Item 4. Purpose of Transaction.

Item 4 is hereby amended to add the following: 

On October 22, 2013, Starboard Value LP (“Starboard”) delivered a letter to the Issuer’s President and CEO, Henry C. Newell, and the Issuer’s Board of Directors (the “Board”). Starboard had privately sent two letters to Mr. Newell and the Board since May 2013 and had engaged in discussions with management and the Board regarding the issues outlined in the letters.  Starboard stated that the purpose of this public letter is to make Starboard’s thoughts and perspectives on the Issuer as explicit as possible for management and the Board and to share Starboard’s views with the Issuer’s shareholders regarding the significant value creation opportunities at the Issuer, so they too can fully understand the substantial prospects for enhancing value.Specifically, in the letter, Starboard urged the Issuer to (i) immediately initiate a share repurchase of $100 million or more, (ii) institute a recurring dividend of $1.00 per share beginning later this year or early next year, and to increase the dividend to $1.50 or more over time, and (iii) reduce corporate overhead and relocate the Issuer’s headquarters to one of its tissue facilities.  Additionally, in the letter, Starboard highlighted certain other opportunities for improvement at the Issuer, including changes to the scheduling of the Issuer’s earnings calls and changing the Issuer’s name to better reflect and capture the ongoing business.

The full text of the October Letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
