US Carrier Contribution Factor The US carriers are required to contribute $6,005,354 to the Fund by direct contributions and by reduction in the fund surplus. The International Participants (Canada and Caribbean countries) contribute the remaining $128,592 of the projected costs. The options set out below assume the use of the entire anticipated surplus at June 30, 2013 of $453,782 leaving $5,551,572 to be funded by US carriers. This would leave only the $1,000,000 in the surplus account which represents the contingency provision. There are three scenarios for consideration set out below which are based on three different estimates of industry revenue. The first scenario is based on a revenue base of $198B. This option would result in a contribution factor of The second scenario is based on a revenue base of $196B. This option would result in a contribution factor of The third scenario is based on a revenue base of $194B. This option would result in a contribution factor of February 21, 20134

US Carrier Contribution Factor (cont) Revenue Contribution Base The revenue estimates were determined by first reviewing the actual 2011 US carrier revenues reported on the April 1, 2012 Form 499A. Given the economic climate this revenue figure was adjusted downwards based on prior years. Three different revenue estimates are provided. This allows analysis of how the contribution factor is affected given various possible revenue scenarios. This figure will be reviewed at the end of April 2013 when preliminary revenue figures from the 2013 Form 499A will be available. The preliminary revenue figures will be analyzed to finalize the revenue assumption and consequently finalize the contribution factor. February 21, 20135
