Answer:
a. Some expenses reported in the statement of activities do not require the use of current financial resources and are not reported as expenditures in the fund-level statements.
Explanation:
Governments maintain a statement of activities that are carried out, and fund-level statements are also maintained to track expenses of government.
When there is a disparity between the two, a plausible explanation will be that some expenses reported in the statement of activities do not require the use of current financial resources and are not reported as expenditures in the fund-level statements.
For example some long term project that is carried out by the government may be treated by creating a budget. These expenses will not be recognized in the current expenses that make up fund-level expenses.
