NEW YORK (Standard&Poor's) Jan. 20, 2012--Standard&Poor's Ratings Services revised its outlook to negative from stable on Glendale Municipal Property Corp., Ariz.'s senior-lien excise tax revenue refunding bonds, Glendale, Ariz.'s second-lien series 14 and 16 certificates of participation (COPs), and Western Loop 101 Public Facility Corp., Ariz.'s third-lien excise-tax revenue bonds.
