PART I

ITEM 1. BUSINESS

OVERVIEW

TECHNE Corporation was incorporated on July 17, 1981 in the state of Minnesota. TECHNE Corporation and subsidiaries (the Company) are engaged in the development, manufacture and sale of biotechnology products and hematology calibrators and controls. These activities are conducted domestically through its wholly-owned subsidiaries, Research and Diagnostic Systems, Inc. (R&D Systems), Boston Biochem, Inc. (Boston Biochem), Tocris Cookson, Inc. (Tocris US), and BiosPacific, Inc. (BiosPacific). The Company’s European biotechnology operations are conducted through its wholly-owned U.K. subsidiaries, R&D Systems Europe Ltd. (R&D Europe) and Tocris Holdings Limited (Tocris UK). R&D Europe has a sales subsidiary, R&D Systems GmbH, in Germany and a sales office in France. The Company distributes its biotechnology products in China through its wholly-owned subsidiary, R&D Systems China Co., Ltd. (R&D China). R&D China has a sales subsidiary, R&D Systems Hong Kong Ltd., in Hong Kong.

On April 1, 2011, the Company acquired for approximately $7.9 million cash, the assets of Boston Biochem, Inc., a leading developer and manufacturer of innovative ubiquitin-related research products. These products provide biomedical researchers the tools that facilitate and accelerate basic research and drug discovery efforts. Boston Biochem was founded in 1997 and currently has over 800 ubiquitin-related products. The Ubiquitin Proteasome Pathway is the principal system for protein degradation and signaling in eukaryotic cells. Ubiquitination also affects proteasome-independent events such as protein localization, activity and function. These pathways are central to the regulation of almost all cellular processes. Ubiquitin and related pathways are associated with the regulation of numerous disease states including multiple cancers, diabetes, Parkinson’s, Alzheimer’s, cystic fibrosis, Angelman’s syndrome, Liddle syndrome and Wilson’s disease.

On April 28, 2011, the Company acquired for £75.0 million cash (approximately $124 million), 100% ownership of Tocris Holdings Limited and subsidiaries (Tocris), a leading supplier of reagents for non-clinical life science research. Pursuant to the purchase agreement, £7.5 million of the purchase price paid to Tocris’ shareholders is being held in escrow for 18 months to secure warranty and indemnity obligations of the shareholders. Tocris’ products are used in both in-vitro and in-vivo experiments, to understand biological processes and diseases. The business is focused on making biologically active chemicals which are used by researchers to elucidate biological processes and pathways. The products are used in life-science research activities and as part of the initial drug discovery process. Tocris is a Bristol, U.K. based company with origins deriving from Tocris Neuramin and Cookson Chemical, which were founded in 1982 and 1985, respectively. Tocris currently offers over 2,900 chemical, peptide and antibody products. The principal end users are non-clinical laboratory based researchers, working in areas such as neuroscience, cardiovascular disease, endocrinology and cellular processes. Originally a supplier of small molecules, Tocris has successfully pursued a strategy of extending its product range into related market segments such as signal transduction. The products sold by Tocris are used in various research fields including cancer, cardiovascular disease, endocrinology, immunology, metabolic diseases, neurological diseases, pain and inflammation, and respiratory diseases. From a cellular process perspective, Tocris products are used to study angiogenesis, apoptosis, cell cycle, cell metabolism, cellular skeleton and motor proteins, extracellular matrix, adhesion molecules, signal transduction and stem cells. Tocris reagents are also used from a pharmacological perspective to study ion channels, 7-TM receptors, nuclear receptors, enzyme-linked receptors, transporter molecules and enzymes.

Table of Contents

As a result of the above acquisitions, the Company has changed the presentation of its segment disclosure from three reporting segments (biotechnology, R&D Europe and hematology) to two reporting segments (biotechnology and hematology). R&D Systems’ Biotechnology Division, R&D Europe, Tocris, R&D China, BiosPacific and Boston Biochem operating segments are included in the biotechnology reporting segment. The Company’s biotechnology reporting segment develops, manufactures and sells biotechnology research and diagnostic products world-wide. The Company’s hematology reporting segment, which consists of R&D Systems’ Hematology Division, develops and manufactures hematology controls and calibrators for sale world-wide. Corresponding items of segment information have been revised for prior periods to conform to the current year presentation.

THE MARKET

The Company manufactures and sells products for the biotechnology research market and the clinical diagnostics market. In fiscal 2011, 2010 and 2009, net sales from the Company’s biotechnology segment were 93% of consolidated net sales in each year. The Company’s hematology segment net sales were 7% of consolidated net sales for each of fiscal 2011, 2010 and 2009. Financial information relating to the Company’s segments is incorporated herein by reference to Note M to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Biotechnology segment

The Company, through its biotechnology segment, is one of the world’s leading suppliers of specialized proteins, such as cytokines and related reagents, to the biotechnology research community. These valuable proteins are produced in minute amounts by different types of cells and can be isolated from these cells or synthesized through recombinant DNA technology. Currently nearly all of the Company’s proteins are produced by recombinant DNA technology.

The growing interest by academic and commercial researchers in cytokines is largely due to the profound effect that a tiny amount of a cytokine can have on cells and tissues. Cytokines are intercellular messengers. They act as signals by interacting with specific receptors on the affected cells and trigger events that can lead to significant changes in a cell, tissue or organism. For example, cytokines can signal a cell to acquire the features necessary for it to take on a more specialized task. Another example of cytokine action is the key role played in stimulating cells surrounding a wound to grow and divide, to attract migratory cells to the injury site and mediate the healing process.

The Company also has enzymes and intracellular cell signaling reagents in its product portfolio. Enzymes are proteins which act as biological catalysts that accelerate a variety of chemical reactions in cells. Most enzymes, including proteases, kinases and phosphatases, are proteins that modify the structure and function of other proteins. Additionally, both enzymes and cytokines have the potential to serve as predictive biomarkers and therapeutic targets for a variety of diseases and conditions including cancer, Alzheimer’s, arthritis, autoimmunity, diabetes, hypertension, obesity, inflammation, AIDS and influenza.

The Company markets one type of immunoassay kit under the trade name Quantikine^®. Quantikine kits are used by researchers to quantify the level of a specific protein in biological fluids, such as serum, plasma, or urine. Protein quantification is an integral component of basic research and as a valuable indicator of the effects of new compounds as candidates in the pharmaceutical drug discovery and development process.

With the acquisition of Tocris in April 2011, the Company added chemically-based products to its biotechnology segment. Tocris products are chemically-based small compounds, sold in highly purified forms and with agonistic or antagonistic properties in a variety of biological processes. The addition of Tocris products to the Company’s product lines allows customers to have access to the broadest range of compounds and biological reagents to meet their life science research needs. The combined chemical and biological reagents portfolio of the two companies provide new tools which can be used in solving the complexity of important biological pathways and glean knowledge which may lead to a fuller understanding of biological processes and ultimately the development of novel strategies to address different pathologies.

The Company currently manufactures and sells over 20,000 biotechnology products.

Biotechnology Products

Proteins. Cytokines and enzymes, extracted from natural sources or produced using recombinant DNA technology, are manufactured to the highest possible purity. Proteins, including enzyme substrates and inhibitors, are highly purified and characterized to ensure the highest biological activity.

Antibodies. Antibodies are specialized proteins produced by the immune system of an animal that recognize and bind to target molecules. The Company’s polyclonal antibodies are produced in animals (primarily goats, sheep and rabbits) and purified from the animals’ blood. Monoclonal antibodies are derived from immortalized rodent cell lines and are isolated from cell culture medium.

Immunoassays. The immunoassay product line includes Quantikine kits for the detection of human and animal proteins using 96-well plates, along with immunoassays on other testing platforms, which allow researchers to quantify the amount of a specific analyte (typically a cytokine, adhesion molecule or an enzyme) in a sample derived from any biological fluid.

Clinical Diagnostic Immunoassay Kits. The Company has received Food and Drug Administration (FDA) marketing clearance for its erythropoietin (EPO), transferrin receptor (TfR) and Beta2-microglobulin immunoassays for use as in vitro diagnostic devices.

Flow Cytometry Products. This product line includes fluorochrome labeled antibodies and kits, which are used to determine the immuno-phenotypic properties of cells from different tissues.

Intracellular Cell Signaling Products. This diverse product line provides reagents to elucidate cell signal transduction pathways within cells. Products include antibodies, phospho-specific antibodies, antibody arrays, active caspases, kinases, and phosphatases, and ELISA assays to measure the activity of apoptotic and signaling molecules.

Chemically-based Products. These products include small natural or synthetic chemical compounds used by investigators as agonists, antagonists and/or inhibitors of various biological functions. Used in concert with other Company products, they provide additional tools to elucidate key pathways of cellular functions and can provide insight into the drug discovery process.

The Company sells its biotechnology products directly to customers in North America, most of Western Europe and to certain customers in China. Third party distributors are used in the remainder of China and Europe and in the rest of the world.

Hematology segment

Hematology controls and calibrators are products derived from various cellular components of blood which have been stabilized. Proper diagnosis of many illnesses requires a thorough and accurate analysis of a patient’s blood cells, which is usually done with automated or semi-automated hematology instruments. Controls and calibrators ensure that these instruments are performing accurately and reliably.

Table of Contents

Blood is composed of plasma, the fluid portion of blood, and blood cells, which are suspended in the plasma. There are three basic types of blood cells: red cells, white cells and platelets. Hemoglobin in red cells transports oxygen from the lungs throughout the body. White cells are part of the body’s immune system. Platelets serve as a “plug” to stem blood flow at the site of an injury by initiating a complex series of biochemical reactions that lead to the formation of a clot.

These fundamental blood components (red cells, white cells and platelets) differ widely in size and concentration. As noted above, hematology controls are used in automated and semi-automated cell counting analyzers to make sure these instruments are counting blood cells in patient samples accurately. One of the most frequently performed laboratory tests on a blood sample is a complete blood count (CBC). Doctors use this rapid test in disease screening and diagnosis. More than one billion of these tests are done world-wide every year, the great majority with cell counting instruments. In most laboratories, the CBC consists of the white cell count, the red cell count, the hemoglobin reading, and the hematocrit reading (the percent of red cells in a volume of whole blood after it has been centrifuged). Also included in a CBC test is the differential, which numbers and classifies the different types of white blood cells.

These and other characteristics or “parameters” of a blood sample can be measured by automated or semi-automated cell counters. The number of parameters measurable in a blood control product depends on the type and sophistication of the instrument for which the control is designed. Ordinarily, a hematology control is used once to several times a day to make sure the instrument is reading accurately. In addition, most instruments need to be calibrated periodically. Hematology calibrators are similar to controls, but undergo additional testing to ensure that the calibration values assigned are within tight specifications and can be used to calibrate the instrument.

The Company offers a wide range of hematology controls and calibrators for both impedance and laser type cell counters. The Company believes its products have improved stability and versatility and a longer shelf life than most of those of its competitors. Hematology control products are also supplied for use as proficiency testing tools by laboratory certifying authorities in a number of states and countries.

Hematology Products

Whole Blood CBC Controls/Calibrators. The Company currently produces controls and calibrators for the following major brands of analyzers: Abbott Diagnostics, Beckman Coulter, Siemens Healthcare Diagnostics, HORIBA Medical and Sysmex.

Linearity and Reportable Range Controls. These products provide a means of assessing the linearity of hematology analyzers for white blood cells, red blood cells, platelets and reticulocytes (immature red blood cells). Because hematology analyzers are single-point calibrated, these products allow users to determine and validate the reportable range of an instrument.

Whole Blood Reticulocyte Controls. These controls are designed for manual and automated counting of reticulocytes (immature red blood cells).

Whole Blood Flow Cytometry Controls. These products act as controls for clinical flow cytometry instruments. These instruments are used to identify and quantify white blood cells by their immuno-phenotypic properties.

Whole Blood Glucose/Hemoglobin Control. This product is designed to monitor instruments which measure glucose and hemoglobin in whole blood.

Erythrocyte Sedimentation Rate Control. This product is designed to monitor erythrocyte (red blood cell) sedimentation rate tests.

Multi-Purpose Platelet Reference Controls. These products, Platelet-Trol^® II and Platelet-Trol Extended, are designed for use by automated and semi-automated analyzers which monitor platelet levels.

Original Equipment Manufacturer (OEM) agreements represent the largest market for hematology controls and calibrators made by the Company. In fiscal 2011, 2010 and 2009, OEM agreements accounted for $8.7 million, $8.0 million and $7.6 million, respectively, or 3% of total consolidated net sales in each fiscal year. The Company sells directly to customers in the United States and through distributors in the rest of the world.

PRODUCTS UNDER DEVELOPMENT

The Company is engaged in ongoing research and development in all of its major product lines: controls and calibrators (hematology) and cytokines, antibodies, assays and related products (biotechnology). The Company believes that its future success depends, to a large extent, on its ability to keep pace with changing technologies and markets. At the same time, the Company continues to examine its production processes to ensure high quality and maximum efficiency.

In fiscal 2011, the Company introduced 1,646 new biotechnology products. The Company is planning to release new proteins, antibodies, immunoassay products and chemically-based research reagents in the coming year. All of these products will be for research purposes only and therefore do not require FDA clearance. The Company also developed several new hematology control products in fiscal 2011 and is continuously working on product improvements and enhancements. However, there is no assurance that any of the products in the research and development phase can be successfully completed or, if completed, can be successfully introduced into the marketplace.

INVESTMENTS

The Company has invested in the preferred stock of ChemoCentryx, Inc. (CCX). CCX is a technology and drug development company working in the area of chemokines. Chemokines are cytokines which regulate the trafficking patterns of leukocytes, the effector cells of the human immune system. In conjunction with the investment and joint research efforts, the Company obtained exclusive worldwide research and diagnostic marketing rights to chemokine proteins, antibodies and receptors discovered or developed by CCX. The Company holds a 16.6% ownership percentage in CCX. The Company has evaluated the cost versus equity method of accounting for its investment in CCX and determined that it does not have the ability to exercise significant influence over the operating and financial policies of CCX and therefore, accounts for its investment on a cost basis. The Company’s net investment in CCX at both June 30, 2011 and 2010 was $14.3 million.

The Company has an 8.3% ownership percentage in Hemerus Medical, LLC (Hemerus). Hemerus was formed in March 2001 and has acquired and is developing technology for the separation of leukocytes from red blood cells and to extend the shelf life of the isolated blood products. Hemerus owns two patents, has several patent applications pending and has received FDA clearance to market its products in the U.S. In parallel with this investment, R&D Systems entered into a Joint Research Agreement with Hemerus. The research involves joint projects to explore the use of Hemerus’ filter technology to applications within R&D Systems’ Hematology and Biotechnology Divisions. Such applications, if any, may have commercial potential in other laboratory environments. The Company accounts for its investment in Hemerus under the equity method of accounting as Hemerus is a limited liability company. The Company’s net investment in Hemerus was $773,000 and $1.2 million at June 30, 2011 and 2010, respectively.

The Company has a 16.8% ownership interest in Nephromics LLC (Nephromics). Nephromics has licensed technology related to the diagnosis of preeclampsia and has sublicensed the technology to several major diagnostic companies for the development of diagnostic assays. In fiscal 2010 and fiscal 2009, the Company received distributions of $50,000 and $1.3 million, respectively, from Nephromics. The Company accounts for its investment in Nephromics under the equity method of accounting as Nephromics is a limited liability company. Its net investment in Nephromics was $3.7 million and $4.0 million at June 30, 2011 and 2010, respectively.

The Company has a 13.6% ownership interest in ACTGen, Inc. (ACTGen), a development stage biotechnology company located in Japan. ACTGen has intellectual property related to the identification and expression of secreted molecules. The technology covers techniques to identify cellular molecules which are destined to be secreted into tissue fluids or shuttled to the cell membrane. Such molecules represent ideal targets as disease biomarkers. The Company’s net investment in ACTGen was $925,000 and $1.1 million at June 30, 2011 and 2010, respectively.

GOVERNMENT REGULATION

All manufacturers of hematology controls and calibrators are regulated under the Federal Food, Drug and Cosmetic Act, as amended. All of the Company’s hematology control products are classified as “In Vitro Diagnostic Products” by the FDA. The entire hematology control manufacturing process, from receipt of raw materials to the monitoring of control products through their expiration date, is strictly regulated and documented. FDA inspectors make periodic site inspections of the Company’s hematology control operations and facilities. Hematology control manufacturing must comply with Quality System Regulations (QSR) as set forth in the FDA’s regulations governing medical devices.

Three of the Company’s immunoassay kits, EPO, TfR and Beta2-microglobulin, have FDA clearance to be sold for clinical diagnostic use. The Company must comply with QSR for the manufacture of these kits. Biotechnology products manufactured in the United States and sold for use in the research market do not require FDA clearance.

Some of the Company’s research groups use small amounts of radioactive materials in the form of radioisotopes in their product development activities. Thus, the Company is subject to regulation and inspection by the Minnesota Department of Health and has been granted a license through August 2012. The license is renewable annually. The Company has had no difficulties in renewing this license in prior years and has no reason to believe it will not be renewed in the future. If, however, the license was not renewed, it would have minimal effect on the Company’s business since there are other technologies the research groups could use to replace the use of radioisotopes.

Both Boston Biochem and Tocris products are used as research tools and require no regulatory approval for commercialization. Some of Tocris’ products are considered controlled substances and require government permits to stock such products and to ship them to end users. The Company has no reason to believe that these annual permits will not be re-issued.

AVAILABILITY OF RAW MATERIALS

The primary raw material for the Company’s hematology controls is whole blood. Human blood is purchased from commercial blood banks while porcine and bovine blood is purchased from nearby meat processing plants. After raw blood is received, it is separated into its components, processed and stabilized. Although the cost of human blood has increased due to the requirement that it be tested for certain diseases and pathogens, the higher cost of these materials has not had a material adverse effect on the Company’s business. The Company does not perform its own pathogen testing as the supplier tests all human blood purchased. R&D Systems’ Biotechnology Division develops and manufactures the majority of its cytokines from synthetic genes developed in-house, thus significantly reducing its reliance on outside resources. R&D Systems typically has several outside sources for all critical raw materials necessary for the manufacture of products.

Tocris sources its raw material from multiple world-wide sources. Many of the starting components used in the chemical synthesis are widely available common products and no single source of raw reagents poses a supply risk to this business.

PATENTS AND TRADEMARKS

The Company owns patent protection for certain hematology controls which extend for various periods depending on the date of the patent application or patent grant. The Company is not substantially dependent on products for which it has obtained patent protection. Revenues for such products are not material to the Company’s financial results.

The Company may seek patent protection for new or existing products it manufactures. No assurance can be given that any such patent protection will be obtained. No assurance can be given that the Company’s products do not infringe upon patents or proprietary rights owned or claimed by others, particularly for genetically engineered products. The Company has not conducted a patent infringement study for each of its products. For more information on patent litigation, see Item 3 “Legal Proceedings” in this Annual Report on Form 10-K.

The Company has a number of licensing agreements with patent holders under which it has the non-exclusive right to use patented technology or the non-exclusive right to manufacture and sell certain patented proteins and related products to the research market. For fiscal 2011, 2010 and 2009, total royalties expensed under these licenses were approximately $3.4 million, $3.3 million and $3.2 million, respectively.

The Company has obtained federal trademark registration for certain of its hematology controls and biotechnology product groups which extend for various periods depending upon the date of the trademark grant. The Company believes it has common law trademark rights to certain marks in addition to those which it has registered.

SEASONALITY OF BUSINESS

Biotechnology segment products marketed by the Company historically experience a slowing of sales or of the rate of sales growth during the summer months. The Company also usually experiences a slowing of sales in both of its reportable segments during the Thanksgiving to New Year holiday period. The Company believes this seasonality is a result of vacation schedules in Europe and Japan and of academic schedules in the United States.

SIGNIFICANT CUSTOMERS

No single customer in either reportable segment accounted for more than 10% of the Company’s consolidated net sales during fiscal 2011, 2010 or 2009.

BACKLOG

There was no significant backlog of orders for the Company’s products as of the date of this Annual Report on Form 10-K or as of a comparable date for fiscal 2010. The majority of the Company’s biotechnology products are shipped within one day of receipt of the customers’ orders. The majority of hematology products are shipped based on a preset, recurring schedule.

COMPETITION

The worldwide market for protein related and chemically-based research reagents is being supplied by a number of companies, including GE Healthcare Life Sciences, BD Biosciences, Merck KGaA/EMD Chemicals, Inc., Life Technologies Corporation, Millipore Corporation, PeproTech, Inc., Santa Cruz Biotechnology, Inc., Abcam plc., Sigma-Aldrich Corporation, Thermo Fisher Scientific, Inc., Cayman Chemical Company and Enzo Biochem, Inc. The Company believes that it is one of the leading world-wide suppliers of cytokine related products in the research marketplace. The Company further believes that the expanding line of its products, their recognized quality, and the growing demand for protein related and chemically-based research reagents will allow the Company to remain competitive in the growing biotechnology research and diagnostic market.

Table of Contents

Competition is intense in the hematology control business. The first control products were developed in response to the rapid advances in electronic instrumentation used in hospital and clinical laboratories for blood cell counting. Historically, most of the instrument manufacturing companies made controls for use in their own instruments. With rapid expansion of the instrument market, however, a need for more versatile controls enabled non-instrument manufacturers to gain a foothold. Today the market is comprised of manufacturers of laboratory reagents, chemicals and coagulation products and independent control manufacturers in addition to instrument manufacturers. The principal hematology control competitors for the Company’s hematology retail products are Abbott Diagnostics, Beckman Coulter, Inc., Bio-Rad Laboratories, Inc., Streck, Inc., Siemens Healthcare Diagnostics Inc. and Sysmex Corporation. The Company believes it is the third largest supplier of hematology controls in the marketplace behind Beckman Coulter, Inc. and Streck, Inc.

EMPLOYEES

Through its subsidiaries, the Company employed 763 full-time and 71 part-time employees as of June 30, 2011, as follows:

ITEM 1A. RISK FACTORS

Statements in this Annual Report on Form 10-K, and elsewhere, that are forward-looking involve risks and uncertainties which may affect the Company’s actual results of operations. Certain of these risks and uncertainties which have affected and, in the future, could affect the Company’s actual results are discussed below. The Company undertakes no obligation to update or revise any forward-looking statements made due to new information or future events. Investors are cautioned not to place undue emphasis on these statements.

The following risk factors should be read carefully in connection with evaluation of the Company’s business and any forward-looking statements made in this Annual Report on Form 10-K and elsewhere. Any of the following risks or others discussed in this Annual Report on Form 10-K or the Company’s other SEC filings, could materially adversely affect the Company’s business, operating results and financial condition.

The Company’s future growth is dependent on the development of new products in a rapidly changing technological environment.

A major element of the Company’s growth strategy is to increase revenues through new product releases. As a result, the Company must anticipate industry trends and develop products in advance of customer needs. New product development requires planning, designing and testing at both technological and manufacturing-process levels and may require significant research and development expenditures. There can be no assurance that any products now in development, or that the Company may seek to develop in the future, will achieve feasibility or gain market acceptance. There can also be no assurance that the Company’s competitors will not succeed in developing technologies and products that are more effective than any which have been or are being developed by the Company or that would render the Company’s technologies and products obsolete or noncompetitive.

Changes in economic conditions could negatively impact the Company’s revenues and earnings.

The Company’s biotechnology products are sold primarily to research scientists at pharmaceutical and biotechnology companies and at university and government research institutions. Research and development spending by the Company’s customers and the availability of government research funding can fluctuate based on spending priorities and general economic conditions. An economic downturn or a reduction or delay in governmental funding could cause customers to delay or forego purchases of the Company’s products. The Company carries essentially no backlog of orders and changes in the level of orders received and filled daily can cause fluctuations in quarterly revenues and earnings.

The biotechnology and hematology industries are very competitive.

The Company faces significant competition across all of its product line and in each market in which it operates. Competitors include companies ranging from start-up companies, who may be able to more quickly respond to customers’ needs, to large multinational companies, which may have greater financial and marketing resources than the Company. In addition consolidation trends in the pharmaceutical and biotechnology industries have served to create fewer customer accounts and/or to concentrate purchasing decisions for some customers, resulting in increased pricing pressure on the Company. The entry into the market of manufacturers in China and other low-cost manufacturing locations is also creating increased pricing pressures, particularly in developing markets. Failure to anticipate and respond to competitors’ actions may impact the Company’s future sales and earnings.

The Company relies heavily on internal manufacturing and related operations to produce, package and distribute its products.

The Company manufactures the majority of the products it sells at its Minneapolis facility. Quality control, packaging and distribution operations support all of the Company’s sales. Any significant disruption of these operations for any reason could adversely affect sales and customer relationships, and therefore adversely affect the business. While the Company has taken certain steps to manage these operational risks, and while insurance coverage may reimburse, in whole or in part, for losses related to such disruptions, the Company’s ability to provide products in the longer term could adversely affect future sales growth and earnings.

The design and manufacture of products involves certain inherent risks. Manufacturing or design defects could lead to recalls, litigation or alerts relating to the Company’s products. A recall could result in significant costs and damage to the Company’s reputation which could reduce demand for its products.

The Company is significantly dependent on sales made through foreign subsidiaries which are subject to changes in exchange rates.

Approximately 30% of the Company’s sales are made through its foreign subsidiaries, which make their sales in foreign currencies. The Company’s revenues and earnings are, therefore, affected by fluctuations in currency exchange rates. Any adverse movement in foreign currency exchange rates could negatively affect the Company’s revenues and earnings.

The Company may be unsuccessful in integrating Boston Biochem and Tocris into its operations.

The actual financial results of Boston Biochem and Tocris could differ from the Company’s forecasts, effecting the Company’s future sales and net earnings. If the integrations of the acquired businesses are not successful, the Company may record unexpected impairment charges. Factors that will affect the success of the acquisitions include any decrease in customer loyalty caused by dissatisfaction with the combined companies’ product lines or its sales and marketing practices, including price increases, the ability to retain key employees and the ability of the Company to achieve synergies among its subsidiary companies. Such synergies include leveraging the combined companies’ sales and marketing efforts, achieving certain cost savings and effectively combining technologies to develop new products.

The Company’s success will be dependent on recruiting and retaining highly qualified personnel.

Recruiting and retaining qualified scientific, production and management personnel are critical to the Company’s success. The Company’s anticipated growth and its expected expansion into areas and activities requiring additional expertise will require the addition of new personnel and the development of additional expertise by existing personnel. The failure to attract and retain such personnel could adversely affect the Company’s business.

The Company’s business is subject to governmental laws and regulation.

The Company’s operations are subject to regulation by various U.S. federal, state and international agencies. Laws and regulations enacted and enforced by these agencies impact all aspects of the Company’s operations including design, development, manufacturing, labeling, selling and the importing and exporting of products across international borders. Any changes to laws and regulations governing such activities could have an effect on the Company’s operations. If the Company fails to comply with any of these regulations, it may become subject to fines, penalties or actions that could impact development, manufacturing and distribution and/or increase costs or reduce sales. The approval process applicable to clinical diagnostic products of the type that may be developed by the Company may take a year or more. Delays in obtaining approvals could adversely affect the marketing of new products developed by the Company, and negatively affect the Company’s revenues.

As a multinational corporation, the Company is subject to the tax laws and regulations of the U.S. federal, state and local governments and of several international jurisdictions. From time to time, new tax legislation may be implemented, which could adversely affect current or future tax filings or negatively impact the Company’s effective tax rate and thus increase future tax payments.

The Company is dependent on maintaining its intellectual property rights.

The Company’s success will depend, in part, on its ability to obtain licenses and patents, maintain trade secret protection and operate without infringing the proprietary rights of others. The Company has obtained and continues to negotiate licenses to produce a number of products claimed to be owned by others. Since the Company has not conducted a patent infringement study for each of its products, it is possible that products of the Company may unintentionally infringe patents of third parties or that the Company may have to alter its products or processes, pay licensing fees or cease certain activities because of patent rights of third parties, thereby causing additional unexpected costs and delays which may have a material adverse effect on the Company.

The Company is exposed to credit risk and fluctuations in the market values of its investment portfolio.

The Company has investments in marketable debt securities that are classified and accounted for as available-for-sale. These securities include U.S. government and agency securities, foreign government and agency securities, corporate debt securities and certificates of deposit. These investments may experience reduced liquidity due to changes in market conditions and investor demand. Although the Company has not recognized any significant losses to date on its available-for-sale securities, any significant future declines in their market values could materially adversely affect the Company’s financial condition and operating results. Given the global nature of its business, the Company has investments both domestically and internationally. Credit ratings and pricing of these investments can be negatively impacted by liquidity, credit deterioration or losses, financial results, or other factors. As a result, the value or liquidity of the Company’s available-for-sale investments could decline and result in a material impairment, which could materially adversely affect the Company’s financial condition and operating results.

The Company may incur losses as a result of its investments in other companies, the success of which is largely out of the Company’s control.

The Company’s expansion strategies include collaborations, investments in joint ventures and companies developing new products related to the Company’s business, and the acquisition of businesses for new products, technologies and additional customer base. These strategies carry risks that objectives will not be achieved and future earnings will be adversely affected.

Development stage companies of the type the Company has invested in are dependent on their ability to raise additional funds to continue research and development efforts and on receiving patent protection and/or FDA clearance to market their products. The Company uses the equity method of accounting for certain of these investments and records a percentage of the losses of these companies as losses of the Company. The Company may not have control of the expense levels of such companies and their losses may be greater than those anticipated by the Company. Additionally, if funding were unavailable or inadequate to fund operations of these companies or if patent protection or FDA clearance were not received by them, the Company may determine that its investment in one or more of these unconsolidated companies is “other than temporarily” impaired, and the Company could write off all or a portion of its investment.

ITEM 3. LEGAL PROCEEDINGS

In a previously disclosed lawsuit filed by Streck, Inc. (Streck), venued in the U.S. District Court for the District of Nebraska (the Nebraska Court), Streck alleged patent infringement involving certain patents issued to Streck relating to the addition of reticulocytes to hematology controls. Streck was seeking a royalty on sales of integrated hematology controls containing reticulocytes. The Company has reason to believe that R&D Systems, and not Streck, first invented the inventions claimed in these patents and several other patents issued to Streck. As a result, the Company requested, and in 2007 the U.S. Patent and Trademark Office (USPTO) declared, an interference to determine priority of invention between a patent application filed by R&D Systems and five Streck patents, including each of the patents involved in the lawsuit. On November 2, 2009, the interference board ordered that judgment for the Company and against Streck be entered; finding that R&D Systems was the first to invent the integrated hematology controls containing reticulocytes.

The judgment, if upheld by the Federal Circuit Court of Appeals, will constitute cancellation of all claims of the five Streck patents involving the addition of reticulocytes to hematology controls. Such cancellation may moot an earlier jury decision on October 28, 2009, at the conclusion of trial in the Nebraska Court, that the Company did not meet its burden of demonstrating by clear and convincing evidence that the Streck patents were invalid. The jury also found that a reasonable license royalty rate was 12.5%, and that R&D Systems did not willfully infringe, resulting in a judgment in favor of Streck in the amount of approximately $170,000 including court related costs. On September 30, 2010, the Nebraska Court upheld the jury verdict and, in a related action, reversed the ruling of the USPTO interference board. The Nebraska Court entered an injunction prohibiting the making and selling of the products that are the subject of the lawsuit, but stayed a portion of the injunction to allow the Company to sell inventory on-hand through December 20, 2010. In October 2010, the Company appealed the adverse decisions of the Nebraska Court to the Federal Circuit Court of Appeals. If the Company’s appeal is successful, after cancellation of the Streck patents, the Company may be issued a patent covering integrated hematology controls containing reticulocytes. The Company does not believe the resolution of the above proceedings will have a material impact on the Company’s Consolidated Financial Statements.

OVERVIEW

TECHNE Corporation and subsidiaries (the Company) are engaged in the development, manufacture and sale of biotechnology products and hematology calibrators and controls. These activities are conducted domestically through its wholly-owned subsidiaries, Research and Diagnostic Systems, Inc. (R&D Systems), Boston Biochem, Inc. (Boston Biochem), Tocris Cookson, Inc. (Tocris US), and BiosPacific, Inc. (BiosPacific). The Company’s European biotechnology operations are conducted through its wholly-owned U.K. subsidiaries, R&D Systems Europe Ltd. (R&D Europe) and Tocris Holdings Limited (Tocris UK). R&D Europe has a sales subsidiary, R&D Systems GmbH, in Germany and a sales office in France. The Company distributes its biotechnology products in China through its wholly-owned subsidiary, R&D Systems China Co., Ltd. (R&D China). R&D China has a sales subsidiary, R&D Systems Hong Kong Ltd., in Hong Kong.

On April 1, 2011, the Company acquired for approximately $7.9 million cash, the assets of Boston Biochem, Inc., a leading developer and manufacturer of innovative ubiquitin-related research products. These products provide biomedical researchers the tools that facilitate and accelerate basic research and drug discovery efforts. Boston Biochem was founded in 1997 and currently has over 800 ubiquitin-related products. The Ubiquitin Proteasome Pathway is the principal system for protein degradation and signaling in eukaryotic cells. Ubiquitination also affects proteasome-independent events such as protein localization, activity and function. These pathways are central to the regulation of almost all cellular processes. Ubiquitin and related pathways are associated with the regulation of numerous disease states including multiple cancers, diabetes, Parkinson’s, Alzheimer’s, cystic fibrosis, Angelman’s syndrome, Liddle syndrome and Wilson’s disease.

On April 28, 2011, the Company acquired for £75.0 million cash (approximately $124 million), 100% ownership of Tocris Holdings Limited and subsidiaries (Tocris), a leading supplier of reagents for non-clinical life science research. Pursuant to the purchase agreement, £7.5 million of the purchase price paid to Tocris’ shareholders is being held in escrow for 18 months to secure warranty and indemnity obligations of the shareholders. Tocris’ products are used in both in-vitro and in-vivo experiments, to understand biological processes and diseases. The business is focused on making biologically active neuro- and bio-chemicals which are used by researchers to elucidate biological processes and pathways. The products are used in life-science research activities and as part of the initial drug discovery process. Tocris is a Bristol, U.K. based company with origins deriving from Tocris Neuramin and Cookson Chemical, which were founded in 1982 and 1985, respectively. Tocris currently offers over 2,900 chemical, peptide and antibody products. The principal end users are non-clinical laboratory based researchers, working in areas such as neuroscience, cardiovascular disease, endocrinology and cellular processes. Originally a supplier of small molecules, Tocris has successfully pursued a strategy of extending its product range into related market segments such as signal transduction. The products sold by Tocris are used in various research

fields including cancer, cardiovascular disease, endocrinology, immunology, metabolic diseases, neurological diseases, pain and inflammation, and respiratory diseases. From a cellular process perspective, Tocris products are used to study angiogenesis, apoptosis, cell cycle, cell metabolism, cellular skeleton and motor proteins, extracellular matrix, adhesion molecules, signal transduction and stem cells. Tocris reagents are also used from a pharmacological perspective to study ion channels, 7-TM receptors, nuclear receptors, enzyme-linked receptors, transporter molecules and enzymes.

The Company has two reportable segments based on the nature of its products. As a result of the above acquisitions, the Company has changed the presentation of its segment disclosure from three reporting segments (biotechnology, R&D Europe and hematology) to two reporting segments (biotechnology and hematology). R&D Systems’ Biotechnology Division, R&D Europe, Tocris, R&D China, BiosPacific and Boston Biochem operating segments are included in the biotechnology reporting segment. The Company’s biotechnology reporting segment develops, manufactures and sells biotechnology research and diagnostic products world-wide. The Company’s hematology reporting segment, which consists of R&D Systems’ Hematology Division, develops and manufactures hematology controls and calibrators for sale world-wide. Corresponding items of segment information have been revised for prior periods to conform to the current year presentation.

OVERALL RESULTS

Consolidated net sales and consolidated net earnings increased 7.8% and 2.3%, respectively, for fiscal 2011 as compared to fiscal 2010. Consolidated net sales for fiscal 2011 included $4.7 million of revenues from companies acquired during fiscal 2011. Consolidated net sales and consolidated net earnings in fiscal 2011 were affected by changes in exchange rates from the prior year used to convert consolidated net sales and consolidated net earnings in foreign currencies into U.S. dollars and the impact of repatriation of prior-year earnings in fiscal 2010. The favorable impact in fiscal 2011 on consolidated net sales and consolidated net earnings of the change from the prior year in exchange rates was $466,000 and $258,000, respectively. Consolidated net earnings for fiscal 2010 included a $4.7 million tax benefit as a result of a foreign currency exchange tax loss on the repatriation of prior-year earnings from R&D Europe to the U.S.

Consolidated net sales and consolidated net earnings increased 1.9% and 4.3%, respectively, for fiscal 2010 as compared to fiscal 2009. Consolidated net sales and consolidated net earnings in fiscal 2010 were slightly affected by changes in exchange rates from the prior year used to convert consolidated net sales and consolidated net earnings in foreign currencies into U.S. dollars. The favorable impact in fiscal 2010 on consolidated net sales and consolidated net earnings of the change from the prior year in exchange rates was $888,000 and $68,000, respectively. Consolidated net earnings for fiscal 2010 included a $4.7 million tax benefit as a result of a foreign currency exchange tax loss on the repatriation of prior-year earnings from R&D Europe to the U.S.

RESULTS OF OPERATIONS

Net sales

Net sales (in thousands):

Consolidated net sales for fiscal 2011 were $290.0 million, an increase of $20.9 million (7.8%) from fiscal 2010. Consolidated net sales for fiscal 2011 included $4.7 million of revenue from companies acquired during fiscal 2011 and were favorably affected by the change from the prior year in exchange rates used to convert sales in foreign currencies into U.S. dollars. Excluding the acquisitions and the effect of changes in foreign currency exchange rates, consolidated net sales increased 5.9% in fiscal 2011 from fiscal 2010.

Biotechnology segment net sales increased $19.6 million (7.8%) in fiscal 2011 from fiscal 2010. Included in biotechnology net sales were $4.7 million of sales by Boston Biochem and Tocris, which were acquired by the Company during fiscal 2011, and $2.5 million of sales of new protein based biotechnology products which had their first sale in fiscal 2011. The majority of the biotechnology net sales increase, exclusive of acquisitions, was from

increased sales volume. Biotechnology net sales to U.S. industrial pharmaceutical and biotechnology customers, biotechnology’s largest customer group, increased 4.8% in fiscal 2011 compared to the prior fiscal year. Biotechnology net sales to U.S. academic customers and Pacific Rim distributors increased 6.4% and 4.1%, respectively, in fiscal 2011 from fiscal 2010. Biotechnology sales by R&D China and R&D Europe increased 26.0% (22.6% in constant currency) and 4.4% (4.1% in constant currency) in fiscal 2011 from fiscal 2010, respectively. Hematology segment net sales in fiscal 2011 increased $1.3 million (7.0%) mainly due to increased sales volume.

Consolidated net sales for fiscal 2010 were $269.0 million, an increase of $5.1 million (1.9%) from fiscal 2009. Consolidated net sales were favorably affected by the change from the prior year in exchange rates used to convert sales in foreign currencies into U.S. dollars. Excluding the effect of changes in foreign currency exchange rates, consolidated net sales increased 1.6% in fiscal 2010 from fiscal 2009.

Biotechnology segment net sales in fiscal 2010 increased $4.2 million (1.7%) from fiscal 2009. The majority of the biotechnology net sales increase was from increased sales volume. Included in consolidated net sales in fiscal 2010 were $2.8 million of sales of new protein based biotechnology products, which had their first sale in fiscal 2010. Biotechnology net sales to U.S. academic customers, Pacific Rim distributors and sales by R&D China increased 4.0%, 10.5% and 21.8%, respectively, in fiscal 2010 from fiscal 2009. Biotechnology net sales to U.S. industrial pharmaceutical and biotechnology customers were flat in fiscal 2010 compared to the prior fiscal year. R&D Europe net sales increased 0.3% in fiscal 2010. R&D Europe net sales decreased slightly (0.9%) for fiscal 2010 when measured at currency rates in effect in fiscal 2009. Hematology net sales in fiscal 2010 increased $892,000 (5.1%) mainly due to increased sales volume.

Gross margins

Gross margins, as a percentage of net sales, were as follows:

The consolidated gross margin for fiscal 2011 was negatively impacted 0.7% as a result of purchase accounting related to inventory and intangible assets from the Boston Biochem and Tocris acquisitions. Under purchase accounting, inventory acquired is valued at fair market value less expected selling and marketing costs, resulting in reduced margins in future periods as the inventory is sold. At the acquisition dates, the value of acquired inventory was increased $25.7 million. Approximately $1.8 million of which was included in cost of sales in fiscal 2011. In addition, under purchase accounting, intangible assets related to technology acquired are amortized to cost of sales over their estimated useful life. Technology acquired as of the acquisition dates was $27.2 million. Approximately $455,000 of which was amortized to cost of sales in fiscal 2011. The improvement in consolidated gross margins for fiscal 2010 was mainly the result of incremental profit on increased sales volume in the biotechnology segment.

Selling, general and administrative expenses

Selling, general and administrative expenses increased $3.2 million (9.8%) and decreased $989,000 (3.0%) in fiscal 2011 and 2010, respectively. Selling, general and administrative expenses were as follows (in thousands):

18

Table of Contents

The change from the comparable fiscal year was primarily the result of the following (in thousands):

The decrease in non-acquisition related legal fees in fiscal 2011 and 2010 was primarily from lower costs associated with ongoing patent interference and infringement litigation. The increase in fiscal 2011 and decrease in fiscal 2010 in profit sharing and bonus expense reflect the change in financial results from each of the respective prior years. The remainder of the change in selling, general and administrative expenses for both fiscal years was mainly the result of annual wage, salary and benefit increases, partially offset by a decrease in stock-based compensation expense in fiscal 2010.

Research and development expenses

Research and development expenses increased $864,000 (3.4%) and $1.6 million (6.6%) in fiscal 2011 and 2010, respectively, as compared to prior-year periods. The increases were primarily the result of the development of new proteins, antibodies and assay kits by R&D Systems’ Biotechnology Division. The Company introduced 1,646 and 1,482 new biotechnology products in fiscal 2011 and 2010, respectively. Research and development expenses are composed of the following (in thousands):

Amortization of intangible assets

Total amortization expense was $1.5 million, $960,000 and $960,000 in fiscal 2011, 2010 and 2009, respectively, related mainly to technologies, trade names and customer relationships acquired as a result of acquisitions in fiscal 2006 and fiscal 2011. Amortization expense related to technologies included in cost of sales was $890,000, $435,000 and $435,000 in fiscal 2011, 2010 and 2009, respectively. Amortization expense related to trade names, customer relationships and a non-compete agreement included in selling, general and administrative expense was $575,000, $525,000 and $525,000 in fiscal 2011, 2010 and 2009, respectively. Intangible assets are being amortized over lives of 5 to 15 years.

Interest income

Interest income for fiscal 2011, 2010 and 2009 was $3.8 million, $4.4 million and $7.6 million, respectively. The decrease in both fiscal 2011 and 2010 from the prior fiscal year was primarily the result of lower rates of return on cash and available-for-sale investments, offset in part by higher cash and available-for-sale investment balances prior to the acquisitions in late fiscal 2011.

Table of Contents

Other non-operating expense, net

Other non-operating expense, net, consists of foreign currency transaction gains and losses, rental income, building expenses related to rental property and the Company’s share of losses by equity method investees as follows (in thousands):

Income taxes

Income taxes for fiscal 2011, 2010 and 2009 were provided at rates of approximately 31.9%, 29.8% and 32.3%, respectively, of consolidated earnings before income taxes. The fiscal 2011 consolidated tax rate was positively impacted by the renewal of the U.S. research and development credit and included $431,000 of credit for the January to June 2010 period. The fiscal 2010 consolidated tax rate was positively impacted by a $4.7 million tax benefit from a foreign currency exchange tax loss related to the repatriation of £50 million ($74.4 million) from R&D Europe to the U.S. The Company had previously paid U.S. income taxes on the foreign earnings that were included in the repatriated funds. Excluding this tax benefit, the effective tax rate for fiscal 2010 would have been 32.8%. This is slightly higher than the fiscal 2009 effective tax rate primarily as a result of the expiration of the U.S. research and development credit at the end of the second quarter of fiscal 2010. The fiscal 2009 consolidated tax rate was positively impacted by the renewal of the U.S. research and development credit. The fiscal 2009 credit included $354,000 of credit for the January to June 2008 period. U.S. federal taxes have been reduced by the manufacturer’s deduction provided for under the American Jobs Creation Act of 2004. Foreign income taxes have been provided at rates which approximate the tax rates in the countries in which R&D Europe and R&D China operate. The Company expects income tax rates for fiscal 2012 to range from 31% to 33%.

LIQUIDITY AND CAPITAL RESOURCES

Cash, cash equivalents and available-for-sale investments at June 30, 2011 were $273 million compared to $310 million at June 30, 2010. The Company has an unsecured line of credit of $750,000 available at June 30, 2011 which expires on October 31, 2011. The interest rate charged on the line of credit is a floating rate at the one month London interbank offered rate (Libor) plus 1.75%. There were no borrowings on the line in the current or prior fiscal year.

At June 30, 2011, approximately 82%, 15%, and 3% of the Company’s cash and equivalent account balances of $77.6 million are located in the U.S., United Kingdom and China, respectively. At June 30, 2011, approximately 96% of the Company’s available-for-sale investment accounts are located in the U.S., with the remaining 4% in China. Management of the Company expects to be able to meet its foreseeable future cash and working capital requirements for operations, facility expansion and capital additions at each of its geographical locations through currently available funds, cash generated from operations and maturities of available-for-sale investments.

Cash flows from operating activities

The Company generated cash from operations of $127 million, $111 million and $111 million in fiscal 2011, 2010 and 2009, respectively. The cash generated from operating activities in fiscal 2011 as compared to fiscal 2010 was mainly the result of changes in income taxes payable and deferred income taxes as a result of timing of tax payments and the usage in fiscal 2011 of the foreign tax credit carryforward generated in fiscal 2010 plus increased net earnings of $2.5 million.

The cash generated from operating activities in fiscal 2010 as compared to fiscal 2009 was mainly the result of changes in operating assets and liabilities offset by increased net earnings of $4.5 million. In fiscal 2010 changes in operating assets and liabilities negatively impacted net cash from operating activities by $7.8 million compared to a $4.1 million negative impact in fiscal 2009.

Cash flows from investing activities

On April 1, 2011, the Company acquired the assets of Boston Biochem, a leading developer and manufacturer of innovative ubiquitin-related biotechnology research products, for approximately $7.9 million. On April 28, 2011, the Company acquired 100% ownership of Tocris, a leading supplier of reagents for non-clinical life science research for £75 million (approximately $124 million). The acquisitions were financed through cash and cash equivalents on hand and sales of available-for-sale investments.

The Company’s net (sales) purchases of available-for-sale investments in fiscal 2011, 2010 and 2009 were ($22.2) million, $110 million and ($26.5) million, respectively. The large net purchase of available-for-sale investments in fiscal 2010 was primarily the result of the repatriation of funds from the U.K., where the funds had been invested in instruments classified as cash and equivalents, to the U.S., where the funds were invested in available-for-sale investments. The Company’s investment policy is to place excess cash in municipal and corporate bonds with the objective of obtaining the highest possible return while minimizing risk and keeping the funds accessible.

Capital additions consist of the following (in thousands):

Table of Contents

Included in fiscal 2011, 2010 and 2009 capital additions were approximately $528,000, $2.7 million and $1.8 million, respectively, related to the construction and renovation of laboratory space at the Company’s Minneapolis facility. Fiscal 2011 also included a $420,000 construction expenditure related to a new tenant in Minneapolis and $77,000 of smaller renovation projects at R&D Europe and R&D China. In fiscal 2009, the Company purchased two parking lots adjacent to its Minneapolis facility for $2.2 million. The property purchase was financed through available cash.

OFF-BALANCE SHEET ARRANGEMENTS

The Company is not a party to any off-balance sheet transactions, arrangements or obligations that have, or are reasonably likely to have, a current or future material effect on the Company’s financial condition, changes in the financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

CRITICAL ACCOUNTING POLICIES

Management’s discussion and analysis of the Company’s financial condition and results of operations are based upon the Company’s Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The Company has identified the policies outlined below as critical to its business operations and an understanding of results of operations. The listing is not intended to be a comprehensive list of all accounting policies.

Valuation of available-for-sale investments

The Company considers all of its marketable securities available-for-sale and reports them at fair market value. Fair market values are based on quoted market prices. Unrealized gains and losses on available-for-sale investments are excluded from income, but are included, net of taxes, in other comprehensive income. If an “other-than-temporary” impairment is determined to exist, the difference between the value of the investment recorded in the financial statements and the Company’s current estimate of fair value is recognized as a charge to earnings in the period in which the impairment is determined. Net unrealized gains on available-for-sale investments at June 30, 2011 were $1.0 million.

Valuation of inventory

Inventories are stated at the lower of cost (first-in, first-out method) or market. The Company regularly reviews inventory on hand for slow-moving and obsolete inventory, inventory not meeting quality control standards and inventory subject to expiration.

To meet strict customer quality standards, the Company has established a highly controlled manufacturing process for proteins and antibodies. New protein and antibody products require the initial manufacture of multiple batches to determine if quality standards can be consistently met. In addition, the Company will produce larger batches of established products than current sales requirements due to economies of scale. The manufacturing process for proteins and antibodies, therefore, has and will continue to produce quantities in excess of forecasted usage. The Company values its manufactured protein and antibody inventory based on a two-year forecast. The establishment of a two-year forecast requires considerable judgment. Protein and antibody quantities in excess of the two-year usage forecast are not valued due to uncertainty over salability. The value of protein and antibody inventory not valued at June 30, 2011 was $21.8 million.

The fair value of inventory purchased in fiscal 2011 through the acquisitions of Boston Biochem and Tocris were determined based on quantities acquired, selling prices at the date of acquisition and management’s assumptions regarding inventory having future value and the costs to sell such inventories. At the acquisition dates, the value of acquired inventory was increased $25.7 million for a total acquired inventory value of $33.0 million. In addition, the Company acquired inventory that was not valued as part of the purchase price allocation as it was in excess of forecasted usage. The increase in value of the acquired inventory remaining at June 30, 2011 was $23.9 million.

Valuation of intangible assets and goodwill

When a business is acquired, the purchase price is allocated, as applicable, between tangible assets, identifiable intangible assets and goodwill. Determining the portion of the purchase price allocated to intangible assets requires significant estimates. The fair value of intangible assets acquired in fiscal 2011, including developed technologies, trade names, customer relationships and a non-compete agreement, were based on management’s forecasted cash inflows and outflows using a relief-from-royalty and multi-period excess earnings method with consideration to other factors including an independent valuation of management’s assumptions. Intangible assets are being amortized over their estimated useful lives, ranging from 5 to 15 years. The Company reviews the carrying amount of intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Intangible assets, net of accumulated amortization, were $52.3 million at June 30, 2011.

Goodwill recognized in connection with a business acquisition represents the excess of the aggregate purchase price over the fair value of net assets acquired. Goodwill is tested for impairment annually or more frequently if changes in circumstance or the occurrence of events suggest impairment exists. Assessing the impairment of goodwill requires the Company to make judgments regarding the fair value of the net assets of its reporting units and the allocation of the carrying amount of shared assets to the reporting units. The Company’s annual assessment included comparison of the carrying amount of the net assets of a reporting unit, including goodwill, to the fair value of the reporting unit. A significant change in the Company’s market capitalization or in the carrying amount of net assets of a reporting unit could result in an impairment charge in future periods. The Company completed its annual impairment testing of goodwill and concluded that no impairment existed as of June 30, 2011, as the fair values of the Company’s reporting units substantially exceeded their carrying values, with the exception of the Tocris and Boston Biochem reporting units which were acquired in the fourth quarter of fiscal 2011. The carrying values of Tocris and Boston Biochem approximate fair values at June 30, 2011. Goodwill at June 30, 2011 was $86.6 million.

Valuation of investments

The Company has made equity investments in several start-up and early development stage companies, among them ChemoCentryx, Inc. (CCX), Nephromics, Hemerus Medical LLC (Hemerus), and ACTGen, Inc (ACTGen). The accounting treatment of each investment (cost method or equity method) is dependent upon a number of factors, including, but not limited to, the Company’s share in the equity of the investee and the Company’s ability to exercise significant influence over the operating and financial policies of the investee. In determining which accounting treatment to apply, the Company must make judgments based upon the quantitative and qualitative aspects of the investment.

The Company periodically assesses its equity investments for impairment. Development stage companies of the type the Company has invested in are dependent on their ability to raise additional funds to continue research and development efforts and on receiving patent protection and/or U.S. Food and Drug Administration (FDA) clearance to market their products. If such funding were unavailable or inadequate to fund operations or if patent protection or FDA clearance were not received, the Company would potentially recognize an impairment loss to the extent of its remaining net investment. The Company’s net investments at June 30, 2011 in CCX, Nephromics, Hemerus and ACTGen were $14.3 million, $3.7 million, $773,000 and $925,000, respectively.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the FASB issued Accounting Standards Update (ASU) No. 2011-05 Comprehensive Income under an amendment to Topic 220. Under this update, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU No. 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The update does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The Company must comply with ASU No. 2011-05 for the quarter ended September 30, 2012. The Company does not believe this update will have a material impact on the Company’s consolidated financial statements.

In June 2009, the FASB issued Statement of Financial Accounting Standard No. 167, now codified in ASC Topic 810, Consolidation. This Statement amends the consolidation guidance applicable to variable interest entities and was effective for the Company beginning July 1, 2010. The adoption of the Statement did not have a material impact on the Company’s Consolidated Financial Statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES

ABOUT MARKET RISK

At the end of fiscal 2011, the Company had a portfolio of fixed income securities, excluding those classified as cash and cash equivalents, of $195 million (see Note C to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K). These securities, like all fixed income instruments, are subject to interest rate risk and will decline in value if market interest rates increase. The Company’s investment policy requires all investment in short-term and long-term securities to have at least debt ratings of A1 or A3 (or the equivalent), respectively. As the Company’s fixed income securities are classified as available-for-sale, no gains or losses are recognized by the Company in its Consolidated Statement of Earnings due to changes in interest rates unless such securities are sold prior to maturity. The Company generally holds its fixed income securities until maturity and, historically, has not recorded any material gains or losses on any sale prior to maturity.

The Company operates internationally, and thus is subject to potentially adverse movements in foreign currency rates. Approximately 30% of consolidated net sales are made in foreign currencies, including 15% in euro, 7% in British pound sterling, 3% in Chinese yuan and the remaining 5% in other European currencies. As a result, the Company is exposed to market risk mainly from foreign exchange rate fluctuations of the euro, British pound sterling, and the Chinese yuan as compared to the U.S. dollar as the financial position and operating results of the Company’s foreign operations are translated into U.S. dollars for consolidation.

Month-end exchange rates between the British pound sterling, euro and Chinese yuan and the U.S. dollar, which have not been weighted for actual sales volume in the applicable months in the periods, were as follows:

The Company’s exposure to foreign exchange rate fluctuations also arises from trade receivables and intercompany payables denominated in one currency in the financial statements, but receivable or payable in another currency. At June 30, 2011, the Company had the following trade receivable and intercompany payables denominated in one currency but receivable or payable in another currency (in thousands):

All of the above balances are revolving in nature and are not deemed to be long-term balances.

The Company does not enter into foreign currency forward contracts to reduce its exposure to foreign currency rate changes on forecasted intercompany sales transactions or on intercompany foreign currency denominated balance sheet positions. Foreign currency transaction gains and losses are included in “Other non-operating expense, net” in the Consolidated Statement of Earnings. The effect of translating net assets of foreign subsidiaries into U.S. dollars are recorded on the Consolidated Balance Sheet as part of “Accumulated other comprehensive (loss) income.”

The effects of a hypothetical simultaneous 10% appreciation in the U.S. dollar from June 30, 2011 levels against the euro, British pound sterling and Chinese yuan are as follows (in thousands):
