An overdraft occurs when you don't have enough money in your account to cover a transaction, but we pay it anyway. Due to recent changes in banking regulations, you must now Opt-In to receive Overdraft coverage. Please click on the following link to give MCU the authorization to pay overdrafts on ATM and one-time debit transactions. MCU Opt-In Authorization. After August 15, 2010 we'll not authorize and pay overdrafts for ATM transactions and one-time debit card transactions unless you Opt-In.
