PART I

ITEM 1.  BUSINESS

BUSINESS OVERVIEW

THE COMPANY

Biomerica, Inc. ("Biomerica", the "Company", "we" or "our") was incorporated in Delaware in September 1971 as Nuclear Medical Systems, Inc. The Company also has two wholly owned subsidiaries, Biomerica de Mexico, established for future use as a maquiladora and BioEurope GmbH, which acts as a distributor of Biomerica products in certain markets.

The Company develops, manufactures, and markets medical diagnostic products designed for the early detection and monitoring of chronic diseases and medical conditions. Our medical diagnostic products are sold worldwide in two markets: 1) clinical laboratories and 2) point of care (physicians' offices and over-the-counter drugstores). Our diagnostic test kits are used to analyze blood, urine, or fecal specimens from patients in the diagnosis of various diseases and other medical complications, or to measure the level of specific hormones, antibodies, antigens or other substances, which may exist in the human body in extremely small concentrations.

We primarily focus on products for gastrointestinal, food intolerances, diabetes and esoteric tests. These diagnostic test products utilize immunoassay technology. Some of these products have not yet been submitted for clearance by the Food and Drug Administration (“FDA”) or each country’s equivalent for diagnostic use, but can still be sold in various foreign countries without this approval.

Technological advances in medical diagnostics have made it possible to perform diagnostic tests within the home and the physician's office (the point of care), rather than in the clinical laboratory. One of our objectives has been to develop and market rapid diagnostic tests that are accurate, employ easily obtained specimens, and are simple to perform without instrumentation. Our over-the-counter and professional rapid diagnostic products help to manage existing medical conditions and may save lives through early detection and prompt diagnosis. In the past, tests of this kind required the services of medical technologists and sophisticated instrumentation. Frequently, results were not available until at least the following day. We believe that rapid point of care tests can be as accurate as laboratory tests when used properly, require no instrumentation, give reliable results in minutes and can be performed with confidence in the home or the physician's office.

Biomerica maintains its headquarters in Irvine, California where it houses administration, product development, sales and marketing, customer services and some manufacturing operations.  A part of Biomerica's manufacturing and assembly operations is located in Mexicali, Mexico, in order to reduce the cost of manufacturing and compete more effectively worldwide.  Biomerica has established wholly owned subsidiaries in Mexico and Germany for future use. The Company expended considerable funds in the effort to ready certain new products for market (both internally developed and licensed from others). We utilize technical personnel to conduct product improvement and technical transfer development activities, as well as explore potential new technologies that the Company may wish to develop. We are currently pursuing the development of a test for the gastrointestinal market.

PRODUCTION

Most of our diagnostic test kits are processed and assembled at our facilities in Irvine, California and in Mexicali, Mexico. We established our manufacturing facility in Mexicali, Mexico in fiscal 2003 and moved a significant portion of our diagnostic production (primarily a portion of our packaging and assembly) to that facility. We sublease facilities from and subcontract with Lancer Orthodontics (a former subsidiary) (“Lancer”) to provide labor and other services. Production of diagnostic tests can involve formulating component antibodies and antigens in specified concentrations, attaching a tracer to the antigen, filling components into vials, packaging and labeling. We continually engage in quality control procedures to assure the consistency and quality of our products and to comply with applicable FDA regulations. In June 2008, the Company incorporated in Mexico under the name of Biomerica de Mexico for the purpose of establishing our own maquiladora operation in Mexico at some time in the future.

3

Our manufacturing operations are regulated by the FDA Good Manufacturing Practices for medical devices. We have an internal Quality department that monitors and evaluates product quality and output. We also have an internal Quality Systems department which ensures that our operating procedures are in compliance with current FDA, CE Mark and International Organization for Standardization(“ISO”) regulations. We either produce our own antibodies and antigens or purchase these materials from qualified vendors. We have alternate, approved sources for most critical raw materials and are working to procure alternate sources for the few that we do not have. Based on our experience, we do not believe that material availability in the foreseeable future will be a problem.

RESEARCH AND DEVELOPMENT

While we have restructured our internal research group in favor of licensing in new technology from outside institutions to decrease time to market, we do utilize our technical personnel to develop new products especially where there is not outside technology licensing possible.  We are currently pursuing the development of two tests for the gastrointestinal market.  Our increase in research and development spending is due to our focus on these tests and the feasibility of possible FDA clearance for such a test. The Company also utilizes technical personnel to conduct other development activities, improve existing products, as well as explore potential new technologies that the Company may wish to develop. Research and development expenses include the costs of materials, supplies, personnel, facilities and equipment as well as outside contract services. Consolidated research and development expenses incurred by Biomerica for the years ended May 31, 2015 and 2014 aggregated $733,640 and $589,866, respectively.

MARKETS AND METHODS OF DISTRIBUTION

Biomerica has approximately 450 current customers for its diagnostic business, of which approximately 100 are foreign distributors, 21 are domestic distributors and the balance are hospital and clinical laboratories, medical research institutions, medical schools, pharmaceutical companies, chain drugstores, wholesalers and physicians' offices.

We rely on affiliated and unaffiliated distributors, advertising in medical and trade journals, exhibitions at trade shows, direct mailings and an internal sales staff to market our diagnostic products. We target two main markets: (a) clinical laboratories and (b) point of care testing (physicians' offices and over-the-counter drug stores). 

 

For the years ended May 31, 2015 and 2014, the Company had one distributor which accounted for 16.3% and 23.4%, respectively, of consolidated sales.  Sales by this distributor declined from fiscal 2014 to 2015 due to certain registrations that were necessary and which were completed in fiscal 2015.  The distributor has informed management that it anticipates improved sales results in fiscal 2016.

BACKLOG

At May 31, 2015 and 2014, Biomerica had a backlog of approximately and $154,000 and $376,000, respectively.

RAW MATERIALS

The principal raw materials utilized by Biomerica consist of various chemicals, serums, reagents and packaging supplies. Almost all of our raw materials are available from several sources, and we are not dependent upon any single source of supply or a few suppliers.   However, due to the limited number of suppliers of some materials, especially those such as antibodies, there is always the possibility that the Company may encounter difficulty in the future obtaining key raw materials for its manufacturing processes or that such materials may be exceedingly costly. For the year ended May 31, 2015, one company accounted for 13.6% of the purchases of raw materials. For the year ended May 31, 2014, two companies combined accounted for 30.2% of the purchases for raw materials.

Our inventory consists of various types of materials including antibodies, antigens, bottles, boxes, various chemicals and reagents utilized in the manufacture of our test kits as well as products in various stages of completion.

COMPETITION

Immunodiagnostic products are currently produced by more than 100 companies. Biomerica is not a significant player in the overall market.

Our competitors vary greatly in size. Many are divisions or subsidiaries of well-established medical and pharmaceutical companies which are much larger than Biomerica and expend substantially greater amounts than we do for research and development, manufacturing, advertising and marketing.

The primary competitive factors affecting the sale of diagnostic products are uniqueness, technology, quality of product, performance, price, service and marketing. We believe we compete primarily on the basis of the uniqueness of our products, the quality of our products, the speed of our test results, our patent position, our favorable pricing and our prompt shipment of orders. We offer a broader range of products than many competitors of comparable size, but have had limited marketing capability. We are working on expanding this capability through marketing and strategic cooperation with larger companies and distributors.

GOVERNMENT REGULATION OF OUR DIAGNOSTIC BUSINESS

Our primary business consists of selling products that are legally defined to be medical devices. As a result, we are considered to be a medical device manufacturer, and as such are subject to the regulations of numerous governmental entities. These agencies include the FDA, Environmental Protection Agency, Federal Trade Commission, Occupational Safety and Health Administration, U.S. Department of Agriculture ("USDA"), and Consumer Product Safety Commission. These activities are also regulated by various agencies of the states and localities in which our products are sold. These regulations govern the introduction of new medical devices, the observance of certain standards with respect to the manufacture and labeling of medical devices, the maintenance of certain records, the reporting of potential product problems, and other matters.

The Food, Drug & Cosmetic Act of 1938 (the "FDCA") regulates medical devices in the United States by classifying them into one of three classes based on the extent of regulation believed necessary to ensure safety and effectiveness. Class I devices are those devices for which safety and effectiveness can reasonably be assured through general controls, such as device listing, adequate labeling, and adherence to the Quality System Regulation ("QSR") as well as Medical Device Reporting (“MDR”), labeling and other regulatory requirements. Some Class I medical devices are exempt from the requirement of Pre-Market Notification or clearance. Class II devices are those devices for which safety and effectiveness can reasonably be ensured through the use of special controls, such as performance standards, post-market surveillance and patient registries, as well as adherence to the general controls provisions applicable to Class I devices. Class III devices are devices that generally must receive clearance prior to marketing by the FDA pursuant to a pre-market notification to ensure their safety and effectiveness. Generally, Class III devices are limited to life-sustaining, life-supporting or implantable devices. However, this classification can also apply to novel technology or new intended uses or applications for existing devices. The Company's products are primarily either Class I or Class II medical devices.

Pursuant to FDA requirements, we have registered our manufacturing facility with the FDA as a medical device manufacturer, and listed the medical devices we manufacture. We are also subject to inspection on a routine basis for compliance with FDA regulations. This includes the QSR, which requires that we manufacture our products and maintain our documents in a prescribed manner with respect to issues such as design controls, manufacturing, testing and validation activities. Further, we are required to comply with other FDA requirements with respect to labeling, and MDR regulation which requires that we provide information to the FDA on deaths or serious injuries alleged to have been associated with the use of our products, as well as product malfunctions that are likely to cause or contribute to death or serious injury if the malfunction were to recur. We believe that we are currently in material compliance with all relevant QSR and MDR requirements.

5

In addition, our facility is required to have a California Medical Device Manufacturing License. The license is not transferable and must be renewed biannually. Approval of the license requires that we be in compliance with QSR, labeling and MDR regulations. Our license expires on November 19, 2016. These licenses are renewed periodically, and to date we have never failed to obtain a renewal.

Through compliance with FDA and California regulations, we can market our medical devices throughout the United States. International sales of medical devices are also subject to the regulatory requirements of each country. In Europe, the regulations of the European Union (“EU’) require that a device have a "CE Mark" in order to be sold in EU countries. The directive went into effect beginning December 7, 2003. The Company has completed the process for complying with the "CE Mark" directives; and In Vitro Diagnostics Directive 98/79/EC. We also comply with ISO 13485 for medical devices.

At present, outside the EU the regulatory international review process varies from country to country. We, in general, rely upon our distributors and sales representatives in the foreign countries in which we market our products to ensure that we comply with the regulatory laws of such countries. We believe that our international sales to date have been in compliance with the laws of all the foreign countries in which we have made sales. Exports of most medical devices are also subject to certain FDA regulatory controls.

Biomerica is licensed to design, develop, manufacture and distribute in vitro diagnostic and medical devices and is subject to the Code of Federal Regulations, Section 21, parts 800 - 1299. The FDA is the governing body that assesses and issues Biomerica's license to assure that it complies with these regulations. Biomerica is currently licensed, and its last assessment was in February 2015. During the inspection, the FDA noted five observations that were corrected in a timely manner. Biomerica is also registered and licensed with the State of California's Department of Health Services. The last audit with the State of California was in November 2009 and no observations were noted.  The Company believes that all Biomerica products sold in the U.S. comply with the FDA and state regulations.

Biomerica's Quality Management System is in compliance with the EN ISO 13485:2003. EN ISO 13485:2003 is an internationally recognized standard in which companies establish their methods of operation and commitment to quality.

SEASONALITY OF BUSINESS

The businesses of the Company and its subsidiaries have not been subject to significant seasonal fluctuations.

We recognize that our foreign sales could be subject to some special or unusual risks, which are not present in the ordinary course of business in the United States. Changes in economic factors, government regulations, terrorism and import restrictions all could impact sales within certain foreign countries. Foreign countries have licensing requirements applicable to the sale of diagnostic products, which vary substantially from domestic requirements; depending upon the product and the foreign country, these may be more or less restrictive than requirements within the United States. Foreign diagnostic sales at Biomerica are made primarily through a network of approximately 100 independent distributors in approximately 65 countries.

INTELLECTUAL PROPERTY

We regard the protection of our copyrights, service marks, trademarks and trade secrets as important to our future success. We rely on a combination of copyright, trademark, patents, service mark and trade secret laws and contractual restrictions to establish and protect our proprietary rights in products and services. We have entered into confidentiality and invention assignment agreements with our employees and contractors, and nondisclosure agreements with most of our fulfillment partners and strategic partners to limit access to and disclosure of proprietary information. We cannot be certain that these contractual arrangements or the other steps taken by us to protect our intellectual property will prevent misappropriation of our technology. We have licensed in the past, and expect that we may license in the future, certain of our proprietary rights, such as trademarks or copyrighted material, to third parties. While we attempt to ensure that the quality of our product brands is maintained by such licensees, we cannot be certain that such licensees will not take actions that might hurt the value of our proprietary rights or reputation.

BRANDS, TRADEMARKS, PATENTS, LICENSES

We registered the tradenames "Fortel", "Isletest", and "GAP" with the Office of Patents and Trademarks on December 31, 1985. Our unregistered tradenames are "EZ-Detect", "EZ-H.P" and "EZ-PSA". A trademark for "Aware" was issued and assigned in November 2001 and renewed in 2011. In addition, Biomerica holds the following patent: Diagnostic Test for Measuring Islet Cell Autoantibodies and Reagents Relating Thereto, U.S. Patent #5,786,221, issued July 28, 1998. Biomerica has obtained the rights to manufacture and sell certain products. In some cases royalties are paid on the sales of these products. Biomerica anticipates that it will license or purchase the rights to other products or technology in the future.  Biomerica has filed several patent applications with regard to new tests to identify possible triggers for causing specific symptoms.

The laws of some foreign countries do not protect our proprietary rights to the same extent as do the laws of the U.S. Effective copyright, trademark and trade secret protection may not be available in such jurisdictions. Our efforts to protect our intellectual property rights may not prevent misappropriation of our content. In addition, there can be no assurance that Biomerica is not violating any third party patents.

On March 27, 2009, the Company signed an Asset Purchase Agreement with a European company for the purchase of certain technology related to the manufacture of certain medical diagnostic tests.  Consideration for this purchase was a nominal deposit upon signing the agreement and a nominal transfer fee upon successful commencement of production of the products.  A royalty shall be paid for five years beginning on the date of first sale of finished product derived from the purchased assets.   Royalty expense for this license was approximately $1,400 and $600 for the years ended May 31, 2015 and 2014, respectively.

In October 2009, the Company entered into a non-exclusive, worldwide, perpetual, irrevocable, and transferable cross-license agreement to acquire technology and intellectual property from and make available its technology and intellectual property related to enzyme-linked immunosorbent assay products to be marketed by the Company. Pursuant to the terms of the license agreement, the Company has paid $25,000 for the license for each of six products, with a similar amount to be paid for one additional product if it is transferred. The Company will be amortizing the costs for these licenses over a ten year period. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% and is eligible to receive royalties from certain of its products licensed in the same percentages. The Company accrues this royalty when it becomes payable.  The Company incurred approximately $15,000 per year in amortization of licensing fees during fiscal 2015 and 2014.

7

In May 2010, the Company acquired from an inventor the exclusive, perpetual license to a United States patent applicable to the measurement of thiopurine methyltransferase within patients prior to commencing treatment with thiopurine drugs. The product is currently being redeveloped by the Company. Pursuant to the terms of the license agreement, the Company was granted an exclusive, worldwide, perpetual license to manufacture, market, distribute and sell the products contemplated by the patents subject to the payment of $25,000 as reimbursement to the patent holder for legal and other costs associated with obtaining the patent, which was paid in June 2010. The Company is amortizing the initial cost of $25,000 for this license over a ten year period.  As of May 31, 2015 the Company has amortized $12,500 of this. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% through September 30, 2022. The agreement also has minimum escalating royalty payments which must be made for the Company to keep its exclusivity for the license. The Company accrues this royalty when it becomes payable.   Royalty in the amount of approximately $1,200 was recorded in fiscal 2015. A credit to royalty expense in the amount of $8,300 was recorded in fiscal 2014 due to over accrual of such royalty.

On October 19, 2010, the Company signed an agreement with a university to acquire the rights to manufacture and market certain products using two patents owned by the university.  The Company paid a license issue fee of $15,000 initially and will pay royalties on net sales quarterly.  The Company has amortized all of this licensing fee as of May 31, 2015.  Royalty expense for this license was approximately $4,500 and $6,900 for the years ended May 31, 2015 and 2014, respectively.

The Company has two royalty agreements in which it has obtained rights to manufacture and market certain products for the life of the products. Royalty expense of approximately $21,000 is included in cost of sales for these agreements for each of the years ended May 31, 2015 and 2014. Beginning in fiscal 2011, the supplier was only required to pay royalties for one of the products due to the fact that the company no longer provides materials to make the other product, which was part of the original agreement. Sales of products manufactured under these agreements comprise approximately 3.2% and 3.0% of total sales for the years ended May 31, 2015 and 2014, respectively. The Company may license other products or technology in the future as it deems necessary for conducting this line of business.

EMPLOYEES

As of May 31, 2015 and 2014, the Company employed 36 employees, respectively, one of whom is employed part-time in the United States. The following is a breakdown between departments:

	2015	2014
Administrative	5	5
Marketing & Sales	3	3
Production and Operations	28	28
Total	36	36

In addition, Biomerica contracts with Lancer for the services of 18 people at its Mexico facility. We also engage the services of various outside Ph.D. and M.D. consultants as well as medical institutions for technical support on a regular basis. We are not a party to any collective bargaining agreement and have never experienced a work stoppage. We consider our employee relations to be good.

ITEM 1A.  RISK FACTORS

Although not required to disclose risk factors, Biomerica has chosen to inform users of its financial information about certain risks associated with the Company’s operations below.

Distribution - Biomerica has entered into various exclusive and non-exclusive distribution agreements (the "Agreements") which generally specify territories of distribution. The Agreements range in term from one to five years. Biomerica may be dependent upon such distributors for the marketing and selling of its products worldwide during the terms of these agreements. Such distributors are generally obligated to sell specified minimum quantities of the Company's products to keep the exclusive, while non-exclusive distributors have no minimum purchase requirements. There can be no assurance of the volume of product sales that may be achieved by such distributors. The Company has several large distributors which account for a significant portion of its business. The Company terminated the agreement with one such distributor in fiscal 2013 due to certain proprietary disagreements however the Company replaced this last distributor with a new distributor. The loss of one of these distributors could adversely affect the Company's financial results.

8

Government Regulation - Biomerica's immunodiagnostic products are regulated in the United States as medical devices primarily by the FDA and as such, require regulatory clearance or approval prior to commercialization in the United States. Pursuant to the Food, Drug and Cosmetics Act, and the regulations promulgated thereunder, the FDA regulates, among other things, the clinical testing, manufacture, labeling, promotion, distribution, sale and use of medical devices in the United States. Failure of Biomerica to comply with applicable regulatory requirements can result in, among other things, warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, the government's refusal to grant pre-market clearance or pre-market approval of devices, withdrawal of marketing approvals, and criminal prosecution. In addition, there is the possibility that new health care reform laws may have a negative impact on the Company’s sales.

Sales of medical devices outside the United States are subject to foreign regulatory requirements that vary widely from country to country. The time required to obtain registrations or approvals required by foreign countries may be longer or shorter than that required for FDA clearance or approval, and requirements for licensing may differ significantly from FDA requirements. There can be no assurance that Biomerica will be able to obtain regulatory clearances for its current or any future products in the United States or in foreign markets.

European Community - Biomerica is required to obtain certification in the European community to sell products in those countries. The certification requires Biomerica to maintain certain quality standards. Biomerica has been granted certification and undergoes annual audits to assure that the Company remains in compliance with regulations. There is no assurance that Biomerica will be able to retain its certification in the future. The loss of business or the ability to conduct business in Europe could materially adversely affect the results of the Company.

Risk of Product Liability - Testing, manufacturing and marketing of Biomerica's products entails risk of product liability. In addition, the Company may have unknown intellectual property risks associated with patent or trademark infringement of other companies as well as having other companies infringe on our intellectual property . Biomerica currently has product liability insurance. There can be no assurance, however, that Biomerica will be able to maintain such insurance at a reasonable cost or in sufficient amounts to protect Biomerica against losses due to product liability. An inability to obtain sufficient insurance coverage could prevent or inhibit the commercialization of Biomerica's products. In addition, a product liability claim or recall could have a material adverse effect on the business or financial condition of the Company.

Hazardous Materials - Biomerica's manufacturing and research and development involves the controlled use of hazardous materials and chemicals. Although Biomerica believes that safety procedures for handling and disposing of such materials comply with the standards prescribed by state and Federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, the Company could be held liable for any damages that result and any such liability could exceed the resources of the Company. The Company may incur substantial costs to comply with environmental regulations.

Common stock performance - The common stock of the Company is subject to fluctuations as a result of a variety of factors including, but not limited to, financial results, general economic conditions, fluctuations in sales volumes and expenses, competition, and our failure to generate new products.  The loss of one or more employees in senior management could adversely impact the Company’s stock value.

Raw Materials - The Company utilizes certain raw materials that are critical to its manufacturing processes and relies on a limited number of manufacturers of such materials.  Should any of these materials become unavailable or extremely cost prohibitive the sales of the Company could be adversely affected.

9

Ability to Obtain Financing - Although the Company has been able to obtain financing in the past, there is no guarantee that the Company will be able to obtain financing that may be needed in the future.

Limited Trading - The Company is traded on the Over-the-Counter stock market.  Trading on this exchange is limited and liquidation of the Company’s stock may be difficult as there is a limited market for the Company’s stock.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 2.  PROPERTIES

The Company leases its office facilities. At May 31, 2015, the Company had approximately 22,000 square feet of floor space at its corporate headquarters at 17571 Von Karman Avenue in Irvine, California, 92614 which it has been leasing since 2009. The lease for its headquarters expires on August 31, 2016.  The Company has an option to extend the term of its lease for two additional sixty month periods. The Company also leases approximately 7,000 square feet of floor space in Mexico on a month-to-month basis as well as a smaller unit for use in one manufacturing process. In addition, the Company leases a small office in Lindau, Germany, as headquarters for BioEurope GmbH, its Germany subsidiary.

Overview

Biomerica, Inc. and Subsidiaries (which includes wholly owned subsidiaries, Biomerica de Mexico and BioEurope GmbH) develop, manufacture, and market medical diagnostic products designed for the early detection and monitoring of chronic diseases and medical conditions. Our medical diagnostic products are sold worldwide in two markets: 1) clinical laboratories and 2) point of care (physicians' offices and over-the-counter drugstores). Our diagnostic test kits are used to analyze blood, urine or fecal material from patients in the diagnosis of various diseases, food intolerances and other medical complications, or to measure the level of specific hormones, antibodies, antigens or other substances, which may exist in the human body in extremely small concentrations.

RESULTS OF OPERATIONS

Our consolidated net sales were $4,962,373 for fiscal 2015 compared to $5,120,451 for fiscal 2014. This represents a decrease of $158,078, or 3.1%. The sales decrease was a result of decreased sales in Asia, a result of lengthy registration processes that were resolved in fiscal 2015 in addition to a decrease in sales in the U.S. due to lower OTC sales for our EZ Detect product screening programs.

Consolidated cost of sales in fiscal 2015 as compared to fiscal 2014 decreased from $3,451,243 to $3,420,567 or by $30,676. The percentage of cost of sales relative to sales increased from 67.4%, to 68.9%, or by 1.5%, due to various factors which included decreased sales which resulted in higher cost of labor and overhead per unit due to fixed costs.

Consolidated selling, general and administrative costs decreased in fiscal 2015 as compared to fiscal 2014 from $1,525,936 to $1,478,761, or by $47,175. The decrease was primarily a result of lower commissions, outside services and bad debt expense.

Consolidated research and development expense was $733,640 in fiscal 2015 as compared to $589,866 in fiscal 2014. This is an increase of $143,774, primarily as a result of increased costs related to the possible FDA clearance of a new gastrointestinal product and feasibility for FDA clearance.

Interest expense decreased to $0 in fiscal 2015 as compared to $142 in fiscal 2014. Interest and dividend income increased from $17,183 to $21,906 due to higher dividends from the Company’s investment in its Polish distributor.

Other income decreased from $3,133 to $2,255, a decrease of $878.

LIQUIDITY AND CAPITAL RESOURCES

As of May 31, 2015, the Company had cash and cash equivalents in the amount of $1,088,307 as compared to $1,509,125 of cash and cash equivalents as of May 31, 2014.  As of May 31, 2015 and 2014, the Company had working capital of $3,941,668 and $4,357,330, respectively.

Operating Activities

During fiscal 2015, cash used in operating activities was $405,481 as compared to $862,273 in fiscal 2014. The decrease in cash used of $456,792 in fiscal 2015 was primarily due to the collection of $348,667 of accounts receivable, and an increase in accrued compensation of $17,631 as compared to an increase in accounts receivable totaling $490,316 in fiscal 2014 and a decrease in accrued compensation of $93,813.

12

Investing Activities

During fiscal 2015, cash used in investing activities was $22,782 as compared to $282,530 in fiscal 2014. Cash of $10,503 and $137,234 was utilized for the purchase of property and equipment in fiscal 2015 and 2014, respectively. In fiscal 2015, the Company invested $14,179 into licenses for new products and product registration fees as compared to $146,496 in fiscal 2014.

Financing Activities

Cash provided by financing activities in fiscal 2015 was $9,560 as compared to $185,275 in fiscal 2014. In fiscal 2014 the Company realized $150,000 from the proceeds from the sale of common stock.

During the fiscal year ended May 31, 2014, the Company sold 200,000 shares of its common stock at a price of $1.25 per share to an investor, the new distributor in China, for proceeds of $250,000, $150,000 of which was received in cash and $100,000 of which was invested in intangible costs related to product registrations.  

Other

In March 2014, the Company entered into a line of credit (the "Line") with its bank which had a borrowing limit of $250,000. The line was secured by substantially all of the Company’s assets, bore an interest rate of 2.0% plus the Wall Street Journal Prime West Coast Edition prime rate. This line of credit expired in March 2015 and has not been renewed.  The Company is investigating other sources of operating capital to support its research activities.

OFF BALANCE SHEETS ITEMS

There were no off-balance sheet arrangements as of May 31, 2015.

CRITICAL ACCOUNTING POLICIES

The discussion and analysis of our financial condition and results of operations are based on the consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Note 2 of the Consolidated Financial Statements describe the significant accounting policies essential to the consolidated financial statements. The preparation of these consolidated financial statements requires estimates and assumptions that affect the reported amounts and disclosures.

In general, the critical accounting policies that may require judgments or estimates relate specifically to Revenues, Allowance for Doubtful Accounts, Inventory Reserves, Stock-Based Compensation, and Income Taxes.

We believe the following to be critical accounting policies as they require more significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenues from product sales are recognized at the time the product is shipped, customarily FOB shipping point, at which point title passes. An allowance is established if necessary for estimated returns as revenue is recognized.

An allowance for doubtful accounts is established for estimated losses resulting from the inability of our customers to make required payments. The assessment of specific receivable balances and required reserves is performed by management and discussed with the audit committee. We have identified specific customers where collection is not probable and have established specific reserves, but to the extent collection is made, the allowance will be released. Additionally, if the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Reserves are provided for excess and obsolete inventory, which are estimated based on a comparison of the quantity and cost of inventory on hand to management's forecast of customer demand. Customer demand is dependent on many factors and requires us to use significant judgment in our forecasting process. We must also make assumptions regarding the rate at which new products will be accepted in the marketplace and at which customers will transition from older products to newer products. Once a reserve is established, it is maintained until the product to which it relates is sold or otherwise disposed of, even if in subsequent periods we forecast demand for the product.

13

We measure stock-based compensation costs at fair value, including estimated forfeitures, and recognize the expense over the period that the recipient is required to provide service in exchange for the award, which generally is the vesting period. We use the Black-Scholes option pricing model to measure the fair value of our stock options. In determining the amount of expense to be recorded, we also estimate forfeiture rates for all awards based on historical experience to reflect the probability that employees will complete the required service period. Employee retention patterns could vary in the future and result in a change to our estimated forfeiture rate which would directly impact stock-based compensation expense.

We follow authoritative guidance to evaluate whether a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using a “more likely than not” standard.  In making such judgments, significant weight is given to evidence that can be objectively verified. We assess our deferred tax assets annually under more likely than not scenarios in which they may be realized through future income. We have determined that it was more likely than not that our deferred tax assets will be realized in the future. 

FACTORS THAT MAY AFFECT FUTURE RESULTS

You should read the following factors in conjunction with the factors discussed elsewhere in this and our other filings with the Securities and Exchange Commission and in materials incorporated by reference in these filings. The following is intended to highlight certain factors that may affect the financial condition and results of operations of Biomerica, Inc. and Subsidiaries and are not meant to be an exhaustive discussion of risks that apply to companies such as Biomerica, Inc. and Subsidiaries. Like other businesses, Biomerica, Inc. and Subsidiaries are susceptible to macroeconomic downturns in the United States or abroad, as were experienced recently, that may affect the general economic climate and performance of Biomerica, Inc. and Subsidiaries or its customers.

Aside from general macroeconomic downturns, the additional material factors that could affect future financial results include, but are not limited to: Terrorist attacks and the impact of such events; diminished or no access to raw materials that directly enter into our manufacturing process; shipping labor disruption or other major degradation of the ability to ship out products to end users; inability to successfully control our margins which are affected by many factors including competition and product mix; protracted shutdown of the U.S. border due to an escalation of terrorist or counter terrorist activity; any changes in our business relationships with international distributors or the economic climate they operate in; any event that has a material adverse impact on our foreign manufacturing operations may adversely affect our operations as a whole; failure to manage the future expansion of our business could have a material adverse effect on our revenues and profitability; possible costs in complying with government regulations and the delays in receiving required regulatory approvals or the enactment of new adverse regulations or regulatory requirements; numerous competitors, some of which have substantially greater financial and other resources than we do; potential claims and litigation brought by patients or medical professionals alleging harm caused by the use of or exposure to our products; recalls of products; quarterly variations in operating results caused by a number of factors, including business and industry conditions; and other factors beyond our control. All these factors make it difficult to predict operating results for any particular period.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.  CONTROLS AND PROCEDURES

Attached as exhibits to this Form 10-K are certifications of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) that are required in accordance with Rule 13a-14 of the Exchange Act. This “Disclosure Controls and Procedures” section includes information concerning the controls and controls evaluation referred to in the certifications.

EVALUATION OF DISCLOSURE CONTROLS

Our management evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act as of the end of the period covered by this report.  Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.  The disclosure controls and procedures have been designed to provide reasonable assurance of achieving their objectives and the CEO and CFO have concluded that our disclosure controls and procedures are effective at the “reasonable assurance” level. Based on that evaluation the CEO and CFO concluded that information required to be disclosed in the reports that we file and submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms; and (2) accumulated and communicated to the Company’s management, including its CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

For the reasons discussed in "Management's Report on Internal Control over Financial Reporting" below, Company management, including the CEO and CFO concluded that, as of May 31, 2015, the Company's internal control over financial reporting was effective. Management has concluded that the consolidated financial statements included in this annual report present fairly, in all material respects, the Company's financial position, results of operations, and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There have been no changes in our internal control over financial reporting identified in connection with the evaluation that occurred during the last fiscal quarter that has materially affected, or that is reasonably likely to affect, our internal control over financial reporting.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Company management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance to the Company's management and Board of Directors regarding the reliability of financial reporting and the preparation and fair presentation of financial statements for external purposes in accordance with generally accepted accounting principles.

A Company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the consolidated financial statements.

15

The effectiveness of any system of internal control over financial reporting is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating and evaluating the controls and procedures. Because of these inherent limitations, internal control over financial reporting cannot provide absolute assurance regarding the reliability of financial reporting and may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Company management, with the participation of the CEO and the CFO, evaluated the effectiveness of the Company's disclosure controls and procedures as defined in Rules 13(a)-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as of the end of the period covered by this report. In making this assessment, Management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013). Based on this assessment, management, with the participation of the CEO and CFO, believes that, as of May 31, 2015, the Company's internal control over financial reporting was effective based on those criteria.

Company management will continue to monitor and evaluate the effectiveness of its disclosure controls and procedures and its internal controls over financial reporting on an ongoing basis and are committed to taking further action and implementing improvements, as necessary and as funds allow.

Note: This 10-K does not include an attestation report of the Company's registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by the Company's registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management's report in this 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Biomerica, Inc. and Subsidiaries

Irvine, California

We have audited the accompanying consolidated balance sheets of Biomerica, Inc. (a Delaware Corporation) and Subsidiaries (the "Company") as of May 31, 2015 and 2014 and the related consolidated statements of operations and comprehensive loss, shareholders' equity, and cash flows for each of the two years then ended. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We have conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal controls over financial reporting. Our audits included consideration of internal controls over financial reporting as a basis for designing audit procedures that are appropriate in the circumstance, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Biomerica, Inc. and Subsidiaries as of May 31, 2015 and 2014, and the results of its consolidated operations and cash flows for each of the two years then ended in conformity with accounting principles generally accepted in the United States of America.

BIOMERICA, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

YEARS ENDED MAY 31, 2015 AND 2014

1.    ORGANIZATION

Biomerica, Inc. and Subsidiaries (collectively "the Company") are primarily engaged in the development, manufacture and marketing of medical diagnostic kits. 

The Company develops, manufactures, and markets medical diagnostic products designed for the early detection and monitoring of chronic diseases and medical conditions. The Company’s medical diagnostic products are sold worldwide in two markets: 1) clinical laboratories and 2) point of care (physicians' offices and over-the-counter drugstores). The diagnostic test kits are used to analyze blood, urine or fecal samples from patients in the diagnosis of various diseases and other medical complications, or to measure the level of specific hormones, antibodies, antigens or other substances, which may exist in the human body in extremely small concentrations.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements for the years ended May 31, 2015 and 2014 include the accounts of Biomerica, Inc. ("Biomerica") as well as its German subsidiary and Mexican subsidiary. The Mexican subsidiary has not begun operations. All significant intercompany accounts and transactions have been eliminated in consolidation.

ACCOUNTING ESTIMATES

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reported period. Actual results could materially differ from those estimates.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company has financial instruments whereby the fair market value of the financial instruments could be different than that recorded on a historical basis. The Company's financial instruments consist of its cash and cash equivalents, accounts receivable, and accounts payable. The carrying amounts of the Company's financial instruments approximate their fair values.

CONCENTRATION OF CREDIT RISK

The Company maintains cash balances at certain financial institutions in excess of amounts insured by federal agencies.  The Company does not believe it is exposed to any significant credit risks.

The Company provides credit in the normal course of business to customers throughout the United States and foreign markets. For the years ended May 31, 2015 and 2014, the Company had one distributor which accounted for 16.3% and 23.4%, respectively, of consolidated sales. The Company performs ongoing credit evaluations of its customers and requires prepayment in some circumstances. At May 31, 2015, two customers accounted for 53.0% of gross accounts receivable. At May 31, 2014, two customers accounted for 60.5% of gross accounts receivable.

FS-7

For the year ended May 31, 2015, one company accounted for 13.6% of the purchases of raw materials. For the year ended May 31, 2014, two companies accounted for 30.2% of the purchases of raw materials.

GEOGRAPHIC CONCENTRATION

As of May 31, 2015 and 2014, approximately $530,000 and $443,000 of Biomerica's gross inventory and approximately $35,000 and $43,000, of Biomerica's property and equipment, net of accumulated depreciation and amortization, was located in Mexicali, Mexico, respectively.

CASH EQUIVALENTS

Cash and cash equivalents consist of demand deposits and money market accounts with original maturities of less than three months.

ACCOUNTS RECEIVABLE

The Company extends unsecured credit to its customers on a regular basis.  International accounts are required to prepay until they establish a history with the Company and at that time, they are extended credit at levels based on a number of criteria.  Credit levels are approved by designated upper level management.  Domestic customers are extended initial $500 credit limits until they establish a history with the Company or submit credit information.  All increases in credit limits are also approved by designated upper level management.  Management evaluates receivables on a quarterly basis and adjusts the allowance for doubtful accounts accordingly.  Balances over ninety days old are usually reserved for.  

Occasionally certain long-standing customers, who routinely place large orders, will have unusually large receivables balances relative to the total gross receivables.   Management monitors the payments for these large balances closely and very often requires payment of existing invoices before shipping new sales orders.

INVENTORIES

The Company values inventory at the lower of cost (determined using a combination of specific lot identification and the first-in, first-out methods) or market. Management periodically reviews inventory for excess quantities and obsolescence. Management evaluates quantities on hand, physical condition, and technical functionality as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. The reserve is adjusted based on such evaluation, with a corresponding provision included in cost of sales. Abnormal amounts of idle facility expenses, freight, handling costs and wasted material are recognized as current period charges and the allocation of fixed production overhead is based on the normal capacity of the production facilities.

Inventories approximate the following at May 31:

	2015		2014
Raw materials	$	958,000	$	899,000
Work in progress		831,000		635,000
Finished products		238,000		232,000
Total	$	2,027,000	$	1,766,000

Reserves for inventory obsolescence are recorded as necessary to reduce obsolete inventory to estimated net realizable value or to specifically reserve for obsolete inventory that the Company intends to dispose of.  For the years ended May 31, 2015 and 2014 inventory reserves were approximately $25,000 and $43,000, respectively.

FS-8

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Expenditures for additions and major improvements are capitalized. Repairs and maintenance costs are charged to operations as incurred. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation or amortization are removed from the accounts, and gains or losses from retirements and dispositions are credited or charged to income.

Depreciation and amortization are provided over the estimated useful lives of the related assets, ranging from 5 to 10 years, using the straight-line method. Leasehold improvements are amortized over the lesser of the estimated useful life of the asset or the term of the lease. Depreciation and amortization expense on property and equipment and leasehold improvements amounted to $178,219 and $177,518 for the years ended May 31, 2015 and 2014, respectively.

INTANGIBLE ASSETS

Intangible assets include trademarks, product rights, technology rights and patents, and are accounted for based on Accounting Standards Codification (“ASC”), ASC 350 “Intangibles – Goodwill and Other” (ASC 350). In that regard, intangible assets that have indefinite useful lives are not amortized but are tested at least annually for impairment or more frequently if events or changes in circumstances indicate that the asset might be impaired.

Intangible assets are being amortized using the straight-line method over the useful life, not to exceed 18 years for marketing and distribution rights and purchased technology use rights, and 17 years for patents. Amortization amounted to $75,056 and $29,515 for the years ended May 31, 2015 and 2014, respectively. Intangible assets with indefinite lives such as perpetual licenses are not amortized but rather tested for impairment at least annually.

The Company assesses the recoverability of these intangible assets by determining whether the amortization of the asset's balance over its remaining life can be recovered through projected undiscounted future cash flows. In July 2012,the FASB issued another update to ASC 350 Intangibles – Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment. This update simplifies the guidance for testing impairment of indefinite-lived intangible assets other than goodwill. During fiscal 2013, the Company adopted the updated guidance in ASC 350 and used the qualitative assessment to determine whether there was any impairment. No impairment adjustment was required as of May 31, 2015.

INVESTMENTS

From time-to-time, the Company makes investments in privately-held companies.  The Company determines whether the fair values of any investments in privately-held entities have declined below their carrying value whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable.  If the Company considers any such decline to be other than temporary (based on various factors, including historical financial results, and the overall health of the investee’s industry), a write-down to estimated fair value is recorded. The Company currently has not written down the investment and no events have occurred which could indicate the carrying value to be less than the fair value. Investments represent the Company’s investment in a Polish distributor which is primarily engaged in distributing medical devices.  The Company owns approximately 6% of the investee, and accordingly, applies the cost method to account for the investment.  Under the cost method, investments are recorded at cost, with gains and losses recognized as of the sale date, and income recorded when received.

FS-9

SHARE-BASED COMPENSATION

The Company follows the guidance of the accounting provisions of ASC 718 “Share-based Compensation” (ASC 718), which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (warrants and options). The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected forfeiture rate, expected term, and the risk-free interest rate. Expected volatilities are based on weighted averages of the historical volatility of the Company’s stock estimated over the expected term of the options. The expected forfeiture rate is based on historical forfeitures experienced. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term as historically the Company had limited activity surrounding its options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term.

In applying the Black-Scholes options-pricing model, assumptions are as follows:  

	2015	2014
Dividend yield	0%	0%
Expected volatility	49.53-62.68%	48.65-49.85%
Risk free interest rate	1.26-1.67%	0.84-1.155%
Expected life	3.75-6.0 years	3.50 years

REVENUE RECOGNITION

Revenues from product sales are recognized at the time the product is shipped, customarily FOB shipping point, at which point title passes. An allowance is established when necessary for estimated returns as revenue is recognized. As of May 31, 2015 and 2014, the allowance for returns is $0.

SHIPPING AND HANDLING FEES AND COSTS

Shipping and handling fees billed to customers are required to be classified as net sales, and shipping and handling costs are required to be classified as either cost of sales or disclosed in the notes to the financial statements. The Company included shipping and handling fees billed to customers in net sales. The Company included shipping and handling costs associated with inbound freight and unreimbursed shipping to customers in cost of sales.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred. The Company expensed $733,640 and $589,866 of research and development expenses during the years ended May 31, 2015 and 2014, respectively.

INCOME TAXES

The Company accounts for income taxes in accordance with ASC 740, “Income Taxes” (ASC 740). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. These temporary differences are measured using enacted tax rates. A valuation allowance is recorded to reduce deferred tax assets to the extent that management considers it is more likely than not that a deferred tax asset will not be realized. In determining the valuation allowance, the Company considers factors such as the reversal of deferred income tax liabilities, projected taxable income, and the character of income tax assets and tax planning strategies. A change to these factors could impact the estimated valuation allowance and income tax expense.

The Company accounts for its uncertain tax provisions by using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained in an audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the appropriate amount of the benefit to recognize. The amount of benefit to recognize is measured as the maximum amount which is more likely than not to be realized. The tax position is derecognized when it is no longer more likely than not capable of being sustained. On subsequent recognition and measurement the maximum amount which is more likely than not to be recognized at each reporting date will represent the Company’s best estimate, given the information available at the reporting date, although the outcome of the tax position is not absolute or final. Upon adopting the revisions in ASC 740, the Company elected to follow an accounting policy to classify accrued interest related to liabilities for income taxes within the “Interest expense” line and penalties related to liabilities for income taxes within the “Other expense” line of the consolidated statements of operations and comprehensive loss.

FS-10

ADVERTISING COSTS

The Company reports the cost of all advertising as expense in the period in which those costs are incurred. Advertising costs were approximately $6,000 and $8,000 for the years ended May 31, 2015 and 2014, respectively.

FOREIGN CURRENCY TRANSLATION

The subsidiary located in Germany operates primarily using local functional currency. Accordingly, assets and liabilities of this subsidiary are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss.

DEFERRED RENT

Incentive payments received from landlords are recorded as deferred lease incentives and are amortized over the underlying lease term on a straight-line basis as a reduction of rent expense. When the terms of an operating lease provide for periods of free rent, rent concessions, and/or rent escalations, the Company establishes a deferred rent liability for the difference between the scheduled rent payment and the straight-line rent expense recognized. This deferred rent liability is amortized over the underlying lease term on a straight-line basis as a reduction of rent expense.

NET LOSS PER SHARE

Basic loss per share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution that could occur from common shares issuable through stock options, warrants and other convertible securities using the treasury stock method. The total amount of anti-dilutive options not included in the loss per share calculation for the years ended May 31, 2015 and 2014 were 1,148,000 and 860,500 respectively.

The following table illustrates the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations:

For the Years Ended May 31	2015		2014
Numerator for basic and diluted net loss per common share	$	(331,410)	$	(215,660)

 FS-11

SEGMENT REPORTING

ASC 280, “Segment Reporting” (ASC 280), establishes standards for reporting, by public business enterprises, information about operating segments, products and services, geographic areas, and major customers. The Company’s operations are analyzed by management and its chief operating decision maker as being part of a single industry segment: the design, development, marketing and sales of diagnostic kits.

REPORTING COMPREHENSIVE LOSS

Comprehensive loss represents net loss and any revenues, expenses, gains and losses that, under GAAP, are excluded from net loss and recognized directly as a component of shareholders’ equity. Accumulated other comprehensive loss consists solely of foreign currency translation adjustments.

RECENT ACCOUNTING PRONOUNCEMENTS

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-02: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”) which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012, which corresponded to the Company’s first quarter of fiscal 2014. Early adoption was permitted. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (“ASU 2013-04”). The amendments in ASU 2013-04 provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this update is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this standard are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013, which corresponds to the Company’s first quarter of fiscal 2015. The adoption of ASU 2013-04 did not have a material impact on the Company’s consolidated financial statements.

In March 2013, the FASB issued ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-05”). ASU 2013-05 clarifies that when a parent reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, the parent is required to apply the guidance in ASC 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013 which corresponds to the Company’s first quarter of fiscal 2015. Early adoption is permitted; however, if an entity elects to early adopt ASU 2013-05, it should be applied as of the beginning of the entity’s fiscal year of adoption. Prior periods should not be adjusted. The adoption of ASU 2013-05 did not have a material impact on the Company’s consolidated financial statements.

 FS-12

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” (ASU 2014-09).  ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services.  In adopting, ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach.  ASU 2014-09 is effective for the first interim period within annual reporting periods beginning December 15, 2016, and early adoption is not permitted.  Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2014-09 will have on the Company’s financial position or results of operations. During August 2015, the FASB voted to defer the effective date of the above mentioned revenue recognition guidance by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory.  ASU 2015-11 applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost.  An entity should measure inventory within the scope of ASU 2015-11 at the lower of cost and net realizable value.  Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.  The amendments in ASU 2015-11 more closely align the measurement of inventory in US GAAP with the measurement of inventory in International Financial Reporting Standards (“IFRS”).  ASU 2015-11 is effective for fiscal years beginning after December 31, 2016.  Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-11 will have on the Company’s financial position or results of operations.

Other recent ASU's issued by the FASB and guidance issued by the Securities and Exchange Commission did not, or are not believed by management to, have a material effect on the Company’s present or future consolidated financial statements.

During March 2014, the Company entered into a Small Business Banking Agreement with Union Bank for a one year business line of credit (the "Line") in the amount of $250,000. The interest rate for the line of credit was the prime rate in effect on the first day of the billing period, as published in the Wall Street Journal Prime West Coast Edition, plus a spread of 2.00%. Minimum monthly payments are the sum of (i) the amount of interest charge for the billing period, plus (ii) any amount past due, plus (iii) any fees, late charges and/or out-of-pocket expenses assessed. If the Line is not renewed as of the last day of the term of the Line, the entire unpaid balance of the Line, including unpaid fees and charges will be due and payable. The Company granted the bank security interest in the assets of the Company as collateral. The Line expired March 12, 2015 and was not renewed.  The Company is investigating other sources of operating capital to support its research activities.

Deferred tax assets, long-term portion		670,000		359,000
	$	744,000	$	446,000

The Company has provided a valuation allowance of $0 as of May 31, 2015 and 2014, respectively. The net change in the valuation allowance for the years ended May 31, 2015 and 2014 was a decrease of $0.

At May 31, 2015 and 2014, the Company has federal income tax net operating loss carryforwards of approximately $1,445,000 and $1,035,000 respectively. Of the reported net operating loss carryforwards, approximately $211,000 are related to windfall tax benefits from the exercise of the Company’s stock options by certain employees. Pursuant to ASC 718, the federal benefit of approximately $74,000 associated with this portion of the net operating loss will be credited to additional paid-in capital when the tax benefits are actually realized. The federal net operating loss carryforwards begin to expire in 2030. At May 31, 2015 and 2014, the Company has California state income tax net operating loss carryforwards of approximately $913,000 and $642,000, respectively.

At May 31, 2015, the Company has federal research and development tax credit carryforward of approximately $212,000.  The federal credits begin to expire in 2027.  The Company also had similar credit carryforwards for state purposes of $27,000 at May 31, 2015.

Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the Company's net operating loss ("NOL") and credit carryforwards may be limited by statute because of a cumulative change in ownership of more than 50%. Pursuant to Sections 382 and 383 of the Code, the annual use of the Company's NOLs would be limited if there is a cumulative change of ownership (as that term is defined in Section 382(g) of the Code) of greater than 50% in a three year period. Based on management's analysis the Company does not believe that a cumulative change in ownership of greater than 50% has taken place.

For the fiscal year ended May 31, 2015 and 2014, the Company did an analysis of its ASC 740 position and has not identified any uncertain tax positions as defined under ASC 740. Should such position be identified in the future and should the Company owe interest and penalties as a result of this, these would be recognized as interest expense and other expense, respectively, in the consolidated financial statements. The Company is no longer subject to any significant U.S. federal tax examinations by tax authorities for years before fiscal year 2011.

9.    COMMITMENTS AND CONTINGENCIES

OPERATING LEASES

On June 18, 2009 the Company entered into an agreement to lease a building in Irvine, California. The lease commenced September 1, 2009 and ends August 31, 2016.  The Company has an option to extend the term of its lease for two additional sixty month periods. The initial base rent was set at $18,490 per month increasing to $22,080 through August 31, 2016, with a security deposit of $22,080. The following is a schedule of rent payments due under the terms of the lease:

Years Ending May 31,
2016	$	263,031
2017		66,240
Total	$	329,271

According to the terms of the lease, the Company is also responsible for routine repairs of the building and for certain increases in property tax.

Total gross rent expense in the U.S. for fiscal 2015 and 2014 was $236,154 and $234,960, respectively.  Rent expense for the Mexico facility for fiscal 2015 and 2014 was $36,000 and $33,385 respectively.

The Company also has various insignificant leases for office equipment.

RETIREMENT SAVINGS PLAN

Effective September 1, 1986, the Company established a 401(k) plan for the benefit of its employees. The plan permits eligible employees to contribute to the plan up to the maximum percentage of total annual compensation allowable under the limits of Internal Revenue Code Sections 415, 401(k) and 404. The Company, at the discretion of its Board of Directors, may make contributions to the plan in amounts determined by the Board each year. No contributions by the Company have been made since the plan's inception.

FS-18
 

LITIGATION

The Company is, from time to time, involved in legal proceedings, claims and litigation arising in the ordinary course of business. While the amounts claimed may be substantial, the ultimate liability cannot presently be determined because of considerable uncertainties that exist. Therefore, it is possible the outcome of such legal proceedings, claims and litigation could have a material effect on quarterly or annual operating results or cash flows when resolved in a future period. However, based on facts currently available, management believes such matters will not have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows. There were no legal proceedings pending as of May 31, 2015.

CONTRACTS

On March 27, 2009, the Company signed an Asset Purchase Agreement with a European company for the purchase of certain technology related to the manufacture of certain medical diagnostic tests.  Consideration for this purchase was a nominal deposit upon signing the agreement and a nominal transfer fee upon successful commencement of production of the products.  A royalty shall be paid for five years beginning on the date of first sale of finished product derived from the purchased assets. Royalty payments of 10% of sales are due on these products for a period of five years.  Royalty expense for this license was approximately $1,400 and $600 for the years ended May 31, 2015 and 2014, respectively.

In October 2009, the Company entered into a non-exclusive, worldwide, perpetual, irrevocable, and transferable cross-license agreement to acquire technology and intellectual property from and make available its technology and intellectual property related to enzyme-linked immunosorbent assay products to be marketed by the Company. Pursuant to the terms of the license agreement, the Company has paid $25,000 for the license for each of six products, with a similar amount to be paid for each of two additional products as they are transferred. The Company will be amortizing the costs for these licenses over a ten year period. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% and is eligible to receive royalties from certain of its products licensed in the same percentages. The Company accrues this royalty when it becomes payable.  The Company had incurred approximately $15,000 in amortization of licensing fees during each fiscal year 2015 and 2014.

In May 2010, the Company acquired from an inventor the exclusive, perpetual license to a United States patent applicable to the measurement of thiopurine methyltransferase within patients prior to commencing treatment with thiopurine drugs. The product is currently being redeveloped by the Company. Pursuant to the terms of the license agreement, the Company was granted an exclusive, worldwide, perpetual license to manufacture, market, distribute and sell the products contemplated by the patents subject to the payment of $25,000 as reimbursement to the patent holder for legal and other costs associated with obtaining the patent, which was paid in June 2010. The Company is amortizing the initial cost of $25,000 for this license over a ten year period.  As of May 31, 2015, the Company had amortized $12,500 of the license. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% through September 30, 2022. The agreement also has minimum escalating royalty payments which must be made for the Company to keep its exclusivity for the license. The Company accrues this royalty when it becomes payable.  A credit to royalty expense in the amount of $8,300 was recorded in fiscal 2014 due to over accrual of such royalty. Royalty in the amount of $1,200 was recorded for the year ended May 31, 2015.  

 

On October 19, 2010, the Company signed an agreement with a university to acquire the rights to manufacture and market certain products using two patents owned by the university.  The Company paid a license issue fee of $15,000 initially and will pay royalties on net sales quarterly.  The Company has amortized the entire licensing fee as of May 31, 2013.   Royalty expense for this license was approximately $4,500 and $6,900 for the years ended May 31, 2015 and 2014, respectively.

The Company has two royalty agreements in which it has obtained rights to manufacture and market certain products for the life of the products. Royalty expense of approximately $21,000 is included in cost of sales for these agreements for each of the years ended May 31, 2015 and 2014. Beginning in fiscal 2011 the Company is only required to pay royalties for one of the products due to the fact that the company that was paid the royalties no longer provides materials to make that product, which was part of the original agreement. Sales of products manufactured under these agreements comprise approximately 3.2% and 3.0% of total sales for the years ended May 31, 2015 and 2014, respectively. The Company may license other products or technology in the future as it deems necessary for conducting business.

10.  SUBSEQUENT EVENT

During July 2015 the Board of Directors approved the execution of an agreement with an investment banker to raise up to $3.0 million via the sale of restricted common stock of the Company.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

12 Months Ended

May. 31, 2015

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

PRINCIPLES OF CONSOLIDATION 

The consolidated financial statements for the years ended May 31, 2015 and 2014 include the accounts of Biomerica, Inc. ("Biomerica") as well as its German subsidiary and Mexican subsidiary. The Mexican subsidiary has not begun operations. All significant intercompany accounts and transactions have been eliminated in consolidation.  

ACCOUNTING ESTIMATES 

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reported period. Actual results could materially differ from those estimates. 

FAIR VALUE OF FINANCIAL INSTRUMENTS 

The Company has financial instruments whereby the fair market value of the financial instruments could be different than that recorded on a historical basis. The Company's financial instruments consist of its cash and cash equivalents, accounts receivable, and accounts payable. The carrying amounts of the Company's financial instruments approximate their fair values. 

CONCENTRATION OF CREDIT RISK 

The Company maintains cash balances at certain financial institutions in excess of amounts insured by federal agencies. The Company does not believe it is exposed to any significant credit risks. 

The Company provides credit in the normal course of business to customers throughout the United States and foreign markets. For the years ended May 31, 2015 and 2014, the Company had one distributor which accounted for 16.3% and 23.4%, respectively, of consolidated sales. The Company performs ongoing credit evaluations of its customers and requires prepayment in some circumstances. At May 31, 2015, two customers accounted for 53.0% of gross accounts receivable. At May 31, 2014, two customers accounted for 60.5% of gross accounts receivable. 

For the year ended May 31, 2015, one company accounted for 13.6% of the purchases of raw materials. For the year ended May 31, 2014, two companies accounted for 30.2% of the purchases of raw materials. 

GEOGRAPHIC CONCENTRATION 

As of May 31, 2015 and 2014, approximately $530,000 and $443,000 of Biomerica's gross inventory and approximately $35,000 and $43,000, of Biomerica's property and equipment, net of accumulated depreciation and amortization, was located in Mexicali, Mexico, respectively. 

CASH EQUIVALENTS 

Cash and cash equivalents consist of demand deposits and money market accounts with original maturities of less than three months. 

ACCOUNTS RECEIVABLE 

The Company extends unsecured credit to its customers on a regular basis.  International accounts are required to prepay until they establish a history with the Company and at that time, they are extended credit at levels based on a number of criteria.  Credit levels are approved by designated upper level management.  Domestic customers are extended initial $500 credit limits until they establish a history with the Company or submit credit information.  All increases in credit limits are also approved by designated upper level management.  Management evaluates receivables on a quarterly basis and adjusts the allowance for doubtful accounts accordingly.  Balances over ninety days old are usually reserved for.    

Occasionally certain long-standing customers, who routinely place large orders, will have unusually large receivables balances relative to the total gross receivables.   Management monitors the payments for these large balances closely and very often requires payment of existing invoices before shipping new sales orders. 

INVENTORIES 

The Company values inventory at the lower of cost (determined using a combination of specific lot identification and the first-in, first-out methods) or market. Management periodically reviews inventory for excess quantities and obsolescence. Management evaluates quantities on hand, physical condition, and technical functionality as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. The reserve is adjusted based on such evaluation, with a corresponding provision included in cost of sales. Abnormal amounts of idle facility expenses, freight, handling costs and wasted material are recognized as current period charges and the allocation of fixed production overhead is based on the normal capacity of the production facilities.  

Inventories approximate the following at May 31: 

	2015		2014
Raw materials	$	958,000	$	899,000
Work in progress		831,000		635,000
Finished products		238,000		232,000
Total	$	2,027,000	$	1,766,000

Reserves for inventory obsolescence are recorded as necessary to reduce obsolete inventory to estimated net realizable value or to specifically reserve for obsolete inventory that the Company intends to dispose of. For the years ended May 31, 2015 and 2014 inventory reserves were approximately $25,000 and $43,000, respectively. 

PROPERTY AND EQUIPMENT 

Property and equipment are stated at cost. Expenditures for additions and major improvements are capitalized. Repairs and maintenance costs are charged to operations as incurred. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation or amortization are removed from the accounts, and gains or losses from retirements and dispositions are credited or charged to income. 

Depreciation and amortization are provided over the estimated useful lives of the related assets, ranging from 5 to 10 years, using the straight-line method. Leasehold improvements are amortized over the lesser of the estimated useful life of the asset or the term of the lease. Depreciation and amortization expense on property and equipment and leasehold improvements amounted to $178,219 and $177,518 for the years ended May 31, 2015 and 2014, respectively.  

INTANGIBLE ASSETS 

Intangible assets include trademarks, product rights, technology rights and patents, and are accounted for based on Accounting Standards Codification (“ASC”), ASC 350 “ Intangibles – Goodwill and Other ” (ASC 350). In that regard, intangible assets that have indefinite useful lives are not amortized but are tested at least annually for impairment or more frequently if events or changes in circumstances indicate that the asset might be impaired.  

Intangible assets are being amortized using the straight-line method over the useful life, not to exceed 18 years for marketing and distribution rights and purchased technology use rights, and 17 years for patents. Amortization amounted to $75,056 and $29,515 for the years ended May 31, 2015 and 2014, respectively. Intangible assets with indefinite lives such as perpetual licenses are not amortized but rather tested for impairment at least annually. 

The Company assesses the recoverability of these intangible assets by determining whether the amortization of the asset's balance over its remaining life can be recovered through projected undiscounted future cash flows. In July 2012,  the FASB issued another update to ASC 350  Intangibles – Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment . This update simplifies the guidance for testing impairment of indefinite-lived intangible assets other than goodwill. During fiscal 2013, the Company adopted the updated guidance in ASC 350 and used the qualitative assessment to determine whether there was any impairment. No impairment adjustment was required as of May 31, 2015. 

INVESTMENTS 

From time-to-time, the Company makes investments in privately-held companies.  The Company determines whether the fair values of any investments in privately-held entities have declined below their carrying value whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable.  If the Company considers any such decline to be other than temporary (based on various factors, including historical financial results, and the overall health of the investee’s industry), a write-down to estimated fair value is recorded. The Company currently has not written down the investment and no events have occurred which could indicate the carrying value to be less than the fair value. Investments represent the Company’s investment in a Polish distributor which is primarily engaged in distributing medical devices.  The Company owns approximately 6% of the investee, and accordingly, applies the cost method to account for the investment.  Under the cost method, investments are recorded at cost, with gains and losses recognized as of the sale date, and income recorded when received. 

SHARE-BASED COMPENSATION 

The Company follows the guidance of the accounting provisions of ASC 718 “ Share-based Compensation ” (ASC 718), which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (warrants and options). The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected forfeiture rate, expected term, and the risk-free interest rate. Expected volatilities are based on weighted averages of the historical volatility of the Company’s stock estimated over the expected term of the options. The expected forfeiture rate is based on historical forfeitures experienced. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term as historically the Company had limited activity surrounding its options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term.  

In applying the Black-Scholes options-pricing model, assumptions are as follows:   

	2015	2014
Dividend yield	0%	0%
Expected volatility	49.53-62.68%	48.65-49.85%
Risk free interest rate	1.26-1.67%	0.84-1.155%
Expected life	3.75-6.0 years	3.50 years

REVENUE RECOGNITION 

Revenues from product sales are recognized at the time the product is shipped, customarily FOB shipping point, at which point title passes. An allowance is established when necessary for estimated returns as revenue is recognized. As of May 31, 2015 and 2014, the allowance for returns is $0. 

SHIPPING AND HANDLING FEES AND COSTS 

Shipping and handling fees billed to customers are required to be classified as net sales, and shipping and handling costs are required to be classified as either cost of sales or disclosed in the notes to the financial statements. The Company included shipping and handling fees billed to customers in net sales. The Company included shipping and handling costs associated with inbound freight and unreimbursed shipping to customers in cost of sales. 

RESEARCH AND DEVELOPMENT 

Research and development costs are expensed as incurred. The Company expensed $733,640 and $589,866 of research and development expenses during the years ended May 31, 2015 and 2014, respectively. 

INCOME TAXES 

The Company accounts for income taxes in accordance with ASC 740, “ Income Taxes ” (ASC 740). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. These temporary differences are measured using enacted tax rates. A valuation allowance is recorded to reduce deferred tax assets to the extent that management considers it is more likely than not that a deferred tax asset will not be realized. In determining the valuation allowance, the Company considers factors such as the reversal of deferred income tax liabilities, projected taxable income, and the character of income tax assets and tax planning strategies. A change to these factors could impact the estimated valuation allowance and income tax expense.  

The Company accounts for its uncertain tax provisions by using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained in an audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the appropriate amount of the benefit to recognize. The amount of benefit to recognize is measured as the maximum amount which is more likely than not to be realized. The tax position is derecognized when it is no longer more likely than not capable of being sustained. On subsequent recognition and measurement the maximum amount which is more likely than not to be recognized at each reporting date will represent the Company’s best estimate, given the information available at the reporting date, although the outcome of the tax position is not absolute or final. Upon adopting the revisions in ASC 740, the Company elected to follow an accounting policy to classify accrued interest related to liabilities for income taxes within the “Interest expense” line and penalties related to liabilities for income taxes within the “Other expense” line of the consolidated statements of operations and comprehensive loss.  

ADVERTISING COSTS 

The Company reports the cost of all advertising as expense in the period in which those costs are incurred. Advertising costs were approximately $6,000 and $8,000 for the years ended May 31, 2015 and 2014, respectively. 

FOREIGN CURRENCY TRANSLATION 

The subsidiary located in Germany operates primarily using local functional currency. Accordingly, assets and liabilities of this subsidiary are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss.  

DEFERRED RENT 

Incentive payments received from landlords are recorded as deferred lease incentives and are amortized over the underlying lease term on a straight-line basis as a reduction of rent expense. When the terms of an operating lease provide for periods of free rent, rent concessions, and/or rent escalations, the Company establishes a deferred rent liability for the difference between the scheduled rent payment and the straight-line rent expense recognized. This deferred rent liability is amortized over the underlying lease term on a straight-line basis as a reduction of rent expense.   

NET LOSS PER SHARE 

Basic loss per share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution that could occur from common shares issuable through stock options, warrants and other convertible securities using the treasury stock method. The total amount of anti-dilutive options not included in the loss per share calculation for the years ended May 31, 2015 and 2014 were 1,148,000 and 860,500 respectively.  

The following table illustrates the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations: 

For the Years Ended May 31	2015		2014
Numerator for basic and diluted net loss per common share	$	(331,410)	$	(215,660)
Denominator for basic net loss per common share		7,552,262		7,370,787
Effect of dilutive securities:

Denominator for diluted net loss per common share		7,552,262		7,370,787
Basic net loss per common share	$	(0.04)	$	(0.03)
Diluted net loss per common share	$	(0.04)	$	(0.03)

SEGMENT REPORTING 

ASC 280, “ Segment Reporting ” (ASC 280), establishes standards for reporting, by public business enterprises, information about operating segments, products and services, geographic areas, and major customers. The Company’s operations are analyzed by management and its chief operating decision maker as being part of a single industry segment: the design, development, marketing and sales of diagnostic kits. 

REPORTING COMPREHENSIVE LOSS 

Comprehensive loss represents net loss and any revenues, expenses, gains and losses that, under GAAP, are excluded from net loss and recognized directly as a component of shareholders’ equity. Accumulated other comprehensive loss consists solely of foreign currency translation adjustments.  

RECENT ACCOUNTING PRONOUNCEMENTS 

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-02: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”) which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012, which corresponded to the Company’s first quarter of fiscal 2014. Early adoption was permitted. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. 

In February 2013, the FASB issued ASU No. 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (“ASU 2013-04”). The amendments in ASU 2013-04 provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this update is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this standard are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013, which corresponds to the Company’s first quarter of fiscal 2015. The adoption of ASU 2013-04 did not have a material impact on the Company’s consolidated financial statements. 

In March 2013, the FASB issued ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-05”). ASU 2013-05 clarifies that when a parent reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, the parent is required to apply the guidance in ASC 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013 which corresponds to the Company’s first quarter of fiscal 2015. Early adoption is permitted; however, if an entity elects to early adopt ASU 2013-05, it should be applied as of the beginning of the entity’s fiscal year of adoption. Prior periods should not be adjusted. The adoption of ASU 2013-05 did not have a material impact on the Company’s consolidated financial statements. 

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” (ASU 2014-09). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In adopting, ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. ASU 2014-09 is effective for the first interim period within annual reporting periods beginning December 15, 2016, and early adoption is not permitted. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2014-09 will have on the Company’s financial position or results of operations. During August 2015, the FASB voted to defer the effective date of the above mentioned revenue recognition guidance by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. 

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. An entity should measure inventory within the scope of ASU 2015-11 at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in ASU 2015-11 more closely align the measurement of inventory in US GAAP with the measurement of inventory in International Financial Reporting Standards (“IFRS”). ASU 2015-11 is effective for fiscal years beginning after December 31, 2016. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-11 will have on the Company’s financial position or results of operations. 

Other recent ASU's issued by the FASB and guidance issued by the Securities and Exchange Commission did not, or are not believed by management to, have a material effect on the Company’s present or future consolidated financial statements.

1.    ORGANIZATION  

Biomerica, Inc. and Subsidiaries (collectively "the Company") are primarily engaged in the development, manufacture and marketing of medical diagnostic kits.

The Company develops, manufactures, and markets medical diagnostic products designed for the early detection and monitoring of chronic diseases and medical conditions. The Company’s medical diagnostic products are sold worldwide in two markets: 1) clinical laboratories and 2) point of care (physicians' offices and over-the-counter drugstores). The diagnostic test kits are used to analyze blood, urine or fecal samples from patients in the diagnosis of various diseases and other medical complications, or to measure the level of specific hormones, antibodies, antigens or other substances, which may exist in the human body in extremely small concentrations.

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

PRINCIPLES OF CONSOLIDATION 

The consolidated financial statements for the years ended May 31, 2015 and 2014 include the accounts of Biomerica, Inc. ("Biomerica") as well as its German subsidiary and Mexican subsidiary. The Mexican subsidiary has not begun operations. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates, Policy [Policy Text Block]

ACCOUNTING ESTIMATES 

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reported period. Actual results could materially differ from those estimates.

Fair Value of Financial Instruments, Policy [Policy Text Block]

FAIR VALUE OF FINANCIAL INSTRUMENTS 

The Company has financial instruments whereby the fair market value of the financial instruments could be different than that recorded on a historical basis. The Company's financial instruments consist of its cash and cash equivalents, accounts receivable, and accounts payable. The carrying amounts of the Company's financial instruments approximate their fair values.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

CONCENTRATION OF CREDIT RISK 

The Company maintains cash balances at certain financial institutions in excess of amounts insured by federal agencies. The Company does not believe it is exposed to any significant credit risks. 

The Company provides credit in the normal course of business to customers throughout the United States and foreign markets. For the years ended May 31, 2015 and 2014, the Company had one distributor which accounted for 16.3% and 23.4%, respectively, of consolidated sales. The Company performs ongoing credit evaluations of its customers and requires prepayment in some circumstances. At May 31, 2015, two customers accounted for 53.0% of gross accounts receivable. At May 31, 2014, two customers accounted for 60.5% of gross accounts receivable. 

For the year ended May 31, 2015, one company accounted for 13.6% of the purchases of raw materials. For the year ended May 31, 2014, two companies accounted for 30.2% of the purchases of raw materials.

Concentration Risk Geographic Policy [Policy Text Block]

GEOGRAPHIC CONCENTRATION 

As of May 31, 2015 and 2014, approximately $530,000 and $443,000 of Biomerica's gross inventory and approximately $35,000 and $43,000, of Biomerica's property and equipment, net of accumulated depreciation and amortization, was located in Mexicali, Mexico, respectively.

Cash and Cash Equivalents, Policy [Policy Text Block]

CASH EQUIVALENTS 

Cash and cash equivalents consist of demand deposits and money market accounts with original maturities of less than three months.

Trade and Other Accounts Receivable, Policy [Policy Text Block]

ACCOUNTS RECEIVABLE 

The Company extends unsecured credit to its customers on a regular basis.  International accounts are required to prepay until they establish a history with the Company and at that time, they are extended credit at levels based on a number of criteria.  Credit levels are approved by designated upper level management.  Domestic customers are extended initial $500 credit limits until they establish a history with the Company or submit credit information.  All increases in credit limits are also approved by designated upper level management.  Management evaluates receivables on a quarterly basis and adjusts the allowance for doubtful accounts accordingly.  Balances over ninety days old are usually reserved for.    

Occasionally certain long-standing customers, who routinely place large orders, will have unusually large receivables balances relative to the total gross receivables.   Management monitors the payments for these large balances closely and very often requires payment of existing invoices before shipping new sales orders.

Inventory, Policy [Policy Text Block]

INVENTORIES 

The Company values inventory at the lower of cost (determined using a combination of specific lot identification and the first-in, first-out methods) or market. Management periodically reviews inventory for excess quantities and obsolescence. Management evaluates quantities on hand, physical condition, and technical functionality as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. The reserve is adjusted based on such evaluation, with a corresponding provision included in cost of sales. Abnormal amounts of idle facility expenses, freight, handling costs and wasted material are recognized as current period charges and the allocation of fixed production overhead is based on the normal capacity of the production facilities.  

Inventories approximate the following at May 31: 

	2015		2014
Raw materials	$	958,000	$	899,000
Work in progress		831,000		635,000
Finished products		238,000		232,000
Total	$	2,027,000	$	1,766,000

Reserves for inventory obsolescence are recorded as necessary to reduce obsolete inventory to estimated net realizable value or to specifically reserve for obsolete inventory that the Company intends to dispose of. For the years ended May 31, 2015 and 2014 inventory reserves were approximately $25,000 and $43,000, respectively.

Property, Plant and Equipment, Policy [Policy Text Block]

PROPERTY AND EQUIPMENT 

Property and equipment are stated at cost. Expenditures for additions and major improvements are capitalized. Repairs and maintenance costs are charged to operations as incurred. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation or amortization are removed from the accounts, and gains or losses from retirements and dispositions are credited or charged to income. 

Depreciation and amortization are provided over the estimated useful lives of the related assets, ranging from 5 to 10 years, using the straight-line method. Leasehold improvements are amortized over the lesser of the estimated useful life of the asset or the term of the lease. Depreciation and amortization expense on property and equipment and leasehold improvements amounted to $178,219 and $177,518 for the years ended May 31, 2015 and 2014, respectively.

Intangible Assets, Finite-Lived, Policy [Policy Text Block]

INTANGIBLE ASSETS 

Intangible assets include trademarks, product rights, technology rights and patents, and are accounted for based on Accounting Standards Codification (“ASC”), ASC 350 “ Intangibles – Goodwill and Other ” (ASC 350). In that regard, intangible assets that have indefinite useful lives are not amortized but are tested at least annually for impairment or more frequently if events or changes in circumstances indicate that the asset might be impaired.  

Intangible assets are being amortized using the straight-line method over the useful life, not to exceed 18 years for marketing and distribution rights and purchased technology use rights, and 17 years for patents. Amortization amounted to $75,056 and $29,515 for the years ended May 31, 2015 and 2014, respectively. Intangible assets with indefinite lives such as perpetual licenses are not amortized but rather tested for impairment at least annually. 

The Company assesses the recoverability of these intangible assets by determining whether the amortization of the asset's balance over its remaining life can be recovered through projected undiscounted future cash flows. In July 2012,  the FASB issued another update to ASC 350  Intangibles – Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment . This update simplifies the guidance for testing impairment of indefinite-lived intangible assets other than goodwill. During fiscal 2013, the Company adopted the updated guidance in ASC 350 and used the qualitative assessment to determine whether there was any impairment. No impairment adjustment was required as of May 31, 2015.

From time-to-time, the Company makes investments in privately-held companies.  The Company determines whether the fair values of any investments in privately-held entities have declined below their carrying value whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable.  If the Company considers any such decline to be other than temporary (based on various factors, including historical financial results, and the overall health of the investee’s industry), a write-down to estimated fair value is recorded. The Company currently has not written down the investment and no events have occurred which could indicate the carrying value to be less than the fair value. Investments represent the Company’s investment in a Polish distributor which is primarily engaged in distributing medical devices.  The Company owns approximately 6% of the investee, and accordingly, applies the cost method to account for the investment.  Under the cost method, investments are recorded at cost, with gains and losses recognized as of the sale date, and income recorded when received.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

SHARE-BASED COMPENSATION 

The Company follows the guidance of the accounting provisions of ASC 718 “ Share-based Compensation ” (ASC 718), which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (warrants and options). The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected forfeiture rate, expected term, and the risk-free interest rate. Expected volatilities are based on weighted averages of the historical volatility of the Company’s stock estimated over the expected term of the options. The expected forfeiture rate is based on historical forfeitures experienced. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term as historically the Company had limited activity surrounding its options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term.  

In applying the Black-Scholes options-pricing model, assumptions are as follows:   

	2015	2014
Dividend yield	0%	0%
Expected volatility	49.53-62.68%	48.65-49.85%
Risk free interest rate	1.26-1.67%	0.84-1.155%
Expected life	3.75-6.0 years	3.50 years

Revenue Recognition, Policy [Policy Text Block]

REVENUE RECOGNITION 

Revenues from product sales are recognized at the time the product is shipped, customarily FOB shipping point, at which point title passes. An allowance is established when necessary for estimated returns as revenue is recognized. As of May 31, 2015 and 2014, the allowance for returns is $0.

Shipping and Handling Cost, Policy [Policy Text Block]

SHIPPING AND HANDLING FEES AND COSTS 

Shipping and handling fees billed to customers are required to be classified as net sales, and shipping and handling costs are required to be classified as either cost of sales or disclosed in the notes to the financial statements. The Company included shipping and handling fees billed to customers in net sales. The Company included shipping and handling costs associated with inbound freight and unreimbursed shipping to customers in cost of sales.

Research and Development Expense, Policy [Policy Text Block]

RESEARCH AND DEVELOPMENT 

Research and development costs are expensed as incurred. The Company expensed $733,640 and $589,866 of research and development expenses during the years ended May 31, 2015 and 2014, respectively.

Income Tax, Policy [Policy Text Block]

INCOME TAXES 

The Company accounts for income taxes in accordance with ASC 740, “ Income Taxes ” (ASC 740). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. These temporary differences are measured using enacted tax rates. A valuation allowance is recorded to reduce deferred tax assets to the extent that management considers it is more likely than not that a deferred tax asset will not be realized. In determining the valuation allowance, the Company considers factors such as the reversal of deferred income tax liabilities, projected taxable income, and the character of income tax assets and tax planning strategies. A change to these factors could impact the estimated valuation allowance and income tax expense.  

The Company accounts for its uncertain tax provisions by using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained in an audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the appropriate amount of the benefit to recognize. The amount of benefit to recognize is measured as the maximum amount which is more likely than not to be realized. The tax position is derecognized when it is no longer more likely than not capable of being sustained. On subsequent recognition and measurement the maximum amount which is more likely than not to be recognized at each reporting date will represent the Company’s best estimate, given the information available at the reporting date, although the outcome of the tax position is not absolute or final. Upon adopting the revisions in ASC 740, the Company elected to follow an accounting policy to classify accrued interest related to liabilities for income taxes within the “Interest expense” line and penalties related to liabilities for income taxes within the “Other expense” line of the consolidated statements of operations and comprehensive loss.

Advertising Costs, Policy [Policy Text Block]

ADVERTISING COSTS 

The Company reports the cost of all advertising as expense in the period in which those costs are incurred. Advertising costs were approximately $6,000 and $8,000 for the years ended May 31, 2015 and 2014, respectively.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

FOREIGN CURRENCY TRANSLATION 

The subsidiary located in Germany operates primarily using local functional currency. Accordingly, assets and liabilities of this subsidiary are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss.

Deferred Charges, Policy [Policy Text Block]

DEFERRED RENT 

Incentive payments received from landlords are recorded as deferred lease incentives and are amortized over the underlying lease term on a straight-line basis as a reduction of rent expense. When the terms of an operating lease provide for periods of free rent, rent concessions, and/or rent escalations, the Company establishes a deferred rent liability for the difference between the scheduled rent payment and the straight-line rent expense recognized. This deferred rent liability is amortized over the underlying lease term on a straight-line basis as a reduction of rent expense.

Earnings Per Share, Policy [Policy Text Block]

NET LOSS PER SHARE 

Basic loss per share is computed as net loss divided by the weighted average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution that could occur from common shares issuable through stock options, warrants and other convertible securities using the treasury stock method. The total amount of anti-dilutive options not included in the loss per share calculation for the years ended May 31, 2015 and 2014 were 1,148,000 and 860,500 respectively.  

The following table illustrates the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations: 

For the Years Ended May 31	2015		2014
Numerator for basic and diluted net loss per common share	$	(331,410)	$	(215,660)

Segment Reporting, Policy [Policy Text Block]

SEGMENT REPORTING 

ASC 280, “ Segment Reporting ” (ASC 280), establishes standards for reporting, by public business enterprises, information about operating segments, products and services, geographic areas, and major customers. The Company’s operations are analyzed by management and its chief operating decision maker as being part of a single industry segment: the design, development, marketing and sales of diagnostic kits.

Comprehensive Income, Policy [Policy Text Block]

REPORTING COMPREHENSIVE LOSS 

Comprehensive loss represents net loss and any revenues, expenses, gains and losses that, under GAAP, are excluded from net loss and recognized directly as a component of shareholders’ equity. Accumulated other comprehensive loss consists solely of foreign currency translation adjustments.

New Accounting Pronouncements, Policy [Policy Text Block]

RECENT ACCOUNTING PRONOUNCEMENTS 

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-02: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”) which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012, which corresponded to the Company’s first quarter of fiscal 2014. Early adoption was permitted. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. 

In February 2013, the FASB issued ASU No. 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (“ASU 2013-04”). The amendments in ASU 2013-04 provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this update is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this standard are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013, which corresponds to the Company’s first quarter of fiscal 2015. The adoption of ASU 2013-04 did not have a material impact on the Company’s consolidated financial statements. 

In March 2013, the FASB issued ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-05”). ASU 2013-05 clarifies that when a parent reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, the parent is required to apply the guidance in ASC 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013 which corresponds to the Company’s first quarter of fiscal 2015. Early adoption is permitted; however, if an entity elects to early adopt ASU 2013-05, it should be applied as of the beginning of the entity’s fiscal year of adoption. Prior periods should not be adjusted. The adoption of ASU 2013-05 did not have a material impact on the Company’s consolidated financial statements. 

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” (ASU 2014-09). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In adopting, ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. ASU 2014-09 is effective for the first interim period within annual reporting periods beginning December 15, 2016, and early adoption is not permitted. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2014-09 will have on the Company’s financial position or results of operations. During August 2015, the FASB voted to defer the effective date of the above mentioned revenue recognition guidance by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. 

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. An entity should measure inventory within the scope of ASU 2015-11 at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in ASU 2015-11 more closely align the measurement of inventory in US GAAP with the measurement of inventory in International Financial Reporting Standards (“IFRS”). ASU 2015-11 is effective for fiscal years beginning after December 31, 2016. Management is evaluating the provisions of this statement and has not determined what impact the adoption of ASU 2015-11 will have on the Company’s financial position or results of operations. 

Other recent ASU's issued by the FASB and guidance issued by the Securities and Exchange Commission did not, or are not believed by management to, have a material effect on the Company’s present or future consolidated financial statements.

5.    DEBT 

During March 2014, the Company entered into a Small Business Banking Agreement with Union Bank for a one year business line of credit (the "Line") in the amount of $250,000. The interest rate for the line of credit was the prime rate in effect on the first day of the billing period, as published in the Wall Street Journal Prime West Coast Edition, plus a spread of 2.00%. Minimum monthly payments are the sum of (i) the amount of interest charge for the billing period, plus (ii) any amount past due, plus (iii) any fees, late charges and/or out-of-pocket expenses assessed. If the Line is not renewed as of the last day of the term of the Line, the entire unpaid balance of the Line, including unpaid fees and charges will be due and payable. The Company granted the bank security interest in the assets of the Company as collateral. The Line expired March 12, 2015 and was not renewed. The Company is investigating other sources of operating capital to support its research activities.

The Company has provided a valuation allowance of $0 as of May 31, 2015 and 2014, respectively. The net change in the valuation allowance for the years ended May 31, 2015 and 2014 was a decrease of $0. 

At May 31, 2015 and 2014, the Company has federal income tax net operating loss carryforwards of approximately $1,445,000 and $1,035,000 respectively. Of the reported net operating loss carryforwards, approximately $211,000 are related to windfall tax benefits from the exercise of the Company’s stock options by certain employees. Pursuant to ASC 718, the federal benefit of approximately $74,000 associated with this portion of the net operating loss will be credited to additional paid-in capital when the tax benefits are actually realized. The federal net operating loss carryforwards begin to expire in 2030. At May 31, 2015 and 2014, the Company has California state income tax net operating loss carryforwards of approximately $913,000 and $642,000, respectively. 

At May 31, 2015, the Company has federal research and development tax credit carryforward of approximately $212,000.  The federal credits begin to expire in 2027.  The Company also had similar credit carryforwards for state purposes of $27,000 at May 31, 2015. 

Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the Company's net operating loss ("NOL") and credit carryforwards may be limited by statute because of a cumulative change in ownership of more than 50%. Pursuant to Sections 382 and 383 of the Code, the annual use of the Company's NOLs would be limited if there is a cumulative change of ownership (as that term is defined in Section 382(g) of the Code) of greater than 50% in a three year period. Based on management's analysis the Company does not believe that a cumulative change in ownership of greater than 50% has taken place. 

For the fiscal year ended May 31, 2015 and 2014, the Company did an analysis of its ASC 740 position and has not identified any uncertain tax positions as defined under ASC 740. Should such position be identified in the future and should the Company owe interest and penalties as a result of this, these would be recognized as interest expense and other expense, respectively, in the consolidated financial statements. The Company is no longer subject to any significant U.S. federal tax examinations by tax authorities for years before fiscal year 2011.

9.    COMMITMENTS AND CONTINGENCIES 

OPERATING LEASES 

On June 18, 2009 the Company entered into an agreement to lease a building in Irvine, California. The lease commenced September 1, 2009 and ends August 31, 2016. The Company has an option to extend the term of its lease for two additional sixty month periods. The initial base rent was set at $18,490 per month increasing to $22,080 through August 31, 2016, with a security deposit of $22,080.  The following is a schedule of rent payments due under the terms of the lease: 

Years Ending May 31,
2016	$	263,031
2017		66,240
Total	$	329,271

According to the terms of the lease, the Company is also responsible for routine repairs of the building and for certain increases in property tax.  

Total gross rent expense in the U.S. for fiscal 2015 and 2014 was $236,154 and $234,960, respectively.  Rent expense for the Mexico facility for fiscal 2015 and 2014 was $36,000 and $33,385 respectively. 

The Company also has various insignificant leases for office equipment. 

RETIREMENT SAVINGS PLAN 

Effective September 1, 1986, the Company established a 401(k) plan for the benefit of its employees. The plan permits eligible employees to contribute to the plan up to the maximum percentage of total annual compensation allowable under the limits of Internal Revenue Code Sections 415, 401(k) and 404. The Company, at the discretion of its Board of Directors, may make contributions to the plan in amounts determined by the Board each year. No contributions by the Company have been made since the plan's inception. 

LITIGATION 

The Company is, from time to time, involved in legal proceedings, claims and litigation arising in the ordinary course of business. While the amounts claimed may be substantial, the ultimate liability cannot presently be determined because of considerable uncertainties that exist. Therefore, it is possible the outcome of such legal proceedings, claims and litigation could have a material effect on quarterly or annual operating results or cash flows when resolved in a future period. However, based on facts currently available, management believes such matters will not have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows. There were no legal proceedings pending as of May 31, 2015. 

CONTRACTS 

On March 27, 2009, the Company signed an Asset Purchase Agreement with a European company for the purchase of certain technology related to the manufacture of certain medical diagnostic tests.  Consideration for this purchase was a nominal deposit upon signing the agreement and a nominal transfer fee upon successful commencement of production of the products.  A royalty shall be paid for five years beginning on the date of first sale of finished product derived from the purchased assets. Royalty payments of 10% of sales are due on these products for a period of five years.  Royalty expense for this license was approximately $1,400 and $600 for the years ended May 31, 2015 and 2014, respectively. 

In October 2009, the Company entered into a non-exclusive, worldwide, perpetual, irrevocable, and transferable cross-license agreement to acquire technology and intellectual property from and make available its technology and intellectual property related to enzyme-linked immunosorbent assay products to be marketed by the Company. Pursuant to the terms of the license agreement, the Company has paid $25,000 for the license for each of six products, with a similar amount to be paid for each of two additional products as they are transferred. The Company will be amortizing the costs for these licenses over a ten year period. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% and is eligible to receive royalties from certain of its products licensed in the same percentages. The Company accrues this royalty when it becomes payable.  The Company had incurred approximately $15,000 in amortization of licensing fees during each fiscal year 2015 and 2014. 

In May 2010, the Company acquired from an inventor the exclusive, perpetual license to a United States patent applicable to the measurement of thiopurine methyltransferase within patients prior to commencing treatment with thiopurine drugs. The product is currently being redeveloped by the Company. Pursuant to the terms of the license agreement, the Company was granted an exclusive, worldwide, perpetual license to manufacture, market, distribute and sell the products contemplated by the patents subject to the payment of $25,000 as reimbursement to the patent holder for legal and other costs associated with obtaining the patent, which was paid in June 2010. The Company is amortizing the initial cost of $25,000 for this license over a ten year period.  As of May 31, 2015, the Company had amortized $12,500 of the license. As part of this agreement, the Company must pay royalties on future sales of these products between 4% and 8% through September 30, 2022. The agreement also has minimum escalating royalty payments which must be made for the Company to keep its exclusivity for the license. The Company accrues this royalty when it becomes payable.  A credit to royalty expense in the amount of $8,300 was recorded in fiscal 2014 due to over accrual of such royalty. Royalty in the amount of $1,200 was recorded for the year ended May 31, 2015.    

On October 19, 2010, the Company signed an agreement with a university to acquire the rights to manufacture and market certain products using two patents owned by the university.  The Company paid a license issue fee of $15,000 initially and will pay royalties on net sales quarterly.  The Company has amortized the entire licensing fee as of May 31, 2013.   Royalty expense for this license was approximately $4,500 and $6,900 for the years ended May 31, 2015 and 2014, respectively. 

The Company has two royalty agreements in which it has obtained rights to manufacture and market certain products for the life of the products. Royalty expense of approximately $21,000 is included in cost of sales for these agreements for each of the years ended May 31, 2015 and 2014. Beginning in fiscal 2011 the Company is only required to pay royalties for one of the products due to the fact that the company that was paid the royalties no longer provides materials to make that product, which was part of the original agreement. Sales of products manufactured under these agreements comprise approximately 3.2% and 3.0% of total sales for the years ended May 31, 2015 and 2014, respectively. The Company may license other products or technology in the future as it deems necessary for conducting business.
