Fully Distributed Cost Study

(a)The utility shall submit its fully distributed cost study in both electronic and paper format simultaneously with filing its CAAM for all Colorado divisions and activities.#

(b)The utility shall prepare a FDC study that identifies all the non-regulated activities provided by each division in Colorado. The FDC study shall show the revenues, expenses assets, liabilities and rate base items assigned and allocated to each non-regulated activity. If the utility has more than one division (e.g., gas, electric, thermal or non-utility) in Colorado, the FDC study shall include a summary of all assigned and allocated costs by division.#

(c)In preparation of its FDC study, the utility shall complete an analysis of each non- regulated activity to identify the costs that are associated with and/or should be charged to each non-regulated activity to ensure each non-regulated activity is assigned and allocated the appropriate amount of revenues, expenses, assets, liabilities and rate base items.#

(d)If the CAAM is filed in connection with a rate case, the FDC study shall be based on the same test year used in the utility's rate case filing. The utility's FDC study shall include revenues, expenses, assets, liabilities and rate base items in order for the Commission to determine if all appropriate revenues, expenses, assets, liabilities and rate base items have been appropriately assigned and allocated, and to determine the utility's compliance with the principles established in rule 4502. For each assignment and allocation the utility shall:#

(I)identify the revenues, expenses, assets, liabilities and rate base items by account number, sub-account number and account description; and#

(II)for each account in (I) above, identify the assignment and allocation method used to assign and allocate costs in sufficient detail to verify the assignment and allocation method used to assign and allocate costs to Colorado divisions and activities is accurate and consistent with the utility's CAAM methodology and reference the CAAM section that describes the allocation; and#

(III)provide the test year dollar itemized amounts of revenues, expenses, assets, liabilities, and rate base assigned and allocated to each Colorado division and non-regulated activity; the itemized amounts assigned and allocated to the Colorado utility for regulated activities; the itemized amounts assigned and allocated to the Colorado utility for Colorado non- regulated activities; and the itemized amounts assigned and allocated to other jurisdictions.#

(e)Each utility shall maintain all records and supporting documentation concerning its FDC study for so long as such study is in effect or are subject to a complaint or a proceeding before the Commission.#
