Mining Business Interruption Insurance and the Principle of Indemnity

A contradiction?

How can a mine claim for lost production when the ore is not lost and will be mined?

Why does a mining company need to purchase business interruption insurance if production will be made up at some later date?

Typically, miners purchase business interruption insurance to protect their earnings and cash flow during some specified maximum period affected by an insured incident.  This allows them to continue to protect their assets, their workforce, their earnings and their share price during an insured outage period.

But they will eventually mine the ore at the end of the original mine life and will sell the resulting metals at a profit.  So is this double indemnity?

Well, like most things, that depends.  In a perfect mining world, yes, they will eventually sell the same metal on the open market that they already sold in theory to an insurance company.

In a mine that has a ten year remaining life and has a six month insured outage, what has been lost?

The entire mine plan will be pushed back six months and the mine will remain open another six months.  All metal will be recovered but it will be sold at a different price in ten years than it would have been sold now.   An additional six months of site operations costs will be incurred ten years from now.

So, we could wait ten years to measure the actual differentials on revenue and costs.  That would not be helpful for any mining company’s cashflow, earnings or share price.

We could forecast metal prices in ten years.  If I could do that accurately, I would be quite wealthy.  And we would need to forecast all of the operating costs ten years from now, including labour, utilities, fuels, equipment and also factor in the impact of technology change, environmental laws and employment laws on all of these costs.  Quite a daunting task.

And finally, can we even predict whether a mine will be operating ten years from now.  Might it be closed down by a government regulation, an environmental law or some physical hazard?  Or could it be a voluntary closure due to metal prices and dramatic cost increases?  Or might the metal not even be required for societal use due to technological advancements?

So in addition to forecasting prices and costs ten years from now, we would have to factor in a wide variety of operational, societal and economical risks that could hamper or close operations.

So that won’t work.

Instead, we measure the loss and financial impact in a relatively short period, usually one year.

So we close the book on the impact on years 2 through 10 and focus on the impact on year one.  Instead of attempting to measure the true impact over the ten years of the mine, we instead choose to take a more narrow measure.

How was production and revenue affected?  How was the mine plan changed?  How much revenue was lost?

What savings in costs were experienced? Not just the obvious variable costs such as drilling, blasting, chemicals and fuels but other costs such as vehicle maintenance, grinding media, wear parts on conveyors, and certain labour costs.

If the event resulted in destruction of depreciable assets, we also consider the possibility of a cessation or savings in depreciation.

We have to be careful not to let the accounting methodology used by the mine affect our consideration of a cost.  If maintenance of the shovel and bucket fleet is considered fixed in the internal accounting system, do we not consider potential savings?  We should analyze the various maintenance costs and identify the costs that will vary with usage and wear such as shovel plates, guards and teeth and truck tires for example.

If the mine amortizes certain fixed assets using a unit of production basis, do we automatically consider these costs variable?  Not necessarily.  Amortization of a mill at a site may be on a unit of production basis, particularly if the ore body size is clearly known.  But are we entitled to take a savings related to mill depreciation against the revenue from the production shortfall.  Probably not.

My next post on mining business interruption will consider the handling of deferred stope development cost.
