Thanks Bob.
Net revenues for the quarter ended June 30, 2010 were $15.3 million compared to $9.5 million for the first quarter of 2010, an increase of $5.7 million or 60%. Net income for the second quarter of 2010 was $3.2 million, or $0.31 per diluted share, compared to $1.1 million, or $0.11 per diluted share, for the first quarter of 2010.
For the second quarter of 2010, end user net revenue was $12.3 million or 81% of net revenues compared with $7.1 million or 75% of net revenues in the first quarter.
OEM net revenue was $2.9 million or 19% of net revenues in the second quarter compared to with $2.4 million or 25% of net revenues in the first quarter.
Net revenues for markets outside of semiconductor test were $2.1 million or 14% of net revenues in the second quarter compared to $1.3 million or 14% of net revenues in the first quarter.
On a product segment basis, net revenues for the mechanical products segment was $7.8 million or 51% of net revenues in the second quarter compared with $4.7 million or 49% of net revenues in the first quarter.
Our thermal products segment had net revenues of $4.7 million or 31% of net revenues in the second quarter compared to $3.5 million or 37% of net revenues in the first quarter.
And finally, our electrical products segment reported net revenues of $2.7 million or 18% of net revenues in the second quarter of 2010 compared with $1.3 million or 14% of net revenues in the first quarter.
The Company's overall gross margin for the quarter ended June 30, 2010 was $7.4 million or 48.3% of net revenues compared to $4.5 million or 47.6% of net revenues for the first quarter. Improvement in our percentage gross margin quarter-over-quarter was driven by the significantly higher net revenue levels and better absorption of our fixed manufacturing costs, which declined from 14.8% of our net revenues in the first quarter to 11% in the second quarter. This improvement was almost fully offset by an increase in our material costs, which was 36.8% of net revenues in the second quarter compared to 33.6% in the first quarter.
The significant increase in our material costs as a percentage of net revenues reflects changes in our product and customer mix during the second quarter compared to the first. While all three product segments experienced increases in their material costs as a percentage of revenue quarter-over-quarter, the majority of the increase in this percentage was driven by changes in the mechanical product segment and its sales of manipulator and docking hardware products.
While manipulator sales, as a percentage of this segment's net revenue declined slightly from 29% in the first quarter to 27% in the second quarter, our manipulator material costs increased from 56.4% of this segment's first quarter revenue to 70.3% in the second quarter. Furthermore, our docking hardware sales were relatively consistent as a percentage of mechanical products segment's revenues, 63% in the first quarter and second quarter, while docking hardware material costs increased from 27% of this segment's first quarter revenue to 32.3% in the second quarter.
The increases in material cost as a percentage of revenue for both our manipulator and docking hardware products was driven by changes in product mix with the second quarter having a higher percentage of lower margin products coupled with changes in customer mix with the second quarter having a higher level of discount being offered to our customers.
While our fixed manufacturing cost as a percentage of net revenues declined quarter-over-quarter, these costs increased in absolute dollar terms by $270,000 or 19% over the prior quarter. The increase was primarily related to changes in the level of capitalized labor and overhead due to reductions in inventory in our thermal products segment as well as increases in service materials procured by our mechanical products segment.
In addition, there was also an increase in salary and benefit expense due to production overtime paid during the quarter and the restoration of the 401(k) match on April 1, 2010 for all domestic employees. Another item impacting our gross margin were our accruals for excess and obsolete inventory, which were $211,000 or approximately $0.02 per diluted share in the second quarter compared to $142,000 in the first quarter. The accruals during the second quarter increased due to certain inventory risks that management has taken in response to the increased business levels.
Many of our customers are ordering from us expecting delivery in four to six weeks on average and we have certain component parts that have lead times of 10 to 12 weeks. So we're required to take inventory risks and make estimates of what our customers will order so we can accommodate the four to six week delivery times requested.
I will now discuss the breakdown of operating expenses for the quarter. Selling expense for the second quarter was $1.8 million or 12% of net revenues compared to $1.2 million or 13% of net revenues in the first quarter, an increase of $525,000 or 43%. The increase was primarily due to a $410,000 increase in sales commission expense due to the higher revenue levels. In addition, we accrued $88,000 or approximately $0.01 per diluted share for product warranty expense due to increased revenue levels.
Engineering and product development expense was $787,000 or 5% of net revenues for the second quarter compared to $701,000 or 7% of net revenues in the first quarter, an increase of $86,000 or 12%. The increase was primarily driven by the restoration of the 401(k) match and to a lesser extent to increases in spending on product development materials and third party research consultants.
General and administrative expense was $1.7 million or 11% of net revenues in the second quarter compared to $1.5 million or 16% of net revenues in the first quarter, an increase of $172,000 or 12%. The increase was primarily driven by accruals for profit related bonuses and to a lesser extent to the restoration of the 401(k) match. These increases were partially offset by the reversal of our accrual related to the audit requirements of Section 404(b) of the Sarbanes Oxley Act for which an exemption for companies with less than $75 million in market capitalization was recently adopted.
Consolidated headcount, which includes temporary staff, was 127 at June 30, 2010, up 10 from 117 at March 31, 2010. Headcount additions were in production and material handling areas and were made early in the second quarter due to the significant increase in net revenues we were experiencing. We do not expect to have any significant headcount additions for the balance of 2010 and expect that we will reduce our temporary staff headcount depending on business levels in the second half of 2010.
As previously noted, we restored the 401(k) match for all domestic employees on April 1, 2010 and our total 401(k) match expense was $193,000 for the second quarter of 2010. We expect the expense incurred in the second quarter to be the highest for the year, as many highly compensated employees received either a significant portion or their full match during the quarter.
Other expense was $8,000 for the second quarter compared to $11,000 for the first quarter of 2010 and we recorded an income tax benefit of $2,000 for the second quarter compared to an income tax expense of $3,000 in the first quarter. At the end of the second quarter our federal net operating loss carry forward was approximately $7.9 million and our state NOLs ranged from $300,000 to approximately $2.4 million depending on the state in question.
Cash and cash equivalents at the end of June were $3.1 million, up $261,000 from the $2.9 million at March 31, 2010. Please note this does not include $500,000 of restricted certificates of deposit.
We continue to expect to build cash throughout 2010, given the significant rebounds in our business and the increased level of our receivables on our balance sheet. Shortly after the close of the third quarter of 2010, we were required to make the first of four annual principal installments of $381,000 under the notes to shareholder related to our acquisition of Sigma. Interest on these notes accrues at prime plus 1.25%. We currently plan to retire the full $1.5 million of these notes prior to the end of the third quarter depending on our cash collection.
Capital expenditures during the second quarter of 2010 were $21,000 compared to $54,000 during the first quarter of 2010. We are currently scheduled to relocate of our Cherry Hill operation, which houses the manufacturing plant for our mechanical products segment as well as our corporate offices, during the fourth quarter of 2010.
We do not currently anticipate our cost for this move will exceed $200,000. The terms of our new lease provide for three months of free rent at the beginning of the lease, which will offset most of the cash flow impact of our move costs. We currently expect this new facility will reduce our annual operating expenses by at least $250,000 annually.
Our backlog at the end of the second quarter was $6 million compared to $9.1 million at the end of the first quarter.
In terms of financial outlook, as noted in our earnings release, we expect that our net revenues and net income for the third quarter ended September 30, 2010 will be between the levels achieved in the first and second quarters of 2010 due to the reduced bookings we experienced in the second quarter. This outlook is based upon the Company's current views with respect to operating and market conditions, customer forecasts and is subject to change.
Operator, that concludes our formal remarks, we can now take questions.
