Abstract

Security breaches may be a normal risk of doing business, or they may result in economic losses and changes in business valuation. A small number of studies outside the finance literature find mixed results regarding the economic impact of security breaches. In this paper, we examine a large sample to determine whether breaches result in significant economic losses and whether the announcement venue has an impact on business valuation. We find a negative and significant impact on firm value when the breach is announced in one of four major news outlets. When the announcement is elsewhere, the impact is minimal.
