The HasAlternateUSSection12Registration property exists to capture an interpretive update from aosphere, which is outlined in Section 3.5(g) of the U.S. memo and Question 101.03 of the SEC's Q&A on 13D and 13G reporting.

In summary, it is possible for non-U.S. securities that are traded outside of the United States to be disclosable under 13D/G if the particular class is held on deposit underlying an ADR, which is Section 12 registered. In addition, there are cases where a security (foreign or domestic to the U.S.) is registered under Section 12 by other means besides being listed on a U.S. National Securities Exchange. The aosphere memo for the United States describes "alternate means of registration" in Section 3.5(a), 'Section 12 Registration', and related footnotes.

If you hold securities that are registered under Section 12 and are therefore reportable, please indicate this by setting the HasAlternateUSSection12Registration property to "true."

Please note that since this is not an exclusionary property, we will require it to be set for every non-derivative instrument in your file. If you set a data override to "false," you will not receive missing data. Defaulting this to false will also ensure the 13D/G rules provide their checks as if your firm hadn't taken advantage of this nuance. While this property is tricky, we discourage clients from defaulting it as we want you to set it purposefully.
