During a Special Open Meeting convened on Monday, August 30, 2010, the five ACC Commissioners passed, by a vote of 5 - 0, an amended order that reduced Global Utilities' proposed increase in rates.  The Commission's final Decision adopts RUCO's recommended 9.00 percent cost of common equity and ACC Staff and RUCO's recommendation to treat Global Utilities' Infrastructure Coordination and Financing Agreements ("ICFA") as contributions-in-aid-of-construction.  The Final Decision also opens a generic docket for the purpose of establishing a working group, which will be open to concerned stakeholders, that will study how ICFA's should be treated in future rate case proceedings.
