TABLE OF CONTENTS

PART I

Item 1. Business.

Overview

MISONIX, INC. ("Misonix" or the "Company") is a New York corporation which, through its predecessors, was first organized in 1959. The Company designs, manufactures, develops and markets minimally invasive ultrasonic surgical device products. These products include the BoneScalpelTM cutting system("BoneScalpel") which is used among other things for surgical procedures of the spine and on maxillofacial procedures, the SonaStar® Surgical Aspirator ("SonaStar") which is used to emulsify and remove soft and hard tumors, the SonicOne® Wound Cleansing and Debridement System ("SonicOne") that offers tissue specific debridement and cleansing of wounds for effective removal of devitalized tissue and fibrin deposits while sparing viable cells, and the AutoSonix ultrasound cutting and coagulating system ("AutoSonix") which is distributed and marketed for Misonix through an agreement with Covidien Ltd. Misonix also markets its Lysonix ultrasound assisted liposuction device ("Lysonix") through Mentor Corporation, a subsidiary of Johnson & Johnson ("Mentor").

The Company's 100% owned subsidiary, Hearing Innovations, Inc. ("Hearing Innovations"), is a development company with patented HiSonic ultrasonic technology for the treatment of profound deafness and tinnitus.

In fiscal 2012, approximately 41% of the Company's net sales were to foreign markets. These sales had credit risks as some large distributor sales were not secured by letters of credit, but given credit terms, after analysis on open account. Some open account sales require a 50% down payment which generally covers the cost of the equipment. Foreign country sales on open credit terms do not exceed sixty days. Distributors that are not given credit terms either pay in advance or have letters of credit securing the sales. All foreign sales are remitted to Misonix in U.S. currency.

Discontinued Operations

Laboratory and Forensic Safety Products Business

On October 19, 2011, Misonix sold its Laboratory and Forensic Safety Products business, which comprised substantially all of the Laboratory and Scientific products segment, to Mystaire, Inc. ("Mystaire") for $1.5 million in cash plus a potential additional payment of up to an aggregate $500,000 based upon 30% of net sales in excess of $2.0 million for each of the three years following the closing (the "earn-out"). The Laboratory and Forensic Safety Products business manufactured and marketed ductless fume, laminar airflow and polymerase chain reaction workstations both domestically and internationally with revenues for fiscal 2011 of approximately $2.1 million.

In accordance with the Asset Purchase Agreement with Mystaire, Misonix retained among other items, the existing accounts receivable, inventory, accounts payable and accrued expenses of the Laboratory and Forensic Safety Products business. After considering the proceeds received of $1,500,000 in cash, professional fees of $25,000 in connection with the sale and the net book value of the assets sold of $24,000, which was comprised primarily of property and equipment, Misonix reported a gain on sale of $1,451,000 and recorded income taxes of $242,000 on the gain during the fiscal year ended June 30, 2012. The earn-out will not be factored into the gain on sale until it is earned by Misonix.

In accordance with the terms of the Transition and Manufacturing Services Agreement with Mystaire, which was entered into as part of the sale, Misonix continued for a period of six weeks to manufacture and deliver products for orders received prior to the closing date as well as to provide product to Mystaire as transition inventory, which transition period was completed on November 30, 2011.

The results of operations of the Laboratory and Forensic Safety Products business will be presented as discontinued operations for all periods presented as Misonix does not have any significant cash flow or continuing involvement in this business. Following the sale of the Laboratory and Forensic Safety Products business, the Company operates in one reportable segment, Medical Devices.

Labcaire Systems

On August 4, 2009, the Company sold its Labcaire Systems, Ltd. ("Labcaire") subsidiary to PuriCore International Limited ("PuriCore Limited") for a total purchase price of up to $5.6 million. The Company received $3.6 million at closing and a promissory note in the principal amount of $1 million, payable in equal installments of $250,000 on the next four anniversaries of the closing. During the year ended June 30, 2011, the Company received the first installment. The note receivable was discounted over the four years using a 4% imputed interest rate. This rate was consistent with published discounts. The discounted value of the note ($900,000) was used to determine gain or loss on the sale and the remaining outstanding balance is included in other assets in the consolidated balance sheet, with the current portion reflected as a component of notes receivable. The Company was also to receive a commission paid on sales for the period commencing on the date of closing and ending on December 31, 2013 of 8% of the pass through Automated Endoscope Reprocessing ("AER") and Drying Cabinet products, and 5% of license fees from any chemical licenses marketed by Labcaire directly associated with sale of AERs, specifically for the disinfection of the endoscope. The aggregate commission payable to the Company was also to be subject to a maximum payment of $1 million. The aggregate commission was not recognized in determining the gain or loss on the sale of Labcaire until the commission was to be paid. As of June 30, 2011, there were no commissions paid. For the year ended June 30, 2010, the Company recorded a pre-tax loss on the sale of Labcaire of $295,879. Results of Labcaire operations have been reported as a discontinued operation for all periods presented.

In January 2011, PuriCore Limited initiated a lawsuit against the Company in the High Court of Justice, Queens Bench Division, Commercial Court, Royal Courts of Justice, London, England (Claim No. 2011-42) (the "Lawsuit"). In the Lawsuit, PuriCore Limited claimed damages from the Company in respect of breach of warranties contained in the Stock Purchase Agreement, dated August 4, 2009 (the "SPA"), pursuant to which the Company sold Labcaire to PuriCore Limited. PuriCore Limited claimed damages of £2,167,000 or approximately $3,600,000, plus interest and its legal costs. The Company denied the allegations contained in the Lawsuit.

On July 19, 2011, PuriCore Limited and the Company reached an agreement to settle the Lawsuit (the "Settlement"). The Settlement provides that the Company (i) forgive in full PuriCore Limited and PuriCore plc's obligation under the SPA to pay up to $1 million of the previously unrecorded, contingent commissions (as described above); (ii) pay PuriCore, Inc. ("PuriCore"), an affiliate of PuriCore Limited, $650,000 towards PuriCore Limited's legal costs which had been accrued for as of June 30, 2011 and recorded as a component of loss from discontinued operations for the year ended June 30, 2011 and (iii) enter into a Product License and Distribution Agreement, dated as of July 19, 2011, with PuriCore (the "Distribution Agreement").

Pursuant to the Distribution Agreement, the Company has been granted the right to distribute PuriCore's Vashe ® solution products in the United States, on a private label basis, as an antibacterial, microbial irrigating solution for the treatment of human wound care in conjunction with therapeutic ultrasonic procedures (the "Field"). PuriCore has agreed, subject to modification, not to sell the products that are the subject of the Distribution Agreement (the "Licensed Products") to any other therapeutic ultrasound company for distribution in the Field in the United States ("Exclusivity"). The Company has agreed not to sell or distribute in the United States in the Field any irrigating solution that has anti-microbial properties otherthan the Licensed Products so long as the Company has Exclusivity.

The Distribution Agreement is for a three (3) year term with automatic renewals for successive two (2) year periods; provided that the Company and PuriCore have agreed upon sales volume targets for each renewal period (such volume targets not to increase by more than ten (10%) percent year over year unless otherwise agreed) and provided that the cost terms shall be no less favorable than the twelve (12) months leading up to the start of such renewal period. In no event will the Distribution Agreement survive beyond the expiration or invalidation of all of PuriCore's patents.

During the initial three year term of the Distribution Agreement, the Company is obligated to either purchase or pay a minimum of $2 million in gross margin value to PuriCore for the Licensed Products (the "Minimum Payment"). The Minimum Payment is subject to downward adjustment and elimination in the event that (i) PuriCore chooses to eliminate Exclusivity, (ii) the Company's right to manufacture the Licensed Products under certain conditions has been triggered but the Company is unable to manufacture the Licensed Products or to have the Licensed Products manufactured for it by third parties or (iii) the U.S. Food and Drug Administration ("FDA") has made a final determination that prohibits the sale of the licensed products for use in the Field. As of June 30, 2012, Misonix has incurred approximately $321,750 towards the Minimum Payment, leaving a Minimum Payment balance of $1,678,250. At the start of fiscal 2012, the discounted value of the note was $650,000. During fiscal 2012, Misonix has purchased $451,883 of Licensed Products from Puricore, which has been offset against the note, leaving a note receivable balance of $298,117.

The Company has the right to manufacture the Licensed Products if PuriCore is unable to meet certain performance standards and will pay PuriCore a royalty after the $2 million in gross margin value requirement has been satisfied if the Company is then manufacturing the Licensed Products.

During a renewal period, PuriCore may terminate the Distribution Agreement (i) if the Company fails to purchase the agreed upon volume target for such renewal period and does not cure such failure in accordance with the Distribution Agreement or (ii) upon twelve (12) months' notice.

High Intensity Focused Ultrasound Technology

In consideration for the sale of its rights to the High Intensity Focused Ultrasound ("HIFU") technology to USHIFU, LLC ("USHIFU") in May 2010, Misonix will receive up to approximately $5.8 million, paid out of an earn-out of 7% of gross revenues received by USHIFU related to the business being sold up to the time the Company has received the first $3 million and thereafter 5% of the gross revenues up to the $5.8 million. Commencing 90 days after each December 31 st and beginning December 31, 2011, the payments will be the greater of (a) $250,000 or (b) 7% of gross revenues received up to the time the Company has received the first $3 million and thereafter 5% of gross revenues up to the $5.8 million.During the three months ended June 30, 2012, the Company received $254,788 related to an earn-out from the sale, which has been recorded as a component of gain on the sale of discontinued operations during the period.

Medical Devices

On June 1, 2011, Misonix entered a new five-year exclusive U.S. distribution agreement with Anika Therapeutics S.r.l., a wholly owned subsidiary of Anika Therapeutics, Inc. (NASDAQ: ANIK), a leader in products for tissue protection, healing, and repair. Misonix will sell and distribute Anika's Hyalomatrix® product, a skin substitute based on hyaluronic acid technology. Hyalomatrix is indicated for treatment of a wide range of acute and chronic wounds and will be a companion product for the SonicOne.

Anika will manufacture and supply finished product to Misonix, while Misonix will be responsible for all aspects of commercialization in the United States. A recognized leader in advanced ultrasonic wound management, Misonix has U.S. sales and marketing organizations for both the surgery and clinic settings, where acute and chronic wounds are treated.

On July 19, 2011, Misonix and PuriCore entered into the Distribution Agreement whereby Misonix will distribute, on a limited exclusive basis with respect to other therapeutic ultrasound companies in the United States, a private label version of PuriCore's Vashe wound therapy product trademarked as SOMA, which is a solution intended for cleansing, irrigating, moistening, and debriding acute and chronic dermal lesions. Use of the new product will be emphasized in conjunction with clinical procedures performed with Misonix ultrasonic systems and gives surgeons and clinicians an expanding line of products for treating wounds. The Distribution Agreement is for three years with a two year extension contingent on meeting certain goals. As part of this Distribution Agreement, Misonix has the obligation over a three year period to either purchase or pay a minimum of $2 million in gross margin value to PuriCore. See "Discontinued Operations – Labcaire Systems" .

In October 1996, the Company entered into a twenty-year license agreement (the "Covidien License") with Covidien Ltd. The Covidien License covers the further development of the Company's medical technology relating to ultrasonic cutting, which uses high frequency sound waves to coagulate and divide tissue for both open and laparoscopic surgery. The Covidien License gives Covidien exclusive worldwide marketing and sales rights for this technology and device. Total sales of this device were approximately $1,484,000 and $3,260,000 for the fiscal years ended June 30, 2012 and 2011, respectively. Total royalties from sales of this device were approximately $488,000 and $550,000 for the fiscal years ended June 30, 2012 and 2011, respectively.

The Company is currently negotiating a new distribution agreement with Mentor for the sale, marketing and distribution of the Lysonix soft tissue aspirator used for cosmetic surgery. Total sales of this device were approximately $1,492,000 and $900,000 for the fiscal years ended June 30, 2012 and 2011, respectively.

Market and Customers

The Company relies on its licensee, Covidien, for marketing the AutoSonix product. The Company relies on Mentor, Aesculap, Inc. ("Aesculap"), independent sales agents, and other regional distributors for marketing the SonaStar and BoneScalpel, and the Lysonix products, exclusively in the United States. The Company sells its SonicOne Wound Cleansing and Debridement System for certain other applications through direct sales persons and sales agents throughout the United States. All products are sold through distributors or representatives outside the United States.

In September 2007, the Company completed an agreement with Mentor for domestic sales of its ultrasound assisted liposuction product, the Lysonix. Mentor agreed to minimum purchase order provisions for the Lysonix for a one year term commencing September 30, 2007, and successive annual renewals upon mutual agreement by the companies. The agreement with Mentor for the Lysonix in the United States is in the process of being negotiated for renewal.

Manufacturing and Supply

The Company manufactures and assembles its medical device products at its production facility located in Farmingdale, New York. The Company's products include components manufactured by other companies in the United States. The Company is not dependent upon any single source of supply and has no long-term supply agreements. The Company believes that it will not encounter difficulty in obtaining materials, supplies and components adequate for its anticipated short-term needs.

Competition

Competition in the medical device products industry is rigorous with many companies having significant capital resources, large research laboratories and extensive distribution systems in excess of the Company's. Some of the Company's major competitors are Johnson & Johnson, Valley Lab, a division of Tyco Healthcare, Integra Life Sciences, Inc., Sööring, and Stryker.

Regulatory Requirements

The Company's medical device products are subject to the regulatory requirements of the FDA. A medical device as defined by the FDA is an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component, part, or accessory which is recognized in the official National Formulary or the United States Pharmacopoeia, or any supplement to such listings, intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or animals, or intended to affect the structure or any function of the body of man or animals, and which does not achieve any of its primary intended purposes through chemical action within or on the body of man or animals and which is not dependent upon being metabolized for the achievement of any of its primary intended purposes (a "medical device"). The Company's products that are subject to FDA regulations for product labeling and promotion comply with all applicable regulations. The Company is listed with the FDA as a medical device manufacturer and has the appropriate FDA Establishment Numbers in place. The Company has a post-market monitoring system in place such as Complaint Handling and Medical Device Reporting procedures. All current devices manufactured and sold by the Company have all the necessary regulatory approvals. The Company is not aware of any situations which would be materially adverse at this time and neither has the FDA sought legal remedies available, nor have there been any violations of its regulations alleged, against the Company at present.

Item 1A. Risk Factors.

In addition to the other information contained in this Annual Report on Form 10-K and the exhibits hereto, the following risk factors should be considered carefully in evaluating our business. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This section contains forward-looking statements. You should refer to the explanation of the qualifications and limitations on forward-looking statements set forth immediately prior to the beginning of Item 1 of this Annual Report on Form 10-K. Additional risks not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition or results of operations. The following list sets forth many, but not all, of the factors that could impact upon the Company's ability to achieve results discussed in any forward leading statement. Investors should understand that it is not possible to predict or identify all such factors and should not consider this list to be a complete statement of all potential risks and uncertainties .

Risks Related to Our Business

We are subject to extensive medical device regulation which may impede or hinder the approval process for our products and, in some cases, may not ultimately result in approval or may result in the recall or seizure of previously approved products.

Our products, development activities and manufacturing processes are subject to extensive and rigorous regulation by the FDA pursuant to the Federal Food, Drug, and Cosmetic Act (the "FDC Act"), by comparable agencies in foreign countries, and by other regulatory agencies and governing bodies. Under the FDC Act, medical devices must receive FDA clearance or approval before they can be commercially marketed in the U.S. In addition, most major markets for medical devices outside the U.S. require clearance, approval or compliance with certain standards before a product can be commercially marketed. The process of obtaining marketing approval or clearance from the FDA for new products, or with respect to enhancements or modifications to existing products, could:

Even after products have received marketing approval or clearance, product approvals and clearances by the FDA can be withdrawn due to failure to comply with regulatory standards or the occurrence of unforeseen problems following initial approval. There can be no assurance that we will receive the required clearances from the FDA for new products or modifications to existing products on a timely basis or that any FDA approval will not be subsequently withdrawn. Later discovery of previously unknown problems with a product or manufacturer could result in fines, delays or suspensions of regulatory clearances, seizures or recalls of products, operating restrictions and/or criminal prosecution. The failure to receive product approval clearance on a timely basis, suspensions of regulatory clearances, seizures or recalls of products or the withdrawal of product approval by the FDA could have a material adverse effect on our business, financial condition or results of operations.

We may not meet regulatory quality standards applicable to our manufacturing and quality processes.

As a medical device manufacturer, we are required to register with the FDA and are subject to periodic inspection by the FDA for compliance with the FDA's Quality System Regulation requirements, which require manufacturers of medical devices to adhere to certain regulations, including testing, quality control and documentation procedures. In addition, the Federal Medical Device Reporting regulations require us to provide information to the FDA whenever there is evidence that reasonably suggests that a medical device may have caused or contributed to a death or serious injury or, if a malfunction were to occur, could cause or contribute to a death or serious injury. Compliance with applicable regulatory requirements is subject to continual review and is rigorously monitored through periodic inspections by the FDA. In the European Community, we are required to maintain certain ISO certifications in order to sell our products and must undergo periodic inspections by notified bodies to obtain and maintain these certifications. Failure to meet regulatory quality standards could have a material adverse effect on our business, financial condition or results of operations.

Future intellectual property litigation could be costly and disruptive to us.

We operate in an industry that is susceptible to significant intellectual property litigation and, in recent years, it has been common for companies in the medical device field to aggressively challenge the patent rights of other companies in order to prevent the marketing of new devices. Intellectual property litigation is expensive, complex and lengthy and its outcome is difficult to predict. Future patent litigation may result in significant royalty or other payments or injunctions that can prevent the sale of products and may significantly divert the attention of our technical and management personnel. In the event that our right to market any of our products is successfully challenged, and if we fail to obtain a required license or are unable to design around a patent, our business, financial condition or results of operations could be materially adversely affected.

We may not be able to effectively protect our intellectual property rights.

Patents and other proprietary rights are and will be essential to our business and our ability to compete effectively with other companies will be dependent upon the proprietary nature of our technologies. We also rely upon trade secrets, know-how, continuing technological innovations, strategic alliances and licensing opportunities to develop, maintain and strengthen our competitive position. We pursue a policy of generally obtaining patent protection in both the U.S. and abroad for patentable subject matter in our proprietary devices and also attempt to review third-party patents and patent applications to the extent publicly available to develop an effective patent strategy, avoid infringement of third-party patents, identify licensing opportunities and monitor the patent claims of others. We currently own numerous U.S. and foreign patents. We also are party to various license agreements pursuant to which patent rights have been obtained or granted in consideration for cash or royalty payments. No assurance can be made that any pending or future patent applications will result in issued patents, that any current or future patents issued to, or licensed by, us will not be challenged or circumvented by our competitors, or that our patents will not be found invalid.

In addition, we may have to take legal action in the future to protect our patents, trade secrets or know-how or to assert them against claimed infringement by others. Any legal action of that type could be costly and time consuming to us and no assurances can be made that any lawsuit will be successful.

The invalidation of key patents or proprietary rights that we own, or an unsuccessful outcome in lawsuits to protect our intellectual property, could have a material adverse effect on our business, financial condition or results of operations.

Future product liability claims and other litigation, including private securities litigation and shareholder derivative suits, may adversely affect our business, reputation and ability to attract and retain customers.

The design, manufacture and marketing of medical device products of the types that we produce entail an inherent risk of product liability claims. A number of factors could result in an unsafe condition or injury to, or death of, a patient with respect to these or other products that we manufacture or sell, including component failures, manufacturing flaws, design defects or inadequate disclosure of product-related risks or product-related information. These factors could result in product liability claims, a recall of one or more of our products or a safety alert relating to one or more of our products. Product liability claims may be brought by individuals or by groups seeking to represent a class.

Anyone or any company can bring an action against Misonix.

Our judicial system allows anyone to bring a claim against the Company and force the Company to defend itself even if the claim is baseless. The defense may or may not be covered by the Company's insurance, the result of which could ultimately create a burden on the Company dependent upon the outcome.

We may not be successful in our strategic initiatives to become a medical device company.

Our strategic initiatives intend to further expand our ability to offer customers effective, quality medical devices that satisfy their needs, as well as focus the Company on our medical device platform. If we are unsuccessful in our strategic initiatives, we may be unable to continue to grow our business significantly or may record asset impairment charges in the future.

Our future growth is dependent upon the development of new products, which requires significant research and development, clinical trials and regulatory approvals, all of which are very expensive and time-consuming and may not result in a commercially viable product.

In order to develop new products and improve current product offerings, we focus our research and development programs largely on the development of next-generation and novel technology offerings across multiple programs and opportunities.

As a part of the regulatory process of obtaining marketing clearance from the FDA for new products, we conduct and participate in numerous clinical trials with a variety of study designs, patient populations and trial endpoints. Unfavorable or inconsistent clinical data from existing or future clinical trials conducted by us, by our competitors or by third parties, or the market's perception of this clinical data, may adversely impact our ability to obtain product approvals from the FDA, our position in, and share of, the markets in which we participate and our business, financial condition, results of operations or future prospects.

New products may not be accepted in the market.

We are now, and will continue to be, developing new products and introducing them into the market. There can be no assurance that any new product will be accepted by the market. New products are sometimes introduced into the market in a prototype format and may need later revisions or design changes before they operate in a manner to be accepted in the market. As a result of the introduction of new products, there is some risk that revenue expectations may not be met and in some cases the product may not achieve market acceptance.

We face intense competition and may not be able to keep pace with the rapid technological changes in the medical device industry.

The medical device product market is highly competitive. We encounter significant competition across our product lines and in each market in which our products are sold from various medical device companies, some of which have greater financial and marketing resources than we do.

Additionally, the medical device product market is characterized by extensive research and development and rapid technological change. Developments by other companies of new or improved products, processes or technology may make our products or proposed products obsolete or less competitive and may negatively impact our revenues. We are required to devote continued efforts and financial resources to develop or acquire scientifically advanced technologies and products, apply our technologies cost-effectively across product lines and markets, attract and retain skilled development personnel, obtain patent and other protection for our technology and products, obtain required regulatory and reimbursement approvals and successfully manufacture and market our products. Failure to develop new products or enhance existing products could have a material adverse effect on our business, financial condition or results of operations.

Consolidation in the healthcare industry could lead to demands for price concessions or the exclusion of some suppliers from certain of our significant market segments.

The cost of healthcare has risen significantly over the past decade and numerous initiatives and reforms initiated by legislators, regulators and third-party payers to curb these costs have resulted in a consolidation trend in the healthcare industry, including hospitals. This in turn has resulted in greater pricing pressures and the exclusion of certain suppliers from important market segments as group purchasing organizations, independent delivery networks and large single accounts continue to consolidate purchasing decisions for some of our hospital customers. We expect that market demand, government regulation, third-party reimbursement policies and societal pressures will continue to change the worldwide healthcare industry, resulting in further business consolidations and alliances among our customers and competitors, which may reduce competition, exert further downward pressure on the prices of our products and may adversely impact our business, financial condition or results of operations.

We may experience disruption in supply due to our dependence on our suppliers to continue to ship product requirements and our inability to obtain suppliers of certain components for our products.

Our suppliers may encounter problems during manufacturing due to a variety of reasons, including failure to follow specific protocols and procedures, failure to comply with applicable regulations, equipment malfunctions, labor shortages or environmental factors. In addition, we purchase both raw materials used in our products and finished goods from various suppliers and may have to rely on a single source supplier for certain components of our products where there are no alternatives are available. Although we anticipate that we have adequate sources of supply and/or inventory of these components to handle our production needs for the foreseeable future, if we are unable to secure on a timely basis sufficient quantities of the materials we depend on to manufacture our products, if we encounter delays or contractual or other difficulties in our relationships with these suppliers, or if we cannot find suppliers at an acceptable cost, then the manufacture of our products may be disrupted, which could increase our costs and have a material adverse effect on our business.

If we fail to manage any expansion or acquisition, our business could be impaired.

We may in the future acquire one or more technologies, products or companies that complement our business. We may not be able to effectively integrate these into our business and any such acquisition could bring additional risks, exposures and challenges to the Company. In addition, acquisitions may dilute our earnings per share, disrupt our ongoing business, distract our management and employees, increase our expenses, subject us to liabilities and increase our risk of litigation, all of which could harm our business. If we use cash to acquire technologies, products, or companies, such use may divert resources otherwise available for other purposes. If we use our common stock to acquire technologies, products, or companies, our shareholders may experience substantial dilution. If we fail to manage any expansions or acquisition, our business could be impaired.

Our agreements and contracts entered into with partners and other third parties may not be successful.

We signed in the past and may pursue in the future contracts and agreements with third parties to assist in our marketing, manufacturing, selling and distribution efforts. We cannot assure you that any agreements or arrangements entered into will be successful.

The current disruptions in the financial markets could affect our ability to obtain debt financing on favorable terms (or at all) and have other adverse effects on us.

The United States credit markets have recently experienced historic dislocations and liquidity disruptions which have caused financing to be unavailable in many cases and even if available caused spreads on prospective debt financings to widen considerably. These circumstances have materially impacted liquidity in the debt markets, making financing terms for borrowers able to find financing less attractive, and in many cases have resulted in the unavailability of certain types of debt financing. Continued uncertainty in the credit markets may negatively impact our ability to access debt financing on favorable terms or at all. In addition, Federal legislation to deal with the current disruptions in the financial markets could have an adverse effect on our financial condition and results of operations.

The fluctuation of our quarterly results may adversely affect the trading price of our common stock.

Our revenues and results of operations have in the past and will likely vary in the future from quarter to quarter due to a number of factors, many of which are outside of our control and any of which may cause our stock price to fluctuate. You should not rely on quarter-to-quarter comparisons of our results of operations as an indication of our future performance. It is likely that in some future quarters, our results of operations may be below the expectations of public market analysts and investors. In this event, the price of our common stock may fall.

We may not be able to attract and retain additional key management, sales and marketing and technical personnel, or we may lose existing key management, sales and marketing or technical personnel, which may delay our development and marketing efforts.

We depend on a number of key management, sales and marketing and technical personnel. The loss of the services of one or more key employees could delay the achievement of our development and marketing objectives. Our success will also depend on our ability to attract and retain additional highly qualified management, sales and marketing and technical personnel to meet our growth goals. We face intense competition for qualified personnel, many of whom are often subject to competing employment offers, and we do not know whether we will be able to attract and retain such personnel.

Future changes in financial accounting standards or practices or existing taxation rules or practices may cause adverse or unexpected revenue fluctuations and affect our reported results of operations.

A change in accounting standards or practices or a change in existing taxation rules or practices can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New accounting pronouncements and taxation rules and varying interpretations of accounting pronouncements and taxation practice have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business.

Adverse litigation results could affect our business.

Litigation can be lengthy, expensive and disruptive to our operations, and results cannot be predicted with certainty. An adverse decision could result in monetary damages or injunctive relief that could affect our financial condition, results of operations and cash flows.

The Affordable Healthcare for America Act includes provisions that may adversely affect our business and results of operations, including an excise tax on the sales of most medical devices.

On March 21, 2010, the House of Representatives passed the Affordable Health Care for America Act, which President Obama signed into law on March 23, 2010. While we are continuing to evaluate this legislation and its potential impact on the Company, it may adversely affect our business and results of operations, possibly materially.

Specifically, one of the new law's components is a 2.3% excise tax on sales of most medical devices, starting in 2013. This tax may put increased cost pressure on medical device companies, including our customers, and may lead our customers to reduce their orders for products we produce or to request that we reduce the prices we charge for products we produce in order to offset the tax.

Net sales for the three months ended June 30, 2012 were $5,300,520, an increase of $1,535,086 as compared to $3,765,434 for the three months ended June 30, 2011. The sales increase is due to higher BoneScalpel revenue of $746,820, higher SonaStar revenue of $303,936, higher SonicOne revenue of $243,966 and higher Lysonix revenue of $222,650.

Set forth below are tables showing the Company's net sales by (i) product category and (ii) geographic region for the three months ended June 30, 2012 and June 30, 2011:

Gross profit: Gross profit increased to 58.8% in fiscal 2012 from 57.3% in fiscal 2011. Gross profit for the three months ended June 30, 2012 was 57.7% as compared to 56.7% for the three months ended June 30, 2011 due to increased sales of the BoneScalpel.

Selling expenses: Selling expenses increased $1,146,047 to $5,031,831 (32.2% of sales) in fiscal 2012 from $3,885,784 (31.4% of sales) in fiscal 2011. The increase in selling expenses is related to higher salary expenses of $358,821, higher commissions of $286,308, higher advertising expenses of $192,679, higher travel expenses of $147,773, higher depreciation of demonstration equipment units related to more evaluation units in the field of $151,127 and other unfavorable expenses of $9,339.

The increase in selling expenses is due to increased salary expense of $145,277 (increased headcount) higher travel expense of $43,700, higher depreciation expenses of $23,961 due to new demonstration units in the field and higher advertising expense of $15,901, partially offset by other favorable expenses of $2,490.

General and administrative expenses: General and administrative expenses decreased $122,967 to $4,376,554 in fiscal 2012 from $4,499,521 in fiscal 2011. The decrease in expenses is mainly due to lower accounting expenses of $59,125, lower insurance cost of $49,581 and lower rent expense of $36,141, partially offset by higher consulting expense of $17,264 and other unfavorable expenses of $4,616. For the three months ended June 30, 2012, general and administrative expenses decreased $62,863. This decrease is due to lower legal expense of $23,548, lower employee welfare expense of $16,082, lower insurance expense of $11,186, and other favorable expenses of $12,047.

Research and development expenses: Research and development expenses decreased $139,402 to $1,292,225 in fiscal 2012 from $1,431,627 in fiscal 2011. The decrease is related to lower product development material costs of $112,105 and lower employee welfare costs of $27,481, partially offset by other unfavorable expenses of $184. For the three months ended June 30, 2012, research and development expenses increased $9,347 to $345,241 from $335,894 for the three months ending June 30, 2011.

Other income: Other income decreased $3,689 to $686,189 in fiscal 2012 from $689,878 in fiscal 2011. For the three months ended June 30, 2012, other income increased $24,583 to $136,768 from $112,185 for the three months ended June 30, 2011. The increase is due to lower royalty expenses of $11,936, favorable foreign exchange of $5,483, higher royalty income of $3,130 and other favorable expenses of $4,034.

Income taxes: In fiscal 2012 the income tax benefit for continuing operations had an effective tax rate of 24%. Overall, when considering discontinued operations, the Company had minimal income tax expense. In prior years the Company established a valuation allowance against deferred tax assets due to the net loss from operations over the past 5 years which caused management to conclude that it is more likely than not that its deferred tax assets may not be fully realized.

Discontinued operations:

The following represents the results of the Laboratory and Forensic Safety Products business along with legal and other expenses associated with Labcaire and Misonix HIFU Technologies Limited which are included in discontinued operations:

Critical Accounting Policies:

General: Note 1 of the Notes to Consolidated Financial Statements included in this Annual Report includes a summary of the Company's significant accounting policies and methods used in the preparation of its financial statements. The Company's discussion and analysis of its financial condition and results of operations is based upon the Company's financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an on-going basis, management evaluates its estimates and judgments, including those related to bad debts, inventories, goodwill, property, plant and equipment, stock based compensation and income taxes. Management bases its estimates and judgments on historical experience and on various other factors 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 believes that the following are our more critical estimates and assumptions used in the preparation of our consolidated financial statements:

Accounts Receivable and Allowance for Doubtful Accounts : Accounts receivable, principally trade, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations and adjusts credit limits based upon payment history and the customer's current credit worthiness, as determined by a review of their current credit information. The Company continuously monitors aging reports, collections and payments from customers and maintains a provision for estimated credit losses based upon historical experience and any specific customer collection issues that have been identified. While such credit losses have historically been within expectations and the provisions established, the Company cannot guarantee the same credit loss rates will be experienced in the future. The Company writes off accounts receivable when they become uncollectible.

Inventories : Inventories, consisting of purchased materials, direct labor and manufacturing overhead, are stated at the lower of cost (determined by the first-in, first-out method) or market. At each balance sheet date, we evaluate ending inventories for excess quantities and obsolescence. Our evaluation includes an analysis of historical sales by product, projections of future demand by product, the risk of technological or competitive obsolescence for our products, general market conditions, and the feasibility of reworking or using excess or obsolete products or components in the production or assembly of other products that are not obsolete or for which we do not have excess quantities in inventory. To the extent that we determine there are excess or obsolete quantities, we record valuation reserves against all or a portion of the value of the related products to adjust their carrying value to estimated net realizable value. If future demand or market conditions are different from our projections, or if we are unable to rework excess or obsolete quantities into other products, we may change the recorded amount of inventory valuation reserves through a charge or reduction in cost of product revenues in the period the revision is made.

Long Lived Assets : Property, plant and equipment are recorded at cost. Minor replacements and maintenance and repair expenses are charged to expense as incurred. Depreciation of property and equipment is provided using the straight-line method over estimated useful lives ranging from 3 to 5 years. Leasehold improvements are amortized over the life of the lease or the useful life of the related asset, whichever is shorter. Inventory items included in property, plant and equipment are depreciated using the straight line method over estimated useful lives of 3 to 5 years. We evaluate long-lived assets, including property, plant and equipment and intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amounts of specific assets or group of assets may not be recoverable. When an evaluation is required, we estimate the future undiscounted cash flows associated with the specific asset or group of assets. If the cost of the asset or group of assets cannot be recovered by these undiscounted cash flows, an impairment charge would be recorded. Our estimates of future cash flows are based on our experience and internal business plans. Our internal business plans require judgments regarding future economic conditions, product demand and pricing. Although we believe our estimates are appropriate, significant differences in the actual performance of an asset or group of assets may materially affect our evaluation of the recoverability of the asset values currently recorded.

Revenue Recognition : The Company records revenue upon shipment for products shipped F.O.B. shipping point. Products shipped F.O.B. destination points are recorded as revenue when received at the point of destination. Shipments under agreements with distributors are not subject to return and payment for these shipments is not contingent on sales by the distributor. Accordingly, the Company recognizes revenue on shipments to distributors in the same manner as with other customers. Fees from exclusive license agreements are recognized ratably over the terms of the respective agreements. Service contract and royalty income are recognized when earned.

Goodwill : Goodwill is not amortized. We review goodwill for impairment annually and whenever events or changes indicate that the carrying value of an asset may not be recoverable. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of significant assets or products. Application of these impairment tests requires significant judgments, including estimation of cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, the useful life over which cash flows will occur and determination of our weighted-average cost of capital. Changes in the projected cash flows and discount rate estimates and assumptions underlying the valuation of goodwill could materially affect the determination of fair value at acquisition or during subsequent periods when tested for impairment. The Company completed its annual goodwill impairment tests for fiscal 2012 and 2011 in the respective fourth quarter. No impairment of goodwill was deemed to exist.

Income Taxes : Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Significant judgment is required in determining the realizability of deferred tax assets including estimates of future sufficient taxable income to support the recovery of tax assets.

Financial accounting standards establish guidance for the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. The Company may recognize the tax benefits from an uncertain tax position only it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Financial accounting standards also provide guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosures requirements.

Stock-Based Compensation : The fair value of the Company's outstanding stock options is estimated based upon option price, volatility, the risk free rate, and the average time the shares are held. It is then amortized over the vesting period. See Note 7 to the Company's consolidated financial statements for additional information regarding stock-based compensation.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended ("Exchange Act")) that are designed to assure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the rules and formsof the SEC, and that such information is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures.

As required by Exchange Act Rule 13a-15(b), as of the end of the period covered by this Annual Report, under the supervision and with the participation of our principal executive officer and principal financial officer, we evaluated the effectiveness of our disclosure controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of that date. This is in accordance with Section 404(a) of the Sarbanes-Oxley Act of 2002 ("SOX") because the Company is a smaller reporting company under the SEC's rules. We are not required to be in compliance with SOX 404(b), which requires attestation by a company's independent auditors.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, the principal executive officer and principal financial officer, and affected by the board of directors and management to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") including 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 assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that receipts and expenditures are being made only in accordance with authorizations of management and the directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements.

The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) 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 (3) 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 financial statements.

Because of its inherent limitations, internal control over financial reporting 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.

Management conducted an evaluation of the effectiveness of the internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that internal control over financial reporting was effective as of June 30, 2012.  In order to assist in the testing of our internal controls, the Company engaged a third- party to assist in the testing and evaluation of our internal control systems.

This Annual Report does not include an attestation report of the Company's current independent registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by the Company's current independent registered public accounting firm pursuant to rules of the SEC that permit the Company to provide only management's report in this Annual Report.

Changes in Internal Control over Financial Reporting.

There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during our fourth fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information.

Item 11. Executive Compensation.

Compensation Discussion and Analysis

Overview of Compensation Program and Philosophy

Our compensation program is intended to:

The ultimate objective of our compensation program is to increase shareholder value. We seek to achieve these objectives with a total compensation approach which takes into account a competitive base salary, bonus pay based on the annual performance of the Company and individual goals and stock option awards.

Base Salaries

Base salaries paid to executives are intended to attract and retain highly talented individuals. In setting base salaries, individual experience, individual performance, the Company's performance and job responsibilities during the year are considered. Executive salaries are reconciled by Human Resources and evaluated against local companies of similar size and nature.

Annual Bonus Plan Compensation

The Compensation Committee of the Board approves annual performance-based compensation. The purpose of the annual bonus-based compensation is to motivate executive officers and key employees. Target bonuses, based upon recommendations from the Chief Executive Officer, are evaluated and approved by the Compensation Committee for all management employees other than the Chief Executive Officer. The bonus recommendations are derived from individual and Company performance but not based on a specific formula and are discretionary. The Chief Executive Officer's bonus compensation is derived from the recommendation of the Compensation Committee based upon the Chief Executive Officer's performance and Company performance but is not based on a specific formula and is discretionary.

Stock Option Awards

Stock option awards are intended to attract and retain highly talented executives, to provide an opportunity for significant compensation when overall Company performance is reflected in the stock price and to help align executives' and shareholders' interests. Stock options are typically granted at the time of hire to key new employees and annually to a broad group of existing key employees, including executive officers.

Annual option grants to executive officers are made in the form of incentive stock options ("ISOs") to the fullest extent permitted under tax laws, with the balance granted in the form of nonqualified stock options. ISOs have potential income tax advantage for executives if the executive disposes of the acquired shares after satisfying certain holding periods. Tax laws provide that the aggregate grant at date of grant for market value of ISOs that become exercisable for any employee in any year may not exceed $100,000.

Our current standard vesting schedule for all employees is 25% on the first anniversary of the date of grant, 50% on the second anniversary of the date of grant, 75% on the third anniversary of the date of grant and 100% on the fourth anniversary of the date of grant.

401 (k) Plan

Our Individual Deferred Tax and Savings Plan (the "401 (k) plan") is a tax qualified retirement savings plan pursuant to which all of the Company's U.S. employees may defer compensation under Section 401 (k) of the Internal Revenue Code of 1986, as amended (the "Code"). The Company contributes an amount equal to 10% of salary contributed under the 401 (k) plan by an eligible employee, up to the maximum allowed under the Code. We do not provide any supplemental retirement benefits to executive officers.

Change in Control benefits

Change in control benefits are intended to diminish the distraction that executives would face by virtue of the personal uncertainties created by a pending or threatened change in control and to assure that the Company will continue to have the executive's full attention and services at all time. Our change in control benefits are designed to be competitive with similar benefits available at companies with which we compete for executives' talent. These benefits, as one element of our total compensation program, help the Company attract, retain and motivate highly talented executives.

Mr. McManus is entitled to severance pay and benefits if he terminates his employment with the Company following a Change in Control (as defined in the Employment Agreement), to provide him with an incentive to remain with the Company and consummate a strategic corporate sale or transaction that maximizes shareholder value. Severance pay and benefits are triggered upon (i) his Involuntary Termination without Cause (as defined in the Employment Agreement) for a reason other than death or Disability (as defined in the Employment Agreement) or (ii) as a result of a Constructive Termination (as defined in the Employment Agreement) which in either case occurs: (x) during the period not to exceed twenty-four (24) months after the effective date of a Change in Control, or (y) before the effective date of a Change in Control, but after the first date on which the Board and/or senior management of the Company has entered into formal negotiations with a potential acquirer that results in the consummation of a Change in Control.

In the event that pay and benefits are triggered, Mr. McManus (A) is entitled to receive severance pay in an amount equal to two (2) times the sum of (a) his annual base pay and (b) bonus at the highest rate paid him for any fiscal year during the aggregate period of his employment by the Company, payable in cash in a lump sum; and the payment of premiums for medical, dental, vision, hospitalization and long term care coverage under Company plans for a period of twenty-four (24) months; (B) has the right, for a period of (i) ninety (90) days for stock options granted under any of the Company's Employee Stock Option Plans adopted prior to 2005 and (ii) two (2) years for stock options granted under the Company's 2005 Employee Equity Incentive Plan, 2009 Employee Equity Incentive Plan and any Plan adopted after the effective date of the Employment Agreement following his Termination Date (as defined in the Employment Agreement), to exercise the options to the extent such options are otherwise vested and exercisable as of the Termination Date under the terms of the applicable stock option agreement(s) and Plan(s); and (C) will vest in all unvested stock option grants with respect to options granted after July 1, 2012.

Mr. Zaremba and Mr. Ryan have an agreement for the payment of twelve months of annual base salary upon a change in control of the Company.

Tax deductibility of Executive Compensation

Section 162 (m) of the Code limits to $1,000,000 per person the amount that we may deduct for compensation paid to any of our most highly compensated officers in any year. In fiscal 2012, there was no executive officer's compensation that exceeded $1,000,000.

The following table sets forth information concerning the compensation awarded to, earned by or paid to our named executive officers during the past two fiscal years for services rendered to the Company:

SUMMARY COMPENSATION TABLE

On September 11, 2012, the Company entered into a new Employment Agreement with Michael A.

Mr. McManus is entitled under the Employment Agreement to participate in any plans and programs made available to the executive employees of the Company generally.

The Company can terminate the Employment Agreement for cause (as defined in the Employment Agreement). Mr. McManus can terminate the Employment Agreement for good reason (as defined in the Employment Agreement). If Mr. McManus terminates the Employment Agreement for good reason, the Company must pay him an amount equal to two times his total compensation (annual base salary plus bonus) at the highest rate paid him at any time during the aggregate time he has been employed by the Company, payable in a lump sum within sixty (60) days of termination of employment.

The Company and Mr. McManus have entered into two letter agreements providing for the exercise of vested options by Mr. McManus (i) for a ninety (90) day period after his retirement with respect to stock options granted under certain of the Company's stock option plans and (ii) for two (2) years after Mr. McManus terminates his employment with the Company in the event of a Change-in-Control (as defined in the applicable stock option plans) and he is eligible for the severance benefits provided for by the Employment Agreement. 

In conformity with the Company's policy, all officers and employees have executed a non-solicitation and confidentiality agreement. The agreements generally provide that all inventions or discoveries by the employee related to the Company's business and all confidential information developed or made known to the employee during the term of employment shall be the exclusive property of the Company and shall not be disclosed to third parties without the prior approval of the Company. The Employment Agreement also contains non-competition provisions that preclude him from competing with the Company for a period of 18 months from the date of his termination of employment.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

MISONIX, INC. and Subsidiaries

We have audited the accompanying consolidated balance sheets of MISONIX, INC. and Subsidiaries (the "Company") as of June 30, 2012 and 2011, and the related consolidated statements of operations, stockholders' equity and cash flows for the years then ended. Our audits of the basic consolidated financial statements included the financial statement schedule listed in the index appearing under Item 15(a)(2). These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We 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 audit to obtain reasonable assurance about whether the 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 control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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 also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 financial position of MISONIX, INC. and Subsidiaries as of June 30, 2012 and 2011 and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
