Bill, would you like to begin?
Thank you, Jeanne, and good afternoon, everyone. Second quarter was another very strong quarter for Liberty. We leased over 5.4 million square feet, our best quarter in a year-and-a-half, and our third-best quarter in the company's history.
Occupancy increased by 20 basis points overall to 90.7%. Our renewal rate was over 60% and our retention rate was over 92%, the highest ever. We (Inaudible) $209 million of real estate, which was 2.7 million square feet of predominantly suburban office and high-finish flex, including the large repositioning sale we've discussed over the last several calls.
We acquired over 600,000 square feet of predominantly industrial value-add real estate in Minnesota and Phoenix, and our development pipeline continue to be strong with the addition of three new projects bringing the pipeline to $310 million a total of 3.3 million square feet.Finally, a preferred redemption in an unsecured debt transaction further strengthened our already robust balance sheet. George, Mike and Rob will provide further color on all this activity in a moment.

With unemployment stock at 8.2%.

Small and mid-size local prospects are behaving more defensively given this environment, but larger or corporate customers are one might turn (Inaudible) are very active. Thinking about long-term decisions and (Inaudible) cash planning offensively.
