Tradeweb Markets Inc.

Good morning, and welcome to the TradeWeb's fourth quarter 2021 earnings conference call. As a reminder, today's conference call is being recorded and will be available for playback. To begin, I'll turn the call over to Head of Treasury, FP&A, and Investor Relations, Ashley Seurat. Please go ahead.

Thank you and good morning.

Joining me today for the call are our CEO, Lee Oleski, who will review the highlights for the quarter and provide a business update. Our president, Billy Hult, who will dive a little deeper into some growth initiatives, and our CFO, Sarah Ferber, who will review our financial results. We intend to use the website as a means of disclosing material, non-public information, and complying with disclosure obligations under SEC Regulation FD. I'd like to remind you that certain statements in this presentation and during the Q&A may relate to future events and expectations, and as such constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Statements related to, among other things, our guidance are forward-looking statements. After results may differ materially from these forward-looking statements. Information concerning factors that could cause actual results to differ from forward-looking statements is contained in our earnings release and periodic reports filed with the SEC. In addition, in today's call, we will reference certain non-GAAP measures. Information regarding these non-GAAP measures, including reconciliations to GAAP measures, are in our posted earnings release and presentation. To recap, this morning we reported GAAP earnings with a glued-off share of 23 cents. Excluding certain non-cash stock-based compensation expense, acquisition-related transaction costs, acquisition refinance-related DNA, and certain FX items, and assuming an effective tax rate of 22%, we reported adjusted net income per diluted share of $0.42. Please see the earnings release and the Form 10-K to be filed with the SEC for additional information regarding the presentation of our historical results. Now, let me turn the call over to Lee.
