Contributing to the current period loss were lower revenues, the Company's expenditures related to ongoing clinical development programs, and medical education and awareness programs associated with pseudobulbar affect (PBA), also known as emotional lability. Research and development (R&D) expenses for the fourth quarter of fiscal 2003 amounted to $5.6 million, compared to $4.0 million for the same period a year ago. The Company continued working on the following clinical trials and studies during the fourth fiscal quarter: - A Phase III clinical trial of Neurodex(TM) for the treatment of PBA in patients with multiple sclerosis; - An open-label study of Neurodex in the treatment of PBA in a diverse population of patients with neurologic disorders; - A Phase I clinical trial of AVP-13358 for the treatment of allergy and asthma; and - Preclinical research on potential treatments for inflammatory diseases, cholesterol reduction and infectious disease. Expenditures on R&D programs accounted for 72% of total operating expenses for the fourth quarter of fiscal 2003, compared to 70% of total operating expenses for the same period a year ago. Revenues for the fourth fiscal quarter ended September 30, 2003 were $600,000, compared to $1.2 million for the same period a year ago. Revenues for the current period included $402,000 that the Company recognized from the sale of Abreva(R) royalty rights to Drug Royalty USA, based on actual Abreva royalties of $1.0 million that were due Drug Royalty USA by GlaxoSmithKline. In fiscal 2003, Avanir sold an undivided interest in its Abreva license agreement to Drug Royalty USA for $24.1 million and recorded the amount as deferred revenue, to be recognized ratably as revenue over approximately the 11 years remaining under the license agreement. Avanir also earned $193,000 from government research grants. Revenues for the same period a year ago included primarily $879,000 in Abreva royalties earned and paid directly to Avanir by GlaxoSmithKline and $132,000 in government research grants. 1 FISCAL YEAR RESULTS The net loss attributable to common shareholders in fiscal 2003 amounted to $23.3 million, or $0.39 per share, compared to $10.3 million, or $0.18 per share for the same period a year ago. Contributing to the loss were higher R&D program costs and lower revenues from milestones in license agreements. Operating expenses for fiscal 2003 amounted to $25.9 million, compared to $19.5 million in fiscal 2002. The 33% increase in operating expenses was primarily due to a 36% increase in R&D expenses. Total R&D expenses in fiscal 2003 amounted to $18.6 million, compared to $13.6 million for the same period a year ago.
