Thank you. Good evening, ladies and gentlemen, and welcome to Pegasystems Q4 2018 earnings call. Before we begin, I'd like to read our Safe Harbor statement. Certain statements contained in this presentation may be construed as forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. The words expects, anticipates, intends, plans, believes could, should, estimates, may, targets, strategies, intends to, projects, forecasts, guidance, likely and usually or variations of such words and other similar expressions identify forward-looking statements, which speak only as of the date of the statement was made and are based on current expectations and assumptions. Because such statements deal with future events, they are subject to various risks and uncertainties. Actual results for fiscal year 2019 and beyond could differ materially from the company's current expectations. Factors that could cause the company's results to differ materially from those expressed in forward-looking statements are contained in the company's press release announcing its Q4 2018 earnings and in the company's filings with the Securities and Exchange Commission including its annual report on Form 10-K for the year ended December 31, 2018 and other recent filings with the SEC. Investors are cautioned not to place undue reliance on such forward-looking statements and there are no assurances that the matters contained in such statements will be achieved. Although, subsequent events may cause our view to change, except as required by applicable law, we do not undertake and specifically disclaim any obligation to publicly update or revise these forward-looking statements whether as a result of new information, future events or otherwise. And with that, I'll turn the call over to Alan Trefler, Founder and CEO of Pegasystems.
