Overview

Gilead Sciences, Inc. is a biopharmaceutical company that discovers, develops and commercializes therapeutics to advance the care of patients suffering from life-threatening diseases worldwide. We have six products that are currently marketed in the U.S., fiveall of which are also marketed in other countries worldwide. Our research and clinical programs are focused on anti-infectives, including antivirals and antifungals. We endeavor to grow our existing portfolio of products through proprietary clinical development programs, internal discovery programs and an active product acquisition and in-licensing strategy.

Our worldwide headquarters are in Foster City, California and our European headquarters are in Paris, France. We were incorporated in Delaware on June 22, 1987.

On January 23, 2003, we completed the acquisition of all of the outstanding stocknet assets of Triangle Pharmaceuticals, Inc. (Triangle), which is now a wholly-owned subsidiary of Gilead. to expand our antiviral pipeline. The aggregate preliminary purchase price was $525.0$525.2 million, including the cash paid for the outstanding stock, the fair value of stock options assumed, estimated direct transaction costs and employee terminationrelated costs. Approximately $488.6 million of the purchase price was recorded to in-process research and development expense. Triangle developsdeveloped drug candidates in the antiviral area, with a particular focus on potential therapies for HIV, including AIDS, and the hepatitis B virus. Triangle'sTriangle’s portfolio consistsconsisted of several drug candidates in clinical trials, including emtricitabineEmtrivaTM (emtricitabine) for the treatment of HIV infection, emtricitabine for the treatment of chronic hepatitis B, amdoxovir for the treatment of HIV infection and clevudine for the treatment of chronic hepatitis B. Triangle has filedIn July 2003, the U.S. Food and Drug Administration (FDA) approved for marketing applications for emtricitabineEmtriva for the treatment of HIV and in October 2003, the United States andEuropean Commission granted Marketing Authorisation for Emtriva in all fifteen member states of the European Union. We subsequently returned the rights to amdoxovir and clevudine to the licensors and will have no further commercial interest in these compounds.

In 2002,December 2003, we decided to discontinue selling this product.

In 2003, we earned revenues of $444.3$861.6 million from sales of, and royalties on, these products. Of this amount, sales of Viread generated aggregate product sales and royalty revenues of $225.8$566.5 million, or 48%65% of our total revenues, and sales of AmBisome generated aggregate product sales and royalty revenues of $201.4$210.9 million, or 43%24% of our total revenues. We earned revenues from sales of, and royalties on, all our products in the U.S. of $439.0 million in 2003, $206.4 million in 2002 and $53.3 million in 2001 and $30.5 million in 2000.2001. Outside of the U.S., we earned revenues from sales of, and royalties on, all of our products of $422.6 million in 2003, $237.9 million in 2002 and $160.7 million in 2001 and $143.6 million in 2000.2001.

    Viread (tenofovir disoproxil fumarate)

Viread is an oral formulation of a nucleotide analogue reverse transcriptase inhibitor, tenofovir DF, dosed once a day as part of combination therapy to treat HIV infection in adults. The drug works by blocking reverse transcriptase, an enzyme involved in the replication of HIV. We sell Viread in the U.S. through our U.S. commercial team and in the major European countries through our European commercial team. See "Commercial“Commercial Operations."

The U.S. Food and Drug Administration (FDA)FDA approved Viread for marketing in the U.S. in October 2001 and the European Agency for the Evaluation of Medicinal Products (EMEA) granted similar approval in the European Union in February 2002. In May 2003, the EMEA expanded the indication of Viread to include its use in antiretroviral-naïve HIV infected patients. In August 2003 the FDA similarly expanded the indication of Viread in the U.S. In the U.S., Viread is approved for use in combination with other antiretroviral agents for the treatment of HIV infection. ThisThe indication is based on analyses of plasma HIV RNA levels and CD4 cell counts in a controlled dose-ranging study of Viread of 24 weeks duration (Study 902) and in a controlled, dose-rangingplacebo-controlled study of Viread of 48 weeks duration (Study 907). Both studies were conducted in


treatment-experienced adults with evidence of HIV viral replication despite ongoing antiretroviral therapy.

        Studies in patients who had not previously received antiretroviral therapy, or "antiretroviral-naïve patients," are ongoing. In February 2003, we reported The expanded indication was based on 96-week dataresults from an on-going three-year, randomized, double-blind clinical trial (Study 903) designed to compare the efficacy and safety of a combination treatment regimen of Viread, lamivudine (3TC) and efavirenz to a combination treatment regimen of stavudine (d4T), lamivudine and efavirenz in 600 antiretroviral-naïve patients with HIV infection. In February 2004, we reported 144-week data from this study. Data from Study 903 demonstrates that treatment-naïve patients who received Viread experienced substantially less lipodystrophy and lower elevations in fasting cholesterol and triglyceride levels, as well as improved levels of limb fat and weight gain, while achieving similar reductions in HIV viral load and increases in CD4 cell counts, compared to those who received stavudine. AdverseThe most common adverse events were reported included viral infection, diarrhea and headache, and each occurred with similar frequency in less thanthe two study arms. The discontinuation rate was approximately 18 percent of patients in the Viread arm and included rash, bacterial infection, depression, fever and pneumonia. There was a low discontinuation rate21 percent of approximately 15 percentpatients in each arm of

the study.stavudine arm. This 96-week144-week data supplements the 96 and 48-week results from Study 903 that wewe submitted to the FDA in support of the use of Viread in patients who have not had prior HIV therapy. We intend to submit this 96-week data for potential inclusion in our U.S. and European labels. We cannot predict whether or not the FDA and the EMEA will accept our interpretation of the data and approve a label indicating Viread for use in patients who have not had prior HIV therapy based on such data. Approval of the 48-week data from Study 903 was recommended by the Committee for Proprietary Medicinal Products (CPMP) in February 2003.Viread.

One of the major challenges in treating HIV-infected patients is drug resistance. Because many of the existing therapies for treating HIV infection and AIDS rely on similarly-designed drug processes, patients who have developed resistance to one drug often develop resistance to other drugs within the same class. We believe that Viread, where approved by regulatory authorities, offers advantages over other approved HIV treatments because available data have shown that few patients have developed resistance to Viread and that Viread is effective in treating patients who have developed resistance to other therapies. We cannot be certain, however, that the resistance data we may obtain upon completion of our Phase 3 clinical trials will show similar resistance characteristics to the 48-week data from Study 907 or the data we obtained from the more limited Phase 2 clinical trials.

Another major concern in HIV treatment is convenience of dosing. While combination therapies have a positive impact, they require HIV-infected patients to take numerous drugs. Some of these drugs require multiple doses every day and many have timing and dietary restrictions. This not only results in inconvenience for patients but also contributes to patients missing doses or not adhering to their therapy. Viread is approved to be administered as a once-daily oral pill, which is a schedule that may be appealing to HIV-infected patients and their physicians.

The HIV competitive landscape is becoming more crowded and complicated as treatment trends continue to evolve. TwentyTwenty-two branded anti-HIV drugs are currently sold in the U.S. and many others are in advanceadvanced stages of clinical development. See "Competition."“Competition.”

We have an exclusive, worldwide license to patent rights and related technology for Viread from the Institute of Organic Chemistry and Biochemistry (part of the Academy of Sciences of the Czech Republic) and Rega Stichting v.z.w. (together, IOCB/REGA) and are obligated to pay a percentage of net revenues from sales of Viread in the U.S., the European Union, and any other countries where the product is approved and has patent protection, to IOCB/REGA. See "Academic“Academic and Consulting Relationships—IOCB/REGA."

    Emtriva (emtricitabine)

    Emtriva is an oral formulation of a nucleoside analogue reverse transcriptase inhibitor, dosed once a day as part of a combination therapy to treat HIV infection in adults. We sell Emtriva in the U.S. through our U.S. commercial team and in the major European countries through our European commercial team. See “Commercial Operations.”

    The FDA approved Emtriva for marketing in the U.S. for the treatment of HIV in July 2003 and the European Commission granted Marketing Authorisation for Emtriva in all fifteen member states of the European Union in October 2003.


    Emtriva is an antiviral agent against HIV strains obtained from a geographically diverse set of HIV-infected patients. Laboratory studies have shown that Emtriva shares cross-resistance patterns with lamivudine. The most common resistance mutation to these two agents also reverses resistance of HIV to AZT in some cases. Four Phase 3 clinical studies for Emtriva have been completed, one in collaboration with the Agence Nationale de Recherches sur le Sida (ANRS) in France. One of these studies, Study FTC-301, compared Emtriva (200 mg once-a-day) to stavudine (40 mg twice-a-day) in combination with didanosine (400 mg once-a-day) and efavirenz (600 mg once-a-day) in patients without previous antiretroviral therapy. In July 2002, an independent data safety monitoring board (DSMB) established to provide oversight of the study recommended that Emtriva be offered to all patients enrolled in this study. The interim results evaluated by the study’s DSMB showed that the Emtriva arm was statistically superior to the stavudine arm for primary and secondary endpoints for safety and efficacy. Eighty-seven percent (87%) of the patients in the once-a-day Emtriva arm had persistent virologic response through six months compared to 80% for the twice-daily stavudine arm. Patients in the Emtriva arm also had significant improvements in immunologic function. In view of a compelling difference in favor of the Emtriva arm, the DSMB recommended that the study be amended and all patients were given the option to switch to open-label Emtriva or continue on blinded therapy until the last randomized patient completed week 48 in October 2004. The final analysis of the study confirmed the superior efficacy and safety of Emtriva compared to stavudine in combination with didanosine and efavirenz.

    We have an exclusive, worldwide license to patent rights and related technology for Emtriva from Emory University. See “Academic and Consulting Relationships—Emory University and University of Georgia Research Foundation.”

    AmBisome (amphotericin B liposome for injection)

AmBisome is a proprietary liposomal formulation of amphotericin B. Amphotericin B is a powerful antifungal agent that is known for its ability to treat serious invasive fungal infections caused by various fungal species. These infections are generally life threatening, particularly in patients who have depressed immune systems due to aggressive chemotherapy regimens, stem cell or organ transplant or HIV infection. AmBisomeAmphotericin B treatment also has serious side effects, including kidney toxicity. Studies show, however, that by delivering amphotericin B in our proprietary liposomal formulation, AmBisome reduces the rate and severity of kidney toxicity and injection-related reactions and allows these patients to receive higher doses of amphotericin B.

AmBisome is approved for sale in more than 45 countries, including the U.S., all of the European Union, most of the rest of Europe, Australia, Canada, and several countries in the Middle East, Latin America and Asia. In more than 20 of the countries where AmBisome is approved, including the U.S., we are authorized to promote AmBisome for empirical treatment of fungal infections, i.e. treatment of patients where a strong suspicion, without definite confirmation, exists for a potentially life-threatening invasive fungal infection. In the remaining countries where AmBisome is approved for sale, it is approved for use either as first-line treatment of serious invasive fungal infection or as second-line

3



treatment after conventional amphotericin B therapy fails or when conventional amphotericin B cannot be tolerated. Finally, AmBisome is approved in a number of countries for various other indications, for example, cryptococcal meningitis in AIDS patients, prophylaxis in liver transplant patients and visceral leishmaniasis.

In the U.S., we co-promote AmBisome with Fujisawa through our U.S. commercial team. Our agreement with Fujisawa entitles us to a percentage of revenues generated from these sales and provides that Fujisawa purchases AmBisome from us at our manufacturing cost. See "Collaborative“Collaborative Relationships—Fujisawa." In the major European countries and in Australia, we sell AmBisome through our international commercial teams; in certain other countries we sell AmBisome through independent distributors. Most of our revenues from AmBisome are in Europe, and we expect this to be the case for the foreseeable future.


We have licensed commercial rights for AmBisome in Japan to Sumitomo Pharmaceuticals Co., Ltd. (Sumitomo) in exchange for royalties generated from those activities; however, AmBisome is not yet approved for sale in Japan.

AmBisome faces strong competition from several current competitors, and expected competitors whose treatments are in late stage clinical trials. See "Competition." “Competition.” Competition from these current and expected competitors is likely to erode the revenues we receive from sales of AmBisome.

    Hepsera (adefovir(adefovir dipivoxil)

Hepsera is an oral formulation of a nucleotide analogue HBV DNA polymerase inhibitor, adefovir dipivoxil, dosed once a day to treat chronic hepatitis B. Hepatitis B is caused by the highly contagious hepatitis B virus (HBV) virus and can cause acute liver failure. Some patients develop a chronic hepatitis B infection, which over many years can lead to complications, such as cirrhosis, liver cancer and liver failure, and in approximately 33% of patients can result in death. According to recent estimates from the World Health Organization and the Centers for Disease Control, there are over 400 million people worldwide and about 1.25 million people in the U.S. who have chronic hepatitis B. There are about one million deaths attributable to chronic hepatitis B worldwide each year, and it is one of the ten leading causes of death worldwide. Hepsera disables HBV by interfering with the activity of an enzyme known as HBV polymerase, which is necessary for the virus to replicate.

Our applications for U.S. and European Union marketing authorizations included data from two separate Phase 3 clinical trials designed to evaluate the safety and effectivenessefficacy of Hepsera in a 10mg10 mg dosage for treating patients with the hepatitis B virus. Both of our Phase 3 trials were designed as randomized, double-blind, placebo-controlled studies at clinical sites in the U.S., Canada, Europe, Australia and Southeast Asia. Study 437 evaluated Hepsera for treating patients who test positive for the HBV "e"“e” antigen, the most common type of hepatitis B in the U.S. The other trial, Study 438, evaluated Hepsera for treating patients with a type of hepatitis B known as "precore“precore mutant hepatitis B," the most common in Southeast Asian and the Mediterranean countries. Through 48 weeks, no adefovir-associated resistance mutations were identified in the hepatitis B patients treated in these clinical trials, which suggests that the development of resistance to Hepsera in hepatitis B patients may be delayed and infrequent. Consequently, we believe that Hepsera'sHepsera’s resistance profile could make it an important drug for treating chronic hepatitis B. We cannot be certain, however, that the resistance data we may obtain from the continuing Phase 3 clinical trials on Hepsera will continue to show these resistance characteristics.

Hepsera is approved for sale in the U.S. for the treatment of chronic hepatitis B in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active liver disease. Our U.S. commercial team sells Hepsera in the U.S. In March 2002, we applied for approval by the EMEA of Hepsera for treatment of chronic hepatitis B in the European Union. Approval by the EMEA was recommended by the CPMP

4



Committee for Proprietary Medicinal Products (CPMP) in November 2002 and was received in March 2003. We plan to sell Hepsera in the major European Union countries through our European commercial team.

A vaccine is available that can prevent the transmission of HBV, but it is not effective in people who already have become chronically infected with HBV. We expect that as this vaccine becomes more widely available, the incidence of new hepatitis B infections will decrease. However, even with these advances in the prevention of hepatitis B, the individuals suffering from chronic hepatitis B represent a patient pool with a significant risk of morbidity and mortality due to their underlying chronic viral infection.

Chronic hepatitis B is most common in China and Southeast Asia. In December 2000, we received a clinical trials permit to initiateWe commenced Phase 1 clinical trials in China. We commenced these clinical trialsChina in June 2001. We have licensed the rights to commercialize Hepsera solely for the treatment of hepatitis B in China, Korea, Japan, Taiwan, the rest of Asia, Latin America and certain other territories to GlaxoSmithKline (GSK). As part of our approval to commence Phase 1 clinical trialsTo date, GSK has begun selling Hepsera in Hong Kong, Singapore, the


Philippines, Indonesia and Pakistan. In China, Hepsera was granted Class I designation which, if Hepsera is ultimately approved for sale in China, would give GSK 12 years of market exclusivity for Hepsera with respect to competitors who may otherwise be able to begin clinical development of adefovir dipivoxil following such approval. After receiving the Chinese government'sgovernment’s approval of the Phase 1 study, we were given approval to move forward with the Phase 2/3 program, which beganand completed patient enrollment in December 2002.March 2003.

Several existing therapies for treating patients who are infected with HBV compete with Hepsera. These treatments represent significant competition for Hepsera. See "Competition."“Competition.”

We have an exclusive, worldwide license to patent rights and related technology for adefovir dipivoxil from IOCB/REGA, and pay a percentage of net revenues from sales of Hepsera to IOCB/REGA in countries where the product has patent protection, including the U.S. and the member states of the European Union. In addition, we pay a small variable percentage of net revenues from U.S. sales of Hepsera to the M.D. Anderson Cancer Center. See "Academic“Academic and Consulting Relationships."Relationships—M.D. Anderson Cancer Center.”

    Tamiflu (oseltamivir phosphate)

Tamiflu is an oral pill for the treatment and prevention of influenza A and B. Tamiflu is in a class of prescription drugs called neuraminidase inhibitors that act by disabling all common strains of the flu virus and preventing the virus from spreading in a patient. When used as approved for the treatment of influenza, Tamiflu has been shown to reduce the duration of the flu in adults by an average of 30%, and to reduce the severity of flu symptoms and the incidence of secondary infections. When taken as approved for the prevention of influenza, studies have shown that Tamiflu is up to 92% effective in preventing the development of the flu.

Tamiflu is approved in more than 60 countries, for treatment of influenza, including the U.S., Japan and the European Union for treatment of influenza in children and adults. Tamiflu is also approved in the U.S. and the European Union for the prevention of influenza in adolescents and adults. We developed Tamiflu with Roche, and Roche has the exclusive right to manufacture and sell Tamiflu, subject to its obligation to pay us a percentage of the net revenues that Roche generates from Tamiflu sales. To date, Roche'sRoche’s sales of Tamiflu have been significantly below expectations. Moreover, Roche has experienced problems in the manufacturing and distribution of Tamiflu, which have reduced the net sales on whichand our royalty is based.royalty. This has not had a material effect on our revenues. See "Collaborative“Collaborative Relationships—Roche."

There are several products that have been available to treat the flu for some time, but they have not been shown to be as effective or as safe as neuraminidase inhibitors. See "Competition."“Competition.”

Tamiflu is not being marketed as an alternative to influenza vaccinations. We believe that influenza vaccinations will remain the most effective method of preventing the flu.

    Vistide (cidofovir injection)injection)

Vistide is an antiviral medication for the treatment of CMV retinitis in patients with AIDS. CMV retinitis is a condition characterized by lesions that form on a patient'spatient’s retina that affects persons with weakened immune systems and is most common in patients with AIDS. If left untreated, CMV retinitis can lead to blindness.

Vistide is approved for sale in the U.S., the European Union and several other countries. Demand for Vistide has been low and product revenues are immaterial. Our U.S. commercial team sells Vistide in the U.S. Outside the U.S., PharmaciaPfizer has the exclusive right to sell Vistide. PharmaciaPfizer pays us a percentage of revenues it generates from sales of Vistide. See "Collaborative“Collaborative Relationships—Pharmacia."Pfizer.”


The active agent in Vistide, cidofovir, is being considered as part of the U.S. government strategy for dealing with potential bioterrorism attacks involving smallpox, a life-threatening and highly communicable infectious disease. In laboratory tests, cidofovir has demonstrated activity against all 31 strains of the virus that causes smallpox. In current clinical trials of diluted smallpox vaccine conducted by the National Institute of Allergy and Infectious Diseases, cidofovir is being considered as a potential treatment for vaccinia infection, an adverse reaction sometimes caused by the smallpox vaccine. Additionally, the U.S. National Institutes of Health holds an INDinvestigational new drug application (IND) that allows for the emergency use of cidofovir for smallpox outbreaks without marketing approval from the FDA. We do not know what the efficacy of cidofovir might be in such emergency use, or what side effects, if any, may appear with the use of cidofovir for smallpox. We also cannot predict whether the U.S. or other countries'countries’ governments may stockpile Vistide for the treatment of smallpox.

    DaunoXome (daunorubicin citrate liposome injection)

DaunoXome is a liposomal formulation of the anticancer agent daunorubicin. It is a first-line therapy for treating patients who suffer from certain types of HIV-associated Kaposi'sKaposi’s sarcoma, a disease characterized by widely disseminated lesions in the skin, mucous membranes, lymph nodes and viscera that can be life threatening for patients suffering from AIDS.

DaunoXome is approved for sale in the U.S. and more than 20 other countries. We sellsold DaunoXome in the U.S. and sell it abroad through independent distributors. Demand for DaunoXome has been low and product revenues are immaterial. In December 2003, we made the decision to discontinue selling this product.

We have completed a bioequivalence study, which evaluated the systemic exposure to patients of Triangle, completedthe combination tablet in January 2003. A nucleoside analogue, emtricitabine has been shown to be an inhibitor of HIV and HBV replication in laboratory studies. Emtricitabine is an antiviral agent against HIV strains obtained from a geographically diverse set of HIV-infected patients. Laboratory studies have shown that emtricitabine shares cross-resistance patterns with lamivudine. The most common resistance mutation to these two agents also reverses resistance of HIV to AZT in some cases. Four Phase 3 clinical studies for emtricitabine have been completed, one in collaborationcomparison with the Agence Nationale de Recherches sur le Sida (ANRS)two individual products taken together, and are currently conducting two 48-week trials in France. One of these studies, Study FTC-301, compared emtricitabine (200 mg once-a-day) to stavudine (40 mg twice-a-day) in combination with didanosine (400 mg once-a-day)which Emtriva and efavirenz (600 mg once-a-day) in patients without previous antiretroviral therapy. In July 2002, this Study was unblinded on the recommendation of an independent data safety monitoring board (DSMB) established to provide oversight of the study. The interim results evaluated by the Study's DSMB showed that the emtricitabine arm was statistically superior to the stavudine arm for primary and secondary endpoints for safety and efficacy. Eighty-seven percent (87%) of the patients in theViread are taken together as separate pills.

once-a-day emtricitabine arm had persistent virologic response through six months compared to 80% for the twice-daily stavudine arm. Patients in the emtricitabine arm also had significant improvements in immunologic function. In view of a compelling difference in favor of the emtricitabine arm, the DSMB recommended that the Study be unblinded and all patients be offered the regimen containing emtricitabine.

        An application for marketing approval for emtricitabine was submitted for the treatment of HIV in the U.S. in September 2002 and in the European Union in December 2002. Both applications have been accepted for review. In the U.S., the FDA has advised us that the date for review is July 3, 2003.

    Emtricitabine for Hepatitis B

Emtricitabine has been shown to be an inhibitor of hepatitis B virus replication in patients chronically infected with HBV. We are currently in Phase 3 clinical development of emtricitabine for the treatment of chronic hepatitis B. Some of the development activities undertaken with emtricitabine for the treatment of HIV will also be used in the assessment of emtricitabine for the treatment of chronic hepatitis B.

    Amdoxovir

        We acquired amdoxovir as In November 2003 we announced results from a result48-week clinical trial comparing the efficacy and safety of our acquisition of Triangle, completedemtricitabine 200 mg once a day versus placebo in January 2003. Amdoxovir is a purine dioxolane nucleoside that may offer advantages over other nucleosides currently in the market because of its activity against drug resistant viruses as exhibited in laboratory studies. In early 2002, Triangle initiated two Phase 2 clinical trials on amdoxovir. In August 2002, the FDA placed the clinical development program for amdoxovir on partial clinical hold as a result of concerns over lenticular opacities, a possible side effect characterized by clouding of the lens of the eye. The extent to which amdoxovir increased the occurrence of lenticular opacities in248 patients receiving amdoxovir, if at all, is unknown. Patients in clinical studies who are benefiting from amdoxovir and new studies involving patients who have failed other treatments that contained a drug from each currently approved class of anti-HIV medications and require amdoxovir in their regimens may continue on treatment. Discussions with the FDA regarding the partial clinical hold are planned.

    Clevudine

        We acquired clevudine as a result of our acquisition of Triangle, completed in January 2003. Clevudine is a pyrimidine nucleoside analogue and has been shown to be a potent inhibitor ofchronic hepatitis B virus replication in laboratory studies. In November 1999, Triangle initiated(Study FTCB-301). We believe that a second Phase 1 studies,3 clinical trial will be necessary before emtricitabine could be submitted for review to any regulatory agency. This second Phase 3 trial has not yet been designed and we are currently conducting Phase 2 clinical trials of clevudinethe strategy for emtricitabine for the treatment of chronic hepatitis B. Chronic toxicology studies have been completed and reproductive toxicology studies are in progress.B is still evolving.

    GS 7340

GS 7340 is a novel nucleotide analogue reverse transcriptase inhibitor that, when processed in the body, yields tenofovir, the active chemical yielded by Viread, selectively within lymphatic cells. The chemical composition of GS 7340 however, may allow it to cross cell membranes more easily than Viread, leading to greater potency than Viread. In the first quarter of 2002, we beganBased on data from our Phase 1/2 clinical trials of GS 7340, we have begun developing a Phase 2 program for the treatment of HIV infection.infection which will evaluate patients who are treatment naive and those who are highly resistant to thymidine analogues.

Research & Development

We are seeking to add to our existing portfolio of products through our internal discovery and clinical development programs and through an active product acquisition and in-licensing strategy, such as our acquisition of Triangle completed in January 2003. We have research scientists in Foster City and San Dimas, California and Durham, North Carolina engaged in the discovery and development of new molecules and technologies that we hope will lead to new medicines and novel formulations of existing drugs. Our therapeutic focus is in the areas of life

threatening infectious diseases. In total, our research and development (R&D) expenses for 20022003 were $134.8$164.9 million, compared with $134.8 million for 2002 and $185.6 million for 2001 and $132.3 million for 2000.2001.

    Nucleotide Analogues

Our scientists are working with our proprietary nucleotide analogues to develop treatments for viral infections. These compounds treat viral infections by interfering with the activity of certain enzymes that are necessary for the virus to grow.

We believe that small molecule nucleotide analogues can offer advantages as therapeutics. First, these molecules have demonstrated ability to work in both infected and uninfected cells. This could enable us to develop drugs that not only treat a patient who is infected with a virus but that can also prevent a healthy person from becoming infected in the first place. Second, drugs developed using these molecules have been shown to have treatment activity in a patient for longer periods of time than other available drugs. This could enable us to develop drugs that require less frequent dosing and are thus more convenient for patients.

    HIV Protease Inhibitors

We are evaluating a number of small molecule compounds known as "protease inhibitors"protease inhibitors for the potential treatment of HIV infection. Protease inhibitors act by interfering with the activity of protease, an enzyme that, like reverse transcriptase, is necessary for replication of HIV. We have conducted a number of preclinical experiments on these compounds and have demonstrated that they have potent antiviral activity. Our lead candidate is GS 224338,9005 (formerly known as GS 4338), which is currently undergoing extensive preclinical evaluations. We submitted an investigational new drug application to the FDA for GS 9005 in January 2004.

    Other Antiviral Research

We are undertaking additional research in the area of treatment of viral diseases. Many of these efforts focus on potential targets in HIV for therapeutic drugs.

Liposomes

We also have scientists focused on applying our proprietary liposomal drug delivery technology to develop safer, more effective and more convenient drugs. Liposomes are sub-microscopic hollow spheres into which drugs can be packed. We believe, and oursignificant research supports our belief, that we can influence the way compounds are released and distributed in the body by placing them in liposomes. This can, in turn, improve the safety and treatment benefits of such compounds.efforts aimed at hepatitis C viral infection. See “Collaborative Relationships—Chiron Corporation.”

Commercial Operations

We have U.S. and international commercial sales operations. We have marketing subsidiaries in the United Kingdom, Germany, Italy, Spain, France, Portugal, Greece and Australia. Our commercial teams promote and sell Viread, Emtriva, Hepsera and AmBisome in the U.S., and Viread and AmBisome in Europe and Australia. AmBisome is also sold by Fujisawa in the U.S. and by Sumitomo in Japan. GSK will promote and sell Hepsera in Asia and South America. We sell Vistide and DaunoXome in the U.S;U.S and our commercial partner, Pharmacia,Pfizer, sells Vistide outside of the U.S.; and, we sell DaunoXome outside of the U.S. through independent distributors. Our commercial partner, Roche, promotes and sells Tamiflu everywhere it is sold. Japan Tobacco Inc. (Japan Tobacco) will promote and sell Viread and Emtriva in Japan when approved by Japanese regulatory authorities.


Our commercial teams promote Viread, Emtriva and Hepsera through direct field contact with physicians, hospitals, clinics and other healthcare providers who are involved in the treatment of patients with HIV (for Viread) or chronic hepatitis B (for Hepsera). They also promote AmBisome to infectious disease specialists, hematologists, intensive care units, hospitals, home health care providers and cancer specialists.

        We have international commercial operations in Europe and Australia. The European commercial team is supported by medical, operational,sales operations, marketing, financial, regulatory, legal affairs, manufacturing and human resources and information technology personnel located primarily in our European headquarters in Paris, France. The U.S. and Australian commercial teams are supported by our worldwide headquarters in Foster City, California. In some countries outside of the U.S., we have agreements with third-party distributors, including distributors in certain of the countries where we have marketing operations, to promote, sell and distribute Viread, AmBisomeEmtriva, Hepsera and DaunoXome.AmBisome. These international distribution agreements generally provide that the distributor has the exclusive right to sell Viread, AmBisomeEmtriva and DaunoXomeAmBisome in a particular country or several countries for a specified period of time.

In January 2003, we announced a program pursuant to which we will be selling Viread at our cost to all countries in Africa and to the 15 other countries designated "Least“Least Developed Countries"Countries” by the United Nations. We are taking steps to ensure that the Viread product sold under this program is used to serve patients in the developing world and not diverted to other markets. See "International“International Distribution."

To support and expand the commercialization of Viread, Hepsera and Hepsera,Emtriva, we have significantly increased our sales force in the U.S. and are devoting additional marketing resources in the U.S. to improve our coverage of healthcare professionals treating HIV-infected and HBV-infected patients. We have also significantly increased the size of our commercial operations in Europe to manage the commercialization of Viread, Emtriva and the anticipated commercialization of Hepsera in the European Union. It is our current intention to retain the commercial rights to Hepsera and market it directly or through distributors in the U.S., Canada, Europe, Australia, New Zealand and Turkey.

In April 2002, we entered into a licensing agreement with GSK, under which GSK received theexclusive rights to commercialize Hepsera in Asia, Latin America, Africa and certain other territories. Under the agreement, we retained rights to Hepsera in the U.S., Canada, Eastern and Western Europe, Australia, New Zealand and Turkey. GSK also received exclusive rights to develop Hepsera solely for the treatment of chronic hepatitis B in all other countries, the most significant of which include China, Korea, Japan and Taiwan. GSK will have full responsibility for development and commercialization of Hepsera in its territories.

In July 2003, we entered into a licensing agreement with Japan Tobacco under which Japan Tobacco will commercialize products in Gilead’s HIV portfolio in Japan. The agreement includes Viread, Emtriva and a future co-formulation of the two products. Japan Tobacco has submitted an application for Viread and expects to submit an application for Emtriva and co-formulation of the two products to Japanese regulatory authorities this year.

In the U.S., Viread, Hepsera, Emtriva, Vistide and VistideDaunoXome are returnable in their original, unopened containers after expiration up to one year beyond the expiration date or, if damaged when received by the customer. Our customers may return AmBisome or DaunoXome if the shelf life has expired or if the product is damaged or defective when the customer receives it. AmBisome has an approved shelf life of 36 months in the U.S. and 30 months in most European countries. DaunoXome has a shelf life of 52 weeks in the U.S. and most European countries. Viread has a shelf life of 24 months in the U.S. and the European Union. Hepsera has a shelf life of 24 months in the U.S. Additionally, certain governmental agency customers and state AIDS drug assistance programs are entitled to or receive discounts,the European Union. Emtriva has a shelf life of 24 months in the U.S. and we are required to provide rebates under state Medicaid programs.the European Union. To date, returns, rebates and discounts have not been material to our financial results. Fujisawa establishes the return policy for AmBisome in North America, and Roche establishes the return policy for Tamiflu. At the end of each flu season, there have been significant returns of Tamiflu to Roche, which reducesreduce the net sales on which our royalty from Roche is based.


Additionally, certain governmental agency customers and state AIDS drug assistance programs are entitled to or receive discounts, and we are required to provide rebates under state Medicaid programs. We believe that we provide adequate provisions for these discounts and rebates in accordance with our revenue recognition policy.

Collaborative Relationships

As part of our business strategy, we establish collaborations with other companies to assist in the clinical development and/or commercialization of certain of our products and product candidates and to provide support for our research programs. We also evaluate opportunities for acquiring from other companies products or rights to products and technologies that are complementary to our business. The

Academic and Consulting Relationships

To supplement our research and development efforts, as part of our regular business we enter into arrangements with universities and medical research institutions. These arrangements often provide us with rights to patents, patent applications and technology owned by these institutions in return for payments and fees relating to our use of these rights.

Emory University and University of Georgia Research Foundation, Inc.

Emtricitabine.   In April 1996, Triangle obtained, and we acquired as part of our acquisition of Triangle, an exclusive worldwide license to all of Emory University'sUniversity’s rights to purified forms of emtricitabine for use in the HIV and the hepatitis B fields. We are obligated to make certain milestone and royalty payments to Emory, including annual minimum royalties beginning the third year after the first FDA registration is granted for an anti-HIV product incorporating the emtricitabine technology in the U.S. and the third year after the first registration is granted for an anti-hepatitis B product incorporating the emtricitabine technology in certain major market countries, for the HIV and hepatitis B indications,


respectively. In 2002, Triangle began paying license maintenance fees because development milestones had not yet been achieved.

In May 1999, Emory and GSK settled their litigation pending in the United States District Court relating to emtricitabine, and we became the exclusive licensee of all U.S. and foreign patents and patent applications filed by Burroughs Wellcome Co. on the use of emtricitabine to treat hepatitis B.

12



Under the license and settlement agreements, we and Emory were also given access to development and clinical data and drug substance held by GSK relating to emtricitabine.

In May 2002, Emory, GSK and Shire Pharmaceuticals Group, plc (Shire) settled worldwide patent disputes involving lamivudine and emtricitabine. Under the terms of the settlement, Emory received an exclusive license from Shire under Shire'sShire’s patents relating to emtricitabine and methods for its use and manufacture and Shire and GSK received exclusive licenses under Emory'sEmory’s patents relating to lamivudine. Under the terms of our license agreement with Emory, we automatically acquired an exclusive sublicense to the Shire patents relating to emtricitabine granted under the terms of the settlement, thereby resolving all previously pending patent disputes regarding emtricitabine.

        Amdoxovir.    In March 1996, Triangle entered into, and we acquired as part of our acquisition of Triangle, aThe license agreement with Emory and the University of Georgia Research Foundation, Inc. (UGRF) pursuant to which we received an exclusive worldwide license to all of Emory's and UGRF's rights to a series of nucleoside analogues including amdoxovir and DXG (i.e., the active anti-HIV agent) for use in the HIV and hepatitis B fields. We are obligated to make milestone and royalty payments to Emory and UGRF. In March 1999, Triangle began paying license maintenance fees because development milestones had not yet been achieved. Beginning the third year after the first FDA registration is granted for an FDA-approved product incorporating the amdoxovir technology, we will be required to pay Emory and UGRF a minimum annual royalty.

        On August 30, 2002, Triangle resolved outstanding patent disputes involving amdoxovir with Shire. Under the terms of the settlement, Emory and UGRF received an exclusive license to Shire's patent rights covering amdoxovir and methods for its use and manufacture. Under the terms of this license agreement, we acquired an exclusive sublicense to these rights in exchange for an obligation to pay Shire an incremental royalty on future amdoxovir sales. Under the settlement agreement, Emory, UGRF and Gilead granted Shire an exclusive license under their patent rights to BCH-13520 and methods for its use and manufacture.

        Both of the license agreements with Emory terminateterminates upon the later of patent expiration or the expiration of our obligation to pay royalties. In addition, we have the right to terminate the agreement in its entirety or with respect to one or both indications (HIV and HBV) in one or more countries prior to expiration at any time upon 90 days notice.

Amdoxovir.   In March 1996, Triangle entered into, and we acquired as part of our acquisition of Triangle, a license agreement with Emory and the University of Georgia Research Foundation, Inc. (UGRF) pursuant to which we received an exclusive worldwide license to all of Emory’s and UGRF’s rights to a series of nucleoside analogues including amdoxovir and DXG (i.e., the active anti-HIV agent) for use in the HIV and hepatitis B fields. In March 1999, Triangle began paying license maintenance fees because development milestones had not yet been achieved. In January 2004, we announced our intent to terminate the license agreement for amdoxovir.

M.D. Anderson Cancer Center

In 1994, we entered into an agreement with the M.D. Anderson Cancer Center relating to Hepsera. Under this agreement, we currently pay M.D. Anderson Cancer Center a percentage of net revenues based upon sales of Hepsera. The agreement with M.D. Anderson Cancer Center terminates the later of patent expiration or ten years from first commercial sale.

IOCB/REGA

In 1991 and 1992, we entered into agreements with IOCB/REGA relating to Viread, Hepsera and Vistide. Under these agreements, we received from IOCB/REGA the exclusive right to manufacture, use and sell the nucleotide compounds covered by these agreements. We currently pay 3%a percentage of net revenues based upon sales of Viread, Hepsera and Vistide to IOCB/REGA. The agreements with IOCB/REGA terminate on an individual country basis the later of patent expiration or ten years from first commercial sale. In addition, IOCB/REGA may terminate the licenses for a particular product in a key market in the absence of commercial sales of that product within 12 months after regulatory approval.

University License Equity Holdings, Inc.

We have an ongoing collaborative arrangement with University License Equity Holdings, Inc. (ULEHI), (“ULEHI”), the successor to University Technology Corporation and its predecessor University Research Corporation, a technology holding company for the University of Colorado at Boulder, relating to its SELEX technology to identify aptamers. Under this arrangement, ULEHI has granted us all of its present


and future rights to inventions covered by patents and patent applications for SELEX technology, improvements to SELEX technology it makes or discovers, oligonucleotides or other molecules it makes using SELEX technology and computer software related to SELEX technology. We are required to pay ULEHI certain variable royalties based on revenues generated from sales of products derived using the SELEX technology.

Developing World Collaborations

The Bill & Melinda Gates Foundation & Family Health International

In October 2002, we entered into an agreement with the Bill & Melinda Gates Foundation and Family Health International (FHI) to provide Viread for FHI'sFHI’s multinational clinical trial evaluating Viread'sViread’s effectiveness as a method of reducing the risk of HIV infection among sexually active adults who are regularly exposed to HIV. The clinical trials, to be conducted by FHI, are funded by a $6.5 million, three-year grant from the Gates Foundation.

The DART Study

In November 2002, we entered into a collaborative agreement with the Medical Research Council (MRC) of the United Kingdom, Boehringer Ingelheim GmBH, and GSK in connection with a five-year clinical study conducted by the MRC on antiretroviral HIV therapy in Africa. The trial is called the DART Trial (Development(Development of AntiRetroviral TherapyAntiRetroviral Therapy in Africa) and is aimed at studying clinical versus laboratory monitoring practices, and structured treatment interruptions versus continuous antiretroviral therapy in adults with HIV infection in sub-Saharan Africa. We will provide Viread at no cost for the DART study.

The Institute for One World Health

In January 2003, we entered into an agreement with the Institute for One World Health, pursuant to which we will provide AmBisome at our cost for a Phase 3 clinical trial evaluating AmBisome for the treatment of visceral leishmaniasis with paromomycin in India, which has the greatest global burden of visceral leishmaniasis. The clinical trial will be conducted by the Institute for One World Health in partnership with the World Health Organization.

International Distribution

We have various agreements with distributors in Europe, Asia, Latin America, the Middle East and Africa that grant these distributors the exclusive right to sell AmBisome,Viread, Emtriva, Hepsera and in some cases DaunoXome,AmBisome in a particular country or countries for a specified period of time. Most of these agreements also provide for collaborative efforts between us and the distributor for obtaining regulatory approval for the product in the particular country and for marketing the product in the country. Most of these agreements establish a price that the distributor must pay for our product and require us to deliver quantities of the product ordered by the distributor. We entered into similar distribution agreements for Viread in countries where we do not promote and sell it directly.

        In January 2003, we announced a program pursuant to which we will supply Viread at our cost to all countries in Africa and to the 15 other countries designated "Least Developed Countries" by the United Nations. This humanitarian effort is in recognition of the extreme impact HIV disease has had in these resource-poor countries. Over 70% of the world's cases of HIV are located in these countries.

14



We are taking steps to ensure that the Viread product sold under this program is used to serve patients in the developing world and not diverted to other markets.

Manufacturing

AmBisome and DaunoXome

We manufacture AmBisome and DaunoXome in commercial quantities in two separate but adjacent facilities in San Dimas, California. The Medicines Control Agency of the United Kingdom and the FDA have approved the commercial production of each of AmBisome and DaunoXome in the facility in which it is produced. To import AmBisome and DaunoXome into the European Union, we own a manufacturing facility in Dublin, Ireland where we perform quality control testing, final labeling, packaging and distribution for the European Union and elsewhere. We have discontinued manufacturing DaunoXome.

14



We use commercially available materials and equipment to manufacture these products. Currently, we obtain the amphotericin B that we use to manufacture AmBisome, the daunorubicin HCl and distearoylphosphatidylcholine that we use to manufacture DaunoXome, and the cholesterol that we use to manufacture both AmBisome and DaunoXome from single approved suppliers.

AmBisome is sold as a freeze-dried product. We currently freeze-dry some AmBisome at our San Dimas manufacturing facility and also use a third party to freeze-dry additional product.product as needed. Given our current projections for growth in AmBisome demand, we believe we have sufficient capacity to meet future demand. We also have the option of installing additional freeze-drying capacity in San Dimas should such additional supply become necessary. WereIf we to provewere unable to install additional freeze-drying capacity in San Dimas or locate appropriate third parties to meet this need, our ability to meet increased AmBisome demand would be diminished. Manufacturing liposomal products is a particularly complex process and any new liposomal product we develop will require unique and complex variations in our manufacturing process.

Antiviral Products

We contract with third parties to manufacture our antiviral drugs for clinical and commercial purposes, including Viread, Emtriva, Hepsera Vistide, emtricitabine, amdoxovir and clevudine.Vistide.

We manufacture Viread tablets through a single contract manufacturer for the U.S., and the European Union and for sales and distribution in other territories. In addition, we have a second contract manufacturer in Europe for European Union distributed product. All have been approved by their respective agencies.

We have obtained qualification in the U.S. and are seeking qualification in the European Union for two contract manufacturers for adefovir dipivoxil, the active ingredient in Hepsera. We have one contract manufacturer for the final Hepsera drug product for commercial supply and are seeking to qualify a second supplier.

We entered into an agreement with Abbott Laboratories (Abbott) to manufacture emtricitabine bulk drug substance and final drug product for us. We have qualified a second contract manufacturer for bulk drug substance in both the U.S. and the European Union.

We have two suppliers that have been approved by the FDA and the European Union to manufacture cidofovir bulk drug substance, which is used in Vistide. We have a single FDA and EMEA approved supplier for Vistide drug product.

In January 2002, Roche announced that, due to production problems, the liquid suspension form of Tamiflu approved for treatment of children as young as one year-old was not available; however, the liquid suspension form of Tamiflu was returned to market in time for the 2002-2003 flu season. These production issues did not affect availability of the tablet form of Tamiflu for adults and adolescents 13 years and older. In Japan, where the 2002-2003 flu season has beenwas particularly severe, Roche'sRoche’s sublicensee, Chugai Corporation, has beenwas unable to meet the heightened demand satisfactorily. In January 2003, Chugai issued a press release attributing this failure, in part, to manufacturing problems. In November 2003, Chugai announced a recall of Tamiflu. These problems in Japan have reduced the net sales on whichand royalty from Roche. While royalties from Roche for Tamiflu have been below our royalty with Roche is based. Toexpectations, to date, these production and commercialization issues have not had a material effect on our earnings, and we do not expect them to have a material effect on our earnings in the future.

15



        We entered into an agreement with Abbott to manufacture emtricitabine bulk drug substance and final drug product for us. We are currently seeking qualification of Abbott in the U.S. and the European Union as a contract manufacturer. We are also seeking qualification in the European Union for a second contract manufacturer for emtricitabine bulk drug substance. Abbott has a recent history of violations of current Good Manufacturing Practice regulations cited by the U.S. FDA and has been working towards corrections under an FDA consent decree. The FDA conducted a pre-approval inspection at Abbott for the new drug application of emtricitabine and issued a Form 483 observation to Abbott in December 2002. In January 2003, Abbott submitted a response to the Form 483 observation. If the FDA deems Abbott's response to the Form 483 observation to be inadequate, or if Abbott is unable to supply the initial launch quantities of emtricitabine in a timely manner, the emtricitabine launch could be delayed.

        We have two suppliers that have been approved by the FDA and the European Union to manufacture the cidofovir used in Vistide. We have a single FDA and EMEA approved supplier for the final Vistide drug product.

We have no commercial-scale manufacturing facilities for our antiviral products, and we have no current plans to establish such facilities.products. For our future antiviral products, we will need to develop additional manufacturing capabilities and establish additional third party suppliers in order to manufacture sufficient quantities of our product candidates to undertake clinical trials and to manufacture sufficient quantities of any products that are approved for commercial sale. If we are unable to develop manufacturing capabilities internally or contract for large scale manufacturing with third parties on acceptable terms for our future antiviral products, our ability to conduct large-scale clinical trials and meet customer demand for commercial products would be adversely affected.


We believe that the technology we use to manufacture our products and compounds is proprietary. For our antiviral products, we have disclosed all necessary aspects of this technology to contract manufacturers to enable them to manufacture the products and compounds for us. We have agreements with these manufacturers that are intended to restrict them from using or revealing this technology, but we cannot be certain that these manufacturers will comply with these restrictions. In addition, these manufacturers could develop their own technology related to the work they perform for us that we may need to manufacture our products or compounds. We could be required to enter into an agreement with that manufacturer if we wanted to use that technology ourselves or allow another manufacturer to use that technology. The manufacturer could refuse to allow us to use their technology or could demand terms to use their technology that are not acceptable.

We believe that we are in compliance with all material environmental regulations related to the manufacture of our products.

Patents and Proprietary Rights

Patents and other proprietary rights are very important to our business. If we have a properly designed and enforceable patent it can be more difficult for our competitors to use our technology to create competitive products and more difficult for our competitors to obtain a patent that prevents us from using technology we create. As part of our business strategy, we actively seek patent protection both in the U.S. and internationally and file additional patent applications, when appropriate, to cover improvements in our compounds, products and technology. We also rely on trade secrets, internal know-how, technological innovations and agreements with third parties to develop, maintain and protect our competitive position. Our ability to be competitive will depend on the success of this strategy.

We have a number of patents, patent applications and rights to patents related to our compounds, products and technology, but we cannot be certain that issued patents will be enforceable or provide adequate protection or that pending patent applications will result in issued patents. The following

16



table shows the actual or estimated expiration dates in the U.S. and Europe for the primary patents and for patents that may issue under pending applications that cover the compounds in our marketed products and our product candidates:

Patents covering Viread, Hepsera, Vistide emtricitabine, clevudine and amdoxovirEmtriva are held by third parties. We acquired exclusive rights to these patents in the agreements we have with these parties. See "Collaborative Relationships"“Collaborative Relationships” and "Academic“Academic and Consulting Relationships." Patents do not cover the active ingredients in AmBisome and DaunoXome.AmBisome. Instead, we hold patents to the liposomal formulations of these compoundsthis compound and also protect these formulations through trade secrets. We do not have patent filings covering all forms of Hepsera in China or in certain other Asian countries, although we do have applications pending in various Asian countries, including China, that relate to specific forms and formulations of Hepsera. Asia is a major market for HBV therapies.

We may obtain patents for our compounds many years before we obtain marketing approval for them. This limits the time that we can prevent other companies from developing these compounds and therefore


reduces the value of the product. However, we can apply for patent term extensions. For example, extensions for the patents on Vistide have been granted in the U.S. and a number of European countries, compensating in part for delays in obtaining marketing approval. Similar patent term extensions may be available for other products that we are developing, but we cannot be certain we will obtain them.

It is also very important that we do not infringe patents or proprietary rights of others and that we do not violate the agreements that grant proprietary rights to us. If we do infringe patents or violate these agreements, we could be prevented from developing or selling products or from using the processes covered by those patents or agreements, or we could be required to obtain a license from the third party allowing us to use their technology. We cannot be certain that, if required, we could obtain a license to any third-party technology or that we could obtain one at a reasonable cost. If we were not able to obtain a required license, we could be adversely affected. Because patent applications are confidential for at least some period of time, including sometimes in the U.S. until a patent issues, there may be pending patent applications from which patents will eventually issue and prevent us from developing or selling certain products unless we can obtain a license to use the patented technology.

Patents relating to pharmaceutical, biopharmaceutical and biotechnology products, compounds and processes such as those that cover our existing compounds, products and processes and those that we

17



will likely file in the future, do not always provide complete or adequate protection. Future litigation or reexamination proceedings regarding the enforcement or validity of our existing patents or any future patents could invalidate our patents or substantially reduce their protection. In addition, our pending patent applications and patent applications filed by our collaborative partners may not result in the issuance of any patents or may result in patents that do not provide adequate protection. As a result, we may not be able to prevent third parties from developing the same compounds and products that we are developing.

We also rely on unpatented trade secrets and improvements, unpatented internal know-how and technological innovation. In particular, a great deal of our liposomal manufacturing expertise, which is a key component of our liposomal technology, is not covered by patents but is instead protected as a trade secret. We protect these rights mainly through confidentiality agreements with our corporate partners, employees, consultants and vendors. These agreements provide that all confidential information developed or made known to an individual during the course of their relationship with us will be kept confidential and will not be used or disclosed to third parties except in specified circumstances. In the case of employees, the agreements provide that all inventions made by the individual while employed by us will be our exclusive property. We cannot be certain that these parties will comply with these confidentiality agreements, that we would have adequate remedies for any breach, or that our trade secrets will not otherwise become known or be independently discovered by our competitors. Under some of our research and development agreements, inventions discovered in certain cases become jointly owned by us and our corporate partner and in other cases become the exclusive property of one of us. It can be difficult to determine who owns a particular invention, and disputes could arise regarding those inventions.

Competition

Our products and development programs target a number of diseases and conditions, including viral fungal and bacterialfungal infections. There are many commercially available products for these diseases, and a large number of companies and institutions are spending considerable amounts of money and other resources to develop additional products to treat these diseases. Our current products compete with other available products based primarily on:

    ·efficacy;

    ·       safety;



    safety;

·tolerability;

·acceptance by doctors;

·patient compliance;

·patent protection;

·ease of use;

·price;

·insurance and other reimbursement coverage;

·distribution;

·marketing; and

·adaptability to various modes of dosing.

Any other products we market in the future will also compete with products offered by our competitors. If our competitors introduce data that shows improved characteristics of their products,

18



improve or increase their marketing efforts or simply lower the price of their products, sales of our products could decrease. We also cannot be certain that any products we may develop in the future will compare favorably to products offered by our competitors or that our existing or future products will compare favorably to any new products that are developed by our competitors. Our ability to be competitive also depends upon our ability to attract and retain qualified personnel, to obtain patent protection or otherwise develop proprietary products or processes and to secure sufficient capital resources for the substantial period that it takes to develop a product.

        Viread.Viread and Emtriva.   The HIV competitive landscape is becoming more crowded and complicated as treatment trends continue to evolve. A growing number of anti-HIV drugs are currently sold or are in advance stages of clinical development. Of the 2022 branded drugs available in the U.S., Zerit (stavudine, d4T) sold by Bristol-Myers Squibb (BMS) and the fixed combination products, Combivir (AZT and 3TC) and Trizivir (AZT, 3TC, ABC), both sold by GSK, represent the most direct competition for Viread. These companies are in the process of launching formulations of existing drugs now indicated by the FDA for once-daily oral dosing. These include GSK'sGSK’s 300 mg dose of Epivir (3TC) and BMS'sBMS’s new extended release formulation of Zerit. Antiretroviral product candidates that are expected to enter the market in the next few yearsOther recently approved antiretroviral products include atazanivir (QD protease inhibitor from BMS), and Fuzeon (injectable integrase inhibitor from Roche/Trimeris). GSK is also pursuinghas filed an application for approval of a once-daily dose of Ziagen (abacavir), as well as a new fixed dose combination of Ziagen and Epivir. Other companies competing in the HIV therapeutic category are Pfizer, Merck, Boehringer-Ingelheim and Abbott Laboratories.Abbott.

AmBisome.   AmBisome faces strong competition from several current and expected competitors. Current competitors include:

·


Presently unapproved but expected competitors include a class of treatments called echinocandins, including Fujisawa'sFujisawa’s micafungin, which received marketing approval in Japan in October 2002 and is under submissionreview for regulatory approval in the U.S. and Canada, and anidulafungin, a Vircuron, Inc. (formerly Versicor, Inc.) product candidate, which is being evaluated in multiple late-stage clinical trials. Finally, Schering Plough is developing Noxafil (posaconazole), which is currently in Phase 3 trials. Competitiontrials.Competition from these current and expected competitors has eroded and is likely to continue to erode the revenues we receive from sales of AmBisome.

Hepsera.   Hepsera faces significant competition from existing therapies for treating patients who are infected with HBV. Most significantly:

·

19


    Hepsera may also facesface competition from clinical-stage candidates, including Bristol-Myers Squibb'sSquibb’s entecavir and Idenix'sIdenix’s LdT, two oral nucleoside analogues currently in Phase 3 trials. Other competition includes Roche'swill include Roche’s Pegasys (pegylated interferon alfa-2a), which is currently being studied for chronic hepatitis B.

    Tamiflu.   Tamiflu competes with Relenza, an anti-flu drug that is sold by GSK. Relenza is a neuraminidase inhibitor that is delivered as an orally-inhaled dry powder. In addition, BioCryst Pharmaceuticals is developing a neuraminidase inhibitor anti-flu drug, peramivir, that will represent significant competition, when and if the FDA approves it. This drug may be administered as a once-daily pill, as opposed to Tamiflu, which must be taken twice daily for treatment. We cannot be certain that Tamiflu will compare favorably to this drug based on performance, price, length of dosing, side effects or any other criteria.

    Vistide.    Vistide competes   Vistidecompetes with a number of drugs that also treat CMV retinitis, including ganciclovir, sold in intravenous and oral formulations by Roche and as an ocular implant by Bausch & Lomb Incorporated; valganciclovir, also marketed by Roche; foscarnet, an intravenous drug sold by AstraZeneca; and, formivirsen, a drug injected directly into the eye sold by CibaVision.

            DaunoXome.    DaunoXome competes with or is expected to compete with a number of drugs that have been approved, or are awaiting approval, for the treatment of Kaposi's sarcoma in the U.S. and Europe, including Doxil, a product of Ortho Biotech that, like DaunoXome, is sold in a liposomal formulation.

    A number of companies are pursuing the development of technologies competitive with our research programs. These competing companies include specialized pharmaceutical firms and large pharmaceutical companies acting either independently or together with biopharmaceutical companies. Furthermore, academic institutions, government agencies and other public and private organizations conducting research may seek patent protection and may establish collaborative arrangements for competitive products and programs.

    We anticipate that we will face increased competition in the future as our competitors introduce new products to the market and new technologies become available. We cannot determine if existing products or new products that our competitors develop will be more effective or more effectively marketed and sold than any that we develop. Competitive products could render our technology and products obsolete or noncompetitive before we recover the money and resources we used to develop these products.

    Government Regulation

    Our operations and activities are subject to extensive regulation by numerous government authorities in the U.S. and other countries. In the U.S., drugs are subject to rigorous FDA regulation. The Federal Food, Drug and Cosmetic Act and other federal and state statutes and regulations govern the testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of our products. As a result of these regulations, product development and the product approval process is very expensive and time consuming.

    20


    The FDA must approve a drug before it can be sold in the U.S. The general process for this approval is as follows:


    Preclinical Testing

    Before we can test a drug candidate in humans, we must study the drug in laboratory experiments and in animals to generate data to support the drug'sdrug’s potential safety and benefits. We submit this data to the FDA in an investigational new drug application (IND) seeking their approval to test the compound in humans.

    Clinical Trials

    If the FDA accepts the investigational new drug application, we study the drug in human clinical trials to determine if the drug is safe and effective. These clinical trials involve three separate phases that often overlap, can take many years and are very expensive. These three phases, which are themselves subject to considerable regulation, are as follows:

      ·Phase 1.   The drug is given to a small number of healthy human subjects or patients to test for safety, dose tolerance, pharmacokinetics, metabolism, distribution and excretion.

      ·Phase 2.   The drug is given to a limited patient population to determine the effect of the drug in treating the disease, the best dose of the drug, and the possible side effects and safety risks of the drug.

      ·Phase 3.   If a compound appears to be effective and safe in Phase 2 clinical trials, Phase 3 clinical trials are commenced to confirm those results. Phase 3 clinical trials are long-term, involve a significantly larger population, are conducted at numerous sites in different geographic regions and are carefully designed to provide reliable and conclusive data regarding the safety and benefits of a drug. It is not uncommon for a drug that appears promising in Phase 2 clinical trials to fail in the more rigorous and reliable Phase 3 clinical trials.

    FDA Approval Process

    If we believe that the data from the Phase 3 clinical trials show an adequate level of safety and effectiveness, we will file a new drug application (NDA) with the FDA seeking approval to sell the drug for a particular use. The FDA will review the NDA and often will hold a public hearing where an independent advisory committee of expert advisors asks additional questions regarding the drug. This committee makes a recommendation to the FDA that is not binding on the FDA but is generally followed by the FDA. If the FDA agrees that the compound has a required level of safety and effectiveness for a particular use, it will allow us to sell the drug in the U.S. for that use. It is not unusual, however, for the FDA to reject an application because it believes that the drug is not safe enough or effective enough or because it does not believe that the data submitted is reliable or conclusive.

    At any point in this process, the development of a drug could be stopped for a number of reasons including safety concerns and lack of treatment benefit. We cannot be certain that any clinical trials that we are conducting, including those for Viread and emtricitabine for HIV infection and Hepsera for chronic hepatitis B, or any that we conduct in the future, will be completed successfully or within any specified time period. We may choose, or the FDA may require us to delay or suspend our clinical trials at any time if it appears that the patients are being exposed to an unacceptable health risk or if the drug candidate does not appear to have sufficient treatment benefit.

    The FDA may also require us to complete additional testing, provide additional data or information, improve our manufacturing processes, procedures or facilities or require extensive post-marketing testing and surveillance to monitor the safety or benefits of our product candidates if

    21



    they determine that our new drug application does not contain adequate evidence of the safety and benefits of the drug. In addition, even if the FDA approves a drug, it could limit the uses of the drug. Approvals can also be withdrawn if the FDA does not believe that we are complying with regulatory standards or if problems are uncovered or occur after approval.


    In addition to obtaining FDA approval for each drug, the manufacturing facilities for any drug we sell, including those of companies who manufacture our drugs for us as well as our own, must be approved by the FDA and are subject to periodic inspections by the FDA. Foreign establishments that manufacture products to be sold in the U.S. must also be approved by the FDA and are subject to periodic regulatory inspection. Manufacturing facilities located in California, including our San Dimas facility and Foster City facility, also must be licensed by the State of California in compliance with local regulatory requirements.

    Drugs that treat serious or life-threatening diseases and conditions that are not adequately addressed by existing drugs may be designated as fast track products by the FDA and may be eligible for priority six month review and accelerated approval, as was the case for Viread. Drugs receiving accelerated approval must be monitored in post-marketing clinical trials in order to confirm the safety and benefits of the drug.

    We are also subject to other federal, state and local regulations regarding workplace safety and protection of the environment. We use hazardous materials, chemicals, viruses and various radioactive compounds in our research and development activities and cannot eliminate the risk of accidental contamination or injury from these materials. Any misuse or accidents involving these materials could lead to significant litigation, fines and penalties.

    Drugs are also subject to extensive regulation outside of the U.S. In the European Union, there is a centralized approval procedure that authorizes marketing of a product in all countries in the European Union (which includes most major countries in Europe). If this procedure is not used, under a decentralized system an approval in one country of the European Union can be used to obtain approval in another country of the European Union under a simplified application process. After approval under the centralized procedure, pricing and reimbursement approvals are also required in most countries. Vistide, Viread, Hepsera and VireadEmtriva were approved by the European Union under the centralized procedure. Viread as an HIV drug was reviewed for accelerated approval in the European Union. Hepsera received a traditional review, as has emtricitabine.did Emtriva.

    Pricing and Reimbursement

    Insurance companies, health maintenance organizations (HMOs), other third-party payors and some governments seek to limit the amount we can charge for our drugs. For example, in certain foreign markets, pricing negotiations are often required to obtain approval of a product, and in the U.S. there have been, and we expect that there will continue to be, a number of federal and state proposals to implement drug price control. In addition, managed care organizations are becoming more common in the U.S. and will continue to seek lower drug prices. The announcement of these proposals or efforts can cause our stock price to lower,decrease, and if these proposals are adopted, our revenues could decrease.

    Our ability to sell our drugs also depends on the availability of reimbursement from governments and private insurance companies. These governments and insurance companies often demand rebates or predetermined discounts from list prices. We expect that products we are developing, particularly for AIDS indications, will be subject to reimbursement issues. We cannot be certain that any of our other products that obtain regulatory approval will be reimbursed by these government and insurance companies.

    22



    Regulatory approval of prices is generally required in most foreign countries. In particular, certain countries will condition their approval of a product on the agreement of the seller not to sell that product for more than a certain price in that country and in the past have required price reductions after or in connection with product approval. We cannot be certain that regulatory authorities in the future will not establish lower prices or that any regulatory action reducing the price of our products in any one country will not have the practical effect of requiring us to reduce our prices in other countries. Some European governments, notably Germany and Italy, have implemented, or are considering, legislation that would require pharmaceutical companies to sell their products subject to reimbursement at a mandatory


    discount. Such mandatory discounts would reduce the revenue we receive from our drug sales. In certain developing countries that are significantly affected by HIV and AIDS, parallel importing and generic competition may occur and adversely affect revenues from sales of or market share of Viread.

    Management Changes

            In March 2002, we announced that John F. Milligan, PhD, was promoted to Senior Vice President and Chief Financial Officer, reporting directly to the CEO. This was part of a restructuring in which we combined responsibility for the corporate functions that support the strategic, financial, communications and technological planning into a broadened senior management role. As such, the Corporate Development, Finance, Corporate Communications and Information Technology groups have been centralized under the leadership of Dr. Milligan. In addition, we announced at that time the completion of other organization changes, including the alignment of the manufacturing group in San Dimas with other operational areas, reporting to Mark L. Perry, Executive Vice President, Operations, and establishing a Paris, France headquarters for our European operations.

    Employees

    As of February 28, 2003,27, 2004, we had approximately 1,2501,425 full-time employees. We believe that we have good relations with our employees.

    Website

    Our website address is www.gilead.com.

    RISK FACTORS THAT AFFECT GILEAD

    In evaluating our business, you should carefully consider the following risks in addition to the other information in this report. Any of the following risks could materially and adversely affect our business, operating results and financial condition.

    Substantially all of our revenues are derived from sales of two products. If Viread does notwe are unable to maintain or increase its market acceptance,continue growing sales of Viread or to maintain sales of AmBisome our results of operations will suffer.may be adversely affected.

Viread product sales for the year ended December 31, 2003 were $566.5 million, or are in advanced stages of clinical development, including 20 products currently sold in the U.S. Among the companies that are significant competitors in the HIV/AIDS market are GSK, Bristol-Myers Squibb, Roche, Pfizer, Merck, Boehringer-Ingelheim and Abbott Laboratories.

            All65%, of our competitorstotal revenues and mostAmBisome product sales and royalties for the year ended December 31, 2003 were $210.9 million, or 24% of our potential competitorstotal revenues. We may not be able to maintain the growth rate of Viread or the current sales level of AmBisome for the reasons stated in this risk factor section and, in particular, the following reasons:

    ·       We face significant competition from businesses that have substantially greater resources than we do. Those resources include greater experienceFor example, in promoting2003, we experienced declining sales volumes for AmBisome due in part to the introduction of new European competitors. On a volume basis, AmBisome sales decreased by 5% in Europe in 2003 compared to 2002.

    ·       As Viread and marketing HIVAmBisome are used over a longer period of time and additional studies are conducted, new issues with respect to safety, resistance and interactions with other drugs superiormay arise which could cause us to provide additional warnings on our labels, narrow our approved indications or halt sales of a product, development capabilitieseach of which could reduce our revenues.

    ·       As a product matures, private insurers and financial, scientific, manufacturing, marketing,government reimbursers may reduce the amount they will reimburse patients for these products, which will increase pressure on us to reduce prices. For example, in 2003, authorities in Germany and Italy reduced the amount of reimbursement they will provide for patients using Viread and we expect similar reductions in France in 2004.

    managerialIf we fail to commercialize new products or expand the indications for existing products, our prospects for future revenues and human resources.stock price may be adversely affected.

    If we do not introduce new products or increase revenues from our existing products, we may not be able to grow our revenues. In order to expand our products, we have begun marketing Hepsera for Vireadthe treatment of chronic hepatitis B and Emtriva for the treatment of HIV in the United States and in the European Union. In addition, we are developing a co-formulation of tenofovir with emtricitabine. Failure to continue its success,achieve any of these objectives when expected, or at all, may have a material adverse effect on our business and results of operations. We may not be able to achieve these objectives for the following reasons:

    ·       Hepsera is a new drug and faces a competitive marketplace in which we willhave less experience than established competitors. For example, Hepsera primarily competes with lamivudine in the United States and with interferon-alfa 2b in the European hepatitis B market. Hepsera’s primary advantage over lamivudine is that patients have so far been less likely to develop resistance to Hepsera than they have to maintainlamivudine. However, lamivudine has been on the market longer than Hepsera and expand its position inlamivudine’s resistance problems did not surface until after the marketplace against these competitors' drugs.

            Viread's market penetration may be limited, particularly for use in treatment-naïve patients, given that most of our data, and the data supporting our marketing approvals, reflects use of Viread in a treatment-experienced patient population. Although we have obtained data about the safety and efficacy of Viread in treatment-naïve patients, regulatory authoritiesproduct was marketed. Hepsera may not allow uscontinue to include this data inshow superior resistance properties to lamivudine. Hepsera’s primary advantages


    over interferon-alfa 2b are greater safety, tolerability and oral dosing. Newer versions of interferon (pegylated-interferon) are under development and may prove to be safer, more tolerable and offer once-weekly injectable dosing. Marketing a treatment for hepatitis B is also difficult since many infected individuals are not diagnosed and there is not a consensus among physicians as to the labeling for Viread. appropriate methods of treatment.

    ·       A physical combination of emtricitabine with tenofovir may not be technically feasible or cost-effective. In addition, we may not be able to develop a chemistry, manufacturing and bioequivalence package that shows the co-formulated tablet gives the same exposure to tenofovir and emtricitabine as the two drugs given individually that will support regulatory approval. We have not completed stability studies necessary to support approval of a co-formulation of tenofovir and emtricitabine.

    If we fail to increase our marketing efforts are unsuccessfulsales of Hepsera or if we cannot include information about Viread's use in treatment-naïve patients in Viread's labeling data,do not obtain regulatory approval and successfully market a co-formulation of emtricitabine and tenofovir, we may not be unsuccessful in convincing physiciansable to prescribe Viread to their treatment-naïve patients,increase revenues and some government reimbursers and private insurance companies may not pay for Viread for prescribed patients who have not had prior HIV therapy. If Viread does not maintain or increase its market acceptance,expand our results of operations will suffer.

    Any significant reduction in Viread, AmBisome or Hepsera sales would significantly reduce our operating income and could require us to scale back our manufacturing operations and reduce our sales force.

            Viread product sales for the years ended December 31, 2001 and 2002, were $15.6 million, or 7% and $225.8 million, or 48%, of our total revenues, respectively. We expect that product sales of Viread will constitute a substantial part of our total revenues for the foreseeable future.

            AmBisome sales for the years ended December 31, 2000, 2001 and 2002 were $141.1 million, or 72%, $164.5 million, or 70% and $185.7 million, or 40% of our total revenues. We expect that revenues from sales of AmBisome will continue to provide a material portion of our total product revenues.

            Hepsera product sales, which began in September 2002, for the year ended December 31, 2002, were approximately $4.2 million, or 1% of our total revenues. We expect that product sales of Hepsera will constitute a substantial part of our total revenues in the foreseeable future.

            Accordingly, for the foreseeable future, we expect that we will continue to rely heavily on sales of Viread, AmBisome and Hepsera to support our existing manufacturing and sales infrastructure and to provide operating income to fund a significant portion of our administrative and research and development expenditures. Anyefforts.

    If significant reduction in sales of Viread, AmBisome or Hepsera, whether as a result of the introduction of competitive products or otherwise, would hurt our business, and we would have to scale back our manufacturing operations and reduce our sales force.

    If safety issues arise for our marketed products, this could significantly reduce or limit our sales andmay decline, which would adversely affect our results of operations.

    The data that support the marketing approvals for our products, including Viread, AmBisome, Hepsera and Hepsera,Emtriva and that form the basis for the safety warnings in our product labels, waswere obtained in controlled clinical trials of limited duration, and, in the case of Viread, from limited post-approval use. Following approval, these products are and will be used over longer periods of time in many patients taking numerous other medicines, who have underlying health problems and who will not be monitored for dosing compliance. If new safety issues are reported in post-marketing use and we cannot rule out the contributory role of our products, we may be required to provide additional warnings on our labels or narrow our approved indications, each of which could reduce the market acceptance of these products. For example, while we did not observe kidney toxicity in our clinical trials of Viread, kidney toxicity has been reported with post-approval use of Viread and the Viread label has been updated to include this warning. If serious safety issues with our marketed products were to arise, we could face potential product liability claims and sales of these products could be halted by us or by regulatory authorities. Similarly, inIn 1999, we discontinued development of adefovir dipivoxil 60 mg for treatment of HIV infection due to safety and benefit concerns about kidney toxicity arising from our studies. Double-blind, placebo-

    24



    controlled studies of adefovir dipivoxil 10 mg have demonstrated safety and efficacy in the treatment of patients with chronic hepatitis B. Studies have shown that adefovir dipivoxil is significantly more effective against HBV than against HIV, allowing us to use a lower dose of 10 mg of adefovir dipivoxil in Hepsera than was used for treatment of HIV infection. The 10 mg dose of adefovir dipivoxil used in Hepsera has not been associated with significant kidney toxicity in our clinical trials to date, other than in patients who have pre-existing kidney problems or who are taking drugs known to cause kidney toxicity. The FDA has granted marketing approval for Hepsera, but we cannot be certain that the results from these Phase 3 clinical studies of Hepsera will demonstrate, to the satisfaction of other regulatory agencies, includingHowever, kidney toxicity may develop in the European Union, that Hepsera can be a safe and effective treatment for chronic hepatitis B.

    Hepsera is a new drug, and it may not gain significant market acceptance.

            Hepsera is a new drug and faces a competitive marketplace. There are currently two drugs sold in the U.S. for treatment of chronicbroader hepatitis B and other potential drugs are in late stages of clinical development. Our competitors and most of our potential competitors have substantially greater resources than we do. Those resources include greater experience in promoting and marketing pharmaceuticals (including HBV drugs), superior product development capabilities and greater financial, scientific, manufacturing, marketing, managerial and human resources. In order for Hepsera to be successful, we will have to establish it in the marketplace against these competitors' drugs. It is too early to determine if Hepsera will achieve significant market acceptance.patient population.

            There is no well-developed market or generally accepted treatment strategy for hepatitis B. We have never marketed or sold a drug for treatment of chronic hepatitis B before and might not be successful in doing so and may not be able to develop this therapeutic market effectively. Long term use of Hepsera may reveal safety issues or the development of resistance to Hepsera in patients. If our marketing efforts are unsuccessful, or if Hepsera turns out to have safety or resistance issues, we may be unsuccessful in convincing physicians to prescribe Hepsera to their patients, and some government reimbursers and private insurance companies may not pay for Hepsera. If Hepsera does not gain significant market acceptance, our expected future results of operations will suffer.

    Fiscal year 2002 was our first full year of operating profitability, and we may not be able to maintain profitability on a sustainable basis.

            Until 2002, we had never been profitable on an operating basis for a full year, and we may not continue to be profitable in the future. We expect the merger with Triangle will reduce our earnings in 2003, have no effect on earnings in 2004, and increase our earnings in 2005, although we cannot be certain our estimates are correct. At December 31, 2002, our accumulated deficit was approximately $381.6 million. Our losses have resulted principally from expenses associated with our research and development programs and, to a lesser extent, from sales, general and administrative expenses. Our operating results may be adversely affected by reduced sales of our products, increased marketing or development expenses, acquisitions of products or companies, such as Triangle, that are unprofitable at the time of acquisition or as a result of the other risks described in this report.

    We develop drugs to treat HIV infection and AIDS and related conditions, and therefore changes in the regulatory and commercial environment for HIV infection and AIDS therapies could harm our business.

            Several of our products and products in development address HIV infection and AIDS or related conditions. These products include Viread and emtricitabine for HIV infection and AIDS, Vistide for CMV retinitis and DaunoXome for HIV-associated Kaposi's sarcoma. We develop those products based upon current policy and the current marketplace for HIV infection and AIDS therapies, as well as our prediction of future policy and the future marketplace for these therapies. Our business is subject to

    25



    substantial risk because these policies and markets change quickly and unpredictably and in ways that could impair our ability to maintain regulatory approval and commercial acceptance of these products.

    Our operations depend on compliance with complex FDA and comparable international regulations. Failure to obtain broad approvals on a timely basis or to achieve continued compliance could delay commercialization of our products.

    The products that we develop must be approved for marketing and sale by regulatory authorities and will be subject to extensive regulation by the FDA and comparable regulatory agencies in other countries. We are continuing clinical trials for AmBisome, Viread, Hepsera and HepseraEmtriva for currently approved and additional uses. We anticipate that we will conduct a variety of clinical trials and file for marketing approval ofin additional countries and for additional products over the next several years. These products may fail to receive marketing approval on a timely basis, or at all. We cannot be certain that HepseraAlso, our current filing strategy for a co-formulation of tenofovir and emtricitabine is based on data from completed studies: if the FDA requires additional pivotal studies for a combination product our regulatory filing will be approved bydelayed. Regulatory authorities outside of the U.S. and the European Union or regulatory authorities in other countries other than the U.S., or whether Hepsera will receive marketing approvals in such countries with significant limitations placed on its use. We cannot be certain thatmay not approve emtricitabine will be approved in the U.S. or the European Union or whether marketing approvals willfor treatment of HIV because it does not have significant limitations on its use.sufficient efficacy advantages over a currently marketed lamivudine product. We also cannot be certain that we willmay not be able to obtain the regulatory approvals necessary to expand our commercial efforts into new markets. These failures, delays


    or limitations, as well as other regulatory changes, actions and recalls, could delay commercialization of any products and adversely affect our results of operations.

    In addition, even after our products are marketed the products and their manufacturershow we sell these products are subject to continualextensive regulation and review. Later discovery of previously unknown problems with our products or problems with our own manufacturing or the production by third-party manufacturerspromotional activities may result in restrictions on our products or the manufacture of our products, including withdrawal of the products from the market. For example, on August 7, 2003, the FDA issued a written warning concerning our promotional activities of Viread. If we fail to comply with applicable regulatory requirements, we could be subject to penalties including fines, suspensions of regulatory approvals, product recalls, seizure of products and criminal prosecution. In addition, we have been named in a multi-party lawsuit alleging that we inflated the reimbursement rates under the Medicaid Program of certain pharmaceuticals we manufacture.

    Results of clinical trials are uncertain and may not support regulatory approvalcontinued development of a product pipeline, which would adversely affect our products.prospects for future revenue growth.

    We are required to demonstrate the safety and effectiveness of products we develop in each intended use through extensive preclinical studies and clinical trials in order to obtain regulatory approval of these products.trials. The results from preclinical and early clinical studies do not always accurately predict results in later, large-scale clinical trials for several reasons, including:

      preliminary results may not be indicative of effectiveness;

      further clinical trials may not achieve the desired result; and

      further clinical trials may reveal unduly harmful side effects or may show the drugs to be less effective than other drugs or delivery systems for the desired indications.

    trials. Even successfully completed large-scale clinical trials may not result in marketable products for several reasons, including:

      the potential products are not shown to be safe and effective;

      regulatory authorities disagree with the results or design of our studies and trials; or

      the potential products are too difficult to develop into commercially viable products.

    A number of companies in our industry have suffered setbacks in advanced clinical trials despite promising results in earlier trials. For example, in 1999 the FDA denied approval of adefovir dipivoxil (60 mg), a drug developed by Gilead for the treatment of HIV, based on concerns regarding kidney toxicity. We may in the future seek clinical development of similar compounds that also have the potential for kidney toxicity or other adverse effects. If any of our products under development fail to achieve their primary endpoint in clinical trials or if safety issues arise, commercialization of that drug candidate could be delayed or halted.

    Manufacturing problems could delay product shipments and regulatory approvals, which may adversely affect our results of operations.

    We depend on third parties to perform manufacturing activities effectively and on a timely basis. If these third parties fail to perform as required, this could impair our ability to deliver our products on a timely basis or cause delays in our clinical trials and applications for regulatory approval, and these events could harm our competitive position. The manufacturing process for pharmaceutical products is highly regulated, and regulators may shut down manufacturing facilities that they believe do not comply with regulations. The FDA’s current Good Manufacturing Practices are extensive regulations governing manufacturing processes, stability testing, record-keeping and quality standards. In addition, our manufacturing operations are subject to routine inspections by regulatory agencies and similar regulations are in effect in other countries.

    For Viread, Hepsera, Vistide and Emtriva, we rely on third parties for the manufacture of bulk drug substance and final drug product for clinical and commercial purposes. In addition, Roche is responsible for manufacturing Tamiflu. These third-party manufacturers may develop problems over which we have no control and these problems may adversely affect our business. For example, in January 2002, Roche announced that due to production problems the liquid suspension form of Tamiflu approved for treatment of children as young as one year old was not available. In Japan, where the 2002-2003 flu season was particularly severe, Roche’s sublicensee, Chugai Corporation, was unable to meet heightened demand satisfactorily. In January 2003, Chugai issued a press release attributing this failure, in part, to manufacturing problems. These problems in Japan have reduced the net sales and our royalty from Roche.

    We manufacture AmBisome at our facilities in San Dimas, California. These are our only formulation and manufacturing facilities in the U.S. We own a manufacturing facility in Ireland that performs certain


    quality control testing, labeling and packaging. In addition, we use third parties as alternate contract suppliers to fill and freeze dry certain batches of product. In the end,event of a natural disaster, including an earthquake, equipment failure, strike or other difficulty, we may be unable to replace this manufacturing capacity in a timely manner and would be unable to manufacture AmBisome to meet market needs.

    We may not be able to obtain materials necessary to manufacture our products, which could limit our ability to generate revenues.

    Many of the materials that we utilize in our operations are made at only one facility. For example, we depend on single suppliers for high quality amphotericin B, distearoylphosphatidylcholine and high quality cholesterol, each of which is used in the manufacture of one or more of our liposomal products. Because the suppliers of key components and materials must be named in the new drug application filed with the FDA for a product, significant delays can occur if the qualification of a new supplier is required. If supplies from our suppliers were interrupted for any reason, we may be unable to ship Viread, AmBisome, Hepsera, Emtriva or Vistide, or to supply any of our products in development for clinical trials.

    We may need to develop additional marketable products.manufacturing capacity for our existing and future products, which will increase our expenses.

    26



    DelaysWe have evaluated in enrolling patients or developing suitable protocols forthe past, and continue to evaluate, the feasibility of acquiring manufacturing capabilities to support the production of our products, principally Viread and Emtriva. These facilities may be required to increase production capacities in order to support clinical trials could increase costs and delay regulatory approvals.

            The rate of completion of our clinical trials will depend on the rate of patient enrollment. There will be substantial competition to enroll patients in clinical trialsproduce such products for drugs in development. This competition has delayed our clinical trialscommercial sale at an acceptable cost. We have not manufactured these products in the past. In addition, recent improvements in existing drug therapy, particularly for HIVDeveloping these technological capabilities and hepatitis B, may make it more difficult for usbuilding or purchasing a facility will increase our expenses with no guarantee that we will be able to enroll patientsrecover our investment in our manufacturing capabilities.

    We depend on relationships with other companies for sales and marketing performance and revenues. Failure to maintain these relationships would negatively impact our business.

    We rely on a number of significant collaborative relationships with major pharmaceutical companies for our sales and marketing performance. These include collaborations with Fujisawa and Sumitomo for AmBisome, GSK for Hepsera, Roche for Tamiflu, Pfizer for Vistide and Japan Tobacco for Viread and Emtriva. In certain countries, we rely on international distributors for sales of AmBisome, Viread and Emtriva and in some European countries, we intend to rely only on international distributors for sales of Hepsera. Some of these relationships also involve the clinical trials asdevelopment of these products by our partners. Reliance on collaborative relationships poses a number of risks, including:

    ·       we will not be able to control whether our corporate partners will devote sufficient resources to our programs or products;

    ·       disputes may arise in the patient populationfuture with respect to the ownership of rights to technology developed with corporate partners;

    ·       disagreements with corporate partners could lead to delays in or termination of the research, development or commercialization of product candidates, or result in litigation or arbitration;

    ·       contracts with our corporate partners may fail to provide significant protection or may fail to be effectively enforced if one of these partners fails to perform;

    ·       corporate partners have considerable discretion in electing whether to pursue the development of any additional products and may pursue alternative technologies or products either on their own or in collaboration with our competitors;


    ·       corporate partners with marketing rights may choose to enrolldevote fewer resources to the marketing of our products than they do to products of their own development; and

    ·       our distributors and corporate partners may be unable to pay us

    Given these risks, there is a great deal of uncertainty regarding the success of our current and future collaborative efforts. If these efforts fail, our product development or commercialization of new products could be delayed or revenue from existing products, including Viread, Emtriva, Hepsera, AmBisome and Tamiflu, could decline.

    Under our April 2002 licensing agreement with GSK, we gave GSK the right to control clinical and regulatory development and commercialization of Hepsera in territories in Asia, Africa and Latin America. These include major markets for Hepsera, such as China, Japan, Taiwan and Korea. The success of Hepsera in these territories will depend almost entirely on the efforts of GSK. In this regard, GSK promotes Epivir—HBV, a product that competes with Hepsera. Consequently, GSK’s marketing strategy for Hepsera may be influenced by its promotion of Epivir—HBV. We receive royalties from GSK equal to a percentage of net sales made by GSK. If GSK fails to devote sufficient resources to, or does not succeed in developing or commercializing Hepsera in its territories, our potential revenues from sales of Hepsera may be substantially reduced.

It is difficult to accurately predict or control the amount or timing of these expenses from quarter to quarter. Uneven and unexpected spending on these programs may cause our operating results to fluctuate from quarter to quarter. In addition, feedbacka substantial portion of our sales activity in the United States is conducted with three distributors, Amerisource Bergen Corp., McKesson Corp. and Cardinal Health, Inc. Inventory levels held by these and other wholesalers may fluctuate significantly which could cause our sales to them and as a result, our operating results, to fluctuate unexpectedly from regulatory authoritiesquarter to quarter. For example, based on our review of NDC prescription trends, IMS inventory data and actual Viread sales, we believe, in the quarter ended June 30, 2003, wholesalers built up inventory levels by an estimated 1.2 months. We believe this inventory build-up was followed by an equivalent or results from earlier stage clinical studies might require modifications or delays in later stage clinical trials. These types of delays can result in increased development costs and delayed regulatory approvals.possibly greater inventory reduction during the quarter ended September 30, 2003.

    Approximately half of our product sales occur outside the U.S., and currency fluctuations may impaircause our financial results.earnings to fluctuate, which could adversely affect our stock price.

    A significant percentage of our product sales are denominated in foreign currencies. Increases in the value of the U.S. dollar against these foreign currencies in the past have reduced, and in the future may reduce, our U.S. dollar equivalent sales and negatively impact our financial condition and results of operations. Effective January 2002, we began toWe use foreign currency forward contracts to hedge a percentage of our forecasted international sales, primarily those denominated in the Euro currency. We also hedge a portion of our accounts receivable balances denominated in foreign currencies, which reduces but does not eliminate our exposure to currency fluctuations between the date a sale is recorded and the date that cash is collected. Additionally, to mitigate the impact of currency rate fluctuations on our cash outflows for certain foreign currency-denominated raw materials purchases, we enter into foreign exchange forward contracts to hedge our foreign currency-denominated accounts payable. Although we use forward contracts to reduce the impact of foreign currency fluctuations on our future results, we cannot be certain that these efforts willmay not be successful and any such fluctuations could adversely affect our results of operations.


    We face credit risks from our international accounts receivable.European customers that may adversely affect our results of operations.

    We are particularly subject to credit risk from our accounts receivable related to European product sales.customers. Our European product sales to government owned or supported customers in Greece, Spain, Portugal, and Italy are subject to significant payment delays due to government funding and reimbursement practices. Our accounts receivable from government owned or supported customers in these countries totaled $148.4 million as of December 31, 2003. If significant changes were to occur in the reimbursement practices of European governments or if government funding becomes unavailable, we may not be able to collect on amounts due to us from these customers and our financial position and results of operations would be adversely affected.

    Product development expenses can cause our operating expenses to fluctuate from quarter to quarter.

            The clinical trials required for regulatory approval of our products are extremely expensive. It is difficult to accurately predict or control the amount or timing of these expenses from quarter to quarter. Uneven and unexpected activity in these programs causes our operating results to fluctuate from quarter to quarter.

    27



    We depend on relationships with other companies for sales and marketing performance and revenues. Failure to maintain these relationships would negatively impact our business.

            We rely on a number of significant collaborative relationships with major pharmaceutical companies for our sales and marketing performance. These include collaborations with Fujisawa and Sumitomo for AmBisome, GSK for Hepsera, Roche for Tamiflu and Pharmacia for Vistide. In certain countries, we only rely on international distributors for sales of AmBisome and Viread and in some European countries, we intend to rely only on international distributors for sales of Hepsera. Some of these relationships also involve the clinical development of products by our partners. Reliance on collaborative relationships poses a number of risks, including:

      we will not be able to control whether our corporate partners will devote sufficient resources to our programs or products;

      disputes may arise in the future with respect to the ownership of rights to technology developed with corporate partners;

      disagreements with corporate partners could lead to delays in or termination of the research, development or commercialization of product candidates, or result in litigation or arbitration;

      contracts with our corporate partners may fail to provide significant protection or may fail to be effectively enforced if one of these partners fails to perform;

      corporate partners have considerable discretion in electing whether to pursue the development of any additional products and may pursue alternative technologies or products either on their own or in collaboration with our competitors;

      corporate partners with marketing rights may choose to devote fewer resources to the marketing of our products than they do to products of their own development;

      our distributors and corporate partners may be unable to pay us.

            Given these risks, there is a great deal of uncertainty regarding the success of our current and future collaborative efforts. If these efforts fail, our product development or commercialization of new products could be delayed or revenue from existing products, including Viread, Hepsera, AmBisome and Tamiflu, could decline. In January 2002, Roche announced that due to production problems the liquid suspension form of Tamiflu approved for treatment of children as young as one year old was not available; however, the liquid suspension form of Tamiflu was returned to market in time for the 2002-2003 flu season. These production issues did not affect availability of the tablet form of Tamiflu for adults and adolescents 13 years and older. In Japan, where the 2002-2003 flu season has been particularly severe, Roche's sublicensee, Chugai Corporation, has been unable to meet heightened demand satisfactorily. In January 2003, Chugai issued a press release attributing this failure, in part, to manufacturing problems. These problems in Japan have reduced the net sales on which our royalty with Roche is based.

            Under our April 2002 licensing agreement with GSK, we gave GSK the right to control clinical and regulatory development and commercialization of Hepsera in territories including Asia, Africa and Latin America. These include major markets for Hepsera, such as China, Japan, Taiwan and Korea. The success of Hepsera in these territories will depend almost entirely on the efforts of GSK. We receive royalties from GSK equal to a percentage of net sales made by GSK. If GSK fails to devote sufficient resources to, or does not succeed in developing or commercializing Hepsera in its territories, our potential revenues from sales of Hepsera may be substantially reduced.

    Our existing products and products under development may not be accepted by physicians, insurers and patients.

            The ability of our products to achieve and sustain market acceptance in countries where they are approved for marketing will depend on the scope of regulatory approvals and whether or not government authorities and managed care organizations will adequately reimburse patients who use these products.

            In addition, we need to convince the medical and patient advocacy community of:

      the effectiveness of these products in treating disease;

      the safety of these products when administered to patients; and

      the advantages of these products over competitive products.

            Physicians, patients, patient advocates, payors and the medical community in general may not accept or use any products that we may develop. If our products are not accepted, our results of operations will suffer.

            Many other companies are targeting the same diseases and conditions as we are. Competitive products from other companies could significantly reduce the market acceptance of our products.

            Our products and development programs target a number of diseases and conditions, including viral infections and fungal infections. There are many commercially available products for these diseases. Certain of these products are well-established therapies and have generated substantial sales. In addition, a large number of companies and institutions are conducting well-funded research and development activities directed at developing treatments for these diseases. Products currently on the market and those under development by our competitors could make our technology and products obsolete or noncompetitive. We expect that competition for the treatment of these diseases will increase in the future as new products enter the market and advanced technologies become available. We will also be competing to license or acquire technology from other companies.

    Our plan to supply Viread at our cost to certain developing countries will reduce Viread's gross profit marginmay expose us to liability that would have a material adverse affect on our results of operations and could give rise to unforeseen liabilities.financial condition.

    We are launching a distribution program pursuant to which we will supply Viread at our cost to all countries in Africa and to the 15 other countries designated "Least“Least Developed Countries"Countries” by the United Nations. Because we will receive no profit from the Viread we supply through this program, it will reduce the Viread product's gross profit margin. The amount of that reduction will depend upon the volume of Viread that flows through this program, which we cannot predict with any certainty. Additionally, supply and distribution of drugs in a resource-poor environment is a complicated undertaking. As this program develops, we could face unforeseen challenges and risks, which could give rise to unforeseen liabilities. For example, patients in less developed countries using Viread may not be as closely supervised by a doctor as they would be in more developed nations. Accordingly, there may be an increased likelihood of Viread-related complications going undetected or untreated, which could result in significant liability to Gilead.

    Our product revenues could be reduced by imports from countries where our products are available at lower prices.

    Prices for our products are based on local market economics and competition and sometimes differ from country to country. Our sales in countries with relatively higher prices may be reduced if products can be imported into those countries from lower price markets. There have been cases in which pharmaceutical products were sold at steeply discounted prices in the developing world and then re-exported to European countries, where they could be re-sold at much higher prices. If this happens with our products, particularly Viread, which we have agreed to provide at our cost to all countries in Africa and to the 15 other countries designated “Least Developed Countries” by the United Nations, our revenues would be adversely affected.

    In addition, in the European Union, we are required to permit cross border sales. This allows buyers in countries where government-approved prices for our products are relatively high to purchase our products legally from countries where they must be sold at lower prices. Additionally, some U.S. consumers have been able to purchase products, including HIV medicines, from Internet pharmacies in other countries at substantial discounts. Such cross-border sales could adversely affect our revenues.

    In some countries, we may be required to grant compulsory licenses for our HIV products or face generic competition for our HIV products.

    In a number of developing countries, government officials and other groups have suggested that pharmaceutical companies should make drugs for HIV infection available at a low cost. In some cases, governmental authorities have indicated that where pharmaceutical companies do not make their HIV drugs available at a low cost, their patents might not be enforceable to prevent generic competition. Some major pharmaceutical companies have greatly reduced prices for HIV drugs in certain developing countries. If certain countries do not permit enforcement of our patents, sales of our products in those countries could be reduced by generic competition. Alternatively, governments in those countries could require that we grant compulsory licenses to allow competitors to manufacture and sell their own versions of our products in those countries, thereby reducing our sales, or we could respond to governmental concerns by reducing prices for our products. In addition to reducing our sales, compulsory licenses may


    increase the risk of counterfeiting as we would no longer have control over manufacturing and distribution in those markets. In addition, countries such as Canada are considering amending their patent laws to permit the export of otherwise patented products to countries in the developing world. In all of these situations, our results of operations could be adversely affected.

    Our existing products are subject to reimbursement from government agencies and other third parties. Pharmaceutical pricing and reimbursement pressures may reduce profitability.

    Successful commercialization of our products depends, in part, on the availability of governmental and third party payor reimbursement for the cost of such products and related treatments. Government health administration authorities, private health insurers and other organizations generally provide reimbursement. Government authorities and third-party payors increasingly are challenging the price of medical products and services, particularly for innovative new products and therapies. This has resulted in lower average sales prices. For example, a majority of our sales of AmBisome Vistide and DaunoXome,Vistide, and a significant percentage of our sales of Viread and Hepsera, are subject to reimbursement by government agencies, resulting in significant discounts from list price and rebate

    29



    obligations. Our business may be adversely affected by an increase in U.S. or international pricing pressures. These pressures can arise from rules and practices of managed care groups, judicial decisions and governmental laws and regulations related to Medicare, Medicaid and health care reform, pharmaceutical reimbursement and pricing in general. In the U.S. in recent years, new legislation has been proposed at the federal and state levels that would effect major changes in the health care system, either nationally or at the state level. These proposals have included prescription drug benefit proposals for Medicare beneficiaries introduced inrecently passed by Congress. Although there has been no U.S. federal reform legislation,Additionally, some states have enacted health care reform legislation. Further federal and state developments are possible. Although we cannot predict the exact nature of legislative health care reforms, if any, ourOur results of operations could be adversely affected by suchfuture health care reforms. In Europe, the success of Hepsera, (if approved for sale), Tamiflu, Emtriva and Viread will also depend largely on obtaining and maintaining government reimbursement in Europe because in many European countries, including the United Kingdom and France, patients are reluctant to pay for prescription drugs out of their own pocket. We also expect that the success of our products in development, particularly in Europe, will depend on the ability to obtain reimbursement. Even if reimbursement is available, reimbursement policies may adversely affect our ability to sell our products on a profitable basis.

    In addition, in many international markets, governments control the prices of prescription pharmaceuticals. In these markets, once regulatory marketing approval is received, pricing negotiations with governmental authorities can take another six to twelve months or longer. Some foreign governments have passed, or are considering, legislation to require us to sell our products subject to reimbursement at a mandatory discount. Sales of competing products, attempts to gain market share or introductory pricing programs of our competitors could also require us to lower our prices in these countries, which could adversely affect our results of operations. Some foreign governments have passed, or are considering, legislation to require us to sell our products subject to reimbursement at a mandatory discount.

    Our product revenues could be reduced by imports from countries where our products are available at lower prices.

            Our sales in countries with relatively higher prices may be reduced if products can be imported into those countries from lower price markets. There have been cases in which pharmaceutical products were sold at steeply discounted prices in the developing world and then re-exported to European countries, where they could be re-sold at much higher prices. If this happens with our products, particularly Viread, which we have agreed to provide at our cost to all countries in Africa and to the 15 other countries designated "Least Developed Countries" by the United Nations, our revenues would be adversely affected.

            In addition, in the European Union, we are required to permit cross border sales. This allows buyers in countries where government-approved prices for our products are relatively high to purchase our products legally from countries where they must be sold at lower prices. Such cross-border sales adversely affect our revenues.

    We may not be able to obtain effective patents to protect our technologies from use by competitors, and patents of other companies could require us to stop using or pay for the use of required technology.

    Our success will depend to a significant degree on our ability to:

      ·obtain patents and licenses to patent rights;

      ·preserve trade secrets; and

      ·operate without infringing on the proprietary rights of others.

    30


      We have rights to U.S. and foreign issued patents and have filed and will continue to file patent applications in the U.S. and abroad relating to our technologies. There is a risk, however, that patents may not issue from any of these applications or that the patents will not be sufficient to protect our technology.


      Patent applications are confidential for at least some period of time, sometimes in the U.S. until a patent issues. As a result, we may not know if our competitors filed patent applications for technology covered by our pending applications. We also cannot be certain thatapplications or if we were the first to invent the technology that is the subject of our patent applications. Competitors may have filed patent applications or received patents and may obtain additional patents and proprietary rights that block or compete with our patents.

      We do not have patent filings in China or certain other Asian countries covering all forms of adefovir dipivoxil, the active ingredient in Hepsera, although we do have applications pending in various Asian countries that relate to various forms and formulations of adefovir dipivoxil. Asia is a major market for therapies for hepatitis B, the indication for which Hepsera has been developed. We may obtain patents for certain products many years before marketing approval is obtained for those products. Because patents have a limited life, which may begin to run prior to commercial sale, the commercial value of the product may be limited. In addition, patents may not provide adequate protection in certain countries in Africa and Asia, including China.

      Our competitors may file patent applications covering our technology. If so, we may have to participate in interference proceedings or litigation to determine the right to a patent. Litigation and interference proceedings are expensive even if we are ultimately successful.

      Our success depends in large part on our ability to operate without infringing upon the patents or other proprietary rights of third parties. If we infringe the patents of others, we may be prevented from commercializing products or may be required to obtain licenses from these third parties. We cannot be certain that we wouldmay not be able to obtain alternative technologies or any required license. Even if we were to obtain such technologieslicense on reasonable terms or licenses, we cannot be certain that the terms would be reasonable.at all. If we fail to obtain such licenses or alternative technologies, we may be unable to develop or commercialize some or all of our products.

      In addition, we use significant proprietary technology and rely on unpatented trade secrets and proprietary know-how to protect certain aspects of our production and other technologies. Our trade secrets may become known or independently discovered by our competitors.

      In some countries, weWe may be required to grant compulsory licenses forface significant liability resulting from our HIV products or face generic competition for our HIV products.

              In a number of developing countries, government officials and other groups have suggested that pharmaceutical companies should make drugs for HIV infection available at a low cost. In some cases, governmental authorities have indicated that where pharmaceutical companies do not do so, their patents might not be enforceable to prevent generic competition. Some major pharmaceutical companies have greatly reduced prices for HIV drugs in certain developing countries. If certain countries do not permit enforcement of our patents, sales of Viread in those countries could be reduced by generic competition. Alternatively, governments in those countries could require that we grant compulsory licenses to allow competitors to manufacture and sell their own versions of Viread in those countries, thereby reducing our Viread sales, or we could respond to governmental concerns by reducing prices for Viread. In all of these situations, our results of operations could be adversely affected.

      Manufacturing problems could delay product shipments and regulatory approvals.

              We depend on these third parties to perform manufacturing obligations effectively and on a timely basis. If these third parties fail to perform as required, this could impair our ability to deliver our

      31



      products on a timely basis or cause delays in our clinical trials and applications for regulatory approval, and these events could harm our competitive position. For Viread, Hepsera and Vistide, we rely on third parties for the manufacture of bulk drug substance and final drug product for clinical and commercial purposes. For example, Roche is responsible for manufacturing Tamiflu. In January 2002, Roche announced that due to production problems the liquid suspension form of Tamiflu approved for treatment of children as young as one year old was not available; however, the liquid suspension form of Tamiflu was returned to market in time for the 2002-2003 flu season. These production issues did not affect availability of the tablet form of Tamiflu for adults and adolescents 13 years and older. In Japan, where the 2002-2003 flu season has been particularly severe, Roche's sublicensee, Chugai Corporation, has been unable to meet heightened demand satisfactorily. In January 2003, Chugai issued a press release attributing this failure, in part, to manufacturing problems. These problems in Japan have reduced the net sales on which our royalty with Roche is based. Additionally, for emtricitabine, we are seeking qualification of Abbott in the U.S. and the European Union as a contract manufacturer for bulk drug substance and the final drug product. We are also seeking qualification in the European Union for a second contract manufacturer for emtricitabine bulk drug substance. Abbott has a recent history of violations of current Good Manufacturing Practice regulations cited by the FDA and has been working towards corrections under an FDA consent decree. The FDA conducted a pre-approval inspection at Abbott for the new drug application of emtricitabine and issued a Form 483 observation to Abbott in December 2002. In January 2003, Abbott submitted a response to the Form 483 observation. If the FDA deems Abbott's response to the Form 483 observation to be inadequate, or if Abbott is unable to supply the initial launch quantities of emtricitabine in a timely manner, the emtricitabine launch could be delayed.

              We manufacture AmBisome and DaunoXome at our facilities in San Dimas, California. Our only formulation and manufacturing facilities are in San Dimas, California, although we own a manufacturing facility in Ireland that performs certain quality control testing, labeling and packaging, and we use third parties as alternate contract suppliers to fill and freeze dry certain batches of product. In the event of a natural disaster, including an earthquake, equipment failure, strike or other difficulty, we may be unable to replace this manufacturing capacity in a timely manner and would be unable to manufacture AmBisome and DaunoXome to meet market needs.

      We may not be able to obtain materials necessary to manufacture our products.

              Many of the materials that we utilize in our operations are made at only one facility. For example, we depend on single suppliers for high quality amphotericin B, daunorubicin HCl, distearoylphosphatidylcholine and high quality cholesterol, each of which is used in the manufacture of one or more of our liposomal products. Because the suppliers of key components and materials must be named in the new drug application filed with the FDA for a product, significant delays can occur if the qualification of a new supplier is required. If supplies from our suppliers were interrupted for any reason, we may be unable to ship Viread, AmBisome, Hepsera, Vistide or DaunoXome, or to supply any of our products in development for clinical trials.

      We have limited experience in manufacturing our existing products and may need to develop additional manufacturing capacity for these products and our potential future products.

              For some of our potential products under development, we will need to develop further our production technologies for use on a larger scale in order to conduct clinical trials and produce such products for commercial sale at an acceptable cost. We cannot be certain that we will be able to implement any of these developments successfully.

              The manufacturing process for pharmaceutical products is highly regulated, and regulators may shut down manufacturing facilities that they believe do not comply with regulations. The FDA's current Good Manufacturing Practices are extensive regulations governing manufacturing processes, stability

      32



      testing, record-keeping and quality standards. In addition, our manufacturing operations are subject to routine inspections by regulatory agencies and similar regulations are in effect in other countries.

      Our business may give rise to product liability claims not covered by insurance or indemnity agreements.and successful claims could materially reduce our earnings.

      The testing, manufacturing, marketing and use of Viread, AmBisome, Hepsera, Emtriva, Tamiflu, Vistide and DaunoXome,Vistide as well as products in development, involve substantial risk of product liability claims. These claims may be made directly by consumers, healthcare providers, pharmaceutical companies or others. AAlthough we maintain product liability insurance, a successful product liability claim against us may not be covered by our insurance or could require us to pay substantial amounts beyond that provided by our insurance, either of which could impair our financial condition and our ability to clinically test and to market our products.

              Additionally, we are required by governmental regulations to test our products even after they have been sold and used by patients. As a result of such tests, we may be required to, or may determine that, we should recall products already in the market. Subsequent testing and product recalls may increase our potential exposure to product liability claims.

      Our internal research programs and our efforts to obtain rights to new products from third parties may not yield potential products for clinical development.

              Our long term success depends on our ability either to identify, through internal research programs, potential product candidates that may be developed into new pharmaceutical products or to obtain new products or product candidates through licenses from third parties.

              A significant portion of the research that we will conduct will involve new and unproven technologies. Research programs to identify product candidates require substantial technical, financial and human resources whether or not such candidates are identified. Our research programs may appear to be a promising route to identifying potential product candidates yet fail to yield product candidates for clinical development for a number of reasons, including:

        the research methodology used may not be successful in identifying potential product candidates;

        potential product candidates may on further study be shown to have unduly harmful side effects or characteristics that indicate they are unlikely to be effective drugs;

        we may be unable to develop larger scale manufacturing methods that are efficient, cost-effective and capable of meeting stringent regulatory standards; or

        others may hold intellectual property rights that prevent us from developing, making or selling certain products.

              We may be unable to obtain suitable product candidates or products from third parties for a number of reasons, including:

        we may be unable to purchase or license such compounds on terms that would allow us to make an appropriate return from the product;

        competitors may be unwilling to assign or license product rights to us;

        we may be unable to identify suitable products or product candidates within our areas of expertise; or

        product candidates that we acquire may not be approved by regulatory authorities due to problems with their safety or effectiveness.

              If we are unable to develop suitable potential product candidates through internal research programs or obtain rights to new products from third parties, our future revenue growth will suffer.

      33



      Our use of hazardous materials, chemicals, viruses and radioactive compounds exposes us to potential liabilities.

              Our research and development involves the controlled use of hazardous materials, chemicals, viruses and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, we cannot completely eliminate the risk of accidental contamination or injury from these materials. In the event of such an accident, we could be held liable for significant damages or fines.


      Risks Related to Triangle Acquisition in January 2003

      Emtricitabine may not receive marketing approval as a single agent, which could prevent or delay the commercial sale of a co-formulation of Viread with emtricitabine.

              We have submitted applications for marketing approval of emtricitabine for the treatment of HIV infection in the U.S. and in the European Union. Our ability to obtain marketing approval for a co-formulation of Viread with emtricitabine will depend on emtricitabine receiving marketing approval as a single agent for treatment of HIV infection. Regulatory authorities in the U.S., European Union and other countries may not grant marketing approval for emtricitabine if they conclude it is not safe or efficacious for its intended use. In addition, because regulatory authorities in the European Union require that new products have sufficient efficacy or safety advantages over currently marketed products and have extensive pre-clinical toxicity data, these authorities may conclude that emtricitabine is not approvable as a single agent. Emtricitabine is similar at a chemical level to Epivir, GSK's lamivudine product that is already marketed for treatment of HIV infection, and available data indicates that the products have comparable safety and efficacy profiles. If emtricitabine does not receive marketing approval as a single agent, we may be unable to obtain marketing approval for a co-formulation of Viread with emtricitabine or may have to conduct lengthy and expensive clinical trials of the co-formulation in order to obtain such approvals.

      The proposed co-formulation of Viread and emtricitabine may not be technically possible, may not be effective or safe, or may not be approved by regulatory authorities.

              We intend to develop and commercialize a co-formulation of Viread with emtricitabine. Achieving anticipated synergies and the potential benefits of a co-formulation, which were the significant motivations behind our merger with Triangle, will depend on successfully creating and obtaining marketing approval for a co-formulation of Viread with emtricitabine. We expect that if emtricitabine receives marketing approval, the only major requirement for obtaining marketing approval for the co-formulation of Viread with emtricitabine would be a clinical study showing that the co-formulation of emtricitabine and Viread is biologically equivalent to emtricitabine and Viread administered together as separate formulations. We will need a chemistry, manufacturing and bioequivalence package that shows the co-formulated tablet gives the same exposure to Viread and emtricitabine as the two drugs given individually. It is uncertain whether it will be possible to bring such a co-formulation to market. Emtricitabine has not been approved for marketing by regulatory authorities and may not be approved or might require additional clinical trials in order to obtain regulatory approval. In addition, a physical combination of emtricitabine with Viread may not be technically feasible or cost-effective. Even if the two drugs can be co-formulated, regulatory authorities may not approve the co-formulation or may require additional clinical trials before granting marketing approval. Any requirement for clinical trials, or any delay or failure in developing and commercializing a co-formulation of emtricitabine and Viread, would have a material adverse effect on our business, financial condition and results of operations.

      34



      If we do not successfully integrate Triangle into our operations, our business will be adversely affected.

              Integrating Gilead and Triangle will be a complex and time-consuming process. Prior to the merger, Gilead and Triangle operated independently, each with its own business, corporate culture, locations, employees and systems. Gilead and Triangle now have to operate as a combined organization and begin utilizing common information and communication systems; operating procedures; financial controls; and human resource practices, including benefits, training and professional development programs. There may be substantial difficulties, costs and delays involved in any integration of Gilead and Triangle. These may include:

        distracting management from the business of the combined company;

        potential incompatibility of corporate cultures;

        potential inability to coordinate research and development efforts successfully;

        costs and delays in implementing common systems and procedures; and

        operating the combined company at three sites in the U.S. and at nine international sites.

              Any one or all of these factors may increase operating costs or lower anticipated financial performance. In addition, the combined company may lose corporate partners, distributors, suppliers, manufacturers and employees. Many of these factors are also outside the control of the company. Achieving anticipated synergies and the potential benefits underlying the two companies' reasons for the merger will depend on successful integration of the two companies. The failure to integrate Gilead and Triangle successfully would have a material adverse effect on our business, financial condition and results of operations.

      If we are unable to manufacture emtricitabine successfully or at a reasonable cost, our potential future results could suffer.

              We have not manufactured emtricitabine and are not familiar with the manufacturing process for emtricitabine. Until completion of the merger, Triangle was responsible for making arrangements to obtain supplies of emtricitabine from a third party for an anticipated commercial launch following receipt of marketing approvals in the U.S. and the European Union. If Triangle has not made adequate arrangements for supplies, or if there are supply problems with the third party manufacturers for emtricitabine, there may not be sufficient supplies of emtricitabine to meet commercial demand, in which case our future results could suffer.

              Triangle entered into an agreement with Abbott, under which Abbott has agreed to manufacture emtricitabine bulk drug substance and final drug product for us and to transfer the manufacturing technology for emtricitabine to third party manufacturers. We will rely on Abbott or on such third parties for manufacture of emtricitabine for some period of time. We are seeking qualification of Abbott in the U.S. and the European Union as a contract manufacturer. Abbott has a recent history of violations of current Good Manufacturing Practice regulations cited by the FDA and has been working towards corrections under an FDA consent decree. The FDA conducted a pre-approval inspection at Abbott for the new drug application of emtricitabine and issued a Form 483 observation to Abbott in December 2002. In January 2003, Abbott submitted a response to the Form 483 observation. We depend on Abbott to perform its obligations effectively and on a timely basis. If the FDA deems Abbott's response to the Form 483 observation to be inadequate, or if Abbott is unable to supply the initial launch quantities of emtricitabine in a timely manner, the timing of the emtricitabine launch could be impacted and this event could harm our competitive position. Any new manufacturers for emtricitabine would also have to be approved by regulatory authorities, and if there are delays in such approval, we may have to rely on Abbott for emtricitabine supplies for a longer period than currently anticipated. If costs for supplies of emtricitabine from these third party manufacturers are unacceptably

      35



      high, our results of operations would suffer until we are able to arrange for manufacture of emtricitabine at lower cost. Because we have not manufactured emtricitabine before, we cannot be sure that the emtricitabine manufacturing costs can be reduced to an acceptable level.

      Our profitability will depend in part upon Triangle's operations, which have incurred losses since Triangle's inception.

              Triangle has incurred losses since its inception and as of December 31, 2002, its accumulated deficit was approximately $441.6 million. Triangle's losses have resulted primarily from expenses associated with the acquisition and development of its drug candidates and general and administrative costs. Triangle has not generated any revenue from the sale of its product candidates to date and was not expecting to do so before 2003. Triangle's operations may never generate significant revenue or achieve profitability.

      The trading price of our securities could be subject to significant fluctuations.

              The trading price of our common stock has been volatile, and may be volatile in the future. Factors such as announcements of fluctuations in our or our competitors' operating results, changes in our prospects and market conditions for biotechnology stocks in general could have a significant impact on the future trading prices of our common stock. In particular, the trading price of the common stock of many biotechnology companies, including us, has experienced extreme price and volume fluctuations, which have at times been unrelated to the operating performance of such companies whose stocks were affected. Some of the factors that may cause volatility in the price of our securities include:

        clinical trial results and regulatory developments;

        quarterly variations in results;

        business and product market cycles;

        fluctuations in customer requirements;

        the availability and utilization of manufacturing capacity;

        the timing of new product introductions; and

        the ability to develop and implement new technologies.

              The price of our securities may also be affected by the estimates and projections of the investment community, general economic and market conditions, and the cost of operations in our product markets. While we cannot predict the individual effect that these factors may have on the price of our securities, these factors, either individually or in the aggregate, could result in significant variations in price during any given period of time. There can be no assurance that these factors will not have an adverse effect on the trading prices of our common stock.


      ITEM 2. PROPERTIES

      Our corporate headquarters, including our principal executive offices and some of our research facilities, are located in Foster City, California. At this location, we leaseown approximately 260,000496,000 square feet of space in eight16 proximately located buildings. OneWe currently occupy 10 of the leases covering approximately 59,000 square feet16 buildings and also have a tenant occupying some of space in this group of buildings expires in December 2003 and there are no renewal options.

      We also occupy facilities in San Dimas, California. At this location, we lease approximately 102,500 square feet of space, which houses research and development activities, manufacturing and certain administrative functions. These leases expire in May 2008 and November 2003,2013, with two five-yearno renewal

      In Durham, North Carolina, we lease approximately 101,000 square feet of administrative office and laboratory space, of which we sublease approximately 21,000 square feet to third parties. This lease expires in September 2003. We are currently in negotiations withOctober 2009, after which Gilead has the lessoroption to renew for another lease term.two seven-year terms.

      In addition, we lease approximately 85,000141,000 square feet of space for our sales and marketing, regulatory, finance, information technology and human resource operations in Europe and Australia, including a prepaid, 999-year lease for our 13,000 square foot manufacturing and distribution facility in Ireland. The other leases have various expiration dates.

      We believe that our facilities are adequate and suitable for at least our current and near-term future needs.


      ITEM 3. LEGAL PROCEEDINGS

              In 1997, we reached a settlement with Elan Corporation, plc (the successor company to The Liposome Company) in which both companies agreed to dismiss all legal proceedings involving AmBisome. Under the terms of the initial settlement agreement in 1997, we made an initial payment to Elan of $1.8 million and agreed to make additional royalty payments through 2006, based on AmBisome sales. In 1997, we recorded a $10.0 million accounting charge for the accrued litigation settlement expenses, representing the net present value of all future minimum payments we were required to make. In June 2002, weOn September 4, 2003, Gilead entered into an agreementa Settlement Agreement and Release with Elan terminating our remaining AmBisome payment obligations under the initial settlement agreement in exchange for a paymentUniversity License Equity Holdings, Inc. (ULEHI) and Archemix Corporation concerning rights to Elan of $7.3 million.

              In November 2002, ULEHI notified us that ULEHI believes Gilead has materially breached its licensing agreement with ULEHI concerningidentify aptamers using the SELEX technology licensed by ULEHI to Gilead. The Settlement Agreement and Release resolves disputes among the parties arising out of Gilead’s assignment of rights to identify certain aptamers to Archemix.

      On September 2, 2003, the County of Westchester, New York (“Westchester”) served Gilead with a complaint filed in the United States District Court for the Southern District of New York which alleges that Gilead and a large number of other pharmaceutical manufacturer defendants report prices for products that overstate the Average Wholesale Price (“AWP”), allegedly inflating reimbursement rates under the Medicaid Program and causing Westchester to pay artificially inflated prices for covered drugs including, in the case of Gilead, Viread. In addition, Westchester argues that the defendants, including Gilead, did not accurately report the “best price” under the Medicaid Program. The complaint asserts varying claims under the federal RICO statutes, their state law corollaries, as well as state law claims for deceptive trade practices and common law fraud. Gilead intends to vigorously defend itself against the allegations. The complaint seeks an undetermined amount of damages, as well as other relief, including declaratory and injunctive relief. Other defendants in this lawsuit have been named in numerous other lawsuits with comparable AWP allegations. To our knowledge, Gilead has not been named in these other lawsuits. Were Gilead to be named and served in other lawsuits with comparable AWP allegations, adverse results could result in material damages.

      A purported class action complaint was filed on November 10, 2003 in the United States District Court for the Northern District of California against Gilead and our Company’s Chief Executive Officer, Chief Financial Officer, Executive Vice Presidents of Operations and Research and Development, and Senior Vice Presidents of Manufacturing and Research. The complaint alleges that the defendants violated the federal securities laws, specifically Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 of the Securities and Exchange Commission, by amongstmaking certain alleged false and misleading statements. The plaintiff seeks unspecified damages on behalf of a purported class of purchasers of the Gilead’s securities during the period from July 14, 2003 through October 28, 2003. Other similar actions were subsequently filed and the court issued an order consolidating the lawsuits into a single action on December 22, 2003. We believe that we have meritorious defenses to the allegations contained in the complaint and intend to defend the case vigorously. No trial date has been scheduled. On February 9, 2004, the court issued an order appointing lead plaintiffs in the action, and these lead plaintiffs have until March 25, 2004 to file a consolidated complaint.

      In December 2003, two purported shareholder derivative lawsuits were filed by individual shareholders on behalf of Gilead against its directors and certain executive officers in the Superior Court of the State of California, County of San Mateo alleging, among other things, assigning rights underthat defendants violated the agreement without ULEHI's consent.California Corporations Code and breached fiduciary duties owing to Gilead. Gilead is named as a


      nominal defendant. The plaintiffs seek unspecified damages on behalf of Gilead in connection with alleged insider trading during the period between July 14, 2003 and October 28, 2003 and defendants’ alleged breach of their fiduciary duties, abuse of control, waste and mismanagement. The two cases were consolidated into a single action on January 15, 2004 and plaintiffs filed a consolidated complaint on February 12, 2004. No trial date has been scheduled. We contest ULEHI's allegations. We have metintend to take all appropriate action to defend our interests in connection with ULEHI regarding these allegations and are actively engaged in negotiations to settle this disagreement. If these negotiations prove unsuccessful and ULEHI chooses to terminate the ULEHI-Gilead agreement, an arbitration concerning this termination would likely result. An unfavorable outcome in such an arbitration could give rise to an award against us of monetary damages or other adverse remedies, possibly including conveyance to ULEHI of Gilead's rights and obligations under the ULEHI licensing agreement and our sublicenses.litigation.

      We are also a party to various other legal actions that arose in the ordinary course of our business. We do not believe that any of these other legal actions will have any significanta material adverse impact on our business.business, results of operations or financial position.

                During 2003, Gilead completed the acquisition of all of the net assets of Triangle for an aggregate purchase price of $525.2 million. Approximately $488.6 million of the purchase price was allocated to in-process research and development. Also during 2003, we recorded an income tax benefit of $111.6 million related to the reduction of the valuation allowance on certain of our net deferred tax assets.

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

      OverviewExecutive Summary

              Gilead was incorporated in Delaware on June 22, 1987. We are a biopharmaceutical company focused onthat discovers, develops and commercializes therapeutics to advance the discovery, development and commercializationcare of antivirals, antibacterials and antifungals to treatpatients suffering from life-threatening infectious diseases. We are a multinational company, with revenues from six approved products and marketing operations in ten countries. We focus our research and clinical programs on anti-infectives. Currently, we market Viread (tenofovir disoproxil fumarate) and Emtriva (emtricitabine) for the treatment of HIV infection; Hepsera (adefovir dipivoxil) for the treatment of chronic hepatitis B infection; AmBisome ((amphotericin B)(amphotericin B liposome for injection), an antifungal agent; DaunoXome (daunorubicin citrate liposome injection), a drug approved for the treatment of Kaposi's Sarcoma; and Vistide (cidofovir injection) for the treatment of CMV retinitis. Roche markets Tamiflu (oseltamivir phosphate) for the treatment of influenza, under a royalty paying collaborative agreement with us. In December 2003, we made the decision to discontinue selling DaunoXome (daunorubicin citrate liposome injection), a drug approved for the treatment of Kaposi’s Sarcoma. We are seeking to add to our existing portfolio of products through our internal discovery and clinical development programs internal discovery programs and through an


      active product acquisition and in-licensing strategy, such as our acquisition of the assets of Triangle Pharmaceuticals, Inc. completed in January 2003. Our internal discovery activities include identification of new molecular targets, target screening and medicinal chemistry. In addition, we are currently developing clinical stage products to treat HIV infection and HBV infections.chronic hepatitis B.

      Our operating results for 2003 in comparison to 2002 were characterized by solid growth in our key HIV drug, Viread and represent our second consecutive year of significant increases in total product revenues. Based on independent third party data, Viread has become one of the most widely prescribed antiretrovirals in its class of drugs, achieving more new and total prescriptions than competing drugs in the nucleotide/nucleoside reverse transcriptase inhibitor (NRTI) market. As a result of the growth of Viread sales, higher than expected AmBisome sales and controlled spending, we have generated positive cash flow from operations for each of the last two years, with an increase to $234.6 million in 2003 from $74.4 million in 2002, or 215% year over year growth. We expect our HIV drug sales to grow in the near term, although we expect it to be at a slower rate than we have experienced in the past two years. Enabling this growth is the increasing importance of once-daily regimens in prescribing HIV medications. The availability of both Viread and Emtriva (acquired from Triangle) now provide physicians the ability to construct once-daily regimens.

      Operating results for 2003 were impacted by the acquisition of all of the assets of Triangle in January 2003. We completed this acquisition to expand our antiviral pipeline. Triangle was a development stage company with a particular focus on potential therapies for HIV, including AIDS, and the hepatitis B virus (HBV). The aggregate purchase price was $525.2 million, including cash paid of $463.1 million for the outstanding stock, the fair value of stock options assumed of $41.3 million, estimated direct transaction costs of $14.2 million and employee related costs of $6.6 million. Approximately $488.6 million of the purchase price was allocated to in-process research and development and represented the fair value of Triangle’s incomplete research and development programs that had not yet reached technological feasibility and had no alternative future use as of the acquisition date. As a result of this transaction and the related in-process research and development charge, our operating loss for 2003 was $158.7 million versus operating income of $81.0 million in 2002. This acquisition was important to us not only for the compounds we acquired, but also have expertise in liposomal drug delivery technologyfor the opportunity it provided us to create a co-formulation of Viread and Emtriva into a single pill that can be dosed once a day. If successful, we useexpect this co-formulated product to develop drugs that are safer, easierfurther grow our HIV franchise. See Note 3 to the consolidated financial statements for patients to tolerate and more effective.further information on the Triangle acquisition.

      In December 2001, we completed the sale of our oncology assets to OSI Pharmaceuticals, Inc. in a transaction valued at up to $200.0 million in cash and OSI stock. This transaction will allowhas allowed us to focus on and continue to strengthen our core expertise in infectious diseases. See Note 46 to the consolidated financial statements for further information.

              In the year ended December 31, 2001, Gilead adopted Statement of Financial Accounting Standards Nos. 133 and 138, collectively referred to as SFAS 133,Accounting for Derivative Instruments and Hedging Activities, which resulted in a cumulative effect of change in accounting principle. In the year ended December 31, 2000, Gilead adopted the Securities and Exchange Commission's Staff Accounting Bulletin No. 101,Revenue Recognition in Financial Statements, also resulting in a cumulative effect of change in accounting principle.

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

      Forward-Looking Statements and Risk Factors

      The following discussion contains forward-looking statements that involve risks and uncertainties. Gilead's actual results could differ materially from those discussedPlease read “Risk Factors that Affect Gilead” in any forward-looking statements. FactorsPart I for factors that could cause or contribute to suchmaterial differences include, but are not limited to, those discussed in this section, as well as under the caption "Business", including "Risk Factors That Affect Gilead" in Part I. Allbetween these forward-looking statements included in this document are based on information currently available to Gilead, do not include the effect of the acquisition of Triangle in our 2003 guidance, unless specifically noted, since we are still evaluating the detailed financial impact of Triangle's operations on our consolidated financial statements, and we assume no obligation to update any such forward-looking statements.actual results. The following“Risk Factors” discussion should be read in conjunction with the consolidated financial statements and notes included elsewhere in this report.

              Viread Sales.    We rely on sales of Viread for a significant portion of our operating income. A number of drugs to treat HIV infection and AIDS are currently sold or are in advanced stages of clinical development, including 20 products currently sold in the U.S. Among the companies that are significant competitors in the HIV/AIDS market are GSK, BMS, Roche, Pfizer, Merck, Boehringer-Ingelheim and Abbott Laboratories. Given the broad range of competitors and depth of their36



      41



      resources, Viread's market penetration may be limited, particularly for use in treatment-naïve patients, given that the data supporting Viread's U.S. approval is in a treatment-experienced patient population.

              AmBisome Sales.    We also rely on sales of AmBisome for a significant portion of our operating income. There are lower priced products that compete with AmBisome; two products that compete with AmBisome that were recently approved in the U.S. and European Union; and products being developed that could compete with AmBisome in the future. If any of these antifungal products achieve further market acceptance, or if the antifungal products in development become commercially available, revenues from sales of AmBisome would likely decrease, resulting in a reduction of operating income.

              Acquisition Integration.    In January 2003, we completed the acquisition of Triangle. Any acquisition carries inherent risks. We may not be able to successfully integrate Triangle into our operations and obtain any anticipated synergies or cost savings. We may also be unsuccessful in obtaining marketing approval for emtricitabine or in developing a co-formulated product. Failure to successfully integrate the Triangle operations into our business or obtain marketing approval of emtricitabine could adversely affect our financial position and results of operations.

              Market Acceptance of Products.    The ability of our products to achieve and sustain market acceptance will depend on a number of factors, including the receipt and scope of regulatory approvals; the availability of public and private insurance and reimbursement for our products; the safety, efficacy, tolerability and cost of our products; ease of administration and dosing, and how our products compare to competitive products. If our products do not achieve and sustain market acceptance, our results of operations will suffer.

              Regulatory Process.    The U.S. Food and Drug Administration and foreign agencies could reject or limit the commercialization of our products for a number of reasons including: if they disagree with the results or designs of our clinical trials; if they believe our products have unacceptable efficacy, toxicity or tolerability; or if they believe our products cannot be manufactured on a commercial basis in compliance with the applicable safety and quality standards. If these agencies reject or limit the commercialization of our products, our financial results would be adversely affected. The clinical trials required for regulatory approval of our products are extremely expensive, and it is difficult for us to accurately predict or control the amount or timing of these expenses from quarter to quarter. In addition, regulatory agencies could require us to conduct additional unanticipated clinical trials on our products, the cost of which could be substantial.

              Governmental Legislation and Reimbursement Programs.    Regulatory, legal and legislative issues may adversely affect pricing and sales of our products. In the U.S., there is federal legislation that lowers the price for our products that are purchased or reimbursed by federal agencies, and some states have enacted legislation that can lower the prices for our products. In addition, there are a growing number of U.S. federal and state legislative proposals that if enacted would lower the price for our products. Many countries outside the U.S. have government sponsored health care programs that set lower drug prices and patient reimbursement levels. Our sales in countries with relatively higher prices may be reduced if products can be imported into those countries from lower price markets. This is of particular concern in the European Union where we are required to permit cross border sales and could be a concern in the U.S. if legislation easing import restrictions is enacted and applied.

              International Credit Risk.    We are subject to credit risk from our accounts receivable related to European product sales. Our European product sales to government owned or supported customers in Greece, Spain, Portugal and Italy are subject to significant payment delays due to government funding and reimbursement practices. If significant changes were to occur in the reimbursement practices of European governments or if government funding becomes unavailable, our financial position and results of operations would be adversely affected.

      42



              Compulsory Licensing and Generic Competition.    In a number of developing countries, government officials and other groups have suggested that pharmaceutical companies should make drugs for HIV infection available at a low cost. In some cases, governmental authorities have indicated that where pharmaceutical companies do not do so, their patents might not be enforceable to prevent generic competition. Some major pharmaceutical companies have greatly reduced prices for HIV drugs in certain developing countries. If certain countries do not permit enforcement of our patents, sales of Viread in those countries could be reduced by generic competition. Alternatively, governments in those countries could require that we grant compulsory licenses to allow competitors to manufacture and sell their own versions of Viread in those countries, thereby reducing our Viread sales, or we could respond to governmental concerns by reducing prices for Viread. In all of these situations, our results of operations could be adversely affected.

              Collaborations.    We depend on collaborations for the development and commercialization of certain products and for revenue, including the collaboration with Fujisawa for sales of AmBisome in the U.S. and Canada, the collaboration with GSK for clinical and regulatory development and commercialization of Hepsera in Asia, Latin America and certain other territories, and the collaboration with Roche for sales of Tamiflu worldwide. We may also seek additional collaborations. These collaborations could fail for a number of reasons, including if our partners do not devote sufficient resources to the development, commercialization or marketing of our products, or if disputes arise with our partners. If these existing collaborations fail, our financial results would be adversely affected.

              Foreign Currency Fluctuations.    A significant percentage of our product sales are denominated in foreign currencies. Increases in the value of the U.S. dollar against these foreign currencies in the past have reduced, and in the future may reduce, our U.S. dollar return on these sales and negatively impact our financial condition. Prior to January 2002, we did not hedge our exposure to the impact of fluctuating foreign exchange rates on forecasted sales. Effective January 2002, we have begun to use forward contracts to hedge a percentage of our forecasted international sales, primarily those denominated in the Euro currency. We do hedge a portion of our accounts receivable balances denominated in foreign currencies, which minimizes but does not eliminate our exposure to currency fluctuations between the date a sale is recorded and the date that cash is collected. Additionally, to mitigate the impact of currency rate fluctuations on our cash outflows for certain foreign currency-denominated raw materials purchases, we enter into foreign exchange forward contracts to hedge our foreign currency-denominated accounts payable.

              Uncertain Financial Results.    We expect that our financial results will continue to fluctuate from quarter to quarter and that such fluctuations may be substantial. The fluctuations can be caused by many factors that are beyond our control, including the risk factors listed above. As of December 31, 2002, our accumulated deficit was $381.6 million.

      Critical Accounting Policies, Estimates and EstimatesJudgments

              Gilead'sThis discussion and analysis of its financial condition and results of operations areis based upon itsour consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of assets and liabilities.disclosures. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, bad debts, inventories, accrued clinical and preclinical expenses, income taxes and contingencies. We base our estimates on historical experience and on various other market specificmarket-specific assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of

      43



      assets and liabilities that are not readily apparent from other sources. Actual results, however, may differ significantly from these estimates.

              Gilead believesWe believe the following critical accounting policies reflect itsthe more significant judgments and estimates used in the preparation of itsour consolidated financial statements:

        ·We record estimated reductions to revenue for expected returns of expired products, government rebate programs, such as Medicaid reimbursements, and customer incentives, such as cash discounts for prompt payment. Estimates for Medicaid reimbursementsgovernment rebate programs and cash discounts are based on contractual terms, historical utilization rates and expectations regarding thefuture utilization rates for these programs. Estimates for product returns, including new products, are based on an on-going analysis of industry and historical return patterns. This includes monitoring the feedback that we receive from our sales force regarding customer use and satisfaction, the purchase of third-party data to assist us in monitoring channel inventory levels and subsequent prescriptions as well as, for new products, a review of our other long shelf life products we have sold through the same or similar channels. Further, we monitor the activities and clinical trials of our key competitors and assess the potential impact on our future sales and return expectations where necessary. Expected returns for our marketed drugs are generally low because the shelf life for these products ranges from 24 months for Viread up to 36 months for AmBisome in the U.S. If conditions become more competitive for any of the markets served by our drugs or if other circumstances change, we may take actions to increase our product return estimates or we may offer additional customer incentives. This would result in an incremental reduction of future revenue at the time the return estimate is changed or incentives are offered.

        For example, between 2002 and 2003, we increased our reserve for government discounts on Viread sales by more than 3% as a result of our review of historical utilization rates and the impact of a 2003 mid-year price increase for Viread. We could see similar increases in the future based on our continued reviews of utilization rates and any potential U.S. price increases for Viread.

        ·We also maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. This allowance is based on our analysis of several factors including, but not limited to, historical payment patterns of our customers and individual customer circumstances, an analysis of days sales outstanding by customer and geographic region, and a review of the local economic environment and its potential impact on the government funding and reimbursement practices. If the financial condition of our customers or the economic environment in which they operate were to deteriorate, resulting in an inability to make payments, additional allowances may be required. Our allowance for doubtful accounts balance as a percentage of total accounts receivable did not materially change from December 31, 2002 to December 31, 2003. We believe that the allowance for doubtful accounts is adequate to cover anticipated losses under current conditions; however, significant deterioration in any of the above factors, especially with respect to the government funding and reimbursement practices in the European market, could materially change these expectations and result in an increase to our allowance for doubtful accounts.



      ·We write down our inventory based on historical review of the quantity of raw material bad batches experienced in a given year and expectations of production and inventory levels. We also perform quality control reviews of our individual raw material batches. We generally do not maintain inventory reserves based on estimated obsolescence or risk of competition primarily because the shelf life of the products is long. However, if our current assumptions about future production or inventory levels, demand and competition were to change and if actual market conditions are less favorable than those projected by management, additional inventory reserves may be required.

      required which could negatively impact our product gross margins.

      ·We record accruals for estimated clinical and preclinical study costs. Most of our clinical and preclinical studies are performed by third party contract research organizations (CROs). These costs are a significant component of research and development expenses. Management accruesDuring 2003, 2002, and 2001, we incurred $15.0 million, $23.9 million and $33.6 million, respectively, of CRO costs. We accrue costs for clinical studies performed by contract research organizations based on estimates that, generally, 25% to 30% of the work is for up-front costs with the remaining activity occurringCROs on a straight-line basis over the lifeterm of the individualservice period and adjust our estimates, if required, based upon our on-going review of the level of effort actually incurred by the CRO. Initially we estimate that the work performed under the contracts occurs ratably over the periods to the expected milestone, event or total contract or study. This estimatecompletion date. The expected completion dates are estimated based upon the terms of the contracts and past experience with similar contracts. These estimates may or may not match the actual services performed by the organizations as determined by patient enrollment levels and related activities. We monitorother measures of activities specified in the contract. As a result, we validate our accruals quarterly through written vendor confirmations and detailed reviews of the activities performed under each contract. Based upon the results of these validation processes, we assess the appropriateness of our accruals and make any adjustments we deem necessary so that our expenses reflect the actual effort incurred by the CROs. Generally, a significant portion of the total costs are associated with start up activities for the trial and patient enrollment levelsenrollment. Gilead extensively outsources its clinical trial activities and usually performs only a small portion of the start-up activities in-house. As a result, CROs typically perform most of the total start-up activities for our trials, including document preparation, site identification, screening and preparation, pre-study visits, training, and program management. On a budgeted basis, these costs are typically 25% to 30% of the total contract value. On an actual basis, this percentage range is significantly wider as many of our contracts are either expanded or contracted in scope compared to the original budget while the start-up costs for the particular trial do not change significantly. Start-up costs usually occur within a few months after the contract has been established and are milestone or event driven in nature. The remaining activities and related costs, such as patient monitoring and administration, generally occur ratably throughout the life of the individual contract or study. Most contracts are negotiated as fixed price and can vary in length between six months for a single dose Phase 1 study and up to two years or more for a more complex Phase 3 study. The average length of contract for 2002 and 2003 has been at the upper end of this range in order to provide long term safety and efficacy data to support the commercial launches of Viread, Hepsera and Emtriva. Through December 31, 2003, we have not understated or overstated activity tolevels for any particular study such that a material adjustment was required. All of our material CRO contracts are terminable by us upon written notice and Gilead is generally only liable for actual effort expended by the extent possible, however,CRO at any point in time during the contract, regardless of payment status. Amounts paid in advance of services being performed will be refunded if a contract is terminated. However, if management does not receive complete and accurate information from our vendors or has underestimated activity levels associated with various studiesa study at a given point in time, we would have to record additional and potentially significant research and development expenses in future periodsperiods.

      ·       We develop our income tax provision including deferred tax assets and liabilities based on significant management judgment. We record a valuation allowance to reduce our deferred tax


      assets to the amount that couldis likely to be significant.

      realized. We consider future taxable income, ongoing tax planning strategies and our historical financial performance in assessing the need for a valuation allowance. If it were determined that we would be able to realize certain deferred tax assets related to the valuation allowance, an adjustment to the deferred tax asset would increase income in the period in which such determination was made. Such an adjustment was made in the fourth quarter of 2003 when we determined that it was more likely than not that certain of our deferred tax assets will be realized and therefore released the related valuation allowance. This resulted in an income tax benefit of approximately $111.6 milion. Likewise, if we determine that we would not be able to realize all or part of our deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period in which such determination was made. We evaluate the realizibility of our deferred tax assets on a quarterly basis. Our future effective tax rate may be affected by such factors as changes in tax laws or rates, changes in interpretation to these laws and overall changes in future levels of earnings and research and development and capital spending.

      Management has discussed the development and selection of these critical accounting policies with the Audit Committee of Gilead’s Board of Directors and the Audit Committee has reviewed the disclosure presented above relating to them.

      significant increases in sales of Viread for HIV, which was approved for sale in the U.S. in October 2001 and the European Union in February 2002.2002 and has since become an antiretroviral therapy widely prescribed by physicians. A significant percentage of Gilead'sour product sales continue to be denominated in foreign currencies. Prior to 2002, we did not hedge our exposure to the impact of fluctuating foreign exchange rates on forecasted sales. EffectiveIn January 2002, we began to use forward contracts to hedge a percentage of our forecasted international sales, which will reduce,primarily those denominated in the Euro currency. This reduces, but does not eliminate, fluctuations in sales due to changes in foreign currency exchange rates, primarily those denominated in the Euro currency.rates. Losses on these revenue hedges reduced product revenues by $2.8 million in 2003 and $1.0 million in 2002.

      Sales of Viread were 68% of total product sales in 2002 were $225.8 million in 2002, or2003, compared to 53% of total product sales compared to $15.6 million, orin 2002 and 8% of total product sales in 2001. Of the Viread sales in 2002, $167.02003, $355.9 million were U.S. sales, an increase of 113% versus 2002, and $58.8$210.6 million were international sales.sales, an increase of 258% versus 2002. With the continued market expansion of Viread, we expect Viread sales in 20032004 to grow approximately double25% to 30% and be in the range of $425$700 million to $475$750 million.


              SalesDuring 2003, we experienced significant fluctuations in U.S. distribution channel inventory levels due to speculative purchasing by the major wholesalers. As a result, we experienced increased quarter to quarter sales volatility from these purchasing patterns. While we have enacted certain policies to reduce this type of AmBisome were $185.7 millionpurchasing and are in 2002, an increase of 13% over AmBisomediscussions with our key wholesalers, we expect to continue to experience sales of $164.5 million in 2001. Sales of AmBisome were $141.1 million in 2000. volatility for the foreseeable future.

      Prior to 2002, our revenues have beenwere primarily derived from sales of AmBisome, which represented 44% of total product sales in 2002 and 86% of total product sales in 2001 and 94% of total product2001. AmBisome sales in 2000.2003 were $21.7 million higher due to the favorable currency environment compared to 2002. On a volume basis, AmBisome sales in Europe decreased by 5% compared to 2002 due to increasing competition. Excluding the impact of foreign currencies relative to the U.S. dollar, AmBisome sales grew 9% for the year ended December 31, 2002 over the comparable period in 2001. The increase in sales in 2002 compared to 2001 was primarily due to volume sales increases in Europe, which offset declining sales in the U.S. The increase in sales in 2001 compared to 2000 is primarily due to volume and price increases in the U.S. and Europe. In addition, excluding the impact of the decline in foreign currencies relative to the U.S. dollar in 2001, sales of AmBisome in 2001 would have increased 20%. With the expected increase in competition, we expect AmBisome sales for 20032004 to be lower than 20022003 and in the range of $160 million to $170$180 million.

      Royalty Revenue

      We recorded royalty revenue of $25.2 million in 2003, compared with $20.4 million in 2002 compared withand $23.0 million in 2001 and $24.6 million in 2000.2001. During this three-year period, the most significant source of royalty revenue was from sales of AmBisome in the U.S. by Fujisawa under a co-promotion arrangement with us. Royalty revenue from Fujisawa was $12.5 million in 2003, compared with $15.7 million in 2002 compared withand $17.1 million in 2001 and $13.5 million in 2000.2001.

      We also recorded royalty revenue of $12.0 million in 2003, $3.4 million in 2002 and $4.5 million in 2001 and $9.6 million in 2000 related to sales of Tamiflu. Tamiflu is an orally administered compound developed to treat and prevent viral influenza in humans. Gilead co-developed Tamiflu with Roche, which owns the worldwide commercial rights to Tamiflu, and is required to pay us a royalty on net sales of the product. We began recognizing royalties from Tamiflu in the first quarter of 2000. In June 2002, Roche received European regulatory approval of Tamiflu for the treatment of influenza in adults and children and prevention in adolescents and adults. As it is difficult to estimate third party product sales, we record royalty revenue one quarter in arrears. Due to this lag in reporting, the royalties related to the severe flu epidemic in the U.S. in the fourth quarter of 2003 will be recorded in the first quarter of 2004.

      Contract Revenue

      Total contract revenue was $6.3 million in 2003, compared with $22.5 million in 2002 compared withand $19.8 million in 2001 and $21.3 million in 2000.2001. In 2002 and 2001 a primary source of contract revenue was from our licensing of the SELEX process patent estate to Archemix, which, due to collectibility concerns, we recognized on aas the cash basis.was received. This provided contract revenue of $8.1 million of contract revenue in 2002 and $8.6 million in 2001. In 2002, Roche made milestone payments of $8.0 million for the European prophylaxis and treatment approvals of Tamiflu, and in 2001 made a $2.0 million milestone payment relating to the development of Tamiflu under an R&D collaboration agreement. In 2000, contract revenue from Roche consisted of $9.6 million in milestone payments related to Roche completing regulatory filings and approvals for Tamiflu in the U.S. and Japan. As of December 31, 2002, Gilead is2003, we are entitled to additional milestone payments of up to $1.6 million upon Roche achieving certain developmental and regulatory milestones.

      In April 2002, Gilead and GSK entered into a licensing agreement providing GSK the rights to commercialize Hepsera Gilead's, our antiviral for the treatment of chronic hepatitis B, in Asia, Latin America and certain other territories. Under the agreement, Gilead retained rights to Hepsera in the U.S., Canada, Eastern and Western Europe, Australia and New Zealand. GSK received exclusive rights to develop Hepsera solely for the treatment of chronic hepatitis B in all of its territories, the most significant of which include China, Korea, Japan and Taiwan. In addition, GSK paid Gileadus an up-front licensing fee of $10.0 million as the first payment against these additional obligations and, may pay up to an additional $30.0 million upon achievement by GSK of certain regulatory, development and commercial milestones. Of this $30.0 million, $2.0 million was received for the U.S. approval of Hepsera in September 2002.2002 and $2.0 million was received for the Canadian approval of Hepsera in August 2003. GSK also will pay Gileadus a royalty on net sales, if any, of Hepsera in the GSK territories. GSK will have full


      responsibility for development and commercialization of Hepsera in GSK'sGSK’s territories. The $10.0 million up-front fee and the $2.0$4.0 million U.S.of approval feemilestone fees have been recorded as deferred revenue in 2002 with a total of $0.9 million and $0.5 million being recognized as contract revenue in 2002.2003 and 2002, respectively. The $12.6 million balance of deferred revenue at December 31, 20022003 will be amortized into contract revenue over the period of Gilead'sour remaining obligations under the agreement, approximately 1412 years.

      In December 2001, we completed the sale of our oncology assets to OSI. To date, we have received $130.0 million in cash and $38.8 million in OSI stock.stock from this sale. Under this agreement, we are entitled to additional payments from OSI of up to $30.0 million in either cash or a combination of cash and OSI stock if and when OSI reaches certain development milestones for NX 211, the most advanced of the oncology product candidates sold to OSI. Under a related manufacturing agreement, we will produce NX 211 and GS 7904L, the two liposomal products included in the sale at our manufacturing facility in San Dimas, California. In 2003 and 2002, we recognized $1.1 million and $3.3 million, respectively, of contract revenue under this manufacturing agreement.

      In October 2001, we entered into an agreement with Archemix Corporation relating to our SELEX technology. Under this agreement, we gave Archemix the exclusive rights to the SELEX process, including therapeutic and other commercial applications to the extent not already licensed under pre-existing agreements. Archemix paid to us $8.5 million in 2002 and $9.0 million in 2001.2001 and recorded the net amounts of $8.1 million and $8.6 million as contract revenue in 2002 and 2001, respectively. As required by our license agreement with ULEHI, we paid 5% of the $8.5 million and $9.0 million payments to ULEHI. We also received a warrant to purchase 350,000 shares of Archemix common stock, the value of which is not material. As required by our license agreement with ULEHI, we transferred 5% of this warrant to ULEHI at that time. We have since transferred the remainder of the warrant to ULEHI.

      In March 2000, we entered into an agreement with EyeTech Pharmaceuticals, Inc. relating to Gilead'sour proprietary aptamer EYE001, currently known as Macugen. Currently in earlyPhase 3 clinical trials, Macugen is an inhibitor of vascular endothelial growth factor, or VEGF, which is known to play a role in the development of certain ophthalmic diseases. Under the terms of the agreement, EyeTech received worldwide rights to all therapeutic uses of Macugen, and, if the product is successfully commercialized, EyeTech will pay us royalties on worldwide sales of the product. EyeTech also will be responsible for all research and development costs. We provided clinical supplies of the product to EyeTech through March 2001. We received a $7.0 million up-front licensing fee from EyeTech in April 2000, which has been recognized as revenue ratably over the one-year supply agreement period. Accordingly, $5.2 million of the license fee was recorded as contract revenue in 2000, and $1.8 million was recognized as revenue in 2001. We are also entitled to additional cash payments from EyeTech of up to $25.0 million if and when EyeTech reaches certain Macugen development milestones. Additionally, we received a warrant to purchase 791,667 shares of EyeTech series B convertible preferred stock, exercisable at a price of $6.00 per share, the price at which the stock was issued to other investors. In January 2004, EyeTech completed its initial public offering. We intend to exercise our warrant for shares of common stock and sell the shares subject to a 180-day lock-up period. The fair value of the warrant has been adjusted in the first quarter of 2004 as a result of the EyeTech public offering.

      Substantially all of the increase from each year to year period can be attributed to increases in the volume of Viread sold, as this product was launched in the U.S. late in the third quarter of 2001.


      Gross Margins

      Product gross margins were 86.5% in 2003, compared with 83.6% in 2002 compared withand 77.1% in 2001 and 77.6% in 2000. 2001. The improvement from 2002 to 2003 and 2001 to 2002 is primarily driven by product mix as Viread, a higher margin product, contributed more significantly to net product sales in 2002, whereas only modest sales of Viread were recordedeach succeeding year.

      Movements in 2001.

              Foreignforeign currency exchange rates also impactsimpact gross margins as we price our products in the currency of the country into which the products are sold while a significant majority of our manufacturing costs are in U.S. Dollars. For example, an increase in the value of these foreign currencies relative to the U.S. Dollar will positively impact gross margins since our manufacturing costs will remain approximately the same while our revenues after being translated into U.S. Dollars, will increase. In 2003 and 2002, gross margins were positively impacted by the weakening U.S. dollar while in 2001, and 2000, gross margins were negatively impacted by these factors, as discussedfactors. Since 2002, forward contracts have been used to hedge a percentage of our forecasted international sales, which can reduce the impact that changes in the product sales section under the caption "Revenues" above.foreign currency exchange rates have on our gross margins. Except for the potential impact of unpredictable and uncontrollable changes in exchange rates relative to the U.S. Dollar and the mix of product sales between Viread, Hepsera and AmBisome, we expect gross margins in 20032004 to remain relatively stable compared to 2002.2003.

      OperatingResearch and Development Expenses

      In 2002,2003, R&D expenses were 35%31% of total costs and expenses.expenses, excluding purchased in-process research and development expense. In total, R&D expenses were $164.9 million in 2003, compared with $134.8 million in 2002 compared withand $185.6 million in 2001 and $132.3 million in 2000.2001. The major components of R&D expenses consist of personnel costs, including salaries and benefits, clinical studies performed by contract research organizations, materials and supplies, and overhead allocations consisting of various support and facilities related costs. Our R&D activities are also separated into three main categories: research, clinical development and pharmaceutical development. Research costs typically consist of preclinical and toxicology work. Clinical development costs include Phase 1,2,1, 2, and 3 clinical trials as well as expanded access programs. Pharmaceutical development costs consist of product formulation and chemical analysis.

      The $30.1 million increase in R&D spending in 2003 versus 2002 was attributable to increased headcount and the clinical trials associated with the development of Emtriva and the co-formulation of Viread and Emtriva. In addition, during 2003, we settled a contractual dispute with a vendor that resulted in reimbursement to us of $13.2 million that was recorded to research and development spending (in thousands):expense. We expect R&D expenses in 2004 to be approximately $200 million to $220 million, or approximately 20% to 30% higher than 2003 expenses, due primarily to costs associated with the development of the fixed-dose combination of Viread and Emtriva.

      The $50.8 million decrease in R&D spending in 2002 compared to 2001 was primarily due to the reduction in expenses associated with the clinical program for Viread, which was approved by the FDA for sale in the U.S. in October 2001, and the elimination of expenses associated with our oncology program as


      a result of the sale of our oncologythat program to OSI in December 2001. 2001. Additionally, in 2001 we recognized as expense $10.6 million of a $13.0 million up-front license fee paid to Cubist Pharmaceuticals related to the European licensing agreement for daptomycin, also known as Cidecin, signed in January 2001. Upon termination of this agreement in September 2002, we recorded $2.0 million was recorded toof R&D expense, which represented the remaining unamortized asset related to the preclinical oral formulation of daptomycin. Excluding the impact of the Triangle acquisition, we expect R&D expenses in 2003 to be approximately $160 million to $180 million, or approximately 20% to 35% higher than 2002 expenses.daptomycin.

              The $53.3 million increase in R&D spending in 2001 versus 2000 was attributable in part to the recognition of $10.6 million of the $13.0 million up-front payment and $5.5 million of clinical milestone

      47



      payments to Cubist under the European licensing agreement for Cidecin. In addition, our expenses associated with the clinical programs for Viread and Hepsera increased by approximately $18.2 million and $13.3 million, respectively, during the year.

              Recent industryIndustry reports indicate that a biopharmaceutical company generally takes 10 to 15 years (an average of 12 years) to research, develop and bring to market as a new prescription medicine in the U.S. These averages are generally consistent with the projects that we develop internally, although our recent product development timelines have been on a more accelerated basis. Drug development in the U.S. is a process that includes several steps defined by the FDA. The process begins with the filing of an IND, which, if successful, allows opportunity for clinical study of the potential new medicine. Clinical development typically involves three phases of study: Phase 1, 2, and 3, and generally accounts for an average of seven years of a drug'sdrug’s total development time. The most significant costs associated with clinical development are the Phase 3 trials as they tend to be the longest and largest studies conducted during the drug development process. We currently have products in development that are in Phase 3 studies. The successful development of our products is highly uncertain. An estimation of completionCompletion dates and R&D expenses can vary significantly for each product and are difficult to predict. Even after successful development and FDA approval of a product, we undertake additional studies to try and expand the product'sproduct’s label and market potential. For a more complete discussion of the risks and uncertainties associated with completing the development of products, see the "Risk“Risk Factors That Affect Gilead"Gilead” section of Item I above.

      The increase in expenses in 2003 compared to 2002 compared with $125.1 million in 2001is primarily due to our global sales and $82.0 million in 2000. marketing efforts, including the expansion of our U.S. and European sales forces and increased infrastructure investments required to support the growth of our business.

      The increase in expenses in 2002 compared to 2001 is primarily due to our global sales and marketing efforts, including the expansion of Gilead'sour U.S. and European sales forces to support the commercial launches of Viread and Hepsera.

              The increase in SG&A expenses in 2001 versus 2000 was primarily due to Gilead's increased global marketing efforts and the expansion of our sales force to support the commercial launch of Viread.

      In 2003,2004, we expect SG&A expenses excluding the impact of the Triangle acquisition, to be approximately $250$310 million to $270$330 million, or 40%25% to 50%30% higher than 20022003 levels, primarily due to the increase in marketing activities associated with the continued promotion of Viread, Emtriva, Hepsera and AmBisome.

      In-process Research and Development

      In connection with the acquisition of the net assets of Triangle completed in January 2003, we recorded in-process research and development expenses of $488.6 million in the first quarter of 2003. The charge was due to Triangle’s incomplete research and development programs that had not yet reached technological feasibility and had no alternative future use as of the acquisition date.

      The remaining efforts for completion of Triangle’s research and development projects primarily consist of clinical trials, the cost, length and success of which are extremely difficult to predict. Numerous risks and uncertainties exist that could prevent completion of development, including the ability to enroll patients in clinical trials, the possibility of unfavorable results of our clinical trials, and the risk of failing to obtain FDA and other regulatory body approvals. Feedback from regulatory authorities or results from


      clinical trials might require modifications or delays in later stage clinical trials or additional trials to be performed. We cannot be certain that emtricitabine for the treatment of chronic hepatitis B, purchased from Triangle, will be approved in the U.S. or the European Union or whether marketing approvals will have significant limitations on its use. We have terminated our rights with respect to the other potential products that we acquired with the acquisition of Triangle. We also do not yet have approval of the fixed-dose combination product containing tenofovir DF and emtricitabine. Future discussions with regulatory agencies will determine the amount of data needed and timelines for review, which may differ materially from current projections. The acquired products under development may never be successfully commercialized. Emtriva, for example, is a product with many similarities to other existing products. As a result, it may be difficult to successfully penetrate the market and to achieve significant revenues. In addition, emtricitabine for the treatment of chronic hepatitis B faces significant uncertainties associated with pricing, efficacy, and the cost to produce that may not be successfully resolved. As a result, we may make a strategic decision to discontinue development of this product, as we did with clevudine and amdoxovir, if we believe commercialization will be difficult relative to other opportunities in our pipeline. If these programs cannot be completed on a timely basis or at all, then our prospects for future revenue growth would be adversely impacted.

      The value of the acquired in-process research and development was determined by estimating the related future net cash flows between 2003 and 2020 using a present value risk adjusted discount rate of 15.75%. This discount rate is a significant assumption and is based on our estimated weighted average cost of capital adjusted upward for the risks associated with the projects acquired. The projected cash flows from the acquired projects were based on estimates of revenues and operating profits related to the projects considering the stage of development of each potential product acquired, the time and resources needed to complete the development and approval of each product, the life of each potential commercialized product and associated risks including the inherent difficulties and uncertainties in developing a drug compound including obtaining FDA and other regulatory approvals, and risks related to the viability of and potential alternative treatments in any future target markets.

      Asset Impairment

      During 2003, we recorded an asset impairment charge of $10.2 million on certain of our long-lived assets, primarily leasehold improvements, manufacturing and laboratory equipment. This non-cash charge was driven by the decision in December 2003 to terminate our liposomal research and development activities in San Dimas and discontinue the DaunoXome product line. The impairment was based on our analysis of the undiscounted cash flows to be generated from the affected assets as compared to their carrying value. As the carrying value exceeded the related estimated undiscounted cash flows, we wrote the carrying value of the long-lived assets down to their estimated fair value.

      Gain on Sale of Oncology Assets

      In December 2001, we completed the sale of our oncology assets, pipeline of clinical stage oncology products and related intellectual property, as well as our Boulder, Colorado operations, including clinical research and drug development personnel, infrastructure and facilities, to OSI. The pipeline of clinical candidates includes NX 211 (liposomal lurtotecan), GS 7836 (a nucleoside analogue) and GS 7904L (a liposomal thymidylate synthase inhibitor). On the closing date, we received $130.0 million in cash and OSI common stock valued at approximately $38.8 million. We recorded a non-operating gain of $157.8 million and income taxes of $3.3 million in the fourth quarter of 2001 as a result of this transaction. In addition, we recorded income taxes of $3.3 million in connection with this transaction.

      Loss on Sale of Marketable Securities

      In July 2002, the Companywe sold all of itsour remaining shares of OSI common stock for approximately $22.0 million. These shares were partial consideration for the sale of our oncology assets to OSI in


      December 2001, at which time they were recorded at a fair market value of approximately $38.0 million. In connection with the sale of these remaining shares, we recognized a non-operating loss of approximately $16.0 million in the year ended December 31, 2002.

      48



      Gain on Sale of Unconsolidated Affiliate

      In August 2001, we also sold our 49 percent interest in Proligo L.L.C. (Proligo) to Degussa Corporation for $14.3 million in cash. Proligo was a joint venture between Gileadus and SKW Americas, Inc. focused on the manufacturing of oligonucleotides. SKW Americas, a subsidiary of Degussa Corporation, held the remaining 51 percent of Proligo. The proceeds, net of Gilead'sour investment in Proligo, are reflected as an $8.8 million gain on the sale of unconsolidated affiliate in 2001.

      Interest and Other Income, and Interest Expensenet

      We recorded interest and other income of $13.0 million in 2003, compared with $22.3 million in 2002 compared withand $25.6 million in 20012001. The decrease in 2003 compared to 2002 is attributable to the significant decline in interest rates and $17.6 million in 2000.a lower average cash balance due to the acquisition of the net assets of Triangle and the purchase of our Foster City campus, partially offset by positive cash flow from operations. The decrease in 2002 compared to 2001 is attributable to the significant decline in interest rates, partially offset by a higher average cash balance due to positive cash flow from operations and to the proceeds from the sale of the oncology assets to OSI. The increase in 2001 over 2000 was due to higher average balances of invested funds. Interest income in 20032004 will depend principally upon prevailing interest rates, over which we have no control and the level of our cash, cash equivalent and marketable securities balances.

      Interest Expense

      We incurred interest expense of $21.9 million in 2003, compared with $13.9 million in 2002 compared withand $14.0 million in 2001 and $4.4 million in 2000.2001. The significant increase in 20012003 over 20002002 is due to the full year of interest on our $250.0$345.0 million 5%2% convertible subordinated notes.senior notes, issued in December 2002. Interest expense for 20002002 and 2001 consisted primarily of interest on the $79.5$250.0 million 6.25%5.0% convertible subordinated notes, which were converted to common stock in August 2000.December 2003. We expect interest expense in 20032004 to increasedecrease as compared with 2002 expense levels2003 primarily due to the issuanceredemption of the $345.0$250.0 million 2%5% convertible seniorsubordinated notes in December 2002.2003.

      Provision for (Benefit from) Income Taxes

      Our provision for (benefit from) income taxes was ($95.5) million, $1.3 million and $4.1 million in 2003, 2002 and $1.2 million2001, respectively. The benefit in 2002, 20012003 includes the reversal of our valuation allowance against certain of our deferred tax assets. In December of 2003, we concluded that it was more likely than not that we would realize a portion of the benefit related to our deferred tax assets. Accordingly, we reduced the valuation allowance against the assets and 2000, respectively. Thisrecorded a tax benefit of $111.6 million. The recognition of these deferred tax assets has no impact on our current period cash flows. The recognition of these deferred tax assets increased reported earnings per share due to the resulting benefit recorded in the statement of operations from the reduction in our valuation allowance. Partially offsetting the tax benefit recorded is income tax expense associated with income earned by our foreign subsidiaries, foreign losses at lower rates and the non-tax deductibility of the purchased in-process research and development charge. We had significant net operating losses reducing our U.S. liability. Excluding the benefit relating to the reversal of our valuation allowance, and the write off of purchased in-process research and development, our effective tax rate for 2003 was 5%. For 2004, we expect our effective tax rate to be in the 32% to 35% range for the full year, reflecting a more normalized tax rate going forward.

      45



      The income tax expense in 2002 and 2001 was primarily associated with income earned by our foreign subsidiaries as we havehad significant net operating losses, which reducereduced our U.S. tax liability. The significant increaseincreases in income tax expense in 2001 resulted principally from the gain on the sale of our oncology assets to OSI, for which we recorded approximately $3.3 million of federal and state alternative minimum taxes. The provision for 2002 was reduced by a change in the U.S. income tax law. This law allowsallowed net operating loss carryforward deductions to offset 100% of alternative minimum taxable income, resulting in a reduction of U.S. income tax recorded in the previous years of $1.3 million.

              We record a valuation allowance to reduce our deferred tax assets to the amount that is likely to be realized. We consider future taxable income, ongoing tax planning strategies and our historical financial performance in assessing the need for a valuation allowance. If it were determined that we would be able to realize all or part of our deferred tax assets in the future, an adjustment to the deferred tax asset would increase income in the period in which such determination was made. Likewise, if we determine that we would not be able to realize all or part of our deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period in which such determination was made. We evaluate the realizibility of our deferred tax assets on a quarterly basis.

      Equity in Loss of Unconsolidated Affiliate

      In 2001, we recorded $2.1 million as our equity in the loss of our unconsolidated affiliate, Proligo, prior to the date of the sale ofProligo. We sold our 49 percent interest. In 2000, we recorded $2.9 million as our equityinterest in the loss of Proligo. This represented our 49 percent share of Proligo's loss for the thirteen-month period ended December 31, 2000. During the fourth quarter of 2000, Proligo changed its fiscal year-end to December 31 from November 30.August 2001.

      Cumulative Effect of Change in Accounting Principle

      In the year ended December 31, 2001, Gileadwe adopted SFAS 133,Accounting for Derivative Instruments and Hedging Activities, which resulted in a cumulative effect of change in accounting principle of $1.1 million. In the year ended December 31, 2000, Gilead adopted the Securities and Exchange Commission's Staff Accounting Bulletin No. 101,Revenue Recognition in Financial Statements, resulting in a cumulative effect of change in accounting principle of ($13.7) million. See NotesNote 2 and 3 to the consolidated financial statements for further discussion.

      Liquidity and Capital Resources

              During the fourth quarter of 2002, a misclassification was discovered in the December 31, 2001 balance sheet and cash flow statement for the year then ended. At December 31, 2001, $38.8 million of OSI stock received in consideration for the divestiture of our oncology assets was misclassified on the balance sheet as cash and cash equivalents instead of as marketable securities. The misclassification had no impact on our statement of operations for any period, including revenues and net income. The December 31, 2001 consolidated balance sheet and 2001 consolidated statement of cash flows in this report have been changed to reflect the correct classification.

      Cash, cash equivalents and marketable securities totaled $707.0 million at December 31, 2003, down from $942.4 million at December 31, 2002, up from $582.9 million at December 31, 2001.2002. The increasedecrease of $359.5$235.4 million was primarily due to the $336.6acquisition of Triangle, for which the net cash impact was $375.5 million, in net proceeds received fromand the issuancepurchase of convertible senior notes in December 2002.our Foster City campus for $123.0 million. Other major sources and uses of cash included net cash provided by operations of $74.4$234.6 million and proceeds from issuances of stock under employee stock plans of $51.4$83.8 million, partially offset by additional capital expenditures of $17.6 million and a $50.0 million convertible note received from Triangle. The $50.0 million loan to Triangle was returned to us in connection with the now completed acquisition. In January 2003, approximately $463.1 million has been paid to complete the acquisition of Triangle.$38.6 million.

      Working capital at December 31, 20022003 was $1,078.9$1,080.0 million compared to $627.6$1,078.9 million at December 31, 2001.2002. Significant changes in working capital during 20022003 included a $43.9$97.1 million increase in accounts receivable, and a $12.3$46.5 million increase in inventory.inventory and a $197.6 million increase in current deferred tax assets. The accounts receivable increase was primarily due to increased sales of Viread in the U.S. and Europe. The $12.3$46.5 million increase in inventory was primarily due to an increase in the purchase of raw materials and the production of Viread inventory to meet increasing sales demand. The $197.6 million increase in current deferred tax assets was due to the reversal of the valuation allowance against certain of our net deferred tax assets. The $6.1 million increase in accounts payable is primarily due to increases in our raw material purchases in support of Viread sales growth.

      Significant changes in current liabilities during 20022003 included an $11.5a $44.5 million increase in accrued liabilities. The significant components of the $44.5 million increase in accrued liabilities, an $8.9exclusive of the assumed liabilities associated with the acquisition of the net assets of Triangle, consist of a $44.2 million increase in other accrued liabilities and a $6.2 million increase in accrued compensation and employee benefits, partially offset by a $5.9 million decrease in accrued clinical and preclinical expenses, a $6.8expenses. The $44.2 million increase in accrued compensation, a $5.2 million increase in accounts payable and a $13.1 million increase in deferred revenue. The $11.5 million increase inother accrued liabilities is primarily due to Medicaid rebate obligations associated with higher sales of Viread.Viread, an increase in our income taxes payable and an increase in the recorded liability associated with the fair value of our forward currency contracts. The $8.9$6.2 million increase in accrued compensation is primarily due to increased bonus accruals and the expansion of our sales force. The $5.9 million decrease in accrued clinical and preclinical expenses is primarily due to decreasing activity associated with the clinical trial programs for Viread and Hepsera. The $6.8 million increase in accrued compensation is primarily due

      In addition to increased bonus accruals and the expansionpurchase of our sales force. The $5.2 million increase in accounts payable is primarily due to increases in our raw material purchases in support of Viread sales growth. The $13.1 million increase in deferred revenue primarily relates to the $12.0 million received under the collaboration with GSK thatFoster City campus, we entered into in April 2002.

              The $13.4 million effect of exchange rate changes on cash is primarily due to the weakening U.S. dollar relative to the Euro and the translation of our foreign subsidiaries' accounts receivable balances, which are primarily denominated in the Euro currency.

              We made capital expenditures of $38.6 million in 2003, compared to $17.6 million in 2002 and $26.3 million in 2001 and $15.6 million in 2000.2001. These expenditures were primarily for facilities improvements to accommodate our growth, as well as for laboratory and manufacturing


      equipment. Capital expenditures related to research and development were between 50% and 60% of the $38.6 million spent in 2003, 20% to 25% of the $17.6 million spent in 2002 and 50% to 60% of the

We expect our capital spending for 20032004 to be significantly higher than 2002 levels$55.0 million to $65.0 million due to increased infrastructure needs and higher R&D spending.spending associated with the pilot plant we are constructing at our Foster City facilities.

      In December 2002, we issued $345.0 million of 2% convertible senior notes due December 15, 2007 in a private offering. The notes are currently convertible into a total of up to 7,340,425 shares of Gilead common stock at $47.00 per share. The $47.00 conversion price was higher than Gilead'sGilead’s common stock price at the notes'notes’ issuance date. The notes are redeemable in whole or in part, at our option, at any time on or after June 19, 2004, at specified redemption prices plus accrued interest. Debt issuance costs of $8.4 million incurred in connection with the issuance of the notes were recorded as other noncurrent assets, and are being amortized to interest expense on a straight-line basis over the contractual term of the notes.

      In December 2000, we issued $250.0 million of 5% convertible subordinated notes due December 15, 2007 in a private offering. The notes are currentlywere convertible into a total of up to 10,178,116 shares of Gilead common stock at $24.5625 per share. The $24.5625 conversion price was higher than Gilead'sGilead’s common stock price at the notes'notes’ issuance date.

              In August 2000, we redeemed our 6.25%5% convertible subordinated debentures at a cash price of $1,030 per $1,000 principal amount of debentures outstanding, plus accrued interest, which was thenotes for redemption price provided for in the original debenture indenture. Upon redemption, the entire $79.5 million in principal amount of the debentures outstanding at that time wasNovember 2003 and converted into 7,135,156 newly issued shares ofthem to Gilead common stock by August 15, 2000.

      We believe that our existing capital resources, supplemented by cash generated from our operations, will be adequate to satisfy our capital needs for the foreseeable future. Our future capital requirements will depend on many factors, including:

        ·the commercial performance of Viread, Hepseraour current and AmBisome,

        future products,

        ·the commercial performance of any of our other products in development that receive marketing approval, including emtricitabine from our acquisition of Triangle completed in January 2003,

        the success of our partners' research, developmentprogress and commercialization efforts for the products they have partnered with us,

          ·       the possibility of acquiring other companies or new products, and

          ·the establishment of additional collaborative relationships with other companies.

        We may in the future require additional funding, which could be in the form of proceeds from equity or debt financings, such as from our universal shelf registration filing in December 2003 for the potential issuance of up to $500.0 million of our securities, or additional collaborative agreements with corporate partners. If such funding is required, we cannot assure you that it will be available on favorable terms, if at all.

        Subsidiaries and Other

        We have established a variety of subsidiaries in various countries for the purpose of conducting business in those locations. All of these subsidiaries are consolidated in our financial statements. We do not have any "special purpose"“special purpose” entities that are unconsolidated in our financial statements, including those defined as "variable interest entities" by the Financial Accounting Standards Board (FASB) Interpretation No. 46,Consolidation of Variable Interest Entities.statements. We are also


        not involved in any non-exchange traded commodity contracts accounted for at fair value. We have no commercial commitments with related parties, except for employee loans.

        Contractual Obligations

        We have contractual obligations in the form of capital and operating leases, notes payable, raw material supply arrangements and clinical research organization contracts.

        (1)            At December 31, 2003, we had firm capital project commitments of approximately $15.7 million, related to our chemical development pilot plant currently under construction at our Foster City facility. Our budgeted capital expenditures for 2004 are significantly higher and we anticipate increasing our capital spending in future years.

        (2)            At December 31, 2003, we had firm commitments to purchase inventory-related materials. The amounts disclosed only represent minimum purchase requirements. Actual purchases may differ significantly from these amounts.

        (3)            At December 31, 2003, we had several clinical studies in various clinical trial phases. Our most significant expenditures are to contract research organizations. Although most contracts are cancelable, we generally have not cancelled contracts. These amounts reflect commitments based on existing contracts and do not reflect any future modifications to existing contracts and anticipated or potential new contracts.

        Recent Accounting Pronouncements

        In June 2002,January 2003, the FASB issued SFASFASB Interpretation No. 146,46 (FIN 46), Consolidation of VariableAccountingInterest Entities, an Interpretation of ARB No. 51. FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for Costs Associated with Exit or Disposal Activities. SFAS 146 requires that a liability for costs associated with an exit or disposal activity be recognized and measured initially at fair value only when the liability is incurred. SFAS 146entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective immediately for exitall new variable interest entities created or disposal activities that are initiatedacquired after DecemberJanuary 31, 2002.2003. We did not create or acquire any new variable interest entities after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46, as amended, must be applied at the end of the first interim or annual period ending after March 15, 2003. The adoption of SFAS 146 is not expected to have a material impact on our financial position and results of operations.

                In November 2002, The EITF reached a consensus on Issue 00-21, addressing how to account for arrangements that involve the delivery or performance of multiple products, services, and/or rights to use assets. Revenue arrangements with multiple deliverables are divided into separate units of accounting if the deliverables in the arrangement meet the following criteria: (1) the delivered item has value to the customer on a standalone basis; (2) there is objective and reliable evidence of the fair value of undelivered items; and (3) delivery of any undelivered item is probable. Arrangement consideration should be allocated among the separate units of accounting based on their relative fair values, with the amount allocated to the delivered item being limited to the amount that is not contingent on the delivery of additional items or meeting other specified performance conditions. The final consensus will be applicable to agreements entered into in fiscal periods beginning after June 15, 2003 with early adoption permitted. We are reviewing the provisions of this consensus to determine the effect, if any, it may have on the Company's financial position and results of operations.

                In November 2002, the FASB issued Interpretation No. 45 (or FIN 45),Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. FIN 45 elaborates on the existing disclosure requirements for most guarantees, including residual value guarantees issued in conjunction with operating lease agreements. It also clarifies that at the time a company issues a guarantee, the company must recognize an initial liability for the fair value of the obligation it assumes under that guarantee and must disclose that information in its interim and annual financial statements. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002. Our adoption of the disclosure provisions of FIN 4546 did not have a material impact on our results of operations andconsolidated financial position.statements.

                In December 2002, the FASB issued SFAS No. 148,Accounting for Stock-Based Compensation-Transition and Disclosure. SFAS 148 is an amendment to SFAS No. 123,Accounting for Stock-Based

        52



        Compensation issued in October 1995. SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based compensation. In addition, this Statement amends the disclosure requirements of Statement 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The additional disclosure requirements of SFAS 148 are effective for fiscal years ending after December 15, 2002. We have elected to continue to follow the intrinsic value method of accounting as prescribed by Accounting Principles Board Opinion No. 25 (or APB 25),Accounting for Stock Issued to Employees, to account for employee stock options.


        ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Foreign Currency Exchange Risk

        Our operations include manufacturing and sales activities in the U.S. as well as sales activities in Europe and Australia. As a result, our financial results could be significantly affected by factors such as changes in foreign currency exchange rates or weak economic conditions in the foreign markets in which we distribute our products. Our operating results are exposed to changes in exchange rates between the U.S. dollar and various foreign currencies, the most significant of which are the Euro, the British pound and the Australian dollar. When the U.S. dollar strengthens against these currencies, the relative value of sales made in the respective foreign currency decreases. Conversely, when the U.S. dollar weakens, the relative amounts of such sales increase. Overall, we are a net receiver of foreign currencies and, therefore, benefit from a weaker U.S. dollar and are adversely affected by a stronger U.S. dollar relative to those foreign currencies in which we transact significant amounts of business.

        To mitigate the impact of changes in currency exchange rates on cash flows from our foreign currency sales transactions, we enter into foreign exchange forward contracts to hedge our foreign currency-denominated accounts receivable. Additionally, to mitigate the impact of currency rate fluctuations on our cash outflows for certain foreign currency-denominated raw materials purchases, we enter into foreign exchange forward contracts to hedge our foreign currency-denominated accounts payable.

        A significant percentage of our product sales is denominated in foreign currencies. Increases in the value of the U.S. dollar against these foreign currencies in the past have reduced, and in the future may reduce, our U.S. dollar return on these sales and negatively impact our financial condition. Prior to 2002, we did not hedge our exposure to the impact of fluctuating foreign exchange rates on forecasted sales. EffectiveIn January 2002, we have begunbegan to use forward contracts to hedge a percentage of our forecasted international sales, primarily those denominated in the Euro currency.

        The following table summarizes the notional amounts, average currency exchange rates and fair values of our open foreign exchange forward contracts at December 31, 2002. The2003. All contracts have maturities of one year or less with one exception.

The significant increase in outstanding contracts from 2002 compares with a total notional amount ofto 2003 can be attributed to our decision to expand the time horizon that we include from three months to twelve months when hedging our forecasted international sales. This decision was made due to the growth in our international business and the increasing fluctuations in exchange rates, primarily the Euro.

        Interest Rate Risk

        Our portfolio of available-for-sale investment securities and our fixed-rate liabilities create an exposure to interest rate risk. With respect to the investment portfolio, we adhere to an investment policy that requires us to limit amounts invested in securities based on duration, industry group, investment type


        and issuer, except for securities issued by the U.S. government. The goals of our investment policy, in order of priority, are as follows:

          ·Safety and preservation of principal and diversification of risk;

        International Credit Risk

        Our accounts receivable balance at December 31, 20022003 was $125.0$235.2 million compared to $74.2$125.0 million at December 31, 2001.2002. The growth was primarily due to higher product sales for Viread in the U.S. and Europe. In certain countries where payments are typically slow, primarily Greece, Spain, Portugal and Italy, our accounts receivable balances are significant. In most cases, these slow payment practices reflect the pace at which governmental entities reimburse our customers. This, in turn, may increase the financial risk related to certain of our customers. Sales to customers in countries that tend to be relatively slow paying have in the past increased, and in the future may further increase,

        the average length of time that accounts receivable are outstanding. At December 31, 2002,2003, our past due accounts receivable for Greece, Spain, Portugal and Italy totaled approximately $49.7$102.7 million, of which approximately $26.6$59.0 million was more than 120 days past due. At December 31, 2001,2002, past due receivables for these countries were $28.7$49.7 million, of which approximately $9.9$26.6 million was more than 120 days past due. To date, we have not experienced significant losses with respect to the collection of our accounts receivable and we believe that all accounts receivable balances as reflected on the consolidated balance sheet, including those due from customers in these four countries, are collectible. We continually seek to improveperform credit evaluations of our collection processes to ensure that we fully collect amounts due to us based on our product salescustomer’s financial condition and that collections are timely.generally have not required collateral.

                There have been no significant changes in our internal controls or in other factors that could significantly affect those controls subsequent to the date of their last evaluation.

        REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

        The Board of Directors and Stockholders
        Gilead Sciences, Inc.

        We have audited the accompanying consolidated balance sheets of Gilead Sciences, Inc. as of December 31, 20022003 and 2001,2002, and the related consolidated statements of operations, stockholders'stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2002.2003. Our audits also included the financial statement schedule listed at Item 15(a) of this Annual Report on Form 10-K. These financial statements and schedule are the responsibility of the management of Gilead Sciences, Inc. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We did not audit the financial statements of Proligo L.L.C., a limited liability company, the investment in which is reflected in the accompanying consolidated financial statements using the equity method of accounting. The Company's equity in the net loss of Proligo L.L.C. was $2,858,000 in 2000. The 2000 financial statements of Proligo L.L.C. were audited by other auditors whose report has been furnished to us and our opinion, insofar as it relates to amounts included for Proligo L.L.C., is based solely on the report of the other auditors.

        We conducted our audits in accordance with auditing standards generally accepted in the 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 and the report of other auditors provide a reasonable basis for our opinion.

        In our opinion, based on our audits and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Gilead Sciences, Inc. at December 31, 20022003 and 2001,2002, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2002,2003, in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedule, referred to above, 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 NotesNote 2 and 3 to the consolidated financial statements, effective January 1, 2001, the Company changed its method of accounting for derivative instruments and hedging activities, and, effective January 1, 2000, changed its method of accounting for non-refundable up-front fees received in connection with collaboration agreements.activities.

        NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        DECEMBER 31, 2002
        2003

        1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Overview

        Gilead (the Company) was incorporated in Delaware on June 22, 1987. We are a biopharmaceutical company focused onthat discovers, develops and commercializes therapeutics to advance the discovery, development and commercializationcare of antivirals, antibacterials and antifungals to treatpatients suffering from life-threatening infectious diseases. We are a multinational company, with revenues from six approved products and marketing operations in ten countries. We focus our research and clinical programs on anti-infectives. Currently, we market Viread (tenofovir disoproxil fumarate) and Emtriva (emtricitabine) for the treatment of HIV infection; Hepsera (adefovir dipivoxil) for the treatment of chronic hepatitis B infection; AmBisome (amphotericin B liposome for injection), an antifungal agent; DaunoXome, a drug approved for the treatment of Kaposi's Sarcoma; and Vistide (cidofovir injection) for the treatment of CMV retinitis. Roche markets Tamiflu (oseltamivir phosphate) for the treatment of influenza, under a royalty paying collaborative agreement with us. We are seeking to add to our existing portfolio of products through our internal discovery and clinical development programs internal discovery programs and through an active product acquisition and in-licensing strategy, such as our acquisition of the net assets of Triangle Pharmaceuticals, Inc. completed in January 2003. Our internal discovery activities include identification of new molecular targets, target screening and medicinal chemistry. In addition, we are currently developing clinical stage products to treat HIV infection. We also have expertise in liposomal drug delivery technology that we use to develop drugs that are safer, easier for patients to tolerateinfection and more effective.chronic hepatitis B.

        The accompanying consolidated financial statements include the accounts of Gilead and its wholly and majority-owned subsidiaries. Significant intercompany transactions have been eliminated. Certain prior period amounts including certain cash and cash equivalents and marketable securities, have been reclassified to be consistent with the current year presentation.

        Stock Split

        On February 22, 2001 and on March 8, 2002, Gilead completed two-for-one stock splits, effected in the form of a stock dividend, to stockholders of record as of February 2, 2001 and February 14, 2002, respectively. Accordingly, all share and per share amounts for all periods presented reflect both of these splits.

        ChangesChange in Accounting PrinciplesPrinciple

        Gilead adopted Statement of Financial Accounting Standards (SFAS) Nos. 133 and 138, collectively referred to as SFAS 133,Accounting for Derivative Instruments and Hedging Activities,in the first quarter of 2001. The change was accounted for as a change in accounting principle. See Note 3. Effective in the first quarter of 2000, Gilead adopted the SEC's Staff Accounting Bulletin No. 101 (SAB 101),Revenue Recognition in Financial Statements, and the change was also accounted for as a change in accounting principle. See Note 2.

        Critical Accounting Policies, Estimates and EstimatesJudgments

        The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of assets and liabilities. On an on-going basis, management evaluates its estimates, including those related to revenue recognition, bad debts, inventories, income taxes, accrued clinical and preclinical expenses, and contingencies. We base our estimates on historical experience and on various other market specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making

        70



        judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates.

        1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Revenue Recognition

        We recognize revenue from product sales when there is persuasive evidence an arrangement exists, delivery to the customer has occurred, the price is fixed or determinable and collectibility is reasonably assured. We do not provide our customers with a general right of product return. However, we will accept returns of productproducts in the U.S. that hashave expired for one year after their expiration, or isproducts that are deemed to be damaged or defective when delivered. Provisionsreceived by the customer. Upon recognition of revenue from product sales, provisions are made for estimated productexpected returns of expired products, government reimbursements and customer incentives, such as cash discounts for prompt payment. Estimates for government reimbursements and governmentcash discounts and rebatesare based on contractual terms and expectations regarding the utilization rates for these programs. Estimates for product returns, including new products, are based on an on-going analysis of industry and historical return patterns, as well as the purchase of third party data to assist the Company in monitoring channel inventory levels and subsequent prescriptions.

        Contract revenue for research and development is recorded as earnedperformance occurs and the earnings process is completed based on the performance requirements of the contract. Nonrefundable contract fees for which no further performance obligations exist, and there is no continuing involvement by Gilead, are recognized on the earlier of when the payments are received or when collection is assured.

        Revenue from non-refundable up-front license fees and milestone payments where we continue involvement through development collaboration or an obligation to supply product, is recognized as performance occurs and performance obligations are completed. In accordance with the specific terms of Gilead’s obligations under the contract, revenue is recognized as the manufacturing obligation is fulfilled or ratably over the development period or the period of the manufacturing obligation, as appropriate.

        Revenue associated with substantive performance milestones is recognized based upon the achievement of the milestones on completion of all performance requirements, as defined in the respective agreements. Revenue under research and development cost reimbursement contracts is recognized as the related costs are incurred.

        Advance payments received in excess of amounts earned are classified as deferred revenue.

        Royalty revenue from sales of AmBisome is recognized in the month following that in which the corresponding sales occur. Royalty revenue from sales of Vistide and Tamiflu is recognized when received, which is the quarter following the quarter in which the corresponding sales occur.

        Shipping and Handling Costs

        Shipping and handling costs incurred for inventory purchases and product shipments are recorded in "Cost“Cost of goods sold"sold” in the Consolidated Statements of Operations.

        Research and Development Expenses

        Major components of R&D expenses consist of personnel costs, including salaries and benefits, clinical studies performed by contract research organizations (CRO’s), materials and supplies, and overhead allocations consisting of various administrative and facilities related costs. Our research and development activities are also separated into three main categories: research, clinical development and

        We record accruals for estimatedcharge clinical and preclinical study costs.costs to expense when incurred, consistent with SFAS No. 2, Accounting for Research and Development Costs. These costs are a significant component of R&D expenses. Management accruesMost of our clinical and preclinical studies are performed by third party CRO’s.

        organizations based on estimates that typically 25% to 30% of the work is for up-front costs with the remaining activity generally incurredCRO’s on a straight-line basis over the life ofservice periods specified in the individual contract or study. This estimate may or may not match the actual services performed by the organizations, which is determined by patient enrollment levels and related activities. We monitor patient enrollment levels and related activity to the extent possible,contracts and adjust our estimates, if required, based upon our on-going review of the level of effort actually incurred by the CRO. Initially we estimate that the work performed under the contracts occurs ratably over the service periods to the expected milestone, event or total contract completion date. The expected completion dates are estimated based upon the terms of the contracts and past experience with similar contracts. We monitor levels of performance under each contract including the extent of patient enrollment and other activities through communications with our CRO’s, and we adjust our estimates, if required, on a quarterly basis so that our expenses reflect the actual effort incurred by each CRO.

        All of our material CRO contracts are terminable by us upon written notice and Gilead is generally only liable for actual effort expended by the CRO at any point in line with actual activity incurred on an on-going basis.time during the contract, regardless of payment status. Amounts paid in advance of services being performed will be refunded if a contract is terminated. Some contracts include additional termination payments that become due and payable only if Gilead terminates the contract. Such additional termination payments are only recorded to expense if the contract is terminated.

        Advertising Expenses

        We expense the costs of advertising, including promotional expenses, as incurred. Advertising expenses were $43.4 million in 2003, $39.3 million in 2002, and $16.5 million in 2001, and $8.4 million in 2000.2001.

        Stock-Based Compensation

        In accordance with the provisions of SFAS No. 123,Accounting For Stock-Based Compensation, as amended by SFAS No. 148 Accounting for Stock-Based Compensation—Transition and Disclosure (SFAS 123), the Company has we have elected to continue to follow Accounting Principles Board Opinion (APB) No. 25,Accounting For Stock Issued To Employees, and Interpretation No. 44 (FIN 44),Accounting for Certain Transactions Involving Stock Compensation—an Interpretation of APB Opinion No. 25, in accounting for itsour employee stock option plans. Under APB 25, if the exercise price of Gilead'sGilead’s employee and director stock options equals or exceeds the fair value of the underlying stock on the date of grant, no compensation expense is recognized.

        1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Fair values of awards granted under the stock option plans and ESPP were estimated at grant or purchase dates using a Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. We used the multiple option approach and the following assumptions:

        Through the end of the third quarter of 2003, the fair value of stock awards granted in 2003 was determined utilizing a volatility rate of 80%. In the fourth quarter of 2003, we changed the volatility assumption we used to arrive at a fair value for our stock awards from 80% to 52%. The most recent two-year time period was used for purposes of calculating the expected volatility. After considering such factors as our stage of development, the length of time that we have been a public company and several drug approvals over the past few years which have enabled us to achieve positive cash flow from operations, we believe this volatility rate better reflects the expected volatility of our stock going forward. The 78% volatility used in the table above represents the weighted average volatility of 80% for the first three quarters and 52% for the fourth quarter.

        The weighted average estimated fair value of ESPP shares purchased was $19.63 for 2003, $18.54 for 2002 and $11.57 for 2001 and $6.06 for 2000.2001.

        Per Share Computations

        For 2003, both basic and diluted net loss per common share are computed based on the weighted average number of common shares outstanding during the period. The potential common shares from convertible notes of 17.2 million shares and outstanding stock options and warrants of 9.9 million shares were excluded from the computation of diluted net loss per share in 2003, as their effect would be antidilutive. For 2002 and 2001, basic net income per common share is computed based on the weighted average number of common shares outstanding during the period. Diluted net income per common share for 2002 includes the effects of approximately 10.9 million stock options but does not include the effect of the $250.0 million 5% convertible notes, which would convert to approximately 10.2 million shares, or the $345.0

        $345.0 million 2% convertible notes, which would convert to approximately 7.3 million shares, as the effect of their assumed conversion is antidilutive. Diluted net income per common share for 2001 includes the effects of approximately 12.1 million stock options and warrants, but does not include the effect of the $250.0 million 5% convertible notes which would convert to approximately 10.2 million shares, as the effect of their assumed conversion is antidilutive. For 2000, both basic and diluted loss per common share are computed based on the weighted average number of common shares outstanding during the period. The potential common shares from convertible notes, stock options and warrants, as well as the convertible debentures that were previously outstanding, were excluded from the computation of diluted loss per share in 2000, as their effect would be antidilutive.

        Cash and Cash Equivalents

        We consider highly liquid investments with insignificant interest rate risk and a remaining maturity of three months or less at the purchase date to be cash equivalents. We may enter into overnight repurchase agreements under which we purchase securities with an obligation to resell them the following day. Securities purchased under agreements to resell are recorded at face value and reported as cash and cash equivalents. Under our investment policy, we may enter into repurchase agreements (repos) with major banks and authorized dealers provided that such repos are collateralized by U.S. government securities with a fair value of at least 102% of the fair value of securities sold to Gilead. Other eligible investments under our investment policy include commercial paper, money market funds and other bank obligations.

                During the fourth quarter of 2002, a misclassification was discovered in the previously reported December 31, 2001 balance sheet and cash flow statement. At December 31, 2001, $38.8 million of OSI stock received in consideration for the divestiture of our oncology assets was misclassified on the balance sheet as cash and cash equivalents instead of as marketable securities. The December 31, 2001 consolidated balance sheet and 2001 consolidated statement of cash flows in this report have been changed to reflect the correct classification.

        Marketable Securities

                Management determinesWe determine the appropriate classification of our marketable securities, which consists solely of debt securities, at the time of purchase and reevaluatesreevaluate such designation at each balance sheet date. All of our marketable securities are classified as available-for-sale and carried at estimated fair values and reported in either cash equivalents or marketable securities. At December 31, 2002,2003, cash and cash equivalents include $559.8$116.0 million of securities designated as available-for-sale ($82.3559.8 million at December 31, 2001)2002). Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported as a separate component of stockholders'stockholders’ equity. Interest income includes interest, dividends, amortization of purchase premiums and discounts, and realized gains and losses on sales of securities. The cost of securities sold is based on the specific identification method. We regularly review all of our investments for other-than-temporary declines in fair value. When we determine that the decline in fair value of an investment below our accounting basis is other-than-temporary, we reduce the carrying value of the securities we hold and record a loss in the amount of any such decline. No such reductions have been required during the past three years.

        Concentrations of Credit Risk

                Gilead isWe are subject to credit risk from itsour portfolio of cash equivalents and marketable securities. By policy, we limit amounts invested in such securities by duration, industry group, investment type and issuer, except for securities issued by the U.S. government. Gilead isWe are not exposed to any significant concentrations of credit risk from these financial instruments. The goals of our investment policy, in order of priority, are as follows: safety and preservation of principal and diversification of risk; liquidity of investments sufficient to meet cash flow requirements; and competitive after-tax rate of return.

        sales by our European subsidiaries and export sales to our distributors in Europe. In certain countries where payments are typically slow, primarily Greece, Spain, Portugal and Italy, our accounts receivable balances are significant. In most cases, these slow payment practices reflect the pace at which governmental entities reimburse our customers. This, in turn, may increase the financial risk related to certain of our customers. Sales to customers in countries that tend to be relatively slow paying have in the past increased, and in the future may further increase, the average length of time that accounts receivable are outstanding. At December 31, 2002,2003, our past due accounts receivable for Greece, Spain, Portugal and Italy totaled approximately $49.7$102.7 million, of which approximately $26.6$59.0 million was more than 120 days past due.due based on the contractual terms of the receivables. At December 31, 2001,2002, past due receivables for these countries were $28.7$49.7 million, of which approximately $9.9$26.6 million was more than 120 days past due.

        receivable and believe that all our past due accounts receivable as reflected in the consolidated balance sheet, including those due from customers in these four countries, are collectible. We perform credit evaluations of our customer'scustomer’s financial condition and generally have not required collateral.

        Many of the materials that we utilize in our operations are made at only one facility. For example, we depend on single suppliers for high quality amphotericin B, daunorubicin HCl, distearoylphosphatidylcholine and high quality cholesterol, each of which is used in the manufacture of one or more of our liposomal products.AmBisome. If supplies from our suppliers were interrupted for any reason, we may be unable to ship Viread, AmBisome, Hepsera, VistideEmtriva or DaunoXome,Vistide, or to supply any of our products in development for clinical trials.

                As of December 31, 2002, we had a $50.0 million note receivable from Triangle Pharmaceuticals, Inc. incurred in conjunction with the acquisition completed in January 2003. This note was not included in cash, cash equivalents, and marketable securities and has subsequently been eliminated in consolidation as a result of the closing of the acquisition on January 23, 2003.

        Inventories

        Inventories are recorded at the lower of cost or market, with cost determined on a first-in, first-out basis. ManagementWe periodically reviewsreview the composition of inventory in order to identify obsolete, slow-moving or otherwise unsaleable items. If such items are observed and there are no alternate uses for the inventory, we will record a write-down to net realizable value in the period that the units are identified as impaired. Historically, inventory write-downs have been insignificant and consistent with management'smanagement’s expectations.

        Property, Plant and Equipment

          Long-Lived Assets

        The carrying value of long-lived assets is reviewed on a regular basis for the existence of facts or circumstances both internally and externally that may suggest impairment. Specific potential indicators of impairment include:

          ·a significant decrease in the fair value of an asset;

          ·a significant change in the extent or manner in which an asset is used or a significant physical change in an asset;

          ·a significant adverse change in legal factors or in the business climate that affects the value of an asset;

          ·an adverse action or assessment by the U.S. Food and Drug Administration or another regulator;

          ·an accumulation of costs significantly in excess of the amount originally expected to acquire or construct an asset; and

          ·operating or cash flow losses combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with an income-producing asset.


        Should there be an indication of impairment, we will confirm thistest for recoverability by comparing the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition to the carrying amount of the asset. In estimating these future cash flows, assets and liabilities are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other assetsuch groups. If the sum of the expectedundiscounted future cash flows (undiscounted and without interest changes) isare less than the carrying amount of the asset, an impairment loss, measured as the excess of the carrying value of the asset over its fair value, will be recognized. The cash flow estimates used in such calculations are based on management'smanagement’s best estimates, using appropriate and customary assumptions and projections at the time.

        Foreign Currency Translation, Transactions and Contracts

        Adjustments resulting from translating the financial statements of our foreign subsidiaries into U.S. dollars are excluded from the determination of net income and are accumulated in a separate component of stockholders'stockholders’ equity. Net foreign exchange transaction gains (losses) are reported as a selling, general and administrative expenseexpenses in the consolidated statements of operations. Such realized gains (losses) were ($2.2) million in 2003, $0.6 million in 2002 and ($1.4) million in 2001 and ($0.5) million in 2000.2001.

        We hedge certain of our foreign currency exposures related to outstanding trade accounts receivable, firmly committed purchase transactions, and forecasted product sales with foreign exchange forward contracts. In general, these contracts do not expose us to market risk because gains and losses

        76



        on the contracts offset gains and losses on the transactions being hedged. Our exposure to credit risk from these contracts is a function of changes in interest and currency exchange rates and, therefore, varies over time. Gilead limits the risk that counterparties to these contracts may be unable to perform by transacting only with major U.S. banks. We also limit risk of loss by entering into contracts that provide for net settlement at maturity. Therefore, our overall risk of loss in the event of a counterparty default is limited to the amount of any unrecognized and unrealized gains on outstanding contracts (i.e., those contracts that have a positive fair value) at the date of default. We do not enter into speculative foreign currency transactions and do not write options. We presently do not hedge our net investment in any of our foreign subsidiaries. In accounting for hedges of accounts receivable, we record the changes in the fair value in selling, general and administrative expense, as these derivative instruments are not designated as hedges under FAS No.SFAS 133.

        We selectively hedge anticipated currency exposures by purchasing forward contracts to hedge firmly committed purchases transactions and anticipated productsproduct sales over the next year or less, which are designated as cash flow hedges under SFAS 133. The unrealized gains and losses on the underlying forward contracts are recorded in other comprehensive income and recognized in earnings when the forecasted transaction occurs. At December 31, 20022003 and December 31, 2001,2002, we have net unrealized losses on our open foreign exchange forward contracts of $1.1$14.5 million and $0.9$1.1 million, respectively. Losses on revenue hedges reduced product revenuessales by $2.8 million in 2003 and by $1.0 million in 2002.

        We had notional amounts on forward exchange contracts outstanding of $405.0 million at December 31, 2003 and $53.5 million at December 31, 2002 and $72.3 million at December 31, 2001.

        Fair Value of Financial Instruments

        The Company'sCompany’s financial instruments consist principally of cash and cash equivalents, marketable securities, accounts receivable, certain other non-current assets, forward foreign exchange contracts, accounts payable, long-term obligations and convertible notes. Cash and cash equivalents, marketable securities and forward foreign exchange contracts that hedge accounts receivable are reported at their respective fair values on the balance sheet. Forward foreign exchange contracts that hedge firmly committed purchases and sales are recorded at fair value, net of the related deferred gain or loss, resulting in a reported net balance of zero.

The fair value of the convertible subordinated notes at December 31, 2002 was $381.9 million and the fair value at December 31, 2001 was $382.8 million. The carrying value at the end of each period was $250.0 million. Gilead called the convertible subordinated notes for redemption in November 2003 and converted them to Gilead common stock in December 2003. The fair values at December 31, 20022003 and December 31, 20012002 for each of the convertible notes were determined by obtaining quotes from a market maker for the notes.

                In November 2002, The EITF reached a consensus on Issue 00-21, addressing how to account for arrangements that involve the delivery or performance of multiple products, services, and/or rights to use assets. Revenue arrangements with multiple deliverables are divided into separate units of accounting if the deliverables in the arrangement meet the following criteria: (1) the delivered item has value to the customer on a standalone basis; (2) there is objective and reliable evidence of the fair value of undelivered items; and (3) delivery of any undelivered item is probable. Arrangement consideration should be allocated among the separate units of accounting based on their relative fair values, with the amount allocated to the delivered item being limited to the amount that is not contingent on the delivery of additional items or meeting other specified performance conditions. The final consensus will be applicable to agreements entered into in fiscal periods beginning after June 15, 2003 with early adoption permitted. We are reviewing the provisions of this consensus to determine the effect, if any, it may have on the Company's financial position or results of operations.

                In November 2002, the FASB issued Interpretation No. 45 (or FIN 45),Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. FIN 45 elaborates on the existing disclosure requirements for most guarantees, including residual value guarantees issued in conjunction with operating lease agreements. It also clarifies that at the time a company issues a guarantee, the company must recognize an initial liability for the fair value of the obligation it assumes under that guarantee and must disclose that information in its interim and annual financial statements. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002. Our adoption of the disclosure provisions of FIN 4546 did not have a material impact on our results of operations andconsolidated financial position.statements.

                In December 2002, the FASB issued SFAS No. 148,Accounting for Stock-Based Compensation—Transition and Disclosure. SFAS 148 is an amendment to SFAS No. 123,Accounting for Stock-Based Compensation issued in October 1995. SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based compensation. In addition, this Statement amends the disclosure requirements of Statement 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The additional disclosure requirements of FAS 148 are effective for fiscal years ending after December 15, 2002. We have elected to continue to follow the intrinsic value method of accounting as prescribed by Accounting Principles Board Opinion No. 25 (or APB 25),Accounting for Stock Issued to Employees, to account for employee stock options.

        2.    CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING PRINCIPLE

                In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 (SAB 101),Revenue Recognition in Financial Statements. Among other things, SAB 101 describes the SEC Staff's position on the recognition of certain nonrefundable up-front fees received in connection with collaboration agreements. We previously recognized nonrefundable technology access fees received in connection with collaboration agreements as revenue when received or when collectibility was probable, and when the technology had been transferred. Effective January 1, 2000, Gilead changed its method of accounting for these fees to recognize them as the related manufacturing obligation is fulfilled or on a straight-line basis over the term of the related research and development collaboration, manufacturing or supply arrangement, as appropriate, as this method best matches the effort provided. Management believes the change in accounting principle is preferable based on guidance provided in SAB 101.

                The cumulative effect of the change in accounting principle was recorded in the fourth quarter of 2000, retroactively effective as of January 1, 2000, as deferred revenue that will be recognized as contract revenue over the remaining term of the research and development, manufacturing or supply arrangements, as appropriate. For the year ended December 31, 2000, the net impact of the change in accounting principle was to increase the net loss by $10.7 million, or $0.06 per share. The loss consists of a $13.7 million cumulative effect of the change as of January 1, 2000, net of $2.9 million of related deferred revenue that was recognized as contract revenue during the year 2000. An additional $4.7 million of contract revenue was recognized through 2002, and the remainder of the $6.1 million related deferred revenue balance as of December 31, 2002, is expected to be recognized as revenue through 2012.

        3.   DERIVATIVE FINANCIAL INSTRUMENTS

        On January 1, 2001, Gilead adopted SFAS 133. The standard requires that Gilead recognize all derivatives as either assets or liabilities measured at fair value. The Company entersWe enter into foreign currency forward contracts to hedge against changes in the fair value of monetary assets and liabilities denominated in a non-functional currency. If the derivative is designated as, and meets the definition of, a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings.

        The Company also enters into foreign currency forward contracts, generally with maturities of 12 months or less, to hedge future cash flows related to purchase transactions and forecasted product sales in foreign denominated currencies. These derivative instruments are employed to eliminate or minimize certain foreign currency exposures that can be confidently identified and quantified. In accordance with SFAS 133, hedges related to anticipated foreign currency purchases of raw materials and forecasted product sales designated and documented at the inception of the respective hedge are designated as cash flow hedges and evaluated for effectiveness quarterly. As the terms of the forward contract and the underlying transaction are matched at inception, forward contract effectiveness is calculated by comparing the fair value of the contract to the change in the forward value of the underlying hedged item. Upon adoption of SFAS 133, we recorded a fair value of $0.6 million related to forward contracts previously not reflected in the balance sheet and recognized a cumulative transition adjustment to other comprehensive income of $0.6 million for theThe effective component of the hedge.hedge is recorded in accumulated other comprehensive income.

See Note 10. These warrants have net exercise features and under SFAS 133 are classified as derivative instruments. Upon adoption, Gilead recorded the fair value of one of these warrants at $1.1 million with an offsetting adjustment to cumulative change in accounting principle.

        During 2002,2003, a $0.4$5.1 million loss on hedging contracts has been recognized in the consolidated income statement and a $0.2$1.0 million increasedecrease in the fair value of derivatives has been recognized in accumulated other comprehensive income. At December 31, 2002,2003, the fair value of derivatives included in accumulated other comprehensive income is not material.

        3.   ACQUISITION OF TRIANGLE PHARMACEUTICALS, INC.

        On January 23, 2003, we completed the acquisition of all of the net assets of Triangle to expand our antiviral pipeline. Triangle was a development stage company with a particular focus on potential therapies for HIV, including AIDS, and the hepatitis B virus (HBV). Triangle’s portfolio consisted of several drug candidates in clinical trials, including Emtriva (emtricitabine) for the treatment of HIV infection, emtricitabine for the treatment of chronic hepatitis B, amdoxovir for the treatment of HIV infection and clevudine for the treatment of chronic hepatitis B. In July 2003, the U.S. Food and Drug Administration (FDA) approved for marketing Emtriva for the treatment of HIV and in October 2003, the European Commission granted Marketing Authorisation for Emtriva in all fifteen member states of the European Union.

        The Triangle acquisition has been accounted for as an acquisition of assets rather than as a business combination in accordance with the criteria outlined in Emerging Issues Task Force 98-3. Triangle was a development stage company that had not commenced its planned principal operations. It lacked the necessary elements of a business because it did not have completed products and, therefore, no ability to access customers. The results of operations of Triangle since January 23, 2003 have been included in our consolidated financial statements and primarily consist of research and development expenses and to a lesser extent, selling, general and administrative expenses.

        In December 2002, as part of the arrangements contemplated by the proposed acquisition of Triangle by Gilead, a $50.0 million loan was extended to Triangle for working capital and other corporate purposes. Triangle issued to Gilead a 7.50% unsecured convertible promissory note. Upon completion of the acquisition in January 2003, this loan was eliminated in our consolidated financial statements.

        The aggregate purchase price was $525.2 million, including cash paid of $463.1 million for all of the outstanding stock, the fair value of stock options assumed of $41.3 million, estimated direct transaction costs of $14.2 million and employee related costs of $6.6 million.

        As part of the purchase, we established a workforce reduction plan and also assumed obligations under various change of control agreements. As of the acquisition date, approximately $6.2 million of employee termination costs and change of control obligations had been recorded as a liability to be paid

The $4.6 million value assigned to the assembled workforce was being amortized over three years, the estimated useful life of the asset. The deferred compensation represents the intrinsic value of the unvested stock options assumed in the transaction and will be amortized over the remaining vesting period of the options, which extends through January 2007.

        Upon the reversal of the deferred tax asset valuation allowance in the fourth quarter of 2003, the remaining $3.2 million assembled workforce asset was eliminated. See Note 18.

        3.   ACQUISITION OF TRIANGLE PHARMACEUTICALS, INC. (Continued)

        Approximately $488.6 million of the purchase price was allocated to in-process research and development and represented the fair value of Triangle’s incomplete research and development programs that had not yet reached technological feasibility and had no alternative future use as of the acquisition date. A summary of these programs at the acquisition date and updated for subsequent developments follows:

        Program

        Description

        Status of Development

        Emtricitabine for HIV—Single Agent

        A nucleoside analogue that has been shown to be an inhibitor of HIV replication in patients.

        Four phase 3 studies completed. U.S. marketing approval received from the FDA in July 2003 and European Union approval received from the European Commission in October 2003.

        $178.8

        Emtricitabine/ Tenofovir DF Fixed Dose Combination for HIV Therapy

        A potential co-formulation of tenofovir and emtricitabine.

        As of the acquisition date, work had not yet commenced on the potential co-formulation except to the extent that work on emtricitabine as a single agent was progressing. We have since successfully completed co-formulating tenofovir and emtricitabine into a single pill, completed three stability studies and a bioequivalence study required for approval.

        $106.4

        Amdoxovir for HIV

        A purine dioxolane nucleoside that may offer advantages over other marketed nucleosides because of its activity against drug resistant viruses as exhibited in patients with HIV infection.

        Phase 2 trials at acquisition date. Effective January 28, 2004, we announced our intent to terminate the licensing agreement with Emory University and the University of Georgia Research Foundation, Inc. and development will be discontinued.

        $114.8

        Clevudine for HBV

        A pyrimidine nucleoside analogue that has been shown to be an inhibitor of HBV replication in patients chronically infected with HBV.

        Phase 1/2 trials at acquisition date. Effective August 6, 2003, the licensing agreement with Bukwang Pharm. Ind. Co., Ltd was terminated and development was discontinued.

        $58.8

        Emtricitabine for HBV

        An inhibitor of HBV replication in patients chronically infected with HBV.

        Phase 3 trial ongoing.

        3.   ACQUISITION OF TRIANGLE PHARMACEUTICALS, INC. (Continued)

        The remaining efforts for completion of Triangle’s research and development projects primarily consist of clinical trials, the cost, length and success of which are extremely difficult to predict. Numerous risks and uncertainties exist that could prevent completion of development, including the ability to enroll patients in clinical trials, the possibility of unfavorable results of our clinical trials, and the risk of failing to obtain FDA and other regulatory body approvals. Feedback from regulatory authorities or results from clinical trials might require modifications or delays in later stage clinical trials or additional trials to be performed. We cannot be certain that emtricitabine for the treatment of chronic hepatitis B, purchased from Triangle, will be approved in the U.S. or the European Union or whether marketing approvals will have significant limitations on its use. We have terminated our rights with respect to the other potential products that we acquired with the acquisition of Triangle. We also do not yet have approval of the fixed-dose combination product containing tenofovir DF and emtricitabine. Future discussions with regulatory agencies will determine the amount of data needed and timelines for review, which may differ materially from current projections. The acquired products under development may never be successfully commercialized. Emtriva, for example, is a product with many similarities to other existing products. As a result, it may be difficult to successfully penetrate the market and to achieve significant revenues. In addition, emtricitabine for the treatment of chronic hepatitis B faces significant uncertainties associated with pricing, efficacy, and the cost to produce that may not be successfully resolved. As a result, we may make a strategic decision to discontinue development of this product, as we did with clevudine and amdoxovir, if we believe commercialization will be difficult relative to other opportunities in our pipeline. If these programs cannot be completed on a timely basis or at all, then our prospects for future revenue growth would be adversely impacted.

        The value of the acquired in-process research and development was determined by estimating the related future net cash flows between 2003 and 2020 using a present value risk adjusted discount rate of 15.75%. This discount rate is a significant assumption and is based on our estimated weighted average cost of capital adjusted upward for the risks associated with the projects acquired. The projected cash flows from the acquired projects were based on estimates of revenues and operating profits related to the projects considering the stage of development of each potential product acquired, the time and resources needed to complete the development and approval of each product, the life of each potential commercialized product and associated risks including the inherent difficulties and uncertainties in developing a drug compound including obtaining FDA and other regulatory approvals, and risks related to the viability of and potential alternative treatments in any future target markets.

        4.   ACQUISITION OF REAL ESTATE

        In September 2003, we completed the purchase of our Foster City campus for approximately $123.0 million in cash. This purchase included 16 buildings, totaling 496,000 square feet of office and laboratory space on Lakeside Drive in Foster City, California.

        In accordance with SFAS No. 141, Business Combinations and SFAS No. 142, Goodwill and Other Intangible Assets, the purchase price should be allocated between land, buildings and existing in-place leases based on the estimated relative fair values. Land and buildings were recorded at $45.1 million and

        4.   ACQUISITION OF REAL ESTATE (Continued)

        $71.4 million, respectively. The fair value of the buildings will be depreciated over their remaining economic life estimated to be 20 years. We used the market approach to value the existing leases we acquired and recorded an intangible asset of approximately $6.5 million that will be amortized on a straight-line basis to net rental income over approximately two years, the remaining term of the leases. The net rental income we generate from these leases, after amortization of the intangible asset, is included in interest and other income, net and was approximately $0.4 million for the year ended December 31, 2003. Accumulated amortization on the intangible asset was $0.8 million as of December 31, 2003.

        5.   ASSET IMPAIRMENT

        During 2003, we recorded an asset impairment charge of $10.2 million on certain of our long-lived assets, primarily leasehold improvements, manufacturing and laboratory equipment, which we have classified as held for use. This non-cash charge was driven by the decision to terminate our liposomal research and development activities in San Dimas and discontinue the DaunoXome product line. The impairment was based on our analysis of the undiscounted cash flows to be generated from the affected assets as compared to their carrying value. As the carrying value exceeded the related undiscounted cash flows, we wrote the carrying value of the long-lived assets down to fair value in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. Fair value was derived using an expected cash flow approach.

        6.   SALE OF ONCOLOGY ASSETS

        On December 21, 2001, Gilead completed the sale of its oncology assets, pipeline of clinical candidates in oncology and all related intellectual property, as well as our Boulder, Colorado operations, including clinical research and drug development operations, infrastructure and facilities, to OSI. The three clinical development candidates sold to OSI were: NX 211 (liposomal lurtotecan), GS 7836 (a nucleoside analogue) and GS 7904L (a liposomal thymidylate synthase inhibitor). As consideration, Gilead received $130.0 million in cash and 924,984 shares of OSI common stock valued at approximately $38.8 million as of December 21, 2001. The number of shares issued to Gilead was determined by dividing $40.0 million by the average closing sale price of OSI common stock for the 5 days preceding December 21, 2001. We are also entitled to additional payments from OSI of up to $30.0 million in either cash or a combination of cash and OSI common stock if and when OSI reaches certain development milestones for NX 211, the most advanced of the oncology product candidates sold to OSI. Milestone payments, if any, received from OSI will be recognized as contract revenues upon receipt. Based upon the December 21, 2001 net book value of the oncology assets sold of $5.0 million, transaction costs of $3.2 million, and $2.8 million related to the acceleration of approximately 78,000 options to purchase Gilead common stock, we realized a pretax gain of $157.8 million in the fourth quarter of 2001. The carrying value of the transferred assets relates primarily to certain property and equipment. OSI assumed all of Gilead'sGilead’s oncology-related clinical and preclinical obligations, as well as various lease obligations. Under a related manufacturing agreement, we will produce for OSI liposomal formulations of NX 211 and GS 7904L, the two liposomal products sold to OSI, at our manufacturing facility in San Dimas, CA.

        In July 2002, Gilead sold all of its remaining shares of OSI common stock for approximately $22.0 million. These shares were partial consideration for the sale of our oncology assets to OSI in December 2001, at which time they were recorded at a fair market value of approximately $38.0 million. In connection with the sale of these remaining shares, we recognized a non-operating loss of approximately $16.0 million that is reflected in our consolidated results of operations for the year ended December 31, 2002.

        Chiron Corporation

        In August 2003, we entered into a non-exclusive licensing agreement with Chiron Corporation (Chiron) for the research, development and commercialization of small molecule therapeutics against selected hepatitis C virus (HCV) drug targets. Under the agreement, Gilead received non-exclusive rights to use Chiron’s HCV technology to develop and commercialize products for the treatment of HCV. Under the terms of the agreement, we paid Chiron an up-front license fee that was recorded as research and development expense as there is no future alternative use for this technology. We also agreed to make additional payments to Chiron if certain clinical and regulatory milestones are met and royalty payments in the event a product is developed using the licensed technology.

        Japan Tobacco Inc.

        In July 2003, Gilead entered into a licensing agreement with Japan Tobacco Inc. (Japan Tobacco) under which Japan Tobacco will commercialize products in our HIV portfolio in Japan. The agreement includes Viread, Emtriva and a future co-formulation of the two products. Under the terms of the agreement, we received an up-front fee and are entitled to receive additional cash payments upon achievement of certain milestones. Japan Tobacco also will pay us a royalty on net sales, if any, of these products in Japan. The up-front fee has been recorded as deferred revenue and will be amortized into contract revenue over the period of our remaining obligations under the agreement, approximately 14 years.

        Emory University

        In April 1996, Triangle obtained, and in January 2003 we acquired as part of our acquisition of Triangle, an exclusive worldwide license to all of Emory University’s rights to purified forms of emtricitabine for use in the HIV and the hepatitis B fields. We are obligated to make certain milestone and royalty payments to Emory, including annual minimum royalties beginning the third year after the first FDA registration is granted for an anti-HIV product incorporating the emtricitabine technology in the U.S. and the third year after the first registration is granted for an anti-hepatitis B product incorporating the emtricitabine technology in certain major market countries, for the HIV and hepatitis B indications, respectively. In 2002, Triangle began paying license maintenance fees because development milestones had not yet been achieved.

        The license agreement with Emory terminates upon the later of patent expiration or the expiration of our obligation to pay royalties. In addition, we have the right to terminate the agreement in its entirety or with respect to one or both indications (HIV and HBV) in one or more countries prior to expiration at any time upon 90 days notice.

        GlaxoSmithKline

        GlaxoSmithKline

        In April 2002, Gilead and GSK entered into a licensing agreement providing GSK the rights to commercialize Hepsera Gilead's, our antiviral for the treatment of chronic hepatitis B, in Asia, Latin America and certain other territories. Under the agreement, Gileadwe retained rights to Hepsera in the United States,U. S., Canada, Eastern and Western Europe, Australia and New Zealand.

        for the treatment of chronic hepatitis B in all of its territories, the

        82



        most significant of which include China, Korea, Japan and Taiwan. In addition, GSK paid us an up-front licensing fee of $10.0 million as the first payment against these additional obligations and, we are entitled to receive additional cash payments ofmay pay up to $30.0 million upon achievement by GSK of certain regulatory, development and commercial milestones. Of this $30.0 million, $2.0 million was received for the U.S. approval of Hepsera in September 2002.2002 and $2.0 million was received for the Canadian approval of Hepsera in August 2003. GSK also will pay Gileadus a royalty on net sales, if any, of Hepsera in the GSK territories. GSK will have full responsibility for development and commercialization of Hepsera in GSK'sGSK’s territories. The $10.0 million up-front fee and $2.0$4.0 million U.S.of approval feefees have been recorded as deferred revenue in 2002 with a total of $0.9 million and $0.5 million being recognized as contract revenue in 2002.2003 and 2002, respectively. The $12.6 million balance of deferred revenue at December 31, 20022003 will be amortized into contract revenue over the period of Gilead'sour remaining obligations under the agreement, approximately 1412 years.

        In December 2000, Gilead entered into an agreement with Glaxo Wellcome, now GSK, giving Gilead the rights to GS 7904L, a novel anti-tumor compound. Gilead was developing GS 7904L in a liposome and was evaluating it in preclinical studies. Under the agreement, Gilead had exclusive worldwide rights to develop and commercialize GS 7904L for all indications other than malaria. Gilead paid GSK an up-front fee that was included in R&D expense in 2000. In December 2001, this compound was assigned to OSI as part of the sale of oncology assets.

        In May 1998, Gilead entered into a three-part collaboration with GSK in whichwhich: (a) GSK received a non-exclusive right to use Gilead'sGilead’s proprietary SELEX process for target validation; (b) Gilead received exclusive rights (subject to GSK'sGSK’s right to elect to participate in such activities) to develop and commercialize NX 211, a liposomal formulation of GSK'sGSK’s proprietary topoisomerase I inhibitor (lurtotecan); and (c) GSK acquired 1,457,028 shares of Gilead common stock for $10.0 million in a private offering. In December 2000, the collaboration and license agreement was modified. Under the revised terms of agreement, GSK waived its right to participate in the development and commercialization of NX 211 and its right to receive royalties, giving Gilead exclusive rights to the compound. In December 2001, this compound was also assigned to OSI as part of the sale of oncology assets.

        Cubist Pharmaceuticals

        In September 2002, Gilead and Cubist Pharmaceuticals jointly announced the termination of their licensing agreement for the commercialization of Cidecin®Cidecin® (daptomycin for injection) and an oral formulation of daptomycin. The agreement, executed in January 2001, granted Gilead exclusive commercialization rights to the products in 16 European countries following regulatory approval. Under the terms of the termination agreement, Gilead does not owe any future payments to Cubist, and Cubist reacquired all European rights to both products. Upon termination, $2.0 million was recorded to research and development expense, which represented the remaining unamortized asset related to the preclinical oral formulation of daptomycin.

        Archemix

        In October 2001, we entered into an agreement with Archemix Corporation relating to our SELEX technology. Under this agreement, Archemix obtained the exclusive rights to the SELEX process, including therapeutic and other commercial applications to the extent not already licensed under pre-existing agreements. Archemix paid to us $9.0 million in 2001 and $8.5 million in 2002. As

        83



        required by our license agreement with University License Equity Holdings, Inc. (ULEHI), we paid 5% of the $9.0these receipts to ULEHI, therefore we recognized $8.1 million and the $8.5 million payments to ULEHI and we recognized $8.6 million and $8.1 million as revenue in 2002 and 2001, respectively. We also received a warrant to purchase 350,000 shares of Archemix common stock, the value of which is not material. As required by our license agreement with ULEHI, we transferred 5% of this warrant at that time. We have since transferred the remainder of the warrant to ULEHI. No additional payments are due by Archemix under this agreement.

        EyeTech

        In March 2000, Gileadwe entered into an agreement with EyeTech Pharmaceuticals, Inc. relating to our proprietary aptamer EYE001, now known as Macugen. Currently in earlyPhase 3 clinical trials, Macugen is an inhibitor of vascular endothelial growth factor, or VEGF, which is known to play a role in the development of certain ophthalmic diseases. Under the terms of the agreement, EyeTech received worldwide rights to all therapeutic uses of Macugen, and, if the product is successfully commercialized, EyeTech will pay us royalties on worldwide sales of the product. EyeTech also will be responsible for all research and development costs. We provided clinical supplies of the product to EyeTech through March 2001. We also received a $7.0 million up-front licensing fee from EyeTech in April 2000, which was recognized as revenue ratably over the one-year supply agreement period. Accordingly, $5.2 million of the license fee was recorded as contract revenue under the agreement in 2000, and the remainder of the license fee was recognized as revenue in 2001. We are also entitled to additional cash payments from EyeTech of up to $25.0 million if and when EyeTech reaches certain Macugen development milestones. Additionally, we received a warrant to purchase 791,667 shares of EyeTech series B convertible preferred stock, exercisable at a price of $6.00 per share, the price at which the stock was issued to other investors. See Note 32 for a description of the accounting treatment of the warrant.

        Fujisawa

        Our rights to market AmBisome are subject to a 1991 agreement between Gilead and Fujisawa Healthcare, Inc., as successor to Fujisawa USA, Inc. (Fujisawa). Under the terms of the Fujisawa agreement, as amended, Fujisawa and Gilead co-promote AmBisome in the U.S., Fujisawa has sole marketing rights to AmBisome in Canada and we have exclusive marketing rights to AmBisome in the rest of the world, provided we pay royalties to Fujisawa in connection with sales in most significant Asian markets, including Japan. In connection with U.S. sales, Fujisawa purchases AmBisome from Gilead at cost. For sales in Canada, Fujisawa purchases AmBisome at cost plus a specified percentage. Fujisawa collects all payments from the sale of AmBisome in the U.S. and Canada. We receive 20% of Fujisawa'sFujisawa’s gross profits from the sale of AmBisome in the U.S. Gross profits include a deduction for cost of goods sold, giving us a current effective royalty rate of approximately 17% of Fujisawa'sFujisawa’s net sales of AmBisome in

        the U.S. In connection with the agreement between us and Fujisawa, we recorded royalty revenue of $12.5 million in 2003, $15.7 million in 2002 and $17.1 million in 2001 and $13.5 million in 2000.2001.

        Sumitomo

        In September 1996, Gilead and Sumitomo entered into an agreement pursuant to which Sumitomo agreed to develop and market AmBisome in Japan. Under the terms of the agreement, Sumitomo paid us an initial $7.0 million licensing fee (less withholding taxes of $0.7 million) in October 1996 and a $3.0 million milestone payment (less withholding taxes of $0.3 million) in March 1998. Sumitomo also is required to make additional payments to us if certain clinical and commercial milestones are met and to pay us royalties on all Japanese AmBisome sales. Under the agreement, Gilead is obligated to provide a certain quantity of AmBisome to Sumitomo at no charge. AmBisome is not yet approved for marketing in Japan.

                Subsequent to the cumulative effect of the change in accounting principle that was recorded effective in the first quarter of 2000 resulting from the adoption of SAB 101, Gilead has recognized the initial license fee over the remaining free supply arrangement period. The net impact of the change in accounting principle for the Sumitomo License was to increase the net loss in 2000 by $3.4 million. The cumulative effect of the change in accounting principle was a charge of $5.0 million. Contract revenue of $1.6 million related to the initial licensing fee from Sumitomo was recognized as contract revenue in 2000, $2.8 million was recognized as contract revenue in 2001 and the remaining $0.6 million was recognized as contract revenue in 2002.

        Roche

        In September 1996, Gilead entered into a collaboration agreement with Roche to develop and commercialize therapies to treat and prevent viral influenza (the Roche Agreement). Under the Roche Agreement, Roche received exclusive worldwide rights to Gilead'sGilead’s proprietary influenza neuraminidase inhibitors. Prior to 2000, Roche made license fee and developmental milestone payments totaling $29.1 million. During 2000, Gilead recognized $9.6 million of contract revenue from milestone payments from Roche related to Tamiflu milestones achieved during the year. The milestones included filing for regulatory approval in Japan for treatment of influenza, the Japanese approval of the application, the filing for U.S. regulatory approval for the prevention of influenza, and the receipt of such approval in the U.S. In 2001, we recognized a $2.0 million milestone payment for the filing of an application to market Tamiflu as a prophylaxis in the European Union. In 2002, we recognized $8.0 million in milestone payments for the European approval of Tamiflu for treatment and prophylaxis.

        As of December 31, 2002,2003, Gilead is entitled to additional cash payments from Roche of up to $1.6 million upon Roche achieving additional developmental and regulatory milestones. In addition, Roche is required to pay Gilead royalties on net product sales. Gilead began receiving royalties from Roche'sRoche’s sales of Tamiflu in the first quarter of 2000. We recorded a total of $3.4$12.0 million of Tamiflu royalties in 2003, $3.4 million of royalties in 2002 and $4.5 million of royalties in 2001 and $9.6 million of royalties in 2000.2001. We recognize royalty revenue from Roche in the quarter following the quarter in which the related Tamiflu sales occur.

                Under the Roche Agreement, Roche also reimburses us for its related R&D costs under the program by funding such costs quarterly and generally in advance, based on an annual budget. Reimbursements are included in contract revenue as we incur the related R&D costs. AmountsPfizer

        incurred by us in excess of amounts funded may also be reimbursed, subject to Roche's approval. In this event, revenue is not recognized until such approval has been obtained. Conversely, if amounts funded by Roche exceed our related R&D costs, we may be required to repay such excess funding to Roche. We recorded contract revenue for R&D reimbursements related to the Roche Agreement of approximately $1.1 million over the previous three years ending in 2002. R&D costs related to the Roche Agreement approximate the reimbursement revenue and are included in R&D expenses.

        Pharmacia

        In August 1996, Gilead and Pfizer (formerly Pharmacia Corporation (Pharmacia)Corporation) entered into a License and Supply Agreement (Pharmacia(Pfizer Agreement) to market Vistide in all countries outside the U.S. Under the terms of the PharmaciaPfizer Agreement, PharmaciaPfizer paid Gilead an initial license fee of $10.0 million.

        Subsequent to the cumulative effect of the change in accounting principle recorded effective in the first quarter of 2000, Gilead is recognizing the initial license fee on a straight-line basis over the supply arrangement period, which is sixteen years from the agreement date. The net impact of the change in accounting principle for the PharmaciaPfizer Agreement was to increase the net loss in 2000 by $7.3 million. The

        10.   COLLABORATIVE ARRANGEMENTS AND CONTRACTS (Continued)

        cumulative effect of the change in accounting principle related to the initial license fee from PharmaciaPfizer was a $7.9 million charge to results of operations, and additional contract revenue of $0.6 million was recognized in 2000 subsequent to the accounting change. The remaining $7.3 million of related deferred revenue is expected to be recognized on a straight-line basis as contract revenue over the remaining supply period, through 2013.

        Under the terms of the PharmaciaPfizer Agreement and related agreements covering expanded access programs for Vistide outside of the U.S., Gilead is responsible for maintaining the cidofovir patent portfolio and for supplying to PharmaciaPfizer bulk cidofovir used to manufacture the finished Vistide product. Gilead is entitled to receive a royalty based upon Pharmacia'sPfizer’s sales of Vistide. Gilead receives a portion of the royalty upon shipping either bulk drug substance or Vistide to Pharmacia,Pfizer, and the remainder upon Pharmacia'sPfizer’s sale of Vistide to third parties. Any royalties that Gilead receives before the product is sold to third parties are recorded as deferred revenue until such third-party sales occur. At December 31, 2002,2003, we have recorded on our balance sheet approximately $1.9$2.6 million of such deferred revenue ($3.11.9 million at December 31, 2001)2002). We recognized royalty revenue from sales of Vistide outside of the United States by Pharmacia of $1.3 million in 2003, $1.3 million in 2002 and $1.4 million in 2001 and $1.5 million in 2000.2001.

        Somalogic

                In November 1999, Gilead and Somalogic, Inc. (Somalogic) entered into an agreement whereby Gilead assigned to Somalogic under a sole and exclusive license, certain intellectual property related to the SELEX process for diagnostic purposes, including patents and patent applications. Under the terms of the agreement, Somalogic was required to pay Gilead a total of $2.5 million in two nonrefundable installments. The first $1.5 million was paid in November 1999 and was included in contract revenue for the year ended December 31, 1999. The remaining $1.0 million, which was reported as deferred revenue at December 31, 1999, was received and recorded as contract revenue in 2000. Gilead has no ongoing research or funding obligations under the agreement.

        86



        IOCB/REGA

        In 1991 and 1992, Gilead entered into agreements with the Institute of Organic Chemistry and Biochemistry of the Academy of Sciences of the Czech Republic and Rega Stichting (IOCB/REGA) relating to certain nucleotide compounds discovered at these two institutions. Under the agreements, Gilead received the exclusive right to manufacture, use and sell these nucleotide compounds, and Gilead is obligated to pay IOCB/REGA a percentage of net revenues received from sales of products containing the compounds, subject to minimum royalty payments. The products covered by the agreement include Vistide, Hepsera and Viread, but exclude Tamiflu. Gilead currently makes quarterly payments to IOCB/REGA based on a percentage of Vistide, Hepsera and Viread sales.

        In December 2000, the agreements with IOCB/REGA were amended to provide for a reduced royalty rate on future sales of Hepsera or Viread, in return for an up-front payment from Gilead of $11.0 million upon signing the agreement. This payment was recorded as a long-term prepaid royalty and is classified in other noncurrent assets on the balance sheet at December 31, 20022003 and 2001.2002. It is being recognized as royalty expense over the expected commercial life of Viread and Hepsera. Amortization of the $11.0 million payment began as of the product launch dates of Viread and Hepsera and totaled $0.5$1.7 million through December 31, 2002.2003.

        Southern Research Institute

        In December 2000, Gilead entered into an agreement with Southern Research Institute giving Gilead worldwide rights to develop and commercialize GS 7836, an anti-tumor compound that Gilead was evaluating in preclinical studies. Under the terms of the agreement, Gilead paid Southern Research Institute an up-front fee, which was included in research and development expense in 2000. In December 2001, this compound was assigned to OSI as part of the sale of oncology assets.

        11.   INVESTMENT IN AND SALE OF UNCONSOLIDATED AFFILIATE

        In July 1998, we established Proligo L.L.C., a Delaware limited liability company (Proligo), as a wholly owned subsidiary and transferred all of the assets of the NeXstar Technology Products division to Proligo. Proligo supplies nucleic acid and peptide synthesis products to the pharmaceutical and biopharmaceutical industry for sale and use as laboratory research reagents and in therapeutic and diagnostic products.

        In August 1998, we sold a 51% interest (Interest) in Proligo to SKW Americas, Inc. (SKW).a third party. As payment for the Interest, we received $15.0 million in cash and a 49% interest in PerSeptive Biosystems GmbH, a company in Hamburg, Germany, (Hamburg Company), which specializes in the manufacture of nucleoside phosphoramidite monomers. The 49% interest in the Hamburg Company had a fair market value of approximately $5.5 million. We recorded a $22.1 million gain in connection with this sale in 1998.

                In JanuaryPrior to February 2000, and October 1999, Gileadwe made two additional cash investments in Proligo for a total of $5.0 million to maintain itsour 49% ownership interest in Proligo. Gilead had no commitments to provide additional funding to Proligo beyond January 2000.

        87



        We accounted for our investment in Proligo using the equity method of accounting. In 2000, we recognized $2.9 million equity in Proligo's net loss, representing our 49% share of Proligo's loss for the thirteen-month period ended December 31, 2000. During the fourth quarter of 2000, Proligo changed its fiscal year end to December 31 from November 30. During 2001, Gilead sold its 49% interest in Proligo to Degussa Corporation for $14.3 million in cash. The proceeds, net of Gilead'sGilead’s investment in Proligo, are reflected as an $8.8 million gain on the sale of unconsolidated affiliate. In 2001, prior to the date of the sale, Gilead recorded $2.1 million as equity in the loss of Proligo.

        Contingent Liability

                Gilead has subleased certain of its facilities, primarily in California, through 2003. If any of the sublessees default on their obligations under these subleases, we would be primarily liable to the original lessor. The total future amounts due under these leases as of December 31, 2002 is $3.9 million.

        Legal Proceedings

        In 1997 we reached a settlement with Elan Corporation, plc (Elan, the successor company to The Liposome Company) in which both companies agreed to dismiss all legal proceedings involving AmBisome, Gilead'sGilead’s liposomal formulation of amphotericin B. Under the terms of the initial settlement agreement in 1997, we made an initial payment to Elan of $1.8 million and agreed to make additional royalty payments through 2006, based on AmBisome sales. In 1997, we recorded a $10.0 million accounting charge for the accrued litigation settlement expenses, representing the estimated net present value of all future minimum payments we were required to make. In June 2002, Elan and Gilead entered into an agreement terminating our remaining AmBisome payment obligations under the initial settlement agreement in exchange for a payment to Elan of $7.3 million. The excess of the $7.3 million settlement amount over the remaining accrued litigation settlement expenses balance of $6.0 million is being amortized over the remaining life of the patents, approximately four years.

In addition, Westchester argues that the defendants, including Gilead, did not accurately report the “best price” under the Medicaid Program.

        itself against the allegations. The complaint seeks an undetermined amount of damages, as well as other relief, including declaratory and injunctive relief.

        Other defendants in this lawsuit have been named in numerous other lawsuits with comparable AWP allegations. To our knowledge, Gilead has not been named in these other lawsuits. Were Gilead to be named and served in other lawsuits with comparable AWP allegations, adverse results could result in material damages.

        A purported class action complaint was filed on November 10, 2003 in the United States District Court for the Northern District of California against Gilead and our Company’s Chief Executive Officer, Chief Financial Officer, Executive Vice Presidents of Operations and Research and Development, and Senior Vice Presidents of Manufacturing and Research. The complaint alleges that the defendants violated the federal securities laws, specifically Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 of the Securities and Exchange Commission, by amongstmaking certain alleged false and misleading statements. The plaintiff seeks unspecified damages on behalf of a purported class of purchasers of the Gilead’s securities during the period from July 14, 2003 through October 28, 2003. Other similar actions were subsequently filed and the court issued an order consolidating the lawsuits into a single action on December 22, 2003. We believe that we have meritorious defenses to the allegations contained in the complaint and intend to defend the case vigorously. No trial date has been scheduled. On February 9, 2004, the court issued an order appointing lead plaintiffs in the action, and these lead plaintiffs have until March 25, 2004 to file a consolidated complaint.

        In December 2003, two purported shareholder derivative lawsuits were filed by individual shareholders on behalf of Gilead against its directors and certain executive officers in the Superior Court of the State of California, County of San Mateo alleging, among other things, assigning rights underthat defendants violated the agreement without ULEHI's consent.California Corporations Code and breached fiduciary duties owing to Gilead. Gilead is named as a nominal defendant. The plaintiffs seek unspecified damages on behalf of Gilead in connection with alleged insider trading during the period between July 14, 2003 and October 28, 2003 and defendants’ alleged breach of their fiduciary duties, abuse of control, waste and mismanagement. The two cases were consolidated into a single action on January 15, 2004 and plaintiffs filed a consolidated complaint on February 12, 2004. No trial date has been scheduled. We contest ULEHI's allegations. We have metintend to take all appropriate action to defend our interests in connection with ULEHI regarding these allegations and are actively engaged in negotiations to settle this disagreement. If these negotiations prove unsuccessful and ULEHI chooses to terminate the ULEHI-Gilead agreement, an arbitration concerning this termination would likely result. An unfavorable outcome in such an arbitration could give rise to an award against us of monetary damages or other adverse remedies, possibly including conveyance to ULEHI of Gilead's rights and obligations under the ULEHI licensing agreement and our sublicenses.litigation.

        We are also a party to various other legal actions that arose in the ordinary course of our business. We do not believe that any of these other legal actions will have a material adverse impact on our business, results of operations or financial position.

        Employee Stock Purchase Plan

        Under Gilead'sGilead’s Employee Stock Purchase Plan (ESPP), employees can purchase shares of Gilead common stock based on a percentage of their compensation. The purchase price per share must equal at least the lower of 85 percent of the market value on the date offered or the date purchased. A total of 6,320,0006.3 million shares of common stock have been reserved for issuance under the ESPP. As of December 31, 2002, 4,643,0222003, 4.9 million shares of the total shares reserved had been issued under the ESPP (4,300,708(4.6 million shares as of December 31, 2001)2002).

        Stock Option Plans

        In December 1987, Gilead adopted the 1987 Incentive Stock Option Plan and the Supplemental Stock Option Plan for issuance of common stock to employees, consultants and scientific advisors. In April 1991, the Board approved the granting of certain additional nonqualified stock options with terms and conditions substantially similar to those granted under the 1987 Supplemental Stock Option Plan. None of the options issued under the plans described above had exercise prices that were less than the fair value of the underlying stock on the date of grant. The options vest over five years pursuant to a formula determined by the Board and expire after ten years. No shares are available for grant of future options under any of these plans.

        In November 1991, Gilead adopted the 1991 Stock Option Plan (1991 Plan) for issuance of common stock to employees and consultants. Options issued under the 1991 Plan shall, at the discretion of the Board, be either incentive stock options or nonqualified stock options. In May 1998,

        91



        the 1991 Plan was amended such that the exercise price of all stock options must be at least equal to the fair value of Gilead'sGilead’s common stock on the date of grant. The options vest over five years pursuant to a formula determined by the Board and expire after ten years. The 1991 Plan was amended and restated in April 2000 to extend the term of the plan through 2010. In May 2002 the stockholders approved an amendment to the 1991 Plan that increased the total number of authorized shares under the plan from 47,000,000 to 53,000,000. At December 31, 2002,2003, there were 14,459,4459,570,258 shares available for grant of future options under the 1991 Plan.

        In November 1995, Gilead adopted the 1995 Non-Employee Directors'Directors’ Stock Option Plan (Directors'(Directors’ Plan) for issuance of common stock to non-employee Directors pursuant to a predetermined formula. The exercise price of options granted under the Directors'Directors’ Plan must be at least equal to the fair value of Gilead'sGilead’s common stock on the date of grant. TheFor options vestgranted before January 2003, vesting is over five years from the date of grant in quarterly five percent installments andinstallments. Initial options granted after January 2003 to new Directors vest over three years from the date of grant in equal annual installments. Annual grants thereafter to existing Directors vest after 12 months. All options expire after ten years. In May 2002, the stockholders approved an amendment to the Directors'Directors’ Plan that increased the total number of authorized shares under the Plan from 2,200,000 to 2,800,000. At December 31, 2002,2003, there were 922,200781,200 shares available for grant of future options under the Directors'Directors’ Plan.

        Stock plans assumed by Gilead in the merger with NeXstar include the 1988 Stock Option Plan (1988 Plan), the 1993 Incentive Stock Plan, and the 1995 Director Option Plan (collectively, NeXstar Plans).

        converted into options to purchase Gilead common stock as a result of the merger and remain subject to their original terms and conditions. No shares are available for grant of future options under any of the NeXstar Plans.

                NeXstar'sNeXstar’s 1988 Plan allows certain option holders to execute cashless exercises of options. In a cashless exercise transaction, the option holder specifies how many shares will be exercised and Gilead issues the specified number of shares, less the number that would be required to cover the exercise price based on the fair value of the stock on the exercise date. During 2002 2001 and 2000,2001, several option holders performed cashless exercises. As a result, such option awards are considered to be variable and, therefore, we recognized a nominal amount of compensation expense in 2002 and $0.6 million in 2001 and $0.5 million in 2000.2001. As of July 2002, there were no more options outstanding in this category.

        Stock plans assumed by Gilead in the acquisition of the net assets of Triangle include the 1996 Stock Option Plan and a separate plan for the chief executive officer of Triangle (collectively, Triangle Plans). Options pursuant to each plan that were issued and outstanding as of January 23, 2003 have been converted into options to purchase approximately 2.0 million shares of Gilead common stock as a result of the acquisition and remain subject to their original terms and conditions. No shares are available for grant of future options under either of the Triangle Plans.

        The following table summarizes activity under all Gilead, NeXstar and NeXstarTriangle stock option plans for each of the three years in the period ended December 31, 2002.2003.

        The Company has reserved an aggregate of 17,058,62311.7 million shares of common stock for future issuance under equity compensation plans as of December 31, 2002.

        Pro Forma Disclosures

                We have elected to follow Accounting Principles Board Opinion No. 25 (APB 25) to account for employee stock options. Under APB 25, no compensation expense is recognized because the exercise price of our employee stock options equals the market price of the underlying stock on the date of grant.

                The information regarding net income (loss) and earnings (loss) per share prepared in accordance with FAS 123 has been determined as if we had accounted for our employee stock options and

The resulting effect on net income (loss)1991 and earnings (loss) per share pursuant to FAS 123 is not likely to be representative of the effects on net income (loss) and earnings (loss) per share pursuant to FAS 123 in future years, due to subsequent years including additional grants and years of vesting.

        Preferred Share Purchase Rights Plan

        In November 1994, we adopted a Preferred Share Purchase Rights Plan.Plan (Rights Plan). The plan provides for the distribution of a preferred stock purchase right as a dividend for each share of Gilead common stock. The purchase rights are not currently exercisable. Under certain conditions involving an acquisition or proposed acquisition by any person or group of 15% or more of our common stock, the purchase rights permit the holders (other than the 15% holder) to purchase Gilead common stock at a 50% discount from the market price at that time, upon payment of a specified exercise price per purchase right. In addition, in the event of certain business combinations, the purchase rights permit the purchase of the common stock of an acquirer at a 50% discount from the market price at that time. Under certain conditions, the purchase rights may be redeemed by the Board in whole, but not in part, at a price of $.0025 per purchase right. The purchase rights have no voting privileges and are attached to and automatically trade with Gilead common stock.

        In October 1999 and again in October 2003, the Board of Directors approved an amendmentamendments to the purchase rights plan.Rights Plan. The first amendment provided, among other things, for an increase in the exercise price of a right under the plan from $15 to $100 and an extension of the term of the plan from November 21, 2004 to October 20, 2009. The second amendment provides, among other things, for an increase in the exercise price of a right under the plan from $100 (after adjusting for two 2-for-1 stock splits) to $400 and an extension of the term of the Rights Plan to October 27, 2013.

        Acceleration of Stock Options

        In December 2001, we completed the sale of our oncology assets to OSI. As part of this transaction, we accelerated approximately 78,000 options to purchase Gilead common stock with a value of $2.8 million. See Note 46 for further discussion.

        18.   INCOME TAXES (Continued)

        The tax benefits associated with stock option exercises and the employee stock purchase plan resulted in a cumulative tax benefit of $134.2 million during the year ended December 31, 2003. Such benefit was credited to additional paid-in capital when realized.

        Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

        The valuation allowance decreased by $167.6 million for the year ended December 31, 2003 and increased by $14.1 million for the year ended December 31, 2002.

        In December 2003, based upon the level of historical taxable income and projections for future taxable income over the periods that our deferred tax assets are deductible, we determined that it was more likely than not that certain of our deferred tax assets will be realized and therefore released the related valuation allowance. The reversal of the valuation allowance resulted in a realization of income tax benefits of approximately $111.6 million. The deferred tax asset attributable to the net operating loss carryforwards included tax benefits of $129.5 million related to the exercise of employee stock options, which benefits were recorded directly to additional paid in capital. The reversal of the valuation allowance also resulted in the reduction of the remaining assembled workforce asset of $3.2 million established upon the acquisition of Triangle. At December 31, 2002,2003, we have a remaining valuation allowance of $59.2 million against the net deferred tax asset as we have concluded, based on the standard set forth in SFAS No. 109, Accounting for Income Taxes, that it is more likely than not that we will not realize any benefits from the related deferred tax assets. We will assess the need for the valuation allowance at each quarter end based on all available evidence. Approximately $11.0 million of the valuation allowance at December 31, 2003 relates to tax benefits of stock option deductions, which will be credited to additional paid-in capital when realized.

        At December 31, 2003, we had U.S. federal net operating loss carryforwards of $359.3approximately $444.1 million and state net operating loss carryforwards of $11.3approximately $23.6 million. The federal net operating loss carryforwards will expire at various dates beginning in 20112018 through 2020,2022, if not utilized. The state net operating loss carryforwards will expire at various dates from 2004 through 2011, if not

        utilized. In addition, we had federal and state tax credit carryforwards of approximately $31.9$56.0 million and $18.1$11.3 million respectively, which expire in the years 20032004 through 2022.

        Utilization of net operating losses and credits may be subject to an annual limitation due to ownership change limitations provided in the Internal Revenue Code and similar state provisions. This annual limitation may result in the expiration of the net operating losses and credits before utilization.

                The significant increase in income tax expense in 2001 resulted principally from the gain on the sale of our oncology assets to OSI, for which we recorded approximately $3.3 million of federal and state alternative minimum taxes. The provision for 2002 was reduced by a change in U.S. income tax law. This law allows net operating loss carryforward deductions to offset 100% of alternative minimum taxable income, resulting in a reduction of U.S. income tax recorded in the previous years of $1.3 million.

Approximately $71.4 million of the valuation allowance at December 31, 2002 relates to the tax benefits of stock option deductions, which will be credited to additional paid-in capital when realized.

        18.19.   RETIREMENT SAVINGS PLAN

        As of December 31, 2002,2003, Gilead maintains one retirement savings plan under which eligible employees may defer compensation for income tax purposes under Section 401(k) of the Internal Revenue Code. Prior to January 1, 2001, Gilead maintained two separate retirement savings plans. One plan primarily covered former NeXstar employees (NeXstar Plan), and the other plan primarily covered Gilead'sGilead’s remaining eligible employees (Gilead Plan). Under the NeXstar Plan, employee contributions could not exceed 15% of eligible annual compensation. In addition, the NeXstar Plan included a Company match of 50% of employee contributions up to a maximum of 6% of contributions up to an annual maximum Company match of $2,500. At December 31, 2000, approximately $0.6 million, representing 13,857 shares of Gilead common stock, was held by the NeXstar Plan in trust for plan participants. Effective January 2001, the NeXstar Plan was terminated and combined with the Gilead Plan. The shares of Gilead common stock held by the NeXstar Plan were subsequently liquidated and the proceeds were deposited into the various other investment options available under the Gilead plan. Under the Gilead Plan, employees may contribute up to 15% of their eligible annual compensation. Effective January 1, 2000, Gilead began making matching contributions under the Gilead Plan. We contribute up to 50% of an employee'semployee’s first 6% of contributions up to an annual maximum match of $2,500. .Our total matching contribution for the Gilead Plan was $1.4 million in 2003, $1.2 million in 2002 and $1.2 million in 2001 and a combined $0.9 million in 2000 for both plans.2001.

        19.    RELATED PARTY TRANSACTIONS

                Through December 31, 2000, the Chairman of Gilead's Board of Directors was a senior advisor to an investment fund that owns a controlling interest in PharmaResearch Corporation, a contract

        99



        research organization that performs services in connection with clinical studies. Gilead's payments to PharmaResearch Corporation were $10.2 million in 2000.

                In December 2002, as part of the arrangements contemplated by the proposed acquisition of Triangle Pharmaceuticals, Inc. by Gilead, a $50.0 million loan was extended to Triangle for working capital and other corporate purposes. Triangle issued to Gilead a 7.50% unsecured convertible promissory note. Upon completion of the Triangle acquisition in January 2003, this loan was eliminated in our consolidated results as a result of the closing of the acquisition on January 23, 2003. See Note 20.

        20.    SUBSEQUENT EVENTS

                On January 23, 2003, we completed the acquisition of all of the outstanding stock of Triangle, a development stage company. Triangle was active in the development of antiviral drug candidates.

                The aggregate preliminary purchase price was $525.0 million, including the cash paid for the outstanding stock, the fair value of options assumed, estimated direct transaction costs and employee termination costs. We intend to account for this transaction in the first quarter of 2003, and we expect to record a substantial portion of the aggregate purchase price as in-process research and development expense.
