I'm not sure having a Big 4 auditor means much given that many of the fraud companies employed them, or at least their Asian branches. The advantage AERL has in this regard is they partner with public companies who are themselves audited. The redundancy with which revenue is verified (the casinos, the Macau gaming authorities, the Macau taxing authorities, independent audit teams from AERL's and the casinos' accounting firms) is without equal.
