The NNI's annual budget supplements provide supplemental information to the President’s annual budget. They also serve as the annual report on the NNI called for in the 21st Century Nanotechnology Research and Development Act. The reports summarize NNI programmatic activities for the two previous fiscal years, as well as the address plans for the upcoming fiscal year.
The NNI Strategic Plans describe the NNI vision and goals and the strategies by which these goals are to be achieved, including specific objectives within each of the goals, as called for in the 21st Century Nanotechnology Research and Development Act. These documents describe the NNI investment strategy and the investment categories, known as the program component areas (PCAs), used in the annual NNI budget crosscut. Per the Act, the Strategic Plan is updated every four years, replacing the previous version.
