A letter report issued by the Government Accountability Office with an abstract that begins "The General Services Administration's (GSA) 218 high-value leases GAO reviewed represented only about 3 percent of the total number of GSA leases, yet made up about one-third of its leased portfolio in terms of cost and size. GSA has reduced the costs of its high-value leases in line with the administration's goal to reduce real property costs. GSA's efforts include helping agencies improve space utilization. However, for leases nearing expiration, GSA and tenant agencies have faced challenges in funding space renovations and moving costs. This lack of funds has contributed to delays and some cases in which GSA continues to occupy space after the lease expires."

A letter report issued by the Government Accountability Office with an abstract that begins "The number of Medicare prostate cancer-related intensity-modulated radiation therapy (IMRT) services performed by self-referring groups increased rapidly, while declining for non-self-referring groups from 2006 to 2010. Over this period, the number of prostate cancer-related IMRT services performed by self-referring groups increased from about 80,000 to 366,000. Consistent with that growth, expenditures associated with these services and the number of self-referring groups also increased. The growth in services performed by self-referring groups was due entirely to limited-specialty groups--groups comprised of urologists and a small number of other specialties--rather than multispecialty groups."
