<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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 slowdown.
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 through the fourth quarter of fiscal 2020 and beyond. 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 during the fourth quarter of fiscal 2020 and beyond; however, the precise financial impact and duration
cannot be reasonably estimated at this time.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In response to the impact of the COVID-19 pandemic, and given
the uncertainty of its duration, the Company has taken a number of precautionary measures, including the withdrawal and suspension
of its specific full-year fiscal 2020 guidance and the temporary suspension of its quarterly cash dividend.</p></div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In February 2016, the Financial Accounting Standards Board (FASB)
issued Accounting Standards Update (ASU) No. 2016-02, <i>Leases</i>. The guidance in ASU 2016-02 supersedes the lease recognition
requirements in the Accounting Standards Codification (ASC) Topic 840, <i>Leases</i>. ASU 2016-02 requires an entity to recognize
assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative
disclosures. This standard became effective for the Company on September 1, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The FASB has subsequently issued the following amendments to
ASU 2016-02, which have the same effective date and transition date of September 1, 2019, and which are collectively referred to
as the new leasing standards:</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In February 2018, the FASB issued ASU No. 2018-02, <i>Income
Statement &#8211; Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive
Income</i>, which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects
resulting from the 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 by the Company commencing with first quarter of the Company&#8217;s fiscal year 2020, and it did not have any impact
on its consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In June 2016, the FASB issued ASU No. 2016-13, <i>Measurement
of Credit Losses on Financial Instruments</i>, 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>

loss position of the Company. 71,273 shares were excluded from the computation for the three months ended May 31, 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On August 31, 2019, the Compensation Committee of the Board
of Directors of the Company 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, 2020. For fiscal 2020 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 (EBITOI), 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 2020 compared to a pre-established target
EBITOI for fiscal 2020, and 25% of the payout will be determined based upon such executive officer&#8217;s achievement of certain
pre-established individual performance objectives. The payment of bonuses under the plan is discretionary, and bonuses may be paid
to executive officer participants in both cash and shares of NTIC common stock, with the exact amount and percentages determined
by the Company&#8217;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&#8217;s
consolidated financial statements for fiscal 2020. There was $1,200,000 recognized for management bonuses for the nine months ended
May 31, 2020, compared to $1,450,000 recognized for management bonuses for the nine months ended May 31, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">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 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 May
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></div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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. 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; 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, pet waste collection bags, cutlery, 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: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; 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 slowdown.
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: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">As the events surrounding the COVID-19 pandemic continued to
unfold during the third quarter of fiscal 2020, 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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 quarter 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. During the third quarter 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, during the remainder of fiscal 2020. 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">As a result of the global economic slowdown caused by the COVID-19
pandemic, NTIC began experiencing softened demand. During the third quarter of fiscal 2020, demand significantly decreased, which
had a material adverse effect on NTIC&#8217;s business, operating results and financial condition. NTIC anticipates decreased global
demand for its products and services during the fourth quarter of fiscal 2020 and beyond. 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 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>

consolidated net sales for the three months ended May 31, 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

70.0% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of ZERUST<sup>&#174;</sup> products and services,
which decreased 27.0% and 10.0% to $7,356,781 and $26,322,515, respectively, compared to $10,077,203 and $29,250,772 during the
three and nine months ended May 31, 2019, respectively. These decreases were due to lower sales to existing customers for products
as a result of decreased demand. 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 the nine months ended May 31, 2020 included
$2,012,543 of sales made to customers in the oil and gas industry, compared to $2,225,490 for the nine months ended May 31, 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 the three months ended May 31, 2020 were adversely affected by reduced demand

for existing products as a result of decreased demand. The decreases in net sales of NTIC&#8217;s joint ventures resulted in corresponding
decreases 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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Net Sales</i>. NTIC&#8217;s consolidated net sales decreased
34.6% and 11.1% to $9,744,823 and $37,610,006 during the three and nine months ended May 31, 2020, respectively, compared to the
three and nine months ended May 31, 2019. NTIC&#8217;s consolidated net sales for the three months ended May 31, 2020 were adversely
affected by reduced demand globally as a result of the COVID-19 pandemic. NTIC&#8217;s consolidated net sales to unaffiliated customers
excluding NTIC&#8217;s joint ventures decreased 34.2% and 9.7% to $9,071,072 and $36,105,009 during the three and nine months ended
May 31, 2020, respectively, compared to the same respective periods in fiscal 2019. Net sales to joint ventures decreased 39.4%
and 34.7% to $673,751 and $1,504,997 during the three and nine months ended May 31, 2020, respectively, compared to the same respective
periods in fiscal 2019. These decreases were 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 in the fourth quarter of fiscal 2020 and beyond.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC&#8217;s total ZERUST<sup>&#174;</sup> net sales decreased
during the three months and nine months ended May 31, 2020, compared to the prior fiscal year periods, primarily due to an overall
decreased demand for ZERUST<sup>&#174;</sup> industrial products and services in North America and decreased demand for ZERUST<sup>&#174;</sup>
oil and gas products and services. NTIC&#8217;s sales of ZERUST<sup>&#174;</sup> products and services for the three months ended
May 31, 2020 were adversely affected by reduced demand globally as a result of the COVID-19 pandemic.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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 outbreak in China and will likely have a significant
adverse effect on sales of ZERUST<sup>&#174;</sup> products and services in the fourth quarter of fiscal 2020 and beyond. Although
net sales by NTIC&#8217;s wholly owned NTIC China subsidiary decreased 16.3% to $3.1 million for the three months ended May 31,
2020, compared to $3.7 million for the same period last fiscal year, management believes NTIC China sales are beginning to improve
to close to pre-pandemic levels due primarily to NTIC&#8217;s successful expansion into new non-automotive market segments in China.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">ZERUST<sup>&#174;</sup> oil and gas net sales decreased 51.9%
during the three months ended March 31, 2020 compared to the same period last fiscal year primarily 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During the three and nine months ended May 31, 2020, 24.5% and
30.0% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of Natur-Tec<sup>&#174;</sup> products, which
decreased 50.4% and 13.5% to $2,388,042 and $11,287,491 during the three and nine months ended May 31, 2020, respectively, compared
to the three and nine months ended May 31, 2019. These decreases were 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
in the fourth quarter of fiscal 2020 and beyond.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Cost of Goods Sold</i>. Cost of goods sold decreased 35.9%
and 13.5% for the three and nine months ended May 31, 2020, respectively, compared to the three and nine months ended May 31, 2019.
Cost of goods sold as a percentage of net sales decreased to 66.7% during the three months ended May 31, 2020, compared to 68.1%
during the three months ended May 31, 2019 and 66.4% during the nine months ended May 31, 2020, compared to 68.3% during the nine
months ended May 31, 2019. These decreases were due primarily to a decreased percentage of product sales from Natur-Tec&#174; products
that have lower gross margins than NTIC&#8217;s traditional ZERUST&#174; industrial products.</p>

in income from joint ventures decreased 56.8% and 38.1% to $811,787 and $3,466,581 during the three and nine months ended May 31,
2020, respectively, compared to $1,877,410 and $5,596,788 during the three and nine months ended May 31, 2019, respectively. These
changes were primarily a result of changing profitability of the joint ventures during the respective periods that fluctuate based
on net sales. Of the total equity in income from joint ventures, NTIC had equity in income from joint ventures of $2,246,930 attributable
to EXCOR during the nine months ended May 31, 2020, compared to $4,094,763 during the nine months ended May 31, 2019. NTIC had
equity in income from all other joint ventures of $1,219,651 during the nine months ended May 31, 2020, compared to $1,502,025
during the nine months ended May 31, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Fees for Services Provided to Joint Ventures.</i> NTIC recognized
fee income for services provided to joint ventures of $876,706 and $3,491,244 during the three and nine months ended May 31, 2020,
respectively, compared to $1,433,823 and $4,299,032 during the three and nine months ended May 31, 2019, respectively, representing
decreases of 38.9% and 18.8%, respectively. Fee income for services provided to joint ventures is traditionally a function of the
sales made by NTIC&#8217;s joint ventures. Total net sales of NTIC&#8217;s joint ventures decreased 32.4% and 20.3% to $18,782,233
and $68,531,897 during the three and nine months ended May 31, 2020, respectively, compared to $27,774,112 and $86,003,918 for
the three and nine months ended May 31, 2019, respectively. Net sales of NTIC&#8217;s joint ventures are not included in NTIC&#8217;s
consolidated financial statements. Of the total fee income for services provided to joint ventures, fees of $620,106 were attributable
to EXCOR during the nine months ended May 31, 2020, $643,154 attributable to EXCOR during the nine months ended May 31, 2019. NTIC
anticipates that net sales of its joint ventures may continue to decrease significantly as a result of continued decreased demand
as a result of the COVID-19 pandemic and is expected to have a significant adverse effect on NTIC&#8217;s equity in income from
its joint ventures for the fourth quarter of fiscal 2020 and beyond.</p>

5.0% for the nine months ended May 31, 2020 compared to the same period in fiscal 2019 due primarily to increased operating expenses
associated with ZERUST&#174; sales efforts, consisting primarily of personnel expenses. Selling expenses as a percentage of net

the same respective periods in 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 a $170 thousand charge due to a loss on disposal of certain
fixed assets and patents. As a percentage of net sales, general and administrative expenses increased to 22.7% and 17.6% for the
three and nine months ended May 31, 2020, respectively, from 17.0% and 16.5% for the same respective periods in fiscal 2019. These

research and development expenses increased 4.0% for the nine months ended May 31, 2020 compared to the same period in fiscal 2019

NTIC incurred interest income of $15,881 during the nine months ended May 31, 2020 compared to interest income of $40,666 during
the nine months ended May 31, 2019. These changes were due primarily to volatile changes to the invested cash in a conservative

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>(Loss) Income Before Income Tax Expense</i>. NTIC incurred

during the three and nine months ended May 31, 2019, respectively. Income tax expense was calculated based on management&#8217;s
estimate of NTIC&#8217;s annual effective income tax rate. The quarter-over-quarter increase in the Company&#8217;s effective income
tax rate is primarily due to foreign withholding taxes paid on dividends received from NTIC&#8217;s joint ventures during the quarter.
Dividends received from NTIC&#8217;s joint ventures do not represent a component of income before income tax expense. Therefore,
to the extent dividends received from NTIC&#8217;s joint ventures exceed estimated amounts, foreign withholding taxes paid on such
dividends result in an increase in the effective income tax rate in comparison to prior periods.</p>

to be indefinitely invested outside the United States on the bases of estimates that NTIC&#8217;s future domestic cash generation
will be sufficient to meet future domestic cash needs. As a result, U.S. income and foreign withholding taxes have not been recognized
on the cumulative undistributed earnings of $19,706,983 and $22,178,126 at May 31, 2020 and August 31, 2019, respectively. To the
extent undistributed earnings of NTIC&#8217;s joint ventures are distributed in the future, they are not expected to result in
any material additional income tax liability after the application of foreign tax credits.</p>

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>

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, and any stock repurchases for at least the next 12 months. During the remainder
of fiscal 2020, 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

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. Therefore, NTIC believes there is limited exposure by NTIC&#8217;s joint ventures

an increase in accounts payable and accounts receivable, 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: 10pt Times New Roman, Times, Serif; 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. 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. Key external factors include the availability of primary raw materials and sub-contractor
production lead times. NTIC&#8217;s typical contractual terms 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; 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>

in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to provide reasonable

of 1934, as amended, is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange

a lawsuit in Tianjin No 1 Intermediate People&#8217;s Court against two individuals, Tao Meng and Xu Hui, related to breaches of
duties and contractual commitments owed to NTI Asean under certain agreements related to NTIC&#8217;s former joint venture in China,
Tianjin Zerust Anti-Corrosion Technologies Ltd. (Tianjin Zerust). The lawsuit alleges, among other things, that Mr. Tao Meng and
Mr. Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Although Item 1A is inapplicable to NTIC as a smaller reporting
company, NTIC hereby discloses the following additional risk to NTIC&#8217;s risk factors described in its annual report on Form
10-K for the fiscal year ended August 31, 2019:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><b><i>The outbreak and continuing rapid spread of a novel strain
of the coronavirus (COVID-19) has already adversely impacted and will likely continue to adversely impact NTIC&#8217;s business,
operating results and financial condition.</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">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 many countries abroad. As part of intensifying efforts to contain the spread of COVID-19, a growing number of state, local
and foreign governments have imposed various restrictions on the conduct of business and travel. 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 already adversely impacted and will likely continue to adversely
impact NTIC directly, as well as cause its customers and suppliers to slow or stop production, which will likely significantly
disrupt NTIC&#8217;s sales, production and supply chain. For example, as a result of the COVID-19 outbreak in China in December
2019, NTIC experienced decreased demand for its products and services in China and other places in Asia during the three months
ended February 29, 2020. The operations at NTIC China were suspended on January 18, 2020 and did not resume until February 28,
2020. In addition, NTIC&#8217;s location in India was under mandated governmental shutdown until April 15, 2020. NTIC anticipates
significantly decreased global demand for its products and services during third quarter of fiscal 2020 and beyond. This significantly
decreased demand will likely have a material adverse effect on NTIC&#8217;s business, operating results and financial condition
beginning with third quarter of fiscal 2020. Due to the international reach of COVID-19, NTIC anticipates that its international
joint ventures will also be adversely impacted by the causes listed above, as well as other local issues that may arise, which
will likely have a material adverse effect on NTIC&#8217;s joint venture operations and equity in income from joint ventures in
the third quarter of fiscal 2020 and beyond. 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
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>

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: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 19; Value: 1 --&gt;    &lt;!-- Field: /Page --&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; 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&amp;#x2019;s leases contain common area maintenance or security agreements.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 0in"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Present Value of Long-term Leases&lt;/div&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 0in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div&gt; &lt;table cellpadding="0" cellspacing="0" style="; border-collapse: collapse; font: 10pt Times New Roman, Times, Serif; min-width: 700px;"&gt;  &lt;tr style="vertical-align: bottom"&gt; &lt;td style="border-bottom: Black 1pt solid"&gt;(in thousands):&lt;/td&gt; &lt;td style="font-weight: bold; padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td colspan="3" style="font-weight: bold; text-align: center; border-bottom: Black 1pt solid"&gt;May 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: 87%; text-align: left"&gt;Right-of-use assets, net&lt;/td&gt; &lt;td style="width: 1%"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="width: 1%; text-align: left"&gt;$&lt;/td&gt; &lt;td style="width: 10%; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;451,188&lt;/div&gt;&lt;/td&gt; &lt;td style="width: 1%; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: White"&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="text-align: right"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="text-align: left"&gt;Current portion of lease liability&lt;/td&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;136,714&lt;/div&gt;&lt;/td&gt; &lt;td style="text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: White"&gt; &lt;td style="text-align: left; padding-bottom: 1pt"&gt;Lease liability, less current portion&lt;/td&gt; &lt;td style="padding-bottom: 1pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;314,474&lt;/div&gt;&lt;/td&gt; &lt;td style="border-bottom: Black 1pt solid; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="padding-left: 40pt; text-align: left"&gt;Total lease liability&lt;/td&gt; &lt;td style="padding-bottom: 2.5pt"&gt;&amp;nbsp;&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; text-align: left"&gt;$&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;451,188&lt;/div&gt;&lt;/td&gt; &lt;td style="border-bottom: Black 2.5pt double; text-align: left"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt;  &lt;/table&gt; &lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in"&gt;As of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; May 31, 2020, &lt;/div&gt;the weighted-average remaining lease term was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;1.9&lt;/div&gt; years. The Company&amp;#x2019;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.

&lt;div style=" font: 10pt Times New Roman, Times, Serif; 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&amp;#x2019;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;For fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&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&amp;#x2019;s earnings before interest, taxes and other income (EBITOI), as adjusted to take into account amounts to be paid under the bonus plan and certain other adjustments (Adjusted EBITOI). Each plan participant&amp;#x2019;s percentage of the overall bonus pool is based upon the number of plan participants, the individual&amp;#x2019;s annual base salary and the individual&amp;#x2019;s position and level of responsibility within the Company. In the case of each of the Company&amp;#x2019;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&amp;#x2019;s actual EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; compared to a pre-established target EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&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&amp;#x2019;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, with the exact amount and percentages determined by the Company&amp;#x2019;s Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&amp;#x2019;s consolidated financial statements for fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020.&lt;/div&gt; There was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,200,000&lt;/div&gt; recognized for management bonuses for the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; May 31, 2020, &lt;/div&gt;compared to &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$1,450,000&lt;/div&gt; recognized for management bonuses for the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; May 31, 2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 20; Value: 1 --&gt;    &lt;!-- Field: /Page --&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;Two joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea and Thailand) accounted for &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;56.2%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; May 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&amp;#x2019;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&amp;#x2019;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: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; 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; May 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&amp;#x2019;s consolidated results of operations, financial position, or cash flows.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

be updated and the disclosures required under Topic &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;842&lt;/div&gt; will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt;

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&amp;#x2019;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.

&lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;The Company adopted the new leasing standards on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 1, 2019, &lt;/div&gt;using a modified retrospective transition approach to be applied to leases existing as of, or entered into after, &lt;div style="display: inline;

be updated and the disclosures required under Topic &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;842&lt;/div&gt; will &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt;

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;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Recently Issued Accounting Pronouncements&lt;/div&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; February 2018, &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;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;02,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Income Statement &amp;#x2013; Reporting Comprehensive Income (Topic &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;220&lt;/div&gt;) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income&lt;/div&gt;, which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from the 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 &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;02,&lt;/div&gt; however, does &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; 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 &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;02&lt;/div&gt; was adopted by the Company commencing with &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; quarter of the Company&amp;#x2019;s fiscal year &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020,&lt;/div&gt; and it did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have any impact on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 10; Value: 1 --&gt; &lt;!-- Field: /Page --&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; 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; &lt;div style="display: inline; font-style: italic;"&gt;Measurement of Credit Losses on Financial Instruments&lt;/div&gt;, 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&amp;#x2019;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: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; 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&amp;#x2019;s consolidated financial position or operating results.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

The COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; 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 slowdown. 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&amp;#x2019;s business as well as the businesses of its joint ventures, customers and suppliers, disruption to the Company&amp;#x2019;s business and the manufacture and sale of its products and services has occurred and is expected to continue through the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;fourth&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; and beyond. Additionally, the Company expects the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic will likely continue to have a material adverse effect on its business, operating results and financial condition during the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;fourth&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; and beyond; however, the precise financial impact and duration cannot be reasonably estimated at this time.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In response to the impact of the COVID-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;19&lt;/div&gt; pandemic, and given the uncertainty of its duration, the Company has taken a number of precautionary measures, including the withdrawal and suspension of its specific full-year fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2020&lt;/div&gt; guidance and the temporary suspension of its quarterly cash dividend.&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

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 <div style="display: inline; font-style: italic; font: inherit;"> December 15, 2022, </div>including interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the standard&#x2019;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the <div style="display: inline; font-style: italic; font: inherit;">first</div> reporting period in which the guidance is adopted.
