Standard&Poor's Ratings Services assigned its 'AA' long-term rating to Sioux City, Iowa's series 2014A general obligation (GO) bonds and series 2014B taxable GO bonds, based on its local GO criteria released Sept. 12, 2013. At the same time, we affirmed our 'AA' ratings on the city's outstanding GO bonds. The outlook on all the ratings is stable. A pledge of the city's full faith and credit and an agreement to levy ad valorem property taxes without limit as to rate or amount secures the 2014A and B bonds. The city intends to use the 2014A proceeds for various infrastructure projects and equipment purchases. Series 2014B proceeds will be used for various public improvements within designated urban renewal areas
