Gross margin improved from a loss of $1,734,000 (-480% of sales) in 2004 to a loss of $292,000 (-45% of sales) in 2005 primarily as a result of transition costs attributable to our Legacy Business in both years. Under the terms of the manufacturing services agreement with Maxim, our gross margin on the Legacy Business has been significantly reduced compared with the higher labor and overhead costs incurred during the third quarter of 2004, when we were manufacturing the Western Blot products at Rockville, Maryland and transitioning the EIA manufacturing processes there, following our second quarter closure of our Alameda, California EIA screening test manufacturing facility. Additionally, the increase in sales of our BED incidence tests has improved our gross margin.
Research and development costs decreased by $104,000 or 20%, from $509,000 in 2004 to $405,000 in 2005. The decrease reflects the elimination of our former R&D staff and related operations at Rockville in response to the implementation of our business restructuring. We continued to incur travel and other costs related to the transfer of our manufacturing technology to Thailand and China and for various international clinical trials of our rapid tests during the third quarter of 2005. We also incurred costs related to the transfer of technology for our BED incidence test to a contract manufacturer in the Portland, Oregon area in the third quarter of 2005.
Selling, general and administrative costs decreased by $392,000 or 26%, from $1,487,000 in 2004 to $1,095,000 in 2005. The primary components of the decrease include the following:
o a decrease of approximately $150,000 in selling expenses, primarily due to the reduction in outside consultant expenses;
o a reduction of approximately $175,000 in compensation and travel and entertainment expenses primarily related to the elimination of the position of Executive Chairman in the fourth quarter of 2004 as well as the elimination of the former Rockville and Pleasanton administrative staff.
Our loss from operations for the third quarter of 2005, at $1,792,000, reflects a 51% decrease compared with the $3,730,000 loss reported for the third quarter of 2004.
We recorded net interest expense of $1,067,000 for the third quarter of 2005 compared with $79,000 of interest income in the third quarter of 2004 principally due to the accounting for the derivative and anti-dilution obligations of our recent financings which are required to be adjusted to their fair value at each balance sheet date with the change in value being recognized in interest expense.
