"Generally, the homeland security appropriations bill includes all annual appropriations for the Department of Homeland Security (DHS), providing resources to every departmental component. Table 1 and Figure 1 show DHS's new discretionary budget authority enacted for FY2015 and requested by the Administration for FY2016, as well as the funding levels provided in the Senate-reported and House-reported homeland security appropriations bills broken down by component--from largest to smallest appropriations request. Total discretionary appropriations (as opposed to mandatory appropriations or other revenue available without annual congressional action) in Table 1 do not include resources provided through adjustments under the Budget Control Act (BCA) in the individual component lines. These are accounted for separately from the total discretionary appropriations and are displayed at the bottom of the table. As the table and figure reflect new discretionary budget authority, neither appropriated mandatory spending nor rescissions of prior-year budget authority are reflected in the component totals."
