Set forth below is an excerpt of the transcript for the first quarter 2011 earnings conference call held by Avis Budget Group, Inc. on May 4, 2011.

Ron Nelson - Avis Budget Group, Inc. - Chairman and CEO

Lastly, let me tackle our proposed acquisition of Dollar Thrifty. While 99.98% of our employees are focusing on delivering results for our shareholders, a small handful of us and a gaggle of lawyers and bankers are also focusing on driving this proposed acquisition to the finish line.

In short, there is not much to report. While we had hoped to have more news related to DTG to share with you by now, sometimes things take longer than one would like. So while we still aren’t ready to talk publicly about our discussions with the FTC, rest assured that we have been working hard on this front and that we remain committed to acquiring Dollar Thrifty. It remains an important growth opportunity for our company, one that moves us squarely into the value arena, results in significant consolidation efficiencies, and, we believe, based on every acquisition completed in the car rental space in the last 10 years, only enhances competition in the industry.

We continue to work closely with DTG and their counsel in order to obtain antitrust clearance for our proposed transaction, and we continue to have a good, constructive dialog with the FTC.

In short, while the acquisition of Dollar Thrifty is an important objective for us, we have also been taking significant steps to manage our organic growth and profitability – and the strength of our first-quarter results highlights the potential that we are unlocking. Beyond that, I really don’t think there is anything further to say on the topic.
