Cost of Revenues and Gross Margin
Cost of product sales. Cost of product sales decreased by $1.5 million, or 35.8%, to $2.7 million for the year ended December 31, 2006 from $4.2 million for the year ended December 31, 2005. Costs associated with our assembly products accounted for $2.6 million of our total cost of product revenues for the year ended December 31, 2006. The decrease in cost of product sales for the year ended December 31, 2006 was attributable to the acquisition of Valor Denmark in the first half year of 2006. Prior to the acquisition of Valor Denmark, we accounted for Valor Denmark using the equity method of accounting. This ceased to be the case upon our acquisition of 100% of the interests in Valor Denmark in May 2006. Product gross margin increased to 87.4% for the year ended December 31, 2006 from 81.6% for the year ended December 31, 2005 as we were no longer required to recognize cost of product sales from sales of Valor Denmark’s TraceXpert software.
Cost of services. Cost of services revenues decreased by $0.4 million, or 18.6%, to $1.9 million for the year ended December 31, 2006 from $2.3 million for the year ended December 31, 2005. Cost of services associated with our assembly, fabrication and design software solutions accounted for $0.9 million, $0.4 million and $0.6 million, respectively, of our cost of services for the year ended December 31, 2006. Services gross margin increased to 87.4% for the year ended December 31, 2006 from 82.3% for the year ended December 31, 2005. The increase in cost of services revenues for the year ended December 31, 2006 was attributable to the fact that the growth rate of services revenues was higher than the cost to us of supporting our customers covered by software maintenance agreements. Cost of services is comprised of costs related to field customer support personnel, which vary based upon the specific services provided, and costs related to engineering personnel that support our software solutions on an ongoing basis. The former may fluctuate based on the scope of the work required, whereas the latter remain relatively constant.
Operating Expenses
Research and development. Research and development expenses increased by $2.6 million, or 28.1%, to $11.8 million for the year ended December 31, 2006 from $9.2 million for the year ended December 31, 2005. Research and development associated with our assembly, fabrication and design software solutions accounted for $8.7 million, $2.5 million and $0.6 million, respectively, of our research and development expenses for the year ended December 31, 2006. The increase in research and development expenses for the year ended December 31, 2006 was attributable primarily to growth in the number of employees engaged in research and development activities from 103 as of December 31, 2005 to 123 as of December 31, 2006. The increase in research and development personnel for the year ended December 31, 2006 was related entirely to our acquisition of 100% of the interests in Valor Denmark in May 2006. Research and development expenses as a percentage of revenues increased to 30% for the year ended December 31, 2006 from 25.3% for the year ended December 31, 2005.
Marketing and selling. Marketing and selling expenses decreased by $1.3 million, or 8.5%, to $14.8 million in 2006 from $16.1 million in 2005. Marketing and selling expenses associated with our assembly, fabrication and design software solutions accounted for $8.7 million, $3.0 million and $3.1 million, respectively, of our marketing and selling expenses for the year ended December 31, 2006.
The decrease in marketing and selling expenses for the year ended December 31, 2006 resulted from us shifting part of our employee base at the end of 2005 from the United States to the Far East where cost of employment is cheaper. This led to a disproportionate amount of marketing and selling expenses in 2005 which did not recur in 2006. Marketing and selling expenses as a percentage of revenues decreased to 40.2% for the year ended December 31, 2006 from 44.4% for the year ended December 31, 2005.
General and administrative.General and administrative expenses were $2.4 million for the year ended December 31, 2006 and the year ended December 31, 2005. General and administrative expenses associated with our assembly, fabrication and design software solutions accounted for $1.8 million, $0.4 million and $0.2 million, respectively, of our marketing and selling expenses for the year ended December 31, 2006.
General and administrative expenses as a percentage of revenues were 6.6% for the year ended December 31, 2006 and 6.5% for the year ended December 31, 2005.
Financial Income/Expense
Financial income/expense increased on a combined basis to $1.1 million for the year ended December 31, 2006 from $0.4 million for the year ended December 31, 2005. This increase resulted from an increase in income from interest from bank deposits and gain on sale of marketable securities. In addition, for the year ended December 31, 2005, we had a higher level of exchange rate expenses compared with the year ended December 31, 2006.
