The trust is an accumulation trust and the trust beneficiaries are not entitled to make a demand for any principal or income for a period of years. There are five beneficiaries of the trust and one trustee. During the current year Walter contributed $50,000 to the trust, none of which could a beneficiary receive during the current year.
