NEW YORK (Standard&Poor's) March 3, 2010--Standard&Poor's Ratings Services has assigned its 'AAA' rating on the District of Columbia's income tax revenue bonds, series 2010A (tax-exempt) and series 2010B (taxable) Build America Bonds. The bonds are secured by a statutory lien and pledge on the trust estate, consisting primarily of income tax revenues and business franchise taxes (income taxes) generated in the district and received by the collection agent, trustee, or district in any fiscal year.
