Commitments and Contingencies

17. Commitments and Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business. For a discussion of our tax contingencies, see Note 5D. Taxes on Income: Tax Contingencies.

LEGAL PROCEEDINGS

Our non-tax contingencies include, among others, the following:

• Patent litigation, which typically involves challenges to the coverage and/or validity of our patents on various products or processes. We are the plaintiff in the vast majority of these actions. An adverse outcome in actions in which we are the plaintiff could result in a loss of patent protection for the drug at issue, a significant loss of revenues from that drug and impairments of any associated assets.

• Product liability and other product-related litigation, which can include personal injury, consumer, off-label promotion, securities-law, antitrust and breach of contract claims, among others, often involves highly complex issues relating to medical causation, label warnings and reliance on those warnings, scientific evidence and findings, actual provable injury and other matters.

• Commercial and other litigation, which can include merger-related and product-pricing claims and environmental claims and proceedings, can involve complexities that will vary from matter to matter.

• Government investigations, which often are related to the extensive regulation of pharmaceutical companies by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that our claims and defenses in these matters are substantial, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid and/or accrued.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies heavily on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions. For information about the risks associated with estimates and assumptions, see Note 1C. Significant Accounting Policies: Estimates and Assumptions.

The principal pending matters to which we are a party are discussed below. In determining whether a pending matter is a principal matter, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the Company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent. As a result of considering qualitative factors in our determination of principal matters, there are some matters discussed below with respect to which management believes that the likelihood of possible loss in excess of amounts accrued is remote.

A. Patent Litigation

Like other pharmaceutical companies, we are involved in numerous suits relating to our patents, including but not limited to those discussed below. Most of the suits involve claims by generic drug manufacturers that patents covering our products, processes or dosage forms are invalid and/or do not cover the product of the generic manufacturer. Also, counterclaims, as well as various independent actions, have been filed claiming that our assertions of, or attempts to enforce, our patent rights with respect to certain products constitute unfair competition and/or violations of the antitrust laws. In addition to the challenges to the U.S. patents on a number of our products that are discussed below, we note that the patent rights to certain of our products are being challenged in various other countries.

ACTIONS IN WHICH WE ARE THE PLAINTIFF AND CERTAIN RELATED ACTIONS

Lipitor (atorvastatin)

In November 2008, Apotex Inc. notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Lipitor. In December 2008, we filed patent-infringement suits against Apotex Inc. in the U.S. District Court for the District of Delaware and the U.S. District Court for the Northern District of Illinois. In August 2009, our action in the District of Delaware was transferred to the Northern District of Illinois and consolidated with our pending action there. Apotex Inc. asserts the invalidity of our patent covering the crystalline form of atorvastatin, which (including the six-month pediatric exclusivity period) expires in 2017. We assert the infringement of our crystalline patent and are defending against the allegations of invalidity.

In November 2011, our previously reported patent-infringement actions related to Lipitor against KUDCO Ireland, Ltd. and Kremers Urban LLC and against Aurobindo Pharma Ltd. in the U.S. District Court for the District of Delaware were settled on terms that are not material to Pfizer.

Lipitor began to face generic competition in the U.S. in November 2011.

In the U.K., while the basic patent for Lipitor expired in November 2011, the exclusivity period has been extended by six months to May 2012 by virtue of the supplementary protection certificate and pediatric extension. In September 2011, Dr. Reddy’s Laboratories (UK) Limited filed an action in the High Court of Justice seeking revocation of the six-month pediatric extension. We are defending this action, which is based upon the interpretation of the EU Pediatric Medicines Regulation.

Caduet (atorvastatin/amlodipine combination)

In December 2011, our previously reported patent-infringement action related to Caduet against Sandoz, Inc., a division of Novartis AG (Sandoz), in the U.S. District Court for the District of Delaware was voluntarily dismissed by us.

Caduet began to face generic competition in the U.S. in November 2011.

Viagra (sildenafil)

In March 2010, we brought a patent-infringement action in the U.S. District Court for the Eastern District of Virginia against Teva Pharmaceuticals USA, Inc. (Teva USA) and Teva Pharmaceutical Industries Ltd. (Teva Pharmaceutical Industries), which had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Viagra. Teva USA and Teva Pharmaceutical Industries assert the invalidity and non-infringement of the Viagra use patent, which expires in 2019, but have not challenged the basic patent, which expires in 2012. In August 2011, the court ruled that our Viagra use patent is valid and infringed, thereby preventing Teva USA and Teva Pharmaceutical Industries from receiving approval for a generic version of Viagra before October 2019. In September 2011, Teva USA and Teva Pharmaceutical Industries appealed the decision to the U.S. Court of Appeals for the Federal Circuit.

In October 2010, we filed a patent-infringement action with respect to Viagra in the U.S. District Court for the Southern District of New York against Apotex Inc. and Apotex Corp., Mylan Pharmaceuticals Inc. and Mylan Inc., Actavis, Inc. and Amneal Pharmaceuticals LLC. These generic manufacturers have filed abbreviated new drug applications with the FDA seeking approval to market their generic versions of Viagra. They assert the invalidity and non-infringement of the Viagra use patent, but have not challenged the basic patent.

In May and June 2011, respectively, Watson Laboratories Inc. (Watson) and Hetero Labs Limited (Hetero) notified us that they had filed abbreviated new drug applications with the FDA seeking approval to market their generic versions of Viagra. Each asserts the invalidity and non-infringement of the Viagra use patent. Neither has challenged the basic patent. In June and July 2011, respectively, we filed actions against Watson and Hetero in the U.S. District Court for the Southern District of New York asserting the validity and infringement of the use patent.

Sutent (sunitinib malate)

In May 2010, Mylan Pharmaceuticals Inc. notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Sutent and challenging on various grounds the Sutent basic patent, which expires in 2021, and two other patents, which expire in 2020 and 2021. In June 2010, we filed suit against Mylan Pharmaceuticals Inc. in the U.S. District Court for the District of Delaware asserting the infringement of those three patents.

Detrol and Detrol LA (tolterodine)

In January 2008, Impax Laboratories, Inc. (Impax) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Detrol LA. Impax is challenging on various grounds the basic patent, which (including the six-month pediatric exclusivity period) expires in 2012, and three formulation patents, which (including the six-month pediatric exclusivity period) expire in 2020. We filed an action against Impax in the U.S. District Court for the Southern District of New York asserting the infringement of the basic patent and two of the formulation patents. This action subsequently was transferred to the U.S. District Court for the District of New Jersey.

In March 2008 and May 2010, respectively, Sandoz and Mylan Pharmaceuticals Inc. notified us that they had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Detrol LA. They assert the invalidity and/or non-infringement of three formulation patents for Detrol LA. They have not challenged the basic patent. In June 2010, we filed actions against Sandoz and Mylan Pharmaceuticals Inc. in the U.S. District Court for the District of New Jersey asserting the infringement of two of the formulation patents.

In April 2011, Impax notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Detrol.

In June 2011, we filed an action against Impax in the U.S. District Court for the District of New Jersey asserting infringement of the basic patent.

In June 2011, Torrent Pharmaceuticals Ltd. (Torrent) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Detrol LA. Torrent asserted the invalidity and non-infringement of three formulation patents. Torrent did not challenge the basic patent. In July 2011, we filed an action against Torrent in the U.S. District Court for the District of New Jersey asserting the validity and infringement of the challenged patents. In February 2012, this action was settled on terms that are not material to Pfizer.

Lyrica (pregabalin)

Beginning in March 2009, several generic manufacturers notified us that they had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Lyrica capsules and, in the case of one generic manufacturer, Lyrica oral solution. Each of the generic manufacturers is challenging one or more of three patents for Lyrica: the basic patent, which expires in 2018, and two other patents, which expire in 2013 and 2018. Each of the generic manufacturers asserts the invalidity and/or the non-infringement of the patents subject to challenge. Beginning in April 2009, we filed actions against these generic manufacturers in the U.S. District Court for the District of Delaware asserting the infringement and validity of our patents for Lyrica. All of these cases have been consolidated in the District of Delaware.

In November 2010, Novel Laboratories, Inc. (Novel) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Lyrica oral solution and asserting the invalidity and/or infringement of our three patents for Lyrica referred to above. In January 2011, we filed an action against Novel in the U.S. District Court for the District of Delaware asserting the validity and infringement of all three patents.

Apotex Inc. notified us, in May and June 2011, respectively, that it had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Lyrica oral solution and Lyrica capsules. Apotex Inc. asserts the invalidity and non-infringement of the basic patent, as well as the seizure patent that expires in 2013. In July 2011, we filed an action against Apotex Inc. in the U.S. District Court for the District of Delaware asserting the validity and infringement of the challenged patents in connection with both of the abbreviated new drug applications.

In October 2011, Alembic Pharmaceuticals Limited (Alembic) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Lyrica capsules and asserting the invalidity of the basic patent. In December 2011, we filed an action against Alembic in the U.S. District Court for the District of Delaware asserting the validity and infringement of the basic patent.

We also have filed patent-infringement actions in Canada against certain generic manufacturers who are seeking approval to market generic versions of Lyrica capsules in that country.

Zyvox (linezolid)

In December 2009, Teva Parenteral Medicines Inc. (Teva Parenteral) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Zyvox. Teva Parenteral asserts the invalidity and non-infringement of the basic Zyvox patent, which (including the six-month pediatric exclusivity period) expires in 2015, and another patent that expires in 2021. In January 2010, we filed suit against Teva Parenteral in the U.S. District Court for the District of Delaware asserting the infringement of the basic patent.

Relpax (eletriptan)

In June 2010, we received notices from Apotex Inc. and Apotex Corp. and from Teva USA that they had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Relpax. They asserted the non-infringement of our patent covering the crystalline form of eletriptan, which expires in 2017. They did not challenge the basic patent, which expires in 2016. In July 2010, we filed actions against Apotex Inc. and Apotex Corp. and against Teva USA in the U.S. District Court for the Southern District of New York asserting the infringement of the crystalline patent. In July 2011, the action against Teva USA was settled on terms that are not material to Pfizer. In October 2011, the action against Apotex Inc. and Apotex Corp. was voluntarily dismissed by the parties without prejudice.

Protonix (pantoprazole sodium)

Wyeth has a license to market Protonix in the U.S. from Nycomed GmbH (Nycomed), which owns the patents relating to Protonix. The basic patent (including the six-month pediatric exclusivity period) for Protonix expired in January 2011.

Following their respective filings of abbreviated new drug applications with the FDA, Teva USA and Teva Pharmaceutical Industries, Sun Pharmaceutical Advanced Research Centre Ltd. and Sun Pharmaceutical Industries Ltd. (collectively, Sun) and KUDCO Ireland, Ltd. (KUDCO Ireland) received final FDA approval to market their generic versions of Protonix 20mg and 40mg delayed-release tablets. Wyeth and Nycomed filed actions against those generic manufacturers in the U.S. District Court for the District of New Jersey, which subsequently were consolidated into a single proceeding, alleging infringement of the basic patent and seeking declaratory and injunctive relief. Following the court’s denial of a preliminary injunction sought by Wyeth and Nycomed, Teva USA and Teva Pharmaceutical Industries and Sun launched their generic versions of Protonix tablets at risk in December 2007 and January 2008, respectively. Wyeth launched its own generic version of Protonix tablets in January 2008, and Wyeth and Nycomed filed amended complaints in the pending patent-infringement action seeking compensation for damages resulting from Teva USA’s, Teva Pharmaceutical Industries’ and Sun’s at-risk launches.

In April 2010, the jury in the pending patent-infringement action upheld the validity of the basic patent for Protonix. In July 2010, the court upheld the jury verdict, but it did not issue a judgment against Teva USA, Teva Pharmaceutical Industries or Sun because of their other claims relating to the patent that still are pending. Wyeth and Nycomed will continue to pursue all available legal remedies against those generic manufacturers, including compensation for damages resulting from their at-risk launches.

Separately, Wyeth and Nycomed are defendants in purported class actions brought by direct and indirect purchasers of Protonix in the U.S. District Court for the District of New Jersey. Plaintiffs seek damages, on behalf of the respective putative classes, for the alleged violation of antitrust laws in connection with the procurement and enforcement of the patents for Protonix. These purported class actions have been stayed pending resolution of the underlying patent litigation in the U.S. District Court for the District of New Jersey.

Rapamune (sirolimus)

In March 2010, Watson and Ranbaxy Laboratories Limited (Ranbaxy) notified us that they had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Rapamune. Watson and Ranbaxy assert the invalidity and non-infringement of a method-of-use patent which (including the six-month pediatric exclusivity period) expires in 2014 and a solid-dosage formulation patent which (including the six-month pediatric exclusivity period) expires in 2018. In April 2010, we filed actions against Watson and Ranbaxy in the U.S. District Court for the District of Delaware and against Watson in the U.S. District Court for the Southern District of Florida asserting the infringement of the method-of-use patent. In June 2010, our action in the Southern District of Florida was transferred to the District of Delaware and consolidated with our pending action there.

Tygacil (tigecycline)

In October 2009, Sandoz notified Wyeth that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Tygacil. Sandoz asserts the invalidity and non-infringement of two of Wyeth’s patents relating to Tygacil, including the basic patent, which expires in 2016. In December 2009, Wyeth filed suit against Sandoz in the U.S. District Court for the District of Delaware asserting infringement of the basic patent.

Avinza (morphine sulfate)

King Pharmaceuticals, Inc. (King) and Elan Pharma International LTD (EPI) brought a patent-infringement action in the U.S. District Court for the District of New Jersey against Sandoz in July 2009 as the result of its abbreviated new drug application with the FDA seeking approval to market a generic version of Avinza. Sandoz is challenging a formulation patent for Avinza, which is owned by EPI, that expires in 2017.

EpiPen

King brought patent-infringement actions against Sandoz in the U.S District Court for the District of New Jersey in July 2010 and against Teva Pharmaceutical Industries and Intelliject, Inc. (Intelliject) in the U.S. District Court for the District of Delaware in August 2009 and January 2011, respectively, as the result of their abbreviated new drug applications with the FDA seeking approval to market epinephrine injectable products. The two actions in Delaware subsequently were consolidated. Sandoz and Teva Pharmaceutical Industries are challenging and Intelliject challenged two patents, which expire in 2025, covering the next generation autoinjector for use with epinephrine that is sold under the EpiPen brand name. In February 2012, the action against Intelliject was settled. Under the settlement agreement, Intellject may launch its epinephrine injectable product no earlier than November 15, 2012, subject to final approval by the FDA.

Embeda (morphine sulfate/naltrexone hydrochloride extended-release capsules)

In August 2011, Watson Laboratories Inc. – Florida (Watson Florida) notified us that it had filed an abbreviated new drug application with the FDA seeking approval to market a generic version of Embeda extended-release capsules. Watson Florida asserts the invalidity and non-infringement of three formulation patents that expire in 2027. In October 2011, we filed an action against Watson Florida in the U.S. District Court for the District of Delaware asserting the infringement of, and defending against the allegations of the invalidity of, the three formulation patents.

Torisel (temsirolimus)

In November 2011, Sandoz and Accord Healthcare, Inc. USA and certain of its affiliates (collectively, Accord) notified us that they had filed abbreviated new drug applications with the FDA seeking approval to market generic versions of Torisel. Sandoz and Accord assert the invalidity and non-infringement of two patents for Torisel, including the basic patent, which expires in 2014. In December 2011, we filed suit against Sandoz and Accord in the U.S. District Court for the District of Delaware asserting the infringement of, and defending against the allegation of the invalidity of, the basic patent.

ACTION IN WHICH WE ARE THE DEFENDANT AND A RELATED ACTION

ReFacto AF and Xyntha

In February 2008, Novartis Vaccines and Diagnostics, Inc. (Novartis) filed suit against Wyeth and a subsidiary of Wyeth in the U.S. District Court for the Eastern District of Texas alleging that Wyeth’s ReFacto AF and Xyntha products infringe two Novartis patents. Novartis’s complaint seeks damages, including treble damages, for alleged willful infringement. Wyeth and its subsidiary assert, among other things, the invalidity and non-infringement of the Novartis patents. In November 2009, Novartis added a third patent to its infringement claim against Wyeth and its subsidiary. In August 2010, Novartis granted Wyeth and its subsidiary a covenant not to sue on the third patent and withdrew that patent from its pending action.

In May 2008, a subsidiary of Wyeth filed suit in the U.S. District Court for the District of Delaware against Novartis seeking a declaration that the two Novartis patents initially asserted against Wyeth and its subsidiary in the action referred to in the preceding paragraph are invalid on the ground that the Wyeth subsidiary was the first to invent the subject matter. In February 2010, the District of Delaware declined to invalidate those two Novartis patents. In March 2010, the Wyeth subsidiary appealed the decision to the U.S. Court of Appeals for the Federal Circuit. In August 2011, the Federal Circuit affirmed the District Court’s decision. In November 2011, the Federal Circuit denied the Wyeth subsidiary’s petition for a rehearing. The Federal Circuit’s decision does not address the defenses that Wyeth and its subsidiary are asserting in the action referred to in the previous paragraph.

B. Product Litigation

Like other pharmaceutical companies, we are defendants in numerous cases, including but not limited to those discussed below, related to our pharmaceutical and other products. Plaintiffs in these cases seek damages and other relief on various grounds for alleged personal injury and economic loss.

Asbestos

•   Quigley

Quigley Company, Inc. (Quigley), a wholly owned subsidiary, was acquired by Pfizer in 1968 and sold products containing small amounts of asbestos until the early 1970s. In September 2004, Pfizer and Quigley took steps that were intended to resolve all pending and future claims against Pfizer and Quigley in which the claimants allege personal injury from exposure to Quigley products containing asbestos, silica or mixed dust. We recorded a charge of $369 million pre-tax ($229 million after-tax) in the third quarter of 2004 in connection with these matters.

In September 2004, Quigley filed a petition in the U.S. Bankruptcy Court for the Southern District of New York seeking reorganization under Chapter 11 of the U.S. Bankruptcy Code. In March 2005, Quigley filed a reorganization plan in the Bankruptcy Court that needed the approval of 75% of the voting claimants, as well as the Bankruptcy Court and the U.S. District Court for the Southern District of New York. In connection with that filing, Pfizer entered into settlement agreements with lawyers representing more than 80% of the individuals with claims related to Quigley products against Quigley and Pfizer. The agreements provide for a total of $430 million in payments, of which $215 million became due in December 2005 and has been and is being paid to claimants upon receipt by the Company of certain required documentation from each of the claimants. The reorganization plan provided for the establishment of a Trust (the Trust) for the evaluation and, as appropriate, payment of all unsettled pending claims, as well as any future claims alleging injury from exposure to Quigley products.

In February 2008, the Bankruptcy Court authorized Quigley to solicit an amended reorganization plan for acceptance by claimants. According to the official report filed with the court by the balloting agent in July 2008, the requisite votes were cast in favor of the amended plan of reorganization.

The Bankruptcy Court held a confirmation hearing with respect to Quigley’s amended plan of reorganization that concluded in December 2009. In September 2010, the Bankruptcy Court declined to confirm the amended reorganization plan. As a result of the foregoing, Pfizer recorded additional charges for this matter of approximately $1.3 billion pre-tax (approximately $800 million after-tax) in 2010. Further, in order to preserve its right to address certain legal issues raised in the court’s opinion, in October 2010, Pfizer filed a notice of appeal and motion for leave to appeal the Bankruptcy Court’s decision denying confirmation.

In March 2011, Pfizer entered into a settlement agreement with a committee (the Ad Hoc Committee) representing approximately 40,000 claimants in the Quigley bankruptcy proceeding (the Ad Hoc Committee claimants). Consistent with the additional charges recorded in 2010 referred to above, the principal provisions of the settlement agreement provide for a settlement payment in two installments and other consideration, as follows:

•    the payment to the Ad Hoc Committee, for the benefit of the Ad Hoc Committee claimants, of a first installment of $500 million upon receipt by Pfizer of releases of asbestos-related claims against Pfizer Inc. from Ad Hoc Committee claimants holding $500 million in the aggregate of claims (Pfizer began paying this first installment in June 2011);

•    the payment to the Ad Hoc Committee, for the benefit of the Ad Hoc Committee claimants, of a second installment of $300 million upon Pfizer’s receipt of releases of asbestos-related claims against Pfizer Inc. from Ad Hoc Committee claimants holding an additional $300 million in the aggregate of claims following the earlier of the effective date of a revised plan of reorganization and April 6, 2013;

•    the payment of the Ad Hoc Committee’s legal fees and expenses incurred in this matter up to a maximum of $19 million (Pfizer began paying these legal fees and expenses in May 2011); and

•    the procurement by Pfizer of insurance for the benefit of certain Ad Hoc Committee claimants to the extent such claimants with non-malignant diseases have a future disease progression to a malignant disease (Pfizer procured this insurance in August 2011).

Following the execution of the settlement agreement with the Ad Hoc Committee, Quigley filed a revised plan of reorganization and accompanying disclosure statement with the Bankruptcy Court in April 2011. Under the revised plan, and consistent with the additional charges recorded in 2010 referred to above, we expect to contribute an additional amount to the Trust, if and when the Bankruptcy Court confirms the plan, of cash and non-cash assets (including insurance proceeds) with a value in excess of $550 million. The Bankruptcy Court must find that the revised plan meets the requisite standards of the U.S. Bankruptcy Code before it confirms the plan. We expect that, if approved by claimants, confirmed by the Bankruptcy Court and the District Court and upheld on any subsequent appeal, the revised reorganization plan will result in the District Court entering a permanent injunction directing pending claims, as well as future claims, alleging personal injury from exposure to Quigley products to the Trust. There is no assurance that the plan will be confirmed by the courts.

In a separately negotiated transaction with an insurance company in August 2004, we agreed to a settlement related to certain insurance coverage which provides for payments to an insurance proceeds trust established by Pfizer and Quigley over a ten-year period of amounts totaling $405 million. Most of these insurance proceeds, as well as other payments from insurers that issued policies covering Pfizer and Quigley, would be paid, following confirmation, to the Trust for the benefit of present unsettled and future claimants with claims arising from exposure to Quigley products.

•   Other Matters

Between 1967 and 1982, Warner-Lambert owned American Optical Corporation, which manufactured and sold respiratory protective devices and asbestos safety clothing. In connection with the sale of American Optical in 1982, Warner-Lambert agreed to indemnify the purchaser for certain liabilities, including certain asbestos-related and other claims. As of December 31, 2011, approximately 67,700 claims naming American Optical and numerous other defendants were pending in various federal and state courts seeking damages for alleged personal injury from exposure to asbestos and other allegedly hazardous materials. Warner-Lambert is actively engaged in the defense of, and will continue to explore various means to resolve, these claims.

Warner-Lambert and American Optical brought suit in state court in New Jersey against the insurance carriers that provided coverage for the asbestos and other allegedly hazardous materials claims related to American Optical. A majority of the carriers subsequently agreed to pay for a portion of the costs of defending and resolving those claims. The litigation continues against the carriers who have disputed coverage or how costs should be allocated to their policies, and the court held that Warner-Lambert and American Optical are entitled to payment from each of those carriers of a proportionate share of the costs associated with those claims. Under New Jersey law, a special allocation master was appointed to implement certain aspects of the court’s rulings.

Numerous lawsuits are pending against Pfizer in various federal and state courts seeking damages for alleged personal injury from exposure to products containing asbestos and other allegedly hazardous materials sold by Gibsonburg Lime Products Company (Gibsonburg). Gibsonburg was acquired by Pfizer in the 1960s and sold products containing small amounts of asbestos until the early 1970s.

There also is a small number of lawsuits pending in various federal and state courts seeking damages for alleged exposure to asbestos in facilities owned or formerly owned by Pfizer or its subsidiaries.

Celebrex and Bextra

•   Securities and ERISA Actions

Beginning in late 2004, actions, including purported class actions, were filed in various federal and state courts against Pfizer, Pharmacia Corporation (Pharmacia) and certain current and former officers, directors and employees of Pfizer and Pharmacia. These actions include (i) purported class actions alleging that Pfizer and certain current and former officers of Pfizer violated federal securities laws by misrepresenting the safety of Celebrex and Bextra, and (ii) purported class actions filed by persons who claim to be participants in the Pfizer or Pharmacia Savings Plan alleging that Pfizer and certain current and former officers, directors and employees of Pfizer or, where applicable, Pharmacia and certain former officers, directors and employees of Pharmacia, violated certain provisions of the Employee Retirement Income Security Act of 1974 (ERISA) by selecting and maintaining Pfizer stock or Pharmacia stock as an investment alternative when it allegedly no longer was a suitable or prudent investment option. In June 2005, the federal securities and ERISA actions were transferred for consolidated pre-trial proceedings to a Multi-District Litigation (In re Pfizer Inc. Securities, Derivative and “ERISA” Litigation MDL-1688) in the U.S. District Court for the Southern District of New York.

•   Securities Action in New Jersey

In 2003, several purported class action complaints were filed in the U.S. District Court for the District of New Jersey against Pharmacia, Pfizer and certain former officers of Pharmacia. The plaintiffs seek damages, alleging that the defendants violated federal securities laws by misrepresenting the data from a study concerning the gastrointestinal effects of Celebrex. These cases were consolidated for pre-trial proceedings in the District of New Jersey (Alaska Electrical Pension Fund et al. v. Pharmacia Corporation et al.). In January 2007, the court certified a class consisting of all persons who purchased Pharmacia securities from April 17, 2000 through February 6, 2001 and were damaged as a result of the decline in the price of Pharmacia’s securities allegedly attributable to the misrepresentations.

In October 2007, the court granted defendants’ motion for summary judgment and dismissed the plaintiffs’ claims. In November 2007, the plaintiffs appealed the decision to the U.S. Court of Appeals for the Third Circuit. In January 2009, the Third Circuit vacated the District Court’s grant of summary judgment in favor of defendants and remanded the case to the District Court for further proceedings. The Third Circuit also held that the District Court erred in determining that the class period ended on February 6, 2001, and directed that the class period end on August 5, 2001. In June 2009, the District Court stayed proceedings in the case pending a determination by the U.S. Supreme Court with regard to defendants’ petition for certiorari seeking reversal of the Third Circuit’s decision. In May 2010, the U.S. Supreme Court denied defendants’ petition for certiorari, and the case was remanded to the District Court for further proceedings.

Pfizer and several predecessor and affiliated companies, including Monsanto Company (Monsanto), are defendants in an action brought by Brigham Young University (BYU) and a BYU professor in the U.S. District Court for the District of Utah alleging, among other things, breach by Monsanto of a 1991 research agreement with BYU. Plaintiffs claim that research under that agreement led to the discovery of Celebrex and that, as a result, they are entitled to a share of the profits from Celebrex sales. Plaintiffs seek, among other things, compensatory and punitive damages.

Various Drugs: Off-Label Promotion Actions

•   Securities Action

In May 2010, a purported class action was filed in the U.S. District Court for the Southern District of New York against Pfizer and several of our current and former officers. The complaint alleges that the defendants violated federal securities laws by failing to disclose that Pfizer was engaged in off-label marketing of certain drugs. Plaintiffs seek damages in an unspecified amount.

•   Actions by Health Care Service Corporation

In June 2010, Health Care Service Corporation (HCSC), for itself and its affiliates, Blue Cross and Blue Shield plans in Illinois, New Mexico, Oklahoma and Texas, filed an action against us in the U.S. District Court for the Eastern District of Texas. In July 2010, HCSC amended its complaint. The complaint, as amended, alleges that we engaged in deceptive marketing activities, including off-label promotion, and the payment of improper remuneration to healthcare professionals with respect to Bextra and Celebrex in violation of, among other things, the federal Racketeer Influenced and Corrupt Organizations (RICO) Act and the Illinois Consumer Fraud Act. In December 2010, this action was transferred to a Multi-District Litigation (In re Celebrex and Bextra Marketing, Sales Practices and Product Liability Litigation MDL-1699) in the U.S. District Court for the Northern District of California. In July 2010, HCSC also filed a separate lawsuit against us in the U.S. District Court for the Eastern District of Texas including substantially similar allegations regarding Geodon, Lyrica and Zyvox. In this latter action, in October 2011, HCSC filed an amended complaint that is substantially similar to the original complaint except that it no longer includes allegations regarding Lyrica or claims under the Illinois Consumer Fraud Act. In both actions, HCSC seeks to recover the amounts that it paid for the specified drugs on behalf of its members in Illinois, New Mexico, Oklahoma, and Texas, as well as treble damages and punitive damages.

Hormone-Replacement Therapy

•    Personal Injury and Economic Loss Actions

Pfizer and certain wholly owned subsidiaries and limited liability companies, including Wyeth and King, along with several other pharmaceutical manufacturers, have been named as defendants in approximately 10,000 actions in various federal and state courts alleging personal injury or economic loss related to the use or purchase of certain estrogen and progestin medications prescribed for women to treat the symptoms of menopause. Although new actions are occasionally filed, the number of new actions was not significant in 2011, and we do not expect a substantial change in the rate of new actions being filed. Plaintiffs in these suits allege a variety of personal injuries, including breast cancer, ovarian cancer, stroke and heart disease. Certain co-defendants in some of these actions have asserted indemnification rights against Pfizer and its affiliated companies. The cases against Pfizer and its affiliated companies involve one or more of the following products, all of which remain approved by the FDA: femhrt (which Pfizer divested in 2003); Activella and Vagifem (which are Novo Nordisk products that were marketed by a Pfizer affiliate from 2000 to 2004); Premarin, Prempro, Aygestin, Cycrin and Premphase (which are legacy Wyeth products); and Provera, Ogen, Depo-Estradiol, Estring and generic MPA (which are legacy Pharmacia & Upjohn products). The federal cases have been transferred for consolidated pre-trial proceedings to a Multi-District Litigation (In re Prempro Products Liability Litigation MDL-1507) in the U.S. District Court for the Eastern District of Arkansas. Certain of the federal cases have been remanded to their respective District Courts for further proceedings including, if necessary, trial.

This litigation consists of individual actions, a few purported statewide class actions and a purported provincewide class action in Quebec, Canada, a statewide class action in California and a nationwide class action in Canada. In March 2011, in an action against Wyeth seeking the refund of the purchase price paid for Wyeth’s hormone-replacement therapy products by individuals in the State of California during the period from January 1995 to January 2003, the U.S. District Court for the Southern District of California certified a class consisting of all individual purchasers of such products in California who actually heard or read Wyeth’s alleged misrepresentations regarding such products. This is the only hormone-replacement therapy action to date against Pfizer and its affiliated companies in the U.S. in which a class has been certified. In addition, in August 2011, in an action against Wyeth seeking damages for personal injury, the Supreme Court of British Columbia certified a class consisting of all women who were prescribed Premplus and/or Premarin in combination with progestin in Canada between January 1, 1997 and December 1, 2003 and who thereafter were diagnosed with breast cancer.

Pfizer and its affiliated companies have prevailed in many of the hormone-replacement therapy actions that have been resolved to date, whether by voluntary dismissal by the plaintiffs, summary judgment, defense verdict or judgment notwithstanding the verdict; a number of these cases have been appealed by the plaintiffs. Certain other hormone-replacement therapy actions have resulted in verdicts for the plaintiffs and have included the award of compensatory and, in some instances, punitive damages; each of these cases has been appealed by Pfizer and/or its affiliated companies. The decisions in a few of the cases that had been appealed by Pfizer and/or its affiliated companies or by the plaintiffs have been upheld by the appellate courts, while several other cases that had been appealed by Pfizer and/or its affiliated companies or by the plaintiffs have been remanded by the appellate courts to their respective trial courts for further proceedings. Trials of additional hormone-replacement therapy actions are underway or scheduled in 2012.

As of December 31, 2011, Pfizer and its affiliated companies had settled, or entered into definitive agreements or agreements-in-principle to settle, approximately 52% of the hormone-replacement therapy actions pending against us and our affiliated companies. We have recorded aggregate charges with respect to those actions, as well as with respect to the actions that have resulted in verdicts against us or our affiliated companies, of $336 million in 2011 and $300 million in prior years. In addition, we have recorded a charge of $359 million in 2011 that provides for the minimum expected costs to resolve all remaining hormone-replacement therapy actions against Pfizer and its affiliated companies, consistent with our current ability to quantify such future costs. The $359 million charge is an estimate and, while we cannot reasonably estimate the range of reasonably possible loss in excess of the amount accrued for these contingencies given the uncertainties inherent in this product liability litigation, as described below, additional charges may be required in the future.

Most of the unresolved actions against Pfizer and/or its affiliated companies have been outstanding for more than five years and could take many more years to resolve. However, opportunistic settlements could occur at any time. The litigation process is time-consuming, as every hormone-replacement action being litigated involves contested issues of medical causation and knowledge of risk. Even though the vast majority of hormone-replacement therapy actions concern breast cancer, the underlying facts (e.g., medical causation, family history, reliance on warnings, physician/patient interaction, analysis of labels, actual provable injury and other critical factors) can differ significantly from action to action, and the process of discovery has not yet begun for a majority of the unresolved actions. Our ability to estimate the range of possible loss in excess of amounts accrued is complicated by these factors. In addition, the hormone-replacement therapy litigation involves fundamental issues of science and medicine that often are uncertain and continue to evolve. Key scientific court rulings may have a significant impact on the litigation as a whole. An integral part of the litigation process involves understanding the evolving science, as well as seeking key scientific rulings. Equally important, the discovery process is lengthy and complex and has not yet begun for a majority of the unresolved actions. Therefore, we may not have sufficient information to determine the percentage of unresolved actions that could be impacted by scientific developments and/or key scientific rulings. Our ability to estimate the range of possible loss in excess of amounts accrued is complicated by these fundamental issues of science and medicine, because we do not know how the science may evolve, how the courts will rule on key motions or which unresolved actions will be impacted by these scientific matters.

Accordingly, we cannot reasonably estimate the range of possible loss in excess of amounts accrued for these contingencies.

•    Government Inquiries; Action by State of Nevada

Pfizer and/or its affiliated companies also have received inquiries from various federal and state agencies and officials relating to the marketing of their hormone-replacement products. In November 2008, the State of Nevada filed an action against Pfizer, Pharmacia & Upjohn Company and Wyeth in state court in Nevada alleging that they had engaged in deceptive marketing of their respective hormone-replacement therapy medications in Nevada in violation of the Nevada Deceptive Trade Practices Act. The action seeks monetary relief, including civil penalties and treble damages. In February 2010, the action was dismissed by the court on the grounds that the statute of limitations had expired. In July 2011, the Nevada Supreme Court reversed the dismissal and remanded the case to the district court for further proceedings.

Zoloft and Effexor

•    Personal Injury Actions

A number of individual lawsuits and multi-plaintiff lawsuits have been filed against us and/or our subsidiaries in various federal and state courts alleging personal injury as a result of the purported ingesting of Zoloft or Effexor.

•    Antitrust Actions

Beginning in May 2011, purported class actions were filed in certain federal courts against Wyeth and, in certain of the actions, affiliates of Wyeth and certain other defendants relating to Effexor XR, which is the extended-release formulation of Effexor. The plaintiffs in each of these actions seek to represent a class consisting of all persons in the U.S. and its territories who purchased Effexor XR or generic Effexor XR directly (in certain of the actions) or indirectly (in the other actions) from any of the defendants from June 14, 2008 until the time the defendants’ allegedly unlawful conduct ceased (the Class Period). The plaintiffs allege delay in the launch of generic Effexor XR in the U.S. and its territories, in violation of federal antitrust laws and, in the indirect-purchaser actions, the antitrust, consumer protection and various other laws of certain states, as the result of Wyeth fraudulently obtaining and improperly listing certain patents for Effexor XR, enforcing certain patents for Effexor XR, and entering into litigation settlement agreements with various generic manufacturers with respect to Effexor XR. Each of the actions seeks treble damages on behalf of the putative class for alleged price overcharges for Effexor XR or generic Effexor XR in the U.S. and its territories during the Class Period. All of the purported class actions brought by direct purchasers have been consolidated in the U.S. District Court for the District of New Jersey, and all of the purported class actions brought by indirect purchasers have been separately consolidated in the same court. In addition, a few individual actions are pending in the same court that assert claims and seek relief for the plaintiffs that are substantially similar to the claims asserted and the relief sought in the purported class actions.

Neurontin

•    Off-Label Promotion Actions in the U.S.

A number of lawsuits, including purported class actions, have been filed against us in various federal and state courts alleging claims arising from the promotion and sale of Neurontin. The plaintiffs in the purported class actions seek to represent nationwide and certain statewide classes consisting of persons, including individuals, health insurers, employee benefit plans and other third-party payers, who purchased or reimbursed patients for the purchase of Neurontin that allegedly was used for indications other than those included in the product labeling approved by the FDA. In 2004, many of the suits pending in federal courts, including individual actions as well as purported class actions, were transferred for consolidated pre-trial proceedings to a Multi-District Litigation (In re Neurontin Marketing, Sales Practices and Product Liability Litigation MDL-1629) in the U.S. District Court for the District of Massachusetts.

In the Multi-District Litigation, in 2009, the court denied the plaintiffs’ renewed motion for certification of a nationwide class of all consumers and third-party payers who allegedly purchased or reimbursed patients for the purchase of Neurontin for off-label uses from 1994 through 2004. In May 2011, the court denied a motion to reconsider its class certification ruling.

In 2010, the Multi-District Litigation court partially granted the Company’s motion for summary judgment, dismissing the claims of all of the proposed class representatives for third-party payers and four of the six proposed class representatives for individual consumers. In June 2011, the plaintiffs whose claims were dismissed appealed both the dismissal and the denial of class certification to the U.S. Court of Appeals for the First Circuit.

Also in the Multi-District Litigation, in February 2011, a third-party payer who was not included in the proposed class action appealed a dismissal order to the U.S. Court of Appeals for the First Circuit.

Plaintiffs are seeking certification of statewide classes of Neurontin purchasers in actions pending in California, Illinois and Oklahoma. State courts in New York, Pennsylvania, Missouri and New Mexico have declined to certify statewide classes of Neurontin purchasers. In November 2011, the plaintiff in the Missouri action and a proposed intervenor appealed the denial of class certification.

In January 2011, the U.S. District Court for the District of Massachusetts entered an order trebling a jury verdict against us in an action by a third-party payer seeking damages for the alleged off-label promotion of Neurontin in violation of the federal Racketeer Influenced and Corrupt Organizations (RICO) Act. The verdict was for $47.4 million, which was subject to automatic trebling to $142.1 million under the RICO Act. In November 2010, the court had entered a separate verdict against us in the amount of $65.4 million, together with prejudgment interest, under California’s Unfair Trade Practices law relating to the same alleged conduct, which amount is included within and is not additional to the $142.1 million trebled amount of the jury verdict. In August 2011, we appealed the District Court’s judgment to the U.S. Court of Appeals for the First Circuit.

•   Personal Injury Actions in the U.S. and Certain Other Countries

A number of individual lawsuits have been filed against us in various U.S. federal and state courts and in certain other countries alleging suicide, attempted suicide and other personal injuries as a result of the purported ingesting of Neurontin. Certain of the U.S. federal actions have been transferred for consolidated pre-trial proceedings to the same Multi-District Litigation referred to in the first paragraph of this section.

In addition, purported class actions have been filed against us in various Canadian provincial courts alleging claims arising from the promotion, sale and labeling of Neurontin and generic gabapentin. In a proceeding pending in Ontario, Canada, the court certified a class consisting of all persons in Canada who purchased and ingested Neurontin prior to August 2004. The plaintiffs claim that Pfizer failed to provide adequate warning of the alleged risks of personal injury associated with Neurontin.

•   Antitrust Action in the U.S.

In January 2011, in a Multi-District Litigation (In re Neurontin Antitrust Litigation MDL-1479) that consolidates four actions, the U.S. District Court for the District of New Jersey certified a nationwide class consisting of wholesalers and other entities who purchased Neurontin directly from Pfizer and Warner-Lambert during the period from December 11, 2002 to August 31, 2008 and who also purchased generic gabapentin after it became available. The complaints allege that Pfizer and Warner-Lambert engaged in anticompetitive conduct in violation of the Sherman Act that included, among other things, submitting patents for listing in the Orange Book and prosecuting and enforcing certain patents relating to Neurontin, as well as engaging in off-label marketing of Neurontin. Plaintiffs seek compensatory damages, which may be subject to trebling.

Lipitor

•   Whistleblower Action

In 2004, a former employee filed a “whistleblower” action against us in the U.S. District Court for the Eastern District of New York. The complaint remained under seal until September 2007, at which time the U.S. Attorney for the Eastern District of New York declined to intervene in the case. We were served with the complaint in December 2007. Plaintiff alleges off-label promotion of Lipitor in violation of the Federal Civil False Claims Act and the false claims acts of certain states, and he seeks treble damages and civil penalties on behalf of the federal government and the specified states as the result of their purchase, or reimbursement of patients for the purchase, of Lipitor allegedly for such off-label uses. Plaintiff also seeks compensation as a whistleblower under those federal and state statutes. In addition, plaintiff alleges that he was wrongfully terminated, in violation of the anti-retaliation provisions of applicable federal and New York law, and he seeks damages and the reinstatement of his employment. In 2009, the court dismissed without prejudice the off-label promotion claims and, in 2010, plaintiff filed an amended complaint containing off-label promotion allegations that are substantially similar to the allegations in the original complaint.

•   Antitrust Actions

Beginning in November 2011, purported class actions relating to Lipitor were filed in various federal and state courts against Pfizer, certain affiliates of Pfizer, and, in most of the actions, Ranbaxy, among others. The plaintiffs seek to represent nationwide or statewide classes consisting of persons or entities who directly purchased, indirectly purchased or reimbursed patients for the purchase of Lipitor (or, in certain of the actions, generic Lipitor) from any of the defendants from March 2010 until the cessation of the defendants’ allegedly unlawful conduct (the Class Period). The plaintiffs allege delay in the launch of generic Lipitor, in violation of federal antitrust laws and/or state antitrust, consumer protection and various other laws resulting from (i) the 2008 agreement pursuant to which Pfizer and Ranbaxy settled certain patent litigation involving Lipitor, and Pfizer granted Ranbaxy a license to sell a generic version of Lipitor in various markets beginning on varying dates, and (ii) in certain of the federal actions, the procurement and/or enforcement of certain patents for Lipitor. Each of the actions seeks, among other things, treble damages on behalf of the putative class for alleged price overcharges for Lipitor (or, in certain of the actions, generic Lipitor) during the Class Period. In addition, an individual action by several California pharmacies was filed in January 2012 in state court in California against Pfizer, Ranbaxy and certain of their affiliates, among others, that asserts claims and seeks relief for the plaintiff pharmacies that are substantially similar to the claims asserted and the relief sought in the purported class actions described above.

Chantix/Champix

A number of individual lawsuits have been filed against us in various federal and state courts alleging suicide, attempted suicide and other personal injuries as a result of the purported ingesting of Chantix, as well as economic loss. Plaintiffs in these actions seek compensatory and punitive damages and the disgorgement of profits resulting from the sale of Chantix. In October 2009, the federal cases were transferred for consolidated pre-trial proceedings to a Multi-District Litigation (In re Chantix (Varenicline) Products Liability Litigation MDL-2092) in the U.S. District Court for the Northern District of Alabama.

Beginning in December 2008, purported class actions were filed against us in the Ontario Superior Court of Justice (Toronto Region), the Superior Court of Quebec (District of Montreal), the Court of Queen’s Bench of Alberta, Judicial District of Calgary, and the Superior Court of British Columbia (Vancouver Registry) on behalf of all individuals and third-party payers in Canada who have purchased and ingested Champix or reimbursed patients for the purchase of Champix. Each of these actions asserts claims under Canadian product liability law, including with respect to the safety and efficacy of Champix, and, on behalf of the putative class, seeks monetary relief, including punitive damages. The actions in Quebec, Alberta and British Columbia have been stayed pending the decision regarding class certification in the Ontario action.

Bapineuzumab

In June 2010, a purported class action was filed in the U.S. District Court for the District of New Jersey against Pfizer, as successor to Wyeth, and several former officers of Wyeth. The complaint alleges that Wyeth and the individual defendants violated federal securities laws by making or causing Wyeth to make false and misleading statements, and by failing to disclose or causing Wyeth to fail to disclose material information, concerning the results of a clinical trial involving bapineuzumab, a product in development for the treatment of Alzheimer’s disease. The plaintiff seeks to represent a class consisting of all persons who purchased Wyeth securities from May 21, 2007 through July 2008 and seeks damages in an unspecified amount on behalf of the putative class. In February 2012, the court granted the defendants’ motion to dismiss the complaint. The court’s decision is subject to possible appeal by the plaintiff.

In July 2010, a related action was filed in the U.S. District Court for the Southern District of New York against Elan Corporation (Elan), certain directors and officers of Elan, and Pfizer, as successor to Wyeth. Elan participated in the development of bapineuzumab until September 2009. The complaint alleges that Elan, Wyeth and the individual defendants violated federal securities laws by making or causing Elan to make false and misleading statements, and by failing to disclose or causing Elan to fail to disclose material information, concerning the results of a clinical trial involving bapineuzumab. The plaintiff seeks to represent a class consisting of all persons who purchased Elan call options from June 17, 2008 through July 29, 2008 and seeks damages in an unspecified amount on behalf of the putative class. In June 2011, the court granted Pfizer’s and Elan’s motions to dismiss the complaint. In July 2011, the plaintiff filed a supplemental memorandum setting forth the bases that the plaintiff believed supported amendment of the complaint. In August 2011, the court dismissed the complaint with prejudice. In September 2011, the plaintiff appealed the District Court’s decision to the U.S. Court of Appeals for the Second Circuit.

Thimerosal

Wyeth is a defendant in a number of suits by or on behalf of vaccine recipients alleging that exposure through vaccines to cumulative doses of thimerosal, a preservative used in certain childhood vaccines formerly manufactured and distributed by Wyeth and other vaccine manufacturers, caused severe neurological damage and/or autism in children. While several suits were filed as purported nationwide or statewide class actions, all of the purported class actions have been dismissed, either by the courts or voluntarily by the plaintiffs. In addition to the suits alleging injury from exposure to thimerosal, certain of the cases were brought by parents in their individual capacities for, among other things, loss of services and loss of consortium of the injured child.

The National Childhood Vaccine Injury Act (the Vaccine Act) requires that persons alleging injury from childhood vaccines first file a petition in the U.S. Court of Federal Claims asserting a vaccine-related injury. At the conclusion of that proceeding, petitioners may bring a lawsuit against the manufacturer in federal or state court, provided that they have satisfied certain procedural requirements. Also under the terms of the Vaccine Act, if a petition has not been adjudicated by the U.S. Court of Federal Claims within a specified time period after filing, the petitioner may opt out of the proceeding and pursue a lawsuit against the manufacturer by following certain procedures. Some of the vaccine recipients who have sued Wyeth to date may not have satisfied the conditions to filing a lawsuit that are mandated by the Vaccine Act. The claims brought by parents for, among other things, loss of services and loss of consortium of the injured child are not covered by the Vaccine Act.

In 2002, the Office of Special Masters of the U.S. Court of Federal Claims established an Omnibus Autism Proceeding with jurisdiction over petitions in which vaccine recipients claim to suffer from autism or autism spectrum disorder as a result of receiving thimerosal-containing childhood vaccines and/or the measles, mumps and rubella (MMR) vaccine. There currently are several thousand petitions pending in the Omnibus Autism Proceeding. Special masters of the court have heard six test cases on petitioners’ theories that either thimerosal-containing vaccines in combination with the MMR vaccine or thimerosal-containing vaccines alone can cause autism or autism spectrum disorder.

•    In February 2009, special masters of the U.S. Court of Federal Claims rejected the three cases brought on the theory that a combination of MMR and thimerosal-containing vaccines caused petitioners’ conditions. After these rulings were affirmed by the U.S. Court of Federal Claims, two of them were appealed by petitioners to the U.S. Court of Appeals for the Federal Circuit. In 2010, the Federal Circuit affirmed the decisions of the special masters in both of these cases.

•    In March 2010, special masters of the U.S. Court of Federal Claims rejected the three additional test cases brought on the theory that thimerosal-containing vaccines alone caused petitioners’ conditions. Petitioners did not seek review by the U.S. Court of Federal Claims of the decisions of the special masters in these latter three test cases, and judgments were entered dismissing the cases in April 2010.

•    Petitioners in each of the six test cases have filed an election to bring a civil action.

Pristiq

In late 2007 and early 2008, the following actions were filed in various federal courts: (i) a purported class action alleging that Wyeth and certain former officers of Wyeth violated federal securities laws by misrepresenting the safety of Pristiq during the period before the FDA’s issuance in July 2007 of an “approvable letter” for Pristiq for the treatment of vasomotor symptoms, which allegedly caused a decline in the price of Wyeth stock; and (ii) a purported class action against Wyeth, the Wyeth Savings Plan Committee, the Wyeth Savings Plan-Puerto Rico Committee, the Wyeth Retirement Committee and certain former Wyeth officers and committee members alleging that they violated certain provisions of ERISA by maintaining Wyeth stock as an investment alternative under certain Wyeth plans notwithstanding their alleged knowledge of the aforementioned alleged misrepresentation.

The U.S. District Court for the Southern District of New York dismissed the ERISA action and denied the plaintiff’s motion to amend the complaint in March and August 2010, respectively. In September 2010, the plaintiff appealed both of those rulings to the U.S. Court of Appeals for the Second Circuit. In November 2010, the plaintiff withdrew the appeal, but has reserved the right to reinstate the appeal by March 2012. The purported securities class action remains pending.

Rebif

We have an exclusive collaboration agreement with EMD Serono, Inc. (Serono) to co-promote Rebif, a treatment for multiple sclerosis, in the U.S. In August 2011, Serono filed a complaint in the Philadelphia Court of Common Pleas seeking a declaratory judgment that we are not entitled to a 24-month extension of the Rebif co-promotion agreement, which otherwise would terminate at the end of 2013. We disagree with Serono’s interpretation of the agreement and believe that we have the right to extend the agreement to the end of 2015. In October 2011, the court sustained our preliminary objections and dismissed Serono’s complaint, and Serono has appealed the decision to the Superior Court of Pennsylvania.

C.  Commercial and Other Matters

Acquisition of Wyeth

In 2009, a number of retail pharmacies in California brought an action against Pfizer and Wyeth in the U.S. District Court for the Northern District of California. The plaintiffs alleged, among other things, that our acquisition of Wyeth violated various federal antitrust laws by creating a monopoly in the manufacture, distribution and sale of prescription drugs in the U.S. In April 2010, the District Court granted our motion to dismiss the second amended complaint. In May 2011, the U.S. Court of Appeals for the Ninth Circuit affirmed the dismissal by the District Court and, in June 2011, it denied plaintiffs’ petition for a rehearing. In December 2011, the U.S. Supreme Court denied the plaintiffs’ petition for certiorari seeking reversal of the Ninth Circuit’s decision.

Acquisition of King Pharmaceuticals, Inc.

In October 2010, several purported class action complaints were filed in state court in Tennessee by shareholders of King challenging Pfizer’s acquisition of King. King and the individuals who served as the members of King’s Board of Directors at the time of the execution of the merger agreement are named as defendants in all of these actions. Pfizer and Parker Tennessee Corp., a subsidiary of Pfizer, also are named as defendants in most of these actions.

In November 2010, all of these actions were consolidated in the Chancery Court for Sullivan County, Tennessee Second Judicial District, at Bristol. The parties to the consolidated action have reached an agreement-in-principle to resolve that action as a result of certain disclosures regarding the transaction made by King in its amended Schedule 14D-9 recommendation statement for the tender offer dated January 21, 2011. The proposed settlement is subject to, among other things, court approval.

Average Wholesale Price Litigation

A number of states, as well as most counties in New York, have sued Pharmacia, Pfizer and other pharmaceutical manufacturers alleging that they provided average wholesale price (AWP) information for certain of their products that was higher than the actual prices at which those products were sold. The AWP is used to determine reimbursement levels under Medicare Part B and Medicaid and in many private-sector insurance policies and medical plans. The plaintiffs claim that the alleged spread between the AWPs at which purchasers were reimbursed and the actual sale prices was promoted by the defendants as an incentive to purchase certain of their products. In addition to suing on their own behalf, many of the plaintiff states seek to recover on behalf of individual Medicare Part B co-payers and private-sector insurance companies and medical plans in their states. These various actions generally assert fraud claims, as well as claims under state deceptive trade practice laws, and seek monetary and other relief, including civil penalties and treble damages. Several of the suits also allege that Pharmacia and/or Pfizer did not report to the states their best price for certain products under the Medicaid program.

In addition, Pharmacia, Pfizer and other pharmaceutical manufacturers are defendants in a number of purported class action suits in various federal and state courts brought by employee benefit plans and other third-party payers that assert claims similar to those in the state and county actions. These suits allege, among other things, fraud, unfair competition and unfair trade practices and seek monetary and other relief, including civil penalties and treble damages.

All of these state, county and purported class action suits were transferred for consolidated pre-trial proceedings to a Multi-District Litigation (In re Pharmaceutical Industry Average Wholesale Price Litigation MDL-1456) in the U.S. District Court for the District of Massachusetts. Certain of the state and private suits have been remanded to their respective state courts. In 2006, the claims against Pfizer in the Multi-District Litigation were dismissed with prejudice.

In 2008, the court in the Multi-District Litigation granted preliminary approval with respect to the fairness of a proposed settlement of the claims against 11 defendants, including Pharmacia, for a total of $125 million. In December 2011, the court granted final approval of the settlement. Pharmacia’s contribution to the settlement was not material to Pfizer.

In addition, Wyeth is a defendant in AWP actions brought by certain states, which are not included in the Multi-District Litigation. Wyeth also is a defendant in a purported class action in state court in New Jersey brought by a union health and welfare plan on behalf of a putative class consisting of third-party payers in New Jersey. In addition, King and/or certain of its subsidiaries are defendants in AWP actions brought by certain states, which are not included in the Multi-District Litigation.

Monsanto-Related Matters

In 1997, Monsanto Company (Former Monsanto) contributed certain chemical manufacturing operations and facilities to a newly formed corporation, Solutia Inc. (Solutia), and spun off the shares of Solutia. In 2000, Former Monsanto merged with Pharmacia & Upjohn Company to form Pharmacia Corporation (Pharmacia). Pharmacia then transferred its agricultural operations to a newly created subsidiary, named Monsanto Company (New Monsanto), which it spun off in a two-stage process that was completed in 2002. Pharmacia was acquired by Pfizer in 2003 and is now a wholly owned subsidiary of Pfizer.

In connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities related to Pharmacia’s former agricultural business. New Monsanto is defending and indemnifying Pharmacia in connection with various claims and litigation arising out of, or related to, the agricultural business.

In connection with its spin-off in 1997, Solutia assumed, and agreed to indemnify Pharmacia for, liabilities related to Former Monsanto’s chemical businesses. As the result of its reorganization under Chapter 11 of the U.S. Bankruptcy Code, Solutia’s indemnification obligations related to Former Monsanto’s chemical businesses are limited to sites that Solutia has owned or operated. In addition, in connection with its spinoff that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities primarily related to Former Monsanto’s chemical businesses, including, but not limited to, any such liabilities that Solutia assumed. Solutia’s and New Monsanto’s assumption of and agreement to indemnify Pharmacia for these liabilities apply to pending actions and any future actions related to Former Monsanto’s chemical businesses in which Pharmacia is named as a defendant, including, without limitation, actions asserting environmental claims, including alleged exposure to polychlorinated biphenyls. Solutia and New Monsanto are defending and indemnifying Pharmacia in connection with various claims and litigation arising out of, or related to, Former Monsanto’s chemical businesses.

Trade Secrets Action in California

In 2004, Ischemia Research and Education Foundation (IREF) and its chief executive officer brought an action in California Superior Court, Santa Clara County, against a former IREF employee and Pfizer. Plaintiffs allege that defendants conspired to misappropriate certain information from IREF’s allegedly proprietary database in order to assist Pfizer in designing and executing a clinical study of a Pfizer drug. In 2008, the jury returned a verdict for compensatory damages of approximately $38.7 million. In March 2009, the court awarded prejudgment interest, but declined to award punitive damages. In July 2009, the court granted our motion for a new trial and vacated the jury verdict.

Trimegestone

Aventis filed a breach of contract action against Wyeth in the Commercial Court of Nanterre in France arising out of the December 2003 termination by Wyeth of an October 2000 agreement between Wyeth and Aventis relating to the development of hormone-therapy drugs utilizing Aventis’s trimegestone (TMG) progestin. Aventis alleges that the termination was improper and seeks monetary damages. In 2009, a three-judge tribunal rendered its decision in favor of Wyeth. In May 2010, the Versailles Court of Appeals reversed the Commercial Court’s decision and appointed experts to hear evidence and make a recommendation to the Court of Appeals concerning damages. In November 2011, the Supreme Court of France affirmed the decision of the Court of Appeals. The damage proceeding by the experts appointed by the Court of Appeals is continuing.

Environmental Matters

In 2009, we submitted to the U.S. Environmental Protection Agency (EPA) a corrective measures study report with regard to Pharmacia Corporation’s discontinued industrial chemical facility in North Haven, Connecticut and a revised site-wide feasibility study with regard to Wyeth’s discontinued industrial chemical facility in Bound Brook, New Jersey. In September 2010, our corrective measures study report with regard to the North Haven facility was approved by the EPA, and we commenced construction of the site remedy in late 2011 under an Updated Administrative Order on Consent with the EPA. In July 2011, we finalized an Administrative Settlement Agreement and Order on Consent for Removal Action with the EPA with regard to the Bound Brook facility and commenced construction of an interim remedy to address the discharge of impacted groundwater from that facility to the Raritan River. In February 2012, the EPA issued a proposed remediation plan for the Bound Brook facility. The proposed plan, which is subject to public comment, is generally in accordance with one of the remedies evaluated in the Company’s revised site-wide feasibility study. The estimated costs of the site remedy for the North Haven facility and the proposed remediation plan for the Bound Brook facility are covered by accruals previously taken by the Company.

We are a party to a number of other proceedings brought under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (CERCLA or Superfund), and other state, local or foreign laws in which the primary relief sought is the cost of past and/or future remediation.

In February 2011, King received notice from the U.S. Department of Justice (DOJ) advising that the EPA has requested that DOJ initiate enforcement action seeking injunctive relief and penalties against King for alleged non-compliance with certain provisions of the federal Clean Air Act at its Bristol, Tennessee manufacturing facility. King has executed a tolling agreement with the DOJ in order to facilitate the possible resolution of this matter.

In October 2011, we voluntarily disclosed to the EPA potential non-compliance with certain provisions of the federal Clean Air Act at our Barceloneta, Puerto Rico manufacturing facility. We do not expect that any penalties that may result from this matter will be material to the Company.

D. Government Investigations

Like other pharmaceutical companies, we are subject to extensive regulation by national, state and local government agencies in the U.S. and in the other countries in which we operate. As a result, we have interactions with government agencies on an ongoing basis. Among the investigations by government agencies are those discussed below. It is possible that criminal charges and substantial fines and/or civil penalties could result from government investigations, including but not limited to those discussed below.

The Company has voluntarily provided the DOJ and the U.S. Securities and Exchange Commission (SEC) with information concerning potentially improper payments made by certain Pfizer and Wyeth subsidiaries in connection with certain sales activities outside the U.S. In recent discussions, we have reached agreements-in-principle with the SEC staff and with the DOJ, and we are in the process of finalizing a resolution of these matters. In addition, certain potentially improper payments and other matters are the subject of investigations by government authorities in certain foreign countries. The previously reported investigation in Germany with respect to certain tax matters relating to a wholly owned subsidiary of Pfizer was resolved in December 2011 with no criminal charges and with the payment of an amount, primarily for interest, that was not material to Pfizer.

The DOJ is conducting civil and criminal investigations regarding Wyeth’s promotional practices with respect to Protonix and its practices relating to the pricing for Protonix for Medicaid rebate purposes. In connection with the pricing investigation, in 2009, the DOJ filed a civil complaint in intervention in two qui tam actions that had been filed under seal in the U.S. District Court for the District of Massachusetts. The complaint alleges that Wyeth’s practices relating to the pricing for Protonix for Medicaid rebate purposes between 2001 and 2006 violated the Federal Civil False Claims Act and federal common law. The two qui tam actions have been unsealed and the complaints include substantially similar allegations. In addition, in 2009, several states and the District of Columbia filed a complaint under the same docket number asserting violations of various state laws based on allegations substantially similar to those set forth in the civil complaint filed by the DOJ. We are exploring with the DOJ various ways to resolve its civil and criminal investigations relating to Protonix.

The DOJ, including the U.S. Attorney’s Office for the Western District of Oklahoma, is conducting a civil and criminal investigation with respect to Wyeth’s promotional practices relating to Rapamune. In addition, in October 2010, the DOJ was permitted to intervene in a qui tam action, which alleges off-label promotion of Rapamune, that was pending in the U.S. District Court for the Eastern District of Pennsylvania. In December 2010, the qui tam action was transferred to the Western District of Oklahoma, where it was consolidated with the proceedings underway there. We are exploring with the DOJ various ways to resolve this matter.

We have received civil investigative demands and informal inquiries from the consumer protection divisions of several states seeking information and documents concerning the promotion of Lyrica and Zyvox. We are in discussions with those states regarding a resolution of this matter. These requests appear to relate to the same past promotional practices concerning these products that were the subject of previously reported settlements in September 2009 with the DOJ and the Medicaid fraud control units of various states.

GUARANTEES AND INDEMNIFICATIONS

In the ordinary course of business and in connection with the sale of assets and businesses, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2011, recorded amounts for the estimated fair value of these indemnifications were not significant.

PURCHASE COMMITMENTS

As of December 31, 2011, we have agreements totaling $3.8 billion to purchase goods and services that are enforceable and legally binding and include amounts relating to advertising, information technology services, employee benefit administration services, and potential milestone payments deemed reasonably likely to occur.
