1 Minimum balance to earn the stated Annual Percentage Yield (APY) depends upon the tier as indicated in rates. If the account balance falls below the minimum stated for a particular tier, the next lowest tier's APY will apply. For example, if an account meets the minimum balance requirements for Tier 2 at the start of the dividend period, but the balance subsequently falls below the minimum balance requirement for Tier 2 during the same dividend period, then the account will earn the stated APY for the corresponding Tier 1 account.
