Good morning and thank you for joining us today. In the third quarter, equity and fixed income markets pulled back from gains earlier in the year as yields remained volatile, moving higher throughout the quarter and reaching levels last seen pre-global financial crisis. While retail investors continue to sit on the sidelines favoring cash assets offering more than 5%, we believe that flows will eventually migrate back to bonds to supplement equity allocations as investors take advantage of higher yields and position portfolios to beat inflation. Despite these industry-wide headwinds, AB posted organic growth in several key services as we executed on our strategic initiatives. We continue to gain market share in retail, driven by organic growth in both taxable and muni bonds. Our municipal SMA platform reached $20 billion in AUM, growing organically in 12 of the last 13 quarters and having more than doubled over the last five years. Active equity grew 7% annualized and institutional. Our active ETF platform celebrated its one-year anniversary, now at just under $1 billion in assets under management. And we saw net inflows into private markets led by AB CarVal's Clean Energy Platform. Let's get into the specifics, starting with a firm-wide overview on slide four. Gross sales were $25.2 billion, up $5.4 billion or 27% from the year-ago period, and up $2.8 billion or 13% sequentially. Firm-wide active net flows were almost flat, down $100 million. Quarter-end assets under management of $669 billion increased by 9% year-over-year, but were down 3% sequentially. While average assets under management of $690 billion was up 5% year-over-year and up 2% sequentially. Slide five shows our quarterly flow trend by channel. Firm-wide third-quarter net outflows were $1.9 billion. Retail gross sales of $16.9 billion increased 22% year-over-year and 3% sequentially. Net inflows were $1.6 billion, reflecting continued strong demand for taxable and municipal fixed income, up 7% and 14% annualized organically, respectively. Our institutional channel had gross sales of $4.3 billion, improved from both prior quarters. Net outflows were $3.5 billion as taxable fixed income and passive equity outflows more than offset $1 billion of net inflows from active equity. In private wealth, gross sales were healthy at $4 billion, driven by money market funds. Net flows were flat as redemptions normalized as compared with lighter redemptions in the third quarter of last year. On a year-to-date basis, two of our three channels are flowing positive, with retail and private wealth generating net inflows of $2.5 billion and $1.7 billion, respectively. Investment performance is shown on slide six, starting with fixed income. During the quarter, developed market government bond yields rose and overall returns fell in all major markets. Longer maturity government bond yields spiked in late September after the Fed released its updated quarterly Dot Plot that showed U.S. interest rates will likely be higher for longer than anticipated. High-yield bonds had positive returns of 85 basis points, materially outperforming government bonds in the Eurozone and the U.S. In the face of this rate volatility, AB's fixed income performance remained strong, with 73% of our assets outperforming over the one-year period, 74% over the three-year, and 62% over the five-year. Despite investors remaining cautious in adding duration, we experienced $900 million of net inflows into our American Income Fund, now totaling $4 billion year-to-date. We celebrated our 30th Anniversary of American income in July with campaigns around the world. Turning to equities, as bond yields rose, global equity sold off following a rally in the first half of 2023. The S&P 500 declined 3.3%, bringing year-to-date returns to 13.1% in U.S. dollar terms. Growth stocks sold off most as the focus turned back to macroeconomic uncertainties from the excitement over the potential for artificial intelligence early in the year, with value and minimum volatility stocks falling less. Our equity performance continued to lag mega-cap tilted benchmarks, with 32% of equity assets outperforming over the one-year period. Our three-year and five-year performance remained stable at 49% and 50% of assets outperforming respectively. Importantly, we continue to outperform the Morningstar Peer Group with 64% and 69% of our equity assets outperforming over the three and five year periods, respectively. Now, I'll review our client channels, beginning with retail on slide seven. Gross sales increased versus both prior periods, while the redemption rate improved at 23% versus 27% last quarter and 30% a year ago, contributing to net inflows of $1.6 billion. For the 12th time in the last 14 quarters, we saw strong organic growth rates in U.S. retail, up 12% annualized for both the third quarter and year-to-date. In taxable, we saw strong growth in money funds and continued inflows in American income. Muni sales inflows also continued to be robust, with net inflows once again of $1 billion or 14% annualized organic growth. The breadth of our muni SMA platform is more expansive than ever and reflects the success of multiple customized strategy wins at major brokerage firms, as well as turnkey asset management programs on-boarding more AB SMA products. We expect to roll out additional duration customizations on a major brokerage platform before year-end. Our active positioning, enhanced customization features, lower fees, and technology edge which contributes to generating Alpha, are the main selling points of our muni SMA strategies today. Our new muni SMA Service Center is designed to enhance our overall SMA service model in U.S. retail by providing our sales staff and financial advisor partners with easy access to important client deliverables. As shown on the bottom right, we posted top flow rankings across asset classes, ranking in the top 5% of U.S. retail flows in equities and munis and top 3% for cross-border flows for fixed income. Finally, one year into our active ETF program, we're pleased to be just $20 million shy of $1 billion, a level only one in five active ETF sponsors attained in their first year. We have additional fixed income launches scheduled later this year following equity launches earlier in 2023. Turning to institutional on slide eight, third quarter gross sales were $4.3 billion, up $2.4 billion from last year and up $2.8 billion sequentially. Net outflows were $3.5 billion, concentrated in fixed income and passive equities. Higher interest rates drove repositioning by several clients, exemplified by a large insurance client for whom rising interest rates created hedge volatility, requiring them to post collateral and reduce their gross positioning. Our pipeline was $12.5 billion at quarter end, down $1.9 billion sequentially. We experienced fundings of $2.5 billion, including $1.3 billion U.S. large cap growth mandate and over $200 million in AB CarVal's Clean Energy Fund. We added $300 million mandates for both tax-aware fixed income and low volatility high yield, complemented by active equity wins and sustainable global thematic in China A-Share's value. Equitable's initial $10 billion private markets program announced in mid-2021 is now 80% deployed and we are progressing on discussions for future opportunities, including for example, NAV lending. Reflecting the success of our growing insurance focus, I'm pleased to share that we recently won two 2023 Insurance Asset Risk Americas Awards, Alternative Manager of the Year and Asset Manager Investment Team of the Year. While conditions for private alternatives fundraising remain more challenging, we're executing on three focus areas. The first closed for European Cred Secured Income Fund, Secured Income Fund Plus, targeting overall fund raise of $500 million, focused especially on investors in Europe and select Asian markets. AB CarVal's credit value fund six fund raise in all global regions targeted at $2.5 billion and continuing to raise capital in our direct lending evergreen funds with particular focus on our AB private credit investors business. Moving to private wealth on slide nine. Third quarter gross sales remained healthy at $4 billion, down 2% year-over-year and down 9% sequentially. We continue to experience strong sales and money market funds, municipals and proprietary passive equity tax harvesting strategy, which grew to $3.1 billion, hosting strong annualized organic growth of 31%. Third quarter net flows were flat, though up on a year-to-date basis, 2.2% annualized organically and on track for a third straight year for organic growth. Over the last 12 months, AUM growth from business sales has outpaced the industry as measured by M&A volumes and pre-transaction planning pipeline remains solid. Year-to-date alternative capital raises were $1.6 billion with third quarter sales focused on private credit and secondaries. I'll finish our business overview with the sell side on slide 10. Third quarter Bernstein Research revenues of $94 million increased 3% year-over-year and 2% sequentially. We experienced modest growth in research payments versus the prior periods. Industry-wide global institutional equity trading volumes remain constrained with the exception of improvement in Japan equities. We launched coverage of two new sectors this past quarter and our 20th annual Pan-European Strategic Decisions Conference was a resounding success with over 400 clients attending. Our joint venture with Societe Generale remains on track to close in the first half of 2024. We anticipate disclosing further financial details closer to that time. I'll conclude by reviewing the status of our strategic initiatives on slide 11. Performance and fixed income remain strong, while equities continue to lag versus concentrated capitalization weighted benchmarks. Active net inflows in the third quarter were nearly flat despite a challenging backdrop. Third quarter results were led by retail which posted 10% annualized organic growth in fixed income with growth in both taxable and municipal. Institutional active equity annualized growth is 7% more than offset by fixed income net outflows, reflecting a higher yield environment. Year-to-date, two of our three channels, retail and private wealth, have posted organic growth. Our muni SMA platform reached $20 billion in assets under management having more than doubled over the last five years and up 9% annualized organically in the quarter. Adjusted financial comparisons improved over the prior year period with operating income up 13%, operating margin of 28% up 220 basis points and earnings and unit holder distributions of $0.65 per unit up 2%. Lastly, we've made progress in our CFO search, which is in its final phase and should be concluded in the near term. Now, I'll turn the call over to Bill Siemers to discuss financials. Bill?
