Charles Whiteknife: Do you know what "fiduciary responsibility" means?

Cooper Howard: Fiduciary responsibility?

Charles Whiteknife: Yeah.

Cooper Howard: No, I have no f**king idea. I play a cowboy for a living.

Charles Whiteknife: Okay. So, the U.S. government has outsourced the survival of the human race to Vault-Tec. Vault-Tec is a private corporation that has a fiduciary responsibility to make money for its investors. And how does it make money? By selling vaults.

Cooper Howard: That's called capitalism, Charlie.

Charles Whiteknife: But they can't sell vaults if these peace negotiations go through. So Vault-Tec has a fiduciary responsibility to make sure that it don't work out.
