• On January 26, 2012, Biogen Idec and Elan Corporation announced a global Phase IIIb study, ASCEND, that is being conducted to evaluate the effectiveness of TYSABRI as a treatment for secondary-progressive multiple sclerosis (SPMS). According to the National Multiple Sclerosis Society, approximately half of all people initially diagnosed with relapsing-remitting multiple sclerosis (RRMS) - the most common form of multiple sclerosis (MS) - will transition to SPMS within 19 years.
• On January 20, 2012, Biogen Idec and Elan Corporation announced the U.S. Food and Drug Administration (FDA) approved a product label change for TYSABRI that will help enable individual benefit risk assessment for patients with multiple sclerosis (MS). The new label identifies anti-JCV antibody status as a risk factor for developing an infrequent but serious brain infection known as progressive multifocal leukoencephalopathy (PML). This marks the third risk factor identified to help physicians and people with MS make personalized treatment decisions when considering TYSABRI, a highly effective treatment for relapsing forms of MS.
• On January 4, 2012, Biogen Idec and Isis Pharmaceuticals announced they entered into an exclusive, worldwide option and collaboration agreement under which the companies will develop and commercialize Isis’ antisense investigational drug, ISIS-SMNRx, for the treatment of spinal muscular atrophy (SMA). Biogen Idec has the option to develop and commercialize this promising compound for the most common genetic cause of infant mortality and will offer its expertise in neurology to aid in rapid development.
• On December 5, 2011, Samsung and Biogen Idec announced they entered into an agreement to invest $300 million to establish a joint venture to develop, manufacture and market biosimilars. Samsung will take a leading role in the joint venture, with Biogen Idec contributing its expertise in protein engineering and biologics manufacturing.

Use of Non-GAAP Financial Measures

Our “non-GAAP net income attributable to Biogen Idec Inc.” and “non-GAAP diluted EPS” financial measures exclude the following items from GAAP net income attributable to Biogen Idec Inc. and diluted EPS:

1. Purchase accounting and merger-related adjustments.

We exclude certain purchase accounting impacts, such as those related to the 2003 merger between Biogen, Inc. and Idec Pharmaceuticals, Inc., the acquisitions of Fumapharm AG, Conforma Therapeutics, Syntonix Pharmaceuticals, and Panima Pharmaceuticals AG and the consolidation of Knopp and Cardiokine. These include charges for in-process research and development and amortization of the acquired intangible assets. Excluding these charges provides management and investors with a supplemental measure of performance in which the Company’s acquired intellectual property is treated in a comparable manner to its internally developed intellectual property.

2. Stock option expense recorded in accordance with the accounting standard for share-based payments.

We believe that excluding the impact of expensing stock options better reflects the recurring economic characteristics of our business. We exclude stock option expense from our non-GAAP R&D expenses and SG&A expenses, but include the impact of all other share-based awards and cash incentives in our non-GAAP results.

3. Other items.

We evaluate these on an individual basis, and consider both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to our ongoing business operations, and (iii) whether or not we expect it to occur as part of our normal business on a regular basis.

We believe it is important to share these non-GAAP financial measures with shareholders as they better represent the ongoing economics of the business, reflect how we manage the business internally and set operational goals, and form the basis of our management incentive programs. Non-GAAP net income attributable to Biogen Idec Inc. and diluted EPS should not be viewed in isolation or as a substitute for reported, or GAAP, net income attributable to Biogen Idec Inc. and diluted EPS.
