NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared by Luminex Corporation (the “Company” or “Luminex”) in accordance with United States generally accepted accounting principles for interim financial information and the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles for complete financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring entries) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

The Company has two segments for financial reporting purposes: the technology and strategic partnerships (“TSP”) segment and the assays and related products (“ARP”) segment. See Note 9 — Segment Information.

NOTE 2 — BUSINESS COMBINATIONS

On June 27, 2011, the Company completed its acquisition of 100% of the outstanding shares of EraGen Biosciences, Inc., now known as Luminex Madison, or LMA, a privately-held molecular diagnostic company in Madison, Wisconsin, which was founded in 1999, for the aggregate cash purchase price of $34 million. The results of operations for LMA have been included in the Company’s consolidated financial statements from the date of acquisition as part of the Company’s ARP segment. $5.6 million of the cash purchase price was deposited in escrow as security for breaches of representations and warranties and certain other expressly enumerated matters and to satisfy any post-closing adjustments. $150,000 of this escrow was released to the seller in the third quarter of 2011 after the closing balance sheet was finalized, $1 million of this escrow was released to a licensor of LMA to fund an indemnification claim in the first quarter of 2012 related to a fee due pursuant to a sublicense agreement, and $944,000 of this escrow was released to former shareholders of EraGen Biosciences, Inc. and certain other individuals in the third quarter of 2012 at the conclusion of the one year initial general claims escrow period.

NOTE 3 — INVESTMENTS

Marketable Securities

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase and reevaluates such determinations at each balance sheet date. Marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses recognized in earnings. Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost, which approximates the fair value of these investments. Debt securities for which the Company does not have the intent or ability to hold to maturity are classified as available-for-sale. Debt and marketable equity securities not classified as held-to-maturity or as trading are classified as available-for-sale, and are carried at fair market value, with the unrealized gains and losses included in the determination of comprehensive income and reported in stockholders’ equity. As of June 30, 2012 and December 31, 2011, all of the Company’s marketable securities are classified as available for sale. Marketable securities are recorded as either short-term or long-term on the balance sheet based on contractual maturity date. The fair value of all securities is determined by quoted market prices, market interest rates inputs, or other than quoted prices that are observable either directly or indirectly (as of the end of the reporting period). Declines in fair value below the Company’s carrying value deemed to be other than temporary are charged against net earnings.

Total available-for-sale securities	$	87,203	$	54	$	(12	)	$	87,245

There were $6 million and $0 in proceeds from the sales of available-for-sale securities during the three months ended June 30, 2012 and 2011, respectively. Realized gains and losses on sales of investments are determined using the specific identification method. Realized gains and losses are included in other income (expense) in the Consolidated Statement of Comprehensive Income. Net unrealized holding gains and losses on available-for-sale securities of $14,000, net of $10,000 of tax expense, on available-for-sale securities, have been included in accumulated other comprehensive gain (loss) as of June 30, 2012. All of the Company’s available-for-sale securities with gross unrealized losses as of June 30, 2012 and December 31, 2011 had been in a loss position for less than 12 months.

The estimated fair value of available-for-sale debt securities at June 30, 2012 and December 31, 2011, by contractual maturity, was as follows (in thousands):

	Estimated Fair Value
	June 30, 2012		December 31, 2011
Due in one year or less	$	23,150	$	42,574
Due after one year through two years		5,997		6,151
	$	29,147	$	48,725

Table of Contents

Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Non-Marketable Securities and Other-Than-Temporary Impairment

In the second quarter of 2010, the Company invested $2.0 million in a private company based in the U.S. In the first quarter of 2011, the Company invested an additional $2.0 million in the same private company. This minority investment in the private company is included at cost in other long-term assets on the Company’s Condensed Consolidated Balance Sheets as the Company does not have significant influence over the investee, owns less than 20% of the voting equity and the investee is not publicly traded. The Company regularly evaluates the carrying value of this cost-method investment for impairment and whether any events or circumstances are identified that would significantly harm the fair value of the investment. The primary indicators the Company utilizes to identify these events and circumstances are the investee’s ability to remain in business, such as the investee’s liquidity and rate of cash use, and the investee’s ability to secure additional funding and the value of that additional funding. In the event a decline in fair value is judged to be other-than-temporary, the Company will record an other-than-temporary impairment charge in other income, net in the Consolidated Statements of Comprehensive Income.

NOTE 4 — INVENTORIES, NET

Inventory is stated at the lower of cost or market, with cost determined according to the standard cost method. Inventory consisted of the following (in thousands):

	June 30, 2012		December 31, 2011
Parts and supplies	$	14,397	$	12,382
Work-in-progress		4,867		6,829
Finished goods		7,040		5,368
	$	26,304	$	24,579

NOTE 5 — FAIR VALUE MEASUREMENT

The Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The ASC describes a fair value hierarchy based on the following three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company determines the fair value of its investment portfolio assets by obtaining non-binding market prices from its third-party portfolio managers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. The Company regularly evaluates the carrying value of the Level 3, cost-method investment for impairment and whether any events or circumstances are identified that would significantly harm the fair value of the investment. The primary indicators the Company utilizes to identify these events and circumstances are the investee’s ability to remain in business, such as the investee’s liquidity and rate of cash use, and the investee’s ability to secure additional funding and the value of that additional funding. There were no transfers between Level 1, Level 2, or Level 3 measurements for the three month period ending June 30, 2012.

Table of Contents

The Company’s long-term debt is classified as a Level 3 instrument and the Company has used a discounted cash flow (“DCF”) model to determine the estimated fair value for disclosure purposes as of June 30, 2012 and December 31, 2011, which does not equal its carrying value on the Consolidated Balance Sheet. The assumptions used in preparing the DCF model include estimates for (i) the amount and timing of future interest and principal payments and (ii) the rate of return indicative of the investment risk in the ownership of the TPC debt. In making these assumptions, the Company considered relevant factors including the likely timing of principal repayments and the probability of full repayment considering the timing of royalty payments based upon total revenue.

The following table represents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2012 and December 31, 2011 (in thousands):

NOTE 6 — GOODWILL AND OTHER INTANGIBLE ASSETS

On June 27, 2011, the Company completed the acquisition of LMA. As a result, the Company recorded approximately $0.5 million of goodwill and $20.0 million of other identifiable intangible assets. For impairment testing purposes, the Company has assigned all of the LMA goodwill to the ARP segment. This goodwill is not expected to be deductible for tax purposes.

The changes in the carrying amount of the Company’s goodwill during the period are as follows (in thousands):

	June 30, 2012			December 31, 2011
Balance at beginning of year	$	42,763		$	42,250

NOTE 7 — EARNINGS PER SHARE

A reconciliation of the denominators used in computing per share net income, or EPS, is as follows (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Numerator:
Net income	$	2,952	$	4,643	$	6,479	$	9,104

Denominator:
Denominator for basic net income per share - weighted average common stock outstanding		41,064		41,262		40,992		41,251

Effect of dilutive securities: stock options and awards		1,335		1,184		1,254		1,147

Denominator for diluted net income per share - weighted average shares outstanding - diluted		42,399		42,446		42,246		42,398

Basic net income per share	$	0.07	$	0.11	$	0.16	$	0.22
Diluted net income per share	$	0.07	$	0.11	$	0.15	$	0.21

Basic net income per share is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Restricted stock (consisting of restricted stock awards, or RSAs, and restricted stock units, or RSUs) and stock options to acquire approximately zero and 35,000 shares for the three months ended June 30, 2012 and 2011, respectively, and zero and 35,000 shares for the six months ended June 30, 2012 and 2011, respectively, were excluded from the computations of diluted EPS because the effect of including those RSAs, RSUs, and stock options would have been anti-dilutive.

NOTE 9 — SEGMENT INFORMATION

Management has determined that the Company has two segments for financial reporting purposes: the technology and strategic partnerships segment and the assays and related products segment. The accounting principles 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 year ended December 31, 2011.

Intersegment sales are recorded at fixed prices that approximate the prices charged to third party strategic partners and are not a measure of segment operating earnings. Intersegment sales of approximately $3.3 million and $1.9 million for the quarters ending June 30, 2012 and 2011, and $5.7 million and $4.4 million for the six months ended June 30, 2012 and 2011, respectively, have been eliminated upon consolidation. Following is selected segment information for and as of the periods indicated (in thousands).

	Three Months Ended June 30, 2012						Three Months Ended June 30, 2011

NOTE 10 — ACCRUED WARRANTY COSTS

Sales of certain of the Company's systems are subject to a warranty. System warranties typically extend for a period of 12 months from the date of installation not to exceed 24 months from the date of shipment. The Company estimates the amount of warranty claims on sold products that may be incurred based on current and historical data. The actual warranty expense could differ from the estimates made by the Company based on product performance. Warranty expenses are evaluated and adjusted periodically.

The following table summarizes the changes in the warranty accrual (in thousands):


Accrued warranty costs at December 31, 2011	$	681
Warranty expenses		(523	)
Accrual for warranty costs		544
Accrued warranty costs at June 30, 2012	$	702

NOTE 11 — INCOME TAXES

At the end of each interim reporting period, an estimate is made of the effective tax rate expected to be applicable for the full year. The estimated full year’s effective tax rate is used to determine the income tax rate for each applicable interim reporting period. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. The effective tax rate for the six months ended June 30, 2012 was 46.32%, including amounts recorded for discrete events. This differs from the statutory rate of 35% primarily because of the worldwide mix of consolidated earnings before taxes and an assessment regarding the realizability of the Company’s deferred tax assets. The Company’s tax expense reflects the full Federal, various state, and foreign blended statutory rates. The Company is utilizing its net operating losses in the U.S. and Canada; therefore cash taxes to be paid are expected to be in the range of 5-10% of pre-tax book income.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, Australia, Canada, China, Japan, the Netherlands, and various states. Due to net operating losses, the U.S. tax returns dating back to 1996 can still be reviewed by the taxing authorities. With respect to Canada, tax returns dating back to 2002 can still be reviewed by the authorities. The Company recorded no liabilities associated with its uncertain tax positions in the first two quarters of 2012. No other material changes to this liability are expected within the next 12 months. For the six months ended June 30, 2012, there were no material changes to the total amount of unrecognized tax benefits. The Company recognizes interest and penalties related to uncertain tax positions in the provision for income taxes.

NOTE 12 — RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amended guidance eliminated one of the presentation options provided by accounting principles generally accepted in the United States of America (“U.S. GAAP”) which was to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. In addition, it gave an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance was effective for reporting periods beginning after December 15, 2011 and has been applied retrospectively. The impact of adoption on the Company’s financial position and results of operations was not material.

In September 2011, the FASB issued amendments to the goodwill impairment guidance which provides an option for companies to use a qualitative approach to test goodwill for impairment if certain conditions are met. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 (early adoption is permitted). The Company early adopted the amendments in connection with the performance of the Company’s annual goodwill impairment test. The impact of adoption on the Company’s financial position and results of operations was not material.

NOTE 13 — SUBSEQUENT EVENTS

On July 11, 2012, the Company completed its acquisition of GenturaDx, Inc., a British Virgin Islands corporation with operations in Hayward, California (“GenturaDx”), pursuant to the terms of an Agreement and Plan of Merger, dated July 9, 2012, by and among Luminex, Grouper Merger Sub, Inc., a British Virgin Islands corporation and a wholly-owned subsidiary of Luminex (“Merger Sub”), GenturaDx, and a representative of the stockholders and lenders of GenturaDx (the “Agreement”). Pursuant to the terms of the Agreement, Merger Sub merged with and into GenturaDx and GenturaDx continued as the surviving corporation as a wholly-owned subsidiary of Luminex (the “Merger”).

Under the terms of the Agreement, the Company acquired all of the outstanding capital stock of GenturaDx in exchange for approximately $50 million cash consideration, subject to working capital adjustments, plus (i) $3 million in consideration contingent upon achieving certain future development and regulatory milestones by December 31, 2013, (ii) up to $7 million in consideration contingent upon achieving certain future development and regulatory milestones by June 30, 2014 and (iii) additional consideration contingent upon acquired products exceeding certain revenue thresholds in each of 2013, 2014 and 2015. An amount of $8 million of the upfront consideration was deposited in escrow as security for potential indemnity claims and certain other expressly enumerated matters and $100,000 was deposited in escrow to satisfy, in part, any post-closing adjustments relating to GenturaDx’s working capital balance at closing. Additionally, up to 30% of the milestone payments are subject to certain set-off rights of the Company for indemnification claims under the Agreement. The remainder of the upfront consideration was used to repay GenturaDx’s indebtedness and other expenses. The Company’s acquisition of GenturaDx was funded by the use of cash on hand.

Segment Information

Luminex has two reportable segments: the technology and strategic partnerships segment and the assays and related products segment. The TSP segment, which is our base business, consists of system sales to partners, raw bead sales, royalties, service and support of the technology, and other miscellaneous items. The ARP segment is primarily involved in the development and sale of assays on xMAP® technology for use on Luminex’s installed base of systems, and the MultiCode® technology obtained with our June 2011 acquisition of EraGen Biosciences, Inc., now known as Luminex Madison, or LMA.

OVERVIEW

We develop, manufacture and sell proprietary biological testing technologies and products with applications throughout the life sciences and diagnostics industries. These industries depend on a broad range of tests, called bioassays, to perform diagnostic tests and conduct life science research.

Our xMAP (Multi-Analyte Profiling) technology, an open architecture, multiplexing technology, allows simultaneous analysis of up to 500 bioassays from a small sample volume, typically a single drop of fluid, by reading biological tests on the surface of microscopic polystyrene beads called microspheres. xMAP technology combines this miniaturized liquid array bioassay capability with small lasers, light emitting diodes (LEDs), digital signal processors, photo detectors, charge-coupled device (CCD) imaging and proprietary software to create a system offering advantages in speed, precision, flexibility and cost. Our xMAP technology is currently being used within various segments of the life sciences industry which includes the fields of drug discovery and development, and for clinical diagnostics, genetic analysis, bio-defense, food safety and biomedical research. In addition to our xMAP technology, our other offerings include our proprietary MultiCode® technology, used for real-time polymerase chain reaction (PCR) and multiplexed PCR assays, as well as automation and robotics in the field of dry sample handling.

Our xTAG® and MultiCode® assay chemistries are proprietary technologies primarily used to detect analytes for human genetic testing and infectious disease testing. Our MultiCode technology makes use of a DNA base pair (isoC:isoG) not found in nature. This synthetic third base pair is used in the creation of both multiplex PCR assays (MultiCode-PLx) and low-plex, real-time PCR assays (MultiCode-RTx). Currently, most of our MultiCode assay and reagent revenue is based on products using our MultiCode-RTx technology. The xTAG and MultiCode chemistries are both compatible with our xMAP technology, and the MultiCode chemistry is also compatible with low-plex real-time PCR platforms available from a variety of vendors.

Table of Contents

Our end user customers and partners, which include laboratory professionals performing research, clinical laboratories performing tests on patients as ordered by a physician and other laboratories, have a fundamental need to perform high quality testing as efficiently as possible. Luminex has adopted a business model built, in part, around strategic partnerships. We have licensed our xMAP technology to partner companies, which in turn develop products that incorporate the xMAP technology into products that our partners sell to end users. We develop and manufacture the proprietary xMAP laboratory instrumentation and the proprietary xMAP microspheres and sell these products to our partners. Our partners then sell xMAP instrumentation and xMAP-based reagent consumable products, which run on the instrumentation, to the end user laboratory. As of June 30, 2012, Luminex had approximately 66 strategic partners and these partners have purchased from Luminex approximately 9,160 xMAP-based multiplexing analyzer systems. Of the 66 strategic partners, 45 have released commercialized reagent-based products utilizing our technology.

Luminex has several forms of revenue that result from our business model:

·	System revenue is generated from the sale of our xMAP multiplexing analyzers and peripherals and automated punching instruments.

Consumable revenue is generated from the sale of our dyed polystyrene microspheres and sheath fluid. Our larger commercial and development partners often purchase these consumables in bulk to minimize the number of incoming qualification events and to allow for longer development and production runs.

Royalty revenue is generated when a partner sells our proprietary microspheres to an end user, a partner sells a kit incorporating our proprietary technologies to an end user, or a partner utilizes a kit incorporating our proprietary technologies to provide a testing result to a user. End users can be facilities such as testing labs, development facilities and research facilities that buy prepared kits and have specific testing needs or testing service companies that provide assay results to pharmaceutical research companies or physicians.

·	Assay revenue is generated from the sale of our kits, which are a combination of chemical and biological reagents, and our proprietary technologies used to perform diagnostic and research assays on samples.

Service revenue is generated when a partner or other owner of a system purchases a service contract from us after the standard warranty has expired or pays us for our time and materials to service instruments. Service contract revenue is amortized over the life of the contract and the costs associated with those contracts are recognized as incurred.

·	Other revenue consists of items such as training, shipping, parts sales, license revenue, grant revenue, contract research and development fees, milestone revenue and other items that individually amount to less than 5% of total revenue.

Second Quarter 2012 Highlights

·	Consolidated revenue was $48.3 million for the quarter ended June 30, 2012, representing a 1% increase over revenue for the second quarter of 2011.

·	Shipments of 278 multiplexing analyzers that included 167 MAGPIX systems, resulting in cumulative life-to-date multiplexing analyzer shipments of 9,162, up 12% from a year ago.

·	Assay revenue was $17.5 million, an 89% increase over the second quarter of 2011.

·	Operating expenses were $27.9 million for the quarter ended June 30, 2012, an increase of $2.9 million over the quarter ended June 30, 2011, including $0.9 million of incremental operating expenses from LMA.

·	Received CE marking of both the xMAP NeoPlex4® Assay and NeoPlex® System in April, 2012. This system changes the way newborn screening is performed, providing four assays from one blood spot punch, reducing sample requirements and improving laboratory efficiency.

Acquisition of GenturaDx on July 11, 2012

Subsequent to quarter end, we acquired privately-held GenturaDx, a molecular diagnostics company focused on making nucleic acid testing both affordable and practical for any laboratory. Under the terms of the Agreement, we acquired all of the outstanding capital stock of GenturaDx in exchange for approximately $50 million cash consideration, subject to working capital adjustments, plus (i) $3 million in consideration contingent upon achieving certain future development and regulatory milestones by December 31, 2013, (ii) up to $7 million in consideration contingent upon achieving certain future development and regulatory milestones by June 30, 2014 and (iii) additional consideration contingent upon acquired products exceeding certain revenue thresholds in each of 2013, 2014 and 2015. The acquisition was funded by the use of cash on hand.

GenturaDx is in late stage development of a fully integrated, highly automated, real-time PCR system that employs a single-use cassette for sample-to-answer workflow. This new system will integrate with our MultiCode-RTx chemistry to make rapid, high-quality molecular diagnostics accessible to hospitals and patients worldwide. GenturaDx's patented cartridge design provides automated sample extraction, amplification and detection thereby improving testing throughput, while reducing hands on time, turnaround times and sample handling. Luminex anticipates commercial availability of a variety of assays for use with this system by early 2014.

Consumables Sales and Royalty Revenue Trends

We have experienced significant fluctuations in consumable revenue over the past two years. Overall, the fluctuations manifested themselves through periodic changes in volume from our largest bulk purchasing partners. From the second quarter of 2010 through the second quarter of 2012, we had quarterly bulk purchases ranging from $7.0 million to $16.1 million and representing between 75% and 88% of total consumable revenue. We expect these fluctuations to continue as the ordering patterns of our largest bulk purchasing partners remains variable. Even though we experience variability in consumable revenue, the key indicator of the success of our partners’ commercialization efforts is the rising level of reported royalty bearing sales during the past several years which have increased at a compound annual growth rate of 8% since the first quarter of 2010.

Future Operations

We expect our areas of focus over the next twelve months to be:

·	maintenance and improvement of our existing products and the timely development, completion and successful commercial launch of our pipeline products;

·	commercialization, regulatory clearance and market adoption of output from the ARP segment, including the NeoPlex System, NeoPlex4 Assay, CYP2C19, Gastrointestinal Pathogen Panel (“GPP”), and the related clearance of our MAGPIX and FM3D instruments;

·	the expansion and enhancement of our installed base and our market position within our identified target market segments;

·	the effect of the ongoing uncertainty in global finance markets and changes in government funding on planned purchases by end users;

·	the continued adoption and development of partner products incorporating Luminex technology through effective partner management; and

·	development of the next generation sample-to-answer platform for our MultiCode RTx technology.

We anticipate continued revenue concentration in our higher margin items (assays, consumables and royalties) contributing to favorable, but variable, gross margin percentages. Additionally, we believe that a sustained investment in research and development is necessary in order to meet the needs of our marketplace and provide a sustainable new product pipeline. We may experience volatility in research and development expenses as a percentage of revenue on a quarterly basis.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles for interim financial statements. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Estimates and assumptions are reviewed periodically. Actual results may differ from these estimates under different assumptions or conditions.

Management believes there have been no significant changes during the quarter ended June 30, 2012 to the items that we disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2011 10-K.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2012 COMPARED TO THREE MONTHS ENDED JUNE 30, 2011

Selected consolidated financial data for the three months ended June 30, 2012 and 2011 is as follows (dollars in thousands):

	Three Months Ended June 30,
	2012			2011			Variance			Variance (%)
Revenue	$	48,273		$	47,638		$	635			1	%
Gross profit	$	34,412		$	33,826			586			2	%
Gross profit margin percentage		71	%		71	%		0	%		N/A
Operating expenses	$	27,926		$	25,029			2,897			12	%
Income from operations	$	6,486		$	8,797			(2,311	)		-26	%

Total revenue increased by 1% to $48.3 million for the three months ended June 30, 2012 from $47.6 million for the comparable period in 2011. The increase was primarily attributable to an increase in assay revenue, partially offset by a decline in consumable sales. The increase in assay revenue of $8.2 million was driven primarily by the inclusion of sales of our LMA assay products in the three months ended June 30, 2012 as a result of the acquisition of LMA on June 27, 2011. The increase in assay revenue was partially offset by a decrease in consumable sales of $7.6 million, which resulted primarily from volume decreases in bulk purchases from one of our partners. System revenue decreased from $9.1 million in the second quarter of 2011 to $8.4 million in the second quarter of 2012. We sold 278 multiplexing analyzers in the second quarter of 2012, which included 167 of our MAGPIX systems as compared to 248 multiplexing analyzers sold for the corresponding prior year period, which included 62 MAGPIX systems, bringing total multiplexing analyzer sales since inception to 9,162 as of June 30, 2012. Also included in second quarter system revenue were sales of 18 automated punching systems compared to 44 in the prior year, a decrease that was primarily the result of the cyclical nature of activities in the world surrounding major forensic events. Irrespective of the increase in the number of multiplexing analyzers placements relative to the prior year, system revenue declined primarily as a result of two factors: (i) a shift towards our lower priced MAGPIX systems and (ii) a decrease in the number of automated punching systems placed.

A breakdown of revenue for the three months ended June 30, 2012 and 2011 is as follows (dollars in thousands):

	Three Months Ended June 30,
	2012		2011		Variance			Variance (%)
System sales	$	8,386	$	9,135	$	(749	)		-8	%
Consumable sales		10,802		18,397		(7,595	)		-41	%
Royalty revenue		7,715		7,412		303			4	%
Assay revenue		17,510		9,261		8,249			89	%

	$	48,273	$	47,638	$	635			1	%

We continue to experience revenue concentration in a limited number of strategic partners. Four customers accounted for 54% (20%, 15%, 10% and 9%, respectively) of consolidated total revenue in the second quarter of 2012. For comparative purposes, those same four customers accounted for 54% (7%, 28%, 10% and 9%, respectively) of total revenue in the second quarter of 2011.

Gross profit margin percentage remained constant at 71% for the second quarter of 2012 and 2011. Our gross profit margin percentage is highly dependent upon the mix of revenue components each quarter. Assay revenue increased to $17.5 million, or 36%, of total revenue for the second quarter of 2012 from $9.3 million, or 19% of total revenue for the quarter ended June 30, 2011. Consumable sales, a higher margin item, decreased from 39% of revenue in the second quarter of 2011 to 22% of revenue in the second quarter of 2012. The increase in assay revenue was driven primarily by our acquisition of LMA on June 27, 2011. We anticipate fluctuation in gross profit margin and related gross profit primarily as a result of variability in the percentage of revenue derived from each of our revenue streams and the seasonality effect inherent in our assay revenue. The increase in total operating expense dollars from $25.0 million, or 53% of revenue, to $27.9 million, or 58% of revenue is primarily attributable to $0.9 million in incremental operating expenses from LMA, growth in our marketing efforts to support our global initiatives, additional personnel costs and rent, utility and depreciation expenses associated with the addition of employees and expansion of our facilities and technology infrastructure.

Revenue. Total revenue for our TSP segment decreased by 18% to $29.6 million for the three months ended June 30, 2012 from $36.2 million for the comparable period in 2011. The decrease in revenue was primarily attributable to a decrease of $7.5 million in consumable revenue attributable to volume decreases in bulk purchases from one of our partners.

Three customers accounted for 56% of total TSP segment revenue in the second quarter of 2012 (25%, 16% and 15%, respectively). For comparative purposes, these same three customers accounted for 62% of total TSP segment revenue (37%, 13% and 12%, respectively) in the second quarter of 2011. No other customer accounted for more than 10% of total TSP segment revenue during those periods.

System and peripheral component sales increased by 4% to $7.7 million for the three months ended June 30, 2012 from $7.4 million for the comparable period of 2011. The TSP segment sold 277 of the 278 total multiplexing analyzer sales, which includes 167 MAGPIX systems, in the three months ended June 30, 2012 as compared to 245 multiplexing analyzers, which included 62 MAGPIX systems, in the same prior year period. The increase in system revenue is the result of an increase in the number of multiplexing analyzer placements relative to the prior year, offset by a shift towards our lower priced MAGPIX systems. For the three months ended June 30, 2012, two of our partners accounted for 207 analyzers, or 75% of total TSP segment multiplexing analyzers sold for the period. The top five partners accounted for 245 analyzers, or 88%, of total TSP segment systems sold in the three months ended June 30, 2012.

Consumable sales, comprised of microspheres and sheath fluid, decreased 41% to $10.7 million for the three months ended June 30, 2012 from $18.3 million for the three months ended June 30, 2011. During the three months ended June 30, 2012, we had 15 bulk purchases of consumables totaling approximately $8.1 million (76% of total TSP segment consumable revenue), ranging from $0.1 million to $3.5 million, as compared with 14 bulk purchases totaling approximately $16.1 million (88% of total TSP segment consumable revenue), in the three months ended June 30, 2011. A bulk purchase is defined as the purchase of $100,000 or more of consumables in a quarter. The decrease in consumable revenue was primarily attributable to volume decreases in bulk purchases from one of our partners as a result of a change in the timing of their consumable needs due to a modification to their inventory management practices in the prior year. We expect these fluctuations to continue as the ordering pattern of our largest bulk purchasing partner varies due to their efforts to minimize the number of incoming qualification events, control inventory, and allow for longer development and production runs. Partners who reported royalty bearing sales accounted for $7.5 million, or 70%, of total consumable sales for the three months ended June 30, 2012.

Royalty revenue, which results when our partners sell products or services incorporating our technology, increased by 2% to $7.6 million for the three months ended June 30, 2012 compared with $7.4 million for the three months ended June 30, 2011. Our partners’ end user sales may reflect volatility from quarter to quarter and therefore, that same volatility is reflected in our reported royalty revenues on a quarterly basis. Additionally, we expect modest fluctuations in the number of commercial partners submitting royalties quarter to quarter based upon the varying contractual terms, consolidations among partners, differing reporting and payment requirements, and the addition of new partners. For the three months ended June 30, 2012, we had 39 commercial partners submitting royalties as compared to 41 for the three months ended June 30, 2011. One of our partners reported royalties totaling approximately $3.4 million, or 45%, of total royalties for the quarter ended June 30, 2012 compared to $3.0 million, or 40%, for the quarter ended June 30, 2011. Two other customers reported royalties totaling approximately $1.8 million, or 24%, of total TSP royalty revenue (13% and 11%, respectively) for the quarter ended June 30, 2012. No other customer accounted for more than 10% of total royalty revenue for the quarter ended June 30, 2012. For comparative purposes, these same two customers accounted for approximately $1.7 million, or 23% (12% and 11%, respectively), of total TSP royalty revenue in the second quarter of 2011. Royalty revenues were comprised of 73% from diagnostic partners and 27% from life science research partners. Total TSP royalty bearing sales reported to us by our partners were over $102 million for the quarter ended June 30, 2012, compared with over $97 million for the quarter ended June 30, 2011.

Service revenue, comprised of extended warranty contracts earned ratably over the term of a contract and fees for services performed on instruments, increased by 6% to $1.8 million for the second quarter of 2012 from $1.7 million for the second quarter of 2011. This increase is attributable to increased penetration of the expanded installed base. At June 30, 2012 and 2011, we had 1,374 and 1,205 Luminex systems, respectively, covered under extended service agreements.

Other revenues, comprised of training revenue, shipping revenue, miscellaneous part sales, amortized license fees, reagent sales, and grant revenue, increased by 22% to $1.7 million for the three months ended June 30, 2012 from $1.4 million for the three months ended June 30, 2011. This increase is primarily the result of an increase in grant revenue and license fees.

Gross profit margin. The gross profit margin percentage for the TSP segment decreased to 68% for the three months ended June 30, 2012 compared to 74% for the three months ended June 30, 2011. The decrease in gross profit margin was primarily the result of the decrease in consumable sales, a higher margin item, from 50% of revenue in the second quarter of 2011 to 36% of revenue in the second quarter of 2012.

Research and development expense. Research and development expenses for the TSP segment increased to $3.5 million, or 12% of TSP segment revenue, for the three months ended June 30, 2012 compared to $3.2 million, or 9% of TSP segment revenue, for the comparable period in 2011. The focus of our TSP segment research and development activities, on continued refinement of our systems and software to meet the evolving needs of the marketplace including the addition of more automated solutions for assay performance, remains consistent with the prior year.

Selling, general and administrative expense. Selling, general and administrative expense for the TSP segment increased to $12.2 million, or 41% of TSP segment revenue for the three months ended June 30, 2012 from $12.1 million, or 34% of TSP segment revenue, for the comparable period in 2011.

Revenue. Total revenue for our ARP segment increased by 64% to $18.7 million for the three months ended June 30, 2012 from $11.4 million for the comparable period in 2011. The increase in revenue was predominantly attributable to an increase in assay revenue driven primarily by the inclusion of sales of our LMA assay products in the three months ended June 30, 2012 as a result of the acquisition of LMA on June 27, 2011. Our assay products are currently divided into two distinct categories; infectious disease testing and genetic testing, which represented 70% and 30% of total assay revenue in the second quarter of 2012 as compared to 44% and 56% in the second quarter of 2011, respectively. The top two customers, by revenue, accounted for 69% of total ARP segment revenue (49% and 20%, respectively) for the three months ended June 30, 2012 compared to 55% (29% and 26%, respectively) for the three months ended June 30, 2011. No other customer accounted for more than 10% of total ARP segment revenue during those periods. During the three months ended June 30, 2012, our ARP segment sold one multiplexing analyzer and 18 automated punching systems, compared to three multiplexing analyzers and 44 automated punching systems during the three months ended June 30, 2011. The decline in sales of automated punching systems is primarily the result of the cyclical nature of activities in the world surrounding major forensic events. Other revenue includes shipping revenue and training revenue.

Gross profit margin. The gross profit margin percentage for the ARP segment increased to 77% for the three months ended June 30, 2012 from 61% for the three months ended June 30, 2011. The increase in gross profit margin percentage was primarily attributable to increased sales of high margin assays from LMA, including a new OEM assay manufacturing agreement and the impact of fewer automated punching systems placed, which are a lower margin item.

Research and development expense. Research and development expenses for our ARP segment was $6.1 million and $4.7 million, for the three months ended June 30, 2012 and 2011, respectively. The increase in research and development expenses was primarily the result of increases in materials and additional personnel costs associated with the addition of employees resulting from increased activity related to product development, including clinical trials costs, together with the inclusion of $0.4 million of LMA’s research and development expenses in the second quarter of 2012 results. Notwithstanding the $1.4 million increase in research and development expenses, research and development expenses decreased as a percentage of ARP segment revenues from 42% for the three months ended June 30, 2012 to 33% for the three months ended June 30, 2012. Research and development employees and contract employees of the ARP segment increased to 115 at June 30, 2012 from 105 at June 30, 2011, primarily due to employees added by the acquisition of LMA.

Selling, general and administrative expense. Selling, general and administrative expenses, including the amortization of acquired intangibles, for the ARP segment were $6.1 million, or 33% of ARP segment revenue, for the three months ended June 30, 2012 compared to $4.9 million, or 43% of ARP segment revenue, for the three months ended June 30, 2011. The increase in selling, general, and administrative expenses is primarily due to the inclusion of LMA in the second quarter of 2012 results and the expansion of the life science and biodefense groups.

SIX MONTHS ENDED JUNE 30, 2012 COMPARED TO SIX MONTHS ENDED JUNE 30, 2011

Selected consolidated financial data for the six months ended June 30, 2012 and 2011 is as follows (dollars in thousands):

	Six Months Ended June 30,
	2012			2011			Variance			Variance (%)
Revenue	$	97,000		$	90,913		$	6,087			7	%

Income from operations	$	12,094		$	17,091			(4,997	)		-29	%

Total revenue increased by 7% to $97.0 million for the six months ended June 30, 2012 from $90.9 million for the comparable period in 2011. The increase was primarily attributable to an increase in assay revenue, partially offset by a decrease in consumable sales. The increase in assay revenue of $16.0 million was driven primarily by the inclusion of sales of our LMA assay products. The increase in assay revenue was partially offset by a decrease in consumable sales of $10.7 million, which resulted primarily from volume decreases in bulk purchases from one of our partners. System revenue decreased from $16.8 million in the first half of 2011 to $15.4 million in the first half of 2012. We sold 484 multiplexing analyzers in the first half of 2012, which included 222 of our MAGPIX systems as compared to 445 multiplexing analyzers sold for the corresponding prior year period, which included 100 MAGPIX systems, bringing total multiplexing analyzer sales since inception to 9,162 as of June 30, 2012. Also included in system revenue for the six months ended June 30, 2012 were sales of 31 automated punching systems compared to 78 in the prior year. Irrespective of the increase in the number of multiplexing analyzers placements relative to the prior year, system revenue declined primarily as a result of two factors: (i) a shift towards our lower priced MAGPIX systems and (ii) a decrease in the number of automated punching systems placed.

We continue to experience revenue concentration in a limited number of strategic partners. Four customers accounted for 52% (19%, 16%, 9% and 8%, respectively) of consolidated total revenue in the six months ended June 30, 2012. For comparative purposes, these same four customers accounted for 53% (8%, 28%, 8% and 9%, respectively) of total revenue in the six months ended June 30, 2011.

Gross profit margin percentage for the six months ended June 30, 2012 decreased to 70% from 71% for the comparable period in 2011. In spite of the decrease in gross profit margin percentage, gross profit increased to $68.2 million for the six months ended June 30, 2012, as compared to $64.6 million for the six months ended June 30, 2011. Our gross profit margin percentage is highly dependent upon the mix of revenue components each quarter. The decrease in gross profit margins was primarily the result of the decrease in consumable sales, a higher margin item, from 37% of revenue in the first half of 2011 to 23% of revenue in the first half of 2012. The decrease in consumable sales was offset by an increase in assay revenue, at a slightly lower gross profit margin. Assay revenue increased to $34.8 million, or 36% of total revenue, for the six months ended June 30, 2012 from $18.8 million, or 21% of total revenue, for the six months ended June 30, 2011. The increase in total operating expense dollars from $47.5 million, or 52% of revenue, to $56.1 million, or 58% of revenue, is primarily attributable to the acquisition of LMA in June of 2011, additional personnel costs associated with growth in our marketing efforts to support our global initiatives and expansion of our facilities and technology infrastructure. We anticipate continued fluctuation in gross profit margin and related gross profit primarily as a result of variability in the percentage of revenue derived from each of our revenue streams and the seasonality effect inherent in our assay revenue.

Revenue. Total revenue for our TSP segment decreased by 12% to $59.8 million for the six months ended June 30, 2012 from $68.1 million for the comparable period in 2011. The decrease in revenue was primarily attributable to a decrease of $10.7 million in consumable revenue attributable to volume decreases in bulk purchases from one of our partners offset by an increase in royalty revenue of $1.0 million.

Three customers accounted for 52% of total TSP segment revenue in the six months ended June 30, 2012 (25%, 14% and 13%, respectively). For comparative purposes, these same three customers accounted for 60% of total TSP segment revenue (38%, 11%, and 11%, respectively) in the six months ended June 30, 2011. No other customer accounted for more than 10% of total TSP segment revenue during those periods.

System and peripheral component sales increased by 1% to $14.0 million for the six months ended June 30, 2012 from $13.8 million for the comparable period of 2011. The TSP segment sold 475 of the 484 total multiplexing analyzer sales, which includes 222 MAGPIX systems, in the six months ended June 30, 2012 as compared to 438 multiplexing analyzers, which included 100 MAGPIX systems, in the same prior year period. The increase in system revenue is the result of an increase in the number of multiplexing analyzer placements relative to the prior year, offset by a shift towards our lower priced MAGPIX systems. For the six months ended June 30, 2012, two of our partners accounted for 315 analyzers, or 66% of total TSP segment multiplexing analyzers sold for the period. The top five partners accounted for 398 analyzers, or 84%, of total TSP segment systems sold in the six months ended June 30, 2012.

Consumable sales, comprised of microspheres and sheath fluid, decreased 32% to $22.6 million for the six months ended June 30, 2012 from the consumable sales of $33.2 million for the six months ended June 30, 2011. During the six months ended June 30, 2012, we had 31 bulk purchases of consumables totaling approximately $17.8 million (79% of total TSP segment consumable revenue), ranging from $0.1 million to $4.2 million, as compared with 33 bulk purchases totaling approximately $29.3 million (88% of total TSP segment consumable revenue), in the six months ended June 30, 2011. The decrease in consumable revenue was primarily attributable to volume decreases in bulk purchases from one of our partners as a result of a change in the timing of their consumable needs due to a modification to their inventory management practices. We expect these fluctuations to continue as the ordering pattern of our largest bulk purchasing partner varies due to their efforts to minimize the number of incoming qualification events, control inventory, and allow for longer development and production runs. Partners who reported royalty bearing sales accounted for $16.9 million, or 74%, of total consumable sales for the six months ended June 30, 2012.

Royalty revenue, which results when our partners sell products or services incorporating our technology, increased by 7% to $15.7 million for the six months ended June 30, 2012 compared with $14.7 million for the six months ended June 30, 2011. Our partners’ end user sales may reflect volatility from quarter to quarter and therefore, that same volatility is reflected in our reported royalty revenues on a quarterly basis. Additionally, we expect modest fluctuations in the number of commercial partners submitting royalties quarter to quarter based upon the varying contractual terms, consolidations among partners, differing reporting and payment requirements, and the addition of new partners. For the six months ended June 30, 2012, we had 44 commercial partners submitting royalties as compared to 43 for the six months ended June 30, 2011. One of our partners reported royalties totaling approximately $6.2 million, or 40% of total royalties, for the six months ended June 30, 2012, compared to $5.5 million, or 37% of total royalties for the six months ended June 30, 2011. Two other customers reported royalties totaling approximately $3.6 million, or 23% of total TSP royalty revenue (13% and 10%, respectively), for the six months ended June 30, 2012. No other customer accounted for more than 10% of total royalty revenue for the six months ended June 30, 2012. For comparative purposes, these same two customers accounted for approximately $3.3 million, or 23% (13% and 10%, respectively) of total TSP royalty revenue, for the six months ended June 30, 2011. Royalty revenues were comprised of 68% from diagnostic partners and 32% from life science research partners. Total TSP royalty bearing sales reported to us by our partners were over $196 million for the six months ended June 30, 2012, compared with over $190 million for the six months ended June 30, 2011.

Service revenue, comprised of extended warranty contracts earned ratably over the term of a contract and fees for services performed on instruments, increased by 6% to $3.6 million for the six months ended June 30, 2012 from $3.4 million for the six months ended June 30, 2011. This increase is attributable to increased penetration of the expanded installed base. At June 30, 2012 and 2011, we had 1,374 and 1,205 Luminex systems, respectively, covered under extended service agreements.

Other revenues, comprised of training revenue, shipping revenue, miscellaneous part sales, amortized license fees, reagent sales, and grant revenue, increased by 28% to $3.9 million for the six months ended June 30, 2012 from $3.0 million for the six months ended June 30, 2011. This increase is primarily the result of an increase in miscellaneous part sales, grant revenue and license fees.

Gross profit margin. The gross profit margin percentage for the TSP segment decreased to 69% for the six months ended June 30, 2012 compared to 74% for the six months ended June 30, 2011. The decrease in gross profit margins was primarily the result of the decrease in consumable sales, a higher margin item, from 49% of revenue in the first half of 2011 to 38% of revenue in the first half of 2012.

Research and development expense. Research and development expenses for the TSP segment increased to $7.3 million, or 12% of TSP segment revenue, for the six months ended June 30, 2012 compared to $6.4 million, or 9% of TSP segment revenue, for the comparable period in 2011. The increase in TSP segment research and development expense was primarily attributable to increases in materials and additional personnel costs associated with increased activity related to product development.

Selling, general and administrative expense. Selling, general and administrative expense for the TSP segment increased to $25.6 million, or 43% of TSP segment revenue, for the six months ended June 30, 2012 from $23.7 million, or 35% of TSP segment revenue, for the comparable period in 2011. The increase in the total selling, general and administrative expense dollars was primarily related to additional personnel costs associated with growth in our marketing efforts to support our global initiatives and expansion of our facilities and technology infrastructure.

Revenue. Total revenue for our ARP segment increased by 64% to $37.2 million for the six months ended June 30, 2012 from $22.8 million for the comparable period in 2011. The increase in revenue was driven primarily by the inclusion of sales of our LMA assay products. Our assay products are currently divided into two distinct categories; infectious disease testing and genetic testing, which represented 68% and 32% of total assay revenue in the first half of 2012 as compared to 47% and 53% in the first half of 2011, respectively. The top two customers, by revenue, accounted for 67% of total ARP segment revenue (49% and 18%, respectively) for the six months ended June 30, 2012 compared to 59% (31% and 28%, respectively) for the six months ended June 30, 2011. No other customer accounted for more than 10% of total ARP segment revenue during those periods. During the six months ended June 30, 2012, our ARP segment sold nine multiplexing analyzers and 31 automated punching systems compared to seven multiplexing analyzers and 78 automated punching systems during the six months ended June 30, 2011. Other revenue includes shipping revenue and training revenue.

Gross profit. The gross profit margin percentage for the ARP segment increased to 72% for the six months ended June 30, 2012 from 63% for the six months ended June 30, 2011. Gross profit for the ARP segment increased to $26.7 million for the six months ended June 30, 2012, as compared to $14.3 million for the six months ended June 30, 2011. The increase in gross profit margin percentage was primarily attributable to increased sales of high margin assays.

Research and development expense. Research and development expenses for our ARP segment were $11.8 million, or 32% of ARP segment revenue, and $9.2 million, or 40% of ARP segment revenue, for the six months ended June 30, 2012 and 2011, respectively. The increase in research and development expenses was primarily the result of increases in materials and additional personnel costs associated with the addition of employees resulting from increased activity related to product development, including clinical trials costs, together with the inclusion of $0.8 million of LMA’s research and development expenses in the six months ended June 30, 2012 results. Research and development employees and contract employees of the ARP segment increased to 115 at June 30, 2012 from 105 at June 30, 2011, primarily due to employees added by the acquisition of LMA.

Selling, general and administrative expense. Selling, general and administrative expenses, including the amortization of acquired intangibles, for the ARP segment were $11.4 million, or 31% of ARP segment revenue, for the six months ended June 30, 2012 compared to $8.3 million, or 36% of ARP segment revenue, for the six months ended June 30, 2011. The increase in selling, general, and administrative expenses is primarily due to the inclusion of LMA in the first half of 2012 results and the expansion of the life science and biodefense groups.

LIQUIDITY AND CAPITAL RESOURCES

	June 30, 2012		December 31, 2011
	(in thousands)

Cash and cash equivalents	$	75,898	$	58,282
Short-term investments		23,150		42,574
Long-term investments		5,997		6,151
	$	105,045	$	107,007

At June 30, 2012, we held cash and cash equivalents, short-term investments, and long-term investments of $105.0 million and had working capital of $140.5 million. At December 31, 2011, we held cash and cash equivalents, short-term investments, and long-term investments of $107.0 million and had working capital of $136.9 million. The decrease in cash and cash equivalents, short-term investments, and long-term investments in the six months ended June 30, 2012 is primarily attributable to stock repurchases of $9.9 million (at an average cost of $22.18 per share) and capital expenditures of $5.4 million, offset by net income of $6.5 million and proceeds from issuance of common stock of $2.4 million.

On July 11, 2012, we acquired all of the outstanding capital stock of privately-held GenturaDx, in exchange for approximately $50 million of our cash on hand. In addition, changes to the timing and frequency of the shares purchased under our share repurchase program could affect the overall timing of the outlay of cash over the remainder of the year.

We have funded our operations to date primarily through the issuance of equity securities (in conjunction with an initial public offering in 2000, subsequent option exercises, and our secondary public offering in 2008) and cash generated from operations. Our cash reserves are held directly or indirectly in a variety of short-term, interest-bearing instruments, including obligations of the United States government or agencies thereof and U.S. corporate debt securities. We do not have any investments in asset-backed commercial paper, auction rate securities, mortgage backed or sub-prime style investments.

Our future capital requirements will depend on a number of factors, including our success in developing and expanding markets for our products, payments under possible future strategic arrangements, continued progress of our research and development of potential products, the timing and outcome of regulatory approvals, the need to acquire licenses to new technology, costs associated with strategic acquisitions including integration costs and assumed liabilities, litigation expense, the status of competitive products and potential cost associated with both protecting and defending our intellectual property. Additionally, actions taken as a result of the ongoing internal evaluation of our business could result in expenditures not currently contemplated in our estimates for 2012. We believe, however, that our existing cash and cash equivalents are sufficient to fund our operating expenses, capital equipment requirements and other expected liquidity requirements for the coming twelve months. Factors that could affect our capital requirements, in addition to those listed above include: (i) continued collections of accounts receivable consistent with our historical experience; (ii) our ability to manage our inventory levels consistent with past practices; (iii) signing of partnership agreements which include significant up front license fees; and, (iv) signing of strategic investment or acquisition agreements requiring significant cash consideration. See also the "Safe Harbor Cautionary Statement" of this report and the risk factors in our 2011 10-K and our other filings with the Securities and Exchange Commission.

To the extent our capital resources are insufficient to meet future capital requirements we will have to raise additional funds to continue the development and deployment of our technologies, or to supplement our position through strategic acquisitions. There can be no assurance that debt or equity funds will be available on favorable terms, if at all, particularly given the current state of the capital markets. Any downgrade in our credit rating could adversely affect our ability to raise debt capital on favorable terms, or at all. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in dilution to our stockholders. Moreover, incurring debt financing could result in a substantial portion of our operating cash flow being dedicated to the payment of principal and interest on such indebtedness, could render us more vulnerable to competitive pressures and economic downturns and could impose restrictions on our operations. If adequate funds are not available, we may be required to curtail operations or growth strategies significantly or to obtain funds through entering into agreements on unattractive terms.

Debt

On December 12, 2003, Luminex Molecular Diagnostics (“LMD”) entered into an agreement with the Ministry of Industry of the Government of Canada under which the Government agreed to invest up to Canadian (Cdn) $7.3 million relating to the development of several genetic tests. This agreement was amended in March 2009. Funds were advanced from Technology Partnerships Canada (TPC), a special operating program. The actual payments we received were predicated on eligible expenditures made during the project period which ended July 31, 2008. LMD has received Cdn $4.9 million from TPC which is expected to be repaid along with approximately Cdn $1.6 million of imputed interest for a total of approximately Cdn $6.5 million.

LMD has agreed to repay the TPC funding through a royalty on revenues. Royalty payments commenced in 2007 at a rate of 1% of total revenue and at a rate of 2.5% for 2008 and thereafter. Aggregate royalty repayment will continue until total advances plus imputed interest has been repaid or until December 31, 2016, whichever is earlier. The repayment obligation expires on December 31, 2016 and any unpaid balance will be cancelled and forgiven on that date. Should the term of repayment be shorter than expected due to higher than expected assay revenue, the effective interest rate would increase as repayment is accelerated. Actual future sales generating a repayment obligation will vary from our projections, are subject to adjustment based upon the U.S. and Canadian exchange rate and are subject to the risks and uncertainties described elsewhere in this report and in our 2011 10-K, including under Item 1A “Risk Factors” and “Safe Harbor Cautionary Statement.”

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk. Our interest income is sensitive to changes in the general level of domestic interest rates, particularly since our investments are in short-term and long-term instruments available-for-sale. A 50 basis point fluctuation from average investment returns at June 30, 2012 would yield a less than 1% variance in overall investment return, which would not have a material adverse effect on our financial condition.

Foreign Currency Risk. Our international business is subject to risks, including, but not limited to: foreign exchange rate volatility, differing tax structures, unique economic conditions, other regulations and restrictions, and changes in political climate. Accordingly, our future results could be materially adversely impacted by changes in these and other factors.

As of June 30, 2012, as a result of our foreign operations, we have costs, assets and liabilities that are denominated in foreign currencies, primarily Canadian and Australian dollars and to a lesser extent the Euro, Renminbi, and Yen. For example, some fixed asset purchases, certain expenses, and the TPC debt of our Canadian subsidiary are denominated in Canadian dollars while sales of products are primarily denominated in U.S. dollars. All transactions in our Netherlands and Japanese subsidiaries are denominated in Euros and Yen, respectively. All transactions, with the exception of our initial capital investment, in our Chinese subsidiary are denominated in Renminbi. Sales transactions in our Australian subsidiary are primarily denominated in Australian or U.S. dollars while fixed asset purchases and expenses are primarily denominated in Australian dollars. As a consequence, movements in exchange rates could cause our foreign currency denominated expenses to fluctuate as a percentage of net revenue, affecting our profitability and cash flows. A significant majority of our revenues are denominated in U.S. dollars. The impact of foreign exchange on foreign denominated balances will vary in relation to changes between the U.S. dollar, Canadian dollar, Australian dollar, Euro, Yen, and Renminbi exchange rates. A 10% change in these exchange rates in relation to the U.S. dollar would result in an income statement impact of approximately $758,000 on foreign currency denominated asset and liability balances as of June 30, 2012. As a result of our efforts to expand globally, in the future we will be exposed to additional foreign currency risk in multiple currencies; however, at this time, our exposure to foreign currency fluctuations is not material.

In addition, the indirect effect of fluctuations in interest rates and foreign currency exchange rates could have a material adverse effect on our business financial condition and results of operations. For example, currency exchange rate fluctuations could affect international demand for our products. In addition, interest rate fluctuations could affect our customers’ buying patterns. Furthermore, interest rate and currency exchange rate fluctuations may broadly influence the United States and foreign economies resulting in a material adverse effect on our business, financial condition and results of operations. As a result, we cannot give any assurance as to the effect that future changes in foreign currency rates will have on our consolidated financial position, results of operations or cash flows. Our aggregate foreign currency transaction gain of $42,000 was included in determining our consolidated results for the quarter ended June 30, 2012.
