Your client is a gun manufacturer. Due to the tragic nature of gun violence, many citizens have threatened to protest against your client. However, your client's manufacturing plant is located in rural Montana, so protesters cannot conveniently get there to stage a public protest.
In preparing an SEC filing for this client, you disclosed the addresses of its Montana manufacturing plant and its company headquarters in downtown Seattle. Over 80 top company executives work at company headquarters. Your disclosure led to a large protest rally in downtown Seattle that created adverse publicity for your client. Your client now is upset because, historically, it only disclosed the address of its rural Montana plant in public filings. The SEC form, however, clearly required that a company's "principal places of business" be disclosed.
Did you violate the duty of confidentiality?
