Thank you, Steve and good afternoon everyone. Prior to addressing our second fiscal quarter results I want to echo Steve's thoughts and thank our employees' customers and suppliers for their commitment and partnership during these extraordinary circumstances. Our second fiscal quarter results demonstrated strong performance in both QCT and QTL despite the challenging economic environment.
We delivered total revenues of $5.2 billion and non-GAAP earnings per share of $0.88, which was at the midpoint of the guidance range we provided in February. QTL delivered revenues of $1.1 billion and EBT margin of 63%, both consistent with the midpoint of our guidance. We have now entered into new long-term global patent license agreements with OPPO and Vivo. Our ability to finalize these 5G multimode agreements in a challenging environment reiterates the strength of our IP portfolio and the relationship with these customers.
In the second fiscal quarter, due to the spread of COVID-19, we saw a reduction in 3G, 4G, 5G handset shipments of approximately 21% compared to our prior expectations and on a year-over-year basis. This decline was based on two factors. First, pronounced weakness in China in late January and February, followed by a substantial recovery exiting the quarter. And second a decline in demand in many other regions globally starting in March. This negative impact on QTL was partially offset by a benefit related to updates to previous royalty estimates and favorable mix. In QCT, we delivered revenues of $4.1 billion, MSM shipments of 129 million units and EBT margin of 16%, which was at the midpoint of our guidance. QCT revenues and EBT increased by 13% and 39% sequentially. This reflects the benefit of the first wave of 5G flagship launches, increased content from our RF front end chipset solutions and improved gross margins. In addition, we saw strength in our IoT and networking products due to increased demand for connectivity in this work-from-home environment. Consistent with our expectations, our results included a greater than 50% increase in RF front end revenues on both a sequential and a year-over-year basis. Our total non-GAAP combined R&D and SG&A expenses of $1.7 billion was below the low end of our guidance range including savings in marketing and travel expenses.
With that, I'd like to turn to Global 3G, 4G, 5G device forecast. Given the continued uncertainty around the timing and the pace of the resolution of COVID-19, our third fiscal quarter forecast is based on a planning assumption of approximately 30% reduction in handset shipments relative to our prior expectations. This planning assumption is based on two drivers. First, China sales for the quarter gradually improves from the exit rate of the March quarter; and second, other regions see a recovery starting in June, which is modeled based on the trends we are seeing in China. Our forecast for the first half of 2020 implies a reduction of approximately 10% to the calendar 2020 total device forecast. However, total devices in the second half of 2020 will depend on the speed of the economic recovery.
Turning to 5G device forecast. Launches across all regions remain on track. While we expect some minor changes to the launch timing and sell-through of certain devices, our calendar 2020 estimates remain unchanged at 175 million to 225 million units. Now, let me walk you through our third fiscal quarter financial guidance.
We currently estimate revenues of $4.4 billion to $5.2 billion and non-GAAP earnings per share of $0.60 to $0.80. This guidance includes a greater than $0.30 adverse impact attributable to the reduction in handset shipments due to COVID-19. Given the uncertainty around the time and the scale of the economic recovery, we are providing a wider-than-normal EPS range for the quarter. In QTL, we estimate third fiscal quarter revenues of $750 million to $950 million and EBT margin of 50% to 56%. This guidance reflects a normalized run rate of $1 billion to $1.2 billion adjusted for the impact of lower handset shipments due to COVID-19. As a reminder, our third fiscal quarter forecast for QTL does not include revenues from Huawei. In QCT, we estimate revenues of $3.6 billion to $4.2 billion, MSM shipments of 125 million to 145 million units and EBT margins of 14% to 16%.
Our guidance reflects the latest demand signals from our customers as they contemplate the global impact on device sales and reconcile their supply chains to the lower sell-through. We expect revenue per MSM to decrease sequentially, reflecting the normal seasonal mix shift, following the 5G flagship handset launches in our second fiscal quarter. We anticipate third fiscal quarter non-GAAP combined R&D and SG&A expenses to be approximately flat on a sequential basis. We returned approximately $2.3 billion to stockholders during the second fiscal quarter, including $705 million in dividends and $1.6 billion in stock repurchases. Additionally, we announced a 5% increase to our quarterly dividend to $0.65 per share.
Given the current economic landscape, we have performed scenario planning with a focus on liquidity and we will continue to evaluate our cash flow and capital policy as the situation evolves. In these challenging times, we are glad to have a strong balance sheet, liquidity position and debt rating. Looking forward, our top priority is the health and safety of our employees, and the communities in which we operate. Our business strategy remains unchanged. We remain confident in the long-term growth opportunities, including 5G adoption, RF front-end content capture, and the expansion of our technologies and adjacent platforms. Thank you. And I'll now turn the call back to Mauricio.
