Yes, funding amounts negotiated in an AFA may be adjusted under the following circumstances:
(a) Congressional action.
(1) Increases/decreases as a result of Congressional appropriations and/or a directive in the statement of managers accompanying a conference report on an appropriations bill or continuing resolution.
(2) General decreases due to Congressional action must be applied consistently to BIA, self-governance Tribes/Consortia, and Tribes/Consortia not participating in self-governance.
(3) General increases due to Congressional appropriations must be applied consistently, except where used to achieve equitable distribution among regions and Tribes.
(4) A Tribe/Consortium will be notified of any decrease and be provided an opportunity to reconcile.
(b) Mistakes. If the Tribe/Consortium or the Secretary can identify and document substantive errors in calculations, the parties will renegotiate the amounts and make every effort to correct such errors.
