On May 21, 2009, Rio Rico Utilities, Inc. (“Rio Rico” or “Company”) filed an application for the Company's utility operations in Santa Cruz County ("Application") with the Arizona Corporation Commission ("ACC" or "Commission").

Rio Rico is a Class A utility that provides water and wastewater service to approximately 6,000 customers (4,000 water only customers and 2,000 wastewater only customers) the majority of which are residential ratepayers. The Company has chosen a test year ended December 31, 2008 (“Test Year”). Rio Rico’s present rates were established in Decision No. 67279, dated October 5, 2004. The Company is a subsidiary of the Algonquin Power Income Fund, a Canadian mutual fund that is based in Toronto, which also owns other public service companies in Arizona including Litchfield Park Service Company, Bella Vista Water Company, Gold Canyon Sewer Company and Black Mountain Sewer Corporation.

According to Rio Rico’s Application, the Company's Water Division had adjusted gross revenues of $1,847,256 and an operating loss of $214,606 during the Test Year resulting in negative rate of return of 2.54 percent on an adjusted fair value rate base of $8,455,517. During the same period, the Company's Wastewater Division had adjusted gross revenues of $1,829,976 and an operating income of 490,676 resulting in a positive rate of return of 13.96 percent on an adjusted fair value rate base of $3,516,078.
