Thanks, Terry. I will start with the financial update. DexCom generated $21.1 million in product revenue for the third quarter of 2012, compared to $16.7 million for the same quarter in 2011, a $4.4 million or 27% increase. During our G4 PLATINUM approval conference call in early October, we stated that we expected product revenue for Q3, 2012 due to be approximately $22.2 million prior to any adjustments related to our G4 PLATINUM launch and subject to completion of our closing processes.
After internal analysis and review by independent auditors, it was determined that we should reserve an additional $1.2 million for sales returns related to our 30 day money back guarantee on DexCom hardware. As we discussed during the G4 PLATINUM approval call DexCom has always maintained a 30 day full refund policy on our hardware. As part of our G4 PLATINUM launch, we elected to extend this offer for patients who purchased SEVEN PLUS hardware from September 1 through our G4 PLATINUM announcement date of October 5, while historically very few patients have returned products under the terms of our 30 day money back guarantee, we expect a significant number of patients to take advantage of the offer through exchange for G4 PLATINUM.
This $1.2 million reserve resulted in a dollar for dollar reduction of product revenue for the quarter. Our product revenue growth for Q3 2012 over Q3 2011 would have been 34% without this increase in the returns reserves. It is also important to note that we plan to recognize most of this reserve as product revenue during the fourth quarter of 2012 as we shift G4 PLATINUM hardware to these patients.
Sequentially, product revenue for Q3 2012 decreased 2% from the prior quarter. However excluding these additional sales returns reserves, product revenue would have increased 3% sequentially.
As we stated in our G4 PLATINUM approval call, we believe that many purchase decisions during Q3 were deferred as patients and health care providers anticipated the G4 PLATINUM approval and introductions. Total revenue for the third quarter of 2012 was $23.1 million, compared to $18.3 million during the same quarter in 2011.
Our product gross profit totaled $7.7 million, generating a gross margin of 36% for Q3 2012, compared to a gross profit of $7.4 million and a gross margin of 45% for the same quarter in the prior year. As we discussed during the G4 PLATINUM approval call, we recorded a number of one-time charges that have negatively affected our gross profit and gross margin for the quarter, specifically we recognize approximately $500,000 in cost of goods sold from SEVEN PLUS hardware we shift in September, where we recognize no revenue related to those shipments due to the increased sales returns reserve discussed previously.
We also wrote off approximately $2.5 million in excess of obsolete inventory related both to the SEVEN PLUS and the SEVEN PLUS upgradeable product we discussed during the G4 PLATINUM call that we no longer expect to sell, and we shortened the useful life of and recorded additional depreciation expense of approximately $600,000 related to certain fixed assets used for SEVEN PLUS manufacturing and testing.
Absent these onetime charges, our product gross profit would have been $11.9 million generating a product gross margin of approximately 54%. Sequentially, our product gross profit decreased $2.9 million on decreased sales of $400,000 over the prior quarter and our gross margin decreased 13 margin points. However, excluding the charges we've discussed our product gross profit would have increased $1.3 million; our corresponding gross margin would have increased approximately 5 margin points over the prior quarter.
Some final thoughts on our revenue and gross profits during Q3. Our split between consumable and durable revenues was again between 70% and 75% consumables and between 20% to 30% durables and the ASP for sensors remained constant while the ASP for our durables was affected slightly by our rebate program for SEVEN PLUS which was offered only during the month of September. Our international business continue to perform well in Q3 accounting for just under 10% of our product revenue in the quarter.
On the domestic distributor front, our revenue split between direct and distributor business remained consistent with the prior quarter. And with respect to Q4 we expect sales and gross margins to be affected by a number of additional factors related to our G4 PLATINUM launch, including the impact of reversing our sales return reserves, the impact of our $399 in warranty upgrade programs and our manufacturing scale up activities.
Research and development expense totaled $10.6 million for Q3 of 2012 compared to $8.2 million in Q3 of 2011. The increase primarily resulting from costs associated with our SweetSpot platform, expenses related to our G4 PLATINUM pediatric trial, G4 PLATINUM scale up cost and continued investment in our next generation products. Sequentially, R&D expense remained relatively flat. Selling, general and administrative expenses totaled $15.5 million in Q3 of 2012 compared to $13.2 million during the same quarter in 2011.
The increase primarily related to sales, marketing and information technology costs to support revenue growth. $600,000 of this year-over-year increase is centered in non-cash share based compensations. Sequentially SG&A expenses remained relatively flat. Our net loss for the third quarter of 2012 totaled $17.3 million and included $6.9 million in non-cash expenses centered in share based compensation, depreciation and amortization as well as $4.2 million in non-cash charges and reserves discussed previously.
Absent all of these non-cash charges our net loss for the third quarter of 2012 would have been $6.1 million. Our loss per share for the quarter was $0.25 and again absent our one-time charges our loss per share for the quarter would have been $0.19. We ended the quarter with $53.4 million in cash and marketable securities and had working capital of $55.2 million. One additional note regarding the balance sheet, today we entered into a loan and security agreement with Silicon Valley Bank at Oxford Finance that provides a $15 million revolving line of credit and up to a $20 million term loan to be used for general corporate purposes.
The revolving line of credit is in interest only financing that bears an interest rate equal to the prime rate plus 0.5% and requires repayment of the principle at the maturity date in November of 2015. Under the term loan arrangement, $7 million will be advanced on the funding date and after $13 million and additional funds, will be available upon our request from June 1, 2013 to September 30, 2013.
The term loan, there is a fixed interest rate equal to the 3 year treasury rate at the time of the advance plus 6.94% and requires payments of interest only for the first year and amortized payments of principal and interest thereafter through the maturity date in November 2016. There are no conversions features or warrants associated with this facility.
Now, I'll turn to the business updates. Regarding our product pipeline, I am pleased to report that we had completed our pediatric clinical trial we expect to file a PMA supplement in the U.S. and update our CE mark in the EU to obtain an expanded indication for G4 PLATINUM before year-end.
We're especially excited about the prospects of a pediatric indication that is not only significantly expands the number of endocrinologists we can call in the U.S., we expect to be able to recommend our technology to patients as young as 2 years old which should be a first for CGM.
On the international front, we’ve recently received approval in Australia and we expect approval in Canada and India within the next 6 months. We're actively exploring opportunities in China and Japan and other Asian geographies.
We continue development of the Gen5 system working on an improved applicator combined with a mobile phone interface. We continue to have discussions with the FDA on this front and we believe that DexCom is in a very strong position to become the first Class III medical device to communicate directly to mobile platforms.
We have already seen several early phase mobile based systems and many of the artificial pancreas programs that display our data on a mobile computing platform and remain very encouraged on this front.
Shifting to our integration partnerships, Animas continues to commercialize the Animas Vibe system in Europe and it was made abundantly clear to us by the European Physician Community at the AST in Berlin last month that system is being very well received by patients and physicians in the EU.
With regards to filing for U.S. approval of the Animas Vibe, the work required to modify the system to accommodate G4 PLATINUM in the U.S. has taken slightly longer than expected, but we believe we will complete all development and system testing and be in a position to file early next year.
We are pleased to note that our newest partner, Tandem Diabetes Care reported their first commercial shipments during Q3. We are actively working with Tandem to accelerate our development efforts and are nearing completion of our feasibility assessment of incorporating G4 PLATINUM into the Tandem system.
We are optimistic that feasibility will be successful and hope to be in a position to define our path forward with G4 PLATINUM before the end of the year.
Finally on the Edwards front, work on the second generation in hospital glucose monitoring system is near complete and as Edwards mentioned in their recent earnings call, they expect to obtain a CE mark for the second generation GlucoClear system before the end of 2012.
I would now like to turn the call back over to Terry for some concluding remarks.
