| ZIMMER HOLDINGS INC                              ITEM 1A Risk Factors               Risk factors which could cause actual results to differ from our     expectations and which could negatively impact our financial condition and     results of operations are discussed below and elsewhere in this report | 
    
    
      | The     risks and uncertainties described below are not the only ones we face | 
    
    
      | Additional risks and uncertainties not presently known to us or that are     currently not believed to be significant to our business may also affect our     actual results and could harm our business, financial condition and results     of operations | 
    
    
      | If any of the risks or uncertainties described below or any     additional risks and uncertainties actually occur, our business, results of     operations  and  financial condition could be materially and adversely     affected | 
    
    
      | RISKS RELATED TO OUR INDUSTRY              Our success depends on our ability to effectively develop and market     our products against those of our competitors | 
    
    
      | We operate in a highly competitive environment | 
    
    
      | Our present or future     products  could  be rendered obsolete or uneconomical by technological     advances by one or more of our present or future competitors or by other     therapies, including orthobiological therapies | 
    
    
      | To remain competitive, we     must continue to develop and acquire new products and technologies | 
    
    
      | In the global markets for reconstructive orthopaedic implants, trauma     products and other orthopaedic products, a limited number of competitors,     including DePuy Orthopaedics, Inc | 
    
    
      | and Smith & Nephew plc, compete with us for the majority of product sales | 
    
    
      | (a subsidiary of Medtronic, Inc | 
    
    
      | ), DePuy Spine (a     subsidiary of Johnson & Johnson), Synthes, Inc, Stryker Corporation and     EBI, LP (a subsidiary of Biomet, Inc | 
    
    
      | In the dental reconstructive     implant  category, we compete primarily with Nobel Biocare Holding AG,     Straumann Holding AG, and Implant Innovations, Inc | 
    
    
      | Competition is primarily on the basis of:       •  technology;     •  innovation;     •  quality;     •  reputation;     •  relationships with customers; and     •  service | 
    
    
      | In local markets outside of the United States, other factors influence     competition as well, including:       •  local distribution systems;     •  complex regulatory environments; and     •  differing medical philosophies and product preferences | 
    
    
      | Our competitors may:       •  have greater financial, marketing and other resources than us;     •  respond more quickly to new or emerging technologies;     •  undertake more extensive marketing campaigns;     •  adopt more aggressive pricing policies; or     •  be more successful in attracting potential customers, employees and     strategic partners | 
    
    
      | Any of these factors, alone or in combination, could cause us to have     difficulty maintaining or increasing sales of our products | 
    
    
      | If third-party payors decline to reimburse our customers for our     products or reduce reimbursement levels, the demand for our products may     decline and our ability to sell our products profitably may be harmed | 
    
    
      | We sell our products and services to hospitals, doctors, dentists and     other health care providers, all of which receive reimbursement for the     health care services provided to their patients from third-party payors,     such as domestic and international government programs, private insurance     plans  and  managed  care  programs | 
    
    
      | These third-party payors may deny     reimbursement if they determine that a device used in a procedure was not in     accordance with cost-effective treatment methods, as determined by the     third-party payor, or was used for an unapproved indication | 
    
    
      | Third-party     payors  may  also decline to reimburse for experimental procedures and     devices | 
    
    
      | If our products are not considered cost-effective by third-party     payors, our customers may not be reimbursed for our products | 
    
    
      | In addition, third-party payors are increasingly attempting to contain     health care costs by limiting both coverage and the level of reimbursement     for medical products and services | 
    
    
      | For example, managed care programs often     prescribe only those orthopaedic recovery products that match a patient as     to age, need for mobility and other parameters in an effort to provide more     cost-effective care | 
    
    
      | If third-party payors reduce reimbursement levels to     hospitals and other health care providers for our products, demand for our     products may decline or we may experience pressure to reduce the prices of     our products, which could have a material adverse effect on sales, financial     condition and results of operation | 
    
    
      | In international markets, where the movement toward health care reform     and the development of managed care are generally not as advanced as in the     United States, we have experienced downward pressure on product pricing and     other  effects  of  health  care  reform | 
    
    
      | In  Japan,  for  example, a     government-operated insurance system reimburses customers                                                                           15       _________________________________________________________________    [69]Table of Contents       ZIMMER HOLDINGS, INC AND SUBSIDIARIES 2005 FORM 10-K         for our products | 
    
    
      | Under this system, the Japanese government periodically     reviews and reduces the reimbursement levels for products | 
    
    
      | If the Japanese     government continues to reduce the reimbursement level for orthopaedic     products, our sales, financial condition and results of operation may be     adversely affected | 
    
    
      | We are subject to cost-containment efforts of healthcare purchasing     organizations, which may have a material adverse effect on our financial     condition and results of operations | 
    
    
      | Many existing and potential customers for our products have combined to     form group purchasing organizations in an effort to contain costs | 
    
    
      | Group     purchasing organizations negotiate pricing arrangements with medical supply     manufacturers  and  distributors, and these negotiated prices are made     available to a group purchasing organization’s affiliated hospitals and     other  members | 
    
    
      | If we are not one of the providers selected by a group     purchasing organization, affiliated hospitals and other members may be less     likely to purchase our products, and if the group purchasing organization     has negotiated a strict compliance contract for another manufacturer’s     products, we may be precluded from making sales to members of the group     purchasing organization for the duration of the contractual arrangement | 
    
    
      | Our     failure to respond to the cost-containment efforts of group purchasing     organizations may cause us to lose market share to our competitors and could     have a material adverse effect on our sales, financial condition and results     of operations | 
    
    
      | We are involved in an ongoing investigation by the United States     Department of Justice of companies in the orthopaedics industry, the results     of  which  may  have a material adverse effect on our sales, financial     condition and results of operations | 
    
    
      | On March 31, 2005, we received a subpoena from the United States     Department of Justice through the United States Attorney’s Office in Newark,     New  Jersey,  requesting  documents related to consulting contracts or     professional  service agreements we have with orthopaedic surgeons | 
    
    
      | We     understand that similar inquiries were directed to at least four other     companies  in the orthopaedics industry | 
    
    
      | We are cooperating fully with     federal authorities with regard to this matter | 
    
    
      | If, as a result of this     investigation, we are found to have violated one or more applicable laws,     our  business,  financial condition and results of operations could be     materially adversely affected | 
    
    
      | If some of our existing business practices     are challenged as unlawful, we may have to change those practices, which     could have a material adverse effect on our business, financial condition     and results of operations | 
    
    
      | We and our customers are subject to various governmental regulations     and we may incur significant expenses to comply with these regulations and     develop products compatible with these regulations | 
    
    
      | The medical devices we design, develop, manufacture and market are     subject to rigorous regulation by the FDA and numerous other Federal, state     and foreign governmental authorities | 
    
    
      | The process of obtaining regulatory     approvals to market a medical device, particularly from the FDA and certain     foreign governmental authorities, can be costly and time consuming and     approvals might not be granted for future products on a timely basis, if at     all | 
    
    
      | Delays in receipt of, or failure to obtain, approvals for future     products could result in delayed realization of product revenues or in     substantial additional costs which could have a material adverse effect on     our business or results of operations | 
    
    
      | In addition, if we fail to comply with applicable FDA medical device or     other material regulatory requirements, including, for example, the Quality     System Regulation, recordkeeping regulations, labeling requirements and     adverse event reporting regulations, that failure could result in, among     other things:       •  warning letters;     •  fines or civil penalties;     •  injunctions;     •  repairs, replacements or refunds;     •  recalls or seizures of products;     •  total or partial suspension of production;     •  the US Food and Drug Administration’s refusal to grant future premarket     clearances or approvals;     •  withdrawals or suspensions of current product applications; and     •  criminal prosecution | 
    
    
      | Any of these actions, in combination or alone, could have a material     adverse  effect  on  our  business, financial condition and results of     operations | 
    
    
      | In many of the foreign countries in which we market our products, we     are subject to regulations affecting, among other things:       •  clinical efficacy;     •  product standards;     •  packaging requirements;     •  labeling requirements;     •  import/export restrictions;     •  tariff regulations;     •  duties; and     •  tax requirements | 
    
    
      | Many of the regulations applicable to our devices and products in these     countries, such as the European Medical Devices Directive, are similar to     those of the FDA In addition, in many countries the national health or     social security organizations require our products to be qualified before     they can be marketed with the benefit of reimbursement eligibility | 
    
    
      | Failure     to receive or delays in the receipt of, relevant foreign qualifications also     could have a material adverse effect on our business, financial condition     and results of operations | 
    
    
      | As  both  the  FDA and foreign government regulators have become     increasingly stringent, we may be subject to more rigorous regulation by     governmental authorities in the future | 
    
    
      | Our products and operations are also     often subject to the rules of industrial standards bodies, such as the     International Standards Organization | 
    
    
      | If we fail to adequately address any     of these regulations, our business will be harmed | 
    
    
      | We are subject to health care fraud and abuse regulations that could     require us to change our       16       _________________________________________________________________    [70]Table of Contents       ZIMMER HOLDINGS, INC AND SUBSIDIARIES 2005 FORM 10-K         business practices and restrict our operations in the future | 
    
    
      | Violations of these laws are punishable by criminal     and/or civil sanctions, including, in some instances, fines, imprisonment     and, within the United States, exclusion from participation in government     healthcare programs, including Medicare, Medicaid, Veterans Administration     (VA) health programs and Civilian Health and Medical Program Uniformed     Service (CHAMPUS) | 
    
    
      | The scope and enforcement of these laws and regulations     are uncertain and subject to rapid change | 
    
    
      | Because of the far-reaching and     uncertain nature of these laws, we are required to monitor our practices to     remain in compliance with these laws | 
    
    
      | If we were to violate one or more of     these laws, our business, financial condition and results of operations     could  be  materially adversely affected | 
    
    
      | If there is a change in law,     regulation  or administrative or judicial interpretations, some of our     existing  business practices could be challenged as unlawful and, as a     result, we may have to change those practices, which could have a material     adverse  effect  on  our  business, financial condition and results of     operations | 
    
    
      | We may incur product liability losses, and insurance coverage may be     inadequate or unavailable to cover these losses | 
    
    
      | Our business is subject to potential product liability risks that are     inherent in the design, development, manufacture and marketing of medical     devices | 
    
    
      | Our  products  are often used in surgical and intensive care     settings | 
    
    
      | In addition, some of the medical devices we manufacture and sell     are designed to be implanted in the human body for long periods of time | 
    
    
      | In     the ordinary course of business, we are the subject of product liability     lawsuits alleging that component failures, manufacturing flaws, design     defects or inadequate disclosure of product-related risks or product-related     information resulted in an unsafe condition or injury to patients | 
    
    
      | Product     liability lawsuits and claims, safety alerts or product recalls, regardless     of their ultimate outcome, could have a material adverse effect on our     business and reputation and on our ability to attract and retain customers | 
    
    
      | As part of our risk management policy, we maintain third-party product     liability insurance coverage | 
    
    
      | However, product liability claims against us     may exceed the coverage limits of our insurance policies or cause us to     record a self-insured loss | 
    
    
      | Even if any product liability loss is covered by     an insurance policy, these policies may have substantial retentions or     deductibles that provide that we will not receive insurance proceeds until     the losses incurred exceed the amount of those retentions or deductibles | 
    
    
      | We     will be responsible for paying any losses that are below those retentions or     deductibles | 
    
    
      | A product liability claim in excess of applicable insurance     could have a material adverse effect on our business, financial position and     results of operations | 
    
    
      | RISKS RELATED TO OUR BUSINESS               If  we  fail  to effectively utilize the skills and knowledge of     orthopaedic surgeons, customers may not buy our products and our revenue and     profitability may decline | 
    
    
      | We maintain professional relationships with a number of orthopaedic     surgeons who assist in product research and development and advise us on how     to satisfy the full range of surgeon and patient needs | 
    
    
      | These professionals     speak about our products at medical seminars, assist in the training of     other professionals in the use of our products and provide us with feedback     on  the  industry’s acceptance of our new products | 
    
    
      | The failure of our     products to retain the support of orthopaedic surgeons, who frequently     recommend products or are involved in product selection decisions, or the     failure  of our new products to secure and retain similar support from     surgeons, could have a material adverse effect on our business, financial     condition and results of operations | 
    
    
      | If we fail to retain the independent agents and distributors upon whom     we rely heavily to market our products, customers may not buy our products     and our revenue and profitability may decline | 
    
    
      | Our marketing success in the United States and abroad depends largely     upon  our agents’ and distributors’ sales and service expertise in the     marketplace | 
    
    
      | Many of these agents have developed professional relationships     with existing and potential customers because of their detailed knowledge of     products and instruments | 
    
    
      | Many commonly provide operating room personnel     with implant and instrument product training as well as product support in     the operating room | 
    
    
      | A loss of a significant number of these agents could     have a material adverse effect on our business, financial condition and     results of operations | 
    
    
      | If some of the business practices of our independent     sales agents and distributors are challenged as unlawful, they may have to     change those practices, which could have a material adverse effect on our     business, financial condition and results of operations | 
    
    
      | If we do not introduce new products in a timely manner, our products     may become obsolete over time, customers may not buy our products and our     revenue and profitability may decline | 
    
    
      | Demand for our products may change, in certain cases, in ways we may     not anticipate because of:       •  evolving customer needs;       •  changing demographics;       •  slowing industry growth rates;       •  declines in the reconstructive implant market;       •  the introduction of new products and technologies;       •  evolving surgical philosophies; and       •  evolving industry standards | 
    
    
      | Without the timely introduction of new products and enhancements, our     products may become obsolete over time | 
    
    
      | If that happens, our revenue and     operating results would suffer | 
    
    
      | The success of our new product offerings     will depend on several factors, including our ability to:       •  properly identify and anticipate customer needs;       •  commercialize new products in a timely manner;                                                                           17       _________________________________________________________________    [71]Table of Contents       ZIMMER HOLDINGS, INC AND SUBSIDIARIES 2005 FORM 10-K         •  manufacture and deliver instruments and products in sufficient volumes on     time;       •  differentiate our offerings from competitors’ offerings;       •  achieve positive clinical outcomes for new products;       •   satisfy  the increased demands by healthcare payors, providers and     patients for shorter hospital stays, faster post-operative recovery and     lower-cost procedures;       •   innovate  and  develop new materials, product designs and surgical     techniques; and       •  provide adequate medical education relating to new products and attract     key surgeons to advocate these new products | 
    
    
      | In addition, new materials, product designs and surgical techniques     that we develop may not be accepted quickly, in some or all markets, because     of, among other factors:       •  entrenched patterns of clinical practice;       •  the need for regulatory clearance; and       •  uncertainty with respect to third-party reimbursement | 
    
    
      | Moreover, innovations generally require a substantial investment in     research and development before we can determine their commercial viability     and  we  may  not  have  the financial resources necessary to fund the     production | 
    
    
      | In  addition, even if we are able to successfully develop     enhancements or new generations of our products, these enhancements or new     generations of products may not produce revenue in excess of the costs of     development and they may be quickly rendered obsolete by changing customer     preferences or the introduction by our competitors of products embodying new     technologies or features | 
    
    
      | We conduct a significant amount of our sales activity outside of the     United States, which subjects us to additional business risks and may cause     our profitability to decline due to increased costs | 
    
    
      | Because we sell our products in more than 100 countries, our business     is subject to risks associated with doing business internationally | 
    
    
      | In 2005,     we derived approximately dlra1cmam344 million, or 41prca of our total revenue, from     sales of our products outside of the United States | 
    
    
      | We intend to continue to     pursue growth opportunities in sales internationally, which could expose us     to additional risks associated with international sales and operations | 
    
    
      | Our     international operations are, and will continue to be, subject to a number     of risks and potential costs, including:       •  changes in foreign medical reimbursement policies and programs;       •  unexpected changes in foreign regulatory requirements;       •  differing local product preferences and product requirements;       •  fluctuations in foreign currency exchange rates;       •  diminished protection of intellectual property in some countries outside     of the United States;       •  trade protection measures and import or export licensing requirements;       •  difficulty in staffing and managing foreign operations;       •  labor force instability;       •  differing labor regulations;       •  potentially negative consequences from changes in tax laws; and       •  political and economic instability | 
    
    
      | Any of these factors may, individually or as a group, have a material     adverse  effect  on  our  business, financial condition and results of     operations | 
    
    
      | We  are  subject  to  risks  arising from currency exchange rate     fluctuations, which can increase our costs and may cause our profitability     to decline | 
    
    
      | A substantial portion of our foreign generated revenues are generated     in Europe and Japan | 
    
    
      | The United States dollar value of our foreign-generated     revenues  varies with currency exchange rate fluctuations | 
    
    
      | Significant     increases in the value of the United States dollar relative to the Euro or     the Japanese Yen, as well as other currencies, could have a material adverse     effect on our results of operations | 
    
    
      | We address currency risk management     through regular operating and financing activities, and on a limited basis,     through  the  use  of derivative financial instruments | 
    
    
      | The derivative     financial instruments we enter into are in the form of foreign exchange     forward contracts with major financial institutions | 
    
    
      | The forward contracts     are designed to hedge anticipated foreign currency transactions, primarily     intercompany sale and purchase transactions, for periods consistent with     commitments | 
    
    
      | Realized and unrealized gains and losses on these contracts     that  qualify  as  cash  flow hedges are temporarily recorded in other     comprehensive income, then recognized in earnings when the hedged item     affects net earnings | 
    
    
      | We may fail to adequately protect our proprietary technology and other     intellectual property, which would allow competitors or others to take     advantage of our research and development efforts | 
    
    
      | Our  long-term  success largely depends on our ability to market     technologically competitive products | 
    
    
      | If we fail to obtain or maintain     adequate intellectual property protection, we may not be able to prevent     third parties from using our proprietary technologies | 
    
    
      | Also, our currently     pending or future patent applications may not result in issued patents | 
    
    
      | In     the  United States, patent applications are confidential for 18 months     following their filing, and because third parties may have filed patent     applications for technology covered by our pending patent applications     without our being aware of those applications, our patent applications may     not have priority over patent applications of others | 
    
    
      | In addition, our     issued patents may not contain claims sufficiently broad to protect us     against third parties with similar technologies or products, or provide us     with  any competitive advantage | 
    
    
      | If a third party initiates litigation     regarding our patents, our collaborators’ patents, or those patents for     which we have license rights, and is successful, a court could declare our     patents invalid or unenforceable or limit the scope of coverage of those     patents | 
    
    
      | The United States Patent and Trademark Office (USPTO) and the courts     have not consistently treated the breadth of claims allowed or interpreted     in orthopaedic reconstructive implant and biotechnology patents | 
    
    
      | If the     USPTO or the courts begin to allow or interpret claims more       18       _________________________________________________________________    [72]Table of Contents       ZIMMER HOLDINGS, INC AND SUBSIDIARIES 2005 FORM 10-K         broadly, the incidence and cost of patent interference proceedings and the     risk of infringement litigation will likely increase | 
    
    
      | On the other hand, if     the USPTO or the courts begin to allow or interpret claims more narrowly,     the value of our proprietary rights may be reduced | 
    
    
      | Any changes in, or     unexpected interpretations of, the patent laws may adversely affect our     ability to enforce our patent position | 
    
    
      | In addition, intellectual property rights may be unavailable or limited     in some foreign countries, which could make it easier for competitors to     capture market position | 
    
    
      | Competitors may also capture market share from us     by  designing products that mirror the capabilities of our products or     technology without infringing our intellectual property rights | 
    
    
      | If we do not     obtain sufficient international protection for our intellectual property,     our competitiveness in international markets could be impaired, which would     limit our growth and future revenue | 
    
    
      | We also rely upon trade secrets, proprietary know-how, and continuing     technological innovation to remain competitive | 
    
    
      | We attempt to protect this     information with security measures, including the use of confidentiality     agreements with our employees, consultants, and corporate collaborators | 
    
    
      | These individuals may breach these agreements and any remedies available to     us may be insufficient to compensate our damages | 
    
    
      | Furthermore, our trade     secrets, know-how and other technology may otherwise become known or be     independently discovered by our competitors | 
    
    
      | We may be subject to intellectual property litigation and infringement     claims, which could cause us to incur significant expenses or prevent us     from selling our products | 
    
    
      | A  successful  claim  of  patent  or other intellectual property     infringement against us could adversely affect our growth and profitability,     in some cases materially | 
    
    
      | From time to time, we receive notices from third     parties  of  potential  infringement  and  receive claims of potential     infringement | 
    
    
      | We may be unaware of intellectual property rights of others     that may cover some of our technology | 
    
    
      | If someone claims that our products     infringed their intellectual property rights, any resulting litigation could     be costly and time consuming and would divert the attention of management     and  key  personnel  from other business issues | 
    
    
      | The complexity of the     technology involved and the uncertainty of intellectual property litigation     increase these risks | 
    
    
      | Claims of intellectual property infringement also     might  require  us to enter into costly royalty or license agreements | 
    
    
      | However, we may be unable to obtain royalty or license agreements on terms     acceptable to us or at all | 
    
    
      | We also may be subject to significant damages or     an injunction preventing us from manufacturing, selling or using some of our     products in the event of a successful claim of patent or other intellectual     property  infringement | 
    
    
      | Any of these adverse consequences could have a     material adverse effect on our business, financial condition and results of     operations | 
    
    
      | We may complete additional acquisitions, which could increase our costs     or liabilities or be disruptive | 
    
    
      | We intend to continue to look for additional strategic acquisitions | 
    
    
      | We     may  not  be  able to complete additional acquisitions or to integrate     successfully any acquired businesses without substantial expense, delay or     other operational or financial problems | 
    
    
      | Acquiring and integrating new     businesses involves risk, including the following:       •  we may need to divert more management resources to integration than we     planned, which may adversely affect our ability to pursue other more     profitable activities;       •  the difficulties of integration may be increased if we need to integrate     geographically separated organizations, personnel with disparate business     backgrounds and companies with different corporate cultures;     •   we  may not eliminate as many redundant costs as we anticipated in     selecting our acquisition candidates; and       •  one or more of our acquisition candidates also may have liabilities or     adverse operating issues that we failed to discover through our diligence     prior to the acquisition | 
    
    
      | If we are unable to form strategic alliances, or if our strategic     alliances fail to achieve their objectives, our operating results will be     negatively impacted | 
    
    
      | Several of our strategic initiatives involve alliances with other     orthopaedic and biotechnology companies | 
    
    
      | These include our agreement with     Revivicor, Inc | 
    
    
      | relating to orthopaedic tissue technology, our collaboration     with ISTO Technologies, Inc | 
    
    
      | relating to regenerative cartilage technology     and our distribution agreement with Heraeus relating to orthopaedic bone     cement products | 
    
    
      | The success of these and similar arrangements is largely     dependent on technology and other intellectual property contributed by our     strategic partners or the resources, efforts, and skills of these partners | 
    
    
      | Disputes and difficulties in such relationships are common, often due to     conflicting priorities or conflicts of interest | 
    
    
      | Merger and acquisition     activity may exacerbate these conflicts | 
    
    
      | The benefits of these alliances are     reduced or eliminated when strategic partners:       •  terminate the agreements or limit our access to the underlying     intellectual property;       •  fail to devote financial or other resources to the alliances and thereby     hinder or delay development, manufacturing or commercialization activities;       •   fail  to  successfully  develop,  manufacture or commercialize any     products; or       •  fail to maintain the financial resources necessary to continue financing     their portion of the development, manufacturing, or commercialization costs     or their own operations | 
    
    
      | Furthermore,  under some of our strategic alliances, we may make     milestone payments well in advance of commercialization of products with no     assurance that we will ever recoup these payments | 
    
    
      | We also may make equity     investments in our strategic partners | 
    
    
      | These investments may decline in     value and result in our incurring financial statement charges in the future | 
    
    
      | We depend on a limited number of suppliers for some key raw materials     and outsourced activities | 
    
    
      | We use a number of suppliers for raw materials we need to manufacture     our products and to outsource some key manufacturing activities | 
    
    
      | These     suppliers must provide the materials and perform the activities to our     standards for us to                                                                           19       _________________________________________________________________    [73]Table of Contents       ZIMMER HOLDINGS, INC AND SUBSIDIARIES 2005 FORM 10-K         meet our quality and regulatory requirements | 
    
    
      | Some key raw materials and     outsourced activities can only be obtained from a single source or a limited     number of sources | 
    
    
      | A prolonged disruption or other inability to obtain these     materials or activities could materially and adversely affect our ability to     satisfy demand for our products, which could have a material adverse effect     on our business, financial condition and results of operations | 
    
    
      | Our future profitability may be affected by changes to our product     category and region sales mix | 
    
    
      | Reconstructive implants produce the highest operating profit margins     among our product categories | 
    
    
      | These products accounted for approximately     83 percent of 2005 net sales | 
    
    
      | Sales in our Americas region accounted for     approximately 59 percent of 2005 net sales | 
    
    
      | Sales in the Americas region     produce the highest operating profit margins in the geographic markets in     which we operate | 
    
    
      | While we expect net sales of reconstructive implants and     net sales in the Americas region to remain strong, changes to our product     category mix or our region sales mix could adversely affect our future     profitability |
