We review our interests in&nbsp;our investee companies for consolidation and/or appropriate disclosure based on applicable guidance. As disclosed in Note 1, we determined that certain of our investee companies are variable interest entities; however, other than with respect to our joint ventures with BMS, we are not the primary beneficiary and therefore do not consolidate these investees. </font></p> <p style="margin-top: 18px; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>Bristol-Myers Squibb Company </b></font></p> <p style="margin-top: 6px; margin-bottom: 0px; margin-left: 4%;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>North America </i></font></p> <p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In December 2004, we entered into a collaboration arrangement with BMS in the United States to develop and commercialize a single tablet regimen containing our Truvada and BMS's Sustiva (efavirenz), which we sell as Atripla. The collaboration is structured as a joint venture and operates as a limited liability company named Bristol-Myers Squibb&nbsp;&amp; Gilead Sciences, LLC, which we consolidate. The ownership interests of the joint venture and thus the sharing of product revenue and costs reflect the respective economic interests of BMS and Gilead and are based on the proportions of the net selling price of Atripla attributable to efavirenz and Truvada. Since the net selling price for Truvada may change over time relative to the net selling price of efavirenz, both BMS's and our respective economic interests in the joint venture may vary annually. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">We share marketing and sales efforts with BMS and both parties are obligated to provide equivalent sales force efforts for a minimum number of years. Starting in the second quarter of 2011, except for a limited number of activities that will be jointly managed, the parties will no longer coordinate detailing and promotional activities in the United States. The parties will continue to collaborate on activities such as manufacturing, regulatory, compliance and pharmacovigilance. We are responsible for accounting, financial reporting, tax reporting, manufacturing and product distribution for the joint venture. Both parties provide their respective bulk active pharmaceutical ingredients to the joint venture at their approximate market values. In July 2006, the joint venture received approval from the FDA to sell Atripla in the United States. In September&nbsp;2006, we and BMS amended the joint venture's collaboration agreement to allow the joint venture to sell Atripla into Canada and in October 2007, the joint venture received approval from Health Canada to sell Atripla in Canada. As December&nbsp;31, 2010 and 2009, the joint venture held efavirenz active pharmaceutical ingredient which it purchased from BMS at BMS's estimated net selling price of efavirenz in the U.S. market. These amounts are included in inventories on our Consolidated Balance Sheets. As of December&nbsp;31, 2010 and 2009, total assets held by the joint venture were $<font class="_mt">1.45</font> billion and $<font class="_mt">1.40</font> billion, respectively, and consisted primarily of cash and cash equivalents, accounts receivable (including intercompany receivables with Gilead) and inventories. As of December&nbsp;31, 2010 and 2009, total liabilities held by the joint venture were $<font class="_mt">759.5</font> million and $<font class="_mt">1.03</font> billion, respectively, and consisted primarily of accounts payable (including intercompany payables with Gilead) and other accrued expenses. These asset and liability amounts do not reflect the impact of intercompany eliminations that are included in our Consolidated Balance Sheets. Although we are the primary beneficiary of the joint venture, the legal structure of the joint venture limits the recourse that its creditors will have over our general credit or assets. </font></p> <p style="margin-top: 18px; margin-bottom: 0px; margin-left: 4%;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Europe </i></font></p> <p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In December 2007, Gilead Sciences Limited (GSL), a wholly-owned subsidiary in Ireland, and BMS entered into a collaboration arrangement to commercialize and distribute Atripla in the European Union, Iceland, Liechtenstein, Norway and Switzerland (collectively, the European Territory). The parties formed a limited liability company which we consolidate, to manufacture Atripla for distribution in the European Territory using efavirenz that it purchases from BMS at BMS's estimated net selling price of efavirenz in the European Territory. We are responsible for product distribution, inventory management and warehousing. Through our local subsidiaries, we have primary responsibility for order fulfillment, collection of receivables, customer relations and handling of sales returns in all the territories where we co-promote Atripla with BMS. We are also responsible for accounting, financial reporting and tax reporting for the collaboration. In December 2007, the European Commission approved Atripla for sale in the European Union. As of December&nbsp;31, 2010 and 2009, efavirenz purchased from BMS at BMS's estimated net selling price of efavirenz in the European Territory is included in inventories on our Consolidated Balance Sheets. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">The parties also formed a limited liability company to hold the marketing authorization for Atripla in Europe. We have primary responsibility for regulatory activities and we share marketing and sales efforts with BMS. In the major market countries, both parties have agreed to provide equivalent sales force efforts. Revenue and cost sharing is based on the relative ratio of the respective net selling prices of Truvada and efavirenz. </font></p> <p style="margin-top: 18px; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>PARI GmbH </b></font></p> <p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">As a result of our acquisition of Corus Pharma, Inc.

Under the terms of the agreement, we are obligated to pay PARI for services rendered, and subject to the achievement of specific milestones, we are obligated to pay certain milestone payments to PARI. In addition, we&nbsp;will make royalty payments based on net sales of Cayston. The agreement also provided&nbsp;us&nbsp;the right to reduce the royalty rate payable to PARI. In November 2007, we paid PARI $<font class="_mt">13.5</font> million to&nbsp;reduce the royalty rate under the agreement. As Cayston had not yet been approved for commercialization at the time of the payment, we recorded this payment in R&amp;D expenses in our Consolidated Statement of Income. In April 2008, pursuant to the February 2002 development agreement, we entered into a commercialization agreement with PARI which provides for the supply and manufacture of an inhalation delivery device and accessories for use with Cayston.

The agreement granted us worldwide commercialization rights to GS 9411 (formerly P-680), an ENaC inhibitor discovered by Parion, for the treatment of pulmonary diseases, including CF, chronic obstructive pulmonary disease and non-CF bronchiectasis. In accordance with the terms of the agreement, we paid a $<font class="_mt">5.0</font> million up-front license fee that was recorded in R&amp;D expenses in our Consolidated Statement of Income as there was no future alternative use for this technology, and made a $<font class="_mt">5.0</font> million investment in Parion in the form of convertible debt, which was recorded as other noncurrent assets in our Consolidated Balance Sheet. Under the collaboration agreement, we will lead all development and commercialization activities and provide funding of full time equivalent employees for certain research activities. In addition, we are obligated to make additional payments upon the achievement of certain milestones and pay royalties on future net sales of products that are developed and approved in relation to this collaboration. In August 2010, development of GS 9411 was terminated and the term of the research collaboration was extended to identify additional ENaC inhibitors for development. </font></p> <p style="margin-top: 18px; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><b>Roche </b></font></p> <p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In September 1996, we entered into a development and license agreement (the 1996 Agreement) with Roche to develop and commercialize therapies to treat and prevent viral influenza. Tamiflu, an antiviral oral formulation for the treatment and prevention of influenza, was co-developed by us and Roche. Under the 1996 Agreement, Roche has the exclusive right to manufacture and sell Tamiflu worldwide, subject to its obligation to pay us a percentage of the net revenues that Roche generates from Tamiflu sales, which, in turn, has been subject to reduction for certain defined manufacturing costs. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">In November 2005, we entered into a first amendment and supplement to the 1996 Agreement with Roche. The amended agreement provided for the formation of a joint manufacturing committee to review Roche's manufacturing capacity for Tamiflu and its global plans for manufacturing Tamiflu, a U.S. commercial committee to evaluate commercial plans and strategies for Tamiflu in the United States and a joint supervisory committee to evaluate Roche's overall commercial plans for Tamiflu on a global basis in each case, consisting of representatives of Roche and us.

In addition, under the amended agreement, royalties payable by Roche to us will no longer be subject to a cost of goods sold adjustment that was provided in the 1996 Agreement. We recorded a total of $<font class="_mt">386.5</font> million, $<font class="_mt">392.7</font> million and $<font class="_mt">155.5</font> million of Tamiflu royalties in 2010, 2009 and 2008, respectively. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">As a result of our acquisition of CV Therapeutics in April 2009, we assumed all rights to the agreement between CV Therapeutics and Roche under which we have an exclusive worldwide license to Ranexa. Under the license agreement, we paid an initial license fee and are obligated to make certain payments to Roche upon receipt of the first and second product approvals for Ranexa in any of the following major market countries: France, Germany, Italy, the United States and the United Kingdom. In January 2006, we received FDA approval for Ranexa for the treatment of chronic angina and paid $<font class="_mt">11.0</font> million to Roche in accordance with the agreement.
