                 FORM 10-K FOR FISCAL YEAR ENDED DECEMBER 31, 2005

Ladies and Gentlemen:

     This letter responds to the Staff's comment letter dated June 20, 2006
regarding the Company's Current Reports on Form 8-K filed on February 16, 2006
and May 11, 2006. For your convenience, the Staff's comment has been reproduced,
followed by the Company's response.

Form 8-Ks filed on February 16, 2006 and May 11, 2006
- -----------------------------------------------------

1.   We note your response to prior comment number 5 with respect to your use of
     the non-GAAP adjusted earnings financial measure. We do not believe that
     you have adequately addressed the usefulness of your non-GAAP measure
     presented. Note, Question 8 of the Frequently Asked Questions Regarding the
     Use of Non-GAAP Financial Measures states, "companies must meet the burden
     of demonstrating the usefulness of any measure that excludes recurring
     items." Therefore, you must either demonstrate the usefulness of your
     non-GAAP measure or eliminate such measure from your disclosure based on
     this guidance. In this respect, please address the following:

     -    Your response indicates that the items excluded in your non-GAAP
          measure "are distinguishable from the Company's core papermaking
          business." Explain why you believe that your core papermaking business
          does not include the expenses and gains/losses that are excluded from
          your non-GAAP results, when such items generally result from your
          operating activities. For example, indicate why your core business
          reflects the benefits of revenue generated from acquired businesses
          but does not reflect the merger integration costs. It appears that
          there would be other costs of such acquisitions that are not being
          eliminated from each measure. Address why you believe that excluding
          certain charges is a proper reflection of your core business. Address
          why the measure includes the revenues but not all

          the cost associated with generating that revenue. Describe the
          economic substance behind management's decision to use each non-GAAP
          measure presented that excludes these non-cash charges.

     -    Your response indicates that the items excluded from your non-GAAP
          measure "will only have an impact over a finite period of time."
          Explain how you have made this conclusion when you have recognized
          gains on the disposition of timberlands and restructuring charges in
          each of the fiscal years ended December 31, 2003 through December 31,
          2005. Further, we note that you have recognized insurance recoveries
          in the fiscal years ended December 31, 2004 and 2005. Therefore, you
          appear to have a past pattern of incurring such charges and
          recognizing such gains. Demonstrate why you believe that you will not
          incur such charges or recognize such gains in the future. We refer you
          to Question 9 of the Frequently Asked Questions Regarding the Use of
          Non-GAAP Financial Measures.

     -    Your response indicates that your papermaking businesses' performance
          can be "obscured" without excluding the "special items" from your GAAP
          results. Further clarify why you believe that your non-GAAP results
          provide a clearer indication of your past and future results than your
          results reported in accordance with GAAP.

     RESPONSE: Our non-GAAP financial measure that we refer to as "adjusted
     earnings" is meant to present the financial performance of the Company's
     core papermaking operation, which consists of the production and sale of
     specialty papers and long fiber and overlay papers, each of which is
     produced at distinct and separate manufacturing facilities. In evaluating
     the performance of our papermaking operations in relation to prior periods,
     management and our Board of Directors focus, and we believe investors
     focus, on business unit financial performance measures related to our
     production and sale of our products. The performance of our papermaking
     operations is evaluated based upon numerous items such as tons sold,
     average selling prices, gross margins and overhead, among others. We
     exclude gains on sales of timberlands, restructuring charges, merger
     integration costs and insurance recoveries in our calculation of adjusted
     earnings because we believe (i) each of these items is unique and not part
     of our core papermaking business and, therefore, not indicative of the
     underlying financial performance of such business and (ii) will only
     impact our financial results for a limited period of time, which is
     determinable. Below, for each of the excluded items, is an explanation of
     the basis for such statements:

          Timberland Sales. Gains from our timberland sales do not represent
          revenue derived from our production and sale of paper products.
          Rather, such gains are the result of the disposition of long held
          assets to monetize the value of such assets and to utilize the
          proceeds to maintain the financial strength and flexibility of our
          balance sheet. Management believes it is appropriate to exclude from

          earnings the gains from such sales because they do not reflect how the
          Company is performing in its paper making operations. We have recently
          publicly disclosed our strategy to complete the disposition of
          additional timberlands within three to five years. Prior to this
          strategy, we sold certain tracts of our timberland in 2003, 2004 and
          2005 in a limited number of discreet transactions. Since any material
          timberland sales are anticipated be completed no later than the end of
          2010, we have concluded that timberland sales will impact our
          financial results for only a finite period of time.

          Restructuring Activities. Earnings are adjusted to exclude the costs
          associated with our discrete restructuring activities because they
          represent charges related to strategic actions taken to reposition the
          business, reduce production costs and/or rationalize assets. We have
          undertaken four specific restructuring initiatives at three of our
          facilities since the fourth quarter of 2002. We believe it is
          appropriate to exclude such charges from our results because these are
          unique charges isolated and identifiable with strategic initiatives,
          and not representative of ongoing costs associated with the production
          and sale of our paper products. Each initiative was implemented in
          response to a specific set of circumstances, market conditions and/or
          other environmental factors affecting the facility's operations. The
          most significant of the restructuring initiatives were the 2004 North
          American Restructuring Program (the "NARP") and the restructurings at
          our operations in Neenah, Wisconsin. The NARP was an initiative
          focused on reducing the cost structure at our Spring Grove facility
          and improving financial results of our Specialty Papers business unit,
          which consisted of a significant workforce reduction and other
          actions. The Neenah restructuring was completed in two separate
          initiatives; an initial restructuring in the second half of 2003 and,
          in connection with our recent acquisition of the facility in Ohio, a
          shutdown of the facility in the first half of 2006.

          Going forward, we are not planning on undertaking any further
          significant restructuring initiatives. However, we are analyzing
          operations at our recently acquired Ohio and United Kingdom facilities
          to determine if restructuring initiatives at either of those
          facilities would be prudent. Restructuring activities, if any, at our
          new facilities are expected to be completed at or before the end of
          2007. We believe that any restructuring activities will only have an
          impact on our financial results over a short period of time because
          they will be completed at the latest by the end of 2007.

          Merger Integration Costs. The two acquisitions we completed in early
          2006 were the first acquisitions we completed since 1998. We have not
          been, and do not anticipate being in the near term, a highly
          acquisitive organization. Each acquisition represents unique isolated
          transactions. Integration costs that have been excluded to arrive at
          adjusted earnings consist primarily of one time external consulting
          costs incurred for projects such as the of redesign our organizational

          structure and the design and implementation of post merger
          transitional planning activities. Such items are one-time costs and
          have been excluded due to their unique and non-recurring nature.
          Management does not include these charges in evaluating the
          performance of our business because they do not represent ongoing
          costs associated with the production and sale of paper products. We
          have concluded that merger integration costs will only have an impact
          over a finite period of time because we do not anticipate completing
          any significant acquisitions in the near term. All material merger
          integration costs related to our recent acquisitions will be incurred
          and expensed by the end of 2006.

          Insurance Recoveries. Gains from insurance recoveries are merely the
          reclamation of prior environmental expenses for which we were insured
          and are not derived from our production and sale of paper products. We
          recognized insurance recoveries during 2004 and 2005. However, as we
          publicly disclosed, we do not anticipate receiving any additional
          significant insurance recoveries in the foreseeable future as we are
          not pursuing any additional claims at this time. As a result,
          insurance recoveries will have no material impact on our financial
          results for the foreseeable future.

          With the exception of insurance recoveries, as discussed below, for
     each of the items excluded from adjusted earnings, we believe our treatment
     of such item has been consistent and all costs and gains associated with
     such item for the applicable period have been excluded from such non-GAAP
     measure. Specifically, the adjustment for merger integration costs
     represents all costs incurred that are not otherwise included as part of
     purchase price accounting adjustments. However, adjusted earnings in the
     periods for which insurance recoveries were recorded was not adjusted to
     eliminate any related legal expenses incurred in such periods in pursuit of
     such claims, primarily due to the immateriality of such amounts. Based on
     the Staff's comment, going forward, we will exclude from adjusted earnings
     all amounts associated with such excluded items recorded in the applicable
     period.

          As discussed above, we believe that the excluded items are unique and
     not part of our core papermaking business and should not be considered in
     evaluating the performance of such operations. As a result, we believe
     gains represented by such items should not be included in a measure of our
     core operations and we believe that the costs associated with the excluded
     items are not costs directly associated with the generation of revenue from
     our core operations. Gains from timberland sales and insurance recoveries
     are distinct from revenues generated from paper product sales and, unlike
     items such as cost of raw materials and overhead costs, restructuring costs
     and merger integration costs are unique items that do not represent direct
     costs incurred in the manufacture and sale of our products.

          Management uses adjusted earnings because it is a measure of the
     performance of the Company's fundamental business, the manufacture and sale
     of paper products.

     Adjusted earnings provides a measure of how core operations are performing,
     which we believe is useful to investors because it allows comparison of
     such papermaking operations from period to period without the taint of
     unique items that, while required to be included in results reported in
     accordance with GAAP, are not directly associated with papermaking.
