[0] IG O [IPC Comments] The IPC does not object per se to the use of a reduced fee scheme, but is skeptical that the positive effect of such a scheme will outweigh the negative impact of an underfunded applicant's inability to meet the selection criteria set by ICANN. We strongly recommend that any graduated fee structure be viable and significant enough to ensure compliance with appropriate registry selection criteria, as well as eliminate bad-faith actors who might seek to pay a minimal entry fee and then conduct unscrupulous activities. [Implementation Guideline] 
ICANN may put in place a fee reduction scheme for gTLD applicants from economies classified by the UN as least developed.
