in &#8220;Note 1. Nature of Business and Significant Accounting Policies&#8221; of the Company&#8217;s Annual Report on Form 10-K
for the year ended August 31, 2018. In May 2014, the Financial Accounting Standards Board (FASB) issued guidance creating Accounting
Standards Codification (ASC) Section 606, <i>Revenue from Contracts with Customers</i> (ASC 606), which establishes a comprehensive
new model for the recognition of revenue from contracts with customers. This model is based on the core principle that revenue
should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration
to which the entity expects to be entitled in exchange for those goods or services.</p>

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

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The adoption of ASC 606 neither impacted the previously reported
financial statements in any prior period nor did it result in a cumulative effect adjustment to retained earnings. Therefore, the
adoption of the standard did not impact the Company&#8217;s revenue recognition process. Generally, the Company&#8217;s performance
obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination
depending on the terms of the contracts. The Company&#8217;s services are generally sold based upon quotes or contracts with customers
that include a fixed or determinable price, and sales arrangements do not contain any significant financing component for its customers.
The Company does not recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer
arrangements do not generate contract assets or liabilities.</p>

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

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

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Revenue Recognition</i> - Revenue is measured based on consideration
specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting
the transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components.
While most of the Company&#8217;s revenue is contracted with customers through one-time purchase orders and short-term contracts,
the Company does have long-term arrangements with certain customers. Revenue from all customers is recognized when a performance
obligation is satisfied by transferring control of a distinct good or service to a customer.</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">Individually promised goods and services in a contract are considered
a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service
on its own or with other resources that are readily available to the customer and the good or service is separately identifiable
from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated
between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered
are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily
of direct labor, manufacturing overhead, materials, and components. The Company does not incur significant upfront costs to obtain
a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense
in a manner consistent with the related recognition of revenue.</p>

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

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The timing of revenue recognition, billing, and cash collections
results in accounts receivable on the balance sheet.</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"><i>Performance Obligations</i> - A performance obligation is
a promise in a contract to transfer a distinct good or service to the customer. A contract&#8217;s transaction price is allocated
to each distinct performance obligation in proportion to its standalone selling price and recognized as revenue when, or as, the
performance obligation is satisfied. The Company&#8217;s various performance obligations and the timing or method of revenue recognition
are discussed below.</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 sells its products to both distributors and end-users.
Each unit of product delivered under a customer order represents a distinct and separate performance obligation, as the customer
can benefit from each unit on its own or with other resources that are readily available to the customer, and each unit of product
is separately identifiable from other products in the arrangement.</p>

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

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

    <!-- Field: /Page -->

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

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

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Trade Receivables</i> - Trade receivables include amounts
invoiced and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company records
an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. The allowance
is based on a review of all outstanding amounts on an on-going basis. Management determines the allowance for doubtful accounts
by regularly evaluating individual customer receivables and considers a customer&#8217;s financial condition, credit history, and
current economic conditions. Trade receivables are written off when deemed uncollectible and have been historically insignificant.
Recoveries of trade receivables previously written off are recorded when received. Accounts are considered past due if payment
is not received according to agreed-upon terms.</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"><i>Sales Commissions</i> - Sales commissions paid to sales representatives
are eligible for capitalization, as they are incremental costs that would not have been incurred without entering into a specific
sales arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical
expedient provided by ASC 340-40-25-4 and recognize the incremental costs of obtaining contracts as an expense when incurred, as
the amortization period of the assets that would have otherwise been recognized is one year or less. The Company records these
costs as a selling expense.</p>

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

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

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>International Revenue</i> - The Company markets its products
to numerous countries in North America, Europe, Latin America, Asia, and other parts of the world. See Note 11, Segment and Geographical
Information, for information regarding revenue disaggregation by geography.</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"><i>Recently Issued Accounting Pronouncements</i></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 February 2016, the FASB issued Accounting Standards Update
(ASU) No. 2016-02, <i>Leases</i>. ASU No. 2016-02 was issued to increase transparency and comparability among organizations by
recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use
asset (as defined). ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods
within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively
to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The guidance will be
effective for the Company&#8217;s first quarter of fiscal year 2020. The Company is currently assessing the effect that ASU No.
2016-02 will have on its consolidated financial statements but does not expect it will have a material impact on its consolidated
balance sheet.</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
will be effective for the Company&#8217;s fiscal year 2020, with the option for early adoption at any time prior to the effective
date. It must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in
the U.S. federal corporate income tax rate in the Tax Reform Act is recognized. The Company is currently assessing the impact this
new accounting guidance will have on its consolidated financial statements.</p>

Association (PNC Bank) of $3,000,000. No amounts were outstanding under the line of credit as of either May 31, 2019 or August
31, 2018. At the option of the Company, outstanding advances under the line of credit bear interest at either (a) an annual rate
based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by the Company or (b) at the rate publicly announced
by PNC Bank from time to time as its prime rate.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The line of credit is governed under a loan agreement. The loan
agreement contains standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge
coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity
investments, disposition of assets, mergers and consolidations, and other matters customarily restricted in such agreements. Under
the loan agreement, the Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00. As of May 31, 2019, the Company
was in compliance with all debt covenants.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The revolving credit facility allows the Company to request

letters of credit balance as of May 31, 2019 and August 31, 2018 with PNC Bank. The availability of advances under the line of
credit will be reduced by the face amount of any letter of credit issued and outstanding (whether or not drawn) under the revolving
credit facility.&nbsp;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company held its 2019 Annual Meeting of Stockholders (2019
Annual Meeting) on January 18, 2019. At the 2019 Annual Meeting, a proposal to ratify an amendment to the Company&#8217;s Restated
Certificate of Incorporation to increase the Company&#8217;s authorized shares of common stock from 10,000,000 to 15,000,000 (Share
Increase Amendment) was approved by the Company&#8217;s stockholders by the required vote. The proposal to approve the Share Increase
Amendment was initially voted on and approved at the 2018 Annual Meeting of Stockholders. However, because the description of the
authority of brokers to vote on proposals without instruction in the proxy statement for the 2018 Annual Meeting of Stockholders
could have created some uncertainty as to the effect of the vote obtained at last year&#8217;s meeting, and out of an abundance
of caution, the Board requested that stockholders at the 2019 Annual Meeting ratify the filing and effectiveness of the Certificate
of Amendment to the Company&#8217;s Restated Certificate of Incorporation, which was filed with the Secretary of State of the State
of Delaware on January 16, 2018, pursuant to Delaware law, in order to eliminate any uncertainty related to the effectiveness of
the share increase amendment. Since the ratification proposal was approved by stockholders at the 2019 Annual Meeting, the ratification
was retroactive to January 16, 2018, the time of filing of the Share Increase Amendment with the Secretary of State of the State
of Delaware.</p>

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
three- or four-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 May 31, 2019, only stock options and stock bonuses had been granted under the 2007 Plan and no stock

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On August 31, 2018, 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, 2019. For fiscal 2019, as in past years, the total amount
available under the bonus plan for all plan participants, including executive officers, is dependent upon the Company&#8217;s earnings
before interest, taxes, and other income, as adjusted to take into account amounts to be paid under the bonus plan and certain
other adjustments (Adjusted EBITOI). Each plan participant&#8217;s percentage of the overall bonus pool is based upon the number
of plan participants, the individual&#8217;s annual base salary, and the individual&#8217;s position and level of responsibility
within the Company. In the case of each of the Company&#8217;s executive officer participants, 75% of the amount of their individual
bonus payout will be determined based upon the Company&#8217;s actual EBITOI for fiscal 2019 compared to a pre-established target
EBITOI for fiscal 2019 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 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 2019. There was $1,450,000 accrued for management bonuses for the nine months ended May 31, 2019,
compared to $1,380,000 accrued for management bonuses for the nine months ended May 31, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Two joint ventures (consisting of the Company&#8217;s joint
ventures in South Korea and Germany) accounted for 76.4% of the Company&#8217;s trade joint venture receivables at May 31, 2019,
and three joint ventures (consisting of the Company&#8217;s joint ventures in South Korea, Thailand, and India) accounted for 74.1%
of the Company&#8217;s trade joint venture receivables at August 31, 2018.</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, 2019, 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>

reducing the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018, generally eliminating U.S. federal income
taxes on dividends received from foreign subsidiaries and joint ventures after December 31, 2017, and imposing a one-time deemed

<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&#174; brand. NTIC has been selling
its proprietary ZERUST&#174; 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&#174; 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), its majority-owned subsidiary in Brazil, Zerust Preven&#231;&#227;o de Corros&#227;o S.A. (Zerust Brazil), its
wholly-owned subsidiary in Mexico, ZERUST-EXCOR MEXICO, S. de R.L. de C.V (Zerust Mexico), 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&#174; 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&#174; 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>

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. Internationally, NTIC sells its Natur-Tec<sup>&#174;</sup> resin compounds
and finished products both directly and through its majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC receives funds from its joint ventures for fees received
for services that NTIC provides 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">NTIC&#8217;s consolidated net sales increased 15.2% and 15.3%
during the three and nine months ended May 31, 2019, respectively, compared to the three and nine months ended May 31, 2018. These
increases were primarily a result of an increase in sales of Natur-Tec&#174; products.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During the three and nine months ended May 31, 2019, 67.7% and
69.1% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of ZERUST&#174; products and services, which
decreased 2.9% and 2.8% to $10,077,203 and $29,250,772 during the three and nine months ended May 31, 2019, respectively, compared
to $10,382,884 and $30,102,080 during the three and nine months ended May 31, 2018, respectively. These decreases were due to lower
sales from existing customers for products as a result of decreased demand. NTIC has focused its sales efforts of ZERUST&#174; 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, 2019 included $2,225,490 of sales made to customers in the oil and gas industry compared to $1,418,573 for
the nine months ended May 31, 2018. Overall demand for ZERUST&#174; 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.</p>

and 98.4% during the three and nine months ended May 31, 2019, respectively, compared to the three and nine months ended May 31,

and $5,793,391 during the three and nine months ended May 31, 2018, respectively. These decreases were primarily due to corresponding
decreases in net sales at the joint ventures, which decreased 11.8% and 4.7% to $27,774,112 and $86,003,918 during the three and
nine months ended May 31, 2019, respectively, compared to $31,480,885 and $90,200,146 for the three and nine months ended May 31,
2018, respectively. These decreases in net sales of NTIC&#8217;s joint ventures were primarily due to decreased 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.</p>

for the three and nine months ended May 31, 2018, respectively. These increases were primarily due to an increase in NTIC&#8217;s
personnel expenses. Operating expenses, as a percent of net sales, for the three months ended May 31, 2019 were 42.3%, compared
to 43.6% for the same period last fiscal year and for the nine months ended May 31, 2019 were 42.2%, compared to 45.3% for the
same period last fiscal year. These reductions in operating expenses, as a percent of net sales, were primarily due to significantly
higher net sales, partially offset by higher operating expenses.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC spent $1,005,045 and $2,804,739 during the three and nine

respectively, in connection with its research and development activities. NTIC anticipates that it will spend a total of between
$3,400,000 and $3,600,000 in fiscal 2019 on research and development activities.</p>

for the three months ended May 31, 2018, a decrease of $660,603 or $0.07 per diluted share. Net income attributable to NTIC decreased
3.9% to $4,380,776, or $0.46 per diluted common share, for the nine months ended May 31, 2019 compared to $4,559,225, or $0.49
per diluted common share, for the nine months ended May 31, 2018, a decrease of $178,449 or $0.03 per diluted share. These decreases
were primarily the result of the increase in operating expenses and decrease in joint venture operations during the current fiscal
year periods compared to the prior fiscal year periods, partially offset by the increase in gross margin and decrease in tax expense,
specifically the $700,000 one-time provisional adjustment related to the Tax Cuts and Jobs Act (Tax Reform Act) that occurred in
the second quarter of fiscal year 2018, as described in more detail below.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC&#8217;s total ZERUST&#174; net sales decreased during the
three months and nine months ended May 31, 2019, compared to the prior fiscal year periods, primarily due to an overall decreased
demand for ZERUST&#174; industrial products and services in North America and China, partially offset by increased demand for ZERUST&#174;
oil and gas products and services. NTIC anticipates that its sales of ZERUST&#174; 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 ZERUST&#174; 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>

30.9% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of Natur-Tec&#174; products, which increased
89.5% and 98.4% to $4,815,914 and $13,051,801 during the three and nine months ended May 31, 2019, respectively, compared to the
three and nine months ended May 31, 2018. These increases were primarily due to an increase in finished product sales in North
America and finished product sales at NTIC&#8217;s majority-owned subsidiary in India, Natur-Tec India.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Cost of Goods Sold</i>. Cost of goods sold increased 18.0%
and 17.9% for the three and nine months ended May 31, 2019, respectively, compared to the three and nine months ended May 31, 2018.
Cost of goods sold as a percentage of net sales increased to 68.1% during the three months ended May 31, 2019 compared to 66.5%
during the three months ended May 31, 2018 and increased to 68.3% during the nine months ended May 31, 2019 compared to 66.8% during
the nine months ended May 31, 2018. These increases were due primarily to an increased percentage of product sales from Natur-Tec&#174;
products that have lower gross margins than NTIC&#8217;s traditional ZERUST&#174; industrial products.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Equity in Income from Joint Ventures.</i> NTIC&#8217;s equity
in income from joint ventures decreased 16.4% and 3.4% to $1,877,410 and $5,596,788 during the three and nine months ended May
31, 2019, respectively, compared to $2,246,066 and $5,793,391 during the three and nine months ended May 31, 2018, 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 $4,094,763
attributable to EXCOR during the nine months ended May 31, 2019 compared to $4,138,814 during the nine months ended May 31, 2018.
NTIC had equity in income of all other joint ventures of $1,502,025 during the nine months ended May 31, 2019 compared to $1,654,577
during the nine months ended May 31, 2018.</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 $1,433,823 and $4,299,032 during the three and nine months ended May 31,
2019, respectively, compared to $1,508,500 and $4,624,532 during the three and nine months ended May 31, 2018, respectively, representing
decreases of 5.0% and 7.0%, 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 $27,774,112 and $86,003,918
during the three and nine months ended May 31, 2019, respectively, compared to $31,480,885 and $90,200,146 during the three and
nine months ended May 31, 2018, respectively, representing decreases of $3,706,773 and $4,196,228, 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 $643,154 were attributable to EXCOR during the nine months ended May 31, 2019 compared to $680,939 attributable
to EXCOR during the nine months ended May 31, 2018.</p>

0.8% and increased 0.6% for the three and nine months ended May 31, 2019, respectively, compared to the same respective periods
in fiscal 2018 due primarily to increases in operating expenses associated with ZERUST&#174; sales efforts, consisting primarily
of selling and personnel expenses. Selling expenses as a percentage of net sales decreased to 18.5% and 19.1% for the three and
nine months ended May 31, 2019, respectively, from 21.5% and 21.9% for the three and nine months ended May 31, 2018, respectively,
primarily due to the increase in net sales, as previously described.</p>

and administrative expenses increased 27.1% and 16.2% for the three and nine months ended May 31, 2019, respectively, compared
to the same respective periods in fiscal 2018 primarily due to increased personnel costs. As a percentage of net sales, general
and administrative expenses increased to 17.0% and 16.5% for the three and nine months ended May 31, 2019, respectively, from 15.4%
and 16.4% for the same respective periods in fiscal 2018. The increases in general and administrative expenses as a percentage
of net sales for the three and six month comparisons were primarily due to the increase in net sales, as previously described.</p>

to $2,485,702 and $6,052,814 for the three and nine months ended May 31, 2018, respectively.</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"><i>Income Tax Expense</i>. Income tax expense was $150,257 and
$652,331 for the three and nine months ended May 31, 2019, respectively, compared to income tax expense of $181,683 and $1,128,583
during the three and nine months ended May 31, 2018, respectively. Income tax expense was calculated based on management&#8217;s
estimate of NTIC&#8217;s annual effective income tax rate. The effective tax rate for the three and nine months ended May 31, 2019
was 8.4% and 11.9%, respectively, compared to 7.3% and 18.6% for the three and nine months ended May 31, 2018, respectively. These
decreases were primarily due to one-time provisional adjustments related to the Tax Reform Act during the prior fiscal year periods.
The Tax Reform Act, among other things, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018,
generally eliminated U.S. federal income taxes on dividends received from foreign subsidiaries and joint ventures after December
31, 2017, and imposed a one-time deemed repatriation tax on certain unremitted earnings of foreign subsidiaries and joint ventures.
As a result of the change in the tax law, a one-time non-cash tax provisional charge of $700,000 related to the re-measurement
of deferred tax assets and liabilities was recorded in the nine months ended May 31, 2018. The impact of this non-cash tax charge
increased NTIC&#8217;s effective rate by approximately 30.3% for the nine months ended May 31, 2018.</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 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 $22,048,149 and $20,921,783 at May 31, 2019, and August 31, 2018, 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: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><i>Net Income Attributable to NTIC</i>. Net income attributable
to NTIC decreased to $1,482,149, or $0.16, per diluted common share, for the three months ended May 31, 2019 compared to $2,142,752,
or $0.23, per diluted common share, for the three months ended May 31, 2018. Net income attributable to NTIC decreased to $4,380,776,
or $0.46 per diluted common share, for the nine months ended May 31, 2018 compared to $4,559,225, or $0.49 per diluted common share,
for the nine months ended May 31, 2018. These decreases were primarily the result of the increase in operating expenses and decrease
in joint venture operations during the current fiscal year periods compared to the prior fiscal year periods, partially offset
by the increase in gross margin and decrease in tax expense, specifically the $700,000 one-time provisional adjustment related
to the Tax Cuts and Jobs Act (Tax Reform Act) that occurred in the second quarter of fiscal year 2018, as described in more detail
below.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">As of May 31, 2019, 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 November 30, 2018, the Company and PNC
Bank extended the maturity date of the line of credit from January 7, 2019, to January 7, 2020. 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.
The line of credit is evidenced by an amended and restated committed line of credit note in the principal amount of up to $3,000,000.
The line of credit has a $1,200,000 standby letter of credit sub-facility, with any standby letters of credit issued thereunder
being at the sole discretion of PNC Bank. Any lines of credit issued by PNC Bank would decrease the availability under the revolving
line of credit. The line of credit is subject to standard covenants, including affirmative financial covenants, such as the maintenance
of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional
indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted
in such agreements. Under the loan agreement, NTIC is subject to a minimum fixed charge coverage ratio of 1.10:1.00. As of May

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC believes that a combination of its existing cash and cash
equivalents, available for sale securities, forecasted cash flows from future operations, anticipated distributions of earnings,
anticipated fees to NTIC for services provided to its joint ventures, and funds available through existing or anticipated financing
arrangements will be adequate to fund its existing operations, investments in new or existing joint ventures or subsidiaries, capital
expenditures, debt repayments, cash dividends, and any stock repurchases for at least the next 12 months. During the remainder
of fiscal 2019, NTIC expects to continue to invest in NTIC China, research and development, and in marketing efforts and resources
for the application of its corrosion prevention technology in the oil and gas industry and its Natur-Tec&#174; bio-plastics business,
although the amounts of these various investments are not known at this time. In order to take advantage of such new product and
market opportunities to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing
under its revolving line of credit or raising additional financing through the issuance of debt or equity securities. There is
no assurance that any financing transaction will be available on terms acceptable to NTIC, or at all, or that any financing transaction
will not be dilutive to NTIC&#8217;s current stockholders.</p>

investments and capital contributions to new and existing subsidiaries and joint ventures. NTIC&#8217;s joint ventures traditionally
have operated with little or no debt and have been self-financed with minimal initial capital investment and minimal additional
capital investment from their respective owners. Therefore, NTIC believes there is limited exposure by NTIC&#8217;s joint ventures
that could materially impact their respective operations and/or liquidity.</p>

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>

in inventory as of May 31, 2019, compared to August 31, 2018. Trade receivables, excluding joint ventures, as of May 31, 2019 increased
$148,524 compared to August 31, 2018, primarily related to the timing of collections and the increase in sales. Outstanding trade
receivables, excluding joint ventures balances as of May 31, 2019 increased 2 days to an average of 67 days from balances outstanding
from these customers as of August 31, 2018. Outstanding trade receivables from joint ventures as of May 31, 2019 increased $174,179
compared to August 31, 2018 primarily due to the timing of payments. Outstanding balances from trade receivables from joint ventures
decreased an average of 22 days to an average of 77 days from balances outstanding from these customers compared to August 31,
2018. The average days outstanding of trade receivables from joint ventures as of May 31, 2019 were primarily due to the receivable
balances at NTIC&#8217;s joint ventures in South Korea and Germany.</p>

little effect on NTIC. Although NTIC&#8217;s business historically has not been seasonal, NTIC believes there is some seasonality

<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, Indian Rupee, Chinese Renminbi, 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>

rate, and thus may subject NTIC to some market risk on interest rates. As of May 31, 2019, NTIC had no borrowings under the line

<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>

rate and, thus, may subject NTIC to some market risk on interest rates. As of May 31, 2019, NTIC had no borrowings under the line
of credit.</p>

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;2019&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;2019&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 payment of bonuses under the plan is discretionary and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; There was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,450,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019, &lt;/div&gt;compared to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,380,000&lt;/div&gt; accrued for management bonuses for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2018.&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;Two joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea and Germany) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;76.4%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019, &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; joint ventures (consisting of the Company&amp;#x2019;s joint ventures in South Korea, Thailand, and India) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;74.1%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2018.&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-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; probable or the amount is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have been incurred. In the opinion of management, as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019, &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-weight: inherit; font-style: normal;"&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>

Under the loan agreement, the Company is subject to a minimum fixed charge coverage ratio of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1.10:1.00.&lt;/div&gt; As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019, &lt;/div&gt;the Company was in compliance with all debt covenants.&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 revolving credit facility allows the Company to request that PNC Bank issue letters of credit up to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1,200,000.&lt;/div&gt; The Company did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have any letters of credit reserved against the available letters of credit balance as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2018 &lt;/div&gt;with PNC Bank.

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.&lt;/div&gt; &lt;div style=" font: 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;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 1, 2018, &lt;/div&gt;the Company adopted ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt; for all customer contracts using the modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606,&lt;/div&gt; the Company performs the following &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt; steps: (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&lt;/div&gt;) identify the contracts with a customer; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2&lt;/div&gt;) identify the performance obligations in the contract; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;3&lt;/div&gt;) determine the transaction price; (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;4&lt;/div&gt;) allocate the transaction price to the performance obligations in the contract; and (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;5&lt;/div&gt;) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 9 --&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 adoption of ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt; neither impacted the previously reported financial statements in any prior period nor did it result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; impact the Company&amp;#x2019;s revenue recognition process. Generally, the Company&amp;#x2019;s performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company&amp;#x2019;s services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; contain any significant financing component for its customers. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer arrangements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; generate contract assets or liabilities.&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;Changes to the Company&amp;#x2019;s significant accounting policies as a result of adopting ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt; are discussed below.&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;Revenue Recognition&lt;/div&gt; - Revenue is measured based on consideration specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components. While most of the Company&amp;#x2019;s revenue is contracted with customers through &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-time purchase orders and short-term contracts, the Company does have long-term arrangements with certain customers. Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer.&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;Individually promised goods and services in a contract are considered a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; incur significant upfront costs to obtain a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with the related recognition of revenue.&lt;/div&gt; &lt;div style=" font: 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 excludes government assessed and imposed taxes on revenue generating transactions that are invoiced to customers from revenue. The Company includes freight billed to customers in revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.&lt;/div&gt; &lt;div style=" font: 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 timing of revenue recognition, billing, and cash collections results in accounts receivable on the balance sheet.&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;Performance Obligations&lt;/div&gt; - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract&amp;#x2019;s transaction price is allocated to each distinct performance obligation in proportion to its standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. The Company&amp;#x2019;s various performance obligations and the timing or method of revenue recognition are discussed below.&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 sells its products to both distributors and end-users. Each unit of product delivered under a customer order represents a distinct and separate performance obligation, as the customer can benefit from each unit on its own or with other resources that are readily available to the customer, and each unit of product is separately identifiable from other products in the arrangement.&lt;/div&gt; &lt;div style=" font: 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 transaction price for the Company&amp;#x2019;s products is the invoiced amount. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone selling price; therefore, the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; need to allocate proceeds on a relative standalone selling price allocation between performance obligations. The Company applies the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;14&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; disclose information about remaining performance obligations that have original expected durations of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year or less. There are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; material obligations that extend beyond &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year.&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: 10 --&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;Revenue is recognized when transfer of control occurs as defined by the terms in the customer agreement. The Company immediately recognizes incidental items that are immaterial in the context of the contract. The Company has applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;16A&lt;/div&gt; and does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; assess if immaterial items are promised goods or services. The Company has also applied the practical expedient in paragraph &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;606&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;32&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;18&lt;/div&gt; regarding the adjustment of the promised amount of consideration for the effects of a significant financing component when the customer pays for that good or service within &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year or less, as the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have any significant financing components in its customer arrangements since payment is received at or shortly after the point of sale, generally &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;thirty&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ninety&lt;/div&gt; days.&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 estimates returns based on an analysis of historical experience if the right to return products is granted to its customers. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; record a return asset, as non-conforming products are generally &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; returned. The Company&amp;#x2019;s return policy does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; vary by geography. The customer has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; rotation or price protection rights, and the Company is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; under a warranty obligation.&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;Trade Receivables&lt;/div&gt; - Trade receivables include amounts invoiced and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company records an allowance for doubtful accounts to provide for the estimated amount of receivables that will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be collected. The allowance is based on a review of all outstanding amounts on an on-going basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considers a customer&amp;#x2019;s financial condition, credit history, and current economic conditions. Trade receivables are written off when deemed uncollectible and have been historically insignificant. Recoveries of trade receivables previously written off are recorded when received. Accounts are considered past due if payment is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; received according to agreed-upon terms.&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;Sales Commissions&lt;/div&gt; - Sales commissions paid to sales representatives are eligible for capitalization, as they are incremental costs that would &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have been incurred without entering into a specific sales arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical expedient provided by ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;340&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;40&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;25&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;4&lt;/div&gt; and recognize the incremental costs of obtaining contracts as an expense when incurred, as the amortization period of the assets that would have otherwise been recognized is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year or less. The Company records these costs as a selling expense.&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;Product Warranty&lt;/div&gt; - The Company offers warranties on various products and services. These warranties are assurance type warranties that are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; sold on a standalone basis; therefore, they are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; considered distinct performance obligations. The Company estimates the costs that &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be incurred under its warranties and records a liability in the amount of such costs at the time the revenue is recognized for the product sale.&lt;/div&gt; &lt;div style=" font: 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;International Revenue&lt;/div&gt; - The Company markets its products to numerous countries in North America, Europe, Latin America, Asia, and other parts of the world.

Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The guidance will be effective for the Company&amp;#x2019;s &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; quarter of fiscal year &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020.&lt;/div&gt; The Company is currently assessing the effect that ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;02&lt;/div&gt; will have on its consolidated financial statements but does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; expect it will have a material impact on its consolidated balance sheet.&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: 11 --&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-weight: inherit; font-style: normal;"&gt; February 2018, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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-weight: inherit; font-style: normal;"&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.

The proposal to approve the Share Increase Amendment was initially voted on and approved at the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting of Stockholders. However, because the description of the authority of brokers to vote on proposals without instruction in the proxy statement for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt; Annual Meeting of Stockholders could have created some uncertainty as to the effect of the vote obtained at last year&amp;#x2019;s meeting, and out of an abundance of caution, the Board requested that stockholders at the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Annual Meeting ratify the filing and effectiveness of the Certificate of Amendment to the Company&amp;#x2019;s Restated Certificate of Incorporation, which was filed with the Secretary of State of the State of Delaware on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 16, 2018, &lt;/div&gt;pursuant to Delaware law, in order to eliminate any uncertainty related to the effectiveness of the share increase amendment. Since the ratification proposal was approved by stockholders at the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Annual Meeting, the ratification was retroactive to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 16, 2018, &lt;/div&gt;the time of filing of the Share Increase Amendment with the Secretary of State of the State of Delaware.&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;At the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Annual Meeting held on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 18, 2019, &lt;/div&gt;the Company&amp;#x2019;s stockholders approved the Northern Technologies International Corporation &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Stock Incentive Plan (the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan), which replaced the Northern Technologies International Corporation Amended and Restated &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Stock Incentive Plan (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan). &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; new awards will be granted under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan, although the terms of the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan continue to govern awards outstanding under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan until exercised, expired, paid, or otherwise terminated or canceled. Subject to adjustment, the maximum number of shares of common stock authorized for issuance under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;800,000&lt;/div&gt; shares. &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; stock options or other equity awards have been granted under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt; Plan as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&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;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;During the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;nine&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2019, &lt;/div&gt;the Company granted stock options under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan to purchase an aggregate of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;141,768&lt;/div&gt; shares of its common stock to various employees and directors. The weighted average per share exercise price of the stock options is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$18.23,&lt;/div&gt; which was equal to the fair market value of the Company&amp;#x2019;s common stock on the date of grant.

This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> September 1, 2018, </div>the Company adopted ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div> for all customer contracts using the modified retrospective method. To determine revenue recognition for arrangements within the scope of ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606,</div> the Company performs the following <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">five</div> steps: (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">1</div>) identify the contracts with a customer; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2</div>) identify the performance obligations in the contract; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">3</div>) determine the transaction price; (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">4</div>) allocate the transaction price to the performance obligations in the contract; and (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">5</div>) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">five</div>-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to, or services it performs for, the customer.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <!-- Field: Page; Sequence: 9 -->   <!-- Field: /Page --> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"></div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The adoption of ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div> neither impacted the previously reported financial statements in any prior period nor did it result in a cumulative effect adjustment to retained earnings. Therefore, the adoption of the standard did <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> impact the Company&#x2019;s revenue recognition process. Generally, the Company&#x2019;s performance obligations are satisfied when the customers take possession of the products, which normally occurs at the shipping point or destination depending on the terms of the contracts. The Company&#x2019;s services are generally sold based upon quotes or contracts with customers that include a fixed or determinable price, and sales arrangements do <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> contain any significant financing component for its customers. The Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> recognize revenue related to product warranties, nor does the Company incur significant contract costs. Customer arrangements do <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> generate contract assets or liabilities.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Changes to the Company&#x2019;s significant accounting policies as a result of adopting ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div> are discussed below.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">Revenue Recognition</div> - Revenue is measured based on consideration specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including noncash consideration, consideration paid or payable to customers, and significant financing components. While most of the Company&#x2019;s revenue is contracted with customers through <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div>-time purchase orders and short-term contracts, the Company does have long-term arrangements with certain customers. Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Individually promised goods and services in a contract are considered a distinct performance obligation and accounted for separately if the customer can benefit from the individual good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement. When an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs are met. Costs of revenues consist primarily of direct labor, manufacturing overhead, materials, and components. The Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> incur significant upfront costs to obtain a contract. If costs to obtain a contract were to become material, the costs would be recorded as an asset and amortized to expense in a manner consistent with the related recognition of revenue.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company excludes government assessed and imposed taxes on revenue generating transactions that are invoiced to customers from revenue. The Company includes freight billed to customers in revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The timing of revenue recognition, billing, and cash collections results in accounts receivable on the balance sheet.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">Performance Obligations</div> - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract&#x2019;s transaction price is allocated to each distinct performance obligation in proportion to its standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. The Company&#x2019;s various performance obligations and the timing or method of revenue recognition are discussed below.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company sells its products to both distributors and end-users. Each unit of product delivered under a customer order represents a distinct and separate performance obligation, as the customer can benefit from each unit on its own or with other resources that are readily available to the customer, and each unit of product is separately identifiable from other products in the arrangement.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The transaction price for the Company&#x2019;s products is the invoiced amount. The Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> have variable consideration in the form of refunds, credits, rebates, price concessions, pricing incentives, or other items impacting transaction price. The purchase order pricing in arrangements with customers is deemed to approximate standalone selling price; therefore, the Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> need to allocate proceeds on a relative standalone selling price allocation between performance obligations. The Company applies the practical expedient in paragraph <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">10</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">50</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">14</div> and does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> disclose information about remaining performance obligations that have original expected durations of <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year or less. There are <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">no</div> material obligations that extend beyond <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <!-- Field: Page; Sequence: 10 -->   <!-- Field: /Page --> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"></div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Revenue is recognized when transfer of control occurs as defined by the terms in the customer agreement. The Company immediately recognizes incidental items that are immaterial in the context of the contract. The Company has applied the practical expedient in paragraph <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">10</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">25</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">16A</div> and does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> assess if immaterial items are promised goods or services. The Company has also applied the practical expedient in paragraph <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">606</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">10</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">32</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">18</div> regarding the adjustment of the promised amount of consideration for the effects of a significant financing component when the customer pays for that good or service within <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year or less, as the Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> have any significant financing components in its customer arrangements since payment is received at or shortly after the point of sale, generally <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">thirty</div> to <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">ninety</div> days.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company estimates returns based on an analysis of historical experience if the right to return products is granted to its customers. The Company does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> record a return asset, as non-conforming products are generally <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> returned. The Company&#x2019;s return policy does <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> vary by geography. The customer has <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">no</div> rotation or price protection rights, and the Company is <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> under a warranty obligation.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">Trade Receivables</div> - Trade receivables include amounts invoiced and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company records an allowance for doubtful accounts to provide for the estimated amount of receivables that will <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> be collected. The allowance is based on a review of all outstanding amounts on an on-going basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considers a customer&#x2019;s financial condition, credit history, and current economic conditions. Trade receivables are written off when deemed uncollectible and have been historically insignificant. Recoveries of trade receivables previously written off are recorded when received. Accounts are considered past due if payment is <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> received according to agreed-upon terms.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">Sales Commissions</div> - Sales commissions paid to sales representatives are eligible for capitalization, as they are incremental costs that would <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> have been incurred without entering into a specific sales arrangement and are recoverable through the expected margin on the transaction. The Company has elected to apply the practical expedient provided by ASC <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">340</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">40</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">25</div>-<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">4</div> and recognize the incremental costs of obtaining contracts as an expense when incurred, as the amortization period of the assets that would have otherwise been recognized is <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">one</div> year or less. The Company records these costs as a selling expense.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">Product Warranty</div> - The Company offers warranties on various products and services. These warranties are assurance type warranties that are <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> sold on a standalone basis; therefore, they are <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> considered distinct performance obligations. The Company estimates the costs that <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may </div>be incurred under its warranties and records a liability in the amount of such costs at the time the revenue is recognized for the product sale.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><div style="display: inline; font-style: italic;">International Revenue</div> - The Company markets its products to numerous countries in North America, Europe, Latin America, Asia, and other parts of the world.

Since the ratification proposal was approved by stockholders at the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2019</div> Annual Meeting, the ratification was retroactive to <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> January 16, 2018, </div>the time of filing of the Share Increase Amendment with the Secretary of State of the State of Delaware.</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</div> <div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">At the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2019</div> Annual Meeting held on <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> January 18, 2019, </div>the Company&#x2019;s stockholders approved the Northern Technologies International Corporation <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2019</div> Stock Incentive Plan (the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2019</div> Plan), which replaced the Northern Technologies International Corporation Amended and Restated <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2007</div> Stock Incentive Plan (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2007</div> Plan). <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">No</div> new awards will be granted under the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2007</div> Plan, although the terms of the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2007</div> Plan continue to govern awards outstanding under the <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2007</div> Plan until exercised, expired, paid, or otherwise terminated or canceled.
