LETTER TO STOCKHOLDERS

NACHUM “HOMI” SHAMIR

PRESIDENT AND CHIEF EXECUTIVE OFFICER

Dear Stockholders,

2015 was a year of significant achievement for Luminex  

in terms of realigning our focus, sharpening our commitment to 
flawless execution, and driving stockholder value. Importantly, 
we have strengthened our balanced, diversified, and profitable 
business model that positions us as a market leader in the 
diagnostic landscape, and allows us to grow stockholder  
value in even the most tumultuous of market conditions. 

2015 FINANCIAL RESULTS
  We generated strong financial results in 2015, achieving 
record revenue of $238 million. Thanks to favorable product mix 
and improving manufacturing yields, we achieved  solid corporate 
gross margins of 71%. With an eye on efficient resource allocation 
and investment, Luminex generated approximately $55 million in 
operating cash flow and ended the year with $148 million in cash 
and investments.    

FOUR PILLARS OF GROWTH

Since our founding, Luminex has developed into a premier 
solutions provider to laboratories in the life science and diagnostics 
market worldwide. Our recent success can be attributable to our 
balanced and diversified business model, which we refer to as the 
Four Pillars of Growth. We believe this model will enable us to 
accelerate future revenue and earnings growth.

The first pillar, our Partner business, accounts for more than 

50% of our revenue and consists primarily of our high margin 
consumables and royalties, as well as our multiplexing systems. 
Thanks to the long-term commitment and investment by these 
strategic partners, many of whom are leaders in their respective 
markets, we have established a sizable footprint with over 12,500 
multiplexing analyzers sold to date. As Luminex continues to 
invest in core technologies, so too do our strategic partners.  
This partnership synergy enhances the value of our proprietary 
technology to the end-customer, and positions Luminex well to 
serve our target life science and diagnostic markets in the future. 
Our second pillar is the core molecular diagnostics business, 

which is the fastest growing part of Luminex. We continue to 
prove our innovative edge in multiplex molecular testing and  
focus on two key specialties – infectious diseases and genetics.  
We have enjoyed strong double digit growth in both specialties 
given the advantages of multiplex technology and the broad and 

growing test menu. And with the expansion of our direct sales 
force, the FDA clearance of our NxTAG® Respiratory Pathogen 
Panel, and the launch of the new ARIES® System in 2015,  
we expect our molecular diagnostic business will lead our  
future growth. 

Our third pillar is the ARIES® System. Designed with 
significant customer collaboration, the ARIES® molecular 
diagnostic platform increases laboratory efficiency, ensures 
result accuracy, and fits seamlessly into today’s lean laboratory 
environment. We believe ARIES® can increase our potential market 
to cover up to 6,500 hospital labs; a 13 fold increase over our 
current available customer base in the U.S. In October, we received 
FDA clearance for the ARIES® System and the ARIES® HSV 1&2 
Assay, a key milestone for the company. Over the coming years, 
our ARIES® development activities will focus on expanding assay 
content, which includes both IVD assays and a portfolio of 
research use only and analyte specific reagents. Looking forward, 
we are also accelerating development of a new proprietary 
chemistry which will expand ARIES® multiplex capabilities without 
a change in hardware or cassette design, offering our customers  
an unrivalled breadth of plex testing capabilities. 

Our fourth pillar, is our strong financial position. We are 
profitable, have a healthy balance sheet with approximately  
$148 million in cash and investments and no debt. This positions 
us well against our competition to take advantage of opportunities 
when they arise.    

LOOKING FORWARD
  With our Four Pillars of Growth strategy and the exciting new 
products we have on the market, our future is very bright. I would 
like to thank our stockholders for their continued support and 
confidence, and thank our more than 800 employees worldwide 
for their outstanding efforts in getting us to where we are, and  
for their continued dedication to taking us even farther.

Sincerely,

Homi Shamir
President and Chief Executive Officer

Overview

PART I

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

We have established a position in several segments of the life sciences industry by developing and delivering products that 
meet a variety of customer needs in specific market segments, including multiplexing, accuracy, precision, sensitivity, specificity, 
reduction of labor and ability to test for proteins and nucleic acids. These needs are addressed by our proprietary technology, which 
allows the end user in a laboratory to perform biological testing in a multiplexed format. Multiplexing allows for many different 
laboratory results to be generated from one sample with a single assay. This is important because our end user customers, which 
include laboratory professionals performing research and 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. Until the availability of 
multiplexing technology such as our xMAP® (Multi-Analyte-Profiling) technology, the laboratory professional had to perform 
one assay at a time in a sequential manner, and if additional testing was required on a sample, a second assay would be performed 
to generate the second result, and so on until all the necessary tests were performed.  

We have a full range of instruments using our xMAP technology:  our LUMINEX 100/200™ systems offer 100-plex testing;  
our FLEXMAP 3D® system is our high-throughput, 500-plex testing system; and our MAGPIX® system provides 50-plex testing 
at a lower cost using imaging rather than flow cytometry.  By using our xMAP technology, the end users are able to be more 
efficient by generating multiple simultaneous results per sample. We believe that this technology may also offer advantages in 
other industries, such as in food safety/animal health and bio-defense/bio-threat markets. Using the products Luminex has available 
today, up to 500 simultaneous analyte results can be determined from a single sample.

We primarily serve the diagnostics, pharmaceutical and life sciences industries by marketing products, including our testing 
equipment and assays, to various types of testing laboratories. We have a large installed base of systems that has grown primarily 
from the following:

• 

placements made by partners who either:

• 

• 

license our xMAP technology and develop products that incorporate our xMAP technology into products that 
they then sell to end users, or 
purchase our proprietary xMAP laboratory instrumentation and our proprietary xMAP microspheres and sell 
xMAP-based assay products and/or xMAP-based testing services, which run on the xMAP instrumentation, and 
pay a royalty to us; and

• 

our direct sales force that focuses on the sale of molecular diagnostic assays that run on our systems.  

As of December 31, 2015, we had 73 strategic partners, 48 of which have developed reagent-based products utilizing our 
technology. Luminex and these partners have sold approximately 12,684 xMAP-based instruments in laboratories worldwide as 
of  December 31,  2015.  Our  remaining  partners  are  in  various  stages  of  development  and  commercialization  of  products 
incorporating our technology.

A primary focus for our growth is the development and sale of molecular diagnostic assays utilizing our proprietary xMAP, 
xTAG® and NxTAG® technologies on our installed base of systems.  We utilize a direct sales model for sales of these products, 
which is intended to take advantage of our increasing installed base of xMAP-based instrumentation.  Our assays are primarily 
focused on multiplexed applications for the human molecular clinical diagnostics market. Our assay products are currently focused 
on three segments of the molecular diagnostic testing market: human genetics, personalized medicine and infectious disease. 

1

In addition to the sales to this installed based, we have recently received U.S. Food and Drug Administration (FDA) clearance 
for our ARIES® system.  The ARIES® system is a sample to answer clinical test system that automates and integrates extraction 
of nucleic acid from a clinical sample, performs real-time polymerase chain reaction (PCR), and detects multiple signals generated 
by target specific probes. The ARIES® system is used with specific assays to measure multiple analytes indicative of infectious 
disease.    The ARIES®  system  uses  internal  barcode  scanning  and  other  advanced  features  to  minimize  operator  errors.  Two 
independent modules each support from one to six cassettes, allowing both STAT and Batch testing.  The ARIES® system can run 
both In Vitro Diagnostics (IVD) and MultiCode® Analyte Specific Reagents (ASRs) simultaneously with a common Universal 
Assay Protocol. An integrated touchscreen computer eliminates the need for a separate computer, stand-alone keyboard and mouse; 
thus maximizing valuable bench space.   The ARIES® system was commercially launched in the fourth quarter of 2015.  We also 
received FDA clearance for the ARIES® HSV (herpes simplex virus) 1&2 Assay in the fourth quarter of 2015.

Luminex was incorporated under the laws of the State of Texas in May 1995 and reincorporated in the State of Delaware in 

February 2000.

Industry Background

The life sciences industry uses assays to detect the presence and characteristics of certain biochemicals, proteins or nucleic 
acids in a sample. Drug discovery, genetic analysis, pharmacogenomics, clinical diagnostics and general biomedical research all 
use assays. For example, assays can be used to:

•  measure the presence and quantity of substances such as infectious agents, antigens for histocompatibility, hormones, 
cancer markers and other proteins in a patient’s blood, other body fluid or tissue to assist physicians in diagnosing, treating 
or monitoring disease conditions;

• 

detect genetic variations, such as single nucleotide polymorphisms or genetic mutations present in inherited diseases;

•  measure the response to a compound or dosage by measuring cellular activity for drug discovery and development; and

• 

assist physicians in prescribing or dosing the appropriate drug therapy based on the patient’s genetic makeup, a field 
known as pharmacogenetics.

The life sciences customer can purchase assays in the form of complete off-the-shelf kits, develop them from scratch or utilize 

a customized service to meet the customer's specific needs.

Our xMAP technology is an open architecture, multiplexing technology that combines existing biological testing techniques 
with illumination, advanced digital signal processing, detection and proprietary software. With our technology, discrete assays are 
performed on the surface of color-coded microspheres. These microspheres are read in a compact analyzer that utilizes lasers or 
light emitting diodes (LEDs), detectors, charge-coupled device imaging and high-speed digital signal processing to simultaneously 
identify the assay and measure the individual assay results. The key features of xMAP technology include the following:

•  Multi-analyte/multi-format

xMAP technology has been designed to simultaneously perform up to 500 distinct assays in a single tube or well of a microtiter 
plate using only a small amount of sample. Moreover, unlike most existing technologies that are dedicated to only one type 
of  assay,  xMAP  can  perform  multiple  types  of  assays  including  enzymatic,  genetic  and  immunologic  tests  on  the  same 
instrumentation platform.

• 

Flexibility/scalability

xMAP technology allows flexibility in customizing test panels. Panels can be modified to include new assays in the same tube 
by adding additional microsphere sets. It is also scalable, meaning that there is no change in the manufacturing process and 
only minimal changes to the required labor to produce a small or large number of microsphere-based tests.

3

 
•  Both protein and nucleic acid applications on a single platform

xMAP technology has an advantage due to its ability to analyze both proteins and nucleic acids.  This allows customers to 
utilize a single platform to evaluate samples across more biological parameters and generate a more complete assessment of 
these samples.  Alternative technologies are typically restricted to either proteins or nucleic acid, requiring customers to use 
two or more technologies from other vendors to get the same information.

•  High throughput

Our technology can perform up to 500 tests in a single well permitting up to 96,000 tests to be detected in approximately one 
hour with only a small amount of sample.  Rapid sample analysis permits efficient use for high-throughput applications.  

•  Ease of use

Most xMAP-based assays are simple to perform. A test sample is added to a solution containing microspheres that have been 
coated with reagents. The solution is then processed through one of our xMAP systems which incorporates proprietary software 
to automate data acquisition and analysis in real-time.

•  Cost effective

By performing multiple assays at one time, xMAP technology is designed to be cost effective for customers compared to 
competitive techniques such as ELISA or real-time PCR. By analyzing only those assays in which a customer is interested, 
xMAP is also more cost effective than most competing microarray technologies. In addition, microsphere-based assays are 
inexpensive compared to other technologies, such as chip based microarrays.

Two  types  of  microspheres,  polystyrene  microspheres  and  polystyrene  magnetic  microspheres,  are  both  fundamental 
components of the xMAP technology. We purchase and manufacture microspheres and, in a proprietary process, dye them with 
varying intensities of proprietary dyes to achieve up to 500 distinct colors. The specific dye proportions permit each color-coded 
microsphere to be readily identified based on its distinctive fluorescent signature. Our customers create assays by attaching different 
biochemical reactants to each distinctly colored microsphere set. These unique reactants bind, or capture, specific substances 
present in the test sample.  The microsphere sets can then be combined in test panels as required by the user, with a maximum of 
500 tests per panel.  Customers can order either standard microspheres or magnetic microspheres.

To perform an assay using xMAP technology on our systems, a researcher attaches biomarker detectors such as antibodies or 
nucleic acid oligos to one or more sets of color-coded microspheres, which are then mixed with a test sample. This mixture is 
injected into the xMAP analyzer such as the Luminex 200 instrument where the microspheres pass single-file in a fluid stream 
through two laser beams. The first laser excites the internal dyes that are used to identify the color of the microsphere and the test 
being performed on the surface of the microsphere. The second laser excites a fluorescent dye captured on the surface of the 
microspheres that is used to detect the result of the assay taking place. Our proprietary optics, digital signal processors and software 
record the fluorescent signature of each microsphere and compare the results to the known identity of that color-coded microsphere 
set. The results are analyzed and displayed in real-time with data stored on the computer database for reference, evaluation and 
analysis.

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, bio-defense, food safety and biomedical research.

Our xTAG and MultiCode Technologies

Our xTAG technology consists of several components including multiplexed PCR or target identification primers, DNA Tags, 
xMAP microspheres and data analysis software.  xTAG technology permits the development of molecular diagnostic assays for 
clinical use by hospital and reference laboratories.  xTAG technology has been applied, in particular, to human genetic assays, 
pharmacogenetic assays and infectious disease assays.

Our MultiCode technology is based upon a unique assay chemistry that is a flexible platform for both real-time PCR and 
multiplex PCR-based applications. MultiCode-based PCR assays are primarily used for the detection of infectious diseases and 
genetic-based conditions.  We have multiple molecular diagnostic assays based on the MultiCode chemistry. MultiCode products 
are based upon the unique MultiCode bases, isoC and isoG. The synthetic isoC:isoG DNA base pair differs from the naturally 
occurring base pairs in its hydrogen bonding pattern.  As a result, the MultiCode bases, isoC and isoG, can only pair with each 
other, but can co-exist with naturally occurring nucleotide pairs.  This property enables site-specific incorporation of the isobases 
during amplification.  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.

We have multiple assay development activities ongoing and these activities are focused in the areas of infectious disease, 
human genetics, and pharmacogenomics.  In the fourth quarter of 2015, we received FDA clearance for our ARIES® system and 
ARIES® HSV 1&2 Assay as well as our NxTAG Respiratory Pathogen Panel (RPP) Assay, and will submit additional assay products 
to the FDA for clearance to expand our ARIES® system test menu.  We have plans to submit additional assay products to regulatory 
authorities in 2016, including the FDA and foreign equivalents, for clearance in order to comply with established guidelines across 
the jurisdictions in which we participate.  

Business Strategy 

Our Company’s current focus is the transition from a technology-based tools company to a market-based diagnostic company 
and the establishment of Luminex as a market leader in the molecular diagnostic market.  To achieve these objectives, we have 
implemented and are pursuing the following strategies:

• 

Focus on key markets

We have identified the following key market segments: (i) molecular infectious disease, (ii) genetic or inherited disease, (iii) 
human leukocyte antigen (HLA) transplant diagnostics, (iv) pharmacogenetic testing, (v) immunodiagnostics, (vi) life sciences 
research and (vii) bio-defense, or bio-threat testing.  We will continue to employ a combination of a partnership-driven business 
model and a product-driven business model focused on selected market segments and assay applications.

•  Develop and deliver market-leading molecular diagnostic platforms and assays

Our research and development and our acquisitions have expanded the breadth of technology and solutions we offer our 
customers to meet their needs.  We acquired the MultiCode RTx real-time PCR technology for both quantitative and qualitative 
low-plex real-time PCR assays and the GenturaDx IDbox sample to answer platform, which is compatible with our MultiCode 
RTx technology, to provide our customers with a complete system for their real-time PCR assays. The GenturaDx IDbox was 
further developed and launched as the ARIES® system.  A key focus currently is the development of additional assay products 
for our ARIES® system.  The ARIES® system, when combined with our proprietary real-time PCR chemistry and a new menu 
of highly automated assays that we are developing, is designed to offer a differentiated, easy to use diagnostic solution.  The 
ARIES® system is designed to help clinical diagnostic laboratories overcome their daily challenges: minimizing healthcare 
cost increases while maintaining the overall quality of healthcare, the scarcity of highly trained laboratory personnel and 
limited lab bench space.  The ARIES® system offers barcode-based data entry, an efficient workflow, a slim design that occupies 
minimal  bench  space,  universal  assay  protocols  that  enable  true  walkaway  automation  and  ability  to  simplify  laboratory 
developed tests (LDTs).

•  Develop next generation products 

We have focused resources on improving the simplicity and ease of use of our multiplex products through the development 
of a new version of our multiplex PCR technology.  This new NxTAG chemistry enables customers to experience streamlined 
workflow without sacrificing throughput.  We recognize that the crucial aspect of our current technology that we want to 
preserve for our larger customers is the ability to process anywhere from 1 to 96 patients in a single batch.  This throughput 
flexibility and capacity is a crucial aspect for tests like our xTAG Respiratory Viral Panel (RVP), in which seasonality and 
local outbreaks can cause testing volumes to surge unpredictably.  We offer the convenience of a one-step workflow with the 
throughput of a batch-based system.  In addition, products using this new chemistry are expected to have the convenience of 
room temperature shipping and storage.  We released our NxTAG RPP product in 2015.  Additionally, we continue pursuing 
projects such as the development of consumables, automation, software and the expansion and enhancement of our multiplexing 
capabilities to advance our technologies and market acceptance. 

5

 
 
We have developed a full range of multiplexing instruments and consumables to cover a broad range of customer applications 
and budgets.  We have developed, and continue to improve, our proprietary chemistries for our multiplex assays in areas such 
as human genetic testing, personalized medicine testing and infectious disease testing. All of these technology solutions provide 
our customers with a breadth of innovative solutions to meet their many testing needs.

In the fourth quarter of 2015, we launched our sample to answer platform, ARIES® system.  We also received FDA clearance 
for the ARIES® HSV 1&2 Assay in the fourth quarter of 2015.

In addition, we are collaborating with industry participants, biomedical research institutions and government entities to develop 
additional products on our platform. We continuously consider other adjacent markets where our platform and assay offerings 
would be beneficial. 

•  Actively pursuing acquisitions that could accelerate our business strategies

We utilize analytical tools and an evaluation template to assess potential acquisition targets to accelerate our business strategies 
in the key markets described above. This approach led to several successful acquisitions historically, including the acquisition 
of GenturaDx in 2012, which is the foundation of our ARIES® system. We actively evaluate opportunities to enhance our 
capabilities or our access to targeted markets or technologies, or provide us other advantages in executing our business strategies 
in our key markets.

•  Continue to develop the partnership channel focused in select key markets

As of December 31, 2015, 48 of our 73 strategic partners have developed and commercialized xMAP based assay products 
and are paying royalties to us.  We also have strategic partners who distribute Luminex products.  During 2015, the 48 strategic 
partners who have commercialized xMAP based assay products accounted for approximately 68% of our total revenue and 
all of our strategic partners represented approximately 73% of our total revenue. We intend to continue pursuing opportunities 
to expand market acceptance of xMAP technology through development, marketing and distribution partnerships with leading 
companies in the life sciences markets. By leveraging our strategic partners’ market positions and utilizing their distribution 
channels and marketing infrastructure, we believe we can continue to expand our installed instrument base.  Furthermore, our 
partners’ investments in research and development for xMAP applications provide Luminex xMAP customers with more assay 
product options than any one company or Luminex could develop and commercialize individually.

We will continue to focus our commercialization efforts through our strategic partners covering large sectors of the life science 
research market where Luminex believes it has competitive advantages over alternative technologies and approaches. We 
define strategic partners as those companies in the life sciences markets that develop and distribute assays and tests on xMAP 
technology or may only distribute our xMAP technology based systems and consumables.  With our partners’ support and 
through  our  direct  commercial  efforts  in  the  molecular  diagnostics  clinical  laboratory  segment,  we  have  targeted  major 
pharmaceutical companies, large clinical laboratories, research institutions and major medical institutions for our principal 
marketing efforts. We believe these customers provide the greatest opportunity for maximizing the use of xMAP based products 
and continued adoption by these industry leaders will promote wider market acceptance of our xMAP technology. 

Products

perform rapid, multi-analyte profiles under the control of a Windows®-based personal computer and our proprietary software.

6

 
 
 
MAGPIX®.  The MAGPIX system is a versatile multiplexing analyzer capable of performing qualitative and quantitative 
analysis of proteins and nucleic acids in a variety of sample matrices.  This system can perform up to 50 tests in a single reaction 
volume, reducing sample input, reagents and labor while improving productivity.  MAGPIX is based on an innovative detection 
mechanism that uses LEDs and a charge-coupled device (CCD) imaging system, rather than the lasers and detection mechanisms 
used in our flow cytometry-based instruments.

ARIES®.  The ARIES® system is a sample to answer real-time PCR platform. The ARIES® system uses internal barcode 
scanning and other advanced features to minimize operator errors. Two independent modules each support from one to six cassettes, 
allowing for both STAT and Batch testing. The ARIES® system can run both IVD assays and MultiCode ASRs simultaneously 
with a common Universal Assay Protocol. An integrated touchscreen computer eliminates the need for a separate computer, stand-
alone keyboard and mouse; thus maximizing valuable bench space. 

Consumables

MicroPlex® Microspheres.  Our xMAP systems use polystyrene microspheres that are approximately 5.6 microns in diameter. 
We dye the microspheres in sets with varying intensities of a red and a near infrared dye to achieve up to 100 distinct color sets.  
Each microsphere can carry the reagents of an enzymatic, genetic or immunologic assay.

MagPlex®  Microspheres.  These  microspheres  feature  super-paramagnetic  properties  that  make  them  ideal  for  running 
automated xMAP-based assays.  We dye the microspheres in sets with varying intensities of a red and a near infrared dye to achieve 
up to 500 distinct color sets.  These microspheres can be moved or held in place by a magnetic field. Many automated systems 
utilize magnetic properties to automate the performance of the assay. Automating sample testing using MagPlex microspheres on 
a robotic sample preparation system decreases hands-on technician time, improves precision and streamlines workflow.

xTAG® Microspheres.  These dyed microspheres are linked to a set of 100 proprietary nucleic acid capture sequences providing 
a “universal array” for DNA and RNA work.  They are designed for conducting genotyping and other nucleic acid-based experiments 
in the life sciences, pharmaceutical and clinical diagnostic markets. When used in conjunction with our Luminex systems, the 
xTAG microspheres are designed to simplify the molecular assay development process and increase assay flexibility. The xTAG 
microspheres may be used by customers to develop LDT assays and are the chemistry used for the Luminex xTAG assays. 

SeroMAP™  Microspheres.  These  100  distinct  sets  of  microspheres  are  designed  for  specific  protein  based  serological 

applications.  Certain Luminex partners use this product for enhanced sensitivity in serum-based assays.

Calibration and Control Microspheres.  Calibration microspheres are microspheres of known fluorescent light intensities 
used  to  calibrate  the  settings  for  the  classification  and  reporter  channel  for  the  Luminex  systems.  Control  microspheres  are 
microspheres that are used to verify the calibration and optical integrity for both the classification and reporter channels for the 
various systems.

ARIES® Cassettes.  ARIES® cassettes are self-contained assay consumables designed to run a fully automated, sample to 
answer molecular assay on the ARIES® system.  The cassettes make use of proprietary injection-molded parts, as well as MultiCode 
and other reagents, to perform automated extraction, purification, elution, amplification and testing of nucleic acid testing from a 
variety of different sample types.

Software

xPONENT®.  Our  xPONENT  software  is  included  in  all  of  our  xMAP  instruments  and  enhances  both  ease-of-use  and 
automation capabilities expanding xMAP functionality in our core markets.  The software suite incorporates important features, 
all designed to simplify laboratory workflow and increase productivity, including enhanced security (21 CFR Part 11 compliance 
and electronic signatures), integration capabilities that allow customers to transmit and receive data from Laboratory Information 
Systems (LIS/LIMS), integration with the most popular automated sample preparation systems, the ability to run magnetic bead 
applications and touch-screen capability. xPONENT is sold on new Luminex 100, 200, FLEXMAP 3D, and MAGPIX systems 
and is available as an upgrade to the existing Luminex systems in the marketplace.

Assay Product Families

A product family consists of two or more assay products which are focused on similar or related markets.  Each assay consists 
of a combination of chemical and biological reagents and our proprietary bead technology used to perform diagnostic and research 
assays on samples.  As of February 23, 2016 the following product families are commercially available:

7

 
 Respiratory Viral Family

This family of products includes xTAG RVP, xTAG RVP FAST and NxTAG RPP, the newest version of the original RVP 
assay with greatly simplified workflow and time to results.  These IVD products enable our laboratory end users to identify the 
causative agent for respiratory infections, a major cause of illness and mortality globally, for physicians and their patients.

Gastrointestinal Pathogen Detection Family

The xTAG Gastrointestinal Pathogen Panel assay enables laboratory end users to identify the pathogens causing infectious 

gastroenteritis, which is a major cause of morbidity and mortality globally.

MultiCode Assays and Products Family

This product family includes our FDA-cleared HSV 1&2 Assay as well as a number of analyte specific reagents and other 
products.  These products are generally designed to detect infectious agents in clinical samples using our proprietary MultiCode 
RTx real-time PCR chemistry. 

ARIES® Assays and Products Family

This product family includes our FDA-cleared ARIES® HSV 1&2 Assay, as well as other ARIES® assays in development. 

Cystic Fibrosis Family

These FDA-cleared and Conformité Européenne (CE) marked IVD kits include the first-ever IVD assays for cystic fibrosis 
(CF)  genotyping.  Current  recommendations  by  the  American  College  of  Medical  Genetics  and  the  American  College  of 
Obstetricians and Gynecologists include screening for 23 mutations in the CF transmembrane conductance regulator gene. The 
xTAG CF kits screen for these mutations in addition to a variety of other important CF mutations, commonly found in the ethnically 
diverse North American and European populations.  These kits are typically used for screening newborns and for diagnosing adult 
carriers of the CF gene.

Pharmacogenetics Product Family

This product family includes assays used to determine the drug metabolism status of individuals for specific medications.  All 
products include genotyping of genes encoding different cytochrome P450 drug metabolizing enzymes.  This type of  information 
is typically used to determine if a patient will need a lower or higher dose of a specific drug, or whether the patient should be 
switched to a different medication altogether.  Two of the products in this category are the FDA-cleared CYP2D6 and CYP2C19 
assays used for identifying patients with variants that affect the metabolism and efficacy of some pharmaceutical compounds.

Specialty Product Family and Instrumentation

This family of products includes a variety of assays targeted towards specialty, niche markets.

In addition to the commercially available assays, we are an original equipment manufacturer (OEM) of custom reagents and 

instrumentation for certain of our customers.

Sales and Marketing

Our sales and marketing strategy is to expand the installed base and utilization of xMAP, xTAG and MultiCode product lines, 
as well as drive a successful launch for our newest products: NxTAG RPP and ARIES® system.  We are focused on generating 
recurring revenues from the sale of Luminex developed assays, microspheres and other consumables, as well as from royalties on 
kits and testing services developed or performed by partners. We have two key elements to our sales and marketing strategy: i) 
marketing internally developed assays directly to end users and ii) building and maintaining long-term relationships with Luminex’s 
strategic partners. Luminex's strategic partners include clinical diagnostic, pharmaceutical and life sciences companies that develop 
applications and/or perform testing using our technology platforms.  Some partners also distribute the xMAP systems to their 
customers. 

We  sell  the  xMAP  and  MultiCode  product  lines  primarily  through  a  direct  sales  channel  instead  of  through  distributors.  
Building a direct relationship with customers is a critical component of Luminex's sales and marketing strategy to launch new, 
innovative products such as NxTAG RPP and ARIES® system.  NxTAG RPP is a next generation product to replace the successful 
xTAG RVP assay. NxTAG RPP offers a streamlined workflow and enhanced product performance to customers.  The ARIES®
system program began with the acquisition of GenturaDx in July 2012 to secure a real-time PCR system for the previously acquired 
EraGen MultiCode product line.  After the acquisition of GenturaDx, we obtained customer feedback that ultimately transformed 
the GenturaDx IDbox into the ARIES® system.  Critical inputs of customer feedback resulted in a system redesign to better meet 
customer needs, including eliminating the external computer in lieu of an integrated touchscreen.  The ARIES® system takes up 
less  bench  space  than  competitive  systems.  In  addition,  the  unique  cassette  design  and  off  instrument  user  defined  protocol 
application  enables  customers  to  run  LDTs  and ASRs  along  with  their  IVD  assays.    Finally,  SYNCTTM,  an  innovative  data 
management software solution that compiles data from multiple ARIES® systems and xMAP systems, was released at the end of 
2015.  Enabling user defined protocols will accelerate Luminex's menu pipeline, and SYNCT meets customer needs in the laboratory, 
assisting laboratories to better leverage their data to decrease laboratory costs and improve patient care.

Outside  of  Luminex's  direct  molecular  diagnostic  business,  we  continue  to  work  with  strategic  partners  as  the  primary 
distribution channel for our xMAP systems, and we will continue to pursue new partnerships focusing on partners with market 
presence in the key partner segments described above.  Some of our strategic partners develop application-specific kits for use on 
our xMAP systems that they, in turn, sell to their customers, thereby generating royalties for us. Certain strategic partners also 
perform testing services for third parties using our xMAP products, which also results in royalty revenue.  Luminex also contracts 
with distributors to purchase and resell the xMAP systems and consumables in geographic or application-specific areas not covered 
by strategic partners. 

We update our strategic partner listing regularly to reflect results of partner consolidations due to mergers and acquisitions, 
commercial sales inactivity, as well as termination or expiration of existing non-performing partner agreements.  As of December 31, 
2015, we had 73 strategic partners, compared to approximately 66 strategic partners as of December 31, 2014.  During 2015, 48
strategic partners with commercialized products utilizing xMAP technology submitted royalties. As of December 31, 2015, 48 of 
these strategic partners with commercialized products remain, of which 26 companies principally serve the clinical diagnostics 
market and 22 companies principally serve the life science research market. Revenues through these commercialized, royalty-
submitting, strategic partners constituted 68% of our revenues for 2015. We also believe our strategic partners provide us with 
complementary capabilities in product development, regulatory expertise and sales and marketing. By leveraging our strategic 
partners’ assay development capabilities, customer relationships and distribution channels, we believe that we can continue to 
achieve measurable market penetration and product adoption.  Our remaining partners are in various stages of development and 
commercialization of products that incorporate our technology.

We also serve as an OEM provider for certain strategic partners that choose to sell components of the xMAP product line as 

an embedded system under their own branding and marketing efforts. 

Customers

In each of the last three years, one or more customers or partners each accounted for more than 10% of our total revenues.  
Laboratory Corporation of America (LabCorp) accounted for 24%, 21% and 18% of our total revenues in 2015, 2014 and 2013, 
respectively.  Thermo Fisher Scientific, Inc. accounted for 13%, 17% and 17% of our total revenues in 2015, 2014 and 2013, 
respectively.  No other customer or partner accounted for more than 10% of our total revenues in 2015, 2014 or 2013; however, 
Bio-Rad Laboratories, Inc. accounted for 8%, 7% and 9% of our total revenues in 2015, 2014 and 2013, respectively. The loss of 
any of these customers or partners could have a material adverse effect on our business, financial condition and results of operations.

International Operations

We currently sell our products to a number of customers outside the United States, primarily including customers in Canada, 
Europe and the Asia-Pacific region.  For the annual periods ended December 31, 2015, 2014 and 2013, foreign sales to customers 
totaled $37.3 million, $39.0 million, and $35.1 million, respectively, representing 16%, 17% and 16%, respectively, of our total 
revenues for such periods.  We have foreign subsidiaries in Canada, the Netherlands, the People’s Republic of China, Japan, and 
Hong Kong, which increase our international support, service and marketing capabilities.  Sales to territories outside of the U.S. 
are primarily denominated in U.S. dollars.  We believe that our activities in some countries outside the U.S. involve greater risk 
than our domestic business due to the foreign economic conditions, exchange rate fluctuations, local commercial and economic 
policies and political uncertainties.  See Note 17 to our Consolidated Financial Statements.

Technical Operations

Our Technical Operations Group provides technical assistance to our customers, our distributors, our strategic partners and 
their customers. Most of our technical operations personnel have experience as biologists, biochemists or electrical engineers and 
have extensive experience in academic, industrial and commercial settings. Cross training is a major focus, as is empowering group 
members to solve problems outside their primary assignment.

Remote Support

Our  technical  support  department  assists  users  primarily  through  a  toll-free  hotline,  internet  interface  and  e-mail 
communications.  We deliver “24/7” remote technical support with our staff based at our Austin and Toronto locations and from 
our European, Chinese and Japanese subsidiaries to better serve our customer base.  Personnel assist our distributors, strategic 
partners and customers in inquiry and complaint management related to Luminex products, system implementation and development 
of their assays. A comprehensive software and database system is utilized to track customer interactions, follow trends and measure 
utilization. The information is categorized and presented to management for regular review. 

Training

Through  our  training  group,  we  offer  comprehensive  programs  in  basic  system  training,  advanced  assay  development, 
instrument field service and technical support functions. A significant part of our training material is now web-based and available 
online.  Our classroom training is delivered locally, with our staff based at our Austin, Toronto, European, Chinese or Japanese 
offices.  For larger customers who have many users, such as our strategic partners, training may be performed on-site at their 
locations. 

Field Support

We currently have field service and field application personnel based across North America, Europe, China and Japan in areas 
of our more significant system concentration.  In addition, several of our distributors and strategic partners provide their own field 
service and field application support. As we continue to expand our installed base, we believe a strong, reliable, efficient field 
support organization is crucial to maintaining a high level of customer satisfaction. 

Research and Development  

Our research and development groups work to develop next generation systems, chemistries, assays and software to provide 
new, innovative products to our customers.  Our research and development expense for the years ended December 31, 2015, 2014
and 2013, was $42.7 million, $43.1 million and $45.0 million, respectively, including customer-sponsored research funding of 
$0.4 million, $0.7 million and $0.8 million, respectively.

Our current research and development projects include:

•  New platform & technology development

We have continued the evolution of the ARIES® system for sample to answer molecular diagnostic automated testing. 
This involves continuing design and development of new instrument versions, consumables and software, as well as the 
development of new assay chemistries based on the ARIES® system.

10

• 

Simplified assay products

Our research and development group has been working on a pipeline of new assays for use on the ARIES® system.  These 
automated assays are primarily in the area of infectious disease testing.

We have also developed a new, easy-to-use chemistry for running multiplexed tests in 96-well plates.  This chemistry 
combines  our  xTAG  and  xMAP  technologies  into  a  simple  to  use,  closed-tube  format.   The  first  product  using  this 
streamlined format, the NxTAG RPP, launched in 2015. 

•  Partnership projects

Luminex is working with the Defense Threat Reduction Agency of the United States government to develop a tactical 
diagnostic instrument.  Luminex on occasion collaborates on other partnered research programs. 

Manufacturing 

Luminex has approximately 60,700 square feet of manufacturing space located at our principal executive offices in Austin, 
Texas.  We recently expanded this space to enable ARIES® system cassette automation.  In addition, we have approximately 10,000 
square feet of manufacturing space located in Madison, Wisconsin and approximately 6,000 square feet of manufacturing space 
located in Toronto, Canada.  

We  initially  certified  our  Quality  Management  System  (QMS)  to  the  ISO  9001:2000  standard  and  in  2010  updated  our 
certification to ISO 9001:2008.  ISO is an internationally recognized standard for quality management systems.  Subsequent audits 
by the registrar have been and will continue to be carried out at regular intervals to ensure we are maintaining our system in 
compliance with ISO standards.  Recertification is required every three years and we have been successfully recertified since 
obtaining our original ISO certification.  Also, we have our QMS certified to the ISO 13485:2012 Quality Management Standard 
and the Canadian Medical Devices Regulation (CMDR).  These standards include a special set of requirements specifically related 
to the supply of medical devices and related services.  Additionally, we manufacture to current FDA "Good Manufacturing Practice" 
requirements and our QMS is implemented in accordance with FDA Quality System Regulations (21 CFR 820).

Supply Chain

We have historically purchased many of the components and raw materials used in our products from numerous suppliers 
worldwide. For reasons of quality assurance, sole source availability or cost effectiveness, certain components and raw materials 
used in the manufacture of our products are available only from one supplier. We have worked closely with our suppliers to develop 
contingency  plans  to  assure  continuity  of  supply  while  maintaining  high  quality  and  reliability,  and  in  some  cases,  we  have 
established long-term supply contracts with our suppliers.  Due to the high standards and FDA requirements applicable to the 
manufacturing of our products, we may not be able to quickly establish additional or replacement sources for certain components 
or  materials.  In  the  event  that  we  are  unable  to  obtain  sufficient  quantities  of  raw  materials  or  components  on  commercially 
reasonable terms or in a timely manner, our ability to manufacture our products on a timely and cost-competitive basis may be 
compromised, which may have a material adverse effect on our business, financial condition and results of operations.

Instruments

Component suppliers and contract manufacturers provide certain components and component assemblies of our xMAP and 
ARIES® systems.  The remaining assembly and manufacturing of our systems are performed at our facility in Austin, Texas. The 
quality control and quality assurance protocols are all performed at our facility.  Parts and component assemblies that comprise 
our technology systems are obtained from a number of sources.  We have identified alternate sources of supply for several of our 
strategic parts and component assemblies.  Additionally, we have entered into supply agreements with most of our suppliers of 
strategic parts and component subassemblies to help ensure component availability and flexible purchasing terms with respect to 
the purchase of such components.  As of December 31, 2015, a total of 12,684 Luminex multiplexing analyzers had been shipped 
since inception. 

11

Microspheres

We procure our undyed, standard Microplex microspheres and manufacture our magnetic Magplex carboxylated polystyrene 
microspheres.  We synthesize our dyes and manufacture our dyed microspheres using a proprietary method in our Austin, Texas 
manufacturing facility in large lots.  We dye the microspheres with varying intensities of red and near infrared dyes to produce 
our  distinctly  colored  microsphere  sets.  We  currently  purchase  the  standard  polystyrene  microspheres  from  one  supplier,  in 
accordance with a supply agreement. We believe this agreement will help ensure microsphere availability and flexible purchasing 
terms with respect to the purchase of such microspheres. While we believe the microspheres will continue to be available from 
our supplier in quantities sufficient to meet our production needs, we believe our in-house manufacturing capabilities along with 
other potential suppliers would provide sufficient microspheres for us if given adequate lead-time to manufacture the microspheres 
to our specifications.

Assays and Reagents

Component  suppliers  and  contract  manufacturers  produce  certain  components  of  our  xMAP-based  and  MultiCode-based 
developed reagents. The remaining assembly and manufacturing of our developed kits are performed at one of our facilities in 
Austin, Texas; Toronto, Canada or Madison, Wisconsin.  The quality control and quality assurance protocols are all performed at 
our facilities.  Reagents, consumables and other raw material that comprise our kits are obtained from a number of sources. 

In addition to developed assay kits, increasing regulatory requirements coupled with rising demand for new clinical applications 
are driving demand for laboratory developed tests.   Our proprietary technologies and platforms offer a unique combination of 
flexibility and throughput, as our systems' open architecture, software and standard protocols allow our customers the ability to 
use our proprietary reagents to validate and verify a new test, while being able to utilize the same system to handle increasing 
volumes once the assay is commercialized. 

Competition

We  design  our  xMAP  systems  and  consumables  for  use  by  customers  across  the  various  segments  of  the  life  sciences, 
pharmaceutical and clinical diagnostic industries.  Our xTAG, NxTAG, MultiCode and ARIES® products are developed specifically 
for the molecular diagnostic segment.  Our competition includes companies marketing conventional testing products based on 
established technologies such as ELISA, real-time PCR, mass spectrometry, gene sequencing, biochips, arrays and flow-based 
technologies as well as companies developing their own advanced testing technologies. 

The pharmaceutical industry is a large market for the genomic, protein and high-throughput screening applications supported 
by xMAP technology. In each application area, Luminex faces a different set of competitors. Genomic and protein testing can be 
performed by products available from Affymetrix, Inc., Life Technologies Corporation (a Thermo Fisher Scientific, Inc. brand), 
Becton, Dickinson and Company, Illumina, Inc., Qiagen N.V., Meso Scale Discovery (a division of Meso Scale Diagnostics LLC), 
Quanterix Corporation and PerkinElmer, Inc., among others.

Our diagnostic market competitors include, among others, Abbott Laboratories, Life Technologies Corporation (a Thermo 
Fisher Scientific, Inc. brand), BioFire Diagnostics, Inc. (a bioMérieux company), Cepheid, GenMark Dx, Roche Diagnostics, 
Siemens Medical, Hologic, Inc., Alere, Inc., Quidel Corporation, Focus Diagnostics (Quest Labs) and Illumina, Inc.  Some of 
these companies have technologies that can perform a variety of established assays. In addition, certain of these companies offer 
integrated systems and laboratory automation that are designed to meet the need for improved work efficiencies in the clinical 
laboratory. 

Competition within the academic biomedical research market is highly fragmented. There are hundreds of suppliers to this 
market including, among others, Amersham Pharmacia Biotech, a part of GE Healthcare, Life Technologies Corporation (a Thermo 
Fisher Scientific, Inc. brand) and Becton, Dickinson and Company.

Intellectual Property

To establish and protect our proprietary technologies and products, we rely on a combination of patent, copyright, trademark 
and trade secret laws and confidentiality agreements.  We have filed for registration or obtained registration for trademarks used 
with our products and key technologies. 

12

 
We have implemented a strategy designed to optimize our intellectual property rights. For core intellectual property, we are 
pursuing  patent  coverage  in  the  United  States  and  those  foreign  countries  that  correspond  to  the  majority  of  our  current  and 
anticipated customer base. We currently own 364 issued patents worldwide, including over 131 issued patents in the United States. 
Other countries in which we have issued patents directed to various aspects and applications of our products and technology include 
France, Germany, the United Kingdom, Australia, Japan, Netherlands, Canada, Hong Kong and China, amongst others. In addition, 
our patent portfolio includes 199 pending patent applications in the United States and other foreign jurisdictions.  We believe our 
patents and pending claims provide, or will provide, protection for systems and technologies that allow real-time multiplexed 
analytical techniques for the detection and quantification of many analytes from a single sample. We also hold patents covering 
the precision-dyeing process used in the manufacture of our fluorescent microspheres and patents covering digital over-sampling 
to measure the area of a fluorescence pulse instead of “peak detection,” giving increased sensitivity with no lost events. In addition, 
multiple granted patents and pending applications describe aspects of Multicode technology, xTAG technology, the ARIES® system 
and NxTAG technology.

The source code for our proprietary software is protected as a trade secret and/or as a copyrighted work. Aspects of this 

software also are covered by an issued patent.   

We also rely on trade secret protection of our intellectual property. We attempt to protect our trade secrets by entering into 
confidentiality  agreements  with  strategic  partners,  third  parties,  employees  and  consultants.  Our  employees  and  third-party 
consultants also sign agreements requiring that they assign to us their interests in inventions and original works of expression and 
any corresponding patents and copyrights arising from their work for us.  See Item 1A, "Risk Factors - The property rights we rely 
upon to protect the technologies underlying our products may not be adequate to maintain market exclusivity.  Inadequate intellectual 
property protection could enable third parties to exploit our technologies or use very similar technologies and could reduce our 
ability to distinguish our products in the market."

Government Regulation

Our  products  are  generally  considered  medical  devices  and  are  subject  to  regulation  by  numerous  government  agencies, 
including the FDA and similar agencies outside the United States. To varying degrees, each of these agencies require us to comply 
with laws and regulations governing the development, testing, manufacturing, labeling, marketing, and distribution of our medical 
devices. Our business is also affected by the United States and foreign patient privacy laws, cost containment initiatives and 
environmental health and safety laws and regulations. The primary laws and regulations that are unique to our business are described 
below. 

Food and Drug Administration 

The development, testing, manufacturing, marketing, post-market surveillance, distribution, advertising and labeling of our 
products is subject to regulation in the United States by the FDA.  FDA regulations require that certain products have pre-marketing 
clearance  or  approval  by  the  FDA  and  require  certain  products  to  be  manufactured  in  accordance  with  the  FDA’s  “Good 
Manufacturing Practice” requirements.  This requires that some products be extensively tested, and all to be properly labeled to 
disclose test results, performance claims and limitations.  Unless an exemption applies, before we can introduce a new product 
into the U.S. market, we must obtain FDA clearance by premarket notification 510(k) or similar pathway, or obtain premarket 
approval (PMA). 

If we can establish that our product is “substantially equivalent” to a pre-amendment or previously cleared device for which 
the FDA has not called for premarket approvals, we may seek clearance from the FDA to market the product by submitting a 510
(k). The 510(k) requires the support of appropriate data, including, in some cases, clinical data establishing the claim of substantial 
equivalence to the satisfaction of the FDA. A number of 510(k) clearances for our products have been obtained.

Where a product is not deemed as substantially equivalent to a pre-amendment or previously cleared device, a more rigorous 
PMA process is required. This PMA process requires us to independently demonstrate that the new medical device product is safe 
and effective by collecting data regarding design, materials and human clinical data. Only if the FDA determines there is reasonable 
assurance that the medical device is safe and effective, will the FDA authorize the device’s commercial release. The PMA process 
is much more detailed, time-consuming and expensive than the 510(k) process.

Numerous post-marketing regulatory requirements apply for our products, including, certain recordkeeping and reporting 
requirements, such as FDA’s medical device and corrections/removal reporting regulations. The FDA enforces its requirements 
by inspection and market surveillance. FDA has authority to take various administrative and legal actions against us if we or our 
products fail to comply with relevant legal or regulatory requirements. Such could include warning letters, product seizures, product 
recalls or withdrawals and/or other civil or criminal sanctions.

13

 
We manufacture versions of the Luminex instruments for use with diagnostic assay kits that are available through our strategic 
partners. For FDA purposes, the Luminex systems are IVD cleared and are considered components of our partners’ kit products. 
Kits manufactured by our strategic partners used in conjunction with our technology, may be subject to clearance or approval 
before they can be marketed and sold and are generally subject to FDA requirements such as Good Manufacturing Practices and 
others. Our partners are also subject to a number of other requirements in the Food, Drug, and Cosmetic Act and its regulations, 
such as Good Clinical Practice requirements, Device Registration and Listing, and  compliance with the FDA's current Good 
Manufacturing Practice regulations. These regulations, also known as the Quality System Regulations, govern the methods used 
in, and the facilities and controls used for, the design, manufacture, packaging, labeling, servicing, installation and distribution of 
all finished medical devices intended for human use. Our strategic partners are also subject to other pre-market and post-market 
controls such as labeling, complaint handling, medical device reporting, corrections and removals reporting and record keeping 
requirements. Upon evidence of non-compliance with applicable regulations, FDA can detain or seize products, request or, in 
certain circumstances, require a recall, impose operating restrictions, enjoin future violations, recommend criminal prosecution to 
the  Department  of  Justice  and/or  assess  civil  and  criminal  penalties  against  our  strategic  partner,  us,  or  our  officers  and  our 
employees.  Other regulatory agencies may have similar powers. In addition, various federal and state statues and regulations 
govern or influence the manufacturing, safety, storage of our products and components as well as our record-keeping. There can 
be no assurance that such requirements will always be met without interruption, or that the FDA will file, clear or approve our 
strategic partners’ submissions. 

We also manufacture kit products intended for Research Use Only applications (not for diagnostic use), kits that are IVD 
cleared for diagnostic use (currently regulatory classification of Class I and II), and Investigational Use Only or clinical applications.  
Although certain products intended for research use only are not currently subject to clearance or approval by the FDA, research 
use only products fall under the FDA’s jurisdiction if they are used for clinical rather than research purposes. Further, even where 
a product is not otherwise subject to clearance or approval by the FDA, the FDA, in order to limit sales to those who use the 
products for research only, can determine the manner in which we can market and sell our products and/or the types of customers 
to which we can market and sell our products.

Consideration  of  Research  Use  Only  products  including  genetic  analysis  tools,  and  the  process  and  extent  of  regulating 
Laboratory Developed tests in which our technology may be used, is presently underway at the Agency.  The nature and extent of 
rule changes and policy initiatives, and its effects on present and future products, and impact on our business in this area cannot 
be predicted.

Laboratories  that  purchase  certain  of  our  products  are  subject  to  extensive  regulation  under  the  Clinical  Laboratory 
Improvement Amendments  of  1988  (CLIA),  requiring  laboratories  to  meet  specified  standards  in  areas  such  as  personnel 
qualifications, administration, participation in proficiency testing, patient test management, quality control, quality assurance and 
inspections. Adverse interpretations of current CLIA regulations or future changes in CLIA regulations could have an adverse 
effect on sales of any affected products.

Certain of our instruments use lasers to detect assay results. Therefore, we are required to ensure that these products comply 
with FDA regulations pertaining to the performance of laser products. The Radiation Control for Health and Safety Act, administered 
by the FDA, imposes performance standards and record keeping, reporting, product testing and product labeling requirements for 
devices that emit radiation.  These regulations are intended to ensure the safety of laser products by establishing standards to 
prevent exposure to excessive levels of laser radiation. There can be no assurance that the FDA will agree with our interpretation 
and implementation of these regulations.

Foreign Jurisdictions

Medical  device  laws  and  regulations  are  also  in  effect  in  many  countries  outside  of  the  United  States  ranging  from 
comprehensive pre-approval requirements for medical products, to simpler requests for product data or certification. The number 
and scope of these requirements is increasing. There can be no assurance that we, and our strategic partners, will be able to obtain 
any approvals that may be required to market xMAP technology products outside the United States.  In addition, we may incur 
significant initial and/or ongoing costs in obtaining or maintaining our foreign regulatory approvals.  Further, the export by us of 
products that have not yet been cleared for domestic commercial distribution is subject to FDA or other export requirements and/
or restrictions.

We have agreements relating to the sale of our products to government entities and, as a result, we are subject to various 
statutes and regulations that apply to companies doing business with the government. A failure to comply with these regulations 
could result in suspension of these contracts, or administrative or other penalties, and could have a material adverse effect on our 
ability to compete for future government contracts and programs.
14

      
We produce CE marked products, which are subject to a number of different European Union (EU) Directives, including, but 
not limited to, the In Vitro Diagnostic Devices Directive (98/79/EC). CE marking of our products is currently by self-declaration, 
not issued by a third party, based on the intended uses of our products. A product that is not CE marked is automatically considered 
to be non-compliant. The law is enforced through market surveillance by appointed national enforcement agencies. Imported 
products are checked for compliance at customs offices.

No in vitro device or accessory may be placed on the market or put into service unless it satisfies the essential requirements 
set forth in the IVDD. Devices considered to meet the essential requirements must bear the CE marking of conformity, placed by 
the manufacturer, when introduced on the market. A manufacturer placing devices on the market in its name must notify its national 
competent authorities. 

There can be no assurance that the EU member states will agree with our interpretation and implementation of these regulations 
as it pertains to classification of our products. The failure by us or our strategic partners to comply with the IVDD could have a 
material adverse effect on our business.

The State Food and Drug Administration, P.R. China (SFDA), is the government regulation authority in charge of safety 
management of drug, food, health food and cosmetics for the People’s Republic of China. The SFDA issues certificates that are 
required for registration and approval to import our products into China. Certificates are also subject to periodic recertification 
requirements.  We have received certificates for the “Luminex System,” which combines the Luminex 100 and Luminex 200 into 
one product, and for our MAGPIX system.

Failure by us, or our strategic partners, to comply with applicable current federal, state and foreign medical product laws and 
regulations could have a material adverse effect on our business. Federal, state and foreign regulations regarding the manufacture 
and sale of medical devices and components of such devices are continually subject to future changes. We cannot predict what 
impact, if any, such changes might have on our business, but any such change could have a material impact.

WEEE

The European Community Council Directive 2002/96/EC on Waste Electrical and Electronic Equipment (WEEE) outlines 
the  responsibility  for  the  disposal  of  waste  electrical  and  electronic  equipment.  Compliance  with  WEEE  is  placed  with  the 
manufacturers of such equipment.  Those manufacturers are required to establish an infrastructure for collecting WEEE, in such 
a way that users of electrical and electronic equipment from private households should have the ability of returning WEEE at least 
free of charge.  All Luminex-manufactured equipment is in compliance with this directive. We have been in compliance with the 
requirements since August 13, 2005, regarding the labeling and disposal of our products containing electronic devices in each of 
the EU member states where our regulated products are distributed. 

RoHS

RoHS stands for “The Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment” and 
implements EU Directive 2002/95, which bans the placing on the EU market of new electrical and electronic equipment containing 
more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl 
ether flame retardants. 

The Directive directly affects producers who manufacture or assemble electrical or electronic equipment in the EU, importers 
of electrical or electronic equipment from outside the EU and companies that re-brand electric producers as their own. The Directive 
applies to electrical and electronic equipment falling under the categories 1, 2, 3, 4, 5, 6, 7 and 10 set out in Annex IA of the WEEE 
Directive (2002/96/EC).  Equipment categories 8 and 9 defined in the WEEE Directive are currently outside the scope of the RoHS 
Directive.  Luminex IVD equipment is classified as category 8 (Medical Devices) in Annex IA of the WEEE Directive, which is 
not covered within the scope of the RoHS Directive.  Luminex research equipment is classified as category 9 (Monitoring and 
Control Instruments) in Annex IA of the WEEE Directive, which is not covered within the scope of the RoHS Directive.

Environmental 

We are subject to federal, state and local laws and regulations relating to the protection of human health and the environment. 
In the course of our business, we are involved in the handling, storage and disposal of certain chemicals and biohazards. The laws 
and regulations applicable to our operations include provisions that regulate the discharge of materials into the environment. Some 
of these environmental laws and regulations impose “strict liability,” rendering a party liable without regard to negligence or fault 
on the part of such party. Such environmental laws and regulations may expose us to liability for environmental contamination, 
including remediation costs, natural resource damages and other damages as a result of the conduct of, or conditions caused by, 
us or others or for acts that were in compliance with all applicable laws at the time such acts were performed. In addition, where 
contamination may be present, it is not uncommon for neighboring landowners and other third parties to file claims for personal 
injury, property damage and recovery of response costs. Although it is our policy to use generally accepted operating and disposal 
practices  in  accordance  with  applicable  environmental  laws  and  regulations,  hazardous  substances  or  wastes  may  have  been 
disposed or released on, under or from properties owned, leased or operated by us or on, under or from other locations where such 
substances or wastes have been taken for disposal. These properties may be subject to investigation, remediation and monitoring 
requirements under federal, state and local environmental laws and regulations. We believe that our operations are in substantial 
compliance with applicable environmental laws and regulations. However, failure to comply with these environmental laws and 
regulations may result in the imposition of administrative, civil and criminal penalties or other liabilities. We do not believe that 
we have been required to expend material amounts in connection with our efforts to comply with environmental requirements or 
that compliance with such requirements will have a material adverse effect upon our capital expenditures, results of operations or 
competitive  position.  Because  the  requirements  imposed  by  such  laws  and  regulations  may  frequently  change  and  new 
environmental laws and regulations may be adopted, we are unable to predict the cost of compliance with such requirements in 
the future, or the effect of such laws on our capital expenditures, results of operations or competitive position. Moreover, the 
modification  or  interpretation  of  existing  environmental  laws  or  regulations,  the  more  vigorous  enforcement  of  existing 
environmental laws or regulations or the adoption of new environmental laws or regulations may also negatively impact our 
strategic partners, which in turn could have a material adverse effect on us and other similarly situated component companies.

Other Government Regulations

Our operations in the United States are subject to various federal and state fraud and abuse laws, including, without limitation, the 
federal anti-kickback statute and state and federal marketing compliance laws. These laws may impact our operations directly or 
indirectly through our customers, and may impact, among other things, our proposed sales, marketing and education programs. 
In addition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct 
our business.  We are also subject to statutes in foreign jurisdictions that prohibit commercial bribery and certain activities with 
customers or potential customers.  The laws that may affect our ability to operate include the following foreign laws, federal laws 
and their counterparts at the state level in addition to various implementing regulations: 

•  the federal Anti-kickback Statute and state anti-kickback prohibitions; 

•  the federal physician self-referral prohibition, commonly known as the Stark Law, and state equivalents; 

•  the federal Health Insurance Portability and Accountability Act of 1996, as amended; 

•  the Medicare civil money penalty laws and exclusion provisions; 

•  the federal False Claims Act civil and criminal penalties and state equivalents; 

•  U. K. Bribery Act of 2010;

•  the Foreign Corrupt Practices Act, which applies to our international activities; and 

•  the Physician Payment Sunshine Act. 

Other

Based on the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act 
of 2010 (the "Health Reform Law"), the Internal Revenue Service (IRS) implemented a medical device excise tax of 2.3% of the 
sale price on non-exempt medical devices. This tax on manufacturers, producers and importers has not had, nor do we expect it 
to have, a material impact on our operations.  A two-year moratorium on this tax took effect on January 1, 2016 under the Protecting 
Americans from Tax Hikes Act of 2015.

16

Employees

As of February 23, 2016 and December 31, 2015, respectively, we had a total of 797 and 806 employees and contract employees, 
as compared with 745 as of December 31, 2014.  The year over year increase is primarily the result of the addition of sales and 
marketing employees focused on direct sales to our end customers, as well as personnel added related to production, regulatory 
clearance and quality control for our ARIES® system and our bead products and assays.  None of our employees are represented 
by a collective bargaining agreement, and we have not experienced any work stoppage. We believe that relations with our employees 
are good.

Seasonality

Worldwide sales, including U.S. sales, do not reflect any significant degree of seasonality; however, sales of our Respiratory 

Viral products have demonstrated seasonal fluctuations consistent with the onset and decline of influenza-like illnesses.

Segment Reporting

During the fourth quarter of 2014, following the appointment of our new CEO, Luminex evaluated its historical reporting 
segments: the Technology and Strategic Partnership (TSP) segment and the Assays and Related Products (ARP) segment. As a 
result of this evaluation and based upon how our Chief Executive Officer, as Chief Operating Decision Maker, and our management 
team collectively manages our business, we determined that the two former segments were so integrated and interrelated that they 
no longer provided an accurate representation of our business when reported separately.  Additionally, we also took actions to 
consolidate sales and service functions.  As a result, effective with the fourth quarter of 2014, we viewed and began presenting 
our  business  as  one  operating  segment.     Accordingly,  2013  information  has  been  restated  to  conform  to  the  2015  and  2014 
presentation.

Financial information relating to our business for the years ended December 31, 2015, 2014 and 2013 can be found in Item 
7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8 “Financial Statements 
and Supplementary Data.”

ITEM 1A. RISK FACTORS

If we do not introduce new products in a timely manner, we may lose market share and be unable to achieve revenue growth 
targets.

We sell many of our products in industries characterized by rapid technological change, frequent new product and service 
introductions and evolving customer needs and industry standards. Many of the businesses competing with us in these industries 
have significant financial and other resources to invest in new technologies, substantial intellectual property portfolios, substantial 
experience in new product development, regulatory expertise, manufacturing capabilities and established distribution channels to 
deliver products to customers. Our products could become technologically obsolete over time, or we may invest in technologies 
that do not lead to revenue growth or continue to sell products for which the demand from our customers is declining, in which 
case we may lose market share or not achieve our revenue growth targets. The success of our new product offerings will depend 
upon several factors, including our ability to:

•  accurately anticipate customer needs;

•  innovate and develop new technologies and applications;

•  obtain required regulatory clearances;

•  successfully commercialize new technologies in a timely manner; 

•  price our products competitively, and manufacture and deliver our products in sufficient volumes and on time; and

•  differentiate our offerings from our competitors' offerings.

Many of our products are used by our customers to develop, test and manufacture their products. We must anticipate industry 
trends and consistently develop new products to meet our customers' expectations. In developing new products, we may be required 
to make significant investments before we can determine the commercial viability of the new product. If we fail to accurately 
foresee our customers' needs and future activities, we may invest heavily in research and development of products that do not lead 
to significant revenue. We may also suffer a loss in market share and potential revenue if we are unable to commercialize our 
products in a timely and efficient manner.

If our current products and our products under development do not become widely used in the life sciences, pharmaceutical 
and clinical diagnostics industries, we may not be able to maintain or increase profitability.

Life sciences, pharmaceutical and clinical diagnostic service provider companies have historically conducted biological tests 
using  a variety of  technologies, including bead-based analysis.   The  commercial success  of  our products  depends upon  their 
widespread adoption as  methods to perform assays. In order to be successful, we must convince potential partners and customers 
to utilize our system instead of other competing products. Market acceptance depends on many factors, including our ability to:

•  timely and successfully launch our products under development;

•  manage trends relating to, or the introduction or existence of, competing products or technologies that may be more 

effective, cheaper or easier to use than our products and technologies;

•  operate in a highly competitive marketplace, including in the presence of competing products sold by companies with 

longer operating histories, more recognizable names and more established distribution networks;

•  convince  prospective  strategic  partners  and  customers  that  our  products  are  an  attractive  alternative  to  others  for 

pharmaceutical, research, clinical, biomedical and genetic testing and analysis; 

•  encourage these partners to develop and market products using our technologies;

•  manufacture products in sufficient quantities with acceptable quality and at an acceptable cost;

•  obtain and maintain sufficient pricing and royalties from partners on such Luminex products; and

•  place and service sufficient quantities of our products, including the ability to provide the level of service required in the 

life science and clinical diagnostics market segments.

20

Because of these and other factors, our products may not gain or sustain sufficient market acceptance to maintain or increase 
profitability.  Additionally, we may have to write off excess or obsolete inventory if sales of our products are not consistent with 
our expectations or if the demand for our products changes.

The life sciences industry is highly competitive and subject to rapid technological change, and we may not have the technologies 
and resources necessary to compete successfully. 

We compete with companies in the United States and abroad that are engaged in the development and production of similar 
products. We will continue to face intense competition from existing competitors and other companies seeking to develop and 
commercialize  new  technologies.  Many  of  our  competitors  have  access  to  greater  financial,  technical,  scientific,  research, 
marketing, sales, distribution, service and other resources than we do and may have longer operating histories or more recognizable 
brand names. These companies may develop technologies that are superior alternatives to our technologies or may be more effective 
at commercializing their technologies in products.

The life sciences industry is characterized by rapid and continuous technological innovation. We may need to develop new 
technologies for our products to remain competitive. One or more of our current or future competitors could render our present 
or future products or those of our partners obsolete or uneconomical by technological advances, including the introduction or 
existence of, competing products or technologies that may be more effective, cheaper or easier to use than our products and 
technologies. In addition, the introduction or announcement of new products by us or others could result in a delay of or decrease 
in sales of existing products as we await regulatory approvals, while customers evaluate these new products, or if customers choose 
to purchase the new products instead of legacy products. We may also encounter other problems in the process of delivering new 
products to the marketplace such as problems related to design, development, supply chain or manufacturing of such products, 
and as a result we may be unsuccessful in selling such products. Our future success depends on our ability to compete effectively 
against current technologies, as well as to respond effectively to technological advances by developing and marketing products 
that are competitive in the continually changing technological landscape.

Several companies provide systems and reagents for DNA amplification or detection. Life Technologies Corporation (a Thermo 
Fisher Scientific, Inc. brand) and F. Hoffman-La Roche Ltd. (Roche) sell systems integrating DNA amplification and detection 
(sequence detection systems) to the commercial market. Life Technologies Corporation  (a Thermo Fisher Scientific, Inc. brand), 
Roche, Abbott Laboratories, Becton Dickinson and Company, Qiagen N.V., Hologic, Inc., Meridian Bioscience, Inc., bioMérieux 
S.A., Illumina, Inc. and Quidel Corporation sell sequence detection systems, some with separate robotic batch DNA purification 
systems,  and  they  also  sell  reagents  to  the  clinical  diagnostics  market.  Other  companies  offer  molecular  diagnostic  tests. 
Additionally, we anticipate that in the future, additional competitors will emerge that offer a broad range of competing products. 

Currently, a limited number of direct customers and strategic partners account for a significant portion of our revenue and 
the loss of any one of these or their inability to perform to expectations could have a material adverse effect on our business, 
financial condition and results of operations.  Our success depends significantly on the establishment and maintenance of 
successful relationships with our direct customers and strategic partners. 

LabCorp, Thermo Fisher Scientific Inc., and Bio-Rad Laboratories, Inc., accounted for 45% of total revenue (24%, 13% and 
8%,  respectively)  in  the  twelve  months  ended  December 31,  2015.    For  comparative  purposes,  these  same  three  companies 
accounted for 45% of total revenue (21%, 17% and 7%, respectively) in the twelve months ended December 31, 2014 and 44%
of total revenue (18%, 17% and 9%, respectively) in the twelve months ended December 31, 2013.   No other customer accounted 
for more than 8% of total revenue during the twelve months ended December 31, 2015.  In total, for the years ended December 31, 
2015 and 2014, our top five customers accounted for 54% and 55%, respectively, of our total revenue.  The loss of any of our 
significant direct customers, strategic partners or the loss of a material portion of the sales to these customers or partners could 
have a material adverse effect on our growth and future results of operations. 

21

Delays in implementation, delays in obtaining regulatory approval, changes in strategy or the financial difficulty of our strategic 
partners for any reason could have a material adverse effect on our business, financial condition and results of operations.

 Our ability to enter into agreements with additional strategic partners depends in part on convincing them that our products   
can help achieve and accelerate their goals or efforts. We expend substantial funds and management efforts with no assurance that 
any  additional  strategic  relationships  will  result.  We  cannot  guarantee  that  we  will  be  able  to  negotiate  additional  strategic 
agreements in the future on acceptable terms, if at all, or that current or future strategic partners will not pursue or develop alternative 
technologies either on their own or in collaboration with others. Some of the companies we are targeting as strategic partners offer 
products competitive with our xMAP technology, which may hinder or prevent strategic relationships.  Delays in implementation 
of new products by our strategic partners, changes in their strategy, financial difficulties they experience, or delays in obtaining 
or their inability to obtain regulatory approval for their products could negatively affect our business.  Termination of strategic 
relationships, the failure to enter into a sufficient number of additional strategic relationships on favorable terms, or disputes with 
our partners could reduce sales of our products, lower margins on our products and limit the market demand for and acceptance 
of our products.

As we pursue the development and registration of  products, regulation by governmental authorities in the United States and 
other countries will be a significant factor in the development, testing, production, and marketing of such products. Products that 
we develop in the molecular diagnostic markets will be regulated as medical devices by the FDA and other global governmental 
authorities and may require either receiving clearance following a pre-market notification process prior to marketing. Obtaining 
the  requisite  regulatory  approvals  can  be  expensive  and  may  involve  considerable  delay.  Changes  to  the  current  regulatory 
framework, including additional or new regulations could arise at any time during the development or marketing of our products, 
which may negatively affect our ability to obtain regulatory approval of our products.

In most of our strategic partnerships we have granted non-exclusive rights with respect to commercialization of our products 
and technology.  

We expect that a significant portion of our future revenues will come from sales of our systems and the development and sale 
of kits utilizing our xMAP consumables by our strategic partners and from use of our xMAP products by our strategic partners in 
performing services offered to third parties. We believe that our strategic partners will have economic incentives to develop and 
market these products, but we cannot accurately predict future sales and royalty revenues because many of our existing strategic 
partner agreements do not include minimum purchase requirements or minimum royalty commitments.  Some of our existing 
strategic partner agreements contain minimum purchase requirements for certain years, but unless renegotiated, those minimum 
purchase requirements could and do expire.  In addition, we have no control with respect to our strategic partners’ sales personnel 
and how they prioritize products based on xMAP technology, nor can we control the timing of the development or release of 
products by our strategic partners. The amount of these revenues depends on a variety of factors that are outside our control, 
including the amount and timing of resources that current and future strategic partners devote to develop and market products 
incorporating our technology. Furthermore, the development and marketing of certain kits will require our strategic partners to 
obtain governmental approvals, which could delay or prevent their commercialization efforts. If our current or future strategic 
partners do not successfully develop and market products based on our technology and obtain necessary government approvals, 
our revenues from product sales and royalties could be significantly reduced.

The property rights we rely upon to protect the technologies underlying our products may not be adequate to maintain market 
exclusivity. Inadequate intellectual property protection could enable third parties to exploit our technologies or use very similar 
technologies and could reduce our ability to distinguish our products in the market.

Our success depends, in part, on our ability to obtain, protect and enforce patents on our technologies and products and to 
protect our trade secrets, including the intellectual property of entities we may acquire. Any patents we own may not afford full 
protection for our technologies and products. Others may challenge our patents and, as a result, our patents could be narrowed or 
invalidated. In addition, our current and future patent applications may not result in the issuance of patents in the United States 
or foreign countries. Competitors may develop products that are not covered by our patents. Furthermore, there is a substantial 
backlog of patent applications at the U.S. Patent and Trademark Office and certain patent offices in foreign jurisdictions, and the 
approval or rejection of patent applications may take several years.

We currently own 364 issued patents worldwide, including 131 issued patents in the United States. Other countries in which 
we have issued patents directed to various aspects and applications of our products and technologies include France, Germany, 
the  United  Kingdom, Australia,  Japan,  Netherlands,  Canada,  Hong  Kong  and  China,  amongst  others.  In  addition,  our  patent 
portfolio includes 199 pending patent applications in the United States and other foreign jurisdictions.  We also have patents 
covering key aspects of MultiCode and xTAG technology utilized in our assay products as well as our ARIES® system and NxTAG.

22

We seek to require employees, consultants, strategic partners and other third parties to execute confidentiality agreements. 
Our employees and third-party consultants also sign agreements requiring that they assign to us their interests in inventions and 
original expressions and any corresponding patents and copyrights arising from their work for us. In addition, we have implemented 
a patent process to file patent applications on our key technologies. However, we cannot guarantee that these agreements or this 
patent process will provide us with adequate protection against improper use of our intellectual property or disclosure of confidential 
information. In addition, in some situations, these agreements may conflict with, or be subject to, the rights of third parties with 
whom our employees, consultants or advisers have prior employment or consulting relationships. Further, others may independently 
develop  substantially  equivalent  proprietary  technology,  techniques  and  products  or  counterfeit  versions  of  our  products  or 
otherwise gain access to our trade secrets. Our failure to protect our proprietary information and techniques may inhibit or limit 
our ability to distinguish our products in the market.

In  order  to  protect  or  enforce  our  patent  rights,  we  may  have  to  initiate  legal  proceedings  against  third  parties,  such  as 
infringement suits or interference proceedings. These legal proceedings could be expensive, take significant time and/or divert 
management’s attention from other business concerns. These proceedings may cause us to lose the benefit of some of our intellectual 
property rights, the loss of which may inhibit or preclude our ability to distinguish our products in the market.  These proceedings 
also may provoke these third parties to assert claims against us. The patent position of companies like ours generally is highly 
uncertain, involves complex legal and factual questions and has recently been the subject of much litigation. No consistent policy 
has emerged from the U.S. Patent and Trademark Office or the courts regarding the breadth of claims allowed or the degree of 
protection afforded under patents like ours.

Our success depends partly on our ability to operate without infringing on or misappropriating the proprietary rights of others.

We have been (and from time to time we may be) notified that third parties consider their patents or other intellectual property 
relevant to our products. We may be sued for infringing the intellectual property rights of others, including claims with respect to 
intellectual property of entities we may acquire.  In addition, we may find it necessary, if threatened, to initiate a lawsuit seeking 
a declaration from a court that we do not infringe on the proprietary rights of others or that their rights are invalid or unenforceable. 
Intellectual property litigation is costly, and, even if we prevail, the cost of such litigation could affect our profitability. Furthermore, 
litigation is time-consuming and could divert management’s attention and resources away from our business. If we do not prevail 
in any litigation, we may have to pay damages and could be required to stop the infringing activity or obtain a license. Any required 
license may not be available to us on acceptable terms, if at all. Moreover, some licenses may be nonexclusive, and therefore our 
competitors may have access to the same technology licensed to us. If we fail to obtain a required license or are unable to design 
around a patent, we may be unable to sell some of our products, which could have a material adverse effect on our business, 
financial condition and results of operations.

We require collaboration with other organizations in obtaining relevant biomarkers, access to oligonucleotides and enzymes 
that are patented or controlled by others. If we cannot continue to obtain these items or identify freedom to operate opportunities, 
our business, financial condition and results of operations could be negatively affected.

Security breaches and other disruptions could compromise our information, expose us to liability and harm our reputation 
and business.

In the ordinary course of our business we collect and store sensitive data, including intellectual property, personal information, 
our  proprietary  business  information  and  that  of  our  customers,  suppliers  and  business  partners  and  personally  identifiable 
information of our customers and employees in our data centers and on our networks. The secure maintenance and transmission 
of this information is critical to our operations and business strategy. We rely on commercially available systems, software, tools 
and domestically available monitoring to provide security for processing, transmitting and storing this sensitive data.

23

Hackers may attempt to penetrate our computer systems or our third party IT service providers' systems and, if successful, 
misappropriate personal or confidential business information. In addition, an associate, contractor or other third-party with whom 
we do business may attempt to circumvent our security measures in order to obtain such information, and may purposefully or 
inadvertently cause a breach involving such information. While we continue to implement additional protective measures to reduce 
the risk of and detect cyber incidents, cyber-attacks are becoming more sophisticated and frequent, and the techniques used in 
such attacks change rapidly.  Despite our cybersecurity measures (including employee and third-party training, monitoring of 
networks and systems and maintenance of backup and protective systems) which are continuously reviewed and upgraded, the 
Company’s information technology networks and infrastructure may still be vulnerable to damage, disruptions or shutdowns due 
to attack by hackers or breaches, employee error or malfeasance, power outages, computer viruses, telecommunication or utility 
failures, systems failures, natural disasters or other catastrophic events.  Any such compromise of our, or our third party IT service 
providers' data security and any access, public disclosure or loss of personal or confidential business information could result in 
legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties, disrupt our 
operations, damage our reputation and customers’ willingness to transact business with us and subject us to additional costs and 
liabilities, any of which could adversely affect our business. 

Our success depends on our ability to service and support our products directly or in collaboration with our strategic partners.

To the extent that we or our strategic partners fail to maintain a high quality level of service and support for xMAP products, 
there is a risk that the perceived quality of our xMAP products will be diminished in the marketplace. Likewise, we may fail to 
provide the level, quantity or quality of service expected by the marketplace. This could result in slower adoption rates and lower 
than anticipated utilization of xMAP products which could have a material adverse effect on our business, financial condition and 
results of operations.

We expect our operating results to continue to fluctuate from quarter to quarter.

The sale of our instrumentation and assay products typically involves a significant technical evaluation and commitment of 
capital by us, our partners and the end user. Accordingly, the sales cycle associated with our products typically is lengthy and 
subject to a number of significant risks, much of which is beyond our control, including partners’ budgetary constraints, inventory 
management practices, regulatory approval and internal acceptance reviews. As a result of this lengthy and unpredictable sales 
cycle, our operating results have historically fluctuated significantly from quarter to quarter. We expect this trend to continue for 
the foreseeable future.

The vast majority of our system sales are made to our strategic partners. Our partners typically purchase instruments in three 
phases  during  their  commercialization  cycle:  first,  instruments  necessary  to  support  internal  assay  development;  second, 
instruments for sales force demonstrations; and finally, instruments for resale to their customers. As a result, most of our system 
placements are highly dependent on the continued commercial success of our strategic partners and can fluctuate from quarter to 
quarter as our strategic partners move from phase to phase. We expect this trend to continue for the foreseeable future. 

Our assay products are sometimes sold to large customers. The ordering and consumption patterns of these customers can 
fluctuate, affecting the timing of shipments and revenue recognition. In addition, certain products assist in the diagnosis of illnesses 
that are seasonal, and customer orders can fluctuate for this reason.

Because of the effect of bulk purchases, defined as the purchase of $100,000 or more of consumables in a quarter, and the 
introduction of seasonal components to our assay menus, we experience fluctuations in the percentage of our quarterly revenues 
derived from our highest margin items: consumables, royalties and assays. Our gross margin percentage is highly dependent upon 
the mix of revenue components each quarter. These fluctuations contribute to the variability and lack of predictability of both 
gross margin percentage and total gross profit from quarter to quarter. We expect this trend to continue for the foreseeable future.

Due to the early stage of the market for molecular tests, projected growth scenarios for our assays are highly volatile and are 
based on a number of underlying assumptions that may or may not prove to be valid, including our ability to be successful with 
our direct assay sales strategy.

24

We may be unsuccessful in implementing our acquisition strategy. We may face difficulties integrating acquired entities with 
our existing businesses. Our business may be harmed by prior or future acquisitions.

Acquisitions of assets or entities designed to accelerate the implementation of our strategic plan are an important element of 
our long-term strategy. We may be unable to identify and complete appropriate future acquisitions in a timely manner, or at all, 
and no assurance can be provided that the market price of potential business acquisitions will be acceptable. In addition, many of 
our competitors have greater financial resources than we have and may be willing to pay more for these businesses or selected 
assets. In the future, should we identify suitable acquisition targets, we may be unable to complete acquisitions or obtain the 
financing, if necessary, for these acquisitions on terms favorable to us. Potential acquisitions pose a number of risks, including, 
among others, that:

•  we may not be able to accurately estimate the financial effect of acquisitions on our business; 

• 

• 

• 

future acquisitions may require us to incur debt or other obligations, issue additional securities, incur large and immediate 
write-offs, issue capital stock potentially dilutive to our stockholders or spend significant cash, or may negatively affect 
our operating results and financial condition;

if we spend significant funds or incur additional debt or other obligations, our ability to obtain financing for working capital 
or other purposes could decline, and we may be more vulnerable to economic downturns and competitive pressures;

technological advancement or worse than expected performance of acquired businesses may result in the impairment of 
intangible assets;

•  we  may  be  unable  to  realize  the  anticipated  benefits  and  synergies  from  acquisitions  as  a  result  of  inherent  risks  and 
uncertainties, including difficulties integrating acquired businesses or retaining their key personnel, partners, customers or 
other key relationships, entering market segments in which we have no or limited experience, and risks that acquired entities 
may not operate profitably or that acquisitions may not result in improved operating performance;

•  we may fail to successfully obtain appropriate regulatory approval or clearance for products under development of our 

acquired businesses;

•  we may fail to successfully manage relationships with customers, distributors and suppliers;

• 

our customers may not accept products of our acquired businesses;

•  we may fail to effectively coordinate sales and marketing efforts of our acquired businesses;

•  we may fail to combine product offerings and product lines of our acquired businesses quickly and effectively;

•  we may fail to effectively enhance acquired technology and products to develop new products relating to the acquired 

businesses;

• 

• 

• 

an acquisition may involve unexpected costs or liabilities, including as a result of pending and future shareholder lawsuits 
relating to acquisitions or exercise by shareholders of their statutory appraisal rights, or the effects of purchase accounting 
may be different from our expectations;

an acquisition may involve significant contingent payments that may adversely affect our future liquidity or capital resources;

acquisitions and subsequent integration of these companies may disrupt our business and distract our management from 
other responsibilities; and

• 

the costs of unsuccessful acquisition efforts may adversely affect our financial performance.

Other risks of integration of acquired businesses include:

• 

• 

disparate information technology, internal control, financial reporting and record-keeping systems;

differences in accounting policies, including those requiring judgment or complex estimation processes;

25

• 

• 

• 

• 

• 

• 

new partners or customers who may operate on terms and programs different than ours;

additional employees not familiar with our operations;

unanticipated additional transaction and integration-related costs;

our current and prospective customers and suppliers may experience uncertainty associated with an acquisition, including 
with respect to current or future business relationships with us and may attempt to negotiate changes in existing business;

facilities or operations of acquired businesses in remote locations or potentially foreign jurisdictions and the inherent risks 
of operating in unfamiliar legal and regulatory environments; and

new products, including the risk that any underlying intellectual property associated with such products may not have been 
adequately protected or that such products may infringe on the proprietary rights of others.

If our direct selling efforts for our products are less successful than anticipated, our business expansion plans could suffer 
and our ability to generate revenues could be diminished.  In addition, our limited history in selling our molecular diagnostics 
products on a direct basis makes forecasting difficult.

We have a relatively small sales force compared to some of our competitors. If our direct sales force is not successful, or new 
additions to our sales team fail to gain traction among our customers, we may not be able to increase market awareness and sales 
of our products, or maintain historical sales levels. If we fail to establish our systems in the marketplace, it could have a negative 
effect on our ability to sell subsequent systems and hinder the planned expansion of our business. 

The commercial launch of the ARIES® system is the first Luminex system launch that has not been channeled through a 
partner.  The successful execution of this launch and adoption by our direct customers is critical to establishing an installed base 
of satisfied customers.  To the extent that these customers do not adopt the anticipated large menu of forthcoming ARIES® assays 
that have been a significant focus of Luminex's research and development efforts over the last two years, there is a significant risk 
that our investment in these assays may not pay off.  Additionally, we have made a significant investment in the Luminex customer 
service, support and direct sales force to support the ARIES® system launch.  The ability of Luminex to service, support and sell 
the ARIES® system directly, and not through a partner, may also fail to meet market expectations, which could have a material 
adverse effect on our business, financial condition and results of operations.

We transitioned to selling our molecular diagnostics products on a direct basis in 2013, so we only have a three year direct 
sales history.  As a result, we have limited historical experience forecasting the direct sales of our molecular diagnostics products. 
Our ability to produce product quantities that meet customer demand is dependent upon our ability to forecast accurately, plan 
production accordingly and scale our manufacturing efforts. 

Unfavorable economic conditions and the uncertain economic outlook may adversely impact our business, results of operations, 
financial condition or liquidity.

Global economic conditions could adversely affect our results of operations.  The credit markets and the financial services 
industry continue to experience volatility, both domestically and internationally.  These conditions not only limit our access to 
capital but also make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business 
activities, and they could cause U.S. and foreign businesses and consumers to slow spending on our products and services, which 
would delay and lengthen sales cycles. Some of our customers rely on government research grants to fund technology purchases.  If 
negative trends in the economy affect the government’s allocation of funds to research, there may be less grant funding available 
for certain of our customers to purchase technologies like those Luminex sells.  Certain of our partners and their and our customers 
may face challenges gaining timely access to sufficient credit or may otherwise be faced with budget constraints, which could 
result in decreased purchases of, or development of products based on, our products or in an impairment of their ability to make 
timely payments to us.  If our partners and our customers do not make timely payments to us, we may be required to assume 
greater credit risk relating to those customers, increase our allowance for doubtful accounts and our days sales outstanding would 
be negatively impacted.   Although we maintain allowances for doubtful accounts for estimated losses resulting from the inability 
of our customers to make required payments, and such losses have historically been within our expectations and the provisions 
established, we may not continue to experience the same loss rates that we have in the past given the current condition of the 
worldwide economy.  Additionally, these economic conditions and market turbulence may also impact our suppliers causing them 
to  be  unable  to  supply  in  a  timely  manner  sufficient  quantities  of  customized  components,  thereby  impairing  our  ability  to 
manufacture on schedule and at commercially reasonable costs.

26

If the governmental laws and regulations change in ways that we do not anticipate and if we fail to comply with laws and 
regulations that affect our business, we could be subject to enforcement actions, injunctions and civil and criminal penalties 
or otherwise be subject to increased costs that could delay or prevent marketing of our products. 

The production, testing, labeling, marketing and distribution of our products for some purposes, including products based on 
our technology are subject to governmental regulation by the FDA and by similar agencies in other countries. Some of our products , 
including those based on our technology for in vitro diagnostic purposes, are subject to clearance by the FDA prior to marketing 
for commercial use. To date, seven strategic partners have obtained such clearances. Others are anticipated. The process of obtaining 
necessary FDA clearances can be time-consuming, expensive and uncertain. Further, clearance may place substantial restrictions 
on the indications for which the product may be marketed or to whom it may be marketed. In addition, because some of our 
products employ laser technology, we are also required to comply with FDA requirements relating to radiation performance safety 
standards.

Periodically the FDA issues guidance documents that represent the FDA’s current thinking on a topic. These issues are initially 
issued in draft form prior to final rule generally with enforcement discretion for some grace period of time. Changes made through 
this process may impact the release status of products offered and our ability to market those products affected by the change.  For 
example, the FDA released on September 14, 2007 the final document “Guidance for Industry and FDA Staff Commercially 
Distributed Analyte Specific Reagents (ASRs): Frequently Asked Questions.” This guidance may limit or delay distribution of 
assays on our platform, including assays that we developed internally and distributed, to the extent additional regulatory clearance 
is required prior to distribution. 

Cleared medical device products are subject to continuing FDA requirements relating to, among others, manufacturing quality 
control and quality assurance, maintenance of records and documentation, registration and listing, import/export, adverse event 
and other reporting, distribution, labeling and promotion and advertising of medical devices. Our inability or the inability of our 
strategic partners to obtain required regulatory approval or clearance on a timely or acceptable basis could harm our business. In 
addition,  failure  to  comply  with  applicable  regulatory  requirements  could  subject  us  or  our  strategic  partners  to  regulatory 
enforcement action, including warning letters, product seizures, recalls, withdrawal of clearances, restrictions on or injunctions 
against marketing our products or products based on our technology and civil and criminal penalties.

Medical device laws and regulations are in effect within the United States and also in many countries outside the United 
States. These range from comprehensive device clearance requirements for some or all of our medical device products to requests 
for product data or certifications regarding the hazardous material content of our products. As a device manufacturer, we are 
required to report annually to the Centers for Medicare and Medicaid Services (CMS) any payments or transfers of value we have 
made to physicians and teaching hospitals and any physician ownership or investment interest in the company.  As part of the 
European Council Directive 2002/96 of February 13, 2003, we are expected to comply with certain requirements regarding the 
collection, recycling and labeling of our products containing electronic devices in each of the EU member states where our regulated 
products are distributed. While we are taking steps to comply with the requirements of WEEE, we cannot be certain that we will 
comply with the national stage implementation of WEEE in all member states. We continue to evaluate the necessary steps for 
compliance with regulations as they are enacted. These regulations include, for example, the Registration, Evaluation, Authorization 
and Restriction of Chemical substances, the RoHS Directive and the WEEE Directive enacted in the European Union which 
regulate the use of certain hazardous substances in, and require the collection, reuse and recycling of waste from, certain products 
we manufacture. This and similar legislation that has been or is in the process of being enacted in various countries may require 
us to re-design our products to ensure compliance with the applicable standards. These redesigns may impact the performance of 
our products, add greater testing lead-times for product introductions or have other similar effects. We believe we comply with 
all such legislation where our products are sold and we will continue to monitor these laws and the regulations being adopted 
under them to determine our responsibilities. In addition, the State of California adopted the Electronic Waste Recycling Act, 
effective January 1, 2007, which requires the California Department of Toxic Substances Control to adopt regulations to prohibit 
the sale of electronic devices in California if they are also prohibited from sale in the EU under the RoHS Directive because they 
contain certain heavy metals. The number and scope of these requirements are increasing and we will likely become subject to 
similar laws in other jurisdictions. Failure to comply with applicable federal, state and foreign medical device laws and regulations 
may harm our business, financial condition and results of operations. We are also subject to a variety of other laws and regulations 
relating to, among other things, environmental protection and workplace health and safety.

27

 
Our strategic partners and customers expect our organization to operate on an established quality management system compliant 
with FDA Quality System Regulations and industry standards, the In Vitro Diagnostic Directive 98/79/EC of 27 October 1998 
(Directive)  as  implemented  nationally  in  the  EU  member  states  and  industry  standards,  such  as  ISO  9000. We  became  ISO 
9001:2000 certified in March 2002 and self-declared our Luminex 100, Luminex 200, FLEXMAP 3D and MAGPIX instruments 
to the Directive.  Our devices are in conformity with Article 1, Article 9, Annex I (Essential Requirements), Annex III and the 
additional provisions of the Directive as of December 7, 2003. Subsequent audits are carried out annually to ensure we maintain 
our system in substantial compliance with ISO and other applicable regulations and industry standards. We became ISO 13485:2003 
and Canadian Medical Devices Conformity Assessment System (CMDCAS) certified in July 2005. Failure to maintain compliance 
with FDA, CMDCAS and EU regulations and other medical device laws, or to obtain applicable registrations where required, 
could reduce our competitive advantage in the markets in which we compete and also decrease satisfaction and confidence levels 
with our partners.

Our success depends on our ability to attract and retain our management and staff.

We depend on the principal members of our management and scientific staff, including our chief executive officer, Homi 
Shamir, and our operations, marketing, research and development, technical support, technical service and sales staff. The loss of 
services of key members of management could delay or reduce our product development, marketing and sales and technical support 
efforts. In addition, recruiting and retaining qualified scientific and other personnel to perform research and development, technical 
support, technical service and marketing and sales work will be critical to our success. There is a shortage in our industry of 
qualified management and scientific personnel, and competition for these individuals is intense. There can be no assurance that 
we will be able to attract additional and retain existing personnel necessary to achieve our business objectives.  

Our reliance on strategic partnerships makes forecasting difficult.

As a result of our reliance on our strategic relationships, it can be difficult to accurately forecast future operating results.     

Estimating the timing and amount of sales of our products is particularly difficult for the following reasons (among others):

•  we do not control the timing or extent of product development, marketing or sale of our products by our strategic partners;

•  we do not control the incentives provided by our strategic partners and distributors to their sales personnel;

•  we utilize a limited number of geographically focused distributors for a portion of our sales, including several of our key 
assay products and the loss of or nonperformance by these distributors could harm our revenues in the territories serviced 
by these distributors;

• 

• 

• 

a significant number of our strategic partners intend to produce clinical diagnostic applications that may need to be approved 
by the FDA or other regulatory bodies in jurisdictions outside of the United States;

certain strategic partners may have unique requirements for their applications and systems. Assisting the various strategic 
partners may strain our research and development and manufacturing resources. To the extent that we are not able to timely 
assist our strategic partners, the commercialization of their products will likely be delayed;

certain strategic partners may fail to deliver products that satisfy market requirements, or such products may fail to perform 
properly;

•  we  have  limited  access  to  partner  and  distributor  confidential  corporate  information. A  sudden  unexpected  change  in 
ownership or strategy or other material event due to information of which we are not currently aware could adversely impact 
partner purchases of our products; and

• 

partners tend to order in bulk prior to the production of new lots of their products and prior to major product development 
initiatives.  The frequency of these bulk purchases is difficult to predict and may cause large fluctuations in microsphere 
sales quarter to quarter. 

28

If third-party payors continue to increasingly restrict payments for healthcare expenses or fail to adequately pay for multi-
analyte testing, we may experience reduced sales which would hurt our business and our business prospects. 

Third-party payors, such as government entities and government-sponsored healthcare programs (e.g. Medicare, Medicaid, 
Tricare),  health  maintenance  organizations,  preferred  provider  organizations  and  other  private  or  commercial  insurers  are 
continually seeking to reduce healthcare expenses.  Increasingly, third-party payors are challenging the utilization of and prices 
charged for medical services, including clinical diagnostic tests. Some payors are attempting to contain costs by limiting coverage, 
reducing reimbursement and increasing patient cost-sharing obligations.  The federal government has implemented and continues 
to utilize cost-cutting strategies for government-sponsored healthcare programs, including coverage limitations and reimbursement 
rate reductions required by the Health Reform Law.  On September 25, 2015, CMS issued a proposed rule that would implement 
policy  changes  required  by  the  Protecting Access  to  Medicare Act  of  2014  (PAMA).  If  finalized,  the  proposed  rule  would 
significantly revise reimbursement through the Clinical Diagnostic Laboratory Test Payment System and would also establish a 
related data collection system.  This change will likely cause the government’s reimbursement rates to clinical diagnostic labs to 
trend down over time, as CMS will determine Medicare payment rates based on data collected about rates being paid by commercial 
insurance companies. CMS believes these rates are predominately lower than the current Medicare rates.  In some cases, commercial 
payors are influenced by government-sponsored healthcare programs and policies.  Therefore, coverage and reimbursement from 
commercial payors may be negatively impacted as a result of changes in government-sponsored healthcare programs.  Further, 
cost containment initiatives by governmental or educational entities or programs may reduce funding for genetic research and 
development activities and retard the growth of the genetic testing market. 

Without adequate coverage or reimbursement, consumer demand for tests could decrease. Decreased demand could cause 
our direct customers or strategic partners to reduce purchases or to cancel programs or development activities, which could cause 
sales of our products and services to fall. In addition, decreased demand could place pressure on us, or our direct customers and 
strategic partners, to lower prices on these products or services, resulting in lower margins. Reduced sales or margins by us, or 
our direct customers and strategic partners, would adversely affect our business, profitability and business prospects.  Failure to 
secure appropriate reimbursement in foreign jurisdictions could severely limit our ability to expand sales within these markets.

As we continue to expand our business, we may experience problems in scaling our manufacturing operations, or delays or 
component shortages that could limit the growth of our revenue.

As we continue to expand our manufacturing capabilities in order to meet our growth objectives, we may not be able to 
produce sufficient quantities of products or maintain consistency between differing lots of consumables. If we encounter difficulties 
in  scaling  our  manufacturing  operations  as  a  result  of,  among  other  things,  quality  control  and  quality  assurance  issues  and 
availability of components and raw material supplies, we will likely experience reduced sales of our products, increased repair or 
re-engineering costs due to product returns and defects and increased expenses due to switching to alternate suppliers, any of 
which could reduce our revenues and gross margins.

We presently outsource certain aspects of the assembly of our systems to contract manufacturers. Because of a long lead-time 
to delivery, we are required to place orders for a variety of items well in advance of scheduled production runs. We have increased 
our flexibility to purchase strategic components within shorter lead times by entering into supply agreements with the suppliers 
of these components. Although we attempt to match our parts inventory and production capabilities to estimates of marketplace 
demand, to the extent system orders materially vary from our estimates, we may experience continued constraints in our systems 
production and delivery capacity, which could adversely impact revenue in a given fiscal period. Should our need for raw materials 
and components used in production continue to fluctuate, we could incur additional costs associated with either expediting or 
postponing delivery of those materials. In an effort to control costs we have implemented a lean production system. Managing the 
change from discrete to continuous flow production requires time and management commitment. Lean initiatives and limitations 
in our supply chain capabilities may result in part shortages that delay shipments and cause fluctuations in revenue in a given 
period.

We currently purchase certain key components of our product line from a limited number of outside sources and, in the case 
of some components, a single source, and these components may only be available through a limited number of providers. We do 
not have agreements with all of our suppliers. While we currently believe that we will be able to satisfy our forecasted demand 
for our products, the failure to find alternative suppliers in the event of any type of supply failure at any of our current vendors at 
reasonably  comparable  prices  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations.  Additionally, we have entered into supply agreements with most of our suppliers of strategic reagents and component 
subassemblies  to  help  ensure  component  availability,  and  flexible  purchasing  terms  with  respect  to  the  purchase  of  such 
components.  If our suppliers discontinue production of a key component, we will be required to revalidate an effected product 
and may be required to resubmit a previously cleared product.  Our reliance on our suppliers and contract manufacturers exposes 
us to risks including:

29

• 

• 

• 

• 

• 

• 

the  possibility  that  one  or  more  of  our  suppliers  or  our  assemblers  that  do  not  have  supply  agreements with  us  could 
terminate their services at any time without penalty;

natural disasters such as earthquakes, tsunamis and floods that impact our suppliers;

the potential obsolescence and/or inability of our suppliers to obtain required components;

the potential delays and expenses of seeking alternate sources of supply or manufacturing services;

the inability to qualify alternate sources without impacting performance claims of our products;

reduced  control  over  pricing,  quality  and  timely  delivery  due  to  the  difficulties  in  switching  to  alternate  suppliers  or 
assemblers; and

• 

increases in prices of raw materials and key components.

Consequently, in the event that supplies of components or work performed by any of our assemblers are delayed or interrupted 

for any reason, our ability to produce and supply our products could be impaired.

If the quality of our products does not meet our customers’ expectations, our reputation could suffer and ultimately our sales 
and operating earnings could be negatively impacted.

In the course of conducting our business, we must adequately address quality issues associated with our products and services, 
including defects in our engineering, design and manufacturing processes, as well as defects in third-party components included 
in our products. Because our instruments and consumables are highly complex, the occurrence of defects may increase as we 
continue to introduce new products and services and as we rapidly scale up manufacturing to meet increased demand for our 
products and services. Although we have established internal procedures to minimize risks that may arise from product quality 
issues, there can be no assurance that we will be able to eliminate or mitigate occurrences of these issues and associated liabilities. 
In addition, identifying the root cause of quality issues, particularly those affecting reagents and third-party components, may be 
difficult, which increases the time needed to address quality issues as they arise and increases the risk that similar problems could 
recur. Finding solutions to quality issues can be expensive and we may incur significant costs or lost revenue in connection with, 
for example, shipment holds, product recalls and warranty or other service obligations. In addition, quality issues can impair our 
relationships with new or existing customers and adversely affect our brand image, and our reputation as a producer of high quality 
products could suffer, which could adversely affect our business, financial condition or results of operations.

Our operations in foreign countries expose us to certain risks inherent in doing business internationally, which may adversely 
affect our business, results of operations or financial condition.

We expect that revenue from U.S. sales will continue to represent the majority of our total revenue, but our future profitability 
will depend in part on our ability to grow and ultimately maintain our product sales in foreign markets, particularly in Asia and 
Europe.  In fiscal 2015, approximately 16% of our revenue was derived from sales to non-U.S. customers, with approximately 
7% of revenue from sales to customers in Europe.  As such, a significant slowdown in these foreign economies or lower investments 
in new infrastructure could have a negative impact on our sales. We also purchase a portion of the materials included in our products 
from overseas sources.  As a result of acquisitions and organic growth, we have operations and manufacturing facilities in foreign 
countries that expose us to certain risks. For example, fluctuations in exchange rates may affect our revenues, expenses and results 
of operations, as well as the value of our assets and liabilities as reflected in our financial statements. We are also subject to other 
types of risks, including the following:

• 

• 

• 

• 

changes in or interpretations of foreign law that may adversely affect our ability to sell our products, perform services or 
repatriate profits to the United States;

tariffs, customs and other barriers to importing/exporting materials and products in a cost effective and timely manner;

hyperinflation or economic or political instability in foreign countries;

imposition of limitations on  or increase of withholding and other taxes on remittances and other payments by foreign 
subsidiaries;

30

 
 
• 

• 

• 

• 

• 

conducting business in places where business practices and customs are unfamiliar and unknown;

difficulties in staffing and managing international operations;

the burden of complying with complex and changing foreign regulatory requirements; 

difficulties in accounts receivable collections; 

the imposition of restrictive trade policies, including export restrictions;

•  worldwide political conditions;

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the imposition of inconsistent laws or regulations;

reduced protection of intellectual property rights and trade secrets in some foreign countries;

the imposition or increase of investment requirements and other restrictions by foreign governments;

the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute;

uncertainties relating to foreign laws, including labor laws, and legal proceedings;

the burden of complying with foreign and international laws and treaties;

significant currency fluctuations; 

the burden of complying with and changes in international taxation policies;

having to comply with a variety of U.S. laws, including the Foreign Corrupt Practices Act; and

having to comply with U.S. export control regulations and policies that restrict our ability to communicate with non-U.S. 
employees and supply foreign affiliates, partners and customers.

Our international sales and purchases are subject to numerous U.S. and foreign laws and regulations, including, without 
limitation, tariffs, trade barriers, regulations relating to import-export control, technology transfer restrictions, the International 
Traffic in Arms Regulation promulgated under the Arms Export Control Act, the Foreign Corrupt Practices Act and the anti-boycott 
provisions of the U.S. Export Administration Act. If we fail to comply with these laws and regulations, we could be liable for 
administrative, civil or criminal liabilities, and in the extreme case, we could be suspended or debarred from government contracts 
or have our export privileges suspended, which could have a material adverse effect on our business.

International sales and purchases are also subject to a variety of other risks, including risks arising from currency fluctuations, 
collection issues and taxes. Our international sales are subject to variability as our selling prices become less competitive in 
countries with currencies that are declining in value against the U.S. dollar and more competitive in countries with currencies that 
are increasing in value against the U.S. dollar. In addition, our international purchases can become more expensive if the U.S. dollar 
weakens against the foreign currencies in which we are billed.

We have not entered into any foreign currency derivative financial instruments; however, we may choose to do so in the future 

in an effort to manage or hedge our foreign exchange rate risk.

The capital spending policies of our customers have a significant effect on the demand for our products.

Our  customers  include  clinical  diagnostic,  pharmaceutical,  biotechnological,  chemical  and  industrial  companies,  and  the 
capital spending policies of these companies can have a significant effect on the demand for our products. These policies are based 
on a wide variety of factors, including general or local economic conditions, governmental regulation or price controls, resources 
available for purchasing research equipment, spending priorities among various types of analytical equipment and policies regarding 
capital expenditures during recessionary periods. Any decrease in capital spending by life sciences companies could cause our 
revenues to decline. As a result, we are subject to significant volatility in revenue. Therefore, our operating results can be materially 
affected (negatively and positively) by the spending policies and priorities of our customers.

31

If we become subject to claims relating to improper handling, storage or disposal of hazardous materials, we could incur 
significant cost and time to comply. 

Our research and development processes involve the controlled storage, use and disposal of hazardous materials, including 
biological hazardous materials. We are subject to foreign, federal, state and local regulations governing the use, manufacture, 
storage, handling and disposal of materials and waste products. We may incur significant costs complying with both existing and 
future environmental laws and regulations. In particular, we are subject to regulation by the Occupational Safety and Health 
Administration (OSHA) and the Environmental Protection Agency (EPA), and to regulation under the Toxic Substances Control 
Act and the Resource Conservation and Recovery Act in the United States. OSHA or the EPA may adopt regulations that may 
affect our research and development programs. We are unable to predict whether any agency will adopt any regulations that would 
have a material adverse effect on our operations. 

The risk of accidental contamination or injury from hazardous materials cannot be eliminated completely. In the event of an 
accident, we could be held liable for any damages that result, and any liability could exceed the limits or fall outside the coverage 
of our workers’ compensation insurance. We may not be able to maintain insurance on acceptable terms, if at all. 

If a catastrophe strikes our manufacturing or warehousing facilities, we may be unable to  manufacture or distribute our 
products for a substantial amount of time and we may experience inventory shortfalls, which would cause us to experience 
lost revenues. 

Our manufacturing facilities are located in Austin, Madison and Toronto. Although we have business interruption insurance, 
our facilities and some pieces of manufacturing equipment are difficult to replace and could require substantial replacement lead-
time. Various types of disasters, including tornadoes, fires, floods and acts of terrorism, may affect our manufacturing facilities. 
In the event our existing manufacturing facilities or equipment are affected by man-made or natural disasters, we may be unable 
to manufacture products for sale or meet customer demands or sales projections. If our manufacturing operations were curtailed 
or ceased, it would seriously harm our business. 

The "conflict minerals" rule of the SEC has caused us to incur additional expenses, could limit the supply and increase the 
cost of certain metals used in manufacturing our products, and could make us less competitive in our target markets. 

On August 22, 2012, the SEC adopted a rule requiring disclosure of specified minerals, known as conflict minerals, that are 
necessary to the functionality or production of products manufactured or contracted to be manufactured by public companies. The 
rule requires companies to obtain sourcing data from suppliers, engage in supply chain due diligence, and file annually with the 
SEC a specialized disclosure report. The rule could limit our ability to source at competitive prices and to secure sufficient quantities 
of certain minerals used in the manufacture of our products, specifically tantalum, tin, gold and tungsten, as the number of suppliers 
that provide conflict-free minerals may be limited. We may incur material costs associated with complying with the disclosure 
requirements, such as costs related to the determination of the origin, source and chain of custody of the minerals used in our 
products, the adoption of conflict minerals-related governance policies, processes and controls, and possible changes to products 
or sources of supply as a result of such activities. Within our supply chain, we may not be able to sufficiently verify the origins 
of the relevant minerals used in our products through the data collection and due diligence procedures that we have implemented, 
which may harm our reputation. Furthermore, we may encounter challenges in satisfying those customers that require that all of 
the components of our products be certified as conflict free, and if we cannot satisfy these customers, they may choose a competitor’s 
products. We continue to investigate the presence of conflict materials within our supply chain. 

If we become subject to product liability claims, we may be required to pay damages that exceed our insurance coverage.

Our business exposes us to potential product liability claims that are inherent in the testing, production, marketing and sale 
of biotechnological, human diagnostic and therapeutic products. Although we believe that we are reasonably insured against these 
risks and we generally have limited indemnity protections in our supplier agreements, there can be no assurance that we will be 
able to obtain insurance in amounts or scope sufficient to provide us with adequate coverage against all potential liabilities. A 
product liability claim in excess of our insurance coverage or a claim that is outside or exceeds our indemnity protections in our 
supplier agreements or a recall of one of our products would have to be paid out of our cash reserves. 

32

Our success depends on building and sustaining our technology infrastructure.

We are increasingly dependent on information technology to enable us to improve the effectiveness of our operations and to 
maintain financial accuracy and efficiency. If we do not allocate and effectively manage the resources necessary to build, implement 
and sustain the proper technology infrastructure, we could be subject to transaction errors, the inability to properly support and 
service our customers, processing inefficiencies, loss of customers, business disruptions or loss of or damage to intellectual property 
through security breach or cyber-attack, each of which could materially and adversely affect our business.

Our government contracts and administrative processes and systems related to such contracts are subject to audits and cost 
adjustments by the federal government, which could reduce our revenue, disrupt our business or otherwise adversely affect 
our results of operations. 

We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. 
Government contracts. A violation of specific laws and regulations could result in the imposition of fines and penalties or the 
termination of our contracts, as well as suspension or debarment. These fines and penalties could be imposed for failing to follow 
procurement integrity and bidding rules, employing improper billing practices or otherwise failing to follow rules relating to billing 
on cost-type contracts, receiving or paying kickbacks or filing false claims, among other potential violations. In addition, we could 
suffer serious reputational harm if allegations of impropriety related to such contracts were made against us. 

In addition, our contracts with the U.S. Government are subject to future funding and are subject to the right of the government 
to terminate the contracts in whole or in part for its convenience. There is pressure for the U.S. Government to reduce spending, 
and non-appropriation of funds or the termination for the government’s convenience of our contracts could cause our actual results 
of operations to differ materially and adversely from those anticipated.  Further, for U.S. Government contracts that include option 
years, the U.S. Government generally has the unilateral right to not exercise option periods, and may not exercise an option period 
if the agency is not satisfied with our performance on the contract or does not receive funding to continue the program, among 
other reasons.    

Further, federal government agencies, including the Defense Contract Audit Agency (DCAA), routinely audit and investigate 
government contracts and government contractors’ administrative processes and systems. These agencies review our performance 
on government contracts, pricing practices, cost structure and compliance with applicable laws, regulations and standards. They 
also review our compliance with government regulations and policies and the adequacy of our internal control systems and policies, 
including our purchasing, accounting, estimating, compensation and management information processes and systems. Any costs 
found to be improperly allocated to a specific government contract, unallowable or unreasonable will not be reimbursed, and any 
such costs already reimbursed must be refunded and certain penalties may be imposed. Moreover, if any of the administrative 
processes and systems related to such contracts is found not to comply with governmental requirements, we may be subjected to 
increased government scrutiny that could delay or otherwise adversely affect our ability to compete for or perform government 
contracts or collect our revenue in a timely manner. Therefore, an unfavorable outcome of an audit of our government contracts 
by the DCAA or another government agency could cause our actual results of operations to differ materially and adversely from 
those anticipated.  Each of these outcomes could adversely affect our results of operations.  We do not know the outcome of any 
existing or future audits and if any future audit adjustments significantly exceed our estimates, our profitability could be adversely 
affected.

We rely on the innovation and resources of larger industry participants and public programs in our partnership business to 
advance genomic research and educate physicians/clinicians on genetic diagnostics.

The linkages between genetic anomalies that our products detect and the underlying disease states are not always fully medically 
correlated. Additionally, the availability of correlated genetic markers is dependent on significant investment in genomic research, 
often funded through public programs for which there are no assurances of on-going support. Should any government limit patent 
rights to specific genetic materials, private investment in this area could also be significantly curtailed. In addition, the adoption 
of genetic diagnostics is dependent to a great extent on the education and training of physicians and clinicians. We do not have 
the  resources  to  undertake  such  training,  and  are  relying  on  larger  industry  participants  and  professional  medical  colleges  to 
establish, communicate and educate physicians and clinicians on best practices related to genetic diagnostics.

We are subject to evolving legislative, regulatory, judicial and ethical standards on use of technology and biotechnology.

The adoption of genetic testing is occurring within the broader context of a myriad of decisions related to genetic patenting 
and genotyping. Issues associated with health insurance, data access, intellectual property protection, national and international 
legislative and regulatory initiatives and other variables may have a significant impact on the wide-spread adoption of genetic 
testing or on specific segments or tests within the genetic testing market, which could in turn impact out business.

33

 
Our effective tax rate may fluctuate and we may incur obligations in tax jurisdictions in excess of amounts that have been 
accrued.

We are subject to income taxes in the United States and various foreign jurisdictions.  Our effective tax rate may be lower or 
higher than experienced in the past due to numerous factors, including a change in the mix of our profitability from country to 
country, the establishment or release of valuation allowances against our deferred tax assets, and changes in tax laws.  In addition, 
we have recorded gross unrecognized tax benefits in our financial statements that, if recognized, would impact our effective tax 
rate.  We are subject to tax audits in various jurisdictions, including the United States, and tax authorities may disagree with certain 
positions we have taken and assess additional taxes.  There can be no assurance that we will accurately predict the outcomes of 
these audits, and the actual outcomes could have a material impact on our net income or financial condition. Any of these factors 
could cause us to experience an effective tax rate significantly different from previous periods or our current expectations, which 
could have an adverse effect on our business and results of operations.  The recognition of deferred tax assets is reduced by a 
valuation allowance if it is more likely than not that the tax benefits will not be realized. We regularly review our deferred tax 
assets for recoverability and establish a valuation allowance based on historical income, projected future income, the expected 
timing of the reversals of existing temporary differences and the implementation of tax-planning strategies. 

Changes in tax laws or tax rulings could materially impact our effective tax rate. There are several proposals to reform U.S. 
tax rules being considered by U.S. law makers, including proposals that may reduce or eliminate the deferral of U.S. income tax 
on our unrepatriated earnings, potentially requiring those earnings to be taxed at the U.S. federal income tax rate, reduce or eliminate 
our ability to claim foreign tax credits, and eliminate various tax deductions until foreign earnings are repatriated to the U.S.  Our 
future reported financial results may be adversely affected by tax rule changes which restrict or eliminate our ability to claim 
foreign  tax  credits  or  deduct  expenses  attributable  to  foreign  earnings,  or  otherwise  affect  the  treatment  of  our  unrepatriated 
earnings. 

We hold cash and cash equivalents at various foreign subsidiaries that may not be readily available to meet domestic
cash requirements.

Although we currently hold the substantial majority of our cash and cash equivalents in the United States, we expect our 
various foreign subsidiaries, in particular subsidiaries in Canada, to increase holdings in cash and cash equivalents over time. Any 
cash balances held outside the United States may not be readily available, or may not be available without an additional tax burden, 
to meet our domestic cash requirements. We require a substantial amount of cash in the United States for operating requirements, 
purchases of property and equipment, and for potential future acquisitions. If we are unable to meet our domestic cash requirements 
using domestic cash flows from operations, domestic cash and cash equivalents, by settling loans receivable with our foreign 
subsidiaries, or by domestic borrowing, it may be necessary for us to consider repatriation of earnings that we have designated as 
permanently reinvested. These actions may require us to record additional income tax expense and remit additional taxes, which 
could have a material adverse effect on our results of operations, cash flows and financial condition.

Our stock price has been and is likely to continue to be volatile.

The trading price of our common stock has been and is likely to continue to be highly volatile and subject to wide fluctuations 

in price. This volatility is in response to various factors, many of which are beyond our control, including:

• 

• 

• 

• 

• 

• 

• 

• 

actual or anticipated variations in quarterly operating results from historical results or estimates of results prepared by 
securities analysts;

developments in patents or other intellectual property rights and litigation;

new, or changes in, recommendations, guidelines or studies that could affect the use of our products;

announcements of technological innovations or new products or services by us or our competitors;

announcements by us of significant acquisitions, strategic partnerships, joint ventures or capital commitments;

developments in relationships with our partners, customers and suppliers;

additions or departures of key personnel;

conditions or trends in the life science, biotechnology and pharmaceutical industries, including the regulatory environment;

34

 
• 

• 

• 

• 

• 

• 

• 

published studies and reports relating to the comparative efficacy of products and markets in which we participate;

changes in financial estimates by securities analysts;

general worldwide economic conditions and interest rates;

the success or lack of success of integrating our acquisitions;

instability in the United States and other financial markets and the ongoing and possible escalation of unrest in the Middle 
East, other armed hostilities or further acts or threats of terrorism in the United States or elsewhere;

sales of our common stock; and

the potential adverse impact of the secondary trading of our stock on foreign exchanges which are subject to less regulatory 
oversight than the NASDAQ Global Select Market, without our permission, and the activity of the market makers of our 
stock on such exchanges, including the risk that such market makers may engage in naked short sales and/or other deceptive 
trading practices which may artificially depress or otherwise affect the price of our common stock on the NASDAQ Global 
Select Market.

In addition, the stock market in general, and the NASDAQ Global Select Market and the market for technology companies 
in particular, has experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the 
operating performance of those companies. Further, there has been particular volatility in the market prices of securities of life 
sciences companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless 
of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities 
class action litigation has often been instituted. A securities class action suit against us could result in substantial costs, potential 
liabilities and the diversion of management’s attention and resources.

We may incur impairment charges on our goodwill and intangible assets which would reduce our earnings.

We are subject to Accounting Standards Codification (ASC) 350 “Goodwill and Other” (ASC 350) which requires that goodwill 
and other intangible assets that have an indefinite life be tested at least annually for impairment. Goodwill and other intangible 
assets with indefinite lives must also be tested for impairment between the annual tests if a triggering event occurs that would 
likely reduce the fair value of the asset below its carrying amount.  As of December 31, 2015, goodwill and other intangible assets 
with indefinite lives represented approximately 25% of our total assets.  In the future, if we determine that there has been impairment, 
our financial results for the relevant period would be reduced by the amount of the impairment, net of tax effects, if any. 

Anti-takeover provisions in our certificate of incorporation, bylaws and Delaware law could make a third party acquisition of 
us difficult.

Our certificate of incorporation and bylaws contain provisions that could make it more difficult for a third party to acquire 
us, even if doing so would be beneficial to our stockholders. We are also subject to certain provisions of Delaware law that could 
delay, deter or prevent a change in control of us. These provisions could limit the price that investors might be willing to pay in 
the future for shares of our common stock.

ITEM 3. LEGAL PROCEEDINGS

On August 30, 2012, Abbott Laboratories, Inc. (Abbott) was named as a defendant in a complaint filed by ENZO Life Sciences, 
Inc. (ENZO) in U.S. District Court in Delaware for alleged infringement of U.S. Patent 7,064,197 as a result of Abbott's distribution 
of Luminex's xTAG Respiratory Viral Panel.  Luminex and Abbott entered into an agreement requiring Luminex to defend and 
indemnify Abbott  for  any  alleged  patent  infringement  resulting  from  its  distribution  of  Luminex's  xTAG  Respiratory  Viral 
Panel. The complaint sought unspecified monetary damages and injunctive relief.  Abbott filed an answer to the complaint on 
October 15, 2012.  On November 30, 2012, Luminex intervened in the lawsuit. On January 2, 2013, ENZO filed additional claims 
against Luminex, alleging infringement of U.S. Patent 7,064,197 resulting from Luminex's sale of its xTAG, FlexScript LDA, 
SelecTAG, and xMAP Salmonella Serotyping Assay products and alleging infringement of U.S. Patent 8,097,405 resulting from 
Luminex's sale of MultiCode products.  Luminex filed an answer to ENZO's additional claims on January 28, 2013.  On October 
2, 2013, ENZO filed additional claims against Luminex, alleging infringement of U.S. Patent 6,992,180 resulting from Luminex’s 
sale of MultiCode products.  Luminex filed an answer to ENZO’s additional claims on October 21, 2013. 

Effective July 2, 2015, Luminex agreed to pay ENZO $7.1 million to settle the litigation.  This settlement resulted in the 
entry of orders dismissing (i) with prejudice all claims, counterclaims and causes of action asserted by ENZO against Luminex, 
(ii) without prejudice all claims, counterclaims and causes of action asserted by Luminex against ENZO, (iii) with prejudice all 
claims, counterclaims and causes of action solely under U.S. Patent 7,064,197 asserted in the litigation by ENZO against Abbott 
and (iv) without prejudice all claims, counterclaims and causes of action relating solely to U.S. Patent 7,064,197 asserted by Abbott 
against ENZO; and resulted in the grant to the Company and its affiliates of a fully paid, non-exclusive, worldwide license under 
the patents asserted in the complaint. In addition, the Company and ENZO released each other from certain claims related to the 
above-referenced patents, including the claims and counterclaims asserted in the complaint.  ENZO further released Abbott from 
certain claims, including those asserted in the complaint, related solely to U.S. Patent 7,064,197.  The settlement was entered into 
solely by way of compromise and does not constitute an admission or concession by Luminex of any liability or wrongdoing.

On November 1, 2013, Irori Technologies, Inc. (Irori) filed a complaint against Luminex in U.S. District Court in the 
Southern  District  of  California alleging  infringement  of  its  U.S.  Patents  6,372,428,  6,416,714,  and  6,352,854  resulting  from 
Luminex’s sale of its xMAP and xTAG based products.  Luminex filed a motion to dismiss on January 9, 2014.  Irori filed its 
response to our motion to dismiss on February 7, 2014.  The court granted the motion to dismiss without prejudice on February 
25, 2014.  On March 18, 2014, Irori filed an amended complaint, again alleging infringement of U.S. Patents 6,372,428, 6,416,714, 
and 6,352,854 resulting from Luminex’s sale of its xMAP and xTAG based products.  The complaint sought unspecified monetary 
damages and injunctive relief.  Luminex filed an answer to Irori’s amended complaint on April 2, 2014.  On June 10, 2014, Luminex 
filed with the United States Patent and Trademark Office (USPTO) Patent Trial and Appeal Board a total of five petitions for inter 
partes review (IPR) seeking to invalidate the claims of the three patents involved in the litigation.   On June 17, 2014, Luminex 
filed a motion to stay proceedings in the district court pending the USPTO’s resolution of the IPR of Irori’s patents.  Irori filed its 
opposition to the motion to stay on July 7, 2014, and Luminex filed a reply on July 14, 2014.  On July 16, 2014, the court granted 
Luminex’s motion to stay the case until the earlier of i) a determination by the USPTO that reexamination proceedings will not 
take place or ii) the conclusion of reexamination proceedings and appeals.  On December 11, 2014, the USPTO's Patent Trial and 
Appeal Board instituted review on all five IPR petitions that Luminex filed.  

On March 5, 2015 Luminex and Irori reached a settlement.  The settlement amount was not material.  On March 19, 2015 

the district court dismissed Irori's lawsuit with prejudice.  On March 26, 2015, the IPR petitions were terminated.

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.

As of February 23, 2016, we had 415 holders of record of our common stock. Because many of our shares are held by brokers 
and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial stockholders represented 
by these record holders.

Dividends

We have never declared or paid cash dividends on our common stock and, while this policy is subject to periodic review by 
our board of directors, we currently intend to retain any earnings for use in our business and do not anticipate paying cash dividends 
in the foreseeable future.  Our ability to declare dividends may also from time to time be limited by the terms of any applicable 
credit facility.  Luminex does not currently have a credit facility.

Recent Sales of Unregistered Securities

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS

OF OPERATIONS

The following information should be read in conjunction with the Consolidated Financial Statements and the accompanying 
Notes included below in Item 8 and “Risk Factors” included above in Item 1A of this Annual Report on Form 10-K.  This discussion 
contains forward-looking statements that involve risks and uncertainties.  Our actual results may differ materially from those 
anticipated in these forward-looking statements.

Overview

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

We primarily serve these three industries by marketing products, including our testing equipment and assays, to various types 

of testing laboratories. We have a large installed base of systems that has grown primarily from the following:

• 

placements made by partners who either:

• 

• 

license our xMAP technology and develop products that incorporate our xMAP technology into products that 
they then sell to end users, or 
purchase our proprietary xMAP laboratory instrumentation and our proprietary xMAP microspheres and sell 
xMAP-based assay products and/or xMAP-based testing services, which run on the xMAP instrumentation, and 
pay a royalty to us; and

• 

our direct sales force that focuses on the sale of molecular diagnostic assays that run on our xMAP and ARIES® based 
systems. 

As  of  December 31,  2015,  Luminex  had  73  strategic  partners,  of  which  48  have  released  commercialized  reagent-based 
products utilizing our technology.  Our remaining partners are in various stages of development and commercialization of products 
that incorporate our technology.

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

• 

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, when 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.

•  Assay revenue is generated primarily from three sources: i) the sale of our branded 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, ii) real-time PCR and multiplexed PCR assays using our proprietary MultiCode technology, and  
iii) ARIES® cassettes designed to run a fully automated, sample to answer molecular assay on the ARIES® system. 

• 

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.

42

  
2015 Highlights

•  Consolidated revenue was $237.7 million for 2015, representing a 5% increase over revenue for 2014.

•  Assay revenue of $101.2 million, a 15% increase over 2014.

• 

System shipments of 997 multiplexing analyzers, which included 396 MAGPIX systems, resulting in cumulative life-
to-date multiplexing analyzer shipments of 12,684, up 9% from a year ago. 

•  Royalty revenue reflecting over $480 million of royalty bearing end user sales on our technology for 2015, a 5%

increase in royalty revenue over 2014.

•  Cash and short- and long-term investments at year-end totaled approximately $148 million, an increase of approximately 

$40 million compared with year-end 2014.

•  Received FDA clearance for the ARIES® system,  ARIES® HSV 1&2 Assay and NxTAG® Respiratory Pathogen Panel.

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 partners.  These partners account for more 
than 69% 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.

Segment Information

During the fourth quarter of 2014, following the appointment of our new CEO, Luminex evaluated its historical reporting 
segments: the TSP segment and the ARP segment.  As a result of this evaluation and based upon how our Chief Executive Officer 
as Chief Operating Decision Maker (CODM), and our management team collectively manages our business, we determined that 
the two former segments were so integrated and interrelated that they no longer provided an accurate representation of our business 
when reported separately. Additionally, we also took actions to consolidate sales and service functions.  As a result, effective with 
the  fourth  quarter  of  2014,  we  viewed  and  began  presenting  our  business  as  one  operating  segment  and  one  reporting  unit. 
Accordingly, 2013 information has been restated to conform to the 2014 and 2015 presentation.  

Future Operations

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

• 

• 

• 

• 

• 

• 

placements  of  our ARIES®  system,  the  next  generation  sample  to  answer  platform  for  our  MultiCode-RTx 
technology, including in vitro diagnostic (IVD) assays;

development and commercialization of a pipeline of assays for the ARIES® system;

commercialization of 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;  

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;

43

• 

• 

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

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial 
statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). 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. The 
following is a discussion of our most critical accounting policies used in the preparation of our financial statements, and the 
judgments and estimates involved under each.  We also have other significant accounting policies that do not involve critical 
accounting estimates because they do not generally require us to make estimates and judgments that are difficult or subjective.  These 
are described  in Note  1  of our  Consolidated Financial Statements provided herein  in  Item 8.  Estimates and  assumptions  are 
reviewed periodically. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition.  Revenue is generated primarily from the sale of our products and related services, which are primarily 
support and maintenance services on our systems.  We recognize product revenue at the time the product is shipped provided there 
is persuasive evidence of an agreement, no right of return exists, the fee is fixed or determinable and collectability is probable.  There 
is no customer right of return in our sales agreements.  If the criteria for revenue recognition are not met at the time of shipment, 
the revenue is deferred until all criteria are met.

We regularly enter into arrangements for system sales that are multiple-element arrangements, including services such as 
installation and training, and multiple products.   These products or services are primarily delivered within a short time frame, 
approximately  three  to  six  months,  of  the  agreement  execution  date  and  can  also  be  performed  by  one  of  our  third-party 
partners.  Based on the terms and conditions of the sale, we believe that these services can be accounted for separately from the 
delivered system as our delivered products have value to our customers on a stand-alone basis.  Items are considered to have stand-
alone  value  when  they  are  sold  separately  by  any  vendor  or  when  the  customer  could  resell  the  item  on  a  stand-alone 
basis.   Accordingly, the estimated selling price of services or products not yet performed or delivered at the time of system shipment 
are deferred and recognized as revenue as such services are performed.  We have typically been able to determine the selling price 
of each deliverable in a multiple-element arrangement based on the price for such deliverable when it is sold separately.  If vendor 
specific objective evidence is not determinable and when third-party evidence is not available, we use the estimated selling price 
of a deliverable which is determined based upon our pricing policies, expected margin of the deliverable, geographical location 
and information gathered from customer negotiations.  

Within the diagnostic portion of our business, we provide systems and certain other hardware to customers through reagent 
rental agreements under which the customers commit to purchasing minimum quantities of disposable products at a stated price 
over a defined contract term, which is normally two to three years.  All of these reagent rental agreements are operating leases.  
Instead of rental payments, we recover the cost of providing the system and other hardware in the amount we charge for our 
diagnostic assays and other disposables.  Revenue is recognized over the defined contract term as assays and other disposable 
products are shipped.  The depreciation costs associated with the system and other hardware are charged to cost of sales on a 
straight-line basis over the estimated life of the system.  The costs to maintain these instruments in the field are charged to cost 
of sales as incurred.  

44

Revenue from extended service agreements is deferred and recognized ratably over the term of the agreement.  We may also 
be entitled to milestone payments that are contingent upon our achieving a predefined objective.  We follow the milestone method 
of recognizing revenue from milestones and milestone payments are recorded as revenue in full upon achievement of the milestone.  
Revenues from royalties related to agreements with strategic partners are recognized when such amounts are reported to the 
Company; therefore, the underlying end user sales may be related to prior periods.

Additional revenue is derived from cost-type contracts with the U.S. government. Revenue and profit under cost-plus service 
contracts is recognized as costs are incurred plus negotiated fees. Fixed fees on cost-plus service contracts are recognized ratably 
over  the  contract  performance  period  as  services  are  performed.  Contract  costs  include  labor  and  related  employee  benefits, 
subcontracting costs and other direct costs, as well as allocations of allowable indirect costs. For contract change orders, claims 
or similar items, judgment is required for estimating the amounts, assessing the potential for realization and determining whether 
realization is probable. From time to time, facts develop that require revisions of revenue recognized or cost estimates. To the 
extent that a revised estimate affects the current or an earlier period, the cumulative effect of the revision is recognized in the 
period in which the facts requiring the revision become known. Reimbursements of certain costs, including certain hardware costs 
or out-of-pocket expenses are included in revenue with corresponding costs included in cost of revenue as costs are incurred.

Inventory.  Inventories are valued at the lower of cost or market value, with cost determined according to the standard cost 
method.  Inventories have been written down through an allowance for excess and obsolete inventories. The two major components 
of the allowance for excess and obsolete inventory are (i) a specific write-down for inventory items that we no longer use in the 
manufacture of our products or that no longer meet our specifications and (ii) a write-down against slow moving items for potential 
obsolescence. Inventory is reviewed on a regular basis and adjusted based on management’s review of inventories on hand compared 
to estimated future usage and sales.  While management believes that adequate write-downs for inventory obsolescence have been 
made  in  the  consolidated  financial  statements,  scientific  and  technological  advances  will  continue  and  we  could  experience 
additional inventory write-downs in the future.  However, we do not believe this estimate is subject to significant variability.

Warranties.  We provide for the estimated cost of initial product warranties at the time revenue is recognized. While we engage 
in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service 
delivery costs incurred in correcting a product failure. While management believes that adequate reserve has been made in the 
consolidated financial statements for product warranties, should actual product failure rates, material usage or service delivery 
costs differ from our estimates, revisions to the estimated warranty liability would be required.  However, we do not believe this 
estimate is subject to significant variability.

Purchase Price Allocation, Intangibles and Goodwill. The purchase price allocation for acquisitions requires extensive use 
of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired, 
including in-process research and development, and liabilities assumed based on their respective fair values.   Intangible assets 
with definite lives are amortized over the assets’ estimated useful lives using the straight-line method.   We periodically review 
the estimated useful lives of our identifiable intangible assets, taking into consideration any events or circumstances that might 
result in a diminished fair value or revised useful life.

Goodwill represents the excess of the cost over the fair value of the assets of the acquired business.  We evaluate the carrying 
value of goodwill on a reporting unit level annually, on October 1st of each year, or more frequently if there is evidence that certain 
events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable.  Since 2013, we have 
estimated the fair value of our reporting unit using a “step one” analysis using a fair-value-based approach based on the market 
capitalization or a discounted cash flow (DCF) analysis of our projected future results to determine if it is more likely than not 
that the fair value of a reporting unit is less than its carrying amount.  This analysis requires a comparison of the carrying value 
of the reporting unit to the estimated fair value of the reporting unit.  Determining the fair value of goodwill is subjective in nature 
and often involves the use of estimates and assumptions including, without limitation, use of estimates of future prices and volumes 
for the Company’s products, capital needs, economic trends and other factors which are inherently difficult to forecast.  Our annual 
test, performed on the first day of the fourth quarter, did not result in an impairment charge for 2015 or 2014 as the estimated fair 
value of our reporting unit exceeded the carrying value by a significant enough amount that any reasonably likely change in the 
assumptions used in the analysis would not cause the carrying value to exceed the estimated fair value for the reporting unit as 
determined under our analysis.

45

Accounting for Income Taxes. We calculate our provision for income taxes using the asset and liability method, under which 
deferred tax assets and liabilities are recognized by identifying the temporary differences arising from the different treatment of 
items for tax and accounting purposes. In determining the future tax consequences of events that have been recognized in our 
financial statements or tax returns, judgment is required. Differences between the anticipated and actual outcomes of these future 
tax consequences could have a material impact on our consolidated results of operations or financial position. The recognition of 
deferred tax assets is reduced by a valuation allowance if it is more likely than not that the tax benefits will not be realized. We 
regularly review our deferred tax assets for recoverability and establish a valuation allowance based on historical income, projected 
future income, the expected timing of the reversals of existing temporary differences and the implementation of tax-planning 
strategies.  Undistributed earnings of our foreign subsidiaries are considered permanently reinvested and, accordingly, no provision 
for U.S. federal or state income taxes has been provided thereon.

The GAAP guidance requires recognition of the impact of a tax position in our financial statements only if that position is 
more likely than not to be sustained upon examination by taxing authorities, based on the technical merits of the position. Any 
interest and penalties related to uncertain tax positions will be reflected in income tax expense.   Determining the consolidated 
provision for income taxes involves judgments, estimates and the application of complex tax regulations.  We are required to 
provide for income taxes in each of the jurisdictions where we operate, including estimated liabilities for uncertain tax positions. 
 Although we believe that we have provided adequate liabilities for uncertain tax positions, the actual liability resulting from 
examinations by taxing authorities could differ from the recorded income tax liabilities and could result in additional income tax 
expense having a material impact on our consolidated results of operations.  Changes of estimates in our income tax liabilities are 
reflected in our income tax provision in the period in which the factors resulting in the change to our estimate become known to 
us.  We benefit from the tax credit incentives under the U.S. research and experimentation tax credit extended to taxpayers engaged 
in qualified research and experimental activities while carrying on a trade or business. 

We recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When 
assessing whether excess tax benefits relating to share-based compensation have been realized, we follow the with-and-without 
approach, excluding any indirect effects of the excess tax deductions. Under this approach, excess tax benefits related to share-
based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us.

In March 2010, significant reforms to the healthcare system were adopted as law in the U.S. The law includes provisions that, 
among other things, impose new and/or increased taxes.  Specifically, the law requires manufacturers, producers and importers 
of medical devices to subsidize healthcare reform in the form of a 2.3% excise tax on U.S. sales of certain medical devices as of 
January 1, 2013. Our products which have received FDA approval fall under the government classification and are subject to the 
excise tax.  However, a two-year moratorium on the tax took effect on January 1, 2016 under the Protecting Americans from Tax 
Hikes Act of 2015.

Stock compensation.  All stock-based compensation cost, including grants of stock options, restricted stock units and shares 
issued under the Company’s employee stock purchase plan, is measured at the grant date based on the fair value of the award and 
is recognized as an expense on a straight-line basis over the requisite service period, which is generally the vesting period.  The 
fair value of our stock options is estimated using the Black-Scholes option pricing model. The Black-Scholes valuation calculation 
requires us to estimate key assumptions such as expected volatility, expected term and risk-free rate of return. Calculation of 
expected volatility is based on historical volatility. The expected term is calculated using the contractual term of the options as 
well as an analysis of our historical exercises of stock options.  The estimate of risk-free rate is based on the U.S. Treasury yield 
curve in effect at the time of grant. We have never paid cash dividends and do not currently intend to pay cash dividends, thus we 
have assumed a 0% dividend yield.  

The amount of stock-based compensation expense recognized during a period is based on the value of the portion of the 
awards that are ultimately expected to vest.  As part of the requirements of ASC 718 "Stock Compensation", the Company is 
required to  estimate potential forfeitures of  stock  grants and  adjust compensation  cost recorded  accordingly. The  estimate of 
forfeitures is based on historical forfeiture performance and will be adjusted over the requisite service period to the extent that 
actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through 
a cumulative catch-up adjustment in the period of evaluation and will also impact the amount of stock compensation expense to 
be recognized in future periods. Ultimately, the actual expense recognized over the vesting period will only be for those awards 
that vest, except for the limited number of market based awards under long term incentive plans.  If we use different assumptions 
for estimating stock-based compensation expense in future periods or if actual forfeitures differ materially from our estimated 
forfeitures, the change in our stock-based compensation expense could materially affect our operating income, net income and 
net income per share.

We continue to have revenue concentration in a limited number of customers.  In 2015, the top five customers, by revenue, 
accounted for 54% of total revenue down from 55% of total revenue in 2014.  In particular, our two largest customers by revenue 
accounted for 37% of 2015 total revenue (24% and 13%, respectively) down from 38% of 2014 total revenue (21% and 17%, 
respectively).  No other customer accounted for more than 10% of total revenue in 2015 or 2014.

Revenue from the sale of systems and peripheral components increased 5% to $30.7 million for the year ended December 31, 
2015 from $29.2 million for the year ended December 31, 2014, due to the increase in the total multiplexing analyzer placements.  
We sold 997 multiplexing analyzers in 2015, which included 396 of our MAGPIX systems, as compared to 950 multiplexing 
analyzers sold in 2014, which included 372 MAGPIX systems, bringing total multiplexing analyzer shipments since inception to 
12,684 as of December 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 year ended December 31, 
2015, our five highest selling partners accounted for 769, or 77%, of total multiplexing analyzers sold.  Our five highest selling 
partners accounted for 721, or 76%, of total multiplexing analyzers sold for the year ended December 31, 2014. 

Consumable sales, comprised of microspheres and sheath fluid, decreased to $43.3 million during 2015 from $48.3 million
in 2014. During the year ended December 31, 2015, we had 66 bulk purchases of consumables totaling approximately $31.7 
million (73% of total consumable revenue), ranging from $0.1 million to $4.2 million, as compared with 68 bulk purchases totaling 
approximately $37.6 million (78% of total consumable revenue) in the year ended December 31, 2014.  The decrease in bulk 
purchases in 2015 is the primary driver to the decrease in consumable revenue from the prior year and is primarily the result of 
transient inventory challenges experienced by our largest partner, which is expected to affect consumable sales over the next 
several years.  Partners who reported royalty bearing sales accounted for $30.1 million, or 70%, of consumable sales for the year 
ended December 31, 2015 compared to $38.3 million, or 79%, of the total consumable sales for the year ended December 31, 
2014.

Royalty revenue, which results when our partners sell products or services incorporating our technology, increased 5% to 
$41.5 million for the year ended December 31, 2015 from $39.4 million for the year ended December 31, 2014.  We believe this 
increase is primarily the result of menu expansion and increased utilization of our partners’ assays on our technology. 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 $477.1 million
and $3.6 million, respectively, for the year ended December 31, 2015 as compared to $452.6 million and $3.6 million, respectively, 
for the year ended December 31, 2014. 

Assay revenue increased 15% to $101.2 million for the year ended December 31, 2015 from $87.7 million for the year ended 
December 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 17% from 2014, respectively.  Additionally, 
infectious disease testing and genetic testing assay products represented 67% and 33%, respectively, of total assay revenue in 
2015, consistent with 2014.  Our top customer, by revenue, accounted for 52% of total assay revenue for the year ended December 31, 
2015 compared to 51% for the year ended December 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 may vary, a loss of a significant portion of that revenue is expected by January 
2017.

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, increased 2% to $9.6 million during 2015 from $9.4 million in 
2014.  This increase is attributable to increased penetration of the expanded installed base. At December 31, 2015, we had 1,682 
Luminex systems covered under extended service agreements and $4.2 million in deferred revenue related to those contracts. At 
December 31, 2014, we had 1,522 Luminex systems covered under extended service agreements and $4.1 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, decreased 
to $11.5 million for the year ended December 31, 2015 compared to $13.0 million for the year ended December 31, 2014.  This 
decrease is primarily attributable to a decline of $1.0 million driven by the timing of milestone payments from our development 
agreement with Merck.

Gross Profit. Gross profit increased to $168.7 million for the year ended December 31, 2015, as compared to $159.9 million
for the year ended December 31, 2014. Gross margin (gross profit as a percentage of total revenue) was 71% for the year ended 
December 31, 2015, up from 70% for the year ended December 31, 2014.  Gross margin was higher in 2015 primarily as a result 
of the inclusion in 2014 of $1.2 million of impairment of inventory related to our restructuring plan focused on our Newborn 
Screening Group and our Brisbane, Australia office.  Additionally, concentration of sales in our higher margin items (assays, 
consumables and royalties) was higher than in the prior year, representing 78% of revenue for the year ended December 31, 2015
compared to 77% for the year ended December 31, 2014.  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 $42.7 million, or 18% of total revenue, 
for the year ended December 31, 2015 from $43.1 million, or 19% of total revenue, for the year ended December 31, 2014.  The 
decrease in research and development expense was primarily the result of the savings in materials spending arising from the 
advancement of the ARIES® system through the development phases as well as from the mix of products in the development 
pipeline where the cost of materials required were lower in 2015, partially offset by the higher costs for  clinical trials and expansion 
of assay development capabilities in 2015. The primary focus of our research and development activities is the development and 
commercialization of a pipeline of assays for the ARIES® system. 

Selling, General and Administrative Expense. Selling, general and administrative expenses, excluding the amortization of 
acquired intangible assets, increased to $84.8 million for the year ended December 31, 2015 from $82.8 million for 2014.  The 
increase was attributable to higher personnel costs primarily from incremental headcount related to our direct sales activities, 
increased  incentive  compensation  costs,  and  adverse  foreign  exchange  impacts  in  2015,  which  was  partially  offset  by  lower 
litigation expenditures in 2015.  Selling, general and administrative headcount at December 31, 2015 was 314 as compared to 290 
at December 31, 2014. As a percentage of revenue, selling, general and administrative expense, excluding the amortization of 
acquired intangible assets, was 36% in 2015 compared to 36% in 2014.

Restructuring costs. We recorded total pre-tax restructuring charges of $3.1 million in 2014.  The portion of these charges 
that pertained to the non-cash impairment of inventory and certain of the employee separation costs, $1.2 million, was recorded 
to cost of revenue. The portion of these charges that pertained to the non-cash loss on disposal of our Brisbane, Australia business, 
the non-cash impairment of intangible assets, fixed assets, certain employee separation costs and facility exit costs, $1.9 million, 
was recorded to restructuring costs in our operating expenses. 

Other Income, net. Other income, net increased to $1.0 million for the year ended December 31, 2015 from a loss of $46,000
for the year ended December 31, 2014. The increase was due to the receipt of escrowed funds from the liquidation of our minority 
interest in a private company in 2013, which resulted in a gain of $0.9 million in the first quarter of 2015.

Settlement of litigation. An expense of $7.1 million was recorded in the second quarter of 2015 associated with the settlement 
of litigation with ENZO. The expense associated with the settlement is for partial consideration of a license, dismissal of litigation, 
releases, and covenants granted by ENZO.  In October 2015, Luminex settled a lawsuit that we filed in 2013 against a third party 
alleging breach of contract and patent infringement in exchange for a $2.0 million lump sum payment. We received the $2.0 million 
payment in October 2015 and recorded the settlement as non-operating other revenue in the fourth quarter of 2015.

49

Income taxes. Our effective tax rate for the year ended December 31, 2015 was a benefit of 12%, or $3.8 million, as compared 
to a benefit of 39%, or $11.0 million, for the year ended December 31, 2014. The favorable effective tax rate for 2015 reflects an 
income tax benefit recorded in the fourth quarter resulting from the partial release of the Canadian deferred tax assets valuation 
allowance.  Further release of the Canadian deferred tax assets valuation allowance will be contingent upon future projections of 
profitability of our Canadian subsidiary.  We will record income tax expense on profits generated in our Canadian subsidiary over 
the near term 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.

In 2014, the top five customers, by revenue, accounted for 55% of total revenue up from 54% of total revenue in 2013.  In 
particular, our two largest customers by revenue accounted for 38% of 2014 total revenue (21% and 17%, respectively) up from 
34% of 2013 total revenue (18% and 16%, respectively). No other customer accounted for more than 10% of total revenue in 2014 
or 2013.

Revenue from the sale of systems and peripheral components decreased 8% to $29.2 million for the year ended December 31, 
2014 from $31.8 million for the year ended December 31, 2013, due to the decrease in the total multiplexing analyzer placements. 
 We sold 950 multiplexing analyzers in 2014, which included 372 of our MAGPIX systems, as compared to 1,078 multiplexing 
analyzers sold in 2013, which included 495 MAGPIX systems, bringing total multiplexing analyzer shipments since inception to 
11,687 as of December 31, 2014.  Additionally, system revenue generated in our Brisbane, Australia facility, which was closed in 
2014,  declined by $1.2  million in  2014 from  2013.  For  the year  ended December 31, 2014,  our  five highest  selling partners 
accounted for 721, or 76%, of total multiplexing analyzers sold.  Our five highest selling partners accounted for 895, or 83%, of 
total multiplexing analyzers sold for the year ended December 31, 2013.

Consumable  sales,  comprised  of  microspheres  and  sheath  fluid,  decreased  to $48.3  million during 2014 from $48.5 
million in 2013.   During the year ended December 31, 2014, we had 68 bulk purchases of consumables totaling approximately 
$37.6 million (78% of total consumable revenue), ranging from $0.1 million to $4.8 million, as compared with 74 bulk purchases 
totaling approximately $38.8 million (80% of total consumable revenue), in the year ended December 31, 2013.  The decrease in 
bulk purchases in 2014 was the primary driver to the decrease in consumable revenue from the prior year and was primarily the 
result of transient inventory challenges experienced by our largest partner.  Partners who reported royalty bearing sales accounted 
for $38.3 million, or 79%, of consumable sales for the year ended December 31, 2014 compared to $38.4 million, or 79%, of the 
total consumable sales for the year ended December 31, 2013.

Royalty revenue, which results when our partners sell products or services incorporating our technology, increased 7% to $39.4 
million for the year ended December 31, 2014 from $37.0 million for the year ended December 31, 2013.  We believe this was 
primarily the result of menu expansion and increased utilization of our partners’ assays on our technology. 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 $452.6 million and $3.6 
million, respectively, for the year ended December 31, 2014 as compared to $443.5 million and $2.9 million, respectively, for the 
year ended December 31, 2013

Assay  revenue  increased 18% to $87.7  million for  the  year  ended December 31,  2014 from $74.1  million for  the  year 
ended December 31, 2013. The increase in assay revenue was driven primarily by an increase in both of our primary assay portfolios: 
infectious disease testing and genetic testing assay products which increased 18% and 20% from 2013, respectively.  Additionally, 
infectious disease testing and genetic testing assay products represented 67% and 33%, respectively, of total assay revenue in 2014, 
consistent with 2013. Our top customer, by revenue, accounted for 51% of total assay revenue for the year ended December 31, 
2014 compared to 49% for the year ended December 31, 2013. No other customer accounted for more than 10% of total assay 
revenue during those periods. For the years ended December 31, 2014 and December 31, 2013, direct assay sales comprised 99% 
and 97% of total assay sales, respectively. 

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,  increased 5% to $9.4  million during  2014 from $8.9 
million in 2013.  This increase was attributable to increased penetration of the expanded installed base. At December 31, 2014, 
we had 1,522 Luminex systems covered under extended service agreements and $4.1 million in deferred revenue related to those 
contracts. At December 31, 2013, we had 1,516 Luminex systems covered under extended service agreements and $3.8 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, decreased 
to $13.0 million for the year ended December 31, 2014 compared to $13.1 million for the year ended December 31, 2013.

Gross  Profit. Gross  profit  increased  to $159.9  million for  the  year  ended December 31,  2014,  as  compared  to $143.6 
million for the year ended December 31, 2013. Gross margin (gross profit as a percentage of total revenue) was 70% for the year 
ended December 31, 2014, up from 67% for the year ended December 31, 2013.  Gross margin was higher in 2014 primarily as 
a result of the inclusion in 2013 of $2.6 million of impairment of inventory related to our restructuring plan focused on our Newborn 
Screening  Group  and  our  Brisbane, Australia  office. Additionally,  concentration  of  sales  in  our  higher  margin  items  (assays, 
consumables  and  royalties)  was  higher  than  in  the  prior  year,  representing  77%  of  revenue  for  the  year  ended  December 
31, 2014 compared to 75% for the year ended December 31, 2013. 

Research and Development Expense. Research and development expense decreased to $43.1 million, or 19% of total revenue, 
for the year ended December 31, 2014 from $45.0 million, or 21% of total revenue, for the year ended December 31, 2013. The 
decrease  in  research  and  development  expense  was  primarily  the  result  of  the  savings  in  materials  spending  associated  with 
advancement in the ARIES® system development phases, including transitioning from alpha system builds in 2013 to concluding 
development and preparing for clinical trials in 2014, and the savings realized from our restructuring activities in 2013.

Selling, General and Administrative Expense. Selling, general and administrative expenses, excluding the amortization of 
acquired intangible assets, decreased to $82.8 million for the year ended December 31, 2014 from $87.3 million for 2013.  The 
decrease was primarily attributable to an expense of $7.0 million related to the termination of our molecular diagnostics distribution 
agreements and our full allowance against all accounts receivable balances related to the bankruptcy of a previous customer, 
totaling $3.9 million each, reflected in our 2013 results, partially offset by increased personnel costs due to incremental headcount 
and  increased  incentive  compensation  as  well  as  additional  litigation  expenditures  in  2014.  Selling,  general  and 
administrative headcount at December 31, 2014 was 290 as compared to 281 at December 31, 2013. As a percentage of revenue, 
intangible  assets,  decreased 
selling,  general  and  administrative  expense,  excluding 
to 36% in 2014 compared to 41% in 2013.

Restructuring costs. We recorded total pre-tax restructuring charges of $3.1 million in 2014. The portion of these charges that 
pertained to the non-cash impairment of inventory and certain of the employee separation costs, $1.2 million, was recorded to cost 
of revenue. The portion of these charges that pertained to the non-cash loss on disposal of our Brisbane, Australia business, the 
non-cash impairment of intangible assets, fixed assets, certain employee separation costs and facility exit costs, $1.9 million, was 
recorded to restructuring costs in our operating expenses. We recorded total pre-tax restructuring charges of $5.0 million in 2013. 
The portion of these charges that pertained to the non-cash impairment of inventory and certain of the employee separation costs, 
$2.6 million, was recorded to cost of revenue. The portion of these charges that pertained to the non-cash impairment of intangible 
assets,  fixed  assets  and  certain  employee  separation  costs,  $2.4  million,  was  recorded  to  restructuring  costs  in  our  operating 
expenses. As a result of the organizational change, the Company eliminated approximately 5% of its aggregate workforce.

Other Income, net. Other income, net decreased to a loss of $46,000 for the year ended December 31, 2014 from income 
of $6.7 million for the year ended December 31, 2013. The 2013 amount was due to the liquidation of our minority interest in a 
private company in 2013, which resulted in a gain of $5.4 million and a reduction in the contingent consideration liability established 
in connection with the 2012 acquisition of GenturaDx from $1.4 million to $0 during 2013.

Income taxes. Our effective tax rate for the year ended December 31, 2014 was a benefit of 39%, or $11.0 million, as compared 
to an expense of 38%, or $4.3 million, for the year ended December 31, 2013. The favorable effective tax rate for 2014 reflected 
an income tax benefit recorded in the fourth quarter resulting from the partial release of the Canadian deferred tax assets valuation 
allowance, the recognition of benefits in the Netherlands which were generated by the waiver of intercompany debt and restructuring 
losses related to the Australian entity and the establishment of a tax asset associated with tax paid on intercompany profits.

At December 31, 2015, we held cash, cash equivalents and long-term investments of $148.0 million and had working capital 
of $182.3 million. At December 31, 2014, we held cash, cash equivalents and short-term investments of $107.7 million and had 
working capital of $146.7 million.  Cash, cash equivalents and investments increased by $40.3 million during the year ended 
December 31,  2015.  The  increase  in  cash,  cash  equivalents  and  investments  from  the  prior  year  is  primarily  attributable  to 
significant operating cash flows, coupled with $3.1 million in proceeds from the Company's employee stock purchase plan and 
stock option exercises, partially offset by our capital expenditures of $18.7 million.

We have funded our operations to date primarily through cash generated from operations, the issuance of equity securities (in 
conjunction with an initial public offering in 2000, subsequent option exercises, and our follow-on public offering in 2008).  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.

Cash provided by operations was $55.8 million for the year ended December 31, 2015 as compared with cash provided by 
operations of $49.3 million for the year ended December 31, 2014.  Cash used in investing activities was $22.2 million for the 
year ended December 31, 2015 as compared with $28.5 million for 2014.  The change in cash flows of investing activities from 
2014 to 2015 was primarily attributable to a decrease in the net purchases of our available-for-sale securities of $8.0 million 
partially offset by an increase in capital expenditures of $1.6 million.  Currently, exclusive of changes in available-for-sale securities, 
we  expect  cash  used  in  investing  activities to  be  primarily  for  purchases  of  property  and  equipment,  additional  cost-method 
investments and continued strategic investments or acquisitions.

Cash provided by financing activities decreased to $3.1 million for the year ended December 31, 2015, from $3.4 million for 
the year ended December 31, 2014.  This was primarily attributable to a decrease of $1.6 million in proceeds from sales of common 
stock through the Company's employee stock purchase plan, a decrease in cash from stock option exercises and a decrease of $0.3 
million in excess income tax expense from employee stock-based awards, all of which was partially offset by a $1.6 million 
decrease in the paydowns of indebtedness.

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, the status of competitive products 
and potential costs 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 
2016.  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,  without  limitation:  (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 partners' consumable purchasing patterns; (iv) execution of partnership agreements that include significant up-front license 
fees;  (v) our stock repurchase programs from time to time and (vi) executing strategic investment or acquisition agreements 
requiring significant cash consideration.  

During 2016, we expect a contraction of up to $5 million in consumable sales compared to the prior year as the result of 
transient inventory challenges that our largest bulk purchasing partner is experiencing.  We expect this lower level of purchasing 
to continue over the next several years.  Additionally, certain genetic testing assay revenue from our largest customer is under 
significant pressure from competing technologies and, although timing is uncertain, a loss of a significant portion of that revenue 
is expected by the end of 2016.

53

 
 
 
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 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 significantly or to obtain funds through entering into agreements on unattractive terms. 

Debt

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

Contractual Obligations

As of December 31, 2015, we had approximately $22.2 million in non-cancellable obligations for the next 12 months.  These 
obligations are included in our estimated cash usage during 2016.  The following table reflects our total current non-cancellable 
obligations by period as of December 31, 2015 (in thousands):

(1)  Purchase obligations predominantly relate to contractual arrangements in the form of purchase orders primarily as a 
result of normal inventory purchases or minimum payments due resulting when minimum purchase commitments are 
not met, as well as other operating commitments.

(2)  Amounts represent minimum royalties due on net sales of products incorporating licensed technology and subject to 

a minimum annual royalty payment.

(3)  Due to the uncertainty with respect to the timing of future cash flows associated with Luminex’s unrecognized tax 
benefits at December 31, 2015, Luminex is unable to make reasonably reliable estimates of the timing of cash settlement 
with the respective taxing authority. Therefore, $2.2 million of unrecognized tax benefits have been excluded from the 
contractual obligations table above.  See Note 12 to the Consolidated Financial Statements for a discussion on income 
taxes.  

Inflation

We do not believe that inflation has had a direct adverse effect on our operations to date.  However, a substantial increase in 
product and manufacturing costs and personnel related expenses could have an adverse impact on our results of operations in the 
event these expenses increase at a faster pace than we can increase our system, consumable and royalty revenue rates.

Recently Adopted Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (FASB) issued guidance which simplifies the presentation of 
deferred income taxes. This new guidance requires that deferred tax assets and liabilities be classified as non-current in a statement 
of financial position. We early adopted this guidance effective December 31, 2015 on a prospective basis. Adoption of this guidance 
resulted in a reclassification of our net current deferred tax asset to the net non-current deferred tax asset in our Consolidated 
Balance Sheet as of December 31, 2015. No prior periods were retrospectively adjusted.

Recent Accounting Pronouncements

In July 2015, the FASB issued guidance regarding the measurement of inventory. The new guidance requires inventory to be 
measured at the lower of cost and net realizable value, which is defined as the estimated selling price in the ordinary course of 
business,  less  reasonably predictable costs  of  completion, disposal  and  transportation. This  new  guidance is  effective  for  the 
Company's first quarter of fiscal 2018 and early adoption is permitted. The guidance must be applied prospectively. We are currently 
evaluating the impact of the adoption of this requirement on our consolidated financial statements, but do not anticipate that 
adoption of this guidance will have a material impact on our consolidated financial statements. 

In February 2015, the FASB amended guidance related to consolidation. This guidance focuses on a reporting company’s 
consolidation evaluation to determine whether certain legal entities should be consolidated. This guidance is effective for annual 
periods beginning after December 15, 2015, and is applicable to us in fiscal 2017. Early adoption is permitted, including adoption 
in an interim period. We are currently evaluating this guidance, but do not anticipate that adoption of this guidance will have a 
material impact on our consolidated financial statements. 

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.  In doing so, companies will need to use their judgment and make estimates 
more extensively than under current U.S. GAAP. These judgments may include identifying performance obligations in the contract, 
estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each 
separate performance obligation.  The standard is designed to create greater comparability for financial statement users across 
industries and jurisdictions and also requires enhanced disclosures. On July 9, 2015, the FASB voted in favor of delaying the 
effective date of the new standard by one year, with early adoption permitted as of the original effective date. The guidance is 
effective for fiscal years, and interim periods within those years, beginning after December 15, 2017.  We are currently evaluating 
the impact of the adoption of this standard on our consolidated financial statements.

ITEM 7A.  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 long-term instruments available-for-sale. A 50 basis point fluctuation from average investment returns at 
December 31, 2015 would yield a less than 0.5% 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 and adversely impacted by changes in these and other factors.

55

As of December 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 and Yen. For example, some fixed asset 
purchases and certain expenses 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.  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 and Renminbi exchange rates. A 10% change in all of these exchange rates in relation to the U.S. dollar would 
result in an income statement impact of approximately $641,000 on foreign currency denominated asset and liability balances as 
of December 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  $841,000  was  included  in  determining  our 
consolidated results for the year ended December 31, 2015.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of 
Luminex Corporation

We have audited Luminex Corporation’s internal control over financial reporting as of December 31, 2015, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). Luminex Corporation’s management is responsible for maintaining effective 
internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting 
included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express 
an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control 
over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and  operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in 
the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 In our opinion, Luminex Corporation maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated balance sheets of Luminex Corporation as of December 31, 2015 and 2014, and the related consolidated statements 
of comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2015 
of Luminex Corporation and our report dated February 25, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of
Luminex Corporation

We have audited the accompanying consolidated balance sheets of Luminex Corporation (the Company) as of December 31, 2015 
and 2014, and the related consolidated statements of comprehensive income, shareholders' equity and cash flows for each of the 
three years in the period ended December 31, 2015. These financial statements are the responsibility of the Company's management. 
Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable 
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position 
of Luminex Corporation at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each 
of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles. 

As  discussed  in  Note  18,  effective  December  31,  2015,  the  Company  prospectively  adopted  FASB Accounting  Standards 
Codification Update 15-17 which requires the classification of all deferred tax assets and liabilities as long-term.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Luminex Corporation’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal 
Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013 
framework) and our report dated February 25, 2016 expressed an unqualified opinion thereon.

LUMINEX CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Luminex  Corporation,  the  “Company”  or  “Luminex,”  develops,  manufactures  and  sells  proprietary  biological  testing 
technologies and products with applications throughout the life sciences, pharmaceutical and diagnostics industries.  We have 
established a position in several segments of the life sciences industry by developing and delivering products that meet a variety 
of customer needs in specific market segments, including multiplexing, accuracy, precision, sensitivity, specificity, reduction of 
labor and ability to test for proteins and nucleic acids. These needs are addressed by our proprietary technology, which allows the 
end user in a laboratory to perform biological testing in a multiplexed format. Multiplexing allows for many different laboratory 
results to be generated from one sample with a single assay. 

We have a full range of instruments using our xMAP technology:  our LUMINEX 100/200™ systems offer 100-plex testing;  
our FLEXMAP 3D® system is our high-throughput, 500-plex testing system; and our MAGPIX® system provides 50-plex testing 
at a lower cost using imaging rather than flow cytometry.  By using our xMAP technology, the end users are able to generate 
multiple simultaneous results per sample. Using the products Luminex has available today, up to 500 simultaneous analyte results 
can be determined from a single sample.

We primarily serve the diagnostics, pharmaceutical and life sciences industries by marketing products, including our testing 
equipment and assays, to various types of testing laboratories. We have a large installed base of systems that has grown primarily 
from the following:

• 

placements made by partners who either:

• 

• 

license our xMAP technology and develop products that incorporate our xMAP technology into products that 
they then sell to end users, or 
purchase our proprietary xMAP laboratory instrumentation and our proprietary xMAP microspheres and sell 
xMAP-based assay products and/or xMAP-based testing services, which run on the xMAP instrumentation, and 
pay a royalty to us; and

• 

our direct sales force that focuses on the sale of molecular diagnostic assays that run on our xMAP and ARIES® systems.  

We have recently received FDA clearance for our ARIES® system.  The ARIES® system is a sample to answer clinical test 
system  that  automates  and  integrates  extraction  of  nucleic  acid  from  a  clinical  sample,  performs  real-time  polymerase  chain 
reaction, and detects multiple signals generated by target specific probes. The ARIES® system was commercially launched in the 
fourth quarter of 2015.  We also received FDA clearance for the ARIES® HSV (herpes simplex virus) 1&2 Assay in the fourth 
quarter of 2015.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant 

intercompany transactions and balances have been eliminated upon consolidation.

The Company has reclassified certain 2014 amounts in the accompanying condensed consolidated balance sheet to conform 
to the 2015 presentation. These reclassifications include $0.8 million from accounts receivable, net to prepaids and other.  This 
reclassification was not material to the Company's consolidated financial statements.  

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and 
assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual amounts and results 
could differ from those estimates, and such differences could be material to the financial statements.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash deposits and highly liquid investments with original maturities of three months or 

less when purchased.

64

Investments

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 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.  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 obtaining non-binding 
market prices from the Company's third-party portfolio managers on the last day of the quarter, whose sources may use quoted 
prices in active markets for identical assets or inputs other than quoted prices that are observable either directly or indirectly in 
determining fair value. Declines in fair value below the Company’s carrying value deemed to be other than temporary are charged 
against net earnings.

Fair Value of Financial Instruments

The fair values of financial instruments are determined by obtaining non-binding market prices from the Company's third-
party portfolio managers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets 
or inputs other than quoted prices that are observable either directly or indirectly in determining fair value. The Company’s financial 
instruments include cash and cash equivalents, short-term investments, accounts receivable, cost-method investments, long-term 
investments, accounts payable and accrued liabilities.  The fair values of these financial instruments were not materially different 
from  their  carrying  or  contract  values  at  December 31,  2015  and  2014.    See  Note  6  for  further  details  concerning  fair  value 
measurements.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist of short-term and long-
term  investments  and  trade  receivables. The  Company’s  short-term  investments  consist  of  investments  in  high  credit  quality 
financial institutions, non-government sponsored debt securities and corporate issuers.

The Company provides credit, in the normal course of business, to a number of its customers geographically dispersed primarily 
throughout the U.S. The Company attempts to limit its credit risk by performing ongoing credit evaluations of its customers and 
maintaining adequate allowances for potential credit losses, but the Company does not require collateral.

Laboratory Corporation of America (LabCorp) accounted for 24%, 21% and 18% of our total revenues in 2015, 2014 and 
2013, respectively.  Thermo Fisher Scientific, Inc. accounted for 13%, 17% and 17% of our total revenues in 2015, 2014 and 2013, 
respectively.  Bio-Rad  Laboratories,  Inc.  accounted  for  8%,  7%  and  9%  of  our  total  revenues  in  2015,  2014  and  2013, 
respectively.  No other customer accounted for more than 10% of our total revenues in 2015, 2014 or 2013. 

65

 
 
Inventories

Inventories, consisting primarily of raw materials and purchased components, 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.  As a developer and 
manufacturer of high technology medical equipment, the Company may be exposed to a number of economic and industry factors 
that could result in portions of inventory becoming either obsolete or in excess of anticipated usage. These factors include, but 
are not limited to, technological changes in the Company's markets, ability to meet changing customer requirements, competitive 
pressures on products and prices, and reliability and replacement of and the availability of key components from suppliers. The 
Company's policy is to establish inventory reserves when conditions exist that suggest that inventory may be in excess of anticipated 
demand or is obsolete based upon the Company's assumptions about future demand for products and market conditions. The 
Company regularly evaluates the ability to realize the value of inventory based on a combination of factors including the following: 
historical usage rates, forecasted sales or usage, product expiration or end of life dates, estimated current and future market values 
and new product introductions.  Assumptions used in determining the Company's estimates of future product demand may prove 
to be incorrect, in which case the provision required for excess and obsolete inventory would have to be adjusted. If inventory is 
determined to be overvalued, excess or obsolete, the Company would be required to record impairment charges within cost of 
goods sold at the time of such determination. Although considerable effort is made to ensure the accuracy of forecasts of future 
product demand, any significant unanticipated changes in demand or expected usage could have a significant negative impact on 
the value of inventory and the Company's operating results. When recorded, reserves are intended to reduce the carrying value of 
inventory to its net realizable value. 

Property and Equipment

Property and equipment are carried at cost less accumulated amounts for amortization and depreciation. Property and equipment 
are typically amortized or depreciated on a straight-line basis over the useful lives of the assets, which range from two to seven
years. Leasehold improvements and equipment under capital leases are amortized on a straight-line basis over the shorter of the 
remaining term of the lease or the estimated useful life of the improvements and equipment.  The Company classifies the carrying 
value of Luminex xMAP or ARIES® systems placed within the reagent rental program and the instruments on loan to customers 
in property and equipment as "Assets on loan/rental."

Goodwill and Other Intangible Assets

Goodwill represents the excess of the cost over the fair value of the assets of the acquired business.  In accordance with 
Accounting Standards Codification (ASC) 350 “Goodwill and Other” (ASC 350), goodwill is reviewed for impairment at least 
annually at the beginning of the fourth quarter, or more frequently if impairment indicators arise, using a two-step impairment 
process tested at our sole reporting unit level.  Events or circumstances that could trigger an impairment test include, but are not 
limited to, a significant adverse change in the business climate, significant changes in our use of the acquired assets, significant 
negative industry or economic trends, significant under-performance relative to operating performance indicators and significant 
changes in competition. The Company determined that no triggering events occurred during the year ended December 31, 2015.  
In  2015,  the  Company  estimated  the  fair  value  of  the  reporting  unit  using  a  fair-value-based  approach  based  on  the  market 
capitalization.  In 2014 and 2013, the Company estimated the fair value of the reporting unit using a discounted cash flow (DCF) 
analysis of the Company’s projected future results.  Determining the fair value of goodwill is subjective in nature and often involves 
the use of estimates and assumptions including, without limitation, use of  estimates of future prices and volumes for the Company’s 
products, capital needs, economic trends and other factors which are inherently difficult to forecast.  The Company's annual test 
did not result in an impairment charge in 2015 or 2014, as the estimated fair value of the reporting unit continued to exceed the 
carrying value by a significant enough amount such that any reasonably likely change in the assumptions used in the analysis 
would not cause the carrying value to exceed the estimated fair value for the reporting unit.  No goodwill impairments were 
recorded in 2015, 2014 or 2013.  

Intangible assets are amortized on a straight-line basis over their respective estimated useful lives ranging from 5 to 15 years.   

Any in-process research and development will be an indefinite-lived intangible asset until completion or abandonment, at which 
point it will be accounted for as a finite-lived intangible asset or written off if abandoned.

Impairment of Long-Lived Assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances 
indicate that their net book value may not be recoverable. When such factors and circumstances exist, the Company compares the 
projected undiscounted future cash flows associated with the related asset or group of assets over their estimated useful lives 
against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of 
those assets and is recorded in the period in which the determination was made.

66

Revenue Recognition and Allowance for Doubtful Accounts

Revenue is generated primarily from the sale of the Company’s products and related services, which are primarily support 
and maintenance services on the Company's systems.  The Company recognizes product revenue at the time the product is shipped 
provided there is persuasive evidence of an agreement, no right of return exists, the fee is fixed or determinable and collectability 
is probable.  There is no customer right of return in the Company’s sales agreements.  If the criteria for revenue recognition are 
not met at the time of shipment, the revenue is deferred until all criteria are met.

The Company regularly enters into arrangements for system sales that are multiple-element arrangements, including services 
such as installation and training, and multiple products. These products or services are primarily delivered within a short time 
frame, approximately three to six months, of the agreement execution date and can also be performed by one of the Company’s 
third-party partners.  Based on the terms and conditions of the sale, management believes that these services can be accounted for 
separately from the delivered system as the delivered products have value to customers on a stand-alone basis.  Items are considered 
to have stand-alone value when they are sold separately by any vendor or when the customer could resell the item on a stand-
alone basis.   Accordingly, the estimated selling price of services or products not yet performed or delivered at the time of system 
shipment are deferred and recognized as revenue as such services are performed.  The Company has typically been able to determine 
the selling price of each deliverable in a multiple-element arrangement based on the price for such deliverable when it is sold 
separately.  If vendor specific objective evidence is not determinable and when third-party evidence is not available, management 
uses the estimated selling price of a deliverable, which is determined based upon the Company’s pricing policies, expected margin 
of the deliverable, geographical location and information gathered from customer negotiations.

The Company provides systems and certain other hardware to customers through reagent rental agreements under which the 
customers commit to purchasing minimum quantities of disposable products at a stated price over a defined contract term, which 
is normally two to three years. Instead of rental payments, the Company recovers the cost of providing the system and other 
hardware in the amount charged for diagnostic assays and other disposables. Revenue is recognized over the defined contract term 
as assays and other disposable products are shipped.  The depreciation costs associated with the system and other hardware are 
charged to cost of sales on a straight-line basis over the estimated life of the system. The costs to maintain these instruments in 
the field are charged to cost of sales as incurred.  

Revenue from extended service agreements is deferred and recognized ratably over the term of the agreement.  The Company 
may also be entitled to milestone payments that are contingent upon achieving a predefined objective.  The Company follows the 
milestone method of recognizing revenue from milestones and milestone payments are recorded as revenue in full upon achievement 
of the milestone.  Revenues from royalties related to agreements with strategic partners are recognized when such amounts are 
reported to the Company; therefore, the underlying end user sales may be related to prior periods.

Additional revenue is derived from cost-type contracts with the U.S. government. Revenue and profit under cost-plus service 
contracts are recognized as costs are incurred, plus negotiated fees. Fixed fees on cost-plus service contracts are recognized ratably 
over  the  contract  performance  period  as  services  are  performed.  Contract  costs  include  labor  and  related  employee  benefits, 
subcontracting costs and other direct costs, as well as allocations of allowable indirect costs. For contract change orders, claims 
or similar items, judgment is required for estimating the amounts, assessing the potential for realization, and determining whether 
realization is probable. From time to time, facts develop that require revisions of revenue recognized or cost estimates. To the 
extent that a revised estimate affects the current or an earlier period, the cumulative effect of the revision is recognized in the 
period in which the facts requiring the revision become known. Reimbursements of certain costs, including certain hardware costs 
or out-of-pocket expenses, are included in revenue with corresponding costs included in cost of revenue as costs are incurred.  

The Company continuously monitors collections and payments from its customers and maintains allowances for doubtful 
accounts based upon its historical experience and any specific customer collection issues that have been identified. While such 
credit losses have historically been within the Company’s expectations, there can be no assurance that the Company will continue 
to experience the same level of credit losses that it has in the past. A significant change in the liquidity or financial position of any 
one of the Company’s significant customers, or a deterioration in the economic environment in general, could have a material 
adverse impact on the collectability of the Company’s accounts receivable and its future operating results, including a reduction 
in future revenues and additional allowances for doubtful accounts.

67

Product-Related Expenses

The  Company  provides  for  the  estimated  cost  of  initial  product  warranties  at  the  time  revenue  is  recognized. While  the 
Company engages in product quality programs and processes, the Company’s warranty obligation is affected by product failure 
rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material 
usage  or  service  delivery  costs  differ  from  the  Company’s  estimates,  revisions  to  the  estimated  warranty  liability  would  be 
required.  Shipping and handling costs associated with product sales are included in cost of sales. Advertising costs are charged 
to operations as incurred.  The Company does not have any direct-response advertising.   Advertising expenses, which include 
trade shows and conventions, were approximately $2.3 million, $2.3 million and $2.6 million for 2015, 2014 and 2013, respectively, 
and were included in selling, general and administrative expense in the Consolidated Statements of Comprehensive Income.

Research and Development Costs

Research and development costs are expensed in the period incurred.  Nonrefundable advance payments for research and 
development activities for materials, equipment, facilities and purchased intangible assets that have an alternative future use are 
deferred and capitalized.  The capitalized amounts are expensed as the related goods are delivered or the services are performed.  In 
addition, the Company capitalizes certain internally developed products used for evaluation during development projects that also 
have alternative future uses.  These internally developed assets are generally depreciated on a straight-line basis over the useful 
life of the assets, which range from one to two years.

Foreign Currency Translation

The financial statements of the Company’s foreign subsidiaries are translated in accordance with ASC 830, “Foreign Currency 
Matters.” The reporting currency for the Company is the U.S. dollar. With the exception of its Canadian subsidiary, whose functional 
currency is the U.S. dollar, the functional currency of the Company’s foreign subsidiaries is their local currency. Accordingly, 
assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each balance sheet date. Before translation, 
the Company re-measures foreign currency denominated assets and liabilities, including inter-company accounts receivable and 
payable, into the functional currency of the respective entity, resulting in unrealized gains or losses recorded in selling, general 
and administrative expenses in the Consolidated Statement of Comprehensive Income.  Revenues and expenses are translated 
using  average  exchange  rates  during  the  respective  period.  Foreign  currency  translation  adjustments  are  accumulated  as  a 
component  of  other  comprehensive  income  as  a  separate  component  of  stockholders’  equity.  Gains  and  losses  arising  from 
transactions denominated in foreign currencies are included in selling, general and administrative expenses in the Consolidated 
Statement of Comprehensive Income and to date have not been material.

Incentive Compensation

Management  incentive  plans  are  tied  to  various  financial  and  non-financial  performance  metrics.  Bonus  accruals  made 
throughout the year related to the various incentive plans are based on management’s best estimate of the achievement of the 
specific metrics. Adjustments to the accruals are made on a quarterly basis as forecasts of performance are updated. At year-end, 
the accruals are adjusted to reflect the actual results achieved.

Income Taxes

The Company accounts for income taxes under the asset and liability method.  Deferred tax assets and liabilities are recognized 
for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing 
assets and liabilities and their respective tax bases.  Deferred tax balances are adjusted to reflect tax rates based on currently enacted 
tax laws, which will be in effect in the years in which the temporary differences are expected to reverse.  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.  A 
valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that those 
assets will be realized.

The Company recognizes excess tax benefits associated with share-based compensation to stockholders’ equity only when 
realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, the Company 
follows the with-and-without approach, excluding any indirect effects of the excess tax deductions. Under this approach, excess 
tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits 
available to the Company.

68

 
 
 
The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting 
for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s financial 
statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the 
technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of 
income tax expense.

Settlement of Litigation

Effective July 2, 2015, Luminex agreed to pay $7.1 million to settle a complaint filed by ENZO Life Sciences. See Note 15 
- Commitments and Contingencies. We recorded the settlement as non-operating expense in the second quarter of 2015. In October 
2015, Luminex settled a lawsuit that we filed in 2013 against a third party alleging breach of contract and patent infringement in 
exchange for a $2.0 million lump sum payment.  We received the $2.0 million payment in October 2015 and recorded the settlement 
as non-operating other income in the fourth quarter of 2015.  The Company is not currently a party to any litigation.

Earnings Per Share

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 shares and potential common shares from outstanding stock options, restricted stock units 
(RSUs) and contingently issuable shares resulting from an award subject to performance or market conditions determined by 
applying the treasury stock method. In periods with a net loss, potentially dilutive securities composed of incremental common 
shares issuable upon the exercise of stock options and warrants, and common shares issuable on conversion of preferred stock, 
would be excluded from historical diluted loss per share because of their anti-dilutive effect.

Stock-Based Compensation

The Company accounts for stock-based employee compensation plans under the fair value recognition and measurement 
provisions of ASC 718 “Stock Compensation” (ASC 718).  ASC 718 requires the recognition of compensation expense, using a 
fair-value based method, for costs related to all share-based payments including stock options, restricted stock units and shares 
issued under the Company’s employee stock purchase plan. Pursuant to ASC 718, stock-based compensation cost is measured at 
the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period.

Segment Reporting

During the fourth quarter of 2014, following the appointment of our new CEO, the Company evaluated its historical reporting 
segments: the TSP segment and the ARP segment.  As a result of this evaluation and based upon how the Company's Chief Executive 
Officer and the Company's management team collectively manages its business, management determined that the two former 
segments were so integrated and interrelated that they no longer provide an accurate representation of the Company's business 
when reported separately.  Additionally, management took actions to consolidate sales and service functions.  As a result, effective 
with the fourth quarter of 2014, the Company no longer has two operating segments and, accordingly, the Company's business as 
one operating segment and one reporting unit. 

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.  In 
conjunction with the restructuring plan, 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.  Pretax 
loss related to the Brisbane, Australia facility was $2.8 million and  $3.9 million for the years ended December 31, 2014 and 2013, 
respectively.

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 December 31, 2015 or 2014.

NOTE 4 - ACCOUNTS RECEIVABLE AND RESERVES

The Company records an allowance for doubtful accounts based upon a specific review of all outstanding invoices, known 
collection issues and historical experience. The Company regularly evaluates the collectability of its trade accounts receivables 
and performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and its assessment 
of the customer’s current creditworthiness. These estimates are based on specific facts and circumstances of particular orders, 
analysis  of  credit  memo  data  and  other  known  factors.  Accounts  receivable  consisted  of  the  following  at  December  31  (in

NOTE 6 – FAIR VALUE MEASUREMENT

ASC 820 "Fair Value Measurement" (ASC 820) 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. ASC 820 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 year ended December 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 December 31, 2015 and 2014 (in thousands):

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, as the Company owns less than 20% of the voting 
equity 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 and, as a result, the 
Company's minority interest in that private company was sold.  The Company realized a gain of $5.4 million on this minority 
interest investment in the third quarter of 2013.

75

 
 
The Company regularly evaluates the carrying value of cost-method investments for impairment and whether any events or 
circumstances are identified that would significantly harm the fair value of the investments. 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 Operations.  As the inputs utilized for the Company's periodic impairment 
assessment are not based on observable market data, these cost-method investments are classified within Level 3 of the fair value 
hierarchy.  To determine the fair value of these investments, 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.

Sales of certain of the Company’s systems are subject to a warranty.  System warranties typically extend for a period of twelve 
months from the date of installation or no more than 15 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 Company accounts for income taxes using the liability method in accordance with ASC 740 "Income Taxes" (ASC 740).
Under this method, deferred income taxes are recognized for the future tax consequences of differences between the tax and 
financial accounting bases of assets and liabilities at the end of each reporting period.  Deferred income taxes are based on enacted 
tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. A valuation 
allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized.  As a result of 
prospective application of Accounting Standards Update No. 2015-17, "Income Taxes (Topic 740):  Balance Sheet Classification 
of Deferred Taxes", Luminex offset all deferred tax liabilities and assets, as well as any related valuation allowance, and is presenting 
them as a single non-current amount as of December 31, 2015.  Luminex has not retrospectively adjusted prior periods.  Significant 
components of the Company’s deferred tax assets and liabilities as of December 31 are as follows (in thousands):

Deferred tax assets:

Accrued liabilities and other
Net operating loss and credit carryforwards
Deferred revenue
Depreciation and amortization
Stock compensation and other

Under ASC 740, the Company can only recognize a deferred tax asset to the extent that it is “more likely than not” that these 
assets will be realized.  In evaluating the need for a valuation allowance, all available evidence, both positive and negative, is 
considered to determine whether, based on the weight of that evidence, a valuation allowance is needed.  The Company has 
established a valuation allowance against a portion of its remaining deferred tax assets because it is more likely than not that 
certain deferred tax assets will not be realized.  In determining whether deferred tax assets are realizable, the Company considered 
numerous factors including historical profitability, the amount of future taxable income and the existence of taxable temporary 
differences that can be used to realize deferred tax assets.  The valuation allowance decreased approximately $10.1 million in 
2015 from 2014 primarily due to our Canadian subsidiary which recorded a partial release to valuation allowances on its net 
deferred tax assets.  Based on our recent history of generating income in Canada and our expectation to continue to generate future 
income in Canada in susequent years, we determined that it was more likely than not that a portion of Canadian deferred tax assets 
would be realized.  Luminex recorded a partial release to valuation allowances  on its net deferred tax assets of our Canadian 
subsidiary in 2014.  The potential loss of certain genetic testing assay products revenue from our largest customer for the year 
ended  December  31,  2015  did  not  occur  as  expected  and  this  profitability,  or  potential  reduction  thereof,  was  a  significant 
contributing factor in the determination of whether a portion of the deferred tax assets were realizable in 2015 and 2014.

At December 31, 2015, the Company had gross federal, state and foreign net operating loss carryforwards of approximately 
$71.2 million, $49.2 million, and $11.3 million respectively.  These losses expire beginning in 2016.  Approximately $19.1 million
of the federal net operating loss carryforward is attributable to excess employee stock option deductions, the benefit from which 
will be allocated to additional paid-in capital rather than current earnings if subsequently realized.  Federal and state net operating 
losses of approximately $52.1 million and $49.2 million, respectively, were acquired as part of the acquisitions of U.S. companies. 
These acquired net operating losses are subject to annual limitations due to the "change of ownership" provisions of Section 382 
of the Internal Revenue Code of 1986, as amended, and similar state provisions.  The Company has federal, state and foreign credit 
carryforwards of approximately $11.0 million, $2.4 million, and $12.6 million, respectively.  These credits begin to expire in 2018, 
except for approximately $3.3 million which have an indefinite carryforward period.  Approximately $8.2 million of the federal 
credits are attributable to excess employee stock option deductions, the benefit of which has been allocated to additional paid-in 
capital  rather  than  current  earnings  when  realized.    State  credits  of  approximately  $1.1  million  were  acquired  as  part  of  the 
acquisition of GenturaDx in 2012 and are subject to annual limitations due to the "change of ownership" provisions of Section 
382 of the Internal Revenue Code of 1986, as amended, and similar California state tax provisions.  In addition, the Company has 
a gross scientific research and experimental development pool in Canada of approximately $44.2 million, which has an indefinite 
carryforward period. 

Undistributed earnings of the Company's foreign subsidiaries are considered permanently reinvested and, accordingly, no 
provision for U.S. federal or state income taxes has been provided thereon.  The cumulative amount of undistributed earnings of 
the Company's non-U.S. subsidiaries was approximately $17.2 million at December 31, 2015, $1.4 million at December 31, 2014
and $0.9 million at December 31, 2013.  The increase in undistributed earnings in 2015 is primarily a result of profitability of our 
Canadian subsidiary.  We have not recognized a deferred tax liability on these undistributed earnings because the Company currently 
intends to reinvest these earnings in operations outside the U.S. and determination of such liability, if any, is dependent upon 
circumstances existing if and when remittance occurs.

As  of  December 31,  2015  and  December 31,  2014,  the  Company  had  recorded  gross  unrecognized  tax  benefits  of 
approximately  $2.2  million  and  $2.3  million,  respectively.  All  of  the  unrecognized  tax  benefits  as  of  December 31,  2015,  if 
recognized, would impact the effective tax rate.  The Company recognizes interest expense and penalties associated with uncertain 
tax positions as a component of income tax expense.  During the years ended December 31, 2015 and 2014, the Company recognized 
approximately $47,600 and $31,900 in tax related interest and penalties, respectively.  Reserves for interest and penalties as of 
December 31, 2015 and 2014 are not significant as the Company has net operating loss carryovers.

A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows (in thousands):

Balance at beginning of year

Additions based on tax positions related to the current year
Additions for tax positions of prior years
Reductions for tax positions of prior years
Lapse of statute of limitations

As of December 31, 2015, there were no unrecognized tax benefits that the Company expects would change significantly 

over the next 12 months.

The Company files U.S., state, and foreign income tax returns in jurisdictions with varying statutes of limitations.  In the 
United States and Canada, the statute of limitations with respect to the federal income tax returns for tax years after 2011 are open 
to audit; however, since the Company has net operating losses, the taxing authority has the ability to review tax returns prior to 
the 2011 tax year and make adjustments to these net operating loss carryforwards.  There are numerous other income tax jurisdictions 
for which tax returns are not yet settled, none of which is individually significant.  We are currently under audit in Canada for the 
Company’s scientific research and experimental development pool claims for the 2011 through 2013 tax years.  Although we do 
not expect a material adjustment, the outcome of the audit is not known at this time.  We are not under audit in any other major 
taxing jurisdictions at this time.

NOTE 14 - STOCKHOLDERS' EQUITY, EMPLOYEE BENEFIT PLANS AND STOCK-BASED COMPENSATION

Preferred Stock

The Company’s Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock in one or more series 
and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, 
voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or 
the designation of such series, without further vote or action by the Company’s stockholders.  At December 31, 2015 and 2014, 
there was no preferred stock issued and outstanding.

Stock-Based Compensation

At December 31, 2015, the Company has one stock-based employee compensation plan pursuant to which grants may be 
made: the Third Amended and Restated 2006 Equity Incentive Plan  (Equity Incentive Plan) which was approved at the Company’s 
Annual Meeting on May 25, 2006 and amended at the Company’s Annual Meetings on each of May 21, 2009, May 17, 2012 and 
May 14, 2015.  No further grants shall be made pursuant to the 2000 Long-Term Incentive Plan (2000 Plan), the 2001 Broad-
Based Stock Option Plan (2001 Plan) or the 2006 Management Stock Purchase Plan (MSPP), which was terminated effective 
March 7, 2012.  In addition, at December 31, 2015, the Company has one plan pursuant to which discount purchases may be made 
by the participants in such plan: the Luminex Corporation Employee Stock Purchase Plan (ESPP), which was approved at the 
Company's Annual Meeting on May 17, 2012.

Equity Incentive Plans

Under the Company’s Equity Incentive Plan, certain employees, consultants and non-employee directors have been granted 
RSAs, restricted share units (RSUs) and options to purchase shares of common stock.  The options, RSAs, and RSUs generally 
vest in installments over a three to five year period, and the options expire either five, seven or ten years after the date of grant.  Under 
the Equity Incentive Plan, certain employees of, directors of, and consultants to the Company are eligible to be granted RSAs, 
RSUs, and options to purchase common stock.  The ESPP provides for the granting of rights to certain employees of the Company 
to defer an elected percentage, up to 15%, of their base salary through the purchase of the Company's common stock, discounted 
by 15%.  As of December 31, 2015, there were approximately 5.0 million shares authorized for future issuance under the Company’s 
Equity Incentive Plan and approximately 239,000 shares eligible for purchase pursuant to the terms and conditions of the ESPP 
as more fully described below.

The Equity Incentive Plan and the ESPP are administered by the Compensation Committee of the Board of Directors.  The 
Compensation Committee has the authority to determine the terms and conditions under which awards will be granted from the 
Equity Incentive Plan, including the number of shares, vesting schedule and term, as applicable. Any option award exercise prices, 
as set forth in the Equity Incentive Plan, will be equal to the fair market value on the date of grant.  Under certain circumstances, 
the Company may repurchase previously granted RSAs and RSUs.

On March 7, 2012 and March 19, 2013 the Compensation Committee of the Board adopted the Luminex Corporation 2012 
Long Term Incentive Plan (2012 LTIP) and the 2013 Long Term Incentive Plan (2013 LTIP), respectively.  Awards under all of 
the LTIP plans were granted by the Compensation Committee in the form of RSUs and are to be treated as Performance Awards 
under the Equity Incentive Plan.  Grants of RSUs under the LTIP plans shall initially be unvested and represent the maximum 
amount of shares that participants may receive under the plan, assuming achievement of the maximum level of performance goals 
established for the grant, and subject to adjustment for certain transactions and other extraordinary or non-recurring events that 
may affect Luminex or its financial performance.   

On March 7, 2012, the Company’s former CEO was granted an award for an unvested RSU under the 2012 LTIP for up to 
$2,200,000 worth of shares (grant date fair value) of Luminex common stock, and the Company’s CFO was granted an award for 
an unvested RSU under the 2012 LTIP for up to $550,000 worth of shares (grant date fair value) of Luminex common stock.  The 
actual maximum number of shares of 98,434 shares and 24,608 shares for the former CEO and CFO, respectively, were determined 
on March 7, 2012, based upon the closing price of the stock on that date.  Performance goals under the grants are based on the 
following components, with the following weights given to each: 50% on the trading price of Luminex common stock at the end 
of the performance period and 50% on Luminex’s total income from operations at the end of the performance period.

The 2012 LTIP performance goals are as described below:

• 

• 

Partial or complete achievement of the trading price goal is dependent upon the average closing price of Luminex’s 
common  stock  for  the  twenty  consecutive  trading  days  ending  December 31,  2014,  inclusive,  subject  to  certain 
adjustments as described in the 2012 LTIP. There is a range of trading price targets as follows: a minimum threshold 
of $29.29 per share, a target of $32.54 per share, and a maximum goal of $39.75 per share.  No shares were earned for 
this goal under the 2012 LTIP.

Partial or complete achievement of the total income from operations goal is dependent upon the total income from 
operations for the year ended December 31, 2014, as further described in the 2012 LTIP. Total income from operations 
means Luminex’s income from operations as reflected on the Company’s Consolidated Statement of Comprehensive 
Operations for the year ended December 31, 2014, as further described in the 2012 LTIP. There is a range of targets 
as follows: a minimum threshold of $58,663,000, a target of $67,286,000, and a maximum goal of $85,831,000.  No 
shares were earned for this goal under the 2012 LTIP.

81

 
On March 19, 2013, the Company’s former CEO was granted an award for an unvested RSU under the 2013 LTIP for up to 
$1,200,000 worth of shares (grant date fair value) of Luminex common stock, and the Company’s CFO was granted an award for 
an unvested RSU under the 2013 LTIP for up to $300,000 worth of shares (grant date fair value) of Luminex common stock.  The 
actual maximum number of shares of 71,727 shares and 17,931 shares for the former CEO and CFO, respectively, were determined 
on March 19, 2013, based upon the closing price of the stock on that date.  The performance goal under the grants is based on 
Luminex’s  fully  diluted  earnings  per  share  at  the  end  of  the  performance  period  (Adjusted  EPS  Goal).    Partial  or  complete 
achievement of the Adjusted EPS Goal is dependent upon Luminex's fully diluted earnings per share for the year ended December 
31, 2015, as further described in the 2013 LTIP.  There is a range of targets as follows: a minimum threshold of $1.06 per share, 
a target of $1.18 per share, and a maximum goal of $1.36 per share.  The final determination and certification of the shares earned 
for this goal will be made by the Compensation Committee of the Board of Directors after the filing of this Annual Report on 
Form 10-K, but we expect no shares will be earned for this goal under the 2013 LTIP.

In the event that a participant achieves less than the maximum level of the performance goal, the total number of shares 
represented by such RSU shall be reduced to reflect where actual performance lies in the range of performance goals and weighted 
aggregate corresponding payout opportunities established for the grant. Calculation of shares between threshold and maximum 
performance shall be determined based on straight-line interpolation.

Accounting for Stock Compensation

Stock-based compensation costs are generally based on the fair value calculated from the Black-Scholes option-pricing model 
on the date of grant for stock options and market value on the date of grant for RSAs.  The fair values of stock and stock options 
are amortized as compensation expense on a straight-line basis over the vesting period of the grants.

In accordance with ASC 718, the Company evaluates the assumptions used in the Black-Scholes model at each grant date 
using a consistent methodology for computing expected volatility, expected term and risk-free rate of return. Calculation of expected 
volatility is based on historical volatility. The expected life is calculated using the contractual term of the options as well as an 
analysis of the Company’s historical exercises of stock options.  The estimate of the risk-free rate is based on the U.S. Treasury 
yield curve in effect at the time of grant. The Company has never paid cash dividends and does not currently intend to pay cash 
dividends, and thus has assumed a 0% dividend yield.  The assumptions used are summarized in the following table:

Dividend yield
Expected volatility
Risk-free rate of return
Expected life of a 10 year contractual term option
Expected life of a 7 year contractual term option

As part of the requirements of ASC 718, the Company is required to estimate potential forfeitures of stock grants and adjust 
compensation cost recorded accordingly. The estimate of forfeitures is based on historical forfeiture performance and will be 
adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. 
Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of evaluation and will 
also impact the amount of stock compensation expense to be recognized in future periods.

As of December 31, 2015, there was $18.5 million of unrecognized compensation cost related to RSAs and RSUs.  That cost 
is expected to be recognized over a weighted average-period of 2.2 years.  The total fair value of restricted shares vested during 
the year ended December 31, 2015, 2014 and 2013 was $8.5 million, $6.5 million, and $7.2 million, respectively.

RSAs and RSUs may be granted at the discretion of the Board of Directors under the Equity Incentive Plan in connection 
with the hiring or retention of key employees and are subject to certain conditions. Restrictions expire at certain dates after the 
grant date in accordance with specific provisions in the applicable agreement. During the year ended December 31, 2015, the 
Company awarded 276,271 shares of RSAs, which had a fair value at the date of grant ranging from $15.93–$16.72. During the 
year ended December 31, 2014, the Company awarded 637,184 shares of RSAs, which had a fair value at the date of grant ranging 
from $16.82–$21.10. During the year ended December 31, 2013, the Company awarded 353,537 shares of RSAs, which had a 
fair value at the date of grant ranging from $16.18–$18.11.  During the year ended December 31, 2015, the Company awarded 
121,802  shares  of  RSUs,  which  had  a  fair  value  at  the  date  of  grant  ranging  from  $15.93–$16.72.  During  the  year  ended 
December 31, 2014, the Company awarded 139,417 shares of RSUs, which had a fair value at the date of grant ranging from 
$17.91–$20.14.  During the year ended December 31, 2013, the Company awarded 199,051 shares of RSUs, which had a fair 
value at the date of grant ranging from $16.73–$20.51. Compensation under these RSAs and RSUs was charged to expense over 
the restriction period and amounted to $8.1 million, $8.1 million, and $7.5 million in 2015, 2014 and 2013, respectively.  There 
were no significant stock compensation costs capitalized into assets as of December 31, 2015, 2014 or 2013.

The Company received $1.9 million, $3.7 million, and $7.6 million for the exercise of stock options during the years ended 
December 31, 2015, 2014 and 2013, respectively.  Cash was not used to settle any equity instruments previously granted. The 
Company issued shares pursuant to grants relating to each of the Equity Incentive Plan and 2000 Plan from reserves upon the 
exercise of stock options and vesting of RSAs.

Employee Savings Plans and Other Benefit Plans

Effective January 1, 2001, the Company began sponsoring a retirement plan authorized by section 401(k) of the Internal 
Revenue Code for the Company’s employees in the United States. In accordance with the 401(k) plan, all employees are eligible 
to participate in the plan on the first day of the month following the commencement of full time employment. For 2015, 2014 and 
2013, each employee could contribute a percentage of compensation up to a maximum of $18,000, $17,500, and $17,500 per year, 
respectively, with the Company matching 50% of each employee’s contributions.  Effective January 1, 2010, the Company began 
contributing to a deferred profit sharing plan for its Canadian employees.  All Canadian employees are eligible to participate in 
the plan.  The Company’s contributions to these plans for 2015, 2014 and 2013 were $2.8 million, $2.5 million, and $2.4 million, 
respectively.

Several of the Company’s Netherlands employees are covered by a defined benefit plan.  The cost and total liability to the 
Company is not material.  Effective January 1, 2011, all of the Company’s new hires in the Netherlands are eligible to participate 
in a defined contribution plan.

Employee Stock Purchase Plan 

In May 2012, the Company's stockholders approved the ESPP, which provides for the granting of up to 500,000 shares of the 
Company's  common  stock  to  eligible  employees.    The  ESPP  period  is  semi-annual  and  allows  participants  to  purchase  the 
Company's common stock at 85% of the lesser of (i) the closing market value per share of the common stock on the first trading 
date of the option period or (ii) the closing market value per share of the common stock on the last trading date of the option 
period. The first plan option period began on July 1, 2012.  As of December 31, 2015, 2014 and 2013, 260,536 shares, 181,401
shares and 106,522 shares, respectively had been issued out of the ESPP.  The related stock-based compensation expense was $0.4 
million, $0.4 million and $0.4 million for 2015, 2014 and 2013, respectively. 

The Company uses the Black-Scholes model to estimate the fair value of shares to be issued under the ESPP as of the grant 

date using the following weighted average assumptions:

These non-cancellable lease commitments related to facilities include certain rent escalation provisions which have been 
included in the minimum annual rental commitments shown above.  These amounts are recorded to expense on a straight-line 
basis over the life of the lease.  In addition, some of the Company’s leases contain options to renew the lease for five to ten years 
at  the  then  prevailing  market  rental  rate,  right  of  first  refusal  to  lease  additional  space  that  becomes  available,  or  leasehold 
improvement incentives.

Non-Cancellable Purchase Commitments

As of December 31, 2015 the Company had approximately $21.0 million in purchase commitments primarily with several 
of its inventory suppliers as well as other operating commitments. Certain of our supply agreements require purchase and delivery 
of minimum amounts of components through 2018, and purchases under these arrangements were $1.2 million, $2.4 million and 
$1.8 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Employment Contracts

The Company has entered into employment contracts with certain of its key executives.  Generally, certain amounts may 
become payable in the event the Company terminates the executives’ employment without cause or the executive resigns for good 
reason.

Legal Proceedings

On August 30, 2012, Abbott Laboratories, Inc. (Abbott) was named as a defendant in a complaint filed by ENZO Life Sciences, 
Inc. (ENZO) in U.S. District Court in Delaware for alleged infringement of U.S. Patent 7,064,197 as a result of Abbott's distribution 
of Luminex's xTAG Respiratory Viral Panel.  Luminex and Abbott entered into an agreement requiring Luminex to defend and 
indemnify Abbott  for  any  alleged  patent  infringement  resulting  from  its  distribution  of  Luminex's  xTAG  Respiratory  Viral 
Panel. The complaint sought unspecified monetary damages and injunctive relief.  Abbott filed an answer to the complaint on 
October 15, 2012.  On November 30, 2012, Luminex intervened in the lawsuit. On January 2, 2013, ENZO filed additional claims 
against Luminex, alleging infringement of U.S. Patent 7,064,197 resulting from Luminex's sale of its xTAG, FlexScript LDA, 
SelecTAG, and xMAP Salmonella Serotyping Assay products and alleging infringement of U.S. Patent 8,097,405 resulting from 
Luminex's sale of MultiCode products.  Luminex filed an answer to ENZO's additional claims on January 28, 2013.  On October 
2, 2013, ENZO filed additional claims against Luminex, alleging infringement of U.S. Patent 6,992,180 resulting from Luminex’s 
sale of MultiCode products.  Luminex filed an answer to ENZO’s additional claims on October 21, 2013.  

Effective July 2, 2015, Luminex agreed to pay ENZO $7.1 million to settle the litigation.  This settlement resulted in the entry 
of orders dismissing (i) with prejudice all claims, counterclaims and causes of action asserted by ENZO against Luminex, (ii) 
without prejudice all claims, counterclaims and causes of action asserted by Luminex against ENZO, (iii) with prejudice all claims, 
counterclaims and causes of action solely under U.S. Patent 7,064,197 asserted in the litigation by ENZO against Abbott and (iv) 
without prejudice all claims, counterclaims and causes of action relating solely to U.S. Patent 7,064,197 asserted by Abbott against 
ENZO; and resulted in the grant to the Company and its affiliates of a fully paid, non-exclusive, worldwide license under the 
patents asserted in the complaint.  In addition, the Company and ENZO released each other from certain claims related to the 
above-referenced patents, including the claims and counterclaims asserted in the complaint.  ENZO further released Abbott from 
certain claims, including those asserted in the complaint, related solely to U.S. Patent 7,064,197.  The settlement was entered into 
solely by way of compromise and does not constitute an admission or concession by Luminex of any liability or wrongdoing.

86

Because Luminex (i) has never paid any royalties to ENZO in the past, (ii) will not be required to pay any future or ongoing 
royalties to ENZO as a result of the settlement, (iii) has never recorded any revenue or expense related to ENZO in operating 
revenue or in operating expenses in the past, outside of legal fees, and (iv) believes that it does not infringe on any valid and 
enforceable claim with respect to the asserted patents, Luminex determined that this settlement of litigation expense was outside 
of operations.  Luminex accordingly recorded the settlement as a separate, non-operating line item in the second quarter of 2015.  
Luminex made the $7.1 million payment to ENZO in July 2015.

On November 1, 2013, Irori Technologies, Inc. (Irori) filed a complaint against Luminex in U.S. District Court in the Southern 
District of California alleging infringement of its U.S. Patents 6,372,428, 6,416,714, and 6,352,854 resulting from Luminex’s sale 
of its xMAP and xTAG based products. Luminex filed a motion to dismiss on January 9, 2014. Irori filed its response to our motion 
to dismiss on February 7, 2014. The court granted the motion to dismiss without prejudice on February 25, 2014. On March 18, 
2014, Irori filed an amended complaint, again alleging infringement of U.S. Patents 6,372,428, 6,416,714, and 6,352,854 resulting 
from Luminex’s sale of its xMAP and xTAG based products. The complaint sought unspecified monetary damages and injunctive 
relief. Luminex filed an answer to Irori’s amended complaint on April 2, 2014. On June 10, 2014, Luminex filed with the USPTO’s 
Patent Trial and Appeal Board a total of five petitions for inter partes review (IPR) seeking to invalidate the claims of the three 
patents involved in the litigation. On June 17, 2014, Luminex filed a motion to stay proceedings in the district court pending the 
USPTO’s resolution of the IPR of Irori’s patents. Irori filed its opposition to the motion to stay on July 7, 2014, and Luminex filed 
a reply on July 14, 2014. On July 16, 2014, the court granted Luminex’s motion to stay the case until the earlier of i) a determination 
by the USPTO that reexamination proceedings will not take place or ii) the conclusion of reexamination proceedings and appeals. 
On December 11, 2014, the USPTO's Patent Trial and Appeal Board instituted review on all five IPR petitions that Luminex filed.

On March 5, 2015 Luminex and Irori reached a settlement. The settlement amount was not material. On March 19, 2015 the 

district court dismissed Irori's lawsuit with prejudice. On March 26, 2015, the IPR petitions were terminated.

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. 

Other Matters

In January 2013, the Company finalized the termination of its molecular diagnostics distribution agreements and an expense 
of $7.0 million was recorded in selling, general and administrative expenses in the first quarter of 2013.  All payments were made 
in the second quarter of 2013.

NOTE 16 - GUARANTEES

The terms and conditions of the Company’s development and supply and license agreements with its strategic partners generally 
provide for a limited indemnification of such partners, arising from the sale of Luminex systems and consumables, against losses, 
expenses and liabilities resulting from third-party claims based on an alleged infringement on an intellectual property right of such 
third party. The terms of such indemnification provisions generally limit the scope of and remedies for such indemnification 
obligations to a multiple of amounts paid by such strategic partner to Luminex during the previous annual period(s). To date, the 
Company has not had to reimburse any of its strategic partners for any losses arising from such indemnification obligations.

The Company's aggregate foreign currency transaction losses of $841,000, $16,000 and $385,000 were included in determining 

the consolidated results for the years ended December 31, 2015, 2014 and 2013, respectively.

NOTE 18 - RECENT ACCOUNTING PRONOUNCEMENTS

In November 2015, the FASB issued guidance which simplifies the presentation of deferred income taxes. This new guidance 
requires that deferred tax assets and liabilities be classified as non-current in a statement of financial position. The Company early 
adopted this guidance effective December 31, 2015 on a prospective basis. Adoption of this guidance resulted in a reclassification 
of the Company's net current deferred tax asset to the net non-current deferred tax asset in the Company's Consolidated Balance 
Sheet as of December 31, 2015. No prior periods were retrospectively adjusted.

In July 2015, the FASB issued guidance regarding the measurement of inventory. The new guidance requires inventory to be 
measured at the lower of cost and net realizable value, which is defined as the estimated selling price in the ordinary course of 
business,  less  reasonably predictable costs  of  completion, disposal  and  transportation. This  new  guidance is  effective  for  the 
Company's first quarter of fiscal 2018 and early adoption is permitted. The guidance must be applied prospectively. The Company 
is currently evaluating the impact of the adoption of this requirement on its consolidated financial statements, but does not anticipate 
that adoption of this guidance will have a material impact on its consolidated financial statements. 

In February 2015, the FASB amended guidance related to consolidation. This guidance focuses on a reporting company’s 
consolidation evaluation to determine whether certain legal entities should be consolidated. This guidance is effective for annual 
periods beginning after December 15, 2015, and is applicable to the Company in fiscal 2017. Early adoption is permitted, including 
adoption in an interim period. The Company is currently evaluating this guidance, but does not anticipate that adoption of this 
guidance will have a material impact on its consolidated financial statements. 

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.  In doing so, companies will need to use their judgment and make estimates 
more extensively than under current U.S. GAAP. These judgments may include identifying performance obligations in the contract, 
estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each 
separate performance obligation.  The standard is designed to create greater comparability for financial statement users across 
industries and jurisdictions and also requires enhanced disclosures. On July 9, 2015, the FASB voted in favor of delaying the 
effective date of the new standard by one year, with early adoption permitted as of the original effective date. The guidance is 
effective for fiscal years, and interim periods within those years, beginning after December 15, 2017.  The Company is currently 
evaluating the impact of the adoption of this standard on its consolidated financial statements.

ITEM 9A. 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 (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 
Securities  and  Exchange  Commission’s  rules  and  forms  and  that  such  information  is  accumulated  and  communicated  to  the 
Company’s management, including the Company’s 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 
the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness 
of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this 
report.  Based on the evaluation and criteria of these disclosure controls and procedures, the Chief Executive Officer and Chief 
Financial Officer concluded that the Company’s disclosure controls and procedures were effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such 
term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, 
including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal 
control over financial reporting as of December 31, 2015 based on the 2013 framework in Internal Control—Integrated Framework 
issued  by  the  Committee  of  Sponsoring  Organizations  of  the Treadway  Commission  (COSO).  Based  on  that  evaluation,  our 
management concluded that our internal control over financial reporting was effective as of December 31, 2015. Because of its 
inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Projections of any evaluation 
of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, 
or that the degree of compliance with the policies or procedures may deteriorate.

Our  independent  registered  public  accounting  firm,  Ernst  & Young  LLP,  has  issued  a  report  on  their  assessment  of  the 
effectiveness of our internal control over financial reporting, which is provided at Item 8 "Financial Statements and Supplementary 
Data," page 58.

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  fourth  quarter  of  2015  that  have  materially  affected,  or  are  reasonably  likely  to 
materially affect, our internal control over financial reporting.
