Thank you, Ravi and good afternoon everyone. I am very excited to join Cognizant, and would like to thank the entire organization for such a warm welcome. I would also like to thank, Jan, for helping me in making the onboarding experience so seamless. I have always admired Cognizant's growth mindset, client centricity and the entrepreneurial culture. While it has only been two months since I joined, the energy and passion across the organization are apparent. I have also had the opportunity to participate in our global sales kickoff events in January. This has further strengthened my conviction in Cognizant's capability and our market opportunity. I'm excited to partner with Ravi and the entire leadership team, to build on the progress we have made in 2023, as we strive to reach our full growth potential. In doing so, I believe there is a tremendous opportunity, to create long term sustainable value for our associates, clients and shareholders. With that, let's turn to our fourth quarter and full year revenue results. Fourth quarter revenue was $4.8 billion, representing a decline of 1.7% year-over-year or a decline of 2.4% in constant currency. Year-over-year performance includes approximately 90 basis points of growth from our acquisitions. This led to full year revenue of $19.4 billion, which declined 0.4% year-over-year or 0.3% in constant currency. Year-over-year growth includes approximately 110 basis points of growth from acquisitions. Ravi discussed Financial Services and Health Services, which declined 6.6% and 2.7% year-over-year in constant currency, respectively. So I will quickly comment on our other two segments. Products and Resources revenue was roughly flat year-over-year in constant currency, which included contribution from recently completed acquisitions and the ramp of new business. This helped offset the macro-driven discretionary spending pressure. We saw relatively better performance in North America, particularly among auto, utility and travel and hospitality clients. Communication, media and technology revenue increased 2% in constant currency. The growth reflected the benefit from recently completed acquisitions and the ramp of new bookings. Now, moving on to margins. During the quarter, we incurred approximately $40 million of costs related to our NextGen program. This negatively impacted our GAAP operating margin by approximately 90 basis points. Excluding this impact, adjusted operating margin was 16.1%. Year-over-year, margin included savings from our NextGen program and tailwinds from the depreciation of the Indian rupee. This helped partially offset increased compensation costs. As a reminder, the prior year period also included a negative impact from a noncash impairment charge, related to a Health Sciences customer. Our GAAP tax rate in the quarter was 26%, adjusted tax rate in the quarter was 25.4%. Q4 diluted GAAP EPS was 1.11, which is $1.11 and Q4 adjusted EPS was $1.18. Now, we turn to the balance sheet. We ended the quarter with cash and short term investments of $2.6 billion or net cash of $2 billion. DSO of 77 days was flat sequentially and increased three days year-over-year, driven by our business mix. Free cash flow in Q4 was $659 million which brings full year 2023 free cash flow to $2 billion or approximately 95% of the net income. This was slightly ahead of our expectations. During the quarter, we repurchased over 4 million shares for $313 million and returned $146 million to shareholders through our regular dividend. For the full year, we returned about $1.7 billion to shareholders, including $1.1 billion through share repurchases and $591 million through our regular dividend. As of December 31, we had $1.8 billion remaining under our share repurchase authorization. Turning to our forward outlook. For the first quarter, we expect revenue in the range of $4.68 billion to $4.76 billion, representing a year-over-year decline of 2.7% to 1.2% or a decline of 3% to 1.5% in constant currency. Our guidance assumes currency will have a positive impact of approximately 30 basis points. For the full year, we expect revenue to be in the range of $19 billion to $19.8 billion, which is a decline of 1.8% to growth of 2.2% year-over-year or a decline of 2% to growth of 2% in constant currency. Inorganic contribution is expected to be up to 100 basis points, and we anticipate approximately 20 basis points positive impact for the year from the currency. Our NextGen program remained on track this quarter, and we still expect to incur total cost of approximately $300 million. This includes $229 million incurred in 2023, and our expectation for an additional $70 million in 2024. There are no changes to our savings assumption from NextGen, and we still intend to reinvest the majority of the savings in the growth opportunity in 2024 and beyond. Moving on to adjusted margins. We are pleased with the strong finish to 2023, which allowed us to deliver a full year adjusted operating margin of 15.1% versus our guidance of 14.7%. In 2024, we continue to expect 20 to 40 basis points of operating margin expansion. This represents an adjusted operating margin range of 15.3% to 15.5%. We remain focused on driving further efficiency in our business model through improved utilization, increased operational discipline and automation of tools and processes. We are also introducing guidance for net interest income versus our prior practice of providing gross interest income. For the full year, we anticipate net interest income of approximately $40 million. Our expectation for the full year adjusted tax rate is 24% to 25%. For the full year, we expect free cash flow will represent about 80% of net income. This includes an anticipated negative impact of approximately $360 million because of a ruling on January 8 in India relating to a previously disclosed 2016 tax matter in connection with share repurchase transactions, undertaken by our Indian subsidiary. The ruling required Cognizant to deposit the funds with India tax authorities to proceed with our appeals process. The funds deposited with tax authority were previously held in bank deposit under lien. And as of December 31 were presented on our balance sheet under long term investments. The outflow will negatively impact our operating cash flow, but will not impact the cash and cash equivalent amounts on the balance sheet, and therefore, we do not anticipate any impact to our capital allocation priorities. Final amounts refunded to Cognizant or due toward tax authorities will be determined at the end of the appeals process. We continue to believe that we have complied with all tax regulations applicable to this matter in accordance with the law and intend to vigorously defend our position. Moving on to capital allocation. We expect to return over $1 billion to shareholders in 2024, including at least $400 million through share repurchases and $600 million through regular dividends. We will also continue to pursue acquisition opportunities aligned with our strategy. For the full year, we therefore, expect to deploy more than 100% of free cash flow, given the negative impact of the free cash flow from the aforementioned additional deposit with the India tax authorities. Based on our anticipated share repurchases, our guidance for shares outstanding is approximately $497 million. This leads to our full year adjusted earnings per share guidance of $4.5 to $4.68. With that, we'll be open to take the questions.
