Depreciated Replacement Cost is the standard approach under IVS 300 for valuing specialised assets — typically plant, machinery, and purpose-built facilities — where there's no active secondary market to draw comparable sales evidence from.
Why DRC is used for specialised assets
Most valuation methods rely on market evidence: comparable sales or income streams. Specialised plant and machinery — a purpose-built production line, bespoke processing equipment, or facility-specific infrastructure — often has no meaningful secondary market because it's built for a specific operational use and rarely traded independently of the business it serves. DRC works around this by estimating what it would cost to replace the asset's service potential today, then deducting for accumulated depreciation.
The core calculation
- Step 1 — Gross Replacement Cost. Estimate the cost to construct or acquire a modern equivalent asset providing the same service potential, using current pricing for materials, equipment, labour, and installation.
- Step 2 — Physical Depreciation. Deduct for wear and tear based on age and condition relative to useful life, typically informed by inspection and maintenance records.
- Step 3 — Functional Obsolescence. Deduct for the subject asset being less efficient than a modern equivalent — outdated technology, higher operating costs, or lower output capacity.
- Step 4 — Economic (External) Obsolescence. Deduct for factors external to the asset itself — reduced demand for the end product, regulatory changes, or broader market conditions.
Where DRC valuations go wrong
The most common error is treating DRC as a simple age-based depreciation calculation without properly separating functional and economic obsolescence. An asset can be in excellent physical condition (low physical depreciation) but still carry substantial value impairment if it's technologically obsolete or serves a declining market — missing this distinction significantly overstates value.
Adequacy testing
IVS 300 requires DRC valuations to include an adequacy test — checking that the resulting value doesn't exceed what the business could reasonably support given its profitability and the asset's contribution to that profitability. A DRC conclusion that implies an unsustainable return on the underlying asset value signals the calculation needs revisiting.
