| |  | | the holdings that "fraud" as used in the federal and state |  | securities statutes is not limited to common law deceit. See |  | generally 7 Louis Loss & Joel Seligman, Securities Regulation 3421- |  | 3448 (3d ed. 1991). |

 |  | |  | 12.  Section 102(10): Guaranteed: Prior Provisions: 1956 Act |  | Section 401(e); RUSA Section 401(a)(1). The 1956 Act definition |  | of "guaranteed" applies generally to payment of "principal, |  | interest, or dividends." The RUSA definition of "guaranteed," |  | which was solely applicable to exempt securities, applied to the |  | guarantee of "all or substantially all of principal and interest |  | or dividends." | 
 | 
 
 
 |  | |  | Section 102(10) follows the 1956 Act approach and applies |  | generally to the guarantee of "all principal and all interest." |  | Any method of guarantee that results in a guarantee of payment of |  | all principal and all interest will suffice including, for |  | example, an irrevocable letter of credit. | 
 | 
 
 
 |  | |  | This definition does not address whether or not a guarantee, |  | whether whole or partial, is itself a security. That issue is |  | addressed by the definition of "security" in Section 102(28). | 
 | 
 
 
 |  | |  | 13.  Section 102(11): Institutional investor: Prior |  | Provisions: RUSA Section 101(5); Securities Act of 1933 Rules |  | 144A and 501(a). | 
 | 
 
 
 |  | |  | Sections 102(11)(A) through (K) are based on Rule 501(a) of |  | the Securities Act of 1933, but do not include the paragraphs of |  | Rule 501(a) that address individuals. Given the significant |  | period of time since Rule 501(a) was adopted, this Act has used a |  | $10 million minimum for several categories of institutional |  | investor rather than $5 million minimum used in Rule 501(a). | 
 | 
 
 
 |  | |  | Section 102(11)(H) concludes with an except clause meant to |  | exclude self-directed plans for individuals from this definition. | 
 | 
 
 
 |  | |  | With respect to the exclusion of Rule 144A(a)(1)(H) from |  | Section 102(11)(M), the substance of Rule 144A(a)(1)(H) appears |  | in Section 102(11)(I), but with a requirement of total assets in |  | excess of $10,000,000. | 
 | 
 
 
 |  | |  | Section 102(11)(O) is meant to reach persons similar to those |  | listed in Sections 102(11)(A) through (N), but not otherwise |  | listed. Under Section 503, if challenged in a proceeding, the |  | burden of proving the availability of an exemption is on the |  | person claiming it. An interpretive opinion may be sought from |  | the administrator under Section 605(d). |
