CHANGING ROLE AND SCOPE OF VENTURE CAPITAL liquidity for investors, including insiders. Going public at the right time also provides maximum cash for minimum dilution of equity ownership by the existing investors. Timing of an issue is very important. An illustration of timing is pre- sented in a study done by Howard (1973). During a 22-month period, (through October 1972), 452 venture companies filed initial registration statements. Of the 234 ventures who filed registrations in 1971, 97 had gone public by October 1972, a period in which the public markets were good and the Dow Jones Industrial index exceeded 900. The successes of 1972 led more companies to retain underwriters for offerings of securities in 1973. Through October 1973, 90 ventures filed registrations. Only six were successful. Another six were effective, but the best-efforts underwriting was not completed. Of the remaining firms un- der study, 16 withdrew their registration and 62 remained in registration, hoping for a new issue market rally. RESEARCH AND DEVELOPMENT LIMITED PARTNERSHIPS (RDLPs) A source of financing that has rivaled the stock market in size is a type of investment known as an R&D limited partnership. This allows individuals or organizations to invest in a company's research and development and to write off that money as expenses. The investors become limited partners and are entitled to receive royalty payments from future sales of products. Part or all of these royalties are in turn taxed as capital gains, offering an added attraction to this kind of investment. Since their inception, more RDLPs have been devoted to biotechnology than any other technology segment. According to a draft of a new study that the New York University (NYU) Center for Science and Technology Policy carried out for the National Science Foundation, through the end of last year RDLPs in biotechnology raised $663 million-fully 27 percent of the $2.5 billion total raised through RDLPs (Klausner, 1986). As a compar- ison, the study, "RDLPs and Their Significance for Innovation," notes that biotech has attracted only about 3 percent of all venture capital support. The report estimates that 85 percent of all funds raised by RDLPs actually goes to research, and that this financing vehicle has sponsored about $0.5 billion in R&D annually since 1982 (Klausner, 1986). The bottom line is that RDLPs are here to stay for biotechnology. The NYU Center draft concludes, "A company with a solid reputation and
