(a) That you owe the debt;

(b) The amount and basis of the debt; and

(c) That the Endowment has complied with the requirements of 31 U.S.C. 3716, its own administrative offset regulations in this subpart, and the applicable provisions of the Federal Claims Collection Standards with respect to providing you with due process.
