What does maximum value of account mean (for Box 22 on the FBAR)?
The maximum value of account is the largest amount of currency and non-monetary assets that appear on any quarterly or more frequent account statements issued for the applicable year. If periodic account statements are not issued, the maximum account value is the largest amount of currency or non-monetary assets in the account at any time during the year. Convert foreign currency by using the official exchange rate at the end of the year. The value of stock, other securities or other non-monetary assets in an account reported on TD F 90-22.1 (PDF) is the fair market value at the end of the calendar year. If the asset is withdrawn from the account, the value is the fair market value at the time of the withdrawal.
