Research and development expenses for the fourth quarter 2012 were $5.4 million, compared to $5.5 million in the fourth quarter 2011. Research and development expenses for the full year 2012 were $21.4 million, a 35% decrease from $33.0 million in 2011. The decrease in research and development expenses was primarily the result of lower costs associated with the Phase 3 clinical trials for Zohydro ER, which were completed in 2011, and an upfront fee paid in July 2011 upon execution of the Relday license agreement.

Selling, general and administrative expenses for the fourth quarter 2012 were $11.9 million, a 33% decrease from $17.8 million in the fourth quarter 2011. The decrease in selling, general and administrative expenses was primarily the result of a $5.7 million decrease in service fees to Astellas due to the termination of the co-promotion agreement on March 31, 2012.

Selling, general and administrative expenses for the full year 2012 were $49.5 million, an 18% decrease from $60.5 million in 2011. The decrease in selling, general and administrative expenses was primarily the result of a $10.8 million decrease in service fees to Astellas due to the March 31, 2012 termination of the co-promotion agreement and a decrease in advertising and promotional expenses. This was partially offset by an increase in field sales force costs.

Other income for the fourth quarter was $13.6 million, which includes a $15.4 million non-cash mark-to-market adjustment in the fair value of the Company's outstanding warrants. Other income for the full year 2012 was not significant on a net basis. A table with a full description of other income and expense is included in this release.
