Our customer has frequent casino transactions and also frequent cash deposits. The debits from the casino add up to be pretty close to the cash deposit amounts, so it appears that the casino is the source of the cash. Customer is averaging $50,000.00/month in casino debits and $50,000.00/month cash deposits. The cash deposits average between $4,000.00 to $6,000.00 total per day, none of the cash deposits have been CTR reportable. Gambling is not illegal, and none of the cash transactions are close to the CTR threshold, but due to the high amount of cash being deposited I'm wondering if this could be considered structuring?
