• Total projected cost for the NANP Fund is $5,857,267 
 
(including $750,000 contingency fund).
• The US carriers are required to contribute $5,762,323 to the

• The International Participants (Canada and Caribbean 
 
countries) contribute the remaining $94,944.

Contribution Factor Options
• The first scenario
 
uses the entire anticipated fund surplus at June 30, 
 
2011 of $1,141,441.  The US carriers would be required to fund 
 
$4,620,882 with a funding factor of 0.0000220.  This option leaves only 
 
the $750,000 in the surplus account which represents the contingency 
 
provision. Consensus was reached by the B&C WG to use this first 
 
scenario.
• The second scenario
 
is designed to reduce the surplus by approximately 
 
one?half resulting in a contribution factor of 0.0000247. This scenario 
 
reduces the surplus by $570,720. The total contribution by the US carriers 
 
would be $5,191,603. There would be $570,721 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 0.0000274.  The total contribution by the US 
 
carriers would be $5,762,323. There would be $1,141,441 excess surplus 
 
that could be carried forward to subsidize contributions in the future.
