<prompt> Human: Or any other scenario I may not know about. The merger scenario seems pretty self explanatory. Probably similar to what happened to my Sallie Mae student loan recently. But I have literally no idea how bankruptcy works. Is this part of the risk I assume by investing?  <response>: Vanguard is not a publicly-traded corporation that could merge with or be bought or sold by any private entity.Vanguard cant go bankrupt unless all the funds go to zero, in which case money is worthless anyway because the apolcalypse has occurred.
