Thank you, Bob. Net revenues for the quarter ended June 30, 2012 of $13.6 million increased 27% over first quarter net revenues of $10.7 million and decreased when compared with second quarter 2011 net revenues of $13.8 million.
First quarter end user net revenues were $11.3 million, or 83% of net revenues, compared with first quarter end user net revenues of $9.1 million. OEM net revenues were $2.3 million or 17% of net revenues, compared with first quarter OEM net revenues of $1.6 million. Net revenues from markets outside of semiconductor test were $1.8 million, or 14% of net revenues, compared with $2.4 million, or 22% of net revenues in the first quarter.
The Company's overall gross margin for the second quarter was $6.2 million, or 46%, as compared with $4.6 million, or 43%, in the first quarter of 2011. The improvement in gross margin was driven by a better absorption of our fixed manufacturing costs in the second quarter, which while fixed in dollar amount at $1.8 million, declined from 17% of revenues in the first quarter to 13% of revenues in the second quarter. The improvement in the margin caused by the better absorption of fixed manufacturing costs was offset by an increase in component material costs, due to a less favorable product mix in the second quarter.
Our consolidated material cost in the second quarter of 2012 was 37.8% compared to 36.3% in the first quarter. The material cost in our Mechanical Products segment increased from 44.2% in the first quarter to 45.8% in the second quarter, due to a slight increase in the percent of manipulator products shipped in the quarter, which increased by 1% to 33% of Q2 Mechanical sales, as well as a slight reduction in the net margin for manipulator products, which declined by 1% to 26% in the second quarter. The material cost in our Thermal Products segment increased to 31.8% in the second quarter from 30.1% in the first quarter, due to the impact of the Thermonics acquisition. Offsetting these increases was a reduction in the material cost in our Electrical Products segment, which declined from 44.5% in the first quarter to 41.3% in the second quarter.
I will now discuss the breakdown of operating expenses.
Selling expenses for the second quarter were $1.6 million, or 12% of net revenues, compared with $1.4 million or 13% of net revenues for the first quarter, an increase of $149,000 or 11%. The increase was primarily due to increased sales commission expense on higher levels of revenues and increased advertising costs, which were partially offset by reductions in third party installation costs and warranty expense.
Second quarter engineering and product development expense was $980,000, or 7% of net revenues, compared with $924,000, or 9% of net revenues, an increase of $56,000 or 6%. The increase was due to higher levels of spending on product development materials in the second quarter in our Thermal and Electrical Products segments.
General and administrative expense for the second quarter was $1.7 million, or 12% of net revenues, compared with $2.0 million, or 19% of net revenues in the first quarter, a decrease of $326,000 or 16%. First quarter G&A expenses included non-recurring Thermonics acquisition related expenses of $433,000 and move related expenses for our Electrical Products operation of $39,000; there were no comparable expenses in the second quarter of 2012. Amortization of intangibles also declined in the second quarter. These decreases were partially offset by increases in profit related bonuses and corporate legal costs.
There were no restructuring or other charges in the second quarter compared to $359,000 in the first quarter. The restructuring charges in the first quarter were related to the relocation of the Thermonics operations from California to Massachusetts.
Other Income for the first quarter was zero compared to $13,000 for the-excuse me other income for the second quarter was zero compared to $13,000 for the first quarter, with the reduction caused by foreign exchange losses for the period.
Income tax expense was $660,000 for the second quarter compared with an income tax benefit of $28,000 in the first quarter. Our effective tax rate in the second quarter was 33%, which was higher than the 25% effective tax rate guidance that had been provided. We now expect our effective tax rate will range between 35% and 39% going forward, depending on the pro-ration of our domestic and foreign earnings. At June 30, 2012, we had total deferred tax assets of $2.2 million.
Second quarter net income was $1.3 million or $0.13 per diluted share, compared with the first quarter net loss of $43,000, or $0.00 per diluted share. Included in the first quarter results were approximately $914,000 in non-recurring expenses associated the acquisition and relocation of Thermonics and the relocation of our Electrical Products Segment. On a per share basis, these items represented $0.07 per diluted share when tax effected using our 17% domestic effective tax rate for the first quarter of 2012.
Consolidated headcount at the end of June (which includes temporary staff) was 147, an increase of six staff during the second quarter. The additions in staff were primarily in our Thermal Products Segment in response to the Thermonics acquisition. Thermonics second quarter revenues were $1.4 million, up from $669,000 in the first quarter. The net operating contribution from the Thermonics revenue was approximately 40%.
As we have noted before, we closely monitor our resource levels and will adjust as needed when we see any prolonged softness in demand levels.
I will now turn to the balance sheet.
Cash and cash equivalents at the end of the second quarter were $11.7 million. We currently expect cash and cash equivalents to increase sequentially for the balance of 2012.
Accounts receivable at the end of the second quarter was $9.3 million, an increase of $1.3 million during the quarter. The increase was driven by higher levels of net revenues in the second quarter compared to the first, as well as an increase in days sales outstanding, which were 66.4 days at June 30th.
Inventory declined by approximately $300,000 to $4.4 million at the end of June.
During the second quarter, we completed the purchase price allocation for our Thermonics acquisition and the final goodwill number decreased from $179,000 at the end of March to $50,000 at the end of June. The change in goodwill was driven by an adjustment to the inventory values determined at closing.
Capital expenditures during the second quarter were $129,000 compared to zero in the first quarter. The capital expenditures were related to the new facility for our Electrical Products Segment located in Freemont, California.
Bob provided the consolidated and segment booking data earlier in the call; for the quarter ended June, 30th, Thermonics bookings were $1.4 million, compared to $553,000 in the first quarter. The backlog at the end of the second quarter was $5.2 million, down from $7.0 million at the end of the first quarter. Thermonics backlog was $744,000 at June 30, 2012.
In terms of our financial outlook, as noted in our earnings release, we expect that net revenues for the quarter ended September 30, 2012 will be in the range of $9.5 to $10.5 million with net earnings ranging from breakeven to $0.04 per diluted share. We currently expect that our Q2-or excuse me, our Q3 2012 material costs as a percentage of revenues will range from 36% to 38% due to a less favorable product mix.
Please note that our outlook is based on the Company's current views with respect to operating and market conditions and customers' forecasts, which are subject to change.
Operator, that concludes our formal remarks. We can now take questions.
