S&P Global Ratings affirmed its 'AA+' long-term and underlying rating on King County, Wash.'s outstanding parity-lien sewer revenue bonds and its 'AA' rating on the county's junior-lien sewer revenue bonds. The outlook is stable. In addition to the above bonds, the county has parity-lien limited-tax general obligation bonds (LTGO) refunding bonds and multi-modal LTGO bonds payable from sewer net revenues as well.
