5. Contribution Factor Revenue Contribution Base The revenue estimates were determined by first reviewing the actual 2014 US carrier revenues reported on the April 1, 2014 Form 499A. A range of revenue estimates were 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 2015 when preliminary revenue figures from the 2015 Form 499A will be available. The preliminary revenue figures will be analyzed to finalize the revenue assumption and consequently finalize the contribution factor. Please note this factor will be an increase over last year. The overall revenue base continues to drop causing the contingency factor to rise. We are also collecting for an additional 3 months this year in order to align our funding year to the federal fiscal year in 2016. 5

6. Budget/Contribution Factor The options provided subsidize the funding requirement by using up all of the surplus fund balance. Balance to be funded $8,013,821 Anticipated surplus (at June 30) per Jan 15 NANP report ($1,360,273) Net US Carrier Contribution requirement $6,653,548 This incudes a $500,000 Contingency fund The contribution factor will be within this range Contribution Factor If revenue base is $180B ……………………………………….0.0000370 If revenue base is $172B ……………………………………… 0.0000387 6
