Why did my account have a Regulatory Fee Adjustment?

Adjustments are made at the end of each week

If you're somebody that likes to look at their receipt after you purchase something to make sure you were probably charged, then you probably noticed a cash transfer line item titled "Regulatory Fee Adjustment" appear in your History tab at the end of each week. Adjustments made to your account can be a debit or a credit.
