Thank you, Nancy. Good afternoon, everyone. I will review our third quarter results, and then we'll open it up for questions. Starting with our revenue items on Page three of the release, we're pleased with our financial results this quarter as we again produced record net revenues and pretax income. Commissions rose to a record $537 million, 23% above last year's third quarter. We continue to see higher trading volumes from our growing base of active customers outpacing industry volumes across major product classes. Our options volume rose 27% and set a new quarterly volume record, and equity volumes were up 67% from last year. Net interest income also reached a quarterly record of $967 million, despite lower benchmark rates in most major currencies. Higher segregated cash and margin loan balances and significantly stronger securities lending contributed to these results. Net interest income also received a benefit from lower benchmark rates on the interest we pay our customer cash balance. Other fees and services generated $66 million, down 8% from the prior year, driven by more cautious risk-taking by clients, leading to lower risk exposure fees, partially offset by positive contributions from higher FDIC sweep and market data fees. Other income includes gains and losses on our investments, our currency diversification strategy, and principal transactions. Note that many of these noncore items are excluded in our adjusted earnings. Other income was $85 million as reported and $50 million as adjusted, primarily driven by a gain on a long-held investment. Turning to expenses, execution and clearing, execution, clearing, and distribution costs were $92 million in the quarter, down 21% from the year-ago quarter primarily due to two factors. First, we had a full quarter effect of the SEC reducing its fee rate to zero after it was cut midway through the second quarter. SEC fees were $20 million in the third quarter last year and $24 million in 2025. And second, we achieved higher rebates and lower costs at exchanges resulting from our smart order routing optimization. These costs and rebates are largely passed through to customers, so these reductions don't have much impact on our profitability, but they are components of our clients' profitability and one of the reasons they execute through us. As a percent of commission revenues, execution and clearing costs were 13% in the third quarter for a gross transactional profit margin of 87%. We calculate this by excluding from execution, clearing, and $21 million of non-transaction-based costs, predominantly market data fees, which do not have a direct commission revenue component. Compensation and benefits expense was $156 million for the quarter, for a ratio of compensation expense to adjusted net revenues of 10%, down from last year's quarter. As always, we remain focused on expense discipline as reflected in our moderate staff increase of 5% over the prior year. Our headcount at September 30 was 3,131. G&A expenses were $62 million, down from the year-ago quarter, which included a legal settlement that added $78 million and a one-time charge of $12 million to consolidate our European operations. Without those items, last year's G&A expense would have been $63 million, about level with the current quarter. G&A was also driven by an increase of $10 million in advertising expenses. Our pretax margin was 79% for the quarter, both as reported and as adjusted. Income taxes of $126 million reflect the sum of the public company's $64 million and the operating company's $62 million. The public company's effective tax rate was 19.4% within a usual range. Moving to our balance sheet on Page five of the release, our total assets ended the quarter 35% higher than the prior year quarter end at $200 billion, with growth driven by higher margin lending and segregated cash balances. New account growth also helped drive our record customer credit balances. The numbers seem to be supporting our long-held view that our strong financial standing and competitive interest rates provide customers with an attractive place to hold their idle cash. We have no long-term debt. Profit growth drove our firm equity up 22% over the prior year quarter to $19.5 billion. We maintain a balance sheet geared towards supporting growth in our existing businesses and helping us win new business by demonstrating our strength to prospective clients and partners, while also considering overall capital allocation. In our operating data, on pages six and seven, our customer trading volumes surpassed industry growth over the prior year quarter in our three major product classes. Options contract and share volumes rose 27% and 67%, respectively. Futures volumes declined 7% in an environment of weaker industry activity. Stock volumes were driven both by increased activity levels overall and by relatively higher trading in low-priced stocks. On page seven, you can see that total customer DARTs were 3.6 million trades per day, up 34% from the prior year, strong in options and stocks. Commission per cleared commissionable order of $2.70 was down from last year, primarily due to the elimination of the SEC fee and the performance of our smart order router leading to the capture of higher exchange rebates and minimizing exchange costs, which as pass-throughs, serve to lower both our commission revenues and our execution and clearing costs. Page eight shows our net interest margin numbers. Total GAAP net interest income was up 21% from the year-ago quarter to $967 million. Adjusted for the net interest margin presentation, net interest income was $999 million. We include for NIM purposes certain income that is more appropriately considered interest, but that for GAAP purposes is classified as other fees and service or as other income. Our net interest income reflects strength in segregated cash interest, margin loan interest, and securities lending, partially offset by a modest increase in interest expense that was moderated by lower benchmark interest rates on customer cash balances. Most central banks, including the UK, Canada, Australia, Hong Kong, and the US, reduced rates this quarter, while others, including Europe, Switzerland, and Japan, held steady. Year on year, the average US Fed funds rate fell 96 basis points or by 18%. Despite this decline, our segregated cash interest income was up 3% on higher balances, while margin loan interest was up 4%, bolstered by higher lending balances. The average duration on our investment portfolio remained at less than 30 days. The U.S. Dollar yield curve remains inverted from the short to medium term, so we continue to maximize what we earn by focusing on short-term yields rather than accept the lower yields and higher duration risk of longer maturities. Particularly in an unpredictable economic environment, this strategy also allows us to maintain a relatively tight maturity match between our assets and liabilities. Securities lending net interest was stronger this quarter. We saw a higher level of short activity and a significant rise in the total notional dollar value of securities we lend. Contributors to this growth include several factors. As our account base has grown, our inventory of attractive stocks to lend has grown with it, including international securities around the world. We pay interest on short cash balances, which makes us attractive to investors who feel our short selling. Our fully paid lending program generally shares proceeds with clients on a fifty-fifty basis, which appeals to investors looking to maximize the return on their portfolios. And activity has picked up in some of the typical drivers of securities lending, including IPOs, and merger and acquisition activity. As most benchmark interest rates are now sufficiently above zero, a portion of what we earn from securities lending is 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 total net revenue related to securities lending would have been $314 million this quarter, double the $156 million we earned in the prior year quarter. Interest on customer credit balances, the interest we pay to our customers on the cash in their accounts, rose slightly on the combination of 33% higher client cash balances from new account growth, and from lower benchmark rates. As we have noted in the past, the higher interest rates we pay on customer cash, currently 3.59% on qualified US dollar balances, is a significant attraction to new customers. Fully rate-sensitive customer balances ended the current quarter at $25 billion versus $19.5 billion in the year-ago quarter. Now for our estimates of the impact of changes in rates, given the market expectations for the rate cuts in 2025, we estimate the effect of a 25 basis point decrease in the benchmark Fed funds rate to be a $77 million reduction in annual net interest income. Our starting point for this estimate is September 30, with the Fed funds effective rate at 4.09% and balances as of that date. Any growth in our balance sheet and interest-earning assets would reduce this impact. About 29% of our customer interest-sensitive 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-US benchmark rates would reduce annual net interest income by $35 million or a 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 $417 million. This takes into account rate-sensitive customer balances and firm equity. In conclusion, we posted another financially strong quarter in net revenues and pretax margin, reflecting our continued ability to grow our customer base and deliver on our core value proposition to customers while scaling the business. Our business strategy continues to be effective, automating as much of the brokerage business as possible, continuously improving and expanding what we offer while minimizing what we charge. With that, we will open up the line for questions.
