SECTION 403. BUSINESS AND OTHER ACTIVITIES CONDUCTED BY TRUSTEE.

(a) If a trustee who conducts a business or other activity determines that it is in the best interest of all the beneficiaries to account separately for the business or activity instead of accounting for it as part of the trust's general accounting records, the trustee may maintain separate accounting records for its transactions, whether or not its assets are segregated from other trust assets.

(b) A trustee who accounts separately for a business or other activity may determine the extent to which its net cash receipts must be retained for working capital, the acquisition or replacement of fixed assets, and other reasonably foreseeable needs of the business or activity, and the extent to which the remaining net cash receipts are accounted for as principal or income in the trust's general accounting records. If a trustee sells assets of the business or other activity, other than in the ordinary course of the business or activity, the trustee shall account for the net amount received as principal in the trust's general accounting records to the extent the trustee determines that the amount received is no longer required in the conduct of the business.

(c) Activities for which a trustee may maintain separate accounting records include:

(1) retail, manufacturing, service, and other traditional business activities;

(2) farming;

(3) raising and selling livestock and other animals;

(4) management of rental properties;

(5) extraction of minerals and other natural resources;

(6) timber operations; and

(7) activities to which Section 414 applies.

Purpose and scope. The provisions in Section 403 are intended to give greater flexibility to a trustee who operates a business or other activity in proprietorship form rather than in a wholly-owned corporation (or, where permitted by state law, a single-member limited liability company), and to facilitate the trustee's ability to decide the extent to which the net receipts from the activity should be allocated to income, just as the board of directors of a corporation owned entirely by the trust would decide the amount of the annual dividend to be paid to the trust. It permits a trustee to account for farming or livestock operations, rental properties, oil and gas properties, timber operations, and activities in derivatives and options as though they were held by a separate entity. It is not intended, however, to permit a trustee to account separately for a traditional securities portfolio to avoid the provisions of this Act that apply to such securities.

Section 403 permits the trustee to account separately for each business or activity for which the trustee determines separate accounting is appropriate. A trustee with a computerized accounting system may account for these activities in a "subtrust"; an individual trustee may continue to use the business and record-keeping methods employed by the decedent or transferor who may have conducted the business under an assumed name. The intent of this section is to give the trustee broad authority to select business record-keeping methods that best suit the activity in which the trustee is engaged.

If a fiduciary liquidates a sole proprietorship or other activity to which Section 403 applies, the proceeds would be added to principal, even though derived from the liquidation of accounts receivable, because the proceeds would no longer be needed in the conduct of the business. If the liquidation occurs during probate or during an income interest's winding up period, none of the proceeds would be income for purposes of Section 201.

Separate accounts. A trustee may or may not maintain separate bank accounts for business activities that are accounted for under Section 403. A professional trustee may decide not to maintain separate bank accounts, but an individual trustee, especially one who has continued a decedent's business practices, may continue the same banking arrangements that were used during the decedent's lifetime. In either case, the trustee is authorized to decide to what extent cash is to be retained as part of the business assets and to what extent it is to be transferred to the trust's general accounts, either as income or principal.
