How is my damage respectively the amount in dispute calculated in legal proceedings?

Your loss cor­res­ponds to the amount in dis­pute in the law­suit and is made up of the pur­chase value of your se­cur­it­ies, in­clud­ing ac­quis­i­tion costs and any com­mis­sions paid. To mit­ig­ate your loss, any di­vidends re­ceived and, if you have sold the se­cur­it­ies, the net pro­ceeds of the sale must be deducted.
