        <footnote id="F1">Reporting Person is filing an amendment to her Form 4, which was filed on October 4, 2016, in order to update the number of securities acquired and the amount of securities beneficially owned following the Reported Transaction.  On October 1, 2016, Margaret A. Breya was awarded director restricted stock units (&quot;RSUs&quot;) with a value of $84,645, pursuant to the LSC Non-Employee Director Compensation Plan, for her service on the LSC Communications, Inc. (&quot;LSC&quot;) board of directors up until the next annual meeting of LSC stockholders.  Such grant represents 3,222 RSUs calculated based on the twenty trading day volume weighted average price of LSC common stock following the date of grant.  Ms. Breya's RSUs will vest and be payable in shares of common stock one year from the date of grant or when the Reporting Person ceases to be a director, if earlier.</footnote>
