The accounting principles and methods of computation adopted in these condensed consolidated financial statements are the same as those of the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. Omitted from these statements are certain information and note disclosures normally included in the audited consolidated financial statements prepared in accordance with U.S. GAAP. The Company believes all adjustments necessary for a fair statement of the results for the periods presented have been made, and such adjustments consist only of those considered normal and recurring in nature. The financial results for the three months and six months ended June 30, 2011 are not necessarily indicative of financial results for the full year. The condensed consolidated balance sheet as of December 31, 2010 has been derived from the audited financial statements at that date. The unaudited condensed consolidated financial statements and notes presented should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2010 included in the Company’s Annual Report on Form 10-K, filed with the U.S. Securities and Exchange Commission. Comprehensive Loss Comprehensive loss, which is comprised of net loss and other comprehensive income or loss, amounted to $34.0 million and $4.3 million for the three months ended June 30, 2011 and 2010 respectively, and $41.2 million and $5.1 million for the six months ended June 30, 2011 and 2010, respectively. The Company’s other comprehensive income or loss includes unrealized gains and losses on its available-for-sale short-term investments. Revenue Licensing Revenue from Collaborative and License Agreements. Revenue from collaborative and license agreements consists of (1) up-front cash payments for initial technology access or licensing fees and (2) contingent payments triggered by the occurrence of specified events or other contingencies derived from the Company’s collaborative and license agreements. Royalties from the commercial sale of products derived from the Company’s collaborative and license agreements are reported as licensing, royalties and other revenue. If the Company has continuing obligations under a collaborative agreement and the deliverables within the collaboration cannot be separated into their own respective units of accounting, it utilizes a multiple attribution model for revenue recognition as the revenue related to each deliverable within the arrangement should be recognized upon the culmination of the separate earnings processes and in such a manner that the accounting matches the economic substance of the deliverables included in the unit of accounting. As such, (1) up-front cash payments are recorded as deferred revenue and recognized as revenue ratably over the period of performance under the applicable agreement and (2) contingent payments are recorded as deferred revenue when all the criteria for revenue recognition are met and recognized as revenue ratably over the estimated period of the Company’s ongoing obligations. Royalties based on reported sales of licensed products, if any, are recognized based on the terms of the applicable agreement when and if reported sales are reliably measurable and collectability is reasonably assured. If the Company has no continuing obligations under a license agreement, or a license deliverable qualifies as a separate unit of accounting included in a collaborative arrangement, license payments that are allocated to the license deliverable are recognized as revenue upon commencement of the license term and contingent payments are recognized as revenue upon the occurrence of the events or contingencies provided for in such agreement, assuming collectability is reasonably assured.
