For much of the last century, as public equity markets have grown, the choice for owners of private businesses that had growth potential was a simple one. Stay private, with limited access to equity capital or go public? In making the decision, the owner weighed the pluses and minuses of a public offering. On the plus side, liquidity increases and you have access to far more capital, generally at a lower cost, since the investors buying your equity tend to be more diversified (and thus willing to overlook a portion of the risk in your company). On the minus side, you risk loss of control (if not right away, but at some point in time in the future; remember the cautionary tale of Steve Jobs and Steve Wozniak being forced out of Apple in the 1980s) and you also have far more stringent corporate governance rules (think Sarbanes-Oxley) and information disclosure requirements. The venture capital market eased the transition, by allowing small firms that were not ready to go public to raise equity from private investors, albeit at a higher cost than they would pay in public markets.
To capture how the diversification status of the potential equity investor affects the cost of equity, I developed a scaled measure of beta a couple of decades ago, with the beta changing as a function of the diversification status:
Thus, a company with a market beta of 0.8 (to a diversified investor) can have a total beta of 2.4 (to a completely undiversified owner) and 1.6 (to a partially diversified venture capitalist). I have a data set that summarizes my estimates of market and total betas by sector for US companies that you can take a look at, if you are interested.
In the last few years, there have been two developments that have muddied the waters and changed the dynamics of whether and when firms go public. The first is the development of a private share market, where shares of private business can be traded by their owners, granting private businesses many of the advantages that they would have as public companies without much of the information disclosure/monitoring requirements that come with being public. Facebook is perhaps the most prominent example of a private business that has access to as much capital as almost any public company through this market. The second is the insidious route adopted by some non-US (primarily Chinese) private businesses that have bought small publicly traded US companies and used these companies as shell vehicles to gain access to public equity.
In both cases, equity owners of these businesses are badly served, since they own portions of private businesses without the right to access information or influence management (that they at least in theory have with public companies). In know that the obvious fix to both these problems is to regulate these options, either by extending public company scrutiny to firms in the private share market or by barring trading in the market. However, the people who buy equity in Facebook in the private share market or a Chinese shell company are doing so voluntarily. Presumably, they are pricing in their concerns (or lack thereof) into what they pay and deserve to get whatever upside (or downside) they get from their investments. I will not envy them their returns but I will certainly not shed any tears for their losses, either. So, Facebook equity investors, I hope you make money on your investments.. but with Mark Zuckerberg as your lead partner, you should perhaps consult the Winkelvoss twins on how well your interests will be served.
