SECTION 404. PRINCIPAL RECEIPTS. A trustee shall allocate to principal:

(1) to the extent not allocated to income under this [Act], assets received from a transferor during the transferor's lifetime, a decedent's estate, a trust with a terminating income interest, or a payer under a contract naming the trust or its trustee as beneficiary;

(2) money or other property received from the sale, exchange, liquidation, or change in form of a principal asset, including realized profit, subject to this [article];

(3) amounts recovered from third parties to reimburse the trust because of disbursements described in Section 502(a)(7) or for other reasons to the extent not based on the loss of income;

(4) proceeds of property taken by eminent domain, but a separate award made for the loss of income with respect to an accounting period during which a current income beneficiary had a mandatory income interest is income;

(5) net income received in an accounting period during which there is no beneficiary to whom a trustee may or must distribute income; and

(6) other receipts as provided in [Part 3].

Eminent domain awards. Even though the award in an eminent domain proceeding may include an amount for the loss of future rent on a lease, if that amount is not separately stated the entire award is principal. The rule is the same in the 1931 and 1962 Acts.
