Total full-time equivalent employees (FTEs) includes all personnel employed. A FTE is calculated using the reported proportion of full-time hours worked for those who don’t work full-time. For example, an employee who worked 20 hours per week is counted as 0.5 employees if the work week is 40 hours; one who worked full-time for three months out of the year as 0.25 employees; and an employee who year-round works 60 hours per week would count as 1.5 FTEs.
Production FTEs excludes employees that contribute to the fixed costs of the company (e.g., those employees whose employment costs are not directly associated with the variable costs of a project).
