Subdivisions of apportionments that are made by the heads of agencies, or their designee, to incur obligations within a prescribed amount. Subdivision and distribution of an allotment (e.g., sub-allotments and allocations to operating agencies or installation-level accounting activities) must contain at least the same legal and other limitations applicable to the original allotment. Such subdivisions and distributions may establish additional legal and other limitations applicable to execution of budgetary resources.
