A new laptop built by my company is turned on during a plane flight and used to edit documents. The laptop battery explodes. The plane crashes and burns with everyone trapped inside.

Now, should we initiate a recall?

Take the number of laptops in the field (A) multiply it by the probable rate of failure (B) then multiply the result by the average out of court settlement (C). A times B times C equals X. If X is less than the cost of the recall, we don't do one.
