<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In May 2014, the Financial Accounting Standards Board (FASB)
issued <i>Revenue from Contracts with Customers, Topic 606</i> (Accounting Standards Update (ASU) No. 2014-09), which provides
a framework for the recognition of revenue, with the objective that recognized revenues properly reflect amounts an entity is entitled
to receive in exchange for goods and services. This guidance, which includes additional disclosure requirements regarding revenue,
cash flows and obligations related to contracts with customers, was originally to be effective for the Company beginning in fiscal
year 2018. In July 2015, the FASB confirmed a one-year deferral of the effective date of the new revenue standard which also allows
early adoption as of the original effective date. The updated guidance will be effective for the Company&#8217;s first quarter
of 2019. The Company is currently evaluating the impact of adopting ASU 2014-09 on its consolidated financial statements, but currently
believes that the timeline established for implementation is attainable.</p>

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In July 2015, the FASB issued ASU No. 2015-11, &#8220;<i>Inventory</i>,&#8221;
which modifies the subsequent measurement of inventories recorded under a first-in-first-out or average cost method. Under the
new standard, such inventories are required to be measured at the lower of cost and net realizable value. The new standard is effective

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In November&nbsp;2015, FASB issued ASU 2015-17,&nbsp;<i>Income
Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes</i>,&nbsp;which requires that deferred tax assets and liabilities
be classified as noncurrent in a classified balance sheet. The amendment takes effect for public entities for fiscal years beginning
after December&nbsp;15, 2017, with early adoption available. The Company adopted ASU 2015-17 as of August 31, 2016; and there was
no material impact on its consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During February 2016, the FASB issued ASU No. 2016-02, &#8220;<i>Leases</i>.&#8221;
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 Company is currently assessing the effect that ASU No. 2016-02
will have on its consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In March 2016, the FASB issued ASU No. 2016-07, &#8220;<i>Investments
&#8211; Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting</i>.&#8221;
Among other things, the amendments in ASU 2016-07 eliminate the requirement that when an investment qualifies for use of the equity
method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment,
results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during
all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of
acquiring the additional interest in the investee to the current basis of the investor&#8217;s previously held interest and adopt
the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying
for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity
that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings
the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for
use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal
years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases
in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted.
The Company is currently assessing the impact that ASU 2016-07 will have on its consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In March 2016, the FASB issued ASU 2016-09, <i>Stock Compensation</i>,
which is intended to simplify several aspects of the accounting for share-based payment award transactions. The guidance will be
effective for the fiscal year beginning after December 15, 2016, including interim periods within that year. The Company is currently
assessing the impact that ASU 2016-09 will have on its consolidated financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In August 2016, the FASB issued ASU No. 2016-15, <i>&#8220;Statement
of Cash Flows, Classification of Certain Cash Receipts and Cash Payments</i>&#8221;&nbsp;&nbsp;ASU 2016-15 eliminates the diversity
in practice related to the classification of certain cash receipts and payments for debt prepayments or extinguishment costs, the
maturing of a zero coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance
settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization.
ASU 2016-15 designates the appropriate cash flow classification, including requirements to allocate certain components of these
cash receipts and payments among operating, investing and financing activities. The guidance is effective for fiscal years beginning
December 15, 2017. Early adoption is permitted. The Company is currently evaluating the effects of adopting ASU 2016-15 on its
consolidated financial statements, but the adoption is not expected to have a significant impact as of the filing of this report.</p>

venture agreements with its previous joint venture in China, Tianjin Zerust, began the process of liquidating the joint venture
entity, and commenced operations in China through a wholly-owned subsidiary, NTIC (Shanghai) Co. Ltd. on January 1, 2015. Effective
December 31, 2014, the Company&#8217;s investment in Tianjin Zerust was reported at carrying value based on the Company&#8217;s
decreased level of influence over the entity, and the Company has reclassified previously unrecognized gains on foreign currency
translation from accumulated other comprehensive income. Since it began the process of liquidating the joint venture entity on
December 31, 2014, the Company has not received any proceeds from the assets of Tianjin Zerust. In addition, the Company has not
received financial information or cooperation from its joint venture partner in determining the investment value. During the fourth
quarter of fiscal 2016, the Company obtained additional information regarding the financial position of the investment through
the legal proceedings that have been ongoing (See Note 13). These circumstances resulted in the Company concluding an indication
of impairment existed and that the fair value of the investment was $0 as of August 31, 2016 based on accounting principles generally
accepted in the United States of America. See Note 13 regarding ongoing litigation involving Tianjin Zerust.</p></div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Company has two stock-based compensation plans under which
stock options and other stock-based awards have been granted, the Northern Technologies International Corporation Amended and Restated
2007 Stock Incentive Plan and the Northern Technologies International Corporation Employee Stock Purchase Plan (the ESPP). The
Compensation Committee of the Board of Directors and the Board of Directors administer these plans.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The 2007 Plan provides for the grant of incentive stock options,
non-statutory stock options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses
to eligible recipients to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities
for equity participation in the Company, and to reward those individuals who contribute to the achievement of the Company&#8217;s
economic objectives. Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company&#8217;s
common stock are issuable under the 2007 Plan. Options granted under the 2007 Plan 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, 2017, only stock options and stock bonuses had been granted under the 2007
Plan.</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 maximum number of shares of common stock of the Company
available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month
offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the
fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount
rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory
for financial reporting purposes.</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 granted options to purchase an aggregate of 56,677
and 53,447 shares of its common stock during the nine months ended May 31, 2017 and 2016, respectively. The fair value of option
grants is determined at date of grant, using the Black-Scholes option pricing model with the assumptions listed below.&nbsp; The
Company recognized compensation expense of $293,748 and $325,576 during the nine months ended May 31, 2017 and 2016, respectively,
related to the options that vested during such time period. As of May 31, 2017, the total compensation cost for non-vested options
not yet recognized in the Company&#8217;s consolidated statements of operations was $337,316, net of estimated forfeitures. Stock-based
compensation expense of $97,916 is expected through the remainder of fiscal year 2017, and $159,600 and $79,800 is expected to
be recognized during fiscal 2018 and fiscal 2019, respectively, based on outstanding options as of May 31, 2017. Future option
grants will impact the compensation expense recognized. Stock-based compensation expense is included in general and administrative
expense on the consolidated statements of operations.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The fair value of each option grant is estimated on the grant
date using the Black-Scholes option-pricing model with the following assumptions and results for the grants:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On August 26, 2016, 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, 2017. For fiscal 2017 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 consider 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 Adjusted EBITOI for fiscal 2017 compared to a pre-established target Adjusted
EBITOI for fiscal 2017 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 are discretionary and may be paid to executive
officer participants in both cash and shares of the Company&#8217;s common stock, the exact amount and percentages will be 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 2017. There was $600,000 accrued for management bonuses for the nine months ended
May 31, 2017 compared to an accrual of $215,000 for management bonuses for the nine months ended May 31, 2016.</p>

the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec Corporation alleging,
among other things, that Cortec Corporation (Cortec) aided and abetted breaches of duties and contractual commitments owed to the Company
and NTI Asean related to the Company&rsquo;s joint venture in China, Tianjin Zerust.&nbsp; After fully litigating the case through discovery
and dispositive motion practice, on February 16, 2017, the Minnesota court denied both sides&rsquo; motions for summary judgment
and, <I>sua sponte</I>, dismissed without prejudice the Company&rsquo;s and NTI Asean&rsquo;s claims based on a non-exclusive forum-selection
clause contained in a 2005 settlement agreement between the Company and Cortec Corporation.&nbsp; While the Company had strong arguments to appeal
the Minnesota court&rsquo;s decision, an appeal would have meant a significant delay to the resolution of the dispute.&nbsp; On
April 21, 2017, the Company re-filed the lawsuit in the United States District Court for the Northern District of Ohio.&nbsp; On May 15,
2017, Cortec filed an answer and counterclaim.&nbsp; The counterclaim was promptly dismissed by the Court. Cortec has agreed that
all the discovery and information learned in the Minnesota case may be used in the Ohio case.&nbsp; The parties attended a Case
Management Conference (CMC) on June 21, 2017.&nbsp; The Court set a deadline of September 4, 2017 to complete discovery and set
the case for a jury trial on a two-week standby period beginning on September 18, 2017.</P>

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 technical 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), and
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">One of NTIC&#8217;s strategic initiatives is to expand into
and penetrate other markets for its ZERUST<sup>&#174;</sup> corrosion prevention solutions. 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">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 a long sales cycle, often including a one- to multi-year trial period with each customer
and a slow integration process thereafter.</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 participates in 20 active joint venture arrangements in
North America, Europe and Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory
to which it is assigned. While most of NTIC&#8217;s joint ventures exclusively sell rust and corrosion inhibiting products, some
of the joint ventures also sell NTIC&#8217;s Natur-Tec&#174; resin compounds. NTIC has historically funded its investments in joint
ventures with cash generated from operations.</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 receipt of funds from its joint ventures is dependent
upon fees for services that NTIC provides to its joint ventures, based primarily on the net sales of the individual joint ventures,
and NTIC&#8217;s receipt of dividend distributions from the joint ventures. The fees for services provided to joint ventures are
determined based on either a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC&#8217;s
joint venture in Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for such services. NTIC recognizes equity income
from its joint ventures based on the overall profitability of its joint ventures. Such profitability is subject to variability
from quarter to quarter which, in turn, subjects NTIC&#8217;s earnings to variability from quarter to quarter. The profits of NTIC&#8217;s
joint ventures 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, how much they should be 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 17.7% and 22.4%
during the three and nine months ended May 31, 2017, respectively, compared to the three and nine months ended May 31, 2016. These
increases were primarily a result of an increase in sales of ZERUST&#174; rust and corrosion inhibiting packaging products, sales
to joint ventures and sales of Natur-Tec&#174; products.</p>

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During the three and nine months ended May 31, 2017, 81.9% and
82.6% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of ZERUST&#174; products and services, which
increased 16.5% and 21.1% to $8,368,487 and $23,681,192 during the three and nine months ended May 31, 2017, respectively, compared
to $7,185,955 and $19,548,974 during the three and nine months ended May 31, 2016, respectively. These increases were due to higher
sales from existing customers for new and existing products as a result of increased demand. NTIC has expanded 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, 2017 included $1,287,789 of sales made to customers in the oil and gas industry compared to $1,229,426
for the nine months ended May 31, 2016. 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.
In addition, we believe demand for ZERUST&#174; products and services in the oil and gas industry may be dependent upon oil prices,
with low oil prices causing existing or potential customers to delay purchases and installations.</p>

the three and nine months ended May 31, 2017 compared to the three and nine months ended May 31, 2016, respectively. These increases
were primarily due to an increase in finished product sales in North America and finished product sales at NTIC&#8217;s majority

to $14,831,577 during the nine months ended May 31, 2017 compared to the nine months ended May 31, 2016. This increase was primarily
due: (i) an increase in operating expenses at Zerust Brazil and NTIC China of $170,000 and $140,000, respectively, consisting primarily
of selling and personnel expense associated with increased sales efforts in Brazil and China, respectively; (ii) an increase in

that it will spend between $2,700,000 and $2,900,000 in fiscal 2017 on research and development activities. This anticipated significant
decrease from fiscal 2016 is due to the transition of efforts from research and development to selling, general and administrative
areas, specifically as they relate to Natur-Tec<sup>&#174;</sup> products and the ZERUST<sup>&#174;</sup> oil and gas business since
most of the expenses related to these business units are no longer in the research and development phase of product development.</p>

for the nine months ended May 31, 2017 compared to $575,233 or $0.13 per diluted common share, for the nine months ended May 31,

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC anticipates that its quarterly net income or loss will
continue to remain subject to significant volatility primarily due to the financial performance of its subsidiaries and joint ventures

sales fluctuate more on a quarterly basis than the traditional ZERUST&#174; business. NTIC also anticipates that its operating results
during the next few quarters will be particularly volatile as a result of the changes in its Chinese operations.</p>

in North America, at NTIC China and an increase in sales of our Natur-Tec&#174; products. Net sales to joint ventures increased
13.3% and 7.8% to $862,136 and $2,115,511 during the three and nine months ended May 31, 2017, respectively, compared to the same

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During the three and nine months ended May 31, 2017, 81.9% and
82.6% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of ZERUST<sup>&#174;</sup> products and services,
which increased 16.5% and 21.1% to $8,368,487 and $23,681,192 during the three and nine months ended May 31, 2017, respectively,
compared to $7,185,955 and $19,548,974 during the three and nine months ended May 31, 2016, respectively. These increases were
due to increased demand from existing customers and the addition of new customers. NTIC has strategically focused its sales efforts
for ZERUST<sup>&#174;</sup> products and services on customers with sizeable corrosion problems in industry sectors that offer sizable
growth opportunities, including the oil and gas sector. Overall demand for ZERUST<sup>&#174;</sup> products and services depends
heavily on the overall health of the market segments to which NTIC sells its products, including the automotive, oil and gas, agriculture,
and mining markets in particular. In addition, we believe demand for ZERUST&#174; products and services in the oil and gas industry
may be dependent upon oil prices, with low oil prices causing existing or potential customers to delay purchases and installations.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC&#8217;s net sales to the oil and gas industry sector decreased
during the three months ended May 31, 2017 compared to the prior fiscal year period primarily as a result of volatility in that
sector and the timing of projects. NTIC&#8217;s net sales to the oil and gas industry sector increased during the nine months ended
May 31, 2017 compared to the prior fiscal year period primarily as a result of increased sales to India as a result of increased
demand. 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.</p>

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">During the three and nine months ended May 31, 2017, 18.1% and
17.4% of NTIC&#8217;s consolidated net sales, respectively, were derived from sales of Natur-Tec&#174; products, which increased
23.6% and 29.0% to $1,854,532 and $4,986,753 during the three and nine months ended May 31, 2017, respectively, compared to the
three and nine months ended May 31, 2016. Such increases were due to the addition of new customers in North America and India as
well as increased sales by existing distributors. Demand for Natur-Tec&#174; 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 Natur-Tec&#174; products, the timing of one or more orders can materially affect
NTIC&#8217;s quarterly sales of Natur-Tec&#174; products and the comparisons to prior fiscal year quarters.</p>

and 21.0% for the three and nine months ended May 31, 2017, respectively, compared to the three and nine months ended May 31, 2016.
These increases were primarily as a result of the corresponding increased sales levels. Cost of goods sold as a percentage of net
sales decreased to 66.3% during the three months ended May 31, 2017 compared to 66.5% during the three months ended May 31, 2016
and decreased to 67.2% during the nine months ended May 31, 2017 compared to 68.0% during the nine months ended May 31, 2016. These
decreases were primarily as a result of increased net sales and cost reductions realized on the raw materials associated with NTIC&#8217;s
ZERUST&#174; industrial products.</p>

2017, respectively, compared to equity in income of joint ventures of $1,664,464 and $3,600,884 during the three and nine months
ended May 31, 2016, respectively. These increases were primarily a result of improved sales and profitability at the joint ventures.

61.3% and 49.0% for the three and nine months ended May 31, 2017, respectively, compared to the same respective periods in fiscal

of selling and personnel expense associated with increased sales efforts, and the transition of expenses that were previously focused
on research and development efforts, but now relate to selling, specifically as they relate to Natur-Tec<sup>&#174;</sup> products
and the ZERUST<sup>&#174;</sup> oil and gas business, since most of the expenses related to these business units are no longer in
the research and development phase of product development. Selling expenses as a percentage of net sales increased to 23.8% and

the increase for the nine-month comparison was primarily due to: (i) the transition of expenses that were previously focused on

equivalents, 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
and any stock repurchases for at least the next 12 months. During the remainder of fiscal 2017, NTIC expects to continue to invest
in NTIC China, research and development and in marketing efforts and resources into the application of its corrosion prevention
technology into the oil and gas industry and its Natur-Tec&#174; bioplastics business. To take advantage of such new product and
market opportunities to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing
under its revolving line of credit or raising additional financing through the issuance of debt or equity securities. There is
no assurance that any financing transaction will be available on terms acceptable to NTIC or at all, or that any financing transaction
will not be dilutive to NTIC&#8217;s current stockholders.</p>

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC traditionally has used the cash generated from its operations,
distributions of earnings and fees for services provided to its joint ventures to fund NTIC&#8217;s new technology investments
and capital contributions to new and existing 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 it is not likely that there exists any exposure to debt by NTIC&#8217;s joint ventures
that could materially impact their respective operations and/or liquidity.</p>

activities during the nine months ended May 31, 2017 was $2,826,166, which resulted principally from dividends received from joint
ventures, net income, an increase in accounts payable and depreciation and amortization, partially offset by NTIC&#8217;s equity
in income from joint ventures and an increase in trade receivables. Net cash provided by operating activities during the nine months
ended May 31, 2016 was $3,053,297, which resulted principally from dividends received from NTIC&#8217;s joint ventures, net income,
the expensing of fair value of stock options vested, depreciation and amortization expense, and an increase in accounts payable,
partially offset by equity income from NTIC&#8217;s joint ventures, and a decrease in trade receivables and accrued liabilities.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">NTIC&#8217;s cash flows from operations are impacted by significant
changes in certain components of NTIC&#8217;s working capital, including inventory turnover and changes in receivables. NTIC considers
internal and external factors when assessing the use of its available working capital, specifically when determining inventory
levels and credit terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts
and customer requested payment terms, and 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 for trade receivables from its joint ventures are 90 days. 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 determination
is made. Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC&#8217;s typical
contractual terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services
provided to its joint ventures on an accrual basis, unless circumstances exist that make the collection of the balance uncertain
in which case the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled
on a case by case basis.</p>

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

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Because the functional currency of NTIC&#8217;s foreign operations
and investments in its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate
risk arising from transactions in the normal course of business. NTIC&#8217;s principal exchange rate exposure is with the Euro,
the Japanese yen, 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 of joint ventures
reflected in its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.</p>

information, but also forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and

telephone conferences and/or web casts open to the public, in press releases or reports, on NTIC&#8217;s Internet web site or otherwise.
All statements other than statements of historical facts included in this report or expressed by NTIC orally from time to time
that address activities, events or developments that NTIC expects, believes or anticipates will or may occur in the future are
forward-looking statements including, in particular, the statements about NTIC&#8217;s plans, objectives, strategies and prospects
regarding, among other things, NTIC&#8217;s financial condition, results of operations and business, the outcome of contingencies
such as legal proceedings and the effect of the liquidation of Tianjin Zerust and the operations of NTIC China. NTIC has identified
some of these forward-looking statements in this report with words like &#8220;believe,&#8221; &#8220;can,&#8221; &#8220;may,&#8221;

<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 of joint ventures
reflected in its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Some raw materials used in NTIC&#8217;s products are exposed
to commodity price changes. The primary commodity price exposures are with a variety of plastic resins.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">At the option of NTIC, outstanding advances under NTIC&#8217;s
$3,000,000 revolving line of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the
applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime
rate, and thus may subject NTIC to some market risk on interest rates. As of May 31, 2017, NTIC had no borrowings under the line
of credit.</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 maintains disclosure controls and procedures (as defined
in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to provide reasonable
assurance that information required to be disclosed by NTIC in the reports it files or submits under the Securities Exchange Act
of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange
Commission&#8217;s rules and forms and that such information is accumulated and communicated to NTIC&#8217;s management, including
NTIC&#8217;s principal executive officer and principal financial officer, or persons performing similar functions, as appropriate
to allow timely decisions regarding required disclosure. NTIC&#8217;s management evaluated, with the participation of its Chief
Executive Officer and its Chief Financial Officer, the effectiveness of the design and operation of NTIC&#8217;s disclosure controls
and procedures as of the end of the period covered in this report. Based on that evaluation, NTIC&#8217;s Chief Executive Officer
and Chief Financial Officer concluded that NTIC&#8217;s disclosure controls and procedures were effective as of the end of such
period to provide reasonable assurance that information required to be disclosed in the reports that NTIC files or submits under
the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On March 23, 2015, NTIC and NTI Asean LLC, a majority-owned
subsidiary of NTIC, filed a lawsuit in Tianjin No 1 Intermediate People&#8217;s Court against two individuals, Tao Meng and Xu
Hui, related to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to NTIC&#8217;s
former joint venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd. The lawsuit alleges, among other things, that Mr.
Tao Meng and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required
to go to Tianjin Zerust. At this point it is too early in the lawsuit to reasonably estimate the amount of any recovery to NTI
Asean.</p>

<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">On April 21, 2015, NTIC and NTI Asean initiated a lawsuit in
the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec Corporation alleging,
among other things, that Cortec Corporation (Cortec) aided and abetted breaches of duties and contractual commitments owed to NTIC
and NTI Asean related to NTIC&rsquo;s joint venture in China, Tianjin Zerust.&nbsp; After fully litigating the case through discovery
and dispositive motion practice, on February 16, 2017, the Minnesota court denied both sides&rsquo; motions for summary judgment
and, <I>sua sponte</I>, dismissed without prejudice NTIC&rsquo;s and NTI Asean&rsquo;s claims based on a non-exclusive forum-selection
clause contained in a 2005 settlement agreement between NTIC and Cortec Corporation.&nbsp; While NTIC had strong arguments to appeal
the Minnesota court&rsquo;s decision, an appeal would have meant a significant delay to the resolution of the dispute.&nbsp; On
April 21, 2017, NTIC re-filed the lawsuit in the United States District Court for the Northern District of Ohio.&nbsp; On May 15,
2017, Cortec filed an answer and counterclaim.&nbsp; The counterclaim was promptly dismissed by the Court. Cortec has agreed that
all the discovery and information learned in the Minnesota case may be used in the Ohio case.&nbsp; The parties attended a Case
Management Conference (CMC) on June 21, 2017.&nbsp; The Court set a deadline of September 4, 2017 to complete discovery and set
the case for a jury trial on a two-week standby period beginning on September 18, 2017.</P>

Each plan participant&amp;#x2019;s percentage of the overall bonus pool is based upon the number of plan participants, the individual&amp;#x2019;s annual base salary and the individual&amp;#x2019;s position and level of responsibility within the company.

The payment of bonuses under the plan are 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 the Company&amp;#x2019;s common stock, the exact amount and percentages will be 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;2017.&lt;/div&gt; There was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$600,000&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, 2017 &lt;/div&gt;compared to an accrual of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$215,000&lt;/div&gt; 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, 2016.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;!-- Field: /Page --&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;Two joint ventures (consisting of the Company&amp;#x2019;s joint ventures in Korea and India) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21.4%&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, 2017, &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 Korea, India and Thailand) accounted for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;55.8%&lt;/div&gt; of the Company&amp;#x2019;s trade joint venture receivables as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2016.&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;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 23, 2015, &lt;/div&gt;the Company and NTI Asean LLC (NTI Asean) filed a lawsuit in Tianjin &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;1&lt;/div&gt; Intermediate People&amp;#x2019;s Court against &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; individuals, Tao Meng and Xu Hui, related to breaches of duties and contractual commitments owed to NTI Asean under certain agreements related to the Company&amp;#x2019;s former joint venture in China, Tianjin Zerust Anti-Corrosion Technologies Ltd. (Tianjin Zerust). The lawsuit alleges, among other things, that Mr. Tao Meng and Xu Hui have engaged in self-dealing, usurped business opportunities, and received economic benefits that were required to go to Tianjin Zerust. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 31, 2017, &lt;/div&gt;the Company is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; able to reasonably estimate the amount of any recovery to NTI Asean, if any.&lt;/div&gt; &lt;div style=" font: 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&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; April 21, 2015, &lt;/div&gt;the Company and NTI Asean initiated a lawsuit in the District Court for the Second Judicial District, County of Ramsey, State of Minnesota against Cortec Corporation alleging, among other things, that Cortec Corporation (Cortec) aided and abetted breaches of duties and contractual commitments owed to the Company and NTI Asean related to the Company&amp;#x2019;s joint venture in China, Tianjin Zerust.&amp;nbsp; After fully litigating the case through discovery and dispositive motion practice, on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 16, 2017, &lt;/div&gt;the Minnesota court denied both sides&amp;#x2019; motions for summary judgment and, &lt;div style="display: inline; font-style: italic;"&gt;sua sponte&lt;/div&gt;, dismissed without prejudice the Company&amp;#x2019;s and NTI Asean&amp;#x2019;s claims based on a non-exclusive forum-selection clause contained in a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2005&lt;/div&gt; settlement agreement between the Company and Cortec Corporation.&amp;nbsp; While the Company had strong arguments to appeal the Minnesota court&amp;#x2019;s decision, an appeal would have meant a significant delay to the resolution of the dispute.&amp;nbsp; On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 21, 2017, &lt;/div&gt;the Company re-filed the lawsuit in the United States District Court for the Northern District of Ohio.&amp;nbsp; On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 15, 2017, &lt;/div&gt;Cortec filed an answer and counterclaim.&amp;nbsp; The counterclaim was promptly dismissed by the Court. Cortec has agreed that all the discovery and information learned in the Minnesota case &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be used in the Ohio case.&amp;nbsp; The parties attended a Case Management Conference (CMC) on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 21, 2017.&amp;nbsp; &lt;/div&gt;The Court set a deadline of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 4, 2017 &lt;/div&gt;to complete discovery and set the case for a jury trial on a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt;-week standby period beginning on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 18, 2017.&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 can 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;be 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, 2017, &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>

This guidance, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, was originally to be effective for the Company beginning in fiscal year &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018.&lt;/div&gt; In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 2015, &lt;/div&gt;the FASB confirmed a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-year deferral of the effective date of the new revenue standard which also allows early adoption as of the original effective date. The updated 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; The Company is currently evaluating the impact of adopting ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;09&lt;/div&gt; on its consolidated financial statements, but currently believes that the timeline established for implementation is attainable.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 2015, &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;2015&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;11,&lt;/div&gt; &amp;#x201c;&lt;div style="display: inline; font-style: italic;"&gt;Inventory&lt;/div&gt;,&amp;#x201d; which modifies the subsequent measurement of inventories recorded under a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt;-in-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt;-out or average cost method.

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; is effective for fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2018, &lt;/div&gt;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 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.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 2016, &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;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;07,&lt;/div&gt; &amp;#x201c;&lt;div style="display: inline; font-style: italic;"&gt;Investments &amp;#x2013; Equity Method and Joint Ventures (Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;323&lt;/div&gt;): Simplifying the Transition to the Equity Method of Accounting&lt;/div&gt;.&amp;#x201d; Among other things, the amendments in ASU &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;07&lt;/div&gt; eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor&amp;#x2019;s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2016. &lt;/div&gt;The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company is currently assessing the impact that ASU &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;07&lt;/div&gt; will have on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 2016, &lt;/div&gt;the FASB issued ASU &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;09,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Stock Compensation&lt;/div&gt;, which is intended to simplify several aspects of the accounting for share-based payment award transactions. The guidance will be effective for the fiscal year beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2016, &lt;/div&gt;including interim periods within that year. The Company is currently assessing the impact that ASU &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;09&lt;/div&gt; will have on its consolidated financial statements.&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 2016, &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;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;&amp;#x201c;Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments&lt;/div&gt;&amp;#x201d;&amp;nbsp;&amp;nbsp;ASU &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;15&lt;/div&gt; eliminates the diversity in practice related to the classification of certain cash receipts and payments for debt prepayments or extinguishment costs, the maturing of a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;zero&lt;/div&gt; coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization.

Subject to adjustment as provided in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan, up to a maximum of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;800,000&lt;/div&gt; shares of the Company&amp;#x2019;s common stock are issuable under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007&lt;/div&gt; Plan.

Since it began the process of liquidating the joint venture entity on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2014, &lt;/div&gt;the Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; received any proceeds from the assets of Tianjin Zerust. In addition, the Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; received financial information or cooperation from its joint venture partner in determining the investment value.

These circumstances resulted in the Company concluding an indication of impairment existed and that the fair value of the investment was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0&lt;/div&gt; as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 31, 2016 &lt;/div&gt;based on accounting principles generally accepted in the United States of America.

The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor&#x2019;s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">no</div> retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> December 15, 2016. </div>The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method.
