Standard & Poor's Ratings Services said it raised its long-term rating to AA-minus from A-plus on Novato Sanitary District, Calif.'s wastewater revenue certificates of participation.
The outlook is stable.
"The raised rating reflects our view of the district's strengthening financial profile during the past three fiscal years, including enhanced unrestricted reserves, and a developing track record of managing a more substantial debt load," said Standard & Poor's credit analyst Tim Tung.
