Standard & Poor's Ratings Services assigned its 'BBB-' rating, and stable outlook, to Newport Municipal Utility District (MUD), Texas' series 2005 waterworks and sewer system combination unlimited-tax and revenue bonds. The rating reflects the district's: High debt burden; Future capital needs; and Elevated property tax rate, which is needed to service debt. These weaknesses are offset, in part, by the district's: Healthy property tax base growth, coupled with access to the Houston MSA; and Adequate financial position.
