How to handle 1099-Int and 1099-DIV for a custodial account

I received a 1099-INT and a 1099-DIV for a custodial account for my son. Both forms are for the same account. The form clearly shows me as a custodian for my son. I am claiming my son as my dependent on my return. He is currently in an undergraduate study program that he started last fall. 

 

He earned some income last year through a summer internship. The income was <$3,400 well below the IRS threshold to file but he is still planning to file a return this year to get back the federal tax that was withheld from his paycheck. He is going to check the box that "someone can claim him as a dependent on their return" when filing. My question is who should be showing the 1099-INT and 1099-DIV on their returns. Is it me as a parent or is it him?
