Thanks Bob.
Net revenues for the quarter ended December 31, 2009 were $8.4 million compared to $6.0 million for the third quarter of 2009, an increase of $2.4 million or 40%. The net income for the fourth quarter of 2009 was $142,000 or $0.01 per diluted share, compared to a net loss of $278,000 or $0.03 per diluted share for the third quarter of 2009. For the fourth quarter of 2009 end user net revenue was $6.6 million or 79% of net revenues compared with $5.2 million or 87% of net revenues in the third quarter of 2009. OEM net revenue was $1.8 million or 21% of net revenues in the fourth quarter of 2009, compared with $747,000 or 13% of net revenues in the third quarter. Net revenues from markets outside of semiconductor tests were $650,000 or 7% of net revenues in the fourth quarter of 2009, compared to 527,000 or 8% of net revenues in the third quarter of 2009.
On a product segment basis, net revenues for the Mechanical Products segment were $4.5 million or 54% of net revenues in the fourth quarter of 2009 compared with $2.3 million or 38% of net revenues in the third quarter.
Our Thermal Products segment had net revenues of $3.1 million or 37% of net revenues in the fourth quarter of 2009 compared with $2.7 million or 45% of net revenues in the third quarter.
Finally our Electrical Products segment reported net revenues of $835,000 or 9% of net revenues in the fourth quarter of 2009, compared with a million or 17% of net revenues in the third quarter. The Company's overall gross margin for the quarter ended December 31, 2009 was $3.2 million or 37.5% of net revenues, compared to $2.4 million or 40.5% of net revenues for the third quarter of 2009. Material cost was 39.2% of net revenues in the fourth quarter, compared to 30.3% in the third quarter. The reduction in gross margin as a percentage of net revenues in the fourth quarter was the result of higher component material costs due to shifts in product mix.
I'll now discuss the breakdown of operating expenses for the quarter. Selling expense was $1.2 million or 14% of net revenues for the fourth quarter compared to $988,000 or 16% of net revenues in the third quarter, an increase of $184,000 or 19%. The increase was primarily due to increased sales commission expense due to higher levels of sales, and to a lesser extent to higher levels of salary expense resulting from the restoration of temporary salary reductions for employees. Engineering and product development expense was $570,000 or 7% of net revenues for the fourth quarter compared to $515,000 or 9% of net revenues in the third quarter, an increase of $55,000 or 11%. The increase was primarily due to increased spending on research and development materials, and to a lesser extent to higher levels of salary expense. These increases were offset by reduced spending on patent legal cost.
General and administrative expense was $1.2 million or 15% of net revenues in the fourth quarter compared to $1.2 million or 19% of net revenues in the third quarter, an increase of $65,000 or 6%. The increase was primarily related to increased salary expense as well as higher levels of professional fees and travel expenses. These increases were partially offset by reduced levels of audit fees and corporate legal expenses as well as bad debt expense.
Restructuring and other charges were $307,000 for the fourth quarter compared to $27,000 in the third quarter. Fourth quarter restructuring charges were for one-time termination benefits and facility closure costs related to the relocation of our Sigma Systems operation, while the charges in the third quarter related to facility closure costs for our Japanese operation, which we closed during the third quarter of 2009. The Company has significantly reduced staff over the last year. Consolidated headcount has been reduced from 175 employees at December 31, 2008 to 107 employees as of December 31, 2009, a reduction of 68 staff or 39%.
Other income was $209,000 in the fourth quarter of 2009, compared to other expense of $18,000 in third quarter. Other income in the fourth quarter included approximately $184,000 of foreign exchange gains related to the dissolution of our Japanese subsidiary, which was completed in late December. Our pre-tax income was $96,000 or $0.01 per diluted share for the fourth quarter, compared to a pre-tax loss of $(277,000) or $(0.03) per diluted share in the third quarter.
We recorded an income tax benefit of $46,000 for the fourth quarter compared to income tax expense of $1,000 for the third quarter. The income tax benefit was related to a deferred tax asset booked in our Singapore operation. Our effective tax rates in both periods were not meaningful. Our net income for the fourth quarter of 2009 was $142,000 or $0.01 per diluted share, compared to a net loss of $(278,000) or $(0.03) per diluted share for the third quarter, and diluted average shares outstanding were approximately 10 million for both the third and fourth quarters of 2009.
We expect to be profitable in the first quarter of 2010 and for all of 2010 at this time. We have had a number of requests from investors to begin providing both revenue and EPS guidance and our board recently met and determined that they would prefer to not provide this detailed level of guidance at this time.
Cash and cash equivalents at December 31, 2009 were approximately $2.6 million, down $781,000 from the $3.4 million at the end of September. Our cash burn during 2009 was $4.5 million. Our cash and cash equivalents as of March 19, 2010 were $3.2 million. We currently expect to build cash throughout 2010, although with a significant increase in our business recently we may have some reductions in cash as we purchase inventory to fulfill orders for the second quarter and beyond.
During the fourth quarter we retained a third party financial intermediary to assist us in putting a $2.0 million revolving credit facility in place secured by the Company's assets. After receiving proposals from several lenders we determined that in light of our improved business results and the positive trends we're experiencing in working capital we would not move forward with putting the revolving credit facility in place at the current time. We believe we will be able to finance our operations with cash flow provided from operations throughout 2010.
Capital expenditures during the fourth quarter of 2009 were $25,000 compared to $20,000 during the third quarter. As Bob previously noted, bookings increased in the fourth quarter of 2009 to $9.4 million from $7.9 million in the third quarter, an increase of $1.5 million or 19%. Our bookings included non-semiconductor related orders of $830,000 or 9% of total orders in the fourth quarter of 2009 compared to $584,000 or 8% of total orders booked in the third quarter. Our backlog at the end of the fourth quarter was $4.5 million, up from $3.6 million at the end of the third quarter.
That's it for my financial review at this time. We will now open up for questions-and-answers.
