Okla. Stat. tit. 60, § 60-175.302: Apportionment of receipts and disbursements when

decedent dies or income interest begins.

APPORTIONMENT OF RECEIPTS AND DISBURSEMENTS

WHEN DECEDENT DIES OR INCOME INTEREST BEGINS

A. A trustee shall allocate an income receipt or disbursement

other than one to which paragraph 1 of Section 5 of this act applies

to principal if its due date occurs before a decedent dies in the

case of an estate or before an income interest begins in the case of

a trust or successive income interest.

B. A trustee shall allocate an income receipt or disbursement

to income if its due date occurs on or after the date on which a

decedent dies or an income interest begins and it is a periodic due

date. An income receipt or disbursement must be treated as accruing

from day to day if its due date is not periodic or it has no due

date. The portion of the receipt or disbursement accruing before

the date on which a decedent dies or an income interest begins must

be allocated to principal and the balance must be allocated to

income.

C. An item of income or an obligation is due on the date the

payer is required to make a payment. If a payment date is not

stated, there is no due date for the purposes of this act.

Distributions to shareholders or other owners from an entity to

which Section 10 of this act applies are deemed to be due on the

date fixed by the entity for determining who is entitled to receive

the distribution or, if no date is fixed, on the declaration date

for the distribution. A due date is periodic for receipts or

disbursements that must be paid at regular intervals under a lease

or an obligation to pay interest or if an entity customarily makes

distributions at regular intervals.
