Average total life span of the Property, Plant and Equipment. Average age of Property, Plant and Equipment. Average remaining life of Property, Plant and Equipment. b) Discuss the importance of these ratios for the analysis of Boubyan Petrochemicals. Use the below formulas in the calculation of the ratios asked in (a). Average total life span of plant and equipment = Gross plant and equipment / Current year depreciation expense Average age of plant and equipment = Accumulated depreciation / Current year depreciation expense Average remaining life of plant equipment = Net plant and equipment / Current year depreciation expense
