PART I

Overview

Northern Technologies International Corporation (NTIC) develops and markets proprietary environmentally beneficial products and services in over 60 countries either directly or via a network of subsidiaries, joint ventures, independent distributors and agents. NTIC’s primary business is corrosion prevention marketed mainly under the ZERUST® brand. NTIC has been selling its proprietary ZERUST® products and services to the automotive, electronics, electrical, mechanical, military and retail consumer markets for over 40 years, and, in recent years,more recently, has targeted and expanded into the oil and gas industry. NTIC also markets and sells a portfolio of biobased and certified compostable (fully biodegradable) polymer resinsresin compounds and finished products under the Natur-Tec® brand. These products are intended to reduce NTIC’s customers’ carbon footprint and provide environmentally sound waste disposal options.

NTIC’s ZERUST®ZERUST^® rust and corrosion inhibiting products include plastic and paper packaging, liquids, and coatings, rust removers, cleaners and cleaners, diffusers, and alsoas 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’s technical service consultants work directly with the end users of NTIC’s ZERUST®ZERUST^® rust and corrosion inhibiting products to analyze their specific needs and develop systems to meet their technicalperformance requirements. In North America, NTIC sells its ZERUST®ZERUST^® corrosion prevention solutions through a direct sales force as well as a network of independent distributors and agents.agents supported by a direct sales force. Internationally, NTIC sells its ZERUST®ZERUST^® 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’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 Prevenção de Corrosão 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).

One of NTIC’s strategic initiatives is to expand into and penetrate other markets for its ZERUST®ZERUST^® corrosion prevention solutions.technologies. Consequently, for the past several years, NTIC has focused significant sales and marketing efforts on the oil and gas industry, as thethat industry’s infrastructure that supports that industry is typically constructed usingconsists primarily of metals that are highly susceptible to corrosion. NTIC believes that its ZERUST®ZERUST^® corrosion prevention solutions will minimize maintenance downtime on critical oil and gas industry infrastructure, extend theits service life, of such infrastructure and reduce the risk of environmental pollution duecaused to corrosioncorrosion-related leaks.

NTIC markets and sells its ZERUST®ZERUST^® rust and corrosion prevention solutions to customers in the oil and gas industry acrossin several countries either directly, through its subsidiaries, or indirectly, through its joint venture partners and other strategic partners.third parties. The sale of ZERUST®ZERUST^® corrosion prevention solutions to customers in the oil and gas industry typically involves a very long sales cycle, often including a one- to multi-year trial periodperiods with each customer, and then followed by a slow integration process thereafter.

Natur-Tec®Natur-Tec^® biobased and compostable plastics are manufactured using NTIC’s patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec®Natur-Tec^® 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 resinsresin 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 collectionbranded apparel packaging bags and accessories, and various foodservice ware items such as disposable cutlery, packaging foamdrinking straws, food-handling gloves and coated paper products. In North America, NTIC markets its Natur-Tec® resinsNatur-Tec^® 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®Natur-Tec^® bioplastic products. Internationally, NTIC sells its Natur-Tec® resinsNatur-Tec^® resin compounds and finished products both directly and through its wholly-owned subsidiary in China, NTIC Shanghai, its majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India), and through distributors and certain joint ventures. In November 2014, NTIC entered into an agreement with NatureWorks LLC for joint marketing and sales of Ingeo® based packaging solutions to customers in India. With recent Indian government mandates banning use of non-biodegradable plastics in certain types of food and consumer packaging, NTIC expects the market in India for bioplastic packaging solutions to grow substantially.

Termination of Chinese Joint Venture

On January 2, 2015, NTIC announced that, effective as of December 31, 2014, it is selling its ZERUST® products and services in China through a wholly-owned subsidiary, NTIC (Shanghai) Co., Ltd. (NTIC China), and has terminated its joint venture agreements with Tianjin Zerust Anticorrosion Co., Ltd. (Tianjin Zerust).  NTIC and NTI Asean LLC have filed a lawsuit against Mr. Tao Meng, a Chinese national and the former joint venture entity’s other shareholder, and his spouse in the Chinese court of Tianjin, seeking, among other things, an orderly liquidation of Tianjin Zerust.NTIC’s Subsidiaries

NTIC indirectly has ownership interests in six operating subsidiaries in North America, South America, Europe and Asia. The following table sets forth a 30%list of NTIC’s operating subsidiaries as of November 9, 2018, the country in which the subsidiary is organized and NTIC’s ownership interestpercentage in Tianjin Zerust through its 60% owned holding company subsidiary, NTI Asean LLC.  Commencing during the second quartereach subsidiary:

The operating results of fiscal 2015,these subsidiaries are fully consolidated in NTIC’s consolidated financial statements include the financial results of NTIC China.  NTIC anticipates that it may take several quarters to transition many of the previous customers of Tianjin Zerust to NTIC China and no assurance can be provided that NTIC China will be able to achieve the net sales and income levels previously achieved by Tianjin Zerust.   For fiscal 2014, Tianjin Zerust had net sales of $15.9 million and net income of $1.3 million.  (The operating income of the joint venture before paying royalties in an aggregate amount of $4.2 million to all shareholders was over $5.5 million) NTIC’s indirect ownership of Tianjin Zerust is 30%.

During fiscal 2015, NTIC incurred approximately $1,640,000 in start-up expenses related either directly or indirectly to the establishment of NTIC China, the termination of the joint venture agreements with Tianjin Zerust, the pending litigation against Mr. Tao Meng and his spouse and Cortec Corporation, and the anticipated liquidation of Tianjin Zerust. These expenses are recorded as selling, general and administrative expenses and expenses incurred in support of joint ventures on the consolidated statements of operations.

NTIC expects its operating results may be volatile over the next few quarters as a result of NTIC’s Chinese operations.  In particular, because of the lack of financial and other information received from Tianjin Zerust, it is possible that receipt of future financial and other information from Tianjin Zerust may impact the realization of NTIC’s investment in and realization of a receivable from Tianjin Zerust. The last time NTIC received financial information from Tianjin Zerust was through November 2014.  NTIC, as of August 31, 2015, does not believe there are any triggering events that would require an impairment test.  NTIC’s current net investment is approximately $1.1 million, which is 60% of its investment in Tianjin Zerust, which was $1,883,668 as of August 31, 2015.  NTIC will continue to evaluate the realization of this asset on an ongoing basis and adjust if necessary.statements.

NTIC’s Joint Venture Network

NTIC participates in 19a total of 20 active joint venture arrangements inlocated across North America, Europe and Asia. Each of these joint ventures generally manufactures and markets products infor the geographic territory to which it is assigned. While most of NTIC’s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also sell NTIC’s Natur-Tec® resin compounds. NTIC has historically funded its investments in joint ventures with cash generated from operations.

The following table sets forth a list of NTIC’s operating joint ventures as of November 10, 2015,9, 2018, the country in which the joint venture is organized and NTIC’s ownership percentage in each joint venture:

Products

NTIC derives revenues directly and/or indirectly through its subsidiaries and joint ventures from the following two reportable business segments based on products sold, customer base and distribution center: ZERUST^® corrosion prevention solutions and Natur-Tec^® resin compounds and finished products.

ZERUST^®Corrosion Prevention Solutions. In fiscal 2015, 85.9%2018, 80.5% of NTIC’s consolidated net sales were derived from developing, manufacturing and marketing ZERUST^® rust and corrosion inhibiting products and services.  NTIC’s consolidated net sales in fiscal 20152018 included $26,042,909$41,374,305 in sales of ZERUST^® rust and corrosion inhibiting products and services, an increase of 9.2%26.2% over such sales in fiscal 2014.2017. Corrosion not only damages the appearance of metal products and components but also negatively impacts their mechanical performance.  This applies to the rusting of ferrous metals (iron and steel) and the deterioration by oxidation of nonferrous metals (aluminum, copper, brass, etc.).  NTIC’s ZERUST^® corrosion prevention solutions include plastic and paper packaging, powders, liquids, coatings, rust removers, cleaners, diffusers and engineered solutions for the oil and gas industry, as well as technical corrosion management and consulting services.

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

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

Liquids and Coatings.  NTIC’s corrosion prevention solutions include a line of metal surface treatment liquids and coatings, which are oil, water andor bio-solvent based, and are marketed under brand names including Axxatec^™, Axxanol^™ and Z-Maxx^™.  These liquids and coatings provide powerful corrosion protection in aggressive environments, such as salt air, andhigh humidity atand/or high temperatures.  Products are formulated for most metal types and protection levels. CustomersFor exceptionally harsh environments, customers may choose to use a combination of NTIC’s liquids and coatings with ZERUST^® plastic andand/or paper products to achieve robust corrosion protection during manufacturing, shipping and warehousing stages.

Rust Removers and Cleaners.  NTIC also sells rust removal and cleaning products designed to restore rusty parts to a usable condition by replacing labor-intensive, abrasive cleaners that damage surfaces and commonly fail to remove rust from complex metal surfaces like the teeth of small gears under the Axxaclean^™ brand name.

Diffusers.  NTIC’s corrosion prevention solutions include a line of corrosion inhibiting vapor diffusers, such as ZERUST^® ActivPak^®, ZERUST^® ICT^® Vapor Capsules, ZERUST^® ICT^® Plastabs^® and ZERUST^® ICT^® Cor-Tabs^®, ZERUST^® ICT^® Pipe Strip and ZERUST^® ICT^® Tube Strip.  These diffusers are designed to protect metals within enclosures, like switch gearboxes and electronic cabinets, or can be used as added protection to ZERUST^® packaging products.  Diffusers work by permeating the interior air of an enclosure with an invisible and odorless corrosion inhibiting vapor that protects nearby metal surfaces that are within a specific “radius of protection” for a period of one or two years depending on the model.  This invisible and dry protective layer revaporizes upon removal of the capsule from the enclosure, leaving all surfaces clean, dry, residue-free and corrosion-free. 

Z-CIS^® Technical Services.  As an on-going effort to help NTIC’s customers improve and control their processes in terms of corrosion management, NTIC markets and offers unique corrosion management and consulting services to target customers.  This ZERUST^® corrosion inhibition system (known as Z-CIS^®) utilizesleverages NTIC’s global experience in successfulnetwork to dispatch highly-trained technical service engineers to customer sites to solve complex corrosion management control.  Services and consulting are billed according to work done on the customer’s behalf to improve the customer’s internal and external corrosion control systems.problems.  Several major automotive companies and their automotive parts suppliers have used NTIC’s Z-CIS^® system.

ZERUST^®Corrosion Prevention Solutions Designed Specifically for the Oil and Gas Industry.  NTIC has developed proprietary engineered corrosion inhibiting solutions specifically for the mitigation of corrosion of the types of capital assets used in the petroleum and chemical process industries and has targeted the sale of these ZERUST^® corrosion solutions to potential customers in the oil and gas industry. NTIC’s consolidated net sales in fiscal 20152018 included $1,886,814$3,066,953 in sales made to customers in the oil and gas industry, an increase of 10.9%78.3% over such sales in fiscal 2014.2017. This increase is influenced by the increase in crude oil prices that have led to clients spending more money on maintenance projects than in fiscal 2017 as well as the deployment of ZERUST® Zerion products for the protection of new pipelines during construction. Projects in Europe and the Middle East are a small but strategically important part of the sales growth picture. The infrastructure that supports the oil and gas industry is predominantly constructed using metals that are highly susceptible to corrosion. The industrial environment at these facilities usually contains compounds, including sulfides and chlorides, which cause aggressive corrosion. This problem affects pipelines, petroleum storage tanks, spare parts in long-term storage, processing and other critical equipment. In addition to the costs associated with the replacement of parts and structures, maintenance and repairs, and product loss, there are significant economic losses associated with critical infrastructure being down for repair and maintenance. Furthermore, there are also considerable health, safety and environmental risks caused by corrosion that can greatly increase economic losses.  NTIC believes that its ZERUST®ZERUST^® oil and gas corrosion prevention solutions minimize maintenance downtime on critical oil and gas industry infrastructure, extend the life of such infrastructure and reduce the risk of environmental pollution due to leaks caused by corrosion. 

NTIC’s rust and corrosion inhibiting products for the oil and gas industry include ZERUST®ZERUST^® Flange Savers^{® ZERUST®} ZERUST^® ReCAST-R VCI Dispensers, Zerust ReCAST-SSB solutions and ZERUST®ZERUST^® chemicals, including Zerion chemicals,powders and gels, in addition to many of the traditional ZERUST®standard industrial ZERUST^® rust and corrosion inhibiting products previously described. 

ZERUST®ZERUST^® Flange Savers®Savers^® are specially designed covers that have been impregnated with a proprietary ZERUST®ZERUST^® inhibitor formulation to provide corrosion protection for flanges, valves and welded joints.  Oil and gas pipeline segments are connected by flanges and welded joints of varying sizes, designs and materials.  These connection points often corrode under aggressive industrial environments and harsh operating conditions, thereby causing costly maintenance, operational and safety problems.  ZERUST®ZERUST^® Flange Savers®Savers^® are available in various sizes to accommodate different pipe diameters, pressure ratings and international standards for pipeline valves and flanges. 

ZERUST®ZERUST^® ReCAST-R VCI Dispensers protect the interior surfaces of aboveground storage tank roofs by delivering proprietary inhibitor formulations into the vapor space between the surface of the product and the tank roof.  Certain grades of oil contain sulphur and emit corrosive acid gas vapors that destroy the internal surfaces of aboveground storage tank roofs and their support structures above the stored product.  Aggressive pitting and crevice corrosion create holes in tank roofs that cause unsafe operating conditions and environmental problems.  Internal tank coatings decrease surface corrosion but have proven to be ineffective in preventing dangerous pitting and crevice corrosion, especially in the interstitial spaces between the roof and support structures.  The ZERUST® ReCAST-R solution is designed to extend the service life of a single tank roof significantly by forming a protective inhibitor barrier which separates the corrosive environment from the metallic surface of the tank roof support structures and is designed to prevent corrosion in highly aggressive environments.  Each system is tailored to a customer’s requirements, depending upon specific environmental conditions, product stored, tank diameter and type of metal and can be applied on both new and existing tank roofs.

ZERUST®ZERUST^® ReCAST-SSB solutions protect the Soil Side Bottoms (SSB) of aboveground storage tanks through a variety of unique and highly effective delivery systems designed by the Zerust Oil & Gas team to deliver proprietary Zerion FVS corrosion inhibitor to tank bottom spaces that are susceptible to significant corrosion. Tank bottoms are typically made of steel plates which are in direct contact with the foundation surface that couldmay be concrete, sand/soil andor asphalt/bitumen. It is typically not possible to protect this underside surface with traditional coatings. Cathodic protection (CP) systems can only provide somepartial protection, but thesealso have significant limitations that cause failures well ahead of the expected service life of a tank. The ZERUST®ZERUST^® solutions provide effective protection even to areas that cannot be addressed with CP. This is an engineered solution where each system is tailored to a customer’s requirements depending on factors including the tank foundation design, specific environmental conditions, and tank diameter, etc.diameter.

During fiscal 2012, two of NTIC’s ZERUST® products designed for the oil and gas industry, ZERUST^® Flange Savers^® and the ZERUST^® ReCAST-R system, receivedMaterials Performance magazine’s “Readers’ Choice Corrosion Innovation of the Year” Awards.Materials Performance is published by NACE International, the world’s largest organization of professional engineers dedicated to the study, prevention and mitigation of corrosion.

Natur-Tec^®Resin Compounds and Finished ProductsProducts.. NTIC manufactures and sells a range of biobased and compostable (fully biodegradable) polymer resinsresin compounds and finished products under the Natur-Tec^® brand. NTIC’s consolidated net sales in fiscal 20152018 included $4,279,785$10,050,516 in sales of Natur-Tec^® resins and finished products, an increase of 43.6%48.2% over such sales in fiscal 2014.2017.  Market drivers such as volatile petroleum prices, reduced dependence on foreign oil, reduced carbon footprints, and environmentally responsible end-of-life solutions have increased interest in using sustainable, biobased and renewable plant-biomass resources for the manufacture of plastics and industrial products. Plastics that are fully biodegradable in composting or anaerobic digestor systems allow the safe and effective conversion of these plastics to carbon dioxide, water and fertilizer at the end of their service life.  Increased environmental and sustainability awareness at the corporate and consumer level, improved technical properties and product functionality, as well as recent foreign, state and local governmental regulations banning the use of traditional, petroleum-basedconventional plastics or mandating the use of certain biodegradable or compostable products, have also fueled this interest in biobased and biodegradable-compostable plastics.  The term “bio-plastics” encompasses a broad category of plastics that are either bio-based, which means derived from renewable resources such as corn or cellulosic/plant material or blends thereof, or are engineered to be fully compostable, or both. 

Resins.Resin Compounds.   Natur-Tec^® resinsresin compounds are produced by blending commercially available base resins, such as Ecoflex^® from BASF, Ingeo^® PLA from NatureWorks LLC, and/or Bionolle^® from Showa-Denko, with organic and inorganic fillers, and proprietary polymer modifiers and compatabilizers, using NTIC’s proprietary and patented ReX Process.  In this process, biodegradable polymers, natural polymers made from renewable, plant-biomass resources, and organic and inorganic materials are reactively blended in the presence of proprietary compatibilizers and polymer modifiers to produce biobased and/or compostable polymer resin formulations that exhibit unique and stable morphology.  Natur-Tec^® resin compounds are engineered for high performance, ease of processing and reduced cost compared to most other bio-plastic materials and can be processed by converters using conventional plastic manufacturing processes and equipment.

Natur-Tec^® resinsresin compounds are available in several grades tailored for a variety of applications, such as blown-film extrusion, extrusion coating and injection molding. 

Natur-Tec^® flexible film resinsresin compounds are fully compostable and meet the requirements of international standards for compostable plastics such as ASTM (American Society for Testing and Materials) D6400 (U.S.), EN 13432 (European standards for products and services by European Committee for Standardization) and ISO (International Organization for Standardization) 17088, and are certified as 100% compostable by organizations including the BPI (Biodegradable Products Institute) in the United States and VincotteTÜV Austria in Europe.  Natur-Tec^® film resinsresin compounds can be used to produce film for applications, such as bags, including compost bags, lawn and leaf bags, pet waste bags and carry-out bags, agricultural film and consumer and industrial packaging. Natur-Tec® film resin compounds are also used to produce bags and covers for branded apparel packaging and to manufacture specialty food service ware items, such as compostable drinking straws, and disposable food-handling gloves. 

The Natur-Tec^® compostable extrusion coating resin compounds are biobased and biodegradable and are designed to replace conventional plastic materials for extrusion coating applications.  Natur-Tec^® extrusion coating resin compounds are manufactured using sustainable and renewable resources, per the ASTM D6866 standard, which allows industry and consumers the opportunity to reduce or neutralize their carbon footprint and are designed to meet the requirements of international standards for compostable plastics, such as ASTM D6400.  Natur-Tec^® extrusion coating resinsresin compounds provide good adhesion to paper, an excellent print surface and good heat seal strength and the coating material is suitable for food contact applications including both hot and cold applications.  Natur-Tec^® extrusion coating resinsresin compounds can be used for coating paper and paperboards for the manufacture of disposable cups, plates and other food service ware items.

The Natur-Tec^® compostable injection molding resin compounds are biobased and compostable and are designed to replace conventional plastic materials for injection molded plastic applications.  Natur-Tec^® compostable injection molding resin compounds are manufactured using sustainable and renewable resources, per the ASTM D6866 standard and are designed to meet the requirements of international standards for compostable plastics, such as ASTM D6400 and EN 13432.  Natur-Tec^® compostable injection molding resin compounds can be used for injection molded plastic applications, such as cutlery, pens, hangers, containers and packaging.  Natur-Tec^® biobased injection molding resin compounds are made with at least 50%90% of biobased/renewable resource-based materials per the ASTM D6866 standard and are meant to enhance sustainability by replacing petroleum-based plastics.  Natur-Tec^® also produces biobased injection molding resin compounds that are not designed or intended to biodegrade but rather aid in sustainability by requiring less energy for production and by reducing dependence on petroleum as a raw material.  Natur-Tec^® biobased injection molding resin compounds exhibit the same properties as conventional plastic materials and can be used in applications, such as automotive components, consumer goods, electronics, medical products, furniture and packaging.

Finished Products.  Natur-Tec^® finished products include totally biodegradable and compostable trash bags, agricultural film and other single-use disposable products, such as compostable cutlery, as well as food and consumer goods packaging that are currently marketed under the Natur-Bag^® or Natur-Ware^® brands. 

The Natur-Bag^® product line offers 1215 different compostable trash bag sizes, from 3-gallon to 96-gallon.  The bags are available in various SKU configurations from retail packs that are sold to the consumer either through retail outlets or through online stores, and industrial case packs that are sold to commercial and industrial customers primarily through wholesalers and distributors.  The Natur-Bag^® products are manufactured from the Natur-Tec^® flexible film resin compounds and thus are fully biodegradable and compostable.

The Natur-Ware^® product line consists of biobased and compostable cutlery made from the Natur-Tec^® compostable injection molding resin compounds.  Natur-Ware®Natur-Ware^® cutlery can be composted along with food scraps in zero-waste programs. 

Both Natur-Bag®Natur-Bag^® and Natur-Ware®Natur-Ware^® products are fully certified compostable and carry the BPI Compostable logo in the United States and the VincotteTÜV Austria OK Compost logo in Europe. Furthermore, these products were also independently tested and approved for use in organic waste diversion systems by Cedar Grove, one of the largest compost operators in the United States.

Sales, Marketing and Distribution

ZERUST^®Corrosion Prevention Solutions. In the United States, NTIC markets its ZERUST^®rust and corrosion inhibiting products and services, including its products designed for the oil and gas industry, principally to industrial users in the automotive, electronics, electrical, mechanical, military, retail consumer and oil and gas markets by a direct sales force and through a network of independent distributors, manufacturer’s sales representatives and strategic partners. Prior to placing an order, NTIC’s technical service consultants work directly with the end users of NTIC’s ZERUST^®products to analyze their specific corrosion prevention needs and develop systems to meet their technicalperformance requirements.

Internationally, NTIC has entered into a series of joint ventures with foreign partners (either directly or through a holding company). NTIC receives fees for providing technical support, marketing assistance and other services to its joint ventures based primarily on the net sales of the individual joint ventures in accordance with the terms of the joint venture arrangements. Such services include consulting, legal, insurance, technical and marketing services. In China, NTIC sells its products and services through NTIC China. NTIC has a wholly-owned subsidiary to conduct its business in Mexico.

With respect to the sales and marketing of ZERUST^®rust and corrosion inhibiting products and services to the oil and gas industry, NTIC uses a combination of direct sales personnel, independent sales agents and its joint venture network.  In addition, in an attempt to penetrate the oil and gas industry within certain markets more quickly, NTIC has entered into certain sales and marketing agencyvarious agreements with specific organizations that have existing long term relationships with key oil and gas industry clients.  NTIC also engages in certain direct marketing activities to build its brand within the oil and gas industry, such as traditional advertising and direct mail campaigns and presence and participation at selected key trade shows and technical forums.  NTIC continues to believe the sale of its ZERUST^® corrosion prevention solutions to customers in the oil and gas industry will involve a long sales cycle,cycles, likely including a one- to multi-year trial periodperiods with each customer and a slow integration process thereafter.

Natur-Tec^®Resin Compounds and Finished Products. Products.  In the United States, NTIC markets its Natur-Tec^® resin compounds and finished products through a network of national and regional distributors and independent manufacturer’s sales representatives and threetwo NTIC direct sales employees as of August 31, 2015.2018. Target customers for Natur-Tec®Natur-Tec^® finished products include individual consumers andas well as commercial and institutional organizations such as corporations and government agencies, and educational organizations such as universities and school districts. NTIC is also targeting key national and regional retailers utilizing independent sales agents. Target customers for Natur-Tec^® resin compounds include film extruders and injection molders who would purchase Natur-Tec^® resin compounds to manufacture and sell their own finished biobased and compostable end products, such as film, bags and cutlery.

Internationally, NTIC uses NTINatur-Tec India, and its joint ventures and a network of international distributors to market its Natur-Tec^® resin compounds and finished products. In November 2014, NTIC entered into an agreement with NatureWorks LLC for joint marketing and sales of Ingeo^® based packaging solutions to customers in India. With Indian government mandates banning the use of non-biodegradable plastics in certain types of food and consumer packaging, NTIC expects the market in India for bioplastic packaging solutions to continue to grow substantially.

Competition

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

With respect to NTIC’s corrosion prevention solutions for use in the oil and gas industry, NTIC’s primary barrier to entry is a combination of conservatism, complacency, and confidence in old approaches, as well as the complexity of the buying organizations. Some of NTIC’s competitors with respect to its traditional ZERUST^® rust and corrosion inhibiting products also compete in the oil and gas industry. NTIC also faces competition from new suppliers who provide alternative approaches to corrosion prevention, some of which have a significant market presence and more years of experience and credibility in the oil and gas industry. Original equipment manufacturer (OEM) suppliers to the oil and gas industry present a new market vertical for NTIC’s traditional industrial ZERUST^® products.

Natur-Tec^®Resin Compounds and Finished Products.With respect to NTIC���sNTIC’s Natur-Tec^® resin compounds and finished products, NTIC competes with several established companies that have been producing and selling similar products for a significantly longer time period, and have significantly more sales, more extensive and effective distribution networks and better brand recognition than NTIC.  Most of these companies also have substantially more financial and other resources than NTIC.  NTIC competes on the basis of performance, brand awareness, distribution network, product availability, product offering, shelf life, place of manufacture and price.  Because of price competition, NTIC’s margins on its Natur-Tec^® resin compounds and finished products are lower than its margins on its ZERUST^® corrosion prevention solutions.  NTIC also could face supply constraints for the base resins used to manufacture NTIC’s Natur-Tec^® resin compounds and finished products since there are a limited number of suppliers of such base resins and limited capacity for their production.

Research and Development

NTIC’s research and development activities are directed at improving existing products, developing new products, reducing costs and improving quality assurance through improved testing of NTIC’s products. NTIC’s internal research and development activities are conducted at its facilities located in Circle Pines, Minnesota; Beachwood, Ohio; and Dresden, Germany under the direction of internationally known scientists and research institutes under exclusive contract to NTIC with respect to the subject of their respective research efforts. EXCOR has established a wholly-owned subsidiary, Excor Korrosionsforschung GmbH, to conduct research into new fields of corrosion inhibiting packaging and the applications engineering of such products in conjunction with NTIC’s domestic research and development operations. With respect to NTIC’s Natur-Tec^® resin compounds and finished products, Ramani Narayan, Ph.D., a current director of NTIC and Distinguished Professor in the Department of Chemical Engineering & Materials Science at Michigan State University, provides his expertise and technical support to NTIC.

NTIC spent $4,047,279 in fiscal 2015 in connection with its research and development activities, compared to $4,368,752 in fiscal 2014 and $3,815,515 in fiscal 2013. NTIC anticipates that it will spend between $4,000,000$3,200,000 and $4,500,000$3,600,000 in fiscal 20162019 on research and development activities. These amounts are net of reimbursements related to certain research and development contracts. Such reimbursements totaled $0, $45,788 and $274,728 in fiscal 2015, 2014 and 2013, respectively. Most of NTIC’s research and development contracts under which NTIC received reimbursements during fiscal 2014 were in connection with developing corrosion prevention solutions for the U.S. government in connection with developing future potential Natur-Tec^® products.

NTIC was awarded three National Science Foundation (NSF) awards -- one in June 2009 as a Phase I Small Business Technology Transfer (STTR) grant for $150,000 on advanced polylactide materials for biobased and biodegradable products, the second in September 2009 as a Phase I Small Business Innovation Research (SBIR) grant for an additional $150,000 on “Biobased coatings for corrosion protection” and a third in November 2011 as a Phase II SBIR grant of $500,000 for the development of advanced polylactide materials for biobased and biodegradable plastic products.  The Phase I projects were completed in June 2010 and have helped NTIC develop biobased technologies for new innovative applications in the ZERUST® and Natur-Tec® business areas. The Phase II project work was completed in fiscal 2015. The modified polylactic acid chemistries developed with this program helped NTIC to expand its product portfolio and commercialize novel bioplastics packaging solutions along with enhanced formulations for molded food service-ware.  The research and technology development was conducted in collaboration with Ramani Narayan, Ph.D., a current director of NTIC, and Michigan State University.

During fiscal 2010, NTIC was awarded funding from the U.S. Department of Defense for a Phase I Small Business Innovation Research contract worth $70,000 to develop non-plastic marine biodegradable waste bags for the U.S. Navy.  NTIC collaborated with the U.S. Army Natick labs and Michigan State University (MSU) on this project.  In November 2011, NTIC was awarded a Department of Defense Small Business Innovation Research Phase II grant of $500,000 for the ongoing development and commercialization of biobased and marine biodegradable non-plastic bags for the U.S. Navy.  The Phase II grant work continued during fiscal 2014 and was completed in April 2014 by supplying the NAVSUP office with marine biodegradable coated paper bags for evaluation. The NAVSUP office was unable to evaluate the bags due to lack of funding and later closed out the project due to cost and commercialization reasons. They identified this would currently be a niche product and would like to reevaluate once the technology was mature and commercialized in more markets. MSU is currently continuing research on the vegetable oil coating technology for usage in other applications.

Intellectual Property Rights

NTIC’s success depends and will continue to depend in part upon its ability to maintain patent and trademark protection for its products and processes, to preserve its proprietary information and trade secrets and to operate without infringing the proprietary rights of third parties.  NTIC’s policy is to attempt to protect its technology by, among other things, filing patent applications and trademark applications and vigorously preserving the trade secrets covering its technology and other intellectual property rights.

In 1979,1980, NTIC developed and patented the first polyolefin (plastic) based industrial corrosion inhibiting packing material in the world.  The U.S. patent granted under this patent application became the most important intellectual property right in NTIC’s history.  This patent expired in 2000.  NTIC has since filed for 12 letters of patents in the United States covering various corrosion inhibiting technologies, systems and applications, and now owns several patents in these areas.  These patents, as well as patent applications, have been extended to the countries of strategic relevance to NTIC including, but not limited to, the Patent Cooperation Treaty.such countries as Australia, Brazil, Canada, China, Europe, Japan, India, Korea, Mexico, Russia, and Taiwan.  In addition, EXCOR owns several patents in the area covering various corrosion inhibiting technologies and has also applied for new patents on proprietary new corrosion inhibiting technologies.  NTIC is also seeking additional patent protection covering various host materials into which its corrosion inhibiting additives and other protective features can be incorporated, proprietary new process technologies, and chemical formulations outside the area of corrosion protection.  NTIC owns several patents outside the area of corrosion protection both in the United States and in countries of strategic relevance to NTIC including but not limited to, the Patent Cooperation Treaty.above-noted countries.   

In addition to seeking patent protection, NTIC maintains an extensive portfolio of trademarks in countries where NTIC has a presence directly or through its subsidiaries and joint ventures.  NTIC continuously pursues new trademark applications of strategic interest worldwide.  NTIC owns the following U.S. registered trademarks: NTI^®NTI®, NTI & Globe Design, ZERUST^®ZERUST®, EXCOR^®EXCOR®, ICT^®ICT®, Z-CIS^®Z-CIS®, COR TAB^®TAB®, PLASTABS^®PLASTABS®, NATUR-TEC^®NATUR-TEC®, NATUR-TEC & Design^®Design®, NATUR-BAG^®NATUR-BAG® and NATUR-WARE^®NATUR-WARE®, ZERION®, AUTOFOG®, FLANGE SAVER® and ACTIVPAK®.  NTIC also has a registered trademark on the use of the Color Yellow with respect to corrosion inhibiting packaging.  Furthermore, NTI^®NTI®, ZERUST^®ZERUST®, The ZERUST People^®, EXCOR^®EXCOR®, the Color Yellow^®,Yellow® and NTI ASEAN^® and COR/SCI^®ASEAN®, as well as other marks have been registered in the European Union with several new applications pending.

NTIC requires its employees, consultants and advisors having access to its confidential information, including trade secrets, to execute confidentiality agreements upon commencement of their employment or consulting relationships with NTIC.  These agreements generally provide that all confidential information NTIC develops or makes known to the individual during the course of the individual’s employment or consulting relationship with NTIC must be kept confidential by the individual and not disclosed to any third parties.  NTIC also requires all of its employees and consultants who perform research and development for NTIC to execute agreements that generally provide that all inventions developed by these individuals during their employment by or service arrangement with NTIC will fall under NTIC’s proprietary intellectual property rights.

Manufacturing

NTIC’s ZERUST^®rust and corrosion inhibiting products are manufactured according to NTIC’s specifications primarily by selected independent sub-contractors under trade secrecy agreements and/or license agreements.  In addition, during fiscal 2015 and 2014, NTIC expanded its production capabilities and began to manufacturemanufactures select ZERUST^®rust and corrosion inhibiting products, consisting primarily of liquids and powders, in housein-house at its corporate headquarters location in Circle Pines, Minnesota.   

NTIC’s Natur-Tec^® resin compounds and finished products are produced at facilities in India, China, Malaysia and Malaysia.  Starting in fiscal 2014, NTIC made arrangements with a facility in California, as an alternative production source.USA. NTIC’s Natur-Tec^® resin compounds can be shipped to any manufacturing facility around the world where they then can be converted into finished products, such as a bag or piece of cutlery. NTIC’s Natur-Tec^® finished products are manufactured using NTIC’s Natur-Tec^® resin compounds by selected sub-contractors.

NTIC is ISO 9001 certified with respect to the manufacturing of its products.  NTIC believes that the process of ISO 9001 certification serves as an excellent total quality management tool, enabling NTIC to ensure consistency in the performance of its products.  In addition, because potential customers may prefer or require manufacturers to have achieved ISO certification, such ISO certifications may provide NTIC with certain competitive advantages.

Availability of Raw Materials

NTIC does not typically carry excess quantities of raw materials because of widespread availability for such materials from various suppliers. However, with respect to its Natur-Tec^® resin compounds and finished products, there are a limited number of suppliers of the base resins used to manufacture the resin compounds and finished products, and in the past NTIC has experienced some delaydelays in obtaining such base resins. In addition, a few raw materials and purchased parts used in NTIC’s rust and corrosion inhibiting products and Natur-Tec^® finished products are sourced from suppliers who currently serve as NTIC’s sole source of supply for these materials and parts. Although NTIC believes it can obtain these raw materials and parts from other sources of supply, an unexpected loss of supply over a short period of time may not allow NTIC time to replace these sources in the ordinary course of business.

Backlog

NTIC had an order backlog of $667,000$1,242,000 as of August 31, 2015,2018, compared to $995,000$668,000 as of August 31, 20142017, which was generally across all business units and $641,000 aswhich these sales will be realized during first quarter of August 31, 2013.fiscal 2019. These are orders that are held by NTIC pending release instructions from the customers to be used in just-in-time production. Customers generally place orders on an “as needed” basis and expect delivery within a relatively short period of time.

Governmental Regulation

The U.S. Food and Drug Administration (FDA) has indicated to NTIC that it has no objection to the use of ZERUST^®ICT^® packaging products in protecting metal food containers and processing equipment. In addition, the manufacture, sale and use of NTIC’s Natur-Tec^® resin compounds and finished products are subject to regulation in the United States by the FDA. The FDA’s regulations are concerned with substances used in food packaging materials. Thus, food and beverage containers are in compliance with FDA regulations if the components used in the food and beverage containers are approved by the FDA as indirect food additives for their intended uses and comply with the applicable FDA indirect food additive regulations or are generally recognized as safe for their intended uses and are of suitable purity for those intended uses. NTIC believes that its resinsresin compounds are in compliance with all FDA requirements and do not require further FDA approval prior to the sale of its products.

Item 1A. RISK FACTORS

The following are the most significant factors known to NTIC that could materially adversely affect its business, operating results or financial condition.

The termination of NTIC’s joint venture agreements with and the anticipated liquidation of Tianjin Zerust and the formation and establishment of NTIC China have had and could continue to have a material adverse effect on NTIC’s operating results.

Effective as of December 31, 2014, NTIC terminated its joint venture agreements with Tianjin Zerust, initiated the process to liquidate the joint venture entity and established a wholly-owned subsidiary to conduct business in China. Commencing during the second quarter of fiscal 2015, NTIC’s consolidated financial statements include the financial results of NTIC China. Tianjin Zerust was individually significant to NTIC’s consolidated assets and income. Accordingly, the termination of NTIC’s joint venture agreements with and the anticipated liquidation of Tianjin Zerust adversely affected NTIC’s operating results, including in particular, its equity in income, fee income for services provided to joint ventures and operating expenses, during fiscal 2015 since NTIC accounted for its investment in Tianjin Zerust in NTIC’s consolidated financial statements utilizing the equity method of accounting. Of the total equity in income from joint ventures of $5,936,565 during fiscal 2015 and $5,920,603 during fiscal 2014, NTIC had equity in income from joint ventures of $132,824 and $626,763 attributable to Tianjin Zerust, respectively. Of the total fee income for services provided to joint ventures of $5,715,491 during fiscal 2015 and $8,142,863 during fiscal 2014, $494,080 and $2,118,018 were attributable to Tianjin Zerust.

NTIC anticipates that it may take some time to transition the previous customers of Tianjin Zerust to NTIC China and no assurance can be provided that NTIC China will be able to achieve the net sales and income levels previously achieved by Tianjin Zerust. NTIC has incurred, and expects to continue to incur, significant operating expenses associated with NTIC China and the anticipated liquidation of Tianjin Zerust and expects that NTIC’s operating results may be volatile over the next several quarters. This is true especially since NTIC has commenced litigation against Mr. Tao Meng, Tianjin Zerust’s other shareholder, and his spouse in order to force the liquidation of Tianjin Zerust and has commenced litigation against Cortec Corporation alleging, among other things, that Cortec Corporation aided and abetted breaches of duties and contractual commitments owed to NTIC and NTI Asean related to Tianjin Zerust. During fiscal 2015, NTIC incurred approximately $1,642,258 in start-up expenses related either directly or indirectly to the establishment of NTIC China, the termination of the joint venture agreements with Tianjin Zerust, the pending litigation against Mr. Tao Meng and his spouse and Cortec Corporation, and the anticipated liquidation of Tianjin Zerust. The start-up expenses are inclusive of the losses incurred by the subsidiary of $1,042,258 during the same period.

NTIC expects its operating results may be volatile over the next few quarters as a result of NTIC’s Chinese operations.  In particular, because of the lack of financial and other information received from Tianjin Zerust, it is possible that receipt of future financial and other information from Tianjin Zerust may impact the realization of NTIC’s investment in and realization of a receivable from Tianjin Zerust. The last time NTIC received financial information from Tianjin Zerust was through November 2014.  NTIC, as of August 31, 2015, does not believe there are any triggering events that would require an impairment test.  NTIC’s current net investment is approximately $1.1 million, which is 60% of its investment in Tianjin Zerust, which was $1,883,668 as of August 31, 2015.  NTIC will continue to evaluate the realization of this asset on an ongoing basis and adjust if necessary.

NTIC’s pending litigation is expensive and may have an adverse effect on NTIC’s business and operating results.

During fiscal 2015, NTIC commenced litigation against Mr. Tao Meng, Tianjin Zerust’s other shareholder, and his spouse in order to force the liquidation of Tianjin Zerust and against Cortec Corporation alleging, among other things, that Cortec Corporation aided and abetted breaches of duties and contractual commitments owed to NTIC and NTI Asean related to Tianjin Zerust. Litigation is expensive and often uncertain. There is no assurance that NTIC will be successful in this litigation. In the meantime, it is likely that NTIC will incur significant expenses in pursuing the litigation. In addition, the pending litigation may have an adverse effect on NTIC’s business and operating results.

Any weakness in the global economy, and in particular in the United States, Europe and China, and in the automotive industry, may negatively impact NTIC’s business, operating results and financial condition.

The U.S. and world economies may suffer from uncertainty, volatility, disruption and other adverse conditions, and those conditions may adversely impact the business community and the financial markets. Adverse economic and financial market conditions may negatively affect NTIC’s customers and its markets, and thus negatively impact its business and operating results. For example, weak market conditions could extend the length of NTIC’s sales cycle and cause potential customers to delay, defer or decline to make purchases of NTIC’s products and services due to uncertainties surrounding the future performance of their businesses, limitations on their capital expenditures due to internal budget constraints, the inability to obtain financing in the capital markets, and the adverse effects of the economy on their business and financial condition. As a result, if economic and financial market conditions continue to be weak or even deteriorate, then NTIC’s business, financial condition and operating results, including its ability to grow and expand its business and operations, could be materially and adversely affected.

NTIC’s operating results are especially dependent upon the economic health of the global economy, includingeconomies in particular the United States, Europe and China. Of NTIC’s net sales in fiscal 2015, approximately $19.3 million were to customers in the United States and $1.1 million were to customers in China. In addition, approximately 63.5% of the $99 million in net sales of NTIC’s joint ventures during fiscal 2015 were to customers based in Europe. Accordingly, any weakness in the global economy, and in particular in the United States, Europe and China, may negatively impact NTIC’s business, operating results and financial condition.

The possibility that Greece and other EU member states may default on their debt obligations, the uncertainty regarding international and the European Union’s financial support programs, the possibility that EU member states may experience similar financial troubles and the austerity measures that have been implemented by Greece and certain other EU member states could negatively impact NTIC’s business, operating results and financial condition. During fiscal 2014, total net sales of NTIC’s joint ventures were adversely affected in part by the European economic slowdown, which NTIC believes adversely affected the net sales of NTIC’s European joint ventures, as well as certain of NTIC’s other non-European joint ventures. Although NTIC believes its fiscal 2015 financial results were not similarly affected, there is no assurance that its fiscal 2016 or future financial results will not be adversely affected. In addition, if the European sovereign debt crisis worsens, the value of the Euro and other European currencies could deteriorate, which could negatively impact the business, operating results and financial condition of NTIC and its joint ventures in light of the substantial operations of its joint ventures and the revenues its joint ventures derive from customers in the European Union. Apart from the European sovereign debt crisis, other global economies have experienced adverse economic conditions either as a result of the European sovereign debt crisis or otherwise that have affected all sectors of the economy.

During fiscal 2009, NTIC’s operating results were significantly adversely affected by worldwide economic conditions, particularly adverse conditions affecting the worldwide automobile industry at that time. Since a significant portion of NTIC’s ZERUST^® rust and corrosion inhibiting products and services are sold to customers in the automotive industry, adverse economic conditions affecting the automotive industry, again in particular, may result in another adverse effect on NTIC’s net sales and its other operating results. Accordingly, any weakness in the global economy, and in particular in the United States, Europe and China, and in the automotive industry, may negatively impact NTIC’s business, operating results and financial condition.

Changes to trade regulation, quotas, duties or tariffs, caused by the changing U.S. and geopolitical environments or otherwise, may negatively impact NTIC’s business, operating results and financial condition.

The U.S. government has taken actions or made proposals that are intended to address trade imbalances, specifically with China, among other countries, which include encouraging increased production in the United States. These actions and proposals have resulted or could result in increased customs duties and the renegotiation of some U.S. trade agreements. NTIC engages in sales outside of the United States. When custom duties are implemented or increased, it also may cause the trading partners of the United States to take actions with respect to U.S. imports in their respective countries. Any changes or potential changes in trade policies in the United States and the potential corresponding actions by other countries in which NTIC does business could adversely and materially affect NTIC’s business, results of operations or financial condition.

Global credit and financial markets in the past have experienced disruptions, including diminished liquidity and credit availability and rapid fluctuations in market valuations, which if they happen again, could negatively impact NTIC’s business, operating results and financial condition.

Any tightening of the credit and financial markets as a result of the European sovereign debt crisis or otherwise could negatively impact the ability of companies to borrow money from their existing lenders, obtain credit from other sources or raise financing to fund their operations. This could negatively impact the ability of NTIC’s customers and the customers of NTIC’s joint ventures to purchase NTIC’s products, suppliers’ ability to provide NTIC and its joint ventures with materials and components and the ability of NTIC and its joint ventures, distributors and sales representatives to finance operations, if needed, on commercially reasonable terms, or at all. Any or all of these events could negatively impact NTIC’s business, operating results and financial condition. Although NTIC maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers, distributors and joint ventures to make required payments and such losses historically have been within NTIC’s expectations and the provisions established, NTIC cannot guarantee that it will continue to experience the same loss rates that it has in the past, especially if there are weaknesses in the worldwide economy. A significant change in the liquidity or financial condition of NTIC’s customers, distributors or joint ventures could cause unfavorable trends in NTIC’s receivable collections and additional allowances may be required, which could adversely affect NTIC’s operating results. In addition, weaknesses in the worldwide economy may adversely impact the ability of suppliers to provide NTIC with materials and components, which could adversely affect NTIC’s business and operating results.results, and it is not known how the recent withdrawal by the United States from the Trans-Pacific Partnership trade agreement may also affect NTIC’s suppliers. NTIC is unable to predict the prospects for a global economic recovery, but the longer the duration of such adverse and uncertain economic conditions, the greater the risks NTIC faces in operating its business.

NTIC’s liquidity and financial position rely on the receipt of fees for services provided to its joint ventures and dividend distributions from its joint ventures. No assurance can be provided that NTIC will continue to receive such fees and dividend distributions in amounts NTIC historically has received or anticipates to receive.receiving.

NTIC conducts business, either directly or indirectly through several joint venture arrangements that operate in North America, Europe and Asia. Each of these joint ventures manufactures, markets and sells finished products in the geographic territory that it is assigned. NTIC’s receipt of funds as a result of sales by its joint ventures is dependent upon NTIC’s receipt of fees for services that NTIC provides to its joint ventures based primarily on the net sales of the individual joint ventures and NTIC’s receipt of dividend distributions from its joint ventures based on the profitability of its joint ventures. NTIC’s liquidity and financial position rely on NTIC’s receipt of fees for services that NTIC provides to its joint ventures and dividend distributions from its joint ventures. During fiscal 2015,2018, NTIC recognized $5,715,491$6,142,139 in fees and $2,983,338$3,697,503 in dividend distributions from its joint ventures. Because NTIC owns 50% or less of each of its joint venture entities, NTIC does not control the decisions of these entities regarding whether to pay dividends and, if paid, how much they should be in any given year. Thus, NTIC cannot guarantee that any of its joint ventures will pay dividends in any given year. The failure of NTIC’s joint ventures to declare dividends or the failure of NTIC to receive fees for services provided to joint ventures in amounts typically expected by NTIC could adversely affect NTIC’s liquidity and financial position.

Since a significant portion of NTIC’s earnings results from NTIC’s equity income from joint ventures and since NTIC’s equity income from joint ventures varies from quarter to quarter, NTIC’s earnings are subject to quarterly fluctuations.

A significant portion of NTIC’s earnings results from NTIC’s equity income from its joint ventures. NTIC’s equity in income from joint ventures consists of NTIC’s share of equity in income from its joint ventures based on the overall profitability of the joint ventures. Such profitability varies from quarter to quarter. Since NTIC’s management typically receives quarterly joint venture financial information after the completion of each fiscal quarter, it is impossible for NTIC’s management to cut costs and expenses to make up for any unanticipated shortfall in NTIC’s equity income from joint ventures. Accordingly, the variability in NTIC’s equity income from joint ventures, in turn, subjects NTIC’s earnings to quarterly fluctuations.

Out of NTIC’s joint ventures, NTIC’s joint venture in Germany is the most significant in terms of assets and income to NTIC. If sales of NTIC’s products and services by this joint venture were to decline significantly or if NTIC’s relationships with this joint venture were to deteriorate significantly, NTIC’s operating results likely would be adversely affected.

NTIC considers its joint venture in Germany EXCOR,(EXCOR) to be individually significant to NTIC’s consolidated assets and income;income, and therefore, provides certain additional information regarding this joint venture entityEXCOR in the notes to NTIC’s consolidated financial statements and in certain sections of this report. Of the total equity in income from joint ventures of $5,936,565$7,527,383 during fiscal 2015,2018, NTIC had equity in income from joint ventures of $4,091,608$5,549,765 attributable to EXCOR. Of the total fee income for services provided to joint ventures of $5,715,491$6,142,139 during fiscal 2015,2018, fees of $873,400 were$900,316 was attributable to EXCOR. Accordingly, if sales of NTIC’s products and services by this joint venture were to decline significantly or if NTIC’s relationships with this joint venture or joint venture partner were to deteriorate significantly such that the joint venture isit terminated or were not motivated to sell NTIC’s products and services, NTIC’s operating results likely would be adversely affected.

In addition, pursuant to Rule 3-09 of Regulation S-X, NTIC intends to file an amendment to this report to include the audited financial statements and related notes of EXCOR.

NTIC’s international business, which is conducted primarily through its subsidiaries and joint ventures, requires management attention and financial resources and exposes NTIC to difficulties and risks presented by international economic, political, legal, accounting and business factors.

NTIC sells products and services directly, through its wholly-owned subsidiary, NTIC China, itsand majority-owned subsidiaries, Zerust Brazil and Natur-Tec India, and its majority-owned holding company subsidiary, NTI Asean, and indirectly via a network of joint ventures, independent distributors, manufacturer’s sales representatives and agents in over 60 countries, including countries in North America, South America, Europe, Asia and the Middle East. One of NTIC’s strategic objectives is the continued expansion of its international operations. The expansion of NTIC’s existing international operations and entry into additional international markets requirerequires management attention and financial resources.

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

Several factors, including implications of withdrawal by the U.S. from, or revision to, international trade agreements, foreign policy changes between the U.S. and other countries, weakened international economic conditions or the impact of sovereign debt defaults by certain European countries, could adversely affect our international net sales. Additionally, the expansion of our existing international operations and entry into additional international markets require significant management attention and financial resources.  Many of the countries in which NTIC sells its products directly or indirectly through NTIC China, Zerust Brazil, Natur-Tec India, Zerust Mexico, NTI Asean, its joint ventures, distributors, representatives and agents are, to some degree, subject to political, economic and/or social instability. NTIC’s international operations expose NTIC and its joint venture partners, distributors, representatives and agents to risks inherent in operating in foreign jurisdictions. These risks include:

Furthermore, in June 2016, the United Kingdom held a referendum in which voters approved an exit from the European Union, commonly referred to as “Brexit.” As a result of the referendum, negotiations have commenced to determine the future terms of the United Kingdom’s relationship with the European Union, including the terms of trade between the United Kingdom and the European Union either during a transitional period or more permanently. Although it is unknown what those terms will be, it is possible that there will be greater restrictions on the movement of goods and people between the United Kingdom and European Union countries and increased regulatory complexities, which could affect NTIC’s ability to sell its products in certain European Union countries. Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the United Kingdom determines which European Union laws to replace or replicate. Brexit could adversely affect European and worldwide economic and market conditions and could contribute to instability in global financial and foreign exchange markets, including volatility in the value of the British pound and Euro. In addition, other European countries may seek to conduct referenda with respect to continuing membership with the European Union. NTIC does not know to what extent these changes will impact its business. Any of these effects of Brexit, and others that NTIC cannot anticipate, could adversely affect its business, operations and financial results.

The operations of NTIC China may be adversely affected by China’s evolving economic, political and social conditions.

The results of operations and future prospects of NTIC China may be adversely affected by, among other things, changes in China’s political, economic and social conditions, changes in the relationship between China and its western trade partners, changes in policies of the Chinese government, changes in laws and regulations or in the interpretation of existing laws and regulations, changes in foreign exchange regulations, measures that may be introduced to control inflation, such as interest rate increases, and changes in the rates of methods of taxation. In addition, changes in demand could result from increased competition with local Chinese manufacturers who have cost advantages or who may be preferred suppliers for Chinese end users. Also, Chinese commercial laws, regulations and interpretations applicable to non-Chinese owned market participants, such as NTIC China, are continually changing. These laws, regulations and interpretations could impose restrictions on NTIC’s and NTIC China’s ownership or operations or NTIC’s interests in China and could adversely affect NTIC’s business, results of operations or financial condition.

Intellectual property rights are difficult to enforce in China, which could harm NTIC’s business, results of operations or financial condition.

Chinese commercial law is relatively undeveloped compared with the commercial law in many of NTIC’s other major markets and limited protection of intellectual property is available in China as a practical matter. Although NTIC takes precautions in the operation of NTIC China to protect NTIC’s intellectual property, any local manufacturer of products that NTIC undertakes in China could subject NTIC to an increased risk that unauthorized parties will be able to copy or otherwise obtain or use NTIC’s intellectual property, which could harm NTIC’s business. NTIC may also have limited legal recourse in the event it encounters patent or trademark infringers, which could adversely affect NTIC’s business, results of operations or financial condition.

Uncertainties with respect to the Chinese legal system may adversely affect the operations of NTIC China.

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

Failure to comply with the U.S. Foreign Corrupt Practices Act could subject NTIC to, among other things, penalties and legal expenses that could harm its reputation and have a material adverse effect on its business, financial condition and results of operations.

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

If NTIC’s employees, joint ventures, distributors, third-party sales representatives or other agents are found to have engaged in such practices, NTIC could suffer severe penalties, including criminal and civil penalties, disgorgement and other remedial measures, including further changes or enhancements to its procedures, policies and controls, as well as potential personnel changes and disciplinary actions. The Securities and Exchange Commission has increased its enforcement of the FCPA during the past several years. Although NTIC does not believe it is currently a target in any such enforcement action, any investigation of any potential violations of the FCPA or other anticorruption laws by U.S. or foreign authorities also could have an adverse impact on NTIC’s business, financial condition and results of operations.

Certain private and foreign companies, including some of NTIC’s competitors, are not subject to prohibitions as strict as those under the FCPA or, even if subjected to strict prohibitions, such prohibitions may be laxly enforced in practice. If NTIC’s competitors engage in corruption, extortion, bribery, pay-offs, theft or other fraudulent practices, they may receive preferential treatment from personnel of some companies or from government officials, giving NTIC’s competitors an advantage in securing business and which would put NTIC at a disadvantage.

Fluctuations in foreign currency exchange rates could result in declines in NTIC’s earnings and changes in NTIC’s foreign currency translation adjustments.

Because the functional currency of NTIC’s foreign operations is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from transactions in the normal course of business. NTIC’s principal exchange rate exposure is with the Euro, the Japanese yen,Yen, Indian Rupee, Chinese Renminbi, South Korean wonWon and the English poundPound against the U.S. dollar. NTIC’s fees for services provided to its 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’s earnings. Any changes in foreign currency exchange rates would be reflected as a foreign currency translation adjustment and would not change NTIC’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.

Economic uncertainty in developing markets could adversely affect ourNTIC’s revenue and earnings.

NTIC conducts business, or is contemplating expansion, in developing markets with economies that tend to be more volatile than those in the United States and Western Europe. The risk of doing business in developing markets such as China, Brazil, India, Russia, the United Arab Emirates, Mexico and other economically volatile areas could adversely affect NTIC’s operations and earnings. Such risks include the financial instability among customers in these regions, political instability, fraud or corruption and other non-economic factors such as irregular trade flows that need to be managed successfully with the help of the local governments. In addition, commercial laws in some developing countries can be vague, inconsistently administered and retroactively applied. If NTIC is deemed not to be in compliance with applicable laws in developing countries where NTIC conducts business, its prospects and business in those countries could be harmed, which could then have a material adverse impact on NTIC’s operating results and financial position. NTIC’s failure to successfully manage economic, political and other risks relating to doing business in developing countries and economically and politically volatile areas could adversely affect its business.

NTIC faces intense competition in almost all of its product lines, including from competitors that have substantially greater resources than NTIC does. No assurance can be provided that NTIC will be able to compete effectively, which would harm its business and operating results.

NTIC’s products are sold in intense competitive markets throughout the world. This intense competition could result in pricing pressures, lower sales, reduced margins and lower market share. The principal competitive factors in NTIC’s corrosion prevention solutions markets are pricing, product innovation, quality and reliability, product support, customer service and reputation. Additional competitive factors present in NTIC’s bioplastics business are brand awareness, distribution network, product availability, product offering, shelf life and place of manufacture. NTIC often competes with numerous manufacturers, many of which have substantially greater financial, marketing, and other resources than NTIC. As a result, they may be able to adapt more quickly than NTIC to new or emerging technologies, industry trends, and changes in customer requirements, or to devote greater resources to the promotion and sale of their products than NTIC. In addition, competition could increase if new companies enter the markets in which NTIC competes, especially when the barriers to entry are low, which may be true with respect to NTIC’s rust and corrosion prevention business, or if existing competitors expand their product lines or intensify efforts within existing product lines. NTIC’s current products, products under development and its ability to develop new and improved products may be insufficient to enable NTIC to compete effectively with its competitors. No assurance can be provided that NTIC will be able to compete effectively, which would harm its business and operating results. In particular, NTIC has experienced more intense competition with respect to many of its traditional ZERUST^® rust and corrosion inhibiting products and services, which havehas led to decreased pricing and smaller margins for NTIC. Recently, NTIC has experienced lower margins on its contracts with Chinese automotive customers. NTIC anticipates that such intense competition likely will continue and that new competitors may emerge, including plastic extrusion companies, which would continue to adversely affect NTIC’s operating results.

NTIC’s ZERUST^® rust and corrosion inhibiting products and services generate a significant portion of NTIC’s net sales and the net sales of NTIC’s joint ventures. Accordingly, if sales of these products and services were to decline, NTIC’s operating results would be adversely affected.

NTIC’s ZERUST^® rust and corrosion inhibiting products and services generate a significant portion of NTIC’s net sales and the net sales of NTIC’s joint ventures. During fiscal 2015, 85.9%2018, 80.5% of NTIC’s consolidated net sales were derived from sales of ZERUST^® rust and corrosion inhibiting products and services. While the net sales of NTIC’s joint ventures are not included in NTIC’s net sales on NTIC’s consolidated financial statements, NTIC’s receipt of fees for services that NTIC provides to its joint ventures and NTIC’s receipt of dividend distributions from its joint ventures is based primarily on the revenues and profitability of the joint ventures. Accordingly, if sales of these products and services were to decline due to increased competition, the introduction of a new disruptive technology or otherwise, NTIC’s operating results would be adversely affected.

If NTIC is unable to continue to enhance its existing products and develop and market new products that respond to customer needs and achieve market acceptance, NTIC may experience a decrease in demand for its products, and its business could suffer.

One of NTIC’s strategies is to enhance its existing products and develop and market new products that respond to customer needs. NTIC may not be able to compete effectively with its competitors unless NTIC can keep up with existing or new products or alternative technologies in the markets in which it competes. Product development requires significant research and development, financial and other resources. Although in the past NTIC has implemented lean manufacturing and other productivity improvement initiatives to provide investment funding for new products, no assurance can be provided that NTIC will be able to continue to do so in the future. Product improvements and new product introductions also require significant planning, design, development and testing at the technological, product, and manufacturing process levels and NTIC may not be able to timely develop product improvements or new products. NTIC’s competitors’ new products may beat NTIC’s products to market, may be more effective or less expensive than NTIC’s products or render NTIC’s products obsolete. Any new products that NTIC may develop may not receive market acceptance or otherwise generate any meaningful net sales or profits for NTIC relative to its expectations, based on, among other things, existing and anticipated investments in manufacturing capacity and commitments to fund advertising, marketing, promotional programs, and research and development.

NTIC has invested and intends to continue to invest additional research and development and marketing efforts and resources into the application of its corrosion prevention solutions into the oil and gas industry and the continued launch of its Natur-Tec^® resin compounds and finished products. No assurance can be provided, however, that NTIC’s investments in these new markets and products will be successful and result in additional revenue to NTIC.

In an effort to increase net sales, NTIC has expanded the marketing of its corrosion prevention solutions into the oil and gas industry and its Natur-Tec^® resin compounds and finished products. The majority of NTIC’s research and development expense in fiscal 2015 was spent in connection with research and development activities related to these two strategic initiatives. NTIC expects to continue to invest additional research and development and marketing efforts and resources into these strategic initiatives. No assurance can be provided, however, that such strategic initiatives will be successful or that NTIC will be successful in obtaining additional revenue as a result of them. The introduction of new products into new markets takes significant resources and there can be no assurance that NTIC is dedicating a sufficient amount of resources to ensure the success of these strategic initiatives. The sale of NTIC’s ZERUST^® rust and corrosion inhibiting products and services into the oil and gas industry, in particular, typically involves a long sales cycle, often including a one- to multi-year trial period with each customer and a slow integration process thereafter. This long sales cycle may cause NTIC’s management, stockholders and investors to lose faith in the business opportunities for NTIC’s ZERUST^® rust and corrosion inhibiting products and services in the oil and gas industry.

The expansion of NTIC’s corrosion prevention solutions into the oil and gas industry and the continued launch of NTIC’s Natur-Tec^® resin compounds and finished products may require additional capital in the future, which may not be available or may be available only on unfavorable terms. In addition, any equity financings may be dilutive to NTIC’s stockholders.

The expansion of NTIC’s corrosion prevention solutions into the oil and gas industry and the continued launch of NTIC’s Natur-Tec^® resin compounds and finished products will continue to require significant resources during fiscal 20162019 and beyond. To the extent that NTIC’s existing capital, including amounts available under its revolving line of credit, is insufficient to meet these requirements, NTIC may raise additional capital through financings or additional borrowings. Any equity or debt financing, if available at all, may be on terms that are not favorable to NTIC and any equity financings could result in dilution to NTIC’s stockholders.

NTIC’s strategy of expanding its corrosion prevention solutions into the oil and gas industry and continuing its launch of its Natur-Tec^® bioplastics resin compounds and finished products is risky and may not prove to be successful, which could harm NTIC’s operating results and financial condition.

NTIC’s strategy of expanding its corrosion prevention solutions into the oil and gas industry and continuing its launch of its Natur-Tec^® bioplastics resin compounds and finished products, either directly or indirectly through joint ventures and independent distributors and agents, is risky and subject to all of the risks inherent in the establishment of a new business enterprise, including:

NTIC relies on others for its production and any interruptions of these arrangements could disrupt NTIC’s ability to fill its customers’ orders.

NTIC utilizes contract manufacturers for a significant portion of its production requirements. The majority of NTIC’s manufacturing is conducted in the United States by contract manufacturers that also perform services for numerous other companies. NTIC does not have a guaranteed level of production capacity with any of its contract manufacturers. Qualifying new contract manufacturers is time consuming and might result in unforeseen manufacturing and operations problems. The loss of NTIC’s relationships with its contract manufacturers or their inability to conduct their manufacturing and assembly services for NTIC as anticipated in terms of capacity, cost, quality and timeliness could adversely affect NTIC’s ability to fill customer orders in accordance with required delivery, quality, and performance requirements, and thus adversely affect NTIC’s net sales and other operating results.

NTIC’s dependence on manufacturing and logistical services provided by contractors could give rise to product defect or warranty liability.

NTIC uses third party manufacturers to produce the majority of its products. In addition, NTIC relies upon certain contractors for logistical services. Although NTIC’s arrangements with its contract manufacturers and contractors may contain provisions for warranty expense reimbursement, NTIC may remain responsible to its customers for warranty service in the event of product defects and could experience an unanticipated product defect or warranty liability. In addition, products defects could harm NTIC’s reputation amongst its customers.

NTIC’s dependence on key suppliers puts NTIC at risk of interruptions in the availability of its products, which could reduce its net sales and adversely affect its operating results and harm its reputation.

NTIC relies on suppliers for certain raw materials and components used in its products. For reasons of quality assurance, cost effectiveness or availability, NTIC procures certain raw materials and components from sole or limited source suppliers. NTIC generally acquires such raw materials and components through purchase orders placed in the ordinary course of business, and as a result, NTIC does not have a significant inventory of these materials and components and does not have any guaranteed or contractual supply arrangements with many of these suppliers for these materials and components. NTIC’s dependence on third-party suppliers involves several risks, including limited control over pricing, availability, quality and delivery schedules, as well as manufacturing yields and costs. Suppliers of such raw materials and components may decide, or be required, for reasons beyond NTIC’s control to cease supplying such raw materials and components to NTIC or to raise their prices.

Shortages of raw materials, quality control problems, production capacity constraints or delays by suppliers could negatively affect NTIC’s ability to meet its production obligations and result in increased prices for affected parts. Any such shortage, constraint or delay may result in delays in shipments of products or components, which could adversely affect NTIC’s net sales and other operating results, and its reputation. From time to time, materials and components used in NTIC’s products are subject to allocation because of shortages of these materials and components. With respect to NTIC’s Natur-Tec^® resin compounds and finished products, there are a limited number of suppliers of the base resins used to manufacture NTIC’s Natur-Tec^® resin compounds and finished products, and in the past, NTIC has experienced some delay in obtaining such base resins. In addition, a number of raw materials and purchased parts used in NTIC’s rust and corrosion inhibiting products and Natur-Tec^® finished products are sourced from suppliers who currently serve as NTIC’s sole source of supply for these components. Future shortages of materials and components could cause delayed shipments and customer dissatisfaction and adversely affect net sales.

Increases in prices for raw materials and components used in NTIC’s products could adversely affect NTIC’s operating results.

NTIC uses certain raw materials and components in its products, including in particular plastic resins, which are subject to price increases. Changes to international trade agreements could result in additional tariffs, duties or other charges on raw materials or components we import into the U.S. Increases in prices for raw materials and components used in NTIC’s products could adversely affect NTIC’s gross margins and other operating results.

The commercial success of NTIC’s Natur-Tec^® resin compounds and finished products depends on the widespread market acceptance of products manufactured with biobased and biodegradable resins.

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

NTIC’s business, properties and products are subject to governmental regulation and taxes, compliance with which may require NTIC to incur expenses or modify its products or operations, and which may expose NTIC to penalties for non-compliance. Governmental regulation also may adversely affect the demand for some of NTIC’s products and its operating results.

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

U.S. federal income tax reforms could adversely affect NTIC’s business, results of operations or financial conditions.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (Tax Reform Act). The Tax Reform Act makes broad and complex changes to the U.S. corporate income tax system and includes a Transition Toll Tax (Toll Tax), which is a one-time mandatory deemed repatriation tax on accumulated foreign subsidiaries’ previously untaxed foreign earnings. The Toll Tax will be paid over an eight-year period, starting in 2018, and will not accrue interest. The Tax Reform Act also imposed a global intangible low-taxed income tax (GILTI), which is a new tax on certain off-shore earnings at an effective rate of 10.5% for tax years beginning after December 31, 2017 (increasing to 13.125% for tax years beginning after December 31, 2025) with a partial offset for foreign tax credits. NTIC continues to analyze the impact the Tax Reform Act may have on NTIC’s business, results of operations or financial conditions. U.S Treasury regulations, administrative interpretations or court decisions interpreting the Tax Reform Act may require changes in NTIC’s estimates, which could have a material adverse effect on NTIC’s business, results of operations or financial conditions.

Fluctuations in NTIC’s effective tax rate could have a significant impact on NTIC’s financial position, results of operations or cash flows.

The mix of pre-tax income or loss among the tax jurisdictions in which NTIC operates that have varying tax rates could impact NTIC’s effective tax rate. NTIC is subject to income taxes as well as non-income based taxes, in both the United States and various foreign jurisdictions. Judgment is required in determining the worldwide provision for income taxes, other tax liabilities, interest and penalties. Future events could change management’s assessment. NTIC operates within multiple taxing jurisdictions and is subject to tax audits in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. NTIC also has made assumptions about the realization of deferred tax assets. Changes in these assumptions could result in a valuation allowance for these assets. Final determination of tax audits or tax disputes may be different from what is currently reflected by NTIC’s income tax provisions and accruals.

NTIC may grow its business through additional joint ventures, subsidiaries, alliances and acquisitions, which could be risky and harm its business.

One of NTIC’s growth strategies may be to expand its business by entering into additional joint ventures and alliances and acquiring businesses, technologies and products that complement or augment NTIC’s existing products. The benefits of a joint venture, alliance or acquisition may take more time than expected to develop, and NTIC cannot guarantee that any future joint ventures, alliances or acquisitions will in fact produce the intended benefits. In addition, joint ventures, alliances and acquisitions involve a number of risks, including:

NTIC’s ability to grow through joint ventures, alliances and acquisitions will depend, in part, on the availability of suitable opportunities at an acceptable cost, NTIC’s ability to compete effectively for these opportunities and the availability of capital to complete such transactions.

NTIC relies on its joint ventures, distributors, manufacturer’s sales representatives and other agents to market and sell its products.

In addition to its direct sales force, NTIC relies on its joint ventures, distributors, manufacturer’s sales representatives and other agents to market and sell its products in the United States and internationally. NTIC’s joint ventures, distributors, manufacturer’s sales representatives and other agents might terminate their relationship with NTIC or devote insufficient sales efforts to NTIC’s products. NTIC does not control its joint ventures, distributors, manufacturer’s sales representatives and other agents and they may not be successful in implementing NTIC’s marketing plans. NTIC’s failure to maintain its existing relationships with these entities, or its failure to recruit and retain additional skilled joint venture partners, distributors, manufacturer’s sales representatives and other agents could have an adverse effect on NTIC’s operations. It is anticipated that several of NTIC’s joint venture partners will retire during the next several years which will require a transition on the part of the joint venture as well as NTIC and could harm NTIC’s relationship with the joint venture and NTIC’s business.

NTIC may be subject to product liability claims or other claims arising out of the activities of its joint ventures, which could adversely affect NTIC and its business.

While NTIC is not aware of any specific potential risk beyond its initial investment in and any undistributed earnings of each of its joint ventures, there can be no assurance that NTIC will not be subject to lawsuits based on product liability claims or other claims arising out of the activities of its joint ventures. To mitigate the ramifications of such an occurrence, NTIC maintains liability insurance specifically applicable to its ownership positions in its joint venture arrangements in excess of any insurance the joint ventures may maintain. No assurance can be provided, however, that such insurance will be available or adequate in the event of a claim.

The sale ofZERUST^®rust and corrosion inhibiting products into the oil and gas industry is especially risky in light of the hazards typically associated with such operations and the significant amount of potential liability involved, which could adversely affect NTIC’s business if ZERUST^®rust and corrosion inhibiting products are involved, even if the cause of such events was not related to NTIC’s products.

Because NTIC sells its ZERUST^® rust and corrosion inhibiting products into the oil and gas industry, NTIC is subject to some of the risks and hazards typically associated with such operations, including hazards such as fire, explosion, blowouts, cratering, unplanned gas releases and spills, each of which could be claimed to be attributed to the failure of NTIC’s products to perform as anticipated. If such events occur and NTIC’s products are involved, NTIC’s business and operating results may suffer even if the cause of such events was not related to NTIC’s products.

The sale ofZERUST^®rust and corrosion inhibiting products into the oil and gas industry is somewhat seasonal and dependent upon oil prices.

During fiscal 2015,In the past, NTIC has experienced some seasonality with respect to the sale of its ZERUST^® rust and corrosion inhibiting products into the oil and gas industry, with sales during parts of the second and third fiscal quarters being adversely affected by winter in the United States. In addition, although not anticipated, the sale of NTIC’s ZERUST^® rust and corrosion inhibiting products into the oil and gas industry, wereparticularly in the United States, have been and may continue to be hampered by low global crude oil prices, which NTIC believes constrainedconstrains capital improvement budgets of its existing and prospective customers.customers and may result in personnel turnover at its oil and gas customers or prospects.

Severe weather could have a material adverse effect on our business.

Our business could be materially and adversely affected by severe weather. Our customers, including in particular our oil and gas customers, may have operations located in parts of the southern United States or other places and may be adversely affected by hurricanes and tropical storms, resulting in reduced demand for our products and services or increased operating costs. Furthermore, our customers and raw material suppliers’ operations may be adversely affected by such hurricanes and other extreme or seasonal weather conditions. Adverse weather can also directly impede our own operations. Repercussions of severe weather conditions may include:

These constraints could delay our operations and materially increase our operating and capital costs.

NTIC has limited staffing and will continue to be dependent upon key employees.

NTIC’s success is dependent upon the efforts of a small management team and group of employees. NTIC’s future success will depend in large part on its ability to retain its key employees and identify, attract and retain other highly qualified managerial, technical, research and development, sales and marketing and customer service personnel when needed. Competition for these individuals may be intense, especially in the markets in which NTIC operates. NTIC may not succeed in identifying, attracting and retaining these personnel. Inadequate performance by any of NTIC’s limited staff could have a negative impact on the performance of the company. NTIC’s current management, other than its President and Chief Executive Officer, does not have any material stock ownership in NTIC. In addition, none of NTIC’s employees hashave any contractual obligation to maintain his or her employment with NTIC. The loss or interruption of services of any of NTIC’s key personnel, including in particular its technical personnel, the inability to identify, attract or retain qualified personnel in the future, delays in hiring qualified personnel, or any employee slowdowns, strikes or similar actions could make it difficult for NTIC to manage its business and meet key objectives, which could harm NTIC’s business, financial condition and operating results.

Given NTIC’s limited resources, it may not effectively manage its growth.

NTIC’s strategy to grow its business, including in particular its ZERUST^® rust and corrosion inhibiting products for the oil and gas industry and its Natur-Tec^® bio-plastic resin compounds and finished products, requires significant management time and operational and financial resources. There is no assurance that NTIC has the necessary operational and financial resources to manage its growth. This is especially true as it expands facilities and manufactures its products on a larger commercial scale. In addition, rapid growth in NTIC’s headcount and operations may place a significant strain on its management, administrative, operational and financial infrastructure. Failure to adequately manage its growth could have a material and adverse effect on NTIC’s business, financial condition and operating results. For example, NTIC’s soil side bottom solutions for tanks require implementation teams comprised of both internal NTIC personnel and outside consulting firms. NTIC’s failure to expand these implementation teams to service additional customers may limit NTIC’s ability to grow this business. In addition, NTIC may not be successful in its strategy to grow its business.

Certain of NTIC’s operations are subject to regulation by the U.S. Food and Drug Administration.

The manufacture, sale and use of NTIC’s Natur-Tec^® bio-plastic resin compounds are subject to regulation by the U.S. FDA. The FDA’s regulations are concerned with substances used indirectly in food packaging materials, not with specific finished food packaging products. Thus, food and beverage containers are in compliance with FDA regulations if the components used in the food and beverage containers: (i) are approved by the FDA as indirect food additives for their intended uses and comply with the applicable FDA indirect food additive regulations; or (ii) are generally recognized as safe for their intended uses and are of suitable purity for those intended uses. NTIC believes that its Natur-Tec^® resin compounds are in compliancecomply with all FDA requirements. However, failure to comply with FDA regulations could subject NTIC to administrative, civil or criminal penalties.

NTIC relies on its management information systems for inventory management, distribution and other functions. If these information systems fail to adequately perform these functions or if NTIC experiences an interruption in their operation, NTIC’s business and operating results could be adversely affected.

The efficient operation of NTIC’s business is dependent on its management information systems. NTIC relies on its management information systems to effectively manage accounting and financial functions; manage order entry, order fulfillment and inventory replenishment processes; and to maintain its research and development data. The failure of management information systems to perform as anticipated could disrupt NTIC’s business and product development and could result in decreased sales, causing NTIC’s business and operating results to suffer. In addition, NTIC’s management information systems are vulnerable to damage or interruption from natural or man-made disasters, terrorist attacks and attacks by computer viruses or hackers, or power loss or computer systems, Internet, telecommunications or data network failure. Any such interruption could adversely affect NTIC’s business and operating results.

NTIC’s business could be negatively impacted by cyber security threats.

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

NTIC’s reliance upon patents, trademark laws, trade secrets and contractual provisions to protect its proprietary rights may not be sufficient to protect its intellectual property from others who may sell similar products.

NTIC holds patents relating to various aspects of its products and believes that proprietary technical know-how is critical to many of its products. Proprietary rights relating to NTIC’s products are protected from unauthorized use by third parties only to the extent that they are covered by valid and enforceable patents or are maintained in confidence as trade secrets. NTIC cannot be certain that it will be issued any patents from any pending or future patent applications owned by or licensed to NTIC or that the claims allowed under any issued patents will be sufficiently broad to protect its technology. In the absence of patent protection, NTIC may be vulnerable to competitors who attempt to copy NTIC’s products or gain access to its trade secrets and know-how. NTIC’s competitors may initiate litigation to challenge the validity of NTIC’s patents, or they may use their resources to design comparable products that do not infringe NTIC’s patents. NTIC may incur substantial costs if its competitors initiate litigation to challenge the validity of its patents or if it initiates any proceedings to protect its proprietary rights and if the outcome of any such litigation is unfavorable to NTIC, its business and operating results could be materially adversely affected.

In addition, NTIC relies substantially on trade secrets and proprietary know-how that it seeks to protect, in part, by confidentiality agreements with its employees, and consultants. These agreements may be breached, and NTIC may not have adequate remedies for any such breach. Even if these confidentiality agreements are not breached, NTIC’s trade secrets may otherwise become known or be independently developed by competitors.

NTIC may not achieve its annual financial guidance or projected goals and objectives in the time periods that NTIC anticipates or announces publicly, which could have an adverse effect on NTIC’s business and could cause its stock price to decline.

On a quarterly basis, NTIC typically provides projected annual financial information, including its anticipated annual net sales and net earnings. These financial projections are based on management’s then currentthen-current expectations and typically do not contain any margin of error or cushion for any specific uncertainties, or for the uncertainties inherent in all financial forecasting. The failure to achieve such financial projections could have an adverse effect on NTIC’s business, disappoint investors and analysts and cause its stock price to decline.

NTIC also sets goals and objectives for, and makes public statements regarding, the timing of certain accomplishments and milestones regarding its business, such as its progress in selling its ZERUST^® rust and corrosion inhibiting products and services to customers in the oil and gas industry, the progress and timing of its various field trials with prospective customers in the oil and gas industry, its ability to increase sales of its Natur-Tec^® resin compounds and finished products, and other developments and milestones. The actual timing of these events can vary dramatically due to a number of factors including without limitation the timing of the receipt of purchase orders, delays or failures in current field trials, the amount of time, effort and resources committed to the sales and marketing of NTIC’s products and services by NTIC and its current and potential future distributors and agents and the uncertainties inherent in introducing new products and services. As a result, there can be no assurance that NTIC will succeed in achieving its projected goals and objectives in the time periods that NTIC anticipates or announces publicly. The failure to achieve such projected goals and objectives in the time periods that NTIC anticipates or announces publicly could have an adverse effect on NTIC’s business, disappoint investors and analysts and cause its stock price to decline.

NTIC’s quarterly results are typically unpredictable and subject to variation.

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

As a result of NTIC’s status as an “accelerated filer” under SEC rules, NTIC is subject to additional SEC disclosure and other rules and regulations, which will cause NTIC to incur additional costs to comply with such rules and regulations and the non-compliance of which may have an adverse effect on NTIC’s operating results.

Beginning in fiscal 2015, NTIC became an “accelerated filer” under SEC rules and, as a result, is subject to additional SEC disclosure and other rules and regulations, such as additional financial statement requirements with respect to its joint ventures, the requirement of its independent registered public accounting firm to attest to NTIC’s management’s report on the effectiveness of NTIC’s internal control over financial reporting and the requirement of NTIC to comply with certain additional disclosures rules and regulations, including the requirement to include additional executive compensation disclosures in its proxy statement in connection with its annual meeting of stockholders. NTIC’s compliance with such additional rules and regulations may result in additional expense, which may adversely affect its operating results.

NTIC is exposed to risks relating to its evaluation of its internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Sarbanes-Oxley Act of 2002 and related and other regulations implemented by the SEC and the NASDAQNasdaq Stock Market, are challenging for small publicly-held companies, including NTIC. NTIC’s efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, significant general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. In particular, NTIC’s efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding NTIC’s assessment of its internal control over financial reporting have required and will continue to require the expenditure of significant financial and managerial resources, especially in light of NTIC’s new status as an “accelerated filer” under SEC rules.resources. Although NTIC’s management has concluded that NTIC’s internal control over financial reporting was effective as of August 31, 2015 and NTIC’s independent registered public accounting firm agreed,2018, no assurance can be provided that NTIC’s management or independent registered public accounting firm will reach a similar conclusion as of any later date. NTIC’s failure to maintain effective internal control over financial reporting may have an adverse effect on its stock price.

NTIC’s compliance with accounting principles generally accepted in the United States of America and any changes in such principles might adversely affect NTIC’s operating results and financial condition. Any requirement to consolidate NTIC’s joint ventures or subject them to compliance with the internal control provisions of the Sarbanes-Oxley Act of 2002 could adversely affect NTIC’s operating results and financial condition.

If there were a change in accounting rules and NTIC were required to fully consolidate its joint ventures or if NTIC’s joint ventures otherwise would be required to be consolidated with NTIC, or be in compliance with the internal control provisions of the Sarbanes-Oxley Act of 2002, NTIC and the individual joint venture would incur significant additional costs. In addition, other accounting pronouncements issued in the future could have a material cost associated with NTIC’s implementation of such new accounting pronouncements.

NTIC’s business is subject to a number of other miscellaneous risks that may adversely affect NTIC’s operating results, financial condition or business.

NTIC’s business is subject to a number of other miscellaneous risks that may adversely affect NTIC’s operating results, financial condition or business, such as natural or man-made disasters, an unexpected loss of supply due to a force majeure event or global pandemics that may result in shortages of raw materials, higher commodity costs, an increase in insurance premiums and other adverse effects on NTIC’s business; the continued threat of terrorist acts and war that may result in heightened security and higher costs for import and export shipments of components or finished goods; and the ability of NTIC’s management to adapt to unplanned events.

Risks Related to NTIC’s Common Stock

The trading volume of NTIC’s common stock is typically very low, leaving NTIC’s common stock open to risk of high volatility.

The number of shares of NTIC’s common stock being traded on a daily basis is often very low and on some trading days, there is no trading volume at all. During fiscal 2015,2018, the daily trading volume ranged from zero shares to 80,30047,000 shares. Any NTIC stockholder wishing to sell his, her or its stock may cause a significant fluctuation in the trading price of NTIC’s common stock. In addition, low trading volume of a stock increases the possibility that, despite rules against such activity, the price of the stock may be manipulated by persons acting in their own self-interest. NTIC may not have adequate market makers and market making activity to prevent manipulation in its common stock.

The price and trading volume of NTIC’s common stock has been, and may continue to be, volatile.

The market price and trading volume of NTIC’s common stock price historically has fluctuated over a wide range. During fiscal 2015,2018, the sale price of NTIC’s common stock ranged from a low of $14.98$15.75 per share to a high of $24.85$41.90 per share, and the daily trading volume ranged from zero shares to 80,30047,000 shares. It is likely that the price and trading volume of NTIC’s common stock will continue to fluctuate in the future. The securities of small capitalization companies, including NTIC, from time to time experience significant price and volume fluctuations, often unrelated to the operating performance of these companies. Securities class action litigation is sometimes brought against a company following periods of volatility in the market price of its securities or for other reasons. NTIC may become the target of similar litigation, especially if we failNTIC fails to meet ourits annual projected financial guidance or lower ourits annual projected financial guidance. Securities litigation, whether with or without merit, could result in substantial costs and divert management’s attention and resources, which could harm NTIC’s business, financial condition, and operating results, as well as the market price of its common stock.

A large percentage of NTIC’s outstanding common stock is held by insiders, and, as a result, the trading market for NTIC’s common stock is not as liquid as the stock of other public companies.

As of November 10, 2015,9, 2018, NTIC had 4,538,3174,542,177 shares of common stock outstanding, of which 19.2%21.0% of these outstanding shares were beneficially owned by directors, executive officers, principal stockholders and their respective affiliates. The stock of companies with a substantial amount of stock held by insiders is usually not as liquid as the stock of other public companies where insider ownership is not as concentrated. Thus, the trading market for shares of NTIC’s common stock may not be as liquid as the stock of other public companies.

If securities or industry analysts do not publish research or reports about NTIC’s business, or if they adversely change their recommendations regarding NTIC’s common stock, the market price for NTIC’s common stock and trading volume could decline.

The trading market for NTIC’s common stock has been influenced by research or reports that industry or securities analysts publish about NTIC or its business. If one or more analysts who cover NTIC downgrade NTIC’s common stock, the market price for NTIC’s common stock would likely decline. If one or more of these analysts cease coverage of NTIC or fail to regularly publish reports on NTIC, NTIC could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for NTIC’s common stock to decline.

NTIC does not intend to pay dividends for the foreseeable future.

Although in the past NTIC has paid dividends on its common stock, NTIC has not done so since fiscal 2005. The payment of any future dividends will be determined by NTIC’s Board of Directors in light of conditions then existing, including NTIC’s earnings (if any), financial condition, cash requirements, restrictions in financing agreements, business conditions and other factors. NTIC’s Board of Directors currently does not anticipate paying a dividend on NTIC’s common stock in the near future, but rather intends to retain all of its earnings for the foreseeable future to finance the operation and expansion of its business. As a result, NTIC’s stockholders will only receive a return on their investment in NTIC’s common stock if the market price of NTIC’s common stock increases.

One of NTIC’s principal stockholders beneficially owns a significant percentage of NTIC’s outstanding common stock and is affiliated with NTIC’s President and Chief Executive Officer and thus may be able to influence matters requiring stockholder approval, including the election of directors, and could discourage or otherwise impede a transaction in which a third party wishes to purchase NTIC’s outstanding shares at a premium.

As of November 10, 2015,9, 2018, Inter Alia Holding Company, or Inter Alia, beneficially owned approximately 13.3% of NTIC’s outstanding common stock. Inter Alia is an entity partially owned by G. Patrick Lynch, NTIC’s President and Chief Executive Officer and a director, as well as threetwo other members of the Lynch family. Mr. Lynch shares voting and dispositive power of shares of NTIC’s common stock held by Inter Alia with the other owners. As a result of his share ownership through Inter Alia and his position as President and Chief Executive Officer and a director of NTIC, Mr. Lynch may be able to influence the affairs and actions of NTIC, including matters requiring stockholder approval, such as the election of directors and approval of significant corporate transactions. The interests of Mr. Lynch and Inter Alia may differ from the interests of NTIC’s other stockholders. This concentration of ownership may have the effect of delaying, preventing or deterring a change in control of NTIC, could deprive NTIC’s stockholders of an opportunity to receive a premium for their common stock as part of a sale or merger of NTIC and may negatively affect the market price of NTIC’s common stock. Transactions that could be affected by this concentration of ownership include proxy contests, tender offers, mergers or other purchases of common stock that could give stockholders the opportunity to realize a premium over the then-prevailing market price for shares of NTIC’s common stock.

Future equity issuances by NTIC may have dilutive and other effects on NTIC’s existing stockholders.

As of November 10, 2015, there were 4,538,317 shares of NTIC’s common stock outstanding, and in addition, security holders held options, which, if vested and exercised, would obligate NTIC to issue up to 295,181 additional shares of common stock. It is expected that such shares, when NTIC issues them upon exercise, will be available for immediate resale in the public market. The market price of NTIC’s common stock could fall as a result of sales of these shares of common stock due to the increased number of shares available for sale in the market. Any issuances by NTIC of equity securities may be at or below the prevailing market price of NTIC’s common stock and may have a dilutive impact on NTIC’s existing stockholders. These issuances or other dilutive issuances also would cause NTIC’s net income per share, if any, to decrease in future periods. As a result, the market price of NTIC’s common stock could decrease.

Not applicable.

Item 4A. EXECUTIVE OFFICERS OF THE REGISTRANT

The two individuals named below have been designated by NTIC’s Board of Directors as “executive officers” of NTIC. Their ages and the offices held, as of November 10, 2015,9, 2018, are as follows:

G. Patrick Lynch, an employee of NTIC since 1995, has been President since July 2005 and Chief Executive Officer since January 2006 and was appointed a director of NTIC in February 2004. From July 2005 to January 2006, Mr. Lynch served as Chief Operating Officer of NTIC.  Mr. Lynch served as President of North American Operations of NTIC from May 2004 to July 2005.  Prior to May 2004, Mr. Lynch held various positions with NTIC, including Vice President of Strategic Planning, Corporate Secretary and Project Manager.

Business Overview

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’s primary business is corrosion prevention marketed mainly under the ZERUST® brand. NTIC has been selling its proprietary ZERUST® 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 biobased and certified compostable (fully biodegradable) polymer resinsresin compounds and finished products under the Natur-Tec® brand. These products are intended to reduce NTIC’s customers’ carbon footprint and provide environmentally sound waste disposal options.

NTIC’s ZERUST®ZERUST^® rust and corrosion inhibiting products include plastic and paper packaging, liquids, and coatings, rust removers, cleaners, and cleaners, diffusers, andas 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’s technical service consultants work directly with the end users of NTIC’s ZERUST®ZERUST^® rust and corrosion inhibiting products to analyze their specific needs and develop systems to meet their technicalperformance requirements. In North America, NTIC sells its ZERUST®ZERUST^® corrosion prevention solutions through a direct sales force as well as a network of independent distributors and agents.agents supported by a direct sales force. Internationally, NTIC sells its ZERUST®ZERUST^® corrosion prevention solutions through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd. (NTIC China), its majority-owned subsidiary in Brazil, Zerust Prevenção de Corrosão S.A. (Zerust Brazil), its majority-owned joint venture holding company for NTIC’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 Prevenção de Corrosão 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).

One of NTIC’s strategic initiatives is to expand into and penetrate other markets for its ZERUST®ZERUST^® corrosion prevention solutions.technologies. Consequently, for the past several years, NTIC has focused itssignificant 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®ZERUST^® 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.

NTIC markets and sells its ZERUST® rust and corrosion prevention solutions to customers in the oil and gas industry across several countries either directly, through its subsidiaries or through NTIC’sits joint venture partners and other strategic partners. The sale of ZERUST® corrosion prevention solutions to customers in the oil and gas industry typically involves a long sales cycle,cycles, often including a one- to multi-year trial periodperiods with each customer and a slow integration process thereafter.

Natur-Tec®Natur-Tec^® biobased and compostable plastics are manufactured using NTIC’s patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec®Natur-Tec^® 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 resinsresin 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, can liners, pet waste collectionbranded apparel packaging bags and accessories, and various foodservice ware items, such as disposable cutlery, packaging foamdrinking straws, food-handling gloves and coated paper products. In North America, NTIC markets its Natur-Tec® resinsNatur-Tec^® 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®Natur-Tec^® bioplastic products. Internationally, NTIC sells its Natur-Tec® resinsNatur-Tec^® resin compounds and finished products both directly and through its wholly-owned subsidiary in China, NTIC China, its majority-owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India), and through distributors and certain joint ventures. In November 2014, NTIC entered into an agreement with NatureWorks LLC for joint marketing and sales of Ingeo® based packaging solutions to customers in India. With recent Indian government mandates banning use of non-biodegradable plastics in certain types of food and consumer packaging, NTIC expects the market in India for bioplastic packaging solutions to grow substantially.

Termination of Chinese Joint Venture

On January 2, 2015, NTIC announced that, effective as of December 31, 2014, it is selling its ZERUST® products and services in China through a wholly-owned subsidiary, NTIC (Shanghai) Co., Ltd. (NTIC China), and has terminated its joint venture agreements with Tianjin-Zerust Anticorrosion Co., Ltd. (Tianjin Zerust).  NTIC and NTI Asean have filed a lawsuit against Mr. Tao Meng, a Chinese national and the former joint venture entity’s other shareholder, and his spouse in the Chinese court of Tianjin, seeking, among other things, an orderly liquidation of Tianjin Zerust.

NTIC indirectly has a 30% ownership interest in Tianjin Zerust through its 60% owned holding company subsidiary, NTI Asean LLC.  Commencing during the second quarter of fiscal 2015, NTIC’s consolidated financial statements include the financial results of NTIC China.  NTIC anticipates that NTIC’s net sales, costs of goods sold and operating expenses will increase and its equity in income from joint ventures and fee income for services provided to its joint ventures will decrease in future periods compared to the comparable prior fiscal year periods as NTIC started recognizing Tianjin Zerust based on its carrying value instead of the equity method and will continue to do so until Tianjin Zerust is fully liquidated. 

NTIC anticipates that it may take several quarters to transition many of the previous customers of Tianjin Zerust to NTIC China and no assurance can be provided that NTIC China will be able to achieve the net sales and income levels previously achieved by Tianjin Zerust.   For fiscal 2014, Tianjin Zerust had net sales of $15.9 million and net income of $1.3 million.  The operating income of the joint venture before paying royalties in an aggregate amount of $4.2 million to all shareholders was over $5.5 million; NTIC’s indirect ownership of Tianjin Zerust is 30%. 

During fiscal 2015, NTIC incurred approximately $1,640,000 in start-up expenses related either directly or indirectly to the establishment of NTIC China, the termination of the joint venture agreements with Tianjin Zerust and its pending litigation against Mr. Tao Meng and his spouse, and the anticipated liquidation of Tianjin Zerust and against Cortec Corporation. These expenses are recorded as selling, general and administrative expenses and expenses incurred in support of joint ventures on the consolidated statements of operations.

NTIC expects that its operating results may be volatile over the next few quarters as a result of NTIC’s Chinese operations. 

NTIC’s Subsidiaries and Joint Venture Network

NTIC has ownership interests in six operating subsidiaries in North America, South America, Europe and Asia. The following table sets forth a list of NTIC’s operating subsidiaries as of November 9, 2018, the country in which the subsidiary is organized and NTIC’s ownership percentage in each subsidiary:

The results of these subsidiaries are fully consolidated in NTIC’s consolidated financial statements.

NTIC participates in 1920 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’s joint ventures exclusively sell rust and corrosion inhibiting products, some of the joint ventures also sell NTIC’s Natur-Tec® resin compounds. NTIC has historically funded its investments in joint ventures with cash generated from operations.

NTIC’s receipt ofreceives funds from its joint ventures is dependent uponas fees for services that NTIC provides to its joint ventures based primarily on the net sales of the individual joint ventures, and NTIC’s receipt ofas dividend distributions from the joint ventures.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’s joint venture in Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for such services. NTIC recognizes equity income from itseach joint venturesventure based on the overall profitability of itsthe joint ventures.venture. Such profitability is subject to variability from quarter to quarter which, in turn, subjects NTIC’s earnings to variability from quarter to quarter. The profits of NTIC’seach joint venturesventure 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.

NTIC accounts for the investments and financial results of its joint ventures in its financial statements utilizing the equity method of accounting.

The results of Zerust Brazil, NTI Asean and Natur-Tec India, and as of December 31, 2014, NTIC China, are fully consolidated in NTIC’s consolidated financial statements. NTIC holds 85% of the equity and 85% of the voting rights of Zerust Brazil. NTIC holds 60% of the equity and 60% of the voting rights of NTI Asean. NTI Asean holds investments in eight entities that operate in the following eight territories located in the ASEAN region: China (although liquidation was initiated December 31, 2014), Indonesia, South Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand. NTIC holds 90% of the equity and 90% of the voting rights of Natur-Tec India. NTIC China is a wholly-owned subsidiary of NTIC.

NTIC considers EXCOR and its former joint venture in China, Tianjin Zerust, to be individually significant to NTIC’s consolidated assets and income;income, and therefore, provides certain additional information regarding EXCOR and Tianjin Zerustit in the notes to NTIC’s consolidated financial statements and in this section of this report.

For fiscal 2015, 2014 and 2013, EXCOR met the conditions of a significant subsidiary of NTIC under Rule 1-02(w) of Regulation S-X. Pursuant to Rue 3-09 of Regulation S-X, NTIC intends to file an amendment to this report containing separate audited financial statements for EXCOR.

Financial Overview

NTIC’s management, including its chief executive officer who is NTIC’s chief operating decision maker, reports and manages NTIC’s operations in two reportable business segments based on products sold, customer base and distribution center: ZERUST® products and services and Natur-Tec® products.

NTIC’s consolidated net sales increased 13.0%30.0% during fiscal 20152018 compared to fiscal 2014.2017. This increase was primarily a result of increased demand forof ZERUST® rust and corrosion inhibiting packaging products and services and the addition of new customers in North America and China and an increase in sales of Natur-Tec® products and, to some extent, sales at NTIC China, which subsidiary did not exist during fiscal 2014. products.

During fiscal 2015, 85.9%2018, 80.5% of NTIC’s consolidated net sales were derived from sales of ZERUST®ZERUST^® products and services, which increased 9.2%26.2% to $26,042,909$41,374,305 during fiscal 20152018 compared to $23,845,288$32,789,283 during fiscal 2014.2017. This increase was due to increased demand from bothof ZERUST® rust and corrosion inhibiting packaging products and services and the addition of new customers in North America and existing customers for new and existing products.China. NTIC has focused its sales efforts of ZERUST® 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’s consolidated net sales for fiscal 20152018 included $1,886,814$3,066,953 of sales made to customers in the oil and gas industry compared to $1,702,130$1,720,162 for fiscal 2014.2017. Overall demand for ZERUST® products and services depends heavily on the overall health of the markets in which NTIC sells its products, including the automotive, marketoil and gas, agriculture, and mining markets in particular.

During fiscal 2015, 14.1%2018, 19.5% of NTIC’s consolidated net sales were derived from sales of Natur-Tec®Natur-Tec^® products compared to 11.1%17.1% during fiscal 2014.2017. Net sales of Natur-Tec®Natur-Tec^® products increased 43.6%48.2% to $4,279,785$10,050,516 during fiscal 20152018 compared to fiscal 20142017 primarily due to an increase in finished product sales in North America and finished product sales at NTIC’s majority-ownedmajority owned subsidiary in India, Natur-Tec India Private Limited (Natur-Tec India).

Cost of goods sold as a percentage of net sales increased to 67.8% during fiscal 2015 compareddecreased slightly to 66.4% during fiscal 20142018 compared to 66.5% during fiscal 2017. This decrease was primarily as a result of increased net sales during fiscal 2015 of Natur-Tec® products, which carry lower margins thanand cost reductions realized on the raw materials associated with NTIC’s ZERUST® industrial products.

NTIC’s equity in income from joint ventures increased 0.3%27.6% to $5,936,565$7,527,383 during fiscal 20152018 compared to $5,920,603$5,898,908 during fiscal 2014.2017. This increase was primarily due to increasesa corresponding increase in profitability at the joint ventures, partially offset by decreases associated with the anticipated liquidation of Tianjin Zerust and adverse effects of foreign currency exchange rate fluctuations, including in particular the Euro compared to the U.S. dollar. NTIC recognized a 29.8% decrease in fees for services provided to joint ventures during fiscal 2015 compared to fiscal 2014 primarily due to the anticipated liquidation of Tianjin Zerust. Fees for services provided to Tianjin Zerust decreased $1,623,938 to $494,080 during fiscal 2015 compared to $2,118,018 during fiscal 2014. Additionally, there was a decrease innet sales at the joint ventures, which were $99,026,251$120,060,897 during fiscal 2015,2018, compared to $118,848,890$101,261,132 during fiscal 2014. This decrease2017. The increase in the net sales of NTIC’s joint ventures was due primarily to higher sales from existing customers for new and existing products due to increased demand. The increase in net sales of NTIC’s joint ventures resulted in a corresponding decreaseincrease in fees for services provided to joint ventures as such fees are a function of net sales of NTIC’s joint ventures. Net sales of NTIC’s joint ventures decreased also as a result of a significant weakening of the Euro compared to the U.S. dollar and, to a lesser extent, the sale in November 2013 of NTIC’s ownership interest in Mütec GmbH.

NTIC’s total operating expenses increased 11.4%$2,908,188, or 14.5%, to $18,267,173$22,911,454 during fiscal 20152018 compared to $16,392,035$20,003,266 in fiscal 2014.2017. This increase was primarily due to $1,642,258an increase in expenses related to the formation and establishment of NTIC China and the anticipated liquidation of Tianjin Zerust. Such expenses consisted primarily of legal andNTIC’s personnel expenses associated within North America and China, including an increase in the establishmentmanagement bonus accrual of the subsidiary, the hiring of new personnel and initial operations.$1,138,000.

NTIC expenses all costs related to productspent $3,524,953 in fiscal 2018 in connection with its research and development as incurred. NTIC incurred $4,047,279 of research and development expense during fiscal 2015activities, compared to $4,368,752 during$2,912,393 in fiscal 2014. These represent net amounts after being reduced by reimbursements related to certain research and development contracts. Such reimbursements totaled $0 and $45,788 for fiscal 2015 and 2014, respectively.2017. NTIC anticipates that it will spend between $4,000,000$3,200,000 and $4,400,000$3,600,000 in total during fiscal 20162019 on research and development activities related to its new technologies. This estimate is a net range after being reduced by anticipated reimbursements related to certain research and development contracts.activities.

Net income attributable to NTIC decreased 56.4%,increased to $1,789,571,$6,701,366, or $0.39$1.43 per diluted common share, for fiscal 20152018 compared to $4,106,372,net income of $3,422,126, or $0.90$0.75 per diluted common share, for fiscal 2014.2017. This decreaseincrease was primarily the result of the decreaseincrease in net sales and corresponding gross profit, as well as the increase in income from NTIC’s joint venture operations, partially offset by the increase in operating expenses, as a resultpreviously described. This increase was partially offset by the impact of the anticipated liquidationone-time provisional adjustment of Tianjin Zerust$700,000 related to the Tax Cuts and the establishment of NTIC China.Jobs Act (Tax Reform Act), as described in more detail below.

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 and sales of its ZERUST®ZERUST^® products and services into the oil and gas industry and Natur-Tec®Natur-Tec^® bioplastics products, which sales fluctuate more on a quarterly basis than the traditional ZERUST®ZERUST^® business. NTIC also anticipates that its operating results during the next few quarters will remain volatile primarily as a result of the changes in its Chinese operations.

NTIC’s working capital, as defined as current assets less current liabilities, was $15,603,771$22,837,591 at August 31, 2015,2018, including $2,623,981$4,163,023, in cash and cash equivalents and $2,027,441$3,300,110 in available for sale securities, compared to $17,853,311$21,173,001 at August 31, 2014,2017, including $2,477,017$6,360,201 in cash and cash equivalents and $5,519,766$3,766,984 in available for sale securities.

Sales and Expense Components

The following is a description of the primary components of net sales and expenses:

Net Sales, Excluding Joint Ventures. NTIC derives net sales from the sale of its ZERUST^® products and services and its Natur-Tec^® products. NTIC sells its ZERUST^® products and services and its Natur-Tec^® products either directly, through its subsidiaries or via a network of joint ventures, independent distributors and agents. Net sales, excluding joint ventures represents net sales by NTIC either directly to end users or to distributors worldwide, but not sales to NTIC’s joint ventures and not sales by NTIC’s joint ventures. NTIC recognizes revenue from the sale of its products when persuasive evidence of an arrangement exists, the product has been delivered, the fee is fixed and determinable and collection of the resulting receivable is reasonably assured, all of which criteria are generally met upon shipment when risk of loss and title passes to the customer or distributor. NTIC records all amounts billed to customers and distributors in a sales transaction related to shipping and handling as sales and records costs related to shipping and handling in cost of goods sold.

Net Sales, To Joint Ventures. Net sales, to joint ventures represents net sales by NTIC to NTIC’s joint ventures, but not sales by NTIC either directly to end users or to distributors or sales by NTIC’s joint ventures. NTIC’s revenue recognition policy for sales to its joint ventures is the same as NTIC’s policy for sales to unaffiliated customers. NTIC recognizes revenue from the sale of its products to joint ventures when persuasive evidence of an arrangement exists, the product has been delivered, the fee is fixed and determinable and collection of the resulting receivable is reasonably assured, all of which criteria are generally met upon shipment when risk of loss and title passes to the joint venture.

Cost of Goods Sold. Most of NTIC’s products are manufactured by third parties and its cost of goods sold for those products consists primarily of the price invoiced by its third-party vendors. For the portion of products that NTIC manufactures, NTIC’s cost of goods sold for those products consists primarily of direct labor, allocated manufacturing overhead, raw materials and components. NTIC’s margins on its Natur-Tec^® resin compounds and finished products are generally smaller than its margins on its ZERUST^® products and services, and NTIC’s margins on its ZERUST^® products and services sold into the oil and gas industry are generally greater than its margins on its traditional ZERUST^® products and services.

Equity in Income from Joint Ventures. NTIC’s equity in income from joint ventures consists of NTIC’s share of equity in income from itseach joint venturesventure based on the overall profitability of the joint ventures. Such profitability is subject to variability from quarter to quarter which, in turn, subjects NTIC’s earnings to variability from quarter to quarter. Traditionally, a portion of the equity income recorded in a given fiscal year is paid to the owners of the joint venture entity during the following fiscal year through a dividend. The payment of a dividend by a joint venture entity is determined by a vote of the joint venture owners and is not at the sole discretion of NTIC. NTIC typically owns only 50% or less of its joint venture entities and thus does not control the decisions of these entities regarding whether to pay dividends and, if paid, how much they should be in a given year.

Fees for Services Provided Toto Joint Ventures. NTIC provides certain services to its joint ventures including consulting, legal, travel, insurance, technical and marketing services. NTIC receives fees for these services it provides to its joint ventures based primarily on the net sales by NTIC’s joint ventures, the latter of which are not included in NTIC’s net sales reflected on NTIC’s consolidated statements of operations. The fees for services received by NTIC from its joint ventures are generally determined based on either a flat fee or a percentage of net sales by NTIC’s joint ventures depending on local laws and tax regulations. With respect to EXCOR, NTIC receives an agreed upon fixed quarterly fee for such services. NTIC records revenue related to fees for services provided to joint ventures when earned, amounts are determinable, and collectability is reasonably assured. Under NTIC’s agreements with its joint ventures in which the fees for services is described, fees are earned when the joint venture recognizes the revenue.

NTIC sponsors a worldwide joint venture conference periodically in which all of NTIC’s joint ventures are invited to participate. It is anticipated that the next joint venture conference will be held next year or the year thereafter. NTIC defers a portion of its fees for services provided to joint ventures in each accounting period leading up to the next conference, reflecting that NTIC has not fully earned the payments received during that period. The amount deferred is based on the historical experience of NTIC, current conditions and the intentions of NTIC’s management. The costs associated with these joint venture conferences are offset against the deferral as incurred, generally in the period in which the conference is held and immediately before.

Selling Expenses. Selling expenses consist primarily of sales commissions and support costs for NTIC’s direct sale and distribution system, and marketing costs.

General and Administrative Expenses. General and administrative expenses consist primarily of salaries and benefits, and other costs for NTIC’s executives, accounting, stock-based compensation, finance, legal, information technology and human resources functions.

Expenses Incurred in Support of Joint Ventures. NTIC incurs direct expenses related to its joint ventures and in connection with NTIC’s provision of support and services to its joint ventures. Such expenses include items such as employee compensation and benefits, travel, consulting, legal and laboratory supplies and testing expenses.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

NTIC makes this determination based on all available evidence, including historical data and projections of future results. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities.
