Meaning
Equitable tracing principles limit the proprietary claim of a trust beneficiary to the lowest balance that a commingled bank account has reached during the period between the deposit of the misappropriated trust funds and the date of the claim. Under the lowest intermediate balance rule, if the account balance falls below the amount of the trust money, any subsequent deposits made by the trustee from other sources are not treated as trust property. This limitation stops applying if the trustee deposits new funds with the specific intention of restoring the trust money to the account.
Allocation Rule
Financial analysts apply this principle to determine the maximum value of a proprietary claim when a fraudulent fiduciary has systematically dissipated funds from a mixed account. In cases of investment fraud, applying the lowest intermediate balance rule prevents the first group of victims from claiming funds that were subsequently deposited by later investors. This prevents the unfair enrichment of early investors at the expense of later ones.
Mathematical Application
Calculation of the claim requires a chronological analysis of all transactions in the account from the moment the trust funds were deposited. For example, if a trustee deposits fifty thousand dollars of trust money into an account with a zero balance, withdraws forty thousand dollars, and then deposits twenty thousand dollars of their own money, the beneficiary’s claim is limited to ten thousand dollars. This calculation reflects the lowest balance the account reached before the subsequent deposit.
Procedural Limit
Claimants who cannot recover their full loss through proprietary tracing because of this rule must pursue a personal claim against the trustee for the remaining balance. While the personal claim is a remedy on paper, it is often of little value if the trustee is insolvent. This makes the rule a critical factor in determining the practical recovery of assets.
