First up are some emails related to the surprising lack of big VC liquidity events.

Peter: "It's possible that this all actually works to LPs' advantage. The traditional PE/VC model is actually a bit broken. You're incentivized to deploy the capital relatively quickly; then if you get a couple of doubles or triples, you flip them quickly to print a brilliant IRR to raise your next fund; and you let the dogs fester in the portfolio for years. That's not what LPs really want. They care about MOIC not IRR. It's actually good to hold your winners for longer and to add capital to a winning investment."

LP: "Thank you for writing this. We have a lot of confidence in most of our current VC fund investments but the time to exit is becoming unreasonably long. We're also not pleased by what seems to be a much more hands-off attitude by our GPs, as if they don't want to risk offending the entrepreneurs we are funding."

Josh: “Has something changed fundamentally, where (often) younger private company management teams would rather stay private and therefore more nimble by not succumbing to public market regulations/scrutiny and quarterly analyst oversight (which is effectively what Jack Ma came out and said publicly)? Hypothetically, if you’re an investor in AirBnB or Uber right now, would you rather the liquidity that comes with an IPO, or could you envision a scenario where once growth plateaus and the company is mature, you would prefer the possibility of dividends as a means of liquidity rather than public company stock? If LPs in these funds are longer-term time horizon investors, where do they see more value?”

• There also were a lot of emails related to an earlier piece that took issue with the notion that private market valuations are inferior to public market valuations. George: "Agree with your conclusion re the public market compare. And as for the 'made up' valuations, I feel it's almost a defense mechanism for managers that can't invest in private companies. Oh look at those made up valuations (that I wish I could apply to my P&L)."

Marc: "Valuation is subjective and difficult at best and its accuracy/inaccuracy is ONLY appreciated retrospectively."

Brian: "While I would never describe the public market as perfect, I do think it is generally the best judge of value at a point in time, with the freely available information at that time. Venture-backed companies and fast-growing public are both subject to considerable risk, uncertainty, and hard-to-predict futures, so both markets will inevitably have large valuation swings (one way or another). That said, the public market is obviously much, much larger and generally has more information, transparency, and liquidity. Public valuations are also influenced by derivatives, such as short positions, which have no real comparable mechanism in the private markets. This leads to more accurate pricing (theoretically anyway). Of course there is always the chance, that the future brings new information that makes the old price look silly, whether public or private."

• S talks Ifty Ahmed: "If I were an LP, I'd really be wondering if there should be a VC exemption from full registration. I suppose it's possible that this could have happened at a full registrant, but I'd be surprised -- I think that the requirements of registration and the threat of enforcement result in better internal controls than Oak evidently had. Why was a senior investment partner in the middle of what is normally a back-office process, handling document review and wire instructions?That said, even absent full SEC registration, why didn't the auditors catch this? I noted from their filings that they have a regional audit firm vs a Big 4, but the regional firm should have unearthed these weak controls."

• Have a great weekend...
