Final answer:
Committing funds based on an assumed rate of appropriation that is higher than what Congress eventually appropriates can lead to an Anti-Deficiency Act violation, as it results in obligating or expending funds in excess of what is legally available.
Step-by-step explanation:
If you obligate funds at the current rate, and Congress appropriates at a lesser rate, it could potentially lead to an Anti-Deficiency Act (ADA) violation. The ADA prohibits federal agencies from obligating or expending funds in excess of the amounts available in their appropriations or beyond their apportionments.
Therefore, if you commit to spending based on an assumed rate of appropriation and it turns out to be less than what is eventually appropriated by Congress, the expenditure would exceed the legal bounds of the available funds, thus violating the ADA.
