Good afternoon, everyone and thank you for joining us today. 2015 was another excellent year for Cadence, so I am especially pleased to be able to talk to you today about our accomplishments and strategic direction. First let us review our Q4 and 2015 financial highlights. Cadence produced excellent financial results. We delivered revenue of $441 million for Q4 and $1.7 billion for the year, growth of 8% over the prior year. Non-GAAP operating margins was 29% in Q4 and 27% for the year, up from 25% for 2014. Non-GAAP EPS was $0.31 in Q4 and $1.09 for the year, up 16% over the prior year. Execution of our system design enablement strategy drove revenue growth from both semiconductor and system companies in all areas of our business core EDA, IP and system integration. A key part of our strategy is to increase our engagement with new vertical segments and we have notable wins in aviation, automotive, and medical. Demonstrating our constant commitment to innovation, we delivered nine new different shading products. We continue our pioneering work in advanced node technology, with our ecosystem partners, including partnering with Imecs to tape out the first 5-nanometer test chip. And yesterday, we launched our first new product of 2016, the Modus Test Solution. This innovative new technology can reduce SOC test time by up to three times, with no impact on area or routing. Strategy, innovation, execution and customer success are driving strong results for our shareholders and we have momentum going into 2016. Geoff will provide more detail shortly on our 2015 results and our 2016 outlook. Now let us address the environment. Semiconductor business conditions remain challenging, as the industry experienced negative growth in 2015. We remain mindful of ongoing consolidation in our semiconductor customer base. While we do not expect material impact on our business in 2016, consolidation could pose a challenge to industry growth over the next few years. Now, let us talk about some of the product highlights and customer successes in 2015. In digital and signoff, Cadence revenues are nice the digital floor with the release of Innovus for Implementation, Genus for Synthesis and Joules for power estimation. Digital and signoff revenue grew approximately 35% at the accounts we targeted. Adoption of our new digital and signoff portfolio continued in Q4, including a large agreement recently closed with global foundry that supports the newly acquired ASIC team from IBM. Broadcom also renewed investment in Cadence and add the technology to their digital floor, based on total performance evaluation. High silicon adopted Innovus for production DSP designs, enabled them to reduce area by 20% while meeting their frequency goal. And ARM using our full digital floor tape out is 10-nanometer test chip. Overall, we have more than the dozen digital floor wins in 2015. IP is a key component of our overall strategy and is now 12% of our revenue, with growth last year of 17%. We continue to expect IP to be a great business for us, but we are projecting more moderate growth this year as we refine our strategy to focus of sustained, scalable growth. In terms of production, product highlights, Tensilica Vision P5, DSP, our latest vision and imaging processor built strong momentum with key design wins at three application processor vendors in Q4. System design and verification revenue grew 12% in 2015, driven by strength across the product line. Our system development suite attained record revenue in 2015, driven by strong core verification technologies, integrated tightly together to offer a compelling holistic solution. We launched our new Palladium Z1 enterprise emulation platform in November and recognized revenue in Q4. Palladium Z1 now has orders from more than 10 customers, including PMC Sierra, Nvidia and Huawei and the most successful launch of any new Cadence emulator. For custom analog design, Virtuoso is the market leading analog and mix signal design platform. In Q4, we delivered the new Virtuoso Advanced Node Platform for 10-nanometer FinFET Design with initial support for 7-nanometer design. Over 80 customers are now using Virtuoso for advanced node design, including over 25 for 10 and 7-nanometer nodes. Security analysis tools had their best year ever. Our printed circuit board and analysis products won an important competitive replacement with an automotive manufacturer. In summary, 2015 was an excellent year for Cadence. System design enablement is escalating our opportunity beyond EDA. We have tremendous momentum in digital and signed off market segments, and our Palladium Z1 Enterprise Emulation platform is off to a very quick start. There are micro challenges ahead, but also opportunities specific to Cadence. Through innovation and execution we are positioned to build on our success and to further proliferating our solutions with market shipping customers. Now, I would turn the call to Geoff to review financial results and provide our outlook.
