NTIC does compete with several third parties on a regional basis. NTIC evaluates competing rust and corrosion inhibiting products
on an ongoing basis. Some of NTIC&#8217;s competitors are established companies that may have financial resources, marketing capabilities,
distribution networks and other resources substantially greater than those of NTIC. As a result, they may be able to adapt more
quickly to new or emerging technologies and changes in customer requirements or to devote greater resources to the promotion and
sale of their products than NTIC. With respect to its rust and corrosion inhibiting products, NTIC competes on the basis of product
innovation, quality, reliability, product support, customer service, reputation, and price. Some of NTIC&#8217;s competitors may
have achieved significant market acceptance of their competing products and brand recognition. NTIC, however, believes it has
an advantage over most of its competitors as a result of NTIC&#8217;s technical innovation and its value-added services. NTIC
attempts to provide its customers with the highest level of technical service and applications engineering in addition to ZERUST<SUP>&#174;
</SUP>rust and corrosion inhibiting products. Nonetheless, the commoditization of certain of NTIC&#8217;s ZERUST<SUP>&#174;</SUP>
rust and corrosion inhibiting products has led, and may continue to lead, to lower prices and lower margins on such products.
In addition, because certain barriers to entry are low, additional competitors may emerge, which likely would lead to the further
commoditization of NTIC&#8217;s rust and corrosion inhibiting products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">With respect to NTIC&#8217;s corrosion prevention solutions for use in the oil and gas
industry, NTIC&#8217;s primary barrier to entry is a combination of conservatism, complacency, and confidence in old approaches,
as well as the complexity of the buying organizations. Some of NTIC&#8217;s competitors with respect to its traditional ZERUST<SUP>&#174;
</SUP>rust and corrosion inhibiting products also compete in the oil and gas industry. NTIC also faces competition from new suppliers
who provide alternative approaches to corrosion prevention, some of which have a significant market presence and more years of
experience and credibility in the oil and gas industry. Original equipment manufacturer (OEM) suppliers to the oil and gas industry
present a new market vertical for NTIC&#8217;s traditional industrial ZERUST<SUP>&#174;</SUP> products.</p>

to NTIC&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds and finished products, NTIC competes with several established companies
that have been producing and selling similar products for a significantly longer time period and have significantly more sales,
more extensive and effective distribution networks, and better brand recognition than NTIC.&nbsp; Most of these companies also
have substantially more financial and other resources than NTIC.&nbsp; NTIC competes on the basis of performance, brand awareness,
distribution network, product availability, product offering, improved shelf life, place of manufacture, and price.&nbsp; Because
of price competition, NTIC&#8217;s margins on its Natur-Tec<sup>&#174;</sup> resin compounds and finished products are lower than
its margins on its ZERUST<sup>&#174;</sup> corrosion prevention solutions.&nbsp; NTIC also has encountered in the past and could
continue to encounter additional supply constraints for the base resins used to manufacture NTIC&#8217;s Natur-Tec<sup>&#174;</sup>

<p style="font-size: 10pt; margin: 0pt 0">The following are the most material factors known to NTIC that could materially adversely
affect its business, operating results, or financial condition.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Risks Related to NTIC&#8217;s Business and Industry</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Any weakness in the global economy, and in particular in the United States, Europe,
India and China, and in the automotive industry, may negatively impact NTIC&#8217;s business, operating results, and financial
condition. </i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">The U.S. and world economies may suffer from uncertainty, volatility, disruption, and
other adverse conditions, such as the impact of the COVID-19 pandemic, and those conditions have adversely impacted and may continue
to adversely impact the business community and the financial markets. Adverse economic and financial market conditions may negatively
affect NTIC&#8217;s customers and its markets, thereby negatively impacting its business and operating results. For example, weak
market conditions could extend the length of NTIC&#8217;s sales cycle and cause potential customers to delay, defer, or decline
to make purchases of NTIC&#8217;s products and services due to uncertainties surrounding the future performance of their businesses,
limitations on their capital expenditures due to internal budget constraints, the inability to obtain financing in the capital
markets, and the adverse effects of the economy on their business and financial condition. As a result, if economic and financial
market conditions weaken or deteriorate, then NTIC&#8217;s business, financial condition, and operating results, including its
ability to grow and expand its business and operations, could be materially and adversely affected.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt">NTIC&#8217;s operating results are especially dependent upon the economic health of the
economies in the United States, Europe, India and China. Since a significant portion of NTIC&#8217;s ZERUST<sup>&#174;</sup> rust
and corrosion inhibiting products and services are sold to customers in the automotive industry, adverse economic conditions affecting
the automotive industry, in particular, may result in an adverse effect on NTIC&#8217;s net sales and its other operating results.
Accordingly, any weakness in the global economy, particularly the United States, Europe, India and China, and in the automotive

<p style="font-size: 10pt; margin: 0pt 0"><b><i>The COVID-19 pandemic has adversely impacted and will likely continue to adversely
impact NTIC&#8217;s business, operating results and financial condition.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">The COVID-19 pandemic has resulted in a substantial curtailment of business activities
worldwide and has caused, and continues to cause, recessionary economic conditions in many countries, including the United States
and many countries abroad. As part of efforts to contain the spread of COVID-19, many state, local and foreign governments have
imposed various restrictions on the conduct of business and travel. While some of these restrictions have been curtailed or lifted,
others have been reinstated or may be reinstated in the future. Government restrictions, such as stay-at-home orders, quarantines
and worker absenteeism as a result of COVID-19 have led to a significant number of business closures and slowdowns. These business
closures and slowdowns adversely impacted, and will likely continue to adversely impact, NTIC directly and have caused its customers
and suppliers to slow or stop production, which has significantly disrupted and will likely continue to significantly disrupt NTIC&#8217;s
sales, production and supply chain. For example, as a result of the COVID-19 outbreak in China, NTIC experienced decreased demand
for its products and services in China and other places in Asia, commencing during the second quarter of fiscal 2020. These and
other factors contributed to NTIC experiencing significantly decreased global demand for its products and services during fiscal
2020, which will likely continue during fiscal 2021. This significantly decreased demand has had, and will likely continue to have,
a material adverse effect on NTIC&#8217;s business, operating results and financial condition in fiscal 2021. Due to the international
reach of COVID-19, NTIC anticipates that its international joint ventures will continue to be adversely impacted by the causes
listed above, as well as other local issues that may arise, which will likely continue to have a material adverse effect on NTIC&#8217;s
joint venture operations and equity in income from joint ventures. It is currently not possible to predict the precise potential
impact, as well as the extent of any impact, of the COVID-19 pandemic on NTIC&#8217;s business, and on the global economy as a
whole. It is also currently not possible to predict how long the pandemic will last or the time that it will take for economic
activity to return to prior levels. A prolonged situation could have a significant adverse effect on economies and financial markets
globally, potentially deepening the current worldwide economic downturn, which could have a significant adverse effect on NTIC&#8217;s
business, operating results and financial condition.</p>

<p style="font-size: 10pt; margin: 0pt 0">The extent to which the COVID-19 pandemic impacts NTIC&#8217;s business will likely depend
on numerous evolving factors that NTIC may not be able to accurately predict, including:</p>

condition. </i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">There is significant uncertainty about the future relationship between the United
States and other countries with respect to trade policies, taxes, government regulations, and tariffs. The current U.S.
administration has signaled support for implementing and, in some instances, has already proposed or taken action with
respect to major changes to certain trade policies in an effort to encourage U.S. production. Such changes include the
imposition of additional tariffs on imported products in an effort to address trade imbalances, specifically with China, the
withdrawal of the U.S. from the Trans-Pacific Partnership, and the renegotiation of the North American Free Trade Agreement.
In response to such actions, certain countries have imposed retaliatory actions against the U.S. NTIC and its subsidiaries
and joint ventures engage in sales outside of the United States and is, therefore, negatively impacted by such actions. Any
changes or potential changes in trade policies in the United States, including changes stemming from the 2020 presidential
election in the United States, and the potential corresponding actions by other countries in which NTIC does business could
adversely and materially affect NTIC&#8217;s business, results of operations, and financial condition.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Risks Related to NTIC&#8217;s Financial Position and Need for Additional Capital</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b>&nbsp;</b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Changes to the London Interbank Offered Rate (LIBOR) or the replacement of LIBOR
with an alternative reference rate may require NTIC to renegotiate its revolving line of credit.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">At the option of NTIC, outstanding advances under NTIC&#8217;s $3,000,000 revolving line
of credit with PNC Bank, National Association (PNC Bank) bear interest at either (a) an annual rate based on LIBOR plus 2.15% for
the applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its
prime rate. On July 27, 2017, the Financial Conduct Authority in the United Kingdom announced that it would phase out LIBOR as
a benchmark by the end of 2021. If LIBOR ceases to exist, NTIC may need to renegotiate its credit facility, and it may not be able
to do so on terms that are favorable to NTIC. Further, the overall financial market may be disrupted as a result of the phase-out
or replacement of LIBOR. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee
comprised of large U.S. financial institutions, is considering replacing LIBOR with the Secured Overnight Financing Rate (SOFR),
a new index calculated by short-term repurchase agreements, backed by Treasury securities. However, whether or not SOFR attains
market traction as a LIBOR replacement tool remains in question, and the future of LIBOR remains uncertain at this time. The uncertainty
related to the phase-out or replacement of LIBOR could disrupt the overall financial market and adversely affect NTIC&#8217;s ability
to renegotiate its revolving line of credit.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Global credit and financial markets in the past have experienced disruptions, including
diminished liquidity and credit availability and rapid fluctuations in market valuations, which, if they happen again, could negatively
impact NTIC&#8217;s business, operating results, and financial condition. </i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">Any tightening of the credit and financial markets could negatively impact the ability
of companies to borrow money from their existing lenders, obtain credit from other sources, or raise financing to fund their operations.
This could negatively impact the ability of NTIC&#8217;s customers and the customers of NTIC&#8217;s joint ventures to purchase
NTIC&#8217;s products, suppliers&#8217; ability to provide NTIC and its joint ventures with materials and components, and the ability
of NTIC and its joint ventures, distributors, and sales representatives to finance operations, if needed, on commercially reasonable
terms, or at all. Any or all of these events could negatively impact NTIC&#8217;s business, operating results, and financial condition.
Although NTIC maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers, distributors,
and joint ventures to make required payments, and such losses historically have been within NTIC&#8217;s expectations and the provisions
established, NTIC cannot guarantee that it will continue to experience the same loss rates that it has in the past, especially
if there are weaknesses in the worldwide economy. A significant change in the liquidity or financial condition of NTIC&#8217;s
customers, distributors, or joint ventures could cause unfavorable trends in NTIC&#8217;s receivable collections and additional
allowances may be required, which could adversely affect NTIC&#8217;s operating results. In addition, weaknesses in the worldwide
economy, including the imposition of higher tariffs and withdrawal from the Trans-Pacific Partnership, may adversely impact the
ability of suppliers to provide NTIC with materials and components, which could adversely affect NTIC&#8217;s business and operating
results. NTIC is unable to predict the prospects for a global economic recovery, but the longer the duration of such adverse and
uncertain economic conditions, the greater the risks NTIC faces in operating its business.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>NTIC&#8217;s liquidity and financial position rely on the receipt of fees for services
provided to its joint ventures and dividend distributions from its joint ventures. No assurance can be provided that NTIC will
continue to receive such fees and dividend distributions in amounts NTIC historically has received or anticipates receiving.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC conducts business, either directly or indirectly, through several joint venture
arrangements that operate in North America, Europe, and Asia. Each of these joint ventures manufactures, markets, and sells finished
products in the geographic territory that it is assigned. NTIC&#8217;s receipt of funds as a result of sales by its joint ventures
is dependent upon NTIC&#8217;s receipt of fees for services that NTIC provides to its joint ventures based primarily on the net
sales of the individual joint ventures and NTIC&#8217;s receipt of dividend distributions from its joint ventures based on the
profitability of its joint ventures. NTIC&#8217;s liquidity and financial position in part rely on NTIC&#8217;s receipt of fees
for services that NTIC provides to its joint ventures and dividend distributions from its joint ventures. During fiscal 2020, NTIC
recognized $4,612,885 in fees and $5,672,099 in dividend distributions from its joint ventures. Because NTIC owns 50% or less of
each of its joint venture entities, NTIC does not control the decisions of these entities regarding whether to pay dividends and,
if paid, how much they should be in any given year. Thus, NTIC cannot guarantee that any of its joint ventures will pay dividends
in any given year. The failure of NTIC&#8217;s joint ventures to declare dividends or the failure of NTIC to receive fees for services
provided to joint ventures in amounts typically expected by NTIC could adversely affect NTIC&#8217;s liquidity and financial position.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Since a significant portion of NTIC&#8217;s earnings results from NTIC&#8217;s
equity income from joint ventures, and since NTIC&#8217;s equity income from joint ventures varies from quarter to quarter, NTIC&#8217;s
earnings are subject to quarterly fluctuations.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">A significant portion of NTIC&#8217;s earnings results from NTIC&#8217;s equity income
from its joint ventures. NTIC&#8217;s equity in income from joint ventures consists of NTIC&#8217;s share of equity in income from
its joint ventures based on the overall profitability of the joint ventures. Such profitability varies from quarter to quarter.
Since NTIC&#8217;s management typically receives quarterly joint venture financial information after the completion of each fiscal
quarter, it is impossible for NTIC&#8217;s management to cut costs and expenses to make up for any unanticipated shortfall in NTIC&#8217;s
equity income from joint ventures. Accordingly, the variability in NTIC&#8217;s equity income from joint ventures, in turn, subjects
NTIC&#8217;s earnings to quarterly fluctuations.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC considers its joint venture in Germany (EXCOR) to be individually significant to
NTIC&#8217;s consolidated assets and income and, therefore, provides certain additional information regarding EXCOR in the notes

fiscal 2020. Of the total equity in income from joint ventures of $4,270,327 during fiscal 2020, NTIC had equity in income from
joint ventures of $2,622,423 attributable to EXCOR. Of the total fee income for services provided to joint ventures of $4,612,885
during fiscal 2020, fees of $843,752 were attributable to EXCOR. Accordingly, if sales of NTIC&#8217;s products and services by

such that the joint venture terminated or was not motivated to sell NTIC&#8217;s products and services, NTIC&#8217;s operating

<p style="font-size: 10pt; margin: 0pt 0">The sale and shipping of products and services across international borders subjects
NTIC to extensive and complicated U.S. and foreign governmental trade regulations. Compliance with such regulations is costly and
exposes NTIC to penalties for non-compliance. Other laws and regulations that can significantly impact NTIC include various anti-bribery
laws, including the U.S. Foreign Corrupt Practices Act, laws restricting business with suspected terrorists, and anti-boycott laws.
Any failure to comply with applicable legal and regulatory obligations could impact NTIC in a variety of ways that include, but
are not limited to, significant criminal, civil, and administrative penalties, including imprisonment of individuals, fines and
penalties, denial of export privileges, seizure of shipments, and restrictions on certain business activities. Also, the failure
to comply with applicable legal and regulatory obligations could result in the disruption of NTIC&#8217;s shipping and sales activities.</p>

which voters approved an exit from the European Union, commonly referred to as &#8220;Brexit.&#8221; The United Kingdom officially
terminated its membership of the European Union on January 31, 2020 and will remain in a transition phase until December 31, 2020.
The British government continues to negotiate the terms of the United Kingdom&#8217;s future relationship with the European Union.
Although it is unknown what those terms will be, or whether an agreement will be reached, it is possible that there will be increased
regulatory complexities, which could affect NTIC&#8217;s ability to sell its products in certain European Union countries.&nbsp;Brexit&nbsp;has
created legal, political and economic uncertainty, which could subject NTIC to heightened risks in that region, including disruptions
to trade and free movement of goods, services, and people to and from the United Kingdom, and increased foreign exchange volatility
with respect to the British pound. NTIC does not know to what extent these changes will impact its business. Any of these effects
of Brexit, and other similar referenda that NTIC cannot anticipate, could adversely affect its business, operations, and financial
results.</p>

its ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products for the oil and gas industry and its Natur-Tec<sup>&#174;</sup>

There is no assurance that NTIC has the necessary operational and financial resources to manage its growth. This is especially
true as it expands facilities and manufactures its products on a larger commercial scale. In addition, rapid growth in NTIC&#8217;s
headcount and operations may place a significant strain on its management, administrative, operational, and financial infrastructure.
Failure to adequately manage its growth could have a material and adverse effect on NTIC&#8217;s business, operating results, and
financial condition. For example, NTIC&#8217;s soil side bottom solutions for tanks require implementation teams comprised of both
internal NTIC personnel and outside consulting firms. NTIC&#8217;s failure to expand these implementation teams to service additional
customers may limit NTIC&#8217;s ability to grow this business. In addition, NTIC may not be successful in its strategy to grow
its business.</p>

<p style="font-size: 10pt; margin: 0pt 0">Chinese commercial law is relatively undeveloped compared to commercial law in many of
NTIC&#8217;s other major markets, and limited protection of intellectual property is available in China as a practical matter.
Although NTIC takes precautions in the operation of NTIC China to protect NTIC&#8217;s intellectual property, any local manufacturer
of products that NTIC undertakes in China could subject NTIC to an increased risk that unauthorized parties will be able to copy
or otherwise obtain or use NTIC&#8217;s intellectual property, which could harm NTIC&#8217;s business. NTIC may also have limited

operations of NTIC China.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC China is subject to laws and regulations applicable to foreign investment in China.
There are uncertainties regarding the interpretation and enforcement of laws, rules, and policies in China. The Chinese legal system
is based on written statutes, and prior court decisions have limited precedential value. Because many laws and regulations are
relatively new, and the Chinese legal system is still evolving, the interpretations of many laws, regulations, and rules are not
always uniform. Moreover, the relative inexperience of China&#8217;s judiciary in many cases creates additional uncertainty as
to the outcome of any litigation, and the interpretation of statutes and regulations may be subject to government policies reflecting
domestic political agendas. Finally, enforcement of existing laws or contracts based on existing law may be uncertain and sporadic.
For the preceding reasons, it may be difficult for NTIC or NTIC China to obtain timely or equitable enforcement of laws ostensibly
designed to protect companies like NTIC or NTIC China, which could adversely affect NTIC&#8217;s business, results of operations,
and financial condition.</p>

effect on its business, results of operations, and financial condition.</i></b></p>

<p style="font-size: 10pt; text-indent: 0in; margin: 0pt 0">NTIC is subject to the U.S. Foreign Corrupt Practices Act, or the FCPA,
which generally prohibits covered entities and their intermediaries from engaging in bribery or making other prohibited payments
to foreign officials for the purpose of obtaining or retaining business or other benefits. In addition, the FCPA imposes accounting
standards and requirements on U.S. publicly-traded corporations and their foreign affiliates, which are intended to prevent the
diversion of corporate funds to the payment of bribes and other improper payments and to prevent the establishment of &#8220;off
books&#8221; slush funds from which such improper payments can be made. NTIC also is subject to similar anticorruption legislation
implemented in Europe under the Organization for Economic Co-operation and Development&#8217;s Convention on Combating Bribery
of Foreign Public Officials in International Business Transactions. NTIC and its joint ventures, distributors, independent representatives,
and agents operate in a number of jurisdictions that pose a high risk of potential violations of the FCPA and other anticorruption
laws, based on measurements such as Transparency International&#8217;s Corruption Perception Index, and NTIC utilizes a number
of joint ventures, distributors, independent representatives, and agents for whose actions NTIC could be held liable under the
FCPA. NTIC informs its personnel, joint ventures, distributors, independent representatives, and agents of the requirements of
the FCPA and other anticorruption laws, including, but not limited to, their reporting requirements. NTIC also has developed and
will continue to develop and implement systems for formalizing its contracting processes, performing due diligence on agents, and
improving its recordkeeping and auditing practices regarding these regulations. However, there is no guarantee that NTIC&#8217;s
employees, joint ventures, distributors, independent representatives, or other agents have not or will not engage in conduct undetected
by NTIC&#8217;s processes and for which NTIC might be held responsible under the FCPA or other anticorruption laws.</p>

<p style="font-size: 10pt; text-indent: 0in; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">If NTIC&#8217;s employees, joint ventures, distributors, third-party sales representatives,

disgorgement, and other remedial measures, including further changes or enhancements to its procedures, policies, and controls
and potential personnel changes and disciplinary actions.</p>

<p style="font-size: 10pt; margin: 0pt 0">Certain private and foreign companies, including some of NTIC&#8217;s competitors, are
not subject to prohibitions as strict as those under the FCPA or, even if subjected to strict prohibitions, such prohibitions may
be laxly enforced in practice. If NTIC&#8217;s competitors engage in corruption, extortion, bribery, pay-offs, theft, or other
fraudulent practices, they may receive preferential treatment from personnel of some companies or from government officials, giving
NTIC&#8217;s competitors an advantage in securing business and putting NTIC at a disadvantage.</p>

Korean Won, and the English Pound against the U.S. dollar. NTIC&#8217;s fees for services provided to its joint ventures and dividend
distributions from these foreign entities are paid in foreign currencies; thus, fluctuations in foreign currency exchange rates
could result in declines in NTIC&#8217;s earnings. Any changes in foreign currency exchange rates would be reflected as a foreign

NTIC&#8217;s operations and earnings. Such risks include the financial instability among customers in these regions, political
instability, fraud or corruption, and other non-economic factors, such as the impact of the COVID-19 pandemic and irregular trade
flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing
countries can be vague, inconsistently administered, and retroactively applied. If NTIC is deemed not to be in compliance with
applicable laws in developing countries where NTIC conducts business, its prospects and business in those countries could be harmed,

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s products are sold in intensely competitive markets throughout the world.
This intense competition could result in pricing pressures, lower sales, reduced margins, and lower market share. With respect
to its rust and corrosion inhibiting products, NTIC competes on the basis of product innovation, quality, reliability, product
support, customer service, reputation, and price. With respect to its Natur-Tec<sup>&#174;</sup> resin compounds and finished products,
NTIC competes on the basis of performance, brand awareness, distribution network, product availability, product offering, shelf
life, place of manufacture, and price. NTIC often competes with numerous manufacturers, many of which have substantially greater
financial, marketing, and other resources than NTIC. As a result, they may be able to adapt more quickly than NTIC to new or emerging
technologies, industry trends, and changes in customer requirements or to devote greater resources to the promotion and sale of
their products than NTIC. In addition, competition could increase if new companies enter the markets in which NTIC competes, especially
when the barriers to entry are low, which may be true with respect to NTIC&#8217;s rust and corrosion prevention business, or if
existing competitors expand their product lines or intensify efforts within existing product lines. NTIC&#8217;s current products,
products under development, and its ability to develop new and improved products may be insufficient to enable NTIC to compete
effectively with its competitors. No assurance can be provided that NTIC will be able to compete effectively, which would harm
its business and operating results. In particular, NTIC has experienced more intense competition with respect to many of its traditional
ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products and services, which has led to decreased pricing and smaller margins
for NTIC. Recently, NTIC has experienced lower margins on its contracts with Chinese automotive customers. NTIC anticipates that
such intense competition likely will continue and that new competitors may emerge, including plastic extrusion companies, which
would continue to adversely affect NTIC&#8217;s operating results.</p>

its customers&#8217; orders.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC utilizes contract manufacturers for a significant portion of its production requirements.
The majority of NTIC&#8217;s manufacturing is conducted in the United States by contract manufacturers that also perform services
for numerous other companies. NTIC does not have a guaranteed level of production capacity with any of its contract manufacturers.
Qualifying new contract manufacturers is time consuming and might result in unforeseen manufacturing and operations problems. The
loss of NTIC&#8217;s relationships with its contract manufacturers or their inability to conduct their manufacturing and assembly
services for NTIC as anticipated in terms of capacity, cost, quality, and timeliness could adversely affect NTIC&#8217;s ability
to fill customer orders in accordance with required delivery, quality, and performance requirements, thus adversely affecting NTIC&#8217;s
net sales and other operating results.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>NTIC&#8217;s dependence on manufacturing and logistical services provided by contractors
could give rise to product defect or warranty liability.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC uses third party manufacturers to produce the majority of its products. In addition,
NTIC relies upon certain contractors for logistical services. Although NTIC&#8217;s arrangements with its contract manufacturers
and contractors may contain provisions for warranty expense reimbursement, NTIC may remain responsible to its customers for warranty
service in the event of product defects and could experience an unanticipated&nbsp;product defect&nbsp;or warranty liability. In
addition, product defects could harm NTIC&#8217;s reputation amongst its customers.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>&nbsp;</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>NTIC&#8217;s dependence on key suppliers puts NTIC at risk of interruptions in
the availability of its products, which could reduce its net sales and adversely affect its operating results and harm its reputation.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC relies on suppliers for certain raw materials and components used in its products.
For reasons of quality assurance, cost effectiveness, or availability, NTIC procures certain raw materials and components from
sole or limited source suppliers. Among the limited source suppliers NTIC does business with are the manufacturers of plastic resins
used in Natur-Tec<sup>&#174;</sup> products. NTIC generally acquires these and other raw materials and components through purchase
orders placed in the ordinary course of business, and as a result, NTIC does not have a significant inventory of these materials
and components and does not have any guaranteed or contractual supply arrangements with many of these suppliers for these materials
and components. NTIC&#8217;s dependence on third-party suppliers involves several risks, including limited control over pricing,
availability, quality, and delivery schedules, as well as manufacturing yields and costs. Suppliers of such raw materials and components
may decide, or be required, for reasons beyond NTIC&#8217;s control, to cease supplying such raw materials and components to NTIC
or to raise their prices.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Shortages of raw materials, quality control problems, production capacity constraints,
or delays by suppliers could negatively affect NTIC&#8217;s ability to meet its production obligations and result in increased
prices for affected parts. For example, the rapid growth in demand for bioplastics products globally has increased the demand and
the price for plastic resins, and limited suppliers of such plastic resins may experience shortages caused by demand outpacing
their production capabilities, which could result in NTIC&#8217;s inability to produce its Natur-Tec<sup>&#174;</sup> products promptly
or in the volumes demanded. These and other shortages, constraints, or delays may result in delays in shipments of products or
components, which could adversely affect NTIC&#8217;s net sales and other operating results and its reputation. From time to time,
materials and components used in NTIC&#8217;s products are subject to allocation because of shortages of these materials and components.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC uses certain raw materials and components in its products, including in particular
plastic resins, which are subject to price increases. In light of increased global demand for bioplastics, the prices of certain

</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">Although there is a developed market for petroleum-based plastics, the market for &#8220;bioplastics&#8221;
which are plastics produced with bio-based resins, which are derived from renewable resources such as corn or cellulosic/plant
material or blends thereof, or plastics that are engineered to be fully biodegradable or both, is still developing. The commercial
success of NTIC&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds and finished products depends on the widespread market acceptance
of products manufactured with bio-based and biodegradable resins. It is currently difficult to assess or predict with any assurance
the potential size, timing, and viability of market opportunities for NTIC&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds and
finished products. The traditional plastics market sector is well-established with entrenched competitors with whom NTIC competes.
Pricing for traditional plastics has been highly volatile in recent years, which drives, to some extent, the commercial and other
support for bioplastics. While NTIC expects to be able to command a premium price for its Natur-Tec<sup>&#174;</sup> resin compounds
and finished products, a widening gap in the pricing for bioplastics versus petroleum-based plastics may reduce the size of the
addressable market for NTIC&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds and finished products. In addition, the growth of
the market will create some pressure on price for applications today considered commodities, including in particular NTIC&#8217;s
current Natur-Tec<sup>&#174;</sup> finished products.</p>

plans. NTIC&#8217;s failure to maintain its existing relationships with these entities, or its failure to recruit and retain additional
skilled joint venture partners, distributors, manufacturer&#8217;s sales representatives, and other agents, could have an adverse
effect on NTIC&#8217;s operations. It is anticipated that several of NTIC&#8217;s joint venture partners will retire during the

corrosion inhibiting products into the oil and gas industry, particularly in the United States, has been and may continue to be
hampered by low global crude oil prices. Low global crude oil prices have recently been caused by oversupply, price wars between
Saudi Arabia and Russia and the impact of the COVID-19 pandemic. NTIC believes low global crude oil prices constrain capital improvement
budgets of its existing and prospective customers and may result in personnel turnover at its oil and gas customers or prospects.</p>

and its operating results.</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s business, properties, and products are subject to a wide variety of international,
federal, state, and local laws, rules, taxes, and regulations relating to the protection of the environment, natural resources,
and worker health and safety and the use, management, storage, and disposal of hazardous substances, wastes, and other regulated
materials. These laws, rules, and regulations may affect the way NTIC conducts its operations, and the failure to comply with these
regulations could lead to fines and other penalties. Because NTIC owns and operates real property, various environmental laws also
may impose liability on NTIC for the costs of cleaning up and responding to hazardous substances that may have been released on
NTIC&#8217;s property, including releases unknown to NTIC. These environmental laws and regulations also could require NTIC to
pay for environmental remediation and response costs at third-party locations where NTIC disposed of or recycled hazardous substances.
NTIC&#8217;s future costs of complying with the various environmental requirements, as they now exist or may be altered in the
future, could adversely affect NTIC&#8217;s financial condition and operating results. NTIC is also subject to other international,
federal, and state laws, rules, and regulations, the future non-compliance with which may harm NTIC&#8217;s business or may adversely
affect the demand for some of its products. Changes in laws and regulations, including changes in accounting standards and taxation
changes, including tax rate changes, new tax laws, and revised tax law interpretations, also may adversely affect NTIC&#8217;s

<p style="font-size: 10pt; margin: 0pt 0">The mix of pre-tax income or loss among the tax jurisdictions in which NTIC operates,
which have varying tax rates, could impact NTIC&#8217;s effective tax rate. NTIC is subject to income taxes as well as non-income
based taxes in both the United States and various foreign jurisdictions. Judgment is required in determining the worldwide provision
for income taxes, other tax liabilities, interest, and penalties. Future events could change management&#8217;s assessment. NTIC
operates within multiple taxing jurisdictions and is subject to tax audits in these jurisdictions. These audits can involve complex
issues, which may require an extended period of time to resolve. NTIC also has made assumptions about the realization of deferred
tax assets. Changes in these assumptions or jurisdictional regulations could result in a valuation allowance for these assets.
Final determination of tax audits or tax disputes may be different from what is currently reflected by NTIC&#8217;s income tax
provisions and accruals. During fiscal year 2020, NTIC recorded income tax expense of approximately $1,600,000 related to the determination
that it was more likely than not that all or some of NTIC&#8217;s deferred tax assets would not be realized.</p>

with FDA regulations if the components used in the food and beverage containers: (i) are approved by the FDA as indirect food additives
for their intended uses and comply with the applicable FDA indirect food additive regulations; or (ii) are generally recognized
as safe for their intended uses and are of suitable purity for those intended uses. NTIC believes that its Natur-Tec<sup>&#174;</sup>

President and Chief Executive Officer and director, as well as two other members of the Lynch family. Mr. Lynch shares voting and
dispositive power of shares of NTIC&#8217;s common stock held by Inter Alia with the other owners. As a result of his share ownership
through Inter Alia and his position as President and Chief Executive Officer and director of NTIC, Mr. Lynch may be able to influence
the affairs and actions of NTIC, including matters requiring stockholder approval, such as the election of directors and approval
of significant corporate transactions. The interests of Mr. Lynch and Inter Alia may differ from the interests of NTIC&#8217;s
other stockholders. This concentration of ownership may have the effect of delaying, preventing, or deterring a change in control
of NTIC, could deprive NTIC&#8217;s stockholders of an opportunity to receive a premium for their common stock as part of a sale

by this concentration of ownership include proxy contests, tender offers, mergers, or other purchases of common stock that could

a negative impact on the performance of the company. In addition, none of NTIC&#8217;s employees have any contractual obligation
to maintain his or her employment with NTIC. The loss or interruption of services of any of NTIC&#8217;s key personnel, including
in particular its technical personnel, the inability to identify, attract, or retain qualified personnel in the future, delays
in hiring qualified personnel, or any employee slowdowns, strikes, or similar actions could make it difficult for NTIC to manage

<p style="font-size: 10pt; margin: 0pt 0">The efficient operation of NTIC&#8217;s business is dependent on its management information
systems. NTIC relies on its management information systems to effectively manage accounting and financial functions; manage order

information systems are vulnerable to damage or interruption from natural or man-made disasters, including terrorist attacks, attacks

systems to store and access proprietary business information. NTIC faces various&nbsp;cyber security threats, including&nbsp;cyber
security&nbsp;attacks to its information technology infrastructure and attempts by others to gain access to its proprietary or
sensitive information. The procedures and controls NTIC uses to monitor these threats and mitigate its exposure may not be sufficient
to prevent&nbsp;cyber security&nbsp;incidents. The result of these incidents could include disrupted operations, lost opportunities,
misstated financial data, liability for stolen assets or information, increased costs arising from the implementation of additional
security protective measures, litigation, and reputational damage. Any remedial costs or other liabilities related to&nbsp;cyber

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s quarterly operating results vary from quarter to quarter for a variety of
reasons. For example, NTIC&#8217;s quarterly sales to joint ventures can be affected by individual orders to joint ventures. Because
of the typical size of individual orders to joint ventures and the overall size of NTIC&#8217;s net sales to joint ventures, the
timing of one or more orders can materially affect NTIC&#8217;s quarterly sales to joint ventures and the comparisons to prior
year quarters. In addition, because of the typical size of individual orders and the overall size of NTIC&#8217;s net sales derived
from sales of Natur-Tec<sup>&#174;</sup> products, the timing of one or more orders can materially affect NTIC&#8217;s quarterly
sales of Natur-Tec<sup>&#174;</sup> products and the comparisons to prior year quarters. Furthermore, since ZERUST<sup>&#174;</sup>
products for the oil and gas industry typically carry higher margins than other traditional ZERUST<sup>&#174;</sup> products, the
amount of sales of ZERUST<sup>&#174;</sup> products for the oil and gas industry typically affects NTIC&#8217;s overall margins.
Such variability in operating results makes the prediction of NTIC&#8217;s net sales, earnings, and other operating results for
each quarter difficult and increases the risk of unanticipated variations in quarterly operating results. NTIC&#8217;s quarterly
results have been and, in the future, may be below the expectations of public market analysts and investors.</p>

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC develops and markets proprietary, environmentally beneficial products and services
in over 60 countries either directly or via a network of subsidiaries, joint ventures, independent distributors, and agents. NTIC&#8217;s
primary business is corrosion prevention, marketed mainly under the ZERUST<sup>&#174;</sup> brand. NTIC has been selling its proprietary
ZERUST<sup>&#174;</sup> products and services to the automotive, electronics, electrical, mechanical, military, and retail consumer
markets for over 40 years and, in recent years, has targeted and expanded into the oil and gas industry. NTIC also markets and
sells a portfolio of bio-based and certified compostable (fully biodegradable) polymer resin compounds and finished products under
the Natur-Tec<sup>&#174;</sup> brand. These products are intended to reduce NTIC&#8217;s customers&#8217; carbon footprint and provide
environmentally sound waste disposal options.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products include plastic
and paper packaging, liquids, coatings, rust removers, cleaners, and diffusers as well as engineered solutions designed specifically
for the oil and gas industry. NTIC also offers worldwide, on-site, technical consulting for rust and corrosion prevention issues.
NTIC&#8217;s technical service consultants work directly with the end users of NTIC&#8217;s ZERUST<sup>&#174;</sup> rust and corrosion
inhibiting products to analyze their specific needs to meet their performance requirements. In North America, NTIC sells its ZERUST<sup>&#174;</sup>
corrosion prevention solutions through a network of independent distributors and agents supported by a direct sales force.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Internationally, NTIC sells its ZERUST<sup>&#174;</sup> corrosion prevention solutions
through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd. (NTIC China), its majority-owned joint venture holding
company for NTIC&#8217;s joint venture investments in the Association of Southeast Asian Nations (ASEAN) region, NTI Asean LLC
(NTI Asean), certain majority-owned and wholly-owned subsidiaries, and joint venture arrangements in North America, Europe, and
Asia. NTIC also sells products directly to its joint venture partners through its wholly-owned subsidiary in Germany, NTIC Europe
GmbH (NTI Europe).</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">One of NTIC&#8217;s strategic initiatives is to expand into and penetrate other markets
for its ZERUST<sup>&#174;</sup> corrosion prevention technologies. Consequently, for the past several years, NTIC has focused significant
sales and marketing efforts on the oil and gas industry, as the infrastructure that supports that industry is typically constructed
using metals that are highly susceptible to corrosion. NTIC believes that its ZERUST<sup>&#174;</sup> corrosion prevention solutions
will minimize maintenance downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure, and
reduce the risk of environmental pollution due to corrosion leaks.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC markets and sells its ZERUST<sup>&#174;</sup> rust and corrosion prevention solutions
to customers in the oil and gas industry across several countries either directly, through its subsidiaries, or through its joint
venture partners and other strategic partners. The sale of ZERUST<sup>&#174;</sup> corrosion prevention solutions to customers in
the oil and gas industry typically involves long sales cycles, often including multi-year trial periods with each customer and
a slow integration process thereafter.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Natur-Tec<sup>&#174;</sup> bio-based and compostable plastics are manufactured using NTIC&#8217;s
patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec<sup>&#174;</sup>
biopolymer resin compound portfolio includes formulations that have been optimized for a variety of applications, including blown-film
extrusion, extrusion coating, injection molding, and engineered plastics. These resin compounds are certified to be fully biodegradable
in a composting environment and are currently being used to produce finished products, including can liners, shopping and grocery
bags, lawn and leaf bags, branded apparel packaging bags and accessories, and various foodservice items, such as disposable cutlery,
drinking straws, food-handling gloves, and coated paper products. In North America, NTIC markets its Natur-Tec<sup>&#174;</sup>
resin compounds and finished products primarily through a network of regional and national distributors as well as independent
agents. NTIC continues to see significant opportunities for finished bioplastic products and, therefore, continues to strengthen
and expand its North American distribution network for finished Natur-Tec<sup>&#174;</sup> bioplastic products.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC participates in 19 active joint venture arrangements in North America, Europe, and
Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned.
While most of NTIC&#8217;s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also
sell NTIC&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds. NTIC has historically funded its investments in joint ventures with
cash generated from operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s receives funds from its joint ventures as fees for services that NTIC provides
to its joint ventures and as dividend distributions. The fees for services provided to joint ventures are determined based on either
a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s joint venture in
Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for services. NTIC recognizes equity income from each joint venture
based on the overall profitability of the joint venture. Such profitability is subject to variability from quarter to quarter,
which, in turn, subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of each joint venture are shared
by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically directly or indirectly
owns 50% or less of each of its joint venture entities and, thus, does not control the decisions of these entities regarding whether
to pay dividends and, if paid, what amount is paid in a given year. The payment of a dividend by an entity is determined by a joint
vote of the owners and is not at the sole discretion of NTIC.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b>Impact of the COVID-19 Pandemic</b></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">In March 2020, the World Health Organization declared the novel coronavirus (COVID-19)
outbreak a global pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, created
significant volatility and disruption in financial markets and has resulted in an economic recession. The outbreak and continuing
rapid spread of COVID-19 has resulted in a substantial curtailment of business activities worldwide and is causing weakened economic
conditions, both in the United States and abroad.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As part of efforts to contain the spread of COVID-19, federal, state, local and foreign
governments imposed various restrictions on the conduct of business and travel, some of which remain in place in whole or in part.
Government restrictions, such as stay-at-home orders, quarantines and worker absenteeism as a result of COVID-19, have led to a
significant number of business closures and slowdowns. These business closures and slowdowns have adversely impacted and will likely
continue to adversely impact NTIC directly and have caused some of NTIC&#8217;s customers and suppliers to operate at a fraction
of their capacities or wholly lock down, which has disrupted and may continue to disrupt NTIC&#8217;s sales and production.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As the events surrounding the COVID-19 pandemic unfolded, NTIC&#8217;s primary focus
was, and continues to be, the health, safety and wellbeing of its employees, customers and suppliers. In order to continue its
operations, as permitted by respective state, local and foreign governments, NTIC has adopted numerous safety measures in accordance
with U.S. Centers for Disease Control and Prevention, World Health Organization, and federal, state, local and foreign guidance
in order to protect its employees, customers and suppliers. These safety measures include, but are not limited to, adhering to
social distancing protocols, enabling the majority of its employees to work from home, suspending non-essential travel, disinfecting
facilities and workspaces extensively and frequently, suspending all non-essential visitors and requiring employees who must be
present at NTIC&#8217;s facilities to wear face coverings. NTIC expects to continue such safety measures for the foreseeable future
and may take further actions, or adapt these existing policies, as government authorities may require or recommend or as it may
determine to be in the best interests of its employees, customers and suppliers.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC has been balancing its safety-focused approach with the needs of its customers.
Government mandated measures resulting in the substantial curtailment of business activities generally have excluded certain essential
businesses and services, including certain manufacturing. With the exception of the temporary closures of NTIC&#8217;s facilities
in China and India during the second and third fiscal quarters of 2020, NTIC&#8217;s manufacturing activities are generally considered
part of the &#8220;critical sector&#8221; with respect to state and local government orders. This has allowed NTIC to continue
to receive orders and provide uninterrupted order fulfillment to its customers. However, its facilities have been operating at
a reduced capacity in order to abide by local government requirements and recommendations, such as social distancing practices,
and in response to reduced demand. At various times during the second, third, and fourth quarters of fiscal 2020, certain of NTIC&#8217;s
facilities were impacted by reduced levels of production, manufacturing inefficiencies due to the reconfiguration of certain of
its manufacturing processes in order to implement social distancing protocols and reduced demand. NTIC has engaged and continues
to engage in communications with its suppliers in an attempt to identify and mitigate supply chain risks and proactively manage
inventory levels in order to align production with demand. While domestic and international governmental measures may be modified
or extended, NTIC currently expects that its global facilities will remain operational, although operating at reduced production
capacity at certain of its facilities. However, such expectation is dependent upon future governmental actions and demand for NTIC&#8217;s
products, the stability of its global supply chain and the ability of carriers to transport supplies to its facilities and products
to its customers.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As a result of the global economic slowdown caused by the COVID-19 pandemic, NTIC experienced
significantly decreased demand for its products, beginning with its second quarter of fiscal 2020, compared to the prior fiscal
year periods, which had a material adverse effect on NTIC&#8217;s operating results. NTIC anticipates continued softened global
demand for its products and services during fiscal 2021. Due to the international reach of COVID-19, NTIC&#8217;s international
joint ventures have also been adversely impacted, which has had and may continue to have a material adverse effect on NTIC&#8217;s
joint venture operations and equity in income from joint ventures. It is currently not possible to predict the precise potential
impact, as well as the extent of any future impact, of the COVID-19 pandemic on NTIC&#8217;s business and on the global economy
as a whole. It is also currently not possible to predict how long the pandemic will last or the time that it will take for economic
activity to return to prior levels. A prolonged situation could have a significant adverse effect on economies and financial markets
globally, potentially leading to a significant worldwide economic downturn, which could have a significant adverse effect on NTIC&#8217;s
business, operating results and financial condition.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s management, including its chief executive officer, who is NTIC&#8217;s chief
operating decision maker, reports and manages NTIC&#8217;s operations in two reportable business segments based on products sold,
customer base, and distribution center: ZERUST<sup>&#174;</sup> products and services and Natur-Tec<sup>&#174;</sup> products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s consolidated net sales decreased 14.5% during fiscal 2020 compared to fiscal
2019. NTIC&#8217;s consolidated net sales for fiscal 2020 were adversely affected by reduced demand globally as a result of the
COVID-19 pandemic. NTIC anticipates that the COVID-19 pandemic will continue to significantly adversely affect NTIC&#8217;s consolidated
net sales and earnings during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During fiscal 2020, 72.4% of NTIC&#8217;s consolidated net sales were derived from sales
of ZERUST<sup>&#174;</sup> products and services, which decreased 9.7% to $34,474,535 during fiscal 2020 compared to $38,174,712
during fiscal 2019. This decrease was due to lower sales to existing customers for products as a result of decreased demand, primarily
as a result of the COVID-19 pandemic. NTIC has focused its sales efforts of ZERUST<sup>&#174;</sup> products and services by strategically
targeting customers with specific corrosion issues in new market areas, including the oil and gas industry and other industrial
sectors that offer sizable growth opportunities. NTIC&#8217;s consolidated net sales for fiscal 2020 included $2,782,874 of sales
made to customers in the oil and gas industry compared to $2,727,283 for fiscal 2019. Overall demand for ZERUST<sup>&#174;</sup>
products and services depends heavily on the overall health of the markets in which NTIC sells its products, including the automotive,
oil and gas, agriculture, and mining markets in particular. NTIC&#8217;s sales of ZERUST<sup>&#174;</sup> products and services
for fiscal 2020 were adversely affected by reduced demand globally as a result of the COVID-19 pandemic. NTIC anticipates that
the COVID-19 pandemic will continue to significantly adversely affect sales of ZERUST<sup>&#174;</sup> products and services during
fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During fiscal 2020, 27.6% of NTIC&#8217;s consolidated net sales were derived from sales
of Natur-Tec<sup>&#174;</sup> products compared to 31.5% during fiscal 2019. Net sales of Natur-Tec<sup>&#174;</sup> products decreased
25.1% to $13,164,156 during fiscal 2020 compared to fiscal 2019 primarily due to a decrease in finished product sales in North
America and finished product sales at NTIC&#8217;s majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec
India) and reduced demand globally as a result of the COVID-19 pandemic. NTIC anticipates that the COVID-19 pandemic will continue
to significantly adversely affect sales of Natur-Tec<sup>&#174;</sup> products during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Cost of goods sold as a percentage of net sales decreased to 66.4% during fiscal 2020
compared to 68.1% during fiscal 2019 primarily as a result of an increased percentage of product sales from ZERUST<sup>&#174;</sup>
oil and gas products, which have higher gross margins than NTIC&#8217;s traditional ZERUST<sup>&#174;</sup> industrial products
and services or its Natur-Tec<sup>&#174;</sup> products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s equity in income from joint ventures decreased 40.9% to $4,270,327 during
fiscal 2020 compared to $7,225,518 during fiscal 2019. This decrease was primarily due to a corresponding decrease in net sales
at the joint ventures, which were $87,030,062 during fiscal 2020, compared to $114,635,435 during fiscal 2019. The majority of
the decrease in sales at the joint ventures is attributable to the decrease in net sales at EXCOR, which were $32,546,402 during
fiscal 2020, compared to $47,015,841 during fiscal 2019. The decrease in the net sales of NTIC&#8217;s joint ventures was due primarily
to decreased sales to existing customers for existing products as a result of decreased demand as a result of the COVID-19 pandemic.
The decrease in net sales of NTIC&#8217;s joint ventures resulted in a corresponding decrease in fees for services provided to
joint ventures, as such fees are a function of net sales of NTIC&#8217;s joint ventures. NTIC anticipates that net sales of its
joint ventures will continue to decrease significantly as a result of decreased demand as a result of the COVID-19 pandemic and
may continue to have a significant adverse effect on NTIC&#8217;s equity in income from its joint ventures.</p>

fiscal 2019. NTIC&#8217;s earnings were significantly affected by the COVID-19 pandemic during fiscal 2020 and NTIC anticipates
that its earnings will continue to be significantly adversely affected by the COVID-19 pandemic during fiscal 2021. Additionally,
NTIC recorded a tax valuation allowance of approximately $1,600,000 against its U.S. net deferred tax asset, which had an adverse
impact on its earnings for fiscal 2020. For more information regarding this tax valuation allowance, see &#8220;<i>Part II. Item
8. Financial Statements and Supplementary Data &#8211; 14. Income Taxes</i>&#8221; of this report. NTIC anticipates that its quarterly
net income or loss will continue to remain subject to significant volatility primarily due to the financial performance of its
subsidiaries and joint ventures, sales of its ZERUST<sup>&#174;</sup> products and services into the oil and gas industry, and sales
of its Natur-Tec<sup>&#174;</sup> bioplastics products, which fluctuate more on a quarterly basis than the traditional ZERUST<sup>&#174;</sup>

<p style="font-size: 10pt; margin: 0pt 0">The following is a description of the primary components of net sales and expenses:</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Net Sales, Excluding Joint Ventures</i></b>. NTIC derives net sales from the sale
of its ZERUST<sup>&#174;</sup> products and services and its Natur-Tec<sup>&#174;</sup> products. NTIC sells its ZERUST<sup>&#174;</sup>
products and services and its Natur-Tec<sup>&#174;</sup> products either directly, through its subsidiaries, or via a network of
joint ventures, independent distributors, and agents. Net sales, excluding joint ventures represents net sales by NTIC either directly
to end users or to distributors worldwide, but not sales to NTIC&#8217;s joint ventures and not sales by NTIC&#8217;s joint ventures.
NTIC recognizes revenue from the sale of its products primarily upon shipment of the products.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Net Sales, To Joint Ventures</i></b>. Net sales, to joint ventures represents net
sales by NTIC to NTIC&#8217;s joint ventures, but not sales by NTIC either directly to end users or to distributors or sales by
NTIC&#8217;s joint ventures. NTIC&#8217;s revenue recognition policy for sales to its joint ventures is the same as NTIC&#8217;s
policy for sales to unaffiliated customers. NTIC recognizes revenue from the sale of its products to joint ventures primarily upon
shipment of the products.</p>

<!-- Field: Page; Sequence: 39; Value: 1 -->
    <div style="margin-top: 6pt; margin-bottom: 6pt; border-bottom: Black 4pt solid"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="width: 33%">&nbsp;</td><td style="width: 34%; text-align: center"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->36<!-- Field: /Sequence --></td><td style="width: 33%; text-align: right">&nbsp;</td></tr></table></div>

<p style="margin: 0pt 0; font-size: 10pt">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Cost of Goods Sold</i></b>. Most of NTIC&#8217;s products are manufactured by third
parties, and its cost of goods sold for those products consists primarily of the price invoiced by its third-party vendors. For
the portion of products that NTIC manufactures, NTIC&#8217;s cost of goods sold for those products consists primarily of direct
labor, allocated manufacturing overhead, raw materials, and components. NTIC&#8217;s margins on its Natur-Tec<sup>&#174;</sup> resin
compounds and finished products are generally smaller than its margins on its ZERUST<sup>&#174;</sup> products and services, and
NTIC&#8217;s margins on its ZERUST<sup>&#174;</sup> products and services sold into the oil and gas industry are generally greater
than its margins on its traditional ZERUST<sup>&#174;</sup> products and services.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Equity in Income from Joint Ventures</i></b>. NTIC&#8217;s equity in income from
joint ventures consists of NTIC&#8217;s share of equity in income from each joint venture based on the overall profitability of
the joint ventures. Such profitability is subject to variability from quarter to quarter, which, in turn, subjects NTIC&#8217;s
earnings to variability from quarter to quarter. Traditionally, a portion of the equity income recorded in a given fiscal year
is paid to the owners of the joint venture entity during the following fiscal year through a dividend. The payment of a dividend
by a joint venture entity is determined by a vote of the joint venture owners and is not at the sole discretion of NTIC. NTIC typically
owns only 50% or less of its joint venture entities and, thus, does not control the decisions of these entities regarding whether
to pay dividends and, if paid, how much they should be in a given year.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Fees for Services Provided to Joint Ventures</i></b>. NTIC provides certain services
to its joint ventures, including consulting, legal, travel, insurance, technical, and marketing services based on licensing or
other agreements with its joint ventures. NTIC receives fees for these services it provides to its joint ventures based primarily
on the net sales by NTIC&#8217;s joint ventures, the latter of which are not included in NTIC&#8217;s net sales reflected on NTIC&#8217;s
consolidated statements of operations. The fees for services received by NTIC from its joint ventures are generally determined
based on either a flat fee or a percentage of net sales by NTIC&#8217;s joint ventures depending on local laws and tax regulations.
With respect to EXCOR, NTIC receives an agreed upon fixed quarterly fee for such services. Under NTIC&#8217;s agreements with its
joint ventures in which the fees for services is described, amounts are earned when product is shipped from joint venture facilities,
at which point a sale is deemed to have occurred and results in obligation of the joint venture to pay the royalty and recognition
of the fee by the Company.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Selling Expenses</i></b>. Selling expenses consist primarily of sales commissions
and support costs for NTIC&#8217;s direct sale and distribution system and marketing costs.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>General and Administrative Expenses</i></b>. General and administrative expenses
consist primarily of salaries and benefits and other costs for NTIC&#8217;s executives, accounting, stock-based compensation, finance,
legal, information technology, and human resources functions.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Research and Development Expenses</i></b>. Research and development expenses include
costs associated with the design, development, market analysis, lab testing, and field trials and enhancements of NTIC&#8217;s
products and services. NTIC expenses all costs related to product research and development as incurred. Research and development
expenses reflect the net amount after being reduced by reimbursements related to certain research and development contracts. With
respect to such research and development contracts, NTIC accrues proceeds received under the contracts and offsets research and
development expenses incurred in equal installments over the timelines associated with completion of the contracts&#8217; specific
objectives and milestones.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Interest Income</i></b>. Interest income consists of interest earned on investments,
which typically consist of investment-grade, interest-bearing securities and money market accounts.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Interest Expense</i></b>. Interest expense results primarily from interest associated
with any borrowings under NTIC&#8217;s line of credit with PNC Bank.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Income Tax Expense</i></b>. Income tax expense includes federal income taxes, foreign
withholding taxes, income tax of consolidated entities in foreign jurisdictions, state income tax, and changes to NTIC&#8217;s
deferred tax valuation allowance. NTIC utilizes the asset and liability method of accounting for income taxes, which requires an
asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities
are computed annually for differences between the financial statement and tax basis of assets and liabilities that will result
in taxable or deductible amounts in the future, based on enacted tax laws and rates applicable to the periods in which the differences
are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the
amount expected to be realized. NTIC records a tax valuation allowance when it is more likely than not that some portion or all
of its deferred tax assets will not be realized. NTIC makes this determination based on all available evidence, including historical
data and projections of future results. Income tax expense is the tax payable or refundable for the period plus or minus the change
during the period in deferred tax assets and liabilities.</p>

<p style="margin: 0pt 0; font-size: 10pt">During fiscal 2020, 72.4% of NTIC&#8217;s consolidated net sales were derived from sales
of ZERUST<sup>&#174;</sup> products and services, which decreased 9.7% to $34,474,535 compared to $38,174,712 during fiscal 2019.
NTIC has strategically focused its sales efforts for ZERUST<sup>&#174;</sup> products and services on customers with sizeable corrosion
problems in industry sectors that offer sizable growth opportunities, including the oil and gas sector. Overall, demand for ZERUST<sup>&#174;</sup>
products and services depends heavily on the overall health of the market segments to which NTIC sells its products, including
the automotive, oil and gas, agriculture, and mining markets in particular. This decrease was primarily a result of reduced demand
globally as a result of the COVID-19 pandemic. NTIC anticipates that the COVID-19 pandemic will continue to significantly adversely
affect sales of ZERUST<sup>&#174;</sup> products and services during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s total ZERUST<sup>&#174;</sup> net sales decreased during fiscal 2020 compared

partially offset by increased demand for ZERUST<sup>&#174;</sup> oil and gas products and services. NTIC&#8217;s sales of ZERUST<sup>&#174;</sup>

<p style="font-size: 10pt; margin: 0pt 0">Demand for ZERUST<sup>&#174;</sup> products and services decreased significantly beginning
in February 2020 largely as a result of the COVID-19 pandemic and will likely have a significant adverse effect on sales of ZERUST<sup>&#174;</sup>
products and services during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">ZERUST<sup>&#174;</sup> oil and gas net sales increased 2.0% during fiscal 2020 compared
to fiscal 2019 primarily as a result of new opportunities with new customers, partially offset by reduced demand as a result of
the COVID-19 pandemic. The pandemic&#8217;s impact on NTIC&#8217;s ZERUST<sup>&#174;</sup> oil and gas business was primarily due
to significantly lower oil prices and travel restrictions, which inhibited NTIC&#8217;s ability to travel to customer sites in
order to install solutions. NTIC expects its oil and gas sales will continue to be impacted for the duration of the pandemic. NTIC
also anticipates that its sales of ZERUST<sup>&#174;</sup> products and services into the oil and gas industry will continue to
remain subject to significant volatility from quarter to quarter as sales are recognized, specifically due to the volatility of
oil prices. Demand for oil and gas products around the world depends primarily on market acceptance and the reach of NTIC&#8217;s
distribution network. Because of the typical size of individual orders and overall size of NTIC&#8217;s net sales derived from
sales of oil and gas products, the timing of one or more orders can materially affect NTIC&#8217;s quarterly sales compared to
prior fiscal year quarters.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">During fiscal 2020, 27.6% of NTIC&#8217;s consolidated net sales were derived from sales
of Natur-Tec<sup>&#174;</sup> products, compared to 31.5% during fiscal 2019. Sales of Natur-Tec<sup>&#174;</sup> products decreased
25.1% to $13,164,156 during fiscal 2020 compared to $17,575,425 during fiscal 2019. This decrease was primarily due to a decrease
in finished product sales in North America and finished product sales at NTIC&#8217;s majority-owned subsidiary in India, Natur-Tec
India Private Limited (Natur-Tec India), and decreased demand globally as a result of the COVID-19 pandemic. The COVID pandemic
has adversely impacted demand from across the apparel industry, as well as many large users of bioplastics, including college campuses,
stadiums, arenas, restaurants, and corporate office complexes. NTIC currently expects these customers will be some of the last
businesses to re-open, and accordingly, anticipates that the COVID-19 pandemic will continue to significantly adversely affect
sales of Natur-Tec<sup>&#174;</sup> products during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Cost of Goods Sold</i>. Cost of goods sold decreased 16.8% in fiscal 2020 compared
to fiscal 2019 primarily as a result of the decrease in net sales, as described above. Cost of goods sold as a percentage of net
sales decreased to 66.4% during fiscal 2020 compared to 68.1% during fiscal 2019 primarily due to an increased percentage of product
sales from ZERUST<sup>&#174;</sup> oil and gas products, which have higher gross margins than NTIC&#8217;s traditional ZERUST<sup>&#174;</sup>
industrial products and services or its Natur-Tec<sup>&#174;</sup> products.</p>

ventures decreased 40.9% to $4,270,327 during fiscal 2020 compared to $7,225,518 during fiscal 2019. This decrease was primarily
a result of decreased profitability of the joint ventures during fiscal 2020 compared to fiscal 2019 and which fluctuates based
on net sales. Of the total equity in income from joint ventures, NTIC had equity in income from joint ventures of $2,622,423 attributable
to EXCOR during fiscal 2020 compared to $5,415,362 attributable to EXCOR during fiscal 2019. NTIC had equity in income of all other

of 19.5%, or $1,114,694. Fee income for services provided to joint ventures is traditionally a function of the sales made by NTIC&#8217;s

services provided to joint ventures, fees of $843,752 were attributable to EXCOR during fiscal 2020 compared to $852,526 attributable
to EXCOR during fiscal 2019. These decreases are primarily the result of decreased global demand for NTIC&#8217;s products as a
result of the COVID-19 pandemic. NTIC anticipates that net sales of its joint ventures and accordingly its equity in income from
its joint ventures will continue to be adversely affected by the COVID-19 pandemic during fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Selling Expenses</i>. NTIC&#8217;s selling expenses decreased 2.8% in fiscal 2020
compared to fiscal 2019 due primarily to decreased travel expenses and other expenses due to work from home arrangements necessitated
by the COVID-19 pandemic. Selling expenses as a percentage of net sales increased to 22.4% for fiscal 2020 compared to 19.7% in
fiscal 2019 primarily due to the decrease in net sales, as previously described.</p>

decreased 7.1% in fiscal 2020 compared to fiscal 2019 primarily due to decreased travel expenses and other expenses due to work
from home arrangements necessitated by the COVID-19 pandemic, partially offset by approximately $170,000 expense due to a loss
on disposal of certain fixed assets and patents. As a percentage of net sales, general and administrative expenses increased to
18.2% for fiscal 2020 from 16.8% for fiscal 2019 primarily to the decrease in net sales, as previously described.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Income Tax Expense</i>. Income tax expense was $2,674,635 during fiscal 2020 compared
to $841,837 during fiscal 2019 for an effective tax rate of 153.7% and 12.7%, respectively. Income tax expense during fiscal 2020
includes $1,626,251 related to the impact of a tax valuation allowance recorded with respect to the Company&#8217;s domestic deferred

$0.55 per diluted common share, for fiscal 2019, a decrease of $6,547,334 or $0.70 per diluted share. This decrease was primarily
the result of the increase in the income tax expense noted above and decrease in net sales and resulting gross profit and income
from joint venture operations during fiscal 2020 compared to fiscal 2019 due to the impact of the COVID-19 pandemic.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC anticipates that its earnings will be significantly adversely affected by the COVID-19
pandemic throughout fiscal 2021 and that its quarterly net income or loss will continue to remain subject to significant volatility
primarily due to the financial performance of its subsidiaries and joint ventures, sales of its ZERUST<sup>&#174;</sup> products
and services into the oil and gas industry, and sales of its Natur-Tec<sup>&#174;</sup> bioplastics products, which fluctuate more
on a quarterly basis than the traditional ZERUST<sup>&#174;</sup> business.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Other Comprehensive Income &#8211; Foreign Currency Translations Adjustment</i>. The
changes in the foreign currency translations adjustment were due to the fluctuation of the U.S. dollar compared to the Euro and

<p style="font-size: 10pt; margin: 0pt 0"><i>Sources of Cash and Working Capital</i>. As of August 31, 2020, NTIC&#8217;s working
capital, defined as current assets less current liabilities, was $27,104,746, including $6,403,032 in cash and cash equivalents
and $5,544,722 in available for sale securities, compared to working capital of $25,460,569, including $5,856,758 in cash and cash
equivalents and $3,565,258 in available for sale securities, as of August&nbsp;31, 2019. These increases are primarily the result
of the suspension of NTIC&#8217;s quarterly cash dividend payments beginning with the third quarter of fiscal 2020, the increase
of dividends received from joint ventures, the collection of outstanding receivables and the decrease in operating expenses during
fiscal 2020 compared to fiscal 2019.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As of August 31, 2020, NTIC had a revolving line of credit with PNC Bank of $3,000,000
with no amounts outstanding. At the option of the Company, outstanding advances under the line of credit bear interest at either
(a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by the Company or (b) at the rate
publicly announced by PNC Bank from time to time as its prime rate. On December 16, 2019, the Company and PNC Bank extended the
maturity date of the line of credit from January 7, 2020 to January 7, 2021. All other terms of the line of credit and the loan
agreement and other documents evidencing the line of credit remain the same. It is anticipated that, as historically has been the
practice, the line of credit will be renewed each year for one additional year for the immediate foreseeable future.</p>

<p style="font-size: 10pt; margin: 0pt 0">The line of credit is evidenced by an amended and restated committed line of credit note
in the principal amount of up to $3,000,000. The line of credit has a $1,200,000 standby letter of credit sub-facility, with any
standby letters of credit issued thereunder being at the sole discretion of PNC Bank. Any lines of credit issued by PNC Bank would
decrease the availability under the revolving line of credit.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The line of credit is subject to standard covenants, including affirmative financial
covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things,
limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations,
and other matters customarily restricted in such agreements. Under the loan agreement, NTIC is subject to a minimum fixed charge
coverage ratio of 1.10:1.00. As of August 31, 2020, NTIC was in compliance with all debt covenants.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC believes that a combination of its existing cash and cash equivalents, available
for sale securities, forecasted cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC
for services provided to its joint ventures, and funds available through existing or anticipated financing arrangements will be
adequate to fund its existing operations, investments in new or existing joint ventures or subsidiaries, capital expenditures,
debt repayments, cash dividends if NTIC&#8217;s Board of Directors decides to reinstate them, and any stock repurchases for at
least the next 12 months. During fiscal 2021, NTIC expects to continue to invest directly and through its use of working capital
in NTIC China, Zerust Mexico, NTI Europe, research and development, marketing efforts, resources for the application of its corrosion
prevention technology in the oil and gas industry, and its Natur-Tec<sup>&#174;</sup> bio-plastics business, although the amounts
of these various investments are not known at this time. In order to take advantage of such new product and market opportunities
to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing under its revolving
line of credit or raising additional financing through the issuance of debt or equity securities. There is no assurance that any
financing transaction will be available on terms acceptable to NTIC or at all or that any financing transaction will not be dilutive
to NTIC&#8217;s current stockholders.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC traditionally has used the cash generated from its operations, distributions of
earnings from joint ventures, and fees for services provided to its joint ventures to fund NTIC&#8217;s new technology investments
and capital contributions to new and existing subsidiaries and joint ventures. NTIC&#8217;s joint ventures traditionally have operated
with little or no debt and have been self-financed with minimal initial capital investment and minimal additional capital investment
from their respective owners.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Uses of Cash and Cash Flow.</i> Net cash provided by operating activities during fiscal
2020 was $4,912,070 which resulted principally from dividends received from joint ventures, stock-based compensation, depreciation,
amortization and deferred income taxes, partially offset by NTIC&#8217;s net loss, equity in income from joint ventures, and an
offset by a decrease in accrued liabilities. Net cash provided by operating activities during fiscal 2019 was $5,477,022, which
resulted principally from NTIC&#8217;s net income, dividends received from joint ventures, stock-based compensation, depreciation,
amortization, and an increase in accounts payable, partially offset by NTIC&#8217;s equity in income from joint ventures, an increase
in inventory and a decrease in accrued liabilities.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s cash flows from operations are impacted by significant changes in certain
components of NTIC&#8217;s working capital, including inventory turnover and changes in receivables and payables. NTIC considers
internal and external factors when assessing the use of its available working capital, specifically when determining inventory
levels and credit terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts,
and customer requested payment terms, and key external factors include the availability of primary raw materials and sub-contractor
production lead times. NTIC&#8217;s typical contractual for trade receivables, excluding joint ventures, are traditionally 30 days
and 90 days for trade receivables from its joint ventures. Before extending unsecured credit to customers, excluding NTIC&#8217;s
joint ventures, NTIC reviews customers&#8217; credit histories and will establish an allowance for uncollectible accounts based
upon factors surrounding the credit risk of specific customers and other information. Accounts receivable over 30 days are considered
past due for most customers. NTIC does not accrue interest on past due accounts receivable. If accounts receivables in excess of
the provided allowance are determined uncollectible, they are charged to selling expense in the period that the determination is
made. Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC&#8217;s typical
contractual terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services
provided to its joint ventures on an accrual basis, unless circumstances exist that make the collection of the balance uncertain,
in which case the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled
on a case by case basis.</p>

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Inflation in the United States and abroad historically has had little effect on NTIC.
Although NTIC&#8217;s business historically has not been seasonal, NTIC believes there is now some seasonality in its business.
NTIC believes its net sales in the second fiscal quarter were adversely affected by the long Chinese New Year, which slowdown was
extended in an effort to combat the spread of COVID-19, the North American holiday season, and overall less corrosion taking place
at lower winter temperatures worldwide.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC is exposed to market risk stemming from changes in foreign currency exchange rates,
commodity prices, and interest rates.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Because the functional currency of NTIC&#8217;s foreign operations and investments in
its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from
transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese Yen,
the Indian Rupee, the Chinese Renminbi, the South Korean Won, and the English Pound against the U.S. Dollar. NTIC&#8217;s fees
for services provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and,
thus, fluctuations in foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since NTIC&#8217;s
investments in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would
be reflected as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income from joint ventures
reflected in its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font-size: 10pt; margin: 0pt 0">At the option of NTIC, outstanding advances under NTIC&#8217;s $3,000,000 revolving line
of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest
period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate and, thus, may subject
NTIC to some market risk on interest rates. As of August 31, 2020, NTIC had no borrowings under the line of credit.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC established its joint venture network approximately 30 years ago as a method to
increase its worldwide distribution network for ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products and services. NTIC
participates, either directly or indirectly, in 19 active joint venture arrangements in North America, Europe, and Asia. Each of
these joint ventures generally manufactures and markets finished products in the geographic territory to which it is assigned.
NTIC&#8217;s joint venture partners are knowledgeable in the applicable environmental, labor, tax, and other requisite regulations
and laws of the respective foreign countries in which they operate, as well as the local customs and business practices. NTIC&#8217;s
revenue recognition policy for sales to its joint ventures is the same as its policy for sales to unaffiliated customers.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The fees for services provided to joint ventures are determined based on either a flat
fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s joint venture in Germany,
EXCOR, NTIC recognizes an agreed upon quarterly fee for such services. NTIC records revenue related to fees for services provided
to joint ventures when earned, amounts are determinable, and collectability is reasonably assured. Under NTIC&#8217;s agreements
with its joint ventures, fee amounts are earned when product is shipped from joint venture facilities. NTIC reviews the financial
situation of each joint venture to assist in the likelihood of collections on amounts earned. From time to time, NTIC elects to
account for such fees on a cash basis for certain joint ventures when uncertainty exists surrounding the collections of such fees.
There are no fees being accounted for in this manner at present. The expenses incurred in support of its joint ventures are direct
expenses that NTIC incurs related to its joint ventures and include such items as employee compensation and benefit expenses, travel
expense, insurance, consulting expense, legal expense, and lab supplies and testing expense.</p>

such as entities often referred to as structured finance or special purpose entities, which are established for the purpose of

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The preparation of NTIC&#8217;s consolidated financial statements requires management
to make estimates and judgments that affect the reported amount of assets, liabilities, revenues and expenses, and related disclosure
of contingent assets and liabilities. The Securities and Exchange Commission has defined a company&#8217;s most critical accounting
policies as those that are most important to the portrayal of its financial condition and results of operations and those which
require the company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters
that are inherently uncertain. Based on this definition, NTIC has identified the following critical accounting policies. Although
NTIC believes that its estimates and assumptions are reasonable, they are based upon information available when they are made.
Actual results may differ significantly from these estimates under different assumptions or conditions.</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Principles of Consolidation </i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC evaluates its voting and variable interests in entities on a qualitative and quantitative
basis. NTIC consolidates entities in which it concludes it has the power to direct the activities that most significantly impact
an entity&#8217;s economic success and has the obligation to absorb losses or the right to receive benefits that could be significant
to the entity. All such relationships are evaluated on an ongoing basis. The consolidated financial statements include the accounts
of Northern Technologies International Corporation, its wholly-owned subsidiaries, Northern Technologies Holding Company, LLC,
NTIC (Shanghai) Co., Ltd., NTIC Europe GmbH and ZERUST-EXCOR MEXICO, S. de R.L. de C.V., NTIC&#8217;s majority-owned subsidiary
in Brazil, Zerust Preven&#231;&#227;o de Corros&#227;o S.A., NTIC&#8217;s majority-owned holding company, NTI Asean LLC,
and NTIC&#8217;s majority-owned subsidiary in India, Natur-Tec India Private Limited, Natur-Tec Lanka, Zerust Singapore Pte Ltd
(Zerust Singapore) and Zerust Vietnam Co. Ltd (Zerust Vietnam). NTIC&#8217;s consolidated financial statements do not include the
accounts of any of its joint ventures.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s investments in its joint ventures are accounted for using the equity method.
NTIC assesses its joint ventures for impairment on an annual basis as of August 31 of each year as part of its fiscal year end
analysis. In addition to the annual review for impairment, NTIC reviews the operating results of each joint venture on a quarterly
basis in comparison to its historical operating results and its accrual for fees for services provided to joint ventures. If the
operating results of a joint venture do not meet NTIC&#8217;s financial performance expectations, an additional evaluation is performed
on the joint venture. In addition to the annual assessments for impairment, non-periodic assessments for impairment may occur if
cash remittances are less than accrued balances, a joint venture&#8217;s management requests capital, or other events occur suggesting
anything other than temporary decline in value. If an investment were determined to be impaired, then a reserve would be created
to reflect the impairment on the financial results of NTIC. NTIC&#8217;s evaluation of its investments in joint ventures requires
NTIC to make assumptions about future cash flows of its joint ventures. These assumptions require significant judgment, and actual
results may differ from assumed or estimated amounts.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Investment at Carrying Value </i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">If NTIC is no longer able to exercise significant influence over operating and financial
policy of a joint venture previously accounted for under the equity method, it maintains the investment at the carrying value as
of the date that significant influence no longer exists and discontinues accruing the proportionate earnings or losses of the investment.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Investments are considered to be impaired when a decline in fair value is judged to be
other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by
management. NTIC employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence
in evaluating potential impairment of its investments. If the cost of an investment exceeds its fair value, NTIC evaluates, among
other factors, general market conditions, credit quality of debt instrument issuers, the duration and extent to which the fair
value is less than cost, and for equity securities, its intent and ability to hold, or plans to sell, the investment. NTIC also
considers specific adverse conditions related to the financial health of and business outlook for the investee, including industry
and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair value is
determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis in the
investment is established.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><b><i>Revenue Recognition</i></b></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Revenue is measured based on consideration specified in the contract with a customer,
adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including noncash
consideration, consideration paid or payable to customers, and significant financing components. While most of the Company&#8217;s
revenue is contracted with customers through one-time purchase orders and short-term contracts, the Company does have long-term
arrangements with certain customers. Revenue from all customers is recognized when a performance obligation is satisfied by transferring
control of a distinct good or service to a customer. The transaction price for the Company&#8217;s products is the invoiced amount.
Revenue is recognized when transfer of control occurs as defined by the terms in the customer agreement, generally upon shipment
of product.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">With respect to recording revenue related to fees earned for services provided to NTIC&#8217;s
joint ventures, amounts are earned when product is shipped from joint venture facilities, at which point a sale is deemed to have
occurred and results in obligation for the joint venture to pay the royalty and recognition of the fee by the Company. The support
and services NTIC provides its joint ventures include consulting, travel, insurance, technical and marketing services to existing
joint ventures, legal fees incurred in the establishment of new joint ventures, registration and promotion and legal defense of
worldwide trademarks, and legal fees incurred in connection with the filing of patent applications based on licensing or other
agreements with its joint ventures. NTIC receives fees for the services it provides to its joint ventures based primarily on the
net sales by NTIC&#8217;s joint ventures. The fees for support services received by NTIC from its joint ventures are generally
determined based on either a flat fee or a percentage of net sales by NTIC&#8217;s joint ventures depending on local laws and tax
regulations. Under NTIC&#8217;s agreements with its joint ventures, amounts are earned when product is shipped from joint venture
facilities. NTIC reviews the financial situation of each of its joint ventures to assist in the likelihood of collections on amounts
earned. NTIC elects to account for these fees on a cash basis for certain joint ventures when uncertainty exists surrounding the
collections of such fees.</p>

<p style="font-size: 10pt; margin: 0pt 0">Trade receivables arise from sales of NTIC&#8217;s products and services to NTIC&#8217;s
joint ventures and to unaffiliated customers. Trade receivables from joint ventures arise from sales NTIC makes to its joint ventures
of products and the essential additives required to make ZERUST<sup>&#174;</sup> industrial corrosion inhibiting products functional.
Receivables for services to NTIC&#8217;s joint ventures are contractually based primarily on a percentage of the sales of the joint
ventures and are intended to compensate NTIC for services NTIC provides to its joint ventures, including consulting, legal, travel,
insurance, technical, and marketing services.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Payment terms for NTIC&#8217;s unaffiliated customers are determined based on credit
risk and vary by customer. NTIC typically offers standard payment terms of net 30 days to unaffiliated customers. Payment terms
for NTIC&#8217;s joint ventures also are determined based on credit risk; however, additional consideration is given to the individual
joint venture due to the transportation time associated with ocean delivery of most products and certain other factors. NTIC typically
offers payment terms to joint ventures of net 90 days. NTIC does not accrue interest on past due accounts receivable. NTIC reviews
the credit histories of its customers, including its joint ventures, before extending unsecured credit. NTIC values accounts and
notes receivable net of an allowance for doubtful accounts. Each quarter, NTIC prepares an analysis of its ability to collect outstanding
receivables that provides a basis for an allowance estimate for doubtful accounts. In doing so, NTIC evaluates the age of its receivables,
past collection history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on
this evaluation, NTIC establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well
as an estimate of uncollectible receivables not specifically known. Deterioration in the financial condition of any key customer
or joint venture or a significant slowdown in the economy could have a material negative impact on NTIC&#8217;s ability to collect
a portion or all of the accounts and notes receivable. NTIC believes that an analysis of historical trends and its current knowledge
of potential collection problems provide NTIC with sufficient information to establish a reasonable estimate for an allowance for
doubtful accounts. However, since NTIC cannot predict with certainty future changes in the financial stability of its customers
or joint ventures, NTIC&#8217;s actual future losses from uncollectible accounts may differ from its estimates. In the event NTIC
determined that a smaller or larger uncollectible accounts reserve is appropriate, NTIC would record a credit or charge to selling
expense in the period that it made such a determination.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC reviews its long-lived assets whenever events or changes in circumstances indicate
the carrying amount of the assets may not be recoverable and determines potential impairment by comparing the carrying value of
the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If
the sum of the expected undiscounted future net cash flows were less than the carrying value, NTIC would determine whether an impairment
loss should be recognized. An impairment loss would be measured by comparing the amount by which the carrying value exceeds the
fair value of the asset.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The functional currency of each international joint venture and subsidiary is the applicable
local currency. The translation of the applicable foreign currencies into U.S. dollars is performed for balance sheet accounts
using exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average monthly exchange
rate. Translation gains or losses are reported as an element of accumulated other comprehensive (loss) income.</p>

Zerust Singapore, Zerust Vietnam, Zerust Mexico, NTI Europe, and NTIC&#8217;s joint ventures) conducts all foreign transactions
based on the U.S. dollar. Since NTIC&#8217;s investments in its joint ventures are accounted for using the equity method, any changes
in foreign currency exchange rates would be reflected as a foreign currency translation adjustment and would not change the equity
in income from joint ventures reflected in NTIC&#8217;s consolidated statements of operations.</p>

grants of employee stock options and transactions under NTIC&#8217;s employee stock purchase plan, in its consolidated financial
statements. That cost is measured based on the fair value of the equity or liability instruments issued. NTIC measures the cost
of employee services received in exchange for stock options or other stock-based awards based on the grant-date fair value of the
award and recognizes the cost over the period the employee is required to provide services for the award.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s inventories consist primarily of production materials and finished goods.
NTIC purchases production materials and finished goods based on forecasted demand and records inventory at the lower of cost or
net realizable value. Cost is determined by the first-in, first-out (FIFO) method. Management regularly assesses inventory valuation
based on current and forecasted usage, demand and pricing, shelf life, customer inventory-related contractual obligations, and
other considerations. If actual results differ from management estimates with respect to the actual or projected selling of inventories
at amounts less than their carrying amounts, NTIC would adjust its inventory balances accordingly.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC utilizes the asset and liability method of accounting for income taxes, which requires
the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included
in the consolidated financial statements. Deferred income tax assets and liabilities are determined based on the differences between
the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences
are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in operations
in the period that includes the enactment date.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC records net deferred tax assets to the extent NTIC believes these assets will more
likely than not be realized. In making such a determination, NTIC considers all available positive and negative evidence, including
future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results
of recent operations, including the prior three-year history. In the event NTIC determines that it would be able to realize its
deferred income tax assets in the future in excess of their net recorded amount, NTIC makes an adjustment to the deferred tax asset
valuation allowance, which would reduce the provision for income taxes.</p>

rates, commodity prices, and interest rates.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Because the functional currency of NTIC&#8217;s foreign operations and investments in
its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from
transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro, the Japanese Yen,
the Indian Rupee, the Chinese Renminbi, the South Korean Won, and the English Pound against the U.S. Dollar. NTIC&#8217;s fees
for services provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies,
and, thus, fluctuations in foreign currency exchange rates could result in declines in NTIC&#8217;s reported net income. Since
NTIC&#8217;s investments in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange
rates would be reflected as a foreign currency translation adjustment and would not change NTIC&#8217;s equity in income from joint
ventures reflected in its consolidated statements of operations. NTIC does not hedge against its foreign currency exchange rate
risk.</p>

of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest
period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate and, thus, may subject
NTIC to some market risk on interest rates. As of August 31, 2020, NTIC had no borrowings under the line of credit.</p>

International Corporation and Subsidiaries (the "Company") as of August 31, 2020 and 2019, the related consolidated statements
of operations, comprehensive income (loss), equity, and cash flows, for each of the two years in the period ended August 31, 2020,
and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of August 31, 2020 and
2019, and the results of its operations and its cash flows for each of the two years in the period ended August 31, 2020, in conformity

<p style="font-size: 10pt; margin: 0pt 0">These consolidated financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public
accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required
to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">We conducted our audits in accordance with the standards of the PCAOB. Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are
free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform,
an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's
internal control over financial reporting. Accordingly, we express no such opinion.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Our audits included performing procedures to assess the risks of material misstatement
of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as
well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable
basis for our opinion.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Nature of Business </i>&#8211; Northern Technologies International Corporation and
its Subsidiaries (collectively, the Company) develop and market proprietary environmentally beneficial products and services in
over 60 countries either directly or via a network of joint ventures, independent distributors, and agents. The Company&#8217;s
primary business is corrosion prevention marketed mainly under the ZERUST<sup>&#174;</sup> brand. The Company has been selling its
proprietary ZERUST<sup>&#174;</sup> rust and corrosion inhibiting products and services to the automotive, electronics, electrical,
mechanical, military, and retail consumer markets for over 40 years and, more recently, has targeted and expanded into the oil
and gas industry. The Company also sells a portfolio of bio-based and certified compostable (fully biodegradable) polymer resin
compounds and finished products under the Natur-Tec<sup>&#174;</sup> brand. These products are intended to reduce the Company&#8217;s
customers&#8217; carbon footprint and provide environmentally sound disposal options. The Company&#8217;s two operating segments
are ZERUST and Natur-Tec.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company participates, either directly or indirectly, in 19 active joint venture arrangements
in North America, Europe, and Asia. Each of these joint ventures generally manufactures and markets products in the geographic
territory to which it is assigned. While most of the Company&#8217;s joint ventures exclusively sell rust and corrosion inhibiting
products, some of the joint ventures also sell the Company&#8217;s Natur-Tec<sup>&#174;</sup> resin compounds and finished products.
The profits of joint ventures are shared by the respective joint venture owners in accordance with their respective ownership percentages.
The Company typically owns 50% or less of its joint venture entities and does not control the decisions of these entities, including
dividend declaration or amount in any given year.</p>

declared the novel coronavirus (COVID-19) outbreak a global pandemic. As a result of the COVID-19 pandemic and related government
mandated restrictions on the Company&#8217;s business as well as the businesses of its joint ventures, customers and suppliers,
disruption to the Company&#8217;s business and the manufacture and sale of its products and services has occurred and is expected
to continue into fiscal 2021.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Principles of Consolidation</i> &#8211; NTIC evaluates its voting and variable interests
in entities on a qualitative and quantitative basis. NTIC consolidates entities in which it concludes it has the power to direct
the activities that most significantly impact an entity&#8217;s economic success and has the obligation to absorb losses or the
right to receive benefits that could be significant to the entity. The consolidated financial statements include the accounts of
Northern Technologies International Corporation, its wholly-owned subsidiaries, Northern Technologies Holding Company, LLC, NTIC
(Shanghai) Co., Ltd. (NTIC China), ZERUST-EXCOR MEXICO, S. de R.L. de C.V (Zerust Mexico), NTIC Europe GmbH (NTI Europe), NTIC&#8217;s

Brazil, Zerust Preven&#231;&#227;o de Corros&#227;o S.A. (Zerust Brazil), NTIC&#8217;s majority-owned subsidiary in Sri Lanka,
Natur Tec Lanka (Pvt) Ltd (Natur Tec Lanka), and NTIC&#8217;s majority-owned holding company, NTI Asean LLC (NTI Asean), Zerust
Singapore Pte Ltd (Zerust Singapore) and Zerust Vietnam Co. Ltd (Zerust Vietnam). NTIC&#8217;s consolidated financial statements
do not include the accounts of any of its joint ventures.</p>

of Natur Tec Lanka, 85% of Zerust Brazil, 60% of NTI Asean, 60% of Zerust Singapore Pte Ltd, and 60% of Zerust Vietnam Co. Ltd.&nbsp;
The remaining ownership of the consolidated entities are accounted for as non-controlling interests and reported as part of equity
in the consolidated financial statements. The Company allocates gains and losses to the non-controlling interest even when such
allocation results in a deficit balance, reducing the losses attributed to the controlling interest. Changes in ownership interests
are treated as equity transactions if the Company maintains control.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Net Sales </i>&#8211; The Company includes net sales to its joint ventures and net
sales to unaffiliated customers as separate line items on its consolidated statements of operations. There are no sales originating
from the Company&#8217;s joint ventures included in the amount, as the Company&#8217;s investments in its joint ventures are accounted
for using the equity method.</p>

<p style="margin: 0pt 0; font-size: 10pt">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">In May 2014, the Financial Accounting Standards Board (FASB) issued guidance creating
Accounting Standards Codification (ASC) Section 606, <i>Revenue from Contracts with Customers</i> (ASC 606), which establishes
a comprehensive new model for the recognition of revenue from contracts with customers. This model is based on the core principle
that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects
the consideration to which the entity expects to be entitled in exchange for those goods or services.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">On September 1, 2018, the Company adopted ASC 606 for all customer contracts using the
modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs
the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract;
(3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5)
recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the five-step model to contracts
when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to,
or services it performs for, the customer.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The adoption of ASC 606 did not impact the previously reported financial statements in
any prior period or result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did
not impact the Company&#8217;s revenue recognition process. Generally, the Company&#8217;s performance obligations are satisfied
when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the
terms of the contracts. The Company&#8217;s services are generally sold based upon quotes or contracts with customers that include
a fixed or determinable price, and sales arrangements do not contain any significant financing component for its customers. The
Company does not recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer
arrangements do not generate contract assets or liabilities.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Changes to the Company&#8217;s significant accounting policies as a result of adopting
ASC 606 are discussed below.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Revenue Recognition</i> &#8211; Revenue is measured based on consideration specified
in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the
transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components.
Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good
or service to a customer.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Individually promised goods and services in a contract are considered a distinct performance
obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other
resources that are readily available to the customer and the good or service is separately identifiable from other promises in
the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance
obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the
period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing
overhead, materials, and components. The Company does not incur significant upfront costs to obtain a contract. If costs to obtain
a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with
the related recognition of revenue.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company excludes government assessed and imposed taxes on revenue generating transactions
that are invoiced to customers from revenue. The Company includes freight billed to customers in revenue. Shipping and handling
costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment
cost and are included in cost of goods sold.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The timing of revenue recognition, billing, and cash collections results in accounts
receivable on the consolidated balance sheet.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Performance Obligations</i> - A performance obligation is a promise in a contract
to transfer a distinct good or service to the customer. A contract&#8217;s transaction price is allocated to each distinct performance
obligation in proportion to its standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied.
The Company&#8217;s various performance obligations and the timing or method of revenue recognition are discussed below. The Company&#8217;s

<p style="font-size: 10pt; margin: 0pt 0">The Company sells its products to both distributors and end-users. Each unit of product
delivered under a customer order represents a distinct and separate performance obligation, as the customer can benefit from each
unit on its own or with other resources that are readily available to the customer, and each unit of product is separately identifiable
from other products in the arrangement.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The transaction price for the Company&#8217;s products is the invoiced amount. The Company
does not have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other
items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone
selling price; therefore, the Company does not need to allocate proceeds on a relative standalone selling price allocation between
performance obligations. The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information
about remaining performance obligations that have original expected durations of one year or less. There are no material obligations
that extend beyond one year.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Revenue is recognized when transfer of control occurs, as defined by the terms in the
customer agreement. The Company immediately recognizes incidental items that are immaterial in the context of the contract. The
Company has applied the practical expedient in paragraph 606-10-25-16A and does not assess if immaterial items are promised goods
or services. The Company has also applied the practical expedient in paragraph 606-10-32-18 regarding the adjustment of the promised
amount of consideration for the effects of a significant financing component when the customer pays for that good or service within
one year or less, as the Company does not have any significant financing components in its customer arrangements since payment
is received at or shortly after the point of sale, generally thirty to ninety days.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company estimates returns based on an analysis of historical experience if the right
to return products is granted to its customers. The Company does not record a return asset, as non-conforming products are generally
not returned. The Company&#8217;s return policy does not vary by geography. The customer has no rotation or price protection rights,
and the Company is not under a warranty obligation.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Sales Commissions</i> &#8211; Sales commissions paid to sales representatives are
eligible for capitalization, as they are incremental costs that would not have been incurred without entering into a specific sales
arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical
expedient provided by ASC 340-40-25-4 and recognize the incremental costs of obtaining contracts as an expense when incurred, as
the amortization period of the assets that would have otherwise been recognized is one year or less. The Company records these
costs as a selling expense.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Product Warranty</i> &#8211; The Company offers warranties on various products and
services. These warranties are assurance type warranties that are not sold on a standalone basis; therefore, they are not considered
distinct performance obligations. The Company estimates the costs that may be incurred under its warranties and records a liability
in the amount of such costs at the time the revenue is recognized for the product sale.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>International Revenue</i> &#8211; The Company markets its products to numerous countries

<p style="font-size: 10pt; margin: 0pt 0"><i>Trade Receivables</i> &#8211; Payment terms for the Company&#8217;s unaffiliated customers
are determined based on credit risk and vary by customer. The Company typically offers standard payment terms to unaffiliated customers
of net 30 days. The Company does not accrue interest on past due accounts receivable. The Company reviews the credit histories
of its customers before extending unsecured credit. The Company presents accounts and notes receivable net of an allowance for
doubtful accounts. Each quarter, the Company prepares an analysis of its ability to collect outstanding receivables that provides
a basis for an allowance estimate for doubtful accounts. In doing so, the Company evaluates the age of its receivables, past collection
history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on this evaluation,
the Company establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well as an
estimate of uncollectible receivables not specifically known. The Company believes that an analysis of historical trends and its
current knowledge of potential collection problems provide the Company with sufficient information to establish a reasonable estimate
for an allowance for doubtful accounts. In the event the Company determines that a smaller or larger uncollectible accounts reserve
is appropriate, the Company records a credit or charge to selling expense in the period that it made such determination. Accounts
receivable have been reduced by an allowance for uncollectible accounts of $90,000 as of August 31, 2020 and $65,000 as of August
31, 2019. Accounts are considered past due based on terms agreed upon between the Company and the customer. Accounts receivable
are written-off only after all collection attempts have failed and are based on individual credit evaluation and specific circumstances
of the customer.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Trade Receivables from Joint Ventures </i>&#8211; Trade receivables from joint ventures
arise from sales of products the Company makes to its joint ventures. Payment terms for the Company&#8217;s joint ventures also
are determined based on credit risk; however, additional consideration is given to the individual joint venture due to the transportation
time associated with ocean delivery of most products and certain other factors. Generally, accounts receivable from the Company&#8217;s
joint ventures unpaid after 90 days are considered past due. The Company does not accrue interest on past due balances. The Company
periodically reviews amounts due from its joint ventures for collectability and, based on past experience and continuous review
of the balances due, determined that an allowance for doubtful accounts related to its joint venture receivables was not necessary
as of August 31, 2020 or 2019.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Fees for Services Provided to Joint Ventures &#8211; </i>The Company provides services
to its joint ventures including consulting, legal, travel, insurance, technical, and marketing services based on licensing or other
agreements with its joint ventures. The Company receives fees for the services it provides to its joint ventures. The fees for
services received by the Company from its joint ventures are generally based on either a flat fee or a percentage of net sales
by the Company&#8217;s joint ventures depending on local laws and tax regulations. Under the Company&#8217;s agreements with its
joint ventures, amounts are earned when product is shipped from joint venture facilities, at which point a sale is deemed to have
occurred and results in obligation for the joint venture to pay the royalty and recognition of the fee by the Company. The Company
reviews the financial situation of each of its joint ventures to assist in the likelihood of collections on amounts earned. The
Company accounts for these fees on a cash basis if uncertainty exists surrounding the collection of such fees.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Cash and Cash Equivalents</i> &#8211; The Company includes as cash and cash equivalents
highly liquid, short-term investments with maturity of three months or less when purchased, which are readily convertible into
known amounts of cash. The Company maintains its cash in high quality financial institutions. The balances, at times, may exceed
federally insured limits.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Patents and Trademarks</i> &#8211; Patents and trademarks, including acquisition costs,
are stated at cost, less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful
lives of the respective assets. Upon retirement, the cost of assets disposed and the related accumulated amortization are removed
from the accounts, and any resulting gain or loss is credited or charged to operations.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Investments in Joint Ventures</i> &#8211; Investments in the Company&#8217;s joint
ventures are accounted for using the equity method. Under the equity method, investments are initially recorded at cost and are
adjusted for dividends, distributed and undistributed earnings and losses, changes in foreign currency exchange rates, and additional
investments. In the event the Company&#8217;s share of a joint venture&#8217;s cumulative losses exceeds the Company&#8217;s investment
balance, the balance is reported at zero value until proportionate income exceeds the losses. The Company assesses its joint ventures
for impairment on an annual basis as of August 31 of each year as part of its fiscal year end analysis. In addition to the annual
review for impairment, the Company reviews the operating results of each joint venture on a quarterly basis in comparison to its
historical operating results and its accrual of fees for services provided to joint ventures. If the operating results of a joint
venture do not meet financial performance expectations, an additional evaluation is performed on the joint venture. The Company&#8217;s
evaluation of its investments in joint ventures requires the Company to make assumptions about future cash flows of its joint ventures.
These assumptions require significant judgment, and actual results may differ from assumed or estimated amounts. All investments
in joint ventures had positive equity as of August 31, 2020 and 2019. The Company considers any of its joint ventures to be significant
and discloses entity specific financial information if the joint venture&#8217;s income or assets make up more than 20% of the
Company&#8217;s total assets or income.</p>

<p style="font-size: 10pt; margin: 0pt 0">If the Company is no longer able to exercise significant influence over operating and

<p style="font-size: 10pt; margin: 0pt 0">Investments are considered to be impaired when a decline in fair value is judged to be
other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by
management. The Company employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative
evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, the Company
evaluates, among other factors, general market conditions, credit quality, the duration and extent to which the fair value is less
than cost, and for equity securities, the Company&#8217;s intent and ability to hold, or plans to sell, the investment. The Company
also considers specific adverse conditions related to the financial health of and business outlook for the investee, including
industry and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair
value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis
in the investment is established.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Recoverability of Long-Lived Assets</i> &#8211; The Company reviews its long-lived
assets whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. The Company
determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided
by operating activities of the business or related products. If the sum of the expected undiscounted future net cash flows is less
than the carrying value, the Company evaluates whether an impairment loss should be recognized. An impairment loss is measured
by comparing the amount by which the carrying value exceeds the fair value of the asset. When evaluating assets for impairment,
the Company groups long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are
largely independent of the cash flows of other assets and liabilities.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Income Taxes </i>&#8211; The Company utilizes the asset and liability method of accounting
for income taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences
of events that have been included in the consolidated financial statements. Deferred income tax assets and liabilities are determined
based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect
for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities
is recognized in operations in the period that includes the enactment date.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company records net deferred tax assets to the extent the Company believes these
assets will more likely than not be realized. In making such a determination, the Company considers all available positive and
negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning
strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred
assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation
allowance, which would reduce the provision for income taxes.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company records uncertain tax positions on the basis of a two-step process whereby
the Company determines whether it is more likely than not that the tax positions will be sustained based on the technical merits
of the position and those tax positions that meet the more-likely-than-not recognition threshold. The Company recognizes the largest
amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority.</p>

Tax Cuts and Jobs Act (Tax Reform Act) that are stranded in accumulated other comprehensive income. This standard also requires
certain disclosures about stranded tax effects. ASU No. 2018-02, however, does not change the underlying guidance that requires
that the effect of a change in tax laws or rates be included in income from continuing operations. ASU No. 2018-02 was adopted

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company adopted the new leasing standards on September 1, 2019, using a modified
retrospective transition approach to be applied to leases existing as of, or entered into after, September 1, 2019; and, consequently,
financial information will not be updated and the disclosures required under Topic 842 will not be provided for dates and periods
prior to September 1, 2019. The Company has reviewed its existing lease contracts and the impact of the new leasing standards on
its consolidated results of operations, financial position and disclosures. Upon adoption of the new leasing standards, the Company
recognized a lease liability and related right-of-use asset on its consolidated balance sheet of approximately $600,000 as of September
1, 2019.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>New Accounting Pronouncements Not Yet Adopted</i></p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial
Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November
2018, issued ASU No. 2018-19 and in April 2019, issued ASU No. 2019-04 and in May 2019, issued ASU No. 2019-05, and in November
2019, issued ASU No. 2019-11, which amended the standard. The new standard introduces an approach, based on expected losses, to
estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt
securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most
financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity
debt securities, net investments in leases and off-balance-sheet credit exposures. This ASU is effective for fiscal years beginning
after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. Entities are required
to apply the standard&#8217;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first
reporting period in which the guidance is adopted. The Company is still evaluating the impact of this ASU.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">Although there are several other new accounting pronouncements issued or proposed by
the FASB, which the Company has adopted or will adopt, as applicable, the Company does not believe any of these accounting pronouncements
has had or will have a material impact on the Company&#8217;s consolidated financial position or operating results.</p>

of $3,000,000. No amounts were outstanding under the line of credit as of both August 31, 2020 and 2019. At the option of the Company,
outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable
LIBOR interest period selected by the Company or (b) at the rate publicly announced by PNC Bank from time to time as its prime
rate.</p>

<p style="font-size: 10pt; margin: 0pt 0">The line of credit is governed under a loan agreement. The loan agreement contains standard
covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative
covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition
of assets, mergers and consolidations, and other matters customarily restricted in such agreements. Under the loan agreement, the
Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00. As of August 31, 2020, the Company was in compliance
with all debt covenants.</p>

as of August 31, 2020 and 2019 with PNC Bank. The availability of advances under the line of credit will be reduced by the face
amount of any letter of credit issued and outstanding (whether or not drawn) under the revolving credit facility.&nbsp;</p>

of the Company&#8217;s common stock exceeded the exercise price of the potentially dilutive option securities granted. Net income
per common share was based on the weighted average number of common shares outstanding during the periods when computing the basic
net income per share. When dilutive, stock options are included as equivalents using the treasury stock market method when computing
the diluted net income per share. Excluded from the computation of diluted net income per share as of August 31, 2020 were options
outstanding to purchase 1,127,968 shares of common stock due to the net loss for the period. Excluded from the computation of diluted
net income per share as of August 31, 2019 were options outstanding to purchase 141,768 shares of common stock.</p>

stock-based awards have been granted: the Northern Technologies International Corporation 2019 Stock Incentive Plan (the 2019 Plan),
which was approved by stockholders at the 2019 annual meeting of stockholders, the Northern Technologies International Corporation
Amended and Restated 2007 Stock Incentive Plan (the 2007 Plan) and the Northern Technologies International Corporation Employee
Stock Purchase Plan (the ESPP). The 2019 Plan replaced the 2007 Plan with respect to future grants; and, therefore, no further
awards may be made under the 2007 Plan. The Compensation Committee of the Board of Directors and the Board of Directors administer
these plans.</p>

<p style="font-size: 10pt; margin: 0pt 0">The 2019 Plan provides for the grant of incentive stock options, non-statutory stock
options, stock appreciation rights, restricted stock, stock unit awards, performance awards, and stock bonuses to eligible recipients
to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation
in the Company and to reward those individuals who contribute to the achievement of the Company&#8217;s economic objectives. Subject
to adjustment as provided in the 2019 Plan, up to a maximum of 800,000 shares of the Company&#8217;s common stock are issuable
under the 2019 Plan. Options granted generally have a term of ten years and become exercisable over a one- or three- year period
beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market
value of the Company&#8217;s common stock on the date of grant. The Company issues new shares upon the exercise of options. During
the fiscal years ended August 31, 2020 and 2019, the Company granted stock options under the 2019 Plan to purchase an aggregate
of 300,770 and 141,767 shares of its common stock to various employees and directors, respectively. As of August 31, 2020, 499,230
shares of common stock remained available under the 2019 Plan.</p>

<p style="font-size: 10pt; margin: 0pt 0">The maximum number of shares of common stock of the Company available for issuance under
the ESPP is 200,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning
on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common
stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans
of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting
purposes. The Company issued 2,754 and 2,462 shares on March 1, 2020 and 2019, respectively, and 3,597 and 1,748 shares on September
1, 2019 and 2018, respectively, under the ESPP. As of August 31, 2020, 84,693 shares of common stock remained available for sale
under the ESPP.</p>

<p style="font-size: 10pt; margin: 0pt 0">The fair value of option grants is determined at the date of grant using the Black-Scholes
option pricing model with the assumptions listed below.&nbsp; The volatility factor used in the Black-Scholes option pricing model
is based on historical stock price fluctuations, and the risk-free interest rate is based on U.S. treasury rates appropriate for
the expected term. Dividend yield and expected volatility are estimated using historical amounts that are anticipated to be consistent
with current values. Expected life of the option is based on the life of the option agreements. Based on these valuations, the
Company recognized compensation expense of $1,337,774 and $1,431,925 during fiscal 2020 and fiscal 2019, respectively, related
to the options that vested during such time. As of August&nbsp;31, 2020, the total compensation cost for non-vested options not
yet recognized on the Company&#8217;s consolidated statements of operations was $20,834, which is expected to be recognized during
fiscal 2021, based on outstanding options as of August 31, 2020. Future option grants will impact the compensation expense recognized.
Stock-based compensation expense is included in general and administrative expense on the consolidated statements of operations.</p>

to its portion of the cumulative undistributed earnings of certain foreign subsidiaries and joint ventures that are essentially
permanent in duration. As a result of the 2017 tax law changes, U.S. federal income taxes on dividends received from the Company&#8217;s
foreign subsidiaries and joint ventures after December 31, 2017 have been generally eliminated. However, the Company continues
to be subject to foreign withholding taxes upon repatriation of any undistributed earnings that are not essentially permanent in
duration. The Company recorded a tax benefit of approximately $76,000 and tax expense of approximately $4,000 during fiscal 2020
and fiscal 2019, respectively, representing changes in the deferred tax liability for foreign withholding taxes to be paid with
respect to the portion of the cumulative undistributed earnings of foreign subsidiaries and joint ventures that the Company determined
were not essentially permanent in duration.</p>

<p style="margin: 0pt 0; font-size: 10pt">As of August 31, 2020, the Company had foreign tax credit carryforwards of approximately
$5,790,500, which will begin to expire if not utilized prior to August 31, 2021. In addition, the Company had federal and state
tax credit carryforwards of $3,312,400 as of August 31, 2020 which began to expire in fiscal 2021.&nbsp; These federal and state
tax credit carryforwards consist primarily of federal and Minnesota research and development credit carryforwards. The Company
also has a deferred tax asset of $1,260,600 for federal and state net operating loss carryforwards as of August 31, 2020. The federal
net operating loss carryforward has an indefinite carryforward period. The Company has a deferred tax asset of $251,200 for foreign
net operating loss carryforwards, $229,200 of which has an indefinite carryforward period.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company records a tax valuation allowance to reduce deferred tax assets to the amount

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As of August 31, 2020, the Company determined based on all available evidence, including
historical data and projections of future results, that it is more likely than not that its domestic deferred tax assets, including
its foreign tax credit carryforward and federal and Minnesota research and development credit carryforwards will not be realized.
The Company determined that its domestic deferred tax assets, including its federal and state net operating loss carryforwards,
foreign tax credit carryforwards, and federal and Minnesota research and development credit carryforwards will not be realized
due to the absence of objectively verifiable sources of taxable income. On the basis of this evaluation, the Company has recorded
a valuation allowance of $11,561,700 as August 31, 2020 to recognize only the portion of the deferred tax assets that is more likely
than not to be realized. The net deferred tax asset as of August 31, 2020 relates entirely to non-US deferred tax assets which
are expected to be realized by offset of deferred tax liability for withholding tax on cumulative undistributed earnings in foreign
subsidiaries and joint ventures that the Company determined were not essentially permanent.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">As of August 31, 2019, the Company determined it was still in a position that a full
valuation allowance was not necessary and recorded a valuation allowance of $5,790,500 with respect to the foreign tax credit carryforwards
and a valuation allowance of $2,973,800 with respect to federal and state tax credit carryforwards that was determined would not
be utilized prior to expiration. The Company determined that its foreign tax credit carryforward would not be realized due to insufficient
foreign source taxable income within the carryforward period and the fact that for ordering purposes the foreign tax credit carryforward
is not allowed to be utilized until after any current year foreign tax credits are utilized. The Company determined that its federal
and Minnesota research and development credit carryforwards would not be realized due to insufficient federal and Minnesota taxable
income within the carryforward period after considering the foreign tax credit utilization. The change in the valuation allowance
totaled $2,797,000 and $133,000 for the years ended August 31, 2020 and 2019, respectively.</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company currently has operating leases for various buildings, equipment and vehicles.
These leases are under non-cancelable operating lease agreements with expiration dates between November 30, 2020 and June 30, 2024.
The Company has the option to extend certain leases to five or ten-year term(s) and has the right of first refusal on any sale.</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company records lease liabilities within current liabilities or long-term liabilities
based upon the length of time associated with the lease payments. The Company records its long-term operating leases as right-of-use
assets. Upon initial adoption, using the modified retrospective transition approach, no leases with terms less than 12 months have
been capitalized to the consolidated balance sheet consistent with ASC 842. Instead, these leases are recognized in the consolidated
statement of operations on a straight-line expense throughout the lives of the leases. None of the Company&#8217;s leases contain
common area maintenance or security agreements.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company has made certain assumptions and judgments when applying ASC 842, the most
significant of which is that the Company elected the package of practical expedients available for transition that allow the Company
to not reassess whether expired or existing contracts contain leases under the new definition of a lease, lease classification
for expired or existing leases and whether previously capitalized initial direct costs would qualify for capitalization under ASC
842. Additionally, the Company did not elect to use hindsight when considering judgments and estimates such as assessments of lessee
options to extend or terminate a lease or purchase the underlying asset. The Company has no contingent rent agreements.</p>

approved the material terms of an annual bonus plan for the Company&#8217;s executive officers as well as certain officers and
employees for the fiscal year ending August 31, 2021. For fiscal 2021, as in past years, the total amount available under the bonus
plan for all plan participants, including executive officers, is dependent upon the Company&#8217;s earnings before interest, taxes,
and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted
EBITOI). Each plan participant&#8217;s percentage of the overall bonus pool is based upon the number of plan participants, the
individual&#8217;s annual base salary, and the individual&#8217;s position and level of responsibility within the company. In the
case of each of the Company&#8217;s executive officer participants, 75% of the amount of their individual bonus payout will be
determined based upon the Company&#8217;s actual EBITOI for fiscal 2021 compared to a pre-established target EBITOI for fiscal

individual performance objectives. The payment of bonuses under the plan is discretionary, and bonuses may be paid to executive

an amount could be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most
probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount.
The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if
there is a reasonable possibility that material loss may have been incurred. In the opinion of management, as of August 31, 2020,
the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the
Company&#8217;s consolidated results of operations, financial position, or cash flows.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company follows the authoritative guidance on fair value measurements and disclosures
with respect to assets and liabilities that are measured at fair value on both a recurring and non-recurring basis. Under this
guidance, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a
liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes
a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable
inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would
use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable
inputs are inputs that reflect the Company&#8217;s assumptions about the factors market participants would use in valuing the asset
or liability developed based upon the best information available in the circumstances. The categorization of financial assets and
financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value
measurement.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">The hierarchy is broken down into three levels defined as follows:</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0 0pt 0.25in">Level 1 - Inputs are quoted prices in active markets for identical assets
or liabilities.</p>

<p style="font-size: 10pt; text-indent: -45pt; margin: 0pt 0 0pt 63pt">Level 2 - Inputs include quoted prices for similar assets
or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active,
and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.</p>

<p style="font-size: 10pt; margin: 0pt 0 0pt 0.25in">Level 3 - Inputs are unobservable for the asset or liability.</p>

<p style="font-size: 10pt; margin: 0pt 0 0pt 0.25in">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">See the section below titled Valuation Techniques for further discussion of how the Company

in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value
hierarchy. The Company&#8217;s policy is to recognize transfers into and out of levels within the fair value hierarchy at the end

between Level 1, Level 2, or Level 3 during the fiscal years ended August 31, 2020 or August 31, 2019. When a determination is
made to classify an asset or liability within Level 3, the determination is based upon the significance of the unobservable inputs
to the overall fair value measurement.</p>

<p style="margin: 0pt 0; font-size: 10pt">NTIC&#8217;s management is responsible for establishing and maintaining
adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f) for
Northern Technologies International Corporation and its subsidiaries. This system is designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance
with U.S. generally accepted accounting principles.</p>

<p style="margin: 0pt 0; font-size: 10pt">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt">The Company&#8217;s internal control over financial reporting includes
those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles,
and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors
of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use,
or disposition of the Company&#8217;s assets that could have a material effect on the financial statements.</p>

<p style="margin: 0pt 0; font-size: 10pt">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt">Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements, and even when determined to be effective, can only provide reasonable assurance with
respect to financial statement preparation and presentation. In addition, projection of any evaluation of the effectiveness of
internal control over financial reporting to future periods is subject to the risk that controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.</p>

<p style="margin: 0pt 0; font-size: 10pt">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt">Management, with the participation of NTIC&#8217;s President and Chief
Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company&#8217;s internal control over financial
reporting as of August 31, 2020. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission in Internal Control &#8211; Integrated Framework (2013). Based on this assessment, management
concluded that the Company's internal control over financial reporting was effective as of August 31, 2020.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">This report does not include an attestation report of NTIC&#8217;s independent registered
public accounting firm regarding internal control over financial reporting. Management&#8217;s report was not subject to attestation
by NTIC&#8217;s independent registered public accounting firm pursuant to rules of the Securities and Exchange Commission that
permit NTIC to provide only management&#8217;s report in this report.</p>

<p style="font-size: 10pt; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">Changes in Internal Control over Financial Reporting</p>

<p style="font-size: 10pt; font-weight: bold; margin: 0pt 0">&nbsp;</p>

<p style="font-size: 10pt; margin: 0pt 0">There was no change in NTIC&#8217;s internal control over financial reporting that occurred
during the quarter ended August 31, 2020 that has materially affected or is reasonably likely to materially affect NTIC&#8217;s
internal control over financial reporting.</p>

Payment terms for the Company's joint ventures also are determined based on credit risk; however, additional consideration is given to the individual joint venture due to the transportation time associated with ocean delivery of most products and certain other factors. Generally, accounts receivable from the Company's joint ventures unpaid after &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;90&lt;/div&gt; days are considered past due. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; accrue interest on past due balances. The Company periodically reviews amounts due from its joint ventures for collectability and, based on past experience and continuous review of the balances due, determined that an allowance for doubtful accounts related to its joint venture receivables was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; necessary as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;or &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Fees for Services Provided to Joint Ventures &amp;#x2013; &lt;/div&gt;The Company provides services to its joint ventures including consulting, legal, travel, insurance, technical, and marketing services based on licensing or other agreements with its joint ventures. The Company receives fees for the services it provides to its joint ventures. The fees for services received by the Company from its joint ventures are generally based on either a flat fee or a percentage of net sales by the Company's joint ventures depending on local laws and tax regulations. Under the Company's agreements with its joint ventures, amounts are earned when product is shipped from joint venture facilities, at which point a sale is deemed to have occurred and results in obligation for the joint venture to pay the royalty and recognition of the fee by the Company. The Company reviews the financial situation of each of its joint ventures to assist in the likelihood of collections on amounts earned. The Company accounts for these fees on a cash basis if uncertainty exists surrounding the collection of such fees.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</ntic:ReceivablesFromJointVenturesPolicyPolicyTextBlock>

These leases are under non-cancelable operating lease agreements with expiration dates between &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; November 30, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 30, 2024. &lt;/div&gt;The Company has the option to extend certain leases to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt; or &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;ten&lt;/div&gt;-year term(s) and has the right of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; refusal on any sale.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records lease liabilities within current liabilities or long-term liabilities based upon the length of time associated with the lease payments. The Company records its long-term operating leases as right-of-use assets. Upon initial adoption, using the modified retrospective transition approach, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; leases with terms less than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;12&lt;/div&gt; months have been capitalized to the consolidated balance sheet consistent with ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;842.&lt;/div&gt; Instead, these leases are recognized in the consolidated statement of operations on a straight-line expense throughout the lives of the leases. &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;None&lt;/div&gt; of the Company's leases contain common area maintenance or security agreements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company has made certain assumptions and judgments when applying ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;842,&lt;/div&gt; the most significant of which is that the Company elected the package of practical expedients available for transition that allow the Company to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; reassess whether expired or existing contracts contain leases under the new definition of a lease, lease classification for expired or existing leases and whether previously capitalized initial direct costs would qualify for capitalization under ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;842.&lt;/div&gt; Additionally, the Company did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; elect to use hindsight when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset. The Company has &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; contingent rent agreements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Present Value of Leases&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div&gt; &lt;table style="border-collapse: collapse; min-width: 700px;" cellspacing="0" cellpadding="0" align="center"&gt;    &lt;tr style="vertical-align: bottom"&gt;  &lt;td style="font-size: 10pt; border-bottom: Black 1pt solid"&gt;(in thousands):&lt;/td&gt;  &lt;td style="font-size: 10pt; font-weight: bold; padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td colspan="3" style="font-size: 10pt; font-weight: bold; text-align: center; border-bottom: Black 1pt solid"&gt;August 31, 2020&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt;  &lt;td style="width: 84%; font-size: 10pt; text-align: left"&gt;Right-of-use assets, net&lt;/td&gt;  &lt;td style="width: 1%; font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="width: 1%; font-size: 10pt; text-align: left"&gt;$&lt;/td&gt;  &lt;td style="width: 13%; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;658,788&lt;/div&gt;&lt;/td&gt;  &lt;td style="width: 1%; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom; background-color: White"&gt;  &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: right"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;Current portion of lease liability&lt;/td&gt;  &lt;td style="font-size: 10pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;386,345&lt;/div&gt;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom; background-color: White"&gt;  &lt;td style="font-size: 10pt; text-align: left; padding-bottom: 1pt"&gt;Lease liability, less current portion&lt;/td&gt;  &lt;td style="font-size: 10pt; padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;272,443&lt;/div&gt;&lt;/td&gt;  &lt;td style="border-bottom: Black 1pt solid; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt;  &lt;td style="font-size: 10pt; text-align: left; padding-bottom: 2.5pt; padding-left: 20pt"&gt;Total lease liability&lt;/td&gt;  &lt;td style="font-size: 10pt; padding-bottom: 2.5pt"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: left"&gt;$&lt;/td&gt;  &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;658,788&lt;/div&gt;&lt;/td&gt;  &lt;td style="border-bottom: Black 2.5pt double; font-size: 10pt; text-align: left"&gt;&amp;nbsp;&lt;/td&gt;  &lt;/tr&gt;    &lt;/table&gt; &lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;the weighted-average remaining lease term was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2.02&lt;/div&gt; years. The Company's lease agreements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; provide a readily determinable implicit rate nor is it available to the Company from its lessors. Instead, as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;the Company estimates the weighted-average discount rate for its operating leases to be &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2.31%&lt;/div&gt; to present value based on the incremental borrowing rate.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;

font-style: italic; font: inherit;"&gt; August 31, 2021. &lt;/div&gt;For fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021,&lt;/div&gt; as in past years, the total amount available under the bonus plan for all plan participants, including executive officers, is dependent upon the Company's earnings before interest, taxes, and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted EBITOI). Each plan participant's percentage of the overall bonus pool is based upon the number of plan participants, the individual's annual base salary, and the individual's position and level of responsibility within the company. In the case of each of the Company's executive officer participants, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;75%&lt;/div&gt; of the amount of their individual bonus payout will be determined based upon the Company's actual EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021&lt;/div&gt; compared to a pre-established target EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021,&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;25%&lt;/div&gt; of the payout will be determined based upon such executive officer's achievement of certain pre-established individual performance objectives. The payment of bonuses under the plan is discretionary, and bonuses &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;be paid to executive officer participants in both cash and shares of NTIC common stock, the exact amount and percentages of which were determined by the Company's Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company's consolidated financial statements for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019, &lt;/div&gt;the Compensation Committee of the Board of Directors of the Company approved the material terms of an annual bonus plan for the Company's executive officers as well as certain officers and employees for the fiscal year ending &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020. &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,300,000&lt;/div&gt; was recognized for bonuses for the fiscal year ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$800,000&lt;/div&gt; of the bonus is comprised of stock options granted to management on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2019 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$500,000&lt;/div&gt; will be paid out in cash and profit sharing subsequent to year end. This is compared to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$2,000,000&lt;/div&gt; recognized for bonuses for the fiscal year ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019, &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$800,000&lt;/div&gt; of the bonus comprised of stock options granted to management on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2018 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,200,000&lt;/div&gt; was paid out in cash and profit sharing subsequent to year end.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Concentrations &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Five joint ventures (consisting of the Company's joint ventures in the United States, Indonesia, Philippines, Russia and India) accounted for &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;88.2%&lt;/div&gt; of the Company's trade joint venture receivables as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt; joint ventures (consisting of the Company's joint ventures in South Korea, Thailand, France, Germany and India) accounted for &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;69.6%&lt;/div&gt; of the Company's trade joint venture receivables as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Legal Matters &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 23, 2015, &lt;/div&gt;NTIC and NTI Asean LLC, a majority-owned subsidiary of NTIC, filed a lawsuit in Tianjin &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1&lt;/div&gt; Intermediate People's Court against &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt; individuals, Tao Meng and Xu Hui, related to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to NTIC's former joint venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd. The lawsuit alleges, among other things, that Mr. Tao Meng and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust. At this point, the Company is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; able to reasonably estimate the amount of any recovery to NTI Asean, if any.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;From time to time, the Company is subject to various other claims and legal actions in the ordinary course of its business. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements, and judgments, where the Company has assessed that a loss is probable, and an amount could be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; probable or the amount is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; estimable, or both, if there is a reasonable possibility that material loss &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;have been incurred. In the opinion of management, as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;the amount of liability, if any, with respect to these matters, individually or in the aggregate, will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; materially affect the Company's consolidated results of operations, financial position, or cash flows.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

Upon adoption of the new leasing standards, the Company recognized a lease liability and related right-of-use asset on its consolidated balance sheet of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$600,000&lt;/div&gt;&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;New Accounting Pronouncements &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;Not&lt;/div&gt; Yet Adopted&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 2016, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;13,&lt;/div&gt; Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; November 2018, &lt;/div&gt;issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; and in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; April 2019, &lt;/div&gt;issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;04&lt;/div&gt; and in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; May 2019, &lt;/div&gt;issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;05,&lt;/div&gt; and in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; November 2019, &lt;/div&gt;issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;11,&lt;/div&gt; which amended the standard. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures. This ASU is effective for fiscal years beginning after &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; December 15, 2022, &lt;/div&gt;including interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; reporting period in which the guidance is adopted. The Company is still evaluating the impact of this ASU.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Although there are several other new accounting pronouncements issued or proposed by the FASB, which the Company has adopted or will adopt, as applicable, the Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; believe any of these accounting pronouncements has had or will have a material impact on the Company's consolidated financial position or operating results.&lt;/div&gt;&lt;/div&gt;</us-gaap:DescriptionOfNewAccountingPronouncementsNotYetAdopted>

The &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019&lt;/div&gt; Plan replaced the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2007&lt;/div&gt; Plan with respect to future grants; and, therefore, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; further awards &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;be made under the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2007&lt;/div&gt; Plan.

As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;84,693&lt;/div&gt; shares of common stock remained available for sale under the ESPP.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The fair value of option grants is determined at the date of grant using the Black-Scholes option pricing model with the assumptions listed below.&amp;nbsp; The volatility factor used in the Black-Scholes option pricing model is based on historical stock price fluctuations, and the risk-free interest rate is based on U.S. treasury rates appropriate for the expected term. Dividend yield and expected volatility are estimated using historical amounts that are anticipated to be consistent with current values. Expected life of the option is based on the life of the option agreements. Based on these valuations, the Company recognized compensation expense of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,337,774&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,431,925&lt;/div&gt; during fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; and fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019,&lt;/div&gt; respectively, related to the options that vested during such time.

Under the equity method, investments are initially recorded at cost and are adjusted for dividends, distributed and undistributed earnings and losses, changes in foreign currency exchange rates, and additional investments. In the event the Company's share of a joint venture's cumulative losses exceeds the Company's investment balance, the balance is reported at &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;zero&lt;/div&gt; value until proportionate income exceeds the losses. The Company assesses its joint ventures for impairment on an annual basis as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31 &lt;/div&gt;of each year as part of its fiscal year end analysis. In addition to the annual review for impairment, the Company reviews the operating results of each joint venture on a quarterly basis in comparison to its historical operating results and its accrual of fees for services provided to joint ventures. If the operating results of a joint venture do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; meet financial performance expectations, an additional evaluation is performed on the joint venture. The Company's evaluation of its investments in joint ventures requires the Company to make assumptions about future cash flows of its joint ventures. These assumptions require significant judgment, and actual results &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;differ from assumed or estimated amounts. All investments in joint ventures had positive equity as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019.&lt;/div&gt; The Company considers any of its joint ventures to be significant and discloses entity specific financial information if the joint venture's income or assets make up more than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;20%&lt;/div&gt; of the Company's total assets or income.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 62; Value: 1 --&gt; &lt;!-- Field: /Page --&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company classifies distributions received from its joint ventures based on the nature of the distributions, generally, in operating activities on the consolidated statements of cash flows.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;If the Company is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; longer able to exercise significant influence over operating and financial policy of a joint venture previously accounted for under the equity method, it maintains the investment at the carrying value as of the date that significant influence &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; longer exists and discontinues accruing the proportionate earnings or losses of the investment.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. The Company employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, credit quality, the duration and extent to which the fair value is less than cost, and for equity securities, the Company's intent and ability to hold, or plans to sell, the investment. The Company also considers specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis in the investment is established.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:EquityMethodInvestmentsPolicy>

Under this guidance, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The hierarchy is broken down into &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; levels defined as follows:&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;Level &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1&lt;/div&gt; - Inputs are quoted prices in active markets for identical assets or liabilities.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: -45pt; margin: 0pt 0 0pt 63pt"&gt;Level &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2&lt;/div&gt; - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;Level &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;3&lt;/div&gt; - Inputs are unobservable for the asset or liability.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;See the section below titled Valuation Techniques for further discussion of how the Company determines fair value for investments.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Assets and liabilities that are measured at fair value on a recurring basis primarily relate to marketable equity securities.

The Company determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If the sum of the expected undiscounted future net cash flows is less than the carrying value, the Company evaluates whether an impairment loss should be recognized. An impairment loss is measured by comparing the amount by which the carrying value exceeds the fair value of the asset. When evaluating assets for impairment, the Company groups long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock>

The Company has a deferred tax asset of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$251,200&lt;/div&gt; for foreign net operating loss carryforwards, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$229,200&lt;/div&gt; of which has an indefinite carryforward period.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records a tax valuation allowance to reduce deferred tax assets to the amount expected to be realized when it is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; that some portion or all of its deferred tax assets will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020, &lt;/div&gt;the Company determined based on all available evidence, including historical data and projections of future results, that it is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; that its domestic deferred tax assets, including its foreign tax credit carryforward and federal and Minnesota research and development credit carryforwards will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized. The Company determined that its domestic deferred tax assets, including its federal and state net operating loss carryforwards, foreign tax credit carryforwards, and federal and Minnesota research and development credit carryforwards will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized due to the absence of objectively verifiable sources of taxable income. On the basis of this evaluation, the Company has recorded a valuation allowance of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$11,561,700&lt;/div&gt; as &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;to recognize only the portion of the deferred tax assets that is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; to be realized. The net deferred tax asset as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;relates entirely to non-US deferred tax assets which are expected to be realized by offset of deferred tax liability for withholding tax on cumulative undistributed earnings in foreign subsidiaries and joint ventures that the Company determined were &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; essentially permanent.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019, &lt;/div&gt;the Company determined it was still in a position that a full valuation allowance was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; necessary and recorded a valuation allowance of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$5,790,500&lt;/div&gt; with respect to the foreign tax credit carryforwards and a valuation allowance of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$2,973,800&lt;/div&gt; with respect to federal and state tax credit carryforwards that was determined would &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be utilized prior to expiration. The Company determined that its foreign tax credit carryforward would &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized due to insufficient foreign source taxable income within the carryforward period and the fact that for ordering purposes the foreign tax credit carryforward is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; allowed to be utilized until after any current year foreign tax credits are utilized. The Company determined that its federal and Minnesota research and development credit carryforwards would &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized due to insufficient federal and Minnesota taxable income within the carryforward period after considering the foreign tax credit utilization. The change in the valuation allowance totaled &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$2,797,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$133,000&lt;/div&gt; for the years ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019,&lt;/div&gt;

Deferred income tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in operations in the period that includes the enactment date.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records net deferred tax assets to the extent the Company believes these assets will more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records uncertain tax positions on the basis of a &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt;-step process whereby the Company determines whether it is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; that the tax positions will be sustained based on the technical merits of the position and those tax positions that meet the more-likely-than-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; recognition threshold.

The Company's primary business is corrosion prevention marketed mainly under the ZERUST&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;&amp;reg;&lt;/div&gt; brand. The Company has been selling its proprietary ZERUST&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;&amp;reg;&lt;/div&gt; rust and corrosion inhibiting products and services to the automotive, electronics, electrical, mechanical, military, and retail consumer markets for over &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;40&lt;/div&gt; years and, more recently, has targeted and expanded into the oil and gas industry. The Company also sells a portfolio of bio-based and certified compostable (fully biodegradable) polymer resin compounds and finished products under the Natur-Tec&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;&amp;reg;&lt;/div&gt; brand. These products are intended to reduce the Company's customers' carbon footprint and provide environmentally sound disposal options. The Company's &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt; operating segments are ZERUST and Natur-Tec.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company participates, either directly or indirectly, in &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; active joint venture arrangements in North America, Europe, and Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned. While most of the Company's joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also sell the Company's Natur-Tec&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;&amp;reg;&lt;/div&gt; resin compounds and finished products. The profits of joint ventures are shared by the respective joint venture owners in accordance with their respective ownership percentages. The Company typically owns &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;50%&lt;/div&gt; or less of its joint venture entities and does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; control the decisions of these entities, including dividend declaration or amount in any given year.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Impact of COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; Pandemic &lt;/div&gt;&amp;#x2013; In &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; March 2020, &lt;/div&gt;the World Health Organization declared the novel coronavirus (COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt;) outbreak a global pandemic. As a result of the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic and related government mandated restrictions on the Company's business as well as the businesses of its joint ventures, customers and suppliers, disruption to the Company's business and the manufacture and sale of its products and services has occurred and is expected to continue into fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Principles of Consolidation&lt;/div&gt; &amp;#x2013; NTIC evaluates its voting and variable interests in entities on a qualitative and quantitative basis. NTIC consolidates entities in which it concludes it has the power to direct the activities that most significantly impact an entity's economic success and has the obligation to absorb losses or the right to receive benefits that could be significant to the entity. The consolidated financial statements include the accounts of Northern Technologies International Corporation, its wholly-owned subsidiaries, Northern Technologies Holding Company, LLC, NTIC (Shanghai) Co., Ltd. (NTIC China), ZERUST-EXCOR MEXICO, S. de R.L. de C.V (Zerust Mexico), NTIC Europe GmbH (NTI Europe), NTIC's majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India), NTIC's majority-owned subsidiary in Brazil, Zerust Preven&amp;ccedil;&amp;atilde;o de Corros&amp;atilde;o S.A.

Ltd (Zerust Vietnam). NTIC's consolidated financial statements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; include the accounts of any of its joint ventures.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Non-Controlling Interests&lt;/div&gt; &amp;#x2013; The Company owns &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;75%&lt;/div&gt; of Natur-Tec India, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;75%&lt;/div&gt; of Natur Tec Lanka, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;85%&lt;/div&gt; of Zerust Brazil, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;60%&lt;/div&gt; of NTI Asean, &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;60%&lt;/div&gt; of Zerust Singapore Pte Ltd, and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;60%&lt;/div&gt; of Zerust Vietnam Co. Ltd.&amp;nbsp; The remaining ownership of the consolidated entities are accounted for as non-controlling interests and reported as part of equity in the consolidated financial statements. The Company allocates gains and losses to the non-controlling interest even when such allocation results in a deficit balance, reducing the losses attributed to the controlling interest. Changes in ownership interests are treated as equity transactions if the Company maintains control.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Net Sales &lt;/div&gt;&amp;#x2013; The Company includes net sales to its joint ventures and net sales to unaffiliated customers as separate line items on its consolidated statements of operations.

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2018, &lt;/div&gt;the Company adopted ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; for all customer contracts using the modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606,&lt;/div&gt; the Company performs the following &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt; steps: (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1&lt;/div&gt;) identify the contracts with a customer; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2&lt;/div&gt;) identify the performance obligations in the contract; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;3&lt;/div&gt;) determine the transaction price; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;4&lt;/div&gt;) allocate the transaction price to the performance obligations in the contract; and (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;5&lt;/div&gt;) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt;-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The adoption of ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; impact the previously reported financial statements in any prior period or result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; impact the Company's revenue recognition process. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company's services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; contain any significant financing component for its customers. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer arrangements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; generate contract assets or liabilities.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Changes to the Company's significant accounting policies as a result of adopting ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; are discussed below.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Revenue Recognition&lt;/div&gt; &amp;#x2013; Revenue is measured based on consideration specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components. Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Individually promised goods and services in a contract are considered a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; incur significant upfront costs to obtain a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with the related recognition of revenue.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company excludes government assessed and imposed taxes on revenue generating transactions that are invoiced to customers from revenue. The Company includes freight billed to customers in revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The timing of revenue recognition, billing, and cash collections results in accounts receivable on the consolidated balance sheet.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Performance Obligations&lt;/div&gt; - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract's transaction price is allocated to each distinct performance obligation in proportion to its standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. The Company's various performance obligations and the timing or method of revenue recognition are discussed below. The Company's technical&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;service consultants work directly with the end users of NTIC's ZERUST&amp;reg; rust and corrosion inhibiting products to&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;analyze their specific needs and develop systems to meet their performance requirements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 60; Value: 1 --&gt;  &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company sells its products to both distributors and end-users. Each unit of product delivered under a customer order represents a distinct and separate performance obligation, as the customer can benefit from each unit on its own or with other resources that are readily available to the customer, and each unit of product is separately identifiable from other products in the arrangement.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The transaction price for the Company's products is the invoiced amount. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone selling price; therefore, the Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; need to allocate proceeds on a relative standalone selling price allocation between performance obligations. The Company applies the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;50&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;14&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; disclose information about remaining performance obligations that have original expected durations of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less. There are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; material obligations that extend beyond &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Revenue is recognized when transfer of control occurs, as defined by the terms in the customer agreement. The Company immediately recognizes incidental items that are immaterial in the context of the contract. The Company has applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;16A&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; assess if immaterial items are promised goods or services. The Company has also applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;32&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;18&lt;/div&gt; regarding the adjustment of the promised amount of consideration for the effects of a significant financing component when the customer pays for that good or service within &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less, as the Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have any significant financing components in its customer arrangements since payment is received at or shortly after the point of sale, generally &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;thirty&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;ninety&lt;/div&gt; days.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company estimates returns based on an analysis of historical experience if the right to return products is granted to its customers. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; record a return asset, as non-conforming products are generally &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; returned. The Company's return policy does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; vary by geography. The customer has &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; rotation or price protection rights, and the Company is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; under a warranty obligation.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Sales Commissions&lt;/div&gt; &amp;#x2013; Sales commissions paid to sales representatives are eligible for capitalization, as they are incremental costs that would &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have been incurred without entering into a specific sales arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical expedient provided by ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;340&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;40&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;4&lt;/div&gt; and recognize the incremental costs of obtaining contracts as an expense when incurred, as the amortization period of the assets that would have otherwise been recognized is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less. The Company records these costs as a selling expense.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Product Warranty&lt;/div&gt; &amp;#x2013; The Company offers warranties on various products and services. These warranties are assurance type warranties that are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; sold on a standalone basis; therefore, they are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; considered distinct performance obligations. The Company estimates the costs that &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;be incurred under its warranties and records a liability in the amount of such costs at the time the revenue is recognized for the product sale.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;International Revenue&lt;/div&gt; &amp;#x2013; The Company markets its products to numerous countries in North America, Europe, Latin America, Asia, and other parts of the world. See Note &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;11,&lt;/div&gt; Segment and Geographical Information, for information regarding revenue disaggregation by geography.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Trade Receivables&lt;/div&gt; &amp;#x2013; Payment terms for the Company's unaffiliated customers are determined based on credit risk and vary by customer. The Company typically offers standard payment terms to unaffiliated customers of net &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;30&lt;/div&gt; days. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; accrue interest on past due accounts receivable. The Company reviews the credit histories of its customers before extending unsecured credit. The Company presents accounts and notes receivable net of an allowance for doubtful accounts. Each quarter, the Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. In doing so, the Company evaluates the age of its receivables, past collection history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on this evaluation, the Company establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well as an estimate of uncollectible receivables &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; specifically known. The Company believes that an analysis of historical trends and its current knowledge of potential collection problems provide the Company with sufficient information to establish a reasonable estimate for an allowance for doubtful accounts. In the event the Company determines that a smaller or larger uncollectible accounts reserve is appropriate, the Company records a credit or charge to selling expense in the period that it made such determination. Accounts receivable have been reduced by an allowance for uncollectible accounts of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$90,000&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$65,000&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019. &lt;/div&gt;Accounts are considered past due based on terms agreed upon between the Company and the customer. Accounts receivable are written-off only after all collection attempts have failed and are based on individual credit evaluation and specific circumstances of the customer.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 61; Value: 1 --&gt;    &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Trade Receivables from Joint Ventures &lt;/div&gt;&amp;#x2013; Trade receivables from joint ventures arise from sales of products the Company makes to its joint ventures. Payment terms for the Company's joint ventures also are determined based on credit risk; however, additional consideration is given to the individual joint venture due to the transportation time associated with ocean delivery of most products and certain other factors. Generally, accounts receivable from the Company's joint ventures unpaid after &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;90&lt;/div&gt; days are considered past due. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; accrue interest on past due balances. The Company periodically reviews amounts due from its joint ventures for collectability and, based on past experience and continuous review of the balances due, determined that an allowance for doubtful accounts related to its joint venture receivables was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; necessary as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;or &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Fees for Services Provided to Joint Ventures &amp;#x2013; &lt;/div&gt;The Company provides services to its joint ventures including consulting, legal, travel, insurance, technical, and marketing services based on licensing or other agreements with its joint ventures. The Company receives fees for the services it provides to its joint ventures. The fees for services received by the Company from its joint ventures are generally based on either a flat fee or a percentage of net sales by the Company's joint ventures depending on local laws and tax regulations. Under the Company's agreements with its joint ventures, amounts are earned when product is shipped from joint venture facilities, at which point a sale is deemed to have occurred and results in obligation for the joint venture to pay the royalty and recognition of the fee by the Company. The Company reviews the financial situation of each of its joint ventures to assist in the likelihood of collections on amounts earned. The Company accounts for these fees on a cash basis if uncertainty exists surrounding the collection of such fees.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Cash and Cash Equivalents&lt;/div&gt; &amp;#x2013; The Company includes as cash and cash equivalents highly liquid, short-term investments with maturity of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; months or less when purchased, which are readily convertible into known amounts of cash.

Depreciation is computed using the straight-line method based on the estimated service lives of the various assets as follows:&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div&gt; &lt;table style="border-collapse: collapse; min-width: 700px;" cellspacing="0" cellpadding="0"&gt;    &lt;tr style="vertical-align: bottom"&gt;  &lt;td style="width: 25%"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="width: 25%; font-size: 10pt; text-align: left; padding-left: 0pt"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;Buildings and improvements&lt;/div&gt;&lt;/td&gt;  &lt;td style="width: 4%"&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="width: 46%; font-size: 10pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;5-30 years&lt;/div&gt;&lt;/td&gt;  &lt;/tr&gt;  &lt;tr style="vertical-align: bottom"&gt;  &lt;td&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left; padding-left: 0pt"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;Machinery and equipment&lt;/div&gt;&lt;/td&gt;  &lt;td&gt;&amp;nbsp;&lt;/td&gt;  &lt;td style="font-size: 10pt; text-align: left"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;3-10 years&lt;/div&gt;&lt;/td&gt;  &lt;/tr&gt;    &lt;/table&gt; &lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Patents and Trademarks&lt;/div&gt; &amp;#x2013; Patents and trademarks, including acquisition costs, are stated at cost, less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful lives of the respective assets. Upon retirement, the cost of assets disposed and the related accumulated amortization are removed from the accounts, and any resulting gain or loss is credited or charged to operations.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Investments in Joint Ventures&lt;/div&gt; &amp;#x2013; Investments in the Company's joint ventures are accounted for using the equity method. Under the equity method, investments are initially recorded at cost and are adjusted for dividends, distributed and undistributed earnings and losses, changes in foreign currency exchange rates, and additional investments. In the event the Company's share of a joint venture's cumulative losses exceeds the Company's investment balance, the balance is reported at &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;zero&lt;/div&gt; value until proportionate income exceeds the losses. The Company assesses its joint ventures for impairment on an annual basis as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31 &lt;/div&gt;of each year as part of its fiscal year end analysis. In addition to the annual review for impairment, the Company reviews the operating results of each joint venture on a quarterly basis in comparison to its historical operating results and its accrual of fees for services provided to joint ventures. If the operating results of a joint venture do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; meet financial performance expectations, an additional evaluation is performed on the joint venture. The Company's evaluation of its investments in joint ventures requires the Company to make assumptions about future cash flows of its joint ventures. These assumptions require significant judgment, and actual results &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;differ from assumed or estimated amounts. All investments in joint ventures had positive equity as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2019.&lt;/div&gt; The Company considers any of its joint ventures to be significant and discloses entity specific financial information if the joint venture's income or assets make up more than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;20%&lt;/div&gt; of the Company's total assets or income.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 62; Value: 1 --&gt;  &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company classifies distributions received from its joint ventures based on the nature of the distributions, generally, in operating activities on the consolidated statements of cash flows.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;If the Company is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; longer able to exercise significant influence over operating and financial policy of a joint venture previously accounted for under the equity method, it maintains the investment at the carrying value as of the date that significant influence &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; longer exists and discontinues accruing the proportionate earnings or losses of the investment.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. The Company employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, credit quality, the duration and extent to which the fair value is less than cost, and for equity securities, the Company's intent and ability to hold, or plans to sell, the investment. The Company also considers specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis in the investment is established.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Recoverability of Long-Lived Assets&lt;/div&gt; &amp;#x2013; The Company reviews its long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be recoverable. The Company determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If the sum of the expected undiscounted future net cash flows is less than the carrying value, the Company evaluates whether an impairment loss should be recognized. An impairment loss is measured by comparing the amount by which the carrying value exceeds the fair value of the asset. When evaluating assets for impairment, the Company groups long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Income Taxes &lt;/div&gt;&amp;#x2013; The Company utilizes the asset and liability method of accounting for income taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Deferred income tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in operations in the period that includes the enactment date.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records net deferred tax assets to the extent the Company believes these assets will more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company records uncertain tax positions on the basis of a &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt;-step process whereby the Company determines whether it is more likely than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; that the tax positions will be sustained based on the technical merits of the position and those tax positions that meet the more-likely-than-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; recognition threshold. The Company recognizes the largest amount of tax benefit that is greater than &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;50&lt;/div&gt; percent likely to be realized upon ultimate settlement with the related tax authority.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Foreign Currency Translation (Accumulated Other Comprehensive Income (Loss)) &lt;/div&gt;&amp;#x2013; The functional currency of NTIC China, Zerust Brazil, Natur-Tec India, Natur Tec Lanka, Zerust Mexico, Zerust Singapore, Zerust Vietnam, NTI Europe, and each unconsolidated international joint venture is the applicable local currency. The translation of the applicable foreign currencies into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average monthly exchange rate. Translation gains or losses are reported as an element of other comprehensive income (loss).&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 63; Value: 1 --&gt;  &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company (excluding NTIC China, Zerust Brazil, Natur-Tec India, Natur Tec Lanka, Zerust Singapore, Zerust Vietnam, NTI Asean, Zerust Mexico, NTI Europe, and NTIC's joint ventures) conducts all foreign transactions based on the U.S. dollar. Since investments in joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates are reflected as a foreign currency translation adjustment and do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; change the equity in income from joint ventures reflected in the Company's consolidated statements of operations.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Fair Value of Financial Instruments&lt;/div&gt; &amp;#x2013; The carrying value of cash and cash equivalents, available for sale securities, short-term accounts and notes receivable, notes payable, trade accounts payables, and other accrued expenses approximate fair value because of the short maturity of those instruments.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Shipping and Handling&lt;/div&gt; &amp;#x2013; The Company records all amounts billed to customers in a sales transaction related to shipping and handling as sales.

That cost is measured based on the fair value of the equity or liability instruments issued. The Company measures the cost of employee services received in exchange for stock options and other stock-based awards based on the grant-date fair value of the award and recognizes the cost over the period the employee is required to provide services for the award (generally the vesting term).&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Subsequent Events&lt;/div&gt; &amp;#x2013; The Company has evaluated events occurring after the date of the consolidated financial statements for events requiring disclosure in the consolidated financial statements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Use of Estimates&lt;/div&gt; &amp;#x2013; The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.

The Company typically offers standard payment terms to unaffiliated customers of net &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;30&lt;/div&gt; days. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; accrue interest on past due accounts receivable. The Company reviews the credit histories of its customers before extending unsecured credit. The Company presents accounts and notes receivable net of an allowance for doubtful accounts. Each quarter, the Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. In doing so, the Company evaluates the age of its receivables, past collection history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on this evaluation, the Company establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well as an estimate of uncollectible receivables &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; specifically known. The Company believes that an analysis of historical trends and its current knowledge of potential collection problems provide the Company with sufficient information to establish a reasonable estimate for an allowance for doubtful accounts. In the event the Company determines that a smaller or larger uncollectible accounts reserve is appropriate, the Company records a credit or charge to selling expense in the period that it made such determination. Accounts receivable have been reduced by an allowance for uncollectible accounts of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$90,000&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$65,000&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; August 31, 2019. &lt;/div&gt;Accounts are considered past due based on terms agreed upon between the Company and the customer. Accounts receivable are written-off only after all collection attempts have failed and are based on individual credit evaluation and specific circumstances of the customer.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:ReceivablesPolicyTextBlock>

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2018, &lt;/div&gt;the Company adopted ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; for all customer contracts using the modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606,&lt;/div&gt; the Company performs the following &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt; steps: (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1&lt;/div&gt;) identify the contracts with a customer; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2&lt;/div&gt;) identify the performance obligations in the contract; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;3&lt;/div&gt;) determine the transaction price; (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;4&lt;/div&gt;) allocate the transaction price to the performance obligations in the contract; and (&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;5&lt;/div&gt;) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;five&lt;/div&gt;-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The adoption of ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; impact the previously reported financial statements in any prior period or result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; impact the Company's revenue recognition process. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company's services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; contain any significant financing component for its customers. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer arrangements do &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; generate contract assets or liabilities.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Changes to the Company's significant accounting policies as a result of adopting ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt; are discussed below.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Revenue Recognition&lt;/div&gt; &amp;#x2013; Revenue is measured based on consideration specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components. Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Individually promised goods and services in a contract are considered a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; incur significant upfront costs to obtain a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with the related recognition of revenue.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company excludes government assessed and imposed taxes on revenue generating transactions that are invoiced to customers from revenue. The Company includes freight billed to customers in revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The timing of revenue recognition, billing, and cash collections results in accounts receivable on the consolidated balance sheet.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Performance Obligations&lt;/div&gt; - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract's transaction price is allocated to each distinct performance obligation in proportion to its standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. The Company's various performance obligations and the timing or method of revenue recognition are discussed below. The Company's technical&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;service consultants work directly with the end users of NTIC's ZERUST&amp;reg; rust and corrosion inhibiting products to&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;analyze their specific needs and develop systems to meet their performance requirements.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 60; Value: 1 --&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company sells its products to both distributors and end-users. Each unit of product delivered under a customer order represents a distinct and separate performance obligation, as the customer can benefit from each unit on its own or with other resources that are readily available to the customer, and each unit of product is separately identifiable from other products in the arrangement.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The transaction price for the Company's products is the invoiced amount. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone selling price; therefore, the Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; need to allocate proceeds on a relative standalone selling price allocation between performance obligations. The Company applies the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;50&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;14&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; disclose information about remaining performance obligations that have original expected durations of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less. There are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; material obligations that extend beyond &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Revenue is recognized when transfer of control occurs, as defined by the terms in the customer agreement. The Company immediately recognizes incidental items that are immaterial in the context of the contract. The Company has applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;16A&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; assess if immaterial items are promised goods or services. The Company has also applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;32&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;18&lt;/div&gt; regarding the adjustment of the promised amount of consideration for the effects of a significant financing component when the customer pays for that good or service within &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less, as the Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have any significant financing components in its customer arrangements since payment is received at or shortly after the point of sale, generally &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;thirty&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;ninety&lt;/div&gt; days.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company estimates returns based on an analysis of historical experience if the right to return products is granted to its customers. The Company does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; record a return asset, as non-conforming products are generally &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; returned. The Company's return policy does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; vary by geography. The customer has &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; rotation or price protection rights, and the Company is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; under a warranty obligation.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Sales Commissions&lt;/div&gt; &amp;#x2013; Sales commissions paid to sales representatives are eligible for capitalization, as they are incremental costs that would &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have been incurred without entering into a specific sales arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical expedient provided by ASC &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;340&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;40&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;4&lt;/div&gt; and recognize the incremental costs of obtaining contracts as an expense when incurred, as the amortization period of the assets that would have otherwise been recognized is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt; year or less. The Company records these costs as a selling expense.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Product Warranty&lt;/div&gt; &amp;#x2013; The Company offers warranties on various products and services. These warranties are assurance type warranties that are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; sold on a standalone basis; therefore, they are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; considered distinct performance obligations. The Company estimates the costs that &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; may &lt;/div&gt;be incurred under its warranties and records a liability in the amount of such costs at the time the revenue is recognized for the product sale.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;International Revenue&lt;/div&gt; &amp;#x2013; The Company markets its products to numerous countries in North America, Europe, Latin America, Asia, and other parts of the world. See Note &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;11,&lt;/div&gt; Segment and Geographical Information, for information regarding revenue disaggregation by geography.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:RevenueRecognitionDeferredRevenue>

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">On <div style="display: inline; font-style: italic; font: inherit;"> September 1, 2018, </div>the Company adopted ASC <div style="display: inline; font-style: italic; font: inherit;">606</div> for all customer contracts using the modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC <div style="display: inline; font-style: italic; font: inherit;">606,</div> the Company performs the following <div style="display: inline; font-style: italic; font: inherit;">five</div> steps: (<div style="display: inline; font-style: italic; font: inherit;">1</div>) identify the contracts with a customer; (<div style="display: inline; font-style: italic; font: inherit;">2</div>) identify the performance obligations in the contract; (<div style="display: inline; font-style: italic; font: inherit;">3</div>) determine the transaction price; (<div style="display: inline; font-style: italic; font: inherit;">4</div>) allocate the transaction price to the performance obligations in the contract; and (<div style="display: inline; font-style: italic; font: inherit;">5</div>) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the <div style="display: inline; font-style: italic; font: inherit;">five</div>-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The adoption of ASC <div style="display: inline; font-style: italic; font: inherit;">606</div> did <div style="display: inline; font-style: italic; font: inherit;">not</div> impact the previously reported financial statements in any prior period or result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did <div style="display: inline; font-style: italic; font: inherit;">not</div> impact the Company's revenue recognition process. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company's services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do <div style="display: inline; font-style: italic; font: inherit;">not</div> contain any significant financing component for its customers. The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> recognize revenue related to product warranties, nor does the Company incur significant contract costs.

Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">Individually promised goods and services in a contract are considered a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> incur significant upfront costs to obtain a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with the related recognition of revenue.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The Company excludes government assessed and imposed taxes on revenue generating transactions that are invoiced to customers from revenue.

The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone selling price; therefore, the Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> need to allocate proceeds on a relative standalone selling price allocation between performance obligations.

The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> accrue interest on past due accounts receivable. The Company reviews the credit histories of its customers before extending unsecured credit. The Company presents accounts and notes receivable net of an allowance for doubtful accounts. Each quarter, the Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. In doing so, the Company evaluates the age of its receivables, past collection history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on this evaluation, the Company establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well as an estimate of uncollectible receivables <div style="display: inline; font-style: italic; font: inherit;">not</div> specifically known. The Company believes that an analysis of historical trends and its current knowledge of potential collection problems provide the Company with sufficient information to establish a reasonable estimate for an allowance for doubtful accounts. In the event the Company determines that a smaller or larger uncollectible accounts reserve is appropriate, the Company records a credit or charge to selling expense in the period that it made such determination. Accounts receivable have been reduced by an allowance for uncollectible accounts of <div style="display: inline; font-style: italic; font: inherit;">$90,000</div> as of <div style="display: inline; font-style: italic; font: inherit;"> August 31, 2020 </div>and <div style="display: inline; font-style: italic; font: inherit;">$65,000</div> as of <div style="display: inline; font-style: italic; font: inherit;"> August 31, 2019. </div>Accounts are considered past due based on terms agreed upon between the Company and the customer.

Payment terms for the Company's joint ventures also are determined based on credit risk; however, additional consideration is given to the individual joint venture due to the transportation time associated with ocean delivery of most products and certain other factors. Generally, accounts receivable from the Company's joint ventures unpaid after <div style="display: inline; font-style: italic; font: inherit;">90</div> days are considered past due. The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> accrue interest on past due balances. The Company periodically reviews amounts due from its joint ventures for collectability and, based on past experience and continuous review of the balances due, determined that an allowance for doubtful accounts related to its joint venture receivables was <div style="display: inline; font-style: italic; font: inherit;">not</div> necessary as of <div style="display: inline; font-style: italic; font: inherit;"> August 31, 2020 </div>or <div style="display: inline; font-style: italic; font: inherit;">2019.</div></div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;">Fees for Services Provided to Joint Ventures &#x2013; </div>The Company provides services to its joint ventures including consulting, legal, travel, insurance, technical, and marketing services based on licensing or other agreements with its joint ventures. The Company receives fees for the services it provides to its joint ventures. The fees for services received by the Company from its joint ventures are generally based on either a flat fee or a percentage of net sales by the Company's joint ventures depending on local laws and tax regulations. Under the Company's agreements with its joint ventures, amounts are earned when product is shipped from joint venture facilities, at which point a sale is deemed to have occurred and results in obligation for the joint venture to pay the royalty and recognition of the fee by the Company.

Under the equity method, investments are initially recorded at cost and are adjusted for dividends, distributed and undistributed earnings and losses, changes in foreign currency exchange rates, and additional investments. In the event the Company's share of a joint venture's cumulative losses exceeds the Company's investment balance, the balance is reported at <div style="display: inline; font-style: italic; font: inherit;">zero</div> value until proportionate income exceeds the losses. The Company assesses its joint ventures for impairment on an annual basis as of <div style="display: inline; font-style: italic; font: inherit;"> August 31 </div>of each year as part of its fiscal year end analysis. In addition to the annual review for impairment, the Company reviews the operating results of each joint venture on a quarterly basis in comparison to its historical operating results and its accrual of fees for services provided to joint ventures. If the operating results of a joint venture do <div style="display: inline; font-style: italic; font: inherit;">not</div> meet financial performance expectations, an additional evaluation is performed on the joint venture. The Company's evaluation of its investments in joint ventures requires the Company to make assumptions about future cash flows of its joint ventures. These assumptions require significant judgment, and actual results <div style="display: inline; font-style: italic; font: inherit;"> may </div>differ from assumed or estimated amounts. All investments in joint ventures had positive equity as of <div style="display: inline; font-style: italic; font: inherit;"> August 31, 2020 </div>and <div style="display: inline; font-style: italic; font: inherit;">2019.</div> The Company considers any of its joint ventures to be significant and discloses entity specific financial information if the joint venture's income or assets make up more than <div style="display: inline; font-style: italic; font: inherit;">20%</div> of the Company's total assets or income.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" margin: 0pt 0; font-size: 10pt"></div> <!-- Field: Page; Sequence: 62; Value: 1 -->  <div style=" margin: 0pt 0; font-size: 10pt"></div> <div style=" font-size: 10pt; margin: 0pt 0">The Company classifies distributions received from its joint ventures based on the nature of the distributions, generally, in operating activities on the consolidated statements of cash flows.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">If the Company is <div style="display: inline; font-style: italic; font: inherit;">no</div> longer able to exercise significant influence over operating and financial policy of a joint venture previously accounted for under the equity method, it maintains the investment at the carrying value as of the date that significant influence <div style="display: inline; font-style: italic; font: inherit;">no</div> longer exists and discontinues accruing the proportionate earnings or losses of the investment.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. The Company employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, credit quality, the duration and extent to which the fair value is less than cost, and for equity securities, the Company's intent and ability to hold, or plans to sell, the investment. The Company also considers specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis in the investment is established.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div></div> <div style=" font-size: 10pt; margin: 0pt 0"></div> <div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;"></div></div> <div style="display: inline; font-style: italic; font: inherit;"><div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;"></div></div><div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;">Recoverability of Long-Lived Assets</div> &#x2013; The Company reviews its long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets <div style="display: inline; font-style: italic; font: inherit;"> may </div><div style="display: inline; font-style: italic; font: inherit;">not</div> be recoverable. The Company determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If the sum of the expected undiscounted future net cash flows is less than the carrying value, the Company evaluates whether an impairment loss should be recognized. An impairment loss is measured by comparing the amount by which the carrying value exceeds the fair value of the asset. When evaluating assets for impairment, the Company groups long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div><div style=" font-size: 10pt; margin: 0pt 0"></div></div> <div style=" font-size: 10pt; margin: 0pt 0"></div> <div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;"></div></div> <div style="display: inline; font-style: italic; font: inherit;"><div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;">Income Taxes </div>&#x2013; The Company utilizes the asset and liability method of accounting for income taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Deferred income tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in operations in the period that includes the enactment date.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The Company records net deferred tax assets to the extent the Company believes these assets will more likely than <div style="display: inline; font-style: italic; font: inherit;">not</div> be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The Company records uncertain tax positions on the basis of a <div style="display: inline; font-style: italic; font: inherit;">two</div>-step process whereby the Company determines whether it is more likely than <div style="display: inline; font-style: italic; font: inherit;">not</div> that the tax positions will be sustained based on the technical merits of the position and those tax positions that meet the more-likely-than-<div style="display: inline; font-style: italic; font: inherit;">not</div> recognition threshold.

Under this guidance, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The hierarchy is broken down into <div style="display: inline; font-style: italic; font: inherit;">three</div> levels defined as follows:</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in">Level <div style="display: inline; font-style: italic; font: inherit;">1</div> - Inputs are quoted prices in active markets for identical assets or liabilities.</div> <div style=" font-size: 10pt; text-indent: -45pt; margin: 0pt 0 0pt 63pt">Level <div style="display: inline; font-style: italic; font: inherit;">2</div> - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are <div style="display: inline; font-style: italic; font: inherit;">not</div> active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.</div> <div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in">Level <div style="display: inline; font-style: italic; font: inherit;">3</div> - Inputs are unobservable for the asset or liability.</div> <div style=" font-size: 10pt; margin: 0pt 0 0pt 0.25in">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">See the section below titled Valuation Techniques for further discussion of how the Company determines fair value for investments.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0"><div style="display: inline; font-style: italic;">Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis</div></div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">Assets and liabilities that are measured at fair value on a recurring basis primarily relate to marketable equity securities.

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">On <div style="display: inline; font-style: italic; font: inherit;"> September 1, 2018, </div>the Company adopted ASC <div style="display: inline; font-style: italic; font: inherit;">606</div> for all customer contracts using the modified retrospective method.

The Company only applies the <div style="display: inline; font-style: italic; font: inherit;">five</div>-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The adoption of ASC <div style="display: inline; font-style: italic; font: inherit;">606</div> did <div style="display: inline; font-style: italic; font: inherit;">not</div> impact the previously reported financial statements in any prior period or result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did <div style="display: inline; font-style: italic; font: inherit;">not</div> impact the Company's revenue recognition process. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company's services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do <div style="display: inline; font-style: italic; font: inherit;">not</div> contain any significant financing component for its customers. The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> recognize revenue related to product warranties, nor does the Company incur significant contract costs.

When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does <div style="display: inline; font-style: italic; font: inherit;">not</div> incur significant upfront costs to obtain a contract.

The Company reviews the credit histories of its customers before extending unsecured credit. The Company presents accounts and notes receivable net of an allowance for doubtful accounts. Each quarter, the Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. In doing so, the Company evaluates the age of its receivables, past collection history, current financial conditions of key customers and its joint ventures, and economic conditions. Based on this evaluation, the Company establishes a reserve for specific accounts and notes receivable that it believes are uncollectible, as well as an estimate of uncollectible receivables <div style="display: inline; font-style: italic; font: inherit;">not</div> specifically known. The Company believes that an analysis of historical trends and its current knowledge of potential collection problems provide the Company with sufficient information to establish a reasonable estimate for an allowance for doubtful accounts.

Under the equity method, investments are initially recorded at cost and are adjusted for dividends, distributed and undistributed earnings and losses, changes in foreign currency exchange rates, and additional investments. In the event the Company's share of a joint venture's cumulative losses exceeds the Company's investment balance, the balance is reported at <div style="display: inline; font-style: italic; font: inherit;">zero</div> value until proportionate income exceeds the losses. The Company assesses its joint ventures for impairment on an annual basis as of <div style="display: inline; font-style: italic; font: inherit;"> August 31 </div>of each year as part of its fiscal year end analysis. In addition to the annual review for impairment, the Company reviews the operating results of each joint venture on a quarterly basis in comparison to its historical operating results and its accrual of fees for services provided to joint ventures. If the operating results of a joint venture do <div style="display: inline; font-style: italic; font: inherit;">not</div> meet financial performance expectations, an additional evaluation is performed on the joint venture. The Company's evaluation of its investments in joint ventures requires the Company to make assumptions about future cash flows of its joint ventures. These assumptions require significant judgment, and actual results <div style="display: inline; font-style: italic; font: inherit;"> may </div>differ from assumed or estimated amounts. All investments in joint ventures had positive equity as of <div style="display: inline; font-style: italic; font: inherit;"> August 31, 2020 </div>and <div style="display: inline; font-style: italic; font: inherit;">2019.</div> The Company considers any of its joint ventures to be significant and discloses entity specific financial information if the joint venture's income or assets make up more than <div style="display: inline; font-style: italic; font: inherit;">20%</div> of the Company's total assets or income.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" margin: 0pt 0; font-size: 10pt"></div> <!-- Field: Page; Sequence: 62; Value: 1 --> <!-- Field: /Page --> <div style=" margin: 0pt 0; font-size: 10pt">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">The Company classifies distributions received from its joint ventures based on the nature of the distributions, generally, in operating activities on the consolidated statements of cash flows.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">If the Company is <div style="display: inline; font-style: italic; font: inherit;">no</div> longer able to exercise significant influence over operating and financial policy of a joint venture previously accounted for under the equity method, it maintains the investment at the carrying value as of the date that significant influence <div style="display: inline; font-style: italic; font: inherit;">no</div> longer exists and discontinues accruing the proportionate earnings or losses of the investment.</div> <div style=" font-size: 10pt; margin: 0pt 0">&nbsp;</div> <div style=" font-size: 10pt; margin: 0pt 0">Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. The Company employs a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, credit quality, the duration and extent to which the fair value is less than cost, and for equity securities, the Company's intent and ability to hold, or plans to sell, the investment. The Company also considers specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, and operational and financing cash flow factors. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense), and a new cost basis in the investment is established.</div></div></div><span></span>

The Company determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products.

An impairment loss is measured by comparing the amount by which the carrying value exceeds the fair value of the asset.
