(1) In this chapter, unless the context otherwise requires:

1. (a) A "certificated security" is a share, participation, or other interest in property of or an enterprise of the issuer or an obligation of the issuer which is

   1. (i) represented by an instrument issued in bearer or registered form;
   2. (ii) of a type commonly dealt in on securities exchanges or markets or commonly recognized in any area in which it is issued or dealt in as a medium for investment; and
   3. (iii) either one of a class or series or by its terms divisible into a class or series of shares, participations, interests, or obligations.

2. (b) An "uncertificated security" is a share, participation, or other interest in property or an enterprise of the issuer or an obligation of the issuer which is

   1. (i) not represented by an instrument and the transfer of which is registered upon books maintained for that purpose by or on behalf of the issuer;
   2. (ii) of a type commonly dealt in on securities exchanges or markets; and
   3. (iii) either one of a class or series or by its terms divisible into a class or series of shares, participations, interests, or obligations.
3. (c) A "security" is either a certificated or an uncertificated security. If a security is certificated, the terms "security" and "certificated security" may mean either the intangible interest, the instrument representing that interest, or both, as the context requires. A writing that is a certificated security is governed by this chapter and not by Chapter 7 of this title, even though it also meets the requirements of that chapter. This chapter does not apply to money. If a certificated security has been retained by or surrendered to the issuer or its transfer agent for reasons other than registration of transfer, other temporary purpose, payment, exchange, or acquisition by the issuer, that security must be treated as an uncertificated security for purposes of this chapter.

4. (d) A certificated security is in "registered form" if

   1. (i) it specifies a person entitled to the security or to the rights it represents; and
   2. (ii) its transfer may be registered upon books maintained for that purpose by or on behalf of the issuer or the security so states.
5. (e) A certificated security is in "bearer form" if it runs to bearer according to its terms and not by reason of any indorsement.

(3) A "clearing corporation" is a corporation registered as a "clearing agency" under the federal securities laws or a corporation:

1. (a) at least ninety percent of whose capital stock is held by or for one or more organizations, none of which, other than a national securities exchange or association, holds in excess of twenty percent of the capital stock of the corporation, and each of which is

   1. (i) subject to supervision or regulation pursuant to the provisions of federal or state banking laws or state insurance laws,
   2. (ii) a broker or dealer or investment company registered under the federal securities laws,
   3. (iii) is a national securities exchange or association registered under the federal securities laws; and
2. (b) any remaining capital stock of which is held by individuals who have purchased it at or prior to the time of their taking office as directors of the corporation and who have purchased only so much of the capital stock as is necessary to permit them to qualify as directors.
