Which of the following is NOT considered an additional source of nonappropriated funds (NAF)?

In the context of nonappropriated funds (NAF), surcharges are typically considered a regular part of operations or pricing strategies within Air Force services, rather than an additional source. Nonappropriated funds are generated through various means, and additional sources include grants, donations, and fundraisers, all of which are aimed at enhancing program resources and offerings.

Grants often provide external funding support for specific projects, while donations are contributions from individuals or organizations that can help support various programs. Fundraisers are events or activities organized to generate revenue beyond standard operations. Since surcharges are integrated into established pricing models and do not represent an external or additional funding source, they do not fit the classification of being an additional source of nonappropriated funds.
