2. May 21, 2010B&C WG2 Mission Statement / Area of Responsibility The Billing and Collection Agent Oversight Working Group (B&C WG) was chartered by and reports to the North American Numbering Council (NANC) and is responsible for overseeing the performance of the functional requirements provided by the North American Numbering Plan Billing and Collection Agent (B&C Agent). The B&C WG will investigate/review the performance of the B&C Agent and submit reports at each NANC meeting to fully inform NANC of the B&C Agents performance with respect to the functional requirements. The B&C WG will identify and determine the financial impact, feasibility and/or the appropriateness of initiatives/activities that may need to be included in the budget.

4. Revised Budget & Contribution Factor The NANC approved the preliminary contribution factor of 0.0000171 during the February NANC meeting. The revised factor approved by the NANC on May 7 th was 0.0000181. When initially preparing the budget, the B&C WG and Welch projected the overall industry revenue projection to be down by $1B. In fact, once the preliminary revenue numbers were obtained from USAC (based on the normal process of form 499A calculated results), the overall revenue numbers were down by $14B. Therefore, we need to adjust the industry revenue projection part of the budget used to determine the contribution factor down by an additional $13B. All other budget assumptions remain the same. The new contribution factor has been calculated to be 0.0000181. May 21, 2010B&C WG4

5. July 2010-June 2011 Budget Total projected cost for the NANP Fund is $5,497,882 (including $500,000 surplus) The US carriers are required to contribute $5,401,443 The International Participants (Canada and Caribbean countries) contribute the remaining $96,439

6. May 21, 2010B&C WG6 Contribution Factor Options The first scenario uses up the entire anticipated fund surplus at June 30, 2010 of $1,366,725. The US carriers would be required to fund $4,034,718 with a funding factor of 0.00001712. This option leaves only the $500,000 in the surplus account which is the contingency provision. The second scenario is designed to reduce the surplus by approximately one-half resulting in a contribution factor of 0.000020. This scenario reduces the surplus by $687,320. The total contribution by the US carriers would be $4,714,123. There would be $679,405 excess surplus that could be carried forward to subsidize contributions in the future. The third scenario is designed to leave the surplus in the fund resulting in a contribution factor of 0.0000229. The total contribution by the US carriers would be $5,401,443. There would be $1,366,725 excess surplus that could be carried forward to subsidize contributions in the future. The REVISED scenario still uses up the entire anticipated fund surplus at June 30, 2010 of $1,366,725. The US carriers would still be required to fund $4,034,718 leaving only $500,000 in the surplus account representing the contingency provision. A factor in determining the contribution factor is the total industry revenue. At the time that the budget and the contribution factor were prepared in February, it was estimated that the industry revenue would decline by $1B. Revised information based on the 2010 Form 499A indicated that the industry revenue declined by $14B. As a result the contribution factor needed to be increased to 0.0000181 in order to achieve the same results as the first scenario.
