GASB requires that revenues and expenses be separated between operating and nonoperating. Operating revenues and expenses result from providing goods and services. Nonoperating activities are those outside the activities that are part of the operating activities of the institution. Most government appropriations are nonoperating because they are not generated by the operations of the institution. Investment income is nonoperating in most instances because institutions are not engaged in investing as an operating activity. Gifts are defined as nonoperating. Nonexchange transactions generate nonoperating revenues.
