Part II- Rules Applicable to Code or block holders that have filed Only One or Two NRUF Reports

Code or block holders, which have acquired and retained public numbering resources and have filed one or two NRUF Reports with NANPA must abide by the following guidelines. A separate calculation shall be made for each rate center within each area code within which the carrier holds an inventory of numbering resources:

· Calculate the change in the historical demand for telephone numbers, which represents the code or block holder's actual growth. Code or block holders shall use the most recently filed NRUF Report (NRUF at time 2). The change in the historical demand for telephone numbers comprises of those telephone numbers categorized as Assigned or Intermediate in the NRUF Reports. The formula for calculating the change in the historical demand for telephone numbers shall be (Assigned numbers + Intermediate numbers as of NRUF at time 2).

· Determine the appropriate growth rate whereby the maximum growth rate is 15% to use to calculate the projected growth in telephone numbers for the next six months.

· Compute the projected growth in telephone numbers. The formula shall be the product of the change in the historical demand for telephone numbers and the appropriate growth rate.

· Find out the excess inventory of telephone numbers. The formula shall be the difference of the Available numbers reported in NRUF at time 2 and the projected growth in telephone numbers.

· Figure out the short-term inventory level. The formula shall be the difference of the total numbering resources and the excess inventory of telephone numbers.
