Explanation

Valentina's actions violated the Standard relating to preservation of confidentiality by adding Mitchell's email address to the donor database because:

1. Confidential client information: Mitchell's email address was obtained from BSW's records, which constitutes confidential employer information.

2. Unauthorized use: She used this confidential information for personal purposes (charity volunteering) without proper authorization.

3. Standard III(E) - Preservation of Confidentiality: This standard requires members to keep information about clients, employers, and former employers confidential unless:

   • The information concerns illegal activities
   • Disclosure is required by law
   • The client or employer permits disclosure
   • The information is already public

4. No consent obtained: She failed to obtain Mitchell's consent before adding his email to the charity's database.

5. Invitation to dinner: This action alone does not violate confidentiality standards, as it doesn't involve disclosing confidential information.

Key takeaway: CFA professionals cannot use confidential client information obtained through their employment for personal purposes, even for charitable activities, without proper authorization and consent.
