Supplementary estimates often include what are known as “one dollar items”, which seek an alteration in the existing allocation of funds authorized in the main estimates. The purpose of a dollar item is not to seek new or additional money but rather to spend money already authorized for a different purpose within a single department or agency.
Since “estimates” are budgetary items, they must have a dollar value. However, because no new funds are requested, the “one dollar” is merely a symbolic amount.
