Thank you, Nancy. Thanks, everyone, for joining the call today. We'll start with our revenue items on Page 3 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 $435 million. This quarter, both options and futures volumes reached new quarterly highs as we sell active customers across global regions participated in the markets. Net interest income also reached a quarterly record of $802 million despite rate cuts in several countries including the full impact of second quarter cuts in Europe, Canada and Switzerland and partial quarter impact of third quarter cuts in those countries as well as in the U.S., U.K. and Hong Kong. The continued risk on environment in the quarter led to a significant increase in margin borrowing and strong account growth led to increases in our segregated cash portfolio. These increases were partially offset by the interest paid to our customers on their cash balances. Interactive Brokers pays clients holding U.S. dollars, the benchmark Fed funds rate less 50 basis points on their qualified funds which makes us attractive compared to other brokers and banks and competitive with money market funds. And as a truly global broker, we pay similarly competitive rates on qualified balances in 20 other currencies. Other fees and services generated $72 million, up 38% from the prior year driven by the continued risk on positioning of customers, which is reflected in an increase in the risk exposure fees with contributions also from payments for order flow from options exchange mandated programs and FDIC sweep fees as well. Other income includes gains and losses on our investments, our currency diversification strategy and principal transactions. Note that several of these are noncore items and therefore, are excluded in our adjusted earnings. Without these excluded items, other income was an $18 million gain for the quarter. Turning to expenses. Execution, clearing and distribution costs were $116 million in the quarter, up 18% over the year ago quarter, predominantly from higher regulatory fees that were introduced by the SEC earlier this year. The SEC fee is a pass-through to customers, so it does not impact our profitability. As a percent of commission revenues, execution and clearing costs, were 21% in the third quarter for a gross transactional profit margin of 79%. 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 and benefits expense was $145 million for the quarter for a ratio of compensation expense to adjusted net revenues of 11%, similar to last year's quarter. We remain focused on defense discipline while targeting specific functions to grow the business. Inside our year-over-year staff increase of only 1%, we had good success in hiring talented software developers. And partially offsetting that, we reduced compliance staff as we went into full operational mode with our in-house developed compliance system. Our headcount at September 30th was 2,969. G&A expenses were $75 million, up from the year ago quarter, led by a onetime expense to consolidate our European operations and expenses related to legal and regulatory matters. Excluding these items, G&A was up $9 million to $51 million, primarily on higher advertising expense. Our pretax margin was 72% for the quarter, both as reported and as adjusted. Income taxes of $80 million reflects the sum of the public company's $45 million and the operating company's $35 million. The public company's effective tax rate was 18.4%, within its usual range. Moving to our balance sheet on Page 5 of the release. Our total assets ended the quarter 23% higher than the prior year quarter at $148 billion, driven by strong growth in margin lending. New account growth also helped propel our customer credit balances by 19% to a new record level. And we believe that our strong financial standing and competitive interest rates provide customers with an attractive place to hold their idle cash. We continue to have no long-term debt and healthy profitability drove our 21% increase in firm equity over the prior year quarter. And in recognition of this growth, we allocated capital to a dividend increase last quarter. We maintained 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 contract volume in both options and futures. And options and our contract volumes rose 35% over the prior year quarter, well above industry growth. And futures contract volumes rose by 13%. Stock share volumes rose by 22%, also above industry growth. Stock share volume generally increased versus last year as clients in our largest markets, gravitated to larger, higher-quality names and trading relatively less in pink sheet and other very low-priced stocks. Growth in the notional dollar value of shares traded well outpaced the growth in share volumes. On Page 7, you can see that total customer DARTs were 2.7 million trades per day, up 42% from the prior year. Commission per cleared commissionable order of $2.83 was down from last year, primarily due to smaller average order sizes across product classes, which is more than compensated by stronger volumes. Turning to net interest income on Page 8. Total GAAP net interest income was $802 million for the quarter, up 9% on the prior year, while our NIM net interest income was $826 million or $24 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 and segregated cash interest, partially offset by higher interest expense on customer cash balances. Several central banks made cuts to their benchmark rates this quarter, the U.S., U.K. and Hong Kong cut for the first time since early 2020, while Europe, Switzerland and Canada cut their rates both this quarter and last. Reflecting relatively flat benchmark rates year-on-year, our segregated cash interest income rose 5% on a 6% increase in average balances, while margin loan interest rose by 26% on a 28% increase in average balances. The average duration of our U.S. treasury portfolio remains at less than 30 days. With the U.S. dollar yield curve continuing to be inverted except in the very near term. We have been maximizing what we earn by focusing on higher short-term yields rather than accept the significantly lower yields of longer maturities. This strategy allows us to maintain a relatively tight maturity match between our assets and liabilities and positions us to be nimble if the yield curve does revert. Securities lending net interest has not been as strong as in prior quarters for three main reasons. First, an extremely strong stock market with a backdrop of a falling rate environment, coincides with a smaller proportion of clients looking to put on shorts. Second, there are fewer hard-to-borrow names industry-wide, not only because the overall market is rising sharply, but also due to the weakness in some of the drivers relevant to securities lending, including IPOs, low market volatility and merger and acquisition activity. So even though the notional value of what we are lending was higher than last year's quarter, overall industry average lending rates are lower. Finally, as noted on previous calls, higher average interest rates versus prior year periods means more of what we earn from securities lending is classified as interest on segregated cash. To more accurately reflect all the income, we earn from our securities lending business, we estimate that if the additional interest earned and paid on cash collateral were included under securities borrowed and loan, then total net revenue related to our securities lending business would have been about $156 million versus $181 million in the year ago quarter. This additional revenue would be reclassified from the line items, interest earned on segregated cash and interest paid on customer credit balances. So overall, it would have no effect on our net interest margin. Interest on customer credit balances, the interest we pay to our customers on the cash and 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 4.33% on qualified U.S. dollar balances is a significant attraction to new customers. Fully rate-sensitive customer balances were $19.5 billion this quarter versus $17.1 billion in the year ago quarter. Together with firm equity, most of which consists of interest-earning assets, total fully rate-sensitive balances were $33.6 billion. 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 September 30 with the Fed funds effective rate at 4.83% and balances as of that date. Any growth in our balance sheet and interest-earning assets would reduce this impact. About 24% of our customer cash balances is not in U.S. dollars. So estimates of the U.S. rate change exclude those currencies. We estimate the effect of decreases in all of the relevant non-U.S. benchmark rates, which reduced annual net interest income by $18 million for each 25 basis point decrease in those benchmarks. At a high level, a full 1% decrease in all benchmark rates will decrease our annual net interest income by $328 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.
