Exempt reporting advisers


Exempt Reporting Advisers ("ERA") are investment advisers that are not required to register as investment advisers because they rely on certain exemptions from registration under sections 203(l) and 203(m) of the Investment Advisers Act of 1940 and related rules. Certain state securities regulatory authorities have similar exemptions based on state statutes or regulations. An ERA is required to file a report using Form ADV, but does not complete all items contained in Form ADV that a registered adviser must complete. Other state securities regulatory authorities require an ERA to register as an investment adviser and file a complete Form ADV. Below are the regulators with which an ERA report is filed.

Red Flags


Disclosures can be potential red flags, including customer disputes, regulatory fines, employer terminations, bankruptcies, judgments, liens, or certain criminal activities.

Check for any disclosures as part of your thorough research when choosing an advisor.
