<p style="font-size: 10pt; 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-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.</p>

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

<p style="font-size: 10pt; 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-size: 10pt; margin: 0pt 0">The Company has three stock-based compensation plans under which stock options or other
stock-based awards have been granted: the Northern Technologies International Corporation 2019 Stock Incentive 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 and the Northern Technologies International Corporation Employee Stock Purchase Plan. 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">&nbsp;</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. As
of February 29, 2020, options to purchase an aggregate of 300,770 shares of the Company&#8217;s common stock had been granted 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. As of February 29, 2020, 87,447 shares of common stock remained available for sale under the ESPP.</p>

<p style="font-size: 10pt; margin: 0pt 0">The Company granted options to purchase an aggregate of 300,770 and 141,768 shares of
its common stock during the six months ended February 29, 2020 and February 28, 2019, respectively. 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. The Company
recognized compensation expense of $658,470 and $715,960 during the six months ended February 29, 2020 and February 28, 2019, respectively,
related to the options that vested during such time period. As of February 29, 2020, the total compensation cost for non-vested
options not yet recognized in the Company&#8217;s consolidated statements of operations was $700,138. Stock-based compensation
expense of $679,304 is expected through the remainder of fiscal year 2020 and $20,834 is expected to be recognized during fiscal
2021, based on outstanding options as of February 29, 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>

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

<p style="font-size: 10pt; margin: 0pt 0">The Company currently has 19 operating leases for various buildings, equipment and vehicles.
These leases are under non-cancelable operating lease agreements with expiration dates between March 31, 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">&nbsp;</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>

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

<P STYLE="font-size: 10pt; 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&rsquo;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&rsquo;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&rsquo;s percentage of the overall bonus pool is based upon the number of plan participants, the
individual&rsquo;s annual base salary and the individual&rsquo;s position and level of responsibility within the Company. In the
case of each of the Company&rsquo;s executive officer participants, 75% of the amount of their individual bonus payout will be
determined based upon the Company&rsquo;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&rsquo;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&rsquo;s
Board of Directors, upon recommendation of the Compensation Committee, after the completion of the Company&rsquo;s consolidated
financial statements for fiscal 2020. There was $800,000 recognized for management bonuses for the six months ended February 29,
2020, compared to $900,000 recognized for management bonuses for the six months ended February 28, 2019.</P>

(consisting of the Company&#8217;s joint ventures in South Korea, Thailand, France, Germany and India) accounted for 69.6% of the

<p style="font-size: 10pt; 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 February 29, 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">The Company evaluated its February 29, 2020 condensed consolidated financial statements
for subsequent events through the date the condensed consolidated financial statements were issued. As a result of the novel strain
of coronavirus (COVID-19) pandemic and related government mandated restrictions on the Company&rsquo;s business as well as the
businesses of its joint ventures, customers and suppliers, a disruption in the Company&rsquo;s business and the manufacture and
sale of its products and services is expected to occur. Specifically, the operations at NTI China were suspended on January 18,
2020 and did not resume until February 28, 2020. While the disruption is currently expected to be temporary, there is considerable
uncertainty around the duration. The Company expects this matter will likely have a material adverse effect on its business, operating
results and financial condition for the third quarter of fiscal 2020 and beyond; however, the precise financial impact and duration
cannot be reasonably estimated at this time. As of the date of this filing, the Company's U.S. location and its primary suppliers,
continue to be operating. The Company&rsquo;s location in India is currently under mandated governmental shutdown until April
15, 2020.</p></div><p style="font-size: 10pt; margin: 0pt 0"></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 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-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>

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-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">&nbsp;</p>

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

<P STYLE="font-size: 10pt; margin: 0pt 0">NTIC is closely monitoring the novel strain of coronavirus (COVID-19) pandemic and its
potential impact on its business. 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&rsquo;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&rsquo;s location
in India is currently 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&rsquo;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&rsquo;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&rsquo;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&rsquo;s business, operating results and financial
condition.</p>

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

and six months ended February 29, 2020, respectively, compared to the three and six months ended February 28, 2019. NTIC&rsquo;s
consolidated net sales for the three months ended February 29, 2020 were adversely affected by reduced demand in China and other
parts of Asia as a result of the novel strain of coronavirus (COVID-19) outbreak in China. The operations at NTIC China were suspended
on January 18, 2020 and did not resume until February 28, 2020. NTIC anticipates that the COVID-19 outbreak will continue to significantly
adversely affect NTIC&rsquo;s consolidated net sales and earnings in the third quarter of fiscal 2020 and beyond.</P>

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

<P STYLE="font-size: 10pt; margin: 0pt 0">During both the three and six months ended February 29, 2020, 68.1% of NTIC&rsquo;s consolidated
net sales were derived from sales of ZERUST<SUP>&reg;</SUP> products and services, which decreased 1.0% and 1.1% to $9,016,222
and $18,965,734, respectively, compared to $9,108,395 and $19,173,569 during the three and six months ended February 28, 2019,
respectively. These decreases were due to lower sales from existing customers for existing products as a result of decreased demand.
NTIC has focused its sales efforts of ZERUST<SUP>&reg;</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&rsquo;s consolidated net sales for the six months ended February 29, 2020 included $1,587,862 of sales made
to customers in the oil and gas industry compared to $1,343,460 for the six months ended February 28, 2019. Overall demand for
ZERUST<SUP>&reg;</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&rsquo;s sales of ZERUST<SUP>&reg;</SUP>
products and services for the three months ended February 29, 2020 were adversely affected by reduced demand in China and other
parts of Asia as a result of the COVID-19 outbreak in China. NTIC anticipates that the COVID-19 outbreak will continue to significantly
adversely affect sales of ZERUST<SUP>&reg;</SUP> products and services in the third quarter of fiscal 2020 and beyond.</P>

<P STYLE="font-size: 10pt; margin: 0pt 0">During both the three and six months ended February 29, 2020, 31.9% of NTIC&rsquo;s consolidated
net sales were derived from sales of Natur-Tec<SUP>&reg;</SUP> products compared to 31.6% and 30.0% during the three and six months
ended February 28, 2019, respectively. Net sales of Natur-Tec&reg; products increased 0.3% and 8.1% during the three and six months
ended February 29, 2020, respectively, compared to the three and six months ended February 28, 2019 primarily due to an increase
in finished product sales in North America and finished product sales at NTIC&rsquo;s majority-owned subsidiary in India, Natur-Tec
India Private Limited (Natur-Tec India), partially offset by reduced demand in China and other parts of Asia as a result of the
COVID-19 outbreak in China during the three months ended February 29, 2020. NTIC anticipates that the COVID-19 outbreak will continue
to significantly adversely affect sales of Natur-Tec&reg; products in the third quarter of fiscal 2020 and beyond.</P>

<p style="font-size: 10pt; margin: 0pt 0">Cost of goods sold as a percentage of net sales decreased to 65.6% during the three months
ended February 29, 2020, compared to 69.7% during the three months ended February 28, 2019, and decreased to 66.4% during the six
months ended February 29, 2020, compared to 68.4% during the prior fiscal year period primarily as a result of an increased percentage
of product sales from oil and gas products that have higher gross margins than NTIC&#8217;s traditional ZERUST<sup>&#174;</sup>
industrial products.</p>

<p style="margin: 0pt 0; font-size: 10pt">NTIC&#8217;s equity in income from joint ventures decreased 20.7% and 28.6% to $1,360,804
and $2,654,794 during the three and six months ended February 29, 2020, respectively, compared to $1,715,216 and $3,719,378 during
the three and six months ended February 28, 2019, respectively. These decreases were primarily due to corresponding decreases in
net sales at the joint ventures, which decreased 12.5% and 14.6% to $24,289,370 and $49,749,664 during the three and six months
ended February 29, 2020, respectively, compared to $27,749,880 and $58,229,806 during the three and six months ended February 28,
2019, respectively. These decreases in net sales of NTIC&#8217;s joint ventures were primarily due to lower sales from existing
customers 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 decrease significantly as a result of anticipated decreased
demand as a result of the COVID-19 outbreak and may have a significant adverse effect on NTIC&#8217;s equity in income from its
joint ventures commencing in the third quarter of fiscal 2020.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC&#8217;s total operating expenses increased 19.7% and 6.8% to $6,461,748 and $12,360,368
during the three and six months ended February 29, 2020, respectively, compared to $5,396,155 and $11,575,203 for the three and
six months ended February 28, 2019. This increase was primarily due to an increase in NTIC&#8217;s personnel expenses.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC spent $1,006,395 and $1,968,036 during the three and six months ended February 29,
2020, compared to $927,537 and $1,799,694 during the three and six months ended February 28, 2019, respectively, in connection
with its research and development activities. NTIC anticipates that it will spend a total of between $3,500,000 and $3,700,000
in fiscal 2020 on research and development activities.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">Net income attributable to NTIC decreased to $179,834, or $0.02 per diluted common share,
for the three months ended February 29, 2020, compared to $1,401,568, or $0.15 per diluted common share, for the three months ended
February 28, 2019, a decrease of $1,212,734, or $0.13 per diluted share. Net income attributable to NTIC decreased to $1,392,384,
or $0.15 per diluted common share, for the six months ended February 29, 2020, compared to $2,898,627, or $0.31 per diluted common
share, for the six months ended February 28, 2019, a decrease of $1,506,243, or $0.16 per diluted share. These decreases were primarily
the result of the increase in operating expenses and decrease in income from joint venture operations during the current fiscal
year periods compared to the prior fiscal year periods, partially offset by increases in gross profit.</p>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC anticipates that its earnings may be significantly adversely affected by COVID-19
in the third quarter of fiscal 2020 and beyond 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>Net Sales</I>. NTIC&rsquo;s consolidated net sales decreased 0.6% and increased 1.7%
to $13,233,783 and $27,865,183 during the three and six months ended February 29, 2020, respectively, compared to the three and
six months ended February 28, 2019. NTIC&rsquo;s consolidated net sales for the three months ended February 29, 2020 were adversely
affected by reduced demand in China and other parts of Asia as a result of the COVID-19 outbreak in China. The operations at NTIC
China were suspended on January 18, 2020 and did not resume until February 28, 2020. NTIC&rsquo;s consolidated net sales to unaffiliated
customers excluding NTIC&rsquo;s joint ventures increased 3.0% and 3.1% to $12,988,153 and $27,033,937 during the three and six
months ended February 29, 2020, respectively, compared to the same respective periods in fiscal 2019. These increases were primarily
a result of an increase in sales of Zerust oil &amp; gas and Natur-Tec<SUP>&reg;</SUP> products. Net sales to joint ventures decreased
65.4% and 30.3% to $245,630 and $831,246, during the three and six months ended February 29, 2020, respectively, compared to the
same respective periods in fiscal 2019. These decreases were primarily a result of decreased demand and the timing of shipments
compared to the prior fiscal year periods.</p>

<P STYLE="font-size: 10pt; margin: 0pt 0">NTIC&rsquo;s total ZERUST<SUP>&reg;</SUP> net sales decreased during the three months
and six months ended February 29, 2020, compared to the prior fiscal year periods, primarily due to an overall decreased demand
for ZERUST<SUP>&reg;</SUP> industrial products and services in North America, partially offset by increased demand for ZERUST<SUP>&reg;
</SUP>oil and gas products and services. NTIC&rsquo;s sales of ZERUST<SUP>&reg;</SUP> products and services for the three months
ended February 29, 2020 were adversely affected by reduced demand in China and other parts of Asia as a result of the COVID-19
outbreak in China.</p>

<p style="margin: 0pt 0; font-size: 10pt">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 may have a significant adverse effect on sales of ZERUST<sup>&#174;</sup>
products and services in the third quarter of fiscal 2020 and beyond. 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">During both the three and six months ended February 29, 2020, 31.9% of NTIC&rsquo;s
consolidated net sales were derived from sales of Natur-Tec<SUP>&reg;</SUP> products, which increased 0.3% and 8.1% to $4,217,561
and $8,899,449 during the three and six months ended February 29, 2020, respectively, compared to the three and six months ended
February 28, 2019. These increases were primarily due to an increase in finished product sales in North America and finished product
sales at NTIC&rsquo;s majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India), partially offset
by decreased demand in China and other parts of Asia as a result of the COVID-19 outbreak in China during the three months ended
February 29, 2020. NTIC anticipates that the COVID-19 outbreak will continue to significantly adversely affect sales of Natur-Tec<SUP>&reg;
</SUP>products in the third quarter of fiscal 2020 and beyond.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Cost of Goods Sold</i>. Cost of goods sold decreased 6.4% and 1.3% for the three and
six months ended February 29, 2020, respectively, compared to the three and six months ended February 28, 2019. Cost of goods sold
as a percentage of net sales decreased to 65.6% during the three months ended February 29, 2020, compared to 69.7% during the three
months ended February 28, 2019, and decreased to 66.4% during the six months ended February 29, 2020, compared to 68.4% during
the six months ended February 28, 2019. These increases were due primarily to an increased percentage of product sales from ZERUST<sup>&#174;</sup>
oil and gas products that have higher gross margins than NTIC&#8217;s traditional ZERUST<sup>&#174;</sup> industrial products.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Equity in Income from Joint Ventures.</i> NTIC&#8217;s equity in income from joint
ventures decreased 20.7% to $1,360,804 and 28.6% to $2,654,794 during the three and six months ended February 29, 2020, respectively,
compared to $1,715,216 and $3,719,378 during the three and six months ended February 28, 2019, respectively. These decreases were
primarily a result of declining profitability of the joint ventures during the respective periods based on decreases in net sales.
Of the total equity in income from joint ventures, NTIC had equity in income from joint ventures of $1,710,390 attributable to
EXCOR during the six months ended February 29, 2020, compared to $2,740,907 during the six months ended February 28, 2019. NTIC
had equity in income of all other joint ventures of $944,404 during the six months ended February 29, 2020, compared to $978,471
during the six months ended February 28, 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</i>. NTIC recognized fee income for services
provided to joint ventures of $1,256,213 and $2,614,538 during the three and six months ended February 29, 2020, respectively,
compared to $1,436,774 and $2,865,209 during the three and six months ended February 28, 2019, respectively, representing decreases
of 12.6% and 8.7%, 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 to $24,289,370 and $49,749,664 during
the three and six months ended February 29, 2020, respectively, compared to $27,749,880 and $58,229,806 during the three and six
months ended February 28, 2019, respectively, representing decreases of 12.5% and 14.6%, 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 $420,229 were attributable to EXCOR during the six months ended February 29, 2020, compared to $430,328
attributable to EXCOR during the six months ended February 28, 2019. NTIC anticipates that net sales of its joint ventures may
decrease significantly as a result of anticipated decreased demand as a result of the COVID-19 outbreak and is expected to have
a significant adverse effect on NTIC&#8217;s equity in income from its joint ventures for the third quarter of fiscal 2020 and
beyond.</p>

the three and six months ended February 29, 2020, respectively, compared to the same respective periods in fiscal 2019 due primarily
to increases in operating expenses associated with ZERUST<sup>&#174;</sup> sales efforts, consisting primarily of selling and personnel
expenses. Selling expenses as a percentage of net sales increased to 23.5% and 21.5% for the three and six months ended February
29, 2020, respectively, from 18.8% and 19.4% for the three and six months ended February 28, 2019, respectively, primarily due

increased 19.4% and decreased 1.4% for the three and six months ended February 29, 2020, respectively, compared to the same respective

$3,695,321 for the three and six months ended February 28, 2019, respectively.</p>

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

<P STYLE="font-size: 10pt; margin: 0pt 0"><I>Income Tax Expense</I>. Income tax expense was $463,594 and $727,660 for the
three and six months ended February 29, 2020, respectively, compared to income tax expense of $246,371 and $502,074 during
the three and six months ended February 28, 2019, respectively. Income tax expense was calculated based on management&rsquo;s
estimate of NTIC&rsquo;s annual effective income tax rate. The quarter-over-quarter increase in the Company&rsquo;s effective
income tax rate is primarily due to foreign withholding taxes paid on dividends received from NTIC&rsquo;s joint ventures
during the quarter. Dividends received from NTIC&rsquo;s joint ventures do not represent a component of income before income
tax expense. Therefore, to the extent dividends received from NTIC&rsquo;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>

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

<p style="font-size: 10pt; margin: 0pt 0">NTIC considers the earnings of certain foreign joint ventures 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 $19,267,931 and $22,178,126 at February 29, 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>

<p style="font-size: 10pt; margin: 0pt 0">As of February 29, 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">&nbsp;</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

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 February 29, 2020, NTIC was in compliance with all debt covenants.</p>

for sale securities, forecasted cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC

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 capital contributions to new and existing subsidiaries and joint ventures. NTIC&#8217;s joint ventures traditionally have operated

<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. 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>

by a non-controlling interest and proceeds from NTIC&rsquo;s employee stock purchase plan.</p>

<p style="font-size: 10pt; margin: 0pt 0"><i>Share Repurchase Plan</i>. On January 15, 2015, NTIC&#8217;s Board of Directors authorized
the repurchase of up to $3,000,000 in shares of NTIC common stock through open market purchases or unsolicited or solicited privately
negotiated transactions. This program has no expiration date but may be terminated by NTIC&#8217;s Board of Directors at any time.
No repurchases occurred during the six months ended February 29, 2020. As of February 29, 2020, up to $2,640,548 in shares of NTIC
common stock remained available for repurchase under NTIC&#8217;s stock repurchase program.</p>

a cash dividend of $0.065 per share of NTIC&rsquo;s common stock, payable on February 19, 2020, to stockholders of record on February
5, 2020. This was an increase compared to the cash dividend of $0.06 per share of NTIC&rsquo;s common stock declared and paid
during the quarter ended February 28, 2019. The declaration of future dividends is not guaranteed and will be determined by NTIC&rsquo;s
Board of Directors in light of conditions then existing, including NTIC&rsquo;s earnings, financial condition, cash requirements,
restrictions in financing agreements, business conditions, and other factors, including without limitation the effect of COVID-19
on its business, operating results and financial condition.</p>

<p style="margin: 0pt 0; font-size: 10pt"><i>Stock Split</i>. On June 3, 2019, NTIC&#8217;s Board of Directors declared a two-for-one
stock split of NTIC&#8217;s common stock effected in the form of a 100% share dividend distributed on June 28, 2019 to record holders
as of June 17, 2019. As a result of this action, approximately 4.5 million shares were issued to stockholders of record as of June
17, 2019. The par value of the common stock remains at $0.02 per share, and, accordingly, approximately $90,900 was transferred
from additional paid-in capital to common stock. Net income and dividends declared per share and weighted average shares outstanding
presented in this report reflect the 100 percent stock dividend. The two-for-one stock split is reflected in the share amounts
in all periods presented in this report.</p>

an aggregate of approximately $500,000 to $700,000 on capital expenditures during fiscal 2020, which it expects will relate primarily
to the purchase of new equipment.</p>

<p style="font-size: 10pt; margin: 0pt 0">NTIC does not have any relationships with unconsolidated entities or financial partnerships,
such as entities often referred to as structured finance or special purpose entities, which are established for the purpose of
facilitating off-balance sheet financial arrangements. As such, NTIC is not materially exposed to any financing, liquidity, market,
or credit risk that could arise if NTIC had engaged in such arrangements.</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 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 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 some 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>

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 February 29, 2020, NTIC had no borrowings under the line of credit.</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 February 29, 2020, NTIC had no borrowings under the line of credit.</p>

discloses the following additional risk:</p>

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

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

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

<P STYLE="font-size: 10pt; 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&rsquo;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&rsquo;s location
in India is currently 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&rsquo;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&rsquo;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&rsquo;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&rsquo;s business, operating results and financial
condition.</p>

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

These leases are under non-cancelable operating lease agreements with expiration dates between &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2020 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt; or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt;-year term(s) and has the right of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; leases with terms less than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&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-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-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;842.&lt;/div&gt; Additionally, the Company did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&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; text-align: left; text-indent: 0in; margin: 0pt 0"&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-size: 10pt; text-align: left; text-indent: 0in; 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="white-space: nowrap; 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="white-space: nowrap; font-size: 10pt; font-weight: bold; text-align: center; border-bottom: Black 1pt solid"&gt;February 29, 2020&lt;/td&gt; &lt;/tr&gt; &lt;tr style="vertical-align: bottom; background-color: rgb(204,238,255)"&gt; &lt;td style="width: 82%; 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: 15%; font-size: 10pt; text-align: right"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;520,601&lt;/div&gt;&lt;/td&gt; &lt;td style="white-space: nowrap; 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="white-space: nowrap; 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-weight: inherit; font-style: normal;"&gt;211,495&lt;/div&gt;&lt;/td&gt; &lt;td style="white-space: nowrap; 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-weight: inherit; font-style: normal;"&gt;309,106&lt;/div&gt;&lt;/td&gt; &lt;td style="white-space: nowrap; 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: 55.45pt"&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-weight: inherit; font-style: normal;"&gt;520,601&lt;/div&gt;&lt;/td&gt; &lt;td style="white-space: nowrap; 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; text-align: justify; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-align: justify; text-indent: 0in; margin: 0pt 0"&gt;As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;29,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020,&lt;/div&gt; the weighted-average remaining lease term was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2.1&lt;/div&gt; years. The Company&amp;#x2019;s lease agreements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; provide a readily determinable implicit rate nor is it available to the Company from its lessors.

font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt; August 31, 2020. &lt;/div&gt;For fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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, 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-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;2020&lt;/div&gt; compared to a pre-established target EBITOI for fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020,&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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 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.

As a result of the novel strain of coronavirus (COVID-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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, a disruption in the Company&amp;#x2019;s business and the manufacture and sale of its products and services is expected to occur. Specifically, the operations at NTI China were suspended on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 18, 2020 &lt;/div&gt;and did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; resume until &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 28, 2020. &lt;/div&gt;While the disruption is currently expected to be temporary, there is considerable uncertainty around the duration. The Company expects this matter will likely have a material adverse effect on its business, operating results and financial condition for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;third&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020&lt;/div&gt; and beyond; however, the precise financial impact and duration cannot be reasonably estimated at this time. As of the date of this filing, the Company's U.S. location and its primary suppliers, continue to be operating. The Company&amp;#x2019;s location in India is currently under mandated governmental shutdown until &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 15, 2020.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:SubsequentEventsTextBlock>
