The White House has said President George Bush will sign the bill into law. The most important change from present law is a drastic alteration in the way postal rates are set: the present system of regulation by the Postal Rate Commission is now replaced with a system that permits the Postal Service to establish its own rates, subject (for most mail, including periodicals) to a Consumer Price Index-based price cap that effectively limits the average increase for each class to the CPI. It is expected that, once the new system is in place in mid-2008, the Postal Service will raise rates annually by the maximum permitted. http://www.fipp.com/Default.aspx?PageIndex=2002&ItemId=13540; January 23, 2007
