PART I

ITEM 1.
ITEM 1.Business
Overview
We are a leading developer, manufacturer, and marketer of life science tools and integrated systems for the analysis of genetic variation and biological function. We were incorporated in California in April 1998 and reincorporated in Delaware in July 2000. Our principal executive offices are located at 9885 Towne Centre Drive,5200 Illumina Way, San Diego, California 92121.92122. Our telephone number is(858) 202-4500.

Using our proprietary technologies, we provide a comprehensive line of genetic analysis solutions, with products and services that currently serve thea broad range of highly interconnected markets, including sequencing, genotyping, and gene expression markets, and we expect to enter the market for molecular diagnostics.expression. Our customers include leading genomic research centers, pharmaceutical companies, academic institutions, government laboratories, and clinical research organizations, as well as pharmaceutical, biotechnology, agrigenomics, and biotechnology companies.consumer genomics companies, and in vitro fertilization clinics.

We developOur broad portfolio of systems, consumables, and commercializeanalysis tools are designed to simplify genetic analysis. This portfolio addresses a range of genomic complexity, price points, and throughputs, enabling researchers to select the best solution for their scientific challenge. Our leading edge sequencing technologiesinstruments can be used to efficiently perform a range of nucleic acid (DNA, RNA) analyses including de novo sequencing, whole genome re-sequencing, gene expression analysis, and small RNA analysis. Our product and service offerings also include leading-edgeon large numbers of samples. For more focused studies, our array-based solutions forprovide ideal tools to perform genome-wide association studies (GWAS) involving single-nucleotide polymorphism (SNP) genotyping and copy number variation (CNV), DNA methylation studies,analyses, as well as gene expression profiling, and low-multiplex analysis ofother DNA, RNA, and protein. Weprotein studies.

In 2012 and early 2013, we took significant steps to support our goal of becoming the leader in genomic-based diagnostics by acquiring BlueGnome Ltd. (BlueGnome) in September 2012 and signing a definitive agreement to acquire Verinata Health, Inc. (Verinata) in January 2013. Our acquisition of BlueGnome, a leading provider of solutions for the screening of genetic abnormalities associated with developmental delay, cancer, and infertility, enhances our ability to establish integrated solutions in reproductive health and cancer. Upon completion of the Verinata acquisition, our focus on reproductive health will be further strengthened by having access to Verinata’s verifi® prenatal test, the broadest non-invasive prenatal test (NIPT) available today for high-risk pregnancies, and what we believe to be the most comprehensive intellectual property portfolio in the NIPT industry. To further enhance our genetic analysis workflows, in 2011 we are the only company with genome-scale technologyacquired Epicentre Technologies Corporation, a leading provider of nucleic acid sample preparation reagents and specialty enzymes for sequencing genotyping, and gene expression —microarray applications. In 2010, through our acquisition of Helixis, Inc. (Helixis), we expanded our portfolio to include real-time polymerase chain reaction (PCR), one of the three cornerstones of modern genetic analysis.most widely used technologies in life sciences. Our Eco Real-Time PCR System provides researchers with an affordable, full-featured system to perform targeted validation studies.

Our tools provide researchers around the world with the performance, throughput, cost effectiveness, and flexibility necessary to determine and analyze the billions of bits of genetic information needed to extract valuable medical information from advances in genomics and proteomics. We believe this information will enable researchers to correlate genetic variation and biological function, which will enhance drug discovery and clinical research, allow diseases to be detected earlier, and permit better choices of drugs for individual patients.
In 2007 we acquired Solexa, Inc. As a result of that transaction, we acquired the sequencing technology utilized in our HiSeq 2000 and Genome Analyzer instrument platforms. These products perform DNA sequencing based on a proprietary reversible terminatorsequencing-by-synthesis (SBS) chemistry.
During the first quarter of 2008, we reorganized our operating structure into two newly-created business segments, the Life Sciences Business Unit and the Diagnostics Business Unit. During 2009, the Diagnostics Business Unit had limited business activity and, accordingly, operating results are reported on an aggregate basis as one operating segment. In the future, at each reporting period end, we will reassess our reportable operating segments, particularly as we enter the market for molecular diagnostics.
Industry Background

DNA, RNA, and ProteinGenetics Primer

The genetic content that controls an organism’sinstruction set for all living cells is encoded in deoxyribonucleic acid, or DNA. The human body, for instance, is composed of billions of cells, each containing DNA, which encodeswith the basic instructions for cellular function. The complete set of an organism’s DNA is calledfor any organism referred to as its genome. The human genome is organized into 23 pairs of chromosomes that are further divided into over 30,000 smallerDNA contains small regions called genes. Each gene is comprised ofgenes, which comprise a string of nucleotide bases labeled A, C, G, and T, representing adenine, cytosine, guanine, and thymine, respectively. Human DNA has approximately 3 billionThese nucleotide bases and theirare present in a precise order is known as the DNA sequence. When a gene is “expressed,” a partial copy of its DNA sequence - called messenger RNA or mRNA —(mRNA) - is used as a template to direct the synthesis of a particular protein. Proteins, in turn, direct all cellular function. The illustration below is a simplified gene expression schematic.

Table of ContentsGenetic Variation and Biological Function


Every person inherits two copies of each gene — one from each parent. The two copies of each gene may be identical, or they may be different. These differencesVariations among organisms are referreddue, in large part, to as genetic variation. Examples of the physical consequences of genetic variation include differences in eye and hair color. Genetic variationtheir DNA sequences. Changes caused by insertions, deletions, inversions, or duplications of nucleotide bases may result in certain genes becoming over-expressed (excessive protein production), under-expressed (reduced protein production), or silenced altogether, sometimes triggering changes in cellular function. These changes can also have important medical consequences. Genetic variation affects disease susceptibility, including predisposition to cancer, diabetes, cardiovascular disease, and Alzheimer’s disease. In addition, genetic variation may cause people to respond differently tobe the same drug treatment. Some people may respond well, others may not respondresult of heredity, but most often they occur at all, and still others may experience adverse side effects. Arandom. The most common form of genetic variation in humans is called a SNP. A SNPsingle nucleotide polymorphism (SNP), which is a variation in a single position of a nucleotide base in a DNA sequence. It is estimated that the human genome contains over 30 million SNPs.
While in some cases a single SNP will be responsible for medically important effects, it is now believed that combinations of SNPs may contribute to the development of most common diseases. SinceCopy number variations (CNVs) occur when there are millionsfewer or more copies of SNPs, it is importantcertain genes, segments of a gene, or stretches of DNA.

In humans, genetic variation accounts for many of the physical differences we see (e.g., height, hair, eye color, etc.). More importantly, these genetic variations can have medical consequences affecting disease susceptibility, including predisposition to investigate many representative, well-chosen SNPs simultaneously in ordercomplex genetic diseases such as cancer, diabetes, cardiovascular disease, and Alzheimer’s disease. They can also impact an individual’s response to discover medically valuable information.certain drug treatments, causing them to respond well, not respond at all, or experience adverse side effects - an area of study known as pharmacogenomics.

Another contributor to disease is the over- or under-expression of genes within an organism’s cells. A very complex network of genes interacts to maintain health in complex organisms. The challenge for scientists is to delineate the associated genes’ expression patternsScientists are studying these variations and their relationshipconsequences in humans, as well as a broad range of animals, plants, and microorganisms. Researchers investigating human, viral, and bacterial genetic variation are helping us to disease. Historically, this problem was addressed by investigating effects on agene-by-gene basis. Thisbetter understand the mechanisms of disease, and thereby develop more effective therapeutics and diagnostics. Greater insight into genetic variation in plants (e.g., food and biofuel crops) and animals (e.g., livestock and domestic animals) is time consuming,enabling scientists to improve crop yields and difficulties exist when several pathways cannot be observed or “controlled” at the same time. With the advent of microarray technology, thousands of genes can now be tested at the same time.animal breeding programs.

There are multipleThe methods offor studying genetic variation and biological function includinginclude sequencing, SNP genotyping, andCNV analysis, gene expression profiling, and gene regulation and epigenetic analysis, each of which is uniquely addressed inby our breadth of products and services.

Life Sciences Research Primer

Life science research encompasses the study of current productsall living things, from humans, animals, and services supports a rangeplants, to viruses and bacteria. It is being performed in government, university, pharmaceutical, biotechnology, and agrigenomics laboratories around the world, where scientists are seeking to expand our knowledge of applications, from highest multiplexing (for whole-genome discovery and profiling) to mid-and low-multiplexing options (for high-throughput targeted screening). Furthermore, our products and services support both the upstream discovery process and the downstream test development process in order to understand genetic variationbiological functions essential for life. Beginning at the DNA, RNA,genetic level, where our tools are used to elucidate the correlation between gene sequence and protein levels.
Sequencing
DNA sequencing isbiological processes, life science research expands to include the process of determining the order of nucleotide bases (A, C, G, or T) in a DNA sample, which can be further divided into de novo sequencing, re-sequencing, and tag sequencing. In de novo sequencing, the goal is to determine the sequence of a representative sample from a species never before sequenced. Understanding the similarities and differences in DNA sequence between many species can help our understandingstudy of the function of the protein structures encoded in the DNA.
In re-sequencing, the sequence of nucleotide bases is compared to a standard or reference sequence from a given species to identify changescells, tissues, organs, systems, and other components that reflect genetic variation. Re-sequencing studies can be performed on a genome-wide basis, which is referred to as whole-genome re-sequencing, or on targeted areas of the genome (for example, regions identified by genome-wide association studies), which is known as targeted re-sequencing.make up living organisms. This is an extremely comprehensive form of genetic analysis, in which every base is characterized for possible mutations. We believe that these underlying discoveries will likely feed theresearch supports development of new, array productsmore effective clinical diagnostics and medicines to improve human health, as well as advances in agriculture and animal husbandry to meet the world’s growing needs for broader testingfood and biomarker validation.energy.

In tag sequencing, short sequences, often representativeMolecular Diagnostics Primer

Molecular diagnostic assays (or tests) are designed to identify the biological indicators linked with disease and drug response, providing physicians with information to more effectively diagnose, treat, and monitor both acute and chronic disease conditions. They are an integral part of a larger moleculepersonalized healthcare, where the unique makeup of each individual can be taken into account in diagnosing disease and managing treatment through the use of more tailored therapies. Biological indicators that can be measured by these assays include protein or genomic location, are detected and counted. In these applications, the number of times that each tag is seen provides quantification of an underlying biological process. As an example, in digital gene expression, one or more tag sequences may be analyzed for each expressed gene,methylation levels, copy number variations, and the number of copies of these tags that are detected in an experiment is a measure of how actively that gene is being expressed in the tissue sample being analyzed. Similarly, a tag sequencing approach known as ChIP sequencing is used to determine the locations and extent of protein and DNA interactions throughout the genome.

SNP Genotyping
SNP genotyping is the process of determining which nucleotide base (A, C, G, or T) is present at a particular site in the genome within any organism. The most common use of SNP genotyping is for genome-wide association studies (GWAS) to look for an association between DNA sequence variants and a specific phenotype of interest. This is commonly done by studying the DNA of individuals that are affected by a common disease or that exhibit a specific trait against the DNA of control individuals who do not have this disease or trait. The use of SNP genotyping to obtain meaningful statistics on the effect of an individual SNP or a collection of SNPs requires the analysis of millions of SNP genotypes and the testing of large populations for each disease. For example, a single large study could involve genotyping more than 1,000,000 SNPs per sample in more than 1,000 samples, thus requiring one billion assays. Using previously available technologies, this scale of SNP genotyping was both impractical and prohibitively expensive.
Large-scale SNP genotyping can be used in a variety of ways, including studies designed to understand the genetic contributions to disease (disease association studies), genomics based drug development, clinical trial analysis (responders and non-responders, and adverse event profiles), disease predisposition testing, and disease diagnosis. SNP genotyping can also be used outside of healthcare, for example in the development of plants and animals with commercially desirable characteristics. These markets will require billions of SNP genotyping assays annually.
Gene Expression Profiling
Gene expression profiling is the process of determining which genes are active in a specific cell or group of cells and is accomplished by measuring mRNA, the intermediary messenger between genes and proteins. Variation in gene expression can cause disease, or act as an important indicator of disease or predisposition to disease. By comparing gene expression patterns between cells from different environments, such as normal tissue compared to diseased tissue or in the presence or absence of a drug, specific genesgene or groupsgroup of genes that play a role in these processes can be identified. Studiesgenes.

There are molecular diagnostics assays on the market, including assays for infectious disease, cancer, and preferably tens of thousands, of mRNAs in large numbers of samples. Once a smaller set of genes of interest has been identified, researchers can then examine how these genes are expressed or suppressed across numerous samples, for example, within a clinical trial.
As gene expression patterns are correlated to specific diseases, gene expression profiling is becoming an increasingly important diagnostic tool. Diagnostic use of expression profiling tools is anticipated to grow rapidly with the combination of the sequencing of various genomes and the availability of more cost-effective technologies.
Molecular Diagnostics
Molecular diagnostics is the process of examining nucleic acids, including DNA and RNA, and protein biomarkers to detect or identify infectious diseases, genetic diseases and disorders, human cancers, and to help understandsubject-to-subject, gene-based variation in the efficacy or safety of drug substances (pharmacogenics). As knowledge of the genome and its function continues to expand, new medical and diagnostic applications are being developed. Molecular diagnostic tests can be used as diagnostic toolsheart disease, as well as in genetic disease susceptibility testing. Molecular diagnostic tests can also be used to identify a disease, monitor its progressionmolecular-based drug metabolism and response assays to treatment,help physicians select the most effective therapy with the fewest side effects. Our innovative technologies and products are contributing to the development of a wide range of potential genomic-based molecular diagnostics assays.

Growing news coverage about the clinical relevance of newly discovered genetic markers has prompted consumer interest in having personal genomes analyzed, sparking the development of the consumer genomics market. We believe there are distinct medical benefits, especially for people with family histories of certain diseases, of knowing potential disease predispositions. Several companies, including Illumina, now offer personal sequencing or predict individual predispositiongenotyping services, working with physician groups and genetic counselors to interpret the results for consumers.

We believe the growth in consumer genomics and the use of genomic-based diagnostic assays will trigger a diseasefundamental shift in the practice of medicine and individual response to treatment. By identifying small, individual genetic differences — or variants — that lie at the rooteconomics of differing drug responses,the pharmaceutical industry and health care by facilitating an increased emphasis on preventative and predictive molecular diagnostic tests can be used to select appropriate medication and dosage.medicine, ushering in the era of personalized medicine.

In December 2012, we submitted a 510(k) application for a version of our BeadXpress instrument platform for review byMiSeq system (the MiSeqDx) to the U.S. Food and Drug Administration, (FDA). Assumingor FDA, approval of this instrument platform, we plan to develop clinical diagnostic testing panelsfor marketing as a cleared device for use with in vitro diagnostic (IVD) products. In connection with our FDA submission of the MiSeqDx system, we submitted two cystic fibrosis (CF) assays - a diagnostic assay and a carrier screening assay - to the FDA that, if cleared, would be sold as IVD kits to be run on the BeadXpress instrument platform, including possible panelsMiSeqDx system. The MiSeqDx Cystic Fibrosis Diagnostic Assay is designed for multi-drug resistant organisms, herpes,simultaneous detection of all mutations and respiratory viruses, and we expect to continue research intovariants within the potential development of cancer diagnostic panels, initially focusing on ovarian cancer and gastric cancer. In addition, during the fourth quarter of 2009 we made a pre-IDE (investigational device exemption) submission with the FDA for a cytogeneticscystic fibrosis transmembrane conductance regulator (CFTR) gene. The test is intended to be used as an aid in the postnatal diagnosis of chromosomal abnormalities knownindividuals with suspected CF or congenital bilateral absence of vas deferens (CBAVD). Results of this test are intended to be associatedinterpreted by a certified clinical molecular geneticist or equivalent. The MiSeqDx Cystic Fibrosis Carrier Screening Assay is designed for simultaneous detection of clinically relevant variants within the CFTR gene, including those currently recommended for carrier screening purposes by the American College of Medical Genetics (ACMG) and the American College of Obstetricians and Gynecologists (ACOG). The test is intended to be used in general population screening to determine CF carrier status, as an aid in newborn screening for CF, and as an initial genetic test to aid in the diagnosis of individuals with developmental delaysuspected CF or CBAVD.

As the molecular diagnostics market continues to evolve and mental retardation. The pre-IDE package includedemerge, we believe the translational market will prove to be another growth opportunity for us. In September 2012, Illumina introduced TruSight content sets for use by laboratories with next-generation sequencing systems such as the MiSeq. Comprised of oligonucleotide probes targeting genes and gene regions thought to be relevant for specific genetic diseases or conditions, TruSeq content sets are designed for use by laboratories in the development of their own unique targeted sequencing tests.

Consumer Genomics Markets

New sequencing and genotyping technologies, such as those developed by Illumina, are driving down the cost of performing comprehensive sequencing and genotyping analyses, rapidly paving the way to improving diagnosing of diseases and evaluation of disease risk. Consumer genomics is a nascent market, but one we believe has the potential for high growth as the cost per analysis continues to drop. In 2009, we launched our iScan instrument platform togetherIndividual Genome Sequencing Service, the first physician-intermediated personal genome sequencing service for consumers. Built around physician-patient consultation, the service requires a physician’s order to initiate the process, with associated microarrays, reagents, and software. Following completion of the IDE process, we intend to seek FDA clearance for the iScan instrument platform and related reagents.genome sequencing performed using our CLIA-certified, CAP-accredited laboratory.

Our Principal Technologies

Our unique technology platforms enable the scale of experimentation necessary for genome-wide discovery, target selection, and validation studies (see Figure 1 below). More than 8,000 customer-authored scientific papers have been published to date using these technologies, representing the efforts of a large and dynamic Illumina user community. Through rapid innovation, we are changing the economics of genetic research, enabling projects that were previously considered unapproachable.

Figure 1: Illumina Platform Overview:

Sequencing Technology

DNA sequencing is the process of determining the order of nucleotide bases (A, C, G, or T) in a DNA sample. Our HiSeq 2500/2000, HiSeq 1500/1000, Genome Analyzer IIx, MiSeq, and HiScanSQ systems represent a family of systems that we believe are setting the standard for productivity, cost-effectiveness, and accuracy among next-generation sequencing technologies. They are used by customers to perform whole-genome, de novo, and targeted re-sequencing of genomes, and to analyze specific gene regions and genes.

Whole-genome sequencing determines an organism’s complete DNA sequence. In de novo sequencing, the goal is to sequence a representative sample from a species never before sequenced. In targeted re-sequencing, a sequence of nucleotide bases is compared to a standard or reference sequence from a previously sequenced species to identify changes that reflect genetic variation. Understanding the similarities and differences in DNA sequence between and within species furthers our understanding of the function of the structures encoded in the DNA.

Our DNA sequencing technology is based on the use of our proprietary reversible terminator-based sequencing chemistry, referred to as sequencing by synthesis (SBS) biochemistry. Our SBS biochemistry. In SBS, single stranded DNA is extended fromsequencing technology provides researchers with a priming site, one base at a time, using reversible terminator nucleotides. These are DNA bases that can be added to a growing second strand, but which initially cannot be further extended. This means that at each cyclebroad range of the chemistry, only one base can be added. Each base that is added includes a fluorescent label that is specific to the particular base (A, C, G, or T). Thus, following incorporation, the fluorescence can be imaged, its color determined,applications and the base itself can be inferred. Once this is done, an additional step removes bothability to sequence even large mammalian genomes in days rather than weeks or years. Our highest throughput sequencing instrument, the fluorescence andHiSeq 2500, has the blocking group that had prevented further extension of the second strand. This allows another baseability to be added, and the cycle can then be repeated. Our technology is capable of generating over 100 billion basesgenerate up to 600 gigabases (Gb) (five human genomes) of DNA sequence fromin ten days, or up to 120 Gb in approximately one day in rapid run mode. Since the launch of our first sequencing system in 2007, our systems have reduced the cost of sequencing by more than a single experiment with a single sample preparation. The reversible terminator bases that we use are novel synthetic molecules that we manufacture. They are not well incorporated by naturally occurring polymerases, so we have also developed proprietary polymerase enzymes for this purpose. Both the nucleotides and enzymes are the subjectfactor of significant intellectual property owned by us.100.

In our DNA sequencing systems, we apply the SBS biochemistry on microscopic islands of DNA, referred to as DNA clusters. Each cluster starts as a single DNA molecule fragment, typically a few hundred bases long, attached to the inside surface of a flow cell. We then use a proprietary amplification biochemistry to create copies of each starting molecule. As the copies are made, they are covalently linked to the surface, so they cannot diffuse away. After a number of cycles of amplification, each cluster might have approximately 1,000 copies of the original starting molecule, but still be only about a micron (one-millionth of a meter) in diameter. By making so many copies, the fluorescent signal from each cluster is significantly increased. Because the clusters are so small, hundreds of millions of clusters can be independently formed inside a single flow cell. This large number of clusters can then be sequenced simultaneously by alternate cycles of SBS biochemistry and fluorescent imaging. Sequence reads are aligned against a reference genome and genetic differences are called using specially developed data analysis software.
BeadArray Technology

Our BeadArray technology combines microscopic beads and a substrate in a simple, proprietary manufacturing process to produce arrays that can perform many assays simultaneously, enabling large-scale analysis of genetic variation and biological function in a unique high-throughput, cost effective, and flexible manner. The arrays manufactured using BeadArray technology are imaged by our iScan, HiScan, and HiScanSQ systems for a broad range of DNA and RNA analysis applications including SNP discovery, SNP genotyping, CNV analysis, gene expression analysis, and methylation analysis.

Our proprietary BeadArray technology consists of microscopic silica beads, with each bead covered with hundreds of thousands of copies of oligonucleotides, or oligos, that act as the capture sequences in one of our assays. We deploy our BeadArray technology on BeadChips - silicon wafers the size of a microscope slide, with varying numbers of sample sites per slide. BeadChips are chemically etched to create tens of millions of wells for each sample site.


8


Using our BeadArray technology, we achieve high-throughput analysis with a high density of test sites per array, and we are able to format arrays in various configurations in the format of standard microscope slides.configurations. We seek to maximize cost effectiveness by reducing consumption of expensive reagentsconsumables and valuable samples, and through the low manufacturing costs associated with our technologies. Our ability to vary the size, shape, and format of the well patterns and to create specific bead pools or sensors, for different applications provides the flexibility to address multiple markets and market segments. We believe that theseThese features have enabledenable our BeadArray technology to become a leading platform for thebe applied to high-growth marketmarkets of SNP genotyping and CNV analysis and have allowed us to be a key player in the gene expression market.

Eco Real-Time PCR Technology

In 2010, we purchased Helixis and its novel real-time PCR technology and introduced the Eco Real-Time PCR System to the market. Real-Time PCR (also known as quantitative PCR or qPCR) is used to amplify and simultaneously quantify a targeted DNA molecule, with applications in gene expression, viral quantification, array data validation, pathogen detection, and genotyping. The procedure follows the same steps as PCR, whereby thermal cycling (alternately heating and cooling the DNA sample from 20 to 40 times) causes the DNA to self-replicate, resulting in the doubling of DNA product with each cycle. Real-time PCR uses various fluorescent detection chemistries to enable the monitoring of the PCR reaction as it progresses. Data are collected at each cycle rather than at the end of the reaction, providing higher precision, increased sensitivity, increased dynamic range, and higher resolution.

The Eco System combines a proprietary thermal system, four-color multiplex capabilities, and a fine-tuned optical system to deliver accurate qPCR results. Its unique design provides superior thermal uniformity, supporting high-quality PCR performance for demanding applications such as high resolution melt (HRM) curve analysis used for SNP genotyping, DNA fingerprinting, species identification, HLA compatibility typing, allelic prevalence, and DNA methylation analysis. Measuring just over one cubic foot in size, we believe the Eco System’s overall performance rivals larger, more expensive systems.

Our proprietary BeadArray technology consists of 2-micron silica beads that self-assemble into microwells etched into an array substrate. We have deployed our BeadArray technology in two different array formats, the Array Matrix and the BeadChip. Our first bead based product was the Array Matrix, which incorporates fiber optic bundles comprised of approximately 50,000 individual fibers, with 96 of these bundles placed into an aluminum plate to form an Array Matrix. In late 2009, we announced that during 2010 we would no longer sell Array Matrix products and would instead deploy our BeadArray technology only on BeadChips. BeadChips are microscope slide-size silicon wafers with varying numbers of sample sites per slide. BeadChips are chemically etched to create tens of millions of wells for each sample site.Products
In a separate process, we create sensors by affixing hundreds of thousands of copies of a specific type of oligonucleotide molecule to each of the billions of microscopic beads in a batch. We make different batches of


8


beads, with the beads in a given batch coated with one particular type of molecule. The particular molecules on a bead define that bead’s function as a sensor.
To form an array, a pool of coated beads is brought into contact with the array surface where they are randomly drawn into the wells, one bead per well. The beads in the wells comprise our individual arrays. Because the beads assemble randomly into the wells, we perform a final procedure called “decoding” in order to determine which bead type occupies which well in the array. We employ several proprietary methods for decoding, which is a process that requires only a few steps to identify all the beads in the array. One beneficial by-product of the decoding process is a functional validation of each bead in the array. This quality control test characterizes the performance of each bead and can identify and eliminate use of any empty wells. We ensure that each bead type on the array is sufficiently represented by including multiple copies of each bead type. Multiple bead type copies improve the reliability and accuracy of the resulting data by allowing statistical processing of the results of identical beads.
An experiment is performed by preparing a sample, such as DNA, and introducing it to the array. The molecules in the sample bind to their matching molecules on the coated beads. The molecules in either the sample or on the bead are labeled with fluorescent dye either before or after the binding, which can be detected by shining a laser on the BeadChip. This allows the detection of the molecules resulting in a quantitative analysis of the sample.
VeraCode Technology
Our proprietary VeraCode technology platform leverages the power of digital holographic codes to provide a robust detection method for multiplex assays requiring high precision, accuracy, and speed. VeraCode enables low-cost multiplexing from 1 to 384-plex in a single well. At the heart of the VeraCode technology are cylindrical glass beads measuring 240 microns in length by 28 microns in diameter. Each VeraCode bead type is inscribed with a unique digital holographic code to designate and track the specific analyte or genotype of interest throughout the multiplex reaction. When excited by a laser, each VeraCode bead emits a unique code image, allowing for quick and specific detection by Illumina’s BeadXpress Reader System. Depending on desired multiplex levels, assays are created by pooling microbeads with code diversities from one to several hundred. Unlike traditional microarrays, the VeraCode microbeads are used in solution, which takes advantage of solution-phase kinetics for more rapid hybridization times, dramatically reducing the time to achieve results. This technology enables us to serve a number of markets including research, agriculture, forensics, pharmaceuticals, and molecular diagnostics.
Our Products
Using our proprietary technologies, our products give our customers the ability to analyze the genome at any level of complexity, from whole genomewhole-genome sequencing to low multiplex assays.

Our Services
Sequencing
We have been offeringdeveloped a variety of sample preparation and sequencing kits to simplify workflows and accelerate analysis. Some provide all the necessary consumables needed for analyses, such as our Standard Sequencing Kit (SBS chemistry on our sequencing platforms) and Infinium Assay Kit (array-based genotyping on our array platforms). Others support more discrete analyses, such as our Paired-End Genomic DNA Sample Prep Kit for streamlining library preparation for the generation of 200-500 kb insert paired-end reads for sequencing, gene expression, and epigenetic analysis. Our TruSeq SBS Sequencing Kit enhances sequencing studies with our HiSeq, Genome Analyzer IIx, and MiSeq systems, by enabling researchers to extend the read lengths, achieve higher Gb of mappable data, and deliver the highest yield of perfect reads to maximize the ability to accurately characterize the genome. Through our acquisition of Epicentre Technologies Corporation in 2011, we acquired the proprietary Nextera technology for next-generation sequencing library preparation. This technology has enabled us to offer sequencing library preparation kits with lower sample input requirements that greatly simplify genetic analysis workflows and significantly reduce the time from sample preparation to answer.

Our InfiniumHD Whole-Genome BeadChips represent our most technologically advanced multi-sample DNA analysis microarrays, enabling the interrogation of up to approximately 5 million markers per sample, depending on the BeadChip. The most recent additions to the Omni family, the HumanOmni5-Quad, the HumanOmni2.5, and the HumanOmni1S BeadChips, provide comprehensive coverage of common and rare variants identified by the 1000 Genomes Project for performing rich GWAS projects. This product line also includes agriculturally relevant genome panels such as the BovineHD and MaizeSNP50 BeadChips.

For researchers who want to study focused genomic regions of interest, or are interested in organisms for which there are no standard products, we offer iSelect Custom Genotyping BeadChips. Easily developed to fit any experimental design, these SNP genotyping arrays can be used to investigate from 3,000 to 1,000,000 markers targeting any species.

Service Partnership Programs

To complement our own service capabilities, we have developed partnered programs such as our Certified Service Providers (CSPro) and Illumina Genome Network (IGN), to create a world-wide network of Illumina technology-enabled service offerings that broaden our market reach. Illumina CSPro is a collaborative service partnership established between Illumina and leading genome centers and research laboratories to ensure the delivery of high-quality genetic analysis services. It provides a competitive advantage for service providers, while also ensuring that customers will receive Illumina data quality and service. To become a CSPro provider, participating laboratories must complete a three-phased Illumina certification process. There are over 65 Illumina CSPro-certified organizations worldwide providing sequencing, genotyping, and gene expression services using our technologies and products.

Introduced in 2010, the IGN links researchers interested in conducting large whole genome sequencing projects with leading institutes worldwide that possess our next-generation sequencing technology. The IGN provides a cost-effective and dependable way to complete large sequencing projects. All IGN partners are experienced and well-published using Illumina technology, and each has completed Illumina’s Certified Service Provider (CSPro) certification. Each IGN partner possesses ten or more high-throughput Illumina sequencing systems, providing the scalability to handle even the largest sequencing projects with rapid completion times. Current members include: the Broad Institute, British Columbia Cancer Agency’s Genome Science Centre, Cold Spring Harbor Laboratory, University of Washington Department of Genome Sciences, National Center for Genome Resources, Macrogen/Genomic Medicine Institute, and Illumina’s own FastTrack Services.

Individual Genome Sequencing

Since June 2009, Illumina's Clinical Services Laboratory has been offering the Individual Genome Sequencing Service providing personal genome sequencing from our CLIA-certified, CAP-accredited laboratory using Illumina next-generation sequencing technology.  We offer a variety of reporting options. The Individual Genome Sequencing Service requires individuals to follow our physician-mediated process, which involves pre-service consultation and informed consent that includes review of the information potentially to be learned in the report. The final genome data is returned to the physician who then meets with the patient and discusses implications and possible actions based on the results. If the physician and patient agree, the information can also be downloaded to the individual's personal iPad® for additional exploration. We are collaborating with a number of partners to provide additional evaluations, such as ancestry, and information on traits of interest.

Intellectual Property

We have an extensive intellectual property portfolio, including, as of February 1, 2010,2013, ownership of, or exclusive licenses to, 159270 issued U.S. patents and 171172 pending U.S. patent applications, including eight11 allowed applications that have not yet issued as patents.  Our issued patents include those directed to various aspects of our arrays, assays, oligo synthesis, sequencing technology, instruments, and chemical detection technologies, and have terms that expire between 20102013 and 2027.2030.  We continue to file new patent applications to protect the full range of our technologies.  We have filed or have been granted counterparts for many of these patents and applications in foreign countries.

We also rely upon trade secrets, know-how, copyright, and trademark protection, as well as continuing technological innovation and licensing opportunities to develop and maintain our competitive position.  Our success will depend in part on our ability to obtain patent protection for our products and processes, to preserve our trade secrets, to enforce our patents, copyrights and trademarks, to operate without infringing the proprietary rights of third parties, and to acquire licenses related to enabling technology or products.

We are party to various exclusive and non-exclusive license agreements and other arrangements with third parties that grant us rights to use key aspects of our array and sequencing technologies, assay methods, chemical detection methods, reagent kits, and scanning equipment.  We have exclusive licenses from Tufts University to patents that are directed to our BeadArray technology.  These patents were filed by Dr. David Walt, who is a member of our board of directors, the Chairman of our Scientific Advisory Board, and one of our founders.  Our exclusive licenses expire with the termination of the underlying patents, which will occur between 20102013 and 2020.  We have additional nonexclusive license agreements with various third

11


parties for other components of our products.  In most cases, the agreements remain in effect over the term of the underlying patents, may be terminated at our request without further obligation, and require that we pay customary royalties while the agreement is in effect.

Research and Development

We have made substantial investments in research and development since our inception. We have assembled a team of skilled engineersscientists and scientistsengineers who are specialists in biology, chemistry, informatics, instrumentation, optical systems, software, manufacturing, and other related areas required to complete the development of our products. Our research and development efforts have focused primarily on the tasks required to optimize our sequencing, BeadArray, VeraCode, and oligo synthesis technologies and to support commercialization of the products and services derived from theseour technologies.

Our research and development expenses for 2009, 2008,fiscal 2012, 2011, and 20072010 were $140.6$231.0 million $100.0, $196.9 million, and $73.9$177.9 million, respectively. We expect research and development expense to increase during 20102013 as a result of the growth of our business and as we continue to expand our research and product development efforts.

Marketing and Distribution

Our current products address the genetic analysis portion of the life sciences market, in particular, experiments involving sequencing, SNP genotyping, and gene expression profiling. These experiments may be


12


involved in many areas of biologic research, including basic human disease research, pharmaceutical drug discovery and development, pharmacogenomics, toxicogenomics, and animal and agricultural research. Our potential customers include pharmaceutical, biotechnology, agrichemical, diagnostics,leading genomic research centers, academic institutions, government laboratories, and consumer products companies,clinical research organizations, as well as academic or private research centers.pharmaceutical, biotechnology, agri-genomics, and consumer genomics companies. The genetic analysis market is relatively new and emerging and its size and speed of development will ultimately be driven by, among other items:
• the ability of the research community to extract medically valuable information from genomics and to apply that knowledge to multiple areas of disease-related research and treatment;
• the availability of sufficiently low cost, high-throughput research tools to enable the large amount of experimentation required to study genetic variation and biological function; and
• the availability of government and private industry funding to perform the research required to extract medically relevant information from genomic analysis.
the availability of sufficiently low cost, high-throughput research and analysis tools to enable the large amount of experimentation and analysis required to study genetic variation and biological function; and
the availability of government and private industry funding to perform the research required to extract medically relevant information from genomic analysis.

We market and distribute our products directly to customers in North America, Europe, Latin America, and the Asia-Pacific region. In each of these areas, we have dedicated sales, service, and application support personnel responsible for expanding and managing their respective customer bases. In addition, in certain markets within Europe, the Asia-Pacific region, Latin America, the Middle East, and South Africa we sell our products and provide services to customers through distributors that specialize in life science products. Likewise, in the United States we sell our qPCR portfolio (including the Eco Real-Time PCR System and associated reagents) through a distributor. We expect to continue to increase our sales and distribution resources during 20102013 and beyond as we launch a number of new products and expand the number of customers that can use our products.

Manufacturing

We manufacture sequencing and array instrument platforms, reagent kits, scanning equipment, and oligos. Our manufacturing capacity for consumables and instruments has grown during 20092012 to support our increased customer demand. We are also focused on continuing to enhance the quality and manufacturing yield of our BeadChips and flow cells. To continue to increase throughput and improve the quality and manufacturing yield as we increase the complexity of our products, we are exploring ways to continue increasing the level of automation in the manufacturing process. We adhere to access and safety standards required by federal, state, and local health ordinances, such as standards for the use, handling, and disposal of hazardous substances.

Raw Materials

Our manufacturing operations require a wide variety of raw materials, electronic and mechanical components, chemical and biochemical materials, and other supplies. We have multiple commercial sources for many of our components and supplies; however, there are some raw materials and components that we obtain from single source suppliers. To mitigate potential risks arising from single source suppliers, we believe that we can redesign our products for alternative components or

12


use alternative reagents.reagents, if required. In addition, while we generally attempt to keep our inventory at minimal levels, we purchase incremental inventory as circumstances warrant to protect our supply chain.

Competition

Although we expectbelieve that our products and services will provide significant advantages over products and services currently available from other sources, we expect to continue to encounter intense competition from other companies that offer products and services for the sequencing, SNP genotyping, gene expression, and molecular diagnostics markets. These include companies such as Affymetrix, Inc.; Agilent Technologies, Inc.; Beckman Coulter, Inc.; Complete Genomics, Inc.; General Electric Company; Helicos BioSciences Corporation; Life Technologies Corporation; Luminex Corporation; Pacific Biosciences of California, Inc.; QIAGEN N.V.; and Roche Diagnostics Corp.; Sequenom, Inc.; and Qiagen N.V., among others. Some of these companies have or will have substantially greater financial, technical, research, and other resources and larger, more established marketing, sales, distribution, and service organizations than we do. In addition, they may have greater name recognition than we do in the markets we address and in some cases a larger installed base of systems. Each of these markets is very competitive and we expect new competitors to emerge and the intensity of competition to increase. In

order to effectively compete with these companies, we will need to demonstrate that our products have superior throughput, cost, and accuracy advantages over competing products.

Segment and Geographic Information

DuringIn accordance with the first quarterauthoritative accounting guidance for segment reporting, we have determined that we have two operating segments for purposes of 2008, we reorganizedrecording and reporting our operating structure into two newly created business segments,financial results: Life Sciences and Diagnostics. Our Life Sciences Business Unitoperating segment includes all products and services that are primarily related to the research market, namely the product lines based on our sequencing, BeadArray,array, and VeraCode technologies, and ourreal-time PCR technologies. Our Diagnostics Business Unitoperating segment focuses on the emerging opportunity in molecular diagnostics. During 2009, weall periods presented, our Diagnostics operating segment had limited activity related to the Diagnostics Business Unit andactivity. Accordingly, our financial results for both operating results weresegments are reported on an aggregate basis to our chief operating decision maker, the chief executive officer. Accordingly, we operated inas one reportable segment. We will begin reporting in two operating segments once revenues, operating profit or loss, or assets of the Diagnostics operating segment during 2009.exceed 10% of the consolidated amounts.

We currently sell our products to a number of customers outside the United States, including customers in other areas of North America, Europe, and the Asia-Pacific region. Shipments to customers outside the United States totaled $319.1$580.1 million, or 48%51% of our total revenue, during 2009,fiscal 2012, compared to $293.2$526.8 million, or 51%50%, and $159.1$403.8 million, or 43%45%, in 2008fiscal 2011 and 2007,2010, respectively. SalesThe U.S. dollar has been determined to customers outsidebe the functional currency of the United States were generally denominated in U.S. dollars. In 2008, we reorganized ourCompany’s international structureoperations due to establish more efficient channels among product development, product manufacturing, and sales. The reorganization increased our foreign subsidiaries’ anticipated dependence on the U.S. entity for management decisions, financial support, production assets, and inventory thereby making the foreign subsidiaries more of a direct and integral component of the U.S. entity’s operations. As a result, we reassessed the primary economic environment of our foreign subsidiaries and determined the subsidiaries are more U.S. dollar based, resulting in a U.S. dollar functional currency determination.subsidiaries. We expect that sales to international customers will continue to be an important and growing source of revenue. See Note 13note “15. Segment Information, Geographic Data, and Significant Customers” in Part II, Item 8 of the Notes to Consolidated Financial Statementsthis Form 10-K for further information concerning our foreign and domestic operations.

Backlog

Our backlog was $227.6approximately $260 million and $113.0$251 million at December 30, 2012 and January 3, 2010 and December 28, 2008,1, 2012, respectively. Generally, our backlog consists of orders believed to be firm as of the balance sheet date; however, we may allow customers to make product substitutions as we launch new products. The timing of shipments depends on several factors, including agreed upon shipping schedules, which may span multiple quarters, and whether the product is catalog or custom. We reasonably expect an estimated 90%the majority of the backlog as of January 3, 2010December 30, 2012 to be shipped within the fiscal year ending January 2, 2011.December 29, 2013. Although we generally recognize revenue atupon the time of shipment and transfer of title to a customer, we may be required to defer the recognition of revenue even after shipmenttitle transfer depending on the specific arrangement with a customer and the applicable accounting treatment. A material portion of our backlog at January 3, 2010 is associated with a large order we received from one customer for which we anticipate using operating lease accounting that will require us to recognize revenue over a period of three years with the majority of that revenue recognized in 2011 and 2012.

Seasonality

Historically, customer purchasing patterns have not shown significant seasonal variation, although demand for our products is usually lowest in the first quarter of the calendar year and highest in the third quarter of the calendar year as a result, in part, of U.S. academic customers spending unused budget allocations before the end of the U.S. government’s fiscal year on September 30 of each year. However, this historical pattern has decreased during the past two years as a result, in part, of uncertainty concerning government and academic research funding and reduced usage of our consumable products during the summer vacation season.

Environmental Matters

We are committed to the protection of our employees and the environment. Our operations require the use of hazardous materials that subject us to a variety of federal, state, and local environmental and safety laws and regulations. We believe we are in material compliance in all material respects, with current applicable laws and regulations; however, we could be held liable for damages and fines should contamination


14


of the environment or individual exposures to hazardous substances occur. In addition, we cannot predict how changes in these laws and regulations, or the development of new laws and regulations, will affect our business operations or the cost of compliance.

Government Regulation

Our products are not currently subjectAs we continue to FDA clearance or approval if they are not intended to be used for the diagnosis of disease. However, as we expand our product linelines to encompass products that are intended to be used for the diagnosis of disease, such as molecular diagnostic 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, depending on their intended use, will be regulated as medical devices by the FDA and comparable agencies of other countries and may require either receiving clearance following a pre-market notification process, also known as a 510(k) clearance, or premarket approval (PMA), from the FDA prior to marketing. Obtaining the requisite regulatory approvals can be expensive and may involve considerable delay.

The shorter 510(k) clearance process, which generally takes from three to six months after submission, but can take significantly longer, may be utilized if it is demonstrated that the new product is “substantially equivalent” to a similar product that has already been cleared by the FDA. The longer PMA process is much more costly, uncertain, and generally takes from nine months to two years after filing. Because we cannot assure yoube certain that any molecular diagnostic products that we develop will be subject to the shorter 510(k) clearance process, or will ultimately be approved at all, the regulatory approval process for such products may be significantly delayed and may be significantly more expensive than anticipated. If we fail to obtain, or experience significant delays in obtaining, regulatory approvals for molecular diagnostic products that we develop, we may not be able to launch or successfully commercialize such products in a timely manner, or at all.

Changes to the current regulatory framework, including the imposition of 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 or maintain FDA or comparable regulatory approval of our products, if required.

In addition, the regulatory approval or clearance process required to design, manufacture, market, sell, and sellsupport our existing and future products that are intended for, and marketed and labeled as, “Research Use Only,” or RUO, is uncertain if such products are used or could be used, even without our consent, for the diagnosis of disease. If the FDA or other regulatory authorities assert that any of our RUO products are subject to regulatory clearance or approval, our business, financial condition, or results of operations could be adversely affected.

Employees

As of January 3, 2010,December 30, 2012, we had a total of 1,781approximately 2,400 employees. None of our employees are represented by a labor union. We consider our employee relations to be positive. Our success will depend in large part upon our ability to attract and retain employees. In addition, we employ a number of temporary and contract employees. We face competition in this regard from other companies, research and academic institutions, government entities, and other organizations.

ITEM 1A.Risk Factors

Our business is subject to various risks, including those described below. In addition to the other information included in thisForm 10-K, the following issues could adversely affect our operating results or our stock price.

Reduction or delay in research and development budgets and government funding may adversely affect our revenue.

A substantial portion of our revenue is derived from genomic research centers, academic institutions, government laboratories, and clinical research organizations, as well as pharmaceutical, biotechnology, agrigenomics, and consumer genomics companies, and their capital spending budgets can have a significant effect on the demand for our products and services. These budgets are based on a wide variety of factors, including the allocation of available resources to make purchases, funding from government sources, the spending priorities among various types of research equipment, and policies regarding capital expenditures during recessionary periods. Any decrease in capital spending or change in spending priorities of our customers could significantly reduce our revenue. Moreover, we have no control over the timing and amount of

14


purchases by our customers, and, as a result, revenue from these sources may vary significantly due to factors that can be difficult to forecast. Any delay or reduction in purchases by our customers or our inability to forecast fluctuations in demand could harm our future operating results.

The timing and amount of revenues from customers that rely on government and academic research funding may vary significantly due to factors that can be difficult to forecast, and there remains significant uncertainty concerning government and academic research funding worldwide as governments in the United States and Europe, in particular, focus on reducing fiscal deficits while at the same time confronting slowing economic growth. Funding for life science research has increased more slowly during the past several years compared to previous years and has declined in some countries. Government funding of research and development is subject to the political process, which is inherently fluid and unpredictable. Other programs, such as defense, entitlement programs, or general efforts to reduce budget deficits could be viewed by governments as a higher priority. These budgetary pressures may result in reduced allocations to government agencies that fund research and development activities, such as the U.S. National Institute of Health, or NIH. For instance, the significance and timing of anticipated reductions to the NIH budget from March 2013 may be significantly impacted by the sequestration provisions of the Budget Control Act of 2011 and whether these provisions remain in effect. Past proposals to reduce budget deficits have included reduced NIH and other research and development allocations. Any shift away from the funding of life sciences research and development or delays surrounding the approval of government budget proposals may cause our customers to delay or forego purchases of our products, which could adversely affect our business, financial condition, or results of operations.

We face intense competition, which could render our products obsolete, result in significant price reductions, or substantially limit the volume of products that we sell.

We compete with life sciences companies that design, manufacture, and market products for analysis of genetic variation and biological function and other applications using a wide-range of competing technologies. We anticipate that we will continue to face increased competition as existing companies develop new or


15


improved products and as new companies enter the market with new technologies. One or more of our competitors may render our technology obsolete or uneconomical. Some of our competitors have greater financial and personnel resources, broader product lines, a more established customer base, and more experience in research and development than we do. Furthermore, life sciences and pharmaceutical companies, which are our potential customers and strategic partners, could also develop competing products. We believe that customers in our markets display a significant amount of loyalty to their initial supplier of a particular product; therefore, it may be difficult to generate sales to potential customers who have purchased products from competitors. To the extent we are unable to be the first to develop or supply new products, our competitive position may suffer.

The market for molecular diagnostics products is currently limited and highly competitive, with several large companies already having significant market share, intellectual property portfolios, and regulatory expertise. Established diagnostic companies also have an installed base of instruments in several markets, including clinical and reference laboratories, which could deter acceptance of our products. In addition, some of these companies have formed alliances with genomics companies that provide them access to genetic information that may be incorporated into their diagnostic tests.

Our acquisitions expose us to risks that could adversely affect our business, and wemay not achieve the anticipated benefits of acquisitions of businesses ortechnologies.

As part of our strategy to develop and identify new products, services, and technologies, we have made, and may continue to make, acquisitions of technologies, products, or businesses. Acquisitions involve numerous risks and operational, financial, and managerial challenges, including the following, any of which could adversely affect our business, financial condition, or results of operations:
difficulties in integrating new operations, technologies, products, and personnel;
lack of synergies or the inability to realize expected synergies and cost-savings;
difficulties in managing geographically dispersed operations;
underperformance of any acquired technology, product, or business relative to our expectations and the price we paid;
negative near-term impacts on financial results after an acquisition, including acquisition-related earnings charges;
the potential loss of key employees, customers, and strategic partners of acquired companies;

15


claims by terminated employees and shareholders of acquired companies or other third parties related to the transaction;
the issuance of dilutive securities, assumption or incurrence of additional debt obligations or expenses, or use of substantial portions of our cash;
diversion of management’s attention and company resources from existing operations of the business;
inconsistencies in standards, controls, procedures, and policies;
the impairment of intangible assets as a result of technological advancements, or worse-than-expected performance of acquired companies; and
assumption of, or exposure to, unknown contingent liabilities or liabilities that are difficult to identify or accurately quantify.

In addition, the successful integration of acquired businesses requires significant efforts and expense across all operational areas, including sales and marketing, research and development, manufacturing, finance, legal, and information technologies. There can be no assurance that any of the acquisitions we make will be successful or will be, or will remain, profitable. Our failure to successfully address the above risks may prevent us from achieving the anticipated benefits from any acquisition in a reasonable time frame, or at all.

Our success depends upon the continued emergence and growth of markets for analysis of genetic variation and biological function.

We design our products primarily for applications in the life sciences, diagnostic, agricultural, and pharmaceutical industries. The usefulness of our technologies depends in part upon the availability of genetic data and its usefulness in identifying or treating disease. We are focusing on markets for analysis of genetic variation and biological function, namely sequencing, genotyping, and gene expression profiling. These markets are new and emerging, and they may not develop as quickly as we anticipate, or reach their full potential. Other methods of analysis of genetic variation and biological function may emerge and displace the methods we are developing. Also, researchers may not seekbe able to successfully analyze raw genetic data or be able to convert raw genetic data into medically valuable information through the analysis of genetic variation and biological function.information. For instance, demand for our microarray products may be adversely affected if researchers fail to find meaningful correlations between genetic variation, such as SNPs, and disease susceptibility through genome wide association studies. In addition, factors affecting research and development spending generally, such as changes in the regulatory environment affecting life sciences and pharmaceutical companies, and changes in government programs that provide funding to companies and research institutions, could harm our business. If useful genetic data is not available or if our target markets do not develop in a timely manner, demand for our products may grow at a slower rate than we expect, and we may not be able to sustain profitability.

If the quality of our products does not meet our customers’ expectations, then our reputation could suffer and ultimately oursales and operating earnings and ultimately our reputation, could be negativelyimpacted.

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 reagentsconsumables are highly complex, the occurrence of defects may increase as we continue to introduce new products and services and as we 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 continued growth is dependent on continuously developing and commercializing newproducts.

Our target markets are characterized by rapid technological change, evolving industry standards, changes in customer needs, existing and emerging competition, strong price competition, and frequent new product introductions. Accordingly, our continued growth depends on continuously developing and commercializing new products and services, including improving

16


our existing products and services, in order to address evolving market requirements on a timely basis. If we fail to innovate or adequately invest in new technologies, our products and services will become dated, and we could lose our competitive position in the markets that we serve as well ascustomers purchase new products offered by our financial results.competitors. We believe that successfully introducing new products and technologies in our target markets on a timely basis provides a significant competitive advantage because customers make an investment of time in selecting and learning to use a new product and may be reluctant to switch once that selection is made.


16


To the extent that we fail to introduce new and innovative products, or such products are not accepted in the market or suffer significant delays in development, we may lose market share to our competitors, which will be difficult or impossible to regain. An inability, for technological or other reasons, to develop successfully and timely introduce new products could reduce our growth rate or otherwise have an adverse effect on our business. In the past, we have experienced, and are likely to experience in the future, delays in the development and introduction of new products. There can be no assurance that we will keep pace with the rapid rate of change in our markets or that our new products will adequately meet the requirements of the marketplace, achieve market acceptance, or compete successfully with competing technologies. Some of the factors affecting market acceptance of new products and services include:
availability, quality, and price relative to competing products and services;
the functionality and performance of new and existing products and services;
the timing of introduction of new products or services relative to competing products and services;
scientists’ and customers’ opinions of the utility of new products or services;
citation of new products or services in published research;
regulatory trends and approvals; and
general trends in life sciences research and applied markets.

We may also have to write off excess or obsolete inventory if sales of our products are not consistent with our expectations or the market requirements for our products change due to technical innovations in the marketplace.

If we do not successfully manage the development, manufacturing, and launch of new products orservices, including product transitions, our financial results could be adverselyaffected.

We face risks associated with launching new products and pre-announcing products and services when the products or services have not been fully developed or tested. If our products and services are not able to deliver the performance or results expected by our target markets or are not delivered on a timely basis, our reputation and credibility may suffer. If we encounter development challenges or discover errors in our products late in our development cycle, itwe may cause us to delay ourthe product launch date. In addition, we may experience difficulty in managing or forecasting customer reactions, purchasing decisions, or transition requirements or programs (such as trade-in programs) with respect to newly launched products (or products in development) relative to our existing products, which could adversely affect sales of our existing products. The expenses or losses associated with unsuccessful product development or launch activities or lack of market acceptance of our new products could adversely affect our business, financial condition, or results of operations.

We depend on third-party manufacturers and suppliers for components and materialsused in our products, and if shipments from these manufacturers or suppliers aredelayed or interrupted, or if the quality of the components or materials supplied donot meet our requirements, we may not be able to launch, manufacture, or ship ourproducts in a timely manner, or at all.

The complex nature of our products requires customized, precision-manufactured components and materials that currently are available from a limited number of sources, and, in the case of some components and materials, from only a single source. If deliveries from these vendors are delayed or interrupted for any reason, or if we are otherwise unable to secure a sufficient supply, we may not be able to obtain these components or materials on a timely basis or in sufficient quantities or qualities, or at all, in order to meet demand for our products. We may need to enter into contractual relationships with manufacturers for commercial-scale production of some of our products, or develop these capabilities internally, and there can be no assurance that we will be able to do this on a timely basis, in sufficient quantities, or on commercially reasonable terms. In addition, the lead time needed to establish a relationship with a new supplier can be lengthy, and we may experience delays in meeting demand in the event we must switch to a new supplier. The time and effort required to qualify a new supplier could result in additional costs, diversion of resources, or reduced manufacturing yields, any of which would negatively impact our operating results. Accordingly, we may not be able to establish or maintain reliable, high-volume manufacturing at commercially

17


reasonable costs or at all. In addition, the manufacture or shipment of our products may be delayed or interrupted if the quality of the components or materials supplied by our vendors does not meet our requirements. Current or future social and environmental regulations or critical issues, such as those relating to the sourcing of conflict minerals from the Democratic Republic of the Congo or the need to eliminate environmentally sensitive materials from our products, could restrict the supply of components and materials used in production or increase our costs. Any delay or interruption to our manufacturing process or in shipping our products could result in lost revenue, which would adversely affect our business, financial condition, or results of operations.

If we lose our key personnel or are unable to attract and retain additionalpersonnel, we may be unable to achieve our goals.

We are highly dependent on our management and scientific personnel, including Jay Flatley, our President and Chief Executive Officer. The loss of their services could adversely impact our ability to achieve our business objectives. In addition, the continued growth of our business depends on our ability to hire additional qualified personnel with expertise in molecular biology, chemistry, biological information processing, sales, marketing, and technical support. We compete for qualified management and scientific personnel with other life science companies, universities, and research institutions, particularly those focusing on genomics. Competition for these individuals, particularly in the San Diego and San Francisco area, is intense, and the turnover rate can be high. Failure to attract and retain management and scientific personnel would prevent us from pursuing collaborations or developing our products or technologies. Additionally, integration of acquired companies and businesses can be disruptive, causing key employees of the acquired business to leave. Further, we use stock options and restricted stock units to attract key personnel, incentivize them to remain with us, and align their interests with those of the Company by building long-term stockholder value. If our stock price decreases, the value of these equity awards decreases and therefore reduces a key employee’s incentive to stay.

If we are unable to increase our manufacturing capacity and develop and maintainoperation of our manufacturing capability, we may not be able to launch or supportour products in a timely manner, or at all.

We continue to rapidly increase our manufacturing capacity to meet the anticipated demand for our products. Although we have significantly increased our manufacturing capacity and we believe we have plans in place sufficient to ensure we have adequate capacity to meet our current business plan for 2010,plans, there are uncertainties inherent in expanding our manufacturing capabilities, and we may not be able to sufficiently increase our capacity in a timely manner. For example, manufacturing and product quality issues may arise as we increase production rates at our manufacturing facilities and launch new products. Also, we may not manufacture the right product mix to meet customer demand, especially as we introduce new products. As a result, we may experience difficulties in meeting customer, collaborator, and internal demand, in which case we could lose customers or be required to delay new product introductions, and demand for our products could decline. Additionally, in the past, we have experienced variations in manufacturing conditions and quality control issues that have temporarily reduced or suspended production of certain products. Due to the intricate nature of manufacturing complex instruments, consumables, and products that contain DNA, we may encounter similar or previously unknown manufacturing difficulties in the future that could significantly reduce production yields, impact our ability to launch or sell these products (or to produce them economically), prevent us from achieving expected performance levels, or cause us to set prices that hinder wide adoption by customers.

Additionally, we currently manufacture in a limited number of locations. Our manufacturing facilities are located in San Diego and Hayward, California; Madison, Wisconsin; Singapore; and Little Chesterford,Cambridge, United Kingdom. These areas are subject to natural disasters such as earthquakes, wildfires, or floods. If a natural disaster were to damage one of our facilities significantly or if other events were to cause our operations to fail, we may be unable to manufacture our products, provide our services, or develop new products.

Also, many of our manufacturing processes are automated and are controlled by our custom-designed Laboratory Information Management Systemlaboratory information management system (LIMS). Additionally, the decoding process in our array manufacturing requires significant network and storage infrastructure. If either our LIMS system or our networks or storage infrastructure were to fail for an extended period of time, it may adversely impact our ability to manufacture our products on a timely basis and could prevent us from achieving our expected shipments in any given period.

Any inability to effectively protect our proprietary technologies could harm ourcompetitive position.

Our acquisitions exposesuccess depends to a large extent on our ability to develop proprietary products and technologies and to obtain patents and maintain adequate protection of our intellectual property in the United States and other countries. If we do not protect our intellectual property adequately, competitors may be able to use our technologies and thereby erode our competitive advantage. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and

18


many companies have encountered significant challenges in establishing and enforcing their proprietary rights outside of the United States. These challenges can be caused by the absence of rules and methods for the establishment and enforcement of intellectual property rights outside of the United States.

The proprietary positions of companies developing tools for the life sciences, genomics, agricultural, and pharmaceutical industries, including our proprietary position, generally are uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. We intend to apply for patents covering our technologies and products as we deem appropriate. However, our patent applications may be challenged and may not result in issued patents or may be invalidated or narrowed in scope after they are issued. Questions as to inventorship or ownership may also arise. Any finding that our patents or applications are unenforceable could harm our ability to prevent others from practicing the related technology, and a finding that others have inventorship or ownership rights to our patents and applications could require us to risksobtain certain rights to practice related technologies, which may not be available on favorable terms, if at all. Furthermore, as issued patents expire, we may lose some competitive advantage as others develop competing products, and, as a result, we may lose revenue.

In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products and may therefore fail to provide us with any competitive advantage. We may need to initiate lawsuits to protect or enforce our patents, or litigate against third party claims, which would be expensive, and, if we lose, may cause us to lose some of our intellectual property rights and reduce our ability to compete in the marketplace. Furthermore, these lawsuits may divert the attention of our management and technical personnel. There is also the risk that others may independently develop similar or alternative technologies or design around our patented technologies. In that regard, certain patent applications in the United States may be maintained in secrecy until the patents issue, and publication of discoveries in the scientific or patent literature tend to lag behind actual discoveries by several months.

We also rely upon trade secrets and proprietary know-how protection for our confidential and proprietary information, and we have taken security measures to protect this information. These measures, however, may not provide adequate protection for our trade secrets, know-how, or other confidential information. Among other things, we seek to protect our trade secrets and confidential information by entering into confidentiality agreements with employees, collaborators, and consultants. There can be no assurance that any confidentiality agreements that we have with our employees, collaborators, and consultants will provide meaningful protection for our trade secrets and confidential information or will provide adequate remedies in the event of unauthorized use or disclosure of such information. Accordingly, there also can be no assurance that our trade secrets will not otherwise become known or be independently developed by competitors.

Litigation, other proceedings, or third party claims of intellectual propertyinfringement could require us to spend significant time and money and could preventus from selling our products or services.

Our success depends, in part, on our non-infringement of the patents or proprietary rights of third parties. Third parties have asserted and may in the future assert that we are employing their proprietary technology without authorization. As we enter new markets or introduce new products, we expect that competitors will likely claim that our products infringe their intellectual property rights as part of a business strategy to impede our successful competition. In addition, third parties may have obtained and may in the future obtain patents allowing them to claim that the use of our technologies infringes these patents. We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against any of these claims. Any adverse ruling or perception of an adverse ruling in defending ourselves against these claims could have an adverse impact on our stock price, which may be disproportionate to the actual import of the ruling itself. Furthermore, parties making claims against us may be able to obtain injunctive or other relief, which effectively could block our ability to develop further, commercialize, or sell products or services, and could result in the award of substantial damages against us. In the event of a successful infringement claim against us, we may be required to pay damages and obtain one or more licenses from third parties, or be prohibited from selling certain products or services. In addition, we may be unable to obtain these licenses at a reasonable cost, if at all. We could therefore incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins. In addition, we could encounter delays in product introductions while we attempt to develop alternative methods or products. Defense of any lawsuit or failure to obtain any of these licenses on favorable terms could prevent us from commercializing products, and the prohibition of sale of any of our products or services could adversely affect our ability to grow or maintain profitability.

Our products, if used for the diagnosis of disease, could be subject to governmentregulation, and the regulatory approval and maintenance process for such products maybe expensive, time-consuming, and uncertain both in timing and in outcome.


19


Products are not subject to FDA clearance or approval if they are not intended to be used for the diagnosis of disease. However, as we expand our product line to encompass products that are intended to be used for the diagnosis of disease, certain of our products will become subject to regulation by the FDA, or comparable agencies of other countries, including requirements for regulatory clearance or approval of such products before they can be marketed. Such regulatory approval processes or clearances may be expensive, time-consuming, and uncertain, and our failure to obtain or comply with such approvals and clearances could have an adverse effect on our business, financial condition, or operating results. In addition, changes to the current regulatory framework, including the imposition of 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 or maintain FDA or comparable regulatory approval of our products, if required.

Molecular diagnostic products, in particular, depending on their intended use, may be regulated as medical devices by the FDA and comparable agencies of other countries and may require either receiving clearance from the FDA following a pre-market notification process or premarket approval from the FDA, in each case prior to marketing. Obtaining the requisite regulatory approvals can be expensive and may involve considerable delay. If we fail to obtain, or experience significant delays in obtaining, regulatory approvals for molecular diagnostic products that we develop, we may not achievebe able to launch or successfully commercialize such products in a timely manner, or at all.

In addition, the anticipated benefitsregulatory approval or clearance process required to design, manufacture, market, sell, and support our existing and future products that are intended for, and marketed and labeled as, “Research Use Only,” or RUO, is uncertain if such products are used or could be used, even without our consent, for the diagnosis of acquisitions of businessesdisease. If the FDA or technologies.
As partother regulatory authorities assert that any of our strategyRUO products are subject to developregulatory clearance or approval, our business, financial condition, or results of operations could be adversely affected.

Doing business internationally creates operational and identify new products, services,financial risks for ourbusiness.

Conducting and technologies,launching operations on an international scale requires close coordination of activities across multiple jurisdictions and time zones and consumes significant management resources. If we fail to coordinate and manage these activities effectively, including the risks noted below, our business, financial condition, or results of operations could be adversely affected. We are focused on expanding our international operations in key markets. We have made,sales offices located internationally throughout Europe, the Asia-Pacific region, and mayBrazil, as well as manufacturing facilities in the United Kingdom and Singapore. During 2012, the majority of our sales to international customers were denominated in foreign currencies while the majority of our purchases of raw materials from international suppliers were denominated in U.S. dollars. Shipments to customers outside the United States comprised 51%, 50%, and 45% of our total revenue for fiscal years 2012, 2011, and 2010, respectively. We intend to continue to expand our international presence by selling to customers located outside of the United States and we expect the total amount of non-U.S. sales to continue to grow.

International sales entail a variety of risks, including:
longer payment cycles and difficulties in collecting accounts receivable outside of the United States;
longer sales cycles due to the volume of transactions taking place through public tenders;
currency exchange fluctuations;
challenges in staffing and managing foreign operations;
tariffs and other trade barriers;
unexpected changes in legislative or regulatory requirements of foreign countries into which we sell our products;
difficulties in obtaining export licenses or in overcoming other trade barriers and restrictions resulting in delivery delays; and
significant taxes or other burdens of complying with a variety of foreign laws.

Changes in the value of the relevant currencies may affect the cost of certain items required in our operations. Changes in currency exchange rates may also affect the relative prices at which we are able sell products in the same market. Our revenues from international customers may be negatively impacted as increases in the U.S. dollar relative to our international customers local currency could make acquisitionsour products more expensive, impacting our ability to compete. Our costs of technologies, products, or businesses. Acquisitions involvematerials from international suppliers may increase if in order to continue doing business with us they raise their prices as the value of the U.S. dollar decreases relative to their local currency. Foreign policies and actions regarding currency valuation could result in actions by the United States and other countries to offset the effects of such fluctuations. The recent global financial downturn

numerous risks20



has led to a high level of volatility in foreign currency exchange rates and operational, financial, and managerial challenges, including the following, anythat level of volatility may continue, which could adversely affect our business, financial condition, or results of operations:
• difficulties in integrating new operations, technologies, products, and personnel;
• lack of synergies or the inability to realize expected synergies and cost-savings;
• difficulties in managing geographically dispersed operations;
• underperformance of any acquired technology, product, or business relative to our expectations and the price we paid;
• negative near-term impacts on financial results after an acquisition, including acquisition-related earnings charges;
• the potential loss of key employees, customers, and strategic partners of acquired companies;
• claims by terminated employees and shareholders of acquired companies or other third parties related to the transaction;
• the issuance of dilutive securities, assumption or incurrence of additional debt obligations or expenses, or use of substantial portions of our cash;
• diversion of management’s attention and company resources from existing operations of the business;
• inconsistencies in standards, controls, procedures, and policies;
• the impairment of intangible assets as a result of technological advancements, orworse-than-expected performance of acquired companies; and
• assumption of, or exposure to, unknown contingent liabilities or liabilities that are difficult to identify or accurately quantify.
In addition, the successful integration of acquired businesses requires significant efforts and expense across all operational areas, including sales and marketing, research and development, manufacturing, finance, legal, and information technologies. We cannot assure you that any of the acquisitions we make will be successful or will be, or will remain, profitable. Our failure to successfully address the above risks may prevent us from achieving the anticipated benefits from any acquisition in a reasonable time frame, or at all.
The timing and extent of funding provided by the American Recovery and Reinvestment Act of 2009 (the Recovery Act) could adversely affect our business, financial condition, or results of operations.
The Recovery Act was enacted in February 2009 to provide stimulus to the U.S. economy in the wake of the economic downturn. As part of the Recovery Act legislation, over $10 billion in funding was provided to the National Institute of Health through September 2010 to support the advancement of scientific research. A portion of the stimulus funding may support the analysis of genetic variation and biological function and have a significant positive impact on our business. In the short-term, however, our customers may delay or reduce their purchases of our products as they wait to learn whether, and to what extent, they will receive stimulus funding. If our customers are unable to obtain stimulus money they may reduce their research and development budgets resulting in a decrease in demand for our products. In addition, it is unclear what will happen to demand for our products after the stimulus funds from the Recovery Act have been allocated and spent. A decline in demand will reduce our revenues, which would adversely affect our business, financial condition, or results of operations.

Although we believe our productstax estimates are reasonable, if the U.S. Internal Revenue Service or other taxing authority disagrees with the positions taken by the Company on its tax returns, we could have additional tax liability, including interest and services, or cost-containment efforts by governments and private organizations thatpenalties. If material, payment of such additional amounts upon final adjudication of any disputes could adversely affecthave a material impact on our business, financial condition, or results of operations. In addition, the liquidity of our investment portfolio could be impaired such as when more than $50 million of auction rate securities that we held for investment became illiquid in February 2008 because their scheduled auctions failed. Furthermore, as is the case for almost any other business, we face the following risks from a severe or prolonged economic downturn:operations and financial position.
• severely limited access to financing over an extended period of time, which may limit our ability to fund our growth strategy, could result in a need to delay capital expenditures, acquisitions, or research and development projects;
• losses from our investment portfolio or to a counterparty’s inability to fulfill its payment obligations;
• inability to refinance existing debt at competitive rates, reasonable terms, or sufficient amounts; and
• increased volatility or adverse movements in foreign currency exchange rates.

In addition, certain of our customers may face challenges gaining timely access to sufficient credit, which could result in an impairment of their ability to make timely payments to us. If that were to occur, our allowance for doubtful accounts and our days sales outstanding could increase. Additionally, these economic conditions may cause our smaller suppliers to be unable to supply in a timely manner sufficient quantities of customized components, which would impair our ability to manufacture on schedule and at commercially reasonable costs. Suppliers may also extend lead times, limit supplies, or increase prices due to capacity constraints or other factors.
Our continued growth is dependent on continuously developing and commercializing new products.
Our target markets are characterized by rapid technological change, evolving industry standards, changes in customer needs, existing and emerging competition, strong price competition, and frequent new product introductions. Accordingly, our continued growth depends on continuously developing and commercializing new products and services, including improving our existing products and services, in order to address evolving market requirements on a timely basis. If we fail to innovate or adequately invest in new technologies, our products and services will become dated and we could lose our competitive position in the markets that we serve as customers purchase new products offered by our competitors. We believe that successfully introducing new products and technologies in our target markets on a timely basis provides a significant competitive advantage because customers make an investment of time in selecting and learning to use a new product and may be reluctant to switch once that selection is made.
To the extent that we fail to introduce new and innovative products, or such products are not accepted in the market or suffer significant delays in development, we may lose market share to our competitors, which will be difficult or impossible to regain. An inability, for technological or other reasons, to successfully develop and introduce new products could reduce our growth rate or otherwise have an adverse effect on our business. In the past, we have experienced, and are likely to experience in the future, delays in the development and introduction of new products. We cannot assure you that we will keep pace with the rapid rate of change in our markets or that our new products will adequately meet the requirements of the marketplace, achieve market acceptance, or compete successfully with competing technologies. Some of the factors affecting market acceptance of new products and services include:
• availability, quality, and price relative to competing products and services;
• the functionality of new and existing products and services;
• the timing of introduction of the new product or service relative to competing products and services;
• scientists’ and customers’ opinions of the utility of the new product or service;
• citation of the new product or service in published research;


19


• regulatory trends and approvals; and
• general trends in life sciences research and applied markets.
We depend on third-party manufacturers and suppliers for components and materials used in our products, and if shipments from these manufacturers or suppliers are delayed or interrupted, or if the quality of the components or materials supplied do not meet our requirements, we may not be able to launch, manufacture, or ship our products in a timely manner, or at all.
The nature of our products requires customized components and materials that currently are available from a limited number of sources, and, in the case of some components and materials, from only a single source. If deliveries from these vendors are delayed or interrupted for any reason, or if we are otherwise unable to secure a sufficient supply, we may not be able to obtain these components or materials timely or in sufficient quantities or qualities, or at all, in order to meet demand for our products. We may need to enter into contractual relationships with manufacturers for commercial-scale production of some of our products, or develop these capabilities internally, and we cannot assure you that we will be able to do this on a timely basis, in sufficient quantities, or on commercially reasonable terms. Accordingly, we may not be able to establish or maintain reliable, high-volume manufacturing at commercially reasonable costs. In addition, the manufacture or shipment of our products may be delayed or interrupted if the quality of the components or materials supplied by our vendors does not meet our requirements. Any delay or interruption to our manufacturing process or in shipping our products could result in lost revenue, which would adversely affect our business, financial condition, or results of operations.
An inability to manage our growth or the expansion of our operations could adverselyaffect our business, financial condition, or results of operations.

Our business has grown rapidly, with total revenues increasing from $73.5 million for the year ended January 1, 2006 to $666.3 million$1.15 billion for the year ended January 3, 2010December 30, 2012 and with the number of employees increasing from 375 to 1,781approximately 2,400 during the same period. We expect to continue to experience rapid and substantial growth in order to achieve our operating plans. The rapidcontinued global expansion of our business and addition of new personnel may place a strain on our management and operational systems. Our ability to effectively manage our operations and growth requires us to continue to expend funds to enhance our operational, financial, and management controls, reporting systems, and procedures and to attract and retain sufficient numbers of talented employees on a global basis. If we are unable to scale up and implement improvements to our manufacturing process and control systems in an efficient or timely manner, or if we encounter deficiencies in existing systems and controls, then we will not be able to make available the products required to successfully commercialize our technology. Our future operating results will depend on the ability of our management to continue to implement and improve our research, product development, manufacturing, sales and marketing, and customer support programs, enhance our operational and financial control systems, expand, train, and manage our employee base, integrate acquired businesses, and effectively address new issues related to our growth as they arise. There can be no assurance that we will be able to manage our recent or any future expansion or acquisition successfully, and any inability to do so could adversely affect our business, financial condition, or results of operations.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals.
We are highly dependent on our management and scientific personnel, including Jay Flatley, our president and chief executive officer. The loss of their services could adversely impact our ability to achieve our business objectives. In addition, we will need to hire additional qualified personnel with expertise in molecular biology, chemistry, biological information processing, sales, marketing, and technical support. We compete for qualified management and scientific personnel with other life science companies, universities, and research institutions, particularly those focusing on genomics. Competition for these individuals, particularly in the San Diego and San Francisco area, is intense, and the turnover rate can be high. Failure to attract and retain management and scientific personnel would prevent us from pursuing collaborations or developing our


20


products or technologies. Additionally, integration of acquired companies and businesses can be disruptive, causing key employees of the acquired business to leave. Further, we use stock options and restricted stock to provide incentives for our key personnel to remain with us and to align their interests with those of the Company by building long-term stockholder value. If our stock price decreases, the value of these equity awards decreases and therefore reduces a key employee’s incentive to stay.
Doing business internationally creates operational and financial risks for our business.
Conducting and launching operations on an international scale requires close coordination of activities across multiple jurisdictions and time zones and consumes significant management resources. If we fail to coordinate and manage these activities effectively, including the risks noted below, our business, financial condition, or results of operations could be adversely affected. We are focused on expanding our international operations in key markets. We have sales offices located internationally throughout Europe and the Asia-Pacific region, as well as manufacturing facilities in the United Kingdom and Singapore. During 2009, the majority of our sales to international customers and purchases of raw materials from international suppliers were denominated in U.S. dollars. Shipments to customers outside the United States comprised 48%, 51%, and 43% of our total revenue for the years ended January 3, 2010, December 28, 2008, and December 30, 2007, respectively. We intend to continue to expand our international presence by selling to customers located outside of the United States and we expect the total amount ofnon-U.S. sales to continue to grow.
International sales entail a variety of risks, including:
• longer payment cycles and difficulties in collecting accounts receivable outside of the United States;
• currency exchange fluctuations;
• challenges in staffing and managing foreign operations;
• tariffs and other trade barriers;
• unexpected changes in legislative or regulatory requirements of foreign countries into which we sell our products;
• difficulties in obtaining export licenses or in overcoming other trade barriers and restrictions resulting in delivery delays; and
• significant taxes or other burdens of complying with a variety of foreign laws.
Changes in the value of the relevant currencies may affect the cost of certain items required in our operations. Changes in currency exchange rates may also affect the relative prices at which we are able sell products in the same market. Our revenues from international customers may be negatively impacted as increases in the U.S. dollar relative to our international customers local currency could make our products more expensive, impacting our ability to compete. Our costs of materials from international suppliers may increase if in order to continue doing business with us they raise their prices as the value of the U.S. dollar decreases relative to their local currency. Foreign policies and actions regarding currency valuation could result in actions by the United States and other countries to offset the effects of such fluctuations. The recent global financial downturn has led to a high level of volatility in foreign currency exchange rates and that level of volatility may continue, which could adversely affect our business, financial condition, or results of operations.
We are subject to risks related to taxation in multiple jurisdictions and the possible loss of the tax deduction on our outstanding convertible notes.
We are subject to income taxes in both the United States and numerous foreign jurisdictions. Significant judgments based on interpretations of existing tax laws or regulations are required in determining the provision for income taxes. Our effective income tax rate could be adversely affected by various factors, including, but not limited to, changes in the mix of earnings in tax jurisdictions with different statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in existing tax laws or tax rates,


21


changes in the level of non-deductible expenses (including share-based compensation), changes in our future levels of research and development spending, mergers and acquisitions, or the result of examinations by various tax authorities.
In addition, we could lose some or all of the tax deduction for interest expense associated with our $400 million aggregate principal amount of convertible notes due in 2014 if these notes are not subject to the special Treasury Regulations governing contingent payment debt instruments, the notes are converted, or we invest in non-taxable investments.
Any inability to effectively protect our proprietary technologies could harm our competitive position.
Our success depends to a large extent on our ability to develop proprietary products and technologies and to obtain patents and maintain adequate protection of our intellectual property in the United States and other countries. If we do not protect our intellectual property adequately, competitors may be able to use our technologies and thereby erode our competitive advantage. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant challenges in establishing and enforcing their proprietary rights outside of the United States. These challenges can be caused by the absence of rules and methods for the establishment and enforcement of intellectual property rights outside of the United States.
The patent positions of companies developing tools for the life sciences, agricultural, and pharmaceutical industries, including our patent position, generally are uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. In addition, patent applications in the United States may be maintained in secrecy until patents issue, and publication of discoveries in the scientific or patent literature tend to lag behind actual discoveries by several months. We intend to apply for patents covering our technologies and products as we deem appropriate. However, our patent applications may be challenged and may not result in issued patents or may be invalidated or narrowed in scope after they are issued. Questions as to inventorship or ownership may also arise. Any finding that our patents or applications are unenforceable could harm our ability to prevent others from practicing the related technology, and a finding that others have inventorship or ownership rights to our patents and applications could require us to obtain certain rights to practice related technologies, which may not be available on favorable terms, if at all. Furthermore, as issued patents expire, we may lose some competitive advantage as others develop competing products, and, as a result, we may lose revenue.
In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products. There is also the risk that others may independently develop similar or alternative technologies or design around our patented technologies. Also, our patents may fail to provide us with any competitive advantage. We may need to initiate lawsuits to protect or enforce our patents, or litigate against third party claims, which would be expensive, and, if we lose, may cause us to lose some of our intellectual property rights and reduce our ability to compete in the marketplace. Furthermore, these lawsuits may divert the attention of our management and technical personnel.
We also rely upon trade secrets and proprietary know-how protection for our confidential and proprietary information, and we have taken security measures to protect this information. These measures, however, may not provide adequate protection for our trade secrets, know-how, or other confidential information. Among other things, we seek to protect our trade secrets and confidential information by entering into confidentiality agreements with employees, collaborators, and consultants. There can be no assurance that any confidentiality agreements that we have with our employees, collaborators, and consultants will provide meaningful protection for our trade secrets and confidential information or will provide adequate remedies in the event of unauthorized use or disclosure of such information. Accordingly, there also can be no assurance that our trade secrets will not otherwise become known or be independently developed by competitors.


22


Litigation, other proceedings, or third party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products or services.
Our success depends, in part, on our non-infringement of the patents or proprietary rights of third parties. Third parties have asserted and may in the future assert that we are employing their proprietary technology without authorization. As we enter new markets, we expect that competitors will likely claim that our products infringe their intellectual property rights as part of a business strategy to impede our successful entry into those markets. In addition, third parties may have obtained and may in the future obtain patents allowing them to claim that the use of our technologies infringes these patents. We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against any of these claims. Any adverse ruling or perception of an adverse ruling in defending ourselves against these claims could have an adverse impact on our stock price, which may be disproportionate to the actual import of the ruling itself. Furthermore, parties making claims against us may be able to obtain injunctive or other relief, which effectively could block our ability to develop further, commercialize, or sell products, and could result in the award of substantial damages against us. In the event of a successful infringement claim against us, we may be required to pay damages and obtain one or more licenses from third parties, or be prohibited from selling certain products. In addition, we may be unable to obtain these licenses at a reasonable cost, if at all. We could therefore incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins. In addition, we could encounter delays in product introductions while we attempt to develop alternative methods or products. Defense of any lawsuit or failure to obtain any of these licenses on favorable terms could prevent us from commercializing products, and the prohibition of sale of any of our products could adversely affect our ability to grow or maintain profitability.
Our products, if used for the diagnosis of disease, could be subject to government regulation, and the regulatory approval and maintenance process for such products may be expensive, time-consuming, and uncertain both in timing and in outcome.
Our products are not currently subject to FDA clearance or approval if they are not intended to be used for the diagnosis of disease. However, as we expand our product line to encompass products that are intended to be used for the diagnosis of disease, certain of our products are likely to become subject to regulation by the FDA, or comparable agencies of other countries, including requirements for regulatory approval of such products before they can be marketed. Such regulatory approval processes or clearances may be expensive, time-consuming, and uncertain, and our failure to obtain or comply with such approvals and clearances could have an adverse effect on our business, financial condition, or operating results. In addition, changes to the current regulatory framework, including the imposition of 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 or maintain FDA or comparable regulatory approval of our products, if required.
Molecular diagnostic products, in particular, depending on their intended use, may be regulated as medical devices by the FDA and comparable agencies of other countries and may require either receiving clearance from the FDA following a pre-market notification process or premarket approval from the FDA, in each case prior to marketing. Obtaining the requisite regulatory approvals can be expensive and may involve considerable delay. If we fail to obtain, or experience significant delays in obtaining, regulatory approvals for molecular diagnostic products that we develop, we may not be able to launch or successfully commercialize such products in a timely manner, or at all.
In addition, the regulatory approval or clearance process required to manufacture, market, and sell our existing and future products that are intended for, and marketed and labeled as, “Research Use Only,” or RUO, is uncertain if such products are used or could be used, even without our consent, for the diagnosis of disease. If the FDA or other regulatory authorities assert that any of our RUO products are subject to regulatory clearance or approval, our business, financial condition, or results of operations could be adversely affected.


23


Our operating results may vary significantly from period to period, and we may not beable to sustain operating profitability.

Our revenue is subject to fluctuations due to the timing of sales of high-value products and services, the effects of new product launches and related promotions, the timing and availability of our customers’ funding, the impact of seasonal spending patterns, the timing and size of research projects our customers perform, the timing of our customers’ funding, changes in overall spending levels in the life sciences industry, and other unpredictable factors that may affect customer ordering patterns. Given the difficulty in predicting the timing and magnitude of sales for our products and services, we may experiencequarter-to-quarter fluctuations in revenue resulting in the potential for a sequential decline in quarterly revenue. While we anticipate future growth, there is some uncertainty as to the timing of revenue recognition on a quarterly basis. This is because a substantial portion of our quarterly revenue is typically recognized in the last month of a quarter and because the pattern for revenue generation during that month is normally not linear, with a concentration of orders in the final week of the quarter. In light of that, our revenue cut-off and recognition procedures, together with our manufacturing and shipping operations, may experience increased pressure and demand during the time period shortly before the end of a fiscal quarter.

A large portion of our expenses isare relatively fixed, including expenses for facilities, equipment, and personnel. In addition, we expect operating expenses to continue to increase significantly in absolute dollars, and we expect that our research and development and selling and marketing expenses will increase at a higher rate in the future as a result of the development and launch of new products. Accordingly, our ability to sustain profitability will depend, in part, on the rate of growth, if any, of our revenue and on the level of our expenses, and if revenue does not grow as anticipated, we may not be able to maintain annual or quarterly profitability. Any significant delays in the commercial launch of our products, unfavorable sales trends in our existing product lines, or impacts from the other factors mentioned above, could adversely affect our future revenue growth or cause a sequential decline in quarterly revenue. In addition, non-cash stock-basedshare-based compensation expense and expenses related to prior and future acquisitions are also likely to continue to adversely affect our future profitability. Due to the

21



possibility of significant fluctuations in our revenue and expenses, particularly from quarter to quarter, we believe that quarterly comparisons of our operating results are not a good indication of our future performance. If our operating results fluctuate or do not meet the expectations of stock market analysts and investors, our stock price could decline.

From time to time, we receive large orders that have a significant effect on our operating results in the period in which the order is recognized as revenue. The timing of such orders is difficult to predict, and the timing of revenue recognition from such orders may affect period to period changes in net sales. As a result, our operating results could vary materially from quarter to quarter based on the receipt of such orders and their ultimate recognition as revenue.

Changes in accounting standards and subjective assumptions, estimates, and judgmentsby management related to complex accounting matters could significantly affect ourfinancial results or financial condition.

Generally accepted accounting principles and related accounting pronouncements, implementation guidelines, and interpretations with regard to a wide range of matters that are relevant to our business, such as revenue recognition, asset impairment and fair value determinations, inventories, business combinations and intangible asset valuations, and litigation, are highly complex and involve many subjective assumptions, estimates, and judgments. Changes in these rules or their interpretation or changes in underlying assumptions, estimates, or judgments could significantly change our reported or expected financial performance or financial condition. In addition, the timing of large orders can have a significant effect on our business and operating results from quarter to quarter.

Ethical, legal, and social concerns related to the use of genetic information couldreduce demand for our products or services.

Genetic testing has raisedOur products may be used to provide genetic information about humans, agricultural crops, and other living organisms. The information obtained from our products could be used in a variety of applications, which may have underlying ethical, legal, and social issuesconcerns regarding privacy and the appropriate uses of the resulting information.information, including preimplantation genetic screening of embryos, prenatal genetic testing, genetic engineering or modification of agricultural products, or testing genetic predisposition for certain medical conditions, particularly for those that have no known cure. Governmental authorities could, for social or other purposes, call for limits on or


24


regulation of the use of genetic testing or prohibit testing for genetic predisposition to certain conditions, particularly for those that have no known cure. Similarly, such concerns may lead individuals to refuse to use genetics tests even if permissible. These and other ethical, legal, and social concerns about genetic testing may limit market acceptance of our technology for certain applications or reduce the potential markets for our technology, either of which could have an adverse effect on our business, financial condition, or results of operations.

Our strategic equity investments may result in losses.

We periodically make strategic equity investments in various public and private companies with businesses or technologies that may complement our business. The market values of these strategic equity investments may fluctuate due to market conditions and other conditions over which we have no control. Other-than-temporary declines in the market price and valuations of the securities that we hold in other companies would require us to record losses in proportion to our ownership interest. This could result in future charges to our earnings. It is uncertain whether or not we will realize any long-term benefits associated with these strategic investments.

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information, and that of our customers, and personally identifiable information of our customers and employees, in our data centers and on our networks. The secure maintenance of this information is important to our operations and business strategy. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost, or stolen. Any such access, disclosure, or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, and damage to our reputation.

Conversion of our outstanding convertible notes may result in losses.

As of December 30, 2012, we had $40 million aggregate principal amount of convertible notes due 2014 and $920 million aggregate principal amount of convertible notes due 2016 outstanding. The notes are convertible into cash, and if applicable, shares of our common stock under certain circumstances, including trading price conditions related to our common

22



stock. If the trading price of our common stock remains significantly above the conversion price of $21.83 per share with respect to convertible notes due 2014 and $83.55 with respect to convertible notes due 2016, we expect that the noteholders will elect to convert the applicable notes. Upon conversion, we are required to record a gain or loss for the difference between the fair value of the notes to be extinguished and their corresponding net carrying value. The fair value of the notes to be extinguished depends on our current incremental borrowing rate. The net carrying value of our notes has an implicit interest rate of 8.3% with respect to convertible notes due 2014 and 4.5% with respect to convertible notes due 2016. If our incremental borrowing rate at the time of conversion is lower than the implied interest rate of the notes, we will record a loss in our consolidated statement of income during the period in which the notes are converted.

Our Certificate of Incorporation and Bylaws include anti-takeover provisions that may make it difficult for another company to acquire control of us or limit the price investors might be willing to pay for our stock.

Certain provisions of our Certificate of Incorporation and Bylaws could delay the removal of incumbent directors and could make it more difficult to successfully complete a merger, tender offer, or proxy contest involving us. These provisions include our Preferred Shares Rights Agreement, commonly known as a “poison pill” and provisions in our Certificate of Incorporation that give our Board the ability to issue preferred stock and determine the rights and designations of the preferred stock at any time without stockholder approval. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock. In addition, the staggered terms of our board of directors could have the effect of delaying or deferring a change in control.

In addition, certain provisions of the Delaware General Corporation Law (“DGCL”), including Section 203 of the DGCL, may have the effect of delaying or preventing changes in the control or management of Illumina. Section 203 of the DGCL provides, with certain exceptions, for waiting periods applicable to business combinations with stockholders owning at least 15% and less than 85% of the voting stock (exclusive of stock held by directors, officers, and employee plans) of a company.

The above factors may have the effect of deterring hostile takeovers or otherwise delaying or preventing changes in the control or management of Illumina, including transactions in which our stockholders might otherwise receive a premium over the fair market value of our common stock.

ItemITEM 3.Legal Proceedings.

From time to time, weWe are party to litigationinvolved in various lawsuits and other legal proceedingsclaims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and incidentalcontractual matters. In connection with these matters, we assess, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. We recorded a legal contingency loss of $3.0 million in aggregate within cost of product revenue in 2012. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures. The amount of ultimate loss may differ from these estimates. Each matter presents its own unique circumstances, and prior litigation does not necessarily provide a reliable basis on which to predict the outcome, or range of outcomes, in any individual proceeding. Because of the uncertainties related to the conduct,occurrence, amount, and range of our business. Whileloss on any pending litigation or claim, we are currently unable to predict their ultimate outcome, and, with respect to any pending litigation or claim where no liability has been accrued, to make a meaningful estimate of the resultsreasonably possible loss or range of loss that could result from an unfavorable outcome. In the event that opposing litigants in outstanding litigations or claims ultimately succeed at trial and any subsequent appeals on their claims, any potential loss or charges in excess of any litigationestablished accruals, individually or other legal proceedings are uncertain, management does not believein the ultimate resolution of any pending legal matters is likely toaggregate, could have a material adverse effect on our business, financial position orcondition, results of operations.operations, and/or cash flows in the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods.
On November 24, 2010, Syntrix Biosystems, Inc. filed suit against us in the United States District Court for the Western District of Washington at Tacoma (Case No. C10-5870-BHS) alleging that we willfully infringed U.S. Patent No. 6,951,682 by selling our BeadChip array products, and that we misappropriated Syntrix’s trade secrets. Fact and expert discovery is complete in the case. In November and December 2012, we filed motions for summary judgment that the patent is not infringed and is invalid, and that Syntrix’s trade secrets claims are barred by various statutes of limitation. Syntrix filed a motion for summary judgment that the patent is valid. On January 30, 2013, the court granted our motion for summary judgment on Syntrix’s trade secret claims, and dismissed those claims from the case. The court denied Syntrix’s motion for summary judgment on validity, and denied our motion for summary judgment for non-infringement and invalidity. A trial is scheduled to begin on February 26, 2013.
We have thoroughly investigated Syntrix’s claims and believe the claims are without merit. While we believe there is no legal basis for the alleged liability, we cannot estimate the possible loss or range of possible loss as there are significant legal and factual issues to be resolved. For example, each party has filed motions seeking to exclude portions of the other party’s expert testimony and to preclude the other party from introducing certain other evidence at trial. In addition to post-trial briefing, the parties would likely engage in appellate motion practice, the result of which is also unpredictable and could significantly affect the outcome of the case.

In addition to the following notes, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”Operations,” and Item 8, “Financial Statements and Supplementary Data”Data,” for further information regarding our consolidated results of operations and financial position for periods reported therein and for known factors that will impact comparability of future results.

(1)Adjusted for required retroactive adoption
During 2011, we issued $920.0 million principal amount of authoritative accounting guidance for0.25% Convertible Senior Notes due 2016, which was classified as long-term liability as of December 30, 2012 and January 1, 2012. In February 2007, we issued $400.0 million principal amount of 0.625% Convertible Senior Notes due 2014. Due to the 0.625% Convertible Senior Notes due 2014 being convertible debt instruments that may be settledduring the fiscal years ended December 30, 2012, January 2, 2011, January 3, 2010, and December 28, 2008, we classified the outstanding principal amount of these notes as current in cash upon conversion effective December 29, 2008.our consolidated balance sheet in the respective periods. As of January 1, 2012, the outstanding principal amount of the 0.625% Convertible Senior Notes was not convertible and was therefore reclassified to long-term liability. See Note 7 ofnote “7. Convertible Senior Notes” in Part II, Item 8, Notes to Consolidated Financial Statements, for further information.
(2)The consolidated financial statements include results of operations of acquired companies commencing on their respective acquisition dates. We completed acquisitions of Avantome, Inc., Solexa, Inc., and Cyvera Corporation in August 2008, January 2007 and April 2005, respectively. As part of the accounting for these acquisitions, we recorded charges to write-off acquired in-process research and development, or IPR&D, of $11.3 million, $24.7 million, $303.4 million and $15.8 million during
For the fiscal years ended December 30, 2012, January 1, 2012, January 2, 2011, January 3, 2010, and December 28, 2008 December 30, 2007, we repurchased 1.9 million, 9.2 million, 0.8 million, 6.1 million, and January 1, 2006,3.1 million shares, respectively, of common stock for $82.5 million, $570.3 million, $44.0 million, $175.1 million, and $70.8 million, respectively. See Note 1 ofnote “10. Stockholders’ Equity” in Part II, Item 8, Notes to Consolidated Financial Statements for further information.Statements.

(3)On January 2, 2006 we adopted authoritative guidance related to share-based payments using the modified prospective transition method. Because we elected to use the modified prospective transition method, results for prior periods have not been restated to include share-based compensation expense. See Note 1 and Note 9 of Notes to Consolidated Financial Statements for further information.
(4)For the year ended December 30, 2007, we recorded a $54.0 million charge for the settlement of our litigation with Affymetrix. In January 2008, we paid $90.0 million related to the Affymetrix settlement. See Note 4 of Notes to Consolidated Financial Statements.
(5)In August 2008, a total of 8,050,000 shares were sold to the public at a public offering price of $43.75 per share, raising net proceeds to us of $342.7 million. See Note 9 of Notes to Consolidated Financial Statements.
(6)For the years ended January 3, 2010, December 28, 2008 and December 30, 2007, we repurchased 6.1 million, 3.1 million and 14.8 million shares, respectively, of common stock for $175.1 million, $70.8 million and $251.6 million, respectively. See Note 9 of Notes to Consolidated Financial Statements.
(7)In February 2007, we issued $400.0 million principal amount of 0.625% Convertible Senior Notes due 2014. During the third quarter of 2008, the conditions to convertibility were satisfied resulting in a change in the classification of the principal amount of the notes from long-term to current. See Note 7 of Notes to Consolidated Financial Statements for further information.

To further enhance our genetic analysis workflows, in 2011 we are the only company with genome-scale technologyacquired Epicentre Technologies Corporation (Epicentre), a leading provider of nucleic acid sample preparation reagents and specialty enzymes for sequencing genotyping, and gene expression — the three cornerstonesmicroarray applications. In 2010, through our acquisition of modern genetic analysis.
Our tools provide researchers around the world with the performance, throughput, cost effectiveness, and flexibility necessaryHelixis, Inc., we expanded our portfolio to determine and analyze the billions of bits of genetic information needed to extract valuable medical information from advances in genomics and proteomics. We believe this information will enable researchers to correlate genetic variation and biological function, which will enhance drug discovery and clinical research, allow diseases to be detected earlier, and permit better choices of drugs for individual patients.
During the first quarter of 2008, we reorganized our operating structure into a newly created Life Sciences Business Unit, which includes all products and services that are primarily related to the research market, namely those based on our sequencing, BeadArray and Veracode technologies. We also created a Diagnostics Business Unit to focus on the emerging opportunity in molecular diagnostics. For the year ended January 3, 2010, we had limited activity related to the Diagnostics Business Unit and operating results were reported on an aggregate basis to the chief operating decision maker, the chief executive officer. Accordingly, we operated ininclude real-time polymerase chain reaction (PCR), one segment for the year ended January 3, 2010. We will begin reporting in two segments once revenues, operating profit or loss, or assets of the Diagnostics Business Unit exceed 10% of the consolidated amounts.most widely used technologies in life sciences. Our Eco Real-Time PCR System provides researchers with an affordable, full-featured system to perform targeted validation studies.
Our analysis presented below is organized to provide the information we believe will be useful for understanding the relevant trends going forward. However, this discussion should be read in conjunction with our consolidated financial statements and the notes thereto in Item 15 of this report.
Business Trends and Outlook

Our financial results have been, and will continue to be, impacted by several significant trends, which are described below:
Next Generation Sequencing
Strong demand for next generation sequencing applications continues to drive both sequencing instrument and consumable sales. In 2009 we made advances to our sequencing technology, including enhanced chemistry, algorithms, and hardware which substantially improved accuracy, read length, data density, and ease of use. The combination of these advances increased the output and decreased the cost of sequencing and expanded the number of applications that researchers can perform on our sequencing systems. In early 2010 we expect to begin customer shipments of our recently announced HiSeq 2000 next generation sequencing instrument, which we believe will allow customers to sequence whole human genomes for less than $10,000 in reagent costs. We anticipate our revenue for 2010 will have higher growth in the second half of the year


29


compared to the first half due to the timing of the manufacturingscale-up of the HiSeq 2000 and other significant product launches scheduled for later in the year. We believe that as the cost of next generation sequencing continues to decline, the number of samples available for sequencing will significantly increase.
Genome Wide Association Studies (GWAS)
We experienced a slowdown in the sales of our microarray products during 2009 that was largely attributable to researchers reducing or suspending the initiation of new studies as they waited for rare variant content emerging from the 1000 Genomes Project, an international research effort launched in 2008 to establish the most detailed catalog of human genetic variation. Despite advances in sequencing technology, we believe microarrays remain a cheaper, faster and materially more accurate technology for use when genetic content is known. The information content of specific microarrays is fixed and reproducible; as such, specific microarrays provide repeatable, standardized assays for certain subsets of bases within the overall genome. During 2010, as part of our previously announced GWAS roadmap, we plan to launch arrays that will feature millions of more markers per BeadChip and new rare variant content from the 1000 Genomes Project. As these arrays become available, we believe activity in the microarray market will increase relative to 2009.
American Recovery and Reinvestment Act of 2009 (the Recovery Act)
The Recovery Act was enacted in February 2009 to provide stimulus to the U.S. economy in the wake of the economic downturn. As part of the Recovery Act legislation, over $10 billion in funding was provided to the National Institute of Health (NIH) through September 2010 to support the advancement of scientific research. In the second and third quarters of 2009 we experienced negative unintended consequences of the Recovery Act as customers delayed orders while they waited to receive stimulus funds. During the fourth quarter of 2009, we believe we saw an increase in the distribution of Recovery Act funds and received an estimated $16 million in orders directly related to Recovery Act grants. We believe a significant portion of Recovery Act awards may be distributed in 2010, which may create a pipeline of opportunity in the upcoming year.
Life Science Research Funding Across Regional Markets
We have developed a broad sales and distribution network with a sales presence in more than 40 countries. Our financial results will continue to be impacted by significant regional trends in life science research funding as described below:
• United States.  A significant increase to the NIH budget in addition to Recovery Act stimulus funds has made for a strong funding environment in the United States that we expect to continue into 2010.
• Asia-Pacific.  Strong funding in China was partially offset by a funding decrease in Japan due to a change in government that resulted in the suspension of supplemental life science research funding during the second and third quarters of 2009. During the fourth quarter of 2009, we saw an increase in activity in the Japanese market as funds began to be released, which we expect to continue into 2010.
• Europe.  Central and southern European markets had a strong year driven by the establishment and expansion of genome centers. However, there was a decrease in funding in northern European countries, primarily due to reduced institutional funding in areas like the United Kingdom and the financial crisis in Iceland. We saw some positive signs during the fourth quarter of 2009 in Northern Europe, and, although we expect funding to stabilize, we do not expect a material increase in activity in this region in 2010.
Cost of Revenue
Our cost of revenue as a percentage of revenue declined during 2009 due to cost efficiencies in our manufacturing process and an improved mix of sequencing consumables driven by growth in the installed base of our sequencing systems. We expect changes in our product mix to continue to affect our cost of revenue as a percentage of revenue, particularly in the latter half of the year. We anticipate cost of revenue as a


30


percentage of revenue to be lower in the first half of the year and then increase as the mix shifts to newer products and the effects of our trade-in promotions associated with the launch of the HiSeq 2000 are realized. Additionally, we expect price competition to continue in our market causing added variability in our cost of revenue as a percentage of revenue on a quarterly and annual basis.
Operating Expense
We expect to incur additional operating costs to support the expected growth in our business. As a result of revenues growing faster in the second half of 2010, we expect operating expenses as a percentage of revenue to be higher in the first half of the year compared with the second half. We believe a substantial investment in research and development is essential to remaining competitive and expanding into additional markets. Accordingly, we expect our research and development expenses to increase in absolute dollars as we expand our product base. Selling, general and administrative expenses are also expected to increase in absolute dollars as we continue to expand our staff and add sales and marketing infrastructure.
below. While these trends are important to understanding and evaluating our financial results, this discussion should be read in conjunction with our consolidated financial statements and the notes thereto in Item 1, Part I of this report, and the other transactions, events, and trends discussed in “Risk Factors” in Item 1A, Part I of this report may also materiallyreport.

Funding Environment
There remains significant uncertainty concerning government and academic research funding worldwide as governments in the United States and Europe, in particular, focus on reducing fiscal deficits while at the same time confronting slow economic growth. We believe this uncertainty will continue in 2013, which could lead to purchasing delays and could negatively impact our businessbusiness.

While many of our customers receive funding from government agencies to purchase our products or services, we are increasingly less dependent on government funding. In fiscal 2012, approximately 30% of our total revenue came from commercial customers who are not reliant on government agencies for funding, and it is our strategy to diversify our customer base to increase further the portion of our revenue from commercial customers over time. However, we estimate that approximately one-third of our total revenue continues to be derived, directly or indirectly, from funding provided by the U.S. National Institute of Health (NIH). In fiscal 2012, the NIH budget increased 1% as compared to fiscal 2011 levels. NIH funding for the first quarter of 2013 will be subject to the continuing resolution that was signed into law by President Obama and funds the NIH at 90% of budget. The significance and timing of any reductions to the NIH budget from March 2013 may be significantly impacted by the sequestration provisions of the Budget Control Act of 2011 and by whether these provisions remain in effect. In addition, the U.S. Department of Health and Human Services (HHS), of which the NIH is a part, has the ability to reallocate funds within its budget to spare the NIH from the full effect of HHS budget reductions.  We further believe that allocations within the NIH budget will continue to favor genetic analysis tools generally and, in particular, research programs that utilize next-generation sequencing.

Next-Generation Sequencing

Next-generation sequencing has become a core technology for modern life science research and is increasingly being used in the applied, molecular diagnostics, and translational markets. Over the next several years, expansion of the sequencing market, including an increase in the number of samples available and enhancements in our product portfolio will continue to drive demand for our next-generation sequencing technologies. Our sequencing instrument installed base continued to expand in 2012. As a result, we believe that our sequencing consumable revenue will continue to grow in future periods.

Our sequencing instrument portfolio primarily includes the HiSeq product family and MiSeq. We began full commercial shipments in the fourth quarter of 2012 of our previously announced HiSeq 2500 sequencing system, which allows customers to sequence an entire human genome in approximately a day. Our MiSeq sequencing system is a low-cost personal sequencing system that we believe will provide individual researchers a platform with rapid turnaround time, high accuracy, and streamlined workflow. We believe our MiSeq systems will continue to be a competitive offering in the lower throughput sequencing market and help us expand our presence in this emerging market segment.

MicroArrays

As a complement to next-generation sequencing, we believe microarrays offer a less expensive, faster, and highly accurate technology for use when genetic content is already known. The information content of microarrays is fixed and reproducible. As such, microarrays provide repeatable, standardized assays for certain subsets of nucleotide bases within the overall genome. As the cost of sequencing continues to decrease, we believe that life science researchers will migrate certain whole genome array studies to sequencing over the next few years; however, we expect this decline to be offset by demand from customers in applied and translational markets.

Financial Overview

Financial highlights for 2012 include the following:
Net revenue increased by 9% during 2012 compared to 2011. The increase in revenue was primarily driven by an increase in consumable sales and instrument service contract revenue as our installed base continued to expand in 2012. We believe our revenue will continue to grow in 2013.
Gross profit as a percentage of revenue (gross margin) was 67.4% in 2012, an increase from 67.2% in 2011. Gross margin improved in 2012 due in large part to the shift in sales mix from instruments to consumables, which have a higher gross margin than instruments. We believe our gross margin in future periods will depend on several factors, including market conditions that may impact our pricing power, product mix changes between consumable, instrument, and service sales, product mix changes between established products and new products in new markets, our cost structure for manufacturing operations, and financial results.our ability to create innovative and high premium products that meet or stimulate customer demand.


31


Income from operations increased slightly by $1.3 million in 2012 compared to 2011. This was a result of higher gross profit, which was driven by increased revenue, being mostly offset by higher operating expenses. In 2012, our research and development expenses increased by $34.1 million and our selling, general and administrative expenses increased by $24.1 million as we continue to grow our business. We anticipate that the dollar amount of these expenses will increase as we continue to invest in our technology, people, and infrastructure to support our growth.
In 2012, we completed the relocation of our headquarters that started in 2011 and incurred $26.3 million in headquarter relocation expense, which primarily included a cease-use loss upon vacating our prior headquarters, double rent expense during the transition to the new facility, and the accretion of interest expense on the related lease exit liability. We do not expect to incur significant additional headquarter relocation expense other than the accretion of interest expense on lease exit liability.
In 2012, we also incurred $23.1 million in expenses associated with the unsolicited tender offer for shares of our common stock commenced by CKH Acquisition Corp. and Roche Holding Ltd. (together, “Roche”) in early 2012. We anticipate incurring additional advisory expenses through mid-2013.
Our effective tax rate was 32.1% in 2012, as compared to 34.9% in 2011. The provision for income taxes is dependent on the mix of earnings in tax jurisdictions with different statutory tax rates and the other factors discussed in the risk factor “We are subject to risks related to taxation in multiple jurisdictions” in Item 1A of this report. For 2013 and beyond, we anticipate the provision for income taxes to increase in absolute dollars but the effective tax rate to trend lower than the U.S. federal statutory rate as the portion of our earnings subject to lower statutory tax rates increases.
The American Taxpayer Relief Act of 2012, which was signed into law on January 2, 2013, included the retroactive reinstatement of the federal research and development credit from January 1, 2012, through December 31, 2013. Our provision for income taxes for the year ended December 30, 2012, did not include the impact of the federal research credit generated in 2012 since the law was enacted subsequent to our reporting period. Had the legislation been enacted in 2012, the provision for income taxes for the year ended December 30, 2012, would have been reduced by approximately $2.0 million. Our provision for income taxes in the first quarter of 2013 will include the tax benefit as a result of the retroactive reinstatement of the federal research credit for 2012.
We ended 2012 with cash, cash equivalents, and short-term investments totaling $1.35 billion.

2012 Compared to 2011

Consumables revenue increased$133.5 million, or 22%, to $729.3 million in 2012 compared to $595.8 million in 2011. The increase was primarily attributable to increased sales of sequencing consumables, driven by higher consumable sales per HiSeq instrument and the growth in both the HiSeq and MiSeq installed base.

Instrument revenue decreased$58.8 million, or 16%, to $314.3 million in 2012 compared to $373.1 million in 2011, driven by a decrease in HiSeq shipments, partially offset by a full year of MiSeq shipments in 2012 as compared to less than two quarters of shipments in 2011.

Revenue in 2011 reflects the impact of discounts provided to customers under our Genome Analyzer trade-in program. The estimated incremental sales incentive provided under this trade-in program was approximately $11.1 million, based on the total discount provided from list price in excess of our average discount on HiSeq 2000 sales during the period. The Genome Analyzer trade-in program was completed in Q4 2011. See “Revenue Recognition” in note “1. Summary of Significant Accounting Policies” in Part II, Item 8, of this Form 10-K for additional information on the Genome Analyzer trade-in program.

The increase in service and other revenue in 2012 compared to 2011 was driven by an increase in our instrument service contract revenue as a result of our growing installed base as well as an increase in our genotyping and sequencing service revenue.

2011 Compared to 2010

Consumables revenue increased $57.6$90.8 million, or 17%18%, to $391.3$595.8 million for the year ended January 3, 2010in 2011 compared to $333.7$505.0 million for the year ended December 28, 2008. Microarray consumable revenue,in 2010. The increase was primarily attributable to increased sales of sequencing consumables, which constitutedaccounted for more than half of our consumableconsumables revenue declined $11.4 million, or 4%, primarily attributable to lower sales of whole-genome genotyping arrays partially offset by growth in focused content arrays. The decline was driven by customers delaying the start of new GWAS in anticipation of new and rare variant content from the 1000 Genome Project, order delays directly related to stimulus funding under the Recovery Act and the impact of reduced foundation funding at a few key customers. Sales volume for our Infinium BeadChip product lines, which constitute a majority of our microarray consumable sales, was relatively flat on a sample basis during 2009 compared to 2008. The average selling price per sample, however, declined due to a change in product mix attributable to growth in the sales of our focused content arrays coupled with lower sales of whole-genome genotyping arrays and an increase in the average number of samples per BeadChip.
Revenue from sequencing consumables increased $68.9 million, or 144%,2011, driven by growth in the installed base of our sequencing systems, partially offset by a decrease in the consumable revenue per sequencing instrument.

Instrument revenue increased $48.5 million, or 15%, to $373.1 million in 2011 compared to $324.6 million in 2010. The increase was primarily attributable to the launch of MiSeq in the third quarter of 2011 and higher HiSeq revenue primarily driven by increased average selling price following completion of the Genome Analyzer systemstrade-in program during the first half of 2011. These increases in instrument revenue were partially offset by a decrease in sales of our Genome Analyzer from 2010 to 2011, as our Genome Analyzer customers upgraded to HiSeq 2000.

Revenue from HiSeq 2000 sales in 2011 and 2010 was impacted by discounts provided to customers under our Genome Analyzer trade-in program. The estimated incremental sales incentive provided under this trade-in program was approximately $11.1 million and $47.8 million in 2011 and 2010, respectively. See “Revenue Recognition” in note “1. Organization and Summary of Significant Accounting Policies” in Part II, Item 8, of this Form 10-K for additional information on the progression of customer labs ramping to production scale. Genome Analyzer trade-in program.

The increase in service and other revenue in 2011 compared to 2010 was primarily driven by an increase in our instrument service contract revenue resulting from our expanded installed base and an increase in sequencing services.

Gross margin increased in 2011 compared to 2010. During the period, the gross margin of our larger sequencing customers began experiencing higher thaninstrument sales improved, primarily driven by an increase in average error ratesselling price per instrument as our Genome Analyzer trade-in program was substantially completed in the first half of 2011.

2012 Compared to 2011

Research and development expense increased by $34.1 million, or 17%, in 2012 from the sale of instruments increased $40.0 million, or 22%, to $225.7 million for the year ended January 3, 2010 compared to $185.7 million for the year ended December 28, 20082011, primarily due to a $56.4$21.4 million or 43%, impairment loss recognized for IPR&D recorded as a result of a prior acquisition and increased personnel expenses as we continue to increase our investment in projects to develop and commercialize new products. In addition, we incurred increased facilities expenses in 2012 as the rental fees for our current headquarters are higher than our prior facility.

Selling, general and administrative expense increased by $24.1 million in 2012 from 2011. The increase is primarily driven by a $15.8 million increase in sales of our sequencing systems. During 2009 as compared to 2008 both units soldpersonnel expenses associated with increased headcount, and average selling prices increased for our Genome Analyzer systems, which constitute a majority of sequencing instrument revenue. The$9.5 million increase in units sold was driven by increased demand for next generation sequencinglegal and oursequencing-by-synthesis technology. The increaseother consulting fees. Personnel expenses included salaries, share-based compensation, and benefits. These increases in average selling prices was attributable to the product transition from the Genome Analyzer I to the Genome Analyzer II in the second quarter of 2008 and technological improvements leading to the launch of the Genome Analyzer IIx in the second quarter of 2009. The increase in sequencing instrument revenue wasexpense were partially offset by a $16.4$2.3 million or 30%, decrease in the sales of our microarray systems, which declined primarily due to customers delaying the start of new GWASbad debt expense, as certain customer bankruptcies impacted us in anticipation of new and rare variant content from the 1000 Genomes Project, order delays directly related to stimulus funding under the Recovery Act and the impact of reduced foundation funding at a few key customers.

Total cost of revenue, which excludes the impairment of manufacturing equipment and the amortization of intangible assets, remained flat despite higher sales, primarily due to a decrease in manufacturing costs and improved efficiencies.
Cost of product revenue as a percentage of related revenue was 30% for the year ended January 3, 2010, compared to 36% for the year ended December 28, 2008. The decrease was primarily due to lower costs for our sequencing consumables and instrumentation. The cost of sequencing consumables decreased as a percentage of related revenue due to improved overhead absorption from increased volumes and2011. In addition, we had the benefit of decreased costsa $2.3 million legal settlement gain recorded in selling, general and administrative expenses in 2011.

In Q3 2012, we completed the relocation of our headquarters that started in 2011. During 2012, we incurred $26.3 million in additional headquarter relocation expense, primarily consisting of cease-use loss associated with vacating our prior headquarters, double rent expense during the reformulationtransition to our new facility, and accretion of interest expense on the lease exit liability. Headquarter relocation expense recorded in 2011 consisted of accelerated depreciation and rent expense on the new facility during the transition period of occupying both the current and new facility.

During Q1 2012, CKH Acquisition Corporation and Roche Holding Ltd. (together, “Roche”) made an unsolicited tender offer to purchase all outstanding shares of our sequencing kits launched at the endcommon stock for up to $51.00 per share. During 2012, we recorded $23.1 million of expenses incurred in relation to Roche’s unsolicited tender offer, consisting primarily of legal, advisory, and other professional fees.

In late 2011, we announced restructuring plans to reduce our global workforce and to consolidate certain facilities. As a result of the third quarterrestructuring effort, we recorded additional restructuring charges of 2008.

Duringduring the year ended December 28, 2008, we recorded acquired IPR&D charges of $24.7period. The remaining increase was primarily driven by a $4.0 million increase in bad debt expenses as a result of customer bankruptcies, and a $3.7 million increase in supplies, repairs, and maintenance expenses. These increases were partially offset by a legal settlement gain of $2.3 million, representing the Avantome, Inc. acquisitionpayment we received to settle an outstanding commercial dispute.

In 2011, we relocated our headquarters to another facility in August 2008.

In Q4 2011, we announced a restructuring plan to reduce our global workforce by approximately 200 employees, or approximately 8%, and to consolidate certain facilities. As a result of the restructuring effort, we recorded additional IPR&D chargesa restructuring charge of $11.3$8.1 million during Q4 2011, comprised primarily of severance pay and other employee separation costs.

2012 Compared to 2011

During the fourth quarter of 2012, we recognized a gain of $48.6 million on the sale of our minority ownership interest in deCODE Genetics, a cost-method investment. We also recorded an impairment loss of $2.7 million on another cost-method investment that was determined to be other-than-temporarily impaired.

Interest income decreased despiteincreased in 2012 primarily due to a $6.0 million recovery of a previously impaired note receivable and an increase in realized gains from our average cashinvestment portfolio. Interest expenses in both 2012 and investment balance due to an overall decline in interest rates during 2009. Interest expense increased due to the amortization2011 are primarily comprised of accretion of the discount on our convertible senior notes.

Other (expense) income, net decreased, in 2012 primarily consisted of foreign exchange losses. Other (expense) income, net, in 2011 primarily consisted of a $37.6 million loss on the extinguishment of debt recorded on conversions of our 0.625% convertible senior notes due 2014.


34


2011 Compared to 2010

The decrease in interest income in 2011 compared to 2010 was primarily driven by lower interest rates, despite the increase in our cash, cash equivalents and short-term investment balance during the period. Interest expense increased during the period primarily due to athe accretion of discount on our $920.0 million 0.25% convertible senior notes due 2016 issued in the first half of 2011, partially offset by the decrease in interest expense associated with the repayment of $1.5$349.9 million in gainsprincipal for the 0.625% convertible senior notes due 2014 during 2011.

Other (expense) income, net, in 2011 primarily consisted of a loss of $37.6 million on the extinguishment of debt recorded on conversions of our 0.625% convertible senior notes due 2014 and a $1.1 million foreign exchange loss recorded during the period. The loss on extinguishment of debt was calculated as the difference between the carrying amount of the converted notes and their fair value as of the settlement dates. Other (expense) income, net, foreign currency transactions, which wasin 2010 primarily consisted of a $13.2 million impairment charge related to a cost-method investment and a related note receivable, partially offset by a $2.9 million gain of $0.8 million on acquisition recorded for the conversiondifference between the carrying value of a portioncost method investment prior to the acquisition and the fair value of our debt duringthat investment at the first quartertime of 2009.acquisition, and foreign exchange gains.

Our effective tax rate decreasedwas 32.1% for 2012. The variance from 45.8% in 2008 to 36.7% in 2009 predominately because the amount of nondeductible acquired IPR&D recognized for financial reporting purposes was lower by $13.3 million. Additionally, the percentage of consolidated income before income taxes earned in foreign jurisdictions, which primarily have lower statutory tax rates than the U.S. statutory tax rate increased from 36% in 2008 to 43% in 2009.

Total revenue $573,225  $366,799  $206,426   56%
                 
Product revenue consists primarily of revenue from the sale of consumables and instruments.
Revenue from the sale of consumables increased $140.2 million, or 72%, to $333.7 million for the year ended December 28, 2008 compared to $193.5 million for the year ended December 30, 2007. Growth in consumable revenue was primarily attributable to strong demand for our Infinium and sequencing products, which led to increased sales of $104.8 million and $35.4 million, respectively. The increase in revenue associated with our Infinium products was attributable to the strong demand for our Infinium High-Density BeadChips, particularly the Human610-Quad, which we began shipping during the first quarter of 2008. Of the overall increase in Infinium BeadChip sales, approximately 79% was due to new product introductions with higher average selling prices, while the remaining 21% can be attributed to increased volume. The increase in sequencing consumables35% was primarily attributable to the growthchange in the mix of our installed base of instruments and the progression of customer labs ramping to production scale.
Revenueearnings in tax jurisdictions with different statutory rates. Our future effective tax rate may vary from the sale of instruments increased $64.8 million, or 54%, to $185.7 million for the year ended December 28, 2008 compared to $120.9 million for the year ended December 30, 2007. The increase was primarily attributable to a $63.0 million increase in sales of our Genome Analyzer driven by both an increase in sales volume and average selling prices. Additionally, during the second quarter of 2008, we launched the iScan System, our next-generation BeadChip scanner to replace the BeadArray Reader. Any increase in revenue resulting from shipments of this new system was offset by a reduction in sales of our BeadArray Reader as we stopped manufacturing this product upon the launch of our iScan System.

Total cost of revenue, which excludes the impairment of manufacturing equipment and the amortization of intangible assets, increased primarily due to higher instrument and consumable sales.
Cost of product revenue as a percentage of related revenue was 36% for the year ended December 28, 2008 compared to 37% for the year ended December 30, 2007. The decrease was primarily due to favorable product mix driven by increased sales of our new High-Density Infinium Beadchips, with higher average selling prices as compared to the Infinium Beadchips sold in the prior year. This was partially offset by increased provisions for inventory obsolescence of $7.2 million for the year ended December 28, 2008 compared to $1.9 million for the year ended December 30, 2007. The increase in the inventory reserve was primarily associated with product transitions. During the year, we recorded reserves for product obsolescence associated with the launch of our new Infinium Beadchips and the launch of a new sequencing kit. Instrument cost of sales as a percentage of related revenue increased slightly over the prior year due to lower average selling prices mainly associated with promotional campaigns as we launched our next generation Beadarray Reader, the iScan in the first half of 2008.

The main driversfactors described in the change in net operating assets included increases in accounts receivable, inventory, accounts payable and accrued liabilities. These increases were primarily related to the growth of our business.
Investing Activities
Cash used in investing activities totaled $255.7 million for the year ended January 3, 2010. We purchased and soldavailable-for-sale securities totaling $694.5 million and $515.2 million, respectively. We incurred $51.8 million in capital expenditures primarily associated with the expansion of our facilities and infrastructure at our San Diego, Hayward and UK locations. Additionally, in January 2009, we executed a strategic alliance with Oxford Nanopore Technologies, which consisted of a commercialization agreement and an $18.0 million equity investment. We also agreed to make an additional equity investment upon the achievement of a specific technical milestone.
In August 2008, we completed our acquisition of Avantome, Inc. As consideration for the acquisition, we paid $25.8 million in cash, including transaction costs, at the closing of the acquisition, and have subsequently paid $15.0 million as of February 1, 2010 based on the achievement of, or amendments relating to, certain milestones. We may pay up to an additional $20.0 million in contingent cash consideration to Avantome’s former shareholders based on the achievement of certain remaining milestones.
In January 2008, as part of our Affymetrix settlement, we recorded a $36.0 million intangible asset for licensed technology obtained in the settlement. See Note 4 of Notes to Consolidated Financial Statements for further information regarding intangible assets.
In January of 2007, we completed our acquisition of Solexa, Inc. in astock-for-stock merger transaction. The Company issued approximately 26.2 million shares of its common stock as consideration for this merger. The acquisition resulted in net cash acquired of $72.1 million.
Financing Activities
Cash used in financing activities totaled $98.9 million for the year ended January 3, 2010. During the year we repurchased approximately 6.1 million shares of our common stock for $175.1 million, which was partially offset by $39.4 million in proceeds received from the exercise of stock options and the sale of shares under our Employee Stock Purchase Plan and $39.3 million of incremental tax benefits related to stock options exercised.

In August 2008, we issued a total of 8.1 million shares at a public offering price of $43.75 per share, raising net proceeds to the Company of $342.7 million, after deducting underwriting discounts and commissions and offering expenses. During the year ended December 28, 2008, we also repurchased approximately 3.1 million shares of our common stock for $70.8 million.
In February 2007, we issued $400.0 million principal amount of 0.625% convertible senior notes due 2014. The net proceeds from the offering, after deducting the initial purchasers’ discount and offering expenses, were approximately $390.3 million. We used $201.6 million of the net proceeds to purchase approximately 11.6 million shares of our common stock in privately negotiated transactions concurrently with the offering. We used $46.6 million of the net proceeds of this offering to pay the net cost of convertible note hedge and warrant transactions, which are designed to reduce the potential dilution upon conversion of the notes. See Note 7 of Notes to Consolidated Financial Statements for further information regarding our convertible senior notes.
Liquidity
We manage our business to maximize operating cash flows as the“Cash Flow Summary” below. Our primary source of our liquidity.liquidity has been cash flows from operations. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing, and financing needs. Cash and cash equivalents held by our foreign subsidiaries at December 30, 2012 were approximately $265.5 million. It is our intention to indefinitely reinvest all current and future foreign earnings in foreign subsidiaries.

Historically, we have liquidated our short-term investments and/or issued debt and equity securities to finance our requirementsbusiness needs as a supplement to the extent that cash provided by operating activities was not sufficient to fund our needs. We may require additional fundingactivities. At December 30, 2012, we have $916.2 million in the future and our failure to raise capital on acceptable terms, when needed, could have a material adverse effect on our business.

At January 3, 2010, we had approximately $693.5 million in cash and short-term investments. Short-termOur short-term investments include marketable securities and auction rate securities totaling $494.0 million and $54.9 million, respectively. Our marketable securities consistconsisting of debt securities in government sponsoredgovernment-sponsored entities, corporate debt securities, and U.S treasuryU.S. Treasury notes. We do not hold securities backed by mortgages. Our auction rate securities were

In 2011, we issued primarily by municipalities and universities. The markets for auction rate securities effectively ceased when the vast majority$920.0 million in principal amount of auctions failed in February 2008, preventing investors from selling their auction rate securities. As of January 3, 2010, the securities continued to fail auction and remained illiquid. In November 2008, we signed a settlement agreement allowing us to sell our auction rate securities at par value to UBS AG (UBS) at our discretion during the period of June 30, 2010 through July 2, 2012. Because we intend to exercise this right when it becomes available, we have classified our auction rate securities as short-term on the balance sheet. See Note 3 of Notes to Consolidated Financial Statements for further information regarding our auction rate securities.
Our outstanding convertible senior notes were convertible into cash and, if applicable, shares of our common stock for the period from April 1, 2008 through December 31, 2008 and became convertible again beginning April 1, 2009 through December 31, 2009. On December 29, 2008, a noteholder converted notes in an aggregate principal amount of $10.0 million. On February 4, 2009, the settlement date, we paid the noteholder the conversion value of the notes in cash, up tothat mature on March 15, 2016 (2016 notes). We pay 0.25% interest per annum on the principal amount of the notes. The excess2016 notes semi-annually in arrears in cash on March 15 and September 15 of the conversion value overeach year. In 2007, we issued $400.0 million in principal of convertible senior notes that mature on February 15, 2014 (2014 notes). We pay 0.625% interest per annum on the principal amount totaling $2.9 million, was paid in shares of common stock. This equity dilution upon conversion of the 2014 notes was offset by the reacquisitionsemi-annually in arrears in cash on February 15 and August 15 of the shares undereach year. Additional information about the convertible notes, including their conversion features, is described in note hedge transactions entered into“7. Convertible Senior Notes” in connection withPart II, Item 8, of this Form 10-K. As of December 30, 2012, the offeringprincipal amounts of the notes. See Note 7our 2016 notes and 2014 notes were $920.0 million and $40.1 million, respectively. Our commitment of Notes to Consolidated Financial Statements for further discussion of the terms of the convertible senior notes.interest payment on these outstanding notes is $8.4 million on an annual basis.

Our primary short-term needs for capital, which are subject to change, include expenditures related to:
support of commercialization efforts related to our current and future products, including expansion of our direct sales force and field support resources both in the United States and abroad;
• potential strategic acquisitions and investments;
• support of our commercialization efforts related to our current and future products, including expansion of our direct sales force and field support resources both in the United States and abroad;

In 2012, we acquired BlueGnome for total cash and other consideration of $95.5 million, which included $7.5 million in fair value of contingent cash consideration. In 2011, we acquired Epicentre for total cash and other consideration of $71.4 million, which included $4.6 million in the fair value of contingent consideration settled in stock and $7.4 million in the fair value of contingent cash consideration.

• improvements in our manufacturing capacity and efficiency; and
• the expansion needs of our facilities, including costs of leasing additional facilities.
Our Board of Directors has authorized several common stock repurchase programs. In 2012, we used $82.5 million to repurchase our outstanding shares under these programs. As of December 30, 2012, we had authorization from our Board of Directors to repurchase to an additional $167.5 million of our common stock.

During 2011, we used $314.3 million of the net proceeds from the issuance of our 2016 notes to purchase 4.9 million shares of our common stock in privately negotiated transactions concurrently with the issuance. We also used part of the net proceeds for the extinguishment of $349.9 million principal amount of our 2014 notes upon conversion. We used the remaining net proceeds for other general corporate purposes, which included acquisitions and purchases of our common stock.

We expect that our product revenue and the resulting operating income, as well as the status of each of our new product development programs, will significantly impact our cash management decisions.

We anticipate that our current cash, and cash equivalents and income from operationsshort-term investments, together with cash provided by operating activities will be sufficient to fund our near term capital and operating needs in 2010, barring unforeseen circumstances.for at least the next 12 months, including the pending acquisition of Verinata. Operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. At the present time, we have no material commitments for capital expenditures. Our future capital requirements and the adequacy of our available funds will depend on many factors, including:
• our ability to successfully commercialize and further develop our technologies and create innovative products in our markets;
• scientific progress in our research and development programs and the magnitude of those programs;
• competing technological and market developments; and
• the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings.

The table excludes $37.6 million of uncertain tax benefits. We have not included this amount in the table because we cannot make a reasonably reliable estimate regarding the timing of settlements with taxing authorities, if any. See Note 11note “13. Income Taxes” in Part II, Item 8 of Notes to the Consolidated Financial Statementsthis Form 10-K for further discussion of our uncertain tax positions. The table also excludes $35.0 million in potential contingent consideration payments related to acquisitions. We have not included this amount in the table because we cannot make a reasonably reliable estimate regarding whether the milestones required for these payments will be achieved. See note “4. Acquisitions” in Part II, Item 8 of this Form 10-K for further discussion of our contingent consideration.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Management bases its estimates on historical experience, market and other conditions, and various other assumptions it believes to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact us in the future, the estimation process is, by its nature, uncertain given that estimates depend on events over which we may not have control. If market and other conditions change from those that we anticipate, our consolidated financial statements may be materially affected. In addition, if our assumptions change, we may need to revise our estimates, or take other corrective actions, either of which may also have a material effect on our consolidated financial statements.

We believe that the following critical accounting policies and estimates have a higher degree of inherent uncertainty and require our most significant judgments. In addition, had we used estimates different from any of these, our consolidated financial statements could have been materially different from those presented. Members of our senior management have discussed the development and selection of our critical accounting policies and estimates, and our disclosure regarding them, with the audit committee of our board of directors. Our accounting policies are more fully described in Note 1note “1. Organization and Significant Accounting Policies” in Part II, Item 8 of the Consolidated Financial Statements.this Form 10-K.

Revenue Recognition

Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of arrays, reagents, flow cellsinstruments and instrumentation.consumables used in genetic analysis. Service and other revenue primarily consists of revenue received for performingfrom instrument service contract sales, genotyping and sequencing services, extended warranty sales and amounts earned under research agreements with government grants, which are recognized in the period during which the related costs are incurred. The timing of revenue recognition and the amount of revenue actually recognized in each case depends upon a variety of factors, including the specific terms of each arrangement and the nature of our deliverables and obligations. Determination of the appropriate amount of revenue recognized involves significant judgments and estimates and actual results may differ from our estimates.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price to the buyer is fixed or determinable, and collectibility is reasonably assured. In instances where final acceptance of the product or system is required, revenue is deferred until all the acceptance criteria have been met. All revenue is recorded net of any discounts.

Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided that no significant obligations remain and collection of the receivable is reasonably assured. Revenue forfrom instrument service contracts is recognized as the services are rendered, typically evenly over the contract term. Revenue from genotyping and sequencing services is recognized when earned, which is generally at the time the genotyping or sequencing analysis data is deliveredmade available to the customer or agreed-toagreed upon milestones are reached.

In order to assess whether the price is fixed or determinable, we ensureevaluate whether refund rights exist. If there are no refund rights. Ifrights or payment terms are based on future performance, we defer revenue recognition until the price becomes fixed or determinable. We assess collectibility based on a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection of a payment is not reasonably assured, revenue recognition is deferred until the time collection becomes reasonably assured, which is generally upon receipt of payment.


41


Sales of instrumentation generally include a standard one-year warranty. We also sell separately priced maintenance (extended warranty) contracts, which are generally for one year, starting upon the expiration of the initial warranty. Revenue for extended warranty sales is recognized ratably over the term of the extended warranty period. Reserves are provided for estimated product warranty expenses at the time the associated revenue is recognized. If we were to experience an increase in warranty claims or if costs of servicing its products under warranty were greater than its estimates, gross margins could be adversely affected.
We regularly enter into contracts where revenue is derived from multiple deliverables including any mix of productsand/or services. These productsand/or services are generally delivered within a short time frame, approximately three to six months, of the contract execution date. Revenue recognition for contracts with multiple deliverables is based on the individual units of accounting determined to exist in the contract. A delivered item is considered a separate unit of accounting when the delivered item has value to the customer 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.

For transactions entered into in 2009,with multiple deliverables, consideration is allocated at the inception of the contract to all deliverables based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective

39


evidence (VSOE) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence exists, we use best estimate of the selling price for the deliverable. SeeRecent Accounting Pronouncementsin Note 1 of Notes to Consolidated Financial Statements for further information related to our change in authoritative accounting guidance for revenue recognition.
For transactions entered into prior to 2009, consideration was generally allocated to each unit of accounting based upon its relative fair value when objective and reliable evidence of fair value existed for all units of accounting in an arrangement. The fair value of an item was generally the price charged for the product, if the item was regularly sold on a stand-alone basis. In those instances when objective and reliable evidence of fair value existed for the undelivered items but not for the delivered items, the residual method was used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equaled the total arrangement consideration less the aggregate fair value of the undelivered items. When we were unable to establish stand-alone value for delivered items or when fair value of undelivered items had not been established, revenue was deferred until all elements were delivered and services had been performed, or until fair value could objectively be determined for any remaining undelivered elements.

In order to establish VSOE of selling price, we must regularly sell the productand/or service on a standalone basis with a substantial majority priced within a relatively narrow range. VSOE of selling price is usually the midpoint of that range. If there isare not a sufficient number of standalone sales and VSOE of selling price cannot be determined, then we consider whether third party evidence can be used to establish selling price. Due to the lack of similar products and services sold by other companies within the industry, we have rarely established selling price using third-party evidence. If neither VSOE nor third party evidence of selling price exists, we determine itsour best estimate of selling price using average selling prices over a rolling 12 month12-month period as well ascoupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by our pricing committee adjusted for applicable discounts.
We recognize revenue for delivered elements only when we determine there are no uncertainties regarding customer acceptance.

InvestmentsIn 2010, we offered an incentive with the launch of the HiSeq 2000 that enabled existing Genome Analyzer customers to trade in their Genome Analyzer and receive a discount on the purchase of a HiSeq 2000. The incentive was limited to customers who had purchased a Genome Analyzer as of the date of the announcement and was the first significant trade-in program we have offered. The Genome Analyzer trade-in program was completed in 2011. We accounted for HiSeq 2000 discounts related to the trade-in program as reductions to revenue upon recognition of the HiSeq 2000 sales revenue, which is later than the date the trade-in program was launched.

In certain markets, the Company sells products and provides services to customers through distributors that specialize in life science products. In most sales through distributors, the product is delivered directly to customers. In cases where the product is delivered to a distributor, revenue recognition is deferred until acceptance is received from the distributor, and/or the end-user, if required by the applicable sales contract. The terms of sales transactions through distributors are consistent with the terms of direct sales to customers. These transactions are accounted for in accordance with the Company’s revenue recognition policy described herein.

Investments

We determineinvest in various types of securities, including debt securities in government-sponsored entities, corporate debt securities, and U.S. treasury securities. As of December 30, 2012, we have $916.2 million in short-term investments. In accordance with the accounting standard for fair value measurements, we classify our investments as Level 1, 2, or 3 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets that we have the ability to access. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset.
As discussed in note “6. Fair Value Measurements” in Part II, Item 8 of this Form 10-K, a majority of our security holdings have been classified as Level 2. These securities have been initially valued at the transaction price and subsequently valued utilizing a third party service provider who assesses the fair value using inputs other than quoted prices that are observable either directly or indirectly, such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. We perform certain procedures to corroborate the fair value of our assetsthese holdings, and liabilities based on 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 maximize the use of observable inputsprocess, we apply judgments and minimize the use


42


of unobservable inputs. We use a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value:
• 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.
In using this fair value hierarchy, management may be required to make assumptions of pricing by market participants and assumptions about risk, specifically when using unobservable inputs to determine fair value. These assumptions are judgmental in nature and mayestimates that if changed, could significantly affect our results of operations.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We evaluate the collectibility of our accounts receivable based on a combination of factors. We regularly analyze customer accounts, review the length of time receivables are outstanding, review historical loss rates and assess current economic trends that may impact the level of credit losses in the future. Our gross trade accounts receivables totaled $219.3 million and the allowance for doubtful accounts was $4.3 million at December 30, 2012. Our allowance for doubtful accounts has generally been adequate to cover our actual credit losses. However, since we cannot reliably predict future changes in the financial stability of our customers, we cannot guarantee thatmay need to increase our reserves will continue to be adequate.if the financial conditions of our customers deteriorate.


40


Inventory Valuation

Inventories are stated at lower of cost or market. We record adjustments to inventory for potentially excess, obsolete, or impaired goods in order to state inventory at net realizable value. We must make assumptions about future demand, market conditions, and the release of new products that will supersede old ones. We regularly review inventory for excess and obsolete products and components, taking into account product life cycle and development plans, product expiration andcycles, quality issues, historical experience, and usage forecasts. Our gross inventory totaled $178.6 million and the cumulative adjustment for potentially excess and obsolete inventory was $19.9 million at December 30, 2012. Historically, our current inventory levels. Ifadjustment has been adequate to cover our losses. However, if actual market conditions are less favorable than anticipated, additional inventory adjustments could be required.

Contingencies

We are subject to legal proceedings primarily relatedinvolved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. We routinely assess the likelihood of adverse judgments or outcomes toIn connection with these matters, as well as rangeswe assess, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the financial statements if it is believed to be probable losses, tothat a loss has been incurred and the extent losses areamount of the loss can be reasonably estimable. If losses are probableestimated. Because litigation is inherently unpredictable and reasonably estimable, we will record a liability and an expense for the estimated loss. Disclosure for specific legalunfavorable resolutions could occur, assessing contingencies is provided ifhighly subjective and requires judgments about future events. We regularly review outstanding legal matters to determine the likelihoodadequacy of occurrence is probablethe liabilities accrued and the exposure is considered material to the consolidated financial statements. In making determinationsrelated disclosures in consideration of likely outcomes of litigation matters, management considers many factors. These factors, which include, but are not limited to, past history, scientific and other evidence, and the specifics and status of each matter. We may change our estimates if our assessment of the various factors changes whichand the amount of ultimate loss may result in the recording of an accrual or a changediffer from our estimates, resulting in a previously recorded accrual. Predicting the outcomematerial effect on our business, financial condition, results of claims and litigation, and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates and accruals.operations, and/or cash flows.

Business Combinations and Intangible Asset Valuation

Under the purchaseacquisition method of accounting, we allocate the purchase pricefair value of acquired companiesthe total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values.values on the date of acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. We record the excess of purchase priceconsideration over the aggregate fair valuesvalue of tangible and intangible assets, net of liabilities assumed, as goodwill. We engage third-party appraisal firms to assist us in determining the fair values of assets acquired and liabilities assumed. These


43


valuations require us to make significant estimates and assumptions, especially with respect to intangible assets.

The Company’s intangible assets are comprised primarilyIn connection with certain of licensed technology fromour acquisitions, additional contingent consideration is earned by the Affymetrix settlement entered intosellers upon completion of certain future performance milestones. In these cases, a liability is recorded on January 9, 2008the acquisition date for an estimate of the acquisition date fair value of the contingent consideration by applying the income approach utilizing variable inputs such as anticipated future cash flows, risk-free adjusted discount rates, and acquired core technologynonperformance risk. Any change in the fair value of the contingent consideration subsequent to the acquisition date is recognized in acquisition related expense (gain), net, a component of operating expenses, in our consolidated statements of income. This method requires significant management judgment, including the probability of achieving certain future milestones and customer relationships fromdiscount rates. Future changes in our estimates could result in expenses or gains.

Management typically uses the Solexa acquisition. Management uses a discounted cash flow method to value our acquired intangible assets. This method requires significant management judgment to forecast future operating results and establish residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed.

Goodwill, Intangible Assets and Other Long-Lived Assets — Impairment Assessments

We estimateregularly perform reviews to determine if the fair valuecarrying values of our long-lived assets are impaired. A review of identifiable intangible assets and other long-lived assets that have finite useful lives wheneveris performed when an event or change in circumstances indicates thatoccurs indicating the carrying value of the asset may not be recovered through undiscounted future operating cash flows. We testpotential for potential impairment of goodwill annually in our second fiscal quarter or wheneverimpairment. If indicators of impairment arise.exist, we assess the recoverability of the affected long-lived assets and compare their fair values to the respective carrying amounts.


41


In order to estimate the fair value of purchasedidentifiable intangible assets and other long-lived assets, that have finite useful lives, we estimate the present value of future cash flows from those assets. The key assumptions that we use in our discounted cash flow model are the amount and timing of estimated future cash flows to be generated by the asset over an extended period of time and a rate of return that considers the relative risk of achieving the cash flows, and the time value of money.money, and other factors that a willing market participant would consider. Significant judgment is required to estimate the amount and timing of future cash flows and the relative risk of achieving those cash flows. We had a total of $213.4 million in goodwill, $117.2 million in net property and equipment and $43.8 million in net intangible assets on our balance sheet at January 3, 2010.
In order to estimate the fair value of goodwill, we use a weighted combination of a discounted cash flow model (known as the income approach) and comparisons to publicly traded companies engaged in similar businesses (known as the market approach). The income approach requires us to use a number of assumptions, including market factors specific to the business, the amount and timing of estimated future cash flows to be generated by the business over an extended period of time, long-term growth rates for the business, and a rate of return that considers the relative risk of achieving the cash flows and the time value of money. Although the assumptions we use in our discounted cash flow model are consistent with the assumptions we use to generate our internal strategic plans and forecasts, significant judgment is required to estimate the amount and timing of future cash flows and the relative risk of achieving those cash flows. When using the market approach, we make judgments about the comparability of publicly traded companies engaged in similar businesses. We base our judgments on factors such as size, growth rates, profitability, risk, and return on investment. We also make judgments when adjusting market multiples of revenue, operating income, and earnings for these companies to reflect their relative similarity to our own businesses.

Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of one or more of our reporting units, we may be required to record future impairment charges for purchased intangible assets and goodwill.assets. Impairment charges could materially decrease our future net income and result in lower asset values on our balance sheet.

Convertible Senior Notes
Share-Based Compensation
During the first quarter of 2009, we adopted new authoritative guidance that significantly impacts the accounting for our convertible senior notes by requiring us to account separately for the liability and equity components of the notes. The liability component is measured so the effective interest expense associated with the notes reflects the issuer’s borrowing rate at the date of issuance for similar debt instruments without the conversion feature. The difference between the cash proceeds associated with the notes and this estimated fair value is recorded as a debt discount and amortized to interest expense over the life of the notes.
Determining the fair value of the liability component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the liability component and, in effect, the associated interest expense. According to the guidance, the carrying amount of the liability component is determined by measuring the fair value of a similar liability that does not have an associated equity component. If no similar liabilities exist, estimates of fair value are primarily determined using assumptions that market participants would use in pricing the liability component, including market interest rates, credit standing, yield curves and volatilities.
Stock-Based Compensation

We are required to measure and recognize compensation expense for all stock-based payment awards made to employees and directorsshare-based payments based on estimated fair value. We estimate the fair value of stock options granted and stock purchases under our employee stock purchase plan using the Black-Scholes-Merton (BSM) option-pricing model. The fair value of our restricted stock units is based on the market price of our common stock on the date of grant.

The determination of fair value of stock-basedshare-based awards using the BSM model requires the use of certain estimates and highly judgmental assumptions that affect the amount of stock-basedshare-based compensation expense recognized in our Consolidated Statementsconsolidated statements of Operations.income. These include estimates of the expected volatility of our stock price, expected option life of an award, expected dividends, and the risk-free interest rate. We determine the volatility of our stock price by equally weighing the historical and implied volatility of our common stock. The historical volatility of our common stock over the most recent period is generally commensurate with the estimated expected life of our stock options,awards, adjusted for the impact of unusual fluctuations not reasonably expected to recur, and other relevant factors. Implied volatility is calculated from the implied market volatility of exchange-traded call options on our common stock. The expected option life of an award is based on historical forfeiture experience, exercise activity, and on the terms and conditions of the stock awards granted to employees.awards. We determined expected dividend yield to be 0% given we have never declared or paid any cash dividends on our common stock and we currently do not anticipate paying such cash dividends. The risk-free interest rate is based upon U.S. Treasury securities with remaining terms similar to the expected term of the share-based awards. We amortize the fair value of share-based compensation on a straight-line basis over the requisite service periods of the awards. If any of the assumptions used in the BSM model change significantly, stock-basedshare-based compensation expense may differ materially from what we have recorded in the current period.

Warranties

We generally provide a one-year warranty on instruments. Additionally, we provide a warranty on consumables through the expiration date, which generally ranges from six to twelve months after the manufacture date. We establish an accrual for estimated warranty expenses based on historical experience as well as anticipated product performance. We periodically review the adequacy of our warranty reserve, and adjust, if necessary, the warranty percentage and accrual based on actual experience and estimated costs to be incurred. If our estimates of warranty obligation change or if actual product performance is below our expectations we may incur additional warranty expense.

Cease-Use Loss upon Exit of Facility

In 2012, we completed the relocation of our headquarters to a new facility in San Diego, California, and recorded headquarter relocation expense of $26.3 million, the majority of which was attributable to a cease-use loss recorded upon vacating our prior headquarter facility. The lease on our prior headquarter facility expires in 2023. The cease-use loss is calculated as the present value of the remaining lease obligation offset by estimated sublease rental receipts during the remaining lease period, adjusted for deferred items and leasehold improvements. In calculating the cease-use loss, management is required to make significant judgments to estimate the present value of future cash flows from the assumed sublease. The key assumptions that we use in our discounted cash flow model include the amount and timing of estimated sublease rental receipts, and the risk-adjusted discount rate. These assumptions are subjective in nature and the actual future cash flows could differ from our estimates, resulting in significant adjustments to the cease-use loss recorded.


42


Income Taxes

Our provision for income taxes, deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect our best assessment of estimated future taxes to be paid. Significant judgments and estimates based on interpretations of existing tax laws or regulations in the U.S.United States and the numerous foreign jurisdictions where we are subject to income tax are required in determining our provision for income taxes. Changes in tax laws, statutory tax rates, and estimates of the company’s future taxable income could impact the deferred tax assets and liabilities provided for in the consolidated financial statements and would require an adjustment to the provision for income taxes.

Deferred tax assets are regularly assessed to determine the likelihood they will be recovered from future taxable income. A valuation allowance is established when we believe it is more likely than not the future realization of all or some of a deferred tax asset will not be achieved. In evaluating our ability to recover deferred tax assets within the jurisdiction which they arise, we consider all available positive and negative evidence. Factors reviewed include the cumulative pre-tax book income for the past three years, scheduled


45


reversals of deferred tax liabilities, our history of earnings and reliable forecasting,reliability of our forecasts, projections of pre-tax book income over the foreseeable future, and the impact of any feasible and prudent tax planning strategies. Based on the available evidence as of January 3, 2010,December 30, 2012, we were not able to conclude it is more likely than not certain U.S. and foreign deferred tax assets will be realized. Therefore, we recorded a valuation allowance of $2.8$1.8 million and $12.1 million against certain U.S. and foreign deferred tax assets, respectively.assets.

We recognize the impact of a tax position in our 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. Tax authorities regularly examine our returns in the jurisdictions in which we do business and we regularly assess the tax risk of the company’s return filing positions. Due to the complexity of some of the uncertainties, the ultimate resolution may result in payments that are materially different from our current estimate of the tax liability. These differences, as well as any interest and penalties, will be reflected in the provision for income taxes in the period in which they are determined.

Interest Rate Sensitivity

Our exposureinvestment portfolio is exposed to market risk forfrom changes in interest rates relates primarily to our investment portfolio.rates. The fair market value of fixed rate securities may be adversely impacted by fluctuations in interest rates while income earned on floating rate securities may decline as a result of decreases in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We attempt to ensure the safety and preservation of our invested principal funds by limiting default risk, market risk, and reinvestment risk. We mitigate default risk by investing in investment grade securities. We have historically maintained a relatively short average maturity for our investment portfolio, and we believe a hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of our interest sensitive financial instruments. For example,In addition, if a 100 basis point change in overall interest rates were to occur in 2010,2013, our interest income would change by approximately $6.9$13.5 million in relation to amounts we would expect to earn, based on our cash, cash equivalents, and short-term investments as of January 3, 2010.December 30, 2012.

Changes in interest rates may also impact gains or losses from the conversion of our outstanding convertible senior notes.During 2011, we issued $920 million in aggregate principal amount of our 0.25% convertible senior notes due 2016. At our election, the notes are convertible into cash, shares of our common stock, or a combination of cash and shares of our common stock in each case under certain circumstances, including trading price conditions related to our common stock. If the trading price of our common stock reaches a price for a sustained period at 130% above the conversion price of $83.55, the notes will become convertible. Upon conversion, we are required to record a gain or loss for the difference between the fair value of the debt to be extinguished and its corresponding net carrying value. The fair value of the debt to be extinguished depends on our then-current incremental borrowing rate. If our incremental borrowing rate at the time of conversion is higher or lower than the implied interest rate of the notes, we will record a gain or loss in our consolidated statement of income during the period in which the notes are converted. The implicit interest rate for the notes is 4.5%. An incremental borrowing rate that is a hypothetical 100 basis points lower than the implicit interest rate upon conversion of $100 million aggregate principal amount of the notes would result in a loss of approximately $3.0 million.


43


Market Price Sensitive Instruments

In order to reduce potential equity dilution, in connection with the issuance (and potential conversion) of our 0.625% convertible senior notes due 2014, we entered into convertible note hedge transactions, entitling us to purchase up to 18,322,32018,322,000 shares of our common stock at a strike price of $21.83 per share, subject to adjustment. In addition, we sold to the hedge transaction counterparties warrants exercisable on a net-share basis, for up to 18,322,32018,322,000 shares of our common stock at a strike price of $31.435 per share, subject to adjustment. The anti-dilutive effect of the note hedge transactions, if any, could be partially or fully offset to the extent the trading price of our common stock exceeds the strike price of the warrants on the exercise dates of the warrants, which occur during 2014, assuming the warrants are exercised.

The value of these monetary assets and liabilities are subject to changes in currency exchange rates from the time the transactions are originated until settlement in cash. Our foreign currency exposures are primarily concentrated in the Euro, Yen, British pound sterling, Australian dollar, and Singapore dollar.

We only use derivative financial instruments to reduce foreign currency exchange rate risks; we do not hold any derivative financial instruments for trading or speculative purposes. We primarily use forward exchange contracts to hedge foreign currency exposures, and they generally have terms of one month or less. Realized and unrealized gains or losses on the value of financial contracts entered into to hedge the exchange rate exposure of these monetary assets and liabilities are also included in the determination of net income, (loss), as they have not been designated for hedge accounting. These contracts, which settle monthly, effectively fix the exchange rate at which these specific monetary assets and liabilities will be settled, so that gains or losses on the forward contracts offset the losses or gains from changes in the value of the underlying monetary assets and liabilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Unless the context requires otherwise, references in this report to “Illumina,” “we,” “us,” the “Company,” and “our” refer to Illumina, Inc. and its consolidated subsidiaries.

Item 9.1.Changes InOrganization and Disagreements with Accountants onSummary of Significant Accounting and Financial Disclosure.Policies

None.Organization and Business

Illumina, Inc. is a leading developer, manufacturer, and marketer of life science tools and integrated systems for the analysis of genetic variation and function. Using its proprietary technologies, Illumina provides a comprehensive line of genetic analysis solutions, with products and services that address a broad range of highly interconnected markets, including sequencing, genotyping, gene expression, and genomic-based diagnostics. The Company’s customers include leading genomic research centers, academic institutions, government laboratories, and clinical research organizations, as well as pharmaceutical, biotechnology, agrigenomics, consumer genomics companies, and in vitro fertilization clinics.

Basis of Presentation

The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Fiscal Year

The Company’s fiscal year is 52 or 53 weeks ending the Sunday closest to December 31, with quarters of 13 or 14 weeks ending the Sunday closest to March 31, June 30, September 30, and December 31. The years ended December 30, 2012, January 1, 2012, and January 2, 2011 were 52 weeks, respectively.

Use of Estimates

The preparation of financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures of contingent assets and liabilities. Actual results could differ from those estimates.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Segment Information

The Company is organized in two operating segments for purposes of recording and reporting our financial results: Life Sciences and Diagnostics. The Life Sciences operating segment includes all products and services related to the research market, namely the product lines based on the Company’s sequencing, BeadArray, and real-time polymerase chain reaction (PCR) technologies. The Diagnostics operating segment focuses on the clinical and personalized application of our products and services for such uses as diagnosing disease, identifying genetic abnormalities, and identifying effective treatment therapies, with an initial emphasis on reproductive health and cancer. During all periods presented, the Diagnostics operating segment had been immaterial to the financial statements as a whole. Accordingly, the Company’s operating results for both segments are reported on an aggregate basis as one reportable segment. The Company will begin reporting in two reportable segments once revenue, operating profit or loss, or asset of the Diagnostics operating segment exceeds 10% of the consolidated amounts.

Acquisitions

The Company measures all assets acquired and liabilities assumed, including contingent considerations and all contractual contingencies, at fair value as of the acquisition date. Contingent purchase considerations settled in cash are remeasured to estimated fair value at each reporting period with the change in fair value recorded in acquisition related expense (gain), net, a component of operating expenses. In addition, the Company capitalizes in-process research and development (IPR&D) and either amortizes it over the life of the product upon commercialization, or writes it off if the project is abandoned

53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

or impaired. Post-acquisition adjustments related to business combination deferred tax asset valuation allowances and liabilities for uncertain tax positions are recorded in current period income tax expense.

Cash Equivalents and Short-Term Investments

Cash equivalents are comprised of short-term, highly liquid investments with maturities of 90 days or less at the date of purchase.

Short-term investments consist of U.S. treasury securities, debt securities in U.S. government-sponsored entities, and corporate debt securities. Management classifies short-term investments as available-for-sale at the time of purchase and evaluates such classification as of each balance sheet date. All short-term investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income, a component of stockholders’ equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other (expense) income, net in the consolidated statements of income.

Fair Value Measurements

The Company determines the fair value of its assets and liabilities based on 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 maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value:

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 carrying amounts of financial instruments such as cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued liabilities, excluding acquisition related contingent consideration liabilities, approximate the related fair values due to the short-term maturities of these instruments.

Accounts Receivable

Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. The Company reserves specific receivables if collectibility is no longer reasonably assured. The Company also reserves a percentage of its trade receivable balance based on collection history and current economic trends that might impact the level of future credit losses. The Company re-evaluates such reserves on a regular basis and adjusts its reserves as needed.

Concentrations of Risk

The Company operates in markets that are highly competitive and rapidly changing. Significant technological changes, shifting customer needs, the emergence of competitive products or services with new capabilities, and other factors could negatively impact the Company’s operating results. A significant portion of the Company’s customers consist of university and research institutions that management believes are, to some degree, directly or indirectly supported by the United States Government. A significant change in current research funding, particularly with respect to the National Institutes of Health, could have a material adverse impact on the Company’s future revenues and results of operations.

The Company is also subject to risks related to its financial instruments including its cash and cash equivalents, investments, and accounts receivable. Most of the Company’s cash and cash equivalents as of December 30, 2012 were deposited with U.S. financial institutions, either domestically or with their foreign branches. The Company’s investment policy

54

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

restricts the amount of credit exposure to any one issuer to 5% of the portfolio at the time of purchase and to any one industry sector, as defined by Bloomberg classifications, to 25% of the portfolio at the time of purchase. There is no limit to the percentage of the portfolio that may be maintained in U.S. treasury securities, debt securities in U.S. government-sponsored entities, and money market funds.

The Company’s products require customized components that currently are available from a limited number of sources. The Company obtains certain key components included in its products from single vendors.

The Company performs a regular review of customer activity and associated credit risks and does not require collateral or enter into netting arrangements. Shipments to customers outside the United States comprised 51%, 50%, and 45% of the Company’s revenue for the years ended December 30, 2012, January 1, 2012, and January 2, 2011, respectively. Customers outside the United States represented 54% and 52% of the Company’s gross trade accounts receivable balance as of December 30, 2012 and January 1, 2012, respectively.

International sales entail a variety of risks, including currency exchange fluctuations, longer payment cycles, and greater difficulty in accounts receivable collection. The Company is also subject to general geopolitical risks, such as political, social and economic instability, and changes in diplomatic and trade relations. The risks of international sales are mitigated in part by the extent to which sales are geographically distributed. The Company has historically not experienced significant credit losses from investments and accounts receivable. Approximately 18% of the Company’s revenue is derived from European countries other than the United Kingdom. As the credit and economic conditions in certain southern European countries continue to deteriorate, the Company regularly reviews its accounts receivable outstanding in these countries and assesses the allowance for doubtful accounts accordingly. As of December 30, 2012, outstanding accounts receivables beyond standard payment terms from these countries accounted for approximately 5% of the Company’s accounts receivable balance, and the Company has not experienced significant difficulties in collecting the accounts receivable outstanding in these countries.

Inventory

Inventory is stated at the lower of cost (on a first in, first out basis) or market. Inventory includes raw materials and finished goods that may be used in the research and development process and such items are expensed as consumed or expired. Provisions for slow moving, excess, and obsolete inventories are estimated based on product life cycles, quality issues, historical experience, and usage forecasts.

Property and Equipment

Property and equipment are stated at cost, subject to review of impairment, and depreciated over the estimated useful lives of the assets (generally three to seven years) using the straight-line method. Amortization of leasehold improvements is recorded over the shorter of the lease term or the estimated useful life of the related assets. Maintenance and repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in operating expense.

Goodwill, Intangible Assets and Other Long-Lived Assets

Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. The change in the carrying value of goodwill during the year ended December 30, 2012 was due to goodwill recorded in connection with the BlueGnome acquisition. Goodwill is reviewed for impairment at least annually during the second quarter, or more frequently if an event occurs indicating the potential for impairment. During its goodwill impairment review, the Company may assess qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the overall financial performance of the Company. If, after assessing the totality of these qualitative factors, the Company determines that it is not more likely than not that the fair value of its reporting unit is less than its carrying amount, then no more assessment is deemed necessary. Otherwise, the Company proceeds to perform the two-step test for goodwill impairment. The first step involves comparing the estimated fair value of the reporting unit with its carrying value, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment test to determine the amount of loss, which involves comparing the implied fair value of the goodwill to the carrying value of the goodwill. The Company may also elect to bypass the qualitative assessment in a period and elect to proceed to perform the first step of the goodwill impairment test. The Company performed its annual assessment for goodwill impairment in the second quarter of 2012, noting no impairment.

55

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


The Company’s identifiable intangible assets are typically comprised of acquired core technologies, licensed technologies, IPR&D, customer relationships, and trade names. The cost of all identifiable intangible assets with finite lives is amortized on a straight-line basis over the assets’ respective estimated useful lives.

IPR&D, which also has an indefinite useful life, is reviewed for impairment at least annually, or more frequently if an event occurs indicating the potential for impairment. The IPR&D impairment test requires the Company to assess the fair value of the asset as compared to its carrying value and record an impairment charge if the carrying value exceeds the fair value. The Company performed its annual impairment test of its IPR&D in the second fiscal quarter of 2012 and recorded $21.4 million in impairment charges within research and development expenses in the consolidated statements of income. Resources previously assigned to the research project were re-directed with no plans for additional investments to be made to the project in the foreseeable future.

The Company regularly performs reviews to determine if any event has occurred that may indicate its intangible assets with finite useful lives and other long-lived assets are potentially impaired. If indicators of impairment exist, the Company performs an impairment test to assess the recoverability of the affected assets by determining whether the carrying amount of such assets exceeds the undiscounted expected future cash flows. If the affected assets are not recoverable, the Company estimates the fair value of the assets and records an impairment loss if the carrying value of the assets exceeds the fair value. Factors that would indicate potential impairment include a significant decline in the Company’s stock price and market capitalization compared to its net book value, significant changes in the ability of a particular asset to generate positive cash flows, and significant changes in the Company’s strategic business objectives and utilization of a particular asset. The Company performed quarterly reviews of its intangible assets with finite useful lives and other long-lived assets and noted no indications of impairment for the year ended December 30, 2012.

Reserve for Product Warranties

The Company generally provides a one-year warranty on instruments. Additionally, the Company provides a warranty on its consumables through the expiration date, which generally ranges from six to twelve months after the manufacture date. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses based on historical experience as well as anticipated product performance. The Company periodically reviews the adequacy of its warranty reserve and adjusts, if necessary, the warranty accrual based on actual experience and estimated costs to be incurred. Warranty expense is recorded as a component of cost of product revenue.

Revenue Recognition

The Company’s revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of instrumentation and consumables used in genetic analysis. Service and other revenue primarily consists of revenue received for performing genotyping and sequencing services, instrument service contract sales, and amounts earned under research agreements with government grants, which are recognized in the period during which the related costs are incurred.
 
The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price to the buyer is fixed or determinable, and collectibility is reasonably assured. In instances where final acceptance of the product or system is required, revenue is deferred until all the acceptance criteria have been met. All revenue is recorded net of any discounts.

 Revenue from product sales is recognized generally upon transfer of title to the customer, provided that no significant obligations remain and collection of the receivable is reasonably assured. Revenue from instrument service contracts is recognized as the services are rendered, typically evenly over the contract term. Revenue from genotyping and sequencing services is recognized when earned, which is generally at the time the genotyping or sequencing analysis data is made available to the customer or agreed upon milestones are reached.
In order to assess whether the price is fixed or determinable, the Company evaluates whether refund rights exist. If there are refund rights or payment terms based on future performance, the Company defers revenue recognition until the price becomes fixed or determinable. The Company assesses collectibility based on a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If the Company determines that collection of a payment is not reasonably assured, revenue recognition is deferred until receipt of payment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company regularly enters into contracts where revenue is derived from multiple deliverables including any mix of products or services. These products or services are generally delivered within a short time frame, approximately three to six months, after the contract execution date. Revenue recognition for contracts with multiple deliverables is based on the individual units of accounting determined to exist in the contract. A delivered item is considered a separate unit of accounting when the delivered item has value to the customer 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. Consideration is allocated at the inception of the contract to all deliverables based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (VSOE) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence exists, the Company uses its best estimate of the selling price for the deliverable.
In order to establish VSOE of selling price, the Company must regularly sell the product or service on a standalone basis with a substantial majority priced within a relatively narrow range. VSOE of selling price is usually the midpoint of that range. If there are not a sufficient number of standalone sales and VSOE of selling price cannot be determined, then the Company considers whether third party evidence can be used to establish selling price. Due to the lack of similar products and services sold by other companies within the industry, the Company has rarely established selling price using third-party evidence. If neither VSOE nor third party evidence of selling price exists, the Company determines its best estimate of selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, the Company relies upon prices set by the Company’s pricing committee adjusted for applicable discounts. The Company recognizes revenue for delivered elements only when it determines there are no uncertainties regarding customer acceptance.
During the fiscal year ended January 1, 2012, the Company completed its Genome Analyzer trade-in program that enabled certain Genome Analyzer customers to trade in their Genome Analyzer and receive a discount on the purchase of a HiSeq 2000. The incentive was limited to customers who had purchased a Genome Analyzer prior to the beginning of the incentive program in early 2010 and was the only significant trade-in program offered by the Company to date. The Company accounted for HiSeq 2000 discounts related to the Genome Analyzer trade-in program as reductions to revenue upon recognition of the HiSeq 2000 sales revenue, which is later than the date the trade-in program was launched.
In certain markets, the Company sells products and provides services to customers through distributors that specialize in life science products. In most sales through distributors, the product is delivered directly to customers. In cases where the product is delivered to a distributor, revenue recognition is deferred until acceptance is received from the distributor, and/or the end-user, if required by the applicable sales contract. The terms of sales transactions through distributors are consistent with the terms of direct sales to customers. These transactions are accounted for in accordance with the Company’s revenue recognition policy described herein.

Shipping and Handling Expenses

Shipping and handling expenses are included in cost of product revenue.

Research and Development

Research and development expenses include personnel expenses, contractor fees, license fees, facilities costs, and utilities. Expenditures relating to research and development are expensed in the period incurred.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs were $7.3 million, $6.8 million, and $6.9 million for the years ended December 30, 2012, January 1, 2012, and January 2, 2011, respectively.

Leases

Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations, the Company records rent expense on a straight-line basis over the term of the lease, which includes the construction build-out period and lease extension periods, if appropriate. The difference between rent payments and straight-line rent expense is recorded as deferred rent in accrued liabilities and other long-term liabilities. Landlord allowances are amortized on a straight-

57

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

line basis over the lease term as a reduction to rent expense. The Company capitalizes leasehold improvements and amortizes them over the shorter of the lease term or their expected useful lives.

In 2012, the Company completed the relocation of its headquarters to another facility in San Diego, California. Headquarter relocation expenses recorded in years ended December 30, 2012 and January 1, 2012 primarily consisted of accelerated depreciation expense, impairment of assets, additional rent expense during the transition period when both the new and former headquarter facilities are occupied, moving expenses, and cease-use losses. The Company recorded accelerated depreciation expense for leasehold improvements at its former headquarter facility based on the reassessed useful lives of less than a year. The Company recorded cease-use losses and the corresponding facility exit obligation upon vacating certain buildings of its former headquarters, calculated as the present value of the remaining lease obligation offset by estimated sublease rental receipts during the remaining lease period, adjusted for deferred items and estimated lease incentives. The key assumptions used in the calculation include the amount and timing of estimated sublease rental receipts, and the risk-adjusted discount rate.

Restructuring Charges

During the fourth quarter of the year ended January 1, 2012, the Company announced and executed a restructuring plan, to reduce the Company’s workforce and to consolidate certain facilities. The Company measured and accrued the liabilities associated with employee separation costs at fair value as of the date the plan was announced and terminations were communicated to employees, which primarily included severance pay and other separation costs such as outplacement services and benefits.

The fair value measurement of restructuring related liabilities requires certain assumptions and estimates to be made by the Company, such as the retention period of certain employees, the timing and amount of sublease income on properties to be vacated, and the operating costs to be paid until lease termination. It is the Company’s policy to use the best estimates based on facts and circumstances available at the time of measurement, review the assumptions and estimates periodically, and adjust the liabilities when necessary.

Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date.

Deferred tax assets are regularly assessed to determine the likelihood they will be recovered from future taxable income. A valuation allowance is established when the Company believes it is more likely than not the future realization of all or some of a deferred tax asset will not be achieved. In evaluating the ability to recover deferred tax assets within the jurisdiction which they arise the Company considers all available positive and negative evidence. Factors reviewed include the cumulative pre-tax book income for the past three years, scheduled reversals of deferred tax liabilities, history of earnings and reliable forecasting, projections of pre-tax book income over the foreseeable future, and the impact of any feasible and prudent tax planning strategies.

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.

The Company recognizes the impact of a tax position in the 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 in income tax expense.


58

Functional Currency

The U.S. dollar is the functional currency of the Company’s international operations. The Company remeasures its foreign subsidiaries’ assets and liabilities and revenue and expense accounts related to monetary assets and liabilities to the U.S. dollar and records the net gains or losses resulting from remeasurement in other (expense) income, net in the consolidated statements of income. During the years ended December 30, 2012 and January 1, 2012, the Company recorded $2.2 million net gain and $2.0 million net loss from remeasurement, respectively. Gains and losses related to remeasurement were immaterial for the year ended January 2, 2011.

Derivatives

The Company is exposed to foreign exchange rate risks in the normal course of business. To manage a portion of the accounting exposure resulting from changes in foreign currency exchange rates, the Company enters into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the U.S. dollar. These foreign exchange contracts are carried at fair value and are not designated as hedging instruments. Changes in the value of the derivatives are recognized in other (expense) income, net, in the consolidated statements of income in the respective periods, along with an offsetting remeasurement gain or loss on the underlying foreign currency denominated assets or liabilities.

As of December 30, 2012, the Company had foreign exchange forward contracts in place to hedge exposures in the euro, Japanese yen, and Australian dollar. As of December 30, 2012 and January 1, 2012, the total notional amount of outstanding forward contracts in place for foreign currency purchases was $51.2 million and $25.5 million, respectively. Non-designated foreign exchange forward contract related gain was $1.2 million for the year ended December 30, 2012 and immaterial for the years ended January 1, 2012 and January 2, 2011.

Share-Based Compensation

The Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of stock options granted and stock purchases under the Employee Stock Purchase Plan (ESPP). This model incorporates various assumptions including expected volatility, expected term of an award, expected dividends, and the risk-free interest rates. The Company determines the expected volatility by equally weighing the historical and implied volatility of the Company’s common stock. The historical volatility of the Company’s common stock over the most recent period is generally commensurate with the estimated expected term of the Company’s stock awards, adjusted for the impact of unusual fluctuations not reasonably expected to recur and other relevant factors. The implied volatility is calculated from the implied market volatility of exchange-traded call options on the Company’s common stock. The expected term of an award is based on historical forfeiture experience, exercise activity, and on the terms and conditions of the stock awards. The expected dividend yield is determined to be 0% given that the Company has never declared or paid cash dividends on its common stock and does not anticipate paying such cash dividends. The risk-free interest rate is based upon U.S. Treasury securities with remaining terms similar to the expected term of the share-based awards. The fair value of restricted stock units granted is based on the market price of the Company’s common stock on the date of grant. The Company recognizes the fair value of share-based compensation on a straight-line basis over the requisite service periods of the awards.

Net Income per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the reporting period increased to include dilutive potential common shares calculated using the treasury stock method. Diluted net income per share reflects the potential dilution from outstanding stock options, restricted stock units, ESPP, warrants, shares subject to forfeiture, and convertible senior notes. Under the treasury stock method, convertible senior notes will have a dilutive impact when the average market price of the Company’s common stock is above the applicable conversion price of the respective notes. In addition, the following amounts are assumed to be used to repurchase shares: the amount that must be paid to exercise stock options and warrants and purchase shares under the ESPP; the average amount of compensation expense for future services that the Company has not yet recognized for stock options, restricted stock units, ESPP, and shares subject to forfeiture; and the amount of tax benefits that will be recorded in additional paid-in capital when the expenses related to respective awards become deductible.

As of December 30, 2012 the Company had 59 available-for-sale securities in a gross unrealized loss position, all of which had been in such position for less than twelve months. There were no impairments considered other-than-temporary as it is more likely than not the Company will hold the securities until maturity or a recovery of the cost basis. The following table shows the fair values and the gross unrealized losses of the Company’s available-for- sale securities that were in an unrealized loss position as of December 30, 2012 and January 1, 2012 aggregated by investment category (in thousands):

Cost-Method Investments

As of December 30, 2012 and January 1, 2012, the aggregate carrying amounts of the Company’s cost-method investments in non-publicly traded companies were $56.3 million and $45.3 million, respectively. The Company’s cost-method investments are assessed for impairment quarterly. The Company does not estimate the fair value of cost-method investments if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investments. The Company includes cost-method investments in other long term assets in the consolidated balance sheets.

During the fourth quarter of 2012, the Company sold its minority ownership interest in deCODE Genetics, Inc., an Icelandic company that focuses on the genetic studies of human disease, to Amgen Inc., a biotechnology medicines company based in the U.S.  Gross proceeds received were $50.8 million, resulting in a gain of $48.6 million. Also during the fourth quarter of 2012, the Company received $6.0 million from an investee in principal payment of a loan that was previously impaired, and recorded the recovered funds in interest income in the consolidated statements of income.

As a result of its impairment analysis performed in the fourth quarter of 2012, the Company determined that a cost-method investment was other-than-temporarily impaired and recorded an impairment loss of $2.7 million. This determination was based upon operational performance trends coupled with uncertainty regarding the entity’s ability to obtain additional funding in a required timeframe for the entity to continue operations.

No impairment losses were recorded during the year ended January 1, 2012. In the year ended January 2, 2011, the Company determined that a $6.0 million cost-method investment and a related $6.8 million note receivable with interest receivable of $0.4 million were below carrying value and the impairment was other-than-temporary. As a result, the Company recorded an impairment charge of $13.2 million in cost-method investment gain (loss), net in the consolidated statements of income for the year ended January 2, 2011.

4.Acquisitions

BlueGnome

On September 19, 2012, the Company announced the acquisition of BlueGnome Ltd. (BlueGnome), a provider of cytogenetics and in vitro fertilization screening products. Total consideration for the acquisition was $95.5 million, which included $88.0 million in initial cash payments and $7.5 million in fair value of contingent cash consideration of up to $20.0 million based on the achievement of certain revenue based milestones by December 28, 2014.
The Company estimated the fair value of contingent cash consideration using a probability weighted discounted cash flow approach, a Level 3 measurement based on unobservable inputs that are supported by little or no market activity and reflect the Company’s own assumptions in measuring fair value. The Company used a discount rate of 30% in the assessment of the acquisition date fair value for the contingent cash consideration. Future changes in significant inputs such as the discount rate and estimated probabilities of milestone achievements could have a significant effect on the fair value of the contingent consideration.

63

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


In conjunction with the purchase transaction, the Company also agreed to pay up to $20.0 million to BlueGnome shareholders contingent upon the retention of certain key employees and certain other criteria. Such contingent payments are recognized as contingent compensation expense over the retention period through December 28, 2014.

The Company allocated approximately $11.2 million of the total consideration to tangible assets, net of liabilities, and $48.9 million to identified intangible assets, including additional developed technologies of $25.0 million, customer relationships of $16.8 million, and a trade name of $7.1 million with average useful lives of seven, five, and ten years, respectively. The Company also recorded a $12.1 million deferred tax liability to reflect the tax impact of certain identified intangible assets, the amortization expenses for which are not tax deductible. The Company recorded the excess consideration of approximately $47.5 million as goodwill.

Prior Acquisitions

On January 10, 2011, the Company acquired Epicentre Technologies Corporation (Epicentre), a provider of nucleic acid sample preparation reagents and specialty enzymes used in sequencing and microarray applications. Total consideration for the acquisition was $71.4 million, which included $59.4 million in net cash payments, $4.6 million in the fair value of contingent consideration settled in stock that is subject to forfeiture if certain non-revenue based milestones are not met, and $7.4 million in the fair value of contingent cash consideration of up to $15.0 million based on the achievement of certain revenue based milestones by January 10, 2013.
The Company estimated the fair value of contingent stock consideration based on the closing price of its common stock as of the acquisition date. Approximately 229,000 shares of common stock were issued to Epicentre shareholders in connection with the acquisition, which shares are subject to forfeiture if certain non-revenue-based milestones are not met. One third of these shares issued with an assessed fair value of $4.6 million were determined to be part of the purchase price. The remaining shares with an assessed fair value of $10.1 million were determined to be compensation for post-acquisition service, the cost of which will be recognized as contingent compensation expense over a period of two years in research and development expense and selling, general and administrative expense.
The Company estimated the fair value of contingent cash consideration using a probability weighted discounted cash flow approach, a Level 3 measurement based on unobservable inputs that are supported by little or no market activity and reflects the Company’s own assumptions in measuring fair value. The Company used a discount rate of 21% in the assessment of the acquisition date fair value for the contingent cash consideration.
The Company allocated $0.9 million of the total consideration to tangible assets, net of liabilities, and $26.9 million to identified intangible assets, including additional developed technologies of $23.3 million, a trade name of $2.5 million, and customer relationships of $1.1 million, with weighted average useful lives of approximately nine, ten, and three years, respectively. The Company recorded the excess consideration of $43.6 million as goodwill.

On July 28, 2010, the Company completed an acquisition of another privately-held, development stage entity. Total consideration for the acquisition was $22.0 million. As a result of this transaction, the Company recorded an IPR&D asset of $21.4 million in intangible assets. In determining the fair value of the IPR&D, various factors were considered, such as future revenue contributions, additional research and development costs to be incurred, and contributory asset charges. The fair value of the IPR&D was calculated using an income approach, and the rate used to discount net future cash flows to their present values was based on a risk-adjusted rate of return of approximately 28%. Significant factors considered in the calculation of the rate of return include the weighted average cost of capital, the weighted average return on assets, the internal rate of return, as well as the risks inherent in the development process for development-stage entities of similar sizes.

On April 30, 2010, the Company completed the acquisition of Helixis, Inc. (Helixis), a company developing a high-performance, low-cost, real time PCR system used for nucleic acid analysis. Total consideration for the acquisition was $86.7 million, including $70.0 million in net cash payments and $14.1 million for the fair value of contingent consideration payments that could range from $0 to $35 million based on the achievement of certain revenue-based milestones by December 31, 2011. The Company allocated $2.3 million of the consideration to tangible assets, net of liabilities, and $28.0 million to identified intangible assets that will be amortized over a useful life of ten years. The Company also recorded a $10.7 million deferred tax liability to reflect the tax impact of the identified intangible assets, the amortization expenses for which are not tax deductible and an $8.7 million deferred tax asset which primarily relates to acquired net operating loss carryforwards. The Company recorded the excess consideration of $58.4 million as goodwill.

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


Prior to the acquisition, the Company had an equity interest in Helixis with a cost basis of $2.0 million that was accounted for under the cost-method of accounting. The Company recognized a gain of $2.9 million, which was included in other (expense) income, net, in its consolidated statement of income as a result of revaluing the Company’s equity interest in Helixis on the acquisition date.

In addition, the Company agreed to pay the former shareholders of another development stage company acquired in 2008 a certain amount of contingent cash consideration based on the achievement of certain product-related and employment-related milestones. In accordance with the applicable accounting guidance effective at the time, such consideration was accounted for as additional elements of the cost of acquisition, resulting in additional IPR&D charges in the years ended January 1, 2012 and January 2, 2011 when the contingencies were resolved beyond a reasonable doubt and the considerations were issued or became issuable.

The Company holds available-for-sale securities that consist of highly liquid, investment grade debt securities. The Company determines the fair value of its debt security holdings based on pricing from a service provider. The service provider values the securities based on “consensus pricing,” using market prices from a variety of industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets or liabilities (Level 1 inputs) or pricing determined using inputs that are observable either directly or indirectly (Level 2 inputs), such as quoted prices for similar assets or liabilities, yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. The Company’s deferred compensation plan assets consist primarily of mutual funds. See note “14. Employee Benefit Plans” for additional information about our deferred compensation plan. The Company performs certain procedures to corroborate the fair value of its holdings, including comparing prices obtained from service providers to prices obtained from other reliable sources.

The Company reassesses the fair value of contingent consideration to be settled in cash related to acquisitions on a quarterly basis using the income approach. This is a Level 3 measurement. Significant assumptions used in the measurement include probabilities of achieving the remaining milestones and the discount rates, which depend on the milestone risk profiles. Due to changes in the estimated payments and a shorter discounting period, the fair value of the contingent consideration

7.Convertible Senior Notes

0.25% Convertible Senior Notes due 2016

In 2011, the Company issued $920.0 million aggregate principal amount of 0.25% convertible senior notes due 2016 (2016 Notes) in an offering conducted in accordance with Rule 144A under the Securities Act of 1933, as amended. The 2016 Notes were issued at 98.25% of par value. Debt issuance costs of approximately $0.4 million were primarily comprised of legal, accounting, and other professional fees, the majority of which were recorded in other noncurrent assets and are being amortized to interest expense over the five-year term of the 2016 Notes.

The 2016 Notes will be convertible into cash, shares of common stock, or a combination of cash and shares of common stock, at the Company’s election, based on an initial conversion rate, subject to adjustment, of 11.9687 shares per $1,000 principal amount of the 2016 Notes (which represents an initial conversion price of approximately $83.55 per share), only in the following circumstances and to the following extent: (1) during the five business-day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price per 2016 Note for each day of such measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such day; (2) during any calendar quarter (and only during that quarter) after the calendar quarter ending March 31, 2011, if the last reported sale price of the Company's common stock for 20 or more trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; (3) upon the occurrence of specified events described in the indenture for the 2016 Notes; and (4) at any time on or after December 15, 2015 through the second scheduled trading day immediately preceding the maturity date.

As noted in the indenture for the 2016 Notes, it is the Company’s intent and policy to settle conversions through combination settlement, which essentially involves repayment of an amount of cash equal to the “principal portion” and delivery of the “share amount” in excess of the conversion value over the principal portion in shares of common stock. In general, for each $1,000 in principal, the “principal portion” of cash upon settlement is defined as the lesser of $1,000, and the conversion value during the 20-day observation period as described in the indenture for the 2016 Notes. The conversion value is the sum of the daily conversion value which is the product of the effective conversion rate divided by 20 days and the daily volume weighted average price (“VWAP”) of the Company’s common stock. The “share amount” is the cumulative “daily share amount” during the observation period, which is calculated by dividing the daily VWAP into the difference between the daily conversion value (i.e., conversion rate x daily VWAP) and $1,000.

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


The Company pays 0.25% interest per annum on the principal amount of the 2016 Notes semiannually in arrears in cash on March 15 and September 15 of each year. The Company paid $2.3 million in interest payments during the year ended December 30, 2012. The 2016 Notes mature on March 15, 2016. If a designated event, as defined in the indenture for the 2016 Notes, such as an acquisition, merger, or liquidation, occurs prior to the maturity date, subject to certain limitations, holders of the 2016 Notes may require the Company to repurchase all or a portion of their 2016 Notes for cash at a repurchase price equal to 100% of the principal amount of the 2016 Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.

The Company accounts separately for the liability and equity components of the 2016 Notes in accordance with authoritative guidance for convertible debt instruments that may be settled in cash upon conversion. The guidance requires the carrying amount of the liability component to be estimated by measuring the fair value of a similar liability that does not have an associated conversion feature. Because the Company has no outstanding non-convertible public debt, the Company determined that senior, unsecured corporate bonds traded on the market represent a similar liability to the convertible senior notes without the conversion option. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and with similar maturity, the Company estimated the implied interest rate of its 2016 Notes to be 4.5%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the 2016 Notes, which resulted in a fair value of the liability component of $748.5 million upon issuance, calculated as the present value of implied future payments based on the $920.0 million aggregate principal amount. The $155.4 million difference between the cash proceeds of $903.9 million and the estimated fair value of the liability component was recorded in additional paid-in capital as the 2016 Notes are not considered currently redeemable at the balance sheet date.

If the 2016 Notes were converted as of December 30, 2012, the if-converted value would not exceed the principal amount. As a policy election under applicable guidance related to the calculation of diluted net income per share, the Company elected the combination settlement method as its stated settlement policy and applied the treasury stock method. The 2016 Notes had an anti-dilutive effect for the years ended December 30, 2012 and January 1, 2012.

0.625% Convertible Senior Notes due 2014

In 2007, the Company issued $400.0 million principal amount of 0.625% convertible senior notes due 2014 (2014 Notes). The Company pays 0.625% interest per annum on the principal amount of the 2014 Notes, payable semi-annually in arrears in cash on February 15 and August 15 of each year. The 2014 Notes mature on February 15, 2014. The effective interest rate of the liability component was estimated to be 8.3%.

The Company entered into hedge transactions concurrently with the issuance of the 2014 Notes under which the Company is entitled to purchase up to approximately 18,322,000 shares of the Company’s common stock at a strike price of approximately $21.83 per share, subject to adjustment. The convertible note hedge transactions had the effect of reducing dilution to the Company’s stockholders upon conversion of the 2014 Notes. Also concurrently with the issuance of the 2014 Notes, the Company sold to the hedge counterparties warrants exercisable, on a cashless basis, for up to approximately 18,322,000 shares of the Company’s common stock at a strike price of $31.435 per share, subject to adjustment. The proceeds from these warrants partially offset the cost to the Company of the convertible note hedge transactions.

The 2014 Notes became convertible into cash and shares of the Company’s common stock in various prior periods and became convertible again from April 1, 2012 through, and including, December 30, 2012. There were no conversions of the 2014 Notes during the year ended December 30, 2012. During the year ended January 1, 2012, the principal amount of all 2014 Notes converted was repaid with cash and the excess of the conversion value over the principal amount was paid in shares of common stock. The equity dilution resulting from the issuance of common stock related to the conversion of the 2014 Notes was offset by repurchase of the same amount of shares under the convertible note hedge transactions, which were automatically exercised in accordance with their terms at the time of each such conversion. The balance of the convertible note hedge transactions with respect to approximately $40.1 million principal amount of the 2014 Notes (which are convertible into up to 1,838,000 shares of the Company’s common stock) remained in place as of December 30, 2012. The warrants were not affected by the early conversions of the 2014 Notes and, as a result, warrants covering up to approximately 18,322,000 shares of common stock remained outstanding as of December 30, 2012.

As a result of the conversions during the year ended January 1, 2012, the Company recorded losses on extinguishment of debt calculated as the difference between the estimated fair value of the debt and the carrying value of the notes as of the settlement dates. To measure the fair value of the converted notes as of the settlement dates, the applicable interest rates were estimated using Level 2 observable inputs and applied to the converted notes using the same methodology as in the issuance date valuation. If the 2014 Notes were converted as of December 30, 2012, the if-converted value would exceed the principal amount by $60.0 million.

The following table summarizes information about the equity and liability components of the 2014 and 2016 Notes (dollars in thousands). The fair values of the respective notes outstanding were measured based on quoted market prices.

There is no set number of shares reserved for issuance under the New Hire Stock and Incentive Plan.

Stock Options

Stock options granted at the time of hire primarily vest over a four or five-year period, with 20% or 25% of options vesting on the first anniversary of the grant date and the remaining options vesting monthly over the remaining vesting period. Stock options granted subsequent to hiring primarily vest monthly over a four or five-year period.Each grant of options has a

At December 30, 2012, outstanding options to purchase approximately 6,725,000 shares were exercisable with a weighted average per share exercise price of $28.49. The weighted average remaining life of options outstanding and exercisable is 5.5 years and 5.0 years, respectively, as of December 30, 2012.

The aggregate intrinsic value of options outstanding and options exercisable as of December 30, 2012 was $207.0 million and $185.9 million, respectively. Aggregate intrinsic value represents the product of the number of options outstanding multiplied by the difference between the Company’s closing stock price per share on the last trading day of the fiscal period, which was $54.75 as of December 28, 2012, and the exercise price. Total intrinsic value of options exercised was $60.6 million, $136.5 million, and $156.9 million for the years ended December 30, 2012, January 1, 2012, and January 2, 2011, respectively. Total fair value of options vested was $31.9 million, $49.5 million, and $47.3 million for the years ended December 30, 2012, January 1, 2012, and January 2, 2011, respectively.

Restricted Stock

The Company issues restricted stock units (RSUs) and restricted stock awards (RSAs). The Company grants RSUs pursuant to its 2005 Stock and Incentive Plan. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company’s common stock. For grants to new hires prior to July 2011 and for grants to existing employees, RSUs generally vest 15% on the first anniversary of the grant date, 20% on the second anniversary of the grant date, 30% on the third anniversary of the grant date, and 35% on the fourth anniversary of the grant date. For grants to new hires subsequent to July 2011, RSUs generally vest over a four-year period with equal vesting on anniversaries of the grant date. The Company satisfies RSU vesting through the issuance of new shares. The Company also issues RSAs that are released based on service related vesting conditions. RSAs may be issued from the Company’s treasury stock or granted pursuant to the Company’s 2005 Stock and Incentive Plan.

Performance Stock Units

In March 2012, the Company’s Compensation Committee of the Company’s Board of Directors approved changes to the Company’s long-term equity incentive program for executive officers and approved the issuance of certain performance stock units at the end of a three-year performance period. The number of shares issuable will range from 50% and 150% of the shares approved in the award based on the Company’s performance relative to specified earnings per share targets at the end of the three-year performance period. A total of 587,000 shares were outstanding as of December 30, 2012 with a weighted-average grant-date fair value of $49.64, which represents the fair market value of one share of the Company’s common stock on the grant date.

Employee Stock Purchase Plan

A total of 15,467,000 shares of the Company’s common stock have been reserved for issuance under its 2000 Employee Stock Purchase Plan, or ESPP. The ESPP permits eligible employees to purchase common stock at a discount, but only through payroll deductions, during defined offering periods. The price at which stock is purchased under the ESPP is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. The initial offering period commenced in July 2000.

The ESPP provides for annual increases of shares available for issuance by the lesser of 3% of the number of outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, 3,000,000 shares, or such lesser amount as determined by the Company’s board of directors. Shares totaling approximately 328,000, 328,000, and 373,000 were issued under the ESPP during the years ended December 30, 2012, January 1, 2012, and January 2, 2011, respectively. As of December 30, 2012 and January 1, 2012, there were approximately 15,406,000 shares and 15,734,000 shares available for issuance under the ESPP, respectively.

Warrants

As of December 30, 2012, warrants exercisable, on a cashless basis, for up to approximately 18,322,000 shares of common stock were outstanding with an exercise price of $31.435. These warrants were sold to counterparties to the Company’s convertible note hedge transactions in connection with the offering of the Company’s 2014 Notes, with the proceeds of such warrants used by the Company to partially offset the cost of such hedging transactions. All outstanding warrants expire in equal installments during the 40 consecutive scheduled trading days beginning on May 16, 2014.

During the year ended January 1, 2012, the remaining warrants assumed by the Company in a prior acquisition to purchase approximately 505,000 shares of the Company’s common stock were exercised, resulting in cash proceeds to the Company of approximately $5.5 million.

Share Repurchases

On April 18, 2012, the Company’s Board of Directors authorized a $250 million stock repurchase program to be effected via a combination of Rule 10b5-1 and discretionary share repurchase programs. During the year ended December 30, 2012, the Company repurchased approximately 1,860,000 shares for $82.5 million.

In August 2011, the Company’s board of directors authorized a $100 million discretionary repurchase program. During the year ended January 1, 2012, the Company utilized the authorized amount in its entirety and repurchased approximately 1,894,000 shares under this program.

Concurrently with the issuance of the Company’s 2016 Notes in 2011, approximately 4,891,000 shares were repurchased for $314.3 million.

In July 2010, the Company’s board of directors authorized a $200 million stock repurchase program, with $100 million allocated to repurchasing Company common stock under a 10b5-1 plan over a twelve month period and $100 million allocated to repurchasing Company common stock at management’s discretion during open trading windows. During the year ended January 1, 2012, the Company repurchased approximately 2,438,000 shares for $156.0 million. The authorized repurchase amount had been utilized completely as of January 1, 2012.

Stockholder Rights Plan

In connection with the unsolicited tender offer by Roche (refer to note “12. Unsolicited Tender Offer”), on January 25, 2012, the Company’s Board of Directors declared a dividend of one preferred share purchase right (Right) for each outstanding share of the Company’s common stock. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of the Company’s Series A Junior Participating Preferred Stock, par value $0.01 per share (Preferred Shares), at a price of $275.00 per one thousandth of a Preferred Share, subject to adjustment. The Rights will not be exercisable until such time, if ever, that the Board of Directors determines to eliminate its deferral of the date on which separate Rights certificates are issued and the Rights trade separately from the Company’s common stock (Distribution Date). If a person or group (triggering party) acquires 15% or more of the Company’s outstanding common stock, each Right will entitle holders other than the triggering party to purchase, at the exercise price of the Right, a number of shares of common stock having a market value of two times the exercise price of the Right. If the Company is acquired in a merger or other business combination transaction after a person acquires 15% or more of the Company’s common stock, each Right will entitle holders other than the triggering party to purchase, at the Right’s then-current exercise price, a number of common shares of the acquiring company that at the time of such transaction have a market value of two times the exercise price of the Right. The Board of Directors will be entitled to redeem the Rights at a price of $0.001 per Right at any time before the Distribution Date. The Board of Directors will also be entitled to exchange the Rights at an exchange ratio per Right of one share of common stock after any person acquires beneficial ownership of 15% or more of the Company’s outstanding common stock, and prior to the acquisition of 50% or more of the Company’s outstanding common stock. The Rights will expire on January 26, 2017.

On May 3, 2001, the board of directors of the Company declared a dividend of one preferred share purchase right (Right) for each outstanding share of common stock of the Company. The dividend was payable on May 14, 2001 to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one unit consisting of one thousandth of a share of its Series A Junior Participating Preferred Stock at a price of $100 per unit. The Rights will be exercisable if a person or group hereafter acquires beneficial ownership of 15% or more of the outstanding common stock of the Company or announces an offer for 15% or more of the outstanding common stock. If a person or group acquires 15% or

74

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

more of the outstanding common stock of the Company, each Right will entitle its holder to purchase, at the exercise price of the Right, a number of shares of common stock having a market value of two times the exercise price of the Right. If the Company is acquired in a merger or other business combination transaction after a person acquires 15% or more of the Company’s common stock, each Right will entitle its holder to purchase, at the Right’s then-current exercise price, a number of common shares of the acquiring company which at the time of such transaction have a market value of two times the exercise price of the Right. The board of directors will be entitled to redeem the Rights at a price of $0.01 per Right at any time before any such person acquires beneficial ownership of 15% or more of the outstanding common stock. The Rights expired on May 14, 2011.

11.Legal Proceedings

The Company is involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. In connection with these matters, the Company assesses, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. During the year ended December 30, 2012, the Company recorded a legal contingency loss of $3.0 million in aggregate within cost of product revenue. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. The Company regularly reviews its outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures. The amount of ultimate loss may differ from these estimates. Each matter presents its own unique circumstances, and prior litigation does not necessarily provide a reliable basis on which to predict the outcome, or range of outcomes, in any individual proceeding. Because of the uncertainties related to the occurrence, amount, and range of loss on any pending litigation or claim, management is currently unable to predict their ultimate outcome, and, with respect to any pending litigation or claim where no liability has been accrued, to make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. In the event that opposing litigants in outstanding litigations or claims ultimately succeed at trial and any subsequent appeals on their claims, any potential loss or charges in excess of any established accruals, individually or in the aggregate, could have a material adverse effect on the Company’s business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods.

On November 24, 2010, Syntrix Biosystems, Inc. filed suit against the Company in the United States District Court for the Western District of Washington at Tacoma (Case No. C10-5870-BHS) alleging that the Company willfully infringed U.S. Patent No. 6,951,682 by selling its BeadChip array products, and that the Company misappropriated Syntrix’s trade secrets. Fact and expert discovery is complete in the case. In November and December 2012, the Company filed motions for summary judgment that the patent is not infringed and is invalid, and that Syntrix’s trade secrets claims are barred by various statutes of limitation. Syntrix filed a motion for summary judgment that the patent is valid. On January 30, 2013, the court granted the Company’s motion for summary judgment on Syntrix’s trade secret claims, and dismissed those claims from the case. The court denied Syntrix’s motion for summary judgment on validity, and denied the Company’s motion for summary judgment for non-infringement and invalidity. A trial is scheduled to begin on February 26, 2013.
The Company has thoroughly investigated Syntrix’s claims and believes the claims are without merit. While the Company believes there is no legal basis for its alleged liability, the Company cannot estimate the possible loss or range of possible loss as there are significant legal and factual issues to be resolved. For example, each party has filed motions seeking to exclude portions of the other party’s expert testimony and to preclude the other party from introducing certain other evidence at trial. In addition to post-trial briefing, the parties would likely engage in appellate motion practice, the result of which is also unpredictable and could significantly affect the outcome of the case.

12.Unsolicited Tender Offer

On January 27, 2012, CKH Acquisition Corporation and Roche Holding Ltd. (together, “Roche”) commenced an unsolicited tender offer (Offer) to purchase all outstanding shares of the Company’s common stock for $44.50 per share. As more fully described in the Company’s Solicitation/Recommendation on Schedule 14D-9 filed with the SEC on February 7, 2012 in response to the Offer, the Company’s Board of Directors unanimously recommended that the Company’s stockholders reject the Offer and not tender their shares to Roche for purchase.

On March 28, 2012, Roche revised the Offer to purchase all outstanding shares of the Company’s common stock for $51.00 per share. As more fully described in the Amendment No. 11 to Solicitation/Recommendation on Schedule 14D-9 filed

75

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

with the SEC on April 2, 2012 in response to the revised Offer, the Company’s Board of Directors unanimously recommended that the Company’s stockholders reject the Roche offer and not tender their shares to Roche for purchase. The Offer expired, without being extended, on April 20, 2012.

During the year ended December 30, 2012, the Company recorded $23.1 million in expenses in relation to the Offer, such expenses consisting primarily of legal, advisory, proxy solicitation, and other professional services fees.

A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. Based on the available evidence as of December 30, 2012, the Company was not able to conclude it is more likely than not certain U.S. deferred tax assets will be realized. Therefore, the Company recorded a valuation allowance of $1.8 million against certain U.S. deferred tax assets.

As of December 30, 2012, the Company had net operating loss carryforwards for federal and state tax purposes of $16.8 million and $117.8 million, respectively, which will begin to expire in 2020 and 2015, respectively. In addition, the Company also had state research and development tax credit carryforwards of $39.7 million, which will begin to expire in 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Pursuant to Section 382 and 383 of the Internal Revenue Code, utilization of the Company’s net operating loss and credits may be subject to annual limitations in the event of any significant future changes in its ownership structure. These annual limitations may result in the expiration of net operating losses and credits prior to utilization. The deferred tax assets as of December 30, 2012 are net of any previous limitations due to Section 382 and 383.

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. During the year ended December 30, 2012, the Company realized $17.0 million of such excess tax benefits, and accordingly recorded a corresponding credit to additional paid in capital. As of December 30, 2012, the Company has $9.8 million of unrealized excess tax benefits associated with share-based compensation. These tax benefits will be accounted for as a credit to additional paid-in capital, if and when realized, rather than a reduction of the provision for income taxes.

The Company’s manufacturing operations in Singapore operate under various tax holidays and incentives that begin to expire in 2018. For the year ended December 30, 2012, these tax holidays and incentives resulted in an approximate $10.2 million decrease to the provision for income taxes and an increase to net income per diluted share of $0.08.

It is the Company’s intention to indefinitely reinvest all current and future foreign earnings in order to ensure sufficient working capital and expand existing operations outside the United States. Accordingly, residual U.S. income taxes have not been provided on $185.6 million of undistributed earnings of foreign subsidiaries as of December 30, 2012. In the event the Company was required to repatriate funds from outside of the United States, such repatriation would be subject to local laws, customs, and tax consequences.
The following table summarizes the gross amount of the Company’s uncertain tax positions (in thousands):

Balance at end of year$37,585
 $28,396
 $22,729

Included in the balance of uncertain tax positions as of December 30, 2012, and January 1, 2012 are $29.9 million and $23.4 million, respectively, of net unrecognized tax benefits that, if recognized, would reduce the Company’s effective income tax rate in future periods.

The Company does not expect its uncertain tax positions to change significantly over the next 12 months. Any interest and penalties related to uncertain tax positions are reflected in the provision for income taxes. The Company recognized expenses of $0.8 million and $1.1 million related to potential interest and penalties on uncertain tax positions during the years ended December 30, 2012 and January 1, 2012, respectively. A minimal amount was recognized in 2010 for potential interest and penalties on uncertain tax positions. The Company recorded a liability for potential interest and penalties of $2.1 million and $1.2 million as of December 30, 2012 and January 1, 2012, respectively. Tax years 1997 to 2012 remain subject to future examination by the major tax jurisdictions in which the Company is subject to tax.

14.Employee Benefit Plans

Retirement Plan

The Company has a 401(k) savings plan covering substantially all of its employees in the United States. Company contributions to the plan are discretionary. During the years ended December 30, 2012, January 1, 2012, and January 2, 2011, the Company made matching contributions of $5.5 million, $5.3 million, and $4.2 million, respectively.

Deferred Compensation Plan

The Company adopted the Illumina, Inc. Deferred Compensation Plan (the Plan) that became effective January 1, 2008. Eligible participants, which include the Company’s senior level employees and members of the board of directors, can contribute up to 80% of their base salary and 100% of all other forms of compensation into the Plan, including bonus, equity awards, commission, and director fees. The Company has agreed to credit the participants’ contributions with earnings that reflect the performance of certain independent investment funds. On a discretionary basis, the Company may also make employer contributions to participant accounts in any amount determined by the Company. The vesting schedules of employer contributions are at the sole discretion of the Compensation Committee. However, all employer contributions shall become 100% vested upon the occurrence of the participant’s disability, death or retirement or a change in control of the Company. The benefits under this plan are unsecured. Participants are generally eligible to receive payment of their vested benefit at the end of their elected deferral period or after termination of their employment with the Company for any reason or at a later date to comply with the restrictions of Section 409A. As of December 30, 2012, no employer contributions were made to the Plan.

In January 2008, the Company also established a rabbi trust for the benefit of the participants under the Plan. In accordance with authoritative guidance related to consolidation of variable interest entities and accounting for deferred compensation arrangements where amounts earned are held in a rabbi trust and invested, the Company has included the assets of the rabbi trust in its consolidated balance sheet since the trust’s inception. As of December 30, 2012 and January 1, 2012, the assets of the trust were $13.6 million and $10.8 million, respectively, and liabilities of the Company were $12.1 million and $9.0 million, respectively. The assets and liabilities are classified as other assets and accrued liabilities, respectively, on the Company’s consolidated balance sheets. Changes in the values of the assets held by the rabbi trust are recorded in other (expense) income, net in the consolidated statement of income, and changes in the values of the deferred compensation liabilities are recorded in cost of sales or operating expenses.

15.Segment Information, Geographic Data, and Significant Customers

The Company is organized in two operating segments: Life Sciences and Diagnostics. Life Sciences operating segment includes all products and services related to the research market, namely the product lines based on the Company’s sequencing, BeadArray, and real-time PCR technologies. The Diagnostics operating segment focuses on the emerging opportunity in molecular diagnostics. During all periods presented, the Diagnostics operating segment had limited activity. Accordingly, the Company’s operating results for both units were reported on an aggregate basis as one reportable segment. The Company will begin reporting in two segments once revenues, operating profit or loss, or assets of the Diagnostics operating segment exceeds 10% of the consolidated amounts.

The Company had revenue in the following regions for the years ended December 30, 2012, January 1, 2012, and January 2, 2011 (in thousands):

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 ActRules 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
We conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of January 3, 2010.December 30, 2012.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of
Illumina, Inc.
We have audited Illumina, Inc.’s internal control over financial reporting as of January 3, 2010,December 30, 2012, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Illumina, Inc.’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, Illumina, Inc. maintained, in all material respects, effective internal control over financial reporting as of January 3, 2010,December 30, 2012, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated balance sheets of Illumina, Inc. as of December 30, 2012 and January 3, 2010 and December 28, 2008,1, 2012, and the related consolidated statements of operations,income, comprehensive income, stockholders’ equity, and cash flows for each of the three fiscal years in the period ended January 3, 2010December 30, 2012 of Illumina, Inc. and our report dated February 26, 201015, 2013 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of
Illumina, Inc.
We have audited the accompanying consolidated balance sheets of Illumina, Inc. as of January 3, 2010 and December 28, 2008, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended January 3, 2010. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule 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 Illumina, Inc., at January 3, 2010 and December 28, 2008, and the consolidated results of its operations and its cash flows for each of the three years in the period ended January 3, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
As discussed in Note 1 to the consolidated financial statements, the Company adopted Financial Accounting Standards Board Staff Position No. APB14-1,Accounting For Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlement)(Codified in FASB ASC Topic 470,Debt Conversions and Other Options)effective as of December 29, 2008 and retroactively adjusted all periods presented in the consolidated financial statements for this change. Also described in Note 1 is the Company’s 2009 change in its method of accounting for revenue recognition with the adoption of amendments to the Financial Accounting Standards Board Accounting Standards Codification resulting from Accounting Standards Update No. 2009-13,Multiple-Deliverable Revenue Arrangements, and Accounting Standards UpdateNo. 2009-14,Certain Revenue Arrangements That Include Software Elements, both adopted effective December 29, 2008.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Illumina, Inc.’s internal control over financial reporting as of January 3, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2010 expressed an unqualified opinion thereon.

ILLUMINA, INC.
Unless the context requires otherwise, references in this report to “Illumina,” “we,” “us,” the “Company,” and “our” refer to Illumina, Inc. and its consolidated subsidiaries.
1.  Organization and Summary of Significant Accounting Policies
Organization and Business
Illumina, Inc. (the Company) is a leading developer, manufacturer and marketer of integrated systems for the analysis of genetic variation and biological function. Using the Company’s proprietary technologies, Illumina provides a comprehensive line of products and services that currently serve the sequencing, genotyping and gene expression markets and the Company expects to enter the market for molecular diagnostics. The Company’s customers include leading genomic research centers, pharmaceutical companies, academic institutions, clinical research organizations and biotechnology companies.
Acquisitions
On August 1, 2008, the Company completed its acquisition of Avantome, Inc., a development-stage company creating a low cost, long-read sequencing technology. At the time of the acquisition, the Company paid $25.8 million in cash, including transaction costs, and recorded a charge of $24.7 million for purchased in-process research and development (IPR&D). As part of the acquisition agreement, Illumina agreed to pay Avantome’s former shareholders up to an additional $35.0 million in contingent cash consideration based on the achievement of certain milestones. For the year ended January 3, 2010, the Company recorded IPR&D of $11.3 million and compensation expense of $3.7 million associated with these milestones. For the year ended December 28, 2008, compensation expense of $1.5 million was recorded associated with these milestones. Compensation expense associated with the Avantome acquisition is included in research and development in the consolidated statements of operations.
On January 26, 2007, the Company completed its acquisition of Solexa, Inc., in astock-for-stock merger transaction. The Company issued 26.2 million shares of its common stock as consideration for this merger. Based on the estimated fair values at the acquisition date, the Company allocated $303.4 million to IPR&D, $62.2 million to tangible assets acquired and liabilities assumed and $24.4 million to intangible assets. The remaining excess of the purchase price over the fair value of net assets acquired of $213.4 million was allocated to goodwill.
Basis of Presentation
The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Fiscal Year
The Company’s fiscal year is 52 or 53 weeks ending the Sunday closest to December 31, with quarters of 13 or 14 weeks ending the Sunday closest to March 31, June 30, and September 30. The year ended January 3, 2010 was 53 weeks; the years ended December 28, 2008 and December 30, 2007 were 52 weeks.
Reclassifications
Certain prior year amounts have been reclassified to conform to current year presentation. During the fourth quarter of 2009, the Company determined that pre-acquisition net operating loss carryforwards of Solexa that were included in goodwill could be utilized by the Company. Therefore, the Company has updated the Consolidated Financial Statements and related disclosures to reclassify $15.3 million from goodwill to


F-7


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
long-term deferred tax assets to correctly reflect the tax effect of Solexa’s pre-acquisition net operating losses that can be utilized by the Company.
Use of Estimates
The preparation of financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
Segment Information
During the first quarter of 2008, the Company reorganized its operating structure into a newly created Life Sciences Business Unit, which includes all products and services that are primarily related to the research market, namely the sequencing, BeadArray, and VeraCode product lines. The Company also created a Diagnostics Business Unit to focus on the emerging opportunity in molecular diagnostics. For the year ended January 3, 2010, the Company had limited activity related to the Diagnostics Business Unit and operating results were reported on an aggregate basis to the chief operating decision maker of the Company, the chief executive officer. Accordingly, the Company operated in one segment for the year ended January 3, 2010. The Company will begin reporting in two segments once revenues, operating profit or loss, or assets of the Diagnostics Business Unit exceed 10% of the consolidated amounts.
Cash Equivalents and Investments
Cash equivalents are comprised of short-term, highly liquid investments with maturities of 90 days or less from the date of purchase.
Short-term investments consist of U.S. Treasury and U.S. government agency securities, municipal notes, corporate notes and bonds and commercial paper. Management classifies short-term investments asavailable-for-sale or trading at the time of purchase and reevaluates such classification as of each balance sheet date. All short-term investments are recorded at estimated fair value. Unrealized gains and losses foravailable-for-sale and trading securities are included in accumulated other comprehensive income, a component of stockholders’ equity, and other income, net, respectively. The Company evaluates its investments to assess whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other than temporary if it is likely that the Company will have to sell the securities before the recovery of their cost basis and it is the Company’s intent to do so. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net in the consolidated statements of operations.
Included in short-term investments are the Company’s auction rate securities and a put option related to the Company’s settlement agreement with UBS that gives the Company the right to sell its auction rate securities to UBS AG (UBS) at par value during the period of June 30, 2010 through July 2, 2012 (the Settlement). These securities had previously been classified as long-term investments; however, they were reclassified to short-term investments in fiscal 2009 as the Company intends to exercise its right to sell the securities back to UBS during the Settlement period. The auction rate securities are classified as trading securities and both the put option and the auction rate securities are recorded at estimated fair value, with unrealized gains and losses, if any, recognized in other income (expense), net on the consolidated statements of operations. See Note 3 for further detailed discussion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Fair Value of Financial Instruments
The carrying amounts of financial instruments such as cash equivalents, foreign cash accounts, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate the related fair values due to the short-term maturities of these instruments. The estimated fair value of the convertible senior notes is determined by using available market information as of the latest trading date prior to the Company’s fiscal year-end provided by a third party financial institution. The par value and fair value of the Company’s convertible notes was $390.0 million and $553.2 million, respectively, at January 3, 2010 and $400.0 million and $473.0 million, respectively, at December 28, 2008.
Accounts Receivable
Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. The Company reviews its exposure to amounts receivable and reserves specific amounts if collectibility is no longer reasonably assured. The Company also reserves a percentage of its trade receivable balance based on collection history and current economic trends that might impact the level of future credit losses. The Company re-evaluates such reserves on a regular basis and adjusts its reserves as needed.
Concentrations of Risk
The Company operates in markets that are highly competitive and rapidly changing. Significant technological changes, shifting customer needs, the emergence of competitive products or services with new capabilities and other factors could negatively impact the Company’s operating results.
The Company is also subject to risks related to its financial instruments including its cash and cash equivalents, investments and accounts receivable. Most of the Company’s cash and cash equivalents as of January 3, 2010 were deposited with financial institutions in the United States. The Company’s investment policy restricts the amount of credit exposure to any one issuer to 5% of the portfolio at the time of purchase and to any one industry sector, as defined by Bloomberg classifications, to 25% of the portfolio at the time of purchase. There is no limit to the percentage of the portfolio that may be maintained in securities issued by the U.S government and money market funds. The Company has historically not experienced significant credit losses from investments and accounts receivable. The Company performs a regular review of customer activity and associated credit risks.
The Company’s products require customized components that currently are available from a limited number of sources. The Company obtains certain key components included in its products from single vendors.
Shipments to customers outside the United States comprised 48%, 51% and 43% of the Company’s revenue for the years ended January 3, 2010, December 28, 2008 and December 30, 2007, respectively. Customers outside the United States represented 46% and 61% of the Company’s net accounts receivable balance as of January 3, 2010 and December 28, 2008, respectively. Sales to territories outside of the United States are generally denominated in U.S. dollars. International sales entail a variety of risks, including currency exchange fluctuations, longer payment cycles and greater difficulty in accounts receivable collection. The Company is also subject to general geopolitical risks, such as political, social and economic instability and changes in diplomatic and trade relations. The risks of international sales are mitigated in part by the extent to which sales are geographically distributed.
Aggregated accounts receivable from one customer comprised more than 10% of gross customer receivable at January 3, 2010.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Inventories
Inventories are stated at the lower of cost (on a first in, first out basis) or market. Inventory includes raw materials and finished goods that may be used in the research and development process and such items are expensed as consumed or expired. Provisions for slow moving, excess and obsolete inventories are provided based on product life cycle and development plans, product expiration and quality issues, historical experience and inventory levels.
Property and Equipment
Property and equipment are stated at cost, subject to review of impairment, and depreciated over the estimated useful lives of the assets (generally three to seven years) using the straight-line method. Amortization of leasehold improvements is computed over the shorter of the lease term or the estimated useful life of the related assets. Maintenance and repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in operating expense.
Goodwill, Intangible Assets and Other Long-Lived Assets
Goodwill represents the excess of cost over fair value of net assets acquired. Intangible assets include acquired technology, customer relationships, other license agreements and licensed technology (capitalized as part of the Affymetrix litigation). The cost of identified intangible assets is amortized on a straight-line basis over periods ranging from three to ten years unless the expected benefit pattern is declining, in which case an accelerated method is used.
The Company regularly performs reviews to determine if the carrying values of the long-lived assets are impaired. Goodwill and other intangible assets that have indefinite useful lives are reviewed for impairment at least annually during the second fiscal quarter, or more frequently if an event occurs indicating the potential for impairment. The Company performed its annual impairment test of goodwill in May of 2009, utilizing a test that begins with an estimate of the fair value of the reporting unit or intangible asset, noting no impairment and has determined there have been no impairment indicators for goodwill through January 3, 2010. A review of intangible assets that have finite useful lives and other long-lived assets is performed when an event occurs indicating the potential for impairment. If indicators of impairment exist, the Company assesses the recoverability of the affected long-lived assets by determining whether the carrying amount of such assets exceeds its estimated fair value. If impairment is indicated, the Company compares the carrying amount to the estimated fair value of the asset and adjusts the value of the asset accordingly. Factors that would necessitate an impairment assessment include a significant decline in the Company’s stock price and market capitalization compared to its net book value, significant changes in the ability of a particular asset to generate positive cash flows and significant changes in the Company’s strategic business objectives and utilization of the asset.
Reserve for Product Warranties
The Company generally provides a one-year warranty on genotyping, gene expression and sequencing systems. Additionally, the Company provides a warranty on its consumable sales through the expiry date, which generally ranges from six to twelve months after the manufacture date. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses based on historical experience as well as anticipated product performance. This expense is recorded as a component of cost of product revenue. Estimated warranty expenses associated with extended maintenance contracts for systems are recorded as a cost of service and other revenue ratably over the term of the maintenance contract. See Note 6 for further detailed discussion.

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Revenue Recognition
The Company’s revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of arrays, reagents, flow cells and instrumentation. Service and other revenue consists of revenue received for performing genotyping and sequencing services, extended warranty sales and amounts earned under research agreements with government grants, which are recognized in the period during which the related costs are incurred.
The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price to the buyer is fixed or determinable and collectibility is reasonably assured. In instances where final acceptance of the product or system is required, revenue is deferred until all the acceptance criteria have been met. All revenue is recorded net of any discounts.
Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided no significant obligations remain and collection of the receivable is reasonably assured. Revenue for genotyping and sequencing services is recognized when earned, which is generally at the time the genotyping or sequencing analysis data is made available to the customer or agreed upon milestones are reached.
In order to assess whether the price is fixed or determinable, the Company ensures there are no refund rights. If payment terms are based on future performance, the Company defers revenue recognition until the price becomes fixed or determinable. The Company assesses collectibility based on a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If the Company determines that collection of a payment is not reasonably assured, revenue recognition is deferred until the time collection becomes reasonably assured, which is generally upon receipt of payment.
Sales of instrumentation generally include a standard one-year warranty. The Company also sells separately priced maintenance (extended warranty) contracts, which are generally for one year, upon the expiration of the initial warranty. Revenue for extended warranty sales is recognized ratably over the term of the extended warranty period. Reserves are provided for estimated product warranty expenses at the time the associated revenue is recognized. If the Company were to experience an increase in warranty claims or if costs of servicing its products under warranty were greater than its estimates, gross margins could be adversely affected.
The Company regularly enters into contracts where revenue is derived from multiple deliverables including any mix of productsand/or services. These productsand/or services are generally delivered within a short time frame, approximately three to six months, of the contract execution date. Revenue recognition for contracts with multiple deliverables is based on the individual units of accounting determined to exist in the contract. A delivered item is considered a separate unit of accounting when the delivered item has value to the customer 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.
For transactions entered into during 2009, consideration is allocated at the inception of the contract to all deliverables based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (VSOE) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence exists, the Company uses its best estimate of the selling price for the deliverable. SeeRecent Accounting Pronouncementsin Note 1 for further information related to the Company’s change in authoritative accounting guidance for revenue recognition.
For transactions entered into prior to 2009, consideration was generally allocated to each unit of accounting based upon its relative fair value when objective and reliable evidence of fair value existed for all units of accounting in an arrangement. The fair value of an item was generally the price charged for the product, if the item was regularly sold on a stand-alone basis. In those instances when objective and reliable


F-11


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
evidence of fair value existed for the undelivered items but not for the delivered items, the residual method was used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equaled the total arrangement consideration less the aggregate fair value of the undelivered items. When the Company was unable to establish stand-alone value for delivered items or when fair value of undelivered items had not been established, revenue was deferred until all elements were delivered and services had been performed, or until fair value could objectively be determined for any remaining undelivered elements.
In order to establish VSOE of selling price, the Company must regularly sell the productand/or service on a standalone basis with a substantial majority priced within a relatively narrow range. VSOE of selling price is usually the midpoint of that range. If there is not a sufficient number of standalone sales and VSOE of selling price cannot be determined, then the Company considers whether third party evidence can be used to establish selling price. Due to the lack of similar products and services sold by other companies within the industry, the Company has rarely established selling price using third-party evidence. If neither VSOE nor third party evidence of selling price exists, the Company determines its best estimate of selling price using average selling prices over a rolling 12 month period as well as market conditions. If the product or service has no history of sales, the Company relies upon prices set by the Company’s pricing committee adjusted for applicable discounts.
The Company recognizes revenue for delivered elements only when it determines there are no uncertainties regarding customer acceptance. Changes in the allocation of the sales price between delivered and undelivered elements can impact the timing of revenue recognition but do not change the total revenue recognized on any arrangement.
Fair Value Measurements
The Company determines the fair value of its assets and liabilities based on 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 maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value:
• 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.
/s/  ROBERT S. EPSTEIN
DirectorFebruary 15, 2013

  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.

Shipping and Handling Expenses
Shipping and handling expenses are included in cost of product revenue and totaled $4.8 million, $3.7 million and $2.2 million for the years ended January 3, 2010, December 28, 2008 and December 30, 2007, respectively.
Research and Development
Research and development expenses consist of costs incurred for internal and grant-sponsored research and development. Research and development expenses include salaries, contractor fees, facilities costs, utilities and allocations of benefits. Expenditures relating to research and development are expensed in the period incurred.
Advertising Costs
The Company expenses advertising costs as incurred.  Advertising costs were $4.2 million, $3.4 million and $2.8 million for the years ended January 3, 2010, December 28, 2008 and December 30, 2007, respectively.
Leases
Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations, the Company records the total rent payable on a straight-line basis over the term of the lease, which includes the construction build-out period but excludes lease extension periods. The difference between rent payments and straight-line rent expense is recorded in other long-term liabilities. Landlord allowances are also recorded in other long-term liabilities, which are amortized on a straight-line basis over the lease term as a reduction to rent expense.
Income Taxes
The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date.
Deferred tax assets are regularly assessed to determine the likelihood they will be recovered from future taxable income. A valuation allowance is established when the Company believes it is more likely than not the future realization of all or some of a deferred tax asset will not be achieved. In evaluating the ability to recover deferred tax assets within the jurisdiction which they arise the Company considers all available positive and negative evidence. Factors reviewed include the cumulative pre-tax book income for the past three years, scheduled reversals of deferred tax liabilities, history of earnings and reliable forecasting, projections of pre-tax book income over the foreseeable future, and the impact of any feasible and prudent tax planning strategies.
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 thewith-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.


F-13


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The Company recognizes the impact of a tax position in the 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 in income tax expense.
Functional Currency
Prior to the third quarter of 2008, the Company identified the local currency as the functional currency in each of its foreign subsidiaries, with all translation adjustments recorded as part of other comprehensive income. Beginning in the third quarter of 2008, the Company reorganized its international structure to execute a more efficient relationship between product development, product manufacturing and sales. This reorganization increased the foreign subsidiaries’ dependence on the U.S. entity for management decisions, financial support, production assets and inventory, thereby making the foreign subsidiaries a direct and integral component of the U.S. entity’s operations. As a result, the Company reassessed the primary economic environment of its foreign subsidiaries, resulting in a U.S. dollar functional currency determination. Beginning in the third quarter of 2008, the Company remeasures its foreign subsidiaries’ assets and liabilities and revenue and expense accounts related to monetary assets and liabilities to the U.S. dollar and records the net gains or losses resulting from remeasurement in other income (expense), net in the consolidated statements of operations. Gains resulting from remeasurement were $0.4 million and $1.9 million for the years ended January 3, 2010 and December 28, 2008, respectively. There were no gains or losses resulting from remeasurement in the year ended December 30, 2007.
Derivatives
The Company is exposed to foreign exchange rate risks in the normal course of business. To manage a portion of the accounting exposure resulting from changes in foreign currency exchange rates, the Company enters into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of its subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in the value of the derivative are recognized in other income (expense), net, in the consolidated statements of operations for the current period, along with an offsetting gain or loss on the underlying assets or liabilities.
Stock-Based Compensation
The Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of stock options granted and stock purchases under the Employee Stock Purchase Plan (ESPP). This model incorporates various assumptions including expected volatility, expected option life, expected dividends, and the risk-free interest rates. The Company determines volatility by equally weighing the historical and implied volatility of the Company’s common stock. The historical volatility of the Company’s common stock over the most recent period is generally commensurate with the estimated expected life of the Company’s stock options, adjusted for the impact of unusual fluctuations not reasonably expected to recur and other relevant factors. The implied volatility is calculated from the implied market volatility of exchange-traded call options on the Company’s common stock. The expected life of an award is based on historical forfeiture experience, exercise activity, and on the terms and conditions of the stock awards granted to employees.

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Basic net income or loss per share is computed by dividing net income or loss by the weighted-average number of common shares outstanding during the reporting period. Diluted net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the reporting period increased to include dilutive potential common shares using the treasury stock method. Dilutive potential common shares consist of stock options with combined exercise prices and unrecognized compensation expense that are less than the average market price of the Company’s common stock, restricted stock units with unrecognized compensation expense, convertible debt when the average market price of the Company’s common stock is above the conversion price of $21.83 and warrants with exercise prices that are less than the average market price of the Company’s common stock. Under the treasury stock method, the amount that must be paid to exercise stock options and warrants, the amount of compensation expense for future services that the Company has not yet recognized for stock options and restricted stock units and the amount of tax benefits that will be recorded in additional paid-in capital when the awards become deductible are assumed to be used to repurchase shares. In loss periods, basic net loss per share and diluted net loss per share are identical since the effect of dilutive potential common shares is anti-dilutive and therefore excluded.

Recent Accounting Pronouncements
Adopted Accounting Pronouncements
Convertible Debt Instruments
In May 2008, the Financial Accounting Standards Board (FASB) issued authoritative guidance for convertible debt instruments that may be settled in cash upon conversion. The Company adopted the guidance effective December 29, 2008, impacting the accounting for the Company’s convertible senior notes by requiring the Company to account separately for the liability and equity components of the convertible debt. The liability component is measured at its estimated fair value such that the effective interest expense associated with the convertible debt reflects the issuer’s borrowing rate at the date of issuance for similar debt instruments without the conversion feature. The difference between the cash proceeds associated with the convertible debt and this estimated fair value is recorded as a debt discount and amortized to interest expense over the life of the convertible debt using the effective interest rate method. Upon application of this guidance, the only change to diluted earnings per share resulted from the effects of increased interest expense and the associated tax effects. The guidance requires retrospective application to the terms of instruments as they existed for all periods presented. See Note 7 for information on the impact of our adoption of the guidance and the assumptions we used to estimate the fair value of the liability component.
Derivatives
In June 2008, the FASB ratified authoritative guidance addressing the accounting for certain instruments (or embedded features) determined to be indexed to an entity’s own stock. This guidance provides that an entity should use a two-step approach to evaluate whether an equity-linked financial instrument (or embedded feature) is indexed to its own stock, including evaluating the instrument’s contingent exercise and settlement provisions. The Company adopted this guidance effective December 29, 2008, requiring the Company to perform additional analyses on both its freestanding equity derivatives and embedded equity derivative features. However, the adoption of this guidance did not have a material effect on the Company’s consolidated financial statements.
Fair Value of Financial Instruments
In April 2009, the FASB issued additional authoritative guidance on the fair value of financial instruments, which provides:
  further provisions on estimating fair value when the markets become inactive and quoted prices reflect distressed transactions;
 
/s/  PAUL GRINT

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The Company adopted the guidance on a prospective basis in the interim period ended June 28, 2009 without material impact on the Company’s consolidated financial statements. Refer to Note 3 for further detailed discussion on the fair value of financial instruments.
Accounting for Subsequent Events
In May 2009, the FASB issued authoritative guidance related to general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The Company adopted this guidance in the interim period ended June 28, 2009 without material impact on the Company’s consolidated financial statements.
FASB Codification
In June 2009, the FASB issued authoritative guidance for the FASB Codification to become the source of authoritative, nongovernmental GAAP. The Codification did not change GAAP but reorganizes the literature. The Company adopted this guidance in the interim period ended September 27, 2009 without material impact on the Company’s consolidated financial statements.
Revenue Recognition
In September 2009, the FASB ratified authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables. The guidance affects the determination of separate units of accounting in arrangements with multiple deliverables and the allocation of transaction consideration to each of the identified units of accounting. Previously, a delivered item was considered a separate unit of accounting when it had value to the customer on a stand-alone basis and there was objective and reliable evidence of the fair value of the undelivered items. The new guidance eliminates the requirement for objective and reliable evidence of fair value to exist for the undelivered items in order for a delivered item to be treated as a separate unit of accounting. The guidance also requires arrangement consideration to be allocated at the inception of the arrangement to all deliverables using the relative-selling-price method and eliminates the use of the residual method of allocation. Under the relative-selling-price method, the selling price for each deliverable is determined using VSOE of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists for a deliverable, the guidance requires an entity to determine the best estimate of the selling price.
The Company adopted the guidance on a prospective basis in the interim period ended September 27, 2009. Prospective application required the Company to apply the guidance to all revenue arrangements entered into or materially modified since the beginning of fiscal 2009. This prospective application had no impact on the Company’s consolidated financial statements for the interim periods ended March 29, 2009 and June 28, 2009. During the third and fourth quarter of 2009, the Company recorded additional revenue of $2.3 million and $5.7 million respectively, which would have been deferred under previous accounting guidance. In future interim and fiscal year periods, the adoption of this guidance may have a material impact on the Company’s financial results to the extent the Company enters into arrangements with multiple deliverables and does not have VSOE or third party evidence of selling price for material undelivered elements. Refer to theSummary of Significant Accounting Principlesin Note 1 for further information on the Company’s revenue recognition policies.
In September 2009, the FASB also ratified authoritative accounting guidance requiring the sales of all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality to be excluded from the scope of the software revenue guidance. The Company adopted the guidance on a prospective basis during the three months ended September 27, 2009 effective for all periods in 2009. Prior to the adoption of this guidance, the Company assessed all software items included in the Company’s product offerings to be incidental to the product itself and, therefore,


F-18


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
excluded all sales from the scope of the related software revenue guidance. As a result, the adoption of this guidance had no impact on the Company’s consolidated financial statements.
Definition of a Business
During 2009, the FASB revised guidance related to business combinations, which changed the definition of a business. Previously, a business was defined as having three elements: (i) inputs, (ii) processes applied to those inputs, and (iii) outputs. The new guidance broadens the definition and no longer requires the third element to be present for a set of activities and assets to be considered a business. The Company has adopted this guidance for the interim period ending January 3, 2010. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
Fair Value of Liabilities
In August 2009, the FASB issued authoritative guidance related to measuring liabilities at fair value when a quoted price in an active market is not available. This guidance is effective for reporting periods beginning after August 28, 2009. The Company has adopted this guidance in the interim period ending January 3, 2010. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
New Accounting Pronouncements
Variable Interest Entities
In June 2009, the FASB issued authoritative guidance that amends the evaluation criteria to identify the primary beneficiary of a variable interest entity and requires a quarterly reassessment of the treatment of such entities. The guidance also requires additional disclosures about an enterprise’s involvement in a variable interest entity. The Company will adopt this guidance in the first interim period of fiscal 2010 and is currently evaluating the impact of the pending adoption on the consolidated financial statements.

Trading Securities
At January 3, 2010, the Company’s trading securities consisted of $54.9 million (at cost) in auction rate securities issued primarily by municipalities and universities. The auction rate securities are held in a brokerage account with UBS Financial Services, Inc., a subsidiary of UBS. These securities are debt instruments with a long-term maturity and with an interest rate that is reset in short intervals through auctions.
The markets for auction rate securities effectively ceased when the vast majority of auctions failed in February 2008, preventing investors from selling these securities. As of January 3, 2010, the securities continued to fail auction and remained illiquid. Changes in the fair value of the Company’s auction rate securities from December 28, 2008 through January 3, 2010 are as follows (in thousands):
     
Fair value as of December 28, 2008 $47,235 
Redeemed by issuer  (1,000)
Unrealized Gain(1)  2,536 
     
Fair value as of January 3, 2010 $48,771 
     
(1)Unrealized gains and losses associated with the Company’s auction rate securities are classified as other income (expense), net in the consolidated statements of operations for the year ended January 3, 2010.
In determining the fair value of the Company’s auction rate securities, the Company considered trades in the secondary market. However, due to the auction failures of the auction rate securities in the marketplace and the lack of trading in the secondary market of these instruments, there was insufficient observable auction rate security market information available to directly determine the fair value of the Company’s investments. As a result, the value of these securities and resulting unrealized gain was determined using Level 3 hierarchical inputs. These inputs include management’s assumptions of pricing by market participants, including assumptions about risk. The Company used the concepts of fair value based on estimated discounted future cash flows of interest income over a projected 17 year period, which is reflective of the weighted average life of the student loans in the underlying trust. In preparing this model, the Company used historical data of the rates upon which a majority of the auction rate securities’ contractual rates were based, such as the LIBOR and average trailing twelve-month90-day treasury interest rate spreads, to estimate future interest rates. The Company also considered the discount factors, taking into account the credit ratings of the auction rate securities, using a range of discount rates from 5.9% to 7.2%. The Company obtained information from multiple sources, including UBS, to determine a reasonable range of assumptions to use in valuing the auction rate securities. The Company’s model was corroborated by a separate comparable cash flow analysis prepared by UBS. To understand the sensitivity of the Company’s valuation, the liquidity factor and estimated

remaining life was varied. Variations in those results were evaluated and it was determined the factors and valuation method chosen were reasonable and representative of the Company’s auction rate security portfolio.
As a result of the auction rate failures, various regulatory agencies initiated investigations into the sales and marketing practices of several banks and broker-dealers, including UBS, which sold auction rate securities, alleging violations of federal and state laws. Along with several other broker-dealers, UBS subsequently reached a settlement with the federal and state regulators that required them to repurchase auction rate securities from certain investors at par at some future date. In November 2008, the Company signed a settlement agreement granting the Company an option to sell its auction rate securities at par value to UBS during the period of June 30, 2010 through July 2, 2012 (the Settlement). In accepting the Settlement, the Company released UBS from any claims relating to the marketing and sale of auction rate securities. Although the Company expects to sell its auction rate securities under the Settlement, if the Settlement is not exercised before July 2, 2012, it will expire and UBS will have no further rights or obligation to buy the Company’s auction rate securities. In lieu of the acceptance of the Settlement, the auction rate securities will continue to accrue interest as determined by the auction process or the terms outlined in the prospectus of the auction rate securities if the auction process fails. In addition to offering to repurchase the Company’s auction rate securities, as part of the Settlement, UBS has agreed to provide the Company with a “no net cost” loan up to 75% of the par value of the auction rate securities until June 30, 2010. According to the terms of the Settlement, the interest rate on the loan will approximate the weighted average interest or dividend rate payable to the Company by the issuer of any auction rate securities pledged as collateral.
UBS’s obligations under the Settlement are not secured by its assets and do not require UBS to obtain any financing to support its performance obligations under the Settlement. UBS has disclaimed any assurance that it will have sufficient financial resources to satisfy its obligations under the Settlement.
To account for the Settlement, the Company recorded a separate freestanding asset (put option) of $8.7 million and recognized a corresponding gain in earnings during the fourth quarter of 2008. Changes in the fair value of the Company’s put option from December 28, 2008 through January 3, 2010 are as follows (in thousands):
     
Fair value as of December 28, 2008 $8,665 
Unrealized loss(1)  (2,536)
     
Fair value as of January 3, 2010 $6,129 
     
(1)Unrealized gains and losses associated with the Company’s put option are classified as other income (expense), net in the consolidated statements of operations for the year ended January 3, 2010.
Since the put option does not meet the definition of a derivative instrument, the Company elected to measure it at fair value in accordance with authoritative guidance related to the fair value option for financial assets and financial liabilities. The Company valued the put option using a discounted cash flow approach including estimates of interest rates, timing and amount of cash flow, with consideration given to UBS’s financial ability to repurchase the auction rate securities beginning June 30, 2010. These assumptions are volatile and subject to change as the underlying sources of these assumptions and market conditions change.
The Company will continue to recognize gains and losses in earnings approximating the changes in the fair value of the auction rate securities at each balance sheet date. These gains and losses are expected to be approximately offset by changes in the fair value of the put option.
The fair value of the auction rate securities and the put option total $54.9 million and $55.9 million at January 3, 2010 and December 28, 2008, respectively. At January 3, 2010, the auction rate securities were classified as short-term investments as the Company intends to exercise the right to sell the securities back to UBS within the next year. At December 28, 2008, the Company classified these securities as long-term assets

since the Company believed it would not able to liquidate its investments without significant loss during the year ended January 3, 2010.
4.  Intangible Assets
The Company’s intangible assets are comprised primarily of licensed technology from the Affymetrix settlement entered into on January 9, 2008 and acquired core technology and customer relationships from the acquisition of Solexa. As a result of the Affymetrix settlement, the Company agreed, without admitting liability, to make a one-time payment to Affymetrix of $90.0 million. In return, Affymetrix agreed to dismiss with prejudice all lawsuits it had brought against the Company, and the Company agreed to dismiss with prejudice its counterclaims in the relevant lawsuits. Affymetrix also agreed not to sue the Company or its affiliates or customers for making, using or selling any of the Company’s current products, evolutions of those products or services related to those products. In addition, Affymetrix agreed that, for four years, it will not sue the Company for making, using or selling the Company’s products or services that are based on future technology developments. The covenant not to sue covers all fields other than photolithography, the process by which Affymetrix manufactures its arrays and a field in which the Company does not operate.
Of the total $90.0 million payment made on January 25, 2008, $36.0 million was recorded as licensed technology and classified as an intangible asset. The remaining $54.0 million was charged to expense during the fourth quarter of 2007. This allocation was determined based on the fair value of past and estimated future revenue streams related to the products covered by the patents previously under dispute. The value of the licensed technology is the benefit derived, calculated using estimated discounted cash flows and future revenue projections, from the perpetual covenant not to sue for damages related to the sale of the Company’s current products. The effective life of the licensed technology extends through 2015, the final expiry date of all patents considered in valuing the intangible asset. The related amortization is based on the higher of the percentage of usage or the straight-line method. The percentage of usage was determined using actual and projected revenues generated from products covered by the patents previously under dispute.
Acquired core technology and customer relationships are being amortized on a straight-line basis over their effective useful lives of ten and three years, respectively. The amortization of the Company’s intangible assets is excluded from cost of product revenue and is separately classified as amortization of intangible assets on the Company’s consolidated statements of operations.
The following is a summary of the Company’s amortizable intangible assets as of the respective balance sheet dates (in thousands):

5.  Impairment of Manufacturing Equipment
During fiscal 2008, the Company implemented next-generation imaging and decoding systems to be used in manufacturing. These systems were developed to increase existing capacity and allow the Company to transition to the Infinium High-Density (HD) product line. As a result of this transition, the demand for products manufactured on the previous infrastructure was reduced and certain systems were no longer being utilized. A non-cash impairment charge of $4.1 million was recorded in the second quarter of fiscal 2008 for the excess machinery. This charge is included as a separate line item in the Company’s consolidated statement of operations. There was no change to useful lives and related depreciation expense of the remaining assets as the Company believes these estimates are currently reflective of the period the assets will be used in operations.
6.  Warranties
The Company generally provides a one-year warranty on genotyping, gene expression and sequencing systems. Additionally, the Company provides a warranty on its consumable sales through the expiry date, which generally ranges from six to twelve months after the manufacture date. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses based on historical experience as well as anticipated product performance. This expense is recorded as a component of cost of product revenue. Estimated warranty expenses associated with extended maintenance contracts for systems are recorded as a cost of service and other revenue ratably over the term of the maintenance contract.

7.  Convertible Senior Notes
On February 16, 2007, the Company issued $400.0 million principal amount of 0.625% convertible senior notes due 2014. The net proceeds from the offering, after deducting the initial purchasers’ discount and offering expenses, were approximately $390.3 million. The Company will pay 0.625% interest per annum on the principal amount of the notes, payable semi-annually in arrears in cash on February 15 and August 15 of each year. The Company made interest payments of $1.2 million on February 15, 2009 and August 15, 2009. The notes mature on February 15, 2014.
The notes will be convertible into cash and, if applicable, shares of the Company’s common stock, $0.01 par value per share, based on a conversion rate, subject to adjustment, of 45.8058 shares per $1,000 principal amount of notes (which represents a conversion price of approximately $21.83 per share), only in the following circumstances and to the following extent: (1) during the fivebusiness-day period after any five consecutivetrading-day period (the measurement period) in which the trading price per note for each day of such measurement period was less than 97% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; (2) during any calendar quarter, if the last reported sale price of the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; (3) upon the occurrence of specified events; and (4) at any time on or after November 15, 2013 through the third scheduled trading day immediately preceding the maturity date. The requirements of the second condition above were satisfied during the first, second and third quarters of 2009. Accordingly, the notes were convertible during the period from, and including, April 1, 2009 through, and including, December 31, 2009. Additionally, these same requirements were satisfied during the third quarter of 2008, and, as a result, the notes were convertible during the period from, and including, October 1, 2008 through, and including, December 31, 2008. On December 29, 2008, a noteholder converted notes in an aggregate principal amount of $10.0 million. On February 4, 2009, the settlement date, we paid the noteholder the conversion value of the notes in cash, up to the principal amount of the notes. The excess of the conversion value over the principal amount, totaling $2.9 million, was paid in shares of common stock. This equity dilution upon conversion of the notes was offset by the reacquisition of the shares under the convertible note hedge transactions entered into in connection with the offering of the notes.
The hedge transaction entered with the initial purchasersand/or their affiliates (the hedge counterparties) entitles the Company to purchase up to 18,322,320 shares of the Company’s common stock at a strike price of approximately $21.83 per share, subject to adjustment. In addition, the Company sold to these hedge counterparties warrants exercisable, on a cashless basis, for up to 18,322,320 shares of the Company’s common stock at a strike price of $31.435 per share, subject to adjustment. The cost of the hedge transaction that was not covered by the proceeds from the sale of the warrants was approximately $46.6 million and was reflected as a reduction of additional paid-in capital. The hedge transaction is expected to reduce the potential equity dilution upon conversion of the notes to the extent the Company exercises the hedge to purchase shares from the hedge counterparties to deliver to converting noteholders. However, the warrants could have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock exceeds the strike price of the warrants.

The new guidance requires the carrying amount of the liability component to be estimated by measuring the fair value of a similar liability that does not have an associated conversion feature. As the Company was unable to find any other comparable companies in industry and size with outstanding non-convertible public debt, the Company determined that senior, unsecured corporate bonds represent a similar liability to the convertible senior notes without the conversion option. To measure the fair value of the similar liability at February 16, 2007, the Company estimated an interest rate using assumptions that market participants would use in pricing the liability component, including market interest rates, credit standing, yield curves and volatilities, all of which are defined as Level 2 Observable Inputs. The estimated interest rate of 8.27% was applied to the convertible senior notes and coupon interest using a present value technique to arrive at the fair value of the liability component. The difference between the cash proceeds associated with the convertible debt and this estimated fair value of the liability component is recorded as an equity component. We classified a portion of the equity component as temporary equity measured as the excess of a) the amount of cash that would be required to be paid upon conversion over b) the current carrying amount of the liability-classified component. This amount is reflected within conversion option subject to cash settlement in the consolidated balance sheets.
As of December 28, 2008, the principal amount of the convertible senior notes was $400.0 million and the unamortized discount was $123.1 million resulting in a net carrying amount of the liability component of $276.9 million. As of January 3, 2010, the principal amount of the liability component was $390.0 million due to the conversion of $10.0 million of the notes during the first quarter of 2009. Upon conversion, the Company recorded a gain of $0.8 million in the first quarter of 2009, calculated as the difference between the carrying amount of the converted notes and their estimated fair value as of the settlement date. To measure the fair value of the converted notes as of the settlement date, the Company calculated an interest rate of 11.3% using Level 2 Observable Inputs. This rate was applied to the converted notes and coupon interest rate using the same present value technique used in the issuance date valuation. The unamortized discount on the remaining convertible senior notes as of January 3, 2010 was $99.8 million, resulting in a net carrying amount of $290.2 million. The remaining period over which the discount on the liability component will be amortized is 4.12 years.

Employee Stock Purchase Plan
In February 2000, the board of directors and stockholders adopted the 2000 ESPP. A total of 15,467,426 shares of the Company’s common stock have been reserved for issuance under the ESPP. The ESPP permits eligible employees to purchase common stock at a discount, but only through payroll deductions, during defined offering periods.
The price at which stock is purchased under the ESPP is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. The initial offering period commenced in July 2000. In addition, beginning with fiscal 2001, the ESPP provides for annual increases of shares available for issuance by the lesser of 3% of the number of outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, 3,000,000 shares or such lesser amount as determined by the Company’s board of directors. Shares totaling 359,713, 276,198 and 266,962 were issued under the ESPP during fiscal 2009, 2008 and 2007, respectively. As of January 3, 2010, there were 13,434,449 shares available for issuance under the ESPP.
Restricted Stock Units
In 2007 the Company began granting restricted stock units pursuant to its 2005 Stock and Incentive Plan as part of its periodic employee equity compensation review program. Restricted stock units are share awards that, upon vesting, will deliver to the holder shares of the Company’s common stock. Restricted stock units granted during 2007 vest over four years as follows: 15% vest on the first and second anniversaries of the grant date, 30% vest on the third anniversary of the grant date and 40% vest on the fourth anniversary of the grant date. Effective January 2008, the Company changed the vesting schedule for grants of new restricted stock units. Currently, restricted stock units vest 15% on the first anniversary of the grant date, 20% on the second anniversary of the grant date, 30% on the third anniversary of the grant date and 35% on the fourth anniversary of the grant date. The Company satisfies restricted stock units vesting through the issuance of new shares.
A summary of the Company’s restricted stock unit activity and related information from January 1, 2007 through January 3, 2010 is as follows:

Based on the closing price per share of the Company’s common stock of $30.68 on December 31, 2009, the total pretax intrinsic value of all outstanding restricted stock units on that date was $81.1 million.
Warrants
In conjunction with its acquisition of Solexa, Inc. on January 26, 2007, the Company assumed 4,489,686 warrants issued by Solexa prior to the acquisition. During the year ended January 3, 2010, there were 954,376 warrants exercised, resulting in cash proceeds to the Company of approximately $7.6 million.

Treasury Stock
In October 2008, the board of directors authorized a $120.0 million stock repurchase program. In fiscal 2008, the Company repurchased 3.1 million shares for $70.8 million under the program.
In July 2009, the board of directors authorized a $75.0 million stock repurchase program and concurrently terminated the $120.0 million stock repurchase program authorized in October 2008. In November 2009, upon the completion of the repurchase program authorized in July 2009, our board of directors authorized an additional $100.0 million stock repurchase program. In fiscal 2009, the Company repurchased a total of 6.1 million shares for $175.1 million under both programs in open-market transactions or through privately negotiated transactions in compliance withRule 10b-18 under the Securities Exchange Act of 1934.
Stockholder Rights Plan
On May 3, 2001, the board of directors of the Company declared a dividend of one preferred share purchase right (a Right) for each outstanding share of common stock of the Company. The dividend was payable on May 14, 2001 (the Record Date) to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one unit consisting of one-thousandth of a share of its Series A Junior Participating Preferred Stock at a price of $100 per unit. The Rights will be exercisable if a person or group hereafter acquires beneficial ownership of 15% or more of the outstanding common stock of the Company or announces an offer for 15% or more of the outstanding common stock. If a person or group acquires 15% or more of the outstanding common stock of the Company, each Right will entitle its holder to purchase, at the exercise price of the Right, a number of shares of common stock having a market value of


F-32


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
two times the exercise price of the Right. If the Company is acquired in a merger or other business combination transaction after a person acquires 15% or more of the Company’s common stock, each Right will entitle its holder to purchase, at the Right’s then-current exercise price, a number of common shares of the acquiring company which at the time of such transaction have a market value of two times the exercise price of the Right. The board of directors will be entitled to redeem the Rights at a price of $0.01 per Right at any time before any such person acquires beneficial ownership of 15% or more of the outstanding common stock. The Rights expire on May 14, 2011 unless such date is extended or the Rights are earlier redeemed or exchanged by the Company.
10.  Legal Proceedings
From time to time, we are party to litigation and other legal proceedings in the ordinary course, and incidental to the conduct, of our business. While the results of any litigation or other legal proceedings are uncertain, management does not believe the ultimate resolution of any pending legal matters is likely to have a material adverse effect on our financial position or results of operations.

A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on ajurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. Based on the available evidence as of January 3, 2010, the Company was not able to conclude it is more likely than not certain U.S. and foreign deferred tax assets will be realized. Therefore, the Company


F-34


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
recorded a valuation allowance of $2.8 million and $12.1 million against certain U.S. and foreign net deferred tax assets, respectively.
As of January 3, 2010, the Company had net operating loss carryforwards for federal and state tax purposes of $25.4 million and $132.1 million, respectively, which begin to expire in 2012 and 2013, respectively, unless previously utilized. In addition, the Company also had U.S. federal and state research and development tax credit carryforwards of $16.0 million and $16.2 million, respectively, which begin to expire in 2018 and 2019, respectively, unless previously utilized.
As of January 3, 2010, the valuation allowance includes $12.3 million of pre-acquisition foreign deferred tax assets of Solexa. In accordance with the adoption of Topic 805 to the extent any of these assets are recognized in the future the adjustment will be recorded as a reduction to the provision for income taxes.
Pursuant to Section 382 and 383 of the Internal Revenue Code, utilization of the Company’s net operating loss and credits may be subject to annual limitations in the event of any significant future changes in its ownership structure. These annual limitations may result in the expiration of net operating losses and credits prior to utilization. The deferred tax assets as of January 3, 2010 are net of any previous limitations due to Section 382 and 383.
Due to the adoption of SFAS No. 123R, 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 thewith-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. During 2009, the Company realized $39.3 million of such excess tax benefits, and accordingly recorded a corresponding credit to additional paid in capital. As of January 3, 2010, the Company has $17.1 million of unrealized excess tax benefits associated with share-based compensation. These tax benefits will be accounted for as a credit to additional paid-in capital, if and when realized, rather than a reduction of the provision for income taxes.
The Company’s manufacturing operations in Singapore operate under various tax holidays and incentives that begin to expire in 2018. For the year ended January 3, 2010, these tax holidays and incentives resulted in an approximate $2.3 million decrease to the provision for income taxes and an increase to net income per diluted share of $0.02.
Residual U.S. income taxes have not been provided on $38.6 million of undistributed earnings of foreign subsidiaries as of January 3, 2010, since the earnings are considered to be indefinitely invested in the operations of such subsidiaries.
The following table summarizes the gross amount of the Company’s uncertain tax positions (in thousands):

Balance at end of year $11,760  $9,402  $7,000 
             
During 2009 the Company determined that $14.4 million of previously reported uncertain tax positions, which related to pre-acquistion net operating loss carryforwards of Solexa, were not uncertain as of the Solexa acquisition in January 2007. Accordingly, the uncertain tax position balances that were previously reported have been reduced by $14.4 million to correctly present the uncertain tax position balances.


F-35


ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
As of January 3, 2010, $9.6 million of the Company’s uncertain tax positions would reduce the Company’s annual effective tax rate, if recognized.
The Company does not expect its uncertain tax positions to change significantly over the next 12 months. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense. As of January 3, 2010, no interest or penalties have been accrued related to the Company’s uncertain tax positions. Tax years 1995 to 2009 remain subject to future examination by the major tax jurisdictions in which the Company is subject to tax.
12.  Employee Benefit Plans
Retirement Plan
The Company has a 401(k) savings plan covering substantially all of its employees. Company contributions to the plan are discretionary. During the years ended January 3, 2010, December 28, 2008 and December 30, 2007, the Company made matching contributions of $3.3 million, $2.6 million and $1.4 million, respectively.
Executive Deferred Compensation Plan
For the Company’s executives and members of the board of directors, the Company adopted the Illumina, Inc. Deferred Compensation Plan (the Plan) that became effective January 1, 2008. Eligible participants can contribute up to 80% of their base salary and 100% of all other forms of compensation into the Plan, including bonus, commission and director fees. The Company has agreed to credit the participants’ contributions with earnings that reflect the performance of certain independent investment funds. On a discretionary basis, the Company may also make employer contributions to participant accounts in any amount determined by the Company. The vesting schedules of employer contributions are at the sole discretion of the Compensation Committee. However, all employer contributions shall become 100% vested upon the occurrence of the participant’s disability, death or retirement or a change in control of the Company. The benefits under this plan are unsecured. Participants are generally eligible to receive payment of their vested benefit at the end of their elected deferral period or after termination of their employment with the Company for any reason or at a later date to comply with the restrictions of Section 409A. As of January 3, 2010, no employer contributions were made to the Plan.
In January 2008, the Company also established a rabbi trust for the benefit of its directors and executives under the Plan. In accordance with authoritative guidance related to consolidation of variable interest entities and accounting for deferred compensation arrangements where amounts earned are held in a rabbi trust and invested, the Company has included the assets of the rabbi trust in its consolidated balance sheet since the trust’s inception. As of January 3, 2010, the assets of the trust and liabilities of the Company were $4.0 million. The assets and liabilities are classified as other assets and accrued liabilities, respectively, on the Company’s balance sheet as of January 3, 2010. Changes in the values of the assets held by the rabbi trust accrue to the Company.
13.  Segment Information, Geographic Data and Significant Customers
During the first quarter of 2008, the Company reorganized its operating structure into a newly created Life Sciences Business Unit, which includes all products and services related to the research market, namely the sequencing, BeadArray, and VeraCode product lines. The Company also created a Diagnostics Business Unit to focus on the emerging opportunity in molecular diagnostics. For the year ended January 3, 2010, the Company had limited activity related to the Diagnostics Business Unit, and operating results were reported on an aggregate basis to the chief operating decision maker of the Company, the chief executive officer.
