26. A purchaser of a certificated security is considered to have notice of an adverse claim if1° the security certificate, whether in bearer form or registered form, has been endorsed “for collection” or “for surrender” or for some other purpose not involving a transfer; or
2° the security certificate is in bearer form and has on it an unambiguous statement that it is the property of a person other than the transferor.
The mere writing of a name on a security certificate does not by itself constitute an unambiguous statement that the security certificate is the property of a person other than the transferor.
