To meet the space requirements of our clients, GSA has entered into more than 9,285 private sector leases in 8,094 locations nationwide. At 191 million rentable square feet, leased space comprises more than half of our total portfolio square footage. The vacant space within our leased inventory has been 1.5 percent or below for the last five years, well below the national industry average of 16.7 percent. We strive to keep leasing costs at or below market levels and have developed comprehensive strategies to do so, including the standard use of industry benchmarks and market surveys to comparison shop for the best value for our customers. PBS is seeking authorization for the balance of our FY2011 programs, and intends to submit prospectus-level leases for the FY2012 program this summer.
