Don't worry - it's all one big security:
http://caselaw.lp.findlaw.com/scripts/getcase.pl?navby=CASE&court=US&vol=328&page=293"Section 2(1) of the Act defines the term 'security' to include the commonly known documents traded for speculation or investment. 3 This definition also includes 'securities' of a more variable character, designated by such descriptive terms as 'certificate of interest or participation in any profit-sharing agreement,' 'investment contract' and 'in general, any interest or instrument commonly known as a 'security." The legal issue in this case turns upon a determination of whether, under the circumstances, the land sales contract, the warranty deed and the service contract together constitute an 'investment contract' within the meaning of 2(1). An affirmative answer brings into operation the registration requirements of 5(a), unless the security is granted an exemption under 3(b), 15 U.S.C.A. 77c(b). The lower courts, in reaching a negative answer to this problem, treated the contracts and deeds [328 U.S. 293, 298] as separate transactions involving no more than an ordinary real estate sale and an agreement by the seller to manage the property for the buyer.
The term 'investment contract' is undefined by the Securities Act or by relevant legislative reports. But the term was common in many state 'blue sky' laws in existence prior to the adoption of the federal statute and, although the term was also undefined by the state laws, it had been broadly construed by state courts so as to afford the investing public a full measure of protection. Form was disregarded for substance and emphasis was placed upon economic reality. An investment contract thus came to mean a contract or scheme for 'the placing of capital or laying out of money in a way intended to secure income or profit from its employment.' State v. Gopher Tire & Rubber Co., 146 Minn. 52, 56, 177 N.W. 937, 938. This definition was uniformly applied by state courts to a variety of situations where individuals were led to invest money in a common enterprise with the expectation that they would earn a profit solely through the efforts of the promoter or of some one other than themselves.
By including an investment contract within the scope of 2(1) of the Securities Act, Congress was using a term the meaning of which had been crystallized by this prior judicial interpretation. It is therefore reasonable to attach that meaning to the term as used by Congress, especially since such a definition is consistent with the statutory aims. In other words, an investment contract for purposes of the Securities Act means a contract, trans- [328 U.S. 293, 299] action or scheme whereby a person invests his money in a common enterprise and is led to expect profits solely from the efforts of the promoter or a third party, it being immaterial whether the shares in the enterprise are evidenced by formal certificates or by nominal interests in the physical as ets employed in the enterprise. Such a definition necessarily underlies this Court's decision in Securities Exch. Commission v. C. M. Joiner Leasing Corp., 320 U.S. 344 , 64 S.Ct. 120, and has been enunciated and applied many times by lower federal courts. 5 It permits the fulfillment of the statutory purpose of compelling full and fair disclosure relative to the issuance of 'the many types of instruments that in our commercial world fall within the ordinary concept of a security.' H. Rep.No.85, 73rd Cong., 1st Sess., p. 11. It embodies a flexible rather than a static principle, one that is capable of adaptation to meet the countless and variable schemes devised by those who seek the use of the money of others on the promise of profits."
