A share or similar equity interest issued by a corporation, business trust, statutory trust, joint stock company, or similar entity is a security. An “investment company security” is a security. “Investment company security” means a share or similar equity interest issued by an entity that is registered as an investment company under the federal investment company laws, an interest in a unit investment trust that is so registered, or a face-amount certificate issued by a face-amount certificate company that is so registered. Investment company security does not include an insurance policy or endowment policy or annuity contract issued by an insurance company. An interest in a partnership or limited liability company is not a security unless it is dealt in or traded on securities exchanges or in securities markets, its terms expressly provide that it is a security governed by this title, or it is an investment company security. However, an interest in a partnership or limited liability company is a financial asset if it is held in a securities account. A writing that is a security certificate is governed by this title and not by Title 3 of this article, even though it also meets the requirements of that title. However, a negotiable instrument governed by Title 3 of this article is a financial asset if it is held in a securities account. An option or similar obligation issued by a clearing corporation to its participants is not a security, but is a financial asset. A commodity contract, as defined in § 9-102(a)(15) of this article, is not a security or a financial asset. A document of title is not a financial asset unless § 8-102(a)(9)(iii) applies.
