Revenues received from the Company's royalty products for the quarter ended June 30, 2010 were $10.6 million, as compared to $13.2 million for the quarter ended June 30, 2009. Royalties on PEGINTRON, marketed by Merck & Co., Inc., continue to comprise the majority of the Company's royalty revenue. Royalty revenues were impacted by lower PEGINTRON sales as well as the loss of Pegasys royalties which ended in October 2009. The Company continues to evaluate the possible sale of its PEGINTRON royalty stream, with consideration given to the impact on after tax return to shareholders as well as developments in the HCV drug market.
In order to effectively transition its specialty pharmaceutical business, Enzon agreed to perform ongoing general, administrative, and selling services as needed by the purchaser on a contracted basis. The agreement provides for Enzon to be reimbursed at cost plus a mark-up for all expenses incurred on the requested services. During the second quarter of 2010, Enzon recognized $0.5 million in revenue associated with this service and a related $0.4 million of expense.
General and Administrative
General and administrative expenses decreased to $5.8 million for the quarter ended June 30, 2010, as compared to $10.1 million for the second quarter of 2009. The decrease is due in large part to the Company’s ongoing cost control initiatives. Also, reflected in the second quarter results are the favorable effects of the fourth-quarter 2009 and first-quarter 2010 acceleration of share-based compensation and the first quarter of 2010 restructuring program, both of which reduced ongoing compensation costs. The Company has made significant progress in reducing expenses and will continue to identify and implement efficiencies that will potentially further reduce general and administrative costs. However, the rate of improvement experienced during the second quarter of 2010 is not expected to continue.
