NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   Description of Business

IRIS International, Inc. (the “Company”) was incorporated in California in 1979 and reincorporated in 1987 in Delaware. IRIS International, Inc. consists of three operating units. The Company’s in-vitro diagnostics segment also called Iris Diagnostics Division (“IDD”), designs, manufactures and markets systems, consumables and supplies for urinalysis and body fluids. The Sample Processing segment markets small centrifuges and other processing equipment and accessories for rapid specimen processing, as well as, equipment for fluorescent in-situ hybridization (FISH). The Personalized Medicine segment combines the research and development operations of the Company’s Iris Molecular Diagnostics and Arista Molecular, Inc. subsidiaries. Under this new segment we consolidate all operations for the development and commercialization of cancer diagnostic testing services and related products.

2.   Interim Financial Reporting

Basis of Presentation — The financial statements have been prepared in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended, and do not include all of the information and note disclosures required by accounting principles generally accepted in the United States (“GAAP”). These financial statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

The Consolidated Financial Statements included herein are unaudited, but in the opinion of management, such financial statements include all adjustments, including normal recurring adjustments, necessary to summarize fairly the Company’s financial position and results of operations for the interim periods. The results reported in these Consolidated Financial Statements for the interim periods should not be taken as indicative of results that may be expected for the entire year.

Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The significant estimates in the preparation of the consolidated financial statements relate to the assessment of the carrying allowance for doubtful accounts, inventory reserves, the useful lives, fair value and recoverability of carrying value of long-lived and intangible assets, including goodwill, unearned income on sales-type leases, estimated provisions for warranty costs, laboratory information system implementations, contingent consideration and deferred tax assets. Actual results and outcomes may differ from management’s estimates and assumptions.

Earnings Per Share — The Company computes and presents earnings per share in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 260, Earnings per share. Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants using the average market prices during the period. The weighted average number of outstanding antidilutive common stock options excluded from the computation of diluted net income per common share for the three and six months ended June 30, 2011 were 2,636,703 and 2,465,746, respectively. The weighted average number of outstanding antidilutive common stock options excluded from the computation of diluted net income per common share for the three and six months

ended June 30, 2010 was 1,830,000 in both periods. A reconciliation of the shares used in the calculation of basic and diluted earnings per common share is as follows:

Weighted average common shares outstanding — diluted		17,764		18,094		17,829		18,079

Foreign Currency Hedge — The Company conducts business in certain foreign markets, primarily in the European Union and Asia. To mitigate the potential impact of adverse fluctuations in the U.S. Dollar exchange rate for these currencies, the Company may periodically purchase foreign currency forward contracts. The Company does not speculate in these hedging instruments in order to profit from foreign currency exchanges nor does the Company enter into trades for which there are no underlying exposures.

Under FASB ASC Topic 815, Accounting for Derivative Instruments and Hedging Activities, the Company documents all relationships between hedging instruments and hedged items, as well as its risk management objective for undertaking these hedging transactions. This process includes relating the forward contracts that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedged items.

At June 30, 2011 and 2010, the Company did not have any foreign currency forward contracts.

Goodwill and Intangible Assets — Goodwill represents the excess of the aggregate purchase price over the fair value of the tangible and identifiable intangible assets acquired by the Company. Goodwill and intangible assets with indefinite lives, which consists of a CLIA license, are not amortized. Goodwill and intangible assets with indefinite lives are subject to impairment tests on an annual basis or more frequently if facts and circumstances warrant such a review. Goodwill and intangible assets with indefinite lives are evaluated in accordance with FASB ASC Topic 350, Intangibles-Goodwill and Other (“ASC 350”), based on various analyses, including a comparison of the carrying value of the reporting unit to its estimated fair value and discounted cash flows. The analysis necessarily involves significant management judgment to evaluate the capacity of an acquired business to perform within projections. If the carrying amount of a reporting unit exceeds its fair value, the goodwill impairment test is performed to measure the amount of the impairment loss, if any. During the six months ended June 30, 2011 and 2010, the Company did not record any impairment charges related to goodwill or intangible assets with indefinite lives.

Intangible assets are initially measured at their fair value, determined either by the fair value of the consideration exchanged for the intangible asset, or the estimated discounted cash flows expected to be generated from the intangible asset. Intangible assets with a finite life, such as core technology, customer relationships and non-compete agreements are amortized on a straight-line basis over their estimated useful life, ranging from 3 to 20 years. Intangible assets with a finite life are evaluated for impairment using the methodology set forth in FASB ASC Topic 360, Property, Plant and Equipment. Recoverability of these assets is assessed only when events have occurred that may give rise to a potential impairment. When a potential impairment has been identified, forecasted undiscounted net cash flows of the operations to which the asset relates are compared to the current carrying value of the long-lived assets present in that operation. If such cash flows are less than such carrying amounts, long-lived

IRIS INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

assets, including such intangibles, are written down to their respective fair values. During the six months ended June 30, 2011 and 2010, no intangible asset impairment was recorded.

In determining the useful lives of intangible assets, the Company considers the expected use of the assets and the effects of obsolescence, demand, competition, anticipated technological advances, market influences and other economic factors. For technology based intangible assets, the Company considers the expected life cycles of products which incorporate the corresponding technology.

Goodwill decreased $46,000 during the six months ended June 30, 2011 due to a return of purchase price from the seller of AlliedPath, Inc. (now Arista Molecular, Inc.) as a result of a settlement of claims made against funds escrowed as security for representations and warranties pursuant to the merger agreement, dated July 26, 2010. All of the goodwill balance relates to the Personalized Medicine segment.

Foreign Currency Exchange Translation — The functional currencies of the Company’s foreign subsidiaries are primarily accounted for in their respective local currencies. The statements of operations of foreign operations are translated into U.S. dollars at rates of exchange in effect each month. The balance sheets of these subsidiaries are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in stockholders’ equity as other comprehensive income (loss). Foreign currency transaction gains and losses from certain intercompany transactions are recorded in foreign currency transaction gain (loss) in other income (expense). Transactions denominated in currencies other than the functional currency are recorded based on rates in effect at the time such transactions arise. Subsequent changes in exchange rates result in transaction gains and losses and are reflected in the accompanying consolidated statements of operations as unrealized (based on the applicable period-end exchange rate) or realized based upon settlement of the transactions. All other foreign currency gains and losses are also recorded in foreign currency transaction gain (loss) and other. The Company recognized net foreign currency transaction gain of $28,000 and $414,000 for the three and six months ended June 30, 2011. The Company recognized net foreign currency transaction losses of $589,000 and $692,000 for the three and six months ended June 30, 2010. Such gains and losses were primarily attributable to volatility in the Euro and British Pound.

Foreign currency exchange gains (losses) related to intercompany balances were recorded in the Company’s statements of operations through June 30, 2011 as they represented short-term intercompany trade payables and receivables. On March 31, 2011, a substantial portion of the Company’s intercompany balances from its European subsidiaries were converted to promissory notes that are of a long-term investment nature (settlement of these notes is not planned or anticipated in the foreseeable future). As a result, foreign exchange gains and losses attributable to these promissory notes are recorded in stockholders’ equity as other comprehensive income (loss) beginning April 1, 2011.

Reclassifications — The Company reclassified amounts in segment and geographic information in prior periods to add the new operating segment, Personalized Medicine (which is further described in the Segments and Geographic footnote), to conform to the presentation used in the current period. The Personalized Medicine composition includes the research and development operations of Iris Molecular Diagnostics which had been included with the IDD segment in prior periods. These reclassifications had no impact on the Company’s previously reported income from operations, net income or basic or diluted earnings per share.

Certain Risks and Uncertainties — Financial instruments, which potentially expose the Company to concentration of credit risk, consist primarily of cash and cash equivalents, accounts receivable and investment in sales-type leases. Concentration of credit risk with respect to accounts receivable and investment in sales-type leases is mitigated by the Company’s performance of on-going credit evaluations of its customers and the Company maintains an allowance for doubtful accounts. Investments in sales-type leases are secured by the underlying instruments.

At June 30, 2011, the amount of the Company’s cash deposited in demand deposit accounts which are fully guaranteed by the Federal Deposit Insurance Corporation was $10.1 million. The rest of the cash balances on

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

deposit with banks are guaranteed by the Federal Deposit Insurance Corporation up to $250,000. The Company may be exposed to risk for the amount of funds held in one bank in excess of the insurance limit. In assessing the risk, the Company’s policy is to maintain cash balances with high quality financial institutions.

The Company derives most of its revenues from the sale of the urinalysis analyzers, and related supplies and services. Relatively modest declines in unit sales or gross margins could have a material adverse effect on the Company’s revenues and profits, respectively.

Certain of the Company’s components are obtained from outside vendors, and the loss or breakdown of the Company’s relationships with these outside vendors could subject the Company to substantial delays in the delivery of its products to its customers. Furthermore, certain key components of the Company’s instruments and certain consumables are manufactured by only one supplier. The Company’s inability to sell products to meet delivery schedules could have a material adverse effect on its reputation in the industry, as well as its financial condition and results of operation.

3.   Acquisition

On July 28, 2010, the Company acquired AlliedPath, Inc. AlliedPath is a high complexity CLIA-certified molecular pathology laboratory offering differentiated, high value molecular diagnostic services in the rapidly growing field of personalized medicine. Pursuant to the terms of the merger agreement dated July 26, 2010, the Company acquired all the issued and outstanding stock of AlliedPath for an amount in cash equal to $4.6 million less certain indebtedness existing at the closing, with an additional earn-out of up to $1.3 million subject to the achievement of specific sales and earnings targets through December 2013. We did not assume any outstanding options or warrants of AlliedPath in connection with the acquisition. AlliedPath is now called Arista Molecular, Inc. (“Arista”) and operates under the Personalized Medicine reporting segment of the consolidated financial statements.

Through the acquisition of Arista, the Company seeks to achieve the following goals:

•  to expand beyond its initial molecular pathology test menu by adding other molecular panels, flow cytometry for the detection and monitoring of leukemia and lymphoma, FISH testing, and proprietary new tests based on the Company’s NADiA technology platform;

•  to have better control of all aspects of the commercial operations of the NADiA platform, starting with NADiA ProsVue;

•  to enable the acceleration of the development efforts of the NADiA technology product pipeline; and

•  to enter the attractive personalized medicine market due to its significant growth potential.

The aggregate consideration paid for the acquisition of Arista was as follows:

	(In thousands)
Cash	$	4,584
Fair value of contingent consideration		1,210
Total purchase price	$	5,794

The aggregate consideration shown above reflects a $46,000 return of purchase price recorded during the six months ended June 30, 2011 (see Note 2, Goodwill and Intangible Assets).

IRIS INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table summarizes the estimated fair values of assets acquired and liabilities assumed as of July 28, 2010.

	(In thousands)
Current assets	$	74
Property and equipment		523
Core technology		3,090
CLIA License		1,604
Customer relationships		6
Non-compete agreements		100
Goodwill		1,461
Other assets		31
Current liabilities		(316	)
Lease obligations		(178	)
Other liabilities		(61	)
Deferred tax liability, net		(540	)
Total purchase price	$	5,794

In determining the purchase price allocation, the Company considered, among other factors, historical demand for products, estimates of future demand for those services, customer relationships, the revenue generating potential of core technology, the assets’ useful lives, and agreements not to compete. The market, income and cost approaches were used to determine fair values of these intangibles. The rate used to discount the net cash flows to their present value was a 16.5% weighted average cost of capital for the business as a whole, and from 16.5% to 17.5% for the individual intangible assets depending on the risk associated with the asset’s potential to generate revenues and its projected remaining useful economic life. The weighted average cost of capital was determined after consideration of market rates of return on debt and equity capital of comparable companies, the weighted average return on invested capital and the risk associated with achieving forecasted sales related to technology and assets acquired. The fair value of the contingent consideration was determined considering the probability of payout and using a 3% discount rate.

Subsequent changes in the fair value of the contingent consideration are recognized as a gain or loss on revaluation of contingent consideration within operating expenses in the Company’s consolidated statement of operations. The Company considers the changes in the fair value of contingent consideration obligation at each reporting date based on changes in discount rates, timing and amount of revenue estimates and changes in probability assumptions with respect to the probability of achieving the obligations. Accretion expense related to the increase in net present value of the contingent liability is included in interest expense for the period. As a result of significant revenue shortfalls at Arista relative to previous projections for the three months ended March 31, 2011, sales projections for Arista were significantly reduced for all future periods. The revised forecast projected revenues are significantly below earn-out targets for all three years covered by the earn-out period. Management thus determined that the fair value contingent consideration obligation was zero, which resulted in a decrease of $1.2 million from December 31, 2010 to March 31, 2011. Consequently the Company recognized a gain on revaluation of contingent consideration for the six months ended June 30, 2011 (recorded in March 2011). As of June 30, 2011, the fair value of the contingent consideration remains zero.

Property and equipment net book value was evaluated at approximately fair value on the acquisition date due to the nature and relative age of the assets acquired.

Acquired property and equipment are being depreciated on a straight-line basis with estimated remaining useful lives ranging from 1 year to 5 years. Intangible assets except the CLIA license are being amortized on a

straight-line basis with estimated remaining useful lives ranging from 3 years to 15 years reflecting the expected future value. The CLIA license is considered to have an indefinite useful life. The purchase was structured as a stock purchase therefore the value assigned to the core technology, CLIA license, customers relationships, non-compete agreements and goodwill is not deductible for tax purposes.

The following table summarizes unaudited pro forma financial information assuming the acquisition of Arista had occurred in the corresponding period of the fiscal year immediately preceding the acquisition. This unaudited pro forma financial information does not necessarily represent what would have occurred if the transaction had taken place on January 1, 2009 (the beginning of the year prior to the acquisition) and should not be taken as representative of the Company’s future consolidated results of operations or financial position.

On November 22, 2010, the Company acquired the assets of a multi-purpose, bench-top instrument platform for automating highly repetitive, manual laboratory protocols for FISH (fluorescence in-situ hybridization) testing and other slide-based cytogenetic applications. The product acquisition is a natural extension to the successful ThermoBrite^® DNA Hybridization System and in line with the Company’s entry into personalized medicine with emphasis on cancer diagnostics. The product prototypes and proprietary technology assets were purchased for $3.2 million in cash from BioMicro Systems, Inc. The new product platform will be integrated into the Iris Sample Processing Division and it is expected to position IRIS as a major competitor in the high growth cytogenetic instrumentation market. This acquisition was recorded as an acquisition of assets determined not to be a business, since no workforce nor strategic management, operational or resource management processes were included in the purchase.

The purchase price of $3.2 million plus related asset acquisition costs of $94,000 was allocated as follows: $3.2 million to core technology, recorded in intangible assets, and $99,000 to property and equipment on the Company’s consolidated balance sheet as of June 30, 2011. The purchase price allocation was based on estimates and available information. Although BioMicro Systems built and tested a working prototype, which proved the technical feasibility of the base technology, several elements of this technology platform require continued development in order to reach salability for its stated purpose. Once development is completed, a useful life for the core technology will be determined and the core technology will be amortized over the useful life determined at that time.

Our leases are primarily to customers in the health care industry or to governments. We assess credit risk for all of our customers including those who lease equipment. Credit risk is assessed using an internally developed model which incorporates credit scores from third party providers and our own custom risk ratings and is updated on a quarterly basis. The external credit scores are developed based on the customer’s historical payment patterns and an overall assessment of the likelihood of delinquent payments. Our internal ratings are weighted based on company size, years in business, and other credit related factors (i.e. profitability, cash flow, liquidity, tangible net worth, etc.). Any one of the following factors may result in a customer being classified as high risk: i) the customer has a history of late payments; ii) the customer has open lawsuits, liens or judgments; and iii) the customer has been in business less than three years. Our lease receivables are collateralized by the equipment’s fair value, which mitigates our credit risk. The following table presents the risk profile by creditworthiness category of our sales-type lease receivables at June 30, 2011:

	(In thousands)
Low risk	$	13,891
Moderate risk		820
High Risk		656
	$	15,367

The balance of the allowance for uncollectible accounts for our sales-type leases was zero as of June 30, 2011. We determine the adequacy of our allowance for uncollectible accounts for sales-type leases based on an analysis of historical write-offs. There have been no write-offs of sales-type lease receivables for the three or six months ended June 30, 2011 or 2010. As of June 30, 2011, the amount of sales-type leases which were past due was not significant

13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

and there were no impaired sales-type leases. Accordingly, there was no material risk of default with respect to sales-type leases as of June 30, 2011.

6.   Bank Credit Facility

The Company has a credit facility with a commercial bank. The credit facility consists of a $6.5 million revolving line of credit for working capital and a $10.0 million line of credit for acquisitions and product opportunities. The credit facility has variable interest rates, which will change from time to time based on changes to either the LIBOR rate or the lender’s prime rate. Borrowings under the credit facility are secured by all of the Company’s assets and mature in June 2012 and June 2015, respectively.

As of June 30, 2011 and December 31, 2010, there were no borrowings under the credit facility. The Company, however, is subject to certain financial and non-financial covenants under the credit facility with the bank and as of June 30, 2011, the Company was in compliance with these covenants.

On July 22, 2011, the Company terminated its then existing credit facility and replaced it with a new credit facility entered into on July 27, 2011 with another commercial bank. See Note 12, Subsequent Events.

7.   Income Taxes

On a quarterly basis, the Company estimates the effective tax rate for the full fiscal year and records a quarterly income tax provision based on the projected effective tax rate. As the fiscal year progresses, the Company refines its estimate based on the facts and circumstances by each tax jurisdiction. The effective tax rates for the three and six months ended June 30, 2011 were 3.6% and 21.5%, respectively. The effective tax rates for the three and six months ended June 30, 2010 were 32% and 33%, respectively.

The Company will recognize potential interest and penalties related to income tax positions as a component of the provision for income taxes in the statements of operations in any future periods in which the Company must record such a liability. Since the Company has not recorded a liability at June 30, 2011, no amount of interest or penalties were recorded in the statement of financial condition or the statement of operations. Accordingly, there was no impact on the Company’s effective tax rate for such items. The Company does anticipate an increase of approximately $500,000 in its unrecognized tax benefits related to certain credit carryforwards anticipated to be generated within the next 12 months. The benefit of such items will be recorded through its statement of operations when recognized.

8.   Stock-Based Compensation

The Company accounts for stock-based compensation pursuant to FASB ASC Topic 505, “Share-Based Payment,” which requires compensation costs related to share-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. Share-based compensation expense for the three and six months ended June 30, 2011 and 2010 includes incremental share-based compensation expense as follows:

Stock Options

The Company has a stock option plan (the 2007 Stock Incentive Plan) under which the Company may grant future non-qualified stock options, incentive stock options and stock appreciation rights. No stock appreciation rights have been granted under any of the Company’s stock option plans. On July 13, 2007, the Company’s stockholders approved the adoption of the IRIS International, Inc. 2007 Stock Incentive Plan, which initially authorized the issuance of up to 1,750,000 shares of common stock pursuant to equity awards granted under the plan. On May 22, 2009, the Company’s stockholders approved an increase of 1,550,000 shares to the 2007 Stock Incentive Plan for a total of 3,300,000 authorized shares.

In addition to the 2007 Stock Incentive Plan, on June 6, 2011, the Company’s board of directors adopted the IRIS International, Inc. 2011 Inducement Incentive Plan (the “2011 Inducement Plan”). The plan provides for the grant of equity-based awards in the form of stock options, restricted common stock, restricted stock units, stock appreciation rights and other stock-based awards solely to “New Employees” as an inducement material to the New Employee’s entering into employment with the Company or any of its subsidiaries within the meaning of Listing Rule 5635(c)(4) (or any successor thereto) of The NASDAQ Stock Market. For purposes of the 2011 Inducement Plan, a “New Employee” means any prospective employee of IRIS International or any of its subsidiaries who either (i) was not previously an employee or director of IRIS International or any of our subsidiaries or (ii) was previously an employee or director of IRIS International or any of its subsidiaries but for which there has occurred a bona fide period of non-employment.

The maximum number of shares available for grant under the 2011 Inducement Plan is 250,000 shares of common stock, which number of shares is subject to adjustment for certain corporate changes, as provided in the plan. The plan expires on June 30, 2013. The plan is administered by the Compensation Committee of the Company’s Board. As of June 30, 2011, no shares have been granted under the 2011 Inducement Plan.

The Company previously had other expired stock option plans which have remaining outstanding shares.

The following schedule sets forth options authorized, exercised, outstanding and available for grant under the Company’s existing stock option plans as of June 30, 2011:

Exercisable at June 30, 2011		1,657		$	12.10		3.3 years	$	928

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the closing stock price on June 30, 2011 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders, had all option holders exercised their options on June 30, 2011. Total intrinsic value of options exercised for the six months ended June 30, 2011 amounted to $171,000. As of June 30, 2011, total unrecognized stock-based compensation expense related to unvested stock options was $4,023,000, which is expected to be recognized over the remaining weighted average period of approximately 2.8 years.

The Compensation Committee of the board of directors determines the total value of the stock based compensation grants. The exercise price of options is the closing price on the date the options are granted. Payment of the exercise price may be made either in cash or with shares of common stock that have been held at least six months. The options generally vest over four years and expire either five or ten years from the date of grant. The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

	For the Three Months
	Ended June 30,
	2011			2010
Risk free interest rate		1.7	%		2.4	%
Expected lives (years)		3.96			5.08
Expected volatility		50.5	%		56.1	%
Expected dividend yield		0	%		0	%

The expected volatilities are based on the historical volatility of the Company’s stock. The observation is made on a weekly basis. The expected terms of the stock options are based on the average vesting period on a basis consistent with the historical experience for similar option grants. The risk-free interest rate is consistent with the expected terms of the stock options and based on the U.S. Treasury yield curve in effect at the time of grant. The Company estimates forfeiture rates based on historical data.

Restricted Shares

The Company began awarding restricted shares of its common stock in 2006. In March 2009, the Company began to grant restricted stock units to its non-employee directors and to certain employees. Such awards generally require that certain performance conditions and service conditions be met before the awards vest. Restricted shares currently vest 25% after one year and 61/4% quarterly thereafter. However, non-employee directors are immediately vested on the grant date. Unvested restricted shares are forfeited if the recipient’s employment terminates for any reason other than death, disability or special circumstances as determined by the Compensation Committee of the Company’s board of directors. Restricted share activity during the six months ended June 30, 2011 was as follows:

				Weighted
				Average
				Grant Date
				Fair Value
	Shares			Per Share
	(In thousands except for fair value per share)
Non-vested shares at January 1, 2011		286		$	10.89

Forfeited		(37	)	$	9.72
Non-vested shares at June 30, 2011		325		$	10.44

Fair value of the Company’s restricted shares is based on the Company’s closing stock price on the date of grant. As of June 30, 2011, total unrecognized stock-based compensation expense related to non-vested restricted share grants was $3,204,000 which is expected to be recognized over the remaining weighted average period of approximately 2.9 years.

9.   Contingencies

Litigation

From time to time, the Company is party to certain litigation arising in the normal course of business. Management believes that the resolution of such matters will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

IRIS INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Guarantees

The Company enters into indemnification provisions under (i) agreements with other companies in the ordinary course of business, typically with business partners, contractors, customers and landlords, and (ii) agreements with investors. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities or, in some cases, as a result of the indemnified party’s activities under the agreement. These indemnification provisions often include indemnifications relating to representations made by the Company with regard to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. In addition, in some cases, the Company has agreed to reimburse employees for certain expenses and to provide salary continuation during short-term disability. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. The Company reviews its exposure under these agreements no less than annually, or more frequently when events indicate. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has not recorded any liabilities for these agreements as of June 30, 2011 or December 31, 2010.

10.   Segments and Geographic Information

The Company’s operations are organized on the basis of products and related services and under FASB ASC Topic 280, Segment Reporting, the Company operates in three segments: (1) Iris Diagnostics Division (IDD), (2) Sample Processing and (3) Personalized Medicine.

The IDD segment designs, develops, manufactures, markets and distributes in-vitro diagnostic systems based on patented and proprietary technology for automating microscopic and clinical chemistry procedures for urinalysis. The segment also provides ongoing sales of consumables and services necessary for the operation of installed urinalysis workstations. In the United States, these products are sold through a direct sales and service force. Internationally, these products are sold and serviced through distributors, with the exception of France, Germany, the United Kingdom and Puerto Rico.

The Sample Processing segment designs, develops, manufactures and markets a variety of bench-top centrifuges, small instruments and supplies. These products are used primarily for manual specimen preparation and dedicated applications in coagulation, cytology, hematology, urinalysis and DNA processing. These products are sold worldwide through distributors.

The Personalized Medicine segment operates a CLIA-certified laboratory focused on oncology and molecular diagnostics services in personalized medicine. This segment also includes the research and development operations of Iris Molecular Diagnostics, or IMD.

The accounting policies of the segments are the same as those described in the “Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010. The Company evaluates the performance of its segments and allocates resources to them based on earnings before income taxes, excluding corporate charges.

On March 25, 2011 the Company entered into a Joint Development Agreement with Fujirebio Inc., one of the largest in-vitro diagnostics companies in Japan, for the co-development of the IRIS 3GEMS^tm Hematology Analyzer product line.

Terms of the agreement call for Fujirebio to contribute $6.0 million toward the costs of the joint development program, with an initial payment of $500,000 upon signing of the agreement in March 2011 and the balance to be paid in installments during the course of the development period based upon the achievement of certain milestones. The Company achieved a milestone in June 2011 and recorded an additional $500,000 due from Fujirebio as of June 30, 2011. These funds will be utilized to accelerate the 3GEMS Hematology Analyzer development program, which leverages IRIS’s proprietary image-based technology to automate the identification and characterization of blood cells, including an image-based expanded white blood cell differential, and is expected to significantly reduce the need for manual slide preparation and reviews. For the three and six months ended June 30, 2011, the Company recorded $500,000 and $1 million, respectively, as a reduction to research and development expenses in the Company’s consolidated statement of operations.

12.   Subsequent Events

The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The Company evaluated subsequent events through the date the financial statements were issued.

On July 22, 2011, the Company terminated its then existing credit facility and replaced it with a new credit facility entered into on July 27, 2011 with JPMorgan Chase Bank, N.A., as administrative agent for certain lenders. The credit facility provides for borrowings of up to $15 million pursuant to revolving loans, acquired participations in letters of credit and swingline loans. The Company has not borrowed any amounts under the credit facility. All amounts under the revolving loans become due and payable on July 31, 2013. The credit facility has variable interest rates, which will change from time to time based on changes to either the applicable LIBOR rate or the lender’s prime rate. Interest is generally payable monthly in arrears. The Company’s obligations under this credit facility are secured by a lien on substantially all of the Company’s assets and those of its domestic subsidiaries. The credit facility contains several performance covenants, limitations on additional indebtedness, and customary default provisions, and all outstanding obligations under the facility may become immediately due and payable in the event of the Company’s default.

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

Overview

IRIS International, Inc. consists of three operating units in three business segments as determined in accordance with FASB ASC Topic 280, Segment Reporting. Our in-vitro diagnostics segment, also called Iris Diagnostics Division (IDD), designs, manufactures and markets systems, consumables and supplies for urinalysis and body fluids. Our Personalized Medicine segment combines the research and development operations of our Iris Molecular Diagnostics and Arista Molecular, Inc. subsidiaries. Under this new segment we consolidate all operations for the development and commercialization of cancer diagnostic testing services and related products. Our Sample Processing segment markets small centrifuges and other processing equipment and accessories for rapid specimen processing, as well as, equipment for fluorescent in-situ hybridization (FISH).

Iris Diagnostics Division

Our core business is in the urinalysis market and we are the leading worldwide provider of automated urine microscopy systems, with more than 3,200 iQ microscopy analyzers shipped to date in over 50 countries. We generate revenues primarily from sales of instruments, consumables and service. Revenues from instruments include global sales of urine microscopy analyzers and sales of chemistry analyzers. In September 2008, we released our proprietary iChemVELOCITY automated urine chemistry analyzer and a fully integrated urine microscopy and urine chemistry work-cell, called the iRICELL in some international markets. In March 2011, we received FDA clearance on our 510(k) application for these products and commenced selling them in the United States. Historically we sold our family of iQ analyzers integrated with an automated chemistry analyzer that were sourced from a Japanese manufacturer.

Our consumables revenues result from sales of chemical reagents, urine test strips, calibrators and controls. Service revenues are derived primarily from annual service contracts purchased by our domestic customers after the initial year of sale, which is covered by product warranty, and spare parts purchased by international customers. Once the analyzers are installed, we generate recurring revenue from sales of consumables. Recurring consumable and service revenues should continue to expand as the installed base of related instruments increases.

In the United States, France, Germany, and the United Kingdom sales of our urinalysis systems are direct to the end-user through our sales force. All other international sales are through independent distributors. International sales represented 33% and 34% of consolidated revenues for the six months ended June 30, 2011 and 2010, respectively. Since the majority of international sales are made through independent distributors, gross profit margin is lower than domestic sales of the same products, but we incur minimal sales, service and marketing costs for such sales.

Personalized Medicine

On July 28, 2010, we acquired Arista Molecular (“Arista”), a high complexity CLIA-certified molecular pathology laboratory offering differentiated, high value molecular diagnostic services in the rapidly growing field of personalized medicine. Pursuant to the terms of the merger agreement dated July 26, 2010, we acquired all the issued and outstanding stock for an amount in cash equal to $4.6 million less certain indebtedness existing at the closing, with an additional earn-out of up to $1.3 million subject to the achievement of specific sales and earnings targets through December 2013 (see discussion of gain on revaluation of contingent consideration below). We did not assume any outstanding options or warrants in connection with the acquisition. Arista operates under the Personalized Medicine reporting segment of the consolidated financial statements.

At the time of acquisition, Arista Molecular was an early-stage laboratory with limited commercial operations. In 2010, we focused the laboratory’s efforts to broaden its menu of diagnostic panels useful for the diagnosis, disease characterization, treatment and monitoring of cancer. We added testing for breast and prostate solid tumors beyond the existing lung and colorectal offering. In addition, we now offer flow cytometry for detection and monitoring of leukemia and lymphoma and FISH testing. Further, we are building the commercial infrastructure of the laboratory by adding sales and marketing personnel. With the expansion of the test menu and sales force, we

22

expect the revenue contribution from this segment to improve in 2011, but continue to have a dilutive impact for the year.

Sample Processing

Our IRIS Sample Processing group markets and develops centrifuges, semi-automated DNA processing workstations and sample processing consumables. Our StatSpin^® brand bench-top centrifuges are used for specimen preparation in coagulation, cytology, chemistry and urinalysis. Our worldwide markets include medical institutions, commercial laboratories, clinics, doctors’ offices, veterinary laboratories and research facilities. Our Sample Processing products are sold worldwide primarily through distributors and incorporated into our OEM partners products.

On November 22, 2010, we acquired the assets of a multi-purpose, bench-top instrument platform for automating highly repetitive, manual laboratory protocols for FISH testing and other slide-based cytogenetic applications. The product acquisition is a natural extension to the successful ThermoBrite^® DNA Hybridization System and in line with our entry into personalized medicine with emphasis on cancer diagnostics. The product prototypes and proprietary technology assets were purchased for $3.2 million in cash from BioMicro Systems, Inc. Although BioMicro Systems built and tested a working prototype, which proved the technical feasibility of the base technology, several elements of this technology platform require continued development in order to reach salability for the platform’s stated purpose.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles and our discussion and analysis of our financial condition and results of operations require us to make judgments, assumptions, and estimates that affect the amounts reported in our consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We regularly discuss with our audit committee the basis of our estimates. Actual results may differ from these estimates and such differences may be material.

A description of our critical accounting policies that represent the more significant judgments and estimates used in the preparation of our financial statements was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, 2010. There have been no material changes in these critical accounting policies since December 31, 2010.

Comparison of Three Months Ended June 30, 2011 to Three Months Ended June 30, 2010

Consolidated revenues for the second quarter ended June 30, 2011 increased 13% to $30.2 million as compared to $26.7 million in the prior year period. IDD urinalysis segment revenues increased 16% to $26.4 million in the second quarter of 2011 as compared to $22.8 million in the prior year quarter. IDD instruments revenues increased 23% to $9.1 million in the second quarter of 2011 as compared to $7.4 million in the prior year quarter. The increase in IDD instrument sales is primarily attributable to strong growth in domestic sales of both iChemVelocity and iRICELL workstations, following the recent FDA clearance of the iChemVelocity in March 2011. International instruments also experienced year over year growth primarily due to increased sales in the Asia Pacific and Latin America regions.

24

IDD consumables and service revenues increased 13% to a record $17.3 million in the second quarter of 2011 as compared to $15.3 million in the prior year quarter. The increase in both consumables and service revenue was primarily due to the larger installed base of instruments. In particular, we experienced an increase in sales of Japanese sourced chemistry strips due to higher utilization, and an increase in sales of our iChemVELOCITY strips as a result of increased placements of our iChemVELOCITY analyzer. We expect sales of our iChemVELOCITY strips to accelerate with the recent introduction of the iChemVELOCITY in the domestic market and planned availability in international markets that require FDA clearance prior to product registration in those markets.

Revenues from Sample Processing instruments and supplies decreased 7% to $3.7 million in the second quarter of 2011 as compared to $4.0 million in the prior year quarter. The decrease was primarily attributable to lower instrument sales to several of our OEM partners, partially offset by higher sales to our North American distributors.

Personalized Medicine revenues in the second quarter of 2011 totaled $104,000 as we continue to expand our test menu and build out our sales force. There were no revenues in this segment in the prior year period as Arista was purchased in July 2010.

Consolidated gross profit margin was 52% during the second quarter of 2011 compared to 54% in the prior year quarter. Excluding losses from the Personalized Medicine segment, consolidated gross margin was 54%. Decreases in consumables and service margins and Sample Processing gross margins were offset by an increase in IDD instrument margins.

The gross profit margin of our IDD instruments was 44% in the second quarter of 2011 as compared to 37% in the prior year quarter. The increase in instrument margins is primarily due to increased volume, which drove overhead efficiencies in our manufacturing operations, lower rework costs and regional mix as a greater proportion of our sales were in the U.S. market.

The gross margin of our IDD consumables and services decreased to 58% in the second quarter of 2011 from 62% in the prior year quarter. The decrease was primarily attributable to higher costs for Japanese sourced chemistry strips due to the appreciation of the Yen versus a year ago as well as an increase in service personnel to support our increasing installed base.

Gross profit margin for our Sample Processing segment was 54% during the second quarter of 2011 and 56% in the prior year quarter. The decrease was primarily due to product mix and lower overhead absorption.

Marketing and selling expenses increased to $6.0 million, or 20% of revenues, in the second quarter of 2011 as compared to $4.8 million, or 18% of revenues, for the second quarter of 2010. Excluding $862,000 of expenses related to Arista, which was not in the prior year period, marketing and selling expenses were 17% of revenues due to higher commissions from increased instrument sales and GPO fees of $140,000, and increased travel and trade show expenses of $134,000 and $52,000 in other miscellaneous items.

General and administrative expenses increased to $5.8 million, or 19% of revenues, in the second quarter of 2011, as compared to $4.6 million, or 17% of revenues, in the second quarter of 2010. Excluding $713,000 of expenses related to Arista, which was not in the prior year period, expenses were 17% of revenues due to an increase in stock based compensation expenses of $369,000, board cash compensation expense of $216,000 and an increase in bonus expense of $259,000. In the second quarter of 2011, our board of directors changed the composition of non-employee director compensation to a higher proportion of stock versus stock options to conserve options available for employee grants under our existing stock incentive plan. While the total compensation paid to non-employee directors remained the same, the change did cause us to recognize in the second quarter 100% of the equity compensation expense for non-employee directors. In previous periods, equity compensation expense was recognized over a twelve month period. We anticipate a decrease in equity compensation expense for non-employee directors over the future 12-month period. Additionally, we recognized $250,000 of bonus expense during the second quarter of 2011 related to a performance based cash award to our CEO upon his achievement of two critical 2010 milestones which were delayed into 2011. The above items were partially offset by a decrease in professional services, recruiting and other corporate expenses of approximately $390,000.

25

Research and development expenses increased to $4.5 million, or 15% of revenues in the second quarter of 2011, as compared to $3.8 million, or 14% of revenues, in the second quarter of 2010. The increase in research and development expense includes the development of the FISH testing bench-top platform for Sample Processing and IDD research and development expenses to support our 3GEMS urinalysis and hematology programs. The second quarter of 2011 R&D expense is net of a $500,000 payment from Fujirebio related to the achievement of a milestone in our 3GEMS Hematology joint development agreement.

Interest income decreased during the second quarter of 2011 to $272,000 from $279,000 during the second quarter of 2010, due primarily to the decrease in cash and cash equivalents partially offset by an increase in interest income from investment in sales-type leases.

Foreign exchange gains and other totaled $28,000 for the second quarter of 2011 as compared to a $589,000 loss in the prior year period, primarily resulting from the effect of favorable foreign currency fluctuations on U.S. dollar denominated intercompany balances.

Income tax during the second quarter of 2011 amounted to a benefit of 3.6% of pre-tax loss as compared to 32% of pre-tax income during the prior year period. The lower tax rate reflects the effects of permanent differences such as the gain on revaluation of contingent consideration which is not taxable for federal and state income tax purposes, as well as the impact of federal and state research and development tax credits, relative to the amounts of income projected for the year.

Comparison of Six Months Ended June 30, 2011 to Six Months Ended June 30, 2010

Consolidated revenues for the six months ended June 30, 2011 increased 8% to $57.1 million as compared to $52.7 million in the prior year period. IDD urinalysis segment revenues increased 10% to $49.7 million in the first half of 2011 as compared to $45.0 million in the prior year period. IDD instruments revenues increased 2% to $15.6 million in the first half of 2011 as compared to $15.3 million in the prior year period. The increase in IDD instrument sales is primarily attributable to the growth in the second quarter of 2011 as the first quarter included promotional discounts offered to domestic customers who bought a remanufactured version of the predecessor chemistry analyzers prior to the recent FDA clearance of iChemVELOCITY and iRICELL.

IDD consumables and service revenues increased 15% to $34.0 million in the first half of 2011 as compared to $29.7 million in the prior year period. The increase in both consumables and service revenue was primarily driven by the larger installed base of instruments. In particular, we experienced an increase in sales of Japanese sourced chemistry strips due to higher utilization, and an increase in sales of our iChemVELOCITY strips as a result of increased placements. We expect sales of our iChemVELOCITY strips to accelerate now that we are selling the iChemVELOCITY in the domestic market and planned availability in international markets that require FDA clearance prior to product registration in those markets.

Revenues from Sample Processing instruments and supplies decreased 5% to $7.3 million in the first half of 2011 as compared to $7.7 million in the prior year period. The decrease was primarily attributable to lower service and spare parts revenue and a non-recurring OEM order in the first half of 2010 for a product that we sold the manufacturing rights for to one of our major customers.

Personalized Medicine revenues in the first half of 2011 totaled $168,000 as we continue to expand our test menu and build out our sales force. There were no revenues in this segment in the prior year period as Arista was purchased in July 2010.

Overall gross profit margin was 50% during the first half of 2011 compared to 53% in the prior year period. Excluding losses from the Personalized Medicine segment, consolidated gross margin was 52%. The remaining 1% decrease was due to lower margins in IDD consumables and service and Sample Processing products, partially offset by an increase in IDD instrument margins.

The gross profit margin of our IDD instruments was 40% in the first half of 2011 as compared to 36% in the prior year period. The increase in instrument margins is primarily due to increased volume, which drove overhead efficiencies in our manufacturing operations, lower rework costs and regional mix as a greater proportion of our sales were in the U.S. market.

26

The gross margin of our IDD consumables and services decreased to 57% in the first half of 2011 from 61% in the prior year period. The decrease was primarily attributable to higher costs for Japanese sourced chemistry strips due to the appreciation of the Yen versus a year ago, as well as an increase in service personnel to support our increasing installed base.

Gross profit margin for our Sample Processing segment was 54% during the first half of 2011 and 55% in the prior year period. The decrease was primarily attributable to product mix and lower overhead absorption that occurred in the second quarter of 2011.

Marketing and selling expenses increased to $11.9 million, or 21% of revenues, in the first half of 2011 as compared to $9.2 million, or 17% of revenues, for the first half of 2010. Excluding $1.8 million of expenses related to Arista, which was not in the prior year period, expenses were 18% of revenues driven by additional personnel and related costs of $186,000, higher commissions on higher revenues and GPO fees of $310,000, and increased travel and trade show expenses of $465,000.

General and administrative expenses increased to $10.6 million, or 19% of revenues, in the first half of 2011, as compared to $8.4 million, or 16% of revenues, in the first half of 2010. Excluding $1.5 million of expenses related to Arista, expenses were 16% of revenue reflecting an increase in stock based compensation and board cash compensation of $515,000 and other personnel and related costs of $357,000.

Research and development expenses increased to $8.1 million, or 14% of revenues in the first half of 2011, as compared to $7.5 million, or 14% of revenues, in the first half of 2010. The increase in research and development expense includes the development of the FISH testing bench-top platform for Sample Processing, IDD research and development costs to support our 3GEMS urinalysis and hematology programs and assay development at Arista molecular. These were partially offset by a decrease in expenses related to our NADiA platform as we incurred costs in the prior year quarter associated with preparing our 510(k) submission of our prostate cancer test, NADiA ProsVue, to the FDA. The first half of 2011 R&D expense includes two payments totaling $1 million from Fujirebio related to our joint development agreement on the 3GEMS Hematology Analyzer which offsets research and development expenditures for this product.

Gain on revaluation of contingent consideration of $1.2 million recorded in the first half of 2011 is the result of the reduction in the fair value of the contingent consideration obligation associated with the acquisition of Arista. As a result of significant revenue shortfalls at Arista relative to previous projections for the three months ended March 31, 2011, sales projections for Arista were significantly reduced for all future periods. The revised forecast projected revenues are significantly below targets for all three years covered by the earn-out period. Management thus determined that the fair value contingent consideration obligation was zero, which resulted in a decrease of $1.2 million from December 31, 2010 to March 31, 2011. Consequently the Company recognized a gain on revaluation of contingent consideration for the six months ended June 30, 2011 (recorded in March 2011). As of June 30, 2011, the fair value of the contingent consideration remains zero.

Interest income increased during the first half of 2011 to $549,000 from $516,000 during the first half of 2010, due primarily to an increase in interest income from investment in sales-type leases.

Foreign exchange gains and other totaled $414,000 for the first half of 2011 as compared to a $692,000 loss in the prior year period, primarily resulting from the effect of favorable foreign currency fluctuations on U.S. dollar denominated intercompany balances.

Income tax during the first half of 2011 amounted to a provision of 21.5% of pre-tax income as compared to 33% during the prior year period. The lower tax rate reflects the effects of permanent differences such as the gain on revaluation of contingent consideration which is not taxable for federal and state income tax purposes, as well as the impact of federal and state research and development tax credits, relative to the amounts of income projected for the year.

27

Liquidity and Capital Resources

Our primary source of liquidity is cash from operations, which depends heavily on sales of our IDD instruments, consumables and service, as well as sales of sample processing instruments and supplies. At June 30, 2011, our cash and cash equivalents amounted to $20.8 million compared to $25.5 million at December 31, 2010.

In the past few years, we have faced adverse macro-economic forces, which have impacted our selling markets and the credit markets of our customers. At this point the impact from these forces are relatively mild, but in the future we may face the following challenges: deferrals of purchases due to decreases in capital budgets of our customers, delays in the purchasing cycle due to greater scrutiny of deals and increased internal competition for limited capital dollars, and an increase in requests for quotes for operating leases. The aforementioned factors may lead to a decrease in revenue, an increase of deferred revenue, or could lead to installment cash collection.

Operating Cash Flows.  Cash provided by operations for the six months ended June 30, 2011 was $0.1 million as compared to $5.3 million in the prior year period, primarily due to the decrease in net income adjusted for non-cash items and due to an increase in accounts receivable and inventories.

As of June 30, 2011, the number of days sales in accounts receivable increased to 74 days compared to 63 days for the prior year first half. The number of days sales in accounts receivable varies and may increase with extended payment terms to our international distributors and end users.

Investing Activities.  Cash used in investing activities totaled $4.9 million in the six months ended June 30, 2011 as compared to $2.2 million in the prior year period, primarily due to increased purchases of property and equipment resulting from an investment in leasehold improvements for the Company’s new research and development facility located in Chatsworth, CA.

Financing Activities.  Cash used in financing activities totaled $58,000 in the six months ended June 30, 2011 compared to $153,000 in the prior year period. Financing activities in both periods were primarily composed of settlement on restricted stock tax withholding.

We currently have a credit facility with a commercial bank consisting of a $6.5 million revolving line of credit for working capital and a $10.0 million line of credit for acquisitions and product opportunities. The credit facility has variable interest rates, which will change from time to time based on changes to either the LIBOR rate or the lender’s prime rate. As of June 30, 2011, there were no borrowings under the credit facility. We are subject to certain financial and non-financial covenants under the credit facility with the bank and as of June 30, 2011, we were in compliance with these covenants.

On July 22, 2011, we terminated our then existing credit facility and replaced it with a new credit facility entered into on July 27, 2011 with JPMorgan Chase Bank, N.A., as administrative agent for certain lenders. The credit facility provides for borrowings of up to $15 million pursuant to revolving loans, acquired participations in letters of credit and swingline loans. We have not borrowed any amounts under the credit facility. All amounts under the revolving loans become due and payable on July 31, 2013. The credit facility has variable interest rates, which will change from time to time based on changes to either the applicable LIBOR rate or the lender’s prime rate. Interest is generally payable monthly in arrears. Our obligations under this credit facility are secured by a lien on substantially all of our assets and those of our domestic subsidiaries. The credit facility contains several performance covenants, limitations on additional indebtedness, and customary default provisions, and all outstanding obligations under the facility may become immediately due and payable in the event of our default.

We believe that our current cash on hand, together with cash generated from operations and cash available under our new credit facility with the bank will be sufficient to fund normal operations for the foreseeable future. However, additional funding may be required to fund expansion of our business. There is no assurance that such funding will be available on terms acceptable to us.

Off-Balance Sheet Arrangements

At June 30, 2011 and 2010, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or

28

limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Recent Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU No. 2011-05, Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income. ASU 2011-05 amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of stockholders’ equity. Instead, entities must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after December 15, 2011 with early adoption permitted. We do not expect the adoption of ASU 2011-02 to have a material impact on our financial statements as it only requires a change in the format of our current presentation.

In April 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2011-02, Receivables: A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring. ASU 2011-02 provides guidance on whether a restructuring constitutes a troubled debt restructuring. For public entities, the ASU is effective for the first interim or annual period beginning on or after June 15, 2011, and should be applied retrospectively to the beginning of the annual period of adoption. For purposes of measuring impairment of those receivables, an entity should apply the amendments prospectively for the first interim or annual period beginning on or after June 15, 2011. For nonpublic entities, the ASU is effective for annual periods ending on or after December 15, 2012, including interim periods within those annual periods. Early adoption is permitted. We do not expect the adoption of ASU 2011-02 to have a material impact on our financial statements.

In December 2010, the FASB issued ASU 2010-29, Business Combinations- Disclosure of Supplementary Pro Forma Information, which specifies that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only.

ASU 2010-29 is effective on a prospective basis for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010 with early adoption permitted. The adoption of ASU 2010-29 did not have a material impact on our financial statements.

In December 2010, the FASB issued ASU No. 2010-28 — When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts. This update provides amendments to ASC Topic 350 — Intangibles, Goodwill and Other that requires an entity to perform Step 2 impairment test even if a reporting unit has zero or negative carrying amount. Step 1 tests whether the carrying amount of a reporting unit exceeds its fair value. Previously reporting units with zero or negative carrying value passed Step 1 because the fair value was generally greater than zero. Step 2 requires impairment testing and impairment valuation be calculated in between annual tests if an event or circumstances indicate that it is more likely than not that goodwill has been impaired. ASU 2010-28 is effective beginning January 1, 2011. As a result of this standard, goodwill impairments may be reported sooner than under current practice. The adoption of ASU 2010-28 did not have a material impact on our financial statements.

In April 2010, the FASB issued ASU 2010-17, Milestone Method of Revenue Recognition, provides guidance on defining a milestone and determining when it may be appropriate to apply the milestone method of revenue recognition for research and development transactions. It is effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years, beginning on or after June 15, 2010. Early adoption is permitted. The adoption of the ASU 2010-17 did not have a material impact on our consolidated financial statements.

In October 2009, the FASB issued ASU 2009-14, Certain Revenue Arrangements That Include Software Elements, now codified under FASB ASC Topic 985, Software. ASU 2009-14, removes tangible products from the scope of software revenue guidance and provides guidance on determining whether software deliverables in an arrangement that includes a tangible product are covered by the scope of the software revenue guidance. ASU

29

2009-14 is to be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with early adoption permitted. The adoption of the ASU 2009-14 did not have a material impact on our consolidated financial statements.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk

Market Risk

Our business is exposed to various market risks, including changes in interest rates and foreign currency exchange rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates and foreign currency exchange rates. We do not invest in derivatives, foreign currency forward contracts or other financial instruments for trading or speculative purposes. We had no debt at June 30, 2011, thus were not subject to market risk for changes in interest rates on debt obligations. We are subject to market risk for changes in interest rates on our short-term investment portfolio. We invest our excess cash in certificates of deposit and, on occasion, other short-term investments, and the market value of these investments fluctuates based on changes in interest rates.

Foreign Currencies

We conduct business in certain foreign markets, primarily in the European Union and Asia. Our primary exposure to foreign currency risk relates to investments in foreign subsidiaries that transact business in a functional currency other than the U.S. Dollar, primarily the Euro and British Pound. We are subject to certain foreign currency risks in the importation of goods from Japan and as a result of commercial operations in Europe and Asia. Our consumables purchases from a major Japanese IVD supplier are denominated in Japanese Yen. The impact from fluctuation in the Yen should decrease over time, as we now sell our own chemistry analyzer into the domestic market. All of our sales are denominated in U.S. Dollars with the exception of France, Germany, the United Kingdom and Ireland, where sales are denominated in Euros and British Pound. Fluctuations in the U.S. Dollar exchange rate for Japanese Yen, Euro and British Pound could result in increased costs for our key components and increased costs for commercial operations in Europe.

Item 4.   Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined by paragraph (e) of Rules 13a-15(f) or 15d-15(f) under the Securities and Exchange Act of 1934, as amended, designed to ensure that we are able to collect the information we are required to disclose in the reports we file with the SEC and to approve, summarize and disclose this information within the time periods specified in the rules of the SEC. Our Chief Executive Officer and Chief Financial Officer are responsible for establishing and maintaining these procedures, and, as required by the rules of the SEC, evaluate their effectiveness. Our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2011, the end of the period covered by this report, and based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting during the period ended June 30, 2011 that materially affected, or is reasonable likely to materially affect, our internal control over financial reporting.

Bank Credit Facility

6.   Bank Credit Facility

The Company has a credit facility with a commercial bank. The credit facility consists of a $6.5 million revolving line of credit for working capital and a $10.0 million line of credit for acquisitions and product opportunities. The credit facility has variable interest rates, which will change from time to time based on changes to either the LIBOR rate or the lender’s prime rate. Borrowings under the credit facility are secured by all of the Company’s assets and mature in June 2012 and June 2015, respectively.

As of June 30, 2011 and December 31, 2010, there were no borrowings under the credit facility. The Company, however, is subject to certain financial and non-financial covenants under the credit facility with the bank and as of June 30, 2011, the Company was in compliance with these covenants.

On July 22, 2011, the Company terminated its then existing credit facility and replaced it with a new credit facility entered into on July 27, 2011 with another commercial bank. See Note 12, Subsequent Events.

Description Of Business [Abstract]

Joint Development Agreement

11.   Joint Development Agreement

On March 25, 2011 the Company entered into a Joint Development Agreement with Fujirebio Inc., one of the largest in-vitro diagnostics companies in Japan, for the co-development of the IRIS 3GEMS^tm Hematology Analyzer product line.

Terms of the agreement call for Fujirebio to contribute $6.0 million toward the costs of the joint development program, with an initial payment of $500,000 upon signing of the agreement in March 2011 and the balance to be paid in installments during the course of the development period based upon the achievement of certain milestones. The Company achieved a milestone in June 2011 and recorded an additional $500,000 due from Fujirebio as of June 30, 2011. These funds will be utilized to accelerate the 3GEMS Hematology Analyzer development program, which leverages IRIS’s proprietary image-based technology to automate the identification and characterization of blood cells, including an image-based expanded white blood cell differential, and is expected to significantly reduce the need for manual slide preparation and reviews. For the three and six months ended June 30, 2011, the Company recorded $500,000 and $1 million, respectively, as a reduction to research and development expenses in the Company’s consolidated statement of operations.

Interim Financial Reporting

6 Months Ended

Jun. 30, 2011

Quarterly Financial Information Disclosure [Abstract]

Interim Financial Reporting

2.   Interim Financial Reporting

Basis of Presentation — The financial statements have been prepared in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended, and do not include all of the information and note disclosures required by accounting principles generally accepted in the United States (“GAAP”). These financial statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

The Consolidated Financial Statements included herein are unaudited, but in the opinion of management, such financial statements include all adjustments, including normal recurring adjustments, necessary to summarize fairly the Company’s financial position and results of operations for the interim periods. The results reported in these Consolidated Financial Statements for the interim periods should not be taken as indicative of results that may be expected for the entire year.

Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The significant estimates in the preparation of the consolidated financial statements relate to the assessment of the carrying allowance for doubtful accounts, inventory reserves, the useful lives, fair value and recoverability of carrying value of long-lived and intangible assets, including goodwill, unearned income on sales-type leases, estimated provisions for warranty costs, laboratory information system implementations, contingent consideration and deferred tax assets. Actual results and outcomes may differ from management’s estimates and assumptions.

Earnings Per Share — The Company computes and presents earnings per share in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 260, Earnings per share. Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants using the average market prices during the period. The weighted average number of outstanding antidilutive common stock options excluded from the computation of diluted net income per common share for the three and six months ended June 30, 2011 were 2,636,703 and 2,465,746, respectively. The weighted average number of outstanding antidilutive common stock options excluded from the computation of diluted net income per common share for the three and six months ended June 30, 2010 was 1,830,000 in both periods. A reconciliation of the shares used in the calculation of basic and diluted earnings per common share is as follows:

	For the				For the
	Three Months Ended				Six Months Ended

Weighted average common shares outstanding — diluted		17,764		18,094		17,829		18,079

Foreign Currency Hedge — The Company conducts business in certain foreign markets, primarily in the European Union and Asia. To mitigate the potential impact of adverse fluctuations in the U.S. Dollar exchange rate for these currencies, the Company may periodically purchase foreign currency forward contracts. The Company does not speculate in these hedging instruments in order to profit from foreign currency exchanges nor does the Company enter into trades for which there are no underlying exposures.

Under FASB ASC Topic 815, Accounting for Derivative Instruments and Hedging Activities, the Company documents all relationships between hedging instruments and hedged items, as well as its risk management objective for undertaking these hedging transactions. This process includes relating the forward contracts that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedged items.

At June 30, 2011 and 2010, the Company did not have any foreign currency forward contracts.

Goodwill and Intangible Assets — Goodwill represents the excess of the aggregate purchase price over the fair value of the tangible and identifiable intangible assets acquired by the Company. Goodwill and intangible assets with indefinite lives, which consists of a CLIA license, are not amortized. Goodwill and intangible assets with indefinite lives are subject to impairment tests on an annual basis or more frequently if facts and circumstances warrant such a review. Goodwill and intangible assets with indefinite lives are evaluated in accordance with FASB ASC Topic 350, Intangibles-Goodwill and Other (“ASC 350”), based on various analyses, including a comparison of the carrying value of the reporting unit to its estimated fair value and discounted cash flows. The analysis necessarily involves significant management judgment to evaluate the capacity of an acquired business to perform within projections. If the carrying amount of a reporting unit exceeds its fair value, the goodwill impairment test is performed to measure the amount of the impairment loss, if any. During the six months ended June 30, 2011 and 2010, the Company did not record any impairment charges related to goodwill or intangible assets with indefinite lives.

Intangible assets are initially measured at their fair value, determined either by the fair value of the consideration exchanged for the intangible asset, or the estimated discounted cash flows expected to be generated from the intangible asset. Intangible assets with a finite life, such as core technology, customer relationships and non-compete agreements are amortized on a straight-line basis over their estimated useful life, ranging from 3 to 20 years. Intangible assets with a finite life are evaluated for impairment using the methodology set forth in FASB ASC Topic 360, Property, Plant and Equipment. Recoverability of these assets is assessed only when events have occurred that may give rise to a potential impairment. When a potential impairment has been identified, forecasted undiscounted net cash flows of the operations to which the asset relates are compared to the current carrying value of the long-lived assets present in that operation. If such cash flows are less than such carrying amounts, long-lived assets, including such intangibles, are written down to their respective fair values. During the six months ended June 30, 2011 and 2010, no intangible asset impairment was recorded.

In determining the useful lives of intangible assets, the Company considers the expected use of the assets and the effects of obsolescence, demand, competition, anticipated technological advances, market influences and other economic factors. For technology based intangible assets, the Company considers the expected life cycles of products which incorporate the corresponding technology.

Goodwill decreased $46,000 during the six months ended June 30, 2011 due to a return of purchase price from the seller of AlliedPath, Inc. (now Arista Molecular, Inc.) as a result of a settlement of claims made against funds escrowed as security for representations and warranties pursuant to the merger agreement, dated July 26, 2010. All of the goodwill balance relates to the Personalized Medicine segment.

Foreign Currency Exchange Translation — The functional currencies of the Company’s foreign subsidiaries are primarily accounted for in their respective local currencies. The statements of operations of foreign operations are translated into U.S. dollars at rates of exchange in effect each month. The balance sheets of these subsidiaries are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in stockholders’ equity as other comprehensive income (loss). Foreign currency transaction gains and losses from certain intercompany transactions are recorded in foreign currency transaction gain (loss) in other income (expense). Transactions denominated in currencies other than the functional currency are recorded based on rates in effect at the time such transactions arise. Subsequent changes in exchange rates result in transaction gains and losses and are reflected in the accompanying consolidated statements of operations as unrealized (based on the applicable period-end exchange rate) or realized based upon settlement of the transactions. All other foreign currency gains and losses are also recorded in foreign currency transaction gain (loss) and other. The Company recognized net foreign currency transaction gain of $28,000 and $414,000 for the three and six months ended June 30, 2011. The Company recognized net foreign currency transaction losses of $589,000 and $692,000 for the three and six months ended June 30, 2010. Such gains and losses were primarily attributable to volatility in the Euro and British Pound.

Foreign currency exchange gains (losses) related to intercompany balances were recorded in the Company’s statements of operations through June 30, 2011 as they represented short-term intercompany trade payables and receivables. On March 31, 2011, a substantial portion of the Company’s intercompany balances from its European subsidiaries were converted to promissory notes that are of a long-term investment nature (settlement of these notes is not planned or anticipated in the foreseeable future). As a result, foreign exchange gains and losses attributable to these promissory notes are recorded in stockholders’ equity as other comprehensive income (loss) beginning April 1, 2011.

Reclassifications — The Company reclassified amounts in segment and geographic information in prior periods to add the new operating segment, Personalized Medicine (which is further described in the Segments and Geographic footnote), to conform to the presentation used in the current period. The Personalized Medicine composition includes the research and development operations of Iris Molecular Diagnostics which had been included with the IDD segment in prior periods. These reclassifications had no impact on the Company’s previously reported income from operations, net income or basic or diluted earnings per share.

Certain Risks and Uncertainties — Financial instruments, which potentially expose the Company to concentration of credit risk, consist primarily of cash and cash equivalents, accounts receivable and investment in sales-type leases. Concentration of credit risk with respect to accounts receivable and investment in sales-type leases is mitigated by the Company’s performance of on-going credit evaluations of its customers and the Company maintains an allowance for doubtful accounts. Investments in sales-type leases are secured by the underlying instruments.

At June 30, 2011, the amount of the Company’s cash deposited in demand deposit accounts which are fully guaranteed by the Federal Deposit Insurance Corporation was $10.1 million. The rest of the cash balances on deposit with banks are guaranteed by the Federal Deposit Insurance Corporation up to $250,000. The Company may be exposed to risk for the amount of funds held in one bank in excess of the insurance limit. In assessing the risk, the Company’s policy is to maintain cash balances with high quality financial institutions.

The Company derives most of its revenues from the sale of the urinalysis analyzers, and related supplies and services. Relatively modest declines in unit sales or gross margins could have a material adverse effect on the Company’s revenues and profits, respectively.

Certain of the Company’s components are obtained from outside vendors, and the loss or breakdown of the Company’s relationships with these outside vendors could subject the Company to substantial delays in the delivery of its products to its customers. Furthermore, certain key components of the Company’s instruments and certain consumables are manufactured by only one supplier. The Company’s inability to sell products to meet delivery schedules could have a material adverse effect on its reputation in the industry, as well as its financial condition and results of operation.

Stock-Based Compensation

8.   Stock-Based Compensation

The Company accounts for stock-based compensation pursuant to FASB ASC Topic 505, “Share-Based Payment,” which requires compensation costs related to share-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. Share-based compensation expense for the three and six months ended June 30, 2011 and 2010 includes incremental share-based compensation expense as follows:

Stock Options

The Company has a stock option plan (the 2007 Stock Incentive Plan) under which the Company may grant future non-qualified stock options, incentive stock options and stock appreciation rights. No stock appreciation rights have been granted under any of the Company’s stock option plans. On July 13, 2007, the Company’s stockholders approved the adoption of the IRIS International, Inc. 2007 Stock Incentive Plan, which initially authorized the issuance of up to 1,750,000 shares of common stock pursuant to equity awards granted under the plan. On May 22, 2009, the Company’s stockholders approved an increase of 1,550,000 shares to the 2007 Stock Incentive Plan for a total of 3,300,000 authorized shares.

In addition to the 2007 Stock Incentive Plan, on June 6, 2011, the Company’s board of directors adopted the IRIS International, Inc. 2011 Inducement Incentive Plan (the “2011 Inducement Plan”). The plan provides for the grant of equity-based awards in the form of stock options, restricted common stock, restricted stock units, stock appreciation rights and other stock-based awards solely to “New Employees” as an inducement material to the New Employee’s entering into employment with the Company or any of its subsidiaries within the meaning of Listing Rule 5635(c)(4) (or any successor thereto) of The NASDAQ Stock Market. For purposes of the 2011 Inducement Plan, a “New Employee” means any prospective employee of IRIS International or any of its subsidiaries who either (i) was not previously an employee or director of IRIS International or any of our subsidiaries or (ii) was previously an employee or director of IRIS International or any of its subsidiaries but for which there has occurred a bona fide period of non-employment.

The maximum number of shares available for grant under the 2011 Inducement Plan is 250,000 shares of common stock, which number of shares is subject to adjustment for certain corporate changes, as provided in the plan. The plan expires on June 30, 2013. The plan is administered by the Compensation Committee of the Company’s Board. As of June 30, 2011, no shares have been granted under the 2011 Inducement Plan.

The Company previously had other expired stock option plans which have remaining outstanding shares.

The following schedule sets forth options authorized, exercised, outstanding and available for grant under the Company’s existing stock option plans as of June 30, 2011:

	Number of Option Shares
							Available

Stock option activity during the six months ended June 30, 2011 is as follows:

				Weighted		Weighted
				Average		Average
				Exercise		Remaining		Aggregate
				Price Per		Contractual		Intrinsic
	Shares			Share		Term		Value
	(In thousands, except for per share amounts)
Outstanding at January 1, 2011		2,769		$	12.26		4.8 years	$	1,564

Exercisable at June 30, 2011		1,657		$	12.10		3.3 years	$	928

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the closing stock price on June 30, 2011 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders, had all option holders exercised their options on June 30, 2011. Total intrinsic value of options exercised for the six months ended June 30, 2011 amounted to $171,000. As of June 30, 2011, total unrecognized stock-based compensation expense related to unvested stock options was $4,023,000, which is expected to be recognized over the remaining weighted average period of approximately 2.8 years.

The Compensation Committee of the board of directors determines the total value of the stock based compensation grants. The exercise price of options is the closing price on the date the options are granted. Payment of the exercise price may be made either in cash or with shares of common stock that have been held at least six months. The options generally vest over four years and expire either five or ten years from the date of grant. The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

	For the Three Months
	Ended June 30,
	2011			2010
Risk free interest rate		1.7	%		2.4	%
Expected lives (years)		3.96			5.08
Expected volatility		50.5	%		56.1	%
Expected dividend yield		0	%		0	%

The expected volatilities are based on the historical volatility of the Company’s stock. The observation is made on a weekly basis. The expected terms of the stock options are based on the average vesting period on a basis consistent with the historical experience for similar option grants. The risk-free interest rate is consistent with the expected terms of the stock options and based on the U.S. Treasury yield curve in effect at the time of grant. The Company estimates forfeiture rates based on historical data.

A summary of the Company’s non-vested stock options during the six months ended June 30, 2011 is as follows:

				Weighted
				Average
				Grant Date
				Fair Value
	Shares			Per Share
	(In thousands except for fair value per share)
Non-vested options at January 1, 2011		1,127		$	4.80
Granted		272		$	4.07
Vested		(297	)	$	5.20
Forfeited		(122	)	$	4.14
Non-vested options at June 30, 2011		980		$	4.55

Restricted Shares

The Company began awarding restricted shares of its common stock in 2006. In March 2009, the Company began to grant restricted stock units to its non-employee directors and to certain employees. Such awards generally require that certain performance conditions and service conditions be met before the awards vest. Restricted shares currently vest 25% after one year and 61/4% quarterly thereafter. However, non-employee directors are immediately vested on the grant date. Unvested restricted shares are forfeited if the recipient’s employment terminates for any reason other than death, disability or special circumstances as determined by the Compensation Committee of the Company’s board of directors. Restricted share activity during the six months ended June 30, 2011 was as follows:

				Weighted
				Average
				Grant Date
				Fair Value
	Shares			Per Share
	(In thousands except for fair value per share)
Non-vested shares at January 1, 2011		286		$	10.89
Granted		204		$	9.51
Vested		(128	)	$	10.18
Forfeited		(37	)	$	9.72
Non-vested shares at June 30, 2011		325		$	10.44

Fair value of the Company’s restricted shares is based on the Company’s closing stock price on the date of grant. As of June 30, 2011, total unrecognized stock-based compensation expense related to non-vested restricted share grants was $3,204,000 which is expected to be recognized over the remaining weighted average period of approximately 2.9 years.

Commitments and Contingencies Disclosure [Abstract]

Contingencies

9.   Contingencies

Litigation

From time to time, the Company is party to certain litigation arising in the normal course of business. Management believes that the resolution of such matters will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Guarantees

The Company enters into indemnification provisions under (i) agreements with other companies in the ordinary course of business, typically with business partners, contractors, customers and landlords, and (ii) agreements with investors. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities or, in some cases, as a result of the indemnified party’s activities under the agreement. These indemnification provisions often include indemnifications relating to representations made by the Company with regard to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. In addition, in some cases, the Company has agreed to reimburse employees for certain expenses and to provide salary continuation during short-term disability. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. The Company reviews its exposure under these agreements no less than annually, or more frequently when events indicate. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has not recorded any liabilities for these agreements as of June 30, 2011 or December 31, 2010.

Income Taxes

7.   Income Taxes

On a quarterly basis, the Company estimates the effective tax rate for the full fiscal year and records a quarterly income tax provision based on the projected effective tax rate. As the fiscal year progresses, the Company refines its estimate based on the facts and circumstances by each tax jurisdiction. The effective tax rates for the three and six months ended June 30, 2011 were 3.6% and 21.5%, respectively. The effective tax rates for the three and six months ended June 30, 2010 were 32% and 33%, respectively.

The Company will recognize potential interest and penalties related to income tax positions as a component of the provision for income taxes in the statements of operations in any future periods in which the Company must record such a liability. Since the Company has not recorded a liability at June 30, 2011, no amount of interest or penalties were recorded in the statement of financial condition or the statement of operations. Accordingly, there was no impact on the Company’s effective tax rate for such items. The Company does anticipate an increase of approximately $500,000 in its unrecognized tax benefits related to certain credit carryforwards anticipated to be generated within the next 12 months. The benefit of such items will be recorded through its statement of operations when recognized.

Acquisition

3.   Acquisition

On July 28, 2010, the Company acquired AlliedPath, Inc. AlliedPath is a high complexity CLIA-certified molecular pathology laboratory offering differentiated, high value molecular diagnostic services in the rapidly growing field of personalized medicine. Pursuant to the terms of the merger agreement dated July 26, 2010, the Company acquired all the issued and outstanding stock of AlliedPath for an amount in cash equal to $4.6 million less certain indebtedness existing at the closing, with an additional earn-out of up to $1.3 million subject to the achievement of specific sales and earnings targets through December 2013. We did not assume any outstanding options or warrants of AlliedPath in connection with the acquisition. AlliedPath is now called Arista Molecular, Inc. (“Arista”) and operates under the Personalized Medicine reporting segment of the consolidated financial statements.

Through the acquisition of Arista, the Company seeks to achieve the following goals:

•  to expand beyond its initial molecular pathology test menu by adding other molecular panels, flow cytometry for the detection and monitoring of leukemia and lymphoma, FISH testing, and proprietary new tests based on the Company’s NADiA technology platform;

•  to have better control of all aspects of the commercial operations of the NADiA platform, starting with NADiA ProsVue;

•  to enable the acceleration of the development efforts of the NADiA technology product pipeline; and

•  to enter the attractive personalized medicine market due to its significant growth potential.

The aggregate consideration paid for the acquisition of Arista was as follows:

	(In thousands)
Cash	$	4,584
Fair value of contingent consideration		1,210
Total purchase price	$	5,794

The aggregate consideration shown above reflects a $46,000 return of purchase price recorded during the six months ended June 30, 2011 (see Note 2, Goodwill and Intangible Assets).

The following table summarizes the estimated fair values of assets acquired and liabilities assumed as of July 28, 2010.

	(In thousands)
Current assets	$	74
Property and equipment		523
Core technology		3,090
CLIA License		1,604
Customer relationships		6
Non-compete agreements		100
Goodwill		1,461
Other assets		31
Current liabilities		(316	)
Lease obligations		(178	)
Other liabilities		(61	)
Deferred tax liability, net		(540	)
Total purchase price	$	5,794

In determining the purchase price allocation, the Company considered, among other factors, historical demand for products, estimates of future demand for those services, customer relationships, the revenue generating potential of core technology, the assets’ useful lives, and agreements not to compete. The market, income and cost approaches were used to determine fair values of these intangibles. The rate used to discount the net cash flows to their present value was a 16.5% weighted average cost of capital for the business as a whole, and from 16.5% to 17.5% for the individual intangible assets depending on the risk associated with the asset’s potential to generate revenues and its projected remaining useful economic life. The weighted average cost of capital was determined after consideration of market rates of return on debt and equity capital of comparable companies, the weighted average return on invested capital and the risk associated with achieving forecasted sales related to technology and assets acquired. The fair value of the contingent consideration was determined considering the probability of payout and using a 3% discount rate.

Subsequent changes in the fair value of the contingent consideration are recognized as a gain or loss on revaluation of contingent consideration within operating expenses in the Company’s consolidated statement of operations. The Company considers the changes in the fair value of contingent consideration obligation at each reporting date based on changes in discount rates, timing and amount of revenue estimates and changes in probability assumptions with respect to the probability of achieving the obligations. Accretion expense related to the increase in net present value of the contingent liability is included in interest expense for the period. As a result of significant revenue shortfalls at Arista relative to previous projections for the three months ended March 31, 2011, sales projections for Arista were significantly reduced for all future periods. The revised forecast projected revenues are significantly below earn-out targets for all three years covered by the earn-out period. Management thus determined that the fair value contingent consideration obligation was zero, which resulted in a decrease of $1.2 million from December 31, 2010 to March 31, 2011. Consequently the Company recognized a gain on revaluation of contingent consideration for the six months ended June 30, 2011 (recorded in March 2011). As of June 30, 2011, the fair value of the contingent consideration remains zero.

Property and equipment net book value was evaluated at approximately fair value on the acquisition date due to the nature and relative age of the assets acquired.

Acquired property and equipment are being depreciated on a straight-line basis with estimated remaining useful lives ranging from 1 year to 5 years. Intangible assets except the CLIA license are being amortized on a straight-line basis with estimated remaining useful lives ranging from 3 years to 15 years reflecting the expected future value. The CLIA license is considered to have an indefinite useful life. The purchase was structured as a stock purchase therefore the value assigned to the core technology, CLIA license, customers relationships, non-compete agreements and goodwill is not deductible for tax purposes.

The following table summarizes unaudited pro forma financial information assuming the acquisition of Arista had occurred in the corresponding period of the fiscal year immediately preceding the acquisition. This unaudited pro forma financial information does not necessarily represent what would have occurred if the transaction had taken place on January 1, 2009 (the beginning of the year prior to the acquisition) and should not be taken as representative of the Company’s future consolidated results of operations or financial position.

On November 22, 2010, the Company acquired the assets of a multi-purpose, bench-top instrument platform for automating highly repetitive, manual laboratory protocols for FISH (fluorescence in-situ hybridization) testing and other slide-based cytogenetic applications. The product acquisition is a natural extension to the successful ThermoBrite^® DNA Hybridization System and in line with the Company’s entry into personalized medicine with emphasis on cancer diagnostics. The product prototypes and proprietary technology assets were purchased for $3.2 million in cash from BioMicro Systems, Inc. The new product platform will be integrated into the Iris Sample Processing Division and it is expected to position IRIS as a major competitor in the high growth cytogenetic instrumentation market. This acquisition was recorded as an acquisition of assets determined not to be a business, since no workforce nor strategic management, operational or resource management processes were included in the purchase.

The purchase price of $3.2 million plus related asset acquisition costs of $94,000 was allocated as follows: $3.2 million to core technology, recorded in intangible assets, and $99,000 to property and equipment on the Company’s consolidated balance sheet as of June 30, 2011. The purchase price allocation was based on estimates and available information. Although BioMicro Systems built and tested a working prototype, which proved the technical feasibility of the base technology, several elements of this technology platform require continued development in order to reach salability for its stated purpose. Once development is completed, a useful life for the core technology will be determined and the core technology will be amortized over the useful life determined at that time.

The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The Company evaluated subsequent events through the date the financial statements were issued.

On July 22, 2011, the Company terminated its then existing credit facility and replaced it with a new credit facility entered into on July 27, 2011 with JPMorgan Chase Bank, N.A., as administrative agent for certain lenders. The credit facility provides for borrowings of up to $15 million pursuant to revolving loans, acquired participations in letters of credit and swingline loans. The Company has not borrowed any amounts under the credit facility. All amounts under the revolving loans become due and payable on July 31, 2013. The credit facility has variable interest rates, which will change from time to time based on changes to either the applicable LIBOR rate or the lender’s prime rate. Interest is generally payable monthly in arrears. The Company’s obligations under this credit facility are secured by a lien on substantially all of the Company’s assets and those of its domestic subsidiaries. The credit facility contains several performance covenants, limitations on additional indebtedness, and customary default provisions, and all outstanding obligations under the facility may become immediately due and payable in the event of the Company's default.

Our leases are primarily to customers in the health care industry or to governments. We assess credit risk for all of our customers including those who lease equipment. Credit risk is assessed using an internally developed model which incorporates credit scores from third party providers and our own custom risk ratings and is updated on a quarterly basis. The external credit scores are developed based on the customer’s historical payment patterns and an overall assessment of the likelihood of delinquent payments. Our internal ratings are weighted based on company size, years in business, and other credit related factors (i.e. profitability, cash flow, liquidity, tangible net worth, etc.). Any one of the following factors may result in a customer being classified as high risk: i) the customer has a history of late payments; ii) the customer has open lawsuits, liens or judgments; and iii) the customer has been in business less than three years. Our lease receivables are collateralized by the equipment’s fair value, which mitigates our credit risk. The following table presents the risk profile by creditworthiness category of our sales-type lease receivables at June 30, 2011:

	(In thousands)
Low risk	$	13,891
Moderate risk		820
High Risk		656
	$	15,367

The balance of the allowance for uncollectible accounts for our sales-type leases was zero as of June 30, 2011. We determine the adequacy of our allowance for uncollectible accounts for sales-type leases based on an analysis of historical write-offs. There have been no write-offs of sales-type lease receivables for the three or six months ended June 30, 2011 or 2010. As of June 30, 2011, the amount of sales-type leases which were past due was not significant and there were no impaired sales-type leases. Accordingly, there was no material risk of default with respect to sales-type leases as of June 30, 2011.
