The new rule applies to overdraft protection programs in which the credit union charges a fee for paying an ATM or a one-time debit card transaction when the member does not have sufficient available funds in the account to cover the transaction. 

The rule does not apply to the payment of overdrafts pursuant to: 

• Any line of credit subject to Regulation Z (Truth in Lending Act (TILA)); 
• Any service that transfers funds from another deposit account held by you (such as the transfer of funds from a savings account to a share draft account); or 
• A line of credit or other transaction in a securities or commodities account that is exempt from Regulation Z.
