What is the key idea of the First Principles approach to forecasting PP&E and D&A?

• A. Forecast PP&E requirement directly
• B. Forecast D&A as % of opening PP&E
• C. Use revenue growth to estimate depreciation
• D. Use industry averages for net PP&E

Answer: (A)

Forecasting PP&E and D&A from first principles means building the asset plan from the ground up, driven by how much capacity you actually need. Start with the drivers of capital spending—forecasted production or service demand, capacity utilization, planned upgrades, and maintenance to keep assets operating. Using those, you determine the exact amount of gross PP&E your business must own in each period. That becomes the PP&E you forecast directly. Depreciation then follows from that asset base using the chosen depreciation method and asset lives, rather than being forced into a fixed percentage of opening PP&E or tied to revenue. This links D&A to the real, firm-specific asset plan and capex cycle, rather than relying on historical ratios or external averages.
