NOTES:
The figures reported for each fiscal year represent the current organizational unit structure and may not always match the figures published in previous reports due to organizational changes and unit re-configurations. Additionally, these figures represent actuals as per management accounting and may differ from figures presented for financial accounting and reporting purposes that are in compliance with the United States' Generally Accepted Accounting Principles.
Beginning in fiscal 2018, the budget and related expenditures related to changes in the non-salary staff costs recovery rate charged to units were moved from centrally-managed accounts to corresponding organizational units. This contributed to the decrease in centrally-managed accounts and programs in fiscal 2018 and corresponding increases in other units. The changes entailed increasing the non-salary staff costs recovery rate for Headquarters-appointed staff from 50 percent to 70 percent and introducing a recovery rate of 45 percent for country office?appointed staff so as to more accurately reflect unit and product costs.
