§ 8144. Principal receipts.

    A trustee shall allocate to principal any of the following:

    (1) To the extent not allocated to income under this chapter, assets received from:

    (i) a transferor during the transferor's lifetime;

    (ii) a decedent's estate;

    (ii) a trust with a terminating income interest; or

    (iv) a payor under a contract naming the trust or its trustee as beneficiary.

    (2) Money or other property received from a principal asset's sale, exchange, liquidation or change in form.  This paragraph includes realized profit subject to this subchapter.

    (3) Amounts recovered from third parties to reimburse the trust because of disbursements described in section 8162(a)(8) (relating to mandatory disbursements from principal) or for other reasons to the extent not based on the loss of income.

    (4) Proceeds of property taken by eminent domain.  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.

    (6) Other receipts as provided in sections 8148 (relating to insubstantial allocations not required) through 8155 (relating to asset-backed securities).
