This legislation attempted to eliminate provisions of the 1940 Act that created unnecessary disincentives to private equity investment extant in the regulatory framework of the time. Open-end investment companies mutual funds could not by definition invest to a meaningful extent in small businesses in light of their fundamental need for liquidity; registered closed-end investment companies, for their part, were considered unappealing as venture capital funds in light of their limitations on borrowing and inability to compensate management with equity, a venture capital sine qua non. The centerpiece of the 1980 Amendments was the advent of a new category of closed-end investment company subject to the 1940 Act, but operated as a venture capital enterprise – the business development company, or BDC.
