Watch out for these types of red flags in your agent's behavior:
• Close relationships with government officials
• Undue secrecy
• Being told "not to ask"
• Inflated invoices or unusual rebates
• Unexplained or large bonuses or expense reports
• Payments to third parties
• Payments in third countries
• Off-books accounts or "slush funds"
• Unusual payments
• Anything that is "not quite right"
Never be afraid or reluctant to challenge something that does not make sense to you or that appears suspicious.
