Net income fell to $55.5 million, or $1.91 per share, for the third quarter, from $66.6 million, or $2.13 per share, a year earlier. Rental revenue rose about 1.5 percent to $442.3 million. Total revenue rose 2 percent to $460.6 million. Analysts on average expected the company to earn $1.69 per share on revenue of $454.1 million, according to Thomson Reuters I/B/E/S.
