Please help me figure out the value !! I do not have more info this is all i have for the question. I already submitted this in accounting of chegg and no one can help so hopefully some one in finance can.

Assume that Benny gives his brother a 10-year term interest in the $2 million home on April 15, 2019. After Bretts 10-year term interest has expired, the remainder interest in the home will go solely to his niece Katie. What is the value of Bretts 10-year term interest for gift tax purposes?
