Thanks very much, Nancy. Thank you everybody for joining the call. We're going to start with our revenue items on page 3 of the release. We are pleased with our financial results this quarter, as we again produced record net revenues and pretax income for the quarter and also for the year. Commission revenues rose to a record $477 million this quarter. For the full year, commissions were $1.7 billion, up 25% from last year. In 2024, we saw higher trading volumes across the major product categories, as well as 24% higher DARTs per account. Net interest income also reached a quarterly record of $807 million and a yearly record of $3.1 billion, despite multiple rate cuts in nearly all the major currencies. A continued risk-on environment in the quarter led to a significant increase in margin borrowing; and strong net customer deposits led to higher segregated funds balances. These revenues were partially offset by the interest paid to our customers on their cash balances. Other fees and services generated $81 million for the quarter and $280 million for the year, up 47% and 42% respectively. This was primarily driven by the continued risk-on positioning of customers, which has been reflected in rising risk exposure fees over the course of 2024; and to a lesser extent by both higher FDIC sweep fees and by higher payments for order flow from options exchange-mandated programs. Other income includes gains and losses on our investments, our currency diversification strategy and principal transactions. The primary factor here was our previously-reported October sale of a portion of our interest in Tiger Brokers, which led to a one-time realized gain of $34 million. Together with a $10 million mark-to-market unrealized loss for the quarter, the Tiger investment contributed a net gain of $24 million to Other Income. Several of the items in this line are considered non-core and therefore excluded in our adjusted earnings. Without these excluded items, Other income was a $59 million gain for the quarter and $132 for the year. Turning to expenses, Execution, Clearing and Distribution costs were $115 million in the quarter, and $447 million for the year, up versus last year due to higher trade volumes in stocks and options. Overall, commissions rose faster than execution costs, however, thanks to higher rebates earned from exchanges that pay for liquidity enhancing orders. Execution & Clearing costs were 19% of commission revenue in the 4th quarter, for a Gross Transactional Profit margin of 81%. We calculate this by excluding from "Execution, Clearing and Distribution” $21 million of non-transaction-based costs, mainly market data fees, which do not have a direct commission revenue component. Compensation & Benefits expense was $138 million for the quarter, up slightly from the year-ago quarter. Due to the capitalization, rather than expensing, under GAAP of some software development this quarter, compensation expense is about $5 million lower than usual; adjustments of this nature may be made periodically. For the quarter, the ratio of compensation expense to net revenues was 10% and would have been 10.3% had that $5 million of capitalized software been included as comp expense. For the year, this ratio was 11%, down from 12% in 2023. Our headcount at December 31st was 2,998, up 2% for the year. G&A expenses were $59 million, up from the year-ago quarter. For the full year, G&A was $314 million, up 49%, primarily due to a one-time litigation expense in the 3rd quarter. Excluding this, G&A for the year was $236 million, up 12% primarily on higher advertising expense. Our pretax margin was a record 75% for the quarter as reported and 76% as adjusted. Income Taxes of $71 million reflects the sum of the public company’s $34 million and the operating companies’ $37 million. The public company’s effective tax rate was 14%, below its typical range primarily due to a benefit from the annual revaluation of our Deferred Tax Asset. Moving to our balance sheet on page 5 of the Release, our total assets ended the year 17% higher than last year at $150 billion, driven by strong growth in margin lending. New account growth also helped propel our customer credit balances by 14% to a new record level. We believe that our strong financial standing and competitive interest rates provide customers with an attractive place to hold their uninvested cash. We continue to have no long-term debt. Healthy profitability drove our firm equity up 18% to $16.6 billion. In recognition of this growth, we allocated capital to a dividend increase in the 2nd quarter of 2024. We maintain a balance sheet geared towards supporting growth in our existing business and helping us win new business by demonstrating our strength to prospective clients and partners. In our operating data, on pages 6 and 7, we had record customer volume in options, with our contract volumes up 32% over the prior-year, and also up 32% for the full year, well ahead of industry volumes. Futures contract volumes declined 3% for the quarter, but rose 4% for the full year; while stock share volumes rose 65% for the quarter and 22% for the full year. Stock share volume generally increased versus last year as clients gravitated to larger, higher quality names, and traded relatively less in pink sheet and some other very low-priced stocks. Growth in the notional dollar value of shares traded in the quarter was about even with the growth in our share volumes overall. On page 7, you can see that total Customer DARTs were 3.1 million trades per day in the quarter, up 61% from the prior year. Commission per Cleared Commissionable Order of $2.72 was down from last year, primarily due to smaller average order sizes across all product classes, and a shift to proportionally more trading in stocks versus options and futures from last year. Page 8 shows our Net Interest Margin numbers. Total GAAP net interest income was $807 million for the quarter, up $77 million or 11% from the prior year, while our NIM net interest income was $830 million, or $91 million higher. In the NIM computation, we include some income that is classified as Other Fees or Other Income on our income statement, but we believe is more appropriately considered interest. Our Net Interest Income reflects strength in margin loan interest, partially offset by lower segregated cash interest and higher interest expense on customer cash balances. Many central banks made cuts to their benchmark rates this quarter, including the US, Europe, the UK, Switzerland, Canada and Hong Kong. Reflecting multiple rate cuts in most benchmark rates this year, our overall segregated cash interest income declined 2%, despite a 10% increase in average balances, while margin loan interest rose by 26% on a 41% increase in average balances. The average duration of our US Treasury portfolio remains at under 30 days. With the US dollar yield curve continuing to be inverted during the first part of the quarter, though flattening somewhat in the medium term by quarter end, we continue to maximize what we earn by focusing on higher short-term yields, rather than accepting the lower yields and added risk of longer maturities. This strategy allows us to maintain a relatively tight maturity match between our assets and liabilities. Securities lending net interest does not appear as strong as in prior years for three main reasons: First, as benchmark interest rates rose from near zero beginning in 2022, more of what we earned from securities lending became classified as interest on “segregated cash”. We estimate that if the additional interest earned and paid on cash collateral were included under “Securities Borrowed and Loaned”, then securities lending net revenue would have been about $182 million this quarter versus $156 million in last year’s fourth quarter on the same basis. Second, we have seen strong stock market performance, with the S&P up over 20% in each of the past two years, which tends to reflect a smaller proportion of clients looking to put on shorts. Third, there are fewer “hard to borrow” names industry-wide, both because the overall market is rising sharply, and due to weakness in some of the typical drivers of securities lending, including IPOs, market volatility, and merger & acquisition activity. Despite this trend, we were successful in raising the total notional value of what we loaned out. Interest on Customer Credit Balances, the interest we pay to our customers on the cash in their accounts, rose on higher balances from new account growth. As we have noted in the past, the high interest rates we pay on customer cash – currently 3.83% on qualified US dollar balances - is a significant attraction to new customers. Fully rate-sensitive customer balances ended the current quarter at $19.1 billion, versus $17.8 billion in the year ago quarter. Now, for our estimates of the impact of changes in rates. Given market expectations of further rate cuts in the future, we estimate the effect of a 25-basis point decrease in the benchmark Fed Funds rate to be a $64 million reduction in annual net interest income. Note that our starting point for this estimate is December 31st, with the Fed Funds effective rate at 4.33%, and balances as of that date. Any growth in our balance sheet and interest-earning assets would reduce this impact. About 25% of our customer cash balances is not in US dollars, so estimates of a US rate change exclude those currencies. We estimate the effect of decreases in all the relevant non-USD benchmark rates would reduce annual net interest income by about $22 million for each 25-basis point decrease in those benchmarks. At a high level, a full 1% decrease in all benchmark rates would decrease our annual net interest income by about $339 million. This takes into account rate-sensitive customer balances and also firm equity. In conclusion, we posted another financially strong quarter in net revenues and pretax margin, leading to a record year. This reflects our continued ability to grow our customer base and deliver on our core value proposition to customers while simultaneously scaling the business. Our business strategy continues to be effective: Automating as much of the brokerage business as possible, continuously improving and expanding on what we offer while minimizing what we charge. With that, we will now open up the line for questions.
