NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. | INTERIM FINANCIAL INFORMATION

In the opinion of management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, which are of a normal recurring nature, and present fairly the consolidated financial position of Northern Technologies International Corporation and its subsidiaries (the Company) as of May 31, 2013 and August 31, 2012 and the results of their operations for the three and nine months ended May 31, 2013 and 2012 and their cash flows for the nine months ended May 31, 2013 and 2012, in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP).
Certain amounts reported in the consolidated financial statements for the previous reporting periods have been reclassified to conform to the current period presentation. These reclassifications did not have a material impact on the Company’s previously reported consolidated balance sheets or statements of cash flows.
These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s annual report on Form 10-K for the fiscal year ended August 31, 2012. These consolidated financial statements also should be read in conjunction with the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section appearing in this report.
Operating results for the three and nine months ended May 31, 2013 are not necessarily indicative of the results that may be expected for the full fiscal year ending August 31, 2013.
The Company evaluates events occurring after the date of the consolidated financial statements requiring recording or disclosure in the consolidated financial statements.

2. | NTI ASEAN

NTI Asean LLC (NTI Asean) is an entity that holds investments in eight entities operating in the Association of Southeast Asian Nations (ASEAN) region, including the following countries: China, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand.
Prior to September 1, 2012, the Company owned 50% of NTI Asean, which it considered to be less than a majority, of the equity and voting rights and accounted for its investment using the equity method. On September 1, 2012, the Company obtained an additional 10% ownership interest in NTI Asean in exchange for a license agreement, and thereafter holds 60% of the equity and voting rights of NTI Asean.
The Company accounted for the transaction resulting in the additional ownership as a business combination. Beginning in the first quarter of fiscal 2013, the Company consolidated the results of NTI Asean. Immediately prior to the transaction, the Company re-measured the fair value of NTI Asean and determined that there was no difference between the fair value and the book value of the entity. As a result, there was no accounting impact related to the business combination in the consolidated statements of operations.
The Company determined the fair value of NTI Asean using the capitalized income method, including a capitalization rate of 25%. The allocation of the total transaction amount was as follow:

Net assets acquired (liabilities assumed): |  |  |
Cash and cash equivalents |  | $ | 1,613,000 |
Accounts receivables |  |  | 1,342,000 |
Investments in joint ventures |  |  | 4,967,000 |
Value of assets |  | $ | 7,922,000 |

Purchase price: |  |  |  |
Fair value of non-controlling interest |  | $ | 3,961,000 |
Value of previously held interest |  |  | 3,961,000 |

The expenses include items such as employee compensation and benefit expenses, travel expense and consulting expense.
The Company did not make any joint venture investments during the nine months ended May 31, 2013 and 2012.

7. | CORPORATE DEBT

As of May 31, 2013, Northern Technologies Holding Company, LLC (NTI LLC) had a term loan with a principal amount of $952,444 outstanding that NTI LLC obtained from PNC Bank, National Association (PNC Bank) in connection with the purchase of NTIC’s corporate headquarters in September 2006. The term loan matures on January 10, 2016, bears interest at an annual rate based on the daily LIBOR rate plus 2.15% and is payable in consecutive monthly installments equal to approximately $6,343 (inclusive of principal but exclusive of interest). The term loan is secured by a first lien on the real estate and building owned by NTI LLC and all of the assets of the Company and is guaranteed by the Company.
The Company has a revolving line of credit with PNC Bank of $3,000,000. No amounts were outstanding under the line of credit as of May 31, 2013 and August 31, 2012. At the option of the Company, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by the Company or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate. Interest is payable in arrears (a) for the portion of advances bearing interest under the prime rate on the last day of each month during the term thereof and (b) for the portion of advances bearing interest under the LIBOR option on the last day of the respective LIBOR interest period selected for such advance. Any unpaid interest is payable on the maturity date. As of May 31, 2013, the interest rate was 2.85% and the weighted average rate was 3.02% for the nine months ended May 31, 2013. As of May 31, 2012, the interest rate was 3.20% and the weighted average rate was 3.16% for the nine months ended May 31, 2012. The revolving line of credit is secured by cash, receivables and inventory.
10

The term loan and the line of credit are governed under separate loan agreements (collectively, the Loan Agreements). The Loan Agreements contain standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the Loan Agreements, the Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00. As of May 31, 2013, the Company was in compliance with all debt covenants.
On December 11, 2012, PNC Bank extended the maturity date of the line of credit from January 9, 2013 to January 8, 2014, and waived a technical covenant default by the Company to deliver quarterly compliance certificates. All other terms of the line of credit and the loan agreement and other documents evidencing the line of credit remain the same. It is anticipated that the line of credit will be extended again prior to the January 8, 2014 maturity date.

During the nine months ended May 31, 2012, the Company issued stock bonuses under the 2007 Plan for an aggregate of 42,707 shares of its common stock to various employees at a grant price of $14.42 per share. The aggregate fair value of the shares of the Company’s common stock as of the date of payment of the stock bonuses was $615,830, based on the closing sale price of a share of the Company’s common stock on the date of payment. The fair value of common stock granted during the nine months ended May 31, 2012 was based on fiscal 2012 performance and was included in accrued liabilities at August 31, 2012.

9. | NET INCOME PER COMMON SHARE

Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share assumes the exercise of stock options using the treasury stock method, if dilutive.
Options to purchase shares of common stock of 40,000 were excluded from the computation of common share equivalents for the three and nine months ended May 31, 2013, as the exercise prices of such options were greater than market price of a share of common stock. Options to purchase shares of common stock of 26,000 were excluded from the computation of common share equivalents for the three and nine months ended May 31, 2012, as the exercise prices of such options were greater than market price of a share of common stock.
The following is a reconciliation of the earnings per share computation for the three and nine months ended May 31, 2013 and 2012:

|  | Three Months Ended |  |  | Nine Months Ended |
Numerators: |  | May 31, 2013 |  |  | May 31, 2012 |  |  | May 31, 2013 |  | May 31, 2012 |
Net income attributable to NTIC |  | $ | 927,112 |  |  | $ | 1,454,037 |  |  | $ | 1,751,144 |  |  | $ | 3,018,987 |
Denominator: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Basic – weighted shares outstanding |  |  | 4,421,379 |  |  |  | 4,399,290 |  |  |  | 4,415,452 |  |  |  | 4,379,175 |
Weighted shares assumed upon exercise of stock options |  |  | 47,482 |  |  |  | 61,754 |  |  |  | 49,322 |  |  |  | 65,297 |
Diluted – weighted shares outstanding |  |  | 4,468,861 |  |  |  | 4,461,044 |  |  |  | 4,464,774 |  |  |  | 4,448,472 |
Basic earnings per share: |  | $ | 0.21 |  |  | $ | 0.33 |  |  | $ | 0.40 |  |  | $ | 0.69 |
Diluted earnings per share: |  | $ | 0.21 |  |  | $ | 0.33 |  |  | $ | 0.39 |  |  | $ | 0.68 |

The dilutive impact summarized above relates to the periods when the average market price of the Company’s common stock exceeded the exercise price of the potentially dilutive option securities granted. Earnings per common share were based on the weighted average number of common shares outstanding during the periods when computing the basic earnings per share. When dilutive, stock options are included as equivalents using the treasury stock market method when computing the diluted earnings per share.

10. | STOCK-BASED COMPENSATION

The Company has two stock-based compensation plans under which stock options and other stock-based awards have been granted, including the Northern Technologies International Corporation Amended and Restated 2007 Stock Incentive Plan and the Northern Technologies International Corporation Employee Stock Purchase Plan (the ESPP). The Compensation Committee of the Board of Directors and the Board of Directors administers these plans.
12

The 2007 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses to eligible recipients to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation in the Company, and to reward those individuals who contribute to the achievement of the Company’s economic objectives. Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company’s common stock are issuable under the 2007 Plan. Options granted under the 2007 Plan generally have a term of five years and become exercisable over a three- or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company’s common stock on the date of grant. To date, only stock options and stock bonuses have been granted under the 2007 Plan.
The maximum number of shares of common stock of the Company available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting purposes.
The Company granted options to purchase an aggregate of 118,294 and 26,000 shares of its common stock during the nine months ended May 31, 2013 and 2012, respectively. The fair value of option grants is determined at date of grant, using the Black-Scholes option pricing model with the assumptions listed below. Based on these valuations, the Company recognized compensation expense of $213,374 and $216,712 during the nine months ended May 31, 2013 and 2012, respectively, related to the options that vested during such time period. The stock-based expense recorded reduced after-tax net income per share by $0.05 for each of the nine months ended May 31, 2013 and 2012. As of May 31, 2013, the total compensation cost for non-vested options not yet recognized in the Company’s consolidated statements of operations was $398,849 net of estimated forfeitures. Additional stock-based compensation expense of $93,077 is expected through the remainder of fiscal year 2013, and expense of $185,815 and $99,964 is expected to be recognized during fiscal 2014 and fiscal 2015, respectively. Future option grants will impact the compensation expense recognized.
The Company currently estimates a ten percent forfeiture rate for stock options and continually reviews this estimate for future periods.
The fair value of each option grant is estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions and results for the grants:

|  | May 31, |
|  | 2013 |  | 2012 |
| Dividend yield |  |  | 0.00% |  | 0.00% |
| Expected volatility |  |  | 48.0% |  | 48.8% |
| Expected life of option (years) | 5 | - | 10 |  | 5 |
| Average risk-free interest rate |  |  | 0.71% |  | 1.31% |

The weighted average per share fair value of options granted during nine months ended May 31, 2013 and 2012 was $5.53 and $7.14, respectively. The weighted average remaining contractual life of the options outstanding as of May 31, 2013 and 2012 was 4.48 years and 1.82 years, respectively.

ITEM 2. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis provides material historical and prospective disclosures intended to enable investors and other users to assess NTIC’s financial condition and results of operations. Statements that are not historical are forward-looking and involve risks and uncertainties discussed under the heading “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Forward-Looking Statements.” The following discussion of the results of the operations and financial condition of NTIC should be read in conjunction with NTIC’s consolidated financial statements and the related notes thereto included under the heading “Part I. Item 1. Financial Statements.”
Business Overview
NTIC develops and markets proprietary environmentally beneficial products and services in over 55 countries either directly or via a network of majority owned 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® rust and corrosion inhibiting products and services to the automotive, electronics, electrical, mechanical, military and retail consumer markets for over 35 years, and more recently, has targeted and expanded into the oil and gas industry. NTIC also sells a portfolio of bio-based and biodegradable (compostable) polymer resin compounds and finished products marketed under the Natur-Tec® brand. These products are intended to reduce NTIC’s customers’ carbon footprint and provide environmentally sound disposal options.
NTIC’s ZERUST® rust and corrosion inhibiting products include plastic and paper packaging, liquids and coatings, rust removers and cleaners, diffusers and variations of these products designed specifically for the oil and gas industry. NTIC’s 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® rust and corrosion inhibiting products to analyze their specific needs and develop systems to meet their technical requirements. In North America, NTIC sells its ZERUST® corrosion prevention solutions through a direct sales force as well as a network of independent distributors and agents. Internationally, NTIC sells its ZERUST® corrosion prevention solutions through its majority owned Brazilian subsidiary, 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 Asian LLC (NTI Asean), and joint venture arrangements in North America and Europe.
One of NTIC’s strategic initiatives is to expand into and penetrate other markets for its ZERUST® corrosion prevention solutions. For the past several years, NTIC has focused its sales and marketing efforts on the oil and gas industry since the infrastructure that supports that industry is typically constructed using metals that are highly susceptible to corrosion and NTIC believes that its 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.
Petroleo Brasileiro S.A. (Petrobras), an oil company located in Brazil, has conducted extensive multi-year product field trials of NTIC’s ZERUST® rust and corrosion inhibiting products against competitive alternatives. During fiscal 2010, Zerust Brazil received a Phase 1 contract for an initial implementation of $1.4 million in ZERUST® products which was delivered in fiscal 2010 and fiscal 2011. During fiscal 2011, Zerust Brazil signed a Phase 2 contract with Petrobras to supply $2.4 million in ZERUST® products. During fiscal 2012, Petrobras expanded this Phase 2 contract to supply an additional $657,000 in ZERUST® products, bringing the total Phase 2 contract value to $3.1 million in ZERUST® products, which were delivered in fiscal 2012. During first quarter of fiscal 2013, Zerust Brazil signed a Phase 3 contract with Petrobras to supply $3.7 million in ZERUST® products, none of which had been delivered through the end of third quarter of fiscal 2013. While NTIC initially had anticipated that Petrobras would fulfill this Phase 3 contract in one large order prior to the end of fiscal 2013, based on NTIC’s recent discussions with Petrobras, NTIC believes that Petrobras intends to place a number of smaller orders during the remainder of fiscal 2013 and fiscal 2014, rather than one large order prior to the end of fiscal 2013.
18

NTIC is also pursuing opportunities to market its ZERUST® rust and corrosion prevention solutions to other targeted potential customers in the oil and gas industry across several geographies through NTIC’s joint venture partners as well as other strategic partners. NTIC believes that sales of its ZERUST® corrosion prevention solutions to customers in the oil and gas industry require long sales cycles that include trial periods of at least one year with each customer, followed by a slow integration process thereafter.
Natur-Tec® bio-based and biodegradable plastics are manufactured using NTIC’s patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec® biopolymer resin compound portfolio include formulations that have been optimized for a variety of applications including blown-film extrusion, extrusion coating, injection molding, and engineered plastics. These resin compounds are fully biodegradable in a composting environment and are currently being used to produce finished products including shopping and grocery bags, lawn and leaf bags, can liners, pet waste collection bags, cutlery, packaging foam and coated paper products. In North America, NTIC markets its Natur-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® bioplastic products. Internationally, NTIC sells its Natur-Tec® resin compounds and finished products both directly and through some of its joint ventures.
During fiscal 2012, NTIC’s joint venture in India, Harita NTI Limited (HNTI) entered into an agreement to supply compostable packaging to a major global apparel brand for branded garments. HNTI also continues to pursue bioplastic product sales opportunities in food and personal care industries. During fiscal 2011, NTIC entered into an agreement with Italy-based Naturfuels s.r.l. to distribute its Natur-Tec® bioplastic materials and products in the Italian market. Under the terms of this distribution agreement, NTIC supplies Naturfuels with patented high-strength Natur-Tec® film grade resin compounds suited to producing compostable shopping and garbage bags on conventional plastic film production equipment. In 2011, the Italian government passed legislation banning the use of non-biodegradable disposable plastic shopping bags. However, enforcement of this law, continues to be delayed for a number of reasons including a recent legal challenge as to the validity of the ban in a European Union member country by the government of the United Kingdom. Consequently, significant sales of Natur-Tec® film grade resin compounds to Naturfuels are not expected until whenever the Italian ban is fully implemented and enforced.
NTIC’s Joint Venture Network
NTIC participates in 23 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 sell NTIC’s Natur-Tec® resin compounds. NTIC historically has funded its investments in joint ventures with cash generated from operations.
NTIC’s receipt of funds from its joint ventures is dependent upon fees for services that NTIC provides to its joint ventures, based primarily on the revenues of the joint ventures, and NTIC’s receipt of dividend distributions from the joint ventures. NTIC receives fees for services provided to its joint ventures based primarily on the net sales of the individual joint ventures. The fees for services provided to joint ventures are determined based on either a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to NTIC’s primary joint venture in Germany (EXCOR), NTIC recognizes an agreed upon quarterly fee for such services. NTIC recognizes equity income from its joint ventures based on the overall profitability of its joint ventures. Such profitability is subject to variability from quarter to quarter which, in turn, subjects NTIC’s earnings to variability from quarter to quarter. The profits of NTIC’s joint ventures are shared by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically owns directly or indirectly 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.
19

NTIC does not consolidate the results of its 23 joint ventures in its financial statements. NTIC’s investments in its joint ventures are accounted for using the equity method.
Zerust Brazil’s results are consolidated in NTIC’s consolidated financial statements. NTIC holds 85% of the equity and 85% of the voting rights of Zerust Brazil.
In addition, beginning in the first quarter of fiscal 2013, NTIC has consolidated the results of NTI Asean, which effective as of September 1, 2012 is a majority owned subsidiary of NTIC. On September 1, 2012, NTIC and the other 50% owner in NTI Asean contributed their respective shares of capital stock of Korea Zerust Co., Ltd. (Korea Zerust), constituting an aggregate of 50% of the equity and voting rights of Korea Zerust, to NTI Asean, and NTIC contributed exclusive license rights and other intellectual property to NTI Asean in exchange for an additional 10% ownership interest in NTI Asean. As a result of the transaction, 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, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand.
With respect to NTIC’s joint ventures, NTIC considers EXCOR and China to be individually significant to NTIC’s consolidated assets and income; and therefore, provides certain additional information regarding EXCOR and China in the notes to NTIC’s consolidated financial statements and in this section of this report.
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 decreased 24.7% and 6.8% during the three and nine months ended May 31, 2013, compared to the three and nine months ended May 31, 2012, respectively. These decreases were primarily a result of decreases in sales of ZERUST® rust and corrosion inhibiting packaging products and services in Brazil. Zerust Brazil recorded a $2.3 million order during the three months ended May 31, 2012 related to product sales to Petrobras and did not have any sales to Petrobras during the three months ended May 31, 2013. NTIC believes that Petrobras intends to place a number of smaller orders during the remainder of fiscal 2013 and fiscal 2014, rather than one large order as Petrobras did during the three months ended May 31, 2012.
During the three and nine months ended May 31, 2013, 92.2% and 90.9% of NTIC’s consolidated net sales, respectively, were derived from sales of ZERUST® products and services, which decreased 25.0% and 8.1% to $5,418,271 and $14,923,966 during the three and nine months ended May 31, 2013, respectively, compared to $7,220,258 and $16,243,683 during the three and nine months ended May 31, 2012, respectively, due primarily to decreases in sales of ZERUST® products and services in Brazil as noted above. NTIC has strategically focused its sales efforts for ZERUST® products and services on customers with sizeable corrosion problems in industry sectors that offer sizable growth opportunities, including the oil and gas sector. NTIC’s consolidated net sales for the three and nine months ended May 31, 2013 included $567,615 and $1,699,084, respectively, of sales made by Zerust Brazil, and of those sales, $0 and $189,642, respectively, in sales were made to the oil and gas industry in Brazil. Overall demand for ZERUST® products and services depends heavily on the overall health of the markets in which NTIC sells its products, including in particular the automotive market.
20

During the three and nine months ended May 31, 2013, 7.8% and 9.1%, respectively, of NTIC’s consolidated net sales were derived from sales of Natur-Tec® products compared to 7.5% and 7.8% during the three and nine months ended May 31, 2012, respectively. Net sales of Natur-Tec® products decreased 21.5% during the three months ended May 31, 2013 compared to the three months ended May 31, 2012 due primarily to variable ordering patterns by distributors and sales agents and a distributor change. 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 affect materially NTIC’s quarterly sales of Natur-Tec® products and the comparisons to prior year quarters. Net sales of Natur-Tec® products increased 9.0% during the nine months ended May 31, 2013 compared to the nine months ended May 31, 2012 due primarily to increased sales to NTIC’s Natur-Tec® distributors in the United States. Additionally, NTIC continues to target key regional and national retailers through independent sales agents. Demand for the Natur-Tec® products depends primarily on market acceptance and the reach of NTIC’s distribution network.
Cost of goods sold as a percentage of net sales increased to 69.0% and 69.3% during the three and nine months ended May 31, 2013 compared to 53.1% and 61.5% during the three and nine months ended May 31, 2012 primarily as a result of increased sales during the prior year periods of ZERUST® products for the oil and gas industry which carry higher margins than other ZERUST® products and increased production expenses during the current year periods associated with the production and shipping of ZERUST® products to a new customer. The increase in production expenses is anticipated to be temporary and should normalize during the fourth quarter of fiscal 2013.
NTIC’s equity in income of joint ventures decreased 21.0% and 15.3% to $1,440,335 and $3,733,069, respectively, during the three and nine months ended May 31, 2013 compared to $1,822,972 and $4,405,327 during the three and nine months ended May 31, 2012, respectively. These decreases were primarily a result of the consolidation of NTI Asean which was included in the current fiscal year periods, but not in the prior fiscal year periods.
NTIC recognized a 161.2% and 59.2% increase in fees for services provided to joint ventures during the three and nine months ended May 31, 2013 compared to the three and nine months ended May 31, 2012, respectively. These increases were primarily a result of the consolidation of fees for services earned by NTI Asean which are included in the current fiscal year periods, but not in the prior fiscal year periods. Fees for services provided are a function of the net sales of NTIC’s joint ventures which were $28,541,576 and $82,788,711 during the three and nine months ended May 31, 2013 compared to $28,954,210 and $83,746,872 for the three and nine months ended May 31, 2012, respectively. 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, and the weakening of the EURO and other currencies compared to the U.S. dollar.
NTIC’s total operating expenses increased 4.5%, or $468,106, to $10,966,765 during the nine months ended May 31, 2013 compared to the nine months ended May 31, 2012. This increase was primarily the result of increases in selling expenses and expenses incurred in support of joint ventures, and overall reflected NTIC’s efforts to support its new business efforts.
NTIC expenses all costs related to product research and development as incurred. NTIC incurred $2,853,250 and $2,856,536 of expense during the nine months ended May 31, 2013 and 2012, respectively, in connection with its research and development activities. These represent net amounts after being reduced by reimbursements related to certain research and development contracts. Such reimbursements totaled $206,046 and $297,258 for the nine months ended May 31, 2013 and 2012, respectively. NTIC anticipates that it will spend between $3,800,000 and $4,000,000 in total during fiscal 2013 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.
Net income attributable to NTIC decreased 36.2% to $927,112, or $0.21 per diluted common share, for the three months ended May 31, 2013 compared to $1,454,037, or $0.33 per diluted common share, for the three months ended May 31, 2012. Net income attributable to NTIC decreased 42.0% to $1,751,144, or $0.39 per diluted common share, for the nine months ended May 31, 2013 compared to $3,018,987, or $0.68 per diluted common share, for the nine months ended May 31, 2012. These decreases were primarily the result of decreases in gross profit, partially offset by increases in fees for services provided to joint ventures. NTIC anticipates that its quarterly net income will remain subject to significant volatility primarily due to the sales performance of its joint ventures and sales of its ZERUST® products and services into the oil and gas industry. Each of these fluctuates more on a quarterly basis than the traditional ZERUST® business in North America.
21

NTIC anticipates that its net income attributable to NTIC will be positively affected during fourth quarter of fiscal 2013 as a result of its receipt of $500,000 and anticipated receipt of an additional $250,000 in life insurance proceeds as a result of the death of a former NTIC officer.
NTIC’s working capital was $13,136,534 at May 31, 2013, including $3,176,157 in cash and cash equivalents, compared to $10,060,081 at August 31, 2012, including $4,137,547 in cash and cash equivalents.

Net Sales. NTIC’s consolidated net sales decreased 24.7% and 6.8% to $5,877,033 and $16,415,130 during the three and nine months ended May 31, 2013, respectively, compared to the three and nine months ended May 31, 2012. NTIC’s consolidated net sales excluding NTIC’s joint ventures decreased 29.7% and 8.2% to $5,041,096 and $14,296,686 during the three and nine months ended May 31, 2013, respectively, compared to the same respective prior year periods. These decreases were primarily a result of decreases in sales of ZERUST® rust and corrosion inhibiting packaging products and services in Brazil. Zerust Brazil recorded a $2.3 million order during the three months ended May 31, 2012 related to product sales to Petrobras and did not have any sales to Petrobras during the three months ended May 31, 2013. NTIC believes that Petrobras intends to place a number of smaller orders during the remainder of fiscal 2013 and fiscal 2014, rather than one large order as Petrobras did during the three months ended May 31, 2012. Net sales to joint ventures increased 32.9% and 4.2% to $835,937 and $2,118,444 during the three and nine months ended May 31, 2013, respectively, compared to the same respective prior year periods. The increase for the three month comparison was primarily due to timing differences with orders placed with NTIC’s 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. The increase for the nine month comparison was a function of sales made by the joint ventures.
22

The following table sets forth NTIC’s net sales by product category for the three and nine months ended May 31, 2013 and 2012 by segment:

|  | Three Months Ended |  |  | Nine Months Ended |
|  | May 31, 2013 |  |  | May 31, 2012 |  |  | May 31, 2013 |  |  | May 31, 2012 |
ZERUST® sales |  | $ | 5,418,271 |  |  | $ | 7,220,258 |  |  | $ | 14,923,966 |  |  | $ | 16,243,683 |
Natur-Tec® sales |  |  | 458,762 |  |  |  | 584,646 |  |  |  | 1,491,164 |  |  |  | 1,367,663 |
Total net sales |  | $ | 5,877,033 |  |  | $ | 7,804,904 |  |  | $ | 16,415,130 |  |  | $ | 17,611,346 |

During the three and nine months ended May 31, 2013, 92.2% and 90.9% of NTIC’s consolidated net sales, respectively, were derived from sales of ZERUST® products and services, which decreased 25.0% and 8.1% to $5,418,271 and $14,923,966 during the three and nine months ended May 31, 2013, respectively, compared to $7,220,258 and $16,243,683 during the three and nine months ended May 31, 2012, respectively. These decreases were due primarily to decreases in sales of ZERUST® products and services in Brazil as noted above. NTIC has strategically focused its sales efforts for ZERUST® products and services on customers with sizeable corrosion problems in industry sectors that offer sizable growth opportunities, including the oil and gas sector.
During the three and nine months ended May 31, 2013, 7.8% and 9.1%, respectively, of NTIC’s consolidated net sales were derived from sales of Natur-Tec® products compared to 7.5% and 7.8% during the three and nine months ended May 31, 2012, respectively. Net sales of Natur-Tec® products decreased 21.5% during the three months ended May 31, 2013 compared to the three months ended May 31, 2012 due primarily to variable ordering patterns by distributors and sales agents and a distributor change. 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 affect materially NTIC’s quarterly sales of Natur-Tec® products and the comparisons to prior year quarters. Net sales of Natur-Tec® products increased 9.0% during the nine months ended May 31, 2013 compared to the nine months ended May 31, 2012 due primarily to increased sales to NTIC’s Natur-Tec® distributors in the United States. Additionally, NTIC continues to target key regional and national retailers through independent sales agents. Demand for the Natur-Tec® products depends primarily on market acceptance and the reach of NTIC’s distribution network
Cost of Goods Sold. Cost of goods sold decreased 2.2% and increased 5.0% for the three and nine months ended May 31, 2013, respectively, compared to the three and nine months ended May 31, 2012. Cost of goods sold as a percentage of net sales increased to 69.0% and 69.3% during the three and nine months ended May 31, 2013 compared to 53.1% and 61.5% during the three and nine months ended May 31, 2012 primarily as a result of increased sales during the prior year periods of ZERUST® products for the oil and gas industry which carry higher margins than other traditional ZERUST® products and increased production expenses during the current year periods associated with the production and shipping of ZERUST® products to a new customer. The increase in production expenses is anticipated to be temporary and should normalize during the fourth quarter of fiscal 2013.
Equity in Income of Joint Ventures. NTIC’s equity in income of joint ventures decreased 21.0% and 15.3% to $1,440,335 and $3,733,069 during the three and nine months ended May 31, 2013, respectively, compared to equity in income of joint ventures of $1,822,972 and $4,405,327 during the three and nine months ended May 31, 2012, respectively. These decreases were primarily a result of the consolidation of NTI Asean in the current fiscal year periods, but not in the prior fiscal year periods. Of the total equity in income of joint ventures, NTIC had equity in income of joint ventures of $2,478,109 attributable to EXCOR during the nine months ended May 31, 2013 compared to $2,396,596 attributable to EXCOR during the nine months ended May 31, 2012. Of the total equity in income of joint ventures, NTIC had equity in income of joint ventures of $407,809 attributable to NTIC’s joint venture in China during the nine months ended May 31, 2013 compared to $356,963 attributable to NTIC’s joint venture in China during the nine months ended May 31, 2012. NTIC had equity in income of all other joint ventures of $847,151 during the nine months ended May 31, 2013 compared to $1,652,038 during the nine months ended May 31, 2012.
23

Fees for Services Provided to Joint Ventures. NTIC recognized fee income for services provided to joint ventures of $1,917,947 and $5,535,105 during the three and nine months ended May 31, 2013, respectively, compared to $734,337 and $3,477,715 during the three and nine months ended May 31, 2012, respectively, representing an increase of 161.2% and 59.2%, respectively. These increases were primarily a result of the consolidation of the fees for services earned by NTI Asean which are included in the current fiscal year periods, but not in the prior fiscal year periods. Fee income for services provided to joint ventures are a function of the sales made by NTIC’s joint ventures, which were $28,541,576 and $82,788,711 during the three and nine months ended May 31, 2013, respectively, compared to $28,954,210 and $83,746,872 for the three and nine months ended May 31, 2012, respectively. Total net sales of NTIC’s joint ventures were adversely affected in part by the European economic slowdown, which NTIC believes also adversely affected net sales of certain of NTIC’s other non-European joint ventures, as well as the weakening of the EURO and other currencies compared to the U.S. dollar. Sales of NTIC’s joint ventures are not included in NTIC’s product sales and are not combined with NTIC’s sales in NTIC’s consolidated financial statements or in any description of NTIC’s sales.
Of the total fee income for services provided to joint ventures, fees of $742,212 were attributable to EXCOR during the nine months ended May 31, 2013 compared to $742,170 attributable to EXCOR during the nine months ended May 31, 2012. Fees of $1,468,622 were attributable to NTIC’s joint venture in China during the nine months ended May 31, 2013 compared to $0 during the nine months ended May 31, 2012, as a result of the consolidation of NTI Asean in the current fiscal year periods, but not in the prior fiscal year periods.
Selling Expenses. NTIC’s selling expenses decreased 2.1% and increased 5.8% for the three and nine months ended May 31, 2013 compared to the same respective periods in fiscal 2012. The increase for the nine month comparison was due primarily to increases in compensation and employee benefits, lab testing related expenses, commission expenses, travel and related expenses, and consulting expenses and selling expenses incurred at Zerust Brazil. Selling expenses as a percentage of net sales increased to 21.1% and 21.9% for the three and nine months ended May 31, 2013, respectively, from 16.3% and 19.3% during the three and nine months ended May 31, 2012, respectively, due primarily to the decrease in net sales and for the nine month comparison the increase in selling expenses, as previously described.
General and Administrative Expenses. NTIC’s general and administrative expenses decreased 3.7% and 0.6% for the three and nine months ended May 31, 2013, respectively, compared to the same respective periods in fiscal 2012 due to decreases in consulting and employee expenses. As a percentage of net sales, general and administrative expenses increased to 18.8% and 21.3% for the three and nine months ended May 31, 2013 from 14.7% and 20.0% for the three and nine months ended May 31, 2012, respectively, due primarily to the decrease in net sales, partially offset by the decrease in general and administrative expenses, as previously described.
Expenses Incurred in Support of Joint Ventures. Expenses incurred in support of NTIC’s joint ventures were $335,132 and $1,026,275 during the three and nine months ended May 31, 2013, respectively, compared to $294,169 and $729,990 during the three and nine months ended May 31, 2012, respectively, representing increases of 13.9% and 40.6%, respectively.
Research and Development Expenses. NTIC’s research and development expenses decreased 6.1% for the three months ended May 31, 2013 compared to the same period in fiscal 2012 and decreased 0.1% for the nine months ended May 31, 2013 compared to the same period in fiscal 2012.
24

Interest Income. NTIC’s interest income decreased to $2,984 and increased to $50,618 during the three and nine months ended May 31, 2013, respectively, compared to $15,726 and $36,417 during the three and nine months ended May 31, 2012, respectively, primarily due to changes in cash balances of Zerust Brazil and NTI Asean earning interest.
Interest Expense. NTIC’s interest expense increased to $50,986 during the three months ended May 31, 2013 compared to $6,264 during the three months ended May 31, 2012. NTIC’s interest expense increased to $64,448 during the nine months ended May 31, 2013 compared to $19,514 during the nine months ended May 31, 2012. Such increases were primarily due to increased average outstanding debt levels of Zerust Brazil during the most recent periods.
Income Before Income Tax Expense. Income before income tax expense decreased to $1,445,769 and $3,232,460 for the three and nine months ended May 31, 2013, respectively, compared to $2,454,623 and $4,200,035 for the three and nine months ended May 31, 2012, respectively.
Income Tax Expense. Income tax expense was $158,000 and $532,000 during the three and nine months ended May 31, 2013, respectively, compared $814,000 and $1,020,000 during the three and nine months ended May 31, 2012, respectively, due primarily to the decrease in income before income tax expense during the current year periods. Income tax expense was calculated based on management’s estimate of NTIC’s annual effective income tax rate. NTIC’s annual effective income tax rate during the three and nine months ended May 31, 2013 and 2012 was lower than the statutory rate primarily due to NTIC’s equity in income of joint ventures being recognized based on after-tax earnings of these entities. To the extent undistributed earnings of NTIC’s joint ventures are distributed to NTIC, it is not expected to result in any material additional income tax liability after the application of foreign tax credits. NTIC records a tax valuation allowance when it is more likely than not that some portion or all of its deferred tax assets will not be realized to reduce deferred tax assets to the amount expected to be realized. NTIC determined based on all available evidence, including historical data and projections of future results, that it is more likely than not that all of its deferred tax assets, except for its foreign tax credit carryforwards and Minnesota state research and development credit carryforwards, will be fully realized. In addition, NTIC determined based upon all available evidence, including new IRS guidance, historical results, projected future taxable income and foreign tax credit utilization, that it was not more likely than not that the federal research and development credits would be utilized during the carryforward period and as a result, a valuation allowance was recorded against all of NTIC’s federal research and development credits. In addition, NTIC continues to believe that its deferred tax asset related to foreign tax credit carryforwards will not be realized due to insufficient federal taxable income within the carryforward period and the fact that for ordering purposes the foreign tax credit carryforwards are not allowed to be used until after any current year foreign tax credits are utilized.
NTIC considers the earnings of certain foreign joint ventures to be indefinitely invested outside the United States on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs. As a result, U.S. income and foreign withholding taxes have not been recognized on the cumulative undistributed earnings of $20.9 million and $19.4 million at May 31, 2013 and August 31, 2012, respectively. To the extent undistributed earnings of NTIC’s joint ventures are distributed in the future, they are not expected to result in any material additional income tax liability after the application of foreign tax credits
Other Comprehensive Income - Foreign Currency Translations Adjustment. The volatility of the foreign currency translations adjustment was due to the volatility of the U.S. dollar compared to the Euro and other foreign currencies during the three and nine months ended May 31, 2013 compared to the same respective periods in fiscal 2012.

Liquidity and Capital Resources
Sources of Cash and Working Capital. As of May 31, 2013, NTIC’s working capital was $13,304,534, including $3,176,157 in cash and cash equivalents, compared to working capital of $10,060,081, including $4,137,547 in cash and cash equivalents, at August 31, 2012.
As of May 31, 2013, NTIC had a term loan with a principal amount of $952,444 outstanding that Northern Technologies Holding Company, LLC (NTI LLC) obtained from PNC Bank, National Association (PNC Bank) in connection with the purchase of NTIC’s corporate headquarters in September 2006. The term loan matures on January 10, 2016, bears interest at an annual rate based on the daily LIBOR rate plus 2.15% and is payable in consecutive monthly installments equal to $6,343 (inclusive of principal but exclusive of interest). The term loan is secured by a first lien on the real estate and building owned by NTI LLC and all of the assets of NTIC and is guaranteed by NTIC.
As of May 31, 2013, NTIC also had a revolving line of credit with PNC Bank of $3,000,000 with no amounts outstanding as of such date. The line of credit is evidenced by an amended and restated committed line of credit note in the principal amount of up to $3,000,000. The line of credit has a $1,200,000 standby letter of credit subfacility, with any standby letters of credit issued thereunder being at the sole discretion of PNC Bank. Any standby letters of credit issued under the subfacility are subject to customary fees and charges payable by NTIC. At the option of NTIC, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate. Interest is payable in arrears (a) for the portion of advances bearing interest under the prime rate on the last day of each month during the term thereof and (b) for the portion of advances bearing interest under the LIBOR option on the last day of the respective LIBOR interest period selected for such advance. Any unpaid interest is payable on the maturity date. As of May 31, 2013, the interest rate on the line of credit was 2.85%.
The term loan and the line of credit are governed under two separate loan agreements. The loan agreements contain standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the loan agreements, NTIC is subject to a minimum fixed charge coverage ratio of 1.10:1.00.
On December 11, 2012, PNC Bank extended the maturity date of the line of credit from January 9, 2013 to January 8, 2014 and waived a technical covenant default by NTIC to deliver quarterly compliance certificates. All other terms of the line of credit and the loan agreement and other documents evidencing the line of credit remain the same. NTIC expects to remain in compliance with all loan agreement covenants during the remainder of fiscal 2013. It is anticipated that the maturity date of the line of credit will be extended again prior to the January 8, 2014 maturity date.
NTIC believes that a combination of its existing cash and cash equivalents, forecasted cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC for services provided to its joint ventures, and funds available through existing or anticipated financing arrangements, will be adequate to fund its existing operations, investments in new or existing joint ventures, capital expenditures, debt repayments and any stock repurchases for at least the next 12 months. During the remainder of fiscal 2013, NTIC expects to continue to invest in research and development and in marketing efforts and resources into the application of its corrosion prevention technology into the oil and gas industry and its Natur-Tec® bio-plastics business. In order to take advantage of such new product and market opportunities to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing under its revolving line of credit or raising additional financing through the issuance of debt or equity securities. There is no assurance that any financing transaction will be available on terms acceptable to NTIC or at all, or that any financing transaction will not be dilutive to NTIC’s current stockholders.
26

NTIC traditionally has used the cash generated from its operations, distributions of earnings and fees for services provided to its joint ventures to fund NTIC’s new technology investments and capital contributions to new and existing joint ventures. NTIC’s joint ventures traditionally have operated with little or no debt and have been self-financed with minimal initial capital investment and minimal additional capital investment from their respective owners. Therefore, NTIC believes it is not likely that there exists any exposure to debt by NTIC’s joint ventures that could materially impact NTIC’s or the joint ventures’ respective operations and/or liquidity.
Uses of Cash and Cash Flows. Net cash used in operating activities during the nine months ended May 31, 2013 was $3,052,892, which resulted principally from NTIC’s equity in income from joint ventures and increases in receivables and inventories and a decrease in accounts payables, accrued liabilities and income taxes payable, partially offset by NTIC’s net income, depreciation and amortization. Net cash used in operating activities during the nine months ended May 31, 2012 was $1,172,924 which resulted principally from NTIC’s equity in income from joint ventures and increases in receivables, inventories and prepaid expenses and a decrease in accounts payables, accrued liabilities and income taxes payable, partially offset by NTIC’s net income, depreciation and amortization.
NTIC’s cash flows from operations are impacted by significant changes in certain components of NTIC’s working capital, including inventory turnover and changes in receivables. NTIC considers internal and external factors when assessing the use of its available working capital, specifically when determining inventory levels and credit terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts and customer requested payment terms, and key external factors include the availability of primary raw materials and sub-contractor production lead times. NTIC’s typical contractual terms for trade receivables excluding joint ventures are traditionally 30 days and for trade receivables from its joint ventures are 90 days. Before extending unsecured credit to customers, excluding NTIC’s joint ventures, NTIC reviews customers’ credit histories and will establish an allowance for uncollectible accounts based upon factors surrounding the credit risk of specific customers and other information. Accounts receivable over 30 days are considered past due for most customers. NTIC does not accrue interest on past due accounts receivable. If accounts receivables in excess of the provided allowance are determined uncollectible, they are charged to selling expense in the period that determination is made. Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC’s typical contractual terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services provided to its joint ventures on an accrual basis, unless circumstances exist that make the collection of the balance uncertain in which case the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled on a case by case basis.
NTIC experienced an increase in receivables and inventory as of May 31, 2013 compared to August 31, 2012 due primarily to an increase in net sales to joint ventures and in fees for services provided to joint ventures as previously described and a desire to stock more products to shorten lead times and anticipate customer demand.
Outstanding trade receivables excluding joint ventures as of May 31, 2013 increased $284,527 compared to August 31, 2012. Outstanding trade receivables excluding joint ventures balances as of May 31, 2013 increased 1 day to an average of 51 days from balances outstanding from these customers as of August 31, 2012.
Outstanding trade receivables from joint ventures as of May 31, 2013 increased $385,542 compared to August 31, 2012 primarily due to an increase in net sales to joint ventures and the timing of payments. There was a decrease of outstanding balances from trade receivables from joint ventures as of May 31, 2013 of 6 days from an average of 130 days from balances outstanding from these customers compared to August 31, 2012. The significant average days outstanding of trade receivables from joint ventures as of May 31, 2013 were primarily due to the receivable balance at NTIC’s joint ventures in India, Korea and China.
27

Outstanding receivables for fees for services provided to joint ventures as of May 31, 2013 increased $1,142,554 compared to August 31, 2012 primarily due to the increase in fees for services provided to joint ventures and the consolidation of NTI Asean, which resulted in an increase of 12 days of fees receivable outstanding as of May 31, 2013 to an average of 118 days compared to August 31, 2012.
Net cash provided by investing activities for the nine months ended May 31, 2013 was $3,302,358, which was comprised of dividends received from joint ventures and the effect of the NTI Asean consolidation on cash, partially offset by additions to property and equipment and additions to patents. Net cash provided by investing activities for the nine months ended May 31, 2012 was $2,517,369 which was comprised of dividends received from joint ventures, partially offset by additions to property and equipment and additions to patents.
Net cash used in financing activities for the nine months ended May 31, 2013 was $1,196,170, which resulted from a dividend received from non-controlling interest and principal payments on the bank loan for NTIC’s corporate headquarters building, partially offset by proceeds from option exercises and NTIC’s employee stock purchase plan. Net cash provided by financing activities for the nine months ended May 31, 2012 was $13,361, which resulted from proceeds from NTIC’s employee stock purchase plan, and, to a lesser extent, option exercises, partially offset by principal payments on the bank loan for NTIC’s corporate headquarters building.
Capital Expenditures and Commitments. NTIC had no material lease or other material capital commitments as of May 31, 2013, except a lease agreement for 16,994 square feet of office, manufacturing, laboratory and warehouse space in Beachwood, Ohio, requiring monthly payments of $17,500, which are adjusted annually according to the annual consumer price index, through November 2014.
NTIC spent $1,160,344 on capital expenditures during the nine months ended May 31, 2013 and expects to spend an aggregate of approximately $1,200,000 to $1,300,000 on capital expenditures during fiscal 2013. Such anticipated capital expenditures for fiscal 2013 relate primarily to the expansion of NTIC’s laboratory facilities in Circle Pines, Minnesota and the purchase of new equipment.
Off-Balance Sheet Arrangements
NTIC does not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet financial arrangements. As such, NTIC is not materially exposed to any financing, liquidity, market or credit risk that could arise if NTIC had engaged in such arrangements.
Inflation and Seasonality
Inflation in the U.S. and abroad historically has had little effect on NTIC. NTIC’s business has not historically been seasonal.
Market Risk
NTIC is exposed to some market risk stemming from changes in foreign currency exchange rates, commodity prices and interest rates.
Because the functional currency of NTIC’s foreign operations and investments in its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from transactions in the normal course of business. NTIC’s principal exchange rate exposure is with the Euro, the Japanese yen, Indian Rupee, Chinese yuan, Korean won and the English pound against the U.S. dollar. NTIC’s fees for services provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations in foreign currency exchange rates could result in declines in NTIC’s reported net income. Since NTIC’s investments in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected as a foreign currency translation adjustment and would not change NTIC’s equity in income of joint ventures reflected in its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.
28

Some raw materials used in NTIC’s products are exposed to commodity price changes. The primary commodity price exposures are with a variety of plastic resins.
At the option of NTIC, outstanding advances under NTIC’s $3,000,000 revolving line of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate, and thus may subject NTIC to some market risk on interest rates. As of May 31, 2013, NTIC had no borrowings under the line of credit.
Critical Accounting Policies and Estimates
There have been no material changes to NTIC’s critical accounting policies and estimates from the information provided in “Part II. Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies”, included in NTIC’s annual report on Form 10-K for the fiscal year ended August 31, 2012, except for the following:
Principles of Consolidation
NTIC evaluates its voting and variable interests in entities on a qualitative and quantitative basis. NTIC consolidates entities in which it concludes it has the power to direct the activities that most significantly impact an entity’s economic success and has the obligation to absorb losses or the right to receive benefits that could be significant to the entity. All such relationships are evaluated on an ongoing basis. The consolidated financial statements include the accounts of Northern Technologies International Corporation, its wholly owned subsidiaries, NTI Facilities, Inc., Northern Technologies Holding Company, LLC and NTIC’s majority owned subsidiary in Brazil, Zerust Prevenção de Corrosão S.A., and NTIC’s majority owned holding company, NTI Asean LLC. NTIC’s consolidated financial statements do not include the accounts of any of its joint ventures. NTIC’s consolidated financial statements do not include Polymer Energy LLC, in which NTIC holds a 62.5% ownership interest. Polymer Energy LLC had immaterial activity in fiscal 2013 and fiscal 2012.
Forward-Looking Statements
This quarterly report on Form 10-Q contains not only historical information, but also forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and are subject to the safe harbor created by those sections. In addition, NTIC or others on NTIC’s behalf may make forward-looking statements from time to time in oral presentations, including telephone conferences and/or web casts open to the public, in press releases or reports, on NTIC’s Internet web site or otherwise. All statements other than statements of historical facts included in this report or expressed by NTIC orally from time to time that address activities, events or developments that NTIC expects, believes or anticipates will or may occur in the future are forward-looking statements including, in particular, the statements about NTIC’s plans, objectives, strategies, the outcome of contingencies such as legal proceedings, and prospects regarding, among other things, NTIC’s financial condition, results of operations and business. NTIC has identified some of these forward-looking statements in this report with words like “believe,” “may,” “could,” “would,” “might,” “forecast,” “possible,” “potential,” “project,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate,” “approximate” “outlook” or “continue” or the negative of these words or other words and terms of similar meaning. The use of future dates is also an indication of a forward-looking statement. Forward-looking statements may be contained in the notes to NTIC’s consolidated financial statements and elsewhere in this report, including under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
29

Forward-looking statements are based on current expectations about future events affecting NTIC and are subject to uncertainties and factors that affect all businesses operating in a global market as well as matters specific to NTIC. These uncertainties and factors are difficult to predict and many of them are beyond NTIC’s control. The following are some of the uncertainties and factors known to us that could cause NTIC’s actual results to differ materially from what NTIC has anticipated in its forward-looking statements:

· | The effect of current worldwide economic conditions, the European sovereign debt crisis and turmoil and disruption in the global credit and financial markets on NTIC’s business;

· | The health of the U.S. automotive industry on NTIC’s business;

· | NTIC’s dependence on the success of its joint ventures and fees and dividend distributions that NTIC receives from them;

· | NTIC’s relationships with its joint ventures and its ability to maintain those relationships, especially in light of anticipated succession planning issues;

· | NTIC’s dependence upon sales by Zerust Brazil to Petrobras and the effect of such sales on NTIC’s quarterly operating results, including in particular its net sales and margins;

· | The variability in NTIC’s sales of ZERUST® products and services into oil and gas industry and Natur-Tec® products and NTIC’s equity income of joint ventures, which variability in sales and equity in income of joint venture in turn, subject NTIC’s earnings to quarterly fluctuations;

· | Risks associated with NTIC’s international operations and exposure to fluctuations in foreign currency exchange rates and import duties and taxes;

· | Fluctuations in the cost and availability of raw materials, including resins and other commodities;

· | The success of and risks associated with NTIC’s emerging new businesses and products and services, including in particular NTIC’s ability and the ability of NTIC’s joint ventures to sell ZERUST® products and services into oil and gas industry and Natur-Tec® products and the often lengthy and extensive sales process involved in selling such products and services;

· | NTIC’s ability to introduce new products and services that respond to changing market conditions and customer demand;

· | Market acceptance of NTIC’s existing and new products, especially in light of existing and new competitive products;

· | Maturation of certain existing markets for NTIC’s ZERUST® products and services and NTIC’s ability to grow market share and succeed in penetrating other existing and new markets;

· | Increased competition, especially with respect to NTIC’s ZERUST® products and services, and the effect of such competition on NTIC’s and its joint ventures’ pricing, net sales and margins;

· | NTIC’s reliance upon and its relationships with its distributors, independent sales representatives and joint ventures;

· | NTIC’s reliance upon suppliers, including in particular its single supply source for its base bioplastics resins;

30

· | The costs and effects of complying with laws and regulations and changes in tax, fiscal, government and other regulatory policies, including rules relating to environmental, health and safety matters;

· | The transition of the manufacturing of certain select ZERUST® rust and corrosion inhibiting products in house at NTIC’s corporate headquarters location in Circle Pines, Minnesota;

· | Unforeseen product quality or other problems in the development, production and usage of new and existing products;

· | Unforeseen production expenses incurred in connection with new customers and new products;

· | Loss of or changes in executive management or key employees;

· | Ability of management to manage around unplanned events;

· | NTIC’s reliance on its intellectual property rights and the absence of infringement of the intellectual property rights of others;

· | Fluctuations in NTIC’s effective tax rate; and

· | NTIC’s reliance upon its management information systems.

For more information regarding these and other uncertainties and factors that could cause NTIC’s actual results to differ materially from what NTIC has anticipated in its forward-looking statements or otherwise could materially adversely affect its business, financial condition or operating results, see NTIC’s annual report on Form 10-K for the fiscal year ended August 31, 2012 under the heading “Part I. Item 1A. Risk Factors.”
All forward-looking statements included in this report are expressly qualified in their entirety by the foregoing cautionary statements. NTIC wishes to caution readers not to place undue reliance on any forward-looking statement that speaks only as of the date made and to recognize that forward-looking statements are predictions of future results, which may not occur as anticipated. Actual results could differ materially from those anticipated in the forward-looking statements and from historical results, due to the uncertainties and factors described above, as well as others that NTIC may consider immaterial or does not anticipate at this time. Although NTIC believes that the expectations reflected in its forward-looking statements are reasonable, NTIC does not know whether its expectations will prove correct. NTIC’s expectations reflected in its forward-looking statements can be affected by inaccurate assumptions NTIC might make or by known or unknown uncertainties and factors, including those described above. The risks and uncertainties described above are not exclusive and further information concerning NTIC and its business, including factors that potentially could materially affect its financial results or condition, may emerge from time to time. NTIC assumes no obligation to update, amend or clarify forward-looking statements to reflect actual results or changes in factors or assumptions affecting such forward-looking statements. NTIC advises you, however, to consult any further disclosures NTIC makes on related subjects in its annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K NTIC files with or furnishes to the Securities and Exchange Commission.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
NTIC maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to provide reasonable assurance that information required to be disclosed by NTIC in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to NTIC’s management, including NTIC’s principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. NTIC’s management evaluated, with the participation of its Chief Executive Officer and its Chief Financial Officer, the effectiveness of the design and operation of NTIC’s disclosure controls and procedures as of the end of the period covered in this report. Based on that evaluation, NTIC’s Chief Executive Officer and Chief Financial Officer concluded that NTIC’s disclosure controls and procedures were effective as of the end of such period to provide reasonable assurance that information required to be disclosed in the reports that NTIC files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to NTIC’s management, including NTIC’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There was no change in NTIC’s internal control over financial reporting that occurred during the quarter ended May 31, 2013 that has materially affected, or is reasonably likely to materially affect NTIC’s internal control over financial reporting, other than the consolidation of NTI Asean.
