When any US stock is acquired this is what the response to me from the SEC was...
Dear Mr.
Thank you for contacting the SEC.
When a person or group of persons acquires beneficial ownership of more than 5% of a class of a company?s equity securities registered under Section 12 of the Securities Exchange Act of 1934, they must file a Schedule 13D (or in some cases, Schedule 13G) with the SEC. More information about this requirement is available on the SEC website at
http://www.sec.gov/answers/sched13.htm.
In addition, a company's officers and directors, and any beneficial owners of more than ten percent of a class of the company's equity securities registered under Section 12 of the Securities Exchange Act of 1934, must file a statement of ownership regarding those securities with the SEC. Information about this requirement can be found on our website at http://www.sec.gov/answers/form345.htm.Institutional investment managers who exercise investment discretion over $100 million or more in Section 13(f) securities must report their holdings on Form 13F with the SEC. (See
http://www.sec.gov/answers/form13f.htm.)
I hope this information will prove helpful to you.
Sincerely,
BONNIE C DAILEY
