After you enroll, you can move to a higher Preferred Rewards for Business tier — and enjoy more benefits and rewards — by increasing your qualifying Bank of America deposit and/or Merrill investment balances. Each month, we'll review your qualifying balances and you'll automatically move to a higher tier when those balances qualify you for the next level of rewards. Here's an example: You've been a Preferred Rewards for Business Gold tier member for six months, with an average combined daily balance in your Bank of America and Merrill accounts of $30,000. If your average balance reached $55,000 in month seven and $95,000 $70,000 in month eight, you'd qualify for the Platinum tier because your three-month average daily balance would be $51,667.
