To paraphrase the requirements under  Section 2(a)(51) of the Investment Company Act a qualified purchaser means:
“Investments” generally means the following:
Securities, including stocks, bonds and notes, other than securities of an issuer that is under common control with the qualified purchaser.
Real estate held for investment purposes.
Commodity futures contracts, options or commodity futures and options on physical commodities traded on a contract market or board of trade, held for investment purposes.
Physical commodities (e.g., gold and silver), with respect to which futures contracts are traded on a contract market or board of trade, held for investment purposes.
Financial contracts (e.g., swaps and similar individually negotiated financial transactions), other than securities, held for investment purposes.
For an investment company or a commodity pool, any binding capital commitments.
Cash and cash equivalents held for investment purposes. Neither cash used by an individual to meet everyday expenses nor working capital used by a business is considered cash held for investment purposes.
