(1) The Federal Program Agency incurs interest liability if a State pays out its own funds for Federal assistance program purposes with valid obligational authority under Federal law, Federal regulation, or Federal-State agreement. A Federal interest liability will accrue from the day a State pays out its own funds for Federal assistance program purposes to the day Federal funds are credited to a State bank account.

(2) If a State pays out its own funds for Federal assistance program purposes without obligational authority, the Federal Program Agency will incur an interest liability if obligational authority subsequently is established. However, if the lack of obligational authority is the result of the failure of the State to comply with a Federal Program Agency requirement established by statute, regulation, or agreement, interest liability may be denied. A Federal interest liability will accrue from the day a State pays out its own funds for Federal assistance program purposes to the day Federal funds are credited to a State bank account.

(3) If a State pays out its own funds prior to the day a Federal Program Agency officially notifies the State in writing that a discretionary grant project is approved, the Federal Program Agency does not incur an interest liability, notwithstanding any other provision of this section.

(4) If a State pays out its own funds prior to the availability of Federal funds authorized or appropriated for a future Federal fiscal year, the Federal Program Agency does not incur an interest liability, notwithstanding any other provision of this section.

(5) If a State fails to request funds timely as set forth in § 205.29, or otherwise fails to apply a funding technique properly, we may deny any resulting Federal interest liability, notwithstanding any other provision of this section.
