2 The number of certain types of withdrawals from MMIA in a statement cycle is limited, see the Comerica Business and Personal Deposit Account Contract for details. MMIA and High Yield MMIA withdrawal fees apply to excessive withdrawals, transfers or debt transactions.  These transaction types include: checks written by you which clear the account during the statement cycle; ATM or Check Card purchases, withdrawals and transfers; telephone/IVR transfers; check printing fees; Web Banking transfers and payments; ACH debits and any other electronic withdrawals the account holder authorizes.

3 Ledger Balance is the balance in your account that reflects posted transactions, which include deposits, credits, withdrawals and other debits. The average Daily Ledger Balance is calculated by adding the Ledger Balance in the account for each day of the period and dividing that figure by the number of days in the period.

4 For a combined statement, “month” is based on statement cycle date.
