When a nonprofit is awarded a grant, then the organization must wait three years before reapplying to Impact 100 for another grant.  The 3 year period for grant recipients to re-apply begins the year that the grant is awarded no matter if the grant money is distributed lump sum or via installment payments according to the terms of the grant agreement.
(Example: Nonprofit X received grant in 2018.  Nonprofit X would be able to re-apply for the 2022 grant cycle. Year 1 = 19, Year 2 = 20, Year 3 = 21).
