• Floor R/U Ratio = (Floor Rentable Area) / (Floor Usable Area)
• Basic Rentable Area = (Usable Area) x (Floor R/U Ration)
• Building R/U Ratio = (Building Rentable Area) / (Building Rentable Area - Basic Rentable Area of Building Common Area)
• Rentable Area = (Basic Rentable Area) x (Building R/U Ratio)
• R/U Ratio = (Floor R/U Ratio) x (Building R/U Ratio)
• Rentable Area = (Usable Area x Combined R/U Ratio)
