(1) DISTRIBUTION OF INCOME. Except as otherwise determined by the trustee or a court under s. 701.1106 with respect to unitrust distributions, if a trust instrument fails to specify how frequently a current beneficiary is to receive income from the trust, the trustee shall distribute the income to which the current beneficiary is entitled at least annually.
(2) PERMITTED ACCUMULATIONS. No provision directing or authorizing accumulation of income is invalid.
(3) CHARITABLE TRUST ACCUMULATIONS. A trust containing a direction or authorization to accumulate income from property devoted to a charitable purpose shall be subject to the general equitable supervision of the court with respect to any such accumulation of income, including its reasonableness, amount and duration.
(4) DISPOSITION OF ACCUMULATED INCOME. Income not required to be distributed by the trust instrument may, in the trustee’s discretion, be held in reserve for future distribution as income or be added to principal subject to retransfer to income of the dollar amount originally transferred to principal. At the termination of the income interest, any undistributed income shall be distributed as principal.
