And thank you for joining us for our first quarter 2025 earnings call. Joining us today are Thomas Peterffy, our Founder and Chairman, Milan Galik, our President and CEO, and Paul Brody, our CFO. I will be presenting Milan's comments on the business, and all three will be available at our Q&A. As a reminder, today's call may include forward-looking statements which represent the company's belief regarding future events, which by their nature are not certain and are outside of the company's control. Our actual results and financial condition may differ, possibly materially, from what is indicated in these forward-looking statements. We ask that you refer to the disclaimers in our press release. You should also review a description of risk factors contained in our financial reports filed with the SEC. We saw in the first quarter the value of a global automated platform that can leverage its low costs and offer a broad range of products and markets. After a solid January, buoyed by post-US election enthusiasm, market indexes around the world reached peaks in February in the US, and early March everywhere else after two years of nearly unbroken market increases. After that, cracks in the market began to show. News of DeepSeq and its less capital-intensive AI caused the market to give back half its gains in February. Talk about tariffs further accelerated the decline in March. The S&P 500 ended the quarter down 5% but it was off 9% from February peak. Six of the magnificent seven, the seven stocks that have dominated investor attention, fell significantly more than the market this quarter. However, Interactive Brokers Group does not need up markets to generate revenue. Our customers were active and remained faithful to their favorite names. Of our 25 most active names, 22 saw net buying activity. We also saw global interest from investors, both institutional and individual, in opening accounts. Internationally, it remains the case that investors want broad portfolios with some invested in securities in their home markets, and a more significant portion overseas. Product-wise, the popularity of options continued. With our contract volumes up 25% to a quarterly record, Futures volumes are up 16%, also to a record. And stock share volumes are up 47%. Our volume growth rates were ahead of industry volumes. What all of the above has meant for our business starts with strong account growth as we add more investors to our platform. In the first quarter, we added 279,000 new accounts, a record that well surpassed even the meme stock days of the first quarter 2021. Total account growth was 32% with even faster growth internationally. New accounts meant more cash in those accounts, which helped raise our client credit balances 19% to a record $125.2 billion. Our client equity rose 23% versus 2024 to $573.5 billion. And was up 1% in the quarter despite the drop in the market. This translated into strong financial results. Quarterly commission revenue was a record reaching half a billion dollars for the first time as were total net revenues. We do not only focus on the top line, however. Our expenses remained well controlled and our adjusted pretax profit margin was an industry-leading 74%. The eighth time our adjusted pre-tax margin reached 70% or more. Recognition of this and as a sign of confidence in the strength of our business model, its growth potential and of our capital base, we revisited our allocation of capital and decided to increase the amount of dividend we pay to 32 cents a quarter. We will also split the stock four for one to achieve greater liquidity in our float. And to make it more affordable for shareholders to buy round lots in the company. With respect to M&A, we have not stopped looking at potential acquisitions. Realistically, there is a dearth of opportunities at a price that makes sense for us. In most cases, because target companies charge more and pay less interest than we do, when we run their accounts using our pricing, the income we estimate and put a multiple on is lower than what they wish. We will keep looking, but in the meantime, for now, returning capital to shareholders via the dividend makes sense. In terms of how the business looked on the client front, our accounts and client equity once again grew fastest in Asia, with Europe a close second. Again, the trend of growing numbers of investors worldwide wanting to international particularly US markets, has not waned. Individuals saw the fast account growth among our five client segments with introducing brokers and proprietary traders not far behind. On the client equity side, individuals grew fastest, with introducing brokers and proprietary trading clients just behind them. Commission-wise, individuals saw the fastest growth. Followed closely by proprietary traders. All net interest growth was led by individuals, followed by financial advisers. Regarding introducing brokers, our pipeline of potential clients remains healthy. We are onboarding iBrokers to the platform, and adding prospective ones to it. At a steady pace. Onboarding iBrokers can take time, since we offer a variety of ways for them to come onto our platform. The more complex the iBroker, the more time needed. We customize our offering for larger iBrokers needs, with many needing special programming on our part to make sure their client's investment tax, and compliance needs are met. We are up to the task. In terms of new product introductions, we had a busy quarter. We began offering our forecast x contracts in Canada, as well as across the EEA for professional clients. And we will soon roll them out to the general EEA population. We added to our growing portfolio of country-specific savings and investment accounts launching Canadian first home savings accounts this quarter. We added four new cryptocurrencies, Solana, Cardano, Ripple, and Dogecoin, and last week introduced three more. Chainlink, Avalanche, and Sui. Bringing our total offering to eleven cryptocurrencies. We launched trading of Nifty fifty index futures in Singapore, and of equities in Slovenia. We recently made Forecast Trader available so clients using our IBKR desktop or trader workstation platforms can simultaneously use ForecastTrader side by side. We continue to see increasing activity in our overnight trading hours. We offer over ten thousand US stocks and ETFs, as well as US equity index futures and options, And on the fixed income side, global corporate bonds, plus US Treasury and European and UK government bonds. We added a focused overnight plus day order type so clients can submit an order in the overnight hours that will remain open until the end of the next regular trading session. Overall, our overnight volumes grew 250% from first quarter 2024 to first quarter 2025. We spent significant time this quarter on our client service and onboarding projects, our compliance and regulatory projects, and on further automating our internal operations to make them run more efficiently. We are as busy as we have ever been. With multiple projects touching all client types and geographic regions. We are excited to introduce them to you in the quarters ahead. Automating substantial parts of the brokerage business for client success is the heart of what we do. While market direction may appear significant in the short run, the long-term trend towards more global investing across multiple customer types and jurisdictions continues. This trend and our ability to serve it with a much lower cost structure and a much broader product and tool set is what sets us apart and we will continue to do so in the years ahead. With that, I will turn the call over to Paul Brody. Paul?
