Good morning, and thank you for joining us today. In the first quarter, AB benefited from strong global equity market returns complemented by robust double-digit organic fixed income flows and 8% annualized growth in alternatives to multi-asset, more than offsetting equity outflows. AB's balance and diversification across asset classes and geographies coupled with broad global distribution capabilities enabled us to continue to drive market share gains in key areas. Retail led the way, driven by municipal SMA and strong cross broader fixed income flows. On April 1st, we closed the Bernstein Research joint venture with Societe Generale, improving our future profit margin profile, while using the proceeds of $304 million to pay down debt before quarter end, providing flexibility to invest in the future. Now let's get into the specifics, starting with a firm wide overview on Slide 4. First quarter gross sales were $32.6 billion up $7 billion or 27% from the year ago period. Firmwide active net inflows were $3.7 billion or 2.3% organic growth. Quarter end assets under management of $759 billion increased by 12% year-over-year and 5% from the end of the fourth quarter. And first quarter average assets under management were up 11% year-over-year and 8% sequentially. Slide 5 shows our quarterly flow trend by channel. Firmwide, first quarter net inflows were $500 million. Strong retail gross sales of $23.8 billion increased 42% year-over-year and 13% sequentially, driven by both fixed income and equities. Net inflows were $4.2 billion or 6% annualized organic as we continued to gain share in fixed income, up 23% annualized organically. Our institutional channel had gross sales of $3.3 billion up 12% from both prior periods. Net outflows of $4.2 billion included a $3 billion low fee passive partial redemption. In Private Wealth, gross sales were strong at $5.5 billion with net inflows of $500 million led by Muni, our proprietary direct indexing fund and ETFs. Investment performance is shown on Slide 6. Starting with fixed income. Government bond returns ended the first quarter flat, while most credit risk assets outperformed in the quarter. Government bond returns reflected volatility associated with the magnitude and timing for when central banks would begin to cut rates, falling early in the quarter and subsequently rallying in mid-March when those views began to change. Meanwhile, corporates came to market with record new issuance and investors locked in higher yields. AB fixed income performance remains strong with 91% of assets outperforming over the one year period and 71% over both three and five year periods. This performance translated to double-digit annualized organic growth across our fixed income asset base this quarter, including some standout performances in retail. Turning to equities. Global equity markets posted strong quarterly returns with the S&P 500 up 10.6%, reflecting a resilient U.S. economy, ongoing enthusiasm around artificial intelligence and a widely held outlook for monetary easing, albeit at a slower pace than initially expected. We were encouraged by evidence of a more fundamentally driven environment as exemplified by some dispersion in performance amidst the Magnificent 7. Our investment performance showed steady improvement as several large AUM strategies outperformed benchmarks in the first quarter. 40% of equity assets outperformed over the one year period, while 50% outperformed over both the three and five year periods. We continue to experience outflows in equities. Client rebalancing within their allocations, a shift to fixed income products given the higher rate environment, and specific strategies in which underperformance led to redemptions contributed to the negative flows in the quarter. That said, we received an upgrade from a global consultancy for U.S. Sustainable Thematic, an example of that strong long-term performance is being recognized. We're seeing some signs of renewed in U.S. value for which we have several competitive strategies as exemplified by fundings of the $330 million mid-cap value mandate during the quarter. Relative to peers, 54%, 71%, and 68% of our equity assets outperformed the MorningStar peer group over the one, three and five year periods respectively. Now I'll review our client channels, beginning with retail on Slide 7. Gross sales and net inflows both reached the highest level in nine quarters, approaching record 2021 levels. The redemption rate improved sequentially to 27% from 30%, while ticking up slightly versus prior year. Net inflows of $4.2 billion reflected strong geographic breadth and demand for income from Asian investors despite resurgent rates volatility in the quarter. Taxable fixed income, we grew organically at a 25% annualized rate with net inflows of $4 billion marking the highest quarterly gain, since 2019. Sustained inflows into American income and money markets were supplemented by client engagement and global high yield. Muni's posted record net inflows $2.3 billion 28% annualized organic growth rate. Active equity outflows reflected sequential improvement as redemption subsided, while performance rebounded. U.S. large cap growth posted net inflows in both Japan and the United States. You'll hear today from Mark Gessner, our Head of US Retail, who will walk you through our remarkable progress and growth outlook in the US Retail channel. Turning to institutional on Slide 8. First quarter gross sales were $3.3 billion up 12% versus prior periods. Outflows of $4.2 billion were concentrated in equities, including a $3 billion low fee passive equity partial redemption. Flows rebolstered by ABCarVal, which saw a $780 million COL and $315 million in residential mortgages, but latter funded by equitable. Alternative multi asset flows are now positive for 13 of the last 16 quarters. Representing 35% of our channel AUM, up from 21% three years ago. Alts multi-asset has grown at a 20% CAGR, lifting our channel fee rate by 13% over this period. The ABCarVal acquisition is reflected during this period. Our pipeline was $11.5 billion at quarter end, down $500 million sequentially. First quarter fundings included $330 million in U.S. mid value and $135 million in U.S. low vol. Notable pipeline additions include $500 million through AB Private Credit Investors' new NAV Lending strategy funded by equitable and $500 million for systematic U.S. investment grade. Equitable's initial $10 billion private markets program is now over 95% deployed and we expect it will be completed in the first half of this year. The second $10 billion is expected to commence thereafter and extend over the next few years. Moving to Private Wealth on Slide 9. First quarter gross sales of $5.5 billion resulted in net inflows of $500 million. We posted strong sales in our proprietary direct indexing strategy, now $4.6 billion in AUM, municipals and ETFs. Advisor productivity remains solid, and we continue to invest with FA headcount on track for mid-single digit growth in 2024, including internal promotions, a key part of our strategy. We have a diverse slate of private alternatives launches slated to ramp beginning in the second quarter, including our Evergreen Strategies, 2 ABCarVal Strategies and select external partners. I'll finish with our business overview with the sell side on Slide 10. With the close of the joint venture on April 1, this is the last time we'll be reporting separately on Bernstein Research. First quarter Bernstein Research revenues of $96 million were down 4% over both prior periods. We saw modest improvement in Asia though global trading activity remains subdued. The close of the joint venture was bittersweet, the culmination of a great deal of time and effort expended by our many talented colleagues. We're proud of Bernstein's high quality global research effort built over the years, and we are excited for Bernstein's future under Societe Generale's majority ownership with the opportunity to leverage SocGen's experience in equity capital markets, derivatives and prime brokerage. Jackie will walk through the specifics on modeling for the financial impact shortly, which is summarized on the accompanying side. I'll conclude by reviewing the status of our strategic initiatives on Slide 11. Performance of fixed income was strong for all periods, while equities improved steadily, though much progress remains. We grew organically, driven by 2% active organic growth, led by Retail, which posted outstanding 25% plus annualized growth in both taxable and municipal fixed income. We continue to grow through differentiated products, including our ETFs, now up to $2.6 billion in AUM, private markets at $63 billion up 9% year-over-year and tax efficient offerings including municipals. First quarter adjusted operating income rose 12% year-over-year, operating margin exceeded 30%, up 160 basis points and earnings and unitholder distributions of $0.73 per unit were up 11%. Now I'm pleased to turn the call over to Mark Gessner to discuss the growth in our U.S. retail platform. Mark?
