Mrs$.$ Sam Taffer was a brilliant engineer at IBM and made a lot of money from stock options. Since then, she has worked as a musician and raised her two sons. She wishes to have most of her property ultimately pass to them. In a move designed to help achieve this goal, she gifted a substantial amount of her property to a trust in their favour $15$ years ago. The taxation year of the trust ends on December $31,$ and Mrs$.$ Taffer has no beneficial interest in either the income or capital of the trust. The terms of the trust provide for the older son, Jonathan, age $38,$ to receive $35\%$ of each type of income of the trust, while the younger son, Robert, age $35,$ is to receive a $25\%$ share. Trust income includes any capital gains earned in the trust. Both Jonathan and Robert Taffer are single and have no income other than income from the trust. The undistributed income is to accumulate within the trust, to be paid out to the two sons at the time of Mrs$.$ Sam Taffer$$s death. The reported trust income for the $20$XX taxation year is as follows:
