Both the Presidential Commission on the U.S. Postal Service and GAO's past work have reported that universal postal service is at risk and that comprehensive postal reform legislation is needed to minimize the risk of a significant taxpayer bailout or dramatic postal rate increases. In April 2001, GAO added the Postal Service's (the Service) transformation efforts and long-term outlook to its High-Risk List. GAO has testified that comprehensive postal reform legislation is needed to clarify the Service's mission and role; enhance governance, transparency, and accountability; improve regulation of postal rates and oversight; help to ensure the rationalization of the Service's infrastructure and workforce; and make certain human capital reforms. The Service has made significant progress on some of its key challenges but postal reform legislation continues to be needed in order to facilitate a broader transformation effort. To help Congress and other stakeholders understand Service progress and the need for postal reform, GAO will focus on (1) Service progress since GAO put Service transformation efforts and long-term outlook on GAO's High-Risk List, (2) why comprehensive postal reform legislation is needed, and (3) key areas for comprehensive postal reform. This testimony is based on an update of GAO's statement to Congress last year.
