4901:1-7-20 Cost study requirements.

(A) When a local exchange carrier (LEC) submits a cost study to the commission staff, it must simultaneously submit a complete set of supporting work papers and source documents.

(B) The work papers must clearly and logically present all data used in developing the estimate and provide a narrative explanation of all formulas or algorithms applied to these data. These work papers must allow others to replicate the methodology and calculate equivalent or alternative results using equivalent or alternative assumptions.

(C) The work papers must clearly set forth all significant assumptions and identify all source documents used in preparing the cost estimate, including the technology being used in providing the element.

(D) The work papers must be organized so that a person unfamiliar with the study will be able to work from the initial investment, expense, and demand data to the final cost estimate. Every number used in developing the study must be clearly identified in the work papers as to what it represents. Further, the source should be clearly identifiable and readily available, if not included with the work papers.

(E) Any input expressed as a "dollars per minute," "dollars per foot," "dollars per loop," "dollars per port," and the like must be traceable back to the original source documents containing the number of dollars, minutes, feet, loops, ports, and the like from which these figures were calculated.

(F) All data and work papers must be provided in electronic format.
