The amount of lost profits can be very high or very low. It all depends upon what assumptions you use. The discloser and the recipient will each have an expert witness to give evidence. Each expert will use arcane financial models to derive a figure for lost profits. Most of the cross-examination concerns the assumptions employed by the expert witnesses.
Lost profits are in the nature of consequential losses.
Direct losses are usually minimal or non-existent. That s why it is so difficult to recover money for breach of a non-disclosure agreement.
