TULSA, Oklahoma ( TheStreet) -- Dollar Thrifty ( DTG) will stick with its stand-alone plan. In a statement, Dollar Thrifty said a buyout offer from Hertz ( HTZ) wasn't acceptable and so "having received no acceptable offer after conducting an unprecedentedly open process with clearly articulated requirements, it is time for us to move forward on a stand-alone basis." Instead, the car rental company said it would begin a buyback program of $400 million of stock. Dollar Thrifty also reiterated it expects third-quarter rental revenue to increase by about 2% from a year earlier. -- Written by Joseph Woelfel >To contact the writer of this article, click here: Joseph Woelfel >To submit a news tip, send an email to: email@example.com.
