The real cost of idle plant on your balance sheet

Ask a plant manager what the idle machine in the corner costs and the usual answer is nothing, it is already paid for. That is the accounting of sunk cost, and it is wrong in four specific ways.

Floor space

Industrial floor space in Nairobi is rented or financed. A machine occupying it is consuming that cost whether or not it runs. This is usually the largest single number and the one nobody attributes to the asset.

Insurance and maintenance

Idle plant stays on the insurance schedule. It often stays on a maintenance contract too, because removing it requires someone to make a decision.

Depreciation with no offsetting revenue

The asset continues to depreciate. While it was producing, that charge was matched against revenue. Idle, it is a pure charge.

Audit exposure

A fixed asset register listing equipment that has not operated for three years is a finding waiting to happen. Writing it down requires evidence, and evidence requires a valuation and a disposal record.

Why it gets postponed

Because disposal is nobody specific responsibility, and because the first quote received is usually disappointing. A single scrap merchant quote on a machine with residual production value anchors the seller low, the seller declines, and the machine stays where it is for another year.

What changes the outcome

An independent valuation before anything is offered, then a competitive tender rather than a single quote. The spread between first and second bid on used industrial plant is consistently wider than sellers expect, and that spread is the whole argument for running a process instead of accepting an offer.
