Standard&Poor's Ratings Services raised its rating on the District of Columbia's GO debt to 'A+' from 'A' based on a continuation of conservative financial management and operations, coupled with significant tax base growth and investment. At the same time, Standard&Poor's assigned its 'A+' rating to D.C.'s new series 2005A GO bonds and 2005B GO refunding bonds, reflecting the following: Management has a strong commitment to maintaining balanced operations and home rule, demonstrated by nine consecutive years of operating surpluses and the buildup of significant general fund reserves. There are statutory financial policies and practices in place that, if not met, would trigger the reoccurrence of the control board and minimize the risk of future financial difficulties.
