Final answer:
No, the statement is False. Non-convertible bondholders or preferred stockholders are not considered insiders and do not have access to non-public information.
Step-by-step explanation:
No, the statement is False. An investor who holds non-convertible bonds or preferred stock of a company is not an insider in terms of having access to non-public information. Insiders typically include managers, directors, and major shareholders who have access to confidential information about the company. Non-convertible bonds and preferred stock are generally available to the public and do not give the holder access to non-public information.
