I would now like to hand the conference over to Mr. Andy Blanchard, Vice President of Investor Relations. Please go ahead, sir. Andrew Blanchard -- Vice President, Investor Relations Thank you, Sharon. Good morning everyone and welcome to our discussion of Teradyne's most recent financial results. I'm joined for our discussion this morning by Teradyne's CEO Mark Jagiela and CFO Sanjay Mehta. Following our opening remarks, we will provide details of our performance for 2020's 4th quarter and full year along with our outlook for the first quarter of 2021. The press release containing our results was issued last evening. We are providing slides on the Investor page of the website that may be helpful to you in following the discussion. Replays of this call will be available via the same page after the call ends. The matters that we discuss today will include forward-looking statements that involve risk factors that could cause Teradyne's results to differ materially from management's current expectations. We encourage you to review the Safe Harbor statement contained in the earnings release as well as our most recent SEC filings. Additionally, those forward-looking statements are made as of today and we take no obligation to update them as a result of developments occurring after this call. During today's call, we'll make reference to non-GAAP financial measures. We've posted additional information concerning these non-GAAP financial measures including reconciliation to the most directly comparable GAAP financial measure, where available on the Investor page of our website. Looking ahead, between now and our next earnings call, Teradyne will be participating in technology or industrial focused investor conferences hosted by Goldman Sachs, City, and Susquehanna.
