A change in the allocation of resources in a budget. Resources are programmed with the budget, and a change is another programming, or a reprogramming. In practice, a change is called a reprogramming if it exceeds certain thresholds. An approved budget usually consists of specific amounts of money appropriated for specific accounts. Within each account there may be additional restrictions on what the money may be used for. A reprogramming is whenever funds need to be changed in ways that would violate any of the conditions of the appropriation law. The law or the report associated with the law usually specifies what is considered a reprogramming and the conditions under which reprogramming may be carried out.
