NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 ("U.S. GAAP") for interim financial information and the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP 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 months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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, 2014 (the "2014 10-K").

NOTE 2 — RESTRUCTURING

In August 2013, the Company announced a restructuring plan focused on its Newborn Screening Group and its Brisbane, Australia office where automated punching systems were designed and manufactured. The Company halted development of the newborn screening assay in 2013 and the manufacturing facility in Brisbane, Australia was closed in the third quarter of 2014. The Company reviewed the requirements for held-for-sale and discontinued operations presentation and determined the manufacturing facility in Brisbane, Australia did not meet the altered definition of a discontinued operation under the recent amended accounting guidance as it was not a strategic shift with a major effect on the Company's operations and finances. Management applied this new guidance for the facility in Brisbane, Australia.

The Company recorded pre-tax restructuring charges primarily consisting of the non-cash impairment of inventory, intangible assets and property and equipment, together with employee separation costs, which primarily included severance pay and other separation costs such as outplacement services and benefits. The Company recorded non-cash impairment charges of $2.8 million in 2014, including a write-down of goodwill of $1.2 million resulting from the disposal of the manufacturing facility in Brisbane, Australia. See Note 6 — Goodwill and Other Intangible Assets. In addition, the Company measured and accrued the facilities exit costs, primarily consisting of cease-use losses recorded upon vacating the facilities, at fair value upon the Company's exit in the third quarter of 2014. As the final restructuring costs were paid in the fourth quarter of 2014, there is no remaining balance of accrued restructuring costs as of March 31, 2015 or December 31, 2014.

Non-cash impairment charges:
Inventory	$	1,183

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 March 31, 2015 and December 31, 2014, all of the Company’s marketable securities were classified as available for sale. Marketable securities are recorded as either short-term or long-term on the balance sheet based on the 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.

Available-for-sale securities consisted of the following as of March 31, 2015 (in thousands):



	Amortized Cost		Gains in Accumulated Other Comprehensive Income		Losses in Accumulated Other Comprehensive Income		Estimated Fair Value
Current:
Cash equivalents	$	3,574	$	—	$	—	$	3,574
Total current securities	3,574		—		—		3,574

Cash equivalents	$	3,569	$	—	$	—		$	3,569
Total current securities	3,569		—		—			3,569

Non-government sponsored debt securities	6,002		—		(16		)	5,986
Total noncurrent securities	16,002		—		(27		)	15,975

Total available-for-sale securities	$	19,571	$	—	$	(27	)	$	19,544

Table of Contents

There were no proceeds from the sales of available-for-sale securities during the three months ended March 31, 2015 or 2014. Realized gains and losses on sales of investments are determined using the specific identification method. Realized gains and losses are included in other income, net in the Consolidated Statements of Comprehensive Income. All of the Company's available-for-sale securities with gross unrealized holding losses as of March 31, 2015 and December 31, 2014 had been in a loss position for less than 12 months.

The estimated fair value of available-for-sale debt securities at March 31, 2015 and December 31, 2014, by contractual maturity, was as follows (in thousands):



	Estimated Fair Value
	March 31, 2015		December 31, 2014
Due in one year or less	$	—	$	—
Due after one year through two years	16,008		15,975
	$	16,008	$	15,975

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

The Company owns a minority interest in a private company based in the U.S. through its investment of $1.0 million in the third quarter of 2012. This minority interest is included at cost in other long-term assets on the Company’s Consolidated Balance Sheets as the Company does not have significant influence over the investee since the Company owns less than 20% of the voting equity in the investee and the investee is not publicly traded.

The Company's other minority interest in a private company was acquired by a third party in July 2013. The Company realized a gain of $5.4 million on this minority interest investment in the third quarter of 2013 and an additional gain of $0.9 million in the first quarter of 2015 related to the settlement of escrowed funds.

The Company regularly evaluates the carrying value of its 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 (Loss). As the inputs utilized for the Company's periodic impairment assessment are not based on observable market data, this cost-method investment is classified within Level 3 of the fair value hierarchy. To determine the fair value of this investment, the Company uses all available financial information related to the entities, including information based on recent or pending third-party equity investments in these entities. In certain instances, a cost-method investment's fair value is not estimated as there are no identified events or changes in the circumstances that may have a significant adverse effect on the fair value of the investment and to do so would be impractical.

NOTE 4 — INVENTORIES, NET

Inventories are stated at the lower of cost or market, with cost determined according to the standard cost method, which approximates the first-in, first-out method. The Company routinely assesses its on-hand inventory for timely identification and measurement of obsolete, slow-moving or otherwise impaired inventory. Inventories consisted of the following (in thousands):



	March 31, 2015		December 31, 2014
Parts and supplies	$	19,339	$	19,354
Work-in-progress	5,364		8,687
Finished goods	9,020		8,575
	$	33,723	$	36,616

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 U.S. GAAP 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. There were no transfers between Level 1, Level 2, or Level 3 measurements for the three month period ended March 31, 2015.

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 March 31, 2015 and December 31, 2014 (in thousands):

NOTE 6 — GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is reviewed for impairment at least annually at the beginning of the fourth quarter, or more frequently if impairment indicators arise. This goodwill is not expected to be deductible for tax purposes.

In connection with the closure of the manufacturing facility in Brisbane, Australia in the third quarter of 2014, the Company recorded a write-down of goodwill of $1.2 million. The amount of goodwill the Company included in the carrying amount of the disposed manufacturing business in Brisbane, Australia was based upon the relative fair value of that facility compared to the portion of the reporting unit that was retained.

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



	March 31, 2015		December 31, 2014

NOTE 8 — 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 March 31,
	2015		2014
Numerator:
Net income	$	7,453	$	5,966
Denominator:
Denominator for basic net income per share - weighted average common stock outstanding	41,873		41,209
Effect of dilutive securities: stock options and awards	321		616
Denominator for diluted net income per share - weighted average shares outstanding - diluted	42,194		41,825
Basic net income per share	$	0.18	$	0.14
Diluted net income per share	$	0.18	$	0.14

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. Stock options to acquire approximately 0.7 million and 0.3 million shares for the three months ended March 31, 2015 and 2014, respectively were excluded from the computations of diluted EPS because the effect of including those stock options would have been anti-dilutive.

NOTE 9 — STOCK-BASED COMPENSATION

The Company’s stock option activity for the three months ended March 31, 2015 was as follows:

As of March 31, 2015, there was $21.2 million and $4.3 million of unrecognized compensation costs related to RSAs and RSUs, respectively. That cost is expected to be recognized over a weighted average period of 3.06 years for the RSAs and 2.45 years for the RSUs. The Company issues a small number of cash settled restricted stock units pursuant to the Company's equity incentive plan in certain foreign countries. These grants do not result in the issuance of common stock and are considered immaterial by the Company.

The following are the stock-based compensation costs recognized in the Company’s condensed consolidated statements of comprehensive income (in thousands):



	Three Months Ended March 31,
	2015		2014
Cost of revenue	$	234	$	207

NOTE 10 — ACCRUED LIABILITIES

Accrued Liabilities consisted of the following (in thousands):



	March 31, 2015		December 31, 2014
Compensation and employee benefits	$	4,289	$	9,960
Income and other taxes	1,437		870
Warranty costs	406		488
Other	2,271		2,800
	$	8,403	$	14,118

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.

Accrual for warranty costs	102
Accrued warranty costs at March 31, 2015	$	406

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 three months ended March 31, 2015 was 28.25%, including amounts recorded for discrete events. This differs from the statutory rate of 35% primarily because of the worldwide mix of consolidated earnings and losses 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., Canada, and the Netherlands; currently expects a full year effective tax rate of less than 30%, and therefore cash taxes to be paid are expected to continue to be less than 10% of book tax expense.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, Australia, Canada, China, Hong Kong, Japan, the Netherlands, and various states. Due to net operating losses, the U.S., Canadian and Australian tax returns dating back to 2010 can still be reviewed by the taxing authorities. The Company recorded liabilities of $9,200 associated with its uncertain tax positions in the first quarter of 2015. No other material changes to this liability are expected within the next 12 months. For the three months ended March 31, 2015, 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.

Table of Contents

When and if it appears probable in management's judgment, and based upon consultation with outside counsel, that we will incur monetary damages or other costs in connection with any claims or proceedings, and such costs can be reasonably estimated, we record the estimated liability in the financial statements. If only a range of estimated losses can be estimated, we record an amount within the range that, in management's judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we record the liability at the low end of the range of estimates. Any such accrual would be charged to expense in the appropriate period. We disclose significant contingencies when the loss is not probable and/or the amount of the loss is not estimable, when we believe there is at least a reasonable possibility that a loss has been incurred. We recognize costs associated with legal proceedings in the period in which the services were provided. There can be no assurance that we will successfully defend these suits or that a judgment against us would not materially adversely affect our operating results.

NOTE 13 — RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued a new standard on revenue recognition which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.

OVERVIEW

We develop, manufacture and sell proprietary biological testing technologies and products with applications throughout the diagnostics and life sciences 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, digital signal processors 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 PCR (Polymerase Chain Reaction) and multiplexed PCR assays. Our MultiCode assay chemistry is a flexible platform for both real-time PCR and multiplex PCR-based applications. Our MultiCode technology is powered by a base pair (man-made nucleotide pair isoC:isoG in addition to the A:T and G:C nucleotide pairs found in nature) that does not exist in nature, but can be combined with natural base pairs, and incorporated into a wide range of molecular diagnostic applications. The MultiCode base pair is recognized by naturally occurring enzymes and can be used for the specific placement of reporter molecules and to increase the molecular recognition capabilities of hybridization-based assays. The MultiCode base pair enables solutions to complex molecular challenges that were previously not possible with natural nucleic acid alone.

Table of Contents

Our end user customers and partners, which include laboratory professionals performing research, clinical laboratories performing tests on patients as ordered by physicians and other laboratories, have a fundamental need to perform high quality testing as efficiently as possible. Luminex employs a two-pronged business model. We have licensed our xMAP technology to partner companies, which in turn then develop products that incorporate the xMAP technology 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 March 31, 2015, Luminex had 70 strategic partners, of which 48 have released commercialized reagent-based products utilizing our technology. Additionally, we market and sell our proprietary assay products and instrumentation directly to the end user through our direct sales force.

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


•	Assay revenue is generated from the sale of our kits which are a combination of chemical and biological reagents and our proprietary xMAP bead technology used to perform diagnostic and research assays on samples as well as real-time PCR and multiplexed PCR assays using our proprietary MultiCode technology.


•	System revenue is generated from the sale of our xMAP multiplexing analyzers and peripherals.


•	Consumable revenue is generated from the sale of our dyed polystyrene microspheres, along with sheath and drive 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 microspheres to an end user or when a partner utilizes a kit 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.


•	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.

First Quarter 2015 Highlights


•	Consolidated revenue was $57.7 million for the quarter ended March 31, 2015, representing a 2% increase over revenue for the first quarter of 2014.


•	Assay revenue of $25.4 million for the quarter ended March 31, 2015, representing a 17% increase over assay revenue for the first quarter of 2014. Infectious disease sales comprised approximately 64% of total assay sales, with genetic testing sales representing 36% of total assay sales.


•	Partners reported $126.0 million of royalty bearing end user sales on xMAP technology for the quarter, a 14% increase over the first quarter of 2014, contributing to the 6% increase in royalty revenue from the first quarter of 2014.


•	80% of consolidated revenue was attributable to our recurring revenue streams (consumable sales, royalty revenue and assay sales).


•	Began clinical trials for ARIES System and ARIES HSV 1&2 Assay.


•	Shipments of 193 multiplexing analyzers, which included 91 Luminex® 100/200^TM systems, 86 MAGPIX® systems and 16 FLEXMAP 3D® systems.


•	Received Health Canada approval for xTAG CYP2D6 Kit v3.

Consumables Sales and Royalty Revenue Trends

We have experienced significant fluctuations in consumable revenue over the past three years. Overall, the fluctuations manifested themselves through periodic changes in volume from our largest purchasing customers. On a quarterly basis, these customers account for more than 70% of our total consumable sales volume. We expect these fluctuations to continue as the ordering patterns and inventory levels of our largest bulk purchasing partners remain variable. Additionally, even though we experience variability in consumable revenue, the key indicator of the success of our partners’ commercialization efforts is the rising level of royalties and reported royalty bearing sales.

Reimbursement Landscape

We may be impacted by future changes to the reimbursement landscape. Commercial payors may adopt coding and bundling requirements that are similar to those made by Medicare. Further, in April 2014, the Protecting Access to Medicare Act (PAMA) was enacted. Beginning in 2016, PAMA requires clinical laboratories to report to CMS the volume of each laboratory test and the price paid by private payors. CMS must set future Medicare fee schedules using weighted medians from these datasets. This requirement could exert downward pressure on Medicare reimbursement, because reimbursement rates for clinical laboratory services of commercial payors are often lower than rates paid by Medicare. We will continue to monitor the reimbursement landscape closely.

Future Operations

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


•	clinical validation and preparation for commercial launch of our ARIES system, the next generation sample-to-answer platform for our MultiCode-RTx technology, including in vitro diagnostic (IVD) assays;


•	development of a pipeline of assays for the ARIES system menu;


•	development of the next generation multiplex chemistry, including the next generation of our Respiratory Viral Panel line of IVD assays;


•	continued execution of our pharmacogenetic (PGx) strategy;


•	continued execution of our direct sales strategy, including developing the infrastructure necessary to support our sales force and decreasing reliance on our distributors;

Table of Contents


•	commercialization, regulatory clearance and market adoption of products, including commercialization of MultiCode analyte specific reagents outside of the United States;


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


•	adoption and use of our platforms and consumables by our customers for testing services;


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


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


•	continued adoption and development of partner products incorporating Luminex technology through effective partner management.

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 as a result of the timing of development expenses, clinical validation and clinical trials in advance of the commercial launch of our new products.

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 U.S. GAAP 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 March 31, 2015 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 2014 10-K.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2015 COMPARED TO THREE MONTHS ENDED MARCH 31, 2014

Selected consolidated financial data for the three months ended March 31, 2015 and 2014 is as follows (dollars in thousands):



	Three Months Ended March 31,
	2015			2014			Variance			Variance (%)
Revenue	$	57,741		$	56,561		$	1,180		2	%
Gross profit	$	40,219		$	39,954		265			1	%
Gross margin percentage	70		%	71		%	(1		)%	N/A

Income from operations	$	9,693		$	8,185		1,508			18	%

Total revenue increased by 2% to $57.7 million for the three months ended March 31, 2015 from $56.6 million for the comparable period in 2014. The increase was primarily attributable to an increase in royalty revenue and assay sales, partially offset by decreased consumable sales.

Table of Contents

A breakdown of revenue for the three months ended March 31, 2015 and 2014 is as follows (dollars in thousands):



	Three Months Ended March 31,
	2015		2014		Variance			Variance (%)
System sales	$	5,964	$	6,400	$	(436	)	(7	)%
Consumable sales	9,896		12,768		(2,872		)	(22	)%

Other revenue	3,392		3,340		52			2	%
	$	57,741	$	56,561	$	1,180		2	%

We continue to experience revenue concentration in a limited number of strategic partners. Four customers accounted for 47% (22%, 10%, 9% and 6%, respectively) of consolidated total revenue in the first quarter of 2015. For comparative purposes, these top four customers accounted for 50% (20%, 17%, 7% and 6%, respectively) of total revenue in the first quarter of 2014. No other customer accounted for more than 10% of consolidated total revenue during those periods.

Revenue from the sale of systems and peripheral components decreased 7% to $6.0 million for the three months ended March 31, 2015 from $6.4 million for the three months ended March 31, 2014, due to the decrease in the total multiplexing analyzer placements. We sold 193 multiplexing analyzers in the first quarter of 2015, which included 86 of our MAGPIX systems, as compared to 208 multiplexing analyzers sold for the corresponding prior year period, which included 78 MAGPIX systems, bringing total multiplexing analyzer sales since inception to 11,880 as of March 31, 2015. We anticipate that our increased focus on direct sales will drive the placement of reagent rental multiplexing analyzer systems in lieu of multiplexing analyzer system sales to distributors. For the three months ended March 31, 2015, five of our partners accounted for 157, or 81%, of total multiplexing analyzers sold. Five of our partners accounted for 157, or 75%, of total multiplexing analyzers sold for the three months ended March 31, 2014.

Consumable sales, comprised of microspheres and sheath fluid, decreased to $9.9 million for the three months ended March 31, 2015 from $12.8 million for the three months ended March 31, 2014. During the three months ended March 31, 2015, we had 16 bulk purchases of consumables totaling approximately $7.2 million (73% of total consumable revenue), ranging from $0.1 million to $2.0 million, as compared with 15 bulk purchases totaling approximately $10.3 million (81% of total consumable revenue), for the three months ended March 31, 2014. The decrease in bulk purchases in first quarter of 2015 is the primary driver to the decrease in consumable revenue from the prior year quarter and is primarily the result of inventory challenges experienced by our largest partner, which is expected to affect consumable sales over the next several years. However, excluding consumables from our largest partner for the three months ended March 31, 2015 and 2014, consumables from our remaining partners grew by 14%. We expect fluctuations in consumable sales on an ongoing basis. Partners who reported royalty bearing sales accounted for $5.3 million, or 53%, of consumable sales for the three months ended March 31, 2015 compared to $10.4 million, or 81%, of the total consumable sales for the three months ended March 31, 2014.

Royalty revenue, which results when our partners sell products or services incorporating our technology, increased 6% to $10.7 million for the three months ended March 31, 2015 from $10.0 million for the three months ended March 31, 2014. We believe this is primarily the result of menu expansion and increased utilization of our partners’ assays on our technology. We expect modest fluctuations in the royalties submitted quarter to quarter based upon the varying contractual terms, differing reporting and payment requirements, and the addition of new partners. 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. Total royalty bearing sales on xMAP and MultiCode technology reported to us were $126.0 million and $1.0 million, respectively, for the three months ended March 31, 2015 as compared to $110.6 million and $0.8 million, respectively, for the three months ended March 31, 2014.

Assay revenue increased 17% to $25.4 million for the three months ended March 31, 2015 from $21.7 million for the three months ended March 31, 2014. The increase in assay revenue is driven primarily by an increase in both of our primary assay portfolios: infectious disease testing and genetic testing assay products which increased 15% and 22% from the first quarter of 2014, respectively. Additionally, infectious disease testing and genetic testing assay products represented 64% and 36%, respectively, of total assay revenue in the first quarter of 2015, compared to 65% and 35%, respectively, in the first quarter of 2014. Our largest customer, by revenue, accounted for 47% of total assay revenue for the three months ended March 31, 2015 compared to 49% for the three months ended March 31, 2014. No other customer accounted for more than 10% of total assay revenue during those periods. Certain genetic testing assay products revenue from our largest customer is under significant pressure from competing technologies and, although timing is uncertain, the loss of that revenue, if it materializes, could have an impact in excess of $1 million per month on our assay revenue.

Service revenue, comprised of extended warranty contracts earned ratably over the term of a contract and time and materials for billable service work not under an extended warranty contract, remained flat at $2.3 million for the first quarter of 2015 compared to the first quarter of 2014. At March 31, 2015, we had 1,619 Luminex systems covered under extended service agreements and $4.4 million in deferred revenue related to those contracts. At March 31, 2014, we had 1,578 Luminex systems covered under extended service agreements and $4.0 million in deferred revenue related to those contracts.

Other revenue, which includes training revenue, shipping revenue, miscellaneous part sales, amortized license fees, milestone payments from our development agreement with Merck and revenue from agreements with U.S. government agencies, remained flat at $3.4 million for the three months ended March 31, 2015 compared to $3.3 million for the three months ended March 31, 2014.

Gross Profit. Gross profit increased to $40.2 million for the three months ended March 31, 2015, as compared to $40.0 million for the three months ended March 31, 2014. Gross margin (gross profit as a percentage of total revenue) was 70% for the three months ended March 31, 2015, a slight decrease from 71% for the three months ended March 31, 2014. Although the concentration of sales in our higher margin items (assays, consumables and royalties) was higher than in the prior year quarter, representing 80% of revenue for the three months ended March 31, 2015 compared to 79% for the three months ended March 31, 2014, the change in mix resulting from a decreased concentration of consumables and an increased concentration of assays drove the slight decrease in gross margin. We anticipate continued fluctuation in gross margin and related gross profit primarily as a result of variability in consumable and system purchases and seasonality effects inherent in our assay revenue.

Research and Development Expense. Research and development expense decreased to $10.1 million, or 18% of total revenue, for the three months ended March 31, 2015 from $11.1 million, or 20% of total revenue, for the three months ended March 31, 2014. The decrease in research and development expense was primarily the result of the savings in materials spending associated with advancement in the ARIES development phases, including transitioning from development work in the prior year to beginning clinical trials in the current year, and decreased personnel and stock compensation costs. Research and development headcount at March 31, 2015 was 202 as compared to 203 at March 31, 2014. The focus of our research and development activities has been the development and clinical validation of our next generation sample-to-answer platform for our ARIES system.

Selling, General and Administrative Expense. Selling, general and administrative expenses, excluding the amortization of acquired intangible assets, increased modestly to $19.5 million for the three months ended March 31, 2015 from $19.4 million for the three months ended March 31, 2014. Selling, general and administrative headcount at March 31, 2015 was 297 as compared to 288 at March 31, 2014. As a percentage of revenue, selling, general and administrative expense, excluding the amortization of acquired intangible assets, was 34% in the first quarter of 2015, consistent with the first quarter of 2014.

Restructuring costs. We recorded total pre-tax restructuring charges of $0.8 million in the first quarter of 2014. No restructuring charges were recorded in the first quarter of 2015. The portion of these charges that pertained to the non-cash impairment of inventory and certain employee separation costs, $0.6 million, was recorded to cost of revenue. The portion of these charges that pertained to the non-cash impairment of property and equipment together with certain employee separation costs, $0.2 million, was recorded to restructuring costs within our operating expenses.

Other Income, net. Other income, net increased to $0.7 million for the three months ended March 31, 2015 from a loss of $19,000 for the three months ended March 31, 2014. The increase was due to the receipt of additional escrowed funds from the liquidation of our minority interest in a private company in 2013, which resulted in an additional gain of $0.9 million in the current quarter. This gain was partially offset by a litigation settlement.

Income taxes. Our effective tax rate for the three months ended March 31, 2015 was an expense of 28%, or $2.9 million, as compared to an expense of 27%, or $2.2 million, for the three months ended March 31, 2014. As a result of the partial release of Canadian deferred tax assets valuation allowance in the fourth quarter of 2014, we are recording income tax expense on profits generated in our Canadian subsidiary and as a result expect our consolidated effective tax rate to be in the 25% to 35% range over the next several years, absent any other significant discrete items. We continue to assess our business model and its impact in various tax jurisdictions.

LIQUIDITY AND CAPITAL RESOURCES



	March 31, 2015		December 31, 2014
	(in thousands)
Cash and cash equivalents	$	94,907	$	91,694
Long-term investments	$	16,008	$	15,975
	$	110,915	$	107,669

At March 31, 2015, we held cash and cash equivalents and long-term investments of $110.9 million and had working capital of $148.2 million. At December 31, 2014, we held cash and cash equivalents and long-term investments of $107.7 million and had working capital of $146.7 million. The $3.2 million increase in cash, cash equivalents and investments is primarily attributable to strong operating cash flows of $10.9 million, coupled with $0.9 million in proceeds from our employee stock purchase plan (ESPP) and stock option exercises, which funded our capital expenditures of $8.9 million, which was primarily related to expenditures for ARIES cassette automation. Based on our belief that our current general and administrative cost structure could support significant growth without significant addition, we expect to generate incremental cash and investments on a quarterly basis absent any significant strategic investments or operational initiatives. We expect to generate incremental cash and investments on a quarterly basis absent any significant strategic investments or operational initiatives.

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 non-government sponsored debt securities. We do not have any investments in asset-backed commercial paper, auction rate securities, or 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 and 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 2015. One of our short term capital requirements is the completion of our current in-process research and development project related to our acquisition of GenturaDx, the foundation of our ARIES System, which is scheduled to be completed and commercialized in 2015. The estimated aggregate cost to complete this project is between $1.0 million and $3.0 million. We believe 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) volatility in our key partners' consumable purchasing patterns; (iv) signing of partnership agreements which include significant up front license fees; (v) our stock repurchase programs from time to time and (vi) entering into strategic investment or acquisition agreements requiring significant cash consideration. See also the "Safe Harbor Cautionary Statement" of this report and the risk factors in the 2014 10-K and our other filings with the SEC.

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. Any decline in our credit worthiness 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 significantly or to obtain funds through entering into agreements on unattractive terms.

Debt

In May 2014, the Company repaid all of its outstanding debt.

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 instruments available-for-sale. A 50 basis point fluctuation from average investment returns at March 31, 2015 would yield a less than 0.5% variance in overall investment return, which would not have a material 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 March 31, 2015, as a result of our foreign operations, we have costs, assets and liabilities that are denominated in foreign currencies, primarily Canadian dollars and to a lesser extent the Euro, Renminbi, Hong Kong dollar and Yen. For example, some fixed asset purchases and certain expenses in our Canadian subsidiary are denominated in Canadian dollars while sales of products are primarily denominated in U.S. dollars. Transactions in our Netherlands, Japanese and Hong Kong subsidiaries are primarily denominated in Euros, Yen and Hong Kong dollars, respectively. The majority of transactions, with the exception of our initial capital investment, in our Chinese subsidiary are denominated in Renminbi. 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, Euro, Yen, Renminbi and Hong Kong dollar 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 $769,000 on foreign currency denominated asset and liability balances as of March 31, 2015. 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. We regularly assess the market to determine if additional strategies are appropriate to mitigate future risks.

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 loss of $501,000 was included in determining our consolidated results for the quarter ended March 31, 2015.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (“Exchange Act”), which are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as of the end of the period covered by this quarterly report. Based on the evaluation and criteria of these disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Exchange Act Rule 13a-15(d) during the quarter ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
