Thank you, Robert. I am extremely proud to be a part of a great team of people working with the best agents in the industry. Before getting into the financials, I wanted to give you some details on our operations. In the fourth quarter, we processed 40,621 transactions, a decline of 4.9% from a year ago, which compares favorably to the 9.2% decline in transactions for the entire residential real estate market in the fourth quarter, as reported by the National Association of Real Estate. Our market share for Q4 2023 was 4.41%, up nine basis points year over year versus Q4 2022, and up 10 basis points sequentially from Q3 2023. For Q4 2023, our average number of principal agents increased to 14,689, which is an increase of 7.7% year over year and up 4.5% quarter over quarter. In the fourth quarter, we managed out approximately 50 principal agents and 400 total agents, each with an average GCI of less than $10,000, which had the additional benefit of freeing up resources for the rest of our producing agents. As Robert mentioned, we are focused on bringing in successful agents that produce results. Since the elimination of cash and equity sign-on incentives in August of 2022, we have recruited more than 2,000 agents. Agent retention remains high as our principal agent quarterly retention was 97%, a number we have consistently reached since becoming a public company in April 2021. Our title and escrow businesses generated positive adjusted EBITDA in 2023, and attach rates continue to increase, benefiting from the successful launch of T&E integration in the Compass platform in Southern California. We have completed the rollout of the T&E integration in Philadelphia, Southern New Jersey, and the Washington, D.C. area, including Maryland and Virginia, as planned. By the end of Q3, we plan to roll out this integration feature to all the markets where we currently offer title and escrow services, including in our newest title and escrow market, Florida. One of the ways we will look to grow EBITDA margin in the business will be through integrated services such as title and escrow and mortgage. We will continue to look for opportunities like our recent acquisition of Attorneys Key Title in Florida. Let me now turn to our fourth quarter and full year financial results and our guidance for the first quarter. Our fourth quarter revenue was $1.1 billion, which was at the low end of our guidance range of $1.1 billion to $1.2 billion, reflecting continued pressure from mortgage rates since the time we put out our Q4 guidance back in November. Our Q4 revenue is down 1% for the year ago period, and gross transaction value was $41.8 billion in the fourth quarter, a decline of 1.6% from a year ago, reflecting a 4.9% reduction in total transactions, partly offset by an increase in average selling price. Our non-GAAP commission expense as a percent of revenue is 81.7%, an increase of nine basis points from Q4 of last year, reflecting the impact of the agent equity program on the year ago period. As a reminder, 2022 was the last year we offered the agent equity program, which allowed our agents to exchange a portion of their cash commission for equity. Page 15 of the Q4 investor deck includes additional details on the agent equity program's impact on the commission line in the prior year periods. Q4 2023 is the last quarter you will see this differential as we have now lapped the sunset of the agent equity program. For the full year of 2023, our commission rate as a percent of revenue improved by four basis points compared to 2022, which was masked by a drag of about 10 basis points due to 2023 brokerage acquisitions that were made in markets with lower splits than our overall average brokerage split. So adjusting for this M&A drag, our true commission rate improvement improved by 14 basis points. As Robert mentioned earlier, we have made meaningful progress in improving agent economics, and during 2023, we will prioritize reducing agent cash incentives, such as marketing incentives. Since these incentives are included in the sales and marketing line as a component of OpEx, we have extracted them to demonstrate, and they accounted for an additional 43 basis points of improved economics for the full year of 2023 compared to 2022, or an aggregate improvement of 57 basis points in overall agent economics. Our total non-GAAP operating expense, excluding commissions and other related expenses, were $224 million for the fourth quarter, which is an annualized basis. As we've talked about previously, many of our non-commission-based operating expenses are somewhat fixed in nature and have historically increased sequentially from quarter to quarter as opposed to varying in line with revenue. However, due to our cost reduction initiatives implemented over the past 18 months, the $224 million of OpEx for the fourth quarter reflects a $142 million reduction from OpEx of $366 million in the second quarter of last year, which was the quarter we began our cost reduction initiatives. And this reflects a decline of over $570 million on an annualized basis. Our management team remains disciplined and focused on operating expenses, and as Robert mentioned, we are focused on maintaining our operating discipline that allows us to sustain our new cost base. As a reference point, the non-GAAP operating expenses we refer to include the expense categories of sales and marketing, operations and support, R&D, and G&A, and exclude stock-based compensation expense and other expenses that are excluded from adjusted EBITDA. We've included tables on page 13 and 14 in our Q4 investor deck that reconcile these amounts to our GAAP operating expenses. Our adjusted EBITDA for the fourth quarter was a negative $23.7 million, within our guidance range of negative $20 million to negative $35 million. Our GAAP net loss for the fourth quarter was $83.7 million, compared to a loss of $158.1 million in the same period a year ago, and includes non-cash charges such as $36 million of non-cash stock-based compensation expense and $22 million of depreciation and amortization expense. Free cash flow during the fourth quarter was negative $41 million, which compares favorably to negative $131 million of free cash flow in the year-ago quarter, driven primarily by the improvement in adjusted EBITDA, lower capital expenditures, and other favorable changes in working capital. In particular, capital expenditures were just $2 million in the current quarter, compared to $13 million a year ago, driven by our cost-cutting measures and the intentional slowing of expansion to new markets and new offices. We have meaningfully improved our free cash flow position compared to last year. When comparing the full year of 2023 to the year-ago period, our free cash flow improved by $325 million, and $1.1 billion less revenue. While cash flow in any period can be impacted by the timing of cash collections from transactions and the timing of payments to our agents, vendors, and employees, in relation to each quarter end, the magnitude of the improvement in free cash flow over the past year is directly attributable to the impact of our cost discipline. We had $167 million of cash and cash equivalents on our balance sheet at the end of December, and we have no outstanding balances on our revolving line of credit. We believe we are well-positioned to react to continued market challenges. Now, turning to our financial guidance. Our results from 2023 confirm that our operating expense discipline creates meaningful performance improvement. We will continue this approach, and although the market is expected to increase modestly in 2024, we will be managing our business and our cost levels, assuming a flat level of transactions compared to 2023. For Q1 of 2024, we expect revenue in the range of $975 million to $1.75 billion, and we expect adjusted EBITDA to be in the range of negative $22 million to negative $40 million. For the full year of 2024, we are targeting a non-GAAP OpEx level between $855 million to $875 million, with a midpoint of $865 million, which includes the additional OpEx assumed by the brokerage acquisitions completed at the end of September, and the Florida-based title and escrow acquisition we recently completed in Q1. As Robert mentioned, our commitment to cost discipline has driven significant improvement in our free cash flow compared to the same periods last year. We remain committed to continue our cost discipline to drive favorable results in 2024 and beyond. As a result, we expect to be free cash flow positive for the full year of 2024. Thank you again to our agents and team members for all you do for Compass. I would now like to turn the call back over to the operator to begin Q&A. The floor is now open for your questions.
