PART I
ITEM 1.Business
 
Overview
 
We are a leading developer, manufacturer, and marketer of integrated systems for the large scale 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, San Diego, California 92121. Our telephone number is(858) 202-4500.
Using our proprietary technologies, we provide a comprehensive line of products and services that currently serve the sequencing, genotyping, and gene expression markets. In the future,markets, and we expect to enter the market for molecular diagnostics. Our customers include leading genomic research centers, pharmaceutical companies, academic institutions, clinical research organizations, and biotechnology companies.
We develop and commercialize sequencing technologies used to perform a range of analyses, including de novo sequencing, whole genome re-sequencing, gene expression analysis, and small RNA analysis. Our product and service offerings also include leading-edge solutions for single-nucleotide polymorphism (SNP) genotyping, copy number variation (CNV), DNA methylation studies, gene expression profiling, and low-multiplex analysis of DNA, RNA, and protein. We believe we are the only company with genome-scale technology for sequencing, genotyping, and gene expression — the three cornerstones of modern genetic analysis.
Our tools provide researchers around the world with the performance, throughput, cost effectiveness, and flexibility necessary to performdetermine and analyze the billions of bits of genetic testsinformation 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 April 2005, we completed the acquisition of CyVera Corporation (Cyvera). The aggregate consideration for the transaction was $17.5 million, consisting of approximately 1.5 million shares of our common stock and payment of approximately $2.3 million of CyVera’s liabilities at the closing.

On January 26, 2007 we completed the acquisition ofacquired Solexa, Inc. (Solexa) for approximately 13.1 million sharesAs a result of that transaction, we acquired the sequencing technology utilized in our common stock. Solexa developsHiSeq 2000 and commercializes genetic analysis technologies used toGenome Analyzer instrument platforms. These products perform DNA sequencing based on a range of analyses, including whole genome resequencing, gene expression analysis and small RNA analysis. We believe our combined company is the only company with genome-scale technology for genotyping, gene expression and sequencing, the three cornerstones of modern genetic analysis.proprietary reversible terminatorsequencing-by-synthesis (SBS) chemistry.
 
We were incorporated in California in April 1998. We reincorporated in Delaware in July 2000. Our principal executive officesDuring 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 locatedreported on an aggregate basis as one operating segment. In the future, at 9885 Towne Centre Drive, San Diego, California 92121. Our telephone number is(858) 202-4500.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 Protein
The genetic content that controls an organism’s living cells is encoded in deoxyribonucleic acid, or DNA. The human body, for instance, is composed of billions of cells, each containing DNA, which encodes the basic instructions for cellular function. The complete set of an organism’s DNA is called its genome. The human genome is organized into 23 pairs of chromosomes that are further divided into over 30,000 smaller regions called genes. Each gene is comprised of a string of nucleotide bases labeled A, C, G, and T, representing adenine, cytosine, guanine, and thymine, respectively. Human DNA has approximately 3 billion nucleotide bases and their 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 — is used as a template to direct the synthesis of a protein. Proteins, in turn, direct all cellular function.

Genetic 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 differences are referred to as genetic variation. Examples of the physical consequences of genetic variation include differences in eye and hair color. Genetic variation 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 to the same drug treatment. Some people may respond well, others may not respond at all, and still others may experience adverse side effects. A common form of genetic variation is a single-nucleotide polymorphism, or SNP. A SNP is a variation in a single position of a nucleotide base in a DNA sequence. It is estimated that the human genome contains over nine30 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 majorcommon diseases. Since there are millions of SNPs, it is important to investigate many representative, well-chosen SNPs simultaneously in order to discover medically valuable information.
 
Another contributor to disease and dysfunction 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 patterns and their relationship to disease. Until recently,Historically, this problem was addressed by investigating effects on agene-by-gene basis. This is time consuming, 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.
 
There are multiple methods of studying genetic variation and biological function, including sequencing, SNP genotyping, and gene expression profiling, each of which is uniquely addressed in our breadth of products and services. Our broad portfolio of current products and services supports a range 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 variation at the DNA, RNA, and protein levels.
Sequencing
DNA sequencing is 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 understanding 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 changes 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. 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 the development of new array products for broader testing and biomarker validation.
In tag sequencing, short sequences, often representative of a larger molecule 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, 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 individualassociation 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 other organism.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 and to apply that information to clinical trials and diagnostic testing, requires the analysis of millions of SNP genotypes and the testing of large populations for each disease. For example, a single large clinical trialstudy could involve genotyping more than 1,000,000 SNPs per patientsample in more than 1,000 patients,samples, thus requiring 1one 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-basedgenomics 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 commercial 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 (DNA) 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 genes or groups of genes that play a role in these processes can be identified. Studies of this type, often used in drug discovery, require monitoring thousands, 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.
 
SequencingMolecular Diagnostics
 
DNA sequencingMolecular diagnostics is the process of determiningexamining 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 orderefficacy or safety of bases (A, C, Gdrug 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 tools as well as in genetic disease susceptibility testing. Molecular diagnostic tests can also be used to identify a disease, monitor its progression and response to treatment, or T)predict individual predisposition to a disease and individual response to treatment. By identifying small, individual genetic differences — or variants — that lie at the root of differing drug responses, molecular diagnostic tests can be used to select appropriate medication and dosage.
Our Principal Markets
From our inception, we have believed that the analysis of genetic variation and function will play an increasingly important role in molecular biology and that by empowering genetic analysis, our tools will further disease research, drug development, and the development of molecular tests. Our customers include leading genomic research centers, academic institutions, clinical research organizations, and pharmaceutical

and biotechnology companies. In addition, fundamental developments in recent years have created significant new opportunities for us in the emerging market of molecular diagnostics.
Life Sciences Research Market
The life sciences research market consists of laboratories generally associated with universities, medical research centers, government institutions such as the United States National Institutes of Health, and other research institutions as well as biotechnology and pharmaceutical companies. Researchers at these institutions are using our products and services in a DNA sample,broad spectrum of scientific activities, such as: next-generation sequencing,mid-to-high-complexity genotyping and gene expression (for whole-genome discovery and profiling), and low complexity genotyping and gene expression (for high-throughput targeted screening). Next-generation sequencing is the most rapidly growing of these three areas. It is fueled by private and public funding, new global initiatives to broadly characterize genetic variation, and the migration of legacy genetic applications to sequencing based technologies.
Applied Markets
We provide products and services to enable or improve activities in particular markets, which can be further divided into de novo sequencing, re-sequencing,we refer to as applied markets. A current focus of our products for these markets is in the area of agricultural research, including microarrays that contain SNPs for custom and tagfocused genotyping of seeds and crops (such as maize) and livestock (such as cattle, horses, pigs, and sheep). The applied markets may also include opportunities for our products and services in the fields of forensic analysis, veterinary diagnostics, cytogenics, retail pet genomics, and consumer genotyping and sequencing. In de novoJuly 2009, we launched a service program to provide high-quality personal genome sequencing the goal isfor consumers. In connection with our personal sequencing service, we collaborate with a number of partners, including 23andMe, Inc.; deCODE genetics ehf; Knome, Inc.; National Center for Genome Resources; Navigenics, Inc.; and Pathway Genomics, to determine the sequenceencourage secondary data analysis of a representative sample frompersonal genome, such as calculation of disease risk, ancestry, and information on traits of interest. Although we do not perform personal genotyping directly as a species never before sequenced. Understandingservice, several companies use our technology and products to provide personal genotyping services.
Molecular Diagnostics Market
The primary growth drivers in the similaritiesmolecular diagnostics market are the continued discovery of genetic markers with proven clinical utility, the increasing adoption of genetic based diagnostic tests, and differencesthe expansion of reimbursement programs to include a greater number of approved diagnostic tests. We believe that molecular diagnostic tests will create a fundamental shift in DNA sequence between many species can help to improve our understandingboth the practice of medicine and the economics of the functionpharmaceutical industry by creating an increased emphasis on preventative and predictive molecular medicine. Physicians will be able to use these tests for the early detection of disease and to treat patients on a personalized basis, allowing them to select the most effective therapy with the fewest side effects. We believe our BeadXpress instrument platform, using our VeraCode technology, is ideally suited to provide a cost-effective, high-throughput, mid- to low-multiplex solution to the molecular diagnostic market. During the third quarter of 2009, we submitted our BeadXpress instrument platform for review by the U.S. Food and Drug Administration (FDA). Assuming FDA approval of this instrument platform, we plan to develop clinical diagnostic testing panels for use on the BeadXpress instrument platform, including possible panels for multi-drug resistant organisms, herpes, and respiratory viruses, and we expect to continue research into 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 cytogenetics test intended to be used as an aid in the postnatal diagnosis of chromosomal abnormalities known to be associated with developmental delay and mental retardation. The pre-IDE package included our iScan instrument platform together with associated microarrays, reagents, and software. Following completion of the structures found inIDE process, we intend to seek FDA clearance for the DNA.
In re-sequencing, the sequence of samples from a given species is determined generally comparing each to a standard or reference sequence. This is an extremely comprehensive form of genotyping, in which every single base is characterized for possible mutations. In tag sequencing, short sequences, each representative of a larger molecule or genomic location, are detectediScan instrument platform 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 tag sequence may exist for each gene, and the number of copies of this tag which are detected in an experiment is a measure of how actively that gene is being expressed in the tissue sample being analyzed.related reagents.

Our Principal Technologies
 
Sequencing Technology
Our DNA sequencing technology is based on the use of our proprietary SBS biochemistry. In SBS, single stranded DNA is extended from 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 cycle 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, and the base itself can be inferred. Once this is done, an additional step removes both the fluorescence and the blocking group that had prevented further extension of the second strand. This allows another base to be added, and the cycle can then be repeated. Our technology is capable of generating over 100 billion bases of DNA sequence from 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 subject of significant intellectual property owned by us.
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
 
We have developed a proprietary array technology that enables the large-scale analysis of genetic variation and biological function. Our BeadArray technology combines microscopic beads and a substrate in a simple, proprietary manufacturing process to produce arrays that can perform many assays simultaneously. Our BeadArray technology providessimultaneously, enabling large-scale analysis of genetic variation and biological function in a unique combination of high throughput,high-throughput, cost effectiveness,effective, and flexibility.flexible manner. We achieve high throughputhigh-throughput with a high density of test sites per array, and we are able to format arrays either in a pattern arranged to match the wells of standard microtiter plates or in various configurations in the format of standard microscope slides. We seek to maximize cost effectiveness by reducing consumption of expensive reagents 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 these features have enabled our BeadArray technology to become a leading platform for the emerging high-growth market of SNP genotyping and expect they will enablehave allowed us to becomebe a key player in the gene expression market.
 
Our proprietary BeadArray technology combines microwells etched into a substrate and specially preparedconsists of 2-micron silica beads that self-assemble into microwells etched into an array.array substrate. We have deployed our BeadArray technology in two different array formats, the Array Matrix and the BeadChip. Our first bead-basedbead based product was the Array Matrix, which incorporates fiber optic bundles. The fiber optic bundles which we cut into lengths of less than one inch, are manufactured to our specifications. Each bundle is comprised of approximately 50,000 individual fibers, andwith 96 of these bundles are placed into an aluminum plate which formsto 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 fabricated in microscope slide-shaped sizesslide-size silicon wafers with varying numbers of sample sites per slide. Both formatsBeadChips are chemically etched to create tens to hundreds of thousandsmillions of wells for each sample site.
 
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. For example, we create a batch of SNP sensors by attaching a particular DNA sequence, or oligo, to each bead in the batch. We combine batches of coated beads to form a pool specific to the type of array we intend to create. A bead pool one milliliter in volume contains sufficient beads to produce thousands of arrays.
 
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 tens of thousands of beads in the wells comprise our individual arrays. Because the beads assemble randomly into the wells, we perform a final procedure called ’decoding’“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. We believe we are the only microarray company to provide this level of quality control in the industry.
 
An experiment is performed by preparing a sample, such as DNA, from a patient, and introducing it to the array. The design features of our Array Matrix allow it to be simply dipped into a solution containing the sample, whereas our BeadChip allows processing of samples on a slide-sized platform. The molecules in the sample bind to their matching molecules on the coated bead. Thesebeads. The molecules in either the sample or on the bead are labeled with a fluorescent dye either before or after the binding. The BeadArray Reader detects the fluorescent dyebinding, which can be detected by shining a laser on the fiber optic bundle or on the BeadChip. This allows the detection of the molecules resulting in a quantitative analysis of the sample.

Sequencing Technology
Our DNA sequencing technology, acquired as part of the Solexa merger that was completed on January 26, 2007, is based on the use of oursequencing-by-synthesis (SBS) biochemistry. In SBS, single stranded DNA is extended from a priming site, one base at a time, using reversible terminator nucleotides. These are DNA bases which can be added to a growing second strand, but which initially cannot be further extended. This means that at each cycle of the chemistry, only one base can be added. Each base which is added includes a fluorescent label which is specific to the particular base. Thus following incorporation, the fluorescence can be imaged, its color determined, and the base itself can be inferred. Once this is done, an additional step removes both the fluorescence and the block that had prevented further extension of the second strand. This allows another base to be added, and the cycle can be repeated. We have shown data in which this cycle is repeated up to 50 times, thus determining DNA sequences which are up to 50 bases long. This may well increase in the future as we further develop this technology. The reversible terminator bases which we use are novel synthetic molecules which we manufacture. They are not well incorporated by naturally occurring polymerases, so we have also developed proprietary enzymes for this purpose. Both the nucleotides and enzymes are the subject of significant intellectual property.
In our DNA sequencing systems, we apply the SBS biochemistry on microscopic islands of DNA. These are called DNA clusters. Each cluster starts as a single DNA molecule, 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 500 to 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 though, tens 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 electronic imaging.
 
VeraCode Technology
 
The BeadArray technology is most effective in applications which require mid- to high levels of multiplexing from low to high levels of throughput. Multiplexing refers to the number of individual pieces of information that are simultaneously extracted from one sample. We believe the molecular diagnostics market will require systems which are extremely high throughput and cost effective in the mid- to low-multiplex range. To address this market, we acquired theOur proprietary VeraCode technology through our acquisitionplatform leverages the power of CyVera Corporation in April 2005. Based on digitally encoded microbeads,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. We began shippingAt the BeadXpress System, which usesheart of the VeraCode technology duringare 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 first quarterspecific analyte or genotype of 2007, alonginterest 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 assayshundred. 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 system. We believe that this systemtime to achieve results. This technology enables lower multiplex genotyping, gene expressionus to serve a number of markets including research, agriculture, forensics, pharmaceuticals, and protein based assays. In the research market, we expect our customers to utilize our BeadArray technology for their higher multiplex projects and then move to our BeadXpress system for their lower multiplex projects utilizing the same assays.molecular diagnostics.
 
Oligator Technology
Genomic applications require many different short pieces of DNA that can be made synthetically, called oligos. We have developed our proprietary Oligator technology for the parallel synthesis of many different oligos to meet the requirements of large-scale genomics applications. We believe that our Oligator technology is substantially more cost effective and provides significantly higher throughput than available commercial alternatives. Our synthesis machines are computer controlled and utilize many robotic processes to minimize the amount of labor used in the manufacturing process. In 2005, we implemented our fourth-generation Oligator technology, which is capable of manufacturing over 13,000 different oligos per run. This was an improvement over prior generations of technology where we could only manufacture approximately 3,000 oligos per run. This increase in scale was necessary to enable us to


6


support the manufacture of oligos under our collaboration with Invitrogen as well as to support our increased internal need for oligos, a critical component of our BeadArray technology, for product sales and new product development.
Key Advantages of Our Technology
We believe that our technology provides distinct advantages, in a variety of applications, over competing technologies, by creating cost-effective, highly miniaturized arrays with the following characteristics:
High Throughput.  The miniaturization of our BeadArray technology provides very high information content per unit area. To increase sample throughput, we have formatted our array matrix in a pattern arranged to match the wells of standard microtiter plates, allowing throughput levels of up to nearly 150,000 unique assays per microtiter plate, and we use laboratory robotics to speed process time. Similarly, we have patterned our whole-genome expression BeadChips to support up to 48,000 gene expression assays for six samples with each BeadChip, and our whole-genome genotyping BeadChips to support over 1,000,000 genotypes with each BeadChip. Our Infinium and GoldenGate assays are supported by full automation and LIMS to address high throughput laboratories. Our Genome Analyzer can analyze the DNA sequences of tens of millions of clusters at one time.
Cost Effectiveness.  Our array products substantially reduce the cost of our customers’ experiments as a result of our proprietary manufacturing process and our ability to capitalize on cost reductions generated by advances in fiber optics, plasma etching processes, digital imaging and bead chemistry. In addition, our products require smaller reagent volumes than other array technologies, thereby reducing reagent costs for our customers. Our Oligator technology further reduces reagent costs, as well as reducing our cost of coating beads used in our BeadArray and VeraCode technologies. We believe the Genome Analyzer allows DNA sequencing at 1/100th of the cost of conventional capillary instruments.
Flexibility.  We are able to offer flexible solutions to our customers based on our ability to attach different kinds of molecules, including DNA, RNA, proteins and other chemicals, to our beads. In addition, we can have BeadChips manufactured in multiple shapes and sizes with wells organized in various arrangements to optimize them for different markets and market segments. In combination, the use of beads and etched wells provides the flexibility and scalability for our BeadArray technology to be tailored to perform many applications in many different market segments, from drug discovery to diagnostics. Our Oligator technology allows us to manufacture a wide diversity of lengths and quantities of oligos. DNA sequences determined with our Genome Analyzer can be used to identify larger DNA or RNA molecules from which the sequences have been derived, and can also be used for a series of applications based on tag sequencing, including digital gene expression analysis and microRNA discovery and quantification.
Quality and Reproducibility.  The quality of our products is dependent upon each element in the system — the array, the assay used to perform the experiment and the instrumentation and software used to capture the results. Each array is manufactured with a high density of beads, which enables us to have multiple copies of each individual bead type. We measure the copies simultaneously and combine them into one data point. This allows us to make a comparison of each bead against its own population of identical beads, which permits the statistical calculation of a more reliable and accurate value for each data point. Finally, the manufacture of the array includes a proprietary decoding step that also functions as a quality control test of every bead on every array, improving the overall quality of the data. When we develop the assays used with our products, we focus on performance, cost and ease of use. By developing assays that are easy to use, we can reduce the potential for the introduction of error into the experiment. We believe that this enables researchers to obtain high quality and reproducible data from their experiments. Additionally, we manufacture substantially all of the reagents used in our assays, allowing us to control the quality of the product delivered to the customer.

Our StrategyProducts
 
Our goal isUsing our proprietary technologies, our products give our customers the ability to make our BeadArray, BeadXpressanalyze the genome at any level of complexity from whole genome sequencing to low multiplex assays. This enables us to serve a number of markets, including research, agriculture, forensics, pharmaceuticals, and Genome Analyzer platforms the industry standard for products and services addressing the genetic analysis markets. We plan to achieve this by:
• focusing on emerging high-growth markets;
• seek out new and complimentary technologies;
• expanding our technologies into multiple product lines, applications and market segments; and
• strengthening our technological leadership.
Products and Services
molecular diagnostics. The first implementationmajority of our BeadArray technology, the Array Matrix, is a disposable matrix with 96 fiber optic bundles arranged in a pattern that matches the standard 96-well microtiter plate. Each fiber optic bundle performs more than 1,500 unique assays. The BeadChip, introduced in 2003, is fabricated in multiple configurations to support multiple applicationsproduct sales consist of instruments and scanning technologies.
We have provided genotyping services using our proprietary BeadArray technology since 2001. In addition, we have developed our first genotyping and gene expression productsconsumables based on this technology. These products include disposable Array Matricesthese various technologies. For the fiscal years ended January 3, 2010, December 28, 2008, and BeadChips, GoldenGateDecember 30, 2007, instrument sales comprised 34%, 32%, and Infinium reagent kits for SNP genotyping, BeadArray Reader scanning instruments33%, respectively, of total revenues, and an evolving portfolioconsumable sales represented 59%, 58%, and 53%, respectively, of custom and standard gene expression products.
SNP Genotyping
In 2001, we introduced the first commercial application of our BeadArray technology by launching our SNP genotyping services product line. Since this launch, we have had peak days in which we operated at 185 million genotypes per day. To our knowledge, no other genotyping platform can achieve comparable levels of throughput while delivering such high accuracy and low cost.
We designed our first consumable BeadArray product, the Array Matrix, for SNP genotyping. The Array Matrix uses a universal format that allows it to analyze any set of SNPs. We have also developed reagent kits based on GoldenGate assay protocols and the BeadArray Reader, a laser scanner, which is used to read our array products.
The BeadStation, a flexible and scalable system for performing genotyping, was initially commercialized in late 2003. The system currently includes our BeadArray Reader and genotypingand/or gene expression analysis software. Depending on throughput and automation requirements, our customers can select the system configuration to best meet their needs. For production-scale throughput, multiple BeadStations combined with LIMS, standard operating procedures, and analytical software and fluid handling robotics can be configured to produce millions of genotypes per day. Scientists and researchers can perform genotyping, gene expression, methylation, and copy number variation (CNV) analysis with these products.
In 2006, we introduced several new SNP genotyping products, including the HumanHap family of BeadChips, for genome-wide disease association studies. This family of BeadChips enables researchers to interrogate more than 1,000,000 SNP markers for associated studies. We believe our BeadChips provide the most comprehensive genomic coverage and highest data quality of any whole-genome genotyping product currently available. Through an application called Copy Number Polymorphisms, the HumanHap family of BeadChips also provides high-resolution information on amplifications, deletions and loss of heterozygosity throughout the genome, abnormalities common in cancers and congenital diseases. In addition, we announced additional standard panels in the first quarter of 2006, including mouse linkage and cancer panels.

Also, in 2006, we began shipment of the iSelect Infinium genotyping product line used for focused content applications. With this product, customers can create a custom array of up to 60,000 SNP markers per sample with 12 samples per chip.
During the fourth quarter of 2006, we introduced and began shipping the HumanHap300-Duo and the HumanHap300-Duo+ Genotyping BeadChips, as well as the RatRef-12 Expression BeadChip. The HumanHap300-Duo allows researchers to analyze two samples simultaneously, with over 634,000 total tag SNPs on a single BeadChip. The HumanHap300-Duo+ allows for the addition of 60,000 custom SNP loci to the base product, enabling researchers to enrich that product with SNPs of interest in any genomic region. The RatRef-12 Expression BeadChip enables analysis of 12 samples in parallel on a single BeadChip. Content for this BeadChip is derived from the NCBI RefSeq database (Release 16), with over 22,000 rat transcripts represented. By allowing for multiple samples on the same BeadChip, we believe we have minimized chip to chip variability and enhanced data quality.
In 2007, we announced the following key new product developments associated with SNP Genotyping:
• Human 1M DNA Analysis BeadChip.  This product combines an unprecedented level of content for both whole-genome and CNV analysis, along with additional unique, high-value genomic regions of interest — all on a single microarray chip. Shipments of the Human 1M DNA Analysis BeadChip began during the second quarter of 2007.
• HumanCNV370-Duo BeadChip.  The HumanCNV370-Duo enables researchers to analyze two samples simultaneously and access novel content for detecting disease-relevant CNV regions. Shipments of the HumanCNV370-Duo BeadChip began during the second quarter of 2007.
• HumanHap550-Duo BeadChip.  The HumanHap550-Duo provides the same content as our HumanHap550 BeadChip in a dual-format, resulting in significantly greater throughput and lower costs per sample. The HumanHap550-Duo contains more than 550,000 SNPs, selected based on a novel tag SNP approach. Shipments of the HumanHap550-Duo BeadChip began during the third quarter of 2007.
During 2008, we introduced two new products for DNA analysis: the Infinium High-Density (HD) Human1M-Duo (two samples per chip) and the Human610-Quad (four samples per chip), featuring up to 2.3 million SNPs per BeadChip. The new Infinium HD product line doubles sample throughput and reduces DNA input requirements by as much as 70 percent. The Infinium HD products also offer, what we believe is, enhanced signal discrimination and a new SNP calling algorithm. First customer shipments of the Human610-Quad and Human1M-Duo BeadChips are expected in the first and second quarter of 2008, respectively.
Gene Expression Profiling
With the addition of application specific accessory kits, our production-scale BeadStations are capable of performing a growing number of applications, including gene expression profiling.
In 2003, we introduced our focused set gene expression products on both the Array Matrix and BeadChip platforms. Our system includes a BeadArray Reader for imaging Array Matrices and BeadChips, a hybridization chamber and software for data extraction.
In 2005, we began shipment of the Human-6 and HumanRef-8 Expression BeadChip products. Both products allow large-scale expression profiling of multiple samples on a single chip and are imaged using our BeadArray Reader. The Human-6 BeadChip is designed to analyze six discrete whole-human-genome samples on one chip, interrogating in each sample approximately 48,000 transcripts from the estimated 30,000 genes in the human genome. The HumanRef-8 BeadChip product analyzes eight samples in parallel against 24,000 transcripts from the roughly 22,000 genes represented in the consensus RefSeq database, a well-characterized whole-genome subset used broadly in genetic analysis. We believe these gene expression BeadChips have dramatically reduced the cost of whole-genomerevenues.

expression analysis, allowing researchers to expand the scale and reproducibility of large-scale biological experimentation.
In 2006,Our major products, which we began shipment of the RatRef-12, which analyzes twelve samples in parallel against 22,226 transcripts from the roughly 21,910 genes represented in the RefSeq database, release 16.
In 2007, we launched the next versions of the Human and Mouse arrays, taking advantage of the updated content of the RefSeq and the UniGene databases could provide. We also expanded our product breadth and released our first microRNA arrays for both human and mouse. To keep up with the ever changing needs of the market, we have invested in the future with new, innovative technologies, acquired from the Solexa acquisition, to provide our customers with what we believe is the broadest portfolio of gene expression technologies available. We believe Digital Gene Expression (DGE) is a revolutionary approach to expression analysis. Driven by sequencing technology, DGE generates genome-wide expression profiles through sequencing, not hybridization. We believe this unique method provides 100 times the amount of data of other methods. It can provide more than one billion bases of data in a single run, at 1% of the cost of traditional Sanger sequencing. Using DGE, researchers can:
• quickly discover novel RNAs in any species;
• accurately quantify low-abundance RNA;
• confidently analyze small and non-coding RNA, as well as transcriptomes; and
• independently validate microarray data.
Instrumentation
The BeadArray Reader, an instrument we developed, is a key component of our BeadStation. This scanning equipment uses a laser to read the results of experiments that are captured on our arrays and was designedexpect to be used in all areas of genetic analysis that use our Array Matrices and BeadChips. In the second quarter of 2006, we beganavailable for shipment of the AutoLoader, which automates BeadChip loading and scanning and increases lab throughput. The Autoloader is designed to support up to two BeadArray Readers simultaneously for unattended operation.
During the first quarter of 2007, we began shipment of the Genome Analyzer. This product can generate more than one billion bases of data in a single run using a massively parallel sequencing approach. The system leverages Solexasequencing-by-synthesis technology and novel reversible terminator chemistry, optimized to achieve what we believe are unprecedented levels of cost effectiveness and throughput.
Also, during the first quarter of 2007, we began shipment of2010, include the BeadXpress System. This system is a high-throughput, dual-color laser detection system developed using the VeraCode digital microbead technology. It enables scanning of a broad range of multiplexed assays and can take researchers from biomarker validation and focused studies to the development of molecular diagnostics.following:

We are also focused on continuing to enhance the quality and manufacturing yield of our Array MatricesBeadChips and BeadChipsflow 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. In addition, we have implemented information management systems for many of our manufacturing and services operations to manage all aspects of material and sample use. 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 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 use alternative reagents. 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 expect that our products and services will provide significant advantages over products and services currently available from other sources, we expect to encounter intense competition from other companies that offer products and services for the sequencing, SNP genotyping, gene expression, and sequencingmolecular diagnostics markets. These include companies such as Affymetrix, Inc.; Agilent Applera Corporation, Applied Biosystems,Technologies, Inc.; Beckman Coulter, Inc.; Complete Genomics, Fluidigm, GE Corp.,Inc.; General Electric Company; Helicos BioSciences Corporation; Life Technologies Corporation; Luminex Corporation; Pacific Biosciences, Perlegen Sciences,Inc.; Roche Diagnostics Corp.; Sequenom, Inc.; and Third Wave Technologies.Qiagen N.V. 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 need to 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


13


order to effectively compete with these companies, we will need to demonstrate that our products have superior throughput, cost, and accuracy advantages over the competing products. Rapid technological development may result in our products or technologies becoming obsolete. Products offered by us could be made obsolete either by less expensive or more effective products based on similar or other technologies. Although we believe that our technology and products will offer advantages that will enable us to compete effectively with these companies, we cannot assure you that we will be successful.
 
Segment and Geographic Information
 
We operateDuring the first quarter of 2008, we reorganized our operating structure into two newly created business segments, Life Sciences and Diagnostics. Our Life Sciences Business Unit includes all products and services that are primarily related to the research market, namely the product lines based on our sequencing, BeadArray, and VeraCode technologies, and our Diagnostics Business Unit focuses on the emerging opportunity in one business segment formolecular diagnostics. During 2009, we had limited activity related to the development, manufactureDiagnostics Business Unit and commercialization of tools for genetic analysis. Our operations are treated as one segment as we only report operating results were reported on an aggregate basis to our chief operating decision maker, our Chief Executive Officer.the chief executive officer. Accordingly, we operated in one reportable segment during 2009.
 
During 2007, $159.1 million, or 43%,We currently sell our products to a number of our total revenue came from shipmentscustomers 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 million, or 48% of our total revenue, during 2009, compared to $81.5$293.2 million, or 44%51%, and $28.0$159.1 million, or 38%43%, in 20062008 and 2005,2007, respectively. Sales to territoriescustomers outside of the United States arewere generally denominated in U.S. dollars. In 2008, we reorganized our international structure 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. We expect that sales to international customers will continue to be an important and growing source of revenue. We have sales support resources in Western Europe and direct sales offices in Japan, Singapore and China. In addition, we have distributor relationships in various countries in the Pacific Rim region and Europe. See Note 13 of the Notes to Consolidated Financial Statements for further information concerning our foreign and domestic operations.
Backlog
Our backlog was $227.6 million and $113.0 million at January 3, 2010 and December 28, 2008, 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% of the backlog as of January 3, 2010 to be shipped within the fiscal year ending January 2, 2011. Although we generally recognize revenue at the time of shipment and transfer of title to a customer, we may be required to defer the recognition of revenue even after shipment 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 spendspending unused budget allocations before the end of the U.S. government’s fiscal year.
 
Environmental Matters
 
We are dedicatedcommitted to the protection of our employees and the environment. Our operations require the use of hazardous materials whichthat 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.
 
During 2007,Government Regulation
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 entered into a lease agreement with BioMed Realty Trust, Inc.expand our product line to expand into a new office buildingencompass products that are intended to be used for the diagnosis of disease, such as molecular diagnostic products, regulation by governmental authorities in San Diego, California. This new buildingthe United States and other countries will be LEED certified.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.


13


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 you 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 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.
Employees
 
As of December 30, 2007,January 3, 2010, we had a total of 1,041 employees, 195 of whom hold Ph.D. degrees. Ninety-seven of our employees with Ph.D. degrees are engaged in full-time research and development activities.1,781 employees. None of our employees are represented by a labor union. We consider our employee relations to be positive.

ITEM 1A.  Risk Factors.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.
 
We expectface intense competition, in our target markets, which could render our products obsolete, result in significant price reductions, or substantially limit the volume of products that we sell. This would limit our ability to compete and maintain profitability. If we cannot continuously develop and commercialize new products, our revenue may not grow as intended.
 
We compete with life sciences companies that design, manufacture, and market instrumentsproducts for analysis of genetic variation and biological function and other applications using technologies such as two-dimensional electrophoresis, capillary electrophoresis, mass spectrometry, flow cytometry, microfluidics, nanotechnology, next-generation DNA sequencing and mechanically deposited, inkjet and photolithographic arrays.a wide-range of competing technologies. We anticipate that we will continue to face increased competition in the future as existing companies develop new or


15


improved products and as new companies enter the market with new technologies. The markets for our products are characterized by rapidly changing technology, evolving industry standards, changes in customer needs, emerging competition, new product introductions and strong price competition. For example, prices per data point for genotyping have fallen significantly over the last two years and we anticipate that prices will continue to fall. 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. For example, duringWe 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 third quarter of fiscal 2007, Applied Biosystems Group, a business segment of Applera Corporation, launched the SOLIDtm System,its next generation sequencing technology. Ifextent 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 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, 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 seek or be able to convert raw genetic data into medically valuable information through the analysis of genetic variation and biological function. 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 sales and operating earnings, and ultimately our reputation, could be negatively impacted.
In the course of conducting our business, we must adequately address quality issues associated with our products and services, including defects in our engineering, design, and manufacturing processes, as well as defects in third-party components included in our products. Because our instruments and reagents are highly complex, the occurrence of defects may increase as we continue to introduce new 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, 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 as well as our financial results.


1516


If we do not successfully manage the development and launch of new products or services, including product transitions, our financial results could be adversely affected.
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 develop enhancementsdeliver 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 it may cause us to delay our 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 technology and rapidly deployexisting 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 product offerings,products could adversely affect our business, financial condition, andor results of operations will suffer.operations.
 
OurIf we are unable to increase our manufacturing capacity and develop and maintain operation of our manufacturing capability, we may limitnot be able to launch or support our ability to sell our products.products in a timely manner, or at all.
 
We continue to ramp upincrease our 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 business plan in 2008 and 2009,for 2010, 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 yields.of certain products. Due to the intricate nature of manufacturing 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(or to produce them economically,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; Singapore; and Little Chesterford, 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 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.
WeOur acquisitions expose us to risks that could adversely affect our business, and we may encounter difficulties in managing our growth. These difficulties could impair our profitability.not achieve the anticipated benefits of acquisitions of businesses or technologies.
 
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


17


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;
• 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.
Unfavorable global economic conditions could adversely affect our business, financial condition, or results of operations.
Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. The recent global financial crisis caused extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn, such as the recent global financial


18


crisis, could result in a variety of risks to our business, including, in particular, reductions or delays in planned improvements to healthcare systems, research and development funding, and purchases of our products and services, or cost-containment efforts by governments and private organizations that could adversely affect 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:
• 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 adversely affect 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 for the year ended January 3, 2010 and with the number of employees increasing from 375 to 1,781 during the same period. We expect to continue to experience rapid and substantial growth in order to achieve our operating plans, which willplans. The rapid expansion of our business and addition of new personnel may place a strain on our humanmanagement and capital resources. If we are unable to manage this growth effectively, our profitability could suffer.operational systems. Our ability to effectively manage our operations and growth effectively 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.employees on a global basis.

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. WeIn 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 products or technologies.
Our planned activities will require additional expertise in specific industries and areas applicable to the products developed through our technologies, including the life sciences and healthcare industries. Thus, we will need to add new personnel, including management, and develop the expertise of existing management. The failure to do so could impair the growth of our business.

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.
If we are unable to developDoing business internationally creates operational and maintain operation offinancial risks for our manufacturing capability, we may not be able to launch or support our products in a timely manner, or at all.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 currently manufactureare focused on expanding our international operations in a limited number of locations. Ourkey markets. We have sales offices located internationally throughout Europe and the Asia-Pacific region, as well as manufacturing facilities are located in San Diego and Hayward, California and Little Chesterford, United Kingdom. We are in the process of expanding our manufacturing operations into Singapore, a country in which we have no past manufacturing experience. These areas are subject to natural disasters such as earthquakes or floods. If a natural disaster were to significantly damage oneUnited Kingdom and Singapore. During 2009, the majority of our facilities or if other eventssales to international customers and purchases of raw materials from international suppliers were denominated in U.S. dollars. Shipments to causecustomers outside the United States comprised 48%, 51%, and 43% of our operationstotal revenue for the years ended January 3, 2010, December 28, 2008, and December 30, 2007, respectively. We intend to fail, these events could prevent us from developingcontinue to expand our international presence by selling to customers located outside of the United States and manufacturing our products and services.we expect the total amount ofnon-U.S. sales to continue to grow.

Our costs of materials from achieving our expected shipmentsinternational suppliers may increase if in any given period.
Our sales, marketing and technical support organization may limit our ability to sell our products.
We currently have fewer resources available for sales and marketing and technical support services compared to some of our primary competitors. In order to effectively commercialize our sequencing, genotyping and gene expression systems and other products to follow, we will need to expand our sales, marketing and technical support staff both domestically and internationally. We may not be successful in establishing or maintaining either a direct sales force or distribution arrangements to market our products and services. In addition, we compete primarilycontinue doing business with much larger companies that have larger sales and distribution staffs and a significant installed base of products in place, andus they raise their prices as the efforts from a limited sales and marketing force may not be sufficient to build the market acceptance of our products required to support continued growth of our business.
Negative conditions in the global credit markets may impair the liquidity of a portion of our investment portfolio.
Our investment securities consist of U.S. dollar-based short maturity mutual funds, commercial paper, corporate bonds, treasury notes, auction rate securities and municipal bonds. As of December 30, 2007, our short-term investments included $14.7 million of high-grade (AAA rated) auction rate securities issued primarily by municipalities and universities. The recent negative conditions in the global credit markets have prevented some investors from liquidating their holdings, including their holdings of auction rate securities. In February 2008, we were informed that there was insufficient demand at auction for four of our high-grade auction rate securities, representing approximately $10.7 million. As a result, these affected securities are currently not liquid, and we could be required to hold them until they are redeemed by the issuer or to maturity. We may experience a similar situation with our remaining auction rate securities. In the event we need to access the funds that are in an illiquid state, we will not be able to do so without a loss of principal, until a future auction on these investments is successful, the securities are redeemed by the issuer or they mature. At this time, management has not obtained sufficient evidence to conclude that these investments are impaired or that they will not be settled in the short term, although the market for these investments is presently uncertain. If the credit ratings of the security issuers deteriorate and any decline in market value is determined to be other-than-temporary, we would adjust the carrying value of the investment through an impairment charge.

WeU.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 encounter difficulties in integrating acquisitions thatcontinue, which could adversely affect our business, specifically the effective launch and customer acceptance of new technology platforms.
We acquired Solexa in January 2007 and CyVera in April 2005 and we may in the future acquire technology, productsfinancial condition, or businesses related to our current or future business. We have limited experience in acquisition activities and may have to devote substantial time and resources in order to complete acquisitions. Further, these potential acquisitions entail risks, uncertainties and potential disruptions to our business. For example, we may not be able to successfully integrate a company’s operations, technologies, products and services, information systems and personnel into our business. An acquisition may further strain our existing financial and managerial resources, and divert management’s attention away from our other business concerns.
In connection with these acquisitions, we assumed certain liabilities and hired certain employees, which is expected to continue to result in an increase in our research and development expenses and capital expenditures. There may also be unanticipated costs and liabilities associated with an acquisition that could adversely affect our operating results. To finance any acquisitions, we may choose to issue shares of our common stock as consideration, which could result in dilution to our stockholders. Additionally, an acquisition may have a substantial negative impact on near-term expected financial results.
The success of the Solexa acquisition depends, in part, on our ability to realize the anticipated synergies, growth opportunities and cost savings from integrating Solexa’s businesses with our businesses. Our success in realizing these benefits and the timing of this realization depends upon the continued successful integration of the operations of Solexa. The integration of two independent companies is a complex, costly and time-consuming process. In addition, Solexa continues to operate at separate sites. Geographic integration in whole or in part could result in the loss of key employees, diversion of each company’s management’s attention, the disruption or interruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with customers and employees or our ability to achieve the anticipated benefits of the acquisition, or could reduce our earnings or otherwise adversely affect the business and financial results of the combined company.operations.
 
The combined company may failWe are subject to realizerisks related to taxation in multiple jurisdictions and the anticipated benefitspossible loss of the acquisition as a result oftax deduction on our failure to achieve anticipated revenue growth following the acquisition.
For various reasons, including significant competition, low market acceptance or market growth, and lack of technology advantage, revenue recognized from the Solexa acquisition may not grow as anticipated and if so, we may not realize the expected value from this transaction.
If we are unable to find third-party manufacturers to manufacture components of our products, we may not be able to launch or support our products in a timely manner, or at all.
The nature of our products requires customized components that currently are available from a limited number of sources. For example, we currently use multiple components in our products that are single-sourced. If we are unable to secure a sufficient supply of those or other product components, we will be unable 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, for 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.
Changes in our effective income tax rate could impact our profitability.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(including share-based compensation,compensation), changes in our future levels of research and development spending, mergers and acquisitions, andor 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 adequatelyeffectively protect our proprietary technologies could harm our competitive position.
 
Our success will depend in partdepends 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 protectingestablishing and enforcing their proprietary rights abroad.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 abroad.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 andor 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 isthe 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 additional 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 secretsecrets and proprietary know-how protection for our confidential and proprietary information. Weinformation, and we have taken security measures to protect our confidentialthis 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. Nevertheless,There can be no assurance that any confidentiality agreements that we have with our employees, collaborators, orand consultants may still disclose our confidential information, and we may not otherwise be able to effectively protectwill provide meaningful protection for our trade secrets. Accordingly, others may gain access to oursecrets and confidential information or maywill 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 develop substantially equivalent information or techniques.developed by competitors.

Litigation, or 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 or impact our stock price.services.
 
Our commercial success depends, in part, on our non-infringement of the patents or proprietary rights of third parties and on our ability to protect our own intellectual property.parties. Third parties have asserted orand may in the future assert that we are employing their proprietary technology without authorization. As we


19


enter new markets, we expect that competitors will likely assertclaim 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 a materialan 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, andor sell products, and could result in the award of substantial damages against us. In the event of a successful infringement claim of infringement 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 materiallyadversely affect our ability to grow andor maintain profitability.
 
WeOur 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 amount of indebtedness. Wedelays in obtaining, regulatory approvals for molecular diagnostic products that we develop, we may not be able to make payments onlaunch 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 indebtedness,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.

Our operating results may vary significantly from period to period, and we may incur additional indebtedness in the future, which could adversely affect our operation and profitability.
In February 2007, we issued $400 million of 0.625% Convertible Senior Notes due February 2014. The notes bear interest semi-annually, mature on February 15, 2014 and obligate us to repurchase the notes at the option of the holders if a “designated event” (as defined in the indenture for the notes), such as certain merger transactions involving us, occurs. In addition, upon conversion of the notes, we must pay in cash the principal portion of the notes being converted. Our ability to make payments on the notes will depend on our future operating performance and our ability to generate cash and may also depend on our ability to obtain additional debt or equity financing. We may need to use our cash to pay principal and interest on our debt, which will reduce the funds available to fund our research and development programs, strategic initiatives and working capital requirements. Our ability to generate sufficient operating cash flow to service the notes and fund our operating requirements will depend on our continued ability to commercialize new products and expand our manufacturing capabilities. Our debt service obligations increase our vulnerabilities to competitive pressures, because our competitors may be less leveraged than we are. If we are unable to generate sufficient operating cash flow to service our indebtedness and fund our operating requirements, we may be forced to reduce our development programs or seek additional debt or equity financing, which may not be availableable to us on satisfactory terms, or at all, or may dilute the interests of our existing stockholders. Our level of indebtedness may make us more vulnerable to economic or industry downturns. If we incur new indebtedness, the risks relating to our business and our ability to service our indebtedness will intensify.
We expect that our results of operations will fluctuate. This fluctuation could cause our stock price to decline.sustain operating profitability.
 
Our revenue is subject to fluctuations due to the timing of sales of high-value products and services, projects,the effects of new product launches and related promotions, 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 areis relatively fixed, including expenses for facilities, equipment, and personnel. In addition, we expect operating expenses to continue to increase significantly in absolute dollars.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


20


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-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 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.
We have only recently achieved annual operating profitability.Changes in accounting standards and subjective assumptions, estimates, and judgments by management related to complex accounting matters could significantly affect our financial results or financial condition.
 
PriorGenerally accepted accounting principles and related accounting pronouncements, implementation guidelines, and interpretations with regard to 2006, we had incurred net losses each year since our inception, and in 2007 we reported a net losswide range of $278.4 million, reflecting significant charges associated with our acquisition of Solexa in January 2007 and the settlement of our litigation with Affymetrix. As of December 30, 2007, our accumulated deficit was $383.0 million. Our ability to regain and sustain annual profitability will depend, in part, on the rate of growth, if any, of our revenue and on the level of our expenses. Non-cash stock-based compensation expense and expenses relatedmatters that are relevant to our acquisition of Solexabusiness, such as revenue recognition, asset impairment and fair value determinations, inventories, business combinations and intangible asset valuations, and litigation, are also likely to continue to adversely affecthighly 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 future profitability. We expect to continue incurring significant expenses related to research and development, sales and marketing efforts to commercialize our products and the continued development of our manufacturing capabilities.reported or expected financial performance or financial condition. In addition, we expect thatthe timing of large orders can have a significant effect on our researchbusiness 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. Even if we regain profitability, we may not be ableoperating results from quarter to increase profitability on a quarterly basis.quarter.

Approximately 43%, 44%Genetic testing has raised ethical, legal, and 38%social issues regarding privacy and the appropriate uses of the resulting information. Governmental authorities could, for social or other purposes, call for limits on or

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 revenuetechnology for certain applications or reduce the years ended December 30, 2007, December 31, 2006 and January 1, 2006, respectively, was derived from shipments to customers outside the United States. We intend to continue to expandpotential markets for our international presence and export sales to international customers and we expect the total amounttechnology, either ofnon-U.S. sales to continue to grow. Export sales entail a variety of risks, including:
• currency exchange fluctuations;
• unexpected changes in legislative or regulatory requirements of foreign countries into which we import 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.
In addition, sales to international customers typically result in longer payment cycles and greater difficulty in accounts receivable collection. We are also subject to general geopolitical risks, such as political, social and economic instability and changes in diplomatic and trade relations. One or more of these factors could have a materialan adverse effect on our business, financial condition, and operating results.
Our success depends upon the continued emergence and growthor results of markets for analysis of genetic variation and biological function.
We design our products primarily for applications in the life sciences and pharmaceutical industries. The usefulness of our technology 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, SNP 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 seek or be able to convert raw genetic data into medically valuable information through the analysis of genetic variation and biological function. In


21


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 annual profitability.
The accounting method for our convertible debt securities may be subject to change.
A convertible debt security providing for shareand/or cash settlement of the conversion value and meeting specified requirements under Emerging Issues Task Force (EITF) IssueNo. 00-19,Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, including our outstanding convertible debt securities, is currently classified in its entirety as debt under U.S. generally accepted accounting principles. No portion of the carrying value of such a security related to the conversion option indexed to the issuer’s stock is classified as equity. In addition, interest expense is recognized at the stated coupon rate. The coupon rate of interest for convertible debt securities, including our convertible debt securities, is typically lower than an issuer would be required to pay for nonconvertible debt with otherwise similar terms.
The EITF recently considered whether the accounting for cash settled convertible debt securities, which are convertible debt securities that require or permit settlement in cash either in whole or in part upon conversion should be changed, but was unable to reach a consensus and discontinued deliberations on this issue. Subsequently, in July 2007, the Financial Accounting Standards Board (FASB) voted unanimously to reconsider the current accounting for cash settled convertible debt securities, which includes our convertible debt securities. In August 2007, the FASB exposed for public comment a proposed FASB Staff Position (FSP) that would change the method of accounting for such securities and would require the proposed method to be retrospectively applied. The FASB began its redeliberations of the guidance in that proposed FSP in January 2008. The FSP, if issued as proposed, would likely become effective for companies like us in the first quarter of 2009. Under this proposed method of accounting, the debt and equity components of our convertible debt securities would be bifurcated and accounted for separately in a manner that would result in recognizing interest on these securities at effective rates more comparable to what we would have incurred had we issued nonconvertible debt with otherwise similar terms. The equity component of our convertible debt securities would be included in thepaid-in-capital section of stockholders’ equity on our balance sheet and, accordingly, the initial carrying values of these debt securities would be reduced. Our net income for financial reporting purposes would be reduced by recognizing the accretion of the reduced carrying values of our convertible debt securities to their face amounts as additional non-cash interest expense. Therefore, if the proposed method of accounting for cash settled convertible debt securities is adopted by the FASB as described above, it would have an adverse impact on our past and future reported financial results. As the final guidance has not been issued, we cannot predict its ultimate outcome.
We also cannot predict any other changes in GAAP that may be made affecting accounting for convertible debt securities, some of which could have an adverse impact on our past or future reported financial results.operations.

Item 3.  Legal Proceedings.
 
In the recent past,From time to time, we incurred substantial costs in defending ourselves against patent infringement claimsare party to litigation and expect, going forward, to devote substantial financial and managerial resources to protect our intellectual property and to defend against any future claims asserted against us.
Affymetrix Litigation
On January 9, 2008, we resolved all our outstanding litigations with Affymetrix, Inc. (Affymetrix) by entering into a settlement agreement in which we 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 us, and we agreed to dismiss with prejudice our counterclaimsother legal proceedings in the relevant lawsuits. In exchange forordinary course, and incidental to the payment, Affymetrix agreed not to sue us or our affiliates or customers for making, using or selling anyconduct, of our current products, evolutions of those products or services related to

those products. In addition, Affymetrix agreed that, for four years, it will not sue us for making, using or selling our products or services that are based on future technology developments. The covenant not to sue covers all fields other than photolithography,business. While the process by which Affymetrix manufactures its arrays and a field in which we do not operate.
The January 2008 settlement resolved complaints Affymetrix had previously filed in the U.S. and abroad. Specifically, on July 26, 2004, Affymetrix had filed a complaint in the U.S. District Court for the District of Delaware alleging that the use, manufacture and sale of our BeadArray products and services, including our Array Matrix and BeadChip products, infringe six Affymetrix patents. At that time Affymetrix was also seeking an injunction against the saleresults of any products that would ultimately be determined to infringe these patents, unspecified monetary damages, interest and attorneys’ fees. Subsequently, on October 24, 2007, Affymetrix had filed complaints inlitigation or other legal proceedings are uncertain, management does not believe the U.S. District Court for the District of Delaware, in Regional Court in Düsseldorf (Germany), and in the High Court of Justice, Chancery Division — Patents Court in London (United Kingdom) alleging that the use, manufacture and sale of certain of our BeadArray products and services, including our Array Matrix and BeadChip products, infringe three U.S. patents and three European patents of Affymetrix. In its U.S. complaint filed in 2007, Affymetrix had also alleged that our sequencing technology, including the Genome Analyzer, infringes two Affymetrix U.S. patents. Affymetrix also sought an injunction against the saleultimate resolution of any products that would ultimately be determinedpending legal matters is likely to infringe these patents, unspecified monetary damages, interest and attorneys’ fees.
Former Employee Claim
On June 15, 2005,have a former employee, filed suit against us in the U.S. District Court for the Districtmaterial adverse effect on our financial position or results of Delaware seeking an order requiring us and the U.S. Patent and Trademark Office to correct the inventorship of certain of our patents and patent applications by adding the former employee as an inventor, alleging that we committed inequitable conduct and fraud in not naming him as an inventor, and seeking a judgment declaring certain of our patents and patent applications unenforceable, unspecified monetary damages and attorney’s fees. On January 30, 2008, this dispute was resolved to the mutual satisfaction of the parties by entering into a release and settlement agreement pursuant to which all claims pending in that litigation were dismissed with prejudice.
Applied Biosystems Litigation
On December 26, 2006, the Applied Biosystems Group of Applera Corporation (Applied Biosystems) filed suit in California Superior Court, Santa Clara County against Solexa (which we acquired on January 26, 2007). This State Court action is about the ownership of several patents assigned in 1995 to Solexa’s predecessor company (Lynx Therapeutics) by a former employee (Dr. Stephen Macevicz) who is the inventor of these patents and is named as a co-defendant in the suit. Lynx was originally a unit of Applied Biosystems but was spun out in 1992. On May 31, 2007, Applied Biosystems filed a second suit, this time against us, in the U.S. District Court for the Northern District of California. This second suit seeks a declaratory judgment of non-infringement of the Macevicz patents that are the subject of the State Court action mentioned above. Both suits were later consolidated in the U.S. District Court for the Northern District of California, San Francisco Division.
The Macevicz patents relate to methods for sequencing DNA using successive rounds of oligonucleotide probe ligation(Sequencing-by-Ligation). Our Genome Analyzer system uses a different technology called DNASequencing-by-Synthesis (SBS), which is not covered by any of these patents. In addition, the sequencing technology originally used by Lynx Therapeutics (called “MPSStm”) is not based on the methods covered by the Macevicz patents. In any event, we have never used MPSStm in our sequencing platform. Furthermore, we have no plans to use any of theSequencing-by-Ligation technologies covered by these patents. By these consolidated actions Applied Biosytems is seeking ownership of the Macevicz patents, unspecified costs and damages, and a declaration of non-infringement of these patents. Applied Biosystems is not asserting any claim for patent infringement against us.operations.

Business Overview
 
We are a leading developer, manufacturer, and marketer of integrated systems for the large scale analysis of genetic variation and biological function. Using our proprietary technologies, we provide a comprehensive line of products and services that currently serve the sequencing, genotyping, and gene expression markets. In the future,markets, and we expect to enter the market for molecular diagnostics. Our customers include leading genomic research centers, pharmaceutical companies, academic institutions, clinical research organizations, and biotechnology companies.
We develop and commercialize sequencing technologies used to perform a range of analyses, including de novo sequencing, whole genome re-sequencing, gene expression analysis, and small RNA analysis. Our product and service offerings also include leading-edge solutions for single-nucleotide polymorphism (SNP) genotyping, copy number variation (CNV), DNA methylation studies, gene expression profiling, and low-multiplex analysis of DNA, RNA, and protein. We believe we are the only company with genome-scale technology for sequencing, genotyping, and gene expression — the three cornerstones of modern genetic analysis.
Our tools provide researchers around the world with the performance, throughput, cost effectiveness, and flexibility necessary to performdetermine and analyze the billions of bits of genetic testsinformation 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 in 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.
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 April 2005,2009 we completedmade 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.
While these trends are important to understanding and evaluating our financial results, the other transactions, events and trends discussed in “Risk Factors” in Item 1A of this report may also materially impact our business operations and financial results.

Total revenue $666,324  $573,225  $93,099   16%
                 
Product revenue consists primarily of revenue from the sale of consumables and instruments.
Consumable revenue increased $57.6 million, or 17%, to $391.3 million for the year ended January 3, 2010 compared to $333.7 million for the year ended December 28, 2008. Microarray consumable revenue, which constituted more than half of our consumable 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%, driven by growth in the installed base of our Genome Analyzer systems and the progression of customer labs ramping to production scale. The increase was partially offset by a loss of sales related to a quality issue affecting our paired-end cluster kits that arose in September 2009 when some of our larger sequencing customers began experiencing higher than average error rates on the second read of their paired-end analysis. During the fourth quarter, we began shipping reformulated paired-end cluster kits at full capacity and cleared the related shipping backlog.
Revenue 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, 2008 primarily due to a $56.4 million, or 43%, increase in sales of our sequencing systems. During 2009 as compared to 2008 both units sold and average selling prices increased for our Genome Analyzer systems, which constitute a majority of sequencing instrument revenue. The increase in units sold was driven by increased demand for next generation sequencing and oursequencing-by-synthesis technology. The increase 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 was partially offset by a $16.4 million, or 30%, decrease in the sales of our microarray systems, which declined primarily due to customers delaying the start of new GWAS 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.

33


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 and the benefit of decreased costs associated with the reformulation of our sequencing kits launched at the end of the third quarter of 2008. The cost of sequencing instruments decreased as a percentage of related revenue due to production efficiencies and reduced material costs coupled with higher average selling prices.

Total operating expenses $316,953  $247,977  $68,976   28%
                 
The increase in research and development was driven primarily by a $22.9 million increase in personnel-related expenses, including salaries, non-cash stock-based compensation and benefits, a $10.4 million increase to non-personnel related expenses and an increase in outside services of $3.2 million attributable to consulting fees. These increases are primarily related to the growth in our efforts to optimize and commercialize our sequencing and BeadArray technologies.
The increase in selling, general and administrative expenses was driven by an increase of $26.6 million in personnel-related expenses associated with the growth of our business, including salaries, non-cash stock-based compensation and benefits.

Interest income decreased despite an increase in our average cash and investment balance due to an overall decline in interest rates during 2009. Interest expense increased due to the amortization of the discount on our convertible senior notes. Other income, net decreased due to a decrease of $1.5 million in gains on net foreign currency transactions, which was partially offset by a gain of $0.8 million on the conversion of a portion of our debt during the first quarter of 2009.

Provision for income taxes $41,844  $33,271  $8,573   26%
The aggregateincrease in the provision for income taxes was attributable to the increase in the consolidated income before income taxes. The effective tax rate decreased 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.
Comparison of Years Ended December 28, 2008 and December 30, 2007
Our 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 years ended December 28, 2008 and December 30, 2007 were both 52 weeks.

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 consumables was primarily attributable to the growth of our installed base of instruments and the progression of customer labs ramping to production scale.
Revenue 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 product and service and other revenue $205,624  $132,436  $73,188   55%
                 
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.

Operating Activities
Cash provided by operating activities for the year ended January 3, 2010 consists of net income of $72.3 million plus net non-cash adjustments of $113.5 million and an $11.3 million increase in net operating assets. The primary non-cash expenses added back to net income included share based compensation of $60.8 million and depreciation and amortization expense related to property and equipment, intangibles and the debt discount on our convertible notes totaling $51.5 million. The main drivers 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 1.526.2 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 paymentthe sale of approximately $2.3shares under our Employee Stock Purchase Plan and $39.3 million of CyVera’s liabilitiesincremental 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 closing.
On January 26, 2007,Company of $342.7 million, after deducting underwriting discounts and commissions and offering expenses. During the year ended December 28, 2008, we completed the acquisition of Solexa foralso repurchased approximately 13.13.1 million shares of our common stock. Solexa developsstock 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 commercializes genetic analysis technologiesoffering expenses, were approximately $390.3 million. We used $201.6 million of the net proceeds to performpurchase 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 primary source of our liquidity. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing and financing needs. Historically, we have issued debt and equity securities to finance our requirements to the extent that cash provided by operating activities was not sufficient to fund our needs. We may require additional funding in the future and our failure to raise capital on acceptable terms, when needed, could have a rangematerial adverse effect on our business.
At January 3, 2010, we had approximately $693.5 million in cash and short-term investments. Short-term investments include marketable securities and auction rate securities totaling $494.0 million and $54.9 million, respectively. Our marketable securities consist of analyses including whole genome resequencing, gene expressing analysisdebt securities in government sponsored entities, corporate debt securities and small RNA analysis.U.S treasury notes. We believedo not hold securities backed by mortgages. Our auction rate securities were issued primarily by municipalities and universities. The markets for auction rate securities effectively ceased when the vast majority 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 combined company isauction rate securities at par value to UBS AG (UBS) at our discretion during the only company with genome-scale technologyperiod 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 genotyping, gene expression and sequencing, the three cornerstones of modern genetic analysis.further information regarding our auction rate securities.
 
Our revenue isoutstanding 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 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. See Note 7 of Notes to Consolidated Financial Statements for further discussion of the terms of the convertible senior notes.
Our primary short-term needs for capital, which are subject to fluctuations due to the timing of sales of high-value products and service projects, the impact of seasonal spending patterns, the timing and size of research projects our customers perform, changes in overall spending levels in the life science industry and other unpredictable factors that may affect our customer ordering patterns. Any significant delays in the commercial launch or any lack or delay of commercial acceptance of new products, unfavorable sales trends in our existing product lines, or impacts from the other factors mentioned above, could adversely affect our revenue growth or cause a sequential decline in quarterly revenue. Due to the possibility of fluctuations in our revenue and net income or loss, we believe quarterly comparisons of our operating results are not a good indication of our future performance.change, include expenditures related to:
• potential strategic acquisitions and investments;

We expect that our product revenue and the resulting operating income, as well as the status of December 30, 2007,each of our accumulated deficit was $383.0 millionnew product development programs, will significantly impact our cash management decisions.
We anticipate that our current cash and total stockholders’ equity was $411.7 million.cash equivalents and income from operations will be sufficient to fund our operating needs in 2010, barring unforeseen circumstances. 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 lossesfuture 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.
Off-Balance Sheet Arrangements
We do not participate in any transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have principally occurred as a result of acquired in-process research and development charges of $303.4 million related to our acquisition of Solexa in 2007, the substantial resources requiredbeen established for the research, developmentpurpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

GeneralComparison of Years Ended January 3, 2010 and December 28, 2008
 
Our discussionfiscal year is the 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 analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles.September 30. The preparation of financial statements requires that management make estimates, assumptions and judgments with respect to the application of accounting policies that affect the reported amounts of assets, liabilities, revenue and expenses,year ended January 3, 2010 was 53 weeks and the disclosures of contingent assets and liabilities. Actual results could differ from those estimates.
Our significant accounting policies are described in Note 1 to our consolidated financial statements. Certain accounting policies are deemed critical if 1) they require an accounting estimate to be made based on assumptions that were highly uncertain at the time the estimateyear end December 28, 2008 was made, and 2) changes in the estimate that are reasonably likely to occur, or different estimates that we reasonably could have used would have a material effect on our consolidated financial statements.
Management has discussed the development and selection of these critical accounting policies with the Audit Committee of our Board of Directors, and the Audit Committee has reviewed the disclosure. In addition, there are other items within our financial statements that require estimation, but are not deemed critical as defined above.
We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of the consolidated financial statements.
Revenue Recognition
Our revenue is generated primarily from the sale of products and services. Product revenue consists of sales of arrays, reagents, flow cells, instrumentation and oligos. 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 is recognized in the period during which the related costs are incurred.
We recognize revenue in accordance with the guidelines established by SEC Staff Accounting Bulletin (SAB) No. 104. Under SAB No. 104, revenue cannot be recorded until all of the following criteria have been met: 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. All revenue is recorded net of any applicable allowances for returns or 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 receivables is reasonably assured. Revenue from the sale of instrumentation is recognized when earned, which is generally upon shipment. Revenue for genotyping and sequencing services is recognized when earned, which is generally at the time the genotyping and sequencing analysis data is delivered to the customer.


29


In order to assess whether the price is fixed and determinable, we ensure there are no refund rights. If payment terms are based on future performance or a right of return exists, we defer revenue recognition until the price becomes fixed and 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. Changes in judgments and estimates regarding application of SAB No. 104 might result in a change in the timing or amount of revenue recognized.
Sales of instrumentation generally include a standard one-year warranty. We also sell separately priced maintenance (extended warranty) contracts, which are generally for one or two years, 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 our warrantied products were greater than our estimates, gross margins could be adversely affected.
While the majority of our sales agreements contain standard terms and conditions, we do enter into agreements that contain multiple elements or non-standard terms and conditions. Emerging Issues Task Force (EITF)No. 00-21,Revenue Arrangements with Multiple Deliverables,provides guidance on accounting for arrangements that involve the delivery or performance of multiple products, services, or rights to use assets within contractually binding arrangements. Significant contract interpretation is sometimes required to determine the appropriate accounting, including whether the deliverables specified in a multiple element arrangement should be treated as separate units of accounting for revenue recognition purposes, and if so, how the price should be allocated among the deliverable elements, when to recognize revenue for each element, and the period over which revenue should be recognized. We recognize revenue for delivered elements only when we determine that the fair values of undelivered elements are known and there are no uncertainties regarding customer acceptance.
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 and review historical loss rates. If the financial condition of our customers were to deteriorate, additional allowances could be required.
Inventory Valuation
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 supercede old ones. We regularly review inventory for excess and obsolete products and components, taking into account product life cycle and development plans, product expiration and quality issues, historical experience and our current inventory levels. If actual market conditions are less favorable than anticipated, additional inventory adjustments could be required.
Contingencies
We are subject to legal proceedings primarily related to intellectual property matters. Based on the information available at the balance sheet dates and through consultation with our legal counsel, we assess the likelihood of any adverse judgments or outcomes of these matters, as well as the potential ranges of probable losses. If losses are probable and reasonably estimable, we will record a liability in accordance with Statement of Financial Accounting Standards (SFAS) No. 5,Accounting for Contingencies.

Goodwill and Intangible Asset Valuation
Our goodwill represents the excess of the cost over the fair value of net assets acquired from our Solexa and Cyvera acquisitions. Our intangible assets are comprised primarily of acquired technology and customer relationships from the acquisition of Solexa and licensed technology from the Affymetrix settlement. We make significant judgments in relation to the valuation of goodwill and intangible assets resulting from (i) acquisitions; and (ii) litigation settlements.
In determining the carrying amount of our goodwill and intangible assets arising from acquisitions, we used the purchase method of accounting. The purchase method of accounting requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including in-process research and development (IPR&D). Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to at least annual impairment tests. The amounts and useful lives assigned to other acquired intangible assets impact future amortization, and the amount assigned to IPR&D is expensed immediately.
Determining the fair values and useful lives of intangible assets acquired as part of litigation settlements also requires the exercise of judgment. While there are a number of different generally accepted valuation methods to estimate the value of intangible assets, we used the discounted cash flow method in determining the value of licensed technology associated with the settlement of our Affymetrix litigation. This method required significant management judgment to forecast the future operating results used in the analysis. In addition, other significant estimates were required such as residual growth rates and discount factors. The estimates we used to value and amortize intangible assets were consistent with the plans and estimates that we use to manage our business and based on available historical information and industry estimates and averages. These judgments can significantly affect our net operating results. In addition, we performed a sensitivity analysis to determine the effect a change in revenue projections of 10% would have on our intangible asset, noting the impact would be a reduction or increase in the value of the intangible asset of $2.0 million.
SFAS No. 142,Goodwill and Other Intangible Assets,requires that goodwill and certain intangible assets be assessed for impairment using fair value measurement techniques. If the carrying amount of a reporting unit exceeds its fair value, then a goodwill impairment test is performed to measure the amount of the impairment loss, if any. The goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as in a business combination. Determining the fair value of the implied goodwill is judgmental in nature and often involves the use of significant estimates and assumptions. These estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized and also the magnitude of any such charge. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. These approaches use significant estimates and assumptions, including projection and timing of future cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, determination of appropriate market comparables, and determination of whether a premium or discount should be applied to comparables. It is reasonably possible that the plans and estimates used to value these assets may be incorrect. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges. We have performed our annual test of goodwill as of May 1, 2007, noting no impairment, and have determined there has been no impairment of goodwill through December 30, 2007.
Stock-Based Compensation
We account for stock-based compensation in accordance with SFAS No. 123R,Share-Based Payment.Under the provisions of SFAS No. 123R, stock-based compensation cost is estimated at the grant date based on the award’s fair-value as calculated by the Black-Scholes-Merton (BSM) option-pricing model and is recognized as expense over the requisite service period. The BSM model requires various highly judgmental assumptions including volatility, forfeiture rates, and expected option life. If any of


31


these assumptions used in the BSM model change significantly, stock-based compensation expense may differ materially in the future from that recorded in the current period.
Income Taxes
In accordance with SFAS No. 109,Accounting for 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. 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. As of December 30, 2007, we have maintained a valuation allowance only against certain U.S. and foreign deferred tax assets that we concluded have not met the “more likely than not” threshold required under SFAS No. 109.
Due to the adoption of SFAS No. 123R, we recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, we follow 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 us.
Effective January 1, 2007, we adopted FASB Interpretation (FIN) No. 48,Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in tax positions. FIN No. 48 requires that 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. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense.52 weeks.

Total revenue $666,324  $573,225  $93,099   16%
                 
Product revenue consists primarily of revenue from the sale of consumables and instruments.
Consumable revenue increased $57.6 million, or 17%, to $391.3 million for the year ended January 3, 2010 compared to $333.7 million for the year ended December 28, 2008. Microarray consumable revenue, which constituted more than half of our consumable 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%, driven by growth in the installed base of our Genome Analyzer systems and the progression of customer labs ramping to production scale. The increase was partially offset by a loss of sales related to a quality issue affecting our paired-end cluster kits that arose in September 2009 when some of our larger sequencing customers began experiencing higher than average error rates on the second read of their paired-end analysis. During the fourth quarter, we began shipping reformulated paired-end cluster kits at full capacity and cleared the related shipping backlog.
Revenue 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, 2008 primarily due to a $56.4 million, or 43%, increase in sales of our sequencing systems. During 2009 as compared to 2008 both units sold and average selling prices increased for our Genome Analyzer systems, which constitute a majority of sequencing instrument revenue. The increase in units sold was driven by increased demand for next generation sequencing and oursequencing-by-synthesis technology. The increase 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 was partially offset by a $16.4 million, or 30%, decrease in the sales of our microarray systems, which declined primarily due to customers delaying the start of new GWAS 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 and the benefit of decreased costs associated with the reformulation of our sequencing kits launched at the end of the third quarter of 2008. The cost of sequencing instruments decreased as a percentage of related revenue due to production efficiencies and reduced material costs coupled with higher average selling prices.

Total operating expenses $316,953  $247,977  $68,976   28%
                 
The increase in research and development was driven primarily by a $22.9 million increase in personnel-related expenses, including salaries, non-cash stock-based compensation and benefits, a $10.4 million increase to non-personnel related expenses and an increase in outside services of $3.2 million attributable to consulting fees. These increases are primarily related to the growth in our efforts to optimize and commercialize our sequencing and BeadArray technologies.
The increase in selling, general and administrative expenses was driven by an increase of $26.6 million in personnel-related expenses associated with the growth of our business, including salaries, non-cash stock-based compensation and benefits.

Interest income decreased despite an increase in our average cash and investment balance due to an overall decline in interest rates during 2009. Interest expense increased due to the amortization of the discount on our convertible senior notes. Other income, net decreased due to a decrease of $1.5 million in gains on net foreign currency transactions, which was partially offset by a gain of $0.8 million on the conversion of a portion of our debt during the first quarter of 2009.

Provision for income taxes $41,844  $33,271  $8,573   26%
The increase in the provision for income taxes was attributable to the increase in the consolidated income before income taxes. The effective tax rate decreased 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.
Comparison of Years Ended December 28, 2008 and December 30, 2007
Our 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 years ended December 28, 2008 and December 30, 2007 were both 52 weeks.

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 consumables was primarily attributable to the growth of our installed base of instruments and the progression of customer labs ramping to production scale.
Revenue 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 product and service and other revenue $205,624  $132,436  $73,188   55%
                 
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 increase in research and development was driven by a $17.4 million increase in personnel-related expenses associated with increased headcount, including salaries, non-cash stock-based compensation and benefits, an $11.6 million increase to non-personnel related expenses associated with the growth of our business and a $1.5 million increase to accrued compensation expense associated with contingent consideration for the Avantome acquisition completed on August 1, 2008. These increases were partially offset by a decrease in outside services of $4.5 million primarily related to a decrease in consulting fees.
The increase in selling, general and administrative expenses was driven primarily by an increase of $42.8 million in personnel-related expenses, including salaries, non-cash stock-based compensation and benefits and a $4.0 million increase to non-personnel related expenses.

Interest income decreased due to a change in our cash and investment portfolio to a mix of shorter duration maturities and an increased number of agency-rated investments coupled with the overall decline in interest rates due to market conditions. Interest expense increased due to the amortization of the discount on our convertible senior notes and an additional month and a half of interest expense recorded in the year ended December 28, 2008 compared to the year ended December 30, 2007. Other income (expense), net increased primarily due to $1.9 million in net foreign currency transaction gains for the year ended December 28, 2008 compared to immaterial losses recorded in the year ended December 30, 2007.

Operating Activities
Cash provided by operating activities for the year ended January 3, 2010 consists of net income of $72.3 million plus net non-cash adjustments of $113.5 million and an $11.3 million increase in net operating assets. The primary non-cash expenses added back to net income included share based compensation of $60.8 million and depreciation and amortization expense related to property and equipment, intangibles and the debt discount on our convertible notes totaling $51.5 million. The main drivers 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.


38


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 primary source of our liquidity. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing and financing needs. Historically, we have issued debt and equity securities to finance our requirements to the extent that cash provided by operating activities was not sufficient to fund our needs. We may require additional funding 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-term investments include marketable securities and auction rate securities totaling $494.0 million and $54.9 million, respectively. Our marketable securities consist of debt securities in government sponsored entities, corporate debt securities and U.S treasury notes. We do not hold securities backed by mortgages. Our auction rate securities were issued primarily by municipalities and universities. The markets for auction rate securities effectively ceased when the vast majority 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 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. See Note 7 of Notes to Consolidated Financial Statements for further discussion of the terms of the convertible senior notes.
Our primary short-term needs for capital, which are subject to change, include expenditures related to:
• 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;
• the continued advancement of research and development efforts;
• the acquisition of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities;


39


• improvements in our manufacturing capacity and efficiency; and
• the expansion needs of our facilities, including costs of leasing additional facilities.
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 operations will be sufficient to fund our operating needs in 2010, barring unforeseen circumstances. 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.
Off-Balance Sheet Arrangements
We do not participate in any transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. During the fiscal year ended January 3, 2010, we were not involved in any “off balance sheet arrangements” within the meaning of the rules of the Securities and Exchange Commission.
Contractual Obligations
Contractual obligations represent future cash commitments and liabilities under agreements with third parties, and exclude orders for goods and services entered into in the normal course of business that are not enforceable or legally binding.

(2)Debt obligations include the principal amount of our convertible senior notes and interest payments totaling 0.625% per annum. Although these notes mature in 2014, we classify the notes as current liabilities because the conditions to convertibility were satisfied during the last three fiscal quarters of

2009 and may be satisfied during certain quarters in 2010. See Note 7 of Notes to Consolidated Financial Statements for further discussion of the terms of the convertible senior notes.
(3)The $10.0 million included within contingent consideration is the amount owed to the former shareholders of Avantome, Inc. for the achievement of a certain date-specific milestones. The table excludes $20.0 million in additional contingent cash consideration we may be required to pay based on the achievement of certain additional milestones that do not have a fixed funding date and are subject to certain conditions that may or may not occur.

Total revenue for the years ended December 30, 2007 and December 31, 2006 was $366.8 million and $184.6 million, respectively. This represents an increase of $182.2 million for 2007, or 99%, compared to 2006.
 
Product revenue consists primarily of revenue from the sale of consumables and instruments.
Consumable revenue increased $57.6 million, or 17%, to $326.7$391.3 million for the year ended January 3, 2010 compared to $333.7 million for the year ended December 30, 200728, 2008. Microarray consumable revenue, which constituted more than half of our consumable 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 $155.8the 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%, driven by growth in the installed base of our Genome Analyzer systems and the progression of customer labs ramping to production scale. The increase was partially offset by a loss of sales related to a quality issue affecting our paired-end cluster kits that arose in September 2009 when some of our larger sequencing customers began experiencing higher than average error rates on the second read of their paired-end analysis. During the fourth quarter, we began shipping reformulated paired-end cluster kits at full capacity and cleared the related shipping backlog.
Revenue 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 31, 2006. Consumable products and instruments

During 2009 as compared to 64%2008 both units sold and 28%average selling prices increased for our Genome Analyzer systems, which constitute a majority of sequencing instrument revenue. The increase in units sold was driven by increased demand for next generation sequencing and oursequencing-by-synthesis technology. The increase in average selling prices was attributable to the year ended December 31, 2006, respectively. The change in sales associated with our product mix is due to increased sales in instruments primarily attributabletransition from the Genome Analyzer I to the Genome Analyzer which was introduced duringII in the firstsecond quarter of 2007. Growth in consumable revenue was primarily attributable to strong demand for our Infinium products. We expect to see continued growth in product revenue, which can be mainly attributed2008 and technological improvements leading to the launch of several new products, salesthe Genome Analyzer IIx in the second quarter of existing products and the growth of our installed base of instruments.
Service and other revenue increased to $40.1 million for the year ended December 30, 2007 from $28.8 million for the year ended December 31, 2006. Service and other revenue includes revenue generated from genotyping and sequencing service contracts and extended warranty contracts. In 2007, service and other revenue also includes research revenue. Historically, research revenue was included in a separate line item on the Consolidated Statements of Operations.2009. The increase in service and othersequencing instrument revenue iswas partially offset by a $16.4 million, or 30%, decrease in the sales of our microarray systems, which declined primarily due to customers delaying the completionstart of several significant Infiniumnew GWAS in anticipation of new and iSelect custom SNP genotyping service contractsrare variant content from the 1000 Genomes Project, order delays directly related to stimulus funding under the Recovery Act and sequencing services contracts. We expect sales from SNP genotyping and sequencing services contracts to fluctuate onthe impact of reduced foundation funding at a yearly and quarterly basis, depending on the mix and number of contracts that are completed. The timing of completion of SNP genotyping and sequencing services contracts are highly dependent on the customers’ schedules for delivering the SNPs and samples to us.few key customers.

During the year ended December 30, 2007,28, 2008, we recorded $303.4 million of acquired IPR&D resulting fromcharges of $24.7 million as a result of the Solexa acquisition. At theAvantome, Inc. acquisition date, Solexa’s ongoing research and development initiatives were primarily involved with the development of its genetic analysis platform for sequencing and expression profiling. These in-process research and development projects are comprised of Solexa’s reversible terminating nucleotide biochemistry platform, referred to assequencing-by-synthesis (SBS) biochemistry, as well as Solexa’s reagent, analyzer and sequencing services related technologies, which were valued at $237.2 million, $44.2 million, $19.1 million and $2.9 million, respectively, at the acquisition date. Although these projects were approximately 95% complete at the acquisition date, they had not reached technological feasibility and had no alternative future use. Accordingly, the amounts allocated to those projects were written off in the first quarter of 2007, the period the acquisition was consummated. Acquisitions of businesses, products or technologies by us in the future may result in substantial charges for acquired IPR&D that may cause fluctuations in our interim or annual operating results. There were no charges resulting from any acquisitions during the same period in fiscal 2006.

Provision (benefit) for income taxes $(10,426) $2,652   (493%)
The provision (benefit) for income taxes was approximately ($10.4) million and $2.7 million for the years ended December 30, 2007 and December 31, 2006, respectively. The provision consists of federal, state, and foreign income tax expense, offset in 2007 by the release of the valuation allowance against a significant portion of our U.S. deferred tax assets.
During the year ended December 30, 2007, we utilized approximately $72.9 million and $10.8 million of our federal and state net operating loss carryforwards, respectively, to reduce our federal and state income taxes. As of December 30, 2007, we had net operating loss carryforwards for federal and state tax purposes of approximately $28.7 million and $99.1 million, respectively, which begin to expire in 2025 and 2015, respectively, unless previously utilized. In addition, we also had U.S. federal and state research and development tax credit carryforwards of approximately $9.2 million and $9.3 million respectively, which begin to expire in 2018 and 2019 respectively, unless previously utilized.
Pursuant to Section 382 and 383 of the Internal Revenue Code, utilization of our net operating losses and credits may be subject to annual limitations in the event of any significant future changes in our


37


ownership structure. These annual limitations may result in the expiration of net operating losses and credits prior to utilization. Previous limitations due to Section 382 and 383 have been reflected in the deferred tax assets as of December 30, 2007.
As of December 30, 2007, we concluded that it is more likely than not that a significant portion of our deferred tax assets will be realized and, accordingly we released a portion of our valuation allowance, approximately $17.1 million of which was recorded as a reduction to the tax provision. In addition, we established current and long term deferred tax assets on the Consolidated Balance Sheets of approximately $26.8 million and $80.1 million, respectively, and decreased the goodwill balances recorded in conjunction with the CyVera and Solexa acquisitions by approximately $2.1 million and $18.4 million, respectively. Based upon the available evidence as of December 30, 2007, we are not able to conclude it is more likely than not certain U.S. and foreign deferred tax assets will be realized. Therefore, we have recorded a valuation allowance of approximately $2.9 million and $25.4 million against certain U.S. and foreign deferred tax assets, respectively.

Total revenue for the years ended December 31, 2006 and January 1, 2006 was $184.6 million and $73.5 million, respectively. This represents an increase of $111.1 million for 2006, or 151%, compared to 2005.
Product revenue increased to $155.8 million for the year ended December 31, 2006 from $57.8 million for the year ended January 1, 2006. The increase in 2006 resulted primarily from higher consumable and BeadStation sales. Growth in consumable revenue was primarily attributable to the launch and shipment of our whole genome genotyping products, the HumanHap300 and HumanHap550 BeadChips. In addition, growth in consumable revenue can be attributed to the growth in our installed base of BeadArray Readers, which has nearly doubled since January 1, 2006. Consumable products constituted 66% of product revenue for year ended December 31, 2006, compared to 47% in the year ended January 1, 2006. We expect to see continued growth in product revenue, which can be partially attributed to the launch of several new products, as well as the growth of our installed base of instruments.
Service and other revenue increased to $28.8 million for the year ended December 31, 2006 from $15.7 million for the year ended January 1, 2006. The increase in service and other revenue is primarily due to the completion of several significant Infinium and GoldenGate SNP genotyping service contracts. We introduced our Infinium services in early 2006. We expect sales from SNP genotyping services contracts to fluctuate on a yearly and quarterly basis, depending on the mix and number of contracts that are completed. The timing of completion of a SNP genotyping services contract is highly dependent on the customer’s schedule for delivering the SNPs and samples to us. This increase in service revenue was partially offset by a decrease in government grants and other research funding of $0.5 million over the prior year due primarily to the completion of several projects funded by grants from the National


38


Institutes of Health. We do not expect research revenue to be a material component of our revenue going forward.

Total cost of product and service and other revenue $59,344  $23,181   156%
             
Cost of product and service and other revenue represents manufacturing costs incurred in the production process, including component materials, assembly labor and overhead, installation, warranty, packaging and delivery costs, as well as costs associated with performing genotyping services on behalf of our customers. Costs related to research revenue are included in research and development expense. Cost of product revenue increased to $51.3 million for the year ended December 31, 2006, compared to $19.9 million for the year ended January 1, 2006, primarily driven by higher consumable and instrument sales. Cost of product revenue for the year ended December 31, 2006 included stock-based compensation expenses resulting from the adoption of SFAS No. 123R totaling $1.3 million. Gross margin on product revenue increased to 67.1% for the year ended December 31, 2006, compared to 65.5% for the year ended January 1, 2006. The increase in gross margin percentage is primarily due to the impact of favorable product mix, as well as decreased manufacturing costs. A higher percentage of our revenue in 2006 was generated from the sale of consumables, which generally have a more favorable gross margin than other products. The decrease in manufacturing costs is primarily due to reduced raw material costs as a result of more favorable negotiated contracts with our vendors and improvements in our manufacturing processes. This increase in gross margin was offset, in part, by the impact of stock-based compensation charges, which decreased our gross margin by 83 basis points in 2006 compared to 2005.
Cost of service and other revenue increased to $8.1 million for the year ended December 31, 2006, compared to $3.3 million for the year ended January 1, 2006, primarily due to higher service revenue. Cost of service and other revenue for the year ended December 31, 2006 included stock-based compensation expenses resulting from the adoption of SFAS No. 123R totaling $0.2 million. Gross margin on service and other revenue decreased to 71.9% for the year ended December 31, 2006, compared to 79.3% for the year ended January 1, 2006. The decrease is due primarily to a change in the mix of projects, as well as the impact of stock-based compensation charges, the latter having decreased our service and other revenue gross margin by 85 basis points in 2006 compared to 2005.
We expect product mix to continue to affect our future gross margins. However, we expect our market to become increasingly price competitive and our margins may fluctuate from year to year and quarter to quarter.

Exclusive of these stock-based compensation charges, the increase in research and development expenses for the year ended December 31, 2006 is primarily due to the development of our recently-acquired VeraCode technology purchased in conjunction with our acquisition of CyVera in April 2005. We launched the first products resulting from this acquisition during the first quarter of 2007. Research and development expenses related to the VeraCode technology increased $2.7 million for the year ended December 31, 2006, compared to the year ended January 1, 2006. In addition, costs to support our Oligator technology platform and BeadArray research activities decreased $1.0 million for the year ended December 31, 2006, compared to the year ended January 1, 2006.
We believe a substantial investment in research and development is essential to remaining competitive and expanding into additional markets.

Sales and marketing expenses increased $10.6 million during the year ended December 31, 2006, compared to the year ended January 1, 2006. The increase is primarily due to increases of $6.5 million attributable to personnel-related expenses, $3.2 million of stock-based compensation expense and $0.9 million attributable to other non-personnel-related costs, mainly sales and marketing activities for our existing and new products. General and administrative expenses increased $15.3 million during the year ended December 31, 2006, compared to the year ended January 1, 2006, due to increases of $5.5 million of stock-based compensation expense, $5.3 million in outside legal costs related to the Affymetrix litigation, $3.1 million in personnel-related expenses associated with the growth of our business and $1.4 million in outside consulting costs.

Provision for income taxes $41,844  $33,271  $8,573   26%
 
The increase in the provision for income taxes was attributable to the increase in the consolidated income before income taxes. The effective tax rate decreased 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 $2.779% 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 consumables was primarily attributable to the growth of our installed base of instruments and the progression of customer labs ramping to production scale.
Revenue 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 product and service and other revenue $205,624  $132,436  $73,188   55%
                 
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.

These increases were partially offset by a decrease in outside services of $4.5 million primarily related to a decrease in consulting fees.
The increase in selling, general and administrative expenses was driven primarily by an increase of $42.8 million in 2006, up from $0.2personnel-related expenses, including salaries, non-cash stock-based compensation and benefits and a $4.0 million increase to non-personnel related expenses.

Previous limitations due to Section 382 and 383 have been reflected in the deferred tax assets as of December 31, 2006.
Based upon the available evidence as of December 31, 2006, we are not able to conclude it is more likely than not the remaining deferred tax assets in the U.S. will be realized. Therefore, we have recorded a full valuation allowance against thea significant portion of our U.S. deferred tax assets of approximately $36.5 million.assets.

Historically, our sources of cash have included:Operating Activities
 
• issuance of equity and debt securities, including cash generated from the exercise of stock options and participation in our Employee Stock Purchase Plan (ESPP);
• cash generated from operations, primarily from the collection of accounts receivable resulting from product sales; and
• interest income.
Cash provided by operating activities for the year ended January 3, 2010 consists of net income of $72.3 million plus net non-cash adjustments of $113.5 million and an $11.3 million increase in net operating assets. The primary non-cash expenses added back to net income included share based compensation of $60.8 million and depreciation and amortization expense related to property and equipment, intangibles and the debt discount on our convertible notes totaling $51.5 million. The main drivers 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.
 
Our historical cash outflows have primarily been associated with:Investing Activities
 
• cash used for operating activities such as the purchase and growth of inventory, expansion of our sales and marketing and research and development infrastructure and other working capital needs;
• cash used for our stock repurchases;
• expenditures related to increasing our manufacturing capacity and improving our manufacturing efficiency; and
• interest payments on our debt obligations.
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.
 
Other factors that impactIn August 2008, we completed our acquisition of Avantome, Inc. As consideration for the acquisition, we paid $25.8 million in cash, inflowincluding transaction costs, at the closing of the acquisition, and outflow include:
• significant increases in our product and services revenue, leading to gross margins greater than 63% in each of the last three fiscal years. As our product sales have increased significantly since 2001, our gross profit and operating income have increased significantly as well, providing us with an increased source of cash to finance the expansion of our operations; and
• fluctuations in our working capital.
As of December 30, 2007, we had cash, cash equivalents and short-term investments of $386.1 million, compared to $130.8have subsequently paid $15.0 million as of December 31, 2006.February 1, 2010 based on the achievement of, or amendments relating to, certain milestones. We currently investmay 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 funds in U.S. dollar-based short maturity mutual funds, commercial paper, corporate bonds, treasury notes, auction rate securities and municipal bonds. We do not hold securities backed by mortgages. As of December 30, 2007, our short-term investments included $14.7Affymetrix settlement, we recorded a $36.0 million of high-grade (AAA rated) auction rate securities issued primarily by municipalities and universities.

Financing Activities
Cash used in financing activities totaled $98.9 million for the year ended December 30, 2007 were attributable toJanuary 3, 2010. During the purchase of available-for-sale securities foryear we repurchased approximately $598.4 million, the repurchase of an aggregate of 7.46.1 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 $251.63.1 million as well as approximately $139.0 millionshares of our common stock for the purchase of a convertible note hedge. These convertible note transactions and our stock repurchase program are discussed in detail below.$70.8 million.
 
OnIn February 16, 2007, we issued $400.0 million principal amount of 0.625% Convertible Senior Notesconvertible senior notes due 2014 (the Notes).2014. The net proceeds from the offering, after deducting the initial purchasers’ discount and offering expenses, were approximately $390.3 million. We used approximately $201.6 million of the net proceeds to purchase approximately 5.811.6 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 are usingmanage our business to maximize operating cash flows as the primary source of our liquidity. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing and financing needs. Historically, we have issued debt and equity securities to finance our requirements to the extent that cash provided by operating activities was not sufficient to fund our needs. We may require additional funding 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-term investments include marketable securities and auction rate securities totaling $494.0 million and $54.9 million, respectively. Our marketable securities consist of debt securities in government sponsored entities, corporate debt securities and U.S treasury notes. We do not hold securities backed by mortgages. Our auction rate securities were issued primarily by municipalities and universities. The markets for auction rate securities effectively ceased when the vast majority 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 the net proceedsNotes to Consolidated Financial Statements for other general corporate purposes, which may include acquisitionsfurther information regarding our auction rate securities.
Our outstanding convertible senior notes were convertible into cash and, additional repurchasesif applicable, shares of our common stock. The notes mature on February 15, 2014 and bear interest semi-annually at a rate of 0.625% per year, payable on February 15 and August 15 of each year, beginning on August 15, 2007. In addition, we may in certain circumstances be obligated to pay additional interest. If a “designated event,” as defined in the indenturestock for the period from April 1, 2008 through December 31, 2008 and became convertible again beginning April 1, 2009 through December 31, 2009.

On February 4, 2009, the settlement date, we paid the noteholder the conversion value of the notes may require us to repurchase all or a portion of their notes forin cash, at a repurchase price equalup to the principal amount of the notes to be repurchased, plus accrued and unpaid interest. In addition,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 we must paywas offset by the principal portion in cash. The notes will become convertible only in certain circumstances based on conditions relating to the trading pricereacquisition of the notes and our common stock or uponshares under the occurrenceconvertible note hedge transactions entered into in connection with the offering of specified corporate events, and we expect the notesnotes. See Note 7 of Notes to becomeConsolidated Financial Statements for further discussion of the terms of the convertible beginning in the second quarter of 2008 if the trading price of our common stock does not decline from current levels. The notes also will, by their terms, become convertible at any time from, and including, November 15, 2013 through the third scheduled trading day immediately preceding February 15, 2014.
On February 20, 2007, we executed aRule 10b5-1 trading plan to repurchase up to $75.0 million of our outstanding common stock over a period of six months. We repurchased approximately 1.6 million shares of our common stock under this plan for approximately $50.0 million in cash. As of December 30, 2007, this plan had expired.senior notes.
 
Our primary short-term needs for capital, which are subject to change, include expenditures related to:
 
 • the $90.0 million liability recorded at December 30, 2007 for the one-time payment made to Affymetrix on January 25, 2008, in accordance with the settlement agreement entered on January 9, 2008;
• our facilities expansion needs, including costs of leasing additional facilities;
• the acquisition of equipmentpotential strategic acquisitions and other fixed assets for use in our current and future manufacturing and research and development facilities;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;
 
 • the continued advancement of research and development efforts; and
 
• the acquisition of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities;


39


 • improvements in our manufacturing capacity and efficiency.efficiency; and
• the expansion needs of our facilities, including costs of leasing additional facilities.
 
Approximately $24.3 million of our net cash generated from operations for the year ended December 30, 2007 was used on capital expenditures, primarily for manufacturing and research and development equipment, furniture, fixtures and computer equipment. 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.


43


We anticipate that our current cash and cash equivalents and income from operations will be sufficient to fund our operating needs for at least the next 12 months.in 2010, barring unforeseen circumstances. 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. Due to expansion of our facilities and manufacturing operations, we anticipate spending approximately $25.0 million in capital expenditures during 2008. Our future capital requirements and the adequacy of our available funds will depend on many factors, including:
 
 • our ability to successfully commercialize our sequencing and VeraCodefurther develop our technologies and to expandcreate innovative products in our SNP genotyping and sequencing services product lines;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.
 
As a result of the factors listed above, we may require additional funding in the future. Our failure to raise capital on acceptable terms, when needed, could have a material adverse effect on our business.

We do not participate in any transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, (SPEs), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. During the fiscal year ended December 30, 2007,January 3, 2010, we were not involved in any “off balance sheet arrangements” within the meaning of the rules of the Securities and Exchange Commission.
 
Contractual Obligations
 
Contractual obligations represent future cash commitments and liabilities under agreements with third parties, and exclude orders for goods and services entered into in the normal course of business that are not enforceable or legally binding and contingent liabilities for which we cannot reasonably predict future payment. Additionally, the table excludes uncertain tax positions of $21.4 million. The expected timing of payment of the obligations presented below is estimated based on current information. Timing of payments and actual amounts paid may be different depending on changes toagreed-upon terms or amounts for some obligations.

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 1 of the Consolidated Financial Statements.
Revenue Recognition
Our 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 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 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 delivered to the customer or agreed-to milestones are reached.
In order to assess whether the price is fixed or determinable, we ensure there are no refund rights. If 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, 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, 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 is 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 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, 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.
Investments
We determine the fair value of our 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


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 discussionidentical 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 our operating leases.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 may 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 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 that our reserves will continue to be adequate.
Inventory Valuation
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 and quality issues, historical experience and our current inventory levels. If actual market conditions are less favorable than anticipated, additional inventory adjustments could be required.
Contingencies
We are subject to legal proceedings primarily related to intellectual property matters. We routinely assess the likelihood of adverse judgments or outcomes to these matters, as well as ranges of probable losses, to the extent losses are reasonably estimable. If losses are probable and reasonably estimable, we will record a liability and an expense for the estimated loss. Disclosure for specific legal contingencies is provided if the likelihood of occurrence is probable and the exposure is considered material to the consolidated financial statements. In making determinations of likely outcomes of litigation matters, management considers many factors. These factors 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, which may result in the recording of an accrual or a change in a previously recorded accrual. Predicting the outcome 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.
Business Combinations and Intangible Asset Valuation
Under the purchase method of accounting, we allocate the purchase price of acquired companies to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. We record the excess of purchase price over the aggregate fair values 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 primarily of licensed technology from the Affymetrix settlement entered into on January 9, 2008 and acquired core technology and customer relationships from the Solexa acquisition. Management uses a discounted cash flow method to value our 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 estimate the fair value of intangible assets and other long-lived assets that have finite useful lives whenever an event or change in circumstances indicates that the carrying value of the asset may not be recovered through undiscounted future operating cash flows. We test for potential impairment of goodwill annually in our second fiscal quarter or whenever indicators of impairment arise.
In order to estimate the fair value of purchased 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. 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. Impairment charges could materially decrease our future net income and result in lower asset values on our balance sheet.

Convertible Senior Notes
(3)“Other” in the above table includes amounts owed as a result of our litigation settlements occurring subsequent to December 30, 2007. See Note 8 of Notes to Consolidated Financial Statements for further discussion of the related settlement.
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 directors 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-based awards using the BSM model requires the use of certain estimates and highly judgmental assumptions that affect the amount of stock-based compensation expense recognized in our Consolidated Statements of Operations. These include estimates of the expected volatility of our stock price, expected option life, 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, 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. 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. If any of the assumptions used in the BSM model change significantly, stock-based compensation expense may differ materially from what we have recorded in the current period.
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. 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, 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, 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 million and $12.1 million against certain U.S. and foreign deferred tax assets, respectively.
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.

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk.
 
Interest Rate Sensitivity
 
Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. 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, if a 100 basis point change in overall interest rates were to occur in 2010, our interest income would change by approximately $6.9 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.
 
Market Price Sensitive Instruments
 
In order to reduce the potential equity dilution, in connection with the issuance (and potential conversion) of our convertible notes, we entered into a convertible note hedge contracttransactions, entitling us to purchase a maximum of 11,451,480up to 18,322,320 shares of our common stock (subject to adjustment) at an initiala strike price of $43.66$21.83 per share, (subjectsubject to adjustment). Upon conversionadjustment. In addition, we sold to the hedge transaction counterparties warrants exercisable on a net-share basis, for up to 18,322,320 shares of our Convertible Senior Notes, this hedge contract is expected to reduce the equity dilution if the daily volume-weighted averagecommon 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 commonscommon stock exceeds the strike price of the hedge. We also entered into warrant transactions withwarrants on the counterparties of the convertible note hedge transactions entitling them to acquire a maximum of 18,322,320 shares of our common stock (subject to adjustment) at an initial strike price of $62.87 per share (subject to adjustment).

We did not hold any material derivative financial instruments for the year ended December 31, 2006.warrants are exercised.
 
Foreign Currency Exchange Risk
 
Although mostMany of our revenue isreporting entities conduct a portion of their business in currencies other than the entity’s U.S. dollar functional currency. These transactions give rise to monetary assets and liabilities that are denominated in currencies other than the entity’s functional currency. 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. Both realized and unrealized gains or losses on the value of these monetary assets and liabilities are included in U.S. dollars, some portionsthe determination of our revenuenet income (loss). We recognized a

Item 9.  Changes In and Disagreements with Accountants on Accounting and Financial Disclosure.
 
None.
 
Item 9A.  Controls and Procedures.
 
We design our internal controls to provide reasonable assurance that (1) our transactions are properly authorized; (2) our assets are safeguarded against unauthorized or improper use; and (3) our transactions are properly recorded and reported in conformity with U.S. generally accepted accounting principles. We also maintain internal controls and procedures to ensure that we comply with applicable laws and our established financial policies.
 
We have carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined inRules 13a-15(e) and15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Securities Exchange Act), as of December 30, 2007.January 3, 2010. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of December 30, 2007,January 3, 2010, our disclosure controls and procedures were effective to ensure that (a) the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (b) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management have concluded that the disclosure controls and procedures are effective at the reasonable assurance level. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.
 
An evaluation was also performed under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of any change in our internal control over financial reporting that occurred during the fourth quarter of 20072009 and that has materially affected, or is


47


reasonably likely to materially affect, our internal control over financial reporting. Other than completing the integration of Solexa, Inc.’s internal controls over financial reporting into our financial reporting systems during the fourth quarter of 2007, thatThe evaluation did not identify any such change.
 
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 December 30, 2007.January 3, 2010. The effectiveness of our internal control over financial reporting as of December 30, 2007January 3, 2010 has been audited by Ernst & Young LLP, an independent registered accounting firm, as stated in their report which is included herein.

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 December 30, 2007,January 3, 2010, 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 December 30, 2007,January 3, 2010, 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, 2007January 3, 2010 and December 31, 2006,28, 2008, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 30, 2007January 3, 2010 of Illumina, Inc. and our report dated February 22, 200826, 2010 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 December 30, 2007January 3, 2010 and December 31, 2006,28, 2008, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 30, 2007.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 December 30, 2007January 3, 2010 and December 31, 2006,28, 2008, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 30, 2007,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 Januaryas of December 29, 2008 and retroactively adjusted all periods presented in the consolidated financial statements for this change. Also described in Note 1 2006, Illumina, Inc. changedis the Company’s 2009 change in its method of accounting for share-based payments in accordancerevenue recognition with Statementthe adoption of amendments to the Financial Accounting Standards Board Accounting Standards Codification resulting from Accounting Standards Update No. 123R, Share-Based Payment.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 December 30, 2007,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 22, 200826, 2010 expressed an unqualified opinion thereon.

Both guarantees were released during 2007.
 
Fair Value of Financial Instruments
 
The carrying amounts of certainfinancial 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 financial instruments, including cashconvertible notes was $390.0 million and cash equivalents, accounts$553.2 million, respectively, at January 3, 2010 and notes receivable, accounts payable, accrued liabilities,$400.0 million and convertible senior notes approximate fair value.$473.0 million, respectively, at December 28, 2008.

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 the cost over the fair value of net assets acquired. SFAS No. 142,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, requiresother intangible assets that goodwill be testedhave indefinite useful lives are reviewed for impairment at least annually for impairmentduring the second fiscal quarter, or more frequently if events and circumstances warrant,an event occurs indicating the potential for impairment.

Reserve for Product Warranties
 
The Company generally provides a one-year warranty on instrumentation.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 associated with system sales.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.

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 instrumentation, and oligonucleotides (oligos), which are short sequences of DNA.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 isare 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 applicable allowances for returns or 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 receivablesreceivable is reasonably assured. Revenue from the sale of instrumentation is recognized when earned, which is generally upon shipment. Revenue for genotyping and sequencing services is recognized when earned, which is generally at the time the genotyping andor sequencing analysis data is deliveredmade available to the customer.customer or agreed upon milestones are reached.
 
In order to assess whether the price is fixed andor 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 andor 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 or two years,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 warrantied products under warranty were greater than its estimates, gross margins could be adversely affected.
 
WhileThe 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 majority of its sales agreements contain standard terms and conditions, the Company does enter into agreements that contain multiple elements or non-standard terms and conditions.

The relative selling price for each deliverable is generallydetermined using vendor specific objective evidence (VSOE) of selling price or third-party evidence of selling price if VSOE does not exist.

evidence of fair value existed for the undelivered items but not for the delivered items, the residual method iswas used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equalsequaled the total arrangement consideration less the aggregate fair value of the undelivered items. When the Company iswas unable to establish stand-alone value for delivered items or when fair value of undelivered items hashad not been established, revenue iswas deferred until all elements arewere delivered and services havehad been performed, or until fair value cancould 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 that the fair values of undelivered elements are known and 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.
• 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 following table presents the Company’s fair value hierarchy for assets measured at fair value on a recurring basis as of January 3, 2010 (in thousands):

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
 
In accordance with SFAS No. 109,Accounting for Income Taxes, theThe 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 thea deferred tax assetsasset will not be achieved.

ForeignFunctional Currency Translation
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.

Stock-Based Compensation
Prior to the beginning of fiscal 2006, the Company measured compensation expense for its employee stock-based compensation plans using the intrinsic value method prescribed by APB Opinion No. 25. The Company applied the disclosure provisions of SFAS No. 123, as amended by SFAS No. 148,Accounting for Stock-Based Compensation — Transition and Disclosure, as if the fair-value-based method had been applied in measuring stock-based compensation expense. Under APB Opinion No. 25, when the exercise price of the Company’s employee stock options was not less than the market price of the underlying stock on the date of the grant, no compensation expense was recognized.
Effective January 2, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R,Share-Based Payment, using the modified prospective transition method. The modified prospective transition method requires that stock-based compensation expense be recorded for all new and unvested stock options, restricted stock and employee stock purchase plan (ESPP) shares that are ultimately expected to vest as the requisite service is rendered. As of December 30, 2007, approximately $122.9 million of total unrecognized compensation cost related to stock options, restricted stock and ESPP shares issued to date is expected to be recognized over a weighted-average period of approximately two years.

This model incorporates various assumptions including expected volatility, expected option life, expected dividends, and the risk-free interest rates. Historically, theThe Company used an expected stock-pricedetermines volatility assumption that was primarily based on historical realized volatility of the underlying stock during a period of time. Beginning the third quarter of 2007, volatility was determined 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.

Net Income ( Loss) per Share
 
Basic and diluted net income (loss) per common share is presented in conformity with SFAS No. 128,Earnings per Share,for all periods presented. In accordance with SFAS No. 128, basic net income (loss)or loss per share is computed usingby dividing net income or loss by the weighted-average number of shares of common stockshares outstanding during the period, less shares subject to repurchase.reporting period. Diluted net income (loss) per share is typically computed usingby dividing net income by the weighted average number of common andshares outstanding during the reporting period increased to include dilutive potential common equivalent shares from stock options 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.

The total number of warrants excluded from the calculation of diluted net loss per share was 1,719,446 for the year ended December 30, 2007. These warrants were assumed as part of the Company’s merger with Solexa, Inc. on January 26, 2007. In addition, the warrants sold to the initial purchasers of the Convertible Senior Notesand/or their affiliates to acquire up to 18,322,320 shares of the Company’s common stock (subject to adjustment) were excluded from the calculation of diluted net income (loss) per share for the year ended December 30, 2007 since the average fair market value of the Company’s stock during the year was below the strike price of $62.87 per share.
Comprehensive Income
 
Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on the Company’savailable-for-sale securities changes in the fair value of derivatives designated as effective cash flow hedges, and foreign currency translation adjustments. The Company has disclosed comprehensive income as a component of stockholders’ equity.

Recent Accounting Pronouncements
 
Adopted Accounting Pronouncements
Convertible Debt Instruments
In September 2006May 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 issued SFAS No. 157,Fair Value Measurements. SFAS No. 157 defines fair value, establishesratified 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 framework for measuring fair value in accordance with GAAP,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 expands disclosures about fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007.settlement provisions. The Company is currently evaluatingadopted this guidance effective December 29, 2008, requiring the impact, if any,Company to perform additional analyses on both its freestanding equity derivatives and embedded equity derivative features. However, the adoption of this pronouncement willguidance did not have a material effect on the Company’s consolidated financial statements.
 
Fair Value of Financial Instruments
In February 2007,April 2009, the FASB issued SFAS No. 159,The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 allows companies to elect to measure certain assets and liabilities at fair value and is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact, if any, the adoption of this pronouncement will haveadditional authoritative guidance on the Company’s consolidated financial statements.
In June 2007, the FASB ratified EITFNo. 07-3,Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities. EITFNo. 07-3 requires that nonrefundable advance payments for goods and services that will be used or rendered in future research and development activities pursuant to executory contractual arrangements be deferred and recognized as an expense in the period that the related goods are delivered or services are performed. EITFNo. 07-3 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact, if any, the adoption of this pronouncement will have on the Company’s consolidated financial statements.
SFAS No. 141(R),Business Combinations, was issued in December of 2007. SFAS No. 141(R) established principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree. SFAS No. 141(R) also provides guidance for recognizing and measuring the goodwill acquired in the business combination and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. The guidance will become effective for fiscal years beginning after December 15, 2008. The Company is currently evaluating the impact, if any, the adoption of this pronouncement will have on the Company’s consolidated financial statements.
2.  Acquisition of Solexa, Inc.
On January 26, 2007, the Company completed its acquisition of Solexa, Inc. (Solexa), a Delaware corporation, in a stock-for-stock merger transaction. The Company issued approximately 13.1 million shares of its common stock as consideration for this merger. The results of Solexa’s operations have been included in the Company’s consolidated financial statements since the acquisition date of January 26, 2007.
Upon the closing of the merger on January 26, 2007, there were approximately 3.7 million shares of the Company’s restricted stock and shares issuable upon the exercise of outstanding options and warrants assumed as part of the acquisition. Total estimated merger consideration also includes approximately $75.3 million, which represents the fair market value of the vested options, warrants and restricted stock assumed. The Company also expects to recognize approximately $14.7 million of non-cash stock-based compensation expense related to unvested stock options and restricted stock at the acquisition date. This expense will be recognized beginning from the acquisition date over a

weighted-average period of approximately two years. These awards were valued using the following assumptions as of January 25, 2007 (the measurement date, as discussed below):
Interest rate4.56 - 5.05%
Volatility54.26%
Expected life0.35 - 3.98 years
Expected dividend yield0%
The purchase price of the acquisition is as follows (in thousands):
     
Fair market value of securities issued $527,067 
Fair market value of change of control bonuses and related taxes  8,182 
Transaction costs not included in Solexa net tangible assets acquired  8,138 
Fair market value of vested stock options, warrants and restricted stock assumed  75,334 
     
Total purchase price $618,721 
     
The fair value of the Company’s shares used in determining the purchase price was based on the average of the closing price of the Company’s common stock for a range of four trading days, comprising of the two days prior to and two days subsequent to January 25, 2007, the measurement date. The measurement date was determined per the guidance in EITFNo. 99-12,Determination of the Measurement Date for the Market Price of Acquirer Securities Issued in a Purchase Business Combination. Based on these closing prices, the Company estimated the fair value of its common stock to be $40.14 per share,financial instruments, which equates to a total fair value of common stock issued of $527.1 million.
Purchase Price Allocation
The Solexa purchase price was allocated to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date (January 26, 2007). The excess of the purchase price over the fair value of net assets acquired was allocated to goodwill.
The Company believes the fair values assigned to the assets acquired and liabilities assumed were based on reasonable assumptions. The following table summarizes the estimated fair values of net assets acquired (in thousands):
     
Current assets $51,444 
Property, plant and equipment, net  6,515 
Other assets  786 
Deferred tax assets  18,360 
Current liabilities  (13,463)

Total net assets acquired $618,721 
     
The Company’s purchase price allocation changed during the fourth quarter of 2007, due to the release of the valuation allowance initially recorded in conjunction with the acquisition of Solexa against

certain deferred tax assets. As a result, the Company decreased the goodwill balance by approximately $18.4 million from the balance as of September 30, 2007 and recorded a deferred tax asset as of December 30, 2007.
In-Process Research and Development
The Company allocated $303.4 million of the purchase price to in-process research and development projects. In-process research and development (IPR&D) represents the valuation of acquired, to-be-completed research projects. At the acquisition date, Solexa’s ongoing research and development initiatives were primarily involved with the development of its genetic analysis platform for sequencing and expression profiling. These in-process research and development projects are composed of Solexa’s reversible terminating nucleotide biochemistry platform, referred to assequencing-by-synthesis (SBS) biochemistry, as well as Solexa’s reagent, analyzer and sequencing services related technologies, which were valued at $237.2 million, $44.2 million, $19.1 million and $2.9 million, respectively, at the acquisition date. Although these projects were approximately 95% complete at the acquisition date, they had not reached technological feasibility and had no alternative future use. Accordingly, the amounts allocated to those projects were written off in the first quarter of 2007, the period the acquisition was consummated.
The values of the research projects were determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting net cash flows from the projects, and discounting the net cash flows to their present value. These cash flows were estimated by forecasting total revenue expected from these products and then deducting appropriate operating expenses, cash flow adjustments and contributory asset returns to establish a forecast of net cash flows arising from the in-process technology. These cash flows were substantially reduced to take into account the time value of money and the risks associated with the inherent difficulties and uncertainties given the projected stage of development of these projects at closing. Due to the nature of the forecast and the risks associated with the projected growth and profitability of the developmental projects, discount rates of 19.5% were considered appropriate for valuation of the IPR&D. The Company believes that these discount rates were commensurate with the projects’ stage of development and the uncertainties in the economic estimates described above.
If these projects are not successfully developed, the sales and profitability of the combined company may be adversely affected in future periods. The Company believes that the foregoing assumptions used in the IPR&D analysis were reasonable at the time of the acquisition. No assurance can be given, however, that the underlying assumptions used to estimate expected project sales, development costs or profitability, or the events associated with such projects, will transpire as estimated.
Identifiable Intangible Assets
Acquired identifiable assets include various patents that are separate and distinct from the intellectual property surrounding the SBS biochemistry platform (core technology) as well as customer relationships. These patents are held in both the United States and Europe. The Company valued the patents and developed technology utilizing a discounted cash flow model which uses forecasts of future royalty savings and expenses related to the intangible assets. The Company utilized a discount rate of 19.5% when preparing this model. The value of the customer relationships is the benefit derived, based upon estimated cash flows, from having a customer in place versus having to incur the time, cost and foregone cash flow required to develop or replace the customer. The amounts assigned to the core technology and customer relationships are $23.5 million and $0.9 million, respectively.

Goodwill
Goodwill represents the excess of the Solexa purchase price over the sum of the amounts assigned to assets acquired less liabilities assumed. The Company believes that the acquisition of Solexa will produce the following significant benefits:provides:
 
 • Increased Market Presencefurther provisions on estimating fair value when the markets become inactive and Opportunities.  The combination of the Company and Solexa should increase the combined Company’s market presence and opportunities for growth in revenue, earnings and stockholder return. The Company believes that the Solexa technology is highly complementary to the Company’s own portfolio of products and services and will enhance the Company’s capabilities to service its existing customers, as well as accelerate the development of additional technologies, products and services. The Company believes that integrating Solexa’s capabilities with the Company’s technologies will better position the Company to address the emerging biomarker research and development and in-vitro and molecular diagnostic markets. The Company began to recognize revenue from products shipped as a result of this acquisition during the first quarter of 2007.quoted prices reflect distressed transactions;

Investment in SolexaAccounting for Subsequent Events
 
On November 12, 2006,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 a definitive securities purchase agreement with Solexa in whichor 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 invested approximately $50recorded 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 Solexa in exchangeNote 1 for 5,154,639 newly issued sharesfurther information on the Company’s revenue recognition policies.
In September 2009, the FASB also ratified authoritative accounting guidance requiring the sales of Solexa common stock in conjunction withall tangible products containing both software and non-software components that function together to deliver the mergerproduct’s essential functionality to be excluded from the scope of the two companies. This investment was valued at $67.8 million assoftware 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 December 31, 2006, which represented a market value of $13.15 per share of Solexa common stock. This investment was eliminated as part ofthis guidance, the Company assessed all software items included in the Company’s purchase accounting uponproduct offerings to be incidental to the closing of the merger on January 26, 2007.product itself and, therefore,

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.

4.5.  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, and 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 associated with system sales.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.

5.7.  Convertible Senior Notes
 
On February 16, 2007, the Company issued $400.0 million principal amount of 0.625% Convertible Senior Notesconvertible senior notes due 2014 (the Notes), which included the exercise of the initial purchasers’ option to purchase up to an additional $50.0 million aggregate principal amount of Notes.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,notes, payable semi-annually in arrears in cash on February 15 and August 15 of each year. The Company made an interest paymentpayments of approximately $1.2 million on February 15, 2009 and August 15, 2007.2009. The Notesnotes mature on February 15, 2014.
 
The Notesnotes will be convertible into cash and, if applicable, shares of the Company’s common stock, $0.01 par value per share, based on an initiala conversion rate, subject to adjustment, of 22.902945.8058 shares per $1,000 principal amount of Notesnotes (which represents an initiala conversion price of approximately $43.66$21.83 per share), only in the following circumstances and to the following extent: (1) during the fivebusiness-day period after any five consecutive tradingtrading-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, after the calendar quarter ending March 31, 2007, 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) the notes will be convertible at any time on or after November 15, 2013 through the third scheduled trading day immediately preceding the maturity date.
In 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 Companynotes.
The hedge transaction entered into convertible note hedge transactions (the hedge) with the initial purchasersand/or their affiliates (the hedge counterparties) entitlingentitles the Company to purchase up to 11,451,48018,322,320 shares of the Company’s common stock subject to adjustment, at an initiala strike price of $43.66approximately $21.83 per share, subject to adjustment.

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.

8.10.  Litigation SettlementsLegal Proceedings
 
In the recent past, the Company incurred substantial costs in defending against patent infringement claimsFrom time to time, we are party to litigation and expects, going forward, to devote substantial financial and managerial resources to protect the Company’s intellectual property and to defend against any future claims asserted against the Company.
Affymetrix Litigation
On January 9, 2008, we resolved all our outstanding litigations with Affymetrix, Inc. (Affymetrix) by entering into a settlement agreement in which we 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 us, and we agreed to dismiss with prejudice our counterclaimsother legal proceedings in the relevant lawsuits. In exchange forordinary course, and incidental to the payment, Affymetrix agreed not to sue us or our affiliates or customers for making, using or selling anyconduct, of our current products, evolutions of those products or services related to those products. In addition, Affymetrix agreed that, for four years, it will not sue us for making, using or selling our products or services that are based on future technology developments. The covenant not to sue covers all fields other than photolithography,business. While the process by which Affymetrix manufactures its arrays and a field in which we do not operate.

The January 2008 settlement resolved complaints Affymetrix had previously filed in the U.S. and abroad. Specifically, on July 26, 2004, Affymetrix had filed a complaint in the U.S. District Court for the District of Delaware alleging that the use, manufacture and sale of our BeadArray products and services, including our Array Matrix and BeadChip products, infringe six Affymetrix patents. At that time Affymetrix was also seeking an injunction against the saleresults of any products that would ultimately be determined to infringe these patents, unspecified monetary damages, interest and attorneys’ fees. Subsequently, on October 24, 2007, Affymetrix had filed complaints inlitigation or other legal proceedings are uncertain, management does not believe the U.S. District Court for the District of Delaware, in Regional Court in Düsseldorf (Germany), and in the High Court of Justice, Chancery Division — Patents Court in London (United Kingdom) alleging that the use, manufacture and sale of certain of our BeadArray products and services, including our Array Matrix and BeadChip products, infringe three U.S. patents and three European patents of Affymetrix. In its U.S. complaint filed in 2007, Affymetrix had also alleged that our sequencing technology, including the Genome Analyzer, infringes two Affymetrix U.S. patents. Affymetrix also sought an injunction against the saleultimate resolution of any products that would ultimately be determinedpending legal matters is likely to infringe these patents, unspecified monetary damages, interest and attorneys’ fees.
Ashave a material adverse effect on our financial position or results of December 30, 2007, the Company accrued for the total $90.0 million payment as a result of the settlement, of which $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 and is included in income (loss) from operations on the Consolidated Statements of Operations. This allocation was determined in accordance with SFAS No. 5,Accounting for Contingencies, andEITF 00-21 using the concepts of fair value based on the 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 Company utilized a discount rate of 9.25% when preparing this model. The effective life and related amortization will be based on the higher of the percentage of usage or the straight-line method. This percentage of usage will be determined using the revenues generated from products covered by the patents previously under dispute. These patents expire at various times through 2015.
Former Employee Claim
On June 15, 2005, a former employee of the Company filed suit against the Company in the U.S. District Court for the District of Delaware seeking an order requiring the Company and the U.S. Patent and Trademark Office to correct the inventorship of certain of the Company’s patents and patent applications by adding the former employee as an inventor, alleging that the Company committed inequitable conduct and fraud in not naming him as an inventor, and seeking a judgment declaring certain of the Company’s patents and patent applications unenforceable, unspecified monetary damages and attorney’s fees. On January 30, 2008, this dispute was resolved to the mutual satisfaction of the parties by entering into a release and settlement agreement pursuant to which all claims pending in that litigation were dismissed with prejudice. As a result of the settlement, the Company recognized a charge of $0.5 million for the year ended December 30, 2007 in income (loss) from operations on the Consolidated Statements of Operations.
Applied Biosystems Litigation
On December 26, 2006, the Applied Biosystems Group of Applera Corporation (Applied Biosystems) filed suit in California Superior Court, Santa Clara County against Solexa (which was acquired by the Company on January 26, 2007). This State Court action is about the ownership of several patents assigned in 1995 to Solexa’s predecessor company (Lynx Therapeutics) by a former employee (Dr. Stephen Macevicz) who is the inventor of these patents and is named as a co-defendant in the suit. Lynx was originally a unit of Applied Biosystems but was spun out in 1992. On May 31, 2007, Applied

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Biosystems filed a second suit, this time against the Company, in the U.S. District Court for the Northern District of California. This second suit seeks a declaratory judgment of non-infringement of the Macevicz patents that are the subject of the State Court action mentioned above. Both suits were later consolidated in the U.S. District Court for the Northern District of California, San Francisco Division.
The Macevicz patents relate to methods for sequencing DNA using successive rounds of oligonucleotide probe ligation(Sequencing-by-Ligation). The Company’s Genome Analyzer system uses a different technology called DNASequencing-by-Synthesis (SBS), which is not covered by any of these patents. In addition, the sequencing technology originally used by Lynx Therapeutics (called “MPSStm”) is not based on the methods covered by the Macevicz patents. In any event, the Company has never used MPSStm in the Company’s sequencing platform. Furthermore, the Company has no plans to use any of theSequencing-by-Ligation technologies covered by these patents. By these consolidated actions Applied Biosystems is seeking ownership of the Macevicz patents, unspecified costs and damages, and a declaration of non-infringement of these patents. Applied Biosystems is not asserting any claim for patent infringement against the Company.
9.  Collaborative Agreements
deCODE genetics
In May 2006, the Company and deCODE genetics, ehf. (deCODE) executed a Joint Development and Licensing Agreement (the Development Agreement). Pursuant to the Development Agreement, the parties agreed to collaborate exclusively to develop, validate and commercialize specific diagnostic tests for variants in genes involved in three disease-related pathways: the gene-encoding leukotriene A4 hydrolase, linked to heart attack; the gene-encoding transcription factor 7-like 2 (TCF7L2), linked to type 2 diabetes; and the gene-encoding BARD1, linked to breast cancer. The Company and deCODE are developing diagnostic tests based on these variants for use on the Company’s BeadXpress system.
Under the agreement, the Company will be responsible for the manufacturing, marketing and selling of the diagnostic products. The companies will share the development costs of these products and split the profits from sales of the diagnostics tests. The Development Agreement may be terminated as to a particular product under development if one party decides to discontinue funding the development of that product, and may be terminated in whole by either party if the other party commits an uncured material breach, files for bankruptcy or becomes insolvent. Under a separate supply agreement, the Company installed instrumentation at deCODE that will enable deCODE to perform whole genome association studies on up to 100,000 samples using the Company’s Sentrix HumanHap300 BeadChips and associated reagents. The Company has deferred approximately $2.0 million of revenue for instruments installed during the third quarter of 2006 under guidance provided by SFAS No. 48,Revenue Recognition When Right of Return Exists.This amount is classified as a long-term liability as of December 30, 2007. The Company has also deferred approximately $1.3 million of costs related to product shipments to deCODE, which are classified as a long-term asset as of December 30, 2007.
10.  Investment in Genizon BioSciences Inc.
In January 2006, Genizon BioSciences Inc. (Genizon), a Canadian company focused on gene discovery, purchased from the Company approximately $1.9 million in equipment and committed to purchase an additional $4.3 million in consumables. The Company understands that Genizon is using the Company’s products to perform whole-genome and targeted association studies involving thousands of members of the Quebec Founder Population. The goal of the studies is to provide understanding of the genetic origins and mechanisms of common diseases which may then lead to possible drug targets.

ILLUMINA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
In March 2006, the Company entered into a Subscription Agreement for Secured Convertible Debentures with Genizon. Pursuant to the agreement, the Company purchased a Secured Convertible Debenture (the Debenture) of Genizon and certain warrants for CDN $3.5 million (approximately U.S. $3.0 million). The Debenture matures two years from issuance and bears interest, payable semiannually, at a rate of 5% per annum for the first year and 12.5% per annum for the second year. Unless the Debenture is converted before maturity, 112.5% of the principal amount of the Debenture is due upon maturity. The Company also received warrants to purchase 226,721 shares of Genizon Class H Preferred Shares at an exercise price of $1.54 per share.
The Company concluded that the purchase of the Debenture and the concurrent purchase by Genizon of the Company’s products are “linked” transactions under guidance contained in EITFNo. 00-21. Since the transactions are considered “linked,” the Company deferred approximately $3.0 million of revenue (the face value of the Debentures) in the first quarter of 2006, related to the Genizon product shipments. During the fourth quarter of 2007, the Company sold the Debenture and warrants to third party investors for the face value of the Debenture (CDN $3.5 million or approximately U.S. $3.0 million) plus accrued interest, at which time the associated deferred revenue was recognized. Deferred costs of approximately $1.1 million related to product shipments to Genizon were also recognized in the fourth quarter of 2007, as well as approximately $0.5 million of foreign exchange gain due to the appreciation of the Canadian dollar versus the U.S. dollar between the debenture purchase and sale dates.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 a jurisdiction by jurisdictionjurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. As of December 30, 2007, the Company has concluded that it is more likely than not that a significant portion of its deferred tax assets will be realized and, accordingly the Company released a portion of its valuation allowance, approximately $17.1 million of which was recorded as a reduction to the tax provision. Based uponon the available evidence as of December 30, 2007,January 3, 2010, the Company iswas not able to conclude it is more likely than not certain U.S. and foreign deferred tax assets will be realized. Therefore, the Company has

recorded a valuation allowance of approximately $2.9$2.8 million and $25.4$12.1 million against certain U.S. and foreign net deferred tax assets, respectively.
 
As of December 30, 2007,January 3, 2010, the Company had net operating loss carryforwards for federal and state tax purposes of approximately $28.7$25.4 million and $99.1$132.1 million, respectively, which begin to expire in 20252012 and 20152013, respectively, unless previously utilized. In addition, the Company also had U.S. federal and state research and development tax credit carryforwards of approximately $9.2$16.0 million and $9.3$16.2 million, respectively, which begin to expire in 2018 and 2019, respectively, unless previously utilized.
 
As of December 30, 2007,January 3, 2010, the valuation allowance includes approximately $20.2$12.3 million of pre-acquisition foreign deferred tax assets of Solexa.

Pursuant to Section 382 and 383 of the Internal Revenue Code, utilization of the Company’s net operating lossesloss 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. PreviousThe deferred tax assets as of January 3, 2010 are net of any previous limitations due to Section 382 and 383 have been reflected in the deferred tax assets as of December 30, 2007.383.
 
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 2007,2009, the Company realized approximately $20.1$39.3 million of such excess tax benefits, and accordingly recorded a corresponding credit to additional paid in capital. As of December 30, 2007,January 3, 2010, the Company has approximately $11.2$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.

Effective January 1, 2007, the Company adopted FIN No. 48,Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in tax positions. FIN No. 48 requires recognition of the impact of a tax position in the Company’s financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. The adoption of FIN No. 48 did not result in an adjustment to the Company’s opening stockholders’ equity since there was no cumulative effect from the change in accounting principle.

Executive Deferred Compensation Plan
For the Company’s executives and $0, respectively.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.

Investments
At February 19, 2008, the Company held approximately $55.9 million of auction rate securities issued primarily by municipalities and universities. In February 2008, auctions failed for $10.7 million of these auction rate securities and there is no assurance that currently successful auctions on the other auction rate securities in the Company’s investment portfolio will continue to succeed and as a result its ability to liquidate its investment and fully recover the carrying value of the Company’s investment in the near term may be limited or not exist. All of the Company’s auction rate securities, including those subject to the failure, are currently rated AAA, the highest rating, by a rating agency. If the issuers are unable to successfully close future auctions and their credit ratings deteriorate, the Company may in the future be required to record an impairment charge on these investments. The Company believes it will be able to liquidate its investment without significant loss within the next year, and currently believes these securities are not significantly impaired, primarily due to the government guarantee of the underlying securities. However, it could take until the final maturity of the underlying notes (up to 30 years) to realize these investments’ recorded value. Based on the Company’s expected operating cash flows, and its other sources of cash, the Company does not anticipate the potential lack of liquidity on these investments will affect its ability to execute its current business plan.
