SAN FRANCISCO (Standard&Poor's) Jan. 24, 2013--Standard&Poor's Ratings Services revised its outlook to negative from stable and affirmed its 'AA' long-term rating and underlying rating (SPUR) on Los Angeles, Calif.'s solid waste resources (SWR) and sanitation equipment bonds. In addition, we assigned our 'AA' long-term rating to the city's $71.7 million series 2013A SWR revenue bonds and $80.7 million series 2013B solid waste resources refunding revenue bonds. "The outlook revision reflects our view of the city's projected increase in operating costs and mostly debt-financed large capital improvement program," said Standard&Poor's credit analyst Paul Dyson. The rating reflects our view of the city's: Historical willingness and ability to adjust the SWR fee to cover debt service
