These statements are not guarantees of future performance, rely on a number of assumptions concerning future events, many of which are outside of our control, and involve known and unknown risks and uncertainties that could cause our actual results, performance or achievements, or industry results, to differ materially from any future results, performance or achievements, expressed or implied by such forward-looking statements. We discuss such risks, uncertainties and other factors throughout this report and specifically under the caption “Risk Factors” in Part I, Item 1A. below. Any such forward-looking statements, whether made in this report or elsewhere, should be considered in the context of the various disclosures made by us about our businesses including, without limitation, the risk factors discussed below.

PART I
Item 1. Business
General Development of Our Business
      Allergan, Inc. is a technology-driven, global health care company that develops and commercializes specialty pharmaceutical products for the ophthalmic, neurological, medical aesthetics, medical dermatological and other specialty markets. We are a pioneer in specialty pharmaceutical research, targeting products and technologies related to specific disease areas such as glaucoma, retinal disease, dry eye, psoriasis, acne and movement disorders. Additionally, we develop and market aesthetic-related pharmaceuticals and over-the-counter products. Within these areas, we are an innovative leader in therapeutic and other prescription products, and to a limited degree, over-the-counter products that are sold in more than 100 countries around the world. We are also focusing research and development efforts on new therapeutic areas, including gastroenterology, neuropathic pain and genitourinary diseases.
      We were originally incorporated in California in 1948 and became known as Allergan Corporation in 1950. In 1977, we reincorporated in Delaware. In 1980, we were acquired by SmithKline Beecham plc (then known as SmithKline Corporation). From 1980 through 1989, we operated as a wholly-owned subsidiary of SmithKline and in 1989 we again became a stand-alone public company through a spin-off distribution by SmithKline.
      Our Internet website address is www.allergan.com. We make our periodic and current reports, together with amendments to these reports, available on our Internet website, free of charge, as soon as reasonably practicable after such material is electronically filed with, or furnished to, the Securities and Exchange Commission. The information on our Internet website is not incorporated by reference into this Annual Report on Form 10-K.
      In June 2002, we completed the spin-off of our optical medical device business to our stockholders. The optical medical device business consisted of two businesses: our ophthalmic surgical products business and our contact lens care products business. The spin-off was effected by contributing our optical medical device business to a newly formed subsidiary, Advanced Medical Optics, Inc., or AMO, and issuing a dividend of AMO’s common stock to our stockholders.

      In connection with our spin-off of AMO, we entered into a manufacturing and supply agreement under which we agreed to manufacture certain products for AMO for a period of up to three years ending in June 2005. In October 2004, our board of directors approved certain restructuring activities related to the scheduled termination of our manufacturing and supply agreement. As part of the termination of the manufacturing and supply agreement, we eliminated certain manufacturing positions at our Westport, Ireland; Waco, Texas; and Guarulhos, Brazil manufacturing facilities. As of December 31, 2005, we substantially completed all activities related to the termination of our manufacturing and supply agreement with AMO.
      In January 2005, our board of directors approved the initiation and implementation of a restructuring of certain activities related to our European operations. The restructuring seeks to optimize operations, improve resource allocation and create a scalable, lower cost and more efficient operating model for our European research and development and commercial activities. Specifically, the restructuring anticipates moving key European research and development and select commercial functions from our Mougins, France and other European locations to our Irvine, California, High Wycombe, U.K. and Dublin, Ireland facilities and streamlining our European commercial back office functions. We have incurred and anticipate that we will continue to incur restructuring charges and charges relating to severance, relocation and one-time termination benefits, payments to public employment and training programs, transition and duplicate operating expenses, contract termination costs and capital and other asset-related expenses in connection with the restructuring. We currently estimate that the pre-tax charges resulting from the restructuring, including transition and duplicative operating expenses, will be between $46 million and $51 million, and capital expenditures will be between $3 million and $4 million.
      On December 20, 2005 we entered into a merger agreement with Inamed Corporation and our wholly owned subsidiary, Banner Acquisition, Inc., pursuant to which we intend to acquire Inamed. Inamed is a global healthcare company that develops, manufactures and markets a diverse line of products to enhance the quality of people’s lives, including breast implants for aesthetic augmentation and reconstructive surgery following a mastectomy, a range of dermal products to correct facial wrinkles, the BioEnterics® LAP-BAND® System designed to treat severe and morbid obesity and the BioEnterics® Intragastric Balloon (BIB®) system for the treatment of obesity.
      Consistent with the terms of the merger agreement, we have made an exchange offer for all of the outstanding shares of Inamed common stock on the terms and conditions set forth in the merger agreement and to acquire any shares of Inamed common stock not acquired in the exchange offer in a second step merger. In the exchange offer, Banner Acquisition has offered to acquire Inamed shares for either $84.00 in cash or 0.8498 of a share of our common stock, at the election of the holder, subject to proration so that 45% of the aggregate Inamed shares tendered will be exchanged for cash and 55% of the aggregate Inamed shares tendered will be exchanged for shares of our common stock. Upon completion of the exchange offer, Banner Acquisition will be merged with and into Inamed in the second step merger, with Inamed surviving the merger as our wholly-owned subsidiary. The merger is intended to qualify as a reorganization under Section 368(a) of the Internal Revenue Code. The merger agreement terminates if the exchange offer is not completed by March 30, 2006.
      Inamed had previously executed a merger agreement under which it would be acquired by Medicis Pharmaceutical Corporation. Following its receipt of our acquisition proposal and prior to executing the merger agreement with us, Inamed terminated its merger agreement with Medicis and, in accordance with the terms of that merger agreement, paid Medicis a $90 million cash termination fee.
      The exchange offer is currently scheduled to be completed on March 10, 2006. However, the exchange offer will be extended if necessary to obtain United States Federal Trade Commission, or FTC, clearance. Obtaining clearance from the FTC is the one remaining material condition to closing the exchange offer.

Eye Care Pharmaceutical Product Line
      We develop, manufacture and market a broad range of prescription and non-prescription products designed to treat diseases and disorders of the eye, including glaucoma, dry eye, inflammation, infection and allergy.
      Glaucoma. The largest segment of the market for ophthalmic prescription drugs is for the treatment of glaucoma, a sight-threatening disease typically characterized by elevated intraocular pressure leading to optic nerve damage. Glaucoma is currently the world’s second leading cause of blindness, and we estimate that over 60 million people worldwide have glaucoma. According to IMS Health Inc., an independent research firm, our products for the treatment of glaucoma, including Alphagan®, Alphagan® P and Lumigan®, captured approximately 17% of the worldwide glaucoma market for the first nine months of 2005.
      Our largest selling eye care pharmaceutical products are the ophthalmic solutions Alphagan® (brimonidine tartrate ophthalmic solution) 0.2% and Alphagan® P (brimonidine tartrate ophthalmic solution) 0.15%, preserved with Purite®. Alphagan® and Alphagan® P lower intraocular pressure by reducing aqueous humor production and increasing uveoscleral outflow. Alphagan® P is an improved reformulation of Alphagan® containing brimonidine, Alphagan®’s active ingredient, preserved with Purite®. We currently market Alphagan® and Alphagan® P in over 70 countries worldwide. In September 2001, we filed a New Drug Application with the U.S. Food and Drug Administration, or FDA, for a brimonidine and timolol combination designed to treat glaucoma. In March 2005, the FDA issued an approvable letter for our brimonidine and timolol combination. During the fourth quarter of 2003, we received approval from Health Canada for our

brimonidine and timolol combination, which is marketed as Combigantm. In December 2004, we received our first European approval of Combigantm in Switzerland, and in April 2005, we received marketing approval for Combigantm in the United Kingdom. In September 2005, we received a positive opinion from the European Union by way of the Mutual Recognition Process for Combigantm. The positive opinion was received in all twenty-one concerned member states in which we filed. During 2004 and 2005, we also received approvals in Brazil, Argentina, Mexico, India, Australia, Taiwan and New Zealand.
      Alphagan® and Alphagan® P combined were the third best selling glaucoma products in the world for the first nine months of 2005, according to IMS Health Inc. Combined sales of Alphagan®, Alphagan® P and Combigantm represented approximately 12% of our total consolidated sales in 2005, 13% of our total consolidated sales in 2004 and 16% of our total consolidated sales in 2003. In July 2002, based on the acceptance of Alphagan® P, we discontinued the U.S. distribution of Alphagan®. In May 2004, we entered into an exclusive licensing agreement with Kyorin Pharmaceutical Co., Ltd., under which Kyorin became responsible for the development and commercialization of Alphagan® and Alphagan® P in Japan’s ophthalmic specialty area. Kyorin subsequently sub-licensed its rights under the agreement to Senju Pharmaceutical Co., Ltd. Under the licensing agreement, Senju incurs associated costs, makes development and commercialization milestone payments, and makes royalty-based payments on product sales. We agreed to work collaboratively with Senju on overall product strategy and management. The marketing exclusivity period for Alphagan® P expired in the United States in September 2004, although we have a number of patents covering the Alphagan® P technology that extend to 2021 in the United States and 2009 in Europe, with corresponding patents pending in Europe. In May 2003, the FDA approved the first generic form of Alphagan®. Additionally, a generic form of Alphagan® is sold in a limited number of other countries, including Canada, Mexico, India, Brazil, Colombia and Argentina. See Item 3 of Part I of this report, “Legal Proceedings” and Note 12, “Commitments and Contingencies,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for further information regarding litigation involving Alphagan®. Falcon Pharmaceuticals, Ltd., an affiliate of Alcon Laboratories, Inc., is attempting to obtain FDA approval for and to launch a brimonidine product to compete with our Alphagan® P product. In August 2005, we received FDA approval to market a new formulation of Alphagan® P (brimonidine tartrate ophthalmic solution) 0.1%, preserved with Purite® and launched the product in January 2006.
      Lumigan® (bimatoprost ophthalmic solution) 0.03% is a topical treatment indicated for the reduction of elevated intraocular pressure in patients with glaucoma or ocular hypertension who are either intolerant or insufficiently responsive when treated with other intraocular pressure-lowering medications. Sales of Lumigan® represented approximately 12% of our total consolidated sales in 2005, 11% of our total consolidated sales in 2004 and 10% of our total consolidated sales in 2003. In March 2002, the European Commission approved Lumigan® through its centralized procedure. In January 2004, the European Union’s Committee for Proprietary Medicinal Products approved Lumigan® as a first-line therapy for the reduction of elevated intraocular pressure in chronic open-angle glaucoma and ocular hypertension. We currently sell Lumigan® in over 40 countries worldwide. In May 2004, we entered into an exclusive licensing agreement with Senju Pharmaceutical Co., Ltd., under which Senju became responsible for the development and commercialization of Lumigan® in Japan’s ophthalmic specialty area. Senju incurs associated costs, makes development and commercialization milestone payments and makes royalty-based payments on product sales. We agreed to work collaboratively with Senju on overall product strategy and management. In November 2003, we filed a New Drug Application with the FDA for a Lumigan® and timolol combination designed to treat glaucoma or ocular hypertension. In August 2004, we announced that the FDA issued an approvable letter regarding the Lumigan® and timolol combination, setting out the conditions, including additional clinical investigation, that we must meet in order to obtain final FDA approval. The Lumigan® and timolol combination has been filed in the European Union and is under evaluation by the European Medicines Evaluation Agency (EMEA).
      Ocular Surface Disease. In December 2002, the FDA approved Restasis® (cyclosporine ophthalmic emulsion) 0.05%, the first and currently the only prescription therapy for the treatment of chronic dry eye disease. We launched Restasis® in the United States in April 2003 under a license from Novartis for the ophthalmic use of cyclosporine. Dry eye disease is a painful and irritating condition involving abnormalities

and deficiencies in the tear film initiated by a variety of causes. The incidence of dry eye disease increases markedly with age, after menopause in women and in people with systemic diseases such as Sjogren’s syndrome and rheumatoid arthritis. Until the approval of Restasis®, physicians used lubricating tears as a temporary measure to provide palliative relief of the debilitating symptoms of dry eye disease. Effective April 19, 2005, we entered into a royalty buy-out agreement with Novartis related to Restasis® and agreed to pay $110 million to Novartis in exchange for Novartis’ worldwide rights and obligations, excluding Japan, for technology, patents and products relating to the topical ophthalmic use of cyclosporine A, the active ingredient in Restasis®. Under the royalty buy-out agreement, we will no longer be required to make royalty payments to Novartis in connection with our sales of Restasis®. In October 2005, we entered into an agreement with NPS Pharmaceuticals to promote Restasis® to rheumatologists in the United States. In June 2001, we entered into a licensing, development and marketing agreement with Inspire Pharmaceuticals, Inc. under which we obtained an exclusive license to develop and commercialize Inspire’s INS365 Ophthalmic, a treatment to relieve the signs of dry eye disease by rehydrating conjunctival mucosa and increasing non-lacrimal tear component production, in exchange for royalty payments to Inspire on sales of both Restasis® and, ultimately, INS365. In December 2003, the FDA issued an approvable letter for INS365 and also requested additional clinical data. In February 2005, Inspire announced that INS365 failed to demonstrate statistically significant improvement as compared to a placebo for the primary endpoint of the incidence of corneal clearing. Inspire also announced that INS365 achieved improvement compared to a placebo for a number of secondary endpoints. Inspire filed a New Drug Application amendment with the FDA in the second quarter of 2005. In December 2005, Inspire announced that it had received a second approvable letter from the FDA in connection with INS365.
      Ophthalmic Inflammation. Our leading ophthalmic anti-inflammatory product is Acular® (ketorolac ophthalmic solution) 0.5%. Acular® is a registered trademark of and is licensed from its developer, Syntex (U.S.A.) Inc., a business unit of Hoffmann-LaRoche Inc. Acular® is indicated for the temporary relief of itch associated with seasonal allergic conjunctivitis, the inflammation of the mucus membrane that lines the inner surface of the eyelids, and for the treatment of post-operative inflammation in patients who have undergone cataract extraction. Acular PF® was the first, and currently remains the only, unit-dose, preservative-free topical non-steroidal anti-inflammatory drug in the United States. Acular PF® is indicated for the reduction of ocular pain and photophobia following incisional refractive surgery. See Item 3 of Part I of this report, “Legal Proceedings” and Note 12, “Commitments and Contingencies,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for information regarding our successful patent infringement lawsuit against Apotex, Inc., et al. confirming the validity and enforceability of our intellectual property covering Acular®. Apotex, Inc. subsequently appealed that judgment and the United States Court of Appeals for the Federal Circuit (the Federal Circuit) left undisturbed the finding of infringement but remanded the matter for re-hearing by the district court on one issue. Subsequently, the Federal Circuit vacated the district court’s permanent injunction barring the sale of the generic product but indicated that we could request a preliminary injunction from the district court, which we obtained in January 2006 and which was extended in February 2006.
      In August 2003, we launched Acular LS® (ketorolac ophthalmic solution 0.4%), which is a version of Acular® that has been reformulated for the reduction of ocular pain, burning and stinging following corneal refractive surgery.
      Our product Pred Forte® remains a leading topical steroid worldwide based on 2005 sales. Pred Forte® has no patent protection or marketing exclusivity and faces generic competition.
      Ophthalmic Infection. A leading product in the ophthalmic anti-infective market is our Ocuflox®/ Oflox®/ Exocin® ophthalmic solution. Ocuflox® has no patent protection or marketing exclusivity and faces generic competition.
      We launched Zymar® (gatifloxacin ophthalmic solution) 0.3% in the United States in April 2003. Zymar® is a fourth-generation fluoroquinilone for the treatment of bacterial conjunctivitis. Laboratory studies have shown that Zymar® kills the most common bacteria that cause eye infections as well as specific resistant bacteria. According to Verispan, an independent research firm, Zymar® was the number one ophthalmic anti-infective prescribed by ophthalmologists in the United States in 2005.

      Allergy. The allergy market is, by its nature, a seasonal market, peaking during the spring months. We market Alocril® ophthalmic solution for the treatment of itch associated with allergic conjunctivitis. We also co-promote Elestat® (epinastine ophthalmic solution) 0.05% in the United States under an agreement with Inspire within the ophthalmic specialty area and to allergists. Elestat® is used for the prevention of itching associated with allergic conjunctivitis. Under the terms of the agreement, Inspire provided us with an up-front payment and we make payments to Inspire based on Elestat® net sales. In addition, the agreement reduced our existing royalty payment to Inspire for Restasis®. Inspire has primary responsibility for selling and marketing activities in the United States related to Elestat®. We have retained all international marketing and selling rights. We launched Elestat® in Europe under the brand names Relestat® and Purivist® during 2004, and Inspire launched Elestat® in the United States during 2004.
Neuromodulator
      Our neuromodulator product, Botox® (Botulinum Toxin Type A), is used for a wide variety of treatments which continue to expand. Botox® is accepted in many global regions as the standard therapy for indications ranging from therapeutic neuromuscular disorders and related pain to cosmetic facial aesthetics. There are currently in excess of 100 therapeutic and cosmetic uses for Botox® reported in medical literature. The versatility of Botox® is based on its localized treatment effect and approximately 17 years of safety experience in large patient groups. Marketed as Botox®, Botox® Cosmetic, Vistabel® or Vistabex®, depending on the indication and country of approval, the product is currently approved in approximately 75 countries for up to 20 unique indications. Sales of Botox® represented approximately 36%, 34% and 32% of our total consolidated sales in 2005, 2004 and 2003, respectively.
      Botox®. Botox® is used therapeutically for the treatment of certain neuromuscular disorders which are characterized by involuntary muscle contractions or spasms. The approved therapeutic indications for Botox® in the United States are as follows:
  •  blepharospasm, the uncontrollable contraction of the eyelid muscles which can force the eye closed and result in functional blindness;
 
  •  strabismus, or misalignment of the eyes, in people 12 years of age and over;
 
  •  cervical dystonia, or sustained contractions or spasms of muscles in the shoulders or neck in adults, along with associated pain; and
 
  •  severe primary axillary hyperhidrosis (underarm sweating) that is inadequately managed with topical agents.
      In many countries outside of the United States, Botox® is also approved for treating hemifacial spasm, pediatric cerebral palsy, and post-stroke focal spasticity. We are currently pursuing new indication approvals for Botox® in the United States and Europe, including headache, post-stroke focal spasticity, overactive bladder and benign prostatic hypertrophy. In April 2005, we announced plans to move forward with a large Phase III clinical trial program to investigate the safety and efficacy of Botox® as a prophylactic therapy in a subset of migraine patients with chronic daily headache, and in May 2005, we reached agreement with the FDA to enter Phase III clinical trials for Botox® to treat neurogenic overactive bladder and Phase II clinical trials for Botox® to treat idiopathic overactive bladder. In December 2005, we initiated Phase II clinical trials for Botox® to treat benign prostatic hypertrophy.
      Botox® Cosmetic. The FDA approved Botox® in April 2002 for the temporary improvement in the appearance of moderate to severe glabellar lines in adult men and women age 65 or younger. Referred to as Botox®, Botox® Cosmetic, Vistabel® or Vistabex®, depending on the country of approval, this product is designed to relax wrinkle-causing muscles to smooth the deep, persistent, glabellar lines between the brow that often develop during the aging process. Health Canada approved Botox® Cosmetic for similar use in Canada in April 2001 and for upper facial lines in November 2005. In 2005, we extended our previously launched direct-to-consumer marketing campaigns in Canada and the United States. These campaigns included television commercials and print advertising aimed at consumers and aesthetic specialty physicians. Currently,

Table of Contents

over 30 countries have approved the glabellar line indication for Botox®, Botox® Cosmetic, Vistabel® or Vistabex®, including Australia, Brazil, Canada, Denmark, France, Germany, Israel, Italy, Mexico, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. We continue to sponsor training of aesthetic specialty physicians in approved countries to further expand the base of qualified physicians using Botox®, Botox® Cosmetic, Vistabel® or Vistabex®.
      In October 2005, we entered into a long-term arrangement with GlaxoSmithKline (GSK) to develop and promote Botox® in Japan and China and to co-promote GSK’s products ImitrexSTATdose System® (sumatriptan succinate) and Amerge® (naratriptan hydrochloride) in the United States. Under the terms of the arrangement, we licensed to GSK all clinical development and commercial rights to Botox® in Japan and China, markets in which GSK has extensive commercial, regulatory and research and development resources, as well as expertise in neurology. We received an up-front payment and will receive payments for research and development and marketing support, and royalties on Japan and China Botox® sales. We also will manufacture Botox® for GSK as part of a long-term supply agreement and will work collaboratively to support GSK on new clinical development for Botox® and strategic marketing in those markets. In addition, we obtained the right to co-promote GSK’s products ImitrexSTATdose System® and Amerge® in the United States to neurologists for a 5-year period. ImitrexSTATdose System® is approved for the treatment of acute migraine in adults and for the acute treatment of cluster headache episodes. Amerge® Tablets are approved for the acute treatment of migraine attacks with and without an aura in adults. We will receive both fixed and performance payments from GSK.
Skin Care Product Line
      Our skin care product line focuses on the high growth, high margin segments of the acne and psoriasis markets, particularly in the United States and Canada.
      Tazarotene Products. We market Tazorac® gel in the United States for the treatment of plaque psoriasis, a chronic skin disease characterized by dry red patches, and acne. We also market the cream formulation of Tazorac® in the United States for the treatment of psoriasis and the topical treatment of acne. We have also engaged Pierre Fabre Dermatologie as our promotion partner for Zorac® in certain parts of Europe, the Middle East and Africa.
      Our product Avage® is a tazarotene cream indicated for the treatment of facial fine wrinkling, mottled hypo-and hyperpigmentation (blotchy skin discoloration) and benign facial lentigines (flat patches of skin discoloration) in patients using a comprehensive skin care and sunlight avoidance program. We launched Avage® in the United States in January 2003.
      In November 2003, we filed a New Drug Application with the FDA for oral tazarotene for the treatment of moderate to very severe psoriasis. In July 2004, the FDA Joint Dermatologic & Opthalmic Drugs and Drug Safety & Risk Management Advisory Committee recommended against approval of this New Drug Application, and in September 2004, the FDA issued a non-approvable letter. In late 2005, we terminated our clinical program for oral tazarotene for the treatment of moderate to very severe psoriasis based on a cost benefit and net present value analysis.
      In January 2005, we launched Prevagetm cream, containing 1% idebenone, a clinically tested antioxidant designed to reduce the appearance of fine lines and wrinkles, as well as provide protection against environmental factors including sun damage, air pollution and cigarette smoke. In May 2005, we entered into an exclusive co-marketing agreement with Elizabeth Arden, Inc. to globally market a new formulation of Prevagetm containing .5% idebenone, to leading department stores and other prestige cosmetic retailers. In September 2005, we began marketing Prevagetm MD, containing 1% idebenone, to physicians.
      Azelex®. Azelex® cream is approved by the FDA for the topical treatment of mild to moderate inflammatory acne vulgaris. We market Azelex® cream primarily in the United States.
      M.D. Forte®. We also develop and market glycolic acid-based skin care products. Our M.D. Forte® line of alpha hydroxy acid products are marketed to physicians.

      Finacea®. Through a collaboration with Intendis, Inc. (formerly known as Berlex, Inc.) we jointly promote Intendis’ topical rosacea treatment, Finacea® (azelaic acid gel 15%). Finacea® is approved by the FDA for the treatment of rosacea and has rapidly gained a leading position in the market.
International Operations
      Our international sales have represented 32.5%, 30.9% and 29.6% of our total consolidated product net sales for the years ended December 31, 2005, 2004 and 2003, respectively. Our products are sold in over 100 countries. Marketing activities are coordinated on a worldwide basis, and resident management teams provide leadership and infrastructure for customer-focused, rapid introduction of new products in the local markets.
Sales and Marketing
      We maintain a global marketing team, as well as regional sales and marketing organizations. We also engage contract sales organizations to promote certain products. Our sales efforts and promotional activities are primarily aimed at eye care professionals, neurologists, plastic surgeons and dermatologists who use, prescribe and recommend our products. We advertise in professional journals, participate in medical meetings and utilize direct mail programs to provide descriptive product literature and scientific information to specialists in the ophthalmic, dermatological and movement disorder fields. We have developed training modules and seminars to update physicians regarding evolving technology in our products. In 2005, we also utilized direct-to-consumer advertising for our Botox® Cosmetic and Restasis® products.
      Our products are sold to drug wholesalers, independent and chain drug stores, pharmacies, commercial optical chains, opticians, mass merchandisers, food stores, hospitals, ambulatory surgery centers and medical practitioners, including ophthalmologists, neurologists, dermatologists, pediatricians and plastic surgeons. As of December 31, 2005, we employed approximately 1,500 sales representatives throughout the world. We also utilize distributors for our products in smaller international markets.
      U.S. sales, including manufacturing operations, represented 67.5%, 69.1% and 70.4% of our total consolidated product net sales in 2005, 2004 and 2003, respectively. Sales to Cardinal Healthcare for the years ended December 31, 2005, 2004 and 2003 were 14.9%, 14.1% and 14.0%, respectively, of our total consolidated product net sales. Sales to McKesson Drug Company for the years ended December 31, 2005, 2004 and 2003 were 14.2%, 13.0% and 14.2%, respectively, of our total consolidated product net sales. No other country, or single customer, generates over 10% of our total product net sales.
Research and Development
      Our global research and development efforts currently focus on eye care, skin care, neuromodulators, and neurology. We also have development programs in genitourinary diseases and gastroenterology. We have a fully integrated pharmaceutical research and development organization with in-house discovery programs, including medicinal chemistry, high throughput screening, and biological sciences. We supplement our own research and development activities with our commitment to identify and obtain new technologies through in-licensing, research collaborations, joint ventures and acquisitions.
      As of December 31, 2005, we had approximately 1,100 employees involved in our research and development efforts. Our research and development expenditures for 2005, 2004 and 2003 were approximately $391.0 million, $345.6 million and $763.5 million, respectively, including expenditures on in-process research and development in connection with our 2003 acquisitions of Bardeen Sciences Company, LLC and Oculex Pharmaceuticals, Inc. Excluding in-process research and development expenditures, we have increased our annual investment in research and development by over $225 million in the past five years, dedicating approximately 20% of our investment in research and development to the discovery of new compounds. In 2004, we completed construction of a new $75 million research and development facility in Irvine, California, which provides us with approximately 175,000 square feet of additional laboratory space. In 2005, we completed construction of a new biologics facility on our Irvine, California campus at an aggregate cost of approximately $50 million.

      Our strategy is to develop innovative products to address unmet medical needs. Our top priorities include furthering our leadership in the field of neuromodulators, identifying new potential compounds for sight-threatening diseases such as glaucoma, age-related macular degeneration and macular edema, and developing novel therapies for pain, gastroenterology, and genitourinary diseases. We plan to continue to build on our strong market positions in glaucoma and therapeutic dry eye products and dermatology products for acne and psoriasis, and to explore new therapeutic areas that are consistent with our specialty pharmaceutical focus.
      Eye Care Research and Development. Our research and development efforts for the ophthalmic pharmaceuticals business focus primarily on new therapeutic products for retinal disease, glaucoma, and dry eye. As part of our focus on diseases of the retina, we acquired Oculex Pharmaceuticals, Inc. in 2003. With this acquisition, we obtained Posurdex®, a novel drug delivery technology for use with compounds to treat diseases, including macular edema and age-related macular degeneration. We have subsequently begun Phase III studies for Posurdex® for macular edema associated with diabetes and retinal vein occlusion. In March 2005, we entered into an exclusive licensing agreement with Sanwa Kagaku Kenkyusho Co., Ltd. (Sanwa) to develop and commercialize Posurdex® for the ophthalmic specialty market in Japan. Under the terms of the agreement, Sanwa is responsible for the development and commercialization of Posurdex® in Japan and associated costs. Sanwa pays us a royalty based on net sales of Posurdex® in Japan, makes development and commercialization milestone payments and reimburses us for certain expenses associated with our continuing Phase III studies outside of Japan. We will work collaboratively with Sanwa on the clinical development of Posurdex®, as well as overall product strategy and management. In September 2005, we entered into a multi-year alliance with Sirna Therapeutics, Inc. to develop Sirna-027, a novel RNAi-based therapeutic currently in clinical trials for age-related macular degeneration, and to discover and develop other novel RNAi-based therapeutics against select gene targets for ophthalmic diseases.
      Neuromodulator Research and Development. We continue to invest heavily in the research and development of neuromodulators, primarily Botox®. We are focused on both expanding the approved indications for Botox® and pursuing new neuromodulator-based therapeutics. This includes expanding the approved uses for Botox® to include treatment for spasticity, headache, brow furrow and urologic conditions including overactive bladder. In collaboration with Syntaxin, a newly formed company, whose technology was contributed by the United Kingdom government’s Health Protection Agency, we are focused on engineering neuromodulators for the treatment of severe pain. We are also continuing our investment in the areas of biologic process development and manufacturing and the next generation of neuromodulator products.
      Skin Care Research and Development. In late 2005, we terminated our clinical program for oral tazarotene for the treatment of moderate to very severe psoriasis based on a comprehensive cost benefit and net present value analysis which demonstrated that research and development resources should be directed to more valuable opportunities in our pipeline.
      Other Areas of Research and Development. We are also working to leverage our technologies in therapeutic areas outside of our current specialties, such as our Phase II clinical trials for the use of alpha agonists for the treatment of neuropathic pain. Additionally, we are conducting Phase II clinical trials for a novel proton pump inhibitor designed to reduce excess stomach acid secretion.
      In December 2002, we entered into a strategic research collaboration and license agreement with ExonHit Therapeutics. The goals of this collaboration are to identify new molecular targets based on ExonHit Therapeutics’ gene profiling DATAStm technology and to work collaboratively developing unique compounds and commercial products based on these targets. Our strategic alliance with ExonHit Therapeutics provides us with the rights to compounds developed in the fields of neurodegenerative disease, pain and ophthalmology.
      The continuing introduction of new products supplied by our research and development efforts and in-licensing opportunities are critical to our success. There are intrinsic uncertainties associated with research and development efforts and the regulatory process. We cannot assure you that any of the research projects or pending drug marketing approval applications will result in new products that we can commercialize. Delays or failures in one or more significant research projects and pending drug marketing approval applications could have a material adverse affect on our future operations.

Manufacturing
      We manufacture the majority of our commercial products in our own plants located in Waco, Texas; Westport, Ireland; and Guarulhos, Brazil. We maintain sufficient manufacturing capacity at these facilities to support forecasted demand as well as a modest safety margin of additional capacity to meet peaks of demand and sales growth in excess of expectations. We increase our capacity as required in anticipation of future sales increases. In the event of a very large or very rapid unforeseen increase in market demand for a specific product or technology, supply of that product or technology could be negatively impacted until additional capacity is brought on line. Third parties manufacture a small number of commercial products for us. However, the revenues from these products are not material to our operating results.
      We are vertically integrated into the production of plastic parts and produce our own bottles, tips and caps for use in the manufacture of our ophthalmic solutions. Additionally, we ferment, purify and characterize the botulinum toxin used in our product Botox®. With these two exceptions, we purchase all other raw materials from qualified domestic and international sources. These raw materials consist of active pharmaceutical ingredients, pharmaceutical excipients, and packaging components. Where practical, we maintain more than one supplier for each material, and we have an ongoing alternate sourcing endeavor that identifies additional sources of key raw materials. In some cases, however, most notably with active pharmaceutical ingredients, we are a niche purchaser of specialty chemicals, which, in certain cases, are sole sourced. These sources are identified in filings with regulatory agencies, including the FDA, and cannot be changed without prior regulatory approval. In these cases, we maintain inventories of the raw material itself and precursor intermediates to mitigate the risk of interrupted supply. A lengthy interruption of the supply of one of these materials could adversely affect our ability to manufacture and supply commercial product. A small number of the raw materials required to manufacture certain of our products are derived from biological sources which could be subject to contamination and recall by their suppliers. We use multiple lots of these raw materials at any one time in order to mitigate such risks. However, a shortage, contamination or recall of these products could disrupt our ability to maintain an uninterrupted commercial supply of our finished goods.
Competition
      The pharmaceutical industry is highly competitive and requires an ongoing, extensive search for technological innovation. It also requires, among other things, the ability to effectively discover, develop, test and obtain regulatory approvals for products, as well as the ability to effectively commercialize, market and promote approved products, including communicating the effectiveness, safety and value of products to actual and prospective customers and medical professionals. Numerous companies are engaged in the development, manufacture and marketing of health care products competitive with those that we manufacture. Many of our competitors have greater resources than we have. This enables them, among other things, to make greater research and development investments and spread their research and development costs, as well as their marketing and promotion costs, over a broader revenue base. Our competitors may also have more experience and expertise in obtaining marketing approvals from the FDA and other regulatory authorities. In addition to product development, testing, approval and promotion, other competitive factors in the pharmaceutical industry include industry consolidation, product quality and price, product technology, reputation, customer service and access to technical information.
      Our major eye care competitors include Alcon Laboratories, Inc., Bausch & Lomb, Pfizer, Novartis Ophthalmics and Merck & Co., Inc. For our eye care products to be successful, we must be able to manufacture and effectively market those products and persuade a sufficient number of eye care professionals to use or continue to use our current products and the new products we may introduce. Glaucoma must be treated over an extended period and doctors may be reluctant to switch a patient to a new treatment if the patient’s current treatment for glaucoma remains effective.
      Our skin care business competes against a number of companies, including among others, Dermik, a division of Sanofi-Aventis, Galderma, a joint venture between Nestle and L’Oreal, Medicis, Connetics, Novartis, Schering-Plough Corporation and Johnson & Johnson, most of which have greater resources than us. With respect to neuromodulators, until December 2000, Botox® was the only neuromodulator approved by

10


Table of Contents

the FDA. At that time, the FDA approved Myobloc®, a neuromodulator formerly marketed by Elan Pharmaceuticals and now marketed by Solstice Neurosciences Inc. We believe that Beaufour Ipsen Ltd. intends to seek FDA approval of its Dysport® neuromodulator for certain therapeutic indications, and approval of Dysport®/Reloxin® for cosmetic indications. Beaufour Ipsen has marketed Dysport® in Europe since 1991, prior to our European commercialization of Botox® in 1992. Also, Mentor Corporation is conducting clinical trials for a competing neuromodulator in the United States. In addition, we are aware of competing neuromodulators currently being developed and commercialized in Asia, Europe, South America and other markets. A Chinese entity received approval to market a botulinum toxin in China in 1997, and we believe that it has launched or is planning to launch its botulinum toxin product in other lightly regulated markets in Asia, South America and Central America. These lightly regulated markets may not require adherence to the FDA’s current Good Manufacturing Practice regulations, or cGMPs, or the regulatory requirements of the European Medical Evaluation Agency or other regulatory agencies in countries that are members of the Organization for Economic Cooperation and Development. Therefore, companies operating in these markets may be able to produce products at a lower cost than we can. In addition, Merz Pharmaceuticals received approval from German authorities for a botulinum toxin and launched its product in July 2005, and a Korean company is conducting Phase III clinical trials for a botulinum toxin in Korea. This product received exportation approval from Korean authorities in early 2005.
      In addition, we also face competition from generic drug manufacturers in the United States and internationally. For instance, Falcon Pharmaceuticals, Ltd., an affiliate of Alcon Laboratories, Inc., is currently attempting to obtain FDA approval for and to launch a brimonidine product to compete with our Alphagan® P product.
Government Regulation
      Cosmetics, drugs and biologics are subject to regulation by the FDA, state agencies and, in varying degrees, by foreign health agencies. Pharmaceutical products and biologics are subject to extensive pre- and post-market regulation by the FDA, including regulations that govern the testing, manufacturing, safety, efficacy, labeling, storage, record keeping, advertising and promotion of the products under the Federal Food, Drug, and Cosmetic Act with respect to drugs and the Public Health Services Act with respect to biologics, and by comparable agencies in a number of foreign countries. Failure to comply with applicable FDA or other requirements may result in civil or criminal penalties, recall or seizure of products, partial or total suspension of production or withdrawal of a product from the market.
      The process required by the FDA before a new drug or biologic may be marketed in the United States generally involves the following: completion of preclinical laboratory and animal testing; submission of an Investigational New Drug Application, which must become effective before clinical trials may begin; and performance of adequate and well controlled human clinical trials to establish the safety and efficacy of the proposed drug or biologic for its intended use. Clinical trials are typically conducted in three sequential phases, which may overlap, and must satisfy extensive Good Clinical Practice regulations and regulations for informed consent. Approval by the FDA of a New Drug Application, or NDA, is required prior to marketing a new drug, and approval of a Biologics License Application, or BLA, is required before a biologic may be legally marketed in the United States. To satisfy the criteria for approval, an NDA or BLA must demonstrate the safety and effectiveness of the product based on results of product development, preclinical studies and the three phases of clinical trials. Both NDAs and BLAs must also contain extensive manufacturing information, and the applicant must pass an FDA pre-approval inspection of the manufacturing facilities at which the drug or biologic is produced to assess compliance with cGMPs prior to commercialization. Satisfaction of FDA pre-market approval requirements typically takes several years and the actual time required may vary substantially based on the type, complexity and novelty of the product, and we cannot be certain that any approvals for our products will be granted on a timely basis, or at all.
      Once approved, the FDA may withdraw product approval if compliance with pre- and post-market regulatory standards is not maintained or if safety problems occur after the product reaches the marketplace. In addition, the FDA may require post-marketing clinical studies and surveillance programs to monitor the effect of approved products. The FDA may limit further marketing of the product based on the results of these

11


Table of Contents

post-market studies and programs. Drugs and biologics may be marketed only for the approved indications and in accordance with the provisions of the approved label. Further, any modifications to the drug or biologic, including changes in indications, labeling, or manufacturing processes or facilities, may require the submission of a new or supplemental NDA or BLA, which may require that we develop additional data or conduct additional preclinical studies and clinical trials.
      Any products manufactured or distributed by us or our collaborators pursuant to FDA approvals are also subject to continuing regulation by the FDA, including recordkeeping requirements and reporting of adverse experiences associated with the drug. Drug and biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing regulatory requirements, including cGMPs, which regulate all aspects of the manufacturing process and impose certain procedural and documentation requirements. Failure to comply with the statutory and legal requirements can subject a manufacturer to possible legal or regulatory action, including fines and civil penalties, suspension or delay in the issuance of approvals, seizure or recall of products, and withdrawal of approvals, any one or more of which could have a material adverse effect upon us.
      The FDA imposes a number of complex regulatory requirements on entities that advertise and promote pharmaceuticals and biologics, including, but not limited to, standards and regulations for direct-to-consumer advertising, off-label promotion, industry sponsored scientific and educational activities, and promotional activities involving the Internet. A manufacturer can make only those claims relating to safety and efficacy that are approved by the FDA. The FDA has very broad enforcement authority under the Federal Food, Drug, and Cosmetic Act, and failure to abide by these regulations can result in penalties, including the issuance of a warning letter directing us to correct deviations from FDA standards, a requirement that future advertising and promotional materials be pre-cleared by the FDA, and state and federal civil and criminal investigations and prosecutions. Physicians may prescribe legally available drugs and biologics for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties.
      Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communications regarding off-label use.
      We are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals, and the use and disposal of hazardous or potentially hazardous substances in connection with our research. In each of these areas, as above, the FDA has broad regulatory and enforcement powers, including the ability to levy fines and civil penalties, suspend or delay the issuance of approvals, seize or recall products, and withdraw approvals, any one or more of which could have a material adverse effect upon us.
      Internationally, the regulation of drugs is also complex. In Europe, our products are subject to extensive regulatory requirements. As in the United States, the marketing of medicinal products has for many years been subject to the granting of marketing authorizations by medicine agencies. Particular emphasis is also being placed on more sophisticated and faster procedures for reporting adverse events to the competent authorities. The European Union procedures for the authorization of medicinal products were amended in May 2004 and are now effective. The amended procedures are intended to improve the efficiency of operation of both the mutual recognition and centralized procedures. Additionally, new rules have been introduced or are under discussion in several areas, including the harmonization of clinical research laws and the law relating to orphan drugs and orphan indications. Outside the United States, reimbursement pricing is typically regulated by government agencies.
      The total cost of providing health care services has been and will continue to be subject to review by governmental agencies and legislative bodies in the major world markets, including the United States, which are faced with significant pressure to lower health care costs. The Medicare Prescription Drug Modernization Act of 2003 imposed certain reimbursement restrictions on our products in the United States. These reimbursement restrictions or other price reductions or controls could materially and adversely affect our revenues and financial condition. Additionally, price reductions and rebates have recently been mandated in

12


Table of Contents

several European countries, principally Germany, Italy, Spain and the United Kingdom. Certain products are also no longer eligible for reimbursement in France, Italy and Germany. Reference pricing is used in several markets around the world to reduce prices. Furthermore, parallel trade within the European Union, whereby products flow from relatively low-priced to high-priced markets, has been increasing.
      We cannot predict the likelihood or pace of any significant regulatory or legislative action in these areas, nor can we predict whether or in what form health care legislation being formulated by various governments will be passed. Medicare reimbursement rates are subject to change at any time. We also cannot predict with precision what effect such governmental measures would have if they were ultimately enacted into law. However, in general, we believe that such legislative activity will likely continue. If adopted, such measures can be expected to have an impact on our business.
Patents, Trademarks and Licenses
      We own, or are licensed under, numerous U.S. and foreign patents relating to our products, product uses and manufacturing processes. We believe that our patents and licenses are important to our business, but that with the exception of the U.S. and European patents relating to Lumigan®, Acular® and Alphagan® P, no one patent or license is currently of material importance in relation to our overall sales. The U.S. compound and ophthalmic use patents covering Lumigan® currently expire in 2015. The European patent covering Lumigan® expires in various countries between 2013 and 2017. The U.S. patent covering the commercial formulation of Acular® expires in 2009 and in 2008 in Europe. The U.S. patents covering the commercial formulation of Alphagan® P expire in 2012 and 2021 and in 2009 in Europe, with corresponding patents pending.
      Our success depends in part on our ability to obtain patents or rights to patents, protect trade secrets and other proprietary technologies and processes, operate without infringing upon the proprietary rights of others, and prevent others from infringing on our patents, trademarks, service marks and other intellectual property rights. Upon the expiration or loss of patent protection for a product, we can lose a significant portion of sales of that product in a very short period of time as other companies manufacture generic forms of our previously protected product at lower cost, without having had to incur significant research and development costs in formulating the product. In addition, the issuance of a patent is not conclusive as to its validity or as to the enforceable scope of the claims of the patent. It is impossible to anticipate the breadth or degree of protection that any such patents will afford, or that any such patents will not be successfully challenged in the future. Accordingly, our patents may not prevent other companies from developing substantially identical products. Hence, if our patent applications are not approved or, even if approved, such patents are circumvented, our ability to competitively exploit our patented products and technologies may be significantly reduced. Also, such patents may or may not provide competitive advantages for their respective products, in which case our ability to commercially exploit these products may be diminished.
      Third parties may challenge, invalidate, or circumvent our patents and patent applications relating to our products, product candidates and technologies. Challenges may result in potentially significant harm to our business. The cost of responding to these challenges and the inherent costs to defend the validity of our patents, including the prosecution of infringements and the related litigation, can require a substantial commitment of our management’s time, be costly and can preclude or delay the commercialization of products. See Item 3 of Part I of this report, “Legal Proceedings” and Note 12, “Commitments and Contingencies,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for information concerning our current intellectual property litigation.
      From time to time, we may need to obtain licenses to patents and other proprietary rights held by third parties to develop, manufacture and market our products. If we are unable to timely obtain these licenses on commercially reasonable terms, our ability to commercially exploit such products may be inhibited or prevented. See Item 1A. “Risk Factors” of this report.
      We market our products under various trademarks, for which we have both registered and unregistered trademark protection in the United States and certain countries outside the United States. We consider these trademarks to be valuable because of their contribution to the market identification of our products. Any failure to adequately protect our rights in our various trademarks and service marks from infringement, could

13


Table of Contents

result in a loss of their value to us. If the marks we use are found to infringe upon the trademark or service mark of another company, we could be forced to stop using those marks and, as a result, we could lose the value of those marks and could be liable for damages caused by an infringement. In addition to intellectual property protections afforded to trademarks, service marks and proprietary know-how by the various countries in which our proprietary products are sold, we seek to protect our trademarks, service marks and proprietary know-how through confidentiality agreements with third parties, including our partners, customers, employees and consultants. These agreements may be breached or become unenforceable, and we may not have adequate remedies for any such breach. It is also possible that our trade secrets will become known or independently developed by our competitors, resulting in increased competition for our products.
Environmental Matters
      We are subject to federal, state, local and foreign environmental laws and regulations. We believe that our operations comply in all material respects with applicable environmental laws and regulations in each country where we have a business presence. Although we continue to make capital expenditures for environmental protection, we do not anticipate any significant expenditures in order to comply with such laws and regulations that would have a material impact on our earnings or competitive position. We are not aware of any pending litigation or significant financial obligations arising from current or past environmental practices that are likely to have a material adverse effect on our financial position. We cannot assure you, however, that environmental problems relating to properties owned or operated by us will not develop in the future, and we cannot predict whether any such problems, if they were to develop, could require significant expenditures on our part. In addition, we are unable to predict what legislation or regulations may be adopted or enacted in the future with respect to environmental protection and waste disposal.
Seasonality
      Our business, taken as a whole, is not materially affected by seasonal factors, although we have noticed an historical trend with respect to sales of our Botox® product. Specifically, sales of Botox® have tended to be lowest during the first fiscal quarter, with sales during the second and third fiscal quarters being comparable and marginally higher than sales during the first fiscal quarter. Botox® sales during the fourth fiscal quarter have tended to be the highest due to patients obtaining their final therapeutic treatment at the end of the year, presumably to fully utilize deductibles and to receive additional cosmetic treatments prior to the holiday season.
Employee Relations
      At December 31, 2005, we employed approximately 5,055 persons throughout the world, including approximately 2,789 in the United States. None of our U.S.-based employees are represented by unions. We believe that our relations with our employees are generally good.

Item 1A. Risk Factors
      We operate in a rapidly changing environment that involves a number of risks. The following discussion highlights some of these risks and others are discussed elsewhere in this report. These and other risks could

16


Table of Contents

materially and adversely affect our business, financial condition, prospects, operating results or cash flows. The following risk factors are not an exhaustive list of the risks associated with our business. New factors may emerge or changes to these risks could occur that could materially affect our business.
We operate in a highly competitive business.
      The pharmaceutical industry is highly competitive and requires an ongoing, extensive search for technological innovation. It also requires, among other things, the ability to effectively discover, develop, test and obtain regulatory approvals for products, as well as the ability to effectively commercialize, market and promote approved products, including communicating the effectiveness, safety and value of products to actual and prospective customers and medical professionals.
      Many of our competitors have greater resources than we have. This enables them, among other things, to make greater research and development investments and spread their research and development costs, as well as their marketing and promotion costs, over a broader revenue base. Our competitors may also have more experience and expertise in obtaining marketing approvals from the FDA and other regulatory authorities. In addition to product development, testing, approval and promotion, other competitive factors in the pharmaceutical industry include industry consolidation, product quality and price, product technology, reputation, customer service and access to technical information.
      It is possible that developments by our competitors could make our products or technologies less competitive or obsolete. Our future growth depends, in part, on our ability to develop products which are more effective. For instance, for our eye care products to be successful, we must be able to manufacture and effectively market those products and persuade a sufficient number of eye care professionals to use or continue to use our current products and the new products we may introduce. Glaucoma must be treated over an extended period and doctors may be reluctant to switch a patient to a new treatment if the patient’s current treatment for glaucoma remains effective. Sales of our existing products may decline rapidly if a new product is introduced by one of our competitors or if we announce a new product that, in either case, represents a substantial improvement over our existing products. Similarly, if we fail to make sufficient investments in research and development programs, our current and planned products could be surpassed by more effective or advanced products developed by our competitors.
      Until December 2000, Botox® was the only neuromodulator approved by the FDA. At that time, the FDA approved Myobloc®, a neuromodulator formerly marketed by Elan Pharmaceuticals and now marketed by Solstice Neurosciences, Inc. Beaufour Ipsen Ltd. is seeking FDA approval of its Dysport® neuromodulator for certain therapeutic indications and approval of Dysport®/Reloxin® for cosmetic indications. While Beaufour Ipsen previously licensed Dysport®/Reloxin® to Inamed for the cosmetic indication in the United States, it will regain its licensed rights from Inamed in connection with our acquisition of Inamed. It is our belief that Beaufour Ipsen will likely relicense its rights to a partner in the United States, which license could include other geographic regions and indications. Beaufour Ipsen has marketed Dysport® in Europe since 1991, prior to our European commercialization of Botox® in 1992. Also, Mentor Corporation is conducting clinical trials for a competing neuromodulator in the United States. In addition, we are aware of competing neuromodulators currently being developed and commercialized in Asia, Europe, South America and other markets. A Chinese entity received approval to market a botulinum toxin in China in 1997, and we believe that it has launched or is planning to launch its botulinum toxin product in other lightly regulated markets in Asia, South America and Central America. These lightly regulated markets may not require adherence to the FDA’s current Good Manufacturing Practice, or cGMP, regulations, or the regulatory requirements of the European Medical Evaluation Agency or other regulatory agencies in countries that are members of the Organization for Economic Cooperation and Development. Therefore, companies operating in these markets may be able to produce products at a lower cost than we can. In addition, Merz Pharmaceuticals received approval from German authorities for a botulinum toxin and launched its product in July 2005, and a Korean company is conducting Phase III clinical trials for a botulinum toxin in Korea. This product received exportation approval from Korean authorities in early 2005. Our sales of Botox® could be materially and negatively impacted by this competition or competition from other companies that might obtain FDA approval or approval from other regulatory authorities to market a neuromodulator.

      If our acquisition of Inamed is consummated, our principal competitor in the United States for breast implants will be Mentor Corporation. Mentor announced that it received an “approvable letter” from the FDA for its silicone breast implants in July 2005. If Mentor receives approval to market and sell silicone breast implants in the United States before we do, their silicone breast implants would be the only approved silicone breast implants in the United States, giving Mentor a competitive advantage over us in the United States breast implant market, at least in the short term. In addition, Medicis Corporation began marketing Restylane®, a dermal filler, in January 2004. Through our purchase of Inamed, we will acquire Juvéderm®, a non-animal, hyaluronic acid-based dermal filler. Juvéderm® is not yet approved by the FDA for sale in the United States. Inamed began a clinical study of Juvéderm® in the United States during in the fourth quarter of 2004 and completed the filing of a premarket approval application with the FDA in December 2005. We cannot assure you that Inamed will receive approval to market Juvéderm® in the United States, or if Juvéderm® is approved, that Juvéderm® will offer equivalent or greater facial aesthetic benefits to competitive dermal filler products, that it will be competitive in price or gain acceptance in the marketplace.
      We also face competition from generic drug manufacturers in the United States and internationally. For instance, Falcon Pharmaceuticals, Ltd., an affiliate of Alcon Laboratories, Inc., is currently attempting to obtain FDA approval for and to launch a brimonidine product to compete with our Alphagan®P product.
Changes in the consumer marketplace and economic conditions may adversely affect sales or product margins of Botox® or Botox® Cosmetic.
      Botox® Cosmetic is a consumer product. If we fail to anticipate, identify or to react to competitive products or if consumer preferences in the cosmetic marketplace shift to other treatments for the temporary improvement in the appearance of moderate to severe glabellar lines, we may experience a decline in demand for Botox® Cosmetic. In addition, the popular media has at times in the past produced, and may continue in the future to produce, negative reports and publicity regarding the efficacy, safety or side effects of Botox® Cosmetic. Consumer perceptions of Botox® Cosmetic may be negatively impacted by these reports and for other reasons, including the use of unapproved botulinum toxins that result in injury, which may cause demand to decline.
      Demand for Botox® Cosmetic may also be materially adversely affected by changing economic conditions. Generally, the costs of cosmetic procedures are borne by individuals without reimbursement from their medical insurance providers or government programs. Individuals may be less willing to incur the costs of these procedures in weak or uncertain economic environments, and demand for Botox® Cosmetic could be adversely affected.
      Changes in applicable tax laws may adversely affect sales or product margins of Botox® or Botox® Cosmetic. Because Botox® and Botox® Cosmetic are pharmaceutical products, we generally do not collect or pay state sales or other tax on sales of Botox® or Botox® Cosmetic. We could be required to collect and pay state sales or other tax associated with prior, current or future years on sales of Botox® or Botox® Cosmetic. In addition to any retroactive taxes and corresponding interest and penalties that could be assessed, if we were required to collect or pay state sales or other tax associated with current or future years on sales of Botox® or Botox® Cosmetic, our sales of, or our product margins on, Botox® or Botox® Cosmetic could be adversely affected due to the increased cost associated with those products.
We could experience difficulties obtaining or creating the raw material needed to produce our products and interruptions in the supply of raw materials could disrupt our manufacturing and cause our sales and profitability to decline.
      The loss of a material supplier or the interruption of our manufacturing processes could adversely affect our ability to manufacture or sell many of our products. We obtain the specialty chemicals that are the active pharmaceutical ingredients in certain of our products from single sources, who must maintain compliance with the FDA’s cGMP regulations. If we experience difficulties acquiring sufficient quantities of these materials

18


Table of Contents

from our existing suppliers, or if our suppliers are found to be non-compliant with the cGMPs, obtaining the required regulatory approvals, including from the FDA, to use alternative suppliers may be a lengthy and uncertain process. A lengthy interruption of the supply of one or more of these materials could adversely affect our ability to manufacture and supply products, which could cause our sales and profitability to decline. In addition, the manufacturing process to create the raw material necessary to produce Botox® is technically complex and requires significant lead-time. Any failure by us to forecast demand for, or to maintain an adequate supply of, the raw material and finished product could result in an interruption in the supply of Botox® and a resulting decrease in sales of the product.
      If we consummate the Inamed acquisition, we will rely on a single supplier for silicone raw materials used in some of our products. We will also depend on third party manufacturers for silicone molded components and facial aesthetics product lines, with the exclusion of the bovine and human-based collagen products. These third party manufacturers must maintain compliance with FDA’s Quality System Regulation, or QSR, which sets forth the current good manufacturing practice requirements for medical devices. Any material reduction in our raw material supply or a failure by our third party manufacturers to maintain compliance with the QSR could result in decreased sales of our products and a decease in our revenues.
Our future success depends upon our ability to develop new products, and new indications for existing products, that achieve regulatory approval for commercialization.
      For our business model to be successful, we must continually develop, test and manufacture new products or achieve new indications for the use of our existing products. Prior to marketing, these new products and product indications must satisfy stringent regulatory standards and receive requisite approvals or clearances from regulatory authorities in the United States and abroad. The development, regulatory review and approval, and commercialization processes are time consuming, costly and subject to numerous factors that may delay or prevent the development, approval or clearance, and commercialization of new products, including legal actions brought by our competitors. To obtain approval or clearance of new indications or products in the United States, we must submit, among other information, the results of preclinical and clinical studies on the new indication or product candidate to the FDA. The number of preclinical and clinical studies that will be required for FDA approval varies depending on the new indication or product candidate, the disease or condition for which the new indication or product candidate is in development and the regulations applicable to that new indication or product candidate. Even if we believe that the data collected from clinical trials of new indications for our existing products or for our product candidates are promising, the FDA may find such data to be insufficient to support approval of the new indication or product. The FDA can delay, limit or deny approval of a new indication or product candidate for many reasons, including:
  •  a determination that the new indication or product candidate is not safe and effective;
  •  the FDA may interpret our preclinical and clinical data in different ways than we do;
  •  the FDA may not approve our manufacturing processes or facilities;
  •  the FDA may require us to perform post-marketing clinical studies; or
  •  the FDA may change its approval policies or adopt new regulations.
      Products that we are currently developing, other future product candidates or new indications for our existing products may or may not receive the regulatory approvals necessary for marketing or may receive such approvals only after delay or unanticipated costs. Delays or unanticipated costs in any part of the process or our inability to obtain timely regulatory approval for our products, including those attributable to, among other things, our failure to maintain manufacturing facilities in compliance with all applicable regulatory requirements, including cGMPs and QSR, could cause our operating results to suffer and our stock price to decrease. We are also required to pass pre-approval reviews and plant inspections of our and our suppliers’ facilities to demonstrate our compliance with cGMPs and QSR.
      Further, even if we receive FDA and other regulatory approvals for a new indication or product, the product may later exhibit adverse effects that limit or prevent its widespread use or that force us to withdraw the product from the market or to revise our labeling to limit the indications for which the product may be prescribed. In addition, even if we receive the necessary regulatory approvals, we cannot assure you that new

19


Table of Contents

products or indications will achieve market acceptance. Our future performance will be affected by the market acceptance of products such as Lumigan®, Alphagan® P, Combigantm, Restasis®, Acular LS®, Zymar®, Botox® and, if we consummate our acquisition of Inamed and, if approved by the FDA, Juvéderm® and breast implant products, as well as FDA approval of new indications for Botox®, and new products such as our Lumigan®/timolol combination, Posurdex® and memantine. We cannot assure you that these or any other compounds or products that we are developing for commercialization will be approved by the FDA for marketing or that we will be able to commercialize them on terms that will be profitable, or at all. If any of our products cannot be successfully or timely commercialized, our operating results could be materially adversely affected.
Our product development efforts may not result in commercial products.
      We intend to continue an aggressive research and development program. Successful product development in the pharmaceutical industry is highly uncertain, and very few research and development projects produce a commercial product. Product candidates that appear promising in the early phases of development, such as in early human clinical trials, may fail to reach the market for a number of reasons, such as:
  •  the product candidate did not demonstrate acceptable clinical trial results even though it demonstrated positive preclinical trial results;
  •  the product candidate was not effective in treating a specified condition or illness;
  •  the product candidate had harmful side effects in humans or animals;
  •  the necessary regulatory bodies, such as the FDA, did not approve the product candidate for an intended use;
  •  the product candidate was not economical for us to manufacture and commercialize;
  •  other companies or people have or may have proprietary rights to the product candidate, such as patent rights, and will not let us sell it on reasonable terms, or at all;
  •  the product candidate is not cost effective in light of existing therapeutics; and
  •  certain of our licensors or partners may fail to effectively conduct clinical development or clinical manufacturing activities.
      Several of our product candidates have failed or been discontinued at various stages in the product development process, including, but not limited to, our oral formulation of tazarotene for the treatment of moderate to very severe psoriasis. Of course, there may be other factors that prevent us from marketing a product. We cannot guarantee we will be able to produce commercially successful products. Further, clinical trial results are frequently susceptible to varying interpretations by scientists, medical personnel, regulatory personnel, statisticians, and others, which may delay, limit, or prevent further clinical development or regulatory approvals of a product candidate. Also, the length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied by product and by the intended use of a product. We expect that this will likely be the case with future product candidates and we cannot predict the length of time to complete necessary clinical trials and obtain regulatory approval.
If we are unable to obtain and maintain adequate protection for our intellectual property rights associated with the technologies incorporated into our products, our business and results of operations could suffer.
      Our success depends in part on our ability to obtain patents or rights to patents, protect trade secrets and other proprietary technologies and processes, operate without infringing upon the proprietary rights of others, and prevent others from infringing on our patents, trademarks, service marks and other intellectual property rights. Upon the expiration or loss of patent protection for a product, we can lose a significant portion of sales of that product in a very short period of time as other companies manufacture generic forms of our previously protected product at lower cost, without having had to incur significant research and development costs in formulating the product. Therefore, our future financial success may depend in part on obtaining patent protection for technologies incorporated into our products. We cannot assure you that such patents will be issued, or that any existing or future patents will be of commercial benefit. In addition, it is impossible to anticipate the breadth or degree of protection that any such patents will afford, and we cannot assure you that

20


Table of Contents

any such patents will not be successfully challenged in the future. If we are unsuccessful in obtaining or preserving patent protection, or if any of our products rely on unpatented proprietary technology, we cannot assure you that others will not commercialize products substantially identical to those products. Generic drug manufacturers are currently challenging the patents covering certain of our products and we expect that they will continue to do so in the future.
      We believe that the protection of our trademarks and service marks is an important factor in product recognition and in our ability to maintain or increase market share. If we do not adequately protect our rights in our various trademarks and service marks from infringement, their value to us could be lost or diminished. If the marks we use are found to infringe upon the trademark or service mark of another company, we could be forced to stop using those marks and, as a result, we could lose the value of those marks and could be liable for damages caused by an infringement. In addition to intellectual property protections afforded to trademarks, service marks and proprietary know-how by the various countries in which our proprietary products are sold, we seek to protect our trademarks, service marks and proprietary know-how through confidentiality agreements with third parties, including our partners, customers, employees and consultants. It is possible that these agreements will be breached or that they will not be enforceable in every instance, and that we will not have adequate remedies for any such breach. It is also possible that our trade secrets will become known or independently developed by our competitors.
      Third parties may challenge, invalidate, or circumvent our patents and patent applications relating to our products, product candidates and technologies. Challenges may result in potentially significant harm to our business. The cost of responding to these challenges and the inherent costs to defend the validity of our patents, including the prosecution of infringements and the related litigation, could be substantial and can preclude or delay commercialization of products. Such litigation also could require a substantial commitment of our management’s time. For certain of our product candidates, third parties may have patents or pending patents that they claim prevent us from commercializing certain product candidates in certain territories. Our success depends in part on our ability to obtain and defend patent rights and other intellectual property rights that are important to the commercialization of our products and product candidates. For additional information on our material patents see “Patents, Trademarks and Licenses” in Item 1 of Part I of this report, “Business.”
Importation of products from Canada and other countries into the United States may lower the prices we receive for our products.
      In the United States, some of our products are subject to competition from lower priced versions of our products and competing products from Canada, Mexico and other countries where government price controls or other market dynamics result in lower prices. Our products that require a prescription in the United States are often available to consumers in these markets without a prescription, which may cause consumers to further seek out our products in these lower priced markets. The ability of patients and other customers to obtain these lower priced imports has grown significantly as a result of the Internet, an expansion of pharmacies in Canada and elsewhere targeted to American purchasers, the increase in U.S.-based businesses affiliated with Canadian pharmacies marketing to American purchasers, and other factors. These foreign imports are illegal under current U.S. law, with the sole exception of limited quantities of prescription drugs imported for personal use. However, the volume of imports continues to rise due to the limited enforcement resources of the FDA and the U.S. Customs Service, and there is increased political pressure to permit the imports as a mechanism for expanding access to lower priced medicines.
      In December 2003, Congress enacted the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. This law contains provisions that may change U.S. import laws and expand consumers’ ability to import lower priced versions of our products and competing products from Canada, where there are government price controls. These changes to U.S. import laws will not take effect unless and until the Secretary of Health and Human Services certifies that the changes will lead to substantial savings for consumers and will not create a public health safety issue. The former Secretary of Health and Human Services did not make such a certification. However, it is possible that the current Secretary or a subsequent Secretary could make the certification in the future. As directed by Congress, a task force on drug importation

21


Table of Contents

recently conducted a comprehensive study regarding the circumstances under which drug importation could be safely conducted and the consequences of importation on the health, medical costs and development of new medicines for U.S. consumers. The task force issued its report in December 2004, finding that there are significant safety and economic issues that must be addressed before importation of prescription drugs is permitted, and the current Secretary has not yet announced any plans to make the required certification. In addition, federal legislative proposals have been made to implement the changes to the U.S. import laws without any certification, and to broaden permissible imports in other ways. Even if the changes to the U.S. import laws do not take effect, and other changes are not enacted, imports from Canada and elsewhere may continue to increase due to market and political forces, and the limited enforcement resources of the FDA, the U.S. Customs Service and other government agencies. For example, state and local governments have suggested that they may import drugs from Canada for employees covered by state health plans or others, and some already have implemented such plans.
      The importation of foreign products adversely affects our profitability in the United States. This impact could become more significant in the future, and the impact could be even greater if there is a further change in the law or if state or local governments take further steps to import products from abroad.
Our business will continue to expose us to risks of environmental liabilities.
      Our product development programs and manufacturing processes involve the controlled use of hazardous materials, chemicals and toxic compounds. These programs and processes expose us to risks that an accidental contamination could lead to noncompliance with environmental laws, regulatory enforcement actions and claims for personal injury and property damage. If an accident occurs, or if we discover contamination caused by prior operations, including by prior owners and operators of properties we acquire, we could be liable for cleanup obligations, damages and fines. The substantial unexpected costs we may incur could have a significant and adverse effect on our business and results of operations.
We may experience losses due to product liability claims, product recalls or corrections.
      The design, development, manufacture and sale of our products involve an inherent risk of product liability or other claims by consumers and other third parties. We have in the past been, and continue to be, subject to various product liability claims and lawsuits. In addition, we have in the past and may in the future recall or issue field corrections related to our products due to manufacturing deficiencies, labeling errors or other safety or regulatory reasons. We cannot assure you that we will not in the future experience material losses due to product liability claims, lawsuits, product recalls or corrections.
      If we consummate our acquisition of Inamed, we will assume Inamed’s product liability risks. Inamed has in the past and continues to be a manufacturer of breast implant products. The manufacture and sale of breast implant products entails risk of product liability claims. Historically, other breast implant manufacturers that suffered such claims in the 1990’s were forced to cease operations or even to declare bankruptcy. Additionally, Inamed is seeking to reintroduce silicone breast implants in the United States. If it obtains FDA approval to market silicone breast implants for breast augmentation, such approval may come with significant restrictions and requirements, including the need for a patient registry, follow up MRI’s, and substantial Phase IV clinical trial commitments. We also face a substantial risk of product liability claims from our current eye care, neuromodulator and skin care products and, upon our acquisition of Inamed, may face similar risks associated with Inamed’s obesity intervention and facial aesthetics products.
      Additionally, our pharmaceutical and aesthetic products may cause, or may appear to cause, serious adverse side effects or potentially dangerous drug interactions if misused or improperly prescribed. We are subject to adverse event reporting regulations that require us to report to the FDA or similar bodies in other countries if our products are associated with a death or serious injury. These adverse events, among others, could result in additional regulatory controls, such as the performance of costly post-approval clinical studies or revisions to our approved labeling, which could limit the indications or patient population for our products or could even lead to the withdrawal of a product from the market. Furthermore, any adverse publicity associated with such an event could cause consumers to seek alternatives to our products, which may cause

22


Table of Contents

our sales to decline, even if our products are ultimately determined not to have been the primary cause of the event.
Negative publicity concerning the safety of our products may harm our sales and we may be forced to withdraw products.
      Physicians and potential and existing patients may have a number of concerns about the safety of our products, including Botox®, eye care pharmaceuticals, skin care products, and, if we consummate our acquisition of Inamed, breast implants, obesity intervention products and facial dermal fillers, whether or not such concerns have a basis in generally accepted science or peer-reviewed scientific research. Negative publicity — whether accurate or inaccurate — about our products, based on, for example, news about Botox®, breast implant litigation or regulatory activities and developments, whether involving us or a competitor, or new government regulation, could materially reduce market acceptance of our products and could result in product withdrawals. In addition, significant negative publicity could result in an increased number of product liability claims, whether or not these claims have a basis in scientific fact. Furthermore, any adverse publicity associated with such an event could cause consumers to seek alternatives to our products, which may cause our sales to decline, even if our products are ultimately determined not to have been the primary cause of the event.
Health care initiatives and other cost-containment pressures could cause us to sell our products at lower prices, resulting in decreased revenues.
      Some of our products are purchased or reimbursed by state and federal government authorities, private health insurers and other organizations, such as health maintenance organizations, or HMOs, and managed care organizations, or MCOs. Third party payors increasingly challenge pharmaceutical product pricing. The trend toward managed healthcare in the United States, the growth of organizations such as HMOs and MCOs, and various legislative proposals and enactments to reform healthcare and government insurance programs, including the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or MMA, could significantly influence the manner in which pharmaceutical products are prescribed and purchased, which could result in lower prices and/or a reduction in demand for our products. For example, effective January 1, 2006, the MMA established a new Medicare outpatient prescription drug benefit under Part D. The MMA also established a competitive acquisition program, or CAP, in which physicians who administer drugs in their offices will be offered an option to acquire drugs covered under the Medicare Part B benefit from vendors who are selected in a competitive bidding process. Winning vendors have been selected based on criteria that include their bid price. Such cost containment measures and healthcare reforms could adversely affect our ability to sell our products. Under a new rule, implementation of the CAP will begin in July 2006.
      Furthermore, individual states have become increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access, importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third party payors or other restrictions could negatively and materially impact our revenues and financial condition. We encounter similar regulatory and legislative issues in most countries outside the United States.
      We expect there will continue to be federal and state laws and/or regulations, proposed and implemented, that could limit the amounts that international, federal and state governments will pay for health care products and services. The extent to which future legislation or regulations, if any, relating to the health care industry or third-party coverage and reimbursement may be enacted or what effect such legislation or regulation would have on our business remains uncertain. Such measures or other health care system reforms that are adopted could have a material adverse effect on our ability to commercialize successfully our products or could limit or eliminate our spending on development projects and affect our ultimate profitability.
      In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their

23


Table of Contents

prescription drug and other healthcare programs. This can reduce demand for our products or put pressure on our product pricing, which could negatively affect our revenues and profitability.
We are subject to risks arising from currency exchange rates, which could increase our costs and may cause our profitability to decline.
      We collect and pay a substantial portion of our sales and expenditures in currencies other than the U.S. dollar. Therefore, fluctuations in foreign currency exchange rates affect our operating results. We cannot assure you that future exchange rate movements, inflation or other related factors will not have a material adverse effect on our sales, gross profit or operating expenses.
We are subject to risks associated with doing business internationally.
      Our business is subject to certain risks inherent in international business, many of which are beyond our control. These risks include, among other things:
  •  adverse changes in tariff and trade protection measures;
  •  unexpected changes in foreign regulatory requirements, including quality standards and other certification requirements;
  •  potentially negative consequences from changes in or interpretations of tax laws;
  •  differing labor regulations;
  •  changing economic conditions in countries where our products are sold or manufactured or in other countries;
  •  differing local product preferences and product requirements;
  •  exchange rate risks;
  •  restrictions on the repatriation of funds;
  •  political unrest and hostilities;
  •  differing degrees of protection for intellectual property; and
  •  difficulties in coordinating and managing foreign operations.
      Any of these factors, or any other international factors, could have a material adverse effect on our business, financial condition and results of operations. We cannot assure you that we can successfully manage these risks or avoid their effects.
We may be subject to intellectual property litigation and infringement claims, which could cause us to incur significant expenses and losses or prevent us from selling our products.
      We cannot assure you that our products will not infringe patents or other intellectual property rights held by third parties. In the event we discover that we may be infringing third party patents or other intellectual property rights, we may not be able to obtain licenses from those third parties on commercially attractive terms or at all. We may have to defend, and have recently defended, against charges that we violated patents or the proprietary rights of third parties. Litigation is costly and time-consuming, and diverts the attention of our management and technical personnel. In addition, if we infringe the intellectual property rights of others, we could lose our right to develop, manufacture or sell products or could be required to pay monetary damages or royalties to license proprietary rights from third parties. An adverse determination in a judicial or administrative proceeding or a failure to obtain necessary licenses could prevent us from manufacturing or selling our products, which could harm our business, financial condition, prospects, results of operations and cash flows. See Item 3 of Part I of this report, “Legal Proceedings” and Note 12, “Commitments and Contingencies,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for information concerning our current intellectual property litigation.
The consolidation of drug wholesalers and other wholesaler actions could increase competitive and pricing pressures on pharmaceutical manufacturers, including us.
      We sell our pharmaceutical products primarily through wholesalers. These wholesale customers comprise a significant part of the distribution network for pharmaceutical products in the United States. This

24


Table of Contents

distribution network is continuing to undergo significant consolidation marked by mergers and acquisitions. As a result, a smaller number of large wholesale distributors control a significant share of the market. We expect that consolidation of drug wholesalers will increase competitive and pricing pressures on pharmaceutical manufacturers, including us. In addition, wholesalers may apply pricing pressure through fee-for-service arrangements, and their purchases may exceed customer demand, resulting in reduced wholesaler purchases in later quarters. We cannot assure you that we can manage these pressures or that wholesaler purchases will not decrease as a result of this potential excess buying.
We may acquire companies in the future and these acquisitions could disrupt our business.
      As part of our business strategy, we regularly consider and, as appropriate, make acquisitions of technologies, products and businesses that we believe are complementary to our business. Acquisitions typically entail many risks and could result in difficulties in integrating the operations, personnel, technologies and products of the companies acquired, some of which may result in significant charges to earnings. If we are unable to successfully integrate our acquisitions with our existing business, we may not obtain the advantages that the acquisitions were intended to create, which may materially adversely affect our business, results of operations, financial condition and cash flows, our ability to develop and introduce new products and the market price of our stock. In connection with acquisitions, we could experience disruption in our business or employee base, or key employees of companies that we acquire may seek employment elsewhere, including with our competitors. Furthermore, the products of companies we acquire may overlap with our products or those of our customers, creating conflicts with existing relationships or with other commitments that are detrimental to the integrated businesses.
Compliance with the extensive government regulations to which we are subject is expensive and time consuming, and may result in the delay or cancellation of product sales, introductions or modifications.
      Extensive industry regulation has had, and will continue to have, a significant impact on our business, especially our product development and manufacturing capabilities. All companies that manufacture, market and distribute pharmaceuticals and medical devices, including Allergan, are subject to extensive, complex, costly and evolving regulation by federal governmental authorities, principally by the FDA and the U.S. Drug Enforcement Administration, or DEA, and similar foreign and state government agencies. Failure to comply with the regulatory requirements of the FDA, DEA and other U.S. and foreign regulatory agencies may subject a company to administrative or judicially imposed sanctions, including, among others, a refusal to approve a pending application to market a new product or a new indication for an existing product. The Federal Food, Drug, and Cosmetic Act, the Controlled Substances Act and other domestic and foreign statutes and regulations govern or influence the research, testing, manufacturing, packing, labeling, storing, record keeping, safety, effectiveness, approval, advertising, promotion, sale and distribution of our products. Under certain of these regulations, we are subject to periodic inspection of our facilities, production processes and control operations and/or the testing of our products by the FDA, the DEA and other authorities, to confirm that we are in compliance with all applicable regulations, including the cGMPs and QSR regulations. The FDA conducts pre-approval and post-approval reviews and plant inspections of us and our suppliers to determine whether our record keeping, production processes and controls, personnel and quality control are in compliance with the cGMPs, the QSR and other FDA regulations. We are also required to perform extensive audits of our vendors, contract laboratories and suppliers to ensure that they are compliant with these requirements. In addition, in order to commercialize our products or new indications for an existing product, we must demonstrate that the product or new indication is safe and effective, and that our and our suppliers’ manufacturing facilities are compliant with applicable regulations, to the satisfaction of the FDA and other regulatory agencies.
      The process for obtaining governmental approval to manufacture and to commercialize pharmaceutical and medical device products is rigorous, typically takes many years and is costly, and we cannot predict the extent to which we may be affected by legislative and regulatory developments. We are dependent on receiving FDA and other governmental approvals prior to manufacturing, marketing and distributing our products. We

25


Table of Contents

may fail to obtain approval from the FDA or other governmental authorities for our product candidates, or we may experience delays in obtaining such approvals, due to varying interpretations of data or our failure to satisfy rigorous efficacy, safety and manufacturing quality standards. Consequently, there is always a risk that the FDA or other applicable governmental authorities will not approve our products, or will take post-approval action limiting or revoking our ability to sell our products, or that the rate, timing and cost of such approvals will adversely affect our product introduction plans, results of operations and stock price. Despite the time and expense exerted, regulatory approval is never guaranteed.
      Even after we obtain regulatory approval for a product candidate or new indication, we are subject to extensive regulation, including ongoing compliance with the FDA’s cGMP regulations, completion of post-marketing clinical studies mandated by the FDA, and compliance with regulations relating to labeling, advertising, marketing and promotion. In addition, we are subject to adverse event reporting regulations that require us to report to FDA if our products are associated with a death or serious injury. If we or any third party that we involve in the testing, packing, manufacture, labeling, marketing and distribution of our products fail to comply with any such regulations, we may be subject to, among other things, warning letters, product seizures, recalls, fines or other civil penalties, injunctions, suspension or revocation of approvals, operating restrictions and/or criminal prosecution. The FDA recently has increased its enforcement activities related to the advertising and promotion of pharmaceutical and biological products. In particular, the FDA has expressed concern regarding the pharmaceutical industry’s compliance with the agency’s regulations and guidance governing direct-to-consumer advertising, and has increased its scrutiny of such promotional materials. The FDA may limit or, with respect to certain products, terminate our dissemination of direct-to-consumer advertisements in the future, which could cause sales of those products to decline. Physicians may prescribe pharmaceutical, biologic and medical device products for uses that are not described in a product’s labeling or differ from those tested by us and approved by the FDA. While such “off-label” uses are common and the FDA does not regulate a physician’s choice of treatment, the FDA does restrict a manufacturer’s communications on the subject of off-label use. Companies cannot actively promote FDA-approved pharmaceutical, biologic or medical device products for off-label uses, but they may disseminate to physicians articles published in peer-reviewed journals. To the extent allowed by law, we disseminate peer-reviewed articles on our products to targeted physicians. If, however, our promotional activities fail to comply with the FDA’s regulations or guidelines, we may be subject to warnings from, or enforcement action by, the FDA or another enforcement agency.
      From time to time, legislative or regulatory proposals are introduced that could alter the review and approval process relating to our products. It is possible that the FDA or other governmental authorities will issue additional regulations further restricting the sale of our present or proposed products. Any change in legislation or regulations that govern the review and approval process relating to our current and future products could make it more difficult and costly to obtain approval for new products, or to produce, market, and distribute existing products.
If we market products in a manner that violates health care fraud and abuse laws, we may be subject to civil or criminal penalties.
      The Federal health care program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce or in return for purchasing, leasing, ordering, or arranging for the purchase, lease or order of any health care item or service reimbursable under Medicare, Medicaid or other federally financed health care programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers and formulary managers on the other. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exemption or safe harbor.
      Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to get a false claim paid. Pharmaceutical companies have been prosecuted under these laws for a

26


Table of Contents

variety of alleged promotional and marketing activities, such as allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion that caused claims to be submitted to Medicaid for non-covered off-label uses; and submitting inflated best price information to the Medicaid Rebate Program. The majority of states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. In addition, some states have laws that require pharmaceutical companies to adopt comprehensive compliance programs. For example, under California law, pharmaceutical companies must comply with both the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and the July 2002 PhRMA Code on Interactions with Healthcare Professionals.
      Sanctions under these federal and state laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs, criminal fines and imprisonment. Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. For example, we and several other pharmaceutical companies are currently subject to suits by governmental entities in several jurisdictions, including Massachusetts, New York and Alabama alleging that we and these other companies, through promotional, discounting and pricing practices reported false and inflated average wholesale prices or wholesale acquisition costs and failed to report best prices as required by federal and state rebate statutes, resulting in the plaintiffs overpaying for certain medications. If our past or present operations are found to be in violation of any of the laws described above or other similar governmental regulations to which we are subject, we may be subject to the applicable penalty associated with the violation which could adversely affect our ability to operate our business and our financial results.
If our collaborative partners do not perform, we will be unable to develop and market products as anticipated.
      We have entered into collaborative arrangements with third parties to develop and market certain products, including our partnership with GlaxoSmithKline to market Botox® in Japan and China and certain other products in the United States. We cannot assure you that these collaborations will be successful, lead to significant sales of our products in our partners’ territories or lead to the creation of additional products. If we fail to maintain our existing collaborative arrangements or fail to enter into additional collaborative arrangements, our licensing revenues and/or the number of products from which we could receive future revenues could decline.
      Our dependence on collaborative arrangements with third parties subjects us to a number of risks. These collaborative arrangements may not be on terms favorable to us. Agreements with collaborative partners typically allow partners significant discretion in marketing our products or electing whether or not to pursue any of the planned activities. We cannot fully control the amount and timing of resources our collaborative partners may devote to products based on the collaboration, and our partners may choose to pursue alternative products to the detriment of our collaboration. In addition, our partners may not perform their obligations as expected. Business combinations, significant changes in a collaborative partner’s business strategy, or its access to financial resources may adversely affect a partner’s willingness or ability to complete its obligations. Moreover, we could become involved in disputes with our partners, which could lead to delays or termination of the collaborations and time-consuming and expensive litigation or arbitration. Even if we fulfill our obligations under a collaborative agreement, our partner can terminate the agreement under certain circumstances. If any collaborative partners were to terminate or breach our agreements with them, or otherwise fail to complete their obligations in a timely manner, we could be materially and adversely affected.
Changes in financial accounting standards to share-based payments are expected to have a significant effect on our reported results.
      The Financial Accounting Standards Board recently issued a revised standard that requires that we record compensation expense in the statement of operations for share-based payments, such as employee stock

27


Table of Contents

options, using the fair value method. The adoption of the new standard is expected to have a significant effect on our reported earnings, although it will not affect our cash flows, and could adversely impact our ability to provide accurate guidance on our future reported financial results due to the variability of the factors used to estimate the values of share-based payments. As a result, our adoption of the new standard in the first quarter of fiscal 2006 could negatively affect our stock price and our stock price volatility. In addition, although we have historically provided in the notes to our financial statements pro forma earnings information showing what our results would have been had we been recording compensation expense for such awards, the amount of such expense was not reflected in our financial results. Consequently, when we begin recording such compensation expense in 2006, the period over period comparisons will be significantly affected by the inclusion of such expense in 2006 and the absence of such expense from prior periods. If investors do not appropriately consider these changes in accounting rules, the price at which our stock is traded could be adversely affected.
Unanticipated changes in our tax rates or exposure to additional income tax liabilities could affect our profitability.
      We are subject to income taxes in both the United States and numerous foreign jurisdictions. Our effective tax rate could be adversely affected by changes in the mix of earnings in countries with different statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in or interpretations of tax laws including pending tax law changes (such as the research and development credit), changes in our manufacturing activities and changes in our future levels of research and development spending. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our provision for income taxes and estimated income tax liabilities.
Our merger with Inamed may not be consummated, may not have the benefits we expect or may disrupt our business.
      The impact of our pending acquisition of Inamed, including our ability to obtain governmental approvals for the acquisition on the terms and schedule agreed to in the agreement and plan of merger executed on December 20, 2005 between Inamed and us may result in any or all of the following risks: the businesses will not be integrated successfully; the anticipated synergies from the acquisition may not be fully realized or may take longer to realize than expected; and disruption from the acquisition, which could harm relationships with our current customers, employees or suppliers and effect our pricing, spending, third-party relationships and revenues.
Antitrust authorities may attempt to delay or prevent our acquisition of Inamed.
      We made a premerger filing under the Hart Scott Rodino Act, or the HSR Act, with the Federal Trade Commission, or FTC, and the Antitrust Division of the Department of Justice, or DOJ, on November 15, 2005. On December 15, 2005, we received a request for additional information and documentary material, referred to as a second request, from the FTC, pursuant to the HSR Act, in connection with the Inamed acquisition. The effect of the second request is to extend the waiting period imposed by the HSR Act until thirty days after we have substantially complied with such request. Until the applicable waiting period under the HSR Act expires or is terminated, we may not purchase any shares of Inamed.
      In order to minimize any potential antitrust issues, we agreed to immediately divest Reloxin®, Inamed’s neuromodulator licensed from Beaufour Ipsen, in connection with the merger. Inamed and Beaufour Ipsen have entered into a termination agreement pursuant to which, subject to the consummation of our acquisition of Inamed and certain other conditions, all rights related to Reloxin® previously granted by Beaufour Ipsen to Inamed would be returned to Beaufour Ipsen, and all worldwide rights in the Reloxin® trademark would be assigned to Beaufour Ipsen. However, we cannot provide any assurance that the necessary approvals will be obtained or that there will not be any adverse consequences to our business or the business of Inamed resulting

28


Table of Contents

from conditions that could be imposed in connection with obtaining these approvals, including other divestitures or operating restrictions upon Inamed or on us following consummation of the merger. The merger is conditioned upon the receipt of all required antitrust approvals or clearances for our acquisition of Inamed, without our, Inamed’s or any of our subsidiaries being required to meet any condition or restriction that would be materially adverse to the combined company, other than the divestiture of Reloxin®, and no court or other authority prohibiting the consummation of the merger.
Uncertainties exist in integrating Inamed’s business and operations into our own.
      We intend to integrate certain of Inamed’s functions and operations into our own. Although we believe the integration will be efficiently completed, there can be no assurance that we will be successful. There will be inherent challenges in integrating our operations that could result in a delay or the failure to achieve the anticipated synergies and, therefore, any potential cost savings and increases in earnings. Issues that must be addressed in integrating the operations of Inamed into our own include, among other things:
  •  conforming standards, controls, procedures and policies, business cultures and compensation structures between the companies;
  •  conforming information technology systems;
  •  consolidating corporate and administrative infrastructures;
  •  consolidating sales and marketing operations;
  •  retaining existing customers and attracting new customers;
  •  retaining key employees;
  •  identifying and eliminating redundant and underperforming operations and assets;
  •  minimizing the diversion of management’s attention from ongoing business concerns;
  •  coordinating geographically dispersed organizations;
  •  managing tax costs or inefficiencies associated with integrating the operations of the combined company; and
  •  making any necessary modifications to operating control standards to comply with the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder.
      If we are not able to adequately address these challenges, we may be unable to successfully integrate Inamed’s operations into our own, or to realize the anticipated benefits of the integration of the two companies. Actual cost and sales synergies, if achieved at all, may be lower than we expect and may take longer to achieve than we anticipate.
Item 1B. Unresolved Staff Comments
      None.
Item 2. Properties
      Our operations are conducted in owned and leased facilities located throughout the world. We believe our present facilities are adequate for our current needs. Our headquarters and primary administrative and research facilities, which we own, are located in Irvine, California. We have two additional facilities located in California. One such facility is leased to provide raw material support and the other facility is leased to provide administrative support. We own one facility in Texas for manufacturing and warehousing.
      Outside of the United States, we own and operate two facilities for manufacturing and warehousing. One such facility is located in Brazil and the other facility is located in Ireland. Other material facilities include leased facilities for administration in Australia, Brazil, Canada, Germany, Hong Kong, Ireland, Italy, Japan, Spain and the United Kingdom; and owned facilities for administration and research and development in France.

Item 3. Legal Proceedings
      We are involved in various lawsuits and claims arising in the ordinary course of business.
      On June 6, 2001, after receiving paragraph 4 invalidity and noninfringement Hatch-Waxman Act certifications from Apotex indicating that Apotex had filed an Abbreviated New Drug Application with the FDA for a generic form of Acular®, we and Roche Palo Alto, LLC, formerly known as Syntex (U.S.A.) LLC, the holder of the Acular® patent, filed a lawsuit entitled “Syntex (U.S.A.) LLC and Allergan, Inc. v. Apotex, Inc., et al.” in the United States District Court for the Northern District of California. Following a trial, the court entered final judgment in our favor on January 27, 2004, holding that the patent at issue is valid, enforceable and infringed by Apotex’s proposed generic drug. On February 17, 2004, Apotex filed a Notice of Appeal with the United States Court of Appeals for the Federal Circuit. On May 18, 2005, the Court of Appeals for the Federal Circuit issued an opinion affirming the lower court’s ruling on inequitable conduct and claim construction and reversing and remanding the issue of obviousness. The court did not address the issue of infringement. On August 13, 2005, Apotex filed a motion to vacate the injunction pending resolution of the remand from the United States Court of Appeals for the Federal Circuit on the obviousness. On October 28, 2005, the court denied Apotex’s motion. On November 4, 2005, Apotex filed a Notice of Appeal on the court’s ruling regarding the motion to vacate injunction. On November 16, 2005, Apotex filed with the United States Court of Appeals for the Federal Circuit an Emergency Motion for Stay of Plaintiffs’ Injunction Pending Appeal. On December 15, 2005, the United States Court of Appeals for the Federal Circuit granted Apotex’s motion, ruling that the permanent injunction had been vacated by its remand to the district court. Accordingly, on December 16, 2005, we filed a motion for temporary restraining order and preliminary injunction with the United States District Court for the Northern District of California. On December 29, 2005, the court granted our motion for a temporary restraining order. In its order, the court ruled that the defendants are restrained and enjoined, pending the court’s decision as to whether a preliminary injunction should issue, from commercially manufacturing, using, offering to sell, or selling within the United States or importing into the United States, the generic version of Acular®. On February 23, 2006, the court held a hearing on our motion for preliminary injunction and on the defendants’ obviousness challenge to the validity of the patent at issue. The court extended the temporary restraining order currently in place until the court issues its order regarding the defendants’ challenge to the validity of the patent at issue based on obviousness. On June 29, 2001, we filed a separate lawsuit in Canada against Apotex similarly relating to a generic version of Acular®. A mediation in the Canadian lawsuit was held on January 4, 2005 and a settlement conference previously scheduled for April 6, 2005 was continued to July 21, 2006.
      On June 2, 2003, a complaint entitled “Klein-Becker usa, LLC v. Allergan, Inc.” was filed in the United States District Court for the District of Utah — Central Division. The complaint, as later amended, contained claims against us for intentional interference with contractual and economic relations and unfair competition under federal and Utah law. The complaint sought declaratory and injunctive relief, based on allegations that we interfered with Klein-Becker’s contractual and economic relations by dissuading certain magazines from running Klein-Becker’s advertisements for its anti-wrinkle cream. On July 30, 2003, we filed a reply and counterclaims against Klein-Becker, asserting, as later amended, claims for false advertising, unfair competition under federal and Utah law, trade libel, trademark infringement and dilution, and seeking declaratory relief in connection with Klein-Becker’s advertisements for its anti-wrinkle cream that use the heading “Better than BOTOX®?” On July 31, 2003, the court denied Klein-Becker’s application for a temporary restraining order to restrain us from, among other things, contacting magazines regarding Klein-Becker’s advertisements. On October 7, 2003, the court granted in part and denied in part our motion to dismiss Klein-Becker’s complaint, dismissing Klein-Becker’s claims for unfair competition under federal and Utah law and its motion for injunctive relief. On August 14, 2004, the court denied in its entirety Klein-Becker’s motion to dismiss our claims. On March 2, 2005, Klein-Becker filed a motion to amend the scheduling order and a motion for leave to amend the first amended complaint. On August 4, 2005, Klein-Becker filed a Motion for Partial Summary Judgment. On August 24, 2005, the court granted Klein-Becker’s motion to amend the scheduling order and Klein-Becker’s motion for leave to amend the first amended complaint. On September 16, 2005, Klein-Becker filed its second amended complaint asserting claims for cancellation of registered trademark, false advertising and unfair competition, intentional interference with potential and existing contractual relations, and seeking

30


Table of Contents

declaratory relief. On October 7, 2005, we filed our response to the second amended complaint and a motion to dismiss certain claims in Klein-Becker’s second amended complaint. On October 25, 2005, we filed a Motion for Partial Summary Judgment and a Motion for Preliminary Injunction. In response to our Motion for Partial Summary Judgment, Klein-Becker requested that it be permitted to take additional discovery, which request was granted. The hearing on Klein-Becker’s Motion for Partial Summary Judgment was heard on December 19, 2005 and the court took the motion under submission, but denied our motion for Preliminary Injunction. Subsequently, the court granted our motion to submit additional evidence in response to Klein-Becker’s Motion for Partial Summary Judgment. On February 22, 2006, the court granted our motion to dismiss Klein-Becker’s claims for cancellation of registered trademark and unfair competition under state law. The court denied our motion to dismiss as to Klein-Becker’s federal false advertising and unfair competition claim. The court also denied Klein-Becker’s motion to file a Third Amended Complaint, in which Klein-Becker attempted to add Elizabeth Arden as a party and include a claim against Elizabeth Arden and us regarding the Prevage product. The court granted our motion as to a separate Motion for Partial Summary Judgment that Klein-Becker filed. Trial is scheduled for May 8, 2006, but Klein-Becker has filed a motion to continue the trial date to October 2006.
      On July 13, 2004, we received a paragraph 4 Hatch-Waxman Act certification from Alcon, Inc. indicating that Alcon had filed a New Drug Application with the FDA for a drug containing brimonidine tartrate ophthalmic solution in a 0.15% concentration. In the certification, Alcon contends that U.S. Patent Nos. 5,424,078; 6,562,873; 6,627,210; 6,641,834; and 6,673,337, all of which are assigned to us or our wholly-owned subsidiary, Allergan Sales, LLC, and are listed in the Orange Book under Alphagan® P, are invalid and/or not infringed by the proposed Alcon product. On August 24, 2004, we filed a complaint, entitled “Allergan, Inc. and Allergan Sales, LLC v. Alcon, Inc., Alcon Laboratories, Inc., and Alcon Research, Ltd.”, against Alcon for patent infringement in the United States District Court for the District of Delaware. On September 3, 2004, Alcon filed an answer to the complaint and a counterclaim against us. On September 23, 2004, we filed a reply to Alcon’s counterclaim. On May 2, 2005, Alcon filed a Motion for Summary Judgment of Non-Infringement of U.S. Patent No. 6,673,337 and Invalidity of U.S. Patent No. 6,641,834. The court took the Motion for Summary Judgment under submission without oral argument. On July 25, 2005, Alcon filed a motion for leave to amend its answer to the complaint and counterclaim. On July 26, 2005, the court adopted our proposed claim construction. On December 8, 2005, the court denied Alcon’s Motion for Summary Judgment. On January 17, 2006, the court denied Alcon’s motion for leave to amend its answer to the complaint and counterclaim. On January 31, 2006, Alcon filed a motion for reargument or reconsideration of its motion for leave to amend its answer to the complaint and counterclaim. On February 14, 2006, the court denied Alcon’s motion. Trial is scheduled for March 6, 2006. Pursuant to the Hatch-Waxman Act, approval of Alcon’s generic New Drug Application is stayed until the earlier of (1) 30 months from the date of the paragraph 4 certification, or (2) a ruling in the patent infringement litigation in Alcon’s favor.
      On August 26, 2004, a complaint entitled “Clayworth, et al. v. Allergan, Inc., et al.” was filed in the Superior Court of the State of California for the County of Alameda. The complaint, as amended, names us and 12 other defendants and alleges unfair business practices based upon a price fixing conspiracy in connection with the reimportation of pharmaceuticals from Canada. The complaint seeks damages, equitable relief, attorney’s fees and costs. On November 22, 2004, the pharmaceutical defendants jointly filed a demurrer to the first amended complaint. On February 4, 2005, the court issued an order sustaining the pharmaceutical defendants’ demurrer and granting plaintiffs leave to further amend the first amended complaint. On February 22, 2005, the plaintiffs filed a second amended complaint to which the pharmaceutical defendants filed a demurrer. On April 19, 2005, the court sustained the pharmaceutical defendants’ demurrer and granted the plaintiffs leave to further amend the second amended complaint. On May 6, 2005, the plaintiffs filed a third amended complaint. On May 27, 2005, the pharmaceutical defendants filed a demurrer. On July 1, 2005, the court overruled in part and sustained without leave to amend in part the pharmaceutical defendants’ demurrer, dismissing the portion of plaintiffs’ third amended complaint alleging that the pharmaceutical defendants violated California’s Unfair Competition Law by charging plaintiffs more for pharmaceuticals than they charged others outside of the United States for the same pharmaceuticals. The court overruled the pharmaceutical defendants’ demurrer with respect to plaintiffs’ claim under the Cartwright Law that the pharmaceutical defendants conspired to maintain high, non-competitive prices for pharmaceuti-

cals in the United States and sought to restrict the importation of lower-priced pharmaceuticals into the United States. The pharmaceutical defendants’ response to the third amended complaint was filed on July 15, 2005. Trial is scheduled for September 25, 2006.
      On May 24, 2005, after receiving paragraph 4 invalidity and noninfringement Hatch-Waxman Act certifications from Apotex indicating that Apotex had filed an Abbreviated New Drug Application with the FDA for a generic form of Acular LS®, we and Roche Palo Alto, LLC, formerly known as Syntex (U.S.A.) LLC, the holder of the Acular LS® patent, filed a lawsuit entitled “Roche Palo Alto LLC, formerly known as Syntex (U.S.A.) LLC and Allergan, Inc. v. Apotex, Inc., et al.” in the United States District Court for the Northern District of California. In the complaint, we and Roche asked the court to find that the Acular LS® patent is valid, enforceable and infringed by Apotex’s proposed generic drug. On July 25, 2005, Apotex filed an answer to the complaint and a counterclaim against us and Roche. On August 26, 2005, we filed our response to Apotex’s counterclaim. On August 30, 2005, the court ordered this case related to the action entitled “Syntex (U.S.A.) LLC and Allergan, Inc. v. Apotex, Inc., et al.” noted above.
      We are involved in various other lawsuits and claims arising in the ordinary course of business. These other matters are, in the opinion of management, immaterial both individually and in the aggregate with respect to our consolidated financial position, liquidity or results of operations.
      Because of the uncertainties related to the incurrence, amount and range of loss on any pending litigation, investigation or claim, management is currently unable to predict the ultimate outcome of any litigation, investigation or claim, determine whether a liability has been incurred or make an estimate of the reasonably possible liability that could result from an unfavorable outcome. We believe, however, that the liability, if any, resulting from the aggregate amount of uninsured damages for any outstanding litigation, investigation or claim will not have a material adverse effect on our consolidated financial position, liquidity or results of operations. However, an adverse ruling in a patent infringement lawsuit involving us could materially affect our ability to sell one or more of our products or could result in additional competition. In view of the unpredictable nature of such matters, we cannot provide any assurances regarding the outcome of any litigation, investigation or claim to which we are a party or the impact on us of an adverse ruling in such matters.

      We did not submit any matter during the fourth quarter of the fiscal year covered by this report to a vote of security holders, through the solicitation of proxies or otherwise.

      The financial data above has been recast to reflect the results of operations and financial positions of our ophthalmic surgical and contact lens care businesses as a discontinued operation. The results of operations for our discontinued operations include allocations of certain Allergan expenses to those operations. These amounts have been allocated on the basis that is considered by management to reflect most fairly or reasonably the utilization of the services provided to, or the benefit obtained by, those operations.
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
      This financial review presents our operating results for each of the three years in the period ended December 31, 2005, and our financial condition at December 31, 2005. Except for the historical information contained herein, the following discussion contains forward-looking statements which are subject to known and unknown risks, uncertainties and other factors that may cause our actual results to differ materially from those expressed or implied by such forward-looking statements. We discuss such risks, uncertainties and other factors throughout this report and specifically under Item 1A. “Risk Factors” of this report. In addition, the following review should be read in connection with the information presented in our consolidated financial statements and the related notes to our consolidated financial statements.

Critical Accounting Policies
      We believe that the estimates, assumptions and judgments involved in the accounting policies described below have the greatest potential impact on our consolidated financial statements, so we consider these to be our critical accounting policies. Because of the uncertainty inherent in these matters, actual results could differ from the estimates we use in applying the critical accounting policies.
Revenue Recognition
      We recognize revenue from product sales when goods are shipped and title and risk of loss transfer to the customer. We have a policy to attempt to maintain average U.S. wholesaler inventory levels of our products at an amount less than eight weeks of our net sales. We generally offer cash discounts to customers for the early payment of receivables. Those discounts are recorded as a reduction of revenue and accounts receivable in the same period that the related sale is recorded. The amounts reserved for cash discounts were $1.8 million and $1.3 million at December 31, 2005 and 2004, respectively. Provisions for cash discounts deducted from consolidated sales in 2005, 2004 and 2003 were $26.6 million, $22.5 million and $20.0 million, respectively. We permit returns of product from any product line by any class of customer if such product is returned in a timely manner, in good condition and from normal distribution channels. Return policies in certain international markets provide for more stringent guidelines in accordance with the terms of contractual agreements with customers. Allowances for returns are provided for based upon our historical patterns of returns matched against the sales from which they originated, and management’s evaluation of specific factors that increase the risk of returns. The amount of allowances for sales returns accrued at December 31, 2005 and 2004 were $5.1 million and $5.8 million, respectively. Provisions for sales returns deducted from consolidated sales were $30.6 million, $25.4 million and $28.2 million in 2005, 2004 and 2003, respectively. Historical allowances for cash discounts and product returns have been within the amounts reserved or accrued, respectively.
      Additionally, we participate in various managed care sales rebate and other incentive programs, the largest of which relates to Medicaid. Sales rebate and other incentive programs also include chargebacks, which are contractual discounts given primarily to federal government agencies, health maintenance organizations, pharmacy benefits managers and group purchasing organizations. Sales rebates and incentive accruals reduce revenue in the same period that the related sale is recorded and are included in “Other accrued expenses” in our consolidated balance sheets. The amounts accrued for sales rebates and other incentive programs at December 31, 2005 and 2004 were $71.9 million and $61.4 million, respectively. The $10.5 million increase in the amount accrued for sales rebates and other incentive programs is primarily due to a difference in the timing of when payments were made against accrued amounts at December 31, 2005 compared to December 31, 2004 and an increase in the ratio of U.S. pharmaceutical product sales, principally eye care pharmaceutical products, which are subject to such rebate and incentive programs. Provisions for sales rebates and other incentive programs deducted from consolidated sales were $167.4 million, $144.7 million and $123.5 million in 2005, 2004 and 2003, respectively. The increase in the provision for sales rebates and other incentive programs during 2005 and 2004 compared to the corresponding prior year is primarily due to an increase in the ratio of U.S. pharmaceutical product sales, principally eye care pharmaceutical products, which are subject to such rebates and incentive programs. In addition, an increase in our published list prices in the United States for pharmaceutical products generally results in a higher ratio of provisions for sales rebates and other incentive programs deducted from consolidated sales. Our procedures for estimating amounts accrued for sales rebates and other incentive programs at the end of any period are based on available quantitative data and are supplemented by management’s judgment with respect to many factors, including, but not limited to, current market place dynamics, changes in contract terms, changes in sales trends, an evaluation of current laws and regulations and product pricing. Quantitatively, we use historical sales, product utilization and rebate data and apply forecasting techniques in order to estimate our liability amounts. Qualitatively, management’s judgment is applied to these items to modify, if appropriate, the estimated liability amounts. There are inherent risks in this process. For example, customers may not achieve assumed utilization levels; customers may misreport their utilization to us; and actual movements of the U.S. Consumer Price Index — Urban (CPI-U), which affect our rebate programs with U.S. federal and state

government agencies, may differ from those estimated. On a quarterly basis, adjustments to our estimated liabilities for sales rebates and other incentive programs related to sales made in prior periods have not been material and have generally been less than 0.5% of consolidated net sales. An adjustment to our estimated liabilities of 0.5% of consolidated net sales on a quarterly basis would result in an increase or decrease to net sales and earnings before income taxes of approximately $3 million to $4 million. The sensitivity of our estimates can vary by program and type of customer. Additionally, there is a significant time lag between the date we determine the estimated liability and when we actually pay the liability. Due to this time lag, we record adjustments to our estimated liabilities over several periods, which can result in a net increase to earnings or a net decrease to earnings in those periods. Material differences may result in the amount of revenue we recognize from product sales if the actual amount of rebates and incentives differ materially from the amounts estimated by management.
      We recognize license fees as other income based on the facts and circumstances of each licensing agreement. In general, we recognize income upon the signing of a license agreement that grants rights to products or technology to a third party if we have no further obligation to provide products or services to the third party after granting the license. We defer income under license agreements when we have further obligations that indicate that a separate earnings process has not culminated.
Pensions
      We sponsor various pension plans in the United States and abroad in accordance with local laws and regulations. Our pension plans in the United States account for a large majority of our pension plans’ net periodic benefit costs and projected benefit obligations. In connection with these plans, we use certain actuarial assumptions to determine the plans’ net periodic benefit costs and projected benefit obligations, the most significant of which are the expected long-term rate of return on assets and the discount rate.
      Our assumption for the expected long-term rate of return on assets in our U.S. pension plan for determining the net periodic benefit cost is 8.25% for 2005, which is the same rate used for 2004 and 2003. We determine, based upon recommendations from our pension plans’ investment advisors, the expected rate of return using a building block approach that considers diversification and rebalancing for a long-term portfolio of invested assets. Our investment advisors study historical market returns and preserve long-term historical relationships between equities and fixed income in a manner consistent with the widely-accepted capital market principle that assets with higher volatility generate a greater return over the long run. They also evaluate market factors such as inflation and interest rates before long-term capital market assumptions are determined. The expected rate of return is applied to the market-related value of plan assets. As a sensitivity measure, the effect of a 0.25% decline in the rate of return on assets assumption would increase our expected 2006 U.S. pre-tax pension benefit cost by approximately $0.8 million.
      The discount rate used to calculate our U.S. pension benefit obligations at December 31, 2005 is 5.60%, which represents a 0.35 percentage point decline from our December 31, 2004 rate of 5.95%. We determine the discount rate largely based upon an index of high-quality fixed income investments (U.S. Moody’s Aa Corporate Long Bond Yield Average) and a constructed hypothetical portfolio of high quality fixed income investments with maturities that mirror the pension benefit obligations at the plans’ measurement date. As a sensitivity measure, the effect of a 0.25% decline in the discount rate assumption would increase our expected 2006 U.S. pre-tax pension benefit costs by approximately $1.9 million and increase our U.S. pension plans’ projected benefit obligations at December 31, 2005 by approximately $15.7 million.
Income Taxes
      Income taxes are determined using an estimated annual effective tax rate, which is generally less than the U.S. federal statutory rate, primarily because of lower tax rates in certain non-U.S. jurisdictions and research and development, or R&D, tax credits available in the United States. Our effective tax rate may be subject to fluctuations during the fiscal year as new information is obtained, which may affect the assumptions we use to estimate our annual effective tax rate, including factors such as our mix of pre-tax earnings in the various tax jurisdictions in which we operate, valuation allowances against deferred tax assets, reserves for tax contingen-

36


Table of Contents

cies, utilization of R&D tax credits and changes in or interpretation of tax laws in jurisdictions where we conduct operations. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities, along with net operating loss and credit carryforwards. We record a valuation allowance against our deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce the valuation allowance against our deferred tax assets, our income tax expense will increase or decrease, respectively, in the period such determination is made.
      Valuation allowances against our deferred tax assets were $44.1 million and $51.9 million at December 31, 2005 and 2004, respectively. Changes in the valuation allowances are a component of the estimated annual effective tax rate. The decrease in the amount of valuation allowances at December 31, 2005 compared to December 31, 2004 is primarily due to a decrease in the valuation allowance due to a change in the estimate of the amount of realizable deferred tax assets in Japan stemming from the recent licensing agreement with GlaxoSmithKline, partially offset by an increase in the valuation allowance related to deferred tax assets for certain capitalized intangible assets. Material differences in the estimated amount of valuation allowances may result in an increase or decrease in the provision for income taxes if the actual amounts for valuation allowances required against deferred tax assets differ from the amounts estimated by us.
      We have not provided for withholding and U.S. taxes for the unremitted earnings of certain non-U.S. subsidiaries because we have currently reinvested these earnings indefinitely in such operations. At December 31, 2005, we had approximately $299.5 million in unremitted earnings outside the United States for which withholding and U.S. taxes were not provided. Tax expense would be incurred if these funds were remitted to the United States. It is not practicable to estimate the amount of the deferred tax liability on such unremitted earnings. Upon remittance, certain foreign countries impose withholding taxes that are then available, subject to certain limitations, for use as credits against our U.S. tax liability, if any.
      During 2005, in connection with the American Jobs Creation Act of 2004, or the Act, we repatriated $674.0 million in extraordinary dividends, as defined by the Act, from unremitted foreign earnings that were previously considered permanently reinvested by certain non-U.S. subsidiaries. The $674.0 million amount of extraordinary dividends is the qualified amount above a $53.4 million base amount determined based on our historical repatriation levels, as defined by the Act. The tax effect of the base amount of dividends is included in our estimated annual effective tax rate. Also during 2005, we decided to repatriate approximately $85.8 million in additional dividends above the base and extraordinary dividend amounts from prior and current years’ unremitted foreign earnings that were previously considered indefinitely reinvested. Based upon our repatriation activities during 2005, we recorded estimated tax liabilities of $29.9 million and $19.7 million associated with the repatriation of the $674.0 million in extraordinary dividends and the $85.8 million in additional dividends above the base and extraordinary dividend amounts, respectively.
      During 2005, we reduced our reserves for uncertain tax positions and related provision for income taxes by $24.1 million primarily due to a change in estimate resulting from the resolution of several significant uncertain income tax audit issues, including transfer prices, the deductibility of transaction costs associated with the 2002 spin-off of AMO and intangible asset issues related to certain assets of Allergan Specialty Therapeutics, Inc. and Bardeen Sciences Company, LLC, which we acquired in 2001 and 2003, respectively. The change in estimate relates to tax years currently under examination or not yet settled through expiry of the statute of limitations.
Purchase Price Allocation
      The allocation of purchase price for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed based on their respective fair values. Additionally, we must determine whether an acquired entity is considered to be a business or a set of net assets, because a portion of the purchase price can only be allocated to goodwill in a business combination.
      During 2003, we acquired Oculex Pharmaceuticals, Inc., or Oculex, and Bardeen Sciences Company, LLC, or Bardeen, for aggregate purchase prices of approximately $223.8 million and $264.6 million,

37


Table of Contents

respectively. The prices were allocated to identified assets acquired and liabilities assumed based on their estimated fair values as of the respective transaction dates. The Oculex transaction was determined to be a business combination, while the Bardeen transaction was considered to be an asset acquisition and not a business combination. Accordingly, we have provided pro forma financial information in our financial statements to reflect the effect of the Oculex transaction on our historical operating results, but have not done so for the Bardeen transaction. See Note 3, “Acquisitions,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report.
      We determined that the assets acquired from Oculex and Bardeen consisted principally of incomplete in-process research and development and that these projects had no alternative future uses in their current state. We reached this conclusion based on discussions with our business development and research and development personnel, our review of long-range product plans and our review of a valuation report prepared by an independent valuation specialist. The valuation specialist’s report reached a conclusion with regard to the fair value of the in-process research and development assets in a manner consistent with principles prescribed in the AICPA practice aid, Assets Acquired in a Business Combination to Be Used in Research and Development Activities: A Focus on Software, Electronic Devices and Pharmaceutical Industries. In connection with the acquisition of Oculex, we determined that the assets acquired also included a proprietary technology drug delivery platform which was separately valued and capitalized as core technology. We reached this conclusion based on our determination that the acquired technology had alternative future uses in its current state. We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions.
Operations
      Headquartered in Irvine, California, we are a technology-driven, global health care company that develops and commercializes specialty pharmaceutical products for the ophthalmic, neurological, dermatological and other specialty markets. We employ approximately 5,055 persons around the world. We are an innovative leader in therapeutic and over-the-counter products that are sold in more than 100 countries. Our principal markets are the United States, Europe, Latin America and Asia Pacific.
Results of Operations
      We currently operate our business on the basis of a single reportable segment — specialty pharmaceuticals. We produce a broad range of ophthalmic products for glaucoma therapy, ocular inflammation, infection, allergy and dry eye; skin care products for acne, psoriasis and other prescription and over-the-counter dermatological products; and Botox® for certain therapeutic and cosmetic indications. We provide global marketing strategy teams to ensure development and execution of a consistent marketing strategy for our products in all geographic regions that share similar distribution channels and customers.
      Management evaluates its various global product portfolios on a revenue basis, which is presented below. We also report sales performance using the non-GAAP financial measure of constant currency sales. Constant currency sales represent current period reported sales, adjusted for the translation effect of changes in average foreign exchange rates between the current period and the corresponding period in the prior year. We calculate the currency effect by comparing adjusted current period reported amounts, calculated using the monthly average foreign exchange rates for the corresponding period in the prior year, to the actual current period reported amounts. We routinely evaluate our net sales performance at constant currency so that sales results can be viewed without the impact of changing foreign currency exchange rates, thereby facilitating period-to-period comparisons of our sales. Generally, when the U.S. dollar either strengthens or weakens against other currencies, the growth at constant currency rates will be higher or lower, respectively, than growth reported at actual exchange rates.

dollar, Mexican peso, the euro and other Latin American currencies compared to the U.S. dollar. The $41.9 million increase in net sales from the impact of foreign currency changes in 2004 compared to 2003 was due primarily to the strengthening of the euro, Japanese yen, Australian dollar, British pound, Canadian dollar and Brazilian real compared to the U.S. dollar.
      The $273.6 million increase in net sales in 2005 compared to 2004 was primarily the result of increases in sales of our eye care pharmaceuticals, Botox® and skin care product lines, partially offset by a decrease in other non-pharmaceutical sales. Eye care pharmaceuticals sales increased in 2005 compared to 2004 primarily because of strong growth in sales in the United States of Restasis®, our drug for the treatment of chronic dry eye disease, an increase in sales of our glaucoma drug Lumigan®, growth in sales of our Alphagan® franchise, primarily from our international operations and new product sales from Combigantm which is in the launch phase in Canada and Brazil, a strong increase in sales of eye drop products, primarily Refresh®, growth in sales of Zymar®, a newer anti-infective, an increase in sales of Elestat®, our topical antihistamine used for the prevention of itching associated with allergic conjunctivitis, and an increase in sales of Acular LS®, our newer non-steroidal anti-inflammatory. This increase in sales was partially offset by a decrease in sales of Ocuflox®, our older generation anti-infective that is experiencing generic competition in the United States, Acular®, our older generation anti-inflammatory, and other glaucoma products. We continue to believe that generic formulations of Alphagan® will have a negative impact on future net sales of our Alphagan® franchise. We estimate the majority of the change in our eye care pharmaceutical sales was due to mix and volume changes; however, we increased the published list prices for certain eye care pharmaceutical products in the United States, ranging from three and one-half percent to nine percent, effective February 5, 2005. We increased the published U.S. list price for Lumigan® by seven percent, Restasis® by three and one-half percent and Alphagan® P by five percent. This increase in prices had a subsequent positive net effect on our U.S. sales during 2005 compared to 2004, but the actual net effect is difficult to determine due to the various managed care sales rebate and other incentive programs in which we participate. Wholesaler buying patterns and the change in dollar value of prescription product mix also affected our reported net sales dollars. We have a policy to attempt to maintain average U.S. wholesaler inventory levels of our products at an amount less than eight weeks of our net sales. At December 31, 2005, based on available external and internal information, we believe the amount of average U.S. wholesaler inventories of our products was near the lower end of our stated policy levels.
      Botox® sales increased in 2005 compared to 2004 primarily as a result of strong growth in demand in the United States and in international markets for both therapeutic and cosmetic uses. Based on internal information, we estimate that in 2005 Botox® therapeutic sales accounted for approximately 57% of total consolidated Botox® net sales and cosmetic sales accounted for approximately 43% of total consolidated Botox® net sales. Therapeutic and cosmetic net sales grew approximately 16% and 21%, respectively, in 2005 compared to 2004. Effective January 4, 2005, we increased the published price for Botox® and Botox® Cosmetic in the United States by approximately four percent, which we believe had a positive effect on our U.S. sales growth in 2005. International Botox® sales also benefited from strong sales growth in Europe, especially in Germany, the United Kingdom, Spain, Italy and the Nordics, growth in sales in smaller distribution markets serviced by our European export sales group, and an increase in sales in Canada, Mexico, Japan and Australia. We believe our worldwide market share for neuromodulators, including Botox®, is currently over 85%.
      Skin care sales increased in 2005 compared to 2004 primarily due to higher sales of Tazorac® in the United States and new product sales generated from Prevagetm antioxidant cream, which we launched in January 2005. Net sales of Tazorac®, Zorac® and Avage® increased $11.8 million, or 15.7%, to $86.9 million in 2005 compared to $75.1 million in 2004. We increased the published U.S. list price for Tazorac® by nine percent effective February 5, 2005.
      The $290.2 million increase in net sales in 2004 compared to 2003 was primarily the result of an increase in sales of our eye care pharmaceuticals and Botox® product lines and an increase in other non-pharmaceutical sales, partially offset by a decline in sales of our skin care products. Eye care pharmaceuticals sales increased in 2004 compared to 2003 primarily because of strong growth in sales of our glaucoma drug, Lumigan®, especially in the U.S. and Europe, growth in sales of Restasis®, our drug for the treatment of chronic dry eye

disease, growth in sales of eye drop products, primarily Refresh®, an increase in sales of Zymar®, a newer anti-infective, new product sales generated from Elestattm, our topical antihistamine used for the prevention of itching associated with allergic conjunctivitis that was launched in the United States in the first quarter of 2004 by our co-promotion partner, Inspire Pharmaceuticals, Inc., and an increase in sales of Acular LS®, our newer generation non-steroidal anti-inflammatory. This increase in sales was partially offset by a decrease in sales of Ocuflox® and Acular®. Our Alphagan® franchise sales also decreased in 2004 compared to 2003 due to a general decline in U.S. wholesaler demand for Alphagan® P, market share erosion from generic Alphagan® competition and an increase in the ratio of Alphagan® P sales subject to Medicaid rebates in the United States. We estimate the majority of the change in our eye care pharmaceutical sales was due to mix and volume changes; however, we increased the published list prices for certain eye care pharmaceutical products in the United States, ranging from zero to nine percent, effective January 10, 2004. We increased the published U.S. list price for Lumigan® by five percent, and we left the price of Restasis® unchanged as of the same effective date. On May 29, 2004, we increased the published U.S. list price for Restasis® by five percent. This increase in prices had a subsequent positive net effect on our U.S. sales, but the actual net effect is difficult to determine due to the various managed care sales rebate and other incentive programs in which we participate. Wholesaler buying patterns and the change in dollar value of prescription product mix also affected our reported net sales dollars. During 2004, we had a policy to attempt to maintain average U.S. wholesaler inventory levels of our products at an amount between one to two months of our net sales. At December 31, 2004, based on available external and internal information, we believe the amount of average U.S. wholesaler inventories of our products was below our stated policy levels.
      Botox® sales increased in 2004 compared to 2003 primarily as a result of strong growth in demand in the United States and international markets for both therapeutic and cosmetic uses. Based on internal information, we estimate that in 2004 Botox® therapeutic sales accounted for approximately 58% of total consolidated Botox® net sales and cosmetic sales accounted for approximately 42% of total consolidated Botox® net sales. Therapeutic and cosmetic net sales grew approximately 20% and 30%, respectively, in 2004 compared to 2003. Effective December 22, 2003, we increased the published list price for Botox® and Botox® Cosmetic in the United States by approximately seven percent, which we believe had a corresponding positive effect on our U.S. sales growth in 2004. International Botox® sales also benefited from strong sales growth in Europe, especially in France, Spain and Italy, as a result of the March 2003 launch in France of Vistabel® and the second quarter 2004 launches of Vistabel® in Spain and certain Scandinavian countries and Vistabextm in Italy, as well as an increase in sales of Botox® in smaller distributor markets serviced by our European export sales group. Vistabel® and Vistabextm are the trade names for Botox® Cosmetic in Europe and Italy, respectively. We believe our worldwide market share as of December 31, 2004 for neuromodulators, including Botox®, was over 85%.
      Skin care sales declined in 2004 compared to 2003 primarily due to a decrease in sales of Tazorac® in the United States, where it is FDA approved to treat both psoriasis and acne, and lower sales of Avage®, which we launched in the U.S. in the first quarter of 2003. Tazorac® sales declined primarily due to excess in-channel inventory at the end of 2003, which we believe was principally at the retail pharmacy level. This type of excess in-channel inventory is difficult to detect from all sources of available market data. We increased the published U.S. list price for Tazorac® and Avage® by nine percent effective January 10, 2004 and by an additional five percent effective July 31, 2004.
      The percentage of U.S. sales in 2005 as a percentage of total product net sales declined 1.6 percentage points to 67.5% compared to U.S. sales of 69.1% in 2004, due primarily to a decrease in U.S. other non-pharmaceutical sales and an increase in international Botox® and eye care pharmaceutical sales, principally in Europe, as a percentage of total product net sales. The percentage of U.S. sales in 2004 as a percentage of total product net sales declined 1.3 percentage points to 69.1% compared to U.S. sales of 70.4% in 2003, due primarily to an increase in international eye care pharmaceutical sales, principally in Europe and Asia Pacific, as a percentage of total product net sales, and a decrease in U.S. sales of skin care products, partially offset by an increase in U.S. sales of Botox® as a percentage of total product net sales.

Gross Margin
      Our gross margin percentage increased by 1.7 percentage points to 82.8% in 2005 compared to 81.1% in 2004 and decreased by 0.7 percentage points from 81.8% in 2003 to 81.1% in 2004. Our gross margin percentage increased in 2005 compared to 2004 primarily as a result of the $53.6 million decrease in other non-pharmaceutical sales, primarily contract manufacturing sales, which have a significantly lower gross margin percentage than our pharmaceutical sales. Pharmaceutical sales increased by $327.2 million in 2005 compared to 2004. This included a small increase in the percentage mix of Botox® net sales as a percentage of total net sales, which generally have a higher gross margin percentage than our other pharmaceutical product lines. The increase in gross margin percentage in 2005 was partially offset by a small decrease in the gross margin percentage of our eye care pharmaceuticals, Botox® and skin care product lines. The gross margin percentage for eye care pharmaceuticals declined slightly in 2005 compared to 2004 due primarily to an increase in the mix of international sales, which generally have a lower gross margin percentage than U.S. sales, a higher ratio of U.S. sales subject to sales rebates and other incentive programs and a negative impact from renegotiating our distribution services arrangements with our major U.S. wholesalers during 2005. The small decline in gross margin percentage for our Botox® product line in 2005 compared to 2004 was due primarily to an increase in the mix of international sales, which generally have a lower gross margin percentage than U.S. Botox® net sales, partially offset by the published price increase in January 2005 for Botox® and Botox® Cosmetic in the United States. The decline in gross margin percentage for skin care net sales in 2005 compared to 2004 is primarily due to new product sales of Prevagetm, which have a lower gross margin percentage than our other prescription skin care products. Gross margin in dollars increased in 2005 compared to 2004 by $260.7 million, or 15.7%, as a result of the 13.4% increase in net sales and the 1.7 percentage point increase in gross margin percentage.
      Our gross margin percentage decreased in 2004 compared to 2003 primarily as a result of a decrease in gross margin percentage for eye care pharmaceuticals, the Botox® product line and skin care products, partially offset by an increase in gross margin percentage for contract manufacturing sales to AMO and an increase in the mix of Botox® sales. Net sales of Botox®, which generally have a higher gross margin percentage than our other pharmaceutical product lines, represented a greater percentage of 2004 net sales compared to 2003. The gross margin percentage for eye care pharmaceuticals declined in 2004 compared to 2003 due to an increase in the percentage of net sales derived from international sales, which generally have a lower gross margin percentage than U.S. sales, a higher ratio of U.S. sales subject to sales rebates and other

incentive programs, especially Medicaid, and products with higher royalty rates payable to third parties. The gross margin percentage for our Botox® product line experienced a small decline in 2004 compared to 2003 due primarily to lower gross margins in Latin America resulting from less favorable foreign exchange transactions that affected cost of sales in 2004 compared to 2003. The gross margin percentage for contract manufacturing sales improved primarily due to an increase in U.S. dollar denominated pricing allowed under the manufacturing and supply agreement with AMO at the beginning of our 2004 fiscal year and certain annual contract manufacturing cost recoveries allowed under the manufacturing and supply agreement with AMO.
Research Services Margin
      We have historically recognized research service revenues and costs associated with various contract research and development arrangements. Research service revenues and costs declined in 2004 compared to 2003 as a result of our acquisition of Bardeen in 2003. Prior to the Bardeen acquisition, we performed research and development services on compounds owned by Bardeen pursuant to a research and development services agreement between us and Bardeen. Since May 16, 2003, we have not been a party to any contract research and development arrangements similar to those previously reported. See Note 3, “Acquisitions,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for further disclosure regarding research service revenues and related research costs associated with our research and development services agreements with Bardeen.
Selling, General and Administrative
      Selling, general and administrative, or SG&A, expenses increased 17.3% in 2005 to $913.9 million, or 39.4% of net sales, compared to $778.9 million, or 38.1% of net sales, in 2004 and by 11.7% in 2004 to $778.9 million, or 38.1% of net sales, compared to $697.2 million, or 39.7% of net sales, in 2003. SG&A expenses increased $135.0 million in 2005 compared to 2004. The increase in SG&A expenses in 2005 compared to 2004 was primarily a result of an increase in promotion costs associated with direct-to-consumer advertising in the United States for Restasis®, Botox® Cosmetic and to a lesser extent the hyperhidrosis indication for Botox®, an increase in selling expenses, principally personnel costs, and marketing expenses supporting the increase in consolidated sales, especially for Restasis®, Botox® and Botox® Cosmetic, a small increase in costs of providing product samples, and higher general and administrative expenses, primarily incentive compensation, legal costs, information services, corporate development expenses and charitable donations. We made a $2.0 million contribution to the Allergan Foundation in the third fiscal quarter of 2005. SG&A expenses also increased due to an increase in co-promotion costs related to sales of Elestat®, costs associated with expanding our Botox® sales force in Europe and our eye care pharmaceuticals and Botox® sales forces in the United States, and the non-recurrence of a favorable settlement of a patent dispute amounting to $2.4 million in the first quarter of 2004. SG&A expenses were also negatively impacted in 2005 by implementation and transition related expenses and duplicate operating expenses associated with the restructuring and streamlining of our European operations, which totaled $3.8 million, and by an increase in the translated U.S. dollar value of foreign currency denominated expenses, especially in Europe and Latin America. This increase in SG&A expenses during 2005 compared to 2004 was partially offset by a $7.9 million pre-tax gain on the sale of our contact lens care and surgical products distribution business in India to a subsidiary of AMO, a $5.7 million pre-tax gain on the sale of assets primarily used for contract manufacturing and the former distribution of AMO related products at our manufacturing facility in Ireland and $7.6 million of reimbursement income earned from services provided in connection with contractual agreements related to the development of Posurdex® for the ophthalmic specialty market in Japan and the development and promotion of Botox® in Japan and China.
      SG&A expenses increased $81.7 million in 2004 compared to 2003. The increase in SG&A expenses in 2004 compared to 2003 was primarily a result of higher selling and marketing expenses, principally personnel costs, supporting the increase in consolidated sales, especially for Botox®, Restasis®, Lumigan® and Zymar® in the United States and Botox®, Vistabel®, Vistabextm and Lumigan® sales in Europe, an increase in promotion costs primarily associated with direct-to-consumer advertising for Restasis® in the United States, an increase

43


Table of Contents

in co-promotion costs related to sales of Elestattm, and higher general and administrative expenses, primarily corporate insurance, Sarbanes-Oxley compliance, personnel and facilities costs. These increases were partially offset by a favorable $2.4 million settlement during the first quarter of 2004 relating to a patent dispute covering the use of botulinum toxin type B for cervical dystonia and higher miscellaneous co-promotion and royalty income. SG&A expenses in 2004 were also negatively impacted by an increase in the translated U.S. dollar value of foreign currency denominated expenses, especially in Europe, compared to the same periods in 2003.
      As a percentage of net sales, SG&A expenses increased in 2005 compared to 2004 due primarily to higher promotion and marketing expenses, and general and administrative expenses as a percentage of net sales, partially offset by lower selling expenses, higher miscellaneous operating income and the pre-tax gains from the sale of assets as a percentage of net sales. SG&A expenses as a percentage of net sales declined in 2004 compared to 2003, due primarily to lower promotion, product samples and marketing expenses, as a percentage of net sales, despite the aggregate increase in expense dollars. General and administrative expenses and selling expenses as a percentage of net sales were approximately the same in 2004 compared to 2003.
      Based on the achievement of actual 2005 performance metrics as measured against pre-established performance targets specified in our 2005 Management Bonus Plan, approximately 300 of our participating 8E employees and above became eligible to receive grants in February 2006 of service-vested restricted stock and/or restricted stock units of our Company, each generally with two year cliff vesting requirements from the date of grant. On February 2, 2006, we granted a total of 52,599 shares of restricted stock and restricted stock units with a fair value of $5.9 million to the eligible employees. We recognized estimated compensation costs of $1.9 million in 2005 related to these restricted stock and restricted unit grants, and we expect to amortize the remaining fair value of $4.0 million over the requisite future service period.
Research and Development
      Research and development expenses increased in 2005 by $45.4 million to $391.0 million, or 16.9% of net sales, compared to $345.6 million, or 16.9% of net sales, in 2004. Research and development expenses decreased in 2004 by $417.9 million to $345.6 million, or 16.9% of net sales, compared to $763.5 million, or 43.5% of net sales, in 2003. Research and development expenses do not include research and development spending performed under contract with Bardeen in 2003. See Note 3, “Acquisitions,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report. Research and development expenses in 2003 include charges totaling $458.0 million related to acquired in-process research and development assets associated with the 2003 purchases of Bardeen and Oculex, which we determined were not yet complete and had no alternative future uses in their current state. A further discussion of the acquisitions of Bardeen and Oculex is provided under “Liquidity and Capital Resources — Bardeen Sciences Company, LLC and Oculex Pharmaceuticals, Inc.” and Note 3, “Acquisitions,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report. Excluding the effect of the $458.0 million in-process research and development charges in 2003, research and development spending increased in 2004 by $40.1 million to $345.6 million, or 16.9% of net sales, compared to $305.5 million, or 17.4% of net sales, in 2003.
      Research and development spending increased in 2005 compared to 2004 primarily as a result of higher rates of investment in our eye care pharmaceuticals and Botox® product lines and new technologies, partially offset by lower spending for our skin care product line. Spending increases in 2005 compared to 2004 were primarily driven by an increase in clinical trial costs associated with our Posurdex® technology and certain Botox® indications for overactive bladder and migraine headache. Also included in our spending for research and development in 2005 is $7.4 million in costs associated with two new third party technology license and development agreements associated with in-process technologies and $3.0 million related to the buy-out of a license agreement with Johns Hopkins University associated with ongoing Botox® research activities. Research and development spending increased in 2004 compared to 2003, excluding the effect of the in-process research and development charges in 2003, primarily as a result of higher rates of investment in our eye care pharmaceuticals and Botox® product lines and new technologies, partially offset by a decline in spending for our skin care product line. Research and development spending in 2004 compared to 2003

increased most significantly in eye care pharmaceuticals due to increased spending for technologies not currently commercialized by us, including technologies acquired in 2003 from the acquisitions of Oculex and Bardeen.
Restructuring Charges and Transition/Duplicate Operating Expenses
Restructuring and Streamlining of Operations in Japan
      On September 30, 2005 we entered into a long-term agreement with GlaxoSmithKline (GSK) to develop and promote Botox® in Japan and China. Under the terms of this agreement, we licensed to GSK all clinical development and commercial rights to Botox® in Japan and China. As a result of entering into this agreement, we initiated a plan in October 2005 to restructure and streamline our operations in Japan. The restructuring seeks to optimize the efficiencies of a third party license and distribution business model and align our operations in Japan with our reduced role in research and development and commercialization activities under the agreement with GSK.
      We have incurred, and anticipate that we will continue to incur, restructuring charges relating to one-time termination benefits, contract termination costs and other asset-related expenses in connection with the restructuring. We currently estimate that the pre-tax charges resulting from the restructuring will be between $3.0 million and $5.0 million. We began to incur these amounts in the fourth quarter of 2005 and expect to continue to incur them up through and including the second quarter of 2006. Substantially all of the pre-tax charges are expected to be cash expenditures.
      During the fourth quarter of 2005, we recorded pre-tax restructuring charges of $2.3 million. The restructuring charges primarily consist of one-time termination benefits, contract termination costs and other asset-related expenses. Cumulative charges for employee severance as shown in the table below relate to 65 employees of which 55 were severed as of December 31, 2005.

Restructuring and Streamlining of European Operations
      Effective January 2005, our Board of Directors approved the initiation and implementation of a restructuring of certain activities related to our European operations. The restructuring seeks to optimize operations, improve resource allocation and create a scalable, lower cost and more efficient operating model for our European research and development (R&D) and commercial activities. Specifically, the restructuring involves moving key European R&D and select commercial functions from our Mougins, France and other European locations to our Irvine, California, High Wycombe, U.K. and Dublin, Ireland facilities and streamlining functions in our European management services group.
      We have incurred, and anticipate that we will continue to incur, restructuring charges and charges relating to severance, relocation and one-time termination benefits, payments to public employment and training programs, transition and duplicate operating expenses, contract termination costs and capital and other asset-related expenses in connection with the restructuring. We currently estimate that the pre-tax charges resulting from the restructuring, including transition and duplicate operating expenses, will be between $46 million and $51 million and capital expenditures will be between $3 million and $4 million. Of the total

amount of pre-tax charges and capital expenditures, approximately $43 million to $48 million are expected to be cash expenditures.
      The foregoing estimates are based on assumptions relating to, among other things, a reduction of approximately 155 positions, principally R&D and selling, general and administrative positions in the affected European locations. These workforce reduction activities began in the first quarter of 2005 and are expected to be substantially completed by the close of the second quarter of 2006. Charges associated with the workforce reduction, including severance, relocation and one-time termination benefits, and payments to public employment and training programs, are currently expected to total approximately $30 million to $31 million.
      Estimated charges include approximately $11 million to $13 million for contract and lease termination costs and asset write-offs (primarily for accelerated amortization related to leasehold improvements in facilities to be exited) and a loss on the possible sale of our Mougins facility. We began to record these costs in the fourth quarter of 2005 and expect them to continue up through and including the second quarter of 2006.
      Estimated transition related expenses include, among other things, legal, consulting, recruiting, information system implementation costs and taxes. We also expect to incur duplicate operating expenses during the transition period to ensure that job knowledge and skills are properly transferred to new employees. Transition and duplicate operating expenses are currently estimated to total approximately $5 million to $7 million. We began to record these costs in the first quarter of 2005 and expect them to continue up through and including the second quarter of 2006.
      We expect to incur additional capital expenditures for leasehold improvements (primarily at a new facility in the United Kingdom to accommodate increased headcount). These capital expenditures are currently estimated to be between approximately $3 million and $4 million. We began to record these expenditures in the third quarter of 2005 and expect them to continue up through and including the second quarter of 2006.
      During the year ended December 31, 2005, we recorded pre-tax restructuring charges of $28.9 million related to the restructuring of our European operations. The restructuring charges primarily consist of employee severance, one-time termination benefits, employee relocation and other costs. The following table presents the cumulative restructuring activities through December 31, 2005:
                         
    Employee   Other    
    Severance   Costs   Total

      Employee severance in the preceding table relates to 155 employees, of which 67 were severed as of December 31, 2005. Employee severance charges were based on social plans in France and Italy, and our severance practices for employees in the other affected European countries. During 2005, we also recorded $5.6 million of transition/duplicate operating expenses associated with the European restructuring activities. Transition/duplicate operating expenses consisted primarily of salaries, travel, communications, recruitment and consulting costs. Transition/duplicate operating expenses of $0.3 million in cost of sales, $3.8 million in selling, general and administrative expenses and $1.5 million in research and development expenses have been included in our consolidated statements of operations for the year ended December 31, 2005.
Termination of Manufacturing and Supply Agreement with Advanced Medical Optics
      In October 2004, our Board of Directors approved certain restructuring activities related to the termination in June 2005 of our manufacturing and supply agreement with AMO. Under the manufacturing and supply agreement, which was entered into in connection with the AMO spin-off, we agreed to

manufacture certain contact lens care products and VITRAX, a surgical viscoelastic, for AMO for a period of up to three years ending in June 2005. As part of the termination of the manufacturing and supply agreement, we eliminated certain manufacturing positions at our Westport, Ireland; Waco, Texas; and Guarulhos, Brazil manufacturing facilities.
      As of December 31, 2005, we recorded cumulative pre-tax restructuring charges of $21.6 million related to the termination of the manufacturing and supply agreement. These charges primarily include statutory severance and one-time termination benefits related to the reduction in our workforce of 323 employees and the write-off of assets previously used for contract manufacturing. The pre-tax charges are net of tax credits received under qualifying government-sponsored employment programs.
      As of December 31, 2005, we had completed substantially all activities related to the termination of the manufacturing and supply agreement. We expect to record an additional $2.0 million to $3.0 million in pre-tax restructuring charges during the first three quarters of 2006 to complete the refurbishment of facilities previously used for contract manufacturing. Approximately $21.0 million of the total restructuring charges are expected to be cash expenditures.
      The following table presents the cumulative restructuring activities through December 31, 2005 resulting from the scheduled termination of the manufacturing and supply agreement with AMO:

      The remaining balance at December 31, 2005 is comprised of accrued one-time termination benefits of $0.1 million. Included in other costs within the table above is $0.2 million of inventory write-offs that have been recorded as a component of “Cost of sales” in the consolidated statements of operations.
      During the year ended December 31, 2005, we reduced by $1.6 million the remaining balance of other accrued costs associated with restructuring costs and asset write-offs previously recorded in connection with the spin-off of AMO in 2002. This reduction in other accrued costs was included in “Restructuring charge (reversal), net” for the year ended December 31, 2005. At December 31, 2005, there were no remaining accrued costs associated with the 2002 spin-off of AMO.
Operating Income
      Our operating income was $570.9 million, or 24.6% of product net sales in 2005, compared to operating income of $527.4 million, or 25.8% of product net sales in 2004, and an operating loss of $23.7 million, or (1.3)% of product net sales in 2003. The $43.5 million increase in operating income in 2005 compared to 2004 was due primarily to the $260.7 million increase in gross margin, partially offset by the $135.0 million increase in SG&A expenses, the $45.4 million increase in research and development expenses and the $36.8 million increase in restructuring charges. The $551.1 million increase in operating income in 2004 compared to 2003 was due primarily to the $223.8 million increase in gross margin and the $417.9 million decrease in research and development expenses, partially offset by the increase in SG&A expenses of $81.7 million and an increase in restructuring charges of $7.4 million.

Non-Operating Income and Expenses
      Total net non-operating income in 2005 was $28.3 million compared to net non-operating income of $4.7 million in 2004 and net non-operating expenses of $5.8 million in 2003. Interest income in 2005 was $35.4 million compared to interest income of $14.1 million in 2004. Interest income in 2004 was $14.1 million compared to interest income of $13.0 million in 2003. The increase in interest income in 2005 compared to 2004 was primarily due to higher average cash equivalent balances earning interest of approximately $323 million and an increase in average interest rates earned on all cash equivalent balances earning interest of approximately 1.82% in 2005 compared to 2004. Interest income in 2005 also benefited from the recognition of $2.1 million of statutory interest income related to the expected recovery of previously paid state income taxes, which became recoverable due to a favorable state court decision that became final during 2004. The increase in interest income in 2004 compared to 2003 was primarily due to higher average cash equivalent balances earning interest of approximately $246 million, partially offset by lower average interest rates earned on all cash equivalent balances earning interest of approximately 0.42% in 2004 compared to 2003. Interest income also increased in 2004 compared to 2003 due to statutory interest income accrued in 2004 related to a refund claim for previously paid state income taxes. Interest expense decreased to $12.4 million in 2005 compared to interest expense of $18.1 million in 2004, primarily due to a reversal during 2005 of $7.3 million of previously accrued statutory interest expense associated with a reduction in accrued income taxes payable related to the resolution of several significant uncertain income tax audit issues, and the non-recurrence in 2005 of a $3.1 million adjustment to interest expense recorded in 2004 related to the accelerated amortization of certain debt issuance costs as discussed below in the analysis of interest expense in 2004 compared to 2003. This decrease in interest expense in 2005 was partially offset by an increase in interest expense related to additional foreign borrowings in Ireland required to effectuate the repatriation of dividends that occurred during the third quarter of 2005. Interest expense increased $2.5 million to $18.1 million in 2004 compared to $15.6 million in 2003, primarily due to an increase in the amortization of deferred debt issuance costs related to our outstanding zero coupon convertible senior notes due 2022, or Senior Notes, partially offset by lower other statutory interest expense. During the third quarter of 2004, we accelerated our amortization of debt issuance costs to a more conservative view, electing to amortize such costs related to our Senior Notes over the five year period from date of issuance in November 2002 to the first noteholder put date in November 2007 instead of over the 20 year life of the Senior Notes. As a result, we recorded an adjustment for the cumulative difference in amortized debt issuance costs as of the beginning of the third quarter of 2004 of $3.1 million. The impact of this adjustment is immaterial to our consolidated financial statements for the year ended December 31, 2004.
      Gains on investments of $0.8 million in 2005 and $0.3 million in 2004 resulted from the sale of miscellaneous third party equity investments. At December 31, 2005, we had a carrying amount of $8.3 million (with a cost basis of $5.3 million) in third party equity investments with public and privately held companies. These investments are subject to review for other than temporary declines in fair value on a quarterly basis.
      During 2005, we recorded a net unrealized gain on derivative instruments of $1.1 million compared to net unrealized losses of $0.4 million during 2004 and net unrealized losses of $0.3 million in 2003. Other net income was $3.4 million in 2005 compared to other net income of $8.8 million in 2004 and other net expenses of $2.9 million in 2003. In 2005, Other, net primarily includes a gain of $3.5 million for the receipt of a technology transfer fee related to the assignment of a third party patent licensing arrangement covering the use of botulinum toxin type B for cervical dystonia and net realized losses from foreign currency transactions of $1.0 million. In 2004, Other, net primarily includes a realized gain of $6.5 million related to an agreement with ISTA Pharmaceuticals, Inc. to revise their previous Vitrase® product collaboration agreement and a realized gain of $5.0 million for the receipt of a technology transfer fee related to the assignment of a third party patent licensing arrangement covering the use of botulinum toxin type B for cervical dystonia. In 2003, Other, net primarily includes $1.8 million of expenses related to accruals for the settlement of non-income foreign tax compliance matters in Latin America and Europe, and $0.9 million of expenses related to the write-off of unamortized debt origination fees associated with the retirement of the remaining balance of our zero coupon

Income Taxes
      Our effective tax rate in 2005 was 32.1% compared to the effective tax rate of 28.9% in 2004. Included in our operating income in 2005 are pre-tax restructuring charges of $43.8 million, transition/duplicate operating expenses associated with the European restructuring activities of $5.6 million, a gain of $7.9 million on the sale of our distribution business in India and a gain of $5.7 million on the sale of assets used primarily for contract manufacturing of AMO products. In 2005, we recorded income tax benefits of $7.6 million related to the pre-tax restructuring charges and $1.1 million related to transition/duplicate operating expenses, and a provision for income taxes of $1.7 million on the gain on sale of the distribution business in India and $0.6 million on the gain on sale of assets used primarily for contract manufacturing. Included in the provision for income taxes in 2005 is an estimated $29.9 million income tax provision associated with our decision to repatriate $674.0 million in extraordinary dividends as defined by the American Jobs Creation Act of 2004, or the Act, from unremitted foreign earnings that were previously considered indefinitely reinvested by certain non-U.S. subsidiaries. Also included in the provision for income taxes in 2005 is an estimated provision of $19.7 million associated with our decision to repatriate approximately $85.8 million in additional dividends above the base and extraordinary dividend amounts, as defined by the Act, from unremitted foreign earnings that were previously considered indefinitely reinvested. Also included in the provision for income taxes in 2005 is a $1.4 million beneficial change in estimate for the expected income tax benefit for previously paid state income taxes, which became recoverable due to a favorable state court decision that became final during 2004, and an estimated $24.1 million reduction in estimated income taxes payable primarily due to the resolution of several significant previously uncertain income tax audit issues, including the resolution of certain transfer pricing issues for which an Advance Pricing Agreement, or APA, was executed with the Internal Revenue Service in the U.S. during the third quarter of 2005. The APA covers tax years 2002 through 2008. The $24.1 million reduction in estimated income taxes payable also includes beneficial changes associated with other transfer price settlements for a discontinued product line, which was not covered by the APA, the deductibility of transaction costs associated with the 2002 spin-off of AMO and intangible asset issues related to certain assets of Allergan Specialty Therapeutics, Inc. and Bardeen Sciences Company, LLC, which we acquired in 2001 and 2003, respectively. This change in estimate relates to tax years currently under examination or not yet settled through expiry of the statute of limitations.
      Excluding the impact of the pre-tax restructuring charges, transition/duplicate operating expenses and gains from the sale of the distribution business in India and the sale of assets used for contract manufacturing, and the related income tax provision (benefit) associated with these pre-tax amounts, the provision for income taxes due to the extraordinary dividends and additional dividends above the base and extraordinary dividend amounts, the decrease in the provision for income taxes resulting from the additional income tax benefit for previously paid state income taxes which became recoverable, and reduction in estimated income taxes payable due to the resolution of several significant uncertain income tax audit issues, our adjusted effective tax rate for 2005 was 27.5%. We believe that the use of an adjusted effective tax rate, which excludes the impact of certain discrete items, provides a more meaningful measure of the impact of income taxes on our results of operations.

      Included in our operating income in 2004 are pre-tax restructuring charges of $7.0 million primarily associated with the scheduled termination of our manufacturing and supply agreement with AMO. We recorded an income tax benefit of $0.8 million related to these pre-tax restructuring charges. Included in our provision for income taxes in 2004 is an estimated $6.1 million income tax benefit for previously paid state income taxes, which became recoverable due to a favorable state court decision that became final during the second quarter of 2004. Excluding the impact of the $7.0 million pre-tax restructuring charges and related tax benefit of $0.8 million, and the $6.1 million income tax benefit from the state court decision, our adjusted effective tax rate for 2004 was 29.8%. Included in our operating loss in 2003 are pre-tax charges of $278.8 million and $179.2 million for in-process research and development associated with our acquisitions of Bardeen and Oculex, respectively. We recorded an income tax benefit of $100.8 million related to the Bardeen charge because the acquisition was considered to be an asset acquisition for tax purposes whereas no income tax benefit was recorded for the Oculex charge because the acquisition was considered to be an acquisition of stock for tax purposes. Excluding the impact of the total $458.0 million of in-process research and development charges and related tax benefit of $100.8 million, our adjusted effective tax rate for 2003 was 28.7%.
      The decrease in the adjusted effective tax rate to 27.5% in 2005 compared to the adjusted effective tax rate in 2004 of 29.8% is primarily due to a tax rate benefit related to an increase in the mix of our earnings generated in non-U.S. jurisdictions with low tax rates in 2005 compared to 2004, a decrease in the valuation allowance related to a change in estimate of the amount of realizable deferred tax assets in Japan stemming from the recent licensing agreement with GlaxoSmithKline and an increase in the expected income tax benefit from utilizing available foreign tax credits, partially offset by a net increase in the estimate for income taxes payable for certain contingent income tax liabilities.

Table of Contents

      The increase in the adjusted effective tax rate to 29.8% in 2004 compared to the adjusted effective tax rate in 2003 of 28.7% was primarily attributable to the fact that our 2003 rate reflected the benefit of reserves for tax audit settlements, which were released in 2003, partially offset by a positive tax rate effect from changes in the mix of our earnings during 2004 compared to 2003.
Net Earnings
      Net earnings in 2005 were $403.9 million compared to net earnings of $377.1 million in 2004. The $26.8 million increase in net earnings was primarily the result of the $43.5 million increase in operating income and a $23.6 million increase in total net non-operating income, partially offset by an increase in the provision for income taxes of $38.4 million.
      Net earnings were $377.1 million in 2004 compared to a net loss of $52.5 million in 2003. The increase of $429.6 million in net earnings was primarily the result of the $551.1 million increase in operating income and a $10.5 million increase in total net non-operating income, partially offset by an increase in the provision for income taxes of $131.8 million.
Liquidity and Capital Resources
      We assess our liquidity by our ability to generate cash to fund our operations. Significant factors in the management of liquidity are: funds generated by operations; levels of accounts receivable, inventories, accounts payable and capital expenditures; the extent of our stock repurchase program; funds required for acquisitions; adequate credit facilities; and financial flexibility to attract long-term capital on satisfactory terms.
      Historically, we have generated cash from operations in excess of working capital requirements. The net cash provided by operating activities was $424.6 million in 2005 compared to $548.5 million in 2004 and $435.3 million in 2003. Cash flow from operating activities decreased in 2005 compared to 2004, primarily as a result of higher income taxes paid, an increase in contributions to our pension plans and an increase in cash required to fund the growth in other current assets, partially offset by an increase in earnings from operations, including the effect of adjusting for non-cash items, and an increase in other liabilities, primarily for deferred income related to an up-front payment received in connection with our licensing arrangement with GlaxoSmithKline. The increase in income taxes paid is primarily due to payments for the estimated U.S. income tax liability for the repatriation of certain foreign earnings and advance payments in anticipation of income tax audit settlements. We paid pension contributions of $49.6 million in 2005 compared to $16.9 million in 2004. The increase in the amount of pension contributions in 2005 compared to 2004 is primarily due to the negative impact of lower discount rates on the calculation of our accumulated benefit obligations as of September 30, 2005, the measurement date for our pension plans, and our desire to maintain plan assets in excess of accumulated benefit obligations in our funded pension plans. In 2006, we expect to pay pension contributions of between approximately $14.0 million and $16.0 million.
      At December 31, 2005, we had consolidated unrecognized net actuarial losses of $178.4 million which were included in our reported net prepaid benefit costs. The unrecognized net actuarial losses resulted primarily from lower than expected investment returns on pension plan assets in 2002 and 2001 and decreases in the discount rates used to measure projected benefit obligations that occurred over the past five years. Assuming constant actuarial assumptions estimated as of our pension plans’ measurement date of September 30, 2005, we expect the amortization of these unrecognized net actuarial losses to increase our total pension costs by approximately $3.4 million in 2006 compared to the amortization of approximately $9.5 million of unrecognized net actuarial losses included in pension costs expensed in 2005. The amortization of unrecognized net actuarial losses included in pension costs in 2004 and 2003 was $6.7 million and $3.1 million, respectively. The future amortization of the unrecognized net actuarial losses is not expected to materially affect future pension contribution requirements.
      Cash flow from operating activities increased in 2004 compared to 2003, primarily as a result of the increase in earnings from operations, including the effect of adjusting for non-cash items, an increase in other accrued expenses, other liabilities and income taxes payable, partially offset by an increase in cash required to

fund trade receivables, principally in North America, and growth in inventories, primarily finished goods for eye care pharmaceuticals and Botox®, and higher income taxes paid. We paid pension contributions of $16.9 million in 2004 compared to $14.7 million in 2003.
      Net cash used in investing activities was $182.1 million in 2005, compared to $106.8 million in 2004 and $594.9 million in 2003. Excluding net cash paid of $469.5 million for the acquisitions of Bardeen and Oculex in 2003, cash used in investing activities in 2003 would have been $125.4 million. We invested $78.5 million in new facilities and equipment during 2005 compared to $96.4 million in 2004 and $109.6 million in 2003. During 2005 and 2004, the additions to property, plant and equipment included costs to construct an expansion of our Botox® manufacturing facilities in Ireland and a new biologics facility in Irvine, California, which we completed in 2005. Capital expenditures during 2005 also included the purchase of approximately four acres of additional real property contiguous to our main facility in Irvine, California. During 2003, the additions to property, plant and equipment included costs to construct a new research and development facility in Irvine, California, which we completed in 2004. Net cash used in investing activities also includes $13.6 million, $10.5 million and $12.3 million to acquire software during 2005, 2004 and 2003, respectively. In 2005, we paid $110.0 million in connection with a royalty buyout agreement relating to Restasis®, our drug for the treatment of chronic dry eye disease, of which $99.3 million was capitalized as an intangible licensing asset, and $10.7 million was used to pay previously accrued net royalty obligations.
      Net cash provided by financing activities was $160.3 million in 2005, composed primarily of a $157.0 million increase in notes payable and $149.9 million of cash provided by the sale of stock to employees, partially offset by $94.3 million of cash used for the purchase of treasury stock and $52.3 million for payment of dividends. On January 31, 2006, our Board of Directors declared a quarterly cash dividend of $0.10 per share, payable on March 14, 2006 to stockholders of record on February 17, 2006. Net cash used in financing activities was $51.9 million in 2004, composed primarily of $65.2 million for purchases of treasury stock, $47.3 million for payment of dividends and $23.0 million for net repayments of debt, partially offset by $83.6 million of cash provided by the sale of stock to employees. Net cash used in financing activities was $116.8 million in 2003, composed primarily of $90.6 million for purchases of treasury stock, $46.9 million for payment of dividends and $46.7 million for repayments of convertible borrowings and long-term debt. Cash was provided by the sale of stock to employees of $47.0 million and an increase in notes payable and commercial paper borrowings of $20.4 million. We maintain an evergreen stock repurchase program. Our evergreen stock repurchase program authorizes us to repurchase our common stock for the primary purpose of funding our stock-based benefit plans. Under the stock repurchase program, we may maintain up to 9.2 million repurchased shares in our treasury account at any one time. As of December 31, 2005, we held approximately 1.4 million treasury shares under this program. We are uncertain as to the level of stock repurchases, if any, to be made in the future.
      In December 2005, we entered into a definitive merger agreement to acquire Inamed Corporation, or Inamed. Under the terms of the agreement, we have made a tender offer to acquire each outstanding common share of Inamed for either $84.00 in cash or 0.8498 of a share of our common stock, at the election of the holder. Elections of Inamed stockholders with respect to the form of consideration they will receive are subject to proration such that we will pay 45% of the aggregate consideration in cash and 55% of the aggregate consideration in shares of our common stock. We expect the cash portion of the purchase price to be approximately $1.4 billion. In order to finance part of the cash portion of the purchase price, we executed a commitment letter pertaining to a $1.1 billion bridge credit facility in December 2005. Subsequent to the closing of the transaction to acquire Inamed, we expect to replace the bridge financing with conventional long-term financing. As of December 31, 2005 there were no borrowings outstanding under the committed bridge credit facility.
      At December 31, 2005, we had a committed long-term credit facility, a committed foreign line of credit in Japan, a commercial paper program, a medium term note program, an unused debt shelf registration statement that we may use for a new medium term note program and other issuances of debt securities, and various foreign bank facilities. The committed long-term credit facility allows for borrowings of up to $400 million through May 2009. The committed foreign line of credit allows for borrowings of up to three billion Japanese yen (approximately $25.5 million) through July 2006. The commercial paper program also

provides for up to $300 million in borrowings. The current medium term note program allows us to issue up to an additional $7.5 million in registered notes on a non-revolving basis. The debt shelf registration statement provides for up to $350 million in additional debt securities. Borrowings under the committed long-term credit facility and medium-term note program are subject to certain financial and operating covenants that include, among other provisions, maintaining minimum debt to capitalization ratios and minimum consolidated net worth. Certain covenants also limit subsidiary debt and restrict dividend payments. We were in compliance with these covenants at December 31, 2005 and had approximately $1.2 billion available for dividends at December 31, 2005. As of December 31, 2005, we had no borrowings under our committed foreign line of credit or commercial paper program, $164.0 million in borrowings under our committed long-term credit facility, $5.6 million in borrowings under various foreign bank loans and $57.5 million in borrowings outstanding under the medium term note program.
      On November 6, 2002, we issued zero coupon convertible senior notes due 2022, or Senior Notes, in a private placement with an aggregate principal amount at maturity of $641.5 million. The Senior Notes, which were issued at a discount of $141.5 million, are unsecured, accrue interest at 1.25% annually and mature on November 6, 2022. The Senior Notes are convertible into 11.41 shares of our common stock for each $1,000 principal amount at maturity if the closing price of our common stock exceeds certain levels, the credit ratings assigned to the Senior Notes are reduced below specified levels, or we call the Senior Notes for redemption, make specified distributions to our stockholders or become a party to certain consolidation, merger or binding share exchange agreements. On July 28, 2004, we, together with Wells Fargo Bank, as trustee, executed a supplemental indenture with respect to the Senior Notes to amend the redemption and conversion provisions to restrict our ability to issue common stock in lieu of cash to holders of the Senior Notes upon any redemption or conversion. Upon any redemption, we are now required to pay the entire redemption amount in cash. In addition, upon any conversion, we will pay cash up to the accreted value of the Senior Notes converted and will have the option to pay any amounts due in excess of the accreted value in either cash or common stock. The rights of the holders of the Senior Notes were not affected or limited by the supplemental indenture. As of December 31, 2005, the conversion criteria were met, and holders may elect to convert the Senior Notes between January 1, 2006 and March 31, 2006. See Note 7, “Convertible Notes,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for a description of the conversion features. Based on the terms of the Senior Notes, an assessment of the conversion criteria is performed each fiscal quarter, the result of which affects the holders’ ability to convert the Senior Notes in the immediately succeeding fiscal quarter. If the conversion criteria are not met in our fiscal quarter ending March 31, 2006, the holders’ ability to convert the Senior Notes will be restricted until the conversion criteria are again met.
      We include the dilutive effect from the assumed conversion of the Senior Notes, if any, in our computation of diluted earnings per share, assuming amounts due in excess of the accreted value will be paid in common stock. As a sensitivity measure, a $5.00 increase in the average price of our common stock would have resulted in an increase of approximately 0.3 million shares of common stock to the total number of diluted shares used to compute diluted earnings per share for the year ended December 31, 2005.
      Holders of the Senior Notes may require us to purchase the Senior Notes on any of the following dates at the following prices: $829.51 per Senior Note on November 6, 2007; $882.84 per Senior Note on November 6, 2012; and $939.60 per Senior Note on November 6, 2017. Pursuant to the supplemental indenture, we are required to pay cash for any Senior Notes purchased by us on any of these three dates. Prior to November 6, 2007 we may redeem all or a portion of Senior Notes for cash in an amount equal to their accreted value only if the price of our common stock reaches certain thresholds for a specified period of time. On or after November 6, 2007, we may redeem all or a portion of the Senior Notes for cash in an amount equal to their accreted value.
      A significant amount of our existing cash and equivalents are held by non-U.S. subsidiaries. We currently plan to use these funds in our operations outside the United States. Withholding and U.S. taxes have not been provided for unremitted earnings of certain non-U.S. subsidiaries because we have reinvested these earnings indefinitely in such operations. As of December 31, 2005 we had approximately $299.5 million in unremitted

53


Table of Contents

earnings outside the United States for which withholding and U.S. taxes were not provided. Tax costs would be incurred if these funds were remitted to the United States.
      During 2005, we repatriated a total of $759.8 million in cash previously held by certain non-U.S. subsidiaries, primarily in connection with the American Jobs Creation Act of 2004. See Note 8, “Income Taxes,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for a discussion of our repatriation of certain unremitted foreign earnings and the estimated income tax costs of such repatriation activities.
      Our manufacturing and supply agreement with AMO terminated as scheduled in June 2005. As of December 31, 2005, we recorded cumulative pre-tax restructuring charges of $21.6 million. We expect to record an additional $2.0 million to $3.0 million in pre-tax restructuring charges during the first three quarters of 2006 to complete the refurbishment of facilities previously used for contract manufacturing.
      We currently estimate that the pre-tax charges resulting from the restructuring or our European operations, including transition and duplicate operating expenses, will be between $46 million and $51 million and capital expenditures will be between $3 million and $4 million. We began to incur these amounts in the first quarter of 2005 and expect to continue to incur them up through and including the second quarter of 2006. Of the total amount of pre-tax charges and capital expenditures, approximately $43 million to $48 million are expected to be cash expenditures. During the year ended December 31, 2005, we recorded pre-tax restructuring charges of $28.9 million and transition/duplicate operating expenses of $5.6 million related to the implementation of this restructuring of our European operations. We expect to complete the additional restructuring activities by the end of the second quarter of 2006.
      We currently estimate that the pre-tax charges resulting from the restructuring of our operations in Japan will be between $3.0 million and $5.0 million, substantially all of which are expected to be cash expenditures. During 2005, we recorded pre-tax restructuring charges of $2.3 million, and we expect to continue to incur additional charges up through and including the second quarter of 2006.
      We believe that the net cash provided by operating activities, supplemented as necessary with borrowings available under our existing credit facilities and existing cash and equivalents, will provide us with sufficient resources to meet our expected obligations under the definitive merger agreement with Inamed, working capital requirements, debt service and other cash needs over the next year.
Inflation
      Although at reduced levels in recent years, inflation continues to apply upward pressure on the cost of goods and services that we use. The competitive and regulatory environments in many markets substantially limit our ability to fully recover these higher costs through increased selling prices. We continually seek to mitigate the adverse effects of inflation through cost containment and improved productivity and manufacturing processes.
Foreign Currency Fluctuations
      Approximately 32.5% of our revenues in 2005 were derived from operations outside the United States, and a portion of our international cost structure is denominated in currencies other than the U.S. dollar. As a result, we are subject to fluctuations in sales and earnings reported in U.S. dollars due to changing currency exchange rates. We routinely monitor our transaction exposure to currency rates and implement certain economic hedging strategies to limit such exposure, as appropriate. The net impact of foreign currency fluctuations on our sales was as follows: a $22.3 million increase in 2005, a $41.9 million increase in 2004, and a $45.9 million increase in 2003. The 2005 sales increase included $1.1 million related to the euro, $5.2 million related to the Canadian dollar, $1.3 million related to the Australian dollar, $10.9 million related to the Brazilian real, $1.2 million related to the Mexican peso and $2.3 million related to other Latin American currencies. The 2004 sales increase included $23.9 million related to the euro, $4.5 million related to the British pound, $4.2 million related to the Canadian dollar, $4.0 million related to the Australian dollar, $2.0 million related to the Japanese yen and $1.8 million related to the Brazilian real. The 2003 sales increase

54


Table of Contents

included increases of $38.7 million related to the euro, $5.4 million related to the Canadian dollar, $4.6 million related to the Australian dollar and $2.1 million related to the Japanese yen, partially offset by decreases of $3.1 million related to the Mexican peso, $1.7 million related to the Brazilian real and $1.5 million related to other Latin American currencies. See Note 1, “Summary of Significant Accounting Policies,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for a description of our accounting policy on foreign currency translation.
Oculex Pharmaceuticals, Inc.
      On November 20, 2003, we purchased all of the outstanding equity interests of Oculex Pharmaceuticals, Inc., or Oculex, a privately owned company, for an aggregate purchase price of approximately $223.8 million, net of cash acquired, including transaction costs of $1.6 million and $6.1 million in other assets related to Oculex. The acquisition was accounted for by the purchase method of accounting and accordingly, the consolidated statements of operations include the results of Oculex beginning November 20, 2003. In conjunction with the acquisition, we recorded a charge to research and development for in-process research and development expense of $179.2 million during 2003 for an acquired in-process research and development asset which we determined was not yet complete and had no alternative future uses in its current state. This asset is Oculex’s lead investigational product, Posurdex®, which is a proprietary, bioerodable, sustained release implant that delivers dexamethasone to the targeted disease site at the back of the eye. We have begun Phase 3 clinical trials for macular edema associated with diabetes and vein occlusions. Additionally, we determined that the assets acquired also included a proprietary technology drug delivery platform which had alternative future uses in its current state, which we separately valued and capitalized as core technology. The core technology is a versatile bioerodable polymer drug delivery technology which can be used for sustained local delivery of compounds to the eye. See Note 3, “Acquisitions,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for a discussion of the acquisition of Oculex.
      We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions. A summary of the net assets acquired follows:
         
    (in millions)
Current assets
  $ 0.6  
Property, plant and equipment
    1.0  
Capitalized intangible core technology (straight-line amortization over a 15 year useful life)
    29.6  
In-process research and development
    179.2  
Other non-current assets, primarily deferred tax assets
    19.3  
Accounts payable and accrued liabilities
    (5.9 )
         
    $ 223.8  
         
      During 2004, we adjusted the fair value of certain net assets acquired by $0.6 million, which resulted in a decrease in the amount of capitalized core technology and in-process research and development of $0.1 million and $0.5 million, respectively. The $0.5 million decrease in in-process research and development was included in research and development expenses in 2004.
Bardeen Sciences Company, LLC
      On May 16, 2003, we completed an acquisition of all of the outstanding equity interests of Bardeen Sciences Company, LLC, or Bardeen, from Farallon Pharma Investors, LLC, or Farallon, for an aggregate purchase price of approximately $264.6 million, including transaction costs of $1.1 million and $12.8 million in certain intangible contract-based product marketing and other rights, net of cash acquired. We acquired all of Bardeen’s assets, which consisted of the rights to certain pharmaceutical compounds under development and research projects, including memantine, androgen tears, tazarotene in oral form for the treatment of acne, AGN 195795, AGN 196923, AGN 197075, a hypotensive lipid/timolol combination, a photodynamic therapy

Table of Contents

project, tyrosine kinase inhibitors for the treatment of ocular neovascularization, a vision-sparing project and a retinal disease project.
      Bardeen was formed in April 2001 upon our contribution of a portfolio of pharmaceutical compounds and research projects and the commitment of a $250 million capital investment by Farallon. In return for our contribution of the portfolio, we received certain commercialization rights to market products developed from the compounds comprising the portfolio. In addition, we acquired an option to purchase rights to any one product and a separate option to purchase all of the outstanding equity interests of Bardeen at an option price based on the amount of research and development funds expended by Bardeen on the portfolio and the time elapsed since the effective date of the option agreement. We acquired Bardeen upon the exercise of our option to purchase all the outstanding equity interests of Bardeen at the option price. Neither we nor any of our officers or directors owned any interest in Bardeen or Farallon prior to the acquisition of the outstanding interests.
      We determined that the assets acquired consisted entirely of incomplete in-process research and development assets and that these assets had no alternative future uses in their current state.
      The estimated fair value of assets acquired and liabilities assumed are as follows:
         
    (in millions)
Intangible assets — In-process research and development
  $ 278.8  
Accounts payable
    (14.2 )
         
    $ 264.6  
         
      From the time of Bardeen’s formation until the acquisition date, we performed research and development on the compounds comprising the portfolio on Bardeen’s behalf pursuant to a research and development services agreement between us and Bardeen under which all such activities were fully funded by Bardeen and services were performed on a cost plus 10% basis. Because the financial risk associated with the research and development was transferred to Bardeen, we recognized revenues and related costs as services were performed under such agreements as required under SFAS No. 68, Research and Development Arrangements. These amounts are included in research service revenues in the accompanying consolidated statements of operations. For the year ended December 31, 2003, we recognized $16.0 million in research revenues and $14.5 million in research costs under the research and development services agreement with Bardeen.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
      In the normal course of business, our operations are exposed to risks associated with fluctuations in foreign currency exchange rates. We address these risks through controlled risk management that includes the use of derivative financial instruments to economically hedge or reduce these exposures. We do not enter into financial instruments for trading or speculative purposes. See Note 11, “Financial Instruments,” in the notes to the consolidated financial statements listed under Item 15(a) of Part IV of this report for activities relating to foreign currency risk management.
      To ensure the adequacy and effectiveness of our foreign exchange hedge positions, we continually monitor our foreign exchange forward and option positions both on a stand-alone basis and in conjunction with our underlying foreign currency exposures, from an accounting and economic perspective.
      However, given the inherent limitations of forecasting and the anticipatory nature of the exposures intended to be hedged, we cannot assure you that such programs will offset more than a portion of the adverse financial impact resulting from unfavorable movements in foreign exchange rates. In addition, the timing of the accounting for recognition of gains and losses related to mark-to-market instruments for any given period may not coincide with the timing of gains and losses related to the underlying economic exposures and, therefore, may adversely affect our consolidated operating results and financial position.
      We record current changes in the fair value of open foreign currency option contracts as “Unrealized gain (loss) on derivative instruments, net,” and we record the gains and losses realized from settled option

56


Table of Contents

contracts in “Other, net” in the accompanying consolidated statements of operations. The premium costs of purchased foreign exchange option contracts are recorded in “Other current assets” and are amortized to “Other, net” over the life of the options. We have recorded all unrealized and realized gains and losses from foreign currency forward contracts through “Other, net” in the accompanying consolidated statements of operations.
Interest Rate Risk
      Our interest income and expense is more sensitive to fluctuations in the general level of U.S. interest rates than to changes in rates in other markets. Changes in U.S. interest rates affect the interest earned on our cash and equivalents, interest expense on our debt as well as costs associated with foreign currency contracts.
      At December 31, 2005, we had approximately $169.6 million of variable rate debt. If the interest rates on the variable rate debt were to increase or decrease by 1% for the year, annual interest expense would increase or decrease by approximately $1.7 million.
      The tables below present information about certain of our investment portfolio and our debt obligations at December 31, 2005 and 2004:

Guarantees
      Our Certificate of Incorporation, as amended, provides that we will indemnify, to the fullest extent permitted by the Delaware General Corporation Law, each person that is involved in or is, or is threatened to be, made a party to any action, suit or proceeding by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of Allergan or was serving at our request as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise. We have also entered into contractual indemnity agreements with each of our directors and certain

58


Table of Contents

officers pursuant to which we have agreed to indemnify such directors and officers against any payments they are required to make as a result of a claim brought against such officer or director in such capacity, excluding claims (i) relating to the action or inaction of a director or officer that resulted in such director or officer gaining personal profit or advantage, (ii) for an accounting of profits made from the purchase or sale of our securities within the meaning of Section 16(b) of the Securities Exchange Act of 1934 or similar provisions of any state law or (iii) that are based upon or arise out of such director’s or officer’s knowingly fraudulent, deliberately dishonest or willful misconduct. The maximum potential amount of future payments that we could be required to make under these indemnification provisions is unlimited. However, we have purchased directors’ and officers’ liability insurance policies intended to reduce our monetary exposure and to enable us to recover a portion of any future amounts paid. We have not previously paid any material amounts to defend lawsuits or settle claims as a result of these indemnification provisions. As a result, we believe the estimated fair value of these indemnification arrangements is minimal.
      We customarily agree in the ordinary course of our business to indemnification provisions in agreements with clinical trials investigators in our drug development programs, in sponsored research agreements with academic and not-for-profit institutions, in various comparable agreements involving parties performing services for us in the ordinary course of business, and in our real estate leases. We also customarily agree to certain indemnification provisions in our drug discovery and development collaboration agreements. With respect to our clinical trials and sponsored research agreements, these indemnification provisions typically apply to any claim asserted against the investigator or the investigator’s institution relating to personal injury or property damage, violations of law or certain breaches of our contractual obligations arising out of the research or clinical testing of our compounds or drug candidates. With respect to lease agreements, the indemnification provisions typically apply to claims asserted against the landlord relating to personal injury or property damage caused by us, to violations of law by us or to certain breaches of our contractual obligations. The indemnification provisions appearing in our collaboration agreements are similar, but in addition provide some limited indemnification for the collaborator in the event of third party claims alleging infringement of intellectual property rights. In each of the above cases, the term of these indemnification provisions generally survives the termination of the agreement. The maximum potential amount of future payments that we could be required to make under these provisions is generally unlimited. We have purchased insurance policies covering personal injury, property damage and general liability intended to reduce our exposure for indemnification and to enable us to recover a portion of any future amounts paid. We have not previously paid any material amounts to defend lawsuits or settle claims as a result of these indemnification provisions. As a result, we believe the estimated fair value of these indemnification arrangements is minimal.
Foreign Currency Risk
      Overall, we are a net recipient of currencies other than the U.S. dollar and, as such, benefit from a weaker dollar and are adversely affected by a stronger dollar relative to major currencies worldwide. Accordingly, changes in exchange rates, and in particular a strengthening of the U.S. dollar, may negatively affect our consolidated sales, gross margins or operating expenses as expressed in U.S. dollars.
      From time to time, we enter into foreign currency option and forward contracts to reduce earnings and cash flow volatility associated with foreign exchange rate changes to allow management to focus its attention on our core business issues and challenges. Accordingly, we enter into contracts which change in value as foreign exchange rates change to economically offset the effect of changes in value of foreign currency assets and liabilities, commitments and anticipated foreign currency denominated sales and operating expenses. We enter into foreign currency forward and option contracts in amounts between minimum and maximum anticipated foreign exchange exposures, generally for periods not to exceed one year.
      We use foreign currency option contracts, which provide for the sale or purchase of foreign currencies to offset foreign currency exposures expected to arise in the normal course of our business. While these instruments are subject to fluctuations in value, such fluctuations are anticipated to offset changes in the value of the underlying exposures. The principal currencies subject to this process are the Canadian dollar, Mexican peso, Australian dollar, Brazilian real, euro, Japanese yen and the U.K. Pound.

      All of our outstanding foreign exchange forward contracts are entered into to protect the value of intercompany receivables denominated in currencies other than the lender’s functional currency. The realized and unrealized gains and losses from foreign currency forward contracts and revaluation of the foreign denominated intercompany receivables are recorded through “Other, net” in the accompanying consolidated statements of operations.
      All of our outstanding foreign currency options are entered into to reduce the volatility of earnings generated in currencies other than the U.S. dollar, primarily earnings denominated in the Canadian dollar, Mexican peso, Australian dollar, Brazilian real, euro, Japanese yen and the U.K. Pound. Current changes in the fair value of open foreign currency option contracts are recorded through earnings as “Unrealized gain (loss) on derivative instruments, net” while any realized gains (losses) on settled contracts are recorded through earnings as “Other, net” in the accompanying consolidated statements of operations. The premium costs of purchased foreign exchange option contracts are recorded in “Other current assets” and amortized to “Other, net” over the life of the options.

Recently Adopted Accounting Standards
      In March 2005, the Financial Accounting Standards Board (FASB) issued Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations (FIN 47). FIN 47 clarifies that conditional obligations meet the definition of an asset retirement obligation in SFAS No. 143, Accounting for Asset Retirement Obligations, and therefore should be recognized if their fair value is reasonably estimable. We adopted the provisions of FIN 47 in our fourth fiscal quarter of 2005. The adoption did not have a material effect on our consolidated financial statements.
      In December 2004, Financial Accounting Standards Board Position 109-2 (FASB Staff Position 109-2) was issued and was effective upon issuance. FASB Staff Position 109-2 establishes standards for how an issuer accounts for a special one-time dividends received deduction on the repatriation of certain foreign earnings to a U.S. taxpayer pursuant to the American Jobs Creation Act of 2004 (the Act). The Financial Accounting Standards Board (FASB) staff believes that the lack of clarification of certain provisions within the Act and the timing of the enactment necessitate a practical exception to the Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No. 109), requirement to reflect in the period of enactment the effect of a new tax law. Accordingly, an enterprise is allowed time beyond the financial reporting period of enactment to evaluate the effect of the Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. We determined during our second fiscal quarter 2005 that we had sufficient information to make an informed decision on the impact of the Act on our repatriation plans and recorded a $32.8 million tax liability based on a plan to repatriate approximately $674.0 million in extraordinary dividends as defined by the Act. Upon the subsequent execution of the divided repatriation plan in 2005, we repatriated $674.0 million in extraordinary dividends and adjusted our estimate of the tax liability on the extraordinary dividends to $29.9 million.
      In December 2004, Financial Accounting Standards Board Position 109-1 (FASB Staff Position 109-1) was issued and was effective upon issuance. FASB Staff Position 109-1 requires us to treat the effect of a newly enacted U.S. tax deduction, beginning in 2005, for income attributable to United States production activities as a special deduction, and not a tax rate reduction, in accordance with SFAS No. 109. We adopted the provisions of FASB Staff Position 109-1 in our first fiscal quarter of 2005. The adoption did not have a material effect on our consolidated financial statements.
      In October 2004, the FASB ratified the consensuses reached by the Emerging Issues Task Force (EITF) in EITF Issue No. 04-8, The Effect of Contingently Convertible Instruments on Diluted Earnings per Share (EITF 04-8), which became effective for reporting periods ending after December 15, 2004. EITF No. 04-8 requires all instruments that have embedded conversion features, including contingently convertible debt, that are contingent on market conditions indexed to an issuer’s share price to be included in diluted earnings per share computations, if dilutive, regardless of whether the market conditions have been met. We adopted the provisions of EITF No. 04-8 in our fourth fiscal quarter of 2004 and restated all prior period diluted earnings per share amounts to conform to the guidance in EITF No. 04-8.
New Accounting Standards Not Yet Adopted
      In May 2005, the FASB issued Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections (SFAS No. 154). SFAS No. 154 requires retrospective application to prior-period financial statements of changes in accounting principles, unless a new accounting pronouncement provides specific transition provisions to the contrary or it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also redefines “restatement” as the revising of previously issued financial statements to reflect the correction of an error. This statement is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005.
      In December 2004, Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), was issued and is effective for entities that do not file as small business issuers as of the beginning of the first interim reporting period of fiscal years that begin after June 15, 2005, which is our first fiscal quarter of 2006. SFAS No. 123R requires companies to recognize in the income statement the

61


Table of Contents

grant-date fair value of stock options and other equity-based compensation issued to employees. SFAS No. 123R sets accounting requirements for measuring, recognizing and reporting share-based compensation, including income tax considerations. Upon adoption of SFAS No. 123R, we will begin recognizing the cost of stock options using the modified prospective application method whereby the cost of new awards and awards modified, repurchased or cancelled after the required effective date and the portion of awards for which the requisite service has not been rendered (unvested awards) that are outstanding as of the required effective date shall be recognized as the requisite service is rendered on or after the required effective date. Because we historically accounted for share-based payment arrangements under the intrinsic value method of accounting, we will continue to provide the disclosures required by Statement of Financial Accounting Standards No. 123 until the effective date of SFAS No. 123R, regarding pro forma net earnings and basic and diluted earnings per share, had compensation expense for our stock options been recognized based upon the fair value for awards granted. We will adopt the provisions of SFAS No. 123R in our first fiscal quarter of 2006. For fiscal year 2006, we estimate the incremental increase to compensation costs related to the expensing of stock options will be approximately $28.0 million, net of tax.
Item 8. Financial Statements and Supplementary Data

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
      None.
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
      We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Principal Executive Officer and our Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Our management, including our Principal Executive Officer and our Principal Financial Officer, does not expect that our disclosure controls or procedures will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Allergan have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Also, we have investments in certain unconsolidated entities. As we do not control or manage these entities, our disclosure controls and procedures with respect to such entities are necessarily substantially more limited than those we maintain with respect to our consolidated subsidiaries.
      We carried out an evaluation, under the supervision and with the participation of our management, including our Principal Executive Officer and our Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2005, the end of the annual period covered by this report. The evaluation of our disclosure controls and procedures included a review of the disclosure controls’ and procedures’ objectives, design, implementation and the effect of the controls and procedures on the information generated for use in this report. In the course of our evaluation, we sought to

62


Table of Contents

identify data errors, control problems or acts of fraud and to confirm the appropriate corrective actions, including process improvements, were being undertaken.
      Based on the foregoing, our Principal Executive Officer and our Principal Financial Officer concluded that, as of the period covered by this report, our disclosure controls and procedures were effective and were operating at the reasonable assurance level.
      Further, management determined that, as of December 31, 2005, there were no changes in our internal control over financial reporting that occurred during the fourth fiscal quarter that have materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
      Our management report on internal control over financial reporting and the attestation report on management’s assessment of our internal control over financial reporting are contained in Item 15(a)(1) of Part IV of this report.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
      Internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, refers to the process designed by, or under the supervision of, our Principal Executive Officer and Principal Financial Officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:
        (1) Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of Allergan;
 
        (2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of Allergan are being made only in accordance with authorizations of management and directors of Allergan; and
 
        (3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Allergan’s assets that could have a material effect on the financial statements.
      Management’s assessment of the effectiveness of Allergan’s internal control over financial reporting has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report on management’s assessment and on the effectiveness of Allergan’s internal control over financial reporting as of December 31, 2005. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Management is responsible for establishing and maintaining adequate internal control over financial reporting for Allergan.
      Management has used the framework set forth in the report entitled “Internal Control — Integrated Framework” published by the Committee of Sponsoring Organizations of the Treadway Commission to evaluate the effectiveness of Allergan’s internal control over financial reporting. Management has concluded that Allergan’s internal control over financial reporting was effective as of the end of the most recent fiscal year, based on those criteria.

Report of Independent Registered Public Accounting Firm
The Board of Directors and Stockholders of Allergan, Inc.
      We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control over Financial Reporting, that Allergan, Inc. (the “Company”) maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Allergan, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.
      We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
      A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
      Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
      In our opinion, management’s assessment that Allergan, Inc. maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Allergan, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria.
      We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Allergan, Inc. as of December 31, 2005, and the related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended and our report dated March 2, 2006 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm
The Board of Directors and Stockholders of Allergan, Inc.
      We have audited the consolidated balance sheet of Allergan, Inc. (the “Company”) as of December 31, 2005, and the related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended. Our audit also included the financial statement schedule listed in the Index at Item 15(a)2. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audit. The consolidated financial statements and financial statement schedule of the Company at December 31, 2004 and for the years ended December 31, 2004 and 2003, were audited by other auditors whose report dated March 4, 2005, expressed an unqualified opinion on those statements and schedule and included an explanatory paragraph that disclosed the adoption of Emerging Issues Task Force No. 04-08, The Effect of Contingently Convertible Instruments on Diluted Earning Per Share, in the fiscal fourth quarter of 2004 discussed in Note 1 to these financial statements.
      We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether 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 audit provides a reasonable basis for our opinion.
      In our opinion, the 2005 consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Allergan, Inc. at December 31, 2005, and the consolidated results of its operations and its cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule for the year ended December 31, 2005, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
      We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 2, 2006 expressed an unqualified opinion thereon.

ALLERGAN, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1: Summary of Significant Accounting Policies
      The consolidated financial statements include the accounts of Allergan, Inc. (“Allergan” or the “Company”) and all of its subsidiaries. All significant transactions among the consolidated entities have been eliminated from the financial statements.
Use of Estimates
      The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and, as such, include amounts based on informed estimates and judgments of management. Actual results could differ from those estimates.
Foreign Currency Translation
      The financial position and results of operations of the Company’s foreign subsidiaries are generally determined using local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each year-end. Income statement accounts are translated at the average rate of exchange prevailing during the year. Adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ equity. Gains and losses resulting from foreign currency transactions are included in earnings and have not been material in any year presented. (See Note 11, Financial Instruments.)
Cash and Equivalents
      The Company considers cash in banks, repurchase agreements, commercial paper and deposits with financial institutions with maturities of three months or less and that can be liquidated without prior notice or penalty, to be cash and equivalents.
Investments
      The Company has both marketable and non-marketable equity investments in conjunction with its various collaboration arrangements. The Company classifies its marketable equity investments as available-for-sale securities with net unrealized gains or losses recorded as a component of accumulated other comprehensive loss. The non-marketable equity investments represent investments in start-up technology companies or partnerships that invest in start-up technology companies and are recorded at cost. Marketable and non-marketable equity investments are evaluated periodically for impairment. If it is determined that a decline of any investment is other than temporary, then the investment basis would be written down to fair value and the write-down would be included in earnings as a loss.
Inventories
      Inventories are valued at the lower of cost or market (net realizable value). Cost is determined by the first-in, first-out method.
Long-Lived Assets
      Property, plant and equipment are stated at cost. Additions, major renewals and improvements are capitalized, while maintenance and repairs are expensed. Upon disposition, the net book value of assets is relieved and resulting gains or losses are reflected in earnings. For financial reporting purposes, depreciation is generally provided on the straight-line method over the useful life of the related asset. The useful lives for buildings, including building improvements, range from seven years to 40 years and, for machinery and equipment, three years to 15 years. Leasehold improvements are amortized over the shorter of their economic lives or lease terms. Accelerated depreciation methods are generally used for income tax purposes.

ALLERGAN, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
      All long-lived assets are reviewed for impairment in value when changes in circumstances dictate, based upon undiscounted future operating cash flows, and appropriate losses are recognized and reflected in current earnings, to the extent the carrying amount of an asset exceeds its estimated fair value determined by the use of appraisals, discounted cash flow analyses or comparable fair values of similar assets.
Goodwill and Intangible Assets
      Goodwill represents the excess of acquisition cost over the fair value of the net assets of acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead tested for impairment annually. Intangible assets include licensing agreements, trademarks, core technology and other rights, which are being amortized over their estimated useful lives ranging from four to 15 years, and a foreign business license with an indefinite useful life that is not amortized, but instead tested for impairment annually.
Treasury Stock
      Treasury stock is accounted for by the cost method. The Company maintains an evergreen stock repurchase program. The evergreen stock repurchase program authorizes management to repurchase the Company’s common stock for the primary purpose of funding its stock-based benefit plans. Under the stock repurchase program, the Company may maintain up to 9.2 million repurchased shares in its treasury account at any one time. As of December 31, 2005 and 2004, the Company held approximately 1.4 million and 2.8 million treasury shares, respectively, under this program.
Revenue Recognition
      The Company recognizes revenue from product sales when goods are shipped and title and risk of loss transfer to the customer. The Company generally offers cash discounts to customers for the early payment of receivables. Those discounts are recorded as a reduction of revenue and accounts receivable in the same period that the related sale is recorded. The amounts reserved for cash discounts were $1.8 million and $1.3 million at December 31, 2005 and 2004, respectively. The Company permits returns of product from any product line by any class of customer if such product is returned in a timely manner, in good condition and from the normal distribution channels. Return policies in certain international markets provide for more stringent guidelines in accordance with the terms of contractual agreements with customers. Allowances for returns are provided for based upon the Company’s historical patterns of returns matched against the sales from which they originated, and management’s evaluation of specific factors that increase the risk of returns. The amount of allowances for sales returns accrued at December 31, 2005 and 2004 were $5.1 million and $5.8 million, respectively. Historical allowances for cash discounts and product returns have been within the amounts reserved or accrued, respectively.
      Additionally, the Company participates in various managed care sales rebate and other incentive programs, the largest of which relates to Medicaid. Sales rebate and other incentive programs also include chargebacks, which are contractual discounts given primarily to federal government agencies, health maintenance organizations, pharmacy benefits managers and group purchasing organizations. Sales rebates and incentive accruals reduce revenue in the same period that the related sale is recorded and are included in “Other accrued expenses” in the Company’s consolidated balance sheets. The amounts accrued for sales rebates and other incentive programs at December 31, 2005 and 2004 were $71.9 million and $61.4 million, respectively. The Company’s procedures for estimating amounts accrued for sales rebates and other incentive programs at the end of any period are based on available quantitative data and are supplemented by management’s judgment with respect to many factors including, but not limited to, current market place dynamics, changes in contract terms, changes in sales trends, an evaluation of current laws and regulations and product pricing. Quantitatively, the Company uses historical sales, product utilization and rebate data and applies forecasting techniques in order to estimate the Company’s liability amounts. Qualitatively, manage-

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
ment’s judgment is applied to these items to modify, if appropriate, the estimated liability amounts. Additionally, there is a significant time lag between the date the Company determines the estimated liability and when the Company actually pays the liability. Due to this time lag, the Company records adjustments to its estimated liabilities over several periods, which can result in a net increase to earnings or a net decrease to earnings in those periods. Material differences may result in the amount of revenue the Company recognizes from the product sales if the actual amount of rebates and incentives differs materially from the amounts estimated by management.
      Research service revenue is recognized and related costs are recorded as services are performed under research service agreements. At such time, the research service customers are obligated to pay, and such obligation is not refundable.
      The Company recognizes license fees as other income based on the facts and circumstances of each licensing agreement. In general, the Company recognizes income upon the signing of a license agreement that grants rights to products or technology to a third party if the Company has no further obligation to provide products or services to the third party after granting the license. The Company defers income under license agreements when it has further obligations that indicate that a separate earnings process has not culminated.
      Stock-Based Compensation
      As allowed by Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, the Company has elected to continue to apply the intrinsic-value-based method of accounting. Under this method, the Company measures stock-based compensation for option grants to employees assuming that options granted at market price at the date of grant have no intrinsic value. The Company’s contributions of common stock related to the Company’s savings and investment plans are measured at market price at the date of contribution. Restricted stock awards, including restricted stock units, are valued based on the market price of a share of nonrestricted stock on the grant date. No compensation expense has been recognized for stock-based incentive compensation plans other than for the contributions of common stock to the Company’s savings and investment plans and the restricted stock awards under both the incentive compensation plan and the non-employee director equity incentive plan. (See Note 10, Employee Stock Plans.) Had compensation expense for the Company’s stock options under the incentive compensation plan and the non-employee director equity incentive plan been recognized based upon the fair value of awards granted, the Company’s net earnings (loss) would have been reduced (increased) to the following pro forma amounts:
                             
    2005   2004   2003

See New Accounting Standards Not Yet Adopted below for a discussion of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R).
      Acceleration of Vesting of Premium Priced Stock Options
      On July 30, 2001, the Company granted non-qualified stock options to purchase up to 2,500,000 shares of its common stock to participants, including the Company’s executive officers, under the Allergan, Inc. 2001 Premium Priced Stock Option Plan. Each option was issued with three tranches:
  •  The first tranche has an exercise price equal to $88.55;
  •  The second tranche has an exercise price equal to $106.26; and
  •  The third tranche has an exercise price equal to $127.51.
      The 2001 Premium Priced Stock Option Plan provided that each tranche of an option would vest and become exercisable upon the earlier of (i) the date on which the fair value of a share of the Company’s common stock equals or exceeds the applicable exercise price or (ii) five years from the grant date (July 30, 2006). The options expire six years from the grant date (July 30, 2007). The first tranche of the options vested and became exercisable on March 1, 2004 as a result of the fair value of the Company’s common stock exceeding $88.55.
      In response to SFAS No. 123R, on April 25, 2005, the Organization and Compensation Committee of the Company’s Board of Directors approved an acceleration of the vesting of the options issued under the Allergan, Inc. 2001 Premium Priced Stock Option Plan that are held by the Company’s current employees, including the Company’s executive officers, and certain former employees of the Company who received grants while employees prior to the June 2002 spin-off of Advanced Medical Optics, Inc. (AMO). The former employees of the Company are current employees of AMO. As a result of the acceleration, the second tranche and third tranche of each option became immediately vested and exercisable effective as of May 10, 2005. Unlike typical stock options that vest over a predetermined period, the options automatically vest as soon as they are in the money. Consequently, as soon as the options have any value to the participant, they vest according to their terms. Therefore, early vesting does not provide any immediate benefit to participants, including the Company’s executive officers.
      The acceleration of the options eliminated future compensation expense that the Company would otherwise recognize in its income statement with respect to the vesting of such options following the effectiveness of SFAS No. 123R. The future expense that was eliminated is approximately $1.0 million, net of tax (of which approximately $0.1 million, net of tax, is attributable to options held by executive officers). This amount was reflected in the Company’s pro forma footnote disclosure under “Stock-Based Compensation” for the year ended December 31, 2005. This treatment is permitted under the transition guidance provided by SFAS No. 123R.
      Advertising Expenses
      Advertising expenses relating to production costs are expensed as incurred and the costs of television time, radio time and space in publications are expensed when the related advertising occurs. Advertising expenses were approximately $100.5 million, $54.0 million and $45.9 million in 2005, 2004 and 2003, respectively.
      Income Taxes
      The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities, along with net operating loss and credit carryforwards. The Company records a valuation allowance against its deferred tax assets to reduce

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
the net carrying value to an amount that it believes is more likely than not to be realized. When the Company establishes or reduces the valuation allowance against its deferred tax assets, its income tax expense will increase or decrease, respectively, in the period such determination is made.
      Valuation allowances against the Company’s deferred tax assets were $44.1 million and $51.9 million at December 31, 2005 and 2004, respectively. Material differences in the estimated amount of valuation allowances may result in an increase or decrease in the provision for income taxes if the actual amounts for valuation allowances required against deferred tax assets differ from the amounts estimated by management.
      The Company has not provided for withholding and U.S. taxes for the unremitted earnings of certain non-U.S. subsidiaries because the Company has currently reinvested these earnings indefinitely in such operations. At December 31, 2005, the Company had approximately $299.5 million in unremitted earnings outside the United States for which withholding and U.S. taxes were not provided. Tax expense would be incurred if these funds were remitted to the United States. It is not practicable to estimate the amount of the deferred tax liability on such unremitted earnings. Upon remittance, certain foreign countries impose withholding taxes that are then available, subject to certain limitations, for use as credits against the Company’s U.S. tax liability, if any.
      Purchase Price Allocation
      The allocation of purchase price for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed based on their respective fair values. Additionally, the Company must determine whether an acquired entity is considered to be a business or a set of net assets, because a portion of the purchase price can only be allocated to goodwill in a business combination.
      During 2003, the Company acquired Oculex Pharmaceuticals, Inc. (Oculex) and Bardeen Sciences Company, LLC (Bardeen) for aggregate purchase prices of approximately $223.8 million and $264.6 million, respectively. The prices were allocated to identified assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates. The Oculex transaction was determined to be a business combination, while the Bardeen transaction was considered to be an asset acquisition and not a business combination.
      The Company determined that the assets acquired from Oculex and Bardeen consisted principally of incomplete in-process research and development and that these projects had no alternative future uses in their current state. The Company reached this conclusion based on discussions with its business development and research and development personnel, its review of long-range product plans and its review of a valuation report prepared by an independent valuation specialist. The valuation specialist’s report reached a conclusion with regard to the fair value of the in-process research and development assets in a manner consistent with principles prescribed in the AICPA practice aid, Assets Acquired in a Business Combination to Be Used in Research and Development Activities: A Focus on Software, Electronic Devices and Pharmaceutical Industries. In connection with the acquisition of Oculex, the Company determined that the assets acquired also included a proprietary technology drug delivery platform which was separately valued and capitalized as core technology. The Company reached this conclusion based on its determination that the acquired technology had alternative future uses in its current state. The Company believes the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions.
      Comprehensive Income (Loss)
      Comprehensive income (loss) encompasses all changes in equity other than those with stockholders and consists of net earnings (losses), foreign currency translation adjustments, minimum pension liability adjustments and unrealized gains or losses on marketable equity investments. The Company does not provide

for U.S. income taxes on foreign currency translation adjustments since it does not provide for such taxes on undistributed earnings of foreign subsidiaries.
      Reclassifications
      Certain reclassifications of prior year amounts have been made to conform with the current year presentation.
      Recently Adopted Accounting Standards
      In March 2005, the Financial Accounting Standards Board (FASB) issued Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations (FIN 47). FIN 47 clarifies that conditional obligations meet the definition of an asset retirement obligation in SFAS No. 143, Accounting for Asset Retirement Obligations, and therefore should be recognized if their fair value is reasonably estimable. The Company adopted the provisions of FIN 47 in its fourth fiscal quarter of 2005. The adoption did not have a material effect on the Company’s consolidated financial statements.
      In December 2004, Financial Accounting Standards Board Position 109-2 (FASB Staff Position 109-2) was issued and was effective upon issuance. FASB Staff Position 109-2 establishes standards for how an issuer accounts for a special one-time dividends received deduction on the repatriation of certain foreign earnings to a U.S. taxpayer pursuant to the American Jobs Creation Act of 2004 (the Act). The Financial Accounting Standards Board (FASB) staff believes that the lack of clarification of certain provisions within the Act and the timing of the enactment necessitate a practical exception to the Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No. 109), requirement to reflect in the period of enactment the effect of a new tax law. Accordingly, an enterprise is allowed time beyond the financial reporting period of enactment to evaluate the effect of the Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. The Company determined during its second fiscal quarter 2005 that it had sufficient information to make an informed decision on the impact of the Act on the Company’s repatriation plans and recorded a $32.8 million tax liability based on a plan to repatriate approximately $674.0 million in extraordinary dividends as defined by the Act. Upon the subsequent execution of the divided repatriation plan in 2005, the Company repatriated $674.0 million in extraordinary dividends and adjusted its estimate of the tax liability on the extraordinary dividends to $29.9 million.
      In December 2004, Financial Accounting Standards Board Position 109-1 (FASB Staff Position 109-1) was issued and was effective upon issuance. FASB Staff Position 109-1 requires the Company to treat the effect of a newly enacted U.S. tax deduction, beginning in 2005, for income attributable to United States production activities as a special deduction, and not a tax rate reduction, in accordance with SFAS No. 109. The Company adopted the provisions of FASB Staff Position 109-1 in its first fiscal quarter of 2005. The adoption did not have a material effect on the Company’s consolidated financial statements.
      In October 2004, the FASB ratified the consensuses reached by the Emerging Issues Task Force (EITF) in EITF Issue No. 04-8, The Effect of Contingently Convertible Instruments on Diluted Earnings per Share (EITF 04-8), which became effective for reporting periods ending after December 15, 2004. EITF No. 04-8 requires all instruments that have embedded conversion features, including contingently convertible debt, that are contingent on market conditions indexed to an issuer’s share price to be included in diluted earnings per share computations, if dilutive, regardless of whether the market conditions have been met. The Company adopted the provisions of EITF No. 04-8 in its fourth fiscal quarter of 2004 and restated all prior period diluted earnings per share amounts to conform to the guidance in EITF No. 04-8.

      New Accounting Standards Not Yet Adopted
      In May 2005, the FASB issued Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections (SFAS No. 154). SFAS No. 154 requires retrospective application to prior-period financial statements of changes in accounting principles, unless a new accounting pronouncement provides specific transition provisions to the contrary or it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also redefines “restatement” as the revising of previously issued financial statements to reflect the correction of an error. This statement is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005.
      In December 2004, Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), was issued and is effective for entities that do not file as small business issuers as of the beginning of the first interim reporting period of fiscal years that begin after June 15, 2005, which is the Company’s first fiscal quarter of 2006. SFAS No. 123R requires companies to recognize in the income statement the grant-date fair value of stock options and other equity-based compensation issued to employees. SFAS No. 123R sets accounting requirements for measuring, recognizing and reporting share-based compensation, including income tax considerations. Upon adoption of SFAS No. 123R, the Company will begin recognizing the cost of stock options using the modified prospective application method whereby the cost of new awards and awards modified, repurchased or cancelled after the required effective date and the portion of awards for which the requisite service has not been rendered (unvested awards) that are outstanding as of the required effective date shall be recognized as the requisite service is rendered on or after the required effective date. Because the Company historically accounted for share-based payment arrangements under the intrinsic value method of accounting, the Company will continue to provide the disclosures required by Statement of Financial Accounting Standards No. 123 until the effective date of SFAS No. 123R, regarding pro forma net earnings and basic and diluted earnings per share, had compensation expense for the Company’s stock options been recognized based upon the fair value for awards granted. The Company will adopt the provisions of SFAS No. 123R in its first fiscal quarter of 2006. For fiscal year 2006, the Company estimates the incremental increase to compensation costs related to the expensing of stock options will be approximately $28.0 million, net of tax.
Note 2: Restructuring Charges and Transition/ Duplicate Operating Expenses
Restructuring and Streamlining of Operations in Japan
      On September 30, 2005 the Company entered into a long-term agreement with GlaxoSmithKline (GSK) to develop and promote the Company’s Botox® in Japan and China. Under the terms of this agreement, the Company licensed to GSK all clinical development and commercial rights to Botox® in Japan and China. As a result of entering into this agreement, the Company initiated a plan in October 2005 to restructure and streamline operations in Japan. The restructuring seeks to optimize the efficiencies of a third party license and distribution business model and align the Company’s operations in Japan with its reduced role in research and development and commercialization activities under the agreement with GSK.
      The Company has incurred, and anticipates that it will continue to incur, restructuring charges relating to one-time termination benefits, contract termination costs and other asset-related expenses in connection with the restructuring. The Company currently estimates that the pre-tax charges resulting from the restructuring will be between $3.0 million and $5.0 million. The Company began to incur these amounts in the fourth quarter of 2005 and expects to continue to incur them up through and including the second quarter of 2006. Substantially all of the pre-tax charges are expected to be cash expenditures.
      During the fourth quarter of 2005, the Company recorded pre-tax restructuring charges of $2.3 million. The restructuring charges primarily consist of one-time termination benefits, contract termination costs and

other asset-related expenses. Cumulative charges for employee severance as shown in the table below relate to 65 employees of which 55 were severed as of December 31, 2005.

Restructuring and Streamlining of European Operations
      Effective January 2005, the Company’s Board of Directors approved the initiation and implementation of a restructuring of certain activities related to the Company’s European operations. The restructuring seeks to optimize operations, improve resource allocation and create a scalable, lower cost and more efficient operating model for the Company’s European research and development (R&D) and commercial activities. Specifically, the restructuring involves moving key European R&D and select commercial functions from the Company’s Mougins, France and other European locations to the Company’s Irvine, California, High Wycombe, U.K. and Dublin, Ireland facilities and streamlining functions in the Company’s European management services group.
      The Company has incurred, and anticipates that it will continue to incur, restructuring charges and charges relating to severance, relocation and one-time termination benefits, payments to public employment and training programs, transition and duplicate operating expenses, contract termination costs and capital and other asset-related expenses in connection with the restructuring. The Company currently estimates that the pre-tax charges resulting from the restructuring, including transition and duplicate operating expenses, will be between $46 million and $51 million and capital expenditures will be between $3 million and $4 million. Of the total amount of pre-tax charges and capital expenditures, approximately $43 million to $48 million are expected to be cash expenditures.
      The foregoing estimates are based on assumptions relating to, among other things, a reduction of approximately 155 positions, principally R&D and selling, general and administrative positions in the affected European locations. These workforce reduction activities began in the first quarter of 2005 and are expected to be substantially completed by the close of the second quarter of 2006. Charges associated with the workforce reduction, including severance, relocation and one-time termination benefits, and payments to public employment and training programs, are currently expected to total approximately $30 million to $31 million.
      Estimated charges include approximately $11 million to $13 million for contract and lease termination costs and asset write-offs (primarily for accelerated amortization related to leasehold improvements in facilities to be exited) and a loss on the possible sale of the Company’s Mougins facility. The Company began to record these costs in the fourth quarter of 2005 and they are expected to continue up through and including the second quarter of 2006.
      Estimated transition related expenses include, among other things, legal, consulting, recruiting, information system implementation costs and taxes. The Company also expects to incur duplicate operating expenses during the transition period to ensure that job knowledge and skills are properly transferred to new employees. Transition and duplicate operating expenses are currently estimated to total approximately $5 million to

$7 million. The Company began to record these costs in the first quarter of 2005 and they are expected to continue up through and including the second quarter of 2006.
      The Company expects to incur additional capital expenditures for leasehold improvements (primarily at a new facility in the United Kingdom to accommodate increased headcount). These capital expenditures are currently estimated to be between approximately $3 million and $4 million. The Company began to record these expenditures in the third quarter of 2005 and they are expected to continue up through and including the second quarter of 2006.
      During the year ended December 31, 2005, the Company recorded pre-tax restructuring charges of $28.9 million related to the restructuring of the Company’s European operations. The restructuring charges primarily consist of employee severance, one-time termination benefits, employee relocation and other costs. The following table presents the cumulative restructuring activities through December 31, 2005:
                         
    Employee   Other    
    Severance   Costs   Total

      Employee severance in the preceding table relates to 155 employees, of which 67 were severed as of December 31, 2005. Employee severance charges were based on social plans in France and Italy, and the Company’s severance practices for employees in the other affected European countries. During 2005, the Company also recorded $5.6 million of transition/duplicate operating expenses associated with the European restructuring activities. Transition/duplicate operating expenses consisted primarily of salaries, travel, communications, recruitment and consulting costs. Transition/duplicate operating expenses of $0.3 million in cost of sales, $3.8 million in selling, general and administrative expenses and $1.5 million in research and development expenses have been included in the Company’s consolidated statements of operations for the year ended December 31, 2005.
Termination of Manufacturing and Supply Agreement with Advanced Medical Optics
      In October 2004, the Company’s Board of Directors approved certain restructuring activities related to the termination in June 2005 of the Company’s manufacturing and supply agreement with AMO. Under the manufacturing and supply agreement, which was entered into in connection with the AMO spin-off, the Company agreed to manufacture certain contact lens care products and VITRAX, a surgical viscoelastic, for AMO for a period of up to three years ending in June 2005. As part of the termination of the manufacturing and supply agreement, the Company eliminated certain manufacturing positions at the Company’s Westport, Ireland; Waco, Texas; and Guarulhos, Brazil manufacturing facilities.
      As of December 31, 2005, the Company recorded cumulative pre-tax restructuring charges of $21.6 million related to the termination of the manufacturing and supply agreement. These charges primarily include statutory severance and one-time termination benefits related to the reduction in the Company’s workforce of 323 employees and the write-off of assets previously used for contract manufacturing. The pre-tax charges are net of tax credits received under qualifying government-sponsored employment programs.
      As of December 31, 2005, the Company had completed substantially all activities related to the termination of the manufacturing and supply agreement. The Company expects to record an additional

$2.0 million to $3.0 million in pre-tax restructuring charges during the first three quarters of 2006 to complete the refurbishment of facilities previously used for contract manufacturing.
      The following table presents the cumulative restructuring activities through December 31, 2005 resulting from the scheduled termination of the manufacturing and supply agreement with AMO:

      The remaining balance at December 31, 2005 is comprised of accrued one-time termination benefits of $0.1 million. Included in other costs within the table above is $0.2 million of inventory write-offs that have been recorded as a component of “Cost of sales” in the consolidated statements of operations.
      During the year ended December 31, 2005, the Company reduced by $1.6 million the remaining balance of other accrued costs associated with restructuring costs and asset write-offs previously recorded in connection with the spin-off of AMO in 2002. This reduction in other accrued costs was included in “Restructuring charge (reversal), net” for the year ended December 31, 2005. At December 31, 2005, there were no remaining accrued costs associated with the 2002 spin-off of AMO.
Note 3: Acquisitions
Oculex Pharmaceuticals, Inc.
      On November 20, 2003, the Company purchased all of the outstanding equity interests of Oculex Pharmaceuticals, Inc. (Oculex), a privately held company, for an aggregate purchase price of approximately $223.8 million, net of cash acquired, including transaction costs of $1.6 million and $6.1 million in other assets, comprised principally of notes receivable, an equity investment and certain deferred tax assets related to Oculex. The acquisition was accounted for by the purchase method of accounting and accordingly, the consolidated statements of operations include the results of Oculex beginning November 20, 2003. In conjunction with the acquisition, the Company recorded a charge to in-process research and development expense of $179.2 million during 2003 for an acquired in-process research and development asset which the Company determined was not yet complete and had no alternative future uses in its current state. This asset is Oculex’s lead investigational product, Posurdex®, which is a proprietary, bioerodable, sustained release implant that delivers dexamethasone to the targeted disease site at the back of the eye. Phase 2 clinical trials for Posurdex® have already been completed, and the Company has initiated Phase 3 clinical trials for macular edema associated with diabetes and vein occlusions. Additionally, the Company determined that the assets acquired also included a proprietary technology drug delivery platform which had alternative future uses in its current state, which the Company separately valued and capitalized as core technology. The core technology is a versatile bioerodable polymer drug delivery technology which can be used for sustained local delivery of compounds to the eye.
