Good morning, everyone. Welcome to our third quarter conference call. I'm joined by Christa Davies, our CFO; and Eric Andersen, our President. As in previous quarters for your reference, we posted a detailed financial presentation on our website. As we begin the call today, we'd like to take a moment to reflect on the ongoing conflict in Israel and Gaza. We condemn violence anywhere that occurs in the world and remain highly concerned about all in harm's way. The safety and well-being of our colleagues and their families is always our top priority. And our team is in constant contact with our leaders in Israel to ensure our colleagues, their families, and our clients have our full support. As we reflect on the quarter, we want to start with a huge thank you to our Aon colleagues around the world for all they do every day to support each other and to support our clients. Turning to financial performance. We delivered strong results in the quarter that contribute to year-to-date progress against our key financial metrics. Organic revenue grew 6% in the quarter was highlighted by double-digit growth in reinsurance solutions and health solutions. Year-to-date 7% organic revenue growth and ongoing operational improvement have contributed to 80 basis points of adjusted operating margin expansion and 10% adjusted operating income growth a strong performance. In our solution lines. Reinsurance solutions delivered another very strong quarter of 11% organic revenue growth with strong growth across Treaty Fac and our Strategy and Technology Group. In addition to delivering a strong quarter, our team is already helping clients prepare for the 2024 renewals. Health solutions also delivered another very strong quarter with 10% organic revenue growth as our team continued to drive strong new and renewal business. We see ongoing focus from clients to address underlying trends impacting their workforce and health care costs such as medical and wage inflation, population health, focus on well-being and overall talent engagement. Within wealth solutions, organic growth of 4% reflected strength in retirement as our teams continue to sell clients with pension risk transfer and regulatory change. Finally, commercial risk organic revenue growth of 4% reflected strong renewals and net new business with strength internationally in EMEA and the Pacific. However, overall organic revenue growth was negatively impacted by the external M&A and IPO markets as we communicated previously. Today we're also excited to announce actions to go further faster on Aon United and we will describe our plan and our restructuring program will accelerate key elements of our strategy. As always, our actions are driven by client need. For our clients the difficult reality of the current world is evident everywhere as they face increasing challenges, understanding, measuring and dealing with risk. Our forthcoming Global Risk Management survey details this trend with input from over 3,000 public and private clients of all sizes across geographies and industries. Trade, Technology, Weather and Workforce Stability are simple forces in today's risk landscape. While each of these forces are individually impacting risk exposures, the increase in connectivity is compounding complexity and presenting new challenges to business leaders. Responding to our clients' increasing and evolving demand, they'll protect and build their business we are advancing a series of actions to further accelerate our Aon United strategy. These actions taken over the next three years, will deliver outcomes that directly address client needs and demand. Specifically, we will improve the quality and availability and analytic tools available to clients, substantially improve their service experience and expand the quality and scope of solutions we bring to them. This work will put our clients in a much stronger position to make better decisions to support their companies. We will accomplish this by delivering on three commitments over the next three years. Internally, we call this 3x3 plan. The three commitments include: first, leveraging our risk capital and unit capital structuring capability to unlock new integrated solutions across our core business, but also address new requirements in client demand. Second, embedding the Aon client leadership model across our enterprise clients in large and middle market segments to further strengthen and expand our client relationships; and third, accelerating Aon business services plan to set a new standard for service delivery and next-generation analytic tools. The benefits of this plan accrue to our colleagues, our clients and our shareholders. Colleagues win with greater capability to serve clients. Today our team is exceptional in their client leadership focus and impact, and this work provides them with next-generation tools and capability to serve clients and to meet increasing client demand. Clients win with better solutions and better service. This work resets client service to a higher standard and provides analytic tools and solutions required to meet demand, and investors win through our greater client relevance continuing margin improvement and sustained double-digit free cash flow growth. And while we could have achieved these benefits over time, we have instead decided back now and accelerate a proven strategy. Let me describe where our team came to this conclusion. The last 10-plus years have demonstrated that a more connected firm is a more capable firm, and the connecting Aon is a done in concept that's accomplished through meaningful structural change, which must be embraced and led by colleagues. It is cultural and only viable as a defining part of our DNA. And even though we remain on a journey, with plenty of distance to travel and opportunity ahead to improve, we have made progress and the results have been meaningful for clients in terms of innovation and support, for colleagues in the form of excitement and engagement currently at an all-time high and for shareholders measured by sustainable value creation including, a 30.8% full year 2022 operating margin compound free cash flow growth of 13% a year from 2010 to 2022 and return on invested capital at year-end 2022 of 30.6%. However, two observations give us conviction that going further faster is a requirement. The first, is increasing client demand. And the second is, our execution confidence based on our proven track record the 3x3 action plan we have defined and the diligent work already underway. Accelerating our plan requires greater upfront investment. And as announced in our press release, we will execute this through a $900 million restructuring program, focused on two areas. First, is on accelerating our Aon Business Services plan by focusing on standardized operations integrating operating platforms and driving product innovation. And the second is, on workforce planning to align skills and capability required to deliver on the digital first opportunity embedded in AI business services as well as workforce changes to strengthen our client-serving capability and risk capital and human capital. This investment will also drive $350 million of cumulative annual run rate savings by year-end 2026, which Christa will describe in more detail. Overall, our team is very excited about the opportunity to accelerate our plans to strengthen client leadership and fortunate that we have the opportunity and options to take this step as a direct result of the work of our colleagues. We continue to expect to drive mid-single-digit or greater organic revenue growth over the course of 2023 and the long-term. We further expect these savings will contribute to ongoing annual margin expansion. And while the program will impact free cash flow in the near-term, over the long-term, we expect to continue to deliver double-digit free cash flow growth driven by operating income and working capital improvements. In summary, our strong year-to-date operational performance, including 7% organic revenue growth, 80 basis points of adjusted operating margin expansion, and 10% adjusted operating income growth, demonstrates strong momentum against our Aon United strategy. It creates the opportunity for us to double down on our strategic commitments around risk capital, human capital, our client leadership model, and Aon Business Services. These steps will enable us to continue to address evolving client demand, improve colleague outcomes, and continue our track record of long-term shareholder value creation. Now, I'd like to turn the call over to Christa for her thoughts on our financial results and long-term outlook. Christa?
