Bobby was very successful in his career, and although he had no children of his own he shared his success with his family. Bobby's sister, Katie, had a son named Joe in 2015. In that same year, created a trust for her nephew's benefit. The trust instrument provided that the income from the principal should be accumulated in the trust until Joe turned 18 years old, at which time the prin and accumulated income would be distributed to Joe. The trust provided that in any year in which Bobby makes a contribution to the trust, any and all beneficiaries of the trust have an unrestricted to withdraw from the trust an amount equal to the annual exclusion under $ 2503(b) applicable for the year of the contribution; the trust also indicated that this withdrawal right will expire 30 days: the date of the contribution to the trust

At the time the trust was created in 2015, Bobby wasn't sure if Katie would have any more children. As a result, Bobby reserved the right to change the beneficiaries of the trust. She also reserved the right to revoke the trust, as well as change the terms of the trust. When Katie later gave birth to a daughter (named Mary), Bobby modified the trust to have included Mary (the modification is described below).

Below is a summary of events that occurred:
