What? Are you saying that you think there needs to be some kind of post-mortem because the investors might end up paying less income tax then they would have in some unlikely alternate reality where the deal was a success? That doesn't make any sense at all.
I'm not GP, but perhaps something like the following would be a reason (investigation might be a more accurate term than post-mortem in that case).
>In October 2020, Vista's CEO Robert F. Smith and investor Robert T. Brockman were named in a tax evasion case.[33][34] That month, Smith signed a non-prosecution agreement with the IRS, agreeing to pay $139 million and testify against Brockman.[33]
