(a) Distribution of net income.--Each beneficiary described in section 8121(4) (relating to determination and distribution of net income) is entitled to receive a portion of the net income equal to the beneficiary's fractional interest in undistributed principal assets, using values as of the distribution date. If a fiduciary makes more than one distribution of assets to beneficiaries to whom this section applies, each beneficiary, including one who does not receive part of the distribution, is entitled, as of each distribution date, to the net income the fiduciary has received after the date of death or terminating event or earlier distribution date but has not distributed as of the current distribution date.

(b) Allocation of net income.--In determining a beneficiary's share of net income, the following rules apply:

(1) The beneficiary is entitled to receive a portion of the net income equal to the beneficiary's fractional interest in the undistributed principal assets immediately before the distribution date, including assets that later may be sold or applied to meet principal obligations.

(2) The beneficiary's fractional interest in the undistributed principal assets must be calculated without regard to property specifically given to a beneficiary and property required to pay pecuniary amounts.

(3) The beneficiary's fractional interest in the undistributed principal assets must be calculated on the basis of the aggregate value of those assets as of the distribution date without reducing the value by any unpaid principal obligation.

(c) Collected but undistributed net income.--If a fiduciary does not distribute all of the collected but undistributed net income to each person as of a distribution date, the fiduciary shall maintain appropriate records showing the interest of each beneficiary in that net income.

(d) Application.--To the extent that the fiduciary considers it appropriate, if this section applies to the income from an asset, the fiduciary may apply the rules in this section to net gain or loss from the disposition of a principal asset realized after the date of death or terminating event or earlier distribution date.

(e) Distribution date.--For purposes of this section, the distribution date may be the date as of which the fiduciary calculates the value of the assets if that date is reasonably near the date on which assets are actually distributed.
