4. 2005/2006 Welch & Co.

B&C WG

5. Budget for period July 2007 – June 2008 • Working with the proposed budget created by Welch & Co. to arrive at a reasonable Budget and Fund Size in order to ensure sufficient funds are available for anticipated disbursements. • The current proposed total projected cost for the NANP fund is $7,430,374, with a $1M contingency provision built in. B&C WG

6. Proposed Contribution Factor for period July 2007 – June 2008 The B&C WG is responsible for the review and ultimately the approval process for the formula and calculation of the contribution factor. Option 1 is designed to exhaust the entire anticipated fund surplus. (June 30, 2007 of $1,990,084) The US carriers would be required to fund $4,530,185 with a funding factor of 0.0000193. This option leaves only the $1,000,000 in the surplus account which is the contingency provision. Option 2 is designed to arrive at a contribution factor of exactly 0.000020. This scenario reduces the surplus by $1,829,430 and the total contribution by the US carriers would be $4,690,839. There would be $160,654 excess surplus that could be carried forward to subsidize contributions in the future. Option 3 is calculated to arrive at a contribution factor of exactly 0.000021. This scenario reduces the surplus by $1,594,888 and the total contribution by the US carriers would be $4,925,381. There would be $395,196 excess surplus that could be carried forward to subsidize contributions in the future. B&C WG
