If they put up $400,000 in cash for the bail, they get it all back. But if they bought a bail bond, which is what most people do, they pay a premium of 10%, and that money is gone forever. It's what the bailbondsman gets for his risk in bonding the $400,000, which will be lost to him if the accused skips out.
I'm not aware of how they got the bond money put up, and I may have assumed they bought a bond when they didn't. If either they or someone else put up 400 grand, there is no 10% premium.
From what I understand the "accused" showed up at the court with cashier's checks for the full amount.
