NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

November 30, 2012 and November 30, 2011

(unaudited)

NOTE A – CONSOLIDATED FINANCIAL STATEMENTS

The consolidated balance sheet as of November 30, 2012, the consolidated statement of stockholders’ equity and the consolidated statement of cash flows for the six months ended November 30, 2012 and the consolidated statements of income and the consolidated statements of comprehensive income for the three and six months ended November 30, 2012 and November 30, 2011 have been prepared by us without audit. The consolidated balance sheet as of May 31, 2012 was derived from audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments (which include only normally recurring adjustments) necessary to state fairly the financial position, changes in stockholders’ equity and comprehensive income, results of operations and cash flows as of and for the period ended November 30, 2012 (and for all periods presented) have been made.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. It is suggested that these unaudited interim consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended May 31, 2012, filed by us on August 14, 2012. Our most significant accounting policies are disclosed in Note A to the consolidated financial statements included in the aforementioned Form 10-K for the fiscal year ended May 31, 2012. The results of operations in the fiscal periods ended November 30, 2012 and November 30, 2011 are not necessarily indicative of the operating results for the respective full fiscal years.

The unaudited interim consolidated financial statements for the three and six months ended November 30, 2012 and November 30, 2011 include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, RITA Medical Systems, LLC, AngioDynamics UK Limited, AngioDynamics Netherlands B.V., NM Holding Company, Inc. (Navilyst) since May 22, 2012 and Vortex Medical, Inc. since October 15, 2012 (collectively, the “Company”). All intercompany balances and transactions have been eliminated.

Effective June 1, 2012, we consider our business to be a single segment entity – the development, manufacture and sale on a global basis of medical devices for vascular access, surgery, peripheral vascular disease and oncology. Our chief operating decision maker (CEO) evaluates the various global product portfolios on a net sales basis. Executives reporting in to the CEO include those responsible for operations and supply chain management, research and development, sales, franchise marketing and certain corporate functions. The CEO evaluates profitability, investment and cash flow metrics on a consolidated worldwide basis due to shared infrastructure and resources. Prior to fiscal year 2013, our business was organized as two segments: Vascular and Oncology/Surgery, each under the direction of a general manager with direct responsibility for all sales, marketing and product development activities.

We have performed an evaluation of subsequent events through the date the financial statements were issued.

Acquisition of Vortex Medical Inc.

On October 15, 2012, we acquired all the outstanding capital stock of Vortex Medical, Inc., a privately-held company focused on the development and commercialization of medical devices for venous drainage and the removal of thrombus, or blood clots, from occluded blood vessels. Vortex’s principal product is the AngioVac ^® system, which includes the AngioVac Cannula and Circuit. The AngioVac Cannula has a proprietary balloon-actuated, expandable, funnel-shaped distal tip that enhances flow, prevents clogging of the cannula and facilitates en bloc, or whole removal of undesirable intravascular material. Both the AngioVac Cannula and Circuit are FDA-cleared for use during extracorporeal bypass for up to 6 hours. An application for CE Mark approval has been filed.

The total estimated purchase consideration of $75.4 million includes an upfront payment of $15.1 million and the estimated fair value of contingent (Earn out) consideration of $60.3 million. The estimated fair value of contingent consideration is based on projected Angio Vac net sales in the ten year period following the closing. The amount of the Earn out consideration that could be paid on Angio Vac net sales is not limited.

The estimated purchase consideration exceeds the fair value of the acquired net assets by $30.0 million and was recorded as goodwill. Goodwill is not deductible for tax purposes. Core technologies are being amortized over their estimated useful lives of approximately 15 years as revenues are earned from the sales of related products. We incurred acquisition related costs of $325 thousand, which were expensed to “Acquisition, restructuring and other items, net” in the statement of income. We have not finalized the purchase accounting, which may be adjusted as further information about conditions existing at the acquisition date becomes available. See Note B for additional information.

NOTE A – CONSOLIDATED FINANCIAL STATEMENTS – cont’d

Regulatory Matters

On May 27, 2011, we received a Warning Letter from FDA in connection with its inspection of our Queensbury, NY manufacturing facility. In the Warning Letter, FDA cited deficiencies in the response letter we provided FDA pertaining to the inspection that occurred from January 4 to January 13, 2011. The deficiencies related to our internal procedures for medical device reporting, corrections and removals and complaint handling. We responded to the Warning Letter and completed corrective and preventive actions to address the observations noted.

In December 2011, we initiated a comprehensive Quality Call to Action Program to review and augment our Quality Management Systems at our Queensbury facility. To accelerate implementation of the program, we engaged a team of external regulatory and quality experts and reallocated a significant number of engineering and product development resources to support this corporate initiative. From inception of the Quality Call to Action Program through the second fiscal quarter of 2013, we have incurred $3.1 million in direct costs associated with the program.

On February 10, 2012, we received from FDA a Form 483, List of Investigational Observations, in connection with its inspection of our Queensbury facility from November 14, 2011 to February 10, 2012. The Form 483 contained 12 observations related to, among other things, our CAPA (Corrective and Preventive Action) system, MDR (Medical Device Reporting), complaint investigation, corrections and removals, acceptance criteria and training. Some of the observations contained in the Form 483 were repeat observations from the May 27, 2011 Warning Letter.

On February 13, 2012, we received from FDA a Form 483 in connection with its inspection of our Fremont facility from January 12, 2012 to February 13, 2012. The Form 483 contained six observations related to, among other things, our CAPA system, design controls, risk management and training. We provided responses to FDA within 15 business days of our receipt of the Form 483s.

On September 24, 2012, we received from FDA a Form 483 in connection with its subsequent inspection of our Queensbury, NY facility from September 6 to September 14, and September 19 and September 24. This re-inspection followed our response to the original Form 483 issued by FDA on February 13, 2012. The Form 483 contained 5 observations related to 510(k) decisions, complaint investigations, acceptance criteria, corrective and preventive actions and training. All but one of the observations in the Form 483 related to events that occurred before the date that we had indicated to FDA in our previous responses that our corrective and remediation activities related to our Quality Call to Action would be completed. We provided responses to FDA within 15 business days of our receipt of the Form 483.

On November 28, 2012, FDA completed an inspection of our Manchester, GA facility and no Form 483 observations were issued.

We will continue to work closely with FDA to resolve any outstanding issues. Unless the items raised in the previously disclosed Warning Letters and Form 483s are corrected to FDA’s satisfaction or we come to some other arrangement with FDA finally resolving such matters, we may be subject to additional regulatory or legal action, including the issuance of warning letters, injunction, seizure or recall of products, imposition of fines or penalties or operating restrictions on our facilities. Such actions could significantly disrupt our ongoing business and operations and have a material adverse impact on our financial position and operating results.

In May 2011, we submitted to FDA an application for an Investigational Device Exemption for a clinical trial to study the use of NanoKnife in the treatment of pancreatic cancer. In June 2012, we submitted an amendment to our application to address matters raised by FDA in the course of their review of the application and to propose an expanded and enhanced controlled, randomized trial protocol. In August 2012, we received a disapproval letter from FDA requesting additional information and certain protocol changes. We intend to continue to work with FDA to address the matters raised in the August letter.

Expiration of our Distribution Agreement Amendment for LC Bead

The Supply and Distribution Agreement with Biocompatibles UK Limited, which granted us exclusive distribution rights to LC Beads in the United States, expired on December 31, 2011. LC Bead sales were $9.1 million and $17.1 million in the three and six months ending November 30, 2011, respectively.

Acquisition, restructuring and other items, net

Navilyst Acquisition Costs

The three and six month periods ended November 30, 2012 include approximately $1.7 million and $3.9 million, respectively, in transaction and severance costs related to the Navilyst acquisition. These costs are included in “Acquisition, restructuring and other items, net” in the statement of operations. See Note B for additional information.

Closure of UK facility

During the first fiscal quarter of 2012, we made the decision to close our Cambridge, UK facility and transfer the production of lasers to our Queensbury, NY facility. We subsequently extended the date for closing the UK facility and moving laser manufacturing from December 2011 to December 2012. We estimate the total cost of this project will be approximately $3.4 million. The income statements for the three month periods ending November 30, 2012 and November 30, 2011 include charges of $279 thousand and $587 thousand, respectively, for costs incurred associated with this closure. The income statements for the six month periods ending November 30, 2012 and November 30, 2011 include charges of $616 thousand and $883 thousand, respectively, for costs incurred associated with this closure. The charge is included in “Acquisition, restructuring and other items, net” in the income statement.

NOTE B – ACQUISITIONS

Acquisition of Vortex Medical, Inc.

On October 15, 2012, we acquired all the outstanding capital stock of Vortex Medical, Inc., a privately-held company focused on the development and commercialization of medical devices for venous drainage and the removal of thrombus, or blood clots, from occluded blood vessels. Vortex’s principal product is the AngioVac ^® system, which includes the AngioVac Cannula and Circuit. The AngioVac Cannula has a proprietary balloon-actuated, expandable, funnel-shaped distal tip that enhances flow, prevents clogging of the cannula and facilitates en bloc, or whole removal of undesirable intravascular material. Both the AngioVac Cannula and Circuit are FDA-cleared for use during extracorporeal bypass for up to 6 hours. An application for CE Mark approval has been filed.

The stock purchase agreement provided for the payment of $15.1 million in cash at closing, which is subject to a working capital adjustment, plus future earn out consideration payable in cash. Earn out consideration is based on our net sales of the AngioVac system during the ten years following the closing, payable in the amount of 10% of annual net sales up to $150 million, 12.5% of annual net sales between $150 million and $500 million, and 15% of annual net sales above $500 million. The Earn out consideration is subject to guaranteed minimum payments payable on the anniversary dates following closing, in the amounts of $8.35 million on the first, $8.0 million on the second, third and fourth, and $7.65 million on the fifth anniversary date. If a minimum payment for a period exceeds the contingent earn out payment for the same period, the amount of the excess will be credited against future contingent earn out payments.

The total estimated purchase consideration of $75.4 million includes the upfront payment of $15.1 million and the estimated fair value of contingent consideration of $60.3 million. The estimated fair value of contingent consideration is based on projected AngioVac net sales in the ten year period following the closing. The amount of the Earn out consideration that could be paid on AngioVac net sales is not limited.

The Vortex historical financial results were not significant and therefore pro forma results would not be substantially different. Sales since the acquisition closed are negligible and the operations of Vortex have been fully integrated from the date of acquisition.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed (in thousands):

Cash and cash equivalents	$	339
Accounts receivable		200
Inventories		488
Other assets		6
Deferred tax assets		1,307
Intangibles		72,430
Goodwill		30,019
Total assets acquired		104,789
Deferred tax liabilities		(28,451	)
Liabilities assumed		(931	)
Total purchase price	$	75,407
Up front payment	$	15,105
Present value of contingent consideration liability		60,302
Total purchase price	$	75,407

The estimated purchase consideration exceeds the fair value of the acquired net assets by $30.0 million and was recorded as goodwill. Goodwill is not deductible for tax purposes. Core technologies are being amortized over their estimated useful lives of approximately 15 years as revenues are earned from the sales of the related products. We incurred acquisition related costs of $325 thousand, which were expensed to “Acquisition, restructuring and other items, net” in the statement of income. We have not finalized the purchase accounting, which may be adjusted as further information about conditions existing at the acquisition date becomes available.

Acquisition of Navilyst

On May, 22, 2012, we completed the acquisition of privately-held Navilyst, a global medical device company with strengths in the vascular access, interventional radiology and interventional cardiology markets. The acquisition and related transaction costs were financed through the issuance of approximately 9.5 million shares of our common stock, $150 million in drawn acquisition debt financing and $97 million of cash. Based on the closing price of our stock of $12.44 on the day prior to the transaction, the purchase price was approximately $361 million.

The three and six month periods ended November 30, 2012 include approximately $1.7 million and $3.9 million, respectively, in transaction and severance costs related to the Navilyst acquisition. These costs are included in “Acquisition, restructuring and other items, net” in the statement of income. Investment funds affiliated with Avista Capital Partners, former owners of Navilyst, received approximately 9.5 million shares of our common stock and, as of November 30, 2012, held approximately 27% of our outstanding shares. Investment funds affiliated with Avista Capital Partners entered into a stockholders agreement with us as part of the transaction and also appointed two additional directors to our existing Board of Directors.

To satisfy any working capital adjustment and potential indemnification claims that may arise, $19.1 million of purchase consideration has been placed in escrow, including approximately $14.0 million in cash and approximately 415 thousand shares of common stock, determined based on the closing price of $12.44 on the day prior to the transaction. The indemnification claims period will terminate on July 15, 2013. At May 31, 2012 and November 30, 2012, we had $2.5 million of receivable related to the working capital adjustment recorded as escrow receivable on the balance sheet.

NOTE B – ACQUISITIONS – (cont’d)

Goodwill recorded as a result of the acquisition was $145.2 million. Intangible assets acquired, other than goodwill, totaled approximately $107.1 million, of which $49.4 million has been identified as customer relationships (15-year weighted average useful life), $32.5 million of trademarks (of which $28.6 million has been determined to have an indefinite useful life and the remaining $3.9 million has a 7 year weighted average useful life), $15.1 million of in-process research and development (indefinite useful life until completed) and $10.1 million of technology (6-year weighted average useful life).

The IPR&D assets, which were accounted for as indefinite-lived assets at the time of acquisition, represent the development of a biomedical polymer additive for use in PICC and other vascular access product lines and a power injectable port which are valued at $12.1 million and $3.0 million, respectively. The biomedical polymer additive product recently received regulatory approval and the product was released in the United States in October 2012 and is being amortized over a 10 year useful life. The power injectable port is expected to be released in the United States in fiscal 2013, subject to regulatory approvals. The fair value of these intangible assets was determined based upon the present value of expected future cash flows adjusted for the probability of technological and commercial risk, utilizing a risk-adjusted discount rate.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of the acquisition (in thousands):

	May 22, 2012
Cash and cash equivalents	$	7,683
Accounts receivable		19,069
Inventories		26,851
Prepaid expenses and other current assets		5,504
Property, plant and equipment		34,017
Deferred tax assets		33,709
Goodwill		145,221
Intangibles		107,100
Other long-term assets		497
Total assets acquired		379,651
Liabilties assumed		(18,287	)
Total net assets acquired	$	361,364

The purchase price allocation is subject to change as additional information becomes available concerning the fair value and tax basis of the acquired assets and liabilities. Any adjustment to the purchase price allocation will be made as soon as practicable but no later than one year from May 22, 2012, the acquisition date. See Note D for additional information about changes in the carrying amount of goodwill.

Investment in Microsulis Medical Ltd

On March 22, 2012, we established a strategic relationship with Microsulis Medical Ltd., a U.K.-based company specializing in minimally-invasive, microwave ablation technology for the coagulation of soft tissue.

The relationship includes a $5 million investment in Microsulis through the purchase of senior preferred stock, representing a 14.3% ownership position, exclusive distribution rights to market and sell their microwave ablation systems in all markets outside the United States from May 2012 through December 2013, and an exclusive option to purchase at any time until September 22, 2013, substantially all of the global assets of Microsulis Medical, Ltd. We have accounted for the investment under the cost method. The $5 million investment is included in intangible assets and other non-current assets on the balance sheet at November 30, 2012 and May 31, 2012.

NOTE C – INVENTORIES

Inventories are stated at lower of cost (at standard cost which approximates the first-in, first-out method) or market. Inventories consist of the following:

NOTE D – GOODWILL AND INTANGIBLE ASSETS

As previously discussed, effective June 1, 2012 we implemented a change to our internal reporting structure and we now view the business as one operating segment. In connection with this change, we have also re-assessed our reporting units in accordance with ASC 350 and have determined that, effective June 1, 2012 we have one reporting unit for goodwill impairment testing purpose. We have considered these internal structural changes and their potential impact as it relates to testing goodwill for impairment. We have assessed these changes from a qualitative perspective in determining whether it is more likely than not that the fair value of our single reporting unit is less than its carrying value as a basis for determining whether it is necessary for us to perform a two-step goodwill impairment test. Based on our qualitative assessment, we have determined that it is not more likely than not that the fair value of our reporting unit is less than its carrying value and therefore, goodwill is not impaired.

Changes in the carrying amount of goodwill for the six months ended November 30, 2012 are as follows (in thousands):

Balance, May 31, 2012	$	308,912
Adjustments to purchase price		(1,741	)
Goodwill acquired from Vortex		30,019
Balance, November 30, 2012	$	337,190

The above $1.7 million reduction in the carrying value of goodwill is the result of an $858,000 payment from Avista Capital Partners and an $883,000 increase in the value of deferred tax assets from the Navilyst acquisition.

NOTE F – LONG TERM DEBT

Bank Credit Agreement

In connection with the Navilyst acquisition, we entered into a Credit Agreement with a group of banks which provided a $150 million senior secured term loan facility and a $50 million senior secured revolving credit facility. The $150 million in proceeds from the term loan were used to finance a portion of the consideration for the acquisition. The revolving facility may be used for general corporate purposes and was undrawn at November 30, 2012. Both facilities have five year maturities. The term facility has a quarterly repayment schedule equal to 5%, 5%, 15%, 25% and 50% of its principal amount in years one through five. The credit agreement contains certain financial covenants relating to fixed charge coverage and leverage, as defined, with which we were in compliance at November 30, 2012. Amounts borrowed under the Credit Agreement are collateralized by all our assets. Interest on both the term loan and the revolving loan is based on a base rate or Eurodollar rate plus an applicable margin with increases as our total leverage ratio increases, and with the base rate and Eurodollar rate have ranges of 1.0% to 1.75% and 2.0% to 2.75% respectively. In the event of default, the interest rate may be increased by 2.0%. The revolving facility will also carry a commitment fee of 0.30% to 0.50% per year on the unused portion. As of November 30, 2012, net deferred financing costs of $2.2 million are recorded as a component of other assets on the balance sheet and are being amortized over the remaining life of the related debt.

In June 2012, we entered in an interest rate swap agreement, with an initial notional amount of $100 million, to limit the effect of rising of interest rates. The Swap Agreement, which qualifies for hedge accounting under authoritative guidance, is a contract to exchange floating interest rate payments for fixed interest rate payments on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement.

NOTE G – INCOME TAXES

Our effective income tax rate for the three month periods ending November 30, 2012 and November 30, 2011 was 37% and 35%, respectively. Our effective income tax rate for the six month periods ending November 30, 2012 and November 30, 2011 was 37% and 35%, respectively.

NOTE H – EARNINGS PER COMMON SHARE

Basic earnings per share are based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share further includes the dilutive effect of potential common stock consisting of stock options, warrants, and restricted stock units, provided that the inclusion of such securities is not antidilutive.

The following table sets forth the reconciliation of the weighted-average number of common shares (in thousands):

	Three Months Ended				Six Months Ended
	Nov 30, 2012		Nov 30, 2011		Nov 30, 2012		Nov 30, 2011

Effect of dilutive securities		484		150		514		171
Diluted		35,311		25,340		35,279		25,278

Excluded from the calculation of diluted earnings per common share were options and restricted stock awards issued to employees and non-employees to purchase 3.2 million and 3.0 million shares of common stock for the three and six months ended November 30, 2012, respectively, as their inclusion would be antidilutive. For the comparable three and six month period ended November 30, 2011, options and restricted stock awards issued to employees and non-employees to purchase 2.4 million and 2.1 million shares of common stock were also excluded as their inclusion would be antidilutive.

NOTE I – SEGMENT AND GEOGRAPHIC INFORMATION

Effective June 1, 2012, we consider our business to be a single segment entity – the development, manufacture and sale on a global basis of medical devices for vascular access, surgery, peripheral vascular disease and oncology. Our chief operating decision maker (CEO) evaluates the various global product portfolios on a net sales basis. Executives reporting in to the CEO include those responsible for operations and supply chain management, research and development, sales, franchise marketing and certain corporate functions. The CEO evaluates profitability, investment and cash flow metrics on a consolidated worldwide basis due to shared infrastructure and resources. Prior to fiscal year 2013, our business was organized as two segments: Vascular and Oncology/Surgery, each under the direction of a general manager with direct responsibility for all sales, marketing and product development activities.

NOTE J – FAIR VALUE

Our financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable, interest rate swap agreement and the contingent Earn out related to the acquisition of Vortex. The carrying amount of cash and cash equivalents, accounts receivable, marketable securities and accounts payable approximates fair value due to the immediate or short-term maturities. The interest rate swap agreement has been recorded at its fair value based on a valuation received from an independent third party. Marketable securities, with the exception of auction rate securities, are carried at their fair value as determined by quoted market prices. The contingent Earn out has been recorded at fair value using a discounted cash flow model.

Per our accounting policy, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This policy establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The policy describes three levels of inputs that may be used to measure fair value which are provided in the table below.

NOTE J – FAIR VALUE – (cont’d)

Level 1	Quoted prices in active markets for identical assets or liabilities. Level 1 assets include bank time deposits, money market funds, mutual funds and U.S. Treasury securities that are traded in an active exchange market.
Level 2	Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include US government securities and corporate bonds. When quoted market prices are unobservable, we obtain pricing information from an independent pricing vendor. The pricing vendor uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. Since many fixed income securities do not trade on a daily basis, the methodology of the pricing vendor uses available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The pricing vendor considers all available market observable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted prices, but rather determined from market observable information. These investments are included in Level 2 and primarily comprise our portfolio of corporate and government fixed income securities. Additionally included in Level 2 are interest rate swap agreements which are valued using a mid-market valuation model.
Level 3	Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category currently includes the auction rate securities where independent pricing information was not able to be obtained and the contingent Earn out related to the acquisition of Vortex. Our investments in auction-rate securities were classified as Level 3 as quoted prices were unavailable since these auction rate securities issued by New York state and local government authorities failed auction. Due to limited market information, we utilized a discounted cash flow (“DCF”) model to derive an estimate of fair value for all periods presented. The assumptions used in preparing the DCF model included estimates with respect to the amount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk associated with auction-rate securities. The contingent Earn out was valued utilizing a discounted cash flow method as detailed below.

Contingent Liability for Acquisition Earn Out

The total estimated purchase consideration related to the acquisition of Vortex Medical, Inc. included an estimated fair value of contingent or earn out consideration. The fair value of the contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within acquisition-related items in the condensed consolidated statements of earnings. We measure the initial liability and remeasure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements.

Contingent consideration liabilities will be remeasured to fair value each reporting period using projected net sales, discount rates, probabilities of payment and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected net sales are based on our internal projections and extensive analysis of the target market and the sales potential. Increases in projected net sales and probabilities of payment may result in higher fair value measurements in the future. Increases in discount rates and the projected time to payment may result in lower fair value measurements in the future. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in the future.

NOTE J – FAIR VALUE – (cont’d)

The recurring Level 3 fair value measurements of the contingent consideration liability include the following significant unobservable inputs ($ in millions):

	Fair value at Nov 30, 2012		Valuation Technique	Unobservable Input	Range
Net sales based payments	$	60.5	Discounted	Discount rate	4%
			cash flow	Probability of payment	75-100%
				Projected fiscal year of payment	2013 - 2022

At November 30, 2012, the estimated potential amount of undiscounted future contingent consideration that we expect to pay as a result of this acquisition is approximately $75 million. The milestones associated with the contingent consideration must be reached in future periods ranging from fiscal years 2013 to 2023 in order for the consideration to be paid.

The fair value of contingent milestone payments associated with the Vortex acquisition was remeasured as of November 30, 2012 and $52.4 million was reflected in “Contingent consideration, net of current portion” and $8.1 million was reflected in “Current portion of contingent consideration” on the condensed consolidated balance sheet.

NOTE K – MARKETABLE SECURITIES

Marketable securities, which are principally government agency bonds, auction rate investments and corporate commercial paper, are classified as “available-for-sale securities” in accordance with authoritative guidance issued by FASB and are reported at fair value, with unrealized gains and losses excluded from operations and reported as accumulated other comprehensive income (loss), net of the related tax effects, in stockholders’ equity. Cost is determined using the specific identification method. We hold investments in auction rate securities in order to generate higher than typical money market rate investment returns. Auction rate securities typically are high credit quality, generally achieved with municipal bond insurance. Credit risks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids and, in such cases, the auction fails and we may be unable to liquidate our position in the securities in the near term. As of November 30, 2012 and May 31, 2012, we had $1.85 million in investments in two auction rate securities issued by New York state and local government authorities that failed auctions. The authorities are current in their interest payments on the securities.

Marketable securities as of November 30, 2012 consisted of the following:

	Amortized cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value

NOTE L – LITIGATION

AngioDynamics v. biolitec

On January 2, 2008, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. biolitec, Inc. In this action, we are seeking judgment against biolitec for defense and indemnification in two lawsuits which we previously settled. Our claims arise out of a Supply and Distribution Agreement (“SDA”) entered into with biolitec on April 1, 2002. On September 27, 2011, the U.S. District Court for the Northern District of New York granted key portions of our motion for summary judgment in our legal case against biolitec. The Court’s order was filed under seal. The Court also dismissed biolitec’s counterclaims against us. The court denied one portion of our summary judgment motion, which sought to recover additional costs from biolitec, leaving this for adjudication at trial. On September 28, 2012, the Court granted partial judgment to us in the amount of $16.4 million, along with pre-judgment interest.

In October 2009, we commenced an action in the United States District Court for the District of Massachusetts entitled AngioDynamics, Inc. v. biolitec AG and Wolfgang Neuberger. The Complaint in this action was amended in March 2010. This action seeks to recover against biolitec, Inc.’s parent entities and CEO for tortiously interfering with biolitec, Inc.’s contractual obligation to defend and indemnify us, and also seeks to pierce the corporate veil of biolitec, Inc. and to invalidate certain alleged fraudulent transfers in order to hold biolitec, Inc.’s parent entities jointly and severally liable for the alleged breach of the SDA. This case is currently in the discovery phase. On September 13, 2012, the Massachusetts Court granted our request for a preliminary injunction prohibiting the downstream merger of biolitec AG with its Austrian subsidiary.

We will continue to vigorously enforce our rights under the supply agreement with biolitec.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. filed a suit in the United States District Court of Utah claiming certain of our implantable port products infringe on patents held by them. Bard is seeking unspecified damages and other relief. The Court denied Bard’s motion for pre-trial consolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but has asked for supplemental briefing on the issue of whether to conduct a common Markman hearing. We filed petitions for reexamination in the US Patent and Trademark Office which seek to invalidate all three patents asserted in the litigation. Our petitions have been granted and 40 of 41 patent claims have been rejected. The case has been stayed pending final resolution of the PTO process. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

Cardinal Health v. Navilyst Medical, Inc.

On December 21, 2011, Cardinal Health Canada 204, Inc. (Cardinal Health) filed a demand for arbitration pursuant to the terms of the International Distributorship Agreement entered into as of November 1, 2008 between Navilyst and Cardinal Health. Cardinal Health claims that it is entitled to damages based on Navilyst’s decision to terminate the International Distributorship Agreement. The parties have entered into a written stipulation to stay the proceedings in this matter pending the outcome of a related litigation brought by Cardinal health against three our current employees (all of whom are former employees of Cardinal Health) in the Ontario Superior Court of Justice (Cardinal Health Canada, Inc. vs. Alexander, Sohi & Campbell, Superior Court of Justice, Ontario, Canada, No. CV-11-440418 (the Ontario Litigation). If this matter proceeds following the stay, we intend to deny the allegations contained in the demand for arbitration and to advance counterclaims against Cardinal Health. Navilyst entered into a joint defense agreement with the defendants in the Ontario Litigation, pursuant to which Navilyst agreed, subject to certain conditions, to indemnify the defendants for all legal fees relating to the Ontario Litigation as well as any damages or cost awards arising out of the Ontario Litigation. While we intend to vigorously defend against these actions, each of these cases is in the preliminary states and, as result, the ultimate outcome of these cases and their potential financial impact are not determinable at this time.

Cirrex Systems LLC v. AngioDynamics, Inc.

On May 21, 2012, Cirrex Systems LLC filed a suit in the United States District Court of Georgia claiming that certain of our endovenous ablation products infringe a patent held by them. Cirrex was seeking unspecified damages and other relief. On October 3, 2012, we filed an answer denying infringement, asserting various affirmative defenses, and asserting counterclaims for a declaratory judgment of non-infringement and invalidity. On December 7, 2012, Cirrex voluntarily dismissed the suit.

Joseph Pierre v. AngioDynamics, Inc.

In July 2011, a former employee dual-filed a complaint with the New York State Division of Human Rights and the Equal Employment Opportunity Commission, entitled Joseph Pierre v. AngioDynamics, Inc. In this action, the former employee is alleging discrimination due to his status as an African-American, in light of him being reassigned to another project. At the conclusion of its investigation, the Division issued a finding of “no probable cause” on January 6, 2012 and dismissed the complaint. The complainant did not appeal the decision to preserve his New York Human Rights Law claims. On February 22, 2012, the Equal Employment Opportunity Commission issued its determination adopting the decision of the Division and dismissing the charge. The complainant filed a federal claim following the EEOC’s decision in the United States District Court for the Northern District of New York on May 21, 2012. This complaint makes the same allegations of discrimination, and alleges causes of action under Title VII of the Civil Rights Act and 42 U.S.C. 1981. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

We are party to other legal actions that arise in the ordinary course of business. We believe that any liability resulting from any currently pending litigation will not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations, or cash flows.

NOTE M – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 2011 and December 2011, the FASB updated the disclosure requirements for comprehensive income. The updated guidance requires companies to disclose 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. The updated guidance does not affect how earnings per share is calculated or presented. The updated guidance is effective annual periods, and interim periods within those years, beginning after December 15, 2011 (our fiscal year 2013). We have provided the disclosure in a separate statement herein. The adoption of this guidance had no material impact on our consolidated financial statements.

In September 2011, the FASB updated the accounting guidance related to testing goodwill for impairment. This update permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that a reporting unit’s fair value is more likely than not greater than its carrying value, the quantitative assessment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. This update is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011 (our fiscal year 2013) however, early adoption is permitted.

In July 2012, the FASB updated the accounting guidance related to testing indefinite-lived intangible assets for impairment. This update permits an entity to first make a qualitative assessment of whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired. The more-likely-than- not threshold is defined as having a likelihood of more than 50%. This update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012 (our fiscal year 2014) however early adoption is permitted, provided that the entity has not yet performed its annual impairment test or issued its financial statements. We are currently evaluating the impact of adoption of this accounting guidance on our consolidated financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read together with the consolidated financial statements and the notes thereto and other information included elsewhere in this quarterly report on Form 10-Q.

Forward-Looking Statements

This quarterly report on Form 10-Q, including the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements regarding AngioDynamics’ expected future financial position, results of operations, cash flows, business strategy, budgets, projected costs, capital expenditures, products, competitive positions, growth opportunities, plans and objectives of management for future operations, as well as statements that include the words such as “expects,” “reaffirms” “intends,” “anticipates,” “plans,” “believes,” “seeks,” “estimates,” or variations of such words and similar expressions, are forward-looking statements.

Other risks and uncertainties include, but are not limited to, the factors described from time to time in our reports filed with the SEC, including our Form 10-K for the fiscal year ended May 31, 2012.

Although we believe that the assumptions underlying the forward-looking statements contained herein are reasonable, any of the assumptions could be inaccurate and, therefore, there can be no assurance that the forward-looking statements included in this quarterly report on Form 10-Q will prove to be accurate.

Overview

We design, manufacture and sell a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. Our devices are generally used in minimally invasive, image-guided procedures. Most of our products are intended to be used once and then discarded, or they may be temporarily implanted for short- or long-term use.

We sell our products in the United States through a direct sales force and outside the U.S. through a combination of direct sales and distributor relationships. For the three and six months ended November 30, 2012, approximately 20% and 19% of our net sales were from markets outside the United States compared with 15% and 14% in the three and six months ended November 30, 2011.

Our growth depends, in part, on the introduction of new and innovative products, together with ongoing enhancements to our existing products, through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to make investments in, research and development. For the three and six months ended November 30, 2012, our research and development (“R&D”) expenditures were $7.0 million and $14.1 million, which represented 8% of net sales for both periods. Comparable prior year expenditures were $5.1 million, or 9% of net sales for the quarter and $10.7 million or 10% of net sales for the year to date period. We expect to continue to spend considerable amounts on R&D activities in the future; however, downturns in our business could cause us to reduce our R&D spending.

Except to the extent we can further use our cash and short term investments or our equity securities as acquisition capital, we will require additional equity or debt financing to fund any future significant acquisitions.

Our ability to further increase our profitability will depend in part on improving gross profit margins. Factors such as changes in our product mix, new technologies and price pressures may cause our margins to grow at a slower rate than we have anticipated, or to decline. We are currently operating our manufacturing facilities at less than full capacity.

Recent Developments

See Note A to our consolidated financial statements in this Quarterly Report on Form 10-Q for recent developments.

New Accounting Pronouncements

Information regarding new accounting pronouncements is included in Note M to our consolidated financial statements in this Quarterly Report on Form 10-Q.

Medical Device Excise Tax

A Medical Device Excise Tax (MDET) was enacted into law as part of the Health Care Education Reconciliation Act of 2010 and imposes an excise tax on medical device manufacturers on their sales in the U.S of certain devices after December 31, 2012. The tax is 2.3% of the taxable base which is generally defined as 75% of the selling price of the taxable product. We estimate approximately 60-65% of our worldwide sales will be subject to the MDET beginning on January 1, 2013.

Results of Operations

Three Months ended November 30, 2012 and November 30, 2011

For the second quarter of fiscal 2013, we reported net income of $2.0 million, or $0.06 per share, on net sales of $87.0 million, compared with net income of $2.3 million, or $0.09 per share, on net sales of $58.1 million in the second quarter of the prior year.

The following table sets forth certain operating data as a percentage of net sales:

	Three Months Ended
	Nov 30, 2012			Nov 30, 2011
Net sales		100.0	%		100.0	%
Gross profit		50.7	%		57.2	%
Research and development		8.1	%		8.8	%
Sales and marketing		21.5	%		27.3	%
General and administrative		7.9	%		8.0	%
Amortization of intangibles		4.7	%		4.0	%
Acquisition, restructuring and other items, net		2.6	%		2.4	%
Operating income		5.9	%		6.8	%
Other income(expenses)		(2.3	%)		(0.6	%)
Income taxes		1.3	%		2.1	%
Net income		2.3	%		4.0	%

Net sales. Net sales are derived from the sale of our products and related freight charges, less discounts and returns. Net sales of $87.0 million increased $28.9 million from the $58.1 million reported in the second quarter of fiscal 2012. This increase was primarily attributable to sales of products acquired in the Navilyst acquisition, microwave product sales from the Microsulis strategic relationship and increased EVLT product sales, partially offset by the absence of LC Beads sales following the end of distribution rights on December 31, 2011. Sales of LC Beads were $9.1 million in the second quarter of fiscal 2012.

From a product line perspective, Peripheral Vascular sales increased $22.7 million or 98% from the prior year period to $45.8 million. This increase was primarily attributable to sales of Navilyst fluid management products and increased EVLT product sales. Vascular Access sales were $26.7 million, an increase of $11.5 million from the prior year period. This increase is attributable to sales of Navilyst PICCs and port products. Oncology/Surgery sales were $12.0 million, a decrease of 39% from prior year sales of $19.8 million, primarily due to the decrease in LC Beads sales described earlier. Nanoknife sales totaled $3.3 million in the second quarter of fiscal 2013 and fiscal 2012.

From a geographic perspective, U.S. sales increased $20.0 million or 40% in the second quarter of fiscal 2013 to $69.7 million from $49.7 million a year ago. The increase in net sales was primarily attributable to sales of Navilyst products, increased EVLT product sales and increased Nanoknife product sales, partially offset by the $9.1 million decline in sales of LC Beads, described earlier. International sales were $17.4 million in the fiscal second quarter of 2013, an increase of 105% from $8.4 million in the comparable prior year period. The increase is attributable to sales of Navilyst products and microwave product sales from the Microsulis strategic relationship.

27

Gross profit. Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties and sold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead. Our gross profit as a percentage of sales decreased to 50.7% in the second quarter of 2013 from 57.2% a year ago. The decrease in gross profit is primarily attributable to the inclusion of the products acquired from Navilyst.

Research and development expenses. Research and development (“R&D”) expenses include costs to develop new products, enhance existing products, validate new and enhanced products, manage clinical, regulatory and medical affairs and our intellectual property. R&D expenses increased by $1.9 million, or 37%, to $7.0 million in the second quarter of fiscal 2013 compared to the same prior year period. The increase is primarily due to increased R&D personnel and project costs following the Navilyst acquisition. As a percentage of net sales, R&D expenses declined to 8.1% for the fiscal second quarter of 2013, from 8.8% for the same prior year period.

Sales and marketing expenses. Sales and marketing (“S&M”) expenses consist primarily of salaries, commissions, travel and related business expenses, attendance at medical society meetings, product promotions and marketing activities. S&M expenses increased $2.8 million or 18% to $18.7 million in the second quarter of fiscal 2013 from a year ago, with the increase primarily attributable to the addition of Navilyst sales and marketing personnel. As a percentage of net sales, S&M expenses declined to 21.5% in the fiscal second quarter of 2013, from 27.3% for the same prior year period.

General and administrative expenses. General and administrative (“G&A”) expenses include executive management, finance and accounting, information technology, human resources, business development, legal, and the administrative and professional costs associated with those activities. G&A expenses increased $2.3 million, or 49%, to $6.9 million in the second quarter of fiscal 2013 compared to the prior year period, primarily due to the addition of Navilyst personnel. G&A expenses decreased to 7.9% of net from 8.0% in the prior year period.

Amortization of intangibles. Amortization of intangibles was $4.1 million in the second quarter of fiscal 2013, an increase of $1.8 million from the second fiscal quarter of 2012, with the increase primarily related to amortization of intangibles acquired in the Navilyst acquisition.

Acquisition, restructuring and other items, net. The second quarter of fiscal 2013 included Acquisition, restructuring and other items, net expenses of $2.3 million which primarily consisted of $1.7 million of transaction and severance expenses related to the acquisition of Navilyst, $325 thousand of transaction costs related to the acquisition of Vortex, $425 thousand of litigation costs and approximately $279 thousand for expenses related to the closure of our manufacturing facility in the UK, partially offset by the $770 thousand net gain on the sale of our PDT laser product line. The prior year second quarter expense of $1.4 million was primarily comprised of $636 thousand of CEO and executive transition costs and $587 thousand of expenses related to the closure of our manufacturing facility in the UK.

Operating income. The second fiscal quarter of 2013 resulted in operating income of $5.1 million compared to $3.9 million for the second quarter of fiscal 2012. As a percentage of sales, operating income was 5.9% for the second quarter of 2013 compared to 6.8% in the same prior year period.

Other income (expenses). Other income and expenses for the second quarter of fiscal 2013 was $2.0 million of net expense compared with $357 thousand of net expense in the same period a year ago, representing (2.3)% and (0.6)% of net sales in the respective periods. Interest on the debt incurred to finance the Navilyst acquisition is the primary cause of the increase.

Income taxes. Our effective tax rate was 37% for the second fiscal quarter of 2013 compared with 35% expense for the prior year period. The current quarter is affected by a reduction in the Domestic Production Activities Deduction caused by reduced taxable income, the tax impact of non-deductible costs related to the acquisition of Vortex and a tax benefit related to the use of fully reserved capital loss carryforwards made possible by the gain on sale of our PDT laser product line. The prior year quarter reflects a benefit from the R&D tax credit which expired December 31, 2011.

Net income. For the second quarter of 2013, we reported net income of $2.0 million, a decrease of $360 thousand from net income of $2.3 million for the prior year quarter.

28

Six Months ended November 30, 2012 and November 30, 2011

For the first six months of fiscal 2013, we reported net income of $1.2 million, or $0.04 per share, on net sales of $170.4 million, compared with net income of $3.7 million, or $0.15 per share, on net sales of $112.5 million in the first six months of the prior year.

The following table sets forth certain operating data as a percentage of net sales:

	Six Months Ended
	Nov 30, 2012			Nov 30, 2011
Net sales		100.0	%		100.0	%
Gross profit		49.0	%		58.1	%
Research and development		8.3	%		9.5	%
Sales and marketing		21.8	%		28.6	%
General and administrative		8.1	%		7.9	%
Amortization of intangibles		4.6	%		4.1	%
Acquisition, restructuring and other items, net		2.8	%		2.1	%
Operating income		3.4	%		5.9	%
Other income(expenses)		(2.2	%)		(0.9	%)
Income taxes		0.4	%		1.8	%
Net income		0.7	%		3.3	%

Net sales. Net sales of $170.4 million increased $57.9 million from the $112.5 million reported in the first six months of fiscal 2012. The increase was primarily attributable to sales of products acquired in the Navilyst acquisition, microwave product sales from the Microsulis strategic relationship and increased EVLT product sales, partially offset by the absence of LC Beads sales following the end of distribution rights on December 31, 2011. Sales of LC Beads were $17.1 million in the first six months of fiscal 2012.

From a product line perspective, Peripheral Vascular sales increased $45.0 million or 102% from the prior year period to $89.1 million. This increase was primarily attributable to sales of Navilyst fluid management products and increased EVLT product sales. Vascular Access sales were $53.3 million, an increase of $22.5 million from the prior year period. This increase is attributable to sales of Navilyst PICCs and port products. Oncology/Surgery sales were $23.2 million, a decrease of 38% from prior year sales of $37.7 million, primarily due to the decrease in LC Beads sales previously described. Nanoknife sales totaled $6.4 million in the first six months of fiscal 2013 and $5.5 million in the prior year period.

From a geographic perspective, U.S. sales increased $40.7 million or 42% in the first six months of fiscal 2013 to $137.7 million from $97.0 million a year ago. This increase was primarily attributable to sales of Navilyst products, increased EVLT product sales and increased Nanoknife product sales, partially offset by the $17.1 million decline in sales of LC Beads, described earlier. International sales were $32.7 million in the first six months of fiscal 2013, an increase of 110% from $15.6 million in the comparable prior year period. The increase is attributable to sales of Navilyst products and microwave product sales from the Microsulis strategic relationship.

Gross profit. Our gross profit as a percentage of sales decreased to 49.0% in the first six months of fiscal 2013 from 58.1% in the same period a year ago. The decrease in gross profit is primarily attributable to the inclusion of the products acquired from Navilyst. In addition, the gross profit was reduced by the $3.4 million amortization of the step-up in basis of the acquired Navilyst inventory and $793 thousand of expenses for our Quality Call To Action program to review and augment our Quality Management Systems.

Research and development expenses. R&D expenses increased by $3.4 million, or 31%, to $14.1 million in the first six months of fiscal 2013 compared to the same prior year period. The increase is primarily due to increased R&D personnel and project costs following the Navilyst acquisition. As a percentage of net sales, R&D expenses declined to 8.3% for the fiscal first six months of 2013 from 9.5% for the same period a year ago.

Sales and marketing expenses. S&M expenses increased $5.1 million or 16% to $37.2 million in the first six months of fiscal 2013 from a year ago with the increase primarily attributable to the addition of Navilyst sales and marketing personnel. As a percentage of net sales, S&M expenses declined to 21.8% for the fiscal first six months of 2013, from 28.6% for the same period a year ago.

29

General and administrative expenses. G&A expenses increased $4.9 million, or 55%, to $13.8 million in the first six months of fiscal 2013 compared to the prior year period, primarily due to the addition of Navilyst personnel. G&A expenses increased to 8.1% of net sales from 7.9% in the prior year period.

Amortization of intangibles. Amortization of intangibles was $7.8 million in the 2013 fiscal first six months, an increase of $3.3 million from the prior year period with the increase primarily related to amortization of intangibles acquired in the Navilyst acquisition.

Acquisition, restructuring and other items, net. The first six months of fiscal 2013 included Acquisition, restructuring and other items, net expenses of $4.8 million which primarily consisted of $3.9 million of transaction and severance costs related to the acquisition of Navilyst, $616 thousand for expenses related to the closure of our manufacturing facility in the UK, $325 thousand of transaction costs related to the acquisition of Vortex, $425 thousand of litigation costs, partially offset by the $770 thousand net gain on the sale of our PDT laser product line. The prior year period expense of $2.3 million was primarily comprised of $1.7 million of CEO and executive transition costs and $883 thousand of expenses related to the closure of our manufacturing facility in the UK.

Operating income. The first six months of fiscal 2013 resulted in operating income of $5.8 million compared to $6.6 million for the same period of fiscal 2012. As a percentage of sales, operating income was 3.4% for the 2013 fiscal first six months compared to 5.9% in the same prior year period.

Other income (expenses). Other income and expenses for the first six months of fiscal 2013 was $3.8 million of net expense compared with $1.0 million net expense in the same period a year ago, representing (2.2)% and (0.9)% of net sales in the respective periods. Interest on the debt incurred to finance the Navilyst acquisition is the primary cause of the increase.

Income taxes. Our effective tax rate was 37% for the first six months of fiscal 2013 compared with 35% expense for the prior year period. The current period is affected by a reduction in the Domestic Production Activities Deduction caused by reduced taxable income, the tax impact of non-deductible costs related to the acquisition of Vortex and a tax benefit related to the use of fully reserved capital loss carryforwards made possible by the gain on sale of our PDT laser product line. The prior year period reflects a benefit from the R&D tax credit which expired December 31, 2011.

Net income. For the first six months of fiscal 2013, we reported net income of $1.2 million, a decrease of $2.5 million from net income of $3.7 million for the prior year period.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities totaled $24.0 million at November 30, 2012 compared with $40.1 million at May 31, 2012. Marketable securities consist of U.S. government issued or guaranteed securities, corporate bonds and auction rate securities. At November 30, 2012, total debt was $146.3 million primarily comprised of short and long-term bank debt that financed our acquisition of Navilyst in May 2012. In accounting for the Vortex acquisition, the fair value of contingent milestone payments was remeasured as of November 30, 2012. As a result, $52.4 million was reflected in “Contingent consideration, net of current portion” and $8.1 million was reflected in “Current portion of contingent consideration” on the condensed consolidated balance sheet.

Effect of exchange rate changes on cash and cash equivalents		12			(18	)
Net change in cash and cash equivalents	$	(4,186	)	$	(3,029	)

Net cash provided by operating activities in the first half of fiscal 2013 was $5.5 million compared with $5.7 million a year ago. Cash provided by operating activities during the first six months of fiscal year 2013 was primarily the result of non-cash expense items, such as amortization, depreciation and stock-based compensation, and the utilization of tax loss carryforwards and other tax attributes gained through acquisitions, partially offset by increased inventories and other changes in working capital balances. The prior year period consisted of similar components with higher net income, lower depreciation and amortization and lower net changes in working capital balances.

Net cash used in investing activities was $6.4 million for the six months ended November 30, 2012, compared with $8.7 million for the same prior year period. The net cash used in investing activities for the current year period consisted primarily of the Vortex acquisition offset by net proceeds from the sale of marketable securities and the sale of our PDT laser product line. The prior year period use of cash consisted primarily of net purchases of marketable securities.

Net cash used in financing activities was $3.3 million for the six months ended November 30, 2012 compared to net cash provided by financing activities of $11 thousand for the comparable prior year period. The current year period consisted primarily of repayment of long-term debt while the prior year period benefitted from increased exercise of stock options, partially offset by the repurchase and retirement of shares.

Our contractual obligations and their effect on liquidity and cash flows have not changed substantially from that disclosed in our Annual Report on Form 10-K for our fiscal year ended May 31, 2012.

We believe that our current cash and investment balances, together with cash generated from operations and our $50 million revolving credit facility, will provide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. If we seek to make significant acquisitions of other businesses or technologies in the future for cash, we may require external financing.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk due to changes in interest rates. To reduce this risk, we periodically enter into certain derivative financial instruments to hedge the underlying economic exposure. We use derivative instruments as part of our interest rate risk management strategy.

In June 2012, we entered into an interest rate swap agreement, with an initial notional amount of $100 million, to limit the effect of variability due to interest rates on the loan. The Swap Agreement, which qualifies for hedge accounting under authoritative guidance, is a contract to exchange floating interest rate payments for fixed interest rate payments on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement.

We sell our products in currencies other than US dollars, primarily the Euro, GB pound and Canadian dollar. Approximately 6% of our sales in the first six months of fiscal 2013 were denominated in currencies other than the US dollar. We currently have no significant direct foreign currency exchange risk.

Our excess cash is invested in highly liquid, short-term, investment grade securities with maturities primarily of less than two years. These investments are not held for speculative or trading purposes. Changes in interest rates may affect the investment income we earn on cash, cash equivalents and marketable securities and therefore affect our cash flows and results of operations. We hold investments in auction rate securities (“ARS”) in order to generate higher than typical money market investment returns. ARS typically are high credit quality instruments, generally achieved with municipal bond insurance. Credit risks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids. Such instances are usually the result of a drastic deterioration of issuer credit quality. Should there be a failed auction, we may be unable to liquidate our position in the securities in the near term. We have $1.85 million in investments in two auction rate securities issued by New York state and local government authorities that have failed auctions. The authorities are current in their interest payments on the securities.

We are party to legal actions that arise in the ordinary course of business as described in Note L.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are functioning effectively to provide reasonable assurance that the information required to be disclosed by us (including our consolidated subsidiaries) in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting in the fiscal quarter ended November 30, 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

AngioDynamics, Inc. and Subsidiaries

Part II: Other Information

Item 1. Legal Proceedings.

AngioDynamics v. biolitec

On January 2, 2008, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. biolitec, Inc. In this action, we are seeking judgment against biolitec for defense and indemnification in two lawsuits which we previously settled. Our claims arise out of a Supply and Distribution Agreement (“SDA”) entered into with biolitec on April 1, 2002. On September 27, 2011, the U.S. District Court for the Northern District of New York granted key portions of our motion for summary judgment in our legal case against biolitec. The Court’s order was filed under seal. The Court also dismissed biolitec’s counterclaims against us. The court denied one portion of our summary judgment motion, which sought to recover additional costs from biolitec, leaving this for adjudication at trial. On September 28, 2012, the Court granted partial judgment to us in the amount of $16.4 million, along with pre-judgment interest.

In October 2009, we commenced an action in the United States District Court for the District of Massachusetts entitled AngioDynamics, Inc. v. biolitec AG and Wolfgang Neuberger. The Complaint in this action was amended in March 2010. This action seeks to recover against biolitec, Inc.’s parent entities and CEO for tortiously interfering with biolitec, Inc.’s contractual obligation to defend and indemnify us, and also seeks to pierce the corporate veil of biolitec, Inc. and to invalidate certain alleged fraudulent transfers in order to hold biolitec, Inc.’s parent entities jointly and severally liable for the alleged breach of the SDA. This case is currently in the discovery phase. On September 13, 2012, the Massachusetts Court granted our request for a preliminary injunction prohibiting the downstream merger of biolitec AG with its Austrian subsidiary.

We will continue to vigorously enforce our rights under the supply agreement with biolitec.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. filed a suit in the United States District Court of Utah claiming certain of our implantable port products infringe on patents held by them. Bard is seeking unspecified damages and other relief. The Court denied Bard’s motion for pre-trial consolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but has asked for supplemental briefing on the issue of whether to conduct a common Markman hearing. We filed petitions for reexamination in the US Patent and Trademark Office which seek to invalidate all three patents asserted in the litigation. Our petitions have been granted and 40 of 41 patent claims have been rejected. The case has been stayed pending final resolution of the PTO process. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

Cardinal Health v. Navilyst Medical, Inc.

On December 21, 2011, Cardinal Health Canada 204, Inc. (Cardinal Health) filed a demand for arbitration pursuant to the terms of the International Distributorship Agreement entered into as of November 1, 2008 between Navilyst and Cardinal Health. Cardinal Health claims that it is entitled to damages based on Navilyst’s decision to terminate the International Distributorship Agreement. The parties have entered into a written stipulation to stay the proceedings in this matter pending the outcome of a related litigation brought by Cardinal health against three our current employees (all of whom are former employees of Cardinal Health) in the Ontario Superior Court of Justice (Cardinal Health Canada, Inc. vs. Alexander, Sohi & Campbell, Superior Court of Justice, Ontario, Canada, No. CV-11-440418 (the Ontario Litigation). If this matter proceeds following the stay, we intend to deny the allegations contained in the demand for arbitration and to advance counterclaims against Cardinal Health. Navilyst entered into a joint defense agreement with the defendants in the Ontario Litigation, pursuant to which Navilyst agreed, subject to certain conditions, to indemnify the defendants for all legal fees relating to the Ontario Litigation as well as any damages or cost awards arising out of the Ontario Litigation. While we intend to vigorously defend against these actions, each of these cases is in the preliminary states and, as result, the ultimate outcome of these cases and their potential financial impact are not determinable at this time.

Cirrex Systems LLC v. AngioDynamics, Inc.

On May 21, 2012, Cirrex Systems LLC filed a suit in the United States District Court of Georgia claiming that certain of our endovenous ablation products infringe a patent held by them. Cirrex was seeking unspecified damages and other relief. On October 3, 2012, we filed an answer denying infringement, asserting various affirmative defenses, and asserting counterclaims for a declaratory judgment of non-infringement and invalidity. On December 7, 2012, Cirrex voluntarily dismissed the suit.

33

Joseph Pierre v. AngioDynamics, Inc.

In July 2011, a former employee dual-filed a complaint with the New York State Division of Human Rights and the Equal Employment Opportunity Commission, entitled Joseph Pierre v. AngioDynamics, Inc. In this action, the former employee is alleging discrimination due to his status as an African-American, in light of him being reassigned to another project. At the conclusion of its investigation, the Division issued a finding of “no probable cause” on January 6, 2012 and dismissed the complaint. The complainant did not appeal the decision to preserve his New York Human Rights Law claims. On February 22, 2012, the Equal Employment Opportunity Commission issued its determination adopting the decision of the Division and dismissing the charge. The complainant filed a federal claim following the EEOC’s decision in the United States District Court for the Northern District of New York on May 21, 2012. This complaint makes the same allegations of discrimination, and alleges causes of action under Title VII of the Civil Rights Act and 42 U.S.C. 1981. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

We are party to other legal actions that arise in the ordinary course of business. We believe that any liability resulting from any currently pending litigation will not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations, or cash flows.

Acquisitions [Abstract]

ACQUISITIONS

NOTE B – ACQUISITIONS

Acquisition of Vortex Medical, Inc.

On October 15, 2012, we acquired all the outstanding capital stock of Vortex Medical, Inc., a privately-held company focused on the development and commercialization of medical devices for venous drainage and the removal of thrombus, or blood clots, from occluded blood vessels. Vortex’s principal product is the AngioVac ^® system, which includes the AngioVac Cannula and Circuit. The AngioVac Cannula has a proprietary balloon-actuated, expandable, funnel-shaped distal tip that enhances flow, prevents clogging of the cannula and facilitates en bloc, or whole removal of undesirable intravascular material. Both the AngioVac Cannula and Circuit are FDA-cleared for use during extracorporeal bypass for up to 6 hours. An application for CE Mark approval has been filed.

The stock purchase agreement provided for the payment of $15.1 million in cash at closing, which is subject to a working capital adjustment, plus future earn out consideration payable in cash. Earn out consideration is based on our net sales of the AngioVac system during the ten years following the closing, payable in the amount of 10% of annual net sales up to $150 million, 12.5% of annual net sales between $150 million and $500 million, and 15% of annual net sales above $500 million. The Earn out consideration is subject to guaranteed minimum payments payable on the anniversary dates following closing, in the amounts of $8.35 million on the first, $8.0 million on the second, third and fourth, and $7.65 million on the fifth anniversary date. If a minimum payment for a period exceeds the contingent earn out payment for the same period, the amount of the excess will be credited against future contingent earn out payments.

The total estimated purchase consideration of $75.4 million includes the upfront payment of $15.1 million and the estimated fair value of contingent consideration of $60.3 million. The estimated fair value of contingent consideration is based on projected AngioVac net sales in the ten year period following the closing. The amount of the Earn out consideration that could be paid on AngioVac net sales is not limited.

The Vortex historical financial results were not significant and therefore pro forma results would not be substantially different. Sales since the acquisition closed are negligible and the operations of Vortex have been fully integrated from the date of acquisition.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed (in thousands):

Cash and cash equivalents	$	339
Accounts receivable		200
Inventories		488
Other assets		6
Deferred tax assets		1,307
Intangibles		72,430
Goodwill		30,019
Total assets acquired		104,789
Deferred tax liabilities		(28,451	)
Liabilities assumed		(931	)
Total purchase price	$	75,407
Up front payment	$	15,105
Present value of contingent consideration liability		60,302
Total purchase price	$	75,407

The estimated purchase consideration exceeds the fair value of the acquired net assets by $30.0 million and was recorded as goodwill. Goodwill is not deductible for tax purposes. Core technologies are being amortized over their estimated useful lives of approximately 15 years as revenues are earned from the sales of the related products. We incurred acquisition related costs of $325 thousand, which were expensed to “Acquisition, restructuring and other items, net” in the statement of income. We have not finalized the purchase accounting, which may be adjusted as further information about conditions existing at the acquisition date becomes available.

Acquisition of Navilyst

On May, 22, 2012, we completed the acquisition of privately-held Navilyst, a global medical device company with strengths in the vascular access, interventional radiology and interventional cardiology markets. The acquisition and related transaction costs were financed through the issuance of approximately 9.5 million shares of our common stock, $150 million in drawn acquisition debt financing and $97 million of cash. Based on the closing price of our stock of $12.44 on the day prior to the transaction, the purchase price was approximately $361 million.

The three and six month periods ended November 30, 2012 include approximately $1.7 million and $3.9 million, respectively, in transaction and severance costs related to the Navilyst acquisition. These costs are included in “Acquisition, restructuring and other items, net” in the statement of income. Investment funds affiliated with Avista Capital Partners, former owners of Navilyst, received approximately 9.5 million shares of our common stock and, as of November 30, 2012, held approximately 27% of our outstanding shares. Investment funds affiliated with Avista Capital Partners entered into a stockholders agreement with us as part of the transaction and also appointed two additional directors to our existing Board of Directors.

To satisfy any working capital adjustment and potential indemnification claims that may arise, $19.1 million of purchase consideration has been placed in escrow, including approximately $14.0 million in cash and approximately 415 thousand shares of common stock, determined based on the closing price of $12.44 on the day prior to the transaction. The indemnification claims period will terminate on July 15, 2013. At May 31, 2012 and November 30, 2012, we had $2.5 million of receivable related to the working capital adjustment recorded as escrow receivable on the balance sheet.

Goodwill recorded as a result of the acquisition was $145.2 million. Intangible assets acquired, other than goodwill, totaled approximately $107.1 million, of which $49.4 million has been identified as customer relationships (15-year weighted average useful life), $32.5 million of trademarks (of which $28.6 million has been determined to have an indefinite useful life and the remaining $3.9 million has a 7 year weighted average useful life), $15.1 million of in-process research and development (indefinite useful life until completed) and $10.1 million of technology (6-year weighted average useful life).

The IPR&D assets, which were accounted for as indefinite-lived assets at the time of acquisition, represent the development of a biomedical polymer additive for use in PICC and other vascular access product lines and a power injectable port which are valued at $12.1 million and $3.0 million, respectively. The biomedical polymer additive product recently received regulatory approval and the product was released in the United States in October 2012 and is being amortized over a 10 year useful life. The power injectable port is expected to be released in the United States in fiscal 2013, subject to regulatory approvals. The fair value of these intangible assets was determined based upon the present value of expected future cash flows adjusted for the probability of technological and commercial risk, utilizing a risk-adjusted discount rate.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of the acquisition (in thousands):

	May 22, 2012
Cash and cash equivalents	$	7,683
Accounts receivable		19,069
Inventories		26,851
Prepaid expenses and other current assets		5,504
Property, plant and equipment		34,017
Deferred tax assets		33,709
Goodwill		145,221
Intangibles		107,100
Other long-term assets		497
Total assets acquired		379,651
Liabilties assumed		(18,287	)
Total net assets acquired	$	361,364

The purchase price allocation is subject to change as additional information becomes available concerning the fair value and tax basis of the acquired assets and liabilities. Any adjustment to the purchase price allocation will be made as soon as practicable but no later than one year from May 22, 2012, the acquisition date. See Note D for additional information about changes in the carrying amount of goodwill.

Investment in Microsulis Medical Ltd

On March 22, 2012, we established a strategic relationship with Microsulis Medical Ltd., a U.K.-based company specializing in minimally-invasive, microwave ablation technology for the coagulation of soft tissue.

The relationship includes a $5 million investment in Microsulis through the purchase of senior preferred stock, representing a 14.3% ownership position, exclusive distribution rights to market and sell their microwave ablation systems in all markets outside the United States from May 2012 through December 2013, and an exclusive option to purchase at any time until September 22, 2013, substantially all of the global assets of Microsulis Medical, Ltd. We have accounted for the investment under the cost method. The $5 million investment is included in intangible assets and other non-current assets on the balance sheet at November 30, 2012 and May 31, 2012.

Consolidated Financial Statements [Abstract]

CONSOLIDATED FINANCIAL STATEMENTS

NOTE A – CONSOLIDATED FINANCIAL STATEMENTS

The consolidated balance sheet as of November 30, 2012, the consolidated statement of stockholders’ equity and the consolidated statement of cash flows for the six months ended November 30, 2012 and the consolidated statements of income and the consolidated statements of comprehensive income for the three and six months ended November 30, 2012 and November 30, 2011 have been prepared by us without audit. The consolidated balance sheet as of May 31, 2012 was derived from audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments (which include only normally recurring adjustments) necessary to state fairly the financial position, changes in stockholders’ equity and comprehensive income, results of operations and cash flows as of and for the period ended November 30, 2012 (and for all periods presented) have been made.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. It is suggested that these unaudited interim consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended May 31, 2012, filed by us on August 14, 2012. Our most significant accounting policies are disclosed in Note A to the consolidated financial statements included in the aforementioned Form 10-K for the fiscal year ended May 31, 2012. The results of operations in the fiscal periods ended November 30, 2012 and November 30, 2011 are not necessarily indicative of the operating results for the respective full fiscal years.

The unaudited interim consolidated financial statements for the three and six months ended November 30, 2012 and November 30, 2011 include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, RITA Medical Systems, LLC, AngioDynamics UK Limited, AngioDynamics Netherlands B.V., NM Holding Company, Inc. (Navilyst) since May 22, 2012 and Vortex Medical, Inc. since October 15, 2012 (collectively, the “Company”). All intercompany balances and transactions have been eliminated.

Effective June 1, 2012, we consider our business to be a single segment entity – the development, manufacture and sale on a global basis of medical devices for vascular access, surgery, peripheral vascular disease and oncology. Our chief operating decision maker (CEO) evaluates the various global product portfolios on a net sales basis. Executives reporting in to the CEO include those responsible for operations and supply chain management, research and development, sales, franchise marketing and certain corporate functions. The CEO evaluates profitability, investment and cash flow metrics on a consolidated worldwide basis due to shared infrastructure and resources. Prior to fiscal year 2013, our business was organized as two segments: Vascular and Oncology/Surgery, each under the direction of a general manager with direct responsibility for all sales, marketing and product development activities.

We have performed an evaluation of subsequent events through the date the financial statements were issued.

Acquisition of Vortex Medical Inc.

On October 15, 2012, we acquired all the outstanding capital stock of Vortex Medical, Inc., a privately-held company focused on the development and commercialization of medical devices for venous drainage and the removal of thrombus, or blood clots, from occluded blood vessels. Vortex’s principal product is the AngioVac ^® system, which includes the AngioVac Cannula and Circuit. The AngioVac Cannula has a proprietary balloon-actuated, expandable, funnel-shaped distal tip that enhances flow, prevents clogging of the cannula and facilitates en bloc, or whole removal of undesirable intravascular material. Both the AngioVac Cannula and Circuit are FDA-cleared for use during extracorporeal bypass for up to 6 hours. An application for CE Mark approval has been filed.

The total estimated purchase consideration of $75.4 million includes an upfront payment of $15.1 million and the estimated fair value of contingent (Earn out) consideration of $60.3 million. The estimated fair value of contingent consideration is based on projected Angio Vac net sales in the ten year period following the closing. The amount of the Earn out consideration that could be paid on Angio Vac net sales is not limited.

The estimated purchase consideration exceeds the fair value of the acquired net assets by $30.0 million and was recorded as goodwill. Goodwill is not deductible for tax purposes. Core technologies are being amortized over their estimated useful lives of approximately 15 years as revenues are earned from the sales of related products. We incurred acquisition related costs of $325 thousand, which were expensed to “Acquisition, restructuring and other items, net” in the statement of income. We have not finalized the purchase accounting, which may be adjusted as further information about conditions existing at the acquisition date becomes available. See Note B for additional information.

Regulatory Matters

On May 27, 2011, we received a Warning Letter from FDA in connection with its inspection of our Queensbury, NY manufacturing facility. In the Warning Letter, FDA cited deficiencies in the response letter we provided FDA pertaining to the inspection that occurred from January 4 to January 13, 2011. The deficiencies related to our internal procedures for medical device reporting, corrections and removals and complaint handling. We responded to the Warning Letter and completed corrective and preventive actions to address the observations noted.

In December 2011, we initiated a comprehensive Quality Call to Action Program to review and augment our Quality Management Systems at our Queensbury facility. To accelerate implementation of the program, we engaged a team of external regulatory and quality experts and reallocated a significant number of engineering and product development resources to support this corporate initiative. From inception of the Quality Call to Action Program through the second fiscal quarter of 2013, we have incurred $3.1 million in direct costs associated with the program.

On February 10, 2012, we received from FDA a Form 483, List of Investigational Observations, in connection with its inspection of our Queensbury facility from November 14, 2011 to February 10, 2012. The Form 483 contained 12 observations related to, among other things, our CAPA (Corrective and Preventive Action) system, MDR (Medical Device Reporting), complaint investigation, corrections and removals, acceptance criteria and training. Some of the observations contained in the Form 483 were repeat observations from the May 27, 2011 Warning Letter.

On February 13, 2012, we received from FDA a Form 483 in connection with its inspection of our Fremont facility from January 12, 2012 to February 13, 2012. The Form 483 contained six observations related to, among other things, our CAPA system, design controls, risk management and training. We provided responses to FDA within 15 business days of our receipt of the Form 483s.

On September 24, 2012, we received from FDA a Form 483 in connection with its subsequent inspection of our Queensbury, NY facility from September 6 to September 14, and September 19 and September 24. This re-inspection followed our response to the original Form 483 issued by FDA on February 13, 2012. The Form 483 contained 5 observations related to 510(k) decisions, complaint investigations, acceptance criteria, corrective and preventive actions and training. All but one of the observations in the Form 483 related to events that occurred before the date that we had indicated to FDA in our previous responses that our corrective and remediation activities related to our Quality Call to Action would be completed. We provided responses to FDA within 15 business days of our receipt of the Form 483.

On November 28, 2012, FDA completed an inspection of our Manchester, GA facility and no Form 483 observations were issued.

We will continue to work closely with FDA to resolve any outstanding issues. Unless the items raised in the previously disclosed Warning Letters and Form 483s are corrected to FDA’s satisfaction or we come to some other arrangement with FDA finally resolving such matters, we may be subject to additional regulatory or legal action, including the issuance of warning letters, injunction, seizure or recall of products, imposition of fines or penalties or operating restrictions on our facilities. Such actions could significantly disrupt our ongoing business and operations and have a material adverse impact on our financial position and operating results.

In May 2011, we submitted to FDA an application for an Investigational Device Exemption for a clinical trial to study the use of NanoKnife in the treatment of pancreatic cancer. In June 2012, we submitted an amendment to our application to address matters raised by FDA in the course of their review of the application and to propose an expanded and enhanced controlled, randomized trial protocol. In August 2012, we received a disapproval letter from FDA requesting additional information and certain protocol changes. We intend to continue to work with FDA to address the matters raised in the August letter.

Expiration of our Distribution Agreement Amendment for LC Bead

The Supply and Distribution Agreement with Biocompatibles UK Limited, which granted us exclusive distribution rights to LC Beads in the United States, expired on December 31, 2011. LC Bead sales were $9.1 million and $17.1 million in the three and six months ending November 30, 2011, respectively.

Acquisition, restructuring and other items, net

Navilyst Acquisition Costs

The three and six month periods ended November 30, 2012 include approximately $1.7 million and $3.9 million, respectively, in transaction and severance costs related to the Navilyst acquisition. These costs are included in “Acquisition, restructuring and other items, net” in the statement of operations. See Note B for additional information.

Closure of UK facility

During the first fiscal quarter of 2012, we made the decision to close our Cambridge, UK facility and transfer the production of lasers to our Queensbury, NY facility. We subsequently extended the date for closing the UK facility and moving laser manufacturing from December 2011 to December 2012. We estimate the total cost of this project will be approximately $3.4 million. The income statements for the three month periods ending November 30, 2012 and November 30, 2011 include charges of $279 thousand and $587 thousand, respectively, for costs incurred associated with this closure. The income statements for the six month periods ending November 30, 2012 and November 30, 2011 include charges of $616 thousand and $883 thousand, respectively, for costs incurred associated with this closure. The charge is included in “Acquisition, restructuring and other items, net” in the income statement.

Fair Value [Abstract]

FAIR VALUE

NOTE J – FAIR VALUE

Our financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable, interest rate swap agreement and the contingent Earn out related to the acquisition of Vortex. The carrying amount of cash and cash equivalents, accounts receivable, marketable securities and accounts payable approximates fair value due to the immediate or short-term maturities. The interest rate swap agreement has been recorded at its fair value based on a valuation received from an independent third party. Marketable securities, with the exception of auction rate securities, are carried at their fair value as determined by quoted market prices. The contingent Earn out has been recorded at fair value using a discounted cash flow model.

Per our accounting policy, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This policy establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The policy describes three levels of inputs that may be used to measure fair value which are provided in the table below.

Level 1	Quoted prices in active markets for identical assets or liabilities. Level 1 assets include bank time deposits, money market funds, mutual funds and U.S. Treasury securities that are traded in an active exchange market.
Level 2	Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include US government securities and corporate bonds. When quoted market prices are unobservable, we obtain pricing information from an independent pricing vendor. The pricing vendor uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. Since many fixed income securities do not trade on a daily basis, the methodology of the pricing vendor uses available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The pricing vendor considers all available market observable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted prices, but rather determined from market observable information. These investments are included in Level 2 and primarily comprise our portfolio of corporate and government fixed income securities. Additionally included in Level 2 are interest rate swap agreements which are valued using a mid-market valuation model.
Level 3	Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category currently includes the auction rate securities where independent pricing information was not able to be obtained and the contingent Earn out related to the acquisition of Vortex. Our investments in auction-rate securities were classified as Level 3 as quoted prices were unavailable since these auction rate securities issued by New York state and local government authorities failed auction. Due to limited market information, we utilized a discounted cash flow (“DCF”) model to derive an estimate of fair value for all periods presented. The assumptions used in preparing the DCF model included estimates with respect to the amount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk associated with auction-rate securities. The contingent Earn out was valued utilizing a discounted cash flow method as detailed below.

The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis (in thousands):

Contingent Liability for Acquisition Earn Out

The total estimated purchase consideration related to the acquisition of Vortex Medical, Inc. included an estimated fair value of contingent or earn out consideration. The fair value of the contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within acquisition-related items in the condensed consolidated statements of earnings. We measure the initial liability and remeasure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements.

Contingent consideration liabilities will be remeasured to fair value each reporting period using projected net sales, discount rates, probabilities of payment and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected net sales are based on our internal projections and extensive analysis of the target market and the sales potential. Increases in projected net sales and probabilities of payment may result in higher fair value measurements in the future. Increases in discount rates and the projected time to payment may result in lower fair value measurements in the future. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in the future.

The recurring Level 3 fair value measurements of the contingent consideration liability include the following significant unobservable inputs ($ in millions):

	Fair value at Nov 30, 2012		Valuation Technique	Unobservable Input	Range
Net sales based payments	$	60.5	Discounted	Discount rate	4%
			cash flow	Probability of payment	75-100%
				Projected fiscal year of payment	2013 - 2022

At November 30, 2012, the estimated potential amount of undiscounted future contingent consideration that we expect to pay as a result of this acquisition is approximately $75 million. The milestones associated with the contingent consideration must be reached in future periods ranging from fiscal years 2013 to 2023 in order for the consideration to be paid.

The fair value of contingent milestone payments associated with the Vortex acquisition was remeasured as of November 30, 2012 and $52.4 million was reflected in “Contingent consideration, net of current portion” and $8.1 million was reflected in “Current portion of contingent consideration” on the condensed consolidated balance sheet. The following table provides a reconciliation of the beginning and ending balances of contingent milestone payments associated with the Vortex acquisition measured at fair value that used significant unobservable inputs (Level 3) (in thousands):

Beginning balance - May 31, 2012	$	—

Marketable Securities [Abstract]

MARKETABLE SECURITIES

NOTE K – MARKETABLE SECURITIES

Marketable securities, which are principally government agency bonds, auction rate investments and corporate commercial paper, are classified as “available-for-sale securities” in accordance with authoritative guidance issued by FASB and are reported at fair value, with unrealized gains and losses excluded from operations and reported as accumulated other comprehensive income (loss), net of the related tax effects, in stockholders’ equity. Cost is determined using the specific identification method. We hold investments in auction rate securities in order to generate higher than typical money market rate investment returns. Auction rate securities typically are high credit quality, generally achieved with municipal bond insurance. Credit risks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids and, in such cases, the auction fails and we may be unable to liquidate our position in the securities in the near term. As of November 30, 2012 and May 31, 2012, we had $1.85 million in investments in two auction rate securities issued by New York state and local government authorities that failed auctions. The authorities are current in their interest payments on the securities.

Goodwill and Intangible Assets [Abstract]

GOODWILL AND INTANGIBLE ASSETS

NOTE D – GOODWILL AND INTANGIBLE ASSETS

As previously discussed, effective June 1, 2012 we implemented a change to our internal reporting structure and we now view the business as one operating segment. In connection with this change, we have also re-assessed our reporting units in accordance with ASC 350 and have determined that, effective June 1, 2012 we have one reporting unit for goodwill impairment testing purpose. We have considered these internal structural changes and their potential impact as it relates to testing goodwill for impairment. We have assessed these changes from a qualitative perspective in determining whether it is more likely than not that the fair value of our single reporting unit is less than its carrying value as a basis for determining whether it is necessary for us to perform a two-step goodwill impairment test. Based on our qualitative assessment, we have determined that it is not more likely than not that the fair value of our reporting unit is less than its carrying value and therefore, goodwill is not impaired.

Changes in the carrying amount of goodwill for the six months ended November 30, 2012 are as follows (in thousands):

Balance, May 31, 2012	$	308,912
Adjustments to purchase price		(1,741	)
Goodwill acquired from Vortex		30,019
Balance, November 30, 2012	$	337,190

The above $1.7 million reduction in the carrying value of goodwill is the result of an $858,000 payment from Avista Capital Partners and an $883,000 increase in the value of deferred tax assets from the Navilyst acquisition.

The balances of intangible assets are as follows:

Litigation [Abstract]

LITIGATION

NOTE L – LITIGATION

AngioDynamics v. biolitec

On January 2, 2008, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. biolitec, Inc. In this action, we are seeking judgment against biolitec for defense and indemnification in two lawsuits which we previously settled. Our claims arise out of a Supply and Distribution Agreement (“SDA”) entered into with biolitec on April 1, 2002. On September 27, 2011, the U.S. District Court for the Northern District of New York granted key portions of our motion for summary judgment in our legal case against biolitec. The Court’s order was filed under seal. The Court also dismissed biolitec’s counterclaims against us. The court denied one portion of our summary judgment motion, which sought to recover additional costs from biolitec, leaving this for adjudication at trial. On September 28, 2012, the Court granted partial judgment to us in the amount of $16.4 million, along with pre-judgment interest.

In October 2009, we commenced an action in the United States District Court for the District of Massachusetts entitled AngioDynamics, Inc. v. biolitec AG and Wolfgang Neuberger. The Complaint in this action was amended in March 2010. This action seeks to recover against biolitec, Inc.’s parent entities and CEO for tortiously interfering with biolitec, Inc.’s contractual obligation to defend and indemnify us, and also seeks to pierce the corporate veil of biolitec, Inc. and to invalidate certain alleged fraudulent transfers in order to hold biolitec, Inc.’s parent entities jointly and severally liable for the alleged breach of the SDA. This case is currently in the discovery phase. On September 13, 2012, the Massachusetts Court granted our request for a preliminary injunction prohibiting the downstream merger of biolitec AG with its Austrian subsidiary.

We will continue to vigorously enforce our rights under the supply agreement with biolitec.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. filed a suit in the United States District Court of Utah claiming certain of our implantable port products infringe on patents held by them. Bard is seeking unspecified damages and other relief. The Court denied Bard’s motion for pre-trial consolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but has asked for supplemental briefing on the issue of whether to conduct a common Markman hearing. We filed petitions for reexamination in the US Patent and Trademark Office which seek to invalidate all three patents asserted in the litigation. Our petitions have been granted and 40 of 41 patent claims have been rejected. The case has been stayed pending final resolution of the PTO process. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

Cardinal Health v. Navilyst Medical, Inc.

On December 21, 2011, Cardinal Health Canada 204, Inc. (Cardinal Health) filed a demand for arbitration pursuant to the terms of the International Distributorship Agreement entered into as of November 1, 2008 between Navilyst and Cardinal Health. Cardinal Health claims that it is entitled to damages based on Navilyst’s decision to terminate the International Distributorship Agreement. The parties have entered into a written stipulation to stay the proceedings in this matter pending the outcome of a related litigation brought by Cardinal health against three our current employees (all of whom are former employees of Cardinal Health) in the Ontario Superior Court of Justice (Cardinal Health Canada, Inc. vs. Alexander, Sohi & Campbell, Superior Court of Justice, Ontario, Canada, No. CV-11-440418 (the Ontario Litigation). If this matter proceeds following the stay, we intend to deny the allegations contained in the demand for arbitration and to advance counterclaims against Cardinal Health. Navilyst entered into a joint defense agreement with the defendants in the Ontario Litigation, pursuant to which Navilyst agreed, subject to certain conditions, to indemnify the defendants for all legal fees relating to the Ontario Litigation as well as any damages or cost awards arising out of the Ontario Litigation. While we intend to vigorously defend against these actions, each of these cases is in the preliminary states and, as result, the ultimate outcome of these cases and their potential financial impact are not determinable at this time.

Cirrex Systems LLC v. AngioDynamics, Inc.

On May 21, 2012, Cirrex Systems LLC filed a suit in the United States District Court of Georgia claiming that certain of our endovenous ablation products infringe a patent held by them. Cirrex was seeking unspecified damages and other relief. On October 3, 2012, we filed an answer denying infringement, asserting various affirmative defenses, and asserting counterclaims for a declaratory judgment of non-infringement and invalidity. On December 7, 2012, Cirrex voluntarily dismissed the suit.

Joseph Pierre v. AngioDynamics, Inc.

In July 2011, a former employee dual-filed a complaint with the New York State Division of Human Rights and the Equal Employment Opportunity Commission, entitled Joseph Pierre v. AngioDynamics, Inc. In this action, the former employee is alleging discrimination due to his status as an African-American, in light of him being reassigned to another project. At the conclusion of its investigation, the Division issued a finding of “no probable cause” on January 6, 2012 and dismissed the complaint. The complainant did not appeal the decision to preserve his New York Human Rights Law claims. On February 22, 2012, the Equal Employment Opportunity Commission issued its determination adopting the decision of the Division and dismissing the charge. The complainant filed a federal claim following the EEOC’s decision in the United States District Court for the Northern District of New York on May 21, 2012. This complaint makes the same allegations of discrimination, and alleges causes of action under Title VII of the Civil Rights Act and 42 U.S.C. 1981. We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

We are party to other legal actions that arise in the ordinary course of business. We believe that any liability resulting from any currently pending litigation will not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations, or cash flows.

Earnings Per Common Share [Abstract]

EARNINGS PER COMMON SHARE

NOTE H – EARNINGS PER COMMON SHARE

Basic earnings per share are based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share further includes the dilutive effect of potential common stock consisting of stock options, warrants, and restricted stock units, provided that the inclusion of such securities is not antidilutive.

The following table sets forth the reconciliation of the weighted-average number of common shares (in thousands):

	Three Months Ended				Six Months Ended
	Nov 30, 2012		Nov 30, 2011		Nov 30, 2012		Nov 30, 2011

Effect of dilutive securities		484		150		514		171
Diluted		35,311		25,340		35,279		25,278

Excluded from the calculation of diluted earnings per common share were options and restricted stock awards issued to employees and non-employees to purchase 3.2 million and 3.0 million shares of common stock for the three and six months ended November 30, 2012, respectively, as their inclusion would be antidilutive. For the comparable three and six month period ended November 30, 2011, options and restricted stock awards issued to employees and non-employees to purchase 2.4 million and 2.1 million shares of common stock were also excluded as their inclusion would be antidilutive.

Long-Term Debt [Abstract]

LONG TERM DEBT

NOTE F – LONG TERM DEBT

Bank Credit Agreement

In connection with the Navilyst acquisition, we entered into a Credit Agreement with a group of banks which provided a $150 million senior secured term loan facility and a $50 million senior secured revolving credit facility. The $150 million in proceeds from the term loan were used to finance a portion of the consideration for the acquisition. The revolving facility may be used for general corporate purposes and was undrawn at November 30, 2012. Both facilities have five year maturities. The term facility has a quarterly repayment schedule equal to 5%, 5%, 15%, 25% and 50% of its principal amount in years one through five. The credit agreement contains certain financial covenants relating to fixed charge coverage and leverage, as defined, with which we were in compliance at November 30, 2012. Amounts borrowed under the Credit Agreement are collateralized by all our assets. Interest on both the term loan and the revolving loan is based on a base rate or Eurodollar rate plus an applicable margin with increases as our total leverage ratio increases, and with the base rate and Eurodollar rate have ranges of 1.0% to 1.75% and 2.0% to 2.75% respectively. In the event of default, the interest rate may be increased by 2.0%. The revolving facility will also carry a commitment fee of 0.30% to 0.50% per year on the unused portion. As of November 30, 2012, net deferred financing costs of $2.2 million are recorded as a component of other assets on the balance sheet and are being amortized over the remaining life of the related debt.

In June 2012, we entered in an interest rate swap agreement, with an initial notional amount of $100 million, to limit the effect of rising of interest rates. The Swap Agreement, which qualifies for hedge accounting under authoritative guidance, is a contract to exchange floating interest rate payments for fixed interest rate payments on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement.

Recently Issued Accounting Pronouncements [Abstract]

Comprehensive income

In June 2011 and December 2011, the FASB updated the disclosure requirements for comprehensive income. The updated guidance requires companies to disclose 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. The updated guidance does not affect how earnings per share is calculated or presented. The updated guidance is effective annual periods, and interim periods within those years, beginning after December 15, 2011 (our fiscal year 2013). We have provided the disclosure in a separate statement herein. The adoption of this guidance had no material impact on our consolidated financial statements.

Goodwill impairment

In September 2011, the FASB updated the accounting guidance related to testing goodwill for impairment. This update permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that a reporting unit’s fair value is more likely than not greater than its carrying value, the quantitative assessment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. This update is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011 (our fiscal year 2013) however, early adoption is permitted.

Indefinite-lived intangible assets impairment

In July 2012, the FASB updated the accounting guidance related to testing indefinite-lived intangible assets for impairment. This update permits an entity to first make a qualitative assessment of whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired. The more-likely-than- not threshold is defined as having a likelihood of more than 50%. This update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012 (our fiscal year 2014) however early adoption is permitted, provided that the entity has not yet performed its annual impairment test or issued its financial statements. We are currently evaluating the impact of adoption of this accounting guidance on our consolidated financial statements.

Recently Issued Accounting Pronouncements [Abstract]

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

NOTE M – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 2011 and December 2011, the FASB updated the disclosure requirements for comprehensive income. The updated guidance requires companies to disclose 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. The updated guidance does not affect how earnings per share is calculated or presented. The updated guidance is effective annual periods, and interim periods within those years, beginning after December 15, 2011 (our fiscal year 2013). We have provided the disclosure in a separate statement herein. The adoption of this guidance had no material impact on our consolidated financial statements.

In September 2011, the FASB updated the accounting guidance related to testing goodwill for impairment. This update permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that a reporting unit’s fair value is more likely than not greater than its carrying value, the quantitative assessment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. This update is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011 (our fiscal year 2013) however, early adoption is permitted.

In July 2012, the FASB updated the accounting guidance related to testing indefinite-lived intangible assets for impairment. This update permits an entity to first make a qualitative assessment of whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired. The more-likely-than- not threshold is defined as having a likelihood of more than 50%. This update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012 (our fiscal year 2014) however early adoption is permitted, provided that the entity has not yet performed its annual impairment test or issued its financial statements. We are currently evaluating the impact of adoption of this accounting guidance on our consolidated financial statements.
