Thank you, Karen, and good afternoon, everyone. Thank you for joining us for the Tessera Technologies fourth quarter 2007 results conference call. By now, you should have received a copy of the press release. If you have not, please contact Lippert/Heilshorn & Associates at 415-433-3777 and we will forward a copy to you. This call is being broadcast live over the Internet. A webcast replay will be available at tessera.com for 90 days after the call. In addition, a telephone replay of this call will be made available for 48 hours beginning approximately two hours after the conclusion of this call. To listen to the replay in the US, please dial 800-642-1687, and internationally, dial 706-645-9291. The access code is 30192448 I will now read a short safe harbor statement. During the course of this conference call, management may make projections or other forward-looking statements, which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties that could cause actual results to differ significantly from those projected. You are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this release. A detailed discussion of the material factors that may cause results to differ from the statements made can be found, for example, in the Risk Factors sections of Tessera's filings with the Securities and Exchange Commission, including its annual report on Form 10-K for the year ended December 31, 2006 and its quarterly report on Form 10-Q for the quarter ended September 30, 2007. On the call today from management are Bruce McWilliams, Tessera's Chairman, President and Chief Executive Officer, and Charlie Webster, Chief Financial Officer. During this call today, management will discuss certain non-GAAP financial measures for comparison purposes only, and they will be using non-GAAP numbers in their prepared remarks. The non-GAAP amounts of cost of revenues; research and development; selling, general and administrative expenses; net income; and earnings per share do not include three items: stock-based compensation, deal amortization charges and non-cash tax expense. Tessera includes only actual cash taxes in its non-GAAP results because the company does not currently pay federal or state income taxes and not expect to do so until sometime in 2008. Management believes the non-GAAP amounts provide a more meaningful comparison measure of quarter-over-quarter and year-over-year financial performance. Please refer to the company's fourth quarter 2007 earnings press release and to the company's website for reconciliation of non-GAAP measures to GAAP. After management's opening remarks, we will open the call to your questions. So that management is able to respond to as many of you as possible, please restrict yourself to an opening and a follow-on question. Please re-enter the queue if you have additional questions. And with that, I'll turn the call over to Bruce.
