I know that the issue has been resolved but since I asked Scottrade about it, here's their response:
Dear ____ ___:
Thank you for bringing this to our attention.
We get our information from an outside vendor, not the FINRA Daily List. In most cases, we do not report dividend information on OTC stocks; and I was not able to verify the dividend with the Sunset Island Group Inc. (SIGO) Investor Relations Department.
I have forwarded your email to our vendor to have them research this further.
We greatly appreciate your patience.
Thank you for choosing Scottrade. Please let us know if we may be of further assistance.
Your feedback is important to us. Please let us know how we did today by clicking on the survey link below.
Sincerely,
