The pages in this document appear in the summary of the Office of the Director of National Intelligence's multivolume FY 2013 Congressional Budget Justification — the U.S. intelligence community's top-secret "black budget." It covers many of the high-profile agencies, such as the Central Intelligence Agency and the National Security Agency, as well as lesser-known programs, including those within the Treasury, State and Energy Departments.

See detailed breakdowns of how the U.S. government allocates resources across the intelligence community and within individual agencies in the annotated pages below.
