One Liberty CEO Patrick Callan said, "business has stabilized, and we look forward to being proactive in 2010 in the acquisition area, as evidenced by our purchase in February of this year of a 194,000 square foot shopping center located in suburban Philadelphia for $23.5 million." One Liberty Properties also announced fourth-quarter revenues slightly ahead of street consensus of $9.5 million, at $9.8 million in revenues for the final quarter of 2009.
