A manager at a financial institution is assessing the cash flow requirements of the institution's largest customers using the available funds gap (AFG) model. The manager obtains the following current and projected inflows and outflows of funds:

| Item | Amount |

|------|--------|

| Deposits received today | USD 60 million |

| Approved new loan requests | USD 57 million |

| Expected drawdown on corporate client's credit lines | USD 16 million |

| Deposit inflows expected within the next week | USD 12 million |

| 10-year Treasury securities expected to be purchased this week | USD 35 million |

| Other customer funds available today | USD 45 million |

Assuming all else is held constant, if the institution's objective is to maintain an AFG of zero, what is the maximum amount of unexpected customer withdrawals it can meet within the next week?
