CEO and chairman of Goldman Sachs (GS  ) David Solomon has defended the investment bank's hand in the underwriting of WeWork's failed IPO, stating "I'm not sure that we got it so wrong...There were things that were right, there we things that were wrong," during a panel valuing 'unicorns' at Davos on Tuesday.

"The banks weren't valuing. The way the process of an IPO works when you're a bank is you're invited in by a company, it's a private company, their numbers aren't public, they give you a model. You say to the company: well, if you can prove to us that the model actually does what this does, then it's possible it could be worth this in the public markets...[private companies are] not held to the same standard [as public companies] around producing information...and that's an issue."

The bank revealed back in October that the failed IPO and write-down had cost the bank upwards of $80 million.
