Thank you, Gary, and thanks to all of you for joining us today. I'll start by reviewing our Q1 highlights. Solid momentum continued in the first quarter with revenue and margins meeting our expectations. Total company organic revenues rose 6%, driven by 6% recurring revenue growth. The Big 3 segments grew 7% organically. We continue to see strong momentum from many areas in our business. Westlaw Precision's fast start continues with more than 1,400 sales to date. The SurePrep acquisition is going well and remains positioned to deliver revenue growth in excess of 20%. Our international businesses had a strong quarter with Latin America, Asia and emerging markets and Canada all delivering double-digit organic growth and many of our other products remain double-digit growers, including Confirmation, HighQ and Practical Law. Despite this optimism, the macroeconomic backdrop remains highly uncertain, and we continue to closely monitor our customer sales activity. The sales cycle lengthening that we have seen in recent quarters continues and has broadened out slightly but not enough to impact our 2023 outlook. We are maintaining our full year 2023 outlook, including for organic revenue growth and adjusted EBITDA margins. The one adjustment is to lower total revenue growth to incorporate the pending sale of the majority stake in Elite, which we expect to close in the second quarter. Mike will discuss this in more detail later in the call. Our capital capacity and liquidity remain the key asset that we are focused on deploying to create shareholder value, and we made good progress on this during the first quarter. We repurchased approximately $700 million of our shares, completing the $2 billion share buyback program we announced in June 2022. We closed on the $500 million acquisition of SurePrep in early January, and we sold approximately 24.5 million shares of London Stock Exchange Group, or LSEG, across two transactions in the quarter, generating gross proceeds of $2.3 billion. Looking forward, we remain committed to a balanced capital allocation approach that includes annual dividend growth, strategic M&A and returning capital to shareholders. As we announced last quarter, we plan to execute a $2.2 billion return of capital transaction with the concurrent share consolidation in June 2023. We also continue to assess inorganic opportunities and are optimistic we will be able to execute additional strategic transactions in the next 12 to 18 months. Now, to the results for the quarter; first quarter organic revenues grew 6%. Organic recurring revenue also grew 6% with transactional revenue growing 11%. Reported revenue grew 4% with currency and recent divestitures each a 1% drag. Adjusted EBITDA increased to $677 million, reflecting a 300 basis point margin improvement to 38.8%. Adjusted earnings per share grew 24% from the prior year period to $0.82. Turning to the first quarter results by segment, the Big 3 businesses achieved organic revenue growth of 7%. Legal organic revenues grew 5% with recurring growth of 6% and slightly lower transactional revenue. Demand for our key offerings remains healthy, led by Westlaw, Practical Law and HighQ. We continue to expect growth to reaccelerate to 6% in the second half of 2023 with revenue up 8%. Recurring and transactional revenue grew 7% and 11%, respectively. Practical Law, Confirmation, CLEAR and HighQ were key drivers. Tax & Accounting organic revenue rose 11% with recurring revenue up 6% and transactional revenue up 19%, boosted by the SurePrep acquisition which is predominantly transactional revenue. Our Latin America operations, Confirmation and SurePrep, each contributed meaningfully to growth. As expected, Reuters News organic revenues rose 1%. A lower price increase than in 2022 on the news agreement with the data and analytics business of LSEG, seasonally light events calendar and a weaker digital revenue impacted growth. Lastly, Global Print organic revenues were flat year-over-year, again better than expected, due to improved retention, better third-party print revenue and timing benefits that we expect to normalize in the remainder of 2023. In summary, we're pleased with our results and the solid momentum in the business. Now let me spend a few minutes discussing artificial intelligence at TR. Generative AI and large language models, or LLMs, have created a lot of buzz in recent months, and we are very excited about the potential to harness this emerging technology across our businesses. Before I go into more detail about our generative AI approach and why we believe we are well positioned, let me start with three key takeaways. First, we have a long history as a leader in leveraging AI and machine learning. Second, we see a clear path to enhance value for our customers across legal, tax and risk markets by integrating generative AI into our offerings. And third, generative AI provides us with an opportunity to extend our leadership in legal research more deeply into the fast-growing sub-segment of workflow software as they will become increasingly indistinguishable. On the first point, Thomson Reuters has long been a leader in leveraging new technologies, including machine learning and AI. In fact, AI already plays a critical role at TR today as it is embedded in how we create, enhance, connect and deliver trusted information and software to our customers. In fact, in the 1990s, we were amongst the earliest commercial applications for natural language processing search. And since then, we have leveraged increasingly sophisticated AI and ML capabilities to improve search and expand analytics through a series of product advances, including Westlaw Next, Westlaw Edge, Practical Law Dynamic, and most recently, Westlaw Precision. Acquisitions have also bolstered our AI capabilities and talent. The ThoughtTrace purchased last spring bought leading AI contract analysis capabilities that power our legal document intelligence offerings. And the SurePrep acquisition earlier this year bought AI-driven automated document ingestion capabilities that provide meaningful workflow automation benefits to our customers in our Tax business. These advancements, coupled with our proprietary content and editorial expertise, deliver comprehensive, accurate and trusted insights that power the performance of professionals in the legal, tax, risk and compliance fields. Shifting to generative AI, we see great promise in this emerging technology, which we believe has applications across many of our key offerings. We have been working with and testing large language models for a number of years, and we expect to incorporate these capabilities into several key franchises in the second half of 2023. For our research offerings including Westlaw, Practical Law and Checkpoint, we will leverage large language models to offer chat-based conversational interfaces that will simplify search and make it easier for users to find the trusted content they need. We believe this can offer meaningful time savings to our customers, in addition to a significantly improved user experience. We also see applications of generative AI to enhance our workflow solutions with a more conversational experience and intuitive automation. For example, document drafting is one opportunity that we are pursuing. And we see generative AI driving an acceleration of integration between our research and our workflow offerings. This has long been a focus of ours, and we believe generative AI will help us deliver this vision to the market. For example, consider a future legal drafting tool that automatically leverages Practical Law to incorporate valid legal clauses and Westlaw for key citations. Given our leadership in legal research, we see this blended insights and workflow software has a significant opportunity for Thomson Reuters. While the technology showed tremendous potential, it still has big issues with accuracy. And for our customers pursuing high stakes litigation needing to understand the latest regulations and statutes or involved with tax determination, accuracy is of critical importance. As a result, we are working to leverage our existing strengths and unique content to improve upon these accuracy issues while delivering the benefits of generative AI. At this point, we bring several key advantages that give us confidence we can be a leader in leveraging generative AI for the benefit of our customers. This includes the breadth of our proprietary content and legal and tax research expertise, which we can bring to bear to train and improve AI models. In addition, our advanced search capabilities and significant data science and AI software engineering talent through TR Labs are key advantages. Given that our key solutions are deeply embedded into our customers' workflows, we also bring a strong starting point from which to incorporate new capabilities. In our early testing, using Westlaw content and search capabilities along with large language models yielded significant accuracy benefits versus LLMs alone, as we would expect. We are focused on further driving AI's leadership and plan to invest more than $100 million per year in the next few years on further integrating AI capabilities into our offerings. We've also made several key investments in AI through our TR Ventures Fund, and we're on track to incorporate generative AI capabilities into Westlaw Precision and Practical Law dynamic in the second half of this year. So in summary, while we remain vigilant about the challenges posed by technological change, our history of leveraging cutting-edge technology and significant competitive advantages we possess and our focus and heavy investment on further harnessing AI leave us excited and confident of our ability to lead the way forward for the benefit of our customers and our shareholders. And now let me turn it over to Mike.
